| Abstrak | : | Illustrations provided by Daniel Murrell, dansmurrell@gmail.com When I began teaching high school physics, I found that many of my students were not just struggling with the mathematics of physics but the way the language was used. Physics is sometimes discussed as being a second language where common words are coded with specific alternate definitions (consider how you use the word “delta”). Furthermore, many of our students are English Language Learners. Thus, providing developmentally appropriate assistance to building scientific vocabulary not only addresses equity issues but can be a highly effective teaching strategy. In this article, I provide an example of one such approach to addressing literacy issues: a vocabulary building story on Convection, Conduction, and Radiation. |

| Abstrak | : | Thanks to the COVID-19 pandemic, virtually all in-person instruction was shut down across the country in 2020 and beyond. This posed special problems for laboratory-based science courses, as those are defined by the conducting of experiments in person and often with specialized equipment unavailable outside of the classroom. Here I discuss a semester-long project for introductory astronomy that can be performed at home with very basic and inexpensive equipment. And, thanks to the vagaries of the orbits of the planets, variations of this activity can be carried out in many future semesters. |

| Abstrak | : | Neurogenic bladder is one of the most common complications of spinal cord injury (SCI), leading to impaired voiding function, recurrent urinary tract infections, and reduced quality of life. Determining the location, extent, and severity of the lesion is essentialto tailor management strategies to each patient’s neurological condition and functional status. Treatment includes non-surgical approaches such as intermittent catheterization, neuromodulation, and pharmacological therapy using anticholinergic drugs or 3-adrenergic agonists, which have been shown to reduce detrusor pressure. In cases unresponsive to conservative therapy,surgical interventions such as bladder augmentation or sacral nerve stimulation may be performed to preserve renal function, prevent vesicoureteral reflux, and achieve urinary continence. The prognosis is generally favorable when patients undergo longterm rehabilitation combined with comprehensive education and regular renal function monitoring. Multidisciplinary collaboration among urologists, rehabilitation specialists, and nurses plays a vital role in improving patient quality of life, reducing complications, and ensuring sustainable, effective management. |

| Abstrak | : | The emergency department (ED) operates 24 hours in a day, 7 days, in a a week, to provide emergency medical care, but with the growing number of visits, delays in patient assessment and treatment can impact care quality. A common performance indicator used to measure ED efficiency is the length of stay (LOS) of less than four hours, reflecting both service quality and patient flow management. This target has been widely implemented in a few countries, such as the United Kingdom and Australia to enhance ED operations. In Indonesia, a similar target has been set for national referral hospitals, aiming for 90% compliance. However, initial evaluations show that only a small fraction of hospitals meet this target, raising concerns about its feasibility. Despite these challenges, the four-hour LOS remains a relevant quality indicator in EDs. Achieving this goal requires collaborative efforts from allhealthcare stakeholders to improve ED efficiency and patient care. This literature review explores the feasibility and challenges of this target in all parts of Indonesia. |

| Abstrak | : | Hyperpigmentation is a dermatological condition characterized by increased melanin production which is the pigment responsible for skin color. Melanin is synthesized by melanocytes through an enzymatic pathway regulated by the enzyme tyrosinase. This process can be triggered by various factors such as ultraviolet (UV) radiation, hormonal changes, skin inflammation, aging, and the use of certain medications. One therapeutic approach is the use of natural ingredients, including herbal plant extracts. Glycyrrhiza glabra L., commonly known as licorice root, has long been used in both traditional and modern medicine due to its active compounds such as glabridin, which possesses antioxidant and tyrosinase-inhibiting properties. This review aims to evaluate the potential of licorice root extract as a natural depigmenting agent in the treatment of hyperpigmentation. A literature review was conductedusing databases PubMed, Google Scholar, NCBI, and ResearchGate. The findings indicate that glabridin selectively inhibits tyrosinase activity without causing skin irritation and also exhibits anti-inflammatory and photoprotective effects. Licorice root extract showspromise as a safe and effective natural therapeutic option for managing hyperpigmentation. |

| Abstrak | : | Postpartum hemorrhage is a leading cause of maternal death worldwide and remains a serious health concern, particularly in developing countries such as Indonesia. Accurate estimation of blood loss is essential for early detection of emergencies and for implementing rapid and appropriate interventions for patients. This review discusses several methods used to determine the amountof blood loss in obstetric cases, including visual estimation, quantitative measurement, and laboratory evaluation. The visual method is easily applied in primary health facilities but frequently underestimates blood loss due to lighting, fluid mixtures, and the experience of health providers. Quantitative methods, such as weighing blood-soaked materials or collecting blood in calibrated containers, are considered more objective and accurate. Laboratory assessment through hemoglobin concentration, hematocrit levels, and spectrophotometric analysis provides confirmation of clinical estimates. Combining quantitative and laboratory approaches can improve diagnostic accuracy, expedite clinical management, and ultimately reduce maternal morbidity and mortality associated with obstetric hemorrhage. |

| Abstrak | : | Ramp lesions are the most frequent intra-articular injuries associated with anterior cruciate ligament (ACL) ruptures and are often missed during diagnosis. They occur at the meniscocapsular junction of the posterior horn of the medial meniscus and may compromise knee stability. Magnetic resonance imaging (MRI) can identify ramp lesions but has limited sensitivity; therefore, arthroscopy remains the diagnostic gold standard. Treatment options include conservative management for stable tears and surgical repair for unstable or type IV–V lesions. Recent studies show no significant difference in long-term knee stability between repaired and unrepaired lesions; however, repaired lesions demonstrate faster functional recovery. Repair is particularly advised for patients in their productive years, especially athletes or individuals with high physical-activity demands requiring optimal knee stability. Appropriate radiologic evaluation combined with structured postoperative rehabilitation improves clinical outcomes and reduces recurrence. This review summarizes current evidence on the epidemiology, diagnosis, classification, and management strategies for ramp lesion |

| Abstrak | : | Leprosy or Hansen’s disease, is a chronic granulomatous infection caused by Mycobacterium leprae, which affects the skin and peripheral nerves. The disease occurs more frequently in males and remains a significant public health issue in endemic countries such as Indonesia. Case: A 23-year-old male presented with swelling of both hands, feet, and ears, accompanied by numbness and radiating pain. Dermatological examination revealed multiple erythematous papules and nodules that were anesthetic and symmetrically distributed, accompanied by onychodystrophy. Enlargement of the auricularis magnus and posterior tibial nerves was observed, as well as sensory disturbance in the ulnar nerve area. Slit-skin smear examination of the left ear showed acid-fast bacilli (2+ bacilli per field of view). Discussion: The patient was diagnosed with multibacillary-type leprosy with a type 2 reaction (erythema nodosum leprosum). This reaction represents a complex immune response that can lead to permanent nerve damage if not promptly managed. Conclusion: Comprehensive management involving a combination of anti-leprosy drugs, corticosteroids, analgesics, vitamin B complex, and medical rehabilitation is essential to prevent disability progression and improve functional outcomes. Patient education and regular follow-up are crucial for treatment success. The main challenge in this case is to prevent disability progression and maximize remaining function through comprehensive rehabilitation. |

| Abstrak | : | Low birth weight is defined by the World Health Organization as a birth weight of less than 2,500 grams, while extremely low birth weight is defined as a birth weight of less than 1,000 grams. Babies with low birth weight are 20 times more likely to experience complications and death compared to babies with normal birth weight. Case: A female infant, gestational age 28–29 weeks, birth weight 800 g, born spontaneously to a G3P1A1 mother with a history of premature rupture of membrane < 18 hours, urinary tract infection, and threatened preterm delivery. The infant cried immediately after birth, AS 7/9, and at 10 minutes appeared to be short of breath with a threat of respiratory distress. CPAP was administered, thermoregulation was performed, and intravenous antibiotics were given. Parenteral nutrition was given starting at 80 mL/kgBW/day and increased gradually. Breast milk was given on the second day starting at 20 mL/kgBW/day every 3 hours via OGT, increased by 10–20 mL/day according to tolerance. Complications during treatment included recurrent temperature instability, brown-colored vomit, and abdominal distension. The infant’s weight dropped to 700 g, and anemia (Hb = 10.6) developed. At 30 days of age, Kangaroo mother care, oral care, and physiotherapy were provided and taught to the parents. At 12 months of corrected age, the infant weighed 7.8 kg and was developing according to age milestones. Discussion: Early feeding plays a crucial role in the care of premature infants because it supports growth and gastrointestinal maturation. Enteral nutrition is better than total parenteral nutrition because it helps prevent problems from IV use, infections, side effects of total parenteral nutrition, and not eating. Conclusion: Prematurity is the leading cause of morbidity and mortality in neonates and children under 5 years of age. Proper management and good nutrition will support optimal growth, improve neurological outcomes, and reduce the incidence of sepsis and the possibility of retinopathy. |
