Article Synopsis
  • - The study focused on distinguishing tuberculous lymphadenitis (TBLN) from non-tuberculous lymphadenitis (NTBLN) in adults in Turkiye, analyzing demographic, clinical, and laboratory data from patients with swollen lymph nodes.
  • - A total of 812 patients were studied, revealing that TBLN was the most common diagnosis (53.69%), with higher occurrence in females and those who had elevated erythrocyte sedimentation rate and positive test results for tuberculosis (p < 0.05).
  • - The findings suggest that identifying specific variables can help clinicians improve their diagnosis and treatment strategies for adult lymphadenopathy.

Objective: Pannus overgrowth is a chronic inflammatory process that can cause valve dysfunction and threaten the durability of prosthetic valves. Bileaflet mechanical mitral valve can be implanted in either an anatomical (parallel to the anatomical axis) or nonanatomical (perpendicular or oblique to the anatomical axis) orientation. The effect of the rotational orientation of the bileaflet mechanical mitral valve on excessive pannus enlargement is unknown.

Objective: The lower extremity contains a variety of functional structures therefore re-establishing soft tissue coverage in large-scale injuries is a challenging procedure. Microsurgery has made progress in reducing donor morbidity and achieving a functional and aesthetic appearance in recent years. This study aimed to apply anterolateral thigh (ALT) flap to tissue defects in the lower extremity and to discuss the results.

Background: In this systematic review, we aimed to examine the risk factors and surgical outcomes of gastrointestinal complications using the meta-analysis techniques.

Methods: Studies involving patients with and without gastrointestinal complications after cardiac surgery were electronically searched using the PubMed database, Cochrane Library and Scopus database, between January 2000 and May 2022. Some studies on gastrointestinal complications examined only single gastrointestinal complication (only intestinal ischemia, only gastrointestinal bleeding or only liver failure).

Pelvic kidney is a mostly asymptomatic pathology resulting from failure of the kidneys to superior migration in fetal development. Herein, we report a 47-year-old female patient who presented with intermittent claudication in her right leg at 100 m. Significant stenosis was detected in the right superficial femoral artery and popliteal artery by computed tomography angiography.

Thrombotic and microangiopathic effects have been reported in COVID-19 patients. This study examined the contribution of the hereditary thrombophilia factors Prothrombin (FII) and Factor V Leiden (FVL) genotypes to the severity of COVID-19 disease and the development of thrombosis. This study investigated FII and FVL alleles in a cohort of 9508 patients (2606 male and 6902 female) with thrombophilia.

Objective: Our study aims to compare the clinical results of percutaneous screw fixation and non-vascularized bone grafting with open screw fixation in patients who did not achieve union due to failure in diagnosis and treatment after a scaphoid fracture.

Patients And Methods: Forty-three patients with scaphoid nonunion fractures corresponding to the first three Slade and Dodds classification were divided into two groups. Non-vascularized bone grafting with open reduction and internal fixation (ORIF) was applied to 24 patients in the first group, and 19 patients in the second group were treated with a closed reduction and internal fixation (CRIF) (percutaneous screw fixation).

Purpose: Stanford type A aortic dissection (TAAD) is the most common and fatal type of dissection. An easier-to-use risk stratification may help eliminate bias in patients at high risk of dissection. The age, serum creatinine, and ejection fraction (ACEF) score is a simple risk model developed to predict the mortality risk of elective coronary artery bypass graft surgery.

Background: Coronary artery perforations are one of the most feared, rare, and catastrophic complication of percutaneous coronary intervention. Despite the remarkable increase in coronary angiography and percutaneous coronary intervention, there is no large database that collects coronary artery perforation for the Turkish population. Our study aimed to report our experience over a 10-year period for clinical and angiographic characteristics, management strategies, and outcomes of coronary artery perforation during the percutaneous coronary intervention at different cardiology departments in Turkey.
