Abstract:

There are many classifications of jaw cystic formations. The most perfect is the International histological classification of odontogenic tumors, cystic lesions of the jaws and tumor-like processes, approved by WHO in 1971. According to WHO, the group of epithelial cysts includes both developing ones, including odontogenic (primordial or keratocyst, gingival, erupting, follicular) and non-ontogenic origin (nasopalatine duct, globular-maxillary, nasolabial or so-called naso-alveolar), and inflammatory (radicular) tumor-like formations.

Abstract:

Odontogenic Keratocyst is an aggressive odontogenic cyst with a high recurrence rate. After radicular and follicular cysts, odontogenic keratocysts are the third most common cyst of the jaws and approximately 12-14% of all odontogenic cysts. It has been retermed to Keratocystic odontogenic tumour (KCOT) as it better reflects its neoplastic nature but recently it has been re classified and retermed into the cystic category. Various surgical methods have been proposed but comparatively, conservative treatment options such as Dredging methods might be the treatment of choice due to preservation of anatomical structure. Objective: The aim of this study was to analyse the clinical, radiological and histopathological characteristics of Odontogenic Keratocyst and provide a proper management system affected by this type of lesions. Materials and methods: The prospective study was performed in Dhaka Dental College and Hospital from a period of January 2014 to January 2018. A total number of 75 patients were selected for this study based on clinical, radiological and histopathological confirmation of odontogenic keratocysts. The treatment options were enucleation, enucleation with curettage, enucleation with peripheral ostectomy, Dredging method and surgical resection. After treatment patients were followed up 1months, 3 months and 6 months in every year at least for 5 years. Results: Among 75 patient of odontogenic keratocyst; the mean age was 27.69±13.35 and age range was 11 to 66 years. Male were 53(71%) and 22 (29%) were female patients. 53 (70.67%) cases were found in the mandible, 15(20%) cases in the maxilla and in 7(9.33%) cases were involved in both maxilla and mandible; mandibular posterior region was the most specific region involved 37(69.81%).The most common clinical features revealed pain and swelling. Radiologically, 70.66% unilocular, 96% well defined and 94.66% radiolucent area were prominent. Bone expansion 37.38%, root resorption 30.00% and 36% were associated with an impacted tooth. Regarding treatment options enucleation with curatage 12%, enucleation, curettage & peripheral ostectomy 29.33%, Dredging 52% and surgical resection 6.6% was done. Recurrence occurred in 18 patients with recurrence rate of 24%. Conclusion: Odontogenic keratocyst is an aggressive cyst, male predominant, posterior mandible is the commonest site and well defined unilocular radiolucency are commonest radiological feature. Radical treatment options such as resection reduced the recurrences of the tumour but higher morbidity and jaw deformity. Comparatively, conservative treatment options such as Dredging methods might be the treatment of choice due to preservation of anatomical structure. A long term follow up is paramount importance for the research and understanding the clinical pattern, behavior, treatment and recurrence of the lesion. Update Dent. Coll. j: 2019; 9 (1): 8-15

Abstract:

AbstractPanfolliculoma is a rare follicular neoplasm with differentiation toward both upper (infundibulum and isthmus) and lower (stem, hair matrix, and bulb) segments of a hair follicle. We present an unusual case of cystic panfolliculoma. A 33-year-old Hispanic woman presented with an 8-month history of a 3.0-cm cystic scalp mass. The lesion was excised, and the histologic sections showed a cystic follicular neoplasm that contained corneocytes in basket-woven and laminated array, trichohyalin granules of the inner root sheath, germinative cells, papillae, matrical cells, and “shadow” cells. Cytokeratin 903 and cytokeratin 5/6 immunostains uniformly highlight the tumor cells. Ber-EP4 strongly labels the germinative cells but not the follicular papillae. CD34 labels the surrounding fibrotic stroma and focally the epithelial component.

ABSTRACT Cystic lesions are frequent in the oral cavity. They are defined as a pathologic cavity with or without fluid or semifluid material. Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin affecting the jaws. They are most commonly found at the apices of the involved teeth. This case report presents the successful surgical management of large infected radicular cyst involving entire body region of right side of mandible. We illustrate the possibility of healing of cystic periapical lesions with conservation of vital structures. How to cite this article Agarwal P, Sharma S, Trehan M, Vashistha A.

Abstract:

TNF-α is a pleiotropic cytokine that is considered as a primary modifier of inflammatory and immune reaction in response to various inflammatory diseases and tumour. We investigated levels of TNF-α in 43 radicular cysts and 15 odontogenic keratocysts, obtained from patients undergoing surgery, under local anaesthesia, and after aspiration of cystic fluid from non-ruptured cysts. TNF-α is elevated in both cysts’ fluid, but higher values were found in radicular cysts in comparison to keratocysts. The significantly higher concentration of TNF-α was associated with smaller radicular cysts, higher protein concentration, higher presence of inflammatory cells in peri cystic tissues, and the degree of vascularisation and cysts wall thickness (Mann-Whitney U-test, p<0.05). No correlation was found based on these parameters in odontogenic keratocyst, but all cysts have detectable concentrations of TNF-α. We here for the first time present that a difference in the concentration of TNF-α exists between these two cystic types.

Abstract:

In response to the prolonged increasing influence of the radicular cyst, there is an adaptive compensatory reaction of the adjacent bone tissue and periosteum located in the area of damage. However, in the available professional literature there is no data on the activity of the marker of osteoregeneration-alkaline phosphatase in the periosteum of the mandible, which is in the growth zone of osteoblastoclastoma. The purpose of the study: to study in a comparative aspect osteoregenerative activity of the periosteum of the mandibular bones affected by radicular cyst and cystic form of osteoblastoclastoma by using the histochemical method. Histochemical studies were performed in 10 patients with large radicular cysts (d>3.0 cm) located on the mandibles – 1st clinical group, and in 9 patients with cystic forms of osteoblastoclastomas, localized on the mandibles - 2nd clinical group. Determination of alkaline phosphatase in periosteal tissues of the mandible was performed by the method of simultaneous azo combination according to Kaplow. Prepared samples of histochemicals were studied under a light microscope, the received images were photographed. Digitized images of histochemicals were analyzed using the computer program ImageJ. The accumulation of alkaline phosphatase in the periosteum of the mandibular areas affected by osteoblastoclastomas is less intense compared to the process of synthesis of this enzyme in the periosteum of the mandible, which is affected by radicular cysts of large size. Osteoregenerative potential of periosteum of mandibular bones affected by radicular cysts is much greater than in the periosteum located in the growth zone of the cystic form of osteoblastoclastoma.

Abstract:

Background: Odontogenic cysts are defined as the epithelial cysts which arise from odontogenic epithelium and occur in tooth bearing regions of jaws. The objective of the present study was to analyze different histopathological types of cystic jaw lesions and to determine the distribution of their relative frequency according to site, sex, size and age group. Materials and methods: This study was a cross sectional hospital based observational study conducted in the Department of Pathology, Manipal Teaching Hospital. All cases with cystic jaw lesions on histopathology during the study period from January 2014 to December 2018 were included in the study. Results: Thirty-two cases of cystic jaw lesions were reported during the study period. Females were more commonly affected in our study with a male: female ratio of 1:1.9. The age range in the study was 9 to 71 years with a mean age of 33.3 years. The most frequent type was radicular cysts followed by dentigerous cysts, odontogenic keratocysts and cystic ameloblastoma. Radicular cysts showed the most female predilection with a ratio of 1:4.3. and a mean age of 35.6 years. Majority of dentigerous cysts were seen in patients below 30 years. Both radicular cysts and dentigerous cysts showed more involvement of maxilla but odontogenic keratocysts were more common in mandible Conclusions: The present study corroborate with other similar literature with respect to the frequency percentage of different types of jaw cysts.However, female predilection was seen in radicular and dentigerous cysts. Maxilla was the more common site except in odontogenic keratocysts.

Abstract:

Radicular cyst as the most common odontogenic cyst usually arises from residual epithelial cells stimulated by inflammatory factors initiating by pulpal necrosis of a non-vital tooth. Radicular cyst is commonly asymptomatic, slow grower, and rarely invade near bony structures. Many treatment approaches are presented for a radicular cyst like surgical endodontic treatment, tooth extraction, enucleation, and marsupialization. In this case treatment plan compromised with root canal therapy and surgical enucleation of cystic lesion. This case report presents a large radicular cyst in a vital maxillary first molar with only one necrotic root canal secondary to direct pulp capping with mineral trioxide aggregate with buccal and palatal cortical bone perforation.

Abstract:

Radicular cyst is the most common odontogenic cystic lesion of inflammatory origin. It is also known as periapical cyst, apical periodontal cyst, root end cyst, or dental cyst. It arises from epithelial residues in the periodontal ligament as a result of inflammation. The inflammation usually follows the death of dental pulp. This paper presents a case report of a patient with radicular cyst associated with a primary molar.

Abstract:

Vascular Endothelial Growth Factor, also known as Vascular Permeability Factor, is a multifunctional cytokine hyperexpressed during angiogenesis and in numerous physiological and pathological processes characterised by an increase of vascular permeability. The aim of this study was to evaluate the angiogenetic processes which are accompanied by an expansion of cystic radicular lesions and of keratocysts of the jaw bone. 12 subjects were chosen with an average age of 43 years, of whom 8 were males and 4 females. After an accurate history and physical examination, the patients underwent surgery for removal of the cysts. The samples taken were histologically and immunohistochemical examined. The histological exam confirmed the diagnosis of radicular cysts and keratocysts. The immunohistochemical examinations were positive for VEGF in all the lesions analysed, even though they had different immunostaining. Using a semi-quantitative method, in the radicular cyst samples it was possible to highlight a wider expression of the vascular component, both in the inflamed area and the adjacent stroma. The lesions with keratin content showed newly formed and modest vascularisation both in the area showing slight inflammation, where the cellular component was prevalent, and in the adjacent areas showing no inflammation. Therefore, angiogenesis could take on a primary role in the development of cystic lesions of the jaw. However, the differences of expression of the VEGF protein suggest the need for wider monitoring to better evaluate a possible use of such a protein as a diagnostic marker.

Abstract:

Background: Published criteria to distinguish benign colloid nodules from follicular neoplasms emphasize only three interdependent features: size of follicles, amount of colloid, and cellularity. There is a need for the validation of other independent criteria. Methods: This study quantified the significance of cystic change, defined as presence of macrophages, and the presence of hemosiderin in either the macrophages or follicular cells. The cohort consisted of 165 patients with fine needle aspiration (FNA) and histologic follow-up of either goiter (101), follicular adenoma (47), or follicular carcinoma (17). Papillary thyroid carcinomas and Hürthle cell neoplasms were excluded from the cohort, because these categories are known to show cystic change and hemosiderin. FNAs were reviewed blindly with the most cellular slide scored for the presence of macrophages and/or hemosiderin. Results: Hemosiderin within macrophages were seen in 67% (68 of 101) of the goiters and only 6% (four of 64) of follicular neoplasms (P<.0001). All four follicular neoplasms with hemosiderin in macrophages were adenomas. Three of these four had equivocal features of a benign colloid nodule histologically. None of the 17 follicular carcinomas had hemosiderin in macrophages (P<.12). Macrophages without hemosiderin also strongly distinguished goiters from neoplasms (83% vs 17%) but appears less useful as a criterion since macrophages were present within 3 of 17 follicular carcinomas. Hemosiderin within follicular epithelial cells was present in 18% (18 of 101) of goiters, whereas none of the 64 follicular neoplasms had intraepithelial hemosiderin (P<.0003). Conclusions: If papillary thyroid carcinoma and Hürthle cell neoplasm are ruled out, our findings indicate that the presence of hemosiderin virtually excludes a clinically significant follicular neoplasm.

Abstract:

The radicular cyst is an inflammatory odontogenic cyst of endodontic origin. Radiographically, the lesion appears as a periapical radiolucent image. This report describes a very rare case of a mixed periapical radiographic image diagnosed as a radicular cyst. A 37-year-old female patient presented a mixed, well-circumscribed image located in the periapical region of the left maxillary central incisor, which presented unsatisfactory endodontic treatment. Microscopic examination revealed a cavity lined by non-keratinized squamous epithelium and extensive calcifications in the cystic lumen and lining epithelium. Diagnosis of radicular cyst with extensive calcifications was established. Endodontic retreatment was performed and no radiographic signs of recurrence were observed 18 months after treatment. Although very rare, a radicular cyst should be considered in the differential diagnosis of a mixed periapical image associated to teeth with pulp necrosis.

ABSTRACT Radicular cysts are the most frequent inflammatory cysts comprising of about 52 to 68% of all the jaw cysts. It arises from the epithelial residues in the periodontal ligament space following pulpal necrosis. The distinguished lining of the cystic lumen is hyperplastic stratified squamous nonkeratinizing epithelium showing arcading pattern with dense infammatory cell infiltrate, cholesterol clefts, Russell bodies and Ruston bodies in the connective tissue capsule. Here, we present an unusual large radicular cyst lined almost entirely by quiescent atrophic epithelium, which is innocuous, persistent, has enlarged overtime, with minimal infammatory cells in the connective tissue capsule.

Abstract:

Introduction. Radicular cysts treatment involves surgical approach, more or less aggressive. However, treatment of large cystic lesions, including radicular cysts, causes some of dilemmas concerning the choice of the surgical method, especially the degree of radicalism. Case report. We presented a 65-year-old male patient with large radicular cyst in the mandible. A large elliptical multilocular radiolucency, located in the left side of the mandible, being in close vicinity to the mandibular canal, was registered at the orthopantomographic radiography. There was a risk of pathological fracture of the mandible. However, the cyst was completely removed by enucleation without intraoperative and postoperative complications. Conclusion. The presented case support the opinion that careful enucleation of large mandibular cysts may be done without complications, such as damages of surrounding anatomical structures or mandibular fracture. The authors indicate reasons for strong support of the undertaken surgical approach of treating large radicular cysts in the mandible.

Abstract:

AbstractThe aim of this study was to carry out the metabolic profile comparison between follicular fluid and serum in normal cows and those affected by ovarian cysts (OC). After slaughtering, blood samples and follicular fluids from normal and cystic animals were collected and assayed using commercial kits to determine the concentrations of metabolites (glucose, total protein, total cholesterol, cortisol, triglycerides, urea, creatinine and insulin) and the liver enzymes activity. Data showed that OC were characterized by low levels of glucose, total protein, cholesterol and cortisol in cystic fluid, while urea concentrations were high compared to normal follicular fluid (P<0.001). On the other hand, serum assays of cystic animals revealed very low values of insulin and urea, whereas cortisol levels were relatively high in comparison with the serum of normal cows (P<0.001). Significant correlations between the serum and follicular fluid concentrations of normal cows were found for glucose (r=0.49), total cholesterol (r=0.31), cortisol (r=0.38) and total protein (r=0.63). The highest correlation was found for urea (r=0.86). On contrary, weak correlations were observed between metabolites concentrations in cystic fluid and in serum for normal and cystic cows. In conclusion, OC grow and persist in a metabolic environment, which differs from follicular fluid to blood. These changes may act together and/or separately to ensure the continuous development of OC. To understand a part of the mechanism, the authors propose a deep study about blood-follicle-barrier.

Abstract:

Introduction. Therapeutic approach to jaw cysts may depend on their dimensions and localization. Enucleation of cystic lesion is not always preferable in the first act, especially if large cysts are in close proximity to important anatomical structures. The aim of this paper was to present the outcome of the treatment protocol comprising preoperative decompression and subsequent enucleation of a large maxillary cyst. Case report. A 21-year-old male patient with large asymptomatic radicular cyst in the right maxillary sinus was presented to our clinic. Cone-beam computed tomography (CBCT) showed a large cyst, which perforated the right anterior maxillary wall by 1.5 cm, and was in the intimate contact with the orbital floor. Surgical treatment of the cystic lesion comprised: preoperative decompression with biopsy in the first act and enucleation, performed under general anesthesia, 6 months after the observation period. Conclusion. Decompression with subsequent enucleation proved to be effective treatment of large radicular cyst in maxillary sinus with low-morbidity.

Abstract:

Cystic lesions of jaws are fairly common of which radicular cysts that form as a result of inflammatory changes associated with a non-vital pulp are most frequent. The removal of source of infection by either root canal treatment or extraction of the involved tooth leads to resolution of inflammatory cysts. However, infrequently, certain lesions may persist even after appropriate treatment which are termed as ‘residual cysts’. Although residual cysts are histopathologically indistinguishable from radicular cysts, certain changes may occur owing to removal of the aggravating stimulus which may lead to a varied histopathological picture. The present case report comprises of a residual cyst with a relatively unusual histopathological presentation.

Abstract:

Formation of persistent follicular cysts is a prevalent problem for producers of domestic agricultural animals in North America. The most common group of animals affected is dairy cattle. This condition is problematic as it renders cattle anovulatory and infertile for the duration of the cyst. Various studies have assessed the incidence of follicular cysts in dairy cattle, revealing a range of prevalence of 9–26%. Although there is information regarding the incidence of this disorder, little is known of the etiology. It is known that a complex interaction occurs between the hypothalamus, anterior pituitary, and ovary to regulate normal reproductive function. Dysregulation at any of these sites could contribute to the formation of persistent follicular cysts. The objective of this study was to determine whether local changes in gene and protein expression are present in cystic follicles. Transvaginal aspirations from follicles that had been greater than 2.5-cm diameter for at least 10 days were collected. Aspirates were centrifuged, and granulosa cells and follicular fluid were separated. Granulosa cells were lysed, and RNA and protein was isolated. For immunohistochemistry, bovine slaughterhouse ovaries with follicles greater than 2.5cm in diameter were dissected, fixed, and processed. Western blot analysis and RT-PCR were performed on protein and RNA samples, respectively. Cystic and control follicles were analyzed for expression of vascular endothelial growth factor (VEGF) and its receptor VEGF-R2 and members of the insulin-like growth factor (IGF) family, which are known to mediate a host of cellular events during follicular development. Cystic follicles exhibited a significant increase in VEGF and IGF-I protein concentrations and a reduction in VEGF-R2 and the type 1 IGF receptor. Immunohistochemical analysis demonstrated increased ligand staining and reduced receptor expression in granulosa cells of cystic follicles. These results indicate that there is an altered growth factor profile in cystic follicles and suggest that intra- as well as extra-follicular dysregulation is important in the etiology of this reproductive disorder.

Abstract:

Introduction: Neoplastic ovarian lesions have been extensively studied, but less attention is paid to non-neoplastic cystic lesions. Though follicular cysts are the most common of the non-neoplastic cysts, the % of occurrence of individual non-neoplastic lesions is not known. Also, often there is dilemma in reporting the exact type of nonneoplastic cyst. This study was planned with the objectives of assessing percentage of non neoplastic cystic ovaries, determining the morphological forms and relation of the various cysts with age of patient, and to detect whether multicystic non neoplastic lesions are more frequent in present day. Materials and methods: A prospective hospital based cross sectional non-neoplastic ovarian cysts study was done between January to June 2019 in a tertiary hospital. All hysterectomy specimens with the accompanying ovary/ovaries and oophorectomy specimen were included. Microscopic features were assessed. Data was tabulated in MS excel sheet. Percentage of occurrences of age, size, morphological type, laterality and complaints were calculated. Result:50% of 193 ovaries had non neoplastic cystic lesions. Non neoplastic cysts were associated with fibroid in 54%, DUB in 17% and adenomyosis in 16% cases. They were seen commonly during reproductive age group(83%). Post-menopausal age showed 16% cases. 86% of the non neoplastic ovarian cystic lesions were unilateral. 20% non neoplastic cystic lesions were of <1cm, 74% were 1-5 cm in size and 5% were larger than 5 cm. Morphologically 40% were follicular lesions, 32% were simple serous cysts, 14% were haemorrhagic cysts, 8% corpus luteal cysts and 2% each theca lutein and epithelial inclusion cysts. Conclusion: Non neoplastic cystic ovaries comprised 50% of all ovarian lesions, 83% were seen during reproductive age group. Leiomyoma, dysfunctional uterine bleeding and adenomyosis were the common clinical features and 70% of the cysts were 1-5 cm in size. There was no relation between morphological types of the cystic lesions and functional status. Simple serous cyst, cystic follicle, follicular cyst, cystic corpus luteum, corpus luteal cyst, theca luteal cyst, epithelial inclusion cyst and haemorrhagic cyst were found of which follicular cyst was the commonest (40%) Multicystic non neoplastic lesions or polycystic ovaries were not found during the period of study.

Abstract:

Trichoepithelioma is a benign, cutaneous neoplasm originating from the hair follicle and is categorized into singular trichoepithelioma, multiple trichoepithelioma and desmoplastic trichoepithelioma wherein desmoplastic trichoepithelioma is cogitated as an exceptional, cutaneous adnexal tumour. Desmoplastic trichoepithelioma was initially scripted by Hartzell in 1904 wherein the lesion was described as a benign, cystic epithelioma. Desmoplastic trichoepithelioma can be additionally nomenclated as epithelioma adenoides cysticum, morphea - like epithelioma or sclerosing epithelial hamartoma 1. Familial instances of desmoplastic trichoepithelioma are infrequent and can be misdiagnosed on account of adjunctive benign, cutaneous, adnexal neoplasms depicting subtle clinical features, excepting a nodular basal cell carcinoma. Cogent clinical and histological features can assist the diagnosis of desmoplastic trichoepithelioma 1, 2.

Abstract:

The expression of cytoskeletal proteins was evaluated immunohistochemically in 36 normal ovaries sampled from 18 sows and 44 cystic ovaries sampled from of 22 sows, was evaluated. All sows had history of reproductive problems, such as infertility or subfertility. The immunohistochemically stained area (IHCSA) was quantified through image analysis to evaluate the expression of these proteins in the follicular wall of secondary, tertiary, and cystic follicles. Cytokeratins (CK) immunoreactivity was strong in the granulosa cell layer (GC) and mild in the theca interna (TI) and externa (TE) of the normal follicles. There was severe reduction of the reaction to CK in the GC in the cystic follicles, mainly in the luteinized cysts. The immunoreactivity for vimentin was higher in the GC from normal and cystic follicles in contrast with the other follicular structures. In the luteinized cysts, the IHCSA for vimentin was significantly higher in TI and in both observed cysts, the labeling was more accentuated in TE. Immunohistochemical detection of desmin and α-SMA was restricted to the TE, without differences between the normal and cystic follicles. The results of the current study show that the development of ovarian cysts in sows is associated to changes in the expression of the cytoskeletal proteins CK and vimentin.

Abstract:

ABSTRACT Surgical enucleation of a radicular cyst is a common treatment in endodontics but the pretreatment planning and assessment of the post-treatment healing in the cystic cavity is of utmost importance. The advantage of cone beam computed tomography (CBCT) in endodontics is that it demonstrates anatomic features in three dimensions that is not possible with intraoral periapical (IOPA) and panoramic radiographic images. In this case report, a CBCT was done to evaluate the size and extent of the radicular cyst in the maxillary anterior region and was enucleated. Apicoectomy was done and the hollow cavity was filled with platelet rich fibrin. A postoperative CBCT was done 2 years later to assess the healing. Specific situations, both pre- and postoperatively, where the understanding of spatial relationships afforded by CBCT facilitates diagnosis, influences treatment and assess healing.

Abstract:

Cystic ovarian disease (COD) is an important cause of infertility in cattle. The altered follicular dynamics and cellular differentiation observed in COD may be mediated through a disruption of the expression of steroid receptors and their associated transcriptional cofactors. The aim of this study was to determine the protein expression profiles of ESR1, ESR2, PGR, AR, NCOA3, NCOR2, and PHB2 (REA) in ovarian follicles in an experimental model of COD induced by the administration of ACTH. Ovaries were collected and follicles were dissected from heifers during the follicular phase (control) or from heifers treated with ACTH to induce the formation of ovarian follicular cysts. Ovaries were fixed, sectioned, and stained immunohistochemically for steroid receptors and the associated transcription factors. The relative expression of ESR1 was similar in follicular cysts and in tertiary follicles from both control and cystic cows and was significantly higher than in secondary follicles. The expression of ESR2 in the granulosa was higher in cystic follicles. No differences were seen for PGR. The expression of androgen receptor was significantly increased in tertiary follicles with lower immunostaining in cysts. The expression of NCOA3 was observed in the granulosa and theca with a significantly increased expression in the theca interna of cystic follicles. The highest levels of NCOR2 expression in granulosa, theca interna, and theca externa were observed in cysts. In granulosa cells, NCOR2 levels increase progressively as follicles mature and the treatment had no effect. In summary, ovaries from animals with induced COD exhibited altered steroid receptor expression compared with normal animals, as well as changes in the expression of their regulators. It is reasonable to suggest that in conditions characterized by altered ovulation and follicular persistence, such as COD, changes in the intra-ovarian expression of these proteins could play a role in their pathogenesis.

Abstract:

While cystic follicles remain a significant problem in dairy cows, their aetiology still remains unclear. Recent studies have shown that treatment with low levels of progesterone can interfere with the induction of an LH surge and induce cystic follicles leading to the theory that supra basal concentrations of progesterone may act as a trigger for the formation of cystic follicles (Silvia et al., 2002).

Abstract:

The present study was conducted under field conditions on >90 days postpartum HF crossbred cows with cystic ovaries (n = 58). The diagnosis was confirmed by history and trans-rectal palpation and ultrasonographic examinations twice at weekly interval using 5.0–7.5 MHz frequency probe and was later authenticated with plasma progesterone assay and treatment response. The animals with follicular cysts were randomly treated with either conventional ovsynch or ovsynch + CIDR protocol with fixed time AI (n = 10 each), and those with luteal cysts with either double PG injections 11 days apart or modified Ovsynch protocol (n = 16 each). Among 58 cystic cows, the highest incidence (62.07 %) of the ovarian cyst was recorded in the age group of 5–7 years followed by above 7 years (36.21%) and 3–5 years (2.00%). The incidence was highest among cows of 3rd or more parity (70.69%) followed by 2nd parity (29.31%), and no case was seen in primiparous cows. Of the total 36.21% were follicular type cyst and 63.79% luteal type cysts. The right ovary had a high incidence of the cyst (51.72%) followed by the left ovary (36.21%), and bilateral (12.07%). Based on rectal palpation, the cystic ovary was classified to have follicular cyst in 36.21% (21/58) cases and luteal cysts in 63.79% (37/58). Ultrasound examination showed follicular and luteal cysts as 27.59% and 72.41%, whereas plasma P4 (less than/greator than 1 ng/mL) analysis revealed this as 20.69% and 79.31%, respectively. The clinical diagnosis became more accurate with a combination of per rectal palpation and USG and was further improved by plasma progesterone assay. The mean diameters and a wall thickness of cysts varied highly significantly (p less than 0.01) between groups/protocols. The conception rates at induced estrus with FTAI in cows under ovsynch, ovsynch + CIDR, modified ovsynch and double PG protocols were 50.00, 40.00, 50.00 and 43.75 percent, respectively. It is thus concluded that in crossbred cows luteal cysts are more common than follicular cysts, particularly in prime aged animals of 3rd or 4th parity with more of left ovarian involvement. The differentiation of cyst type is best achieved with the combined use of USG and/or plasma progesterone assay with rectal palpation, and that ovsynch protocol appeared promising for the treatment of follicular cysts and Modified Ovsynch for luteal cysts.

Abstract:

Macromolecular crowding is a general phenomenon of biological systems, and the evaluation of a correlation time for a specific molecule is difficult when the molecular crowding exists. The determination of an effective correlation time may therefore give useful insights into molecular dynamics of such systems. In this work, the relaxation rates in the mixture of D2O (80%) and cystic fluid (20%) were measured with a NMR operating at 400 MHz for three types of cysts (non-infected radicular, infected radicular and hemorrhagic). The effective correlation times (τvalues) were then determined by using a formula derived from the observed relaxation rates. Theτvalue of the infected cyst was found to be longer than those of the others for the studied cases. The present data suggest that an effective correlation time for fluids with macromolecular crowding can be determined from NMR relaxation measurements.

Abstract:

Cystic ovarian disease (COD) is an important cause of subfertility in dairy cattle. Bone morphogenetic proteins (BMPs), mainly BMP2, BMP4 and BMP6, play a key role in female fertility. In this study, we hypothesized that an altered BMP system is associated with ovarian alterations contributing to COD pathogenesis. Therefore, we examined the expression of BMP2, BMP4 and BMP6 and BMP receptor 1B (BMPR1B) in the ovaries of animals with spontaneous or ACTH-induced COD, as well as during the development of the disease, in a model of follicular persistence induced by low doses of progesterone (at 5, 10 and 15 days of follicular persistence). Results showed changes in BMP2, BMP4 and BMP6 expression during folliculogenesis, in granulosa and theca cells in the COD groups, as well as at different stages of follicular persistence. Results also showed changes in BMPR1B expression in developing follicles in animals with COD, and at the initial stages of follicular persistence (P5). Comparison between groups showed significant differences, mainly in BMP4 and BMP6 expression, in granulosa and theca cells of different follicular categories. The expression of these BMPs also increased in cystic and persistent follicles, in relation to antral follicles of the control group. BMPR1B showed high expression in cystic follicles. Together, these results may indicate an alteration in BMPs, especially in BMP4 and BMP6, as well as in BMPR1B, which occurs early in folliculogenesis and incipiently during the development of COD, which could be a major cause of recurrence of this disease in cattle.

Abstract:

Follicular dendritic cell sarcoma is a very rare neoplasm that most commonly involves cervical lymph nodes and usually presents as a solid mass. Presentation as a cystic neck mass is very rare. Radiological studies and aspiration cytology are often unreliable, and diagnosis is usually made after thorough clinical and pathological examination along with immunohistochemical analysis. In this article, we report a case of a 42-year-old man who presented with right-sided neck swelling of a 2-month duration. Contrast-enhanced CT showed a cystic lesion in the right side of the neck inferomedial to parotid gland located between medial border of sternocleidomastoid muscle and internal jugular vein. Fine needle aspiration cytology was inconclusive. Patient underwent excision biopsy. Histological examination showed a solid-cystic tumor composed of spindle cells arranged in storiform pattern and showed a positive staining for CD23, CD35, and CD21 that confirmed the diagnosis of follicular dendritic cell sarcoma.

Abstract:

The expression of cystic fibrosis transmembrane conductance regulator (CFTR) in the thyroid has not been documented to date, although a role for CFTR in the thyroid follicular epithelium is suggested both clinically, by the occurrence of subclinical hypothyroidism in patients with cystic fibrosis (CF), and physiologically, by the presence of low-conductance, adenosine 3',5'-cyclic monophosphate-activated Cl channels in the follicular cells. Using reverse transcriptase-polymerase chain reaction with nested primers derived from exons 13 and 14 of the human CF gene, we have now documented the presence of CFTR mRNA in the human thyroid. Western blot analyses using six antibodies directed against different domains of human CFTR showed that a 165-kDa band was present in membrane extracts from bovine and human thyroid. This protein has the predicted size of mature CFTR and was not detected with preimmune serum or preadsorbed antiserum. By immunofluorescence and immunoperoxidase, CFTR was located in the follicular cells, with a diffuse, intracellular labeling pattern. Quantitative analysis revealed that 64% of the follicles were CFTR positive, but only 16% of the follicular cells were stained per follicle. The number of CFTR-positive cells was inversely proportional to the size of the follicle. These results 1) demonstrate the expression of CFTR at the mRNA and protein levels in human and bovine thyroid follicular cells and 2) suggest that CFTR expression could be instrumental in follicular enlargement.

Follicular bronchiolitis (FB) is a rare bronchiolar disorder associated with hyperplasia of the bronchial-associated lymphoid tissue (BALT). It is characterized by the development of lymphoid follicles with germinal centers in the walls of small airways. It falls under the category of lymphoproliferative pulmonary diseases (LPDs) and commonly occurs in relation to connective tissue disease, immunodeficiency, infections, interstitial lung disease (ILD), and inflammatory airway diseases. Computerized tomography (CT) findings include centrilobular nodules with patchy ground glass infiltrate, tree-in-bud findings, and air trapping. It can very rarely present as diffuse cystic lung disease. We present two cases of FB. The first case is associated with Human Immunodeficiency Virus (HIV) infection and asthma with diffuse cystic changes on the CT. The second case is associated with reactive airway disease and gastroesophageal reflux disease (GERD) with the classic centrilobular nodules and ground glass opacities on the CT.

Abstract:

Background: Basaloid follicular hamartomas (BFH) are rare, benign, adnexal lesions with diverse clinical presentations. Previous studies documented BFHs with fibroepithelioma of Pinkus-like proliferations, or proliferations that resemble trichoepitheliomas. Objective: We report on a patient with linear, unilateral BFH and extensive trichoblastomatous proliferations involving the right arm, torso, and leg. An 18-year-old female presented with multiple, hyperkeratotic, linear nodules and plaques limited to her right side from the shoulder to the leg. The lesions had existed since birth and gradually increased over time. Results: The lesions contained hyperpigmented, exophytic nodules with acanthosis, pseudoepitheliomatous hyperplasia, focally associated with hyperkeratosis, and squamous eddies. Some areas contained trichoepithelioma-like proliferations, or large nodules of basaloid cells with numerous cystic spaces, marked hyperpigmentation, and melanophages. The diagnosis was linear, unilateral BFH with an unusual trichoblastomatous component. Conclusion: While trichoblastomatous proliferations could occur in a BFH, to our knowledge this finding has not been reported.

Abstract:

A cystic structure was identified radiographically in a four year old dog during routine dental prophylaxis. Surgical removal of the cyst lining was achieved by exposure of the site through extraction of the right first to third maxillary incisor teeth (101, 102, 103). The cyst lining was removed en-bloc. The cavity was curetted and filled with decalcified freeze-dried bone. Histological examination revealed a radicular cyst. The proposed etiology is blunt trauma to tooth 103, pulpal necrosis, apical granuloma and resulting cyst formation. Fourteen months following surgery, there was no recurrence of the cyst.

Abstract:

Odontogenic cysts are usually treated by enucleation (cystectomy). Limited cysts (less than 5 cm) are usually managed by primary excision (total cystectomy), whereas larger ones (exceeding 5 cm) are often decompressed or marsupialized. Because it consists only of opening a much smaller surgical window, decompression is regarded as a more conservative method of treatment: this method associates the creation of an opening (window) into the cystic cavity with the suturing of a decompressing device (plastic tube or stent) at the periphery of the cyst. Apart from releasing intraluminal pressure in the pathological cavity, this procedure helps the lesion to progressively decrease in volume “with a gradual increase in bone apposition” and preserves pulp vitality and periodontal integrity of the adjacent teeth. We are reporting a case of a mandibular radicular cyst that was treated by decompression, followed by enucleation, bone reconstruction, and restoration with two osseointegrated dental implants. The cystic cavity progressively decreased in volume and increased in bone density.

Abstract:

Diffuse cystic lung diseases include a group of heterogeneous disorders characterised by the presence of cysts within the lung parenchyma, sometimes showing a characteristic computed tomography scan pattern that allows diagnosis. The pathogenetic mechanisms underlying cyst formation in the lung are still not clear and a number of hypotheses have been postulated according to the different aetiologies: ball-valve effect, ischaemic dilatation of small airways and alveoli related to infiltration and obstruction of small vessels and capillaries that supply the terminal bronchioles and connective tissue degradation by matrix metalloproteases. A wide number of lung cyst diseases have been classified into six diagnostic groups according to the aetiology: neoplastic, congenital/genetic, lymphoproliferative, infective, associated with interstitial lung diseases, and other causes. This article focuses on lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and Erdheim–Chester disease, Birt–Hogg–Dubé, follicular bronchiolitis and lymphocytic interstitial pneumonia, light-chain deposition disease and amyloidosis, congenital lung disease associated with aberrant lung development and growth, and cystic lung disease associated with neoplastic lesion. These cystic diseases are epidemiologically considered as ultra-rare conditions as they affect fewer than one individual per 50 000 or fewer than 20 individuals per million. Despite the rarity of this group of disorders, the increasing use of high-resolution computed tomography has improved the diagnostic yield, even in asymptomatic patients allowing prompt and correct therapy and management without the need for a biopsy.
