Benign convulsion with mild gastroenteritis (CwG) is a type of afebrile seizure that occurs in children. CwG is defined as a convulsion in a previously healthy child with no known central nervous system infection or encephalopathy, accompanying mild diarrhea without fever, electrolyte imbalance, or moderate to severe dehydration. Convulsions in CwG are characterized by multiple brief episodes of generalized or focal seizures. Although the etiology and pathophysiology have yet to be fully explained, many pathogenic mechanisms have been proposed including the possibility of direct invasion of the central nervous system by a gastrointestinal virus such as rotavirus or the possibility of indirect influence by the production and effects of certain mediators. The electroencephalogram findings are benign and long-term antiepileptic treatment is typically not required. Long-term prognosis has been favorable with normal psychomotor development. This review provides a general overview of CwG with the goal of allowing physicians practicing in the field of pediatrics to better recognize this unique entity and, ultimately, to minimize unnecessary evaluation and treatment.

To investigate the possible involvement of outward potassium (K+) currents in nitric oxide-induced relaxation in intestinal smooth muscle, we used whole-cell patch clamp technique in freshly dispersed guinea-pig ileum longitudinal smooth muscle cells. When cells were held at -60 mV and depolarized from - 40 mV to + 50 mV in 10 mV increments, sustained outward K+ currents were evoked. The outward K+ currents were markedly increased by the addition of 10 muM sodium nitroprusside (SNP). 10 muM S-nitroso-N-acetylpenicillamine (SNAP) and 1 mM 8-Bromo-cyclic GMP (8-Br-cGMP) also showed a similar effect to that of SNP. 1 mM tetraethylammonium (TEA) significantly reduced depolarization-activated outward K+ currents. SNP-enhanced outward K+ currents were blocked by the application of TEA. High EGTA containing pipette solution (10 mM) reduced the control currents and also inhibited the SNP-enhanced outward K+ currents. 5 mM 4-aminopyridine (4-AP) significantly reduced the control currents but showed no effect on SNP-enhanced outward K+ currents. 0.3 muM apamin and 10 muM glibenclamide showed no effect on SNP-enhanced outward K+ currents. 1 muM 1H-(1,2,4)oxadiazolo (4,3-a)quinoxaline-1-one (ODQ), a specific inhibitor of soluble guanylate cyclase, significantly blocked SNP-enhanced K+ currents. We conclude that NO donors activate the Ca2+-activated K+ channels in guinea-pig ileal smooth muscle via activation of guanylate cyclase.

To determine the incidence, clinical characteristics and coronary angiographic findings of postinfarction angina, clinical course and coronary angiogram were studied in 45 patients with acute myocardial infarction. During a mean follow-up period of 12 weeks, 17 patients(37.8%) developed angina. Of 5 patients with postinfarction angina within 1 week of infarction, 2 patients died during hospitalization, whereas all 12 patients with postinfarction angina which occured more than 1 week after acute myocardial infarction were discharge alive. The frequency of stenosis over 90% and multivessel disease by coronary angiography were 51.7% and 64.7% respectively in patients with postinfarction angina, and 25%, 28.5% respectively in patients without postinfarction angina.

Intramuscular Stimulation (IMS) is a refined technique of traditional oriental acupuncture, and IMS has proved effective for relieving chronic pain of a neuropathic origin. IMS is currently seen to be quite a safe procedure with minimal complications having been reported to date. Various complications have been documented for acupuncture, but few complications or adverse effects have been reported in relation to the relatively new technique of IMS. We report here on a case of cervical spinal epidural hematoma that manifested as a cause of delayed hemiparesis. The safety of this procedure in unpracticed hands seems to be questionable.

Miller-Fisher syndrome is an acute poly-neuropathy typically characterized by the triad of ophthalmoplegia, ataxia, and areflexia. Other poly-neuropathy diseases include Guillain-Barre syndrome and Bickerstaff brainstem encephalitis. However, not all cases of Miller-Fisher syndrome have the typical three symptoms. These diseases have been differentiated by clinical manifestations and anti-GQ1b IgG antibody testing. In Miller-Fisher syndrome, anti-GQ1b IgG antibody is present in over 95% of patients; however, the frequency is not so high in normal subjects or in those with other poly-neuropathy diseases. Infectious illnesses, such as respiratory diseases and gastrointestinal diseases, usually precede Miller-Fisher syndrome. In general, Miller-Fisher syndrome is a self-limiting illness; however, a few cases of Miller-Fisher syndrome progressing to respiratory failure have been reported, particularly in children. In this case, we report abnormal angiographic findings. We report a case of atypical Miller-Fisher syndrome with internal carotid artery stenosis treated with prednisolone.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. PVNS occurs in two types: localized and diffuse. Localized type is characterized by focal involvement of the synovium with either nodular or pedunculated masses, Diffuse type affects virtually the entire synovium. Diffuse type has reported more recurrence rate. We have experienced a patient who has diffuse type PVNS of ankle joint and report an optimal method of surgical treatment.

Epileptic nystagmus is defined as a quick, repetitive jerky movement of the eyeball associated with seizure activity. In cases of epileptic nystagmus associated with ictal discharge from multiple brain areas, localization of the exact epileptogenic zone could be extremely difficult. In a nine-year-old patient with epileptic nystagmus and vertigo associated with bilateral temporal and frontal lobe epilepsy, we could infer the epileptic focus by interpreting the patient's clinical picture, characteristics of nystagmus, and findings of electroencephalography.

The vascular actions of local anesthetics are important in determining the uptake and distribution of these agents from their site of injection as well as influencing their hemodynamic effects once absorbed. Because of the importance of the endothelium in determining of modulating the vascular response of a wide variety of agents, cumulative dose-dependent vasular effects of lidocaine, mepivacaine and bupivacaine on isolated rings of thoracic aorta in normotensive rats(NTR) and spontaneously hypertensive rats(SHR) were studied in the presence and absence of intact endothelium. The results were as follows ; The body weight of NTR and SHR averaged 274.71+/-55.80(N = 38) and 241.43+/-17.73gm(N = 18) and mean arterial pressure was 74.4l+/-3.60 and 129.34+/-2.89mmHg respectively. The mean absolute value of the contraction induced by 5Xl0(-6) M phenylephrine was 3.27+/-0.98(N = 18) and 2.3l+/-50.64gm(N = 18) with intact endothelium and 3.12+/-0.92 and 2.46+/-0.87 gm without intact endothelium in aortic rings of NTR and SHR respectively. In the response to local anesthetics in preparation with resting tension(1.0 gm), lidocaine and mepivacaine in concentration of 10(-3) to 1.25X10(-2) M not produced dose dependent contraction in aortic ring with intact endothelium from NTR. but bupivacaine produced dose-dependent contraction in aortic rings with intact endothelium from NTR. In the aortic rings from NTR and SHR previously contracted with phenylephrine, lidocaine in contraction of 10(-3) to 1.25X10(-2) M caused dose related relaxation in aortic rings with or without endothelium but in concentration of 10(-3) to 510(-3) M, aortic rings with endothelium were more relaxed than those af without endothelium in NTR. In SHR, aortic rings without endothelium in concentration of 5X10(-3) to 1.25X10 M were more significantly relaxed than those of with endothelium. In aortic rings from NTR previously contracted with phenylephrine, mepivacaine caused dose-related relaxation, which was more profound in SHR. In aortic rings with endothelium from NTR previously contracted with phenylephrine, bupivacaine in concentration of 10(-3) to 1.5X10(-3) M caused a relaxation and in concentration of 2.5X10(-3) to 7.5X10(-3) M and 1.25X10(-3) M caused a relaxation again. But in the aortic rings without intact endothelium, bupivacaine caused dose-related relaxation. In the aortic rings without intact endothelium, bupivacaine caused dose-related relaxation in NTR. In the aortic rings from SHR previously contracted with phenylephrine, bupivacaine caused dose-related relaxation, which was more profound than those of NTR. The local anesthetics appear to exert their relaxant effect on endothelium independently and more profoundly in SHR.

OBJECTIVE: This study was performed to prove the significance of the oligohydramnios in the intrauterine growth restriction. METHODS: Eighty two patients were identified to have intrauterine growth restriction with oligohydramnios (Group of IUGR+Oligihydramnios) and fifty six patients were identified to have intrauterine growth restriction without oligohydramnios (Group of IUGR) on ultrasound examination from January 1st, 2005 to December 31st, 2007 at St. Vincent Hospital of Catholic University of Korea. Perinatal outcomes were compared between two groups. RESULTS: Statistically significant differences were not shown between two groups in the maternal characteristics and fetal clinical features except amniotic fluid index and the duration between diagnosis and delivery. The incidence of hyperbilirubinemia and complications in the urogenital system were significantly increased in the group of IUGR+ Oligihydramnios. The other complications were not shown significant difference between two groups. CONCLUSION: Oligohydramnios may not seem to be significant predictor of adverse neonatal outcome of IUGR except the development of hyperbilirubinemia and urogenital complications.

Mucormycosis is an uncommon, frequently fatal, opportunistic fungal infection. Rhinocerebral and pulmonary involvement are the most common forms and usually occur in immunecompromised patients. Gastrointestinal involvement is extremely rare, the stomach being the most frequently involved site among them. When gastric mucormycosis presents as an invasive fungal infection the prognosis is extremely poor. Alternatively when the fungus may colonize the gastric mucosa without invasion of the blood vessels, the prognosis is good. Early diagnosis and tirnely institution of aggressive treatment is essential for the patients with mucormycosis. We report a 72-year-old man of gastric mucormycosis confirmed by histologic examination of endoscopic biopsy specimen. The patient was admitted. to intensive care unit under the diagnosis of adult respiratory distress syndrome and sepsis. He has been suffered from 5 years of end stage renal disease and 4 months of pulmonary tuberculosis and managed by continuous ambulatory peritoneai dialysis and anti-tubereulosis medications. On the 5th hospital day, esophagogastroduodenoscopy was underwent to remove the pieces of thermometer accidentaly broken, which revealed the 1.0 cm ulcerative lesion on the posterior wall of the upper body of stomach. The base of ulcer was coated with whitish-yellow dirty exudates and slightly irregular and the margin was nodular. The mucosae were friable and easily bled with light touch. The histologic examination of biopsy specimen revealed the multiple non-septated fungal hyphae branching right-angle.
