Skin disease among staff in a large Korean nursing home

Scabies mimicking graft versus host disease in a hematopoietic cell transplant recipient

Scabies is a highly contagious skin infestation caused by the mite, Sarcoptes scabiei var. hominis. Complex responses to scabies mites in the innate, humoral, and cellular immune systems can cause skin inflammation and pruritus. Diagnosis can be challenging because scabies resembles other common skin conditions. We report the first Korean case of scabies in a hematopoietic cell transplant (HCT) recipient, initially suspected of skin graft versus host disease (GVHD). A T-cell acute lymphocytic leukemia patient underwent a sibling-matched allogeneic HCT and developed pruritus after cell engraftment. Treatment for GVHD did not improve the symptoms. He was diagnosed with scabies 30 days after the onset of symptoms.

[Scabies as an occupational disease]

Scabies is an infectious skin disease caused by the human itch mite (Sarcoptes scabiei var. hominis). It is mainly transmitted by direct skin-to-skin contact. The spread of scabies can cause major difficulties in healthcare institutions, particularly in residential homes for the elderly. The disease is characterized by intense nocturnal itching, erythematous papules arranged in a linear order, and scratching resulting in excoriations. The diagnosis is confirmed by identification of the mite or by finding one or more mite tunnels in the skin. An individually occurring case does not need to be reported. If two or more cases occur in the same institution, the company physician and the appropriate public health department are to be informed in Germany. In case of a suspected scabies infection in medical personnel due to exposure in their work setting, medical notification to the statutory occupational accidents' insurance (Nr. 3101) is to be issued in accordance with § 202, Volume VII of the German Social Code. First line treatment is topical therapy with 5 % permethrin. If scabies control is required in an institution, systemic treatment with ivermectin may be considered. In the case of a scabies outbreak, all patients, contact persons, and staff must be treated simultaneously.

Socio-demographic characteristics of children infested with scabies in densely populated communities of residential madrashas (Islamic education institutes) in Dhaka, Bangladesh

BACKGROUND

Outbreaks of scabies in institutions and the socio-economic consequences have not been reported from overpopulated countries such as Bangladesh.

STUDY DESIGN

A community-based study among children from six residential Islamic education institutes (madrashas) in Dhaka. Multistage random sampling was used.

OBJECTIVES

To study the socio-economic profile, water-sanitation facilities, personal hygiene and living conditions of these children.

METHODOLOGY

Direct interviews were used to collect the data and clinical check up was performed in all children.

RESULTS

In total, 492 children received clinical check-ups; 92.5% were boys (mean age: 11.2+/-2.4 years). 63.4% of fathers and 98.5% of mothers were either illiterate or had only received primary education, 55.1% of fathers were in low-paid labouring jobs, and 99% of mothers were housewives. Of the 98% of children who had scabies, 71% had been re-infected (96% during the winter). Randomly assigned anti-scabies drugs revealed an average cure rate of 85.5%. Seventy-four percent of children were living in poorly ventilated buildings with overcrowded sleeping arrangements. They had poor personal hygiene: 21% shared towels; 8% shared undergarments; 30% shared bed linen; and 81% kept their used clothes on a communal line or shelf. Sanitation was also poor: 39% bathed infrequently, although 97% carried out mandatory ablution. Most children (61%) washed their clothes (including undergarments) two or three times a fortnight, 35% did so every 2-3 days, and 3.7% washed their clothes on alternative days. Disease severity and re-infection were associated with infrequent washing of clothes (P<0.001) and bed linen (P<0.001), overcrowded sleeping arrangements (P<0.001) and infrequent bathing (P<0.001) with soap (P<0.001). This was further related to household income (P<0.001 for both).

CONCLUSION

The study findings have potentially dangerous implications for public health. Immediate attention should be given to developing a sustainable long-term intervention programme to combat scabies hyperendemicity, and to save thousands of children from impending complications.

Hand dermatitis among Korean nursing students

We used a previously validated questionnaire survey, which was translated into Korean and given to 270 students from a university-based nursing school in Seoul. A total of 202 questionnaires were received. The students' hand dermatitis prevalence ranged from 6.9% in the first year to 22.9% in the fourth year. Logistic regression indicated that students with systemic allergies were 4.2 times as likely to suffer from hand dermatitis. Year of study and living arrangements were also shown to have statistically significant correlations with hand dermatitis. Overall, this study suggests that hand dermatitis might be less prevalent among Korean nursing students when compared with their international counterparts. However, the identification of systemic allergies as a significant risk factor was consistent with previous reports from other countries.
