Dental services, costs, and factors associated with hospitalization for Medicaid-eligible children, Louisiana 1996-97.

OBJECTIVE: This study compared types and costs of dental services rendered to children who had received care in a hospital operating room (H) with children who had not (NH). METHODS: The study population consisted of all children aged 1-5 years who received a dental service reimbursed by the Louisiana Medicaid EPSDT program from October 1996 through September 1997. Claim files were provided by the Louisiana Bureau of Health Services Financing. A treatment intensity index [TII = 3 x (# extractions) + 2 x (# pulpotomies + # crowns) + # simple restorations] was calculated for H children (n = 2, 142) and NH children (n = 38,423). Using logistic regression, a dichotomous hospitalization variable (H vs NH) was regressed against treatment intensity and selected personal and parish (county) characteristics for each of the five age groups. Total and average reimbursement per child were calculated for both groups of children, by age. RESULTS: The mean treatment intensity scores for H and NH children were 24.02 (SD = 11.82) and 2.16 (SD = 4.78), respectively. For all age groups, children with treatment intensity scores greater than 8 were at least 132 times more likely to be hospitalized than were children with scores less than or equal to 8. The mean cost for care provided to H children was $1,508 compared with $104 for NH. Total costs for dental care rendered to H children (5% of the study population) were $3,229,851 (45% of total dental costs for the study population). CONCLUSION: Reducing severe caries through early interventions could provide substantial cost savings.

Subendometrial contractility in menstrual phase visualized by transvaginal sonography in patients with endometriosis.

OBJECTIVE: To describe the propagation direction of the subendometrial myometrial contractile wave in menstrual phase sonographically assessed in patients with and without endometriosis. DESIGN: Prospective study. SETTING: Patients and normal volunteers in a university hospital. PATIENTS: Sixteen women with (study group) and 21 without (control group) endometriosis. INTERVENTIONS: Patients were examined by transvaginal sonography (midsaggital plane of the uterus) and recorded on videotape for a 5-minute period. MAIN OUTCOME MEASURE: Direction of propagation of contraction waves. RESULTS: The endometriosis group showed a predominant retrograde pattern whereas the control group showed a normal antegrade. CONCLUSION: This abnormal cervix-to-fundus myometrial activity could well increase the amount of peritoneal shedding of endometrial menstrual debris, increasing the probabilities of its heterotopic implantation.

Epithelioid leiomyoma of the vulva.

An ultrastructural and light-microscopic study of the second published case of epithelioid leiomyoma of the vulva is reported. The tumor occurred in the right labium minus of a 26-year-old nonpregnant female. Optic microscopy revealed a clear cell neoplasm with a marked relationship to arterial vessels from which it may originate. The ultrastructure was analogous to that of similar cases reported in the uterus and stomach.
