In one study, milk samples from individual mammary quarters (n = 4,148) in seven spring-calving dairy herds in Ireland were collected on two occasions during lactation to measure somatic cell counts (SCCs). All quarters were scored (0 to 4) for teat-end hyperkeratosis to establish a correlation between this score and SCC. In a second study, a herd of 56 autumn-calving Holstein/Friesian dairy co...

MitEv, J. E., Zh. i. GErGovska and tch. M. MitEva, 2012. Effect of teat end hyperkeratosis on milk somatic cell counts in Bulgarian Black-and-White dairy cattle. Bulg. J. Agric. Sci., 18: 451-454 the aim of the study was to investigate the relationship between teat end hyperkeratosis score and somatic cell counts in milk in dairy cattle at different lactations. Five hundred Holstein cattle from...

OBJECTIVE Analyze whether the most frequent cases of non-dysplastic leukoplakias, hyperkeratosis (H), acanthosis (A), and hyperkeratosis with acanthosis (HA) have similar cell proliferation rates and to compare them with epithelial dysplastic (ED) leukoplakias and normal oral epithelium (NOE). STUDY DESIGN The sample comprised 10 cases of normal oral epithelium, 10 cases of hyperkeratosis, 10...

A 6-year-old child presented with generalized hyperkeratosis, most marked over the flexures; windswept deformity of the legs; and limping since 3 years. On the basis of the clinical, histopathologic and biochemical findings, he was diagnosed as a case of epidermolytic hyperkeratosis with rickets. He was treated with parenteral vitamin D3 and calcium supplements orally. Nutritional rickets has b...

A 20 year old boy presented to the dermatology department for treatment of a congenital icthyosis with a history of generalized erythroderma and trauma related blistering since birth. At the time of presentation he was noted to have red hyperkeratotic plaq corrugated over the joint flexures, elbows, knees after birth erythema and blistering improved but patient developed hyperkeratotic scaling ...

In this study, a possible new syndrome affecting 18 members of a family spanning 4 generations is described. The main features include palmoplantar hyperkeratosis, proportionate short stature, facial dysmorphism, clinodactyly, epilepsy, deafness, and hypodontia. This syndrome is inherited in an autosomal dominant manner with a high degree of penetrance but variable expressivity. This syndrome d...

The health and integrity of teats and streak canals is positively correlated to udder health and the incidence of mastitis. One sign of a reduction in teat end integrity is formation of excessive callus known as hyperkeratosis. Seiber and Farnsworth were the first to identify teat end hyperkeratosis and establish a teat end scoring system. Scoring systems have been developed to help standardize...

Scalp hyperkeratosis is common in childhood and adolescence. Diagnosis is affected by age, race, and history of infectious exposure, and associated symptoms including atopic features, alopecia, inflammatory nodules, presence and type of cutaneous lesions outside of the scalp, and nuchal lymphadenopathy. Tinea capitis is common in children with skin of color, especially black and Hispanic childr...

Epidermolytic hyperkeratosis is a form of ichthyosis normally resistant to topical treatments. Female patient monitored since 1978 diagnosed with epidermolytic hyperkeratosis. Clinical examination showed generalized hyperkeratosis and scaling. Given that no other treatments were available at the time, the patient was initially treated with keratolytic, systemic vitamin A and moisturizers, with ...
