A possible inflammatory reaction in a lateral neck cyst (branchial cyst) because of odontogenic infection

1994

Abstract We present the case of a woman who suffered from an acutely infected diffuse mass in the right neck. This mass had grown rapidly after difficult extraction of a tooth. Histologic analysis of the excised material revealed a lateral neck cyst with a lymph node that showed signs of an acute inflammation near the cyst. These findings support the theory that a preexisting lateral neck cyst may be “activated” by an intraoral inflammation. The different theories of the origin of lateral neck cysts are presented and discussed in the context of the case description.

Progress in neuropathology of the neuronal ceroid lipofuscinoses.

1999

Abstract Since the last, 6th, International Congress on Neuronal Ceroid-Lipofuscinoses, neuropathological advances in neuronal ceroid lipofuscinoses (NCL) have been made in several areas: (1) In adult NCL (ANCL) lipopigments have now been repeatedly confirmed to contain subunit c of mitochondrial ATP synthase and even sphingolipid activators (saposins). ANCL lipopigments have also been confirmed in extracerebral tissues including skin, skeletal muscle, and spleen, but not yet lymphocytes (2). Among circulating blood cells not only B cells and subclasses of T lymphocytes, i.e., CD4 + , CD8 + , and CD56 cells, but also monocytes have been found to contain NCL lipopigments, indicating that thi…

Neuronal ceroid-lipofuscinosis--late-infantile or Jansky-Bielschowsky type--revisited.

1996

Among the now eight genetic types of neuronal ceroid-lipofuscinoses (NCL), CLN1 to CLN8, CLN2 is considered classic late-infantile NCL. It was originally described by Janský in a family of eight children with four of them affected [Janský J (1908) Sborn Lek 13:165-196] and, subsequently, by Bielschowsky in a family of three children each of whom was affected, and, hence, termed Janský-Bielschowsky type of NCL. Earlier, archival studies of Bielschowsky's original post-mortem tissue blocks had documented accumulation of autofluorescent lipopigments with a curvilinear ultrastructure. In a subsequent study, described here, immunohistochemical absence of the CLN2-related lysosomal enzyme tripept…

Electron microscopic studies on skin and lymphocytes in early juvenile neuronal ceroid-lipofuscinosis.

1987

Skin and lymphocytes of three patients with early juvenile neuronal ceroid-lipofuscinosis (NCL) were ultras trueturally investigated. Fingerprint profiles (FPP), isolated and I or mixed with curvilinear profiles (CLP), in various dermal cells and large, usually single lipopigments delineated by a trilaminar membrane and filled with a granular matrix, FPP and occasionally lipid droplets in lymphocytes were observed in all three patients. Characteristic lipopigments in lymphocytes are an important feature to differentiate between early juvenile NCL and late infantile and juvenile NCL.

Prevalence of oral mucosal lesions in psoriatic patients: A controlled study

2012

Objectives: This study aimed to investigate and compare the prevalence of oral mucosal lesions in a group of psoriatic patients and healthy subjects, and its correlation to multiple clinical parameters. Study design: 100 psoriatic patients and 100 closely matched controls underwent clinical oral examination. Oral lesions were diagnosed according to the criteria proposed by the World Health Organization (WHO). The patients filled the Hospital Anxiety and Depression (HAD) questionnaire and the Dermatology Life Quality Index (DLQI). The severity of psoriasis was assessed by the Psoriasis Area and Severity Index (PASI). Categorical variables were evaluated using Chi-square test or Fisher’s exac…

An ultrastructural study on retinal neural and pigment epithelial cells in ovine neuronal ceroid-lipofuscinosis.

1990

Ovine neuronal ceroid-lipofuscinosis represents another well studied model for human neuronal ceroid-lipofuscinosis (NCL). Accumulation of abnormal lipopigments in various retinal neurons, and loss of photoreceptors are similar to the lesions in human juvenile NCL and indicate that the sheep is a suitable model in which to study the pathogenesis of both NCL lipopigment formation and retinopathia pigmentosa. However, this latter process is not as advanced in NCL-diseased sheep as in human patients but far more obvious than in canine NCL in which retinopathy cannot be unequivocally documented. Ovine NCL shares with canine NCL peculiar lamellar inclusions in retinal pigment epithelial cells wh…

Objective: Severe malnutrition in patients with anorexia nervosa (AN) as well as possible trait-related aberrations lead to pronounced structural brain changes whose reversibility after recovery is currently unclear. Previous diffusion tensor imaging (DTI) studies investigating white matter (WM) microstructure alterations in AN are inconsistent. Methods: In this so far largest DTI study in adults, we investigated 33 AN patients, 20 recovered (REC), and 33 healthy women. DTI data were processed using the "DTI and Fiber tools," and the Computational Anatomy Toolbox. WM integrity, both in terms of fractional anisotropy (FA) and mean diffusivity (MD), was assessed. Results: We found a significa…

Effects of normobaric oxygen on ciliary beat frequency of human respiratory epithelium

1998

Respiratory infection is a major cause of morbidity after general anaesthesia. Impairment of respiratory ciliary beat frequency (CBF) by different stress factors causes a decrease in mucus transport rate (MTR). We have tested the effect of different concentrations of oxygen on CBF of human respiratory epithelium in a prospective, randomized, in vitro study. Samples of superficial mucosa of the inferior nasal turbinates of 20 non-smoking healthy volunteers were harvested and exposed to three different oxygen environments (group I = 21% oxygen, group II = 60% oxygen and group III = 95% oxygen) for 2 h. In 50% of the samples, exposure time was prolonged. At 30, 60, 90, 120 and 240 min, light m…
