Physical properties of peat are widely applied to detect the quality of peatland ecosystem. A comprehensive dataset on the peat properties is the foundation for the development tool and model of peat ecosystem, especially in region with frequent wildfire. Here we established a tabular dataset for physical properties of lowland tropical peatland in Indonesia.

No Correlation Exists Between Tibial- and Femoral-Based Measurements of Patella Alta in a Population With Chronic Patellofemoral Pain or Instability Undergoing Patella Distalization.

Purpose: To investigate whether the patellotrochlear index (PTI) predicts patella alta as determined by tibial-based methods of Insall-Salvati (IS) and Caton-Deschamp (CDI) indexes in a pathological population (with patellofemoral pain and/or instability), in addition to determining whether PTI and sagittal patellofemoral engagement (SPE) correlate with trochlea length as determined by lateral condyle index (LCI).

Methods: Patients with confirmed patella alta (IS/CDI ratio >1.2) undergoing tibial tubercle osteotomy for patellofemoral pain/instability with an available magnetic resonance imaging (MRI) scans were included.

Midterm outcome of superior capsular reconstruction using doubled acellular human dermal allograft for irreparable rotator cuff tear.

Background: Thicker (folded) facia lata autografts have been shown to be superior to thinner grafts and single-layered acellular human dermal (HD) allografts for superior capsular reconstruction (SCR) in biomechanical studies. The aim of this study was to evaluate the midterm clinical outcomes following SCR for irreparable supraspinatus tears using doubled (folded) HD allograft.

Methods: Thirty-two patients who had undergone SCR using doubled HD allograft between February 2012 and January 2020 were recruited in a continuous manner in this retrospective study.

The effects of social evaluation and looming threat on self-attentional biases and social anxiety.

This paper examines how two proposed cognitive vulnerabilities of social anxiety, the fear of negative evaluation, and looming cognitive style may combine with socially demanding situations in predicting social anxiety symptoms and performance deficits. Fifty-two individuals previously identified as possessing these two cognitive vulnerabilities were randomly assigned to conditions in a 2 (high versus low social evaluation)x2 (high versus low temporal looming) experimental design. Significant interaction effects were found for: (a) residual change in anxiety symptoms from baseline level, and (b) performance on a speech task.

Releasable adjustable suture technique for children.

Purpose: Residual esotropia is a problem for children with esotropia that can follow bilateral medial rectus recession, and the use of adjustable sutures is nearly impossible. The aim of this work is to describe a new suture technique to overcome this problem.

Methods: Medial rectus muscle was recessed and secured to the sclera at the predetermined recession position after suspending it 1.

Methods: Forty adult patients aged 16 to 46 years (median, 24 years) underwent adjustable rectus muscle surgery under topical lidocaine jelly 2% and intravenous 10 mg nalbuphine given 10 minutes before surgery.

Outcomes with changes in prescribing of glycoprotein IIb/IIIa inhibitors in PCI.

Background: Glycoprotein IIb/IIIa receptor antagonists have been shown to have an impact on the outcomes of death/myocardial infarction (MI) in patients undergoing percutaneous coronary intervention. At our institution, tirofiban has largely replaced abciximab in an attempt to decrease costs.

Objective: To assess the impact of this change on patient outcomes in the absence of head-to-head trials.

Outcome predictors of ultrafiltration in patients with refractory congestive heart failure and renal failure.

This study is an attempt to identify predictors of outcome from the use of ultrafiltration (UF) in patients with refractory congestive heart failure (CHF) and renal failure. The authors studied 30 patients in NYHA functional class IV in whom UF was utilized in the management of refractory CHF. Patients were retrospectively divided into two groups according to their outcome.

Critical role of pulmonary angiography in the diagnosis of pulmonary emboli following cardiac surgery.

This study was conducted to identify patients at high risk of the development of Pulmonary Embolism (PE) after open heart surgery, to evaluate pertinent diagnostic methods, and to assess the mortality associated with this complication. We evaluated the records of 2,551 consecutive patients who underwent open heart surgery over a 10-year period to identify those patients in whom PE developed. All surgical reports, ventilation/perfusion scans, pulmonary angiograms, and autopsies from the same period were also reviewed.

Recanalization characteristics of intracoronary streptokinase compared to intravenous tissue plasminogen activator following acute myocardial infarction: a community hospital experience.

This study compares the recanalization characteristics of intracoronary streptokinase (IC-SK) with those of intravenous tissue plasminogen activator (t-PA) in patients with acute myocardial infarction (AMI) treated in the first 6 hours after onset of symptoms. We studied 263 patients with AMI. Among these, 160 were treated with IC-SK; in 59 the drug was given within the first 3 hours and in 101 from 3 to 6 hours.

The potential impact of the thrombolytic era on cardiac rupture complicating acute myocardial infarction.

Cardiac rupture complicating acute myocardial infarction (AMI) remains a serious diagnostic and therapeutic challenge. The authors present 27 consecutive patients who died from cardiac rupture following AMI. These included 22 patients from 1975 through 1983 (prethrombolytic era) and 5 patients from 1984 through 1992 (postthrombolytic era) and all had postmortem examination.

Sustained supraventricular tachyarrhythmias following coronary artery bypass surgery comparing mammary versus saphenous vein grafts.

This retrospective study was designed to determine the incidence of sustained supraventricular tachyarrhythmias (SVTs) in patients undergoing coronary artery bypass grafting (CABG) with internal mammary artery (IMA) grafts, Group A, compared with those with saphenous vein grafts (SVG), Group B. Among 569 consecutive patients who underwent CABG surgery in the same institution, a total of 80 cases from Group A and 80 cases from Group B were selected for this study after application of exclusion criteria. Excluded from this study were the following: patients with preexisting or prior history of SVTs, significant left ventricular dysfunction (ejection fraction less than 40%), postoperative myocardial infarction, drug toxicity or electrolyte imbalance, and advanced chronic obstructive lung disease.

Acute dissecting aortic aneurysm: community hospital experience in 20 cases.

Of 20 patients with dissecting aortic aneurysm managed at our community hospital, 16 had type A (ascending) dissection and four had type B (descending) dissection. Twelve of the patients with type A dissection were operated on; six of them survived and six died postoperatively. The remaining four patients with type A dissection had cardiopulmonary arrest and died before surgical intervention was attempted.

Total inferior vena cava thrombosis following coronary artery bypass surgery.

A 44-yr-old male presented with abdominal and back pain following coronary bypass surgery (CABG). Total inferior vena cava (IVC) thrombosis was then documented by computed tomography as well as IVC contrast cineangiography. Furthermore, the patient developed multiple pulmonary emboli.

Early percutaneous transluminal coronary angioplasty or coronary bypass surgery following thrombolytic treatment of acute myocardial infarction.

Coronary reocclusion rates following intracoronary streptokinase (IC-SK) infusion remain significantly high despite anticoagulation. Early intervention by coronary angioplasty (PTCA) or coronary bypass surgery (CABG) was advocated to minimize such risk and/or maintain coronary reperfusion. Of 71 consecutive patients (60 men, 11 women; mean age, 54.

Observer variation in the echocardiographic diagnosis of mitral valve prolapse.

To assess inter- and intraobserver variation in the echocardiographic diagnosis of mitral valve prolapse, three independent observers analyzed M-mode echocardiograms (n = 80) and two-dimensional echocardiograms (n = 65) of patients with a mobile midsystolic click with or without a late or holosystolic murmur. In addition, a control group of 100 normal echocardiograms were interspersed among the echocardiograms of patients with mitral valve prolapse and were then interpreted. Each of the three observers analyzed all M-mode and two-dimensional echocardiograms initially and then 2 weeks later for the presence or absence of mitral valve prolapse.

Acute myocardial infarction with "normal" coronary arteries: clinical and angiographic profiles, with ergonovine testing.

Among 528 patients consecutively undergoing selective coronary angiography after acute myocardial infarction, ten cases (1.9%) with angiographically normal coronary arteries were identified. Eight of these ten patients were 45 years of age or younger and comprised 11% of those studied in this age group, with higher prevalence in females (five of 18 [28%]) versus males, (three of 57 [5%]).

Ventricularization of right atrial wave form in amyloid restrictive cardiomyopathy.

Two patients with biopsy-proven amyloid restrictive cardiomyopathy were presented. Both cases showed ventricularization of an elevated right atrial pressure wave form in absence of tricuspid regurgitation. Possible explanations for this finding as well as its clinical implications are discussed.

Incidence of new focal pulmonary emboli after routine cardiac catheterization comparing the brachial to the femoral approach.

The incidence of pulmonary perfusion defects after routine cardiac catheterization was assessed in 56 patients by comparing ventilation-perfusion (V/Q) lung scans obtained before and 1 day after catheterization. Patients were prospectively randomized in two groups, one in which the brachial approach was performed using an antecubital cutdown procedure, and one in which the percutaneous femoral approach was used. None of the patients with the brachial approach had any ventilation-perfusion mismatch on the V/Q scan; however, three patients (8.

Increased left ventricular mass in idiopathic mitral valve prolapse.

We performed M-mode echocardiography on 100 subjects with idiopathic mitral valve prolapse (IMVP) and on 100 normal control subjects to determine if differences exist between the two groups in cardiac chamber size, left ventricular performance or left ventricular mass. Subjects with IMVP demonstrated significantly greater left ventricular mass than normal control subjects. There were no significant differences in fractional shortening of the left ventricle or left ventricular end-diastolic volume.

Sensitivity and specificity of M mode echocardiographic signs of mitral valve prolapse.

To assess the sensitivity and specificity of previously described M mode echocardiographic signs of mitral valve prolapse, 100 subjects with a mobile mid systolic click and 100 matched normal control subjects were prospectively studied. Late systolic posterior motion and holosystolic hammocking of the mitral leaflets were common, highly specific signs of mitral valve prolapse. When these signs were combined as a single criterion, sensitivity was 85 percent and specificity was 99 percent.
