Chronic orchialgia is a vexing condition defined as chronic or intermittent scrotal pain lasting at least three months that significantly interferes with daily activities. There are currently no guidelines regarding the diagnosis and management of this condition despite it being the cause of 2.5-4.8% of urologic clinic visits. Men often present with chronic orchialgia in their mid to late 30s, although the condition can present at any age. A broad differential diagnosis of chronic orchialgia includes epididymitis, testicular torsion, tumors, obstruction, varicocele, epididymal cysts, hydrocele, iatrogenic injury following vasectomy or hernia repair, and referred pain from a variety of sources including mid-ureteral stone, indirect inguinal hernia, aortic or common iliac artery aneurysms, lower back disorders, interstitial cystitis, and nerve entrapment due to perineural fibrosis; approximately 25-50% of chronic orchialgia is idiopathic in nature...

Lysyl oxidases are credited with pathogenic roles in lung diseases, including cancer, fibrosis, pulmonary hypertension, congenital diaphragmatic hernia, and bronchopulmonary dysplasia (BPD). Lysyl oxidases facilitate the covalent intra- and inter-molecular cross-linking of collagen and elastin fibers, thereby imparting tensile strength to the extracellular matrix (ECM). Alternative ECM-independent roles have recently been proposed for lysyl oxidases, including regulation of growth factor signaling, chromatin remodeling, and transcriptional regulation; all of which impact cell phenotype...

Scleroderma is a systemic disease of collagen deposition resulting in fibrosis of small arteries and arterioles. It commonly affects the skin, lungs, and gastrointestinal tract. The most common site of GI tract involvement is the esophagus. We present the case report of a 44year old female with scleroderma esophagus and severe reflux which was successfully treated with robotic dor fundoplication. Because of the wide variety of symptoms with which this problem can present, a tailored approach taking into consideration the patient's symptomatology and findings during diagnostic work-up was implemented with good results...

A novel biodegradable chitin hernia patch was prepared by acetylation of chitosan fabric in our study. Physicochemical properties, cell compatibility and biodegradability of the chitin patch were quantified. Histopathological study of the functional experiment showed that this newly designed hernia patch promoted collagen deposition and neovascularization by significantly promoting the secretion of FGF1 and TGF-β1 in the early postoperative (P<0.01). Chitin patch caused less inflammation by inhibiting excessive expression of IL-6 and TNF-α when compared to the polypropylene mesh (P<0...

The current prevalence of postoperative chronic pain from hernioplasty procedures employing polymer mesh is close to 30%. Most of the researchers agree that oxidative stress, resulting from the release of oxidants and enzymes during acute inflammatory response, is a key factor in the development of posthernioplasty complications. This results in both the decrease of the biomechanical properties and stiffening of the polymer fibers of the mesh, leading to chronic pain. Moreover, enhanced activity of inflammatory cells can lead to an excessive deposition of connective tissue around the implant...

PURPOSE: To perform a synthesis of articles addressing the role of stretching on roots in the pathophysiology of radiculopathy. METHODS: Review of relevant articles on this topic available in the PubMed database. RESULTS: An intraoperative microscopy study of patients with sciatica showed that in all patients the hernia was adherent to the dura mater of nerve roots. During the SLR (Lasègue's) test, the limitation of nerve root movement occurs by periradicular adhesive tissue, and temporary ischemic changes in the nerve root induced by the root stretching cause transient conduction disturbances...

The rising use of endovascular techniques utilizing femoral artery access may increase the frequency with which surgeons face the challenge of hernia repair in reoperative groins-which may or may not include a vascular graft. We present a case where a vascular graft contributed to an acute presentation and complicated dissection, and review the literature. A 67-year-old man who had undergone prior endovascular aneurysm repair via open bilateral femoral artery access and concomitant prosthetic femorofemoral bypass, presented with an incarcerated, scrotal inguinal hernia...

The assessment of early pulmonary disease and its severity can be difficult in young children, as procedures such as spirometry cannot be performed on them. Computed tomography provides detailed structural images of the pulmonary parenchyma, but its major drawback is that the patient is exposed to ionizing radiation. In this context, magnetic resonance imaging (MRI) is a promising technique for the evaluation of pediatric lung disease, especially when serial imaging is needed. Traditionally, MRI played a small role in evaluating the pulmonary parenchyma...

BACKGROUND/AIM: Mesh hernioplasty is one of the most frequently performed procedures in the United States. Abdominal rigidity and chronic inflammation, among other factors, contribute to long-term complications including chronic pain, abdominal wall stiffness and fibrosis. Acute models do not replicate the chronic environment associated with most hernias, limiting the ability to improve products. The present study details development of a critical-size defect in rabbit abdominal wall for maturation into a chronic hernia to enable analysis of hernia repair devices in a realistic environment...

INTRODUCTION: The "open abdomen" expression widely used to define a full-thickness defect of the abdominal wall intentionally made in some situations like abdominal compartment syndrome, has been replaced by a newest one called "laparostomy". The definitive closure of an open abdomen with a giant full abdominal thickness defect remains a problem. CASE REPORT: We present a 67-year old male with a descompressive laparostomy treated with a greater omentum flap sutured hermetically with interrupted stitches at the edges of the muscle wall, reinforced with large mesh of polypropylene (PP) placed on-lay and sutured to the fascia by two concentric running sutures of polypropylene...

BACKGROUND AND OBJECTIVES: Hiatal hernias are repaired laparoscopically with increasing use of reinforcement material. Both synthetic and biologically derived materials reduce the recurrence rate compared to primary crural repair. Synthetic mesh introduces complications, such as mesh erosion, fibrosis, and infection. Urinary bladder matrix (UBM) represents a biologically derived material for use in hiatal hernia repair reinforcement with the potential to improve durability of repair without incurring the risks of other reinforcement materials...

Gastro-oesophageal reflux has long been suspected of implication in the genesis and progression of idiopathic pulmonary fibrosis (IPF). We hypothesised that hiatal hernia may be more frequent in IPF than in other interstitial lung disease (ILD), and that hiatal hernia may be associated with more severe clinical characteristics in IPF.We retrospectively compared the prevalence of hiatal hernia on computed tomographic (CT) scans in 79 patients with IPF and 103 patients with other ILD (17 scleroderma, 54 other connective tissue diseases and 32 chronic hypersensitivity pneumonitis)...

PURPOSE: Repair of inguinal hernia and hydrocele are one of the most common operations performed by surgeons. However, the exact biological mechanism responsible for the closure of processus vaginalis (PV) is not completely understood. Transforming growth factor beta 1 (TGF-β1) is a potent fibrogenic agent and probably stimulate fibrosis and disappearing of PV. METHODS: From September 2012 to December 2014, all boys from 1 to 5 years who were referred for surgery of hydrocele were divided into two groups of communicating (HC) or non-communicating hydrocele (HNC)...

Hernias are generally repaired using synthetic prostheses. Infection may already be present or develop during implantation. Based on the increasing resistance to antibiotics, and the well-known antimicrobial properties of silver (Ag), the possibility of coating hernia prostheses with a nanostructured layer containing Ag was explored. Prostheses (Clear Mesh Composite [CMC]) made up of two polypropylene layers (macroporous light mesh and thin transparent film) were tested with human mesothelial cells from omentum biopsies...

PURPOSE: Use of polypropylene mesh (PPM) in hernia repair is associated with tissue reactivity. We examined, in a rat model, a novel non-biodegradable hydrogel coated PPM which may allow for decreased inflammation and a decreased foreign body reaction. METHODS: Through a dorsal midline incision, a 2 cm × 2 cm section of PPM (either coated or uncoated) was placed on the fascial surface 1.5 cm from the incision on the dorsal wall of Sprague-Dawley rats. At 2 and 12 weeks after placement, the PPM and surrounding tissue were harvested...

Chronic occult aspiration of small droplets (microaspiration) due to gastroesophageal reflux disease (GERD) and/or hiatal hernia is postulated to be a contributing factor in the pathogenesis of idiopathic pulmonary fibrosis (IPF). Usual interstitial pneumonia (UIP) is the histopathologic correlate of IPF. We hypothesized that chronic microaspiration may manifest as prominent airway-centered fibroblastic foci (FFs) in IPF. UIP cases diagnosed by wedge biopsies over a 6-year period (2006-2011) were identified and scored (1-3) for the prominence of airway-centered FFs by 2 authors blinded for clinical history...

Lumbar disc herniation (LDH) is a common disease that induces back pain and radicular pain. The most efficient method for the treatment of lumbar disc herniation is still controversial. Spontaneous regression of LDH has been recognized with the advancement of radiological diagnostic tools and can explain the reason of spontaneous relief of symptoms without treatment. The proposed hypotheses are; dehydration, retraction of the disc to the hernia in the annulus fibrosis, enzymatic catabolism and phagocytosis...
