BACKGROUND: The neuropathy disability score (NDS) is a type of clinical grading method for diabetic polyneuropathy. In clinical practice, a nerve conduction study (NCS) is routinely employed as a non-invasive test for the evaluation of polyneuropathy. However, the consensus regarding the degree of abnormalities in NCS as a parameter for the severity of the disease is lacking. The objective of our study is to assess the relation between NDS and NCS parameters and thus verifying the reliability of our new NCS grading method in the representation of objective neurological defects. METHODS: Seventy three patients (man 31, women 42) with diabetes mellitus were included in the study. The NDS was scored in each patient by a single examiner and a NCS was performed on one side of extremities by an experiencedtechnician. Also, the gastrocnemius-soleus H-reflex was performed and analysed for the representation of a deep tendon reflex. The observed values of CMAP and CNAP were transformed into square root and log values. The transformed individual amplitudes and nerve conduction velocities were graded in relation to the mean normal values and standard deviations of our control group study. Then, the sum of the graded score was calculated in each individual and was correlated to the NDS using correlational analysis. RESULTS: There has been a significant linear relationship between NDS and our new NCS scoring system (Pearson's correlation coefficient r=0.703, p<0.01) CONCLUSIONS: The study showed significant correlations between NDS and our new grading system for NCS. Thus, NCS appears to reliably represent theobjective neurologic findings. In asddition, the quantititive grading of NCS would be useful in determining the grade of peripheral polyneuropathy in diabetic patients.

Few patients with traumatic aortic laceration remain undiagnosed and survive long enough to develop a chronic aneurysm. Such aneurysms are frequently asymptomatic: alternatively, they may manifest chest pain, dysphagia, bronchial irritation, or sudden death. A case of aortobronchial fistula secondary to a chronic post-traumatic aneurysm of the aortic isthmus is presented. Hemoptysis was the main sign. The affected segment of the thoracic aorta was repaired with a Hemashield patch and a left upper lobectomy was performed.

Statement of problem. Titanium is the most important material for biomedical and dental implants because of their high corrosion resistance and good biocompatibility. These beneficial properties are due to a protective passive oxide film that spontaneously forms on the surface. Purpose. The purpose of this study was to evaluate the responses of osteoblast-like cells on different surface treatments on Ti discs. Material and Methods. Group 1 represented the machined surface with no treatment. Group 2 surfaces were sandblasted with 50microm Al2O3 under 5 kgf/cm2 of pressure. Groups 3 and 4 were sandblasted under the same conditions. The samples were treated on a titanium oxide surface with reactive sputter depositioning and thermal oxidation at 600degree C (Group 3) and 800degree C (Group 4) for one hour in an oxygen environment. The chemical composition and microtopography were analyzed by XRD, XPS, SEM and optical interferometer. The stability of TiO2 layer was studied by potentiodynamic curve. To evaluate cell response, osteoblast extracted from femoral bone marrow of young adult rat were cultured for cell attachment, proliferation and morphology on each titanium discs. Results and Conclusion. The results were as follows : 1.Surface roughness values were, from the lowest to the highest, machined group, 800degree C thermal oxidation group, 600degree C thermal oxidation group and blasted group. The Ra value of blasted group was significantly higher than that of 800degree C thermal oxidation group (P=0.003), which was not different from that of 600degree C thermal oxidation group (P<0.05). 2. The degree of cell attachment was highest in the 600degree C thermal oxidation group after four and eight hours (P<0.05), but after 24 hours, there was no difference among the groups (P>0.05). 3. The level of cell proliferation showed no difference among the groups after one day, three days, and seven days (P>0.05). 4. The morphology and arrangement of the cells varied with surface roughness of the discs.

Boerhaave's syndrome has the worst prognosis of the esophageal perforation, despite the advancement in the treatment of esophageal perforation due to the development of ICU care and antibiotics. There were controversies in the treatment of esophageal perforation when diagnosed after 24hrs. From 1995 to 2000, we performed a buttressed primary repair and mediastinal drainage in 6 Boerhaave's syndrome patients among 13 esophageal perforation patients. Two patients died(33%). They died because of pneumonia, ARDS and sepsis on 38th, 39th post-operative day respectively. Two patients had leak at the site of repair which was treated completely with conservative treatment. We report on the result of a buttressed primary repair and mediastinal drainage for 6 Boerhavve's syndrome patients.

BACKGROUND AND SIGNIFICANCE: Cytomegalovirus(CMV) is the most common opportunistic viral agent encountered in AIDS and its relation to peripheral neuropathy and rapidly developing lumbosacral polyradiculopathy has been well documentated. CASE: A 30-year-old man with acquired immune deficiency syndrome presented with rapidly progressive paraplegia and voiding difficulty. Electrophysiologic studies revealed a lumbosacral polyradiculopathy with loss of bulbocavernous reflex and CSF examination showed polymorphonuclear pleocytosis with elevated protein level. Also, spinal T1-weighted MRI with gadolinium-DTPA showed enhancement of the pial lining of the conus medullaris, cauda equina, and lumbar nerve roots. Anti CMV titers were elevated in CSF and culture for CMV in both blood and urine was positive. The patient was treated with ganciclovir. CONCLUSION: We report a case of polyradiculopathy related to CMV in a patient with acquired immune deficiency syndrome(AIDS). It seems to be important to differentiate this unique syndrome from other causes of rapidly developing paraplegia syndromes among AIDS patients.

We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.

OBJECTIVES: This study was designed to examine whether melatonin has a neuroprotective effect against hippocampal neuronal damage following transient global ischemia in a gerbil. Polyamine is known to play a role in the pathophysiology of ischemic neuronal damage, we evaluated the influences of melatonin on the polyamine level as well as histology. MATERIAL AND METHODS: Male Mongolian gerbils (60-80 g) were used in this study. Transient global ischemia was induced by occlusion of the bilateral common carotid arteries for 3 min with microclips. Melatonin was administered immediately after occlusion. The animals were decapitated 24 h after the occlusion for polyamine measurement by a high performance liquid chromatography (HPLC) and 4 days after the occlusion for histological evaluation (hematoxylin and eosin staining). A histological examination was performed by a blinded investigator. RESULTS: The hippocampal putrescine level increased compared to sham-operated animals and the increase of putrescine was attenuated by 20 mg/kg melatonin administration. Spermidine and spermine levels didn't show significant changes after ischemia. Hippocampal neuronal damage in the CA1 region was markedly observed in vehicle-treated animals compared to sham-operated animals. Melatonin administration (10 or 20 mg/kg) significantly inhibited hippocampal CA1 neuronal damage after ischemia compared to corresponding vehicle-treated animals (p<0.05 and p<0.01, respectively). CONCLUSION: Melatonin attenuates the putrescine level after transient global ischemia and may have putative neuroprotective effects against global ischemia induced neuronal damage.

Ticlopidine is an inhibitor of platelet aggregation used in the management and prevention of thromboembolic disorders. Hematological toxicity is one of the most important side effects of ticlopidine, including neutropenia, thrombocytopenia and more seriously aplastic anemia. We reported here two cases of very severe aplastic anemia developed after the use of ticlopidine. Both patients suffered from an acute cerebral infarction. Both patients developed pancytopenia 56 days and 51 days after treatment with 500 mg of ticlopidine daily. Both patients were hospitalized and received empiric antibiotic therapy and G-CSF. Twenty-three days and thirty days after the withdrawal of ticlopidine, the hematologic parameters of each patient improved.

Bilateral sudden sensorineural hearing loss (SSNHL) is rare and usually indicates a serious systemic pathology. We describe an unusual case of bilateral SSNHL caused by sepsis. A 28-year-old female complained of acute-onset bilateral hearing impairment; in addition to otological symptoms, she had a systemic condition that met the criteria for sepsis. We performed a physical examination and laboratory tests to diagnose sepsis. Pure tone audiogram and videonystagmography were performed to evaluate the otological symptoms. Intravenous antibiotics and high-dose methylprednisolone were prescribed for treatment, and audiogram was repeated during that period. The fever subsided and the vital signs were stabilized. The electrolyte imbalance and abnormal urine parameters became normal. Hearing gradually recovered to a normal level on day 7 of hospitalization. In conclusion, sepsis should be considered as a cause of SSNHL. When conducting a detailed examination of patients with bilateral SSNHL, the clinician should consider systemic disease.

The adrenal cortical carcinoma is a rare cancer with an estimated incidence of about 1 case per 1,700,000 population. Further development of the tumor thrombi invasion of the inferior vena cava is very rare. The adrenal cortical carcinoma has poor prognosis due to delayed onset of symptoms and signs with regional and metastatic diseases are about 70M at the time of diagnosis. The diagnosis is made by hormonal and imaging studies. Adrenal cortical carcinoma is slightly more frequent in female and hormonally non-functioning tumor is more frequent. Traditionally, surgery and mitotane chemotherapy are known as a valuable therapeutic modality. But recently usefullness of mitotane is questioned due to low response rate and complication such as gastrointestinal trouble and there is not established optimal dosage and duration of treatment. Recently, in metastatic adrenal cortical carcinoma, some literature with combined chemotherapy had tried and reported good response. But, in general, combined chemotherapy has known as ineffective. We experienced and report adrenal cortical carcinoma with inferior vena caval invasion which is diagnosed by computed tomography and magnetic resonance imaging, and we treated surgery and postoperative chemotherapy.
