Nine typical cases of ossifying fibroma in the tibia or fibula were retrospectively reviewed for clinical and histopathological aspects of this disease. Along with the case analysis, light and polarized microscopic examinations were performed in each case. Differential points with monostotic fibrous dysplasia were as follows; 1) ossifying fibroma begins in the significantly younger age, which is in most cases below 10 years of age, 2) it is confined to diaphysis of tibia or fibula, 3) radiologically, multilocular osteolytic destructive change in eccentric pattern is usually combined with anterior or anterolateral bowing deformity, 4) microscopically, characteristic findings are presence of osteoblastic rimming, peripheral maturation, and zonal phenomenon. In the treatment of ossifying fibroma, definitive surgical treatment should be delayed until skeletal maturity, when segmental resection in wide margin including periosteum might be preferred.

BACKGROUND: Recently, the molecular pathologic investigation for clonality in lymphomas has been introduced and has gained a role in the diagnosis of lymphomas. In fact, the clonality test using TCRGR phenomenon has been done by Southern blot analysis (SBA) and polymerase chain reaction (PCR) for molecular pathologic diagnosis of T cell lymphomas. However, it is difficult to perform SBA with paraffin embedded specimens or with samples of small skin biopsies. OBJECTIVE: We investigated the efficacy of PCR amplification of TCR gene in paraffin em-bedded cutaneous T cell lymphomas. METHODS: Iii this study, the clonality was assessed by polymerase chain reaction (PCR) analysis of T cell receptor gamma (TCR) gene from the DNA extracts obtained from paraffin em-bedded tissues (PET) of malignant T cells, B cell lymphomas, and benign cutaneous T cell proliferative disorders. Heteroduple-x-analyses were also performed to rule out the false positives. RESULTS: Among the total of 62 cases analyzed, monoclonality was observed in 4 out of 10 mycosis fungoides, 7 out of 9 cutaneous T cell lymphomas excluding mycosis fungoides, 1 out of 3 angiocentric lymphomas, 2 out of 2 lymphomatosis papulosis, 1 out of 7 large plaque parapsoriasis, and 1 out of 2 T cell lymphomas in other organs. No monoclonality was observed in 9 inflammatory cutaneous diseases, 5 small plaque parapsoriasis, 4 cutaneous B cell lymphomas, and 11 B cell lymphomas in lymph nodes. CONCLUSION: The results suggest that the PCR method and heteroduplex analysis used in this study were not only practical but also efficacious for the diagnosis of cutaneous T cell lymphomas using tissues embedded in paraffins.

Cowden syndrome (CS), also known as multiple hamartomas syndrome, is a rare hereditary autosomal dominant disorder caused by a germline mutation in the phosphatase and tensin homolog (PTEN) gene mapped on chromosome 10. The clinical features of CS are variable, primarily presenting as mucocutaneous lesions (99%). A mucocutaneous lesion, such as trichilemmoma of the face or keratosis of the extremities, is an important diagnostic marker for CS. CS has been reported to increase the incidence of benign and malignant neoplasms in the breast, thyroid, and gastrointestinal tract. The risk of developing malignancy in individuals with CS is up to 10 times higher than general population throughout an entire life time.

The causes of hip pain are variable, and, due to its size and deep position, complete physical examination is often difficult. In the past, ultrasonography (US) for the hip was mainly performed in order to rule out developmental hip dysplasia in infants or for evaluation of joint effusion. Now, however, US of the hip has been widely accepted as a useful modality in patients with hip pain and is commonly used in both adults and children. Joint effusion, bursitis, tendinosis or tendon tear, and acetabular labral tear can be main targets. Dynamic study for snapping hip is another unique advantage of US. In addition, US is very useful for guided procedures - aspiration, biopsy, or injection. In this review, the authors will discuss US findings of these common lesions with a brief review of anatomy.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) strategy is proposed to reduce the ventilator-induced lung injury in acute respiratory distress syndrome (ARDS). As ECMO use has increased, a number of studies on prognostic factors have been published. Age is estimated to be an important prognostic factor. However, clinical evidences about ECMO use in elderly patients are limited. Therefore, we investigated clinical courses and outcomes of ECMO in elderly patients with ARDS. METHODS: We reviewed medical records of patients with severe ARDS who required ECMO support. Study patients were classified into an elderly group (> or = 65 years) and a non-elderly group (< 65 years). Baseline characteristics, ECMO related outcomes and associated factors were retrospectively analyzed according to group. RESULTS: From February 2011 to June 2013, a total of 31 patients with severe ARDS were treated with ECMO. Overall, 14 (45.2%) were weaned from ECMO, 9 (29.0%) survived to the general ward and 7 (22.6%) survived to discharge. Among the 18 elderly group patients, 7 (38.9%) were weaned from ECMO, 4 (22.2%) were survived to the general ward and 2 (11.1%) were survived to discharge. Overall intensive care unit survival was inversely correlated with concomitant acute kidney injury or septic shock. CONCLUSIONS: In this study, ECMO outcome was poor in severe ARDS patients aged over 65 years. Therefore, the routine use of ECMO in elderly patients with severe ARDS is not warranted except in highly selective cases.

PURPOSE: Ibuprofen is used for prevention and treatment of patent ductus arteriosus as an alternative drug of indomethacin in very premature infants. We aimed to determine the effect of prophylactic ibuprofen on patent ductus arteriosus and clinical outcomes in preterm infants less than 1,250 g. METHODS: A retrospective review of 39 preterm infants who were admitted to our neonatal intensive care unit from November 2009 to July 2010 was performed. Patients were divided into a prophylactic group (n=13) and a matched historical control group (n=26), where prophylactic ibuprofen were administrated within 24 hours after birth. The rate of ductal closure, side-effects of drug treatment and clinical outcomes were compared between two groups. RESULTS: Comparison of the prophylactic and control groups revealed no significant differences in the rate of ductal closure (69.2% vs 77.7%, P=0.825) and surgical ligation (23.1% vs 30.8%, P=0.719). Occurrence of bowel perforation was more frequent in the prophylactic group than the control group, but was not significant (30.8% vs 11.5%, P=0.194). The frequency of intraventricular hemorrhage (grade> or =3) and other outcomes did not differ between the groups. CONCLUSION: Ibuprofen prophylaxis in preterm infants did not decrease the rate of ductal closure, the need for surgical ligation and the incidence of intraventricular hemorrhage. Further studies are needed to investigate the beneficial effect and associated adverse events attributed to ibuprofen prophylaxis.

BACKGROUND: Procalcitonin (PCT) is a relatively new marker for bacterial infections, and its diagnostic utility has been variable across the studies. We investigated the diagnostic utility of PCT for the patients with blood culture-positive sepsis, and compared it with that of C-reactive protein (CRP). METHODS: In 1,270 consecutive blood samples, PCT and CRP were simultaneously measured and results were compared according to the five categories of PCT concentrations (<0.05 ng/mL; 0.05-0.49 ng/mL; 0.5-1.99 ng/mL; 2-9.99 ng/mL; > or =10 ng/mL). In 506 samples, they were further analyzed according to the result of blood culture. PCT and CRP were measured using enzyme-linked fluorescent assay (bioMerieux Co., France) and rate nephelometry (Beckman Coulter Co., USA), respectively. Their diagnostic utilities were compared using ROC curves. RESULTS: The mean concentrations of CRP in five categories of PCT were 15.4 mg/L, 42.1 mg/L, 101.2 mg/L, 125.0 mg/L, 167.1 mg/L, respectively (P<0.0001). Both PCT and CRP showed significant differences between the two positive and negative groups of blood culture (PCT, 8.47 vs 2.44 ng/mL, P=0.0133; CRP, 110.48 vs 59.78 mg/L, P<0.0001). The areas under the ROC curves (95% confidence interval) for PCT and CRP were 0.720 (0.644-0.788) and 0.558 (0.478-0.636), respectively, and showed a significant difference (P=0.005). CONCLUSIONS: The diagnostic utility of PCT is superior to that of CRP for the patients with blood culture-positive sepsis. PCT seems to be reliable for sepsis diagnosis, and may provide useful information for the critically ill patients.

PURPOSE: Conflicting results have been reported for western populations on associations of serum insulin-like growth factor I (IGF-I) and major IGF-binding protein-3 (IGFBP-3) with the risk of prostate cancer. However, few data have been available for oriental populations. We undertook a matched case-control study in a low-risk Korean population to extend our knowledge about potential associations. MATERIALS AND METHODS: Serum IGF-I and IGFBP-3 levels were determined for 330 men (165 cases and 165 healthy age-matched controls). Conditional logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for the association between plasma IGF levels and prostate cancer. We also investigated the potential influence of the associations according to clinical risk for advanced disease at diagnosis. RESULTS: We noted that the risks of prostate cancer were unrelated to the IGF-1 level and IGF-I/IGFBP-3 molar ratio. In contrast, a strong inverse association was observed between IGFBP-3 levels and the risk for prostate cancer. Men in the highest quartile of IGFBP-3 levels had a 71% reduced risk of prostate cancer compared with men in the lowest quartile (OR=0.29, 95% CI: 0.11-0.64, P(trend)<0.001). Subgroup analysis revealed a significant inverse association between plasma IGFBP-3 and the likelihood of a high risk prostate cancer. CONCLUSIONS: Plasma IGFBP-3 levels were inversely associated with the risk of prostate cancer and the likelihood for high-risk disease, suggesting that IGFBP-3 plays a protective role against prostate cancer in the Korean population.

This is a retrospective study on condylar fracture of mandible. The stucy based on a series of 112 patients who had treated for the fractures of mandibular condyle on Kyunghee Dental Hospital from January, 1989 to August 1997. We studied the age and sex distributions, causes of fractures, location of fractures and so on. The results as follow : 1. The ratio of male : female was 4:1, and the highest frequency of condylar fractures was registered among patients aged to 21 to 30 years. 2. The most common cause of condylar fractures was fall-down(47.7%), followed in incidence by direct-blow(27.9%) and traffic accidents(20.7%). 3. Subcondylar fracture had highest incidence(50%), and followed by condyle head(27.4%) and condylar neck(22.6%). 4. 9.7% of condylar fractures had occurred bilaterally and in cases of bilateral condylar fractures, condylar head fractures(58.33%) was hightest incidence. 5. Mandibular symphysis was most commonly involved in condylar fracture(63.4%), and 27.7% of condylar fractures had not any other mandibular fractures.

Williams syndrome, initially described by Williams et al. in 1961 is associated with characteristic dysmorphic features, congenital heart disease, distinctive behavior, and emotional traits. Sudden death has been reported perioperatively due to congenital heart disease in patients suffering from Williams syndrome. We present a case of a patient with Williams syndrome underwent preauricular fistulectomy and medial rectus recession. Airway management and tracheal intubation were successfully performed on the patient. For anesthetic management, sevoflurane and vecuronium, as well as sevoflurane and rocuronium were employed during the first and second operation, respectively. Anesthetic managements were performed uneventfully in this patient.
