Juvenile xanthogranuloma is a benign cutaneous growth presenting as papules or nodules. It is characterized by an intradermal collection of lipid-laden macrophages and varying degrees of fibroblastic proliferation. We have recently observed two patients with xanthogranulomas: one was found to have a papular type and the second patient had multiple nodular growths. We present these cases, which should be considered in the differential diagnosis of skin nodules.

PMID: 8183163

We report a retrospective review of 12 medical students with a peculiar erythemato-vesicular dermatitis entomologically caused by an endemic beetle Paederus fuscipes. The clinical features, outcome in these cases and treatment are discussed. The students were residents of hostels in the USM campus in Kubang Kerian, Kelantan. The causative agent in all these cases were found to be Paederus fuscipes (rove beetle). The most common site of involvement in all these cases was the face, followed by the neck. The average duration of symptoms was two days and pruritus was a common symptom. About 83% of the patients made a complete recovery. However two patients (16%) had residual pigmentation.

Cavitary lung lesions of various etiologies may be encountered in patients with respiratory symptoms associated with fever. Non-malignant cavitary lesions may mimic malignant lung lesions on most of radiographic modalities including chest radiographs or thoracic computed tomography (CT). Primary lung malignancy can be detected in as high as one-fifths of CT thorax as cavitary lesions and the remaining aetiologies may be due to bacterial, parasitic, and invasive fungal infections, as well as Granulomatosis with polyangiitis (GPA), sarcoidosis, septic thrombo-embolism, and lung metastasis from extra-pulmonary primaries. We report an interesting case of melioidosis infection complicated with pulmonary embolism, both of which can lead to cavitary lung lesions and subsequently cause a clinical conundrum.

A previously healthy 80-year-old woman presented with a history of a thorn prick injury over the
distal phalange of her left finger obtained while gardening two months ago. She claimed to have a
non-healing cut with a nodular lesion, which progressively increased in size, extending upwards
towards the region of her left arm. There was no fever or palpable lymph nodes in the axillary region.
She had been prescribed antibiotics from the local hospital but her condition did not improve.

The Typhidot test, which detects IgM and IgG antibodies to a Salmonella typhi-specific outer membrane protein, is as sensitive as, and more specific than, the Widal test in the diagnosis of enteric fever in Malaysian children. It is easier and quicker to perform. In order to increase diagnostic accuracy in an area of high endemicity, the Typhidot-M test has been developed in which IgG is first removed. This theoretically allows improved detection of IgM, and thus would differentiate new from recent infections. We evaluated both tests in 134 unselected febrile children admitted to the General Hospital Kota Bharu, Malaysia. The children were divided into two groups: (i) those who were blood and/or stool culture positive for S. typhi and/or who had clinical features strongly suggestive of enteric fever (n = 62); and (ii) those who were both culture-negative and had clinical evidence of another diagnosis (n = 72). The sensitivity and specificity of the Typhidot and Typhidot-M tests were identical at 90.3 and 93.1%, respectively. Both tests had comparable sensitivity but greater specificity than those of the Widal test (91.9 and 80.6%, respectively). When used together, a positive result for Typhidot and/or Typhidot-M was more specific than either test alone (95.2%) but specificity was lower (87.5%). We conclude that the Typhidot and Typhidot-M tests have comparatively high diagnostic accuracy, suggesting that IgM can be detected in children who may have a predominant IgG response to S. typhi. Using these tests in combination increases the negative predictive value but at the cost of a lower positive predictive value.

BACKGROUND: Antiphospholipid syndrome (APS) is an autoimmune disorder characterised by thrombosis and/or pregnancy morbidity in the presence of antiphospholipid antibodies (aPLs) based on the Sydney criteria. We aimed to explore the clinico-laboratory features and treatment strategies of APS patients retrospectively.
METHODOLOGY: The medical records of APS patients registered under Hospital Universiti Sains Malaysia (Kelantan state) between 2000 and 2015 were reviewed.
RESULTS: A total of 17 APS subjects (age 40.7 ± 12.8 years) including 11 primary (64.7%) and six secondary APS (35.3%) patients were identified. The follow-up period was 9.5 ± 6.7 years with male:female ratio of 1.0:4.7. Pregnancy morbidity was the most common clinical manifestation (11/14; 78.6%) followed by recurrent venous thrombosis (10/17; 58.8%). For other clinical features, menorrhagia was the most frequently observed manifestation (4/14; 28.6%) followed by aPLs-associated thrombocytopenia (4/17; 23.5%) and ovarian cyst (3/14; 21.4%). LA and aCL were positive in 94.1% (16/17) and 81.8% (9/11) of the patients, respectively. APTT value (76.7 ± 17.0 sec) was significantly high (p < 0.05). Low intensity warfarin alone was successful to maintain target INR (2.0 - 3.0) and prevent recurrence of thrombosis.
CONCLUSION: The tendency of pregnancy morbidity in this cohort of Malaysian Kelantanese APS patients was high compared to other previously reported APS cohorts. Low intensity warfarin was successful in preventing recurrence of thrombosis, however, APS women receiving long-term anticoagulants should be monitored for possible occurrence of menorrhagia and ovarian cysts.

Porphyromonas gingivalis (P. gingivalis) is the primary periodontal pathogen involved in protein citrullination, which triggers the production of anti-cyclic citrullinated peptide (anti-CCP) antibodies, exacerbating rheumatoid arthritis (RA). This study aims to evaluate the amount of P. gingivalis and its association with anti-CCP antibodies in RA patients with periodontitis. This cross-sectional study involves 100 RA patients with a mean age of 52.36 (SD 13.90) years. Smokers and patients with other uncontrolled systemic diseases were excluded. Disease Activity Score-28 (DAS-28) was used to determine RA disease severity. Periodontal parameters were examined to determine periodontal status. Subsequently, plaque samples were collected from the subgingival periodontal pocket for assessment of P. gingivalis bacterial load using the loop-mediated isothermal amplification method. Blood samples (5 ml) were obtained from all participants to analyse anti-CCP antibody levels. Data was analysed by using SPSS version 24.0. Most participants were female (85.0%) and had low RA disease severity (62%). The mean RA disease duration was 7.77 (SD 6.3) years, with a mean DAS-28 of 3.17 (SD 1.0). Forty-seven per cent of participants had periodontitis, but all periodontal parameters were not associated with RA disease activity (P = 0.38). P. gingivalis bacterial load ranged from 10 to 109 copies/μl. Fifty-five per cent of the collected samples showed positive anti-CCP antibody levels, but no significant association was observed with the P. gingivalis bacterial load (P = 0.58). Considering the study's limitations, although periodontitis is prevalent among RA patients, there is a lack of association between P. gingivalis bacterial load and anti-CCP antibody levels, which should be investigated further.

INTRODUCTION: Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease of the joints with the involvement of other systems. Previous studies have demonstrated its association with chronic periodontitis (CP), a chronic inflammatory disease of tooth-supporting tissues. Positive rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) in RA patients have been found to be associated with CP. The aim of this study is to determine the prevalence of CP in RA patients, and to investigate the association of ACPA, RF status and RA disease activity with CP and non-CP RA patients.

MATERIALS AND METHODS: A comparative cross-sectional study involving 98 RA patients was conducted at Hospital Universiti Sains Malaysia, Kubang Kerian, Malaysia. Clinical oral examination was carried out to determine the CP status of RA patients. RF, ACPA and erythrocyte sedimentation rate (ESR) were measured, and the 28-joint Disease Activity Score (DAS-28) was assessed.

RESULTS: Forty-five patients (45.9%) were found to have CP (95% CI: 0.36-0.56). No significant difference was observed in the prevalence of positive RF (p=0.989) or ACPA (p=0.431) in CP and non-CP RA patients. There was also no significant association between active RA disease (DAS-28 score ≥3.2) and RF positivity in CP (p=0.927) and non-CP (p=0.431) RA patients as well as ACPA positivity in CP (p=0.780) and non-CP (p=0.611) RA patients.

CONCLUSION: In our cohort of RA patients, we did not find significant associations between elevated RF, ACPA, or active RA disease with the presence of CP. There were also no significant associations between elevated RF or ACPA with active RA disease.
