This study aimed to determine phenotypic and genotypic drug resistance patterns of strains from children with tuberculosis (TB) in China and Russia, two high-burden countries for multi/extensively-drug resistant (MDR/XDR) TB. Whole-genome sequencing data of isolates from China ( = 137) and Russia ( = 60) were analyzed for phylogenetic markers and drug-resistance mutations, followed by comparison with phenotypic susceptibility data. The Beijing genotype was detected in 126 Chinese and 50 Russian isolates.

Purpose: Osteomyelitis is a group of bone infectious (bacterial osteomyeilitis-BO) and noninfectious inflammatory diseases (nonbacterial osteomyelitis-NBO) with similar clinical, radiology, and laboratory features. Many patients with NBO are misdiagnosed as BO and receive unnecessary antibiotics and surgery. Our study aimed to compare clinical and laboratory features of NBO and BO in children, to define key discriminative criteria, and to create an NBO diagnostic score (NBODS).

Brucellosis is highly contagious zoonotic bacterial disease caused by gram-negative genus. It has a wide spectrum of clinical manifestations and due to variety and nonspecificity of clinical signs the diagnostics can be very complicated. We present a clinical case of severe chronic brucellosis in a 5-years old boy with long-term course of disease and multiorgan involvement.

Background: Bacillus Calmette-Guierin (BCG) vaccination complications are common in inborn errors of immunity (IEI) due to the inability to clear live attenuated Mycobacterium bovis. Various BCG-vaccine strains are used worldwide, and the profile of the Russian BCG strain vaccine complications in IEI is poorly characterized.

Objective: To evaluate risks of BCG infection in a large cohort of patients with IEI vaccinated with the Russian BCG strain.

Objectives: Our study aimed to evaluate the cytokine levels in pediatric chronic non-bacterial osteomyelitis (CNO) patients and compare these with other immune-mediated diseases and healthy controls.

Methods: In this prospective study, we included 42 children with CNO, 28 patients with non-systemic juvenile idiopathic arthritis (JIA), 17 children with insulin-dependent diabetes mellitus (IDDM), and 30 healthy age-matched controls. In each of the CNO patients and comparison groups, the levels of 14-3-3-η protein, S100A8/A9 protein, interleukin-4 (IL-4), interleukin-17 (IL-17), interleukin-18 (IL-18), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) were measured by ELISA assay.

Article Synopsis
  • The study investigates the genetic variations in Bacille Calmette-Guérin (BCG) vaccine strains, specifically focusing on seed lots used in Russia and their descendants linked to BCG-related diseases in children.
  • Through whole-genome sequencing, researchers compared seed lots 361, 367, and 368 with nine progeny isolates and identified specific genetic mutations that could influence vaccine efficacy and virulence.
  • The findings suggest that while genetic variations exist, they did not compromise the stability or effectiveness of the BCG vaccine, indicating that changes accumulate during the vaccine's time in the human body.

Chronic nonbacterial osteomyelitis (CNО) and tuberculous osteomyelitis (TBO) are both primarily chronic inflammatory bone diseases with similar clinical and radiological findings, but entirely different in aetiology, pathogenesis, treatment, and outcomes. Our study aimed to evaluate the clinical and laboratory features which could discriminate the CNO and TBO. The study included 124 patients-91 with CNO and 33 with TBO.

Chronic non-bacterial osteomyelitis (CNO) is a group of immune-mediated diseases which appears in bone inflammation, destruction and some orthopaedic consequences, especially in the cases of spinal involvement. This study is to compare characteristics and treatment outcomes of CNO patients with spinal involvement. The retrospective cohort study included data from 91 pediatric patients with CNO.

Purpose: To evaluate the influence of anterior fusion option on the short- and long-time outcomes on multilevel spinal reconstructions in young children.

Methods: Forty-five patients aged under 4 years old (2 years 2 months ± 11 months in average) underwent spinal reconstruction due to tuberculosis spondylitis (35), pyogenic spondylitis (9) and spinal tumors (1) complicated by angular kyphosis exceeded 20° (49.2° ± 14.

Extrapulmonary and, in particular, spinal tuberculosis (TB) constitutes a minor but significant part of the total TB incidence. In spite of this, almost no studies on the genetic diversity and drug resistance of Mycobacterium tuberculosis isolates from spinal TB patients have been published to date. Here, we report results of the first Russian and globally largest molecular study of M.

Operations for tuberculosis and BCG lesion of the sternum were performed on 70 children of preschool age. Clinico-epidemiological features, results of complex X-ray investigation and complex treatment were analyzed. It was noted that in the recent years the number of children with the pathology in question became greater, the possibilities of standard roentgenography for the diagnosis are limited, computed tomography is of high diagnostic value as well as the efficiency of radical operations fulfilled against the background of combined antituberculous chemotherapy.

DST was ascertained to have a high sensitivity in virtually all patients with tuberculosis and a positive reaction was first noted in the infected. With stabilization and regression, the response to DST was much less pronounced than that in clinical and primary infection (that to the Mantoux test being more evident). DST showed its use as a marker of active tuberculosis not only in its local forms, but also in latent tuberculous infection.

A new reagent for a skin test given the name Diaskintest has been designed for the screening diagnosis of tuberculosis and preclinical and clinical trials conducted. Preclinical trials were carried out on 315 laboratory animals (guinea-pigs, albino mice). The reagent Diaskintest was ascertained to be nontoxic, to have no sensitizing properties, to be safe and specific, and to induce no positive reactions in BCG-vaccinated animals and healthy guinea-pigs.

The growth of the unit of vertebrae and intact vertebrae outside and within the instrumental fixation area was studied in children operated on for tuberculosis spondylitis complicated by severe kyphotic deformity. There was a considerable growth retardation of blocked vertebrae after radical spinal repair from the growth of intact vertebrae. Instrumental fixation of the vertebral column after its radical reconstruction causes no considerable retardation of the vertical growth of intact vertebral bodies; however, it leads to the advanced growth of their anterior versus posterior portions, which mediates a supplementary self-correction of residual kyphosis during growth.

Thirteen of 84 children with tuberculous ostitis of the proximal tibial portion were repeatedly operated on 1.5 to 12 years after radical reconstructive surgery due to developed orthopedic sequels. Deformities of the tibia were found to develop in the earliest period and tibial shortening formed significantly later.

Procedures for anterior spine fusion and posterior instrumental spinal fixation have been developed for the surgical treatment of childhood tuberculous spondylitis complicated by severe kyphotic deformity. The optimum method of the instrumental fixation is the use of multisupport constructions with the heterodirectional action of corrective efforts (in 15 children). Anterior osteoplastic stabilization of the vertebral column, by applying brace cortical grafts with saddle-shaped hollows on the tips of its ventral projection, was applied in 6 children.
