Altered elemental profile as indicator of homeostatic imbalance in pathogenesis of oral submucous fibrosis

2002

Oral submucous fibrosis (OSF) is a potential precancerous condition of the oral cavity and oropharynx. The etiopathogenesis of this complex precancerous condition is still obscure. In addition to deleterious oral habits, malnutrition, and possible genetic predisposition, altered bioelemental status is also likely to play an important role in its pathogenesis. The present study analyzed 68 elements by inductively coupled plasma-mass spectroscopy in oral mucosa of normal and OSF individuals and some interesting alterations in elemental profile in the diseased tissue have been noted, indicating a homeostatic imbalance. These bioelemental alterations leading to homeostatic imbalance might be co…

Dupuytren's contracture: an update of biomolecular aspects and therapeutic perspectives.

2005

The so-called fibrogenic cytokines, able to induce the growth of fibroblasts and their differentiation into myofibroblasts and to stimulate their production of extracellular matrix, are involved in the genesis of Dupuytren’s contracture. Although many studies have been made of biomolecular aspects of palmar fibromatosis, practical applications from them are still far from imminent because of the real difficulty of blocking their action in vivo, even in a chronic, progressive lesion such as Dupuytren’s disease. Consequently, surgical excision of the palmar fascia still remains the treatment of choice.

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…

Assessment of prurigo of pregnancy in patients without atopic background

2020

Highlights • PP can develop in patients without atopic background. • Onset: late 2nd to early 3rd trimester; can persist until delivery. • Patient should be counseled accordingly. • These findings should be considered when classifying specific pregnancy dermatoses.

Autosomal recessive polycystic kidney disease: case report of a newborn with rare PKHD1 mutation, rapid renal enlargement and early fatal outcome

2020

Abstract Introduction Autosomal recessive polycystic kidney disease (ARPKD; MIM#263200) is one of the most frequent pediatric renal cystic diseases, with an incidence of 1:20,000. It is caused by mutations of the PKHD1 gene, on chromosome 6p12. The clinical spectrum is highly variable, ranging from late-onset milder forms to severe perinatal manifestations. The management of newborns with severe pulmonary insufficiency is challenging, and causes of early death are sepsis or respiratory failure. In cases of massive renal enlargement, early bilateral nephrectomy and peritoneal dialysis may reduce infant mortality. However, there is no conclusive data on the role of surgery, and decision-makin…

Febrile seizure and related syndromes

2018

Abstract Febrile seizures (FS) are the result of particular sensitivity to fever in the developing brain, have a major genetic predisposition, and nearly always have a benign outcome. Febrile seizures are the most common for of seizures in childhood. They have been observed in 2–6% of children before the age of 5 years, but in some populations this figure increase to 15%. Febrile seizures could be the first manifestations of epilepsy. About 13% of epileptic patients have a history of febrile seizures, and 30% have had recurrent febrile seizures Their phenotypic characteristics allow, in the majority of cases, a classification of the seizure, an elaboration of a prognosis and to assume a spe…

Brief report: Assessing dispositional optimism in adolescence – Factor structure and concurrent validity of the Life Orientation Test – Revised

2014

Dispositional optimism is an individual difference promoting psychosocial adjustment and well-being during adolescence. Dispositional optimism was originally defined as a one-dimensional construct; however, empirical evidence suggests two correlated factors in the Life Orientation Test - Revised (LOT-R).The main aim of the study was to evaluate the dimensionality of the LOT-R. This study is the first attempt to identify the best factor structure, comparing congeneric, two correlated-factor, and two orthogonal-factor models in a sample of adolescents. Concurrent validity was also assessed.The results demonstrated the superior fit of the two orthogonal-factor model thus reconciling the one-di…

Disposition ofd-penicillamine, a promising drug for preventing alcohol-relapse. Influence of dose, chronic alcohol consumption and age: studies in ra…

2014

Pharmacokinetic studies concerning d-penicillamine (an acetaldehyde sequestering agent) are scarce and have not evaluated the influence of chronic ethanol consumption and age on its disposition. Since recent preclinical studies propose d-penicillamine as a promising treatment for alcohol relapse, the main aim of the present work was to evaluate the influence of these two factors on d-penicillamine disposition in order to guide future clinical studies on the anti-relapse efficacy of this drug in alcoholism. Additionally, the effect of the administered dose was also evaluated. To this end, three studies were carried out. Study 1 assessed the influence of dose on d-penicillamine disposition, w…
