Pancreatitis is an inflammation of the pancreas that can progress from an acute presentation to an acute recurring presentation and eventually to chronic pancreatitis, which is characterized by irreversible morphological changes and scarring of the pancreas. The entity known as hereditary pancreatitis has been recognized in the literature for years and certainly the discovery of the PRSS1 gene in 1996 marked the beginning of a new era of genetic discoveries associated with the disease. Since then, multiple genes have been described as the causing agents of pancreatitis or disease modifiers, some of the most important ones being the PRSS1, SPINK1, CFTR, CASR, CTRC, CLDN2, and CPA1...

PURPOSE: Tube exposure remains one of the most common complications after glaucoma drainage device (GDD) implantation, despite various types of patch grafts available today. We present a 4 patient case series following the effectivity of the keratolimbal allograft (KLAL) as a patch graft for cases of tube exposure. Given its inherent population of stem cells, our hypothesis was that this highly replicative, biological tissue would provide an adequate means of glaucoma tube coverage. The subset of patients chosen for the KLAL patch graft all had a history of abnormally scarred conjunctiva or thin sclera...

It has been suggested that the predilection of sarcoidosis to affect scars is due to the presence of antigens or foreign bodies that can serve as a stimulus for granuloma formation. Several patients with sarcoidosis-specific skin lesions in venous puncture sites have been reported. However, in these patients the pathogenesis of the cutaneous lesions is not clear because the presence of foreign bodies is not to be expected. Our objective was to describe 3 patients who developed specific lesions of sarcoidosis in areas of venipuncture and to discuss their possible pathogenesis...

INTRODUCTION: The right atrium (RA) is readily accessible; however, it is unclear whether changes in the RA are representative of the LA. We performed detailed bi-atrial electroanatomic mapping to determine the electrophysiological relationship between the atria. METHODS AND RESULTS: Consecutive patients with persistent AF underwent bi-atrial electroanatomical mapping with a contact force catheter acquiring points with a CF > 10 g prior to ablation. Points were analyzed for tissue voltage, complex electrograms, low voltage (< 0...

Currently, immediate loading of dental implants is very attractive as a standard protocol for prosthetic restorations in edentulous patients. The aim of this study is to find out the intimate peri-implant mucosa response depending on timing of implant loading, immediate or delayed. Fifty-one screw implants Alpha Bio (Alpha-Bio Tec, Israel) were inserted in 42 partially edentulous patients according to standardized surgical techniques. At six months of loading, samples of peri-implant mucosa were harvested from 27 immediate loaded, respectively 24 delayed loaded implants, and subjected to microscopic examination...

AIM: To investigate the toxicity of the E-prostanoid 2 (EP2) receptor agonist, butaprost against human subconjunctival (Tenon's capsule) fibroblasts, and to determine the underlying mechanism. METHODS: We isolated Tenon's fibroblasts from the subconjunctival area of healthy subjects and evaluated the types of EP receptors expressed using quantitative real-time reverse transcription polymerase chain reaction (RT-PCR). The toxicity of butaprost against the fibroblasts was evaluated using methyl thiazolyl tetrazolium and lactic dehydrogenase assays...

INTRODUCTION: Although collagen-rich deposits are the main component of neural scars, the patterns of their formation are ill defined. Essential to the biosynthesis of collagen fibrils are enzymes catalyzing posttranslational modifications and chaperones that control the formation of the collagen triple helix. Prolyl-4-hydroxylase (P4H) and heat shock protein-47 (HSP47) play a key role, and their production is upregulated during scar formation in human tissues. Alpha smooth muscle actin (αSMA) is also produced during fibrotic processes in myofibroblasts that participate in fibrotic response...

BACKGROUND: The suturing technique and its associated complications could affect cosmetic outcome after facial surgery. Literature on this topic is limited. OBJECTIVE: To compare the cosmetic results 12 months after treatment and complications associated with simple interrupted sutures (SIS) versus running subcuticular sutures (RSS) in facial surgery. METHODS: A randomized, controlled multicenter trial was performed. Adults receiving dermatologic surgery on the face were randomized to receive SIS or RSS for wound closure...

REVIEW
Max Liebregts, Pieter A Vriesendorp, Jurrien M Ten Berg
Twenty years after the introduction of alcohol septal ablation (ASA) for the treatment of obstructive hypertrophic cardiomyopathy, the arrhythmogenicity of the ablation scar appears to be overemphasized. When systematically reviewing all studies comparing ASA with myectomy with long-term follow-up, (aborted) sudden cardiac death and mortality rates were found to be similarly low. The focus should instead shift toward lowering the rate of reinterventions and pacemaker implantations following ASA because, in this area, ASA still seems inferior to myectomy...

We present the case of a patient with severe postoperative scarring from surgical treatment for gastroschisis, with the intestine located immediately under the dermal scar. Although many patients are unsatisfied with the results of scar repair treatment, few reports exist regarding severe or difficult cases involving the surgical repair of postoperative scar contracture. We achieved an excellent result via simulation involving graph paper drawings that were generated using computed tomography images as a reference, followed by dermal scar deepithelialization...

BACKGROUND: There is contradictory evidence regarding negative memory biases in major depressive disorder (MDD) and whether these persist into remission, which would suggest their role as vulnerability traits rather than correlates of mood state. Early life stress (ELS), common in patients with psychiatric disorders, has independently been associated with memory biases, and confounds MDD versus control group comparisons. Furthermore, in most studies negative biases could have resulted from executive impairments rather than memory difficulties per se...

BACKGROUND: Frontal fibrosing alopecia (FFA) is an inflammatory condition of the scalp, which leads to scarring and slowly progressive recession of frontotemporal and/or frontoparietal hairline. Choice of FFA treatment is highly dependent on accurate assessment of disease phase, as medical treatments are effective only during the initial inflammatory stage. METHODS: To objectively quantify the activity of the inflammatory process in FFA, 22 female patients were examined by both infrared thermography and optical dermoscopy before tissue sampling...

Scar research is challenging because rodents do not naturally form excessive scars, and burn depth, size, and location cannot be controlled in human longitudinal studies. The female, red Duroc pig model has been shown to form robust scars with biological and anatomical similarities to human hypertrophic scars. To more closely mimic the mode of injury, recreate the complex chemical milieu of the burn wound environment and enhance scar development, an animal model of excessive burn-induced scarring was developed and compared with the more commonly used model, which involves excisional wounds created via dermatome...
