Autoimmune pancreatitis (AIP) is a distinct form of chronic pancreatitis that has been increasingly recognised over the last decades and shows a good response to corticosteroid treatment. Two different forms of AIP have been characterized. Type 1 AIP is the pancreatic manifestation of IgG4-related disease and often affects multiple organ systems. In contrast, type 2 AIP is confined to the pancreas and involvement of extra-pancreatic organs has previously only very rarely been reported, except for an association with inflammatory bowel disease. The hallmark lesion of type 2 AIP is the granulocyte epithelial lesion (GEL), showing infiltration of neutrophilic granulocytes in the epithelium of pancreatic ducts and their accumulation in the duct lumen. We present a 61-year-old female patient who underwent pancreaticoduodenectomy with a postoperative histological diagnosis of type 2 AIP. Three months later, she underwent colectomy and was diagnosed with ulcerative colitis. One year later, she presented with swelling and pain of the right-sided submandibular salivary gland which was resected. Sialadenitis with lymphoplasmacytic inflammation, obliterative phlebitis, fibrosis and frequent accumulation of neutrophilic granulocytes in ducts, reminiscent of GELs, without IgG4-positivity or epitheloid cell granulomas, was found. Later, she presented with swelling and pain related to the left-sided submandibular gland, which resolved after steroid treatment. We describe the clinical, histological and immunohistochemical findings in this patient. It may be hypothesized that the sialadenitis may represent a rare extrapancreatic manifestation of, alternatively a rare association with, type 2 AIP or ulcerative colitis.

Individuals receiving botulinum toxin A (BoNT-A) injections in the head and neck for migraine treatment have reported decreases in photophobia and sensations of dryness, independent of ocular surface parameters. We hypothesized that patients without migraine but with similar ocular neuropathic-like symptoms would also experience symptomatic improvement with periocular BoNT-A injections, independent of ocular surface changes.

Osteoma is the most frequent benign tumor in the craniomaxillofacial region. The most common initial manifestation is facial pressure or headache.The clinical examination showed increased volume in the right supraorbital region, asymmetry of the orbital contour, exophthalmia, dystopia, proptosis and clinical restraint of ocular movement for supraversion. The lesion measured approximately 4 cm in diameter with irregular contour. Osteotomy was performed with saw surrounding the tumor, with aid of a surgical piezo on the orbital medial wall.The result of histopathological examination was osteoma. The patient is 2.5 years postoperatively and so far without complications.

Currently, no clear diagnostic indicator of vertebral artery hypoplasia (VAH) or intracranial stenosis exists in clinic. This study aims to study the feasibility of neck-brain integrated ultrasound for evaluating stenosis of the intracranial segment in the vertebral artery by comparing with those of computed tomography angiography (CTA) and digital subtraction angiography (DSA).

The term 'medically unexplained symptoms' is used to cover a wide range of persistent bodily complaints for which adequate examination and appropriate investigations do not reveal sufficiently explanatory structural or other specified pathologies. A wide range of interventions may be delivered to patients presenting with medically unexplained symptoms in primary care. Many of these therapies aim to change the behaviours of the individual who may have worsening symptoms.

Soluble epoxide hydrolase (sEH), a novel therapeutic target for neuropathic pain, is a largely cytosolic enzyme that degrades epoxy-fatty acids (EpFAs), an important class of lipid signaling molecules. Many inhibitors of sEH have been reported, and to date, the 1,3-disubstituted urea has the highest affinity reported for the sEH among the central pharmacophores evaluated. An earlier somewhat water soluble sEH inhibitor taken to the clinic for blood pressure control had mediocre potency (both affinity and kinetics) and a short in vivo half-life. We undertook a study to overcome these difficulties, but the sEH inhibitors carrying a 1,3-disubstituted urea often suffer poor physical properties that hinder their formulation. In this report, we described new strategies to improve the physical properties of sEH inhibitors with a 1,3-disubstituted urea while maintaining their potency and drug-target residence time (a complementary in vitro parameter) against sEH. To our surprise, we identified two structural modifications that substantially improve the potency and physical properties of sEH inhibitors carrying a 1,3-disubstituted urea pharmacophore. Such improvements will greatly facilitate the movement of sEH inhibitors to the clinic.

A 75-year-old man with a history of atrial fibrillation (AF) and anticoagulant therapy presented with a headache. Cerebral amyloid angiopathy (CAA) was diagnosed after MRI of the brain revealed cortical superficial siderosis, lobar intracerebral hemorrhage, and lobar microbleeds. Anticoagulant therapy was carefully discontinued. Several years later, he was admitted with sudden onset left upper-extremity weakness. In addition to CAA bleeding lesions, a diffusion-weighted brain MRI showed multiple infarct lesions of high signal intensity. The administration of edoxaban 7.5 mg/day (later increased up to 30 mg/day) prevented ischemic stroke recurrence without exacerbation of cerebral bleeding. This could indicate that CAA patients with AF who had previous adverse effects from warfarin can safely use newer direct oral anticoagulants, such as edoxaban, to prevent ischemic stroke without danger of cerebral hemorrhage. The superiority of edoxaban as compared with warfarin might be due to its antioxidant effect because vascular oxidative stress plays a causal role in CAA-induced cerebrovascular dysfunction, CAA-induced cerebral hemorrhage, and CAA formation itself. We explained the beneficial effect of edoxaban for CAA by the mechanism of oxidative stress in the paper.

Introduction Avascular necrosis occurs due to impaired blood supply to the bone. It can be caused by fractures, dislocations, chronic steroid use, chronic alcohol use, coagulopathy, congenital source, and many other factors. It mostly affects the femoral head (hip joint). Its management can be conservative or invasive. Total hip arthroplasty is the treatment of choice for third and fourth stage avascular necrosis that can be cemented or uncemented. The purpose of this study is to access the functional outcomes of cementless total hip arthroplasty in patients with avascular necrosis of the hip. Materials and methods This prospective study was conducted at a major metropolitan hospital in Karachi, Pakistan over a period of six months. A total of 30 patients of age <60 years, either gender, and a confirmed diagnosis of avascular necrosis of hip with no other associated hip pathologies were included in this study. Demographic features, comorbidities, level of activity, range of movement before the development of avascular necrosis, Charnley's class, and laterality were noted. Cementless press-fit extensively porous-coated acetabular cup with or without cancellous screws and cementless press-fit extensively hydroxyapatite coated femoral stem were used through modified Gibson's posterior approach. The patients were checked for early and late complications, the position of acetabular and femoral components by radiography, and overall performance by Harris Hip Score (HHS) and modified HHS over a period of 12 months. All statistical analyses were performed using Statistical Package for Social Sciences (SPSS) version 19.0 (IBM Corp, Armonk, NY). Results The mean age was 43.9±6.7 years with 21 (70%) patients ranging from 40 to 60 years of age. There were 22 (73%) male and 8 (27%) female patients. Nine (30%) patients had diabetes mellitus, eight (27%) had hypertension, two (7%) had other comorbidities, and eleven (37%) had no comorbidities. A total of 11 (37%) patients were highly active, 18 (60%) were moderately active, and 1 (3%) was non-active before developing avascular necrosis. There were 4 (13%) patients in Charnley's class I, 15 (50%) in Charnley's class II, and 11 (37%) in Charnley's class III. Fifteen (50%) patients were operated on the left side, seven (23%) on the right side, and eight (27%) bilaterally. No significant early or late complications were noted. Acetabular component was found to be anteverted in 22 (73%), retroverted in zero (0%), neutral in 8 (27%), <35 inclined in 0 (0%), 35-50 inclined in 23 (77%), and >50 inclined in 7 (23%) patients, while femoral component was found neutral in 28 (93%), valgus in 2 (7%), and varus in zero (0%) patients on radiography at follow-up. On functional assessment, the HHS was 100% in 27 (90%) patients, 96% in 2 (7%) patients, and 83% in 1 (3%) patient with an average of 99.2%, while 29 (97%) patients had excellent and only 1 (3%) patient had a good outcome on modified HHS. Conclusions Cementless total hip arthroplasty, performed in patients <60 years of age and avascular necrosis of the hip with no other associated hip pathologies, has excellent functional outcomes with no pain, limping, physical deformity, difficulty in walking, difficulty in climbing stairs, difficulty using public transport, difficulty in sitting, or difficulty in wearing shoes and socks. They usually attain normal limb length and range of movement.

The benign glomus tumor is an uncommon cause of crippling pain most commonly associated with the fingers. This sheep in wolf's clothing is identified by careful examination, confirmed by MRI, and often resolved with a simple procedure. Here we present a patient with chronic knee pain of 21 years duration.

Primary dysmenorrhea (PD) is a chronic health condition that affects primarily young women and interferes with daily activities, causes loss of work productivity, and reduces quality of life. Transcutaneous electrical nerve stimulation (TENS) is a complementary and alternative therapy used to reduce pain related to PD. The purpose of this meta-analysis study was to evaluate the effectiveness of TENS in the treatment of pain in women with PD.
