In a patient with renal failure and shortness of breath, Q waves transiently appeared in the right precordial leads of the electrocardiogram (ECG) during episodes of hyperkalemia, without a substantial change in mean electrical axis. With restoration of the plasma potassium level to normal, R waves reappeared in these leads. It is concluded that the transient development of Q waves in the right precordial leads during hyperkalemia resulted from a hyperkalemia-induced conduction disturbance. Hyperkalemia, by affecting conduction in Purkinje fibers of ventricular muscle, or both, disturbed the normal sequence of septal and anterior wall depolarization and resulted in an ECG pattern that mimicked that of anteroseptal myocardial infarction. Clinically, hyperkalemia-induced conduction disturbances of this type must be included in the differential diagnosis of the ECG that suggests an anteroseptal myocardial infarction.

A 64-year-old man had slowly progressive thickening of the bulbar and palpebral conjunctiva of the right eye, followed by signs and symptoms of an upper respiratory infection. A biopsy specimen of the conjunctival lesions demonstrated granulomatous inflammation with eosinophils compatible with a diagnosis of Churg-Strauss syndrome (asthma, eosinophilia, vasculitis, and granulomatous inflammation with eosinophils). Subsequently, fever, shortness of breath, moderate renal failure, and anemia developed. Therapy with systemic corticosteroids and cyclophosphamide was instituted, with resolution of the systemic and ocular manifestations.

We report a case of severe acute obstructive airway disease 2 months after renal transplantation in a 16-year-old patient with Biedl-Bardet syndrome who was transplanted for end-stage renal failure secondary to cystic kidney disease. Symptoms of severe obstructive airway disease developed 2 months after transplantation under immunosuppression with prednisone, azathioprine, and tacrolimus. The patient did not develop signs of infection; progressive shortness of breath remained the only symptom for several weeks. After extensive diagnostic evaluation, bronchoalveolar lavage revealed Moraxella catarrhalis as the single infectious agent. After 3 weeks of appropriate antibiotic therapy, symptoms of obstructive airway disease were completely relieved. This atypical presentation of Moraxella infection in an immunocompromised host represents a rare complication of renal transplantation, especially in young patients. Special aspects such as frequency, diagnosis, differential diagnosis, and management of this rare complication of renal transplantation in a pediatric patient are discussed.

Thirty-four consecutive patients were hospitalized with diagnosis of severe Babesia infection over the course of 13 years. The average time from onset of symptoms to diagnosis was 15 days. When compared with uninfected febrile control patients, affected patients complained significantly more often of malaise, arthralgias and myalgias, and shortness of breath (P<.05), and they more often had thrombocytopenia and abnormal liver function (P<.05). Forty-one percent of patients with Babesia developed complications such as acute respiratory failure, disseminated intravascular coagulation, congestive heart failure, and renal failure. Analysis of data revealed that complicated babesiosis was more commonly associated with the presence of severe anemia (hemoglobin level <10 g/dL; P=.01) and higher parasitemia levels (>10%; P=.08). Patients were treated with a combination of drugs that included clindamycin, quinine, atovaquone, or azithromycin. Despite treatment, parasitemia persisted for an average of 8.5 days (range, 3--21 days). Exchange transfusion was performed for 7 patients, and it effectively reduced the high levels of parasitemia. Three patients died. Improved outcomes may result with prompt recognition and treatment of babesiosis.

A 61-year-old woman who was a New York City hospital employee developed fatal inhalational anthrax, but with an unknown source of anthrax exposure. The patient presented with shortness of breath, malaise, and cough that had developed 3 days prior to admission. Within hours of presentation, she developed respiratory failure and septic shock and required mechanical ventilation and vasopressor therapy. Spiral contrast-enhanced computed tomography of the chest demonstrated large bilateral pleural effusions and hemorrhagic mediastinitis. Blood cultures, as well as DNA amplification by polymerase chain reaction of the blood, bronchial washings, and pleural fluid specimens, were positive for Bacillus anthracis. The clinical course was complicated by liver failure, renal failure, severe metabolic acidosis, disseminated intravascular coagulopathy, and cardiac tamponade, and the patient died on the fourth hospital day. The cause of death was inhalational anthrax. Despite epidemiologic investigation, including environmental samples from the patient's residence and workplace, no mechanism for anthrax exposure has been identified.

The patient, a 78-year-old Asian male, was brought to the hospital because of acute shortness of breath that had progressively worsened over the course of the day. He complained of a nonproductive cough and claudication after walking 1 block. His past medical history was significant for mild renal insufficiency (serum creatinine 1.5--2.0 mg/dl), the etiology of which was never explored. Although there was a recent history of mild to moderate hypertension, at presentation his blood pressure was noted to be 240/118 mm Hg in both arms. His physical exam at the time of admission was remarkable for grade II hypertensive retinopathy, an S4 gallop, periumbilical systolic bruits, audible femoral arterial bruits and absent distal lower extremity pulses. Initial complete blood count, serum electrolytes and cardiac enzymes (including lactate dehydrogenase) were normal. His blood urea nitrogen and serum creatinine concentrations were 51 and 3.6 mg/dl, respectively, and his urinalysis showed 1+ protein (both by dipstick and sulfasalicylic acid) with a "benign" sediment (0--1 WBC/HPE, 1--2 RBCs/HPF) with occasional granular casts. His electrocardiogram, apart from demonstrating left ventricular hypertrophy with secondary ST-T wave abnormalities, showed no acute changes; his chest X-ray demonstrated cardiomegaly and pulmonary vascular congestion. He was intubated and subsequently treated with increasing parenteral doses of furosemide (40--240 mg) and a nitroglycerine drip (up to 15 mcg/min). Over the course of the first 48 h, his blood pressure was gradually lowered to 170/100 mm Hg. His urine output increased from 20 ml/h to 125/ml/h, and his respiratory status improved, allowing him to be extubated. In spite of adequate control of his blood pressure in the ensuing days (150--170/80--90 mm Hg), his renal function continued to deteriorate. Renal sonography (without Doppler) demonstrated a right kidney of 9.6 cm and a left kidney of 9.3 cm in length without evidence of hydronephrosis. Both kidneys were noted to be echogenic. Assays for antinuclear antibodies and antineutrophilic cytoplasmic antibodies were negative, and the patient's serum complement levels were normal. For several days after his admission, his serum creatinine gradually rose to 10.7 mg/dl, and hemodialysis was initiated for uremic encephalopathy. Because of the high index of suspicion for renal artery stenosis as the case of both his hypertension and renal failure, a renal angiogram was performed. It revealed a 90% occlusion of the right renal artery with ostial involvement and a 70% occlusion of the left renal artery; both kidneys had poor distal renal vasculature and there was marked atherosclerotic disease of the aorta. After being hemodialyzed for 3 treatments, his renal function began to improve spontaneously. His serum creatinine returned to 3.4 mg/dl, and a subsequent 24-hour urine demonstrated a creatinine clearance of 20 ml/min and an excretion of 1.2 g of protein. Following his discharge from the hospital, his renal function remained unchanged for 3 years, and his blood pressure was easily controlled on monotherapy with a long-acting calcium channel blocker. He recently died from pneumonia.

We report the case of a 33-years-girl with SCA and severe PH. She developed six month before admission, non productive cough and dyspnea. Physical examination at admission revealed shortness of breath and right heart ventricular failure. Electrocardiography showed sinus rhythm and an incomplete left bundle branch block. Chest roentgenography revealed cardiomegaly with cardiothoracic index at 0.66 and pulmonary infiltrates. Laboratory tests revealed an anemia with hemoglobin of 7.1 g/dl, white blood cell count of 12,500/mm, moderate renal failure (cretininemia = 178 mumol/l) and hypoxemia with oxygen pressure of 60 mmHg. Hemoglobin electrophoresis revealed on heterozygous SCA. Echocardiography revealed dilatation of right heart cavities and a systolic pulmonary artery pressure of 60 mmHg. A perfusion lung scintigraphy demonstrated multiple subsegmental perfusion defects. PH is a common complication of adult patients with SCA. Appropriate therapies and strategies for prevention of PH in SCA are unknown. Further research exploring therapies such as oxygen, nitric oxide, prostacyclin and hydroxyurea are indicated.

A 71-year-old man with bilateral renovascular disease was admitted to Hamamatsu University hospital because of appetite loss and acute shortness of breath due to acute pulmonary edema (APE) with accelerated hypertension and renal failure. Hypertension and APE were controlled by an angiotensin converting enzyme inhibitor (ACEI) and four sessions of hemodialysis with reduction of 1.8 kg bodyweight. Renal function was later stabilized and the patient required no ACEI or hemodialysis. A trial of right renal angioplasty 1 month after admission failed and renal function deteriorated (serum creatinine 7.1 mg/dL) with accelerated hypertension, gain of bodyweight and APE. Even after four sessions of hemodialysis with adequate reduction of bodyweight, APE was not controlled, but it rapidly improved after administration of an ACEI, without major bodyweight change. As no apparent cardiac dysfunction was evident, APE might have been caused by a direct action of angiotensin II on hyperpermeability in pulmonary capillaries. Blocking of angiotensin II should be considered in such patients even after introduction of hemodialysis.

Thrombotic microangiopathy (TMA) is a recognized complication of malignant hypertension (HTN). Such patients have blood pressures > or = 200/140 mmHg but the condition is defined by the presence of papilledema and is frequently complicated by acute renal failure. Here we report two patients with severe HTN (systolic > or = 180 mmHg or diastolic > or = 120 mmHg), TMA, thrombocytopenia, renal failure, and, in one case, neurological changes (4 of 5 manifestations of the TTP pentad). A 50-year-old male with HTN presented with blurred vision, dizziness, headache, confusion, renal failure, and a TMA (PLT = 39 x 10(9)/L and LD = 2,781 normal <600 U/L). On presentation, BP was 214/133 mmHg and an ophthalmic exam demonstrated no papilledema. With HTN control over 7 days, his platelet count rebounded (220 x 10(9)/L), LD declined (1,730 U/L), and mental status improved. A 60-year-old female with diabetes, HTN, Lupus erythematosus, mild chronic anemia, and thrombocytopenia presented with abdominal pain, shortness of breath, renal failure, and a TMA (PLT = 83 x 10(9)/L and LD = 2,929 U/L). Blood pressures were 180-210/89-111 mmHg and ophthalmic exam demonstrated no papilledema. With HTN control over 8 days, her platelet count rebounded (147 x 10(9)/L), and LD declined (1,624 U/L). Although in both cases a diagnosis of TTP was considered because of overlap with the classic diagnostic pentad, neither received plasmapheresis. TTP is a diagnosis of exclusion, where there is no other likely diagnosis to explain the TMA. In cases of severe HTN (with or without papilledema), the diagnosis of TTP should be held in abeyance until the effect of HTN control can be assessed.
