Facial rejuvenation: combining cosmeceuticals with cosmetic procedures.

Cosmetic patients are looking for a more youthful appearance without spending a lot of money, feeling any pain, or experiencing any postprocedure downtime. New cosmeceutical therapies can be used adjuvant to chemical peels, lasers, and injectables, making antiaging regimens less painful and requiring less postprocedural healing time. Adjunctive agents can be used to enhance chemical peels and decrease postinflammatory hyperpigmentation (PIH).

Metastatic laryngeal carcinoma mimicking eruptive keratoacanthomas: report of keratoacanthoma-like cutaneous metastases in a radiation port.

Metastatic skin lesions from a primary squamous cell carcinoma of the head and neck have only been reported in 1%-2% of these patients. Hence, skin metastases from laryngeal carcinoma are uncommon. Also, cutaneous metastases clinically presenting as a keratoacanthoma are rare.

Varicella zoster virus encephalitis in a patient with disseminated herpes zoster: report and review of the literature.

Herpes zoster infection occurs owing to reactivation of varicella zoster virus and classically manifests as a vesicular eruption involving a single dermatome. Disseminated herpes zoster - defined as having greater than twenty vesicles outside the primary or adjacent dermatome - is uncommon and typically occurs in immunocompromised individuals. Central nervous system complications during or following a zoster outbreak are exceedingly rare.

Evidence-based management of primary and localized Merkel cell carcinoma: a review.

Background: Merkel cell carcinoma is a rare and often lethal cutaneous neuroendocrine malignancy with a tendency for early and frequent locoregional and distant metastasis and relapses. It is a tumor of the elderly and immunosuppressed, which most often appears on sun-exposed areas of the body. There is growing interest in characterization of the disease and the best approach to its management.

Possible association between maternal lithium therapy and premature closure of the arterial duct. A case report.

Background: Frequent causes of premature ductal closure include spontaneous idiopathic closure in utero and maternal use of nonsteroidal anti-inflammatory drugs late in pregnancy.

Case: We describe a case of a preterm infant born to a mother treated with lithium throughout pregnancy who presented with right-sided cardiac enlargement at 18 weeks' gestation. Immediately following delivery, echocardiography demonstrated a small closing patent arterial duct.

Borrelia burgdorferi Infections in the United States.

It is becoming increasingly evident that the clinical presentation of infection with Borrelia burgdorferi varies greatly between different parts of the world. A growing number of European and Asian isolates of Lyme borreliae, differing from the American strain of Borrelia burgdorferi, have been identified in several different disorders. In light of the increasing number of reports describing an association between various cutaneous disorders and infection with Borrelia burgdorferi and the controversy that still remains over where Borrelia burgdorferi is truly pathogenic in these diseases, this review of the literature assesses the significance of these reports in substantiating these hypotheses, as such associations are important both diagnostically and therapeutically.

Posterior fossa syndrome after surgical removal of a pineal gland tumor.

Posterior fossa syndrome, characterized by oromotor or oculomotor apraxia, emotional lability, and mutism, occurs in some children after infratentorial tumor resection, and is thought to involve injury to the dentatothalamocortical tract. Previous cases of posterior fossa syndrome involved pediatric patients with cerebellar and other posterior fossa tumors. To heighten awareness that posterior fossa syndrome can occur after resections of tumors in other neuroanatomic locations, we present a 16-year-old boy who developed this syndrome after surgical removal of a supratentorial pinealoma, and we include a discussion of his self-reported signs.
