[Carcinoma metastasis in cutaneous osseous metaplasia. Differential diagnosis of osseous tumor metaplasia].

The formation of metastases in heterotopic ossifications is a very rare finding. The example of a 63-year old male who underwent Billroth II procedure because of recurrent duodenal ulcers 30 years ago and median laparotomy of the upper abdomen because of blunt abdominal trauma 9 years ago shows the formation of metastasis of a carcinoma found in the gastroenteral anastomosis in a focus of heterotopic ossification, which was located in the scar of the upper abdominal laparotomy.

[De Sanctis-Caccione syndrome: xeroderma pigmentosum with oligophrenia, short stature and neurologic disorders].

A 6 year-old boy with de Sanctis-Cacchione syndrome is reported. This syndrome is characterized by the triad xeroderma pigmentosum (XP), mental deficiency and neurological disturbances. The patient's cells were assigned to genetic complementation group A by use of the cell fusion technique.

Electrosurgery in arthroscopy.

Electrosurgery using high-frequency (HF) technique in arthroscopic operations has been used routinely in our hospital for 8 years. Main indications are meniscal resections, lateral release, plica cutting, and arthrolysis. The main instrument is a hook, which is insulated up to the tip and also cuts meniscal tissue.

[Fasting volume and contractility of the gallbladder after total and subtotal gastrectomy with Y-Roux anastomosis. A prospective study].

Gallbladder volume and contraction after a fatty meal was determined in 14 patients with gastric cancer before and 3-4 months after gastrectomy (7 total and 7 subtotal gastrectomies) with Roux-en-Y anastomosis. All patients had an increased gallbladder resting volume (p less than 0.001) and 10 of 14 patients (6 after total gastrectomy and 4 after subtotal gastrectomy) had an increased minimal residual volume after fatty meal stimulation (p less than 0.

[Thalamic infarcts--clinical aspects, neuropsychological findings, prognosis].

Results of clinical investigations and CCT of 23 patients with thalamic infarctions were evaluated retrospectively. Nineteen patients underwent a clinical and 15 a neuropsychological examination one to 5 years after their stroke. Regarding the affected vascular territory, the patients were divided into the following subgroups: paramedian infarctions (posterior thalamo-subthalamic arteries, 13 patients, among them 5 bilateral infarcts); anterolateral infarcts (tuberothalamic arteries, 5 patients); posterolateral infarcts (thalamo-geniculate arteries, 5 patients).

[Diagnostic value of ultrasonographic testing of the gallbladder function in cholelithiasis].

Decrease in gall-bladder volume after intake of a test meal was assessed by ultrasound in 30 patients (24 females, 6 males; mean age 55 [22-82] years) with indications for elective or early elective cholecystectomy for cholelithiasis. Patients were assigned to three groups, based on intraoperative and histological gall-bladder changes: group 1 (n = 17), without changes or with mild chronic cholecystitis; group 2 (n = 4), with severe chronic inflammatory changes; group 3 (n = 9), with acute cholecystitis or cystic duct occlusion. A volume decrease of at least 30% after the test meal excluded only acute wall inflammation (negative predictive value 95.

Ring chromosome 22: a case report.

A three year old girl with ring chromosome 22 is described. The clinical findings include epicanthus, flat nasal bridge, hypertelorism, long eye-lashes, lymphoedema, hypoplastic toe nails, hydrocephalus and muscular hypotonia. Speech and language development is delayed.

[Tumor form of lymphostatic papillomatosis of the skin].

The case of a patient with two plantar papillomatous tumours that had had a relapsing course over 10 years is presented. The tumours were located on the right forefoot and the left great toe. Several operations were performed for different diagnoses, i.

[Experimental studies of change in the center of rotation of the moveable segment after intervertebral disk removal].

The in vitro effect of nucleus pulposus removal from human lumbar FSU's was investigated in a special test apparatus. Instability was determined by ROM, loss of disc height and displacement of the center of rotation. Disc height showed a decrease of 3.

[Visual evoked discrimination potentials in childhood].

70 children without visual, developmental or neurological handicap in the age of 3 to 92 months were investigated. Using red and white light flashes non-target event-related evoked potentials have been registrated, white light serving as rare (20%) stimulus (Fig. 1 and 5).

[Motor neurography: simultaneous recording using surface and needle electrodes. A comparative study of the proximal and distal latency together with the motor nerve conduction velocity].

The generally accepted interpretation that the application of surface and concentric needle electrodes for the recording of evoked muscle action potential in motor nerve neurography showed the same results has been reconsidered, especially because until now, over 20 years after the introduction of this neurophysiological method in routine clinical work, no exact statistically verified examinations have been done on this subject. Proximal and distal latency as well as motor nerve conduction velocity were determined in the following nerves in 100 subjects (71 healthy subjects and 29 patients): tibial, peroneal, ulnar, median. All neurographic parameters were obtained by means of simultaneous recording with surface and concentric needle electrodes and compared with one another.

[1989 Bochum health education program for malignant melanoma].

The incidence rate of all skin cancer forms has been increasing during the last few decades. The incidence of malignant melanoma is important due to its very high malignancy and its growing spread especially among young patients. Malignant melanoma is mainly observed on the external skin and is therefore well suited for screening methods.

[Apparent central facial paralysis in Lyme borreliosis].

In childhood Lyme-Borreliosis often presents as facial palsy. This progredient infectious disease is to be treated by intravenous penicillin therapy in order to avoid future complications. In three out of four own observations facial palsy raised suspicion towards central origin.

[Campylobacter pylori-associated chronic gastritis: a new entity in gastroduodenal diseases?].

Clinical, morphological and immunological data in addition to animal studies clearly support the conclusion, that Campylobacter pylori infection is a direct cause (sufficient condition) for chronic type B gastritic in man. C. pylori gastritis is primarily a histologic entity defined by the presence of a gastric mucosal cellular infiltrate and the histologic demonstration of typical curved bacilli.

[Therapy of Campylobacter pylori infection].

A simple and efficient therapy eradicating C. pylori with high reliability from gastroduodenal mucosae is presently unknown. In regard to such a "puristic" approach, antibiotics given as monotherapy are presently as ineffective as bismuth salts, which may temporarily reduce the bacterial density, but yield a low complete bacterial eradication rate of not more than 10% to 30% of all patients.

[Recurrent staphylodermas in marked IgE elevation: the hyper-IgE syndrome].

This is a report of a 6-year-old boy with repeated staphylococcus infections especially in the hairy region of the head. Investigating the disease an extremely elevated IgE of 10,000 KU/l was found, specific IgE in RAST only at a low level. The immunologic investigations showed a reduction of the T-suppressor-cells and an increase of IgG levels.

[Effect of nitrogen oxides and suspended dust in the air on the incidence of inpatient treatment of children with stenosing laryngotracheitis (pseudocroup). Results of an 8-year epidemiologic retrospective study based on inpatient case figures and area-related data of air measurements in the Bochum city district].

Results of a recently published study over a test period of 18 years showed no relationship between croup incidence of hospitalized children and SO2 levels measured in the city of Bochum. In the following study 642 hospitalized children with stenosing laryngotracheitis were examined for a possible time-dependent relationship between croup incidence and NO2, NO- and dust immission levels measured in the city of Bochum (approx. 1000 000 readings).

[Talocrural angle and ankle joint mobility in Germans and Japanese].

1980 Krämer and Gudat introduced the talo crural angle, which provides exact measurement of the mobility of the ankle joint. In field studies in Germany we found a greater range of mobility in female compared with male persons. With advancing age range of mobility decreased in both sex.
