Clinical and pathological findings in reexcision of incompletely excised basal cell carcinomas.

In common practice, patients with incompletely excised basal cell carcinomas (BCCs) are referred to elective reexcision. In previous reports, it was observed that tumor cells are found in only 50% of the reexcised specimens. The authors performed a retrospective analysis of a large series of patients to evaluate clinical and pathological findings in patients who underwent reexcision of incompletely excised BCCs. A total of 1,478 BCCs arising in 1,278 patients were excised by plastic surgeons in a plastic and reconstructive surgery department during a 4-year period. In 159 patients (10.8%), the excision was incomplete according to the pathological report. These tumors were defined as an incompletely excised BCCs. One hundred of the 159 patients with incompletely excised BCCs (62.9%) were reoperated. Residual tumor cells were found in 28 of 100 patients (28%) within the pathological specimen of the reexcised tissue (defined as positive reexcision, or +veRE). There was no correlation between +veRE and the age or sex of the patient. Location of the BCCs in the cheeks, eyelids, or ears was associated with a low percent of +veRE (10.0%, 13.3%, and 22.2% respectively). Pathological factors associated with a low percent of +veRE were dermal inflammatory infiltrate in the pathological specimen (p = 0.003) and sun damage pathological changes (p = 0.03), but there was no correlation with the pathological subtype distribution of the tumors. The authors conclude that lack of tumor cells at reexcision of incompletely excised BCCs is associated with location of the tumors in the cheeks, eyelids, and ears, and with pathological findings of dermal inflammatory infiltrates or sun damage changes. The roles of inflammatory and solar changes in the destruction of residual carcinoma cells should be investigated further.

An improved design for vacuum tube drains.

Mini vacuum drains can be helpful in reconstructive surgery. The drains may be assembled using a scalp needle and a vacuum tube. The addition of the adapter that is used with the vacuum tubes for blood sampling improves the ease of use and practicality of these drains and increases their safety.

A graded work site intervention program to improve sun protection and skin cancer awareness in outdoor workers in Israel.

OBJECTIVES: A graded worksite intervention program to improve sun protection and skin cancer awareness of outdoor workers was implemented and evaluated longitudinally over a period of 20 months. METHODS: Outdoor male workers (144/213 recruits) from geographically separated units of the Israel National Water Company were allocated to complete (n = 37), partial (n = 72) or minimal (n = 35) intervention groups. Subsequent to the assignment and training of local safety officers, an educational and medical screening package was provided to the corresponding groups either once, or repeatedly a year later. Personal sun protective gear was provided upon repeated intervention. Outcome measures were evaluated through self-response questionnaires administered prior to the first intervention pulse, and 8 months after the first and second interventions. RESULTS: A 15-61% improvement in sun-protection habits was noted in the entire study population 8 months after initialization, compared to no sunscreen use, 20% sun-exposed skin area and highest mean occupational exposure dose of 1.68 MED/day at pre-test. An even greater use of sunscreen was evident 1 year later in the complete and partial intervention groups, + 80% and + 52%, respectively. The baseline rate of self-examination of the skin in the same two groups (49%) increased significantly at post-test (+ 71% and + 53%, respectively). CONCLUSIONS: This integrated intervention program led to significantly improved sun protection and skin cancer awareness. Repeated intervention combined with the supply of sun-protective gear contributed to an even greater impact.

Subungual amelanotic melanoma.

We describe a 76-year-old white male with subungual amelanotic melanoma. The lack of pigmentation of the lesion may cause misdiagnosis and aggravate its poor prognosis.

A thermal burn to a prolapsed uterus.

Burns to the concealed area of the perineum, are relatively rare and usually associated with massive burns and a high mortality rate. A rare case of a thermal burn to a prolapsed uterus is described. The victim was a 72-year-old Bedouin woman, with a 70 per cent total body surface area deep burn from an open fire. In addition to the conventional treatment dictated by such a burn, two unique problems must be considered: (1) the common pathogens of the uterus, Neisseria gonorrhoeae, Chlamydia trachomatis and mycoplasma, are different from those of the skin; (2) the lymphatics of the uterus drain directly into the abdominal cavity and the risk of peritonitis and generalized infection is potentially higher. Intravenous, prophylactic, broad-spectrum antibiotics were therefore initiated immediately following admission. These included: cefoxitin, gentamicin and metronidazole a combination that covers both the potential pathogens of the uterus and the common pathogens of the skin. In addition, and for the same reason, Betadine substituted Flamazine for the local treatment of the exposed uterus. Our patient did not survive the burn, but in a similar, unusual case, the local and systematic remedies must protect against uterine pathogens that are not commonly seen in a burn victim.
