Background & Objective: Hiccups is a disabling condition of lateral medullary infarction (LMI). Unlike other symptoms of LMI, the anatomical lesions of hiccups are not well known. Few studies have evaluated the relationship between the lesional location of LMI and hiccups. We performed this study to correlate hiccups and magnetic resonance imaging (MRI)-based lesional location in pure LMI. Methods: Between January 1997 and February 2013, we identified 24 patients with pure LMI who presented with hiccups in addition to typical lateral medullary syndrome. Sixty six pure LMI patients without hiccups were included as a control group. Clinical and radiologic findings were compared between the two groups. MRI-identified lesions were classified rostrocaudally as rostral, middle and caudal, and horizontally as typical, ventral, large, lateral and dorsal. Results: The pure LMI patients with hiccups had significantly more frequent aspiration pneumonia (P = 0.001) and longer hospital stay (P = 0.03). The patients with hiccups significantly more often had dorsal rather than ventral lesion at horizontal levels (P = 0.012). But, there were no rostro-caudal differences at vertical levels (P = 0.162). Conclusions: We suggest that pure LMI associated with hiccups often locates in the dorsal medulla at horizontal correlation. This MRI-based comparative study has advanced the understanding of the neural substrate for hiccups in LMI, and indicates that hiccups become predictable when specific lesional locations in the lateral medulla are considered.

PURPOSE: This is a retrospective study to evaluate the response rate, acute toxicity, and survival rate of a combined chemotherapy and radiation therapy in limited disease small cell lung cancer. MATERIALS AND METHODS: Forty-six patients with limited disease small-cell lung cancer who underwent combined chemotherapy and radiation therapy between October 1994 and April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP regimen (etoposide, ifosfamide, and cis-platin) or a EP regimen (etoposide and cis-platin). Thoracic radiation therapy was planned to deliver 44 Gy using 10MV X-ray, starting concurrently with chemotherapy. Response was evaluated 4 weeks after the completion of the planned chemotherapy and radiation therapy, and the prophylactic cranial irradiation was planned only for the patients with complete responses. Acute toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and disease-free survival were calculated using the Kaplan-Meier Method. RESULTS: The median follow-up period was 16 months (range : 2 to 41 months). Complete response was achieved in 30 (65%) patients, of which 22 patients received prophylactic cranial irradiations. Acute toxicities over grade III were granulocytopenia in 23 (50%), anemia in 17 (37%), thrombocytopenia in nine (20%), alopecia in nine (20%), nausea/vomiting in five (11%), and peripheral neuropathy in one (2%). Chemotherapy was delayed in one patient, and the chemotherapy doses were reduced in 58 (24%) out of the total 246 cycles. No radiation esophagitis over grade III was observed, while interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The local recurrences were observed in 8 patients and local progressions were in 6 patients, and the distant metastases in 17 patients. Among these, four patients had both the local relapse and the distant metastasis. Brain was the most common metastatic site (10 patients), followed by the liver as the next common site (4 patients). The overall and progression-free survival rates were 79% and 55% in 1 year, and 45% and 32% in 2 years, respectively, and the median survival was 23 months. CONCLUSION: Relatively satisfactory local control and survival rates were achieved after the combined chemotherapy and radiation therapy with mild to moderate acute morbidities in limited disease small cell lung cancer.

Shigellosis is an acute inflammatory colitis by infection to one of the members of the genus Shigella. It is known that various CNS symptoms including headache and seizure can develop with shigellosis. Encephalopathy with severe brain edema in shigellosis were rarely reported even in children as well as in adults. We report a rare case of acute encephalopathy with shigellosis showing severe diffuse brain edema which resolved rapidly with administration of steroids in an adult.

Osler-Weber-Rendu disease is characterized by epistaxis, cutaneous telangiectasia, and visceral arteriovenous malformations (AVMs). A 65-year-old male with recurrent epistaxis, old infarction and recent multiple rib fractures caused by a bicycle accident had middle cerebral thromboembolic infarctions when he stopped taking clopidogrel due to massive epistaxis and hemopneumothorax. On examinations, there was no focal cerebral stenosis, but there were telangiectasia, pulmonary and hepatic AVMs. A suspicious Osler-Weber-Rendu disease patient should be evaluated by proper screening and regular follow-up to minimize serious sequelae such as thromboembolic stroke.
