[Status of health and oral health of the elderly population in Lebanon]. / État des lieux sanitaire et bucco-dentaire de la population gériatrique libanaise.

Lebanon is in demographic transition as more people reach increasingly older age; 10% of the population in Lebanon is elderly. The incidence of chronic diseases and oral diseases increases significantly with age. However, 55% of the elderly have no health insurance and 82% have no dental insurance. Both noncommunicable diseases (NCDs) and oral diseases are a major health burden in the country and share the same risk factors. The WHO strategy for prevention and control of noncommunicable diseases should therefore be a new approach for the prevention and control of dental diseases among Lebanese elderly. This paper aims to increase the awareness of the medical community in Lebanon about the interrelationship between general and oral health in the elderly and concludes with the need for the Ministry of Health to develop policies and national action plans against NCDs to reduce not only mortality from NCDs but also morbidity from oral diseases.

Sentinel lymph node detection by intranipple injection of patent blue dye in breast cancer: a preliminary report of a feasibility study.

Sentinel lymph node (SLN) biopsy is a well established option for assessing axillary lymph node status in breast cancer. Several techniques have been applied so far (superficial or deeper ones). Based on anatomical features of the lymphatic drainage in the breast, we assessed the feasibility of an intranipple approach for SLN mapping. Our data support the feasibility of SLN detection by our technique, with a high rate of SLN identification, which could be used in clinical practice as an alternative to the peri-areolar approach.

[Impact of low socioeconomic status on the demography and co-morbidities of asthma]. / Influence du niveau socioéconomique bas sur la démographie et les comorbidités de l'asthme.

OBJECTIVES: Asthma is a frequent and serious chronic respiratory disease which is sometimes fatal. It involves all ages and all social subclasses. The goal of our study was to determine the demography of asthma in a low socio-economic community in Lebanon and to describe its association with various epidemiologic factors. MATERIALS AND METHODS: The computerized data of 44.814 patients of a nongovernmental organization (Hariri Foundation), in Lebanon were reviewed. Asthmatic patients diagnosed by a health professional on the basis of medical criteria during the period from January 2003 to June 2005 were included in the analysis. The socio-economic characteristics of this population were retrieved and their geographical distributions were depicted. The study focused on the association of asthma with cutaneous and ocular allergies, depression, obesity and alcohol consumption. RESULTS: The majority of asthmatic patients (75%) belonged to a low socio-economic environment with a salary lower than $200 per month. 31% were illiterate. 583 (1.3%) of patients on the database were asthmatic. The rate in children was higher (2.08%) than in adults (1.09%). The majority of asthma occurred among subjects from Bekaa valley and South Lebanon. Asthma was associated more strongly with being an ex-smoker (OR 4.37; 95% CI 2.38, 8.02) than being a current smoker (OR 1.44; 95% CI 1.11, 1.87). A significant and strong association was found with depression (OR 25.6; 95% CI 3.32, 197.6), obesity (OR 4.09, 95% CI 1.31, 12.73) and with regular alcohol consumption (OR 11.78; 95% CI 1.55, 89.44). CONCLUSION: This study describes the association of asthma in this population with low socio-economic status. By defining the demographic characteristics of the asthma population the Ministry of Health and the medical organizations concerned should be better able to manage the condition. This study confirms, in a Lebanese population, the epidemiological associations described in other populations around the world.

[Are narghile smokers different from cigarette smokers?]. / Les fumeurs de narghilé sont-ils différents des fumeurs de cigarettes?

BACKGROUND: The extent of smoking related health and economic problems is causing increasing alarm throughout the world. In the last few years a great number of subjects, especially in the developing world, have been smoking narghile and epidemiological studies on narghile smoking are an essential subject for investigation. The objectives of this study are to describe the social and cultural characteristics of narghile smokers in Lebanon compared to tobacco smokers. MATERIALS AND METHODS: Our sample is based on the data of 37579 subjects who consulted a non-governmental organisation (NGO), the Hariri Foundation, between 2003 and 2005. This NGO comprises 22 specialised centres distributed throughout Lebanon. The following data concerning exclusive narghile and cigarette smokers were collected: age, sex, the type and duration of tobacco addiction and the level of education. RESULTS: 13776 subjects (36.6% of the sample) were smokers of whom 88% smoked mostly cigarettes. 1529 subjects (11.1%) smoked narghile exclusively, a prevalence of 4.06%. The narghile smokers were younger than the cigarette smokers with a mean age of 36.2+/-8.63 years compared to 45.52+/-1.87 years. The majority of narghile smokers were women (56.57%) giving a male/female ratio of 0.77. A large number of narghile smokers were recent consumers with an exposure of less than 5 years. They differed from the cigarette smokers of whom the majority (72.2%) had smoked for more than 10 years. The proportion of illiterate subjects was greater among the narghile smokers (36.2%) than the cigarette smokers (24.2%). CONCLUSION: The consumption of tobacco is a real and frequent problem in Lebanon. The consumption of narghile is scourge that is gaining popularity, notably among women and the young. This problem is becoming a public health issue that needs to be taken into account within the framework of an anti-smoking policy in Lebanon.

[Intra-articular analgesia after arthroscopy of the knee]. / Analgésie intra-articulaire après arthroscopie du genou.

In 33 patients the authors compared two protocols for postoperative analgesia after elective arthroscopy of the knee. One group (n = 11) received plain bupivacaine 0.25% by intra-articular administration. Another group (n = 11) received by the same route a mixture of bupivacaine 0.25% with fentanyl 50 micrograms. The last group (placebo group: n = 11) received the same volume of saline. The combination of bupivacaine with fentanyl reduced postoperative pain more effectively than plain bupivacaine and the analgesic effect was still present 9 hours after the arthroscopy.

Prevalence of malnutrition in general surgical patients.

The possibility of protein-calorie malnutrition (PCM) was studied on one hundred consecutive patients admitted to the department of surgery at the Saint Georges Hospital, Beirut, during the months of April and June 1991, regardless of age, sex and socio-economic status. Data was completed on 94 of those cases. Multiple parameters were studied, including measurements of triceps and subscapular skinfold thickness, mid-arm muscle circumference, percent weight loss, creatinine height index, serum albumin and transferrin levels and total lymphocyte count. We found a prevalence of 81%, 65%, 53% and 31% of PCM, if one, two, three or at least four abnormal parameters are used respectively, to assess malnutrition. Defining malnutrition as the presence of at least three abnormal parameters, we conclude that 53% of the patients, on admission to the department of surgery, had evidence of PCM. Further studies are required to assess the impact of this prevalence on length of stay, morbidity and mortality.
