Efficacy of intra-arterial lidocaine infusion in the treatment of cerulein-induced acute pancreatitis

2020

Background Disturbances in pancreatic microcirculation, beginning with vasoconstriction, are crucial in early pancreatitis and progression to necrotizing pancreatitis. Thus, vascular-targeted treatment aiming to restore a sufficient level of microcirculation through vasodilation would possibly reduce the severity of pancreatitis. Lidocaine is an anti-arrhythmic and local anesthetic drug, which also acts as a vasodilator at higher concentrations. Objectives To evaluate the efficacy of intra-arterial infusion of lidocaine into the celiac trunk in treatment of cerulein-induced acute pancreatitis. Material and methods Wistar rats (n = 20) were randomly divided into 2 equal groups: the control g…

Lung nodule 25 years after lobectomy - recurrence of bronchial carcinoid

2020

OBJECTIVE Introduction: Bronchopulmonary (BP) carcinoids are low and intermediate grade tumors, seen in adults between fourth to sixth decade, where no clear association with tobacco smoking is established. Most often they are sporadic lesions (95%). Half of patients have no symptoms and the tumor is incidentally found on a chest x- ray. BP carcinoids have a good prognostic, however there is a risk of distant metastasis and the recurrences are frequent. Therefore a crucial role of vigilant follow- up, extending far beyond 5 years. PATIENTS AND METHODS Case presentation: We report a case of 73 years old women, with history of recurrent pulmonary infections, and positive family history for lu…

Is immunohistochemical evaluation of p16 in oropharyngeal cancer enough to predict the HPV positivity?

2016

Abstract Aim Our goal was to determine the expression levels of p16 in the cohort of the OPSCC patients and evaluation of the pathological and clinical differences between these two groups including patients’ survival. Background HPV infection is the main causative factor of oropharyngeal cancer (OPSCC). Identification of HPV status in OPSCC requires positive evaluation of viral DNA integration into host cell however, p16 accumulation in the proliferating cell layers has been accepted as an alternative marker for HPV infection. Material and Methods The IHC staining for p16 has been performed in tumor tissue from 382 OPSCC patients. The sample was considered positive based on more than 70% o…

Correlation study of GAPDH, Bcl-2, and Bax protein immunoexpression in patients with colorectal adenocarcinoma.

2018

Introduction Colorectal cancer (CRC) is the third and second most commonly diagnosed cancer worldwide in males and females, respectively. Despite prominent progress in diagnosis and treatment, the recurrence rates are still high. A tumour hypoxic environment leads to an increase in glycolytic metabolism. The crucial intermediate component of glycolysis, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), could play a significant role in cancer progression. An increased level of GAPDH has been described in oncogene-induced transformation and anti-apoptotic function. In other studies, GAPDH has been involved in apoptosis induction. Aim We examined colorectal adenocarcinoma samples to assess the…

Odontogenic fibroma — a case report

2014

Abstract IThe present study outlines the case of a 30-year-old patient with central odontogenic fibroma. The tumour developed in the alveolar process of the maxilla in the area of 13–15. The study describes the clinical symptoms, the radiological image, treatment method and histopathological image of the tumour. The study also presents a one-year period of post-surgical observation.

Efficacy of photodynamic therapy in vulvar lichen sclerosus treatment based on immunohistochemical analysis of CD34, CD44, myelin basic protein, and …

2010

Introduction:Lichen sclerosus (LS) is a chronic skin and mucosa inflammatory disease. It affects mainly the female anogenital area especially in postmenopausal period. The main symptoms include pruritus, burning, pain, sometimes urinary problems, or difficulties in defecation. Usually, porcelain-white plaques are seen in the skin and mucosa. The etiology and pathogenesis of LS are still uncertain. There are some research studies on possible genetic predisposition, yet autoimmune, hormonal, or infectious factors are not excluded. The typical treatment of LS is mainly pharmacological, although the alternative treatment method used in LS is photodynamic therapy (PDT), which is noninvasive tech…

Histopathological pulmonary findings of survivors and autopsy COVID-19 cases: A bi-center study

2022

The coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), evolved into a global pandemic. As ACE2 on the surface of alveolar cells of the lung epithelium is one of the potential target receptors for SARS-CoV-2, the respiratory symptoms are the most common presentation of COVID-19. The aim of our study was to investigate the morphological findings in lung tissue after being infected by SARS-CoV-2 and compare histopathologic changes in patients with COVID-19 infection history who died to those who survived. We analyzed lung tissue samples from 9 patients who died from COVID-19 and from 35 patients with COVID-19 infection history who survi…

Synchronous Two Distinct Neuroendocrine Lung Cancer Lesions

2015

Synchroniczne nowotwory płuc są rzadką chorobą, a prezentowany przypadek to pierwszy opublikowany opis jednoczesnego wystąpienia dwóch pierwotnych neuroendokrynnych raków płuca zlokalizowanych w jednym płacie. Przedstawiono przypadek 55-letniej pacjentki z dwoma pierwotnymi, odrębnymi neuroendokrynnymi rakami płata górnego płuca prawego. Pacjentka została przyjęta na oddział chirurgii klatki piersiowej w celu diagnostyki dwóch cieni okrągłych płuca prawego (o średnicy 11 i 19 mm) uwidocznionych na zdjęciu RTG klatki piersiowej wykonanym trzy miesiące wcześniej. Przy przyjęciu pacjentka nie prezentowała żadnych objawów związanych ze zmianami w płucu. Dalsze badania obrazowe wykazały zmiennoś…

The importance of the concept and histological criteria of "intraepithelial squamous cell carcinoma" of the esophagus: in comparison between Western …

2017

Background There are differences in the histological diagnostic criteria for early stage gastrointestinal carcinoma between Western and Japanese pathologists. Western histological criteria of carcinoma are “presence of stromal invasion of neoplastic cells”, while Japanese criteria are “the degree of cytological and structural abnormality of neoplastic cells, regardless of stromal invasion”. The aim of the present study is to clarify and review the present status of the Western and Japanese histological criteria of early stage esophageal squamous cell carcinoma (SCC) and also to clarify their significance and accuracy. Methods Twenty-nine Polish, German, and Japanese pathologists participate…
