Detection of Helicobacter pylori and determination of clarithromycin susceptibility using formalin-fixed, paraffin-embedded gastric biopsy specimens by fluorescence In situ hybridization
Background: Clarithromycin resistance and poor compliance to therapy are often responsible for Helicobacter pylori eradication therapy failure
Irritable bowel syndrome in persons who acquired trichinellosis.
BACKGROUND AND AIM: The postinfectious irritable bowel syndrome (PI-IBS) frequently follows bacterial infections. Since people suffering from PI-IBS and Trichinella spiralis-infected mice develop similar findings, this animal model has been successfully used for PI-IBS studies; however, IBS has never been studied in humans after trichinellosis. The aim of this study was to evaluate the IBS symptoms in people who had acquired trichinellosis. PATIENTS AND METHODS: A large outbreak of trichinellosis caused by Trichinella britovi occurred in Izmir, Turkey, in 2003-2004. The diagnosis of trichinellosis was confirmed by serology and muscle biopsy. After clinical and laboratory evaluations, 72 patients (38 women, 34 men, mean age 33.2 +/- 10.4 yr) with trichinellosis without preexisting IBS were enrolled in the study. Noninfected people (N = 27) were used as control group. A questionnaire was developed to assess symptoms of IBS and alarm symptoms. The first interview was done face-to-face. After 2, 4, and 6 months of the first interview, the questionnaire was readministered to the patients without any information on the occurrence of a previous trichinellosis syndrome, while it was applied after a year only to the patients who had suffered IBS symptoms according to at least one of the previous interviews. RESULTS: According to Rome II criteria, PI-IBS developed in 10 of 72 (13.9%) people with confirmed trichinellosis, who had no preexisting IBS. The rate of PI-IBS was 13.9% and 13.9% at the 4th and 6th months, respectively. The symptoms of PI-IBS persisted in five of them up to 1 yr. People without trichinellosis did not develop any IBS symptoms. CONCLUSIONS: This is the first report of the development of PI-IBS after T. britovi. Consequently, IBS can be considered as a secondary syndrome induced by trichinellosis

Familial Mediterranean fever (FMF) in Turkey: results of a nationwide multicenter study
Familial Mediterranean fever (FMF) is an autosomal recessive disease that is prevalent among eastern Mediterranean populations, mainly non-Ashkenazi Jews, Armenians, Turks, and Arabs. Since a large proportion of all the FMF patients in the world live in Turkey, the Turkish FMF Study Group (FMF-TR) was founded to develop a patient registry database and analyze demographic, clinical, and genetic features. The cohort was composed of 2838 patients (mean age, 23.0 +/- 13.33 yr; range, 2-87 yr), with a male:female ratio of 1.2:1. There was a mean period of 6.9 +/- 7.65 years from disease onset to diagnosis; the period was about 2 years shorter for each decade since 1981. Ninety-four percent of patients were living in the central-western parts of the country; however, their familial origins (70% from the central-eastern and Black Sea regions) reflected not only the ongoing east to west migration, but also the historical roots of FMF in Turkey. Patients' clinical features included peritonitis (93.7%), fever (92.5%), arthritis (47.4%), pleuritis (31.2%), myalgia (39.6%), and erysipelas-like erythema (20.9%). Arthritis, arthralgia, myalgia, and erysipelas-like erythema were significantly more frequent (p < 0.001) among patients with disease onset before the age of 18 years. Genetic analysis of 1090 patients revealed that M694V was the most frequent mutation (51.4%), followed by M680I (14.4%) and V726A (8.6%). Patients with the M694V/M694V genotype were found to have an earlier age of onset and higher frequencies of arthritis and arthralgia compared with the other groups (both p < 0.001). In contrast to other reported studies, there was no correlation between amyloidosis and M694V homozygosity in this cohort. However, amyloidosis was still remarkably frequent in our patients (12.9%), and it was prevalent (27.8%) even among the 18 patients with a disease onset after age 40 years. Twenty-two patients (0.8%) had nonamyloid glomerular diseases. The high prevalence of vasculitides (0.9% for polyarteritis nodosa and 2.7% for Henoch-Schonlein purpura) and high frequency of pericarditis (1.4%) were striking findings in the cohort. Phenotype II cases (those patients with amyloidosis as the presenting or only manifestation of disease) were rare (0.3% or less). There was a high rate of a past diagnosis of acute rheumatic fever, which suggested a possible misdiagnosis in children with FMF presenting with recurrent arthritis. To our knowledge, this is the largest series of patients with FMF reported from 1 country. We describe the features of the disease in the Turkish population and show that amyloidosis is still a substantial problem
