This study was undertaken to determine incidence, associated risk factors, and clinical outcomes of a diastasis of pubic symphysis. Among 4,151 women, who delivered 4,554 babies at the Department of Obstetrics of Seoul National University Bundang hospital from January 2004 to December 2006, eleven women were diagnosed as having a symptomatic diastasis of pubic symphysis. We estimated the incidence of the diastasis and identified the associated risk factors. To evaluate the pain relief and reduction of diastasis we followed up the 11 diastatic patients. The incidence of the diastasis was 1/385. Primiparity (P = 0.010) and twin gestation (P = 0.016) appeared as risk factors for diastasis by univairable analysis; and twin gestation appeared to be the only risk factor (P = 0.006) by logistic analysis. Two patients were operated due to intractable pain; and the remaining nine patients were treated conservatively. The diastatic gap decreased to less than 1.5 cm by 2 to 6 weeks after the diagnosis and then remained stationary. At a mean follow-up of 22.1 months (range, 12 to 47 months), five of 11 patients had persistent symphysis pubis dysfunction. Diastasis is more frequent than generally acknowledged. Pregnant women with multiple gestations should be informed about the potential risk of pubic symphysis diastasis.

PURPOSE: Anthropometry can be divided into two methods, direct anthropometry and indirect anthropometry. The most ideal and accurate method is a direct anthropometry. However, it is difficult to measure in the case of children because of poor cooperation, and it lacks re-productivity. Cast model has advantages of three dimensional featuring, inexpensive and easy fabrication. This study is conducted to find out an accuracy of indirect anthropometry on cast model by comparing it with direct anthropometry. METHODS: Total 48 cleft lip nasal deformity patients (unilateral, 40; bilateral, 8) were included in this study. Cast models were made before surgery under general anesthesia with alginate impression material and model plaster. Eleven linear measurements among 7 landmarks were taken as direct anthropometry before surgery with Castroviejo spreading caliper. At the same time, indirect anthropometry on cast model was done at the same linear distances as well. RESULTS: Of the total 11 linear measurements, both ala lengths, both columella lengths, nose width, projective distance between facial insertion points of the ala, projective distance between the alar base points, right nostril floor width, and columella width were statistically correlated between indirect anthropometry on cast model and direct anthropometry. However, the nasal tip protrusion and the left nostril floor width were not statistically correlated. CONCLUSION: Accuracy of indirect anthropometry on cast model can be influenced by cast model fabrication techniques and correct identification of landmarks. Nasal tip protrusion could be reduced by compression of the nasal tip in the process of cast model fabrication and nostril floor width can be varied by muscle relaxation of anesthetics and incorrect identification of subalare in cleft lip nasal deformity. If sufficient care is taken to make cast model and to define landmarks exactly, indirect anthropometry on cast model can be a reliable method as direct anthropometry.

PURPOSE: Adenoid cystic carcinoma is a rare type of eccrine sweat gland carcinoma. Although it is mostly known as a neoplasm of the salivary gland, it could occur as a primary skin tumor. We present a patient with a primary cutaneous adenoid cystic carcinoma at the genital area. METHODS: A 60-year-old man had a slowly growing 1 cm sized single tender mass near the left scrotum and he underwent excisional biopsy at a local clinic. A diagnosis of adenoid cystic carcinoma was made and thus he was transferred to our hospital. In physical examination, other specific findings were not detected except a linear scar caused by a previous skin biopsy near the left scrotum. In CT scan, PET-CT scan and endoscopy, there was no evidence of neoplasm in other organs. It was diagnosed as the primary cutaneous adenoid cystic carcinoma and then wide excisions were performed including total 4.5cm margin of normal skin. RESULTS: Microscopic findings revealed proliferation of tumor cell islands with cribriform or tubular patterns containing several round, pseudocystic structures. The tumor cells showed basaloid cells with uniform and small nuclei. Tumor cells infiltrated into the dermis and upper portion of subcutaneous tissue. There was multifocal perineural invasion of tumor cells. In postoperative 6 months, we found no recurrence and other complications. CONCLUSION: Herein we found a rare case of primary cutaneous adenoid cystic carcinoma at the genital area.

PURPOSE: The aim of this study was to evaluate changes in the bearing surface of an alumina head and cup insert after difficult intraoperative reduction of the head. MATERIALS AND METHODS: In two consecutive cases, where the force required for reduction caused scratching on the edge of the acetabular metal shell and marginal cracking of the adjacent portion of the alumina insert, the reduced alumina head was dislocated and retrieved with the alumina cup insert. The changes of the bearing surface were evaluated by gross inspection and by scanning electron microscopy(SEM) and energy dispersive x-ray spectrometry (EDAX). RESULTS: In both cases, the scratched area of the alumina head was found to have discolored. SEM and EDXA showed the discoloration to be the result of metallic debris from the titanium alloy shell. The metallic debris that was transferred from the head also stained the bearing surface of the alumina insert. CONCLUSION: Metallic debris might increase bearing surface wear. If the cracked ceramic fragments from the cup insert are neglected, it is also possible that they could be trapped between bearing surfaces and increase wear.

Purpose: We evaluated the results of cementless acetabular revisions performed with morselized bone grafting and screw-fixed hemispherical cups with different surface treatments. Materials and Methods: Forty hips, which had been followed for more than 10 years, were included in this study. Reconstruction was performed with 10 hydroxyapatite (HA)-coated cups and 30 porocoated ones. The mean followup time was 12 years and 1 months (range, 10 years to 15 years). Re-revision or radiographic loosening was considered as an endpoint of follow-up. Results: The average Harris hip score improved from 52 points to 75 points. During the follow-up period, radiographic loosening was observed in 17 hips. The loosened implants were HA-coated cups in 8 hips and porocoated ones in 9 hips. In 14 of these, re-revision of the cups was performed. The re-revision rate was 20% for the porocoated cups and 80% for the HA-coated cups. There were 2 hips with liner wear, which had undergone liner and head changes. Bone grafts were united in all the hips. The average time to union was 5.2 months (range, 2 to 9 months), and the average time to incorporation was 12 months (range, 5 to 18 months). Conclusion: Our results imply that HA-coated cups have a significantly higher failure rate compared with the porocoated ones (P<0.05) after a minimum follow-up of 10 years. Morselized bone grafting with use of a porocoated cup is an effective modality, which can restore the bone loss of the acetabulum in revision total hip arthroplasty.

We describe the case of a healthy young man with a femoral head fracture by low-energy trauma that occurred without evidence of hip dislocation. While plain radiographs showed no definite fracture or dislocation, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a femoral head fracture with a wedge-shaped cortical depression at the superomedial aspect of the femoral head. Our patient reported feeling that the right hip had been displaced from its joint for a moment. This probably represented subluxation with spontaneous relocation. The characteristic findings and possible mechanisms of this fracture were postulated on the basis of the sequential 3 dimensional-CT and MRI. The clinical results of conservative treatment were better than those of previously reported indentation fractures.

This study examined salivary flow and salivary pH and the prevalence and levels of cariogenic bacteria in the saliva of oncological patients and healthy controls. Quantitative real-time polymerase chain reaction was used to assess the levels of microbes including Streptococcus mutans, Streptococcus sobrinus, Lactobacillus salivarius, and Lactobacillus acidophilus in the saliva of 41 patients with a solid tumor (SO), 30 patients with a hematologic malignancy (HE), and 40 healthy controls. Salivary flow and pH were lower in oncological patients than in controls. The frequencies of all four cariogenic bacteria were highest in the SO group. S. mutans and L. salivarius were the most commonly detected in all three study groups. Mean numbers of S. sobrinus and L. salivarius in the SO group were significantly higher than in controls (p<0.05). There were no significant differences between patients and controls with respect to mean numbers of S. mutans and L. acidophilus in saliva. However, the proportions of S. mutans, S. sobrinus, and L. salivarius versus total bacteria in the SO group were significantly higher than in controls. Within patients, both mean numbers and the proportions of S. mutans and S. sobrinus were significantly different (p<0.05). In summary, significant differences were found in salivary pH values and the levels of S. mutans, S. sobrinus, and L. salivarius between SO patients and healthy controls.

BACKGROUND: To develop the guidelines and the education models for primary agents caring for victims of child abuse, and investigate victims of child abuse visited the department of emergency medicine, College of Medicine, Hallym University, Choon-chun Sacred Heart Hospital. METHODS: Survey assessed the age, sex, visiting time, offender tools of maltreatment, types of maltreatment, and types of injury of 47 victims under 18 years old visited the emergency center, between the Jul. 1996 and the Aug. 1998. The injury severiy of victims of child abuse was compared with control group of 197 general violence victims visited the same emergency center at the same duration. RESULTS: The age distribution was 12.8%(n=6) of the 0-1 year old, 17%(n=8) of the 1-3 years old, 8.5%(n=4) of the 4-6 years old, 12.8%(n=6) of the 7-12 years old, and 48.9%(n=23) of over the 13 years old. The sex distribution was 49%(n=23) of male and 51%(n=24) of female. The most common visiting time was 59.6%(n=28) of the 22-02 o'clock. The types of abuse were 46.6%(n=22) of the physical abuse, 27.7%(n=13) of the neglect, 17%(n=8) of the psychic abuse, and 8.5%(n=4) of the sexual abuse. The offender was 38%(n=18) of the parents, 26%(n=12) of the relatives, 4.3%(n=3) of the grandmothers, and 6.4%(n=3) of the nurses. The severity of injury was applied to the ISS(injury severity score). The severity of injury according to ISS was mean ISS=3.82+/- 2.2 in the case of child abuse and mean ISS=1.86+/-1.6 in the case of general violence(P=0.000). CONCLUSION: Most victims of child abuse still never come to the overt attention of physicians, social workers, or other professionals. Therefore the establishment of CAN(Child abuse and neglect) protocol and the organization of CAN team in the hospital consisted by department of emergency medicine, pediatrics, and psychiatrics is essential. Furthermore, the co-operation system with child welfare facilities and polices in community is needed.

BACKGROUND: Wear cannot be completely prevented after total hip arthroplasty. If severe polyethylene (PE) liner wear develops, the so-called catastrophic failure occurs and metallosis develops. We postulated that longevity of the new implant may be affected after revision surgery for metallosis following a catastrophic failure of a PE liner due to the substantial amount of PE wear particles and infiltration of the metal particles in this catastrophic condition. METHODS: Twenty-three hips of 23 patients were identified because they showed metallosis during revision total hip arthroplasties performed in Seoul National University Hospital between January 1996 and August 2004. They were followed for at least 6.5 years after the index revision total hip arthroplasty. The clinical and radiological results of revision total hip arthroplasties in these patients were evaluated. RESULTS: The median Harris hip score increased from 60 points before revision total hip arthroplasties to 90 points at the final follow-up. Osteolysis was detected at an average of 9.3 years after revision total hip arthroplasties in 13 hips and acetabular cup loosening at average 9.8 years after revision total hip arthroplasties in 9 hips. With radiographic evidence of osteolysis and loosening as the end points, the 15-year survival rates were 28.2% and 56.0%, respectively. CONCLUSIONS: The survival rate of revision total hip arthroplasty in patients with metallosis following a catastrophic failure of a PE liner was low.
