Intravenous cholegraphy and ultrasonography in examination of orally nonfilled gallbladders.

The efficacy of intravenous cholegraphy (IVC) and gray-scale ultrasonography (US) in detecting the presence or absence of gallstones was evaluated in 54 patients with orally nonfilled gallbladders. The IVC finding was diagnostic in 26 cases (48%), of which 19 were normal and 7 had gallstones. The respective figures by US were 48 (89%), 18 and 30. In 3 cases only IVC was diagnostic and in 25 cases only US. US was considered to be the method of choice for the secondary examination of an orally nonfilled gallbladder. IVC is justified as a secondary examination if US is not available and is indicated as the tertiary examination if US fails or if a clinical suspicion of gallbladder disease remains after a normal US finding.

Venous drainage of the femoral neck in various stages of activity in Perthes' disease.

The venous drainage of the femoral neck in 73 children with Perthes' disease was analyzed from intraosseous venography films. 55 contralater symptomless hips were used as controls. In active stages of Perthes' disease, i.e. initial and fragmentation stage, the venous drainage was pathological in 46/55 hips (82%). In the restitution stage the finding was pathological in 7/18 (39%) and in healed Perthes' the venous drainage was normal in all six cases. Two out of the 55 symptomless hips showed pathological venous drainage. The disturbances in the venous drainage of the femoral neck seem to correlate with the stage of activity of Perthes' disease. Along with clinical and radiological signs of restitution the venous drainage seems to return to normal.

The diagnostic accuracy of gray-scale ultrasonography compared with ERP and arteriography in the detection of pancreatic carcinoma.

Forty patients who underwent ultrasound, endoscopic retrograde pancreatography (ERP), and selective arteriography examinations and who had a finding of or were suspected of having pancreatic carcinoma in one or several of these examinations form the basis of the study. Nineteen pancreatic carcinomas were verified at operation. Eighteen of these could be detected with ERP, 18 with arteriography, and 15 with sonography. ERP had no, arteriography one and sonography one false-negative finding. All methods had difficulties in distinguishing carcinoma from other pancreatic diseases, and therefore there were many false-positive findings.

Gray scale ultrasound signs of gallbladder stones: clinical and experimental study.

200 patients with radiologically detected gallbladder stones were examined with gray scale ultrasound. Nine different ultrasound signs caused by the stones were found. A physical and chemical analysis of the gallstones of 33 patients from different image groups was performed. Viscosity of the bile and the thickness of the gallbladder wall were measured. Phantom experiments were performed and four different ultrasound signs were found but there was no significant correlation between these and the physicochemical properties of the gallstones.

Comparison of ultrasound and roentgen examination of biliary tract.

The relative merits of gray-scale ultrasound and roentgen examinations of biliary tract diseases have been compared. Sonography was able to give a definite diagnosis in 74 of 95 roentgenologically unclear cases, and roentgen examination gave a diagnosis in 70 out of 105 cases unclear at sonography.

Lymphatic abnormalities in Noonan's syndrome.

Five boys who had Noonan's syndrome and lymphatic abnormalities are reported. The youngest boy had clinical lymphoedema and the other four showed dermal backflow after interdigital injection of Patent Blue indicating impairment of flow along the superficial lymphatics. One boy had severe bilateral chylothorax. The lymphographic findings in four of these boys are reported. Patients with the Noonan syndrome frequently have oedema of the hands and feet at birth, which decreases during the first years of life [10]. It has been demonstrated by lymphography that similar peripheral oedema in patients with the Turner's syndrome is due to lymphatic hypoplasia [1, 3]. We report certain lymphatic abnormalities diagnosed by lymphography in four out of five patients with Noonan's syndrome.

General lymphangiomatosis in a child.

The lymphographic findings in a 4 year old girl with general lymphangiomatosis are presented. The number of iliac and lumbar lymphatics had increased markedly and the lymph nodes were enlarged with very loose structure and with contrast medium distributed in scattered droplets and filiform channels.

Neonatal polycythemia and chest roentgenograms.

Chest roentgenograms of 34 newborns with a hematocrit of 75 or more at the age of 12 hours were studied. An analysis was made of the findings during the first four days of life and the results were compared with those of 18 newborns with a hematocrit of 65 or less. The cardiothoracic ratio (CTR) was found to be greater in the polycythemic infants than in the non-polycythemic infants, and greatest of all in infants with symptomatic polycythemia. Prominent pulmonary vascularity and pulmonary hyperaeration were seen more often in polycythemic newborns than in non-polycythemic infants. Eleven infants in the polycythemic group and three in the non-polycythemic group had some symptoms or signs.

The effect of intertrochanteric osteotomy on the venous drainage of the femoral neck in Perthes' disease.

Intraosseous femoral neck venography was performed both pre- and postoperatively on 30 patients with Perthes' disease. At the time of the operation (osteotomy) and the preoperative venographies, the disease was in the initial stage in 16 patients, in the fragmentation stage in eight patients and in the restitution stage in six patients. As shown previously the venous drainage of the femoral neck preoperatively, in the initial and fragmentation stages of the disease, was different from the venous pattern of the healthy (control) hips in every case, indicating an obstruction of the venous flow. 4-15 months after the osteotomies this venous obstruction had disappeared completely or almost completely in most cases. This normalization happened sooner than expected on the basis of our findings with conservatively-treated patients.
