[Antibiotic susceptibility of Streptococcus pneumoniae in healthy carrier children in Murcia (Spain)]. / Sensibilidad de Streptococcus pneumoniae en niños portadores sanos en Murcia (España).

INTRODUCTION AND OBJECTIVES: Streptococcus pneumoniae (SP) is a human pathogen that involves a high use of antibiotics. The objective of the study was to determine the susceptibility to commonly used antibiotics and their associated risk factors, in order to promote rational use of antibiotics. PATIENTS AND METHODS: In A multicentre study was conducted in summer 2009 and winter 2010 on children attending paediatric clinics in the Region of Murcia. A nasopharyngeal sample was collected and an epidemiological questionnaire was completed. The study included 1562 children aged 1 and 4 years old. RESULTS: Almost one-third (31.3%, 489/1562) of children were nasal carriers. A sensitivity study was carried out on 376 isolates, of which 343 were serotyped. Almost two-thirds (61.7%, 964/1562) of children had received at least one dose of PCV7 (heptavalent pneumococcal conjugate vaccine), and 12.8% (44/343) of the isolates belonged to PCV7 serotypes. The prevalence rates of penicillin resistance (meningitis infections criteria CMI>0.06mg/L) were 28.1%; however, this percentage was 54% in PCV7 serotypes. None of the isolates had (MIC >2mg/L), so prevalence rates of susceptibility with non-meningitis infections criteria were 100%. There was a high percentage of erythromycin resistance (45.7%). The factors favouring resistance to penicillin and cefotaxime were the consumption of antibiotics in the previous month and the carrying of vaccine serotypes. On the other hand, the age of 4 years old was a protective factor of resistance. The 14, 35B, 19A, 15A, and 19F serotypes were less susceptible to penicillin. CONCLUSIONS: Both oral amoxicillin given to outpatients and intravenous penicillin or ampicillin to hospitalized patients are excellent options for the treatment of non-meningeal infections, as seen with pneumonia in these kinds of environments, where there is low incidence of isolates highly resistant to penicillin (CMI ≥ 2mg/L).

[Sarcoidosis in a sanitary area at Leon (Spain). Epidemiology and clinical features]. / Sarcoidosis en el área sanitaria de León. Epidemiología y clínica.

BACKGROUND: The incidence of sarcoidosis is different among distincts geographic areas, probably due to climate variations. At present, there is in Spain few studies that correlate the observed cases with a concrete population. The aim of this study is to investigate the epidemiology of sarcoidosis in Leon"s sanitary area, in comparison with others spanish geographic areas. Moreover, we present a description of the clinic and radiologic characteristics of the studied cases. METHOD: We analyzed the cases of sarcoidosis attended in the area from 1993 until 2001. The incidence, age, sex, place of residence and clinic-radiologic characteristics are described. The population data of the sanitary area to calculate the incidence were obtain from the Insalud"s data base. The climatology values were collected from the National Institute of Meteorology. RESULTS: The incidence of sarcoidosis in Leon"s sanitary area was 1,37/100.000 habitants/year, and was similar to that founded in Catalonia, Galizia and others provinces of the Castilla and Leon community. We observed a higher incidence of sarcoidosis in female patients, because of predominance of cases among women aged forty years or more. No differences between rural and urban populations were founded. The clinical characteristics were similar those described in other geographics areas of our country. CONCLUSION: Although there are climate differences between the geographics areas of Spain, these aren"t enough to explain his influence in the incidence of sarcoidosis, which is similar in all of them, at least in the middle north of the country.

[Listeria monocytogenes meningitis in the adult in Spain. Report of 10 cases and review of the literature]. / Meningitis por Listeria monocytogenes en el adulto en España. Presentación de 10 casos y revisión de la literatura.

INTRODUCTION: Ten new cases of Listeria monocytogenes meningitis (LMM) in the adult are here reported. Also, a review is made of reported cases by Spanish authors in the last 30 years, with an analysis of the predisposing conditions and mortality rate from this type of bacterial meningitis (BM) throughout the study period. METHODS: The reported cases met two criteria: CSF biochemistry consistent with BM and positive CSF and/or blood culture for Listeria monocytogenes. The bibliographic search of previously reported cases was made through Medline. Cases were divided into two periods: from 1974 to 1988, and from 1989 onwards. Predisposing conditions, therapy, and mortality were analyzed and compared between the two study periods. RESULTS: The features of the cases reported here did not differ from those in the cases reported so far, with the single feature of two HIV-positive patients. Of the analyzed cases, 73% had some predisposing condition. Thirty-eight and 39% of the total of patients and of patients with some predisposing conditions, respectively, died, with a statistically significant difference (p < 0.001) between those with and without predisposing conditions. Among the treated patients, 87% received either ampicillin or penicillin and the mortality rate among these patients was 30%. No differences regarding mortality was rate observed between the two study periods, the total of cases of between those treated with the aforementioned antibiotics. CONCLUSIONS: Patients with LMM commonly have a predisposing condition. The mortality rate in this type of BM is still high among those treated with ampicillin or penicillin, and a decrease in the mortality rate was not observed when the reported cases in Spain in the last 30 years were analyzed. The optimal therapy for this condition is still to be defined.

Human infection with Hymenolepis diminuta: case report from Spain.

We report a case of Hymenolepis diminuta infection in a human. The patient was a 5-year-old girl referred to us through the onset of a cyanotic attack. Treatment with a single dose (10 mg/kg of body weight) of praziquantel was ineffective, but the parasite was eradicated after three treatment cycles with the same drug at dosages of 25 mg/kg/day for 5 days.

[Bipolaris australiensis in a Spanish patient with allergic chronic sinusitis]. / Bipolaris australiensis en un enfermo Español con sinusitis alérgica crónica.

Allergic fungal sinusitis is a disease that results from hypersensitivity reaction of the host against fungi colonizing the paranasal sinuses. A 36 years old Spanish man with no history of travel abroad had a history of asthma, nasal polyps, allergic rhinitis and a chronic sinusitis with nasal congestion and headaches. Computed tomography showed pansinusitis and opacification of the paranasal sinuses. A pure culture of Bipolaris australiensis was grown from sinus tissues. Infections caused by Bipolaris spp. and treatment regimes are discussed.
