Cefprozil (CFPZ, BMY-28100) is a new oral cephem antibiotic without an ester linkage. Pharmacokinetic and clinical studies using CFPZ 10% fine granules were performed in pediatric patients. 1. Pharmacokinetic investigation Peak serum concentrations of CFPZ after dose of 7.5 mg/kg and 10 mg/kg were, respectively, 3.65 +/- 0.24 micrograms/ml and 6.38 +/- 3.23 micrograms/ml at 1-2 hours. The average half-life with 7.5 mg/kg administration was 0.90 +/- 0.16 hours and that with 10 mg/kg was 1.29 +/- 0.50 hours. The urinary excretion of CFPZ was about 45% (35.3-50.0%) in 6 hours. 2. Clinical investigation Enrolled in the study were 22 patients including 4 with pharyngitis, 3 with tonsillitis, 3 with bronchitis, 5 with pneumonia, 4 with urinary tract infection, and 1 each with pertussis, purulent lymphadenitis and otitis media. Responses were excellent in 14 patients, good in 5 patients and fair in 1 patient. In the assessment of the bacteriological efficacy, 8 out of 17 strains of organism identified previous to the treatment were eradicated, 5 strains were found replaced by other bacteria and 4 strains persisted, hence the eradication rate was 76.5%. 3. No adverse reactions attributable to the drug were observed. From the above results, it has been concluded that CFPZ is a highly effective and safe agent for moderate respiratory and urinary tract infections in children.

A prospective study of the efficacy of ampicillin in combination with sulbactam, a beta-lactamase inhibitor, (A/S) in perioperative prophylaxis was performed. The study consisted of two independent parts performed at the same time. Part I included 60 patients with lobectomies and segmentectomies. Group A (A/S 1 x 3 g "single shot") was compared with group B (A/S 3 x 3 g). Superficial wound infections occurred in 3 patients of group A and in 2 patients of group B. There was no empyema. Bronchitis and pneumonia were found in 10 patients of group A and in 7 patients of group B. Part II examined 25 pneumonectomies receiving A/S 3 x 3 g for 3 days. Concentrations of ampicillin and sulbactam in serum and lung tissue were determined and showed adequate levels to cope with usual bacteria in lung surgery. There was one superficial wound infection, 2 cases of bronchitis, and 2 cases of pneumonia.

Polymerase chain reaction (PCR) using primers targeting the IS6110 repetitive sequence was employed to detect Mycobacterium tuberculosis in 228 samples from patients with tuberculosis or other pulmonary diseases and controls, and the results were compared with culture and clinical findings. None of culture negative samples from 17 healthy controls were PCR positive. Of 109 active tuberculosis patients under chemotherapy, 88 (80.7%) were PCR positive and were significantly higher than 63 (57.8%) positive by culture. Fifty-nine (93.7) of 63 culture positive and 29 (63.0%) of 46 culture negative specimens contained M. tuberculosis detectable by PCR. In 41 specimens from inactive tuberculosis patients who visited to the chest clinic because of chest problems, 16 (39.0%) also gave PCR positive results. In addition, 14 (46.7%) of 30 specimens submitted for M. tuberculosis culture from patients with pulmonary diseases were PCR positive. Presumptive diagnosis of these PCR positive patients was bronchitis, pneumonia, bronchial asthma, etc. Therefore, this study suggests that PCR is sensitive and specific in detecting M. tuberculosis in clinical specimens. However, the interpretation of the PCR results in specimens from patients with pulmonary diseases should be done cautiously in areas with a high prevalence of tuberculosis.

The association between P.E.M. and frequent and severe life threatening infections including lower respiratory tract infections have been always reported. Lack of the usual general and local signs of infection in P.E.M. makes the diagnosis difficult and sometimes only postmortem. This study evaluated the frequency of chest infections as well as the sensitivity, specificity and predictivity of different signs and symptoms of the disease in 100 children with severe P.E.M. (marasmus, kwashiorkor, and marasmic kwashiorkor). Sixty two percent of the studied children had chest infection (33% pneumonia, 29% bronchitis). Although most patients were symptomatic, yet, signs and symptoms were few and mostly non specific. Chest roentgenograms are thus mandatory in evaluating patients with P.E.M. whenever possible. The only valuable signs suggestive of chest infection in P.E.M. were tachypnea (> or = 40/min) and/or chest indrawing. Both were moderately sensitive, highly specific and predictive of the disease particularly pneumonia. Their presence thus, its indicative of the need for early institution of antibiotic therapy even before the results of chest roentgenograms. Total Leucocytic count was of little diagnostic value while contrary to the common belief that tuberculin test is usually negative in P.E.M., the use of double the usual dose of P.P.D. (i.e. 10 TU) yielded positive reaction in some of the studied patients and thus must not be omitted from the routine investigations of malnourished patients.

Because of difficulties in accurately determining an etiologic diagnosis, the ideal treatment for lower respiratory tract infections remains questionable. Suggested regimens are made on the basis of clinical and epidemiological data. However, the single most common pathogen responsible for pneumonia remains Streptococcus pneumoniae. Atypical pneumonia in younger patients is best treated with macrolides. Older patients without debility or immunodepression are best treated with amoxycillin-ampicillin, second generation cephalosporins or cotrimoxazole, on the basis of local susceptibility patterns of microorganisms. In the treatment of acute bacterial bronchitis in chronic bronchial disease, most antimicrobial agents with activity in vitro against Haemophilus influenzae and Streptococcus pneumoniae are clinically efficacious. Among new pathogens, the importance of Chlamydia pneumoniae is variable according to the studies, and Moraxella catarrhalis was considered almost exclusively responsible for purulent exacerbations of chronic bronchitis. Therapy for empiric treatment of nosocomial pneumonia must ensure coverage for aerobic Gram negative bacilli: the most frequently used includes a semisynthetic penicillin plus an aminoglycoside, but monotherapy with newer broad-spectrum antibiotics (imipenem, ceftazidime, ciprofloxacin, timentin, etc.) seems to be equivalent to combination regimens. The lung is the most common target organ for infectious complications in immunocompromised patients but the diagnostic methods employed in the traditional work-up of pneumonia are often of little or no use in this setting. By far the two most useful clues to management of pneumonia in the immunocompromised host are the underlying host defect and the radiographic pattern of the lung infiltrate.(ABSTRACT TRUNCATED AT 250 WORDS)

This is a prospective study involving 300 persons with lung cancer admitted to the "Arnaldo Vieira de Carvalho" Cancer Institute (ICAVC). The intention of the survey was to detect delay in diagnosis after the initial symptoms. THe authors tried to identify causes of this delay and its implications. Patients were asked about the day that the symptoms started, medical care and specialists sought, number of physicians seen and their diagnosis, also examinations carried out and referrals. Results showed that 78% of cases were seen firstly by general practitioners and 69.6% looked for medical assistance at least 30 days after the clinical beginning of the disease. Chest X-rays could identify only 9 cases (3%) without symptoms. The most common clinical diagnoses were: pneumonia (20%), neoplasia (19%), bronchitis/emphysema (9.3%) and tuberculosis (8%). The number of first appointments seen by the Public Health Services and Contracted Private Hospital Network was 64.1% and the second appointment was 70%. Only 24 (8%) of the patients were referred to ICAVC just after their first appointment and 64.4% after the third. The time lost between the first appointment and the diagnosis was longer than 90 days in 55.7% of cases. These people needed to see 3 to 4 doctors (as an average) to obtain a positive diagnosis. The diagnostic techniques used more frequently were bronchoscopy (59.7%) and fine needle lung biopsy (18.4%) and the delay was 20 and 10 days on average, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Altogether 155 patients with a newly detected positive reaction to HIV (a human immunodeficiency virus) were investigated in the Republic of Burundi. Chest x-ray was done in 80 of them. Pulmonary tuberculosis was diagnosed in 2 of them, pneumonia (chronic, interstitial and bronchial)--in 15. Enhancement and deformity of lung marking were detected in 45 patients (coincidence with clinical signs of acute bronchitis was found but in 5 of them). A conclusion has been made of interstitial pneumonias being typical of HIV-infected patients and of frequent enhancement of lung marking in the preclinical stage of AIDS.

Serum amylase level was determined in 129 cases (225 episodes) of chronic respiratory failure at acute exacerbation and in 59 cases (62 episodes) of pneumonia without respiratory failure as control. Cases with accompanying diseases, such as acute pancreatitis, parotiditis, ileus and renal dysfunction, which were expected to develop hyperamylasemia were excluded. The 225 episodes were divided according to the causes of acute exacerbation into 4 groups: pneumonia, bronchitis, right heart failure without infection, and others (e. g. hemoptysis). Hyperamylasemia (greater than 400 S-U) was observed in groups of pneumonia (15/40 = 35.5%) and bronchitis (12/95 = 12.6%), respectively but not in those of right heart failure without infection (0/73 = 0%) and other causes (0/17 = 0%). As a result, hyperamylasemia was found only under conditions of inflammation of lung parenchyma and bronchi with acute exacerbation of respiratory failure. On the other hand no hyperamylasemia was observed in 62 episodes of pneumonia alone without respiratory failure. It was concluded that both respiratory tract infection and acute respiratory failure are necessary factors for development of hyperamylasemia originating from lung or bronchi.

A survey by parent questionnaire and interview was carried out to determine the frequency of health problems in 204 children with Down syndrome. Seventy-two children (35.3%) had a congenital heart defect. Refraction had been performed on 196 and 68 (34.6%) of these had a refractive error. A diagnosis of 'glue ear' had been made in 112 (54.9%) and in 12 (11%) of these permanent hearing loss was present. Significant ill-health over the previous 12 months consisted of cardiac failure (two children), more than three upper respiratory tract infections (24 children), bronchitis (eight children), pneumonia (two children) and asthma (seven children). A neck X-ray had been performed in 172 (84.3%) and had demonstrated the presence of atlanto-axial instability in 12 (7%) of these. One hundred and thirty-two (64.7%) of the children had been tested for hypothyroidism in the previous 18 months and this had been found in four (3%) of these children. The implications of these and other findings are discussed in relation to parental counselling and planning of routine health checks.
