A proportionate analysis of cause of death in 1,401 commercial pressmen was initiated following a report of a cancer cluster in this group. The study found a significant elevated risk of all cancers [proportionate mortality ratio (PMR) = 127] and cancers of the lymphatic and hematopoietic system (PMR = 122), with non-Hodgkin's lymphomas responsible for much of the excess. Three deaths in the cohort were attributed to myelofibrosis, a rare disease associated with benzene exposure. A significantly elevated PMR was also detected for colorectal cancer (PMR = 171) and, among those employed 20 years or more, for cancers of the liver (PMR = 216) and pancreas (PMR = 162). No excess risk of bladder or lung cancer or leukemia was seen. Proportionate mortality analyses rarely show excess risk of both cancer and heart disease in a working population. Surprisingly, a significantly elevated risk of arteriosclerotic heart disease (PMR = 113) was found in this group. These findings indicate that solvent exposure may be associated with excess mortality risk in commercial pressmen.

Cat's eye syndrome is a very rare disease with many congenital anomalies. Until the end of 1983, 35 cases had been reported, but only 5 cases were associated with cleft palate, and only 1 patient was operated on. A 4-year-old male child had coloboma of the iridochoroid, cleft soft palate, hypertelorism with an antimongoloid slant of the eyes, epicanthal folds, hearing deficit, congenital heart disease (pulmonary arteriovenous fistula), mental and growth retardation, and a 47,XY + marker chromosome. The patient did not have anal atresia, preauricular skin tags, microphthalmia, depressed nasal bridge, or renal or skeletal anomalies. The operation was performed on his cleft soft palate when he was 2.5 years old.

Infective endocarditis is a rare disease in the general pediatric population. Nonetheless, children with congenital heart disease have a substantial lifetime risk for development of endocarditis, and recent advances in the management of these children should increase the number of patients who survive infancy and early childhood. During the 30-year period from 1950 through 1979, 50 cases of endocarditis in children were diagnosed at the Mayo Clinic. Of these 50 patients, 37 had congenital heart disease, and 8 were diagnosed as having endocarditis within 3 months after having undergone a cardiac surgical procedure. Nineteen patients died of the disease or its complications. The most common organism isolated at Staphylococcus aureus (19 patients), followed by viridans streptococci (14 patients). Children younger than 10 years of age experienced a particularly high mortality, as did patients of all ages with S. aureus infection. Any unexplained fever in a child with congenital heart disease deserves close investigation; if endocarditis is suspected, early empiric antibiotic therapy is indicated after appropriate culture specimens have been obtained. Moreover, localized bacterial infections in children at risk must be treated aggressively to prevent metastatic spread to the heart.

Myocardial sarcoidosis is not a rare disease in the UK and it is still probably under-diagnosed. A high index of suspicion in necessary for diagnosis of myocardial sarcoidosis, which should be thought of in any unusual form of heart disease for which there is no adequate explanation, particularly if there are serious rhythm changes or unexplained heart failure. Mitral systolic murmurs occur frequently. Histological proof of the aetiology should be sought. The heart is frequently massively involved when other organs have little involvement. Most of these patients present with cardiac symptoms or signs and the high incidence of sudden death is disturbing. The high rate of occurrence in East Anglia is noted, and merits further study. Treatment should be energetic where indicated--but its effects are difficult to assess. This study, representing the largest single source of information on this topic, continues in the hope of shedding more light on a sinister disease.

The idiopathic hypereosinophilic syndrome (HES) is a rare disease, characterised by persistent eosinophilia (> 1500/mm3), without underlying cause, provoking multiple organ system injury. Morbidity and mortality are mostly associated with the HES cardiopathy. Neurological signs are also frequent. Neurological dysfunction can be central (encephalopathy, organic psycho-syndrome) and peripheral (polyneuropathy, mononeuropathia multiplex, autonomic neuropathy, polymyositis). The encephalopathy is not always caused by distant thrombo-embolic events originating from the HES cardiopathy. We describe a patient with idiopathic HES central nervous system dysfunction, in the absence of cardiopathy. Furthermore we briefly discuss pathophysiological aspects, treatment modalities and the prognosis of the HES, in relation to our patient.

Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare disease, accounting for less than 3% of all congenital heart lesions. The cause of PA/IVS is unknown. We report the occurrence of two first cousins with PA/IVS, suggestive of autosomal dominant inheritance with incomplete penetrance. The study of such families should ultimately lead to the identification of the gene(s) that cause congenital heart disease.

There are currently no randomized and carefully controlled human trials to definitively prove that endocarditis prophylaxis is efficient. Furthermore, most cases of endocarditis are not attributable to a medical procedure. Thus, even with a high level of application of endocarditis prophylaxis only a minority of cases could be prevented. Endocarditis is a rare disease. On the other hand, its morbidity is increasing! In addition, infective endocarditis remains still a major medical concern because of its mortality between 5% and 76%. In addition, in up to 40% of all patients suffering from endocarditis one or more heart valves have to be replaced in the following 5 to 8 years. Without treatment endocarditis has a lethality of 100%. Therefore, there is worldwide agreement that endocarditis prophylaxis is necessary. Combining the recommendations of the German and the American Heart Association, as well as the results of the European consensus conferences, with newer insights into the pathophysiology of endocarditis the following aspects are elucidated: depending on their risk of endocarditis patients are allocated into 3 groups. In the first group there are patients with prosthetic cardiac valves, patients who suffered from previous endocarditis and patients with complex cyanotic congenital heart disease and surgically constructed shunts or conduits of the aorta and/or pulmonary circulation. In these high-risk patients the prophylactic regimen for dental, oral, respiratory tract procedures is oral amoxycillin. In genitourinary and gastrointestinal procedures ampicillin and gentamicin i.v. is recommended. In patients with mostly congenital cardiac malformations, acquired valvular dysfunction, hypertrophic obstructive cardiomyopathy and mitral valve prolapse or thickened leaflets and valvular regurgitation oral amoxycillin is recommended for all medical procedures (second group). The third group consists of patients with isolated secundum atrial defect, previous coronary bypass graft surgery, patients with cardiac pacemakers or defibrillators. In this patient cohort the individual risk of endocarditis is not higher than in the general population. Therefore, endocardits prophylaxis is not recommended.

Catecholamine-induced polymorphic ventricular tachycardia (CPVT), a rare disease that occurs in subjects without obvious organic heart disease, is characterized by episodes of syncope, seizures, or sudden death in response to physiologic or emotional stress. This report reviews evidence that a missense mutation in the CASQ2 gene is associated with autosomal-recessive CPVT.

Renal infarction is a rare disease which must be considered in any case of low back pain. The most frequent causes are related to emboligenic heart disease, renal artery fibrodysplasia or trauma. The authors report the second published case of idiopathic renal infarction. The diagnosis is usually suggested by contrast-enhanced abdominal CT scan, but is confirmed and refined by selective renal arteriography or CT angiography. Treatment may be medical or surgical depending on the severity of the lesions and the patient's general state. The therapeutic indications are discussed in the light of a review of the literature.

Peripartum cardiomyopathy (PPCM) is a rare cardiac disorder associated with high rates of mortality that occurs during the peripartum period. PPCM is recognized as a distinct entity, separate from preexisting cardiomyopathies that are worsened by the stressors of pregnancy. To date, its etiology is unknown, although several theories are under investigation in an effort to provide more information regarding available treatment options. A multidisciplinary review of PPCM held by the National Heart, Lung, and Blood Institute, in conjunction with the Office of Rare Disease of the National Institutes of Health, in April 1997 reviewed the current knowledge and developed recommendations for areas of further research and education about PPCM. Since then, there have been some promising research testing hypotheses regarding the etiology of PPCM and advancements in possible treatment options. However, despite these efforts, knowledge and treatment recommendations about PPCM are still generally unchanged, whereas mortality rates remain high. This article attempts to provide an updated, comprehensive review about PPCM and draw attention to areas in need of further research.
