Primary Cutaneous Low Grade Mucinous Adenocarcinoma of Eyelid
No full textPrimary cutaneous mucinous adenocarcinoma is a rare adnexal neoplasm, eyelid being the most common site of presentation. Clinically it is mistaken for a benign / cystic lesion. Its morphologic similarity to metastatic deposits from breast, gastrointestinal tract (GIT) or any visceral sites adds to the diagnostic difficulty mandating the role of ancillary techniques in precise diagnosis and hence planning the management. We report a case of primary cutaneous mucinous adenocarcinoma of eyelid with emphasis on pathology along with a brief review of literature
Le plan dialectique : pour une alternative au paradigme
No full textIn this paper, I apply the theory developed in "Matrices of concepts" (2002) to the methodology for conceiving a plan. Regarding the dialectical plan, the paradigm is a plan whose structure is thesis-antithesis-synthesis. I describe a new type of matricial dialectical plan, which presents several advantages with regard to the classical dialectical plan and proposes to constitute an alternative to the latter
Closing and Closure in Human-Companion Interactions: Analyzing Video Data from a Field Study
No full textA field study with a simple robotic companion is being undertaken in three iterations in the framework of a EU FP7 research project. The interest of this study lies in its design: the robotic interface setup is installed in the subjects' homes and video data are collected during ten days. This gives the rare opportunity to study the development of human-robot relationships over time, and the integration of companion technologies into everyday life. This paper outlines the qualitative inductive approach to data analysis, and discusses selected results. The focus here is on the interactional mechanisms of bringing conversations to an end. The paper distinguishes between "closing" as the conversational mechanism for doing this, and "closure" as the social norm that motivates it. We argue that this distinction is relevant for interaction designers insofar as they have to be aware of the compelling social norms that are invoked by a companion's conversational behaviour
Effect of Training on Physiological and Biochemical Variables of Soccer Players of Different Age Groups
No full textPurpose: To find out the effect of training on selected physiological and biochemical variables of Indian soccer players of different age groups.\ud
\ud
Methods: A total of 120 soccer players volunteered for the study, were divided (n=30) into 4 groups: (i) under 16 years (U16), (ii) under 19 years (U19), (iii) under 23 years (U23), (iv) senior (SR). The training sessions were divided into 2 phases (a) Preparatory Phase (PP, 8 weeks) and (b) Competitive Phase (CP, 4 weeks). The training program consisted of aerobic, anaerobic and skill development, and were completed 4 hrs/day; 5 days/week. Selected physiological and biochemical variables were measured at zero level (baseline data, BD) and at the end of PP and CP.\ud
\ud
Results: A significant increase (P<0.05) in lean body mass (LBM), VO2max, anaerobic power, grip and back strength, urea, uric acid and high density lipoprotein cholesterol (HDL-C); and a significant decrease (P<0.05) in body fat, hemoglobin (Hb), total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) were detected in some groups in PP and CP phases of the training when compare to BD. However, no significant change was found in body mass and maximal heart rate of the players after the training program.\ud
\ud
Conclusion: This study would provide useful information for training and selection of soccer players of different age groups.\u
The Impact of Immunization Control Activities on Measles Outbreaks in Akwa Ibom State, South-South, Nigeria
No full textBackground: The increase of vaccination rates means that fewer children will be vulnerable to vaccine preventable diseases such as measles, which will invariably result in a drop in the infant mortality and morbidity rates. Objective: To assess the impact of the implementation of measles reduction strategies from 2006 to 2008 using the quarterly national program for immunization (NPI) in Akwa Ibom state, Nigeria. Method: Following informed consent, individuals presenting with febrile rash illnesses were routinely bled and tested for measles specific IgM using commercially available ELISA kit-MV-ELISA (Enzygnost; Behring Diagnostics, Marburg, Germany) in accordance with the manufacturer’s instructions. Results: A total of four hundred and four individuals comprising of 216 vaccinated and 188 unvaccinated, presenting with febrile rash illness were screened for measles specific IgM antibodies as indication of active infection between January 2006 and December 2008 out of which 122 (30.2%) had detectable levels of measles antibodies. Among the vaccinated and unvaccinated groups, 32 (14.8%) and 90 (47.9%) respectively were detected with measles IgM antibodies. The highest and lowest antibody levels were detected in 2006 (vaccinated: 54.7%; unvaccinated: 78.4%) and 2008 (vaccinated: 1.2%; unvaccinated: 12%) respectively. The distribution of measles burden by year show an overall decline in prevalence from 70% in 2006, 8.9% in 2007 to 3.7% in 2008. While, children under the age of 5 similarly had a decline in measles incidence of 73.3%, 10.7% and 3.3% respectively. Sex distribution of infection within the 3-year period shows that more females (37.4%) than males (21.2%) expressed measles IgM antibodies, and active infection was detected more in the rural (31.4%) than urban area (27.7%). However, findings indicate a tremendous decline in active infection in the rural areas from 67% in 2006 to 0% in 2008, and in the urban areas from 78% in 2006 to 9.3% in 2008 among both vaccinated and unvaccinated groups. A highly significant reduction in measles infection was observed more among males than females (P=0.009). Infection distribution by location did not show any significant difference (P=0.65) even though more individuals in the rural areas were noted with active infection. Conclusion: The study shows a highly significant reduction in measles burden among vaccinated individuals (P=0.0001) and invariably increases protective coverage of measles vaccination most especially among children under 5 years of age (P=0.0066) in the state. Findings justify effort by government and WHO in carrying immunization campaigns in children, 5-years and below irrespective of vaccination status and experience
Malignant peripheral nerve sheath tumour: A rare tumour of the breast
No full textMalignant peripheral nerve sheath tumour is a rare tumour of the breast and this report highlights the radiological and histological features and the difficulties in making a diagnosis. A high index of suspicion when dealing with a breast lesion that has both cystic and solid components in a background of von Recklingausen’s neurofibromatosis will make the diagnosis easie
Bronchoscopic evaluation and final diagnosis in patients with chronic non productive cough with normal Chest X ray
No full textWhen a proper detailed history, clinical examination, chest X ray and sputum analysis does not yield a definite diagnosis for the cause of chronic cough, bronchoscopy is indicated. We did a descriptive study among 39 patients who underwent bronchoscopic evaluation for chronic cough (more than 4 weeks) with normal chest X ray and without a prior definitive diagnosis. 16 out of 39 patients were diagnosed to have tuberculosis on analysis of the bronchial washings. 6 patients (66.67%) with left upper lobe mucosal inflammation were AFB smear positive. 5 patients ( 31.25 %) with normal bronchoscopy were AFB smear positive.4 out of 5 patients (80 %) with bilateral upper lobe mucosal inflammation were AFB smear positive. Pulmonary tuberculosis can present with chronic non productive cough and normal chest X ray. Bronchoscopy is helpful in establishing the diagnosis. When bronchoscopy shows bilateral or unilateral upper lobe bronchial mucosal inflammation, possibility of tuberculosis is high. Bronchoscopy can be normal in some patients with pulmonary tuberculosis with normal chest x ray and chronic non productive cough. The key message is that early pulmonary tuberculosis can present with chronic non productive cough and normal chest X ray without any other symptoms suggestive of tuberculosis. Bronchoscopy is helpful in establishing the diagnosi
