Chronic myeloid leukemia-leukemia cutis mimicking a neutrophilic panniculitis-like leukemia cutis: Report of a rare case.

While drug-induced panniculitis is not uncommon in chronic myeloid leukemia (CML) patients on tyrosine kinase inhibitor therapy, it is rare for CML to initially present as a leukemic panniculitis. We present the case of a 45-year-old male with no relevant prior medical history presenting with 6 months of migratory nodules, 2 months of drenching night sweats, and a 20 pound weight loss. Physical examination showed firm subcutaneous nodules with overlying ecchymoses present on the right lateral thigh and left lower back.

Pediatric dermatology emergencies.

Many pediatric skin conditions can be safely monitored with minimal intervention, but certain skin conditions are emergent and require immediate attention and proper assessment of the neonate, infant, or child. We review the following pediatric dermatology emergencies so that clinicians can detect and accurately diagnose these conditions to avoid delayed treatment and considerable morbidity and mortality if missed: staphylococcal scalded skin syndrome (SSSS), impetigo, eczema herpeticum (EH), Langerhans cell histiocytosis (LCH), infantile hemangioma (IH), and IgA vasculitis.

Ten pearls every dermatologist should know about the appropriate use of relaxers.

Chemical relaxers are products marketed to straighten the hair and have been principally used by African Americans since the early twentieth century. They contain alkaline agents that break and reform hydrogen and disulfide bonds, leaving hair permanently straightened. Relaxers cause loss of tensile strength and increased fragility of the hair shaft that lead to increased risk of hair breakage and thinning.

The desmosomal protein desmoglein 1 aids recovery of epidermal differentiation after acute UV light exposure.

Epidermal structure is damaged by exposure to UV light, but the molecular mechanisms governing structural repair are largely unknown. UVB (290-320 nm wavelengths) exposure before induction of differentiation reduced expression of differentiation-associated proteins, including desmoglein 1 (Dsg1), desmocollin 1 (Dsc1), and keratins 1 and 10 (K1/K10), in a dose-dependent manner in normal human epidermal keratinocytes (NHEKs). The UVB-induced reduction in both Dsg1 transcript and protein was associated with reduced binding of the p63 transcription factor to previously unreported enhancer regulatory regions of the Dsg1 gene.

Determinants of access to antenatal care and birth outcomes in Kumasi, Ghana.

This study aimed to investigate factors that influence antenatal care utilization and their association with adverse pregnancy outcomes (defined as low birth weight, stillbirth, preterm delivery or small for gestational age) among pregnant women in Kumasi. A quantitative cross-sectional study was conducted of 643 women aged 19-48 years who presented for delivery at selected public hospitals and private traditional birth attendants from July-November 2011. Participants' information and factors influencing antenatal attendance were collected using a structured questionnaire and antenatal records.
