Alterations in Inflammatory Markers and Cognitive Ability after Treatment of Pediatric Obstructive Sleep Apnea.

: Determination of the impact of obstructive sleep apnea (OSA) on the cognitive function (CF), and serum tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and 1β levels and the effect of OSA management on these variables in children. : A total of 224 patients were evaluated using the Pediatric Sleep Questionnaire, the NEPSY score for CF, and polysomnography (PSG) to grade OSA severity according to the apnea/hypopnea index (AHI). Adentonsillectomy (AT) was performed for patients with adenotonsillar hypertrophy grade > 2.

Recurrent respiratory infections and vitamin A levels: a link? It is cross-sectional.

Respiratory tract infections are common illnesses in children, causing significant morbidity and negatively affecting their health. Vitamin A protects against infections and maintains epithelial integrity. The goal of this study was to determine the correlation between vitamin A deficiency and recurrent respiratory tract infections (RRTIs).

Effect of PUVA therapy on melanocytes and keratinocytes in non-segmental vitiligo: histopathological, immuno-histochemical and ultrastructural study.

Background And Aims: Psoralen ultraviolet A (PUVA) is an important modality in treating vitiligo. Its effect on melanocytes and keratinocytes is not sufficiently studied. In this work, we investigated 30 cases of non-segmental vitiligo regarding the changes of melanocytes and keratinocytes in both vitiliginous and nearby areas before and after PUVA therapy.

Patterns of repigmentation in two cases of hypopigmented type of vitiligo.

It has been observed that depigmentation in vitiligo passes through two stages; patches of light brown hypopigmentation which gradually changes into milky white patches. In this work, we studied two cases of hypopigmented vitiligo regarding the melanocytes and keratinocytes' changes before and after 7 months of psoralen plus ultraviolet A (PUVA) therapy. Skin biopsies were taken from the vitiliginous lesions before and after 7 months of PUVA therapy and were examined using haematoxylin and eosin and Masson Fontana stains, L-3,4-dihydroxyphenylalanine reaction, immuno-histochemical stains and ultrastructural examination.

Continuous-wave Nd:Yag laser hyperthermia: a successful modality in treatment of basal cell carcinoma.

It was observed that malignant tumor cells are more sensitive than normal cells to heat. Hyperthermia is known to be cytotoxic at temperatures above 41 degrees C and selectively lethal to cancer cells. The aim of the present study was to evaluate the therapeutic efficacy of continuous wave Nd:Yag laser-induced hyperthermia in treatment of basal cell carcinoma (BCC).
