Question: Abstract: We correlated the level of vitiligo antibodies to the extent of depigmentation in thirty-two patients with vitiligo. Vitiligo antibodies were assayed by protein A-sepharose immunoprecipitation method. Antibodies were present in four of eight (50%) patients with minimal vitiligo (less than 2% body surface involved), in nine of ten (90%) patients with moderate vitiligo (2 to 5% surface involved), and in thirteen of fourteen (93%) patients with more extensive disease (greater than 5% surface involved). The level of vitiligo antibodies in the three groups expressed as a binding index was 2.9% +/- 2.03, 5.6% +/- 2.92, and 8.0% +/- 3.03 SD, respectively. These results suggest that there is a relation between the incidence and level of vitiligo antibodies and the extent of depigmentation in vitiligo.

Answer: Correlation between vitiligo antibodies and extent of depigmentation in vitiligo.

Question: Abstract: The nature of false labor and its influence on the subsequent course of true labor was examined by a retrospective case-controlled matched study of 83 patients admitted in false labor. Patients with a history of false labor had a significantly greater incidence of dysfunctional labor when true labor did commence. The frequency of cesarean section was also higher, though not statistically significantly so. The dilatation of the cervix and the station of the presenting part at admission were both significantly different in patients with false labor from those in true labor; however, the overlap of these two groups makes this of limited clinical use. Time of day and day of the week did not correlate with the likelihood of being admitted in false labor.

Answer: False labor.

Question: Abstract: A review of 77 patients with traumatic central cord syndrome revealed that atypical variations are more common than the existing literature suggests and that these may be seen in a wide variety of acute injuries to the cervical spine. In general the outcome is good; a favourable prognosis on admission is suggested by good hand function, hyperpathia, Lhermitte's sign and normal perianal sensation. The study has highlighted the value of regular muscle charting and has cast doubt on previous neuroanatomical assumptions about the syndrome.

Answer:
A reappraisal of acute traumatic central cord syndrome.
