Aim: To analyze and to compare the factors that influence the recurrence of chronic subdural hematoma (CSDH) among patients treated with subdural non-suction-assisted passive drainage, subgaleal suction-assisted active drainage, and without drainage.
Material And Methods: We retrospectively evaluated 87 surgical patients with a diagnosis of CSDH treated between 2007 and 2018 using patient records from the neurosurgery archive of our faculty. The patients were divided into three groups: drainfree group (group A), subdural passive drainage group (group B), and subgaleal active drainage group (group C). Recurrence was defined as an increase in hematoma volume on imaging and persistence of the patient?s symptoms.
Results: Patients with double-membrane CSDH exhibited higher recurrence rates (p=0.043) and those with low-density CSDH exhibited lower recurrence rates (p=0.015) compared to the other patients. No relationship was found between the number of burr holes made and CSDH recurrence (p=0.177). Group C showed the lowest recurrence rate (13.3%), but the differences between groups were not statistically significant.
Conclusion: Hematoma density, membrane type, postoperative Glasgow Outcome Scale scores, and postoperative drainage time were found to be statistically significant predictors of recurrence. Burr-hole craniotomy with subgaleal active drainage is a safe and effective method for preventing CSDH recurrence and carries a reduced risk of parenchymal injury.

The soil in reclaimed shale gas sites is compacted and suffers from issues like poor drainage, drought conditions, and nutrient deficiency, posing challenges for agricultural production. In this study, rare earth tailings were incorporated into biochar at different mass ratios (rare earth tailings: biochar = 1:1, 1:2, 1:3, 1:4). Subsequently, a series of rare earth tailings-doped biochar materials (REE-BC) were prepared by calcination at 700°C.

Marine ecosystems, particularly estuaries, are increasingly threatened by anthropogenic pressures. The Odiel Estuary has suffered severe contamination from acid mine drainage and industrial activities. Since 1986, mitigation efforts have been implemented, yet their long-term ecological effectiveness remains under-evaluated.

Hypervirulent is a recently identified pathotype characterized by high virulence and rapid dissemination. It is associated with invasive infections at multiple anatomical sites, including liver abscesses, necrotizing fasciitis, meningitis, myositis, and endophthalmitis. It has emerged as a significant threat to public health due to its aggressive clinical course and high mortality rate.

Background And Aim: Hospital effluents are a major source of environmental contaminants, harboring pathogenic bacteria, toxic trace metals, and high organic loads. This study aimed to evaluate the bacteriological and physicochemical profiles of wastewater discharged from three coastal hospitals in Oran, Algeria, and to assess the associated public and livestock health risks under the One Health approach.
Materials And Methods: A cross-sectional study was conducted from January 2023 to February 2024, involving monthly sampling at three hospitals and one drainage collector.

Introduction: Liver transplantation for polycystic liver disease (PLD) poses significant intraoperative risks due to the presence of a massively enlarged liver. We report a rare case of intraoperative pneumothorax and pneumatocele formation during total hepatectomy, which was successfully managed with a non-operative approach.
Case Presentation: A female patient in her 40s with a history of autosomal dominant polycystic kidney disease presented with progressive liver cyst enlargement (Gigot type III, Qian classification Grade 4), which led to decreased activities of daily living and intracystic hemorrhage.
