Cerebral blood flow in just detoxified alcohol dependent patients. A 99 m Tc-HMPAO-SPECT study.

Chronic alcohol abuse is responsible for several organic brain disorders. However, even the most characteristic of them are largely underdiagnosed by routine procedures. Therefore, there is need for sensitive, noninvasive and low-cost diagnostic procedures. 99m-Tc-HMPAO-SPECT could be an interesting candidate in this indication, because it estimates the distribution of the cerebral blood flow and the metabolic activity of the brain with a good resolution. We used this technique in 17 healthy volunteers and in a sample of 50 patients dependent on alcohol, without other major physical or mental disorder. SPECT was performed during the attendance of these patients in an inpatient detoxification program. We observed abnormal SPECT in 34 patients, but only in 2 volunteers (p < 0.001). The main abnormality was heterogeneity of the distribution of the tracer. SPECT abnormalities appear to be due nor to withdrawal syndrome, nor to medication. On the contrary, they are correlated with stigmata of heavy alcoholism. Furthermore, a genetic vulnerability to alcohol was suspected because SPECT abnormalities are more frequent in patients with an history of drinking problems in their relatives.Journal Articleinfo:eu-repo/semantics/publishe

Central and Peripheral Nervous System Disorders Following Ivermectin Mass Administration: A Descriptive Study Based on the Democratic Republic of Congo Pharmacovigilance System.

Introduction: The mainstay of onchocerciasis control currently is mass administration of ivermectin; however, this may be associated with serious adverse events, including deaths, when administered in areas where onchocerciasis and loiasis are co-endemic. Objectives: The objective of the current study was to describe the central and peripheral nervous system disorders that occurred after mass administration of ivermectin in Democratic Republic of Congo (DRC). Methods: This is a retrospective descriptive study involving a review of data on adverse events related to mass administration of ivermectin. Data on reported serious adverse events following mass administration of ivermectin in the DRC were extracted from the World Health Organization (WHO) Global individual case safety report (ICSR) database (VigiBase). The review covered the period 2009–2013 and focused on central and peripheral nervous system disorders. Relevant demographic, clinical, and parasitological data, including age, sex, area of residence, adverse events, and parasite density were extracted. Descriptive statistics were analyzed using Stata 12. Results: A total of 52 ICSRs related to ivermectin intake were available in VigiBase, with 51 (98.1%) from the Province of Equateur. All patients had central and peripheral nervous system disorders; 25 (48.1%) had altered mental status. Of these, 23 (92.0%) satisfied the criteria for “probable/possible Loa loa encephalopathy temporally related to mectizan®” (PLERM). The most frequent nervous system disorders among patients with PLERM were coma (74%), stupor (30%), headache (22%), and abnormal gait (22%). There were, on average, 2149.1 microfilariae per ml (mf/ml) in peripheral blood [95% confidence interval (CI) 463.6–3834.6; n = 23]. Post-treatment, 61% of PLERM cases had <1000 L. loa mf/ml of blood. One patient had microfilariae in the cerebrospinal fluid rather than the peripheral blood. We found 21.4% co-infection with Plasmodium falciparum and 4% mortality. Conclusion: PLERM may occur at even low peripheral blood concentrations of microfilaria.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Mesure du débit sanguin cérébral régional par une méthode radio-isotopique utilisant la tomoscintigraphie par émission monophotonique du 99mTc-HMPAO et le compteur humain total

We propose an atraumatic tomoscintigraphic method using cerebral 99mTc-HMPAO retention measured in a whole body counter (WBC) for absolute regional cerebral blood flow measurement (mL/min/100 g). Measurements concern 25 alcoholics in treatment for alcohol withdrawal, at the first ant the third week of hospitalisation. Results are compared with those of a 133Xe inhalation method; for the frontal and parietal ROI no difference was observed between the right side and the left side, nor between the 1st and the 3rd week of observation, whatever the method utilized.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Sleep in detoxified alcoholics: impairment of most standard sleep parameters and increased risk for sleep apnea, but not for myoclonias--a controlled study.

OBJECTIVE: To assess recently alcohol-abstinent chronic alcoholic patients for selected parameters indicative of sleep quality. METHOD: Patients (n = 24, 14 male), abstinent 3-6 weeks, and healthy controls (n = 20) were admitted to a clinical sleep unit. Measurements included sleep respiratory events and periodic limb movements, using strict methodology. RESULTS: Clear signs of sleep deterioration and a high prevalence of apneic/hypopneic episodes were observed. Apneas were found at the same frequency for men and women; this has not been described before. No periodic limb movement was found. CONCLUSIONS: Considering the high degree of morbidity and mortality observed in sleep apneic syndrome, systematic screening for sleep apneas is recommended for alcoholics seeking help.Journal Articleinfo:eu-repo/semantics/publishe
