[Lower urinary tracts symptoms after female genital mutilation: A review]. / Troubles fonctionnels du bas appareil urinaire après mutilation sexuelle féminine : revue de la littérature.

INTRODUCTION: The purpose of this article is to summarise the data available in literature on Lower Urinary Tract Symptoms [lower urinary tract symptoms (LUTS)] after female genital mutilation (MSF). METHODS: Our review identified 177 publications, 14 of which were included in the article. RESULTS: With regard to short-term complications, the prevalence of Acute Urinary Retention (RAU) after MSF is estimated between 3% and 12%. With respect to long-term complications, the data is discordant on repeat urinary tract infections (IUR) after MSF with an estimated prevalence between 9% and 39%. The prevalence of LUTS is significantly increased among women having suffered MSF. For example, mixed urinary incontinence is significantly higher in the MSF group with OR 5.17 CI 95% (2.34-12.97). And the more important the MSF is, the higher the LUTS prevalence is. Medical and surgical treatments are empirical and not evaluated. CONCLUSION: Further studies are needed to better characterize and evaluate the prevalence of LUTS after MSF as well as the interest and efficiency of different therapeutics.

'Vitamin D and cognition in older adults': updated international recommendations.

BACKGROUND: Hypovitaminosis D, a condition that is highly prevalent in older adults aged 65 years and above, is associated with brain changes and dementia. Given the rapidly accumulating and complex contribution of the literature in the field of vitamin D and cognition, clear guidance is needed for researchers and clinicians. METHODS: International experts met at an invitational summit on 'Vitamin D and Cognition in Older Adults'. Based on previous reports and expert opinion, the task force focused on key questions relating to the role of vitamin D in Alzheimer's disease and related disorders. Each question was discussed and voted using a Delphi-like approach. RESULTS: The experts reached an agreement that hypovitaminosis D increases the risk of cognitive decline and dementia in older adults and may alter the clinical presentation as a consequence of related comorbidities; however, at present, vitamin D level should not be used as a diagnostic or prognostic biomarker of Alzheimer's disease due to lack of specificity and insufficient evidence. This population should be screened for hypovitaminosis D because of its high prevalence and should receive supplementation, if necessary; but this advice was not specific to cognition. During the debate, the possibility of 'critical periods' during which vitamin D may have its greatest impact on the brain was addressed; whether hypovitaminosis D influences cognition actively through deleterious effects and/or passively by loss of neuroprotection was also considered. CONCLUSIONS: The international task force agreed on five overarching principles related to vitamin D and cognition in older adults. Several areas of uncertainty remain, and it will be necessary to revise the proposed recommendations as new findings become available.

Multiple cutaneous and uterine leiomyomatosis or reed syndrome: a retrospective study of 13 cases.

INTRODUCTION: Multiple cutaneous and uterine leiomyomatosis (MCUL), or Reed syndrome, is characterized by the presence of cutaneous leiomyomas arising from the arrector pili muscles and, in women, by uterine leiomyomas. In some cases, MCUL is associated with renal cell carcinoma. This syndrome is an autosomal dominant disorder caused by a heterozygous germline mutation of the gene that encodes fumarate hydratase, a Krebs cycle enzyme that acts as a tumor suppressor. OBJECTIVE: To review the cases of MCUL diagnosed at 2 university hospitals over a 5-year period (2008-2013). MATERIAL AND METHODS: This was a retrospective study of 13 cases of MCUL that investigated demographic, clinical, and histologic characteristics, as well as possible associations with other diseases and treatments received. RESULTS: We identified 13 patients (10 women and 3 men) who had been diagnosed with MCUL. The mean age at diagnosis was 53 years. All the patients had multiple cutaneous leiomyomas; in 12 (92%) the distribution was clustered and 9 (69%) also had disseminated solitary lesions. In 1 patient (7.7%), the pattern of distribution was linear. Uterine fibroids requiring hysterectomy were present in 90% of the women. Nine patients were screened for renal lesions; no cases of renal cell carcinoma were detected but benign renal lesions were found in 4 patients. CONCLUSION: The clinical and histologic characteristics of the 13 cases of MCUL reviewed were similar to those reported in the literature. The most common cutaneous manifestation was a type 2 segmental pattern. It is important for dermatologists to identify cutaneous leiomyomas and be aware of the possible association with MCUL.

Dermanyssus gallinae (chicken mite): an underdiagnosed environmental infestation.

Dermanyssus gallinae is a mite that normally parasitizes small birds but may occasionally bite humans. We report an unusual case of an 82-year-old woman who presented with pruritus and bite-like lesions over her trunk. Other members of the household were also affected. On physical examination, mites < 1 mm in size were found on the patient's body. The family were residing in the city centre and had no pets, but there were pigeon nests in close proximity to the house. Most dermatologists have difficulties identifying ectoparasitosis. In the case of D. gallinae, the small size of the mites and the fact that they leave the host after feeding means that they may not be seen at presentation, thus such infestations are likely to be underdiagnosed. Physicians should be aware that infection with this mite is possible even in patients from urban areas, and it should be included in the differential diagnosis of conditions causing recurrent pruritus unresponsive to standard treatments.

Compounding as a current therapeutic option in dermatology.

Compounding continues to play a key role in the treatment of skin conditions, despite the abundance of products made by the pharmaceutical industry. Right from the earliest days of dermatology, compounding proved very useful in the treatment of diseases for which no specific drugs were available. However, as new products came onto the market, this usefulness was called into question, and doubts over safety, stability, and effectiveness were raised. Today, compounding is regaining the place it once held in routine dermatological practice. We review the advantages and disadvantages of compounding, the most common indications, current legislation in our setting, and the latest developments in active ingredients and vehicles.

Nail psoriasis: treatment with tazarotene 0.1% hydrophilic ointment.

INTRODUCTION: Nail involvement is common in psoriasis and has a considerable impact on patient quality of life. Its clinical presentation depends on which part of the nail is affected: the bed or the matrix. Fifty percent of patients report associated pain. In this study, we analyzed the safety and effectiveness of tazarotene 0.1% in a hydrophilic ointment in the treatment of nail psoriasis. MATERIAL AND METHODS: We performed an open observational study of 6 patients diagnosed with nail psoriasis. The patients applied a compounded preparation of tazarotene 0.1% ointment under occlusion every night for 6 months in their homes. They were not receiving any other topical or systemic treatments. Nail psoriasis severity (assessed using the Nail Psoriasis Severity Index [NAPSI]), subungual hyperkeratosis, onycholysis, splinter hemorrhages, oil stains, and nail pitting were evaluated at baseline and at 3 and 6 months. RESULTS: A statistically significant improvement between baseline and 6 months was observed in all patients: the mean (SD) NAPSI went from 14.3 (6.3; 95% CI, 11.74-16.92) to 2.3 (1.21; 95% CI, 1.84-2.3) while the median went from 15 to 2.5 (P = .007). The percentage improvement at the end of treatment was 87.9%. No adverse effects were observed. CONCLUSION: Our study shows the therapeutic potential of tazarotene ointment in nail psoriasis.

Changing species distribution and antimicrobial susceptibility pattern of Shigella over a 29-year period (1980-2008).

We studied changes in species distribution and antimicrobial resistance patterns of Shigella during 1980-2008, using the Diarrhoeal Diseases Surveillance system of Dhaka Hospital of ICDDR,B. In hospitalized patients Shigella prevalence decreased steadily from 8-12% in the 1980s to 3% in 2008. Endemic S. flexneri was the most commonly isolated species (54%). Epidemic S. dysenteriae type 1 had two peaks in 1984 and 1993, but was not found after 2000, except for one case in 2004. The therapeutic options are now limited: in 2008 a total of 33% of S. flexneri were resistant to ciprofloxacin and 57% to mecillinam. In the <5 years age group, severely underweight, wasted and stunted children were more at risk of shigellosis compared to well-nourished children (P<0·001). Although hospitalization for Shigella diarrhoea is decreasing, the high levels of antimicrobial resistance and increased susceptibility of malnourished children continue to pose an ongoing risk.

Protection against Plasmodium falciparum malaria in chimpanzees by immunization with the conserved pre-erythrocytic liver-stage antigen 3.

In humans, sterile immunity against malaria can be consistently induced through exposure to the bites of thousands of irradiated infected mosquitoes. The same level of protection has yet to be achieved using subunit vaccines. Recent studies have indicated an essential function for intrahepatic parasites, the stage after the mosquito bite, and thus for antigens expressed during this stage. We report here the identification of liver-stage antigen 3, which is expressed both in the mosquito and liver-stage parasites. This Plasmodium falciparum 200-kilodalton protein is highly conserved, and showed promising antigenic and immunogenic properties. In chimpanzees (Pan troglodytes), the primates most closely related to humans and that share a similar susceptibility to P. falciparum liver-stage infection, immunization with LSA-3 induced protection against successive heterologous challenges with large numbers of P. falciparum sporozoites.

Serum prolactin levels in psoriasis and correlation with cutaneous disease activity.

BACKGROUND: Prolactin (PRL), a neuropeptide secreted by the anterior pituitary gland, possesses a variety of physiological actions. It has been implicated as an important immunomodulator and exerts a proliferative effect in cultured human keratinocytes via specific receptors. Some studies have indicated an increase in serum PRL levels in psoriasis and exacerbation of psoriasis when a prolactinoma is present. AIM: To evaluate the correlation between serum PRL levels and Psoriasis Area and Severity Index (PASI). METHODS: Serum PRL levels were measured in 20 patients (10 mean, 10 women, age range 18-88 years) with plaque-type psoriasis before and after a 6-week period of topical treatment with tacalcitol ointment. Results were compared with a group of 20 healthy volunteers. RESULTS: Serum PRL levels were significantly increased in the psoriatic group compared with the control group (P < 0.001) and were significantly reduced after treatment (P = 0.001). There was a correlation between pretreatment serum PRL levels and PASI (r = 0.33; P = 0.02). CONCLUSIONS: These results indicate that serum PRL levels may serve as a biological marker of psoriatic disease activity.

Nail psoriasis: a retrospective study on the effectiveness of systemic treatments (classical and biological therapy).

BACKGROUND: Nail psoriasis represents a challenge for specialists. There is no comparative study of systemic treatment's effectiveness at this site. OBJECTIVE: Evaluate the response of nail psoriasis to classical and biological therapy and to compare the effectiveness and safety of the different treatments. METHODS: We performed a retrospective study of 84 patients with moderate-severe psoriasis seen at our Department between January 2006 and January 2009. RESULTS: Psoriasis was severe in 53.4%. In 75% of cases, the fingernails were affected, and the mixed form was the most frequently subtype. The mean baseline scores on the PASI and the NAPSI were 23.12 and 14.7 respectively; the correlation between the two scores fell at weeks 12 and 24 but had risen again at week 48. The baseline NAPSI score tended to be lower in women and significantly higher in patients over 65 years of age, family history of psoriasis, severe psoriasis and nail matrix involvement. In our series, 58.3% received classical treatment (acitretin, methotrexate, cyclosporin, PUVA, NUVB, REPUVA, RENUVB) and 41.7% received biological treatment (infliximab, efalizumab, etanercept, adalimumab).Significant reductions were found (P < 0.05) in the mean NAPSI scores at 12, 24 and 48 weeks with all the antipsoriatic agents except NUVB; significantly greater with cyclosporine (P < 0.01) and biological as infliximab and adalimumab at 12 and 24 weeks (differences between treatments disappeared at 48 weeks). CONCLUSION: The response to treatment is slower in the nail lesions than in the skin lesions. The improvement of nail psoriasis is significant both with the classical treatments significantly higher in cyclosporin; and biological treatment (infliximab and adalimumab at 12 and 24 weeks).

[Guidelines for Clinical Practice of the French College of Obstetricians and Gynecologists 2021: Prophylactic procedures associated with gynecologic surgery]. / Recommandations pour Pratique Clinique du Collège des Gynécologues Obstétriciens français 2021 : gestes prophylactiques associés en chirurgie gynécologique.

OBJECTIVE: To draw up recommendations on the use of prophylactic gynecologic procedures during surgery for other indications. DESIGN: A consensus panel of 19 experts was convened. A formal conflict of interest policy was established at the onset of the process and applied throughout. The entire study was performed independently without funding from pharmaceutical companies or medical device manufacturers. The panel applied the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system to evaluate the quality of evidence on which the recommendations were based. The authors were advised against making strong recommendations in the presence of low-quality evidence. Some recommendations were ungraded. METHODS: The panel studied 22 key questions on seven prophylactic procedures: 1) salpingectomy, 2) fimbriectomy, 3) salpingo-oophorectomy, 4) ablation of peritoneal endometriosis, 5) adhesiolysis, 6) endometrial excision or ablation, and 7) cervical ablation. RESULTS: The literature search and application of the GRADE system resulted in 34 recommendations. Six were supported by high-quality evidence (GRADE 1+/-) and 28 by low-quality evidence (GRADE 2+/-). Recommendations on two questions were left ungraded due to a lack of evidence in the literature. CONCLUSIONS: A high level of consensus was achieved among the experts regarding the use of prophylactic gynecologic procedures. The ensuing recommendations should result in improved current practice.

[Imported malaria in University Hospital Center of Bordeaux, France, 2000-2007. A comparison study with the French national epidemiological data]. / Le paludisme d'importation au CHU de Bordeaux de 2000 à 2007: épidémiologie, prise en charge et comparaison avec les données nationales.

In Western countries, France accounts for the most concerned by imported malaria. The objective of the present study was to describe the epidemiological and clinical features of imported malaria in adults attending the University Hospital Center (UHC) ofBordeaux and to compare these findings with the French national epidemiological data. A retrospective analysis of all patients aged over 15 years with parasitologically confirmed malaria in patients recruited between January 1, 2000 and December 31, 2007 has been performed. A total of 526 cases fitted the inclusion criteria with two-thirds of males and a mean age of 37 years. Patients were less frequently native from sub-Saharan Africa (SA), Madagascar, and Comoros than those from the French national data register (29 versus 72%). Hence, SA was the main destination (2/3 travelling to Western Africa and 1/3 to Central Africa). The recourse to an adequate chemoprophylaxis (CPL) for stays in areas of chemoresistance had been reported in about one-third of the patients. From these, two thirds were noncompliant. The recourse to chloroquine less frequent (6 versus 24%) among patients from Bordeaux compared to those from the national data register whereas the recourse to mosquito net use more frequent in patients from Bordeaux (36 versus 3%). Plasmodium falciparum was the main infective species.Malaria was more frequently associated with hospitalization (89 versus 71%) and with severe disease (9 versus 4%) in Bordeaux than in national data register. Two deaths were declared. Atovaquone-proguanil (AP) combination therapy wasmore frequently used in Bordeaux compared to the national data (64 versus 20%). This AP combination treatment was the most frequently prescribed for uncomplicated malaria, whereas intravenous quinine was mainly used for complicated malaria and for patients with vomiting. The lack of CPL, the diagnosis or therapeutic delay, and the lethality of malaria among travellers infected by malaria imported from SA argue for the implementation of continuing medical training and health education targeted at travellers from France to high malaria-endemic areas such as SA, Madagascar, and Comoros.

[Bullous scabies responding to ivermectin therapy]. / Sarna ampollosa con respuesta terapéutica a la ivermectina.

Bullous scabies is a rare disease that is usually diagnosed in elderly patients. The clinical, histological, and immunological findings are identical to bullous pemphigoid. In a review of the literature, we found reports of 24 cases. We present a new case of bullous scabies in a 72-year-old man. The lesions responded to treatment with oral ivermectin.

Systematic review of guidelines for urinary incontinence in women.

INTRODUCTION AND OBJECTIVE: Urinary incontinence in women is the subject of multiple recommendations all over the world. The aim of our study was to compare methodologies and search for inconsistencies in texts and grades in these guidelines. METHODS: Seventeen recommendations from different medical societies in English, French and German were included. Their methodologies were analyzed, including writing methods, cyclicity, level of evidence (LE) and grades. The recommendations were synthesized and inconsistencies in texts and grades were studied. The quality of recommendations was evaluated with the Appraisal of Guidelines for Research and Evaluation (AGREE II) scale. RESULTS: Methods, rigour and cyclicity varied depending on societies. LE and grades are broadly consensual for higher LE and grades and less so for lower LE and grades. The Collège National des Gynécologues et Obstétriciens Français, the Deutsche Gesellschaft für Gynäkologie und Geburtshilfe, the European Association of Urology, the International Consultation on Urological Diseases and the National Institute for Health and Care Excellence have an AGREE score ≥ 80 % (third quartile). Grading and textual inconsistencies are explained by the order of studies or the absence of high LE. CONCLUSION: With the present study we closely explored comparatively the methods and semantics of recommendations for urinary incontinence in women.

Inability of malaria vaccine to induce antibodies to a protective epitope within its sequence.

Saimiri monkeys immunized with a recombinant protein containing 20 copies of the nine amino acid repeat of the Plasmodium vivax circumsporozoite (CS) protein developed high concentrations of antibodies to the repeat sequence and to sporozoites, but were not protected against challenge. After intravenous injection of an immunoglobulin G3 monoclonal antibody (NVS3) against irradiated P. vivax sporozoites, four of six monkeys were protected against sporozoite-induced malaria, and the remaining two animals took significantly longer to become parasitemic. Epitope mapping demonstrated that NVS3 recognizes only four (AGDR) of the nine amino acids within the repeat region of the P. vivax CS protein. The monkeys immunized with (DRAADGQPAG)20 did not produce antibodies to the protective epitope AGDR. Thus, determination of the fine specificity of protective immune responses may be critical to the construction of successful subunit vaccines.

It is true Artemisia.

There is currently a hazardous debate between the rational use of antimalarial drugs based on artemisinin derivatives and the antimalarial efficacy of plant extracts of Artemisia spp. This article recall some fundamental rules guiding progresses in malaria treatment and use of artemisinin, with the aim to provide discussion elements to identify the safest place responding to health situations for drugs and phytotherapy.

Calcium phosphate powder synthesis by out-of-phase pulsed sonoelectrochemistry.

High aspect ratio calcium phosphate (CaP) nanorods were achieved by out-of-phase pulsed sonoelectrodeposition from electrolytic aqueous bath composed of calcium nitrate, ammonium dihydrogenophosphate and surfactant at pH of 4.9. The nature of CaP phases was determined by powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray spectroscopy (EDX). The results reveal the predominantly presence of calcium deficient hydroxyapatite (CDHA). The transmission electron microscopy (TEM) analyzes highlighted that the nanorods are polycristalline and have an aspect ratio up to 30.

Nail psoriasis: a combined treatment with 8% clobetasol nail lacquer and tacalcitol ointment.

BACKGROUND: Nail involvement is a common and distressing feature in the course of psoriasis. Although much progress has been made in the treatment of the disease, the presence of psoriasis in the nail continues to pose a challenge. In recent years, vitamin D3 analogs and a new formulation containing 8% clobetasol-17-propionate in a colourless nail lacquer vehicle have produced good results for the control of nail psoriasis. OBJECTIVE: To determine the efficacy and safety of the combined treatment of 8% clobetasol-17-propionate in a lacquer vehicle and tacalcitol ointment in nail psoriasis. METHODS: Fifteen patients with both nail bed and nail matrix psoriasis were included in the study. They were treated with a colourless nail lacquer containing 8% clobetasol-17-propionate applied at bedtime at the weekend, and with tacalcitol ointment under occlusion on the remaining days, for 6 months. RESULTS: All 15 patients responded well to treatment. The therapeutic effect was very fast and directly related to the length of therapy. All nail alterations, including nail pain, were reduced, and the modified target Nail Psoriasis Severity Index fell by an average of 78% compared to baseline levels (+/-59.6, P < 0.0001). CONCLUSIONS: Combined treatment with tacalcitol ointment and 8% clobetasol-17-propionate in a nail lacquer is a safe, effective treatment for nail bed and nail matrix psoriasis.

[Instrumental extractions using Thierry's spatulas: evaluation of the risk of perineal laceration according to occiput position in operative deliveries]. / Extraction instrumentale par spatules de Thierry: évaluation du risque périnéal en fonction du dégagement.

OBJECTIVE: Risk factors for severe perineal lacerations are nowadays well-known and they include operative vaginal deliveries and extractions in occiput posterior (OP) positions. The aim of this study was to assess whether OP position increases the risk for anal sphincter injury when compared with occiput anterior (OA) positions in operative deliveries using Thierry's spatulas. METHODS: Retrospective study of 163 extractions with Thierry's spatulas over a five-year period (January 2000 to December 2005) performed in a general hospital. Singleton cephalic pregnancies at term were studied and the incidence of severe perineal lacerations was noted in deliveries in OP and OA positions. RESULTS: In these 163 cases, the varieties of presentation obtained by vaginal examination were 129 in anterior and 34 in posterior positions. Eleven posterior positions rotated anteriorly on delivery and 23 remained in a posterior position. The OA group (n=140) and the OP group (n=23) were constituted. Anal sphincter injury occurred significantly more often in the OP group compared with the OA group (17.4% versus 2.9%, p=0.014) with an odds ratio of 7.1 (95% CI 1.6-31). Only one fourth-degree laceration was noted. Within the OP group, the incidence of vaginal lacerations was increased compared to the OA group, but without any significant difference (43.5% versus 27.9%, p=0.20). In a logistic regression model, the OP position was 6.4 times (95% CI 1.3-31.5) more likely to be associated with anal sphincter injury than OA position. The incidence of OP position was 14.1% within the whole population studied and Thierry's spatulas permit anterior rotations of occipito posterior presentation in only 32.4% of cases. CONCLUSION: The efficiency of Thierry's spatulas is proven. As with forceps and vacuum extractors, extraction with Thierry's spatulas is a risk factor for perineal laceration compared to a spontaneous delivery. In deliveries with spatulas, OP head positions further increase this perineal risk against OA positions. OP positions before fetal extractions do not seem to be an ideal situation for using spatulas, even if an anterior rotation is achieved in one-third of cases.
