Implementation of an AI model to triage paediatric brain magnetic resonance imaging orders
Dear Editor,
Artificial intelligence (AI) is viewed as the most important recent advancement in radiology with the potential to achieve Singapore’s objective of delivering value-based patient-centric care.1
We have developed and implemented a deep-learning model using bidirectional long short-term memory (Bi-LSTM) neural network to enable automated triage of unstructured free-text...

Tailoring the Field and Indication of Adjuvant Pelvic Radiation for Patients with FIGO Stage Ib Lymph Nodes-Negative Cervical Carcinoma Following Radical Surgery Based on the GOG Score – A Pilot Study
Although no significant survival difference exists between primary surgery and radiotherapy (RT) for the treatment of FIGO stage Ib cervical cancer, radical surgery is the preferred modality of treatment as conservation of the ovarian and vaginal function is of prime importance. It also allows the study of prognostic histopathological...

New Concepts in the Management of Optic Nerve Sheath Meningiomas
Optic nerve sheath meningiomas (ONSMs) account for one-third of primary optic nerve tumours, are the second most common optic nerve tumours after gliomas, and are the most common tumours of the optic nerve sheath. Although ONSMs are said to comprise 1% to 2% of all meningiomas, their reported incidence...

Hyperbaric Oxygen Therapy for Radiation-induced Optic Neuropathy
Radiation optic neuropathy (RON) is an infrequent but usually devastating consequence of radiation to the optic pathways. It is almost exclusively an iatrogenic phenomenon, occurring in patients who have undergone radiation therapy for tumours and other lesions in sites near the visual apparatus, such as the choroid, orbit, paranasal...

Electrocardiographic Changes in Patients with Cutaneous Leishmaniasis Treated with Systemic Glucantime
Antimonial compounds are regarded as the treatment of choice for cutaneous leishmaniasis (CL). The efficacy of sodium stibogluconate (pentostam) and the other compound of antimoniate meglumine antimoniate (glucantime) were reported in 1937 and 1946, respectively.

Application of the McDonald MRI Criteria in Multiple Sclerosis
Since its advent in 1982, magnetic resonance imaging (MRI) has become an important component in the evaluation of multiple sclerosis (MS). MRI is a highly sensitive tool for MS, with 95% patients with clinically definite MS (CDMS) demonstrating brain abnormalities.1 However, MRI is also known to be low in...

The Role of Surgery in High-grade Glioma – Is Surgical Resection Justified? A Review of the Current Knowledge
High-grade glioma (malignant glioma) is the most common primary intra-axial tumour of the central nervous system (CNS). Despite recent therapeutic advances in glioma treatment, the outcome for high-grade glioma has been disappointing. The first reported case of glioma resection was performed by Rickman Godlee in 1884.1 More than a...

Improvements in Quality of Care Resulting From a Formal Multidisciplinary Tumour Clinic in the Management of High-grade Glioma
Multidisciplinary care has now been established as the optimal management principle for the majority of malignancies.1,2 However, the model of multidisciplinary care, specifically the role of a formal multidisciplinary tumour clinic (MTC), remains unestablished outside of breast cancer care.2 There is minimal evidence to quantitatively assess the potential benefits...

Salvage Chemotherapy in Progressive High-grade Astrocytoma
High-grade astrocytoma includes glioblastoma multiforme (GBM) (World Health Organization grade 4) and anaplastic astrocytoma (AA) (WHO grade 3). These are the more common gliomas in adults.1 Treatment of these highly aggressive neoplasms remains a challenge. The infiltrative nature of astrocytoma or location of tumour in the eloquent brain precludes...

12th Yahya Cohen Memorial Lecture – The Cellular and Molecular Basis of Radiation-induced Sensori-neural Hearing Loss
Radiation-induced sensori-neural hearing loss (SNHL) has long been recognised as a complication of radiotherapy (RT) for head and neck tumours, if the auditory pathways had been included in the radiation fields. In Singapore, nasopharyngeal carcinoma (NPC) is common and the prevalence of SNHL after radiotherapy for NPC has been...

Germline Genetic Testing to Predict Drug Response and Toxicity in Oncology— Reality or Fiction?
There is an increasing interest in personalised medicine, perhaps none greater than in the field of oncology. The idea of making therapeutic decisions based on an individual’s genetic makeup, with the ability to predict tumour response, as well as minimise toxicity is extremely appealing to the oncologist. This is...
