床旁多普勒超声引导下经皮气管切开术在重症脑出血患者中的应用

目的探讨床旁多普勒超声引导下经皮气管切开术（PDT）在重症脑出血患者中的应用价值。方法选取2014年1月—2019年4月南方医科大学附属小榄医院重症医学科监护治疗的重症脑出血患者126例，在ICU床旁采用超声引导下行PDT。术前采用超声进行检查，明确气管位置、周围组织及血管情况，确定穿刺部位及深度，指导术前气管导管退管。术中实时超声引导，确保手术安全。术后超声确认气管切开套管位置，筛查排除气胸等相关并发症。观察操作时间（从皮肤穿刺到成功置入气管套管时间）、一针穿刺成功率、置管成功率、气管插管意外脱管率；观察术中及术后并发症：出血量、血管/甲状腺损伤、气管后壁损伤、皮下气肿、气胸、低氧血症发生率等。结果126例患者手术均一次操作成功，一针穿刺成功率及置管成功率均为100%，未发生气管插管意外脱管。操作时间5~12 min，平均操作时间7.5 min。术中及术后未发生难以控制的大出血、严重低氧血症、血管/甲状腺损伤、气管后壁损伤、皮下气肿及气胸等并发症。结论对重症脑出血患者行床旁实时超声引导下行PDT，提高了手术的可视性、操作性和安全性，提高PDT成功率，降低相关并发症，具有良好的临床价值。     

老年轻度认知障碍患者血清瘦素、甲状腺激素水平与局部脑血流量关系的研究

Elevación del lactato en el postoperatorio como marcador de isquemia mesentérica aguda. Descripción de dos casos

Serum lactate is a non-specific marker of tissue hypoperfusion. Elevated serum lactate is used in the differential diagnosis of acute intestinal ischemia. Although this practice is controversial, in the absence of other validated markers lactate is still used because of its high sensitivity.We present the cases of two patients who developed acute mesenteric ischemia as a post-surgical complication. The patients reported moderate abdominal pain —a non-specific symptom in the postoperative context— and tests showed progressively increasing serum lactate levels, which facilitated suspicion and subsequent diagnostic confirmation through an imaging test.These cases highlight the physiopathological importance of lactate elevation in the perioperative context and of performing a differential diagnosis of its possible causes, including mesenteric ischemia. Although the outcome was negative in the first case, early suspicion allowed us to make an effective diagnosis and administer appropriate treatment in the second patient.     

Salvage Focal Cryotherapy Offers Similar Short-term Oncologic Control and Improved Urinary Function Compared With Salvage Whole Gland Cryotherapy for Radiation-resistant or Recurrent Prostate Cancer

BackgroundWe compared the short-term oncologic and functional outcomes of salvage focal cryotherapy (SFC) with those of salvage total cryotherapy (STC) for radiotherapy (RT)-persistent/recurrent prostate cancer.Materials and MethodsWe queried the Cryo On-Line Database registry for men who had undergone SFC and STC of the prostate for RT-persistent or recurrent disease. Propensity score weighting was used to match age at treatment, presalvage therapy prostate-specific antigen level, Gleason sum, and presalvage cryotherapy androgen deprivation therapy status. The primary outcome was progression-free survival.ResultsA total of 385 men with biopsy-proven persistent or recurrent prostate cancer after primary RT were included in the present study. The median follow-up, age, prostate-specific antigen, and Gleason sum before salvage cryotherapy was 24.4 months (first and third quartile, 9.8 and 60.3), 70 years (first and third quartile, 66 and 74 years), 4 ng/dL (first and third quartile, 2.7 and 5.6 ng/dL), and 7 (first and third quartile, 6 and 8), respectively. After propensity score weighting, the difference in progression-free survival was not statistically significant between the patients who had undergone STC and those who had undergone SFC (79.8% vs. 76.98%; P = .11 on weighted log-rank test). SFC was associated with a lower probability of post-treatment transient urinary retention (5.6% vs. 22.4%; P < .001). No significant differences were found in the incidence of rectal fistula (1.4% vs. 3.8; P = .30), new-onset urinary incontinence within 12 months (9.3% vs. 15.1%; P = .19), or new-onset erectile dysfunction within 12 months (52.6% vs. 59.6%; P = .47) between the SFC and STC groups, respectively.ConclusionsSTC resulted in similar 2-year oncologic outcomes compared with SFC in the RT-persistent/recurrent disease population. However, the patients who had undergone SFC had a lower urinary retention rate compared with those who had undergone STC.

进展型脑梗死患者miRNA的表达水平及临床意义

目的探讨进展型脑梗死患者微小RNA(miRNA)的表达水平及临床意义。方法回顾性分析2016年7月至2018年7月期间我院收治的138例脑梗死患者病例资料。根据斯堪的那维亚卒中量表(SSS)将其分为对照组(稳定型脑梗死,82例)和观察组(进展型脑梗死,56例)。观察组患者按照高级中枢损伤严重程度评定标准(MESSS)评分为轻度进展(30例)、中度进展(17例)、重度进展(9例)三个亚组。对观察组出院两个月后进行预后随访,并将其分为预后不良组及预后良好组。分析进展型脑梗死患者miRNA的表达水平及临床意义。结果进展型脑梗死患者的miRNA-21、miRNA-223水平均显著高于稳定型脑梗死患者(P 0. 05); miRNA-21、miRNA-223的高表达均是进展型脑梗死的危险因素(P 0. 05),且进展型脑梗死的严重程度与血清miRNA-21、miRNA-223的表达水平均呈正相关(r=0. 834,P=0. 008;r=0. 896,P=0. 001)。预后不良组患者血清miRNA-21、miRNA-223表达水平显著高于预后良好组(P 0. 05);血清miRNA-21、miRNA-223表达水平预测进展型脑梗死预后的AUC面积分别为0. 805、0. 834,并分别得出截断值4. 45 (敏感度77. 14%,特异性82. 28%)、7. 06(敏感度82. 86%,特异性73. 42%)。结论进展型脑梗死患者miRNA-21、miRNA-223呈高表达,且其表达水平与脑梗死严重程度呈正相关,同时对预测进展型脑梗死预后均具有较高的敏感度和特异度,有可能成为一种早期诊断和预测进展型脑梗死生物标志物。     

A 4‐year follow‐up case of extrusive luxation in a patient with cerebral palsy

Cerebral palsy (CP) is a condition caused by brain damage before, during, or shortly after birth. Communication can be a challenge when treating patients with CP. Some patients can communicate verbally, while others use augmentative alternative communication tools or have individualized means of communication. Therefore, professional dental treatment in individuals with CP is challenging, especially if the patient is affected by dental trauma and requires emergency treatment. This report shows how individualized communication skills assessment allowed us to successfully manage a 9‐year‐old patient with CP, who suffered extrusive luxation of the permanent lower incisor. In the present case, the teeth were repositioned briefly after the trauma had occurred and then stabilized with a flexible splint according to international guidelines. The teeth remained vital and periodontal repair was observed during the 4‐year follow‐up.     

Clinical outcomes of bypass-first versus endovascular-first strategy in patients with chronic limb-threatening ischemia due to infrageniculate arterial disease

Background

Chronic limb-threatening ischemia (CLTI), defined as ischemic rest pain or tissue loss secondary to arterial insufficiency, is caused by multilevel arterial disease with frequent, severe infrageniculate disease. The rise in CLTI is in part the result of increasing worldwide prevalence of diabetes, renal insufficiency, and advanced aging of the population. The aim of this study was to compare a bypass-first with an endovascular-first revascularization strategy in patients with CLTI due to infrageniculate arterial disease.
