The generalizability of artificial intelligence (AI) models is a major issue in the field of AI applications. Therefore, we aimed to overcome the generalizability problem of an AI model developed for a particular center for pneumothorax detection using a small dataset for external validation. Chest radiographs of patients diagnosed with pneumothorax (n = 648) and those without pneumothorax (n = 650) who visited the Ankara University Faculty of Medicine (AUFM; center 1) were obtained.

Dis Esophagus
November 2017
Unconsciously caustic ingestion is one of the most common causes of serious esophageal strictures in children. The aim of this study is to determine the efficiency of polaprezinc in preventing stricture formation after corrosive esophageal burns (CEB); this was the first time it has been used to treat experimental CEB in rats. Twenty-four rats were divided into four groups, three of which received CEB by the instillation of 1 mL of 10% NaOH solution into their isolated esophageal segments for three minutes.

- Rectal duplication (RD) cysts are rare congenital issues, often identified by an extra opening in the perineum, and they typically occur without accompanying anorectal malformations (ARM).
- Two cases are highlighted: a 3-month-old baby with a specific anal dimple opening and a 2-year-old girl with more complex symptoms, including other syndromes.
- During surgery, both patients had their unusual openings linked to retrorectal cysts, emphasizing the need for careful examination and treatment of complex malformations.
Rat tail revascularization model for advanced microsurgery training and research.
J Reconstr Microsurg
September 2011
We describe a time-saving microsurgical exercise for continuing microsurgical training and research. The rat tail replantation model was simplified by excluding bone detachment. Rats were divided into two groups: devascularization only ( N = 3) and revascularization after devascularization ( N = 7).

The outcomes after stent placement were also compared with those after balloon dilatation and cutting balloon dilatation performed after stricture development. Groups were compared with regard to stricture development and weight loss.
