Prevalence and factors associated with inappropriate continuation of stress ulcer prophylaxis at discharge.

Stress ulcer prophylaxis is started in the critical care unit to decrease the risk of upper gastrointestinal ulcers in critically ill persons and to decrease mortality caused by stress ulcer complications. Unfortunately, the drugs are often continued after recovery through discharge, paving the way for unnecessary polypharmacy. STUDY DESIGN: We conducted a retrospective cross-sectional study including patients admitted to the adult critical care unit and started on the stress ulcer prophylaxis with a proton pump inhibitor (PPI) or histamine receptor 2 blocker (H2 blocker) with an aim to determine the prevalence of inappropriate continuation at discharge and associated factors. RESULT: 3200 people were initiated on stress ulcer prophylaxis, and the medication was continued in 1666 patients upon discharge. Indication for long-term use was not found in 744 of 1666, with a 44% prevalence of inappropriate continuation. A statistically significant association was found with the following risk factors: discharge disposition (home vs other medical facilities, p=0.002), overall length of stay (more than 10 days vs less than or equal to 10 days, p<0.0001), mechanical ventilator use (p<0.001), number of days on a mechanical ventilator (more than 2 days vs less than or equal to 2 days, p<0.001) and class of stress ulcer prophylaxis drug used (H2 blocker vs PPI, p<0.001). CONCLUSION: The prevalence of inappropriate continuation was found to be higher than prior studies. Given the risk of unnecessary medication intake and the associated healthcare cost, a web-based quality improvement initiative is being considered.

A Rare Case of Peritoneal Dialysis-Associated Peritonitis Caused by Neisseria sicca.

Peritonitis is a critical complication in peritoneal dialysis, often leading to peritoneal dialysis (PD) treatment failure. We present a rare case of Neisseria sicca (NS)-related peritonitis in a 47-year-old male with multiple comorbidities. Despite NS's infrequent association with infections, prompt diagnosis and antibiotic therapy based on International Society for Peritoneal Dialysis (ISPD) guidelines led to a favorable outcome. This case emphasizes identifying uncommon pathogens in immunocompromised individuals and highlights the importance of prompt treatment to prevent morbidity.

Spinal Solitary Plasmacytoma With Minimal Marrow Involvement Presenting With Epidural Spinal Cord Compression.

Solitary plasmacytoma (SPC) is a rare type of plasma cell dyscrasia characterized by the proliferation of neoplastic monoclonal plasma cells. It can involve bone or soft tissue without signs of systemic disease. The solitary bone plasmacytoma typically involves the axial skeleton, most commonly the vertebrae. This article presents a 58-year-old male with a history of Parkinson's disease, hypertension, and cervical spine degenerative joint disease. He arrived at the emergency department with severe thoracic and lumbar back pain, accompanied by numbness and weakness in both legs, which worsened with movement and deep breathing. Magnetic resonance imaging (MRI) findings revealed a sizable mass in the T11 vertebra, leading to thoracic spinal cord compression. Treatment included high-dose dexamethasone, and surgical intervention was undertaken. Subsequent pathology confirmed plasma cell dyscrasia. Radiotherapy and chemotherapy (lenalidomide and dexamethasone) were administered, resulting in no recurrence or new masses after two years. Solitary plasmacytoma is a rare disease with limited clinical trials due to the inability to accrue larger cohorts. Prompt diagnosis and staging of plasmacytomas, involving robust histopathological and radiographic methods, are needed to prevent further complications and possible progression to multiple myeloma. Radiation therapy is the primary treatment, with some studies showing the benefits of lenalidomide and dexamethasone. Further studies are needed to improve treatment options for these patients. This case report adds to the current literature the importance of a multidisciplinary approach to the treatment of SPC.

Hemophagocytic Lymphohistiocytosis: A Rare Complication of COVID-19 in a Patient With Sickle Cell Anemia.

Hemophagocytic lymphohistiocytosis (HLH) is an uncommon condition that can be fatal due to overwhelming macrophage activation and cytokine production. It can be primary (familial/genetic) or secondary. It is associated with infections, malignancies, and rheumatologic and immunodeficiency disorders. We report a middle-aged female patient with sickle cell anemia who presented with COVID-19 infection that triggered a vaso-occlusive crisis and resulted in HLH. She had preexisting high ferritin levels and cytopenias, making the diagnosis more challenging. A high index of suspicion and timely treatment is essential to prevent adverse outcomes.

Immune Reconstitution Inflammatory Syndrome in Aids Patient After Successful Induction of Virological Suppression with Cabotegravir/Rilpivirine.

Long-acting (LA) cabotegravir/rilpivirine (CAB/RPV) is a complete regimen for the management of human immunodeficiency virus type 1 (HIV-1) infection to replace their oral antiretroviral therapy (ART) when they have been virologically suppressed. We present a case of successful achievement of undetectable HIV RNA viral load levels in an acquired immunodeficiency syndrome (AIDS) patient with long-standing virologic failure within two months of CAB/RPV LA initiation. This was later complicated by immune reconstitution inflammatory syndrome (IRIS) due to Mycobacterium avium-intracellulare (MAI) infection and hepatitis B virus (HBV) reactivation. LEARNING POINTS: This case highlights the efficacy of monthly CAB/RPV LA in rapidly reducing the HIV viral load level in a poorly controlled patient who lacked significant resistance to the two drugs.This is the first case of IRIS reported in the literature while using CAB/RPV LA. IRIS in the setting of occult MAI is well recognised. It would have occurred with good adherence to any regimen which rapidly suppressed the viral load and is unlikely to be due to CAB/RPV. CAB/RPV has no activity against HBV, which may have contributed to its reactivation.The patient had serologic evidence of resolution of prior HBV. However, some patients have covalently closed circular DNA (cccDNA) that may remain long term in hepatocyte nuclei.

Incidental Finding of Riedel's Lobe of the Liver and Intrahepatic Cholangiocarcinoma.

Riedel's lobe is a rare anatomical variant of the liver morphology with a downward tongue-like projection of the anterior edge of the right lobe. It is usually detected incidentally with abdominal imaging performed for other indications. We present a case where we found Riedel's lobe incidentally, with invasive adenocarcinoma arising from close proximity. A 64-year-old female came in with encephalopathy and was found to have a distended abdomen with tenderness. Imaging revealed a complex lobular mass in the right hepatic lobe with an elongated extension of the right lobe inferiorly consistent with Riedel's lobe. The differential considered was malignancy versus abscess. CT-guided biopsy revealed invasive adenocarcinoma consistent with intrahepatic cholangiocarcinoma, which was further supported by the presence of portocaval lymph nodes. Various studies have tried to establish an association between Riedel's lobe and the occurrence of cancer arising from the surrounding structures, primarily from liver or metastasis. This case report adds to the current literature when such an association is being studied.

Code Pseudo Stroke - A Case of Hypokalaemic Periodic Paralysis Mimicking Stroke.

We present a case of thyrotoxic periodic paralysis (TPP) presenting with stroke symptoms as a harbinger of Grave's disease. A 61-year-old female presented with symptoms of abdominal pain and fatigue two weeks prior to admission and reported acute diarrhoea and unintentional weight loss. Investigation revealed thyrotoxicosis with undetectable thyroid stimulating hormone (TSH), elevated free T4 and elevated thyroid stimulating immunoglobulin (TSI). On the third day of admission, while undergoing physical therapy, code stroke was called on account of the onset of right-side predominant acute flaccid paralysis of upper and lower extremities, right-side facial droop, dysarthria and hyporeflexia bilaterally. The patient was alert and fully oriented with stable vitals with no increased labour in breathing at room air. An emergent head and neck CT, angiography, and magnetic resonance imaging (MRI) were negative. Serum potassium was 2.7 mmol/l, requiring prompt replacement. The patient's paralysis and dysarthria improved over the following three days with a complete reversal of symptoms following the correction of serum potassium. Thyrotoxic periodic paralysis can occur in association with any of the causes of hyperthyroidism. It is due to a significant intracellular shift of potassium, subsequently manifesting clinically with hypokalaemia and muscle paralysis. LEARNING POINTS: Hypokalaemic periodic paralysis is an acute flaccid paralysis secondary to hypokalaemia, triggered by hyperthyroidism, environmental elements such as a high carbohydrate intake or rest after intense exercise, and an underlying genetic component with mutations in the muscle ion channels.The pursuit of code stroke protocol in the in-patient setting must bear in mind reversible but potentially fatal and disabling alternative diagnoses such as stroke mimics including hypokalaemic periodic paralysis.Stroke mimics defined as acute onset neurological deficits that are not related to vascular cause are a true challenge, multiple scales have been created to distinguish them from an actual stroke, such as the Recognition of Stroke in the Emergency Room (ROSIER) scale.

Antimitochondrial Antibody-Negative Primary Biliary Cholangitis: A Retrospective Diagnosis.

Primary biliary cholangitis (PBC) is an inflammatory cholestatic disease that tends to worsen, leading to hepatic cirrhosis and portal hypertension. We present a case of a middle-aged female who presented with progressively worsening generalized itch; the examination was significant only for urticarial rash and facial swelling. Investigation revealed direct hyperbilirubinemia, mildly elevated transaminase, and significant elevation of alkaline phosphatase. A differential was performed with labs including antimitochondrial antibodies (AMA) for PBC, hepatitis panel, anti-smooth muscle antibodies for autoimmune hepatitis, and tissue transglutaminase IgA for celiac disease, all of which were unremarkable. The patient was empirically treated with ursodeoxycholic acid (UDCA). Given the excellent clinical response at the three-week follow-up to treatment despite negative AMA, further testing with anti-sp100 and anti-gp210 was pursued, which returned positive for anti-sp100, confirming the diagnosis of PBC.
