The "lytic cocktail" induces recurrence of fits in the treatment of eclampsia

To the Editors: We feel that the "lytic cocktail" must be banned in

the treatment of eclampsia. In an effort to control 30 patients with eclamptic seizures, the Obstetrics Clinic of the Paulista Medical School administered a combi­nation of chlorpromazine and promethazine ( l 00 to 400 mg of each drug per 24 hours) and an intravenous priming dose of pethidine ( lOOmg/24 hr), diluted in a 5% glucose solution. This mixture of drugs proved to be a "cocktail" that induced recurrence of seizures rather than stopping them (Table I).

We have divided the cases into four groups as a func­tion of the grade of severity. Group A (Fig. 1) consisted of 12 patients with low arterial blood pressure levels who continued to have seizures throughout labor until their babies were delivered. Group B (Fig. 2) involved three patients who remained convulsive after delivery. Group C (Fig. 3) consisted of 11 eclamptic patients who experienced seizures during labor and the first 20

hours puerperium while being treated with the "lytic cocktail." Seizures stopped when this therapy was aban­doned. The only case of maternal mortality occurred in the latter group. The patient suffered 29 seizures

and died 2 hours after a cesarean section as she was receiving a blood transfusion for operative shock and 250 mg of thiopentane in an attempt to stop the sei­zures. There were four patients in group D (Fig. 4)

whose seizures stopped after delivery. One patient in this group had 39 seizures. The rate of intravenous dripping was governed by patient response, and par­adoxically, in some cases the increasing of dripping resulted in an increase in the number of convulsions.

It seems likely that the combination of phenothia­zines and pethidine is a convulsant therapy in eclamp­sia. There was a reduction in systolic pressure (Figs. 1-4) without a relevant decrease in diastolic pressure in most of the eclamptic patients. These observations were made for a very elevated cardiac rate (pulse up to 160 bpm). These clinical data suggest that there is a de­crease in blood flow in the brain. These findings rein­force the hypothesis of Sheehan and Lynch' that con­vulsions result from a vasomotor disturbance.

Coincidence of congenital aplasia of the vagina with ear and facial anomalies

To the Editors: I read with interest the article by Winer-Muram et

al. (Winer-Muram HT, Muram D, Wilroy RS, Cupp C. The concurrence of facioauriculovertebral spectrum and the Rokitansky syndrome. AMJ 0BSTET GYNECOL

1984; 149:569.) The statement that "the concurrence of the facioauriculovertebral spectrum and the Rokitan­sky syndrome has not been previously described" is not correct. A similar case has been published before.'

Reply to Willemsen To the Editors:

This letter is being written in reply to Dr. Willemsen's comments about the article, The concurrence of fa­cioauriculovertebral spectrum and the Rokitansky syn­drome. The cases are similar, and indeed Dr. Willem­sen's comments are entirely justified. Our patient was seen and written up in October, 1982, at which time we were unaware of Dr. Willemsen's article which had

not been published as yet. The similarity of these two cases supports the hypothesis that a spectrum of mes­enchymal defects indeed exists.

We would like to thank Dr. Willemsen for his comments.

Prognostic significance of adenofibromatous pattern in ovarian epithelial malignancies

To the Editors: I read with great interest the article of Malkasian et

al. "Prognostic significance of histologic classification and grading of epithelial malignancies of the ovary" (AM J 0BSTET GYNECOL 1984; 149: 27 4), and would like to make the following comment.

Apart from stage, grade, and cell type, which have been studied and discussed by the authors, there is another factor that has not been mentioned at all, i.e., the presence or absence of adenofibromatous or cyst­adenofibromatous pattern. This histologic variant, which is more common with the serous cell type than with the other cell types of ovarian epithelial malig­nancies, has been listed as a separate subdivision in the World Health Organization classification. 1 Most prob­ably, in cases with this histologic variant the malignant epithelium induces an increased stromal cellularity, and as a consequence of this, the tumor exhibits histologi­cally a prominent fibrous stroma. It should be empha­sized that the stroma does not show any degree of atyp­ism or mitotic activity, thus ruling out the possibility of Miillerian adenosarcoma. Unfortunately, the prognos­tic significance of the presence or absence of adenofi­bromatous or cystadenofibromatous pattern in ovarian epithelial malignancies is still not known and yet has to be determined.

Reply to Piura To the Editors:

The presence of epithelial malignancies of the ovary in association with adenofibromas or buried within these lesions has been known for some time. The ac­tivity of these lesions appears to be associated with the
