Actinic keratosis (AK) are scaly lesions caused by chronic ultraviolet-induced damage to the epidermis which are a proxy for excessive sun-exposure [1] that may evolve into squamous cell carcinoma [2-7]. Therefore, there is a need or continuous surveillance of such patients along with adapted information for an effective photo-protection, practical couselling on photoprotection towards the defined population, i.e. elderly with actinic keratosis. Thus, patient observance and adhesion to the dermatologist recommendations become a real public health issue. In this context, we aimed to evaluate through a non-interventional, real-life observational study, the impact of photoprotection counseling by the dermatologist on patients attitude towards sun exposure

A thought-provoking debate in the popular literature concerning vaccination has blossomed in recent years [1-6]. While “traditionalists” support universal immunization against a variety of infectious diseases, many influential individuals hold that vaccinations do far more harm than good. The web sites vactruth.com and anhinternational.org are typical web sites to visit to understand their concerns.  More details on the debate, offering commentary on both sides of the issue, can be explored at wikipedia.org/wiki/Vaccine_controversies. In essence, however, those arguing for the universal use of vaccines point to the many millions of lives saved since mass immunization programs were introduced and further argue that resistance to routine vaccination is almost always based on false information. Those arguing against the routine use of vaccines usually either contend that the vaccines are unsafe (often maintaining that vaccine components such as formaldehyde or thimerosal are highly toxic) or alternately argue that governments simply do not have the moral authority to encroach on an individual’s freedom to make medical decisions for themselves or for their children.

Introduction: The incidence of STI-HIV/AIDS is on the rise, making adolescents a vulnerable group at risk. Objective: To increase the knowledge and perception of risk about STI-HIV/AIDS, through Educational Intervention in students of the Polytechnic Institute ¨Hermanos Gómez¨ of the Municipality San José de las Lajas, Mayabeque Province. Method: Quasi-experimental study, intervention at the ¨Hermanos Gómez Polytechnic Institute, of the Municipality of San José de la Lajas, through affective, participatory, animation and reflection techniques, the universe being made up of 17 students aged 16-17 years of specialty in Industrial Chemistry, during the period from December 2014 to November 2015. The variables used were: knowledge about STI-HIV/AIDS and perception of risk towards said diseases. Results: after the intervention, an increase in the level of knowledge of the main STIs in the study was evident: Syphilis, Condylomas, HIV/AIDS, Gonorrhea, Trichomonas, Candida Albicans and Herpes simplex, which were adequately identified by 60%; 71% recognized the routes of sexual transmission, 60% the typical clinical manifestations, an increase in the levels of knowledge about the use of condoms to prevent STIs, and in the same way the perception of risk in an 83% after the intervention. Conclusion: After the intervention, there was an increase in knowledge of STIs, transmission routes, clinical manifestations, condom use, and risk perception.

Zinc induced pediatric preventing respiratory 2019-nCoV is required that supplementation with zinc gluconate 20 mg in Zn deficient children resulted in a nearly twofold reduction of acute lower respiratory infections as well as the time to recovery. Zinc supplementation in children is associated with a reduction in the incidence and prevalence of pneumonia. Preventing 2019-nCoV pneumonia is required that zinc supplementation alone (10 to 20 mg) for more than 3 months significantly reduces in the rate of pneumonia. zinc pediatric intake may be required to be effective range 10～20 mg/d for 2019-CoV prevention, 10～30 mg/d for reduction of COVID-19 bronchitis, and 20～30 mg/d for recovery from COVID-19 pneumonia, in which Zn2+ could bind with viral surface proteins by Zn2+ions-centered tetrahedrally coordination pattern. On the other hand, for aults, the zinc-homeostatic immune concentration may provide a protective role against the COVID-19 pandemic, likely by improving the host’s resistance against viral infection. 50 mg of zinc per day might provide an additional shield against the COVID-19 pandemic, possibly by increasing the host resistance to viral infection to minimize the burden of the disease. In order to prevent that an outbreak of respiratory sickness caused by a novel coronavirus (COVID-19) has become a serious public threat and disrupted many lives,assessing the efficacy of FDA-approved Zn-ejector drugs such as disulfiram combined with interferon to treat COVID-19 infected patients has been proposed. The key strategies for preventing lung damages include avoiding direct lung infection, altering host-virus interactions, promoting immune responses, diluting virus concentrations in lung tissues by promoting viral migration to the rest of the body, maintaining waste removal balance, protecting heart function and renal function, avoiding other infections, reducing allergic reactions and anti-inflammatory. The interactions had been found on the binding specificity by Zn2+ ions-centered tetrahedral geometric coordination of the inhibitors against 3C and 3C-like proteases. In addition, transient zinc chelation TPEN and EPDTC have been noted as preventing virus replication. Zinc-induced ROS production in COVID-19 respiratory ailment and pneumonia occurs both in children and adults. In children. ROS production in zinc (Ⅱ)-immune pediatric patient with COVID-19 bronchitis and pneumonia cannot be elucidated yet. In adults, zinc induced ROS generation in pulmonary COVID-19 infected cells is that alterations of ROS-producing and scavenging pathways that are caused by respiratory viral infections are implicated in inflammation, lung epithelial disruption, and tissue damage, and, in some cases, even pulmonary fibrosis. The involvement of oxidative stress in cell deaths caused during RNA virus infection and ROS production is correlated with host cell death.

Bee venom is a very rich and varied biochemical complex, which explains the multitude of its physiological effects as well as its medical indications. In dermatology, apart from psoriasis, few studies have been conducted concerning its interest and effectiveness; however the preliminary results remain so promising and encouraging. We present a clinical case illustrating the efficacy of bee venom in cutaneous varicosities, with a review of the literature of its main dermatological indications.

Preface Lipoma arborescens is an exceptional condition comprised of frond-like excrescences of mature adipose tissue. The condition was originally described by Albert Hoffa in 1904 with characteristic morphology of macroscopic, villous, frond- like excrescences recapitulating a tree-like appearance, as denominated by the term “arborescens” [1]. Lipoma arborescens is additionally designated as “diffuse articular lipomatosis”, “villous lipomatous proliferation of synovial membrane” or “diffuse lipoma of joint”. The essentially benign condition appears within large joints and typically exhibits adipose tissue infiltration of sub-synovial connective tissue. Synovial sheaths of tendons are infrequently incriminated [1,2].

Related COVID vaccine production many different strategies was followed by the producers. Observing some rare event of thrombosis after some COVID-19 vaccination, it is interesting to verify if the Target used for the manufacturing can be involved in a different procoagulant activity or not. Some vaccine are suspended in some country or under a deep new verify- investigation by the regulatory agency. (EU or USA). This fact it is relevant. The target SPIKE-PROTEIN FULL LENGTH modified or not or towards the RBD domain can be a relevant factor.

Ranitidine is a widely used drug in Europe and its intake is usually well tolerated. Hypersensitivity reactions due to ranitidine are uncommon. The immediate mild reactions type are the most prevalent. In some special cases a delayed type reaction such as contact dermatitis or severe reactions with systemic involvement have been reported. In the present paper, a case report of a 78-year old patient who experienced a maculopapular eruption after 7 days of oral treatment with ranitidine is described. Patch tests were performed twice with ranitidine with positive results confirming the diagnosis. In order to discard a double sensitization and a possible cross-reactivity phenomenon, patch test was performed once with famotidine, with a negative result. This is the first maculopapular exanthema reported as type IV hypersensitivity reaction to ranitidine confirmed by patch testing. Moreover, there are only two reported cases showing a double sensitization to ranitidine and to other H2-receptor antagonists by patch testing after a delayed reaction due to ranitidine, the other being H2-receptor antagonists involving cimetidine and nizatidine, not famotidine.

Amyloidoma is an exceptional, progressive disorder demonstrating a characteristic accumulation of significant quantities of amyloid within soft tissues. Amyloidoma is additionally nomenclated as tumoural amyloidosis, nodular amyloid or localized amyloidosis. Furthermore, insulin-derived amyloidoma is referred to as insulin ball. Amyloid is a protein polymer configured of identical monomeric protein units wherein pathological variety is articulated from misfolded proteins. In excess > of twenty three subtypes of proteins can configure amyloid fibres in vivo. Extra-cellular or intra-cellular deposition of amyloid can modify normal organ function [1]. Amyloidosis is categorized into systemic and localized subtypes. Localized amyloidosis displays a localized mass effect and demonstrates a superior prognosis. Insulin-derived amyloidosis was initially documented by Storkel, et al. in 1983 who recognized accumulated insulin- amyloid fibrils in diabetic individuals subjected to continuous infusion of porcine insulin over a period of 5 weeks or more [1,2]. Amyloid nodules may be associated with systemic amyloidosis.

Introduction: Endothelial progenitor cells (EPC) are involved in vascular repair and proliferation, contributing to the long-term outcomes of apheretic treatment. Aim of this study was to investigate the relationships between endothelial function, assessed by levels of bone marrow-derived progenitor cells and endothelial response to hyperaemia, and clinical and biohumoral parameters in high vascular risk patients before, immediately after, 24-hours and 72 hours after a single lipid apheresis procedure. Material and Methods: We evaluated lipid profile, endothelial function and endothelial progenitor cells before (T0), immediately after (T1), 24h after (T2) and 72h after (T3) a lipoprotein apheresis procedure, in 8 consecutive patients [Sex: 62.5% M; Age; 63.29(12), mean, (range) years] with a personal history of acute coronary syndrome, symptomatic peripheral arterial disease and elevated plasma levels of lipoprotein (a) [Lp(a)]. Patients were on regularly weekly or biweekly lipoprotein apheresis, and they were treated with the FDA-approved Heparin-induced Extracorporeal LDL Precipitation (H.E.L.P.) (Plasmat Futura, B.Braun, Melsungen, Germany) technique. PAT values were expressed as the natural logarithm (Ln-RHI, normal values≥0.4) of the reactive hyperaemia index (RHI), which is the parameter automatically calculated by the device. Results: We found a reduction in the natural logarithm of reactive hyperaemia index (Ln-RHI), assessed immediately after the procedure (0.57±0.21 vs 0.72± 0.29); difference between T2 and T0 was statistically significant (0.43±0.24 vs 0.72±0.29; p=0.006). Reduction in Ln-RHI values was documented in all patients, two subjects showing a Ln-RHI<0.4 at T1, and four at T2. At T3, PAT values were increased significantly (0.91±0.18) in comparison to T1 and T2, showing a median value higher than at T0. Cd34+/Kdr+ and Cd133+/Kdr+ showed a minimum increase in median values at T1, and a higher increase at T2, in comparison to baseline. Differences in Cd34+/133+/Kdr+ values at different times were not statistically significant. A significant reduction in circulating endothelial cells (CEC) count at T2 in comparison to T0 was found (12.00±8.85 vs 23.86±12.39; p=0.024). Discussion: At 24h and 72h after procedures, we found an improvement in endothelial function, expressed by an increase in PAT values and EPC levels, and by a reduction in CEC.

When grouping children with psoriasis depending on TaqI (T/C) genotypes of the VDR gene, the youngest age of disease onset and the longest duration of dermatitis (5.60 ± 0.77 years and 4.90 ± 0.68 years, respectively) showed up in case of the CC genotype. In case of the TT genotype, disease onset coincided with an older age, and the history of present illness was the shortest (10.26 ± 0.64 years and 2.59 ± 0.58 years, respectively). PASI (20.32 ± 3.43) and BSA (40.00 ± 6.11) severity indices were the highest and of statistically significant difference to those in other groups in the presence of the CC genotype. In case of the TC genotype, the index PGA (2.80 ± 0.15) was the lowest and made a statistically significant difference to the values of other groups. A negative correlation between vitamin D levels and the PASI, PGA, BSA was identified in children holding CC and TC genotypes. Conclusion: The clinical presentation of dermatitis and its epidemiological features in children with psoriasis, namely the age of disease onset, duration of exacerbation, body surface area and the intensity of psoriasis symptoms depend on vitamin D serum levels and genotypes of the TaqI polymorphic variant of the VDR gene.

Background: Popliteal artery aneurysms (PAAs) are rare, but the diagnosis should not be missed because of the limb and life threatening complications. The purpose of this study was to reach a consensus about the management of PAA based on our own experience and the available literature. Materials and Methods: This is a retrospective analysis of all patients who underwent an open surgical PAA repair at our institution from January 2015 to December 2016. Demographic data, risk factors, clinical presentation, aneurysm characteristics, type of repair and results were reviewed. Results include patency and major complications. Results: Seven patients underwent an open surgical PAA repair (six men). Median age was 72 years. A posterior approach (PA) was chosen four times and a medial approach (MA) was chosen three times. We performed six resections with interposition of a graft and only one ligation with a bypass. Five patients recovered well, did not develop any complication and did not need a second intervention to guarantee patency. These patients underwent a resection of the aneurysm and interposition of a graft (four via a PA and one via a MA). One patient treated by resection and interposition of a Dacron graft via a MA underwent an above-the-knee amputation at postoperative day 14. This patient had a preoperatively dysfunctional leg since several months with no patent outflow vessels. Our patient treated by ligation and bypass via a MA, developed an acute ischemia four months postoperatively because of an extreme flexion of the knee during several hours while watching TV. After unsuccessful trombolysis, he underwent a femorotibial bypass and a partial forefoot amputation. No long-term results are yet available. Conclusions: In our opinion, open surgical repair of PAAs by resection of the aneurysm and interposition of a venous graft has the best results. Depending on the relation to the knee joint and thus the accessibility of the aneurysm, a posterior approach is preferred. We are not convinced of endovascular techniques in the treatment of popliteal artery aneurysms

Ruptured abdominal aortic aneurysm (rAAA) carries high morbidity and mortality. Advances in endovascular techniques in the last two decades allow for minimally invasive approach for repair of these aneurysms. A succinct but comprehensive pre-operative is essential for delivery of a safe anesthetic for the patient with rAAA. Placement of proximal occlusion balloon in the descending aorta using the rapid control technique can be life-saving. Endovascular aortic repair (EVAR) can be performed under monitored anesthesia care using local anesthetic and IV sedation, and with fewer invasive lines. However, rapid conversion to general endotracheal anesthesia should be expected. Anesthesiologists should be familiar with the hemodynamic management of rAAA and be ready to provide resuscitation to correct for anemia, coagulopathy, and acidemia. In addition, the anesthesiologist should be aware of the common complications related to EVAR, including abdominal compartment syndrome, distal ischemia, and local vessel injury.

The administration of a drug substance is an essential step in the management of a patient. It aims either to cure the patient, to prevent a given disease or sometimes to help with the diagnosis. Unfortunately, the action of the drug can go beyond the desired effect, and cause skin-mucous accidents. These accidents, also known as drug-induced attacks, can be isolated or associated with systemic manifestations [1]. Drug eruption is a real public health issue because of the high frequency. In Europe, drug eruption is responsible for about 20% of spontaneous reports of drug accidents. They complicate 2% to 3% of hospital treatments and motivate 1% of consultations, 5% of hospitalizations in dermatology [2]. Some African authors were interested in the subject. Reported prevalence in hospital settings ranges from 0.4% to 1.53% [3,4]. In Mali, there are no national figures. Old statistics from the Department of Dermatology show that about thirty cases occur each year, most of which are represented by severe forms. However, the risk of drug eruption is thought to be very high due to increased local use of drugs without medical advice, the illegal proliferation of drug outlets (‘Street Medicine’). And the lack of enforcement of existing regulations. In addition, some authors believe that the advent of antiretrovirals and the use of antiInfectious infections used to treat opportunistic infections have increased the risk of Drug eruption by 4 to 30 times, particularly in subjects infected with the acquired human immunodeficiency virus (HIV) [2]. This same risk can be observed in leprosy patients on combination chimotherapy. Clinically, the diagnosis of drug eruption is not as easy as one might think because of clinical polymorphism. The responsibility of a drug for the onset of a reaction is also not easy to establish, as in most cases several drugs are administered simultaneously before the onset of the rash. Because of illiteracy, patients find it difficult to make a complete list of the molecules consumed. To this must be added the high frequency of counterfeit medicines circulating both on the street and in private pharmacies. Given the scarcity of African studies and due to local specificities, it seemed interesting to us to undertake a study on Drug eruption in the dermatology department of the Dermatology teaching hospital of Bamako whose purpose is to study epidemiological aspects, clinical, etiological and to identify the molecules responsible in these patients.

According to recent guidelines, endovascular angioplasty is the standard treatment for TASC A and B primary aorto-iliac occlusive (AIOD) disease, and the first-line approach for TASC C lesions [1,2]. Extended TASC D occlusive disease is usually treated by open surgery yielding excellent patency rates at a cost of a higher mortality (2%-4%) and a severe morbidity (up to 10%) [3]. However, several studies have reported promising results after endovascular treatment of extensive AIOD and full reconstruction of the aortic bifurcation [4,5]. In a recent meta-analysis, Jongkind et al., concluded that endovascular treatment of extensive AIOD can be performed successfully by experienced interventionists in selected patients [6]. Although primary patency rates seem to be lower than those reported for surgical revascularization, reinterventions can often be performed percutaneously yielding a secondary patency comparable to surgical repair.

Delivering health care is a complex task that marginalized a portion of the population intentionally or unintentionally. Discrepancy in health care providing to the intended patients is sometimes accompanied by unintended collateral damage to the bystanders who desperately needing our help and assistance.

Background: Congenital Vascular malformation relatively rare and extremely varied clinical presentations. The purpose of our study was to present our initial experience of embolization in a series of 26 patients with congenital vascular malformation to assess retrospectively the results and the complications of ethanol and coils embolization treatment of these patients. Methods: Retrospective trial, the study group consisted of 26 patients with congenital vascular malformations. Transcatheter arterial embolization by ethanol or coils were performed, Therapeutic outcomes were established by evaluating the clinical outcome of symptoms and signs, as well as the degree of devascularization at follow-up angiography. Results: Between November 2014 and March 2018, 26 consecutive patients (3 male, 23 female) at Alshifa Hospital - Cardiac Catheterization Center with congenital vascular malformations in the body and extremities underwent staged ethanol or coils embolization. The mean age of the patients was 25 years (age range, 6– 59 years). Ethanol embolization was administrated in 16 patients, coil embolization in 9 patients and graft stent in one patient. The side effect such as pain, pulsation, and bruit in most of the patients were obtained. The reduction of redness, swelling, and warmth was achieved in all of the patients, According to the angiographic findings, congenital vascular malformation were devascularized 100% in 12 patients, 50% to 99% in 11 patients, less than 50% in 3 patients. The most common complications were reversible skin necrosis. Conclusion: Transcatheter embolization by ethanol or coils has proved efficacious and safe in the treatment of congenital vascular malformation of the body and extremities but with acceptable risk of complications

Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired hematologic condition which could be revealed by deep venous thrombosis. It could be fatal unless correctly treated. Case report: We report here the case of a 28 year-old male with no medical history who was admitted to the emergency room for severe abdominal pain. Computerized Tomography angiography (CT) scan revealed portal vein thrombosis. Laboratory findings showed pancytopenia with severe regenerative normocytic anemia resulting in PNH. Because of the lack of Eculizumab, treatment was first based on curative anticoagulation until bone marrow transplant, with no success. Conclusion: PNH remains a severe disease with bad prognosis unless treated with Eculizumab.

Background: The plant Artemisia annua has been used in traditional Chinese medicine for many years. Rich in bioactive molecules, the A. annua plant is used to extract the anti-malaria compound artemisinin (< 1%), which results in most of the plant being unutilized. One byproduct of artemisinin extraction is artemisia naphtha (AN), which has yet to be studied extensively. Aims: Study the activity of a novel AN oil extract against microbes, pro-inflammatory cytokines, and dermatological endpoints that are key for eczema and acne pathogenesis to determine if an effective A. annua extract for these skin conditions can be developed. Methods: Gas chromatography-mass spectrometry was performed to determine the composition of AN oil. P. acnes, S. aureus, M. furfur, and C. albicans were cultured to determine minimal inhibitory concentration. in vitro studies utilizing keratinocytes and macrophages were treated with AN oil and gene expression measured by quantitative RT-PCR. A 13-subject clinical trial was performed with 1% AN oil Gel to assess its potential benefits for sensitive and acne prone skin. Results: AN oil upregulates filaggrin gene expression and possesses antimicrobial and anti-inflammatory activity inhibiting LPS, S. aureus and "Th2 induced" pro-inflammatory mediator release (IL-6, IL-8 and TSLP). Clinical assessment of 1% AN Gel shows it reduces acne blemishes and the appearance of redness. Conclusion: Previously an underutilized and unpurified byproduct, AN is now the source to develop the first topical AN oil for cosmetic use with an activity profile that suggests it is effective for those with sensitive and/or acne prone skin.

Pulmonary embolism (PE) is an age-related disorder which is potentially fatal, but frequently misdiagnosed. However, the true prevalence of pulmonary embolism is unknown. Inaccurate estimates of PE prevalence might, in part, be attributable to underrecognition of atypical presentations of this disorder. If true prevalence is unknown, the positive predictive values of both typical and atypical symptoms and signs of PE will be unreliable. The negative predictive value of those parameters will, likewise, be unreliable. The aim of this review is to make clinicians more aware of atypical manifestations of PE, thereby increasing the likelihood of correct diagnosis and, hence, ascertainment of the true prevalence of PE. The range of atypical manifestations was explored by a literature search, using MEDLINE from 1946 to February 2019, and EMBASE, from 1947 to February 2019, and Pubmed, from February 2014 to February 2019, using the search terms atypical, uncommon, unusual, pulmonary embolism, lung embolism, pulmonary thromboembolism. This search revealed atypical presenting features such as non pleuritic retrosternal pain, abdominal pain, atypical breathing patterns, pulmonary oedema, Dressler’s syndrome, atypical radiographic manifestations, atypical electrocardiographic features, manifestations associated with oxygen saturation of 95% or more, coexistence of acute myocardial infarction and pulmonary embolism, coexistence of thoracic aortic dissection and pulmonary embolism, neurological manifestations other than stroke, paradoxical embolism, acute venous thrombosis of atypical location, and pulmonary embolism with normal D-dimer levels.
