Presented are guidelines for the prevention, diagnosis, and treatment of cow's milk protein allergy (CMPA) which is the most common food allergy in infants. It manifests through a variety of symptoms that place a burden on both the infant and their caregivers. The guidelines were formulated by evaluation of existing evidence-based guidelines, literature evidence and expert clinical experience. The guidelines set out practical recommendations and include algorithms for the prevention and treatment of CMPA. For infants at risk of allergy, appropriate prevention diets are suggested. Breastfeeding is the best method for prevention; however, a partially hydrolyzed formula should be used in infants unable to be breastfed. In infants with suspected CMPA, guidelines are presented for the appropriate diagnostic workup and subsequent appropriate elimination diet for treatment. Exclusive breastfeeding and maternal dietary allergen avoidance are the best treatment. In infants not exclusively breastfed, an extensively hydrolyzed formula should be used with amino acid formula recommended if the symptoms are life-threatening or do not resolve after extensively hydrolyzed formula. Adherence to these guidelines should assist healthcare practitioners in optimizing their approach to the management of CMPA and decrease the burden on infants and their caregivers.

The World Health Organization (WHO) declared the outbreak of H1N1 pandemic in 2009. South Korea also had outbreaks of H1N1 virus and used oseltamivir in large volume with increased reports of adverse drug reaction(ADR). The present study was aimed to investigate the ADR frequency, the factors related to ADR, and characteristics of oseltamivir's ADR. Participants for the study were patients randomly drawn from those who were prescribed oseltamivir for treatment from CHA Bundang Medical Center during October 1 and October 30. The information examined as factors related to ADR were collected by a subsequent cross-sectional telephone survey. The factors are the following; a) age; b) gender; c) patient medical history; d) diagnosis of H1N1 virus; e) adherence; f) whether taking other medication with oseltamivir or not; and g) the number of combined medications. We also asked ADR after taking oseltamivir. Total subjects were 86 patients. The average age is $22.6{\pm}18.48$ years old. The gender was 45.3% women and 54.7% men. Half (50%) of all respondents showed one or more ADR, 67.4% were positively diagnosed for H1N1 virus, and 54.7% were completed the full course of oseltamivir (i.e. twice daily x 5days). The most frequently reported ADR symptoms were: dizziness (15.1%), nausea (11.6%), lethargy (10.4%), diarrhea (10.4%), abdominal pain (8.1%), headache and vomiting (6.9%). ADR classifications by categories are gastro intestinal (44.2%), neuropsychiatric events (22.1%), systemic symptom (20.9%), skin events (5.8%), eye events (4.7%), and other cases (2.3%). The onset of ADR 'after taking 1~3 doses' was 69.7%. No increase in neuropsychiatric events was detected in children and adolescents. No factors examined for the study do have significant influence on the presence of ADR. This study showed that ADR of oseltamivir have occurred in half of the patients. The use of oseltamivir is essential for treatment and prophylaxis of influenza A(H1N1). But mass treatment should be properly monitored for ADR.

Brucellosis is a contagious zoonotic disease that infects millions of people annually with hundreds of millions more being exposed. It is caused by Brucella, a highly infectious bacterial species capable of infecting humans with an estimated dose of 10-100 organisms. Sirtuin 1 (SIRT1) has been reported to contribute to prevention of viral diseases as well as a chronic infection caused by Mycobacterium bovis. Here, we investigated the role of SIRT1 in the establishment of Brucella abortus infection in both in vitro and in vivo systems using the reported SIRT1 activators resveratrol (RES), piceatannol (PIC), and ginsenoside Rg3 (Rg3). In RAW264.7 cells, SIRT1 activators did not alter the adherence of Brucella or Salmonella Typhimurium. However, reduced uptake of Brucella was observed in cells treated with PIC and Rg3, and survival of Brucella within the cells was only observed to decrease in cells that were treated with Rg3, while PIC treatment reduced the intracellular survival of Salmonella. SIRT1 treatment in mice via oral route resulted in augmented Brucella resistance for PIC and Rg3, but not RES. PIC treatment favors Th2 immune response despite reduced serum pro-inflammatory cytokine production, while Rg3-treated mice displayed high IL-12 and IFN-γ serum production. Overall, our findings encourage further investigation into the complete mechanisms of action of the different SIRT1 activators used as well as their potential benefit as an effective alternative approach against intracellular and extracellular pathogens.

Objectives This systematic review aimed to analyze the effectiveness, safety and the reporting quality of scalp acupuncture (SA) treatment for musculoskeletal disease (MSD). Methods Eleven databases were systematically searched up to July 12th 2023. Randomized controlled trials (RCTs) of SA treatment for MSD were selected manually by the inclusion criteria. The risk of bias of RCTs was assessed using the Cochrane's Risk of Bias (RoB) 1.0 and the reporting quality of studies was evaluated using Consolidated Standards of Reporting Trials (CONSORT) 2010 statement and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) 2010 checklist. Results Ten clinical studies were met the inclusion criteria. Most of studies reported SA treatment significantly alleviated pain and functional disability of MSD patients and no serious adverse effects were reported. In RoB assessment, blinding of participants and personnel was found to have the highest RoB and allocation concealment was found to have the most unclear RoB. In CONSORT 2010 statement evaluation, all studies reported 15.3 items (41.4%) on average. In STRICTA 2010 checklist evaluation, all studies reported 11.2 items (65.9%) on average. Conclusions The systematic review found that SA treatment may alleviate pain and functional disability of MSD patients and have little severe adverse effect. The reporting quality of included studies was mainly low, therefore, further studies with strict adherence to the CONSORT and STRICTA checklist should be encouraged.

미세먼지(Particulate matter, PM)는 피부 장벽의 기능을 저하시키고 염증성 피부 질환 및 외인성 노화를 유발하는 대기 오염원이다. 본 연구에서는 대체 미세먼지로서 iron oxide black을 이용하여 화장품에 의한 미세먼지의 피부 부착 방지효과를 평가하였다. 미세먼지 부유챔버는 피부노출부위, 미세먼지 주입구, 부유동력장치, 배출구로 구성하여 미세먼지가 챔버내에서 부유 중 피부에 자연스럽게 부착될 수 있도록 제작하였다. 대체 미세먼지의 부유농도에 따른 피부 밝기 변화를 확인하여 최적의 부유농도 조건을 확인하였다. Iron oxide black의 피부부착 전·후의 밝기차이 (미세먼지 부착 전 밝기 - 미세먼지 부착 후 밝기, Δ)는 미세먼지의 양에 비례한다. 또한, 화장품 5종에 대하여 각각 20명의 피험자를 대상으로 제품 도포군과 무도포 대조군으로 나누어 부유 대체 미세먼지에 대한 피부부착 방지효과를 확인하였다. 피부에 부착된 iron oxide black의 전·후 밝기 차이를 계산하여 대조군과 비교분석하였다(p < 0.05). 시험에 최소 150 mg 이상의 iron oxide black을 사용할 때 농도에 따른 피부 밝기 변화 양상이 뚜렷하게 나타났다. 최적의 부유농도에서 피부와 대체미세먼지의 밝기 간섭이 적고 피부 부착 패턴이 선명하게 나타났다. 5종의 화장품을 피부에 도포할 경우 iron oxide black의 부착양이 대조군에 비해 통계적으로 유의하게 낮았다. 이는 제품에 따라 iron oxide black의 부착을 방지 함을 의미한다. 본 연구는 대체 미세먼지로서 iron oxide black의 피부 부착양상을 확인하고, 화장품에 의한 부착 방지효과를 평가하는 안전하고 유용한 방법이다. 화장품의 다양한 제형이나 원료의 특성에 따라 미세먼지가 피부에 부착되는 것을 방지할수 있음을 확인하였다.

Background: The influence of parental socio-economic status on childhood cancer treatment outcome in low-income countries has not been sufficiently investigated. Our study examined this influence and explored parental experiences during cancer treatment of their children in an Indonesian academic hospital. Materials and Methods: Medical charts of 145 children diagnosed with cancer between 1999 and 2009 were reviewed retrospectively. From October 2011 until January 2012, 40 caretakers were interviewed using semi-structured questionnaires. Results: Of all patients, 48% abandoned treatment, 34% experienced death, 9% had progressive/relapsed disease, and 9% overall event-free survival. Prosperous patients had better treatment outcome than poor patients (P<0.0001). Odds-ratio for treatment abandonment was 3.3 (95%CI: 1.4-8.1, p=0.006) for poor versus prosperous patients. Parents often believed that their child's health was beyond doctor control and determined by luck, fate or God (55%). Causes of cancer were thought to be destiny (35%) or God's punishment (23%). Alternative treatment could (18%) or might (50%) cure cancer. Most parents (95%) would like more information about cancer and treatment. More contact with doctors was desired (98%). Income decreased during treatment (55%). Parents lost employment (48% fathers, 10% mothers), most of whom stated this loss was caused by their child's cancer (84% fathers, 100% mothers). Loss of income led to financial difficulties (63%) and debts (55%). Conclusions: Treatment abandonment was most important reason for treatment failure. Treatment outcome was determined by parental socio-economic status. Childhood cancer survival could improve if financial constraints and provision of information and guidance are better addressed.

Background: This study is to investigate the prescription patterns and factors related to the number of medications treating chronic obstructive pulmonary disease (COPD) in patients under 65 years old according to GOLD guidelines. Methods: We retrospectively analyzed the medical records of patients aged 40-64 years with a diagnosis of COPD from January to March 2016. Patients were classified by combined assessment of COPD (grades A, B, C, D) using spirometry, exacerbation history, mMRC, and/or CAT results. We analyzed prescribed medications, treatment options and factors related to the numbers of COPD medications. Results: The total number of prescriptions were 251. About 35.5% of patients were classified as GOLD A, 34.2% as GOLD B, 17.1% as GOLD C and 13.2% as GOLD D. Inhaled bronchodilator was prescribed for 86.9% of patients and the most frequent COPD medication was long-acting muscarinic antagonist (LAMA) followed by inhaled corticosteroids/long acting beta agonist (ICS/LABA). The majority of low risk patients (GOLD A/B) were prescribed a monotherapy with LAMA or LABA. For high risk patients (GOLD C/D), combination treatment with ICS+LAMA+LABA was mostly prescribed. The 21.2% of patients in GOLD D received systemic corticosteroid. The average number of medications per prescription was 3.7, and this number increased with increasing COPD grade, COPD duration and lung function reduction ($FEV_1$, $FEV_1/FVC$). Conclusion: Generally high adherence to GOLD guideline recommendations was reported. Given the progressive nature of the disease, results suggest that closer attention to respiratory symptoms for early detection, diagnosis, and appropriate treatment of COPD is warranted.

Long term outcomes after liver transplantation are major determinants of quality of life and of the value of this heroic treatment. As short term outcomes are excellent, our community is turning to take a harder look at long term outcomes. The purpose of this paper is to review these outcomes, and highlight proposed treatments, as well as pressing topics needing to be studied. A systemic review of the English literature was carried in PubMed, covering all papers addressing long term outcomes in pediatric liver transplant from 2000-2013. Late outcomes after pediatric liver transplant affect the liver graft in the form of chronic liver dysfunction. The causes include rejection particularly humoral rejection, but also de novo autoimmune hepatitis, and recurrent disease. The metabolic syndrome is a major factor in long term cardiovascular complication risk. Secondary infections, kidney dysfunction and malignancy remain a reality of those patients. There is growing evidence of late cognitive and executive function delays affecting daily life productivity as well as likely adherence. Finally, despite a good health status, quality of life measures are comparable to those of children with chronic diseases. Long term outcomes are the new frontier in pediatric liver transplantation. Much is needed to improve graft survival, but also to avoid systemic morbidities from long term immunosuppression. Quality of life is a new inclusive measure that will require interventions and innovative approaches respectful not only on the patients but also of their social circle.
