Mirizzi Syndrome With Bouveret Syndrome: A Rare Amalgam.

Cureus 2022 Apr 16;14(4):e24187. Epub 2022 Apr 16.

Radiology and Interventional Radiology, All India Institute of Medical Sciences, Jodhpur, IND.

Mirizzi and Bouveret syndromes are uncommon but important complications of calculous cholecystitis. Mirizzi syndrome commonly presents with jaundice due to extrinsic compression on the common bile duct by an impacted stone at the gall bladder infundibulum, whereas Bouveret syndrome presents with gastric outlet obstruction due to a large stone in the duodenum. Our case is a 65-year-old lady who presented with pain in the right upper abdomen associated with nausea and vomiting. Read More

Brain Nerve 2022 May;74(5):652-659

Department of Immunology, Multiple Sclerosis Center, National Center of Neurology and Psychiatry, National Institute of Neuroscience.

Myalgic encephalitis/chronic fatigue syndrome (ME/CFS) is an acquired intractable disease characterized by profound fatigue, post-exertional malaise, sleep disturbance, cognitive impairment, and orthostatic intolerance, among other features. The onset often follows an infectious episode. Importantly, the various types of autonomic dysfunctions, pain, and intolerance to various stimuli in ME/CFS patients are intrinsically different from the "fatigue" of healthy individuals. Read More

Peptidomics analysis reveals changes in small urinary peptides in patients with interstitial cystitis/bladder pain syndrome.

Sci Rep 2022 May 18;12(1):8289. Epub 2022 May 18.

Department of Chemistry, University of Nebraska-Lincoln, Lincoln, NE, USA.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic and debilitating pain disorder of the bladder and urinary tract with poorly understood etiology. A definitive diagnosis of IC/BPS can be challenging because many symptoms are shared with other urological disorders. An analysis of urine presents an attractive and non-invasive resource for monitoring and diagnosing IC/BPS. Read More

Update on the diagnosis and management of the autosomal dominant acute hepatic porphyrias.

J Clin Pathol 2022 May 18. Epub 2022 May 18.

Medical Biochemistry and Immunology, University Hospital of Wales Healthcare NHS Trust, Cardiff, UK.

The autosomal dominant acute hepatic porphyrias (AHPs), acute intermittent porphyria, hereditary coproporphyria (HCP) and variegate porphyria (VP), are low penetrance adult onset disorders caused by partial deficiency of enzymes of haem biosynthesis. All are associated with acute neurovisceral attacks, which are a consequence of the increased hepatic demand for haem triggered by hormones, stress, drugs or systemic infections which leads to upregulation of the pathway and overproduction of haem precursors 5-aminolaevulinic acid (ALA) and porphobilinogen (PBG). Acute episodes are characterised by severe abdominal pain, nausea, vomiting, hyponatraemia, hypertension and tachycardia, behavioural disturbance and can progress to include seizures, peripheral motor neuropathy and posterior reversible encephalopathy syndrome if undiagnosed and untreated.

Lateral epicondylitis: New trends and challenges in treatment.

World J Orthop 2022 Apr 18;13(4):354-364. Epub 2022 Apr 18.

Department of Orthopedics and Traumatology, University Hospital Queen Giovanna-ISUL, Medical University of Sofia, Sofia 1527, Bulgaria.

Lateral epicondylitis (LE) is a chronic aseptic inflammatory condition caused by repetitive microtrauma and excessive overload of the extensor carpi radialis brevis muscle. This is the most common cause of musculoskeletal pain syndrome in the elbow, inducing significant pain and limitation of the function of the upper limb. It affects approximately 1-3% of the population and is frequently seen in racquet sports and sports associated with functional overload of the elbow, such as tennis, squash, gymnastics, acrobatics, fitness, and weight lifting.

Delayed recognition of Type II decompression sickness in a diver with chronic atrial fibrillation.

Undersea Hyperb Med 2022 Second Quarter;49(2):563-568

Duke University, Department of Anesthesiology, Division of Hyperbaric Medicine and Environmental Physiology, Durham, North Carolina U.S.

Introduction: This case report describes an initially overlooked Type II decompression sickness (DCS) occurrence that was confused with a cerebral vascular accident in a patient with chronic atrial fibrillation (AF). The purpose of this case report is to reinforce the maxim that DCS needs to be suspected anytime a scuba diver experiences signs or symptoms compatible with DCS after completing a scuba dive.

Methods: A 71-year-old scuba diver with a history of AF and who was taking warfarin made four dives, all with maximum depths less than 60 fsw (20 msw) over a 10-hour interval. Read More

Inflammation-Independent Antinociceptive Effects of DF2755A, a CXCR1/2 Selective Inhibitor: A New Potential Therapeutic Treatment for Peripheral Neuropathy Associated to Non-Ulcerative Interstitial Cystitis/Bladder Pain Syndrome.

Front Pharmacol 2022 28;13:854238. Epub 2022 Apr 28.

Research and Early Development, Dompé Farmaceutici S.p.A., L'Aquila, Italy.

Interstitial cystitis (IC)/bladder pain syndrome (BPS) is a chronic bladder disease of unknown etiology characterized by urinary frequency and episodic and chronic pain. Analgesic treatments for IC/BPS are limited, especially for patients with non-Hunner (non-ulcerative) type IC who usually have poor overall outcomes. Here, we demonstrate that oral treatment with DF2755A, a potent and selective inhibitor of chemokine receptors CXCR1/2, can prevent and reverse peripheral neuropathy associated to non-Hunner IC/BPS by directly inhibiting chemokine-induced excitation of sensory neurons.

Division Gastroenterology-Hepatology, Department of Internal Medicine, Maastricht University Medical Center+, P.O. Box 5800, 6202 AZ Maastricht, The Netherlands.

Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) share common culprit foods and potential pathophysiological factors. However, how diet may contribute to disease course and whether this differs between both entities is unclear. We therefore investigated the association of dietary indices with intestinal inflammation and gastrointestinal symptoms in both IBD and IBS patients. Read More

Sex differences in pain-related behaviors and clinical progression of disease in mouse models of colonic pain.

Pain 2022 May 13. Epub 2022 May 13.

National Center for Complementary and Integrative Health, National Institutes of Health, Bethesda, MD, United States.

Abstract: Previous studies have reported sex differences in irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) patients, including differences in visceral pain perception. Despite this, sex differences in behavioral manifestations of visceral pain and underlying pathology of the gastrointestinal tract have been largely understudied in preclinical research. In this study, we evaluated potential sex differences in spontaneous nociceptive responses, referred abdominal hypersensitivity, disease progression and bowel pathology in mouse models of acute and persistent colon inflammation.

J Med Case Rep 2022 May 12;16(1):201. Epub 2022 May 12.

Laboratoire de Neurobiologie Orofaciale-LabNOF (EA7543), UFR. d'Odontologie, Université Paris Cité, 5 rue Garancière, 75006, Paris, France.

Background: Elongation of the styloid process associated with oropharyngeal pain and dysphagia is known as Eagle's syndrome, a condition whose pathophysiology is still a matter of debate. Given its low prevalence and complex symptomatology, this syndrome is often misdiagnosed, leading to chronic pain and medical nomadism. A 51-year-old woman of African origin with 3-year history of left-side oropharyngeal pain and worsening dysphagia consulted several health professionals. Read More
