A rare case of solitary plasmacytoma mimicking submucosal lesion of ascending colon: a case report and literature review.

Solitary primary extraosseous plasmacytoma is a rare disease in the gastrointestinal tract, recently classified as an "exceptional" tumor of the colon site. The real incidence (one case/population/year) is unknown but reasonably less than 1/10,000,000 cases/year with very few descriptions in the literature. The rare cases described in the literature are often diagnosed after surgery for perforation and with predominant localization of the left colon.

Segmental Thoracic Spinal Anesthesia for Laparoscopic Cholecystectomy with the "Hypobaric" Technique: A Case Series.

Purpose: Several studies have applied lumbar spinal anesthesia (SA) with isobaric/hyperbaric bupivacaine and opioids in elective laparoscopic cholecystectomy (LC), documenting a superiority of the methodic over general anesthesia (GA) in terms of perioperative pain, nausea, and vomiting, though with a notable incidence of intraoperative right shoulder pain, potentially responsible for conversion to GA. This case series presents an opioid-free scheme of segmental thoracic spinal anesthesia (STSA) with hypobaric ropivacaine, reporting its benefits mainly in terms of shoulder pain occurrence.

Patients And Methods: Hypobaric STSA was performed in nine patients undergoing elective LC between May 1 and September 1, 2022.

Reduced levels of plasma selenium are associated with increased inflammation and cardiovascular disease in an Italian elderly population.

Selenium (Se) is an essential micronutrient for human health that protects from oxidative damage. Se deficiency has been associated with the development of cardiovascular diseases (CVD). In this study we aimed to investigate the association between Se status, CVD risk, cardio-metabolic and inflammatory markers in elderly population.

Continuous thoracic spinal anesthesia with local anesthetic plus midazolam and ketamine is superior to local anesthetic plus fentanyl in major abdominal surgery.

Background: Limited studies have applied thoracic continuous spinal anesthesia in abdominal surgery, relying exclusively on opioids. This retrospective study analyzes 2 different schemes of thoracic continuous spinal anesthesia and postoperative analgesia in elderly patients undergoing major abdominal surgery.

Methods: A total of 98 patients aged ≥ 75 years were divided into 2 groups.

Thoracic continuous spinal anesthesia for high-risk comorbid older patients undergoing major abdominal surgery: one-year experience of an Italian geriatric hospital.

Background: General anesthesia is associated with high morbidity/mortality in comorbid older adults. Thoracic continuous spinal anesthesia/analgesia (TCSA) may be an alternative for major abdominal surgery. We report a one-year experience of the use of TCSA in an Italian geriatric center.

ZnT8 Arg325Trp polymorphism influences zinc transporter expression and cytokine production in PBMCs from patients with diabetes.

Aims: ZnT8 Arg325Trp polymorphism has been associated with type 2 diabetes (T2DM) susceptibility. The Arg-325 risk variant shows accelerated zinc (Zn) transport kinetic and reduced glucose-stimulated insulin secretion in pancreatic cells. However, it remains unexplored the role of Znt8 polymorphism in the regulation of Zn homeostasis and inflammatory response in peripheral blood mononuclear cells (PBMCs) from T2DM patients.

A gas-filled abdominal cyst in an elderly woman: A giant colonic diverticulum case report.

Introduction: Giant colonic diverticulum (GCD), a rare complication of the diverticular disease, can present with a wide range of nonspecific symptoms as abdominal pain and bowel obstruction. Its diagnosis represents a challenge that mainly depends on imaging findings.

Presentation Of Case: We report the case of a 79 year-old female patient that came to our emergency department complaining of 5-day history of hypogastric pain and constipation.

Small bowel adenocarcinoma (SBA) three years after colonic adenocarcinoma in an elderly patient: Case report in a National Institute of Health and Aging (INRCA) and review of the literature.

Introduction: Adenocarcinoma of the small intestine is a rare malignancy (the annual incidence in the USA is approximately 3.9 cases per million persons with median age between 60 and 70 years) with limited data available to guide therapeutic decisions. Nonspecific signs and symptoms associated with difficulty in performing small bowel examination is the cause of delayed diagnosis made between 6 and 9 months after appearance of symptoms with the majority of patients presenting with late stage disease and either lymph node involvement or distant metastatic disease.

Superior Mesenteric Artery Syndrome-Believe in it! Report of a Case.

We present a case of a man with amyotrophic lateral sclerosis who developed superior mesenteric artery syndrome (SMAS) following the confection of feeding jejunostomy. He was successfully managed by conservative treatment. Left lateral positioning during enteral feeding allowed quick resolution of the occlusive state.

The +838 C/G MT2A polymorphism, metals, and the inflammatory/immune response in carotid artery stenosis in elderly people.

Carotid artery stenosis (CS) is a well-established risk factor for stroke. Increased proinflammatory chemokines, enhanced metallothionein (MT), and altered metal homeostasis may play roles in atherosclerosis progression and plaque destabilization. MT may sequester zinc during chronic inflammation, provoke zinc deficiency, and modulate NK cell cytotoxicity.

1267 HSP70-2 polymorphism as a risk factor for carotid plaque rupture and cerebral ischaemia in old type 2 diabetes-atherosclerotic patients.

Patients with type 2 diabetes mellitus (NIDDM) are at risk for macrovascular disease complications, such as myocardial infarction (MI) or stroke from plaque rupture. Cytokines play a key role in plaque vulnerability. IFN-gamma inhibits collagen synthesis thereby affecting plaque stability.

The -174G/C polymorphism of IL-6 is useful to screen old subjects at risk for atherosclerosis or to reach successful ageing.

High levels of IL-6 are coupled with impaired immune efficiency, morbidity and mortality in ageing. Elderly men with GG (C-) genotype in -174 locus of IL-6 promoter are disadvantaged for longevity due to higher IL-6 than CG or CC (C+) carriers. As IL-6 increases in atherosclerosis, the study of the polymorphism of IL-6 may be a useful tool in identifying old subjects at risk for atherosclerosis.

Overexpression of functionally coupled cyclooxygenase-2 and prostaglandin E synthase in symptomatic atherosclerotic plaques as a basis of prostaglandin E(2)-dependent plaque instability.

Background: Studies have implicated a role for prostaglandin (PG) E(2)-dependent matrix metalloproteinase (MMP) biosynthesis in the rupture of atherosclerotic plaque. Cyclooxygenase-2 (COX-2) and PGE synthase (PGES) are coregulated in nucleated cells by inflammatory stimuli. The aim of this study was to characterize the expression of COX-2 and PGES in carotid plaques and to correlate it with the extent of inflammatory infiltration and MMP activity and with clinical features of patients' presentation.

Efficacy of rifampin-levofloxacin as a prophylactic agent in preventing Staphylococcus epidermidis graft infection.

Objectives: To investigate the efficacy of levofloxacin in the prevention of vascular prosthetic graft infection in a rat model.

Methods: Graft infections were established in the subcutaneous tissue of 225 male Wistar rats by implantation of Dacron prostheses followed by topical inoculation with methicillin-susceptible and methicillin-resistant S. epidermidis.

Aneurysm of a jejunal branch of the superior mesenteric artery in a patient with Marfan's syndrome.

A case of post-traumatic aneurysm of a jejunal branch of the superior mesenteric artery in a patient with Marfan's syndrome is reported. Ascending aortic involvement is well known in Marfan's syndrome but no association with visceral artery aneurysms has been previously described. The blunt abdominal trauma preceding the detection of the aneurysm may have been the precipitating cause in a predisposed patient.

alpha-MSH modulates local and circulating tumor necrosis factor-alpha in experimental brain inflammation.

Tumor necrosis factor (TNF-alpha) underlies pathological processes and functional disturbances in acute and chronic neurological disease and injury. The neuroimmunomodulatory peptide alpha-MSH modulates actions and production of proinflammatory cytokines including TNF-alpha, but there is no prior evidence that it alters TNF-alpha induced within the brain. To test for this potential influence of the peptide, TNF-alpha was induced centrally by local injection of bacterial lipopolysaccharide (LPS).

A potential mechanism of local anti-inflammatory action of alpha-melanocyte-stimulating hormone within the brain: modulation of tumor necrosis factor-alpha production by human astrocytic cells.

The proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) occurs in CNS tissue in neurological disorders, infection, and injury. Its excessive production is believed to contribute to local pathology, in which case modulation of TNF-alpha production should promote survival of neural tissue. The neuropeptide alpha-melanocyte stimulating hormone [alpha-MSH (1-13)] inhibits TNF-alpha production in vivo and in vitro, and in this research we tested the capacity of the peptide, and of an anti-inflammatory COOH-terminal tripeptide fragment of it, to inhibit TNF-alpha production induced by bacterial endotoxin in cells of a human glioma line (A-172, anaplastic astrocytoma cells).
