Impact of round-the-clock, rapid oral fluid HIV testing of women in labor in rural India.

Background Testing pregnant women for HIV at the time of labor and delivery is the last opportunity for prevention of mother-to-child HIV transmission (PMTCT) measures, particularly in settings where women do not receive adequate antenatal care. However, HIV testing and counseling of pregnant women in labor is a challenge, especially in resource-constrained settings. In India, many rural women present for delivery without any prior antenatal care. Those who do get antenatal care are not always tested for HIV, because of deficiencies in the provision of HIV testing and counseling services. In this context, we investigated the impact of introducing round-the-clock, rapid, point-of-care HIV testing and counseling in a busy labor ward at a tertiary care hospital in rural India. Methods and Findings After they provided written informed consent, women admitted to the labor ward of a rural teaching hospital in India were offered two rapid tests on oral fluid and finger-stick specimens (OraQuick Rapid HIV-1/HIV-2 tests, OraSure Technologies). Simultaneously, venous blood was drawn for conventional HIV ELISA testing. Western blot tests were performed for confirmatory testing if women were positive by both rapid tests and dual ELISA, or where test results were discordant. Round-the-clock (24 h, 7 d/wk) abbreviated prepartum and extended postpartum counseling sessions were offered as part of the testing strategy. HIV-positive women were administered PMTCT interventions. Of 1,252 eligible women (age range 18 y to 38 y) approached for consent over a 9 mo period in 2006, 1,222 (98%) accepted HIV testing in the labor ward. Of these, 1,003 (82%) women presented with either no reports or incomplete reports of prior HIV testing results at the time of admission to the labor ward. Of 1,222 women, 15 were diagnosed as HIV-positive (on the basis of two rapid tests, dual ELISA and Western blot), yielding a seroprevalence of 1.23% (95% confidence interval [CI] 0.61%–1.8%). Of the 15 HIV test–positive women, four (27%) had presented with reported HIV status, and 11 (73%) new cases of HIV infection were detected due to rapid testing in the labor room. Thus, 11 HIV-positive women received PMTCT interventions on account of round-the-clock rapid HIV testing and counseling in the labor room. While both OraQuick tests (oral and finger-stick) were 100% specific, one false-negative result was documented (with both oral fluid and finger-stick specimens). Of the 15 HIV-infected women who delivered, 13 infants were HIV seronegative at birth and at 1 and 4 mo after delivery; two HIV-positive infants died within a month of delivery. Conclusions In a busy rural labor ward setting in India, we demonstrated that it is feasible to introduce a program of round-the-clock rapid HIV testing, including prepartum and extended postpartum counseling sessions. Our data suggest that the availability of round-the-clock rapid HIV testing resulted in successful documentation of HIV serostatus in a large proportion (82%) of rural women who were unaware of their HIV status when admitted to the labor room. In addition, 11 (73%) of a total of 15 HIV-positive women received PMTCT interventions because of round-the-clock rapid testing in the labor ward. These findings are relevant for PMTCT programs in developing countries.

Surface area of chorionic villi of placentas: An index of intrauterine growth restriction of fetuses

Aim:  Histomorphometric studies of placentas from idiopathic intrauterine growth restricted (IUGR) fetuses as well as normal‐weight (control) fetuses were performed to determine surface area of chorionic villi (mostly terminal and few intermediate) using stereological technique. The results were compared to determine the difference in the values of surface area of chorionic villi, and to establish any relationship between placental histomorphometric changes and IUGR.

Simultaneous triple point-of-care testing for HIV, syphilis and hepatitis B virus to prevent mother-to-child transmission in India

An innovative simultaneous triple point-of-care (STPOC) screening strategy for syphilis, hepatitis B and HIV with Determine® tests was offered to pregnant women presenting for antenatal care and evaluated for feasibility and preference in rural India. Of 1066 participants approached, 1046 consented, of which 1002 (96.0%) completed the strategy. Only 9% reported any history of testing in their current pregnancy. With STPOC screening, 989 women (98.7%) tested negative and 13 had preliminary positive results for infection. The total time taken was 45 minutes per participant. Mothers and infants were provided prophylaxis/treatment for HIV, syphilis and hepatitis B, with interventions initiated within 3–5 days. STPOC was preferred by 99.3% (95%CI: 98.8–99.8%) of participants, facilitated early simultaneous screening for the three infections, timely initiation of prophylaxis/treatment and was feasible in this rural setting. These data suggest that multiplexed STPOC screening for syphilis, hepatitis B and HIV in pregnancy would be desirable for women in rural India.

Fertility Preservation in Gynecological Cancers

For cancers of reproductive system in women, fertility preservation is complex. Fertility is also affected by therapies, however prevention is possible. Radiotherapy affects gonads, uterus, and subsequent pregnancy outcomes in all ages. However, degree and damage depend on dose, irradiation field, and age at the time of exposure. Ovarian transposition is considered if ovarian involvement is unlikely. Gonadotoxic effects of chemotherapy are related to agents type, cumulative doses, age, and ovarian reserve. Some agents are highly toxic. Rendering follicular development quiescent by suppression of gonadotropins does reduce the ovarian damage. Simple or radical trachelectomy can be used in early cervical cancer. Fertility saving surgery is possible only in early stage low grade epithelial cancers of the ovary, however, in germ cell tumors even in advanced stages it may be possible to preserve fertility. There are no standard recommendations for endometrial cancer. Embryo, oocyte, and ovarian tissue cryopreservation are possible. The human embryo is very resistant to damage. In view of these possibilities, it is advocated that attention to long term health and quality of life in gonadotoxic therapy must be incorporated into plans as early as possible.

AmniSure: A Point of Care Diagnostic for Preterm, Term Prelabor Rupture of Membranes

Background: Accurate, early diagnosis, prompt appropriate intervention is essential in the management of rupture of membranes (ROM), especially preterm. Aim: The aim was to determine efficacy of AmniSure rapid immunoassay placental alpha-microglobulin-1 test for accurate diagnosis of true ROM in women with watery discharge after 28 weeks gestation, compare with conventional methods. Subjects and Methods: Study was carried out in women presenting with ROM to labor the room of referral rural medical institute in Central India after ethical approval. Prospective study was performed in women presenting with symptoms/signs of ROM after 28 weeks of gestation. Sterile speculum examination was performed to observe pooling of liquor. Nitrazine, ferning tests were done to diagnose ROM. Vaginal examination was performed to determine cervical dilatation, effacement, station of presenting part in term cases. If all or 2 of 3 tests (pooling, ferning, and nitrazine) were positive, provisional diagnosis of ROM was made. Confirmation of ROM was done at birth. However, if 2 of 3 tests were negative, sterile speculum examination was repeated after 30 min of the first test. Test performance was calculated by comparing AmniSure results against final diagnosis at birth. Of 200 patients between 28 and 42 weeks gestation recruited for study, 31.5% (63/200) were preterm, 68.5% (137/200) term. Statistical analysis of data collected in the electronic database using SPSS version (Amnisure International LLC, 30 JFK Street, 4th Floor, Cambridge, MA 02138, USA). Results: AmniSure rapid immunoassay, rapid method for diagnosis of ROM, has 100% specificity, 99.44% sensitivity (one false negative due to meconium and immediate cesarean section). Conclusion: In comparison to nitrazine, pooling, ferning, AmniSure has almost 100% sensitivity, specificity.

Rationale use of blood and its components in obstetric-gynecological practice

Appropriate and rational use of blood/components is essential for ensuring availability for the needy as well as preventing risks of transfusion-transmitted diseases and saving resources. Rational use means providing the right blood or products, in the right quantity, to the right patient and at the right time, bridging demand, and supply gap. The safety, adequacy, and effectiveness can only be achieved if unnecessary transfusions can be prevented. Further, risk can be reduced, but cannot be eliminated completely. Alternative to banked blood, autologous blood donation, normovolemic hemodilution, and intraoperative cell salvage should be considered as possible options. Recombinant factor VIIa is a new adjunct for treatment of massive hemorrhage and should be considered, if available.

Health hazards among health care personnel

While providing health services, (preventive, curative, rehabilitative), health care personnel (HCP) face hazards. Developments in medical science provide some safety, still modern technology has made health care very complex with many hazards. Biological (viruses, bacteria, and parasites) and chemical (disinfectants, drugs, and diagnostics) therapeutic modalities in health delivery are leading to many disorders in HCP. Needle prick injuries, radiation exposure, violence, psychiatric disorders, stalking by patients, and suicides are common. HCP are at high risk for musculoskeletal disorders, due to patient handling, compounded by increasing number of obese patients. With increase in workload because of human immunodeficiency virus, hardships have increased. Despite potential for exposure to hazards, many HCP lack awareness about prevention. Also the system is not conducive, policies of prevention not clear, inaccessibile, or there is attitude problem. Hence, HCP continue to suffer, more in developing countries. Health managers need to ensure that health care is geared toward assessment of hazards suffered by HCP, there reasons, and do everything possible for prevention.

Essentialities of knowledge of whys and whats of acute abdomen during pregnancy

Acute abdomen accounts for 5-10% of emergency department visits. It designates symptoms, signs of intraperitoneal disease with sudden onset, can persist for hours to days, and is associated with wide variety of clinical features which may not be, specific to underlying disease. Pregnant state complicates the issue because of anatomic, physiologic changes during pregnancy. Its causes are many, obstetric, gynecological, many others which encompass a wide spectrum of surgical and medical conditions from aortic dissection to psychogenic pain, almost anything in between, a trivial to life-threatening condition, which requires immediate therapy. Diagnosis is challenging, requires careful history, thorough evaluation of symptoms, examination, and judicious use of investigations to specify disease and management which many times could be surgery only. Individualized approach is the best with basics known.

Trends in Hysterectomy for Genital Prolapse: Rural Experience

The present study was conducted to investigate the trends of vaginal hysterectomy for genital prolapse in last 20 years by analyzing case records of affected women. During the analysis period, 4831 women underwent hysterectomy; records of 4223 (87.5%) were available. Of these, 911 (21.6%), 2.7% of 34,080 gynecological admissions, had vaginal hysterectomy for genital prolapse (study subjects). Eighty percent women who had vaginal hysterectomy for genital prolapse were over 40 years of age; however, most of these women had had the disorder for years before they presented. Only 4 (0.4%) women had not given birth, 874 (96%) women had had two or more births, and 383 (42%) had had 5 or more births. Having given birth was the major factor responsible for genital prolapse. In all, 94.2% of women presented with something coming out of the vagina.” Some women presented with abnormal vaginal bleeding or pain in abdomen as the chief complaint although they had had uterovaginal prolapse for years. There was no mortality and morbidity decreased over the years. There has been no change in the rate of vaginal hysterectomy for genital prolapse over the years. Surgical morbidity decreased trend, possibly because of the preoperative, intraoperative, and postoperative precautions taken, especially preoperative treatment of urinary and genital tract infection. Attempts need to be made to have safe births and a healthy life style so as to prevent genital prolapse and in case it occurs, therapy to prevent progression so that major interventions like hysterectomy are averted. Meticulous preoperative evaluation and planned therapy help in reducing surgical morbidity, if surgery becomes essential.
