Spitzoid melanoma of the finger: a case report.

Background: Melanoma is the most malignant skin tumor, with a high metastatic potential. Spitzoid melanoma is a subtype of melanoma requiring rapid management and extensive tumor resection. We have set the goal to recognize anatomical peculiarities and difficulties diagnoses posed by this type of tumor, as well as to recognize the management modalities, especially the surgical one, of malignant spitzoid melanoma.

Critical Preoperative Hemoglobin Value to Predict Anemia-Related Complications After Cardiac Surgery.

Objectives: Preoperative anemia is frequent in patients undergoing cardiac surgery and is associated with increased postoperative complications. The purpose of this observational study was to estimate the critical preoperative hemoglobin threshold associated with the occurrence of complications after cardiac surgery.

Design: A retrospective observational cohort study.

[Retrospective study of 50 cases of tibial pilon fractures in adults at the Department of Orthopedics of the University Hospital Center Habib Bourguiba, Sfax, Tunisia].

Tibial pilon fractures are polymorphic fractures posing therapeutic and prognostic challenges. The purpose of this study is to examine the epidemiological profile of these fractures and to assess our findings from an anatomical and functional point of view. We collected data fom 50 medical records of patients treated for tibial pilon fractures and monitored over the period 2004-2013 at the Orthopedic-Trauma Department of the Habib Bourguiba University Hospital in Sfax.

Infection of a tophaceous nodule of the wirst and hand.

Tophaceous gout occurs years after recurrent attacks of acute inflammatory arthritis. The urate deposits are incriminated in the inflammatory process; however, their infection is exceptional. We report the observation of an infected gouty tophus of the pinky and the wrist of a 40-year-old man, presented as an excruciating inflammatory pain with buff-yellow swelling of the fifth right finger and wrist in a febrile context.

Scurvy: When it is a Forgotten Illness the Surgery Makes the Diagnosis.

Background: Unlike most of animal species, human beings lack the enzymatic process for the conversion of glucose to ascorbic acid (vitaminC), and therefore getting the vitamin from food sources is essential. The association of the various signs caused by a deficiency of vitamin C is called scurvy or Barlow's disease, an easily treatable disease but can be fatal. It is rare in the developed countries and even economically underdeveloped societies in which the basic diet is already rich in ascorbate.

Safety and efficiency of ultrasound-guided intermediate cervical plexus block for carotid surgery.

Objective: Since stroke and myocardial ischaemia are major causes of perioperative morbidity and mortality associated with carotid endarterectomy, monitoring the brain and ensuring the best haemodynamic stability are important goals of the management. As regional anaesthesia was reported to improve haemodynamic stability during carotid endarterectomy (CEA), we conducted a prospective observational study on the efficacy and safety of ultrasound-guided intermediate cervical plexus blocks (CPB), with early (immediate postoperative) and mid-term (day 30) outcomes in awake patients undergoing CEA.

Methods: After the ethics committee approval, 50 patients undergoing a carotid endarterectomy with CPB from April 2011 to May 2013 were included.

[Sedative practice in intensive care units results of a Maghrebian survey].

Objectives: sedation is central to the management of intensive care patients. The aim of this study was to establish the current sedation practice in Maghrebian intensive care units (ICUs). The use of sedation policies with or without a written protocol, the use of scoring systems, the influence of costs on drug choice, the most common drugs for sedation and the use of neuromuscular blocking agents.
