Desmoid tumors or fibromatoses comprise a number of benign fibrous proliferative lesions that have local infiltrative growth and tendency to recur after incomplete excision. They never metastasize. The authors present a 31-year-old woman who, due to epigastric pain and palpable mass detected on presentation, underwent the excision of firm tumorous mass, 210 x 140 x 115 mm in diameter, from the lesser sac. ⋯ The recovery was uneventful. The histological examination verified typical desmoid tumor. Twelve years after surgery, the patient remained symptom-free with no signs of recurrence.

Historical Article
[The first film presentation of REM sleep behavior disorder precedes its scientific debut by 35 years].
The perplexing and tantalizing disease of rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by peculiar, potentially dangerous behavior during REM sleep. It was described both in animals and humans. RBD in mammals was first described by Jouvet and Delorme in 1965, based on an experimental model induced by lesion in pontine region of cats. ⋯ AC KNOWLEDGEMENT TheauthorsthankDr. NikolaTrajanovid, ABSM, FAASM (Canada) for valuable suggestions, and Dr. Carlos Schenck from the Minnesota Regional Sleep Disorders Center (USA) for reading the manuscript.

Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. ⋯ Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

The basic ethical principles in science are internationally recognised in all disciplines of science. The first among these is honesty--both towards oneself and towards others. The betrayal of this principle can be seen as deviant behaviour, which may result in the most serious violation of the high ethical standards of science--scientific fraud. ⋯ In this article, several high profile cases of scientific fraud--involving falsification, fabrication of data, and plagiarism--are described. The damaging effect they had on both science and the scientific community led to the codification of the concept of Good Scientific Practice (GSP)--an international quality standard for designing, conducting, recording, and reporting research. The concept of GSP sets internationally valid benchmarks for quality assurance, and also provides safeguards against scientific dishonesty and fraud.

Randomized Controlled Trial Comparative Study
[Reverse Trendelenburg's position vs. supine-horizontal position for induction of general anesthesia in obese neurosurgical patients].
The induction of general endotracheal anesthesia (GETA) is associated with variable period of apnea. Obese patients have reduced oxygen supply during period of apnea. Hypoxemia and subsequent hypercarbia, during period of apnea, are strong stimuli of cerebral blood flow and intracranial pressure increase. ⋯ 30 degree reverse Trendelenburg's position provides longer SAP when compared with horizontal-supine positions. This extra time may preclude adverse sequelae resulting from hypoxemia during induction of obese neurosurgical patients.
