Campomelic dysplasia--an underdiagnosed condition?

Campomelic dysplasia (CD) is a rare skeletal dysplasia. The incidence, reported in the literature, is 0.05-0.09 per 10,000 live births. During the period December 1985-December 1990 there were 18,350 live births with 4 cases of CD at Aker University Hospital in Oslo, Norway. This gives an incidence of CD in our observation period of 2.2 per 10,000. Eliminating our first case, because of Pakistani decent, the total incidence is 1.6 per 10,000 among Norwegian infants which is much higher than the incidence previously mentioned. Perhaps CD is under-reported and a high proportion of patients remain undiagnosed. We present four cases and discuss the incidence.

CT in idiopathic pyogenic myositis of the iliopsoas muscle. A report of 2 cases.

Pyogenic myositis of the iliopsoas muscle may occur as a primary clinical entity of an idiopathic nature, or more commonly secondarily to an adjacent disease process. We report 2 cases of idiopathic pyogenic infection caused by Staphylococcus aureus. This disease entity is rare in temperate climates. CT combined with clinical and biochemical information enabled the correct diagnosis, and appropriate treatment could thus be started.

Hysterosalpingography with Amipaque.

The authors report their initial experience with Amipaque (metrizamide) in hysterosalpingography. Amipaque was compared to Isopaque Cerebral in 37 patients, using a double-blind design. Excellent radiographs were obtained with both agents. No statistically significant difference in discomfort and pain was found up to 24 hours after the procedure. However, the aftereffects indicate that Amipaque might be less irritating to the pelvic peritoneal cavity.

The risk of deep-vein thrombosis after operations on a bloodless lower limb. A venographic study.

In 17% of 40 patients undergoing operation in a bloodless field on the lower limb, thrombosis was diagnosed phlebographically. Phlebography was performed between the second and eighth postoperative day. The incidence of thrombosis in this series was relatively low, considering other reports on postoperative thrombosis and the theoretical dangers of thrombosis involved in the use of a tourniquet. Factors which could explain the relatively low frequency of postoperative thrombosis are discussed.

Effective renal plasma flow (ERPF) of the individual kidney and renal venous renin activity (RVRA) determined simultaneoulsy before and after the administration of dihydralazine in renovascular hypertension.

Effective renal plasma flow (ERPF) and renal venous renin activity (RVRA) were determined for the two kidneys separately before and after intravenous administration of dihydralazine in 50 cases of suspected unilateral renovascular hypertension. A ratio above 1.4 between the ERPFs of the two kidneys and an RVRA ratio above 1.5 were used as signs of lateralization. The two procedures showed agreement about presence or absence of lateralization in 36 cases before and 44 after dihydralazine administration. Eleven patients underwent surgery. ERPF and the changes in ERPF induced by dihydralazine gave important prognostic and preoperative information. Data on renin release rates are presented.

Radiologic evaluation of urolithiasis.

Interobserver variations between three radiologists with different backgrounds (duration of practice, and departments) were studied in connection with the diagnosing of urolithiasis. Films from 152 consecutive patients (examined with conventional abdominal films, urography/tomography) were analyzed independently. With respect to the number of patients with or without calculi there was agreement between the three observers in 129 of the 152 cases, which was taken to represent very good agreement beyond chance. The total number of stones was interpreted as 832, 460 and 570 respectively, and the median stone size as 6, 9 and 11 mm2. There was a fair interobserver agreement rate regarding whether stones were localized to the renal parenchyma or calyces, and whether stenosis/stricture or hydronephrosis was present. Tomography appeared to reduce the interobserver variability significantly. Adequate bowel cleaning, oblique projections, and lack of clinical information apparently did not influence the agreement rate. It was concluded that such interobserver variations are factors of importance in the reliability of the radiologic evaluation of urolithiasis.
