Skin problems after a tsunami

BACKGROUND: On December 26, 2004, the biggest earthquake for 40 years, measuring 9.0 on the Richter scale, triggered a tsunami that pounded the coastal areas of South Asia and East Africa. The effects of the tsunami on skin conditions have not been evaluated. OBJECTIVE: To determine the influence of the tsunami on skin conditions by evaluating the skin problems of patients presenting at hospitals after the tsunami. METHODS: Between 5 and 25 January 2005, two dermatologists evaluated patients who complained of skin problems at an outpatient clinic and emergency room of a general hospital in Banda Aceh, Aceh Province, Indonesia. RESULTS: The total number of patients that presented during the study period was 235 (131 males and 104 females), and they had a total of 265 skin problems. In terms of age distribution, most subjects were in their fourth decade (23.0%), followed by the third (22.6%) and fifth decade (16.6%). The most prevalent skin problems were infections-infestations (32.5%), followed by eczemas (29.8%) and traumatic skin disorders (29.4%). In males, traumatic skin disorders were most common. The great majority of infection-infestation cases involved superficial fungal infections. Contact dermatitis accounted for three-quarters of eczema cases, and mainly involved the arms (40.0%) and legs (27.1%). The majority of traumatic skin disorders were lacerations, punctures and penetrations, and the feet (44.7%) and hands (18.8%) were most frequently affected. CONCLUSIONS: Unhygienic conditions, exposure to a hazardous environment and contact with various objects during and after the tsunami probably increased the prevalence of infections-infestations, traumatic skin disorders and contact dermatitis. To prevent these problems and associated secondary bacterial infections, health-related education and early medical management are required.     

Grading static versus dynamic images of contact lens complications

Background: This study was conducted to investigate grading performance when estimating the severity of static versus dynamic images of contact lens‐related ocular pathology. Methods: Thirty‐eight subjects used the Efron Grading Scales for Contact Lens Complications to grade the severity of ocular pathological changes depicted in static and dynamic (movie clip) computer‐displayed images of each of the following contact lens complications: bulbar conjunctival redness, limbal redness, papillary conjunctivitis, corneal staining, corneal infiltrates and meibomian gland dysfunction. The viewing of static and dynamic images was separated by seven weeks. Results: Grades assigned to dynamic images were 0.6 and 0.7 grading scale units higher than those assigned to static images for limbal redness and papillary conjunctivitis, respectively (p < 0.0001 for both). No difference was observed for the other four complications. There was an apparent trend for grading variability to be reduced (that is, observers grading in closer agreement) when grading dynamic versus static images. Conclusions: Absolute grades based on an assessment of signs of pathology represented in static images may, in some instances, underestimate the true severity of the condition.     

CLINICAL FEMINISATION AND SEX HORMONE CONCENTRATIONS IN NIGERIAN MEN WITH CIRRHOSIS WITH AND WITHOUT HEPATOCELLULAR CARCINOMA

SUMMARY The study explored the incidence of clinical feminisation and the sex hormone levels of 18 Nigerian patients with liver cirrhosis (LC) alone and 18 patients with LC and hepatocellular carcinoma (HCC). The incidence (11%) of clinical feminisation in Nigerian patients was lower than values reported from other countries and there was no association between feminising signs and the sex hormone levels of the patients. Plasma oestradiol and sex hormone-binding globulin (SHBG) levels were significantly higher and testosterone lower in patients with liver diseases than in 18 age-matched normal controls. Serum concentrations of oestradiol were also found to be significantly higher in patients with LC alone than in those with LC and HCC. A possible promotive role for oestrogens in the development of HCC from the cirrhotic liver is discussed.     

Paternal Asthma is a Predictor for Childhood Asthma in the Consanguineous Families from the United Arab Emirates

Consanguinity is known to increase the burden of genetic disorders among offspring. However, the effect of consanguinity on a complex disorder like childhood asthma has not been studied previously. Therefore, we explored this relationship by studying the asthma prevalence in children between 6 and 14 years of age among the local Arab families of the United Arab Emirates (UAE) where consanguinity is known to be highly prevalent. A total of 1136 children from 295 families met our inclusion criteria. The prevalence of childhood asthma was higher among children in consanguineous families (43.3%) compared to non-consanguineous (22.6%, p < 0.001). There was a significant correlation between the degree of consanguinity and the number of asthmatic children per family (p = 0.0002). Girls from consanguineous families had proportionately more asthma (42.9%, p < 0.001) compared to boys (23.1%, p = 0.539).

Paternal asthma in consanguineous families increased asthma risk for both boys and girls (p = 0.021 for boys, p < 0.001 for girls), while maternal asthma had no significant impact on asthma in offspring. Prevalence of childhood asthma was significantly higher in consanguineous families. The significant asthma predictors for girls from the consanguineous families were the degree of consanguinity and paternal asthma. The only predictor for boys was paternal asthma. These interesting observations merit further studies on both larger samples and in other consanguineous communities for confirmation.
