    Wilson disease is an inherited metabolic disorder. It is an autosomal recessive disorder caused by mutation of ATP7B gene, which results in excessive accumulation of copper in the body and deposition in various organs. The clinical presentation varies and neuropsychiatric manifestations are common. It is a diagnostic challenge in the initial phase where it mimics other psychiatric conditions and the diagnosis of Wilson disease is based on a combination of laboratory tests and clinical features. Wilson disease treatment comprises of copper chelating therapy such as D-Penicillamine and zinc sulphate wheras the behavior and mood symptoms response well with atypical antipsychotic treatment. The present report illustrates two cases of Wilson disease in middle-aged patients. The first presentation involved changes in behavior and personality. There was some delay in making the diagnosis in the initial stage. Both cases were diagnosed to have Wilson disease after further investigations. Their condition improved with the combination of copper chelating agent and atypical antipsychotic. In conclusion, it emphasizes the awareness of psychiatric manifestations as the initial presentation of Wilson disease.

    Penicillamine toxicity in Wilson's disease has been well reported but rarely seen now as newer agents are being used. We present a case who developed multiple rare complications of Penicillamine concurrently. Our patient is one of three siblings on Penicillamine, she was the only one who developed massive breast enlargement four months after commencing Penicillamine therapy, as well as dermatological adverse reactions and myasthenia gravis three more months later. All the adverse effects improved soon after substitution of the offending agent with Trientine.

    The aim of this study was to determine the effect of exogenous nitric oxide (NO) on the induction of murine splenic immune response to Aggregatibacter actinomycetemcomitans lipopolysaccharide (LPS) in vitro. BALB/c mice were immunized with A. actinomycetemcomitans LPS and a control group was sham-immunized. Spleen cells were obtained, cultured and stimulated with A. actinomycetemcomitans LPS with or without the presence of S-nitroso acetyl-penicillamine (SNAP), a NO donor, and carboxy-PTIO, an NO scavenger. Culture supernatants were assessed for inducible nitric oxide synthase (iNOS) activity, specific IgG subclass levels, and both IFN-gamma and IL-4 levels. The results showed that in A. actinomycetemcomitans LPS-stimulated cells, SNAP enhances iNOS activity but inhibits the levels of specific IgG2a and IFN-gamma suggesting a Th1 response. The effect of SNAP on these immune parameters was ablated by carboxy-PTIO. These results suggest that exogenous NO may suppress the Th1-like immune response of A. actinomycetemcomitans LPS-stimulated murine spleen cells.

    The clinical course of 18 patients with Wilson's disease is reported. There were 13 males and five females of whom one is Malay. The prevalence of Wilson's disease in Malaysia is probably the same as elsewhere. Being a genetic syndrome, the genetic carrier rate for Wilson's disease is probably lower amongst the Malays. At diagnosis, the clinical signs were predominantly hepatic in 10 patients, neurological in five patients with three asymptomatic cases. All patients were commenced on penicillamine but poor compliance was observed in many patients. Two patients defaulted follow-up and seven patients died. Out of the nine surviving patients, only four are well with no clinical symptoms.

    BACKGROUND AND AIMS OF THE WORK: Nitric oxide (NO) has been reported to enhance the production of cAMP by hydroxyapatite (HA)-induced a human osteoblast cell line (HOS cells). The aim of the present study was to test the hypothesis that exogenous NO may up-regulate the proliferation of hydroxyapatite (HA)-induced HOS cells via the cyclic-AMP-protein kinase A (PKA) pathway.

    Wilson's disease (WD), also known as hepatoleticular degeneration (HLD), is a rare autosomal recessive genetic disorder of copper metabolism, which causes copper to accumulate in body tissues. In this study, rats fed with copper-laden diet are used to render the clinical manifestations of WD, and their copper toxicity-induced organ lesions are studied. To investigate metabolic behaviors of 'decoppering' process, penicillamine (PA) was used for treating copper-laden rats as this chelating agent could eliminate excess copper through the urine. To date, there has been limited metabolomics study on WD, while metabolic impacts of copper accumulation and PA administration have yet to be established.

    Aim: This is a rheumatoid arthritis (RA) descriptive study, the first of its kind carried out in Malaysia.
    Methods: This descriptive study involved 1084 RA patients' epidemiological and clinical data taken from Selayang, Putrajaya, Taiping and Seremban hospitals from June 2004 to December 2005.
    Results: One thousand and eighty-four RA patients'data were analysed; 960 (88.6%) patients were female and 124 (11.4%) were male, approximately 8 : 1 M : F ratio. The majority of the patients were Indian (591; 54.5%), followed by the Malays (340; 31.4%), Chinese (126; 11.6%), indigenous (13; 1.2%) and others (14; 1.3%). Mean age was 49.6 ± 11.8 years with the youngest being 15 years and the oldest 88 years of age. Mean age for males was 52.0 ± 12.0 and females 49.3 ± 11.7 years (P =; 0.017). Most of these patients were housewives (565; 52.1%), followed by paid workers (266; 24.5%), retired patients (80; 7.4%), unemployed (76; 7.0%) and others (97; 8.9%). Mean duration of illness was 8.4 ± 6.7 years; 805 (74.3%) patients were relatively new patients (≤ 2 years illness duration) and 279 (25.7%) patients had illness duration > 2 years. Eight hundred and six (74.4%) were seropositive RA patients and 385 (35.5%) had presence of deformity. The majority of patients were treated with methotrexate (178; 16.4%), followed by combination of methotrexate, sulfasalazine and hydroxychloroquine (143; 13.2%), leflunomide (140; 12.9%), sulfasalazine (133; 12.3%) and combination of methotrexate and sulfasalazine (108; 10%).
    Conclusion: In the above study, the majority of patients were female (960; 88.6%), Indian (591; 54.5%), had a mean age of 49.6 ± 11.8 years, most were housewives with a mean duration of illness of 8.4 ± 6.7 years and were treated with methotrexate (178; 16.4%). The results of the study may help Malaysian rheumaologists to understand their patients better and treat RA holistically.
