ABSTRACT: The routine newborn assessment should include an examination for size, macrocephaly or microcephaly, changes in skin color, signs of birth trauma, malformations, evidence of respiratory distress, level of arousal, posture, tone, presence of spontaneous movements, and symmetry of movements. A newborn with one anatomic malformation should be evaluated for associated anomalies. Total and direct bilirubin levels should be measured in newborns with jaundice, and a complete blood count should be obtained in those with pallor or a ruddy complexion. Neurosurgical consultation is necessary in infants with craniosynostosis accompanied by restricted brain growth or hydrocephalus, cephaloceles, or exophytic scalp nodules. Neck masses can be identified by their location and include vascular malformations, abnormal lymphatic tissue, teratomas, and dermoid cysts. Most facial nerve palsies resolve spontaneously. Conjunctivitis is relatively common in newborns. Infants with chest abnormalities may need to be evaluated for Poland's syndrome or Turner's syndrome. Murmurs in the immediate newborn period are usually innocent and represent a transition from fetal to neonatal circulation. Because cyanosis is primarily secondary to respiratory or cardiac causes, affected newborns should be evaluated expeditiously, with the involvement of a cardiologist or neonatologist.
ABSTRACT: Basal cell nevus syndrome is an autosomal dominant condition with complete penetrance and variable expressivity. It is characterized by five major components, including multiple nevoid basal cell carcinomas, jaw cysts, congenital skeletal abnormalities, ectopic calcifications, and plantar or palmar pits. Other features include a host of benign tumors, ocular defects, and cleft lip and palate. Guidelines for diagnosis include a family history, careful oral and skin examinations, chest and skull radiographs, panoramic radiographs of the jaw, magnetic resonance imaging of the brain, and pelvic ultrasonography in women.
ABSTRACT: The interrupted vertical and horizontal mattress suture techniques are two of the most commonly used skin closure methods. These mattress sutures promote wound edge eversion and less prominent scarring. Vertical and horizontal mattress sutures allow for skin edges to be closed under tension when wound edges have to be brought together over a distance. The corner stitch, a variation of the horizontal mattress suture, is commonly used for closure of angled skin flaps or wounds. Although mattress sutures can produce surface scarring or "railroad marks," early removal of these sutures can limit this damage.
Common Skin Conditions During Pregnancy - Article
ABSTRACT: Common skin conditions during pregnancy generally can be separated into three categories: hormone-related, preexisting, and pregnancy-specific. Normal hormone changes during pregnancy may cause benign skin conditions including striae gravidarum (stretch marks); hyperpigmentation (e.g., melasma); and hair, nail, and vascular changes. Preexisting skin conditions (e.g., atopic dermatitis, psoriasis, fungal infections, cutaneous tumors) may change during pregnancy. Pregnancy-specific skin conditions include pruritic urticarial papules and plaques of pregnancy, prurigo of pregnancy, intrahepatic cholestasis of pregnancy, pemphigoid gestationis, impetigo herpetiformis, and pruritic folliculitis of pregnancy. Pruritic urticarial papules and plaques of pregnancy are the most common of these disorders. Most skin conditions resolve postpartum and only require symptomatic treatment. However, there are specific treatments for some conditions (e.g., melasma, intrahepatic cholestasis of pregnancy, impetigo herpetiformis, pruritic folliculitis of pregnancy). Antepartum surveillance is recommended for patients with intrahepatic cholestasis of pregnancy, impetigo herpetiformis, and pemphigoid gestationis.
Management of Foreign Bodies in the Skin - Article
ABSTRACT: Although puncture wounds are common, retained foreign bodies are not. Wounds with a foreign body sensation should be evaluated. The presence of wood or vegetative material, graphite or other pigmenting materials, and pain is an indication for foreign body removal. Radiography may be used to locate foreign bodies for removal, and ultrasonography can be helpful for localizing radiolucent foreign bodies. It is wise to set a time limit for exploration and to have a plan for further evaluation or referral. Injuries at high risk of infection include organic foreign bodies or dirty wounds. These should be treated with plain water irrigation and complete removal of retained fragments. In most cases, antibiotic prophylaxis is not indicated. If a patient presents with an infected wound, the possibility of a retained foreign body should be considered. Tetanus prophylaxis is necessary if there is no knowledge or documentation of tetanus immunization within 10 years, including tetanus immune globulin for the person with a dirty wound whose history of tetanus toxoid doses is unknown or incomplete.
Punch Biopsy of the Skin - Article
ABSTRACT: Skin biopsy is one of the most important diagnostic tests for skin disorders. Punch biopsy is considered the primary technique for obtaining diagnostic full-thickness skin specimens. It requires basic general surgical and suture-tying skills and is easy to learn. The technique involves the use of a circular blade that is rotated down through the epidermis and dermis, and into the subcutaneous fat, yielding a 3- to 4-mm cylindrical core of tissue sample. Stretching the skin perpendicular to the lines of least skin tension before incision results in an elliptical-shaped wound, allowing for easier closure by a single suture. Once the specimen is obtained, caution must be used in handling it to avoid crush artifact. Punch biopsies are useful in the work-up of cutaneous neoplasms, pigmented lesions, inflammatory lesions and chronic skin disorders. Properly administered local anesthesia usually makes this a painless procedure.
Seborrheic Dermatitis: An Overview - Article
ABSTRACT: Seborrheic dermatitis affects the scalp, central face, and anterior chest. In adolescents and adults, it often presents as scalp scaling (dandruff). Seborrheic dermatitis also may cause mild to marked erythema of the nasolabial fold, often with scaling. Stress can cause flare-ups. The scales are greasy, not dry, as commonly thought. An uncommon generalized form in infants may be linked to immunodeficiencies. Topical therapy primarily consists of antifungal agents and low-potency steroids. New topical calcineurin inhibitors (immunomodulators) sometimes are administered.
Essentials of Skin Laceration Repair - Article
ABSTRACT: Skin laceration repair is an important skill in family medicine. Sutures, tissue adhesives, staples, and skin-closure tapes are options in the outpatient setting. Physicians should be familiar with various suturing techniques, including simple, running, and half-buried mattress (corner) sutures. Although suturing is the preferred method for laceration repair, tissue adhesives are similar in patient satisfaction, infection rates, and scarring risk in low skin-tension areas and may be more cost-effective. The tissue adhesive hair apposition technique also is effective in repairing scalp lacerations. The sting of local anesthesia injections can be lessened by using smaller gauge needles, administering the injection slowly, and warming or buffering the solution. Studies have shown that tap water is safe to use for irrigation, that white petrolatum ointment is as effective as antibiotic ointment in postprocedure care, and that wetting the wound as early as 12 hours after repair does not increase the risk of infection. Patient education and appropriate procedural coding are important after the repair.
