OBJECTIVE: To study the etiology, clinical features and treatment outcomes of pediatric Pott's puffy tumor (PPT). METHODS: This retrospective study was carried by reviewing medical case record of pediatrics PPT cases admitted to our hospital from January 2010 to august 2011. Data regarding the patient's demographic details, presenting symptoms and signs, etiology, laboratory findings, imaging findings, management, complications and outcomes of treatment were collected and analyzed...

Invasive aspergillosis is a life-threatening condition in patients with chronic granulomatous disease (CGD). Skin invasion by Aspergillus occurs most commonly by contiguity to a neighboring cavity. We describe an unusual case of invasive cutaneous aspergillosis presented as a large burgeoning tumor in a 4-year-old girl with CGD who underwent surgical treatment for bifocal osteomyelitis of the left leg. The skin invasion occurred 4 months after a "successful" treatment of invasive pulmonary aspergillosis. Atypical presentation and diagnostic difficulties are discussed...

This review presents techniques to optimize bone scintigraphy for evaluation of the spectrum of abnormalities associated with pediatric osteomyelitis, with an emphasis on the approaches to patient preparation and positioning and to interpretation. The diagnosis of pediatric osteomyelitis can be challenging for several different reasons. Bone scintigraphy is especially useful when the site of osteomyelitis is unclear. Other imaging modalities, including radiography, ultrasonography, and magnetic resonance imaging, all have advantages and may have a role in evaluating the condition of the child with osteomyelitis...

A girl, 7 years of age, was reported who had been suffered from migratory arthralgia, bone pain and erythematous rash. She had increased inflammatory markers such as C-reactive protein, erythrocyte sedimentation rate, and mild anemia for more than 6 months. In the beginning, she was suspected of having either juvenile idiopathic arthritis or chronic recurrent multifocal osteomyelitis. However, after about 6 months, there were abrupt increases of LDH in serum titers and blast cells were also revealed by bone marrow examination...

Streptococcus pneumoniae is an uncommon cause of osteoarticular infections (OAI) in children. The objective of this study was to investigate the clinical and laboratory characteristics of pneumococcal OAI before and after the introduction of the heptavalent pneumococcal conjugate vaccine (PCV7). Data were retrospectively collected from children aged <16 years who were hospitalized for pneumococcal OAI between 1997 and 2007 in four Parisian teaching hospitals. Forty-three children were included (32 with arthritis and 11 with osteomyelitis) and the median age of these children was 12...

OBJECTIVES: To describe Staphylococcus aureus infections in children with diabetes mellitus (DM). METHODS: Children with DM (cases) and S. aureus infections (2/02-6/10) were identified from a surveillance database. Patient charts were reviewed, and S. aureus isolates were characterized by molecular methods. Cases were compared to age-matched controls without DM but with CA-S. aureus skin and soft tissue infections (SSTI) using conditional logistic regression. RESULTS: Forty-seven cases were identified; 41 were matched with 123 controls...

Pediatric stress injuries result from a mismatch between (a) the burden of activity on growing bone and cartilage and (b) their intrinsic biomechanical properties. Although the presentation of stress injuries varies with the specific physical activity and the site of injury, in children it varies primarily with the degree of skeletal maturation. During the past several years, there has been a substantial increase in the incidence of pediatric stress injuries. The differential diagnosis of a stress injury in a child or adolescent can be challenging because the injury sometimes can appear aggressive at imaging assessment...

BACKGROUND: There is limited information on osteoarticular infections in human immunodeficiency virus (HIV)-infected children. The purpose of this study was to determine the effect of HIV on the epidemiology of osteoarticular infections in a setting with a high prevalence of pediatric HIV infection. METHODS: A retrospective evaluation of children presenting with acute septic arthritis or osteomyelitis from June 2005 to July 2009 was undertaken. Standard departmental protocols for the management of osteoarticular infections, including testing for HIV, were practised...

OBJECTIVE: Chronic granulomatous disease (CGD) is an inherited disorder of the Nicotinamide adenine dinucleotide phosphate reduced oxidase complex characterized by recurrent bacterial and fungal infections. Disseminated infection by combination of opportunistic agents is being increasingly reported in CGD patients. We presented in the retrospective review of medical records, the etiology, presentation, clinical characteristics the infections detected, predisposing condition and outcome of nocardiosis and actinomycosis involved in a group of pediatric patients diagnosed with CGD...

BACKGROUND: Osteomyelitis is a common pediatric musculoskeletal infection. This infection can weaken the normal bone structure, resulting in the risk of a pathologic fracture. The purpose of this study was to evaluate the risk factors for pathologic fracture in children with Staphylococcus aureus osteomyelitis. METHODS: Seventeen children who were treated for a pathologic long-bone fracture secondary to Staphylococcus aureus osteomyelitis between January 2001 and January 2009 at a tertiary-care pediatric hospital were identified...

OBJECTIVE: Previous studies have reported that contrast-enhanced sequences do not increase the sensitivity of MRI for the diagnosis of pediatric osteomyelitis and are not needed in the absence of edema on unenhanced MRI sequences. Invasive skeletal infections due to community-acquired Staphylococcus aureus are increasingly encountered in infants and young children and have a proclivity for involvement of both the unossified growth cartilage and the metadiaphyseal bone marrow of the extremities...

Pyomyositis is a pyogenic muscular tissue infection mainly occurring in immunocompromised patients. Chronic myeloid leukemia (CML) accounts for only 2-3% of cases of childhood leukemia. Herein, we report on a 17-year-old male with bilateral hip pain caused by adductor pyomyositis before beginning the treatment course of CML. CML was diagnosed by bone marrow chromosome study and was treated initially with imatinib but switched to hydroxyurea 5 days later because of poor cytoreduction response. Subsequently, white blood cell counts decreased gradually; however, the hyperleukocytosis condition resolved very slowly again until we switched back to imatinib use on the 40(th) day of hospitalization...

Osteomyelitis in adolescents is a serious disease with the potential for lifelong disability. The key to successful management is early diagnosis, including bone sampling for microbiological and pathological examination to allow targeted and long-lasting antibiotic therapy. Staphylococcus aureus is the most frequently isolated microorganism in these patients. Methicillin-resistant S. aureus (MRSA) is usually considered a nosocomial pathogen, but increasingly it is acquired in the community. We present a case of acute osteomyelitis caused by community-associated MRSA (CA-MRSA) who had never been hospitalized and had no other known risk factors for MRSA...

BACKGROUND AND OBJECTIVE: Published data from Saudi Arabia regarding autoinflammatory diseases are scarce. In this study, we describe the clinical and laboratory features of autoinflammatory diseases in Saudi children. DESIGN AND SETTING: Restrospective, hospital-based study conducted from January 2010 until June 2010. PATIENTS AND METHODS: Patients with autoinflammatory disease treated at the Pediatric Rheumatology Clinic at King Faisal Specialist Hospital and Research Center, Riyadh, over the past 10 years were included...

Brodie's abscess of the tarsal cuboid is a rare presentation of a common disease. In the present report, we describe the case of Brodie's abscess of the tarsal cuboid after a thorn prick in the foot of a 10-year-old boy. The patient was asymptomatic in the acute phase of the injury, and on presentation, no evidence was found of an open cutaneous wound. The foot radiographs showed a cavitary osteolytic lesion in the cuboid bone. Magnetic resonance imaging revealed a classic penumbra sign and an abscess in the plantar intrinsic musculature...

We report a case of Lemierre syndrome secondary to Streptococcus pyogenes in a 22-month-old girl. This case report and literature review took place at a pediatric intensive care unit at a freestanding tertiary children's hospital. Diagnosis occurred after the discovery of left internal jugular thrombus and multiple metastatic infection sites including the right knee, kidneys, lungs, and brain. Lemierre syndrome can occur in young children secondary to S. pyogenes, and a classic presentation may not occur. A high index of suspicion is crucial to the diagnosis...

OBJECTIVE: To evaluate the clinical features, causative pathogens and outcomes-related to acute hematogenous osteomyelitis and septic arthritis in pediatric patients. MATERIAL AND METHOD: The authors conducted a retrospective cohort study of patients under 15 years of age with diagnosis of acute hematogenous osteomyelitis (AHO) and/or septic arthritis (SA), treated at Queen Sirikit National Institute of Child Health from 1996 to 2006. Demographic data, clinical characteristics, bacterial spectrum, and outcomes were collected...

OBJECTIVES: Intraosseous line (IO) use has been described in prehospital settings, with some studies in the emergency department (ED). However, population-based studies describing IO line use across diverse ED and hospital settings are sparse, and the true incidence of complications remains unknown. METHODS: This was a retrospective cohort study using administrative data from 450 California hospitals and EDs. We included all children aged 0 to 18 years with ED or inpatient visits from 2005 through 2007...

BACKGROUND: The emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) has complicated the conventional management of osteomyelitis. While oral clindamycin is commonly used to treat acute CA-MRSA osteomyelitis, the emergence of inducible clindamycin resistance among CA-MRSA isolates has made alternative therapy necessary. The excellent oral bioavailability, susceptibility profile, favorable palatability, and low cost of trimethoprim-sulfamethoxazole (TMP-SMX) make this drug an attractive option for treating osteomyelitis, yet its clinical efficacy for osteomyelitis has not been established...
