Holter monitoring was performed on days 1-2, 6-9 of the disease and on days 30-60 before their discharge from hospital in 54 patients with acute gross myocardial infarction. The presence of cardiac rhythm and conduction disturbances and ischemic ST-segment depression or elevation was evaluated. The patients having frequent and prolonged (more than 3 hours during a 2-day follow-up) showed a complicated course of the disease: recurrent pain syndrome, signs of heart failure, prolonged cardiac arrhythmias, and fatal outcomes. The patients with uncomplicated acute myocardial infarction had no long-term episodes of ischemic ST-segment depression or elevation, as recorded by Holter monitoring in the first 2 days of the disease. On days 6-9 no cardiac rhythm and conduction disturbances that had been observed in them were recorded. The patients in whom the episodes of silent myocardial infarction remained on their discharge exhibited a high (35%) incidence of myocardial infarction recurrence within a year.

We have treated with intravenous iloprost twelve patients suffering from cardiac insufficiency compensated under oral digoxin (NYHA class II) associated with severe limb ischaemia due to arterial insufficiency. Our aim was to study its possible interaction on digoxin levels and to evaluate the long-term efficacy of iloprost. Although iloprost slowed the digoxin absorption by approximately one hour, we found no clinically significant difference between the digoxin pharmacokinetic data before and during treatment by iloprost. Moreover, 11 out of the 12 patients had a good clinical fate after the treatment, which persisted at 6 months. The pain disappeared in 4 and diminished in 7; and all skin ulcers healed. This improvement has lasted up to two and a half years in two patients. The clinical tolerance of iloprost was acceptable despite frequent headache and flushing associated with hypotension and nausea. We conclude that iloprost seems to be a very promising treatment of severe limb ischaemia when no intervention on the proximal arteries is possible. The patients on digoxin can continue their treatment without dose alteration while starting on iloprost.

Endovascular infections that involve the right side of the heart present their own unique etiologies, pathophysiologies, clinical manifestations, and therapeutic issues. The pathology of the vegetations of right-sided endocarditis is identical to that of left-sided endocarditis. These vegetations are irregular, friable masses of varying size the contain platelets, fibrin, RBCs, and microorganisms. These lesions serve as a nidus for deep-seated infection and produce sustained bacteremia. Right-sided endocarditis occurs in 5% to 10% of all cases of endocarditis. The most common predisposing factors are IV drug abuse and congenital heart disease. S. aureus is the most common pathogen. The clinical manifestations include fever, chills, rigor, dyspnea, pleuritic pain, productive cough, and hemoptysis. The cardiac manifestations can be notably absent early in the course of the disease, with only 20% of patients initially showing a significant murmur on physical examination. Peripheral embolic lesions can be seen. Echocardiography is helpful in identifying vegetations on the tricuspid valve in a significant proportion of patients. The chest radiograph is characteristic, showing features typical of multiple septic pulmonary emboli. The radiograph shows multiple, small, fuzzy, patchy, peripherally located densities that can change rapidly on serial films. Complications of right-sided endocarditis include pulmonary infarction, pulmonary abscess, progressive right-sided heart failure, and renal abnormalities. The treatment of right-sided endocarditis includes prolonged therapy, with high doses of IV bactericidal antibiotics. Four weeks of antibiotic therapy is generally required, but newer regimens using combination antibiotic therapy can be successful in sensitive strains of viridans group streptococci and S. aureus. Surgical resection of the tricuspid valve is recommended for organisms that do not respond to initial antibiotic therapy, fungal endocarditis, resistant relapsing organisms, or coexistent infection with S. aureus and P. aeruginosa. The prognosis of right-sided endocarditis is generally favorable when compared with left-sided endocarditis. The prognosis is especially favorable in IV drug abusers infected with S. aureus. Patients infected with fungal organisms, Pseudomonas or Serratia, have a worse prognosis. The presence of significant right-sided heart failure also imparts a worse prognosis.

A 47-year old female had a fever about 39 degrees C of unknown origin for 2 days. Soon she developed pain in the bilateral lower extremities followed by gait disturbance and vesicorectal disorder. Prednisolone was administered with an improvement. However, she developed paresthesia in the upper extremities 1 month later, and then gradually paraplegia another 5 month later. Nystagmus, painful tonic spasm, facial spasm, and visual disorder also appeared. These symptoms repeatedly exacerbated and remitted with administration of prednisolone. We examined this patient at age 53, CBC, blood chemistry, urinalysis, ECG and chest X-ray were normal. Serum IgG and IgA level were decreased. CSF protein content and IgG level were remarkably increased. EEG showed diffuse theta activities. MRI studies revealed high intensity signals in the putamen, deep frontal and periventricular white matter region. Pulse therapy of methylprednisolone was performed effectively for several times. She died of respiratory and heart failure 6 years after the onset. Autopsy revealed bilateral continuous cystic lesions along the lateral ventricles extending from the frontal tips of anterior horns to the occipital tips of posterior, and further, to the temporal tips of lateral horns; the caudate-callosal angeles (Wetterwinkel) were more severely and widely affected bilaterally. There were also old and fresh demyelinated lesions scattered in the cerebral white matter, brainstem, cerebellum, and spinal cord. Although this case is considered to have typical MS from clinical and pathological findings, there have been only a few reports of MS with such continuous cystic lesions in the cerebral hemispheres as seen in this case.

The purpose of the present study was to measure plasma levels of atrial natriuretic peptide (ANP) in patients with acute myocardial infarction without heart failure, and also to assess the temporal sequence of changes of plasma ANP during the first hours of recovery from myocardial infarction. The study was performed in 22 patients who were admitted to the Intensive Care Unit with the diagnosis of acute myocardial ischaemia that had an evolution of less than 6 h. Blood samples were drawn on admission and at 1, 8, and 24 h, and plasma concentrations of ANP, renin, aldosterone, epinephrine, norepinephrine and vasopressin were measured. Compared with control subjects, on admission patients showed increased plasma levels of ANP, as well as increased plasma renin activity (PRA), aldosterone, norepinephrine, epinephrine, dopamine, and antidiuretic hormone (ADH). ANP, but not renin or aldosterone plasma values, decreased with time, and there was a significant correlation between ANP and time after onset of pain. No increase in plasma creatinine was observed during the hospital stay, and the patients showed a negative fluid balance. No relationship was found between the location or extension of the infarction, or morphine treatment and ANP plasma levels. The high levels of ANP seem to counteract the haemodynamic and fluid-retention effects of the vasoconstrictive factors released after myocardial infarction.

A pair of 37-year-old identical twins with diabetes mellitus are described. One of the brothers was admitted for heart failure without pain, and autonomic neuropathy was found. The clinical diagnosis was inferior myocardial infarction with anteroseptal healed myocardial infarction. Cardiac catheterization revealed triple coronary vessel involvement. The diagnosis was confirmed at autopsy after sudden death. The other brother was also examined by cardiac catheterization, which revealed total right coronary occlusion and hypokinesis of the wall. There had been no previous pain nor upper body discomfort until that time in either twin. Thus, genetic factors should possibly be considered in the genesis of asymptomatic or silent myocardial infarction.

Two patients are presented in whom percutaneous radiofrequency spinal rhizotomy was complicated by contralateral paresis. Both patients were elderly and suffered from cardiac failure, chronic obstructive respiratory disease, and generalized vascular disease. Investigation of the paresis indicated a contralateral ischaemic cord lesion. It is suggested that local haemodynamic changes induced by heat-mediated rhizotomy may compromise oxygen delivery to the adjacent cord, especially in the presence of pre-existent cardiovascular disease.

Electrocardiographic signs of changes in the myocardium were detected in 93.2 percent of 74 patients with malignant maxillofacial tumors; this was due to the presence of coronary disease, myocardial dystrophy, essential hypertension, respiratory abnormalities. The development and progress of these shifts much depended on radiotherapy and chemoradiotherapy of the tumors. The most frequent findings were deviations in the end section of the ventricular complex, reflecting the metabolic and ischemic changes in the myocardium, associated with a rise in radiation and polychemotherapy dosage. Extracoronarogenic myocardial lesions and coronary disease progression were clinically characterized by augmentation of cardiac insufficiency and various arrhythmias with mild pain syndrome. These specific clinical and electrocardiographic features of myocardial involvement should be borne in mind when choosing and carrying out radio- and polychemoradiotherapy of patients with maxillofacial tumors.

Ultrasonography revealed a renal tumour (4 x 4 cm) in a 67-year-old man with right-sided lumbar pain and macrohematuria. In addition he had marked nocturnal dyspnoea with dry cough. He had lost about 10 kg in weight. On admission he had atrial fibrillation with an irregular ventricular rate (140 beats/min) and engorgement of the neck veins. Two-dimensional echocardiography, undertaken because of signs of increasing heart failure and a fall of systolic blood pressure to below 100 mm Hg, demonstrated a space-occupying lesion in the right ventricle, 4 x 2 x 1 cm, indicating an intracardiac thrombus or solid tumour. The heart failure continued to worsen, despite treatment with cardiac glycosides, verapamil and diuretics. Hence an exploratory thoracotomy was performed. This revealed an intracardiac tumour which had markedly displaced the right ventricular inflow tract and infiltrated the entire myocardium, but not the tricuspid valve. As much of the tumour as possible was resected, but the patient died postoperatively of heart failure. The intracardiac tumour proved to be a metastasis from the papillary carcinoma of the kidney. This had infiltrated the renal capsule and pelvis and invaded the branches of the right renal vein.

Postoperative use of as-needed intramuscular narcotics is potentially hazardous in frail elderly patients. Patient-controlled analgesia (PCA) allows patients to self-administer small boluses of narcotic, allowing better dose titration, enhanced responsiveness to variability in narcotic requirements, and reduction in serum narcotic level fluctuation. Although theoretically useful, this method has not bee well studied in the elderly or medically ill. A prospective controlled trial among 83 higher-risk elderly men after major elective surgery compared PCA containing morphine sulfate with intramuscular morphine injections as needed (mean [+/- SD] age, 67.4 +/- 5.6 vs 67.0 +/- 6.3 years). Subjects had a variety of medical illnesses, including chronic lung disease (57%), coronary artery disease (43%), heart failure (13%), and liver disease (12%). Preoperative and postoperative assessments included chest roentgenograms; daily mental status and pulmonary function testing; twice-daily serum morphine levels; and oxygen saturation values, linear analogue pain and sedation scores, and vital signs every 2 hours. Care was taken to optimize narcotic administration in control subjects as well as PCA subjects. Analgesia was significantly improved by PCA (3-day mean pain score, 40.5 +/- 18.0 vs 32.5 +/- 15.0), without an increase in sedation. Significant postoperative confusion (18% vs 2.3%) and severe pulmonary complications (10% vs 0%) occurred significantly more frequently in intramuscular-treated controls. Patient-controlled analgesia was quickly mastered by most patients; no major problems referable to its use occurred. Patients who had previously received intramuscular injections reported that PCA was easier to use and provided better analgesia. Serum morphine levels showed significantly less variability on postoperative day 1 with PCA, compared with intramuscular injections. We conclude that PCA is an improved method of postoperative analgesia in high-risk elderly men with normal mental status, compared with as-needed intramuscular injections.
