Adjuvant Hysterectomy

Objective: To determine the incidence of pathology-proven residual disease in adjuvant hysterectomy specimens in patients with cervical cancer, treated with chemoradiation therapy. Secondly, to assess a possible association for pathology-proven residual disease regarding the time between chemoradiation therapy and adjuvant hysterectomy. Additionally, the survival rate and complication rate were assessed. Methods: PubMed, EMBASE, and the Cochrane database were searched from inception up to 8 March 2021. Results: Of the 4601 screened articles, eleven studies were included. A total of 1205 patients were treated with chemoradiation therapy and adjuvant hysterectomy, ranging from three to twelve weeks after chemoradiation therapy. A total of 411 out of 1205 patients (34%) had pathology-proven residual disease in the adjuvant hysterectomy specimen. There was no association found in the time between chemoradiation therapy and adjuvant hysterectomy. Follow-up ranged from 2.4 to 245 months, during which 270 patients (22%) relapsed, and 298 patients (27%) were deceased. A total of 202 (35%) complications were registered in 578 patients. Conclusion: there is no association found in the time between chemoradiation therapy and residual disease on adjuvant hysterectomy specimens. The survival rates after chemoradiation therapy and adjuvant hysterectomy are suboptimal, while the risk of complications after adjuvant hysterectomy is high.

This study aimed to systematically assess the outcomes of intentional replantation (IR) of teeth and to determine the survival rate, success rate, and prognostic factors related to the treatment. A search was conducted for all relevant English language articles published from January 2000 to October 2017. The search terms included "intentional replantation" and "teeth" according to the inclusion criteria. The Methodological Index for Non-randomized Studies (MINORS) was used to assess the methodological quality of included studies. Twelve studies were identified as relevant for the systematic review. In total, 896 patients with 905 teeth were examined for intentional teeth replantation. The success rate was greater than 90% in four studies (33.33%) and between 70% and 80% in five studies. At short-term follow-up (<6 months), the survival rate was approximately 90%. At longer-term follow-up (>36 months), the survival rates of teeth were slightly reduced in four studies, and tended to be stable after 48 months. In conclusion, the long-term success and survival rate of IR are likely dependent upon short extraoral time, reduced pocket depth, type of tooth, type of root-end filling material, and the prevention of atraumatic tooth root damage.

Background: Cartilage lesions are a significant cause of morbidity and impaired knee function; however, cartilage repair procedures have failed to reproduce native cartilage to date. Thus, osteochondral allograft (OCA) transplantation represents a 1-step procedure to repair large chondral defects without the donor site morbidity of osteochondral autograft transplantation. Purpose: To perform a systematic review of clinical outcomes and failure rates after OCA transplantation in the knee at a minimum mean 2 years’ follow-up. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature regarding the existing evidence for clinical outcomes and failure rates of OCA transplantation in the knee joint was performed using the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, PubMed, and MEDLINE from studies published between 1980 and 2017. Inclusion criteria were as follows: clinical outcomes and failure rates of OCAs for the treatment of chondral defects in the knee joint, English language, mean follow-up of 2 years and minimum follow-up of 18 months, minimum study size of 20 patients, and human studies. The methodological quality of each study was assessed using a modified version of the Coleman methodology score. Results: The systematic search identified 19 studies with a total of 1036 patients. The mean 5-year survival rate across the studies included in this review was 86.7% (range, 64.1%-100.0%), while the mean 10-year survival rate was 78.7% (range, 39.0%-93.0%). The mean survival rate was 72.8% at 15 years (range, 55.8%-84.0%) and 67.5% at 20 years (range, 66.0%-69.0%). The weighted mean patient age was 31.5 years (range, 10-82 years), and the weighted mean follow-up was 8.7 years (range, 2-32 years). The following outcome measures showed significant improvement from preoperatively to postoperatively: d’Aubigné-Postel, International Knee Documentation Committee, Knee Society function, and Lysholm scores. The weighted mean reoperation rate was 30.2% (range, 0%-63%). The weighted mean failure rate was 18.2% (range, 0%-31%). Of note, revision cases, patellar lesions, and bipolar lesions demonstrated worse survival rates. Conclusion: Improved patient-reported outcomes can be expected after OCA transplantation, with a survival rate of 78.7% at 10 years. Revision cases, patellar lesions, and bipolar lesions were associated with worse survival rates; therefore, utilization of the most appropriate index cartilage restoration procedure and proper patient selection are key to improving results.

Adjuvant Hysterectomy

Aims: Chemoradiation (CRT) is the standard treatment for locally advanced cervical cancer (LACC). However part of the patients develop recurrence during the first year after treatment despite good visible effect at the first follow-up. The role of completion surgery after radiotherapy (RT) is still debated. A number of papers have showed that up to 60% of patients have residual tumor after CRT and RT. But such a surgery is not widely recommended because of increased morbidity of the treatment. The aim of this study was to assess the results of surgery after radiotherapy of LACC. Method: We retrospectively evaluated data on 86 patients with cervical cancer IB - IIIB stages (mostly stage IIB) who underwent surgery in different modalities after CRT and RT with good clinical response in our department in 2015-2018. Results: When small asymptomatic residual disease was detected early after radiotherapy radical hysterectomy was feasible in most of the cases. Patients with clinical manifestation of recurrence had very poor prognosis. Surgery of recurrent cervical cancer sufficiently deteriorates quality of life, even if possible. Conclusion: Thorough examination with adding MRI imaging after initial treatment of cervical cancer needed to identify patients who may benefit from adjuvant hysterectomy.

This retrospective study evaluated the survival rate of short, sandblasted acid-etched surfaced implants with 6 and 8 mm lengths with at least 120 days of follow-up. Data concerning patient, implant and surgery characteristics were retrieved from clinical records. Sandblasted and acid-etched (SLA)-surfaced tissue-level 6 mm (TL6) or 8 mm (TL8) implants or bone-level tapered 8 mm (BLT8) implants were used. Absolute and relative frequency distributions were calculated for qualitative variables and mean values and standard deviations for quantitative variables. A Cox regression model was performed to verify whether type, length and/or width influence the implant survival. The cumulative implant survival rate was assessed by time-to-event analyses (Kaplan–Meier estimator). In all, 513 patients with a mean age of 58.00 ± 12.44 years received 1008 dental implants with a mean follow-up of 21.57 ± 10.77 months. Most implants (78.17%) presented a 4.1 mm diameter, and the most frequent indication was a partially edentulous arch (44.15%). The most frequent locations were the posterior mandible (53.97%) and the posterior maxilla (31.55%). No significant differences were found in survival rates between groups of type, length and width of implant with the cumulative rate being 97.7% ± 0.5%. Within the limitations of this study, the evaluated short implants are a predictable option with high survival rates during the follow-up without statistical differences between the appraised types, lengths and widths.

Reduction Of Pain

Fibromyalgia can be clinically defined by widespread pain lasting for longer than 3 months with tenderness on palpation in 11 or more of 18 specified tender points. Many people with fibromyalgia are significantly disabled, and experience moderate to severe pain for many years, for which conventional analgesics are usually not effective. For these patients treatment options generally include antidepressants like tricyclic agents, serotonin and noradrenaline reuptake inhibitors, or anticonvulsants like pregabalin or gabapentin. Pregabalin is a drug licensed for the treatment of fibromyalgia in the United States of America, with a mechanism of action similar to gabapentin. This mode of action confers antiepileptic, analgesic, and anxiolytic effects. This Cochrane systematic review included 8 randomized, placebo-controlled trials with low risk of bias, which studied the effect of a daily dose of pregabalin for the treatment of moderate to severe pain in adult patients suffering from fibromyalgia. Of the main results of this systematic review we highlight the major effect that a daily dose of 300 to 600 mg of pregabalin had in the reduction of pain intensity over a follow-up period of 12 to 26 weeks, with tolerable adverse effects, for a minority of people with moderate to severe pain due to fibromyalgia. This paper aims to summarize and discuss the main results and conclusions of this systematic review, as well as its implications for the daily clinical practice.

Background: The aim of this systematic review was to evaluate the survival rates of immediately loaded implants after at least five years. Besides implant failure, the amount of marginal bone loss around implants and the complication type were assessed. Methods: The electronic search was undertaken on Medline, Scopus, and Cochrane Central Register of Controlled Trials using key terms such as: “immediate loading”, “immediate function”, “immediate restoration”, “immediate temporization”, “dental implants”, “fully edentulous patients”, “partially edentulous patients”. The search terms were combined using the Boolean operators AND, OR. The last electronic search was performed on 15 February 2018. Two authors independently screened the studies, extracted the data, and assessed the risk-of bias. The main outcomes recorded for each study were: implant and prosthesis success and survival, marginal bone level change, incidence and type of complications. Kaplan–Meier analysis was used to estimate cumulative survival rates. Results: Thirty-four prospective studies with at least five-year follow-up, published between 2007 and 2017 were included. A total of 5349 immediately loaded implants in 1738 patients were analyzed. The mean follow-up was 72.4 months (median 60 months, 95% confidence intervals (CI): 64.53, 80.25 months, range 60 to 147 months). The mean weighted implant survival was 97.4% (median 98.15%, 95% CI: 96.29%, 98.54%, range 83.80% to 100%). Cumulative survival rate of implants placed in the mandible was significantly higher than for the maxilla (p < 0.01). No significant difference in failure rate was found among the types of prosthesis employed (p = 0.27). The mean peri-implant bone level change at the end of the follow-up in each study ranged from 0.3 to 1.7 mm. Conclusion: Immediate loading of implants appears to have long-term predictability and success rate under well-defined circumstances.

Abstract Objectives To assess survival rates and frequency of complications for immature and mature autotransplanted teeth after at least 1 year in function. Materials and methods All consecutive patients who had undergone tooth autotransplantation between 2000 and 2018 were invited to a clinical and radiographic follow-up examination. First, survival rates were calculated on the basis of a phone inquiry. A clinical follow-up examination allowed for the calculation of the success rate, i.e., absence of any potentially adverse clinical and radiographic findings of the autotransplanted teeth. Moreover, the effect of demographic, dental, and surgical variables on survival/success was analyzed statistically. Results Thirty-eight teeth in 35 patients were transplanted during the study period. Three teeth in 3 patients were excluded due to missing records. All other patients were successfully contacted and interviewed by phone. Out of these 35 transplants, 32 were still in function, and 3 had been extracted, yielding a 91.4% survival probability after a median follow-up of 3.4 years. Of the 32 teeth qualifying for the success analysis, 20 (62.5%) showed absence of potentially adverse findings, while 3 (9.4%) required root canal treatment (RCT). Out of the 9 mature, root-end resected transplants, 4 exhibited ongoing pulp canal obliteration, all with a single root canal. Postoperative and potentially adverse findings or failures were found more frequently in the group of mature transplants (55.6%) than immature transplants (30.4%) and for molars (72.7%) than premolars (17.6%) or canines (25%). None of the potential predictors had a statistically significant effect on survival or success. Conclusion Autotransplanted teeth yielded a satisfying midterm survival rate regardless of their stage of development. An additional, extraoral root-end resection of mature transplants may lead to rates of revascularization and postoperative pulp canal obliteration higher than the data reported on unmodified mature transplants. Clinical relevance Extraoral root-end resection of mature teeth shows promising outcomes for transplants especially with a single root canal and uncomplicated root morphology.

Abstract STUDY QUESTION What technique can be used to successfully cryopreserve three or fewer ejaculated spermatozoa from cryptozoospermic men and is the physical and cognitive development of children born after this technique normal? SUMMARY ANSWER The modified cryopreservation method for three or fewer human spermatozoa from cryptozoospermic men showed a recovery rate above 95% and a survival rate just under 90%, and the physical and cognitive abilities of the children born after ICSI were comparable to those born after natural conception. WHAT IS KNOWN ALREADY Clinical outcomes of ICSI using cryptozoospermic men’s ejaculated spermatozoa are considered to be inferior to that using testicular spermatozoa from microsurgical testicular sperm extraction (Micro-TESE), possibly because the DNA fragmentation rate is higher in ejaculated spermatozoa than in testicular spermatozoa from Micro-TESE. STUDY DESIGN, SIZE, DURATION Evaluation of the efficiency of cryopreservation of three or fewer spermatozoa was conducted retrospectively at St. Mother Clinic. The physical and cognitive development of children born after this method was studied between 2011 and 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS This study included 28 cryptozoospermic men who had three or fewer morphologically normal and motile spermatozoa in their ejaculate after centrifugation and who preferred using cryopreserved spermatozoa to Micro-TESE. Control subjects were 31 cryptozoospermic patients using fresh spermatozoa from their ejaculates and 20 non-obstructive azoospermic patients with fewer than 10 spermatozoa obtained by TESE and vitrified. Clinical outcomes among three groups, vitrified spermatozoa from the ejaculate, fresh spermatozoa from the ejaculate and vitrified spermatozoa from the testis, were statistically analysed. For the 7-year follow up study of the 14 children born after ICSI using the ejaculated vitrified spermatozoa, the Japanese government-issued Boshi Kenko Techo (Mother-Child Handbook) and Kinder Infant Development Scale (KIDS scale) were used to determine whether their physical and cognitive development was comparable to that of naturally conceived children. MAIN RESULTS AND THE ROLE OF CHANCE Recovery and survival rates were 97.8% (510/521) and 87.1% (444/510) for vitrified spermatozoa from the ejaculate and 92.7% (152/164) and 60.5% (92/152) for vitrified spermatozoa from the testis. Clinical pregnancies (%), miscarriages (%) and live birth rates (%), respectively, among the three groups were as follows: vitrified spermatozoa from the ejaculate: 15(25.0), 2(13.3), 13(21.7); fresh spermatozoa from the ejaculate: 26(24.3), 5(19.2), 20(18.7); and vitrified spermatozoa from the testis: 3(16.7), 0(0.0), 3(16.7). Among the groups, there were no statistically significant differences except for the sperm survival rate and the oocyte fertilisation rate, which were lower for vitrified spermatozoa from the testis compared with vitrified spermatozoa from the ejaculate. The 7-year follow-up study showed that the physical and cognitive development of 14 children born after ICSI using vitrified ejaculated spermatozoa from the ejaculate was comparable to that of naturally conceived children. LIMITATIONS, REASONS FOR CAUTIONS The maximum number of spermatozoa to which this method can be applied successfully is about 10. When the number of aspirated spermatozoa is over 10, some of them change direction after colliding with each other inside the aspiration pipette and reach the mineral oil, and once this happens, they cannot be expelled out of the pipette. Even though we did not find evidence of DNA fragmentation, further studies with larger participant numbers and longer time periods are necessary. WIDER IMPLICATIONS OF THE FINDINGS This technique is very useful for the cryopreservation of very small numbers of testicular spermatozoa (fewer than 10) in order to avoid or reduce Micro-TESE interventions. STUDY FUNDING/COMPETING INTEREST(S) No external funding was received to undertake this study. There are no competing interests. TRIAL REGISTRATION NUMBER N/A
