The Alabama Preterm Birth Study: intrauterine infection and placental histologic findings in preterm births of males and females less than 32 weeks.

OBJECTIVE: The objective of the study was to determine whether there are differences in the placental histology and various markers of infection/inflammation between preterm male and female fetuses. STUDY DESIGN: The placentas and umbilical cords of 446 infants born at 23 to 32 weeks were examined histologically, cultured for aerobic and anaerobic bacteria and mycoplasmas, and the interleukin-6 levels in cord blood determined. RESULTS: Male infants were significantly more likely to have positive placental cultures than female infants (63.4% versus 51.8%, P = .01, odds ratio 1.5, 1.0 to 2.4). Cord blood Mycoplasma hominis and Ureaplasma urealyticum infections were marginally more common in male than female fetuses (27.6% versus 19.2%, P = .06, odds ratio 1.7, 0.9 to 2.9), but cord blood interleukin-6 levels were not different between male and female fetuses. The only significant histologic difference between male and female placentas was in decidual lymphoplasmacytic cell infiltration (6.3% versus 0.9%, P = .003, odds ratio 8.3, 1.8 to 39.0). Males had a higher percentage of decidual lymphohistiocytic cell infiltration, but the differences were not significant (11.3% versus 7.4%, P = .160, odds ratio 1.6, 0.8 to 3.2). CONCLUSION: Male infants were significantly more likely to have positive placental membrane cultures than female infants. Decidual lymphoplasmacytic cell infiltrations were more common in male versus female placentas, confirming a previous observation and suggesting that a maternal immune reaction to fetal tissue may be more common in male fetuses.

The Alabama Preterm Birth Project: placental histology in recurrent spontaneous and indicated preterm birth.

OBJECTIVE: For unknown reasons, a previous preterm birth (PTB) is a major risk factor for PTB in the current pregnancy. Our goal is to evaluate placental histology for clues related to the recurrent nature of PTB. STUDY DESIGN: Four hundred fifty-seven mother/infant dyads delivering between 23 and 32 weeks were first classified as having a spontaneous (S) or indicated (I) PTB, and then sorted into the following mutually exclusive categories by pregnancy history: 1) nulliparous; 2) having no previous PTB; 3) having any previous IPTB; or 4) having a previous SPTB. The placentas were evaluated for acute inflammation in the free membranes, umbilical cord, and chorionic plate, chronic inflammation in the membranes and decidua basalis, thrombosis in the chorionic plate and umbilical cord, and diffuse decidual leukocytoclastic necrosis (DDLN), a lesion associated with decreased placental perfusion. RESULTS: Women who had a SPTB were far more likely (85.5 vs 14.4 P < .0001) to have a SPTB in the previous pregnancy, while women with an IPTB were significantly more likely to have had a previous IPTB (89.7 vs 10.3 P < .0001). Nulliparas and women with previous term births each had about 64% SPTB and 36% IPTB. Acute inflammation at any site was present in 73.9% of SPTB versus 8.0% of IPTB (P < .0001). Chorionic plate thrombosis was also more common in SPTB than IPTB (16.2 vs 7.6, P = .01). Chronic inflammation at any site was more common in IPTB than SPTB (21.0 vs 12.7%, P = .02), as was DDLN (46.5 vs 16.1, P < .0001). When classified by SPTB and IPTB in the current pregnancy, the histologic results were not further influenced by the previous pregnancy history. CONCLUSION: SPTB and IPTB are strongly repetitive. Women with SPTB are significantly more likely to have acute inflammation in the free membranes, chorionic plate, and cord, and chorionic plate thrombosis, while women with an IPTB are significantly more likely to have chronic inflammation and especially DDLN. Past obstetric history does not further influence the placental histology.

The Alabama Preterm Birth study: polymorphonuclear and mononuclear cell placental infiltrations, other markers of inflammation, and outcomes in 23- to 32-week preterm newborn infants.

OBJECTIVE: The purpose of this study was to better understand the relationship between placental polymorphonuclear and mononuclear cell infiltrations with bacterial cultures, markers of inflammation, and preterm outcomes. STUDY DESIGN: This was a prospective study in 446 women who were delivered of a singleton infant at <32 weeks of gestational age. Five placental sites were categorized as having polymorphonuclear or mononuclear infiltrations. Results were compared with placental and cord cultures, umbilical cord interleukin-6 levels, and neonatal outcomes. RESULTS: Polymorphonuclear, but not mononuclear, cell infiltrations were more common at the earliest gestational ages and in black women (56.0% vs 39.3%; P < .01). Polymorphonuclear infiltration was associated with spontaneous preterm birth (73.9% vs 8.0%; P < .0001), but not with preeclampsia (9.9% vs 34%; P < .0001). Women with positive cultures, high interleukin-6 levels, and clinical chorioamnionitis all had significantly more polymorphonuclear infiltrations than did women without those conditions (all probability values, <.0001). In all sites, polymorphonuclear infiltration was associated with neonatal systemic inflammatory response syndrome (P < .0001) and in the cord with necrotizing enterocolitis (22.4% vs 13.5%; P = .02). Intraventricular hemorrhage and neonatal death were not associated with polymorphonuclear infiltration. Polymorphonuclear infiltration at all sites was associated with less respiratory distress syndrome (P < .01). Mononuclear cell infiltration, when present in the decidua basalis, was associated with an increase in neonatal intraventricular hemorrhage (23.8% vs 7.4%; P < .0004). Plasmacytic infiltrates were associated with increased intraventricular hemorrhage (29.4% vs 8.3%; P = .01) and neonatal death (27.8% vs 9.2%; P = .02). CONCLUSION: Polymorphonuclear infiltrations of the free membranes, chorionic plate, and umbilical cord were associated with positive intrauterine cultures and elevated cord blood interleukin-6. There was also an association with systemic inflammatory response syndrome and necrotizing enterocolitis, but not with intraventricular hemorrhage or death, and with decreased respiratory distress syndrome. Decidual mononuclear cell infiltration was associated with an increased risk of intraventricular hemorrhage and decidual plasma cell infiltration with increased intraventricular hemorrhage and neonatal death.

Low-dose-rate vs. high-dose-rate intracavitary brachytherapy for carcinoma of the cervix: The University of Alabama at Birmingham (UAB) experience.

PURPOSE: To review the clinical outcome retrospectively of cervical cancer patients treated definitively with either high-dose-rate (HDR) or low-dose-rate (LDR) brachytherapy. METHODS AND MATERIALS: One hundred sixty patients (44 Stage I, 83 Stage II, and 33 Stage III) were treated from 1990 to 2000 with curative intent for carcinoma of the cervix. One hundred three LDR patients were compared to 57 HDR patients. Two groups were treated during the same period. An external beam dose of 45 Gy to the entire pelvis was delivered at 1.8 Gy per fraction to most patients before the first intracavitary insertion in both groups. Brachytherapy was delivered in one to two LDR implants or four to five HDR implants at 6 Gy per fraction. The prescribed dose to Point A for LDR was at least 80-85 Gy. Patient characteristics were similar for each cohort. Point A doses were similar for each stage. The primary endpoints assessed were survivals and failure sites. Endpoints were estimated using the Kaplan-Meier method and comparisons between treatment groups were performed using the log-rank test. RESULTS: The median followup was 48 months for the LDR group and 59 months for the HDR group. For all stages combined and stage for stage in both groups, there was no statistically significant difference in locoregional control, cause-specific survival, and overall survival for LDR compared with HDR. Locoregional control and overall survival were 78% and 60% for LDR compared to 76% and 55% for HDR at 3 years, respectively (p = 0.96 and p = 0.48). Median cause-specific survival values for LDR vs. HDR were 71 and 81 months, respectively (p = 0.62). The cause-specific survival for LDR patients was 62% compared with 59% for HDR patients at 3 years. For Stage IB2, II, and III LDR patients, cause-specific survival rates were 62%, 67%, and 45%, compared to 67%, 57%, and 33% for HDR at 3 years, respectively (p = 0.75, p = 0.95, and p = 0.48). For patients with a recorded site of first failure, the most common site was locoregional (56%) and then distant metastases (26%). Eight patients who were cancer free developed late complications requiring surgical intervention. Two patients were in the HDR group (3.5%) and 5 in the LDR group (4.8%). CONCLUSIONS: Similar outcome was observed for LDR compared with HDR intracavitary brachytherapy for the entire cohort. In this review, HDR group was not inferior to LDR group in advanced stages. This is likely because our patients were treated with brachytherapy after a high dose of external pelvic radiotherapy in both LDR and HDR patients.

The Alabama Structured Assessment of Treatment Completion for insanity acquittes (The AlaSATcom).

The most complex and risky decisions made by forensic psychiatrists revolve around the decision to release insanity acquittes from custody. This decision has several levels of risk, including the potential liability to the psychiatrist as well as the possible risk to the community. A single bad outcome, even if not predictable, can have disastrous results, not only for victims, but also for the releasing facility. Since predicting violence has so many problems, we chose to look at completeness of treatment instead, so we could say to the Court, "We don't know about violence, but we do know that he has vastly improved." Since many NGRI (Not Guilty by Reason of Insanity) patients spend years in the hospital, they are also expensive. They have rights, as well; therefore the complex assessment must be done as quickly and as accurately as possible. We have developed a spread sheet program to compare these multiple factors, and have compared it against the clinical decisions we have made in more than 100 discharges. We believe this gives a framework for decision-making that will increase the consistency of this process.

Idiopathic hirsutism: an uncommon cause of hirsutism in Alabama.

OBJECTIVE: To determine the prevalence of idiopathic hirsutism among a population of consecutive hirsute patients. DESIGN: Prospective cohort study. SETTING: University-based clinic. PATIENT(S): Premenopausal women with a complaint of hirsutism who were not receiving hormonal therapy. INTERVENTION(S): Evaluations for total and free testosterone, (T), 17-hydroxyprogesterone (17-HP), and DHEAS serum levels. MAIN OUTCOME MEASURE(S): Ovulatory function in women with cycles of < or =35 days in length was assessed with a basal body temperature (BBT) calendar and day 22-24 progesterone levels. RESULT(S): Of 132 consecutive hirsute women studied, 68 had cycles of >35 days in length. Of the remaining 64 patients, 25 also had oligo/anovulation by BBT and day 22-24 progesterone level. Of the 39 patients with hirsutism and regular ovulatory function, 22 had total and free T and DHEAS levels within normal limits. CONCLUSION(S): If idiopathic hirsutism is defined by the presence of hirsutism, regular ovulation, and normal androgen levels, only 17% of consecutive hirsute patients can be diagnosed with the disorder. Alternatively, if idiopathic hirsutism is based solely on the presence of hirsutism and regular ovulation, regardless of androgen levels, then 29% of the total hirsute population can be considered as having idiopathic hirsutism. Importantly, 40% of hirsute patients with a history of "regular cycles" were actually oligo/anovulatory, indicating the need to objectively assess ovulatory function in such patients.

Clonidine poisoning in Jefferson County, Alabama.

STUDY OBJECTIVE: To describe the epidemiology of clonidine-related hospitalization in children, to evaluate the efficacy of naloxone, and to review the clinical effects of clonidine toxicity. METHODS: This was a retrospective analysis in an urban teaching pediatric emergency department with an annual census of 55,000 involving 80 children younger than 6 years who were admitted for clonidine ingestion during a 6-year period. RESULTS: Clonidine commonly belonged to the patient's grand-mother (54%). Black children were twice as likely to be hospitalized for clonidine ingestion than white children compared with children hospitalized for any injury. Average time to onset of symptoms was 35 minutes. Decreased level of consciousness was the most common presenting symptom (96%). Mean ED vital signs were systolic blood pressure, 102 mm Hg; pulse, 98; respirations, 25 (six patients intubated); and temperature, 36.6 degrees C, Naloxone was administered to 49% of patients, 84% of whom demonstrated no response. CONCLUSION: Clonidine ingestion is endemic in our area. Serious clinical effects mandate that all children with clonidine ingestion be triaged to a health care facility. Naloxone as an antidote for clonidine remains controversial.

The University of Alabama Teenage Access Project: a model for prevention, referrals, and linkages to testing for high-risk young women.

The Teenage Access Project (TAP) was supported by the Special Projects of National Significance Program to expand and ensure access to health and support services for disadvantaged, human immunodeficiency virus (HIV)-positive, and at-risk adolescent and young adult women aged 10-21 years by: (a) preventing further HIV transmission through empowerment and reduction of risk behavior, (b) providing HIV counseling and testing to increase screening of young women, and (c) facilitating referrals to medical and psychosocial services through the TAP activities. TAP served 403 young people (82% African-American and 83% young women). The basic elements of the TAP service model components were: (a) outreach to community agencies serving high-risk, disadvantaged young women; (b) My Individual Responsibility Reduces Our Risk (MIRROR), a six-module risk-reduction and empowerment activity specifically designed for young women in Jefferson County, using a small group format; and (c) the Adolescent Testing Center (ATC), a center for age and culturally appropriate HIV testing, pre- and posttest counseling, risk assessment, and referrals. HIV testing and pre- and posttest counseling were provided confidentially in both clinical and community settings. More than 200 participated in the MIRROR activity. A total of 101 young women received HIV counseling and testing services.
