Significant traumatic disruption of the ligaments about the knee can occur in a child. Recently several reports have described knee ligament, injuries with open growth plates. And these reports contradict the notion that complete tears of knee ligaments occur only after growth plates have closed. The youngest patient with medial collateral ligament injury reported before was a 4-year-old boy by Joseph and Pogrund in 1978. But authors experienced a case of ruptured medial collateral ligament of the knee in a 2-year and 1-month old boy, who seemed to be youngest with the ligament injury.

MR imaging was performed in 40 patients of aortic disease from March 1988 to February 1990. Transverse, coronal and oblique sagital views were obtained with ECG gating and even echo technique using 0.5 T and 2.0 T MR systems. In 12 patients of aortic aneurysm, the location, the size and the extent of aneurysm could be assessed in all cases. In the cases of six abdominal aortic aneurysm, the relation of aneurysm to renal arteries was evaluated. In 18 cases of aortic dissection, the extent of involvement as well as associated abnormalities was well evaluated in all cases. In the 8 cases of congenital aortic anomalies, the vascular anatomy was well demonstrated. However, the abnormalities of major branches could not be assessed with MR imaging especially in 2 cases of Takayasu's arteritis. With our experiences, MR imaging is regarded as a primary diagnostic modality for aortic disease and expected to be developed as the alternative measure to the angiography in the future.

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

BACKGROUND/AIMS: With the development of self-expanding metallic stents, colonic obstruction can be relieved without the need for surgery. The results of preoperative placement of stents for malignant colorectal obstruction might be different according to the obstructing lesion. The objective of this study was to compare clinical improvement rates and operative results after preoperative placement of stents for malignant colorectal obstruction according to the location of the obstructing lesion. METHODS: This is a retrospective study including 57 patients who underwent self-expanding metallic stent insertion for obstructing resectable colorectal cancers. Patients were classified into three groups according to the location of the lesion as follows: proximal to the sigmoid colon (Group A), sigmoid colon (Group B), and rectum (Group C). RESULTS: The number of patients in A, B, and C groups was 13, 22, and 22, respectively. No significant differences in age, gender, stent type, and accompanying diseases among the three groups were observed. There were no significant differences in stent-related complications, clinical improvement rates, and one-stage resection rates among the three groups. The postoperative complications, the requirement rate of ICU care, the period of ICU stay, postoperative hospital stay, and hospital mortality did not significantly differ among the three groups. CONCLUSIONS: Clinical improvement rates and operative results after successful placement of stents for obstructing resectable colorectal cancers are not different according to the location of the obstructing lesion, suggesting that preoperative stenting for one-stage curative resection is useful, irrespective of the location of lesion.

PURPOSE: To compare postoperative vision, high-order aberrations, contrast sensitivity, power of accommodation, and depth of focus of monofocal aspheric (TECNIS ZA9003) and multifocal aspheric (TECNIS ZM900) intraocular lenses (IOL). METHODS: Thirty-four eyes which received intraocular lens implantation in the posterior chamber were equally divided into two groups: TECNIS ZA9003 (17 eyes) and TECNIS ZM900 (17 eyes). Before and three months after surgery, visual acuities at near, intermediate, and far distances, and depth of focus were recorded. High order aberrations, spherical aberrations and accommodation power were measured with iTrace, and contrast sensitivity was evaluated using Optec 6500. An independent T-test analysis was used to compare the two groups. RESULTS: There were no significant differences of high order aberrations, spherical aberrations, accommodation power, or distance vision between the two groups at three months postoperatively. The multifocal IOL (TECNIS ZM900) group revealed better intermediate and near vision (p<0.01) and deeper depth of focus, and lower contrast sensitivities (p=0.03) than the monofocal IOL group. CONCLUSIONS: There was no difference in accommodation power between the two groups, but multifocal TECNIS ZM900 IOL exceeds monofocal TECNIS ZA9003 IOL in intermediate and near vision due to diffractive lens design and less spherical aberration by its asphericity.

OBJECTIVES: The purpose of this study was to evaluate the efficacy of a 2.9% hydrogen peroxide (HP) whitening strip with a desensitizing agent as a primer. METHODS: This study was approved by the Institutional Review Board of Kyungpook National University Hospital. A total of 144 subjects (mean age: 21.7 years) were recruited after they provided informed consent for participation in the study. All participants used the whitening strip and primer for 1.5 h a day for 14 days. ShadeEye-NCC and Vita classical shade guide were used to determine the color changes, with respect to baseline, after 1, 3, 5, 7, and 14 days. A self-administered questionnaire was used to collect data on satisfaction after bleaching and irritating symptoms during the 14 days. All collected data were analyzed with repeated measures ANOVA and one-way ANOVA using SPSS 20.0 for windows. RESULTS: Brightness (ΔL*) was significantly higher in groups 2 and 3 than in the control group after 3 days of the experiment. Chroma (Δb*) started to decrease in groups 2 and 3, compared to control, after 1 day. Perceived symptoms of irritation were significantly lower in groups using the strip combined with the desensitizing primer than in the control group. Satisfaction after bleaching was higher in the experimental groups than in control. CONCLUSIONS: The HP whitening strip with a desensitizing agent as a primer is clinically effective in bleaching human enamel after 3 days of use. It also reduces the prevalence of gingival irritation.

The gastrointestinal tract is commonly involved in patients with systemic sclerosis. The manifestations include motility disorder, pseudo-obstruction, malabsorption, bacterial overgrowth, diverticuli, and, less commonly, pneumatosis cystoides intestinalis (PCI). PCI is characterized by the presence of air in the submucosal or subserosal layer of the bowel wall and is often accompanied by pneumoperitoneum. Although PCI is a benign condition that often responds to conservative management, it is a poor prognostic factor of systemic sclerosis. We report a case of PCI in a patient with systemic sclerosis. The chest and abdominal radiographic findings comprised pneumoperitoneum, marked dilation of the bowels, and intramural air, compatible with PCI. The patient's symptoms improved spontaneously. It is important to recognize PCI as a gastrointestinal manifestation of systemic sclerosis, and physicians should differentiate it from serious complications-such as intestinal perforation-based on clinical manifestations.

PURPOSE: This study was conducted to evaluate the effect and usefulness of cervical selective nerve root block in advance for the patients who was scheduled for operation. MATERIALS AND METHODS: Between January 2001 to December 2008, 28 cases were selected from the patients, who underwent selective nerve root block before operation. The mean follow-up period was 30.4 months and the mean age was 59.2 years. The patients were divided into the operation group and the only cervical nerve root block group. The groups were compared for age, gender, the contraction period and the, solidity of the disc. The groups were radiologically evaluated for the existence of cervical spondylosis and the neural compression rate. The clinical results were analyzed using the neck disability index (NDI) and the visual analogue scale (VAS) score. RESULTS: Among the 28 cases that were scheduled for operation, 18 cases did not proceed to operation and 10 cases among them were treated with additional conservative treatment. The average VAS score for the operation group and the cervical nerve root block group was 8.3 and 7.7 at the preoperative state and the preinjection state, respectively. After surgical treatment and cervical nerve root block, the scores were 3.2 and 3.6, respectively. The NDI for the operation group was 40.6 at the preoperative state and this decreased to 11.2 at the last follow up. The NDI for the cervical nerve root block group was 38.4 at the preinjection state and this decreased to 13.6 at the last follow up. The mean contraction period was 3.2 months and the mean age was 51.9 years for the operative group. The mean contraction period was 14.82 months and the mean age was 55.9 years for the root block group. There was no difference of clinical outcomes between the operative group and the cervical nerve root block group. The operation group's mean age was younger and the duration of symptom was shorter than those of the cervical nerve root block group. CONCLUSION: Cervical nerve root block is considered to be an effective treatment for patients with cervical disc herniation with radiating pain and who are scheduled for an operation.

BACKGROUND AND OBJECTIVES: The purpose of this study was to share our clinical experience on the use of bioresorbable poly L-/DL-lactide 70/30 implant to repair blow out fracture. SUBJECTS AND METHOD: The medical records of 130 patients with orbital fractures that were treated surgically from June 2006 to February 2011 were reviewed retrospectively. Patients who had diplopia or limited extraocular motion, significant Enophthalmos (>2 mm), or a large orbital wall fracture on a computed tomographic scan were enrolled for the study. We investigated diplopia, limited extraoacular motion, enophthalmos before and after surgery. RESULTS: The mean postoperative follow-up was 28 months. There was no evidence of sinus infection related to the implant. However, six patients showed dislocation of orbital implant in the nasal cavity. After six postoperative months, diplopia was seen in 1 (2%) patient, and significant enophthalmos was seen 2 (2%) patients. We carried out re-operation on six cases and the main cause was incomplete reduction or over reduction. CONCLUSION: Bioresorbable poly L-/DL-lactide 70/30 implants are safe and reliable for the reduction for blowout fracture.

Background: The association of invasive tracheobronchial aspergillosis (ITBA) with invasive pulmonary aspergillosis (IPA) is not well established. We aimed to compare clinical characteristics between patients who exhibited ITBA with IPA and those who exhibited isolated ITBA (iITBA). Additionally, the usefulness of serum or bronchial galactomannan (GM) tests in diagnosing ITBA was evaluated. Methods: This retrospective single-center case-control study was conducted over a period of 4 years. Fifteen patients were enrolled after confirming the presence of ITBA using bronchoscopy-guided biopsy (iITBA, 7 vs. ITBA+IPA, 8). Clinical characteristics of patients and results obtained from serum or bronchial GM tests were compared between the two groups. Mortality was assessed using data collected from a 6-month follow-up period. Results: The ITBA+IPA group showed a higher prevalence of hematologic malignancy (75% vs. 14%, p=0.029), a greater number of patients with multiple bronchial ulcers (75% vs. 14%, p=0.029), lower platelet counts (63,000/μL vs. 229,000/μL, p<0.001), and a mortality rate which was significantly higher (63% vs. 0%, p=0.026) than the iITBA group. In the ITBA+IPA group, 57% of patients tested positive according to the serum GM assay, whereas in the iITBA group, all patients tested negative (p=0.070). The bronchial GM level was high in both groups, but there was no significant difference between them. Conclusion Patients with ITBA+IPA had a greater number of hematologic malignancies with lower platelet counts and a poorer prognosis than patients diagnosed with iITBA. Findings obtained from bronchoscopy and bronchial GM tests were more useful in diagnosing ITBA than the serum GM test results.
