[Parapneumonic pleural effusion: an 11-year review].

INTRODUCTION: In the last few years, the incidence of parapneumonic effusions in children with community-acquired pneumonia seems to have increased. The aim of this study was to determine the clinical features and incidence of parapneumonic effusions throughout an 11-year period. MATERIAL AND METHODS: We retrospectively reviewed the medical records of patients aged < 15 years old with parapneumonic effusions from 1993 to 2003. Annual incidence rates were calculated per 100,000 children < 15 years old from Health Area 5 of Madrid and per 100 children hospitalized in the Infectious Diseases Department of our hospital. The linear association test was used to compare the incidence rates over the previous 11 years. RESULTS: There were 130 patients with parapneumonic pleural effusions. The mean age was 4.7 years. Forty-one percent received antibiotics before diagnosis. The causative organisms were identified in 42 patients (32.3%). The most effective diagnostic method was pleural-fluid culture (18/58, 31%). The most common organisms were Streptococcus pneumoniae (18), Mycoplasma pneumoniae (8), Staphylococcus aureus (4), Streptococcus pyogenes (3), Haemophilus influenzae (3) and Mycobacterium tuberculosis (2). Thirty-two percent of the patients required pleural drainage and 16% underwent video-assisted thoracoscopic surgery. Of 12 S. pneumoniae antibiograms available, 91.7% showed full susceptibility to penicillin and 75% were susceptible to erythromycin. The annual incidence of parapneumonic effusions rose from 18.1 in 1993 to 42.9 in 2003 (p < 0.001) per 100,000 children and from 0.76 in 1993 to 3.3 in 2003 (p < 0.001) per 100 children hospitalized in our unit. CONCLUSION: The incidence of parapneumonic effusions in children with community-acquired pneumonia showed a statistically significant increase between 1993 and 2003. The most common causal organism was S. pneumoniae, with a low rate of penicillin resistance.

[Peritonsillar and retropharyngeal abscesses: study of 13 years].

INTRODUCTION: Peritonsillar and retropharyngeal abscesses are the most common deep head and neck infections. We present a series of patients with these infections. MATERIAL AND METHODS: We performed a retrospective study of peritonsillar and retropharyngeal abscesses in children admitted to the Infectious Diseases Unit of our hospital between January 1991 and January 2004. Diagnosis was based mainly on clinical and laboratory findings. RESULTS: We studied 54 patients, 10 with retropharyngeal abscess and 44 with peritonsillar abscess. The mean age was 6.7 and 7.5 years respectively. There was a slight predominance of boys (1.45:1). The number of cases diagnosed increased from 1997, with a maximum (nine cases) in 2002. Twenty-nine children had received previous antibiotic therapy. The main symptoms and signs were: fever, odynophagia, cervical lymphadenitis, and asymmetric tonsillar hypertrophy. All children received intravenous antibiotic therapy. Puncture-aspiration was carried out in seven patients. Eleven children underwent tonsillectomy, two with retropharyngeal abscess and nine with peritonsillar abscess. Of these 11 patients, five had had several episodes of tonsillitis and three had previously had a peritonsillar abscess. Three children who developed an abscess had previously undergone tonsillectomy. In most patients, outcome was favorable. CONCLUSIONS: In the last few years the frequency of peritonsillar and retropharyngeal abscesses has increased in the pediatric population. Most of the children have a good response to conservative treatment. The main risk factor for abscess recurrence is a previous history of repeated tonsillitis. Consequently, these patients are candidates for tonsillectomy.

[Tuberculous meningitis: a review of 27 years].

OBJECTIVES: To analyze the features and outcome of children with tuberculous meningitis (TM) in a tertiary hospital in Madrid, with special emphasis on the possible influence of HIV infection, immigration and withdrawal of the Bacille-Calmette-Guérin (BCG) vaccine in Madrid in 1987. METHODS: We reviewed the medical records of patients with TM diagnosed over a 27-year period (1977-2003). TM was diagnosed on the basis of compatible cytochemical findings in cerebrospinal fluid (CSF), plus a) isolation of Mycobacterium tuberculosis in CSF or gastric fluid; b) positive Mantoux test, or c) previous contact with active tuberculosis. RESULTS: Twenty-eight cases of TM were diagnosed. There were 24 cases (85 %) in the first 14 years versus only four cases (15 %) in the last 13 years. None of the children was co-infected with HIV. The median age was 3 years and 4 months. Only two of these had received the BCG vaccine. The source of infection was identified in 64 %. At admission, 57 % had nuchal rigidity, 46 % had neurological focality, and 54 % had an abnormal chest roentgenogram. The Mantoux purified protein derivative (PPD) test was positive in 89 % at diagnosis. Zhiel-Nielsen smear in CSF was positive in 3.5 %, and a positive culture from CSF was obtained in 32 %. Computed tomography scan was performed in 22 children and showed hydrocephalus in 90 %. All patients were treated with four drugs, with no significant adverse events. Corticoids (89 %), ventricular-peritoneal shunt (43 %) and antiepileptic drugs (39 %) were widely used as complementary treatments. Mortality was 12 %. Half of the patients had sequels, which were mostly permanent. The most frequent and severe complication was neurodevelopmental delay (21 %). Severe sequels occurred in children with more advanced stages of illness. CONCLUSIONS: The frequency of TM has decreased in the last 15 years, despite the emergence of HIV and immigration from countries where tuberculosis is endemic. These data are in agreement with the general reduction of the incidence of TM in our environment. Withdrawal of the BCG vaccine in Madrid in 1987 did not increase cases of TM in our hospital; on the contrary, these have decreased. A considerable percentage of children with advanced stages of TM show severe sequels.

[Non-typhi Salmonella bacteremia in children: an 11-year review].

OBJECTIVES: To review the clinical and bacteriological features of pediatric patients with non-typhi Salmonella (NTS) bacteremia. METHODS: We reviewed the medical records of children aged less than 14 years with culture-proven NTS bacteremia in the previous 11 years in a referral hospital in Madrid, Spain. RESULTS: A total of 29 cases of NTS bacteremia were diagnosed. Of these, 27 were used for study purposes. The mean age was 11.1 months (range: 3 days to 11 years); 48% were infants aged < 1 year. Eleven children (41%) had an underlying disease. These included immunodeficiency in seven (malignant disease in three, IgA-IgG2 deficit in one, chronic granulomatous disease in one, HIV infection in one, and systemic lupus erythematosus in one patient on steroid treatment), liver disease in three, and hypoxic-ischemic encephalopathy in one. Clinical manifestations at the initial visit included: fever > 39 C (85%), diarrhea (67%), and vomiting (37%). Seven patients had occult bacteremia. Three children (11 %) required intensive care management for severe sepsis. Five patients presented extraintestinal focal infections: arthritis in two, osteomyelitis in one, urinary tract infection in one, and pneumonia in one. None of the children had meningitis or died as a result of NTS infection. The most common serogroups isolated were Salmonella D9, and B4-5 (38% each). Eleven strains (38%) were resistant to amoxicillin and five (17%) were resistant to cotrimoxazole. Only one patient developed persistent bacteremia. All the children made a complete recovery without further complications. CONCLUSIONS: NTS bacteremia is an uncommon entity but it should be considered in infants and immunocompromised children. Although focal complications may occur, the usual outcome with appropriate antimicrobial treatment is a full recovery.

[Incidence and clinical characteristics of Kawasaki's disease].

OBJECTIVE: The aim of this study was to analyze the incidence and clinical spectrum of Kawasaki's disease in children attended in our hospital. PATIENTS AND METHODS: Retrospective review of all children with Kawasaki's disease evaluated in the Department of Infectious Diseases of Hospital La Paz (Madrid, Spain) from January 1999 to June 2002. Information included clinical manifestations, age, sex, seasonal occurrence, treatment, development of cardiovascular abnormalities, and incidence rate. RESULTS: Forty-five patients with Kawasaki's disease were analyzed during the study period. Age ranged between 4 months and 13 years. Thirty-seven children were aged 5 years old or less and 15 children were younger than 2 years. The most common symptom was fever in 98 % of the patients. Five patients developed coronary aneurysms. Of these, four were aged less than 2 years and three were treated after the first week of onset of fever. The annual incidence rate in our health area was estimated at 15.1 cases per 100,000 children aged 5 years or less. CONCLUSIONS: The annual incidence rate for Kawasaki's disease in our area was similar to that in Europe and the United States. Coronary aneurysms were more common in children aged less than 2 years and in patients who received treatment after 1 week of the onset of fever.

[Acute mastoiditis: an increasing entity].

BACKGROUND: Mastoiditis used to be the most common complication of acute otitis media. However, once antibiotics became widely available, it was rarely reported. Recently, this complication has become more frequent. OBJECTIVES: To determine the frequency of acute mastoiditis in our center in the last few years and to analyze the clinical and bacteriologic characteristics of the patients with this diagnosis. METHODS: Retrospective analysis of all patients admitted to our hospital with a diagnosis of acute mastoiditis from 1994-2001. RESULTS: One hundred patients were diagnosed with acute mastoiditis during the study period. The mean age was 2 years and 10 months (range: 2 months-13 years) and the median age was 15 months. The mean number of episodes was 12.5 cases of acute mastoiditis per year, but 52 % of the cases occurred from 1999-2001. Culture of middle ear effusions was performed in 47 patients, revealing Streptococcus pneumoniae in 17, Haemophilus influenzae in 3, and other pathogens in 10 children. Cultures were sterile in 17 patients. Three children did not respond to medical therapy and required mastoidectomy. CONCLUSIONS: In the last few years, the incidence of acute mastoiditis in our population has increased considerably. This complication is more common in children aged less than 2 years.

[Pulmonary tuberculosis in children: its age-dependent aspects].

OBJECTIVE: The aim of this study was to investigate the clinical and radiological particularities of pulmonary tuberculosis depending on the age of the child. PATIENTS AND METHODS: The medical records of all children with pulmonary tuberculosis diagnosed between 1985 to 1996 were reviewed. They were divided into three age groups according to age: < 3 years, 3-5 year and 6-15 years. RESULTS: Of the 173 children identified, 51.4% were male. Forty percent were < 3 years if age, 33.1% between 3 and 5 years and 26.1% between 6 and 15 years old. The frequency of diagnosis derived from a case contact investigation was higher in children < 3 years of age (38.6%) and children aged 3-5 years (52.6%) than in children between 6-15 years old (21.7%, p < 0.05 for both). In the other cases, diagnosis was the result of investigation of an ill child, investigation of a child after pulmonary tuberculosis was diagnosed in a sibling and routine tuberculin skin test reactivity. An adult source of tuberculosis was identified in 68.6% of the children < 3 years old, 59.6% of children aged 3-5, but only in 37% of the children aged 6-15 years (p < 0.05 for both). The case contact was a family member in 92.7% of the children < 6 years of age and in 66.7% of children aged 6-15 years (p < 0.01). Culture of Mycobacterium tuberculosis was positive in 47.1% of children < 3 years old and 43.9% of children aged 6-15 years, but only in 27.5% of children aged 3.5 years (p < 0.05). Pulmonary parenchymal disease was more frequently found in children < 3 years (67.5%) than in children aged 6-15 years (39.4%, p < 0.05). CONCLUSIONS: Investigation of an adult source is essential when a child is diagnosed of pulmonary tuberculosis. Pulmonary tuberculosis is more intense and the source of adult contact is more frequently found in children < 3 years old.

[Bacterial meningitis in pediatrics. Study of 166 cases].

OBJECTIVE: The purpose of this study was to evaluate the clinical and epidemiological characteristics of meningitis in our environment. PATIENTS AND METHODS: A retrospective study of 166 cases of meningitis diagnosed in our hospital during a 10 year period (1986-1995) was performed. The patients were between 1 month and 14 years of age. RESULTS: Sixty-six percent of the patients were male and 34% female. Eleven cases were younger than 2 months (6.6%), 122 cases (73.5%) were between 3 months and 5 years of age and 33 cases (19.9%) were older than 5 years. The most frequent symptoms and signs were fever (96%), vomiting (60%), impairment of consciousness (24%) and meningeal signs (49%). CSF cultures were positive in 52% and blood cultures in 32%. The pathogen isolated was N. meningitidis in 53 cases (32%), H. influenzae in 38 (23%), S. pneumoniae in 9 patients (5%) and others in 3 children (2%). Meningitis due to H. influenzae increased each year. No microorganism was isolated in blood and CSF in 63 cases (38%). Meningitis in children between 3 months and 5 years of age was due to N. meningitidis in 40 children (33%) and H. influenzae in 36 (29%). The mortality rate was 3%. The most frequent complications were sepsis (36%) and seizures (16%). CONCLUSIONS: The most frequently isolated agent in our study was N. meningitis. Meningitis due to H. influenzae is increasing such that H. influenzae and N. meningitis currently show similar frequency in children between 3 months and 5 years of age.

[Whooping cough: a retrospective study of the cases diagnosed over a period of 15 years].

OBJECTIVE: Our objective was to study the whooping cough cases diagnosed in a 15-year period in our hospital, referring to its clinical features, epidemiology and analytical findings. PATIENTS AND METHODS: A retrospective study based on 144 cases with a clinical diagnosis of whooping cough, from 1981 to 1995, was carried out. Special attention was paid to those cases with cultures positive for B. pertussis. RESULTS: Nasopharyngeal specimens for culture were taken in 119 cases. This was not carried-out in those with previous antibiotic therapy. Cultures were positive for B. pertussis in 46 patients (38.7%). The age varied between 20 days and 30 months. Twenty-one were female. The initial symptoms were: paroxysmal cough in 44 (95.7%), cyanosis in 34 (73.9%), inspiratory whoop in 27 (58.7%), respiratory distress in 12 (26.1%) and post-tussive vomiting in 10 (21.7%). Thirty-nine children (84.8%) of this group had not received any pertussis vaccine, the rest had received just the first dose. It had been contacted by persons having cough in 19 patients (41.3%). Leukocytosis (mean: 19,818/mm3), lymphocytosis (mean: 13,047/mm3) and high platelet count (mean 459,522/mm3) were common findings. CONCLUSIONS: Cultures were positive in 38.7% of the patients. There are similar findings by other authors. In this group, most of the children were unvaccinated, and less than 3 months of age. Typical symptoms of pertussis were observed in the majority of patients. In one forth of them respiratory distress was found, probably related to their young age. Vaccinated adults emerge as a contact group that should be studied.
