Opioid medications are a pillar of acute and chronic analgesia, though their use is often accompanied by side-effects, such as opioid-induced constipation. Unfortunately, tolerance rarely develops to this untoward side effect. This review presents the background, evidence, and indications for the use of Naldemedine (Brand name Symproic 0.2 mg tablets) to treat opioid-induced constipation.

This is a comprehensive review of the literature regarding the use of Lofexidine for opiate withdrawal symptoms. It covers the background and necessity of withdrawal programs and the management of withdrawal symptoms and then covers the existing evidence of the use of Lofexidine for this purpose.

Research suggests that existential, spiritual, and religious issues are important for patient's psychological adjustment when living with chronic pain and multiple sclerosis. However, there is a paucity of studies investigating how physicians experience and approach these patients' needs.

The patient is a 67-year-old Caucasian male with a past medical history of diabetes mellitus type 2, coronary artery disease (CAD) status post stent placement, renal cell carcinoma (RCC) status post left nephrectomy and bilateral adrenalectomy secondary to metastatic disease, and aspergillus pneumonia who was transferred from an outside hospital for evaluation of progressively worsening pulsating right temple and retrobulbar headache. Initial studies ruled out glaucoma, giant cell arteritis, and stroke, or aneurysmal pathology. The only positive finding was right sphenoid sinus disease on imaging that had caused bony destruction and infiltration of the right orbital apex. Broad-spectrum antibiotics were started for bacterial versus fungal sinusitis and the patient was admitted to the medical floor with consultations to Neurology, Otolaryngology (ENT), and Ophthalmology. ENT took the patient emergently to the OR. The final diagnosis was chronic aspergillus sinusitis and right-sided orbital apex syndrome (OAS). Antibiotics and antifungals were optimized by the infectious disease team. ENT also ordered steroid washouts post-operatively with budesonide and saline as well as sinus debridements every couple of weeks.

Brain metastases (BMs) related to cancer are quite common and represent the most common brain cancer. We present a rare case of a 32-year-old female, 36 weeks pregnant, admitted to the emergency with complaints of severe headache, vomiting, and left hemiparesis associated with drowsiness. Cranial tomography showed an image suggestive of an expansive lesion in the right front-temporo-insular region with an important mass effect. The result of biopsy with immunohistochemistry was compatible with metastasis of follicular thyroid carcinoma (FTC). The knowledge of neurological characteristics in the clinical analysis of patients with thyroid carcinoma must be highly valued, both in the correct interpretation of the signs and in the early investigation through skull imaging exams.

Preoperative opioid use is known to be detrimental to outcomes after total hip arthroplasty (THA). This is concerning as multiple societies recommend tramadol for the management of arthritis. The purpose of this study was to determine if tramadol is associated with postoperative complications, increased resource utilization, and revision when compared with patients receiving nontramadol opioids (NTOs) and those who are opioid naive (ON).

Metformin is the first-line treatment for any patient with type 2 diabetes. Metformin-associated lactic acidosis and transient blindness have only been reported in some case series and case reports. It is rare and presents especially in patients with underlying chronic kidney disease (CKD) Stage III and above and on high doses of metformin or with a normal dose of metformin and an associated renal injury. We present here a rare and interesting case of something similar. A 77-year-old woman with a past medical history of type 2 diabetes on metformin, obesity status post gastric bypass, CKD Stage III, presented with complaints of nausea, vomiting, confusion, abdominal pain, diarrhea, decreased urine output, sudden visual loss, and a hypoglycemic episode at home. She was hemodynamically stable. Lab work was suggestive of leukocytosis, hyperkalemia, severe high anion gap metabolic and lactic acidosis, acute-on-chronic kidney injury. Findings on the computed tomography (CT) brain, chest radiograph, and CT abdomen and pelvis could not explain the current scenario. She received Ringer's lactate, a bicarbonate push, and an infusion. Acidosis continued to worsen, she became hypotensive requiring pressor support, and she was immediately taken for hemodialysis. All her symptoms, including vision loss, had improved with a single session of hemodialysis, even before the acidosis had corrected. Work-up for other causes of renal dysfunction came back negative. Metformin was discontinued. She was placed on insulin for her diabetes control.

The new disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was dubbed coronavirus disease 2019 (COVID-19) by the World Health Organization and declared a pandemic. Initially thought to be a pathogen that primarily attacks the lungs, SARS-CoV-2 has turned out to be a much more formidable foe impacting almost every organ and system aggressively. I report the case of a 60-year-old man who came to the ED due to symptoms of high fever, headache, mild confusion, dry cough and exacerbated dyspnea since the last 24 hours. He had a history of idiopathic pulmonary fibrosis (IPF) and was undergoing treatment with antifibrotic medication. Apart from IPF, he had no other comorbid. He acquired SARS-CoV-2 infection by close contact and infection deteriorated into pneumonia and septic shock. Complete blood count showed white blood cells at 3.3×10/μL and platelets at 71×10/μL; lymphocyte count was low. Arterial blood gases revealed metabolic acidosis. Definitive diagnosis was by a positive real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens, and high-resolution computed tomography (HRCT) finding of new-onset ground-glass opacities on the very first day of admission that was the presenting day. The patient became unresponsive and died overnight. As numbers of COVID-19 show an uprise, this case highlights that IPF patients with relatively advanced age need to exercise extra caution because they are at high risk for developing overwhelming COVID-19-linked sepsis, which may be fatal.

Rheumatoid arthritis (RA) is an autoimmune disease characterised by systemic and chronic synovitis that lead to joint destruction, pain, and many complications. Treatments only relieve certain symptoms, but do not cure RA completely. Prostaglandins (PGs) are lipid signalling molecules and released in the early phase of RA. Increasing evidences have shown five main contribution of PGs to the different stages and symptoms of RA. First, PGs maintain the autoimmune response and immune-system inflammation by modulating the differentiation, maturation, and cytokine production of immune cells. Second, PGs are beneficial for leukocyte infiltration, synovial hyperplasia, and angiogenesis to promote synovitis. Third, PGs are involved in cartilage degradation and bone resorption. Fourth, PGs are important mediators of joint-pain regulation. Finally, in the late stage of RA inflammation, PGs play a part in joint protection. Those findings suggest that PGs are potential therapy targets for RA. This review highlights recent advances in the RA development caused by PGs, and provides recommendations for future research directions.
