ABSTRACT

Background: Breast lump is the most common presentation of the breast disease. Fine needle aspiration cytology (FNAC) is a simple, rapid and safe, method to diagnose the breast lesions.The objective of thisstudy was to determine the cytomorphological patterns of various breast lesions diagnosed on FNAC. Methods: This study was conducted on 280 patients presenting with breast lump over a period of 3 years.Results: The age range of these patients was from 11-80 years. Female patients were more than male patients. Left breast involvement was more common than the right breast. The cytological diagnosis included benign breast disease (C2-88%), atypical/probably benign (C3-1%), suspicious for malignancy (C4-3%), malignant (C5-8%). Fibroadenoma and invasive ductal carcinoma were most common among benign and malignant lesions respectively.Conclusions:The primary goal of aspiration cytology is to separate malignant lesions from benign ones and it also makes an important tool in guiding further management of a case. So, it is concluded that FNAC should be used as a routine diagnostic procedure due to its cost effectiveness and quick results, thus maximizing the availability of effective health care to patientswith breast lesions.

ABSTRACT

Objective: To assess normal conjunctival cytological and bacteriological/fungal flora features in the Mediterranean buffalo (. Bubalus bubalis). Methods: Swabs were taken from the inferior conjunctival sac of both eyes of 57 healthy female buffaloes aged 24-36 months, with no evidence of ocular disease, farmed in Campania region (Southern Italy), for microbiological analysis. Conjunctival eye specimens of both eyes were subsequently obtained by a cyto-brush, for cytological analysis. The antimicrobial susceptibility of bacterial isolates was also determined using the disk-diffusion method on Mueller Hinton agar plates. Results: Cytological examination of conjunctival swab specimens (114 eyes) revealed epithelial cells (basal, intermediate, columnar and superficial) in all samples, whereas neutrophils, lymphocytes and plasma cells were present in 70%, 10% and 2% of samples, respectively. Microorganisms, for a total of 261 aerobic bacteria and 6 fungi, were isolated from 112/114 conjunctival samples [98.25%; 95% confidence interval (. CI): 93.18-99.70]. Only two conjunctival swabs did not yield bacteria and/or fungi (2/114, 1.75%; 95% CI: 0.30-6.82). Gram-positive aerobes were most commonly cultured (181/261, 69.35%; 95% CI: 63.31-74.81), with Enterococcus faecium and Staphylococcus lentus predominating. Escherichia coli was the most frequently isolated as Gram-negative bacteria (80/261, 30.65%; 95% CI: 25.19-36.69). The antimicrobial resistance patterns of the isolated bacteria showed amoxycillin/clavulanic acid and cephalothin as the least sensitive antibiotics for both Gram-positive and Gram-negative bacteria. Conclusions: These results provided first information on normal conjunctival ocular microflora and cytological features in Mediterranean buffalo.

ABSTRACT

@#ObjectiveTo observe and evaluate the role of cervical cytological examination in 1946 cases in gestation, and at 2 months and 6 months after delivery, and treatment for abnormal cases.MethodsThe thinprep cytologic test samples of 1946 cases from external cervical orifice and cervical cavity were collected. The cytological diagnosis was performed according to TBS-diagnosis and classification system.ResultsIn 1946 samples, there were 160 inflammatory samples (8.2%), including bacterial vaginitis 51 cases (2.6%), trichomonal vaginitis 49 cases (25.%), candidal vaginitis 58 cases (3.0%); typical epithelial cells 105 cases (5.4%), including atypical squamous cells (ASUCS) 70 cases (3.6%), low-grade squamous intraepithelial lesions (LSIL) 29 cases (1.5%), high-grade squamous intraepithelial lesions (HSIL) 5cases (0.2%), the carcinoma in situ 1 case (0.05%); human papilloma virus (HPV) 32 cases (1.6%), including HPV combined with atypical squamous cells 21 cases (1.1%), HPV combined with LSIL 10 cases (0.5%). Large mass of cases with a abnormally result of cervical cytological examination had a normal childbearing, the cases that re-examination after birth showed carcinoma in situ and HSIL treated by conization, and others treated with physical treatment.ConclusionCervical cytology examination has positive effect on prevention and treatment of precancerous changes and carcinoma in gestational women. Cervical lesions less likely get worse during pregnancy. Conservative management is possible if regular cytology, copolscopy and bioposy performed when necessary. Re-examination at two and six months after birth is necessary for determining treatment method.
