The utility of toluidine blue staining and brush cytology as adjuncts in clinical examination of suspicious oral mucosal lesions.

The objective of this study was to investigate the utility of toluidine blue and brush cytology in patients with clinically detected oral mucosal lesions. Clinical examination of 35 patients was completed before toluidine blue application, oral brush cytology and scalpel biopsy. Lesions were photographed before and after stain application; followed by brush cytology. All findings were compared with histopathologic results. Severe dysplasia and carcinoma-in-situ were determined as 'positive'; no dysplasia and mild to moderate dysplasia were defined as 'negative'. The sensitivity, specificity, positive and negative predictive values of clinical examination and toluidine blue were the same: 0.923, 0.433, 0.414, and 0.929, respectively. Those of brush cytology were 0.923, 0.517, 0.462, and 0.938. The concordance of all methods was 30% for benign and 61% for malignant lesions. Adjuncts identified 92% of carcinoma-in-situ and squamous cell carcinoma as confirmed by histopathology, in contrast to clinical findings alone in which 62% of these lesions were identified (p=0.046). In conclusion, adjunct diagnostic methods decreased the level of uncertainty for the diagnosis of oral malignancies and lichenoid dysplasias when applied as adjuncts to clinical examination.

Vaginal fluid pH, cervicovaginitis and cervical length in pregnancy.

AIM: The purpose of this prospective study was to determine the possible association among vaginal fluid pH, cervicovaginitis and cervical length in singleton pregnancies at 16-22 weeks of gestation. METHODS: A total of 240 asymptomatic singleton pregnancies at 16-22 weeks of gestation were included to the study. Vaginal fluid pH was determined using pH paper in a sterile speculum examination, and cervical length was examined by transvaginal ultrasonographic measurement. Vaginitis was diagnosed by pH determination and wet mount smear; cervicitis was diagnosed by cervical examination. Patients were followed to delivery and hospital records were reviewed to extract obstetric information. Preterm delivery was defined as delivery at or prior to 36 weeks of gestation. Abnormal pH was defined as a pH of > 5.0. Patients with cervicovaginitis (n = 72) were compared with those without any trace of infection (n = 60). RESULTS: The mean gestational age was 20.3 +/- 1.4. We found an significant association among cervicovaginitis, cervical length and vaginal pH. There was a significant correlation between an elevated vaginal pH (> 5.0) and a shortened cervical length (r = -0.59, p < 0.001). Vaginal fluid pH > 5.0 was associated with increased risk of preterm delivery (OR 4.3, 95% CI 2.0, 9.3; p = 0.001) as well as delivering an infant of less than 2,500 g (OR 4.0, 95% CI 1.4, 11.0; p = 0.009). CONCLUSIONS: Elevated vaginal fluid pH in women at 16-22 weeks of gestation seems to be associated with a decreased cervical length and increased risk of preterm delivery.

Evaluation of LOOP electrosurgical excisional procedure: case series.

OBJECTIVE: To evaluate the loop electrosurgical excisional procedure (LEEP) which is performed to treat high-grade cervical intraepithelial lesions (HGSIL). MATERIAL AND METHODS: Twenty-one cases diagnosed as LGSIL and HGSIL after histopathological examination were included in the study among patients who had cervical colposcopy-directed biopsies after an abnormal cytology report at Ege University School of Medicine, Obstetrics and Gynecology Department between the years of 2007 and 2009. The patients underwent LEEP or LEEP-cone procedures. RESULTS: The patients with cervical smear results of ten ASCUS, eight LGSIL, and three HGSIL underwent colposcopy-guided punch biopsies. Those with the result of CIN 1 and CIN 2 underwent LEEP or LEEP-cone procedures. Pathologic examination correlated with biopsy results and surgical margins were all negative. All patients were followed-up with cervical cytology. CONCLUSION: LEEP and LEEP-cone procedures are therapeutic procedures in cervical intraepithelial lesions.

Abdominal skin metastasis of endometrial adenocarcinoma: case report.

Skin metastasis from endometrial adenocarcinoma in the radiotherapy field is reported. A 60-year-old woman with FIGO stage IB, grade 2 endometrial adenocarcinoma presented 24 months after initial surgery with skin metastasis located on the abdomen.

The effect of non-surgical periodontal and adjunctive minocycline-HCL treatments on the activity of salivary proteases.

The purpose of this investigation was to evaluate the effect of non-surgical periodontal treatment and adjunctive systemic minocycline therapy on the level of neutral protease activity in whole saliva of adults with periodontitis. A test group of 21 adult patients with moderate to severe periodontitis was compared to a control group of 5 adults with healthy periodontium. Four test groups were examined: 1) scaling and root planing (SRP), probing depth = 4 to 5 mm; 2) SRP, PD > or = 6 mm; 3) SRP and adjunctive systemic minocycline therapy, PD = 4 to 5 mm; 4) SRP and adjunctive systemic minocycline therapy, PD > or = 6 mm. Clinical parameters and levels of neutral protease in whole saliva were assessed at baseline and on the sixth week after the non-surgical periodontal treatment. Neutral protease activity was measured by spectrofluorimetric method. Statistical tests of Mann-Whitney and Spearman Rank correlation coefficient were used in the evaluation of the mean values of measurements. The mean values of protease activity were significantly higher in the test groups than in the control group at baseline. Six weeks after non-surgical therapy, patients with 4 to 5 mm probing depth had approximate values of protease activity comparable to the control group. Hence it can be argued that these patients did not need minocycline HCL as an adjunctive therapy. However, non-surgical therapy had limited effects on both clinical parameters and enzyme activities for subjects with > or = 6 mm probing depth; on the other hand, gingival inflammation and enzyme activities were reduced significantly by the usage of minocycline as adjunctive therapy in these patients. According to our results, neutral protease activity in saliva is related to probing depth and gingival bleeding index, and not related to age and epithelial cell number. For these reasons, systemic minocycline therapy might be useful as an adjunct to non-surgical therapy in the presence of deep pockets, especially for reinfected cases. Further investigations are needed to confirm this suggestion.
