"Hemicrania Episodica"-A New Type of Headache or a Pre-Chronic Stage of Hemicrania Continua?

For seventeen years, a young man suffered from headaches of one to three days duration occurring once every six or seven days and totally disappearing between episodes. These were strictly unilateral (always on the left side), and were absolutely responsive to indomethacin. They differ clinically from the other two indomethacin-responsive headaches described up to now: Hemicrania Continua (HC) and Chronic Paroxysmal Hemicrania (CPH). He has a sister suffering from HC. Similar to HC, but unlike CPH, topical tyramine in our patient's eyes resulted in anisocoria before, but not after, indomethacin treatment. Our case differs from HC, however, in its time pattern; it could either be a pre-chronic stage of HC or a new type of headache. It seems unlikely that a time pattern that has remained unchanged for 17 years will become continuous, as in HC, in the future, and thus it is possible that our patient represents a case of a new type of headache that we propose to name "Hemicrania Episodica." In any case, it seems probable that this type of headache, although clinically different, may share a common pathogenic basis with HC.     

Factors associated with insomnia symptoms: A cross-sectional study during a Covid-19 fully restrictive lockdown

Insomnia is the most frequent sleep disorder and a public health concern that increased during the Covid 19 pandemic. Fully restrictive lockdowns during Covid are interesting periods to examine the impact of environmental and behavioural changes on the emergence of insomnia symptoms. In this cross-sectional study we aimed to (1) determine the main factors associated with insomnia symptoms during a Covid-19 fully restrictive lockdown examining the associated daily life alterations and (2) create a predictive model of insomnia symptoms. We used the data drawn from the “Covid-RythmE” study that reached volunteers from the general French population through an online survey during the last 2 weeks of the 2 month full lockdown. Associations with insomnia symptoms were tested and significant associations were entered in a Backward Stepwise Logistic Regression (BSLR) to assess the best combination to classify individuals with or without insomnia symptoms. From the 1624 participants, 50.64% suffered from mild to severe insomnia symptoms as assessed by the ISI. The best combination for explaining insomnia symptoms with 74.26% of accuracy included: age (OR = 1.15), females (OR = 1.26), smaller home sizes (OR = 0.77), environmental noises (OR = 1.59), anxiety symptoms (OR = 1.24), depressive symptoms (OR = 1.15), regularity of sleep–wake schedules (OR = 1.25), exposure to screen during the morning (OR = 1.13), and LED light during the evening (OR = 1.17). Thus, lifestyle schedule and exposure to natural synchronizers such as light, are primordial in considering in insomnia physiopathology, prevention and treatment, as well as the associated mental health status.     

Vaginal hysterectomy: technique and results in the last twenty years

The objective of this work was to describe patient characteristics and the effect of vaginal hysterectomy in a University hospital in the last two decades. A retrospective review of women undergoing vaginal hysterectomy was performed. The type of hysterectomy and complications were determined. From 1974 to 1994, a total of 6420 hysterectomies were performed. The vaginal route was used for 1530 patients. In the last decade, the Heaney method was used. A comparison of the periods 1974-1984 and 1984-1994 revealed that with the Heaney technique, we had significantly fewer complications, including less febrile morbidity, bleeding requiring transfusion, and injuries. Vaginal hysterectomy, specially using the Heaney method, is a rewarding challenge for any gynecologic surgeon. There are a low postoperative morbidity rate and a low mortality rate, which is well below the average mortality rate associated with abdominal hysterectomy.     

The pattern of locomotor activity after cocaine treatment in the rat

The present study used a computerised technique to assess the behavioural effects on locomotor activity of i.p. cocaine administration in the rat. This computerised method provides considerable information about various behavioural responses, as well as accuracy by measuring the frequency and duration of every behavioural event. Cocaine induced an increase in behavioural events related to motor activity, such as moving, sniffing and rearing, while standing was reduced. Cocaine increased the frequency of the behavioural responses recorded, but decreased their mean duration. No stereotyped behavioural element, such as head swinging, head bobbing, licking, stereotyped mouth moving or stereotyped sniffing, was recorded after cocaine treatment. Cocaine, unlike d-amphetamine, induced a specific behavioural pattern characterised predominantly at all doses by a stimulated motor activation involving an increase in moving and sniffing and a decrease in standing behaviour.     

Side effects during continuous epidural infusion of morphine and fentanyl

Respiratory effects, nausea, somnolence, and pruritus were compared during a 48-hr period of continuous epidural morphine (n = 34) and fentanyl (n = 32) infusion in 66 patients following elective total replacement of the hip or knee joint. Respiratory effects were assessed by PaCO2. Side effects were assessed by visual analogue scale and considered to be present when the score was above 30. Assessment was made at preoperative visits then 3, 6, 12, 24, 36, and 48 hr after the epidural injection. The bolus dose and subsequent infusion rate were 3,900 +/- 1,300 micrograms and 427 +/- 213 micrograms.hr-1 for morphine, and 85 +/- 46 micrograms and 56 +/- 27 micrograms.hr-1 for fentanyl. Pain relief was similar in both groups. In the morphine group, PaCO2 elevation and nausea occurred over a period of more than 12 hr (P less than 0.05). In the fentanyl group, there was no PaCO2 change, and nausea was confined to the first few hours. Nausea was more severe (P less than 0.01 at six hours and more frequent (24 hr cumulative incidence, 53 vs 28%, P less than 0.05) in the morphine group. Somnolence was prominent within several hours in two-thirds of patients in both groups. Somnolence continued to decline thereafter in the morphine group, but it was demonstrable in approximately half of the patients throughout the second day in the fentanyl group. The incidence was higher in the fentanyl group at the 48th hr (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
