1. Syringocystadenoma papilliferum combined with a tubular apocrine adenoma
Abstract: Syringocystadenoma papilliferum and tubular apocrine adenoma are rare benign sweat gland tumors. Syringocystadenoma papilliferum occurs alone or in association with other tumors. Although it is rare, the association of tubular apocrine adenoma with syringocystadenoma papilliferum developing in a sebaceous nevus on the scalp is well documented. Howe

2. Ductal eccrine carcinoma of the axilla: a diagnostic pitfall
Abstract: Ductal eccrine carcinoma (DEC) is a rare sweat gland carcinoma with ductular differentiation. Clinically, it is characterized by a slowly growing, hardened plaque or nodule predominantly located on the head and neck. Histologically, DEC shares similar features to invasive breast carcinoma, thus causing great diagnostic challenges. We report a 69-ye

3. Eccrine poroma and porocarcinoma on the same unusual location: report on two cases
AbstractEccrine poroma is a benign adnexal tumour of the uppermost portion of the intraepidermal eccrine sweat gland duct and acrosyringium. Eccrine porocarcinoma is the malignant phenotype arising from the intraepidermal portion of the eccrine sweat gland duct epithelium or from pre-existing eccrine poroma. Both commonly occur in the palms or sides of the f

4. Late-onset of eruptive syringomas: a diagnostic challenge
AbstractSyringoma is a benign, adnexal tumor of the eccrine sweat gland ducts. Eruptive syringomas are a rare variant, occurring before or during puberty in most cases. A 57-year-old man was observed in our department, with a 10-year history of multiple brownish papules (1-4mm in diameter), localized on the neck, shoulders, trunk and axillae. The clinical di

5. Desempenho e termorregulação de corredores jovens e de meia-idade com VO2 máx similar em corridas de intensidades fixa e autorregulada em ambientes quente e termoneutro
In order to compare the heat exercise performance between middle-aged and young runners with similar VO2peak using self-paced and fixed workload intensity, 26 endurance runners; seven men (MA_M: 54 ± 2 years; 58 ± 4 ml.kg-1.min-1) and six middle-aged women (MA_W: 54 ± 4 years; 48 ± 3 ml.kg-1.min-1); seven men (YO_M: 28 ± 1 years; 61 ± 5 ml.kg-1.min-1)

6. Respostas de sudorese de nadadores, corredores e indivíduos não treinados após exercício no calor
A concentração de eletrólitos no suor e a taxa de sudorese estão bem descritas em atletas que treinam na terra e em não atletas. Embora exista alguma pesquisa acerca das respostas termorregulatórias de nadadores, não foi encontrada alguma que tenha verificado a concentração eletrolítica no suor. O objetivo deste estudo foi comparar a taxa de sudore

7. Requirement for Shh and Fox family genes at different stages in sweat gland development
Sweat glands play a fundamental role in thermal regulation in man, but the molecular mechanism of their development remains unknown. To initiate analyses, we compared the model of Eda mutant Tabby mice, in which sweat glands were not formed, with wild-type (WT) mice. We inferred developmental stages and critical genes based on observations at seven time poin

8. IMPEDANCE CHANGES ACROSS THE FOOTPAD OF THE CAT IN RELATION TO ACTION AND SECRETION IN SWEAT GLANDS*
Impedance changes across the footpad of the cat occur as the result of sweat gland activity after stimulation of the sudomotor nerves. It is possible to discern two phases of impedance change; one, early, associated with the action potential of sweat gland cells; the other, later, being the well-known change associated with secretion and reabsorption.1 After

9. Surgical resection for pulmonary metastases of sweat gland carcinoma.
A case of axillary sweat gland carcinoma which metastasised to both lungs six years after resection of the primary lesion is described. The lesions were resected and three years later two further pulmonary metastases were resected.

10. Defective beta adrenergic response of cystic fibrosis sweat glands in vivo and in vitro.
Abnormal ductal NaCl absorption has been known as the only defect in cystic fibrosis (CF) sweat glands. We have fortuitously found that the secretory portion of CF sweat glands is also abnormal in that it failed to show a sweating response to beta adrenergic stimulation (isoproterenol, [ISO]) both in vivo and in vitro. For the in vitro sweat test, eccrine sw

11. Eccrine spiradenoma of eyelid: case report.
A case report is presented of eccrine spiradenoma, a benign sweat gland tumour which, though not uncommon generally, is rare in the eyelid. The possibility of sweat gland tumour should be kept in mind in the diagnosis of eyelid tumours.

12. Micropuncture studies of the sweat formation in cystic fibrosis patients
In order to determine whether the precursor solution of sweat is abnormal in cystic fibrosis, osmolality and concentrations of sodium and chloride were measured in fluid obtained by micropuncture from the sweat gland coil of the nail fold of patients with this disease. Osmolality was 323±4.8 SE (mOsm/kg of water), sodium concentration was 151±1.1 SE (mEq/l
