PURPOSE: Septic arthritis of the knee is a relative rare complication of the arthroscopic anterior cruciate ligament reconstruction, but inadequate treatment of this complication may lead to a devastating conse- quence of a chronic infection. Moreover, no guidelines have been proposed for the treatment of patients with knee infections after the anterior cruciate ligament reconstruction. To determine the optimal diagno- sis and treatment recommendation, we performed this study. MATERIALS AND METHODS: We performed retrospective study of the knee joint infections after the arthroscopic anterior cruciate ligament reconstruction between August 1993 and August 1998, Of the 420 patients who reviewed arthroscopic ACL reconstruction during this period from one surgeon, we experi- enced 4 cases(0.95%) of postoperative deep infections of the knee. RESULTS: All 4 patients were male, and the average age was 32 years(range from 19 to 43). Two patients had acute(< 2 weeks), two patients had subacute infections(2 weeks to 2 months). The acute cases had more severe symptoms, and positive cultures from knee joint aspirates. All patients underwent immediate open(1 case), or arthroscopic irrigation and debridement. One patient underwent repeat irriga- tion and debridement. The graft was removed from all patients in acute cases. CONCLUSION: The clinical symptoms, and the infected organism were more helpful than the peripheral blood counts in the diagnosis of a deep infection of the knee. Arthroscopic lavage, and debridement com- bined with intravenous antibiotics were effective treatment options. Clinical symptoms were more severe in acute cases, and early graft removal is an adequate method of surgical treatment.

The treatment of acutely torn anterior cruciate ligament(A.C.L) remains a controversial subject. The purpose of this paper is to show the arthroscopic technique of A.C.L. primary repair with or without augmentation with semitendinosus tendon. Twenty-one patients with acute A.C.L. tear were treated with repair or augmented repair under arthroscopic control from April 1989 to August 1993. Five A.C.L. torn at femoral attachment with intact distal stump were treated with arthoscopic repair alone & 16 A.C.L. torn at substance near the femoral attachment with arthroscopic repair & augmentation with semitendinosus tendon. The patient population included of 16 males and 5 females with an average age 28.3 years. Fifteen patients injuried during sports activity. Postoperative results were evaluated by Lysholm knee score & Hospital for Special Surgery knee scale in average 26 months (range from 12 months to 64 months). All patients were rated as good or excellent result except one patient who had fair result. At follow-up study, testing with KT1000 arthrometer revealed 17 patients had less than 3mm of side to side difference. Second look arthroscopy was performed in 15 patients from 4 to 29 months after repair or augmented repair. Eleven out of these 15 A.C.L. were well healed with good tension 8r. revascularization of graft. Remaining 4 A.C.L. were healed with scar tissue. On the based of this study, arthroscopic repair or augmented repair is very effective treatment for acutely torn A.C.L. near the femoral attachment.

We reviewed 24 patients who had performed arthroscopic meniscal repair for the treatment off discoid lateral meniscal tear between january 1989 and December 1992. The follow up ranged from 1 year 6 month to 4 year 6 month(average 32month). The mean age was 17.9(range,8-50)years, the patients under 20 years old were 17(cases,71%).Common preoperative clinical symptom was pain on the knee joint(21 cases,87.5%) and click(19 cases,79%).Positive McMurry test was the most common physical examination finding(19 cases, 79%). All the lateral discoid meniscal tears were confirmed by arthroscopy. The mean interval between symptom onset and operation was 18.7 months(range 1 month to 10 year). The types of tear were peripheral (14cases, 58%), complex tear(4cases), longitudinal tear(2cases), transverse tear(2cases), horizontal tear(2cases)and the most common location of tear was posterior horn(1 1cases, 45%). The mean number of suture was four. In operative method, Scases(33%) were performed only meniscorrhaphy and meniscorrhaphy combined with partial meniscectomy was done in 16 cases(67%). According to Ikeuchi's grading system, the result was satisfactory in 21cases, fair in three cases. Second look arthroscopy was done in eleven cases(46%) between post operative 4 months to 2 years(mean, 8.3 months). The arthroscopic examination revealed complete healing of repaired meniscus in eight cases(73%). The remained three cases which were not completely healed was fair result.

PURPOSE: As the number of children who attend child care centers has increased, concerns has increased about the effect of child day care on childhood illness. This study was conducted to examine the relationship between experience in child care and common infectious diseases in children under 5 years of age. METHODS: Data were collected by surveying 1,000 respondents with children under age 5 through online interviews using a structured questionnaire. The contents of the survey were composed of demographic characteristics, child care facilities usage, experience in infectious diseases, and immunization status. RESULTS: Among the 1,000 children <5 years of age, 78.5% attended a child care facility. Rates of common communicable illnesses were higher in children in child care than for children reared exclusively at home. The predominant communicable diseases which the respondents' children experienced, in order of decreasing frequency, were gastroenteritis (47.1%), otitis media (41.8%) and pneumonia (19.1%). The immunization rate of vaccines that are not included the national immunization program (NIP) (Haemophilus influenzae type b vaccine - 76.6%, hepatitis A vaccine - 63.3%, pneumococcal vaccine - 59.4%, rotavirus vaccine - 43.1%) was lower than that of the NIP vaccines (90.4%). CONCLUSION: Children in child care experience more bouts of common infectious disease, so nationwide policies to prevent or to control the spread of infectious agents in a child-care should be available and appropriate immunization should be emphasized as the most effective method for the control of infectious disease for children.

PURPOSE: The aim of this study was to determine the frequency, epidemiology and the clinical manifestation of human metapneumovirus (hMPV) infection in Korean children. METHODS: From February 2010 to January 2012, we collected nasopharyngeal aspiration from 1,554 children who were hospitalized for acute lower respiratory tract infections at the Department of Pediatrics, Severance Children's Hospital. hMPV was detected by performing reverse transcriptase-polymerase chain reaction (RT-PCR). The medical records of the patients with positive results were retrospectively reviewed. RESULTS: We detected hMPV in 99 of the 1,554 hospitalized children. The mean age of the hMPV infected children was 25 months, and 87% of the illnesses occurred between April and June. The most common diagnoses were pneumonia (73%) and bronchiolitis (16%). The clinical manifestations included cough, fever, respiratory distress, hoarseness, tachypnea, and wheezing. Coinfection with other respiratory viruses was found in 43 children (43%). CONCLUSION: hMPV is one of the major virus causing acute respiratory tract infection in the age between 13 months and 48 months old with peaks during April to June. Reports of hMPV in Korea has been increasing but additional studies are required to define the epidemiology and the extent of disease caused by hMPV to determine future development of this illness in Korean children.

Cerebral infarction in the territory of the paramedian thalamopeduncular artery (PTA) causes various lesions in the upper midbrain and thalamus resulting in widespread disturbances in neurological function. However, the exact topography and variations in the territories of the PTA remain unknown. We report four patients with MRI-proven infarctions in the PTA territory. One patient had lesions in the unilateral thalamus and midbrain, the other two had lesions in the bilateral paramedian thalamus and unilateral midbrain, and the remaining patient had lesions in the unilateral thalamus and bilateral midbrain. Clinical manifestations depended on the variations of the size and extent of infarctions. Theanatomical variations of the PTA are discussed and suggested.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances. This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.
