In a randomized trial to determine whether oral vitamin E reduced stages III and IV bronchopulmonary dysplasia (BPD) by 50%, 268 infants were randomly allocated, after stratification by birth weight and severity of disease, to receive vitamin E 25 units or an indistinguishable placebo. The experimental (E) group and the control (C) group were similar in weight, gestational ages, Apgar scores, severity of illness, and initial oxygen and ventilator exposure. Serum vitamin E levels were significantly different within 48 h of administration and remained well above normal adult levels from the first week of life in the experimental group. There was no difference in the rates of early death, BPD at 28 days, or mortality from BPD. Severity was similar and no difference was seen in the incidence of necrotizing enterocolitis or sepsis. There was no evidence that vitamin E supplementation offered protection against chronic lung disease in infants less than 1,500 g birth weight.

We have discussed the relationship between systemic illness, infection, and lung disease. As we have seen, patients with a wide variety of disease states, including advanced age, diabetes mellitus, alcoholism, collagen vascular disease, cancer, heart failure, and organ transplantation are potentially at increased risk for pneumonia because of disease-related impairments in host defenses. In addition, two virtually ubiquitous conditions in hospitalized patients, malnutrition and therapeutic interventions (especially with common medications), frequently add to the risk of airway invasion by bacterial pathogens. Systemic illness not only makes lung infection more common, but may adversely affect outcome and resolution, as well as determine the clinical presentation of pneumonia. In one particular population, the intubated and mechanically ventilated patient, the risk of infection is particularly high, and nosocomial pneumonia is a major cause of mortality. To the extent that the host response itself leads to the symptoms and signs of infection, systemically ill individuals may have subtle clinical features when serious bacterial invasion is present. Many components of the host defense system can become abnormal with serious illness, but a common mechanism that ties many systemic diseases to pneumonia is an alteration in airway epithelial cell receptivity for bacteria, namely, bacterial adherence, a process that mediates airway colonization, the first pathogenetic step on the road to pneumonia. The impetus for understanding how serious illness promotes lung infection is that once these mechanisms are identified, potential preventative strategies to minimize infection risk in the individual with systemic disease may be developed. The relationship among systemic illness, the lung, and infection also exists in a different direction: infection of a systemic nature (the septic syndrome) can lead to disease in the lung (ARDS). We have described the features of the septic syndrome and identified how it may lead to lung injury, usually by indirect means, through activation of inflammatory mediators that are carried to the lung via the vasculature. Although it is frequently impossible to predict which specific patient with systemic sepsis will develop acute lung injury, the current state of knowledge does permit us to identify high-risk individuals. Surprisingly, clinical assessment rather than biochemical testing is the best predictor of the development of acute lung injury. Patients with severe injury, profound shock and multiple systemic insults are most prone to acute lung injury in the presence of systemic sepsis.(ABSTRACT TRUNCATED AT 400 WORDS)

Ureaplasma urealyticum was isolated from the lower respiratory tract of three infants with persistent pulmonary hypertension of the newborn. In one, cultures positive for U urealyticum were obtained on multiple occasions from trachea, blood, and pleural fluid prior to the infant's death on postnatal day 6. Autopsy findings confirmed the presence of severe pneumonia and the organism was again recovered from multiple sites. A second infant had no apparent predisposing factors for development of persistent pulmonary hypertension of the newborn but U urealyticum and Staphylococcus epidermidis were recovered from the trachea antemortem and from lung tissue obtained during autopsy on the 12th postnatal day. The third infant had persistent pulmonary hypertension of the newborn and a pulmonary infiltrate within hours after birth with tracheal cultures positive for both U urealyticum and Mycoplasma hominis. Erythromycin was given for ten days, and the infant gradually improved. Prolonged ventilation with supplemental oxygen was necessary, and chronic lung disease developed. This is the first report of neonatal ureaplasmal pneumonia with sepsis and persistent pulmonary hypertension of the newborn as well as the first time a microorganism other than streptococci has been specifically implicated in the pathogenesis of persistent pulmonary hypertension of the newborn. Respiratory infections with U urealyticum or other bacteria should be considered as possible causative or contributory factors in infants with persistent pulmonary hypertension of the newborn.

The 247 eventrations operated upon concerned 230 patients (60% women and 40% men) mean age 54.5 years. Eventrations were large (collar greater than 10 cm) in 18, 5% and were in the median line in 81%. Serial laparotomies by the same approach had been performed in 21%, the principal causes of eventration being biliary and gynecologic surgery. Parietal sepsis developed in 31,5% of cases after operation for the original affection. Classical favoring factors found included obesity (51%), multiparity (42% of women) and chronic lung disease (14%). Preoperative preparation involved the use of Goni Moreno's progressive pneumoperitoneum in 18,5% of patients. Procedures used were parietal repair by raphe (22%), the same but with the addition of a dacron prosthesis (6%) or the large dacron tulle prosthesis for wide reinforcement of the visceral sac (67% of cases). Early sepsis was a slightly more frequent occurrence after dacron tulle, predisposing factors being the prosthesis itself, a previous history of parietal sepsis, swabs and the number of Redon tubes. After use of dacron tulle complications were mainly also hematoma (3.2%) and skin necrosis (2,6%). Postoperative course in general was uncomplicated in 91% of the 247 operations. Follow up of 67% of operated patients for a mean of 5 1/2 years showed recurrence in 50% of raphe procedures and 18.5% of prosthesis implantations; factors of aseptic recurrence (16,5%) were multiparity and chronic lung disease. Delayed sepsis after dacron tulle use affected 8% of patients and were related to chronicity of early sepsis, nonresorbable sutures and sepsis complicating the primary laparotomy. Doming of the parietal wall was noted in 4% of cases repaired by prosthesis.(ABSTRACT TRUNCATED AT 250 WORDS)

A wide variety of noncytotoxic drugs, including antibiotics, analgesics, narcotics, and psychotrophic and cardiovascular agents, may cause lung injury accompanied by roentgenographic infiltrates. The clinical manifestations of drug-induced lung disease are protean. Patients may present with acute injury resembling the adult respiratory distress syndrome, which must initially be distinguished from bacterial sepsis. Other drug-associated lung injury is characterized by a more subacute pneumonitis similar to an atypical infectious pneumonia. Finally, some drugs may cause insidiously progressive pulmonary infiltrates that share features with granulomatous infections. The more common drug reactions are discussed in this review, and, although the features of drug-induced lung disease are often relatively nonspecific, those features that either mimic infectious causes or may be helpful in differentiating these processes from infections are given particular emphasis.

Malnutrition has a tremendous impact on respiratory functions. It affects respiratory muscle performance, lung structure, defense mechanisms, and control of ventilation and predisposes to respiratory failure and prolonged mechanical ventilation. Calling clinicians' attention to this common clinical problem is the first step toward developing a systematic approach to patient care in which correction of malnutrition is an integral part of the therapy. The increased morbidity and mortality in malnourished patients can be better understood when they are superimposed on other disease conditions, such as chronic lung disease, sepsis, trauma, and cardiovascular dysfunction. Most important is the fact that many of the consequences of malnutrition can be partially reversible with appropriate refeeding.

The impact of early prophylactic use of intravenous indomethacin on the incidence and severity of periventricular-intraventricular hemorrhage and patent ductus arteriosus in 199 oxygen-requiring premature infants (less than or equal to 1300 g birth weight) was prospectively investigated. The trial was controlled, the infants were randomized, and the investigators were unaware of the group assignments. Patients with minimal (grade I) or no periventricular-intraventricular hemorrhage determined by prestudy echoencephalography were randomized within two birth weight subgroups (500 to 899 and 900 to 1300 g) to receive either prophylactic indomethacin (n = 99) or an equal volume of saline-vehicle placebo (n = 100). The first dose (0.2 mg/kg) was given within 12 hours of delivery and two subsequent doses (0.1 mg/kg) were administered at 12 hourly intervals. Prophylactic indomethacin significantly reduced the incidence of grades II to IV periventricular-intraventricular hemorrhage. Intraventricular hemorrhage was half as common in infants given prophylactic indomethacin as in control infants (23% v 46%, P less than .002). The reduction was manifested in both birth weight subgroups. Results of this study also confirmed a lower incidence of clinically significant patent ductus arteriosus in infants who received prophylactic indomethacin in contrast to those who received placebo (11% v 42%, P less than .001). No significant differences were found between treatment and control groups in the duration of oxygen therapy, mechanical ventilation, or hospitalization or in the incidence of pneumothorax, chronic lung disease, sepsis, necrotizing enterocolitis, retinopathy of prematurity, or death. Early prophylactic indomethacin initiated within 12 hours of delivery is effective in reducing the incidence of intraventricular hemorrhage as well as clinically significant patent ductus arteriosus in very low birth weight premature infants.

To exploit possible different non-cross-resistant mechanisms of cytotoxicity, 25 patients with advanced breast cancer were given combination chemotherapy consisting of iv mitoxantrone (7 mg/m2) and doxorubicin (30 mg/m2) every 3-4 weeks. The patients had predominantly visceral disease and received a median of six (range, one to 12) cycles of therapy. There were no complete responders, but 13 patients (52%) achieved partial remission lasting a median of 8 months (range, 4-21+). Three patients (12%) had disease stabilization and nine (36%) had disease progression. Hematologic toxicity was generally mild, with median wbc count and platelet count nadirs of 1900/mm3 (range, 700-3100) and 160,000/mm3 (range, 49,000-406,000), respectively. One patient may have died from treatment-related sepsis (pneumonia), but lymphangitic lung disease was not excluded. Hair loss progressing to severe alopecia over several treatment cycles was relatively common, affecting seven of 16 evaluable patients (44%). Vomiting was mild or absent in 17 (71%) of 24 evaluable patients. Three of 15 patients in whom serial measurements of left ventricular ejection fraction were performed developed significant reductions compatible with anthracycline-induced cardiotoxicity. Two of these patients also had pericardial effusions and one developed congestive heart failure. In conclusion, mitoxantrone and doxorubicin is an active, well-tolerated drug combination for the treatment of advanced breast cancer but may have appreciable cardiotoxicity.

Patients requiring prolonged (greater than 24 hours) mechanical ventilation have various conditions that result in respiratory failure. All patients requiring prolonged mechanical ventilation were subdivided into the following six groups: uncomplicated acute lung injury; respiratory failure complicated by multisystem failure; previous lung disease; trauma; other medical causes; and routine postoperative ventilation. During a one-year period, 327 patients required prolonged mechanical ventilation; acute lung injury and chronic obstructive pulmonary disease were the predominant conditions. Sepsis was both the major predisposing factor for and complication of acute lung injury. Mortality for patients with acute lung injury was 40 percent in the uncomplicated group and 81 percent in patients with acute lung injury complicated by multisystem failure. Acute respiratory failure in association with acute renal failure had a mortality of 89 percent. Number of organ systems involved also correlated with mortality. In patients with chronic obstructive pulmonary disease and pneumonitis or retained secretions, mortality was lower (30 percent), but a significant percentage of these patients (43 percent) became ventilator-dependent. Ventilator dependence did not significantly increase mortality during the course of respiratory failure.

The effectiveness of fiberoptic bronchoscopy with the addition of bronchoalveolar lavage (BAL) was evaluated in 72 patients with the acquired immune deficiency syndrome (AIDS) and parenchymal pulmonary disease. The diagnostic yield varied for different pathogens and was 94% (45/48 cases) for Pneumocystis carinii, 67% (14/21 cases) for cytomegalovirus, and 62% (8/13 cases) for Mycobacterium avium intracellulare. Of the 11 cases of documented Kaposi's sarcoma in the lung parenchyma, none were diagnosed from bronchoscopy, although characteristic endobronchial lesions were seen in 6 cases. Overall, the yield of bronchoscopy for all pathogens was 65%. Both transbronchial biopsy and BAL had high independent yields (88 and 85%, respectively) for diagnosing P. carinii pneumonia but combining the procedures gave the best yield. Cytomegalovirus was most often diagnosed from examination and culture of the BAL. Recovery of Mycobacterium avium intracellulare was highest with culture of both washings and lavage. Neither granuloma nor organisms were seen on examination of histologic specimens. Bronchoscopy with BAL was well tolerated with few complications even in 5 patients with thrombocytopenia and 10 patients requiring mechanical ventilation. Sixteen patients (22%) had an increase in temperature after the procedure without hypotension or sepsis and 1 patient (1.5%) had a moderate pulmonary hemorrhage after transbronchial biopsy. Fiberoptic bronchoscopy with BAL is a safe procedure with a high diagnostic yield in AIDS patient with lung disease.
