附着龈重建应用于口腔种植修复中的临床效果观察

目的探讨附着龈重建应用于口腔种植修复中的临床效果。方法将本院于2016年10月-2018年10月期间收治的行口腔种植修复治疗的附着龈缺失患者82例作为研究资料,依据治疗方案分组,对照组为传统修复治疗方案,观察组采用附着龈重建治疗修复方案,各41例,评价两组术后不同阶段附着龈宽度、龈缘外形及附着点重建改善效果,并评价患者评价治疗满意度。结果术后3个月观察组患者附着龈宽度改善Ⅲ级率56.10%明显高于对照组0.00%,龈缘外形与附着点重建Ⅲ级率60.98%明显高于对照组0.00%(P <0.05);术后6个月观察组患者附着龈宽度改善Ⅲ级率75.61%明显高于对照组0.00%,龈缘外形与附着点重建Ⅲ级率73.17%明显高于对照组0.00%(P <0.05);观察组治疗满意度97.56%与对照组70.73%比较明显更高(P <0.05)。结论针对行口腔种植修复治疗的附着龈缺失患者采用附着龈重建治疗修复方案利于快速恢复附着龈增加宽度,改善龈缘外形及附着点重建效果,获得患者的高度满意度,治疗价值较高。     

2015—2017年解放军总医院抗震颤麻痹药物的使用情况分析

目的 了解解放军总医院抗震颤麻痹药物的应用情况与用药趋势。方法 采用世界卫生组织（WHO）推荐的以限定日剂量（DDD）为指标的分析方法，对2015-2017年解放军总医院抗震颤麻痹药物的销售金额、用药频度（DDDs）、日均费用（DDC）及排序比（B/A）等进行统计分析。结果 普拉克索、多巴丝肼和恩他卡朋的用药金额始终处于前3位，普拉克索的用药金额逐渐上升，卡比多巴/左旋多巴的用药金额逐渐下降；DDDs排序列前2位的是多巴丝肼和司来吉兰，多巴丝肼的DDDs逐年上升，一直处于第1位；2015-2016年各种抗震颤麻痹药物的DDC较为稳定，2016-2017年各种抗震颤麻痹药物的DDC开始略有下降；除普拉克索和恩他卡朋的B/A始终小于1.00，其他抗震颤麻痹药物的B/A均在1.00以上波动。结论 解放军总医院抗震颤麻痹药物的使用较为合理，其中多巴丝肼、普拉克索和司来吉兰具有很好的市场前景。     

Novel β-Coronavirus (SARS-CoV-2): Current and future aspects of pharmacological treatments

The novel coronavirus outbreak has reported to be rapidly spreading across the countries and becomes a foremost community health alarm. At present, no vaccine or specific drug is on hand for the treatment of this infectious disease. This review investigates the drugs, which are being evaluated and found to be effective against nCOVID-19 infection. A thorough literature search was performedon the recently published research papers in between January 2020 to May 2020, through various databases like “Science Direct”, “Google Scholar”, “PubMed”,“Medline”, “Web of Science”, and “World Health Organization (WHO)”. We reviewed and documented the information related with the current and future aspects for the management and cure of COVID-19. As of 21st July 2020 a total of 14,562,550 confirmed cases of coronavirus and 607,781 deaths have been reported world-wide. The main clinical feature of COVID-19 ranges from asymptomatic disease to mild lower respiratory tract illness to severe pneumonia, acute lung injury, acute respiratory distress syndrome (ARDS), multiple organ dysfunction, and death. The drugs at present used in COVID-19 patients and ongoing clinical trials focusing on drug repurposing of various therapeutic classes of drug e.g. antiviral, anti-inflammatory and/or immunomodulatory drugs along with adjuvant/supportive care. Many drugs on clinical trials shows effective results on preliminary scale and now used currently in patients. Adjuvant/supportive care therapy are used in patients to get the best results in order to minimize the short and long-term complications. However, further studies and clinical trials are needed on large scale of population to reach any firm conclusion in terms of its efficacy and safety.     

A Reminder of Methylene Blue's Effectiveness in Treating Vasoplegic Syndrome after On-Pump Cardiac Surgery

The inflammatory response induced by cardiopulmonary bypass decreases vascular tone, which in turn can lead to vasoplegic syndrome. Indeed the hypotension consequent to on-pump cardiac surgery often necessitates vasopressor and intravenous fluid support. Methylene blue counteracts vasoplegic syndrome by inhibiting the formation of nitric oxide.We report the use of methylene blue in a 75-year-old man who developed vasoplegic syndrome after cardiac surgery. After the administration of methylene blue, his hypotension improved to the extent that he could be weaned from vasopressors. The use of methylene blue should be considered in patients who develop hypotension refractory to standard treatment after cardiac surgery.     

Pharmacodynamics of combined estrogen–progestin oral contraceptives: 4. Effects on uterine and cervical epithelia

ABSTRACT

Introduction: Steroid hormones are responsible for specific changes in the endometrium during the menstrual cycle, when they are sequentially secreted and, because of this, in the early days sequential combined oral contraceptive regimens were utilized. The same basic concept has been utilized with multi-phasic regimens, in order to produce endometrial pictures mimicking the normal cycle.

Areas covered: The Endometrial effects of progestins and estrogens; combined monophasic high- (50 μg), medium- (30 μg), low- (20 μg), ultralow- (15 μg) estrogen content; sequential regimens; multiphasic combinations; treatment schedules.

Cervical effects of combined high-dose and sequential combinations, including evidence for an increase in malignant lesions.

Expert opinion: Overall, combined oral contraceptives (COCs) inhibit normal proliferative changes and the endometrium becomes thin, narrow, with widely spaced glands and pre-decidual changes in the stroma. During the first few cycles the progestin induces a coexistence of proliferative and secretory features; with time, the picture changes because the progestin induces a down-regulation of estrogen receptors, resulting in tortuous glands similar to those in the secretory phase, but characterized by a quiescent, atrophic glandular epithelium.

In the cervical epithelium, under the influence of high-dose COCs, endocervical glands became hypersecretory and in some instances, distinctive type of atypical polypoid endocervical hyperplasia is found.
