Molecular alterations in lesions of anogenital mammary-like glands and their mammary counterparts including hidradenoma papilliferum, intraductal pap…
2017
Lesions affecting anogenital mammary-like glands (AGMLG) are histopathologically very similar to those seen in the breast but whether this morphological similarity is also reflected at the genetic level is unknown. To compare the underlying molecular mechanisms in lesions of AGMLG and their mammary counterparts, we analyzed the mutational profile of 16 anogenital neoplasms including 5 hidradenomas papilliferum (HP), 1 lesion with features of HP and fibroadenoma (FA), 7 FA, 3 phyllodes tumors (PhT)) and 18 analogous breast lesions (6 intraductal papillomas (IDP), 9 FA, and 3 PhT) by high-coverage next generation sequencing (NGS) using a panel comprising 50 cancer-related genes. Additionally,…
Water content of latent fingerprints - Dispelling the myth.
2016
Abstract Changing procedures in the handling of rare and precious documents in museums and elsewhere, based on assumptions about constituents of latent fingerprints, have led the author to an examination of available data. These changes appear to have been triggered by one paper using general biological data regarding eccrine sweat production to infer that deposited fingerprints are mostly water. Searching the fingerprint literature has revealed a number of reference works similarly quoting figures for average water content of deposited fingerprints of 98% or more. Whilst accurate estimation is difficult there is no evidence that the residue on fingers could be anything like 98% water, even…
Epithelial markers and differentiation in adnexal neoplasms of the skin: an immunohistochemical study including individual cytokeratins
1995
Applying immunohistochemical procedures for the detection of eight different cytokeratin (CK) polypeptides and other differentiation markers, we compared the staining patterns of normal cutaneous structures with those of benign adnexal tumors (n = 65). Syringomas exhibited a marker pattern highly reminiscent of that seen in normal dermal eccrine ducts (EMA in peripheral cells, CK 10 in intermediate cells, and CK 6, CK 19, and CEA in luminal cells). Nodular hidradenomas exhibited complex patterns suggesting relationship between tumor cells, including clear cells, and normal secretory coil cells (CK 7, CK 8, CK 19, and EMA); however, dermal-duct and epidermoid differentiation were also detect…
Multiple nevoid spiradenomas.
1994
This report delineates a new clinical presentation of multiple benign spiradenoma (BS), a diffuse linear nevoid pattern. A 16-year-old girl, in otherwise good health, had many papulonodular lesions, varying in color from blue-gray to bright red, disposed linearly on the right half of her body, involving the periorbital region, cheek, lateral side of the neck, trunk, linea alba, right thigh, and leg. Only a few nodules were slightly painful. Lesions were reported to be present at birth; no family members had similar lesions, either in solitary or multiple form. Excisional biopsies of three lesions from the neck, abdomen, and leg, respectively, were performed; histologically, all three sample…
Comparative cytokeratin analysis of sweat gland ducts and eccrine poromas.
1991
Human eccrine sweat gland ducts and benign and malignant eccrine poromas were studied for the expression of various cytokeratins (CK) and vimentin by applying immunoperoxidase and immunofluorescence microscopy to frozen or paraffin-embedded sections, and using two-dimensional gel electrophoresis and immunoblotting. In acrosyringia and dermal eccrine ducts, the luminal cells exhibited intense staining for CKs 1/10/11 and 19. The periluminal cell layers of acrosyringia contained CKs 1/10/11, while CK 5 was absent. In contrast, the basal cell layer of dermal ducts was only positive with the antibody against CK 5, i. e. a pattern resembling that seen in epidermal basal cells. CK 9 was detected …
Significance of lipopigments with fingerprint profiles in eccrine sweat gland epithelial cells.
1995
Lipopigments with fingerprint profiles in eccrine sweat gland epithelial cells are regular findings in childhood NCL. They have also been described in adult NCL (ANCL) a few times, but not consistently. However, they have been considered nonspecific when not matched by similar abnormal profiles in noneccrine sweat gland epithelial cells. These conflicting reports may pose a diagnostic dilemma as outlined in the following 2 examples. Patient 1 is a 20-year-old man who developed severe tetraparesis and dementia over 2 years. Electroencephalogram was abnormal with epileptiform discharges. The patient died at age 21 years without autopsy ; no other relatives are known to have a similar disease.…
Ultrastructural Pathology of Eccrine Sweat Gland Epithelial Cells in Globoid Cell Leukodystrophy
1993
Three of four children were recognized by deficient β-galactocerebrosidase activities as having globoid cell leukodystrophy inclusions in sweat gland epithelial cells, similar in ultrastructure to those seen in Schwann cells. This observation in globoid cell leukodystrophy emphasizes the need to include sweat gland epithelial cells in examinations of skin in globoid cell leukodystrophy, as well as in any neurometabolic disorder. ( J Child Neurol 1993;8:171-174).
Infant developmental profile of Crisponi syndrome due to compound heterozygosity for CRLF1 deletion.
2020
Crisponi syndrome/CISS1, is an autosomal recessive ciliary neurotrophic factor receptor (CNTFR)-related genodermatosis caused in 95% of cases by mutations in CRLF1 on chromosome 19p13. The CNTFR pathway is important for CNS development. Crisponi syndrome/ CISS1 can be suspected in the presence of the following clinical triad: camptodactyly with fisted hands, intermittent hyperthermia and muscular contractions with feeding difficulties.
Orphan symptoms in advanced cancer patients followed at home
2013
Abstract Orphan symptoms are rarely assessed, particularly at home. The aim of this multicenter prospective study was to assess the prevalence of these symptoms and eventual factors possibly associated in advanced cancer patients at admission of a home care program. A prospective study was performed at three home care programs in Italy. Patients' data were collected, including age, sex, diagnosis, and Karnofsky status. Possible contributing factors were analyzed; preexisting neurological diseases, cerebral metastases, hyperthermia, diabetes, a state of dehydration clinically evident and/or oliguria, possible biochemical parameters when available, data regarding recent chemotherapy, opioids …
Detection of exercise adaptations by different specimens analysis
2015
This literature review is a compilation of the most used methods to monitoring athletes in training and competition. Blood is certainly the best known and proven methodology and a wide range of markers can be analyzed through it, but it can be difficult to obtain, especially among athletes or people who are afraid of needles. The use of saliva is an interesting alternative especially for the easy and less invasive method of collecting. The saliva infact contains a few of compounds diffused in the plasma, like water, electrolytes, proteins, metabolites and hormones. However, new methods yet poorly understood are slowly catching on; sweat for example, may carry far more information, may provi…
