ABSTRACT: To address the consequences of surgical curettage following failed medical abortion.
A retrospective case-control study was performed in a tertiary gynecologic department. The case group comprised 104 women who underwent surgical curettage following failed medical abortion; the control group included 104 women who underwent early surgically induced abortion. Clinical characteristics and surgical findings were examined. The extent of inflammation was quantified following immunohistochemical staining for cell-surface markers characteristic of T lymphocytes, B lymphocytes, and macrophages. The extent of necrosis was evaluated morphologically.
Abnormal findings during surgical curettage were significantly more prevalent among women in the case group than in the control group (10.6% versus 1.9%; P=0.019). The most frequent abnormality in the case group was the presence of intimately adherent products of conception, necessitating sharp curettage. The extent of inflammation (represented by increased numbers of T and B lymphocytes) was greater in the case group than in the control group (P=0.046 and P=0.001, respectively), as was the extent of necrosis (P<0.05).
Curettage following failed medical abortion harbors particular difficulties, which may be attributed to an inflammatory response. The long-term consequences of curettage following failed medical abortion warrant further investigation.

ABSTRACT: The purpose of this study was to assess fertility performance and obstetric outcomes after treatment of cesarean scar pregnancy.
We conducted a retrospective study in a large tertiary hospital in Israel. The study included 18 women with a diagnosis of cesarean scar pregnancy between 2000 and 2009.
The incidence of cesarean scar pregnancy among our parturient patients was 1 per 3000 for the general obstetric population and 1 per 531 among those with at least 1 cesarean delivery. Sixteen were treated primarily with methotrexate. Two were treated primarily by surgery, and 2 more were treated by surgery after failed methotrexate treatment. After cesarean scar pregnancy treatment, 7 women conceived spontaneously, and 1 conceived by in vitro fertilization-intracytoplasmic sperm injection. The remaining 10 (55%) did not wish to conceive again. Two of the women who became pregnant (25%) had recurrent cesarean scar pregnancy.
This study shows encouraging results for fertility performance and obstetric outcomes after treatment of cesarean scar pregnancy. Nevertheless, the risk of recurrent cesarean scar pregnancy is not negligible.

ABSTRACT: To present four cases of twin tubal pregnancies and discuss possible etiologies. Twin tubal pregnancies are a rare event, with incidence rates estimated as 1 out of 725-1,580 of tubal pregnancies.
Case series.
Department of obstetrics and gynecology at a tertiary health care facility.
All women with twin tubal pregnancy diagnosed and treated in the department during the years 2007-2009, according to electronic files and histologic reports.
None.
Artificial reproductive technique preceding twin tubal pregnancies
We diagnosed four twin pregnancies of 163 tubal pregnancies, an incidence of 2.4%. Of the four cases, two conceived after gonadotropin stimulation and intrauterine insemination. The third conceived following in vitro fertilization and intracytoplasmic sperm injection. The fourth was a spontaneous conception diagnosed as monochorial monoamniotic twin tubal pregnancy.
Twin tubal pregnancies may not be as rare as previously thought. Three of the four cases identified during a 2-year period followed artificial reproductive technique. We hope that this report will promote the study of the epidemiology of this event, improve diagnosis, and encourage the development of treatment modalities.

ABSTRACT: To define the preoperative independent predictors indicating that renal mass has benign histologic features.
A total of 1664 patients with Stage T1-T2N0M0 with a unilateral renal mass underwent nephrectomy. The endpoint at multivariate analysis was benign versus malignant histologic features.
The surgical approach (odds ratio [OR] 2.9, P = .0001), sex (OR 1.97, P = .0001), and age (OR 1.01, P = .007) were independent predictors for the malignant-benign distinction. Malignant tumors were more likely to occur in men (878 of 1009, 87%) versus women (515 of 651, 79%; P <.001). A weak relationship was found between an increasing tumor size and malignancy risk in men only. High-grade renal cell carcinoma was more prevalent in men (31% versus 21%, P = .001). The histologic tumor types were distributed differently between the 2 sexes: 8% papillary renal cell carcinoma in women versus 16% in men, 86% and 78% clear cell renal cell carcinoma, 33% and 57% oncocytoma, and 40% versus 12% angiomyolipoma, respectively. The physician's preoperative judgment regarding tumor amenability for nephron-sparing surgery resulted in patient selection: 10% benign tumors for radical nephrectomy versus 25% for partial nephrectomy (P = .001) and 31% versus 20% high-grade tumors, respectively (P = .0001).
Renal tumors were consistently benign in 20% of women, regardless of size. In contrast, in men, the malignancy risk increased slightly with tumor size. The surgeons' preoperative decision regarding nephron-sparing surgery caused a selection bias in favor of benign lesions, regardless of sex. Our findings support the possibility of basing treatment decisions on the preoperative biopsy findings. Such changes could alter current practice and limit treatment of histologically proven benign lesions to surveillance or ablation only.

ABSTRACT: To define the rate of positive surgical margins (PSMs) and analyze the outcome of patients with PSMs. The outcome and proper management of patients with positive PSMs during nephron sparing surgery (NSS) are questionable. In this study we define the clinical outcomes of PSMs at NSS and suggest management.
Clinical records of 114 renal units who underwent open NSS for a renal mass between May 1995 and September 2005 were reviewed.
PSMs were suspected on frozen section in 17 of 114 renal units (15%). Tumors with suspected PSMs at frozen section were smaller (2.9 +/- 1.6) in comparison to those with negative surgical margins (3.4 +/- 1.8 cm) (P = .001). Nine of 17 (53%) cases underwent total nephrectomy (5 immediately, 4 delayed). In 4 (24%), immediate re-excision of the renal crater was performed. A total of 4 (24%) that were followed up clinically were with no evidence of disease. Therefore, in 13 of 17 (77%) cases, the presence of tumor cells at the remaining side of the kidney could be evaluated histologically. In 2 cases from the immediate response group, tumor cells were found in the side opposite to the resection. There was no residual tumor in any case subjected to delayed nephrectomy. At median follow-up of 71 months, 15 of 17 patients are alive and with no evidence of disease. Two patients died because of unrelated causes. The overall 5-year survival rate is 98.2% and there is no cancer-specific mortality.
The true PSM rate is in the range of 1.75%-5.26%. No disease progression or deaths attributable to renal cell carcinoma were associated with PSMs. Total nephrectomy should be avoided as a response to PSMs.

ABSTRACT: Pelvic splenosis is a post-traumatic spleen autotransplantation, which can mimic various gynaecological diseases. A case of a 39-year-old woman, who underwent partial splenectomy because of a road accident in her childhood, currently presenting with abdominal pain and suspected corpus luteus torsion. Diagnostic laparoscopy was conducted which ruled out twisted ovary. This confirmed disseminated pelvic splenosis as a coincidental finding. Following this procedure, the abdominal pain ceased. The current report aims to raise the awareness of splenosis so that it may be appropriately recognized and differentiated from other pelvic findings.

ABSTRACT: To assess fetal abnormalities and events leading to third-trimester abortion.
The study population included all parturient women with singleton pregnancy that underwent termination of pregnancy (TOP) in the third trimester in our institute because of fetal indications between 1998 and 2006.
There were 777 cases of TOP due to fetal anomalies in our center during the study period, and 52 terminations were carried out in the third trimester. All cases of third-trimester abortions were due to severe malformations with high probability of perinatal death or severe handicap: 65.3% anomalies were structural, and 58.9% of them involved the central nervous system (CNS). Genetic indications included mostly genetic diseases, unlike aneupluidities in earlier terminations. Routine prenatal care raised suspicion of abnormalities in 22 (42.3%) cases, and diagnosis was established by additional tests. Abnormal findings were either missed in 4 (7.7%) cases or developed later in 11 (21.1%) cases. No routine prenatal screening was performed in the remaining 15 (28.8%) cases.
Third-trimester abortion may be obviated by timely screening and scanning in some cases. The possibility of late TOP should be considered in malformations occurring late in pregnancy and in cases that require meticulous evaluation and follow-up from earlier stages of gestation.

ABSTRACT: To present prenatal findings and maternal and neonatal outcomes following second- and early third-trimester spontaneous antepartum uterine rupture events in our institute.
Charts of patients with full-thickness second- or early third-trimester symptomatic uterine ruptures locally treated between 1984 and 2007 were evaluated.
There were seven events involving six women, all requiring emergency laparotomy, and cesarean section (CS). During the study period in our institute, there were 120 636 singleton deliveries (> or =22 weeks' gestation), including 5 of our cases, while in 2 cases, the rupture occurred earlier (<22 weeks' gestation). The rupture occurred after > or = 1 previous CSs in five cases. Six events were associated with abnormal placentation: placenta previa (n = 3), placenta percreta (n = 1), or both (n = 2). Other associated events included short, interpregnancy (IP) interval (n = 3) and past uterine rupture (n = 2). Pregnant women at gestational age > or = 22 weeks, who had the combination of placenta previa, and previous CS (n = 3), had a higher chance for spontaneous symptomatic antepartum uterine rupture when compared to women with placenta previa without a previous CS (OR 29.3, 95% CI 1.5-569.3, p = 0.007). There were no maternal deaths. Three of the five viable neonates survived.
Spontaneous symptomatic second- or early third-trimester uterine rupture in nonlaboring women is a very rare, obstetric emergency, which is hard to diagnose. Maternal and neonatal outcomes can be optimized by awareness of risk factors, recognition of clinical signs and symptoms, and availability of ultrasound to assist in establishing diagnosis, and enabling prompt surgical intervention.

ABSTRACT: To supplement existing cases of cesarean scar pregnancy presenting as acute conditions. All of the study women had been treated by a conservative surgical approach.
Retrospective study.
Department of obstetrics/gynecology of a tertiary referral center.
We identified six pregnant women at 7-15 weeks' gestation who underwent emergency laparotomy and uterine-preserving surgery. Four of them were initially treated by uterine curettage because of misdiagnosed intrauterine pregnancies. The other two experienced failed methotrexate treatment.
All patients underwent a similar surgical technique while actively bleeding. This included laparotomy and ligation of bilateral uterine arteries, followed by wedge resection of the entire pregnancy in scar. The uterus was sutured in two layers.
All the reported women in our series had been cured and their uteruses have been preserved.
There was an inadvertent injury to the bladder in one case, which was immediately repaired, and blood transfusion was required in two other cases. The postoperative course was uneventful for all the patients. One of the patients has already spontaneously conceived and she had an ongoing normal pregnancy at the time of writing.
This small case series emphasizes that uterine-preserving surgery is an optional management for cesarean scar pregnancies presenting as acute conditions, cases resistant to medical treatment, or for women at advanced gestation.

ABSTRACT: We examined the prevalence of malignancy in a synchronous ipsilateral renal lesion identified during partial nephrectomy and evaluated its clinical significance.
We retrospectively reviewed the records of 112 patients (114 renal units) who underwent nephron sparing surgery for a clinically localized sporadic renal mass between May 1995 and September 2005.
In 37 patients (32%) an additional lesion was diagnosed and excised intraoperatively, while in 67% these lesions were known before the operation and believed to be simple cysts. During surgery the additional mass was suspicious in 8 cases and in the remainder the mass was described as simple cysts that were excised. The mean size of the primary mass was 3.1 cm (SD 1.4). In 29 (78%) cases the primary mass was malignant, in 23 (79%) of these the second mass was benign and in the remainder renal cell carcinoma was diagnosed. In 8 cases (22%) the primary mass was benign and in 2 (25%) the secondary mass was malignant. Overall 22% of all second masses were malignant, and all were low grade and low stage. We found that 7% of second ipsilateral masses could be expected to harbor malignancy.
Based on our data it is questionable whether total nephrectomy is mandatory as an immediate response to an ipsilateral synchronous second renal mass. The present findings may represent an increased appreciation of ipsilateral multicentricity compared to historical data.

ABSTRACT: Infections caused by Aspergillus species are increasing in importance, especially among immunocompromised hosts. The objective of this study was to evaluate the efficacy of combination treatment consisting of the polyene amphotericin B (AMB) or amphotericin B-intralipid admixture (AMB-IL) and the echinocandin caspofungin (CAS) in experimental murine systemic aspergillosis. Inhibition of synthesis of a major component of the fungal cell wall and an effect on the cell membrane, by combining echinocandin and a polyene, may result in a synergistic interaction in vitro and in vivo against Aspergillus fumigatus.
ICR mice were immunosuppressed by intraperitoneal (ip) administration of cyclophosphamide (CY). Three days post-CY administration the mice were inoculated intravenously (iv) with A. fumigatus conidia. Infection and treatment were evaluated during an observation period of 30 days in terms of mortality (survival rate and mean survival time) and morbidity (quantitative determination of fungal burden, histopathology, and detection of serum galactomannan).
The data showed that combined CAS and AMB or AMB-IL treatment increased the survival of the mice (up to 69.2%) as compared to those treated with each agent alone (44.4, 40.7 and 50%, respectively), and prolonged their mean survival time to 22.5 days. These combinations also resulted in reduction of fungal burden in organs, and decrease in serum galactomannan.
The successful results obtained in the experimental animal model of this study may possibly open the way to more effective management of aspergillosis in humans.

ABSTRACT: In an attempt to determine if it is possible to distinguish hamartoma of the breast from fibroadenoma using fine-needle aspiration cytology, we reviewed the cytological slides of 13 histopathologically confirmed cases of hamartoma of the breast and compared them with the cytological features of 13 histologically confirmed fibroadenomas. In each case, we studied the epithelial and stromal features. Cytologic characteristics were retrospectively evaluated in a semiquantitative manner. In conclusion, the finding of intact lobular units and a relative paucity of stroma may suggest the diagnosis of hamartoma.

ABSTRACT: In view of the poor therapy outcomes of invasive aspergillosis, the objective of this study was to evaluate the efficacy of combination treatment consisting of the polyene amphotericin-B-intralipid, the echinocandin caspofungin and granulocyte-colony stimulating factor (G-CSF) in experimental murine systemic aspergillosis. With inhibition of synthesis of 1,3-beta-d-glucan in the fungal cell wall by caspofungin and an effect on the cell membrane by amphotericin-B-intralipid, this treatment may result in a synergic effect against Aspergillus fumigatus. Addition of G-CSF may further contribute to therapy of aspergillosis.
ICR mice were immunosuppressed by intraperitoneal administration of cyclophosphamide. Three days later, the mice were inoculated intravenously (iv) with A. fumigatus conidia. Infection and treatment were evaluated during an observation period of 30 days in terms of mortality (survival rate and mean survival time) and morbidity (quantitative determination of fungal burden, histopathology, and detection of serum galactomannan).
Combination of caspofungin + G-CSF or addition of G-CSF to the combination of caspofungin + amphotericin-B-intralipid increased the survival rate of infected mice up to 78.9% and prolonged their mean survival time to 25 days. These combinations also resulted in a reduction in fungal burden in organs, and a decrease in serum galactomannan.
The successful results obtained in the experimental model may possibly open the way to more effective management of aspergillosis in humans.

ABSTRACT: Breast hamartoma is an unusual, well-circumscribed, tumor-like mass entering into the differential diagnosis of benign breast disease. To the authors' knowledge, the cytology of these lesions has not been well described. Although fine-needle aspiration is a well established procedure for the detection of breast carcinoma, its utility in classifying benign breast disease is less clear.
Fine-needle aspirates from eight patients with histologically proven hamartomas were reviewed. None of the cases had a preoperative fine-needle aspiration diagnosis of hamartoma. Cytologic characteristics were retrospectively evaluated in a semiquantitative manner and compared with the histologic findings.
The aspirates were moderately cellular and contained sheets of both bland ductal cells and lobular units. Adipose tissue was present in varying amounts. Bipolar stromal nuclei were readily apparent, whereas intact stromal fragments were less prominent. Cytologic atypia was uniformly absent.
The cytology of breast hamartomas shows considerable overlap with other benign breast disease and is unlikely to be interpreted as malignant. The findings of intact lobular units and a relative paucity of stroma in an aspirate from a well circumscribed breast lesion may suggest the diagnosis of hamartoma.
