Conflicts, satisfactions, and attitudes during transition to the maternal role.

A correlational descriptive study of 86 first-time mothers examined the relationships among employment status, role conflict, marital satisfaction, employment role attitude, and ease of transition to the maternal role. Interview and questionnaire data were collected 5 to 18 months after the birth of the first child. No significant differences were observed between employed and unemployed mothers in relation to role conflict.

Radiation-associated thyroid tumors: extent of operation and pathology technique influence the apparent incidence of carcinoma.

A prospective study and follow-up program of 2,118 patients with prior low-dose head and neck irradiation, entered into a thyroid screening project, allowed us to examine how the extent of operation and pathology technique influenced the incidence of thyroid carcinoma. Patients with palpable nodular thyroid disease were referred to their physicians with a recommendation for surgery: 107 patients had thyroid surgery in community hospitals (CHs) where enucleation of the nodule or lobectomy was the usual operation, and 29 patients had surgery at Milwaukee County Medical Complex (MCMC) where near-total thyroidectomy was routine. Lymph nodes were sampled in 69% of MCMC operations but in only 16% of CH operations.

Intra-abdominal vascular trauma-a need for prompt operation.

Prompt operative intervention to obtain vascular control is the most important factor in the treatment of intra-abdominal vascular injuries. In 81 patients with major abdominal vascular injuries, bullet wounds were the cause of injury in 51, stab wounds in 12, blunt trauma in ten, shot gun in seven, and one was an iatrogenic injury from insertion of a dialysis catheter. Twenty-nine of 81 patients died (35.

The MEA-I syndrome: an all or none phenomenon?

Studies of two kindreds with the MEA-I syndrome prompted us to challenge the long-standing concept that endocrine involvement in this syndrome may be limited to one or two endocrine glands. Evaluation of medical histories, autopsies, or biochemical screening of 72 family members from five generations suggests that individuals inheriting the trait will develop endocrinopathy in all three endocrine systems characteristically involved in this syndrome, i.e.

The activation of the C3b feedback cycle with human complement components. II. Using components of the alternative pathway.

The C3 convertase of the C3b feedback cycle was generated in the fluid phase from C3b and factors B and D. It was shown to be an effective decomplementing agent when reacted with human serum. Many of the effects observed were dependent on the operation of the feedback during the ongoing reaction.

The activation of the C3b feedback cycle with human complement components. I. Through the classical pathway.

Reaction between the fourth, the oxidized second and the activated first components of human complement generated the stable enzyme C4oxy2 capable of cleaving the third component and depleting total complement in human serum. This enzyme was shown further to activate the C3b feedback cycle as shown by its ability to consume factor B in serum and the reduction in the extent of complement consumption in the presence of EDTA. OxyC2 on its own gave rise to C3 cleavage in normal human serum by a pathway needing classical pathway components.

Effects of de-icing salt on ground water characteristics.

The effect of "road salt" on the characteristics of Massachusetts drinking water supplies has been significant and cumulative rather than transient or seasonal. De-icing salt is essentially all sodium chloride. Calcium chloride accounted for only three percent of the total salt used.
