Forty-five patients (25 male and 20 female) over 12 years of age with cystic fibrosis have been studied clinically, radiologically and physiologically. Their mean age at the first visit was 17 years; they were followed for a mean period of 4 years and attended at least every six months. The first symptom which developed before the age of five in 42 of the 45 patients was respiratory. Thirty-two of the 45 patients had severe lung disease (Group III) at the start of the study of the seven patients died during the study. Cough and sputum were almost universal, 23 had haemoptyses and eight pneumothoraces. Staphylococcus pyogenes, Haemophilus influenzae and Pseudomonas aeruginosa were the common pathogens isolated from sputum and the increasing prevalence of the latter was again confirmed. Acquisition of the mucoid strain of pseudomonas signified poor prognosis. Established infection was never eradicated. Forty-three patients had evidence of pancreatic insufficiency; in all but one patient the symptoms were mild and five patients abandoned dietary restriction and pancreatin without ill effect. Seven patients had symptoms of partial bowel obstruction (meconium ileus equivalent) but only one required surgical relief. The liver was enlarged in seven patients and the spleen was felt in three. Three patients had diabetes mellitus. The influence of cystic fibrosis on growth and development is reported--the growth spurt is late in the majority but growth failure is not confined to those with severe lung infection or malabsorption and in these circumstances remains unexplained. Mean weight was low in relation to height and puberty was delayed in both sexes.

Mucormycosis classically occurs in patients who have uncontrolled diabetes who develop rhinocerebral disease. A fatal case of rhinocerebral infection caused by Rhizopus arrhizus in a 53-year-old man who had received a renal homograft three years previously is reported. Only five similar cases have been documented, all since 1970. Although direct smears of the purulent nasal exudate revealed the presence of numerous Gram-negative bacilli, later identified as Haemophilus influenzae, the diagnosis of mucormycosis was made by demonstrating the typical broad, nonseptate branched hyphae in the necrotic tissue obtained by surgical debridement of the paranasal sinuses. Culture of this material revealed growth of mold-like fungus which, upon direct microscopic examination, showed sporangiophores bearing spherical sporangia arising directly from a cluster of root-like structures of rhizoids. Despite the immediate institution of therapy with amphotericin B postoperatively, the patient died 48 hours later. Subsequently, the Rhizopus isolated was shown to be resistant to both amphotericin B and 5-fluorocytosine. The present case and two others stress the importance of an aggressive diagnostic approach to patients suspected of having mucormycosis, because the usual microbiologic technics are frequently, inexplicably, unsuccessful, and possibly even misleading in this disease.

Choosing appropriate antimicrobial therapy for patients with pneumonia requires knowledge of the etiologic agents seen in specific kinds of patients at specific times and places. For community-acquired pneumonia, there is an important difference in the agents seen in the normal and the compromised host. The normal host most often presents with viral, mycoplasmal, or pneumococcal pneumonia. The exact place of Chlamydia pneumoniae is still under study. A normal host who aspirates is at risk of anaerobic pneumonia. Normal hosts with influenza may acquire superinfection with Streptococcus pneumoniae, Haemophilus influenzae, or Staphylococcus aureus. Under specific epidemiologic conditions, community-acquired pneumonia may be due to Legionella species, Yersinia pestis, Francisella tularensis, Coxiella burnetii, Chlamydia psittaci, a mycotic agent, or tuberculosis. Patients with chronic bronchitis and emphysema are predisposed to H. influenzae, Moraxella catarrhalis, and S. pneumoniae infections. HIV-infected patients are likely to have Pneumocystis carinii pneumonia and pneumonia due to cytomegalovirus, S. pneumoniae, and H. influenzae. Patients with diabetes, nursing-home patients, hospitalized patients, immuno-compromised patients, and patients with recent antibiotic therapy are predisposed to pneumonia due to Gram-negative aerobic bacilli of enteric and environmental origin. Initial therapy should be directed at the likely organism or organisms based on hospital susceptibility surveillance. In the normal host with community-acquired pneumonia, the therapy will often be penicillin G or erythromycin. In the patient predisposed to Gram-negative pneumonia, a third-generation cephalosporin with or without an aminoglycoside is the usual choice.

Seven juvenile periodontally diseased patients were evaluated for clinical, microbiologic and local or systemic host factors. Three patients showed the localized from of periodontitis clinically and radiographically and by deep periodontal pockets associated with the molars and incisors. Four were in the generalized froms, in which in most cases all teeth were affected. The results in both diseased froms on the predominant cultivable subgingival microflora, the composition of which was not different from that in adult periodontitis, consisted of significantly increased proportions of Gram-negative anaerobic rods, Bacteroides sp. and B. gingivalis, Haemophilus sp. and H. actinomycetemcomitans were detected in 1/3 of the localized and 2/4 of the generalized periodontitis. They were of no value in distinguishing activity that enhanced disease in the generalized from. Elevated serum IgG responses were noted with B. gingivalis. No markedly functional abnormalities of neutrophils from peripheral blood have been demonstrated, however it might function with systemic factors, like an insulin-dependent diabetes. Morphologic characteristics of the oral and periodontal tissue in localized periodontitis were that the pattern of destruction was confined to specific teeth groups characterized by extensive the bucco-lingual width ratio of the dental crown to alveolar bone width. These observations indicate that the generalized form of juvenile periodontitis lesions were associated not only with the presence of subgingival bacteria, but also with conditions such as local morphologic and systemic or constitutional factors, individual variation in relation to destructive and protective aspects of the defense mechanisms.

The subgingival microflora and serum antibody response was examined in periodontitis patients with noninsulin-dependent diabetes mellitus (NIDDM), impaired glucose tolerance (IGT), and normal glucose tolerance (NGT). The predominant cultivable microflora was determined for subgingival plaque sampled from two deep periodontal pockets in each of eight adult periodontitis patients with NIDDM. Indirect immunofluorescence for Bacteroides intermedius, Bacteroides gingivalis, and Haemophilus actinomycetemcomitans was used to examine these same samples as well as 186 additional subgingival plaque samples from 47 patients with moderate to severe generalized periodontitis including 25 subjects with NIDDM, six subjects with IGT, and 16 subjects with NGT. Serum antibody levels to 13 microorganisms including seven oral bacterial species and one nonoral control species were measured by enzyme-linked immunosorbent assays (ELISA) in 377 subjects including 84 normal subjects without periodontal disease, 112 normal subjects with periodontitis, 19 periodontally normal subjects with IGT, 65 periodontitis patients with IGT, 15 periodontally normal subjects with NIDDM, and 82 periodontitis patients with NIDDM. Three hundred eighty-two bacterial isolates were recovered from the eight patients. B. intermedius was the most frequently isolated microorganism constituting 16% of the total isolates followed by Wolinella recta and B. gingivalis, which each accounted for 13% of the total. Streptococcus sanguis was the most prevalent microorganism, which was found in 75% of the sites. Subgingival plaque samples examined by immunofluorescence demonstrate a high prevalence of black-pigmented Bacteroides and suggest that the proportion of B. gingivalis but not B. intermedius is higher in NIDDM with periodontitis than in other groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Pyarthrosis of the knee was treated in 30 patients by arthroscopic decompression and lavage, coupled with parenteral and oral antibiotics. There were 21 men and nine women patients whose ages ranged from 6 months to 65 years of age. Twenty-two patients were considered to have a hematogenous origin as a cause of their pyarthrosis, and eight were caused by penetrating trauma. Twenty-eight of these patients had the onset of symptoms within 72 h prior to arthroscopy. Two adults had the onset of their symptoms 1 week prior to treatment. Follow-up has ranged from 6 months to 5 years. Staphylococcus aureus was cultured in 20 knees, Streptococcus pneumonia in three knees, Haemophilus influenzae in four knees, and Neisseria gonorrhoeae in one knee. The average hospital stay among 22 children aged 12 years or younger was 3.50 days. The other eight patients had an average hospital stay of 9.50 days. Three adults with diabetes and other medical problems, such as renal failure, had an average hospital stay of 17.33 days. Excellent results were obtained in 28 (93.3%) of 30 patients and good results were obtained in two (6.7%) of 30 patients. There were no poor results or recurrences, and no cases of osteomyelitis occurred. This method of treatment markedly reduces the morbidity and hospital stay of patients with a septic knee.

The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

A total of 222 cases of septicaemia was recorded at the University Hospital of the West Indies between June 1982 and June 1983. This gave an overall incidence of 16.1 per 1000 admissions. The 233 bacterial strains isolated comprised 100 Gram-positive and 133 Gram-negative organisms with Klebsiella pneumoniae, Streptococcus pneumoniae and Staphylococcus aureus being the most frequent. Highest rates of septicaemia were recorded in patients less than 1 year and over 50 years of age. Septicaemia caused by Gram-positive organisms was predominantly a disease of children whereas that caused by Gram-negative organisms arose more often in neonates and in patients over 50 years of age. A predisposing factor was noted in 104 patients of whom 42 had neoplastic disease. The most frequently identified initial sites of infection were the respiratory tract, the gastro-intestinal tract and the meninges. Most blood stream infections were community-acquired, three quarters of all septicaemic patients being admitted to the departments of medicine or paediatrics. There were 11 cases of polymicrobial septicaemia caused predominantly by Gram-negative organisms in patients with underlying disease. Appropriate antimicrobial drugs were administered to 57% of septicaemic patients whereas 17% received superfluous antimicrobial therapy. In those patients who received inappropriate antimicrobial therapy there was a marked increase in mortality. Forty of 61 deaths were attributed to septicaemia. Mortality from septicaemia caused by Gram-negative organisms was 21% compared with 13% for that caused by Gram-positive organisms. The organisms associated with the highest case fatality rates were Escherichia coli, 53%; Enterobacter sp., 27%; and beta-haemolytic streptococci 24%. There were no deaths from septicaemia caused by Haemophilus influenzae, Salmonella sp. or Serratia sp. The highest mortality rates were associated with neoplastic disease, diabetes, polymicrobial septicaemia, urinary tract infections and old age.

A guest faculty discussed the management of patients with vaginal infections. It was agreed that correct diagnosis is necessary before therapy. Diagnosis can be accomplished by a microscopic examination in 90% of the cases. The cytologic smear is also very important. Specific culture media may be useful for troublesome cases, for instance, blood agar fo Haemophilus vaginalis, Trichocel medium for Trichiomonas vaginalis, Neckerson's medium for candidal species and Thayer-Martin for Neisseria gonorrhoeae. Patient history is important since some infections tend to occur in certain patients such as candidiasis in patients with diabetes mellitus, patients who are pregnant or are taking broad spectrum antibiotics, estrogen or contraceptive pills. The pH of vaginal secretions may also be helpful in making the diagnosis. It was suggested that the term "nonspecific" vaginitis is a misnomer and is used to conceal ignorance. Others felt that such agents as soap, vaginal deodorant spray, and clothing may be causatives. The term "psychogenic leukorrhea" was discussed with varying conclusions. Routine treatment for each form of vaginitis was outlines and treatment for recurrent, persistent trichomoniasis and moniliasis was given. It was agreed that douching will not cure vaginitis but may be useful in removing excessive secretion. It is not recommended for routine hygeine but is acceptable following menstruation or intercourse.

A 60-year-old man, who had non-insulin-dependent diabetes but was otherwise in good health, was hospitalized for sudden upper airway obstruction and respiratory arrest. Findings on fiberoptic laryngoscopy were consistent with acute epiglottitis. Blood cultures and factor analysis later revealed that the responsible pathogen was Hemophilus parainfluenzae. Acute epiglottitis in the adult is no longer considered rare and is usually attributed to H influenzae. The case described here and two other cases reported elsewhere indicate that H parainfluenzae may also be a cause of this serious and often fatal infection of the upper respiratory tract.
