Prosthetic rehabilitation with dental implants after treatment of a keratocystic odontogenic tumor. Case report

2011

Keratocystic odontogenic tumor (KCOT), formerly known as the odontogenic keratocyst (OKC) is a benign intraosseous lesion, characterized by invasive growth and high rate of recurrences. Although it is not frequently seen, KCOT may be associated with unerupted teeth and without relevant histopathological examinations, might be mistaken with dentigerous cyst. A 26 year-old male patient referred to our department with complaints of two months persisting painless swelling on the left side of mandible. Clinical and radiographic examinations revealed an impaction of the horizontally positioned left lower second premolar surrounded by a well-circumscribed radiolucent mass, located between the left…

Gastrin: an acid-releasing, proliferative and immunomodulatory peptide?

2010

Gastrin release is affected by gastric inflammatory conditions. Antral G cells respond to inflammatory mediators by increasing gastrin secretion. Accumulating experimental evidence suggests that gastrin exerts immunomodulatory and proinflammatory effects. Gastrin could be a contributing factor to these pathologies, which may constitute a new justification for pharmacological blockade of gastrin action.

Histopathologic Findings in Early Encapsulated Blebs of Young Patients Treated With the Ahmed Glaucoma Valve

2010

Objective/aim Uncontrolled glaucoma presents a challenge for the ophthalmic surgeon especially in children and juvenile patients. For many patients who have undergone failed surgical procedures before, episcleral implants remain the last choice. Encapsulated blebs forming over antiglaucoma devices present a complication leading to malfunctioning or even failure with reincrease in intraocular pressure. We report our histopathologic findings of such blebs developing around the Ahmed glaucoma valve (AGV) after a short time period in young patients. Materials and methods Nine young patients (2 to 17 y of age) with otherwise uncontrollable glaucoma were treated with AGV (models FP-7 and FP-8, si…

Iodide Mumps After Intravenous and Oral Administration of Contrast Medium

1996

A 70-year-old woman with a history of radical cystectomy and continent urinary diversion with a Mainz pouch I due to muscle invasive bladder carcinoma presented for a routine evaluation. Physical examination, electrocardiogram, chest x-ray and routine laboratory values showed no pathological findings. There was no history of salivary gland disease. Excretory urography was performed with 100 ml. nonionic contrast medium (iopromide) injected intravenously. Painless bilateral swelling of the submandibular glands developed 16 hours later without any dysphagia, dyspnea or other allergic reactions (see figure). After systemic treatment with an antihistamine and prednisolone the swelling resolved …

Leptin and Leptin Receptor Are Expressed in the Human Endometrium and Endometrial Leptin Secretion Is Regulated by the Human Blastocyst1

2000

Embryonic implantation is a crucial event for the human reproductive function. Cytokines and paracrine molecules have been proposed as putative local regulators of this process. The leptin or the OB protein has been linked to the reproductive function and inflammatory response. In the present study, we describe for the first time the expression of leptin and leptin receptor (long form) in the secretory endometrium and that endometrial leptin secretion is regulated in vitro by the human blastocyst. Leptin and leptin receptor messenger RNA and protein were identified in secretory endometrium and in cultured endometrial epithelial cells (EECs) by RT-PCR, Western blot, and immunohistochemistry.…

Elevated Expression of Liver γ-Cystathionase Is Required for the Maintenance of Lactation in Rats

1999

Liver gamma-cystathionase activity increases in rats during lactation; its inhibition due to propargylglycine is followed by a significant decrease in lactation. This is reversible by N-acetylcysteine administration. To study the role of liver gamma-cystathionase and the intertissue flux of glutathione during lactation, we used lactating and virgin rats fed liquid diets. Virgin rats were divided into two groups as follows: one group was fed daily a diet containing the same amount of protein that was consumed the previous day by lactating rats (high protein diet-fed rats); the other virgin group was fed the normal liquid diet (control). The expression and activity of liver gamma-cystathionas…

Atypical radiological presentation of multiple cystic brain metastases from lung cancer simulating neurocysticercosis.

2019

Brain metastases (BMs) are usually characterised by vasogenic oedema and mass effect, but cystic appearance can rarely occur, mimicking parasitosis, such as neurocysticercosis (NCC). A woman in her mid-50s was admitted for dizziness and upper left extremity paresis. Neuroimaging showed multiple cystic lesions consistent with multiple stages of NCC evolution, and empiric albendazole was started, without any clinical improvement. A whole-body CT revealed a pulmonary lesion in the right superior lobe. Pathological analysis from brain specimen demonstrated a clear cell lung carcinoma. The patient gradually worsened and died 4 months after the diagnosis. In conclusion, multiple cystic BMs are an…

Structured Reporting of Solid and Cystic Pancreatic Lesions in CT and MRI: Consensus-Based Structured Report Templates of the German Society of Radio…

2020

 Radiological reports of pancreatic lesions are currently widely formulated as free texts. However, for optimal characterization, staging and operation planning, a wide range of information is required but is sometimes not captured comprehensively. Structured reporting offers the potential for improvement in terms of completeness, reproducibility and clarity of interdisciplinary communication. Interdisciplinary consensus finding of structured report templates for solid and cystic pancreatic tumors in computed tomography (CT) and magnetic resonance imaging (MRI) with representatives of the German Society of Radiology (DRG), German Society for General and Visceral Surgery (DGAV), working grou…

Accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis: review of the literature.

2013

Background To evaluate the accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis in comparison with other imaging modalities. Methods The authors performed a search of the Medline/ PubMed (National Library of Medicine, Bethesda, Maryland) for original research and review publications examining the accuracy of ultrasonography in the diagnosis of acute calculous cholecystitis. The search design utilized a single or combination of the following terms : (1) acute cholecystitis, (2) ultrasonography, (3) computed tomography, (4) magnetic resonance cholangiopancreatography and (5) cholescintigraphy. This review was restricted to human studies and to English-language literat…
