Subchondral cyst of bone: a case report

This is a report of a subchondral cyst of the entire fibular head in a 24-year-old woman, and a survey of the literature including pathogenesis, histopathology, and management. Subchondral bone cyst in this location seems not to have been reported previously. The treatment was excision of the head of the fibula.

Correlation of arthroscopy with other diagnostic modalities

In our experience arthroscopy proved to be the most reliable method of evaluating internal derangement of the knee. Among 96 patients who underwent arthrotomy, the arthroscopic diagnosis was confirmed in 96 per cent. The combined anteromedial, anterolateral, and posteromedial approaches consistently demonstrated all intraarticular disorders. We found the posterolateral approach of little benefit.

Osteosarcoma complicating Paget's disease of the spine with neurologic complications

An osteosarcoma with neurologic manifestations complicated Paget's disease of the lumbar spine in a 63-year-old man. Initially without demonstrable metastasis, the patient was treated by decompressive laminectomy followed by radiation and adjuvant chemotherapy (COMPADRI-1 regimen). While such treatment may not be curative, there are significant palliative benefits.

Use of centrifugal disk atomizer to produce CdS films

The use of a centrifugal disk atomizer to produce chemically sprayed CdS films is described. The film growth rate has been found to depend on substrate temperature, solution concentration, and feed rate. The films grown on glass substrates have been studied by electron microscopy and x-ray diffraction. A fine-grained wurtzite structure has been obtained.

[Intestinal motility and pattern of biliary acids in healthy children and children with acute and chronic diarrheic syndrome]

Thirteen children between the ages of six months and six years with acute diarrheal syndrome were investigated for Small Bowel Transit Time (SBTT). The results were compared with another study made by our section in which eleven children were studied; seven with chronic non-specific diarrhea and four controls. All the subjects had a double lumen catheter positioned in the small intestine with ports located 1 meter apart. A bolus of 4% P.E.G. was delivered into the stomach and the rate of appearance was monitored at the two collecting ports. Four normal children had a small bowel transit time of 60 min/m; one subject with shigella revealed a small bowel transit time of 30 min. Eight children with acute non-specific diarrhea had a mean of 90. Seven with chronic non-specific diarrhea had a mean of 99 min/m. Four patients with serotype positive E. coli had a mean of 83. In each case where SBTT was delayed there was also an increase in luminal free bile acids. In conclusion, diarrheal syndrome in children may present accelerated or delayed SBTT according to the etiology of each. Children with diarrheal syndrome showed an abnormal bile acid pattern in the duodenum which may represent a bacterial overgrowth and introduce a pathogenic role in the disease.

Treatment of skin irritation around enterostomies with cholestyramine ointment

Eight patients with inflammation of the skin about the cutaneous stoma responded to local application of a 20% cholestyramine ointment in a short period of time. Two children treated with the hydrophilic base (Aquaphor) alone did not respond to treatment. The ileal bile acid patterns of two children with ileostomies were found to be different from that of the control group. Ileostomy patients had a higher concentration for total bile acids and a higher percentage of free bile acids.
