Five years cancer incidence in Aden Cancer Registry, Yemen (2002-2006).
(50/103)
The population-based Aden Cancer Registry (ACR) started its activities in 1997. The objective of the registry is to establish a reliable magnitude of cancer in the area covered and the first report was published in 2003. The present article describes data from the second report of cancer incidence over a five year period (2002-2006). Internationally accepted standardized cancer registration methodologies described by IACR and IARC were used. CanReg-4 using ICDO-3 and ICD-10 were applied in the data processing and analysis. Results showed no difference in the overall incidence between the males and females (ratio was 0.83:1) and age standardized rate s(ASR) per 100,000 inhabitants were 30.2 and 31.1. The five most common cancers were breast cancer, leukemia, non-Hodgkin's lymphomas (NH lymphoma), brain cancer and Hodgkin's disease (16.6%, 12.6%, 7.8%, 5.2% and 4.4%, respectively). Among males, leukemia was the first followed by NH lymphoma, Hodgkin's disease, brain and liver. In females, breast was the first, then leukemia, NH lymphoma, thyroid and brain cancer. The highest ASR for males (145 per 100,00 inhabitants) was observed at age 70-74 years whereas for females, two peaks (each 105 per 100,000 inhabitants) were equally noticed at age 60-64 and 70-74 years. Generally, females showed equal or higher incidence compared to males until age 55-59 where males reported higher incidence. The overall pattern of cancer incidence in this report is not much different from that in the previous report. Furthermore, the report generally indicates that the pattern of the most common registered cancer bears some similarities with the adjacent Gulf Cooperation Council States with which we share many characteristics, despite differences that warrant further investigation.

Daytime urinary incontinence among kindergarten children in Aden Governorate, 2003.
(52/103)
Daytime urinary incontinence is an involuntary or intentional voiding of urine in an awake child who is old enough to have developed control, and has a variable prevalence throughout the world. In Yemen, data regarding this problem are almost absent. In this study from the capital city of Aden, we aimed to: (1) determine the prevalence of daytime incontinence in kindergarten children aged 4-6 years, (2) identify the relation between daytime enuresis with personal and family characteristics of the children studied, and (3) describe the severity and characteristics of daytime enuresis in the studied children. A cross-sectional comparative study was undertaken in all kindergarten children aged 4-6 years in Aden Governorate and 1061 responded. Data were obtained by using a precoded self-administered questionnaire completed by the parents. The questionnaire consisted of two parts: personal and family characteristics of the studied children and the presence of daytime incontinence. The second part was responded if there was history of daytime incontinence, and contained information on the severity and possible associated factors. Daytime incontinence was encountered in 34 cases (3.2%); 18 were females. Significant differences between cases and incontinence-free children were encountered in birth order and type of kindergarten (P < 0.05). Majority (85.3%) had severe form of daytime incontinence. Bed wetting and combined day and night wetting were more frequent among males, whereas urinary symptoms (urgency, squatting, dysuria, dribbling) were more frequent among females. Working mother and frightening and emotionally stressful events in the 6 months preceding the study were significantly associated with daytime incontinence, while parents' education, punishment for daytime incontinence, and the presence of family history of incontinence were insignificant. In conclusion, this is the first study from Yemen reporting the prevalence of enuresis, similar to previous reports. Further studies are needed to explore this problem in our region to end the misery of the child and the family. (+info)
Prevalence of hepatitis C virus infection among hemodialysis patients in a single center in Yemen.
(53/103)
To evaluate the prevalence of anti-hepatitis C virus (HCV) among the hemodialysis patients and to identify the risk factors of infection in relation to age, sex, blood transfusions, duration of dialysis and primary cause of end stage-kidney disease. We studied 51 patients who were on chronic hemodialysis (HD) at the Al-Gamhourea Teaching Hospital, Aden, Yemen, during Jan-Dec 2007. All the patients were tested for anti-HCV antibody, and we used 100 healthy blood donors as controls. The anti-HCV antibody prevalence rate among the HD patients was found to be significantly higher than that in the control group (62.7% and 0.8%, respectively). The prevalence rate of anti-HCV antibody was higher among men (64%) than that in women (35%). The anti-HCV antibody-positive patients were significantly older than the anti-HCV-antibody-negative patients (66.5 +/- 14.4 years versus 57.5 +/- 15.4 years; P = 0.01). Diabetic nephropathy was a more frequent cause of end-stage renal disease among the anti-HCV antibody-positive patients (30%) than among the anti-HCV antibody-negative patients (19%). Among the anti-HCV-positive patients, 80% had received a blood transfusion, which was significantly higher than the 20% rate among the anti-HCV antibody-negative patients (P < 0.001). (+info)

Epidemiology of nocturnal enuresis in basic schoolchildren in Aden Governorate, Yemen.
(55/103)
Nocturnal enuresis is a common problem among children and adolescents. Data regarding this problem in schoolchildren in Yemen are scarce. This study was aimed to determine the prevalence of nocturnal incontinence in Aden school going children, describe its severity and identify the relation between nocturnal enuresis with personal and family characteristics. The study was a cross-sectional survey conducted on the public basic schoolchildren in Aden, Yemen, in the period November 2007-April 2009. A random, multistage sample of 890 students was taken from four districts in eight schools and divided into two strata: males and females. Data were obtained by using pre-recorded questionnaire, which was completed by parents. The response rate was 73.7% (656 students); 113 (17.2%) cases of nocturnal enuresis were encountered. Nocturnal enuresis decreased by age from 31.5% at 6-8 years to 8.7% at 15+ years (P < 0.05). Primary nocturnal enuresis affected 76.1%, of which the majority of children were bedwetting every night. Positive family history of nocturnal enuresis, deeper sleep, daytime enuresis, tea drinking, being non working father or with less education showed significant association with the occurrence of enuresis in the students. Stressful events in the previous 6 months of the study were twice more frequently noted. The study concluded that the prevalence of nocturnal enuresis in Aden public school children and its associated factors are almost comparable with that reported in epidemiological studies from various countries. Health education will encourage the parents to be aware, cope with this problem and seek appropriate medical advice. (+info)
