Dydrogesterone in the reduction of recurrent spontaneous abortion

One hundred and eighty Women with a history of recurrent, unexplained spontaneous abortion (mean 3.5 abortions) were randomised to receive oral dydrogesterone (10 mg b.i.d.), intramuscular human chorionic gonadotrophin (hCG; 5000 IU every 4 days) or no additional treatment (controls). Treatment was started as soon as possible after confirmation of pregnancy and continued until the 12th gestational week. All women received standard supportive care. Abortions were significantly (p ≤ 0.05) less common in the dydrogesterone group (13.4%) than in the control group (29%); there were no statistically significant differences between the hCG group and the control group. There were no differences between the groups with respect to pregnancy complications or congenital abnormalities. In conclusion, hormonal support with dydrogesterone can increase the chances of a successful pregnancy in women with a history of recurrent spontaneous abortion.     

Vertical mammaplasty: early complications after 250 personal consecutive cases.

No surgeon likes to face complications. It takes effort to treat them personally and more effort to note, count, analyze, and demonstrate them. The author carefully followed 250 personal consecutive patients (476 breasts) who underwent vertical mammaplasties between 1990 and 1998; studying the complications and their relationship with the types of breasts and patients was very instructive. The main observations from this study follow. The most frequent benign complication was seroma (5 percent of breasts), which usually required one or two aspirations after surgery. Hematomas occurred in six patients (1.2 percent of breasts), who had all had mastopexies. Hematomas required immediate surgical evacuation. The major complication of breast reduction, i.e., areola necrosis, was rare (only two partial necroses occurred), but it left deformities that were difficult to correct. Infection without tissue necrosis was rare (two cases), and healing complications happened in only 5.4 percent of all cases. Healing complications were directly related to the size and fat content of the breasts. None occurred in mastopexy cases. For reductions, delayed skin healing was observed in 5 percent of cases and delayed breast tissue healing in 3 percent of cases. More healing complications occurred after liposuction of the breast, which was performed in the more fatty breasts. Delayed healing of skin and breast tissue was bothersome because healing was slow, but it left only a moderate deformity. In cases of delayed healing, frequent dressings, rinsing the wound with antiseptic solutions, giving antibiotics if needed, and refraining from early surgical intervention are the keys to success. Good personal contact with the patient, especially if healing is slow, is the best way of helping her and avoiding aggressive attitudes. In conclusion, this survey revealed few complications; however, it does show that the risk of delayed and slow healing is greater in larger breasts. In obese patients, a simpler operation may be indicated, such as liposuction with skin reduction alone or a free nipple graft, as long as the patient is not motivated to obtain the best possible result.     

Oral dydrogesterone versus intravaginal micronised progesterone as luteal phase support in assisted reproductive technology (ART) cycles: results of a randomised study

The objective of this prospective, randomised study was to compare the efficacy, safety and tolerability of vaginal micronised progesterone with oral dydrogesterone as luteal phase support after in-vitro fertilisation (IVF). A total of 430 women underwent IVF/intracytoplasmic sperm injection (ICSI) treatment. Long protocol gonadotropin releasing hormone analogue down-regulation was followed by gonadotropin stimulation. Human chorionic gonadotropin was given when two or more follicles reached ≥17 mm. After 36 h, oocytes were retrieved and IVF was performed. Embryo transfer was done at the 4–8 cell embryo stage. Luteal support was initiated from the day of embryo transfer and continued for up to 14 days. Patients were randomised to luteal supplementation with either intravaginal micronised progesterone 200 mg three times daily (n = 351) or oral dydrogesterone 10 mg twice daily (n = 79). In cases of a positive pregnancy test, luteal support was continued for 12 weeks. Both dydrogesterone and micronised progesterone were associated with similar rates of successful pregnancies. Vaginal discharge or irritation were reported by 10.5% of patients given micronised progesterone. Significantly (p < 0.05), more patients given dydrogesterone than micronised progesterone were satisfied with the tolerability of their treatment. There were no differences between the treatments with regard to liver function tests.     

Breast volume and anthropomorphic measurements: normal values

Fifty-five consecutive female volunteers were evaluated. Linear measurements of the breast and nipple position were determined to fixed points on the chest wall. Volume determination was done by a standard chest-wall casting technique. A highly significant difference was found between left and right breasts in the axilla-to-nipple distance and nipple-to-midline measurements. A significant difference was also found in the distance from the lowest point of the breast (patient upright) to the nipple. Analysis of the volumetric difference between right and left breasts did not achieve statistical significance.     

Delayed-immediate breast reconstruction

In patients with early-stage breast cancer who are scheduled to undergo mastectomy and desire breast reconstruction, the optimal timing of reconstruction depends on whether postmastectomy radiation therapy will be needed. Immediate reconstruction offers the best aesthetic outcomes if postmastectomy radiation therapy is not needed, but if postmastectomy radiation therapy is required, delayed reconstruction is preferable to avoid potential aesthetic and radiation-delivery problems. Unfortunately, the need for postmastectomy radiation therapy cannot be reliably determined until review of the permanent tissue sections. The authors recently implemented a two-stage approach, delayed-immediate breast reconstruction, to optimize reconstruction in patients at risk for requiring postmastectomy radiation therapy when the need for postmastectomy radiation therapy is not known at the time of mastectomy. Stage 1 consists of skin-sparing mastectomy with insertion of a completely filled textured saline tissue expander. After review of permanent sections, patients who did not require post-mastectomy radiation therapy underwent immediate reconstruction (stage 2) and patients who required postmastectomy radiation therapy completed postmastectomy radiation therapy and then underwent standard delayed reconstruction. In this study, the feasibility and outcomes of this approach were reviewed. Fourteen patients were treated with delayed-immediate reconstruction between May of 2002 and June of 2003. Twelve patients had unilateral reconstruction and two patients had bilateral reconstruction, for a total of 16 treated breasts. All patients completed stage 1. Tissue expanders were inserted subpectorally in 15 breasts and subcutaneously in one breast. The mean intraoperative expander fill volume was 475 cc (range, 250 to 750 cc). Three patients required postmastectomy radiation therapy and underwent delayed reconstruction. Eleven patients did not require postmastectomy radiation therapy. Nine patients had 11 breast reconstructions (stage 2), six with free transverse rectus abdominis musculocutaneous (TRAM) flaps, one with a superior gluteal artery perforator flap, and four with a latissimus dorsi flap plus an implant. The median interval between stages was 13 days (range, 11 to 22 days). Two patients who did not require postmastectomy radiation therapy have not yet had stage 2 reconstruction, one because she wished to delay reconstruction and the other because she required additional tissue expansion before permanent implant placement. Six complications occurred. The stage 1 complications involved two cases of mastectomy skin necrosis in patients who required post-mastectomy radiation therapy; one patient required removal of the subcutaneously placed expander before postmastectomy radiation therapy and the other patient had a subpectorally placed expander that only required local wound care. The stage 2 complications were a recipient-site seroma in a patient with a latissimus dorsi flap, a recipient-site hematoma in the patient with the superior gluteal artery perforator flap, and two arterial thromboses in patients with TRAM flaps. Both TRAM flaps were salvaged. Delayed-immediate reconstruction is technically feasible and safe in patients with early-stage breast cancer who may require postmastectomy radiation therapy. With this approach, patients who do not require postmastectomy radiation therapy can achieve aesthetic outcomes essentially the same as those with immediate reconstruction, and patients who require postmastectomy radiation therapy can avoid the aesthetic and radiation-delivery problems that can occur after an immediate breast reconstruction.     

Breast form changes resulting from a certain brassière

Eleven adult female subjects aged 22-39 years wore a certain brassière for 3 months while anthropometry and moiré fringe photographs on the anterior trunk were taken regularly once a week. After the 3 months, the brassière was not worn for another 3 months. Then the measurements and photogrammetry were repeated for comparison using superimposed moiré configurations. The results are summarized as follows. Regardless of slim or obese trunk, subjects with pendent breasts showed the highest degree of breast form "correction" from wearing the brassière. In all subjects, after 3 months of brassière constraint, the underbust circumference was smaller but the chest circumference became enlarged, the distance between the right and left nipples became wider, and the breasts tended to hang down. This change was more marked in obese subjects with pendent breasts. And when this type of subject wore a "well-fitted" brassière for a long time, her breast form became developed; that is, her breasts hung down more.     

Evidence That Breast Tissue Stiffness Is Associated with Risk of Breast Cancer

Background

Evidence from animal models shows that tissue stiffness increases the invasion and progression of cancers, including mammary cancer. We here use measurements of the volume and the projected area of the compressed breast during mammography to derive estimates of breast tissue stiffness and examine the relationship of stiffness to risk of breast cancer.

Methods

Mammograms were used to measure the volume and projected areas of total and radiologically dense breast tissue in the unaffected breasts of 362 women with newly diagnosed breast cancer (cases) and 656 women of the same age who did not have breast cancer (controls). Measures of breast tissue volume and the projected area of the compressed breast during mammography were used to calculate the deformation of the breast during compression and, with the recorded compression force, to estimate the stiffness of breast tissue. Stiffness was compared in cases and controls, and associations with breast cancer risk examined after adjustment for other risk factors.

Results

After adjustment for percent mammographic density by area measurements, and other risk factors, our estimate of breast tissue stiffness was significantly associated with breast cancer (odds ratio = 1.21, 95% confidence interval = 1.03, 1.43, p = 0.02) and improved breast cancer risk prediction in models with percent mammographic density, by both area and volume measurements.

Conclusion

An estimate of breast tissue stiffness was associated with breast cancer risk and improved risk prediction based on mammographic measures and other risk factors. Stiffness may provide an additional mechanism by which breast tissue composition is associated with risk of breast cancer and merits examination using more direct methods of measurement.     

Dydrogesterone in threatened abortion: pregnancy outcome

OBJECTIVE: To determine whether therapy with dydrogesterone in threatened abortion during the first trimester of pregnancy will improve pregnancy outcome. DESIGN: Prospective open study. SUBJECTS: Pregnant women presenting to the obstetric and gynaecology clinic admitting center with vaginal bleeding before 13 weeks gestation were evaluated for entry into the study. Women were excluded if they had a history of recurrent miscarriage. METHOD: Eligible subjects were randomized to receive either dydrogesterone 40 mg stat dose followed by 10 mg twice a day for one week or conservative therapy. RESULTS: One hundred and 54 women were recruited. There was no statistically significant differences between the two groups with regard to pre-treatment status. The continuing pregnancy success rate was significantly (p=0.037) higher in women treated with dydrogesterone (95.9%) compared with women who received conservative treatment (86.3%). The odds ratio of the success rate between dydrogesterone treatment and non-treatment was 3.773 (95% confidence interval: 1.009-14.108). CONCLUSION: Corpus luteal support with dydrogesterone has been shown to reduce the incidence of pregnancy loss in threatened abortion during the first trimester in women without a history of recurrent abortion.     

Immediate breast reconstruction using biodimensional anatomical permanent expander implants: a prospective analysis of outcome and patient satisfaction

Immediate breast reconstruction is offered to the majority of women requiring a mastectomy for cancer treatment. Improvements in implant technology have seen the evolution of shaped, fixed-volume implants and permanent expanders. The theoretical benefits of biodimensional anatomical expander implants include better reconstructed breast form, the potential for achieving this at a single procedure, and the avoidance of a contralateral procedure as a result of improved ipsilateral cosmesis. The aim of the present study was to assess outcome after immediate breast reconstruction using the McGhan 150 permanent expander implant. A total of 107 consecutive patients (129 breast reconstructions) were studied over a 30-month period; 49 patients (68 reconstructions) had submuscular implant placement alone, and 58 patients (61 reconstructions) had an implant in conjunction with a latissimus dorsi flap. The mean patient age was 47 years (range, 22 to 72 years) and the mean follow-up was 18 months (range, 6 to 40 months). Outcome was assessed in the following four ways: geometric measurements, evaluation of photographs by four independent observers, linear numerical analogue scale, and a quality-of-life questionnaire. Geometric measurements after surgery showed median differences that were highly consistent with good symmetry. Transverse breast width difference between breasts was 0.35 cm, vertical breast height difference was 0.8 cm, sternal notch-to-nipple distance difference was 0.6 cm, midclavicular line-to-nipple distance difference was 0.5 cm, nipple-to-inframammary crease distance difference was 0.5 cm, midline-to-nipple distance difference was 0 cm, and projection difference was 0 cm. Photographic assessment by four observers who evaluated shape, cleavage, symmetry, and overall outcome produced correlation values of 0.73 to 0.81. More than 75 percent of each of these parameters was scored as good or excellent. A numerical analogue scale (from 1 to 10) assessing overall result by the surgeon and patient revealed good (7 to 8) or excellent (9 to 10) scores in 83 and 82 percent of respondents, respectively. Quality-of-life data showed that 81 and 88 percent of women felt "a little" or "not at all" less feminine, respectively, and 88 percent were satisfied with the appearance of their breasts. A total of 88 percent of women would also choose the same reconstructive procedure if faced with the same cancer diagnosis. Complication rates were low; infections occurred in 6.2 percent of reconstructions, hematoma occurred in 1.6 percent, and implant loss occurred in 3.9 percent. Only 24 of 107 patients (22 percent) elected to have a synchronous contralateral breast adjustment, and four of 107 (4 percent) chose to have a subsequent procedure for symmetry. Biodimensional expander implants used in immediate breast reconstruction are associated with high levels of patient and surgeon satisfaction. Optimum breast form can be achieved during a single operation with a low incidence of complications.     

A comparison of outcomes using three different methods of breast reconstruction.

In a review of 325 postmastectomy breast reconstructions, the aesthetic quality of the result and the risk of unsuccessful outcome were compared for three techniques: tissue expansion (105 breasts), latissimus dorsi myocutaneous flap (47 breasts), and TRAM flap (173 breasts). The aesthetic successes achievable with the three methods were similar, and some excellent results were achieved with each of them. The failure rate after tissue expansion (21 percent) was significantly higher than those observed with the TRAM (3 percent) and latissimus (9 percent) flaps. Tissue expansion also was not as aesthetically successful as other techniques in obese patients. For immediate breast reconstruction, the TRAM flap was the most aesthetically successful technique. Although tissue expansion has advantages and may be the best choice for some patients, methods that used autogenous tissue provided more consistent success.     

Reliability of inferior pedicle reduction mammaplasty in burned oversized breasts

Heavy pendulous breasts cause physical and psychological trauma. Postburn deformity of breasts results in significant asymmetry, displacement of nipple-areola complex, due to burn scar contracture, and significant scarring; these factors add more psychological discomfort and subsequent behavioral changes. The use of the inferior pedicle procedure in burned breasts can solve many problems. The technique reduces the size of the large breast, eliminates the scar tissue by excising both medial and lateral flaps, and brings the mal-located nipple and areola to a normal position. This study stresses the possibility of harvesting the inferior dermal pedicle flap from within the postburn scar tissue without necrosis of the nipple and areola, because of the excellent flap circulation. Acceptable aesthetic appearance and retainment of nipple viability and sensitivity can be achieved with the inferior pedicle technique even with postburn deformity of the breast. The study was conducted on 11 women, all of whom had sustained deep thermal burns to the breasts and anterior torso and whose breasts were hypertrophied and pendulous.     

Autogenous augmentation mammaplasty with microsurgical tissue transfer

Many patients dream of reducing their abdominal or gluteal fat tissue and, in the same procedure, enlarging their breasts without the need for implants and their related problems. Following this demand, a new "natural" alternative to breast augmentation with autogenous tissue is presented. Since 1993, 16 patients have undergone either unilateral or bilateral breast augmentation with free fat transfer. These 20 augmentation mammaplasties consisted of nine deep inferior epigastric perforator flaps, eight superior gluteal artery perforator flaps, and three superficial inferior epigastric artery flaps. The postoperative results were judged aesthetically by independent examiners and by the patients according to Netscher's score. The additional operations for final shaping of the breasts and the postoperative complications at the donor and recipient sites are reported. The augmented breasts improved the aesthetic proportions more than 100 percent. All flaps survived, and except for minor postoperative complications such as small areas of wound dehiscence, the breasts could be shaped aesthetically in a second-stage procedure several weeks later. Breast augmentation with autogenous tissue offers a natural alternative to alloplastic augmentation mammaplasty.     

Treatment with a single vaginal suppository containing 15-methyl PGF2 alpha methyl ester at expected time of menstruation.

Termination of early pregnancy, by vaginal administration of prostaglandin analogues, one to three weeks after the first missed menstrual period, has advantages and disadvantages in comparison with vacuum aspiration. Some of these may be reduced if the patient is treated earlier. In the present study the effect and safety of one vaginal administration of 2.5 to 3 mg 15-methyl-PGF2 alpha methyl ester around the expected time of menstruation was evaluated in 16 women exposed to the risk of pregnancy. The overall number of treatment cycles was 35 and pregnancy was confirmed by plasma beta-HCG in eight. The treatment resulted in bleeding in all the pregnant cycles while in the nonpregnant ones it only provoked spotting and bleeding did not begin until the expected time of menstruation. Treatment with 2.5 mg 15-methyl-PGF2 alpha methyl ester resulted in complete abortion in one of three women. If the dose was increased to 3 mg all five treated women aborted. In nonpregnant patients no changes in the levels of estradiol-17 beta or progesterone at any time during the 24-hour observation period were found. Serum cortisol and prolactin but not TSH levels started to increase two hours after the start of treatment and reached a maximum after five hours. The increase coincided with the onset of uterine pain. Ovulatory cycles as judged from basal body temperature occurred in the first menstrual cycle following treatment in all nonpregnant patients. Although possible to use as a "once a month treatment" it seems preferable since the dose is the same, to postpone treatment until menstruation is delayed for a week or more.     

Repeat reduction mammaplasty

Repeat reduction mammaplasty is an uncommonly performed procedure. Currently, no clear operative guidelines of management exist. Sixteen patients (28 breasts) with a mean age of 29 years (range, 13 to 52 years) underwent repeat breast reduction over an 11-year period. Before the first reduction, the mean notch to nipple distance was 29.6 cm (range, 24 to 38 cm) and mean nipple to inframammary crease distance was 15.5 cm (range, 12 to 18 cm). The mean mass of tissue excised was 615 g per breast. A number of different pedicles were used (six inferior, five superior, four superomedial, one unknown). All patients subsequently developed pseudoptosis. The nipple to inframammary crease distance was a mean of 11.4 cm (having initially been set at 7 cm) before the second procedure. At the second operation, two patients (three breasts) had their initial pedicles transected and the nipple-areola complex moved, and both patients developed vascular compromise of the nipple-areola complex (two breasts). Where the same pedicle was used in the second operation (five patients, 10 breasts), one patient developed unilateral nipple-areola complex necrosis. In eight patients, because of the development of pseudoptosis, the nipple was in a satisfactory position, and therefore only an inferior wedge of tissue required excision. This was performed without nipple-areola complex compromise, irrespective of the initial pedicle. The mean mass of tissue excised in the second operation was 325 g per breast (range, 120 to 620 g). Fourteen patients were available for follow-up after a mean of 5.1 years (range, 3 months to 11.7 years) following the repeat reduction mammaplasty. In the repeat breast reduction, where nipple-areola complex transposition is planned, the initial pedicle should be reused to maintain nipple-areola complex perfusion. Where the initial pedicle is not known, a free nipple graft may be the safest option. In patients with pseudoptosis, in whom the nipple does not require transposition, an inferior wedge of tissue can be safely excised, irrespective of the initial pedicle.     

Fat necrosis in free transverse rectus abdominis myocutaneous and deep inferior epigastric perforator flaps

A series of 310 breasts reconstructed by a single surgeon using free transverse rectus abdominis myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flaps was reviewed to see if there were any differences in the incidence of fat necrosis and/or partial flap loss between the two techniques. During the study period, 279 breasts were reconstructed with free TRAM flaps and 31 breasts were reconstructed with DIEP flaps. In the breasts reconstructed with free TRAM flaps, the incidence of partial flap loss was 2.2 percent and the incidence of fat necrosis was 12.9 percent. The DIEP flaps were divided into two groups. For the first eight flaps, patients were selected using the same criteria normally used to choose patients for free TRAM flaps. In this unselected early group, the incidence of partial flap loss was 37.5 percent and the incidence of fat necrosis was 62.5 percent. Because of the high incidence of partial flap loss and fat necrosis in the first eight flaps, subsequent selection was modified to limit the use of DIEP flaps to patients who had at least one sufficiently large perforator in each flap (a palpable pulse and a vein at least 1 mm in diameter) and who did not require more than 70 percent of the flap to create a breast of adequate size. In this later (selected) group, fat necrosis (17.4 percent) and partial flap loss (8.7 percent) were reduced to a level only moderately higher than that found in the free TRAM flap group. From these data, it can be concluded that the incidence of partial flap loss and fat necrosis is higher in DIEP flaps than in free TRAM flaps, probably because the blood flow to the former flap is less robust. This difficulty can be circumvented to some extent, however, by careful patient selection. Factors that should be considered include tobacco use, size of the perforators (especially the vein), and (in unilateral reconstructions) the amount of flap tissue across the midline needed to create an adequately sized breast. If these factors are properly considered when planning the operation, fat necrosis and partial flap loss can be reduced to an acceptable level. For selected patients, the DIEP flap is an excellent technique that can obtain a successful, autologous tissue breast reconstruction with minimal donor-site morbidity. For patients who are not good candidates for reconstruction with this flap, the free TRAM flap remains a good alternative.     

Reduction mammaplasty in postburn breasts.

Thermal injury to the anterior chest in the adolescent girl can lead to severe disfigurement of the breasts. Just as in certain non-burn female patients, mammary hyperplasia can occur in patients with previous full-thickness burns of their breasts. Most plastic surgeons have been reluctant to perform reduction mammaplasty in these patients for fear of devascularizing the skin graft or the nipple-areola complex. A series of six patients with full-thickness burns of the breasts and subsequent skin graft coverage before reduction mammaplasty is reported. Four patients had bilaterally burned breasts requiring reduction. Two patients had one burned breast reduced, and one required a balancing procedure on the unburned side. Reduction mammaplasty was performed using the inferior-pedicle technique. The mean amount of tissue removed for the left and right breasts was 454 and 395 g, respectively. There was no nipple loss, hematoma, infection, or major loss of skin flaps. Reduction mammaplasty in this group of patients is safe and carries minimal risk if certain key concepts are followed carefully.     

Capsular contracture around saline-filled fine textured and smooth mammary implants: a prospective 7.5-year follow-up.

In a previous prospective randomized clinical study comparing in the same patient textured and smooth saline-filled mammary implants (Biocell) with large pore size (300 to 600 microm), we saw no difference in capsular contracture. This study was undertaken in a similar way to compare capsular contracture around smooth and textured saline-filled prostheses with pores of small size. During a period of 7.5 years, the breast hardness was followed up, and at the end of the study patient satisfaction was evaluated.Twenty healthy women with a mean age of 30 years were operated on for breast augmentation. Two surgeons performed all operations in a standardized way. Each patient received subglandularly a Siltex textured saline-filled prosthesis with a pore size of 30 to 70 microm in one breast, and a smooth saline-filled prosthesis in the other. The hardness of the breasts was evaluated after 0.5, 1, and 7.5 years using Baker grading and applanation tonometry. Eighteen patients completed 1-year and 7.5-year follow-up. Two breasts with smooth prostheses were contracted after 6 months (Baker III or IV). After 1 year, four patients with smooth prostheses and one with a textured prosthesis had capsular contracture (p = 0.34). Seven and one-half years after surgery, six patents with smooth and four with textured implants had contracture (p = 0.66). On two patients with smooth prostheses and one patient with a textured prosthesis, the capsule around the implant hardened between 6 and 12 months. Between 1 year and 7.5 years, three breasts with smooth and textured implants contracted and one with a textured implant softened.The patients reported on a Visual Analogue Scale (1 to 10) the impact of the augmentation on their quality of life to be 9 +/- 1. Four patients preferred the breast with the smooth prosthesis, three preferred the breast with the textured prosthesis, and the others found both breasts equal. This study showed no significant difference of contracture with smooth versus fine textured implants. The majority of the patients preferred the smooth implants. The patients reported that the breast augmentation had had an extremely high impact on their quality of life.     

Short scar periareolar inferior pedicle reduction (SPAIR) mammaplasty

A method of breast reduction is presented that maintains the blood supply and innervation to the nipple and areola complex by means of an inferior pedicle, reduces the breast volume by removing tissue from the periphery of the breast, maintains breast shape with internal plication sutures, and limits the scar using a periareolar technique with a short inferior vertical-to-oblique extension. There were 167 breasts in 98 patients reduced in this fashion. The average resection volume was 632 g per breast, with an average follow-up of 7.6 months. The complication rate was similar to that observed using traditional inferior pedicle techniques with the inverted-T cutaneous scar. This technique has proven to be versatile, technically straightforward, and applicable to breasts of all sizes for both breast reduction and mastopexy. By combining the aesthetic advantage of less cutaneous scarring with the safety and familiarity of the inferiorly based pedicle, superior results in breast reduction can be obtained that are consistent, long-lasting, and satisfying for both patient and surgeon alike.     

Management of first trimester breast enlargement with necrosis.

We describe our management of two patients who had massive breast enlargement with necrosis in the first trimester. First, a therapeutic abortion was done to stop the breast growth, then we skin grafted the large ulcerated areas on the breasts, and finally we did a simple mastectomy with silicone gel implants for reconstruction. The latter procedure was to prevent almost certain recurrence of the problem during any succeeding pregnancy.     

Replacement of progesterone restores the nocturnal surge of prolactin following suppression with a gonadotropin-releasing hormone agonist during early pregnancy in the rat

Continuous administration of a GnRH agonist (GnRH-Ag) at a dose of 5 micrograms/day, commencing on day 7 of pregnancy resulted in the suppression of daily nocturnal surges of prolactin (PRL) on day 8, and serum progesterone (P4) levels with subsequent termination of pregnancy. Replacement with dydrogesterone, a synthetic analog of P4 at a dose of 4 mg/day s.c. restored the magnitude of nocturnal PRL surges. These data suggest that GnRH-Ag may act either at the level of the brain to suppress the nocturnal PRL surge, resulting in a fall in serum P4 levels or at the level of the corpus luteum itself or at both sites simultaneously to terminate pregnancy.
