Giant basal cell carcinoma of the nasal pyramid - case report.

Basal cell carcinoma (BCC) is a frequent form of skin cancer, which usually affects people that have been exposed to the sunlight for longer periods of time. The cells of the lower part of the epidermis are called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skin's surface.

Complications related to breast reconstruction after mastectomy using multiple surgical techniques - a national and international comparative analysis.

The present paper describes and analyzes complications related to alloplastic breast reconstruction, as well as those associated with surgical techniques involving myocutaneous flaps. The article also contains a comparative analysis of the results obtained with the data in the international specialized literature. The statistical analysis is primary based on data obtained from patients included in the National Breast Reconstruction Program developed within the "Bagdasar-Arseni" Emergency Clinical Hospital, Bucharest, Romania, between 2015 and 2019.

Osseointegration of chemically modified sandblasted and acid-etched titanium implant surface in diabetic rats: a histological and scanning electron microscopy study.

Introduction: The aim of this study is to assess the osseointegration of different dental implants surfaces in diabetic rats.

Materials And Methods: In this study, were used 56 male Wistar rats, average weight of 300-350 g. Diabetes was induced by a single intraperitoneal injection of Streptozotocin.

Cytological, histopathological and immunological aspects of autoimmune thyroiditis: a review.

Autoimmune thyroiditis (AT) is a disease that may be associated with many other autoimmune endocrine and non-endocrine disorders. This disease is mediated by both humoral and cellular mechanisms and it is the result of combined effects of human leukocyte antigen (HLA) class II genes and non-HLA genes polymorphisms. The clinical course of AT is variable and may be characterized by spontaneous remission and by irreversible thyroid insufficiency as the consequence of atrophic and fibrous transformation of the thyroid gland in other cases.

Longer survival of a patient with glioblastoma resected with 5-aminolevulinic acid (5-ALA)-guided surgery and foreign body reaction to polyglycolic acid (PGA) suture.

In recent years, there is a growing evidence that using 5-aminolevulinic acid (5-ALA)-guided resection of a cerebral glioblastoma, associated with chemoradiotherapy determine a prolonged survival of these patients, even though this period do not exceed 15 months. 5-ALA is a natural biochemical precursor of heme that is metabolized to fluorescent porphyrins, particularly protoporphyrin IX (PPIX) and no foreign reaction were noted until now. However, foreign body reaction developing in neurosurgery is documented in a few number of cases to suture material, surgical hemostatic material, or surgical glove starch, but up to now we could not find any article about granulomatous inflammation to polyglycolic acid (PGA) suture after brain tumor resection.

Histological, immunohistochemical and clinical considerations on amniotic membrane transplant for ocular surface reconstruction.

Amniotic membrane (AM) transplantation has been used successfully worldwide in ophthalmology plastic surgery for over 100 years. This review presents the histological and the immunohistochemical features of AM compared to those of the conjunctiva and discusses the techniques of processing and preservation, its mechanism of action in ocular reconstruction, its clinical ophthalmic indications, but also advantages and limitations of grafting with this biomaterial.

Long-term survival in a patient with advanced gastric cancer and metachronous right-sided colon cancer.

Gastrointestinal carcinomas represent the most common cancers worldwide. The coexistence of gastric cancer with metachronous colon cancer represents a rare phenomenon, and the prognosis of the patient is poor. We present here a case of an elderly patient with primary gastric intestinal type well-differentiated adenocarcinoma (pT3N0, stage IIA) who developed a metachronous right-sided colon cancer diagnosed and treated after 11 years from the first surgical intervention.

Invasive keratinizing squamous cell carcinoma of the left external auricular canal and the middle ear - case report.

The rather low incidence of auricular neoplasms irrespective of localization is likely to cause confusion of diagnosis with the more frequent benign ear pathology. Because of this, the elapsed time until confirmation of the diagnosis facilitates the evolution of the disease to the detriment of the patient's health. The diagnosis of an ear neoplasm can hide under the ordinary appearance of external otitis, chronic otorrhea or episodes of various types of ear pain.

Histopathological consequences of hyperzincemia on rat teeth. Experimental study.

The aim of this study was to investigate the histopathological features of dental pulp in acute zinc (Zn) intoxication and to identify possible physiopathological mechanisms of the lesions. Twelve adult male Wistar rats were divided into two groups, the control one and the exposed group. Each animal from the experimental group received a single dose of zinc chloride (ZnCl2) by intraperitoneal injection.

Intraventricular metastatic clear cell renal carcinoma.

Background: Intraventricular tumors represent a diagnostic problem, due to a wide range of differential diagnosis, with an important variability of tumoral histological types in adult and pediatric population. Patient,

Methods And Results: Our case is represented by a patient, aged 48 years, without any history of significant personal pathology, accusing nausea, vomiting, and intensive headache. In the morning, he became confused, having hallucinations for a short period of time, and has accused drowsiness for several weeks.

The Fahr syndrome and the chronic lymphocytic thyroiditis.

Fahr syndrome (FS) refers to basal ganglia calcification that is associated with many neurological and psychiatric abnormalities and appears as secondary to other diseases. We described a case of FS patient who was admitted in the Department of Neurology of "Prof. Dr.

Morphological assessments on the arteries of the superior renal segment.

The study was performed on 461 renal arteries in order to assess some morphological aspects regarding the arteries that supply the superior renal segment using as study methods: dissection, injection of contrast medium, injection of plastic followed by corrosion together with the examination of MRI and renal angiographies (simple and angio CT). The posterior arteries of the superior renal segment originate mostly from the posterior terminal branch of the renal artery as 1-3 arterial branches. In only 42 cases, we found posterior branches that do not participate in the supply of the superior renal pole.

The morphology and the surgical importance of the gonadal arteries originating from the renal artery.

Using dissection and plastic injection followed by corrosion as study methods, we describe 16 cases of gonadal arteries originating from the renal artery. Among them, in 12 cases (75%), we assessed this variation on a single gonadal artery while two gonadal arteries appeared in four cases (25%). In 13 cases (81.

[The origin and distribution of retro-pyelic artery].

We used as study methods of retro-pyelic artery: dissection on adult human bodies and on human fetuses, injection of plastic material followed by corrosion and the study of selective and total renal nephroangiography. We've studied the origin, the termination way and vascularization territory of retro-pyelic artery on 208 cases. We found retro-pyelic artery origin to have 3 arterial sources: as terminal branch of renal artery (58.

[Anatomical considerations on the renal arterial segmentation].

We studied the arterial segmentation of the kidney observing the basic mode of finishing of the renal arteries and the distribution of the second order arteries in renal parenchyma. Our study was performed on 194 human kidneys resulted by evisceration and we have also analyzed the renal angiographies. As methods of study we used dissection, injection of plastic material followed by corrosion.
