Abstract:
This study was undertaken to analyze the effectiveness of cytological diagnostics of endocervical adenocarcinomas. We compared conventional liquid-based cytology, histology, immunohistochemistry, and molecular testing. A total of 25 endocervical adenocarcinomas, including endocervical adenocarcinomas in situ, were diagnosed using cytological methods over a year. Liquid-based cytology ensured better detection of glandular differentiation signs than conventional cytology. After molecular testing for human papillomavirus (HPV), we performed retrospective analysis of cytological characteristics of all endocervical adenocarcinomas (n = 15).We identified specific cellular characteristics of HPV-associated typical and mucinous adenocarcinomas. We also observed 1 case of non-HPV-related clear-cell and 1 case of non-HPV-related mesonephral adenocarcinoma.Our findings suggest that endocervical adenocarcinomas are a heterogeneous group of tumors. Endocervical adenocarcinomas accounted for 10.7 % of all primary cervical carcinomas (n = 214). Eighty percent of all endocervical adenocarcinomas were HPV-related, whereas the remaining 20 % were HPV-negative. We found no cytological differences between invasive endocervical adenocarcinomas and adenocarcinomas in situ.Mutations detected in some of the patients are an important diagnostic criterion that specifies whether the tumor is rare.

Abstract:
Objective — to analyze the diagnostic possibilities of histological examination of single necrotized focal lung lesions by determining their histological features and etiology. Materials and methods. The study was conducted as a cohort, retrospective. The group included 68 patients with solitary focal lesions of the lungs (from 1 to 3), the size of each focus did not exceed 3 cm. The size, shape and contours of the detected foci were evaluated based on the results of radiographs or tomograms. Morphological diagnostics included cytological and histological examination. The results of microbiological examination of operative material for the presence of mycobacteria and non-specific microorganisms, the results of molecular genetic analysis for the presence of tuberculosis mycobacteria must be taken into account; as well as a number of indicators of clinical-biochemical and immunological studies of biological fluids, clinical data as needed. Histological findings, preliminary and final clinical diagnoses were compared. Results and discussion. According to the results of X-ray analysis and traditional histological examination, a number of signs of solitary necrotic foci-nodules were identified and compared with the results of histochemical, microbiological and molecular genetics examination. It was established that solitary necrotic nodules (78.0 %), larger than 1 cm (81.0 %) of irregular shape predominate. In two-thirds of cases (62.0 %), a granulomatous process was observed, and namely in these cases mycobacteria were detected during microbiological examination. Also, only in cases of histological diagnosis of caseous necrosis or necrosis of mixed type, positive results of microbiological examination for the presence of MBT were obtained. Final histological conclusions with an accurate formulation of the pathological process were obtained in 88.2 %, while the etiology was established in 85.3 % of cases. The final clinical diagnoses had differences compared to the histological conclusions because they have a different formulation principle. Conclusions. A complex histological study in combination with microbiological and molecular genetic studies plays a decisive role in establishing of the etiology of solitary necrotic pulmonary foci. According to the results of our work, the dominated etiology of nodules was foci as a result of limited disturbances in the pulmonary blood circulation system (infarcts and focal thrombus, infarct pneumonia), tuberculous and fungal nature. The overall diagnostic efficiency of morphological diagnostics was 85.3 %.

Abstract:
Intestinal tuberculosis (ITB), a subset of extrapulmonary tuberculosis (EPTB), arises from Mycobacterium tuberculosis infection, primarily affecting the ileocecal region due to its lymphatic tissue richness. Representing approximately 10% of global EPTB cases, ITB is most prevalent in regions with high tuberculosis (TB) incidence. Its nonspecific symptoms—abdominal pain, diarrhea, fever, and weight loss—pose significant diagnostic challenges and frequently overlap with conditions like Crohn’s disease (CD). This diagnostic complexity is compounded by shared clinical, endoscopic, and histological features, with misdiagnosis risking inappropriate immunosuppressive therapy that exacerbates TB progression. Diagnostic tools include endoscopy with biopsy, imaging modalities (CT, MRI, ultrasound), and molecular assays like GeneXpert for rapid detection and drug resistance assessment. While histological markers such as caseating granulomas aid differentiation, advanced molecular methods enhance diagnostic precision. Emerging technologies, including next-generation sequencing, CRISPR-based diagnostics, and artificial intelligence in imaging, show promise in addressing diagnostic gaps. However, resource-limited settings face significant barriers, relying on less sensitive conventional methods. Integrated approaches combining clinical, histopathological, and molecular evaluations are essential for accurate diagnosis and effective management. Strengthening healthcare infrastructure, expanding access to advanced diagnostics, and leveraging innovative technologies are critical for reducing ITB-related morbidity and mortality. Keywords: Intestinal tuberculosis, Diagnostic challenges, Molecular diagnostics, Artificial intelligence, GeneXpert.

Abstract:
Colorectal and anal cancers (CRACs) are increasingly reported in sub-Saharan Africa due to rising life expectancy, dietary shifts, and improved diagnostics. This study presents a 10-year review of CRACs in Makurdi, North Central Nigeria, analysing demographic, anatomical, and histological patterns. A retrospective review was conducted of histologically confirmed CRAC cases from January 1, 2016, to December 31, 2024. Data on age, sex, anatomical site, and histological subtype were analysed using descriptive statistics. We had a total of 2341 cancers, 129 (5.5%) of which were CRACs. Males constituted 56.6% (M: F ratio 1.3:1), with a peak age incidence between 51–60 years (27%). Rectum (27%) and anus (17%) were the most common sites. Adenocarcinoma (64%) was the most prevalent histological type, followed by mucinous adenocarcinoma (16%). Notably, 19.4% of cases were recorded in patients under the age of 40. CRACs represent a burgeoning oncological issue in Makurdi, characterised by a rising incidence among younger patients and a prevalence of aggressive histological variants. Enhancing diagnostic infrastructure and implementing population-based screening programs are crucial to mitigate the increasing burden in Nigeria and sub-Saharan Africa.

Abstract:
Under conditions of egg and poultry farming noninfectious diseases are widespread and cause significant economic damage. These diseases can be caused by a variety of etiological factors: the deficiency of the necessary chemical elements, substances or their combination, excessive amount of certain classes of organic substances in feed. Diseases of complex etiology are also recorded, which arise from a combination of unfavorable factors and anatomical and physiological properties of individual bird crosses. Under the influence of unfavorable factors in various organ systems, pathological processes of various nature (dystrophic, necrotic, inflammatory) arise. In this case, the symptoms and pathological changes can be either similar or poorly visible macroscopically. In this regard, the results of histological examination of organs and tissues play an important role in making a presumptive diagnosis. The article introduces the original results of researches on pathomorphological diagnosis of the most widespread diseases in industrial poultry farming of noninfectious etiology: chronic feed borne toxicoses (including mycotoxicoses), hypovitaminosis A, hyposelenosis, amyloidosis, necrosis of the femoral head. The results of examination of spontaneous material stuff. The findings are formulated in the form of histological diagnoses. The attention is focused on the main (pathognomonical) signs of a great value for differential diagnostics of this group of diseases. Various variants of pathomorphological course of the diseases running both in a classical way, and in the form of a pathomorphosis (the variated pathoanatomical and histological lesions against application of vaccines and antibiotics) are considered.

Abstract:
Aim. Chronic gastritis was assessed serologically, endoscopically and histologically to identify correlations between these methods.Methods. Subjects comprised 319 patients who had provided informed consent. Serological assessment of chronic gastritis was based on the pepsinogen test method. Endoscopic gastritis and histological gastritis were assessed and scored according to the Kimura-Takemoto classification system and the updated Sydney classification system respectively, and correlations between these three methods were studied.Results. Pepsinogen I/II ratio showed a significant correlation to the extent of mononuclear cell infiltration of the gastric corpus. When histological gastritis was divided, on the basis of the distribution of mononuclear cell infiltration, into gastritis limited to the antrum and corpus gastritis, these types were distinguished with high accuracy using a pepsinogen I/II ratio of 3 as the cutoff. A good correlation was also seen between pepsinogen I/II ratio and development of atrophy in endoscopic gastritis, where groups with and without advanced atrophy were also distinguished with high accuracy using a cutoff value of 3.Conclusion. Significant correlations exist between serum pepsinogen levels, endoscopic gastritis, and histological gastritis. Pepsinogen I/II ratio allows prediction of the existence of endoscopic gastritis and histological gastritis, or the extent of their development, with high accuracy.

Abstract:
Myeloproliferative neoplasms (MPN), Essential Thrombocythemia (ET), Polycythemia Vera (PV) and primary myelofibrosis (PMF), are clonal disorders of the hematopoietic stem cell. In the recent years, somatic mutations of JAK2, CALR and MPL genes have been found in these diseases. However, these mutations do not allow the discrimination between the different diseases, being present in more than one form. World Health Organization (WHO) criteria, in fact, request in addition to the molecular study, a complete bone marrow histological evaluation. Pediatric ET is a rare disorder with an incidence about 60 times lower than the adult form albeit with similar blood finds. In children with ET, the incidence of JAK2V617F and CALR mutations is significantly lower than in adults, while hereditary cases characterized by MPL mutations are relatively more common. So far the histological evaluation of the bone marrow has not been exhaustively explored in this setting of patients. The aim of the present study was to evaluate the adequacy of current WHO criteria in pediatric ET exploring both the incidence of driver mutations and bone marrow features in a large cohort of children with a clinical diagnosis of ET. Our study was built in two steps: (i) a biomolecular study of a pediatric population with a clinical diagnosis of ET performed by Italian pediatricians, expert in hematological disorders and (ii) a histological evaluation strictly adherent to WHO criteria of BM features of a sub group of these children. Firstly, biomolecular studies of 89 children with a clinical diagnosis of ET, all having a sustained increase in platelet count (>450 x10^9/L) with no demonstrable reactive or secondary cause and no familial history of MPN or thrombocytosis, were evaluated to our central laboratory. In the second phase of our work we collected naïve bone marrow (BM) biopsies of 20 children with a clinical diagnosis of ET (PedET) and, as controls, BM of 6 children (PedST) with reactive/secondary thrombocytosis, 18 children (Norm) with a normal BM histology and 36 adults (AdsET) with WHO-diagnosed ET. All BM biopsies were reviewed by two MPN’s expert pathologists, blinded to the cause of each child’s thrombocytosis. In the biomolecular study we found that 23 patients (25,8%) had a clonal disease. The JAK2V617F mutation was identified in 14 children, 1 child had the MPLW515L mutation, and 6 had CALR mutations. The HUMARA monoclonal X-chromosome inactivation pattern was demonstrate in 6 patients (two with JAK2V617F and two with CALR mutations). The other 66 patients (74,2%) had persistent thrombocytosis with no clonality. There were no clinical or hematological differences between the clonal and non-clonal patients. From the histological point of view, while cellularity was increased in all pediatric cases compared to adults (p<0.001), megakaryocytes (MK) density was higher in PedET (37.5 MK/mm2) than in PedST (9.2 MK/mm2) (p<0.001). Moreover, MK clusters (100%) and BM fibrosis (30%) were observed only in PedET but not in PedST and in Norm. The BM histology was similar in PedET and AdsET. On a whole, BM histology confirmed the diagnosis of ET in 15 children, suggested a PV in 1 child, a PMF in 3 (1 grade 1 and 2 grade 0) and secondary thrombocytosis in one. Our study shows that children with ET are mostly non-clonal, however, the relative proportion of ET-specific mutations in the clonal children was much the same as in adults. Histological WHO criteria are able to identify ET, PMF and PV and distinguish ST from primary thrombocytosis, also in pediatric population. Therefore, WHO criteria seem suitable in all age groups, making both complete biomolecular evaluation and BM assessment mandatory in children with suspected ET.<br>Le Neoplasie Mieloproliferative (MPN), sono disordini clonali della cellula staminale emopoietica, caratterizzate dalla proliferazione di una o più linee mieloidi e sono Trombocitemia Essenziale (ET), Policitemia Vera (PV) e Mielofibrosi Idiopatica (PMF). I criteri diagnostici per le MPN dell’adulto si sono evoluti nel tempo di pari passo con l’acquisizione di nuove conoscenze clinico-laboratoristiche e biomolecolari di tali patologie. Negli ultimi anni sono state descritte mutazioni somatiche a carico dei geni JAK2, CALR e MPL, tuttavia queste mutazioni non consentono una distinzione accurata in quanto presenti in più di una MPN. Nei più recenti criteri diagnostici WHO, di conseguenza, accanto allo studio biomolecolare, è necessaria una completa valutazione della biopsia osteo-midollare (BOM). La ET pediatrica è una malattia rara con un’incidenza stimata di circa 60 volte inferiore alla forma dell’adulto. L’incidenza delle mutazioni di JAK2 e di CALR è significativamente inferiore nei bambini con ET rispetto agli adulti, mentre sono relativamente più numerosi i casi ereditari caratterizzati da mutazioni di MPL. Ad oggi in questi pazienti non è stata ancora esplorata esaustivamente la rilevanza della valutazione istologica del midollo. Lo scopo del nostro studio è stato quello di verificare l’adeguatezza dei criteri WHO nella popolazione pediatrica esplorando sia l'incidenza delle mutazioni principali che le caratteristiche della BOM in un'ampia casistica di bambini con diagnosi clinica di ET. Il nostro lavoro è stato costruito in due momenti: (i) uno studio biomolecolare in bambini con diagnosi clinica di ET fatta da Pediatri Italiani esperti in disordini ematologici e (ii) una valutazione istologica della BOM in un sottogruppo di questi bambini, applicando rigorosamente i criteri WHO. Nella prima parte dello studio abbiamo valutato 89 bambini con diagnosi clinica di ET con un incremento prolungato della conta piastrinica (>450 x10^9/L) in assenza di cause secondarie o reattive e senza familiarità per MPN o trombocitosi. I campioni stati sono stati centralizzati presso il nostro laboratorio per lo studio biomolecolare completo. Nella seconda fase, abbiamo collezionato le BOM di 20 bambini con diagnosi clinica di ET (PedET) e, come controlli, di 6 bambini con trombocitosi reattiva (PedST), 18 bambini (Norm) con istologia midollare nella norma e 36 adulti con diagnosi di ET in accordo con in criteri WHO (AdsET). Tutte le BOM sono state rilette in cieco da due patologi esperti in MPN. Nello studio biomolecolare in 23 pazienti (25,8%) è stata dimostrata la presenza di un marker di clonalità: 14 bambini erano positivi per la mutazione JAK2V617F, 1 bambino aveva la mutazione MPLW515L e 6 avevano mutazioni di CALR. Inoltre, sei pazienti sono risultate clonali allo studio dell’inattivazione del cromosoma X (due portatrici anche la mutazione JAK2V617F e due con mutazioni di CALR). Gli altri 66 pazienti (74,2%) presentavano una trombocitosi persistente senza evidenza di clonalità. Non sono state dimostrate differenze clinico-ematologiche tra i pazienti clonali e non clonali. Dal punto di vista istologico, la cellularità è risultata più alta in tutti i casi pediatrici rispetto agli adulti (p <0.001), mentre la densità megacariocitaria (MK) è risultata più alta nei PedET (37,5 MK/mm2) rispetto a PedST (9.2 MK/mm2) (p <0,001). Inoltre, i cluster di MK (100%) e la fibrosi midollare (30%) sono stati osservati solo in PedET, essendo sostanzialmente assenti sia in PedST che Norm. L’istologia della BOM è risultata pressoché sovrapponibile in PedET e AdsET. Tra i bambini con PedET, l’istologia della BOM ha confermato in 15 casi la diagnosi di ET, in 1 caso è risultata suggestiva per PV, in 3 casi per PMF (1 grado 1 e 2 grado 0) ed in un caso per trombocitosi secondaria. Il nostro studio conferma che, sebbene la maggior parte dei bambini non presenti un marker di clonalità, le mutazioni classiche delle MPN sono presenti anche nella ET pediatrica con una proporzione simile a quella delle forme dell’adulto. I criteri istologici WHO sono in grado, anche nella popolazione pediatrica, di identificare ET, PV e PMF e di distinguere forme primitive e secondarie di trombocitosi. In conclusione, i criteri WHO sembrano adeguati per tutte le fasce d’età. Ciò impone una completa valutazione biomolecolare ed istologica anche nei bambini con sospetta ET.

This was a clinical trial randomized study, which included women with CIN 2, attending the outpatient service of Cervical Pathology of Maternity Hospital Leonor Mendes de Barros, State Health Department, São Paulo, SP, in the period from october 2002 to january 2005. The calculated sample size was 90 women. Women were randomized to two groups of 45 patients each, one of then to be expectant follow-up and one to LLETZ. This report includes the partial results of 70 cases (40 expectant follow-up and 30 LLETZ), with focus in the group of the expectant follow-up. The inclusion criteria were women with biopsy-confirmed CIN 2, regardless of the cytologic diagnosis. The exclusion criteria were cytological diagnosis of carcinoma, HIV infection, imunossupression, previous hysterectomy and previous treatment for cervical intraepithelial neoplasia. Total regression was observed in 45% of cases, partial regression in 34% and persistence in 8%. The results showed progression to CIN 3 in 13% of cases and no progression to squamous carcinoma was observed. The mean age of women with regression was 30.6 years and for those with progression or persistence it was 38.1 years.The rate of underdiagnose for CIN 3 was 37% when only colposcopy was used. Concluded It was spontaneous regression of CIN 2, and the expectant follow-up could be used.

Além disso, a interpretação desse exame é observador-dependente e, de modo geral, há baixa concordância entre os observadores. OBJETIVO: Avaliar se há critérios morfológicos presentes na CO anormal que sejam preditivos do diagnóstico histológico de neoplasia intra-epitelial cervical. MÉTODO: Foram selecionados os laudos dos exames anatomopatológicos de 282 mulheres atendidas no Ambulatório de Patologia do Trato Genital Inferior do Centro de Atenção Integral à Saúde da Mulher da Universidade Estadual de Campinas, no período de outubro de 2001 a janeiro de 2004, encaminhadas por CO anormal. Foram constituídos quatro grupos, de acordo com o exame histológico final. O grupo 1 foi constituído por 74 mulheres sem neoplasia, o grupo 2 por 69 mulheres com NIC 1, o grupo 3 por 62 mulheres com NIC 2 e o grupo 4 por 77 mulheres com NIC 3. A associação dos critérios morfológicos com o diagnóstico histológico foi avaliada através de odds ratio. A análise da interação dos critérios morfológicos com a predição do diagnóstico histológico foi feita através de modelos de regressão logística múltipla. Todas as análises foram realizadas com intervalo de confiança igual a 95% (IC 95%). Para construir uma estrutura preditiva entre os critérios morfológicos e o diagnóstico final foi utilizada a Chi-square Automatic Interative Detection (CHAID). RESULTADOS: A média de idade das mulheres foi de 32,3 anos. Os critérios citomorfológicos independentemente associados com o diagnóstico histológico de NIC 1, em relação aos casos sem neoplasia, foram distribuição irregular da cromatina (OR 11,2 IC 95% 2,32 a 54,08), aumento da relação núcleo-citoplasmática (RNC) (OR 5,8 IC 95% 1,5 a 23,0) e espessamento citoplasmático periférico (OR 3,4 IC 95% 1,4 a 8,4). O critério citomorfológico independentemente associado com o diagnóstico histológico de NIC 2, em relação ao NIC 1, foi a atipia em célula metaplásica madura (OR 5,2 IC 95% 2,4 a 11,3). Os critérios citomorfológicos independentemente associados com o diagnóstico histológico de NIC 3, em relação ao NIC 2, foram membrana nuclear irregular (OR 3,8 IC 95% 1,2 a 11,6) e membrana nuclear espessa (OR 4,9 IC 95% 2,0 a 12,2). A presença de membrana nuclear irregular (OR 4,72 IC 95% 2,1 a 13,0) e o aumento do volume das células metaplásicas (OR 2,6 IC 95% 1,2 a 5,5) distinguiram os casos agrupados de NIC 2 e 3 dos NIC 1. Utilizando a técnica de CHAID, a variável independente que apresentou maior valor preditivo para NIC 3 foi o aumento acentuado da RNC (77,2%). Quando considerados os diagnósticos de NIC 2 e NIC 3, e estudada a anisocariose junto com o acentuado aumento da RNC, o valor preditivo para estes diagnósticos foi de 98,3%. Quando o aumento foi discreto ou moderado, o segundo critério com maior poder discriminador para NIC 3 foi a atipia em célula metaplásica. Não foram encontrados critérios morfológicos únicos para a discriminação dos diagnósticos de NIC 1 ou NIC 2. CONCLUSÕES: O aumento da RNC é o critério morfológico que mais pode predizer e discriminar os graus de neoplasia intra-epitelial cervical. Secundariamente, foram identificados a anisocariose e as células metaplásicas alteradas<br>Abstract: INTRODUCTION: The poor cito-histologic correlation is an inherent flaw of Pap smear. Moreover, Pap results are dependent on the observer opinion and interobserver concordance is generally low. OBJECTIVE: to evaluate which Pap smear morphologic criteria can predict the histological diagnosis of cervical intraepithelial neoplasia. METHODS: The histological results of 282 women referred to Diseases of Genital Inferior Ambulatory of CAISM due to abnormal Pap tests, between October 2001 and January 2004, were compiled. Patients were allocated to four distinct groups according to their pathological diagnosis. Group 1 comprised 74 women with normal/no neoplasia histological diagnosis, Group 2 consisted of 69 women with CIN1, Group 3 was formed by 62 women with CIN 2 and Group 4 of 77 women with CIN 3. The associations of morphologic criteria with histological results was assessed through the odds ratios and the interaction between morphologic criteria and pathological findings was rendered by logistic multiple regression. The Chi-square Automatic Interative Detection (CHAID) was used to construct a predictive structure of morphological criteria and histological diagnosis. All calculations were performed within 95% confidence intervals (95% CI). RESULTS: Patients¿ mean age was 32.3 years old. Cytomorphologic criteria that were independently associated with CIN 1 were: irregular chromatin distribution (OR 11,2 95% CI 2,32 a 54,08), increased nuclear/cytoplasmic ratio (NCR) (OR 5,8 95% CI 1,5 a 23,0), peripheral rim of thickened cytoplasm (OR.3,4 95% CI 1,4 A 8,4). The cytomorphologic criterium of cellular alteration in mature metaplastic cell differentiated between CIN 2 and CIN 1(OR 5,2 95% CI 2,4 a 11,3) and irregular nuclear membrane (OR 3,8 95% CI 1,2 a 11,6) and thickened nuclear membrane(OR 4,9 95% CI 2,0 a 12,2) allowed the distinction between CIN 3 and CIN 2. The presence of irregular nuclear membrane (OR 4,72 95% CI 2,1 a 13,0) and increased volume of metaplasic cells (OR 2,6 95% CI 1,2 a 5,5) distinguished between the grouped CIN 3/CIN 2 and CIN 1. The CHAID technique ascertained a predicted value of 77.2% to severely increased NCR for the diagnosis of CIN 3, while the association of increased nuclear/cytoplasmic ratio and anisokaryosis attained a predictive value of 98.3% for CIN 3. When only mild or moderate increase in nuclear/cytoplasmic ratio was present, only cellular alteration in metaplastic cell auxiliated in the diagnosis of CIN 3. There were no stand-alone cytomorphologic criteria associated with the histological diagnosis of CIN 1 or CIN 2. ONCLUSIONS: The increased NCR is the cytomorphological criteria that most can predict and discriminate the grades of CIN. Secondly, anisokaryosis and alteration in metaplastic cells were identified.<br>Mestrado<br>Tocoginecologia<br>Mestre em Tocoginecologia

Abstract:
It is reported that the echo intensity of B-mode ultrasound images increases when human elbow flexors are damaged by eccentric exercise. However, it is unknown what causes the increase in echo intensity, and its relationship to histological changes is unexplored. This study tests the hypothesis that infiltration of inflammatory cells in damaged muscle fibres causes an increase in the echo intensity of B-mode ultrasound images. The study is carried out by injecting bupivacaine hydrochloride (BPVC), which is known to result in infiltration of mononuclear cells, into rat hind limb muscles. This study was approved by the Institutional Animal Research Ethics Committee. BPVC (0.5 % of 0.5 ml) or saline (0.9 % NaCl of 0.5 ml) was injected to the tibialis anterior muscle (TA) of 14-19 wk male Wistar rats (n=12). Ultrasound images were taken from the muscles before, 0, 2, 4, 6, 9, 12, 24, 48, 72, 120, 168, and 336 hours after the injections using a 7.5 MHz probe connected to an Image Point HX® (HP, USA). The images were analysed by an Image J (NIH, USA) to assess the changes in echo intensity of a region of interest, and changes in the intensity were compared between BPVC and controlled conditions. In the subsequent study, the rats (n= 16) were sacrificed before and 0, 2, 6, 12, 24, 48, and 168 hours after BPVC or saline injection into the TA after assessing changes in the echo intensity up to the time of sacrifice in the same time course of the first study. "Histological changes in the muscle after the injection were observed and compared with the ultrasound images. Changes in the echo intensity in the TA after BPVC injection were compared between the control (non and saline injection) and injected limbs by a two-way analysis of variance with repeated measures. The echo intensity did not change significantly in muscles that did not receive an injection. BPVC injection induced greater (P

AbstractA plethora of pathologies occurs in the skeletal and soft tissues of the oro-facial region that are reactive. These arise as a result of chronic low-grade inflammation, trauma, hormonal influence and other causes. Varied types of clinical, radiological and histological presentations are often associated with these lesions that pose a diagnostic dilemma to the clinician. This chapter describes in detail the common reactive lesions of the maxillofacial region with an emphasis on correlating the clinical and investigational findings to arrive at the correct diagnosis and provide appropriate treatment.

Abstract:
AbstractFibro-osseous lesions have posed a diagnostic dilemma since the beginning when the first case was reported in the late nineteenth century. Since then, various lesions are included in this group, yet the understanding of the lesions remains obscure for the clinician/surgeon. The main reason for this is their histological resemblance with one another, where they all show varying degrees of healthy bone replaced by fibrous tissue and some amount of bone/cementum-like tissue intermingled in between. This chapter is written with the aim of simplifying these groups of bony lesions for its readers and highlighting the key idea of interdisciplinary approach in the management of these lesions where the oral pathologist along with radiologist and clinician plays a pivotal role in differentially diagnosing these lesions, for the maxillofacial surgeon to choose and perform her/his duty of managing them, rightfully, for their patients. The spectrum of these lesions has seen several changes during the course of history yet there is still ample scope for ambiguity in identification and classification of the lesions, hence the authors have chosen few most commonly encountered lesions in the Indian subcontinent, for the description and discussion.

Abstract:
AbstractPrimary liver cancer is the fourth leading cause of cancer death around the world. Histologically, it can be divided into two major groups, hepatocellular carcinoma (75% of all liver cancer) and intrahepatic cholangiocarcinoma (15% of all liver cancer) [1, 2]. Primary liver cancer usually happens in liver disease or cirrhosis patients [1], and the risk factors for developing HCC depend on the etiology [3] and the country of provenance [1]. There is an urgent need for an accurate diagnostic test given the high proportion of false positives and false negatives for alpha-fetoprotein (AFP), a common HCC biomarker [4]. Due to often being diagnosed in advanced stages, HCCrelated deaths per year have doubled since 1999 [3]. With the use of metabolomics technologies [5], the aberrant metabolism characteristics of cancer tissues can be discovered and exploited for the new biomarkers and new therapies to treat HCC [6, 7].

Abstract:
The histopathological diagnosis of malignant melanoma remains the gold standard to allow the patient to access the entire process of the diagnostic-therapeutic-assistance path. Despite the continuous search for markers that can assist in the diagnostic process, there are cases that remain complex to diagnose, and the presence of different criteria among dermatopathologists further complicates the issue. This section will focus on the state of the art of dermatopathological diagnostics of melanoma, starting from the morphological bases up to the latest acquisitions of immunohistochemistry for diagnostic purposes, and molecular biology for therapeutic purposes. Furthermore, we will focus on particularly “challenging” MM histotypes and on what are the current guidelines for a correct diagnosis.

Abstract:
The introduction of a histological method into practice of species diagnostics of trematodes of the suborder Paramphistomata Skrjabin et Schulz, 1937, contributed to regular reports on the discovery of new trematode species in the family Paramphistomidae Fischoeder, 1901. At the same time, several new species were described based on identification of specific histological morphological characteristics which in fact turned out to be artifacts in subsequent detailed analysis. Based on this argument, paramphistomid species described in domestic literature sources, namely, Cotylophoron skrjabini, Cotylophoron vigisi, Ceylonocotyle petrowi, Liorchis hiberniae and Liorchis scotiae are considered as invalid. The cause of morphological artifacts on histological sections of paramphistomids are firstly non–standardized or incorrect primary treatment with fixing chemical agents of parasite isolates detected during necropsy in definitive hosts; secondly, errors in the implementation of general histological technique elements which in the applied approach are critically important and require the development of methodologic modernization adapted to work with biological objects with morphological traits; thirdly, incorrect subjective perception of histological artifacts, their false acceptance as distinctive species characters that have diagnostic value in taxonomy of the family representatives. It is necessary to develop optimized methodological techniques adapted to the applied purpose of teaching methods based on general histological technology elements the implementation of which will help to avoid morphological artifacts on histological sections of paramphistomids.

Abstract:
Review question / Objective: The purpose of this systematic review was to systematically review the clinical studies regarding miRNAs as diagnostic biomarkers for inflammatory bowel disease and assess the overall diagnostic accuracy of miRNAs. Condition being studied: The symptoms of inflammatory bowel disease (IBD) are highly variable. The diagnosis of IBD must be made through medical history, physical, laboratory, radiologic, endoscopic, and histological examinations. However, these diagnostic techniques are not specific and sometimes even equivocal. Therefore, reliable biomarkers are urgently needed in the diagnosis of IBD. Several clinical and preclinical researches have shown that dysregulated microRNAs (miRNAs) play a crucial role in IBD development. miRNAs, as single-stranded noncoding RNAs that contain 22-24 nucleotides, can post-transcriptionally regulate gene expression by blocking mRNA translation or degrading target mRNAs. miRNAs are widely involved in physiological and pathological cellular processes, such as differentiation, proliferation and apoptosis. Besides, they are stable, noninvasive, and resistant to degradation by ribonucleases, making them valuable targets in the diagnosis, monitoring, prognosis, and treatment of diseases. To date, inconsistent results have been found about miRNA expression profiling in the patients with IBD. Moreover, the diagnostic accuracy of miRNAs for IBD has not been reported in any meta-analysis.

Lifshitz, Guy, Rotem Franko, Nitzan Goldberg, et al. Can Conservative Management of Simple Acute Appendicitis Miss a Diagnosis of Appendiceal Neoplasms? A Histological Evaluation of 686 Appendectomies of Simple Appendicitis. International Journal of Surgery, 2024. http://dx.doi.org/10.60122/j.ijs.2024.20.02.

Abstract:
Background: Acute appendicitis is one of the most common surgical disease with an estimated lifetime risk of about 6-8%. Non-operative management of appendicitis is gaining popularity worldwide. Appendiceal tumors are rare and confirmed by histopathological examination in 0.5-2.5% of all appendectomies. The risk of missing an appendiceal tumor with a non-operative treatment is not well established. The aim of this study was to assess the incidence of appendiceal neoplasm in patients presented with simple non-perforated appendicitis. Materials and Methods: A retrospective study of all patients, that underwent an appendectomy from January 2018 to June 2020 in a single academic center. The histopathological reports were reviewed for appendiceal tumor. The patients’ and disease characteristics were recorded. Final analysis included only patients with simple acute appendicitis. Results: 686 patients that underwent an emergent appendectomy for a simple acute appendicitis, nine patients (1.41%) were found to have an appendiceal neoplasm on final pathology. The preoperative imaging study did not reveal any suspicious findings for appendiceal neoplasm. Neoplasms revealed by histopathological examination include three neuroendocrine tumor (NET), four low-grade mucinous neoplasm and two adenocarcinomas. The mean age for appendiceal NET was 25.33 ± 4.72, for mucinous neoplasm 48.75 ± 29.22 and 62 ± 12.72 for adenocarcinoma. Logistic regression demonstrated a significant difference in appendiceal diameter and white blood cell count between the neoplasm and acute appendicitis group. Conclusion: Although appendiceal neoplasm following an appendectomy for simple acute appendicitis is not common, it is a concern that need to be addressed. Despite the wide use of imaging study for the diagnosis, it does not provide diagnostic indication for the existence of an appendiceal neoplasm in our cases. The risk of an appendiceal neoplasm, albeit low, should be taken into consideration in the management of adult patients with acute appendicitis before a decision to embark on a non-operative therapy.

Abstract:
Within the project "Pathogenic Streptococcus in Tilapia", gram positive cocci pathogens of fish in Israel and in the United States were characterized. We showed that Streptococcus shiloi, the name for an agent causing septicemic infection in fish, is a junior synonym of Streptococcus iniae and that Enterococcus seriolicida is a junior synonym of Lactococcus garvieae, a causative agent of septicemia and meningo-encephalitis in fish. Molecular epidemiology studies on these two pathogens, based on 16S rDNA sequences and ribotyping showed that although each country had specific clones, S. iniae originated probably from the U.S. and L. garvieae from Japan. PCR assays were developed for both pathogens and applied to clinical samples. S. agalactiael S. difficile was also recognized for the first time in the U.S. in tilapia. Our histopathological studies explained the noted paradox (abundant in vitro growth often accompanied by scant to small numbers of organisms within the meninges in histologic sections of brain) in diagnostic of fish streptococcus. The greatest concentration of cocci were consistently observed within macrophages infiltrating the extrameningeal fibroadipose tissue surrounding the brain within the calvarium. These results also suggests that the primary route of meningeal infection may be extension from the extrameningeal connective tissue rather than meningeal vascular emigration of cocci-containing macrophages. Our work has resulted in a cognizance of streptococcus as fish pathogen which goes beyond the pathology observed in tilapia and is already extended to many aquaculture fish species in Israel and in the United States. Finally, our data suggest that vaccines (bivalent or trivalent) could be developed to prevent most of the damages caused by streptococcus in aquaculture.
