RESUMO
Background: Asthma is defined by the Global Initiative for Asthma (GINA) as a heterogeneous disease characterized by chronic airway inflammation. The pathogenesis of the disease is better understood with the comprehension of immunological pathways. These pathways differ by the type of recruited cells and released interleukin (IL). Thus, asthma can be classified into subtypes based on the underlying immune mechanism: eosinophilic asthma (EA) and non-eosinophilic asthma (NEA). Patients with EA tend to respond better to inhaled corticosteroid as compared to those with NEA. The distinction of EA is very important in the light of emergent type 2 inflammation targeted therapies. Methods: We performed a 1-year (2018) retrospective cohort analysis of the Nationwide Inpatient Database (NIS). We included all adult patients presenting with severe asthma. Patients were stratified into two groups: eosinophilic severe asthma and non-eosinophilic severe asthma. The primary outcomes measures were the prevalence of chronic steroid use, status asthmaticus, family history of asthma, food, drug and environmental allergies, presence of nasal polyps, allergic rhinitis, allergic dermatitis, need for mechanical ventilation, need for oxygen supplementation, gastroesophageal reflux disease, in-hospital mortality, and length of stay. We performed descriptive statistics. Continuous parametric variables were reported using a mean and standard deviation. Continuous nonparametric variables were reported using a median and interquartile range. To compare the characteristics of the two groups, we used the independent t-test for continuous parametric variables and the Mann-Whitney U test for continuous nonparametric variables. The Chi-square test was used to assess differences in categorical variables. Results: A total of 2,646 patients were included, out of which 882 belonged to the eosinophilic group and 1,764 were in the non-eosinophilic group. Comparing EA versus NEA, we have found that eosinophilic group was characterized by higher percentage of steroid use (18.3% vs. 9.5%, P < 0.001). This group also had higher rates of status asthmaticus and positive family history (P = 0.009 and 0.004, respectively). The presence of allergies, allergic rhinitis, nasal polyps, and allergic dermatitis was higher among patients with eosinophilia. The need for mechanical ventilation and supplemental oxygen was also higher among this group (P < 0.001 for both); however, there was no significant difference in mortality rate (P = 0.347) and the length of hospital stay was similar in both groups (P < 0.001). Conclusion: We showed herein that the eosinophilic subtype of asthma differs widely from the non-eosinophilic phenotype. Clinically, patients with eosinophilia might exhibit different symptomatology, more atopy, and concomitant comorbidities. However, this group might have better response to steroid therapy and might benefit from the new emergent T2 immune targeted therapy. The identification of EA is crucial for better disease control.
RESUMO
INTRODUCTION: Inflammatory bowel disease is a chronic inflammatory disorder of the gastrointestinal tract. Biologic drugs target specific molecules in the body's immune system to control inflammation. Recent studies have suggested a potential link between their use and an increased risk of nephrolithiasis. We conducted a study to further investigate this association. METHODS: The study used multiple logistic regression analysis to assess the association between the use of biologic drugs and nephrolithiasis. A p-value of <0.05 was considered statistically significant. SAS 9.4 was used for statistical analysis. RESULTS: The final sample consisted of 22,895 cases, among which 5603 (24.51%) were receiving at least one biologic drug. The biologic drugs received were as follows: Adalimumab 2437 (10.66%), Infliximab 1996 (8.73%), Vedolizumab 1397 (6.11%), Ustekinumab 1304 (5.70%); Tofacitinib, 308 (1.35%); Certolizumab, 248 (1.08%); and Golimumab, 121 (0.53%). There were 1780 (7.74%) patients with Nephrolithiasis: 438 (8.0%) patients were receiving biologic treatment. We found that the use of Vedolizumab (OR = 1.307, 95% CI 1.076-1.588, p = 0.0071) increased the odds of Nephrolithiasis by 31%. CONCLUSION: Vedolizumab use was associated with an increased risk of nephrolithiasis. The use of two or more biologic drugs also increased the risk compared to no biologic treatment.
RESUMO
The case of a 24-year-old female patient with hereditary angioedema, a normal C1 esterase inhibitor level, SLE, and pregnancy is reported.
RESUMO
Plant-based diets, consisting of legumes, are becoming increasingly a diet trend, thus a focus for food manufacturers as a source of protein. Allergy to legumes, specifically to green pea and dun pea, have been emerging. There is currently no data on pea allergy in the United States. As such, and with the progressive increase in pea/pea proteins inclusion into foods, we present in this case series children with allergic reactions to foods containing green peas or pea-protein.
RESUMO
We herein present the case of a 79-year-old female patient who presents with a single asymptomatic pulmonary nodule, melanocytic in nature, later identified as a remote secondary lesion of a primary cutaneous melanoma that was resected 22 years before presentation. Although quite atypical, the patient underwent resection of the affected pulmonary lobe; follow-up imaging did not reveal any local or distant recurrences.
RESUMO
We present herein the case of an elderly male patient, who was receiving immunotherapy for his urothelial cancer and who presented to our facility with lower extremity weakness. The patient was diagnosed with myasthenia gravis, thyroiditis, myositis and myocarditis, which were considered as immune adverse events of pembrolizumab therapy. The patient received pyridostigmine, intravenous immunoglobulin, plasmapheresis, corticosteroids, and rituximab with mild improvement of his symptoms. The patient had some neurological recovery, was discharged to a nursing facility, however he was ventilator dependent. Of importance, our case is followed by review and discussion of the literature related to immunotherapy and its side effects.
RESUMO
Duodenocaval fistula (DCF) is a rare entity which is sparsely described in the literature. Few etiologies have been listed including chemoradiation therapy. Early recognition may reduce the high mortality rate. We describe the case of a 63-year-old woman with a history of stage III ovarian cancer treated with cytoreductive surgery and adjuvant chemotherapy, including bevacizumab, who presented to the hospital because of fresh blood per rectum. One month earlier, the patient was admitted to the intensive care unit because of hemorrhagic shock secondary to a necrotic duodenal ulcer and was treated with cauterization. The patient was stable when discharged home, however, she was readmitted to the hospital because of hematemesis and hematochezia and was again in hemorrhagic shock for which the patient was urgently transfused. An abdominal computerized tomography (CT) angiography demonstrated locules of air within the intrahepatic and infrahepatic inferior vena cava (IVC), as well as evidence of communication with the duodenal lumen, and a thrombus within the IVC. The patient was evaluated by the surgical oncology and vascular teams, who deemed the patient inoperable. Our case describes ovarian malignancy, treated by radiation, leading to duodenitis, with subsequent ulcer formation. The co-administration of bevacizumab delayed gastric healing and promoted ulcer perforation favoring fistula formation.
RESUMO
BACKGROUND: Total hip arthroplasty (THA) is a common orthopaedic procedure and is expected to increase with an increasing elderly population. Many of these patients suffer from chronic diseases which might be associated with anaemia. Anaemia, by itself, increases the risk of morbidity. We aimed to delineate relationship between preoperative anaemia and postoperative composite morbidities in patients undergoing primary THA. METHODS: A cohort study analysed the data from the American College of Surgeons National Surgical Quality Improvement Program 2008-2014 database. Adult patients who underwent unilateral primary THA were included and divided into 3 groups: no anaemia, mild anaemia, and moderate-to-severe anaemia. Thirty-day mortality and morbidity were recorded as adverse events. The associations between anaemia, baseline characteristics, and adverse events were analysed after adjusting for confounders. RESULTS: Moderate-to-severe anaemia patients were at increased risk for composite morbidity (adjusted odds ratio, 1.43 [1.17-1.74]) when compared to non-anaemics. The stratification revealed a significant effect of younger age, male gender, white race, obesity, general anaesthesia, and mean operative time >120 minutes in patients with moderate-to-severe anaemia. These patients were also at a higher risk of developing several specific morbidities. CONCLUSION: Moderate-to-severe anaemia increases the risk for composite morbidities, but not mortality in patients undergoing primary THA. Further studies are needed to assess whether preoperative management of moderate-to-severe anaemia would improve outcomes in patients undergoing THA.

Full extent of gender differences on postoperative outcomes has never been studied on large scale, specifically postoperative complications. This study aims to assess the effect of gender on 30-day morbidity and mortality after major surgery. A retrospective cohort study was carried out using data of patients undergoing major surgeries from the American College of Surgeons' National Surgical Quality Improvement Program database between 2008 and 2011. Demographics, pre- and perioperative risk factors, as well as 30-day morbidities, both overall and specific, were reviewed. The 30-day mortality data were also assessed. Multivariate logistic regression analyses, basic (Adj1) and extended (Adj2), were used to assess the association between gender and outcomes. Out of 1,409,131 patients, 57.2 per cent were females. Females had lower prevalence of most system-specific risk variables. Overall morbidities were also lower in females versus males, even after adjustment for variables [total overall morbidity: ORadj2 = 0.9 (0.89-0.92), P < 0.0001] except in some cases such as after cardiac surgeries [ORadj2 = 1.29 (1.14-1.44), P < 0.0001] and vascular surgeries [ORadj2 = 1.14 (1.10-1.18), P < 0.0001], where overall morbidities of females were higher. Specific morbidities were also lower in females than in males in all types of complications except central nervous system-related postoperative complications [ORadj2 = 1.15 (1.08-1.22), P < 0.0001] and return to the operating room [ORadj2 = 1.06 (1.04-1.08), P < 0.0001]. The 30-day mortality rate for females was lower than males [ORadj2 = 0.99 (0.96-1.03), P = 0.94]. Female gender was associated with less perioperative morbidity and mortality versus males, but they did worse after cardiovascular procedures and had more central nervous system-related complications. These outcomes should be taken into consideration by surgeons and should be evaluated further in future studies.

Ankle fractures requiring open reduction and internal fixation vary in severity from unimalleolar fractures to bimalleolar/trimalleolar (BT) fractures to pilon fractures. Consequently, the postoperative outcomes with these surgeries can vary. Most previous studies of these injuries had small sample sizes, studied a single risk factor or adverse event, or did not compare different injuries by severity. The purpose of the present study was to describe and compare the patient characteristics and postoperative outcomes of 2 high-energy ankle fractures: BT and pilon fractures. The relevant patients were identified from the American College of Surgeons National Surgical Quality Improvement Program database using the Current Procedural Terminology codes for BT and pilon fractures. Patient demographics, characteristics, comorbidities, and 30-day mortality and adverse events were recorded and compared between the 2 types of ankle fractures. More than 45% of patients with these fracture types were aged 40 to 65 years. Pilon fractures occurred more frequently in younger patients, were more likely to occur in men, required a longer hospital stay and operative time, were less likely to occur in patients with a body mass index of >30 kg/m2, and conferred a greater risk of wound complications (odds ratio 1.76; p = .048) compared with BT fractures. The findings from the present study help us understand the differences in patient characteristics and potential early adverse events after open reduction and internal fixation of BT fractures versus pilon fractures.
