Aim: Study of the interrelation between the presence of immune deficiency and development of complications during vaccination of newborns with BCG vaccine.
Materials And Methods: In 24 children with complications of vaccine process in the form of cold abscess and lymphadenitis indicators of lymphocyte subpopulation levels were studied by flow cytofluorimetry on Beckman Coulter cytofluoriemter by using monoclonal antibodies with markers CD45+CD3+ - T-cell, CD45+CD3+CD4+ - T-helpers, CD45+CD3+CD8+ - T-supressors-cytotoxic killers, CD45+CD3 CD16+CD56+ - natural killers, CD45+CD3-CD19+ - B-lymphocytes. The level of IgG, IgA, IgM in sera was determined by immune diffusion method in agar by Mancini.
Results: In 4 children selective deficiency of IgA, in 5 - hyper-IgM syndrome was detected, which is an innate immunodeficiency and is characterized by the lack of sera IgA, reduction of IgG level and increase of IgM. In 9 children a reduction of CD16+ natural killer lymphocytes was detected, in some cases combined with a reduction of CD8+ T-supressors-cytotoxic killers.
Conclusion: The reason of development of complications during BCG administration is the presence of immunodeficiency in children. In these children severe course of the vaccine process, presence of axillary lymphadenitis was observed, therapy of these children continued from 4 to 6 months.

Background: Postoperative delirium (POD) is a common complication after major surgery and is associated with poor outcomes in older adults. Early identification of patients at high risk of POD can enable targeted prevention efforts. However, existing POD prediction models require inpatient data collected during the hospital stay, which delays predictions and limits scalability.

Background: Laparoscopic gastrectomy lacks hand-direct tactile sense and has a limited surgical field compared to laparotomy. Apart from textbook classification, there are anatomical variations in the gastric arteries. Laparoscopic gastrectomy presents technical difficulties and necessitates a more comprehensive comprehension of regional anatomy than open surgical procedures.

A 69-year-old Japanese man developed abdominal pain, purpura, proteinuria, and hematuria while receiving treatment for pulmonary tuberculosis. A skin biopsy revealed IgA-positive leukocytoclastic vasculitis, and a renal biopsy showed IgA-positive mesangial proliferative glomerulonephritis with crescent formation. Based on these findings, we diagnosed IgA vasculitis with nephritis (IgAVN) and initiated treatment.

Purpose Of Review: Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disorder predominantly affecting individuals of Mediterranean and Middle Eastern descent, including those with certain heritages including Sephardic Jewish, Armenian, Turkish, and Arab. The disorder affects up to 1 in 200 people making it a very common etiology for pain states worldwide, including serositis mediated painful states of the chest, joint, and abdomen.
Recent Findings: Defined by recurrent episodes of fever and inflammation, FMF can lead to not only severe pain, but complications such as renal amyloidosis, if untreated.
