Electroencephalography in primary diagnosis of mild head trauma.

OBJECTIVE: the aim of this study was to compare the clinical examination and EEG examination regarding their relevance in diagnosing cerebral function changes in early head trauma. METHODS: ninety four male patients who suffered from mild head trauma (GCS 13-15) were assigned into two groups. The first group fulfilled at least one sign of cerebral concussion (amnesia, anisocoria, changes of vigilance or vegetative symptoms such as vomiting), the second group did not. EEG examination was performed in both groups. RESULTS: in the first group, more pathologic EEG records were found. These findings showed a statistical significance (p = 0.019). The concussion group showed more focal changes (p = 0.283) and specific changes (p = 0.317), but they were statistically not significant. CONCLUSION: EEG can be used for detecting pathologic unspecific alterations with a high accuracy, but is not useful in specifying the findings for an exact diagnosis.

Serum collagen type VI and XIV and hyaluronic acid as early indicators for altered connective tissue turnover in alcoholic liver disease.

Hepatic fibrosis in alcoholic liver disease often heralds progression to cirrhosis and, therefore, noninvasive parameters are required for early diagnosis and follow-up. Collagens VI and XIV, procollagen-III-N-propeptide, hyaluronic acid, and active transforming growth factor-beta1 (TGF-beta1) were measured in healthy volunteers, patients with alcoholic cirrhosis, and heavy drinkers without cirrhosis. Noncirrhotic alcoholics were assigned to two groups with either normal aspartate aminotransferase or levels > or = 2 normal. Collagens VI and XIV were elevated in all alcoholic patients compared to controls (P < 0.0001, all instances). Procollagen-III-N-propeptide and hyaluronic acid levels were higher in alcoholic patients with elevated liver enzymes and in cirrhotics as compared to controls. Procollagen-III-N-propeptide revealed a significant correlation with serum levels of TGF-beta1 (P < 0.0001). Collagens VI, and XIV, procollagen-III-N-propeptide, and hyaluronic acid appear to be sensitive markers indicating fibrotic transformation in alcoholics. The correlation between procollagen-III-N-propeptide and TGF-beta1 emphasizes its role in hepatic fibrogenesis.

[Lesions of peripheral structures of cadaver fingers caused by Kirschner wires].

Fractures of the hand skeleton are common injuries. These are or are associated with phalangeal fractures. Kirschner wires can be used for osteosynthesis, but can cause lesions of peripheral finger structures. The aim of our study was to record the incidence of lesions in peripheral structures of the fingers caused by retrograde crossed inserted Kirschner wires of 1.0, 1.25, 1.4 and 1.6 mm diameter into the middle and proximal phalanges of the long fingers and the proximal phalanx of the thumb of 120 fresh cadaver hands. We found an increase of insertion attempt frequency and an increasing number of lesions with increasing Kirschner wire diameter. Because of these findings Kirschner wires of 1.0 or 1.25 mm diameter should be preferred to prevent the peripheral functional finger structures.

Forced-air warming maintains intraoperative normothermia better than circulating-water mattresses.

The hypothesis that forced-air warming preserves core temperature better than circulating-water mattresses was tested in: (a) 16 adults undergoing major maxillofacial surgery, including radical node resection and flap reconstruction; (b) 53 adults undergoing hip arthroplasty, having approximately 25% of their body surface area available for warming; (c) 20 infants undergoing minor maxillofacial surgery; and (d) 10 young children undergoing pelvic or femoral osteotomies. Patients having each type of surgery were randomly assigned to forced-air warming (approximately 40 degrees C) or conductive warming using a full-length circulating-water mattress at 40 degrees C. Forced-air warming was applied to the legs of the adults undergoing maxillofacial surgery and to one arm, the shoulders, and the neck in the adults undergoing hip arthroplasty; a U-shaped, tubular forced-air cover was positioned around the pediatric patients. Core temperatures increased in all patients given forced-air warming and decreased or remained constant in those without active warming. Furthermore, we needed to decrease the temperature of the warmer from high to medium (approximately 37 degrees C) in most patients assigned to forced-air warming to prevent hyperthermia. After 15 h of anesthesia, rectal temperatures in the adults undergoing maxillofacial surgery were 3.4 degrees C higher in the forced-air group (P < 0.01). After 4 h of anesthesia, esophageal temperatures had increased 0.8 +/- 0.5 degrees C in the patients warmed with forced-air and decreased 0.8 +/- 0.3 degrees C in those warmed by circulating-water mattresses (P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
