Pyriform sinus fistula (PSF) is a persistent embryologic third or fourth pharyngeal pouch, which typically presents as a congenital sinus tract that originates from the pyriform sinus. PSF is among the most uncommon congenital malformation of the neck. The usual clinical manifestations are either acute thyroiditis or abscess, usually on the left side of the neck. We report a case of PSF in a 9-year old female with a left cervical abscess who had been diagnosed by barium esophagogram and treated endoscopically by injection of histoacryl.

BACKGROUND: Vibrio parahaemolyticus belonged to the new 03:K6 serotype was demonstrated an unusual potential to spread and an enhanced propensity to cause infection in the worldwide. Recently, increased numbers of V. parahaemolyticus 03:K6 had been isolated in Korea, and we analyzed the prevalence and molecular genetic characteristics of V. parahaemolyticus 03:K6 isolates. METHODS: V. parahaemolyticus were isolated from clinical specimens of patients with diarrhea in Hanyang University Hospital, Seoul, Korea, from 1998 to 2005. The serovars of isolates were determined by slide agglutination test with specific antisera. All isolates were examined for the presence of tdh/trh genes. AGS-PCR method detecting the new 03:K6 clone was used in this study. We analyzed clonality of these isolates by infrequent restriction site-polymerase chain reaction (IRS-PCR). RESULTS: Thirty-six strains were isolated from 1998 to 2005. The main serotype of isolates were 03:K6 (24/36: 67%), All of them have tdh gene but not trh gene and an unique toxRS gene of the new 03:K6. The morphotypes of 03:K6 isolates show a same pattern of IRS-PCR, but can easily be differentiated from non-03:K6 and 04:K68 isolates. CONCLUSION: The 03:K6 was a main serotype of V. parahaemolyticus isolated from 1998 to 2005 and they show same molecular characteristics.

We reviewed 43 feet in 23 patients who had myelodysplasia and underwent surgical treatment for foot deformities at the Seoul National University Children's Hospital from 1986 to 1991. There were 12 boys, and 11 girls. Eleven patients had myelomeningocele, whereas 11 patients had lipomyelomeningocele and 1 patient had occult spinal dysraphism. The mean age at operation was 7 years 1 month(range, 2 month-14 years). The affected neurological levels were below L1 or L2-2 patients, below L3 in 2 patients, below L4 in 12 patients, below L5 in 5 patients, and sacral in 2 patients. The average length of follow-up was 3 years(range, lyear-7years and 1 month). There was significant correlation between the types of foot deformity and the neurosegmental level as follows : 4(100%) feet of varus deformity in below L3, 13(61%) feet of varus deformity in below L4, 4(40%) feet of cavus deformity and 5(50%) feet of calcaneal deformity in below L5, and 4(100%) feet of cavus deformity in below sacral level. Equinovaurs, however, was observed irrespective of the neurosegmental level. Various kind of bony surgery (41 feet), soft tissue release(40 feet), and tendon transfer(36 feet) were performed to obtain the plantigrade foot. Satisfactory results were obtained in 30 of 43(70%) feet. Unsatisfactory results were due to recurrence(8 feet), overcorrection(3 feet), and incomplete correction(2 feet) of the foot deformity. Lipomeningocele, preoperative ankle valgus deformity and retethering of the nerve roots were high risk factors which were closely related to the recurrence of the foot deformity. To reduce the recurrence of foot deformity, we suggest that complete correction of the deformity, the maintenance of correction, and early detection of neurologic change due to retethering are mandatory.
