The patient was a 56-year-old male. He had a history of alcoholism since 1975 and diabetes mellitus since 1978. He was treated with insulin therapy. But the control of diabetes mellitus was very poor and he had six hypoglycemic comas attacks. He had diabetic triopathy but no symptoms of gait disturbance, dementia and incontinence. Brain computerized tomography and magneting resonance imaging revealed severe communicating hydrocephalus with mild brain atrophy.111In-DPTA cisternography revealed retension of isotope in the ventricle after 48 hours. The pressure of cerebrospinal fluid was normal.
This case report is interesting as it suggests the relationship between normal pressure hydrocephalus and hypoglycemia.

An 78-year-old woman visited our hospital with the chief complaints of abdominal pain, nausea, vomiting and diarrhea. She was operated on for gastric ulcer when she was 56 years old and complained of abdominal discomfort after operation. One day she wished to take Confrey (Symphytum officinale), but she took digitalis leaves (Digitalis purpurea) by mistake. On admission she was drowsy and the systolic blood pressure was 60 mmHg on palpation. Electrocardiograms showed bradycardia, irregular AV-nodal rhythm and ST depressions and T wave inversions with the shortening of the QT interval. Serum levels were potassium, 6.4 mEq/1 ; BUN, 34.4 mg/di ; creatinine, 1.5 mg/di ; digoxin, 2.0 ng/ml (therapeutic level, up to 2.0 ng/ml); and digitoxin, 111ng/ml (therapeutic level, up to 25 ng/ml). Hemodynamic data showed HR, 49 beats/min ; CO, 2.81/min; CI, 2.31/min/m2; SV, 57 ml/beat and SI, 47 ml/beat/m2 on administration of dopamine 7μg/kg/min. So VVI pacing was started at 70 bpm and CO increased to 3.6 1/min after pacing. But unfortunately she died of ventricular fibrillation. The digitalis leaves resemble the Confrey leaves and it is easy to mix up these two plants. Although this is a rare case, digitalis intoxication can be life-threatening. So we should prepared ourselves for the treatment of patients poisoned with digitalis and other poisonous herbs.

This report concerns a 62-year-old woman with Wegener's granulomatosis. She complained cough, macroscopic hematuria and oligulia. She had a consolidation without a cavity in the left upper lung field, massive proteinuria (2.5 g/day) and massive hematuria. The serum creatinine level was 2.5 mg/dl. The C-ANCA was positive. Renal biopsy revealed crescentic glomerulonephritis. She wa treated with prednisone and trimethoprim-sulfamethoxazole. The lung shadow, proteinuria and hematuria disappeared in one month. The C-ANCA titer also decreased. The use of trimethoprimsulfamethoxazole which may eliminate an infection as a cause to promote Wegener's granulomatosis should be actively included in the conventional treatment.

We report a case of reactive hypoglycemic coma in a 77-year-old man. Seven months after partial gastrectomy for early gastric cancer, he presented with syncopal attacks and seizure. His plasma glucose and insulin levels at coma were 18 mg/dl and 27μU/ml. Insulinoma was neglected with computerized tomography, magnetic resonance imaging and angiography. Because dietary control was insufficient, oral diazoxide therapy was done. But diazoxide did not protectthe overresponse of the insulin and reactive hypoglycemia in 75 g GTT. Octreotide (100 micrograms IM) inhibited insulin release and prevented hypoglycemia. Acarbose delayed the response of insulin butdid not inhibited insulin release. However, acarbose also prevented reactive hypoglycemia. We concluded that acarbose is an effective therapy for reactive hypoglycemic coma.

Bovine abortion, diarrhea, and respiratory disease complexes, caused by infectious agents, result in high and significant economic losses for the cattle industry. These pathogens are likely transmitted by various vectors and reservoirs including insects, birds, and rodents. However, experimental data supporting this possibility are scarce. We collected 117 samples and screened them for 44 bovine abortive, diarrheal, and respiratory disease complex pathogens by using Dembo polymerase chain reaction (PCR), which is based on TaqMan real-time PCR. Fifty-seven samples were positive for at least one pathogen, including bovine viral diarrhea virus, bovine enterovirus, Salmonella enterica ser. Dublin, Salmonella enterica ser. Typhimurium, and Neospora caninum; some samples were positive for multiple pathogens. Bovine viral diarrhea virus and bovine enterovirus were the most frequently detected pathogens, especially in flies, suggesting an important role of flies in the transmission of these viruses. Additionally, we detected the N. caninum genome from a cockroach sample for the first time. Our data suggest that insects (particularly flies), birds, and rodents are potential vectors and reservoirs of abortion, diarrhea, and respiratory infectious agents, and that they may transmit more than one pathogen at the same time.

Hypertrophic cardiomyopathy with apical aneurysm is known to have high risk of a sudden death due to ventricular arrhythmias or thromboembolisms. We report a surgical case of surgical case of this disease. A 67-year-old man was found to have abnormality in an electrocardiogram during his checkup, and subsequent careful examinations revealed his disease. He had no symptoms and the pressure gradient at the obstruction was about 30 mmHg, but there was thrombus in the apical aneurysm. After anticoagulant therapy, the thrombus dissolved. We scheduled an operation on him because he was judged to have high risk of a sudden death. In the operation, excision of the apical aneurysm, and hypertrophic midventricular myocardium were performed, concomitant with cryoablation to the border between the aneurysm and normal myocardium. Although complete atrioventricular block occurred postoperatively and he needed permanent pacemaker implantation, he was discharged from the hospital 21 days postoperatively without any other complications. He is doing well at two years and six months, postoperatively.

A 51-year-old woman presented with a high fever and weakness and was diagnosed with mitral valve infective endocarditis. Medical treatment was unsuccessful, and the patient developed disseminated intravascular coagulation syndrome, multiple cerebral infarctions, and massive cerebral hemorrhage. She was transferred to our hospital for surgical treatment. On admission, she had motor aphasia and right-sided hemiplegia. Echocardiography showed mild mitral regurgitation with a huge mobile vegetation measuring greater than 20 mm on the anterior leaflets. Head CT showed a huge cerebral hemorrhage in the left frontal lobe. Chest radiography revealed severe pulmonary congestion, and laboratory data showed disseminated intravascular coagulation syndrome. Despite medical treatment, the pulmonary congestion worsened. There were concerns that a fatal cerebral infarction would develop, and so urgent open-heart surgery was performed. On the day after the cerebral hemorrhage had occurred, hematoma removal and decompressive craniotomy were performed to reduce the risks associated with cardiopulmonary bypass. Four days after the craniotomy, mitral valve plasty was performed following the complete excision of the infected tissue. Heparin was administered at our normal dosage as an anticoagulant during cardiopulmonary bypass. Postoperative head CT showed no aggravation of the preoperative cerebral lesion. The patient still had symptomatic epilepsy and difficulty performing exact movements with her right hand, but she was able to walk unaided after 1 year of rehabilitation. Generally, early surgery for infective endocarditis is not recommended if the patient has concomitant cerebral hemorrhage ; our strategy may be the safest option for patients in such a serious condition.

Anomalous aortic origin of a coronary artery is a rare congenital anomaly that can cause myocardial ischemia and ventricular arrhythmia. This disease initially manifests as cardiac arrest in half of patients. The indications and surgical strategy remain unclear, especially in patients who are asymptomatic and have poor ischemic findings. We report a surgical strategy to treat anomalous aortic origin of the right coronary artery. A 47-year-old man with a chief complaint of chest tightness was diagnosed with anomalous aortic origin of the right coronary artery, which branches from the left sinus of Valsalva and runs an inter-arterial course. Although no objective myocardial ischemia was identified with blood tests, electrocardiography, or cardiac catheterization, we suspected that the cause of the thoracic symptoms was sharp branching of the right coronary artery, which was compressed between the ascending aorta and the pulmonary artery. To reduce the risk of sudden death in the future, we performed reimplantation of the right coronary artery. Good imaging results were obtained, and the patient is currently undergoing outpatient follow up and has not experienced recurrence of chest symptoms. We conclude that our surgical strategy to treat anomalous aortic origin of a coronary artery may be useful in the clinic.

The frozen elephant trunk technique (FET) for the treatment of acute aortic dissection is associated with more favorable remodeling in the descending aorta compared to those patients without FET, but it may also be associated with postoperative spinal cord injury (SCI) and actually,some postoperative SCI cases after FET are reported. Several risk factors for SCI are known and one of them is due to the occlusion of intercostal arteries from false lumen. A 71-year-old woman underwent total arch replacement with FET, but after surgery, she noticed decreased movement in both lower extremities and was suspected of postoperative paraplegia. She went through cerebrospinal fluid drainage but didn't get better at all. According to the preoperative contrast computed tomography images, seven out of ten intercostal arteries were originating from the false lumen and six of them were occluded after surgery. When most of intercostal arteries are originating from the false lumen and there is no entry inside the descending and abdominal aorta, the intercostal arteries may be occluded due to thrombosis of the false lumen and it may cause spinal cord ischemia after surgery.
