Tyrosine kinase inhibitors (TKIs) against the epidermal growth factor receptor (EGFR) are the standard of care treatment in non-small cell lung cancer (NSCLC). TKIs are used first line in EGFR mutation-positive NSCLC; erlotinib is the only TKI approved for subsequent lines of treatment in EGFR wild-type NSCLC. As promising as TKIs are in helping patients avoid some of the side effects of tradit...

Some literature suggests that an EGFR inhibition-induced rash can be used as a clinical marker, but few studies report the correlation between a spectrum of cutaneous toxicities from EGFR inhibition and drug efficacy. We report about a woman with a stage IV lung adenocarcinoma using erlotinib monotherapy, who experienced a spectrum of cutaneous toxicities, including papulopustular rash, mucosit...

Onychomadesis is a reversible, painless, noninflammatory condition in which there is proximal shedding of the nail plate from the nail matrix. It can occur in fingernails, toenails or both. It may be secondary to systemic disorders, high fevers, bullous dermatoses, Kawasaki disease, infections (streptococcal infections and measles), zinc deficiency, local trauma, acute paronychia, and drug reac...

Epidermal growth factor inhibitors (EGFRI), the first targeted cancer therapy, are currently an essential treatment for many advance-stage epithelial cancers. These agents have the superior ability to target cancers cells and better safety profile compared to conventional chemotherapies. However, cutaneous adverse events are common due to the interference of epidermal growth factor receptor (EG...

Primary prevention is the mainstay of management of occupational dermatoses. Despite the high rates of dermatoses found in a study of 686 female workers in a canning factory in March 1990, use of protective gloves was extremely low, even though there was evidence that they prevented acute paronychia and intertrigo. Reasons associated with low glove use were unavailability, discomfort and worker...

Green nail syndrome (chromonychia) is a nail disorder characterized by onycholysis and green-black discoloration of the nail bed. This condition is often associated with chronic paronychia. Pseudomonas aeruginosa is the most commonly identified organism in cultures from the affected area. Despite the various treatment options available, removal of the nail is still necessary in many cases. A 35...

BACKGROUND The introduction of HIV-1 protease inhibitors into the treatment of patients infected with HIV-1 has had a major influence on clinical practice. However, the use of protease inhibitors is frequently associated with the development of resistance and several side effects and interactions with other drugs have been reported. OBSERVATIONS We present the first pediatric patient with par...

To date, there are no phase III trial data that can guide healthcare professionals in managing toxicities of epidermal growth factor receptor inhibitors (EGFRIs). This exploratory survey assessed the similarities and differences in nursing management of EGFRI-related toxicities across 10 European countries. A questionnaire that was sent to ten nurses who specialize in the treatment of patients ...

We studied the root distribution and the effects of leachates from the dominant shrub in rosemary scrub, Florida rosemary (Ceratiola ericoides), on germination of seven subordinate rosemary scrub species. For rosemary scrub specialists, (Eryngium cuneifolium and Hypericum cumulicola), germination was suppressed by the leaf and litter leachates. For species that are not found exclusively in rose...

Acrometastasis is a rare occurrence, especially when affecting the hands. It represents around 0.007-0.2% of all metastatic lesions. The most common site of origin is the lung, accounting for 40-50% of all cases reported in the literature. Kidneys and breasts are other sites also associated with neoplastic lesions that disseminate to the hands. More rarely, the site of origin may be the gastroi...
