Polyarthritis, hyperuricemia and right shoulder pain: a report of one case with literature review / 中华风湿病学杂志

Objective:To improve the clinical differential diagnosis ability of rheumatoid arthritis (RA) complicated with gout and septic arthritis (SA).Methods:The clinical characteristics, diagnosis, and treatment of one RA patient with hyperuricemia and recurrent swelling and pain in right shoulder were reported and discussed.Results:A patient, with a history of RA for 10 years, hyperuricemia for 8 years, recurrent swelling and pain in right shoulder for 1 year. RA, gout, and SA were diagnosed before, and the response was poor after symptomatic treatment. In recent 1 month, the symptom was aggravated with the formation of fistula on the right shoulder. The laboratory tests for tuberculosis T cell interferon release test (IGRA) and tuberculin (PPD) test were negative, and the CD4 + cell count decreased. The comprehensive analysis of the imaging with right shoulder showed MSU deposition on right shoulder, with bone erosion, bone destruction, bone marrow edema, joint effusion, and multiple sites of connective tissue involvement (synovial bursa, tendon sheath, tendon, and muscle) GeneXpert MTB/RIF (GeneXpert), metagenomic next-generation sequencing (mNGS) of puncture fluid and joint fluid culture prompted Mycobacterium tuberculosis complex group. He was finally diagnosed with RA, gout, and osteoarticular tuberculosis (OAT). Symptoms were relieved after symptomatic treatment. Conclusion:RA patients with hyperuricemia have recurrent single arthritis. In addition to considering for gout, the presence of OAT should also be considered. The immune functional status of the patient and drug used may interfere with the interpretation of immune function tests. It is necessary to integrate the clinical characteristics of patients, a variety of imaging examinations, and etiological detection to confirm the diagnosis and avoid misdiagnosis.

Vasculite por tuberculose ocular associada a eritema nodoso e à doença de Poncet / Ocular tuberculosis vasculitis associated with erythema nodosum and Poncet's disease

RESUMO A tuberculose intraocular deve ser sempre aventada como diagnóstico diferencial devido à sua alta significância nos agravos, além da alta morbidade da infecção sistêmica. Essa condição pode se apresentar associada a manifestações extraoculares pouco prevalentes da tuberculose. O autor relatou um caso de vasculite por tuberculose ocular, associada a eritema nodoso e à doença de Poncet, com resolução dos achados e sintomas após esquema padrão para tuberculose.

ABSTRACT Intraocular tuberculosis should always be deemed as a differential diagnosis due to its high importance, in addition to the high morbidity of systemic infection. This condition may be associated with extraocular manifestations that are not prevalent in tuberculosis. The author reported a case of ocular tuberculosis vasculitis associated with erythema nodosum and Poncet's disease, with resolution of the medical findings and symptoms after the standard treatment for tuberculosis.

A case report of osteoarticular mucormycosis in post-COVID-19 patient

Mucormycosis is a rare invasive fungal disease often seen in immunocompromised individuals. The mucormycosis cases increased in COVID-19 patients from March to June 2021. Here, we report the case of a 61-year-old male hypertensive patient with COVID-19 who was treated with antibiotics and steroids for recovery. After treatment, he developed a secondary infection of osteoarticular mucormycosis which is uncommon and rare. We report this case here in detail.

Espondilodiscite em idade pediátrica ­ uma doença rara, um diagnóstico difícil / Spondylodiscitis in pediatric age ­ a rare disease, a difficult diagnosis

Introdução e objetivo: a espondilodiscite é a infeção que atinge o disco intervertebral e as vértebras contíguas e representa dois a quatro % do total das infeções osteoarticulares em idade pediátrica. O agente patogénico é identificado em cerca de metade dos casos, sendo o Staphylococcus aureus o mais frequentemente isolado. Estudos recentes demonstram que entre os seis meses e os quatro anos a Kingella kingae tem um papel etiológico importante. O objetivo da exposição deste caso clínico foi chamar atenção para esta patologia rara cujo diagnóstico é difícil e exige um elevado nível de suspeição. Descrição do caso: criança de 16 meses, sexo masculino, com antecedentes de obstipação, é trazida múltiplas vezes à Urgência Pediátrica por quadro com mais de um mês de evolução de irritabilidade persistente, dor abdominal e recusa da marcha de agravamento progressivo. Na segunda vinda à Urgência Pediátrica apresentava dorsolombalgia à palpação da coluna dorsolombar e diminuição da lordose lombar, o que motivou a realização de avaliação analítica, sumária de urina, ecografia renal e vesical e radiografia dorsolombar sem alterações. Na terceira vinda à Urgência Pediátrica foi decidido internamento e solicitada ressonância magnética nuclear dorsolombar e cintigrafia óssea que revelaram espondilodiscite em D7-D8. Parâmetros analíticos sem alterações valorizáveis, exceto discreta elevação da velocidade de sedimentação. Hemoculturas e restante estudo etiológico negativo. Iniciou terapêutica endovenosa com cefu-roxime e flucloxacilina, com melhoria progressiva das queixas álgicas. Aquando da alta, assintomático, mantendo flucloxacilina oral até completar seis semanas de tratamento. Reavaliado posteriormente, encontrando-se assintomático, com um exame físico, reavaliação analítica e radiografia dorsolombar sem alterações. Conclusões: a espondilodiscite é uma identidade de difícil diagnóstico, especialmente na criança, devido à sua raridade, clínica inespecífica, impossibilidade de as crianças verbalizarem os seus sintomas e aos sinais radiológicos tardios, requerendo um alto índice de suspeição. O intervalo médio de tempo entre o início dos sintomas e o diagnóstico é de três semanas a três meses. A ressonância magnética é o exame de escolha. As hemoculturas são, muitas vezes, negativas. O pilar do tratamento é a antibioterapia por várias semanas, mas a sua escolha e duração são controversas. O tratamento inadequado pode originar dor crônica, sequelas ortopédicas graves e complicações neurológicas devastadoras. Quando atempada e adequadamente tratada, a maioria dos casos apresenta uma evolução clínica benigna e autolimitada.

Introduction and objective: spondylodiscitis is an infection that affects the intervertebral disc and the contiguous vertebrae. It represents two to four % of all osteoarticular infections in pediatric age. The pathogen is identified in about half of the cases, with Staphylococcus aureus being the most frequently isolated. Recent studies show that between six months and four years, Kingella kingaehas an important etiological role. The purpose of the presentation of this clinical case was to draw attention to this rare pathology whose diagnosis is difficult and requires a high level of suspicion. Clinical case description: a sixteen-month-old male, with a history of constipation, is brought multiple times to the Pediatric Emergency Department for a clinical picture with more than a month of evolution of persistent irritability, abdominal pain and refusal to walk, with progressive worsening. On the second visit to the Pediatric Emergency Department, he presented dorsolombalgia on palpation of the dorsolumbar spine and decreased lumbar lordosis, which led to the performance of analytical evaluation, urinalysis, renal and bladder ultrasound and dorsolumbar radiography, all without changes. On the third visit to the Pediatric Emergency Department, hospitalization was decided and dorsolumbar nuclear magnetic resonance and bone scintigraphy were requested, revealing spondylodiscitis in D7-D8. Analytical parameters had no changes, except for a slight increase in erythrocyte sedimentation rate. Blood cultures and remaining etiological study negatives. Intravenous therapy with cefuroxime and flucloxacillin was started with progressive improvement of pain. Upon discharge he was asymptomatic and maintained oral flucloxacillin until a total of six weeks of treatment. He was subsequently reassessed and remained asymptomatic, with a physical examination, analytical evaluation and dorsolumbar radiography without changes. Conclusions: spondylodiscitis is an identity that is difficult to diagnose, especially in children, due to its rarity, unspecific clinic, inability for children to verbalize their symptoms and late radiologic signs, requiring a high index of suspicion. The average time between the onset of symptoms and the diagnosis is three weeks to three months. Magnetic resonance imaging is the exam of choice. Blood cultures are often negative. The mainstay of treatment is antibiotic therapy for several weeks, but its choice and duration are controversial. Inappropriate treatment can lead to chronic pain, severe orthopaedic sequelae and devastating neurological complications. When timely and properly treated, most cases have a benign and self-limited clinical course.

Piomiositis, artritis séptica y osteomielitis aguda porStaphylococcus aureus meticilino resistente de la comunidad enpaciente pediátrico / Pyomyositis, septic arthritis and acute osteomyelitis due tocommunity methicillin-resistant Staphylococcus aureus in apediatric patient

Las infecciones osteoarticulares y musculoesqueléticas son patologías infecciosas relativamente infrecuentes en la infancia, afectando generalmente a varones y menores de 5 años. Países desarrollados reportan una incidencia anual de osteomielitis de 10 a 80/100.000 niños y de 4 casos/100.000 niños para artritis séptica. En países tropicales, la piomiositis tiene una incidencia de un caso por cada 2.000 habitantes. El Staphylococcus aureus es el principal agente causal. En la infancia la vía más común del legada del germen a la articulación es la hematógena. Hasta en un 30% de niños coexisten osteomielitis aguda y artritis séptica. Se presenta el caso de preescolar masculino de 3años, quien posterior a aplastamiento de miembro inferior izquierdo, presenta aumento de volumen, dolor y limitación para la marcha, asociándose 9 días después fiebre de 39.5°C,acudiendo al Hospital Universitario de Caracas. La anamnesis, evaluación clínica y estudios paraclínicos fueron sugestivos depiomiositis de muslo izquierdo, osteomielitis de fémur izquierdo y artritis séptica de rodilla izquierda. Se indica antibioticoterapiacon cobertura para Staphylococcus aureus (ciprofloxacina y clindamicina). Se realizó artrotomía evacuadora y limpieza quirúrgica de estructuras afectadas. El cultivo reportó Staphylococcus aureus sensible a ciprofloxacina, gentamicina, linezolid, rifampicina, trimetropin/sulfametoxazol; resistentea clindamicina, eritromicina, oxacilina, por lo que se omitióclindamicina y se indicó trimetropin/sulfametoxazol. Cumplió21 días de tratamiento intravenoso, observándose evolución satisfactoria por lo que se decidió egreso, dando continuidad con tratamiento vía oral por cuatro semanas y seguimiento interdisciplinario. El abordaje oportuno y adecuado de estas patologías disminuye el riesgo de desarrollar complicaciones(AU)

Osteoarticular and musculoskeletal infections are relatively rare infectious diseases in childhood, generally affecting men and children under 5 years of age. Developed countries report an annual incidence of osteomyelitis of 10 to 80 / 100,000 children and 4 cases / 100,000 children for septicarthritis. In tropical countries, pyomyositis has an incidence of one case for every 2,000 inhabitants. Staphylococcus aureusis the main causative agent. In childhood the most commonroute of arrival of the germ to the joint is hematogenous.Up to 30% of children coexist acute osteomyelitis and septic arthritis. We present the case of a 3-year-old male preschoolerwho, after crushing his left lower limb, presented an increasein volume, pain, and limited gait, and was associated witha fever of 39.5 ° C 9 days later, going to the University Hospital of Caracas. the anamnesis, clinical evaluation and paraclinical studies were suggestive of pyomyositis of the leftthigh, osteomyelitis of the left femur and septic arthritis of the left knee. Antibiotic therapy with coverage for Staphylococcus aureus (ciprofloxacin and clindamycin) is indicated. Evacuating arthrotomy and surgical cleaning of affected structures were performed. The culture reported Staphylococcus aureus sensitiveto ciprofloxacin, gentamicin, linezolid, rifampin, trimetropin /sulfamethoxazole; resistant to clindamycin, erythromycin,oxacillin, therefore clindamycin was omitted and trimetropin /sulfamethoxazole was indicated. He completed 21 days ofintravenous treatment, observing satisfactory evolution so hisdis charge was decided, continuing with oral treatment for four weeks and interdisciplinary follow-up. The timely and adequate approach to these pathologies reduces the risk of developing complications(AU)

El tratamiento antibiótico indicado fue combinado. El 94 % de los pacientes egresaron con buena evolución, no se registraron muertes. Conclusiones: Es importante sospechar tempranamente la osteomielitis, tomando conciencia de las manifestaciones clínicas, para agilizar los estudios diagnósticos que contribuyan a iniciar tratamiento precoz, y mejorar el pronóstico de los pacientes

Objective: To describe the characteristics of the pediatric hospitalized patients with diagnosis of osteomyelitis between 2013 and 2018 in the Hospital Universitario de Caracas. Methods: A transversal, retrospective, descriptive study was performed, in which every patient with diagnosis of acute and chronic osteomyelitis who met with all the inclusion criteria, were included. All data was collected in an instrument, designed for that matter, and then was analyzed with frequency, percentages, mean and standard deviation. Variables were compared in acute and chronic osteomyelitis with X2 calculation. Results: Male predominance was found, and average age between 5.7 years ± 3.5 standard deviation. Chronic osteomyelitis was the most frequent (68.5 % of all cases). The most predisposing underlying pathology was sickle cell disease. The most important risk factor was trauma. The most common clinical manifestations were fever and pain in both study groups. The most affected bones: tibia in 27.8 % and femur in 20.4 % of patients. The predominant microorganism was Staphylococcus aureus in 31.5 % of the cases, both in acute and chronic osteomyelitis, being methicillin resistant in 16.3 % of the isolates and in 23.3 % methicilline sensitive. The antibiotic treatment indicated in most cases was combined, followed by surgical treatment. 94 % of the patients were discharged with good outcome, no deaths were registered. Conclusions: The early suspicion of osteomyelitis is important, becoming aware of the clinical manifestations, so as to promptly apply the ideal diagnostic method and contribute to early treatment, in this way improve the patients' prognosis.

Hallazgos de tuberculosis extrapulmonar en imágenes de resonancia magnética en una paciente pediátrica / MRI findings on extrapulmonary tuberculosis in a pediatric patient

Resumen | La tuberculosis pulmonar es la más común en niños y su forma extrapulmonar corresponde aproximadamente a 30 a 40 % de los casos. Se presenta el caso de una niña indígena con tuberculosis diseminada: pulmonar, cerebral, medular y musculoesquelética, con importantes secuelas en el neurodesarrollo. Este caso ilustra el espectro de la tuberculosis extrapulmonar pediátrica en países endémicos en desarrollo. Además, evidencia la gravedad de las complicaciones neurológicas causantes de grave discapacidad y resalta el valor de las imágenes radiológicas para orientar la sospecha diagnóstica de compromiso extrapulmonar.

Abstract | Pulmonary tuberculosis is the most common in children and its extrapulmonary manifestations are present in 30% to 40% of cases. We present the case of an indigenous girl with disseminated tuberculosis: pulmonary, brain, medullary, and musculoskeletal with substantial neurodevelopmental sequelae. This case exemplifies the spectrum of pediatric extrapulmonary tuberculosis in endemic developing countries. Furthermore, it shows the severity of highly disabling neurological complications and stresses the importance of radiological imaging in guiding diagnostic suspicion of extrapulmonary involvement.

Tuberculosis osteoarticular en un paciente pediátrico / Osteoarticular tuberculosis in a pediatric patient

Introducción: La tuberculosis osteoarticular es una enfermedad inflamatoria crónica, muy rara con un cuadro clínico atípico y se presenta con una incidencia de 1-2 por ciento del total de los casos de tuberculosis. Objetivo: Exponer una forma de presentación poco frecuente de tuberculosis en Honduras Presentación del caso: Se trata de una niña de dos años con diagnóstico inicial de sinovitis en rodilla derecha de cinco meses de evolución y tratada con antibiótico y analgésico. Sin mejoría se presenta a emergencia con cambios inflamatorios. Se realiza rayos x de rodilla que muestran lesiones osteolíticas a nivel de rótula y cóndilo del fémur derecho. Baciloscopia de esputo y prueba de tuberculina negativas. Familiar de tercer grado positivo para tuberculosis hacía un año y medio. Por biopsia de tejido blando y óseo de rodilla derecha se establece el diagnóstico de artritis por Mycobacterium tuberculosis por estudio inmuno-histoquimico con tinción Ziehl Nielsen. Conclusiones: Es el primer informe de caso de tuberculosis osteoarticular en un paciente pediátrico descrito en Honduras. Por la larga evolución de la enfermedad, lo atípico de su clínica y su baja incidencia es difícil establecer el diagnóstico final. Fue imprescindible el estudio anatomopatológico por biopsia que permitiera esclarecer a los clínicos el diagnóstico e iniciar el tratamiento oportuno(AU)

Introduction: Osteoarticular tuberculosis is a chronic inflammatory disease, very rare, and with an atypical clinical picture and occurs with an incidence of 1-2 percent of all TB cases. Objective: Show a rare form of TB´s presentation in Honduras Case presentation: Two-year-old girl with an initial diagnosis of right knee synovitis of five months of evolution and treated with antibiotics and analgesics. Without improvement, she attends to emergencies service with inflammatory changes. Knee x-rays show osteolytic lesions at the kneecap level and the condyle of the right femur. Sputum bacilloscopy and negative tuberculin test were performed. She had a third-grade relative positive to tuberculosis a year and a half ago. A right knee soft tissue and bone biopsies confirm the diagnosis of arthritis by Mycobacterium tuberculosis by immuno-histochemical study with Ziehl Nielsen staining. Conclusions: It is the first osteoarticular TB case report in a pediatric patient described in Honduras. Because of the long evolution of the disease, the atypicalness of its clinic features and its low incidence, it is difficult to establish the final diagnosis. Anatomopathological study by biopsy was essential to clarify the diagnosis to clinicians and initiate timely treatment(AU)

ABSTRACT Objective: To analyze the occurrence of notified cases of bone tuberculosis in Brazil during the period from 2009 to 2018. Methods: Quantitative, descriptive and retrospective study. The data consisted of cases reported to the Notifiable Diseases Information System (SINAN) of DATASUS. To analyze the results, the non-parametric statistical Chi-squared and G tests, capable of expressing statistical associations, were used. Results: 6,442 cases of bone tuberculosis were reported in Brazil, with an average of 644.2 cases per year. The Southeast was responsible for 41.5% of the cases (n = 2676). The extrapulmonary form accounted for 87.9% (5661). There was a predominance in males (66.1%, n = 4258), Whites (41.6%, n = 2678) and in the above 35 years of age group (73.9%, n = 4757). In the data collected, the risk factor data was not correctly filled out, making reliable statistical associations impossible in this study, mainly between alcoholism, tobacco use, AIDS, diabetes, mental illness, illicit drug use and homelessness. Conclusion: There was greater notification of cases of bone tuberculosis in the Southeast and Northeast regions of Brazil, which predominantly affected young, economically productive men. Tuberculosis has a correlation with diabetes, HIV / AIDS, smoking and alcohol and drug use, according to the results of this study. Level of evidence II; Retrospective, analytical, quantitative and descriptive study.

Tuberculosis en húmero proximal. Un diagnóstico infrecuente en infecciones articulares / Tuberculosis in the proximal humerus. A rare diagnosis in joint infections

Resumen La incidencia de Tb osteoarticular es mucho menor que la pulmonar, representando 1-2% de los casos de Tuberculosis (Tb) y el 10% de los casos de Tb extrapulmonar, por lo que usualmente no es considerada para el diagnóstico diferencial de pacientes con enfermedad articular. Su diagnóstico es difícil y se basa en hallazgos clínicos, radiológicos, bacteriológicos e histológicos. Las lesiones extrapulmonares son paucibacilares y las muestras, en la mayoría de los casos, difíciles de obtener, por lo que el diagnóstico a menudo es simplemente presuntivo. La tuberculosis articular en etapas tempranas, presenta manifestaciones clínicas e imagenológicas inespecíficas. Esto puede facilitar la progresión de la enfermedad local, generando lesiones osteoarticulares graves y, finalmente, la destrucción articular. Se presenta el caso de una paciente de 60 años, intervenida quirúrgicamente por presentar manifestaciones clínicas e imagenológicas compatibles con una ruptura del manguito rotador, y cuya evolución tórpida posoperatoria, llevó al diagnóstico bacteriológico de tuberculosis de húmero proximal.

Abstract The incidence of osteoarticular TB is much lower than that of the lung, representing 1-2% of TB cases and 10% of extrapulmonary TB cases, so it is often not considered for the differential diagnosis of patients with joint disease. Its diagnosis is difficult and is based on clinical, radiological, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and specimens, in most cases, difficult to obtain, so the diagnosis is often simply presumptive. Joint tuberculosis in early stages presents nonspecific clinical and imaging manifestations. This can lead to the progression of the local disease, generating severe osteoarticular lesions and, finally, joint destruction. We present the case of a 60-year-old patient who underwent surgery due to clinical and imaging manifestations compatible with a rotator cuff tear, and whose torpid postoperative evolution led to the bacteriological diagnosis of proximal humerus tuberculosis.

Application value of metagenomic next generation sequencing in diagnosis of osteoarticular infections / 中华临床感染病杂志

Objective:To evaluate the application of metagenomic next-generation sequencing (mNGS) in the diagnosis of osteoarticular infection.Methods:The clinical data of 37 inpatients aged 32-90 year with osteoarticular infection admitted in the Department of Spine Surgery of Qingdao Chest Hospital from January to December 2019 were retrospectively analyzed. There were 31 cases of spine infection and 6 cases of other joint infection. The tissue samples were obtained from the infected sites through puncture or surgical approach in all patients. The tissue samples were subjected to routine culture of mycobacteria, aerobic bacteria and anaerobic bacteria, respectively. The gene amplification and mNGS were performed for detection of mycobacterium tuberculosis DNA (MTB-DNA). The chi-square test or Fisher’s exact test were used to compare the detection rates of pathogen and simple bacterial infection between mNGS and conventional culture. The conventional culture, mNGS and MTB-DNA amplification detection were performed for all samples; with clinical diagnosis as the gold standard, the diagnostic values of 3 methods were evaluated with receiver operating characteristic curve (ROC). Paired sample t test was used to compare white blood cell(WBC) count, erythrocyte sedimentation rate, C-reactive protein of patients before and after treatment. P<0.05 was considered statistically significant. Results:The pathogens were detected by mNGS for 42 times: bacteria for 39 times (92.8%), fungi for twice (4.8%) and Kirks body for once (2.4%). Among 37 patients there were 29 cases of pure bacterial infection (78.4%), 2 cases of pure fungi infection (5.4%), 1 case of pure Kirks body infection (2.7%), and 5 cases of mixed infection of two or more pathogens (13.5%). The detection rates of mNGS and conventional culture were 100.0% (37/37) and 67.6% (25/37), respectively ( χ2=13.987, P<0.05). The detection rates of mNGS and conventional culture in 29 patients with pure bacterial infection were 100.0% (29/29) and 69.0% (20/29), respectively ( χ2=16.913, P<0.05). The area under the ROC curve (AUC) of conventional culture, mNGS, and MTB-DNA in the diagnosis of osteoarticular tuberculosis infection was 0.958 (95% CI: 0.866-1.000, P<0.05), 1.000 (95% CI: 1.000-1.000, P<0.05) and 0.958 (95% CI: 0.866-1.000, P<0.05). All the 37 patients were treated with anti-infective drugs according to the results of mNGS and conventional culture. Among them, 28 patients received surgical intervention. The patients were followed up until April 30, 2020, 1 patient died. After 3 months of follow-up, the WBC count, erythrocyte sedimentation rate and C-reactive protein were (5.5±1.5)×10 9/L, (41±38)mm/h and (5.0±4.6) mg/L, respectively, which were lower than those before anti-infection treatment [(8.0±2.9)×10 9/L, (79±42)mm/h and(63±52)mg/L] ( t=6.536, 8.302 and 6.373, all P<0.05). Conclusion:The metagenomic next-generation sequencing may have important clinical value in the differential diagnosis of osteoarticular infection.

Homozygous HbS in A Malay Patient: A Rare Variant of Sickle Cell Disease in Malaysia

@#Sickle cell disease in Malay ethnicity is uncommon, with few cases been reported only in Malaysian Indians. Detecting sickle haemoglobin in patients with osteoarticular manifestation is not as simple as those with haemolysis crisis, due to its extremely low incidence in this country. We hereby report a case of a 19-year-old Malay female who presented with a long-standing history of disabling movement of both hip joints, intermittent painful swollen right elbow, and chronic back pain. Imaging investigations revealed features of chronic osteomyelitis and avascular necrosis while blood investigations demonstrated features of mild normochromic normocytic anaemia and extravascular haemolysis. Further blood smear and haemoglobin analysis eventually confirmed the presence of homozygous sickle haemoglobin manifesting as sickle cell anaemia. Our case has highlighted the importance of prompt identification and thorough evaluation of the cause of anaemia in a patient with disabling chronic osteoarticular problem.

Infecciones osteoarticulares en niños: experiencia de cinco años

Resumen Introducción: Las infecciones osteoarticulares (IOA) son consideradas una urgencia infectológica en niños. Los principales microorganismos causales son Staphylococcus aureus y Streptococcus pyogenes. Objetivo: Describir las características bio-demográficas y clínicas de pacientes de 2 meses a 15 años hospitalizados entre 2012 y 2017 con diagnóstico de IOA. Pacientes y Métodos: Estudio retrospectivo en un hospital pediátrico. Se revisaron fichas clínicas de pacientes internados con diagnóstico de IOA. Resultados: Se incluyó a 146 pacientes. Un 60,3% fueron de sexo masculino, mediana de edad 3 años 11 meses. El síntoma más frecuente al ingreso fue dolor articular (90%) y la mediana de PCR fue de 43 mg/L. Se obtuvo identificación microbiológica en 48%; de ellos, 67,8 % S. aureus (10,2% resistentes a meticilina). El 94,5% de los pacientes recibió de forma empírica β-lactámico anti-estafilocócico. Un 70,5% de los niños requirió procedimiento quirúrgico. A las 72 h se observó respuesta clínica y a los 4,7 días descenso de parámetros inflamatorios de laboratorio. El 88% de los pacientes cursó sin complicaciones. Conclusiones: Las IOA son más frecuentes en varones, el agente infeccioso más frecuentemente identificado fue S. aureus, por lo cual se sugiere inicio del esquema antimicrobiano con un β-lactámico anti-estafilocócico, ampliando cobertura en pacientes bajo 5 años de edad. A los 5 días del tratamiento antimicrobiano ya hay respuesta clínica y descenso de parámetros inflamatorios.

Abstract Background: Osteoarticular infections (IOA) are considered infectious emergencies. The main microorganisms isolated are Staphylococcus aureus and Streptococcus pyogenes. Aim: To describe demographic and clinical characteristics of patients from 2 months to 15 years old, hospitalized between the years 2012 and 2017 with IOA diagnosis. Methods: Retrospective study in a pediatric hospital. Clinical records of hospitalized patients with IOA were reviewed. Results: 146 met inclusion criteria. 60.3% of the patients were male, median age 3 years 11 months. The main symptom at admission was joint pain (90%) and the median CRP was 43 mg/L. 48% of the patients had microbiological identification; 67.8% were positive for Staphylococcus aureus (10.2% SAMR). 94.5% of the sample received empirical antistaphylococcal beta-lactam treatment and 70,5% had a surgical intervention. Clinical response was observed 72 hours of beginning of treatment, and a decreased in inflammatory laboratory markers was observed at 4.7 days. 88% of patients attended without complications. Conclusions: IOA infections are more common in boys, S. aureus is the main isolated pathogen, so we suggest to initiate the antimicrobial scheme with an antistaphylococcal beta-lactam, adding broad spectrum antimicrobial in children under 5 years. After 5 days of treatment, clinical resolution and decreased inflammatory laboratory parameters were observed.

Conclusions: In this cohort of children the incidence of K. kingae was 10.8 cases per 100 IOA. Kingella kingae represented the second documented etiology, after S. aureus. Age under 4 years, recent respiratory symptoms and normalization before the fifth day of quantitative CRP were statistically associated with IOA by K. kingae.

Lesiones osteoarticulares en cirujanos ortopédicos. ¿Cómo lo afrontamos? / Osteoarthicular injuries in orthopedic surgeons. How do we deal with it?

Resumen: Introducción: La toma de decisiones terapéuticas es un proceso complejo en la cual deben considerarse múltiples variables. Existe una tendencia cada vez mayor hacia la indicación quirúrgica, aunque no siempre la evidencia científica sea contundente. Entender cómo los cirujanos toman decisiones puede mejorar nuestra comprensión de la variabilidad de los tratamientos. Objetivos: exponer la situación demográfica de las lesiones osteoarticulares en los cirujanos ortopédicos de Uruguay y cómo afrontan su propia lesión e identificar aquellas variables que influyen en la toma de decisiones terapéuticas en el ortopedista. Material y métodos: Utilizando la base de datos de la Sociedad de Ortopedia y Traumatología del Uruguay se identificaron residentes y cirujanos que presentaron al menos una lesión osteoarticular. Se entrevistó telefónicamente a cada uno de los seleccionados, obteniendo las variables de interés. Resultados: En un total de 274 residentes y traumatólogos, incluimos 56 profesionales y 69 lesiones osteoarticulares. Destacamos la existencia de múltiples lesiones de tratamiento controvertido, según la evidencia científica actual. El cirujano no siempre indicó el mismo tratamiento a sí mismo respecto al que indicaría a un paciente con la misma lesión. Miedo a las complicaciones, rápida reintegración laboral, opinión de un colega experto, entre otras, fueron algunas de las variables halladas en la decisión terapéutica. Conclusiones: Cuando la lesión asienta en el propio cirujano, se observó un accionar distinto con respecto a un paciente con igual lesión.

Abstract: Introduction: Therapeutic decision-making is a complex process in which multiple variables must be considered. There is a growing trend towards surgical indication, although scientific evidence is not always blunt. Understanding how surgeons make decisions can improve our understanding of treatment variability; Objectives: To expose the demographic situation of osteoarticular injuries in orthopedic surgeons in Uruguay and how they deal with their own injury and identify those variables that influence therapeutic decision-making in the orthopedist. Material and methods: Using the Uruguayan Society of Orthopedics and Traumatology database, residents and surgeons who had at least one osteoarticular injury were identified. Each of the selected ones was interviewed by telephone, obtaining the variables of interest. Results: In a total of 274 residents and Orthopedic surgeons, we include 56 professionals and 69 osteoarticular injuries. We highlight the existence of multiple injuries of controversial treatment, according to current scientific evidence. The surgeon did not always indicate the same treatment to himself, in respect of the one that would indicate a patient with the same injury. Fear of complications, rapid job reimbursement, opinion of an expert colleague, among others were some of the variables found in the therapeutic decision. Conclusions: When the lesion settles on the surgeon itself, a different action was observed with respect to a patient with equal injury.

Osteoarticular infections in pediatrics / Infecções osteoarticulares em pediatria

Abstract Objective To collect the most up-to-date information regarding pediatric osteoarticular infections, including the epidemiological and microbiological profiles, diagnosis, and treatment. Source of data A non-systematic review was performed on the search engines PubMed, SciELO, LILACS, and Google Scholar, using the keywords "bone and joint infection", "children", "pediatric", "osteomyelitis", "septic arthritis" and "spondylodiscitis" over the last ten years. The most relevant articles were selected by the authors to constitute the database. Synthesis of data Osteoarticular infections are still a major cause of morbidity in pediatrics. Their main etiology is Staphylococcus aureus, but there has been an increase in the detection of Kingella kingae, especially through molecular methods. Microbiological identification allows treatment direction, while evidence of inflammatory activity assists in treatment follow-up. Imaging tests are especially useful in the initial diagnosis of infections. Empirical treatment should include coverage for the main microorganisms according to the age and clinical conditions of the patient, while considering the local resistance profile. Surgical procedures can be indicated for diagnosis, focus control, and function preservation. Acute complications include sepsis, deep venous thrombosis, and pulmonary embolism. Deaths are rare. Late complications are uncommon but may lead to deformities that compromise motor development. Conclusion A correct and early diagnosis, prompt implementation of adequate antimicrobial therapy, and focus control, when indicated, are critical to a better prognosis.

Resumo Objetivo Compilar as informações mais atuais referentes às infecções ostoarticulares em pediatria, inclusive perfil epidemiológico e microbiológico, diagnóstico e tratamento. Fonte dos dados Feita revisão não sistemática nos mecanismos de busca Pubmed, Scielo, Lilacs e Google Scholar, com as palavras-chave bone and joint infection, children, pediatric, osteomyelitis, septic arthritis e espondylodiscitis nos últimos 10 anos. Os artigos mais relevantes foram selecionados pelos autores para compor a base de dados. Síntese dos dados As infecções osteoarticulares ainda são causa importante de morbidade na pediatria. A sua principal etiologia é o Staphylococcus aureus, porém há um aumento na detecção de Kingella kingae, especialmente através de métodos moleculares. A identificação microbiológica possibilita direcionamento de tratamento, enquanto que as provas de atividade inflamatória auxiliam no acompanhamento do tratamento. Exames de imagem são especialmente úteis no diagnóstico inicial das infecções. O tratamento empírico deve incluir cobertura para os principais microrganismos, de acordo com a faixa etária e as condições clínicas do paciente, considerando o perfil de resistência local. Procedimentos cirúrgicos podem ser indicados para diagnóstico, controle do foco e preservação da função. As complicações agudas incluem sepse, trombose venosa profunda e embolia pulmonar. Óbitos são raros. As complicações tardias são incomuns, mas podem levar a deformidades que comprometem o desenvolvimento motor. Conclusão O diagnóstico correto e precoce, com pronta instituição de terapia antimicrobiana adequada e controle do foco, quando indicado, é fundamental para um melhor prognóstico.

Perthes-Like Disease Masquerading Non-Classical MPS

Abstract Mucopolysaccharidoses (MPS) are inborn errors of metabolism caused by deficient lysosomal enzymes, leading to organomegaly, hip osteonecrosis, coarse facial features, bone deformities, joint stiffness, cardiac and pulmonary symptoms (MPS VI) or hypermobility (MPS IVA). Some patients may present with non-classical forms of the disease in which osteoarticular abnormalities are the initial symptoms of non-classical forms. As orthopedists and surgeons are the specialists most frequently consulted before the diagnosis, it is critical that MPS may be considered as a differential diagnosis for patients with bone dysplasia. Experts in Latin America reviewed medical records focusing on disease onset, first symptoms and the follow-up clinical and surgical outcomes of non-classical MPS VI and IVA patients. All patients displayed orthopedic issues, which worsened over time, followed by cardiac and ophthalmological abnormalities. Our findings enlighten the necessity of including non-classical MPS as possible diagnosis for patients who report osteoarticular abnormalities in absence of inflammation.
