RESUMEN
BACKGROUND: The purpose of this study is to report a modified transtibial technique to approach the center of anatomical femoral footprint in anterior cruciate ligament (ACL) reconstruction and to investigate the accurate femoral tunnel position with 3-dimensional computed tomography (3D-CT) and radiography after reconstruction. METHODS: From December 2010 to October 2011, we evaluated 98 patients who underwent primary ACL reconstruction using a modified transtibial technique to approach the center of anatomical femoral footprint in single bundle ACL reconstruction with hamstring autograft. Their femoral tunnel positions were investigated with 3D-CT and radiography postoperatively. Femoral tunnel angle was measured on the postoperative anteroposterior (AP) radiograph and the center of the femoral tunnel aperture on the lateral femoral condyle was assessed with 3D-CT according to the quadrant method by two orthopedic surgeons. RESULTS: According to the quadrant method with 3D-CT, the femoral tunnel was measured at a mean of 32.94% +/- 5.16% from the proximal condylar surface (parallel to the Blumensaat line) and 41.89% +/- 5.58% from the notch roof (perpendicular to the Blumensaat line) with good interobserver (intraclass correlation coefficients [ICC], 0.766 and 0.793, respectively) and intraobserver reliability (ICC, 0.875 and 0.893, respectively). According to the radiographic measurement on the AP view, the femoral tunnel angles averaged 50.43degrees +/- 7.04degrees (ICC, 0.783 and 0.911, respectively). CONCLUSIONS: Our modified transtibial technique is anticipated to provide more anatomical placement of the femoral tunnel during ACL reconstruction than the former traditional transtibial techniques.

When faced with an irrepairable meniscus or a patient who has had a total or subtotal meniscectomy, meniscus allograft transplantation (MAT) is the preferred modality to restore biomechanical function of the meniscus. The indications for meniscus allograft transplantation are yet to be established. However, currently, MAT has previously been indicated for symptomatic patients who have mild or early osteoarthritis, are younger than 50 years of age, and present with an Outerbridge grade II or lower. The short- to intermediate-term results confirmed noteworthy clinical improvements and consistent objective findings. On the other hand, the successful outcome would be reduced by various complications. Therefore, long-term observation required to evaluate the longevity of these results. The purpose of this article is to review the current research of concerns on the results of MAT, and to describe the technical tips and pitfalls so as to successful clinical results.

Bell's palsy is an idiopathic peripheral facial nerve palsy of acute onset. Although some studies have reported cases of Bell's palsy after certain vaccinations, reports of Bell's palsy in association with diphtheria-tetanus-acellular pertussis (DTaP) and inactivated poliomyelitis vaccination (IPV) have been rare. Here, we report two infants who suffered from Bell's palsy after immunization with DTaP and IPV and recovered completely without neurologic deficits.

Congenital combined deficiency of vitamin K dependent coagulation factors is a rare coagulation disorder. We experienced a 20-month old boy who was found to have a congenital vitamin K dependent coagulation factor defeciency. He presented with continuous bleeding on lacerated hard palate and had a history of numerous hemorrhagic episodes with multiple bruises after birth. Laboratory finding showed prolonged prothrombin time and partial thromboplastin time. Blood coagulation work-up showed marked decreased activities of the coagulation factors II, VII, IX, X and the natural anticoagulants proteins C and S. Assay of coagulation factors in the parents and sibling were with the normal range. There's no evidence of malabsorption, liver disease or ingestion of a coumarin compound. Response to intravenous administration of vitamin K1 was not significant but transfusion of fresh frozen plasma corrected prothrombin time and partial thromboplastin time. We reported a case of congenital combined deficiency of vitamin K dependent coagulation factors.

PURPOSE: Intractable diarrhea during infancy is one of the major causes of infant mortality. But, its etiology, clinical courses, or methods of treatment are not well known. Therefore, we conducted a clinical approach to intractable diarrhea during infancy. METHODS: We have retrospectively evaluated clinical characteristics, laboratory findings, methods of treatment, days required for recovery, in 23 infants who were admitted with intractable diarrhea, from January 1993 to December 1996. RESULTS: The onset age was 18.4 +/- 17.8 days and the duration of diarrhea was 28.8 +/- 16.5 days. All patients were fed artificial milk before the onset of diarrhea. The possible causes of diarrhea were infection (60.8%), change of milk, milk concentration (17.4%), or an unknown origin (21.8%). Laboratory findings on admission showed hemoglobin 9.5 +/- 2.2g/dL, serum albumin 2.9 +/- 0.7g/dL. E. coli was cultured in urine in 1 case. Stool rotavirus antibody was positive in 1 case. Nineteen patients (82.6%) required total parenteral nutrition for 18.3 +/- 13.6 days and antibiotics were administered to 20 patients (86.9%). Twenty-two patients (95.7%) were fed special element formula milk. All but one who died of necrotizing enterocolitis, recovered. Special element fomula milk was used for 92.6 +/- 20.5 days after discharge, and there were no cases of recurrence. CONCLUSION: We considered appropriate oral element fomulas, total parenteral nutrition and the proper treatment of infection as important factors in future outcome of intractable diarrhea during infancy. We thought the short-term administration of special formula milk can be substituted for normal milk or a weaning diet. However, encouraging breast feeding may perhaps be a more effective way of preventing this problem.
