Novel technique of development of human derived acellular dermal matrix.

Reconstructive surgery techniques have evolved exponentially in last decades. From regional flaps to free tissue transfer, tissue movilization has become the gold standart treatment in many reconstructive procedures. Main disadvantage from these techniques lies in the possibility of sequels in donor zone.

[Minimally invasive percutaneous musculoskeletal biopsy performed by Interventional Pathologist for myopathy study. Twenty years of experience].

Introduction: Muscle biopsy plays a major role in the final diagnosis of myopathies. Open muscle biopsy is the benchmark procedure, although minimally invasive percutaneous muscle biopsy (MIPMB) has demonstrated comparable diagnostic performance at a lower cost and can be carried out by interventional pathologists.

Materials And Methods: Muscle biopsies performed from 1997 to 2017 were reviewed and classified according to the type of procedure, whether carried out by an interventional pathologist or another specialist, the diagnosis and the effectiveness of the procedure.

Practical application of stereological methods in experimental kidney animal models.

The kidneys are vital organs responsible for excretion, fluid and electrolyte balance and hormone production. The nephrons are the kidney's functional and structural units. The number, size and distribution of the nephron components contain relevant information on renal function.

"Posterior fossa lesion 45 years after ocular trauma".

We describe a patient who developed an isolated brain metastasis four years after his right eye was treated for conjunctival melanoma by excision and local chemotherapy. He had a history of ipsilateral ocular trauma by coal stuff while working in a mining industry. Conjunctival melanoma represents only 1.

Brain death effects on catecholamine levels and subsequent cardiac damage assessed in organ donors.

Background: Brain death (BD) causes hemodynamic and neuroendocrine alterations including a catecholamine surge, which in turn causes histologic lesions in cardiac muscle such as contraction bands, focal mononuclear cell infiltrates and cardiomyocyte necrosis. These changes are likely to compromise heart function and could therefore also affect the graft response after heart transplantation. This study was designed to examine the catecholamine surge, the catecholamine release pattern and the histologic lesions traditionally described as characteristic of BD in hearts procured from BD donors.

72 year-old man with new seizure while dancing.

Metastasis of an extracranial malignant neoplasm to a meningioma is a rare event.We report a case of a 72-year-old man who presented abruptly with a grand mal seizure. Neuroradiological examination revealed an extraaxial lesion located in the posterior right frontal convexity with poorly defined boundaries.

A molecular approach to apoptosis in the human heart during brain death.

Background: Brain death induces changes in tissues and organs destined for transplant at the cell, molecular, and endocrine level including cell death through apoptosis. This study was designed to examine apoptotic damage in cardiac tissue obtained from brain dead donors.

Methods: Fifty tissue specimens from the left ventricles of individual donors were processed to evaluate changes in the expression levels of five genes involved in apoptosis (BAX, BCL2, CASPASE 3, CYTOCHROME C, and FAS) using the real time-polymerase chain reaction technique.

Histologic findings and comparison with sputum smears in pulmonary aspiration of vegetable particles in syringomyelia: a case report.

Background: Pulmonary aspiration of vegetable matter may be a serious cause of lung damage, requiring, almost always, the help of a histopathologic examination.

Case: We report the case of a 55-year-old woman with a granulomatous pneumonitis due to repeated pulmonary aspiration of vegetable particles and affected by a syringomyelia. Histologic findings from a lobectomy section are shown and compared with those observed in different cytologic sputum samples.

Fine needle aspiration cytology of focal myositis: a case report.

Background: Focal myositis is an unusual inflammatwy lesion of the skeletal muscle first described by Heffizer. It is a benign condition and usually involves the muscles of the limbs.

Case: A man presented with a palpable mass in the left leg of 6 months' duration.
