The combined cause-of-death category pneumonia and influenza (P&I) (International Classification of Diseases, Ninth Revision, codes 480-487) ranks as the sixth leading cause of death in the United States following heart disease, cancer, stroke, unintentional injuries, and chronic obstructive pulmonary disease. Changes in the epidemiology of Streptococcus pneumoniae and other recognized respiratory pathogens, the increasing occurrence of drug-resistant microorganisms, and the detection of new respiratory pathogens have heightened awareness of the public health importance of severe respiratory infections. To characterize the epidemiology of P&I deaths in the United States, CDC further analyzed underlying and multiple cause-of-death mortality files for 1979-1994. This report summarizes the results of this analysis.

Sixty consecutive patients admitted to a teaching hospital with acute stroke were studied prospectively for 3 months to define the natural history and consequences of lung aspiration. Using videofluoroscopy, aspiration was identified in 25 patients (42%) within 72 h of stroke onset, and had resolved in all but three patients (8%) after 3 months. It was closely related to the presence of dysphagia, which itself resolved within 2 weeks in all but the persistent aspirators. Lower respiratory tract infection (LRTI) was more common in aspirating patients (68%) than non-aspirators (6%). The use of intravenous fluids without oral intake did not appear to prevent LRTI in aspirating patients who were also dysphagic. Pneumonia occurred after 2 weeks in the three patients subsequently found to aspirate persistently. Aspiration is a transient phenomenon in most cases of acute stroke; it is associated with a high incidence of LRTI, but mortality in this series was not significantly associated either with respiratory tract infection or aspiration itself.

Bacteriological, pharmacokinetic and clinical studies on SY5555 dry syrup (powder which is dissolved before use), a new penem antibiotic for oral use, were performed. The following results were obtained. 1. Antibacterial activities. MICs of SY5555, clavulanic acid/amoxicillin (CVA/AMPC), cefotiam (CTM), cefpodoxime (CPDX), cefaclor (CCL) and cefdinir (CFDN) were determined against clinically isolated Staphylococcus aureus, coagulase negative staphylococci, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli and Enterobacter cloacae at a dose of 10(6) CFU/ml. MICs of SY5555 against S. aureus, CNS, S. pneumoniae, S. pyogenes, H. influenzae, M. catarrhalis, E. coli and E. cloacae were 0.2, 0.2, 0.2, < or = 0.025, 0.78, 0.2, 0.78 and 3.13 micrograms/ml, respectively, showing excellent antibacterial effects on these pathogens. Although the effects of SY 5555 against H. influenzae and E. coli were slightly inferior to those of CPDX and CFDN, the drug showed the most excellent antibacterial effect on other strains as compared with the control drugs. 2. Absorption and excretion In this study, plasma concentrations and urinary recovery rates were examined after administration of SY5555 at doses of 5 and 10 mg/kg (potency) after meals. With both 5 and 10 mg/kg doses, peak plasma concentrations were reached 1 hour after administration, at 0.25-2.61 micrograms/ml (mean 1.47 micrograms/ml) and 1.08-2.17 micrograms/ml (mean 1.74 micrograms/ml), respectively. The plasma levels rapidly decreased to 0.06-0.19 micrograms/ml (0.12 micrograms/ml) and 0.0503-0.0637 micrograms/ml) after 6 hours. The half-lives 1.12 hours in the 5 mg/kg group and 1.0 hour in the 10 mg/kg group. The urinary recovery rates were determined in the first 8 hours after administration in the 5 mg/kg and 6 hours in the 10 mg/kg group, and the values were as low as 1.05-12.3% and 1.6-4.33%, respectively. 3. Clinical results The clinical responses were examined in a total of 73 cases including 4 acute pneumonia, 13 acute bronchitis, 11 tonsillitis, 3 pharyngitis, 12 scarlet fever, 2 pertussis, 6 urinary tract infection, 6 otitis media, 7 lymphadenitis, 2 staphylococcal scalded skin syndrome, 2 phlegmon, 4 impetigo and 1 purulent parotitis. The treatment was effective or better in 66 of 70 cases with an efficacy rate of 94.3% (3 undeterminable cases were excluded). Bacteriological effects were examined during the clinical course for detected or suspected pathogens found before administration of SY5555. The effects were determined in 50 cases including 7 cases of polymicrobacterial infections, 57 strains in total. Eight strains, however, persisted, hence the overall eradication rate was 86.0%.(ABSTRACT TRUNCATED AT 400 WORDS)

From 1981 through 1991, 40 patients 80 years of age or older underwent thoracotomy for curative resection of bronchogenic carcinoma. There were 22 males and 18 females with a mean age of 82.7 years (range 80-88). In three patients, the operation was aborted due to unexpected metastatic disease discovered at the time of thoracotomy. The remaining 37 patients underwent 5 pneumonectomies, 26 lobectomies and 6 segmentectomies or wedge resections. Three of these patients (1 pneumonectomy, 1 lobectomy, and 1 wedge resection) underwent concomitant en bloc chest wall resection. The overall operative mortality rate (in hospital or within 30 days) was 15% (6/40) while there was a 16% mortality rate (6/37) for resected patients. Complications occurred in 18 of 40 patients (45%) but were major in only 12 (30%). Major complications included respiratory insufficiency (6), pneumonia (4), prolonged air leak (2), stroke (1), urinary retention prostatectomy (1), and one unexplained sudden death 2 weeks following discharge. Postoperative stay in the 34 operative survivors averaged 14 +/- 8.8 days (range 3-47). Univariate analysis revealed that neither gender, extent of lung resection, preoperative NYHA class, history of heart disease nor chronic obstructive pulmonary disease (COPD) were predictive of operative mortality in the 37 patients undergoing lung resection. Age was the only predictor of mortality (survivors 82.2 +/- 2.2, non-survivors 84.3 +/- 2.6; P < 0.05). The need for chest wall resection approached but did not quite achieve significance (P < 0.08). Actuarial survival for all 40 patients at 1 and 3 years is 55% and 40%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of penetrating wounds to the neck remains controversial despite decades of discussion in the literature. We assessed 393 consecutive stab wounds penetrating the platysma operated at our trauma service between January 14, 1991 and September 30, 1992 to evaluate our policy of mandatory neck exploration (NE). Injury to the common (n = 19 cases), external (n = 7), internal carotid (n = 5), innominate (n = 2), subclavian (n = 20), vertebral (n = 12), facial (n = 2), and intercostal (n = 2) arteries; the external (n = 36), internal (n = 65), subclavian (n = 20), and innominate (n = 4) veins; the pharynx/esophagus (n = 21); and the trachea (n = 28) was considered a positive NE (n = 167). 226 NEs were negative. Except for hemiparesis and bruit, the presence of clinical signs (shock, active hemorrhage, hematoma, surgical emphysema, dysphagia, blowing wound) did not predict a positive NE. Clinical signs were absent in 30% of positive NEs and in 58% of negative NEs. Complications of positive NE included wound infection (n = 7 cases), chyle drainage (n = 6), cerebellar stroke (n = 1), pneumonitis (n = 8), reoperation for recurrent hemorrhage (n = 1), subclavian artery graft occlusion (n = 1), bronchopleural fistula (n = 1), and cerebrospinal fluid leak (n = 1). Negative NEs were complicated by a wound infection in four cases and pneumonitis in one case. The mean hospital stay was 4.3 days for those with a positive NE and 1.5 days for those with a negative NE.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients with epilepsy may be subject to an increased risk of premature death from the underlying cause, or from the epilepsy itself. The extent and nature of this risk has been insufficiently investigated. Standard mortality ratios (SMRs) of patients with newly diagnosed epilepsy were determined in a prospective national population-based study. 1091 patients with newly diagnosed or suspected epilepsy were ascertained who were attending one of 275 UK general practices from 1984-1987. 1091 patients were classified after 6 months as definite epilepsy (564), possible epilepsy (228), febrile seizures (220), or not epilepsy (79). Over a median follow up of 6.9 years the SMR for patients with definite or possible epilepsy was 2.5 (95% CI 2.1-2.9), and 3.0 (2.5-3.7) for definite epilepsy. The SMR was highest during the first year after diagnosis 5.1 (3.8-6.5), declined to 2.5 (1.5-3.9) at 3 years, and 1.3 (0.7-2.0) at 5 years. The commonest causes of death were pneumonia (SMR 7.2), cancer (3.5), and stroke (3.7). The SMR for patients with idiopathic epilepsy was 1.6 (1.0-2.4), remote symptomatic epilepsy 4.3 (3.3-5.5), and acute symptomatic epilepsy 2.9 (1.7-4.5). Mortality in patients with newly-diagnosed epilepsy was high, mainly due to the underlying cause. The SMR for idiopathic epilepsy was also raised, suggesting that epilepsy per se may carry a small risk of death.

Alternating chemoradiotherapy has recently been reported to produce encouraging results in patients with advanced head and neck cancer. We have treated 17 patients with squamous cell carcinoma of the upper esophagus by alternating chemoradiotherapy and by following the patients for 2 to 5 years, or until their death. Chemotherapy (cisplatin and 5-fluorouracil) was delivered during weeks 1, 4, and 7, and radiotherapy (180 to 200 cGy twice each day to 2,000 cGy) during weeks 2, 5, and 8 (total 6,000 cGy). Three patients (18%) died of toxicity (nadir sepsis). All 14 patients who survived the treatment achieved a complete response as shown by endoscopy and biopsy specimens, with restoration of swallowing, and none experienced a local relapse. Three patients died of distant metastases (actuarial incidence 32% at 3 years). The 5-year survival rate was only 16%, however, because 8 other patients with no evidence of the cancer died of a variety of other causes: radiation pneumonitis (1), chronic neutropenia (1), esophageal actinomycosis (1), pneumonia (2), stroke (1), myocardial infarction (1), and small-cell lung cancer (1). Conceivably, some further improvement in the results might occur from cytokines, stem cells, and brachytherapy (by decreasing deaths due to toxicity), but with so many causes of comorbidity it seems unlikely, for the foreseeable future, that the 5-year survival rate could be much improved by better treatment of esophageal cancer.

The objective of this study was to validate a dysphagia screening test to identify patients in the rehabilitation phase post stroke at risk for pneumonia, recurrent upper airway obstruction, and death. The setting was an inpatient stroke rehabilitation unit. One hundred thirty-nine consecutive patients met the following criteria: stroke confirmed by clinical history and neurological exam with compatible computed tomography (CT) or magnetic resonance imaging (MRI) scan; ages 20 to 90 years inclusive; and no known history of significant oral or pharyngeal anomaly. The main outcome measures were pneumonia, recurrent upper airway obstruction, and death. The Burke Dysphagia Screening Test (BDST) identified 11 of 12 patients who subsequently developed pneumonia, recurrent upper airway obstruction, or death (Fisher's exact test: p = .03). The relative risk for the occurrence of any of these complications was 7.65 times greater for those failing versus passing the BDST. The BDST identified 9 of 9 patients who developed pneumonia (Fisher's exact test: p = .01). We concluded that the BDST is of value in identifying patients in the rehabilitation phase poststroke at risk for pneumonia, recurrent upper airway obstruction, and death.

Anatomical variations in aortic root pathology, including combinations of dissection, aneurysmal dilatation, annuloaortic ectasia, and valve disease, defy standardized repair and mandate application of various surgical reconstructions. To examine these techniques, and their influence on morbidity and mortality, we reviewed 53 consecutive patients undergoing aortic root procedures. Thirty-two patients underwent total root reconstruction. Of these, 21 underwent Bentall procedures, 9 had a modification thereof, and 2 underwent a Cabrol reconstruction. Less extensive pathology was corrected in 21 patients with a partial root reconstruction. These included aortic valve replacement (AVR) and a separate tube graft in 14 patients, AVR and primary aortic repair +/- wrapping in 4 individuals, and AVR and patch aortic root enlargement in 3 patients. Mean age was 53.2 years (range 20 to 79). Nearly 20% had undergone previous cardiac surgery and 7.5% were emergencies. Early mortality was 4%. Complications included dysrhythmias (48%), myocardial infarction (4%), stroke (4%), pneumonia (14%), and pancreatitis (2%). There were no reoperations for bleeding. Three late complications, one pseudoaneurysm and two perivalvular leaks, were successfully repaired. Late deaths (13.7%) were caused by congestive heart failure (3), myocardial infarction (MI) (1), cancer (1), stroke (1), and accidental fall (1). Kaplan-Meier analysis reveals 1-, 5-, and 10-year survivals of 98%, 81%, and 66%. Survival and mortality data did not differ between groups, and except for the incidence of atrial dysrhythmias, complication rates also were not significantly different. This series illustrates the need for and the successful application of a selective approach to aortic root reconstruction.

Spinal operation via an anterior thoracic approach is becoming increasingly common, and the thoracic surgeon is now being called upon to provide exposure for orthopedic and neurosurgical colleagues. We report experience with 126 such patients from 1982 through 1993. There were 61 male and 65 female patients (mean age, 39.0 years; range, 14 to 77 years). Indications were trauma in 45 patients (36%), spinal deformity in 42 (33%), cancer in 15 (12%), disc disease in 12 (10%), and infection in 12 (10%). Operative incisions included 22 (17%) right and 14 (11%) left thoracotomies, 33 (26%) right and 56 (44%) left thoracolumbar approaches, and one (1%) sternotomy. A prior spinal operation had been performed on 31 patients (25%), and 56 (44%) had a subsequent posterior spinal operation. Instrumentation was used in 38 (30%) and bone grafts in all but 6 patients. A neurologic deficit was present in 69 patients (55%) preoperatively and was improved in 67 patients postoperatively. Operative mortality was 3.2% (4 patients) due to myocardial infarction, stroke with pneumonia, adult respiratory distress syndrome, and malignant biliary obstruction. Univariate and multivariate risk analysis were performed. Only the diagnosis of osteomyelitis proved to be a significant (p = 0.0002) indicator of operative mortality, with 3 of 12 such patients dying (25%). These results suggest that anterior spinal exposure via thoracic approach is a major operation with considerable perioperative risk. Patients with osteomyelitis appear to be at increased risk for operative mortality.
