Between August 1976 and July 1986, 110 burn patients over the age of sixty-five were admitted to the Burn Unit of Ruijin Hospital. The average extent of burn was 19.9% TBSA (0.5-90%), with 14.7% full thickness (0.5-90%). There was a significant difference surface and full thickness area (P less than 0.001) of total burn between non-survival and survival patients. The analysis of causes of death in elderly burn patients suggested that the preexisting cardiopulmonary diseases and inhalation injury appeared particularly important since pneumonia was considered as a primary cause of death in 13 patients, myocardial infarction in 2, congestive heart failure in 2. The resuscitation, early excision of deep burn wound and grafting, prevention and treatment of other complications, and nutritional supplement can decrease the mortality of elderly burn patients.

Among a total of 634,440 autopsy cases in "The Annuals of Pathological Autopsy Cases in Japan" from 1958 to 1984, 929 cases with nonspecific myocarditis were registered. The average incidence was 0.15%, fluctuating around 3- to 5-year intervals with a remarkable rise observed after 1974. The major complications in cases of myocarditis were pneumonitis, hepatitis or hepatic cirrhosis, pancreatitis, malignancies, lymphatic or thymic involvements. A clinicopathological study of 36 cases of myocarditis and 27 cases of postmyocarditic cardiomegaly indicated a classification of acute, subacute, healing and chronic or recurrent stages as well as dilatation-hypertrophy- and right ventricle-dominant types. Acute myocarditis was characterized by diffuse inflammatory cell infiltration and showed various types of arrhythmias and shock. Subacute myocarditis showed ventricular dilatation, edematous interstitium and severe congestive heart failure. Chronic myocarditis with dilatation and/or hypertrophy and irregular fibrosis included right ventricular involvement, endomyocardial disease, sick sinus syndrome in selected cases, congestive heart failure in most cases, and showed a male predominancy. Postmyocarditic cardiomegaly was similar to chronic myocarditis but showed more hypertrophy, preexcitation waves and prominent negative T waves in electrocardiography and sudden death.

In order to investigate the morbidity and mortality in individuals with Down syndrome(DS), we reviewed 237 cases of DS visiting our hospital in a ten-year period. There were 150 males and 87 females with age range from newborn to 25 years. The major illnesses included: 1) congenital heart disease (CHD), 42.6%; with endocardial cushion defect, ventricular septal defect, atrial septal defect and patent ductus arteriosus as the common types; 2) frequent or major respiratory tract infections, 34.2%; 3) summer fever, 5.5%; 4) major infective episodes other than pneumonia, 5.0%. Other diseases such as seizure disorder, gastrointestinal tract anomalies and thyroid dysfunction were also noted. There were 28 deaths of them and the causes of mortality were 1) CHD with congestive heart failure (CHD with CHF) and pneumonia (46.9%); 2) CHD with CHF and sepsis (10.7%); 3) CHD with CHF (14.3%) and 4) acute leukemia with infection (10.7%) respectively. Most of the mortality occurred during the first year of life, especially in patients with CHD. In our series, the one year survival rate was 93.6%; the result indicates that life expectancy in DS is much better than generally believed.

The Xe-133 ventilation pattern in congestive heart failure (CHF) was assessed using 24 inpatient ventilation/perfusion studies performed to rule out pulmonary embolism. Patients with histories of CHF, myocardial infarction (MI), and cardiomyopathy were included in the study. Frank pulmonary edema, pulmonary embolism, and other known lung diseases such as chronic obstructive lung disease, tumor, and pneumonia were excluded. Fifteen of the 24 patients had abnormal ventilation scans. Twelve of the 15 showed bilateral basal Xe-133 retention on washout; the remaining 3 showed diffuse, posterior regional retention. On perfusion scans, 14 of the 15 abnormal ventilation patients showed evidence of CHF such as inverted perfusion gradient, enlarged cardiac silhouette, or patchy perfusion, and all of them had a history of CHF or cardiac disease. Nine of the 24 patients had normal ventilation scans, including normal washout patterns. Seven of the nine had normal perfusion (p less than 0.01). Four of the nine normal ventilation patients had a history of cardiac disease or CHF but no recent acute MI. Bilateral basal regional Xe-133 retention, coupled with perfusion scan evidence of CHF such as inverted perfusion gradient, enlarged cardiac silhouette, and patchy perfusion pattern, appears to be a sensitive and characteristic ventilation/perfusion finding in mild or subclinical CHF.

It may be difficult to decide if respiratory/ventilatory failure in patients with emphysema has resulted from a reversible process, such as pneumonia, acute on chronic bronchitis or cardiac decompensation. Therefore, we favour early institution of mechanical ventilation. Intermittent mandatory ventilation (IMV), continuous positive airway pressure (CPAP) and the new modes of pressure support (PS) help the patient to recover the strength of his musculature. Measures for bronchodilatation, antibiotics and optimal nutrition (including fat calories) allow to successfully wean most patients from the respirator. The prognosis for survival, however, is very uncertain and in general not very promising.

We studied the clinical data and the autopsy findings of 88 patients to evaluate the importance of autopsies in Dutch nursing homes. The results of this retrospective analysis showed that 28% of the clinical diagnoses were not confirmed by autopsy. In 40% of the cases the direct cause of death was different from that expected by the clinician. In particulars, pneumonia and congestive heart failure relatively often caused diagnostic problems in a psychogeriatric nursing home. Autopsies appear to be useful to study causes of death, to verify the clinical diagnoses and to evaluate the results of treatment.

In some cases of congestive heart failure interlobar encysted pleural effusion may appear on X-ray film like a mass or tumor, and is therefore called phantom tumor or pseudo-tumor. This is a report on a 56-year old man who came to hospital admission with an assumed fungal pneumonia. The X-ray film showed a mass-like configuration in the right lung. In sputum analysis no pathogenic germs or fungi were found, no clinical or laboratory signs of infection were present. Unter intensive treatment of the underlying left heart failure the X-ray film changes vanished without administration of antimycotics.

Forty-five acutely ill, coughing patients, three with acute dyspnea and cardiomegaly, and 37 control subjects were placed in lateral decubitus positions for auscultation of their dependent lungs to determine if this maneuver would elicit inspiratory crackles, signs of pneumonia. In the upright position, auscultation of the lungs was normal in all control subjects and in lateral decubitus positions their dependent lungs revealed transient late inspiratory crackles in seven of the 37 (18.9%), and transient inspiratory peeling sounds in two others (5.4%). Thirteen acutely ill, coughing patients, free of prior cardiac and pulmonary diseases, had persistent late inspiratory crackles induced in one or both dependent lungs when placed in lateral decubitus positions. These dependent lungs also revealed increased numbers of crackles in three patients, late inspiratory squeaks in four, and wheezes in three others. In the upright position, auscultation of the lungs was normal in 10 of these patients, and a few basilar crackles were heard in three others. All of these abnormal findings cleared after treatment with antibiotics. Thirty-one of 32 acutely ill, coughing patients with bronchitis, sinusitis, or pharyngitis were free of induced crackles in dependent lungs in lateral decubitus positions. However, placement of two other patients in these positions appeared to have elicited the inspiratory crackles of chronic pulmonary disease and early congestive heart failure. These observations suggest that placement of acutely ill, coughing patients into lateral decubitus positions for auscultation of the dependent lungs may be a valuable maneuver for diagnosis of pneumonia.

The Swedish trial in old patients with hypertension (STOP-Hypertension) is a multicentre, randomized, double-blind study of beta-blockers/diuretics versus placebo in old hypertensives. Primary end-points are stroke and myocardial infarction (fatal and non-fatal) as well as other cardiovascular mortality. To evaluate the logistics of STOP-Hypertension, a pilot study was carried out. All patients aged 70-84 years in 31 centres were consecutively registered in a log-book. Altogether 4668 patients were screened: 41.5% had previously been treated for hypertension and 13.5% had blood pressures greater than or equal to 180/105 mmHg. Thus, 55% were 'hypertensive'. In all, 465 patients (18% of the 'hypertensive' patients) started a 3-month washout period (previously treated, n = 396) or a 4-week run-in period (previously untreated, n = 69) period. The most frequent reasons for not starting the run-in/washout were other indications for treatment with beta-blockers/diuretics (13%), unwillingness to participate (8%) or isolated systolic hypertension (4%). The pilot study was evaluated after 1 year: 89 patients (1.9%) had been randomized, 66 patients (1.4%) were still in the run-in/washout period and the majority of the remaining patients were not randomized because they had not reached the inclusion blood pressure (greater than or equal to 180 mmHg systolic and/or greater than or equal to 105 mmHg diastolic) following withdrawal of their antihypertensive medication. During the run-in/washout period there were few serious clinical events: one case of myocardial infarction, three patients had strokes (two fatal), 10 developed congestive heart failure, three tachyarrhythmia and two pneumonia (one fatal).(ABSTRACT TRUNCATED AT 250 WORDS)

Nosocomial pneumonia remains a challenging problem in critically ill patients in terms of both diagnosis and therapy. The clinical picture is often confusing; confounding factors such as congestive heart failure, ARDS, and interstitial lung disease may obscure the presence of pneumonia. Previous antimicrobial therapy or the presence of large numbers of colonizing organisms contribute to the difficulty of diagnosis. The use of sheathed fiberoptic bronchoscopy with quantitative culture and biopsy is probably the best initial invasive test when routine diagnostic methods fail; open lung biopsy remains the ultimate standard for diagnosis. Empiric therapy is often necessary and should be designed to treat organisms suspected of being the etiologic pathogens either on the basis of preliminary laboratory results (gram and acid-fast stains) or the clinical setting.
