Efficacy of Montelukast in Allergic Rhinitis Treatment: A Systematic Review and Meta-Analysis

Krishnamoorthy M, Mohd Noor N, Mat Lazim N, Abdullah B

Drugs, 2020 Nov;80(17):1831-1851.
PMID: 32915441 DOI: 10.1007/s40265-020-01406-9

BACKGROUND: In treating allergic rhinitis, montelukast has the potential to be used as an alternative or addition to an oral antihistamine or intranasal corticosteroid.
OBJECTIVE: The objective of this systematic review was to assess the effectiveness of montelukast in treating allergic rhinitis.
METHODS: An electronic literature search was performed using the Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE from 1966 to 21 January 2019. The eligibility criteria were randomized controlled trials comparing montelukast with placebo or other standard treatments. The primary outcomes assessed were daytime nasal symptom score (DNS) and night-time nasal symptom score (NNS). The secondary outcomes assessed were composite nasal symptom score (CSS), daytime eyes symptom score (DES), and rhinoconjunctivitis quality-of-life questionnaires (RQLQ). The meta-analysis was conducted using Review Manager 5.3 software based on the random-effects model.
RESULTS: Fifteen studies of 10387 participants met the inclusion criteria. Montelukast was more effective than placebo in improving DNS (mean difference [MD] - 0.12, 95% confidence interval [CI] - 0.15 to - 0.08; p
Candida Skull Base Osteomyelitis: a Case Report and Literature Review

Krishnamoorthy M, Othman NAN, Hassan NEB, Hitam SB

Acta Medica (Hradec Kralove), 2020;63(2):82-85.

Skull base osteomyelitis (SBO) also commonly known as malignant otitis externa was first described by Meltzer and Kelemen in 1959. Prior to the advent of the antibiotic era, this disease carried a poor prognosis with significant morbidity. It often proved fatal with mortality rates as high as 50%. Commonly seen in the immunocompromised patients, diabetes mellitus is an important associated comorbidity in the pathophysiologic development of this disease. Treatment is instituted by medical therapy with surgery having a limited role. Surgical intervention has a limited role, for example, in fungal SBO. Such cases may require local debridement and intraoperative tissue biopsies for histopathologic confirmation. This is to demonstrate fungal invasion into the skull base, as well as to exclude other sinister differential diagnoses like squamous cell carcinoma of temporal bone. In this case report, we present a rare case of candida SBO and the literature review.
Mantle Cell Lymphoma: A Rare Vallecular Tumour

Lo R, Mohamad S, Krishnamoorthy M, Mohamad I, Zulkarnain S, Hussain FA

Medeni Med J, 2020;35(1):67-70.
PMID: 32733752 DOI: 10.5222/MMJ.2020.22208

Vallecular lymphoma is an extremely rare tumour of oropharynx. We report a case of 61-year-old gentleman presented with severe dysphagia and globus sensation for two months. Patient underwent endoscopic transoral tumour debulking for diagnostic and therapeutic purpose. Histopathologically, patient was diagnosed as mantle cell lymphoma (MCL). In this case report, atypical presentation of the disease, histopathological features and its current treatments are discussed.
BiFeO3 immobilized within liquid natural rubber-based hydrogel with enhanced adsorption-photocatalytic performance

Krishnamoorthy M, Ahmad NH, Amran HN, Mohamed MA, Kaus NHM, Yusoff SFM

Semiconductor materials have shown a good photocatalytic behaviour for the photodegradation of organic pollutants. In this work, maleated liquid natural rubber (MLNR) based hydrogel supported bismuth ferrite (BiFeO3) as photocatalyst was successfully synthesized by crosslinking with acrylic acid (AAc) assisted by the ultrasonication method to study the efficiency for the removal of methylene blue (MB) dye in wastewater. Response surface methodology (RSM) was used to optimize the parameters for adsorption of the methylene blue (MB) dye compound, whereby the effects of the initial concentration of MB and the adsorption time were examined to obtain a quadratic model for the respective hydrogel composite. The prepared composite sample was characterized by Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX) and X-ray Diffraction (XRD) analysis. Remarkable improvement for removal of methylene blue (99% removal) was found within 3 h adsorption time with a MLNR/AAc-BiFeO3 hydrogel composite as compared to the pristine hydrogel. A synergistic mode of dye removal by adsorption and photodegradation is proposed. Based on the isotherm and kinetic study conducted, it was found that Freundlich isotherm model and a pseudo second-order kinetic model was best fitted for adsorption of MB dye. The MLNR/AAc-BiFeO3 composite maintains its removal efficiency after 5 cycles without the necessity of post-treatment separation. Therefore, it is crucial to note that the resultant low-cost MLNR/AAc-BiFeO3 hydrogel composite in this study offers excellent potential for water and wastewater treatment applications with improved recyclability and recovery.
