Effect of sleeping alone on sleep quality in female bed partners of snorers.

The aim of the present study was to objectively measure the effect of sleeping alone for one night on sleep quality in female bed partners of male snorers. Females complaining of poor sleep due to snoring by their bed partner and having no known hearing loss or snoring were included in a prospective multicentre cross-sectional study. 23 females underwent one polysomnography recording while sleeping with their bed partner and another while sleeping alone. Their sleep parameters were compared between the two nights. We excluded seven couples because the female partner snored for >10% of the sleep time (n = 6) or had obstructive sleep apnoea syndrome (n = 1). In the remaining 16 females, sleep time, sleep efficiency, arousal index and percentages of deep sleep (stages 3-4) and rapid eye movement (REM) sleep were not significantly different between the two nights. Percentages of light sleep (non-REM stage 2) and awakening index were lower when sleeping alone (p = 0.023 and p = 0.046, respectively). Sleep quality was decreased and sleep fragmentation increased in females sleeping with male snorers. Some females had unrecognised snoring. However, our data do not suggest that objective sleep quality improves substantially in the female nonsnoring partner when she sleeps alone for one night.

Relationships between endosonographic appearan e and clinical or manometric features in patients with achalasia.

BACKGROUND: The existence of endosonographic abnormalities of the oesophagus in achalasia is discussed. The place of endoscopic ultrasonography (EUS) needs to be clarified. PATIENTS: Thirty five untreated patients suffering from achalasia and 28 controls without oesophageal disease were prospectively enrolled since 1993. Pseudoachalasia was diagnosed in two patients. METHODS: EUS measurements were performed at two opposite sites at the level of the cardia, and 5 cm and 10 cm proximally, avoiding compression by the water filled balloon. RESULTS: The oesophageal wall and the fourth hypoechoic layer were significantly thicker at the level of the cardia and 5 cm above, with mean differences between patients and controls of 0.37/0.42 mm and 0.16/0.23 mm respectively. No statistically significant correlation could be demonstrated between the thickness of the oesophageal wall or of the fourth hypoechoic layer and weight loss, or the average pressure of the lower oesophageal sphincter. However, a significant inverse relationship was demonstrated between the duration of symptoms and the thickness of the fourth hypoechoic layer. The thickness of the fourth hypoechoic layer was also increased in patients who required only one pneumatic dilatation (P < 0.01). CONCLUSION: The thickness of the oesophageal wall and of the fourth hypoechoic layer appeared to be significantly increased in achalasia patients. However, the slight increase of the mean size (< 0.5 mm) of the muscularis propria suggests that EUS is not helpful in the diagnosis of achalasia. The physiopathological basis of advanced achalasia has to be reconsidered as we demonstrated an inverse relationship between the duration of symptoms and the thickness of the muscularis propria.

[Palliative treatment of esophageal neoplastic stenosis using bipolar electrocoagulation probe]. / Traitement palliatif des sténoses néoplasiques oesophagiennes par sonde d'électrocoagulation bipolaire (BICAP).

OBJECTIVE, PATIENTS AND METHODS: The objective of this study was to evaluate the results of palliative bipolar electrocoagulation probe (BICAP) treatment in 26 patients with non surgical, obstructive esophageal cancer. The mean tumor length was 7.2 cm. The strictures were located as follows: 3 in the cervical esophagus, 8 in the thoracic esophagus, 13 in the distal third of the esophagus and 2 involved both the cervical and thoracic esophagus. Most lesions were circumferential (73% versus 27% non circumferential) and exophytic (78% versus 22% sub mucosal). Coagulation was carried out under direct endoscopic control in the forward direction. The success of treatment was evaluated on the basis of the degree of reopening achieved (easy passage of an endoscope 12 mm in diameter) and good functional results (improvement of dysphagia, scored from 0 to 4 using a standard grading scale, for more than 15 days). RESULTS: Twenty-six patients underwent a total of 45 BICAP treatments (31 initial sessions, 14 repeated sessions). Reopening was achieved in 92% of cases and good functional results were obtained in 85% (mean dysphagia score: 3.2 before treatment versus 1.1 after treatment). The improvement of dysphagia resulted in a significant improvement of general performance status and stabilization or weight improvement in 21 patients. The mean number of sessions necessary for good initial results was 1.2 +/- 0.4. After the initial treatment by BICAP, radiotherapy or radiochemotherapy were respectively associated in 4 and 10 patients. The median duration of improvement was significantly longer in patients who underwent radiochemotherapy as compared with patients treated by BICAP alone (22 weeks versus 4 weeks). During the follow-up, 9 patients required several BICAP treatments and at the end of their disease, 12 patients underwent other palliative procedures. Major complications occurred in 4 cases (2 esotracheal fistulas, 1 hemorrhage, and 1 aspiration pneumonia) and mortality related to the procedure was 8%. CONCLUSIONS: Palliative BICAP treatment of obstructing esophageal and cardial cancer provide quick relief of dysphagia but repeated treatment sessions are necessary to maintain initial improvement. The procedure requires a short hospitalization stay and can be easily accomplished in all cases regardless of the tumor features.

[A case of pure unilobar Caroli disease]. / Un cas de maladie de Caroli pure, unilobaire.

We describe a new case of pure Caroli disease and review of the literature. Although often sporadic, this disease is usually considered an autosomal recessive hereditary disease. It is often either associated with another congenital hepatorenal fibrocystic disease or with extrahepatic bile duct dilatation. The clinical examination and laboratory tests are of not specific if congenital hepatic fibrosis or congenital cysts of the coleduct is lacking. Certain echographic and scan images are however very specific. Complications are related to intrahepatic stone formation and to superinfections. The long-term course appears to involve increased risk of cholangiocarcinoma. Treatment of the localized form includes priority resection. In diffuse disease, treatment may be more medical with antibiotics and sometimes bile solvents. In case of failure, transplantation may be entertained.
