RESUMO

Cobalamin-deficient thrombotic microangiopathy or vitamin B12 deficiency presenting as pseudo-thrombotic microangiopathy is a rare disorder that can be misdiagnosed as thrombotic thrombocytopenic purpura. Patients with this condition are at risk of receiving unnecessary plasmapheresis with a potential delay in appropriate therapy with vitamin B12 supplementation. There are no established diagnostic criteria for this condition in clinical practice. We performed a systematic review of case reports published between January 2018 and January 2023 to analyze the clinical characteristics, risk factors, and patterns of laboratory markers to improve the diagnostic criteria for this condition.

RESUMO

Colon cancer remains a leading cause of cancer-related deaths, and there has been a rise in the incidence of early-onset colon cancer or colon cancer diagnosed before the age of 50 years old. Early-onset colon cancer has several differences in clinical presentation, as well as histopathology, genetic alteration, and molecular profiling. Early-onset colon cancer can be differentiated into familial type that includes hereditary familial syndrome and sporadic type. Demographic variance also exists in both developing and developed countries. Due to the rising incidence of colon cancer diagnosed in younger age, it is imperative to examine the available evidence regarding the mortality rate of early-onset colon cancer. Colon cancer is affected by numerous modifiable and non-modifiable risk factors. Increasing obesity and lifestyle disorders in the younger population, such as smoking, may influence this increasing trend. There are existing guidelines for colon cancer screening in both average-risk and high-risk individuals. This narrative review aims to highlight the pathogenesis of early-onset CRC; its clinical presentation, treatment, prognosis; and how it differs from late-onset CRC.

RESUMO

Radiation oncology (RO) plays a crucial role in cancer care; cancer patients often undergo their initial diagnostic study by general physicians. However, studies have shown that most physicians are uncomfortable referring cancer patients to radiation therapy (RT). To assess the knowledge of RO among non-oncology physicians, we sent invitations to complete an online survey that required the responders to self-rate their understanding of RT and objective assessment. The survey was targeted at hospitalists and primary care physicians. Forty physicians responded to the survey, and 89.7% practiced primarily as hospitalists, with 67% being Internal Medicine graduates. Fifty percent of physicians have referred patients to RO before, although more than 90% have not done additional CME (continuing medical education) in Oncology. More than 50% of recent graduates (one to five years post-residency) self-rated themselves as "not knowledgeable" when it comes referral process to RO as well as general knowledge regarding RT. Factors, such as "type of cancer," "patients' wishes," and "life expectancy," are most cited as factors influencing the decision for a referral.

RESUMO

Retroperitoneal paraganglioma remains an extremely rare type of tumor that arises from either sympathetic or parasympathetic neural crest cells. It could be functional or non-functional. Non-functional paraganglioma may present as a diagnostic challenge since patients are usually asymptomatic and tend to present to the hospital with complications from the invasion of the tumor. Malignancy is usually determined by the degree of metastasis. The gold standard of diagnosis is biopsy and obtaining a sample for histological examination. This author presents a case of asymptomatic, non-functional retroperitoneal paraganglioma with distant metastasis.

RESUMO

Since the IARC (International Agency for Research on Cancer) announcement in 2007 indicating the possibility of night-shift work carrying carcinogenesis risk, multiple studies on a global level have been conducted to investigate the correlation between night-shift work and cancer development. Circadian rhythm disruption and decreased melatonin production have been postulated as potential contributing factors. There is also growing evidence that night-shift workers tend to adopt unhealthier lifestyles which contribute to poorer health and increase the risk of developing diseases such as cancer. No experimental study has been specifically dedicated to testing specific methods that could decrease cancer risk in night-shift workers. While there are a few studies that investigate melatonin's concurrent use with chemotherapy in cancer patients, there is yet to be seen for studies that investigate melatonin specifically as a cancer prevention method. This narrative review aims to examine current evidence of healthcare night-shift work's risk in cancer incidence, potential pathogenesis, and its significance in clinical practice.

RESUMO

Liver cirrhosis remains a major public health issue. Liver fibrosis leading to cirrhosis is the terminal stage of various chronic liver diseases. Inflammatory cytokines are involved in the pathogenesis. Patients with cirrhosis often have hematological abnormalities, such as anemia and thrombocytopenia, which have multifactorial etiologies. Anemia in cirrhosis could be related to bleeding leading to iron deficiency anemia or other nutritional anemia such as vitamin B12 and folate deficiency. The pathophysiology of thrombocytopenia in liver cirrhosis has been postulated to range from splenic sequestration to bone marrow suppression from toxic agents, such as alcohol. It often complicates management due to the risk of bleeding with severely low platelets. This review aimed to highlight pathogenesis of liver cirrhosis, hematological abnormalities in liver cirrhosis, and their clinical significance.

RESUMO

Coronavirus disease 2019 (COVID-19) is a febrile respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It may develop into respiratory failure or pneumonia. Antimicrobials have facilitated medical progress for decades. However, antimicrobial resistance (AMR) limits our ability to treat diseases and undermines efforts to attain health-related sustainable development and universal health coverage objectives. Antimicrobial resistance is a major concern that must be addressed immediately. The principles of appropriate prescription, optimal use of antimicrobials, quality diagnosis and treatment, and infection reduction and prevention have led to antimicrobial stewardship initiatives. During the current COVID-19 epidemic, there are possible hazards to antimicrobial stewardship measures and drug resistance. Many people with mild illnesses but without pneumonia or moderate infections with pneumonia are administered antibiotics. Antimicrobial therapy has no documented benefit in COVID-19 patients without microbial co-infection. COVID-19 patients may have an increased risk of developing concomitant microbial infections, which would necessitate antibiotic treatment. This review evaluated the role of empiric antibiotics in COVID-19 patients.

RESUMO

Coronavirus disease 2019 (COVID-19) is known to have neurological manifestations and one of them is acute transverse myelitis (ATM). Despite being exceedingly rare (1.34-4.6 cases per million/year), COVID-19-associated ATM cases have continuously been reported and have significant health impact to patients. This case report presents a previously healthy, unvaccinated male who developed COVID-19-associated ATM.

RESUMO

BACKGROUND: Hemolytic uremic syndrome (HUS) is a rare but challenging disease with varying degrees of mortality and prognosis. We aim to evaluate the trends and outcomes of hospitalizations due to HUS by utilizing a large population-based dataset. METHODS: We derived a study cohort from the Nationwide Inpatient Sample (NIS) for the years 2007-2018. Our primary outcomes were in-hospital mortality, discharge disposition, and predictors of poor outcomes. We then utilized the Cochran Armitage trend test and multivariable survey logistic regression models to analyze the trends, outcomes, and predictors. RESULTS: A total of 8043 hospitalizations ranging from age zero to above 65 years of age occurred due to HUS from 2007-2018. The number of hospitalizations with HUS increased steadily from 528 in 2007 to 800 in 2013, but afterwards, we noticed a steady decline to 620 in 2018. Additionally, trends of in-hospital mortality slowly increased over the study period but we noticed a decline in the rate of discharge to skilled nursing facilities (SNFs). Furthermore, in multivariable regression analysis, predictors of increased mortality in hospitalized HUS patients were advanced age (95%CI: 1.221-1.686; p-value <0.0001) and requirement for dialysis (95%CI: 1.141-4.167; p-value: <0.0001). Advanced age >65 years (OR: 2.599, 95%CI: 1.406-4.803; p-value: 0.0023), as well as comorbidities such as diabetes mellitus and pulmonary circulatory diseases, which are under vascular events (OR: 1.467, 95%CI:1.075-2.000; p-value: 0.0156), were shown to have a higher rate of discharge to SNFs. Moreover, patients needing intravenous immunoglobulin (IVIG) and plasmapheresis had high odds of discharge to SNFs ((OR: 1.99, 95%CI: 1.307-3.03; p-value: 0.0013) and (OR: 5.509, 95%CI: 2.807- 10.809; p-value <0.0001), respectively), as well as smaller hospital bed size and hospital type (OR: 1.849, 95%CI: 1.142-2.993; p-value: 0.012). CONCLUSION: In this national representative study, we observed a total decrease in hospitalizations as well as discharge to SNFs; however we saw an increase in inpatient mortality. We also identified multiple predictors significantly associated with increased mortality, some of which are potentially modifiable and can be points of interest for future studies.

RESUMO

Among the candida species, Candida auris (C. auris) is multidrug-resistant and is associated with invasive hospital-acquired infection and high mortality. We are going to present a case report about C. auris in an immunocompetent patient. The patient was admitted due to traumatic sub dural hemorrhage and during the hospital course he developed fever. Blood cultures grew C. auris. Our aim is to raise awareness regarding C. auris for early detection and prevention of hospital-acquired transmission of the infection.
