RESUMO

The incidence of ectopic pregnancies has steadily increased over recent years and despite advances in treatment it still remains a major cause of maternal morbidity and mortality. The objective of this audit was to assess whether diagnosis and management is occurring as per international suggested guidance and practice. This study is a retrospective one using data collected from June 2019 to June 2020. All data were password protected and kept anonymous. No patient contact occurred. The standard cross referenced was the 'April 2019 NICE Guideline on the Management of Ectopic Pregnancy'. Thirty-one ectopic pregnancies occurred between June 2019 and June 2020. Twenty-nine underwent surgical management and two medical. Six out of the 29 surgically managed patients were managed incorrectly. Twenty-four of the surgical cases were managed laparoscopically. Presence of a foetal heart rate remained undocumented in 21 out of 31 of cases. The results highlight the ease of access to emergency gynaecological services at Malta's national hospital. However, this audit did highlight the discrepancy that can occur in examination in association with ectopic pregnancy. An inconsistency was noted in documentation. Additionally, a number of cases could have been offered and benefitted from different modes of management.Impact StatementWhat is already known on this subject? Ectopic pregnancy (EP) is an important cause of morbidity and mortality in mothers of childbearing age. The diagnostic method and appropriate management for EP has been extensively studied. Concrete- and evidence-based guidelines guide clinical management and improve morbidity and mortality. Local guidelines improve clinical outcome.What do the results of this study add? This study shows the impact of clinical outcome without a national guideline to guide management on a national level. Malta has one national hospital in which the local obstetrics and gynaecology department is run. The results of this study thus comprise of nationwide statistics on EP and its management. Ectopic pregnancies are managed without a local guideline in place. It also reflects the ease of access to health care in smaller countries.What are the implications of these findings for clinical practice and/or further research? The findings of this study have resulted in the production of a local guideline for the management of EP, as well as the introduction of a protocol for obtaining methotrexate for medical management. It has introduced new ultrasound machines and staff training to aid diagnostics. Further re-auditing will be carried out to analyse the impact a local guideline has on clinical practice at a national level.

RESUMO

OBJECTIVE: Lymph node metastasis has been shown to represent the most significant prognostic factor in vulvar carcinoma. Because only 25% to 35% of patients with early stage disease have lymph node metastases, a significant 65% to 75% possibly do not benefit from elective inguinofemoral lymphadenectomy considering the related morbidities of wound infection, breakdown, and lower limb lymphedema. This review article aims to present and summarize the evidence available with regard to sentinel lymph node (SLN)-guided management of vulvar carcinoma. MATERIALS AND METHODS: A literature search was performed in MEDLINE resources using the subject headings "vulvar neoplasms," "sentinel lymph node," "sentinel lymph node biopsy," and "lymphatic metastasis." This search returned 886 articles that were published through January 2017. Prospective studies investigating sentinel node identification techniques and their impact on vulvar cancer management and prognosis were considered. Case reports were excluded from the review. RESULTS: Technetium-99-m-labeled nanocolloid with or without blue dye and more recently indocyanine green fluorescence have been the main techniques used for SLN identification in vulvar carcinoma. Radioisotope and near-infrared techniques have been shown to be superior to blue dye particularly with midline lesions that drain bilaterally or that drain directly to a deep pelvic node. Patients with a small unifocal primary tumor (<4 cm) and no obvious preoperative metastasis have been shown to have low groin recurrence rates and excellent disease-specific survival rates with minimal treatment-related morbidity when undergoing SLN biopsy-guided management. CONCLUSIONS: Sentinel lymph node biopsy-guided management seems to be safe when restricted to International Federation of Gynecology and Obstetrics IB to II cases where tumors are unifocal, less than 4 cm in size, and when there is no evidence of lymph node metastasis on clinical/radiological assessment. This reduces operative morbidity in this cohort of patients.

RESUMO

There appears to be a connection between COVID-19 infection and an airborne microscopic pollutant called particulate matter which has been suggested to act as vector for viral transmission. The highest human exposure to particulate matter occurs during smoking and to a lesser extent applies to 2nd hand smoking.  This article offers a hypothetical proposition that particulate matter derived from tobacco smoking may act as COVID-19's vector for infection transmission. With a background smoking Chinese male population of more than 66% and more than 70% of Chinese nonsmokers exposed to 2nd hand smoke the potential of exhaled smoke acting as a viral vector is significant.  If this hypothesis is proven, measures such as face protection to reduce coronavirus-laden particulate matter transmission, measures of social distancing and legislation to protect nonsmokers from contracting the infection through 2nd hand smoking should be implemented.

RESUMO

More than 50% of all gynecologic tumors can be classified as rare (defined as an incidence of ≤6 per 100,000 women) and usually have a poor prognosis owing to delayed diagnosis and treatment. In contrast to almost all other common solid tumors, the treatment of rare gynecologic tumors (RGT) is often based on expert opinion, retrospective studies, or extrapolation from other tumor sites with similar histology, leading to difficulty in developing guidelines for clinical practice. Currently, gynecologic cancer research, due to distinct scientific and technological challenges, is lagging behind. Moreover, the overall efforts for addressing these challenges are fragmented across different European countries and indeed, worldwide. The GYNOCARE, COST Action CA18117 (European Network for Gynecological Rare Cancer Research) programme aims to address these challenges through the creation of a unique network between key stakeholders covering distinct domains from concept to cure: basic research on RGT, biobanking, bridging with industry, and setting up the legal and regulatory requirements for international innovative clinical trials. On this basis, members of this COST Action, (Working Group 1, "Basic and Translational Research on Rare Gynecological Cancer") have decided to focus their future efforts on the development of new approaches to improve the diagnosis and treatment of RGT. Here, we provide a brief overview of the current state-of-the-art and describe the goals of this COST Action and its future challenges with the aim to stimulate discussion and promote synergy across scientists engaged in the fight against this rare cancer worldwide.

RESUMO

Mesenchymal Stem Cells (MSCs) are widely used in therapeutic applications. Their plasticity and predisposition to differentiate into a variety of cell types, including those of the neuronal lineage, makes them ideal to study whether a selection of miRNAs may direct the differentiation of MSCs into neuroblasts or neuroblastoma to mature neurons. Following a short-listing, miR-107, 124 and 381 were selected as the most promising candidates for this differentiation. MSCs differentiated into cells of the neural lineage (Conditioned Cells) upon addition of conditioned medium (rich in microvesicles containing miRNAs) obtained from cultured SH-SY5Y neuroblastoma cells. Characterisation of stemness (including SOX2, OCT4, Nanog and HCG) and neural markers (including Nestin, MASH1, TUBB3 and NeuN1) provided insight regarding the neuronal state of each cell type. This was followed by transfection of the three miRNA antagonists and mimics, and quantification of their respective target genes. MiRNA target gene expression following transfection of MSCs with miRNA inhibitors and mimics demonstrated that these three miRNAs were not sufficient to induce differentiation. In conditioned cells the marginal changes in the miRNA target expression levels reflected potential for the modulation of intermediate neural progenitors and immature neuron cell types. Transfection of various combinations of miRNA inhibitors and/or mimics revealed more promise. Undoubtedly, a mix of biomolecules is being released by the SH-SY5Y in culture that induce MSCs to differentiate. Screening for those biomolecules acting synergistically with specific miRNAs will allow further combinatorial testing to elucidate the role of miRNA modulation.

RESUMO

The skin is one of the largest organs of the body, which is significantly affected by the aging process and menopause. The significant changes sustained by the skin during the menopause are due to the effect sustained on the skin's individual components. The estrogen receptor has been detected on the cellular components of the skin. Accordingly, dermal cellular metabolism is influenced by the hypoestrogenoemic state of menopause leading to changes in the collagen content, alterations in the concentration of glycoaminoglycans and most importantly the water content. Consequently changes in these basic components leads to an alteration in function compatible with skin aging. Changes in the skin collagen leads to diminished elasticity and skin strength. Collagen content may be measured by various methods such as direct skin biopsy, skin blister assessment for collagen markers and skin thickness measurement. All these variables indicate a reduction in collagen content following menopause. This may be reversed with the administration of estrogen given both topically and systemically.A reduction in hydrophilic glycoaminglycans leads to a direct reduction in water content, which influences the skin turgor. These effects on glycoaminoglycans, due to the hypoestrogenia, have been clearly shown in animal studies and appeared to be rapidly reversed with the application of estrogens. The sum total of these basic effects on the skin leads to wrinkles, the skin condition typifying skin aging.Structures resident in the skin are likewise influenced by menopause. Changes to the cutaneous vascular reactivity are noted following menopause. Capillary blood flow velocity decreases significantly in postmenopausal women. Postmenopausal flushing is due to profound vasodilatation in the dermal papillae. Hair growth is also influenced by the hormonal milieu and consequently hair loss has been associated with the beginning of menopause. Treatments administered for menopause, in particular hormone replacement therapy, appear to alter its effects on the basic components of the skin as well as the more complex structures residing in the skin, consequently retarding the skin aging process.
