Abstract
Background and Objective: Neonatal sepsis is a remarkable factor in mortality, morbidity, neonatal and perinatal complications. Group B Streptococcus (GBS) is the primary cause of invasive disease in infants and pregnant women. This study aimed to determine the relationship between antimicrobial resistance of the bacteria colonized in the vagina and rectum of pregnant women and early neonatal infection.
Material and Methods: In this prospective study conducted on 282 pregnant women, bacterial sensitivity to ampicillin, cefazolin, erythromycin, vancomycin, gentamicin, amikacin was measured. Furthermore, the relationship between rectal and vaginal colonization of mothers and early neonatal sepsis was evaluated.
Results: Of 98 positive rectal cultures, 49 (50%) were Gram-positive cocci and 49 (50%) E.coli. of 143 positive vaginal cultures, 136 (95.1%) were Gram-positive cocci, 7 (4.9%) were E.coli and two were positive GBS. We could find definitive neonatal sepsis. Significant correlation was found between a history of urinary tract infection and the mother's positive rectal culture (P =0. 03).
Conclusion: Clinical sepsis in neonates is correlated with positive rectal culture (P =0. 001) and the positive E.coli vaginal cultures is associated with suspected neonatal sepsis (P =0.007). Gram-positive cocci were resistance to ampicillin and gentamicin, and E.coli was resistant to ampicillin, erythromycin and vancomycin. Because of resistance to ampicillin, we recommend cefazolin due to its sensitivity to organisms and safety in pregnancy.

Abstract
ABSTRACT
Background and Objectives: Tonsils are lymphoid tissues that can be affected in various diseases. In some cases, it is necessary to remove tonsils through surgery. Although the diseases are often diagnosed by history-taking and physical examination that proceeds with surgery, histologic examination is necessary for confirmed diagnosis of malignancy. Considering the low prevalence of tonsil cancer, this study was performed to clinically examine tonsils for malignancies and evaluate the necessity of histopathological examination.
Methods: This retrospective study was conducted on 2,232 patients (aged 2-80 years) who had undergone tonsillectomy for various reasons in the city of Gorgan from 2001 to 2012. Medical history was obtained and physical examination was carried out before surgery. All the obtained samples were sent to the laboratory for histopathological examination. Finally, the collected data was analyzed.
Results: Only one case of lymphoma was found among the 2,232 patients investigated in this study. This 80-year-old woman with preoperative cervical lymphadenopathy and unilateral tonsillar enlargement went under tonsillectomy for confirmed diagnosis.
Conclusion: Considering the high frequency of tonsillectomy and the low possibility of malignancy, and the fact that malignancy is often seen in individuals with obvious clinical presentations such as in our case, it is recommended to limit referral of specimens for histological examination to highly suspicious cases through more rational decision-making and summarization of other findings.
