The approach to a patient with acute polyuria and hypernatremia: a need for the physiology of McCance at the bedside.

We present a case to illustrate the importance of emphasizing elementary physiology to deduce the basis for the acute onset of polyuria and hypernatremia. An imaginary consultation with Professor McCance is utilized to illustrate how a clinician-physiologist would have explained why these abnormalities developed and how they should have been treated. His approach began with a consideration of the most impressive abnormality. His analysis relied heavily on deductions and the anticipation of the expected responses to a stimulus in quantitative terms. The goals of therapy became evident after he performed mass balance calculations. Professor McCance would not understand why modern clinicians abandoned this form of analysis.

Long-term prognosis of acute pulmonary oedema--an ominous outcome.

BACKGROUND: Acute pulmonary oedema (APOE) is a major health problem, leading to poor hospital and long-term outcomes. There is a relative paucity of studies describing prognosis of consecutive unsolicited patients diagnosed with APOE and hospitalized in internal medicine departments. AIMS: To describe the clinical profile and outcome (in hospital and 1-year prognosis) of successive unselected patients with APOE, in a prospective observational study. METHODS AND RESULTS: The study population included 150 consecutive unsolicited patients (90 men, 60 women; median age 75 years) with APOE all hospitalized in an internal medicine department, in a 900-bed care centre. Ischaemic heart disease (IHD), hypertension and diabetes were present in 85%, 70% and 52% of patients, respectively. The most common precipitating factors for APOE included high blood pressure (29%), rapid atrial fibrillation (29%), unstable angina pectoris (25%), infection (18%) and acute myocardial infarction (MI; 15%). Eighteen patients (12%) died in hospital, with 82% of these deaths attributed to cardiac pump failure. Predictors for an increased in-hospital mortality included: diabetes (P<0.05), orthopnoea (P<0. 05), echocardiographic finding of depressed global left ventricular systolic function (P<0.001), acute MI during hospital stay (P<0.001), hypotension/shock (P<0.05), and the need for mechanical ventilation (P<0.001). After a median hospital stay of 10 days, 132 patients were discharged home. The 1-year mortality was 40%. Only the presence of pleural effusion was found as a predictor for 1-year mortality. CONCLUSION: Most patients with APOE in this study are elderly, and have IHD, hypertension, diabetes and a previous history of APOE. The overall mortality is high (in-hospital, 12%: 1-year, 40%). Left ventricular dysfunction was associated with high in-hospital mortality, but not with long-term prognosis.

Echocardiography in nonbacterial thrombotic endocarditis: from autopsy to clinical entity.

Bacteria-free verrucae, frequently termed "non-bacterial thrombotic endocarditis," have been recognized in autoimmune disorders as well as in neo-plastic diseases. The antemortem diagnosis of non-bacterial thrombotic endocarditis is rare, and most existing data result from postmortem examinations. In 3 prospective echocardiographic studies we found typical cardiac valvular lesions in patients with primary antiphospholipid syndrome, myelo-proliferative disorders, and solid malignant tumors. Cardiac lesions associated with these 3 different entities had common echocardiographic appearance and correlated positively with thromboembolic events. The possibility of common pathogenesis is suggested, and clinical significance is discussed.

Left hydronephrosis caused by Crohn disease successfully treated conservatively.

We report the case of a 35-year-old man who presented with fever, diarrhea, and a left abdominal mass. Diagnostic studies confirmed Crohn disease and revealed an abdominal mass obstructing the left ureter with hydroureter and hydronephrosis. The patient was successfully treated conservatively, with corticosteroids and mesalamine, A review of the literature indicates a predominance of right ureteral involvement in Crohn disease, associated with a high incidence of ileocecal disease. Most of these patients were treated surgically, with resection of ileocecal lesion and/or ureterolysis. Ureteral obstruction as a complication of Crohn disease is discussed, with emphasis on conservative treatment.

Prospective evaluation of pulmonary edema.

OBJECTIVES: To describe the clinical profile and hospital outcome of successive unselected patients with pulmonary edema hospitalized in an internal medicine department. DESIGN: Prospective, consecutive, unsolicited patients diagnosed with pulmonary edema. SETTING: An internal medicine department in a 900 tertiary care center. PATIENTS: A total of 150 consecutive unselected patients (90 males, 60 females; median age, 75 yrs). RESULTS: Ischemic heart disease, hypertension, various valvular lesions and diabetes mellitus were present in 85%, 70%, 53%, and 52% of patients, respectively. Acute myocardial infarction at admission was observed in 15% of patients. The most common precipitating factors associated with the development of pulmonary edema included: high blood pressure (29%), rapid atrial fibrillation (29%,) unstable angina pectoris (25%), infection (18%), and acute myocardial infarction (15%). Twenty-two patients (15%) were mechanically ventilated. Eighteen patients (12%) died while in the hospital, and the cause of death was cardiac pump failure in 82%. The median hospital stay was 10 days. Predictors for increase rate of in-hospital mortality included: diabetes (p<.05), orthopnea (p<.05), echocardiographic finding of moderate-to-severely depressed global left ventricular systolic function (p<.001), acute myocardial infarction during hospital stay (p<.001), hypotension/shock (p<.05), and the need for mechanical ventilation (p<.001). CONCLUSIONS: Most patients with pulmonary edema in the internal medicine department are elderly, having ischemic heart disease, hypertension, diabetes, and a previous history of pulmonary edema. The overall mortality is high (in-hospital, 12%) and the predictors associated with high in-hospital mortality are related to left ventricular myocardial function. The long median hospital stay (10 days) and the need for many cardiovascular drugs, impose a considerable cost in the management and health care of these patients.

Cardiovascular adverse drug reaction associated with combined beta-adrenergic and calcium entry-blocking agents.

Numerous studies have shown a beneficial effect of combination therapy with beta-blockers and calcium antagonists in patients with anginal syndrome and/or hypertension. However, because both agents exert a negative chronotropic effect, their combined use may cause bradyarrhythmias with resultant symptoms of cerebral, coronary, and systemic hypoperfusion. We describe our clinical experience with patients who had cardiovascular adverse drug reactions (CVADRs) with combination therapy. This prospective study included 26 patients who had CVADRs among 2,574 admissions during a 2-year period. The study group included 14 men and 12 women with a median age of 73 years. Various combinations of calcium antagonists and beta-blockers were associated with the CVADRs. The most frequent pharmacologic combination was diltiazem plus propranolol. The CVADRs were the cause for hospital admission in 10 patients, an associated cause in nine patients, and developed during hospitalization in seven patients. Cardiac bradyarrhythmias were found in 22 patients. These rhythm abnormalities resolved within 24 h after discontinuation of the offending drugs. Temporary transvenous pacemaker insertion was necessary in only one patient with complete atrioventricular block. Twenty-two patients recovered, two patients died of pump failure not associated with CVADRs, and in two patients, the CVADRs contributed to the patients' death. CVADRs are not uncommon in elderly patients with ischemic heart disease and/or hypertension treated with the concomitant use of calcium antagonist and beta-adrenergic blocking drugs. Use of calcium antagonist plus beta-blocker may unpredictably cause serious hemodynamic events, marked suppression of sinus node activity, and prolongation of atrioventricular conduction in some patients. Enhanced therapeutic monitoring may be warranted when calcium antagonists are combined with beta-blockers.
