A review of the literature reveals only one case of neonatal Escherichia coli pericarditis. This is a case report of Escherichia coli pericarditis occurring in a two day old infant. The infant initially presented with lethargy and jaundice but this rapidly progressed into shock. Despite vigorous resuscitative efforts, the infant succumbed and at autopsy 30 cc of purulent fluid were obtained. Cultures of the admission blood and post-mortem pericardial effusion grew Escherichia coli. The clinical diagnosis of pericarditis is often difficult because of vague, nonspecific symptoms and signs. The symptoms are usually those of sepsis plus those of impaired circulation due to mechanical embarrassment by accumulating pericardial effusion. It is difficult to differentiate pericarditis with effusion from myocarditis and pericardial effusion secondary to congestive heart failure. The use of pericardiocentesis as a diagnostic tool and echocardiography are the most helpful techniques presently available for diagnosis. Management consists of vigorous supportive efforts, antibiotics, and drainage of the pericardial effusion. Because of the very high mortality associated with this disorder, a high index of suspicion with a vigorous diagnostic and therapeutic approach to the patient is indicated.

Five cases of coagulopathy caused by consumption of indanedione (diphacinone)-based rodenticides are reported. In each case, acute onset of lethargy and respiratory distress were the predominant initial clinical signs. Thoracic radiography revealed pulmonary edema, pleural effusion, and/or pericardial effusion as consistent findings. Laboratory evaluations confirmed coagulopathies that responded to vitamin K1 therapy.

A 64-year-old man was admitted with complaints of lethargy, malaise, weight loss and transient left-hemiplegia and aphasia. Initial physical and laboratory findings showed splenomegaly and pericardial effusion. During his hospital stay, his mental status deteriorated progressively. The characteristic pathology of malignant reticulosis was noted at autopsy. Microscopic examination of the brain demonstrated accumulations of malignant histiocytic cells confined within small vessels and subsequent multiple hemorrhages and necroses in the gray matter. Malignant reticulosis with antemortem manifestations of pericardial effusion and central nervous system involvement is rare.

In a survey of 15,272 canine necropsies, natural infection with Mycobacterium tuberculosis was found to have been diagnosed in eight dogs (0.05%). Clinical findings were anorexia, loss of body weight, lethargy, vomiting, and leukocytosis; radiography revealed pleural and pericardial effusion, ascites, and hepatomegaly. Granulomatous lesions with acid-fast bacilli were consistently found. Mycobacterium tuberculosis was isolated from lesions in the lungs, liver, or lymph nodes of five dogs. All eight dogs had a history of contact with human patients with tuberculosis.

A 33-yr-old homosexual man with acquired immune deficiency syndrome (AIDS) and Mycobacterium avium intracellulare (MAI) infection presented with fever, sweats, lethargy and dyspnea. A chest radiograph showed cardiomegaly and an echocardiograph revealed a large pericardial effusion. After pericardial aspiration, which confirmed T cell non-Hodgkin's lymphoma, he remained dyspneic. Gallium-67 imaging was performed to determine whether the patient's residual dyspnea was related to pulmonary MAI infection or lymphomatous infiltration of the heart. Planar 67Ga scintigraphy revealed intense tracer uptake in two areas within the mediastinum and surrounding the entire heart shadow but no evidence of pulmonary MAI infection. SPECT 67Ga scintigraphy precisely localized the two mediastinal abnormalities and demonstrated the tracer uptake around the heart to be pericardial rather than myocardial. Gallium-67 scintigraphy suggested that pericardial lymphoma was the likely basis of the patient's dyspnea.

A 76-year-old woman suffered from sudden loss of consciousness while sitting in a chair. She was sent to a local hospital and found to be in shock. After a brief period of external cardiac massage, she was transferred to our hospital. In our emergency department she was lethargic with cool, clammy extremities. Her blood pressure dropped from 113/53 mmHg on arrival to 72/42 mmHg 2 hours later. Echocardiography showed massive pericardial effusion, fair left ventricular contractility and no abnormal segmental motion. The echocardiographic appearance suggested fibrin-like substance in the pericardial space, which was felt to indicate the presence of blood. Enhanced chest computerized tomography showed extravasation of contrast medium from the right ventricular outflow tract. At surgery, a small perforation was found at the infundibular area of the right ventricle, and a total of 500 mL of blood had accumulated in the pericardial space. She was discharged 7 days postoperatively, having made an uneventful recovery. External cardiac massage may cause cardiac disruption, and this should be considered in patients who have secondary hemodynamic instability following successful cardiopulmonary resuscitation.

A 16-year-old male white cockatoo was presented with lethargy and a decreased appetite. Auscultation between the second and third sternal rib revealed a heart murmur, which was confirmed by electrocardiographic and phonocardiographic examination to be systolic, with a shift of the heart axis to -152 degrees. Radiographs showed lack of detail in the cranial part of the abdominal coelom, indicative of ascites and an enlarged cardiac shadow, while ultrasonographic examination revealed pericardial effusion and fluid accumulation in the cavitas peritonealis hepatica. An extra fluid-filled cavity was found at the atrioventricular junction in the right cardiac wall and colour Doppler examination demonstrated a turbulent jetstream of blood into the cavity, originating directly above the aortic valve. Non-selective angiocardiography confirmed the ultrasonographic observations. Findings were indicative of an aneurysm of the a. coronaria dextra (right coronary artery). This was confirmed by necropsy which revealed atherosclerosis to be the underlying cause.

Hydrops fetalis (HF) consists of an abnormal accumulation of fluid in two or more fetal compartments, including ascites, pleural effusion, pericardial effusion, and skin edema. Almost all observed cases of HF are of the nonimmune type, the causes of which remain undetermined in 15% of patients. We report a newborn infant with nonimmune hydrops fetalis (NIHF) and congenital hypothyroidism. The infant's mother was healthy and there were no malformations of the placenta or umbilical cord. The infant did not show any structural abnormalities of his central nervous, cardiovascular, gastrointestinal, or urinary tract systems, and there was no evidence of anemia, infectious disease, or inborn error of metabolism. An immune-based process was unlikely, because the blood group of the mother and infant was A-positive and results of an indirect Coombs test in the mother and a direct Coombs test in the infant were negative. The patient's condition gradually improved with mechanical ventilation, repeated thoracocentesis, and total parenteral nutrition. By day 5 of age the skin edema, pericardial effusion, and ascites disappeared, but accumulation of significant amounts of chylous pleural fluid persisted. Because of lethargy, FT4 and thyroid-stimulating hormone levels were obtained and showed hypothyroidism. Thyroid hormone supplementation was then started, and within 4 days the infant became more vigorous and was weaned from mechanical ventilation. After 7 days, the chylothorax resolved completely as the serum thyroxine level normalized. No reaccumulation of pleural effusion was noticed. The infant started to gain weight and was discharged from the hospital at 35 days of age. A possible pathophysiologic association between congenital hypothyroidism and NIHF is discussed. NIHF may be caused by lymphatic congestion attributable to an impairment of lymphatic flow and a delayed return of lymph to the vascular compartment. There could be a possibility that because of thyroid hormone deficiency in this patient, there was reduced adrenergic stimulation of the lymphatic system. This could result in a sluggish flow of the lymph with engorgement of the lymphatic system, leakage of lymph into the pleura and the interstitial spaces, and the production of chylothorax with NIHF. Animal studies demonstrate a direct relationship between lymph flow rate or lung liquid clearance and adrenergic receptor activity in the lymphatic system. These observations support our hypothesis that deficient adrenergic activity in congenital hypothyroidism might lead to chylothorax with NIHF in the fetus. We speculate that thyroid hormone may play a role in the regulation of adrenergic receptors in the lymphatic system and lungs, thus modulating both the lymphatic flow rate and lung liquid clearance, and facilitating the resolution of chylothorax. Examination of thyroid functions should be included in the investigation of fetuses and neonates with NIHF of an obscure origin.

The unique clinical and pathological findings in nine Asian (Elephas maximus) and two African (Loxodonta africana) elephants from North American Zoos with a highly fatal disease caused by novel endotheliotropic herpesviruses are described. Identification of the viruses by molecular techniques and some epidemiological aspects of the disease were previously reported. Consensus primer polymerase chain reaction (PCR) combined with sequencing yielded molecular evidence that confirmed the presence of two novel but related herpesviruses associated with the disease, one in Asian elephants and the second in African elephants. Disease onset was acute, with lethargy, edema of the head and thoracic limbs, oral ulceration and cyanosis of the tongue followed by death of most animals in 1 to 7 days. Pertinent laboratory findings in two of three clinically evaluated animals included lymphocytopenia and thrombocytopenia. Two affected young Asian elephants recovered after a 3 to 4 wk course of therapy with the anti-herpesvirus drug famciclovir. Necropsy findings in the fatal cases included pericardial effusion and extensive petechial hemorrhages in the heart and throughout the peritoneal cavity, hepatomegaly, cyanosis of the tongue, intestinal hemorrhage, and ulceration. Histologically, there were extensive microhemorrhages and edema throughout the myocardium and mild, subacute myocarditis. Similar hemorrhagic lesions with inflammation were evident in the tongue, liver, and large intestine. Lesions in these target organs were accompanied by amphophilic to basophilic intranuclear viral inclusion bodies in capillary endothelial cells. Transmission electron microscopy of the endothelial inclusion bodies revealed 80 to 92 nm diameter viral capsids consistent with herpesvirus morphology. The short course of the herpesvirus infections, with sudden deaths in all but the two surviving elephants, was ascribed to acute cardiac failure attributed to herpesvirus-induced capillary injury with extensive myocardial hemorrhage and edema.

Ultrasonography was used to diagnose pericardial effusion, atrial dilatation and liver masses in a spur-thighed tortoise which was more than 80 years old and suffering from posthibernation anorexia, lethargy, oedema and pneumonia. The tortoise was treated twice with frusemide and ceftazidime for the pneumonia, resulting each time in a temporary remission for about a month. After a further recurrence, the animal was euthanased and the lesions predicted by ultrasound were confirmed postmortem. It is suggested that ultrasound may be useful for the differentiation of cardiac problems from other causes of posthibernation lethargy in the tortoise.
