The use of illicit drugs as self-medication in the treatment of cluster headache: Results from an Italian online survey.

BACKGROUND: Cluster headache (CH) patients often receive unsatisfactory treatment and may explore illicit substances as alternatives. We aimed to explore this use of illicit drugs for CH treatment. METHODS: We invited CH patients from an Internet-based self-help group to complete a questionnaire regarding their therapeutic use of illicit substances. RESULTS: Of the 54 respondents, 29 were classified as chronic and 39 were drug-resistant cases. Fifty patients had previously tried subcutaneous sumatriptan, 40 had tried O2, and 48 had tried at least one prophylactic treatment. All 54 patients specified that they were dissatisfied with conventional treatments. Thirty-four patients had used cannabinoids, 13 cocaine, 8 heroin, 18 psilocybin, 12 lysergic acid amide (LSA), and 4 lysergic acid diethylamide (LSD). DISCUSSION: Some patients with intractable CH decided to try illicit drugs concomitantly with cessation of medical care. Most of these patients found suggestions for illicit drug use on the Internet. Many patients seemed to underestimate the judicial consequences of, and had an overestimated confidence in the safety of, such illicit treatments. Physicians are often not informed by patients of their choice to use illicit drugs. This leads to questions regarding the true nature of the physician-patient relationship among dissatisfied CH patients.

Migraine improvement during short lasting ketogenesis: a proof-of-concept study.

BACKGROUND AND PURPOSE: Ketogenesis is a physiological phenomenon due to starvation or a ketogenic diet (KD), a drastic restricted carbohydrate dietary regimen that induces lipid metabolism and ketone body synthesis. Two patients whose migraines disappeared only during, and not outside, cycles of very-low-calorie KD performed to reduce their weight were recently observed. To confirm our observation, in a dietitian clinical setting two parallel groups of migraineurs, one receiving a 1-month very-low-calorie KD prescription followed by a 5-month standard low-calorie diet (SD) and the other a 6-month SD, were followed. METHODS: Ninety-six overweight female migraineurs were enrolled in a diet clinic and blindly received a KD (n = 45) or an SD (n = 51) prescription. Mean monthly attack frequency, number of days with headaches and tablet intake were assessed before and 1, 2, 3 and 6 months after diet initiation. RESULTS: In the KD group, the baseline attack frequency (2.9 attacks per month), number of days with headaches (5.11 days per month) and tablet intake (4.91 doses per month) were significantly reduced after the first month of diet (respectively 0.71, 0.91, 0.51; overall, KD versus baseline, P < 0.0001). During the transition period (first versus second month), the KD group showed a transient worsening of each clinical headache variable (respectively 2.60, 3.60, 3.07), despite being improved compared with baseline, with continuous improvement up to month 6 (respectively 2.16, 2.78, 3.71). In the SD group, significant decreases in the number of days with headaches and tablet intake were observed only from month 3 (P < 0.0001), and in attack frequency at month 6 (P < 0.0001). CONCLUSIONS: The underlying mechanisms of KD efficacy could be related to its ability to enhance mitochondrial energy metabolism and counteract neural inflammation.

Effect of pravastatin on endothelial function and endothelial progenitor cells in healthy postmenopausal women.

PURPOSE: Coronary heart disease is the leading cause of morbidity and mortality in postmenopausal women. Among statins, pravastatin has been shown to significantly reduce fatal and non-fatal cardiovascular events in primary and secondary prevention trials. The aim of the present research was to investigate whether treatment with pravastatin can modify some indices of cardiovascular risk in healthy postmenopausal women such as significant reductions in total and LDL cholesterol and triglyceride levels. METHODS: 20 patients were randomized in double-blind fashion to treatment for eight weeks with either pravastatin 40 mg/day or placebo, and subsequently, after one-week wash-out, crossed-over to the alternative treatment (placebo or pravastatin) for the following eight weeks. We performed clinical and laboratory investigations, before and at the end of each treatment period, to evaluate patient response to the treatment with pravastatin. RESULTS: After eight weeks pravastatin therapy reduced the median low density lipoprotein (LDL) and total cholesterol (p < 0.01 in both cases). In contrast, insulin level and insulin sensitivity did not show any difference with regard to values observed after placebo treatment. The absolute number of endothelial progenitor cells-colony forming unit (EPC-CFU) was significantly increased by pravastatin treatment (30.6% increase, p < 0.05) and the number of senescent cells was significantly decreased. However pravastatin did not increase tube-like formation by EPC and did not improve endothelial function. CONCLUSIONS: Despite beneficial effect on lipids and EPC, short term pravastatin does not seem to improve other cardiovascular risk factors, at least in healthy postmenopausal women.

[Role of vaginal infection in fetal and neonatal mortality]. / Ruolo delle infezioni vaginali nella mortalità fetale e neonetale.

Preterm delivery is the chief problem in obstetrics today and the main determinant of infant mortality and morbidity. Despite the dramatic decrease in infant mortality rate during the past several years, the percentage of preterm (<37 weeks gestation) and low birth weight (LBW) (<2500) rates remain elevated. Approximately 10% of all births are preterm, with a rate of 1-2% of infant born before the end of the 32 weeks of gestation and with a weight <1500 g. Despite the importance of the problem, the majority of preterm live births remain unexplained, and programmatic attempts at reversing the high level of preterm births have not been successful. Numerous studies have linked bacterial vaginosis, chorioamniotitis and endometritis with preterm birth and LBW, especially among African women. The number of preterm live births among African women is twice the one among Caucasians. Bacterial vaginosis is an independent risk factor for preterm and LBW births and the mechanism by which bacterial vaginosis causes the preterm birth of an infant with LBW is unknown. The aim of this article was to underline the importance of the treatment and early identification of vaginal infection, in particular if due to bacterial vaginosis, as it can have a substantial affect on the incidence of preterm delivery with LBW.
