Domestic hen (Gallus gallus) eggs were incubated at 37.5 degrees C and 80% humidity for 24 h. At that moment, 5 ml of albumen were aspirated by sterile puncture of the shell, and the incubation was resumed. The embryos were recovered and studied at the 8th, 10th and 14th days. Almost half (45%) of the 602 treated embryos survived and 73 of them (12%) had various malformations. Thirty-six (6%) suffered NTD of which 30 were open myelomeningocele, 2 meningocele and 4 encephalocele. The anatomy of the defects was astonishingly similar to that of the human malformation. Whether these experimental NTD are induced by mechanical or nutritional modifications of the internal environment of the egg is unknown, but the similarity of the lesion with those in humans make them suitable for further investigation of these issues. We believe that this relatively simple and inexpensive model is a suitable tool for research on spina bifida.","PeriodicalId":77648,"journal":{"name":"Zeitschrift fur Kinderchirurgie : organ der Deutschen, der Schweizerischen und der Osterreichischen Gesellschaft fur Kinderchirurgie = Surgery in infancy and childhood","volume":"45 Suppl 1 ","pages":"20-2"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2008-1042628","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13443265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiences of diagnosis and uncommon complications of bleeding in a case of a now 21-year-old male are reported. Real-time ultrasound examination and cavography are very useful for diagnosis and planing of surgical intervention. Causes of complete occlusion of the VCI in early childhood are malignant tumours or an abdominal mass. Usually cava-azygos collaterals may enlarge sufficiently. Normally, vertebral pathways with sufficient circulation prevent oedema of the limbs, bilateral varicoceles and caput medusae of the abdominal wall. The vasa vasorum or intrahepatic pathways rarely contribute to the collateral circulation. In the present case, varicosities of the duodenum caused intestinal bleeding. Neither treatment by resection nor a shunt procedure may promise definite relief if collateral veins are bleeding diffusely. Stenosis and occlusion of VCI and small shot-like ulcers above the varicosities of the duodenum were the major observations found in the case under discussion.","PeriodicalId":77648,"journal":{"name":"Zeitschrift fur Kinderchirurgie : organ der Deutschen, der Schweizerischen und der Osterreichischen Gesellschaft fur Kinderchirurgie = Surgery in infancy and childhood","volume":"45 6","pages":"379-82"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2008-1042619","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13444124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterised by the maintenance of a high pulmonary vascular resistance and right-to-left shunting through the ductus arteriosus and foramen ovale. Infants with a wide variety of underlying clinical conditions develop PPHN. According to Rudolph three main anatomic types of PPHN can be identified: normal pulmonary vascular development increased pulmonary vascular smooth muscle development decreased cross-sectional area of pulmonary vascular bed. It is important to realize that several pathophysiologic mechanisms may coexist and interact. Besides metabolic and respiratory acidosis, hypercapnia and hypoxaemia some other factors induce pulmonary vasoconstriction. Thromboxane, leukotrienes and prostaglandins play a decisive role. Since PPHN can be associated with a broad spectrum of clinical conditions, a specific clinical picture is lacking. The baby is usually term or post-term, cyanotic immediately after birth or some hours later. Birth asphyxia, hyperviscosity, sepsis and aspiration of meconium have been recognized as predisposing factors. The diagnosis can be confirmed by echocardiography. Contrast echo will indicate right-to-left shunting with normal anatomy. Currently hyperventilation, tolazolin, chlorpromazin and dopamine/dobutamine have been advocated as central foci for clinical therapy. Recently prostacyclin was introduced as a specific pulmonary vasodilatator.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":77648,"journal":{"name":"Zeitschrift fur Kinderchirurgie : organ der Deutschen, der Schweizerischen und der Osterreichischen Gesellschaft fur Kinderchirurgie = Surgery in infancy and childhood","volume":"45 6","pages":"336-41"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2008-1042612","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13442113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principle of the technique has been reported in previous papers (1, 2, 3) and has been shown to provide a reliable measure of intracranial pressure (ICP) in terms of induced displacement of the tympanic membrane. This study concentrates on the assessment of shunt blockage in spina bifida patients who subsequently underwent shunt revision. The tympanic displacement technique is shown to be of value to this patient group in three respects. Firstly as a research technique to study group-averaged ICP measurements where the ICP needs to be known but invasive measurements cannot be justified. Secondly for assessing shunt dysfunction in individual patients and, finally, in determining the success of shunt revision surgery. The technique was found to be extremely sensitive to relative changes in ICP with shunt revision or any subsequent blockage. The technique is more reliable diagnostically in instances where the patients act as their own controls and a comparison with baseline measurements can be made. Three case reports are illustrated which were selected from those patients tested to emphasise the importance of serial measurements of ICP over period of several days post-revision. The tympanic displacement technique is shown to provide a practical and acceptable method by which this can be undertaken.","PeriodicalId":77648,"journal":{"name":"Zeitschrift fur Kinderchirurgie : organ der Deutschen, der Schweizerischen und der Osterreichischen Gesellschaft fur Kinderchirurgie = Surgery in infancy and childhood","volume":"45 Suppl 1 ","pages":"26-8"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2008-1042630","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13443267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Follow-up examinations were performed in 38 patients. 24 patients were entirely without complaints, 9 had mild subjective complaints, and only 5 patients stated they were suffering continually from dyspnoea. Lung function tests were conducted in all patients, revealing a significant drop in vital capacity as the number of resected segments increased. The intrathoracic gas volume expressed in percentage of the standard value increased significantly with the number of resected segments. The flow volume curves dropped with the number of resected segments, whereas the airway resistance increased. These studies show that lung resections are not always tolerated without restricted function even by children. Hence, lung resection should be performed with utmost discretion and only if absolutely necessary. This is all the more important since adjacent pulmonary tissue may also be involved in the pathological process due to the underlying disease.","PeriodicalId":77648,"journal":{"name":"Zeitschrift fur Kinderchirurgie : organ der Deutschen, der Schweizerischen und der Osterreichischen Gesellschaft fur Kinderchirurgie = Surgery in infancy and childhood","volume":"45 6","pages":"349-59"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2008-1042614","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13442115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
