Fine needle aspiration cytology (FNAC) has been widely used in the diagnosis of lesions from various origins, especially neoplastic. The technique is simple, fast, safe, minimally invasive and inexpensive, which allows through the evaluation of cell morphology to establish prognosis, delineate surgical margins, monitor lesion growth, validate indication euthanasia during surgery and monitor chemotherapy protocols. Diagnosis of canine transmissible venereal tumor (TVT) can be accomplished with ease and precision, even to be rated, according to the degree of aggressiveness. The study objective was to demonstrate the effectiveness of the examination in the diagnosis of TVT plasmacytoid type. An eight-month dog presented to the veterinary hospital (HV), faculty of veterinary medicine and animal science, FMVZ, UNESP-Univ Estadual Paulista with clinical suspicion of cutaneous lymphoma. By presenting multiple nodular lesions, FNAC was performed to cytological diagnosis. The tissue showed cells consistent with TVT. The animal was treated, and a total cure was achieved. According to the literature, TVT mainly affects external genitalia of sexually active animals and its transmission is more frequent during intercourse. In addition, animals sexually immature and without contact to the street dogs, hardly have injuries by TVT. In this case, verrucous and ulcerated lesions on the vulva of its mother during pregnancy and childbirth infected the animal. Diffuse and predominant dorsal injuries occurred due to both exfoliation of breast tumor during delivery and immunosuppression of pup at birth, thus favoring an atypical transmission.

In the present study, the yeast Rhodotorula glutinis has been assessed with the aim of producing microbial lipids from glycerol under different aeration conditions. For such a purpose, experiments were carried out in shake flasks, under different conditions of agitation (150 to 250 rpm) and aeration (2.5 to 5.0 of flask volume-to-medium volume ratio). Furthermore, their influence on fermentative parameters (lipid and cell concentration, biomass yield;lipid yield;and lipid volumetric productivity) has been investigated using a 22 full factorial design. The statistical analysis has revealed a strong influence of both variables on substrate consumption, lipid accumulation, cell growth and lipid productivity. As a whole, results suggest that higher aeration levels provide greater cell and lipid concentrations, and lipid volumetric productivity. The best results (4.5 g/L of lipids and QP = 0.95 g/L⋅day) were achieved at the highest aeration (5.0 flask volume-to-medium volume ratio) and agitation (250 rpm) levels. Their fatty acid profile showed that oleic acid was produced in greater quantity (53.5%), followed by linoleic acid (18.7%), palmitic acid (6.8%) and stearic acid (9.9%). The microbial oil presented viscosity of 39.3 cP at 50°C and free fatty acid content of 1.93% ± 0.08%. These are significant results and contribute to establishing operational conditions that maximize single-cell oil production from glycerol by Rhodotorula glutinis, i.e. an alternative source as renewable raw material for lipid-based biorefineries.

Background: Standard treatment for subungual melanoma is wide local excision including digit amputation in order to obtain safety margins. Level of amputation has been discussed in order to achieve appropriate oncological results along with preservation of limb function wherein local excision of subungual melanoma in situ without amputation is an option. Methods: We report two cases of subungual melanoma in situ treated by using a conservative approach. Both cases were treated with local excision with the resected tumor defect covered with an artificial dermis, Matriderm?. One case was of a 65-year-old male with a left thumb subungual melanoma in situ and another of a 41-year-old female with the same type of melanoma in the left hallux. Full-thickness skin graft was used for reconstruction after 7 weeks from the first surgery in the latter, and in the former case re-epithelization occurred within 90 days after surgery. To date, no clinical signs of recurrence have been found, and finger/toe functions were completely preserved with a minimized scar and little graft bed sensitivity. Follow-up time is two years and ten months for the left thumb case, and one year and six months for the left hallux subungual melanoma in situ. Conclusion: We present two cases of subungual melanoma in situ treated with digit sparing surgery including excision of the periosteum followed by the use of an artificial dermal template to guarantee coverage of the tumor bed defect, providing good functional and cosmetic outcome.

Main Goals: Evaluation and comparison of short-term results of totally laparoscopic gastrectomy performed for gastric carcinoma in two groups of patients: older and younger than eighty years. Material and Methods: From 1st January 2011 to 31st October 2012, we have treated 110 patients for gastric carcinoma. 79 patients were submitted to radical gastric resection (the remainder 31 patients either presented with cardia carcinoma or were submitted to palliative treatment). In 33 cases we performed a laparoscopic gastrectomy while in the remainder 46 cases, the open approach was used. The 33 patients operated by a laparoscopic approach were the subject of this study. They were divided in two groups: Group A—patients eighty years old or older (10 cases) and Group B—patients younger than 80 years (23 cases). We evaluated and compared the short-term outcomes of both groups. Results: In all 33 cases, a gastrectomy was performed using a totally laparoscopic approach. There was no need to convert into open surgery. No patient needed to stay in the Intensive Care Unit. One patient needed a night stay in the Post Anesthetic Care Unit, due to subcutaneous emphysema (which resolved within 24 hours). There was a fatality in Group B, due to hepatic failure. The median of the operating time was 224 minutes in Group B and 199 minutes in Group A. The difference was non-significant (pvalue > 0.05). Group A patients were discharged in 6 to 10 days while those in Group B were discharged in 6 to 9 days. Conclusion: The results in this series suggest that totally laparoscopic gastrectomy is effective and safe in patients eighty years old and older, with low morbidity and mortality and short hospital stay. It compares favourably with the results of the same technique applied to younger patients. We suggest that laparoscopic approach to gastrectomy can be used in older patients, allowing them to benefit from the advantages of minimally invasive surgery.

Liver disease has recently been described as an im-portant cause of morbidity and mortality in patientsinfected with human immunodeficiency virus （HIV）.Liver test changes are useful surrogates of the burdenof liver disease. Previous studies have shown that trans-aminase elevations are frequent among these *** cause of those changes is harder to establish inHIV-patients. We present a 61-year-old caucasian male,diagnosed with HIV type 1 infection since 1998, underhighly active antiretroviral treatment （HAART）, withvirological suppression and immunological *** presented in a follow-up laboratory workup highvalues of transaminases, arthralgia at the hip joints and hepatomegaly. Liver function tests were normal. Theantibodies to hepatitis viruses were negative. However,autoimmune study and liver biopsy were compatible with autoimmune hepatitis （AIH）. The AIH is a rare di-agnosis in HIV-infected patients perhaps because the elevation of transaminases and changes in liver function tests are often associated to HAART or to other possible liver diseases, namely viral hepatitis and non-alcoholic steatohepatitis. The diagnosis may be underestimated. There are no specifc recommendations available for the treatment of HIV-associated AIH although the immuno-supression with slower tapering seems the most reason-able approach.
