determining the primary site of metastatic adenocarcinoma in Serous Fluid a cytological study
Chinese Journal of Pathology, 2005Co-Authors: Fang Fang, Li Yang, Xilai Su, Qing HeAbstract:OBJECTIVE: To explore cytological parameters that may identify the primary sites of metastatic adenocarcinomas in Serous Fluid. METHODS: Serous Fluid specimens from 89 cases of metastatic adenocarcinomas (40 metastatic adenocarcinomas of lung, 6 metastatic adenocarcinomas of breast, 21 metastatic ovary adenocarcinomas, 22 metastatic gastrointestinal and pancreatic adenocarcinomas) were studied by using multiple morphologic parameters. Immunocytochemical S-P method was used to detect the expression of CA125, CA199, SPB and TTF-1 in 75 cases. RESULTS: Metastatic adenocarcinomas of different primary sites displayed certain different morphologic features, including the total amount of tumor cells, size of clusters, ratio of clusters over single cells, configuration of tumor clusters and the background of the smear. Cell clusters of small to medium sizes represented 95% and 100% in the metastatic adenocarcinomas of lung and breast, respectively. Most of the ovarian metastatic adenocarcinomas (85.7%) presented some large cell clusters and larger amount of cells, whereas certain metastatic gastrointestinal and pancreatic adenocarcinomas (45.5%) presented smaller number of cells and predominantly to be single cell in distribution (40.9%). Psammoma bodies were found in metastatic adenocarcinomas of lung and ovary. SPB and TTF-1 expression supported the diagnosis of adenocarcinoma of pulmonary origin. CA125 expression supported an ovarian origin. Although CA199 was seen in all groups of metastatic adenocarcinomas, nevertheless, its appearance in tumor cells in ascitic Fluid specimens supported gastrointestinal and pancreatic origins. CONCLUSION: Morpho-logic features of the cytological smear, immunohistochemical staining and clinical history are equally important in determining the primary sites of metastatic adenocarcinomas in Serous Fluid.

Increased Diagnostic Yield of Tuberculous Serositis by Using Serous Fluid Drainage Flocky Precipitate (SFDFP) as a Testing Sample.
Scientific Reports, 2019Co-Authors: Aimei Zhang, Yao Zhang, Shuihua Lu, Yuanlin Song, Shanqun LiAbstract:A definitive diagnosis of tuberculosis serositis (TS) is still challenging. Our preliminary practice found that Serous Fluid Drainage Flocky Precipitate (SFDFP) was a useful testing sample to diagnose TS. We designed this study to assess the diagnostic performance of SFDPF for TS compared with conventional bacteriology methods on Serous Fluid (SF). A cohort study was conducted from July 2014 to April 2016. Patients with suspected TS were consecutively screened. SF and SFDFP were collected and tested by Ziehl-Neelsen stain, MTB culture, and Xpert/RIF assay. We compared the diagnostic performance of SF and SFDFP in several test settings. Through this study, 85 patients were enrolled, of whom 70 (82.4%) were confirmed TS or highly probable TS, 13 (15.3%) were none-TS and 2 (2.4%) indeterminate results were ruled out. The overall sensitivity using both SFDFP and SF was significantly higher than each (60% vs. 48% and 41%, p

The overall sensitivity using both SFDFP and SF was significantly higher than each (60% vs. 48% and 41%, p < 0.05). SFDFP and SF samples had similar diagnostic performance (p < 0.05). No false positive was detected in this study. We concluded that SFDFP is a reliable testing sample for diagnosing tuberculous serositis. SFDFP may significantly improve the diagnostic yield as a supplement to conventional tests.

sarcoptic mange of gazelle gazella subguttarosa and its medical importance in iran
Parasitology Research, 2007Co-Authors: Taghi Taghipour Bazargani, Javad A Hallan, S Nabian, S RahbariAbstract:Sarcoptes scabiei infestation was diagnosed in four freshly dead and three net-captured gazelle while ranging freely. The captured animals presented with an alopecic pruritic skin disease with signs of crusted skin lesions, numerous small nodules which first appeared on the lips or nostrils and then it also extended towards the eyelids, around the ears, and, in some cases, over entire face, neck, trunk, and legs. Skin over the affected area gradually became bald, thick and hard, being dry and doughy to the touch, and Serous Fluid or sometimes blood oozes from the lesions which had a severe malodor. Skin scrapings confirmed the presence of the mite S. scabiei. Histopathology of lesions demonstrated marked acanthosis, hyperkeratosis, and parakeratosis. Microscopical examination also revealed all stages of S. scabiei, which were located mainly in the stratum corneum and also in the stratum granulosum. During the capture and sampling of the animals, four persons ranging in age from 25 to 62 years were exposed to scabies. Two relatives of one of them have been also affected by familiar contact. Clinical signs appeared within 9 days of exposure. They developed several pruretic erythematous papules with intense itching.
