Manuel John, M Raman, Keith Ryan
Ticks are tiny crawling bugs in the spider family that feed by sucking blood from animals. They are second only to mosquitoes as vectors of human disease, both infectious and toxic. Infected ticks spread over a hundred diseases, some of which are fatal if undetected. They spread the spirochete (which multiplies in the insect's gut) with a subsequent bite to the next host. We describe the only reported cases of peri ocular tick bite from India that presented to us within a span of 3 days and its management. Due suspicion and magnification of the lesions revealed the ticks which otherwise masqueraded as small skin tags/moles on gross examination...

BACKGROUND: Parotidectomy has well-documented post-operative complications. Dissection of the facial nerve branches can be challenging even under loupe magnification, and partial, or complete injury of the nerve branches can occur during surgery. To reduce this risk and the associated complications, we propose a number of microsurgical best practices, which can be performed during parotidectomy. METHODS: A retrospective survey was conducted on 109 patients (45 males and 64 females, average age 46...

BACKGROUND: Optimal vision and ergonomics are important factors contributing to achievement of good results during neurosurgical interventions. The operating microscope and the endoscope have partially filled the gap between the need for good surgical vision and maintenance of a comfortable posture during surgery. Recently, a new technology called video-assisted telescope operating monitor or exoscope has been used in cranial surgery. The main drawback with previous prototypes was lack of stereopsis...

BACKGROUND/AIM: In the colorectum, lymphoid follicles hyperplasia (LH) is sometimes observed as small, round, yellowish-white nodules. The novel image-enhanced endoscopy system named blue laser imaging (BLI) provides enhanced the contrast of surface vessels using lasers for light illumination. We investigated the endoscopic features of LH observed by using BLI endoscopy and its association with chronic bowel symptoms. PATIENTS/METHODS: 300 participants undergoing colonoscopy for various indications were enrolled...

Fibromyalgia (FM) syndrome is characterized by chronic widespread pain, muscle tenderness and emotional distress. Previous studies found reduced endogenous pain modulation in FM. This deficiency of pain modulation may be related to the attributes of chronic pain and other clinical symptoms experienced in patients with FM. Thus, we tested whether there is a link between the clinical symptoms of FM and functional connectivity (FC) of the periaqueductal gray (PAG), a key node of pain modulation. We acquired resting state 3T functional MRI (rsfMRI) data from 23 female patients with FM and 16 age- and sex- matched healthy controls (HC) and assessed FM symptoms with the Brief Pain Inventory (BPI), Fibromyalgia Impact Questionnaire (FIQ), Hospital Anxiety and Depression Scale (HADS) and Pain Catastrophizing Scale (PCS)...

BACKGROUND: Corynebacterium striatum is a member of the non-diphtherial corynebacteria, which are ubiquitous in nature and generally colonize the skin and mucous membranes of humans. Rarely, it causes infective endocarditis (IE). We report a case of rare left atrial bacterial vegetative mass due to C. striatum masquerading as a myxoma identified through a tortuous diagnostic process, and present a brief review of the relevant literature. CASE PRESENTATION: We present a case of 63-year-old man who presented with progressively worsening dyspnea on exertion and lower leg edema, and was diagnosed with heart failure...

BACKGROUND: Based on anecdotal and observational evidence, we hypothesized that the prevalence of cervical musculoskeletal disorder (C-MSD) would be high among plastic surgeons. A questionnaire review was undertaken to test this hypothesis. Ergonomic assessment was undertaken to assess causal factors of C-MSD. METHOD: An anonymous questionnaire recording demographics, physical symptoms and behavioral responses to C-MSD was distributed to UK Plastic Surgery consultants...

PURPOSE: The literature suggests that radiographs may be unnecessary in the initial evaluation of lateral epicondylitis because treatment is rarely altered as a result of the radiographic findings. The most commonly reported radiographic finding is calcification at the lateral epicondyle. Our goal was to perform a quantitative and qualitative analysis of this finding to determine its importance and possible relationship with various clinical factors and patient-reported measures. METHODS: All patients diagnosed with lateral epicondylitis by a single surgeon during a 5-year period were retrospectively reviewed...

BACKGROUND: Imaging and histology of clear-cell ependymoma and cerebellum-based hemangioblastoma are similar; distinguishing between them is a diagnostic challenge. CASE PRESENTATION: A 62-year-old Chinese woman presented with an intermittent headache of 8 years' duration. Computed tomography and magnetic resonance imaging revealed a mass in the cerebellum. Neurological imaging suggested hemangioblastoma (HB). Histologically, the tumor included cellular and paucicellular areas, in which cells were arranged in nests or diffusely distributed; and a highly vascular area, in which tumor cells were arranged in clusters and separated by capillaries...

OBJECTIVES: Endoscopic approach provides excellent magnification and visualization, and a purely transnasal approach is minimally invasive method. However, it is very difficult to repair anterior and lateral fractures with the previous transnasal endoscopic approaches, since repair of orbital fractures is managed through the middle meatus and ostium from the posterior side of the nasolacrimal duct with side-viewing endoscope and curved instruments. Therefore, the authors used modified transnasal endoscopic approach as an alternative for repair of orbital floor fractures in order to effectively reach the lateral or anterior fracture of the orbital floor with straight endoscope and instruments endoscopically...

BACKGROUND: Symptomatic lumbar spinal stenosis (LSS) is the most common reason for lumbar surgery in the elderly. There is growing evidence that decompressive surgery offers an advantage over non-surgical management for selected patients with persistent severe symptoms. Based on treatment traditions, open laminectomy has been the gold standard surgical treatment, but various other surgical and non-surgical treatments for LSS are widely used in clinical practice. Therefore, we conducted a survey study to capture potential diversities in surgeons' management of LSS in Norway...

Background. Identifying which patients are most likely to be at risk of chronic pain and other postconcussion symptoms following mild traumatic brain injury (MTBI) is a difficult clinical challenge. Objectives. To examine the relationship between pain catastrophizing, defined as the exaggerated negative appraisal of a pain experience, and early MTBI outcome. Methods. This cross-sectional design included 58 patients diagnosed with a MTBI. In addition to medical chart review, postconcussion symptoms were assessed by self-report at 1 month (Time 1) and 8 weeks (Time 2) after MTBI...

OBJECTIVE: Although reducing pain catastrophizing has been shown to contribute to functional improvement in patients receiving interdisciplinary pain care, little is known about how changes in the different dimensions of pain catastrophizing uniquely contribute to improvement in outcome. The study examined the unique relationship between changes in the 3 distinct factors of pain catastrophizing-helplessness, rumination, and magnification-and changes in pain outcomes. MATERIALS AND METHODS: In this nonrandomized study, 641 patients who completed treatment in a 3-week interdisciplinary pain rehabilitation program between the years 2013 and 2014 completed a battery of psychometrically validated measures of pain catastrophizing, pain severity, pain interference, mental and physical health-related quality of life, and depressive symptoms at pretreatment and posttreatment...

OBJECTIVES: To identify whether mast cell densities in vulvar biopsies from the vestibule are associated with vulvodynia. METHODS: We enrolled 100 women aged 19 to 59 years with confirmed vulvodynia cases, 100 racially matched controls, and 100 black control women. All had vulvar biopsies performed at the 7 o'clock position of the vestibule, which were then immunostained to detect c-KIT protein. The numbers of c-KIT positive mast cells per ×400 magnification field were manually counted, and t tests and logistic regression were used to assess the association with case-control status...
