Anthropometric measurements in male breast cancer

Background: 1% of breast cancers occur in men.The etiology is obscure. An elevated BMI has been postulated to be a cause. Methods: All male breast cancer patients operated from January 1990 to May 2001 were retrospectively reviewed. Relation between BMI and male breast cancer was examined. Results: 43 males underwent breast surgery for breast cancer during this period. 3 patients were excluded from the study because of other risk factors for breast cancer.The average BMI of 40 patients was 26.54 kg/m², which is mildly above the level for normal weight. Conclusions: Excessive adipose tissue may increase risk of male breast cancer.     

Evidence of clinical and genetic heterogeneity in autosomal dominant congenital cerulean cataracts

Autosomal dominant cerulean cataracts (ADCC) have previously been mapped to two loci: one on chromosome 17q24 and the other on chromosome 22q11.2-q12.2, which includes the beta-B2 crystallin (CRYBB2) candidate gene. Using polymorphic markers in these regions (D17S802, D17S836, D17S1806 and CRYBB2, D22S258) for linkage analysis, we excluded these loci in a large Moroccan family presenting with an unusual form of ADCC with early onset of lens opacities and rapid evolution. This finding confirms the clinical and genetic heterogeneity of autosomal dominant congenital cerulean cataracts.     

Can altered production of interleukin-1beta,interleukin-6, transforming growth factor-beta and prostaglandin E(2) by isolated human subchondral osteoblasts identify two subgroups of osteoarthritic patients

OBJECTIVE: To determine the capacity of human subchondral osteoarthritic osteoblasts (Ob) to produce interleukin (IL)-1beta, IL-6, transforming growth factor-beta (TGF-beta) and prostaglandin E(2) (PGE(2)), and determine if a relationship exists between IL-1beta, TGF-beta, PGE(2) and IL-6 production. METHODS: We measured the abundance of IL-1beta, IL-6, TGF-beta and PGE(2) using very sensitive ELISA in conditioned-media of human primary subchondral Ob from normal individuals and osteoarthritic patients. Selective inhibition of IL-6 or IL-6 receptor signaling was performed to determine its effect on PGE(2) production whereas the inhibiton of PGE(2) production was performed to determine its effect on IL-6 production. The expression of bone cell markers and urokinase plasminogen activator (uPA) activity was also determined. RESULTS: Osteoarthritic Ob produced all these factors with greater variability than normal cells. Interestingly, the production of IL-6 and PGE(2) by osteoarthritic Ob separated patients into two subgroups, those whose Ob produced levels comparable to normal (low producers) and those whose Ob produced higher levels (high producers). In those cells classified as high osteoarthritic Ob, PGE(2) and IL-6 levels were increased two- to three-fold and five- to six-fold, respectively, compared with normal. In contrast, while using their IL-6 and PGE(2) production to separate osteoarthritic Ob into low and high producers, we found that IL-1beta levels were similar in normal and all osteoarthritic Ob. Using the same criteria, TGF-beta levels were increased in all osteoarthritic Ob compared with normal. Reducing PGE(2) synthesis by Indomethacin [a cyclo-oxygenase (COX) -1 and -2 inhibitor] reduced IL-6 levels in all osteoarthritic Ob, whereas Naproxen (a more selective COX-2 inhbitor) reduced PGE(2) and IL-6 levels only in the high osteoarthritic group. Conversely, PGE(2) addition to osteoarthritic Ob enhanced IL-6 production in both groups. Moreover, the addition of parathyroid hormone also stimulated IL-6 production to similar normal levels in both osteoarthritic groups. In contrast, using an antibody against IL-6 or IL-6 receptors did not reduce PGE(2) levels in either group. The evaluation of alkaline phosphatase activity, osteocalcin release, collagen type I and uPA activity in osteoarthritic Ob failed to show any differences between these cells regardless to which subgroup they were assigned. CONCLUSIONS: These results indicate that IL-6 and PGE(2) production by subchondral Ob can discriminate two subgroups of osteoarthritic patients that cannot otherwise be separated by their expression of cell markers, and that endogenous PGE(2) levels influence IL-6 synthesis in osteoarthritic Ob.

Asymptomatic Paget’s disease of bone presenting with complete atrioventricular block

Paget＇s disease of bone is a deforming bone disease （osteitis deformans） characterized by increased bone remodeling, bone hypertrophy, and abnormal bone structure, leading to bone expansion, deformities, easy fractures, and occasionally, neoplastic transformation. It is the second most common bone disorder after osteoporosis. The disease is relatively rare in Asia but is common in Europe and North America, affecting approximately 2% of the population over 50 years,     

The value of serum Bcl-2 levels in advanced lung cancer patients

Overexpression of the Bcl-2 protein was associated with a favorable prognostic factor for survival in lung cancer patients, especially nonsmall cell lung carcinoma. The present study was conducted to investigate the value of serum Bcl-2 levels in advanced lung cancer patients. Fifty patients with advanced lung carcinoma pathologically verified and 18 healthy controls were investigated. Serum samples were obtained on the first admission before the chemotherapeutic treatment were given. Serum Bcl-2 levels were determined by using anti-Bcl-2 monoclonal coating antibody. The baseline serum Bcl-2 levels were significantly higher in patients with lung cancer than in the control group (p<0.001). Serum Bcl-2 levels were elevated in 48 (96%) advanced lung cancer patients. None of the prognostic parameters analyzed, such as age of patient, gender, histology, stage of disease, erythrocyte sedimentation rate, serum albumin, hemoglobin, CEA, NSE, LDH, performance of patient, weight loss, and response to chemotherapy, was significantly correlated with Bcl-2 serum concentrations. The serum Bcl-2 concentrations were not changed with cisplatin-based cytotoxic chemotherapy regardless of response (p=0.76). No prognostic value of serum Bcl-2 was determined. In conclusion, the results of the present study, which is the first study to determine serum Bcl-2 levels in lung cancer, suggest that decreased apoptosis occurred due to the effect of serum Bcl-2 elevation in lung cancer patients. Serum Bcl-2 level was of diagnostic but not prognostic value in lung cancer patients. However, more studies are needed to define the role of Bcl-2 in the diagnosis and prognosis of lung cancer.     

Medicolegal childhood deaths in Adana, Turkey

The objective of this study is to determine the characteristics of and changes in the medicolegal childhood deaths that occurred in the provincial center of Adana, and to contribute to the establishment of a database for the development of national and international policies. The study is a retrospective research examining the 1,110 cases in the age group 0 to 18, which were specified as medicolegal deaths in the provincial center of Adana-Turkey between the years 2000-2004. The cases were examined according to age, sex, causes of deaths, the origins and scenes of occurrence. Among all the deaths, 523 cases (47.2%) were seen in the age group of 0-6 years. Accidents account for 900 cases (81.1%), and blunt traumas (594 cases) represent the most common cause of deaths. The share of traffic accidents in total blunt traumas was found to be 441 cases (74.2%). And 270 (24.3%) of all medicolegal deaths occurred as a result of household accidents. The present study has also indicated that the home and surroundings represent the highest-risk areas. As a conclusion, setting up childhood injury prevention committees and providing training programs for parents will be effective for the prevention of childhood injuries and deaths.     

Computerized tomography correlated with CSF protein concentrations.

The authors present a case of hydrocephalus complicated by ventriculitis in which it was possible to correlate the numerical printout of sequential computerized tomograms (CT-Scans) with cerebrospinal fluid protein concentrations obtained by direct ventricular puncture. Different protein levels were unambiguously associated with changes in the absorption numbers on the scan but they did not bear a simple linear relationship to one another. The value of the numerical printout in diagnosis and follow-up is discussed.     

Defective Neutrophil Function in Chronic Granulocytic: Leukaemia

SUMMARY. The ability of neutrophils to phagocytose, kill and digest Candida guilliermondii was investigated in twelve patients with chronic granulocytic leukaemia (CGL). Following ingestion of organisms there was considerable reduction in the ability of CGL cells to kill Candida and this was not explained by a mild impairment of phagocytosis. Histochemical staining showed that granules containing lysosomal enzymes disappear from the cytoplasm of normal neutrophils during killing and digestion of the fungus, while in CGL cells the granules remain. Quantitative measurement confirmed loss of peroxidase from normal neutrophils during Candida killing but no loss from CGL neutrophils. The primary granules of CGL neutrophils do not fuse with and discharge their contents into the phagocytic vacuole and this explains their impaired ability to kill and digest Candida.
