ABSTRACT
The interactions between opioids and gabapentin are more clinically relevant than ever. Prescriptions dispensed for gabapentin increased from 39 million in 2012 to 64 million in 2018 in the USA and are ever increasing. Authors present a challenging case of these interactions. A 58-year-old man presented to the emergency department with acute respiratory failure and altered mental status. He was on high dose opioids and gabapentin as prescription medications. Despite full intensive care support and resolution of his respiratory failure with non-invasive positive pressure ventilation, the patient did not regain consciousness. After ruling out other causes, the diagnosis of gabapentin withdrawal was considered. Gabapentin was administered by a nasogastric tube that quickly resulted in a reversal of his symptoms. We concluded that severe gabapentin withdrawal should be considered in patients on higher doses of gabapentin when it is stopped abruptly. In such patients, gabapentin should be replaced. As most patients are unable to swallow in this situation and intravenous formulation is not available, nasogastric tube can be used for replacement.

Contrast nephropathy (CN) is acute kidney injury (AKI) that occurs within 24 to 72 hours of iodinated contrast medium (ICM) administration. Mechanisms of CN include hyperviscosity, free radical formation, and renal medullary oxygen supply/demand mismatch. Although risk factors for CN have been identified, it remains uncertain whether ICM causes or is simply associated with AKI. The cornerstones of CN prevention are using low-osmolal ICM, intravenous hydration, and statins, especially in patients with chronic kidney disease. With appropriate CN risk mitigation, coronary angiography and intervention should not be routinely withheld from patients with acute coronary syndromes.

SAPHO syndrome is a rare clinical entity composed of synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO). We describe a case of SAPHO syndrome masquerading as metastatic breast cancer in a patient with localized breast cancer who presented with cord compression. There was no pathologic evidence of metastatic cancer; however, a bone scan indicated osseous involvement. After multidisciplinary review of images and with additional findings of pustulosis and acne, a clinical diagnosis of SAPHO was made.
ABSTRACT
Bronchiolitis obliterans organising pneumonia as an initial manifestation of systemic lupus erythematosus (SLE) is a rare and uncommon presentation. We describe a case of SLE presenting with shortness of breath, found to have pneumothorax, bilateral nodular infiltrates along with pleural effusions and pericardial effusion. Work-up suggested a diagnosis of active SLE with anaemia, thrombocytopenia, positive antinuclear antibodies (ANAs) and positive anti-double-stranded DNA. On retrospective review of patient records, from 8 years prior to presentation, lung biopsy histology consistent with bronchiolitis obliterans organising pneumonia with positive ANA serology was found, without any further autoimmune work-up. In our opinion, bronchiolitis obliterans organising pneumonia was the index presentation of SLE. Treatment with steroids and subsequent management with immunosuppressive therapy could have prevented subsequent hospitalisations. Prompt work-up for autoimmune diseases should be considered in patients with positive ANA and histological evidence of bronchiolitis obliterans organising pneumonia.

Olmesartan (brand name Benicar) is an antihypertensive drug clinicians commonly use to treat high blood pressure. Olmesartan induced enteropathy (OSE) is a rare entity that authors first identified in 2012. The etiological basis of OSE remains unclear, although authors have suggested that this condition could be due to alternations in cell mediated immune responses induced by the drug. The objective of the case report is to describe a patient who presented with diarrhea and was eventually diagnosed with OSE. A female patient in her later 60s presented to an emergency room after two recent hospitalizations with profound diarrhea, generalized weakness and weight loss. She underwent a diagnostic workup including endoscopy and colonoscopy. The patient's endoscopy with duodenal biopsy revealed villous atrophy with attenuated and blunted villi with intraepithelial CD3 positive T lymphocytes, suggestive of gluten-induced enteropathy. When the patient's symptoms did not improve after the authors placed her on a gluten free diet for a few days, they further investigated her for secretory diarrhea, including Gastrin, Somatostatin and Vasoactive Intestinal Peptide lab values that they found to be within normal limits. Due to the patient's lack of improvement with initial treatment, the authors suspected OSE and stopped her olmesartan and the patients' symptoms gradually improved in three weeks.
