The present study was designed to identify the sequential electrophysiological findings ant to determine the prognostic values of electrophysiological and clinical pararneters in patients with Guillain-Barre syndrome (GBS). Severely affected 42 subjects (Grade D,E). Who fulfilled the diagnostic criteria of GBS were selected. Twentynine patients were followed up at least 6 months (range 6-24 months) from the onset of neurologic syrnptorns. We analyzed 83 electrodiagnostic studies from 42 subjects. The sequential electrophysiological abnorrnalities were most marked at 3-4 weeks after the onset. At that time the most significant change was a decrease of CMAP amplitude. By stepwise discriminant analysis of several electrophysiological parameters, the three variables, of CMAP amplitude, distal conduction velocity; and F-wave latency were deterrnined to be significant pararneters. The accuracy of predicting the prognosis at 6 months was 82. 8%, when the classification functions were applied. Nlerefore the findings of early electrophysiological studies would be irnportant in understanding the serial pathophysiological changes and assessing the clinical outcorne of Guillain-Barre syndrorne.

PURPOSE: The detection of epileptogenic lesion plays an important role in the management of patients with partial epilepsy. Although the development of MRI improved the examination of cerebral hemispheres greatly, many patients with neocortical temporal lobe epilepsy (TLE) or extratemporal lobe epilepsy (extra-TLE) still show no lesion in conventional two-dimensional (2D) images. To increase the yield of MRI in those patients, we performed three-dimensional (3D) surface-projection rendering (SPR) of the cerebral hemispheres. METHODS: Conventional 2D MRI (T1, T2, FLAIR, thin slice SPGR) and 3D SPR were performed in 24 patients with neocortical TLE and extra-TLE, and 20 normal subjects. Sulcogyral patterns were evaluated blindly to clinical information. The locations of the epileptogenic zone, ictal onset zone (IOZ) and irritative zone (IRZ) were determined by intracranial EEG monitoring and epilepsy surgery. RESULTS: The 2D MRI identified epileptogenic lesions in five of the 10 neocortical TLE (50%) and five of the 14 extra-TLE (35.7%). 3D SPR revealed abnormal sulcogyral patterns in 9 of the 10 neocortical TLE (90%) and 9 of the 14 extra-TLE (64.3%). Cortical deformation zones with sulcogyral anomalies included the whole area of IOZ in 10 (55.5%) and IRZ in 6 (33.3%), overlapped with IOZ in 7 (38.9%) and IRZ in 11 (61.1%), were connected to IOZ in 1 (5.6%) and IRZ in 1 (5.6%). CONCLUSION: 3D SPR of volumetric MRI data can detect epileptogenic structural lesions of neocortical epilepsy that are not visible in the conventional 2D images.

PURPOSE: To investigate the various ictal perfusion patterns and find the relationships between clinical factors and different perfusion patterns. MATERIALS AND METHODS: lnterictal and ictal SPECT and SPECT subtraction were performed in 61 patients with partial epilepsy. Bath positive images showing ictal hypoperfusion and negative images revealing ictal hypoperfusion were obtained by SPECT subtraction. The ictal perfusion patterns of subtracted SPECT were classified into focal hypoperfusion, hypoperfusion-plus, combined hypoperfusion-hypoperfusion, and focal hypoperfusion only. RESULTS: The concordance rates with epileptic focus were 91.8% in combined analysis of ictal hypoperfusion and hypoperfusion images of subtracted SPECT, 85.2% in hypoperfusion images only of subtracted SPECT, and 68.9% in conventional ictal SPECT analysis. Ictal hypoperfusion occurred less frequently in temporal lobe epilepsy (TLE) than extratemporal lobe epilepsy. Mesial temporal hypoperfusion alone was seen only in mesial TLE while lateral temporal hypoperfusion alone was observed only in neocortical TLE. Hippocampal sclerosis had much lower incidence of ictal hypoperfusion than any other pathology. Some patients showed ictal hypoperfusion at epileptic focus with ictal hypoperfusion in the neighboring brain regions where ictal discharges propagated. CONCLUSION: Hypoperfusion as well as hypoperfusion in ictal SPECT should be considered for localizing epileptic focus. Although the mechanisrn of ictal hypopertusion could be an intra-ictal early exhaustion of seizure focus or a steal phenomenon by the propagation of ictal discharges to adjacent brain areas, further study is needed to elucidate it.

A diagnosis of gout is often straightforward because gout has well known clinical presentations, laboratory analyses, and radiologic features. On the other hand, gout can mimic other diseases by showing a range of atypical clinical manifestations. This paper reports a 35-year-old male with no prior history of gout who developed tophaceous gout at his previously repaired Achilles tendon 11 years after surgery. He was initially misdiagnosed with cellulitis because of his atypical clinical features. This case is presented with a review of the relevant literature.

PURPOSE: The purpose of this study was to assess the satety and effectiveness of lacrimal trephination and balloon dilatation in treatment of obstruction of the lacrimal canaliculus. METHODS: Lacrimal trephination and subsequent balloon dilation was performed in 7 eyes of 7 consecutive patients with epiphora due to lacrimal canalicular obstruction and common canalicular obstruction. RESULTS: The average age of patients was 50.3 years old and the average follow-up period was 17.7 months. Anatomical success was 7 of 7 eyes (100%) and functional success , resolution of epiphora was 5 of 7 eyes (71%) CONCLUSIONS: Lacrimal trephination and subsequent ballooning canaliculoplasty in treatment of obstruction of the lacrimal canaliculus seems to be safe and valuable as an primary procedure before Jones tube bypass surgery.

Objectives:
. The association between pet sensitization and pet ownership remains unclear. Therefore, we aimed to elucidate the association between pet sensitization and pet ownership by age.
Methods:
. We retrospectively reviewed 2,883 patients who visited our allergy clinic for nasal symptoms from January 2003 to December 2014, of whom 1,957 patients with data on skin-prick tests and questionnaire responses were included and divided into adults (age >19 years) and children (age ≤19 years). The association between pet sensitization and pet ownership was evaluated in both groups.
Results:
. Among children, dog and cat sensitization showed no associations with dog and cat ownership, respectively. However, among adults, dog sensitization was significantly associated with dog ownership (odds ratio [OR], 3.283; P<0.001), and cat sensitization with cat ownership (OR, 13.732; P<0.001). After adjustment for age, sex, familial history of allergy, sinusitis, diabetes mellitus, other pet ownership, and non-pet sensitization, significant associations remained between dog sensitization and dog ownership (adjusted OR [aOR], 3.881; P<0.001), and between cat sensitization and cat ownership (aOR, 10.804; P<0.001) among adults. Dog ownership did not show any association with allergic rhinitis, asthma, or atopic dermatitis, whereas atopic dermatitis had a significant association with cat ownership in adults (aOR, 4.840; P<0.001).
Conclusion
. Pet ownership in adulthood increased the risk of pet sensitization. However, pet ownership was not associated with the prevalence of atopic disorders, regardless of age, except for atopic dermatitis and cat ownership in adults.
