RESUMEN

BACKGROUND: The scapular free flap (SFF) is essential in complex reconstructive surgery and often indicated in complex defects with compromised or poor local tissue integrity. This review aims to assess the versatility and reliability of the SFF during reconstruction. METHODS: A comprehensive literature review of multiple databases was conducted following the PRISMA guidelines. An analysis of pooled data was performed to evaluate flap failure rate for any anatomical unit using SFF as the primary endpoints. Secondary endpoints included other complication rates after reconstruction such as partial flap loss, revision surgery, fistula, hematoma, and infection. RESULTS: A total of 110 articles were included, with 1447 pooled flaps. The main recipient site was the head and neck region (89.0%). Major indications for reconstruction were malignancy (55.3%), burns (19.2%), and trauma (9.3%). The most common types of flaps were osteocutaneous (23.3%), cutaneous (22.6%), and chimeric (18.0%). The pooled flap failure rate was 2% (95%CI: 1%-4%). No significant heterogeneity was present across studies (Q statistic 20.2, p = .69; I2 .00%, p = .685). Nonscapular supplementary flaps and grafts were required in 61 cases. The average length and surface area of bone flaps were 7.2 cm and 24.8cm2, respectively. The average skin paddle area was 134.2cm2. CONCLUSION: The SFF is a useful adjunct in the reconstructive surgeon's armamentarium as evidence by its intrinsic versatility and diverse clinical indications. Our data suggest a low failure rate in multicomponent defect reconstruction, especially in head and neck surgery. SFFs enable incorporation of multiple tissue types and customizable dimensions-both for vascularized bone and cutaneous skin-augmenting its value in the microsurgeon's repertoire as a chimeric flap. Further research is necessary to overcome the conventional barriers to SFF utilization and to better comprehend the specific scenarios in which the SFF can serve as the preferred alternative workhorse flap.

RESUMEN

INTRODUCTION: Metabolic syndrome (MetS) is characterized by cardiometabolic abnormalities such as hypertension, obesity, diabetes, or dyslipidemia. This study aims to evaluate the association of MetS on the postoperative outcomes of ventral, umbilical, and epigastric hernia repair using component separation. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who underwent ventral, umbilical, and epigastric hernia repair with component separation between 2015 and 2021. MetS status was defined as patients receiving medical treatment for diabetes mellitus and hypertension, with a body mass index greater than 30 kg/m2. Propensity matching was performed to generate two balanced cohorts with and without MetS. T-tests and Fisher's Exact tests assessed group differences. Logistic regression models evaluated complications between the groups. RESULTS: After propensity score matching, 3930 patients were included in the analysis, with 1965 in each group (MetS versus non-MetS). Significant differences were observed in the severity and clinical presentation of hernias between the groups. The MetS cohort had higher rates of incarcerated hernia (39.1% versus 33.2%; P < 0.001), and recurrent ventral hernia (42.7% versus 36.5%; P < 0.001) compared to the non-MetS cohort. The MetS group demonstrated significantly increased rates of renal insufficiency (P = 0.026), unplanned intubation (P = 0.003), cardiac arrest (P = 0.005), and reoperation rates (P = 0.002) than the non-MetS cohort. Logistic regression models demonstrated higher likelihood of postoperative complications in the MetS group, including mild systemic complications (OR 1.25; 95%CI 1.030-1.518; P = 0.024), severe systemic complications (OR 1.63; 95%CI 1.248-2.120; P < 0.001), and reoperation (OR 1.47; 95%CI 1.158-1.866; P = 0.002). There were no significant differences in the rates of 30-d wound complications between groups. CONCLUSIONS: The presence of metabolic derangement appears to be associated with adverse postoperative medical outcomes and increased reoperation rates after hernia repair with component separation. These findings highlight the importance of optimizing preoperative comorbidities as surgeons counsel patients with MetS.

RESUMEN

INTRODUCTION: The quality and readability of online health information are sometimes suboptimal, reducing their usefulness to patients. Manual evaluation of online medical information is time-consuming and error-prone. This study automates content analysis and readability improvement of private-practice plastic surgery webpages using ChatGPT. METHODS: The first 70 Google search results of "breast implant size factors" and "breast implant size decision" were screened. ChatGPT 3.5 and 4.0 were utilized with two prompts (1: general, 2: specific) to automate content analysis and rewrite webpages with improved readability. ChatGPT content analysis outputs were classified as hallucination (false positive), accurate (true positive or true negative), or omission (false negative) using human-rated scores as a benchmark. Six readability metric scores of original and revised webpage texts were compared. RESULTS: Seventy-five webpages were included. Significant improvements were achieved from baseline in six readability metric scores using a specific-instruction prompt with ChatGPT 3.5 (all P ≤ 0.05). No further improvements in readability scores were achieved with ChatGPT 4.0. Rates of hallucination, accuracy, and omission in ChatGPT content scoring varied widely between decision-making factors. Compared to ChatGPT 3.5, average accuracy rates increased while omission rates decreased with ChatGPT 4.0 content analysis output. CONCLUSIONS: ChatGPT offers an innovative approach to enhancing the quality of online medical information and expanding the capabilities of plastic surgery research and practice. Automation of content analysis is limited by ChatGPT 3.5's high omission rates and ChatGPT 4.0's high hallucination rates. Our results also underscore the importance of iterative prompt design to optimize ChatGPT performance in research tasks.

RESUMEN

Immediate lymphatic reconstruction (ILR) is recognized as a surgical approach used to reduce the risk of developing secondary lymphedema, and evidence demonstrating the efficacy of ILR is favorable. Our Lymphatic Center has become a centralized location offering ILR for the risk-reduction in breast cancer-related lymphedema (BCRL) in New England. Over the course of our experience, we made several modifications and adapted our approach to enhance the operative success of this procedure. These include advancements in our use of indocyanine green (ICG) imaging to identify baseline lymphatic anatomical variation, utilization of fluorescein isothiocyanate for lymphatic vessel visualization, application of the lymphosome concept to guide arm injection sites, verification of anastomotic patency (using ICG), localization of reconstruction to guide radiation therapy, incorporation of intraoperative tools to facilitate better anatomic visualization of the axilla, and addition of a lower extremity vein graft to mitigate venous-related complications. Collecting information from each surgery in a standardized manner, including intraoperative lymphatic channel measurements, and deploying clips for possible future radiation exposure, enables future studies on ILR patient outcomes. In this contribution, we aimed to share our institutional modifications with the surgical community to facilitate further adoption, conversation, and advancement of ILR for the risk-reduction in BCRL.

RESUMEN

BACKGROUND: Bakuchiol is a topical cosmeceutical marketed as a retinoid alternative. Human clinical trial data on bakuchiol’s efficacy for the treatment of dermatologic conditions has not been thoroughly evaluated. OBJECTIVE: To review human clinical trials using topical formulations containing bakuchiol in the treatment of facial skin disorders. MATERIALS AND METHODS: A comprehensive electronic search of Cochrane Library, PubMed, EMBASE, and Web of Science was conducted on August 28, 2022, using the search terms “bakuchiol” and “UP256.” Study characteristics, measured outcomes, significant results, and stated limitations were extracted.  Results: Fifteen human clinical trials were analyzed. Dermatologic conditions treated included aging, acne, and post-inflammatory hyperpigmentation. Twelve trials were unblinded, open-label trials without a control group. Ten trials used a combination therapy containing bakuchiol. Four trials did not specify the dose or concentration of bakuchiol in treatment regimens. The heterogeneity of treatments, study designs, and measured outcomes makes meta-analysis unfeasible.  Conclusion: Trials lack methodologic rigor, which introduces a high risk of bias in reported outcomes. The use of combination topical formulations containing bakuchiol limits the comparison of bakuchiol’s efficacy with retinoids. Continued research with an improved trial design is needed.J Drugs Dermatol. 2024;23(4): doi:10.36849/JDD.7763.

RESUMEN

Background: Wellness programs are especially important in residency. However, the resources available to plastic surgery residents through residency wellness programs have not been described. This study reports current plastic surgery residency wellness programs' organization, leadership, and resources. Methods: An anonymous and voluntary e-mail survey was sent to 106 plastic surgery residency program directors through May and June 2022. Features of residency wellness programs were detailed, and program directors' sentiments towards residency wellness programs were evaluated. Results: A 30.2% (32 of 106) complete response rate was achieved. Nearly 90% (87.5%, 28 of 32) of program directors indicated the presence of a wellness program. More than 75% (21 of 28) of programs are supported by the Office of Graduate Medical Education. Wellness events were offered by 92.9% (26 of 28) of programs. More than half of programs offered resources for mental health, physical health, mentorship, and protected time. Several resources were associated with the presence of wellness leadership roles, suggesting residents can positively shape wellness program offerings. Program directors strongly indicated that wellness programs are important, relevant, and effective. Additionally, 75% (24 of 32) report a desire to learn about wellness programs at other plastic surgery residency programs. Conclusions: Resources offered through plastic surgery residency wellness programs are comparable to those in other specialties. However, plastic surgery programs vary in the resources offered to residents and barriers to access exist. Greater involvement of residents in plastic surgery wellness programs may better support physician wellness.

RESUMEN

BACKGROUND: Metabolic syndrome (MetS) is a cluster of cardiometabolic abnormalities including hypertension, obesity, insulin resistance, and dyslipidemia. The safety profiles of patients with MetS undergoing breast reconstruction remain underreported. This study aims to evaluate the impact of MetS on the BR decision-making process and postoperative complication rates. METHODS: The ACS-NSQIP database was utilized to identify women who underwent BR between 2012 and 2021. Baseline characteristics were compared based on the presence of MetS, defined as patients receiving medical treatment for diabetes mellitus and hypertension, with a body mass index greater than 30 kg/m2. Group differences were assessed using t tests and Fisher's exact tests. Multivariate logistic regression models evaluated postoperative complications between the groups. RESULTS: A total of 160,115 patients underwent BR. A total of 4570 had a diagnosis of MetS compared to 155,545 without MetS. No statistically significant differences were observed in the type of BR patients received across cohorts. Logistic regression models demonstrated a higher likelihood of postoperative wound complications (OR 2.21; 95% CI 1.399, 3.478; p = 0.001), and readmission rates (OR 2.045; 95% CI 1.337, 3.128; p = 0.001) in the MetS group compared to the non-MetS patients. No significant differences were identified in other postoperative complications between groups. CONCLUSIONS: Patients with MetS appear to have an increased risk of postoperative wound complications and readmission after breast reconstruction. The synergistic effects of these comorbidities on postoperative outcomes underscore the importance of addressing MetS as a holistic condition and considering choosing Delayed breast reconstruction over Immediate Breast Reconstruction in this population. Thus, integrating MetS management and patient counseling at various stages of BR may improve outcomes and facilitate patient decision-making.

RESUMEN

Chemical peeling treats facial cutaneous aging and may avoid risks in patients with sensitive skin, darker skin types, limited finances, or concern for side effects of other resurfacing techniques. Tolerability and improvement of photoaging using a combination peel containing 6% trichloroacetic acid and 12% lactic acid for treatment of mild-to-moderate signs of facial photoaging were assessed. This is a prospective, single-center, single-arm, study of 32 female subjects with mild-to-moderate signs of facial aging and Fitzpatrick Skin Types I-V treated with three monthly treatments of a combination peel containing 6% trichloroacetic acid and 12% lactic acid. After 3 treatments, there were statistically significant improvements in clarity, brightness, redness, pigmentation, fine lines, tactile and visual roughness, and overall appearance scores. Subjective improvements in photoaging parameters varied from 53% (fine lines) to 91% (clarity/brightness). Three treatments with a combination peel containing 6% trichloroacetic acid and 12% lactic acid achieved improvements in signs of facial photoaging. This procedure is safe and effective at treating cutaneous aging for all skin types and a viable option for patients who wish to avoid other resurfacing techniques such as laser resurfacing, microneedling among others.

RESUMEN

The ongoing challenges posed by COVID-19 are concerning for their impact on successful detection and recognition of melanoma as total body skin examinations and skin biopsies are critical for identifying early-stage melanoma and intervening before progression to metastatic disease. A comprehensive electronic search of PubMed/MEDLINE was conducted on or before August 1, 2022, using the search terms ("skin" AND "COVID-19"), (["skin cancer" AND "COVID-19"] OR ["skin cancer" AND "coronavirus"]), (["melanoma" AND "COVID-19"] OR ["melanoma" AND "coronavirus"]), ("dermatology" AND "COVID-19"), and ("cutaneous" AND "COVID-19"). Eight articles representing Belgium, Chile, France, Germany, Spain, the United Kingdom, and the United States were included. Four articles analyzed changes in the proportion of in situ melanoma at diagnosis and consistently reported decreases, with an overall decrease ranging from 7.6 to 40.4%. Five studies analyzed changes in the proportion of melanoma diagnoses by staging, but no clear changes in staging patterns were observed. Five studies analyzed changes in the mean Breslow thickness of melanoma diagnoses and consistently reported increases, with an overall increase ranging from 4.0 to 38%. Disruptions to proper diagnosis and treatment of melanoma are creating undue morbidity, mortality, and healthcare costs as the pandemic continues. Continued research with improved, centralized data collection is needed to better address the COVID-19 pandemic's ongoing challenge to appropriate detection and treatment of melanoma.

RESUMEN

Breast augmentation is one of the most frequently performed aesthetic procedures in the United States. Online information is often used by patients to make decisions when undergoing cosmetic procedures. It is vital that online medical information includes relevant decision-making factors and uses language that is understandable to broad patient audiences. Ideally, online resources should aid patient decisions in aesthetic surgical planning, especially implant size selection for breast augmentation. We describe patient decision-making factors and readability of breast implant size selection recommended by private practice plastic surgery webpages. Methods: Using a depersonalized, anonymous query to Google search engine, the terms "breast implant size factors" and "breast implant size decision" were searched, and 52 plastic surgery private practice webpages were identified. Webpages were analyzed for reported decision-making factors of implant size selection. Readability analyses of webpages were performed with Readability Studio and Hemingway Editor. Results: The two major decision-making factors for implant size selection reported by webpages were body/tissue-based measurements and surgeon input. Ten factors related to patient lifestyle, surgical goals, and procedural options were also identified. Average webpage scores for five readability measures exceeded recommended levels for medical information. Conclusions: Reported decision-making factors for implant size selection emphasize a plastic surgeon's expertise but may enhance the patient's role in preoperative planning. Webpages describing breast implant size selection exceed the sixth and eighth grade reading levels recommended by the AMA and NIH, respectively. Improving the readability of webpages will refine the role of online medical information in preoperative planning of breast augmentation.

RESUMEN

The repertoire of coronavirus disease 2019 (COVID-19)-mediated adverse health outcomes has continued to expand in infected patients, including the susceptibility to developing long-COVID; however, the molecular underpinnings at the cellular level are poorly defined. In this study, we report that SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection triggers host cell genome instability by modulating the expression of molecules of DNA repair and mutagenic translesion synthesis. Further, SARS-CoV-2 infection causes genetic alterations, such as increased mutagenesis, telomere dysregulation, and elevated microsatellite instability (MSI). The MSI phenotype was coupled to reduced MLH1, MSH6, and MSH2 in infected cells. Strikingly, pre-treatment of cells with the REV1-targeting translesion DNA synthesis inhibitor, JH-RE-06, suppresses SARS-CoV-2 proliferation and dramatically represses the SARS-CoV-2-dependent genome instability. Mechanistically, JH-RE-06 treatment induces autophagy, which we hypothesize limits SARS-CoV-2 proliferation and, therefore, the hijacking of host-cell genome instability pathways. These results have implications for understanding the pathobiological consequences of COVID-19.

RESUMEN

The purpose of this study is to determine the association between gynecologic oncology fellowship training factors, including fellowship length, and a career in academic medicine. A survey was sent to all 980 gynecologic oncologists identified via the SGO membership directory. The survey questions focused on demographics, fellowship training, practice- type, and research involvement. Demographics of the study population and survey responses were reported using frequencies and percentages. Chi-squared tests were used to test for associations between selected survey responses and length of fellowship. The authors received 410 (42 %) responses. Most respondents (60 %) graduated from a 3-year fellowship, while 27 and 13 % attended 2- and 4-year fellowships, respectively. Practice descriptions included academic/university (52 %), community/private practice (21 %), private practice with academic appointment (20 %), and other (7 %). A majority (64 %) reported current involvement in research as a principal investigator (PI); however, 54 % reported spending 10 % or less of their time in research-related activities. Approximately half reported that their fellowship research experience contributed to their current practice. Graduates of 3- and 4-year fellowships had similar rates of employment in academic/university settings (58 and 52 %, respectively). Graduates of 4-year fellowships were more likely to hold an advanced degree and 11 or more publications at completion of fellowship. A majority of graduates of a gynecologic oncology fellowship practice in an academic/university setting and are involved in research. Fellowship length does not correlate with a current academic medicine appointment. Graduates of 4-year fellowships are more likely to hold additional advanced degrees and more publications.

RESUMEN

BACKGROUND AND OBJECTIVES: To evaluate the feasibility of a minimally invasive approach for hysterectomy for benign disease at a university teaching hospital. METHODS: Five hundred thirty-seven consecutive patients underwent hysterectomy for benign disease at Penn State Milton S. Hershey Medical Center in 2010. No cases were excluded. Minimally invasive approaches included total vaginal hysterectomy, laparoscopy-assisted vaginal hysterectomy, total laparoscopic hysterectomy, and laparoscopic supracervical hysterectomy. All surgeries were completed with the resident as the primary surgeon or first assistant. RESULTS: The median age was 45 years, the median body mass index was 30 kg/m2, the median estimated uterine size was 11 cm, and 22% of patients had a prior cesarean section. Of the 537 hysterectomies, 526 (98%) were started with a minimally invasive approach and 517 (96%) were completed in that fashion; thus only 9 conversions (2%) were required. Of the cases in which a minimally invasive approach was used, 16% were vaginal and 84% were laparoscopic. The median operative time was 86 minutes, the median blood loss was 95 mL, the median hospital stay was 1 day, and the median uterine weight was 199 g. For the minimally invasive hysterectomies, there was a 5% major complication rate. CONCLUSION: Our residency training institution completed 96% of 537 hysterectomies using a minimally invasive approach while maintaining an acceptable operative time, amount of blood loss, hospital stay, and complication rate. Thus our study supports that a minimally invasive approach for hysterectomy for benign disease at an academic resident teaching facility is feasible.

RESUMEN

BACKGROUND AND OBJECTIVES: The purpose of our study is to evaluate the incidence of cervical recurrence after laparoscopic supracervical hysterectomy for ovarian cancer debulking or staging. METHODS: From a prospective surgical database, we identified 51 cases of laparoscopic supracervical hysterectomy for ovarian cancer debulking or staging. No cases were excluded. RESULTS: From 2009 to 2012, 51 patients were identified. The median age was 62 years (range, 32-83 years), and the median body mass index was 29 kg/m2 (range, 16-41 kg/m2). Medical comorbidities were present in 40 patients (78%), and 53% had prior abdominal surgery. The median operative time was 2 hours (range, 1-3.5 hours), and the median blood loss was 200 mL (range, 50-900 mL). The median length of stay was 1 day (range, 0-12 days). The stage was I in 12 patients, II in 6, and III/IV in 33. At a median follow-up time of 1.7 years (range, 0.3-2.6 years), 20 patients (39%) had recurrence of cancer, with a median time of recurrence of 1.1 years (range, 0.3-2.3 years). All recurrences were in the abdomen or pelvis except for 1 axillary node recurrence and 1 recurrence in the distal vagina. There were no recurrences in the remaining cervical stump. No patient had a postoperative vaginal cuff infection. Among the 104 cycles of intraperitoneal chemotherapy, there was no vaginal leakage of intraperitoneal chemotherapy. CONCLUSION: Laparoscopic supracervical hysterectomy for ovarian cancer debulking or staging does not result in cervical recurrence.

RESUMEN

BACKGROUND AND OBJECTIVES: The aim of our study is to evaluate the role of electrosurgery and vaginal closure technique in the development of postoperative vaginal cuff dehiscence. METHODS: From prospective surgical databases, we identified 463 patients who underwent total laparoscopic hysterectomy (TLH) for benign disease and 147 patients who underwent laparoscopic-assisted vaginal hysterectomy (LAVH) for cancer. All TLHs and LAVHs were performed entirely by use of electrosurgery, including colpotomy. Colpotomy in the TLH group was performed with Harmonic Ace Curved Shears (Ethicon Endo-Surgery, Cincinnati, OH, USA), and in the LAVH group, it was performed with a monopolar electrosurgical pencil. The main surgical difference was vaginal cuff closure--laparoscopically in the TLH group and vaginally in the LAVH group. RESULTS: Although patients in the LAVH group were at increased risk for poor healing (significantly older, higher body mass index, more medical comorbidities, higher blood loss, and longer operative time), there were no vaginal cuff dehiscences in the LAVH group compared with 17 vaginal cuff dehiscences (4%) in the TLH group (P = .02). CONCLUSION: It does not appear that the increased vaginal cuff dehiscence rate associated with TLH is due to electrosurgery; rather, it is due to the vaginal closure technique.

RESUMEN

BACKGROUND: The potent ribonucleotide reductase (RNR) inhibitor 3-aminopyridine-2-carboxyaldehyde-thiosemicarbazone (3-AP) was tested as a chemosensitizer for restored cisplatin-mediated cytotoxicity in platinum-resistant ovarian cancer. METHODS: Preclinical in vitro platinum-resistant ovarian cancer cell survival, RNR activity, and DNA damage assays were done after cisplatin or cisplatin plus 3-AP treatments. Six women with platinum-resistant ovarian cancer underwent four-day 3-AP (96 mg/m(2), day one to four) and cisplatin (25 mg/m(2), day two and three) infusions every 21 days until disease progression or adverse effects prohibited further therapy. Pre-therapy ovarian cancer tissues were analyzed by immunohistochemistry for RNR subunit expression as an indicator of cisplatin plus 3-AP treatment response. RESULTS: 3-AP preceding cisplatin exposure in platinum-resistant ovarian cancer cells was not as effective as sequencing cisplatin plus 3-AP together in cell survival assays. Platinum-mediated DNA damage (i.e., γH2AX foci) resolved quickly after cisplatin-alone or 3-AP preceding cisplatin exposure, but persisted after a cisplatin plus 3-AP sequence. On trial, 25 four-day overlapping 3-AP and cisplatin cycles were administered to six women (median 4.2 cycles per patient). 3-AP-related methemoglobinemia (range seven to 10%) occurred in two (33%) of six women, halting trial accrual. CONCLUSIONS: When sequenced cisplatin plus 3-AP, RNR inhibition restored platinum-sensitivity in platinum-resistant ovarian cancers. 3-AP (96 mg/m(2)) infusions produced modest methemoglobinemia, the expected consequence of ribonucleotide reductase inhibitors disrupting collateral proteins containing iron. TRIAL REGISTRY: ClinicalTrials.gov NCT00081276.

RESUMEN

Endometrial cancer is the most common gynecologic malignancy in the United States, with over 40,000 cases diagnosed each year. While a majority of cases are diagnosed in post-menopausal women, up to 14% of cases will be in pre-menopausal women, including 4% diagnosed in women less than 40 years of age. While hysterectomy with bilateral salpingo-oophorectomy with assessment of the retroperitoneal lymph nodes is standard initial treatment for endometrial cancer, younger women may desire fertility sparing options. The decision to proceed with conservative management in this younger patient population is associated with multiple complexities, including the inherent oncologic risks of an inadequately staged and treated endometrial cancer, the risk of a synchronous or meta-synchronous cancer, the increased risk of an inherited genetic predisposition to malignancy and the lack of uniformity in the medical management and surveillance. In this review we will discuss the conservative management of endometrial cancer, specifically the role of progestin hormonal therapy, including the risks associated with non-standard care, appropriate candidate selection and work up, expected outcomes, various progestin agents and recommended follow-up.

RESUMEN

OBJECTIVE: The opioid growth factor (OGF) and its receptor (OGFr), serve as inhibitory axis regulating cell proliferation in normal cells and cancer. We investigated the presence and relative expression of OGF and OGFr in normal human ovarian surface epithelial (HOSE) cells, benign ovarian cysts, and ovarian cancers. METHODS: Surgical samples of 16 patients with ovarian cancer and 27 patients with ovarian benign cysts were obtained intraoperatively. HOSE were collected by scraping the surface of normal ovaries of 10 post menopausal women undergoing hysterectomy and oophorectomy. Semiquantitative immunohistochemistry was used to assess the presence, distribution, and levels of OGF and OGFr. Receptor binding assays measured binding capacity and affinity of OGFr for radiolabeled OGF. RESULTS: OGF and OGFr were present in HOSE cells, ovarian cysts, and ovarian cancers. Compared to HOSE cells, OGF and OGFr protein levels were reduced 29% and 34% (p<0.001), respectively, in ovarian cysts, and decreased 58% and 48% (p<0.001), respectively, in ovarian cancers. Binding assays revealed 5.4 fold fewer OGFr binding sites in cancers than cysts (p<0.05). Levels of OGF and OGFr were comparable in primary, metastatic, or recurrent ovarian cancers. CONCLUSION: We have shown that a native opioid pathway, the OGF-OGFr axis, is present in human ovarian cancer. Importantly, the expression of OGF and OGFr is diminished in human ovarian cancer. As OGF and OGFr normally function in maintaining cell proliferation, therapy to harness OGF/OGFr function could provide a useful biologic-based treatment for human ovarian cancer.

RESUMEN

CONTEXT: Prophylactic intraoperative ureteral stent placement is performed to decrease operative ureteric injury, though few data are available on the effectiveness of this procedure, and no data are available on its cost. OBJECTIVE: To analyze the cost of prophylactic intraoperative cystoscopic ureteral stents in gynecologic surgery. METHODS: All cases of prophylactic ureteral stent placement performed in gynecologic surgery during a 1-year period were identified and retrospectively reviewed through the electronic medical records database of Summa Health System. Costs were obtained through the Healthcare Cost Accounting System. The principles of cost-effective analysis were used (ie, explicit and detailed descriptions of costs and cost-effectiveness statistics). Importantly, we evaluated cost and not charges or financial model estimates. In addition, we obtained the contribution margins (ie, the hospital's net profit or loss) for prophylactic ureteral stent placement. Other gynecologic procedures were also analyzed. RESULTS: Among 792 major inpatient gynecologic procedures, 18 cases of prophylactic intraoperative ureteral stents were identified. Median costs were as follows: additional cost of prophylactic intraoperative ureteral stenting, $1580; additional cost of surgical resources, $770; cost of ureteral catheters, $427; cost of surgeons, $383. The contribution margins per case for various gynecologic surgical procedures were as follows: oophorectomy, $2804 profit; abdominal hysterectomy, $2649 profit; laparoscopically assisted vaginal hysterectomy (LAVH), $1760 profit. When intraoperative ureteral stenting was added, the contribution margins changed to the following: oophorectomy, $782 profit; abdominal hysterectomy, $627 profit; LAVH, $262 loss. Overall, the contribution margin profit was decreased by about 85%, from $2400 to $380. CONCLUSION: Prophylactic intraoperative ureteral stenting in gynecologic surgery decreases a hospital's contribution margin. Because of the expense of this procedure, as well as scientific data suggesting a lack of effectiveness, the authors argue that prophylactic intraoperative ureteral stenting should not be used in gynecologic surgery to decrease operative ureteric injury.
