PURPOSE: Many articles have proposed that osteonecrosis of the femoral head (ONFH) is caused by fat embolism or intravascular coagulation linked to hyperlipidemia. To determine whether hyperlipidemia is an associated factor for ONFH, serum lipid levels were measured. MATERIALS AND METHODS: Nighty-eight patients presenting with ONFH and 110 controls were investigated. We compared the average value of serum lipid levels and the incidence of hyperlipidemia of the two groups. RESULTS: ONFH group showed generalized increase in lipid level and statistically significant difference in the average value of total cholesterol (P=0.0001), HDL-cholesterol (P=0.0261) and phospholipid (P=0.0465) compared with the control. The incidence of hyperlipidemia of the two groups showed statistically significant difference in HDL-cholesterol (P=0.019) and triglyceride (P=0.024). CONCLUSION: Hyperlipidemia seems to be associated with pathogenesis of ONFH. We speculated that hyperlipidemia might be a contributing factor of ONFH. Hyperlipidemia may play a role as a triggering factor in the pathogenetic process that results in osteonecrosis. However, it can not be ruled out that secondary hyperlipidemia might be a finding following ONFH.

Malacoplakia is an uncommon granulomatous inflammatory disease, which predomina- ntly affected the urinary tract, particularly the urinary bladder. The prostatic involve- ment of malacoplakia is extremely rare and may clinically mimic prostate cancer. A correct diagnosis of malacoplakia can be made by histopathologic findings characterized by accumulations of macrophages containing typical intracytoplasmic inclusions(Michael is-Gutmann bodies). We report a case of prostatic malacoplakia, which was incidentally found in prostate biopsy performed to confirm clinically suspected prostate cancer.

Sacral insufficiency fractures are unexpected causes of inguinal, lower back and buttock pain in elderly women with osteoporosis who have sustained unknown or only minimal trauma. Differential and radiological diagnoses of these fractures are often difficult. Bone scan remains the standard diagnostic tool, but computed tomography or magnetic resonance image may be required to differentiate insufficiency fracture from other diseases such as malignant bone lesion. The fracture usually extends vertically in the sacral ala, parallel to the sacroiliac joints. This distribution suggests that such fractures could be partially caused by weight-bearing transmitted through the spine. We report the treatment of insufficiency sacral fracture in one osteopenic patient who has been confirmed by computed tomography and treated with conservative method that convinced by follow up computed tomography.

Acute maxillary sinusitis is a common disorder affecting children. Untreated acute sinusitis can develop into chronic sinusitis, and complications, such as orbital cellulitis or abscess, can occur. Maxillary sinusitis of odontogenic origin is not a well-recognized condition and is frequently missed in children. As an odontogenic source of sinusitis, the dentigerous cyst is one of the most prevalent types of odontogenic cysts, and it is associated with the crown of an unerupted or developing tooth. This report concerns a nine-year-old boy who was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. The boy visited our pediatric clinic presenting with rhinorrhea and nasal obstruction and was initially diagnosed with maxillary sinusitis only. With antibiotic treatment, his symptoms seemed to improve, but after 2 months, he came to our clinic with left facial swelling with persistent rhinorrhea and nasal obstruction. Radiographic examinations of the sinuses were performed, and he was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. After a surgical procedure involving the removal of the dentigerous cyst with supernumerary teeth, the symptoms of sinusitis gradually diminished. There are only very few cases in the pediatric medical literature that remind us that odontogenic origin can cause maxillary sinusitis in children. Our patient can act as a reminder to general pediatricians to include dentigerous cysts in the differential diagnosis of maxillary sinusitis.

Cytomegalovirus(CMV) infections are common in immune compromised situations such as human immunodeficiency virus infection and organ transplantation. However CMV colitis had been rarely found in immunocompetent individuals. We experienced a case of an 83-year-old female patient, initially immune competent, who developed a massive lower gastrointestinal bleeding caused by CMV colitis. Previously, multiple antibiotics were used for nontuberculous Myco- bacterium and other bacterial infections after total knee arthroplasty. Colonoscopy revealed multiple ulcerations and mucosal congestion with hemorrhage. In spite of ganciclovir therapy, our patient did not recover.

A 58-year-old man with uncontrolled type 2 diabetes mellitus developed rhinocerebral mucormycosis. The infection progressed to intracranial extension despite more than 5 weeks of treatment with amphotericin B. The patient then received oral posaconazole, 800 mg/d, in divided doses for 6 months. Salvage treatment with the new azole antifungal posaconazole resulted in dramatic clinical improvement as early as 1 week after the initiation of therapy. Oral posaconazole continued through 24 weeks of treatment, with marked clinical, mycological, and radiological improvements and no adverse events. Here we review the medical literature on rhinocerebral mucormycosis, which is a rapidly progressive and often fatal infection. The treatment of choice is amphotericin B, which failed in our patient. Our case report suggests that posaconazole appears to be a well tolerated and effective salvage treatment option for rhinocerebral mucormycosis, including disseminated disease.

PURPOSE: We sought to elucidate the influence of acetazolamide on choroidal structure changes during the treatment of central serous chorioretinopathy (CSC).METHODS: This was a retrospective study of 45 eyes from 45 patients with acute CSC who were divided into an acetazolamide group (group 1, n = 20) and an observation group (group 2, n = 25). The main outcome measures were the changes in best-corrected visual acuity, subretinal fluid (SRF) height, subfoveal choroidal thickness (SFCT), and choroidal vascularity index (CVI) at one week, one month, two months, and three months, respectively.RESULTS: Although statistical significance was not reached, best-corrected visual acuity improved in both groups at month 3 (from 0.06 ± 0.07 to 0.01 ± 0.03 in group 1 and 0.17 ± 0.24 to 0.09 ± 0.18 in group 2; p = 0.083 and 0.183, respectively). Separately, SRF height and CVI showed a significant decrease at three months in both groups (all p < 0.05), while a significant SRF height decrease was also noted in group 1 at one month (p = 0.038). In group 1, a significant decrease in the SFCT and CVI started at one week and one month (p = 0.021 and 0.008), respectively. However, in group 2, a significant decrease in the SFCT and CVI started at one month and two months (p = 0.005 and 0.015), respectively.CONCLUSIONS: Acetazolamide has no effect on final functional or anatomical status at three months in eyes with CSC but does shorten the time for SRF absorption and accompanying choroidal structural changes.

BACKGROUND: Stent thrombosis and late restenosis are still major limitations in the clinical use of coronary stenting. Heparin-coated stent may reduce the incidences of stent thrombosis and restenosis. Heparin-coated stents were compared with control stents in a porcine coronary stent restenosis model in order to evaluate the effects of heparin-coated stent on stent restenosis. METHODS: Heparin was coated on a stent by deposition of an ultra-thin polymeric film containing amine groups by means of plasma polymerization. And then stent was immersed in heparin solution. Stent overdilation injury (stent:artery=1.3:1.0) was performed with bare (Group I, n=4) and heparin-coated (Group II, n=5) MAC stents in porcine coronary arteries. Follow-up quantitative coronary angiography (QCA) was performed at 4 weeks after stenting. The histopathologic assessments (KERN=*)of stented porcine coronary arteries were compared in between 2 groups. RESULTS: 1)Luminal area of stented artery was 7.05+/-1.25 mm2 in Group I and 7.67+/-2.85 mm2 in Group II, which were not different between two Groups. 2)Histopathologic stenosis of Group I was 35.7+/-13.2%, which was higher than 28.6+/-14.7% of Group II (p<0.05). Ratio of neointima/media was 1.16+/-0.52 in Group I and 0.87+/-0.31 in Group II and neointimal area was higher in Group I than in Group II (3.81+/-1.78 mm2 vs. 2.82+/-1.11 mm2, p<0.05 respectively). 3)PCNA (Proliferating cell nuclear antigen) index of GroupI was 10.0+/-2.2%, which was higher than in Group II (6.8+/-4.0%). CONCLUSIONS: Heparin-coated MAC stent may be effective in the inhibition of neointimal proliferation in a porcine stent restenosis model.

PURPOSE: This study was designed to determine the risk factors of lymph node (LN) metastasis in patients with submucosal invasive colorectal cancer (SICC). METHODS: Between January 1998 and January 2009, we reviewed patients who had undergone radical colon resection with LN dissection for SICC. RESULTS: There were 36 males and 40 females (mean age, 61.1 years; range, 35~86 years). In the univariate analysis, the risk of LN metastasis was related to the depth (absolute and relative), lymphovascular invasion, tumor budding, and tumor differentiation (P<0.05). The relative depth by Kudo classification and lymphovascular invasion were significant predictors of LN metastasis both in univariate and multivariate analysis. In SICC with an absolute depth <1,800 microm, no LN metastasis was detected. Regardless of the size of the SICC, tumors that invaded within the sm2 layer and had no lymphovascular invasion had no LN metastasis. CONCLUSION: In the SICC, lymphovascular invasion and depth of submucosal invasion are strong predictors of LN metastasis. If deep invasion exceeds sm2 and positive lymphovascular invasion exists in the resected specimen, additional colectomy with LN dissection appears to be necessary.
