ABSTRACT
During 2007, a study of pneumococcal carriage in children was performed in two towns (Trinidad and Riberalta) in the Beni region of the Bolivian Amazon basin. Little has previously been reported regarding the epidemiology of pneumococcal carriage in Bolivia, and no multilocus sequence typing (MLST) of pneumococcal isolates from this region has previously been documented. A pneumococcal carriage rate of 34% was identified. Of 53 Streptococcus pneumoniae isolates that survived transportation for serotyping, antibiotic susceptibility testing and MLST, the commonest serotypes were 6A (9%), 34 (8%), 4 (6%), 9A (6%), 10A (6%), 19A (6%), 23F (6%) and 38 (6%); overall, 26 different serotypes were identified. Antibiotic susceptibility testing by Etest demonstrated high levels of susceptibility to penicillin (93%), erythromycin (98%), vancomycin (100%), chloramphenicol (100%), tetracycline (96%) and trimethoprim/sulfamethoxazole (co-trimoxazole) (85%). MLST identified that the majority (57%) of viable isolates belonged to previously unrecognised sequence types that are currently unique to Bolivia.

Anecdotal evidence from several ENT departments suggests that pain following tonsillectomy is worst on the second and/or third days after surgery. This study tests this hypothesis. A pilot study with 19 subjects suggested this theory might well be true. A fuller study was then carried out on 91 subjects with standardised surgical and anaesthetic techniques, and standardised analgesia for five days postoperatively. Pain on the second and third postoperative days was compared with that eight hours after the operation and on the first, fourth and fifth postoperative days. No statistically significant difference was found. There is increasing pressure for early discharge from hospital after surgery. If pain following tonsillectomy is not going to become worse at home, this will tend to make early discharge more acceptable to patients.

Giant polypoidal hamartomas of the pharynx and oesophagus are rare benign tumours of unknown origin, exceptionally arising from the oropharynx. We report the case of a 74-year-old man who developed sudden nausea and a foreign body sensation. Shortly afterwards he regurgitated a 25 x 3 x 1.5 cm pedunculated fleshy mass, still attached to the inside of his thorat. The patient was anaesthetised, the mass traced to the right tonsillar fossa and adjacent oropharyngeal wall. The pedicle was clamped and the lesion excised. Histology was consistent with a giant oropharyngeal hamartoma. We discuss the pathogenesis and potential complications of this condition. The literature is reviewed.
