Prospective comparison of loop excision under colposcopic guidance versus vitom guidance

Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (T1) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done respectively, followed by endocervical curettage. Volume of removed tissue, complications, and positive resection margins were compared for the colposcopy and the VITOM groups. Findings: Demographic and reproductive features were similar between groups. In the VITOM group 49% of patients had zone T1, 30% had zone T2, and 21% had zone T3. In the group of patients managed by colposcopy, 48, 45, and 7% of patients had zone T1, T2 and T3 zone, respectively (p0.05). There were no significant differences in the type of procedure or the mean volume of removed tissue. Results were similar for both groups with respect to positive resection margins and complications. Conclusion: VITOM is a safe and reliable system. Results using the VITOM system are comparable to those obtained with conventional colposcopy. The potential advantage of VITOM is the broader availability of endoscopic systems in the operating theatre. © Georg Thieme Verlag KG Stuttgart · New York

Defensive properties of pyrrolizidine alkaloids against microorganisms

The understanding of the selection factors that drive chemical diversification of secondary metabolites of constitutive defence systems in plants, such as pyrrolizidine alkaloids (PAs), is still incomplete. Historically, plants always have been confronted with microorganisms. Long before herbivores existed on this planet, plants had to cope with microbial pathogens. Therefore, plant pathogenic microorganisms may have played an important role in the early evolution of the secondary metabolite diversity. In this review, we discuss the impact that plant-produced PAs have on plant-associated microorganisms. The objective of the review is to present the current knowledge on PAs with respect to anti-microbial activities, adaptation and detoxification by microorganisms, pathogenic fungi, root protection and PA induction. Many in vitro experiments showed effects of PAs on microorganisms. These results point to the potential of microorganisms to be important for the evolution of PAs. However, only a few in vivo studies have been published and support the results of the in vitro studies. In conclusion, the topics pointed out in this review need further exploration by carrying out ecological experiments and field studies

Evaluation of Effect of Taxus baccata Leaves Extract on Bronchoconstriction and Bronchial Hyperreactivity in Experimental Animals

The present investigation was undertaken to evaluate the bronchodilating effect and bronchial hyperreactivity of alcoholic extract of Taxus baccata Linn. (AET) leaves in experimental animals. Bronchodilator activity of AET was studied on the histamine and acetylcholine aerosol induced bronchospasm in guinea pigs and bronchial hyperreactivity was studied on bronchoalveolar lavage fluid (BALF) in the egg albumin sensitized guinea pigs and by histopathological studies. In vitro mast cell stabilizing activity was studied using compound 48/80 as a degranulating agent. Treatment with AET (200 and 400 mg/kg, p.o., for 7 days) showed significant protection against histamine and acetylcholine aerosol induced bronchospasm in guinea pigs. Significant decrease in the total leukocyte and differential leukocyte count in the BALF of the egg albumin sensitized guinea pigs was observed by administration of AET (200 and 400 mg/kg, p.o., for 15 days). AET dose dependently protected the mast cell disruption induced by compound 48/80. These results suggest that AET not only has bronchodilating activity but also decreases bronchial hyperreactivity by decreasing the infiltration of inflammatory cells in the airway and inhibiting the release of histamine like mediators from the mast cell by stabilizing it

Italian guidelines for primary headaches: 2012 revised version

The first edition of the Italian diagnostic and therapeutic guidelines for primary headaches in adults was published in J Headache Pain 2(Suppl. 1):105–190 (2001). Ten years later, the guideline committee of the Italian Society for the Study of Headaches (SISC) decided it was time to update therapeutic guidelines. A literature search was carried out on Medline database, and all articles on primary headache treatments in English, German, French and Italian published from February 2001 to December 2011 were taken into account. Only randomized controlled trials (RCT) and meta-analyses were analysed for each drug. If RCT were lacking, open studies and case series were also examined. According to the previous edition, four levels of recommendation were defined on the basis of levels of evidence, scientific strength of evidence and clinical effectiveness. Recommendations for symptomatic and prophylactic treatment of migraine and cluster headache were therefore revised with respect to previous 2001 guidelines and a section was dedicated to non-pharmacological treatment. This article reports a summary of the revised version published in extenso in an Italian version

CLINICAL AND EXPERIMENTAL OBSTETRICS & GYNECOLOGY

Purpose of investigation: To study adrenomedullin (ADM) in preventing ischemia and morphological changes in heterotopically transplanted ovary. Materials and Methods: Forty female Sprague-Dawley rats were divided into four groups. In groups 1 and 2 each ovary was transplanted to the corresponding inguinal region by heterotopic transplantation. In groups 3 and 4, ovaries were left intact without transplantation. Treatment was injected to left inguinal region. ADM was given in groups 1 and 3 and placebo was given in groups 2 and 4. Left ovaries showing local treatment effect in heterotopic transplantation was designated as A (1A, 2A, 3A, and 4A), right ovaries showing systemic treatment effect were designated as (1B, 2B,3B, and 4B). Main outcome measures were ischemia, follicle count, and CD 31 expression. Results: Ovaries treated with local ADM (group 1A) were in consonance with normal rat ovaries. The ovaries of rats in group 1B and placebo treated transplant group (groups 2A, 2B) exhibited varying effects of ischemia. The mean follicle numbers in groups 1A, 1B, 2A, 2B were 28 3.3, 16.8 2.5, 17.7 2.1, 16.4 2.9, respectively. The mean follicle number in groups 3A, 3B, 4A, and 4B were 27.7 2.0, 28.3 2.2, 28.3 2.2, 27.8 1.9, respectively. Corpus luteum number and CD31 expression was found to be significantly higher in group 1A. Conclusion: Subcutaneous injection of ADM to heterotopic ovarian graft site causes vasodilatation and increases angiogenesis and may protect ovarian graft against hypoxic damage

Laparoscopic Management of External Iliac Artery Injury Using Yasargil Clamps and Intracorporeal Suture

Presented is a case report of laparoscopic repair of an external iliac artery injury using titanium Yasargil clamps and intracorporeal suture during lymphadenectomy. Yasargil clamps were introduced and placed, 1 distal and 1 proximal to the lesion. The vascular injury site was identified and repaired using intracorporeal sutures. Laparoscopic staging was completed successfully. No sign of thrombosis or vascular occlusion was detected. The patient was discharged on postoperative day 4 to receive adjuvant therapy. Laparotomy is the accepted way of managing major vascular injuries during laparoscopy. However, in controlled circumstances, with availability of Yasargil clamps and a surgeon experienced with intracorporeal suturing, immediate laparoscopic repair of major vascular injury is feasible and is a safe alternative to open surgical repair. © 2011 AAGL
