Giant mesenteric cyst of gastric origin: a case report with imaging findings

We present a very rare case of a giant gastric mesenteric cyst with ultrasonography (US) and computed tomography (CT) findings. An eight-year-old boy was referred for treatment of an intraabdominal cyst, known to exist for six years. On abdominal US, a giant, thin-walled, unilocular intraabdominal cyst was demonstrated, extending from the epigastric region to the pelvis and measuring 18 x 15 x 6 cm. In contrast-enhanced abdominal CT, the cyst was demonstrated as a giant, unilocular, hypodense, non-enhancing structure, located dominantly on the right side of the abdomen. During open surgery, the cyst was found to originate from the mesentery-serosa of the gastric antrum and was filled with serous fluid. The cyst was excised totally. Both surgery and pathology confirmed the diagnosis of mesenteric cyst, originating from the stomach. The patient was discharged in good health. US and CT were effective in defining the features of the giant gastric mesenteric cyst and in narrowing the differential diagnosis in favor of mesenteric cyst.     

Empathy,sympathy, and altruism—An evident triad based on compassion. A theoretical model for caring

Background

Based on existing confusion and a suggested contradiction regarding empathy and compassion in relation to caring science as well as in clinical health care.

Aim

The aim of the study was to find a knowledge base for the development of clinical caring science for, empathy, sympathy altruism, and compassion and their mutual relationship.

Design

A theoretical paper.

Results

The text discusses the different concepts separately, considering their history, research, obstacles, and bias and then brings them together in a concept model. The conclusion shows that empathy, sympathy, and altruism have no contradictions. Instead, they together form an evident triad based on compassion. Compassion is a prerequisite and a basis for the others to work. In clinical application, empathy is metaphorically a quality coming from the head, sympathy from the heart and altruism from the hand, merged in an attitude of compassion as a motif to care. The paper also reflects on the possibilities to increase and develop a compassionate mood and capacity by education and training.

Cerebrospinal fluid penetration of the colony-stimulating factor-1 receptor (CSF-1R) inhibitor,pexidartinib

Pexidartinib (PLX3397) is a colony-stimulating factor-1 receptor (CSF-1R) inhibitor under clinical evaluation for potential CNS tumor treatment. This study aims to evaluate plasma pharmacokinetic parameters and estimate CNS penetrance of pexidartinib in a non-human primate (NHP) cerebrospinal fluid (CSF) reservoir model. Five male rhesus macaques, each with a previously implanted subcutaneous CSF ventricular reservoir and central venous lines, were used. NHPs received a single dose of 40 mg/kg pexidartinib (human equivalent dose of 800 mg/m2), administered orally as 200 mg tablets. Serial paired samples of blood and CSF were collected at 0–8, 24, 48, and 72 h. Pexidartinib concentrations were assayed by Integrated Analytical Solutions, Inc. (Berkeley, CA, USA) using HPLC/MS/MS. Pharmacokinetic (PK) analysis was performed using noncompartmental methods. Samples from four NHPs were evaluable. Average (± SD) plasma PK parameters were as follows: Cmax = 16.50 (± 6.67) μg/mL; Tmax = 5.00 (± 2.58) h; AUClast = 250.25 (± 103.76) h*μg/mL; CL = 0.18 (± 0.10) L/h/kg. In CSF, pexidartinib was either quantifiable (n = 2), with Cmax values of 16.1 and 10.1 ng/mL achieved 2–4 h after plasma Tmax, or undetected at all time points (n = 2, LLOQCSF = 5 ng/mL). Pexidartinib was well-tolerated in NHPs, with no Grade 3 or Grade 4 toxicities. The CSF penetration of pexidartinib after single-dose oral administration to NHPs was limited.
