MR imaging of hemorrhagic adnexal masses.

Magnetic resonance (MR) imaging, performed on 31 women with 40 surgically proven adnexal masses, was reviewed to determine whether MR can distinguish hemorrhagic from nonhemorrhagic masses. Fourteen masses proved to be hemorrhagic at surgery including functional ovarian cysts (seven cases), cystadenoma (one case), endometriomas (three cases), hematosalpinx (one case), ectopic pregnancy (one case), and parametrial extension from cervical carcinoma (one case). A high signal intensity (compared with adjacent pelvic fat) on a T1-weighted spin echo sequence was found to be a reliable indicator of hemorrhage and was demonstrated in all 14 hemorrhagic masses. The "hematocrit" effect was seen as an area of high signal intensity layering in the dependent portion of six hemorrhagic cysts. Only four of 26 nonhemorrhagic masses demonstrated high signal intensity on T1-weighted sequences and, of these, three proved to be fat-containing dermoid cysts and one was a simple cyst with adherent mesenteric fat. We conclude that high signal intensity on a T1-weighted spin echo pulse sequence is evidence for a hemorrhagic mass and that a hematocrit effect appears to be a specific sign for a hemorrhagic cyst. The clinical significance of hemorrhagic adnexal masses is discussed.

Adnexal Diseases

Dacryocystorhinostomy.

The extranasal method of dacryocystorhinostomy, which totally incorporates the lacrimal sac into the nasal cavity, is described, and the primary and late results of this method are presented in 57 patients with chronic epiphora caused by stenosis of the nasolacrimal duct. Immediately after the operation, the results were satisfactory in all patients. At late follow-up, with a median observation period of 5 years, 80% of the patients were completely free of epiphora and 15% had periodic epiphora, which was a considerable improvement over the preoperative condition. The described method could become a rhinologic routine procedure in patients with chronic epiphora.

Social surveys and health policy implications for national health insurance.

The authors explore the utility of applying social survey data (a) to evaluate the impact of existing health programs and (b) to rank-order priorities concerning future health care policies. Based on national survey data from 1963, 1970, and 1976, they concluded that although Medicare and Medicaid have enabled more people to see a physician than ever before, a large proportion of the population still registers dissatisfaction with the health care they received--particularly with respect to their out-of-pocket costs for obtaining it. However, national health insurance options favored by the majority of the population--particularly those who can best afford the cost of care--suggest preferences for programs that incorporate some mix of existing modes of financing rather than those that provide for substantial restructuring of the current system.
