Huge Lipoma of Left Parotid Region with Intra-Parotid Extension.

Lipoma is a benign mesenchymal tumor originating from adipose tissue. The occurrence of this tumor in head and neck is less frequent and it rarely involves parotid gland. These are asymptomatic and occur both in the deep and the superficial lobe of the parotid. The most favored age group is from the fifth to sixth decade of life and is 10 times more common in the males. A 66-year-old male patient, with left parotid region lipoma is reported in this article. A fine-needle aspiration biopsy and ultrasonography were performed to establish the preoperative diagnosis and to plan the correct surgical approach. It was managed by surgical excision of lipoma with removal of cuff of superficial parotid tissue on superior aspect with preserving facial nerve. Follow-up examinations were planned to assess any facial nerve injury complications.

Sonographic assessment of placental migration in second trimester low lying placenta.

To assess the migration of low lying placenta diagnosed in the second trimester ultrasonogram (USG). All the women attending antenatal OPD clinic had undergone routine obstetric USG in the second trimester (14 weeks onwards). Those cases who had low lying placenta lower edge of placenta within 3.0 cms from the cervical internal os were included in the study. These cases were subjected to be followed up at 4 weekly interval to repeated serial ultrasonogram by Transabdominal and/or Transvaginal USG well through 3rd trimester of pregnancy or delivery which ever was earlier. Of the total 1229 second trimester USG, 312 (25.3%) women had low lying placenta in the second trimester. Follow up of this 312 cases indicated that in 288 (92.4%) cases it had migrated to upper segment by 3rd trimester. The migration of placenta was 92.4% and 68.0 % where the distance between the leading edge of placenta and cervical internal os was more than 2.0 cm or less than 2 cm respectively. Migration was not observed in women where the distance was less than 1.5 cm. Placental migration was 94.5% in anteriorly situated placenta and 90.2% in posteriorly situated placenta. The rate of placental migration was 95.1%, 77.7%, 55.5% in women who had previous normal delivery, previous caesarean delivery and prior history of dilatation and curettage (D & C) or manual removal of placenta (MRP), respectively. The prevalence of low lying placenta in 2nd trimester is 25.3%, which reduces to 7.3% at term. The rate of placental migration was over 90.0%. Factor like initial distance between the lower edge of the placental and cervical internal os. placental position and previous birth by caesarean section influence the placental migration.

Etiological agents of bacteraemia and antibiotic susceptibility pattern in Kathmandu Model Hospital.

The presence of bacteria in blood is simply known as bacteraemia. The main aim of this study is to determine the bacteraemia in patients visiting Kathmandu Model Hospital and antibiotic susceptibility pattern of isolates with special interest on ciprofloxacin. This prospective study was carried out in microbiology laboratory, Kathmandu Model Hospital from April 2005 to June 2005. Standard procedure was followed for blood sample collection. The bacteria were isolated and identified by standard microbiological procedure. Further, antibiotic susceptibility test was determined by NCCLS recommended Kirby-Bauer disc diffusion method. Out of 532 culture requests, 123 samples showed evidential microbial growth. The number of isolate of Salmonella typhi, Salmonella paratyphi A and Escherichia coli were 78, 44 and one respectively. The antibiotic susceptibility test demonstrated that chloramphenicol was the foremost drug of choice among the tested antibiotics with its sensitive rate of 98.4%. All the isolates of Salmonella typhi were susceptible to ceftriaxone and all isolates of Salmonella paratyphi A were susceptible to chloramphenicol, cotrimoxazole and amoxycillin. Ciprofloxacin resistant serotype of Salmonella was not isolated but out of 16 isolated serovar of Typhi and 10 serovar of Paratyphi A screened with nalidixic acid, 10 serovar of Typhi and all serovar of Paratyphi A were found to be resistant. Three isolates of Salmonella typhi were found as multidrug resistant (MDR) whereas no MDR was found in Salmonella paratyphi A. From this it can be concluded that Salmonella bacteraemia is more than other. Although nalidixic acid resistant serovars were isolated, ciprofloxacin resistant serovar were not present.
