The anthelminthic effect of phenylene-diisothiocyanate-(1,4)(=Jonit) was studied on the eighty three cases infected with Ancylostoma duodenale. For the evalution, the number of eggs per gram of feces on all these cases was calculated before treatment. The follow-up for the egg reduction was carried out over a period of four weeks. The sixty-seven cases were treated in dosage schedule of 3 x 100 mg every 12 hours. The cure rates - the rate of negative conversion of eggs - was 74.6 percent and the total egg reduction rate of 94.2% was obtained. The ten out of 14 cases treated in the dosage schedule of 2 x 100 mg every 12 hours showed 100% egg reduction and the cure rate was 71.4%. In this group. the total egg reduction rate of 78.6% was noted. In the dosage schedule of 2 x 50 mg every 12 hours the remainder, two out of total 83 cases showed 100% egg reduction. Side effects were observed as being mild, 51 cases (56.6%) were free of side reactions and the most frequently noted side effects were vertigo and diarrhea. From the above results, it is concluded that Jonit is an effective antheminthic against Ancylostoma duodenale and its effectiveness is quite equivalent to that of a known recommended anti-hookworm products.

Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year- old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/ multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.

Hyperhomocysteinemia is an independent risk factor for atherosclerotic complications in adult patients with chronic renal failure. Data on hyperhomocysteinemia in children with chronic renal failure are not sufficient. In the present study we investigated plasma homocysteine concentration status in children with chronic renal failure, factors correlating plasma homocysteine concentration, and the effect of folate dose increase. We measured fasting plasma homocysteine, folate, vitamin B12, creatinine concentration in 32 children on dialysis and 21 non-renal patients as controls. Then, 21 children of 32 on dialysis were prescribed 2.5mg folic acid daily, instead of 0.8mg daily. Mean fasting plasma homocysteine concentration was 13.8 micromol/L in end-stage renal disease patients and 7.5micromol/L in controls. Serum folate and vitamin B12 concentrations are higher in ESRD patients. Patients on peritoneal dialysis showed higher serum folate concentrations than patients on hemodialysis. Homocysteine levels were significantly correlated with age and creatinine, and negatively correlated with folate and vitamin B12 levels in patients. After 4 weeks of folic acid dose increase, homocysteine levels of patients on hemodialysis were decreased, which contrast with patients on peritoneal dialysis. Children with end-stage renal disease have elevated plasma homocysteine concentrations with 0.8mg folic acid daily, and folic acid dose increase to 2.5mg daily lowers homocysteine level in patients on hemodialysis. It is suggested that folic acid dose be increased for children on hemodialysis to decrease homocysteine level, although a beneficial effect has to be proven.

BACKGROUND: Although stress-induced cardiomyopathy (SCMP) is reported to be more common in women, little is known about gender differences in patients with SCMP. The aim of the study was to describe clinical features of patients with SCMP according to gender. METHODS: One hundred and three patients diagnosed with definite SCMP at a single tertiary institute from January 1997 to August 2014 were enrolled. SCMP was more common in women than in men. RESULTS: Age at presentation was not significantly different between the two groups (p = 0.758). Preceding physical stress, especially acute medical illness, was more common in male patients (p = 0.014), whereas emotional stress was more common in female patients (p = 0.016). Severity of medical illness classified by the Acute Physiology and Chronic Health Evaluation (APACHE) II score at the time of SCMP diagnosis was not significantly different between men and women (p = 0.752). Clinical characteristics, including symptoms, laboratory and electrocardiographic findings, were similar. However, pump failure was more severe in men (p = 0.024). Clinical outcomes were not statistically different (p = 0.220). Preceding physical stress and lower left ventricular systolic function after 2 months were independent risk factors for all-cause mortality for both genders. Women with an APACHE II score ≥ 15 and men with reduced left ventricular ejection fraction after 2 months had a greater risk of poor prognosis. CONCLUSION: SCMP was more common in female patients. Female patients more commonly experienced preceding emotional stress, whereas physical stress was more common in male patients. Systolic dysfunction was more severe in men. Long-term clinical outcomes appeared to be similar between men and women.

Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the stent was overstretched and unrolled into the aorta and the rest of the stent remained implanted in the coronary artery. The stent was captured with a gooseneck snare but could not be retrieved because it was connected to a stent remnant implanted in the coronary artery. The stent strut was cut with rotablation, and the stent was successfully removed through the femoral sheath.

A 77-year-old man visited our hospital complaining of aggravated exertional chest pain. He was diagnosed with syndrome X 7 years ago and underwent medical treatment in a regional hospital. Coronary angiography and echocardiography did not show any significant abnormalities. On the seventh in-hospital day, cardiogenic shock developed and echocardiography showed a dilated left ventricular (LV) cavity and severe LV systolic dysfunction. We thus inserted an intra-aortic balloon pump for hemodynamic support and were forced to maintain it because of weaning failure several times. Finally, heart transplantation was the decided necessary procedure. After successful heart transplantation, the biopsy specimen revealed a wild-type transthyretin deposition indicating senile systemic amyloidosis in the intramuscular coronary vessels and interstitium. Cardiac biopsy at the 4-year follow-up showed no recurrence of amyloid deposition.

Epithelioid hemangioendothelioma (EHE) is a rare tumor of vascular origin. While it can be found in any tissue, it is most often found in lung and liver and usually has an intermediate behavior. EHEs originating from pleural tissue have been less frequently described than those from other sites. Furthermore, to date, all of the cited pleural EHEs were described as highly aggressive. In the present report, we describe a rare case of pleural EHE extending to lung and bone in a 31-year-old woman. The histological diagnosis was confirmed by both conventional examination and immunohistochemistry. Her disease stabilized during the 4th course of adriamycin (45mg/m2, day 1-3), dacarbazine (300mg/m2, day 1-3) and ifosfamide (2,500mg/m2, day 1-3) with mesna, and she survived for 10 months after the diagnosis.

We aimed to investigate that complete revascularization (CR) would be associated with a decreased mortality in patients with multivessel disease (MVD) and reduced left ventricular ejection fraction (LVEF). We enrolled a total of 263 patients with MVD and LVEF <50% who had undergone percutaneous coronary intervention with drug-eluting stent between March 2003 and December 2010. We compared major adverse cardiac and cerebrovascular accident (MACCE) including all-cause death, myocardial infarction, any revascularization, and cerebrovascular accident between CR and incomplete revascularization (IR). CR was achieved in 150 patients. During median follow-up of 40 months, MACCE occurred in 52 (34.7%) patients in the CR group versus 51 (45.1%) patients in the IR group (P=0.06). After a Cox regression model with inverse-probability-of-treatment-weighting using propensity score, the incidence of MACCE of the CR group were lower than those of the IR group (34.7% vs. 45.1%; adjusted hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.44-0.95, P=0.03). The rate of all-cause death was significantly lower in patients with CR than in those with IR (adjusted HR, 0.48; 95% CI, 0.29-0.80, P<0.01). In conclusion, the achievement of CR with drug-eluting stent reduces long-term MACCE in patients with MVD and reduced LVEF.
