Background: Hesitation and refusal to take a second dose of the vaccine for coronavirus disease 19 (COVID-19) are prevalent.
Objectives: We aimed to identify predictive factors for hesitation or refusal and describe groups with higher rates of vaccine hesitancy.
Design And Setting: A cross-sectional study in Assis City, Brazil.
Objective: To quantify the neural elements in the posterior cruciate ligament (PCL) in healthy knees and with primary osteoarthrosis (OA).
Methods: In two groups with OA, one of cadavers and another of individuals, the area of neural elements identified in histological sections of PCL with anti-S100 immunohistochemistry was quantified.
Results: The overall mean area of the neural elements was 0.
BACKGROUND Nesidioblastosis is a rare disease that is part of the differential diagnosis of pancreatogenic hyperinsulinemic hypoglycemia (PHH) in patients whose imaging studies do not localize insulinoma. Pancreatic heterotopia is a rare congenital abnormality characterized by pancreatic tissue anatomically separated from the main gland and found in 0.5% of abdominal surgeries.

Over the last few years, second harmonic generation (SHG) microscopy has been used for the analysis of collagen fibers in several types of gynaecological cancers, such as breast and ovarian cancer. The value of collagen parameters obtained with this technique to gain insights on the physiopathology and on the prognostic evaluation of cancer has been advocated.

In the present case series, the cause of death of infants diagnosed with congenital Zika syndrome (CZS) was lung disease (pneumonia and sepsis with massive pulmonary aspiration), probably secondary to dysphagia and reflux. The main findings in infants with a confirmed diagnosis of CZS who died were as follows: (1) calcification and hypoplasia of the lentiform nuclei, hypoplasia of the caudate nuclei, and calcification at the cortical-subcortical junction was noted in all cases (100%) and calcification of the caudate nuclei was noted in 66.7% of cases; (2) calcification in the brainstem and along the lateral wall of the lateral ventricles was noted in only the case with arthrogryposis (33.

Methods: this was an implementation analysis evaluation study; we constructed a logical framework and judgement matrix were prepared; primary data (direct observation and interviews) and secondary data were used; assessment of the level of Death Verification Services implementation was based on outcome-related structure and process indicators which were compared with the logical framework.
Results: the Recife and Caruaru Death Verification Services were considered to have achieved Advanced Partial Implementation, consistent with the outcome indicators measured, reaching 89.

Purpose: To assess the histological response of damaged osteochondral tissue in the femoral condyles of rabbits after repairing the wounds with sugar cane biopolymer gel - compared to the control group.
Methods: The study investigated 16 New Zealand rabbits, at 90, 120 and 180 days after surgery. In all the animals, a lesion of 3.
Objective: To compare cytology and histology on the diagnosis of musculoskeletal neoplasms.
Method: Fifty eight cases available to evaluation were analyzed both by cytology and histology. The results of the biopsies studied by histology and cytology were compared to the results obtained on the surgical specimen or immunohistochemistry.
To identify, through a systematic literature review, the characteristics of neoplasm seeding in biopsy performed on the musculoskeletal system. We performed a search on PubMed, MEDLINE, LILACS and SciELO from August to October 2010. We included articles that addressed the neoplasm seeding in biopsy performed on the musculoskeletal system.

Method: Thirty-five patients who underwent surgical treatment with diagnoses of osteosarcoma, Ewing's tumor and chondrosarcoma were studied retrospectively. The sample was analyzed to characterize the biopsy technique used, histological type of the tumor, neoadjuvant chemotherapy used, local recurrences and tumor contamination in the biopsy path.
Objective: To measure the right and left ventricular thickness in deceased individuals with a history of hypertension submitted to clinical autopsies.
Methods: We selected 90 cases from the Death Verification Service of the city of Recife, state of Pernambuco, Brazil, of both sexes, with a history of essential arterial hypertension related to heart wall thickness, in addition to correlation with autopsy findings and other clinical reports.
Results: There was a significant association between the presence of left ventricular hypertrophy (LVH) and right ventricular hypertrophy (RVH) and between severe hypertensive cardiomyopathy and RVH.
The authors systematically reviewed the literature of the last decade on the role of cytology in the evaluation of musculoskeletal neoplasms, and its diagnostic accuracy. A search was carried out on the databases PubMed, MEDLINE, LILACS and SciELO, selecting articles in which cytology was used in the diagnosis of musculoskeletal neoplasms. Limits were used for English, Spanish and Portuguese, and only articles published since 2000 were selected.

Objective: To study the surface, coloring, consistency, continuity and healing of osteochondral defects produced in the femoral condyles of rabbits and filled with sugar cane biopolymer gel (SCBG), after 90, 120 and 180 days, and in comparison with a control group.
Method: Sixteen adult New Zealand white rabbits aged 6 to 7 months, weighing between 2 and 2.5 kg and without locomotor system abnormalities were studied.
Objective: The infection caused by human papillomavirus (HPV) in the anogenital area is considered the most common sexually transmitted infection in the world. Although anal cancer is relatively uncommon in the general population, there has been a significant increase in incidence in recent years. In this review, we focused on research on anal lesions in women.

In most series of neoplasms of the spinal canal, spinal cord and its leptomeninges, the incidence of meningioma group comprises approximately 25%. The incidence of multiple meningiomas is small when compared with the frequency of its single occurrence. In the majority of cases, their multiplicity is intracranial and spinal.
