[Total laparoscopic hysterectomy. Operative technique, results and indications].

Total hysterectomy was performed via laparoscopy alone in 50 patients. In all cases, the operation was carried out using conventional, re-usable instruments (grasping forceps, laparoscopic scissors, bipolar coagulation). The mean duration of the operation was 163 min (range: 110-270 min). The mean drop in haemoglobin was 1.97 g/100 ml (range: 0-4 g/100 ml) and the average length of hospital stay was 3.9 days (range: 2-13 days). In one case (2%), we converted to laparotomy because a lateral myoma made it impossible to achieve haemostasis of the uterine pedicule under suitably safe conditions. No serious peri or post-operative complications were encountered. No second surgery was necessary and no transfusion was required. These results confirm that total laparoscopic hysterectomy via laparoscopy is a safe, feasable and reproductible technique. Future work will establish the exact place and methods for laparoscopic surgery for hysterectomy. Laparoscopic surgery is only indicated when vaginal hysterectomy is contraindicated or impossible. Laparoscopic hysterectomy constitutes an alternative to laparotomy rather than the vaginal hysterectomy. The combination of an immobile uterus and poor vaginal accessibility is the prime indication for total hysterectomy via laparotomy.

[Aneurysms of the intra-atrial septum complicated by cerebral ischemia in young subjects. 4 cases].

Transoesophageal echocardiography has improved the detection of potential sources of cerebral embolism. We report our experience with a group of 38 patients under 45 years of age who were examined after an arterial ischaemic cerebral event. We observed 4 patients (2 males, 2 females; age 17, 24, 38 and 40 years) with an atrial septal aneurysm. Cerebral ischaemia was permanent in 3 patients and temporary in 1 and a cerebral embolism was the most probable cause based on angiographic findings. The atrial septal aneurysm was only diagnosed by transoesophageal echocardiography (type IA in case 3, IB in the others). A patent foramen ovale was observed in 3 and this abnormality, which is known to have a high prevalence in the general population, could at most be an aggravating factor. In our series, we can assume a causal association between atrial septal aneurysm and stroke in young patients (10.5% among 38 young stroke patients vs 3% of 30 patients referred for other reasons). The treatment is still under discussion although the consensus would favour surgery if another heart malformation is associated, if a visible thrombus is identified or if repeated cerebrovascular events occur despite adequate anticoagulation. Studies conducted in large series of patients should provide more adequate therapeutic schemas.

Total laparoscopic hysterectomy: preliminary results.

Total hysterectomy carried out entirely via laparoscopy benefited 31 patients. In all cases the operation was carried out using conventional, re-usable instruments (grasping forceps, laparoscopic scissors, bipolar coagulation). The mean duration of the operation was 171 min. No serious peri- or post-operative complications were encountered and no transfusion was required. The mean drop in haemoglobin was 1.3 g/100 ml and the average length of hospital stay was 4 days. In one case (3.26%) we converted to laparotomy because a lateral myoma made it impossible to achieve haemostasis of the uterine pedicle under suitably safe conditions. These results confirm that total hysterectomy via laparoscopy is a safe, feasible and reproducible technique. Future work will establish the exact place and methods for laparoscopic surgery for hysterectomy; it can be suggested, however, that laparoscopic surgery is only indicated when vaginal hysterectomy is contra-indicated or impossible. So, laparoscopic hysterectomy constitutes an alternative to laparotomy rather than to vaginal hysterectomy. The combination of an immobile uterus and poor vaginal accessibility is the prime indication for total hysterectomy via laparoscopy.

Rheumatic heart disease and Sneddon's syndrome.

BACKGROUND: As the pathogenesis of Sneddon's syndrome is unknown, research for associated disease can facilitate our understanding. CASE DESCRIPTION: Of nine patients with Sneddon's syndrome, three had rheumatic heart disease (mitral valve stenosis, regurgitation, or both) due to rheumatic fever or Sydenham's chorea. Transient anticardiolipin antibodies or positive skin lupus band test were present. CONCLUSIONS: Sneddon's syndrome can have multiple causes. In some patients, rheumatic heart disease is a possible causal association.

[Myxoma of the left atrium with neurologic manifestations: 8 cases].

A cohort of 8 patients with myxoma of the left atria and neurological manifestations is reported. Cerebral ischaemia, sometimes responsible for epileptic seizures, led to the discover of the myxoma (5 cases) or recurrence after exeresis (1 case) with imaging evidence of cerebral infarction in 5 cases. The first manifestation was a retinal embolism and temporary ischaemia in 1 case and pulmonary embolism with regressive cerebral ischaemia in another case with bilateral myxoma. Some clinical particularities should be underlined including exercise-induced neurological defect (3 cases), systemic embolism associated with cerebral infarction (3 cases), migraine headache as the initial manifestation (1 case) preceding by a pseudolupic syndrome suggesting the possibility of cerebral vasculitis or infectious endocarditis (1 case). The prognosis depends on the risk of recurrent atrial tumour formation (1 case). Metastases are rare. Multiple cerebral aneurysms (3 cases) did not lead to haemorrhagic complications.

[Neurologic emergencies in acute alcoholic intoxication].

Neurologic complications of acute alcohol intake are less well known to the general practitioner than those punctuating the course of chronic alcohol dependency. The state of ebriety is a poor incentive to precise neurologic analysis and follow-up. Nevertheless, only such surveillance in acute intoxication can distinguish a specific neurological complication, a complication following a fall or prolonged immobilisation, or rapid decompensation of alcoholic encephalopathy. Among the specific complications, myopathies and strokes are described here because of their rarity compared to the more common epilepsy and withdrawal syndromes. The neurologic semiology of ebriety is reviewed, including recent pathophysiological acquisitions specifying the mechanism of functional disorders in regions susceptible to alcohol such as the cerebellum and the reticular formation.

Influence of calcitonin treatment on the osteocalcin concentration in the algodystrophy of bone.

Algodystrophy (AD) attacks all tissues in the affected region and results in the rapid demineralization of bones. Osteocalcin (OC) and alkaline phosphatase (AP) are markers of bone turnover. Calcitonin is the treatment of choice of AD. Two groups of patients were studied: Group I (n = 8)--acute stage of AD (before and during the calcitonin treatment), Group II (n = 5)--late chronic stage of AD. In the acute stage of AD both OC level and AP activity were increased. They were normal in the chronic stage of AD. During the calcitonin treatment OC level normalized after 14 days and then increased again. During the treatment, AP activity temporarily increased and then returned to the initial level. We confirm that an increased bone turnover is observed in the acute stage of AD. Discrepancy between OC level and AP activity reflects the local metabolic disturbances. Salmon calcitonin inhibits the algodystrophic process and probably contributes to the activation of the skeletal restoration.

Growth hormone (GH) and GH-releasing hormone response to ACTH 1-17 at different times of day. Evidence of a circadian stage dependence.

The effect of injection of ACTH 1-17 on the secretion of GH has been examined at three different circadian stages (07, 14 and 21 h) in the winter. Each week for six consecutive weeks the subjects were investigated before and after I.M. injection either of saline (controls) or 100 micrograms ACTH 1-17. Each subject was his own control. The peak plasma concentration of GH was always found 40 min after the injection. The larger absolute increase and the greater AUC curve were seen following the injections at 14.00 h and 21.00 h. The findings could not be attributed to an effect on GH-RH, since secretion of it remained unchanged during the test.

Effects of oral contraceptives on carbohydrate and lipid metabolisms in a healthy population: the Telecom study.

In a cross-sectional study that aimed to identify risk factors for diabetes, 1290 consecutive, healthy, nonpregnant women of child-bearing age were examined in a center for preventive medicine. An in-depth interview about menses, use of oral contraceptives, and menopause was performed. Plasma glucose at fasting and 2 hours after a 75 gm glucose load, glycated hemoglobin A1c, fasting plasma insulin, total plasma cholesterol, and triglycerides were measured. Compared with nonusers taking no progestogens, oral contraceptive users (n = 431; 33.4%) were younger (p less than 0.001) and leaner (p less than 0.001). After adjustment for age and body mass index, oral contraceptive users had higher 2-hour plasma glucose (p less than 0.001), higher fasting plasma insulin (p less than 0.01), and higher triglycerides levels (p less than 0.01). Fasting plasma glucose, glycated hemoglobin A1c, and total cholesterol did not significantly differ between the two groups. In relation to dosage and types of steroid components, few differences have been found between high-dose and low-dose oral contraceptives or according to the estrogen-progestogen balance of the preparations. Use of oral contraceptives appears to induce an increase of insulin-resistance markers, which have recently been cited as risk factors for ischemic vascular diseases. These markers should be carefully monitored in oral contraceptive users.

Oral contraceptives, insulin resistance and ischemic vascular disease.

From a large prospective study on diabetes risks, 1112 professionally active, non-menopausal, non-pregnant, healthy women were cross-sectionally analysed according to their use of oral contraception. After adjustment for age, weight and diabetes risk factors, those taking the pill, compared to those who did not, had significantly higher fasting serum insulin, triglycerides and 2-h 75 g OGTT blood glucose levels. The insulin-resistance markers which have recently been cited as ischemic vascular disease risk factors should be carefully monitored in pill users.

Growth hormone secretion during sleep. II. Interrelationships between growth hormone secretion, insulin-like growth factor I and sex steroids.

The serum levels of insulin-like growth factor I (IGF I), dehydroepiandrosterone sulfate (DHAS), testosterone (T) and estradiol (E2) have been measured in 78 prepubertal and 57 early pubertal patients referred for short stature, at the same time when their secretion of GH was evaluated both during nocturnal sleep and by two conventional stimulation tests. According to the results of GH measurements they were considered as having a normal secretion of GH (group I), a complete GH deficiency (group II), a partial GH deficiency (group III), low responses to stimuli with normal secretion during sleep (group IV) or a nocturnal neurosecretory dysfunction (group V). Though widely scattered, the IGF I levels showed the following characteristics: a significant increase at puberty from 0.77 to 1.29 U/ml (p less than 0.001) in the so-called endocrinologically normal patients of group I, not in the other groups; in the prepubertal patients of group I, a correlation of IGF I with chronological age (r = 0.47, p less than 0.005) and bone age (r = 0.52, p less than 0.002); significantly reduced IGF I levels in patients of group II having complete GH deficiency (p less than 0.001); no significant differences between prepubertal patients with partial or atypical GH deficiency from groups III, IV, V and prepubertal patients from group I; lower pubertal levels in groups III, IV, V than in pubertal patients from group I (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

[Growth hormone deficiency (hGH) in 1 case of terminal renal insufficiency treated with chronic hemodialysis].

The authors report the clinical history of a seventeen years old boy with renal failure treated with chronic haemodialysis since eleven and a half years of age. Growth velocity was 1.5 cm/year. The stature was below 5 SD as compared to the mean for the age. Hormonal measurements showed a complete growth hormone (hGH) deficiency and hyperparathyroidism. Thyroid, adrenal and gonadic secretions were normal, but the responses of TSH and prolactin to TRH were abnormal, showing an hypothalamic disturbance. hGH treatment, with thyroxin substitution, enhanced growth velocity up to 4 cm/year. Respective influences of hGH treatment, puberty and hyperparathyroidism on the incomplete correction of growth velocity are discussed.

[Relation of the secretion of growth hormone (GH), somatomedin C/IGF I (IGF I) and steroids before and after the beginning of puberty in patients of short stature].

Somatomedin C/IGF I, dehydroepiandrosterone sulfate (DHAS), testosterone (T) or estradiol (E2) have been measured in 154 patients of a previous study in which growth hormone (GH) responses to classical pharmacologic stimuli and spontaneous growth hormone secretion during sleep were compared in short children before and at the beginning of puberty. Five groups were identified: Group I, normal growth hormone secreting children; group II, completely growth hormone deficient; group III, partially growth hormone deficient; group IV, with normal sleep secretion and low responses to stimuli; group V, with the reverse situation. The somatomedin C/IGF I levels were widely dispersed. In group I, the mean +/- SEM levels of somatomedin C/IGF I were 0.77 +/- 0.047 U/ml before puberty and 1.36 +/- 0.142 U/ml in early pubertal patients, with a relation to age (r = 0.52, p less than 0.001). The difference between prepubertal and pubertal patients was significant. In groups II to V, there was no pubertal rise of somatomedin C/IGF I. In group II, the mean IGF I level was 0.48 +/- 0.05 U/ml, significantly lower than in prepubertal patients of group I. In groups III, IV and V, it was 0.7 +/- 0.069 U/ml, 0.8 +/- 0.059 U/ml, and 0.73 +/- 0.059 U/ml respectively, not different from prepubertal patients of group I, but significantly lower than in early pubertal patients of the same group. In prepubertal patients, somatomedin C/IGFI was slightly but highly significantly correlated to the growth hormone sleep secretion (r = 0.27, p less than 0.001) and to dehydroepiandrosterone sulfate (r = 0.36, p less than 0.001), but growth hormone and dehydroepiandrosterone sulfate were not correlated together.(ABSTRACT TRUNCATED AT 250 WORDS)

[The relation between the secretion of growth hormone (GH), somatomedin C/IGF I (IGF I) and steroids before and after the onset of puberty in patients of small stature].

Somatomedin C/IGF I, dehydroepiandrosterone sulfate (DHAS), testosterone (T) or estradiol (E2) have been measured in 154 patients of a previous study in which growth hormone (GH) responses to classical pharmacologic stimuli and spontaneous growth hormone secretion during sleep were compared in short children before and at the beginning of puberty.

Epidemiological features of glycated haemoglobin A1c-distribution in a healthy population. The Telecom Study.

HbA1c was measured in 3240 healthy non-diabetic adult individuals in a working population. There was no difference in HbA1c between sexes. The distribution of HbA1c was approximately normal with a slight difference between mean and median values at all ages in both sexes. HbA1c increased with deterioration of glucose tolerance and with all the known risk factors for diabetes (age, obesity, family history of diabetes, history of a large newborn delivery); age but not body mass index appeared as a factor influencing HbA1c independently. In women, HbA1c levels rose particularly at the age of menopause but the use of oral contraceptives or oestrogens made no difference. In both sexes, HbA1c was higher in smokers than in non-smokers. No consistent seasonal variation was observed. Haematologic factors had a negligible influence on HbA1c level. HbA1c was more highly correlated with fasting plasma glucose than with 2 h-plasma/glucose (r = 0.20 vs 0.11). In a stepwise multiple regression analysis, age followed by fasting plasma glucose were the only two significant factors associated with the level of HbA1c. These data indicate that HbA1c is influenced only by factors closely linked to diabetes.
