Objetivo: Comparar el efecto de antibióticos pediátricos sobre la microdureza superficial del esmalte dental en dientes bovinos. Métodos: Se realizó un estudio in vitro en 60 dientes bovinos no cariados. Se sumergieron 15 dientes en cada grupo de cuatro soluciones (amoxicilina, amoxicilina + ácido clavulánico, eritromicina y saliva artificial) durante 1 minuto tres veces al día durante 7 y 14 días. Se midió la microdureza de la superficie del esmalte al inicio, a los7 y 14 días de exposición a los antibióticos. Resultados: La microdureza superficial del esmalte de los dientes de los grupos de antibióticos pediátricos se redujo después de 7 y 14 días de exposición con diferencia significativa (p < 0,001), respecto a la microdureza inicial. Además, en el grupo expuesto a saliva artificial no hubo diferencia significativa (p = 0,097) en los diferentes tiempos de evaluación. Conclusiones: Se concluye que los antibióticos pediátricos afectan la microdureza del esmalte, siendo la eritromicina la que mayor disminución generó a los 14 días de exposición(AU)
Objective: To compare the effect of pediatric antibiotics on the superficial microhardness of dental enamel in bovine teeth. Methods: An in vitro study was carried out on 60 non carious bovine teeth. Fifteen teeth were immersed in each group of four solutions (amoxicillin, amoxicillin + clavulanic acid, erythromycin and artificial saliva) for 1 minute three times a day for 7 and 14 days. Enamel surface microhardness was measured at baseline, 7 and 14 days of antibiotic exposure. Results: The enamel surface microhardness of the teeth of the pediatric antibiotic groups was reduced after seven and 14 days of exposure with significant difference (p < 0.001), with respect to the initial microhardness. In addition, in the group exposed to artificial saliva there was no significant difference (p = 0.097) at the different evaluation times. Conclusions: It is concluded that pediatric antibiotics affect enamel microhardness and erythromycin generated the greatest decrease at 14 days of exposure(AU)

Resumen Objetivo: Este estudio tiene como objetivo principal determinar la respuesta al esquema de tratamiento de primera línea con triple terapia estándar (amoxicilina, claritromicina, omeprazol), para erradicación de Helicobacter pylori en una determinada población, para determinar si este esquema propuesto en guías internacionales es aún una opción adecuada para pacientes en una determinada región de Costa Rica. Métodos: Se realizó una búsqueda en el servicio de gastroenterología del Hospital San Francisco de Asís, Grecia, Alajuela, Costa Rica; de todos los pacientes con infección por Helicobacter pylori y que recibieron tratamiento de primera línea con triple terapia (amoxicilina, claritromicina y omeprazol) por 14 días, en el periodo comprendido entre febrero 2017 a febrero 2019, incluyendo para el análisis solamente en los que se contaba con una prueba confirmatoria posterior a tratamiento, ya fuera por antígeno fecal de H. pylori o biopsia convencional. Resultados: Se identificaron un total de 369 casos. El diagnóstico se realizó con biopsia en el 96,4% de los pacientes. La respuesta al tratamiento de primera línea se alcanzó en un 90.5% corroborada por antígeno fecal en el 92.1% de los casos. Conclusiones: Este estudio muestra que la terapia triple con amoxicilina, claritromicina e Inhibidor de bomba de protones por 14 días mantiene un adecuado nivel de eficacia. Sin embargo, hay que tomar en cuenta que estos datos son únicamente de un área de atracción determinada y puede que no reflejen la realidad de todo el país.
Abstract Aim: The main objective of this study is to determine the response to the firstline treatment regimen with triple standard therapy (amoxicillin, clarithromycin, omeprazole), to eradicate Helicobacter pylori in a certain population. The goal is to determine if the proposed regimen in international guidelines services is still a suitable option for patients in a certain region of Costa Rica. Methods: The study took place in San Francisco de Asís Hospital, Grecia, Alajuela, Costa Rica. All patients with a Helicobacter pylori infection that were given first- line treatment with triple therapy (amoxicillin, clarithromycin and omeprazole) for its eradication for 14 days, in the period between February of 2017 and February of 2019, were included in the study. Results: A total of 369 cases were identified. The diagnosis was made with biopsy in 96.4% of patients. Response to first-line treatment was achieved in 90.5% corroborated by fecal antigen in 92.1% of all cases. Conclusions: This study shows that triple therapy with amoxicillin, clarithromycin and omeprazole for 14 days maintains an adequate level of efficacy. However, it must be considered that these results are from a specific area and may not reflect the reality of the entire country.

Objective: To assess the efficacy and cost-effectiveness of high-dose dual therapy compared with bismuth-containing quadruple therapy for treating Helicobacter pylori(H.pylori) infection in servicemen patients. Methods: A total of 160 H. pylori-infected, treatment-naive servicemen, including 74 men and 86 women, aged from 20 years to 74 years, with a mean (SD) age of 43 (13) years, tested in the First Center of Chinese PLA General Hospital from March 2022 to May 2022 were enrolled in this open-label, randomized controlled clinical trial. Patients were randomly allocated into 2 groups: the 14-day high-dose dual therapy group and the bismuth-containing quadruple therapy group. Eradication rates, adverse events, patient compliance, and drug costs were compared between the two groups. The t-test was used for continuous variables, and the Chi-square test for categorical variables. Results: No significant difference in H. pylori eradication rates were found between high-dose dual therapy and bismuth-containing quadruple therapy by ITT, mITT and PP analysis[ITT:90.0% (95%CI 81.2%-95.6%) vs. 87.5% (95%CI 78.2%-93.8%), χ2=0.25, P=0.617;mITT:93.5% (95%CI 85.5%-97.9%) vs. 93.3% (95%CI 85.1%-97.8%), χ2<0.01, P=1.000; PP: 93.5% (95%CI 85.5%-97.9%) vs. 94.5% (95%CI 86.6%-98.5%), χ2<0.01, P=1.000 ]. The dual therapy group exhibited significantly less overall side effects compared with the quadruple therapy group [21.8% (17/78) vs. 38.5% (30/78), χ2=5.15,P=0.023]. There were no significant differences in the compliance rates between the two groups [98.7%(77/78) vs. 94.9%(74/78), χ2=0.83,P=0.363]. The cost of medications in the dual therapy was 32.0% lower compared with that in the quadruple therapy (472.10 RMB vs. 693.94 RMB). Conclusions: The dual regimen has a favorable effect on the eradication of H. pylori infection in servicemen patients. Based on the ITT analysis, the eradication rate of the dual regimen is grade B (90%, good). Additionally, it exhibited a lower incidence of adverse events, better compliance and significantly reduced cost. The dual regimen is expected to be a new choice for the first-line treatment of H. pylori infection in servicemen but needs further evaluation.

BACKGROUND@#Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens.@*METHODS@#This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables.@*RESULTS@#As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups.@*CONCLUSION@#The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.@*TRIAL REGISTRATION@#ClinicalTrials.gov, ChiCTR 1900023646.

BACKGROUND@#With the development of traditional Chinese medicine research, berberine has shown good efficacy and safety in the eradication of Helicobacter pylori (H. pylori). The present study aimed to evaluate the efficacy and safety of triple therapy containing berberine, amoxicillin, and vonoprazan for the initial treatment of H. pylori.@*METHODS@#This study was a single-center, open-label, parallel, randomized controlled clinical trial. Patients with H. pylori infection were randomly (1:1:1) assigned to receive berberine triple therapy (berberine 500 mg, amoxicillin 1000 mg, vonoprazan 20 mg, A group), vonoprazan quadruple therapy (vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, B group), or rabeprazole quadruple therapy (rabeprazole 10 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, C group). The drugs were taken twice daily for 14 days. The main outcome was the H. pylori eradication rate. The secondary outcomes were symptom improvement rate, patient compliance, and incidence of adverse events. Furthermore, factors affecting the eradication rate of H. pylori were further analyzed.@*RESULTS@#A total of 300 H. pylori-infected patients were included in this study, and 263 patients completed the study. An intention-to-treat (ITT) analysis showed that the eradication rates of H. pylori in berberine triple therapy, vonoprazan quadruple therapy, and rabeprazole quadruple therapy were 70.0% (70/100), 77.0% (77/100), and 69.0% (69/100), respectively. The per-protocol (PP) analysis showed that the eradication rates of H. pylori in these three groups were 81.4% (70/86), 86.5% (77/89), and 78.4% (69/88), respectively. Both ITT analysis and PP analysis showed that the H. pylori eradication rate did not significantly differ among the three groups (P >0.05). In addition, the symptom improvement rate, overall adverse reaction rate, and patient compliance were similar among the three groups (P >0.05).@*CONCLUSIONS@#The efficacy of berberine triple therapy for H. pylori initial treatment was comparable to that of vonoprazan quadruple therapy and rabeprazole quadruple therapy, and it was well tolerated. It could be used as one choice of H. pylori initial treatment.

Bismuth-containing quadruple therapy (BQT) has long been recommended for Helicobacter pylori ( H. pylori ) eradication in China. Meanwhile, in the latest national consensus in China, dual therapy (DT) comprising an acid suppressor and amoxicillin has also been recommended. In recent years, the eradication rate of H. pylori has reached >90% using DT, which has been used not only as a first-line treatment but also as a rescue treatment. Compared with BQT, DT has great potential for H. pylori eradication; however, it has some limitations. This review summarizes the development of DT and its application in H. pylori eradication. The H. pylori eradication rates of DT were comparable to or even higher than those of BQT or standard triple therapy, especially in the first-line treatment. The incidence of adverse events associated with DT was lower than that with other therapies. Furthermore, there were no significant differences in the effects of dual and quadruple therapies on gastrointestinal microecology. In the short term, H. pylori eradication causes certain fluctuations in the gastrointestinal microbiota; however, in the long term, the gastrointestinal microbiota eventually returns to its normal state. In the penicillin-naïve population, patients receiving DT have a high eradiation rate, better compliance, lower incidence of adverse reactions, and lower primary and secondary resistance to amoxicillin. These findings suggest the safety, efficacy, and potential of DT for H. pylori eradication.

Introduction: Third molar extraction surgery is a common dental procedure, often challenging with increased post-operative complications. The need for antibiotic prophylaxis in these cases remains debated. Objective: The aim of this study was to evaluate the effect of antibiotic prophylaxis on the postoperative clinical course of third molar extraction surgeries. Material and method: Sixty-three patients were randomly allocated into two groups after extraction of the four third molars. ATB group (N = 33) the patients received 1g of amoxicillin one hour before the surgical procedure, CTR group (N = 30) the patients did not receive antibiotic prophylaxis. Clinical analyses were performed at 3, 7, 14, and 30 days after the surgical procedure. These analyses consisted of assessing oedema, variation in mouth opening, and soft tissue healing. Furthermore, patient-centered analyses were also carried out through the application of the visual analogue scale (VAS) to assess pain, inflammation, bleeding, difficulty opening the mouth, and chewing. Result: No influence of antibiotic prophylaxis was observed on the evolution of clinical parameters of healing, oedema, and mouth opening. Patients did not notice differences regarding their comfort during the postoperative period. Conclusion: The incidence of complications observed in the present study was low and was not related to infectious processes. The use of prophylactic antibiotic therapy has no beneficial effects on the postoperative clinical course in third molar extraction.
Introdução: Exodontia de terceiro molar é um procedimento odontológico comum, frequentemente desafiador, com complicações pós-operatórias aumentadas. A necessidade de profilaxia com antibióticos nesses casos ainda é motivo de debate. Objetivo: O objetivo deste estudo foi avaliar o efeito da profilaxia com antibióticos no curso clínico pós-operatório das cirurgias de extração do terceiro molar. Material e método: Sessenta e três pacientes foram randomicamente alocados em dois grupos posteriormente a cirurgia de exodontia dos quatro terceiros molares. Grupo ATB (N = 33) utilizou 1g de amoxicilina uma hora antes do procedimento cirúrgico e grupo CTR (N = 30) sem profilaxia antibiótica. Os dentes foram classificados de acordo com Pell & Gregory e Winter. Análises clínicas foram realizadas nos períodos de 3, 7, 14 e 30 dias após o procedimento cirúrgico. As análises consistiram na avaliação do edema, variação de abertura de boca e a cicatrização dos tecidos moles. Também foram executadas análises centradas nos pacientes por meio da aplicação da escala visual analógica (VAS) para avaliação de dor, inflamação, sangramento, dificuldade de abertura bucal e de mastigação. Resultado: Não houve diferenças entre os grupos em relação ao posicionamento dos dentes. Não foi observada influência da profilaxia antibiótica nos parâmetros clínicos de cicatrização, edema e abertura de boca. Os pacientes não notaram diferenças em relação ao seu conforto no pós-operatório. Conclusão: A incidência de complicações foi baixa e não foi relacionada a processos infecciosos. O uso de antibioticoterapia profilática não apresentou efeitos benéficos para o curso clínico pós-operatório em exodontia de terceiros molares.

Introducción: Las infecciones representan la etiología más frecuente del síndrome febril prolongado (SFP). Si bien las fiebres entéricas constituyen una causa posible, en Uruguay su prevalencia ha disminuido significativamente con la mejora de las condiciones socio sanitarias. Objetivo: Comunicar el caso de un adolescente con una etiología actualmente excepcional de SFP. Caso clínico 14 años, sano, zona suburbana. Comienza 2 semanas previo al ingreso con dolor en hemiabdomen superior. Agrega cefalea holocraneana leve y vómitos ocasionales. 5 días previos al ingreso fiebre 40°C axilar, un pico diario, sin otra sintomatología. Tránsito digestivo bajo y urinario normal. Examen físico: lúcido, buen aspecto general, abdomen doloroso a la palpación profunda en epigastrio. Sin irritación peritoneal. Resto normal. Analítica: Leucocitos 5200mm3, Proteína C reactiva 71.4mg/dL, hemocultivo sin desarrollo. Ecografía abdominal, radiografía de tórax y ecocardiograma normales. Serologías para Virus Epstein Barr, Citomegalovirus, y Bartonella henselae negativas. Orina normal, urocultivo sin desarrollo. Persiste con fiebre, agrega exantema macropapular evanescente en tronco, sin otros síntomas. Al 7° día de internación nuevo hemocultivo: Salmonella Typhi sensible a ampicilina que recibe por 14 días. Buena evolución. Discusión: La fiebre tifoidea es una enfermedad infectocontagiosa, aguda, potencialmente mortal. Las condiciones socioeconómicas son determinantes en su transmisión. La sensibilidad del hemocultivo es mayor durante la primera semana de enfermedad, por lo que en ocasiones es necesario reiterarlo. Sus manifestaciones clínicas inespecíficas y la baja incidencia hacen que esta etiología no sea habitualmente sospechada en nuestro medio. Por tanto, es importante aumentar el índice de sospecha y considerar entre los diagnósticos diferenciales de SFP esta etiología.
Introduction: Infections are the most frequent etiology of prolonged febrile illness (PFI). Although enteric fevers are a possible cause, their prevalence has significantly diminished in Uruguay, due to improved socio-sanitary conditions. Objective: To communicate the case of an adolescent with a currently exceptional etiology of PFI. Clinical case: 14 years old, healthy, suburban area. Two days prior to admission the patient has pain in upper hemi abdomen. Adds mild holocranial headache and occasional vomiting. 5 days prior to admission axilary temperature of 40°C, one daily peak, without other symptoms. Normal lower digestive and urinary transit. Physical examination: lucid, good general aspect, pain at deep palpation in epigastrium. No peritoneal irritation. Rest is normal. Laboratory: leukocytes 5200 mm3, C-reactive protein 71.4mg/dL, blood culture shows no growth. Abdominal sonogram, thoracic X-ray and echocardiogram are normal. Negative serology for Epstein Barr Virus, Cytomegalovirus and Bartonella henselae. Normal urine, urine culture with no growth. Fever persists, adds evanescent macropapular exanthema in on the trunk, without other symptoms. On the 7th day in hospital a new blood culture shows Salmonella Typhi sensitive to ampicillin, which he receives for 14 days. Good evolution. Discussion: Typhoid fever is an acute, life-threatening, infectious disease. Socioeconomic conditions are determinant in its transmission. Blood culture sensitivity is greater during the first week of the disease, that is why it must occasionally be repeated. Its unspecific clinical manifestations and low incidence make this etiology not be usually suspected in our surroundings. It is therefore important to increase our suspicion and to consider it amongst differential diagnosis in PFI.

As sorologias para vírus Epstein Barr, Citomegalovírus e Bartonella henselae foram negativas. Urina normal, urocultura sem desenvolvimento. Persiste com febre, acrescenta erupção macropapular evanescente no tronco, sem outros sintomas. No 7º dia de internação, nova hemocultura: Salmonella Typhi sensível à ampicilina, que recebeu por 14 dias. Boa evolução. Discussão: A febre tifóide é uma doença infecciosa aguda, potencialmente fatal. As condições socioeconômicas são decisivas na sua transmissão. A sensibilidade da hemocultura é maior durante a primeira semana da doença, por isso às vezes é necessário repeti-la. Suas manifestações clínicas inespecíficas e baixa incidência fazem com que essa etiologia não seja usualmente suspeitada em nosso meio. Portanto, é importante aumentar o índice de suspeição e considerar essa etiologia entre os diagnósticos diferenciais da SFP.

BACKGROUND: The over prescription of antibiotics for acute respiratory infections is a major public health problem worldwide. Aim: To evaluate the frequency of prescription of antibiotics for non-pneumonia acute respiratory infections in private outpatient clinics in individuals without chronic diseases or immunosuppression. MATERIAL AND METHODS: All medical records of adult consultants in a national network of private ambulatory medical centers during May 2018 whose primary diagnosis corresponded to acute respiratory infections not pneumonia (ICD10) were identified and retrospectively analyzed, excluding those with chronic respiratory conditions or states of immunosuppression. RESULTS: Of the 38,072 consultants (aged 36 years, 63% women) who met this criterion, 54% (n = 20,499) received a prescription for at least one antibiotic. The diagnoses that most frequently received this prescription were acute bronchitis (28.7%), acute sinusitis (16.5%) and acute tonsillitis (16.2%). The most frequently prescribed antibiotic globally was azithromycin (37.4%), followed by amoxicillin (20.1%) and amoxicillin plus clavulanic acid (17.7%). Levofloxacin prescription reached 12.5% of total prescriptions. CONCLUSIONS: An antibiotic was prescribed in more than half of the non-pneumonia outpatient acute respiratory infections. Azithromycin was the most prescribed antibiotic, while levofloxacin exceeded 10% of prescriptions. These results reinforce the need to implement an antibiotic prescription surveillance system at the outpatient level.

Absence of adequate treatment for Helicobacter pylori (H. pylori) infection leads to prolonged life time colonization which is responsible for complications. Antibiotics resistance is the main cause of eradication failure in H. pylori infection, thus our study aimed to evaluate the efficiency and tolerability of standard triple therapy vs. quadruple regimen therapy in H. pylori eradication in Egypt.

Antecedentes: Las recomendaciones de esquemas para erradicar Helicobacter pylori se encuentran ampliamente dis- ponibles. Este es un patógeno de alta prioridad para búsqueda y desarrollo de nuevos y efectivos tratamientos. Objetivo: Descri- bir la respuesta terapéutica con terapia de rescate para infección por H. pylori, Hospital Escuela, Tegucigalpa, diciembre 2016-abril 2017. Métodos: Estudio descriptivo longitudinal retrospectivo en pacientes consecutivos con sintomatología gastrointestinal e in- fección conirmada por H. pylori. Mediante el registro del Servi- cio de Gastroenterología, Departamento de Medicina Interna, se identiicaron pacientes positivos por H. pylori. Se registraron datos sociodemográicos, clínicos y diagnósticos. El tratamiento de res- cate brindado fue, vía oral por 10 días: levoloxacina 500 mg/día, esomeprazol 40 mg dos veces/día, amoxicilina 1 gr dos veces/ día. La conirmación de la erradicación fue realizada 4-8 semanas postratamiento. Se registró información sobre la adherencia al tra- tamiento y los efectos secundarios. Resultados: Se analizaron 30 casos; 56.7% (17) pacientes nuevos y 43.3% (13) pacientes con al menos un fracaso. En el 16.0% (5) no hubo conirmación de erra- dicación; se obtuvo una tasa de erradicación del 72.0% (18/25), IC95% 50.6-87.9; siendo 78.5% (11/14) en pacientes nuevos ver- sus 63.6% (7/11) en fracasos previos, IC95% -9.6-54.0, p=0.318. Discusión: La tasa de erradicación en este grupo de pacientes no fue satisfactoria. Actualmente el tratamiento con levoloxacina es recomendado como terapia de segunda línea o de rescate en regiones con baja o alta resistencia a la claritromicina, aunque la resistencia a quinolonas ha aumentado en los últimos años en va- rios países...(AU)

Abstract Some evidence in vitro suggested that amoxicillin and fluoride could disturb the enamel mineralization. Objective: To assess the effect of amoxicillin and of the combination of amoxicillin and fluoride on enamel mineralization in rats. Methodology: In total, 40 rats were randomly assigned to four groups: control group (CG); amoxicillin group (AG - amoxicillin (500 mg/kg/day), fluoride group (FG - fluoridated water (100 ppm -221 mg F/L), and amoxicillin + fluoride group (AFG). After 60 days, the samples were collected from plasma and tibiae and analyzed for fluoride (F) concentration. The incisors were also collected to determine the severity of fluorosis using the Dental Fluorosis by Image Analysis (DFIA) software, concentration of F, measurements of enamel thickness, and hardness. The data were analyzed by ANOVA, Tukey's post-hoc test, or Games-Howell post-hoc test (α=0.05). Results: Enamel thickness of the incisors did not differ statistically among the groups (p=0.228). Groups exposed to fluoride (AFG and FG) have higher F concentrations in plasma, bone and teeth than those not exposed to fluoride (CG and AG). The groups showed a similar behavior in the DFIA and hardness test, with the FG and AFG groups showing more severe fluorosis defects and significant lower hardness when compared with the AG and CG groups, with no difference from each other. Conclusion: The rats exposed to fluoride or fluoride + amoxicillin developed dental fluorosis, while exposure to amoxicillin alone did not lead to enamel defects.

La otitis media aguda (OMA) es una patología muy común en pediatría y constituye la indicación más frecuente de prescripción de antibióticos en la infancia. Para el diagnóstico se tienen en cuenta hallazgos en la otoscopia, diversos signos clínicos y el tiempo de evolución de los síntomas principales. La decisión de iniciar antibioticoterapia debe determinarse según cada paciente. La espera vigilante como alternativa a la antibioticoterapia inmediata en casos seleccionados reduce el uso de antibióticos sin aumentar el riesgo de daño al paciente y ha demostrado ser una medida costo-efectiva. El fármaco de elección para el tratamiento empírico de la OMA es la amoxicilina, aunque según nuestros resultados es la amoxicilina-IBL la utilizada como primera línea en ambos servicios.
Acute otitis media (AOM) is a pathology commonly found in pediatrics, and the most frequent cause of antibiotics prescription in infants. For its diagnostics, several criteria are taken in consideration, such as otoscopy observations, diverse clinical signs, and the time of evolution of the main symptoms. The decision to initiate antibiotic therapy must be determined particularly for each patient. As an alternative to immediate antibiotic therapy, watchful waiting is preferred in certain cases to reduce the antibiotic use without elevating the patients' risk and has been proven to be a cost-effective approach. The preferred drug for empiric antibiotic therapy in AOM is amoxicillin, although we have observed that the first choice in both our services, pediatrics and otorhinolaryngology, is amoxicillin-IBL.

A proteinose alveolar pulmonar (PAP) é rara e caracterizada por preenchimento alveolar com material lipoproteináceo. A proteinose alveolar é caracterizada por um alvéolo com material eosinofílico, acelular, finamente granular, com fendas de colesterol. Este relato de caso descreve um paciente do sexo masculino, 2 anos, portador de hipogamaglobulinemia. O paciente foi internado com quadro compatível com Stevens- Johnson após uso de amoxicilina e clavulanato para quadro de otite média aguda. Posteriormente, foi encaminhado à unidade de terapia intensiva devido à piora respiratória clínica e radiológica. Biópsia pulmonar: proteinose alveolar com alvéolos distendidos por material proteináceo, eosinofílico e grumoso com infiltrado linfo- histiocitário local. A proteinose alveolar pulmonar é rara e o diagnóstico correto deve ser realizado para que seja realizado tratamento adequado e acompanhamento da evolução. Deve-se atentar para complicações, especialmente infecções oportunistas.
Pulmonary alveolar proteinosis (PAP) is rare and it is characterized by alveolar filling with lipoproteinaceous material. Alveolar proteinosis is characterized by an alveolus with eosinophilic, acellular, finely granular material, with cholesterol cracks. This case report describes a 2-yearold male patient with hypogammaglobulinemia. The patient was hospitalized with Stevens-Johnson-compatible condition after use of amoxicillin and clavulanate for acute otitis media. Subsequently, he was referred to the intensive care unit due to worsening clinical and radiological breathing. Lung biopsy: alveolar proteinosis with alveoli distended by proteinaceous, eosinophilic and lumpy material with local lymphohistiocytic infiltrate. Pulmonary alveolar proteinosis is rare and the correct diagnosis must be made in order to carry out an appropriate treatment and follow-up of the evolution. Attention should be paid to complications, especially opportunistic infections.

Resumen Helicobacter pylori (H. pylori) es un bacilo gramnegativo microaerófilo, capaz de colonizar la mucosa gástrica. Este microorganismo infecta a más de la mitad de la población mundial, por lo que se ha convertido en la infección bacteriana más común. La prevalencia de la infección y de las enfermedades asociadas a ella es alta, sobre todo en países en vías de desarrollo. El tratamiento recomendado para la erradicación es la triple terapia; sin embargo, su eficacia ha disminuido por el desconocimiento del patrón de susceptibilidad bacteriano por parte del personal médico y dada la aparición de cepas resistentes. La resistencia en H. pylori se asocia con la capacidad de adaptación de la bacteria a ambientes hostiles y al uso de los antibióticos. En Colombia, existen reportes acerca de que H. pylori presenta resistencia a amoxicilina, metronidazol, claritromicina, furazolidona, levofloxacina y tetraciclina. Los estudios del patrón de susceptibilidad determinaron que la frecuencia de resistencia de H. pylori es variable y demuestran la falta de datos en la mayoría del territorio del país. Sobre la base de lo anterior, el objetivo de esta revisión es describir los porcentajes de resistencia de H. pylori a los antibióticos amoxicilina, metronidazol, claritromicina, furazolidona, levofloxacina y tetraciclina, usados en el tratamiento de la infección en los estudios realizados en Colombia.
Abstract Helicobacter pylori (H. pylori) is a microaerophilic gram-negative bacillus that colonizes the gastric mucosa. It infects more than half the world's population, making it the most common bacterial infection. The prevalence of infection and associated diseases is high in developing countries. The recommended treatment for its eradication is triple therapy; however, its efficacy has decreased due to the lack of knowledge of the bacterial susceptibility pattern among the medical staff and the emergence of resistant strains. H. pylori susceptibility is associated with the bacteria's ability to adapt to hostile environments and the use of antibiotics. In Colombia, it has been reported that H. pylori is resistant to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin, and tetracycline. Studies on the susceptibility pattern have determined that the frequency of H. pylori susceptibility is variable and demonstrate the lack of data in most of the Colombian territory. With this in mind, the objective of this review is to describe the percentage of resistance to amoxicillin, metronidazole, clarithromycin, furazolidone, levofloxacin and tetracycline, which are used for the treatment of H. pylori infection, according to studies conducted in Colombia.
