QUANTIFICATION OF NEURAL ELEMENTS IN POSTERIOR CRUCIATE LIGAMENT: COMPARISON BETWEEN HEALTHY KNEES AND WITH PRIMARY OSTEOARTHROSIS.

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.

Study on collagen parameters in vulvar cancer and preneoplastic lesions by Second Harmonic Generation microscopy.

The extracellular matrix plays an important role in cellular balance, and collagen fibers are its most important component. 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.

Congenital Zika Syndrome: The Main Cause of Death and Correspondence Between Brain CT and Postmortem Histological Section Findings From the Same Individuals.

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.

Fat deposition in the left ventricle: descriptive and observacional study in autopsy.

Background: The human heart contains varying amounts of fat deposits. Cardiac physiological fat occurs predominantly in the right ventricle (RV). The discovery and characterization of adipose tissue along the left ventricle (LV) has been rarely reported.

[Assessment of Service to verify the cause of death implementation in Pernambuco State, Brazil, 2012: multiple case study].

Objective: to evaluate the implementation of Death Verification Services in Pernambuco State, Brazil, in 2012.

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.

A comparative study of the areas of osteochondral defects produced in femoral condyles of rabbits treated with sugar cane biopolymer gel.

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.

Effectiveness of histology and cytology on musculoskeletal tumor diagnosis.

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.

Neoplasm seeding in biopsy tract of the musculoskeletal system. A systematic review.

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.

TUMOR CONTAMINATION IN THE BIOPSY PATH OF PRIMARY MALIGNANT BONE TUMORS.

Objective: To study factors possibly associated with tumor contamination in the biopsy path of primary malignant bone tumors.

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.

[Left and right ventricular hypertrophy at autopsy of hypertensive individuals].

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 role of cytology in the diagnosis of musculoskeletal neoplasms: systematic review.

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.

Comparative study of the areas of osteochondral defects produced in the femoral condyles of rabbits treated with gel of sugarcane biopolymer.

Purpose: To measure the healed areas of osteochondral defects produced in femoral condyles of rabbits filled with biopolymer sugar cane gel and to compare these with those of the control group at 90, 120 and 180 days.

Methods: A study was made of 16 New Zealand rabbits, 6 and 7 months old, weighing between 2 and 2.5 kg.

COMPARATIVE MACROSCOPIC STUDY OF OSTEOCHONDRAL DEFECTS PRODUCED IN FEMURS OF RABBITS REPAIRED WITH BIOPOLYMER GEL CANE SUGAR.

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.

HPV and precancerous lesions of anal canal in women: systematic review.

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.

Quantitative study of Langerhans cells in basal cell carcinoma with higher or lower potential of local aggressiveness.

Backgrounds: Basal cell carcinoma affects areas of the body that have been exposed to the sun, and this disorder has different clinical and histopathologic presentations. Some of these forms have a higher potential of local aggressiveness, while others have a lower potential. Langerhans cells actively participate in the skin immune system.
