Painful bilateral bipartite patellae--case report.

Bipartite patella is usually asymptomatic. Painful bipartite patella is either non-surgically managed by immobilization, anti-inflammatory drugs and physical therapy or treated by excision. We report a case in whom locally injected bupivacaine and steroid (methylprednisolone acetate) injection relieved the symptoms completely in a case of bilateral painful bipartite patellae.

GABA-A receptors in mPOAH simultaneously regulate sleep and body temperature in freely moving rats.

Sleep-wakefulness and body temperature are two circadian rhythmic biological phenomena. The role of GABAergic inputs in the medial preoptico-anterior hypothalamus (mPOAH) on simultaneous regulation of those phenomena was investigated in freely moving normally behaving rats. The GABA-A receptors were blocked by microinjecting picrotoxin, and the effects on electrophysiological parameters signifying sleep-wakefulness, rectal temperature and brain temperature were recorded simultaneously. The results suggest that, normally, GABA in the medial preoptic area acts through GABA-A receptor that induces sleep and prevents an excessive rise in body temperature. However, the results do not allow us to comment on the cause and effect relationship, if any, between changes in sleep-wakefulness and body temperature. The changes in brain and rectal temperatures showed a positive correlation, however, the former varied within a narrower range than that of the latter.

Pyelonephritic potential of Pseudomonas aeruginosa in ascending mouse model.

The suitability of female BALB/c and Swiss Webster (LACA) strains of mice for an ascending model of pyelonephritis for human uroisolate of Pseudomonas aeruginosa, was assessed. A fresh isolate of Ps. aeruginosa elaborating virulence factors like elastase, protease, phospholipase C, pyochelin and haemolysin was selected and introduced transuretherally in mice without any manipulation of the urinary tract. This isolate was able to colonize and persist in the renal tissue till day 12 post infection. Histopathologically, severe renal lesions i.e., abscesses formation was observed. The LACA strain was found to be more susceptible to infection with the selected Ps. aeruginosa isolate.

Implantation malignancy after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy may result in spillage of gall bladder contents during dissection or delivery of gall bladder through the umbilical port. We report a 50-year-old man who underwent laparoscopic cholecystectomy for suspected calculous cholecystitis. Histology showed a single focus of adenocarcinoma in the gall bladder. There was spillage of gall bladder contents at the umbilical port during delivery. Six months later, he developed adenocarcinoma at the port site. This was treated by wide excision.

Drug resistant Haemophilus influenzae from respiratory tract infection in a tertiary care hospital in north India.

Haemophilus influenzae is an important respiratory pathogen. Emergence of resistance to various antibiotics is a major problem in patient management. A total of 90 strains of H. influenzae were characterized from specimens obtained from patients of acute respiratory tract infection; 13 (14.4%) belonged to type beta. On biotyping, 90% strains belonged to biotype II. The frequency of resistance to various antibiotics was as follows: cotrimoxazole 33.3% ampicillin 21.1%, cephalexin 7.8%, chloramphenicol 7.8%, ciprofloxacin 2.5% erythromycin and tetracycline 5% each. All the ampicillin-resistant strains produced beta-lactamase as detected by nitrocefin disc method. None of the strains exhibited resistance to cefaclor and third generation cephalosporins. The present study showed emergence of variable resistance to ampicillin, cotrimoxazole and other antibiotics. It is important for the clinical microbiology laboratory to monitor drug resistant strains for instituting appropriate antibiotic therapy of respiratory infections due to H. influenzae.
