{"title":"[Hip screening in newborn infants. Clinical and ultrasound results].","authors":"U Dorn","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A routine orthopaedic examination of each newborn was performed at the Salzburger Landesfrauenklinik (Department for gynaecology and obstetrics) since 1964. The results of these examinations were stored in an electronic database since 1978 and were now evaluated in a retrospective analysis. The examinations were performed by 8 orthopaedic surgeons between I/1978 and IX/1984. 5.9 percent of all newborns had a limited abduction and 13.2 percent a lax hip. Hips with limited abduction and lax hips were not classified as pathological but were recommended for strict observation and X-ray control at an age of four months. A similar rate of instable hips such as subluxatable (= 2.11%) and luxatable (= 0.63%) hips were also observed by other authors, whereas quite lower rates of instable hips in newborns were reported from several other European parts. Mau indicated the limited value of clinical examinations particularly when evaluating data in a multicenter study was concerned. In our study each examiner had a statistically significant variation of his results which we found by establishing an examiners ratio (Formula: see text). Since October 1984 the clinical routine newborn screening was completed by an obligatory hip sonography in the first days of life. The sonographic examination and classification was done according to Graf's method. Real-time ultrasound machines with linear 5 MHZ-transducer were used. 8.221 newborns were examined between X/1984 and XII/1988. 72.51 percent were type Ia, b. 25.63% were categorized as type IIa; 1.66 percent were classified type IIc, D; 0.16 percent were type IIIa hips. Only one hip was classified as type IV, this was a teratological dislocated hip. 1.31 percent of all hips showed a pathologic sonogram (= type IIc, D, IIIa) without having shown abnormalities, when clinically examined a few days before. In our opinion these results emphasize the value of a sonographic newborn screening. The majority of hips with distinct abnormalities only (= lax hips, limited abduction) was type Ia, b, or IIa, whereas the majority of clinical instable hips had pathologic sonograms (= IIc, D, IIIa). Newborns delivered by breech presentation had a significant higher percentage of clinically abnormal hips (= 7.48 subluxatable and luxatable hips). The percentage of pathologic sonograms (8.81%) and type IIa-hips (= 42.78%) was significantly higher compared to the normal delivered group. 336 premature newborns were found to have a statistically significant higher percentage of type Ia, b-hips (= 82.73%) and a statistically equal percentage of sonographically pathologic hips (= 0.89%) in comparison to the mature newborns.(ABSTRACT TRUNCATED AT 400 WORDS)</p>","PeriodicalId":76822,"journal":{"name":"Wiener klinische Wochenschrift.

Correction to protein or albumin did not significantly affect the results. Therefore, correction of fructosamine values from patients with normal protein and albumin values would not improve the clinical significance of fructosamine. Fructosamine concentrations of heparin plasma from non-diabetics also fell within the serum fructosamine normal range. The fructosamine concentration from non-diabetic dialysis patients was significantly higher and more widely distributed than that of the reference collective despite normal blood glucose concentration. Relating fructosamine to protein had no substantial effect, whereas the differences were even increased when fructosamine was related to albumin. On the present stage of knowledge it might be considered to establish a reference interval for dialysis patients. It appears that the fructosamine estimation may then be successfully applied also to dialysis patients. Although dialysis resulted in hemoconcentration, the fructosamine concentration remained virtually unchanged. Referencing both values before and after dialysis to protein or albumin improved the correlation, but substantial differences were introduced as well. However, none of several parameters measured in parallel interfered to a degree which might explain such differences.

From a group of 10 diabetics day profiles of glucose, protein, albumin, and fructosamine were recorded by measuring these parameters three times per day at 8.00, 11.30, and 15.00. The fructosamine concentration was essentially constant also when related to protein or albumin. Fructosamine, HbAlc, CK, and CK-MB were determined from 12 diabetics with fresh myocard infarct (7 diabetics, 5 non-diabetics). Surprisingly, diabetics as well as non-diabetics manifested high fructosamine concentrations. The origin of the fructosamine increase with non-diabetic myocard infarct patients is not yet known. Possibly the acute metabolic disorder plays an important role. An influence of fibrinogen on fructosamine is also conceivable. Additional investigations, including therapy of lysis, will be carried on. The stability of the fructosamine was examined by storing 50 sera (fructosamine 295-491 mumol/l, glucose 180-279 mg/dl) at different temperatures (+ 25 degrees C, + 4 degrees C, - 20 degrees C).
