Breast tumour thymidine kinase levels and disease recurrence.

Thymidine kinase (TK) exists in two forms, TK1 and TK2. TK levels and oestrogen receptor status (OR) were measured in tumours from 86 patients with operable breast cancer and the patients were monitored for recurrence over 24 months. During the monitored period, 13 patients showed recurrence. These patients also exhibited higher total TK levels per mg tumour (P < 0.01) and higher TK1 levels (P < 0.001) than those who did not show recurrence. TK1 levels relative to TK2 were significantly higher (P < 0.05) in OR-negative tumours (n = 29) than in OR-positive tumours (n = 57). OR-negative (n = 9) and OR-positive (n = 4) patients who recurred had significantly higher TK1 levels relative to TK2 than did those who not recur (n = 20 and n = 53, respectively). These preliminary results indicate that breast tumour TK levels may have value in determining prognosis.     

Ileal pouch-anal anastomosis for chronic ulcerative colitis. Long-term results.

The aim of this study was to determine the long-term outcome among 390 patients with ulcerative colitis who underwent ileal J pouch-anal anastomosis and whether patient or operative factors influenced results. The combined operative morbidity rate for the pouch-anal anastomosis and the subsequent closure of the temporary ileostomy was 29% (bowel obstruction, 22%; pelvic sepsis, 5%), with one death due to pulmonary embolus. The probability of a successful outcome at 5 years was 94%. Of the 24 patients who failed (6% of total), 18 did so within 1 year (4%), three during year 2 (1%), three during year 3 (1%), and none thereafter. Stool frequency (7 stools/24 h), the occurrence of pouchitis (14%), and satisfactory daytime continence (94% of patients) remained stable over 4 years after operation, whereas nocturnal fecal spotting decreased (51% of patients to 20%). Women had more spotting than men, whereas patients over 50 years old had more stools per day than those 50 years or younger. In conclusion, ileal pouch-anal anastomosis achieved a reasonable stool frequency and satisfactory continence in patients with ulcerative colitis over the long-term. These results support the ileal pouch-anal anastomosis as a safe, satisfactory alternative to permanent ileostomy.     

Acute ischemic stroke review.

More than 700,000 people have a stroke each year in the United States. A diagnosis of stroke formerly elicited a nihilistic approach, but this has substantially changed in the last decade. Currently, time is brain, and it is important for all disciplines to work together to initiate acute stroke protocols in the emergency department and identify patients within the therapeutic time window for thrombolytic and neuroprotective therapies. Evolving protocols, management, and nursing care all have important implications during the acute phase of ischemic stroke. Patient and family education on risk reduction must also be addressed by the entire healthcare team.     

A stereotactic approach to deep-seated central nervous system neoplasms using the carbon dioxide laser

This report describes a technique in which deep-seated CNS neoplasms, the volume and shape of which had been determined and stereotactically localized by computer reconstruction of CT data, were vaporized with a carbon dioxide laser attached to a stereotactic frame. The clinical results with 6 patients treated by this technique are presented.     

Informational needs of individuals and families with hereditary cancers

Individuals and families with hereditary cancers have informational needs that differ, depending on the availability of testing for increased hereditary risk and major focus of concern (reproductive decision-making or risk to self). Cancer risk counseling helps individuals understand risk information so they can make decisions appropriate to their lives and value systems.     

Placental teratoma.

The rare teratoma of the placenta has been compared to the fetus amorphus, two distinguishing characteristics being the teratoma's lack of structural organization and lack of large vessels entering the tumor. A case of placental teratoma and theories of origin are discussed.
