Regarding Headlice T/F
Nits can survive 30 days away from the host
False
Nits can survive and hatch after 10 days away from the host (Bolognia)
Nits are the eggs of headlice
T/F Regarding Headlice
Hatched eggs are tan brown
False - hatched eggs are clear to white
Bolognia:
Viable eggs are usually tan to brown in color, whereas hatched eggs are clear to white
Regarding Headlice T/F
All topical treatments are done twice, a week apart.
True
Bolognia:
With all topical preparations (regardless of package instructions), two applications, 1 week apart,
are advisable in order to: (1) kill any nits that survived treatment; (2) better defend against the growing resistance to many pediculicides; and
(3) reduce the risk of reinfestation by means of fomites.
Regarding Headlice T/F
Petroleum jelly is lethal
False
Bolognia
Unsubstantiated claims of successful treatment with alternative, non-pesticidal products, including petroleum jelly, hair pomade, olive oil, mayonnaise, vegetable oil and mineral oil, persist. Such products may slow the movements of adult lice and allow them to be more easily combed out
of the scalp, but these substances are not lethal to lice.
Regarding Headlice T/F
Eggs are on the hair close to the scalp
True
Bologina: Oval egg capsules (nits) measure 0.8 mm in length and are usually laid close to the scalp for warmth; in general, eggs located within 1 cm of the scalp are unhatched. In warm climates, however, viable nits may
be found 15 cm or more from the scalp, especially in the area above the nape of the neck
Re: Acanthosis palmaris (Tripe palms) T/F
Associated with malignancy in >50%
True (about 90%)
Rook
Acanthosis palmaris describes thickened skin of the palms and occasionally the soles with an enhanced dermatoglyphic change, causing a velvety or less commonly a pitted, honey combed pattern of the hand. It is associated with neoplasia in about 90% of cases and maybe the only paraneoplastic manifestation in 30–40%. It may also occur with one or both of malignant acanthosis nigricans or the sign of Leser–Trélat, or with florid cutaneous papillomatosis
Re: Acanthosis palmaris (Tripe palms) T/F
More common in men
True
Rook: It occurs particularly in men, especially when the underlying tumour is a lung cancer
Re: Acanthosis palmaris (Tripe palms) T/F
Most common malignancy is bronchial carcinoma
True
Rook
Most commonly, the underlying tumour is bronchial or gastric, together accounting for over 50% of the associated malignancies. Many other sites are reported includ-
ing tumours of the genito-urinary tract, as well as carcinomas in the breast and other organs.
Acanthosis palmaris occurring alone is more often associated with bronchial carcinoma compared with combined acanthosis nigricans and acanthosis palmaris, in
which gastric carcinoma is more common. If nail clubbing is also present (especially in a male patient), then bronchial carcinoma is very likely.
Interestingly, the appearance or exacerbation of tripe
palms in a known cancer patient may be a sign of recurrence of the malignancy
Re: Acanthosis palmaris (Tripe palms) T/F
It tends to resolve spontaneously with treatment of underlying malignancy
? (not specifically outlined in Rook or Bologina:
Bolognia for AN (not tripe palms): Treatment of the underlying malignancy, or effective treatment of the endocrinopathy, including weight loss and use of insulin sensitizers, may result in improvement or disappearance of the acanthosis
nigricans. Recurrence of malignancy-associated acanthosis nigricans requires a search for recurrent cancer.
Dermnet
Approximately 3 out of 10 cases of tripe palms resolve when the underlying cancer is managed. However, tripe palms may persist despite remission of the underlying cancer.
Re: Acanthosis palmaris (Tripe palms) T/F
It is associated with acanthosis nigricans
True
Rook.
Acanthosis palmaris occurring alone is more often associated with bronchial carcinoma compared with combined acanthosis nigricans and acanthosis palmaris, in
which gastric carcinoma is more common.
