RESUMEN
This is a prospective study with the aim to determine specific patterns of burn wound bacterial colonisation and antimicrobial resistance profiles. There is a high incidence of infections and septicaemia in post-burn patients, which, in turn, are associated with high morbidity and mortality, a fact that compelled us to undertake this study. The study was conducted over a period 11 months, from 1 August 2014 to 30 June 2015, in 50 burn patients admitted in our burn unit. Wound cultures were taken after 72 hours of admission from all the patients, and then, empirical systemic antibiotics were administered. For wound cultures; 1 cubic cm tissue was taken and placed in aerobic and anaerobic culture vials and transported to the microbiology lab under all aseptic precautions as soon as possible. At the time of fever any time after 72 hours of admission, 16 ml of blood was drawn under all aseptic precautions. Both aerobic and anaerobic blood culture vials were filled with 8 ml of blood each and transported to the microbiology lab. The results of culture and sensitivity reports of 50 patients were recorded. The data obtained was analysed using appropriate statistical analytical tests. The most common organism responsible for bacteraemia is Pseudomonas (43%). Most of the strains of organisms isolated were resistant to commonly used antibiotics in the hospital; Pseudomonas was found 100% resistant to a combination of ampicillin + sulbactum, ceftriaxone and was most often sensitive to imipenem, amikacin and vancomycin. Methicillin-resistant Staphylococcus aureus (MRSA) was also found resistant to commonly used antibiotics like ceftriaxone, ampicillin + sulbactum and ceftazidime + calvulanic acid. Linzolid and vancomycin were effective in 83% and 100% cases, respectively. We conclude that similar institution-specific studies should be conducted, and such studies will be helpful in providing useful guidelines for choosing effective empirical therapy that will have a great impact on the prevention of infection and its complications in burn patients because of bacteraemia.

Ameloblastic carcinoma is a rare aggressive malignancy of odontogenic epithelial origin. The disease has been reported to afflict people over a wide range of age group without any sex predilection. It is characterized by rapid growth and destruction of overlying bones along with involvement of adjacent soft tissues. The overall prognosis of this cancer is poor despite radical surgery and radiotherapy. Owing to the rarity of this lesion, complete data on the biological behavior and response to different treatment modalities are still lacking. The authors hereby report a case of this uncommon tumor arising from left maxilla in a 60-year-old Indian male. Histopathological examination of the tumor showed foci of spindling intermixed with large areas of tumor cells arranged in cribriform pattern and having luminal eosinophilic material which was reminiscent of adenoid cystic carcinoma. A final diagnosis was achieved after immunohistochemical study. These unusual findings prompted this case report.

To establish the role of fine-needle aspiration cytology (FNAC) as a diagnostic tool for non-Hodgkins lymphoma in a resource challenged environment. This study was conducted on patients with lymphadenopathy, attending various clinics over a period of 18 months. FNAC of the enlarged lymph nodes was performed and biopsy, special stains and immunohistochemical staining was done in selected cases. Out of the total 275 cases, 42 cases (16%) were primary lymphoproliferative disorders. Non-Hodgkin lymphoma comprised of 32 cases (76.2% of all lymphomas), Hodgkin lymphoma-10 cases and the rest were metastatic carcinoma. The diagnostic accuracy for non-Hodgkin Lymphoma was 93.3%, sensitivity 95.4%, and specificity 87.5%. FNAC is a rapid, safe, easy, and nonexpensive diagnostic technique which can be used for early diagnosis of non-Hodgkins lymphoma.
