Precision of Magnetic Resonance Imaging in Detection of Anterior Cruciate Ligament and Posterior Cruciate Ligament Ruptures and Subsequent Arthroscopic Correlations: An Investigation.

 The present study endeavors to scrutinize the precision of magnetic resonance imaging as a diagnostic modality for detecting ligament disruption of the knee, with arthroscopy serving as the gold standard. The study delves into the sensitivity, specificity, positive predictive value, and negative predictive value of magnetic resonance imaging (MRI) results in a cohort of 200 patients against diagnostic arthroscopy.  Our institution conducted a comprehensive clinical examination of all patients with knee injuries, and those with affirmative findings suggestive of ligament disruption were subjected to an MRI scan.

Development of a biodegradable microfluidic paper-based device for blood-plasma separation integrated with non-enzymatic electrochemical detection of ascorbic acid.

In the present article, we developed an electrochemical microfluidic paper-based device (EμPAD) for the non-enzymatic detection of Ascorbic Acid (AA) concentration in plasma using whole human blood. We combined LF1 blood plasma separation membrane and Whatman grade 1 filter paper to separate plasma from whole blood through wax printing. A screen-printed electrode (SPE) was modified with spherical-shaped MgFeO nanomaterial (n-MgF) to improve the catalytic properties of SPE.

A smartphone-integrated portable rotating platform for estimation of concentration level of plasma-creatinine using whole human blood.

The measurement of creatinine concentration is performed to monitor the renal health. The devices available in modern clinical laboratories for measuring creatinine concentration are accurate and provide results rapidly but may be prohibitively expensive for resource-poor settings. Therefore, developing an inexpensive yet accurate device for measuring creatinine concentration is needed.

Rapid determination of erythrocyte sedimentation rate (ESR) by an electrically driven blood droplet biosensor.

In healthcare practice, the sedimentation rate of red blood cells (erythrocytes) is a widely used clinical parameter for screening of several ailments such as stroke, infectious diseases, and malignancy. In a traditional pathological setting, the total time taken for evaluating this parameter varies typically from 1 to 2 h. Furthermore, the volume of human blood to be drawn for each test, following a gold standard laboratory technique (alternatively known as the Westergren method), varies from 4 to 5 ml.

Safety and Utility of Liver Biopsy During Bariatric Surgery in the New Zealand Setting.

Background: Asymptomatic liver disease is common in bariatric patients and can be diagnosed with intraoperative biopsy. This study aimed to establish the risk-benefit profile of routine liver biopsy, prevalence of clinically significant liver disease, relationship between liver pathology and body mass index, and compare outcomes between ethnic groups.

Methods: This retrospective cohort study included all patients who had index bariatric surgery at Auckland City Hospital between 2009 and 2016.

Pre-operative Bariatric Clinic Attendance Is a Predictor of Post-operative Clinic Attendance and Weight Loss Outcomes.

Aim: Our primary aim was to determine whether non-attendance at pre-operative clinics were associated with non-attendance at post-operative clinics and its influence on weight loss. We also sought to examine the relationship between gender, ethnicity and post-operative clinic attendance with respect to weight loss post-bariatric surgery.

Methods: A retrospective audit was performed for patients undertaking the bariatric surgery program at the Auckland City Hospital between 2013 and 2016.

Laparoscopic drainage of abdominal wall abscess from spilled stones post-cholecystectomy.

We present a case on abdominal wall abscess from spilled stones post-cholecystectomy and describe laparoscopic drainage as our choice of management. Mr M is a 75-year-old male who presented on multiple occasions to the hospital with right upper quadrant pain and fever post-laparoscopic cholecystectomy. He also required multiple courses of antibiotics.

Crohn's disease presenting as gastric outlet obstruction.

We present a unique presentation of Crohn's disease in a 25-year-old male with a 3-month history of progressive gastric outlet obstruction symptoms including reflux, vomiting, postprandial pain and weight loss, with no other symptoms. Multiple imaging investigations as well as gastroscopic biopsies revealed a non-specific prepyloric lesion, without evidence of malignancy. A distal gastrectomy was performed.

Clinical outcomes of a percutaneous cholecystostomy for acute cholecystitis: a multicentre analysis.

Background: The aim of this study was to review a series of consecutive percutaneous cholecystostomies (PC) to analyse the clinical outcomes.

Methods: All patients who underwent a PC between 2000 and 2010 were reviewed retrospectively for indications, complications, and short- and long-term outcomes.

Results: Fifty-three patients underwent a PC with a median age was 74 years (range 14-93).
