Multiple endocrine neoplasia type 2A (MEN 2A) is an autosomal dominant inherited condition with a prevalence of one in 40?000 individuals. It causes the development of tumours in endocrine glands, such as medullary thyroid cancer, pheochromocytomas, as well as primary hyperparathyroidism. MEN 2A in pregnancy is very rare with only 29 cases reported in the literature. The presence of pheochromocytoma is a rare cause of hypertension during pregnancy with an incidence of 0.007% of all pregnancies. This has severe implications on both mother and the foetus. This case report describes a 22-year-old nulliparous Caucasian woman with known MEN2A syndrome, who underwent thyroidectomy for medullary thyroid carcinoma in childhood and excision of left sided pheochromocytoma at the age of 19. She was found to have a recurrence of pheochromocytoma in the right adrenal gland during pregnancy at 16 weeks of gestation and was oddly normotensive. Catecholamine effects were blocked with phenoxybenzamine and she delivered by an uneventful elective caesarean section at 36 weeks gestation. She underwent a laparoscopic right adrenalectomy six weeks postpartum, followed by lifelong corticosteroid replacement. 相似文献

Pseudomonas aeruginosa has the potential to achieve resistance to carbapenems via the acquisition of carbapenemase-encoding genes, the downregulation of the OprD porin, the overexpression of efflux systems and the overproduction of cephalosporinases. One hundred and fifty carbapenem-non-susceptible isolates from 2008 to 2010 were screened for carbapenemase production, OprD porin loss, efflux pumps overexpression and inducible AmpC beta-lactamase production. For comparison reasons, the presence of the same mechanisms was also assessed in a previous collection of 30 carbapenem-non-susceptible P. aeruginosa isolated between 2003 and 2005. Results showed the accumulation of various resistance mechanisms among VIM-2 producers isolated between 2008 and 2010 with a parallel considerable increase in imipenem MIC90 and the geometric mean of the MIC values of imipenem and meropenem between the two study groups. The accumulation of carbapenem resistance mechanisms highlights the potential of this formidable pathogen for evolutionary success under antibiotic selective pressure. 相似文献

In June 2010, a severe outbreak of 13 cases of post-cataract surgery endophthalmitis caused by multidrug-resistant Pseudomonas aeruginosa occurred. Pulse-field gel electrophoresis in eye isolates found 95% genetic similarity; however, extensive environmental and carriage investigation revealed no source of infection. 相似文献

This study assessed immunity to poliomyelitis in a representative sample of 1064 persons living in northern Greece. Antibody prevalences in the individuals tested were 91.1% (95% confidence interval (CI): 89.4-92.8), 92.1% (95% CI: 90.5-93.7) and 83.1% (95% CI: 80.8-85.4) for poliovirus types 1, 2 and 3, respectively. For poliovirus type 3, a gap in immunity was found in individuals aged 10-29 years. Re-vaccination of adolescents living in northern Greece is suggested to ensure herd immunity and to minimise the risk of importation of wild poliovirus from endemic countries. 相似文献

Human brucellosis is a significant public health problem in many Mediterranean countries including Greece. The conventional serological methods, as well as blood cultures, have serious limitations, especially in chronic, relapsing, and focal forms of the disease. Four different PCR assays were applied in 4,926 buffy coat, whole-blood, and serum samples received from 200 patients admitted with brucellosis to the Infectious Diseases Hospital, Thessaloniki, Greece, for the rapid diagnosis of acute infection and relapses and compared to blood culture and serological tests (i.e., Wright's seroagglutination test, Coombs' antibrucella test, and the complement fixation test). The four PCR assays had excellent sensitivity and specificity and were able to detect all of the cases of acute disease. Buffy coat and whole blood were the optimal specimens. All four PCR assays were negative in all follow-up samples from 183 patients who had completed a successful treatment and were positive in all follow-up samples from 17 patients who had relapses in the first year after therapy, including the times of the relapses. In conclusion, PCR is a very useful tool for the rapid diagnosis of acute brucellosis and a good marker for the posttreatment follow-up and the early detection of relapses. 相似文献

The aim of this study was to investigate CXCL-1 chemokine levels in the vitreous during rhegmatogenous retinal detachment (RRD) with and without proliferative vitreoretinopathy (PVR) and identify possible correlations with clinical parameters (extent and duration or RRD and PVR grade). Vitreous samples from patients with primary RRD with or without PVR were collected and assayed using a double antibody enzyme-linked immunosorbent assay (ELISA). Eleven vitreous samples from organ donors were employed as a control group. CXCL-1 levels were measured in 35 vitreous samples from 35 RRD patients. Mean CXCL-1 levels (64·82 ± 6·47 pg/ml) were significantly higher (P = 0·048) compared to controls. There was a significant positive correlation between CXCL-1 levels and the extent of the detachment (r = 0·794, P = 0·006). Peak CXCL-1 levels coincided with 3+ quadrant RRD, an interim of 29–60 days’ duration and PVR grade B. Increased CXCL-1 levels may be indicative of mild inflammation in the detached retina and the adjacent vitreous. The results of the present study may provide novel insight into the complex interactions taking place during the early and late stages of RRD complicated by PVR. 相似文献

Occurrence of Bartonella henselae and Bartonella quintana in a healthy Greek population 总被引:1,自引:0,他引:1

The purpose of this study was to determine the prevalence of IgM and IgG antibodies against Bartonella henselae and B. quintana in a healthy Greek population using a commercially available immunofluorescent test (Focus test). Five hundred healthy individuals were divided by sex into four age groups and three groups according to contact with cats. IgM antibodies were not detected in any of the subjects examined, while 99 (19.8%) and 75 (15%) were IgG seropositive to B. henselae and to B. quintana, respectively. No statistical difference in the seropositivity was observed among these groups. The IgG antibody titers ranged from 1/64 to 1/256 for B. henselae and from 1/64 to 1/512 for B. quintana. A high percentage (12.4%) of cross-reactivity between the two species was observed. Our data show that the prevalence of both Bartonella species in Greece is high. However, low IgG antibody levels are not sufficient evidence of active infection. 相似文献
