ABSTRACT
Cryotherapy has demonstrated its efficacy in post-traumatic soft tissue pain, through its anti-inflammatory action. Its postoperative use has also been the topic of many studies and has now proved its efficacy in indications such as ligament or knee arthroplasty surgery. The aim of this study was to analyze the effect of cryotherapy on pain and analgesic consumption after wrist or base of the thumb surgery. We prospectively included 60 patients from March 2017 to May 2018. All these patients had undergone wrist or base of the thumb surgery involving a bone procedure. Thirty patients were managed with cryotherapy (the Handfreez® splint), 30 patients were included in the control group with conventional immobilization. The data collected included a visual analogue scale (VAS), and analgesic and non-steroidal anti-inflammatory drug (NSAID) consumption, both during the hospital stay and then at home for one week. The results from the two groups were compared. During the hospital stay, morphine consumption was significantly lower in the cryotherapy group (p = 0.04). At home, NSAID consumption was significantly lower in the cryotherapy group (p = 0.009). The VAS score was not significantly different between the two groups. In our study, we demonstrated the benefits of cryotherapy on consumption of analgesics and NSAIDs after bone surgery of the wrist or the base of the thumb.

BACKGROUND: Cryoballoon ablation is an effective procedure to treat atrial fibrillation (AF). However, AF recurrence rate at 1-year follow-up is approximately 20% despite improvements in ablation technique. AIM: To find factors predictive of AF recurrence following a first pulmonary vein isolation procedure using a second-generation cryoballoon (PVI-2CB). METHODS: This was an observational, retrospective, single-centre study. From June 2012 to April 2017, all patients who had a PVI-2CB procedure and a scheduled follow-up at Rouen University Hospital were included. The primary endpoint was atrial arrhythmia (AA) recurrence (e.g. AF, flutter or tachycardia), considering a blanking period of 2 months following the procedure. Secondary endpoints were procedural variables for each pulmonary vein (successful isolation, time to disconnection, total cryoballoon application time, number of cryoballoon applications, level of occlusion during cryoballoon application leading to successful disconnection and lowest temperature reached during successful cryoballoon application), occurrence of redo procedures, use of antiarrhythmic drugs and adverse events. RESULTS: The initial population consisted of 239 patients; six were excluded for lack of procedural variable data, giving an analysed population of 233 patients. The AA recurrence rate was 36.9% (mean follow-up 25±14 months). Mean time to AA recurrence was 10±12 months. No procedural variable was found to be predictive of AA recurrence. Only major left atrial enlargement (defined as diameter>50mm or left atrial area>30cm2 or left atrial volume>50mL/m2) was predictive (odds ratio 2.70, 95% confidence interval 1.54-4.72; P=0.001). Forty-one patients had redo procedures (17.6% of analysed population); in this subgroup, 75.6% had at least one pulmonary vein reconnected, mainly the right inferior pulmonary vein. CONCLUSIONS: At long-term follow-up, up to one-third of patients had AA recurrence after PVI-2CB. Important atrial remodelling was the only factor predictive of AA recurrence, whereas no procedural variable was found to be predictive.

The immunotherapy of cerebral glioblastoma has become a hot topic. Immune checkpoint blockade antibodies have progressively acquired a role in the management of malignant tumors. A multimodal approach using surgery, radiotherapy, chemotherapy in combination with immunotherapy represent a potent weapon against glioblastomas. In parallel, clinical applications of cryotherapy-freezing tumors based on repetition of rapid freeze-slow thaw cycle-for various cancers such as skin, lung, breast, esophagus, hepatic, kidney, prostate and bone tumors were developed. The future immunomodulatory approaches might be combined with brain tumors cryoablation to increase the cryoimmune response. The objective of this study was to analyze from the literature the relationship between cerebral cryosurgery and immunomodulation using PRISMA method. The animals' studies demonstrate the dendritic cells maturation and activation with the enhancement of antigen-presenting function after cryotherapy suggesting the potential usefulness of the association of cryotherapy and immunomodulator in the management of gliomas.

INTRODUCTION: Whole body cryotherapy is a new therapeutic for pain treatment. Cryotherapy is, so far, a controversial technique challenged for its efficacy and its security. CASE REPORT: This is the case of a 61-year-old woman suffering from a haemorrhagic cerebrovascular accident during a whole-body cryotherapy session. The patient was treated for a psoriatic arthritis and was in remission. The aetiological screening was negative. CONCLUSION: We hypothesize that the whole-body cryotherapy was responsible for this stroke.

Locoregional therapy for advanced or recurrent desmoid tumor is part of our therapeutic armamentarium. Radiation therapy at a dose of 56Gy is feasible and has led to favorable results despite limited prospective data available. Cryoablation is a novel, very promising technique that may be applied in the same clinical picture of advanced, progressing or recurrent disease, in the hands of trained teams. All these options have to be discussed in sarcoma tumor boards due to the rarity of the disease and the expertise needed.

OBJECTIVE: To determine the pejorative predictive factors on oncologic outcomes of percutaneous MR-guided whole gland prostate cancer cryoablation (CA). METHODS: Medical records of patients treated from 2009 to 2012, to assess medium-term oncologic outcomes, were reviewed. Prostate biopsies were performed in local recurrence suspicion (biochemical failure, MR follow-up failure). RESULTS: Among 18 patients, mean age of 72.6 (61-78), 2 (11 %) and 7 (38.9 %) biological and reported biopsy-proven local recurrence respectively with our initial technic of CA. Mean follow-up and recurrence were 56.3 (±21.7) and 20.7 (±13.9) months respectively. A previous treatment of prostate cancer (P=0.5), pre-treatment PSA (P=0.2), pre-treatment Gleason/ISUP score (P=0.4), nadir PSA post-CA (P=0.22) were not associated with recurrence. Bilateral positive cores appears as a pejorative predictive factor (P=0.04). However mean pre-treatment positive cores percentage, 25 (±16.5) in responding patients versus 40.7 (±25.2) in case of recurrence, and maximum percentage of cancer extent in each positive core, 10.6 (±9.3) in responding patients versus 18.7 (±16.5) in case of recurrence, seemed associated with local recurrence after prostate CA but our analysis wasn't able to find a difference (P=0.09 and P=0.3 respectively) due to a lack of power. CONCLUSION: Bilateral positive cores appears as a pejorative predictive factor. In our experience, important tumor volume seem to be a pejorative predictive factor for oncologic outcomes after PCA whereas treatment, PSA, Gleason/ISUP score, nadir PSA are not.

High-intensity interval training (HIIT) induces vascular adaptations that might be attenuated by postexercise cold-water immersion (CWI). Circulating angiogenic cells (CAC) participate in the vascular adaptations and circulating endothelial cells (CEC) indicate endothelial damage. CAC and CEC are involved in vascular adaptation. Therefore, the aim of the study was to investigate postexercise CWI during HIIT on CAC and CEC and on muscle angiogenesis-related molecules. Seventeen male subjects performed 13 HIIT sessions followed by 15 min of passive recovery (n = 9) or CWI at 10 °C (n = 8). HIIT comprised cycling (8-12 bouts, 90%-110% peak power). The first and the thirteenth sessions were similar (8 bouts at 90% of peak power). Venous blood was drawn before exercise (baseline) and after the recovery strategy (postrecovery) in the first (pretraining) and in the thirteenth (post-training) sessions. For CAC and CEC identification lymphocyte surface markers (CD133, CD34, and VEGFR2) were used. Vastus lateralis muscle biopsies were performed pre- and post-training for protein (p-eNOSser1177) and gene (VEGF and HIF-1) expression analysis related to angiogenesis. CAC was not affected by HIIT or postexercise CWI. Postexercise CWI increased acute and baseline CEC number. Angiogenic protein and genes were not differently modulated by post-CWI. HIIT followed by either recovery strategy did not alter CAC number. Postexercise CWI increased a marker of endothelial damage both acutely and chronically, suggesting that this postexercise recovery strategy might cause endothelial damage. Novelty HIIT followed by CWI did not alter CAC. HIIT followed by CWI increased CEC. Postexercise CWI might cause endothelial damage.

INTRODUCTION: Cyclodialysis is a rare condition that is difficult to manage. We present the case of a woman with a cyclodialysis complicated by chronic hypotony requiring two surgeries to achieve reattachment of the ciliary body. We also report the results of a review of the literature regarding the treatment of this condition. DESCRIPTION: This is a 46-year-old woman with history of trauma to the right eye. Examination revealed an intra-ocular pressure (IOP) of 7mmHg, a shallow anterior chamber and signs of chronic hypotony on fundus examination (vascular tortuosity, hypotony maculopathy) due to an extensive 360° cyclodialysis, confirmed by ultrasound biomicroscopy. Transcleral cryotherapy as a first-line approach did not achieve reattachment of the ciliary body. Secondary pars plana vitrectomy with gas tamponade (C2F6) reattached the ciliary body and restored the intraocular pressure (12mmHg) and normal fundus appearance. The patient recovered corrected visual acuity of 20/20. DISCUSSION: To our knowledge, there is no standardized management for cyclodialysis. The study of the literature available on the Medline database showed that direct cyclopexy remains the most common treatment, followed by vitrectomy with internal tamponade. Neither the extent nor the duration of the cyclodialysis can predict the visual recovery, which can be major even after weeks of hypotony. CONCLUSION: The management of cyclodialysis is not well-defined; it remains a true therapeutic challenge.

BACKGROUND: Chromomycosis is a chronic fungal skin infection, mainly affecting the limbs. It is responsible for severe morbidity and its treatment remains long and disappointing. Rarely described in Morocco, we report a new observation that has evolved very well under treatment combining terbinafine and cryotherapy over a short duration. CASE REPORT: A 56-year-old patient, immunocompetent, had a pustular and crusty placard on both forearms that had evolved for a year. Mycological examination showed fumagoid bodies and cutaneous biopsy showed epithelioid granulomas and giant cells without necrosis. The PCR confirmed a chromomycosis at Fonsecaea pedrosoi. HIV serology was negative. Treatment with terbinafine 250mg/d for 6months combined to cryotherapy resulted in complete remission with initial clinical improvement after only 3 weeks. DISCUSSION: Chromomycosis occurs increasingly in non-tropical areas. If diagnostic methods become more effective, management remains difficult and poorly codified. Terbinafine-cryotherapy combination would bring a lot of benefits with a little risk to bothpractitioner and patient. CONCLUSION: This combined treatment would constitute an excellent therapeutic alternative because of its efficiency, feasibility, low cost, method of administration and aesthetic result.

OBJECTIVE: To study the oncologic and functional results of salvage cryotherapy after failure of external radiotherapy and brachytherapy. MATERIALS AND METHODS: Patients treated by total salvage cryotherapy (3rd generation) in 2 centers (Groupe Hospitalier Saint-Joseph in Paris and Clinique Jule-Verne Nantes) in between January 2008 and April 2016 were included. The biochemical recurrence-free survival (BRFS) was calculated using the Phoenix criteria (PSA>nadir+2ng/mL). The functional results were assessed clinically. RESULTS: Ninety-seven patients with an average follow up of 39.4months were evaluated retrospectively. The 5-year biochemical recurrence-free survival (5y-BRFS) among all patients was 58.1% (IC à 95% [45.9-68.5]). Low and intermediate risk patients (d'Amico classification) were less prone to biochemical recurrence than high risk (81.05% (IC à 95% [64.1-90.5]) 5y-BRFS as opposed to 35.09% (IC à 95% [20.1-50.4]) respectively) (P<0.0001). As were patients with a Gleason score≤7 75.35% (IC à 95% [59.7-85.6]) compared to 32.31% (IC à 95% [16.5-49.2]) for higher Gleason (>7 scores [P=0.0002]). A Gleason score>7 (OR=6.9; P=0.002), PSA nadir>1ng/mL (OR=25.8; P=0.0026) and peri-urethral invasion (OR=35.8; P<0.001) were major risk factors for local recurrence in univariate analysis. In multivariate analysis, only PSA nadir>1ng/mL (OR=12.9; P=0.042) and peri-urethral invasion (OR=21.6; P=0.0003) remain major risk factors for recurrence. About 13 (16.46%) patients were incontinent of which 3 (3.79%) required placement of an artificial urinary sphincter. Erectile dysfunction was present in 66 (83.5%) patients. Recto-urethral fistula was uncommon in 1 patient (1.27%). CONCLUSION: Salvage cryotherapy after failure of external radiotherapy and brachytherapy is a reliable and reproducible technique with promising oncological and functional results. Study of prognostic factors will help better select eligible patients in the future. LEVEL OF EVIDENCE: 4.

INTRODUCTION: Retinal hemangioblastoma (RH) is a benign vascular tumor frequently associated with Von Hippel-Lindau disease (VHL). Tumor growth of RH may lead to deterioration of visual acuity, which can be difficult to treat. Early diagnosis may reduce complication rate and side effects of treatment. The present retrospective study evaluates the long-term follow-up and complications of RH treatment as a function of the therapeutic strategy used. MATERIALS AND METHODS: The study included patients with RH, followed at Croix Rousse university hospital, Lyon between 2010 and 2017. The following clinical features were recorded : age at diagnosis, presenting symptom, presence of VHL disease, treatments used, post-therapeutic complications and visual outcomes. RESULTS: Seven eyes of five patients were included in our study. Eighty percent of the patients had a mutation in the VHL gene. Four eyes (57%) were treated with laser photocoagulation and three eyes (43%) were treated with cryotherapy. The mean duration of follow-up was 35 months. One of the eyes treated using laser photocoagulation was complicated by an early epiretinal membrane with no visual consequence. Of the eyes treated by cryoapplication, one was complicated by a vitreous hemorrhage, and another by a rhegmatogenous retinal detachment, both of which resulted in a decrease in visual acuity. CONCLUSION: The long-term outcome for patients treated for RH was relatively good. Complications were strongly correlated with the initial size of the vascular tumor. Early diagnosis seems to improve visual outcomes. Ophthalmologic monitoring should be part of the systemic, multidisciplinary management.

INTRODUCTION: The incidence of kidney cancer has increased significantly over the past few decades presumably due to the increased use of imaging. The aim of this article is to describe contemporary outcomes of ablative therapy and to compare them to other therapeutic options in terms of oncological, functional, perioperative outcomes and cost. MATERIAL AND METHODS: We searched MEDLINE®, Embase®, using (MeSH) words; from January 2005 through May 2017, and we looked for all the studies. Investigators graded the strength of evidence in terms of methodology, language and relevance. RESULTS: Ninety-one articles were analyzed. We described the outcomes of ablative therapy in relation to the energy used and the approach, and compared these outcomes to the other therapeutic options in terms of oncological, functional and perioperative outcomes. We analyzed these studies in order to search for predictive factors influencing the results of ablative therapy. We also analyzed the economic burden of small renal tumor management. CONCLUSION: The strength of evidence is based almost entirely on retrospective studies and is susceptible to the inherent limitations of this study design. Although, the evidence was low among studies, our revue showed that, in elderly patients treated with ablative therapy for cT1a tumors, the cancer-specific survival was comparable to partial nephrectomy with differences in overall survival that are explained by competing risks of death in the old population. Considering the functional results, the renal function preservation seems to be comparable between the 2 groups while the perioperative morbidity is higher in the partial nephrectomy group. The evidence base medicine at this time cannot support the extension of the indications of ablative therapy beyond the actual implementations.

MATERIAL AND METHODS: We searched MEDLINE®, Embase®, using (MeSH) words; from January 2005 through May 2017, and we looked for all the studies. Investigators graded the strength of evidence in terms of methodology, language and relevance. RESULTS: Forty-seven articles were analyzed. We described ablative techniques and sorted them in thermal and non-thermal therapies according to the used physical principle and their frequency of use in the urological pathology. CONCLUSION: Percutaneous ablative therapies are mini-invasive techniques, which have an important role in tumors focal treatment. This article is a review of the ablative therapies and describes their physical principles, their equipment and their recent technological modifications, which have been developed to improve the clinical success of these techniques.

OBJECTIVES: Ablative treatment (AT) rise is foreseen, validation of steps to insure good proceedings is needed. By looking over the process of the patient, this study evaluates the requirements and choices needed in every step of the management. METHODS: We searched MEDLINE®, Embase®, using (MeSH) words and we looked for all the studies. Investigators graded the strength of evidence in terms of methodology, language and relevance. RESULTS: Explanations of AT proposal rather than partial nephrectomy or surveillance have to be discussed in a consultation shared by urologist and interventional radiologist. Per-procedure choices depend on predictable ballistic difficulties. High volume, proximity of the hilum or of a risky organ are in favor of general anesthesia, cryotherapy and computed tomography/magnetic resonance imaging (CT/MRI). Percutaneous approach should be privileged, as it seems as effective as the laparoscopic approach. Early and delayed complications have to be treated both by urologist and radiologist. Surveillance by CT/MRI insure of the lack of contrast-enhanced in the treated area. Patients and tumors criteria, in case of incomplete treatment or recurrence, are the key of the appropriate treatment: surgery, second session of AT, surveillance. CONCLUSION: AT treatments require patient's comprehension, excellent coordination of the partnership between urologist and radiologist and relevant choices during intervention.

BACKGROUND: Ablative therapies (AT) in kidney cancer are rising. It's important to evaluate the situation of this therapy. The aim of this study is to identify the best indications for AT treatment for kidney cancer. METHODS: Review of literature using Medline and Embase databases. Study were selected based on scientific relevance. Clinical keys centered on the best requirements to indicate ablative therapies. RESULTS: AT is indicated according to specific tumor and patients criteria. A good initial evaluation is essential (imaging, pathology, renal function and general condition of the patient). AT gets the best results when applied to the following tumor criteria: solid tumor, length<3cm, exophytic localization, RENAL score<8. In few cases, AT could be discussed as an alternative to the reference treatment, sparing surgery: life expectancy evaluated between 3 and 7 years, chronic renal failure or single kidney, transplanted kidney, familial tumors. AT can be used in first line, post-surgery after local recurrence or for distant metastasis. Like every other innovative technic, indications of AT would be adjust with learning curve and cost-effectiveness. CONCLUSION: AT have to be included as a valid treatment for kidney cancer<4cm. The respect of actual indications and collection of results of AT compared to surveillance and surgery, would determinate the evolution of AT indications in the future.

Percutaneous lung thermo-ablation has steadily been developed over the past 15years. Main indications are early stage non-small cell lung carcinoma (NSCLC) for non-surgical patients and slow evolving localized metastatic disease, either spontaneous or following a general treatment. Radiofrequency, being the most evaluated technique, offers a local control rate of about 80-90% for tumors <3 cm in diameter. With excellent tolerance and very few complications, radiofrequency may be proposed for patients with a chronic disease. Other ablation techniques under investigation such as microwaves and cryotherapy could allow overcoming radiofrequency limits. Furthermore, stereotactic radiotherapy proposed for the same indications is efficient. Comparative studies are warranted to differentiate these techniques in terms of efficacy, tolerance and cost-effectiveness.

Combative sport is one of the most physically intense forms of exercise, yet the effect of recovery interventions has been largely unexplored. We investigated the effect of cold-water immersion on structural, inflammatory, and physiological stress biomarkers following a mixed martial arts (MMA) contest preparation training session in comparison with passive recovery. Semiprofessional MMA competitors (n = 15) were randomly assigned to a cold-water immersion (15 min at 10 °C) or passive recovery protocol (ambient air) completed immediately following a contest preparation training session. Markers of muscle damage (urinary myoglobin), inflammation/oxidative stress (urinary neopterin + total neopterin (neopterin + 7,8-dihydroneopterin)), and hypothalamic-pituitary axis (HPA) activation (saliva cortisol) were determined before, immediately after, and 1, 2, and 24 h postsession. Ratings of perceived soreness and fatigue, counter movement jump, and gastrointestinal temperature were also measured. Concentrations of all biomarkers increased significantly (p < 0.05) postsession. Cold water immersion attenuated increases in urinary neopterin (p < 0.05, d = 0.58), total neopterin (p < 0.05, d = 0.89), and saliva cortisol after 2 h (p < 0.05, d = 0.68) and urinary neopterin again at 24 h (p < 0.01, d = 0.57) in comparison with passive recovery. Perceived soreness, fatigue, and gastrointestinal temperatures were also lower for the cold-water immersion group at several time points postsession whilst counter movement jump did not differ. Combative sport athletes who are subjected to impact-induced stress may benefit from immediate cold-water immersion as a simple recovery intervention that reduces delayed onset muscle soreness as well as macrophage and HPA activation whilst not impairing functional performance.

Keloids scars are a dysregulated response to cutaneous wound healing and can be associated with substantial physical and psychological distress. Unfortunately, they occur when surgical excision is performed. While the pathogenesis of keloids continues to be investigated, numerous treatment options exist. But there is still no ideal treatment. Their management needs association of treatment and long-term follow-up to observe and manage recurrence. In this second part, we propose a strategy for management of keloids scars.

BACKGROUND: Pulmonary vein (PV) isolation, using cryoballoon or radiofrequency ablation, is the cornerstone therapy for symptomatic paroxysmal atrial fibrillation (AF) refractory to antiarrhythmic drugs. One-third of the patients have recurrences, mainly due to PV reconnections. AIMS: To describe the different locations of reconnection sites in patients who had previously undergone radiofrequency or cryoballoon ablation, and to compare the characteristics of the redo procedures in both instances. METHODS: Demographic data and characteristics of the initial ablation (cryoballoon or radiofrequency) were collected. Number and localization of reconduction gaps, and redo characteristics were reviewed. RESULTS: Seventy-four patients scheduled for a redo ablation of paroxysmal AF were included; 38 had been treated by radiofrequency ablation and 36 by cryoballoon ablation during the first procedure. For the initial ablation, procedural and fluoroscopy times were significantly shorter for cryoballoon ablation (147.8±52.6min vs. 226.6±64.3min [P<0.001] and 37.0±17.7min vs. 50.8±22.7min [P=0.005], respectively). Overall, an identical number of gaps was found during redo procedures of cryoballoon and radiofrequency ablations. However, a significantly higher number of gaps were located in the right superior PV for patients first ablated with radiofrequency (0.9±1.0 vs. 0.5±0.9; P=0.009). Gap localization displayed different patterns. Although not significant, redo procedures of cryoballoon ablation were slightly shorter and needed shorter durations of radiofrequency to achieve PV isolation. CONCLUSIONS: During redo procedures, gap localization pattern is different for patients first ablated with cryoballoon or radiofrequency ablation, and right superior PV reconnections occur more frequently after radiofrequency ablation. Redo ablation of a previous cryoballoon ablation appears to be easier.

OBJECTIVES: To assess the impact of smear test in the fight against cervix uteri cancer in Senegal. METHODS: This was a descriptive cross-sectional study of 1836 Pap smears performed in patients over 15 years during several screening campaigns in Senegal conducted between June 2010 and June 2012. We analyzed epidemiological data, pathological smears, and the proposed management. RESULTS: In 69% of cases, the women were less than 45 years old. They were mostly multiparous and did not use contraceptive methods before. The smears were interpreted in 91.4% (n=1661) and were pathological in 5.2% of cases. They revealed mainly atypical squamous cells of undetermined significance, squamous intraepithelial low-grade lesions, and squamous intraepithelial high-grade lesions, respectively in 2.5% (n=46), 1.7% (n=30) and 1% (n=19) of cases. Multiparity, early marriages were the main risk factors. Patients with pathological smars had colposcopy with cryotherapy (23 cases), and colposcopy and biopsy (13 cases). A hysterectomy was performed in 4 cases. CONCLUSION: The pathological smear rate found in this study confirms the interest to continue cervical cancer screening with this practice. Strengthening of its geographical and financial access through a national prevention program will effectively help to lower cases of cervical cancer.
