Intra-mandibular adenoid cystic carcinoma.

2013

Intra-mandibular localization of adenoid cystic carcinoma is rare. This tumor is characterized by progressive local, regional, and distant aggressiveness. We reviewed the latest data on this rare type of cancer with a small number of reported cases, alack of consensus for its treatment, and its bad prognosis.

Reduction of Interstitial Cells of Cajal (ICC) Associated With Neuronal Nitric Oxide Synthase (n-NOS) in Patients With Achalasia

2007

The etiology of achalasia is still unknown. The current theories of chronic inflammation leading to autoimmune response with destruction and loss of the inhibitory myenteric ganglion cells enlighten its pathogenesis in a limited way only. Interstitial cells of Cajal (ICC) have been shown to be involved in nitrergic neurotransmission of the lower esophageal sphincter (LES).To investigate the significance of ICC and neuronal nitric oxide synthase (n-NOS) in esophageal wall tissue of patients undergoing surgery for achalasia.In 53 patients with a median age of 45 (6-78) yr undergoing surgery for achalasia, the immunoreactivity of ICC (CD117/c-kit) and n-NOS was assessed. In 42 patients, biopsi…

Survival of patients with lymphoplasmacytic lymphoma and solitary plasmacytoma in Germany and the United States of America in the early 21st century

2017

Population-level survival has increased for a number of hematologic malignancies.[1][1]–[3][2] Multiple myeloma, in particular, has seen improved survival both in clinical trials[4][3]–[8][4] and on the population level.[3][2],[9][5]–[11][6] However, it is not known whether the changes in

Granulomatous slack skin: report of a case associated with Hodgkin's disease and a review of the literature.

1994

We report a case of granulomatous slack skin (GSS) associated with Hodgkin's disease, and review the literature on this entity. GSS, a variant of cutaneous T-cell lymphoma, clinically presents with erythematous patches in the flexures, which gradually transform into bulky, pendulous areas of skin. Histology shows an elastolytic granulomatous infiltrate, with atypical lymphoid cells, and occasional epidermotropism. As far as we are aware, 10 cases of GSS, including our patient, have been reported in detail. The male:female ratio of these cases is 9:1, and the age range 15-51 years. Five cases were associated with Hodgkin's disease, one with small lymphocytic lymphoma, and one developed cutan…

Study of microcirculation in oral lichen planus by video-capillaroscopy.

2007

Objective The aim of this study was to evaluate “in vivo” the oral microcirculatory characteristics in patients with oral lichen planus (OLP) and to discover any differences in microcirculation in comparison with healthy patients. Study design Twenty patients with established diagnosis of OLP and 20 healthy patients were examined in our laboratory by means of contact optical probe videocapillaroscopy. The examined areas for each patient were the right and the left buccal mucosae. Capillary density and total capillary diameter, as well as afferent and efferent loop diameter were studied; the discovery of characteristic (tortuous, branched) loops was also investigated. Results The results wer…

Functional, biochemical and morphological studies on human bronchi after cryopreservation

1995

1. Human isolated bronchi have been investigated as fresh tissue or after storage (7 and 30 days) at -196 degrees C in foetal calf serum containing 1.8 M dimethyl sulphoxide. 2. After cryopreservation, the maximal contractile response to acetylcholine (3 mM) was reduced (approximately 25%) but the difference did not reach significance statistically. Maximal responses to other spasmogens tested (histamine, [Nle10]NKA(4-10), bradykinin, leukotriene D4, U46619, and KCl) did not differ between unfrozen and frozen/thawed tissues. The sensitivity of cryopreserved tissues to the constrictor agents tested was similar to that of fresh tissues. 3. The accumulation of inositol phosphates produced by a…

Associations between infant and maternal characteristics measured at child age 5 months and maternal feeding styles and practices up to child age two…

2022

Facilitating positive feeding practices from infancy may be an important strategy to prevent childhood overweight and obesity. Since the feeding situation early in life constitutes a bidirectional relationship, it is important to understand the impact of both maternal and infant characteristics on maternal feeding practices to intervene in a customized and tailored way. Few studies have concurrently examined associations between maternal and infant characteristics in relation to early maternal feeding practices. The aim of the present study was to explore potential associations between infant and maternal characteristics measured at child age five months, and maternal feeding styles and pra…

As Long as the Breath Lasts: In Utero Exposure to Ramadan and the Occurrence of Wheezing in Adulthood.

2017

While prenatal exposure to Ramadan has been shown to be negatively associated with general physical and mental health, studies on specific organs remain scarce. In this study, we explored whether Ramadan exposure during pregnancy affects the occurrence of wheezing, a main symptom of obstructive airway disease. Using data from the Indonesian Family Life Survey collected between 1997 and 2008 (waves 2-4), we compared wheezing occurrence among adult Muslims who had been in utero during Ramadan with that in adult Muslims who had not been in utero during Ramadan. Wheezing prevalence was higher among adult Muslims who had been in utero during Ramadan, independent of the pregnancy phase in which t…

Optimizing strategies for meningococcal C disease vaccination in Valencia (Spain)

2014

Background: Meningococcal C (MenC) conjugate vaccines have controlled invasive diseases associated with this serogroup in countries where they are included in National Immunization Programs and also in an extensive catch-up program involving subjects up to 20 years of age. Catch-up was important, not only because it prevented disease in adolescents and young adults at risk, but also because it decreased transmission of the bacteria, since it was in this age group where the organism was circulating. Our objective is to develop a new vaccination schedule to achieve maximum seroprotection in these groups. Methods: A recent study has provided detailed age-structured information on the seroprote…
