The role of partial sigmoid colectomy for debulking epithelial ovarian carcinoma

Forty women underwent partial sigmoid colectomy during cytoreductive surgery for advanced epithelial ovarian carcinoma. Twenty-one (53%) and nineteen (47%) received this as part of primary or secondary debulking procedures, respectively. Fifty-four percent had postoperative residual disease less than 1 cm in largest diameter. Even though multiple surgical procedures were performed in conjunction with sigmoid colectomy, 75% of the patients had no significant postoperative morbidity. Postoperative mortality was 2.5%. Seventy-eight percent avoided permanent colostomy. Despite the above morbidity rate and aggressive postoperative therapy, the median survival for the entire group was only 14.5 months, with no significant differences between groups of patients who were categorized by primary or secondary debulking, histologic grade, amount of preoperative disease, ascites, or extent of postoperative residual disease. Although a partial sigmoid colectomy can be performed with a reasonable morbidity rate as part of debulking for ovarian cancer, and probably provides significant palliation of symptoms from large pelvic tumors, it must be used judiciously in selected patients.     

Short gracilis myocutaneous flaps for vulvovaginal reconstruction after radical pelvic surgery

The short gracilis myocutaneous flap derives its blood supply from terminal branches of the obturator artery, and the vascular pedicle derived from the medial femoral circumflex artery is sacrificed. Twenty-one short gracilis myocutaneous flaps were used for vulvovaginal reconstructions in 11 patients undergoing radical pelvic surgery: bilateral flaps in nine patients for neovaginal construction after pelvic exenterations, bilateral flaps in one patient for vulvovaginal reconstruction after radical vulvovaginectomy, and a unilateral flap in one patient for vulvovaginal reconstruction after radical vulvectomy with partial vaginectomy. Major complications consisted of bilateral flap necrosis occurring in one patient who had received preoperative irradiation to the vulva and groin combined with chemotherapy. Minor degrees of necrosis (less than 5%) and/or separation of vaginal suture lines occurred in five patients without marked loss of the flaps. Vaginal caliber and depth are excellent in ten patients (91%) after follow-up of 1-22 months. The short gracilis flap is an excellent alternative to the more bulky gracilis flap, which derives its blood supply from perforating branches of the femoral artery. Based on our experience, the short gracilis flap provides adequately vascularized tissue for vulvovaginal reconstruction in patients after radical pelvic surgery, but should not be used in patients who have received extensive groin irradiation.     

Ha-ras polymorphisms in epithelial ovarian cancer.

Unusual restriction fragment length polymorphisms (RFLPs) of the Ha-ras locus have been found in DNA from leukocytes and tumor tissue of cancer patients. To determine whether rare alleles would be observed frequently in patients with ovarian cancer, Ha-ras RFLPs were studied in DNA from 42 different ovarian epithelial tumors and from the peripheral blood leukocytes of 76 normal individuals. Four common, seven intermediate, and seven rare alleles were detected overall. Similar fractions of rare alleles were found in DNA from ovarian cancers and from the peripheral blood of normal individuals. Thus, the frequency of unusual Ha-ras RFLPs did not distinguish patients with ovarian cancers from apparently healthy individuals.     

Radical hysterectomy in obese women.

OBJECTIVE: To determine whether there is a significant difference in treatment outcome and acute and chronic complications in obese compared with non-obese women having radical hysterectomy for early-stage cervical cancer. METHODS: From 1970-1985, 320 women underwent a class III radical hysterectomy and pelvic lymphadenectomy for stage IB-IIA invasive cervical cancer at Duke University Medical Center. Forty-three of these women weighed at least 80 kg and had a body weight greater than 25% above their ideal predicted weight. These women were compared to 277 patients with normal weight for height. RESULTS: The median age, incidence of diabetes mellitus and hypertension, number of nodes removed at lymphadenectomy, disease-free survival, length of hospital stay, and serious surgical or medical complications were the same in the two groups. However, obese patients had a significantly higher estimated blood loss, greater incidence of transfusion, and longer operative times. CONCLUSIONS: Survival is not compromised and the incidence of serious complications is not increased in obese patients treated with radical hysterectomy, but the operative technique is more difficult, the procedure lasts longer, and the surgery is associated with greater blood loss.     

Trisomy 18 with Ectopia Cordis, Omphalocele, and Ventricular Septal Defect: Case Report

A case of thoracoabdominal ectopia cordis was diagnosed by ultrasonography at 21 week's gestation. Chromosomal analysis showed full trisomy 18. This case supports the associationl of thoracoabdominal ectopia cordis (Cantrell's pentad) with chromosomal errors, specifically trisomy 18.     

A phase I/II study of high-dose cyclophosphamide,cisplatin, and thioTEPA followed by autologous bone marrow and granulocyte colony-stimulating factor-primed peripheral-blood progenitor cells in patients with advanced malignancies

 The purpose of the present study was to determine the maximally tolerated dose of thioTEPA given with fixed high-dose cyclophosphamide (CPA) and cisplatin (cDDP) followed by autologous bone marrow (ABM) with or without granulocyte colonystimulating factor (G-CSF)-primed peripheral-blood progenitor cells (PBPCs) in patients with advanced malignancies. Patients were required to have histologically documented malignancies and adequate renal, hepatic, pulmonary, and cardiac function. CPA was given at 1,875 mg/m² per day as a 1-h i.v. infusion for 3 consecutive days, and cDDP was given at 55 mg/m² per day as a 24-h continuous i.v. infusion over 3 days concurrently with CPA. ThioTEPA was given once as a 1-h i.v. infusion (300–900 mg/m²) either following (the first 13 patients) or prior to CPA and cDDP. In all, 31 patients received PBPCs. A total of 46 patients were treated. There were 6 deaths among the 15 patients who did not receive PBPCs (13 received thioTEPA following CPA and cDDP). Among the other 31 patients who received PBPCs (all of whom also received thioTEPA prior to CPA and cDDP), there were 4 deaths, all involving patients with refractory ovarian carcinoma. The main toxicities were mucositis, esophagitis, hepatotoxicity, and nephrotoxicity. The median time required to achieve an absolute neutrophil count of 500 μl was 10 days (range, 9–12 days) for those who received PBPCs and 15 days (range, 15–34 days) for those who did not receive PBPCs. Altogether, 47% of the major organ toxicities (grades 3 and 4 renal, hepatic, and cardiac toxicities) occurred among the 15 patients who did not receive PBPCs, although these patients received thioTEPA at the lowest 2 dose levels. There were 3 complete responses and 22 partial responses among 35 evaluable patients (overall response rate, 71%), with the median duration of response being 3.5 months (range, 2–17 months). The maximally tolerated dose of thioTEPA was 600 mg/m² given as a 1-h i.v. infusion on the day prior to CPA and cDDP administration. The combination of high-dose CPA, cDDP, and thioTEPA is a well-tolerated regimen when thioTEPA is given prior to CPA and cDDP and when the combination also includes PBPCs in addition to ABM. This regimen is active in a variety of malignancies. Received: 15 February 1995/Accepted: 22 May 1995     

Immunoscintigraphy of ovarian endometriosis. A preliminary study

CA-125 is a membrane antigen detected in the serum of some women with gynaecological disease including endometriosis. We attempted to use a radioiodinated anti-CA-125 monoclonal antibody, OC-125, to image ovarian endometriosis using immunoscintigraphy. Two women with significant endometriosis and normal serum CA-125 levels had positive immunoscintigraphy. In one woman, all areas of endometriosis were imaged; in the other, endometriosis in one affected ovary was seen, but uptake in the other ovary was less than the extent of the disease.     

Laparoscopic intracorporeal ultrasound versus fluoroscopic intraoperative cholangiography

BACKGROUND: The purpose of this study was to compare the results of laparoscopic intracorporeal ultrasound (LICU) to those of fluoroscopic intraoperative cholangiography (FIOC) during laparoscopic cholecystectomy (LC) after the initial learning curve for LICU. METHODS: Data were prospectively collected on patients undergoing LC. A consecutive series of 394 LICU patients was compared to a consecutive series of 400 FIOC patients when each imaging procedure was preferentially performed. Patients during the transition period, including the first 100 LICU patients, were excluded. RESULTS: Demographics and preoperative diagnoses were similar in the two groups. Excluding those who were converted to open cholecystectomy and those in whom an imaging exam was not attempted, FIOC was successful in 361 of 374 (97%) patients and LICU was successful in 377 of 380 (99%) patients (p < 0.03). The mean times (+/-SEM) to complete FIOC and LICU were 16.0 (+/-0.5) min and 5.1 (+/-0.1) min (p < 0.0001), respectively, Choledocholithiasis was detected in 25 patients (7%) undergoing FIOC and in 39 patients (10%) undergoing LICU (p = 0.1). During LICU the common bile duct was visualized in continuity from the cystic duct to ampulla in 90% of cases. The common bile duct could not be completely visualized in continuity at the middle or distal portion of the common bile duct in 5% and 6% of LICU cases, respectively. One LICU patient (0.3%) with an incompletely visualized duct had a suspected stone confirmed by postoperative endoscopic retrograde cholangiopancreaticography (ERCP). One patient with negative FIOC (0.3%) had a retained stone treated by postoperative ERCP. CONCLUSION: LICU is safe and accurate, and it permits a more rapid evaluation of bile duct stones than FIOC during laparoscopic cholecystectomy. The false-negative rate of both imaging techniques is less than 1%.     

Why women douche and why they may or may not stop

BACKGROUND: Although douching is common, it is a potentially harmful habit. GOAL: We studied attitudes and knowledge around the behavior of douching. STUDY DESIGN: Of 1,200 women enrolled in this multisite study, 532 douched and answered questions on a structured interview regarding douching behaviors. RESULTS: Over half had douched for 5 or more years. Douching was most often initiated on the recommendation of female relatives and practiced for reasons of hygiene. Half of women considered douching to be healthy. Those who considered douching to be unhealthy reported that douching may disrupt vaginal flora but did not cite more serious risks. Nonetheless, women who had been advised by a health professional to stop douching were less likely to consider douching healthful and were more likely to have tried to stop. CONCLUSION: Women had a limited understanding of potential adverse health consequences associated with douching. Targeted health messages may influence women to initiate douching cessation.     

Donor cell replacement in mice transplanted in utero is limited by immune-independent mechanisms

In utero transplantation (IUTx) therapy with allogeneic cells results in negligible peripheral blood (PBL) chimerism in nonablated humans with progressive diseases. IUTx has been successful only in immunocompromised fetuses. Because early treatment has great potential for halting disease progression, mechanisms preventing cell expansion must be identified and corrected. The hypothesis that factors in addition to allogenicity are responsible for low-level expansion is tested here by transplanting congenic cells into nonablated normal and mucopolycaccharidosis type VII (MPSVII) murine fetuses. MPSVII mice lack the enzyme beta-glucuronidase (GUSB-), accumulate glycosaminoglycans, and progressively develop severe storage disease. Low levels of enzyme can reverse storage. Evidence presented elsewhere showed that allogeneic donor cells overexpressing GUSB are negligible and their corrective effects are lost post-IUTx in MPSVII mice. We find that (1) congenic donor PBL cells, like allogeneic cells, are negligible in PBL of normal GUSB+ and MPSVII GUSB- hosts post-IUTx; (2) congenic, unlike allogeneic cells, are retained long term in both GUSB+ and GUSB- recipients; and (3) sufficient GUSB is produced to alleviate storage for up to 11.5 months in multiple tissues of GUSB- hosts. GUSB+ and GUSB- animals repopulate to a similar extent, indicating that donor GUSB enzyme does not initiate an immune response in the MPSVII null recipients. We conclude that the initial expansion of congenic and allogeneic cells is limited post-IUTx by non-immune-related mechanisms and the level of PBL cells is not necessarily indicative of graft failure following congenic IUTx. The mechanism limiting initial expansion may differ from that supporting long-term cell retention.
