The relative absence of riots in colonial Mexico City is an intriguing phenomenon which has attracted the recent attention of scholars interested in questions of social stability and conflict. While the Mexican countryside experienced over 130 rebellions in the eighteenth and early nineteenth centuries, the cities by comparison remained calm. The most cogent explanation of urban lower class passivity during the late colonial period has been formulated by Eric Van Young, who suggests that a number of short- and long-term social and economic forces converged to keep the cities, most notably Mexico City, relatively quiet during the wars for independence. Among those he noted were the existence of urban social service and food-distribution institutions, the presence of security forces, an atomized and fluid social order, the lack of traditional communal rights to defend, and weak organizational means to focus discontent.

Objective: Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. Methods: From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue - mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. Results: There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT - with follow-ups averaging two years (0.5-8) - are receiving thyroxin substitution. Conclusions: There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.
