Gastric duplication cysts (GDCs) are rare congenital anomalies. Presentation of GDCs varies from an asymptomatic abdominal mass to fulminant or massive gastrointestinal (GI) bleeding. Herein, we describe a case of a GDC in a 10-month-old infant presenting with unexplained massive GI hemorrhage and hematemesis. An abdominal ultrasound was negative, while computerized tomography was, initially, inaccessible. Through a series of repeated esophagogastroduodenoscopies, we documented penetration of the GDC into the gastric cavity that was later confirmed by computerized tomography. The patient was treated successfully with surgical resection.

Objective:
The aim of this study was to introduce a gelatin/bovine serum albumin (BSA) tissue standard, which provides dissolution properties identical to those of biological tissues. Further, the study evaluated whether the utilization of endodontic activating devices led to enhanced phantom dissolution rates.
Materials and Methods:
Bovine pulp tissue was obtained to determine a benchmark of tissue dissolution. The surface area and mass of samples were held constant while the ratio of gelatin and BSA were varied, ranging from 7.5% to 10% gelatin and 5% BSA. Each sample was placed in an individual test tube that was filled with an appropriate sodium hypochlorite solution for 1, 3, and 5 minutes, and then removed from the solution, blotted dry, and weighed again. The remaining tissue was calculated as the percent of initial tissue to determine the tissue dissolution rate. A radiopaque agent (sodium diatrizoate) and a fluorescent dye (methylene blue) were added to the phantom to allow easy quantification of phantom dissolution in a canal block model when activated using ultrasonic (EndoUltra) or sonic (EndoActivator) energy.
Results:
The 9% gelatin + 5% BSA phantom showed statistically equivalent dissolution to bovine pulp tissue at all time intervals. Furthermore, the EndoUltra yielded significantly more phantom dissolution in the canal block than the EndoActivator or syringe irrigation.
Conclusions
Our phantom is comparable to biological tissue in terms of tissue dissolution and could be utilized for in vitro tests due to its injectability and detectability.

Purpose:
The practice of withholding oral nutrition for children hospitalized for critical asthma receiving continuous albuterol is not evidence based. We sought to characterize oral nutrition practices in this population and estimate the frequency of aspiration-related respiratory failure.
Methods:
We performed a single-center retrospective, matched cohort study of children 3–17 years of age admitted to a pediatric intensive care unit from Oct 2020 to May 2023 for critical asthma receiving continuous albuterol. Cases provided oral nutrition were matched 1:2 to controls withheld nutrition by age and National Heart Lung and Blood Institute asthma severity classification. The primary outcome was aspiration-related respiratory failure defined as any respiratory support escalation following observed aspiration. Descriptive data included demographics, anthropometrics, pediatric asthma severity scores, adjunct asthma interventions, continuous albuterol duration, mortality, and length of stay.
Results:
Of 36 cases and 72 matched controls, the mean age was 9.1±3.9 years and 66.7% had moderate-severe persistent asthma. Cases and controls had comparable anthropometrics and admission pediatric asthma severity scores. No aspiration-related respiratory failure events were observed even among those receiving nutrition concurrent to noninvasive ventilation.Compared to controls, cases experienced a longer continuous albuterol duration (median:1.1 [interquartile range: 0.7–1.8] versus 0.7 [interquartile range: 0.3–1.3] days, p<0.001).No differences in length of stay, adjunct interventions, endotracheal intubation rates, and mortality were observed between cases and controls.
Conclusion
For children hospitalized for critical asthma, oral nutrition during continuous nebulized albuterol appeared well tolerated. While prospective validation is required, the practice of withholding oral nutrition for continuous albuterol administration may be unwarranted.

Osteoporosis and Sarcopenia 2023;9(2):60-69
Objectives:
The aim of these Clinical Practice Guidelines is to provide evidence-based recommendations to assist healthcare providers in the screening, diagnosis and management of patients with postmenopausal osteoporosis (OP).
Methods:
A list of key clinical questions on the assessment, diagnosis and treatment of OP was formulated. A literature search using the PubMed, Medline, Cochrane Databases of Systematic Reviews, and OVID electronic databases identified all relevant articles on OP based on the key clinical questions, from 2014 onwards, to update from the 2015 edition. The articles were graded using the SIGN50 format. For each statement, studies with the highest level of evidence were used to frame the recommendation.
Results:
This article summarizes the diagnostic and treatment pathways for postmenopausal OP. Risk stratification of patients with OP encompasses clinical risk factors, bone mineral density measurements and FRAX risk estimates. Non-pharmacological measures including adequate calcium and vitamin D, regular exercise and falls prevention are recommended. Pharmacological measures depend on patients’ fracture risk status. Very high-risk individuals are recommended for treatment with an anabolic agent, if available, followed by an anti-resorptive agent. Alternatively, parenteral anti-resorptive agents can be used. High-risk individuals should be treated with anti-resorptive agents. In low-risk individuals, menopausal hormone replacement or selective estrogen receptor modulators can be used, if indicated. Patients should be assessed regularly to monitor treatment response and treatment adjusted, as appropriate.
Conclusions
The pathways for the management of postmenopausal OP in Malaysia have been updated. Incorporation of fracture risk stratification can guide appropriate treatment.
