A case of aconitine poisoning saved with cardiopulmonary bypass

"Torikabuto" is a kind of plant which contains deadly poison. Its ingredient is aconitine alkaloids. We report a case of aconitine poisoning with fatal arrhythmia and acute pulmonary edema who was saved with cardio pulmonary bypass. A 41-year-old male ate to mistake "Torikabuto" for wild plant. He developed symptoms of dysarthria and admitted to our hospital. He developed ventricular tachycardia and fibrillation soon after his admission. Then he developed cardiogenic shock. He was resuscitated and supported with a percutaneous cardio pulmonary bypass. Ventricular tachycardia disappeared 24 hours after admittion. About 1 week later, cardio pulmonary bypass was terminated and about 3 months later, he discharged from our hospital.     

A case of embolization to a large polycystic kidney with infection

75 year old female who was hospitalized for abdominal pain and fever up on 12th May 1998. She had been followed as a polycystic kidney patient since few years. The swelling of the right kidney and her general condition became gradually worse. On 18th May, the embolization to the right kidney using pure alcohol and gelatin sponge was performed. Within a month, CT scan showed the reduced volume of the right kidney and her blood examination data as well as her general condition became gradually well. And on 17th June, she left our hospital without any complication.     

Suicidal attempts in three postoperative patients with renal cancer after alpha interferon withdrawal

We report 3 cases of suicide attempts in postoperative patients with renal cancer after alpha interferon withdrawal. In the first patient, depression occurred during interferon therapy, and remained after interferon withdrawal. A suicide attempt occurred 7 months after interferon withdrawal. In the second and third patients, depression did not occur during interferon therapy, but suicide attempts occurred 40 days and 7 months after interferon withdrawal, respectively. Depression does not always disappear after interferon is discontinued. Psychiatric supervision should be continued even more frequently after interferon withdrawal. The increased risk of psychiatric side effects due to interferon, as well as their severity, suggest that interferon should be administered with caution.     

Patent ductus venosus with a hypoplastic intrahepatic portal system presenting intrapulmonary shunt: a case treated with banding of the ductus venosus

A case of patent ductus venosus (PDV) presenting intrapulmonary shunting is described. Although retrograde venography of ductus venosus showed few intrahepatic branches, banding of PDV resulted in increased intrahepatic portal branches and disappearance of symptoms 10 months after the operation. Banding of the ductus venosus may be effective in PDV even with hypoplastic intrahepatic portal system.     

Total parenteral nutrition-associated intrahepatic cholestasis in infants: 25 years' experience

BACKGROUND/PURPOSE: There are few long-term chronological reviews examining the incidence of total parenteral nutrition (TPN)-associated intrahepatic cholestasis (TPNAC) in infants. The authors therefore reviewed TPNAC in their 25-year series, and also looked at the current problems associated with TPN in infants. METHODS: Two hundred seventy-three surgical neonates who received TPN for more than 2 weeks were divided into 3 groups chronologically: group A (1971 through 1982, n = 77), group B (1983 through 1987, n = 72), and group C (1992 through 1996, n = 124). TPNAC was defined as serum direct bilirubin (DB) level greater than 2.0 mg/dL during the neonatal period. RESULTS: The incidence of TPNAC in groups A, B and C was 57%, 31%, and 25% (P< .01), respectively, and the mortality rate from TPN-associated complications was 13%, 3%, and 3% (P< .05), respectively. Over the last 5 years, severe TPNAC developed in 20 patients (16%). Four of 20 died of TPN-associated sepsis with hepatic failure; 2 had hypoganglionosis with intractable stagnant enteritis and subsequent sepsis, and 2 had fatal respiratory or cardiac disease. CONCLUSIONS: The incidence of TPNAC in surgical neonates and TPN-associated mortality rates have decreased significantly. The mortality rate, however, still remains at 3%. Two of 4 fatal cases had hypoganglionosis, which were totally dependent on TPN. In patients who require long-term TPN, TPN still has unsolved problems, and small bowel transplantation may be indicated.     

Constipation Is a Frequent Problem Associated with Vascular Complications in Patients with Type 2 Diabetes: A Cross-sectional Study

Objective Diabetes is recognized as an underlying disease of constipation. However, the prevalence of constipation varies according to the diagnostic criteria applied. We investigated the prevalence of constipation based on the new guideline for constipation in Japanese patients with type 2 diabetes and examined the relationship with the clinical background, including diabetic vascular complications. Methods Questionnaire surveys including items concerning the diagnosis and treatment status of constipation were administered to 410 patients with type 2 diabetes. Results Although 29% of the patients considered that they had experienced constipation (self-judged), only 14% had consulted a physician about constipation. The prevalence of chronic constipation based on the guideline was 26%. After including laxative users, constipation was finally found in 36%. Despite the use of laxatives (n=81), 51% of the patients were still diagnosed with chronic constipation. Patients with constipation (chronic constipation or laxative use) were significantly older and had a longer duration of diabetes than those without constipation. The body mass index (BMI) of patients with constipation (24.9±3.8 kg/m²) was significantly lower than that of those without constipation (26.3±4.6 kg/m²). Diabetic neuropathy (49% vs. 32%) and coronary heart disease (CHD) (27% vs. 13%) were significantly more frequent in the patients with constipation than in those without constipation. A multivariate logistic regression analysis revealed that gender, BMI, diabetic neuropathy, insulin use, and CHD were significantly associated with constipation. Conclusion An accurate diagnosis of constipation is desirable in patients with type 2 diabetes because constipation is independently associated with CHD.     

Role of tumor necrosis factor-alpha and interleukin-1beta on lung dysfunction following hemorrhagic shock in rats.

BACKGROUND: Hemorrhagic shock occasionally causes a fatal outcome following an outbreak of lung dysfunction, but the precise mechanism has not been clearly elucidated. Several studies have indicated that hemorrhagic shock causes a delayed vascular inflammatory decompensation and leads to inflammation-related organ dysfunction. Tumor necrosis factor (TNF)-alpha and interleukin (IL)-1beta are known as major proinflammatory cytokines that play an important role in excessive autolytic inflammation, finally inducing organ dysfunctions. In this study, the role of TNF-alpha and IL-1beta on lung dysfunction following hemorrhagic shock was examined by using FR167653, a potent inhibitor of TNF-alpha and IL-1beta production that acts by suppressing p38 mitogen-activated protein kinase (MAPK). MATERIAL/METHODS: Hemorrhagic shock was induced in anesthetized male rats by bleeding via a common carotid catheter for 20 minutes to 25% of total body blood volume without fluid resuscitation. Mean blood pressure, heart rate and arterial blood gas components were recorded up to 5 hours after the bleeding. The levels of TNF-alpha, IL-1beta and lactic dehydrogenase (LDH)-3 isozyme were measured in the serum of pulmonary venous blood. The lung tissue was excised for the assay of mRNA and for histopathological study. RESULTS: The expressions of mRNA for TNF-alpha and IL-1beta in the lung tissue and the concentrations of both cytokines in pulmonary serum increased after a hemorrhage. Inflammation-related injuries and function deterioration were observed in the lung following hemorrhagic shock. These hemorrhagic changes were inhibited by pretreatment with FR167653. CONCLUSIONS: TNF-alpha and IL-1beta play a key role in the development of inflammation-related lung dysfunction following hemorrhagic shock. Our model should be useful to explain the pathogenesis of lung dysfunction following hemorrhagic shock.     

Prediction of maximal cardiac output in preoperative patients with coronary artery disease

Of 100 patients (89 men, 11 women) studied preoperatively to determine their aerobic and hemodynamic profiles at rest and during upright treadmill exercise. The mean maximal cardiac output (CO), measured using the direct Fick principle, was 57 ± 14% of average normal values. The reduction in maximal heart rate (63 ± 13% of normal) was a greater factor in the reduction in CO than stroke volume (88 ± 16% of normal). Maximal oxygen consumption (V?O₂max) was 48 ± 15% of normal and the greater reduction in V?O₂₂max compared with CO was due to lower peripheral extraction in the coronary patients. Variables that correlated with maximal CO in a univariate analysis included angina severity (r = ?0.45), V?O₂₂max (r = 0.67), maximal heart rate (r = ?0.31), left ventricular dysfunction (r = ?0.45), maximal systolic blood pressure (r = ?0.31) and number of vessels with ≥ 50% diameter reduction (r = ?0.3). Resting ejection fraction did not correlate with maximal CO. In a multivariate analysis, 4 variables correlated significantly (r = 0.77) with maximal CO: in order, V?O₂₂max, number of vessels with ≥ 50% stenosis, magnitude of ST depression and sex.
