Identification and Classification of Postpartum Psychiatric Disorders

1. Postpartum depression has been used as a catchall phase for many postpartum emotional symptoms. Categorizing a number of diverse disorders under one title has resulted in an inability to identify who is most at risk for developing postpartum problems. 2. The postpartum period is a particularly vulnerable period for depression, despite the fact that it is perceived as a time of joy and emotional well-being. 3. By increasing awareness among all health care professionals who care for women during the period following childbirth, postpartum psychiatric disorders can be identified early and treated correctly. 4. Limiting postpartum psychiatric disorders to postpartum depression may result in limited or inappropriate treatment options.

Sentinel lymph node detection and microstaging in vulvar carcinoma

OBJECTIVE

To determine the efficacy of using complementary techniques for detecting sentinel lymph nodes (SLNs) in vulvar carcinoma and to evaluate the utility of microstaging techniques.

STUDY DESIGN

Patients with invasive vulvar carcinoma underwent sentinel lymph node detection (SLND) using preoperative lymphoscintigraphy, intraoperative isosulfan blue dye injection and an intraoperative hand-held gamma-detecting probe. Eleven patients were included and a total of 16 groins evaluated. Sentinel nodes identified were excised, bisected and examined in surgical pathology using hematoxylin and eosin (H&E) staining. Pathologically negative SLNs were subjected to additional microstaging via serial sectioning and immunohistochemical staining for cytokeratin. Surgical management of the vulvar cancer and extent of inguinal-femoral lymphadenectomy were individualized based on clinicopathologic parameters, including depth of invasion, location of the tumor and patient performance status.

RESULTS

Lymphoscintigraphy, dye and gamma-detector methods led to the total detection of 16, 19 and 17 SLNs, respectively. In two cases the isosulfan blue dye assisted in the isolation of an additional sentinel node over that of the gamma probe. Each method individually identified SLNs in 10/11 patients (91%). A total of 19 sentinel nodes were isolated. One SLN (5%) was positive for metastatic disease using H&E staining. Of the 18 negative SLNs, 2 (11%) had micrometastases (< 0.2 mm) upon serial sectioning and immunohistochemical staining.

CONCLUSION

Combined-modality mapping enhances detection of SLNs in vulvar carcinoma. Histologic microstaging improves the detection of micrometastases within SLNs.

How to avoid multiple pregnancies in assistive reproductive technologies

Since 1980, there has been a worldwide dramatic increase in multiple births. This seems to be due to an increase in the age of reproduction, the use of ovulation induction, and the use of in vitro fertilization. Scarce data suggest that each of these causes is responsible for about one-third of the problem, although quintuplets and more are almost invariably due to ovulation induction. There has been little or no effort to issue guidelines or regulations with respect to ovulation induction, but there has been much advice as to how to control the problem in in vitro fertilization by limiting the number of embryos to be transferred. In sum, a good selection of high-quality embryos on day 3 would allow a high rate of pregnancy with the transfer of one or two blastocysts. Good results of cryopreservation must be part of an agreement in an in vitro fertilization program. If singleton live birthrates were considered to be the principal outcome of assisted reproductive technologies reported by centers and registry, twin and triplet rates should also be reported separately. And finally, if financial considerations would not limit the cost of reimbursement to in vitro fertilization procedures, the number of procedures could be increased with fewer embryos transferred.

Postoperative pelvic irradiation in early stage uterine mixed mullerian tumors

PURPOSE OF INVESTIGATION

To review our management experience with uterine mixed mullerian tumors (MMTs) in order to evaluate potential prognostic indicators, and assess the efficacy of various treatment modalities.

METHODS

A retrospective, clinicopathologic evaluation of 43 patients presenting for treatment of uterine MMTs between 1982 and 1992 was conducted. Diagnostic criteria for inclusion was the presence of both a malignant glandular or squamous epithelial component, and a homologous or heterologous stromal component.

RESULTS

Overall 2- and 5-year cancer related Kaplan-Meier survival estimates with 95% confidence intervals were 44 (.28, .59) and 26% [.12, .39], respectively. Survivals were 83 [.62, .99] and 58% [.31, .85] when disease was confined to the uterus, and 22 [.03, .41] and 7% [.01, .20] when disease extended beyond the uterus. Clinical staging was often inaccurate, with 29% of clinical stage I or II disease being upstaged at laparotomy. A significant survival advantage was found in patients with stage I or II disease treated with surgery plus pelvic irradiation (p = 0.001), as compared to those treated with surgery alone. The prognosis after disease recurrence was poor, irrespective of secondary therapy, with a median survival of 11 months.

CONCLUSIONS

A therapeutic advantage may be gained from postoperative pelvic irradiation in the treatment of surgical stage I or II uterine MMT.

Impact of a cryopreservation program on the multiple pregnancy rate associated with assisted reproductive technologies

OBJECTIVE

To determine the impact of a cryopreservation program on pregnancy rates and multiple-pregnancy rates in ART cycles.

DESIGN

Retrospective study.

SETTING

University teaching hospital.

PATIENT(S)

Women who underwent stimulation for in vitro fertilization at the Jones Institute for Reproductive Medicine between October 1987 and June 1999.

INTERVENTION(S)

Analysis of pregnancy and multiple-pregnancy rates based on the number of embryos transferred.

MAIN OUTCOME MEASURE(S)

Implantation; pregnancy and multiple-pregnancy rates.

RESULT(S)

Pregnancy rates per transfer increased from 9% when one embryo was transferred to 20% with two embryos, 35% with three embryos, 40% with four embryos, and 41% with five embryos. The rate of twin pregnancies increased to 21% with two embryos, 23% with three embryos, 21% with four embryos, and 22% with five embryos. The triplet pregnancy rates were 8% with three embryos, 9% with four embryos, and 2% with five embryos. A theoretical model limiting the number of embryos transferred to two with cryopreservation and subsequent transfer yields a cumulative pregnancy rate of 77%, a twin rate of less than 20%, and no triplet or higher-order pregnancies.

CONCLUSION(S)

The use of a cryopreservation program can help maximize pregnancy rates while minimizing multiple-pregnancy rates. Cryopreservation should be considered in all assisted reproductive technology cycles.

Evaluation of the clinical efficacy of embryo cryopreservation

To fully evaluate the advantages of a cryopreservation program a method needs to be established to express the additional patients pregnant from cryopreservation. The patient specific method considers cryopreservation as augmentation only among patients without a pregnancy from the fresh transfer, or from previously transferred frozen material from the same harvest. In an analysis of the pregnancy rate at the Jones Institute between January 1996 and December 1998 we found a fresh pregnancy rate of 40.8% in the good responders and 28.8% in poor responders. The patient specific pregnancy rate in the same cycles was 53.4% in good responders and 32.3% in poor responders. Good responders less than 35 years of age with ten or more mature eggs at retrieval had a fresh pregnancy rate of 40.2% and a patient specific pregnancy rate of 57.9%. It is exceedingly important for the physician and patient to understand and comprehend the potential in cryopreserved material.

Detection of endometrial pinopodes by light microscopy

OBJECTIVE

To study the value of light microscopy (LM) in the assessment of endometrial pinopodes.

DESIGN

Comparative histologic study.

SETTING

Outpatient infertility clinic in an academic teaching institution.

PATIENT(S)

Eighteen oocyte donors undergoing controlled ovarian hyperstimulation.

INTERVENTION(S)

Endometrial biopsies on days 14-24 of the cycle.

MAIN OUTCOME MEASURE(S)

Assessment of pinopodes by scanning electron microscopy (SEM) and of endometrial surface projections by LM.

RESULT(S)

The luminal surface was identified by LM in 36 of 38 endometrial specimens obtained. Although apical projections could be recognized in all, they were few, moderate, and abundant in 20, 12, and 4 cases, respectively. Pinopodes were detected by SEM in all 4 samples with abundant projections, but in only 14 of 32 samples with lesser quantities of these surface features. No predictive value could be ascribed to apical projections viewed by LM for the developmental stage of pinopodes as defined by SEM.

CONCLUSION(S)

The LM of routine endometrial specimens can serve as a preliminary tool in the evaluation of surface morphology. Although abundant apical projections by LM are compatible with the presence of pinopodes by SEM, the latter modality remains as the definitive method in cases with few or moderate projections and for the evaluation of the stage of pinopode development.

Histochemical localization of endometrial insulin-like growth factor binding protein-1 and -3 during the luteal phase in controlled ovarian hyperstimulation cycles: a controlled study

OBJECTIVE

To determine if controlled ovarian hyperstimulation (COH) affects the endometrial expression of IGFBP-1 and IGFBP-3.

DESIGN

Prospective, controlled study.

SETTING

Tertiary infertility clinic.

PATIENT(S)

Eighteen oocyte donors undergoing COH cycles and 17 natural cycle controls.

INTERVENTION(S)

Controlled ovarian hyperstimulation, endometrial biopsies.

MAIN OUTCOME MEASURE(S)

Immunohistochemical scoring of endometrial IGFBP-1 and -3 expression, morphological endometrial dating, and serum estradiol (E(2)), LH, and progesterone (P(4)) concentrations.

RESULT(S)

No statistically significant difference was observed between natural and stimulated cycles in change in IGFBP-1 or -3 over standardized cycle days throughout the window of embryo implantation (days 17-24). The IGFBP-1 and -3 expression was zero or near zero for both the natural and COH cycles until day 12-13. Both IGFBPs showed increased production throughout the secretory phase. Advanced endometrial histology (>/=1 day) in glands and stroma was noted in COH cycles. Significant positive correlations of E(2) and P(4) were noted with IGFBP-1 and -3 but not with advanced endometrial morphology in the COH cycles.

CONCLUSION(S)

The COH cycles have no significantly increased endometrial IGFBP-1 or -3 expression throughout the implantation phase of the luteal cycle compared with normal menstrual cycles. Both IGFBPs were absent in the proliferative phase and increased throughout the secretory portion of the embryo implantation window.

Endometrial glycodelin-A expression in the luteal phase of stimulated ovarian cycles

OBJECTIVE

To determine if controlled ovarian hyperstimulation (COH) affects the endometrial expression of glycodelin-A (GdA).

DESIGN

Prospective, controlled study.

SETTING

Tertiary infertility clinic.

PATIENT(S)

Fifteen oocyte donors undergoing COH cycles and 19 natural-cycle control patients.

INTERVENTION(S)

COH, endometrial biopsies.

MAIN OUTCOME MEASURE(S)

Immunohistochemical scoring of endometrial GdA expression, morphologic endometrial dating, and serum E2, LH, and P4 concentrations.

RESULT(S)

GdA was detected in all subjects throughout the implantation window period. Immunolocalization was demonstrated in the endometrial glands and not in the stroma or on the surface. A significantly increased proportion of GdA-staining endometrial cells were noted in COH cycle patients as compared with natural-cycling control patients throughout the window of embryo implantation. Both cycle types demonstrated increasing GdA expression throughout the late luteal phase. A significant positive correlation was noted between GdA expression and serum E2 levels (r = 0.5, P<.001) in natural cycles and advanced histology in COH cycles (r = 0.63, P=.01). Neither LH nor P4 were correlated with endometrial GdA expression.

CONCLUSION(S)

COH cycles have a significantly increased endometrial GdA expression throughout the implantation phase of the luteal cycle when compared with normal menstrual cycles. The increased expression may affect implantation during COH cycles.
