肢端黑色素瘤(AM)是黑色素瘤的一种亚型,病变分布于手掌、足底和甲床区域。不同人群AM的患病率存在差异,该亚型在白种人群中罕见,而在西班牙、非洲及亚洲人群中较为常见。研究表明,AM约占所有黑色素瘤患者的2%~3%。由于早期AM的临床诊断具有挑战性,且对早期AM缺乏认知这就导致AM患者在诊断时往往处于较晚期。因此,了解早期AM诊断的最新进展至关重要。AM与其他亚型皮肤黑色素瘤相比预后较差,对该疾病的早期认识也有助于制订治疗策略。该综述总结了AM的流行病学的特点、临床、皮肤镜和组织病理学特征,以期优化早期AM的检测策略提高患者的预后。

The incidence of dysphagia following anterior cervical discectomy and fusion (ACDF) reported in the literature varies due to differences in measures and time intervals applied, ranging from nearly 3/4 at 2 weeks to 13% at 12 months. The most commonly used dysphagia scales remain subjective, non-validated, and do not capture functional impact. Various risk factors have been identified, though few consistently reproduced and none studied in an Australasian context. The aims of this study were to use objective and validated measures, assess both traditional and novel risk factors, and determine the impact of dysphagia on dietary status, length of stay and complications. METHODS: Twenty-nine adults undergoing ACDF for degenerative pathologies were enrolled between March and November 2015 in an Australian institution. Bazaz dysphagia scale, Dysphagia short questionnaire, 3-ounce swallow test and dietary status were assessed preoperatively, and 2 days and 6 weeks postoperatively. Descriptive statistics were used to characterise the study sample and logistic regression modelling performed on risk factors. REsuLTS: Dysphagia incidence ranged from 85% on day-2 Dysphagia short questionnaire to zero on 6-week 3-ounce swallow. All measures increased at 2 days and fell by 6 weeks. Failing day-2 3-ounce swallow was the only measure associated with modifications in solids (P = 0.06), showing significant linear correlation (P = 0.02). Respiratory comorbidity increased risk of failing day-2 3-ounce swallow by more than 32-fold (OR: 32.4;95% CI: 1.8 - 587.7;P = 0.019) and scoring moderate or severe on Bazaz by almost 10-times (OR: 9.3;95% CI: 0.9 - 95.95;P = 0.061). Psychiatric history also increased risk of failing day-2 3-ounce swallow by more than 10-fold (OR: 10.9;95% CI: 1 - 123.7;P = 0.054). Failing 3-ounce swallow increased length of stay (5 versus 7 days;P = 0.013). CONCLUSIONS: Incidence of dysphagia following ACDF was dependent on the measure used, though all improved over

Mango is one of the largest commercial fruits in Myanmar and the fruit fly, B. dorsalis and B. correcta are the major pests. Mango is a kind of native fruit which can grow well as natural vegetation throughout the entire country under the various climatic conditions. We aimed to point out overuse of insecticide application in agricultural sector of Myanmar and further criteria of effective fruit fly control techniques were also proposed for worldwide ecosystem. Traditional fruit fly control is primarily focused on the uncoordinated use of insecticide applications which is orchard-by-orchard strategy. However, in view of flying distance, this localized strategy is not successful and harms the ecosystem. Occasionally, fruit bagging technique was applied by some farmers. In Myanmar’s agricultural sector, numerous varieties of cheap insecticides which mostly imported from China were plentiful. While conventional insecticide application controls were implemented annually, the population of fruit flies increased year after year, particularly in tropical region. The requirement of technical-scientific research reduced the worldwide fruit fly records. Furthermore, traditional insecticide application approach inhibits the yield and quality of mangoes that have adversely affected international trade. Importantly, in long term period of the entire previous decade, the conventional insecticide application controls make more fruit fly infestation.

目的探讨慢性精神分裂症患者外周血细胞计数水平及其与临床症状波动之间的相关性。方法纳入2022年1月于我院精神科长期住院的慢性精神分裂症患者200例。进行半年的动态随访观察,所有受试者入组后进行一次阳性与阴性症状量表(PANSS)评估临床症状及一次血常规检测后进入观察期,观察期间每2周进行一次PANSS评估、每4周进行一次血常规检测,期间若病情波动则被划分为病情波动组并终止观察、半年未波动则为未波动组,比较两组PANSS及血常规指标。结果通过观察得到病情波动组人数为86例,病情未波动组为114例;病情波动组阳性症状及兴奋评分均高于病情未波动组;病情波动组mon、WBC、NEU、LYM均高于病情未波动组,NLR、SIII均高于病情未波动组,PLT、PLR均低于病情未波动组,以上差异均无统计学意义(P> 0.05);通过比较同一患者波动期NLR、PLR、MLR值均高于同一患者稳定期。此外,波动期患者白细胞计数(WBC)、中性粒细胞(NEU)、血小板(PLT)、单核细胞计数(mon)均高于稳定期。在淋巴细胞计数方面,波动期和稳定期无显著差异。病情波动组阳性症状及兴奋评分与PLR、SIII呈正相关(P <0.05)。结论慢性精神分裂症患者阳性症状、兴奋症状波动存在炎症紊乱,WBC、NEU、SIII可作为慢性精神分裂症症状波动预测因子。

Prevalence rate of Aedes aegypti was conducted in 20 houses from semi-urban areas of Yangon Region. Larval surveys were done at indoors and outdoors water containers of five types. Prevalence rate of larval density larvae was investigated monthly by standard indices. The highest infestation rate of the container index (CI) was in June 2018 (56.52%), the second highest was in July 2017 (48.36%) and the lowest rate was in April 2017 (5.07%);those of the Jar index (JI) was highest (36.49%) in June and second highest rate (23.8%) was in October 2017. Reasoning the Metal drum (MI) was highest (13.95%) in June 2018 and second highest (6.25%) was in July 2017. The larval infestation rate of Earthen pot (EI) was highest (42.1%) in July 2017. The larval incident rate in almost all indices showed that the highest rate was at the beginning of monsoon season, in June and July, while in the remaining months, the larval incident rate was found to decrease due to the application of insecticides in the study area by the Township Public Health Department. However, the application of insecticides did not cover all the breeding sites of the mosquitoes, the water puddles under their houses were left to apply the insecticides. The positive larval incident rate was assessed by Household (HI), Container index (CI), Breteau index (BI). The highest and second highest positive larval incident rates were all in June 2018 and July 2017 in all indices, HI (27.3% and 23.4%), CI (56.52% and 48.36%), BI (17.56% and 16.79%) and SI (28.49% and 24.38%) respectively. The lowest rate in all indices was 2.56% (HI), 5.07% (IC), 2.67% (BI) and 1.91% (SI) in April. In this study, the fluctuation of indices of infestation rates and positive larval index value was positively correlated in similar trends in the study months. The reason for difficult control measure depends on the water sources under their houses and remains stagnant throughout the year, even in the dry season. High incident and death r
