A worldwide overview for hexavalent vaccines and a glimpse into Turkiye's perspective.

The surge in recommended vaccinations for child's has spurred the development of combination vaccines, notably hexavalent vaccines, which provide multiple immunizations in a single dose. These vaccines offer various advantages, such as streamlining vaccination schedules, minimizing injection-related pain and exposure to preservatives, expanding vaccine coverage, and reducing administration costs. However, the intricate and expensive development of these vaccines presents substantial challenges, requiring increased investment and healthcare provider education to optimize their utilization and sustain high vaccination rates. Turkey, known for its robust vaccine coverage, strategic geographic location, and the influx of refugees, is at a critical juncture for integrating hexavalent vaccines into national programs. This transition is especially relevant given the rising vaccine hesitancy and the potential resurgence of vaccine-preventable diseases. This review assesses the deployment of hexavalent vaccines, examining their benefits and challenges through clinical trials and global experiences, with a specific emphasis on Turkiye's public health context.

Functional and radiological results of partial capitate shortening osteotomy in the treatment of Kienböck's disease.

This study assessed the functional and radiological results of partial capitate shortening osteotomy in the treatment of Lichtman stage 2 and 3A Kienböck's disease. Nineteen patients who underwent partial capitate shortening osteotomy between 2014 and 2017 were included. Functional and radiological parameters were assessed both pre- and postoperatively. The mean age was 35 years and the mean follow-up was 16 months. Pain scores, wrist range of motion, hand and finger strength, carpal height ratio and lunate height were significantly improved compared with their preoperative values. Sixteen patients were able to return to work. Ten of them had complete and six had partial revascularization. The mean time taken to return to work was 62 days. No vascularity was achieved in three patients who were unable to return to work. Partial capitate shortening osteotomy is effective in the treatment of stage 2 and 3A Kienböck's disease with successful results both functionally and radiologically. Level of evidence: IV.

Elevated plasma concentrations of S100 calcium-binding protein B and tumor necrosis factor alpha in children with autism spectrum disorders

Objective: To investigate plasma concentrations of S100B (a calcium-binding protein derived primarily from the glia) and inflammatory cytokines in children with autism and the relationship between S100B and cytokine concentrations. Methods: Plasma levels of S100B, tumor necrosis factor alpha (TNF-α), interferon gamma, interleukin (IL)-1β, IL-4, IL-6, IL-10, and IL-17A were measured in 40 unmedicated children with autism and 35 normally developing healthy children. The severity of autism was assessed using the Childhood Autism Rating Scale (CARS). Results: Concentrations of both S100B and TNF-α were higher in children with autism before and after adjusting for a priori-selected confounders (age, sex, and body mass index). S100B concentrations were higher in children with severe autism compared to children with mild-moderate autism. However, this association remained as a trend after adjusting for confounders. S100B concentrations correlated positively with TNF-α concentrations. Conclusion: Our findings showing an increase in peripheral concentrations of S100B and TNF-α provide limited support to the hypothesis about the roles of altered immune function and S100B in autism spectrum disorder (ASD). Studies of larger numbers of well-characterized individuals with ASD are needed to clarify the potential role of the immune system in the pathophysiology of this disorder.

Immune system changes after sexual abuse in adolescents.

BACKGROUND: The immunological changes in diseases such as rheumatoid arthritis and multiple sclerosis have been found to be similar to the immunological changes in adults with post-traumatic stress disorder (PTSD). The biological consequences of and immunological disruptions associated with psychological trauma in sexually abused adolescents were investigated in this study. METHODS: Number of peripheral blood cells, intracellular cytokine level and cytotoxic activity of natural killer cells were measured on routine blood examination samples in adolescents aged 13-18 referred to the outpatient unit for forensic evaluation. Forty-three adolescents (patients with present/lifetime PTSD [PTSD-P/PTSD-L] associated with a history of childhood sexual abuse, n = 33; and 10 controls) were evaluated. RESULTS: Eosinophil percentage was high (P < 0.05), whereas stimulated intracellular interferon-γ was low (P < 0.05) in adolescents with PTSD-L compared with the control group. In PTSD-P patients exposed to repeated sexual abuse, CD3(+) HLA-DR(+) T-lymphocyte count was low (P < 0.05) compared with those with one-time sexual abuse. CONCLUSION: The increase in some immune system parameters and the decrease in several others, suggests a dysregulation of the immune system related to trauma in adolescents. Dysregulation of the immune system is known to cause autoimmune and chronic disease.

Diffuse pulmonary lymphangiomatosis: imaging findings.

Diffuse pulmonary lymphangiomatosis is a rare pulmonary disorder affecting the lymphatic channels from the mediastinum to the pleura. The disease usually occurs in children and young adults and frequently ends with death due to progressive course. Imaging findings of the disease are based on lymphatic involvement which appear as mediastinal soft tissue infiltration and thickening of pulmonary peribroncovascular bundles and interlobular septae. In this report, spiral and high-resolution computed tomography, and ultrasonography findings of severe form of this rare disease are presented. Furthermore, some lymphatic disorders, which are called with similar name but different appearances on imaging, are discussed.
