HIV‐negative case of bacillary angiomatosis with chronic hepatitis B

Bacillary angiomatosis (BA) is an infectious disease which occurs predominantly in immunosuppressive patients and rarely in immunocompetent individuals. We had a case of BA who presented with a red cutaneous nodule on his left leg of which histopathological examination revealed marked lobular proliferation of capillaries throughout the interstitium and clusters of bacilli with hematoxylin–eosin and Warthin–Starry stains, respectively. Antibody titer against Bartonella henselae was 1/32. The only systemic disease the patient had was chronic hepatitis B. HIV was negative and no other immunosuppressive status was established. In this case we believe that the immunological differences secondary to chronic hepatitis B could have caused a tendency for the disease development.

Tooth sensitivity experience among residential university students Abstract: Objectives: The aim of this study was to assess the experience of residential University students about ‘sensitive teeth’. Subject and methods: Self‐administered questionnaires were given randomly to students in all the residential hostels located in the University campus. Data on presence of sensitive teeth, initiating stimulus and duration of each episode of discomfort were elicited. History of common aetiological factors of tooth sensitivity was also taken. Results: One thousand and nineteen responses (650 males; 369 females) were analysed in this study. Approximately 697 (68.4%) volunteers claimed to have sensitive teeth. Majority described their discomfort as sharp pain, cold as the initiating stimulus and drinking was mostly interfered with. Tooth sensitivity was found to be common among hard toothbrush users. Multiple regression analysis showed that hard toothbrush had a significant association with tooth sensitivity. Other common aetiological factors, such as history of gastric acid reflux, vomiting, soft drinks and the use of vitamin C were found to have a weak association with tooth sensitivity. Conclusion:  Prevalence of tooth sensitivity was 68.4%. Presence of tooth sensitivity among these students was associated more with history of hard toothbrush use contrary to widely held belief that erosive agents were mostly responsible. Future studies are needed to provide more epidemiological data on tooth brushing and tooth sensitivity.

Bone morphogenetic protein‐9 induces epithelial to mesenchymal transition in hepatocellular carcinoma cells

Epithelial‐mesenchymal transition (EMT) is an important mechanism to initiate cancer invasion and metastasis. Bone morphogenetic protein (BMP)‐9 is a member of the transforming growth factor (TGF)‐β superfamily. It has been suggested to play a role in cancer development in some non‐hepatic tumors. In the present study, two hepatocellular carcinoma (HCC) lines, HLE and HepG2, were treated with BMP‐9 in vitro, and phenotypic changes and cell motility were analyzed. In situ hybridization (ISH) and immunohistochemical analyses were performed with human HCC tissue samples in order to assess expression levels of BMP‐9. In vivo, BMP‐9 protein and mRNA were expressed in all the tested patients to diverse degrees. At the protein level, mildly positive (1 + ) BMP‐9 staining could be observed in 25/41 (61%), and moderately to strongly positive (2 + ) in 16/41 (39%) of the patients. In 27/41 (65%) patients, the BMP‐9 protein expression level was consistent with the mRNA expression level as measured by ISH. In those patients with 2 +  protein level, nuclear pSmad1 expression in cancer cells was also significantly increased. Expression of BMP‐9 was positively related to nuclear Snail expression and reversely correlated to cell surface E‐cadherin expression, although this did not reach statistical significance. Expression levels of BMP‐9 were significantly associated with the T stages of the investigated tumors and high levels of BMP‐9 were detected by immunofluorescence especially at the tumor borders in samples from an HCC mouse model. In vitro, BMP‐9 treatment caused a reduction of E‐cadherin and ZO‐1 and an induction of Vimentin and Snail expression. Furthermore, cell migration was enhanced by BMP‐9 in both HCC cell lines. These results imply that EMT induced by BMP‐9 is related to invasiveness of HCC.     

A polymorphism within the connective tissue growth factor (CTGF) gene has no effect on non-invasive markers of beta-cell area and risk of type 2 diabetes

Chromosomal locus 6q23 is strongly linked to type 2 diabetes (T2DM) and related features including insulin secretion in various ethnic populations. Connective tissue growth factor (CTGF) gene is an interesting T2DM candidate gene in this chromosome region. CTGF is a key mediator of progressive pancreatic fibrosis up-regulated in type 2 diabetes. In contrast, CTGF inactivation in mice compromises islet cell proliferation during embryogenesis. The aim of our study was to investigate an impact of CTGF genetic variation on pancreatic beta-cell function and T2DM pathogenesis. We studied the effect of a common CTGF polymorphism rs9493150 on the risk of the T2DM development in three independent German cohorts. Specifically, the association between CTGF polymorphism and non-invasive markers of beta-cell area derived from oral glucose tolerance test was studied in subjects without diabetes. Neither in the Metabolic Syndrome Berlin Potsdam (MESYBEPO) study (n=1026) (OR=0.637, CI (0.387-1.050); p=0.077) nor in the European Prospective Investigation into Cancer and Nutrition-Potsdam (EPIC-Potsdam) (n=3049) cohort (RR=0.77 CI (0.49-1.20), p=0.249 for the recessive homozygote in general model), a significant association with increased diabetes risk was observed. The risk allele of rs9493150 had also no effect on markers of beta-cell area in the combined analysis of the MESYBEPO and Tübingen Family Study (n=1826). In conclusion, the polymorphism rs9493150 in the 5'-untranslated region of the CTGF gene has no association with T2DM risk and surrogate markers of beta-cell area.
