Direct percutaneous endoscopic jejunostomy (DPEJ) and percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) technical success and outcomes: Systematic review and meta-analysis.

Background and study aims Endoscopic methods of delivering uninterrupted feeding to the jejunum include direct percutaneous endoscopic jejunostomy (DPEJ) or PEG with jejunal extension (PEG-J), validated from small individual studies. We aim to perform a meta-analysis to assess their effectiveness and safety in a variety of clinical scenarios. Methods Major databases were searched until June 2021. Efficacy outcomes included technical and clinical success, while safety outcomes included adverse events (AEs) and malfunction rates. We assessed heterogeneity using I 2 and classic fail-safe to assess bias. Results 29 studies included 1874 patients (983 males and 809 females); mean age of 60 ±â€Š19 years. Pooled technical and clinical success rates with DPEJ were 86.6 % (CI, 82.1-90.1, I 2 73.1) and 96.9 % (CI, 95.0-98.0, I 2 12.7). The pooled incidence of malfunction, major and minor AEs with DPEJ were 11 %, 5 %, and 15 %. Pooled technical and clinical success for PEG-J were 94.4 % (CI, 85.5-97.9, I 2 33) and 98.7 % (CI, 95.5-99.6, I 2  < 0.001). The pooled incidence of malfunction, major and minor AEs with DPEJ were 24 %, 1 %, and 25 %. Device-assisted DPEJ performed better in altered gastrointestinal anatomy. First and second attempts were 87.6 % and 90.2 %. Conclusions DPEJ and PEG-J are safe and effective procedures placed with high fidelity with comparable outcomes. DPEJ was associated with fewer tube malfunction and failure rates; however, it is technically more complex and not standardized, while PEG-J had higher placement rates. The use of balloon enteroscopy was found to enhance DPEJ performance.

Serotonin Surge: Intravenous Escitalopram as a Rare Cause of Drug-Induced Aplastic Anaemia.

Escitalopram is a commonly prescribed medication that has infrequently been implicated in drug-induced thrombocytopenia (DITP) but has never been associated with aplastic anaemia in the literature. We present an extremely rare case of hypoproliferative pancytopenia due to self-administered intravenous (IV) injection of escitalopram. The crux of this case is the unusual trilineage cytopenia. Our patient was managed with steroids and supportive care with subsequent clinical and blood count recovery. This case sheds light on this uncommon but important association. LEARNING POINTS: Escitalopram is an uncommon medication that could lead to drug-induced aplastic anaemia.The adverse effects of escitalopram on red cell, white cell and platelet counts may be exacerbated on intravenous administration of the medication.Timely diagnosis is vital for the effective treatment of severe aplastic anaemia, avoiding complications and preventing recurrence.

Refractory familial hypokalaemic periodic paralysis leading to cardiovascular compromise.

Familial hypokalaemic periodic paralysis (FHPP) is a rare neuromuscular disorder that is classified under periodic paralysis (PP), which is characterised by episodes of muscle weakness. Common triggers include intense exercise, fasting or consumption of carbohydrate-rich meals. Hypokalaemic PP has an incidence of 1 in 100 000; despite the temporal association, cardiac manifestations are exceedingly rare. We present a case of FHPP, a channelopathy presenting with severe refractory hypokalaemia. The challenges with our patient were maintaining potassium levels within normal ranges and initiating a close follow-up plan. Due to the lack of clinical guidance in our case, many aspects of care, including surveillance, medications and genetic testing, remain unaddressed. Medical management includes aggressive correction with supplements, potassium-sparing diuretics and carbonic anhydrase inhibitors. Severe cases of dysrhythmias, especially ventricular fibrillation, require electrophysiology evaluation and possible implantation of a defibrillator to prevent sudden cardiac death.

Proton Pump Inhibitors Versus Histamine-2-Receptor Antagonists for Stress Ulcer Prophylaxis in Critically Ill Patients: A Meta-analysis and Trial Sequential Analysis.

GOALS AND BACKGROUND: Stress ulcer prophylaxis has been shown to lower gastrointestinal bleeding (GIB) rates. Various agents have been studied, and the optimal strategy continues to be contested. This study evaluates the efficacy between proton pump inhibitors (PPIs) and histamine-2-receptor antagonists. Small sample sizes and methodology flaws limited prior studies. STUDY: A systematic search of MEDLINE, EMBASE, CENTRAL, Web of Science, and ClinicalTrials.gov for randomized controlled trials reporting the use of PPI and histamine-2-receptor antagonist reporting rates of GIB and standardized intensive care outcomes. Risk ratios (RR) and standardized mean difference (SMD) with 95% confidence intervals (CIs). A trial sequential analysis was performed to guard against errors. RESULTS: A total of 14 randomized controlled trials of 28,526 patients with a mean age of 57.83±17.35 years and 30.82% females. In our pooled analysis, PPI outperformed its comparator (RR: 0.68; 95% CI: 0.57-0.82) in clinically significant GIB. PPI re-demonstrated significant reduction in overt GIB (RR: 0.61; 95% CI: 0.39-0.97). No differences between groups was noted toward all-cause mortality (RR: 1.05; 95% CI: 1.00-1.10) or incidence of pneumonia (RR: 1.11; 95% CI: 0.82-1.51). Duration of stay (SMD: 0.07; 95% CI: -0.04-0.17) and ventilator days (SMD: 0.01; 95% CI: -0.01-0.04) were indifferent between the groups. CONCLUSIONS: Among critically ill patients, PPI was associated with reduced clinically significant or overt GIB. No differences in pneumonia were seen with the use of either agent. Trial sequential analysis for clinically significant GIB ruled out the risk for false-positive results, and thereby it is unlikely that future trials will affect our conclusions.

Black oesophagus, upside-down stomach and cameron lesions: cascade effects of a large hiatal hernia.

Acute oesophageal necrosis, black oesophagus (BE) or Gurvits syndrome (GS) is a rare form of severe oesophagitis appearing as a striking circumferential discolouration of distal mucosa with various proximal extensions abruptly terminating at the gastro-oesophageal junction. It is most commonly associated with acute exacerbations of medical comorbidities, while associations with altered gut anatomy are rare. We present a unique constellation of BE, Cameron ulcers (CU), and gastric volvulus from a large paraesophageal hiatal hernia. Our patient recently recovered from COVID-19 and was malnourished and frail, while the expanding paraesophageal hiatal hernia turned into an acute organoaxial gastric volvulus with accompanying outlet obstruction. In low-flow post-COVID coagulopathic states, compensatory mechanisms may lack against gastric stunning and sudden massive reflux on the oesophagus. We additionally performed a systematic review and discovered additional cases with coexistent volvulus and paraesophageal hernia, although there are no previous reports of BE with CU, which makes this study the first.

When Variants Collide: An Unusual Presentation of Metastatic Gastric Mixed Neuroendocrine-Non-Neuroendocrine Neoplasm.

Gastrointestinal neuroendocrine neoplasms were recently reclassified into the 2019 World Health Organization schema into well-differentiated neuroendocrine tumors, poorly differentiated neuroendocrine carcinomas, and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs). Among these, gastric MiNENs are exceedingly rare and often metastasize quickly without diagnostic clues. We present a refractory gastric MiNEN with unique presenting features. This case highlights the clinical spectrum of these tumors, the importance of accurate histochemical interpretation, and clinical management in the absence of formalized guidelines. Future therapies looking at novel targets and palliative symptom relief are needed.

Accelerated balloon-retrograde transvenous obliteration (BRTO): an effective tool in the Arsenal against isolated gastric varices (IGV).

Gastric and oesophageal variceal bleeding poses high morbidity and mortality in cirrhosis. Amongst all types, isolated gastric varices (IGV) carry the highest propensity to bleed. Successful outcomes combine endoscopic and interventional radiology approaches using ligation, coils, glue or sclerosants. Transjugular intrahepatic portosystemic shunt success is only seen in a subset of patients, while balloon-retrograde transvenous obliteration (BRTO) has demonstrated high efficacy in preventing rebleeding and morbidity in patients with a myriad of anatomies and shunts. The American Association for the Study of Liver disease guidelines do not favour any particular modality; however, recent trials and meta-analyses support BRTO as the first-line therapy. Despite promising results, BRTO adoption is limited by procedural time, patient length-of-stay and equipment compatibilities hindering scalability in academic and community settings. To address these concerns, we present a successfully treated case of IGV with a revised technique called accelerated BRTO.

Sarcoidosis Masquerading as Long-Standing Cholestasis.

Hepatic sarcoidosis is an exceedingly rare extrapulmonary manifestation of sarcoidosis, with the majority remaining stable for years without clinical clues, only displaying biochemical abnormalities. Amongst the literature, the timeline to cirrhosis has not been parsed out; hepatomegaly develops in 50% and cirrhosis in 33% of all hepatic sarcoidosis patients, making this an essential issue in this patient population. Interestingly, the risk for hepatocellular carcinoma remains high regardless of cirrhosis development. Corticosteroids and biologics remain the mainstay of therapy, although refractory cases may require deeper immunosuppression. Liver transplantation is seen in a handful of cases with promising results. We present an interesting case of cholestatic pattern livery injury in our outpatient setting that was eventually discovered to be hepatic sarcoidosis. Mild biochemical derangements or sole elevations in alkaline phosphatase are under-recognized, and patients often progress to cirrhosis and end-stage liver disease. This diagnostic miss has significant implications and represents an opportunity to treat liver disease with a reversible cause. Consensus guidelines recommend alkaline phosphatase screening in newly diagnosed cases of sarcoidosis.

Serrating through vascular access catheters: a great masquerader with severe systemic manifestations.

Serratia marcescens, time and again, has demonstrated its ability to easily adhere and infect vascular access catheters, making them a bona fide source of hospital outbreaks and contributing to adverse patient outcomes. We present a unique case of a severe recurrent Serratia infection, leading to persistent bacteria in the blood, haematogenous dissemination and subsequent development of abscesses, to a degree not reported in the literature before. These infections are exceedingly challenging to eradicate, owing to multiple virulence mechanisms and the deep seeding ability of this microorganism. Serratia infections require a multifaceted approach with intricacies in identification, therapeutics and surveillance, all of which are sparsely reported in the literature and reviewed in this report.

Pericardial effusion uncovering underlying hypothyroidism.

Pericardial effusion may be the tipping point to unravel hypothyroidism. Large effusions may not correlate with severity of cardiovascular compromise. Medical therapy over surgical intervention is appropriate if no evidence of cardiac tamponade.

An Enigmatic Elevation of Troponin in a Patient With Seizures.

A 64-year-old African American male, with past medical history of hypertension, depression, and seizure disorder, presented with an episode of generalized tonic-clonic seizure. He was treated for seizures, and after 48 hours seizure-free, the patient started complaining of chest tightness and troponin levels were found to be 34.71 ng/mL. No evidence of myocardial infarction was found after extensive diagnostic workup, including cardiac catheterization. We suspect alternative causes of elevated troponin including post-seizure and transient takosubo cardiomyopathy.

Acute confusional state as a prognostic sign of COVID-19 large-vessel occlusion (LVO).

COVID-19 is well known for its respiratory symptoms, but severe presentations can alter haemostasis, causing acute end-organ damage with poor outcomes. Among its various neurological presentations, cerebrovascular events often present as small-vessel strokes. Although uncommon, in predisposed individuals, large-vessel occlusions (LVOs) can occur as a possible consequence of direct viral action (viral burden or antigenic structure) or virus-induced cytokine storm. Subtle presentations and complicated stroke care pathways continue to exist, delaying timely care. We present a unique case of COVID-19 LVO manifesting as an acute confusional state in an elderly man in April 2020. CT angiography revealed 'de novo' occlusions of the left internal carotid artery and proximal right vertebral artery, effectively blocking anterior and posterior circulations. Delirium can lead to inaccurate stroke scale assessments and prolong initiation of COVID-19 stroke care pathways. Future studies are needed to look into the temporal relationship between confusion and neurological manifestations.

Thromboprophylaxis for orthopedic surgery; An updated meta-analysis.

BACKGROUND: Venous thromboembolism (VTE) is a serious complication of orthopedic surgery. Low molecular weight heparin (LMWH) has been the standard of care for thromboprophylaxis in this population. However, direct oral anticoagulants (DOACs) are increasingly being used as alternatives. OBJECTIVE: To assess the efficacy and safety of DOACs versus LMWH for thromboprophylaxis in orthopedic surgery. METHODS: We searched MEDLINE, Embase, and the Cochrane Collaboration Central Register of Controlled Trials from inception until April 2020, for randomized controlled trials (RCTs) comparing DOACs with LMWH for thromboprophylaxis in orthopedic surgery. RESULTS: Twenty-five RCTs met inclusion criteria, including 40,438 patients, with a mean age of 68 years and 50% were males. Compared to LMWH, DOACs were associated with a significant reduction of major VTE; defined as the composite events of proximal deep vein thrombosis (DVT), pulmonary embolism (PE), and VTE-related mortality (RR 0.33; 95% CI: 0.20-0.53; P<0.01), and total DVT (RR: 0.59; 95% CI: 0.48-0.73; P<0.01), but not PE (RR 0.81; 95% CI: 0.49-1.34; P=0.42). There was no statistically significant difference between both groups on the incidence of major bleeding (RR 0.99; 95% CI: 0.77-1.27; P=0.92), clinically relevant non-major bleeding (RR 1.04; 95% CI: 0.92-1.17; P=0.52), all-cause mortality (RR 1.06; 95% CI: 0.64-1.76; P=0.83), VTE-related mortality (RR 0.84; 95% CI: 0.40-1.74; P=0.64) and bleeding-related mortality (RR 1.24; 95% CI: 0.30-5.18; P=0.77). CONCLUSION: For patients undergoing orthopedic surgery, thromboprophylaxis with DOACs is associated with a significant reduction of major VTE and DVT, compared to LMWH. Safety outcomes were not significantly different between both treatment groups.

Direct oral anticoagulant versus low-molecular-weight heparin for treatment of venous thromboembolism in cancer patients: An updated meta-analysis of randomized controlled trials.

BACKGROUND: Cancer associated venous thromboembolism (VTE) results in significant morbidity and mortality. Low molecular weight heparin (LMWH) has been standard of care for treatment of cancer-associated VTE, however direct oral anticoagulants (DOACs) are emerging as alternative treatment options. OBJECTIVE: To compare the benefits and harms of DOACs versus LMWH for treatment of VTE in cancer. DATA SOURCES: MEDLINE, Embase, and the Cochrane Collaboration Central Register of Controlled Trials from inception to April 2020. STUDY SELECTION: Randomized controlled trials (RCT) comparing DOACs with LMWH for treatment of VTE in cancer patients. DATA SYNTHESIS: Four good-quality RCTs, met inclusion criteria. Compared with LMWH, DOACs were associated with lower rates of VTE recurrence (RR 0.62; 95% CI: 0.44-0.87; P = 0.006), and DVT recurrence (RR 0.61; 95% CI: 0.4-0.94; P = 0.02) but not PE recurrence (RR 0.73; 95% CI: 0.51-1.04; P = 0.08), in cancer patients. However, the risk of clinically relevant non-major bleeding (CRNMB) (RR 1.58; 95% CI: 1.11-2.24; P = 0.01), and major bleeding in gastrointestinal cancer (RR 2.55; 95% CI 1.24-5.27, P = 0.01), were higher with DOACs. The risk of overall major bleeding (RR 1.33; 95% CI: 0.84-2.1; P = 0.22), all-cause mortality (RR 0.99; 95% CI: 0.84-1.17; P = 0.92), VTE-related mortality (RR: 1; 95% CI: 0.29-3.44; P = 1) and bleeding-related mortality (RR: 0.71; 95% CI: 0.17-2.91; P = 0.63), were similar in both treatment groups. CONCLUSION: Among cancer patients with VTE, treatment with DOACs is associated with a significant reduction of VTE and DVT recurrence, compared to LMWH. These benefits were offset by an increased risk of CRNMB, and major bleeding in gastrointestinal cancer.

A 29-Year-Old Male with a Fatal Case of COVID-19 Acute Respiratory Distress Syndrome (CARDS) and Ventilator-Induced Lung Injury (VILI).

BACKGROUND COVID-19 patients that develop acute respiratory distress syndrome (ARDS) "CARDS" behave differently compared to patients with classic forms of ARDS. Recently 2 CARDS phenotypes have been described, Type L and Type H. Most patients stabilize at the milder form, Type L, while an unknown subset progress to Type H, resembling full-blown ARDS. If uncorrected, phenotypic conversion can induce a rapid downward spiral towards progressive lung injury, vasoplegia, and pulmonary shrinkage, risking ventilator-induced lung injury (VILI) known as the "VILI vortex". No cases of in-hospital phenotypic conversion have been reported, while ventilation strategies in these patients differ from the lung-protective approaches seen in classic ARDS. CASE REPORT A 29-year old male was admitted with COVID-19 pneumonia complicated by severe ARDS, multi-organ failure, cytokine release syndrome, and coagulopathy during his admission. He initially resembled CARDS Type L case, although refractory hypoxemia, fevers, and a high viral burden prompted conversion to Type H within 8 days. Despite ventilation strategies, neuromuscular blockade, inhalation therapy, and vitamin C, he remained asynchronous to the ventilator with volumes and pressures beyond accepted thresholds, eventually developing a fatal tension pneumothorax. CONCLUSIONS Patients that convert to Type H can quickly enter a spiral of hypoxemia, shunting, and dead-space ventilation towards full-blown ARDS. Understanding its nuances is vital to interrupting phenotypic conversion and entry into VILI vortex. Tension pneumothorax represents a poor outcome in patients with CARDS. Further research into monitoring lung dynamics, modifying ventilation strategies, and understanding response to various modes of ventilation in CARDS are required to mitigate these adverse outcomes.

Angiotensin-Converting Enzyme (ACE) Inhibitors and Pancreatitis: A Potential Dose-dependent Relationship.

Acute pancreatitis (AP) remains one of the most common causes of emergency department visits in the USA. The literature supports an association between angiotensin-converting enzyme inhibitors (ACEi), mainly at steady-state doses, and AP[1]. We present a case of recurrent AP and pseudocyst formation following multiple ACEi dose adjustments after a steady-state period lasting for over a decade. Previous reports have rarely described ACEi-induced pancreatitis and pseudocyst development. ACEi can cause significant ductal obstruction[2] and fluid retention due to its angioedema effects. Consequently, it may trigger AP complicated by pseudocyst formation. Therefore, ACEi administration must be considered in the appropriate clinical context. LEARNING POINTS: Although rare, ACEi is an emerging cause of drug-induced pancreatitis and often goes unrecognized.Multiple dose changes within a short period of time can lead to acute drug-induced pancreatitis (DIP), in addition to classic DIP caused by steady-state doses.ACEi-induced angioedema damages the ductal architecture and also has longer-lasting effects such as pseudocyst formation.
