Incidence and type of postoperative complications were prospectively analyzed in 2280 patients undergoing gastrointestinal surgery. 6.6% had one or more pulmonary complications requiring therapeutic intervention (2.3% pneumonia, 1.6% drained pleural effusions, 1.2% atelectases). Based on univariate and logistic regression analyses, the following parameters constitute high-risk patients with regard to pulmonary complications: Elective surgery (4.3%, 61/1428): anemia (7.2% pulmonary complications), pathological blood gas analysis (9.8%), preoperative hospitalization greater than 1 week (6.3%), blood loss under operations greater than 1000 ml (10.5%), length of the operation greater than 3 h (9.7%); emergency surgery (10.4%, 89/852): upper gastrointestinal operation (16.2%), age greater than 75 (19.9%), ASA IV/V (28%), anemia (19.6%), chronic bronchitis (19%), pathological blood gas analysis (26.6%), diabetes (16.5%), heart failure (18.2%), blood loss under operation greater than 1000 ml (24.3%), length of the operation greater than 2 h (15.4%). These results allow to distinguish between different levels of pulmonary risk.

Pulmonary hemosiderosis (PH), a rare pathology, usually occurring during infancy and childhood, is characterized by numerous and repeated intra-alveolar bleedings, interstitial iron build-up with consequent progressive fibrosis and severe anemia. PH can be basically divided into 3 different categories: Primitive or idiopathic, involving a primitive deficit of antioxidizing enzymes in the erythrocytes in genetically predisposed subjects; Secondary, subsequent to chronic pneumopathy or cardiopathy; Associated with various pathologies including collagenopathies, glomerulonephritis, myocardiopathies, diabetes, steatorrhea, tireotossicosis. A particular type of Pulmonary Hemosiderosis, associated with allergy to cow's milk, has been described for the first time by Heiner. We present in this paper our personal experience of a young patient suffering from pulmonary hemosiderosis induced by cow's milk protein.

The clinical features of congestive heart failure in the elderly were investigated in 104 patients (57 males, 47 females, mean age of 79.2). Patients were divided into two subgroups, the readmission group, 33 patients who were readmitted within 6 months after discharge, and the non-readmission group. Chief complaints were dyspnea, edema, chest pain, loss of appetite, chest compression, and palpitation. Heart failure was caused by infection, myocardial ischemia, arrhythmia, inappropriate drug usage including poor drug compliance, the use of beta-blockers, excessive intake of sodium, and anemia. Careful use of drug was essential especially in the readmission group. Major underlying heart disease were ischemic heart disease (39.4%), valvular disease (26.9%), hypertensive heart disease (9.6%), with cardiomyopathy, congenital heart disease seen in the minority. There was no statistically significant difference in underlying heart diseases between the two groups. Supraventricular arrhythmias such as atrial fibrillations, paroxysmal atrial fibrillations, paroxysmal supraventricular tachycardias, and premature atrial contractions were noted in 85.3% of the cases. Drugs for treatment were diuretics, digitalis, isosorbide dinitrate, calcium antagonists. ACE inhibitors and alpha-blockers were also used, showing that vasodilators were more extensively used than before. The major complications were hypertension (39.4%), renal dysfunction (27.9%), cerebrovascular disease (26.9%), diabetes mellitus (16.5%), arteriosclerosis obliterans (7.7%). Renal dysfunction, arteriosclerosis obliterans was seen significantly more frequently in the readmission group. The prognosis at one year after admission was significantly worse in the readmission group. In summary, the major underlying diseases were ischemic heart disease, valvular disease, and hypertensive heart disease. Ischemic heart disease was seen more frequently than in previous investigations at our hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-one abdominal fascial wound dehiscences occurred in 2,761 patients undergoing major abdominal surgery during a 5-year period (1%). Twenty-two specific local and systemic risk factors were analyzed and compared with the risk factors of a control group of 38 patients undergoing similar procedures without dehiscence. Through multivariate analysis, each factor was assessed as an independent statistical variable. Significant factors (p less than 0.05) were found to include age over 65, wound infection, pulmonary disease, hemodynamic instability, and ostomies in the incision. Additional systemic risk factors that were found to be significant included hypoproteinemia, systemic infection, obesity, uremia, hyperalimentation, malignancy, ascites, steroid use, and hypertension. Risk factors not found to be important independent variables included sex, type of incision, type of closure, foreign body in the wound, anemia, jaundice, and diabetes. When dehiscence and control groups were combined, 30% of patients with at least five significant risk factors developed dehiscence, and all the patients with more than eight risk factors developed a wound dehiscence. There was an overall mortality of 29%, which was directly related to the number of significant risk factors. The co-existence of 9 risk factors portended death in one third of the patients, and all the patients with more than 10 risk factors died.

Age-related changes in clinical features of 182 patients diagnosed as having pulmonary tuberculosis from positive culture results of tubercle bacilli were extensively investigated. The percentage of cases detected using mass miniature radiophotography (MMR) was highest in the patients aged 30-39 years, and then decreased with increasing age. It was only 16-19% in those aged 60 years or older. Certain conditions, such as cardiovascular diseases, hypertension, diabetes mellitus, malignancy and other lung diseases, were common in the patients aged 60 years or older. Systemic symptoms, including weight loss and anorexia, and physical abnormalities, including fever and crackles, were common in these patients. Anemia tended to be predominant in the patients aged 60 years or older. The middle/lower lobes were involved more frequently in these patients, in whom the disease distribution was more than one lobe, or disseminated. Positive smear results and negative anergy were more frequently noted in the patients aged 60 years or older. The mortality from tuberculosis in these patients was 4% (7 cases). Although gastrointestinal disorder due to antitubercular drugs was more common in the patients aged 80 years or older, eosinophilia was less frequently observed. Today, improved conditions, better sanitation and the development of new chemotherapeutic agents have contributed to the decline of tuberculosis among the general population. But more efficient procedures that allow the early detection or diagnosis of pulmonary tuberculosis in the elderly should be achieved as soon as possible.

The relationship between outcome and hemoglobin (Hgb), oxygen extraction ratio (ER), history of cardiac, renal, pulmonary, and/or hepatic disease, diabetes, malignancy, sepsis, hypertension, and active bleeding was analyzed in 47 patients with severe anemia (Hgb less than 7.0 gm/dl, mean = 4.6 +/- .2 gm/dl) to evaluate the effect of Hgb on survival and to look for other predictors of outcome. All patients had refused blood transfusion on religious grounds and were participants in a randomized, controlled study of the blood substitute Fluosol DA-20 per cent. Patients were analyzed as a group and after stratifying by Hgb into four levels: (Hgb less than 3.0 gm/dl, N = 7; Hgb less than 3.5 gm/dl, N = 12; Hgb less than 4.0 gm/dl, N = 17; Hgb less than 4.5 gm/dl, N = 23) and by ER into two levels of less than 50 per cent and greater than 50 per cent. Only Hgb, ER, sepsis and active bleeding were predictors of outcome, with sepsis being the only significant, independent predictor of outcome at all levels (P less than .01). Active bleeding was a predictor for levels of Hgb below 4.0 gm/dl. Hgb level alone was a significant predictor only at levels below 3 gm/dl (P less than .05). Extraction ratio interacted with Hgb only below 3 gm/dl (P less than .05). Multiple independent factors influence outcome in the severely anemic patient, the strongest being sepsis and active bleeding. Prevention of sepsis and early intervention to stop bleeding should improve survival in the patient who refuses transfusion.

Ultrasonography revealed evidence of liver abscess in 126 patients who were admitted to one hospital in northeastern Thailand over a 3-year period. There were 50 cases for which a pyogenic bacterial etiology was confirmed; 34 cases (group 1) were caused by Pseudomonas pseudomallei (nine patients died) and 16 cases (group 2) were caused by other bacteria (two patients died). Melioidosis was associated with anemia and underlying diabetes or renal disease; right-upper-quadrant pain and jaundice were more common in group 2 (P less than .05). Blood cultures were positive for bacteria in 68% of group 1 and 50% of group 2. Chest radiographs revealed abnormalities in 17 of 30 group 1 patients and 6 of 12 group 2 patients. The radiographic appearances of a blood-borne pneumonia suggested melioidosis. The serum indirect hemagglutination assay for antibodies to P. pseudomallei was of limited value in differentiating the two types of abscesses. Multiple hypoechoic areas on ultrasonography were significantly associated with melioidosis (P less than .01); associated splenic abscess occurred in 19 group 1 patients but only one group 2 patient (2-107, 95% confidence interval; odds ratio, 19). In an area where P. pseudomallei is endemic, these characteristic ultrasonographic findings should prompt immediate treatment for melioidosis.

Although in the past, rates of heart disease, cancer, and diabetes were lower in Alaska Natives than in US whites, these diseases are now increasing. The rate of iron-deficiency anemia for Alaska Natives continues to be higher than that in the general population. To understand the role of diet in these chronic diseases, seasonal dietary intakes of 351 Alaska Native adults from 11 communities were assessed during 1987-1988. Alaska Natives consumed more energy (19%), protein (39%), fat (21%), carbohydrate (13%), iron (25%), vitamin A (53%), and vitamin C (31%), but less calcium (19%) than did the general US adult population [National Health and Nutrition Examination Survey II (NHANES II)]; Alaska Natives consumed six times more fish but less fruits and vegetables. Results suggest that energy and protein intakes decreased in the last 30 y but the proportion of energy from fat (37%) remained unchanged. High fish consumption and large seasonal dietary variations persisted, which may protect against chronic diseases. However, excess energy and fat and low calcium, fruit, and vegetable intakes may be contributing to recent increases in chronic diseases. Dietary guidelines are proposed.

A 29-year-old diabetic woman who developed severe anaemia, nephrotic syndrome, and hypertension before the 28th week of gestation, had residual evidence of toxaemia and renal dysfunction more than 1 month following delivery. The histopathological findings of renal biopsy specimens were considered most consistent with toxaemia of pregnancy complicated by diabetic glomerulosclerosis. We consider that rapid acceleration of renal dysfunction may have been induced by: (1) poor control of diabetes before pregnancy; (2) glomerular hyperfiltration of the remnant nephrons throughout pregnancy; (3) hypercoagulopathy associated with pregnancy; (4) appearance of hypertension following these three conditions.

Severe ballooning of the glomerular tufts was observed in a 65-year-old man who was treated with mitomycin C (MMC) and had typical MMC-induced renal lesions. He developed renal failure and severe anaemia 6 months after initiation of chemotherapy. Ballooned tufts were caused by enormous expansion of the sub-endothelial space simultaneously associated with mesangiolysis. Glomerular cysts, described in a variety of disorders including thrombotic microangiopathy and diabetes mellitus, are derived from cystically dilated and united capillary luminae secondary to mesangiolysis. The morphogenesis of this unusual lesion when induced by MMC differs from that of the glomerular cysts previously reported.
