INTRODUCTIONAdults with obstructive sleep apnoea (OSA) are well documented to be at high risk for cardiovascular abnormalities. Growing evidence suggests that OSA is also associated with cardiovascular consequences in children. The purpose of this review is to examine the available data on this association in children.

METHODSPrimary studies were extracted from a MEDLINE search limited to those published between 1970 and 2008. The keywords used included child, sleep disordered breathing, sleep apnoea, snoring, blood pressure and hearts. The relevant articles were selected by consensus between 2 authors.

RESULTSThe results suggested that OSA was consistently associated with hypertension. Meta-analysis of risk of hypertension in those with high apnoea-hypopnoea index was undertaken. A combined odds ratio equal to 3.15 was found (95% confidence interval, 2.01 to 4.93). There was evidence for increased sympathetic activation, decreased arterial distensibility and ventricular hypertrophy in children with OSA.

CONCLUSIONChildhood OSA is associated with blood pressure dysregulation. The association of OSA with other cardiovascular morbidities requires further study in view of the limited data available currently.

OBJECTIVE: Obesity has been shown to be associated with adverse outcomes in viral infections such as influenza, but previous studies on coronavirus disease 2019 (COVID-19) had mixed results. The aim of this systematic review is to investigate the relationship between COVID-19 and obesity. METHODS: We performed a systematic review and meta-analysis. A literature search of MEDLINE, EMBASE, Scopus, Web of Science, CENTRAL, OpenGrey and preprint servers medRxiv and bioRxiv was performed, with no restriction on language or date of publication. Primary outcomes of this study were intensive care unit (ICU) admission or critical disease, severe disease and mortality. Secondary outcome was a positive COVID-19 test. Meta-analysis was performed using OpenMeta-Analyst software, and heterogeneity was tested using Cochran's Q test and I2 statistic. The study protocol was registered on PROSPERO (CRD42020184953). RESULTS: A total of 1,493 articles were identified and 61 studies on 270,241 patients were included. The pooled prevalence of obesity was 27.6% (95% confidence interval [CI] 22.0-33.2) in hospitalised patients. Obesity was not significantly associated with increased ICU admission or critical illness (odds ratio [OR] 1.25, 95% CI 0.99-1.58, CONCLUSION Obesity increased the risk of severe disease, mortality and infection with COVID-19. Higher body mass index was associated with ICU admission and critical disease. Patients who are obese may be more susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and infected patients should be monitored closely for adverse outcomes.

Dermatomyofibroma is a rare benign cutaneous mesenchymal neoplasm of the fibroblasts and myofibroblasts. The majority of dermatomyofibromas present as red-brown discolored plaques or nodules, commonly located on the shoulder, upper arm, axilla, neck, and/or upper trunk. These lesions develop most frequently in young female patients at a mean of 28-years-of-age. Herein, a case of dermatomyofibroma is reported that developed in an infant. A 4-month-old boy presented with an ill-defined bluish firm plaque on the trunk that developed 1 month after birth. Histopathologically, there was proliferation of bland-looking spindle cells with fascicular arrangement in the dermis and subcutaneous tissue. Immunohistochemistry showed that most of the tumor cells expressed diffuse positivity for vimentin and smooth muscle actin, but were negative for S-100 protein, desmin, and CD34.

BACKGROUNDFalls are the most frequently reported adverse events in inpatient settings. We conducted a retrospective case-control study of inpatient falls within aged care wards in a tertiary hospital to investigate the associated characteristics of elderly patients suffering from falls and fall-related characteristics.

METHODSConsecutive retrospective cross-sectional design spanned July 2006 to December 2008.

PATIENT GROUPInformation on all aged care inpatients who suffered from 1 or more falls was extracted from Incident Information Management System (IIMS). Further details about the particular admission(s) were obtained from patients' medical records, e.g., patients' characteristics and circumstances surrounding the falls. Randomly selected aged care patients who did not suffer from a fall and who were discharged from the hospital in the same period served control group. Characteristics among patients with single fall and recurrent falls, as well as non-fallers were compared.

RESULTSOf the 438 falls evaluated, 71.9% occurred in patients' room and 18.9% in patients' bathroom/toilet. The common activities were moving/transferring and taking shower/toileting, respectively, 70.3%, 12.1% while occurring falls; and time of falls had a high peak during 9:00-11:00 a.m. Many were unassisted while falling. The common contributing factors for fall were intrinsic factors. Patients with recurrent falls were more likely to have lower Mini-Mental State Examination (MMSE) score. Logistic regression analysis showed length of stay longer than five weeks, dementia and stroke were independent risk factors for recurrent falls; and living in hostel/nursing home preadmission, needing assistance with mobility, cognitive impairment, stroke, incontinence and arthritis/osteoporosis were independent risk factors for fall.

CONCLUSIONSIn an aged care ward, falls are independently associated with recurrent factors. Cognitive impairment/dementia was a strong risk factor for falls, and main causes leading to fall were intrinsic factors. For patients with cognitive impairment/dementia and behavioral disorder providing special and effective interventions is of paramount importance for reducing the incidence of fall in an aged care ward in hospital settings.

The magnitude and potential duration of the current coronavirus disease 2019 (COVID-19) pandemic is something that most doctors currently in practice have yet to experience. While considerable information regarding COVID-19 is being published every day, it is challenging to filter out the most relevant or appropriate information for our individual practice. The Spine Society of Singapore convened via a teleconference on April 24, 2020 to collaborate on a national level and share collective wisdom in order to tackle the ongoing crisis. In the teleconference, 13 spine surgeons from across various hospitals in Singapore constituted the panel of experts. The following topics were discussed: repurposing of surgeons, continuity of spine services, introduction of telemedicine, triaging of spinal surgeries, preoperative testing, new challenges in performing spine surgery, and preparing for the post-pandemic era. While some issues required only the sharing of best practices, the Delphi panel method was adopted to form a consensus on others. Existing spine specific triage guidelines were debated and a locally accepted set of guidelines was established. Although preoperative testing is currently not performed routinely, the panel voted in favor of its implementation because they concluded that it is vital to protect themselves, their colleagues, and their patients. Solutions to operating room specific concerns were also discussed. This article reflects the opinions and insights shared during this meeting and reviews the evidence relevant to the issues that were raised. The rapid consensus reached during the teleconference has enabled us to be concerted, and thus stronger, in our national efforts to provide the best standard of care via our spine services in these challenging times. We believe that this article will provide some guidance for addressing COVID-19 in spine surgery and encourage other national/regional societies to conduct similar discussions that would help their navigation of this pandemic.

STUDY DESIGN: Retrospective study. PURPOSE: To identify the prevalence of severe headache occurring after cervical posterior surgical fixation (PSF) and to evaluate the clinical and radiological findings associated with severe headache after surgery. OVERVIEW OF LITERATURE: Several studies have reported on the axial pain after cervical surgery. However, to our knowledge, the incidence of severe headache after cervical PSF has not been elucidated. METHODS: The medical records and radiological assessment of patients who underwent surgical treatment from August 2002 to May 2012 were reviewed to identify the prevalence and risk factors for severe headaches occurring following PSF from C2 distally. Neck disability index scores (NDI) (the item for neck pain), the type of C2 screw, number of cervical fused levels (1–6), and smoking habit were calculated preoperatively and postoperatively. In addition, radiological parameters (T1 slope angle, C1/2 angle, C2–7 Cobb angle, C2–7 sagittal vertical axis and C1-implant distance) were assessed for all patients. Severe headache was defined as a high NDI headache score (>4 out of 5). RESULTS: Eighty-two patients met the inclusion criteria. The mean age was 59.2 years (range, 21–78 years), and the mean number of fused levels was 5.1. The mean follow-up period was 2.9 years (range, 1–10.9 years). While only one severe headache occurred de novo postoperatively in a patient in the C3 or C4 distally group (total 30 patients, average age of 50.2 years), 11 patients in the C2 distally group (p=0.04) had severe headache occur postoperatively. The radiological parameters were not significantly different between the postoperative milder headache and severe headache (SH) groups. The SH group had a significantly higher preoperative NDI score (neck pain) (p<0.01). CONCLUSIONS: Newly occurring severe headaches can occur in 18% of patients after PSF from C2 distally. The patients with newly occurring severe headaches had significantly higher preoperative NDI score (neck pain).

BACKGROUNDPercutaneous endoscopic gastrostomy (PEG) feeding is widely used in stroke patients suffering from persistent dysphagia; however, predicting the risks and benefits of PEG insertion in the individual patient is difficult. The aim of our study was to investigate if candidate risk factors could predict short-term mortality risk in poststroke patients who had PEG tube insertion for persistent dysphagia.

METHODSThis was a retrospective study of 3504 consecutive stroke patients admitted to two metropolitan hospitals during the period January 2005 to December 2013 and who also underwent PEG insertion for feeding due to persistent dysphagia.

RESULTSA total of 102 patients were included in the study. There were 22 deaths in 6 months after insertion of PEG tubes and 20 deaths of those occurred within 3 months post PEG. Those who survived beyond 6 months showed significantly lower mean age (75.9 ± 9.0 years vs. 83.0 ± 4.9 years, P < 0.001), a lower mean American Society of Anesthesia (ASA) score (3.04 ± 0.63 vs. 3.64 ± 0.58, P < 0.001) compared to nonsurvivors. In multiple Logistic, age (P = 0.004, odds ratio [OR] = 1.144; 95% confidence interval [CI]: 1.044-1.255); ASA (P = 0.002, OR = 5.065; 95% CI: 1.815-14.133) and albumin level pre-PEG insertion (P = 0.033, OR = 0.869; 95% CI: 0.764-0.988) were the independent determinants of mortality respectively.

CONCLUSIONSWe propose that age, ASA score and albumin level pre-PEG insertion to be included as factors to assist in the selection of patients who are likely to survive more than 3 months post PEG insertion.
