Marginal Mandibulectomy in Oral Cavity SCC: Experience in a Tertiary Care Centre.

Marginal mandibulectomy is indicated for oral cavity squamous cell carcinomas that involve floor of mouth, abut or minimally erode the mandible without gross invasion. Successful outcomes after Marginal mandibulectomy is predicated on accurate patient selection and appropriate adjuvant treatment based on specific host and tumor characteristics. To study the onclogical outcomes in terms of loco-regional recurrence free survival and disease specific survival of marginal mandibulectomy done for oral squamous cell carcinomas.

Allogeneic Umbilical Cord Plasma Eyedrops for the Treatment of Recalcitrant Dry Eye Disease Patients.

Background: Dry eye disease is a significant disease in Singapore. While there have been studies using allogenic cord serum for the treatment of dry eye disease, treatment of dry eyes with allogenic umbilical cord plasma drops has yet to be started in Singapore.

Purpose: To evaluate the effectiveness of umbilical cord plasma eyedrops for the treatment of recalcitrant dry eyes in a local Singaporean context.

Recent and advanced therapy for oral cancer.

Oral cancer is a common and deadly kind of tissue invasion, has a high death rate, and may induce metastasis that mostly affects adults over the age of 40. Most in vitro traditional methods for studying cancer have included the use of monolayer cell cultures and several animal models. There is a worldwide effort underway to reduce the excessive use of laboratory animals since, although being physiologically adequate, animal models rarely succeed in exactly mimicking human models.

The impact of SARS-CoV-2 treatment on the cardiovascular system: an updated review.

The coronavirus disease-2019 (COVID-19) pandemic has become a major global health problem. COVID-19 is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and exhibits pulmonary and extrapulmonary effects, including cardiovascular involvement. There are several attempts to identify drugs that could treat COVID-19.

Compositions and antimicrobial properties of binary ZnO-CuO nanocomposites encapsulated calcium and carbon from Calotropis gigantea targeted for skin pathogens.

Calotropis gigantea (C. gigantea) extract with an ecofriendly nanotechnology approach could provide promising antimicrobial activity against skin pathogens. This study investigates the antimicrobial capability of green synthesized binary ZnO-CuO nanocomposites from C.

The clinical spectrum of ocular bartonellosis: a retrospective study at a tertiary centre in Malaysia.

Background: Cat scratch disease (CSD) is a systemic illness caused by the gram-negative bacillus, Bartonella henselea, which can occasionally involve the ocular structures. The objective of this study is to evaluate the various clinical presentations of ocular bartonellosis at our institution. A retrospective review of the clinical records of 13 patients (23 eyes) with ocular manifestations of Bartonella infections over a 3-year period between January 2016 to December 2018 was undertaken at our institution.

Axillary dissection for breast cancer using electrocautery versus ultrasonic dissectors: A prospective randomized study.

Background: The major morbidities of modified radical mastectomy both short- and long-term are sequelae of axillary dissection. Flap complications, prolonged seroma, need for axillary drainage, wound infection, lymphedema, shoulder stiffness, and paresthesia are major causes for morbidity after axillary dissection. Different techniques have been implemented to tackle these problems.

Temporalis Muscle Flap in Head and Neck Reconstructions Is That Forgotten or Forbidden? Our Case Series and Review of Literature.

Temporalis muscle flap is a versatile flap which can be used for reconstruction after major head and neck resections, owing to its optimal bulk, constant and reliable vascularity, ease of access to recipient site, minimal donor site morbidity and relatively better cosmetic outcome compared to more bulky flaps like pectoralis major myocutaneous flap or deltopectoral flap. The flap can be used as a muscle flap, myofascial flap (muscle with temporalis fascia). We present our series of 12 cases of temporalis muscle flap reconstruction for various head and neck reconstructions.

A Genome Wide Study of Copy Number Variation Associated with Nasopharyngeal Carcinoma in Malaysian Chinese Identifies CNVs at 11q14.3 and 6p21.3 as Candidate Loci.

Background: Nasopharyngeal carcinoma (NPC) is a neoplasm of the epithelial lining of the nasopharynx. Despite various reports linking genomic variants to NPC predisposition, very few reports were done on copy number variations (CNV). CNV is an inherent structural variation that has been found to be involved in cancer predisposition.

Retinal Changes in Uncomplicated and Severe Plasmodium knowlesi Malaria.

Background: Plasmodium knowlesi causes severe malaria, but its pathogenesis is poorly understood. Retinal changes provide insights into falciparum malaria pathogenesis but have not been studied in knowlesi malaria.

Methods: An observational study was conducted in Malaysian adults hospitalized with severe (n = 20) and nonsevere (n = 24) knowlesi malaria using indirect ophthalmoscopy (n = 44) and fundus photography (n = 29).

High-frequency hearing loss among mobile phone users.

The objective of this study is to assess high frequency hearing (above 8 kHz) loss among prolonged mobile phone users is a tertiary Referral Center. Prospective single blinded study. This is the first study that used high-frequency audiometry.

Polymorphic variants of interleukin-13 R130Q, interleukin-4 T589C, interleukin-4RA I50V, and interleukin-4RA Q576R in allergic rhinitis: A pilot study.

The development of allergic rhinitis is considered to be caused by the complex interactions between genetic predisposition and environmental factors. Polymorphisms in the interleukin (IL)-13/4/4RA pathway have previously been shown to be associated with atopic diseases. The purpose of this study was to determine the association between IL-13 R130Q, IL-4 T589C, IL4 receptor alpha (IL-4RA) I50V, or IL-4RA Q576R polymorphisms and risk of allergic rhinitis in a hospital-based Malaysian population.

Identification of a functional variant in SPLUNC1 associated with nasopharyngeal carcinoma susceptibility among Malaysian Chinese.

Nasopharyngeal carcinoma (NPC) is a multifactorial and polygenic disease with high incidence in Asian countries. Epstein-Barr virus infection, environmental and genetic factors are believed to be involved in the tumorigenesis of NPC. The association of single nucleotide polymorphisms (SNPs) in LPLUNC1 and SPLUNC1 genes with NPC was investigated by performing a two-stage case control association study in a Malaysian Chinese population.

Patients with nasopharyngeal carcinoma demonstrate enhanced serum and tissue ceruloplasmin expression.

The proteomics approach was adopted to study the simultaneous expression of serum proteins in patients with nasopharyngeal carcinoma (NPC). We have subjected unfractionated whole sera of ten newly diagnosed Malaysian Chinese patients with WHO type III NPC to two-dimensional gel electrophoresis (2-DE) and image analysis. The results obtained were then compared to that generated from sera of ten normal healthy controls of the same ethnic group and range of age.
