[Early duodenal adenocarcinoma arising in gastric metaplasia treated by endoscopic resection].
2006
Duodenale Fruhkarzinome sind eine Seltenheit. Die meisten duodenalen Karzinome werden in einem fortgeschrittenen Stadium diagnostiziert. Wir berichten den Fall einer 59-jahrigen Patientin, welche zur weiteren Diagnostik und Therapie eines auswarts diagnostizierten duodenalen Fruhkarzinoms zu uns uberwiesen wurde. Die Osophagogastroduodenoskopie bei Aufnahme ergab eine Typ IIa+c-Lasion im proximalen Duodenum (10 - 12 mm grose zentral diskret eingesenkte Lasion). Mittels Chromo- und Magnifikationsendoskopie konnte die Lasion gut demarkiert und Veranderungen der Zottenarchitektur im Sinne einer Neoplasie gesehen werden. Nach Unterspritzung mit einer verdunnten Adrenalin-Losung konnte die Lasio…
The use of isolated caecal bowel segment in complicated vaginal reconstruction
2001
Objective To report a one-stage procedure, using a segment of caecum, both to overcome failed previous procedures and for primary vaginal replacement in patients with congenital vaginal aplasia, where primary reconstruction often results in vaginal obstruction and fistula formation. Patients and methods The vagina was reconstructed using a 15-cm isolated caecal segment placed between the bladder and rectum and anastomosed to the introitus. Between 1985 and 1997 the technique was used in 17 patients (mean age 23 years). Indications included congenital malformations and vaginal loss through anterior exenteration or trauma. Seven of the 17 patients had undergone previous complex reconstruction…

Single and Synergistic Effects of Type 2 Cytokines on Eosinophils and Asthma Hallmarks
2020
Abstract The type 2 cytokines IL-5, IL-13, and IL-4 play an important role in the induction and progression of asthma. According to the Global Initiative for Asthma guidelines, blood eosinophil numbers are one marker that helps to guide treatment decisions in patients suffering from severe forms of asthma. Effects of type 2 cytokines were analyzed, alone or in combination, on eosinophils in blood and other compartments and on the development of asthma symptoms. C57BL/6 mice received a single intranasal application of equimolar amounts of IL-5, IL-13, and IL-4, alone or in combination. Numbers, activation state, and migratory behavior of eosinophils in bone marrow (BM), blood, lung, and bron…

Condromatosis sinovial de la articulación temporomandibular: Estudio clínico, radiológico e histológico
2005
La condromatosis sinovial (CS) es una metaplasia cartilaginosa de los remanentes mesenquimales del tejido sinovial de las articulaciones. Se caracteriza por la formación de nódulos cartilaginosos en la sinovial y en la cavidad articular (cuerpos libres). La CS afecta sobre todo a grandes articulaciones sinoviales como la rodilla o el codo, siendo rara su aparición en la ATM, en donde tan solo 75 casos han sido publicados. Los síntomas predominantes son dolor, inflamación, limitación de los movimientos mandibulares y crepitación. Los métodos diagnósticos incluyen la ortopantomografía (OPG), la TC, la RM y la artroscopia de ATM. Presentamos un nuevo caso de CS unilateral de ATM, incluyendo la…
Predictive value of p53, Ki67 and TLR5 in neoplastic progression of Barrett’s esophagus: a matched case–control study
2022
Abstract Barrett’s esophagus progresses to high-grade dysplasia or cancer along the well-established metaplasia-dysplasia-adenocarcinoma sequence. The aim of this study was to evaluate the value of p53, Ki67, and toll-like receptor 5 (TLR5) in prediction of malignant progression of Barrett’s metaplasia and low-grade dysplasia. This was a retrospective matched case–control study based on Northern and Central Finland population. Patients diagnosed with esophageal high-grade dysplasia or adenocarcinoma were included. From these patients, all previous endoscopy samples were obtained along with original diagnostic HE-slides and clinical data. Age- and sex-matched patients with non-progressing Ba…
Lesioni cutanee stellate e simmetriche in un gemello “rimasto solo”
2021
The incidence of multiple pregnancy has increased, particularly because of the advances in assisted reproductive technologies. Multiple gestations are high risk pregnancies, especially the monochorionic ones. Two/thirds of initially twin pregnancies result in singles at birth, a condition defined as vanishing twin syndrome. The intrauterine death of one of the twins can cause direct fetal damage to the surviving one on several levels. The paper describes the case of a child born from twin pregnancy that was interrupted for one of the co-twins at early second trimester of gestation who presented with aplasia cutis congenita.
Sialometaplasia Necrotizante: Presentación de cinco casos clínicos
2004
La sialometaplasia necrotizante (SN) es una afección inflamatoria, autoresolutiva, que afecta a las glándulas salivales, más frecuentemente a las menores. Si bien su etiopatogenia permanece aún desconocida, diversos autores sugieren que una agresión fisico-química o biológica sobre los vasos sanguíneos produciría isquemia, la cual conduciría al infarto de la glándula y su posterior necrosis. Su aspecto clínico e histológico tiene apariencias de malignidad. Clínicamente puede presentarse como una úlcera de bordes irregulares, ligeramente elevados y lecho necrótico, mientras que histopatológicamente se caracteriza por presentar metaplasia escamosa de conductos y acinos e hiperplasia pseudoepi…
