The 2011 Pediatric Emergency Mass Critical Care Task Force recommended that expected duration of critical care be incorporated into resource allocation algorithms. We aimed to determine whether currently available pediatric illness severity scores can predict duration of critical care resource use.

Design:Retrospective cohort study.Setting:Seattle Children’s Hospital.Patients:PICU patients admitted 2016–2018 for greater than or equal to 12 hours (n = 3,206).Interventions:None.Measurements and Main Results:We developed logistic and linear regression models in two-thirds of the cohort to predict need for and duration of PICU resources based on Pediatric Risk of Mortality-III, Pediatric Index of Mortality-3, and serial Pediatric Logistic Organ Dysfunction-2 scores. We tested the predictive accuracy of the models with the highest area under the receiver operating characteristic curve (need for each resource) and R2 (duration of use) in a validation cohort of the remaining one of three of the sample and among patients admitted during one-third of the sample and among patients admitted during surges of respiratory illness. Pediatric Logistic Organ Dysfunction score calculated 12 hours postadmission had higher predictive accuracy than either Pediatric Risk of Mortality or Pediatric Index of Mortality scores. Models incorporating 12-hour Pediatric Logistic Organ Dysfunction score, age, Pediatric Overall Performance Category, Pediatric Cerebral Performance Category, chronic mechanical ventilation, and postoperative status had an area under the receiver operating characteristic curve = 0.8831 for need for any PICU resource (positive predictive value 80.2%, negative predictive value 85.9%) and area under the receiver operating characteristic curve = 0.9157 for mechanical ventilation (positive predictive value 85.7%, negative predictive value 89.2%) within 7 days of admission. Models accurately predicted greater than or equal to 24 hours of any resource use for 78.9% of patients and greater than or equal to 24 hours of ventilation for 83.1%. Model fit and accuracy improved for prediction of resource use within 3 days of admission, and was lower for noninvasive positive pressure ventilation, vasoactive infusions, continuous renal replacement therapy, extracorporeal membrane oxygenation, and length of stay.Conclusions:A model incorporating 12-hour Pediatric Logistic Organ Dysfunction score performed well in estimating how long patients may require PICU resources, especially mechanical ventilation. A pediatric disaster triage algorithm that includes both likelihood for survival and for requiring critical care resources could minimize subjectivity in resource allocation decision-making. ]]>
<![CDATA[The p48 Flow Modulation Device with Hydrophilic Polymer Coating (HPC) for the Treatment of Acutely Ruptured Aneurysms: Early Clinical Experience Using Single Antiplatelet Therapy]]> https://www.researchpad.co/article/N647e3f98-faae-47e9-af23-bc4329ec1637 Flow diversion (FD) remains a potential treatment option following aneurysmal subarachnoid hemorrhage (aSAH) when standard options may not be feasible. However, it should not be considered a first-line treatment due to the need for dual antiplatelet therapy (DAPT). The hydrophilic polymer coating on the p48MW flow diverter (HPC, phenox) is a surface modification that inhibits platelet adhesion. This study aims to report on our early single-center experience using the p48MW HPC (phenox) flow diverter with single antiplatelet therapy (SAPT) following an aSAH.Materials and MethodsWe retrospectively identified all patients who had been treated with the p48MW HPC for aSAH under SAPT. All patients treated within 30 days following an aSAH were included. Any occurrence of thromboembolic and hemorrhagic complications was recorded alongside angiographic and clinical follow-up details.ResultsEight patients were identified. The mean interval between aSAH and FD was 6 days. Of the eight ruptured aneurysms, one was blister-like, one saccular, one mycotic, and the remaining five were dissecting aneurysms. Intraprocedural transient thrombus formation was observed in four patients (50%). Stent thrombosis was observed in one patient (12.5%) on day 3 with spontaneous recanalization after being switched onto DAPT. None of the aneurysms rebled after treatment. Two patients died due to cerebral vasospasm. Complete aneurysm occlusion had been achieved in all but one patient at angiographic follow-up (average 6 months).ConclusionsThis small series highlights the possibility and limitations of using the p48MW HPC with SAPT in ruptured aneurysms. Randomized trials with longer follow-up in larger cohorts are underway. ]]> <![CDATA[Evaluation of the prevalence of sexually transmitted bacterial pathogens in Northern Cyprus by nucleic acid amplification tests, and investigation of the relationship between these pathogens and cervicitis]]> https://www.researchpad.co/article/N8ce5b371-74cd-44d2-8105-5784b58070d2

Objective:

To evaluate the prevalence of pathogens, Chlamydia trachomatis, Neisseria gonorrhea and Trichomonas vaginalis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Ureaplasma parvum in women via multiplex-polymerase chain reaction (PCR)-deoxyribonucleic acid (DNA).

Materials and Methods:

Cervical swabs of 273 women in reproductive age who underwent gynecologic examination in our outpatient clinic were evaluated using the multiplex-PCR-DNA method. The presence of cervicitis, contraceptive methods, marital status, and the number of partners were evaluated.

Results:

One hundred six (39%) of the 273 women had at least one bacterium, 25 women (9.8%) had two bacteria, and three women (1%) had three bacteria. U. urealyticum was the most frequently encountered bacterium (13.9%), followed by M. hominis (12.8%), U. parvum (12.4%), C. trachomatis (5.4%), M. genitalium (2.9%), N. gonorrhea (2.5%), and T. vaginalis (0.3%). Bacterial infection was detected more frequently in women aged <25 years, single, who had multiple partners, and clinically diagnosed with cervicitis. The cervicitis rate was 39% in our study. M. genitalium was significantly more frequent in women with cervicitis than in women without cervicitis (5.6 vs. 1.2%, p=0.005). C. trachomatis and N. gonorrhea, which are often associated with cervicitis, were comparable in women with and without cervicitis.

Conclusion:

Women with clinically diagnosed cervicitis or even with a normal-appearing cervix should be tested using multiplex-real-time PCR-nucleic-acidamplification tests on suspicion of such an infection. M. genitalium is an emerging bacterial agent for cervicitis along with C. trachomatis and N. gonorrhea.

<![CDATA[Induction of labor with oxytocin in pregnancy with low-risk heart disease: A randomized controlled trial]]> https://www.researchpad.co/article/Ne51fc819-477c-42a6-90f2-2c897d486186

Objective:

To compare maternal and perinatal outcomes in pregnant women with underlying heart disease who underwent induction of labor with those who had spontaneous labor.

Materials and Methods:

A total of 50 pregnant women with heart disease who were registered in cardio-obstetric clinic were recruited consecutively between 38-41 weeks’ gestation. Patients with favorable Bishop scores at 38 weeks were randomized into two groups. Induction of labor with oxytocin was performed in one group, and the second group underwent spontaneous onset of labor. Descriptive analysis in terms of mean, standard deviation, and percentage was performed. Unpaired t-test was applied for comparison of two groups using SPPS statistical software.

Results:

No significant difference in the rate of maternal complications was observed between the two groups. No cardiac complications were reported in pregnant females who underwent induction of labor. Fifty-two percent of patients delivered during workday hours when labor was induced, whereas only 24% of pregnant women delivered during working hours who underwent spontaneous delivery. No maternal or neonatal deaths were reported.

Conclusion:

Induction of labor with oxytocin is a relatively safe procedure in women with heart disease, it does not result in any cardiac complications. More patients delivered during daytime when electively induced, which minimized the maternal and fetal risks because obstetric, anesthesiologist, cardiologist, and perinatologist specialists are readily available during the daytime.

<![CDATA[The potential of serum fetal DNA for early diagnosis of gestational trophoblastic disease]]> https://www.researchpad.co/article/N4b4c8dbc-a800-439e-aaf9-17d16fce7720

Objective:

To study cell-free DNA (cfDNA) levels in patients with gestational trophoblastic disease (GTD) in order to test the hypothesis that cfDNA circulating in maternal plasma could provide early detection of GTD.

Materials and Methods:

This study included 32 patients with GTD (complete mole and partial mole) and 30 non-GTD patients in the first trimester of pregnancy with no other medical problems. cfDNA levels in maternal serum were measured using polymerase chain reaction analysis on Y-chromosome–specific sequences.

Results:

cfDNA was found as 327±367 pg on average in the control group and 600±535 pg in the GTD group. Within the GTD group, the partial mole group had an cfDNA average of 636±549 pg, and the complete mole group had an cfDNA average of 563±536 pg. Although there was a statistically significant difference between the GTD group and the control group in terms of cfDNA (p=0.02), there was no statistically significant difference between the complete mole group and the partial mole group (p=0.76).

Conclusion:

Non-parametric analysis of covariance in terms of cfDNA in GTD was performed, thereby increasing its power and revealing a significant difference compared with the control group. This indicates that maternal peripheral bloodstream cfDNA monitoring might be significant in the early diagnosis of GTD.

<![CDATA[Impact of diabetes on gastrointestinal and urinary toxicity after radiotherapy for gynecologic malignancy]]> https://www.researchpad.co/article/Nd35c65be-1fbb-430e-9205-e42dbf81d35b

Objective:

Although diabetes is a common co-morbidity in patients with gynecologic cancer, information about its impact on radiation toxicity in patients with gynecologic cancer treated with external pelvic irradiation is scarce. We aimed to investigate the relation of diabetes with acute toxicity in patients with gynecologic tumors who underwent pelvic +/- paraaortic radiotherapy.

Materials and Methods:

One hundred twenty-nine patients with endometrium or cervix carcinoma were enrolled in the study. Demographic features, presence of diabetes, incidence and severity of upper gastrointestinal (UGIS), lower gastrointestinal (LGIS), and urinary symptoms were recorded from files. Correlation and logistic regression analysis was used to determine the impact of diabetes, age, chemotherapy, paraaortic irradiation on toxicities, and a prediction model was developed.

Results:

The median age of 77 patients with endometrium cancer and 52 cervix cancer was 61 (range, 25-92) years, and 28 (21.7%) of them had diabetes. The median pelvic and tumor/tumor bed dose was 5040+247.65 cGy and 5040+222.91 cGy, respectively. Age and Gr 0 UGIS toxicity were significantly related (p=0.047). LGIS Gr 0 toxicity was found to be significantly higher in patients with diabetes (p=0.045). Gr 0 and 2 UGIS toxicities were both found to be significantly correlated with paraaortic irradiation (both p<0.001). Diabetes is also an important determinant on UGIS toxicity in patients who underwent paraaortic irradiation.

Conclusion:

The correlation we found between toxicity and diabetes, concurrent chemotherapy or paraaortic radiation necessitates special care and risk stratification for patients with diabetes. Further prospective studies with long follow-up and larger patient groups are warranted.

<![CDATA[The prevalence of uterine anomalies in infertile patients with polycystic ovary syndrome: A retrospective study in a tertiary center in Southeastern Turkey]]> https://www.researchpad.co/article/N9e62b06b-be1e-4f1a-bc95-3f94078e5c2b

Objective:

To evaluate the prevalence of uterine anomalies in infertile patients with polycystic ovary syndrome (PCOS) admitted to our tertiary hospital in Southeastern Turkey.

Materials and Methods:

The files of 3033 patients with infertility who presented to the infertility polyclinics were retrospectively analyzed, and uterine anomalies were detected in 131 patients. Seven hundred ten of these patients were evaluated as having PCOS, 55 of whom had uterine anomalies. Patients with PCOS were also divided into two subgroups as those with primary and secondary infertility.

Results:

Of the 3033 patients with infertility who were evaluated, 57 (8%) of 710 infertile patients with PCOS, and 74 (3%) of 2323 non-PCOS patients with infertility had uterine anomalies. A statistically significant difference was found between the two groups (p<0.001), and no significant difference was found between the primary and secondary infertile PCOS subgroups (p=0.3). Septate uteri and arcuate uteri had a high prevalence in the PCOS group, and no t-shaped or hypoplastic uteruses were observed in this group.

Conclusion:

To or knowledge, this is the first study in our region to examine the relation between PCOS and Müllerian anomalies. We demonstrated uterine anomalies and their prevalence in patients with infertility. A more careful examination is required in order to determine the incidence of uterine anomalies in patients with PCOS.

<![CDATA[Long bone fractures in neonatal intensive care units of Afyonkarahisar: Five-year’s experience]]> https://www.researchpad.co/article/Ne36803b2-33ff-483d-9522-798a415f2c1a

Objective:

To determine the incidence of long bone fractures and the clinical features related with these fractures diagnosed in neonatal intensive care units (ICUs) within the province of Afyonkarahisar in Turkey.

Materials and Methods:

The incidence of clavicular fractures was 2.4 in 1000 live births, and the incidence of femoral fractures was 0.32 in 1000 live births at the neonatal ICUs of Afyonkarahisar.

Results:

The incidence of birth trauma-related femoral fracture was 0.16 in 1000 live births, and the incidence of femoral fractures related with osteopenia of prematurity was 1.08 in 1000 live births. The mean gestational age at delivery was 39 weeks, the mean birth weight was 3.308 grams, and the male/female ratio was 3:2 for newborns with birth trauma-related femoral fractures. The mean gestational age at delivery was 30.4 weeks, the mean birth weight was 1256 grams, and the male/female ratio was 2:3 for newborns who had femoral fractures related with osteopenia of prematurity. Breech presentation was present in three newborns (60%), and cesarean section was the type of delivery in all newborns with birth trauma-related femoral fractures.

Conclusion:

Cesarean delivery does not reduce the risk for birth trauma-associated femoral fractures, and there is a risk for femoral fracture in cases of emergency cesarean performed for malpresentation. In order to overcome osteopenia of prematurity, calcium, phosphorus, and vitamin D should be supplemented in premature newborns with intrauterine growth retardation and receive long-term total parenteral nutrition.

<![CDATA[Platelet-rich plasma administration to the lower anterior vaginal wall to improve female sexuality satisfaction]]> https://www.researchpad.co/article/Nd9c5a419-7715-4f00-bf51-7a719f287c90

Objective:

To investigate the effect of platelet-rich plasma (PRP) injection to the lower one-third of the anterior vaginal wall on sexual function, orgasm, and genital perception in women with sexual dysfunction.

Materials and Methods:

Four sessions of PRP were administered to the anterior vaginal wall of 52 female patients with sexual dysfunction and orgasmic disorder [Female Sexual Function Index (FSFI) total score ≤26 orgasmic subdomain score ≤3.75]. Prior to the PRP administrations in each session, the FSFI validated in Turkish, the Female Genital Self-Image Scale (FGSIS), the Female Sexual Distress Scale-Revised (FSDS-R), and Rosenberg’s Self-Esteem Scale were used and in the final follow-up, and the Patient Global Impression of Improvement (PGI-I) was performed and the results were analyzed.

Results:

Following the application of the PRP, the total FSFI score was observed as 27.88±4.80 and the total score was 26 and above in 50% of the patients (p<0.001). Orgasm subdomain scores were found as 2.11±1.20 before the PRP treatment and 4.48±1.14 afterwards (p<0.001). A significant change was observed in all sub-domains after PRP and it was observed that this change started after the first administration (p<0.001). A statistically significant increase was determined in FGSIS genital perception scores, which was significant between the 1st and 2nd months (p<0.001). The FSDS-R scores showed a minimal increase in stress scores as the application number increased, but a statistically significant decrease was observed in the 4th administration (p<0.001). No statistically significant difference was found in Rosenberg Scale scores before and after treatment (p=0.389). High satisfaction was found in PGI-I scores.

Conclusion:

As a minimally invasive method, PRP administration to the distal anterior vaginal wall may improve female sexuality with high satisfaction.

<![CDATA[The “Common Cold” in Frail Older Persons: Impact of Rhinovirus and Coronavirus in a Senior Daycare Center]]> https://www.researchpad.co/article/N5fa4adf7-ea3c-49ee-8f00-466d882a81ff

OBJECTIVE: To evaluate the incidence and impact of rhino‐virus and Coronavirus infections in older persons attending daycare.

DESIGN: Prospective descriptive study.

SETTING: Three senior daycare centers in Rochester, New York.

PATIENTS: Frail older persons and staff members of the daycare centers who developed signs or symptoms of an acute respiratory illness

MEASUREMENTS: Demographic, medical, and physical findings were recorded on subjects at baseline and during respiratory illness. Nasopharyngeal specimens for viral culture as well as acute and convalescent sera for Coronavirus 229E enzyme immunoassay (EIA) were obtained for all illnesses.

RESULTS: During the 44 months of study, 352 older persons experienced 522 illnesses. Thirty‐five (7%) of 522 cultures were positive for rhinovirus and 37 (8%) of 451 serologies were positive for Coronavirus 229E infection. The clinical syndromes associated with rhinovirus and Coronavirus infection were similar and characterized by nasal congestion, cough, and constitutional symptoms. No patient died or was hospitalized, but approximately 50% had evidence of lower respiratory tract involvement. The average illness lasted 14 days. During the same period, 113 staff developed 338 respiratory illnesses. Eight percent were identified as Coronavirus and 9% as rhinovirus. Cough, sputum production, and constitutional symptoms were significantly more common among older persons.

CONCLUSIONS: Rhinovirus and Coronavirus 229E are common causes of moderately debilitating acute respiratory illnesses among older persons attending daycare.

<![CDATA[Pleomorphic, Enveloped, Virus-Like Particles Associated with Gastrointestinal Illness in Neonates]]> https://www.researchpad.co/article/Nc38f2de7-e1d2-4ce9-bec4-4d81f013c381

Abstract

Pleomorphic, enveloped, virus-like particles were detected by electron microscopy in the stools of symptomatic infants during an outbreak of gastrointestinal illness in a neonatal intensive-care unit. To determine the incidence of virus-like particles in the stool and their relation to gastrointestinal symptoms, eight surveys of stools for the particles were conducted over 40 weeks. The incidence of virus-like particles in the stool decreased from 69% to <10% over the study period. Most infants surveyed were premature; overall, 32 (36%) of 88 neonates were positive for virus-like particles. Statistically significant associations were found between virus-like particles in the stool and gastrointestinal symptoms within one week of each survey. These symptoms included water-loss stools, blood in the stool, gastric retention, bilious gastric aspirates, and abdominal distention. Several infants with virus-like particles whose mothers had gastrointestinal or “flu-like” symptoms before delivery were identified in the community (not part of the survey study).

<![CDATA[Infections with Legionella pneumophila in Children]]> https://www.researchpad.co/article/N531d4531-a31b-4be4-b7f3-cedd673f2b45

Abstract

To learn the role of Legionella pneumophila, the agent of Legionnaires' disease, in childhood illness, a prospective study was conducted among 52 children younger than four years of age with acute disease of the lower respiratory tract. Viral, mycoplasmal, and bacterial cultures and acute- and convalescent-phase sera were obtained during 64 episodes of acute illness; additional sera were drawn annually for three to five years. On the basis of serologic evidence, none of the acute episodes appeared to be due to L. pneumophila serogroup 1 or 2. However, examination of annual serum specimens showed that 27 (52%) of the children had rises in titer of indirect immunofluorescent antibody (a fourfold or greater rise to a reciprocal titer of ⩾128). Most rises in titer were in response to the serogroup 2 antigen. These results suggest that L. pneumophila is not a common cause of acute respiratory disease in early childhood in the study area but that children are frequently exposed to the organism. Alternatively, the serologic responses might be to unrelated cross-reacting microorganisms.

<![CDATA[A Prospective Study of Rotavirus Infection in Infants and Young Children]]> https://www.researchpad.co/article/Nf98010f9-a561-4ce7-a13e-9ace7d9a899f

Abstract

Diarrhea in neonates, followed as a cohort, and their families wasstudied prospectively. The families were followed for an average of 16.3 months. Stool and serum specimens were obtained at least every three months. Stool specimens were examined for viruses by electron microscopy and cultured for enteropathogens, and serum specimens were tested for antibodies to rotavirus and Norwalkvirus. During the study, 237episodes of gastroenteritis were observed in 104 infants and their 62 siblings. Rotavirus, detected 82 timesin 72 children, wasby far the most common enteropathogen. It was associated with gastrointestinal symptoms in 72% (with diarrhea in 65%). Rotavirus diarrhea occurred mostly in winter months and was significantly more frequently associated with respiratory symptoms than were diarrheas with other etiologies. Rotavirus infection was uncommon in the first six months of life, but by two years of age, 62% of the infants had had at least one infection. Neither breast feeding nor the presence of antibody to rotavirus in cord blood appeared to be protective.

<![CDATA[Utility of Coil-Assisted Retrograde Transvenous Obliteration II (CARTO-II) for the Treatment of Gastric Varices]]> https://www.researchpad.co/article/N43c43254-6089-4861-b929-a85edf4af577

Purpose

To investigate the technical feasibility, safety and clinical outcomes of coil-assisted retrograde transvenous obliteration II (CARTO-II) for gastric varices (GV).

Materials and Methods

Thirty-six consecutive patients who had undergone CARTO-II between June 2016 and April 2018 were included in the study. In the CARTO procedure, coil embolization of the drainage vein is performed “before” injection of the sclerosant to replace the use of balloon catheter. In the CARTO-II procedure, coil embolization of the drainage vein was performed “after” injection of the sclerosant to prevent migration of the sclerosant. CARTO-II was performed with ethanolamine oleate iopamidol, and the balloon catheter was immediately removed after coil placement. Technical and clinical success rates, number of coils used, presence or absence of severe complications, timing of the procedure, and rate of GV recurrence after the procedure were analyzed retrospectively.

Results

In all patients, GV sclerosis, coil placement and removal of the balloon catheter were successfully completed. The technical success rate was 100%. No patients experienced severe complications such as coil migration or pulmonary embolization. The mean number of metallic coils used per procedure was 3.36. Mean length of the procedure was 132.8 min. Contrast-enhanced computed tomography after CARTO-II confirmed complete variceal thrombosis in all cases. The recurrence rate of GV during follow-up was 2.8% (mean follow-up, 207 days).

Conclusion

CARTO-II was feasible and safe and could be performed relatively quickly. The number of coils used and the rate of GV recurrence were both low. CARTO-II may have an important role to play in the management of GV.

<![CDATA[Effect of using magnifying loupe glasses on lymphocele formation and surgical outcomes in gynecologic oncology]]> https://www.researchpad.co/article/Ne3b6b268-51fc-4b55-872e-ae8eefe2feef

Objective:

To investigate the effect of using magnifying loupes during surgery on surgical outcomes and lymphocele formation.

Materials and Methods:

We prospectively enrolled 36 patients with gynecologic cancer who underwent pelvic and para-aortic lymphadenectomy. Age, body mass index, menopausal status, type of cancer, comorbid diseases, preoperative albumin and albumin replacement therapy, performance status, serum CA125, hemoglobin, platelets and white blood cells, surgical procedure, blood loss, blood transfusion, the count of removed lymph nodes, presence of metastatic lymph nodes, total amount of drainage, postoperative complications, operation length, and count of used hemoclips were recorded. Patients were randomized into two groups: group 1 operated using loupe glasses, and group 2, without loupes.

Results:

In the loupe-negative group, total drainage volume was 6698 mL, whereas in the loupe-positive group, it was only 1049 mL (p<0.01). Postoperatively, the mean drainage duration was 10.6±5.1 days in loupe-negative group and 4.8±2.4 days in the loupe-positive group (p=0.0001). There were no differences between the two groups in terms of surgical site infections, fascial defects, and pulmonary thromboembolism (p=0.39, 0.33, 0.59, respectively). There was no significant difference in the number of harvested lymph nodes in patients who underwent surgery with or without loupes being used. The count of used hemoclips were 50.22±8.05 and 41.38±9.7 for the loupe-negative and positive groups, respectively (p<0.01). There was no lymphocele in the loupe-positive group, but we detected 5 (27.8%) lymphocele in the loupe-negative group (p=0.05).

Conclusion:

Gynecologic oncologic surgeons can add magnifying loupe glasses to their armament and benefit from this technical device; lymphocele development, total drainage volume, length of drainage time, and clip counts can be decreased by using loupe glasses in gynecologic cancer surgery.

<![CDATA[Cervix human papilloma virus positivity: Does it cause sexual dysfunction?]]> https://www.researchpad.co/article/Na5c4ce9b-398c-4ee5-9fd5-c4b83eb899c8

Objective:

To investigate whether testing positive for human papilloma virus (HPV) in cervical screening has an impact on female sexual functioning.

Materials and Methods:

This study was designed as a single-center, prospective, descriptive-cross-sectional study and 300 women who received HPV testing in our hospital [HPV-positive (n=187) or HPV-negative (n=113)]. The Arizona Sexual Experiences (ASEX) scale and Female Sexual Functioning index (FSFI) were administered to study participants during face-to-face interviews.

Results:

No significant differences were found between women who were HPV-positive and HPV-negative in sexual functions as assessed using the ASEX and FSFI scales (p=0.343 and p=0.604, respectively). In addition, the analyses addressing whether sexual functioning was affected by a positive test result, at diagnosis or during the follow-up (before 2 weeks, 2 weeks-1 month, 1-3 months, 3-6 months, 6 months-1 year and over 1 year) revealed no significant differences between HPV-positive and HPV-negative women in sexual functioning (p>0.05). Sexual dysfunction was less common in married women than in the ASEX scale (p=0.03), and this difference was not detected when the FSFI scale was applied. The incidence of dysfunction was more frequent in working women than in retirees (p=0.006, p=0.01).

Conclusion:

Educational attainment, socioeconomic status, age, employment status, and marital status were found to have statistically significant effects on sexual functioning. Sexual functioning was affected by neither HPV test results (positive/negative) nor time from diagnosis.

Objective:

To present the clinical, surgical, and pathologic features of bone recurrence in patients who underwent radical hysterectomy for early-stage uterine cervical cancer.

Materials and Methods:

Data of 412 patients who underwent type III radical hysterectomy and pelvic ± paraaortic lymphadenectomy for stage 1B-2A epithelial cervical cancer were reviewed. Seven (1.7%) patients with bone recurrence in the first recurrence were included in the study.

Results:

The median follow-up of the main cohort (n=412) was 46 (range=1-300) months. In this period, recurrence developed in 53 (12.9%) patients and recurrence was observed in bone in 13.2% (7 of 53) of these recurrences. Time to recurrence ranged from 9 to 45 months. Of the recurrences, five were in the axial skeleton and two were in the appendicular skeleton. Recurrence was observed in lumbar vertebrae in three patients, thoracic vertebrae in one patient, sacral vertebrae in one patient, lumbosacral vertebrae in one patient, and the left femur in two patients. Four patients had multiple recurrence in 3 patients despite isolated bone recurrence. Patients with multiple recurrences died within 6-25 months. All isolated bone recurrences were in the axial skeleton. Complete clinical response with salvage therapy was achieved in two patients with isolated bone recurrence.

Conclusion:

Complete clinical response and long postoperative survival can be achieved with salvage treatment when bone recurrence is solitary in cervical cancers.

<![CDATA[Radioembolization with 90Y Resin Microspheres of Neuroendocrine Liver Metastases After Initial Peptide Receptor Radionuclide Therapy]]> https://www.researchpad.co/article/N37cda71a-2747-48c1-bdff-23cb098379ba

Purpose

Peptide receptor radionuclide therapy (PRRT) and radioembolization are increasingly used in neuroendocrine neoplasms patients. However, concerns have been raised on cumulative hepatotoxicity. The aim of this sub-analysis was to investigate hepatotoxicity of yttrium-90 resin microspheres radioembolization in patients who were previously treated with PRRT.

Methods

Patients treated with radioembolization after systemic radionuclide treatment were retrospectively analysed. Imaging response according to response evaluation criteria in solid tumours (RECIST) v1.1 and clinical response after 3 months were collected. Clinical, biochemical and haematological toxicities according to common terminology criteria for adverse events (CTCAE) v4.03 were also collected. Specifics on prior PRRT, subsequent radioembolization treatments, treatments after radioembolization and overall survival (OS) were collected.

Results

Forty-four patients were included, who underwent a total of 58 radioembolization procedures, of which 55% whole liver treatments, at a median of 353 days after prior PRRT. According to RECIST 1.1, an objective response rate of 16% and disease control rate of 91% were found after 3 months. Clinical response was seen in 65% (15/23) of symptomatic patients after 3 months. Within 3 months, clinical toxicities occurred in 26%. Biochemical and haematological toxicities CTCAE grade 3–4 occurred in ≤ 10%, apart from lymphocytopenia (42%). Radioembolization-related complications occurred in 5% and fatal radioembolization-induced liver disease in 2% (one patient). A median OS of 3.5 years [95% confidence interval 1.8–5.1 years] after radioembolization for the entire study population was found.

Conclusion

Radioembolization after systemic radionuclide treatments is safe, and the occurrence of radioembolization-induced liver disease is rare.

Level of Evidence

<![CDATA[Evaluation of response to stereotactic radiosurgery in patients with radioresistant brain metastases]]> https://www.researchpad.co/article/N69500b5f-e37a-4083-a655-9cb5518b598e

Purpose

Renal cell carcinoma (RCC) and melanoma have been considered ‘radioresistant’ due to the fact that they do not respond to conventionally fractionated radiation therapy. Stereotactic radiosurgery (SRS) provides high-dose radiation to a defined target volume and a limited number of studies have suggested the potential effectiveness of SRS in radioresistant histologies. We sought to determine the effectiveness of SRS for the treatment of patients with radioresistant brain metastases.

Materials and Methods

We performed a retrospective review of our institutional database to identify patients with RCC or melanoma brain metastases treated with SRS. Treatment response were determined in accordance with the Response Evaluation Criteria in Solid Tumors.

Results

We identified 53 radioresistant brain metastases (28% RCC and 72% melanoma) treated in 18 patients. The mean target volume and coverage was 6.2 ± 9.5 mL and 95.5% ± 2.9%, respectively. The mean prescription dose was 20 ± 4.9 Gy. Forty lesions (75%) demonstrated a complete/partial response and 13 lesions (24%) with progressive/stable disease. Smaller target volume (p < 0.001), larger SRS dose (p < 0.001), and coverage (p = 0.008) were found to be positive predictors of complete response to SRS.

Conclusion

SRS is an effective management option with up to 75% response rate for radioresistant brain metastases. Tumor volume and radiation dose are predictors of response and can be used to guide the decision-making for patients with radioresistant brain metastases.

<![CDATA[Intensity-modulated radiotherapy for stage I glottic cancer: a short-term outcomes compared with three-dimensional conformal radiotherapy]]> https://www.researchpad.co/article/N5d80104b-a48a-4b91-a037-f48f3554e9df

Purpose

To investigate the differences in treatment outcomes between two radiation techniques, intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3DCRT).

Materials and Methods

We retrospectively analyzed 160 (IMRT = 23, 3DCRT = 137) patients with stage I glottic cancer treated from January 2005 through December 2016. The IMRT was performed with TomoTherapy (16 patients), volumetric-modulated arc therapy (6 patients), and step-and-shoot technique (1 patient), respectively. The 3DCRT was performed with bilateral parallel opposing fields. The median follow-up duration was 30 months (range, 31 to 42 months) in the IMRT group and 65 months (range, 20 to 143 months) in the 3DCRT group.

Results

The 5-year overall survival and 3-year local control rates of the 160 patients were 95.7% and 91.4%, respectively. There was no significant difference in 3-year local control rates between the IMRT and 3DCRT groups (94.4% vs. 91.0%; p = 0.587). Thirteen of 137 patients in the 3DCRT group had recurrences. In the IMRT group, one patient had a recurrence at the true vocal cord. Patients treated with IMRT had less grade 2 skin reaction than the 3DCRT group, but this had no statistical significance (4.3% vs. 21.2%; p = 0.080).

Conclusion

IMRT had comparable outcomes with 3DCRT, and a trend of less acute skin reaction in stage I glottic cancer patients
