RESUMO
Cutaneous vasculitis presents with a variety of clinical morphologies and causes significant morbidity. A total of 85 patients with cutaneous vasculitis at Hospital Kuala Lumpur were retrospectively reviewed. Palpable purpura was seen in 49.4% and frequently involved the lower limbs (50.6%). Identifiable causes include drugs (28.2%), infections (20.0%) and connective tissue disorders (16.5%). Non steroidal antiinflammatory were the commonest group of drugs responsible for 25% of cases while B-haemolytic streptococci was the leading infectious cause (64.7%).

Pyoderma gangrenosum (PG) is an uncommon, chronic, painful, ulcerative skin disease of unknown origin, often associated with systemic diseases including inflammatory bowel disease, rheumatoid arthritis; monoclonal gammopathy, hepatitis and myeloproliferative disorders. The mainstay of therapy for PG has been high-dose corticosteroids but not all patients have a favourable outcome. Other systemic agents have also been used such as cyclosporine, azathioprine, cyclophosphamide and tacrolimus. However, all these systemic therapies can be complicated by serious side effects. In this paper, we report a series of four patients with pyoderma gangrenosum treated successfully with topical cyclosporine. No side-effects were observed in any of the patients and there was minimal systemic absorption of the topical cyclosporine.

The Malaysian Psoriasis Registry, established in 1998, is the first skin disease clinical registry in Malaysia. It aims to provide useful data on various aspects of psoriasis. Following an extensive revision of the registry form in 2007, a total of 509 psoriasis patients from 10 government dermatologic centres were reviewed in a three month pilot study. The onset of psoriasis was during the second to fourth decade of life in the majority of patients. There was no sexual and ethnic predilection. A positive family history was present in 21.2%, and more common in patients with younger disease onset. The main aggravating factors of psoriasis were stress, sunlight and infection. Plaque psoriasis was the commonest clinical type (80.9%). Joint disease was present in 17.3% of patients, among which mono-/oligoarticular type being the commonest. Nail changes occurred in 68%. More psoriasis patients were overweight and obese compared to the normal population. The mean Dermatologic Life Quality Index (DLQI) score was 8.08 +/- 6.29, and changes during subsequent follow-up may reflect therapeutic effectiveness. This study enabled evaluation of the revised registry form and helped in identifying shortcomings in the implementation of the registry.

Subcutaneous panniculitic T-cell lymphoma (SPTL) is a rare variant of cutaneous T-cell lymphoma where lymphoma cells infiltrate preferentially into subcutaneous tissue. Five cases of SPTL were seen during the period from 2001-2004 at the Department of Dermatology, Hospital Kuala Lumpur. All five presented with multiple subcutaneous nodules on the face, trunk and limbs of one week to six months duration with associated fever and loss of weight. Physical examination showed multiple tender, erythematous indurated plaques and subcutaneous nodules on their face, trunk and limbs. One patient also presented with unhealing ulcerated nodules. Two patients had hepatosplenomegaly and one hepatomegaly. Two patients had pancytopaenia while the other three had leucopaenia. One patient had deranged liver function. Out of the five patients, three had bone marrow examination with haemophaegocytosis in two and one hypocellular marrow. Skin biopsy of all patients showed infiltration with atypical lymphoid cells in the upper dermis and subcutaneous fat. These neoplastic cells showed positivity for CD3 and CD30 in three patients with CD8, TIA-1 and LCA (Leucocyte common antigen) being positive in one patient. One patient treated with prednisolone and subcutaneous Roferon 3Mu three times a week since 2001 was in remission. Two patients who were planned for chemotherapy had deteriorated rapidly and succumbed to septicaemia from pancytopaenia. Subcutaneous panniculitic T-cell lymphoma has been reported to show two distinct clinical presentations. The first is characterized by an indolent course with good prognosis and the second with rapid clinical deterioration, haemophaegocytosis and death. Both presentations were seen in our five patients seem to demonstrate these two subtypes of SPTL.

The usefulness of the direct immunofluorescent antibody technique--lupus band test--for the diagnosis of systemic lupus erythematosus (SLE) has been well established. The aims of the study were to determine the prevalence of the LBT at various sites of the skin in a cross section of patients with SLE and its correlation with disease activity. The LBT was demonstrated in 64% of skin lesions, 63% in non-lesional sun-exposed (NLSE) skin and 25% in non-lesional sun-protected (NLSP) skin. The prevalence of the LBT in lesional and NLSE groups was significantly different from the NLSP group (p = 0.03 and 0.005 respectively). There was a significant correlation between the presence of a positive LBT in NLSE skin with the presence of the LE cell phenomenon (p = 0.04) and anti - ds DNA antibody (0.02). In addition, there was a significant correlation between IgG LBT in the NLSE skin with serum hypocomplementaemia (p = 0.03) and anti - ds DNA antibody (p = 0.04). Other than these, no significant correlation was detected between the LBT from the 3 sites with overall clinical activity, renal disease, active skin lesions, or other laboratory indices of activity. These findings suggest that the LBT is mainly indicated as a diagnostic tool and has little role in assessing disease activity.

The clinical features and aetiology of 100 consecutive symptomatic heterosexual male patients with urethritis were studied from March 1994 to August 1994 in the Genito-Urinary Medicine (GUM) Clinic, Kuala Lumpur Hospital. Gonococcal urethritis (GU) was found to be more common (53%) than non-gonococcal urethritis(47%). All patients with GU confirmed microbiologically had clinically evident urethral discharge. Almost half (41%) of the patients with GU developed post-gonococcal urethritis (PGU). The most common organism isolated in PGU was Ureaplasma urealyticum (37%) whilst only 4% had both Chlamydia trachomatis and Ureaplasma urealyticum. Of the 47% of patients with non-gonococcal urethritis (NGU), 50% had no microorganism isolated, 32% had Ureaplasma urealyticum, 7% Chlamydia trachomatis and 11% both Chlamydia trachomatis and Ureaplasma urealyticum.

We report a 14 year old Indian-Muslim girl who developed a fulminant, disseminated and fatal varicella infection while receiving steroids for nephrotic syndrome. The terminal phase of her illness was complicated by a bleeding dyscrasia and circulatory collapse. Varicella infection in healthy children is a benign disease. However in neonates and immunosuppressed patients it may be severe and often fatal. There are many reports of fatalities occurring in cancer patients receiving chemotherapy, patients on immunosuppressives for asthma, haemolytic anaemia, rheumatic fever, and renal and bone marrow transplantation. Patients with nephrotic syndrome receiving cyclophosphamide treatment are at particular risk of developing severe chickenpox infection. To our knowledge, there has been only one report of fatal chickenpox infection in a child who received steroids for nephrotic syndrome. We report here a case of fatal haemorrhagic chickenpox complicating nephrotic syndrome.
