Patent foramen ovale is a congenital heart disease, which represents 80% of atrial septal defects and consist of a remnant of fetal circulation that functions in post-natal conditions as a transient interatrial right-to-left shunt of variable magnitude. The PFO may be implicated in the pathogenesis of several medical conditions, such as cryptogenic stroke, cryptogenic left circulation thromboembolism, migraine syndromes, decompression sickness. The most frequent indication for PFO closure remains PFO-associated left circulation thromboembolism. In select patients, PFO closure reduces stroke recurrence in comparison with medical therapy after more than 3 years of follow-up on average, especially in patients with a high risk of recurrence. While in PFO-associated left circulation embolism there is now a conclusive evidence on the growing benefit of PFO closure in the long term, in many other clinical conditions the degree of certainty of the results of the studies is deceiving. In this paper we will review the benefit and risks that one can expect at long term from percutaneous PFO closure in different clinical pictures, in order to facilitate therapeutic decision making.

Paget's disease of bone (PDB) is a late-onset chronic progressive bone disease characterized by abnormal activation of osteoclasts that results in bone pain, deformities, and fractures. PDB is very rare in Asia. A subset of PDB patients have early onset and can develop malignant giant cell tumors (GCTs) of the bone (PDB/GCTs), which arise within Paget bone lesions; the result is a significantly higher mortality rate. SQSTM1, TNFRSF11A, OPG, VCP and HNRNPA2B1 have been identified as pathogenic genes of PDB, and ZNF687 is the only confirmed gene to date known to cause PDB/GCT. However, the molecular mechanism underlying PDB/GCT has not been fully elucidated. Here, we investigate an extended Chinese pedigree with 8 individuals affected by early-onset and polyostotic PDB, two of whom developed GCTs. We identified a heterozygous 4-bp deletion in the Profilin 1 (PFN1) gene (c.318_321delTGAC) by genetic linkage analysis and exome sequencing for the family. Sanger sequencing revealed another heterozygous 1-bp deletion in PFN1 (c.324_324delG) in a sporadic early-onset PDB/GCT patient, further proving its causative role. Interestingly, a heterozygous missense mutation of PFN1 (c.335 T > C) was identified in another PDB/GCT family, revealing that not only deletion but also missense mutations in PFN1 can cause PDB/GCT. Furthermore, we established a Pfn1-mutated mouse model (C57BL/6J mice) and successfully obtained Pagetic phenotypes in heterozygous mice, verifying loss of function of PFN1 as the cause of PDB/GCT development. In conclusion, our findings reveal mutations in PFN1 as the pathological mechanism in PDB/GCT, and we successfully established Pfn1-mutated mice as a suitable animal model for studying PDB-associated pathological mechanisms. The identification of PFN1 mutations has great diagnostic value for identifying PDB individuals predisposed toward developing GCTs.

Whether continuous thoracic epidural analgesia (TEA) and continuous paravertebral block (PVB) have similar analgesic effects in patients undergoing video-assisted thoracic surgery (VATS) lobectomy was compared in this study.

Pain sensitization may be one of the mechanisms contributing to chronic low back pain (CLBP).

Due to their mass occurrence in some environments and high aggressiveness, blackflies ( spp.) represent the most bothersome arthropods attacking humans. In this study, we describe the medical effects of blackfly infestations in humans in southeastern Poland. Local and systemic reactions to blackfly bites were monitored in 418 patients (61.24% of females and 38.76% of males) of medical centers. Only skin lesions at the site of the bites were found in 88.52% of the patients, whereas accompanying systemic reactions were diagnosed in 11.48%. The most common signs observed in the area of the bites were pruritus (94.74%), burning (55.02%), edema (44.02%), and erythema (40.91%). The skin lesions, which were most often grouped small papules and papular and purpuric lesions with a varied range, typically persisted for several days, or for several weeks in some patients. Statistical analyses confirmed that the persistence of the skin lesions did not depend on the sex of the patients and the number of blackfly infestations. The systemic reactions to the components of the blackfly saliva were manifested by headache, increased body temperature, arthralgia, lymphadenopathy, and menstrual disorders in the females. The patients were most often attacked simultaneously by many blackflies on exposed parts of the body, mainly the upper limb, lower limb, head, and neck areas. The investigations indicate that blackflies are an important etiological factor of dermatitis and other symptoms in humans; hence, they should be considered in clinical diagnosis.

(1) Background: Using new technologies to manage home exercise programmes is an approach that allows more patients to benefit from therapy. The objective of this study is to explore physical therapists' opinions of the efficacy and disadvantages of implementing a web-based telerehabilitation programme for treating chronic low back pain (CLBP). (2) Methods: Nineteen physical therapists from academic and healthcare fields in both the public and private sector participated in the qualitative study. Texts extracted from a transcript of semi-structured, individual, in-depth interviews with each consenting participant were analysed to obtain the participants' prevailing opinions. The interviews lasted approximately 40 min each. The participants' responses were recorded. (3) Results: The results suggest that telerehabilitation can only be successful if patients become actively involved in their own treatment. However, exercise programmes for LBP are not always adapted to patient preferences. New technologies allow physical therapists to provide their patients with the follow-up and remote contact they demand, but long-term adherence to treatment stems from knowledge of the exercises and the correct techniques employed by the patients themselves. (4) Conclusions: Physical therapists treating patients with chronic non-specific low back pain believe that new technologies can provide highly effective means of reaching a greater number of patients and achieving significant savings in healthcare costs, despite the limitations of a telerehabilitation approach in developing an appropriate and effective patient-based physiotherapy programme.

(1) Background: Modern medicine generates a great deal of information that stored in medical databases. Simultaneously, extracting useful knowledge and making scientific decisions for diagnosis and treatment of diseases becomes increasingly necessary. Headache disorders are the most prevalent of all the neurological conditions. Headaches have not only medical but also great socioeconomic significance. The aim of this research is to develop an intelligent system for diagnosing primary headache disorders. (2) Methods: This research applied various mathematical, statistical and artificial intelligence techniques, among which the most important are: Calinski-Harabasz index, Analytical Hierarchy Process, and Weighted Fuzzy C-means Clustering Algorithm. These methods, techniques and methodologies are used to create a hybrid intelligent system for diagnosing primary headache disorders. The proposed intelligent diagnostic system is tested with original real-world data set with different metrics. (3) Results: First at all, nine of 20 attributes – features from International Headache Society (IHS) criteria are selected, and then only five most important attributes from IHS criteria are selected. The calculation result based on the Calinski-Harabasz index value (178) for the optimal number of clusters is three, and they present three classes of headaches: (i) migraine, (ii) tension-type headaches (TTHs), and (iii) other primary headaches (OPHs). The proposed hybrid intelligent system shows the following quality metrics: Accuracy 75%; Precision 67% for migraine, 74% for TTHs, 86% for OPHs, and Average Precision 77%; Recall 86% for migraine, 73% for TTHs, 67% for OPHs, Average Recall 75%; F score 75% for migraine, 74% for TTHs, 75% for OPHs, and Average F score 75%. (4) Conclusions: The hybrid intelligent system presents qualitative and respectable experimental results. The implementation of existing diagnostics systems and the development of new diagnostics systems in medicine is necessary in order to help physicians make quality diagnosis and decide the best treatments for the patients.

Allergic rhinitis is a chronic inflammatory disease of the nasal mucosa, mediated by immunoglobulin E, affecting 1 in 6 individuals. The treatment aims at attaining symptomatic control with minimal side effects, a requirement for new alternative therapies, including phototherapy, as it has an immunosuppressive and immunomodulatory effect.

Mental illnesses are chronic conditions in which an individual will often experience recurrent outcomes such as hospitalization, symptomatic relapse or self-harm behaviours. Most clinical research in psychiatry considers only the first event, and does not analyze subsequent recurrent events. Methods exist to analyze recurrent events; however, these methods are underused in the psychiatric research literature. This review identifies that recurrent events can be analyzed using a time homogenous or time-to-recurrent-event (TTRE) framework. The TTRE framework is underutilized in psychiatric research; however, this framework allows for longitudinal observations that are more congruent with the chronic nature of psychiatric illness than typical first event analyses. There are several readily available statistical models using the TTRE framework extending the standard Cox proportional hazards model. Our decision tool outlines four aspects of a research question to consider when selecting a TTRE model: (1) importance of event timing, (2) explanatory vs predictive, (3) common vs event-specific hazard, and (4) correlation of events within an individual. Analyzing recurrent events in psychiatric research provides an opportunity to address research questions aimed at understanding the longitudinal course of a chronic condition. These approaches may provide novel insights into risk factors or interventions for psychiatric illness, and ultimately improved outcomes for these chronic conditions.

There is a considerable overlap of symptoms between chronic exertional compartment syndrome (CECS) of the anterior and lateral compartments of the lower leg and entrapment neuropathy of the superficial peroneal nerve (SPN). We describe a minimally invasive, single incision surgical technique for release of both the compartments and the SPN in the same setting. The operative technique involves a minimal anterolateral approach at the level where the SPN pierces the subcutaneous fascia.
