exudates and Dermatitis--Contact

Paederus fuscipes, a vector of Paederus dermatitis in most tropical and subtropical countries of the world have a high prevalence in human dwellings due to their positively phototaxic behaviour which has caused a tremendous impact on human health. In this paper, P. fuscipes dispersal flights were studied for two seasons of the rice cultivation phases in residential premises built close to rice field areas (≈32-60 m and 164 m) in mainland Penang, Malaysia. We examined the effects of different light illuminance, building floor level and their association with rice stages as a focal cause of P. fuscipes dispersion from the rice fields towards human dwellings. The present study showed a significant interaction between different light illuminances and rice cultivation phases in attracting P. fuscipes to disperse and invade human dwellings. The highest number of P. fuscipes was captured near the bright light. P. fuscipes flights increased in line with each floor level, and the highest captures took place at higher building floor levels (levels 2 and 3) compared to lower building floor levels (ground floor and level 1) of a three storey apartment in both rice seasons. This finding not only conveys a better understanding on P. fuscipes dispersal pattern, but also draws public attention on the occurrence of dermatitis linearis caused by the Paederus beetles.

We report a series of dermatitis cases caused by the staphilinid beetles, Paederusfuscipes Curtis, among university students staying in the residential college in Puncak Alam, Selangor, Malaysia from 1 January to 31 December 2010. A total of 360 cases (6.0%) were recorded in the Student Health Center throughout the year; the majority of patients stayed at a hostel near an oil palm plantation. Skin symptoms included erythema, edema, vesicular papules, painful blisters, burning sensation, pruritus, hyper pigmentation and peeling of skin. The commonly involved sites were the face, neck, shoulders and arms. Most students noticed the symptoms upon awakening in the morning. The patients were treated with fusidic acid cream and the symptoms resolved within 5 days. These beetles are nocturnally active and enter the room whenever a light source is available. The unintentional crushing of these beetles during sleep causes the release of its hemolymph (paederin) which is the cause of the dermatitis.

Domestic maid violence is an assault and coercive behaviour, which mainly includes physical, psychological and at times sexual too, by employer or household members of employer against a person hired as a domestic help. Maid abuse is well known but poorly documented in scientific literature. This is an important global issue. In this article, two illustrated cases of maid abuse are discussed. Their employers allegedly subjected both the victims to physical and psychological trauma. The physical examination of the victims showed poor state of clothing, nutrition, and presence of injuries of different duration. The bruises were irregular to patterned, and were inflicted by beating. Both cases had eczematous contact dermatitis over palms and soles, paronechia, and sub-ungal fungal infection due to unprotected working in wet conditions. In both cases, external ears were deformed like cauliflowers due to repeated trauma. All cases had multiple injuries of varying duration. In this paper, medico-legal and social issues related to maid abuse are also discussed in detail. A possible solution to minimise maid abuse is also suggested. This paper highlights and document maid abuse.

A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling.
