Clinical characteristics of deep neck abscess in children; 15 year experience in a university hospital / 소아과

PURPOSE: The objective of this study was to clarify the presentation, associated preceding illness, pathologic organisms, treatment and outcome of deep neck abscess in children according to age and location. METHODS: We retrospectively reviewed the in-patient charts of children treated at our hospital for deep neck abscess. Thirty-five such patients were identified as having been treated from March 1990 to December 2005. RESULTS: A total of 35 were enrolled in our study: 25 boys and 10 girls. Their ages ranged from 11 months to 15 years. Presenting symptoms included mass, fever, irritability, trismus and dysphagia. The most commonly known associated preceding illness was viral upper respiratory infection (53%). The most common site of infection was the submandibular space (37%). Bacteria was identified in 16 patients. The most common pathogen was Staphylococcus aureus. Thirteen (37%) children recovered from the infection with conservative treatment and twenty-four (68%) children received surgical drainage. The duration of hospitalization was longer in the group who underwent surgery than in the group who were managed with conservative treatment. No complication occurred. CONCLUSION: Unexplained torticollis, trismus or irritability in children were suggestive of deep neck abscess. Our results demonstrate that deep neck abscesses in children is respond well to conservative treatment if diagnosed early.

Clinical Study of Acute Pyogenic Osteomyelitis in Children / 소아과

PURPOSE: Acute pyogenic osteomyelitis is uncommon in children. Delayed diagnosis and inappropriate treatment are leading to growth failure and deformation. We review the clinical manifestations and treatment of acute osteomyelitis in children according to age. METHODS: A retrospective analysis was made of 32 patients who underwent antibiotic management or operation between Aug 1989 and Dec 2003 for acute pyogenic osteomyelitis in age from 0 to 15 years old. RESULTS: The study group was composed of 21 boys and 11 girls. The subjects were divided into four groups according to age: 0-1 yr (n=6), 1-5 yr (n=11), 6-10 yr (n=8), and 11-15 yr (n=7). Nineteen cases were diagnosed in Winter. Femur was the most common infected site (37.5%). There were no predisposing factor in 17 patients, and 7 of 15 patients had trauma history. Sepsis was important predisposing factor in neonates. The chief complaints were pain, swelling and fever. S. aureus (61%) is the most common organism. Twenty-nine patients were treated with operation and concomitant antibiotics. Two cases had sequelae in follow-up period: One is avascular necrosis of femur and the other is discrepancy of leg length. CONCLUSION: In our review, because of poor prognosis in septic neonates, we recommend to treat actively neonatal sepsis and prevent or detect osteomyelitis early. Because most of patients were diagnosed and treated in orthopedic surgery, the rate of operation was too high. So, protocol for further evaluation and management of acute osteomyelitis in pediatric patients were needed.

A Case of Actinomycotic Thyroiditis in a Child with Fourth Branchial Cleft Fistula / 소아과

Fistulas of the fourth branchial pouch have an external opening in the neck and the inner opening at the apex of the pyriform fossa. The tract passes from the left lobe of the thyroid, resulting in acute suppurative thyroiditis in most cases. Actinomycosis is an indolent, slowly progressive infection caused by anaerobic or microaerophilic gram-positive bacteria, primarily of the genus Actinomyces. These bacteria are filamentous with branching and may colonize in the oral cavity. Actinomycosis is a chronic disease characterized by abscess formation, tissue fibrosis, and draining sinuses. We experienced a case of 6-year-old boy who had presented with a left neck mass. Neck sono showed an approximately 3 cm-sized low echoic mass in the left thyroid gland. Thyroid scan was compatible with thyroid hypofunction. Gomori-methenamine silver stain after fine needle aspiration showed colonies of bacteria, are composed of long, thin, filamentous bacteria. Barium esophagogram showed a linear barium-filled track at the left pyriform sinus. Neck excisional biopsy was consistent with the remnant of a fourth branchial cleft fistula. We report a case of actinomycotic thyroiditis in a child with fourth branchial cleft fistula, with a brief review of related literature.
