Echocardiographic and Etiopathogenic Features of Hypertrophic Cardiomyopathy: Casablanca University Hospital Experience

Hypertrophic cardiomyopathy (HCM) is the most common non-ischemic cardiomyopathy with a prevalence of 1:500 in the general population, based on the recognition of the phenotype. HCM is defined by the presence of increased left ventricular (LV) wall thickness that is not solely explained by abnormal loading conditions and the phenotype also includes disorganized myocyte arrangement, fibrosis, small-vessel disease, and abnormalities of the mitral valve apparatus. In particular to this pathology, we have conducted a one-year prospective study to determine clinical, echocardiographic features and etiopathogenic aspects of hypertrophic cardiomyopathy in the Casablanca university hospital. The results concluded that 50% of the causes was due to amyloidosis 35%, sarcomeric HCM and 15% Fabry disease in which 2 cases were related with pregnancy. Transthoracic echocardiography and cardia MRI plays an important role in HCM diagnosis and prognosis.

Takayasu's Arteritis with Aortic Insufficiency as Initial Presentation: A Case Report

Takayasu's disease is the first cause of inflammatory aortitis in young subjects. The disease preferentially affects the women. Takayasu's disease could be a mode of non-specific reaction of the aorta to various infectious or dysimmune etiological factors. Aortic insufficiency is present in 7 to 10% of cases. It is usually moderate. Its mechanism is not unambiguous: direct damage to the aortic valves or dilation of the aortic annulus. Coronary damage responsible for angina or even myocardial infarction are also possible. We report the case of a severe aortic insufficiency secondary to takayasu disease complicated by acute coronary syndrome in a 42-year-old woman.

Left Main Total Chronic Occlusion in a Patient with Colorectal Cancer: A Case Report of a Rare and Severe Localization of Coronary Artery Disease

The aim of this case report is to draw attention at the potential severity of presentation of these associated pathologies. Prevention through early screening of colorectal cancer in patients with coronary artery disease and vice versa is the guarantee of a better management of the two pathologies. Cardiovascular disease and cancer are the two leading causes of death worldwide. Emerging evidence suggests associations between cardiovascular disease and several cancers, including colorectal cancer. Many cases have reported severe coronary artery disease (CAD) in association with colorectal cancer including triple vessel disease. To the best of our knowledge this is the first case reporting a total occlusion of the left main coronary artery in such patients. We report the case of a 52 years old woman presented to our cath lab for severe angina (Class III of the Canadian classification) and impairment of left ventricle function. Six months before the patient was diagnosed with a metastatic colorectal cancer. Coronary angiography showed absence of anterograde opacification of the left coronary system. Selective right coronary artery angiography showed a retrograde filling of the left coronary system by collaterals issued from proximal and distal dominant right coronary artery. Several studies have reported the association between colorectal neoplasm and CAD but Isolated left main coronary artery disease is extremely uncommon. Patients with left main coronary artery disease have always a grim prognosis and without prompt revascularization 60% will die after 5 years while survivors live with severe angina; heart failure or both.

A Young Healthy Woman with Supraventricular Tachycardia Reveals an Underlying Left Ventricular Non-compaction Cardiomyopathy: A Rare Case Report

LVNC (left ventricular non-compaction) is a rare congenital cardiomyopathy with a reported incidence of 0.05% in adults. It can occur in isolation or affect both ventricles. It’s characterized by prominent LV trabeculae and deep intertrabecular recesses which are filled with blood from the ventricular cavity without evidence of communication to the epicardial coronary artery system. Frequent premature supra ventricular tachycardia as unique finding in LVNC cardiomyopathy is rare manifestation of this disease. We report a case of a frequent persistent supraventricular tachycardia as first manifestation of a patient with LVNC cardiomyopathy in a young healthy woman who despite radio frequency ablation therapy of the supraventricular tachycardia remains symptomatic. The patient was later placed on medical therapy based on a non-cardio selective beta-blocker with a good clinical outcome without recurrent of supra-ventricular arrythmias.

Identification of locally isolated entomopathogenic Fusarium species from the soil of Changa Manga Forest, Pakistan and evaluation of their larvicidal efficacy against Aedes aegypti / Identificação de espécies de Fusarium entomopatogênicas localmente isoladas do solo da Floresta de Changa Manga, Paquistão e avaliação de sua eficácia larvicida contra Aedes aegypti

Dengue fever vectored by the mosquito Aedes aegypti is one of the most rapidly spreading insect-borne diseases. Current reliance of dengue vector control is mostly on chemical insecticides. Growing insecticide resistance in the primary mosquito vector, Aedes aegypti, limits the effectiveness of vector control through chemical insecticides. These chemical insecticides also have negative environmental impacts on animals, plants and human health. Myco-biocontrol agents are naturally occurring organisms and are found to be less damaging to the environment as compared to chemical insecticides. In the present study, entomopathogenic potential of local strains of fungi isolated from soil was assessed for the control of dengue vector. Local fungal isolates presents better alternative to introducing a foreign biocontrol strain, as they may be better adapted to environmental conditions of the area to survive and may have more entomopathogenic efficacy against target organism. Larvicidal efficacy of Fusarium equiseti and Fusarium proliferatum was evaluated against Aedes aegypti. Local strains of F. equiseti (MK371718) and F. proliferatum (MK371715) were isolated from the soil of Changa Manga Forest, Pakistan by using insect bait method. Larvicidal activity of two Fusarium spp. was tested against forth instar larvae of A. aegypti in the laboratory, using concentrations 105, 106, 107 and 108 conidia /ml. LC50 values for F. equiseti after 24h, 48h, 72h and 96h of exposure were recorded as 3.8x108, 2.9x107, 2.0x107, and 7.1x106 conidia /ml respectively while LC50 values for F. proliferatum were recorded as 1.21x108, 9.6x107, 4.2x107, 2.6x107 conidia /ml respectively after 24h, 48h, 72h and 96h of exposure. The results indicate that among two fungal strains F. equiseti was found to be more effective in terms of its larvicidal activity than F. proliferatum against larvae of A. aegypti.

Acute Aortic Dissection Masquerading a Rare Type of Congenital Bicuspid Aortic : A Case Report

Acute aortic dissection on bicuspid aortic valve (BAV) type 0 is a rare especially in young masculine. Risk factors like smoking and intensive sport activities can hasten their apparition especially in non-diagnosed population. Trans thoracic echocardiography is very important in the diagnosis of BAV whereas Angio CT scan helps to confirm acute aortic dissection. Treatment is based on surgery for type A Stanford classification for acute aortic dissection. We report a rare case of acute aortic dissection masquerading a rare type of BAV, type 0 in a young sportive male with no history of heart disease who presented for the first-time with acute chest pain after lifting a heavy weight metal at the complex sport center. Patient was initially placed on medical treatment before surgery for heart valve and root replacement (Bentall procedure).

Comparison of rapid antigen testing and RT-PCR in the diagnosis of COVID-19 in Kashmir division

Background:Accurate diagnosis and widespread use of diagnostic tests with easy accessis important to contain the spread of SARS-CoV-2. A Real-time reverse transcription polymerase chain reaction (RT-PCR) has high cost and can be performed in special laboratories. There have been several easy to perform rapid antigen detection tests developed and recommended to use at point of care for timely detection of positive patients and their isolation to limit the spread of infection. The aim of the study was to compare the cost effectiveness and the role of RT-PCR and rapid antigen testing in diagnosing different suspects of COVID-19.Methods:In this cross-sectional study the data of all the suspected cases who underwent COVID-19 testing over a period of seven weeks at divisional level was used for analysis.Results:The widespread use of rapid antigen testing makes it more cost effective in detecting COVID-19 cases than the highly sensitive and specific RT-PCR testing. Conclusions:Rapid antigen tests can be used as a screening testing tool in high-risk groups to identify the infected persons quickly and for preventing the transmission of infection particularly in low resource settings.

Factors affecting the chitinase activity of Trichoderma asperellum isolated from agriculture field soils

In the present study, 20 fungal strains were isolated from tomato rhizosphere of Senegal. Of 20 strains, five showedthe chitinolytic activity on chitin agar medium. Of the five strains, NG4 showed the maximum solubilization zone.This strain was identified by preliminary biochemical and 18S rRNA sequencing analysis. Enzyme productionstarted after 3 days of incubation and maximum was observed after 5 days of incubation. Culture filtrate amendedwith 0.1% colloidal chitin was used in the production medium. The optimum conditions for maximum chitinaseactivity are – 6 days of growth and temperature of 30°C at pH 6.0. The chitinase activity was also influenced by theaddition of carbon and nitrogen sources in the production medium.

Meal Patterns of Malaysian Adults: Findings from the Malaysian Adults Nutrition Survey (MANS)

Introduction: Meal patterns have received little attention in nutrition studies. The aim of this study is to present the findings on general meal patterns of Malaysian adults. Methods: The Malaysian Adults Nutrition Survey (MANS), carried out in 2002 and 2003, involved 6,928 adults selected by stratified random sampling from all households by zone in Peninsular Malaysia, Sabah and Sarawak. Results: In general, the results showed that most respondents (74.16%) ate three meals per day; 89.20% of the respondents consumed breakfast, while 88.57% consumed lunch and 91.97% consumed dinner with no significant difference in terms of sex. In Peninsular Malaysia, the Northern Zone had the highest number of people consuming breakfast compared to other zones. Meanwhile, the population in Sarawak had the largest proportion of people consuming lunch and dinner, but the smallest proportion of people consuming breakfast. A significantly higher number of the rural population consumed breakfast and lunch than urbanites; however there was no significant difference in dinner consumption. Generally, breakfast consumption increased with age whereby significant difference existed between the 18 to 19 years age group and the age group of 30 years and older. Lunch intake among the age groups showed no significant difference. In contrast, dinner consumption was significantly lower among the 18 to 19 years age group compared to all other age groups. Comparison among the ethnic groups showed that the Indian population had the lowest percentage of having breakfast and lunch while the Orang Asli had the lowest percentage of consuming dinner. However, the Orang Asli recorded the highest percentage for taking breakfast and lunch while the Chinese had the highest percentage of taking dinner. Conclusion: Considering that Malaysian adults consumed their conventional breakfast, lunch and dinner, these findings indicatethat Malaysians are maintaining their traditional meal patterns.

Physical Activity Pattern and Energy Expenditure of Malaysian Adults: Findings from the Malaysian Adult Nutrition Survey (MANS)

This paper aims to report the physical activity pattern and energy expenditure of adults aged 18 – 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October 2002 and December 2003. The survey included 7349 adults representative of Peninsular Malaysia (Northern, Southern, Central and East Coast), as well as Sabah and Sarawak. A total of 6926 adults, comprising 3343 men and 3583 women, completed the physical activity section of the survey. Physical activity data was obtained using a physical activity questionnaire and 24-hour physical activity recall. Basal metabolic rate (BMR) was calculated from Ismail et al. (1998) predictive equations; total energy expenditure (TEE) was then estimated through factorial calculations based on time allocated and energy cost of various activities. Physical activity level (PAL) was calculated as the ratio of TEE to BMR. It was found that almost three-quarters of Malaysian adults travelled by passive modes of transportation. Only a third reported having ever-exercised, and an even smaller proportion of the population (14%) had adequate exercise. The population also spent the majority of their time (74% of the day) in sedentary activities, such as sleeping or lying down; doing light intensity activities (15% of the day), and doing moderate to vigorous intensity activities (10% of the day). Mean BMR and TEE was significantly higher amongst men than women, while mean PAL values were similar for men [1.6 (1.6 – 1.7)] and women [1.6 (1.6 – 1.6)]. More men (16%) were categorised as having active PAL compared to women (10%), while more women (43%) were categorised as having sedentary PAL compared to their male counterparts (37%). The present study provides the first in-depth report of the physical activity pattern, and national estimates of energy expenditure and physical activity levels of Malaysian adults, and concluded that Malaysian adults are generally sedentary. It is thus important that physical activity be further promoted and integrated into the lives of the population, preferably through various health promotion efforts as well as through the commitment of the authorities in providing a suitable environment for an active lifestyle.

Body Mass Index (BMI) of Adults: Findings of the Malaysian Adult Nutrition Survey (MANS)

The Malaysian Adults Nutrition Survey (MANS) was carried out between October 2002 and July 2003, involving 6,775 men and 3,441 women aged 18 – 59 years. Anthropometric assessment showed that the overall mean body weight and BMI were 62.65 kg (CI: 62.20, 63.09) and 24.37 kg/m2 (CI: 24.21, 24.53) respectively. Based on the WHO (1998) classification of BMI, 12.15% (CI: 11.26, 13.10) were obese (BMI > 30 kg/m2), and 26.71% (CI: 25.50, 27.96) overweight (BMI > 25 - 29.9 kg/m2). Significantly, more women were obese [14.66% (CI: 13.37, 16.04)] while significantly more men were overweight [28.55% (CI: 26.77, 30.40)]. Ethnicitywise, prevalence of obesity was highest among the Malays [15.28% (CI: 13.91, 16.77)] while overweight was highest for the Indians [31.01% (CI: 26.64, 35.76)]. Both obesity and overweight were highest among those aged 40 - 49 years. Obesity was highest for those whose household income was between RM1,500 - 3,500 while overweight was more prevalent for those whose household income exceeded RM3,500. The prevalence of overweight was highest for those with primary education [31.90% (CI: 29.21, 34.72)]. There was no significant urbanrural differential in both obesity and overweight. The study found 9.02% (CI: 8.82, 10.61) with chronic energy deficiency (CED) (BMI < 18.5 kg/m2). The prevalence of CED was relatively higher in the indigenous population (Orang Asli) [14.53% (CI: 5.14, 34.77)], subjects aged 18-19 years [26.24% (CI: 21.12, 32.09)], and with monthly household income of < RM1,500 [10.85% (CI: 9.63, 12.20)]. The prevalence of CED was not significantly different among the geographical zones and educational levels, and between urban/rural areas and sexes. The results call for priority action to address the serious problem of overweight and obesity among Malaysian adults as it poses a grave burden to the country’s resources and development.

Daily Energy Intake from Meals and Afternoon Snacks: Findings from the Malaysian Adults Nutrition Survey(MANS)

Meal and snack patterns are associated with energy and nutrient intakes and consequently health and nutritional status. The aim of this paper is to describe the percentage of daily energy intake from meals and afternoon snack among Malaysian adults. The study included a representative sample of adults aged 18- 59 years (n=7349) from a nationwide Food Consumption Survey conducted by the Ministry of Health. Information on dietary intake was obtained using a one day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed using Nutritionist ProTM and statistical analysis was carried out using the SPSS 13.0. The median percentage of daily energy intake is reported only for adults consuming meals and afternoon tea and by socio-demographic characteristics as well as body mass index (BMI) status. More than 80% of Malaysian adults consumed morning meals, lunch and dinner and 54% reported having afternoon tea. The median percentage of energy intake from morning meals, lunch, dinner and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were variations in the median percentage of energy from meals and snacks according to the socio-demographic variables and BMI status. It is important to understand the eating patterns of Malaysians as the information can assist in efforts to address obesity and diet-related chronic diseases among adults.

Presenting features in Pakistani patients suffering from the antineutrophil cytoplasmic antibody - classical subtype [c-ANCA] associated vasculitis

To study the clinicopathological features in c-ANCA positive patients suffering from vasculitis with a view to find out the most common mode of presentation. STUDY DESIGN: Retrospective. SETTINGS: Department of Immunology, AFIP, Rawalpindi, MH Rawalpindi, CMH Rawalpindi, Department of Rheumatology, PIMS, Islamabad, RGH Rawalpindi, FFH, Rawalpindi. SUBJECTS: Seventeen patients suffering from vasculitis and found to be positive for c-ANCA. MAIN OUTCOME MEASURES: Clinico-pathological features at presentation. There were 9 males in age range 11-60 years [mean age 32.5 years] and 8 females in age range 26-42 years [mean age 32.3 years]. Common presenting features were a combination of cough, blocked nose and post nasal drip 14/17 [82%] followed by nose bleed and haematuria 11/17 [65%]. Six patients were demonstrated to be suffering from Wegener's granulomatosis after biopsy. C-ANCA was detected by indirect immunofluorescence in the titre range of 8-640. The auto antibody levels related to disease activity. c-ANCA associated vasculitis is a rare [17 patients in five years] but aggressive form of vasculitis. It must be suspected in patients with persistent respiratory tract related symptoms associated with fever and joint pains which fail to respond to adequate treatment for infections. The c-ANCA estimations can be utilised as sensitive and specific diagnostic and prognostic marker in this form of vasculitis

Antibodies to the extractable nuclear antigens [ENA] in Pakistani patients with systemic rheumatic disease

Autoantibodies to the saline extracts of cells are being used as diagnostic and prognostic markers in the investigation of patients with suspected systemic rheumatic disease. These are also called antibodies to the extractable nuclear antigens or anti ENA antibodies. We used saline extracts of human spleen cells and rabbit thymus extract to detect six subtypes of anti ENA antibodies, namely anti SSA [anti Sjogren's syndrome A], anti SSB [anti Sjogren's syndrome B], anti RNP [anti Ribonucleoprotein], anti Sm [anti Smith], anti Jo-1 [anti Jo-1] and anti Sc1 70 [anti Systemic sclerosis 70] antibodies. Two hundred and thirty-seven patients' sera were screened in the department of Immunology, Armed Forces Institute of Pathology [AFIP], Rawalpindi, over a period of 16 months. Fifty-seven were positive for auto antibodies, of which 26 had anti SSA antibodies, 12 anti SSA+ anti RNP+ anti Sm antibodies, 7 anti RNP+ anti Sm antibodies, 6 anti SSA+ anti SSB antibodies, 5 anti SSA+ anti RNP antibodies while one patient showed only anti RNP antibody. The detection of the anti ENA antibodies was specially helpful in diagnosing patients with systemic lupus erythematosis presenting with atypical features and with mixed connective tissue disease
