Association between habitual snoring,middle ear disease,and speech problems in young children with non-syndromic cleft palate anomalies

The purpose of this study was to investigate the association between habitual snoring (HS), middle ear disease (MED), and speech problems in children with cleft palate. This cross-sectional study included children aged 2.0–7.9 years with non-syndromic cleft palate anomalies. Parents completed the Pediatric Sleep Questionnaire and a questionnaire about MED. Audiograms and speech assessment were also conducted. Ninety-five children were enrolled; 15.2% of families reported HS, 97.6% MED, and 17.1% speech problems. HS (37.5% vs 10.3%, P = 0.007) and early episodes of MED (92.3% vs 58.2%, P = 0.021) were more likely to be reported for children with isolated cleft palate when compared to those with cleft lip and palate. Children with cleft lip and palate had a higher frequency of MED with effusion compared to those with Robin sequence (86.4% vs 57.1%, P = 0.049). The odds ratio for HS in children with ≥1 episode of MED in the last year was 7.37 (95% confidence interval 1.55–35.15, P = 0.012). There was a trend for children with speech problems reported by parents to have HS (30.8% vs 11.5%, P= 0.076). Anatomical factors play a role in the frequency of upper airway symptoms in children with cleft palate. A recent history of at least one episode of MED was associated with an increased frequency of HS.     

Association between dysglycemia and the Charlson Comorbidity Index among hospitalized patients with diabetes

AimInpatient dysglycemia has been linked to short-term mortality, but longer-term mortality data are lacking. Our aim was to evaluate the association between inpatient dysglycemia and one-year mortality risk.MethodsRetrospective chart review of adults with diabetes hospitalized between 2015 and 2019. The Charlson Comorbidity Index (CCI) was used to estimate 1-year mortality risk, stratified into low (CCI ≤ 5) and high risk (CCI ≥6). Simple and multivariable logistic regression was used to evaluate the association between dysglycemic measures and high mortality risk.ResultsAmong 22,639 unique admissions, BG ≥ 180, ≥300, ≤70, <54 and <40 mg/dL were associated with adjusted odds of 1.43 (95 % CI, 1.33, 1.54), 1.58 (95 % CI, 1.48, 1.68), 2.16 (95 % CI, 2.01, 2.32), 2.58 (95 % CI, 2.32, 2.86), and 2.56 (95 % CI, 2.19, 2.99) for high mortality risk, respectively. Older age and Black race were positively associated with hyperglycemia and hypoglycemia. Myocardial infarction, congestive heart failure (CHF), and moderate to severe liver disease were most strongly associated with hyperglycemia, while renal disease, CHF, peripheral vascular disease, and peptic ulcer disease were most strongly associated with hypoglycemia.ConclusionsInpatient hypoglycemia and hyperglycemia were both positively associated with higher one-year mortality risk, with stronger magnitude of association observed for hypoglycemia. The association appears to be mediated mainly by presence of diabetes-related complications.     

Necrotising myositis – learnings for a plastic surgeon

BackgroundNecrotising myositis (NM) is a life-threatening emergency. Prompt treatment is associated with more favourable outcomes, but early diagnosis is challenging. The initial absence of cutaneous signs and symptoms coupled with delayed recognition commonly result in higher rates of morbidity and mortality.ObjectivesAnalyse data regarding demographics, epidemiology, aetiology, clinical manifestations, diagnosis and treatment of previously reported cases. This publication is intended for plastic surgeons in training to help them look out for this disease.Search methods/criteriaPublications reporting necrotising myositis between 1974 to January 2020 were identified from Embase, Medline All, Web of Science Core Collection, Google Scholar and Cochrane Central Register of Controlled Trial.Data collection and analysis: Identified studies were exported to an end note library. In animal studies, studies relating to statin-induced myotoxicity and auto-immune myositis were excluded. The quality of included case reports was assessed using JBI Critical Appraisal Checklist for Case Reports.Main resultsThe most common initial presentation was a few days of antecedent prodromal flu-like symptoms associated with muscle pain. The mean age was 43.3 years and 82% had no significant medical history. The most frequent misdiagnoses were muscle strain (11%), deep vein thrombosis (10%) and viral illness (9%). Seventy-four per cent of presentations were due to Group A Streptococcus infections and only 3.5% of cases were polymicrobial. The most common clinical course following the initial presentation was rapid deterioration into profound sepsis and progression into multi-organ failure. The overall mortality rate was 36.5%.ConclusionsNM is a life-threatening muscle infection. It is a diagnostic conundrum as initial presentation is often only myalgia without features of preceding trauma. We propose that a high index of suspicion and increased awareness will reduce morbidity.OtherPROSPERO (registration number CRD42018087060). Nil funding/conflict of interest.     

Role of arterial stiffness and endothelial dysfunction on lower limb performance in older adults with type 2 diabetes: A cross-sectional study

AimTo verify whether arterial stiffness and endothelial dysfunction influence lower limb muscle strength and gait speed in older adults with type 2 diabetes mellitus (T2DM).MethodsCross-sectional study including seventy-eight older adults with T2DM (aged 67 ± 6 years and 42 % male). Arterial stiffness was assessed using pulse wave velocity (PWV), while endothelial function was measured by flow-mediated dilation (FMD). Lower limb muscle strength and gait speed were assessed using the 30-second chair stand test (30s-CST) and 10-Meter Walk Test, respectively.ResultsBoth PWV (m/s) and FMD (%) were univariately associated with number of repetitions in 30s-CST and gait speed (P < 0.05). After control for age, sex and body mass index, PWV remained associated with repetitions in 30s-CST (95 % CI: ?0.494 to ?0.054; P = 0.015) and gait speed (95 % CI: ?0.039 to ?0.002; P = 0.031). After adjustments for control variables, T2DM duration and glycemic control, FMD was associated with repetitions in 30s-CST (95 % CI: 0.008 to 0.324; P = 0.039) and gait speed (95 % CI: 0.011 to 0.038; P = 0.001).ConclusionIn older adults with T2DM, both arterial stiffness and endothelial dysfunction are associated with decreased leg muscle strength and slower gait speed.

静吸复合麻醉对特重度烧伤患者凝血功能障碍的影响

目的收集特重度烧伤(总TBSA50%以上或三度TBSA20%以上或伴有严重并发症者)患者围术期凝血指标(APTT、PT、FIB、DD和PLT)，分析静吸复合麻醉对患者凝血功能的影响及其临床意义。 方法选取近3年内蒙古医科大学第三附属医院烧伤外科收治的特重度烧伤患者148例，根据入院14 d内的预后分为死亡组和生存组，生存组男性129例，女性9例；年龄24~59岁，平均(43.30±12.90)岁。死亡组男性8例，女性2例；年龄26~63岁，平均(46.19±15.41)岁。收集入院时(T0)，术前(早晨入手术室前，T1)，术毕(送至PACU未拔除气管导管前，T2)及术后2 d(T3)4个时间点的凝血指标，比较两组凝血指标动态差异。 结果死亡组休克期输液量、累计血浆、红细胞输入量显著高于生存组(P<0.01)。T0时，生存组的FIB(1.78±0.32)显著高于死亡组(1.26±0.07)(P<0.05)；T2时，两组APTT、PT均显著缩短(P<0.05)，生存组的FIB(3.86±0.40)显著高于死亡组(2.45±1.02)(P<0.05)；T3时，死亡组PLT显著低于生存组(P<0.01)。 结论特重度烧伤患者在围手术期易出现高凝状态，并且这可能导致患者死亡。静吸复合麻醉和围术期大量液体复苏会促进患者的高凝状态。
