Fulltext Latent toxoplasmosis in patients with different malignancy: a hospital based study

Nimir A, Othman A, Ee S, Musa Z, Majid IA, Kamarudin Z, et al.

J Clin Med Res, 2010 May 19;2(3):117-20.
PMID: 21629523 DOI: 10.4021/jocmr2010.06.375w

Seroprevalence of toxoplasmosis in different populations may vary according to different environments, social customs and habits. This study was designed to measure the seroprevalence of toxoplasmosis among patients with different malignancies and to ascertain the association between common risk factors and disease transmission.
Fulltext Septic arthritis in rheumatology: review of five cases

Muhayidina AD, Said MS

J Clin Med Res, 2009 Aug;1(3):173-7.
PMID: 22493652 DOI: 10.4021/jocmr2009.08.1254

This report illustrates five cases of patients admitted to medical ward in HUKM, diagnosed and treated as septic arthritis over the course of two months. Their age ranged from 32 to 67 years old with one patient had history of monoarticular pain and the other four had polyarticular pain. Two of these patients had pre-existing joint disease, namely gouty arthritis and rheumatoid arthritis, and another patient with background history of mixed connective tissue disease on long term steroid therapy. The diagnosis of septic arthritis was made mainly from clinical assessment, supported by synovial fluid assessment and blood investigations. All patients received minimum of two weeks intravenous antibiotic followed by one month course of antibiotic. All of them had arthrocentesis for diagnostic and therapeutic purposes and two had laparoscopic arthroscopy with wash out done.
Fulltext Rheumatoid arthritis: refractory to infliximab, a tumor necrosis factor inhibitor

Solehan HM, Said MS, Shaharir S, Rajalingham S

Rheumatoid arthritis is one of the commonest autoimmune diseases. It is a chronic, progressive, systemic inflammatory disorder affecting the synovial joints and typically producing symmetrical arthritis. If left untreated, it leads to joint destruction and thus deformity and disability.In the recent years, advances in molecular biology have led to a variety of new treatment approaches to rheumatoid arthritis and other systemic inflammatory diseases associated with autoimmunity. Anti tumor necrosis factor (TNF) agents are emerging in the frontline management of rheumatoid arthritis (RA) in the current era of biological treatment. We presented a 46-year-old Chinese female with a history of seropositive RA for the past 22 years refractory and intolerant to multiple medications including sulphasalazine (SSZ), leflunomide, hydroxychloroquine (HCQ) and methotrexate (MTX), thus infliximab, a tumor necrosis factor (TNF) inhibitor was initiated. However, despite receiving 6 cycles of infliximab therapy, she still complained of persistent disabled multiple joint pain and swelling. This report will discuss about rheumatoid arthritis, which is refractory to infliximab (a TNF inhibitor) and its alternative.
Fulltext Case review of sarcoidosis resembling Sjogren's syndrome

Ahmad Y, Shahril NS, Hussein H, Said MS

J Clin Med Res, 2010 Dec 11;2(6):284-8.
PMID: 22043264 DOI: 10.4021/jocmr482w

We would like to report a case of a 29-year-old male patient who presented with multiple lymphadenopathy and vague symptoms of low grade fever, cough, weight loss, rashes, vomiting, dry eyes and dry mouth. Physical examination revealed submandibular lymphadenopathy, vasculitic rashes over both lower limbs, and parotid gland enlargement. Blood investigations showed mild anemia with leukocytosis, predominantly eosinophilia and high erythrocyte sedimentation rate and C-reactive protein. Computed tomography of the neck, thorax and abdomen showed bilateral submandibular, submental adenopathy, mediastinal and para-aortic lymphadenopathy with generalized reticulonodular densities in both lower lobes. There were hepatomegaly and bilateral enlarged kidneys with renal cyst. Histopathological examination from the cervical lymph node later revealed non-caseating granuloma, consistent of sarcoidosis. Patient responded well to prednisolone 50 mg daily with subsequent reduction in the size of cervical lymphadenopathy and parotid swelling.

Fulltext Upper respiratory tract symptoms, renal involvement and vasculitis: a case report and review of wegener granulomatosis

Said MS

J Clin Med Res, 2010 Aug 18;2(4):189-93.
PMID: 21629538 DOI: 10.4021/jocmr412w

Wegeners Granulomatosis is a condition associated with systemic vasculitis which can present with upper respiratory tract symptoms initially. On September 2001, a 15-year-old girl presented with symptoms of nasal block for 3 weeks. She later developed joint pains and worsening renal status requiring dialysis. A renal biopsy was performed which showed pauci-immune cresentric glomerulonephritis. Her cANCA levels were positive. She was treated with oral cyclophosphamide and steroids and later responded.

Fulltext Impact of Drug Induced Long QT Syndrome: A Systematic Review

Arunachalam K, Lakshmanan S, Maan A, Kumar N, Dominic P

J Clin Med Res, 2018 May;10(5):384-390.
PMID: 29581800 DOI: 10.14740/jocmr3338w

Background: Drug induced long QT syndrome is quite common in daily clinical practice but its impact is unknown.
Methods: PubMed and EMBASE databases (until May 2, 2017) were searched to identify studies reporting drug induced long QT syndrome and followed the PRISMA guidelines. The main outcomes measured in these studies were QTc prolongation, ventricular arrhythmias, torsade de pointes (TdP) and death.
Results: Out of 176 non-duplicate reports, 36 studies satisfied inclusion criteria and provided data on patients exposed to drugs that can potentially cause long QT. Totally, 14,756 patients were exposed and 930 patients (6.3%) were found to have QTc prolongation. The number of males was 6,400 and females were 5,723 patients. The mean age of the patients was 43.8 ± 9.36 years. Ventricular arrhythmias were found in 379 patients (2.6%), 26 patients were found to have premature atrial contractions (PACs) and premature ventricular contractions (PVCs). TdP was found in 49 patients (0.33 %), sudden cardiac death (SCD) was found in five patients and 586 patients were found to have all-cause mortality.
Conclusions: Around 6% of patients have risk of QT prolongation when exposed but only 0.3% developed TdP and 2.6% developed ventricular arrhythmias. Risk of developing arrhythmias is higher with concomitant use of multiple QT prolonging drugs.
Fulltext Angiotensin-converting enzyme gene polymophism in adult primary focal segmental glomerulosclerosis

Mohd R, Wahab ZA, Cader R, Gafor HA, Radzi AM, Shah SA, et al.

BACKGROUND: Primary focal segmental glomerulosclerosis (FSGS) accounts for a third of biopsy-proven primary glomerulonephritis in Malaysia. Pediatric studies have found the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene to be associated with renal disease progression. The aim of this study was to determine the prevalence of the ACE (I/D) genotypes in adult primary FSGS and its association with renal outcome on follow-up.
METHODS: Prospective observational study involving primary FSGS patients was conducted. Biochemical and urine tests at the time of study were compared to the time of the diagnosis and disease progression analyzed. ACE gene polymorphism was identified using polymerase chain reaction amplification technique and categorized into II, ID and DD genotypes.
RESULTS: Forty-five patients with a median follow-up of 3.8 years (interquartile range: 1.8 - 5.6) were recruited. The commonest genotype was II (n = 23, 51.1%) followed by ID (n = 19, 42.2%) and DD (n = 3, 6.7%). The baseline characteristics were comparable between the II and non-II groups at diagnosis and at study recruitment except that the median urine protein-creatinine index was significantly lower in the II group compared to the non-II group (0.02 vs. 0.04 g/mmol (P = 0.03). Regardless of genotypes, all parameters of renal outcome improved after treatment.
CONCLUSION: The II followed by ID genotypes were the predominant ACE gene alleles in our FSGS. Although the D allele has been reported to have a negative impact on renal outcome, treatment appeared to be more important than genotype in preserving renal function in this cohort.
