Fusiform excision.

The fusiform excision technique is commonly used by physicians for removing skin and subcutaneous lesions. The technique requires basic skills in anesthetic administration, lesion excision, and suture closure. Physicians experienced in skin surgery can often perform the procedure unsupervised after two to five precepted sessions. The fusiform excision technique should be used to biopsy any suspicious pigmented lesions because prognosis may depend on the depth of the lesion. A properly designed fusiform excision has a length-to-width ratio of 3 to 1 and produces a 30-degree angulation at both edges of the wound. The skin edges should be everted during the closure to improve final scar appearance. Malignant growths may require a second procedure to provide a wider margin of excision around the lesion. Post-excisional wound infections are uncommon with use of proper aseptic technique.

The infrared coagulator in dermatology.

The infrared coagulator was developed 10 years ago in West Germany. It shares some properties with an infrared laser but differs by virtue of its noncoherent, multispectral light source. It has evolved to become a cheap, portable instrument with a wide spectrum of applications in medicine, including dermatology. The treatment of tattoos and vascular lesions with the infrared coagulator is discussed, along with the technical considerations and limitations associated with this instrument.

The challenge of biophysics to dynamic dermatology.

Dermatologic biophysics has much to offer both clinical and investigative dermatology. For the clinician, the radiation biophysicist can provide accurate measurements of ionizing and nonionizing outputs, including those for PUVA, and critical evaluation of radiation safety measures. In optics, there is a need for accurate measurements of skin color and examination of the skin at moderate magnification. The biophysicist, with the biomedical engineer, can improve all the physical modality instrumentation used in practice. In investigative dermatology, there is the cellular biophysics of radiation. Doppler techniques for skin circulation, spectroscopy of living cells, and many other applications are suggested for current and future studies.

Dermatologic surgery and human immunodeficiency virus disease.

In summary, the statistically greater risk of disease among health care workers who suffer occupational needle sticks or similar exposure to contaminated blood remains hepatitis. Routine vaccination of health care workers who are at risk for exposure to hepatitis B, combined with common-sense implementation of risk management behaviors should reduce the chances of occupationally acquired blood-borne disease to levels of acceptable risk. The practice of medicine has never been without risk to the health care worker who is engaged in direct patient care, and the present epidemic is no exception. Collective action to minimize the impact of HIV disease continues to be the prudent and compassionate course of action.

Use of cotton-tipped applicators during skin examination and dermatologic surgery.

The cotton-tipped applicator is a widely available and versatile tool for the dermatologist. In addition to the common uses of this inexpensive tool there are many other ways for the dermatologist to use cotton-tipped applicators. From its usefulness in dermatologic examination and potassium hydroxide preparations to its multiple surgical applications, the cotton-tipped applicator is a valuable and underrated tool.

Local anesthesia by jet-injection device in minor dermatologic surgery.

BACKGROUND: Pain and needle-phobia can be a problem during the application of local anesthesia with syringe and needle. OBJECTIVE: To evaluate a jet-injection device (without needle) to deliver local anesthesia. METHODS: Two hundred and six minor dermatological procedures using a jet-injection device for administering local anesthesia into skin tissue were performed. We comment on the technical procedures, application, usefulness in relation to areas involved and the anatomical location of lesion, and total dosage of the anesthetic agent. RESULTS: Total absence of pain during installation of anesthetic (N = 194; 94%). Good level of anesthesia in all patients. No local adverse effects. CONCLUSION: The jet-injection device is easy to handle, it is harmless, it provides good levels of anesthesia, and the dosage of anesthetic agent is smaller than the dosage administered with conventional methods.

On history-taking before surgery.

History-taking is discussed with particular reference to cutaneous surgery. Systematic questioning with regard to general health, established and potential allergies, medicaments currently being taken, and miscellaneous relevant matters is important to the planning, execution, and outcome of surgical procedures.

Computer-guided microsurgery: surgical evaluation of a telerobotic arm.

A new telerobotic arm was evaluated in different microsurgical procedures. The system consisted of a robotic arm bearing a microsurgical forceps controlled by a joystick-like master unit operated by the surgeon's hand. The robotic arm functioned as an operating as well as assisting instrument. Advantages of the system were its precise functioning, which was especially important when tissue or instruments had to be held for a longer period of time, as well as its ability to replace an assisting person to some extent. Deficiencies of the system were its 10-min startup, the spatial conflict with in the operative field, and the poor rotation of the robotic tip. In some procedures, the telerobotic arm could replace the standard microsurgical instrument guided by the surgeon's second hand; in other maneuvers it could function as the surgeon's third hand with precision and void of tremor.
