The validity of information on "race" and "Hispanic ethnicity" in California birth certificate data.

OBJECTIVE: To evaluate the validity of racial/ethnic information in California birth certificate data. DATA SOURCES: Computerized birth certificate data and postpartum interviews with California mothers. STUDY DESIGN AND DATA COLLECTION: Birth certificates were matched with face-to-face structured postpartum interviews with 7,428 mothers to compare racial/ethnic information between the two data sources. Interviews were conducted in Spanish or English during delivery stays at 16 California hospitals, 1994-1995. PRINCIPAL FINDINGS: The sensitivity of racial/ethnic classification in birth certificate data was very high (94 percent to 99 percent) for African Americans, Asians/Pacific Islanders, Europeans/Middle Easterners, and Latinas (Hispanics). For Native Americans, however, the sensitivity was only 54 percent. The positive predictive value of birth certificate classification of race/ethnicity was high for all racial/ethnic groups (96 percent to 97 percent). CONCLUSIONS: Despite limited training of birth clerks, the maternal racial/ethnic information in California birth certificate data appears to be a valid measure of self-identified race and Hispanic ethnicity for groups other than Native Americans.

[The development and x-ray morphology of amiodarone pneumopathy].

Besides general extracardiac physical side effects, the antiarrhythmic amiodarone hydrochloride gives rise to morphologically manifest organ changes. Pneumopathy has been reported in up to 8% of the patients treated with this preparation. Radiologically and histologically, the clinical picture can resemble that of exogenous allergic alveolitis. When the course is protracted there is interstitial fibrotic degeneration of the pulmonary parenchyma with a corresponding morphological correlate in the X-ray. The extent to which the changes observed result from dose-dependent toxicity of amiodarone has not been completely elucidated even now, since pulmonary changes suggestive of an immune process can occur even at low doses. When there is reason to suspect the presence of amiodarone pneumopathy, the preparation should be discontinued. Radiological and clinical findings generally regress with cortisone treatment.

[Angiographic diagnosis and therapy of acute and chronic gastrointestinal hemorrhages].

In acute gastrointestinal bleeding visceral angiography has been showing its importance for years. It contributes to diagnosis especially in cases with persistent acute hemorrhage. In chronic gastrointestinal bleeding conventional radiographic procedures such as upper gastrointestinal series and barium enema will be preferred to angiography. The function of the radiologist goes beyond mere diagnosis of gastrointestinal bleeding. Treatment with vasopressin via the angiographic catheter has proven its clinical value. This method will be indicated especially in cases with high risk anesthesia and surgery. It will help to postpone necessary surgery to a more favorable moment following hemostasis. Side effects such as hypertension and antidiuresis are relatively rare and easy to manage. Numerous substances are used for embolization showing that ideal material has not been found yet and further development seems necessary. In contrast to vasopressin treatment, vascular occlusion is often irreversible, complications (unwanted reflux of embolization material, necrosis and plugging of the catheter) are more difficult to manage. Superselective visualization of a bleeding artery is always needed. Embolization is justified in cases when a possibility for anesthesia and surgery cannot be foreseen. The electrical vascular occlusion using direct current is still in the phase of animal experiments; its clinical value has not sufficiently been assessed as yet.

[Aseptic necrosis of the femoral head in lymphogranulomatosis and chronic myeloic leukemia treated intermittently with cytostatic agents and steroids (author's transl)].

Four male patients with the age from 31--43 years with lymphogranulomatosis and a 23 year old patient with chronic myeloic leukemia developed aseptic necrosis of the femoral head 15 to 69 months after treatment with a combination of cytostatic substances and steroids. In a patient who received maximal prednisone applications aseptic necrosis of the humeral head has been observed also. With increasing life expectancy asceptic bone necrosis due to treatment can appear as a late complication. The early recognition is important. The advancing of this irreversible bone destruction and the associated morbidity can be avoided by immediate cessation of the steroid application. Conservative treatment is indicated.

[Radiograph and observation of the development of Q-fever pneumonia (author's transl)].

The radiograph in Q-fever pneumonia and the course of Q-fever was reported with the help of 12 clinically examined cases. Q-fever pneumonia is not to be diffrentiated from viral pneumonia or mycoplasmal pneumonia. A chronic course with residual infiltrates which lasts as long as two or three months is, however, more frequent in Q-fever pneumonia. According to our observations, a correlation seems to exist between the severity of the clinical symptoms, the extent of the pulmonary infiltrate and the level of the titer of the complement fixation.

[Vena cava occlusion-syndrom by leiomyosarcoma. Two case reports (author's transl)].

Two cases of occlusion of the inferior vena cava by leiomyosarcoma are reported. This localisation is extremely rare for mesenchymal tumors. The neoplasm originated from the wall of the vena cava, expanded forward into the lumen of the vessel, in one case up to the right atrium. Collateral circulation, anasarca edema and varices develop by this occlusionsyndrome. The fatal outcome of the disease is usually determined by right heart failure and not by metastases directly. In most cases diagnosis is made by autopsy. In cavography the differential diagnosis of thrombosis might include the rare possibility of leiomyosarcoma of the caval vein. Only early diagnosis makes succesful surgical therapy possible.

[Clinical course of arteriosclerosis of coronary and lower limb arteries (author's transl)].

The clinical course of arteriosclerosis was evaluated in 9 patients with coronary sclerosis and in 25 with peripheral arterial occlusive disease by means of repeat angiographies following primary angiography after 22.5 and 36.6 months, respectively. During the period of observation arteriosclerosis had progressed in all cases except in two patients with peripheral arterial occlusive disease. Despite intensive therapeutic efforts including control of risk factors, dietary care, guided or unguided exercise and the attempt to change unsatisfactory living conditions, progression of arteriosclerosis could not be interrupted. If treatment delayed progression of arteriosclerosis cannot be decided. All vascular areas were affected indiscriminately by progression and no particular localisation was preferred. Intensive exercise does not seem to delay progression of arteriosclerosis.

[False diagnosis of a splenic cyst. A report about arteriography in cystic lesions of the spleen (author's transl)].

A false diagnosis of splenic echinococcal cyst is reported. Angiographic criteria of this misleading lesion are compared with those of three cases with splenic cysts (two were confirmed surgically). Depending on the size of the cyst, spreading and dislocation of branches of splenic arteries as well as definitsmothly outlined parenchymal defects become visible. Surrounding parenchyma may be partially compressed. Calcifications of the cystic wall do not allow differentiation between primary and parasitic cysts. The Casoni test alone is not sufficient as a primary diagnostic tool as it is false positive often. Additional complement binding test for echinococcus is recommended.
