- Pneumococci isolated from blood and cerebrospinal fluid from 1998 to 2001 in 2 counties in south-west Sweden were serotyped with the capsular reaction test. Of the 836 strains, 353 (42%), 598 (72%) and 789 (94%) belonged to serotypes included in the 7- and 11-valent pneumococcal conjugate vaccines and in the 23-valent polysaccharide vaccine, respectively. The most common serotype was type 1 (119 isolates) followed in descending frequency by serotypes 7F, 9V, 14, 4 and 12F (90-49 isolates per serotype). The coverage rates of the 7- and 11-valent conjugate vaccines among 58 strains isolated from children and adolescents 0-19 y of age were 46% and 93%, respectively. A comparison of clinical characteristics of infections caused by different serotypes showed that types 1 and 7F were less commonly associated with severe underlying diseases, that patients infected with these serotypes were younger than the average and, thus, had a lower case-fatality rate.

Tidskriftsartikel (refereegranskat)abstract
- A 63-year-old man developed a left ventricular pseudoaneurysm 6 months after surgery for coronary artery disease, mitral valve insufficiency and left ventricular aneurysm. The grafts were patent and the mitral valve competent, so it was decided to resect the pseudoaneurysm. The heart was approached through a left posterolateral thoracotomy using a femoral arteriovenous cardiopulmonary bypass with moderate hypothermia (25 degrees C) and fibrillatory arrest. The postoperative course was uneventful. At follow-up, 55 months after surgery, the patient is doing well and magnetic resonance reveals absence of pseudoaneurysm and increased left ventricular ejection fraction. In patients with left ventricular pseudoaneurysm undergoing redo surgery, especially in the presence of patent coronary grafts, left thoracotomy seems to be a suitable alternative to full sternotomy.

- This study monitored the serotypes of Streptococcus agalactiae (group B streptococcus; GBS) isolated from invasive infections in western Sweden and investigated possible relationships between serotype, age and clinical manifestations. Invasive GBS isolates were collected prospectively during 1998-2001 at six laboratories, covering two counties with a population of 1.8 million, and were serotyped by coagglutination. Clinical data were obtained from hospital notes. In total, 161 invasive strains (50 from neonates and infants aged < 3 months, and 111 from adults) were serotyped. The commonest serotypes from neonates and infants were serotypes III (60%), V (22%) and Ia (10%), and from adults were serotypes V (42%) and III (25%). Serotype V had doubled in frequency among both children and adults compared to a previous study from the same area in 1988-1997. Most (80%) of the adults had an underlying medical condition. No relationship was found between serotype and clinical manifestations. However, the study demonstrated the importance of active surveillance of GBS serotypes and the difficulties of formulating a multivalent polysaccharide conjugate vaccine against GBS.
