An unexpected quadruplet heterotopic pregnancy after bilateral salpingectomy and replacement of three embryos

OBJECTIVE: To report a case of combined intrauterine and interstitial twin pregnancies after bilateral salpingectomy and IVF with replacement of three embryos. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 31-year-old woman known to have bilateral salpingectomy for ectopic pregnancies who underwent IVF. INTERVENTION(S): Laparotomy. MAIN OUTCOME MEASURE(S): Postoperation intrauterine monozygotic twins survival and birth. RESULT(S): After removing the interstitial monozygotic twin pregnancy, the patient had an uneventful postoperative course and delivered two healthy girls by cesarean section at 38 weeks' gestation. CONCLUSION(S): Heterotopic pregnancy can still occur in women treated by IVF after bilateral salpingectomy. The early sonography follow-up of IVF pregnancy would be of value because of the reported higher incidence of pathological pregnancies and especially monozygotic twinning.     

Comparison of total laparoscopic hysterectomy and laparoscopically assisted vaginal hysterectomy

We compare the surgical results of 60 women undergoing laparoscopically assisted vaginal hysterectomy (LAVH) and 41 having total laparoscopic hysterectomy (TLH) under the indications of uterine fibroids or adenomyosis. With similar specimen weight, TLH required longer surgery duration (140.4 vs. 115.1 min; p < 0.05) than LAVH. Among women with uteri weighing 0.05) although the TLH group had a significantly higher rate of previous abdominal surgery (57.7 vs. 20%; p < 0.05). There were no significant differences between the two groups with respect to the mean cost, length of hospital stay and rate of various complications (p > 0.05). As for sexual symptoms, dyspareunia decreased significantly post-operatively in the LAVH group (p < 0.05), but not in the TLH group. A significant reduction in the frequency of orgasms after surgery was detected in both groups (p < 0.05). In conclusion, LAVH has advantages over TLH with reduced operating time. Although it is a technical challenge, TLH can be effectively performed within reasonable time limits in selected cases. The effects on sexual function, following either LAVH or TLH, are found to be similar.     

An anomaly within the Latino epidemiological paradox: the Latino adolescent male mortality peak

OBJECTIVE: To describe the anomaly of the Latino adolescent male mortality peak in relation to the overall Latino epidemiological paradox and in relation to the need for new conceptual models describing the health of a culturally diverse population. DESIGN: Population-based study using California's 1989 to 1997 summary death files for death-related information and the State of California Department of Finance population estimates for population denominators for corresponding years. PARTICIPANTS: California's general population for 1989 to 1997, including California's 15- to 19-year-old and 20- to 24-year-old populations. In 1997, those 2 age groups numbered 4.3 million. MAIN OUTCOME MEASURES: Mortality rates for Latinos and African Americans compared with non-Hispanic whites expressed as relative risk (RR). RESULTS: Overall, the Latino RR of mortality follows the Latino epidemiological paradox in that it is lower (RR, <1.00) than that of non-Hispanic whites for most age groups and both sexes. The anomaly within this paradox is seen in Latino males aged 15 to 19 years (RR, 1.77; 95% confidence interval, 1.55-2.02) and 20 to 24 years (RR, 1.79; 95% confidence interval, 1.58-2.02). CONCLUSIONS: This period of elevated mortality risk is labeled the Latino adolescent male mortality peak, and it is an anomaly within the overall Latino epidemiological paradox.     

Morphology,GluR1 and GRIP-C localization differ in octopus cells of C57BL6 and B6Cast mice

Air conduction (AC) versus bone conduction (BC) loudness balance testing was conducted at frequencies of 0.25, 0.5, 0.75, 1, 2, and 4 kHz for two groups: 23 normal hearing subjects and eight subjects with a mild to moderate pure sensorineural hearing loss. Narrow-band noise was presented interchangeably between earphones and a bone transducer fitted to the subjects. Loudness matching was carried out at each frequency and at the levels 30-80 dB hearing level (HL) (10 dB steps) in the following manner: the sound pressure from the earphones was fixed and the subject adjusted the output level of the bone transducer for equal loudness by bracketing the standard. The results revealed somewhat different loudness functions for AC and BC sound with a 6-10 dB difference in the AC and BC loudness functions for the normal hearing group over the dynamic range 30-80 dB HL at the frequencies 250-750 Hz. At the higher frequencies, 1-4 kHz, the difference was only 4-5 dB over the same dynamic range. Similar results were obtained for the sensorineural hearing-impaired group. The difference between the AC and the BC loudness functions may originate from changes with level of the AC sound path, e.g. contraction of the stapedius muscle, but also distortion from the bone transducer and tactile stimulation could have contributed to the results seen.     

Comparison of one- and two-layer vaginal cuff closure and open vaginal cuff during laparoscopic-assisted vaginal hysterectomy

STUDY OBJECTIVE: To evaluate clinical outcomes of three surgical techniques during laparoscopic-assisted vaginal hysterectomy. DESIGN: Prospective, randomized study (Canadian Task Force classification I). SETTING: Medical school-affiliated hospital. PATIENTS: Four-hundred twenty-seven women. INTERVENTION: By means of a computer-generated randomization code, patients were assigned immediately before operation to one of three groups according to type of surgical procedure: group 1, 147 women having one-layer closure of the vaginal cuff; group 2, 138 having two-layer closure of the vaginal cuff; and group 3, 142 having open vaginal cuff. MEASUREMENTS AND MAIN RESULTS: Patients were observed for morbidity during hospitalization, and 1 and 6 weeks and 6 months postoperatively. No significant differences were found among the groups for length of surgery, operative blood loss, postoperative hematocrit, length of hospital stay, postoperative febrile morbidity, frequency of pelvic and urinary tract infection, dyspareunia, postcoital spotting, vaginal discharge, and morbidity of the cuff (cellulitis, abscess formation, bleeding, hematoma, dehiscence). Operating time was greatest for two-layer closure. The frequency of postoperative granulation of cuff tissue and vaginal discharge was greater for group 1 than for the other two groups. CONCLUSION: Two-layer closure of the vaginal cuff during laparoscopic-assisted vaginal hysterectomy is associated with fewer instances of vaginal vault granulation and vaginal discharge than either one-layer closure or open vaginal cuff.     

Evaluation of a non-name-based HIV reporting system in San Francisco

OBJECTIVE: To develop and evaluate a non-name-based HIV reporting system. METHODS: A population-based study of the accuracy of a set of non-name codes and a prospective study of a laboratory-initiated HIV surveillance system conducted at a county hospital (site 1) and a health maintenance organization (site 2). Participants were persons reported with AIDS in San Francisco and patients with a positive test result for HIV antibody, p24 antigen, viral load, or a CD4 count at the study sites. RESULTS: Proper match rate was 95% for records with complete codes and records with at least 50% of the codes. Proper non-match rate was 99% for records with all code elements and 96% for records with at least 50% of the elements. Completeness of reporting was 89% (site 1) and 87% (site 2). Median number of days between test and receipt of test report at the health department was 9 days at site 1 and 7 days at site 2. During 1999, 78% of HIV-infected patients at site 1 and 87% at site 2 had an HIV-specific laboratory test. CONCLUSIONS: A non-name-based laboratory reporting system for HIV is feasible.     

Low socioeconomic status is associated with a higher rate of death in the era of highly active antiretroviral therapy,San Francisco

Highly active antiretroviral therapy (HAART) has dramatically improved survival after AIDS. The benefits of HAART have not been equally realized for all communities, however. We characterize the association of socioeconomic status (SES) with survival after AIDS diagnosis in San Francisco in the period before (1980-1995) and after (1996 - 2001) the wider use of HAART. Using citywide surveillance data, we examined differences in survival after AIDS diagnosis by neighborhood household income using Kaplan-Meier survival analysis and Cox proportional hazards analysis to adjust for significant covariates. Residing in higher SES neighborhoods significantly predicted better survival after AIDS from 1996 to 2001 (hazard ratio = 0.92 per $10,000 increase in neighborhood household income, 95% CI: 0.85-0.99) after adjusting for CD4 count at diagnosis, age, and injection drug user status. Persons living in poorer neighborhoods were less likely to use HAART at any time in the past compared with persons in wealthier neighborhoods. Moreover, no association between survival and neighborhood SES was evident in the era prior to the wide use of HAART. Finally, the difference in survival by neighborhood income level disappeared after controlling for the use of HAART, suggesting that use of or access to treatment explained the association. From 1996 to 2001, survival with AIDS was worse for people living in poorer neighborhoods compared with those living in wealthier neighborhoods of San Francisco as a result of unequal access to or use of HAART.     

Preparation of epoxy-SiO2 hybrid sol-gel material for bone cement

An organic-inorganic hybrid material, epoxy-SiO(2), was prepared by incorporating epoxy structure units covalently into a SiO(2) glass network via the sol-gel approach. The precursor was obtained by the reaction of diglycidyl ether of bisphenol A (DGEBA) with 3-aminopropyl trimethoxysilane (APTS). The precursor was then hydrolyzed and co-condensated with tetraethyl orthosilicate (TEOS) in tetrahydrofuran (THF) at room temperature to yield epoxy-SiO(2) hybrid sol-gel material having a 50 wt % SiO(2) content. Thermal properties of the hybrid material were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The hybrid sol-gel material epoxy-SiO(2) was the solid, powder component of bone cement. The liquid component contains bis-phenol-A glycidyl methacrylate (Bis-GMA), triethyleneglycol dimethacrylate (TEGDMA), and methyl methacrylate (MMA) with 25, 55, and 20 vol %, respectively. We discuss the comparison between the new epoxy-SiO(2) bone cement and the commercial Simplex P bone cement. Mechanical properties such as Young's modulus, compressive strength, hardness, and impact strength of the new epoxy-SiO(2) bone cement exceeded those of Simplex P bone cement. The tensile and bending strengths of the new epoxy-SiO(2) bone cement were approximately the same as those of Simplex P bone cement. In order to evaluate the biocompatibility of the new bone cement, an MTT test and optical microscopy were conducted in cell culture. Results indicated that the new epoxy-SiO(2) bone cement exhibits very low cytotoxicity compared with Simplex P bone cement.
