Left bundle branch block without a typical contraction pattern is associated with increased risk of ventricular arrhythmias in cardiac resynchronization therapy patients

The International Journal of Cardiovascular Imaging - Cardiac resynchronization therapy (CRT) reduces the risk of ventricular arrhythmias (VA) in heart failure (HF) patients with left bundle branch...     

Nonsyndromic X‐linked intellectual deficiency in three brothers with a novel MED12 missense mutation [c.5922G>T (p.Glu1974His)]

X‐linked intellectual deficiency (XLID) is a large group of genetic disorders. MED12 gene causes syndromic and nonsyndromic forms of XLID. Only seven pathological mutations have been identified in this gene. Here, we report a novel mutation segregating with XLID phenotype. This mutation could be in favor of genotype–phenotype correlations.     

Retrospective study of the distribution and the fertility of hydatid cysts in the child in Tunisia

Purpose of the study

Our aim was to study the distribution and the fertility of the hydatid cysts in function of the age and the sex of patients and to identify the strain(s) responsible(s) of the children hydatidosis.

Patients and methods

We have analyzed a total of 241 cysts coming from 195 children aged 2 to 16 years operated in the CHU F. Bourguiba of Monastir during the period from November 1999 to December 2009. For each cyst, the localization and the fertility of the métacestode as well as age, sex and origin of the patient are listed. Identification of strains was carried out by PCR/RFLP and has targeted the ribosomal gene ITS1.

Results

The lung was the primary localization of cyst (61.8%) followed by the liver (34.85%). The greatest number of cases is observed in the age groups 4–9 years (138 cases) where children's infection is more frequent in the male than in the female sex. The fertility of the cyst was independent of its site or its size and no incidence of age of children was detected. The G1 sheep strain is responsible for the contamination of children.

Conclusion

The cystic echinococcosis described as a young adult disease may actually observed at any age and remains a serious problem of public health in Tunisia.
