    Skin diseases are common in children. However, only a very few prospective epidemiologic surveys are available in the literature. The present survey was directed at determining the spectrum and pattern of skin diseases of children in Kuwait. A total of 10,000 consecutive new patients were studied; 96% were children of Arab descent. A female preponderance (52%) was observed, and infants constituted the largest group within the patient population (28.7%). A total of 162 dermatoses were recorded. Atopic dermatitis was the most prevalent dermatosis (31.3%), followed by viral warts (13.1%), alopecia areata (6.7%), pityriasis alba (5.25%), psoriasis (4%), and diaper dermatitis (4%). Atopic dermatitis was the most frequently seen dermatosis in children of all age groups, whereas, viral warts were more prevalent in school-age children. The prevalence of alopecia areata and psoriasis was higher than reported earlier in other ethnic groups. A female preponderance was seen in children with alopecia areata, psoriasis, vitiligo, acne vulgaris, contact dermatitis, and pityriasis rosea. Dermatitis, superficial cutaneous infections, and nevi/nevoid disorders were the important groups studied.

    Most intra-abdominal and other types of fluid collections are now successfully drained percutaneously under image guidance. The utility of percutaneous drainage of tuberculous abscesses, especially those associated with osseous changes, is, however, less well established. Six patients with tuberculous iliopsoas abscesses were successfully managed by percutaneous drainage combined with antituberculous therapy. The abscesses were bilateral in one patient and unilateral in the other five. Drainage was by needle aspiration under ultrasound (US) guidance in one patient, and by catheter under CT guidance in the other patients. Three patients had associated osseous changes. There were no procedural complications. Tuberculous iliopsoas abscess can be successfully treated by percutaneous drainage and appropriate antituberculous therapy.

    BACKGROUND: Two natural rubber latex proteins, Hev b 1 and Hev b 3, have been described in spina bifida (SB)-associated latex allergy.

    OBJECTIVE: The aim of this study was to clone and express Hev b 3 and to obtain the immunologic active and soluble recombinant allergen for diagnosis of SB-associated latex allergy.

    METHODS: A complementary DNA (cDNA) coding for Hev b 3 was amplified from RNA of fresh latex collected from Malaysian rubber trees (Hevea brasiliensis). PCR primers were designed according to sequences of internal peptide fragments of natural (n) Hev b 3. The 5'-end sequence was obtained by specific amplification of cDNA ends. The recombinant (r) Hev b 3 was produced in Escherichia coli as a 6xHis tagged protein. Immunoblotting and inhibition assays were performed to characterize the recombinant allergen.

    RESULTS: An Hev b 3 cDNA clone of 922 bp encoding a protein of 204 amino acid residues corresponding to a molecular weight of 22.3 kd was obtained. In immunoblots 29/35, latex-allergic patients with SB revealed IgE binding to rHev b 3, as did 4 of 15 of the latex-sensitized group. The presence of all IgE epitopes on rHev b 3 was shown by its ability to abolish all IgE binding to nHev b 3. Hev b 3 is related to Hev b 1 by a sequence identity of 47%. Cross-reactivity between these 2 latex allergens was illustrated by the large extent of inhibition of IgE binding to nHev b 1 by rHev b 3.

    CONCLUSION: rHev b 3 constitutes a suitable in vitro reagent for the diagnosis of latex allergy in patients with SB. The determination of the full sequence of Hev b 3 and the production of the recombinant allergen will allow the epitope mapping and improve diagnostic reagents for latex allergy.

    BACKGROUND: Although pemphigus is a well-characterized entity, detailed epidemiologic studies from the Arabian Peninsula are not available. The purpose of this study was to elucidate the clinical features, course, and prognosis of pemphigus patients followed at a national dermatology center in Kuwait.

    METHODS: Fifty-four patients with pemphigus in this report were treated between 1981 and 1996, and were studied for several clinical features, treatment, course and prognosis.

    RESULTS: Around 80% of pemphigus patients were Arabs, and Kuwaitis constituted the largest number (46.3%) with a female predominance (F: M = 2:1). Pemphigus vulgaris (PV) was the commonest clinical type. The mean age of onset was 36 years. The follow-up period ranged from 2 months to 12 years (mean, 4.5 years). The majority of the patients could be managed with low-dose steroids (30-60 mg/day). Twenty per cent of the patients were in complete clinical remission and were off systemic therapy for an average of 3 years. No death secondary to the disease or its treatment was observed.

    CONCLUSIONS: Kuwaiti patients with pemphigus were observed to have a relatively young age of onset and a female predominance. Low doses of steroids were enough to control the disease in the majority, and at least 20% of patients were off therapy and in complete remission on follow-up.

    From the extract of a Malaysian herbal medicine, Lemuni Hitam (Diospyros sp.), which exhibited monoamine oxidase (MAO) inhibition, three new naphthoquinone and/or naphthalene dimers (lemuninols A-C, 1-3) were isolated together with 4,6-dihydroxy-5-methoxy-2-methyl-naphthalene (8) and six known monomers (4-7, 9 and 10). The structures were determined by spectroscopic methods including 2D-NMR techniques. Among them, lemuninol A showed 45% inhibition of MAO (mouse liver) at 5.0 x 10(-6) g/ml, and lemuninols B and C and a naphthoquinone (9) indicated weak activity. Some related quinones were also tested for their MAO inhibitory activities.

    A survey of career choices was conducted for two batches of physicians applying for a medical speciality course in Malaysian medical schools. There were a total of 952 applications, with 477 males and 475 females. Surgery ranked highest, followed by obstetrics and gynaecology, fanlily medicine and orthopaedic surgery. The minor specialities of otorhinolaryngology, psychiatry and pathology were the least popular choices. Questionnaires were sent to a random sample of 250 physicians in each batch to note factors affecting their choices of speciality. A total of 359 physicians responded, giving a response rate of 71.8%. Fixed hours of work and the ability to have direct contact with patients were relatively important factors for choice of speciality. Working as a clinical consultant was the nlost popular nature of employment while worliing in the health office, service consultant in a public hospital, a non-clinical lecturer in a university hospital and working in a private clinic were less popular choices for these physicians.

    A survey of malnutrition and helminth infections among 268 pre-school children living in the Kuala Betis Orang Asli resttlement villages in Kelantan. The prevalence of helminth infections was 47.4% with Ascaris lumbricoides being the most common helminth (43.9%), followed by Trichuris trichiura (29.7%) and hookworm (6.3%). The prevalence of Ascaris lumbricoides and Trichuris trichiura infections increased with age, with the highest prevalence found in the 6-7 years age group. The overall prevalence of stunting, underweight and wasting were 61.7%, 60.4% and 17.5% respectively. Both stunting and underweight were significantly higher among the infected children. Factors associated with helminth infections in the pre-school children were older age group, poor water supply and households with more than 5 members. Rountine regular deworming is recommended based on the World Health Organisation recommendations for school children.

    A restropective study on a case of recurent salmonellosis in a 3 month old child due to Salmonella bovismorbificans and Salmonella matopeni was carried out using pulsed field gel electrophoresis (PFGE) and antibiotic susceptibility analysis. PFGE clearly distinguished the two serovars and that the recurrent infection was shown to associated with variant forms of Salmonella bovismorbificans. The chromosomal changes detected among the seqential isolates of Salmonella bovismorbificans appeared to be associated with varing antibiogram patterns. The study also showed that the recurrent infection in the patient could be related to prolonged antibiotic therapy.

    Angioedema due to whatever cause is potelltially life threatening, especially if it involves the head and neck region. Patients at risk need to be identified and precautionary measures are necessary. The use of Angiotensin Converting Enzyme Inhibitors (ACEIs) has been associated with angioedenia of the face and tongue. Its widespread use has resulted in an increased awareness of this rare but important camplication. We report liere a case of angioedenla secondary to ACEls developing a few months after initiation of therapy and discuss its clinical importance.

    Anaemia in patients on renal replacement therapy is a cornmon problem and response to treatment with erythropoietin may be limited by functiollal iron deficiency. We recently studied prospectively for 22 weeks the effect of iron supplemetltation via intramuscular and oral vs intramuscular vs oral routes in 16 patients on chronic haemodialysis with renal anaenlia treated with erythropoietin injections. The rise in haemoglobin was significant in all patients except those on intramuscular iron only. This study supports unconfirmed observations that oral iron supplementation may be effective in patients with renal anaemia associated with functional iron deficiency.

    Activation of the synlpathetic nervous system (SNS) and renin-angiotensin system (RAS) plays a pivotal role in the pathophysiology and progression of the disease in chronic heart failure (CHF). Blocking the activation of the RAS with angiotensin converting enzyme inhibitors not only improves sylnptonls but also prolongs life in symptomatic CHF. Does a similar analogy hold true for the use of ß-blockers in CHF? Evidence from a number of small trials and several recent large prospective trials show that b-blockers may improve ventricular function and symptoms in CHF. In a combination of trials investigating the use of carvedilol (an α, and ß-blocker) in congestive heart failure a mortality benefit appears to be evident. There are still a number of key questions that relnaill unanswered regarding the tolerability, patient type and stage of CHF in which ß-blockers should be advocated. Several large scale trials are in progress to answer some of these questions and also to add further information regarding its efficacy and impact on survival.

    The aim of this review is to critically analyse the available literature and to propose a rational, safe and cost-effective clinical pathway to provide nutritional support in acute pancreatitis. This pathway is proposed based on assessment of peer reviewed literature and existing generally accepted knowledge. Acute pancreatitis is a heterogeneous disease and the outcome is variable. The role of nutritional support is controversial. Acute mild pancreatitis (80%) usually does not require nutritional support unless the pre-existing nutritional is poor or complications occur. Contrary to this acute severe pancreatitis is associated with severe catabolism and a high complication rate. Nutritional depletion rapidly occurs. It is logical to support the nutrition once the patient is haemodynamically stable. Although enteral nutrition should be administered whenever feasible, it is not always possible or advisable. Aggressive, hypercaloric parenteral nutrition administered via central venous line is not recommended. A combination of initial peripheral parenteral nutrition with fat in appropriate amount, and gradually switching over to enteral feedings is safer and cost-effective. It also avoids central line associated sepsis. The roles of newer specific therapeutic diets to enhance the immune status in patients with acute pancreatitis are not well established.

    100 consecutivnee wly diagnosed patients with nasopharyngeal carcinoma (NPC) since January 1994 were the subjects for studying various factors related to the delay in the confirmation of the diagnosis. 79 of them were ttlales and the peak age of incidence was the 5th decade. 92% of them were Chinese, 7% Malay and 1% Indian. 76% were agriculture worker or labourers with 66% having either no formal education (16%) or only primary level education (50%). For 50% of patients neck swelling was the first symptom, 26% had nasal symptoms, 12% ear symptoms and 11% hads symptoms due to intracranial extension of tumour. As many as 80% were at UICC Stage IV at the time of diagnosis. While the median delay, on the part of patients, in consulting a doctor was 2.5 days, the median delay on the part of the doctors to confirm the diagnosis of NPC was as long as 127 days, which was particularly worse when the patients presented with ear symptoms (266 days) followed by those with neck swelling (94 days). For those patients who were required to undergo more than one nasopharyngoscopy and biopsy the median doctor's delay was 144 days. Since 82% of patients had consulted general practitioners who remained the first-line health-service provider, it is suggested that their level of awareness with regards to NPC be significantly raised so that the delay on their part be greatly minimized.

    The requirement of the medical graduate, tabled in the objectives of undergraduate medical education, as envisaged by the Malaysian Medical Council, call for the all round basic doctor to be able to handle any medical emergency, as well as meet the requirements of law in examining, documenting and reporting on the common offences of the Penal Code, where medical documentation is required of law for the purposes of dispensing justice. However, in tabling the amended requirements of the undergraduate syllabus on the lines of those followed in sollie of the more developed nations, we seem to have lost this perspective. The authors discuss, based on his previous experience from another former colonial country viz. India, where the objectives of the undergraduate training is the same, and the influences 011 the legal profession bear a common origin and governance, the relevance of some of these topics, coming under the antbit of Forensic Medicine and Toxicology as an undergraduate subject, in the day-to-day practise of medicine in and out of government service. While this issue has been the frequent topic of discussion in international confereilces and symposia, where the decline in the standards of medico-legal work in the coulltries attending have been blanled on the fall in the standard of undergraduate teaching, due recognition of the pitfalls of the deletion or whittling down of the course content, independent of the overall overhauling of the syllabi of medical schools, to keep up to the trends of overseas universities, has not been accorded in the planing of the coursc revisions, resulting in a deletion of a vital aspect of daily practise of medicine.

    Dengue 2 New Guinea C (NGC) virus NS3 protein, a potentially important virulence factor was cloned to the N-terminus of the Aeqirorea victoria enhanced green fluorescent protein (EGFP) using the pEGFP-N1 mammalian expression vector. During amplification of the recombinant plasmid in E. coli, transformants expressing the EGFP were detected in vivo when viewed using fluorescence microscopy. This inadvertent expression of the recombinant fusion protein was confirmed further by detection of the T7.Tag peptide cloned to the aluino terminal of the fusion protein using T 7.Tag specific monoclonal antibody. These findings represent perhaps the first reported expression of the T7.Tag-NS3-EGFP fusion protein using the pEGFP-N1 mammalian expression vector in E. coli.

    In vitro lymphocyte proliferative response of peripheral blood leucocytes (PBL) to purified Toxoplasma gondii antigen were evaluated by 3[H] methyl thymidine incorporation in patients acutely and chronically infected with Toxoplama gondii. PBL from three patients with acute sylnptonlatic toxoplaslnosis showed no response to T. gondii antigen during the emergence of anti-Toxoplasma 1gM antibodies and the response returned as the infection became chronic. Lymphocytes of twelve chronically-infected patients responded positively to the antigen. In all patients the lymphocyte proliferative response to the mitogen, Concanavalill A (Con A) was normal. Analysis of Toxoplasma proliferative response of PBL from a patient with acute toxoplasrnosis showed that CD8+ cells were responsible for induction of suppression while the response during the chronic infection was lnediated by CD4+ cells. In human toxoplasmosis there was antigen-specific lymphocyte unresponsiveness during the acute phase of the infection and it appears that the initnunesuppression was mediated by CD8+ cells.
