[Hospitalizations for varicella in the Hospital Infantil La Fe, Valencia,Spain, 2001-2004]. / Hospitalizaciones por varicela en el Hospital Infantil La Fe (Valencia 2001-2004).

INTRODUCTION: Varicella is a common, highly contagious disease. It is usually benign but has potentially serious complications. PATIENTS AND METHODS: To assess the clinical characteristics and the associated cost of varicella hospitalization, we reviewed the medical records of children hospitalized for varicella between 2001 and 2004. Children with coincidental varicella hospitalized for a different reason were excluded. RESULTS: Of 1177 children with varicella attended at the emergency room, 101 (8.6 %) were hospitalized. The median age was 3.2 years (21 days to 18.9 years). Twenty-eight children had underlying disease. Thirty-seven children had no complications and the reason for admission was: a) risk of severe varicella (21 immunocompromised children, three neonates), and b) high fever or observation (13 cases). The 64 remaining children were admitted for 66 complications of varicella. The most common complications were skin/soft tissue infections (33 patients) and the leading cause was Streptococcus pyogenes (n = 13) and Staphylococcus aureus (n = 10) isolated in blood or the site of infection. Other complications were pneumonia (13 children), neurological (febrile seizures in nine, meningoencephalitis in two, acute disseminated encephalomyelitis in one, cerebellitis in one), hematological (neutropenia in one, Henoch-Schönlein purpura in one and thrombopenic purpura in three) and osteoarticular (synovitis in one and septic arthritis in one). One patient died of multiorgan failure. During the study period, the rate of emergency room visits due to varicella doubled and the number of admissions for complications tripled. The mean length of hospital stay was 6.8 days (range: 1-28 days) and the total associated cost was 397,314.14 Euro, excluding symptomatic treatment. CONCLUSIONS: The high morbidity associated with varicella and its complications, as well as the high social costs of this disease, support the implementation of routine varicella vaccination. This could reduce the total number of cases, their severity, direct costs, generated by medical care, and indirect costs, generated by the disease and hospitalization.

[Skin and soft tissue infections caused by Haemophilus influenzae type b over a 30 year period]. / Infecciones graves de piel y tejidos blandos por Haemophilus influenzae tipo b a lo largo de 30 años.

INTRODUCTION: The skin and soft tissue infections caused by Haemophilus influenzae type b (Hib) are usually mild but can be potentially serious due to the high probability of bacteremia. Prompt instauration of empiric intravenous antibiotic therapy according to the localization and characteristics of the lesion is mandatory to prevent severe complications. PATIENTS AND METHODS: Of 257 children admitted to the Children's Hospital of La Fe due to invasive Haemophilus influenzae type b disease (1973 to 2003), we reviewed 15 cases (5.8%) of skin and soft tissue infections, their outcome, complications and sequelae. RESULTS: Ten children (66.7%) were aged < 2 years old. In eight patients (53.3%) there was a history of upper respiratory tract infection. Localization was in the head in 9 children (60%) and blood culture was positive in 10 patients (66.7%). Meningitis was a complication in 2 children (13.3%) and limited mobility of the hand was a sequel in one child (6.6%). After the universal establishment of the Hib vaccine in 1997, 3 new patients were admitted; 2 children with an infected thyroglossal cyst and another with cellulitis in the left leg. Of these children, one had received only the three primary doses of the vaccine but not the booster dose, and the remaining two were unvaccinated immigrant children. CONCLUSION: Skin and soft tissue infections caused by Hib are potentially severe diseases with a risk of complications and sequelae. Due to the increase in unvaccinated immigrants and possible vaccine failures, universal immunization and epidemiological surveillance of carriers should be carried out to achieve total eradication.
