[Can cross-allergic reactions to food antigens be the cause of recurrent pancreatitis in children with food allergies?].

Drug and food allergy in 80% of cases are the cause of duodenal inflammation disrupting the function of the pancreatic ducts. However, in some cases, elimination diet in patients with food allergy does not provide a sufficient effect. The article shows the effect of cross-allergic reactions on recurrent pancreatitis in 28 children with food allergy (mean age 11.

Efficient differentiation of Mycobacterium tuberculosis strains of the W-Beijing family from Russia using highly polymorphic VNTR loci.

The W-Beijing family is a widespread Mycobacterium tuberculosis clonal lineage that frequently causes epidemic outbreaks. This family is genetically homogeneous and conserved, so ETR-VNTR (exact tandem repeat-variable number of tandem repeats) typing is insufficient for strain differentiation, due to a common ETR-A to E profile (42435). This leads to the false clustering in molecular epidemiological studies, especially in the regions of predominance of the W-Beijing family.

[Differentiation of the Mycobacterium tuberculosis W-Beijing family strains from the Russian Federation by the VNTR-typing].

Recent phylogenetic studies allowed the Mycobacterium tuberculosis complex to be divided into a number of the strain families. The W-Beijing family is one of most widespread M. tuberculosis variants frequently causing epidemic outbreaks.

[Clinical application of VNTR-typing of Mycobacteria tuberculosis strains: monitoring of treatment quality and of laboratory service].

An early diagnosis of super-infection and mixed infection of Mycobacteria tuberculosis is highly important for the correction of an assigned treatment and for a positive prognostication. An analysis of loci with varying tandem repeats (VNTR) is a simple in use and reproducible method of M. tuberculosis genotyping.

[Diagnosis and surgical treatment of intussusception in children].

The article discusses the methods of diagnosis and surgical treatment of intussusception of the intestine in children according to the stages of the disease. Colonoscopy is recommended for wide use; it helps in making the precise diagnosis in an atypical clinical picture of intussusception in the early periods, revealing the indications for operative treatment, and determining the volume of the intervention on basis of objective control of the degree of injury suffered by the strangulated intestine.
