According to an American College of Chest Physicians consensus statement published in 2001, it is recommended that chest tubes should be used for the drainage of primary spontaneous pneumothoraces. However, more recent expert opinions and guidelines suggest that simple aspiration is increasingly recognized as an acceptable alternative treatment. Studies have shown that the success rates and recurrence rates of simple aspiration are comparable to, if not more favorable than, those of chest tube drainage and small-bore catheter aspiration. Simple aspiration is the least invasive modality and it has economic cost-saving benefits, particularly with respect to admission rates and hospital length of stay. Its complication rate is low. However, a larger size of pneumothorax seems to be associated with increased likelihood of failure of simple aspiration. The author reviews the available evidence relating to the use of simple aspiration as a modality for treating primary spontaneous pneumothorax.

Background And Objectives: Distal biliary strictures (DBSs) can be caused by various malignancies, making accurate and early diagnosis crucial. Histopathology is the gold standard for diagnosis, with several methods available for tissue sampling. This study evaluates the performance of EUS-guided fine-needle aspiration (EUS-FNA) cytologic smears and histopathology in diagnosing suspected malignant DBSs.

Integrated Management of Childhood Illness (IMCI) is a strategy that aims to standardise clinical assessment and treatment of sick children. In this article, we examine the aspirations and unfolding of introducing a revised IMCI strategy in Bangladesh. We carried out ethnographic fieldwork among project implementors and in IMCI health service delivery settings in Kushtia district, including 36 semi-structured interviews with policymakers, programmers and IMCI service providers.

Spinal cord trauma leads to the destruction of the highly organized cytoarchitecture that carries information along the axis of the spinal column. Currently, there are no clinically accepted strategies that can help regenerate severed axons after spinal cord injury (SCI). Hydrogels are soft biomaterials with high water content that are widely used as scaffolds to interface with the central nervous system (CNS).

Objective: To compare the clinical outcomes of ultrasonography-guided aspiration and sclerotherapy and laparoscopic deroofing for the treatment of simple renal cysts in children, providing evidence for clinical decision-making in the management of pediatric renal cysts.
Methods: A total of 49 patients with simple renal cysts were divided into two groups based on the treatment method: 29 patients (group 1) underwent laparoscopic deroofing, 20 patients (group 2) underwent ultrasonography-guided aspiration and sclerotherapy. The clinical efficacy differences between the two groups were compared.
