Evaluation of Monkeypox as an Unrecognized Sexually Transmitted Disease: A Rare Case of Monkeypox Infection with HIV and Syphilis Coinfection.

Monkeypox (MPX) virus is endemic in Africa. However, since May 2022, many cases have been reported worldwide in many non-endemic regions as well. The virus usually spreads from animals to humans or from humans to humans through respiratory droplets or after contact with infected lesions. In the recent outbreak of MPX, many cases did not have any travel history to endemic areas and were reported in men who have sex with men (MSM) along with the diagnosis of other sexually transmitted diseases (STDs). However, MPX is not yet considered a sexually transmitted infection (STI), even though a relationship between MPX and other STIs may exist with a possible facilitating action on their spreading. We present a similar case of MPX infection in an MSM patient with concomitant HIV and syphilis infections and no travel history to an endemic area.

A Meta-analysis of the Severity of Acute Pancreatitis (AP) in COVID-19 Infection.

Many studies have reported severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affecting the gastrointestinal tract and causing gastritis, colitis, duodenitis and acute pancreatitis (AP). We conducted a meta-analysis to evaluate if SARS-CoV-2 infection (COVID-19 infection) affects the outcomes and severity of AP. We searched for articles in PubMed (MEDLINE), Cochrane Library, and clinicaltrials.gov databases and included studies comparing the outcomes of AP in patients with and without COVID-19. Our outcomes were the mean age of occurrence of AP, Charlson Comorbidity Index, incidence of idiopathic etiology of AP, severity of AP, incidence of necrotizing pancreatitis, need for intensive care unit (ICU) admission, and mortality between the two cohorts. We included five observational studies with a total population of 2,446 patients. Our results showed that in COVID-19 patients; AP had higher odds of having an idiopathic etiology (odds ratio, OR 3.14, 95% confidence interval, CI 1.36-7.27), be more severe (OR 3.26, 95% CI 1.47-7.49), had higher risk for pancreatic necrosis (OR 2.40, 95% CI 1.62-3.55), require ICU admission (OR 4.28, 95% CI 2.88-6.37) and had higher mortality (OR 5.75, 95% CI 3.62-9.14) than in patients without COVID-19 infection. Our study concluded that SARS-CoV-2 infection does increase the morbidity and mortality associated with AP and further large-scale multi-center studies are needed to confirm these results.

The Role of Transcatheter Aortic Valve Replacement in Asymptomatic Aortic Stenosis: A Feasibility Analysis.

Surgical aortic valve replacement (SAVR) is the current treatment of choice for good surgical candidates with moderate to severe symptomatic aortic stenosis (AS). As transcatheter aortic valvular replacement (TAVR) has shown an improved one and two-year all-cause mortality, it has been chosen for moderately symptomatic severe AS patients. The purpose of this review was to perform a clinical comparison of TAVR vs. SAVR and to analyze the Health Index Factor (HIF) that makes TAVR a treatment of choice in asymptomatic AS patients.  An extensive literature search of PubMed, Cochrane, and Embase databases was performed using the keywords "Aortic stenosis", "SAVR", "TAVR", and "Asymptomatic". A total of 45 prospective randomized clinical trials in the English language that were published from the year 2000 onwards were included in the final analysis. It has been found that 59.3% of asymptomatic AS patients are likely to die in the next five years without proactive treatment. Multiple studies have proven that early intervention with aortic valve replacement is superior to conservative treatment in severe asymptomatic AS; however, the choice between SAVR and TAVR is not well established. The NOTION Trial, SURTAVI Trail, and PARTNER 3 study have shown the non-inferiority of TAVR over SAVR, during one-year follow-up for low surgical risk patients. Evolut Low-Risk study and Early TAVR are the only two prospective studies performed to date that have enrolled patients with asymptomatic severe AS. The Evolut Trial demonstrated no difference in all-cause mortality at 30 days (1.3% vs. 4.8%. p=0.23), and 12 days (1.3% vs. 6.5%, p=0.11). Additionally, TAVR also decreases the risk of post-procedural atrial fibrillation, acute kidney injury (AKI), and rehospitalization, and leads to significant improvement in the mean trans-aortic pressure gradient. TAVR also showed marked improvement in the 30-day Quality of Life (QOL) index, where SAVR did not report any significant change in the QOL index. However, the official recommendations of Early TAVR are still awaited. TAVR has consistently shown a statistically non-significant difference in case mortality, risk of stroke, and rehospitalization with moderate to high surgical risk patients whereby recent initial trials have shown significant improvement in the QOL index and hemodynamic index for patients with asymptomatic disease. More extensive studies are required to prove the risk stratifications, long-term outcomes, and clinical characteristics that would make TAVR a preferred intervention in asymptomatic patients.

Acute Pancreatitis Related to COVID-19 Infection: A Systematic Review and Analysis of Data.

There is increasing literature mentioning severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19 infection) causing acute pancreatitis (AP). It is hypothesized that SARS-Cov-2 causes pancreatic injury either by direct cytotoxic effect of the virus on pancreatic cells through the angiotensin-converting enzyme 2 (ACE2) receptors - the main receptors for the virus located on pancreatic cells - or by the cytokine storm that results from COVID-19 infection or a component of both. Many viruses are related to AP including mumps, coxsackievirus, cytomegalovirus (CMV), Epstein-Barr virus (EBV), and as data evolves SARS-CoV-2 virus may be one of them as well. We conducted a systematic literature review to explore the current literature and provide an overview of the evidence of AP in COVID-19 infection. We studied the presence of AP in patients with SARS-CoV-2 infection and calculated the time of diagnosis of SARS-CoV-2 infection with respect to the time of diagnosis of AP. We also studied the age, gender, clinical manifestations, time of onset of symptoms, laboratory values, imaging findings, mortality, length of stay, comorbidities, need for Intensive Care Unit (ICU) care, and excluded any other common causes of AP. We included 40 articles comprising 46 patients. All patients had a positive SARS-CoV-2 polymerase chain reaction (PCR) test and all patients had AP as per Atlanta's criteria. The most common clinical presentation was abdominal pain in 29 (63.0%). Edematous pancreas was the most common Computed Tomography Abdomen Pelvis (CTAP) scan finding in these patients (35 patients). Seventeen (37%) patients required ICU admission and six (13%) patients died. Our study provides an important overview of the available data on AP in COVID-19 patients and concludes that AP is an important complication in COVID-19 infection and should be considered as an important differential in patients with COVID-19 infection who complain of abdominal pain.

Pelvic Irradiation: A Rare Cause of Concomitant Radiation Cystitis and Uretero-Iliac Artery Fistula Causing Gross Hematuria and Hemorrhagic Shock.

Uretero-iliac artery fistulas (UIAFs) are a rare cause of gross hematuria. They form as a result of poorly vascularized uretero-iliac adhesions and the resultant fibrosis and chronic inflammatory changes. Causes include previous pelvic surgery, radiotherapy, and chronic ureteral stenting. The presentation is usually intermittent massive gross hematuria with acute anemia and hemorrhagic shock. A high index of suspicion is warranted in patients with predisposing factors for prompt diagnosis and management as it may be associated with life-threatening hemorrhage. Due to the intermittent nature of symptoms, identification is not always apparent. Open surgical repair was the treatment of choice in the past. With advancements in interventional radiology techniques, endovascular stenting of the iliac artery and concomitant ureteral stenting is the current treatment of choice. We report a case of massive gross hematuria leading to hemorrhagic shock with underlying UIAF and predisposing risk factor of pelvic irradiation. Our case report describes the diagnostic challenges with associated comorbid conditions causing delays in successful management.

Inappropriate Subcutaneous Implantable Cardioverter Defibrillator Shocks Secondary to Cardiac Remodeling: A Unique Case of T Wave Oversensing.

Implantable cardioverter defibrillators (ICD) are used for the primary and secondary prevention of sudden cardiac death (SCD). Currently, two different modalities of ICDs are in use: transvenous (TV) and subcutaneous (S-ICD). The use of S-ICDs has been driven by several potential benefits of this technology: preservation of central venous vasculature, no risk of vascular or myocardial injury during implant, easier explanation, and lower risk of systemic infections. Inappropriate shocks are defined as shocks delivered for non-life-threatening arrhythmias or because of oversensing. Here, we present a case of a 58-year-old man who began experiencing inappropriate shocks three years after S-ICD placement. Careful analysis of the ICD showed T wave oversensing with no malfunction of the device. The shocks persisted even after reprogramming, leading to subsequent ICD removal and loop recorder implantation. The onset of shock episodes coincided with the improvement of left ventricular ejection fraction (LVEF). To the best of our knowledge, this is the first published report of cardiac remodeling leading to uncorrectable T wave oversensing that subsequently required S-ICD explant. This represents a potentially important limitation of S-ICD technology, especially as S-ICD use rises and medical therapy for cardiomyopathy continues to improve.

Severe Pulmonary Artery Hypertension in Otherwise Silent Lupus: A Unique Hybrid Treatment Approach Using Hydroxychloroquine and Sildenafil.

Pulmonary hypertension (PH) is a rare manifestation of systemic lupus erythematosus (SLE). Even more rare is pulmonary artery hypertension (PAH) presenting as the initial manifestation of SLE and may be a cause of diagnostic delay. As symptoms of PAH are very mild in the early stages, prompt diagnosis is crucial to prevent the progression of the disease. Echocardiographic evaluation involving the measurement of different right-sided heart variables in addition to estimated pulmonary artery pressure helps in reducing the false-positive rates of detection of PAH. The role of immunosuppression in addition to PAH-specific vasodilator therapy is one of the key aspects of management to minimize flares and improve hemodynamics. Equally important is the choice of a regimen best suited to minimize complications. We present a case of PAH in newly diagnosed SLE and the diagnostic and treatment challenges as a safety net hospital.

Interventional Dilemma in a Young Woman With Spontaneous Coronary Artery Dissection Who Presented With High-Risk Non-ST-Elevation Myocardial Infarction (NSTEMI) Progressing to ST-Elevation Myocardial Infarction (STEMI).

Spontaneous coronary artery dissection (SCAD) is an infrequent presentation of acute myocardial infarction in young women and denotes the non-atherosclerotic separation of the coronary artery wall. Precipitating causes include fibromuscular dysplasia, postpartum hormonal changes, multiparity, connective tissue diseases like Marfan syndrome, autoimmune conditions, and hormonal therapy. It is often underdiagnosed due to a low index of suspicion based on age and gender bias as well as knowledge about different angiographic variants in SCAD. Intracoronary imaging with optical coherence tomography (OCT) or intravascular ultrasound (IVUS) is used for patients where coronary angiography fails to secure a diagnosis to increase the diagnostic yield. The mainstay of stable SCAD is conservative management. However, there are no definitive guidelines due to limited clinical experience. Treatment involving percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), fibrinolytic therapy, and mechanical hemodynamic support should be individualized depending upon clinical presentation, type, and extent of dissection, hemodynamic instability, critical anatomy involvement, and the extent of ischemic myocardium. We are presenting a case of a young female who presented with non-ST-elevation myocardial infarction (NSTEMI) that progressed to ST-elevation myocardial infarction (STEMI). A coronary angiogram showed a tortuous left anterior descending artery (LAD) with a distal 100% occlusion due to SCAD. PCI was attempted but the guidewire could not be navigated intraluminally past the occlusion. CABG was not pursued due to the distal location of the occlusion and lack of visualization of the distal vessel. Our case provides a useful learning opportunity for physicians who may come across similar clinical presentations. In patients with high-risk features of SCAD who are deemed inoperable, timely and appropriate medical management may be a useful alternative for PCI/CABG and the recurrence rates of SCAD are very low.

A Diagnostically Challenging Parotid Gland Tumor With Hybrid Features.

Salivary gland tumors are relatively uncommon with most being benign. When diagnosed the most common benign and malignant tumors are pleomorphic adenoma and mucoepidermoid carcinoma (MEC), respectively. However, not uncommonly, it is difficult to differentiate between the histopathological entities, leading to a diagnostic dilemma that can impact a patient's treatment and prognosis. A 24-year-old woman presented with a three-year history of asymptomatic left-sided facial swelling. She denied any prior history of head and neck radiation. There was no history of alcohol consumption or smoking exposure and there was no personal or family history of head and neck cancers. Additionally, she did not have any known occupational or environmental exposures. Due to the chronicity and painless nature of this facial mass, our patient did not pursue evaluation initially. Subsequently, she experienced an increase in size and pain for a few months exacerbated by swallowing. She had no other symptoms. On physical examination, a 3 x 3 cm left parotid gland mass was noted. There was no associated head or neck lymphadenopathy and compression of the left facial mass did not elicit secretions from the opening of Stensen's duct. Due to the rapid increase in size, she was sent for CT neck/soft tissue with contrast which confirmed a 3.56 x 2.67 cm solid nodule within the superficial portion of the left parotid gland. This was followed by an MRI orbit/face/neck with and without contrast, for further delineation, which demonstrated a 4 x 3.7 x 3 cm complex heterogeneous mass within the superficial left parotid gland. Thereafter the patient underwent an uncomplicated ultrasound-guided biopsy of the parotid mass. The histopathological appraisal concluded that this was a cellular pleomorphic adenoma, with mucinous and squamous metaplasia with reactive lymph nodes. Due to the new rapid increase in size and intense painful nature of this tumor, nerve-sparing left parotidectomy, fat grafting and reconstruction were completed. Cellular pleomorphic adenomas are benign low-grade neoplasms, typified as biphasic with both epithelial and myoepithelial components. However, they have increased cellularity and focally increased mitotic activity, not advanced enough to qualify as malignant. The presence of mucinous and squamous metaplasia is of diagnostic interest as it makes diagnosis on fine-needle aspiration (FNA) morphologically challenging. These findings are typical of MEC and on FNA can be misleading in the setting of a pleomorphic adenoma. However, on histopathological evaluation of the gross specimen along with immunohistochemical staining the diagnosis is made much easier. A diagnosis of MEC would have potentially required neck dissection and adjuvant therapy with a potential increased risk of morbidity and mortality. This case emphasises the importance of an adequate tissue biopsy in regards to parotid gland tumors to optimise a patient's care plan.

Clinical Presentation, Diagnosis, and Management of Air Embolism During Endoscopic Retrograde Cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive procedure that is widely used by endoscopists and has a robust therapeutic profile. It uses endoscopy and imaging for a variety of diagnostic as well as therapeutic purposes. It is used for the management of a lot of pancreaticobiliary diseases such as obstructive jaundice, obstruction related to bile ducts, pancreatic biliary tumors, and traumatic or iatrogenic damage to the bile ducts. Other therapeutic interventions that can be done via ERCP include sphincterotomy, dilation of strictures, removal of biliary stones and placement of stents. Air embolism presents with cardiovascular, pulmonary, and neurologic signs and symptoms. Treatment of air embolism should be started early in suspected cases, and it should be in the differential diagnoses of various complications secondary to high risk of ERCP, especially if a cardiopulmonary compromise is present. Air embolism is rare but a serious complication associated with ERCP. The physicians must keep this in mind while performing ERCP in patients with predisposing risk factors. This review highlights the mechanism, causes, risk factors, pathophysiology, clinical signs, diagnostic modalities, treatment, and preventive measures to deal with this catastrophic complication.
