PURPOSE: The diabetic charcot neuroarthropathy of ankle is an infrequent site (around 5%), but is definitely the location that, because of the instability and progressive deformity it involves, cause ulceration in a high percentage of patients, and this can then become a reason for amputation. However, the treatment of this disastrous disease is still challenging. We analyzed the clinical and radiological results of ankle arthrodesis by our fixation method in Charcot neuroarthropathy. MATERIALS AND METHODS: Seven cases that were diagnosed as charcot neuroarthropathy of ankle arthrodesis were followed for more than 16 months postoperatively. Mean age was 57 years, and the mean follow-up period was 27 months. Anterior approach was used in arthrodesis, and internal fixation by 3 or more cannulated screws and hybrid type external fixation were used. Auto iliac bone for grafting was combined in all cases. External fixator was kept for 3 months without weight-bearing. Then, boots brace was applied for more 3 months allowing partial weight-bearing. Four cases had minor complications such as pin site infection. Preoperative and postoperative AOFAS score, time to fusion and postoperative complications were checked. RESULTS: Postoperative fusion was completed in all cases, and the mean time to fusion was 3.4 months. No postoperative complication was checked. At the last follow-up, the mean AOFAS score had increased from 54 points to 72 points. Patient's satisfaction was over 80%. CONCLUSION: Satisfactory results were obtained after ankle arthrodesis using internal and hybrid type external fixation combined with auto iliac bone graft in charcot neuroarthropathy with minor complications.

Primary lymphoma of uterine cervix is rare disease, which usually occurs in postmenopausal periods. The usual symptoms are vaginal bleeding, postcoital bleeding. The most common pathologic feature is a diffuse cell type, B-cell line. Pap smear is not helpful in diagnosis because it is stromal origin. Biopsy confirms the diagnosis. Treatment consists of radiation therapy and/or chemotherapy. The prognosis of the disease is dependent upon Ann arbor stage and International index score rather than FIGO stage. We experienced one case of primary lymphoma of cervix and report it with a brief review of literature.

Asbestos exposure may cause asbestosis, pleural plaques and benign pleural disease, and may give a predisposition to malignant mesothelioma in occupationally exposed workers. This case report describes a 50-year-old man, dying from histologically confirmed, diffuse, malignant mesothelioma after asbestos exposure. As a young man, he had been exposed at the workplace to crocidolite for 2 years, but he had no other known history of occupational or environmental asbestos exposure. The patient presented with chest pain and general weakness. Computed tomography showed bilateral irregular pleural thickening along both lower lateral chest walls and a low attenuating mass in the anterior portion of the left lobe. Pathological examinations revealed that it was an epithelial type with tubulopapillary structures and it tested immunohistochemically positive for antibodies against cytokeratin, calretinin and vimentin. The patient was started on chemotherapy but he died to the disease at ten months after the first onset of the symptoms. Mesothelioma is a rare neoplasm in the general population. Nevertheless, the importance of close medical surveillance of the high-risk population is emphasized, because of increased asbestos exposure.

Dimethylformamide (DMF), a widely used industrial solvent, has been reported to induce subtle to clinically overt hepatotoxicity. Liver injury due to occupational exposure through inhalation and skin contact has been sporadically reported. We report a 23-year-old male who developed intermittent abdominal pain, anorexia, nausea, vomiting, chest discomfort, and general weakness for 4 days after working in a plastic-coated-glove factory. An acute hepatitis episode occurred after working in an enclosed workplace for 3 days. Other causes of hepatitis such as viral, drug induced or alcoholic hepatitis, could be excluded or were considered to be unlikely. Based on occupational history, serological examination and serial liver function examinations, the case was compatible with DMF-induced acute toxic hepatitis. Hepatotoxicity due to occupational exposure to solvents (e.g., DMF) should be considered in any patient with unexplained hepatitis. The fast improvement of the clinical symptoms and the progressive normalization of the liver function tests once the DMF exposure has been stopped, supports the diagnosis.

Purpose:
Thioacetamide (TAA) produces reactive oxygen species (ROS) in the liver, and the generated ROS induces liver injury through inflammatory reactions. The current study was undertaken to investigate the hepatoprotective effect of Artemisiae Capillaris Herba water extract (AC), imparted via its antioxidant activity, in an animal model of TAA-induced liver injury.
Methods:
Animal experiments were conducted in 5 groups: normal, control (TAA 200 mg/kg), SM (TAA 200 mg/kg + silymarin 100 mg/kg), ACL (TAA 200 mg/kg + AC 100 mg/kg), ACH (TAA 200 mg/kg + AC 200mg/kg). TAA (intraperitoneal) and treatment compounds (per oral) were administered for 3 days. Serum levels of ammonia concentration and myeloperoxidase (MPO) activity were subsequently measured. Liver tissues were subjected to western blot analysis for measuring the oxidative stress (NADPH oxidase), anti-oxidative activity (Nrf2, heme oxygenase-1 [HO-1], superoxide dismutase [SOD], catalase, and GPx-1/2), tissue inhibitors of metalloproteinase (TIMP)-1, and matrix metalloproteinases (MMPs) protein expressions.
Results:
Serum ammonia levels and MPO activity were significantly increased in the TAAinduced control group, whereas groups administered AC treatment showed markedly reduced levels. Western blot analysis revealed significantly increased NOX2 and p22phox expressions, (oxidative stress-related factors) in the TAA-induced control group. These levels were determined to be significantly decreased after AC exposure. Moreover, antioxidantrelated factors including Nrf2, HO-1, SOD, catalase, and GPx-1/2 were significantly decreased in the control group and increased in the AC treated groups. In addition, MMP expressions were significantly suppressed in the AC treatment group due to increased levels of TIMP-1.
Conclusion
Taken together, these data indicate that exposure to AC reduces the oxidative stress by inhibiting the expression of NADPH oxidase (NOX2 and p22phox ) through the Nrf2 signaling pathway. We therefore propose the potential of AC for the prevention and treatment of TAA-induced liver injury.

Purpose:
Reflux esophagitis is a disease caused by the reflux of stomach contents and stomach acid etc. into the esophagus due to defect in the lower esophageal sphincter and is currently increasing worldwide. This study was conducted to evaluate the effect of a mixture of Citrus Reticulata and Scutellariae Radix (CS) extract on acute reflux esophagitis in rats.
Methods:
Rats were divided into five groups for examination: normal group (Normal, n = 8), water-treated acute reflux esophagitis rats (Control, n = 8), tocopherol 30 mg/kg body weight-treated acute reflux esophagitis rats (Toco, n = 8), CS 100 mg/kg body weight-treated acute reflux esophagitis rats (CS100, n = 8), CS 200 mg/kg body weight-treated acute reflux esophagitis rats (CS200, n = 8). The experimental groups were administrated of each treatment compounds and after 90 min, acute reflux esophagitis was induced through surgery. Rats were sacrificed 5 h after surgery. We measured the level of reactive oxygen species (ROS) in serum and analyzed the expression of nicotinamide adenine dinucleotide phosphate, inflammatory, and tight junction-related proteins by western blot in the esophageal tissues.
Results:
CS administration significantly protected the esophageal mucosal damage due to reflux esophagitis, and the level of ROS in the serum was significantly reduced with CS administration as compared to Control. In addition, CS administration significantly suppressed mitogen-activated protein kinase (MAPK or MAP kinase) and nuclear factorkappa B (NF-κB) pathways and increased protein expressions of tight junction protein.
Conclusion
These results suggest that the CS not only regulates the expression of inflammatory proteins by inhibiting oxidative stress, but also reduces damage to the esophageal mucosa by inhibiting the expression of tight junction proteins.
