Carbapenem-resistant bacilli in a hospital in southern Brazil: prevalence and therapeutic implications.

Background: Gram-negative bacilli (GNB), notably Acinetobacter spp., Pseudomonas spp., and Klebsiella spp.

Multivariate quasi-beta regression models for continuous bounded data.

We propose a multivariate regression model to deal with multiple continuous bounded data. The proposed model is based on second-moment assumptions, only. We adopted the quasi-score and Pearson estimating functions for estimation of the regression and dispersion parameters, respectively.

Facial Nerve Palsy Complicated by Masked Tuberculous Mastoiditis in a Recently Transplanted Patient.

Mastoiditis is a complication of the medium otitis characterized by suppuration and destruction of the mastoid cells and the pyramid petrosa; its tuberculous etiology has decreased in the last 40 years. Paralysis resulting from mastoiditis is more common in children. The incidence of mastoiditis has risen, although there are no reports in the literature associated with renal transplants.

Outcomes after Haploidentical Stem Cell Transplantation with Post-Transplantation Cyclophosphamide in Patients with Primary Immunodeficiency Diseases.

Allogeneic hematopoietic stem cell transplantation (HCT) can cure primary immunodeficiency diseases (PID). When a HLA-matched donor is not available, a haploidentical family donor may be considered. The use of T cell-replete haploidentical HCT with post-transplantation cyclophosphamide (haplo-PTCy) in children with PID has been reported in few case series.

Trabecular bone score (TBS) and bone mineral density in patients with long-term therapy with warfarin.

Unlabelled: In this study, we compared patients using the anticoagulant warfarin for more than a year with a control group with similar characteristics but without using the drug. We demonstrated worse BMD and bone quality by trabecular bone score (TBS) in patients using warfarin for more than 1 year.

Purpose: Evaluate the bone mineral density (BMD) and the trabecular bone score (TBS) of patients taking warfarin for more than 1 year compared with a control group.

Target-based approach for osteoarthritis treatment.

There is still no definitive treatment for knee osteoarthritis (OA). We are certainly far from a consensus on the best form of treatment or on an effective treatment recommendation. There are reasons for the current equivocal treatment recommendations in the face of this very serious health problem.

Metabolic syndrome and its components in adult hypopituitary patients.

Purpose: To evaluate the prevalence of metabolic syndrome (MetS) and its components in adult hypopituitary patients.

Patients And Methods: Retrospective, cross-sectional analysis of a cohort of hypopituitary adult patients followed in a single reference center for pituitary diseases. MetS was defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria.

Toxicity Profile of PEG-Asparaginase in Adult Patients With Acute Lymphoblastic Leukemia in Brazil: A Multicenter Cross-Sectional Study.

Background: Currently, pediatric-inspired regimens are commonly applied to adults with acute lymphoblastic leukemia (ALL) after the recent recognition that these protocols improve survival. While asparaginase in whatever available formulation is a key component of modern treatment of ALL, many adult oncologists and hematologists struggle to deal with its particular toxicities in clinical practice. We reviewed toxicity outcomes of pegylated asparaginase (PEG-ASP) in adults with ALL treated in 3 reference centers in Brazil.

Primary hyperparathyroidism.

Primary hyperparathyroidism (PHPT) is a condition that affects calcium metabolism due to parathyroid hormone (PTH) hypersecretion leading to hypercalcemia. Manifestations have changed over time, from a symptomatic disease with bone pain, fractures, nephrolithiasis, and muscle weakness, to a condition that is mainly asymptomatic (80-90%). Typical symptoms and signs occur in the bones and kidneys and atypical manifestations are cardiovascular, neuropsychiatric and cognitive, neuromuscular, rheumatological, and gastrointestinal.

Wake-Up Headache Is Associated With Sleep Bruxism.

Objective: To investigate the relationship between the frequency of sleep bruxism and report of morning headaches, and associations with depression and/or anxiety.

Background: The association between sleep bruxism and headaches in the morning, and between these factors and affective disorders, has been examined in several investigations. Although headache is cited by the International Classification of Sleep Disorders as a symptom associated with sleep bruxism, only a small number of studies have investigated the association between the frequencies of headaches in the morning and bruxism.

Surgical margins required for basal cell carcinomas treated with Mohs micrographic surgery according to tumor features.

Background: Basal cell carcinomas (BCCs) with high-risk features are preferably treated by Mohs micrographic surgery. Studies have shown clinicopathologic characteristics that may predict more stages required for clearance. However, few studies have correlated such factors with the number of millimeters removed per stage.

Esophageal manometry in systemic sclerosis: findings and association with clinical manifestations.

Introduction: Systemic sclerosis (SSC) is an autoimmune disorder that affects several organs of unknown etiology, characterized by vascular damage and fibrosis of the skin and organs. Among the organs involved are the esophagus and the lung.

Objectives: To relate the profile of changes in esophageal electromanometry (EM), the profile of skin involvement, interstitial pneumopathy (ILD), and esophageal symptoms in SSC patients.

Fertility issues in aggressive pituitary tumors.

The management of aggressive pituitary adenomas represents a special clinical challenge, and usually involves a combination of surgery, radiotherapy and pharmacological agents to control tumor growth and hormone abnormalities. Fertility is commonly affected in these patients due to compressive effects of the tumor, pituitary hormone dysfunction or as a result of the multiple therapies. The initial approach to restore fertility involves the reduction of tumor volume by the use of dopamine agonists in prolactinomas and by surgery in other pituitary adenomas.

Outcomes of HIV-associated Burkitt Lymphoma in Brazil: High treatment toxicity and refractoriness rates - A multicenter cohort study.

Background: Although the increased use of combined antiretroviral therapy (cART) has decreased the incidence of lymphomas HIV-associated, Burkitt lymphoma (BL) incidence remains stable. Reported outcomes on HIV-associated BL from developed countries seem to corroborate that the regimens do not need to be tailored to the HIV-positive population.

Materials And Methods: This is a retrospective multicenter cohort study from Brazil, including HIV-positive patients aged 15 years and above diagnosed with BL.

Enzyme Replacement Therapy Decreases Left Ventricular Mass Index in Patients with Hunter Syndrome?

Although enzyme replacement therapy (ERT) has shown benefit in improving cardiac systolic function in a murine model of cardiomyopathy associated with Hunter syndrome, few studies have analyzed its effect in humans. We evaluated the effect of ERT on patients with Hunter syndrome-related cardiomyopathy. We performed a retrospective analysis of serial transthoracic echocardiograms performed before and over the first 5 years after treatment initiation, in 14 patients with Hunter syndrome.

Penetrance of the R337H Mutation and Pediatric Adrenocortical Carcinoma Incidence Associated with Environmental Influences in a 12-Year Observational Cohort in Southern Brazil.

The R337H mutation is associated with increased incidence of pediatric adrenocortical tumor (ACT). The different environmental conditions where R337H carriers live have not been systematically analyzed. Here, the R337H frequencies, ACT incidences, and R337H penetrance for ACT were calculated using the 2006 cohort with 4165 R337H carriers living in Paraná state (PR) subregions.

Microvascular invasion in hepatocellular carcinoma: is it predictable with quantitative computed tomography parameters?

Objective: To investigate whether quantitative computed tomography (CT) measurements can predict microvascular invasion (MVI) in hepatocellular carcinoma (HCC).

Materials And Methods: This was a retrospective analysis of 200 cases of surgically proven HCCs in 125 consecutive patients evaluated between March 2010 and November 2017. We quantitatively measured regions of interest in lesions and adjacent areas of the liver on unenhanced CT scans, as well as in the arterial, portal venous, and equilibrium phases on contrast-enhanced CT scans.
