PURPOSE: This study was designed to evaluate characteristics of foot pressure distribution with or without partial prosthetic foot in transmetatarsal amputee. MATERIALS AND METHODS: The subjects were 9 transmetatarsal amputees. Foot pressures were measured at hallux, the 1st-5th metatarsal head (MTH), mid-foot, condyle area by F-scan system in amputated or contralateral foot during active walking. RESULTS: In amputated foot, mean peak pressure was greatest in midfoot without prosthetic foot but it was greatest in hindfoot with prosthetic foot. In unaffected foot, although mean peak pressure was higher in hallux, and 1-5th MTH compared to amputated foot, it was greatest in hind foot both with and without prosthetic foot. However, in unaffected foot, mean peak pressure significantly decreased in hallux and 5th MTH after wearing the prosthetic foot. There was a significant difference in mean peak pressure in hallux and 5th MTH between amputated and unaffected foot after wearing prosthetic foot. However, other region had no significant difference with or without prosthetic foot between feet. CONCLUSIONS: The use of partial prosthetic foot tends to shift weight bearing from the heel area to forefoot and could significantly reduce hind foot peak pressure and redistributed to peak pressure. The partial prosthetic foot can also offer the peak pressure to reduction both amputated foot and unaffected foot and help to toe off during walking.

Patients with lumbar spinal stenosis may exhibit symptoms such as back pain, radiating pain, and neurogenic claudication. Although long-term outcome of treatments manifests similar results for both nonsurgical and surgical treatments, positive effects such as short-term improvement in symptoms and decreased fall risk may be expected with surgery. Surgical treatment is basically decompression, and a combination of treatments can be added depending on the degree of decompression and the accompanying instability. Recently, minimally invasive surgery has been found to result in excellent outcomes in the treatment of lumbar spinal stenosis. Therefore, better treatment effects can be anticipated with an approach aimed at understanding the overall pathophysiology and treatment methods of lumbar spinal stenosis.

Herpes zoster, an acute viral infection produced by the varicella zoster virus, may affect any of the trigeminal branches. This case report presents a patient with symptoms mimicking odontogenic pain. No obvious cause of the symptoms could be found based on clinical and radiographic examinations. After a dermatologist made a diagnosis of herpes zoster involving the third trigeminal branch, the patient was given antiviral therapy. Two months later, the facial lesions and pain had almost disappeared, and residual pigmented scars were present. During the diagnostic process, clinicians should keep in mind the possibility that orofacial pain might be related to herpes zoster.

Six cases of nasal septum perforation were found among welders during periodic physical checkup in 1997. Considering the size, shape and margin, the perforations were assumed to have been occurred several years before of which the diameter were 8~15 mm. To investigate the cause of perforation, we reviewed the past history of preemployment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt, and analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we presupposed that the nasal septum perforations of welders were due to chronic exposure to low level hexavalent chromium and/or nickel, and report these cases with literatures review.

Since coronary arteriovenous fistula(CAVF) was first reported by Krause in 1865, more than 400 cases have been reported. It is relatively rare disease and originates more commonly in the right than in the left coronary artery. We report a case of CAVF between right coronary artery and right ventricular inflow tract with significant left to right shunt in a 34-year old female who was admitted for the cardiomegaly on routine chest X-Ray. It was detected by transthoracic and transesophageal echocardiography, and confirmed by cardiac catheterization and coronary angiography. The opening of the fistula draining into the right ventricle was obliterated with sutures. There was no significant shunt in postoperative cardiac catheterization and coronary angiography.

PURPOSE: Maspin is known as a tumor suppressor gene, but its significance has been questioned in various human cancers. The aim of this study was to investigate the expression pattern of Maspin in human gastric adenocarcinomas and its possible correlation with clinicopathological findings. MATERIALS AND METHODS: The expression of Maspin mRNA was measured by nested RT-PCR using 60 frozen adenocarcinomas of the stomach and 31 noncancerous tissues from the proximal resection margin. Immunohistochemical study for Maspin protein expression was carried out using 62 paraffin-embedded tissues, composed of both cancer and noncancerous tissues. RESULTS: Maspin mRNA expression was detected in 80.0% (48 of 60) of the gastric adenocarcinomas, but in only 22.6% (7 of 31) of the normal gastric mucosa (p<0.001). The positive rate of Maspin protein expression was higher in the adenocarcinomas than the normal tissues (62.9% vs. 27.4%, p<0.05). In addition, the intestinal type of tumors showed significantly higher expression levels compared to the diffuse type of tumors (81.5% vs. 48.6%, p<0.05). CONCLUSION: Our results suggest that Maspin is frequently expressed in human gastric cancers, and its expression might be associated with tumorigenesis of the intestinal type of gastric cancer.

PURPOSE: To demonstrate the impact of correcting sagittal balance (SB) on functional outcomes of surgical treatment for degenerative spinal disease and actual falls via utilization of new minimally invasive lumbar fusion techniques via a lateral approach. MATERIALS AND METHODS: From November 2011 to March 2015, we enrolled 56 patients who underwent minimally invasive lateral lumbar interbody fusion (LLIF) and matched 112 patients receiving decompression/postero-lateral fusion (PLF) surgery for lumbar spinal stenosis. According to SB status using C7-plumb line-distance (C7PL) and surgery type, patients were divided into three groups: SB PLF, sagittal imbalance (SI) PLF, and LLIF groups. We then compared their outcomes. RESULTS: The mean C7PL was 6.2±13.6 mm in the SB PLF group, 72.9±33.8 mm in the SI PLF group, and 74.8±38.2 mm in the LLIF group preoperatively. Postoperatively, C7PL in only the LLIF group improved significantly (p=0.000). Patients in the LLIF group showed greater improvement in fall-related functional test scores than the SI PLF group (p=0.007 for Alternate-Step test, p=0.032 for Sit-to-Stand test). The average number of postoperative falls was 0.4±0.7 in the SB PLF group, 1.1±1.4 in the SI PLF group, and 0.8±1.0 in the LLIF group (p=0.041). Oswestry Disability Index and the Euro-QoL 5 dimension visual analogue scale scores also showed greater improvements in the LLIF group than in the SI PLF group at postoperative 1 year (p=0.003, 0.016). CONCLUSION: Surgical correction of SI in patients with lumbar spinal stenosis using a combination of minimal invasive LLIF and posterior surgery achieved better surgical outcomes and a lower incidence of actual falls than PLF surgery.

Hepatic angiomyolipoma is a rare benign lipomatous tumor of the liver. Radiologic studies usually reveal a fat component, but since this may be minimal, such a component is not always detected. We report a case of atypical hepatic angiomyolipoma which because of the non-visualization of fat at CT and MR imaging, was difficult to differentiate from other hypervascular tumors.
