Cell atypia in breast fine needle aspiration (FNA) can introduce some diagnostic difficulties. Molecules reflecting proliferative cell potential, such as Ki-67 and p27Kip1, can help in recognizing the true biological nature of a cell. Thus, the objective of the study was to analyze the difference in Ki-67 and p27Kip1 cell immunoexpression in breast FNA specimens between fibroadenomas, fibrocystic changes (FCC) with atypia, and breast carcinoma. Microscopic analyses of cell cytomorphology and Ki-67 and p27 Kip1 breast cell immunoexpression were done after standard Pappenheim and immunocytochemical staining (labeled streptavidin-biotin, LSAB) method in autostainer DakoCytomation TechMate™. The study included 50 patients with breast carcinoma, 20 patients with fibroadenoma, and 20 patients with FCC with atypia. High Ki-67 and low or absent p27Kip1 were found in most patients with breast carcinoma, while majority of FCC with atypia were characterized by low Ki-67 and moderate to high p27Kip1 cell immunoexpression. Majority of fibroadenomas were associated with low Ki-67 and low to moderate p27Kip1 cell immunoexpression indicating progressive decrease in cell cycle inhibition, but still not so high proliferative activity as in carcinoma. However, although statistically significant difference for Ki-67 and p27Kip1 was found between breast lesions in our study, the large ranges observed for each marker make them essentially useless for better cytological diagnosis in a single case. Regarding their opposite role in cell cycle, inverse correlation of Ki-67 and p27Kip1 was noticed. Poorly differentiated carcinoma cells had mostly high Ki-67 andlow p27Kip1 cell immunoexpression. © 2010 Wiley-Liss, Inc.

Primary melanoma of the female urethra is a very rare malignant tumor with high mortality. Due to its rarity, there are no guidelines and recommendations on the diagnosis and treatment of such patients, so we aimed to review the reported cases and case series, their treatment, and outcome. We searched through PubMed for all articles reporting on female urethral melanoma. We found 73 articles (case reports and case series) reporting on 112 patients. There are no clinical trials on the topic due to the rarity of the condition. Median patient age at presentation is 68 years. Due to the late presentation, the prognosis of the disease is poor, and median survival is 16 months, with 5-year survival in around 10 % (12 reported patients). Regarding treatment, most authors use either less radical approach (partial or total urethrectomy) or radical approach (anterior pelvic exenteration). We found no evidence that either of the treatment modalities results with higher survival. In local excision, there are indications that margins less than 2-2.5 cm result in high percentage of local recurrence suggesting that resection width should be at least 2.5 cm. For localized urethral melanoma, local resection with margins of 2.5 cm can be recommended and there is no foundation to support radical surgery in such patients. Chemotherapy and immunotherapy can also recommend. For locally advanced disease, the prognosis is poor, and radical surgery will not improve survival significantly. © 2012 Springer Science+Business Media New York.

Temporomandibular disorders are a form of musculoskeletal disorders, which reduce the function of stomatognathic system and they are related to some other diseases causing painful conditions and disorders of oral function. The aim of this paper is to describe a one year follow up clinical case of a female patient with comorbid multiple sclerosis and a relatively rare form of articular disc disorder. Primary clinical diagnostics encompassed manual methods of TMJ examination. Definite diagnosis included radiologic examination. Clinical hyperextensive condyle position was palpated bilaterally and subsequently confirmed by a functional panoramic radiograph of TMJ. The anterior displacement of disc with reduction was diagnosed by magnetic resonance and in the right joint there was a disc displacement upon excursive movement. From relevant literature, the relationship of a number of diseases that can be related to functional disorder of the orofacial system, such as multiple sclerosis, has been described from many aspects. Also, apart from the standard classification of one form of anterior displacement of the disc, made primarily by magnetic resonance, cases of disc displacement upon excursive mandibular movement can rarely be found in literature.

Metabolic syndrome (MetS) is the occurrence of diabetes mellitus/glucose intolerance, arterial hypertension, central obesity, dyslipidemia, and microalbuminuria in the same patient (definition by WHO). Presence of metabolic syndrome is associated with larger myocardial infarction size and complications following acute myocardial infarction. Two hundred and thirty patients with acute coronary syndromes were analyzed. Those with MetS (n=141) included patients with diabetes mellitus/glucose intolerance and at least two of the following criteria: hypertension, hypertriglyceridemia/low HDL cholesterol, android obesity/body mass index (BMI) ≥ 30, or microalbuminuria. Control group did not meet criteria for MetS. Presence of heart failure was assigned according to Killip classification. The MetS group had larger myocardial infarction size determined by peak creatine-kinase (CK) (1484±1354 vs. 981±890, p = 0.003) and CK MB (141±117 vs. 95±78, p = 0.002). While in non-MetS group males had larger myocardial infarction than females, in MetS group females had larger myocardial infarction than males. Cardiac failure occurred more in MetS group of patients, again was more prominent in females. Occurrence of metabolic syndrome in acute coronary syndrome patients predisposes to larger myocardial infarction size, more on the account of female patients having MetS. MetS, again particularly in females, predisposes to higher chance of having heart failure during acute coronary syndrome. Recognizing the female group with MetS as of higher risk for large myocardial infarction and heart failure leads us to pay special attention on this patient population. © The Japan Endocrine Society.

Primary melanoma of the glans or male urethra is a rare malignant tumor with high mortality. We searched PubMed and found 129 articles reporting on 220 patients. All articles were case reports or case series. Median patient age was 65 years. Median survival was 28 months, with 5-year survival in approximately 10%. All patients who survived over 5 years had a localized disease (stage I/A) with invasion depth <3-3.5 mm. Wide local excision with sentinel lymph node biopsy is the treatment of choice for patients with localized disease. For advanced disease, the prognosis is poor.
