  • Prevalence, clinical characteristics and related mortality of cirrhosis in a tertiary hospital setting in Sub Saharan Africa

    Background: Published data on the prevalence and mortality associated to cirrhosis is rare in Cameroon. The aim of this study was to determine the prevalence, clinical and para clinical characteristics and associated mortality of cirrhosis at the Yaounde University Teaching Hospital (YUTH), Cameroon. Methods: Files of patient’s followed up or admitted for cirrhosis at the YUTH between June 1st 2016 and June 30th 2018 were reviewed. The diagnosis of cirrhosis was made based on clinical, biological, ultrasonographic and/or endoscopic signs of portal hypertension and chronic liver failure. In other to establish the cause of cirrhosis, markers of documented chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) was sought in the file of the patients and if not present, hepatitis C antibody and hepatitis B surface antigen testing were requested. In patients negative for HBV and HCV markers, alcohol intake was considered as a cause of cirrhosis in someone who have been consuming more than 30 g/day (for males) or more than 20 g/day (for females) of alcohol. Data analyses were performed using Epi info V 3.5.4. Results: During the period of study, 1748 patients were admitted in the internal medicine unit among which 117 had cirrhosis giving a prevalence of 6.7%. There were 67 males (57.3%) and 50 females (42.7%). The mean age of patients was 51 +/- 19.862 years. Patients with HCV related cirrhosis were older (mean age: 68years) than those with HBV induced cirrhosis (mean age: 38years). The most frequent signs were ascites 104 patients (88.9%), asthenia 92(78.6%), hepatomegaly 68(58.1%), jaundice 61(52.1%), abdominal distension 54(46.2%) and gastrointestinal bleeding 29(24.8%). Anaemia was present in 58 patients (49.6%), thrombocytopenia in 56 patients (47.9%), low prothrombine time in 64 patients (54.7%). Mean serum albumine was 27.59 g/l (6-70), mean total bilirubine 49.41mg/l (3-275mg/l), mean AFP 75693 mg/ml (0.8-1578022). Spontaneous…

  • The Effect of Plain Cigarette Packaging on Implicit Attitudes

    Rationale: The significance of this research stems from the impact implicit attitudes have on smoking behavior, where positive implicit attitudes can result in a greater likelihood of smoking behavior. Even though it has previously been argued that implicit attitudes can drive addictive behavior there is a lack of research on whether cigarette packaging has an influence on implicit attitudes. Objectives: The purpose of this study was to examine the effect of plain cigarette packaging and designed/logo cigarette packaging on implicit attitudes. Methods: Implicit attitudes towards cigarette packaging were assessed by means of the Brief Implicit Association Test (BIAT). A questionnaire was conducted to assess sociodemographic and smoking behavior. The Fagerström Test for Nicotine Dependence (FTND) was used to assess level of dependence. The sample consisted of 264 participants. Results: BIAT indicate a significant association between designed/logo cigarette packaging and positive implicit attitudes (Mean d-score > .15). Cigarette packaging design’s influence on implicit attitudes is positive (Mean d-score = .22), where there is a slight association between designed/logo packaging and positive implicit attitudes. Conclusions: When compared with plain packaging, designed/logo cigarette packaging leads to positive implicit attitudes. These findings support the effectiveness of plain packaging regulations where the removal of color, design and logo from cigarette packaging will decrease positive implicit attitudes formed by cigarette packaging.

  • Usefulness of Castor Oil and Elobixibat and Lactulose and ascorbic Aid for Bowel Preparation for Colon Capsule Endoscopy-Initial examination

    Colon capsule endoscopy was approved for reimbursement under the national health insurance system of Japan in 2014. However, the capsule excretion rate after recommended bowel preparation reportedly ranges from 70% to 90%, and administration of boosters is also necessary. The caster oil-based booster had an emission rate of 97%, but required a total water content of 3L. Considering whether it is possible to popularize colon capsule endoscopy by reducing the amount of water, including dialysis patients with water restrictions, we will consider whether the capsule discharge rate can be improved by combining new laxatives.


    Objectives: Metastatic tumors to the oral cavity are observed extremely rarely, accounting for approximately 1% of all malignant oral lesions. The purpose of our study is to record and analyze the data of the patients who revealed metastasis to the oral cavity. Material and Methods: The records of the patients diagnosed with oral metastases who were admitted to Oral and Maxillofacial Surgery Departments from 1996 to 2018 were reviewed and analyzed for demographic data and outcomes. Results: Over a period of 22 years (from 1996 to 2018), 22 patients were admitted to the Oral and Maxillofacial Surgery Departments of General Hospital G. Papanikolaou and Theageneion Anticancer Hospital with oral metastasic tumors from a distant primary site. Conclusions: Metastasis to the oral cavity is a very rare finding but it exists so we have to be aware of it and have in mind the possibility of this condition.


    Background: Axillary hyperpigmentation is a common and troublesome complaint especially among dark-skinned women. It is believed to be a form of post-inflammatory hyperpigmentation and so far, there is no universally accepted treatment for the disorder. Objective: The aim of this study is to assess the efficacy of fractional CO2 laser in the treatment of axillary hyperpigmentation Patients and methods: Thirty Egyptian females with axillary hyperpigmentation were recruited. The severity of the condition was estimated by both self-assessment and expert dermatologist before treatment. Four sessions of fractional CO2 laser were done. Both the efficacy and complications were assessed by the patient and the dermatologist six month after the last session. Results: There was a statistically significant difference of percentage of improvement of pigmentation before compared to one month after treatment as detected by self-assessment (p value= 0.002) and the observer’s assessment (p value= 0.001). Conclusion: Fractional CO2 laser, in properly chosen parameters, is an effective method for the treatment of axillary hyperpigmentation.


    Background: Treatment of resistant alopecia totalis AT is a major problem in general practice. Some studies reported the use of either excimer-308 or intra-muscular triamcinolone acetonide as a monotherapy, with conflicting results. Objective: To evaluate the therapeutic effect of combining 308-excimer phototherapy and intramuscular triamcinolone acetonide for the treatment of alopecia totalis. Methods and Material: Ten patients with alopecia totalis were evaluated in this prospective interventional study. All patients were assigned to receive the thera-peutic regimen that includes monthly IM triamcinolone acetonide (TAC) for a maximum of six pulses and twice-weekly excimer phototherapy for 24 sessions. Results: The overall response rate for this regimen was 90%, with four patients 40% achieving complete regrowth of hair (100%). Three patients have exhibited a satisfactory response (>70% regrowth). Unsatisfactory response ( >10-< 70% regrowth) was reported in two patients . Younger patients responded better, as did those with a shorter history of the disease P < 0.05. At follow-up, which continued for 8–12 months, recurrence was noted in two (22.2%) of the nine responders. Conclusions: Combining excimer phototherapy with triamcinolone acetonide showed a promising effect on resistant AT. This treatment modality was effective and well tolerated particularly in young patients.


    Background: Most previous research has focused on acne vulgaris characteristics and their association with psychological disorders, such as anxiety and depression. Objective: In the present study, we aimed to show whether acne characteristics are associated with several aspects of psychological well-being namely self-esteem, body satisfaction, anxiety-depression and dermatological life quality. Methods: This was a study of 200 patient with acne and190 healthy controls that was carried out in Antalya, Turkey. Main outcome measures were the Rosenberg’s Self-Esteem Scale, Body Image Concern Inventory (BICI), hospital anxiety and depression scale (HAD) and dermatological life quality index (DLQI). Also we recorded global acne grading score (GAGS) of acne patients. Results: The findings of statistical analysis indicated that patients with acne had lower levels of self-esteem, high depression and HAD score compared with healthy controls (respectively p=0.01, p˂0.01, p=0.01). Also the DLQI scores of severe and very severe group had higher than mild and moderate group (p= 0.013) Conclusion: The emotional well-being of the patients presenting with the acne needs to be recognized more fully, particularly in relation to the low self-esteem, high depression score. The psychosocial impact of acne vulgaris should be valued in the management of patients with this condition. The results of this study raise implications for clinical practice and suggest that a multidisciplinary approach to the management of patient with acne.

  • Prevalence and Perceptions of Cigarettes, Vaping, and Waterpipe Among Veterans

    Introduction: Vaping has become an epidemic with serious health concerns. The Centers for Disease Control and Prevention recently released a national alert on vaping hazards and its associations with a mysterious lung disease. The prevalence of alternative tobacco products such as waterpipe and vaping have been on the rise, with health hazards similar to those of cigarettes. However, the public is less aware of those hazards. Because the literature on alternative tobacco use among Veterans is limited, the purpose of this study is to examine veterans’ use, perceptions, and knowledge of the hazards linked to alternative tobacco products. Materials and Methods: A convenience sample of 200 veterans seeking medical care at the Rocky Mountain Regional VA Medical Center, primary care clinics completed a survey on tobacco use. Results: Cigarettes remain the most prevalent form of tobacco used by veterans. The prevalence of “ever use” of waterpipe and/or vaping was 21% among participants, and almost all of those participants also reported cigarette use, 20.5%. About 42% of participants were unaware of harm levels from waterpipe. Discussion: Veterans are unaware of the risks associated with vaping and other alternative tobacco products and show similar use rates as the general population. Because educational campaigns have proven to be successful in decreasing smoking, the next step is to conduct educational campaigns on the hazards of alternative tobacco products among the veteran population to address myths and misperceptions regarding those products.

  • A study on green cosmetic brand equity and purchase intentions

    The concept of sustainable development has recently become a significant issue among industrial, academic, and government sectors. As consumers have more green awareness of products, the markets of natural and organic products set to be flourish, the organic certification approach is then expected to be a crucial role between consumers and green brands. For the green cosmetic brands, it might bring more benefits to the brand than just being a proof of organic ingredients. The study conducted a quantitative questionnaire survey which was developed for this study and based on the four components of brand equity: brand associations, brand loyalty, perceived quality and brand awareness. Taking COSMOS-standard as an example, the study explores the influence it might have on green cosmetic brand equity and purchase intentions. Using snowball sampling for data collection, the total number of respondents was 867 and the number of valid questionnaires was 623. The statistical software SPSS 22.0 was used for the analysis. The results indicate that COSMOS-Standard organic certification has positive impacts on brand equity and purchase intention; significant differences on brand association and brand loyalty are caused by different disposable income; the effects on improving purchase intention works better on toiletries than facial care products. The cosmetic brands can see the results as suggestions on brand management and marketing strategies.


    Angiokeratomas (AK) are probably the vascular lesions that induce more confusion in the literature. The most accepted classification of AK was performed by Imperial and Helwig , and they divide these lesions into five classical types: Mibelli’s AK, Fordyce’s AK, corporis diffusum AK, circumscribed naeviforme AK and solitary or multiple acquired angiokeratomas. Nevertheless, in the clinical practice, is not unusual to see AK type lesions associated to different types of vascular anomalies, and these lesions have difficult handling. In ISSVA classification AKs have been included as vascular anomalies provisionally unclassified. We perform the differential diagnoses of AKs and according to clinical picture, histopathological aspect, immunohistochemical markers and radiological findings proposed to divide AKs mainly in two groups. Primary AKs are the classical types. The new immunohistochemical findings suggest that these lesions might be included as mixed capillary-lymphatic malformations. Secondary AKs are related with different vascular anomalies, secondary to other process with lymphatic obstruction, related to drugs, or associated with no vascular lesions as lymphoid lesions. Different underlying vascular anomelies might be related with AKs including deep capillary-lymphatic malformations (CLM), venous-lymphatic malformations (VLM), capillary-lymphatic-venous malformations (CLVM) (Klippel-Trenaunauy Sd), deep lymphatic malformations (LM), venous malformations (VM) as hyperkeratotic venous malformation, cavenomatous cerebral malformations, traumatic arteriovenous fistula and eccrine angiokeratomatous hamartoma. Clinical aspect, radiological studies and histopathological examination might help to do a correct diagnosis of this heterogenous entity.
