Intestinal neurofibromatosis. Multiple complications in a single case.
The use of radionuclide gastrointestinal scanning with 99mTc sulfur colloid, supplementing angiography, is described in the diagnosis of the source of bleeding in a 60-year-old woman with neurofibromatosis. These two procedures succeeded in locating the origin of bleeding from neurofibroma in the jejunum, which was corrected by surgery. To our knowledge, this case report is the first description of a patient with neurofibromatosis, with all the reported gastrointestinal symptoms: intermittent abdominal pains, palpable abdominal mass, gastrointestinal bleeding and small bowel obstruction.

Local penetration of gentamicin into the femoral cortex of rats.
To investigate the extent of local penetration of antibiotic into the bone, a single dose of 10 mg/kg gentamicin sulphate was injected over the midshaft of the left femur in 12 young and 14 old rats. In some of the rats the injected gentamicin was dissolved in saline while in the others it was dissolved in dimethylsulphoxide (DMSO). Up to 120 minutes after the injection gentamicin concentrations were measured by the fluoroimmunoassay method in the serum, cortex and spongiosa of both femurs. In young rats gentamicin was shown to have penetrated directly into the bone and its presence was limited to the femoral cortex. In the old rats, on the other hand hematogenic was found to be the antibiotic spread in the femurs. No significant difference was observed between DMSO and saline as solvents in facilitating gentamicin penetration into the bone or capillaries in either age group.

Residual shortening after osteotomy for Perthes' disease. A comparative study.
The residual shortening of the affected limbs in 55 patients treated by subtrochanteric varus derotation osteotomy was compared with that in 71 patients treated with weight-relieving calipers. When last examined, 43 of the former group and 47 of the latter had reached complete or near-complete skeletal maturity. The average follow-up was 9.1 years in the osteotomised patients and 5.25 years in the conservatively treated group. The average residual shortening (0.9 cm) was identical in both groups. In most patients the initial shortening caused by the osteotomy gradually corrected as, over a period of several years, the postosteotomy angle gradually became less varus. Any residual shortening depended principally on the severity of inhibition of endochondral ossification at the proximal femoral growth plate. Less residual shortening was seen in children who were under seven years of age at the onset of symptoms (under eight at operation) in whom the open-wedge technique of osteotomy was employed and who had good anatomical results.

Abduction-traction injury of the knee.
Disruption of the major ligaments of the knee was seen in six young men, five parachutists and a house painter, after what we have termed abduction-traction injury. This unusual complaint results from the application of a sudden block to the ankle while falling head first, leading to traction and abduction of the knee. All the patients underwent operations, generally with unsatisfactory results. At operation tears of the anterior cruciate ligament, medial collateral ligament and posterior oblique ligament were seen in each case; in four patients the posterior capsule and in three the posterior cruciate ligament also were torn. In one patient the lateral collateral ligament was torn and the lateral meniscotibial ligament was avulsed. The compression component is absent in this type of injury and consequently the menisci and the osteochondral surfaces of the tibia and femur remained intact in each case.

Multiple exostoses-mental retardation syndrome. A case report and review of the literature.
A girl seven years ten months of age with multiple exostoses-mental retardation (MEMR) syndrome was treated by bilateral supracondylar osteotomies at the age of six years 11 months for correction of severe genu valgum. The case is the 14th to be described in the English-language literature and seems to be the first on record in which the deformity was corrected by surgery. Typical findings in this syndrome include unusual facial features with bulbous nose, sparse scalp hair, large ears, microcephaly, mental retardation, cone-shaped epiphyses of the digital phalanges, and multiple exostoses. Each of these features may also appear in other constitutional and genetic disorders, and only their combination points to a definite diagnosis of MEMR syndrome. Other features, e.g., joint laxity and loose skin, are transient and may cause some confusion in diagnosis, sometimes leading to a mistaken diagnosis of cerebral palsy or Ehlers-Danlos syndrome. Thus, care must be taken in consecutive examinations to seek and identify each of the above mentioned typical features of the disorder.

Simultaneous changes in striatal dopamine, serotonin, and metabolites after withdrawal seizures in rats from dependence on alcohol.
Ethanol dependence was achieved in male, Long-Evans rats after 8 days on a balanced liquid diet that supplied 4.5% ethanol. After 1-h access to a solution of 10% ethanol (95%)/5% sucrose, the rats were deprived of food, water, and ethanol for 9 h. Following 30-s key jingling, about 80% of the animals exposed to ethanol experienced tonic-clonic seizures. Neurochemical analyses of striatal tissues revealed a significant (p < 0.05) increase in dopamine (DA) and a significant decrease in serotonin (5-HT) in the ethanol-exposed rats that had seizures compared to control rats. Homovanillic acid concentrations of the ethanol-treated rats with seizures were significantly higher than the levels found in ethanol-treated animals that had experienced no seizures. Daily average ethanol intake of the rats that had seizures vs. those that did not was almost the same at 16 g/kg/day. The findings indicate that rats experiencing ethanol withdrawal-induced seizures manifest opposite alterations in dopaminergic and serotoninergic activity compared to controls. The present results do not reveal if the striatal changes are caused by ethanol rather than by the seizures.
