Congenital deformity of the paw in a captive tiger: case report

Background: The aim of this report was to describe the clinical signs, diagnostic approach, treatment and outcome in the case of a tiger with a deformity of the paw.Case presentation: A 1.5-year-old tiger (Panthera tigris) was presented with lameness of the left thoracic limb. A deformity involving the first and second metacarpal bones, and a soft tissue separation between the second and third metacarpal bones of the left front paw were observed. The second digit constantly struck the ground during locomotion. Based on the physical and radiographic evaluations, a diagnosis of ectrodactyly was made. A soft tissue reconstruction of the cleft with excision of both the second digit and distal portion of the second metacarpal bone was performed. Marked improvement of the locomotion was observed after surgical treatment, although the tiger showed a low degree of lameness probably associated with the discrepancy in length between the thoracic limbs.Conclusion: This report shows a rare deformity in an exotic feline that it is compatible to ectrodactyly. Reconstructive surgery of the cleft resulted in significant improvement of limb function.

Estudo da perda da tensao do enxerto de tendão calcâneo bovino

Lesion of the anterior cruciate ligament (ACL) in the knee is a problem that affects animals as well as humans and may evolve with joint instability that is often symptomatic and incapacitating. The main option for ligament substitution is the autologous tendon graft. The graft undergoes tensioning during ACL reconstructive surgery to reestablish the normal laxity of the ACL- deficient knee. Although graft tensioning plays a fundamental role in postoperative clinical evolution, ideal tensioning levels have not been established in the literature. Therefore, graft elongation that may occur over time is still one of the main reasons for ligament reconstruction failure. In this study, ten bovine calcaneus tendons underwent two successive assays of physiological tensioning for a maximum deformation of 2.5% of the initial tendon length, maintained for 600s with force (N) values recorded at zero time (initial), 300s and 600s. At the end of the first assay, the tendon returned to its initial length and was maintained at rest for 300s and then the next tensioning assay was initiated, repeating the previous procedure. Statistical analysis revealed that tendon elongation is more pronounced during the initial 300s, reflecting a more accentuated decline in the tension values of the graft. Therefore, 300s after tensioning and fixing the graft, the surgeon can assess with more precision if the tensioning level was adequate.

Implantação de biomembrana de colágeno tratada em solução alcalina ou conservada em glicerina a 98% na parede abdominal de equinos

The objective of this research was obtain collagen biomembranes treated in alkaline solution for 72 hours (GE) from tendineous diaphragmatic center of equines and compare its biocompatibility with membranes preserved in a glycerin solution 98% (GG) and membranes do not treated (GC). The membranes were implanted in the internal fascia of recto abdominis muscle of equines and removed, with adjacent tissues, seven, 63 and 126 days postoperative for the preparation of histological slides. The histomorphometric study revealed more intense inflammatory process to GG and CC implants and faster healing for GE implants. It was concluded that the collagen biomembranes treated in alkaline solution is more biocompatible than biomembranes preserved in 98% glycerin.

Nosectomia em felinos portadores de carcinoma espinocelular - Relato de sete casos

Squamous cell carcinoma is a keratinocytes malignant tumor, the definitive diagnosis of this disease is based on histopathology examination of the lesions. The cats nostrils is one of regions commonly affected by this neoplasm. The response to chemotherapeutic agents, cryosurgery and radiotherapy is poor and for this reason surgical resection is instituted for remove the greatest amount of tissue engaged and provide free margins, in case of nasal involvement are indicated nosectomy often needing reconstructive techniques using as advance flaps for synthesis of surgical wounds. Due to the high incidence of feline patients with this entity, this study aims to report and discuss the effectiveness of nosectomy in seven cats with the disease. It is concluded that nosectomy as a therapeutic technique effective in five of seven cats, resecting tumor margin and providing acceptable time and quality life.

Chin augmentation with conchal cartilage

Profile enhancement most frequently involves mentoplasty. For this purpose, the author performs conchal grafts to the chin. A total of 28 women aged 15 to 76 years (mean age, 38.11 ± 15.11 years) requested mentoplasty by itself or combined with rhinoplasty, rhytidoplasty, or submental lipoplasty. The conchal cartilage was harvested subperichondrally through a posterior 3-cm incision. The specimen measured 3 x 1 cm, which was sufficient to project the chin 2 to 3 mm. For 4 to 5 mm of projection, both cartilages were used. The graft was positioned under the periosteum and held with two 5-0 nylon sutures. In these cases, the conchal cartilage graft was a suitable option for chin augmentations up to 5 mm.

O desenho-estória na atenção psicológica a crianças na fase pré-cirurgica

The hospitalization process generates stress and, for a child who has already experienced a surgery can suffer from threatening, anxiety and distress. This search examines the experiences of children indicated for different craniofacial surgery which in many cases require more than esthetic or reconstructive surgery. It is quantitative and qualitative study, descriptive and comparative. The sample is intentional and it is made up of ten children, five boys and five girls in the pre-surgical Hospital for Rehabilitation of Craniofacial Anomalies HRAC-USP, Bauru-SP. As a tool for data collection, the design-themed story and data are used from subsequent survey developed by Walter Trinca. The results indicate that the design-themed story is suitable for the identification of the kid's childhood experiences in helping to deal with the stressful situation. Some of the children reveal their feelings of anxiety and fear and manifest other defenses such as denial. In all cases it identifies emotional states of concern such as anxiety and fear, or also denial of those feelings. It was concluded by the need of creating more favorable conditions in order to identify and address childhood experiences compared to surgery in a hospital environment, proposing the designthemed story technique that reveals those experiences. It emphasizes the relevance of psychological intervention in the hospital environment, considering childhood fantasies and feelings that generate or intensify emotional states of anxiety, fear and distress in pre-surgical level.

Retorno à atividade reprodutiva de touro angus após fimose traumática com obliteração parcial da luz prepucial: relato de caso

The main disturbs affecting the genital segment of bulls are balanitis, phimosis and preputial injuries, abscesses or prolapses, resulting in decreased libido or mating ability. One case of traumatic phimosis with partial obliteration of preputial lumen is reported in Aberdeen Angus bull. During anamnesis, it was reported that the animal was unable to expose the penis and presented increased penile and preputial volume of unknown etiology after being submitted to a libido test. During clinical examination, a firm preputial mass of 15 cm in diameter was observed in the middle third of the prepuce and stenosis of preputial lumen was detected approximately 17 cm from the preputial orifice. Reconstructive surgery was the chosen therapy, with amputation of the affected foreskin portion. A skin segment of about 12 cm and affected mucosal portion were removed. Postoperative therapy consisted of dressing with chlorhexidine digluconate based ointment, povidone iodine and topical insect repellent (cypermethrin and carbamyl), systemic antibiotic therapy with benzathine penicillin (30,000 IU / kg, repeated after 48 hours) and anti-inflammatory therapy with flunixin meglumine (2 , 0 mg / kg SID) for three days. After twenty days, semen was collected by massage of the accessory glands. The ejaculate volume was 3 mL, with 200x106 spermatozoa / mL, white color, "suis generis" odor, 88% of motile sperm, 64% of progressively motile sperm and 82% of rapid sperm. Thus, the chosen surgical treatment was effective to correct the pathology and reintroduce the animal into reproductive activity

The evolution of mastectomies in the oncoplastic breast surgery era

Over time, surgical techniques have advanced to the point where oncological safety and aesthetic outcomes are the pillars of contemporary breast surgery. Variations of mastectomy came up and started allowing the oncological safety and the possibility of an immediate breast reconstruction. Nowadays the association between plastic surgical techniques and mastectomy with immediate breast reconstruction is one of the best alternatives to treat breast cancer and also improved overall aesthetic outcomes and favors the achievement of contralateral breast symmetry. Oncoplastic mastectomy is a feasible term and can be routinely used.

Steatosis and hepatic markers before and shortly after bariatric surgery

Background We present new findings on liver steatosis detected in a group of 20 morbidly obese patients who were reassessed shortly after bariatric surgery (BS) by assaying hepatic markers in their serum.Methods We assayed aspartate aminotransferase (AST), alanine aminotransferase, lactate dehydrogenase, alkaline phosphatase, gamma-glutamyl transferase (gamma-GT), cholinesterase, cholesterol, total protein, and albumin, and measured the weight and the body mass index (BMI) of patients, before and one and three months after surgery.Results There were significant reductions in BMI following surgery and also falls in transaminases and gamma-GT activities three months after BS. No changes occurred in other parameters between periods, except that cholesterol was above reference values before BS and fell to normal levels three months after BS.Conclusions We suggest that before undergoing surgery, the patients suffered from slight steatosis, while after BS the reduction in AST and gamma-GT indicated that this condition was corrected within three months. Moreover, these enzymes may be useful markers for excess fat in the liver.
