Abnormalities in gallbladder dynamics of type 1 (insulin-dependent) diabetic patients with autonomic neuropathy.

The aim of this study was to evaluate gallbladder dynamics in insulin-dependent diabetic patients with and without autonomic neuropathy. Gallbladder dynamics was studied by a scintigraphic method after a test meal in 26 insulin-dependent diabetic patients and 10 normal individuals. The presence and severity of autonomic neuropathy were defined according to the number of abnormal cardiovascular reflex tests: absent (no abnormal test), mild (1-3 abnormal tests), and severe (4-5 abnormal tests). The time from the moment when the patient started to take the test meal to the beginning of gallbladder emptying was longer (P = 0.01) in diabetic patients with mild (N = 11, 12.1 +/- 7.6 min) and severe neuropathy (N = 8, 11.0 +/- 10.6 min) than diabetic patients without autonomic neuropathy (N = 7, 3.9 +/- 4.4 min) and controls (N = 10, 4.8 +/- 4.2 min). The ejection rate was higher (P = 0.02) in the group with severe autonomic neuropathy (N = 8, 5.1 +/- 3.3%/min) than diabetic patients with mild (N = 11, 2.0 +/- 1.0%/min) or without autonomic neuropathy (N = 7, 1.8 +/- 0.8%/min) and controls (N = 10, 2.6 +/- 1%/min). Thirty-two percent of the diabetic patients with autonomic neuropathy presented increased perspiration, nausea and urgency to defecate after the ingestion of the test meal. A significant positive correlation of ejection rate with the presence of these symptoms (biserial point correlation test = 0.67, P < 0.01) was also observed. These data suggest that insulin-dependent diabetic patients with autonomic neuropathy present abnormalities of gallbladder emptying that could be related to specific gastrointestinal symptoms.

[Cardiovascular disorders with respiratory distress in childhood].

Because of their low prevalence cardiovascular abnormalities are an easily overlooked cause of persistent respiratory distress in childhood. A review is presented of the most common cardiovascular disorders that give rise to respiratory distress by compression of the airway at various levels. At tracheal level the double aortic arch and the aberrant right subclavian artery are the most frequent anomalies. Bronchial compression is mostly due to left to right shunting through either a persistent ductus arteriosus or a ventricular septal defect. Compression of the lung parenchyma itself is in most cases caused by dilatation of the left ventricle. Anatomy, symptomatology, diagnosis and therapy of the cardiovascular disorders are described.

Holt-Oram syndrome associated with hypoplastic peripheral vasculature and midsystolic click.

Holt-Oram syndrome is a rare, autosomal dominant syndrome characterized by upper extremity skeletal abnormalities and cardiac defects. The most common skeletal anomalies involve the thumbs and range from minor radiographic abnormalities to phocomelia. The most common cardiovascular abnormality is ostium secundum ASD, followed by ventriculo-septal defect and ostium primum ASD. MVP and hypoplastic peripheral vasculature of the upper extremities have been reported only rarely. We have reported the case of a patient with HOS who has both hypoplastic peripheral upper extremity vasculature and evidence of MVP.

[Heart malformations and vascular complications associated with Turner's syndrome. Prospective study of 26 patients].

Turner's syndrome is associated with congenital heart disease in a third of cases. Several reports of aortic dilatation and of death by dissection or rupture of the aorta have been published. The authors undertook a prospective study to assess the incidence of cardiac malformations and aortic dilatation in genetically confirmed Turner's syndrome. Twenty-six out of 34 patients recalled (76%), aged 7 to 30 years (average 17 +/- 6 years) accepted their inclusion in this study and underwent clinical examination, ECG, chest X-ray and echocardiography. Thirteen patients had a monosomy 45X and 13 a mosaic or structural abnormality. Six had a history of cardiovascular disease (operated coarctation: 2 cases, kinking: 2 cases, Hypertension: 2 cases). Eight patients (30%) had one or several anatomical cardiovascular abnormalities: bicuspid aortic valve (19.2%), abnormalities of the aortic isthmus (kinking or coarctation) (15.4%), aortic regurgitation (7.7%), mitral stenosis (3.8%), partial anomalous venous drainage (3.8%), patent ductus arteriosus (3.8%) and left superior vena cava (11.5%). Systematic evaluation of the aorta resulted in the diagnosis of dilatation of the ascending aorta in 1 case and dilatation of the sinus of Valsalva in 2 other cases. The authors conclude that echocardiographic evaluation is essential after the diagnosis of Turner's syndrome. It should be repeated regularly to detect dilatation of the aorta which carries the risk of serious complications, such as rupture or dissection of the aorta.

[Special anesthesiological aspects in patients with Niikawa-Kuroki ("Kabuki Make-Up") syndrome].

The Niikawa-Kuroki ("Kabuki Make-up") syndrome (NKS) is a rare disease with a characteristic array of multiple congenital anomalies. The syndrome is characterised by distinct craniofacial dysmorphias, moderate mental retardation, skeletal abnormalities, cardiovascular and urogenital disorders, growth retardation and skeletal muscle abnormalities. The inheritance of NKS is not completely clear. However, the available data are compatible with an autosomal dominant mutation with variable expressivity. There is no specific treatment for NKS. The patients require intensive support for the development of their mental and physical capabilities. Furthermore, therapy includes operative correction of the multiple anomalies. The risk of anaesthesia is increased in these patients because of a possible difficult airway, cardiovascular and urogenital diseases, and abnormalities of the skeletal muscles. Special problems associated with the anaesthetic management in patients with NKS are discussed in this case report.

Routine obstetrical ultrasound at 18-22 weeks: our experience on 7,236 fetuses.

OBJECTIVE: This study aimed at examining the detection rate of congenital abnormalities by using routine ultrasonography at 18-22 weeks of gestation. METHODS: The sample included 7,236 fetuses. A detailed sonographic examination was performed in each fetus and a neonatal evaluation or pathology examination was made to confirm the prenatal findings. RESULTS: The total prevalence of fetal abnormalities in our sample was 2.24% (162/7,236). There were 29/162 (17.9%) fetuses with CNS abnormalities, 27/162 (16.7%) fetuses with gastrointestinal abnormalities, and 28/162 (17.3%) fetuses with urinary tract abnormalities. There were also 31/162 (19.1%) fetuses with cardiovascular abnormalities, 26/162 (16.0%) with malformation of the limbs and musculoskeletal system, and 21/162 (13%) fetuses with other various abnormalities. The overall sensitivity in detecting fetuses with congenital abnormalities was 80.25% (130/162). The sensitivity per system was 93.1% (27/29) for CNS, 45.2% (14/31) for cardiovascular system, 85.2% (23/27) for gastrointestinal system, 85.7% (24/28) for urinary system, 84.6% (22/26) for musculoskeletal system, and 95.2% (20/21) for the rest of the abnormalities detected. We performed 40 pregnancy terminations in the group of malformed fetuses. Among the fetuses considered as normal, 1.7% had chromosomal abnormalities. CONCLUSIONS: The results indicate that routine sonographic examination at 18-22 weeks of gestation can detect the majority of congenital abnormalities. More experience is needed for the examination of the cardiovascular system, where the sensitivity was particularly low (14/31 or 45.2%).

Effects of posttraumatic stress disorder on cardiovascular stress responses in Gulf War veterans with fatiguing illness.

Abnormal cardiovascular stress responses have been reported in Gulf War veterans with chronic fatigue. However, many of these veterans also suffer from posttraumatic stress disorder (PTSD), which could potentially explain the reported abnormalities. To test this hypothesis, 55 Gulf veterans (GVs) with chronic fatigue syndrome (CFS) or idiopathic chronic fatigue (ICF) were stratified into groups with (N=16) and without (N=39) comorbid PTSD, and were compared to healthy Gulf veterans (N=47) on cardiovascular responses to a series of stressors. The CFS/ICF with PTSD group had lower blood pressure responses to speech and arithmetic tasks, and more precipitous declines and slower recoveries in blood pressure after standing up than the controls. Similar trends in the CF/ICF group without PTSD were not significant, however. Both CFS/ICF groups had blunted increases in peripheral vascular resistance during mental tasks. However, only the veterans with comorbid PTSD had diminished cardiac output responses to the mental stressors and excessive vasodilatory responses to standing. Symptoms of posttraumatic stress were significant predictors of hypotensive postural responses, but only in veterans reporting a significant exposure to wartime stress. We conclude that comorbid PTSD contributes to dysregulation of cardiovascular responses to mental and postural stressors in Gulf veterans with medically unexplained fatiguing illness, and may provide a physiological basis for increased somatic complaints in Gulf veterans with symptoms of posttraumatic stress.
