RESUMEN
Naloxone, an opioid receptor antagonist, effectively reverses opioid overdose and opioid-induced respiratory depression. A few side effects were reported after naloxone administration, including arrhythmia and pulmonary edema. Although rare, naloxone-induced pulmonary edema can be a severe and sometimes life-threatening complication requiring mechanical ventilation. This condition is predominantly linked to an upsurge in catecholamines after opioid reversal as part of acute withdrawal syndrome, especially seen in patients who chronically use opioids. In this report, we present a case of a 66-year-old patient who developed pulmonary edema following the administration of multiple doses of intravenous and intranasal naloxone for opioid overdose. This case highlights the potential adverse effects associated with naloxone use and discusses how to employ this life-saving medication with minimal side effects.
RESUMEN
Bilateral hyperglycemic nonketotic chorea is a rare complication of hyperglycemia. In most cases, the literature illustrates patients presenting with unilateral chorea with image findings significant for hyperintense lesions in the basal ganglia on magnetic resonance imaging (MRI) or hyperdensities on computerized tomography (CT). Here, we present a case of an 83-year-old patient who was admitted to the hospital due to acute onset of orofacial and bilateral upper extremity chorea. She had no previous history of infection, genetic mutation, neoplasms, neurodegeneration, stroke, metabolic disease, drug exposure, or autoimmune disease. Surprisingly, her MRI showed only chronic microvascular changes in periventricular white matter without basal ganglia abnormalities. However, she was noted to have marked worsening of her glycemic control over the preceding 12 months based on worsening glycated hemoglobin (HbA1c) levels and elevated serum glucose on presentation. A literature review indicates that chorea caused by hyperglycemia is at times reversible with glycemic control, but as demonstrated in our patient, this is not always necessarily the case. A similar course has only been elaborated in a few other cases in the literature. We will also review the pathogenesis, the usual disease clinical course and standard treatment from the literature.
RESUMEN
BACKGROUND: This study aimed to evaluate the impact of Insulin Degludec Aspart on daily insulin dose in comparison with premixed insulin aspart. METHODS: It was a Quasi-Experimental study conducted in the Department of Pharmacology, Army Medical College, National University of Medical Sciences, Rawalpindi and the Department of Medicine, Pak Emirates Military Hospital, Rawalpindi. One hundred and twenty participants with documented type 2 diabetes, taking premixed insulin aspart therapy were enrolled in the study. Sixty participants were substituted with insulin degludec aspart from premixed insulin aspart. Daily units of insulin were recorded for 12 weeks and compared for both groups. SPSS version 26 was used for analysing the study results. RESULTS: Participants of the insulin degludec aspart group showed a significant reduction in the daily insulin dose compared to the premixed insulin aspart group. Fifty-two units per day were administered in the participants of the premixed insulin aspart patients while insulin degludec aspart participants received 40 units of median daily insulin dose (p-value<0.001). CONCLUSIONS: Insulin degludec aspart proved superior to premixed insulin aspart in a reduction in the daily dose of insulin with insulin degludec aspart.

BACKGROUND: Data about long-term prognosis after hospitalisation of elderly multimorbid patients remains scarce. OBJECTIVES: Evaluate medium and long-term prognosis in hospitalised patients older than 75 years of age with multimorbidity. Explore the impact of gender, age, frailty, physical dependence, and chronic diseases on mortality over a seven-year period. METHODS: We included prospectively all patients hospitalised for medical reasons over 75 years of age with two or more chronic illnesses in a specialised ward. Data on chronic diseases were collected using the Charlson comorbidity index and a questionnaire for disorders not included in this index. Demographic characteristics, Clinical Frailty Scale, Barthel index, and complications during hospitalisation were collected. RESULTS: 514 patients (46% males) with a mean age of 85 (± 5) years were included. The median follow-up was 755 days (interquartile range 25-75%: 76-1,342). Mortality ranged from 44% to 68%, 82% and 91% at one, three, five, and seven years. At inclusion, men were slightly younger and with lower levels of physical impairment. Nevertheless, in the multivariate analysis, men had higher mortality (p<0.001; H.R.:1.43; 95% C.I.95%:1.16-1.75). Age, Clinical Frailty Scale, Barthel, and Charlson indexes were significant predictors in the univariate and multivariate analysis (all p<0.001). Dementia and neoplastic diseases were statistically significant in the unadjusted but not the adjusted model. In a cluster analysis, three patterns of patients were identified, with increasing significant mortality differences between them (p<0.001; H.R.:1.67; 95% CI: 1.49-1.88). CONCLUSIONS: In our cohort, individual diseases had a limited predictive prognostic capacity, while the combination of chronic illness, frailty, and physical dependence were independent predictors of survival.

OBJECTIVE: Compression of the left renal vein by the superior mesenteric artery, known as nutcracker phenomenon (NCP), can cause retrograde flow and congestion in communicating venous systems. It has recently been speculated that NCP can result in retrograde flow and congestion of the lumbar veins and epidural venous plexus (EVP), thereby affecting the central nervous system. This study describes the novel use of time-resolved magnetic resonance angiography (trMRA) to evaluate for retrograde left second lumbar vein (L2LV) flow and early EVP enhancement in patients with chronic daily headache (CDH) with and without NCP. METHODS: A retrospective analysis was performed of 31 patients with CDH (27 females and 4 males; median age, 38 years [range, 18-63 years]) who underwent trMRA centered over the L2LV to evaluate the direction of blood flow and presence of early EVP enhancement from May 2020 to March 2022. Descriptive statistics were performed, and anatomic associations were analyzed in patients with and without retrograde L2LV flow and early EVP enhancement. The accuracy of magnetic resonance imaging findings in detecting these flow patterns was also assessed. RESULTS: Patients with NCP who demonstrated narrowing of the left renal vein, a positive beak sign ( P = 0.052), decreased aortomesenteric distance ( P = 0.038), and decreased SMA angle demonstrated increased rates of retrograde L2LV flow and early EVP enhancement. A positive beak sign was 83% specific, and an aortomesenteric distance of ≤6.5 mm was 61% sensitive and 83% specific for identifying retrograde L2LV flow with early regional EVP enhancement in patients with CDH. CONCLUSIONS: Retrograde L2LV flow with early EVP enhancement in CDH patients can be effectively evaluated using trMRA and was seen with greater propensity in those patients with NCP.

Background: Several mechanisms have been proposed to explain why chronic obstructive pulmonary disease (COPD) impairs the prognosis of coronary events. We aimed to explore COPD variables related to a worse prognosis in patients undergoing percutaneous coronary intervention (PCI). Methods: Patients with an acute coronary event treated by PCI were prospectively included. One month after discharge, clinical characteristics, comorbidities measured with the Charlson index, and prognostic coronary scales (logistic EuroSCORE; GRACE 2.0) were collected. Post-bronchodilator spirometry, arterial stiffness, and serum inflammatory and myocardial biomarkers were measured. Lung plasmatic biomarkers (Surfactant protein D, desmosine, and Clara cell secretory protein-16) were determined with ELISA. COPD was defined by the fixed ratio (FEV1/FVC <70%). Spirometric values were also analyzed as continuous variables using adjusted and non-adjusted ANCOVA analysis. Finally, we evaluated the presence of a respiratory pattern defined by non-stratified spirometric values and pulmonary biomarkers. Results: A total of 164 patients with a mean age of 65 (±10) years (79% males) were included. COPD was diagnosed in 56 (34%) patients (68% previously undiagnosed). COPD patients had a longer smoking history, higher scores on the EuroSCORE (p < 0.0001) and GRACE 2.0 (p < 0.001) scales, and more comorbidities (p = 0.006). Arterial stiffness determined by pulse wave velocity was increased in COPD patients (7.35 m/s vs 6.60 m/s; p = 0.006). Serum values of high sensitive T troponin (p = 0.007) and surfactant protein D (p = 0.003) were also higher in COPD patients. FEV1% remained significantly associated with arterial stiffness and surfactant protein D in the adjusted ANCOVA analysis. In the cluster exploration, 53% of the patients had a respiratory pattern. Conclusion: COPD affects one-third of patients with an acute coronary event and frequently remains undiagnosed. Several mechanisms, including arterial stiffness and SPD, were increased in COPD patients. Their relationship with the prognosis should be confirmed with longitudinal follow-up of the cohort.

Rationale: Current guidelines for non-small cell lung cancer (NSCLC) mediastinal staging recommend starting invasive staging with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). However, the indication to confirm a negative result of EBUS-TBNA by means of video-assisted mediastinoscopy (VAM) before resection differs in every guideline. Objectives: Our aim was to evaluate the current evidence regarding the added value of confirmatory VAM after a negative EBUS-TBNA result for mediastinal staging in patients with NSCLC. Methods: Systematic searches of studies on EBUS-TBNA for NSCLC mediastinal staging with or without confirmatory VAM but with surgical confirmation of negative results were conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement in PubMed, SCOPUS, the Cochrane Library, and guidelines from 2005 through November 2021. In the meta-analysis, the sensitivity of confirmatory VAM after a negative EBUS-TBNA result, as well as the sensitivity and negative predictive value of the combination EBUS-TBNA plus confirmatory VAM, alongside the number of confirmatory VAMs required to detect additional N2/3 disease (number needed to treat [NNT]), in patients with a previous negative EBUS-TBNA result were estimated. Results: A total of 5,412 articles were found, of which 29 studies were included. Random effects meta-analysis showed a sensitivity of 66.9% (95% confidence interval [CI], 55.8-77.1%) for confirmatory VAM, and 96.7% (95% CI, 95.1-98%) for the combination EBUS-TBNA plus confirmatory VAM. Negative predictive value in studies with confirmatory VAM increased of 79.2% (95% CI, 71.4-86.1%) for EBUS-TBNA alone to 91.8% (95% CI, 87.1-95.5%) for EBUS-TBNA plus confirmatory VAM. The NNT of confirmatory VAM in patients with a previous negative EBUS-TBNA result was 23.8 (95% CI, 19.3-31.2). Conclusions: Confirmatory VAM after negative EBUS-TBNA reduces the rate of unforeseen N2/3 disease, but with a high NNT, and it should be recommended only for certain cases yet to be defined.

Intravenous leiomyomatosis is a histologically benign smooth muscle tumor that arises either by direct extension of a uterine leiomyoma into the adjacent veins or by vascular intimal smooth muscle proliferation. Herein, we report the case of a 60-year-old female who was noted to have suspected cardiac mass on elective echocardiography done electively for abnormal electrocardiographic findings. Computed tomography and cardiac magnetic resonance indicated the presence of an intravenous leiomyoma originating from the uterus and extending to the inferior vena cava and right atrium. The patient was managed with a single-stage surgery involving cardiopulmonary bypass and excision of the right atrial mass, excision of the inferior vena cava tumor thrombus, and total abdominal hysterectomy and bilateral salpingo-oophorectomy.
RESUMEN
Abdominal surgery in patients with cirrhosis and portal hypertension remains a challenge due to higher risk of morbidity and mortality. Preoperative elective transjugular intrahepatic portosystemic shunt (TIPS) is increasingly being used in these patient population. Herein, we report a case of 65-year-old male with biopsy-proven ascending colon cancer and cirrhosis. As a sequalae of portal hypertension, patient also had large caput medusae which posed significant challenge to the surgical approach for resection of the colon cancer. The patient was managed initially with placement of TIPS to decompress the portal pressures and caput medusae and allow safe surgical field for curative resection of the colon cancer. Following this, the patient underwent uneventful laparoscopic right hemicolectomy.
