Acurácia da histerossonografia versus ultrassonografia transvaginal em mulheres inférteis candidatas às técnicas de reprodução assistida

PURPOSE: To compare the diagnostic accuracy of sonohysterography (HSN) and conventional transvaginal ultrasound (USG) in assessing the uterine cavity of infertile women candidate to assisted reproduction techniques (ART). METHODS: Comparative cross-sectional study with 120 infertile women candidate to ART, assisted at Centro de Reprodução Assistida (CRA) of Hospital Regional da Asa Sul (HRAS), Brasília-DF, from August 2009 to November 2010. Sonohysterography was performed with saline solution infusion in a close system. The sonohysterography finding was compared to previous USG results. The uterine cavity was considered abnormal whenthe endometrium was found to be thicker than expectedduring the menstrual cycle and whenan endometrial polyp, a submucous myoma and an abnormal shape of the uterine cavity were observed. The statistical analysis was doneusing absolute frequencies, percentage values and the χ 2, with the level of significance set at5%. RESULTS:HSN revealed that 92 (76.7%) infertile women candidate to ARThad anormal uterine cavity, while 28 (23.3%) had the following abnormalities: 15 polyps (12.5%).

Clinical diagnosis and histological analysis of vocal nodules and polyps

Recent studies emphasize the importance of the clinical-histology correlation in laryngeal pathologies. Objective: To compare the ENT diagnosis with the pathology diagnosis one of 132 surgical specimens, from 119 patients with vocal nodules and polyps. Method: Retrospective study. We investigated the paraffin blocks corresponding to the lesions of the operated patients. We made new histology cross-sections, totaling 396 new slides, divided into three groups: hematoxylin and eosin, Gomori trichrome and PAS. We analyzed the following histological parameters: epithelium, lamina propria, basement membrane, vascular changes. We compared the laryngological and pathological diagnoses, and we did the statistical analysis, checking the predominant histological aspects in each lesion. Results: There was an agreement between the clinical and pathological diagnoses in 123 (93.18%) of 132 lesions analyzed (42.42% nodules and 50.76% polyps). In the histological parameters we found: epithelial changes such as nodules hyperplasia (82.14%) and polyp atrophy (31.34%). Lamina propria: edema in polyps (71.43%), fibrosis in the nodules (57.14%). Basement membrane: thickened nodules (100%), thin/no change in polyps (100%). There was a predominance of vascular changes in the polyps. Conclusion: We found a high correlation between the ENT diagnosis and the pathology report. Histopathologically, the nodules presented with predominantly epithelial changes, lamina propria and basement membrane fibrosis, while the polyps by changes strictly on the lamina propria and vascular aspects.

Mass occurrence of the cubomedusa Copula sivickisi (Cnidaria: Cubozoa) at Seto Harbor, Shirahama, Wakayama, Japan in summer of 2013, a recent example of global warming

More than 200 very young medusae of Copula sivickisi (Stiasny) were collected within totally 60 minutes at two nights in June, 2013 at the Seto Harbor, Shirahama, Wakayama, Japan. This mass occurrence might be related to recent global warming at Shirahama, known as the northernmost distributional locality of this cubozoan species. It is assumed that the polyp stage of this species may live in the surrounding areas, because there jellyfish were small size (most are less than 1.6 mm height) that was conceivable as the newly released one from the polyp.

Avaliação da cavidade uterina com histerossonografia, uma revisão

Sonohysterography was firstly described three decades ago. The saline solution infusion into the uterine cavity favors its use and provides excellent visualization of the anatomy and the inner cavity of the uterus better than the conventional transvaginal sonography To check the current role of sonohysterography in the uterine cavity assessment in women with abnormal uterine bleeding and asymptomatic, a literature review comparing sonohysterograph with conventional transvaginal sonography and/or ambulatory diagnostic hysteroscopy was carried out. To this end, relevant studies were researched in electronic databases Medline/PubMed, SciELO/LILACS. The sonohysterography is an ambulatory procedure, non-invasive, better cost-benefit, better sensitivity and specificity to identify uterine abnormalities, causing minimal discomfort and low complications rate. It was subject to revision which there is no more doubt about its accuracy. It can be concluded that the sonohysterography is a useful tool in the propedeutics to assess uterine cavity of symptomatic patients with abnormal uterine bleeding, infertility, recurrent miscarriages, and embryonic implantation failures in assisted reproduction treatment / in vitro fertilization and in any other intra and extra uterine cavity alteration. Hence, conventional transvaginal sonography is indicated as an initial method of assessment of the uterine cavity previously to ambulatory diagnostic hysteroscopy.

Discovery and redescription of type material of Nausithoe simplex (Kirkpatrick, 1890), comb. nov (Cnidaria: Scyphozoa: Coronatae: Nausithoidae) from the North Atlantic

With discovery and examination of type specimens in the Natural History Museum, London, UK, we reassign Stephanoscyphistoma simplex (Kirkpatrick, 1890) to the genus Nausithoe Kolliker, 1853, as Nausithoe simplex, comb. nov., and designate a lectotype for the species. Use of morphometric measurements is considered important in coronate systematics, but key features also include the unique whorl of internal cusps and the shape of these cusps. All previous records of N. simplex must be re-evaluated, taking into consideration the morphology of these internal cusps.

Suppression of Inflammatory Cytokine Secretion by an NF-kappa B Inhibitor DHMEQ in Nasal Polyps Fibroblasts

Background: NF-kappa B is an essential transcription factor strongly associated to inflammatory response in chronic rhinosinusitis with nasal polyps (CRSwNP). DHMEQ is a NF-kappa B inhibitor that has been previously described with a greatpotential indecreasing inflammation in diseases other than CRSwNP. The aim of study isto evaluate the ability of DHMEQ to reducethe inflammatory recruiters on CRSwNP and to compare its anti-inflammatory profile as a single-agent or in association with fluticasone propionate (FP). Methods: nasal polyp fibroblasts were cultured in TNF-alpha enriched media. Cells were submitted to three different concentrations (1, 10 and 100nM) of either FP, DHMEQ or both. Inflammatory response was accessed by VCAM-1, ICAM-1 and RANTES expression (by RTQ-PCR) and protein levels by ELISA. Nuclear translocation of NF-kappa B was also evaluated. Results: both FP and DHMEQ inhibited inflammatory recruiters' production and NF-kappa B nuclear translocation. Interestingly, the anti-inflammatory effect from the association steroids plus DHMEQ was more intense than of each drug in separate. Conclusion: DHMEQ seems efficient in modulating the inflammatory process in CRSwNP. The synergic anti-inflammatory effect of DHMEQ and steroids may be a promising strategy to be explored, particularly in the setting of steroid-resistant NP. Copyright (c) 2012 S. Karger AG, Basel

Convergence of two major pathophysiologic mechanisms in nasal polyposis: immune response to Staphylococcus aureus and airway remodeling

This review is addressed two pathophysiologic mechanisms implicated in the pathogenesis of nasal polyposis: the unique remodeling process found in nasal polyp tissue and the immune response of patients with nasal polyposis to Staphylococcus aureus. These two theories converge to the same direction in different aspects, including decreased extracellular matrix production, impaired T regulation and favoring of a Th2 immune response. In patients with nasal polyposis, an exaggerated immune response to Staphylococcus aureus may aggravate the airway remodeling process.

Adult Langerhans cell histiocytosis presenting as metachronous colonic polyps

Langerhans cell histiocytosis (LCH) is a rare disease characterized by proliferation of Langerhans-type cells that express CD1a, Langerin (CD207) and S100 protein. Birbeck granules are a hallmark by ultrastructural examination. LCH presents with a wide clinical spectrum, ranging from solitary lesions of a single site (usually bone or skin) to multiple or disseminated multisystemic lesions, which can lead to severe organ dysfunction. Most cases occur in children. Gastrointestinal tract involvement is rare and has been associated with systemic illness and poor prognosis especially in children under the age of 2 years. Adult gastrointestinal LCH is very rare. We report a case of a previously healthy, nonsmoking 48-year-old male who was referred for routine screening colonoscopy. Two sessile, smooth, firm and yellowish LCH polyps measuring 0.2 cm and 0.3 cm were detected in the sigmoid colon. Fifteen months later a second colonoscopy found two histologically confirmed hyperplastic polyps at the sigmoid colon. No other LCH lesions were seen. A third colonoscopy after 28 months of follow-up found a submucosal 0.5 cm infiltrated and ulcerated LCH polyp in the cecum, close to the ostium of the appendix. The patient had been asymptomatic for all this period. Imaging investigation for systemic or multiorgan disease did not find any sign of extracolonic involvement. On histology all lesions showed typical LCH features and immunohistochemical analysis showed strong and diffuse staining for CD1a and CD207. This case illustrates two distinct clinicopathologic features not previously reported in this particular clinical setting: metachronous colonic involvement and positivity for CD207.

Paediatric traffic accident and obstructive sleep apnoea by antrochoanal polyps: case report and literature review

Antrochoanal polyps are hyperplasias of the nasal mucosa, which have their origin in the maxillary sinus and extend through the nasal cavity and the choanae into the naso- and oropharynx. In children antrochoanal polyps represent one of the more frequent manifestations of paediatric nasal polyposis. Most studies on antrochoanal polyps in children report only on nasal obstruction, hyponasal speech and snoring, which are also encountered in the most common cause of obstructive sleep apnoea syndrome; i.e. adenoid or tonsillar hyperplasia. Only very few studies report on additional health hazards by antrochoanal polyps ranging from obstructive sleep apnoea syndrome to swallowing disorders and cachexia. We present the case of an 8 year old girl with a bicycle accident caused by excessive daytime sleepiness and obstructive sleep apnoea syndrome due to an extensive antrochoanal polyp. After a transnasal polypectomy and meatotomy type II the obstructive sleep apnoea and day time sleepiness resolved completely. Awareness of this additional health hazard is important and correct evaluation and timely diagnosis of a potential antrochoanal polyp is mandatory because minimally invasive rhinosurgery is highly curative in preventing further impending problems.
