PURPOSE: The early diagnosis of Kawasaki disease (KD) is difficult sometimes, especially in atypical or incomplete cases presenting 4 or less principal clinical features without coronary arterial lesions (coronary arterial ectasia or aneurysm). The authors investigated the incidence of echocardiographic abnormalities in patients with KD to discover whether abnormal echocardiographic findings might be helpful in the early diagnosis of KD. METHODS: Echocardiography was done in the acute stage of 103 patients with KD (Kawasaki group) and 40 patients with other acute febrile illnesses (control group). Abnormal echocardiographic findings were classified into 4 categories and defined as follows; 1) significant pericardial effusion, 2) significant valvular dysfunctions, 3) left ventricular systolic dysfunction, 4) coronary arterial ectasia or aneurysm. RESULTS: In the Kawasaki group, significant pericardial effusion was present in 24 patients (23.3 percent), significant valvular dysfunctions in 30 patients (29.1 percent), left ventricular systolic dysfunction in 10 patients (9.7 percent), and coronary arterial lesions in 27 patients (26.2 percent). In the control group, significant pericardial effusion was present in only one patient (2.5 percent). The number of patients with any one of echocardiographic abnormalities was 57 (55.3 percent) in Kawasaki group and one (2.5 percent) in control group. The sensitivity of echocardiography in the diagnosis of KD was 55.3 percent, the specificity 97.5 percent, the positive predictive value 98.3 percent, and the negative predictive value 45.9 percent. CONCLUSION: If abnormal echocardiographic findings, even if other than coronary arterial lesions, are confirmed in patients in whom KD is suspected, it seems desirable to inifiate specific treatment for KD.

Bartha strain of pseudorabies virus[PRV-Ba] was utilized as a tracer to identify the neuronal axis of rat tongue muscles ; intrinsic muscles and extrinsic muscles, styloglossus, genioglossus, and hyoglossus muscle. After injection of 10 microliter of PRV-Ba into tongue muscles and 48-96 hours survivals, rats were perfused with 4% paraformaldehyde lysine periodate and brains were removed. PRV-Ba were localized in neural circuits by immunohistochemistry employing rabbit anti PRV-Ba as a primary antibody and ABC method. Injection of PRV-Ba into the tongue muscles resulted in uptake and retrograde transport of PRV-Ba in the rat brain. The result showed a circuit specific connection of many nerve cell groups along the time sequence : PRV-Ba immunoreactive cells appeared in hypoglossal nucleus and motor trigeminal nucleus ipsilaterally as seen with conventional tracers. Raphe nucleus, prepositus hypoglossal nucleus, spinal trigeminal nucleus, Al, A5 and facial nucleus of rhombencephalon showed immunoreactivity bilaterally. There were positive neurons in parabrachial nucleus, locus ceruleus, mesencephalic trigeminal nucleus, periaqueductal gray and A7 of mesencephalon and paraventricular nucleus, suprachiasmatic nucleus, organum vasculosum of lamina terminalis of diencephalon. Also positive reactions were showed in amygdala, insular cortex, frontal cortex and subfornical organ in telencephalon. Early immunoreactivity was appeared in hypoglossal nucleus and motor trigeminal nucleus, and there were positive neurons in the nuclei of the medulla oblongate, midbrain, pons, hypothalamus, cerebellum and medial preoptic area at middle stage. Subsequently the viral antigens were found in forebrain cell groups, paraventricular nuclei, suprachiasmatic nucleus, lateral hypothalamic area and primary motor cortex in frontal lobe bilaterally at 80-90hrs postinjection. These data demonstrate that the PRV-Ba can across synapses in the central nervous system with projection specific pattern, and this virus defines many elements of the neural network governing tongue. Therefore PRV-Ba are proved as a excellent neurotracer in the tract-tracing researches.

Optic neuritis (ON) is an acute or subacute inflammatory or demyelination process affecting the optic nerve. ON can be classified ophthalmologically as retrobulbar neuritis, papillitis, neuroretinitis. Retrobulbar neuritis, in which the optic disc appearance is normal, is the most common type of ON in adults. Multiple sclerosis is the most common cause of ON, but in many cases no apparent etiology is found. Paranasal sinusitis as a cause of ON is rare. Management of retrobulbar neuritis which is combined with paranasal sinusitis is controversial. Recently, we experienced a case of retrobulbar neuritis which was combined with paranasal sinusitis without orbital complication. It was treated by endoscopic sinus surgery and endoscopic optic nerve decompression in addition to intravenous antibiotics and corticosteroids. Visual acuity was improved nearly to a normal state after the treatment. The most possible pathophysiologic mechanism of retrobulbar neuritis may be the direct spread of infection of the sphenoid sinus to the optic nerve.

The 46, XX male or sex-reversal syndrome is a rare entity, which may be reported first by de la Chapelle and associates in 1964, an additional 135 cases have been recognized, yet only 20 percent of these patients have been diagnosed during childhood. The 46, XX male may be associated with hypogonadism and infertility in adult, and occasionally, sexual ambiguity in the neonate. At least 10% of patients have had hypospadia or ambiguous external genitalia. The 46, XX male was diagnosed with cytogenic study, H-Y antigen, hormonal study testicular biopsy, radiologic study. Here, we report a case of 19 month-old child XX-male with hypospadia and chordee.

Deep vein thrombosis (DVT) is a common disease. However, May-Thurner syndrome, which is the cause of DVT, is an uncommon processes in which there is an impaired venous return due to compression of the left iliac vein by the overlying right common artery. This condition results in a left iliofemoral deep thrombosis and severe leg edema. It is, therefore, called iliac compression syndrome. Catheter-directed thrombolytic therapy of acute extensive iliofemoral DVT and balloon angioplasty with venous stenting are recommended. Two cases with history of left leg swelling are diagnosed as May-Thurner syndrome, which was demonstrated by venography. We successfully treated the patients with thrombolysis, balloon angioplasty, and stent insertion at the site of common iliac vein compression. Therefore, we report the cases with overall review of the literature.

PURPOSE: To evaluate the side effects, pattern of failure, and survival rate according to the sequence of postoperative adjuvant radiotherapy and chemotherapy, patients with stages II and lll rectal cancer who had undergone curative resection were randomized to early radiotherapy group (arm I) or 'late radiotherapy group (arm II)', then we intend to determine the most effective sequence of the radiotherapy and chemotherapy. MATERIALS AND METHODS: From January 1996 to March 1999, 3 13 patients with curatively resected stages II and III rectal cancer have been randomized to early' or late radiation therapy group and recei ved combined chemotherapy (5-FU 375 mg/m/day, leucovorin 20 mg/m, IV bolus daily D1-5, 8 cycles) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Arm I received radiation therapy from day 1 with first cycle of chemotherapy and arm II received radiation therapy from day 57 with third cycle of chemotherapy after completion of first two cycles. Preliminary analysis was performed with 228 patients registered up to Jun 1998. Two out of the 228 patients were excluded because of double primary cancer. Median follow-up period was 23 months. RESULTS: Local recurrence occurred in 11 patients (9.7%) for arm I and 9 patients (8%) for arm II. There was no significant difference between both groups (p=0.64). However, distant metastasis was found in 22 patients (19.5%) for arm I and 35 patients (31.0%) for arm II and which showed statistically significant difference between the two groups (p=0.046). And neither 3-year disease-free survival (70.2% vs 59.2%, p=0.2) nor overall survival (89.4% vs 88.0%, p=0.47) showed significant differences. The incidence of leukopenia during radiation therapy and chemotherapy was 78.3% and 79.9% respectively but leukopenia more than RTOG grade 3 was only 2.1% and 6.0% respectively. The incidence of diarrhea more than 10 times per day was significantly higher in the patients for arm I than for arm II (71.2% vs 4 1.6%, p=0.02) but this complication was controlled with supportive cares. CONCLUSION: Regardless of the sequence of postoperative adjuvant radiation therapy and chemotherapy a fter curative resection for rectal cancer, local recurrence rate was low with combined chemoradiotherapy. But distant metastasis rate was lower in early radiation therapy group than in late radiation therapy group and the reason is unclear. Most patients completed these treatments without severe complication, so these were thought to be safe treatments but the treatment compliance should be improved.
