RESUMEN Objetivo: Determinar el comportamiento y evaluar las tendencias de atención médica de las enfermedades tipo influenza (ETI) dentro del sistema de salud peruano durante el periodo 2018-2022. Materiales y métodos: Estudio de tipo observacional, de diseño descriptivo y retrospectivo, el cual analizó el comportamiento de las atenciones por enfermedades tipo influenza en el Perú. Para ello se utilizó la base de datos abierta de la Superintendencia Nacional de Salud (Susalud). Las variables incluidas fueron diagnóstico CIE-10 compatible con ETI, grupos de edades, sexo, lugar y periodo de atención. El análisis estadístico se obtuvo mediante Microsoft Excel 365 y Stata v.18.0. Resultados: Durante el periodo 2018-2022, las ETI generaron, en los servicios ambulatorios, un promedio de 2 576 325 atenciones por año (rango: 1 790 821-3 710 299), las cuales representaron el 4,9 % del total de atenciones ambulatorias en el sistema de salud peruano. El 50 % de las atenciones ambulatorias por ETI se realizaron dentro de los servicios pertenecientes al Ministerio de Salud (Minsa); por su parte, el 51 % de las visitas a emergencias se realizaron en los servicios pertenecientes al Seguro Social de Salud (EsSalud). En los servicios de emergencias se registraron 1 077 584 visitas por año (rango: 312 306-1 644 758), que se codificaron según la Clasificación Internacional de Enfermedades, versión 10 (CIE-10), lo que equivalió al 15 % de todas las causas atendidas en estos servicios; mientras que en los servicios de hospitalización se reportaron 56 587 hospitalizaciones por año (rango: 46 338-67 233), las cuales representaron el 2,9 % de todas las causas de hospitalización dentro del sistema de salud del Perú. El 60,6 % de las hospitalizaciones de pacientes con ETI se realizaron en los servicios pertenecientes al Minsa. Conclusiones: En el sistema de salud peruano, cada año las ETI representan un problema frecuente que requiere de atención médica; los servicios de salud brindados por el Minsa y EsSalud son los más solicitados.

ABSTRACT Objective: To determine the behavior and healthcare trends of influenza-like illnesses (ILIs) in the Peruvian health system from 2018 to 2022. Materials and methods: An observational, descriptive, retrospective study which analyzed the behavior of healthcare visits for ILIs in Peru, using the open database of the Superintendencia Nacional de Salud (SUSALUD National Superintendency of Health). The variables included diagnoses compatible with ILIs according to the International Classification of Diseases, 10th Revision (ICD-10), age groups, sex, location and time of care. The statistical analysis was performed using Microsoft Excel 365 and Stata 18. Results: Between 2018 and 2022, ILIs generated an average of 2,576,325 outpatient visits per year (range: 1,790,821-3,710,299), which accounted for 4.9 % of all outpatient visits in the Peruvian health system. Fifty percent of outpatient visits for ILIs occurred at the Ministry of Health (MINSA) services; in contrast, 51 % of emergency visits for ILIs occurred at the Seguro Social de Salud (EsSalud Social Security Health Insurance) services. Emergency services recorded 1,077,584 visits annually (range: 312,306-1,644,758), coded according to ICD-10, which accounted for 15 % of all causes treated in these services. Meanwhile, hospitalization services reported 56,587 hospitalizations per year (range: 46,338-67,233), representing 2.9 % of all hospitalizations in the Peruvian health system, where 60.6 % of ILI-related hospitalizations were in MINSA's services. Conclusions: In the Peruvian health system, ILIs pose a recurrent healthcare problem each year, with the health services of MINSA and EsSalud being the most in demand.

An ambispective observational study on antibiotics in pulmonology department in a tertiary care hospital

Background: Respiratory tract infections (RTIs) caused by various viruses and bacteria are a major cause of morbidity and mortality worldwide. Although they are usually more severe in children, the elderly and people with weakened immune systems, people of all ages and backgrounds are susceptible to these infections. Antibiotics are commonly prescribed for RTIs in primary care in adults and children. The main purpose of this study is to monitor the use of different antibiotics for respiratory infections. Methods: It is an ambispective observational study, during which data are collected on specially designed data collection forms. The study lasted 6 months (from December 2022 to May 2023). Results: The source of data is a total of 100 patients who were prescribed at least one dose of antibiotics. Out of 100 people, 53% were men and 47% were women. LRTI and URTI are the most common conditions for which antibiotics are prescribed, and we found that the most commonly prescribed antibiotics are a higher percentage of patients using cephalosporins. Of the various cephalosporins, the most commonly prescribed is ceftriaxone, a third-generation cephalosporin. Conclusions: From this particular observational study, we concluded that the most frequently prescribed antibiotics for respiratory infections were cephalosporins, ceftriaxone, third-generation cephalosporins were most frequently prescribed, followed by macrolides, penicillin, tetracyclines, lincomycin, fluoroquinolones, oxazolidinones. The use of antibiotics helps to improve patient care by reducing side effects such as antibiotic resistance, hypersensitivity reactions, respiratory difficulties and risks associated with respiratory infections.

Manifestaciones clínicas y radiológicas de la Aspergilosis Pulmonar: Informe de tres casos / Pulmonary aspergillosis, an approach to clinical and radiological manifestations. Report of three cases

RESUMEN La aspergilosis pulmonar, causada por el hongo oportunista Aspergillus, afecta principalmente a individuos inmunocomprometidos. Este reporte presenta tres casos: Una mujer de 18 años con leucemia aguda desarrolló dificultad respiratoria y patrones bilaterales de "árbol en brote" en la tomografía computarizada (TC). A pesar del tratamiento con voriconazol, falleció debido a insuficiencia respiratoria. Una mujer de 58 años con diabetes y EPOC presentó disnea y hemoptisis. Las imágenes revelaron una lesión cavitada, confirmando un aspergiloma. Se consideró la cirugía debido a la hemoptisis activa. Una mujer de 41 años con antecedentes de tuberculosis presentó fiebre y síntomas respiratorios. La TC mostró lesiones cavitadas y bronquiectasias, confirmando aspergilosis crónica. Respondió bien al voriconazol. Estos casos destacan la variabilidad en la aspergilosis pulmonar y subrayan la importancia de un diagnóstico y tratamiento oportunos para mejorar los resultados en los pacientes.

ABSTRACT Pulmonary aspergillosis, caused by the opportunistic fungus Aspergillus, primarily affects immunocompromised individuals. This report presents three cases: An 18-year-old female with acute leukemia developed respiratory distress and bilateral "tree-in-bud" patterns on CT. Despite voriconazole treatment, she succumbed to respiratory failure. A 58-year-old female with diabetes and COPD had dyspnea and hemoptysis. Imaging revealed a cavitated lesion, confirming aspergilloma. Surgery was considered due to active hemoptysis. A 41-year-old female with a history of tuberculosis presented with fever and respiratory symptoms. CT showed cavitated lesions and bronchiectasis, confirming chronic aspergillosis. She responded well to voriconazole. These cases highlight the variability in pulmonary aspergillosis and underscore the importance of timely diagnosis and treatment to improve patient outcomes.

Current clinical profiles of acute respiratory tract infections in children between 2 months to 5 years

Background: The nascent respiratory tract of infants is highly vulnerable to frequent infections, thereby making acute respiratory infections a major risk factor for under five years morbidity and mortality. The clinical presentation of acute respiratory tract infections (ARTI) is however ambiguous and varied depending on a plethora of factors. The aim was to delineate the respiratory disease profiles of children aged 2 months-5 years in Western Maharashtra.Methods: The present cross sectional analytical study was conducted on 249 children aged between 2 months-5 years consulting the Pediatric wards and OPD with complaints of fever with cough, cold, breathlessness, and chest pain. A comprehensive medical history was procured, followed by general and systemic examinations. Infections were assessed and x-ray was taken for all the patients. Data was analyzed using statistical software R version 4.0.3 and Microsoft Excel.Results: The male:female ratio in the study was 137:112. Cold (80.72%) and cough (74.3%) were the most widely experienced symptoms among patients, while chest pain (0.8%) was the least common. Among 249 cases, upper respiratory tract infection (URTI; 60%) was more predominantly noted than lower respiratory tract infections (LRTI; 44.8%). Nasopharyngitis (34.14%) and tonsillopharyngitis (6.83%) were the commonly prevalent types of URTI whereas pneumonia and bronchiolitis were the most recurrent types in the LRTI.Conclusions: Practitioners must consider the possibility of acute URTI more closely and must not be quick to disregard common symptoms such as cold and cough. Misdiagnosis or delayed diagnosis can severely hamper the prognosis of ARTI in young children. Hence, keeping abreast of the current clinical profiles exhibited by ARTI is of paramount importance for practitioners and the general population in the fight against under 5 mortalities.

Assessment of KaraShieldTM properties in supporting the immune health of healthy subjects: a randomized, parallel, double-blind, placebo-controlled clinical study

Background: This study aims to investigate whether a novel herbal extract blend, KaraShieldTM could be used to help build a healthy immune system that could reduce the number of incidences or severity of common upper respiratory tract infections (URTIs). Methods: A randomized, parallel, double-blind, placebo-controlled clinical study of 60 days was done on 120 healthy subjects allocated to a treatment arm (500 mg/day, KaraShieldTM) or placebo arm (500 mg/day). Results: A 500 mg daily dosage of KaraShieldTM significantly improved the subjects' immune health as measured by parameters such as the frequency and severity of upper respiratory tract conditions, the serum IgG level, mean ISQ raw score, WURSS scale score, CRP level in the serum and WHOQOL-BREF score at the end of the study period of sixty days from the baseline compared to that of the placebo. The investigated product was found to be safe and well tolerated by the subjects. Conclusions: KaraShieldTM may represent a promising safe and effective formulation for building a healthy immune system that could then counteract URTIs.

Study of association of respiratory viruses in the etiology of acute lower respiratory tract infections in children and correlation with clinical and laboratory features: role of emerging new viruses

Background: Viruses are one of the major causes of childhood pneumonia with the respiratory syncytial virus getting great attention as an important organism for pneumonia. Methods: This cross-sectional study was conducted in the Department of Paediatrics, Sree Gokulam Medical College and Research Foundation, Thiruvananthapuram, Kerala from May 2022 TO November 2022. 119 children admitted with lower respiratory tract infections were included in this study. Symptoms, signs, and investigation reports including PCR and clinical course in the hospital were recorded. Results: 25% of children were in the age group less than 1 year, 52% were between 1-5 years and 23% were above 5 years. Viruses were isolated in 82 patients (68.9%). The main viruses were respiratory syncytial virus (23.5%), boca virus (16.14%), influenza A (7.5%), influenza B (4.2%), meta pneumonia virus (3.3%), and para influenza virus (2.5%). Patients with boca virus infections had a more severe clinical course. Conclusions: Molecular testing with PCR along with clinical and lab parameters will help us to have more insights into the etiology and clinical presentation of respiratory infections in children and help us to do optimum management avoiding unnecessary antibiotic usage.

Effect of Atractylenolide Ⅰ on Lung Injury in Rats with Recurrent Respiratory Tract Infection of Lung and Spleen Qi Deficiency by Regulating the PI3K/Akt/mTOR Signaling Pathway / 中药新药与临床药理

Objective To investigate the effect of atractylenolideⅠon lung injury in rats with recurrent respiratory tract infection(RRTI)of lung and spleen qi deficiency by regulating phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR)pathway.Methods Eighty-four rats were randomly separated into a control group,a model group,a low-dose atractylenolideⅠgroup,a high-dose atractylenolideⅠgroup,a positive drug group,an insulin-like growth factor-1(IGF-1)group,and a high-dose atractylenolide Ⅰ+IGF-1 group,with 12 rats in each group.Except for the control group,the RRTI rat model of lung and spleen qi deficiency was constructed using a combination of fatigue,dietary disorders,and fumigation method with shavings and tobacco among rats in other groups.After the model is successfully copied,the model was administered once a day for 6 weeks.Animal lung function instrument was applied to detect the changes of peak expiratory flow(PEF),forced expiratory volume in first second(FEV1),forced vital capacity(FVC)in rats.The changes of wet/dry mass ratio of lungs in rats were detected.HE staining was applied to detect pathological changes of lung tissue in rats of each group.ELISA was applied to detect the levels of interleukin(IL)-6,tumor necrosis factor-α(TNF-α),malondialdehyde(MDA)and the activity of superoxide dismutase(SOD)in rat lung tissue.Western Blot was applied to determine the protein expressions of p-PI3K,p-Akt,and p-mTOR in rat lung tissue.Results Compared with the control group,rats in the model group showed a decrease in PEF,FEV1 and FVC(P＜0.01)and an increase in the wet/dry mass ratio of lungs(P＜0.01).The alveolar septa in lung tissues had become larger.Pulmonary interstitial edema and a large amount of inflammatory cell infiltration were found.The levels of IL-6,TNF-α and MDA in lung tissue increased(P＜0.01),and the SOD activity decreased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue increased(P＜0.01).Compared with the model group,rats in the low-,high-dose atractylenolideⅠgroups,and positive drug group showed an increase in PEF,FEV1,and FVC,and a decrease in the wet/dry mass ratio of lungs(P＜0.01).Pathologic damage in lung tissue was alleviated.The levels of IL-6,TNF-α,MDA decreased and SOD activity in lung tissue increased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue decreased(P＜0.01),while the corresponding indicators in the IGF-1 group showed opposite trends(P＜0.01).Compared with the high-dose group of atractylenolide I,rats in the high-dose atractylenolide I+IGF-1 group showed a decrease in PEF,FEV1 and FVC,and an increase in the wet/dry mass ratio of lungs(P＜0.01).Pathologic damage in lung tissue was increased.The levels of IL-6,TNF-α,MDA increased and the SOD activity in lung tissue decreased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue increased(P＜0.05,P＜0.01).Conclusion AtractylenolideⅠmay improve lung injury in RRTI rats of lung and spleen qi deficiency by inhibiting the PI3K/Akt/mTOR pathway.

Effect of an extracorporeal diaphragm pacemaker combined with airway clearance technology on pulmonary infection, diaphragmatic mobility and thickness in older adult patients with dementia / 中国基层医药

Objective:To investigate the efficacy of an extracorporeal diaphragm pacemaker (EDP) combined with airway clearance technology (ACT) in the treatment of pulmonary infection in older adult patients with dementia and its impact on diaphragmatic mobility and thickness.Methods:A total of 60 patients with dementia and pulmonary infections who received treatment at The Second Hospital of Jinhua from June 2022 to February 2023 were included in this prospective study. These patients were randomly divided into an observation group and a control group, with 30 patients in each group. The control group received ACT treatment, while the observation group received EDP treatment on the basis of ACT treatment. Two groups were treated for 4 successive weeks. Efficacy was compared between the two groups. Before and after treatment, sputum color score, sputum quality score, diaphragmatic mobility, and diaphragmatic thickness were compared between the two groups.Results:The overall response rate in the observation group was 93.33% (28/30), which was significantly higher than 73.33% (22/30) in the control group ( Z = 2.08, P = 0.038). After treatment, the sputum color score, sputum quality score, and sputum volume in the observation group were (0.46 ± 0.12) points, (0.34 ± 0.10) points, and (8.47 ± 1.23) mL, respectively, which were significantly lower than (0.89 ± 0.17) points, (0.76 ± 0.18) points, and (13.25 ± 2.87) mL, respectively, in the control group ( t = 11.32, 11.17, 8.38, all P < 0.001). After treatment, the diaphragmatic mobility and thickness in the observation group were (13.52 ± 0.51) mm and (0.52 ± 0.06) mm, respectively, which were significantly greater than (12.76 ± 0.41) mm and (0.44 ± 0.04) mm, respectively, in the control group ( t = -6.36, -6.08, both P < 0.001). Conclusion:The combined application of EDP and ACT shows a significant therapeutic effect on patients with dementia and pulmonary infection, effectively improving their pulmonary function, increasing the mobility and thickness of the diaphragm, and alleviating difficulties in breathing.

Letter to the Editor: Pathogens detected from patients with acute respiratory infections negative for SARS-CoV-2, Saitama, Japan, 2020

@#Utilizing data presented in the article by Miyashita et al., we illustrate the importance of testing data when assessing surveillance data. Accounting for the number of tests (denominator) and positivity (proportion of tests positive for a specific pathogen(s)) improves data interpretation in ways not possible from numerator case data alone.

The relationship between the expression of TLR2 and TLR4 in peripheral blood mononuclear cells and Th1/Th2 immune response in children with recurrent respiratory tract infection / 国际检验医学杂志

Objective To investigate the expression of Toll-like receptor 2(TLR2)and Toll-like receptor 4(TLR4)in peripheral blood mononuclear cells(PBMC)in children with recurrent respiratory tract infection(RRTI)and its relationship with T helper cell 1(Th1)/T helper cell 2(Th2)immune response.Methods A total of 65 children diagnosed with RRTI who admitted to the hospital from December 2020 to December 2022 were enrolled in the study as the RRTI group,and 45 healthy children who underwent physical examination in the hospital during the same period were enrolled as the control group.The relative expression levels of TLR2 and TLR4 mRNA in PBMCs were detected by real-time fluorescence quantitative PCR(qPCR).The expres-sion rates of TLR2 and TLR4 protein in PBMCs were detected by flow cytometry.The levels of Th1 cytokine interferon-γ(IFN-γ),Th2 cytokine interleukin-4(IL-4)and their ratio(IFN-γ/IL-4)in plasma were detected by enzyme-linked immunosorbent assay(ELISA).Pearson correlation analysis was used to analyze the corre-lation between TLR2,TLR4 protein expression rates and plasma IFN-γ,IL-4 levels.Results The RRTI group had significantly higher plasma level of Th2 cytokine IL-4 than the control group,significantly lower plasma level of Th1 cytokine IFN-y than the control group,and significantly lower ratio of IFN-γ/IL-4 than the con-trol group,the differences were all statistically significant(P＜0.05).The relative expression levels of TLR2 and TLR4 mRNA and protein expression rates in PBMC of children in the RRTI group were higher than those in the control group,and the differences were statistically significant(P＜0.05).Pearson correlation analysis showed that the protein expression rates of TLR2 and TLR4 in PBMC of children with RRTI were both nega-tively correlated with both plasma IFN-γ levels and IFN-γ/IL-4(P＜0.05)and positively correlated with plasma IL-4 levels(P＜0.05).Conclusion The expression of TLR2 and TLR4 in PBMC and plasma Th1/Th2 cytokines in children with RRTI may be involved in the occurrence and development of the disease.Ex-cessive activation of TLR2 and TLR4 may weaken Th1 function and enhance Th2 function.

Multidrug stewardship and adherence to guidelines in >200,000 direct-to-consumer Telemedicine encounters

ABSTRACT Objective: The quality of care and safety for Telemedicine-discharged patients with suspected respiratory infections are closely related to low rates of prescriptions of unjustified and high-risk medications. This retrospective study aimed to assess adherence to the current COVID-19 guidelines in direct-to-consumer telemedicine encounters at a large center using multidrug stewardship protocols. Methods: A quarterly electronic survey utilizing medical records of individual physician care assessed various quality indicators. Physicians received ongoing adaptive feedback based on personal metrics, with Telemedicine Center recommendations derived from the 2020 Infectious Diseases Society of America guidelines. The study included all consecutive adults with new respiratory symptoms in the last 14 days who sought spontaneous Telemedicine consultations between March 2020 and August 2021. This study analyzed patients with suspected or confirmed COVID-19 and other airway infections. Results: Of the 221,128 evaluated patients, 42,042 (19%) had confirmed COVID-19; 104,021 (47%) were suspected to have COVID-19; and, 75,065 (33%) had other diagnoses. Patients with suspected or confirmed COVID-19 had a mean (+DP) age of 35±12 years. A total of 125,107 (85.65%) patients were managed at home, 2,552 (1.74%) were referred for non-urgent in-office reassessment, and 17,185 (11.7%) were referred to the emergency department for whom there was no further treatment recommendation. The antibiotic rate in confirmed or suspected COVID-19 cases was 0.46%/0.65% and that for non-evidence-based prescriptions was 0.01%/0.005%. Conclusion: Guideline training and Telemedicine consultation feedback may lead to lower antibiotic and antimicrobial prescriptions in suspected and confirmed COVID-19 cases. Multidrug stewardship protocols may improve guideline adherence and reinforce the quality of care and safety in Telemedicine encounters.

Association between teenage mothers and acute infections in children under five in Peru from 2015-2019 / Asociación entre madres adolescentes e infecciones agudas en menores de cinco años en el Perú 2015-2019

Abstract Objectives: to assess the association between mothers age and the presence of acute respiratory infections (ARIs) and acute diarrhea (AD) in Peruvian children under five years old. Methods: secondary analysis of the database of the "Demographic and Family Health Survey" of 2015 and 2019. We analyzed data from children under five and their reproductive-age mothers who live in the same household. Poisson regression models were used to generate adjusted prevalence ratios (aPR) with 95% confidence intervals (95%CI) to assess the association between mothers' age group and the presence of ARIs and AD in their children. Results: 84,671 mother/child data were analyzed. In the adjusted regression model, being a young mother (aPR= 1.18; 95%CI= 1.11-1.25; p<0.001) or an teenage (aPR= 1.11; 95%CI= 1.01-1.22; p=0.045) were associated with a higher prevalence of ARIs in their children. In addition, being a young mother a teenage (aPR= 1.18; 95%CI= 1.11-1.25; p<0.001) or a teenage (aPR= 1.22; 95%CI= 1.10-1.35; p<0.001) were also associated with a higher prevalence of AD cases in their children. Conclusions: mothers' age was found to be associated with the prevalence of ARIs and AD in Peruvian children under five, with teenagers and young mothers having the greatest probability of ARIs and AD.

Resumen Objetivos: evaluar la asociación entre la edad materna y la presencia de infecciones respiratorias agudas (IRAs) y enfermedades diarreicas agudas (EDAs) en niños peruanos menores de cinco años. Métodos: análisis secundario de la base de datos de la "Encuesta Demográfica y de Salud Familiar" de 2015 y 2019. Se analizaron datos de niños menores de cinco años y sus madres en edad reproductiva que viven en el mismo hogar. Se utilizaron modelos de regresión de Poisson para calcular razones de prevalencia ajustadas (RPa) con sus intervalos de confianza del 95% (IC95%) para evaluar la asociación entre el grupo de edad de las madres y la presencia de IRAs y EDAs en sus hijos. Resultados: se analizaron 84,671 datos madre/hijo. En el modelo de regresión ajustado, ser madre joven (RPa= 1,18; IC95%= 1,11-1,25; p<0,001) o adolescente (RPa= 1,11; IC95%= 1,01-1,22; p=0,045) se asoció con una mayor prevalencia de IRAs en sus hijos. Además, ser madre joven (RPa= 1,18; IC95%= 1,11-1,25; p<0,001) o adolescente RPa= 1,22; IC95%= 1,10-1,35; p<0,001 también se asoció con una mayor prevalencia de EDAs en sus hijos. Conclusiones: la edad de las madres se asoció con la prevalencia de IRAs y EDAs en niños peruanos menores de cinco años, siendo las madres adolescentes y jóvenes las que presentaron mayor probabilidad de IRAs y EDAs.

Infectious disease evaluations in a psychiatric unit, an observational study / Visitas infectológicas a una unidad psiquiátrica, un estudio observacional

Patients in adult psychiatric wards present infectious complications or pathologies that mimic an infectious condition, and there is little information on this subject. OBJECTIVES: To know the frequency and infectious and non-infectious complications treated by infectious disease specialists in a psychiatric intensive-care hospitalization unit for adults and their outcomes. METHODS: Observational study between 2016 and 2021. RESULTS: 37 patients with 41 events were evaluated. Almost half of the visits to these events originated from an antimicrobial stewardship program (46.3%). In 68.3% of the events, complementary studies were requested; in 14.6%, referral to other specialties; in 26.8%, an antimicrobial treatment was started; and in 75%, modifications were made to previous schemes. An infectious cause was identified in 30 of 41 events (73.2%) that included the following conditions: respiratory (31.7%), skin (9.8%), urinary (7.3%), gynecological (2.4%), one case of bacteremia with unknown source (2.4%), sequential infections (4.9%) and HIV therapy dropouts (7.3%). In the 11 remaining events, non-infectious causes were identified (26.8%): pulmonary thromboembolism, drug hepatotoxicity, false positive VDRL and HIV tests, steroid-induced psychosis in an HIV patient with thrombocytopenia, fever without etiology, residual positive SARS-CoV-2 PCR test, low O2 pulse oximetry due to oversedation and neuroleptic malignant syndrome. There was no mortality. CONCLUSIONS: Patients in psychiatric hospitalization wards suffer from a great diversity of infectious problems during their stay with conditions that simulate infections. An antibiotic surveillance system can detect half of these conditions. The infectious diseases visits allow for advising or reorienting of the study and modifying the antibiotic treatment.

Los pacientes en salas de hospitalización psiquiátricas de adultos presentan complicaciones infecciosas o patologías que simulan un cuadro infeccioso y existe escasa información sobre este tema. OBJETIVOS: Conocer la frecuencia y tipo de complicaciones infecciosas y no infecciosas atendidas por especialistas de infectología en un Servicio de hospitalización psiquiátrica de cuidados intensivos de adultos y sus desenlaces. MÉTODOS: Estudio observacional entre el 2016 y 2021. RESULTADOS: Se visitaron 37 paciente con 41 eventos. Casi la mitad de las visitas en estos eventos se originó por seguimiento de antimicrobianos (46,3%). En el 68,3% de los eventos se solicitaron estudios complementarios, en 14,6% la opinión de otras especialidades, en 26,8% se inició un tratamiento antimicrobiano y en 75% se hicieron modificaciones a esquemas previos. En 30 de 41 eventos se identificó una causa infecciosa (73,2%) que incluyeron las siguientes condiciones: respiratorias (31,7%), cutáneas (9,8%), urinarias (7,3%), ginecológicas (2,4%), bacteremia sin foco (2,4%), infecciones secuenciales (4,9%) y abandonos de terapia en pacientes VIH (7,3%). En los 11 eventos restantes se identificaron causas no infecciosas (26,8%): tromboembolismo pulmonar, hepatotoxicidad por drogas, test VDRL y VIH falsos positivos, psicosis por esteroides en un paciente VIH con trombocitopenia, fiebre sin etiología, PCR SARS-CoV-2 positiva residual, desaturación de O2 por sedación y síndrome neuroléptico maligno. No hubo mortalidad en esta serie. CONCLUSIONES: Los pacientes en salas de hospitalización psiquiátrica sufren de una gran diversidad de problemas infecciosos durante su estadía junto a cuadros que simulan infecciones. Un sistema de vigilancia antibiótica permite detectar la mitad de estas condiciones. Las visitas infectológicas permiten asesorar o reorientar el estudio y modificar el tratamiento antibiótico.

El objetivo es describir la evolución de niños con fibrosis quística tratados con lumacaftor/ivacaftor. Se trata de una serie de 13 pacientes de 6 a 18 años con ≥ 6 meses de tratamiento. Se analizaron el volumen espiratorio forzado en el primer segundo (VEF1), puntaje Z del índice de masa corporal (IMC), antibioticoterapia/año, antes del tratamiento y durante 24 meses posteriores. A los 12 meses (9/13) y 24 meses (5/13), la mediana de cambio del porcentaje del predicho VEF1 (ppVEF1) fue de 0,5 pp [-2-12] y 15 pp [8,7-15,2], y del puntaje Z de IMC de 0,32 puntos [-0,2-0,5] y 1,23 puntos [0,3-1,6]. El primer año (11/13) la mediana de días de uso de antibiótico disminuyó de 57 a 28 (oral) y de 27 a 0 (intravenoso). Dos niños evidenciaron eventos adversos asociados.

Cystic fibrosis transmembrane regulator (CFTR) modulators treat defective CFTR protein. Our objective is to describe the course of children with cystic fibrosis treated with lumacaftor/ivacaftor. This is a case series of 13 patients aged 6 to 18 years with ≥ 6 months of treatment. Forced expiratory volume in the first second (FEV1), body mass index (BMI) Z-score, antibiotic therapy/year, before treatment and for 24 months after treatment were analyzed. At 12 months (9/13) and 24 months (5/13), the median change in the percent predicted FEV1 (ppFEV1) was 0.5 pp (-2­12) and 15 pp (8.7­15.2) and the BMI Z-score was 0.32 points (-0.2­0.5) and 1.23 points (0.3­1.6). In the first year, in 11/13 patients, the median number of days of antibiotic use decreased from 57 to 28 (oral) and from 27 to 0 (intravenous). Two children had associated adverse events.

Síndrome de Sweet posinfeccioso

El síndrome de Sweet es un tipo de dermatosis neutrofílica infrecuente, caracterizado por un cuadro febril agudo con aparición de lesiones en piel tipo pápulas y placas eritematosas y dolorosas, con neutrofilia periférica acompañante, que mejora con el uso de corticoides. Se presenta el caso de una paciente de 22 años, con vitíligo como enfermedad de base, que acude por un cuadro de 1 semana de evolución de sensación febril no graduada y aparición insidiosa de lesiones en piel foto expuesta. Se realizó estudios laboratoriales e histopatológicos llegando al diagnóstico de síndrome de Sweet. Con los resultados de los estudios paraclínicos se inició tratamiento con corticoides sistémicos y tópicos con excelente respuesta.

Sweet syndrome is a rare type of neutrophilic dermatosis, characterized by an acute febrile picture with the appearance of painful erythematous papules and plaques on the skin, with accompanying peripheral neutrophilia, which improves with the use of corticosteroids. The case of a 22-year-old patient, with vitiligo as the underlying disease, is presented. She attended for a 1-week history of ungraded feverish sensation and insidious appearance of lesions on photo-exposed skin. Laboratory and histopathological studies were carried out, leading to the diagnosis of Sweet syndrome. With the results of the paraclinical studies, treatment with systemic and topical corticosteroids was started with an excellent response.

Población y métodos. Se realizó un estudio descriptivo de corte transversal. Se evaluó la presencia de rinovirus y metapneumovirus por biología molecular en 163 casos negativos para panel respiratorio por técnicas de vigilancia referencial, durante todo el año 2015. Resultados. Se detectó rinovirus en el 51,5 % de los casos, metapneumovirus en el 9,8 % y coinfección rinovirus-metapneumovirus en el 6,1 %. Fueron negativos para ambos virus el 32,5 %. Conclusiones. La selección de muestras sin diagnóstico virológico permitió identificar rinovirus y metapneumovirus como agentes causales de infecciones respiratorias agudas graves pediátricas y su impacto en la morbimortalidad infantil y en nuestro sistema sanitario.

Introduction. Viruses are the main etiologic agents involved in severe acute respiratory tract infections; a viral diagnosis is not established in a high percentage of cases. Objective. To describe the frequency of rhinovirus and metapneumovirus in pediatric patients with severe acute respiratory infection and negative results for typical viruses by immunofluorescence and molecular biology at a sentinel unit of Mar del Plata. Population and methods. This was a descriptive, cross-sectional study. The presence of rhinovirus and metapneumovirus was assessed by molecular biology in 163 cases negative for respiratory panel by referral surveillance techniques throughout 2015. Results. Rhinovirus was detected in 51.5% of cases, metapneumovirus in 9.8%, and coinfection with rhinovirus and metapneumovirus in 6.1%. Results were negative for both viruses in 32.5%. Conclusions. The selection of samples without a viral diagnosis allowed us to identify rhinovirus and metapneumovirus as causative agents of severe acute respiratory infections in children and assess their impact on child morbidity and mortality and on our health care system

A study of drug utilization pattern using WHO prescribing indicators in pediatric patients

Background: The study aimed to get drug utilization pattern using WHO prescribing indicators in pediatric patients. Methods: It was an observational prospective study carried out in pediatric in-patients with a sample size of 280 patients based on inclusion, and exclusion criteria for a period of 6 months. The study data were collected using patient case record and analysis was done. Results: Out of 280 patients data collected, majority of patients were in the gender male category 168 (60%) and many were from the age group of early childhood (1-5 years) 126 (45%). Respiratory tract infections were the major diagnosis made among the sample size. The drug class commonly prescribed were oral antibiotics 261 (28.38%). The average number of drugs per prescription were 3.28%. Among the total number of prescription percentage of drugs prescribed by generic name and antibiotics were 2.7%, 76.07%. Percentage of patients prescribed with injection were 79.28%. Conclusions: This study highlights WHO prescribing core indicators in evaluating the usage of rational prescription. It helps in reinforcing rational prescribing practices and increases awareness among physicians and medical students. Irrational prescriptions may result in harmful events. A rational prescription should follow the standard treatment guidelines of WHO. The assessment of these indicators can also help us to decrease the cost burden on the patient. Continuous education with focus on rational drug usage and evidence-based medicine can further increase the understanding and improves health care policies.

Bacterial Isolates Of The Respiratory Tract Infection And Their Current Sensitivity Pattern Among Patients Admitted In Tertiary Care Hospital.

Background & Objectives: This study was aimed to observe the susceptibility pattern of bacterial isolates from respiratory tract infection (RTI). Respiratory tract infection is considered as one of the major public health problems and a leading cause of morbidity and mortality in many developing countries. Respiratory tract is the part of the human system that plays a vital role in breathing processes. In human, the respiratory system can be subdivided into an Upper respiratory tract and a Lower respiratory tract based on anatomical features. The respiratory tract is constantly exposed to microbes due to the extensive surface area. The present study was conducted retrospectively for a periodMethods: of one year November 2021 to October 2022. All respiratory specimens included Sputum, BAL, throat swab; endotracheal aspirate specimens were collected aseptically from patients and cultured on the appropriate bacteriological media (Blood agar, MacConkey agar & Chocolate Agar). Bacterial isolates were identified by biochemical tests and antimicrobial susceptibility performed by standard methods as per CLSI 2022. 152Results: (72.3%) of total 210 samples were positive for bacterial culture. 126 (82.8%) were gram negative bacilli (GNB) and 26 (17.1%) were gram positive cocci (GPC). The predominant pathogen isolated was K. pneumoniae 46 (30.2%) followed by Escherichia coli 28 (18.4%).The overall susceptibility of GNB was highest towards Imipenem, Meropenem followed by Piperacillin tazobactam and Amikacin. Gram positive organisms exhibited highest susceptibility towards Vancomycin and Linezolid. Imipenem is the most sensitive antibiotic followed by Piperacillin tazobactamConclusion: and Amikacin which can be used for empirical therapy for respiratory tract infections (RTI). The antibiotic therapy should be modified as per the culture and sensitivity report. Regular determinations of the type of bacterial pathogens and updation of antibiogram must be followed in every institution to aid in better patient management by helping the clinician in the judicious use of antibiotics.
