BACKGROUND: Peripheral blood stem cell transplantation in children has some difficulties compared with adult cases. Despite the children's total blood volume is small, they have a relatively higher volume of blood per weight than adults. Also, it is hard for the children to maintain 2 central vein during leukapheresis to shorten the time consumed. We compared the artery-harvest and central vein-harvested group for possible risk and stem cell yield in pediatric patients with malignancies. METHODS: From August, 1995 to January, 1997, 21 leukapheresis was performed by 7 patients. The patients who could have 2 central veins for leukapheresis were included in vein-harvested group and the patients who could have only 1 central vein were included in artery-harvested group. The peripheral vein was not used for leukapheresis. COBE Spectra(COBEBCT, Lakewood, CO) was used and priming was done by packed RBCs in patients weighing less than 20kg. Stem cell yield was assessed by MNC, CD34+, CFU-GM, respectively. During leukapheresis, the patients were closely monitored for change in vital sign, evidence for thrombosis, bleeding, hypocalcemia, etc. RESULTS: There was no serious complication in each group of patients. After the leukapheresis, WBC and platelet count decreased but Hb level was increased due to reinfusion of primed packed RBCs. Average flow rate was higher in vein-harvested group but there was no difference in time consumed and results in stem cell assay. CONCLUSION: Peripheral stem cell harvest in children by radial artery can be performed safely and easily without an increased risk or complication. In younger children, it is possible to achieve even more higher stem cell yield. If the patient is unable to maintain 2 central vein for leukapheresis, transient radial arterial catheterization is a safe and convenient method.

So many modalities have been suggested for the treatment of servere pain and ankylosis of the elbow with destruction of the articular surfaces. Among them, two major methods which have been widely used are resection arthroplasty and prosthetic replacement arthroplasty. However prosthetic replacement arthroplasty has some problems. Its indications are limited in the elderly inactive subjects. And there have been many kinds of complications including loosening and infection. Also, resection arthroplasty in now rarely indicated due to severe instability. From July 1980 to July 1987, we tried distraction arthroplasty in 8 cases of elbow with severe destruction of its articular surfaces, mainly in the young active persons. The average follow-up period was 45 months. The effect of distraction arthroplasty on relief of pain was not remarkable. The average increase in ROM, including that of one reankylosed elbow, was 51 ±22 degrees in flexion-extension and 48 ±23 degrees in pronstion-supinstion. No deep wound infection and instability which was main complication of resection arthroplasty were observed with our method of distraction arthroplasty. On the basis of functional results, the the results were excellent in 4, good in 1, fair in 2 and poor in 1 cases. In conclusion, distraction arthroplasty of the elbow can be one of the of effective methods reconstruction for the young active patients with the destruction of the elbow, if they are intelligent and motivated.

From March 1988 to August 1989, 51 knees with clinically suspected meniscus injuries were examined by both MRI and arthroscopy and compared their findings prospectively on the basis of arthroscopic findings to determine the accuracy of MRI in detecting meniscus injury of the knee. We used 2.0 tesla superconducting magnet imager(Spectro-20000, GoldStar, Korea) to obtain MR imaging. Our protocol for imaging was producing Tl sagittal images by spinecho technique and T2 coronal images by gradient echo technique, interleaved at 4mm continuously while the patient's knee was in 8–10 degrees of external rotation and surface coil was placed posteriorly to the knee in supine position. We grouped and correlated the findings of MRI with the arthroscopic findings. With this noninvasive MRI, we could obtain multiplanar, high quality images without compliations. Compared with the arthroscopic findings, MRI resulted in a high diagnostic accuracy of 96 and 86 percent for the medial and lateral meniscus, respectively. And it aided in optimal surgical planning for the clinically suspected meniscus injuries.

Pfeiffer syndrome, an unusual type of acrocephalosyndactyly, is a complex of associated malformations, first described by Pfeiffer in 1964. In addition to the common head and face anomalies seen in other acrocephalosyndactylies, its characteristics are broad thumbs and big toes, minimal syndactyly and normal intelligence. It is inherited in autosomal dominant pattern and shows various clinical features. The author's case was a 7-year old boy, who had been managed since birth for bilateral congenital resistant clubfeet including cast correction for six months and two operations. At present he represents not only the common features described above but also some unique features, e.g. pectus excavatum, posterior dislocation of both elbows, mild genu valgum, metatarsus adductus and complex malalignment of carpal and tarsal bones. To our knowledge, there is no report on Pfeiffer syndrome in Korea. The authors report a case of Pfeiffer syndrome with review of literatures.

Ilizarov device is a circular external skeletal fixator with crossed transfixation wires and connecting rods. Its stability depends on the tension in the wire and the spatial orientation of the fixator frame. It provides extreme versatility for correction of three dimensional complex deformities including angulation, rotation, shortening and translation. In an attempt to identify the various factors that contributed to the outcome and the complications of lengthening, we reviewed the first 19 cases of leg lengthening by the Ilizarov technique in 17 patients with leg length inequality or dwarfism. Simultaneous correction of the three dimensional deformities was also aimed at in 13 patients, and osteosynthesis of congenital pseudarthrosis of the tibia in 2 patients. Follow-up periods averaged 1.6 years, ranging from 1 year to 2.8 years. The results were summarized as follows : 1. The amount of lengthening averaged 5.2cm, ranging from 2.0cm to 9.8cm. 2. The percentage increase was 27%, ranging from 9% to 58%. 3. The average healing index (month/cm) was 1.3months/cm and it was higher in the groups that had premature consolidation, complete osteotomy, single level corticotomy and neurologic compromise as compared with the groups that had adequate corticotomy, double level corticotomy and no neurologic complication. 4. The desired lengthening was obtained in 14 cases. Simultaneous correction of the deformities and osteosynthesis for nonunion were also achieved satisfactorily during lengthening. 5. There were sixteen cases of problems (84%), which were pin tract inflammation (7 cases), Transient senrory change (3 cases), knee joint flexion contracture (2 cases), nut breakage (2 cases). There were thirteen cases of obstacles (68%), which were equinus deformity(5 cases), premature consolidation (3 cases), pathologic fracture (3 cases), and delayed consolidation (2 cases). There was only one ture complication case. In conclusion, the Ilizarov technique was very effective for leg lengthening in children, particularly when three dimensional deformities were combined with leg length shortening. But a thorough knowledge of the Ilizarov technique and meticulous care during lengthening are mandatory to prevent the pitfalls and complications.

Kimura's disease is an uncommon, chronic inflammatory disease of unknown etiology. It is an important category of reactive lymphadenopathy in the oriental population. The most common sites are the subcutis of the head and neck, and parotid gland. It's clinical course is benign nature. The treatment modalities for this disease are steroid therapy, radiation therapy and surgical excision. We experienced a case of soft tissue mass in the left arm. It was slightly tender and relatively movable. We excised the mass, which was turned out to be Kimura's disease on microscopic examination.

BACKGROUND: There are limited data regarding the antifungal susceptibility of Candida albicans causing recurrent vulvovaginal candidiasis. OBJECTIVE: The aim of the present study was to evaluate the effect of azoles susceptibilities on treatment failure and recurrence of vulvovaginal candidiasis. METHODS: Species identification was performed on 84 vaginal Candida isolates collected from October 2008 to June 2010 from 404 patients with suspected vulvovaginitis. MICs of C. albicans (26 isolates) to fluconazole, itraconazole, and voriconazole were tested by broth microdilution method of the Clinical and Laboratory Standards Institute (CLSI) M27-A2. RESULTS: C. albicans was the most frequently isolated (88.1%). All isolates were susceptible to fluconazole, itraconazole, and voriconazole. Trailing growth was found in treatment success group (10.0%) and treatment failure group (33.3%). CONCLUSIONS: The results of this study suggest the possibility that trailing growth have influence on treatment failure of vulvovaginal candidiasis.

BACKGROUND: Infectious vaginitis is caused primarily by three different groups of microbial pathogens (Trichomonas vaginalis, Candida spp., and Gardnerella vaginalis). The objective of this study was to compare the Affirm VPIII assay using a DNA hybridization technique with the Papanicolaou (Pap) smear test and the Gram stain in the detection and identification of these three organisms. METHODS: A total of 300 vaginal samples were collected from women that were either symptomatic for vaginitis or asymptomatic women that were being seen for routine obstetric or gynecological care. The presence of T. vaginalis, Candida spp., and G. vaginalis was evaluated by using the Affirm VIII assay (Becton Dickinson, USA), Pap smear test, and Gram stain method, respectively. RESULTS: With the Affirm VPIII assay, 1 (0.3%) patient tested positive for T. vaginalis, 99 (33.0%) patients were positive for G. vaginalis, and 18 (6.0%) were positive for Candida spp. The detection rates of Trichomonas infection, bacterial vaginosis and candidiasis by the Pap smear test and Gram stain method were 0.7% versus 0%, 16.3% versus 35.7%, and 1.7% versus 9.7%, respectively. The differences between the detection rates of the above three organisms between the Pap smear test and the Gram stain method were statistically significant (p<0.05). CONCLUSION: The Affirm VPIII assay was more sensitive than the Pap smear test and more specific than the Gram stain method for the detection and identification of these three organisms. In addition, the results of the Affirm VPIII assay are quick to obtain and are simple and easy to interpret.
