Skin angiography assisted mastectomy in secondary breast angiosarcoma: Complete clinical response after neoadjuvant immunotherapy

Radiation-induced breast angiosarcoma, or secondary angiosarcoma (SAS), is a rare entity with a high risk of metastatic recurrence. Herein, we describe the use of intraoperative fluorescence-based skin angiography to guide surgical resection following a novel immunotherapy-based regimen for SAS resulting in a complete pathological response.     

Community-Based Assessment of Knowledge,Attitude, Practices and Risk Factors Regarding COVID-19 Among Pakistanis Residents During a Recent Outbreak: A Cross-Sectional Survey

Exceptional precautionary measures have been adopted to stop the transmission and control of COVID-19 through the world and Pakistan is facing lockdown in this scenario. Public loyalty to precautionary measures is affected by their knowledge, attitude, risk factors and practices (KAP) towards COVID-19. The present study was conducted among the Pakistani residents to observe the knowledge, attitude, practices and risk factors towards COVID-19 outbreak in Pakistan. A questionnaire was designed, and a cross-sectional survey was conducted among participants of the study area. Participants were asked the questions regarding knowledge, attitude, practices and risk factors towards COVID-19. Data were analyzed by SPSS and t/F test and correlation was applied among the knowledge, attitude, risk factors and practices. A total of 1060 questionnaires were received. 1004 were included while 56 were excluded. The highest representation was from Punjab province (65.6%), female (63%) and age group of 21–30 years (62.1%). Most participants were single (85%), Muslim (99.4%), Urdu speaking (45.6%) and were graduates (51.5%). Most of the participants were students (52.9%) and were from economically middle-class families (40.8%). The knowledge was positively correlated with attitude and practices whereas negatively correlated with risk factors (P?<?0.05). The attitude was negatively correlated with risk factor and positively correlated with practices. The risk factors and practices were positively correlated with each other. Health education program to improve the COVID-19 knowledge, attitude, practices and risk factors should be initiated to combat current health challenge.

     

端粒酶活性在人乳癌中的表达

目的：比较端粒酶活性在乳腺良,恶性病变中的异同,探讨其在乳癌诊断中的意义和与普遍认定的预后指标间的关系。方法：用端凿重复扩增（ＴＲＡＰ）检测了５４例乳腺癌、４４例乳腺良性病变组织的端粒酶活性。结果：５４例乳癌中４９例（９０．７４％）显示端粒酶活性,１例纤维腺瘤有弱端粒酶活性。端粒酶活性与肿瘤大小及分期有关,而与腋淋巴结转移及雌,孕激素受体之间无关。结论：端粒酶活性见于绝大多数浸润性乳癌及极少数纤维     

Multinucleated giant cells in fine-needle aspiration of thyroid nodules: their diagnostic significance.

Multinucleated giant cells (MNGCs) are reported in many thyroid lesions. This study examines whether their quantity and quality can help in the differential diagnosis. All fine-needle aspirations (FNAs) of the thyroid with a "significant" number of MNGCs were reviewed from 1995 -1998. There were 23 cases (<1% of thyroid FNAs): 8 papillary carcinomas (PC), 4 subacute thyroiditis (ST), 3 granulomas, 7 adenomatous goiters (AG), and one Hurthle-cell adenoma (HA). MNGCs with dense cytoplasm were seen exclusively in PC, ST, and granulomas. They had angulated shapes. They were most numerous, largest, and with the highest number of nuclei in ST and granulomas. MNGCs with foamy cytoplasm were seen in AG and HA and 80% of the other cases (PC, ST, and granulomas). In PC, rare MNGCs had intranuclear inclusions and grooves. The accompanying cell population was characteristic of each disease. The quantity and quality of MNGCs in thyroid FNA may be helpful in narrowing the differential diagnosis. Diagn.

Ingenane diterpenes from Euphorbia petiolata

From the whole plants of Euphorbia petiolata, four new ingenane-type diterpenoids, 3,20-O-diacetylingenol 5-O-(2' E,4' Z)-tetradecadienoate (1), 5,20-O-diacetylingenol 3- O-(2' E,4' Z)-tetradecadienoate (2), ingenol 3-O-(2' E,4' Z)-tetradecadienoate (3), and 5,20-O-isopropylidenylingenol 3-O-(2' E,4' Z)-tetradecadienoate (4) were isolated. Their structures were elucidated by spectroscopic methods and chemical transformations.     

The Sequoia circular fixator for limb lengthening

With the Sequoia fixator, lengthenings can be achieved based on the clinical facts of the case. The device is a modular apparatus that can perform corrections in several planes, and, if necessary, in a septic environment. In our opinion, a "lengthener surgeon" is one who can foresee problems and take appropriate steps to prevent them. Likewise, the surgeon must act as the coordinator of an entire team. A successful lengthening is 5% surgery and 95% postoperative nursing and physiotherapy care. In the future, a number of changes will simplify postoperative management: 1. Composite carbon rings will make the frames radiolucent and one third lighter than those made of stainless steel. Automatic tensioners will help maintain steady tension on the wires. 2. Digital analysis of the callus will provide norms of consolidation, allowing faster fixator removal and conversion to an orthosis. 3. Incorporating the foot in the frame to overcome equinus will eliminate the need for tenotomy. We believe that monolateral and ring fixators can work together in certain locations. That is why we proposed, at the 18th Societé Internationale de Chirurgie Orthopédique et Traumatologique meeting, a combined monolateral-ring construct that can be used for lengthening throughout the proximal femoral metaphysis.     

Consumer attitudes towards community pharmacy services in Saudi Arabia

Objective The purpose of this study was to determine consumer attitudes towards community pharmacy and their preferences for the introduction of new services. Methods A self‐completion questionnaire was developed and 1,144 consumers in 55 community pharmacies were invited to complete it. The questionnaire covered consumers' choice of pharmacy; their perceptions of, and actual interactions with, community pharmacists; advice from pharmacists about general health and prescribed medicines; and privacy in the pharmacy. Respondents were asked for their views about five possible new services. Setting The study was based in community pharmacies in Riyadh City, Saudi Arabia. Key findings The response rate was 79.6%. Fifty‐nine per cent of respondents often or sometimes visited a particular pharmacy. One‐quarter of respondents perceived community pharmacists as having a good balance between health and business matters, while 56.1% thought pharmacists were more concerned with the business. The majority of respondents (69.7%) said they felt comfortable asking the pharmacist for advice. Just under half (44.8%) felt that pharmacists allowed them enough time to discuss their problem fully and listened well. In addition, 58.5% of respondents indicated that their pharmacists showed sensitivity to privacy by speaking more quietly across the counter. In 14.4% of situations pharmacists were reported to use a private area within the pharmacy when discussing personal or private matters. Most respondents (65.2%) indicated that their pharmacist was willing to discuss their health problems and tried to understand their feelings. Consumers' priorities for new services were: monitoring blood pressure; measuring weight, height and temperature; monitoring blood sugar; and monitoring cholesterol. Conclusion This study showed that most pharmacy customers feel comfortable seeking advice from their pharmacist. Although many pharmacists were reported to show sensitivity to a possible lack of privacy in the pharmacy, few respondents reported that their pharmacy had a private area for discussion. Customers' views on possible new services were generally positive, with the exception of patient medication records.
