To halt the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), governments around the world have imposed policies, such as lockdowns, mandatory mask wearing, and social distancing. The application of disinfecting materials in shared public facilities can be an additional measure to control the spread of the virus. Copper is a prominent material with antibacterial and antiviral effects. In this study, we synthesized copper nanoparticles (CuNPs) as a surface coating agent and assessed their antiviral activity against SARS-CoV-2. CuNPs with a mean size of 254 nm in diameter were synthesized from copper sulfate as a source and were predominantly composed of copper oxide. The synthesized CuNPs were mixed with resin-based paint (CuNP/paint) and sprayed on the surface of stainless steel remnants. SARS-CoV-2 lost 97.8% infectivity on the CuNP/paint-coated surface after 30 min of exposure and more than 99.995% infectivity after 1 h of exposure. The inactivation rate was approximately 36-fold faster than that on the paint alone-coated and uncoated surfaces. The CuNP/paint-coated surface showed powerful inactivation of SARS-CoV-2 infectivity, although further study is needed to elucidate the inactivation mechanisms. Applications of CuNP/paint coatings to public or hospital facilities and other commonly touched areas are expected to be beneficial.

Patient: Female, 3 Final Diagnosis: Recurrent sarcoma botryoides Symptoms: Vaginal mass Medication: — Clinical Procedure: Surgical resection • adjuvant chemotherapy Specialty: Obstetrics and Gynecology Objective: Unusual setting of medical care Background: Sarcoma botryoides, known as embryonal rhabdomyosarcoma (ERMS), is a malignant tumor which arises from embryonic muscle cells. The incidence of ERMS in the uterine cervix rarely occurs at a very young age. With sufficient resources, management of this disease is not difficult. However, in limited resources settings, such as in Indonesia, the situation is more challenging. This case report aims to highlight the difficulties encountered in diagnosing and treating patients with sarcoma botryoides. Case Report: A 3-year-old female patient came the outpatient clinic of our hospital with a protruding mass from her vagina resembling a bunch of grapes which easily bled. She underwent surgery to remove the mass. After the procedure, she did not return to the hospital for the recommended adjuvant chemotherapy treatment due to limited funds. Three months later, she came to the outpatient clinic with the same complaint, despite smaller size. Due to limited resources, we only evaluated the metastasis using chest x-ray and did not perform intra-operative biopsy. In the second surgery, a wide excision with 1–2 cm margin was performed, followed by adjuvant chemotherapy for 6 series. We achieved a satisfactory outcome in this case, and 18 months after the surgery, the patient was still in remission. Conclusions: Sarcoma botryoides is a rare malignancy. The effective treatment for sarcoma botryoides is wide excision with safe margin of 1–2 cm, followed by 6–12 cycles of vincristine, actinomycin D, and cyclophosphamide (VAC) regiment as an adjuvant chemotherapy. A family’s understanding of the treatment plan is important to achieve desired outcomes. Even with limited resources, this malignancy can still be properly treated.

Introduction Whilst current asthma management is well-

Background Despite the reduction phenomenon of asthma

Objective To determine factors influencing forced expiratory volume in one second (FEV 1 ) reversibility in newly developed asthma in children Methods A cross sectional study was done on 52 patients aged 6-14 years who were recruited from a longitudinal study of 161 newly developed asthmatic children. Pre and post-bronchodilator FEV 1 were obtained to calculate the reversibility. Seven patients had to perform peak expiratory volume (PEV) variability before recruited. Some variables including sex, age, height, onset of asthma, frequency of asthma attacks at the time of the test were analyzed to evaluate their roles in the outcome of FEV 1 reversibility using paired sample t-test, Pearson's correlation coefficient, and multi regression analysis.Results Mean pre-and post-bronchodilator FEV 1 were 1.14 (SD 0.24) and 1.31 (SD 0.28), respectively. FEV 1 reversibility ranged between 6%-36%. Bivariate analyses demonstrated significant correlation between either cough (p=0.031) or symptom-free (p=0.041) and the airway reversibility. Multivariate analysis showed that cough was an important factor influencing airway reversibility (p=0.0246). Conclusion
