Considerable debate has taken place concerning cutaneous basosquamous carcinomas. Some authors believe they are merely a variant of basal cell carcinoma, based on the apparent rare occurrence of metastases. This comparative study of 33 cases of basosquamous, 1,796 cases of basal cell, and 736 cases of squamous carcinomas arising in the head and neck demonstrates that the basosquamous lesion has the potential to recur and to metastasize, which is similar to squamous cell lesions. An aggressive primary treatment program is recommended.

Effect of subarachnoid morphine on the incidence of spinal headache.

BACKGROUND AND OBJECTIVES: The addition of fentanyl to hyperbaric local anesthetics has been shown to reduce the incidence of post dural puncture headache in the obstetric patient. This study was undertaken to evaluate the effects of subarachnoid morphine on the incidence of headache. METHODS: Eighty-two healthy patients undergoing cesarean delivery with spinal anesthesia were studied. All patients were hydrated with 1500 ml lactated Ringer's solution. Patients were randomly assigned to receive, in a double-blind fashion, 0.2 mg of either morphine (Group 1, n = 40) or saline (Group 2, n = 42) in 0.2 ml volume mixed with 0.75% bupivacaine in 8.25% dextrose plus 0.2 ml 1:1000 epinephrine. Spinal anesthesia was induced using a 25-gauge spinal needle at L3-4 interspace with the bevel, in most cases, parallel to the dural fibers. Patients were followed for three days to evaluate the incidence and severity of headache using a four-category rank scale (none, mild, moderate, severe). Data were analyzed for statistical significance using Student's t-test or chi-square test as appropriate. A p value less than 0.05 was considered significant. Results. The incidence of post dural puncture headache did not differ significantly between groups. Eight patients in Group 1 versus nine patients in Group 2 developed headache (p greater than 0.05). Similarly, the use of blood patch or intravenous caffeine sodium benzoate to treat the headache did not differ significantly between groups. CONCLUSION: It is concluded from our study that subarachnoid morphine did not decrease the incidence of post dural puncture headache in the obstetric patient.

Epidural butorphanol augments lidocaine sensory anesthesia during labor.

To determine the efficacy and safety of epidural butorphanol combined with lidocaine, 50 healthy parturients were studied during labor and delivery. All patients received a test dose of 3 ml 1.5% lidocaine with 1:200,000 epinephrine. Patients were then randomly assigned to receive 7 ml of one of two epidural regimens in a double-blind fashion: Group 1 patients received 1.5% lidocaine plus 1 mg butorphanol plus 1:300,000 epinephrine; Group 2 patients received 1.5% lidocaine plus 1:300,000 epinephrine. Each group consisted of 25 patients. The study ended at the time of redosing. All subsequent epidural injections were made with one bolus of plain 0.25% bupivacaine followed by continuous infusion of 0.125% bupivacaine. Duration of anesthesia was significantly longer for Group 1 compared to Group 2 (p less than 0.01), 124 +/- 8 minutes versus 99 +/- 6 minutes (mean +/- SEM). There were no difference between groups in duration of first and second stages of labor, method of delivery or neonatal outcome. Umbilical cord acid-base status and neurologic adaptive capacity scores did not differ significantly between the two groups. The authors conclude that adding small doses of butorphanol to epidural lidocaine during labor is effective and safe.
