Unmasking Multiple Myeloma: The Importance of Suspecting Malignancy in Atypical Chronic Pain Mimicking Degenerative Conditions-A Case Report.

Heightened clinical vigilance for multiple myeloma is essential in patients presenting with atypical chronic pain progression. Symptoms may overlap with degenerative musculoskeletal conditions, frequently leading to misdiagnosis. This underscores the necessity of a thorough evaluation when symptoms are refractory to conventional therapies, in order to facilitate timely diagnosis and effective management of malignancy.

Modelling blood flow in the circle of Willis in continuous flow left ventricular assist devices: possible relevance to strokes.

Purpose: Despite significant improvements in the design and performance of continuous flow left ventricular assist devices (CFLVADs), one of the most important reasons hampering further penetration of this technology is the occurrence of adverse events, especially strokes. One of the well-known risk factors for strokes is hypertension which is particularly common in patients undergoing a CFLVAD implant. While the device is implanted in the heart, strokes happen due to pathology in the brain and we hypothesised that modelling the blood flow in the circle of Willis might shed light on the causation of strokes in this situation.

A case of autoimmune haemolytic anaemia associated with mediastinal teratoma.

Autoimmune hemolytic anemia (AIHA) secondary to mediastinal teratoma is a very rare clinical entity. They can be primary or secondary to any infections, malignancy, etc. Yet at times, there could be a delay in the diagnosis.

Primary pulmonary lymphoma: a surgical series.

Primary pulmonary lymphoma (PPL) is a rare entity often underdiagnosed due to its non-specific clinical presentation. Our aim is to share our experience in the management of these lesions, which should be considered in the differential diagnosis of nodules affecting the lung parenchyma. We retrospectively studied a total of 14 patients who had undergone surgery between 2013 and 2021.

A case of simultaneous bilateral pulmonary resection for arteriovenous pulmonary malformation.

Pulmonary arteriovenous malformation (PAVM) is a congenital vascular pathology, which is caused by the presence of a direct connection between the branches of the artery and the veins of the lungs, and the discharge of unoxygenated blood into the arterial bed. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and, in some cases, may be accompanied with severe circulatory disorders.

Inferential statistics for cardiothoracic surgeons: Part 3 - drawing valid conclusions from clinical data.

Inferential statistics enable researchers to make predictions about a population based on sample data. This involves hypothesis testing where the null hypothesis assumes no effect, and the alternative hypothesis suggests a significant effect. Testing requires assumptions like normality and independence to be validated using tests like Shapiro-Wilk or Levene's for normality and variance.

Patient-centred newer testing methods for major cardiac disorders.

Unlabelled: Testing methods of detecting various cardiac biomarkers play a significant influence in determining and treating cardiac-related conditions and ultimate prognosis. With the increasing global prevalence of cardiac disease, the importance of rapid testing methods in diagnosis and management has grown tremendously. The point-of-care testing (POCT) method is a potential biochemical diagnostic technique that may overcome the issue of delayed laboratory results, particularly in regions with limited access to advanced laboratory equipment or resource-constrained.

Isolated right superior vena cava drainage into the left atrium.

Isolated right superior vena cava (RSVC) drainage into the left atrium (LA) is a rare congenital anomaly, presenting diagnostic and management challenges. This study presents two cases of isolated RSVC drainage into the LA alongside a comprehensive literature review to improve understanding and delineate optimal surgical approaches. The study describes two cases of isolated RSVC drainage into the LA and their surgical management.

Exploring psychosomatic congruence: The effect of focusing on body parts as a body-oriented mentalization process.

Background/objective: : Patients with somatic symptoms are considered to have a deficiency in body-oriented mentalization; that is, the ability to perceive and interpret bodily sensations in relation to psychological states. We introduce the novel concept of psychosomatic congruence-the alignment of physical sensations with cognition and emotional states, which leads to behaviors that synchronize physical manifestations with emotional experiences and internal reflections. Despite its clinical relevance, this concept has not been empirically examined.

Prior nonarthroplasty shoulder surgery and modifiable risk factors negatively affect patient outcomes after shoulder arthroplasty.

Background: Total shoulder arthroplasty frequently is performed in patients with a history of shoulder surgery. The purpose of this study was to evaluate clinical outcomes after primary shoulder arthroplasty in patients with a history of nonarthroplasty shoulder surgery, and whether certain modifiable risk factors (MRFs) were negatively associated with final outcome measures. The secondary purpose was to determine if costs or complications were higher in patients with prior shoulder surgery.

Can Patient-Reported Outcomes Measurement Information System estimate high-impact chronic pain after total shoulder arthroplasty?

Background: Identification of high-impact chronic pain (HICP) among patients receiving total shoulder arthroplasty (TSA) may allow for the design and implementation of tailored pain interventions to address the negative impact on postoperative outcomes and quality of life. This analysis sought to determine if Patient-Reported Outcome Measurement Information System (PROMIS) measures could be used to estimate HICP status following TSA.

Methods: This was a secondary analysis of a cohort of patients (n = 227) who received a TSA at a single, academic medical center, of whom 25 (11.

The clinical course and outcomes following arthroscopic frozen shoulder 360° release.

Background: Frozen shoulder (FS) is a debilitating inflammatory condition affecting the shoulder capsule that causes significant pain and stiffness. Its etiology, pathophysiology, and treatment remain poorly understood. Although regarded as self-limiting, FS can have profound implications on the activities of daily living and usually takes 1-4 years to resolve on its own accord.

Coronoid height index: a reliable and reproducible technique for quantifying coronoid bone loss in elbow instability.

Background: Coronoid fracture size is one important factor in decision-making on surgical vs. nonsurgical management. There is currently no reliable, standardized technique to measure coronoid fracture size or bone loss.

Virtual assessment of internal rotation in reverse shoulder arthroplasty based on statistical shape models of scapular size.

Background: The purpose of this study was to assess impingement-free internal rotation (IR) in a virtual reverse shoulder arthroplasty simulation using a Statistical Shape Model based on scapula size.

Methods: A database of over 10,000 scapulae utilized for preoperative planning for shoulder arthroplasty was analyzed with a Statistical Shape Model to obtain 5 scapula sizes including the mean and 2 standard deviations. For each scapula model, one glenosphere size (33-42 mm) was selected as the best fit based on consensus among 3 shoulder surgeons.

Glenoid wear and migration pattern of a humeral head resurfacing implant: a prospective study using radio stereometric analysis.

Background: The humeral head resurfacing arthroplasty (HHR) is normally used as a hemi shoulder arthroplasty and has been in use for the treatment of Gleno-Humeral osteoarthritis (OA) of the shoulder for more than 30 years. Some studies, however, shows that anatomical total shoulder arthroplasty provides better improvement in function than a HHR for patients with OA. Reasons for this may be a progressive glenoid wear (GW) or loosening of the HHR.

Improved patient reported outcomes with knotless double-row rotator cuff repair with and without lateral row biceps tenodesis at 2- and 5-years.

Background: The purpose of this study is to report outcomes of an arthroscopic knotless double-row (DR) rotator cuff repair (RCR) technique at 2- and 5- years postoperatively, and to compare clinical outcomes in patients undergoing knotless DR RCR with incorporated lateral row biceps tenodesis (LRT) vs. those without LRT.
