Aim: The aim of the study was to compare the healing and osseous regeneration of mandibular third molar extraction sockets with and without platelet-rich plasma (PRP) with the evaluation of clinical objectives such as pain, swelling, trismus, soft tissue healing, pocket depth distal to second molar and radiological evaluation of the bony density in the postextracted third molar socket.
Materials And Methods: In this prospective study, 100 patients were selected by the random sampling method from the outpatient department of oral and maxillofacial surgery in the year 2016-2017. Patients were equally allocated into intervention (transalveolar extraction followed by PRP placement) and nonintervention (transalveolar extraction without PRP placement) group as group I and group II, respectively, and evaluation parameters were considered accordingly. The statistical analysis was done using SPSS (Statistical Package for Social Sciences) Version 15.0 (IBM, USA) statistical analysis software.
Results: The pain score of patients of group I (non-PRP) was found to be higher as compared to group II (with PRP). Mean trismus of patients of group II was found to be higher than that of group I at postoperative day 7, but this difference was not found to be statistically significant. Swelling at T-Sn (Tragus-Subnasale) and T-Pog (Tragus-Pogonion) was higher among patients of group I as compared to group II. Healing in group II was two to three times faster than group I. Healing among patients of group I and group II was found to be statistically significant. The mean pocket depth of patients of group I was found to be significantly higher than that of group II at follow-up of 1 and 2 months. The bone density of patients of group II was found to be significantly higher than that of group I at 3 months and 6 months follow-up.
Conclusion: The procedure of PRP preparation is simple and cost-effective, and can be prepared at the point of care. It had a significant impact on the postoperative healing of the third molar socket.
Clinical Significance: The use of PRP application increases the bone density, healing process, and improvement in the pain and swelling, and there was a definite reduction in trismus and periodontal probing depth after the impacted mandibular wisdom teeth extraction.

Background: Neuromuscular disorders (NMDs) constitute a heterogeneous group of disorders that affect motor neurons, neuromuscular junctions, and muscle fibers, resulting in symptoms such as muscle weakness, fatigue, and reduced mobility. These conditions significantly affect patients' quality of life and impose a substantial burden on caregivers. Spinal muscular atrophy (SMA) is a relatively common NMD in children that presents in various types with varying degrees of severity.

Background: While recent randomized controlled trials have demonstrated that sublobar resection is non-inferior to lobectomy, the comparative efficacy of these procedures remains uncertain for early-stage non-small cell lung cancer (NSCLC; ≤ 3 cm) exhibiting invasive features postoperatively, such as visceral pleural invasion (VPI) or spread through air spaces (STAS).
Materials And Methods: To identify eligible studies, a comprehensive search of PubMed, Embase, MEDLINE, the Cochrane Library, and Web of Science was conducted through 25 July 2024. Studies were screened according to predefined criteria in accordance with PRISMA guidelines.
Determining the optimal antibiotic duration for skin and soft tissue infections.

Purpose Of Review: Optimal duration of therapy in SSTIs - a heterogeneous group of infections - remains unknown. The advances in knowledge of antibiotic duration of treatment in selected SSTIs that can impact clinical practice and published in the last 18 months are reviewed.
Recent Findings: Recent evidence indicates that few patients receive guideline concordant empiric antibiotics and appropriate duration in the United States, although this likely can be extrapolated to other countries.
Hyperbaric Oxygen Therapy (HBOT) for Management of Complex Regional Pain Syndrome (CRPS).

Objectives: Complex regional pain syndrome remains a challenging condition characterized by severe, persistent pain and a variety of inflammatory and trophic symptoms. This study aimed to analyze the current literature to evaluate hyperbaric oxygen therapy (HBOT)'s efficacy in treating complex regional pain syndrome (CRPS), focusing on both sympathetically-maintained pain (SMP) and sympathetically-independent pain (SIP) subtypes.
Methods: A comprehensive literature search was conducted in PubMed Clinical Queries using the MeSH term "Complex Regional Pain Syndromes" OR the keyword "CRPS" AND "Hyperbaric Oxygen Therapy" OR the keyword "HBOT".

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.
