Acute bacterial meningitis in adults: a hospital based study in Yemen.
(41/103)
Acute bacterial meningitis is an important cause of mortality and morbidity with high rates of long-term neurological sequelae. To determine the clinical presentation, complications, and outcome of acute meningitis in Yemen, a retrospective study in patients 15 years or older with acute bacterial meningitis who were admitted into Al-Thawra Teaching Hospital in Sana'a from January 2006 to December 2007 was carried out. There were 121 patients with acute bacterial meningitis. Lumbar puncture was performed in 112 (92.6%). The most common pathogen was Streptococcus pneumoniae found in 47.4% of positive cultures, Neisseria meningitidis in 33.9%, and Haemophilus influenzae in 10.2%. The classical triad of acute bacterial meningitis was found in 65% of cases. The mortality rate was 22.3%, with 27 patients dying during hospitalization. S. pneumoniae had a case fatality rate of 35.7%. Frequent complications were impaired consciousness, recurrent convulsion, and chest infection, which occurred in 30.6, 16.5, and 10.7% of the patients, respectively. Risk factors for death among those with acute bacterial meningitis included older age (>or=45 years), altered mental status, chest infection, and S. pneumoniae infection. This study highlights the importance of bacterial meningitis as a serious disease of adults in Yemen and the need for effective methods to prevent its complications. (+info)

Awareness and practice of breast cancer and breast-self examination among university students in Yemen.
(46/103)
BACKGROUND: Breast cancer (BC) is the most common cancer among females in Yemen and world-wide, Yemeni women are still facing an increasing threat to it in recent years and optimal chances for survival from BC in women can be achieved by detecting it early by Breast self examination (BSE). OBJECTIVE: To assess the knowledge, attitude and practice of breast cancer and breast self examination among female university students in Al-Mukalla city-2009. METHODS: a cross sectional descriptive study was carried out among 425 female university students in Al-Mukalla city by using self-administered questionnaire. RESULTS: the study indicated that majority of participants had low level of knowledge of BC 58.6%. Only 1.4% had gained high level of knowledge. 95.3% of participants believed BC is a serious disease. It was found that despite 76.9% of participants heard about BSE, only 17.4% of them were performing it. 55.9% mentioned lack of knowledge about technique of BSE as a barrier for not practicing BSE. Mass media 81.6 % and 67.3% was the first source of information about BC and BSE mentioned by the participants respectively. CONCLUSION: the majority of participants heard about BC, but their knowledge and understanding of the disease was very low. The most known method of BC detection was BSE, however the majority never practice it due to lack of knowledge about technique. (+info)
