We report a case of serotonin syndrome that occurred in a patient with chronic heart failure associated with a panic disorder. The 39-year-old Japanese man had been treated with paroxetine at 20 mg/d for 1 1/2 years. He presented with rhabdomyolysis, renal failure, fulminant liver failure, cardiac conduction disturbance, and disseminated intravascular coagulation, as well as conventional symptoms of serotonin syndrome including alterations in cognition (disorientation, confusion) and behavior (restlessness), autonomic nervous system dysfunction (fever, shivering), and abnormal neuromuscular activity (ataxia, hyperreflexia, myoclonus). All medications prescribed before hospital admission were discontinued. After 24 hours of continuous venovenous hemofiltration, diuresis resumed and renal and liver function improved rapidly. Disorientation, restlessness, hyperreflexia, and myoclonus abated slowly over the next 72 hours. The patient's anxiety subsided more slowly, and he recovered completely 1 week later. The plasma concentration of paroxetine was elevated far above the upper limit of the therapeutic range. The patient had cytochrome P-450 (CYP) 2D6*1/*5, a heterozygosity of an inactivated allele of CYP2D6, which metabolizes paroxetine. The patient was determined to be an intermediate metabolizer who was potentially vulnerable to paroxetine, a major inhibitor of CYP2D6. Heart failure is often accompanied by psychiatric disorders. A wide range of drugs commonly prescribed for these conditions, including beta-blockers, antiarrhythmics, and antidepressants, are metabolized by CYP2D6. Genetic screening for CYP2D6 in patients with these conditions may prevent life-threatening drug intoxication.

Endotoxic shock, one of the most prominent causes of mortality in intensive care units, is characterized by pulmonary hypertension, systemic hypotension, heart failure, widespread endothelial activation/injury, and clotting culminating in disseminated intravascular coagulation and multi-organ system failure. In the last few years, studies in rodents have shown that administration of low concentrations of carbon monoxide (CO) exerts potent therapeutic effects in a variety of diseases/disorders. In this study, we have administered CO (one our pretreatment at 250 ppm) in a clinically relevant, well-characterized model of LPS-induced acute lung injury in pigs. Pretreatment only with inhaled CO significantly ameliorated several of the acute pathological changes induced by endotoxic shock. In terms of lung physiology, CO pretreatment corrected the LPS-induced changes in resistance and compliance and improved the derangement in pulmonary gas exchange. In terms of coagulation and inflammation, CO reduced the development of disseminated intravascular coagulation and completely suppressed serum levels of the proinflammatory IL-1beta in response to LPS, while augmenting the anti-inflammatory cytokine IL-10. Moreover, the effects of CO blunted the deterioration of kidney and liver function, suggesting a beneficial effect in terms of end organ damage associated with endotoxic shock. Lastly, CO pretreatment prevents LPS-induced ICAM expression on lung endothelium and inhibits leukocyte marginalization on lung parenchyma.

Diffuse neonatal hemangiomatosis (DNH) is a rare, frequently fatal disorder characterized by multiple cutaneous and visceral hemangiomas. Complications include high-output cardiac failure, hemorrhage, hepatic failure, and consumption coagulopathy. We present two cases of neonates with DNH. We prescribed cyclophosphamide after failure of corticosteroids. Cyclophosphamide induced a fast regression of the lesions with no side effects in both infants. We were able to stop treatment after 3-4 courses of cyclophosphamide in both infants because of the excellent response. Cyclophosphamide seems to be a safe and effective treatment in patients suffering from life-threatening DNH unresponsive to corticosteroids.

Under observation there were 29 casualties with severe combined trauma complicated by acute heart failure (AGF) caused by a direct injury of the heart, without severely disturbed consciousness and valuable blood loss. In 65% of the patients the trauma was severe, in 35%--extremely severe. Higher ST wave was registered in ECG of 40% of the patients in standard leads, in 30% there was no wave R in chest leads. Disturbed rhythm was noted 2-2.5 times more often than in other kinds of injuries. Ventricular extrasystoles, paroxysmal ciliary arrhythmia, atrioventricular and ideoventricular rhythm were determined since the first day after trauma. The results of the investigation have shown that the primary injury of the myocardium was followed by a decreased heart work. Circulatory insufficiency of blood circulation was developed. The impaired systemic hemodynamics led to inadequate delivery of oxygen to the tissues and of oxygen consumption, to the development of tissue hypoxia and respiratory disorders closely connected with it. The circulation disturbances caused also a suppression of detoxication mechanisms of organism, the development of disseminated intravascular coagulation and endotoxicosis.

A thorough review of the literature and of personal files has allowed the gathering of 81 patients with rare congenital bleeding disorders and thrombotic phenomena. Sixteen of these patients had congenital afibrinogenemia, eight involved factor V deficiency, 20 factor VII defects, 33 factor XI deficiencies and only one, a factor XIII defect. Altogether 42 patients showed arterial thrombosis (myocardial infarction [MI] in 28 cases; ischemic stroke in 4; arterial occlusion in 8; 2 patients with disseminated intravascular coagulation (DIC)). Ages varied between 13 and 74. Twenty-two patients were males and 16 females. In four cases, sex was not reported. There were three fatalities: two after a MI and one because of heart failure. With regard to venous thrombosis: 9 patients had pulmonary embolism, 15 patients had deep vein thrombosis, 9 patients had both pulmonary embolism and deep vein thrombosis; 1 patient had superficial vein thrombosis, whereas, 5 cases had an unusual site venous thrombosis (two portal systems, two cerebral sinuses, one inferior vena cava) for a total of 39 cases. Age varied between 3 and 86. In this case, 20 patients were males and 17 were females. In two cases, sex was not reported. There were three fatalities: two because of pulmonary embolism and one because of inferior vena cava thrombosis. The fact that thrombosis has never been described in patients with factor II or factor X seems to underscore the central antithrombotic role that these two factors have in the coagulation system.

Peripartum cardiomyopathy (PC) and preeclampsia with HELLP syndrome are serious complications of pregnancy, but the coincidence of both in one pregnancy is extremely rare. Here, we report a case of 32-year-old primipara who in 35th Hbd presented for the first time in her life symptoms of severe heart failure (HF) in NYHA class III/IV. In 37th Hbd the diagnosis of PC was established based on clinical status and echocardiographic examination, which demonstrated a dilatation of heart chambers and impaired left ventricular systolic function with decreased ejection fraction (EF) 17%. In 37th Hbd she developed symptoms of preeclampsia complicated with HELLP syndrome (hemolysis, elevated liver enzymes, low platelets) and further a DIC syndrome as well. Because the patient was in critical condition and the foetus' life was threatened the pregnancy was terminated with urgent cesarean section. Then the patient developed shock, respiratory insufficiency and increasing renal failure. Successful treatment, included administration of pressor amines, respirator, hemodialyses, multiple fresh frozen plasma and blood transfusions. The symptoms of HELLP syndrome resolved by 9th day of treatment. Although optimal treatment of HF was administered with significant clinical improvement, the normalization of left ventricle systolic function was not observed. At 2 and 13 months follow-up, EF remained low and was 34 and 36% respectively. This allows to diagnose persistent PC. Based on the case, the issues of etiopathogenesis, treatment, prognosis and the risk of recurrence of PC and HELLP syndromes in a possible pregnancy are discussed.

We experienced 2 patients of valvular heart disease in Parkinson's patients taking cabergoline. Patient 1 was a 79-year-old woman who began taking 4 mg cabergoline daily after being diagnosed with Parkinson's disease (PD) in June 2003. She presented with dyspnea in November 2005. The patient had cardiomegaly, pulmonary congestion, and pleural effusion, and an echocardiogram showed valvular heart disease in the form of aortic regurgitation (AR) (grade I), tricuspid regurgitation (TR) (grade I), and mitral regurgitation (MR) (grade III). Cabergoline was thought to have caused these phenomena, so it was replaced with pramipexole, and after administration of diuretics and angiotensin-converting enzyme inhibitors (ACEIs) the patient's symptoms gradually disappeared. MR, AR and TR also disappeared 3 months later. Patient 2 was a 74-year-old woman who presented with sluggish movement in April 2001 and subsequently developed Parkinson's. While being administered 700 mg levodopa (Menesit) and 4 mg cabergoline, the patient presented with shortness of breath in April 2005. An echocardiogram showed valvular heart disease in the form of MR (grade I) and TR (grade I). Heart function improved with the administration of diuretics. However, heart function again worsened in November 2005, and the patient presented with edema of the lungs and lower limbs. An echocardiogram in January 2006 showed worsening MR (grade III) and TR (grade II), and the patient also had pulmonary hypertension. ACEIs were administered along with diuretics and cabergoline was replaced with pramipexole, but the patient also developed malignant syndrome and disseminated intravascular coagulation (DIC) and later died. Patient 2 is the first case in Japan of death due to heart failure caused by the side effects of cabergoline. Caution is usually needed when treating a Parkinson's patient for valvular heart disease due to a dopamine agonist, and periodic checks for heart murmurs and echocardiography are crucial. When signs of heart failure develop during treatment with an ergot preparation of dopamine agonist, it is essential to immediately either stop the administration of the ergot preparation or change to a non-ergot preparation of dopamine agonist.

We report the case of a primary gastrointestinal stromal tumor (GIST) found in the greater omentum of an extremely elderly woman. A 99-year-old woman with a history of heart failure and renal failure presented with dyspnea and disturbance of consciousness. A tumor located between the stomach and spleen had been detected by abdominal computed tomography three years previously. After admission, she received oxygen supplementation and diuretics. However she died of heart failure and disseminated intravascular coagulation on the 31st day of hospitalization. Autopsy was performed on the same day. A large mass measuring 12.5 x 7.0 x 7.5 cm was revealed, originating from the greater omentum. Histopathologically, it was composed of spindle cells with the nuclei showing a focal palisading pattern, however there were no mitoses. Immunohistochemically, the tumor was positive for c-kit. The tumor was diagnosed as a primary GIST of the greater omentum.

We report a patient who underwent mitral valve replacement despite acute-stage cerebral hemorrhage related to a complication of infective endocarditis (IE) and rupture of intracerebral mycotic aneurysm, achieving survival. The patient was a 24-year-old female. She consulted our hospital because of a fever and was diagnosed with IE and a cerebral hemorrhage. A blood culture test on admission revealed methicillin-sensitive Staphylococcus aureus. Transthoracic echocardiography revealed giant vegetation in the left atrium. Besides the management of an acute-stage cerebral hemorrhage, medical therapy for IE was performed. However, a severe infection was refractory, and mitral-regurgitation-related heart failure deteriorated. Despite acute-stage cerebral hemorrhage, mitral valve replacement was performed 10 days after admission because advanced disseminated intravascular coagulation syndrome made conservative management difficult. After surgery, neither exacerbation of cerebral symptoms nor recurrent IE was noted, and the patient was discharged.
