Background: The cytology and the support of clinical symptoms, biochemistry for diagnosis of the cases of effusions are very important. Objectives: - To describe some of clinical symptoms and biochemistry of effusions. - To compare the results between cytology and biochemistry by the causes of pleural, peritoneal fluids. Material & Method: A cross-sectional study to describe all of 47 patients with pleural, peritoneal effusions examinated by cytology in the Hospital of Hue University of Medicine and Pharmacy from April 2013 to January 2014. Results: In 47 cases with effusions, pleural effusion accounting for 55.32%, following peritoneal effusions 29.79% and 14.89% with both of them. The most common symptoms in patients with pleural effusions were diminished or absent tactile fremitus, dull percussion, diminished or absent breath sounds (100%), in patients with peritoneal effusions was ascites (95.24%). 100% cases with pleural effusions, 50% cases with peritoneal effusions and 80% cases with pleural and peritoneal effusions were exudates. The percentage of malignant cells in patients with pleural effusions was 26.92%, in peritoneal effusions was 28.57%, in pleural and peritoneal effusions was 42.86%. The percentage of detecting the malignant cells in patients with suspected cancer in the first test was 57.14%, in the second was 9.53% and 33.33% undetectable. Most of cases which had malignant cells and inflammatory were exudates, all of the cases which had a few cells were transudates. Besides, 7.5% cases which had high neutrophil leukocytes were transudates. Conclusion: Cytology should be carry out adding to the clinical examinations and biochemistry tests to have an exact diagnosis, especially for the malignant ones. For the case with suspected cancer, we should repeat cytology test one more time to increase the ability to detect malignant cells.

Several research groups have explored the repositioning of human immunodeficiency virus aspartyl peptidase inhibitors (HIV-PIs) on opportunistic infections caused by bacteria, fungi and protozoa. In Trypanosoma cruzi, HIV-PIs have a high impact on parasite viability, and one of the main alterations promoted by this treatment is the imbalance in the parasite’s lipid metabolism. However, the reasons behind this phenomenon are unknown. In the present work, we observed by transmission electron microscopy (TEM) that the treatment of T. cruzi epimastigotes with the HIV-PIs lopinavir and nelfinavir induced a huge accumulation of crystalloid-shaped lipids within the reservosomes, most of them deforming these key organelles. As previously reported, those structures are characteristic of lipid inclusions formed mostly of cholesterol and cholesterol-esters. The fractionation of nontreated epimastigotes generated two distinct fractions enriched in reservosomes: one mostly composed of lipid inclusion-containing reservosomes (Fraction B1) and one where lipid inclusions were much less abundant (Fraction B2). Interestingly, the extract of Fraction B2 presented enzymatic activity related to aspartyl-type peptidases 3.5 times higher than that found in the extract obtained from Fraction B1. The cleavage of cathepsin D substrate by this class of peptidases was strongly impaired by pepstatin A, a prototypical aspartyl PI, and the HIV-PIs lopinavir and nelfinavir. In addition, both HIV-PIs also inhibited (to a lesser extent) the cruzipain activity present in reservosomes. Finally, our work provides new evidence concerning the presence and supposed participation of aspartyl peptidases in T. cruzi, even as it adds new information about the mechanisms behind the alterations promoted by lopinavir and nelfinavir in the protozoan.

Eosinophilic Gastrointestinal Disorders

Background: Despite its uncommon occurrence, eosinophilic gastroenteritis is one of the most important primary eosinophilic gastrointestinal disorders. These are defined as disorders that selectively affect the gastrointestinal tract with eosinophil-rich inflammation in the absence of known causes for eosinophilia. The disorders include eosinophilic esophagitis, eosinophilic gastritis, eosinophilic gastroenteritis, eosinophilic enteritis and eosinophilic colitis. Aim of the study: This review focuses on the epidemiology, pathophysiology, clinical features and treatment of primary eosinophilic gastrointestinal disorders with particular attention to primary eosinophilic gastroenteritis. Clinical case: We report a case of a 32-years-old woman that was admitted to our Hospital complaining of abdominal pain, ascites and diarrhea. Laboratory investigations showed a white cell count of 15.1 thousands/mm3 with eosinophilia; other laboratory studies were within the normal limits. Abdominal ultrasonography demonstrated peritoneal effusion and cytological analysis revealed a prevalence of eosinophils in the ascites. The multiple endoscopic biopsies were normal. However, the clinical history, and the laboratory, radiological and endoscopic findings gave a firm diagnosis of the serosal form of primary eosinophilic gastroenteritis. Discussion: This is a rare, benign condition, pathologically characterized by an important eosinophilic infiltration of the wall of the digestive tract and presents a constellation of symptoms that are related to the degree and area of the gastrointestinal tract affected. Primary eosinophilic gastroenteritis encompasses multiple disease entities subcategorized into three types on the basis of the level of histologic involvement: mucosal, muscolaris and serosal forms. Every layer of the gastrointestinal tract can be involved, so that endoscopic biopsy can be normal in patients with the muscolaris subtype, serosal subtype, or both.

Abstract Background: Malignant ovarian Brenner tumors are extremely rare worldwide, accounting for only 1% of malignant ovarian tumors. Their clinical symptoms and pathology are complex and erratic, and the images are mostly non-specific. This poses difficulties in preoperative diagnosis and distinguishing them from other cystic solid ovarian tumors. Here this study has reported on a case of bilateral malignant ovarian Brenner tumor with peritoneal effusion. Case presentation: A 54-year-old woman presented with intermittent vaginal bleeding for more than two months and abdominal pain for one month. Two hard mass of five centimeters with poor movement could be touched at each side of the ovarian areas. The CT findings indicated the presence of two large cystic and solid masses in both adnexal regions. The operation had watched the size of the masses in the bilateral ovarian was both 6cmx6cmx5cm and their surface ulceration showed rotten fleshy tissue. After the operation, combined with morphological and immunohistochemical features, the ovarian specimens were consistent with bilateral ovarian malignant Brenner tumors.Conclusions: Although the incidence of bilateral malignant OBT is extremely low and this disease is extremely rare clinically, the gynecologists should be more informed of its diagnosis and treatment.

Fear Of Cancer

Ovarian fibrothecoma is a rare, benign neoplasm of the sex cords and stroma of the ovary. Patients may present with abdominal pelvic pain and / or distension, and sometimes postmenopausal bleeding. Large tumors (> 10cm) are often associated with pleural and peritoneal effusion mimicking an advanced ovarian malignancy (Deimon –Meigs syndrome). We report 2 cases of giant fibrothecoma associated with ascites and pleurisy. Both patients were postmenopausal. The ovarian tumor was discovered during an increase in abdominal volume in the first patient and as part of the etiological workup of encysted pleurisy in the second. The clinical examination made it possible to objectify a tumor with abdominopelvic development of size greater than 10 cm, the clinical examination also noted, in the two patients, a right basithoracic dullness in favor of a pleurisy and an ascites of average abundance suggesting in the first place a malignant tumor of the ovary, with peritoneal carcinoma. the two patients underwent a pelvic ultrasound, supplemented by an abdominal pelvic CT scan objectifying the presence of a large ovarian mass with pleural and peritoneal effusions. Exploratory laparotomy was required in both patients and underwent an extemporaneous examination which was consistent with the definitive pathological examination in both patients. Both patients underwent total hysterectomy with bilateral adnexectomy and omentectomy with multiple biopsies as the clinical picture was highly suggestive of malignancy. The postoperative follow-up was simple with total regression of peritoneal and pleural effusions in the two cases of Demons-Meigs syndrome. The definitive pathological examination revealed a fibrothecoma. Fibrothecal tumors remain a real challenge from a diagnostic and therapeutic point of view. The fear of cancer is even greater in the presence of Demons-Meigs syndrome. The management of these tumors requires a good clinical and radiological analysis, and it is the histological examination that confirms the diagnosis. The surgery corresponds, in post-menopausal patients, to a hysterectomy with bilateral adnexectomy, while conservative treatment by unilateral adnexectomy is entirely justified in young women who still want fertility.

Abstract CASE DESCRIPTION A 9-year-old castrated male domestic shorthair cat (cat 1) and a 10-year-old castrated male Maine Coon cat (cat 2) were presented for recurrent feline lower urinary tract disease after receiving outpatient care from their primary veterinarians. CLINICAL FINDINGS Physical examination findings for both cats were initially within reference limits. After a short period of hospitalization, both cats developed peritoneal effusion; results of cytologic analysis of a sample of the fluid were consistent with septic peritonitis. During exploratory laparotomy, perforation of the pylorus or proximal portion of the duodenum secondary to ulceration was identified. TREATMENT AND OUTCOME Both cats underwent partial duodenectomy, partial gastrectomy (pylorectomy), and gastrojejunostomy (Billroth II procedure). The cats recovered from surgery and returned to a normal quality of life; however, each had mild episodes of anorexia but maintained a stable body weight. Cat 2 required additional surgery for trichobezoar removal 7 weeks later but recovered quickly. At 7 months after trichobezoar removal, cat 2 developed intermittent vomiting, but clinicopathologic, abdominal ultrasonographic, and upper gastrointestinal tract endoscopic findings were within reference limits. At 9 (cat 2) and 13 (cat 1) months after the Billroth II procedure, both cats were reported to be in good general health and without gastrointestinal signs. CLINICAL RELEVANCE In both cats, the Billroth II procedure was technically straightforward and associated with a full recovery and good medium- to long-term quality of life. A Billroth II procedure could be considered for treatment of cats with large mural lesions in the pyloroduodenal region.
