Thirteen patients with Haemophilus influenzae type b pneumonia are reported to emphasise the clinical, radiographic, and therapeutic aspects of this illness. All but one patient was under 2 1/2 years of age. The presenting complaint was a variable duration of upper respiratory infection and fever in most cases. One-third of patients had radiographic evidence of pleural involvement; one-third showed a patchy bronchopneumonia on roentgenogram; and the remainder had segmental or lobar infiltrates. Clinical response to antibiotic therapy was prompt in patients without pleural involvement.

An outbreak of illness due to Mycoplasma pneumoniae occurred among employees of a large hospital. The spectrum of disease ranged from severe upper respiratory infection to multilobed pneumonia. No unusual increase in the incidence of respiratory illness due to this organism was observed in the surrounding community during the period under investigation. It was not possible to identify any single area of the hospital frequented by enough of the involved personnel to explain the spread of the infection among the hospital's employees. This is the first outbreak of M pneumoniae disease to be reported among hospital personnel.

A variety of 40 cases of non-vegetable foreign bodies inhaled by children are presented. These include: coins, washers, pins, reamers, nails, screws, wires, pencil caps, ball-point tip, worry beads, bones, broken tooth, small stones, and blades of broken foreign body forceps. The ages of the children ranged between 10 months and 8 years with average at 2 years and 9 months. Two methods are described for the removal of slippery beads, using a Fogarty Catheter and foreign body forceps technique. Emphasis is placed on the importance of bronchoscopy in all cases with definite or doubtful history of foreign body inhalation in spite of negative physical or roentgenological findings, particularly those cases diagnosed as upper respiratory infection, pneumonitis, bronchial asthma and whooping cough, and when there is no significant response to such treatment. Fluoroscopy with image intensifier is suggested for the localization of the pointed end of sharp pins which cannot be identified clearly through the bronchoscope. General anaesthesia was used in all the cases to ensure absolute immobility. Repeated bronchoscopies at close intervals were not advised and tracheostomy was suggested in subglottic oedema if asphyxia is threatening the life of the child. Immediate removal of foreign bodies is important so as to avoid unnecessary complications. Lobectomy was necessary in one case with an impacted screw and destroyed lobe. This stresses the importance of thoracotomy when several attempts fail to remove the foreign body.

Stevens-Johnson syndrome is a symptom complex characterized by mucosal, ocular, and cutaneous lesions. Prodromal symptoms of upper respiratory infection or pharyngitis are most common. These are followed by target lesions of skin, sloughing of musous membranes, and ocular inflammation. Twenty-three cases are presented. Most patients (61 percent) were between 10 and 39 years of age. Relapses occurred in three patients. Five patients developed pneumonia, and there were two fatalities. Over one-half of the patients had serious ocular complications. The etiology of this syndrome is uncertain. Multiple allergic factors, drugs (especially long-acting sulfonamides), and infectious agents (most recently mycoplasma pneumoniae) have been implicated. This study does not support any single cause. The use of systemic steroids is generally accepted by most authors. The death rate in this study (10 percent) is essentially unchanged from early reports on patients without steroid therapy. The complications rate directly attributable to steroids is significant in this study group. The major complications of this syndrome are ocular. Aggressive topical management of ocular inflammation is required; however, the morbidity rate remains high despite these measures. The otolaryngologist should be aware of this syndrome as the early symptoms, and the acute complications may require his awareness of the natural and treated courses of this disease.

An outbreak of Mycoplasma pneumoniae (MP) infection occurred during the period March-May 1989 among the personnel of the Accident and Emergency Department of the Kuopio University Hospital, Kuopio, Finland. The index patient was a young male orderly, who fell ill with severe pneumonia. His tracheal mucus sample proved to be strongly positive for MP when tested by a commercial DNA-RNA hybridization test (Gen-Probe). After the index patient two additional staff members (an orderly and a nurse) fell ill with pneumonia and 66 others showed symptoms of upper respiratory infection or fever. The most frequent symptoms were a sore throat, a cough, rhinitis and headaches. All 97 employees of the department were tested for the presence of MP in April-May 1989 using throat swabs as test material. Forty-three (44%) were found to be positive for MP by the 'Gen-Probe' test. Eight (19%) of the MP positive staff were completely asymptomatic. The MP positive staff were retested about 3 weeks later, whereupon 40 (93%) had become negative. Most of the persons involved in this outbreak suffered only from mild respiratory symptoms, suggesting that MP outbreaks like the present one may easily pass unnoticed.

A retrospective and descriptive study was done in a general pediatric training site with the purpose of identifying the diagnoses to which the trainees have been exposed, as well as the changes in the pattern of these diagnoses. The number of patient-doctor contacts, type of patient visit, and frequency of diagnoses were compared. A total of 66,054 patient-doctor contacts occurred during the years 1979 to 1989, comprising 79.6 percent scheduled health visits and 20.4 percent emergency visits. The main diagnoses were: healthy child/adolescent (HV), well baby (WB), upper respiratory infection, skin diseases, bronchial asthma, acute gastroenteritis, otitis media, anemia, incomplete immunization, psychosocial problems, nutritional/linear growth problems, psychosomatic disturbances, parasitosis, and pneumonia. There was a significant decrease (P < .005) in the diagnosis of infectious diseases and a significant increase (P < .005) in the proportion of WB and HV. The latter were the two most common diagnoses in the year 1989.

An outbreak of respiratory syncytial virus (RSV) infection occurred among 31 patients in a marrow transplant center over a 13-week period beginning in January 1990. RSV infection was also documented in 35 family members and employees. Of 18 patients with pneumonia, 14 (78%) died. None of 13 with upper respiratory infection died. Preengraftment patients tended to develop pneumonia more frequently than did engrafted patients. Early administration of ribavirin may have had a beneficial effect in patients with pneumonia. Antigenic and genomic analysis of 14 available isolates suggested that at least four different viral strains were responsible for the outbreak. One group of patients and 1 employee in spatial proximity were infected with the same strain and likely acquired their infections nosocomially. RSV infection in marrow transplant patients is a serious and life-threatening infection with a high mortality rate once pneumonia develops.

The clinical efficacy and the pharmacokinetics of cefpirome (CPR, HR 810), a new semisynthetic cephalosporin derivative, were investigated in children with various infectious diseases. CPR showed high blood peak levels, relatively long half-life and high levels in urine. Excellent clinical efficacy was obtained in 2/3 cases with pneumonia, 3/4 cases with upper respiratory infection, 2/2 cases with cutaneous and soft tissue infection and 1/1 case with urinary tract infection. The overall efficacy rate was 80%. No clinical adverse effects were observed while slightly elevated GPT and GOT, decreased platelet were detected in 4 cases without clinical problems. CPR should be an useful and safe drug in treating infectious diseases in children.

Why does influenza virus variously eventuate in mild upper respiratory tract infection, bacterial pneumonia, or rapidly fatal viral pneumonia? The depth of infection is important. So is competence of immunologic effectors--local antibody (secretory IgA) for preventing URI, systemic antibody for preventing pneumonia, and cellular immunity for recovery from either.

The bacteriology of the isolates from the throat swab and the sputum respectively of 2,539 patients with respiratory infections visiting 21 private clinics in Tohoku district of Japan during the period from January to April in 1989 was documented. Of the 2,539 patients, 1,694 had an acute upper respiratory infection, 609 had acute bronchitis, 46 had acute pneumonia, 84 had acute exacerbation of chronic respiratory infections and 106 had respiratory infections without diagnosis registered. 1887 (74.3%) strains of potential pathogens were recovered from 1507 (59.4%) of the 2539 cases. The rate of recovery of potential pathogens was very high in patients of the younger age. These patients had elevated body-temperature. There were statistically significant differences in recovery rate when classified by diagnosis, prefecture and the period of investigation. Of the 1,887 strains, 996 (52.8%) were gram-positive and 891 (47.2%) were gram-negative bacteria. The rate of recovery of gram-negative bacteria was high in patients who were less than 10 years old and more than 51 years old, in patients with pneumonia and chronic respiratory infections, and in patients with fever. Of the 1,887 strains, those which exceeded 100 were Staphylococcus aureus (481 strains), Haemophilus influenzae (340 strains), Streptococcus pneumoniae (329 strains), Streptococcus pyogenes (117 strains) and Acinetobacter spp. (100 strains). Species other than those mentioned above had less than 100 strains. In this group there were 39 strains of Branhamella catarrhalis, 32 strains of Escherichia coli, 97 strains of Klebsiella spp., 40 strains of Enterobacter spp., 25 strains of Serratia spp., 12 strains of Pseudomonas aeruginosa and 43 strains of Pseudomonas putida. There was a remarkable difference in recovery rate of each species when classified by diagnosis, age class, prefecture and the period of investigation, respectively. The above results indicated that gram-positive bacteria are more frequent than gram-negative bacteria, that enterobacteriaceae and glucose-non-fermentative gram-negative bacteria are only rarely found in primary care clinics, and that the bacteriology in primary care clinic is different from that of medical school-affiliated hospitals.
