Restoring bottom-up communication in brain-heart interplay after trauma-focused psychotherapy in breast cancer patients with post-traumatic stress disorder.

BACKGROUND: The psychological impact of breast cancer (BC) is substantial, with a significant number of patients (up to 32 %) experiencing post-traumatic stress disorder (PTSD). Exploring the emotional aspects of PTSD through the functional brain-heart interplay (BHI) offers valuable insights into the condition. BHI examines the functional interactions between cortical and sympathovagal dynamics. This study aims to investigate changes in functional directional BHI after trauma-focused (TF) psychotherapy, specifically Eye Movement Desensitization and Reprocessing (EMDR), in comparison to treatment as usual (TAU) among BC patients with PTSD. To our knowledge, this study represents the first examination of such changes. METHODS: We enrolled thirty BC patients who met the criteria for a PTSD diagnosis, with fourteen receiving EMDR and fifteen receiving TAU over a two- to three-month period. We analyzed changes in the emotional response during a script-driven imagery setting. Quantification of the functional interplay between EEG and sympathovagal dynamics was achieved using the synthetic data generation model (SDG) on electroencephalographic (EEG) and heartbeat series. Our focus was on the difference in the BHI index extracted at baseline and post-treatment. RESULTS: We found statistically significant higher coupling in the heart-to-brain direction in patients treated with EMDR compared to controls. This suggests that the flow of information from the autonomic nervous system to the central nervous system is restored following EMDR-induced recovery from PTSD. Furthermore, we observed a significant correlation between improvements in PTSD symptoms and an increase in functional BHI after EMDR treatment. CONCLUSIONS: TF psychotherapy, particularly EMDR, appears to facilitate the restoration of the bottom-up flow of interoceptive information, which is dysfunctional in patients with PTSD. The application of BHI analysis to the study of PTSD not only aids in identifying biomarkers of the disorder but also enhances our understanding of the changes brought about by TF treatments.

Identification of extraocular extension in uveal melanoma by ophthalmological ultrasound.

BACKGROUND AND PURPOSE: Uveal melanoma is the most common primary malignant intraocular tumour in the adult population, with a survival rate of 50% despite advances in treatment and knowledge of this disease. The presence of extraocular extension (EE) worsens the prognosis of these patients, so its proper identification can ensure its management and early intervention. Ophthalmological ultrasound is the technique of choice for the diagnosis and follow-up of these patients, both of the anterior EE using ultrasonic biomicroscopy (UBM), and the posterior EE using A and B ultrasound. The aim of this study is to describe the ultrasound characteristics of the BMU and the A and B ultrasound. MATERIAL AND METHODS: A descriptive and retrospective study is carried out on patients diagnosed with uveal melanoma (UM) and EE from 2003 to 2019. The ultrasound characteristics of the local disease and the follow-up after treatment were recorded completely and at each visit. In the case of anterior EE, photographs of the anterior segment and UBM were taken, while those involving the posterior segment were explored under A and B mode ultrasound. All enucleated eyes were sent for anatomopathological study. RESULTS: Ten patients with an average age of 72.3 years were included. The largest proportion of them were medium-sized tumours, followed by large and small ones. The most frequent morphology of the primary tumour was cupuliform. All the EE presented lower internal reflectivity compared to the primary tumour. No trans-scleral connection bridges were found between the primary tumour and the EE in the ultrasound studies. 50% of patients underwent primary enucleation at the time of diagnosis of intraocular MU due to the presence of the EE, and the remaining 50% presented the EE after initial treatment of the primary tumour with I125 brachytherapy. Sixty percent of the patients presented with posterior EE, and were therefore diagnosed with ultrasound A and B. The most frequent histopathological pattern with 87.5% of patients was the epithelioid pattern. DISCUSSION: Ultrasound scanning in patients with MU is mandatory for diagnosis and follow-up of EE. BMU and A and B ultrasound are the test of choice for anterior and posterior EE, respectively. EE have particular ultrasound characteristics such as low internal reflectivity, regularity of their contour and their location usually adjacent to the base of the primary intraocular tumor.

Clinical effectiveness of Lactobacillus reuteri in the treatment of peri-implant diseases: a systematic review and meta-analysis.

In the last decades, the presence of peri-implant diseases (PD) has increased. One of the therapies currently used is probiotics with Lactobacillus reuteri (LR). The aim of this article is to determinate, through a systematic review and meta-analysis, the clinical effectiveness of LR in the treatment of PD. We searched the literature until January 2021, in the biomedical databases: Pubmed, Embase, Scielo, Science Direct, Scopus, SIGLE, LILACS, Google Scholar and Cochrane Central Registry of Clinical Trials. The selection criteria of the studies were: randomized controlled clinical trials, without language and time restriction, reporting the clinical effects (depth to probing, plaque index and bleeding index) of the LR in the PD treatment. The risk of study bias was analyzed through the Cochrane tool for randomized studies using Review Manager software. The search strategy resulted in 6 articles of which four investigated peri-implantitis and three peri-implant mucositis. All studies reported that there was a difference in the depth of the probing in the treatment of PD, in favor of the group using LR, though not always achieving significance. The use of LR can be clinically effective in terms of pocket depth reduction in the treatment of PD.

Septoplasty: is it possible to identify potential "predictors" of surgical success?

Septoplasty is one of the most frequent surgical procedures performed by otolaryngologists. Despite successful surgical correction, many patients are not satisfied with their outcomes. So far, in clinical practice there is no consensus of opinion about the reliability of objective measurements of nasal patency and the correlation between objective measurements and subjective nasal patency symptoms. This study aims to assess the reasons for patient dissatisfaction after septoplasty and optimise pre-operative diagnostic management to predict surgical outcomes. We analysed 494 patients undergoing septoplasties with turbinoplasty by subjective Nasal Obstruction Symptom Evaluation questionnaire (NOSE) and objective active anterior rhinomanometric measurements before surgery and after 6 months. In our series, 17% had postoperative septal re-displacement; all patients had an anterior deviations at baseline. We found that the type of septal deviation, anterior vs posterior, was a significant predictor of postoperative functional improvement, whereas demographic characteristics as age, gender and smoke habit were not. Our data suggest that the anterior segment of the nasal septum was the most critical area for nasal airway resistance and more difficult to manage because it is likely to re-displace vs the posterior one and for this reason it represents a negative predictor of postoperative satisfaction.

A miRNA signature suggestive of nodal metastases from laryngeal carcinoma.

The discovery that miRNAs are frequently deregulated in tumours offers the opportunity to identify them as prognostic and diagnostic markers. The aim of this multicentric study is to identify a miRNA expression profile specific for laryngeal cancer. The secondary endpoint was to identify specific deregulated miRNAs with potential as prognostic biomarkers for tumour spread and nodal involvement, and specifically to search for a miRNA pattern pathognomonic for N+ laryngeal cancer and for N- tissues. We identified 20 miRNAs specific for laryngeal cancer and a tissue-specific miRNA signature that is predictive of lymph node metastases in laryngeal carcinoma characterised by 11 miRNAs, seven of which are overexpressed (upregulated) and four downregulated. These results allow the identification of a group of potential specific tumour biomarkers for laryngeal carcinoma that can be used to improve its diagnosis, particularly in early stages, as well as its prognosis.

Diagnostic performance of power doppler and ultrasound contrast agents in early imaging-based diagnosis of organ-confined prostate cancer: Is it possible to spare cores with contrast-guided biopsy?

OBJECTIVES: To evaluate the diagnostic performance of gray scale transrectal ultrasound-B-mode US (BMUS), power Doppler (PDUS), and sonographic contrast (CEUS) in early imaging-based diagnosis of localized prostate cancer (PCa) and to compare the diagnostic profitability of randomized biopsy (RB), US-targeted prostate biopsy by means of PDUS and CEUS. MATERIAL AND METHODS: A single-center, prospective, transversal, epidemiological study was conducted from January 2010 to January 2014. We consecutively included patients who an imaging study of the prostate with BMUS, PDUS, and CEUS was performed, followed by prostate biopsy due to clinical suspicion of prostate cancer (PSA 4-20ng/mL and/or rectal exam suggestive of malignancy). The diagnostic performance of BMUS, PDUS, and CEUS was determined by calculating the Sensitivity (S), Specificity (Sp), Predictive values (PV), and diagnostic odds ratio (OR) of the diagnosis tests and, for these variables, in the population general and based on their clinical stage according to rectal exam (cT1 and cT2). PCa detection rates determined by means of a randomized 10-core biopsy scheme were compared with detection rates of CEUS-targeted (SonoVue) 2-core biopsies. RESULTS: Of the initial 984 patients, US contrast SonoVue was administered to 179 (18.2%). The PCa detection rate by organ of BMUS/PDUS in the global population was 38% versus 43% in the subpopulation with CEUS. The mean age of the patients was 64.3±7.01years (95% CI, 63.75-64.70); mean total PSA was 8.9±3.61ng/mL (95% CI, 8.67-9.13) and the mean prostate volume was 56.2±29cc (95% CI, 54.2-58.1). The detection rate by organ of targeted biopsy with BMUS, PDUS, and CEUS were as follows: Global population (10.6, 8.2, 24.5%), stage cT1 (5.6, 4.2, 16.4%), and stage cT2 (32.4, 22.3, 43.5%). Comparing the detection rates of the CEUS-targeted biopsy and randomized biopsy, the following results were obtained: Global population (24.5% vs. 41.8%), stage cT1 (16% vs. 35%), and stage cT2 (43.5% vs. 66.6%), with a p value<0.05. Following the "core-by-core" analysis, the detection rates by core of CEUS-targeted biopsy versus randomized biopsy were: Global population (16% vs. 13%), stage cT1 (30.3% vs. 28%), and stage cT2 (48% vs. 37%), with a p value>0.05. The NNT for CEUS-targeted biopsy was 83.3. CONCLUSIONS: The low sensitivity, specificity, positive predictive and negative predictive values of gray scale-B-mode, PDUS and CEUS represent scant diagnostic performance of these variables in prostate cancer detection. Prostate cancer detection rates yielded by randomized biopsy were superior than the detection rate of targeted biopsy using B-mode, PDUS and CEUS; as a result, randomized biopsy versus CEUS-targeted biopsies cannot be excluded from biopsy strategy plans for the diagnosis of prostate cancer.

However, a normal range for all parameters was possible to obtain...

The management of chronic rupture of the Achilles tendon: minimally invasive peroneus brevis tendon transfer.

We hypothesised that a minimally invasive peroneus brevis tendon transfer would be effective for the management of a chronic rupture of the Achilles tendon. In 17 patients (three women, 14 men) who underwent minimally invasive transfer and tenodesis of the peroneus brevis to the calcaneum, at a mean follow-up of 4.6 years (2 to 7) the modified Achilles tendon total rupture score (ATRS) was recorded and the maximum circumference of the calf of the operated and contralateral limbs was measured. The strength of isometric plantar flexion of the gastrocsoleus complex and of eversion of the ankle were measured bilaterally. Functional outcomes were classified according to the four-point Boyden scale. At the latest review, the mean maximum circumference of the calf of the operated limb was not significantly different from the pre-operative mean value, (41.4 cm, 32 to 50 vs 40.6 cm, 33 to 46; p = 0.45), and not significantly less than that of the contralateral limb (43.1 cm, 35 to 52; p = 0.16). The mean peak torque (244.6 N, 125 to 367) and the strength of eversion of the operated ankle (149.1 N, 65 to 240) were significantly lower (p < 0.01) than those of the contralateral limb (mean peak torque 289, 145 to 419; strength of eversion: 175.2, 71 to 280). The mean ATRS significantly improved from 58 pre-operatively (35 to 68) to 91 (75 to 97; 95% confidence interval 85.3 to 93.2) at the time of final review. Of 13 patients who practised sport at the time of injury, ten still undertook recreational activities. This procedure may be safely performed, is minimally invasive, and allows most patients to return to pre-injury sport and daily activities.

Safety and outcome of surgical debridement of insertional Achilles tendinopathy using a transverse (Cincinnati) incision.

This is a prospective analysis on 30 physically active individuals with a mean age of 48.9 years (35 to 64) with chronic insertional tendinopathy of the tendo Achillis. Using a transverse incision, the tendon was debrided and an osteotomy of the posterosuperior corner of the calcaneus was performed in all patients. At a minimum post-operative follow-up of three years, the Victorian Institute of Sports Assessment scale-Achilles tendon scores were significantly improved compared to the baseline status. In two patients a superficial infection of the wound developed which resolved on antibiotics. There were no other wound complications, no nerve related complications, and no secondary avulsions of the tendo Achillis. In all, 26 patients had returned to their pre-injury level of activity and the remaining four modified their sporting activity. At the last appointment, the mean pain threshold and the mean post-operative tenderness were also significantly improved from the baseline (p < 0.001). In patients with insertional tendo Achillis a transverse incision allows a wide exposure and adequate debridement of the tendo Achillis insertion, less soft-tissue injury from aggressive retraction and a safe osteotomy of the posterosuperior corner of the calcaneum.

Pelvic reconstruction after abdominoperineal resection: a pilot study using an absorbable synthetic prosthesis.

BACKGROUND: Abdominoperineal resection (APR) is not free of complications, in particular complications due to the occupation of the pelvis by the small bowel after surgery. A number of surgical techniques have been described to prevent the small bowel from entering and adhering to the pelvis (pelvic partition), but there is no agreement concerning their use. The aim of this study was to evaluate the feasibility, effectiveness and safety of using an absorbable synthetic prosthetic material for pelvic partitioning after APR. METHODS: A prospective non-randomised longitudinal pilot study was carried out on a series of 10 patients who underwent APR due to lower-third rectal cancer, in order to evaluate the feasibility, safety and efficacy of pelvic partitioning with an absorbable synthetic prosthetic material. RESULTS: In all the patients, it was possible to perform a radical resection and to install the prosthesis. After a mean follow-up of 9 months (range: 4-18 months), no abdominal or perineal complications were detected. One patient (10%) suffered chronic pelvic pain. CONCLUSIONS: Pelvic partition after APR of the rectum with an absorbable synthetic prosthesis is feasible, effective and safe.

Gene expression analysis in calcific tendinopathy of the rotator cuff.

We evaluated the expression of several genes involved in tissue remodelling and bone development in patients with calcific tendinopathy of the rotator cuff. Biopsies from calcified and non-calcified areas were obtained from 10 patients (8 women and 2 men; average age: 55 years; range: 40-68) with calcific tendinopathy of the rotator cuff. To evaluate the expression of selected genes, RNA extraction, cDNA synthesis and quantitative polymerase chain reaction (PCR) were performed. A significantly increased expression of tissue transglutaminase (tTG)2 and its substrate, osteopontin, was detected in the calcific areas compared to the levels observed in the normal tissue from the same subject with calcific tendinopathy, whereas a modest increase was observed for catepsin K. There was also a significant decrease in mRNA expression of Bone Morphogenetic Protein (BMP)4 and BMP6 in the calcific area. BMP-2, collagen V and vascular endothelial growth factor (VEGF) did not show significant differences. Collagen X and matrix metalloproteinase (MMP)-9 were not detectable. A variation in expression of these genes could be characteristic of this form tendinopathy, since an increased level of these genes has not been detected in other forms of tendon lesions.

[Pelvic reconstruction after abdominoperineal resection of the rectum]. / Reconstrucción pélvica tras amputación abdominoperineal del recto.

Despite the advances in the treatment of cancer of the rectum and the expansion of the multimodal therapeutic technique, abdominoperineal resection (APR) still needs to be performed as radical treatment in 20-30% of cases. APR of the rectum involves a significant morbidity, including intestinal obstruction and wound complications, with radiotherapy-induced enteritis being able to develop in 15% of cases subjected to post-operative radiotherapy. Furthermore, with the aim of improving local oncology results, an extended APR is recommended; a technique that requires a perineal reconstruction technique that allows a tension free closure in a previously radiated tissue and may prevent perineal hernias developing. The objective of this article is to review pelvic and perineal repair methods after APR due to cancer, with special attention to the new prosthetic repair techniques.

Combined heart and kidney transplantation: long-term analysis of renal function and major adverse events at 20 years.

BACKGROUND: Combined heart-kidney transplantation (HKTx) is an accepted therapeutic option for patients with end-stage heart disease associated with severely impaired renal function. We report our long-term follow-up with this combined procedure. PATIENTS AND METHODS: Between April 1989 to November 2009, nine patients underwent combined simultaneous (HKTx) at our center. Seven patients were males (mean age 45.2 +/- 10.12 years); seven patients were on dialysis at the time of transplantation. RESULTS: Surgical procedures were uneventful in all patients. One patient died in the intensive care unit 41 days after transplantation. During long-term follow-up, three patients died: one due to infection and multiorgan failure 148 months after HKTx, one due to a lung neoplasm after 6 years, and one, a cerebral stroke at 34 months after transplantation. Only one patient experience renal allograft failure secondary to hypertension and cyclosporine nephrotoxicity at 10 years after HKTx with the need for renal replacement therapy. Last estimated glomerular filtration rates of all other patients was 61.3 +/- 17.4 mL/min. CONCLUSIONS: In selected patients, with coexisting end-stage cardiac and renal failure, combined HKTx with an allograft from the same donor proved to give satisfactory short- and long-term results, with a low incidence of both cardiac and renal allograft complications.

[Retroperitoneal malignant fibrous histiocytoma with contiguous organs infiltration]. / Histiocitoma fibroso maligno retroperitoneal con infiltración de organos vecinos.

Retroperitoneal tumours are extremely rare neoplasms, most of them malignant. We described the case of a 48-year-old man with a large retroperitoneal mass detected during the study of a constitutional syndrome. The mass was treated surgerically and pathological diagnosis was malignant fibrous histiocytoma. Literature is reviewed and clinical features, histological findings, radiological techniques and therapeutic management are analyzed.

[Incidental renal cancer in young adults: clinical and histopathological findings]. / Cancer renal incidental en pacientes menores de 40 años: hallazgos clinicos e histopatológicos.

OBJECTIVE: to evaluate the clinical and pathological renal cancer (CR) characteristics in our series of tumours, analyzing its impact in the group of age less than 40 years. MATERIAL AND METHODS: We studied 294 patients with CR. The pathologic characteristics were analyzed and DNA ploidy pattern of the surgical pieces were done in 252 patients. The patients were divided in two groups based on age, greater or less to 40 years, well then clinical and pathologic characteristics were compared between. RESULTS: Of all patients, 26 of 294 patients (8,94%) were included in the young age group (less to 40 years). We did not found differences between both groups comparing stage, tumoral volume, treatment realized or DNA ploidy pattern, but in nuclear grade with more aggressive tumours in young people (p=0,0018), without differences in recurrence-free survival or actuarial disease specific survival rate. CONCLUSIONS: The findings in our study indicate that the natural history and outcome of the RC is similar in both older and younger patients. Therefore, in our opinion, the management of CR in young people should be established with independence of the age.

[Prostate biopsy strategies. A review of the literature]. / Estrategias para la biopsia de próstata. revisión de la literatura.

INTRODUCTION: In 1987 transrectal ultrasound was described like the technique for guiding prostate biopsy. Since that time different options of transrectal ultrasound guided prostate biopsy were described. MATERIAL AND METHODS: We did a reviewed of the different techniques and cores distribution in the prostate biopsy, also we describes the patient preparation and the most important complications. RESULTS: The majority of the reviewed showed an increase in the sensibility rates with the extended transrectal ultrasound guided prostate biopsies. These improvements generally are due to the most lateral zones. CONCLUSION: Until now, due to a great experience and a low complications rate, the transrectal ultrasound guided prostate biopsy strategy should be extended respect the classical sextant biopsy with cores from the most lateral zones of the prostate.

[Leiomyoma of renal pelvis]. / Leiomioma de pelvis renal.

Renal leiomyoma are uncommon mesenchymal tumours, which can arise from any organ of the genitourinary tract with smooth muscle cells. The diagnostic imaging techniques available can not differentiated easily leiomyoma from other malignant renal masses. Since preoperative diagnosis cannot be made, management usually involves radical nephrectomy as in the case described. After treatment, prognosis is excellent.
