title: Fibrous dysplasia: rare manifestation in the temporal bone

description: Abstract Introduction: Fibrous dysplasia is a benign disorder, in which normal bone is replaced by fibrosis and immature bone trabeculae, showing a similar distribution between the genders, and being more prevalent in the earlier decades of life. Fibrous dysplasia of the temporal bone is a rare condition, and there is no consensus as to whether it is more common in monostotic or polyostotic forms. External auditory meatus stenosis and conductive dysacusis are the most common manifestations, with cholesteatoma being a common complication, whereas the involvement of the otic capsule is an unusual one. Surgical treatment is indicated to control pain or dysacusis, otorrhea, cholesteatoma, and deformity. Objectives: To describe the clinical experience of a tertiary referral hospital with cases of fibrous dysplasia of the temporal bone. Methods: Sampling of patients diagnosed with fibrous dysplasia of the temporal bone, confirmed by tomography, treated at the pediatric otology and otorhinolaryngology outpatient clinics, between 2015 and 2018. The assessed variables were age, gender, laterality, external auditory meatus stenosis, deformity, hearing loss, presence of secondary cholesteatoma of the external auditory meatus, lesion extension and management. Results: Five patients were included, four females and one male, with age ranging from 13 to 34 years. Three had the polyostotic form and two the monostotic form of fibrous dysplasia of the temporal bone. Four patients had local deformity and external auditory meatus stenosis, two of which progressed to cholesteatoma. All patients showed some degree of hearing impairment. All had preserved otic capsule at the tomography. Two patients are currently undergoing clinical observation; two were submitted to tympanomastoidectomy due to secondary cholesteatoma; one was submitted to lesion resection, aiming to control the dysacusis progression. Conclusion: Five cases of fibrous dysplasia of the temporal bone were described, a rare disorder of which the otologist should be aware.

title: Analysis of the federal funding of the Unified Health System to fight the COVID-19

description: ABSTRACT The purpose of this article is to analyze the federal funding of the Unified Health System (SUS) to fight the COVID-19 pandemic in 2020 and during the first four months of 2021 – periods characterized as the first and second waves. Documentary research was carried out, with data available on official websites. The pandemic took hold in Brazil in February 2020, in the context of the chronic underfunding of SUS, which deepened with the strangulation of appropriations verified from the Constitutional Amendment 95/2016, which defined the ceiling on primary expenditure and the freezing of the federal floor of SUS until 2036, at the same value as the 2017 floor. This constitutional measure made it possible to deepen the fiscal austerity policy by reducing primary expenditure and public debt in relation to the Gross Domestic Product. These goals also conditioned federal funding to combat the COVID-19 pandemic in 2020 and 2021, whose budget and financial execution can be characterized as reactive and delayed. This form of execution compromised meeting the health needs of the population, in addition to harming the management of SUS in subnational government spheres.

title: A POPULATION STUDY ON GENDER AND ETHNICITY DIFFERENCES IN GALLBLADDER DISEASE IN BRAZIL

description: ABSTRACT - BACKGROUND: Gallbladder diseases (GBD) are one of the most common medical conditions requiring surgical intervention, both electively and urgently. It is widely accepted that sex and ethnic characteristics mighty influence both prevalence and outcomes. AIM: This study aimed to evaluate the differences on distributions of gender and ethnicity related to the epidemiology of GBD in the Brazilian public health system. METHODS: DATASUS was used to retrieve patients’ data recorded under the International Code of Diseases (ICD-10) - code K80 from January 2008 to December 2019. The number of admissions, modality of care, number of deaths, and in-hospital mortality rate were analyzed by gender and ethnic groups. RESULTS: Between 2008 and 2019, a total of 2,899,712 patients with cholelithiasis/cholecystitis (K80) were admitted to the hospitals of the Brazilian Unified Health System, of whom only 22.7% were males. Yet, the in-hospital mortality rate was significantly higher in males (15.9 per 1,000 male patients) than females (6.3 per 1,000 female patients) (p&lt;0.05). Moreover, men presented a significantly higher risk of death (RR=2.5; p&lt;0.05) and longer hospital stay (4.4 days vs. 3.3 days; p&lt;0.05) than females. Compared to females, men presented a higher risk of death across all self-declared ethnic groups: whites (RR=2.4; p&lt;0.05), blacks (RR=2.7; p&lt;0.05), browns (RR=2.6; p&lt;0.05), and Brazilian Indians (RR=2.13; p&lt;0.05). CONCLUSION: In the years 2008-2019, women presented the highest prevalence of hospital admissions for GBD in Brazil, and men were associated with worse outcomes, including all ethnic groups.

title: INFLAMMATORY BOWEL DISEASES: CHARACTERISTICS, EVOLUTION, AND QUALITY OF LIFE

description: ABSTRACT - BACKGROUND: Inflammatory bowel diseases present progressive and potentially debilitating characteristics with an impact on health-related quality of life (QoL) throughout the course of the disease, and this parameter may even be used as a method of evaluating response to treatment. AIM: The aim of this study was to analyze epidemiological data, medications in use, previous surgeries, and hospitalizations in patients with inflammatory bowel diseases, and to determine the impairment in QoL of these patients. METHODS: This is a prospective, cross-sectional, observational study in patients with inflammatory bowel disease followed up in a tertiary hospital in São Paulo-SP, Brazil. General and disease-related, evolution, and quality-of-life data were analyzed using a validated quality-of-life questionnaire, namely, Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS: Fifty-six individuals were evaluated, with an equal number of patients with Crohn’s disease and ulcerative colitis. A higher prevalence of previous surgeries (p=0.001) and hospitalizations (p=0.003) for clinical-surgical complications was observed in patients with Crohn’s disease. In addition, the impairment of QoL also occurred more significantly in these patients (p=0.022), and there was a greater impact on females in both forms of inflammatory bowel disease (p=0.005). CONCLUSIONS: Patients with Crohn’s disease are more commonly submitted to surgeries and hospitalizations. Patients affected by both forms of inflammatory bowel disease present impairments in QoL, which are mainly related to intestinal symptoms, and females are more affected than men.

title: Prognostic factors in metastatic nasopharyngeal carcinoma

description: Abstract Introduction: Nasopharyngeal carcinoma has the highest metastatic potential of all head and neck cancers. The survival time of patients with nasopharyngeal carcinoma has improved significantly in the last decades due to the use of combination of chemotherapy and radiotherapy, as well as advances in radiotherapy techniques. However, appropriately 30% of patients with nasopharyngeal carcinoma suffer a poor prognosis, mainly due to distant metastasis. Objective: The study aimed to identify the survival and prognostic factors in metastatic nasopharyngeal carcinoma. Methods: A retrospective analysis was conducted in patients treated for synchronous metastatic nasopharyngeal carcinoma or metachronous metastatic nasopharyngeal carcinoma for 14years (2003–2016). Overall survival was analyzed using the Kaplan-Meier method and compared using the log-rank test for the whole population and both groups of patients. Multivariate analysis was performed using the Cox model; p-values &lt; 0.05 were considered to indicate statistical significance. Results: One hundred and twelve patients with metastatic nasopharyngeal carcinoma were included (51 patients with metastatic nasopharyngeal carcinoma, and 61 patients with metachronous metastatic nasopharyngeal carcinoma). In the whole population, the median overall survival was 10 months (1–156 months). In the multivariate analysis, female gender, poor performance status (WHO &gt; 1) and metachronous metastasis were independent prognostic factors. In the metastatic nasopharyngeal carcinoma patients, the median overall survival was 13 months (1–156 months). In multivariate analysis, independent prognostic factors were non-oligometastatic disease, severe (G3–G4) chemotherapy toxicity and the lack of nasopharyngeal and metastatic site irradiation. In the metachronous metastatic nasopharyngeal carcinoma patients, the median overall survival was 7 months (1–41 months). In multivariate analysis, the poor performance status (WHO &gt; 1) was an independent metastatic nasopharyngeal carcinoma prognostic factor. Conclusion: Oligometastatic patients with synchronous metastatic nasopharyngeal carcinoma had better survival. The locoregional treatment of primitive nasopharyngeal carcinoma improved survival in patients with metastatic nasopharyngeal carcinoma who responded to induction chemotherapy. Local irradiation of metastatic sites improved survival of metastatic nasopharyngeal carcinoma patients. Grade 3 or 4 chemotherapy toxicity altered survival among patients with synchronous metastatic nasopharyngeal carcinoma.

title: Simultaneous GC-NCI-MS Determination of Persistent Organic Pollutants and Current-Use Pesticides in Breast Milk Samples

description: To preserve human health, persistent organic pollutants (POPs) and current-use pesticides (CUPs) should be monitored in fatty tissues, including breast milk. Therefore, this study aimed to optimize sample preparation conditions using a 32 factorial design for the determination of POPs and CUPs by gas chromatography coupled to mass spectrometry with negative chemical ionization (GC-NCI-MS). The method was validated for 57 POP and CUP compounds using hexane:acetone for extraction and clean-up by dispersive solid phase extraction (d-SPE) with Florisil®. The matrix effect was compensated by extracted analytical calibration. Method validation showed satisfactory results with limits of detection of 3 to 13 ng g-1 of fat. The method presented adequate accuracy (recoveries from 72 to 117%) and precision (relative standard deviation (RSD) ≤ 18%) and was applied to breast milk samples from Rio Grande do Sul State, southern Brazil, wherein all samples contained at least one compound. With principal component analysis, it was possible to associate the pesticides detected with the city of origin of the samples and the number of pregnancies of nursing mothers. Additionally, the analytical method was effective for the determination of trace levels of POPs and CUPs in breast milk and can be applied in biomonitoring studies.

title: Early term ocular changes after cold compress application

description: ABSTRACT Purpose: To examine changes in the eyes after cold compress application at the early stage. Method: A total of 62 eyes from 62 healthy adult participants were included in this cross-sectional and comparative study. The subfoveal choroidal thickness and retinal nerve fiber thickness were measured by spectral-domain ocular coherence tomography. The central corneal thickness, anterior segment volume and depth, iridocorneal angle, and pupil diameter were measured by means of the Scheimpflug anterior segment imaging method. The measurements were repeated after 10 min of cold compress application, which was applied using special packs. The procedures were then repeated with non-cold packages to exclude the effect of pressure. Results: The average age of the participants was 30.74 ± 5.82 years. There was no significant change in the central corneal thickness after cold compress application, and there was a significant decrease in the anterior segment volume (p&lt;0.001), anterior segment depth (p&lt;0.001), and pupil diameter. Moreover, the iridocorneal angle increased (p=0.002). The subfoveal choroidal thickness decreased after the application of cold compress (p&lt;0.001). The overall disk thickness (p=0.034) and superior nasal scale (p=0.007) significantly decreased after the cold compress was administered during the evaluation of optic nerve fiber thickness. In contrast to that with the cold application, the subfoveal choroidal thickness and optic nerve fiber thickness did not change after the non-cold compress application (p&gt;0.05). Conclusion: Cold compress application may thus cause some physiological changes in the eyes, which necessitates the examination of its usage and effects.
