The thoracodorsal artery perforator flap in the treatment of axillary hidradenitis suppurativa: effect on preservation of arm abduction.

Unlabelled: Hidradenitis suppurativa is a chronic, recurrent inflammatory disease of the skin characterized by abscesses and scars. The axillary region is predominantly affected, leading to limited mobility of the arm due to scar retraction. This prospective study aimed to analyze the surgical treatment of severe lesions of axillary hidradenitis suppurativa by using the thoracodorsal artery perforator flap while focusing on the preservation of arm abduction.

Mammalian target of rapamycin expression and laryngeal squamous cell carcinoma prognosis: novel preliminary evidence.

Aims: The mammalian target of rapamycin (mTOR) has a key role in regulating cancer cell proliferation, apoptosis, cell migration, and angiogenesis. The aim of this study was to assess the relationships between mTOR and clinicopathological and prognostic parameters in laryngeal squamous cell carcinoma (SCC).

Methods And Results: Mammalian target of rapamycin expression was determined in 103 consecutive operable laryngeal SCCs.

A higher CD105-assessed microvessel density and worse prognosis in elderly patients with laryngeal carcinoma.

Objectives: To ascertain the prognostic role of endoglin (CD105)-assessed microvessel density (MVD) in patients older than 65 years with laryngeal squamous cell carcinoma (LSCC), and whether this MVD differed in the elderly patients from younger adult controls.

Design: Retrospective clinicopathologic investigation.

Setting: Academic tertiary referral center.

Anatomicosurgical segments of the human pancreas.

Two anatomicosurgical segments of the human pancreas were recognized in 30 corrosion casts after injection of the pancreatic arteries thus confirming prior anatomico-surgical studies. The right (cephalocervical) and the left (corporocaudate) segments of the pancreas are separated by a paucivascular area. They are linked by the pancreatic duct and often by a single, small artery, which may be a branch of the gastroduodenal, gastroepiploic (gastromental), or dorsal pancreatic artery.

Anatomic characteristics of the pancreatic arteries. Radiologic observations and their clinical significance.

Major complications of operations that remove or transplant a portion of the pancreas appear related to the arterial blood supply. Hemorrhage is a result of inadequate control of the appropriate principal arteries, and ischemia and its consequences occur when the arterial blood supply to portions of preserved pancreas has been inadvertently interrupted. This radiographic study of the principal arteries of the pancreas demonstrates that these vessels may be visualized and their origin determined in the vast majority of cases.
