Abdominal aortic aneurysm patients remain at risk for delirium on the surgical ward after intensive care unit dismissal.

Background: The incidence of delirium following open abdominal aortic aneurysm (AAA) surgery is significant, with incidence rates ranging from 12% to 33%. However, it remains unclear on what level of care a delirium develops in AAA patients. The aim of this study was to investigate the incidence of delirium in the ICU and on the surgical ward after AAA surgery.

Does robotic rectal cancer surgery improve the results of experienced laparoscopic surgeons? An observational single institution study comparing 168 robotic assisted with 184 laparoscopic rectal resections.

Background: The role of robotic assistance in colorectal cancer surgery has not been established yet. We compared the results of robotic assisted with those of laparoscopic rectal resections done by two surgeons experienced in laparoscopic as well as in robotic rectal cancer surgery.

Methods: Two surgeons who were already experienced laparoscopic colorectal surgeons in 2005 started robotic surgery with the daVinci SI system in 2012.

Mortality after major amputation in elderly patients with critical limb ischemia.

Background: Owing to the aging population, the number of elderly patients with critical limb ischemia (CLI) has increased. The consequence of amputation is immense. However, at the moment, information about the mortality after amputation in the elderly vascular patients is unknown.

Press-fit bipolar radial head arthroplasty, midterm results.

Background: Theoretical advantages of bipolar compared with monopolar radial head arthroplasty include better accommodation of radiocapitellar malalignment, reduction of capitellar abrasion, and reduction of stress at the bone-implant interfaces. Our purpose was to report the midterm results of press-fit bipolar radial head arthroplasty.

Methods: Thirty patients were treated by press-fit bipolar radial head arthroplasty for acute fracture of the radial head, failed earlier treatment, or post-traumatic sequelae.

Pilot Study of the Pharmacokinetics of Cefotaxime in Critically Ill Patients with Acute Kidney Injury Treated with Continuous Renal Replacement Therapy.

The objective of this study was to describe the pharmacokinetics of cefotaxime (CTX) in critically ill patients with acute kidney injury (AKI) when treated with continuous renal replacement therapy (CRRT) in the intensive care unit (ICU). This single-center prospective observational pilot study was performed among ICU-patients with AKI receiving ≥48 h concomitant CRRT and CTX. CTX was administered intravenously 1,000 mg (bolus) every 6 h for 4 days.

The Size of the Radial Tuberosity is Not Related to the Occurrence of Distal Biceps Tendon Ruptures: A Case-Control Study.

Introduction: Hypertrophic changes at the radial tuberosity have traditionally been related to distal biceps tendon degeneration and rupture. From supination to pronation of the forearm, the space available for the distal biceps tendon between de lateral ulna and radial bicipital tuberosity (RBT) decreases by almost 50%. A hypertrophic change at the radial tuberosity further reduces this space with impingement of the distal biceps tendon as a result.

The clinical applicability of an automated plethysmographic determination of the ankle-brachial index after vascular surgery.

An automated ankle-brachial index device could lead to potential time savings and more accuracy in ankle-brachial index-determination after vascular surgery. This prospective cross-sectional study compared postprocedural ankle-brachial indices measured by a manual method with ankle-brachial indices of an automated plethysmographic method. Forty-two patients were included.

Refixation techniques and approaches for distal biceps tendon ruptures: a systematic review of clinical studies.

Background: Surgical fixation is the preferred method of treatment for the ruptured distal biceps tendon in active patients. To date, no fixation technique has been proven superior in a clinical setting. The purpose of the study was to systematically review the available literature on approach and fixation methods for distal biceps tendon repair in a clinical setting and to determine the optimal fixation methods of the distal biceps tendon on the radial tuberosity.

New aspects of delirium in elderly patients with critical limb ischemia.

Objective: The primary objective was to identify possible risk factors for delirium in patients with critical limb ischemia undergoing surgery. The secondary objective was to study the effect of delirium on complications, the length of hospital stay, health care costs, and mortality.

Methods: All patients 65 years or older with critical limb ischemia undergoing surgery from February 2013 to July 2014 at Amphia Hospital, were included and followed up until December 31, 2014.

Reliability of the Inverse Water Volumetry Method to Measure the Volume of the Upper Limb.

Background: Lymphedema of the upper extremity is a common side effect of lymph node dissection or irradiation of the axilla. Several techniques are being applied in order to examine the presence and severity of lymphedema. Measurement of circumference of the upper extremity is most frequently performed.

The effect of trauma and patient related factors on radial head fractures and associated injuries in 440 patients.

Background: Radial head fractures are commonly interpreted as isolated injuries, and it is assumed that the energy transferred during trauma has its influence on the risk on associated ipsilateral upper limb injuries. However, relationships between Mason classification, mechanism of injury, and associated injuries have been reported only once before in a relatively small population. The purpose of this study was to define whether trauma mechanism and patient related factors are of influence on the type of radial head fracture and associated injuries to the ipsilateral upper limb in 440 patients.

Defining indications for selective chest radiography in the first 24 hours after cardiac surgery.

Objective: In the intensive-care unit (ICU), chest radiographs (CXRs) are frequently obtained routinely for postoperative cardiac surgery patients, despite the fact that the efficacy of routine CXRs is known to be low. We investigated the efficacy and safety of CXRs performed after cardiac surgery for specified indications only.

Methods: In this observational cohort study, we prospectively included all patients who underwent conventional major cardiac surgery by median sternotomy in the year 2012.

Current factors of fragility and delirium in vascular surgery.

Background: Vascular surgery patients are frequently deemed to be in a frail clinical condition and at risk for delirium. Therefore, we evaluated the incidence and independent perioperative risk factors for delirium. In addition, we describe factors on frailty in the various vascular disease groups in current practice.

Surgical site infection after multiple groin incisions in peripheral vascular surgery.

Background: Patients with peripheral arterial disease (PAD) are at risk for revision surgery in the groin and therefore at potential risk for surgical site infections (SSIs). In an observational study, a cohort of patients with peripheral arterial disease was followed to examine the effect of different incision intervals on SSI-free survival.

Methods: Patients, needing peripheral vascular surgery because of PAD, were retrieved from a prospectively collected database on SSIs after vascular surgery between March 2009 and January 2012, the group consisting of 720 patients.

The value of routine chest radiographs after minimally invasive cardiac surgery: an observational cohort study.

Background: Chest radiographs (CXRs) are obtained frequently in postoperative cardiac surgery patients. The diagnostic and therapeutic efficacy of routine CXRs is known to be low and the discussion regarding the safety of abandoning these CXRs after cardiac surgery is still ongoing. We investigated the value of routine CXRs directly after minimally invasive cardiac surgery.

A statistical model to predict the reduction of lichenification in atopic dermatitis.

Acute symptoms of atopic dermatitis (AD), such as erythema, oedema/papulations and excoriations, respond quickly to topical corticosteroid treatment. Conversely, lichenification is regarded as a troublesome non-acute symptom of chronic AD which can take months of treatment before any improvement is seen. However, very little data actually support this opinion.

Azithromycin maintenance treatment in patients with frequent exacerbations of chronic obstructive pulmonary disease (COLUMBUS): a randomised, double-blind, placebo-controlled trial.

Background: Macrolide resistance is an increasing problem; there is therefore debate about when to implement maintenance treatment with macrolides in patients with chronic obstructive pulmonary disease (COPD). We aimed to investigate whether patients with COPD who had received treatment for three or more exacerbations in the previous year would have a decrease in exacerbation rate when maintenance treatment with azithromycin was added to standard care.

Methods: We did a randomised, double-blind, placebo-controlled, single-centre trial in The Netherlands between May 19, 2010, and June 18, 2013.

Significant changes in the practice of chest radiography in Dutch intensive care units: a web-based survey.

Background: ICU patients frequently undergo chest radiographs (CXRs). The diagnostic and therapeutic efficacy of routine CXRs are now known to be low, but the discussion regarding specific indications for CXRs in critically ill patients and the safety of abandoning routine CXRs is still ongoing. We performed a survey of Dutch intensivists on the current practice of chest radiography in their departments.

The knowledge, attitudes and practices of wintersun vacationers to the Gambia toward prevention of malaria: is it really that bad?

Background: Each year clusters of imported malaria cases are observed in Dutch wintersun vacationers returning from The Gambia. To gain more insight in the travel health preparation and awareness of these travellers, the knowledge, attitudes and practices (KAP) of this travel group was studied by analysing the data of the Continuous Dutch Schiphol Airport Survey.

Methods: In the years 2002 to 2009 a questionnaire-based survey was conducted at the Dutch Schiphol Airport with the aim to study the KAP, i.

A novel finding: the effect of nurse practitioners on the relation to quality of life, anxiety, and depressive symptoms in vascular surgery.

Background: An increasing number of vascular surgery units expand their team with nurse practitioners (NPs) to optimize patient care. There are no previously performed studies which assessed the influence of NPs on patients' quality of life (QoL), anxiety, and depressive symptom levels. The transition in care from surgeon to NP in the vascular surgery unit of our hospital facilitated the comparison of both groups.

Procalcitonin in the recognition of complications in critically ill surgical patients.

Background: Procalcitonin (PCT) is a relatively new, promising indirect parameter for infection. In the intensive care unit (ICU) it can be used as a marker for sepsis. However, in the ICU there is a need for reliable markers for clinical deterioration in the critically ill patients.

Trends in the knowledge, attitudes and practices of travel risk groups toward prevention of hepatitis B: results from the repeated cross-sectional Dutch Schiphol Airport Survey 2002-2009.

Background: Previous studies investigating the travellers' knowledge, attitudes and practices (KAP) profile indicated an important educational need among those travelling to risk destinations.

Methods: In the years 2002-2009 an annually repeated cross-sectional questionnaire-based survey was conducted at the Dutch Schiphol Airport with the aim to study trends in KAP of travel risk groups toward prevention of hepatitis B. The frequently encountered risk groups last-minute travellers, solo-travellers, business travellers, travellers visiting friends and relatives (VFR) and elderly travellers were specifically studied.

Midterm follow-up of quality of life following peripheral bypass surgery.

Background: Peripheral bypass surgery is an important treatment option for patients with peripheral arterial disease. Short-term results of quality of life (QoL) after peripheral bypass surgery showed an increase in QoL at 3 months. Little is known about QoL at more than 2 years of follow-up.

A double-blind randomized study comparing plasma level-targeted dose imipramine and high-dose venlafaxine in depressed inpatients.

Objective: To compare the efficacy of plasma level-targeted dose imipramine and high-dose venlafaxine in depressed inpatients in a randomized double-blind study.

Methods: The study included 85 patients with a diagnosis of major depressive episode according to the DSM IV criteria and a 17-item Hamilton Rating Scale for Depression (HAM-D) score ≥ 17. Patients were randomized to imipramine or venlafaxine.

Association of perioperative troponin and atrial fibrillation after coronary artery bypass grafting.

Objectives: Prediction of atrial fibrillation (AF) after coronary artery bypass grafting (CABG) may lead to preventive or early treatment and improved outcome. We investigated the association of serial perioperative cardiac troponin T (cTNT) measurements with postoperative AF in patients undergoing CABG.

Methods: In a retrospective analysis of prospectively collected data, 3148 patients undergoing elective CABG were evaluated.
