| Abstrak | : | Aging is a life cycle stages accompanied by physiological and anatomical changes as biological aging process. Various methods of prevention and management are used to reduce the appearance of facial aging, among others is minimally invasive procedure. Dermal fillers or soft tissue fillers are one of the minimally invasive procedures aimed at restoring facial volume and augmenting specifc areas. Dermal fillers are divided into two categories, non-biodegradable and biodegradable. Biodegradable fillers are known as collagen stimulators.The use of collagen stimulators such as polycaprolactone (PCL), calcium hydroxylapatite (CaHa), and poly-L-lactic acid (PLLA) is increasingly popular due to their ability to stimulate natural collagen production, resulting in long-lasting and natural-looking outcomes. Each type has unique characteristics, indications, and injection techniques, making product and method selection important for optimal patient results. Side efects such as edema, nodules, or infammatory reactions can be minimized with proper technique and administration by trained medical professionals. With advances in technology and improved understanding, collagen stimulators have become an efective solution for soft tissue rejuvenation and augmentation in aesthetic practice. |

| Abstrak | : | Acute limb ischemia (ALI) is a rare occurrence in children, predominantly associated with trauma or iatrogenic causes. Acute limb ischemia can result in the loss of limbs and lifelong complications. The ideal treatment is not yet established. Case: A 10-month-old boy was referred with darkening of the extremities, accompanied by fever and seizures. The patient had a continuous fever for the past four days and experienced four generalized seizures, 1-2 minutes each. During treatment at the previous hospital, the nose and fingers of all extremities became dark blue since one day before referral. Upon arrival, examination revealed bluish-purple extremities, a harder texture, and cold acral areas. Pulses in the extremities were weak. Complete laboratory tests showed D-dimer >20,000 ng/mL, CRP 21.6 mg/dL. Head MRI was within normal limits. Doppler ultrasound of the extremities did not reveal thrombosis in the leg veins, and echocardiography also did not show the presence of thrombus. The patient was treated with antibiotics and anticoagulants for 10 days. During hospitalization, the patient showed clinical and laboratory improvement. Discussion: Acute limb ischemia in pediatric patients is uncommon, typically associated with trauma or iatrogenic factors. In this pediatric case, the etiology of acute limb ischemia (ALI) remained unclear, as no embolic source or thrombotic occlusion was detected on Doppler ultrasound or echocardiography. This highlights the limitation of the initial diagnostic work-up, since advanced imaging such as CT angiography would be required to further delineate potential underlying vascular abnormalities or occult causes that might not be evident on standard modalities. |

| Abstrak | : | Synovial sarcoma, a rare tumor primarily afecting the lower extremities, often requires surgical excision to ensure tumor removal and limb preservation. This case highlights the importance of reconstructive options in achieving optimal functional and aesthetic outcomes for patients with large surgical defects. Case: A 51-year-old female with left foot synovial sarcoma (T2N0M0) underwent Chopart amputation to achieve clear surgical margins. The resulting defect was extensive, involving both skin and deeper soft tissues, making primary closure impossible. Reconstruction was performed using the Superfcial Circumfex Iliac Perforator (SCIP) free fap harvested from the groin region, which provided robust soft tissue coverage and minimized donor site morbidity. The patient’s postoperative course was uneventful, with no complications such as fap necrosis or infection. Early rehabilitation was initiated to restore limb function, and long-term follow-up showed no evidence of recurrence or functional impairment. Conclusion: Chopart amputation with SCIP fap is an efective option for foot synovial sarcoma management, ensuring both tumor clearance and limb function preservation.This case demonstrates the value of microsurgical reconstruction in complex oncologic cases and underscores the importance of multidisciplinary care in achieving favorable outcomes. |

| Abstrak | : | Nerve reconstruction is an essential procedure in the management of nerve damage. When end-to-end primary repair is not possible, an autologous nerve graft is the gold standard for management. The sural nerve is considered the most reliable harvest site. Compared to other reconstructive options, auto graft provides the best similar physiologic nerve environment for axonal regeneration. To achieve an efective neural regeneration, tension-free repair sites should be provided, as they hinder focal neural ischemia caused by disrupted microvascular fow. Case: A 52-year-old woman with a giant schwannoma of the ulnar nerve had a tumor excision surgery followed by sural nerve grafting in a low-resource setting where microsurgery equipment is unavailable. Maluku, with archipelago-type geography, poses signifcant challenges to healthcare professionals in performing guideline-based procedures. Conclusion: Considering the unavoidable risk of nerve damage and signifcant gap, tumor excision followed by nerve reconstruction using autograft was chosen in this case, resulting in a decent outcome. |

| Abstrak | : | Chronic obstructive pulmonary disease (COPD) is a lung disease with chronic respiratory symptoms and exacerbations that can be prevented and treated. COPD is characterized by airfow obstruction that is not fully reversible, generally due to long-term exposure to cigarette smoke, pollution, or other environmental risk factors. Multiaspect COPD assessment after confrmation of COPD diagnosis is needed to guide treatment. The diagnosis is established by spirometry and clinical evaluation, including assessment of symptoms, history of exacerbations, blood eosinophil levels, and the presence of comorbidities. COPD pharmacotherapy aims to reduce symptoms, reduce the risk of exacerbations, and improve the patient’s quality of life. Pharmacotherapy is administered during stable conditions or during exacerbations using bronchodilators alone or in combination, corticosteroids, and other supportive medications according to the patient’s needs, abilities, and condition. Personalized therapy based on symptom severity, history of exacerbations, and patient response. Regular monitoring, proper inhaler technique, and treatment adherence are essential for achieving optimal |

| Abstrak | : | Last month we looked at total enrollments in physics in U.S. high schools. These data come from our survey of high school physics. We reach out to a nationally representative sample of public and private high schools and the teachers who are teaching physics there. Our most recent survey was conducted during the 2018–19 academic year. We label the survey using the spring semester. As noted, we ask about the types of physics classes the school is offering. AP Physics B was offered for the last time during the 2013 academic year; AP Physics 1 and 2 were first taught in the 2014 academic year. The figure below shows the proportion of total students enrolled by the various types of physics classes offered. The blue shades indicate students enrolled in Physics First and Conceptual Physics. The orange shades indicate those enrolled in Regular Physics, with the lighter orange indicating students... |

| Abstrak | : | The refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on the other hand, indicates how the RI depends on the wavelength and is central in, e.g., optical communication systems. Chromatic dispersion also plays an important role when teaching optics due to the captivating natural phenomenon of the rainbow and the white light decomposition with a prism. In this work, we propose and explore a method to characterize the refractive index of transparent liquids in the visible range without any dedicated equipment or device (such as prisms, goniometer, laser, detector, etc.). |

| Abstrak | : | The statics of fluids may seem simple at first but often poses problems for students when it comes to applying it to concrete cases. Despite its relatively simple laws, some subtleties, mainly related to the elastic characteristics of a fluid, must be noted. This elasticity allows the pressure exerted in a part of the fluid to propagate in its entirety, a non-intuitive concept for students as they consider more readily solid objects. |
