The number of domestic cases of pandemic H1N1 influenza A was elevated in 2009. The common clinical symptoms associated with H1N1 influenza include respiratory symptoms such as cough, sore throat, rhinorrhea, fever, chills, myalgia, and fatigue. Gastrointestinal symptoms are relatively common. H1N1 influenza A infection brings about neurological symptoms in rare cases. However, there are few reports about H1N1 influenza A infection with neurological manifestations. We recently experienced an H1N1 influenza A patient who presented with disturbed mental status, seizures, and focal changes on brain magnetic resonance imaging, associated with infection.

Orbital varix is a relatively rare disease that causes exophthalmos due to increase of cerebral venous pressure. We experienced a forty-two-year-old male patient, who complained of intermittent exophthalmos and blurred vision. The diagnosis was based on clinical manifestation and various radiologic studies including computed tomography(CT), venography, and magnetic resonance imaging(MRI). MRI is a useful and safe diagnostic study through which we could observe the orbital varix and assess the relationship between the varix and the orbital structure. In this case, the varix is huge and attached to superior rectus muscle. There being many surgical risks, he has been followed up without surgical treatment and educated to modify the life pattern for prevention of increase of carotid venous presure.

Neuroleptic malignant syndrome (NMS), a potentially fatal adverse reaction to neuroleptics, is known to occur more often in the initial stage of antipsychotic treatment. We describe a patient with chronic schizophrenia who, in a few days after the addition of antituberculotic drugs to his antipsychotic regimen, developed probable NMS without pyrexia. We reasoned that rifampin, a strong hepatic enzyme inducer, decreased the plasma chlorpromazine concentration of the patient, with the result of cholinergic hyperactivity and finally, the symptoms of NMS. Therefore, physicians should be aware of drug interactions and the likelihood of NMS, and consider antipsychotic dose adjustment when prescribing drugs that may influence pharmacokinetic properties of antipsychotics in a patient with schizophrenia receiving long-term antipsychotic treatment.

BACKGROUNDS: Gamma band oscillatory activity is considered to be related to congnitive functions and illustrates that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. An event-related gamma oscillation is the time - locked responses of specific frequency, and can be identified by computing the amplitude frequency characteristics of the averaged event-related potentials(ERPs) after stimulation. OBJECTIVES: We purposed to present experimental paradigm to investigate @-band oscillation activities from the recording of ERPs by using auditory oddball paradigm and investigate the difference of @-band activity between schizophrenia and normal controls. METHODS: The ERPs resulting from auditory stimuli with oddball paradigm in a group of schizophrenics(n=11) and also a group of age-, sex- and handedness matched normal controls, were recorded by 128 channel EEG. The @-band oscillatory activities were calculated by using time-frequency wavelet decomposition of the signal between 20 and 80Hz. The @-band oscillatory activities of both groups were compared by t-test. RESULTS: The @-band oscillatory of the leads Fz,Gz and Pz of both groups were represented well in the time - frequency maps. Significant increases of the @-band activity in normal controls compared with schizophrenics were observed around 160 msec. 350msec. and 800 msec after stimulation. CONCLUSIONS: Our results suggested that the increment in @-band oscillatory activity during cognitive operations and decreased @-band activity in schizophrenics may be associated with the cognitive dysfunctions and the pathophyiology of the schizophrenia.

PURPOSE: Carpal tunnel decompression with limited one-incision technique has been reported that it is possible to achieve a sufficient decompression without significant complications. We evaluated the clinical effectiveness of this method. MATERIALS AND METHODS: Forty-two cases of twenty-eight patients of carpal tunnel syndrome were retrospectively evaluated, which were treated with limited one-incision technique less than 2 cm in length, from January 1997 to September 1999. RESULTS: According to Cseuz's criteria, 36 cases (85.7%) were excellent or good. CONCLUSION: Carpal tunnel decompression with limited one-incision technique can provide sufficient decompression with small skin incision. It is not necessary of special eqipment. It has less copmplications and no difference of clinical results comparing with classic open method or endoscopic method. Therefore, this method can be a good method in the surgical treatment of carpal tunnel syndrome. But this method can't be performed in the patient with abnormal anatomical structure or tumorous conditions in carpal tunnel and complication rates are not zero. Therefore operator should pay attention to the selection of patients and the technique.

Renal angiomyolipomas are benign mixed mesenchymal tumors, which are composed of atypical blood vessel, smooth muscle and fat cells. A 34-year-old woman presented with a palpable right abdominal mass, accompanied with discomfort. A CT scan showed a large right perinephric mass, with heterogeneous density, surrounding the kidney, with enlargement of the regional lymph nodes. The presumptive diagnosis was one of a malignant tumor of the retroperitoneum, with lymph node metastasis or an angiomyolipoma, involving both the kidney and lymph nodes. A right radical nephrectomy, including the tumor, was performed. The final diagnosis was an angiomyolipoma arising from the kidney, with the dissected lymph nodes having the same pathology. There was no evidence of a tumor recurrence during the six month follow-up period. This was an unusual case of a multicentric angiomyolipoma.

PURPOSE: Torus palatinus is a bony prominence at the middle of the hard palate. The size varies from barely discernible to very large, from flat to lobular. This oral exostosis is not a disease or a sign of disease, but if large, may be a problem. So, we present the clinical and histopathologic features and applied therapy and provide a comprehensive review of the rare case of the symptomatic exostoses. METHODS: A 37-year-old woman had slowly growing exophytic nodular mass of the bone that arises the midline suture of the hard palate. The patient was concerned about discomfort associated with movement of her tongue and about frequent irritation of the palatal mucosa during mastification of the hard food. The patient had a large, unilobulated torus palatinus. It extended from the area adjacent to the canine to a point beyond the junction with the soft palate. The mass was oblong in shape, measuring about 3cm long, 2cm wide, and 0.8cm in height. RESULTS: Before surgical intervention a CT was obtained for the sake of estimating the thickness of the bone between the exostoses and the maxillary antrum and floor of the nose. The surgical procedure was performed with the patient under general anesthesia. Removal of the exostosis was performed after midline mucoperiosteal incision with osteotome and diamond burr. Histologic finding revealed decalcified dense bony tissue, the presence of lacunae, and normal osteocytes. CONCLUSION: Surgical removal is recommended when one or more of the following condition exist: interference with the construction of prosthesis, interference with oral function, irritation or pathology of the overlying tissue, inability of the patient to maintain proper oral hygiene, and fear of malignancy or other psychologic trauma. We report a rare case of the torus arising in hard palate with symptoms.
