We report the occurrence of the adult respiratory distress syndrome (ARDS) in association with uncontrolled diabetes in nine patients. In reviewing the literature we found nine similar cases reported in little over a decade. In most cases no condition known to precipitate ARDS was discovered. The evidence suggests that the severely uncontrolled diabetic state in some way may initiate pathologic events leading to the capillary leak of ARDS. This description of the association of these two entities not commonly recognized as occurring simultaneously has important clinical implications: the entity should be anticipated in uncontrolled diabetic patients who present with acidosis, hypotension, hypothermia, and/or coma. The clinical or radiologic diagnosis of pneumonia or fluid overload should not be made in the uncontrolled diabetic patient in the absence of unequivocal evidence of infection or congestive heart failure. The development of dyspnea, hypoxemia, rales, or infiltrates in the otherwise routine resuscitation of these patients should lead the clinician to suspect the development of ARDS. Prompt invasive monitoring in these cases is indicated to aid in their management and may help to improve survival. We found calculation of the A-a gradient to be useful in patients with uncontrolled diabetes. Although not necessarily predictive, widened gradients were the earliest detectable abnormality found in all patients who developed ARDS.

In this report 21 patients in whom tuberculosis was the primary cause of death, but which was not diagnosed until necropsy, are reviewed. Of the 21 deaths, 11 were due to pulmonary tuberculosis and 10 to miliary tuberculosis. Proper evaluation of the following factors might have led to the correct diagnosis in many of the patients: A family history of tuberculosis, prior pleurisy, a gastrectomy, diabetes mellitus or end-stage renal failure; all can be associated with an increased incidence of tuberculosis. A negative tuberculin skin reaction does not exclude the presence of active tuberculosis. In the search for Mycobacterium tuberculosis, the examination of just one or two sputum specimens is not an adequate bacteriologic investigation. A positive gastric smear can have diagnostic importance. Ascitic fluid findings can be characteristic of tuberculous peritonitis. A negative bone marrow aspirate for acid-fast bacilli does not exclude miliary tuberculosis. Significant anemia, high fever and leukopenia increases the possibility of tuberculosis. The persistence and/or progression of lung infiltration, irrespective of supposedly specific antibiotic therapy, strongly suggests tuberculosis. Miliary tuberculosis can present as an adult respiratory distress syndrome. All but one patient in this series had fever. the failure to diminish the pyrexia believed due to specific lung infections with presumably effective antibiotics, and the inability of therapy to control other conditions thought to cause the fever indicate the presence of tuberculosis. Tuberculosis, especially miliary disease, should be considered as a possible etiology of fever of unknown origin. If the diagnosis of tuberculosis is highly suggestive, even without bacteriologic confirmation, a therapeutic trial of antituberculosis drugs should be given.

We reviewed our experience with bacteremic pneumococcal pneumonia (BPP) over a 1-year period at a 600-bed community teaching hospital; 26 cases were identified. The mean age was 57.5 years and there were 12 male and 14 female subjects. Cough, sputum production, fever, and mental status changes were the most frequent symptoms. Risk factors included drug abuse in 10, HIV in 4, current smoking in 7, diabetes in 3, and cancer in 3. The mean PaO2/FIo2 ratio was 274. Radiographic features included a consolidation pattern in 7, bronchopneumonia in 15, combined in 1, and an initial normal film in 3. Average length of stay (LOS) was 11 days with an overall mortality of 11.5%. Four patients required mechanical ventilation, two meeting the criteria for ARDS (if this group were eliminated, LOS would be 8.4 days). Three of these survived. Four patients had organisms resistant to penicillin and all survived. We conclude that (1) BPP remains a serious but treatable infection particularly when utilizing full supportive care; (2) the bronchopneumonia x-ray film pattern was associated with all the mortality; and (3) the occurrence of penicillin resistance did not contribute to the mortality, since early recognition and the use of appropriate antibiotics saved all of these patients.

During hospitalization for severe acute necrotizing pancreatitis, a connection between the onset of retinopathy of pancreatitis and multiple-organ failure was studied. Ophthalmoscopy was repeated every second day and continuous staging for multiple-organ failure was performed in 38 patients. Typical retinopathy of pancreatitis developed in 7 of 10 patients with multiple-organ failure and only in 4 of the 28 patients without multiple-organ failure. Retinopathy of pancreatitis was observed in 7 of the 18 cases leading to lethal outcome and only in 4 of the 20 surviving patients. No correlation was observed between the development of retinopathy of pancreatitis and hemodialysis, pre-existing diabetes mellitus, abnormal platelet count, result of hemoculture, c reactive protein value, fraction of inspired oxygen and adult respiratory distress syndrome. In the 21 control patients in grave general state but without acute pancreatitis, retinopathy of pancreatitis was never observed. In our prospective study the onset of retinopathy of pancreatitis had clinical prognostic value and indicated multiple-organ failure and poor prognosis in severe acute necrotizing pancreatitis.

We have reviewed 70 consecutive elderly patients (70 years or older) who underwent pneumonectomy for bronchogenic carcinoma, in order to evaluate morbidity, mortality, and long-term survival. The majority of the patients had stage II (n = 32) or III (n = 25) disease. Fifteen deaths occurred in the peri-operative period (21%). Pre-operative factors associated with peri-operative death included a history of ischaemic heart disease (P = 0.001) and right-sided tumour (peri-operative mortality for right pneumonectomy = 37%, left pneumonectomy = 6%, P = 0.001). Poor lung function (as assessed by pre-operative spirometry), peripheral vascular disease, cerebrovascular disease, diabetes mellitus, and hypertension were not significant risk factors for peri-operative death. Post-operatively, the requirement for ventilation, or the development of post-operative myocardial infarction, adult respiratory distress syndrome and respiratory failure were significantly associated with peri-operative death. Over 60% of the patients developed one or more complications. The absolute survival rates for operative survivors were 51% and 27% at 1 and 5 years, respectively (stage I, 60% and 40%; stage II, 63% and 33%; stage III 33% and 14%). The absolute overall survival rates were 40% and 21% at 1 and 5 years, respectively. We conclude that pneumonectomy is justified in elderly patients but right-sided lesions and ischaemic heart disease should be considered as relative contra-indications.

Thrombomodulin is an endothelial cell surface glycoprotein that forms a 1:1 complex with thrombin. In this form, thrombin can activate approximately 1,000-fold more protein C than thrombin alone and does not activate coagulation factors, V and VIII, and platelets. Activated protein C inactivates factors Va and VIIIa. Thus thrombomodulin converts thrombin from a procoagulant protease to an anticoagulant. The soluble thrombomodulin present in human urine and plasma appears to represent a truncated form that lacks the transmembrane and cytoplasmic domains of tissue thrombomodulin. The plasma level of thrombomodulin has been used as a marker for endothelial injury in vivo. Elevated levels of soluble thrombomodulin were reported in the plasma from the patients with disseminated intravascular coagulation, adult respiratory distress syndrome (ARDS), and diabetes mellitus retinopathy.

To separate the effects of diabetes and inheritance on morphometric characteristics of the lung and on the variables of the pressure-volume relationship, the lungs of KK mice--a genetic model of adult-onset diabetes--were compared with the lungs of normal C57 black mice and of F1 hybrids by multivariate analysis. Hybrid mouse lungs contain more air per gram of lung tissue at total lung capacity (TLC) than the lungs of other mice (p < 0.0002) and have a lower recoil pressure at 30% to 70% of TLC. Morphometric data revealed that both the mean linear intercept and the number of alveoli per unit volume in hybrid mice fell between those in KK and C57 mice. However, the total number of alveoli per lung in hybrid mice was 155% of that in KK mice and 148% of that in C57 mice, reflecting the larger lung volume of hybrid mice. The alveolar wall thickness of the hybrids was similar to that of C57 mice, whereas KK mice had thicker alveolar walls than the other two groups. Multivariate analysis revealed that body weight, wet lung weight, volume density of blood vessels, mean linear intercept, and transpulmonary pressure at 90% TLC were affected by diabetes alone; however, the following parameters were affected by both inheritance and diabetes: lung volume, specific lung volume, femur length, volume density of alveolar air, surface area, surface to volume ratio, number of alveoli per lung, lung air per gram of lung tissue, and transpulmonary pressure at 20% to 80% TLC.(ABSTRACT TRUNCATED AT 250 WORDS)

Candidemia in critically ill patients is a significant source of mortality. To identify perioperative risk factors accounting for patient death, we performed a retrospective study of 46 surgical patients with fungemia during the period from 1981 to 1990. Twenty patients survived (43%), and 26 died (57%). Mortality was associated with age older than 46 (p < 0.02, unpaired Student's t-test) and concomitant renal failure, hepatic failure, postoperative shock, or adult respiratory distress syndrome (p < 0.0001, p < 0.0001, and p < 0.05, respectively, chi 2 test). Survival was not influenced by the presence of diabetes, chronic obstructive pulmonary disease, gastrointestinal hemorrhage, pneumonia, alcohol consumption, steroid use, or enteral/parental nutrition. Bacterial speticemia developed in 26 patients (11 lived, 15 died) and typically preceded or was concomitant with the onset of fungal sepsis (88%). Candida albicans was the fungal species most commonly isolated from blood cultures (30 of 46). Its was cultured from other sites in addition to blood in 30 patients. Candidemia carries a higher risk of mortality in older patients and in those with multiple organ dysfunction. Other immunocompromised conditions such as diabetes and steroid use did not increase mortality. These findings suggest that the pathogenicity of Candida sepsis is not solely related to opportunistic superinfections but may reflect failure of other host defense mechanisms. Moreover, the frequent occurrence of bacterial septicemia prior to the development of Candida sepsis further emphasizes the importance of fungal surveillance cultures to detect early fungal colonization in the critically ill.

A decade ago, we initiated studies to define relationship(s) between products of 5-lipoxygenase-mediated arachidonic acid metabolism and altered microvascular permeability. Patients with permeability (nonhydrostatic) pulmonary edema (adult respiratory distress syndrome) and intact animal models of permeability edema, produced with agents that required neutrophils (phorbol myristate acetate) and those that did not (ethchlorvynol), invariably revealed the presence of leukotrienes; in contrast, leukotrienes were not detected in cases of hydrostatic pulmonary edema. In isolated perfused canine lung, we identified increases in microvascular permeability coefficients in response to the injurious agent. Permeability coefficients were not increased when injurious agents were given in the presence of 5-lipoxygenase inhibitors. To define further the relationships between leukotriene generation and edema formation, we postulated that leukotrienes effected contraction of capillary pericytes, thereby increasing pore size of endothelial intercellular junctions and enhancing movement across the microvascular barrier. We isolated pericytes from bovine retinas, identified them morphologically and by staining characteristics, and, in preliminary experiments, found that they do not possess the 5-lipoxygenase enzyme; however, when cocultured with neutrophils, which possess 5-lipoxygenase but cannot synthesize sulfidopeptide leukotrienes because of their lack of glutathione S-transferase, sulfidopeptide leukotriene synthesis ensued. In view of the anatomic position of pericytes, evidence that they participate in endothelial transport, their ability to contract, and evidence of cell-to-cell communication, we propose that pericytes control the movement of fluid, solutes, hormones, and small and large molecules across the microvascular endothelium.

We studied 15 resected cases with a history of apoplexy (2.5%) among 599 cases of esophageal cancer admitted between 1972 and 1993. Fourteen were male, and female, aged 48 to 77 years. Twelve had suffered from cerebral infarction, 2 intracerebral hemorrhage, and one subarachnoid hemorrhage. Duration from apoplexy to operation was between 2 months and 19 years in the cerebral infarction cases, between 8 and 10 years in the intracerebral hemorrhage cases and 4 years in the subarachnoid hemorrhage case. Preoperative neurological disturbance was found in 7 of the 12 cerebral infarction cases, and in both intracerebral hemorrhage cases. Four cases showed hemiplegia, and the other 5 cases showed partial paralysis of limbs. Preoperative complications were found in 7 of the 15 cases, and consisted of diabetes mellitus in 5, hypertension in 4, bronchial asthma in one, and renal dysfunction in one case. Intra- and postoperative complications were found in 11 of the 15 cases, and consisted of anastomotic leakage in 5, delirium in 3, apoplexy in 2, peritonitis in one, ARDS in one, intraoperative cardiac arrest in one, and wound infection in one. Postoperative disorders of consciousness were found in 5 cases, consisting of delirium in 3, and excitation at awakening of anethesia in 2 cases. Rate of direct operative death was 6.7% in preoperative apoplectic patients, and 8.5% in non-apoplectic patients, and there was no significant difference between the 2 groups. On the other hand, rate of postoperative apoplexy was 13.3% in the preoperative apoplectic patients, and 0.4% in non-apoplectic patients. There was a significant difference between them (p < 0.01). But they were cured of it, and left our hospital. It is concluded that active surgical treatment can be indicated for esophageal cancer patients with a history of apoplexy, if more attention is given to the management of diabetes mellitus or hypertension.
