Opportunistic fungal infections (OFIs) are common among human immunodeficiency virus (HIV) -positive patients, especially in those with delayed diagnosis and treatment. Patients with severe HIV/AIDS with clusters of differentiation 4 (CD4) counts less than 100 are significantly prone to develop multiple OFIs. In the current study, we present a case of co-infection of pulmonary aspergillosis and cryptococcal meningitis in a late-diagnosed HIV patient with a low CD4 count.

Shwannomas are rare benign tumours especially in tracheal. A 16-year-old male presented with a chronic cough, and a thoracic CT scan revealed a pedunculated tumour measuring approximately 11 × 13 mm in size, located 22 mm away from the main carina. Tissue sample was obtained via rigid bronchoscopy and cryobiopsy, and the pathological analysis confirmed the diagnosis of a benign nerve sheath tumour consistent with schwannoma.

Article Synopsis
  • - This study examines the risk of spontaneous pneumothorax in COVID-19 patients, focusing on demographic, clinical, and radiological data, along with survival predictors from a sample of 67 hospitalized cases from December 2021 to March 2022.
  • - Key findings indicate that pneumothorax was most commonly found in the left or right lung, with symptoms including dyspnea, cough, chest pain, and hemoptysis; treatment predominantly involved chest drains, with a 50-day mortality rate of 52.2%.
  • - The research highlights that patients with pleural effusion or pulmonary bullae experience lower survival rates, suggesting the need for further studies to explore the relationship between COVID-19 and pneum

The dynamic mass loss of ice sheets constitutes one of the biggest uncertainties in projections of ice-sheet evolution. One central, understudied aspect of ice flow is how the bulk orientation of the crystal orientation fabric translates to the mechanical anisotropy of ice. Here we show the spatial distribution of the depth-averaged horizontal anisotropy and corresponding directional flow-enhancement factors covering a large area of the Northeast Greenland Ice Stream onset.

Article Synopsis
  • Fibrous dysplasia is a slow-growing bone tumor resulting from incomplete bone maturation, typically found incidentally through imaging and best evaluated with CT scans, which show ground-glass lesions with reactive bone.
  • A case study highlights a 52-year-old man with a large chest wall tumor from the ribs, which was surgically removed along with some surrounding ribs and reconstructed; pathology showed spindle cells and confirmed clean margins.
  • While primary rib tumors are rare, fibrous dysplasia is even rarer, usually asymptomatic, and can be effectively treated with early diagnosis and surgery since the risk of malignant transformation is low.

Purpose: In many cases, pleurodesis is the only treatment available for the treatment of malignant pleural effusion (MPE), and in the case of excessive daily pleural effusion, its therapeutic effect may be reduced. In this study, we intended to investigate the therapeutic effects and safety of octreotide in patients with MPE undergoing pleurodesis with talc powder.

Methods: This study was a single-center, placebo-controlled, and triple-blind, randomized trial designed to investigate the therapeutic effects and safety of octreotide in patients with MPE in Tehran, Iran, from March 2020 to March 2021.

Background: It has been difficult to perform tracheal allotransplantation without immunosuppression. To determine whether decellularized trachea can be used in tracheal replacement, we evaluated the viability of decellularized tracheal allografts in a rabbit model of immunosuppressant-free transplantation.

Method: Half allograft (Group 1, n = 7) was harvested from adult New Zealand white rabbits, subjected to a detergent-enzymatic method (containing sodium deoxycholate/DNase lavations) of decellularization for as many cycles as needed, and the other half was stored in phosphate-buffered saline at 4°C as a control (Group 2, n = 7).
