A Humanist Neurosurgeon: A Legacy of Dr. Roy Selby

Lichterman BL, Wong SN, Likhterman LB

World Neurosurg, 2019 Aug;128:149-157.
PMID: 31042604 DOI: 10.1016/j.wneu.2019.04.178

The article is dedicated to the life and work of Dr. Roy Selby (1930-2002), an American neurosurgeon who founded neurosurgery in Malaysia. Dr. Selby stayed in Malaysia from July 1963 to May 1970. He opened the first neurosurgical department at the general hospital in Kuala Lumpur and established a training program under which Malaysian physicians and nurses were sent to neurosurgery centers in the United States and Canada. Some physicians came back and headed local neurosurgical units. On his return to the United States, Dr. Selby practiced neurosurgery until 1986, when he had to give it up due to the impact of progressive congestive heart failure. From 1986 to 1994, Dr. Selby taught graduate courses in the Department of Psychology at East Texas State University, Texarkana, Texas. He was a pioneer of spinal surgery and founded the Lumbar Spine Society. Dr. Selby was a world citizen neurosurgeon and advocated international standards of training in neurosurgery. From 1985 to 1994, he was chairman of the Archives Committee of the American Association of Neurological Surgeons. Dr. Selby serves as a model of a physician as a humanist.

Early childhood is a period during which many factors influence the development of lifelong eating habits. This study aimed to assess the nutritional status of young children and to determine factors related to eating habits.
Fulltext Medical Technology: A Systematic Review on Medical Devices Utilized for Epilepsy Prediction and Management

BACKGROUND: Epilepsy is a devastating neurological disorder that affects nearly 70 million people worldwide. Epilepsy causes uncontrollable, unprovoked and unpredictable seizures that reduce the quality of life of those afflicted, with 1-9 epileptic patient deaths per 1000 patients occurring annually due to sudden unexpected death in epilepsy (SUDEP). Predicting the onset of seizures and managing them may help patients from harming themselves and may improve their well-being. For a long time, electroencephalography (EEG) devices have been the mainstay for seizure detection and monitoring. This systematic review aimed to elucidate and critically evaluate the latest advancements in medical devices, besides EEG, that have been proposed for the management and prediction of epileptic seizures. A literature search was performed on three databases, PubMed, Scopus and EMBASE.
METHODS: Following title/abstract screening by two independent reviewers, 27 articles were selected for critical analysis in this review.
RESULTS: These articles revealed ambulatory, non-invasive and wearable medical devices, such as the in-ear EEG devices; the accelerometer-based devices and the subcutaneous implanted EEG devices might be more acceptable than traditional EEG systems. In addition, extracerebral signalbased devices may be more efficient than EEG-based systems, especially when combined with an intervention trigger. Although further studies may still be required to improve and validate these proposed systems before commercialization, these findings may give hope to epileptic patients, particularly those with refractory epilepsy, to predict and manage their seizures.
CONCLUSION: The use of medical devices for epilepsy may improve patients' independence and quality of life and possibly prevent sudden unexpected death in epilepsy (SUDEP).
Fulltext South-East Asia study alliance guidelines on the management of acne vulgaris in South-East Asian patients

Goh CL, Abad-Casintahan F, Aw DC, Baba R, Chan LC, Hung NT, et al.

The management of acne in South-East Asia is unique, as Asian skin and local variables require a clinical approach unlike that utilized in other parts of the world. There are different treatment guidelines per country in the region, and a group of leading dermatologists from these countries convened to review these guidelines, discuss current practices and recent advances, and formulate consensus guidelines to harmonize the management of acne vulgaris in the region. Emphasis has been placed on formulating recommendations to impede the development of antibiotic resistance in Propionibacterium acnes. The group adopted the Acne Consensus Conference system for grading acne severity. The group recommends that patients may be treated with topical medications including retinoids, benzoyl peroxide (BPO), salicylic acid, a combination of retinoid and BPO, or a combination of retinoids and BPO with or without antibiotics for mild acne; topical retinoid with topical BPO and a oral antibiotic for moderate acne; and oral isotretinoin if the patient fails first-line treatment (a 6- or 8-week trial of combined oral antibiotics and topical retinoids with BPO) for severe acne. Maintenance acne treatment using topical retinoids with or without BPO is recommended. To prevent the development of antibiotic resistance, topical antibiotics should not be used as monotherapy or used simultaneously with oral antibiotics. Skin care, comprised of cleansing, moisturizing and sun protection, is likewise recommended. Patient education and good communication is recommended to improve adherence, and advice should be given about the characteristics of the skin care products patients should use.
Fulltext Meeting the Challenges of Acne Treatment in Asian Patients: A Review of the Role of Dermocosmetics as Adjunctive Therapy

Goh CL, Noppakun N, Micali G, Azizan NZ, Boonchai W, Chan Y, et al.

J Cutan Aesthet Surg, 2016;9(2):85-92.
PMID: 27398008 DOI: 10.4103/0974-2077.184043

Conventional acne treatment presents several challenges such as intolerable side effects and antibiotic resistance. Dermocosmetic products may be used to reduce these unwanted effects. Dermocosmetics include skin cleansers, topical sebum-controllers, skin antimicrobial/anti-inflammatory agents, moisturizers, sunscreens, and camouflage products. Appropriate use of these products may help augment the benefit of acne treatment, minimize side effects, and reduce the need for topical antibiotics. In Asia, there is currently limited scientific data on the application and recommendations for dermocosmetic use in acne vulgaris (AV). This article reviews the evidence on dermocosmetics for AV and provides practice recommendations as discussed during the 4(th) Asia-Pacific Acne Leaders' Summit held in Bangkok, Thailand, on 7 and 8 February 2015. Through a premeeting survey, a series of plenary lectures, a stepwise program of discussion sessions, and Medline article review, the Expert Panel set forth relevant recommendations on the role of dermocosmetics as adjunct for treating AV in Asian patients.
Fulltext Mutations in KEOPS-complex genes cause nephrotic syndrome with primary microcephaly

Galloway-Mowat syndrome (GAMOS) is an autosomal-recessive disease characterized by the combination of early-onset nephrotic syndrome (SRNS) and microcephaly with brain anomalies. Here we identified recessive mutations in OSGEP, TP53RK, TPRKB, and LAGE3, genes encoding the four subunits of the KEOPS complex, in 37 individuals from 32 families with GAMOS. CRISPR-Cas9 knockout in zebrafish and mice recapitulated the human phenotype of primary microcephaly and resulted in early lethality. Knockdown of OSGEP, TP53RK, or TPRKB inhibited cell proliferation, which human mutations did not rescue. Furthermore, knockdown of these genes impaired protein translation, caused endoplasmic reticulum stress, activated DNA-damage-response signaling, and ultimately induced apoptosis. Knockdown of OSGEP or TP53RK induced defects in the actin cytoskeleton and decreased the migration rate of human podocytes, an established intermediate phenotype of SRNS. We thus identified four new monogenic causes of GAMOS, describe a link between KEOPS function and human disease, and delineate potential pathogenic mechanisms.
