Abstract:

Background. Upper airway granulomas are commonly encountered benign masses and are a result of pronounced tissue reactivity to localized respiratory mucosal trauma. The mechanism of injury to respiratory epithelium is most commonly iatrogenic and associated with intubation or indwelling tracheostomy. Case Report. A 40-year-old obese female with a history of multiple intubations, poorly controlled diabetes mellitus type II, and history of tracheal stenosis presented with sudden onset respiratory distress requiring intubation at an outside hospital. Direct laryngoscopy revealed a rapidly forming transglottic tissue mass, measuring 5.0 × 2.2 × 0.8 cm. The following case represents an unusual exception to our experience with granulomas given its rapidity of onset and migration of tissue around the endotracheal tube. Discussion. Laryngeal erythema and granulation formation are expected postintubation findings in most patients; however, the large size of granuloma tissue and rapid onset of symptoms in this case make it remarkable. Our patient had multiple risk factors for postintubation stenosis: female sex, poorly controlled diabetes, hypertension, obesity, and multiple prior intubations for periods lasting longer than forty-eight hours. Conclusion. Our case highlights a rare laryngeal finding of a large granulation tissue mass causing sudden onset airway obstruction.

Abstract:

Abstract Over-granulation or exuberant granulation tissue is a common problem encountered in the care of chronic wounds, especially that of diabetic foot ulcers. There are several potential options for the treatment of this challenging problem. Some have an immediate short term effect but may have a longer term unfavourable effect, for example, silver nitrate application and surgical excision, which may delay wound healing by reverting the wound back to the inflammatory phase of healing. Other products, such as foams and silver dressings may offer some effect in short term, but their long term effects are questionable. The more recent research supports Haelan cream and tape as an efficacious and cost effective treatment for over-granulation in a variety of wound types. The future of treating over-granulation may lie with surgical lasers, since lasers can not only remove over-granulation tissue but will also cauterise small blood vessels and are very selective, leaving healing cells alone while removing excess and unhealthy tissue. Recently Drs Lain and Carrington have demonstrated the utility of imiquimod, an immune-modulator with anti-angiogenic properties, in the treatment exuberant granulation tissue, in a patient with long standing diabetic foot ulcer, resistant to other forms of therapy. We adapted a modified version of their protocol in the management of a similar patient in our hospital and achieved a good result in lesser time than the former.

Abstract:

The study of wound healing and its treatment is extremely important in veterinary medicine due to the high frequency of wounds and the difficulty in treating wounds by second intention. Thus, the objective of this study was to evaluate the use of a nanofiber membrane made of biodegradable polymers as a method of wound treatment in dogs. This study comprised two dogs with bite wounds. Debridement and cleaning was performed followed by the application of the membrane. In one dog, the wound was in the left proximal calcaneal region with clinical signs of infection, necrotic tissue, and muscle and the gastrocnemius tendon were exposed. The wound displayed rapid formation of granulation tissue which became excessive, so it was necessary to debride several times. However, with the suspension of the use of the membrane, formation of this tissue was not observed, and the wound evolved to epithelialization and fast contraction. In the second dog, there was a deep wound on the medial aspect of the proximal right hind limb, with clinical signs of infection, with muscle exposure. Once the membrane was placed, granulation tissue formed, and the membrane was used until the level of this tissue reached the skin. The wound underwent rapid epithelialization and contraction, without developing exuberant granulation tissue. Efficient wound repair was observed and the dogs exhibited greater comfort during application and use of the membrane. More studies should be conducted in dogs focusing on the application of this membrane until the appearance of healthy granulation tissue, as continued use seems to stimulate the formation of exuberant granulation tissue.

Abstract:

Mycetoma or Maduramycosis is a localized chronic suppurative infection characterized by exuberant granulation tissue, discharging sinuses, and bone involvement later in the course of the disease. Early clinical diagnosis before the appearance of sinuses and grains (aggregates of organism surrounded by granulation tissue, which are discharged from the draining sinuses) is difficult. Delay in diagnosis may lead to amputation of the affected part. Definitive diagnosis is through biopsy and microbiological examination. However, at times diagnosis may still be difficult. The recently described “dot in circle” sign on magnetic resonance imaging (MRI) is easy to recognize and highly specific. We present a case of mycetoma foot with characteristic MRI features.

Abstract:

Wound healing in horses is particularly problematic compared to other species and limb wounds often exhibit complications such as exuberant granulation tissue, poor wound contraction and unsightly scars. In comparison, oral wounds heal without scar formation. Therefore, in vitro experiments were conducted to investigate the differences between equine oral and limb fibroblasts in terms of proliferation and their ability to contract a collagen matrix, a commonly used in vitro model of wound contraction.

Abstract:

AbstractA case of severe inflammation with an exuberant granulation lesion of the larynx that mimicked laryngeal tumour is presented. A patient who was a chronic smoker, with a history of hoarse voice underwent multiple endoscopies and biopsies, confirmed histopathologically as acute and, subsequently, as chronic inflammation. The tumour-like tissue in the larynx responded dramatically to prolonged antibiotic treatment. We emphasize the importance of histological confirmation before embarking on removal of an essential organ or part of the body which could lead to physical or emotional scarring.

Abstract:

Exuberant granulation tissue (EGT) is a frequently encountered complication during second intention healing in equine distal limb wounds. Although it is still unknown what exactly triggers the formation of this tissue, previous research has revealed a persistent inflammatory response in these wounds. In this preliminary study we examined this inflammatory response in EGT-developing wounds as well as in experimental induced wounds. Immunohistological stainings were performed to detect primary inflammatory immune cells (MAC387 staining) as well as pro-resolution immune cells (CD163 staining). Our results show a significantly higher amount of MAC387+ and CD163+ cells in the fibrotic regions of EGT compared with the 19-day-old experimental wounds. This persistent high amount of fibrosis-promoting CD163+ cells in EGT suggests that the wound healing processes in EGT-developing wounds are arrested at the level of the proliferation phase.

Abstract:

ABSTRACT This study aimed to evaluate Himatanthus drasticus latex in a mice wound healing experimental model. Animals were divided into four groups (n=7) according to the treatments: GI - saline 0.9% (control), GII - mineral oil (vehicle), GIII - H. drasticus commercial latex (HdCL) and GIV - H. drasticus mixed isolated fraction (MIF, 1 mg/mL). The treatments were applied topically once daily, 50 µL for 14 consecutive days. Macroscopic lesions were evaluated, considering parameters such as swelling, redness, granulation tissue and reepithelialization. VEGF+, CD68+ expressions and mast cells (Toluidin blue stain) were evaluated. HdCL induced higher contraction and exuberant granulation tissue (P > 0.05). HdCL showed a mild inflammatory process while MIF induced intense infiltrate inflammatory predominantly by lymphocytes, vascular congestion, bleeding and did not presented full reepithelialization. Reorganization of collagen fibers (red picrosirius stain) was observed. CD68+ expression and mast cells were presented as moderate, intense and mild in GI, GIII and GIV, respectively. Neovascularization occurred in all groups, while VEGF+ expression was intense in MIF in relation to HdCL. We concluded that HdCL presents wound healing potential, through modulation of mast cells, CD68+ and VEGF+ expressions that can be associated to triterpenes presence according MIF isolated from HdCL.

Abstract:

Sarcoidosis is a common multisystem granulomatous condition of unknown aetiology, predominantly involving the respiratory system. Tracheal stenosis has been described but we believe that we present the first case of a tracheo-oesophageal fistula secondary to chronic sarcoidosis. A 57-year-old woman with sarcoidosis, a known tracheal stricture and a Polyflex® stent in situ presented with stridor. Bronchoscopy confirmed in-stent stenosis, by exuberant granulation tissue. The stent was removed and the granulation tissue was resected accordingly. Postoperatively, the patient was noticed to have an incessant cough and video fluoroscopy raised the suspicion of a tracheo-oesophageal fistula. A repeat bronchoscopy demonstrated marked granulation tissue, accompanied by a fistulous connection with the oesophagus at the mid-lower [middle of the lower] third of the trachea. Three Polyflex® stents were sited across the entire length of the trachea. Sarcoidosis presents with varying clinical manifestations and disease progression. Tracheal involvement appears to be a rare phenomenon and usually results in stenosis. To date, there has been little or no documented literature describing the formation of a tracheo-oesophageal fistula resulting from sarcoidosis. Early reports documented the presence of sarcoidosis induced weakening in the tracheal wall, a process termed tracheal dystonia. Weaknesses are more apparent in the membranous aspect of the trachea. Despite the rare nature of such pathology, this case report highlights the need to consider the presence of a tracheo-oesophageal fistula in sarcoidosis patients presenting with repeat aspiration in the absence of an alternate pathology.

Abstract:

Background: Cutaneous lesions in horses are common, accounting for approximately 50% of all neoplasms of this species, and can cause irritability, pruritus and predispose to secondary infections. Studies have provided information of frequency of cutaneous neoplasms in horses, but few included non-neoplastic lesions. The aim of this study is to identify the frequency of cutaneous lesions in horses diagnosed in Southern Brazil, through a retrospective study and identification of the anatomic location of the lesion, the breed, gender and age of the animals affected.Materials, Methods & Results: A retrospective study on skin lesions in horses using the database of the Veterinary Pathology Laboratory located in Southern Brazil was carried out from January 2000 to February 2013. Cases were searched for and selected by diagnosis, considering age, breed, gender, location and time of occurrence. The most common lesions included sarcoid, exuberant granulation tissue, squamous cell carcinoma (SCC), pythiosis, habronemiasis, melanoma, papillomatosis and Culicoides hypersensitivity. The most affected age range for sarcoid was animals from 1 to 5 years of age and for SCC was over 15 years of age. There was a positive association between sarcoid occurrence and being female and between SCC and habronemiasis and being male. Sarcoid, exuberant granulation tissue, pythiosis and habronemiasis most frequently involved the limbs, while SCC affected the urogenital and ocular systems and melanoma affected the tail. Pythiosis, habronemiasis, Culicoides hypersensitivity and nodular collagenolytic granuloma had seasonal occurrences. Sarcoid, exuberant granulation tissue and SCC were the most commonly diagnosed lesions. Sarcoid affected mostly younger animals, while SCC commonly affected older animals. Habronemiasis and Culicoides hypersensitivity occurred mostly during the spring and summer, while pythiosis most often presented during autumn and winter.Discussion: The frequency of neoplastic lesions in the present work was similar to other studies. Among horse skin neoplasms, sarcoid is the most common, as was observed in this study. Sarcoid primarily affects young animals and most of these have an age range between one and five years, which was also noted and supported by statistical analysis. EGT is the most common non-neoplastic lesion in the skin of horses, most commonly in the limbs. The high frequency described may be related to a higher genetic predisposition or due to the employment of these horses in intensive work. SCC is the second most common skin neoplasm and often affects older horses, as it was observed. Urogenital tract and males were the most affected location and gender. Due to their ventral location, smegma may be a more likely etiology. It was observed a lower frequency of pythiosis and this may be due to the geographical location of the laboratory, where economy it is not based on livestock or rice farming, which can predispose animals to stay in stagnant water. Cutaneous habronemiasis is often diagnosed during warm months that have high biting insect activity, as observed here, where 75% of the cases occurred during the spring-summer. Differential diagnoses of nodular collagenolytic granuloma and habronemiasis was based not only on the presence of the parasite but also on the morphologic features of the lesion. Culicoides hypersensitivity is the most common and severe allergic condition in horses distributed worldwide because of the favorable weather conditions for the reproduction of the insect. In this study, 75% of the cases occurred during the spring-summer. Lesions are usually multiple, as it was observed in 50% of the cases.

Abstract:

<p>A 7 year old working mule, with the history of traumatic injury on left hind limb, was presented to TVCC within 6-7 hours of injury with open complicated skin wound. Physical and clinical examination revealed rupture of superficial and deep digital flexor tendons with relative soft tissue and skin damage. The case was diagnosed as traumatic flexor tendon rupture and posted for surgical correction by Bunnell-Mayer suturing technique. Anaesthesia was induced using Xylazine (1.1 mg/kg) and Ketamine (2.2 mg/kg) combination and maintained with thiopental sodium (500 mg) under lateral recumbency. Polyglactin-910 (#2) suture was preferred for tenorrhaphy because of higher tensile and functional strength. Post-operative immobilization was achieved by fiber-glass full limb cast. Animal showed lameness for the first post-operative week, and then slowly reduced. During the cast removal at 6<sup>th</sup> week post-operatively, there was exuberant granulation tissue formation, which was removed by using cauterization. The dressing of wound was continued with proper debridement and antibiotic till the re-establishment of damaged tissue.</p>

Abstract:

The progression of wound healing is a complicated but well-known process involving many factors, yet there are few products on the market that enhance and accelerate wound healing. This is particularly problematic in veterinary medicine where multiple species must be treated and large animals heal slower, oftentimes with complicating factors such as the development of exuberant granulation tissue. In this study a crosslinked-hyaluronic-acid (HA-) based biomaterial was used to treat wounds on multiple species: rats, dogs, and horses. The base molecule, thiolated carboxymethyl HA, was first found to increase keratinocyte proliferation in vitro. Crosslinked gels and films were then both found to enhance the rate of wound healing in rats and resulted in thicker epidermis than untreated controls. Crosslinked films were used to treat wounds on forelimbs of dogs and horses. Although wounds healed slower compared to rats, the films again enhanced wound healing compared to untreated controls, both in terms of wound closure and quality of tissue. This study indicates that these crosslinked HA-based biomaterials enhance wound healing across multiple species and therefore may prove particularly useful in veterinary medicine. Reduced wound closure times and better quality of healed tissue would decrease risk of infection and pain associated with open wounds.

Abstract:

Background: Cutaneous wounds in locomotor limbs represent one of the most frequent disorders in equine medicine. Wounds in equines are distinguished from those in other species by unique characteristics, including different healing rates among breeds, wound location and high propensity to formation of exuberant granulation tissue during the healing process. The wound healing process that cannot be sutured can be accelerated by the use of skin grafts, lowering the treatment cost.The objective of this report was to divulgate the success upon treatment of an extensive lacerated wound in the metatarsal region of a horse using autologous skin grafts.Case: A 3-year-old, female, American quarter horse weighting 450 kg was brought to veterinary hospital with lower limb injury. According to the owner’s report, the animal had one of its limbs stuck in a plain wire fence. A wound was observed in the metatarsal region during physical examination, the lesion caused an extensive skin laceration that showed the dorsal surface of the metatarsal bone and the digital extensor tendon. After injury assessment, wound debridement was carried out by surgery intervention followed by antisepsis and application of autologous plasma every two days as post-surgical care and wound preparation to receive the graft. Forty-five days after the first intervention, grafts were collected from the neck and implanted in the wound. The procedure achieved 70% of success. After approximately 75 days, transplantation was performed in other regions of the wound using the same technique. The duration of treatment at the Veterinary Hospital of the Universidade Paranaense (UNIPAR) was eight months, and then the animal returned home, where dressings were applied for two months to avoid the risk of contamination and until complete recovery.Discussion: The debridement of the wound and edges approximation were of great value in order to begin the process of wound granulation. The established therapy with scarring with gauze and use of antiseptics only in the initial stages of treatment, the frequent exchange of bandages every two days, preventing the accumulation of exudate and the use of autologous plasma favored the formation of the granulation bed and was sufficient to avoid infection and the formation of exuberant granulation tissue. Factors such as excessive movement and local infection were also attributed as responsible for the longer healing period, so the use of the spring coupled to the horseshoe decreased the joint movement, proving tobe effective in patients with severe extensor tendon lacerations. The use of the spring coupled to the horseshoe promoted a correct biomechanical alignment and no walking complication or deficiency was observed. The correct anatomical structural positioning prevents the formation of flexural deformities and fibrosis of the joint capsule. The use of micrografts wasbeneficial and simple to perform and the use of grafts contributed to a better cosmetic result. The main factor contributed to the grafting success was the use of dressing, which was regularly changed, and topical antimicrobial therapy correctly applied to avoid contamination. Based on the clinical result of this patient, it was concluded that the use of small autologous grafts can provide good recovery and healing of extensive wounds in horses when proper care with dressings and antimicrobial medication is provided after surgical interventions.Keywords: equine, surgery, graft, healing.

Abstract:

A retrospective study of equine skin diseases diagnosed in the Laboratório Regional de Diagnóstico, Faculdade de Veterinária, Universidade Federal de Pelotas was conducted between 1978 and 2013. The necropsy and biopsy protocols for horses received for diagnosis were reviewed to determine the prevalence of dermatopathies in southern Brazil. The most prevalent skin diseases in decreasing order were: sarcoid [234/710 (32.9%)], exuberant granulation tissue [81/710 (11.4%)], pythiosis [67/710 (9.4%)], squamous cell carcinoma [55/710 (7.7%)], papillomatosis [33/710 (4.6%)] and habronemiasis [30/710 (4.2%)]. Other skin lesions accounted for 25.3% of all cases studied. The Crioulo breed was the most prevalent [310/710 (43.6%)]. Horses aged between 2-5 years old [230/710 (32.3%)] were the most frequently affected. The data obtained in this study demonstrate the importance of skin diseases that affect horses in southern Brazil. The most of the dermatopathies observed in horses, although not resulting in death could cause aesthetic damage resulting in animal rejection, the inability to participate in collective sports activities and economic losses due to treatment and surgery costs

Abstract:

Abstract Objective.—To describe the histologic changes associated with preoperative fine-needle aspiration biopsies of benign parotid lesions and the features that distinguish these changes from malignant neoplasms. Materials and Methods.—Ten benign parotid lesions with a recent history of preoperative fine-needle aspiration were selected, including pleomorphic adenoma (4 cases), oncocytic adenoma (3 cases), myoepithelioma (1 case), Warthin tumor (1 case), and lymphoepithelial cyst (1 case). Results.—A spectrum of histologic alterations were observed. Alterations included squamous cell metaplasia (8 cases), infarction and necrosis (4 cases), subepithelial stromal hyalinization (3 cases), acute and chronic hemorrhage and inflammation with multinucleated giant cells (all cases), granulation tissue with subsequent fibrosis (all cases), cholesterol cleft formation (1 case), pseudoxanthomatous reaction (1 case), pseudocapsular invasion (1 case), and microcystic degeneration (2 cases). In cases with exuberant squamous metaplasia, necrosis, or subepithelial stromal hyalinization, a diagnosis of squamous cell carcinoma or low-grade mucoepidermoid carcinoma was seriously considered. Conclusions.—Knowledge of a previous fine-needle aspiration procedure and awareness of its effects on histology of the subsequent parotidectomy specimens are necessary to avoid potential misdiagnosis.

Abstract:

BACKGROUND: Wound cleansing is an important component of wound management. PURPOSE: This study was conducted to examine the effect of a wound management solution (WMS) containing hypochlorous acid (HOCl) on methicillin-resistant Staphylococcus aureus (MRSA) and healing when used in conjunction with debridement. METHODS: Nineteen (19) deep reticular dermal wounds (22 mm × 22 mm × 3 mm deep) were created on the paravertebral and thoracic areas of 3 female pigs using a specialized electrokeratome. Wounds were separated by at least 5 cm to 7 cm of unwounded skin and inoculated with MRSA. After 72 hours, all wounds were debrided with a curette and irrigated with either the WMS or sterile saline solution twice per day from day 0 to day 4. Wounds then were irrigated once a day until the completion of the study (day 11). Wound tissue specimens were taken using punch biopsy for microbiological and histological analysis on days 4, 8, and 11 post treatment. Percent of wound epithelialized, epithelial thickness (cell layers µm), white cell infiltrate (1 = absent, 2 = mild, 3 = moderate, 4 = marked, 5 = exuberant), and percent of granulation tissue formation were calculated and assessed. Microbiology and histology results were analyzed for significant differences between treatments and among assessment days using one-way analysis of variance and student t-tests. A P value ≤ .05 was considered significant. RESULTS: The WMS effected a bacterial reduction (P ≤ .05) of more than 2.74 ± 0.43 and 1.03 ± 0.22 Log CFU/g in all assessment days compared with baseline before and after debridement, respectively. Percent epithelialization was significantly different between treatments on day 8, only 78.3% and 67.8% for HOCl and saline, respectively (P ≤ .05). No significant differences between treatments were observed for epithelial thickness or granulation tissue formation. CONCLUSION: The combination of debridement and HOCl wound irrigation can significantly reduce MRSA contamination and facilitate the healing process compared to saline irrigation. Clinical studies are needed to confirm these results.

Abstract:

Pyogenic granuloma is a benign, localized mass of exuberant granulation tissue produced in response to various stimuli. It is inflammatory hyperplasia of oral cavity commonly seen on gingival area and rarely on other parts of oral cavity such as lips, tongue, palate and buccal mucosa. It is seen predominantly in 2nd to 3rd decade of life in young females. Clinically manifesting as small red erythematous exophytic lesion, it must be biopsied to rule out other serious conditions. This article aims to present three cases of extra gingival pyogenic granulomas occurring in rare sites such as buccal mucosa, anterior hard palate and alveolar mucosa of completely edentulous ridge in maxilla. Pyogenic granuloma on buccal mucosa and anterior hard palate were seen in female patients with age of 40 years and 34 years respectively and pyogenic granuloma on alveolar mucosa of edentulous ridge in maxilla was noted in 70 years old male patient. Surgical excision was performed for all the lesion and follow up of one year did not show any recurrence. Please add little description of patient + treatment + followup results.

Abstract:

Objectives: New techniques are being utilized to improve outcomes for endoscopic sinus surgery, including newer forms of packing. Platelet gel is an innovative technique that holds many advantages, including comfort, hemostasis, and growth factors that may improve wound healing. This report discusses the theoretical advantages of this packing material and describes the initial results in a cohort of patients who underwent endoscopic sinus surgery. Methods: A cohort of patients who underwent endoscopic sinus surgery were interviewed and evaluated after the placement of platelet gel. A quality of life study was also administered for further understanding. Results: None of the patients in the study had postoperative epistaxis that required additional packing, and there were no instances of synechia formation or exuberant granulation tissue. Although not statistically significant because of a small population, the quality of life scores did show improvement over the control group. Conclusions: Platelet gel used as a packing material after endoscopic sinus surgery offers efficient hemostatic properties, as well as growth factors that can advance the healing process. The quality of life of the patient may be improved by the use of platelet gel packing.

Abstract:

Limb wounds on horses are often slow to heal and are prone to developing exuberant granulation tissue (EGT) and close primarily through epithelialization, which results in a cosmetically inferior and non-durable repair. In contrast, wounds on the body heal rapidly and primarily through contraction and rarely develop EGT. Intravenous (IV) multipotent mesenchymal stromal cells (MSCs) are promising. They home and engraft to cutaneous wounds and promote healing in laboratory animals, but this has not been demonstrated in horses. Furthermore, the clinical safety of administering >1.00 × 108 allogeneic MSCs IV to a horse has not been determined. A proof-of-principle pilot project was performed with two horses that were administered 1.02 × 108 fluorescently labeled allogeneic cord blood-derived MSCs (CB-MSCs) following wound creation on the forelimb and thorax. Wounds and contralateral non-wounded skin were sequentially biopsied on days 0, 1, 2, 7, 14, and 33 and evaluated with confocal microscopy to determine presence of homing and engraftment. Results confirmed preferential homing and engraftment to wounds with persistence of CB-MSCs at 33 days following wound creation, without clinically adverse reactions to the infusion. The absence of overt adverse reactions allows further studies to determine effects of IV CB-MSCs on equine wound healing.

Abstract:

In addition to its cytoprotective effects, growth hormone-releasing peptide 6 (GHRP-6) proved to reduce liver fibrotic induration. CD36 as one of the GHRP-6 receptors appears abundantly represented in cutaneous wounds granulation tissue. The healing response in a scenario of CD36 agonistic stimulation had not been previously investigated. Excisional full-thickness wounds (6 mmØ) were created in the dorsum of Wistar rats and topically treated twice a day for 5 days. The universal model of rabbit’s ears hypertrophic scars was implemented and the animals were treated daily for 30 days. Treatments for both species were based on a CMC jelly composition containing GHRP-6 400 μg/mL. Wounds response characterization included closure dynamic, RT-PCR transcriptional profile, histology, and histomorphometric procedures. The rats experiment indicated that GHRP-6 pharmacodynamics involves attenuation of immunoinflammatory mediators, their effector cells, and the reduction of the expression of fibrotic cytokines. Importantly, in the hypertrophic scars rabbit’s model, GHRP-6 intervention dramatically reduced the onset of exuberant scars by activating PPARγ and reducing the expression of fibrogenic cytokines. GHRP-6 showed no effect on the reversion of consolidated lesions. This evidence supports the notion that CD36 is an active and pharmacologically approachable receptor to attenuate wound inflammation and accelerate its closure so as to improve wound esthetic.

Abstract:

Cutaneous habronemosis in horses is caused by larvae of the spirurid nematodes Habronema microstoma and Habronema muscae. These lesions, also known as “summer sores’’, are often severe and disfiguring. Although Habronema-caused lesions at the coronary grooves have been described, cases of hoof cracks with secondary summer sores have never been reported. The present case describes clinic-pathological and surgical features of a quarter crack case complicated by cutaneous habronemosis at the dermal layers. A 15-year-old, Andalusian stallion was referred to the Veterinary Teaching Hospital of the University of Teramo because of a mass of the hoof and a severe lameness. The clinical examination revealed an exuberant granulation tissue protruding from a full thickness vertical quarter crack. The mass was surgically removed, and subjected to histopathological, microbiological, and parasitological analyses. A copromicroscopic examination was also performed. The feces scored PCR positive for H. muscae, while the skin for both H. microstoma and H. muscae, thus confirming the primary role of Habronema in causing the hoof mass. This is the first description of a hoof wall crack complicated by summer sores, with simultaneous gastric habronemosis. This case confirms that a prompt diagnosis during fly activity is imperative for an efficacious treatment and a timely prevention of disfiguring summer sores.

Abstract:

Wound healing in horses is complicated, particularly when wounds are on the limb. The objectives of this study were to clone equine thrombospondin II (THBS2) and secreted protein acidic and cysteine-rich (SPARC) cDNAs and to compare the spatiotemporal expression of mRNAs and proteins during repair of body and limb wounds. These molecules were targeted in view of their potential biological contribution to angiogenesis, which is exacerbated during the repair of limb wounds in horses. Cloning was achieved by screening size-selected cDNA libraries previously derived from 7-day-old wounds. Expression was studied in unwounded skin and in samples from 1, 2, 3, 4, and 6 wk old wounds of the body and limb. Temporal gene expression was determined by semiquantitative RT-PCR, while protein expression was mapped immunohistochemically. The temporal pattern of expression for both genes was similar; wounding caused immediate upregulation of mRNA, which did not return to baseline by the end of the study, and overexpression was noted in body relative to limb wounds. Immunostaining for THBS2 and SPARC was induced by wounding, though no differences in stain location or intensity were detected between body and limb wounds. This study is the first to characterize equine cDNA for THBS2 and SPARC and to document mRNA expression over the different phases of repair. THBS2 and SPARC might modulate angiogenesis during wound healing in the horse, which could protect against the disproportionate fibroplasia commonly afflicting limb wounds and leading to the development of exuberant granulation tissue.

Abstract:

Laryngeal hemiplegia is one of the most common upper airway affections in horses. Laringoplasty is indicated in high-performance animals, and when the only complaint is noisy breathing, ventriculectomy and cordectomy can be performed. This study aimed to establish a minimally invasive surgical approach to ventriculocordectomy in horses, through a videoendoscopic procedure. The technique was developed in two stages, the first one was a cadaveric study and the second one was in vivo, both using two flexible endoscopes. A bilateral ventriculocordectomy was performed in two cadavers, totaling the removal of four vocal cords. In the second stage, a left unilateral ventriculocordectomy was performed in three animals with laryngeal hemiplegia. The vocal cords were pulled by one of the endoscopes with 3.2mm grasping forceps, while the second equipment was used for the resection of vocal cords with a flexible electrode adapted for monopolar electrosurgery (electrocautery). The average time for removal of the vocal cords was 23±5 minutes. In the postoperative care, moderate inflammation around the surgical wound was observed, with complete healing in 21 days in one horse and 28 days in the other two. One animal presented exuberant granulation tissue on the surgical site. Other complications due to the tested technique were not noticed; therefore, it could be a less invasive option for ventriculocordectomy in horses. The developed technique proved to be effective for ventriculocordectomy execution in horses. The main advantages of this approach were reduced surgical time, shorter healing average time, no need for daily dressings and return to normal activities in a shorter period when compared to other surgical approaches. The limitation of the technique consists of the need for two endoscopes for its accomplishment. Further studies, with more animals, are needed to improve the technique.

Abstract:

The authors describe 3 children who presented with progressively enlarging skin-covered solid masses over the shunt catheter in the neck/clavicular region. The authors reviewed the clinical, laboratory, pathological, radiographic, and follow-up data for all 3 patients and reviewed the literature on the subject. The patients had no clinical evidence of an infectious process. Surgical exploration revealed that masses were surrounding and encasing the shunt tubing to which they were strongly attached. Pathological studies of the tissues demonstrated varying degrees of exuberant chronically inflamed granulation tissues, interstitial fibrosis, and dystrophic calcification. One patient had associated thinning of the skin overlying the mass and subsequently developed ulceration. No infectious organisms were observed. The cerebrospinal fluid aspirates from the shunts did not yield any organisms. There has been no recurrence of the masses. The presence of a growing mass over the shunt tube in the neck or the chest region without clinical evidence of infection does not indicate that the mass should be treated with antibiotics and complete shunt removal. Rather, the mass can be cured by extirpation and with “bypass” new shunt tubing locally.

A 2.5-years-old, Holstein lactating dairy cow was presented to the Veterinary Health Center with severe conjunctivitis and exuberant granulation tissue formation of the left eye. Upon close examination of the eye, a 2-cm long slender-shaped nematode was found in the conjunctival sac. The nematode was examined by a veterinary parasitologist and determined to be Thelazia species. The exuberant granulation tissue was surgically removed and a total of 0.5 mL of 1% levamisole was injected subconjunctivally. Levamesole was also injected subcutaneously at a dose of 10 mg/kg of body weight and repeated after 15 days. The cow made a complete recovery within 25 days following treatment. This is the first case report of ocular thelaziasis in dairy cattle in Jordan.

Abstract:

Background: Thermal injury is one of the most common type of skin damage found in clinical care, which results in a chronic wound. The treatment of chronic wounds should be specific, because it has a greater vulnerability of the organism to the external agents input. So, the treatment can be performed with covers to keep the lesion clean and free of contamination and also promote healing. Considering the amount of products available for the treatment, as well as the scarcity of studies in the literature proving the effectiveness of hydrocolloid in dogs, the aim of this case report was to describe a third degree burn wound in the sternal region of a dog treated with this material.Case: A 2-year-old non-castraded German Spitz dog, was attended in a private veterinary clinic located in Ribeirão Preto city, São Paulo state. The animal was submitted to general anesthesia for microneedling session to treat alopecia "X", and after the procedure, it showed a burn focus due to the resting time on the thermal mattress, affecting the entire sternal region. The choice treatment was a surgical debridement followed by second intention healing. The superficial crust of the wound was removed and the debridement of almost all the tissue that was not fit for healing was continued, resulting in a wide wound, with healthy tissue and only a small portion of devitalized musculature. On the same day, the daily dressing phase with crystal sugar was started, in order to promote the debridement of the remaining devitalized tissue and enable the appearance of granulation tissue, together with the asepsis provided by the chlorhexidine ointment (0.7 g/100mL). After five days, the wound presented with ascending granulation, with no signs of contamination and minimal residue of devitalized tissue. Then, the treatment with the hydrocolloid plate was chosen, which was cut and molded to the wound to allow the debridement with crystal sugar to continue in the devitalized muscle region. At this stage of treatment, the wound region where crystal sugar was used was cleaned and given a new dressing to be changed the next day, while the rest of the wound that had the hydrocolloid plate remained unmanaged for an average of five days, in order to improve animal welfare. After six days of dressing, the wound showed significant contraction, however the growth of the granulation tissue was exuberant. Four days after the first dressing change, the contraction of the wound proceeded at an accelerated rate, as well as the proliferation of granulation tissue, and on the 15th day of treatment with the hydrocolloid plaque, the wound was already quite reduced, with the maintenance of the tissue with healthy granulation, without contamination and with signs of good evolution. On the 27th day, the wound was practically healed, leaving a small central portion of the lesion. The scar tissue that involved the burn contributed to its retraction and accelerated the reepithelialization process. Finally, after 42 days, when the treatment finished, it was possible to notice hair growth and poor visibility of scar tissue.Discussion: The application of this type of dressing in the micro-needling burn injury suggested a better healing due the increase of keratinocyte proliferation and cell proliferation, since when used in the inflammation process, it accelerated the cleaning of purulent and necrotic tissues, stimulating the repair of clean wounds leading to good results and greater patient comfort. This study demonstrated that good healing could be achieved in alternative treatment using hydrocolloid dressing. In this method, healing proved to be more effective than conventional treatment, considering wound resolution and wound healing time.
