HSVE in the immunocompetent host is a rare but distinct entity, and is significantly more common in male subjects. It represents either primary infection or reactivation, and is characterized by acute onset, systemic manifestations, and extensive erosive-ulcerative involvement of the mid-distal esophagus. Histopathological examination alone may miss the diagnosis; adding tissue-viral culture optimizes the diagnostic sensitivity. It is usually self-limiting; whether antiviral therapy is beneficial remains unknown.

SSI complicated 3.5% of the procedures. S. aureus was implicated in most of the cases and was significantly associated with deep SSI. It was the only pathogen associated with secondary bacteremia. In addition to standard guidelines, targeted methods against S. aureus should help reduce the overall rate of SSI.

Background: Pyogenic sacroiliitis occurs infrequently during the peripartum period. Case: A case at our institution and a review of the literature were analyzed. A total of 15 cases were discovered. The onset of illness was during pregnancy (40% of cases), within 3 weeks postpartum (40%) or post-abortion (20%), and the presentation was usually acute (< 7 days in 67% of cases). Frequent manifestations included localized pain in the hips or buttock, sacroiliac joint tenderness and fever. Computed tomography or magnetic resonance imaging revealed joint involvement in all cases tested. Microbiology was confirmed by blood (40%) or joint aspirate (75%), and most patients were treated with antibiotics. Surgical intervention took place in five cases. Preterm labor was reported in only one case. All patients responded well to therapy without locomotive disability, and persistent pain was uncommon. Conclusion: Septic sacroiliitis should be considered in peripartum patients who present with fever and severe localized pain. Medical management is usually curative, and without an adverse effect on pregnancy.

The faecal fungal flora was analysed in healthy volunteers and inpatients. Self-obtained stool swabs from volunteers (n = 228) and inpatient stool-samples (n = 34) were cultured on Inhibitory-Mould-Agar plates. All yeast isolates were identified. Fungi were detected in 51.8% of volunteers; the majority (88.1%) had single species. The prevalence increased steadily with age. Candida albicans was detected in 62.7%, non-albicans Candida species in 22.0%, yeasts--other than Candida in 20.3% and moulds in 8.5% of volunteers with fungi. No gender-related differences were noted in the prevalence or types of yeast. Candida glabrata and C. krusei were detected in adults only. Intra-household species-similarity (excluding C. albicans) was noted in seven of 31 (22.6%) households with fungi in two or more members. Inpatients had higher prevalence of yeast (88.2%) with a single species in the majority (73.3%). Yeasts other than Candida were less common in inpatients (3.3%; P = 0.013) whereas C. glabrata was significantly more prevalent (33.3 versus 2.5%; P < 0.001). This study delineates the faecal fungal flora in volunteers and inpatients. Most subjects harbour a single species that may be shared with other households. The prevalence is somewhat higher in adults and the types of yeast may vary with age. Finally, C. glabrata appears to be acquired nosocomially.

Guidelines for blood culture (BC) address the appropriate frequency, number and volume, but no guidelines exist for repeating BCs. The pattern of repeated BCs was studied in all patients hospitalised in December 2001 to determine the extent of and reasons for repeating cultures. BC was repeated in 127 (31.6%) of 405 adults with an initial BC during the study period. All patients with available records (n = 96; 75.6%) were included. The average patient age was 62.2 +/- 15.9 years. In total, 295 BC sets (one to four BCs/set) were obtained, comprising 96 initial and 199 repeats (one to nine repeats/patient). Sixty-nine (34.7%) repeats were taken within 24 h, and 89 (44.7%) within 2-4 days. The most common reason (32.2%) was persistent fever. The result of repeated cultures was: no growth (83.4%), same pathogen (9.1%), new pathogen (2.5%) or contamination (5.0%). Thus, BC repeats accounted for one-third of all BCs handled in the laboratory, with little additional yield. Guidelines for repeating BCs may decrease unnecessary testing.
