A Rare Presentation of Undifferentiated Pleomorphic Sarcoma in the Subpectoral Space.

Soft tissue sarcomas (STS) are often described as asymptomatic, rapidly expanding masses, particularly in the extremities or trunk. Undifferentiated pleomorphic sarcoma (UPS), a high-grade variant of STS, ranks as the second most prevalent subtype in the United States. It predominantly affects males between their fifth and seventh decades.

A Case of Non-purpuric Neonatal Alloimmune Thrombocytopenia Secondary to ABO Incompatibility.

Neonatal alloimmune thrombocytopenia (NAIT) is a condition in which maternal IgG antibodies are directed against fetal platelets and cross the placenta, destroying fetal thrombocytes. It is typically caused by maternal alloimmunization to human leukocyte antigens (HLA). ABO incompatibility, on the other hand, is a rare cause of NAIT due to the variable expression of ABO antigens on platelets.

Adult-Onset Immunoglobulin A Vasculitis Following Hemodialysis Treatment: An Unusual Presentation.

Immunoglobulin A (IgA) vasculitis, formerly known as Henoch-Schönlein purpura (HSP), is a small vessel vasculitis due to perivascular deposition of dominant IgA immune complexes. It classically presents with symptoms such as palpable purpura, abdominal pain, kidney dysfunction, and joint pain. It most commonly affects children less than 10 years old.

Dying still matters in the age of COVID-19.

The ongoing COVID-19 pandemic is having a significant impact on people with palliative care needs.

Engaging clinicians in evidence based policy development: the case of nursing documentation.

A lack of consistent policy direction, revealed by a review of nursing and midwifery documentation, presented researchers with an opportunity to engage clinicians in the process of evidence based policy development. By utilising the framework informed by both practice development and the principles of evidence based practice, clinicians were taken through an education program and a series of activities to develop their skills in discerning how research evidence and other literature can inform policy development. The clinicians' involvement maximised their investment in the final policy.

Manual segmentation of DXA scan images results in reliable upper and lower extremity soft and rigid tissue mass estimates.

Quantification of segment soft and rigid tissue masses in living people is important for a variety of clinical and biomechanical research applications including wobbling mass modeling. Although Dual-energy X-ray Absorptiometry (DXA) is widely accepted as a valid method for this purpose, the reliability of manual segmentation from DXA scans using custom regions of interest (ROIs) has not been evaluated to date. Upper and lower extremity images of 100 healthy adults who underwent a full body DXA scan in the supine position were manually segmented by 3 measurers independently using custom ROIs.

Upper extremity soft and rigid tissue mass prediction using segment anthropometric measures and DXA.

Regression equations for predicting bone mineral content (BMC), fat mass (FM), lean mass (LM), and wobbling mass (WM) of living people from simple anthropometric measures (segment lengths, circumferences, breadths, and skin folds) have been reported in the literature for the lower extremities, but are lacking for the upper extremities. Multiple linear stepwise regression was used to generate such equations for the arm, forearm, and forearm and hand segments of healthy university aged people (38 males, 38 females). Actual tissue masses were obtained from full body Dual-energy X-ray Absorptiometry (DXA) scans and were used to validate the developed equations with an independent sample of 24 participants (12 male, 12 female).

Reliability of upper and lower extremity anthropometric measurements and the effect on tissue mass predictions.

Accurate modeling of soft tissue motion effects relative to bone during impact requires knowledge of the mass of soft and rigid tissues in living people. Holmes et al., [2005.

DNA densitometry of colorectal cancer.

DNA analysis was assessed by densitometry for 281 cases of colorectal adenocarcinoma. Detection of aneuploidy in a single case rose from 65% if one, to 92.5% when three or more sections, were analysed.

The role of flow cytometry in carcinoma of the colon and rectum.

Flow cytometry was performed upon 312 patients with adenocarcinoma of the colon and rectum, satisfactory results being obtained with 275 (108 diploid, 130 aneuploid and 37 tetraploid). The proportion of nondiploid instances increased from 28 percent if one, to 80 percent when six specimens were assessed per patient. Reproducibility of the technique showed substantial agreement in the assessment of deoxyribonucleic acid ploidy (Kappa value equals 0.

AIDS: clinical and ethical issues on a psychiatric unit.

Using a case illustration, this paper describes how AIDS has affected psychiatric practice on an inpatient unit. The clinical, ethical and administrative issues are discussed from a multi-disciplinary perspective. The issues are discussed as 1.

Syngamosis, an unusual cause of asthma: the first reported case in Canada.

The first case of syngamosis in a human in Canada is reported. The patient, a traveller to the Caribbean islands, presented with a chronic dry cough. The nematode Syngamus laryngeus is found in wild and domestic birds and mammals in the tropics and subtropics.
