Ankle arthrodesis has been regarded as a good operative treatment for post traumatic and rheumatoid arthritis of ankle, and ankle arthroplasty has been also developed with several types, from 1970, by Lord & Marotte. Ankle arthroplasty is more functional & less cosmetic troublesome than arthrodesis, and with more developed prosthesis design, more good result will come. The authors operated 6 cases of total ankle arthroplasty for posttraumatic and rheumatoid arthritis of ankle, which were also indications of arthrodesis, and introduce the results and operative problems of ankle arthroplasty.

PURPOSE:It is important to evaluate the healing process of avascular necrosis (AVN) involving femoral head after treatment. The purpose of this study was to assess the usefulness of pinhole bone scintigraphy in the AVN of femoral head after surgery. MATERIALS AND METHODS: We analyzed the changing pattern of pinhole bone scintigram in 21 femoral heads of 16 patients (14 lesions/11 male, 7 lesions/5 female, mean age: 39.4 yrs) before and after multiple drilling or vascularized bone grafting for AVN of the femoral head. In all patients, pre-operative scintigrams were obtained at 1 to 3 months before treatment and the first post-operative scintigrams were obtained at 1 to 3 months after treatment. All patients were followed for 2 to 4 years after operation. RESULTS: The findings of the pinhole scintigrams were divided into three patterns: 1) curvilinear, 2) scattered spotty and 3) undetermined. The 10 of 11 lesions with curvilinear pattern had good postoperative clinical and radiological follow-up findings. However, all 6 lesions with scattered spotty pattern showed poor postoperative findings, which necessitated total hip joint replacement. Of the 4 lesions with undetermined pattern, 2 required total hip joint replacement. There was significant difference in postoperative prognosis between the curvilinear and scattered spotty patterns (p<0.05). CONCLUSION: We conclude that the pattern of pinhole bone scintigram obtained within 1 to 3 months after multiple drilling or vascularized bone graft operation is a useful prognostic indicator in the AVN of femoral head.

Ocular disturbances related to cranial nerve lesion or increased intracranial pressure are well known in cryptococcal meningitis, but internuclear ophthaloplegia is very rare and only two cases have been reported to our knowledge. We report the third patient of internuclear ophthalmoplegia in cryptococal meningitis. The internuclear ophthalmoplegia in our case persisted for one year with a demonstrable lesion in brain MRI, in contrast to the other cases in which intranuclear ophthalmoplegia was transient and no responsible lesion was observed.

OBJECTIVE: This study aimed to comprehensively evaluate psychosocial risk factors associated with suicidality in patients with schizophrenia in Korea. METHODS: The study sample consisted of 84 hospitalized patients with schizophrenia. Suicidal thoughts and a clear desire to be dead within 2 weeks were defined as a current suicidal ideation. Socio-demographic and clinical variables, including family history of completed suicides and psychiatric illnesses, were collected, and the Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Beck Depression Inventory (BDI), Simpson-Angus Scale (SAS), Scale to assess Unawareness of Mental Disorder (SUMD), and Alcohol Use Disorders Identification Test (AUDIT) were administered to identify factors associated with a current suicidal ideation. RESULTS: Forty-three subjects (51.2%) reported clear suicidal ideation. Multivariate analysis revealed that later age of illness onset, previous suicide attempt, family history of completed suicide, depression, or substance abuse, fewer than one family visitation to the hospital per month, and score on the CDSS were independently related to current suicidal ideation in these subjects. Age, education level, and scores on the SUMD were not significantly associated with current suicidal ideation in the multivariate analysis, but were associated with suicidal ideation in a univariate analysis on the level of p<0.1. CONCLUSION: The above clinical factors should be evaluated to predict and prevent suicidal risk in patients with schizophrenia. In particular, modifiable factors such as depression should be managed to reduce suicidality of hospitalized patients with schizophrenia.

We treated a 66 year-old-male patient with non-traumatic spontaneous E. coli meningitis, whose cerebrospinal fluid showed turbid, and from which E. coli was cultured, and who had urinary tract infection and fatty liver disease which were thought to be predisposing factors to the meningitis. Gram-negative bacillary meningitis is a very rare condition after the neonatal period, and may be complicated by penetrating cranial injuries, neurosurgical interventions or such debilitating diseases as diabetes, liver cirrhosis, urinary tract infection, malignancy and alcholism, etc. It has a high mortality rate in spite of using various antibiotics.

Repetitive nerve stimulation test(RNS) was performed on 32 patients with myasthenia gravis who showed positive response to the tensilon test. The result of the repetitive stimulation test before and after the tensilon injection was compared with the point of improvement of the CMAP and decremental response. The results were as follows: 1. All patients with myasthenis gravis showed decremental responses to the low rate of stimulation in RNS. 2. The results after tensilon injections showed significant improvements of the CMAP in ocularis oculi(OOC), flexor carpi ulnaris(FCU)(P <0.0005), deltoid and abductor digiti quinti muscles(ADQ)(P < 0.005). 3. There were improvements of decremental responses after tensilon injection. 1) At 2/sec, there were significant improvements in the muscles of ADQ(P <0.005), deltoidl OOC and FCU(P < 0.0005). 2) At 3/sec, there were significant improvements in the muscles of OOC(P <0.005), deltoid, FCU and ADQ(P < 0.0005). 3) At 5/sec, there were also significant improvements in all the muscles of OOC, deltoid, ADQ, FCU(P <0.0005). These results showed that tensilon improves the RNS abnorrnalities in myasthenic patients with positive tensilon test. We think these findings before and after the tensilon injection are helpful to diagnose and differentiate a patient with suspected myasthenia gravis who has a negative tensilon test or insignificant RNS findings.

PURPOSE: Enterovirus infection in children can manifest various disease and enterovirus have many serotypes. This study was aimed to investigate neurologic manifestations according to serotypes of enterovirus in pediatric inpatients in Incheon. METHODS: We collected the stool samples from the admitted pediatric patients in Inha University Hospital from January 2015 to September 2016. Enterovirus detection and serotypes identification were performed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) and semi-nested RT-PCR. RESULTS: A total of 527 samples were collected during study period and 170 patients (32.2%) were diagnosed with enterovirus infections. Genetic sequences of enteroviruses were identified: echovirus 18 (50, 40.5%), enterovirus 71 (12, 9.6%), coxakievirus A10 (10, 8.0%), echovirus 6 (7, 5.6%). Virus in patient with meningitis were identified: echovirus 18 (15, 75%), coxakievirus B5 (2, 10%), enterovirus 71 (2, 10%), and echovirus 6 (1, 5%). Neurologic manifestations of echovirus 18 are headache (15, 30%), vomiting (17, 34%), meningeal irritation sign (10, 20.0%). And enterovirus 71 have headache (3, 25%), vomiting (3, 25%), meningeal irritation sign (2, 16.0%), seizure (1, 8.3%), neurologic sequelae (1, 8.3%). Echovirus 18 and neurologic manifestation have a statistically significant correlation with other serotypes (r=0.701, P < 0.01) CONCLUSION: Echovirus 18 infection was more prominent in neurological symptoms than in other serotypes. The major serotype of meningitis was echovirus 18 but there was no reported neurologic sequelae. Enterovirus infection has different neurological symptoms, depending on the serotypes.
