[Tentatives de suicide au Maroc: une revue systématique]

BACKGROUND

Suicide is a widespread phenomenon that affects persons of all ages, and it has become a major public health problem in Morocco.

OBJECTIVES

This study aims to describe the epidemiological profile of suicide attempters in Morocco, as well as the identification of associated factors.

METHODS

The present work is a systematic review that was conducted according to the recommendations of the "Preferred reporting items for systematic reviews and meta-analysis (2009)", including articles dealing with suicide attempts in Morocco that meet the usual inclusion criteria. The PubMed, ScienceDirect and Scopus databases were searched; articles had to be written in English or French. Additional studies were manually identified through via Google Scholar. Quality assessment of the included studies was carried out according to the NIH Assessment Tool. The review protocol was registered in PROSPERO (CRD42020165493).

RESULTS

Twenty studies were selected. Adults and adolescents are the age groups most affected by suicide. That said, the phenomenon mainly concerns children over 10 years of age. In some studies, more than 90% of the cases involve females, and they are more numerous in urban than in rural settings, and single individuals are more affected than married people. As for children and adolescents, most of them had divorced parents, and more than 50% of suicidal persons of all ages had a low socio-economic level. Although females are more likely than males to commit suicide, males are more exposed to death due to the violent means used.

CONCLUSIONS

Because of the alarming rate of suicide in our country, nationwide prevention strategies are called for.

Monoamine Oxidase Inhibition by Plant-Derived β-Carbolines; Implications for the Psychopharmacology of Tobacco and Ayahuasca

The monoamine oxidases (MAOs) are flavin-containing amine oxidoreductases responsible for metabolism of many biogenic amine molecules in the brain and peripheral tissues. Whereas serotonin is the preferred substrate of MAO-A, phenylethylamine is metabolized by MAO-B, and dopamine and tyramine are nearly ambivalent with respect to the two isozymes. β-Carboline alkaloids such as harmine, harman(e), and norharman(e) are MAO inhibitors present in many plant materials, including foodstuffs, medicinal plants, and intoxicants, notably in tobacco (Nicotiana spp.) and in Banisteriopsis caapi, a vine used in the Amazonian ayahuasca brew. The β-carbolines present in B. caapi may have effects on neurogenesis and intrinsic antidepressant properties, in addition to potentiating the bioavailability of the hallucinogen N,N-dimethyltryptamine (DMT), which is often present in admixture plants of ayahuasca such as Psychotria viridis. Tobacco also contains physiologically relevant concentrations of β-carbolines, which potentially contribute to its psychopharmacology. However, in both cases, the threshold of MAO inhibition sufficient to interact with biogenic amine neurotransmission remains to be established. An important class of antidepressant medications provoke a complete and irreversible inhibition of MAO-A/B, and such complete inhibition is almost unattainable with reversible and competitive inhibitors such as β-carbolines. However, the preclinical and clinical observations with synthetic MAO inhibitors present a background for obtaining a better understanding of the polypharmacologies of tobacco and ayahuasca. Furthermore, MAO inhibitors of diverse structures are present in a wide variety of medicinal plants, but their pharmacological relevance in many instances remains to be established.

[Literature review on pharmacovigilance of medicines derived from traditional pharmacopoeias. Part I: risks identification]

Globally, the use of drugs from traditional pharmacopoeias is a major subject. The confidence of the populations in these drugs is linked to their presumption of safety and also to the fact that geographically and financially they are more accessible than synthetic drugs. In view of the high exposure of the world population to traditional medicines, they are subject to pharmacovigilance guaranteeing their safety in use. Thus, this review aims to take stock of the risks identified by the national pharmacovigilance systems. It is based on research referenced in PubMed, Embase, ScienceDirect and GoogleScholar. These studies indicate that the use of traditional drugs can involve risks including adverse effects, interactions with synthetic drugs, adulteration and contamination. The spontaneous notification system was the basis for their identification. Strengthening this system and making populations aware of these risks constitute the key levers for traditional medicines pharmacovigilance progress.

Fatal poisoning of pregnant women by peganum harmala L.: A case reports

Introduction

Peganum harmala L. is a cosmopolitan plant within the Mediterranean region. It's normally employed in ancient drugs in Morocco as sedative and abortifacient however exposes users to the danger of dose and poisoning. The medical specialty active compounds of this plant embody variety of carboline and quinazoline alkaloids accountable of its pharmacological and medical effects.

Case report

We tend to report the case of a 20-year-old woman, intoxicated with the Peganum harmala L. On admission, she was shocked with agitation vomittiong and disturbances of consciousness. Laboratory tests showed anemia, thrombocytopenia, acute kidney disease, increase in transaminases and a positive plasma bHCG. Cerebral CT disclosed multiple areas of cerebral ischemia with subarachnoid hemorrhage, thoraco-abdominal-pelvic CT scan showed an enlarged uterus, the location of an interior hemorrhage while not physiological condition sac and inhalation pneumonia. Early treatment was given, she was intubated, ventilated artificially and sedated, symptomatic treatment was received. Hemodialysis was needed for her renal failure and anuria. She was extubated after six days and discharged from the hospital after one month and a half.

Conclusion

Doctors operating in areas where P. harmala is prescribed or used as an ancient medicine should recognize the signs and symptoms of its toxicity in order to treat and initiate prompt and adequate management. The prognosis is generally favorable, excessive use of high doses of P. Harmala L. can lead to fatal evolution.

The Peganum harmala L. is a cosmopolitan plant within the Mediterranean region, which normally employed in ancient drugs in Morocco as sedative and abortifacient

-

Excessive dose use of Peganum hamrmala L. by the pregnant women exposes to the danger of fatal poisoning

-

The treatment of this intoxication is generally symptomatic and there is no antidote specific.

-

The prognosis of poisoning of pregnant women by Peganum harmala L. is generally favorable.

Potential Risks of Plant Constituents in Dietary Supplements: Qualitative and Quantitative Analysis of Peganum harmala Seeds

The free online trading of herbal mixtures useful for various purposes facilitates the circulation of dangerous herbs or plant parts. This is the case, for example, of the illegal trade in seeds of Peganum harmala (Pgh), which contain alkaloids capable of inhibiting monoamine oxidase (MAO) and are therefore used in hallucinogenic preparations, such as the psychedelic drink ayahuasca. The precise identification of these seeds and their distinction from other very similar but not dangerous seeds are necessary for forensic purposes and represents an advance in avoiding the adulteration of mixtures. In this work, we show the qualitative identification of Pgh seeds by optical and electron microscopy and the parallel development of a real-time qPCR test, which reveals, in a species-specific manner, the presence of Pgh DNA up to quantities lower than 1 pg. In addition to the species specificity and high sensitivity, the reaction accurately quantifies the presence of seeds or parts of seeds of Pgh in complex herbal mixtures, thus giving an indication of the danger or otherwise of the product.

Peganum harmala L. Intoxication in a Pregnant Woman

Peganum harmala L. is a plant widely distributed in the Mediterranean region. It is commonly used in traditional medicine in Morocco as sedative and abortifacient but exposes users to the risk of overdose and poisoning. The pharmacologically active compounds of this plant include a number of β -carboline and quinazoline alkaloids responsible of its pharmacological and toxicological effects. We report the case of a 24-year-old woman, 22 weeks pregnant, intoxicated with the seeds of Peganum harmala L. On admission, she had disturbance of consciousness, uterine contraction, and oliguria. Laboratory tests revealed renal failure and liver injury, and she benefited then from hemodialysis. During hospitalization, she was intubated after deterioration of consciousness and presented a spontaneous expulsion of the fetus. After extubation, she kept unusual sequelae: cerebellar ataxia and peripheral polyneuropathy. Physicians in regions using Peganum harmala L. as traditional medicine must be able to detect symptoms of its toxicity, in order to establish early gastrointestinal decontamination. The prognosis of this intoxication is variable; most cases can be managed successfully; but in high doses of intoxication, evolution can be fatal.

Al-Akhawayni, a contributor to medieval Persian knowledge on contraception

Modern scientific achievements in the field of contraception are clearly indebted to past studies. Al-Akhawayni Bukhari was a Persian physician in the 10th century. He lived during the 'Golden Age of Islamic Medicine' (9th to 12th century AD). This scientist recorded his knowledge on various medical matters, including contraception, in the book 'Hidayat al-Muta`allemin Fi al-Tibb' (Learner's Guide to Medicine). These 10th century views on contraception are explored in this paper through a discussion of Al-Akhawayni Bukhari's surviving book, the 'Hidayat' (Guide).
