RESUMO
We report and discuss a very rare case of early-stage rapidly progressive osteoarthritis (RPO) in a 33-year-old female athlete. The etiopathology of RPO remained unclear, although in this case mechanical overloading due to constant joint overuse appeared to be the only significant contributing factor to the very early development of RPO. Key words: rapidly progressive osteoarthritis, rapid destructive arthrosis, hip arthrosis, total hip arthroplasty, athlete, osteoarthritis.

OBJECTIVES: To compare the impact of clomiphene citrate (CC) vs other drug regimens on mid-cycle endometrial thickness (EMT), ovulation, pregnancy and live birth rates in women with World Health Organization (WHO) group II ovulatory disorders. METHODS: We searched MEDLINE, EMBASE, Scopus, Web of Science, The Cochrane Central Register of Clinical Trials (CENTRAL) and the non-MEDLINE subset of PubMed from inception to December 2016 and cross-checked references of relevant articles. We included only randomized controlled trials (RCTs) comparing CC used alone vs other drug regimens for ovulation induction in women with WHO group II anovulation. Outcomes were mid-cycle EMT, ovulation, pregnancy and live birth rates. We pooled weighted mean differences (WMD) with 95% confidence intervals (CI) for continuous variables (EMT) and risk ratios (RR) with 95% CI for binary variables (ovulation, pregnancy and live birth rates). RESULTS: We retrieved 1718 articles of which 33 RCTs (4349 women, 7210 ovulation induction cycles) were included. In 15 RCTs that compared CC with letrozole, EMT was lower in the CC group (1957 women, 3892 cycles; WMD, -1.39; 95% CI, -2.27 to -0.51; I2 = 100%), ovulation rates after CC and letrozole were comparable (1710 women, 3217 cycles; RR, 0.97; 95% CI, 0.90-1.04; I2 = 47%), while CC led to a lower pregnancy rate (1957 women, 3892 cycles; RR, 0.78; 95% CI, 0.63-0.95; I2 = 43%) and a lower live birth rate (RR, 0.70; 95% CI, 0.49-0.98; I2 = 35%). In two RCTs that compared CC with CC plus metformin, EMT, ovulation and pregnancy rates were comparable (101 women, 140 cycles; WMD, -0.23; 95% CI, -0.92 to 0.45; I2 = 78%; RR, 0.84; 95% CI, 0.67-1.06; I2 = 0%; and RR, 0.79; 95% CI, 0.33-1.87; I2 = 0%). In three studies that compared CC with CC plus N-acetyl cysteine (NAC), EMT was lower in the CC group (340 women, 300 cycles; WMD, -1.51; 95% CI, -1.98 to -1.04; I2 = 45%). In two studies that compared CC with CC + nitric oxide (NO) donor, EMT was lower in the CC group (120 women, 304 cycles; WMD, -1.75; 95% CI, -2.08 to -1.41; I2 = 0%). Compared with CC plus NO donor or NAC, CC showed statistically significant lower ovulation and pregnancy rates. Compared with tamoxifen in three studies, CC showed a tendency towards lower EMT (571 women, 844 cycles; WMD, -1.34; 95% CI, -2.70 to 0.01; I2 = 96%) with comparable ovulation and pregnancy rates. CONCLUSIONS: In women with WHO group II ovulatory disorders, ovulation induction with CC might result in lower EMT than other ovulation induction regimens. Whether the lower EMT caused the lower pregnancy and live birth rates remains to be elucidated. Letrozole seems to be beneficial for these women. However, our findings should be interpreted with caution as the quality of evidence was very low. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

OBJECTIVE: To report the intra-operative and post-operative results of laparoscopically assisted balloon vaginoplasty, a new technique for management of vaginal aplasia. METHODS: Eight women with vaginal aplasia due to Mullerian agenesis who were referred for apareunia, dyspareunia. All had a poor penetration score and sexual satisfaction score. A Foley's catheter was laparoscopically inserted in the space between the urethra and rectum. Gradual traction and distension were used to create a neovagina. Outcomes measured were intra-operative complications, post-operative complications, length of the neovagina and post-operative complications and sexual satisfaction score in both partners. RESULTS: Mean operative time was 25.5+/-5.5 min. No operative complications were recorded. Pain scores ranged from zero to 30 points at rest and from 30 to 60 points during dressing, traction and distension. Penetration and satisfaction scores increased significantly after the operation. CONCLUSIONS: Balloon vaginoplasty is a simple, safe and satisfactory technique for management of blind vagina.

OBJECTIVE: To investigate the effect of ω-3 fatty acids on amniotic fluid volume and uterine artery blood flow after 4 weeks of treatment. STUDY DESIGN: A randomized clinical trial was conducted on 140 participants with unexplained oligohydramnios at Woman's Health Hospital, Assiut University, Egypt. Participants were randomly assigned to ω-3 plus capsules or placebo. Categorical variables were analyzed by means of the χ2 test, whereas continuous variables were analyzed by means of the independent-sample T-test between the two groups. RESULTS: One hundred and forty women were recruited. There was significant improvement in the amniotic fluid index (AFI) in the ω-3 plus group in comparison with the placebo group (P=0.001). Moreover, there were significant decreases in the systolic/diastolic ratio (P=0.01), resistance index (P=0.041) and pulsatility index (P=0.002) of the uterine arteries in the ω-3 plus group when comparing baseline values with those after 4 weeks. CONCLUSION: The results suggest that ω-3 fatty acids may have a role in the increase in AFI in cases of unexplained oligohydramnios. This effect may be secondary to the increase in uterine blood flow.

BACKGROUND: Therapy of vertebral fractures in the elderly is a growing challenge for surgeons. Within the last two decades, the use of polymethylmethacrylate (PMMA) in the treatment of osteoporotic vertebral fractures has been widely established. Besides vertebroplasty and kyphoplasty, the augmentation of pedicle screws with PMMA found widespread use to strengthen the implant-bone interface. Several studies showed an enhanced pullout strength of augmented screws compared to standard pedicle screws in osteoporotic bone models. To validate the clinical relevance, we analyzed postoperative radiologic follow-up data in regard to secondary loss of correction and loosening of pedicle screws in elderly patients. MATERIALS AND METHODS: In this retrospective comparative study, 24 patients admitted to our level I trauma center were analyzed concerning screw loosening and secondary loss of correction following vertebral fracture and posterior instrumentation. Loss of correction was determined by the bisegmental Cobb angle and kyphosis angle of the fractured vertebra. Follow-up computed tomography (CT) scans were used to analyze the prevalence of clear zones around the pedicle screws as a sign of loosening. RESULTS: In 15 patients (mean age 76 ± 9.3 years) with 117 PMMA-augmented pedicle screws, 4.3 % of screws showed signs of loosening, whereas in nine patients (mean age 75 ± 8.2 years) with 86 uncemented screws, the loosening rate was 62.8 %. Thus, PMMA-augmented pedicle screws showed a significantly lower loosening rate compared to regular pedicle screws. Loss of correction was minimal, despite poor bone quality. There was significantly less loss of correction in patients with augmented pedicle screws (1.1° ± 0.8°) as compared to patients without augmentation (5° ± 3.8°). CONCLUSION: The reinforcement of pedicle screws using PMMA augmentation may be a viable option in the surgical treatment of spinal fractures in the elderly.
RESUMO
BACKGROUND: There are a variety of surgical strategies for the treatment of traumatic thoracolumbar vertebral fractures. There is still no proof for the superiority of any strategy concerning clinical or radiological outcomes. The aim of this study was the evaluation of residual complaints and correlation with radiological findings. PATIENTS AND METHODS: 87 patients, who underwent different types of surgery for vertebral fractures of the thoracolumbar region were included. Patients were treated by posterior stabilisation with internal fixation alone, by a combined approach using posterior internal fixation and anterior fusion by bone graft from the iliac crest with or without additional anterior plating or with a combined approach using posterior stabilisation and anterior implantation of an expandable titanium cage. Data were collected using results of physical examination, standardised testing of several established quality of life scores (SF-36, VAS, LBOS and Oswestry score) as well as radiological findings (post-traumatic kyphosis, loss of correction). RESULTS: There was no difference in the overall results of quality of life in the different subgroups. Analysis of the subgroups revealed differences in the complaints according to the surgical strategy used (a high rate of non-fusion where bone grafts, especially without additional anterior plating were used, combined with a high rate of bone graft morbidity, intercostal neuralgia in cage implantation). Loss of correction as documented in the radiological course showed a maximum in patients who underwent posterior stabilisation without an additional anterior approach. There was no correlation of loss of correction and quality of life. CONCLUSION: Overall outcomes of the four surgical strategies were comparable in our study concerning loss of correction and quality of life, respectively. The use of bone grafts, however, results in a high rate of non-fusion with a remarkable number of patients complaining about bone graft morbidity. Therefore we prefer the use of expandable titanium cages for anterior stabilisation if additional anterior stabilisation is necessary due to type of fracture or damage of adjacent discs. In any other cases, a limited approach by posterior instrumentation alone should be considered.

BACKGROUND: Within the last two decades the use of polymethylmethacrylate (PMMA) in the treatment of osteoporotic vertebral fractures has been established widely. Several techniques of cement application in spinal surgery have been described. Besides classical vertebroplasty, kyphoplasty and related techniques that reinforce stability of the fractured vertebral body itself, augmentation of pedicle screws became an issue in the past 10 years. Aim of this technique is strengthening of the implant-bone-interface and the prevention of loosening and failure of posterior instrumentation in limited bone quality due to osteoporosis. PMMA use in spinal surgery always bears the risk of cement leakage and cement embolism. There are only few publications dealing with cement leakage in pedicle screw augmentation. We examined our cohort concerning incidence and type of leakage in comparison to the literature. In particular, we evaluated a possible role of intrathoracic pressure during cementation procedure. PATIENTS AND METHODS: In this retrospective study 42 patients were included. Mean age was 74 (57-89) years. 311 fenestrated, augmented screws were analyzed postoperatively concerning leakage and subsequent pulmonary embolism of cement particles. Overall, there was a leakage rate of 38.3 %, and 28.6 % of patients showed pulmonary embolism of PMMA. During surgery, patients were in part ventilated with a positive end-expiratory pressure (PEEP) of 15 cmH2O during cement injection. These individuals showed significantly less leakage locally as well as less PMMA-emboli in the pulmonary circulation in contrast to patients ventilated without increased PEEP. CONCLUSION: PEEP elevation during administration of PMMA via fenestrated pedicle screws is reducing the leakage rate in spinal surgery. These beneficial effects warrant further evaluation in prospective studies.
RESUMO
PURPOSE: Although there are currently many different strategies and recommendations in the therapy of cervical spine fractures in elderly patients, there are still no generally accepted treatment algorithms. The aim of the present study was to analyze the morbidity, mortality, and outcome of operated cervical spine injuries in the elderly. METHODS: This study presents a retrospective review of 69 patients aged 65 years or older admitted to our level I trauma center with cervical spine injury, who had undergone surgical treatment. The data were acquired by analysis of the hospital inpatient enquiry system and radiological review. RESULTS: The ratio between male and female patients was 37:32. The average age of the patients was 76 years (ranging from 65 to 96 years) for males and 80 years (ranging from 66 to 93 years) for females. Injury to the cervical spine was caused by low-energy trauma in 71 % and high-energy trauma in 29 %, respectively. 55.1 % sustained isolated cervical spine injuries, 39.1 % injuries to two adjacent vertebrae, 2.9 % injuries to three adjacent vertebrae, and 2.9 % an odontoid fracture combined with associated fracture(s) in non-contiguous vertebra(e). Isolated spine injury level was dominated by C2 (47.8 %). The most common site for injuries to two adjacent vertebrae was observed at C6/C7 (14.5 %). The morbidity included cerebral complications, respiratory complications, Clostridium difficile-associated disease, heart failure, and acute renal failure. Operative complications included dislocation/malposition, neurovascular lesions, wound infection, and transient swallowing difficulty. The mortality rate at 3 months was 26.1 %, with an in-hospital mortality of 21.7 %. Age was associated with mortality at 3 months. A cervical fracture-induced neurological deficit was documented in 26.1 %, resulting in a mortality of 44.4 % (8/18). Twenty-seven of 33 patients living at home/nursing home at the time of injury returned to their home/nursing home after their hospitalization. The overall outcome was predominantly related to age and the severity of neurological deficit. CONCLUSIONS: In elderly patients with cervical spine fractures, the hospital course is complicated by medical issues and early mortality rates are significant. Therefore, treatment strategies should be carefully individualized to the patients and their comorbidities.

BACKGROUND: In our region we have noticed an increasing number of cyclists and consequently a rise in bicycle-related accidents in recent years. A large number of our polytraumatized patients are victims of bicycle-related accidents. MATERIAL AND METHODS: Retrospectively we analyzed the data of our polytraumatized patients recorded between May 2003 and June 2004 for bicycle-related injuries. Of 153 polytraumatized patients treated in our emergency room 32 were cyclists (21%). The average age of our polytraumatized cyclist was 42 years, and the male-to-female ratio was 1:1. RESULTS: The median score on the Glasgow Coma Scale (GCS) after the accident was 8 (min. 3, max. 15), the median Injury Severity Score (ISS) was 24 (min. 18, max. 41), and the median Polytrauma Score (PTS) was 23 (min. 14, max. 51). A total of 30 patients (94%) suffered a head injury; in 28 patients (88%) the head injury was the leading diagnosis. The median score on the Abbreviated Injury Scale (AIS) Head was 4 (min. 1, max. 5), the AIS Thorax 3 (min. 2, max. 4), and the AIS Extremities 3 (min, 2, max. 5). Our data were also compared with the official injury statistics of the region and the current literature. CONCLUSION: The most frequent and most severe injury was the head injury (94%). Of the 32 polytraumatized cyclists 30 did not wear a helmet. Successful prevention could possibly be practiced if all cyclists wear helmets.

BACKGROUND: Laparoscopic diagnosis of intestinal ischemia is difficult. Dark-colored bowels are not a reliable indicator for infarction, because there is no correlation between color and oxygenation. The same picture is produced by intraluminal blood or feces. False diagnoses are described. METHODS: We analyzed various techniques for assessing intestinal oxygenation and perfusion to support laparoscopic diagnosis. In this study laparoscopy was performed on eight pigs. A 10-cm segment of intestine was fixed to the abdominal wall and rendered ischemic. Measurements of the ischemic segment and normal intestine were taken using laser-Doppler, Doppler ultrasound, spectrophotometer, and pulse oximeter. Doppler ultrasound and pulse oximetry were unsuitable in our model, as was laser-Doppler flowmetry. RESULTS: Only the spectrophotometer proved a highly sensitive means of assessing bowel oxygenation. CONCLUSIONS: This method provides the desired additional information about intestinal oxygenation, thus helping to interpret the laparoscopic picture of dark bowels.
