A 12 years boy presented with the history of pallor for one month. Two days before hospitalisation he developed fever, cough, shortness of breath. He had past history of such episode. On examination, his heart rate was found to be 120/minute, respiratory rate 40/minute and moderate anaemia was detected. Scattered creptus was audible over mid and lower lung fields and a soft systolic murmur was auscultated at apex. On investigations, Hb was found as 4.6 g/dl and HbF was less than 2%. Plasma Hb was 5 g/dl. Straight x-ray chest showed bilateral patchy opacities over mid and lower zones. His sputum was found to be blood stained and prompted the possibility of blood loss occurring in the lungs, which was confirmed by demonstrating haemosiderin laden macrophages on three consecutive sputum specimens. Echocardiography revealed a systolic displacement of mitral valve leaflets into the left atrium with co-optation superior to the plane of mitral annulus. Doppler study showed a minimal late systolic regurgitation. It was decided to treat the case as idiopathic pulmonary haemosiderosis. Oxygen inhalation, hypertonic saline nebulisation, i.v. hydrocortisone, packed cell transfusion followed by oral prednisolone improved the patient's condition. After 3 months of discontinuing prednisolone, he remained asymptomatic. Here one case of pulmonary haemosiderosis characterised by abnormal accumulation of haemosiderin in the lungs following repeated alveolar haemorrhages with the presence of mitral valve prolapse is reported.

One hundred and five wild-caught emerald tree boas (Corallus caninus) were added to a collection of 15 others. in Central Florida, during a 4-mo period. Eighty-one boas (67%) developed repetitive regurgitation during the 23-mo period after the initial introduction, and 61 (75%) of these died. Regurgitation occurred 3-4 days after feeding. Prevalence of regurgitation in this population of snakes was 25%/mo (range 0-42%), and incidence was 3.52/mo (range 0-13/mo). The cumulative mortality for those boas developing repetitive regurgitation (61 of 120) during the 23-mo epizootic was 51%. Hematologic findings included anemia and leukocytosis, with lymphocytosis, monocytosis, and azurophilia. Histologic evaluation of the gastrointestinal tract showed multifocal to diffuse lymphoplasmacytic inflammation with granuloma formation and positive immunohistochemical staining for chlamydial antigen. Electron microscopic evaluation of granulomas showed organisms consistent with Chlamydophila sp.

Mainly because of rheumatic fever,infective endocarditis (IE) is frequent in our countries and is associated with many diagnostic and therapeutic problems. We perform a retrospective study on 86 cases of IE hospitalized from December 1986 to November 1996. The prevalence of IE is 4.3% and there is a female predominance (the sex ratio is 0.56). The mean age is 26.45+/-13.22 years. 74.4% of the patients have of low socioeconomic status. The mean duration of inhospital stay is 54 days and the average diagnosis retardation is 35 days. The source of infection is found in 19 cases (15 sources are dental). The main clinical signs are: fever (63.9%), anaemia (67.4%) and weight loss (38.3%). The underlying heart disease is mainly due to rheumatic valve regurgitation (95.3%). The blood culture find microbialagent in 12.7%. Echocardiography reveals vegetations in 69.7% of patients. The main complications are : heart failure (47.6%) and stroke (33.7%). The mortality rate is high (30.7%). The treatment is only medical, none of the patients has surgical repair. This study shows that IE is frequent and is associated with many complications and a high mortality rate. These observations amphasize the importance of prevention of rheumatic fever.

Eastern equine encephalitis (EEE) was diagnosed in a flock of African penguins. Diagnosis was based on history and clinical signs and confirmed via serologic testing, virus isolation, reverse transcriptase-polymerase chain reaction (RT-PCR) assay, and histologic examination. Clinical signs in penguins included anorexia, behavior changes, depression, regurgitation, ataxia, recumbency, and seizures, and some penguins did not have any clinical signs. Mean +/- SD number of days that affected penguins had clinical signs was 12 +/- 5 days. Abnormalities initially detected on CBC included heterophilic leukocytosis and anemia; lymphocytosis and monocytosis were detected later. Plasma biochemical abnormalities included high activities of aspartate amino-transferase and creatine kinase, hyponatremia, hypochloremia, hyperglycemia, and high concentrations of globulin, triglycerides, and cholesterol. Mean +/- SD number of days required for resolution of CBC and plasma biochemical abnormalities was 67 +/- 24 days after the onset of clinical signs. Treatment consisted of supportive therapy. All penguins survived with the exception of one that was euthanatized; histopathologic findings were consistent with encephalitis. Results of RT-PCR assays performed on tissue from the right cerebrum of the penguin that was euthanatized were positive for EEE viral RNA. An inability to isolate virus several weeks after illness suggested successful viral clearance in recovered penguins. To the authors' knowledge, EEE infection in any penguin species has not been reported.

Hemolytic anemia after mitral repair and annuloplasty ring placement is very uncommon, and rarely described. The case is presented of a 53-year-old woman who developed severe mitral regurgitation and transfusion-dependent hemolytic anemia following mitral valve repair with a Carpentier-Edwards annuloplasty ring, which included transposition of chordae tendineae from the posterior leaflet to the anterior leaflet. Transesophageal echocardiography suggested that the transposed chordae tethered the anterior leaflet, causing malcoaptation of the leaflets. This resulted in central regurgitation divided by the chordae tendineae, producing two turbulent flow jets causing hemolysis. At reoperation, these chordae were removed and two longer Gortex neochordae to the anterior leaflet were placed with subsequent resolution of the anemia. To the authors' knowledge, this is the first case of hemolytic anemia caused by transposed mitral valve chordae tendineae from the posterior to the anterior leaflet.

Placental malaria is recognized as a common complication of malaria in pregnancy in areas of stable transmission, and, as a consequence, serious health problems arise for the mother and especially her baby [1]. Although malaria in pregnancy is a major factor associated with adverse perinatal outcome, the link between malaria and perinatal morbidity/mortality is less clear in areas with stable endemic malaria where pregnant women have acquired immunity [2]. Histological examination of the placenta is a predictor of fetal morbidity, as well as being the most sensitive detector of maternal infection [3]. Adverse perinatal outcome has been described as an important indicator of poor quality of obstetric care and social development [4]. A variety of adverse perinatal outcomes associated with placental malaria have been described, including low birth weight, preterm delivery, intrauterine growth retardation, fetal anemia, congenital malaria, and fetal mortality. The most common clinical features in 80 percent of perinatal cases are fever, anemia, and splenomegaly [5]. Other signs and symptoms include hepatomegaly, jaundice, regurgitation, loose stools, poor feeding, and, occasionally, drowsiness, restlessness, and cyanosis also can be seen [5,6].A review of studies that investigated these poor fetal outcomes associated with placental malaria in sub-Saharan Africa is presented here.

Spirocerca lupi is a nematode infesting the canine oesophagus, where it induces the formation of a nodule that may transform into a malignant sarcoma. The current, retrospective study compared the clinical presentation, haematology, serum albumin and globulin and radiology of benign cases (n=31) and malignant cases (n=31) of spirocercosis. Dogs with spirocercosis-induced sarcoma were significantly older (6.4+/-1.91 years) than benign cases (4.93+/-2.87). In the malignant cases there were significantly (p=0.03) more sterilized females (10/31) and fewer intact males (4/31) compared to 2/31 and 13/31, respectively, in the benign cases. Hypertrophic osteopathy was observed in 38.7% of malignant cases and in none of the benign cases (p=0.0002). Common clinical signs included weight loss, regurgitation, anorexia, pyrexia (T>or=39.5 degrees ), respiratory complications and salivation but did not differ in prevalence between groups. On haematology, the malignant group had significantly (p<0.05) lower haematocrit (0.34+/-0.08 vs. 0.41+/-0.07) and higher white cell count (31.6+/-27.83 vs. 17.71+/-13.18 x 10(3)microl(-1)), mature neutrophil count (26.06+/-26.08 vs. 12.23+/-9.96 x 10(3)microl(-1)) and thrombocyte count (493.15+/-151.61 vs. 313.27+/-128.54 x 10(9)microl(-1)). There were no differences in the mean corpuscular volume and immature neutrophil count. On radiology, the mass length was not significantly different, but the height and the width of the malignant masses were significantly larger (62.59+/-15.15 mm and 73.93+/-20.94 mm) compared to the benign group (46.43+/-23.62 and 49.29+/-25.56, respectively). Spondylitis was more prevalent in the malignant group (67.86% vs. 38.46%, p=0.03). Examining secondary pulmonary changes revealed significantly higher prevalence of bronchial displacement in the malignant group (52% vs. 17%, p=0.008). Hypertrophic osteopathy appeared to be a very specific but relatively rare (poor sensitivity) marker of malignancy. Female gender, anaemia, leukocytosis, thrombocytosis, spondylitis and bronchial displacement are significantly more common in malignant cases, but appear in benign cases as well. However, if found together in a specific case, they should increase the index of suspicion for malignancy in a diagnosed spirocercosis case.

A 10-year-old, intact, female yellow-naped Amazon parrot was examined because of anemia, lymphocytic leukocytosis, regurgitation, and weight loss. A positive fecal occult blood and monoclonal globulinopathy were present. A distended proventriculus and diffusely thickened loops of small intestine with irregular luminal surfaces were identified with contrast radiography and contrast computed tomography. A micro positron emission tomography scan was performed with (18)F-fluorodeoxyglucose. Diffuse intestinal T-cell lymphosarcoma was diagnosed based on histopathology and immunohistochemistry of full thickness small intestinal biopsies. The patient was treated with a multidrug chemotherapy protocol with little to no effect. Euthanasia was elected, and intestinal lymphosarcoma was confirmed on histopathology of necropsy intestinal samples; no other organs demonstrated neoplastic infiltration. To the authors' knowledge, no reports are currently available detailing the clinical presentation or diagnosis of diffuse intestinal T-cell lymphosarcoma in any avian species.

Mitral valvuloplasty which is currently the most popular surgical procedure in MVD may be complicated mostly by restenosis or valvular leakage. Hemolysis occurs less frequently and by far less commonly than in prosthetic valves but deserves to be known. Delay between valvuloplasty and hemolytic anemia occurrence may vary within a wide range (from some weeks to several years as in the case we report here). A careful follow-up of the patients who undergo MV repair will help to identify this complication which is related not to the size of the regurgitation flow but to the velocity of the jet. Surgery is the unique treatment of this kind of anemia.
