Inscribing a lesbian reader, projecting a lesbian subject: a Jane Rule diptych.

This diptych represents two takes on the short fiction of Jane Rule, the Canadian lesbian novelist whose 1964 novel, Desert of the Heart, was markedly different from other lesbian fiction available at that time. Traveling through time, theory, and texts, I approach Rule's fiction from two directions. First, using feminist maps for (re)reading, I show how "Dulce" inscribes a lesbian reader. Second, tracing the steps of lesbian and queer theorists, I show how "Home Movie" projects a lesbian subject. Taken together, these readings seek to shed light on lesbian creative practice in the homophobic climate of postwar North America.

Crack and aortic dissection.

Aortic dissection represents a medical and, potentially, surgical emergency. Hypertension and cystic degeneration of the media are predisposing risk factors in the pathogenesis. Sporadic reports of aortic dissection in association with drug abuse especially crack cocaine are now appearing. We present such a patient whom we recently treated at University of Wisconsin Hospital.

Abdominal abscesses associated with enteric fistulas: percutaneous management.

For many years, surgical dictum stated abdominal fistulas should be treated by means of surgical excision. Recent advances in percutaneous techniques have altered this. The authors reviewed 150 consecutive abdominal abscesses drained percutaneously over a 36-month period. Among these, 24 patients were found to have 26 fistulous communications to bowel, the pancreatic duct, or the biliary system. Initial drainage of their abscesses was performed in the hospital, but 17 of 24 patients were discharged with a tube in place and were followed up as outpatients. The duration of drainage ranged from 4 days to 3 months. Fistulas healed in 21 of 24 patients (88%) without surgical intervention. Complications were few and included inadvertent dislodgment requiring tube replacement (two patients) and inadvertent puncture of the transverse colon (one patient). Treatment of abdominal abscesses with fistulas by means of percutaneous methods is reliable and safe. Hospital stay may be minimized with outpatient management after drainage.

Effect on the seizure threshold in dogs of tocainide/lidocaine administration.

Oral lidocaine analogues, such as tocainide, recently have been introduced to treat cardiac arrhythmias. The side effects of tocainide are similar to those of lidocaine, but possible interactions with lidocaine have not been examined thoroughly. With the increased use of these agents, emergency physicians must decide the safety of concurrent administration of lidocaine for local anesthesia or arrhythmia management. Twelve dogs were assigned randomly to either a lidocaine (L) or a tocainide/lidocaine (TL) group. The L group received lidocaine at a dosage of 0.5 mg/kg/min until the animals seized. The TL group received both loading and maintenance doses of tocainide to obtain therapeutic steady-state tocainide levels prior to receiving lidocaine at a dosage of 0.5 mg/kg/min. Venous blood samples to measure drug levels were obtained at 20-minute intervals and at the time of seizures. The average duration of lidocaine administration required to induce seizures in the L group was 70.0 +/- 7.5 minutes, and in the TL group 29.0 +/- 7.0 minutes (P less than .05). In addition, the average serum lidocaine level at the time of seizures was 11.2 +/- 1.0 micrograms/mL in the L group and 6.2 +/- 1.7 micrograms/mL in the TL group (P less than .05). Our results show that in animals the presence of a therapeutic serum level of tocainide lowers the seizure threshold following the administration of lidocaine. These findings may have important implications for clinical care because they suggest that lidocaine should be used cautiously and in reduced dosage in patients already taking tocainide.
