Testicular mass: do not forget filariasis

Ho CC, Ideris N

Infection, 2013 Aug;41(4):893-6.
PMID: 23471824 DOI: 10.1007/s15010-013-0443-x

Parasite infestation of the testicular tunica and spermatic cord by filariae are rarely reported and may present with few clinical signs, depending upon the stage. Occasionally, it may mimic a testicular tumor. We present a case of a 29-year-old man who presented with left testicular swelling and discomfort for 4 months. Clinical examination and imaging suggested an intrascrotal cystic lesion with a normal left testis. However, the intraoperative findings revealed a tumor-like mass; hence, a left orchidectomy was performed. However, histopathology reported a diagnosis of a cystic testicular tunica and spermatic cord with parasite infection. Here, we review the literature of scrotal and testicular parasite disease and discuss the course of the appropriate management involved.
Interaction of isothermal phase inversion and membrane formulation for pathogens detection in water

Low SC, Ahmad AL, Ideris N, Ng QH

Bioresour Technol, 2012 Jun;113:219-24.

The aim of this study was to explore the utilization of polymeric membrane for bio-sensing application in most efficient and rapid way. Customization of membrane formulation via phase separation study to modify its morphologies and properties enable the detection of different pathogens in a specific manner. Experimental findings (FESEM, through-pore distribution, porosity, capillary flow test and protein binding test) verified the predictions of faster capillary flow time and higher membrane's protein binding by the addition of cellulose acetate and nitrocellulose to the membrane casting dope, respectively. Throughout the phase separation study, the potential phase behavior was investigated, which was correlating various membrane structures to its performances for potential pathogens detection in water.
Optimization of polyvinylidene fluoride (PVDF) membrane fabrication for protein binding using statistical experimental design

Ahmad AL, Ideris N, Ooi BS, Low SC, Ismail A

J Immunoassay Immunochem, 2016;37(4):421-37.
PMID: 27088961 DOI: 10.1080/15321819.2016.1157489

Statistical experimental design was employed to optimize the preparation conditions of polyvinylidenefluoride (PVDF) membranes. Three variables considered were polymer concentration, dissolving temperature, and casting thickness, whereby the response variable was membrane-protein binding. The optimum preparation for the PVDF membrane was a polymer concentration of 16.55 wt%, a dissolving temperature of 27.5°C, and a casting thickness of 450 µm. The statistical model exhibits a deviation between the predicted and actual responses of less than 5%. Further characterization of the formed PVDF membrane showed that the morphology of the membrane was in line with the membrane-protein binding performance.
Fulltext A Cross-Sectional Study of Neutrophil-to-Lymphocyte Ratio in Diagnosing Acute Appendicitis in Hospital Melaka

Malays J Med Sci, 2019 Nov;26(6):55-66.
PMID: 31908587 DOI: 10.21315/mjms2019.26.6.6

Background: Acute appendicitis is one of the most common surgical emergencies. However, its proper diagnosis is complicated. This study aims to evaluate the ability of the neutrophil-to-lymphocyte ratio (NLR) to diagnose acute appendicitis in pre-operative state.
Methods: Histopathological examination of appendicectomies conducted between 2016 and 2017 in Melaka Hospital, Malaysia were traced and categorised into three groups: i) G1 (normal appendix), ii) G2 (acute appendicitis) and iii) G3 (perforated appendicitis). The reports were randomised and a total of 338 samples were collected. NLR values were compared between the three different groups and analysed.
Results: The median values of NLR for G1, G2 and G3 were 2.37, 5.25 and 9.27, respectively. We found a statistically significant difference in NLR between G1 and G2 (P < 0.001), and G2 and G3 (P < 0.001). The diagnostic values of NLR for acute appendicitis and perforated appendicitis were 3.11 (sensitivity: 75.23%, specificity: 68.70%) and 6.17 (sensitivity: 76.32%, specificity: 58.72%), respectively. There was a substantial correlation between NLR and disease severity, and a moderate correlation between NLR and duration of admission.
Conclusion: NLR, with a sensitivity of 75.23% and specificity of 68.70%, is a useful and reliable adjunct in diagnosing acute appendicitis. Hence, it will help in reducing the rate of negative appendicectomies.
