[Carcinoid tumor of the lung in childhood--review and case report (author's transl)].

Carcinoid tumors of the lung are rare in childhood. Still they have to be taken in account as a possible reason for chronic pneumonitis, (with) cough or even hemoptysis. Misinterpretation of symptoms is the cause for the frequently long time lapse before the correct diagnosis is established. The crucial examinations are the history of symptoms, chest X-ray, tomography, and bronchoscopy, which lead to the correct diagnosis in about 75% of the cases. Treatment of choice is operative, with the aim to conserve as much functioning lung as possible. Radiotherapy has only palliative effects. The prognosis is rather good for the carcinoid tumor of the lung in general, 80% achieve a 5 years survival rate. The carcinoid tumor of the lung is now as for the newest definition defined as a separate group and should not be mixed up with "bronchial adenomas". Adenoid cystic carcinoma (cylindroma) and mucoepidermoid carcinoma of the bronchus are defined as carcinomas and believed to arise from respiratory glands.

[Structural changes in clinical pediatrics with special reference to small departments (author's transl)].

Changing facts and developments in clinical pediatrics in Germany during the past years have been analysed and discussed. Facts which altered the quantity and quality of clinical pediatrics are demonstrated by own observations, and informations collected from all pediatric departments in the FRG and West-Berlin. The need for sufficient numbers of staff to meet with the changing and intensified tasks of clinical pediatrics is emphasized.

Chondroectodermal dysplasia (Ellis--van Creveld syndrome) with dysplasia of renal medulla and bile ducts.

A case of a 28-month-old boy with chondroectodermal dysplasia (Ellis-van Creveld syndrome) is reported. Besides polydactyly, ectodermal dysplasia, acromelic dwarfism and congenital heart defect, which are characteristic morphologic features of the syndrome, additional dysplastic developmental defects were discovered in the kidneys, liver, and lungs. Detailed histopathologic studies of the growth plates of tibia, femur and ribs disclosed an irregular, partly hyperplastic, partly dystrophic appearance of the epiphyseal cartilage, which was not resorbed properly by the invading blood vessels. Focal areas of necrosis occurred and barriers of tongue-shaped cartilaginous peninsulas persisted. Regular enchondral ossification was hindered and compensatory membrane ossification was found in the fibrosing metaphyseal bone marrow adjacent to the cartilage. Dysplasia and fibrosis of the renal medulla plus interstitial fibrosing nephritis in the cortex resulted in kidney contraction and renal failure. Hepatomegaly, portal fibrosis and bile duct hyperplasia and dysplasia were detected at autopsy, but did not have any clinical significance. These findings once again emphasize that derivatives of all three germ layers are involved in the Ellis-van Creveld syndrome. The possibility that a single metabolic or structural abnormality of the mesenchymal tissues could be responsible for the various organ dysplasias is discussed.

[Efficiency of diagnostic procedures in clinical pediatrics (author's transl)].

Diagnostic procedures were evaluated in a prospective study including 1099 unselected children seen at a children's hospital. The predominant importance of a detailed case history (88,3%) and of the clinical examination could be demonstrated. On the other hand, apparative routine examinations were of very limited value, mostly to exclude particular diagnoses. The efficiency of apparative diagnostic procedures could be improved by allowing for a more differentiated indication of their use.

[Fatal poison disease of a child following massive wasp stings (author's transl)[].

A child aged 4 years was stung by more than 250 wasps. There was no anaphylactic shock. There rather were increasingly heavy ictero-hemorrhagic symptoms with simultaneous insufficient kidney function. On the second day of the disease disorders of the CNS started, as well as circulation insufficiency and disorder of the heart function. According to the signs there was no intravasal coagulation or hemolysis. Heavy doses of corticoids were successless, just as a peritoneal dialysis starting on the 3rd day of the disease. The child died 5 and 1/2 day after the wasps' attack. The pathophysiology and the possible therapeutic consequences of the case as well as rapid protective actions in such a case of insect attack are being discussed.
