The single most important clinically relevant cause of global cerebral ischemia is cardiac arrest. The estimated rate of sudden cardiac arrest is between 40 and 130 cases per 100.000 people per year. Almost 80% of patients initially resuscitated from cardiac arrest remain comatose for more than one hour. One year after cardiac arrest only 10-30% of these patients survive with good neurological outcome. The ability to survive anoxic no-flow states is dramatically increased with protective and preservative hypothermia. The results of clinical studies show a marked neuroprotective effect of mild hypothermia in resuscitation. ⋯ Mild resuscitative hypothermia after cardiac arrest improves neurological outcome and reduces mortality in comatose survivors.

Recent literature data suggest that permanent or reversible hearing loss may occur after general anesthesia. The etiology varies, while hearing loss following middle ear surgery is attributed to exposure to nitrous oxide (N,0). The objective of our study was to measure, using tympanometry, the middle air pressure change caused by nitrous oxide during general anesthesia and to establish its emetogenic effects during the postoperative period. ⋯ Postoperative audiometry findings showed no conductive or sensorineural hearing loss after interventions. Nitrous oxide can be used in general balanced anesthesia with discontinuation 15 to 45 minutes before insertion of the tvmpanic membrane and completion of middle ear surgery.

Hypertrophic pyloric stenosis (HPS) is the most common abdominal surgical condition in newborns and infants, while intussusception is the most frequent problem in children between the ages of 6 months and 2 years. The aim of this study was to show the advantages of ultrasonography in diagnosis of hypertrophic pyloric stenosis and intussusception and also to point out the efficiency of ultrasound guided hydrostatic reduction of childhood intussusception, as a nonoperative therapeutic option. ⋯ Ultrasonography has proved to be a remarkably precise diagnostic modality in diagnosing HPS and intussusception, but also makes nonoperative treatment of intussusceptions possible in extremely high percentage.

[Endonasal endoscopy and computerized tomography in diagnosis of the middle nasal meatus pathology].
Diagnostic nasal endoscopy enables clear visualization of all structures of the middle nasal meatus and of the ostiomeatal complex. It is a primary means for diagnosis of all anatomic variations and other pathogenic factors of the lateral nasal wall, which cannot be diagnosed by using anterior/posterior rhinoscopy. Furthermore, the effects of therapy can be endoscopically controlled and, if necessary, a surgical procedure may be performed. Computed tomography has become the imaging study of choice in the diagnosis and management of sinonasal diseases. It provides detailed information and an unparalleled view of the sinuses, especially the bony anatomy. ⋯ The diagnosis of rhinosinusitis is generally based on clinical grounds. In 1997, the Task Force of Rhinosinusitis developed the major and minor criteria for diagnosing rhinosinusitis. The presence of two major or one major and two minor symptoms is generally sufficient to make a clinical diagnosis of rhinosinusitis. In order to make a specific diagnosis and provide specific treatment, ednonasal endoscopy is the method of choice. In cases with refractory rhinosinusitis, acute rhinosinusitis with complications, or atypical cases requiring confirmation of sinusitis, use of coronal and axial CT is necessary. This article confirms that diagnostic endoscopy of the nose and paranasal cavities with computer tomography of paranasal cavities represent an ideal combination and a widely recognized standard for diagnosis and treatment of nasal and paranasal cavity disorders in many countries.

Understanding the lawful implementations of surgical procedures, such as hysterectomy, raises practical questions concerning legal relations between a doctor and his patient, and consequences of this relationship, which may be legally relevant. The modern legal theory and practice consider doctors and patients to be partners. ⋯ A patient has a right to receive complete information from a physician about the specific nature of a proposed treatment. A physician has an obligation to elucidate and justify, treatment he proposes. Certain codification of all operative procedures may facilitate this task. Codification instructions about procedures, in this case hysterectomy, must include indications for a certain type of hysterectomy (subtotal, total, radical), as well as for the operative technique (abdominal, vaginal, laparoscopic). Patient information brochures should be available in print, and include information about indications and potential risks associated with the proposed surgical procedure. In this way, it is possible to prevent the inconveniences which may arise from insufficient knowledge and information about surgical procedures.
