    Transgender individuals experience unique challenges with regards to discrimination and access to health care. Further, their unique health-care needs and challenges lead to greater rates of morbidity. This article seeks to review the unique biology of transgender patients and the effects of cross-sex hormone therapy on ophthalmic and non-ophthalmic pathology. Attention is given to topics in neuro-ophthalmology, oculoplastics, and retinal disease. PMID:27128494

    Transient ischemic attack (TIA) is a transient neurological deficit of cerebrovascular origin without infarction which may last only for a short period and can have varying presentations. We report a case of 58-year-old male with presenting features of sudden onset transient vertical diplopia and transient rotatory nystagmus which self-resolved within 12 h. Patient had no history of any systemic illness. On investigating, hematological investigations and neuroimaging could not explain these sudden and transient findings. A TIA could possibly explain these sudden and transient ocular findings in our patient. This case report aims to highlight the importance of TIA for ophthalmologists. We must not ignore these findings as these could be warning signs of an impending stroke which may or may not be detected on neuroimaging. Thus, early recognition, primary prevention strategies, and timely intervention are needed.

  3. Refsum disease: the presentation and ophthalmic aspects of Refsum disease in a series of 23 patients.

    PubMed

    Refsum disease (heredopathia atactica polyneuritiformis) was first described in 1946 and is a rare recessively inherited metabolic disease affecting phytanic acid metabolism. It causes retinitis pigmentosa, cataracts, a chronic polyneuropathy, cerebellar ataxia and cardiac arrhythmias amongst other clinical signs. By limiting dietary intake, plasma phytanic acid levels fall with an improvement in the neurological signs. The onset of retinitis pigmentosa usually precedes biochemical diagnosis by several years by which time the retinal damage is severe. A series of 23 patients have been reviewed. There was an average delay of 11 years (range 1-28 years) between the patient presenting to the ophthalmologist and being diagnosed as having Refsum disease. Although serial examinations have failed to show a definite change in the course of visual deterioration with treatment, early diagnosis is important to prevent the development of neurological disease.

  4. Health literacy and ophthalmic patient education.

    PubMed

    Muir, Kelly W; Lee, Paul P

    2010-01-01

    In 1997, Ebrahimzadeh, Davalos, and Lee wrote in this journal that only 32% of the ophthalmic patient educational materials reviewed were written at or below the recommended eighth-grade reading level. Since that time, the National Assessment of Adult Literacy found that more than one-third of adult Americans possess only basic or below basic health literacy skills, defined as the ability to understand written information in a healthcare setting. Subsequently, investigators have shown that poor health literacy skills are associated with poor prescription medication adherence, increased hospital admissions, and increased mortality. We review the readability of currently available ophthalmic educational materials, with particular attention to the health literacy status of the patient population for which the materials are intended. Examples of prose at various readability levels are provided. Optimizing patient education and improving clinical outcomes requires understanding the attributes that the patient brings to the patient-physician relationship, including health literacy.

  5. DRESS syndrome in ophthalmic patients.

    PubMed

    Sousa, Jacqueline Martins de; Nascimento, Heloisa; Belfort, Rubens

    2016-01-01

    Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal adverse drug reaction associated with skin rash, fever, eosinophilia, and multiple organ injury. A number of pharmacological agents are known to cause DRESS syndrome such as allopurinol, anticonvulsants, vancomycin, trimethoprime-sulfamethoxazole, and pyrimethamine-sulfadiazine. Here, we describe two patients who developed DRESS syndrome during ocular treatment. The first case was being treated for late postoperative endophthalmitis with topical antibiotics, intravenous cephalothin, meropenem, and intravitreal injection of vancomycin and ceftazidime before symptoms developed. We were unable to identify the causal drug owing to the large number of medications concurrently administered. The second case presented with DRESS syndrome symptoms during ocular toxoplasmosis treatment. In this case, a clearer association with pyrimethamine-sulfadiazine was observed. As a result of the regular prescription of pharmacological agents associated with DRESS syndrome, ophthalmologists should be aware of the potentially serious complications of DRESS syndrome.

    2014-01-01

    Background The learning preferences of ophthalmology patients were examined. Methods Results from a voluntary survey of ophthalmology patients were analyzed for education preferences and for correlation with race, age, and ophthalmic topic. Results To learn about eye disease, patients preferred one-on-one sessions with providers as well as printed materials and websites recommended by providers. Patients currently learning from the provider were older (average age 59 years), and patients learning from the Internet (average age 49 years) and family and friends (average age 51 years) were younger. Patients interested in cataracts, glaucoma, macular degeneration, and dry eye were older; patients interested in double vision and glasses were younger. There were racial differences regarding topic preferences, with Black patients most interested in glaucoma (46%), diabetic retinopathy (31%), and cataracts (28%) and White patients most interested in cataracts (22%), glaucoma (22%), and macular degeneration (19%). Conclusion Most ophthalmology patients preferred personalized education: one-on-one with their provider or a health educator and materials (printed and electronic) recommended by their provider. Age-related topics were more popular with older patients, and diseases with racial risk factors were more popular with high risk racial groups. PMID:24812493

    2013-01-01

    A 24-year-old Ugandan woman was referred for a neurology opinion after complaining of a year long history of right-sided retro-orbital stabbing pain. Brain imaging revealed a coincidental 3 mm left ophthalmic artery aneurysm. Marfanoid habitus was noted; after further investigations she was diagnosed with mild aortic root dilatation, subtle lens dislocation and Marfan syndrome. Her symptoms were secondary to temporomandibular joint dysfunction, an under-recognised complication of Marfan syndrome. Her ophthalmic artery aneurysm is likely to be a coincidental finding.

    2016-01-01

    Objective Rebamipide ophthalmic suspension was developed for the treatment of dry eyes and for other corneal diseases, promoting the secretion of both mucin in tear fluid and membrane-associated mucin, increasing the number of goblet cells, and restoring the barrier function of the corneal epithelium. We report a case of a persistent corneal epithelial defect in a patient with diabetes treated with topical application of rebamipide ophthalmic suspension. Case presentation A 73-year-old woman had a history of type 2 diabetes for 35 years and nonproliferative diabetic retinopathy for 23 years. She presented to our department with discharge and ophthalmalgia in the left eye. A corneal ulcer was detected, and culture of corneal scrapings was performed, with Staphylococcus aureus and Streptococcus canis being isolated. The infection was treated with levofloxacin eye drops and ofloxacin ophthalmic ointment based on the sensitivity profile of the isolate. However, a corneal epithelial defect persisted for approximately 2 months despite continuing treatment with 0.1% hyaluronic acid ophthalmic suspension and 0.3% ofloxacin eye ointment. Her hemoglobin A1c was 7.3%. The persistent corneal epithelial defect showed improvement at 2 weeks after treatment with rebamipide unit dose 2% ophthalmic suspension, and it did not recur even when vitrectomy was subsequently performed for vitreous hemorrhage due to progression of diabetic retinopathy. Conclusion This is the first report about efficacy of rebamipide unit dose 2% ophthalmic suspension for presenting persistent corneal epithelial defect in a patient with diabetes. In the present case, the suggested mechanisms are the following: improving the corneal barrier function, stabilization of mucin on the keratoconjunctival epithelium, and improving the wettability and stability of the tear film, which resulted in the promotion of healing of the corneal epithelial defect in a short time period.

    Context Music and surgery. Objective To determine the effect of live classical piano music on vital signs of patients undergoing ophthalmic surgery. Design Retrospective case series. Setting and Patients 203 patients who underwent various ophthalmologic procedures in a period during which a piano was present in the operating room of St. Francis Medical Center. [Note: St. Francis Medical Center has recently been renamed Hawaii Medical Center East.] Intervention Demographic data, surgical procedures, and the vital signs of 203 patients who underwent ophthalmic procedures were obtained from patient records. Blood pressure, heart rate, and respiratory rate measured in the preoperative holding area were compared with the same parameters taken in the operating room, with and without exposure to live piano music. A paired t-test was used for statistical analysis. Main outcome measure Mean arterial pressure, heart rate, and respiratory rate. Results 115 patients who were exposed to live piano music showed a statistically significant decrease in mean arterial blood pressure, heart rate, and respiratory rate in the operating room compared with their vital signs measured in the preoperative holding area (P < .0001). The control group of 88 patients not exposed to live piano music showed a statistically significant increase in mean arterial blood pressure (P < .0002) and heart rate and respiratory rate (P < .0001). Conclusion Live classical piano music lowered the blood pressure, heart rate, and respiratory rate in patients undergoing ophthalmic surgery. PMID:18679538

    Symptomatic obstructive sleep apnea (OSA) affects 2% of women and 4% of men, but the prevalence of asymptomatic OSA is significantly higher. Several ophthalmic conditions are associated with OSA, including floppy eyelid syndrome, glaucoma, nonarteritic anterior ischemic optic neuropathy, papilledema, keratoconus, and central serous chorioretinopathy. The purpose of this review is to provide primary care physicians with a general knowledge of the signs, symptoms, and management of the ophthalmic diseases associated with OSA. PMID:27455101

    2012-01-01

    Background The purpose of this study was to determine the efficacy of besifloxacin ophthalmic suspension 0.6% when used in the treatment of bacterial conjunctivitis infections due to Pseudomonas aeruginosa. Methods We undertook a post hoc analysis of clinical outcomes in patients with bacterial conjunctivitis due to P. aeruginosa across four prospective, multicenter, double-masked, randomized, controlled, clinical studies of besifloxacin ophthalmic suspension 0.6%. Efficacy outcomes included bacterial eradication and clinical resolution of the baseline infection at follow-up visits. Bacterial eradication was defined as the absence of ocular bacterial species present at or above threshold at baseline, while clinical resolution was defined as grade 0 ocular discharge and bulbar conjunctival injection. Safety outcomes included the incidence of adverse events, changes in visual acuity, and biomicroscopy and ophthalmoscopy findings. Patient outcomes were summarized and bacterial eradication and clinical resolution rates integrated. Results Of 1317 patients with culture-confirmed bacterial conjunctivitis across four clinical studies, nine (0.7%) were infected with P. aeruginosa at baseline, and of these, five were randomized to treatment with besifloxacin ophthalmic suspension 0.6%. Bacterial eradication of the baseline infection was observed at both follow-up visits in all five patients. Clinical resolution was achieved in two of five patients by the first follow-up visit and four of five patients by the second follow-up visit. There were no adverse events reported in these patients. There were no clinically meaningful biomicroscopy findings or changes in ophthalmoscopy or visual acuity. Conclusion The incidence of bacterial conjunctivitis due to P. aeruginosa was low. Treatment of patients with P. aeruginosa infections with besifloxacin ophthalmic suspension 0.6% led to bacterial eradication of P. aeruginosa by the first follow-up visit and high rates of clinical

    Clinch, Thomas E.

    2014-01-01

    Purpose: The aim of the study was to evaluate the safety of besifloxacin ophthalmic suspension 0.6% as antibacterial prophylaxis in the surgical setting. Methods: Two prospective safety surveillance studies were conducted—one in the cataract surgery setting and the other in the laser-assisted in situ keratomileusis (LASIK) surgery setting. Cases from patients aged 18 years and above were eligible for inclusion. In both surveillance studies, data were collected from consecutive cases of routine primary cataract surgery and LASIK surgery, respectively, in which besifloxacin ophthalmic suspension 0.6% or moxifloxacin ophthalmic solution 0.5% was used as the topical perioperative prophylactic antibacterial medication as part of the clinician's routine standard of care. The primary safety endpoint was the incidence of treatment-emergent adverse events (TEAEs). Results: The cataract surgery surveillance study included 485 cases/eyes (besifloxacin, n = 333; moxifloxacin, n = 152), whereas the LASIK surveillance study included 456 cases/eyes (besifloxacin, n = 344; moxifloxacin, n = 112). In the cataract study, only 1 TEAE was reported in a besifloxacin case (mild hypersensitivity/allergic reaction considered possibly related to besifloxacin). No TEAEs were reported in the LASIK study. In both studies, surgical outcomes were similar with both treatments. The frequency of preoperative and/or postoperative dosing was generally lower for besifloxacin than that for moxifloxacin. Conclusions: In prospective safety surveillance studies of patients undergoing cataract extraction or LASIK, TEAEs associated with prophylactic use of besifloxacin ophthalmic suspension 0.6% were rare, and surgical outcomes with besifloxacin were similar to those with moxifloxacin ophthalmic solution 0.5%.

    Ophthalmic artery occlusion usually presents as a sudden onset profound decrease in vision in the middle-aged and elderly patients following periocular procedures (retrobulbar injection/glabellar fat injection), embolism from the heart or after prolonged systemic surgery. In this report, we describe three children with spontaneous ophthalmic artery occlusion who presented with unilateral loss of vision and diagnosed elsewhere as optic atrophy whose detailed history and examination were suggestive of ophthalmic artery occlusion. Detailed systemic and laboratory evaluation revealed hyperhomocysteinemia as the only potential risk factor. To the best of our knowledge, this is the first report of the association of hyperhomocysteinemia and spontaneous ophthalmic artery occlusion. PMID:26622143

    2014-01-01

    Clinical outcomes, such as quantifying the extent of visual field loss by automated perimetry, are valued highly by health professionals, but such measures do not capture the impact of the condition on a patient's life. Patient-reported outcomes describe any report or measure of health reported by the patient, without external interpretation by a clinician or researcher. In this review, we discuss the value of the measures that capture this information (patient-reported outcome measures; PROMs), and why they are important to both the clinician and the researcher. We also consider issues around developing or selecting a PROM for ophthalmic research, the emerging challenges around conducting and reporting PROMs in clinical trials and highlight best practice for their use. Search terms for this review comprised: (1) (patient-reported outcomes OR patient-reported outcome measures) AND (2) randomised controlled trials AND (3) limited to ophthalmic conditions. These terms were expanded as follows: (((‘patients'(MeSH Terms) OR ‘patients'(All Fields) OR ‘patient'(All Fields)) AND (‘research report'(MeSH Terms) OR (‘research'(All Fields) AND ‘report'(All Fields)) OR ‘research report'(All Fields) OR ‘reported'(All Fields)) AND outcomes(All Fields)) OR ((‘patients'(MeSH Terms) OR ‘patients'(All Fields) OR ‘patient'(All Fields)) AND (‘research report'(MeSH Terms) OR (‘research'(All Fields) AND ‘report'(All Fields)) OR ‘research report'(All Fields) OR ‘reported'(All Fields) AND (‘outcome assessment (health care)'(MeSH Terms) OR (‘outcome'(All Fields) AND ‘assessment'(All Fields) AND ‘(health'(All Fields) AND ‘care)'(All Fields)) OR ‘outcome assessment (health care)'(All Fields) OR (‘outcome'(All Fields) AND ‘measures'(All Fields)) OR ‘outcome measures'(All Fields)))) AND (‘randomized controlled trial'(Publication Type) OR ‘randomized controlled trials as topic'(MeSH Terms) OR ‘randomised controlled trials'(All Fields) OR

    Purpose The purpose of this study is to evaluate the success and usefulness of patient education in eyedrop self-administration technique via an educational handout and a short instructional video. Patients and methods We conducted a prospective study that included 34 patients who were self-administering ophthalmic drops. Of the total patients included, 12% had used drops for <12 months, and 88% had used drops for >12 months. Average age of patients in the study was 67 years, with an age range of 19–91 years. Of the total patients included, 82% had glaucoma, 6% had dry eyes, and 12% did not have a specific diagnosis. Subjects were video recorded and assessed by a trained observer on two occasions: at baseline and after they viewed a demonstrational video and handout. A maximum score of 15 points was awarded based on 15 criteria. A written self-assessment was administered at the end of each study. Results Pre- and post-teaching assessment scores improved significantly with education. Patients initially scored an average 2.53 points compared to a post-education score of 6.15 out of 15 points, demonstrating a 2.43 (P=0.008) factor of improvement. After education, 94% of patients versus 47% pre-teaching (P=0.0001) pulled down their lower eyelids. A total of 91% pre-teaching versus 59% post-teaching (P=0.0042) patients squeezed one drop into the lower fornix, 74% pre-teaching versus 26% post-teaching (P=0.0002) patients released the eyelid and closed the eye for 1 minute, and 56% pre-teaching versus 3% post-teaching (P=0.0001) patients applied nasal digital pressure on each eye. We found no significant difference in score changes between those who previously received education and those who had not (P=0.37). A total of 91% patients responded in a postassessment survey that they now feel more confident of their ability to self-administer eyedrops as their doctor prescribed and that the educational materials were responsible. Conclusion Participants demonstrated an

    Purpose: Educating patients about their diagnosis and proposed management is integral part of healthcare. Often patient noncompliance is due to a lack of knowledge that could result in irreversible ocular damage. In an era where access to information is virtually unlimited, an understanding of the preferred method of eye care education among patients is required for greater effectiveness in lowering morbidity and mortality of diseases. Subjects and Methods: Patients visiting the ophthalmology clinics of a tertiary hospital in Riyadh, Saudi Arabia, were interviewed. This cross-sectional study was conducted between December 2014 and March 2015. A representative sample of 200 patients was enrolled. Close-ended questionnaire covering current and client preferred health promotion methods were used to collect clients’ response. Data were analyzed with descriptive statistics. Results: Out of the 200 participants, 110 (55%) were males. The majority (n = 154; 77%) listed an ophthalmologist as their current primary source of information regarding their eye condition. Approximately half of the participants (n = 95; 48%) were keen to be educated regarding the causes of the eye disease. The top four educational methods preferred by patients were one-on-one session with an eye care provider (n = 116; 58%), a group session with an eye care provider (n = 30; 15%), an application on a smartphone (n = 53; 27%), video lectures on eye health and diseases (n = 8; 4%). Conclusion: Majority of patients in ophthalmic care prefer a one-on-one session with an eye care provider for their eye care education. PMID:27162447

    We present two patients with a dural arteriovenous fistula (dAVF) of the ophthalmic sheath who developed progressive exophthalmos, conjunctival chemosis, and visual loss. These symptoms mimic those of cavernous sinus dAVFs. Dural AVFs of the ophthalmic sheath are extremely rare and their clinical management is controversial. We successfully treated these two patients by transvenous coil embolization. Transvenous embolization appears to be a safe and effective method to treat dAVFs of the ophthalmic sheath.

  13. Gatifloxacin Ophthalmic Solution for Treatment of Bacterial Conjunctivitis: Safety, Efficacy and Patient Perspective

    PubMed Central

    Schultz, Clyde

    2012-01-01

    Gatifloxacin is a fourth generation fluroquinolone antibiotic that has been prescribed for systemic use. However, the drug which was developed by Kyorin (Japan) was linked to toxic reactions and death and was banned in the United States and Canada for use as an oral dosage form. It continues to be used as a topical application for ophthalmic conditions as the systemic toxicity seen when taking the drug orally has not been observed with ophthalmic use. The available data indicate that ocular use of gatifloxacin is safe, and effective against a broad spectrum of bacteria, including intracellular bacteria and anaerobes. PMID:23650458

    Background Patients undergoing ophthalmic surgery are usually elderly and, due to systemic disease, may be on long-term therapy, such as antithrombotic agents. Rates of hemorrhagic complications associated with invasive procedures may be increased by the use of anticoagulants and antiplatelet agents. Objective To compare the incidence of hemorrhagic complications in patients undergoing needle-based ophthalmic regional anesthesia between patients on antithrombotic therapy and those not on such therapy. Methods A systematic review was conducted by two independent reviewers based on searches of Cochrane, LILACS, PubMed, Scopus, Web of Science, and the “gray” literature (Google Scholar). The end search date was May 8, 2015, across all databases. Results Five studies met the eligibility criteria. In three studies, individual risk of bias was low, and in two of them, moderate. In all studies, no differences regarding mild to moderate incidence of hemorrhagic complications were found between patients using antithrombotics (aspirin, clopidogrel, and warfarin) and those not using them. Rates of severe hemorrhagic complication were very low (0.04%) in both groups, supporting the safety of needle blocks, even in patients using antithrombotics. High heterogeneity across studies prevented meta-analysis. Limitations to these results include low statistical power in three experimental studies and a large 95% confidence interval in the two retrospective cohorts. Conclusion In this review, none of the selected studies showed significant bleeding related to needle-based ophthalmic regional anesthesia in association with the use of aspirin, clopidogrel, or vitamin K inhibitors. Since the available data is not powerful enough to provide a reliable evaluation of the true effect of antithrombotics in this setting, new studies to address these limitations are necessary.

    Introduction Benzalkonium chloride (BAK), included as a preservative in many topical treatments for glaucoma, induces significant toxicity and alters tear breakup time (TBUT). BAK-containing latanoprost, an ester prodrug of prostaglandin F2α, can cause ocular adverse events (AEs) associated with BAK. The purpose of this study was to evaluate the efficacy and safety of BAK-free latanoprost. Patients and methods A prospective, open-label, single-arm, multicenter, 8-week study in patients with primary open-angle glaucoma or ocular hypertension taking BAK-containing latanoprost for ≥12 months was performed. Patients were switched to BAK-free latanoprost ophthalmic solution 0.005% administered once daily, and eyes were assessed after 28 and 56 days. Primary efficacy and safety variables were TBUT and treatment-emergent AEs, respectively. Results At day 56, 40 eyes were evaluable. Mean TBUT increased significantly from baseline (3.67±1.60 seconds) to 5.03±2.64 and 6.06±3.39 seconds after 28 and 56 days of treatment with BAK-free latanoprost (P<0.0001). Ocular Surface Disease Index© (OSDI©) score also decreased significantly to 12.06±13.40 and 7.06±10.75 at 28 and 56 days, respectively, versus baseline (18.09±18.61, P<0.0001). In addition, inferior corneal staining score decreased significantly to 0.53 from baseline (0.85, P=0.0033). A reduction in conjunctival hyperemia and intraocular pressure was observed at both time points. No treatment-related serious AEs were evident and 12 (26.08%) treatment-emergent AEs occurred in seven patients, with eye pain and irritation being the most frequent. No clinically significant changes in vital signs or slit lamp examinations were observed. Conclusion Results indicate that switching from BAK-containing latanoprost to BAK-free latanoprost resulted in significant improvements in TBUT, OSDI© score, and inferior corneal staining score, and measurable reductions in conjunctival hyperemia score. Furthermore, BAK

    Settings and Design: This study documents a survey of final-year ophthalmology postgraduates on the subject of their surgical training and their future plans after residency. Purpose: This survey aimed to answer the question, What is the present status of surgical training in ophthalmic training centers? by obtaining information from students about (1) various methods used in surgical training (2) numbers and types of surgeries performed by them in the training centers (3) their plans after residency. Materials and Methods: A questionnaire containing 21 questions was distributed to 155 students attending an intensive 4-day teaching program. The questions related to orientation training, wet lab training, facilities for training, free surgical camps and detailed information about numbers and types of surgeries observed and performed. Completed questionnaires were collected, and responses analyzed. Results: One hundred and seven completed responses were analyzed. The majority had not received formal orientation training. More than half had undergone wet lab training. Most residents performed their first ophthalmic surgery during the 1st year of residency and went to the operation theatre multiple times a week. Most of the students planned to undergo further training after residency. More than half of the students found their surgical training to be fair or satisfactory. Conclusions: The number and frequency of ophthalmic surgeries done by residents appear satisfactory, but further efforts from trainers on enhancing the quality and range of surgical training would benefit students and improve their satisfaction.

    We report 13 cases of ophthalmic complications resulting from dengue infection in Singapore. We performed a retrospective analysis of a series of 13 patients with dengue fever who had visual impairment. Investigations included Humphrey automated visual field analyzer, Amsler charting, fundus fluorescein angiography, and optical coherence tomography. Twenty-two eyes of 13 patients were affected. The mean age of patients was 31.7 years. Visual acuity varied from 20/25 to counting fingers only. Twelve patients (92.3%) noted central vision impairment. Onset of visual impairment coincided with the nadir of serum thrombocytopenia. Ophthalmologic findings include macular edema and blot hemorrhages (10), cotton wool spots (1), retinal vasculitis (4), exudative retinal detachment (2), and anterior uveitis (1). All patients recovered visual acuity to 20/30 or better with residual central scotoma by 12 weeks. These new complications suggest a widening spectrum of ophthalmic complications in dengue infection.

    Ophthalmic artery hypoperfusion is a relatively uncommon clinical entity. This study illustrates the posterior segment findings of ophthalmic artery hypoperfusion in a series of nine patients. Colour photographs and relevant fluorescein angiograms highlighting the findings are shown. The retinal manifestations of ophthalmic artery hypoperfusion in this series of patients include midperipheral haemorrhages, dilated retinal veins, optic disk collaterals, optic disk neo-vascularization, cotton wool spots, grey intraretinal lesions, fundus pallor, optic disk swelling and choroidal infarcts. Recognition of the ophthalmic changes in this condition may lead to detection of carotid artery disease, the surgical and medical treatment of which has important bearing on patient management.

    Timolol Maleate (also called Timolol) is a nonselective beta-adrenergic blocker and a class II antiarrhythmic drug, which is used to treat intraocular hypertension. It has been reported to cause systemic side effects especially in elderly patients with other comorbidities. These side effects are due to systemic absorption of the drug and it is known that Timolol is measurable in the serum following ophthalmic use. Chances of life threatening side effects increase if these are coprescribed with other cardiodepressant drugs like calcium channel or systemic beta blockers. We report a case where an elderly patient was admitted with three side effects of Timolol and his condition required ICU admission with mechanical ventilation and temporary transvenous pacing. The case emphasizes the need of raising awareness among physicians of such medications about the potential side effects and drug interactions. A close liaison among patient's physicians is suggested.

    Background: Seasonal allergic conjunctivitis (SAC) is the most common and most prevalent of allergic disorders which afflict the ocular surface. Of the several treatments available, ophthalmic non-steroidal anti-inflammatory drugs, are generally very safe and tolerable. Aim: The aim of this study is to compare the ocular efficacy and safety of diclofenac sodium (0.1%) ophthalmic solution with that of ketorolac tromethamine (0.5%) ophthalmic solution in patients with acute SAC. Materials and Methods: Sixty patients with signs and symptoms of SAC were evaluated in an open, randomized, parallel group study. The principle symptoms (ocular itching, burning, discharge, photophobia) and signs (ocular inflammation, lid edema, chemosis, conjunctival mucous, keratitis) were evaluated. Study Design: Patients were randomized into two groups of 30 each. Patients in group A received one drop of diclofenac sodium 0.1% and patients in group B received ketorolac tromethamine 0.5% in both the eyes four times a day for fourteen days. Evaluations were performed at day 0, 3, 7 and 14 of the therapy. At each visit, the signs and symptoms were rated using a scale from 0-3 (mild-1, moderate-2 and severe-3). Results: Significant clinical and statistical reductions in signs and symptoms from baseline were observed in both groups. Diclofenac sodium 0.1% was superior to ketorolac tromethamine 0.5% in reducing ocular itching (P < 0.05) and ocular inflammation (P < 0.05), at the final examination. Conclusion: Diclofenac sodium showed statistically significant better results at day 3 and 7 compared to ketorolac. PMID:23776804

    Purpose To investigate the long-term results of 3% diquafosol ophthalmic solution as an alternative therapy to existing ophthalmic solutions, including topical immunosuppression, for the treatment of dry eye in patients with Sjögren's syndrome. Methods This study involved 14 female dry-eye patients (mean age: 62.4 years) with Sjögren's syndrome who insufficiently responded to their current therapy. In all patients, 3% diquafosol ophthalmic solution was administered six times daily for 12 months in substitution for artificial tears and sodium hyaluronate ophthalmic solution. Their use of corticosteroid eye drops remained unchanged from that prior to the treatment with diquafosol sodium. The subjective symptoms assessed, and ocular signs including tear meniscus radius and the tear film breakup time, and ocular-surface epithelial damage score were examined at 1, 2, 3, 4, 5, 6, 9, and 12 months after initiating treatment. Results Among the subjective symptoms, significant improvement was obtained in dryness at 2 months post treatment, in eye fatigue at 1, 2, 3, 4, and 12 months post treatment, and in pain at 1, 2, 6, and 12 months post treatment. Difficulty in opening the eye, foreign body sensation, and redness were also significantly ameliorated at various time-points. The tear meniscus radius and the tear film breakup time were significantly improved throughout the observation period, and the corneal epithelial staining scores were significantly decreased at 3 months post treatment. Conclusions In dry-eye patients with Sjögren's syndrome, treatment with 3% diquafosol ophthalmic solution improved both symptoms and signs, and that effectiveness was maintained for 12 months.

    Purpose: The aims of this study were to determine the acceptability levels of different styles of the doctors’ dress and the expectations from the initial phases of physician-patient encounter. Methods: The study design was a cross-sectional descriptive type using the survey methodology. A survey based on a five-point questionnaire was performed on all consecutive patients or their caregivers, aged ≥15, visiting the ophthalmic plastics outpatient clinics at a tertiary eye care institute. The participants were shown three sets of photographs and were required to answer a questionnaire which consisted of five questions. Data collected include participant demographics and their preferences with regards to the physician's attire and initial communications. Results: A total of 300 consecutive responses were analyzed. The mean age of the participants was 37.2 years. Among the participants, 87.6% (263/300) and 90.3% (271/300) preferred a white coat for the male and female physicians, respectively (P < 0.001). The most common second preference was scrubs for both the males and female physicians. 92.3% (277/300) preferred the attire to have an identification display. The overwhelming majority of respondents (95.6%, 287/300) preferred the physicians to address them by their name and 98.6% (296/300) liked if their physicians smiled while addressing them. Conclusions: White coat was the main preferred attire among respondents. Increased awareness of the patient's expectations plays a crucial role in enhancing their satisfaction. PMID:27488153

    In the past decade ophthalmic anesthesia has witnessed a major transformation. The sun has set on the landscape of ophthalmic procedures performed under general anesthesia at in-hospital settings. In its place a new dawn has ushered in the panorama of eye surgeries conducted under regional and topical anesthesia at specialty eye care centers. The impact of the burgeoning geriatric population is that an increasing number of elderly patients will present for eye surgery. In order to accommodate increased patient volumes and simultaneously satisfy administrative initiatives directed at economic frugality, administrators will seek assistance from anesthesia providers in adopting measures that enhance operating room efficiency. The performance of eye blocks in a holding suite meets many of these objectives. Unfortunately, most practicing anesthesiologists resist performing ophthalmic regional blocks because they lack formal training. In future, anesthesiologists will need to block eyes and manage common medical conditions because economic pressures will eliminate routine preoperative testing. This review addresses a variety of topical issues in ophthalmic anesthesia with special emphasis on cannula and needle-based blocks and the new-generation antithrombotic agents. In a constantly evolving arena, the sub-Tenon’s block has gained popularity while the deep angulated intraconal (retrobulbar) block has been largely superseded by the shallower extraconal (peribulbar) approach. Improvements in surgical technique have also impacted anesthetic practice. For example, phacoemulsification techniques facilitate the conduct of cataract surgery under topical anesthesia, and suture-free vitrectomy ports may cause venous air embolism during air/fluid exchange. Hyaluronidase is a useful adjuvant because it promotes local anesthetic diffusion and hastens block onset time but it is allergenic.

    Toxoplasmosis is an infection of worldwide distribution caused by Toxoplasma gondii, and infects a large proportion of the world population. Only under certain circumstances of severe immunosuppression can the parasite reactivate and cause disease. The most common form of presentation of this pathology in patients with positive HIV is the brain abscess. One of the extra-cerebral forms is toxoplasmic chorioretinitis, which could lead to a chronic active form of a slowly progressive retinitis. Diagnosis is made by observing the eye fundus and confirmed by the scarring obtained after specific treatment. We report a case of a patient with diabetes and positive HIV, in whom a toxoplasmic scar injury was detected in the annual retinography follow-up. A conservative therapeutic approach was decided, with regular check-ups for possible detection of disease activation.

    Introduction Loteprednol etabonate (LE) ophthalmic gel 0.5% (Lotemax®) is a new polycarbophil-based, nonsettling topical ophthalmic formulation. The formulation is a semisolid gel at rest and a shear thinning fluid when expressed through a dropper tip. The present study was undertaken to determine how the nonsettling character of LE ophthalmic gel affects dose uniformity. Prednisolone acetate ophthalmic suspension 1% (Pred Forte®) and a generic prednisolone acetate suspension 1% were used as comparators. Methods Drug concentrations of LE ophthalmic gel, Pred Forte, and a generic prednisolone acetate suspension were determined following simulated dosing – consisting of 2 drops, expressed four times daily for 2 weeks, with bottles that were shaken or not shaken immediately prior to expressing the drops. Drug concentrations were determined using a reverse-phase high-performance liquid chromatography (HPLC) method and reported as a percentage of the declared (labeled) concentration. Comparative kinetics of drug particle sedimentation were also determined for each formulation, using dispersion analysis under gravity. Results Mean drug concentrations in drops of all three formulations were within a few percentage points of the declared concentration when the bottles were shaken for 5 seconds prior to dispensing. Only LE ophthalmic gel showed consistent and on-target concentrations when the bottles were unshaken prior to dispensing, with a mean (standard deviation [SD]) percent declared concentration of 102% (1.92%) over the 2-week dosing regimen. Drug concentrations for the branded and generic prednisolone acetate suspensions following expression from unshaken bottles were highly variable (overall relative SDs of 16.8% and 20.3%, respectively), with mean concentrations for both falling significantly below the declared concentration for drops expressed at the beginning of the 2-week dosing regimen and significantly above the declared concentration for drops expressed

  14. Ultrasound-assessed perirenal fat is related to increased ophthalmic artery resistance index in HIV-1 patients

    PubMed Central

    2010-01-01

    Background The introduction of highly active antiretroviral therapy (HAART) has dramatically changed the prognosis of human immunodeficiency virus (HIV) infection, with a significant decline in morbidity and mortality. Changes in body fat distribution are a common finding in individuals with HIV infection being treated with antiretrovirals, and this condition (collectively termed lipodystrophy syndrome) is associated with depletion of subcutaneous fat, increased triglycerides and insulin resistance. Obesity, particularly visceral obesity, is associated with increased risk of cardiovascular disease. Therefore, estimating visceral fat distribution is important in identifying subjects at high risk for cardiovascular disease. The aim of our study was to evaluate whether perirenal fat thickness (PRFT), a parameter of central obesity, is related to ophthalmic artery resistance index (OARI), an index of occlusive carotid artery disease in HIV-1 infected patients. Methods We enrolled 88 consecutive HIV-1-infected patients receiving highly active antiretroviral therapy for more than 12 months, in a prospective cohort study. Echographically measured PRFT and OARI, as well as serum metabolic parameters, were evaluated. PRFT and OARI were measured by 3.75 MHz convex and 7.5 MHz linear probe, respectively. Results The means of PRFT and OARI in HIV-1-infected patients with visceral obesity was considerably higher than in patients without it (p < 0.0001 and p < 0.001, respectively). Using the average OARI as the dependent variable, total serum cholesterol level, HDL, triglycerides, glycemia, sex, blood pressure, age and PRFT were independent factors associated with OARI. A PRFT of 6.1 mm was the most discriminatory value for predicting an OARI > 0.74 (sensitivity 78.9%, specificity 82.8%). Conclusions Our data indicate that ultrasound assessment of PRFT may have potential as a marker of increased endothelial damage with specific involvement of the ocular vascular region in HIV-1

    Purpose: To evaluate the 1-year safety of lifitegrast ophthalmic solution 5.0% in patients with dry eye disease compared with placebo. Methods: SONATA (Safety Of a 5.0% coNcentrATion of lifitegrAst ophthalmic solution) was a multicenter, randomized, prospective, double-masked, placebo-controlled phase 3 study (NCT01636206). Adults (≥18 years) with dry eye disease (Schirmer test score ≥1 and ≤10 mm; corneal staining score ≥2.0) were randomized 2:1 to lifitegrast ophthalmic solution 5.0% or placebo twice daily for 360 days. The primary objective was percentage and severity of treatment-emergent adverse events (TEAEs). Secondary objectives were ocular safety measures: corneal fluorescein staining, drop comfort, best-corrected visual acuity, slit-lamp biomicroscopy, and intraocular pressure over 7 visits. Exploratory objectives included concentration of lifitegrast in plasma. Results: The safety population comprised 331 participants (220 lifitegrast; 111 placebo). There were no serious ocular TEAEs. Overall, 53.6% of participants receiving lifitegrast experienced ≥1 ocular TEAE versus 34.2% in the placebo group; most TEAEs were mild to moderate in severity. Rates of discontinuation because of TEAEs were 12.3% (lifitegrast) versus 9.0% (placebo). The most common (>5%) TEAEs occurring in either treatment group were instillation site irritation (burning), instillation site reaction, visual acuity reduced, dry eye, and dysgeusia (change in taste). Ocular safety parameters for lifitegrast were similar to placebo. The mean plasma lifitegrast concentration at 360 days (n = 43) was below the limit of detection. There was no indication of systemic toxicity or localized infectious complications secondary to chronic immunosuppression. Conclusions: Lifitegrast ophthalmic solution 5.0% seemed safe and well tolerated in this study, with no unexpected adverse events. PMID:27055211

    The eyes are our window to the world and offer us an island of vision in the sea of darkness. Equally, the eyes are also a window to peep into what is going on in the milieu interior. Pregnancy is a natural state of physiological stress for the body. Each organ system of the body in a pregnant lady behaves at variation than in a non-pregnant state. A complex interplay exists between how the pregnancy affects the eye and how ocular physiology and pathology may lead to the modification of the management of pregnancy. Added to this is the effect of systemic conditions on the eye which gets modified by pregnancy. An awareness of the interaction of Ophthalmology and Obstetrics for the benefit of the mother and the child requires a basic understanding of these complex interactions. This article aims at presenting to the reader in a simplified and organized manner the common ophthalmic issues encountered in a pregnant woman, their management and the effect of various ophthalmic medication on the fetus.

    2002-01-01

    In a multicenter, open-label evaluation, 1098 patients with ocular itching and a history of perennial or seasonal allergic conjunctivitis instilled one drop of nedocromil sodium 2% twice daily in each eye. Ocular symptoms, signs, and global improvement were assessed at baseline and 1 month; satisfaction scores, quality-of-life variables, and adverse events were also recorded. Significant improvements from baseline (P<.012) occurred in mean severity scores for itching, burning, stinging, watering, swelling, tired eyes, dryness, gritty sensation, eye pain, foreign-body sensation, and light sensitivity. Physicians reported significant reductions (P<.0001) in bulbar conjunctival redness and swelling. Two thirds of patients (634/954) and three fourths of physicians (710/954) reported at least 75% improvement in overall condition after 1 month. The most common adverse events were burning (2.7%) and unpleasant taste (1.4%); headache (1.2%) and adverse events leading to discontinuation (1.3%) were rare. Patients reported significant improvement (P<.001) in their ability to perform daily activities; 65% were more satisfied with nedocromil than with their typical medication. Physicians would prescribe nedocromil again to 80% of the patients. Nedocromil sodium 2% twice daily was effective and safe for the treatment of symptoms of allergic conjunctivitis, significantly improving quality of life and producing high rates of user and physician satisfaction.

    Fungi may infect the cornea, orbit and other ocular structures. Species of Fusarium, Aspergillus, Candida, dematiaceous fungi, and Scedosporium predominate. Diagnosis is aided by recognition of typical clinical features and by direct microscopic detection of fungi in scrapes, biopsy specimens, and other samples. Culture confirms the diagnosis. Histopathological, immunohistochemical, or DNA-based tests may also be needed. Pathogenesis involves agent (invasiveness, toxigenicity) and host factors. Specific antifungal therapy is instituted as soon as the diagnosis is made. Amphotericin B by various routes is the mainstay of treatment for life-threatening and severe ophthalmic mycoses. Topical natamycin is usually the first choice for filamentous fungal keratitis, and topical amphotericin B is the first choice for yeast keratitis. Increasingly, the triazoles itraconazole and fluconazole are being evaluated as therapeutic options in ophthalmic mycoses. Medical therapy alone does not usually suffice for invasive fungal orbital infections, scleritis, and keratitis due to Fusarium spp., Lasiodiplodia theobromae, and Pythium insidiosum. Surgical debridement is essential in orbital infections, while various surgical procedures may be required for other infections not responding to medical therapy. Corticosteroids are contraindicated in most ophthalmic mycoses; therefore, other methods are being sought to control inflammatory tissue damage. Fungal infections following ophthalmic surgical procedures, in patients with AIDS, and due to use of various ocular biomaterials are unique subsets of ophthalmic mycoses. Future research needs to focus on the development of rapid, species-specific diagnostic aids, broad-spectrum fungicidal compounds that are active by various routes, and therapeutic modalities which curtail the harmful effects of fungus- and host tissue-derived factors.

    Purpose. To report the ocular findings in patients with hematopoietic malignancy with optic nerve involvement and abducens nerve palsy. Methods. The medical records of all cases of hematopoietic cancer with ophthalmic involvements seen in the Department of Ophthalmology of the National Center for Global Health and Medicine between 2009 and 2014 were reviewed. Results. Eight patients with hematopoietic cancer with optic nerve invasion or abducens nerve palsy were studied. The primary diseases were 3 cases of multiple myeloma, 1 case of acute lymphocytic leukemia, 1 case of follicular lymphoma, and 3 cases of AIDS-related lymphoma. Six cases had optic nerve invasion, 2 cases had abducens nerve palsy, and 1 case had optic nerve invasion of both eyes. The median visual acuity of eyes with optic nerve invasion was 0.885 logarithm of the minimum angle of resolution (logMAR) units. The final visual acuity of eyes with optic nerve invasion was 1.25 logMAR units, and that of those with sixth-nerve palsy was −0.1 logMAR units. Six cases died during the five-year follow-up period. An ophthalmic involvement in patients with hematopoietic cancer, especially AIDS-related lymphoma, was associated with poor prognosis. Conclusion. Because ophthalmic involvement in patients with hematopoietic malignancy has a poor prognosis, an early diagnosis of the cancers by the ophthalmologic findings by ophthalmologists could improve the prognosis.

    Terminal respiratory secretions (TRS) or "death rattle" is a common symptom in the dying patient. Current practice for the prevention and treatment of TRS involves the use of oral, sublingual, transdermal, or parenteral anticholinergic medications. A retrospective chart review of patients admitted to a hospice inpatient unit for terminal care and treated with sublingual atropine 1% ophthalmic drops for TRS was conducted. A total of 19 of 22 patients treated with atropine had documented reduction or resolution of TRS. This study suggests that atropine 1% ophthalmic drops administered sublingually are a reasonable option for the management of TRS. Problematic cardiac or central nervous system symptoms were not found in the present study. Results should aid hospice programs who are seeking guidance on the management of TRS with atropine 1% ophthalmic drops.

    Various ophthalmic complications affecting the anterior and posterior segments have been identified due to lightning strike. We report the first case of an indirect lightning-induced full thickness macular hole formation in the UK as evidenced by slit lamp examination and optical coherence tomography (OCT) scan in a 77-year-old woman presenting with sudden visual loss in her right eye and thermal skin injury affecting her scalp. Her best corrected visual acuities were LogMAR 0.46 and 0.12 in the right and left eyes, respectively. There were no other ocular manifestations observed in either eye. She was initially managed conservatively with non-steroidal anti-inflammatory drug eye drops but surgery was later advised due to minimal changes in the visual acuity and macular hole on follow-up. OCT scanning is important in diagnosing macular holes, which usually warrant surgical intervention. PMID:25827914

    Objective The aim of this study was to evaluate the effects of cyclosporine ophthalmic emulsion 0.05% on ocular surface staining and visual performance in patients with dry eye. Methods This was a single-center, 6-month, open-label, Phase IV study. Patients with bilateral dry eye disease and a symptom score of ≥2 on the Ocular Discomfort and 4-Symptom Questionnaire, an Ocular Surface Disease Index score of >12, at least one eye with Schirmer’s score <10 mm/5 minutes, and central corneal staining graded as ≥2 on the Ora Calibra™ Corneal and Conjunctival Staining Scale were enrolled. Cyclosporine ophthalmic emulsion 0.05% (Restasis®) was instilled twice daily in each eye. The primary efficacy endpoints were ocular surface staining and visual function at 6 months. Secondary outcome measures included Schirmer’s test, tear film breakup time, symptoms, and adverse events. Results A total of 40 patients with the mean age of 59.4 years (range, 40–78 years) were enrolled; 35 (87.5%) were female and 37 (92.5%) completed the study. At 6 months, inferior corneal, central corneal, total corneal, and total ocular surface fluorescein staining were significantly improved from baseline in both eyes (P<0.001). Patient responses on the Ocular Surface Disease Index showed significant improvement in blurred vision and visual function related to reading, driving at night, working with a computer or bank machine, and watching television (P≤0.041). At 6 months, 35.1% of patients achieved ≥5 mm improvement and 18.9% achieved ≥10 mm improvement in the average eye Schirmer score. Mean tear film breakup time improved by >50% in both eyes (P>0.001). Patients reported significant improvement in ocular discomfort and dry eye symptoms (P<0.001). No patients discontinued treatment because of stinging or any other ocular adverse event. Conclusion Dry eye patients with difficulties with day-to-day visual function demonstrated improvement in both signs and symptoms of dry eye and

    With a lifetime risk of 1% and 700 new cases per year, Non-Hodgkin lymphoma (NHL) is the seventh most frequent type of cancer in Denmark. The incidence of NHL has increased considerably in Western countries over the last decades; consequently, NHL is an increasing clinical problem. Ophthalmic lymphoma, (lymphoma localized in the ocular region, i.e. eyelid, conjunctiva, lacrimal sac, lacrimal gland, orbit, or intraocularly) is relatively uncommon, accounting for 5%-10% of all extranodal lymphomas. It is, however, the most common orbital malignancy. The purpose of this thesis was to review specimens from all Danish patients with a diagnosis of ophthalmic lymphoma during the period 1980-2005, in order to determine the distribution of lymphoma subtypes, and the incidence- and time trends in incidence for ophthalmic lymphoma. Furthermore, an extended analysis of the most frequent subtype, extranodal marginal zone lymphoma (MALT lymphoma), was done to analyse clinical factors and cytogenetic changes with influence on prognosis. A total of 228 Danish patients with a biopsy-reviewed verified diagnosis of ocular adnexal-, orbital-, or intraocular lymphoma were identified. We found that more than 50% of orbital- and ocular adnexal lymphomas were of the MALT lymphoma subtype, whereas diffuse large B-cell lymphoma (DLBCL) predominated intraocularly (Sjo et al. 2008a). Furthermore, lymphoma arising in the lacrimal sac was surprisingly predominantly DLBCL (Sjo et al. 2006). Incidence rates were highly dependent on patient age. There was an increase in incidence rates for the whole population from 1980 to 2005, corresponding to an annual average increase of 3.4% (Sjo et al. 2008a). MALT lymphoma arising in the ocular region was found in 116 patients (Sjo et al. 2008b). One third of patients had a relapse or progression of disease after initial therapy and relapses were frequently found at extra-ocular sites. Overall survival, however, was not significantly poorer for patients

    Herpes zoster ophthalmicus occurs when the latent varicella zoster virus (VZV) reactivates in the trigeminal ganglion and ophthalmic branch of the trigeminal nerve. In the elderly, there is a sharp increase in the tendency of secondary skin bacterial infections occurrence due to the deterioration of capabilities of self-care and changed sanitation. We present a case of patient who developed phlegmon of the orbit, which resulted with complete unilateral blindness. Varicella zoster virus infection in the elderly may have a severe course due to the progressive weakening of the immune system related to the age. Moreover, skin lesions around the eye socket require special care in prevention of bacterial superinfections due to the extremely high risk of life-threatening complications or disability. Neuralgia resistant to pharmacological treatment present in the course of ophthalmic zoster and difficulty in caring about skin lesions predispose to the occurrence of complications. PMID:26759550

    Coddington's equations can be used to eliminate the oblique astigmatic error in the design of ophthalmic lens of spherical or other conicoidal surfaces. But it is difficult to get satisfactory result in the designing of the nonconic aspheric ophthalmic lens. In this paper we present an efficient approach based on optimization of aspheric coefficients, which enables the design program to obtain the minimum aberrations. Many higher order coefficients of aspheric surfaces can easily result in inflection point, which increases the difficulty in manufacturing. We solved the problem by taking it as one of the optimization constraints. The design of nonconic aspheric ophthalmic lens could also make the spectacle lenses well thinner in thickness and well flatter in shape than the design of spherical ophthalmic lens and other conicoidal ophthalmic lens. Damped least square methods are used in our design. Aspherical myopia ophthalmic lenses, aspherical hypermetropic lenses and cataract lenses were designed. Comparisons of design examples' results are given.

    2015-05-01

    The halo effect is a very problematic visual artifact occurring in extended depth of focus or multi-focal ophthalmic lenses such as e.g. intra-ocular (after cataract surgery) or contact lenses when used in dark illumination conditions. This artifact is generated due to surface structures added on top of those lenses in order to increase their depth of focus or to realize multiple focal lengths. In this paper we present novel solution that can resolve this major problem of ophthalmic lenses. The proposed solution involves modification to the surface structure that realizes the extended depth of focus. Our solution is fabricated and numerically and experimentally validated also in preliminary in-vivo trials.

    Abusive head trauma includes any nonaccidental injury inflicted to a child's head and body. It is often characterized by, but not limited to, the repetitive acceleration-deceleration forces with or without blunt head impact. It has a mortality rate of 30%, and 80% of survivors experience permanent neurologic damage. In this case series, we hypothesize that bedside ultrasonography can be useful in the identification of retinal injuries that are consistent with abusive head trauma. Ocular manifestations of abusive head trauma are identified by dilated ophthalmic examination showing retinal hemorrhages that are too numerous to count, multilayered, and extending to the periphery. Traumatic retinoschisis, splitting of the retinal layers with or without blood accumulating in the intervening space, is exclusive for abusive head trauma in infants without a history of significant cerebral crush injury. Direct visualization of intraocular structures is difficult when the eyelids are swollen shut or when dilatation must be delayed. We present a series of 11 patients with brain injuries who underwent ophthalmic point-of-care ultrasonography that revealed traumatic retinoschisis on average 60 hours earlier than direct ophthalmic visualization. Dilated ophthalmic examinations and autopsy reports confirmed retinoschisis and other forms of retinal hemorrhages that were too numerous to count, multilayered, and extending to the periphery in all 11 patients. One patient did not have a dilated ophthalmic examination; however, traumatic retinoschisis and retinal hemorrhages were confirmed on autopsy. Ocular point-of-care ultrasonography is a promising tool to investigate abusive head trauma through the identification of traumatic retinoschisis and retinal hemorrhages when pupillary dilatation and direct ophthalmic examination is delayed.

    This exploratory clinical trial aims to assess the effect on visual acuity and central corneal thickness of an unpreserved hypertonic ophthalmic solution containing sodium chloride (5%) and sodium hyaluronate, in patients with chronic corneal edema caused by endothelial disease reducing their visual acuity. Twenty patients were enrolled and treated with the hypertonic solution (1 to 2 drops per eye, 4 times a day over 28 days). Progression of visual acuity (ETDRS score) and corneal thickness (ultrasonic pachymetry) was measured from baseline (without treatment) through the treatment period (Day 7 and Day 28). The analyses were performed on 18 patients (Full Analysis Set [FAS] population). The causes of corneal edema were Fuchs endothelial dystrophy in 10 cases and post-cataract surgery endothelial decompensation in 8 patients. The mean visual acuity values for the FAS population compared between baseline (Day-7) and one week of treatment (Day+7) show a significant 5-point VA improvement (P<0.001 paired Wilcoxon test). For corneal thickness, there was also a significant decrease (P=0.033 paired Wilcoxon test). Functional improvement was observed at 28 days of instillation. No adverse events were recorded during the clinical study. In conclusion, the unpreserved hyperosmolar solution containing sodium chloride and sodium hyaluronate significantly improved ETDRS visual acuity after one week of use. In this clinical trial, the solution also showed excellent tolerability results.

    Purpose We aimed to evaluate the feasibility of using a modified Schirmer test to determine the increase in tear volume after administration of 3% diquafosol ophthalmic solution (diquafosol 3%) in dry eye patients. Patients and methods A randomized, multicenter, prospective, double-blind clinical study recruited 50 qualified subjects. They received diquafosol 3% in one eye and artificial tears in the other eye. The study protocol comprised a screening and treatment procedure completed within 1 day. The Schirmer test was performed on closed eyes three times a day. The primary efficacy end points were the second Schirmer test scores 10 minutes after the single dose. Secondary end points were the third Schirmer test scores 3 hours and 40 minutes after the single dose and the symptom scores prior to the second and third Schirmer tests. Results According to the Schirmer test, 10 minutes after administration, diquafosol 3% significantly increased tear volume compared to artificial tears. Diquafosol 3% and artificial tears both showed significant improvements in the symptom scores compared to baseline. However, there was no significant difference in the symptoms score between diquafosol 3% and artificial tears. Conclusion The modified Schirmer test can detect a minute change in tear volume in dry eye patients. These findings will be useful in the diagnosis of dry eye, assessment of treatment benefits in daily clinical practice, and the development of possible tear-secreting compounds for dry eye.

    2016-03-01

    Ophthalmic Viscosurgical Devices (OVDs) in clinical setting are a major health risk factor for potential endotoxin contamination in the eye, due to their extensive applications in cataract surgery for space creation, stabilization and protection of intraocular tissue and intraocular lens (IOL) during implantation. Endotoxin contamination of OVDs is implicated in toxic anterior syndrome (TASS), a severe complication of cataract surgery that leads to intraocular damage and even blindness. Current standard methods for endotoxin contamination detection utilize rabbit assay or Limulus amoebocyte lysate (LAL) assays. These endotoxin detection strategies are extremely difficult for gel-like type devices such as OVDs. To overcome the endotoxin detection limitations in OVDs, we have developed an alternative optical detection methodology for label-free and real-time sensing of bacterial endotoxin in OVDs, based on fiber-optic Fourier transform infrared (FO-FTIR) transmission spectrometry in the mid-IR spectral range from 2.5 micron to 12 micron. Endotoxin contaminated OVD test samples were prepared by serial dilutions of endotoxins on OVDs. The major results of this study revealed two salient spectral peak shifts (in the regions 2925 to 2890 cm^-1 and 1125 to 1100 cm^-1), which are associated with endotoxin in OVDs. In addition, FO-FTIR experimental results processed using a multivariate analysis confirmed the observed specific peak shifts associated with endotoxin contamination in OVDs. Thus, employing the FO-FTIR sensing methodology integrated with a multivariate analysis could potentially be used as an alternative endotoxin detection technique in OVD.

    Ophthalmic ultrasound is an invaluable tool that provides quick and noninvasive evaluation of the eye and the orbit. It not only allows the clinicians to view structures that may not be visible with routine ophthalmic equipment or neuroimaging techniques but also provides unique diagnostic information in various ophthalmic conditions. In this article, the basic principles of ophthalmic ultrasound and examination techniques are discussed. Its clinical application is illustrated through a variety of ocular pathologic abnormalities (eg, narrow angles, ciliary body tumor, detached retina, choroidal melanoma, and papilledema).

    Objective This study aimed to establish the clinical characteristics of patients with glaucoma attending eye care facilities in Botswana, and management of glaucoma among patients who received care in these facilities. The study also aimed to calculate the number of new diagnoses of glaucoma within the glaucoma service. Design A prospective, hospital-based, observational study. Setting A multicentre study was undertaken in government-run eye departments in Botswana from June to August 2012. Participants All patients with a diagnosis of glaucoma attending clinics at seven study sites were invited to participate. Outcome measures Examination findings, diagnosis and management were extracted from individual patient-held medical charts. Sociodemographic characteristics, patient knowledge and understanding of glaucoma were assessed through face-to-face interviews. In addition, details of outpatient attendances for 2011 were collected from 21 government-run hospitals. Results The majority of the 366 patients interviewed had a diagnosis of primary glaucoma (86.6%). The diagnoses were mainly made by ophthalmologists (48.6%) and ophthalmic nurses (44.0%). Many patients (38.5%) had been symptomatic for over 6 months before visiting an eye clinic. The mean presenting intraocular pressure was 28.2 mm Hg (SD 11.9 mm Hg). Most follow-up patients (79.2%) had not received surgery, however, many (89.5%) would accept surgery. Only 11.5% of participants had heard of glaucoma prior to diagnosis. Many participants (35.9%) did not understand glaucoma after being diagnosed. The majority (94.9%) of living first-degree relatives had never been examined. The number of newly diagnosed glaucoma cases for 2011 in the south of the country was 14.1/100 000; 95% CI (12.0 to 16.5), in the north it was 16.2/100 000; 95% CI (13.8 to 19.0). Conclusions Glaucoma is a significant burden that presents challenges to ophthalmic services in Botswana. Many patients have limited understanding

    Carbonic anhydrase inhibitors are a common cause of normal anion gap metabolic acidosis; however, development is less commonly associated with ophthalmic administration of these agents. We report a case of a premature neonate who was being treated at our institution with betaxolol, dorzolamide, and latanoprost ophthalmic products for suspected bilateral congenital glaucoma. In addition, the patient was also receiving caffeine, ursodiol, and acidified liquid human milk fortifier. The patient developed a normal anion gap metabolic acidosis, and both dorzolamide ophthalmic solution and the acidified human milk fortifier were considered potential causes. Upon discontinuation of the dorzolamide ophthalmic solution and the switching of liquid human milk fortifiers, the normal anion gap metabolic acidosis gradually resolved. As a result of the pH and acidity, the acidified liquid human milk fortifier is thought to be associated with an anion gap acidosis; therefore, dorzolamide is suspected to be the primary cause of a normal gap acidosis. This case demonstrates that systemic effects can occur with ophthalmic administration of dorzolamide in a premature neonate. Ophthalmic agents should not be overlooked as a potential cause of systemic toxicity. PMID:27453705

    Carbonic anhydrase inhibitors are a common cause of normal anion gap metabolic acidosis; however, development is less commonly associated with ophthalmic administration of these agents. We report a case of a premature neonate who was being treated at our institution with betaxolol, dorzolamide, and latanoprost ophthalmic products for suspected bilateral congenital glaucoma. In addition, the patient was also receiving caffeine, ursodiol, and acidified liquid human milk fortifier. The patient developed a normal anion gap metabolic acidosis, and both dorzolamide ophthalmic solution and the acidified human milk fortifier were considered potential causes. Upon discontinuation of the dorzolamide ophthalmic solution and the switching of liquid human milk fortifiers, the normal anion gap metabolic acidosis gradually resolved. As a result of the pH and acidity, the acidified liquid human milk fortifier is thought to be associated with an anion gap acidosis; therefore, dorzolamide is suspected to be the primary cause of a normal gap acidosis.

    Background: Neurofibromatosis type 2 (NF2) is an autosomal dominant syndrome with a frequency of 1 in 25,000 live births and a penetrance of almost 100% by the sixth decade of life. The main tumors occurring in NF2 patients are bilateral vestibular schwannomas, other peripheral, cranial and spinal nerve schwannomas, intracranial and intraspinal meningiomas, ependymomas, and gliomas. Case Description: We report the case of a 6-year-old boy who presented with a 1-month history of nausea and recurrent vomiting. Physical examination was positive for ataxic gait and left-sided facial nerve palsy. Family history was positive for NF2 in the patient's father and paternal uncle. Magnetic resonance imaging brain revealed a solid enhancing lesion arising from the right cerebellar cortex, which was effacing the fourth ventricles and causing hydrocephalus. Craniotomy and excision of the lesion were performed. Histopathology report confirmed the diagnosis to be desmoplastic medulloblastoma. Based on the patients’ subsequent history and family history, he was diagnosed to be a case of NF2. Conclusion: This is the first case of medulloblastoma occurring in a patient with NF2 and raises the possibility of an association between medulloblastoma and NF2. PMID:26539318

    2015-05-01

    Diquafosol ophthalmic solution 3 % (Diquas(®)) is a P2Y2 receptor agonist that promotes tear fluid and mucin secretion and is currently approved in Japan and South Korea for the treatment of dry eye. In randomized, double-blind, multicentre trials in patients with dry eye, significantly greater improvements in fluorescein and rose bengal staining scores were seen with diquafosol ophthalmic solution 3 % than with placebo, and diquafosol ophthalmic solution 3 % was noninferior to sodium hyaluronate ophthalmic solution 0.1 % in terms of the improvement in the fluorescein staining score and more effective than sodium hyaluronate ophthalmic solution 0.1 % in terms of the improvement in the rose bengal staining score. The efficacy of diquafosol ophthalmic solution 3 % in the treatment of dry eye was maintained in the longer term, with improvements also seen in subjective dry eye symptoms, and was also shown in a real-world setting. Diquafosol ophthalmic solution 3 % also demonstrated efficacy in various specific dry eye disorders, including aqueous-deficient dry eye, short tear film break-up time dry eye, obstructive meibomian gland dysfunction, dry eye following laser in situ keratomileusis surgery and dry eye following cataract surgery, as well as in contact lens wearers and visual display terminal users. Diquafosol ophthalmic solution 3 % was generally well tolerated in patients with dry eye, with eye irritation the most commonly reported adverse event. In conclusion, diquafosol ophthalmic solution 3 % is a useful option for the treatment of dry eye.

    A 27-year-old white woman presented with enophthalmos in the right eye. The visual acuity was 20/20 in both eyes. External examination showed 7 mm of enophthalmos of the right eye with deepened superior palpebral sulcus compared with the left eye. After Valsalva maneuver, the right eye became 4-mm exophthalmic compared with the left eye. Extraocular movements were full. There was no palpable orbital mass or diplopia. MRI showed diffuse enhancing intraconal orbital and nasopharyngeal masses consistent with venous malformations in the right orbit. Systemic evaluation revealed bluish vascular lesions on the hard and soft palates, and the pretibial area of her right leg. These findings were suggestive of blue rubber bleb nevus syndrome. The patient was observed, and her clinical findings remained stable for 12 months. Enophthalmos can be a rare initial presentation of blue rubber bleb nevus syndrome and patients with ophthalmic involvement should undergo systemic evaluation including gastrointestinal, dermatologic, and otorhinolaryngologic examination.

    The authors have presented in two previous articles the graphic solutions resembling Tscherning ellipses, for spherical as well as for aspherical ophthalmic lenses free of astigmatism or power error. These solutions were exact, inasmuch as they were based on exact ray tracing, and not third-order theory as frequently done. In this paper sphero-cylindrical lenses are now analyzed, also using exact ray tracing. The functional dependence of the astigmatism and the power error for these lenses is described extensively.

  4. Detection of Ophthalmic Acid in Serum from Acetaminophen-Induced Acute Liver Failure Patients Is More Frequent in Non-Survivors

    Background/Aim Acetaminophen (APAP) hepatotoxicity is related to the formation of N-acetyl-p-benzoquinone imine (NAPQI), which is detoxified through conjugation with reduced glutathione (GSH). Ophthalmic acid (OA) is an analogue of GSH in which cysteine is replaced with 2-aminobutyrate. Metabolomics studies of mice with APAP-induced acute liver failure (APAP-ALF) identified OA as a marker of oxidative stress and hepatic GSH consumption. The aim of the current study was to determine whether OA is detectable in APAP-ALF human patients either early (day 2) or late (day 4) and whether OA levels were associated with in-hospital survival in the absence of liver transplant. Methods Serum samples from 130 APAP-ALF patients (82 survivors, 48 non-survivors) were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and correlated with clinical data from the United States Acute Liver Failure Study Group (US ALFSG) Registry (2004–2011). Results Survivors had significantly lower admission bilirubin (4.2 vs. 5.7 mg/dl) and lactate levels (3.3 vs. 6.5 μmol/l, p<0.05 for all). During the first 7 days of the study, survivors were less likely to require mechanical ventilation (55% vs. 88%), vasopressor support (9.8% vs. 67%) or renal replacement therapy (26% vs. 63%, p< 0.001 for all). Non-survivors were more likely to have detectable OA levels early (31% vs. 15%, p = 0.034) and late (27% vs. 11%, p = 0.02). However there were no significant differences in mean OA levels between non-survivors and survivors (early 0.48 vs. 0.36, late 0.43 vs. 0.37, P > 0.5 for all). Conclusion OA was detectable more frequently in APAP-ALF non-survivors but mean OA levels were not associated with survival. The routine clinical administration of N-acetyl cysteine could replenish GSH levels and prevent OA production. PMID:26407170

    The International Association for the Study of Pain (IASP 2011) defines neuropathic pain as “the pain caused by an injury or disease of the somatosensory portion of the nervous system”. The central neuropathic pain is defined as “the pain caused by an injury or disease of the central somatosensory central nervous system”, whereas the peripheral neuropathic pain is defined as “the pain caused by an injury or disease of the peripheral somatosensory nervous system” [1]. The peripheral neuropathy describes any affection of the peripheral nervous system. The etiology is vast, there being a number of over 100 possible causes, which causes the global morbidity rate to reach approximately 2.4%. The chronic nature of the pain superposes the everyday routine and leads to the high intake of medication for pain alleviation. The number of cases of neuroplasia has always increased today. This disturbing diagnosis which can potentiate the signs and symptoms of peripheral neuropathy as well as reduce and limit the treatment options associated with neuropathies. The treatment presupposes a multidisciplinary approach, while the solution to prevent complications involves the control of risk factors and pathophysiological treatment. Chemotherapy-induced peripheral neuropathy (CPIN) is a significant disabling symptom that is tightly connected to the administration of neurotoxic cytostatic agents used for the treatment of neoplasia. CPIN compromises the quality of life and produces pain or discomfort [2]. I have sought to produce a presentation of the medicated and physical-kinetic treatment options that have proved their effectiveness during clinical studies or random trials and can be applied to cancer patients presenting with symptoms associated with peripheral neuropathy, namely with neuropathic pain, and support it with arguments.

    Purpose To study the variability of the ophthalmic phenotype in Kniest dysplasia. Kniest dysplasia is an inherited disorder associated with defects in type II collagen and characterised by short-trunked dwarfism, kyphoscoliosis, and enlarged joints with restricted mobility. Other features include marked hand arthropathy, cleft palate, hearing loss, and ocular abnormalities (myopia, abnormal vitreous, and high risk of developing retinal detachment). Methods Data from eight unrelated individuals with a clinical and molecular diagnosis of Kniest dysplasia are reported. Clinical assessment included an audiogram and ophthalmological examination in all but one patient who died in the immediate postnatal period. Sanger sequencing of the COL2A1 gene was performed. Results Six of the seven patients tested were high myopes with one patient being an emmetrope. Bilateral quandratic cataracts and subluxed lenses were noted in one subject. Variable but abnormal vitreous architecture was observed in all seven individuals tested. Six of the seven patients had significant hearing impairment and five of the seven patients exhibited clefting abnormalities. One patient had bilateral retinal detachments in his twenties. Six dominant disease-causing COL2A1 variants were detected. In three cases, testing of parental samples revealed that the disease-causing variant was not present in either parent. Conclusion The ophthalmic features in Kniest dysplasia are very similar to those in other disorders of type II collagen such as Stickler syndrome. It is likely that different type II collagenopathies have a similar level of ocular morbidity and regular ophthalmologic examination is recommended. Kniest dysplasia is associated with heterozygous COL2A1 mutations that are frequently de novo. PMID:25592122

    Hyperhidrosis is a debilitating condition that affects approximately 2.8% of the population. Patients experience reduced quality of life and face significantly impairment in social interactions and occupational activities. Primary focal hyperhidrosis stems from neurogenic overactivity involving normal eccrine glands, while secondary generalized hyperhidrosis is due to any one of a number of causes. Patient history, physical examination, and appropriate laboratory tests should rule out secondary causes of hyperhidrosis. For primary hyperhidrosis, rate and volume of sweat production and quality of life assessment can be determined.

    The 40 years since St Christopher's Hospice opened has witnessed a burgeoning international interest in palliative care. Its key characteristics comprise a focus on the whole-person (physical, psychological, social, and spiritual), patient-centeredness (partnership with and empowerment of the patient and family), openness and honesty in communication, an acceptance of the inevitability of death coupled with improvement in the quality of life, multi-professional teamwork integrated with community (volunteer) involvement. Although much has been achieved, much remains to be done. Both in resource-poor countries and in more wealthy ones, the scope of palliative care has changed. Initially in the United Kingdom, palliative care was mostly limited to cancer patients but now strenuous efforts are being made to extend coverage to other patient groups, e.g., those with end-stage heart disease or renal failure. In India, with a dearth of chronic care facilities, palliative care services increasingly embrace those with chronic disability as well as progressive end-stage disease. In Sub-Saharan Africa, the devastating impact of AIDS is having a major impact on the development and delivery of palliative care. To maximize the benefits of limited financial and other resources, a strategic approach is necessary. The World Health Organization emphasizes three essential foundation measures: health service policy, public awareness and professional education, and drug availability. However, at the end of the day, if we are truly to honor Cicely Saunders, palliative care must remain a movement with momentum, combining creative charisma with inevitable bureaucratic routinization.

    A variety of diseases cause chest pain. Some entities such as acute coronary syndrome, aortic dissection, and pulmonary embolism are Life-threatening and immediate medical interventions may be required. Acute coronary syndrome is a disease due to disruption of plaque in coronary arteries. The echocardiography can be utilized to diagnose these situation by detecting wall motion abnormalities. Aortic dissection occurs when a tear in the inner wall of the aorta causes blood to flow between the layers of the wall and force the layers apart. The diagnosis can be made by pointing out the intimal flap by echocardiographic examination. A pulmonary embolism is a sudden blockage in a lung artery, which usually caused by a blood clot in a deep vein thrombosis. The echocardiography can prove the existence of pulmonary hypertension and right ventricular over loading. When one performs echocardiography in patients with chest pain in the emergency room, it is important to observe patient's condition, physical findings, and the electrocardiogram. The life-threatening diseases such as acute coronary syndrome, aortic dissection and pulmonary embolism should be considered in the first. If these lethal diseases are ruled out, every possibility including diseases other than cardiovascular disease must be considered. In the emergency echocardiography, incomplete knowledge and skills may lead misdiagnosis and patient's life is threatened. Thus, expert sonographer should perform the examination. The most important issue is to save the patients not to complete the echocardiographic study in this situation.

    Spencer, L M; Spencer, G R

    1990-03-01

    A classification of ocular disorders has been developed that is both comprehensive and easy to use. Each disorder was assigned a unique abbreviation and cross referenced to the International Classification of Diseases, 9th edition (ICD-9). Ophthalmic procedures, medications, and other terms were similarly standardized and abbreviated. The result is a system of ophthalmic terminology that improves the quality of the medical record, facilitates ICD-9 coding, and makes computer data entry faster and more accurate. The system is published as a standard text with companion handbook. A computer program that uses the system also has been developed. PMID:2336279

  13. Cerebral Angiographic Findings of Cosmetic Facial Filler-related Ophthalmic and Retinal Artery Occlusion

    PubMed Central

    2015-01-01

    Cosmetic facial filler-related ophthalmic artery occlusion is rare but is a devastating complication, while the exact pathophysiology is still elusive. Cerebral angiography provides more detailed information on blood flow of ophthalmic artery as well as surrounding orbital area which cannot be covered by fundus fluorescein angiography. This study aimed to evaluate cerebral angiographic features of cosmetic facial filler-related ophthalmic artery occlusion patients. We retrospectively reviewed cerebral angiography of 7 patients (4 hyaluronic acid [HA] and 3 autologous fat-injected cases) showing ophthalmic artery and its branches occlusion after cosmetic facial filler injections, and underwent intra-arterial thrombolysis. On selective ophthalmic artery angiograms, all fat-injected patients showed a large filling defect on the proximal ophthalmic artery, whereas the HA-injected patients showed occlusion of the distal branches of the ophthalmic artery. Three HA-injected patients revealed diminished distal runoff of the internal maxillary and facial arteries, which clinically corresponded with skin necrosis. However, all fat-injected patients and one HA-injected patient who were immediately treated with subcutaneous hyaluronidase injection showed preserved distal runoff of the internal maxillary and facial arteries and mild skin problems. The size difference between injected materials seems to be associated with different angiographic findings. Autologous fat is more prone to obstruct proximal part of ophthalmic artery, whereas HA obstructs distal branches. In addition, hydrophilic and volume-expansion property of HA might exacerbate blood flow on injected area, which is also related to skin necrosis. Intra-arterial thrombolysis has a limited role in reconstituting blood flow or regaining vision in cosmetic facial filler-associated ophthalmic artery occlusions. PMID:26713062

    This paper describes hitherto developed drug forms for topical ocular administration, that is, eye drops, ointments, in situ gels, inserts, multicompartment drug delivery systems, and ophthalmic drug forms with bioadhesive properties. Heretofore, many studies have demonstrated that new and more complex ophthalmic drug forms exhibit advantage over traditional ones and are able to increase the bioavailability of the active substance by, among others, reducing the susceptibility of drug forms to defense mechanisms of the human eye, extending contact time of drug with the cornea, increasing the penetration through the complex anatomical structure of the eye, and providing controlled release of drugs into the eye tissues, which allows reducing the drug application frequency. The rest of the paper describes recommended in vitro and in vivo studies to be performed for various ophthalmic drugs forms in order to assess whether the form is acceptable from the perspective of desired properties and patient's compliance.

    Preservatives are an important component of ophthalmic preparations, providing antimicrobial activity in the bottle and preventing decomposition of active drug. Often underrecognized, however, are the significant cytotoxic effects of preservatives associated with long-term therapy and especially use of multiple preserved drugs. The most common preservatives in ophthalmic preparations for glaucoma and surface eye disease-benzalkonium chloride (BAK), chlorobutanol, sodium perborate, and stabilized oxychloro complex (SOC)-were reviewed. Compared with other preservatives, SOC caused the least amount of damage to rabbit corneal epithelial cells. BAK has demonstrated cytotoxic effects in cell culture, as well as in animal and human studies. Physicians should consider treatment with new-generation preparations containing low-risk preservatives such as SOC, especially in patients receiving multiple ophthalmic medications.

Robots offer a number of potential improvements over unassisted human hands, such as tremor filtration, scaling of motion, enhanced dexterity in confined spaces, and extremely high precision. Several designs and prototypes have recently been introduced for use in ophthalmic surgery and they have been tested in animal models. Ophthalmic surgical robots have the potential to expand our treatment armamentarium, reduce complication rates, and hold future promise to treat surgical conditions that remain incurable today.

    High-frequency transducers, up to 35-50 MHz, are widely used in ophthalmic echography to image fine eye structures. Phased-array techniques are not practically applicable at such a high frequency, due to the too small size required for the single transducer element, and mechanical scanning is the only practical alternative. At present, all ophthalmic ultrasound systems use focused single-element, mechanically scanned probes. A good probe positioning and image evaluation feedback requires an image refresh-rate of about 15-30 frames per second, which is achieved in commercial mechanical scanning probes by using electromagnetic motors. In this work, we report the design, construction, and experimental characterization of the first mechanical scanning probe for ophthalmic echography based on a small piezoelectric ultrasound motor. The prototype probe reaches a scanning rate of 15 sectors per second, with very silent operation and little weight. The first high-frequency echographic images obtained with the prototype probe are presented.

    INTRODUCCIÓN: el loxoscelismo se debe a la inoculación de un conjunto de enzimas proteolíticas por la mordedura de la araña Loxosceles. Puede tener una expresión local, sin embargo, la forma viscerocutánea o sistémica tiene una evolución grave. Se presenta el primer caso de la variante sistémica en una mujer embarazada. CASO CLÍNICO: mujer con embarazo normoevolutivo de 28 semanas. Después de estar expuesta a un ambiente semirrural, presentó placa plana eritematosa en el glúteo derecho, con aumento de la temperatura e hiperestesia local. Fue hospitalizada para administrarle antibióticos parenterales, por considerarse que se trataba de la picadura de un insecto. A las cuatro horas se incrementó el dolor y la paciente desarrolló deshidratación e hipotensión severas hasta llegar al choque, por lo que se inició tratamiento con cristaloides, aminas vasopresoras y protección de la vía aérea. Se realizó operación cesárea, de la que se obtuvo un niño, y se efectuó desbridación en el glúteo derecho. El diagnóstico fue loxoscelismo sistémico, por lo que se administró el antiveneno específico. La paciente fue egresada a los dos meses.

    The poor bioavailability and therapeutic response exhibited by conventional ophthalmic solutions due to rapid precorneal elimination of the drug may be overcome by the use of a gel system. The present work describes the formulation and evaluation of an ophthalmic delivery system containing an antibacterial agent, enoxacin, based on the concept of ophthalmic sustained gel, in which 2-hydroxypropyl-beta-cyclo-dextrin (HP-beta-CD) was used as a penetration enhancer in combination with hydroxypropylmethylcellulose (Methocel F4M) which acted as a vehicle. The developed formulation was therapeutically efficacious, nonirritant, and provided sustained release of the drug over 8 h period in vitro and 7 h period in vivo. The developed system is a viable alternative to conventional eye drops.

  5. Ophthalmic striated muscle neoplasms.

    Rhabdomyosarcoma, the most common primary malignant childhood orbital tumor, is composed of neoplastic striated muscle cells (rhabdomyoblasts) in various stages of differentiation and in patterns suggestive of neoplastic analogs of normal muscle embryogenesis. Orbital rhabdomyosarcoma is most commonly seen in children and adolescents, the average age of onset of symptoms being 7.8 years. The tumor usually presents as a rapidly evolving exophthalmos, often associated with drooping of the upper eyelid. A mass is palapable in only 25% of cases, loss of central vision at the time of presentation is uncommon, and laboratory studies are often of little help in diagnosis. The best diagnostic aid is a high index of suspicion whenever one sees a rapidly progressive exophthalamos in a child. Orbital rhabdomyosarcoma is almost always of the embryonal type, believed to originate in the orbital soft tissues from undifferentiated pluripotential embryonic mesenchyme. In the past, orbital exenteration has been the primary therapy. Review of 162 literature cases of orbital rhabdomyosarcoma, generally treated by unassisted surgery, revealed that only 25% of the patients survived 3 or more years. Recently, it has been shown that radiation therapy, alone or combined with chemotherapy, can be successful. A multidisciplinary approach, utilizing surgery, radiation therapy and chemotherapy has also been advocated. Both approaches appear to offer greater survival than unassisted orbital exenteration. The possibility of primary radiation therapy is extremely promising; if it becomes increasingly effective, a mutilating surgical procedure may become obsolete.

    We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

    Turnbull, Andrew M J; Emsley, Elizabeth S

    2014-01-01

    Video documenting is increasingly used in ophthalmic training and research, with many ophthalmologists routinely recording their surgical cases. Although this modality represents an excellent means of improving technique and advancing knowledge, there are major ethical and legal considerations with its use. Informed consent to record is required in most situations. Patients should be advised of any risk of identification and the purpose of the recording. Systems should be in place to deal with issues such as data storage, withdrawal of consent, and patients requesting copies of their recording. Privacy and security of neither patients nor health care professionals should be compromised. Ownership and distribution of video recordings, the potential for their use in medical litigation, the ethics and legality of editing and the impact on surgeon performance are other factors to consider. Although video recording of ophthalmic surgery is useful and technically simple to accomplish, patient safety and welfare must always remain paramount.

    Background Effective control of intraocular pressure is predicated upon patient compliance with pharmacotherapy. We compared patient adherence and persistence with two new ocular hypotensive formulations, using real-world utilization data. Methods This observational cohort study employed pharmacy claims data from the Source® Lx (Wolters Kluwer Pharma Solutions) database. Patients with an initial (index) prescription for topical bimatoprost 0.01% or travoprost Z (April to June 2011) and no claim for ophthalmic prostaglandin or prostamide analogs within the previous 18 months were identified. Treatment adherence was expressed as proportion of days covered with study medication during the first 365 days after the index prescription. Treatment persistence with study medication was assessed over the first 12 months using Kaplan–Meier survival analyses, allowing a maximum 30-day gap for prescription refill. Treatment status was determined monthly over this period. Results A total of 12,985 patients were assessed for treatment adherence, and 10,470 for treatment persistence. Adherence was better with bimatoprost 0.01% than with travoprost Z (mean proportion of days covered 0.540 versus [vs] 0.486, P<0.001), and more patients showed high adherence (proportion of days covered >0.80) with bimatoprost 0.01% than travoprost Z (29.1% vs 22.3%, P<0.001). Continuous 12-month persistence was higher with bimatoprost 0.01% than with travoprost Z (29.5% vs 24.2%, P<0.001). At month 12, more patients were on treatment with bimatoprost 0.01% than travoprost Z (48.8% vs 45.7%, P<0.01). Similar findings were demonstrated in cohorts of ocular hypotensive treatment-naïve patients, branded latanoprost switchers, and older patients (age ≥65 years), and after inclusion of patient characteristics as covariates. Conclusion For patients with glaucoma or ocular hypertension, bimatoprost 0.01% offers compliance advantages over travoprost Z. PMID:24868144

    The human ocular surface, consisting of the cornea and conjunctiva, is colonized by an expansive, diverse microbial community. Molecular-based methods, such as 16S rRNA sequencing, has allowed for more comprehensive and precise identification of the species composition of the ocular surface microbiota compared to traditional culture-based methods. Evidence suggests that the normal microbiota plays a protective immunological role in preventing the proliferation of pathogenic species and thus, alterations in the homeostatic microbiome may be linked to ophthalmic pathologies. Further investigation of the ocular surface microbiome, as well as the microbiome of other areas of the body such as the oral mucosa and gut, and their role in the pathophysiology of diseases is a significant, emerging field of research, and may someday enable the development of novel probiotic approaches for the treatment and prevention of ophthalmic diseases.

    Purpose Accidental sharps injuries are a potential route for transmission of blood-borne infection to healthcare workers. Ophthalmic staff in particular are at risk of sustaining such injuries due to the microsurgical nature of the speciality. Forthcoming European Union legislation aimed at reducing sharps injuries requires the development of risk-based sharps policy. The authors believe that this is the first study to assess the risks of sharps injuries and their management specific to ophthalmic practice within the European Union. Methods A retrospective review of all reported sharps injuries across three eye units in the UK over a period of 6 years was undertaken. Data were analysed to determine the circumstances surrounding the injury, occupation of the injured person, and whether appropriate actions were taken following incidents. Results A total of 68 sharps injuries were reported over the 6-year period. Nurses sustained 54.4% (n=37) of needlestick injuries, doctors 39.7% (n=27), and allied healthcare staff 5.9% (n=4). In all 51.5% (n=35) of sharps injuries occurred in the operating theatre, 30.9% (n=21) in the outpatient clinic, 13.2% (n=9) on the ophthalmic ward, and 4.4% (n=3) in unspecified locations. There was a median rate of 1.3 sharps injuries per 1000 surgical procedures per year and a range of 0.4–3.5 per 1000. Conclusions This study demonstrates the need to raise awareness of the unique risks of sharps injuries in ophthalmic practice. This is necessary in order to develop speciality-specific policy that promotes strategies to reduce such injuries, enhances the accuracy of reporting of such events, and provides guidance for appropriate management.

    Nowadays refractive errors in the human eye affect approximately 10% of world's population, decreasing vision acuity and life quality. However a simple common solution is the use of an adequate ophthalmic lens. Due to the importance of ophthalmic lenses, the best measurement equipment is required for testing, these days experimental and commercial apparatus are available but with the possibility of improvement. We present a method to measure spherical and cylindrical power in ophthalmic lenses. The system uses an equation obtained from lateral amplification concept and Gauss formula to make calculations. Also an experimental setup is presented for the measurement of ophthalmic lens from -20 diopters to 20 diopters in the case of spherical lenses, and from -6 diopters to 6 diopters in the case of cylindrical lenses. The setup contains a reference object, the lens to be tested and a digital camera connected to a computer with software designed in LabVIEW for the data processing. Satisfactory preliminary results were obtained according to ISO 8598.

    Triple A syndrome (Allgrove syndrome) is a rare, autosomal recessive disorder characterized by adrenocorticotropic hormone resistant adrenal insufficiency, alacrima, achalasia of the esophageal cardia, progressive neurological degeneration and occasionally autonomic instability. We report the ophthalmic manifestations in 2 siblings from a consanguineous family with this syndrome. A routine ophthalmic examination showed absence of palpebral portion of lacrimal gland, dry eyes and sluggish pupillary reflexes in both eyes of these patients. Both of these patients had achalasia cardia while the boy additionally had increased serum cortisol levels. Topical ocular lubricants were prescribed for both of them and Heller's cardiomyotomy with fundus plication was done for achalasia. These cases would create an awareness of this rare condition in ophthalmology in addition to suggesting its management. PMID:17595484

    A single-center, open-label study consisting of two visits over the course of approximately 2 weeks was conducted to evaluate the efficacy of Retaine™ ophthalmic emulsion in improving the signs and symptoms of dry eye. Forty-two subjects were enrolled and received 1-2 drops twice daily of Retaine™ beginning at the first visit (day 1) and ending at the second visit. Subjects were instructed to complete a symptomatology diary twice daily prior to drop instillation through the morning of the second visit. Ocular sign and symptom assessments, visual acuity procedures, and comfort assessments were conducted during both visits. A statistically significant reduction was observed in mean breakup area on the second visit between the predose time and the postdose time (P=0.026). On the second visit, subjects had significantly less corneal fluorescein staining in the superior (P=0.002), central (P=0.017), corneal sum (P=0.011), and all ocular regions combined (P=0.038) than on the first visit. On the second visit, statistically significant reductions in dryness (P<0.001), grittiness (P=0.0217), ocular discomfort (P=0.0017), and all symptoms (P<0.001) were also seen as measured by the Ora Calibra™ Ocular Discomfort and 4-Symptom Questionnaire (0-5 scale). Subjects reported a statistically significant improvement in their abilities to work with a computer at night (P=0.044). Mean drop comfort scores ranged from 1.29-1.81 on the Ora Calibra™ 0-10 Drop Comfort Scale, on which 0 is very comfortable and 10 is very uncomfortable. Retaine™ demonstrates promising results as a novel artificial tear option for individuals suffering from dry eye. The unique mechanism of action of Retaine™ provides enhanced comfort and improves the quality of life of dry eye subjects while reducing the ocular signs of dry eye. PMID:25709384

    2012-01-01

    Tuberculosis is a universal mimicker and thus could be a differential diagnosis of any osteolytic lesion. Bone biopsy is crucial in these cases for culture and histological proof of tuberculous infection. This is a case report of two paediatric patients with unusual presentations of tuberculosis. One patient presented with knee pain and had imaged findings of an osteolytic lesion at the epiphysis. Interval scan showed spread of the lesion through the physis to the metaphyseal region. The second patient presented with hip pain and an osteolytic lesion of the acetabulum. He was subsequently found to have involvement of the brain and spine as well. Both patients were diagnosed with tuberculosis by bone biopsy for culture and pathological examination. They were treated successfully with antituberculous medications without chronic sequelae. These two patients showed that early recognition and prompt treatment are critical for management of tuberculosis to avoid chronic sequelae. PMID:23087272

    1993-01-01

    Congenital rubella syndrome has a wide variety of severe ophthalmic and systemic complications. A worldwide rubella epidemic from 1963 to 1965 affected thousands of infants. This is a 20 year follow up study of patients with congenital rubella syndrome analysing the prevalence of ophthalmic disorders, associated systemic problems, and correlations among these defects. The authors statistically analysed 125 cases of congenital rubella seen in the Mayo clinic ophthalmology department over a 32 year interval. Most patients were young adults. Ocular disease was the most commonly noted disorder (78%), followed by sensorineural hearing deficits (66%), psychomotor retardation (62%), cardiac abnormalities (58%), and mental retardation (42%). Multiorgan disease was typical (88%). Ocular disease and hearing loss were frequently associated (53% had both) but not significantly correlated. A similar association existed between ocular and cardiac disease. Cataracts and microphthalmia were significantly correlated with poor visual acuity (each p < 0.0001). Glaucoma was significantly correlated with cataracts (p = 0.0002) and microphthalmia (p = 0.0024) but not poor visual acuity. Four patients with microphthalmia developed late onset glaucoma. No significant association was found between gestational age at time of maternal infection and the incidence of individual ocular conditions. However, several cardiac disorders were significantly associated with gestational age. Although new cases of congenital rubella are rare, surviving victims continue to challenge the ophthalmic and medical communities with a wide range of ocular and systemic disorders. PMID:8318483

    Abstract Objective To describe the characteristics of patients who presented to outpatient sport and exercise medicine clinics with concussion. Design Retrospective chart review of electronic medical records. Setting Three specialized sport and exercise medicine clinics in London, Ont. Participants A total of 283 patients presenting with concussion. Main outcome measures Data collected included demographic variables (age and sex), sport participation at the time of injury, previous medical history (including history of concussion), Post-Concussion Symptom Scale (PCSS) scores, and return-to-play (RTP) variables (delay and outcome). Results The mean age of patients presenting for care was 17.6 years; 70.9% of patients were younger than 18 years of age (considered pediatric patients); 58.8% of patients were male; and 31.7% of patients had a previous history of concussion. The main sports associated with injury were hockey (40.0%), soccer (12.6%), and football (11.7%). Return to play was granted to 50.9% of patients before the 3-week mark and 80.2% of patients before 8 weeks. Total PCSS scores (maximum score was 132) and neck scores (part of the PCSS, maximum score was 6) were significantly higher in adults compared with pediatric patients (36.2 vs 27.6, P = .02, and 1.8 vs 1.2, P = .02, respectively). A significant difference was seen in RTP, with pediatric patients returning earlier than adults did (P = .04). This difference was not seen when comparing males with females (P = .07). Longer duration of follow-up did not influence RTP outcomes. Previous history of concussion was associated with restriction from contact or collision sports (P < .001). Conclusion Given the age and sex variability found in this study, as well as in previous published reports, it is important to manage each patient individually using current best available practice strategies to optimize long-term outcomes.

  1. Unique Presentation of Hematuria in a Patient with Arterioureteral Fistula

    Active extravasation via an arterioureteral fistula (AUF) is a rare and life-threatening emergency that requires efficient algorithms to save a patient's life. Unfortunately, physicians may not be aware of its presence until the patient is in extremis. An AUF typically develops in a patient with multiple pelvic and aortoiliac vascular surgeries, prior radiation therapy for pelvic tumors, and chronic indwelling ureteral stents. We present a patient with a left internal iliac arterial-ureteral fistula and describe the evolution of management and treatment algorithms based on review of the literature. PMID:27293944

    We prospectively evaluated the initial presenting symptoms in 261 patients with Zollinger-Ellison syndrome (ZES) over a 25-year period. Twenty-two percent of the patients had multiple endocrine neoplasia-type 1 (MEN-1) with ZES. Mean age at onset was 41.1 +/- 0.7 years, with MEN-1 patients presenting at a younger age than those with sporadic ZES (p < 0.0001). Three percent of the patients had onset of the disease < age 20 years, and 7% > 60 years. A mean delay to diagnosis of 5.2 +/- 0.4 years occurred in all patients. A shorter duration of symptoms was noted in female patients and in patients with liver metastases. Abdominal pain and diarrhea were the most common symptoms, present in 75% and 73% of patients, respectively. Heartburn and weight loss, which were uncommonly reported in early series, were present in 44% and 17% of patients, respectively. Gastrointestinal bleeding was the initial presentation in a quarter of the patients. Patients rarely presented with only 1 symptom (11%); pain and diarrhea was the most frequent combination, occurring in 55% of patients. An important presenting sign that should suggest ZES is prominent gastric body folds, which were noted on endoscopy in 94% of patients; however, esophageal stricture and duodenal or pyloric scarring, reported in numerous case reports, were noted in only 4%-10%. Patients with MEN-1 presented less frequently with pain and bleeding and more frequently with nephrolithiasis. Comparing the clinical presentation before the introduction of histamine H2-receptor antagonists (pre-1980, n = 36), after the introduction of histamine H2-receptor antagonists (1981-1989, n = 118), and after the introduction of proton pump inhibitors (PPIs) (> 1990, n = 106) demonstrates no change in age of onset; delay in diagnosis; frequency of pain, diarrhea, weight loss; or frequency of complications of severe peptic disease (bleeding, perforations, esophageal strictures, pyloric scarring).

    Background: Intraoperative neuromonitoring (IONM) is used for real-time evaluation of neuronal tracts and reflexes in the anesthetized patient, when a neurologic exam is not possible. Changes in IONM signals forewarn of possible neurological deficit. This real-time feedback allows for immediate alterations in therapeutic technique by the treating physician. Transcranial visual evoked potentials are not reliable for evaluating the integrity of the prechiasmatic visual system. Electroretinography (ERG) has been used in animal models for monitoring retinal ischemia and can be used in humans as well to monitor for prechiasmatic ischemia of the retinae and optic nerves. Case Description: We present a case where ERG signal amplitude and latency changed during ophthalmic arteriovenous fistula embolization, resulting in an intraprocedural decision to refrain from embolization of additional arterial pedicles to preserve vision. After awakening from general anesthesia, the patient had no deficits in visual acuity or field testing, but did complain of transient pain with eye movement that resolved the next day and worsened with episodes of blood pressure elevation. Conclusions: ERG may be helpful for detecting prechiasmatic ischemic changes during endovascular procedures and may provide early warning signs to the surgeon before the onset of permanent retinal damage. Further investigation is needed to assess the utility of ERG monitoring during the treatment of orbital and periorbital vascular lesions. PMID:23607062

    Objectives To assess the prevalence of psychosocial distress (depression, anxiety, somatization, and perceived stress) in a consecutive sample of patients presenting with voice concerns, and to qualitatively analyze patient comments on challenges associated with voice problems. Study Design Cross-sectional study. Methods New patients presenting to a multidisciplinary voice clinic with voice concerns were invited to participate. Respondents (n = 197) completed the Brief Symptom Inventory 18 item scale (BSI-18), the 4-item Perceived Stress Scale (PSS-4), and the Voice Handicap Index 10 item scale (VHI-10). Qualitative analysis was performed of responses to an open-ended question about challenges associated with a voice problem. Results Approximately one-third (32%) of patients met strict case criteria for depression, anxiety, and/or somatic concerns based on the BSI-18. The majority of these patients had no prior diagnosis of depression or anxiety, and degree of distress was not predicted by type of voice-related diagnosis. Perceived stress was elevated among female patients (p=0.02). As expected, scores on the VHI-10 were indicative of concurrent voice-related handicap (mean 19.5, standard deviation 9.4). In qualitative analysis of responses regarding challenges associated with a voice problem, 19 themes were identified (e.g., threat to occupational functioning). Conclusions These findings identify a high prevalence of multiple types of distress among patients with voice disorders, representing an opportunity to provide more comprehensive care to this patient population.

    Abstract Objective To discover the frequency of psychosocial and other diagnoses occurring at the end of a visit when patients present to their FPs with concerns about fatigue. Design Cross-sectional study of patient-FP encounters for fatigue. Setting Ten FP practices in southwestern Ontario. Participants A total of 259 encounters involving 167 patients presenting to their FPs between March 1, 2006, and June 30, 2010, with concerns about fatigue. Main outcome measures The frequency of psychological and social diagnoses made at the end of visits, and whether diagnoses were made by FPs at the end of the visits versus whether the code for fatigue remained. The associations between patient age, sex, fatigue presenting with other symptoms, or the presence of previous chronic conditions and the outcomes was tested. Results Psychosocial diagnoses were made 23.9% of the time. Among psychosocial diagnoses made, depressive disorder and anxiety disorder or anxiety state were diagnosed more often in women (P = .048). Slightly less than 30% of the time, the cause of patients’ fatigue remained undiagnosed at the end of the encounter. A diagnosis was made more often in men. Conclusion Causes of fatigue frequently remain undiagnosed; however, when there is a diagnosis, psychosocial diagnoses are common. Therefore, it would be appropriate for FPs to screen for psychosocial issues when their patients present with fatigue, unless some other diagnosis is evident. Depression and anxiety could be considered particularly among female patients with fatigue. PMID:27521412

  10. The need for skull radiography in patients presenting for CT

    SciTech Connect

    Tress, B.M.

    1983-01-01

    One thousand patients had both CT of the head and a conventional skull series of radiographs. Radiographic findings were abnormal in 250 patients (25%), but only 64 patients (6.4%) had diagnostically significant abnormalities at radiography that were not detected by CT. If the 163 patients who presented after acute trauma were excluded from the series, only 39 (4.7%) of the remaining patients had radiographically significant abnormal findings that were not seen at CT, and only two (0.2%) of these abnormalities could not be diagnosed by a lateral skull radiograph alone. In only five patients (0.5%) was the management actively changed because an abnormaltiy that was detected at skull radiography was not detected at CT. Thus, in nontrauma patients who have stroke, epilepsy, dementia, or non-specific symptoms without focal signs, or have recently undergone craniotomy, and who have been referred for CT, skull radiographs are not justified. In the patient with a history and findings that are strongly suggestive of a pathological disorder anywhere other than in the sella turcica, cerebello-pontine angle, and paranasal sinuses, only the lateral skull radiograph should be obtained after CT, and only if CT is equivocal.

    This study was conducted to identify the event characteristics of mass gatherings that predict patient presentation rates held in a southeastern US university community. We conducted a retrospective review of all event-based emergency medical services (EMS) records from mass gathering patient presentations over an approximate 23 month period, from October 24, 2009 to August 27, 2011. All patrons seen by EMS were included. Event characteristics included: crowd size, venue percentage filled seating, venue location (inside/outside), venue boundaries (bounded/unbounded), presence of free water (i.e., without cost), presence of alcohol, average heat index, presence of climate control (i.e., air conditioning), and event category (football, concerts, public exhibitions, non-football athletic events). We identified 79 mass gathering events, for a total of 670 patient presentations. The cumulative patron attendance was 917,307 persons. The patient presentation rate (PPR) for each event was calculated as the number of patient presentations per 10,000 patrons in attendance. Overdispersed Poisson regression was used to relate this rate to the event characteristics while controlling for crowd size. In univariate analyses, increased rates of patient presentations were strongly associated with outside venues [rate ratio (RR) = 3.002, p < 0.001], unbounded venues (RR = 2.839, p = 0.001), absence of free water (RR = 1.708, p = 0.036), absence of climate control (RR = 3.028, p < 0.001), and a higher heat index (RR = 1.211 per 10-unit heat index increase, p = 0.003). The presence of alcohol was not significantly associated with the PPR. Football events had the highest PPR, followed sequentially by public exhibitions, concerts, and non-football athletic events. In multivariate models, the strong predictors from the univariate analyses retained their predictive significance for the PPR, together with heat index and percent seating.

    Large population-based health administrative databases, clinical registries, and data linkage systems are a rapidly expanding resource for health research. Ophthalmic research has benefited from the use of these databases in expanding the breadth of knowledge in areas such as disease surveillance, disease etiology, health services utilization, and health outcomes. Furthermore, the quantity of data available for research has increased exponentially in recent times, particularly as e-health initiatives come online in health systems across the globe. We review some big data concepts, the databases and data linkage systems used in eye research-including their advantages and limitations, the types of studies previously undertaken, and the future direction for big data in eye research.

    Cytomegalovirus (CMV) is the most common viral infection in solid organ transplant recipients. Symptomatic infection usually presents with fever, pneumonia, colitis, or cytopenia. We describe a case of symptomatic CMV infection in a liver transplant recipient presenting with atypical symptoms of only persistent nausea and vomiting, in the absence of classical symptoms and signs; thus, highlighting the importance of high index of suspicion of CMV in immunocompromised patients, keeping in mind the high morbidity and mortality associated with this disease.

    The presenting features of functionally active pituitary tumours depend on the specific hormone which is overproduced. Growth hormone (GH) producing tumours usually present with the clinical manifestations of acromegaly due to excessive GH secretion or symptoms resulting from mass effects of the enlarging tumour. The changes in physical features and the increase in tumour size are usually insidiously slow and therefore, recognition of the disease is delayed. In this report two patients with acromegaly are described with an atypical presentation due to acute onset of symptoms. The first patient presented with central diabetes insipidus. The diagnosis acromegaly was made on physical examination. The second patient presented with a generalized seizure during sleep. On CT-scanning a large tumour protruding into the left temporal lobe connected to the pituitary gland was seen. Immunohistochemistry of the tumour after partial transcranial resection confirmed the clinical diagnosis of acromegaly. At a later stage transsphenoidal resection of the pituitary tumour was performed with full recovery and without loss of pituitary function. PMID:10218386

    Dengue infection is a major public health problem, affecting the general population in Southeast Asia. Hematologic aberrations in dengue infection include atypical lymphocytosis, coagulopathy, and predominant thrombocytopenia. Bleeding and other presentations in 30 Thai patients with dengue infection during an endemic season (2003) are presented. A review of the clinical presentation of these patients was performed. All had fever as a chief complaint. The three most common complaints were fever (100%), vomiting (90%), and cough (90%), respectively. Concerning bleeding, only eight cases (26.6%) had signs of bleeding. Those manifestations included petechiae (seven cases, 23.3%) and melena (one case, 3.3%). Skin bleeding (petechiae) due to thrombocytopenia is the most common bleeding manifestation in dengue infection. However, physicians should not overlook bleeding from other less common sites such as the gastrointestinal tract and genitourinary tract.

    The basic idea in this study relates to the interesting research problem to employ with the knowledgeable pharmacy staff N-acetylcarnosine (NAC) in the developed suitable compounded prodrug ophthalmic preparations, which are currently used for the treatment of cataract and have antioxidant effect, in order to provide the molecular support to one of the most popular beliefs of the growing market for the treatment of senile cataract in patients and animals with efficacious NAC drug formulations worldwide patented by the author. This work presents the progress in ocular NAC prodrug and codrug design and delivery in light of revealed ocular metabolic activities. There is a considerable interest in the ophthalmic codrug design including NAC prodrug based on the strategies to improve ophthalmic drug delivery of the active peptide principal L-carnosine through the sustained intraocular metabolic activation of a dipeptide while making it resistant to enzymatic hydrolysis. Novel approaches to ocular NAC drug delivery, developed by Innovative Vision Products, Inc. (IVP), aim at enhancing the drug bioavailability by ensuring a prolonged retention of the medication in the eye, and/or by facilitating transcorneal penetration. IVP team studied the effects of lubricant eye drops designed as 1% NAC prodrug of L-carnosine containing a mucoadhesive cellulose-based and corneal absorption promoters in a drug delivery system. The predicted responses of the corneal and conjunctival penetrations to the synergistic promoters are useful in controlling the extent and pathway of the ocular and systemic absorptions of instilled NAC prodrug in designed ophthalmic formulations thereof. Utility of peptidase enzyme inhibitors in the codrug formulation to modulate the transport and metabolism of NAC prodrug appears to be a promising strategy for enhancing dipeptide drug transport across the cornea.

    Background: Ophthalmic pterygium is a common benign lesion of unknown origin and the pathogenesis might be vision-threatening. This problem is often associated with exposure to solar light. Recent evidence suggests that potentially oncogenic viruses such as human papillomavirus and Epstein-Barr virus may be involved in the pathogenesis of pterygia. Expression of specific adenovirus genes such as E1A and E1B, which potentially have many functions, may contribute to their oncogenic activity as well as relevance to cellular immortalization. Objectives: For the first time, we aimed to investigate involvement of adenoviruses in pterygium formation. Patients and Methods: Fifty tissue specimens of pterygium from patients undergoing pterygium surgery (as cases), 50 conjunctival swab samples from the same patients and 10 conjunctival biopsy specimens from individuals without pterygium such as patients undergoing cataract surgery (as controls) were analyzed for evidence of adenovirus infection with polymerase chain reaction using specific primers chosen from the moderately conserved region of the hexon gene. Furthermore, β-globin primers were used to access the quality of extracted DNA. Data was analyzed using SPSS (version 16) software. Results: Of 50 patients, 20 were men and 30 women with mean age of 61.1 ± 16.9 years ranged between 22 and 85 years. All samples of pterygia had positive results for adenoviruses DNA with polymerase chain reaction, but none of the negative control groups displayed adenoviruses. The pterygium group and the control groups were β-globin positive. Direct sequencing of PCR products confirmed Adenovirus infection. Conclusions: Adenoviruses might act as a possible cause of pterygium formation and other factors could play a synergistic role in the development. However, further larger studies are required to confirm this hypothesis. PMID:26034543

    A 28-year-old man presented with a 2-week history of red eye, photophobia, pain and decreased visual acuity of the right eye. The ophthalmological examination revealed hypertensive non-granulomatous panuveitis, retinal vasculitis with focus of retinochoroiditis with pigmented central area suggestive of ocular toxoplasmosis in the active phase. He started treatment with azithromycin, pyrimethamine, topical steroids and measures for control of intraocular pressure. Serology for Toxoplasma gondii was positive and for HIV, negative. For headache and vomiting, he was hospitalised in order to exclude cerebral toxoplasma. The cerebral CT scan, MRI and lumbar puncture were negative and treatment was changed to pyrimethamine, sulfadiazine and prednisolone. For persistence of vomiting he started clindamycin with clinical and ophthalmological improvement. The patient is currently under prophylaxis with co-trimoxazol for 1 year, and maintains clinical improvement. This case illustrates the rarity of presentation of ocular toxoplasmosis, without cerebral in an immunocompetent patient. PMID:25270156

    BACKGROUND: With the advent of general practitioner fundholding, there has been growth in outreach clinics covering many specialties. The benefits and costs of this model of service provision are unclear. AIM: A pilot study aimed to evaluate an outreach model of ophthalmic care in terms of its impact on general practitioners, their use of secondary ophthalmology services, patients' views, and costs. METHOD: A prospective study, from April 1992 to March 1993, of the introduction of an ophthalmic outreach service in 17 general practices in London was undertaken. An ophthalmic outreach team, comprising an ophthalmic medical practitioner and an ophthalmic nurse, held clinics in the practices once a month. Referral rates to Edgware General Hospital ophthalmology outpatient department over one year from the study practices were compared with those from 17 control practices. General practitioners' assessments of the scheme and its impact on their knowledge and practice of ophthalmology were sought through a postal survey of all partners and interviews with one partner in each practice. Patient surveys were conducted using self-administered structured questionnaires. A costings exercise compared the outreach model with the conventional hospital ophthalmology outpatient clinic. RESULTS: Of 1309 patients seen by the outreach team in the study practices, 480 (37%) were referred to the ophthalmology outpatient department. The annual referral rate to this department from control practices was 9.5 per 10,000 registered patients compared with 3.8 per 10,000 registered patients from study practices. A total of 1187 patients were referred to the outpatient department from control practices. An increase in knowledge of ophthalmology was reported by 18 of 47 general practitioners (38%). Nineteen (40%) of 47 general practitioners took advantage of the opportunity for inservice training with the outreach team; they were more likely to change their routine practice for ophthalmic care

    Despite a paucity of data regarding both the incidence of ocular candidiasis and the utility of ophthalmic examination in critically ill patients, routine ophthalmic examination is recommended for critically ill patients with candidaemia. The objectives were to estimate the incidence of ocular candidiasis and evaluate whether ophthalmic examination influenced subsequent management of these patients. We conducted a ten-year retrospective observational study. Data were extracted for all ICU patients who were blood culture positive for fungal infection. Risk factors for candidaemia and eye involvement were quantified and details regarding ophthalmic examination were reviewed. Candida species were cultured in 93 patients. Risk factors for ocular candidiasis were present in 57% of patients. Forty-one percent of patients died prior to ophthalmology examination and 2% of patients were discharged before candidaemia was identified. During examination, signs of ocular candidiasis were only present in one (2.9%) patient, who had a risk factor for ocular candidiasis. Based on these findings, the duration of antifungal treatment for this patient was increased. Ocular candidiasis occurs rarely in critically ill patients with candidaemia, but because treatment regimens may be altered when diagnosed, routine ophthalmic examination is still indicated.

    Pycnodysostosis is a rare autosomal recessive disorder caused by mutations in the cysteine protease Cathepsin K gene located on chromosome 1q21. It has a well characterized skeletal phenotype which include short stature, generalized increased bone density with propensity of fractures, open calvarial sutures and fontanelle, dental abnormalities, obtuse mandibular angle, resorption of lateral end of clavicle, acro-osteolysis, and in some cases visceromegaly. Central nervous system involvement is very rare and porencephalic cysts has been reported only once, the cause being hypothesised to be an imbalance between the growing brain, its vascular supply and intraventricular fluid pressure. We had a patient with bilateral frontal lobe porencephalic cysts; the patient presenting with complex partial seizures. Cathepsins have been found to be involved in neurological diseases and role of proteases has been well established in gliosis. PMID:25002775

    In recent years, many pharmaceutical scientists have focused on developing the in situ gel-forming systems to overcome the poor bioavailability and therapeutic response exhibited by conventional ophthalmic solutions due to rapid pre-corneal elimination of the drug. The present work was to compare the systemic absorptions of ophthalmic ofloxacin in situ gel with the conventional ofloxacin eye drop after topical instillation to rabbit eyes by HPLC-MS/MS method and also determine the relative contribution of the nasal and the conjunctival mucosae to systemic ofloxacin absorption following topical instillation. The systemic AUC, Cmax, Tmax and Ke for ophthalmic in situ gel and ophthalmic solution after ocular instillation were 202.63±118.85 and 202.25±57.74 ng mL(-1) h, 54.22±28.31 and 48.4±25.97 ng mL(-1), 1.08±0.20 and 1.25±0.88 h, 0.0576±0.0207 and 0.0388±0.0248, respectively. And the values for the ratios of the AUC of anterior chamber of rabbit eye to blood plasma, AUCac/AUCpl, for ofloxacin conventional eye drop and in situ gel were 0.25 and 0.52, respectively. Statistic results showed that there was no significant difference in systemic absorption between the test groups and the reference groups (P>0.05) as both formulations have an AUCsa/AUCpl of 0.35. Therefore, the ophthalmic in situ gel may not decrease the drugs systemic absorption when administered in an equivalent dose as ophthalmic solutions into the rabbit eyes.

    Introduction: Brain tumors in children often involve the visual system, but most retrospective series are by neurologists or oncologists. In this study we highlight the ophthalmic findings of outpatient children with visual complaints and/or strabismus who, based on ophthalmic examination, were suspected to and confirmed to harbor intracranial space-occupying lesions by magnetic resonance imaging (MRI). Materials and Methods: Retrospective case series of children (less than 18 years) who for visual complaints and/or strabismus underwent cranial MRI at a referral eye hospital (2005–2012), which revealed intracranial space-occupying lesions. Exclusion criteria were known preexisting orbital or ocular trauma, ocular tumor, or neurological disease. Results: For 26 patients (3 months-17 years; mean 7 years; median 9 years; and 14 boys), the most common clinical presentation was decreased vision with disc pallor (10) or swelling (three). Other presentations were strabismus with disc pallor or swelling (four; two of which were left sixth nerve palsies), acquired esotropia with diplopia (three; one bilateral and two left sixth nerve palsies), acquired exotropia (four; two of which were bilateral third nerve palsies, one of which was left partial third nerve palsy, and one of which was associated with headache), nystagmus (one), and disc swelling with headache (one). Most lesions were in the sellar/suprasellar space (10), posterior fossa (six), or optic nerve/chasm (four). Conclusions: The majority of outpatient children diagnosed by ophthalmologists with intracranial space-occupying lesions presented with disc swelling or pallor in the context of decreased vision or strabismus. Two strabismus profiles that did not include disc swelling or pallor were acquired sixth nerve palsy and acquired exotropia (with ptosis (third nerve palsy), nystagmus, or headache). PMID:26180471

    2004-07-01

    Fast Spectral Optical Coherence Tomography (SOCT) technique is used to perform cross sectional and three-dimensional ophthalmic images. Static, real-time and 3-D in vivo images of the human cornea, lens, iris, corneo-scleral junction, retinal layers, optic disc and macula lutea are presented. The ophthalmic application of SOCT is promising because this technique ensures fast acquisition with relatively low optical power of incident light. All demonstrated images are obtained with the aid of SOCT instrument, which was constructed in the optical laboratory of medical physics group at Nicolaus Copernicus University (Torun, Poland). What is to our knowledge there are the first good quality (>90dB sensitivity) ophthalmic OCT images obtained by technique, which is different than time domain OCT.

    This article describes a simple Hartmann test data interpretation that can be used to evaluate the performance of ophthalmic lenses. Considering each spot of the Hartmann pattern such as a single test ray, using simple ray tracing analysis, it is possible to calculate the power values from the lens under test at the point corresponding with each spot. The values obtained by this procedure are used to plot the power distribution map of the entire lens. We present the results obtained applying this method with single vision, bifocal, and progressive lenses.

    Ableman, Thomas Benton; Newman, Steven A

    2016-04-01

    Head and neck malignancies with orbital involvement present difficult decisions to the treating physician. When the spread is perineural, the challenges are greater due to the incipient nature of the spread and the fact that the orbit can also be involved by centrifugal spread from the non-ophthalmic branches of the trigeminal nerve. The disease is often misdiagnosed and the subsequent delay in treatment results in worse outcomes. This article discusses the evaluation of the eye and the many facets of orbital involvement by perineural spread of malignancy including the treatment of complications. PMID:27123389

    Since the NIST dose to water standard for {sup 90}Sr/{sup 90}Y ophthalmic applicators was introduced, numerous sources have undergone calibration either at NIST or at the University of Wisconsin Accredited Dosimetry Calibration Laboratory (UWADCL). From 1997 to 2008, 222 of these beta-emitting sources were calibrated at the UWADCL, and prior reference source strength values were available for 149 of these sources. A survey of UWADCL ophthalmic applicator calibrations is presented here, demonstrating an average discrepancy of -19% with a standard deviation of {+-}16% between prior reference values and the NIST-traceable UWADCL absorbed dose to water calibrations. Values ranged from -49% to +42%.

    2012-01-01

    Ocular parasitosis in human is more prevalent in geographical areas where environmental factors and poor sanitary conditions favor the parasitism between man and animals. Lesions in the eye can be due to damage directly caused by the infectious pathogen, indirect pathology caused by toxic products, or the immune response incited by infections or ectopic parasitism. The epidemiology of parasitic ocular diseases reflects the habitat of the causative parasites as well as the habits and health status of the patient. An ocular examination may provide clues to the underlying disease/infection, and an awareness of the possibilities of travel-related pathology may shed light on an ocular presentation. This paper is a comprehensive review of the parasitic diseases of the eye. The majority of the clinically important species of parasites involved in eye infection are reviewed in this paper. Parasites are discussed by the disease or infection they cause.

    Objective and Importance When treating large unruptured ophthalmic artery (OA) aneurysms causing progressive blindness, surgical clipping is still the preferred method because aneurysm sac decompression may relieve optic nerve compression. However, endovascular treatment of OA aneurysms has made important progress with the introduction of stents. Although this development is welcomed, it also makes the choice of treatment strategy less straightforward than in the past, with the potential of missteps. Clinical Presentation A 56-year-old woman presented with a long history of progressive unilateral visual loss and magnetic resonance imaging showing a 20-mm left-sided OA aneurysm. Intervention Because of her long history of very poor visual acuity, we considered her left eye to be irredeemable and opted for endovascular therapy. The OA aneurysms was treated with stent and coils but continued to grow, threatening the contralateral eye. Because she failed internal carotid artery (ICA) balloon test occlusion, we performed a high-flow extracranial-intracranial bypass with proximal ICA occlusion in the neck. However, aneurysm growth continued due to persistent circulation through reversed blood flow in distal ICA down to the OA and the cavernous portion of the ICA. Due to progressive loss of her right eye vision, we surgically occluded the ICA proximal to the posterior communicating artery and excised the coiled, now giant, OA aneurysm. This improved her right eye vision, but her left eye was permanently blind. Conclusion This case report illustrates complications of the endovascular and surgical treatment of a large unruptured OA aneurysm. PMID:25485220

    Purpose We performed ophthalmic examinations, including optical coherence tomography (OCT), on a case diagnosed with hydranencephaly. Case Report This case involved a female infant born at the gestational age of 35 weeks and 4 days, with the birth weight of 2,152 g, who was one of monochorionic diamniotic twins, and the identical twin died in utero at the gestational age of 24 weeks. After that, examination by fetal echo indicated that she had microcephaly and ventriculomegaly. Postnatal magnetic resonance imaging (MRI) of her head indicated microcephaly and significant enlargement of the lateral ventricle on both sides, with no obvious signs of elevated intracranial pressure. The brain parenchyma of both sides of the frontal lobe, parietal lobe, and occipital lobe had marked thinning, yet that of the temporal lobe, basal ganglia, thalamus, brain stem, and cerebellum had been maintained. Moreover, no obvious hematoma or neoplastic lesions were observed. Ophthalmic examinations indicated that both of her eyes had slight light reflex, attributed to optic nerve atrophy. Examination by use of a hand-held OCT system indicated a layered structure of the retina and thinning of the ganglion cell layer. Flicker electroretinogram (ERG) examination by use of a hand-held ERG system indicated an almost normal wave. However, no clear visual reaction was observed when she was 10 months old. Conclusion Our findings in this case of hydranencephaly revealed that even though the outer layer functions of the patient's retina were maintained, extensive damage to her cerebral cortex resulted in poor visual function.

  18. Late presentation of acromegaly in medically controlled prolactinoma patients

    Summary Co-secretion of growth hormone (GH) and prolactin (PRL) from a single pituitary adenoma is common. In fact, up to 25% of patients with acromegaly may have PRL co-secretion. The prevalence of acromegaly among patients with a newly diagnosed prolactinoma is unknown. Given the possibility of mixed GH and PRL co-secretion, the current recommendation is to obtain an insulin-like growth factor-1 (IGF-1) in patients with prolactinoma at the initial diagnosis. Long-term follow-up of IGF-1 is not routinely done. Here, we report two cases of well-controlled prolactinoma on dopamine agonists with the development of acromegaly 10–20 years after the initial diagnoses. In both patients, a mixed PRL/GH-cosecreting adenoma was confirmed on the pathology examination after transsphenoidal surgery (TSS). Therefore, periodic routine measurements of IGF-1 should be considered regardless of the duration and biochemical control of prolactinoma. Learning points: Acromegaly can develop in patients with well-controlled prolactinoma on dopamine agonists. The interval between prolactinoma and acromegaly diagnoses can be several decades. Periodic screening of patients with prolactinoma for growth hormone excess should be considered and can 
lead to an early diagnosis of acromegaly before the development of complications.

    Background/Aim Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system. Effector T helper cells, mainly Th1 and Th17, cytotoxic T-cells, B-cells, macrophages, microglia, and the cytokines they secrete, are implicated in the initiation and maintenance of a deregulated immune response to myelin antigens and the ensuing immune-mediated demyelination. In this study, we investigated whether signature cytokines exist in MS patients at presentation to gain an insight into the underlying immunopathogenic processes at the early stage of the disease. Methods We collected serum and cerebrospinal fluid (CSF) samples from 123 patients at presentation, eventually diagnosed with MS or non-inflammatory (NIND) or inflammatory neurological diseases (IND) or symptomatic controls (SC). The levels of cytokines IFN-γ, TNF-α, TGF-β1, IL-2, IL-4, IL-6, IL-10 and IL-17 were measured, and cytokine ratios, such as Th1/Th2, Th1/Th17, and Type-1/Type-2, were calculated. All parameters were tested for their correlations with the intrathecal IgG synthesis. Results Cytokine levels in CSF were lower than in serum in all the patients, with the exception of IL-6. Serum or CSF cytokine levels of MS patients did not differ significantly from NIND or SC, with the exception of serum IFN-γ and TNF-α that were significantly higher in NIND. IND patients presented with the highest levels of all cytokines in serum and CSF, with the exception of serum IL-10 and CSF IL-17. MS patients had a significantly lower serum Th1/Th2 ratio compared to the NIND and IND groups, and significantly lower serum Type-1/Type-2, IFN-γ/IL-10 and CSF Th1/Th17 ratios compared to IND patients. MS patients had a significantly higher CSF IL-17/IL-10 ratio compared to IND patients. The IgG index was higher in MS patients compared to the control groups; the differences reached statistical significance between the MS and the NIND and SC groups.

    2015-07-01

    Antisynthetase syndrome (aSS) corresponds to an overlapping inflammatory myopathy identified by various myositis-specific autoantibodies (directed against tRNA-synthetases). Myocardial involvement in this condition is poorly described.From a registry of 352 aSS patients, 12 cases of myocarditis were retrospectively identified on the basis of an unexplained increase in troponin T/I levels associated with either suggestive cardiac magnetic resonance imaging (MRI) findings, nonsignificant coronary artery abnormalities or positive endomyocardial biopsy.The prevalence of myocarditis in aSS is 3.4% and was not linked to any autoantibody specificity: anti-Jo1 (n = 8), anti-PL7 (n = 3), and anti-PL12 (n = 1). Myocarditis was a part of the first aSS manifestations in 42% of the cases and was asymptomatic (n = 2) or revealed by an acute (n = 4) or a subacute (n = 6) cardiac failure. It should be noted that myocarditis was always associated with an active myositis. When performed (n = 11), cardiac MRI revealed a late hypersignal in the T1-images in 73% of the cases (n = 8). Half of the patients required intensive care. Ten patients (83%) received dedicated cardiotropic drugs. Steroids and at least 1 immunosuppressive drug were given in all cases. After a median follow-up of 11 months (range 0-84) 9 (75%) patients recovered whereas 3 (25%) developed a chronic cardiac insufficiency. No patient died.The prevalence of myocarditis in aSS is similar to that of other inflammatory myopathies. Although the prognosis is relatively good, myocarditis is a severe condition and should be carefully considered as a possible manifestation in active aSS patients.

    Behavior problems are among the most common concerns for veterinary clients, and veterinarians need to be comfortable diagnosing and treating these conditions. Knowledge of animal behavior by veterinarians is critical for effective treatment of behavior problems, recognition and diagnosis of medical conditions for which behavior signs prevail, proper handling of veterinary patients, prevention of abandonment and euthanasia, preservation of the companion animal-human bond, and prevention of mental suffering. Successful patient management requires taking a thorough behavioral history, understanding the mechanisms underlying behavior changes, developing appropriate treatment interventions, and, in some cases, pharmacologic therapy.

    Opitz, Dominick L.; Harthan, Jennifer S.

    2012-01-01

    AzaSite® (azithromomycin 1.0%) ophthalmic solution was approved in 2007 by the US Food and Drug Administration (FDA) as the first commercially available formulation of ophthalmic azithromycin for the treatment of bacterial conjunctivitis. AzaSite® utilizes a vehicle delivery system called DuraSite®, which stabilizes and sustains the release of azithromycin to the ocular surface, leading to a longer drug residence time, less frequent dosing, and an increase in patient compliance. AzaSite® is a broad spectrum antibiotic, effective against Gram-positive, Gram-negative, and atypical bacteria. AzaSite® has been studied for the treatment of ocular conditions beyond its clinical indication. A number of clinical studies have evaluated its efficacy and safety in the management of ocular conditions such as bacterial conjunctivitis and blepharitis on both the pediatric and adult populations. This article aims to evaluate the peer-reviewed published literature on the use of azithromycin 1.0% ophthalmic for current and possible future ophthalmic uses. PMID:23650453

    Ophthalmic changes have occurred in a subset of astronauts on International Space Station missions. Visual deterioration is considered the greatest human health risk of spaceflight. Affected astronauts exhibit higher concentrations of 1-carbon metabolites (e.g., homocysteine) before flight. We hypothesized that genetic variations in 1-carbon metabolism genes contribute to susceptibility to ophthalmic changes in astronauts. We investigated 5 polymorphisms in the methionine synthase reductase (MTRR), methylenetetrahydrofolate reductase (MTHFR), serine hydroxymethyltransferase (SHMT), and cystathionine β-synthase (CBS) genes and their association with ophthalmic changes after flight in 49 astronauts. The number of G alleles of MTRR 66 and C alleles of SHMT1 1420 both contributed to the odds of visual disturbances. Preflight dehydroepiandrosterone was positively associated with cotton wool spots, and serum testosterone response during flight was associated with refractive change. Block regression showed that B-vitamin status and genetics were significant predictors of many of the ophthalmic outcomes that we observed. In one example, genetics trended toward improving (P = 0.10) and B-vitamin status significantly improved (P < 0.001) the predictive model for refractive change after flight. We document an association between MTRR 66 and SHMT1 1420 polymorphisms and spaceflight-induced vision changes. This line of research could lead to therapeutic options for both space travelers and terrestrial patients. PMID:26316272

    We describe in this paper the current status of ophthalmic plastic and orbital surgery in Taiwan. Data were collected from the Bureau of National Health Insurance of Taiwan, the Bulletin of the Taiwan Ophthalmic Plastic and Reconstructive Society, and the Statistics Yearbook of Practicing Physicians and Health Care Organizations in Taiwan by the Taiwan Medical Association. We ascertained that 94 ophthalmologists were oculoplastic surgeons and accounted for 5.8% of 1621 ophthalmologists in Taiwan. They had their fellowship training abroad (most ophthalmologists trained in the United States of America) or in Taiwan. All ophthalmologists were well trained and capable of performing major oculoplastic surgeries. The payment rates by our National Health Insurance for oculoplastic and orbital surgeries are relatively low, compared to Medicare payments in the United States. Ophthalmologists should promote the concept that oculoplastic surgeons specialize in periorbital plastic and aesthetic surgeries. However, general ophthalmologists should receive more educational courses on oculoplastic and cosmetic surgery.

  7. Anatomy of the Ophthalmic Artery: Embryological Consideration

    PubMed Central

    There are considerable variations in the anatomy of the human ophthalmic artery (OphA), such as anomalous origins of the OphA and anastomoses between the OphA and the adjacent arteries. These anatomical variations seem to attribute to complex embryology of the OphA. In human embryos and fetuses, primitive dorsal and ventral ophthalmic arteries (PDOphA and PVOphA) form the ocular branches, and the supraorbital division of the stapedial artery forms the orbital branches of the OphA, and then numerous anastomoses between the internal carotid artery (ICA) and the external carotid artery (ECA) systems emerge in connection with the OphA. These developmental processes can produce anatomical variations of the OphA, and we should notice these variations for neurosurgical and neurointerventional procedures. PMID:27298261

    Eye inflammation, if untreated at right time poses the risk of vision loss. Several categories of drugs are available in the global market, but corticosteroids are still used for the treatment of ocular inflammation including anterior/ posterior uveitis, age related macular degeneration (AMD) and post cataract surgery inflammation. Although corticosteroids have well-documented side effects as compared to non steroidal anti-inflammatory drugs (NSAIDs), but they are still regarded as better anti-inflammatory agents for treating ocular inflammations. The prime concern with conventional formulations such as (ophthalmic solutions, suspensions, ointments) is low drug bioavailability due to precorneal barrier of the eye, tear turnover and rapid drainage of drug via nasolacrimal drainage and drug induced systemic toxicity. To overcome these limitations, various novel formulations of corticosteroids have been explored. These include nanoparticles, solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), nanomicelles, in-situ gels, iontophoresis, liposomes, nanoemulsions, microemulsions and ocular implants for the effective ophthalmic delivery of the corticosteroids. Topical nanocarriers have also been demonstrated to be promising vectors with potential application in the ophthalmic therapeutics. This review summarizes the clinical findings and patents on various corticosteroids as ocular pharmacotherapeutics. PMID:25020063

    The first beginnings of ophthalmic echography in Croatia started at the turn of the 1960s and 1970s. When the two largest medical institutions in Croatia, Sestre milosrdnice University Hospital (former Dr. Mladen Stojanović General Hospital) and Zagreb University Hospital Center, both in Zagreb, were supplied with ultrasonic diagnostic devices, Krautkrimer/ Siemens Echoophthalmograph and Echoophtalmograph 7200 MA Kretz, they had to start using the instruments. Some ophthalmologists working at these institutions embarked upon acquiring due education at home and abroad. In the mid-1970s, the first diagnostic laboratories were organized at the above mentioned clinical institutions in Zagreb. In the 1970s, two ophthalmologists received Doctor of Science (PhD) degree and veniam legendi. The first papers on echography in domestic professional literature were published in the early 1970s. Postgraduate study in ophthalmology for MS degree started at the School of Medicine, University of Zagreb in 1972. Soon, in 1975, lectures on ultrasonic diagnostics were introduced within the scope of this study. Participating in echographic courses and in SIDUO meetings abroad, some Croatian ophthalmologists became members and even members of the SIDUO Executive Board. The first course in ophthalmic echography as continuing medical education at the Zagreb School of Medicine was held in 1992. Ultrasound Division of the Croatian Ophthalmologic Society was organized in 1994 and 1998. The references accompanying this survey includes all papers on ophthalmic ultrasound published in Croatia and some abroad, thus representing Croatian echographic bibliography.

  10. A survey of pre-operative fasting regimens before regional ophthalmic anaesthesia in three regions of the United Kingdom.

    A postal and telephone survey of the practice of fasting before regional ophthalmic anaesthesia with and without sedation was sent to 50 hospitals in three regions of the United Kingdom. Responses were received from 100% of hospitals. In most hospitals (58%), local anaesthetic blocks were performed by both surgeons and anaesthetists, with surgeons alone providing ophthalmic anaesthesia in only 14%. Eighty-six per cent of hospitals surveyed had a formal policy regarding pre-operative fasting, with 44% allowing patients to eat and drink freely until their operation. In those hospitals where a fast was imposed, the most common fasting periods were 6 h for food and 2 h for fluids. Twenty-six per cent of respondents would be prepared to give intravenous sedation to a non-fasted patient during eye surgery: small doses of benzodiazepine were the most frequently suggested method. National evidence-based guidelines for ophthalmic regional anaesthesia are needed.

    A complete history is essential for determining whether the underlying etiology of transient vision loss is from an ischemic or a nonischemic condition that originates in the eye or elsewhere. Ischemic transient vision loss constitutes a transient ischemic attack and requires a full work-up for ischemic stroke. If carotid artery stenosis is found, early intervention may improve the clinical outcome. This article highlights the diagnostic considerations in the evaluation of patients with transient vision loss. PMID:27039494

    Aim of Study: To evaluate the ability of ancillary health staff to use a novel smartphone imaging adapter system (EyeGo, now known as Paxos Scope) to capture images of sufficient quality to exclude emergent eye findings. Secondary aims were to assess user and patient experiences during image acquisition, interuser reproducibility, and subjective image quality. Materials and Methods: The system captures images using a macro lens and an indirect ophthalmoscopy lens coupled with an iPhone 5S. We conducted a prospective cohort study of 229 consecutive patients presenting to L. V. Prasad Eye Institute, Hyderabad, India. Primary outcome measure was mean photographic quality (FOTO-ED study 1–5 scale, 5 best). 210 patients and eight users completed surveys assessing comfort and ease of use. For 46 patients, two users imaged the same patient's eyes sequentially. For 182 patients, photos taken with the EyeGo system were compared to images taken by existing clinic cameras: a BX 900 slit-lamp with a Canon EOS 40D Digital Camera and an FF 450 plus Fundus Camera with VISUPAC™ Digital Imaging System. Images were graded post hoc by a reviewer blinded to diagnosis. Results: Nine users acquired 719 useable images and 253 videos of 229 patients. Mean image quality was ≥ 4.0/5.0 (able to exclude subtle findings) for all users. 8/8 users and 189/210 patients surveyed were comfortable with the EyeGo device on a 5-point Likert scale. For 21 patients imaged with the anterior adapter by two users, a weighted κ of 0.597 (95% confidence interval: 0.389–0.806) indicated moderate reproducibility. High level of agreement between EyeGo and existing clinic cameras (92.6% anterior, 84.4% posterior) was found. Conclusion: The novel, ophthalmic imaging system is easily learned by ancillary eye care providers, well tolerated by patients, and captures high-quality images of eye findings. PMID:27146928

    Peripheral refraction, the refractive error present outside the main direction of gaze, has lately attracted interest due to its alleged relationship with the progression of myopia. The ray tracing procedures involved in its calculation need to follow an approach different from those used in conventional ophthalmic lens design, where refractive errors are compensated only in the main direction of gaze. We present a methodology for the evaluation of the peripheral refractive error in ophthalmic lenses, adapting the conventional generalized ray tracing approach to the requirements of the evaluation of peripheral refraction. The nodal point of the eye and a retinal conjugate surface will be used to evaluate the three-dimensional distribution of refractive error around the fovea. The proposed approach enables us to calculate the three-dimensional peripheral refraction induced by any ophthalmic lens at any direction of gaze and to personalize the lens design to the requirements of the user. The complete evaluation process for a given user prescribed with a -5.76D ophthalmic lens for foveal vision is detailed, and comparative results obtained when the geometry of the lens is modified and when the central refractive error is over- or undercorrected. The methodology is also applied for an emmetropic eye to show its application for refractive errors other than myopia.

    Optical coherence tomography (OCT) has transformed diagnostic ophthalmic imaging but until recently has been limited to the clinic setting. The development of spectral-domain OCT (SD-OCT), with its improved speed and resolution, along with the development of a handheld OCT scanner, enabled portable imaging of patients unable to sit in a conventional tabletop scanner. This handheld SD-OCT unit has proven useful in examinations under anesthesia and, more recently, in intraoperative imaging of preoperative and postoperative manipulations. Recently, several groups have pioneered the development of novel OCT modalities, such as microscope-mounted OCT systems. Although still immature, the development of these systems is directed toward real-time imaging of surgical maneuvers in the intraoperative setting. This article reviews intraoperative imaging of the posterior and anterior segment using the handheld SD-OCT and recent advances toward real-time microscope-mounted intrasurgical imaging.

    Aspirin is the most commonly used antiplatelet drug for prevention of ischaemic stroke. In order to determine the prevalence and nature of aspirin failure, we studied 51 adults admitted with suspected ischaemic stroke and already prescribed daily aspirin. Within 48 hours (h) of onset, blood and urine samples were collected to assess platelet aggregation, activation and aspirin response by a range of methods. All tests were then repeated on a second sample taken 24 h after witnessed administration of 75 mg or 150 mg aspirin. At entry to the study, incomplete response to aspirin, measured by arachidonic acid (AA)-stimulated platelet aggregation, was found in 43% of patients. Following in-hospital aspirin administration, there was a significant decrease in AA-aggregation (p=0.001) suggesting poor adherence to therapy prior to admission. However, residual aggregation (10-15%) persisted in 11 subjects - suggesting alternative causes. In incomplete responders on admission, platelet aggregation with adenosine diphosphate (ADP) was significantly higher compared with responders (p<0.05) but there were no significant differences in collagen aggregation, platelet fibrinogen binding or P-selectin expression, plasma von Willebrand factor, fibrinogen, high-sensitivity C-reactive protein, or the urinary metabolite, 11-dehydro-TxB2. Incomplete platelet inhibition is common around the time of acute cerebrovascular ischaemic events in patients prescribed aspirin. Up to 50% of these observations appear due to incomplete adherence to aspirin therapy. Intervention studies are required to determine the clinical relevance of measured platelet response to aspirin in terms of outcome, and the effectiveness of improved pharmacotherapy for stroke prevention.

    In the present study, novel environmentally responsive ophthalmic drug delivery system composed of two gelling polymers with different phase transition mechanisms was developed in order to obtain sustained drug release in ocular cavity. Combination of polyacrylic acid (carbopol 934P) and xanthan gum was investigated as ophthalmic vehicle and assessed for its in vitro and in vivo performance. Different ratios of these polymers were used to prepare environmentally responsive ophthalmic drug delivery system by simple mixing procedure. Developed formulation was assessed for physical tests such as appearance/clarity, pH, gelation; and performance characteristics such as drug content, rheological measurement, in vitro release, antimicrobial efficiency, in vivo studies for eye irritation, residence time estimation. Prepared formulation showed agreeable appearance/clarity, acceptable pH and good gelation property. In vitro and in vivo studies demonstrated adequate drug content, desired rheological behavior and reasonable in vitro and in vivo drug release property. In conclusion, the optimum concentration of polymers results in increased residence time and sustained drug release. On the basis of these findings, environmentally responsive system based on combination of carbopol and xanthan gum may be considered as a promising tool for ophthalmic delivery. PMID:22200332

    Gastrointestinal cryptococcosis is extremely rare with only a few case reports found in the literature and involvement primarily identified post-mortem. This is a case of 54-year-old man with a 20-year history of poorly controlled human immunodeficiency virus presented with constitutional symptoms along with melena. Diagnostic work up with esophagogastroduodenoscopy showed 4 irregular ulcers in the stomach notable for red-pigmented lesions within the ulcers, erythematous mucosa in the antrum and patchy friable mucosa in the duodenum. H&E staining and Mucicarmine staining showed findings consistent with C. neoformans. Blood culture and cerebrospinal fluid studies also revealed C. neoformans. Cryptococcus neoformans is an AIDS defining illness that most commonly presents as meningoencephalitis and pneumonitis. Key management principles includes: induction of antifungal therapy followed by consolidation and maintenance; management of elevated intracranial pressure and immune reconstitution inflammatory syndrome. Although the organism can infect nearly all organs, gastrointestinal involvement is rarely described. Our case highlights the fact that gastrointestinal C. neoformans infection can be associated with upper gastrointestinal symptoms and may be the initial presentation of disseminated cryptococcosis.

    Urticaria pigmentosa (UP) is the most frequent clinical feature of cutaneous mastocytosis. It usually begins in a bimodal way: a peak of incidence from birth to the age of 3 and the other one between 2(nd) and 6(th) decades of life. Darier's sign is constant over the affected skin without affecting the surrounding skin. When UP starts early, it has a good prognosis disappearing into adolescence, while late onset is often associated with persistent or systemic involvement. This article reports two cases of UP, one with the classic description of the disease and the other with an unusual clinical presentation, prompting the pediatrician to incorporate both forms as different manifestations of the same entity.

    Background Pre-eclampsia (PE) poses a serious challenge to maternal and fetal health in Africa. It is associated with hemodynamic changes that may affect the internal carotid/ophthalmic artery circulation with consequent neuro-ophthalmic manifestations. Ophthalmic artery Doppler (OAD) ultrasound is an important tool that can be used to detect hemodynamic changes in PE and monitor its severity. In this study, we evaluated hemodynamic changes on OAD ultrasound in the ophthalmic arteries of pre-eclamptic women and compared these with values in healthy pregnant women. Methods OAD parameters, such as, peak systolic velocity, peak diastolic velocity, end diastolic velocity, pulsatility index, and peak ratio, were measured on transorbital triplex ultrasound scan with a 7–10 MHz multifrequency linear transducer in 42 consenting pre-eclamptic patients and 41 pregnant controls matched for maternal age, gestational age, and parity at the Department of Radiology, University College Hospital, Ibadan. Univariate, bivariate, and receiver operating characteristic curve data analyses were performed. P<0.05 was considered to be statistically significant. Results Mean resistivity index, pulsatility index, and peak systolic velocity were significantly lower in pre-eclamptic patients than in the controls. Mean peak diastolic velocity, end diastolic velocity, and peak ratio were significantly higher in the pre-eclamptic group. The receiver operating characteristic curve showed that the resistivity index (sensitivity 75%, specificity 77.8%) could distinguish mild from severe PE while the peak ratio (sensitivity 90.5%, specificity 81.3%) could accurately detect PE. Conclusion OAD ultrasound can be used to monitor patients with PE for early detection of progression to severe forms before cerebral complications develop. OAD screening of patients at high risk for PE can also detect early changes of hemodynamic derangement. PMID:26229508

    The search for an ideal intraocular irrigating solution is of paramount importance to te ophthalmic surgeon. An intraocular irrigating solution, as well as surgical technique, can have deleterious effects on ocular tissues. Since an intraocular irrigating solution comes in contact with the cornea, lens, trabecular meshwork, uvea, vitreous, and retina, and ideal irrigant would be ome that ensures biological function for all of these tissues. In a practical sense, the best irrigant is one that causes the least possible damage to the structural integrity and function of the intraocular environment. This paper summarizes the development, uses, and efficacy of intraocular irrigating solutions as currently used during intraocular surgery.

    2012-01-01

    Background Ophthalmic artery chemosurgery (OAC) for retinoblastoma was introduced by us 5 years ago for advanced intraocular retinoblastoma. Because the success was higher than with existing alternatives and systemic side effects limited we have now treated less advanced intraocular retinoblastoma (Reese-Ellsworth (RE) I-III and International Classification Retinoblastoma (ICRB) B and C). Methodology/Principal Findings Retrospective review of 5 year experience in eyes with Reese Ellsworth (Table 1) I (7 eyes), II (6 eyes) or III (6 eyes) and/or International Classification (Table 2) B (19 eyes) and C (11 eyes) treated with OAC (melphalan with or without topotecan) introduced directly into the ophthalmic artery. Patient survival was 100%. Ocular event-free survival was 100% for Reese-Ellsworth Groups I, II and III (and 96% for ICRB B and C) at a median of 16 months follow-up. One ICRB Group C (Reese-Ellsworth Vb) eye could not be treated on the second attempt for technical reasons and was therefore enucleated. No patient required a port and only one patient required transfusion of blood products. The electroretinogram (ERG) was unchanged or improved in 14/19 eyes. Conclusions/Significance Ophthalmic artery chemosurgery for retinoblastoma that was Reese-Ellsworth I, II and III (or International Classification B or C) was associated with high success (100% of treatable eyes were retained) and limited toxicity with results that equal or exceed conventional therapy with less toxicity.

    Various strategies for ocular drug delivery are considered; from basic formulation techniques for improving availability of drugs; viscosity enhancers and mucoadhesives aid drug retention and penetration enhancers promote drug transport into the eye. The use of drug-loaded contact lenses and ocular inserts allows drugs to be better placed where they are needed for more direct delivery. Developments in ocular implants gives a means to overcome the physical barriers that traditionally prevented effective treatment. Implant technologies are under development allowing long-term drug delivery from a single procedure, these devices allow posterior chamber diseases to be effectively treated. Future developments could bring artificial corneas to eliminate the need for donor tissue and one-off implantable drug depots lasting the patient's lifetime.

    1999-06-01

    The absence of verbal feedback, available from most human patients, is a major limitation in veterinary diagnosis in general and in the evaluation of ophthalmic lens opacity in particular. A novel compact dynamic light scattering (DLS) instrument, developed at NASA, offers significant mitigation to this limitation. It not only yields objective repeatable non-invasive estimation of lens opacity but also provides insight into the nature of chemical and physical alternations in the lens and other eye structures. For example, DLS measurements of the cataractous lens may be interpreted in terms of alpha crystalline protein size. In contrast to most conventional methods, the examination results are numerical and readily accommodate statistical analysis. We present results of DLS measurements in laboratory rabbits with naphthalene induced cataracts, rodents with genetically conditioned hypertension and/or diabetes mellitus; as well as applications of the DLS method in clinical veterinary patients. Use of DLS in examination of phacoemulsification fluid, urine and other biological materials, and potential applications in ocular toxically will also be discussed.

  19. The management of ophthalmic involvement in blue rubber bleb nevus syndrome

    PubMed Central

    Petek, Bradley; Jones, Robin L.

    2014-01-01

    Objective: Blue rubber bleb nevus syndrome is a rare vascular disease most commonly associated with venous malformations of the skin and the gastrointestinal tract. Few ophthalmic cases have been reported to date, and no clear treatment regimen exists. We describe the case of a 59-year-old man, along with a review of literature, to help in the future diagnosis and treatment of patients with the disease. Methods: This paper is an observational case report and a review of medical literature on the syndrome from 1981 to present. Results: Our patient developed a dural arteriovenous fistula in his orbit after being diagnosed with a familial form of blue rubber bleb nevus syndrome. Multiple endovascular embolization procedures eliminated all of his ocular symptoms. Surgical procedures were also successful in other cases reviewed, and similar symptoms were seen across cases. Conclusions: Comparing our case with other ophthalamic reports in literature, surgical intervention appears to be a plausible long-term treatment for optic manifestations of blue rubber bleb nevus syndrome. Systemic therapies, including sirolimus and corticosteroids, have had limited success in the long-term treatment of other forms of blue rubber bleb nevus syndrome, and therefore are not recommended in the treatment of ocular symptoms.

    Recent improvements in technology have enabled integration of SD-OCT into the optical path of an operating microscope. Here we present an overview of possible applications of iOCT (intraoperative optical coherence tomography) for retinal, glaucoma and corneal surgery. iOCT-based imaging can not only improve safety and quality of the surgery but also the learning curve of the surgeon. The ability to visualize barely visible or transparent structures with iOCT has achieved a significant added value intraoperatively, particularly in macular surgery, trabeculectomy and lamellar keratoplasty. Further, systematic assessment is warranted to define the usefulness of the iOCT more precisely. PMID:27126797

    2014-06-01

    Pixelated liquid crystal displays have been widely used as spatial light modulators to implement programmable diffractive optical elements, particularly diffractive lenses. Many different applications of such components have been developed in information optics and optical processors that take advantage of their properties of great flexibility, easy and fast refreshment, and multiplexing capability in comparison with equivalent conventional refractive lenses. We explore the application of programmable diffractive lenses displayed on the pixelated screen of a liquid crystal on silicon spatial light modulator to ophthalmic optics. In particular, we consider the use of programmable diffractive lenses for the visual compensation of refractive errors (myopia, hypermetropia, astigmatism) and presbyopia. The principles of compensation are described and sketched using geometrical optics and paraxial ray tracing. For the proof of concept, a series of experiments with artificial eye in optical bench are conducted. We analyze the compensation precision in terms of optical power and compare the results with those obtained by means of conventional ophthalmic lenses. Practical considerations oriented to feasible applications are provided.

  5. Microscope-integrated intraoperative OCT with electrically tunable focus and heads-up display for imaging of ophthalmic surgical maneuvers

    2014-01-01

    We present novel optical and mechanical designs for a microscope-integrated intraoperative optical coherence tomography (iOCT) system with enhanced function and ergonomics for visualization of ophthalmic surgical maneuvers. Integration of an electrically tunable lens allows rapid focal plane adjustment and iOCT imaging of both anterior and posterior segment tissue microstructures while maintaining parfocality with the ophthalmic surgical microscope. We demonstrate novel visualization of instrument positions relative to tissue layers of interest as colormap overlays onto en face OCT data, which may provide integrative display of volumetric information during surgical maneuvers. Finally, we implement a heads-up display system to provide real-time feedback as proof-of-principle for iOCT-guided ophthalmic surgery. PMID:24940546

    We present the case of a 60-year-old man with persistent epistaxis for 20 days that had started 2 weeks after removal of a nasogastric tube placed for an abdominal operation. There was no pathologic finding at selective facial and internal maxillary artery injections. An injury to the ethmoidal branches of the ophthalmic arteries or other arterial origins of bleeding was suspected. The internal carotid artery angiography revealed a pseudoaneurysm of an anterior ethmoidal branch of the left ophthalmic artery. The pseudoaneurysm was occluded with NBCA-histoacryl (25%) injection.

    This case illustrates that hematologic disorders must be considered as a potentially life-threatening cause for vision loss. Proper laboratory workup and timely interdisciplinary approach are essential to ensure the best possible care for ophthalmic patients. Historically, before the use of bone marrow biopsy, the ophthalmologist was often asked to assist in the diagnosis of leukemia. Since ophthalmological symptoms may be the initial presenting signs of leukemia as highlighted in this case, the ophthalmogist is still of crucial importance. PMID:27721787

    Biorepositories are collections of surgically obtained human tissues for current and future investigations of disease mechanisms, therapeutics, and diagnostics. In ophthalmology, a critical challenge is how to interface the operating room with the laboratory. To attain standards required for basic research, clinical and research teams must cooperate to collect, annotate, and store specimens that yield consistent results required for advanced molecular techniques. We developed an efficient platform for obtaining vitreous and other eye tissues from the operating room and transferring them to the lab. The platform includes a mobile lab cart for on-site tissue processing, a multi-user, web-based database for point-of-care phenotypic capture, and an integrated data tracking system for long-term storage. These biorepository instruments have proven essential for our studies in ophthalmic disease proteomics. This system can be implemented in other operating rooms and laboratories for a variety of biological tissues. PMID:24115637

  10. A polycarbonate ophthalmic-prescription lens series.

    PubMed

    Davis, J K

    1978-08-01

    Improvements in polycarbonate material, production techniques, and scratch-resistant coatings, combined with a process-oriented design, have resulted in a precision lens series. Surface quality is comparable to that of untreated glass ophthalmic lenses. The repeatability of the process results in closely controlled axial power and off-axis performance. For most lens prescriptions, the ANSI Z80.1 optical-center specifications for prescription accuracy are maintained through a total field of view of 40 deg for an 8-mm range of center-of-rotation distances. Off-axis astigmatism is controlled for near-point seeing. The lenses are both lighter and thinner than those of crown glass. A scratch-resistant coating reduces the reflections normally associated with high-index (1.586) materials. Impact resistance exceeds that required by ANSI Z80.7 and is many times that required by ANSI Z80.1.

    To investigate ophthalmic changes in spaceflight, we would like to predict the impact of blood dysregulation and elevated intracranial pressure (ICP) on Intraocular Pressure (IOP). Unlike other physiological systems, there are very few lumped parameter models of the eye. The eye model described here is novel in its inclusion of the human choroid and retrobulbar subarachnoid space (rSAS), which are key elements in investigating the impact of increased ICP and ocular blood volume. Some ingenuity was required in modeling the blood and rSAS compartments due to the lack of quantitative data on essential hydrodynamic quantities, such as net choroidal volume and blood flowrate, inlet and exit pressures, and material properties, such as compliances between compartments.

    Two studies were carried out in volunteers without any abnormal ocular conditions to assess the effects and safety of an ophthalmic preparation of oxymetazoline (0.025%). In the first study in which oxymetazoline was compared with placebo and phenylephrine, the results of infra-red electronic pupillography showed that oxymetazoline in therapeutic doses had no effect on pupil size or near point recession. The second study, which was a double-blind forced choice comparison of two different formulations against placebo and 1% naphazoline, showed from assessments of the degree of ocular discomfort and hyperaemia that oxymetazoline was well tolerated and the subjects preferred oxymetazoline in a boric acid rather than in a phosphate solution.

  13. An historical ophthalmic study of Jane Austen.

    Today, no other classic novelist has the popularity or power of Jane Austen, and in 2013 the world will celebrate 200 years of her comic masterpiece Pride and Prejudice. Her millions of fans have an abiding fascination with all aspects of her life, including her health and the cause of her death. This historical ophthalmic study of Jane Austen, based on very incomplete medical bibliographic data, finds that she had a mild ocular surface disorder from age 23. This disorder did not significantly impact on her visual performance for writing. There are many references to eyes in her novels, but Jane's eyes and those of her characters cannot contribute further to the debate around the cause of her death at age 41.

    The aim of this study is to describe the effect of transarterial embolization from the ophthalmic artery as a pretreatment for orbital exenteration. A 75-year-old Chinese man with a 7-year history of gradual increase of the left eye swelling showed a massive conjunctival tumor growing outwardly from the interpalpebral fissure and had no light perception in the left eye. Magnetic resonance imaging showed orbital invasion of the tumor around the left eyeglobe. The initial surgery for the planned orbital exenteration was discontinued after skin incision around the orbital margin due to massive hemorrhage. The patient underwent transarterial embolization with gelatin sponge (Spongel) of the feeding arteries from the left ophthalmic artery and, the next day, had orbital exenteration with well-controllable bleeding and reconstruction with free vascularized anterolateral thigh cutaneous flap transfer. Pathologically, well-differentiated squamous cell carcinoma proliferated in exophytic, papillary, and nested fashions, arising from the bulbar conjunctiva. Tumor cells were also found in the conjunctival stroma around the vessels. The sclera at the equator had a perforated site with tumor cell invasion, but no intraocular invasion was found. Hematoxylin-positive gelatin sponges were found inside the orbital vessels and large choroidal vessels. In conclusion, transarterial embolization of feeding arteries arising from the ophthalmic artery is a useful pretreatment to control bleeding at orbital exenteration for malignancy.

    Purpose Randomised controlled trials (RCTs) represent a gold standard for evaluating therapeutic interventions. However, poor reporting clarity can prevent readers from assessing potential bias that can arise from a lack of methodological rigour. The Consolidated Standards of Reporting Trials statement for non-pharmacological interventions 2008 (CONSORT NPT) was developed to aid reporting. RCTs in ophthalmic surgery pose particular challenges in study design and implementation. We aim to provide the first assessment of the compliance of RCTs in ophthalmic surgery to the CONSORT NPT statement. Method In August 2012, the Medline database was searched for RCTs in ophthalmic surgery reported between 1 January 2011 and 31 December 2011. Results were searched by two authors and relevant papers selected. Papers were scored against the 23-item CONSORT NPT checklist and compared against surrogate markers of paper quality. The CONSORT score was also compared between different RCT designs. Results In all, 186 papers were retrieved. Sixty-five RCTs, involving 5803 patients, met the inclusion criteria. The mean CONSORT score was 8.9 out of 23 (39%, range 3.0–14.7, SD 2.49). The least reported items related to the title and abstract (1.6%), reporting intervention adherence (3.1%), and interpretation of results (4.7%). No significant correlation was found between CONSORT score and journal impact factor (R=0.14, P=0.29), number of authors (R=0.01, P=0.93), or whether the RCT used paired-eye, one-eye, or two-eye designs in their randomisation (P=0.97). Conclusions The reporting of RCTs in ophthalmic surgery is suboptimal. Further work is needed by trial groups, funding agencies, authors, and journals to improve reporting clarity. PMID:25214001

    Aim To assess the frequency of contamination of ophthalmic solutions in a long‐term care facility and to describe the characteristics of contaminated solutions. Methods One hundred and twenty‐three ophthalmic solutions used for patient treatment in a long‐term care facility were cultured for bacteria. The culture results were analysed according to the therapeutic class of the solution, how long the bottle had been in use and the appearance of the bottle on visual inspection. Results 10 (8%) of the 123 multiple‐dose solutions were contaminated with bacteria: 4 (50%) of 8 steroid‐containing anti‐inflammatory solutions, 2 (33%) of 6 combination antimicrobial and steroid‐containing anti‐inflammatory solutions, 2 (6%) of 34 solutions for treatment of glaucoma, and 2 (4%) of 57 medications for “dry eye”. None of the mydriatic, miotic or non‐combination antimicrobial solutions was contaminated. Proteus mirabilis was identified in 8 (80%) of the 10 contaminated solutions. Only 30% of the contaminated solution bottles were classified as “dirty” bottles when the bottles were visually inspected. Neither the length of time the solutions had been in use nor the appearance of the bottle predicted contamination. Conclusions 8% of ophthalmic solutions used in a long‐term care facility were contaminated with bacteria, most frequently Proteus mirabilis. Compared with solutions not containing steroids, steroid solutions were 5.8 times more likely to be contaminated (RR = 5.84, 95% CI: 2.42 to 14.10, p<0.002). The frequent contamination during reuse of certain steroid‐containing ophthalmic solutions raises the question of whether single‐use solutions might be preferred for these and other classes of ocular drugs.

    We performed duplex and transcranial Doppler studies in 36 patients with angiographically documented internal carotid artery occlusion (ICAO) to determine the effect of ophthalmic artery collateral (OAC) on measures of vascular resistivity both proximal and distal to the occlusion. Resistance in the common carotid artery, measured by the resistivity index, was significantly lower in the group with OAC than in those without OAC, indicating a shunt to the low resistance intracranial circuit. The pulsatility index (PI) of the Doppler signal in the ipsilateral middle cerebral artery, a measure of both inflow pressure and distal vascular resistance, did not differ between those with and without OAC. However, the presence of circle of Willis collateral pathways (anterior communicating and/or posterior communicating artery) did appear to have a significant effect on pulsatility. When both were present angiographically, PI was higher than in the group with only 1 Willisian collateral. These findings suggest that OAC has a marginal effect on vascular resistance in arterial bed distal to an ICAO, while Willisian collaterals appear to have a more important role in cerebral perfusion, as measured indirectly by Doppler methods.

    Purpose: To investigate the penetration of 0.3% gatifloxacin ophthalmic gel, 0.3% gatifloxacin ophthalmic solution and 0.5% levofloxacin ophthalmic solution into aqueous humor after topical application. Materials and Methods: Age-related cataract patients (150 eyes in 150 cases) receiving phacoemulsification were randomly divided into three groups: a 0.3% gatifloxacin gel group (n=50), a 0.3% gatifloxacin solution group (n=50), and a 0.5% levofloxacin solution group (n=50). Each group was administered one drop of gel or solution every 15 minutes for four doses. Aqueous samples were collected at different time points after the last drop. High pressure liquid chromatography (HPLC) was applied to determine the concentrations. The one-way ANOVA analysis was performed. Results: Our data indicated that the concentration of the gatifloxacin gel group was higher than that of the gatifloxacin solution group at all time points (P <0.05); moreover, the gatifloxacin gel group exhibited higher levels than the levofloxacin solution group at 120.0 min and 180.0 min (P<0.05). Furthermore, the gatifloxacin gel produced the highest concentration at 120.0 min, and the gatifloxacin and levofloxacin solutions reached their peak values at 60.0 min. Conclusions: 0.3% gatifloxacin ophthalmic gel application produced highest aqueous humor drug concentration, maintained the longest time, had the best penetration and bioavailability. PMID:26078713

    The present paper is focused on the study of the auditory function and cerebral circulation estimated based on the results of rheoencephalographc examination of 75 patients presenting with disordered sound perception and divided into two groups. Group 1 was comprised of the patients complaining of impaired hearing of the tones only within the extended frequency range (9-16 kHz), group 2 consisted of the patients suffering impaired hearing in the conventional frequency range (0.125-8 kHz). It was shown that the brainstem structures of the auditory analyzer in the patients of both groups remained unaffected whereas the cortical structures thereof in the patients of group 2 exhibited the signs of dysfunction. Cerebral circulation was disturbed in both groups, but its changes were especially well pronounced in the patients of group 2. These findings are of interest in the context of diagnostics and treatment of the patients presenting with early disorders of the sound perception function.

    Ophthalmic surgeons manipulate micron-scale tissues using stereopsis through an operating microscope and instrument shadowing for depth perception. While ophthalmic microsurgery has benefitted from rapid advances in instrumentation and techniques, the basic principles of the stereo operating microscope have not changed since the 1930's. Optical Coherence Tomography (OCT) has revolutionized ophthalmic imaging and is now the gold standard for preoperative and postoperative evaluation of most retinal and many corneal procedures. We and others have developed initial microscope-integrated OCT (MIOCT) systems for concurrent OCT and operating microscope imaging, but these are limited to 2D real-time imaging and require offline post-processing for 3D rendering and visualization. Our previously presented 4D MIOCT system can record and display the 3D surgical field stereoscopically through the microscope oculars using a dual-channel heads-up display (HUD) at up to 10 micron-scale volumes per second. In this work, we show that 4D MIOCT guidance improves the accuracy of depth-based microsurgical maneuvers (with statistical significance) in mock surgery trials in a wet lab environment. Additionally, 4D MIOCT was successfully performed in 38/45 (84%) posterior and 14/14 (100%) anterior eye human surgeries, and revealed previously unrecognized lesions that were invisible through the operating microscope. These lesions, such as residual and potentially damaging retinal deformation during pathologic membrane peeling, were visualized in real-time by the surgeon. Our integrated system provides an enhanced 4D surgical visualization platform that can improve current ophthalmic surgical practice and may help develop and refine future microsurgical techniques.

    In this paper, we present a 1050 nm electrically-pumped micro-electro-mechanically-tunable vertical-cavity-surface-emitting-laser (MEMS-VCSEL) with a record dynamic tuning bandwidth of 63.8 nm, suitable for swept source optical coherence tomography (SS-OCT) imaging. These devices provide reduced cost & complexity relative to previously demonstrated optically pumped devices by obviating the need for a pump laser and associated hardware. We demonstrate ophthalmic SS-OCT imaging with the electrically-pumped MEMS-VCSEL at a 400 kHz axial scan rate for wide field imaging of the in vivo human retina over a 12 mm × 12 mm field and for OCT angiography of the macula over 6 mm × 6 mm & 3 mm × 3 mm fields to show retinal vasculature and capillary structure near the fovea. These results demonstrate the feasibility of electrically pumped MEMS-VCSELs in ophthalmic instrumentation, the largest clinical application of OCT. In addition, we estimate that the 3 dB coherence length in air is 225 meters ± 51 meters, far greater than required for ophthalmic SS-OCT and suggestive of other distance ranging applications.

    Owing to its unique anatomical and physiological functions, ocular surface presents special challenges for both design and performance evaluation of the ophthalmic ointment drug products formulated with a variety of bases. The current investigation was carried out to understand and identify the appropriate in vitro methods suitable for quality and performance evaluation of ophthalmic ointment, and to study the effect of formulation and process variables on its critical quality attributes (CQA). The evaluated critical formulation variables include API initial size, drug percentage, and mineral oil percentage while the critical process parameters include mixing rate, temperature, time and cooling rate. The investigated quality and performance attributes include drug assay, content uniformity, API particle size in ointment, rheological characteristics, in vitro drug release and in vitro transcorneal drug permeation. Using design of experiments (DoE) as well as a novel principle component analysis approach, five of the quality and performance attributes (API particle size, storage modulus of ointment, high shear viscosity of ointment, in vitro drug release constant and in vitro transcorneal drug permeation rate constant) were found to be highly influenced by the formulation, in particular the strength of API, and to a lesser degree by processing variables. Correlating the ocular physiology with the physicochemical characteristics of acyclovir ophthalmic ointment suggested that in vitro quality metrics could be a valuable predictor of its in vivo performance.

  13. Optimization of sup 125 I ophthalmic plaque brachytherapy

    Episcleral plaques containing {sup 125}I sources are often used in the treatment of ocular melanoma. Within four years post-treatment, however, the majority of patients experience some visual loss due to radiation retinopathy. The high incidence of late complications suggests that careful treatment optimization may lead to improved outcome. The goal of optimization would be to reduce the magnitude of vision-limiting complications without compromising tumor control. We have developed a three-dimensional computer model for ophthalmic plaque therapy which permits us to explore the potential of various optimization strategies. One simple strategy which shows promise is to maximize the ratio of dose to the tumor apex (T) compared to dose to the macula (M). By modifying the parameters of source location, activity distribution, source orientation, and shielding we find that the calculated T:M ratio can be varied by a factor of 2 for a common plaque design and posterior tumor location. Margins and dose to the tumor volume remain essentially unchanged.

  14. [Nutritional management of patients with acute pancreatitis: when the past is present].

    Patients with acute pancreatitis usually present nutritional status impairment. In alcoholic pancreatitis this impairment is usually presented before hospital admission. In patients with long-term complicated pancreatitis, malnutrition develops during the course of the disease. Besides, these patients present an increased stress and protein hypercatabolism. Treatment of acute pancreatitis usually maintains patients in a short period of starvation. In mild pancreatitis, starvation is needed for a few days, beginning progressively oral feeding. These patients don't need special nutritional support, unless they were previously malnourished. Patients with severe acute pancreatitis should always receive artificial nutritional support in order to preserve the nutritional status as starvation will be maintained for more than one week. In this paper, we review the nutritional treatment in these situations, trying to answer some different questions: type of nutritional support, when it should be started and when it is indicated to withdraw.

    Although cryptococcal meningitis (CM) typically occurs in immunocompromised hosts, immunocompetent humans are susceptible to CM. In humans with an intact immune system, CM presents with signs and symptoms typical of meningitis, including fever, headache and neck stiffness. The present study reported the case of a female immunocompetent patient who presented visual blurring in both eyes and bilateral papilledema for ~1 month. Following hospital admission, the patient was diagnosed with optic nerve inflammation and was treated with intravenous methylprednisolone and oral prednisone. However, the initial symptoms failed to improve and the patient developed a headache. The microscopic examination and India ink test performed using the cerebrospinal fluid of the patient showed the presence of Cryptococcus neoformans. Following combined treatment with amphotericin B and fluconazole, the patient made a full recovery with total resolution of the initial symptoms. This case demonstrates that CM in immunocompetent patients may initially include eye symptoms, which may result in a delayed diagnosis of CM. PMID:27446330

    Background To review the visual status and clinical presentation of patients with retinitis pigmentosa (RP). Methodology Multicenter, retrospective, and analytical review was conducted of the visual status and clinical characteristics of patients with RP at first presentation from January 2007 to December 2011. Main outcome measure was the World Health Organization’s visual status classification in relation to sex and age at presentation. Data analysis by SPSS (version 15) and statistical significance was assumed at P<0.05. Results One hundred and ninety-two eyes of 96 patients with mean age of 39.08±18.5 years and mode of 25 years constituted the study population; 55 (57.3%) were males and 41 (42.7%) females. Loss of vision 67 (69.8%) and night blindness 56 (58.3%) were the leading symptoms. Twenty-one (21.9%) patients had a positive family history, with RP present in their siblings 15 (71.4%), grandparents 11 (52.3%), and parents 4 (19.4%). Forty (41.7%) were blind at presentation and 23 (24%) were visually impaired. Blindness in six (15%) patients was secondary to glaucoma. Retinal vascular narrowing and retinal pigmentary changes of varying severity were present in all patients. Thirty-five (36.5%) had maculopathy, 36 (37.5%) refractive error, 19 (20%) lenticular opacities, and eleven (11.5%) had glaucoma. RP was typical in 85 patients (88.5%). Older patients had higher rates of blindness at presentation (P=0.005); blindness and visual impairment rate at presentation were higher in males than females (P=0.029). Conclusion Clinical presentation with advanced diseases, higher blindness rate in older patients, sex-related difference in blindness/visual impairment rates, as well as high glaucoma blindness in RP patients requires urgent attention in southwestern Nigeria.

    Isolated adrenocorticotropic hormone (ACTH) deficiency (IAD) is a potentially fatal condition that is difficult to diagnose. The authors diagnosed IAD in a patient who presented with recurrent oesophageal ulceration resulting in oesophageal stenosis. The recurrent oesophageal ulcers were due to frequent nausea and vomiting that were the presenting digestive symptoms of adrenal insufficiency. Severe hypoglycaemia during this patient's course suggested the diagnosis of adrenal insufficiency. This case is educational because digestive symptoms are the most common symptoms in patients with adrenal insufficiency, but the diagnosis of adrenal insufficiency in such patients is not easy.

    The incidence of superior vena cava (SVC) obstruction associated with non-malignant diseases is on the rise, and a large percentage of these patients are on hemodialysis (HD). The objective was to characterize the presentation, symptoms and outcomes of HD patients with SVC obstruction identified on computerized tomography (CT) compared to patients with other etiologies such as neoplasm. A search was performed through the PACS system using key words to identify patients with SVC obstruction. The CT scans and charts were reviewed for degree of obstruction, signs, symptoms and outcomes. Thirty-six patients were included in the study. Thirteen were on HD and of these, five had symptoms associated with SVC obstruction and one had concordant findings on physical exam. In comparison, thirteen patients with a chest neoplasm had symptoms and four had concordant findings on physical exam. On follow up, 31% of the HD patients died and of these 60% were symptomatic and died within 2 years. 29% of lung cancer patients died within 16 months. The majority of the HD patients had complete SVC obstruction (85%) as opposed to those with a chest neoplasm who mostly had partial SVC occlusion (67%). In conclusion, patients on HD with SVC obstruction are less often symptomatic than those with a neoplasm. However, these HD patients had a death rate similar to the patients with cancer. This risk seems to increase in those who are symptomatic. Diagnosis of SVC obstruction by CT in HD patients may help identify those with less favorable prognosis.

    An ophthalmic virtual environment has been developed as part of a teleoperated microsurgical robot built to perform surgery on the eye. The virtual environment is unique in that it incorporates a detailed continuum model of the anatomical structures of the eye, its mechanics and optical properties, together with a less detailed geometric-mechanical model of the face. In addition to providing a realistic visual display of the eye being operated on, the virtual environment simulates tissue properties during manipulation and cutting and the forces involved are determined by solving a mechanical finite element model of the tissue. These forces are then fed back to the operator via a force reflecting master and so the surgeon can experience both the visual and mechanical sensations associated with performing surgery. The virtual environment can be used to enhance the images produced by the camera on the microsurgical slave robot during surgery and as a surgical simulator in which it replaces these images with computer graphics generated from the eye model.

    In this work, we designed and realized a new phantom able to mimic the principal mechanical, rheological, and physical cues of the human eye and that can be used as a common benchmark to validate new surgical procedures, innovative vitrectomes, and as a training system for surgeons. This phantom, in particular its synthetic humor vitreous, had the aim of reproducing diffusion properties of the natural eye and can be used as a system to evaluate the pharmacokinetics of drugs and optimization of their dose, limiting animal experiments. The eye phantom was built layer-by-layer starting from the sclera up to the retina, using low cost and easy to process polymers. The validation of the phantom was carried out by mechanical characterization of each layer, by diffusion test with commercial drugs into a purposely developed apparatus, and finally by a team of ophthalmic surgeons. Experiments demonstrated that polycaprolactone, polydimethylsiloxane, and gelatin, properly prepared, are the best materials to mimic the mechanical properties of sclera, choroid, and retina, respectively. A polyvinyl alcohol-gelatin polymeric system is the best for mimicking the viscosity of the human humor vitreous, even if the bevacizumab half-life is lower than in the human eye.

    Simulating mobility tasks in a virtual environment reduces risk for research subjects, and allows for improved experimental control and measurement. We are currently using a simulated shopping mall environment (where subjects walk on a treadmill in front of a large projected video display) to evaluate a number of ophthalmic devices developed at the Schepens Eye Research Institute for people with vision impairment, particularly visual field defects. We have conducted experiments to study subject's perception of "safe passing distance" when walking towards stationary obstacles. The subject's binary responses about potential collisions are analyzed by fitting a psychometric function, which gives an estimate of the subject's perceived safe passing distance, and the variability of subject responses. The system also enables simulations of visual field defects using head and eye tracking, enabling better understanding of the impact of visual field loss. Technical infrastructure for our simulated walking environment includes a custom eye and head tracking system, a gait feedback system to adjust treadmill speed, and a handheld 3-D pointing device. Images are generated by a graphics workstation, which contains a model with photographs of storefronts from an actual shopping mall, where concurrent validation experiments are being conducted.

    A 12-month-old boy with a history of bilateral retinoblastoma refractory to systemic chemotherapy, laser therapy and cryotherapy, with excellent response to previous intra-arterial melphalan infusion, presents with active tumour deposits in the right eye. Repeat intra-arterial chemotherapy was recommended. Previous bilateral melphalan infusion was uneventful using flow-guided catheterisation technique. Direct catheterisation of the right ophthalmic artery was unsuccessful despite employment of several flow-guided and over-the-wire catheters. Superselective catheterisation of the ipsilateral middle meningeal artery was unable to identify an anastomotic connection to the ophthalmic artery; however, angiography of the anterior deep temporal artery identified an alternate route for chemotherapy infusion. The anterior deep temporal artery was successfully and safely catheterised to infuse chemotherapy into the ophthalmic artery. The anterior deep temporal artery is an important potential anastomotic connection to the ophthalmic artery that can be used safely and effectively for central retinal artery chemotherapy infusion for retinoblastoma treatment.

    Cerebral vasculature is often the target of stroke studies. However, the vasculature supplying the eye might also be affected by ischemia. The aim of the present study was to investigate if the transient global cerebral ischemia (GCI) enhances vascular effect of endothelin-1 (ET-1) and 5-hydroxytryptamine/serotonin (5-HT) on the ophthalmic artery in rats, leading to delayed retinal damage. This was preformed using myography on the ophthalmic artery, coupled with immunohistochemistry and electroretinogram (ERG) to assess the ischemic consequences on the retina. Results showed a significant increase of ET-1 mediated vasoconstriction at 48 hours post ischemia. The retina did not exhibit any morphological changes throughout the study. However, we found an increase of GFAP and vimentin expression at 72 hours and 7 days after ischemia, indicating Müller cell mediated gliosis. ERG revealed significantly decreased function at 72 hours, but recovered almost completely after 7 days. In conclusion, we propose that the increased contractile response via ET-1 receptors in the ophthalmic artery after 48 hours may elicit negative retinal consequences due to a second ischemic period. This may exacerbate retinal damage after ischemia as illustrated by the decreased retinal function and Müller cell activation. The ophthalmic artery and ET-1 mediated vasoconstriction may be a valid and novel therapeutic target after longer periods of ischemic insults. PMID:27322388

    Background: Early treatment of ST elevation myocardial infarction (STEMI) is essential to improve survival of these patients. However, not all patients present early enough to receive optimal treatment especially in third world countries. Social factors affecting early vs. late treatment have not been studied, particularly in the Middle East. Thus, the aim of this study was to determine the social factors associated with delayed presentation of STEMI patients. Methods: All patients with STEMI presenting to King Abdulaziz Cardiac Center (KACC) between October 2013 and July 2014 were approached. After obtaining consent, patients were interviewed regarding their psychosocial circumstances using a standardized questionnaire. Their medical charts were also reviewed for further clinical data. Patients were divided according to their symptom-to-door time into early ( ≤ 6h) and late (>6h) presentation and group comparisons were conducted. Results: A total of 79 patients were enrolled, of which 24 patients (30%) presented late. Patients with increased symptom-to-door time had higher prevalence of diabetes (40% vs. 79.2%, p = 0.001), hypertension (43.6% vs. 70.8%, p = 0.023), and dyslipidemia (23.6% vs. 54.2%, p = 0.009). Most of the late presenters did not undergo primary coronary intervention (72.7% vs. 47.8%, P = 0.034) and had less prior information about myocardial infarction (43.6% vs. 25%, P = 0.023). Late presenters were more often illiterates and lived most often far away from the hospital. Using multivariate logistic regression; dyslipidemia was the only independent predictor for the late hospital presentation for STEMI patients. Conclusion: One third of patients with STEMI present more than six hours after symptom onset; these patients have a higher prevalence of coronary risk factors and less information about STEMI. Programs should be designed to educate patients and the general public about the symptoms of STEMI and the necessary action to be

    Ophthalmic complications associated with endoscopic sinus surgery (ESS) are quite rare. There is a paucity of reliable data and limited experience on the clinical findings and treatments of these injuries. Our study here is to characterize the types of orbital injury following ESS, in particular extraocular muscle injury, and to evaluate the long-term therapeutic outcomes as compiled from a relatively large sample of Chinese patients.A series of 27 patients (21 males and 6 females; mean age = 42.6 years, ranges: 10-60 years) were retrospectively reviewed. The mean duration of orbital complication was 6.6 months (ranges: 1 day to 24 months). The right eye was affected in 19 patients and the left in 8 patients. All patients had various extraocular muscle dysfunction, including contusion, oculomotor nerve damage, muscle entrapment, muscle transection, and muscle destruction. All patients subjected to strabismus surgery showed an obvious reduction in deviation. Three patients achieved orthophoria without any surgery during the period of observation. All patients displayed mild to complicated orbital hemorrhage that often disappeared within 2 weeks. Optic nerve injury occurred in 29.6% of patients and vision damage in these patients was often irreversible.All patients with ophthalmic complications after ESS had strabismus and extraocular muscle dysfunction. Timing and type of strabismus surgery performed depended on the severity and number of muscles involved as well as the type of injury. This surgery is less effective in cases of restriction factor adhesion and/or entrapment as compared to that of patients with other types of strabismus. Orbital hemorrhages were usually resolved spontaneously, but optic nerve injury was mostly irreversible. PMID:27661034

    Nasal furunculosis is a deep infection of hair follicle within the nasal vestibule. In this report, the authors presented a 49-year-old woman with 4-day history of focal red area and tender swelling on the tip of her nose. On physical examination, together with a swelling at nasal vestibulum, erythema, and edema on the skin of nasal tip were observed, which is called the Rudolph Sign. The patient was treated with intranasal topical mupirocin and oral sodium fusidate. Because nasal furunculosis may lead to serious complications such as ophthalmic vein thrombosis and cavernous sinus thrombosis, early diagnosis and effective treatment is essential. PMID:26335324

    Purpose. Acute liver failure (ALF) treated with conservative therapy has a poor prognosis, although individual survival varies greatly. In these patients, the eligibility for liver transplantation must be quickly decided. The aim of this study was to assess the role of transjugular liver biopsy (TJLB) in the management of patients with the clinical presentation of ALF. Methods. Seventeen patients with the clinical presentation of ALF were referred to our institution during a 52 month period. A TJLB was performed using the Cook Quick-Core needle biopsy. Clinical data, procedural complications, and histologic findings were evaluated. Results. Causes of ALF were virus hepatitis B infection in 7 patients, drug toxicity in 4, mushroom in 1, Wilson's disease in 1, and unknown origin in 4. TJLB was technically successful in all patients without procedure-related complications. Tissue specimens were satisfactory for diagnosis in all cases. In 14 of 17 patients the initial clinical diagnosis was confirmed by TJLB; in 3 patients the initial diagnosis was altered by the presence of unknown cirrhosis. Seven patients with necrosis <60% were successfully treated with medical therapy; 6 patients with submassive or massive necrosis ({>=}85%) were treated with liver transplantation. Four patients died, 3 had cirrhosis, and 1 had submassive necrosis. There was a strict statistical correlation (r = 0.972, p < 0.0001) between the amount of necrosis at the frozen section examination and the necrosis found at routine histologic examination. The average time for TJLB and frozen section examination was 80 min. Conclusion. In patients with the clinical presentation of ALF, submassive or massive liver necrosis and cirrhosis are predictors of poor prognosis. TLJB using an automated device and frozen section examination can be a quick and effective tool in clinical decision-making, especially in deciding patient selection and the best timing for liver transplantation.

    Background: Although physiologic and pathologic changes associated with microgravity exposure have been studied extensively, the effect of this environment on the eye is largely unknown. Over the last several years, NASA s Space Medicine Division has documented astronauts presenting with varying degrees of disc edema, globe flattening, choroidal folds, cotton wool spots, and hyperopic shifts after long-duration space flight. Methods: Before and after long-duration space flight, six astronauts underwent complete eye examinations to include cycloplegic and/or manifest refraction and fundus photography. Five of these astronauts had Optical Coherence Tomography (OCT) and Magnetic Resonance Imaging (MRI) performed following their missions. Results: Following exposure to space flight of approximately 6-months duration, six astronauts had neuro-ophthalmic findings. These consisted of disc edema in four astronauts, globe flattening in four astronauts, choroidal folds in four astronauts, cotton wool spots in three astronauts, nerve fiber layer thickening by OCT in five astronauts, and decreased near vision in five astronauts. Four of the astronauts with near vision complaints had a hyperopic shift equal to or greater than + 0.50D between pre- and post-mission spherical equivalent refraction in one or both eyes (range +0.50D to +1.50D). These same four had globe flattening by MRI. Conclusions: The findings we describe may have resulted from a rise in intracranial pressure caused by microgravity fluid shifts, and could represent parts of a spectrum of ocular and cerebral responses to extended microgravity.

    In production of ophthalmic freeform optics like progressive eyeglasses, the specimens are tested according to a standardized method which is based on the measurement of the vertex power on usually less than 10 points. For a better quality management and thus to ensure more reliable and valid tests, a more comprehensive measurement approach is required. For Shack Hartmann Sensors (SHS) the dynamic range is defined by the number of micro-lenses and the resolution of the imaging sensor. Here, we present an approach for measuring wavefronts with increased dynamic range and lateral resolution by the use of a scanning procedure. Therefore, the proposed innovative setup is based on galvo mirrors that are capable of measuring the vertex power with a lateral resolution below one millimeter since this is sufficient for a functional test of progressive eyeglasses. Expressed in a more abstract way, the concept is based on a selection and thereby encoding of single sub-apertures of the wave front under test. This allows measuring the wave fronts slope consecutively in a scanning procedure. The use of high precision galvo systems allows a lateral resolution below one millimeter as well as a significant fast scanning ability. The measurement concept and performance of this method will be demonstrated for different spherical and freeformed specimens like progressive eye glasses. Furthermore, approaches for calibration of the measurement system will be characterized and the optical design of the detector will be discussed.

    Genital and perianal ulcers seen in patients with HIV are commonly due to herpes simplex virus (HSV) infection. While it is well known that the characteristic presentation of HSV is a vesicular rash or crops of erosions, the clinical presentation of genital HSV infection in HIV is varied and can assume vegetative, hypertrophic, condyloma-like, nodular, ulcerative and tumour-like nodules or plaques. These unusual presentations often lead to a delayed diagnosis. We describe five immunocompromised HIV-positive patients with CD4 counts ranging from 114 to 326 cells/μL with unusual presentations of anogenital herpes.

Patients were divided into 2 groups (with and without PAD). Out of 6705 consecutive ACS patients, PAD was reported in 177 patients. In comparison to non-PAD, PAD patients were older and more likely to have cardiovascular risk factors. They were more likely to have high Killip class, high GRACE risk score, and non-ST elevation ACS (NSTEACS) at presentation. Thrombolytics, antiplatelet use, and coronary intervention were comparable in both groups. When presented with ST-elevation myocardial infarction (STEMI), patients with PAD had worse outcomes, while in NSTEACS; PAD was associated with higher rate of heart failure in comparison to non-PAD patients. In diabetics, PAD was associated with 2-fold increase in mortality when compared to non-PAD (P = 0.028). After adjustment, PAD was associated with high mortality in STEMI (adjusted OR 2.6; 95% CI 1.23–5.65, P = 0.01). Prevalence of PAD in ACS in the Gulf region is low. Patients with PAD and ACS constitute a high risk group and require more attention. PAD in patients with STEMI is an independent predictor of in-hospital death. PMID:22220279

    The objective of the present study was to estimate the diagnostic potential of the Luscher color test. A total of 1083 patients presenting with chronic somatic diseases were available for the psychodiagnostic examination. It was shown that the color test makes it possible to evaluate clinically significant psychological characteristics as well as dynamics of anxiety and stress-resistance in this group of patients. Specifically, in the cases of chronic somatic diseases, the test can be used as one of the psychodiagnostic methods especially for mass screening and in the situations when the application of the standard questionnaires encounters difficulties (for example, in the patients with disturbed cognitive functions).

    OBJECTIVE. To review the clinical characteristics of patients presenting after centipede bites in Hong Kong. DESIGN. Descriptive case series. SETTING. Emergency departments of two public hospitals in Hong Kong. PATIENTS. Patients presenting after centipede bites between 2006 and 2010. MAIN OUTCOME MEASURES. Demographics, time and locations of bites, symptoms and signs, treatments and outcomes. RESULTS. A total of 46 relevant patient records were retrieved. The bites were frequently at night, indoors, on lower limbs, and consistently resulted in pain. The majority of the victims were treated with analgesia, anti-histamines, and antibiotics. One patient developed necrosis and five re-attended for delayed pruritus and relapsed/recurrent swelling. CONCLUSIONS. Centipede bites are usually uncomplicated, but may lead to necrosis or delayed hypersensitive reactions.

    Human herpes virus 6 (HHV-6) infections are frequently detected in patients with immunosuppressed transplant; however, reactivation in an immunocompetent patient is rarely reported. The author reports the case of a 65-year-old woman presenting with status epilepticus with foci in the temporal and occipital lobe and MRI suggestive of encephalitis in the parietal, occipital and temporal regions. The cerebrospinal fluid (CSF) analysis showed normal cell counts, protein and glucose levels and hence viral aetiologies were considered. The patient's workup returned positive for HHV-6 in serum as well as CSF. The patient responded well to a 21-day course of antivirals with complete resolution of her symptoms. This case highlights the importance of considering HHV-6 encephalitis even among immunocompetent patients presenting with encephalitis and having signs of temporal lobe involvement. PMID:25239996

    Abstract The purpose of this study was to investigate the relationship of alcohol intoxication to time-to-presentation following injury, fracture type, mechanism of injury leading to fracture, and initial diagnostic radiology interpretation performance of emergency physicians versus diagnostic radiologists in patients who present to the emergency department (ED) and are subsequently diagnosed with fracture. Medical records of 1286 patients who presented to the ED and were diagnosed with fracture who also underwent plain film or computed tomography (CT) imaging were retrospectively reviewed. The subjects were divided into intoxicated and sober groups. Patient characteristics, injury-to-presentation time, fracture location, and discrepancies between initial clinical and radiological evaluations were compared. Of 1286 subjects, 181 patients were included in the intoxicated group. Only intoxicated patients presented with head/neck fractures more than 24 hours after injury. The intoxicated group showed a higher rate of head/neck fractures (skull 23.2% vs 5.8%, face and orbit 30.4% vs 9.5%; P < 0.001) and a lower rate of extremity injuries. The rate of nondiagnosis of fractures by emergency physicians later identified by radiologists was the same in both groups (7.7% vs 7.7%, P = 0.984). While the same proportion of intoxicated patients presented more than 24 hours following injury, only intoxicated patients presented with craniofacial and cervical spinal fractures during this period. Alcohol-related injuries are more often associated with head/neck fractures but less extremity injuries. The rate of fractures missed by emergency physicians but later diagnosed by radiologists was the same in intoxicated and sober patients.

    Smart Ophthalmics© extends ophthalmic healthcare to people who operate/live in austere environments (e.g., military, third world, natural disaster), or are geographically dispersed (e.g., rural populations), where time, cost, and the possibility of travel/transportation make access to even adequate medical care difficult, if at all possible. Operators attach optical devices that act as ophthalmic examination extensions to smartphones and run custom apps to perform examinations of specific areas of the eye. The smartphone apps submit over wireless networks the collected examination data to a smart remote expert system, which provides in-depth medical analyses that are sent back in near real-time to the operators for subsequent triage.

    Differentiating acute Q fever from infections caused by other pathogens is essential. We conducted a retrospective case–control study to evaluate differences in clinical signs, symptoms, and outcomes for 82 patients with acute Q fever and 52 control patients who had pneumonia, fever and lower respiratory tract symptoms, or fever and hepatitis, but had negative serologic results for Q fever. Patients with acute Q fever were younger and had higher C-reactive protein levels but lower leukocyte counts. However, a large overlap was found. In patients with an indication for prophylaxis, chronic Q fever did not develop after patients received prophylaxis but did develop in 50% of patients who did not receive prophylaxis. Differentiating acute Q fever from other respiratory infections, fever, or hepatitis is not possible without serologic testing or PCR. If risk factors for chronic Q fever are present, prophylactic treatment is advised. PMID:26196955

    During peak ragweed season, 86 patients with seasonal allergic conjunctivitis participated in a 9-week, multicenter, double-masked, placebo-controlled, group-comparative study testing the efficacy and safety of bid nedocromil sodium, 2% ophthalmic solution. The clinical effectiveness of nedocromil sodium was measured by analyzing the means of patient daily symptom scores and eye examinations after 1, 3, 5, and 8 weeks of treatment. The use of nedocromil sodium during peak ragweed pollen season reduced symptom scores with statistically significant treatment differences as compared with the placebo for itchy eyes, tearing, overall eye condition, and symptom summary score. Clinician assessments also favored the use of nedocromil sodium as indicated by significant improvements in tearing, conjunctival injection, and conjunctival edema. No significant side effects were reported by the patients, allergists, or ophthalmologists. We conclude that nedocromil sodium, 2% ophthalmic solution, administered bid is more effective in the relief of symptoms of seasonal allergic conjunctivitis than placebo and causes no major side effects.

    On orbit, ophthalmic anesthetics are used for tonometry and off-nominal corneal examinations. Proparacaine has been flown traditionally. However, the manufacturers recently changed its storage requirements from room temperature storage to refrigerated storage to preserve stability and prolong the shelf-life. Since refrigeration on orbit is not readily available and there were stability concerns about flying proparacaine unrefrigerated, tetracaine was selected as an alternative ophthalmic anesthetic in 2013. We will discuss the challenges encountered flying and using these anesthetics on the International Space Station.

    Pseudohypoaldosteronism (PHA) is defined as a state of resistance to aldosterone, a hormone crucial for electrolyte equilibrium. The genetically transmitted type of PHA is primary hypoaldosteronism. Secondary hypoaldosteronism develops as a result of hydronephrosis or hydroureter. PHA patients suffer from severe hyponatremia and a severe clinical condition due to severe loss of salt can be encountered in the neonatal period. Dermal findings in the form of miliaria rubra can also develop in these patients. With the loss of salt, abnormal accumulation of sebum in the eye due to a defect in the sodium channels can also occur. In this paper, a case of PHA in a newborn showing typical dermatological and ophthalmological findings is presented. PMID:26316441

    2015-01-01

    Background: There is limited research related to spinal manipulation of uncomplicated thoracic spine pain and even less when pain is associated with comorbid conditions such as rheumatoid arthritis. In the absence of trial evidence, clinical experience and appropriate selection of the type of intervention is important to informing the appropriate management of these cases. Case presentation: We present a case of a patient with long standing rheumatoid arthritis who presented with acute thoracic pain. The patient was diagnosed with costovertebral joint dysfunction and a myofascial strain of the surrounding musculature. The patient was unresponsive to treatment involving a generalized manipulative technique; however, improved following the administration of a specific applied manipulation with modified forces. The patient was deemed recovered and discharged with ergonomic and home care recommendations. Discussion: This case demonstrates a clinical situation where there is a paucity of research to guide management, thus clinicians must rely on experience and patient preferences in the selection of an appropriate and safe therapeutic intervention. The case highlights the need to contextualize the apparent contraindication of manipulation in patients with rheumatoid arthritis and calls for further research. Finally the paper advances evidence based decision making that balances the available research, clinical experience, as well as patient preferences. PMID:26136606

    Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤ 30 years (early onset), age between 31 and 59 years (standard onset), and age ≥ 60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients.

    Available data correlating symptoms of colon cancer patients with the severity of the disease are very limited. In a population-based setting, we correlated information on symptoms of colon cancer patients with several pathological tumor parameters and survival. Information on all patients diagnosed with colon cancer in Iceland in 1995-2004 for this retrospective, population-based study was obtained from the Icelandic Cancer Registry. Information on symptoms of patients and blood hemoglobin was collected from patients' files. Pathological parameters were obtained from a previously performed standardized tumor review. A total of 768 patients entered this study; the median age was 73 years. Tumors in patients presenting at diagnosis with visible blood in stools were significantly more likely to be of lower grade, having pushing border, conspicuous peritumoral lymphocytic infiltration, and lower frequency of vessel invasion. Patients with abdominal pain and anemia were significantly more likely to have vessel invasion. Logistic regression showed that visible blood in stools was significantly associated with protecting pathological factors (OR range 0.38-0.83, p < 0.05). Tumors in patients presenting with abdominal pain were strongly associated with infiltrative margin and scarce peritumoral lymphocytic infiltration (OR = 1.95; 2.18 respectively, p < 0.05). Changes in bowel habits were strongly associated with vessel invasion (OR = 2.03, p < 0.05). Cox regression showed that blood in stools predicted survival (HR = 0.54). In conclusion, visible blood in stools correlates significantly with all the beneficial pathological parameters analyzed and with better survival of patients. Anemia, general symptoms, changes in bowel habits, acute symptoms, and abdominal pain correlate with more aggressive tumor characteristics and adverse outcome for patients.

    Outdoor music festivals are unique events given that they are, for the most part, bounded and ticketed, and alcohol is served. They frequently have a higher incidence of patient presentations when compared with similar types of mass gatherings. Often, however, single events are reported in the literature, making it difficult to generalize the findings across multiple events and limiting the understanding of the "typical" patient presentations at these mass gatherings. The aim of this paper was to understand the characteristics of young people who have presented as patients to on-site health care at outdoor music festivals in Australia, and the relative proportion and type of injury and illness presentations at these events. This research used a nonexperimental design, utilizing a retrospective review of patient report forms from outdoor music festivals. Data were collected from 26 outdoor music festivals across four States of Australia during the year 2010. Females presented at greater numbers than males, and over two-thirds presented with minor illnesses, such as headaches. Males presented with injuries, in particular lacerations to their face and their hands, and alcohol and substance use made up 15% of all presentations. PMID:24555927

    The authors describe a rare case of combined pituitary chronic lymphocytic leukemia (CLL) and prolactinoma in a 77-year-old man presenting with apoplexy. This case highlights the importance of evaluating the pituitary gland in patients with CLL who present with clinical manifestations of apoplexy as well as the need to carefully evaluate pathological specimens from the gland for the presence of lymphocytic cells in those patients. This is the first reported case of a combined CLL-prolactinoma pituitary lesion presenting with apoplexy.

    In two patients eclampsia started 9 days postpartum. Headache and visual disturbances preceded seizures but none of the classic pre-eclamptic signs oedema, proteinuria, and hypertension were present until shortly before seizure onset. Brain herniation (patient 1) and status epilepticus (patient 2) necessitated neurointensive care management. Brain MRI initially showed only frontal sulcal effacement in one patient but later showed white matter hyperintensities on T2 weighted images and a previously undescribed pattern of cortical-subcortical postgadolinium enhancement on T1 weighted images in both. Neurological deficits and MRI findings were reversed with therapy in both patients. It is concluded that late postpartum eclampsia can manifest without classic prodromi and that characteristic MRI findings may lag behind clinical manifestation.

    The introduction of modern heartworm, flea, and tick preventatives has provided a safe and effective means of controlling companion animal endoparasites, but achieving good owner compliance remains an ongoing challenge for the veterinary profession. Based on a sample of patients from the veterinary teaching hospital at the University of Pennsylvania, this study retrospectively examined factors associated with preventative use and areas of potential weakness in client communication. Between 1999 and 2006, records of 5,276 canine and 1,226 feline patients were searched for signalment, survey results for heartworm, flea, and tick preventative use, date of visit, presenting complaint, vaccination history, and owner zip code. Data were analyzed using bivariate and multivariate techniques. Overall, only 13 - 23 % of patients were questioned about heartworm, flea, or tick preventative use during routine medical history taking. Patients with a prior history of parasites, younger patients, or those presenting with signs of cardiac disease were no more likely to be questioned about preventative use than healthy animals. Patients presenting to a specialty service were also less likely to be questioned. Approximately 74 - 79% of dogs and 12 – 38 % of cats in the sample were on preventative products at any given time. There was a distinct seasonality to preventative use corresponding to the heartworm transmission season from June through November in the northeastern United States. Only 50% of patients seen for a yearly physical examination in winter were reported to be using preventative products when surveyed later in the year, compared to the roughly 85% on patients in heartworm preventatives when they received their routine physical exam in spring. Month of presentation and neuter status were the only signalment factors significantly (P<0.05) associated with preventative use in the multivariate analysis. Findings from this study emphasize target areas for increasing owner

    Dengue is an acute infectious disease of viral etiology. It is probably one of the most important arthropod borne viral disease in terms of human morbidity and mortality. The spectrum of disease ranges from self-limited dengue fever to more severe forms of dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Laboratory diagnosis of dengue virus infection mainly depends on detection of virus specific antibodies. The aim of the study was to correlate the serological results with clinical presentation in patients with a diagnosis of dengue. Eleven out of 15 (73.3%) patients with DHF and DSS had secondary antibody response and mortality was 100% in these patients.

    Abstract Objective: to relate complaints presented by emergency room patients, classified using the Manchester Triage System, with the final outcome (discharge/death/transfer). Methods: prospective cohort study, involving 509 patients who were admitted to the emergency room and remained there for more than 24 hours after admission, being monitored to the final outcome. Data were analyzed with a statistical program using descriptive and analytical statistics. Results: the mean age of the patients was 59.1 years and 59.3% were male. The main complaints were unwell adult (130 - 22.5%), shortness of breath in adults (81 - 14.0%), abdominal pain in adults (58 - 10.0%) and behaving strangely (34 - 5.9%), with 87% of the patients being discharged. More deaths were found in the patients classified in the severe colors, with 42.8% classified as red, 17.0% as orange and 8.9% as yellow. Among the patients classified as green, 9.6% died. Conclusion: in the various colors of the Manchester Triage System, death prevailed in patients that presented the complaints of unwell adult, shortness of breath, head injury, major trauma, diarrhea and vomiting. The higher the clinical priority the greater the prevalence of death. PMID:26444159

    Up to five percent of primary care consultations are eye-related, yet 96% of General Practitioners (GPs) do not undergo postgraduate ophthalmology training. Most do not feel assured performing eye assessments. Some red eye conditions can become sight threatening, and often exhibit red-flag features. These features include moderate pain, photophobia, reduced visual acuity (VA), eye-trauma, or unilateral marked redness. The aim of this project was to improve primary care assessment and referral of patients presenting with red-flag features based on the NICE 'Red Eye' Clinical Knowledge Summary recommendations. Data was collected retrospectively from 139 red eye consultations. A practice meeting highlighted poor awareness of red-flag features, low confidence levels in eye assessments, and time-constraints during appointments. Interventions were based on feedback from staff. These included a primary care teaching session on red-flag features, a VA measurement tutorial, and provision of a red eye toolkit, including VA equipment, to each consultation room. At baseline, each patient had on average 0.9 red-flag features assessed. Only 36.0% (9/25) of patients with red-flag features were appropriately referred to same-day ophthalmology services. Following two improvement cycles, a significant improvement was seen in almost every parameter. On average, each patient had 2.7 red-flag features assessed (vs 0.9, p<0.001). VA was assessed in 55.6% of consultations (vs 7.9%, p<0.001), pain was quantified in 81.5% (vs 20.9%, p=0.005), eye-trauma or foreign-body (51.8% vs 8.6%, p<0.001), extent of redness was documented in 66.7% (vs 14.4%, p<0.001). Only photophobia remained poorly assessed (18.5% vs 14.4%, p=0.75). Following this, 75.0% (6/8) of patients were appropriately referred. This project reflected the literature regarding low confidence and inexperience amongst GPs when faced with ophthalmic conditions. Improvements in education are required to ensure accurate assessments

    Background: The coexistance among fungal pathogens and tuberculosis pulmonary is a clinical condition that generally occurs in immunosuppressive patients, however, immunocompetent patients may have this condition less frequently. Objective: We report the case of an immunocompetent patient diagnosed with coinfection Mycobacterium tuberculosis and Candida albicans. Case Description: A female patient, who is a 22-years old, with fever and a new onset of hemoptysis. Clinical findings and diagnosis: Diminished vesicular breath sounds in the apical region and basal crackling rales in the left lung base were found in the physical examination. Microbiological tests include: chest radiography and CAT scan pictograms in high resolution, Ziehl-Neelsen stain, growth medium for fungus and mycobacteria through Sabouraudís agar method with D-glucose. Medical examinations showed Candida albicans fungus and Mycobacterium tuberculosis present in the patient. Treatment and Outcome: Patient was treated with anti-tuberculosis and anti-fungal medications, which produced good responses. Clinical relevance: Pulmonary tuberculosis and fungal co-infection are not common in immunocompetent patients. However, we can suspect that there is a presence of these diseases by detecting new onset of hemoptysis in patients. PMID:27546933

    Iatrogenic Cushing's syndrome (ICS) is caused by exogenous corticosteroid administration with suppression of the hypothalamic-pituitary-adrenal axis. It has been commonly described with oral and topical steroid use, but scarce reports have documented intranasal steroid usage as the etiology in infancy. In this article, we describe a case of a 4-month-old infant who developed ICS after 6 weeks of intranasal dexamethasone ophthalmic solution administration for nasal obstruction. To our knowledge, this is the youngest patient reported with ICS due to intranasal use of a prescribed dose of an ophthalmic steroid. His hypothalamic-pituitary-adrenal axis recovered fully 4.5 months after steroid discontinuation. Because of the small body surface area and supine position during administration, infants are particularly susceptible to ICS. Given that intranasal steroids are commonly prescribed to infants and children for a variety of diagnoses, this case highlights the risks inherent in the use of intranasal steroid drops, particularly in young infants, for both adrenal suppression and linear growth deceleration, even with short-term use. Close monitoring of these patients' height and weight should occur while on steroid treatment, with every effort made to decrease or discontinue steroid use when possible. PMID:27244810

    Introduction The purpose of this case report is to describe the clinical presentation, examination findings, and management decisions of a patient with thoracic myelopathy who presented to a chiropractic clinic. Case Report/Methods After receiving a diagnosis of a diffuse arthritic condition and kidney stones based on lumbar radiograph interpretation at a local urgent care facility, a 45-year-old woman presented to an outpatient chiropractic clinic with primary complaints of generalized low back pain, bilateral lower extremity paresthesias, and difficulty walking. An abnormal neurological examination result led to an initial working diagnosis of myelopathy of unknown cause. The patient was referred for a neurological consult. Results Computed tomography revealed severe multilevel degenerative spondylosis with diffuse ligamentous calcification, facet joint hypertrophy, and disk protrusion at T9-10 resulting in midthoracic cord compression. The patient underwent multilevel spinal decompressive surgery. Following surgical intervention, the patient reported symptom improvement. Conclusion It is important to include a neurologic examination on all patients presenting with musculoskeletal complaints, regardless of prior medical attention. The ability to recognize myelopathy and localize the lesion to a specific spinal region by clinical examination may help prioritize diagnostic imaging decisions as well as facilitate diagnosis and treatment.

    Background To evaluate the analgesic efficacy of bromfenac sodium ophthalmic solution 0.09% compared with ketorolac tromethamine ophthalmic solution 0.5% in laser epithelial keratomileusis (LASEK) or epithelial keratomileusis (epi-LASEK), sometimes referred to as epi-LASIK. Methods Eighty eyes (from 40 patients, 18 men and 22 women) undergoing bilateral simultaneous LASEK or epi-LASEK were randomized to receive ketorolac in one eye and bromfenac in the other. Mean age was 33.13 ± 9.34 years. One drop of bromfenac or ketorolac was instilled in each eye 15 minutes and one minute prior to surgery, and two and four hours following surgery. Patients were instructed to instill the medications on-label each day through postoperative day 4. The subjects completed pain and visual blurriness assessments from day of surgery to postoperative day 4. Uncorrected visual acuity was tested on postoperative days 1 and 6. Results For each of the five days, pain scores for bromfenac-treated eyes were significantly less than that for ketorolac-treated eyes (P < 0.01). Of the 40 patients, 32 (80%) said bromfenac provided better postoperative analgesia than ketorolac. There was no statistically significant difference in visual blurriness scores between the two groups (P > 0.1). Uncorrected visual acuity did not vary significantly between the treatment groups (P > 0.1). No serious adverse events were noted. Conclusion Bromfenac is subjectively superior to ketorolac in reducing postoperative pain following LASEK or epi-LASEK. The subjects tolerated the drugs well with no serious adverse outcomes and no difference in uncorrected visual acuity. PMID:22034570

    Background Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome (GTPS), though limited information exists on the disability associated with this condition and specific presentation of these patients. Purpose To describe the clinical, functional and biomechanical presentation of patients with symptomatic HAT tears. Secondary purposes were to investigate the association between these clinical and functional measures, and to compare the pain and disability reported by HAT tear patients to those with end-stage hip osteoarthritis (OA). Study Design Prospective case series. Methods One hundred forty-nine consecutive patients with symptomatic HAT tears were evaluated using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, an additional series of 10 questions more pertinent to those with lateral hip pain, active hip range of motion (ROM), maximal isometric hip abduction strength, six-minute walk capacity and 30-second single limb stance (SLS) test. The presence of a Trendelenburg sign and pelvis-on-femur (POF) angle were determined via 2D video analysis. An age matched comparative sample of patients with end-stage hip OA was recruited for comparison of all patient-reported outcome scores. Independent t-tests investigated group and limb differences, while analysis of variance evaluated pain changes during the functional tests. Pearson's correlation coefficients investigated the correlation between clinical measures in the HAT tear group. Results No differences existed in patient demographics and patient-reported outcome scores between HAT tear and hip OA cohorts, apart from significantly worse SF-12 mental subscale scores (p = 0.032) in the HAT tear group. Patients with HAT tears demonstrated significantly lower (p < 0.05) hip abduction strength and active ROM in all planes of motion on their affected limb. Pain significantly increased throughout the 30-second SLS test for the HAT tear group, with 57% of HAT tear patients

    Hypernatremia is a common electrolyte disorder associated with prolonged hospitalization and death. Severe hypernatremia is defined as a serum sodium (Na(+)) concentration >160 mmol/L. To the best of our knowledge, there is little information on patients with severe hypernatremia, Na(+) >160 mmol/L. Therefore, in this study, we aimed to determine the frequency, demographic and clinical characteristics, comorbid conditions and treatment strategies in patients presenting to the emergency department with severe hypernatremia, and also to evaluate the effects of these factors on mortality. A retrospective chart review was performed on patients presenting to the emergency department between January 2011 and June 2014. Patients with Na(+) >160 mmol/L were screened retrospectively via the hospital electronic information management system and patient medical record files. During the 3.5 years of screening, 256 patients (0.04 %) with Na(+) >160 mmol/L presented to the emergency department. The mean age of the patients included in the study was 74.4 ± 15.2 years, mean Na(+) level was 168.7 ± 7.4 mmol/L and, mean mortality was 49.5 % during the hospitalization. Multivariable Cox regression analysis showed that low systolic blood pressure, low pH, Na(+) >166 mmol/L, increased plasma osmolarity, mean sodium reduction rate ≤-0.134 mmol/L/h, dehydration, and, pneumonia to be independently associated with mortality. This study describes the demographic and clinical characteristics of patients with Na(+) >160 mmol/L in a large population along with comorbid conditions, incidence, treatment strategies and, its association with mortality.

    Fanconi-Bickel syndrome is a rare inherited disorder characterized by hepatorenal glycogen accumulation, renal tubular dysfunction, growth failure, and impaired utilization of glucose and galactose. We report the first two children with Fanconi-Bickel syndrome from Pakistan who presented with classical features of Fanconi-Bickel Syndrome. Both patients were found to be homozygous for a single nucleotide deletion in the SLC2A2 gene defined as c.339delC. This mutation was previously described in an Arab patient who was initially presented as permanent neonatal diabetes mellitus before developing classical features of Fanconi-Bickel syndrome.

    Sphingomonas paucimobilis, a yellow-pigmented, aerobic, glucose non-fermenting, Gram-negative bacillus, is a rare cause of human infection normally associated with immunocompromised hosts. We report a case of bacteraemia and septic arthritis in a 47-year-old diabetic man who presented with septic pulmonary emboli due to S. paucimobilis. The patient had an initial presentation of fever, right knee pain, coughing, dyspnoea and chest pain. The infection was treated successfully by surgical debridement combined with meropenem plus ciprofloxacin, based on the patient's antibiotic susceptibility profile. To our knowledge, this is the first case report for septic pulmonary emboli having arisen from an S. paucimobilis infection.

    Nocardiosis is an opportunistic infection caused by the Gram-positive weakly acid-fast, filamentous aerobic Actinomycetes. The lungs are the primary site of infection mainly affecting immunocompromised patients. In rare circumstances even immunocompetent hosts may also develop infection. Diagnosis of pulmonary nocardiosis is usually delayed due to nonspecific clinical and radiological presentations which mimic fungal, tuberculous, or neoplastic processes. The present report describes a rare bronchoscopic presentation of an endobronchial nocardial mass in a 55-year-old immunocompetent woman without underlying lung disease. The patient exhibited signs and symptoms of unresolving community-acquired pneumonia with a computed tomography (CT) scan that showed a space-occupying lesion and enlarged paratracheal lymph node. This patient represents the unusual presentation of pulmonary Nocardia beijingensis as an endobronchial mass. Pathology obtained during bronchoscopy demonstrated polymerase chain reaction (PCR) confirmation of nocardiosis. Symptoms and clinical findings improved with antibiotic treatment. This patient emphasizes the challenge in making the diagnosis of pulmonary nocardiosis, especially in a low risk host. A literature review presents the difficulties and pitfalls in the clinical assessment of such an individual. PMID:26819795

    This case report details an association of chronic allergic conjunctivitis and respiratory tract colonization in a cystic fibrosis (CF) patient due to an ethmoidal mucocele infected with Escherichia coli. A 3-year-old CF patient presented for evaluation with complaints of chronic periocular erythema, conjunctival injection, and irritation for 2 years. He was treated for presumed allergic conjunctivitis with no improvement and continued to have overall worsening of symptoms on the right greater than the left eye in a waxing and waning pattern. On presentation to the Bascom Palmer Eye Institute, he was noted to have telecanthus and prominent erythema in the region of the medial canthus. Orbital imaging disclosed a mucocele in the right ethmoid sinus. The patient underwent functional endoscopic sinus surgery, with successful marsupialization of the ethmoidal mucocele, which was found on culture to be infected with E. coli. Post-operatively with continuous pulmonary care, the patient remains free of allergic conjunctivitis and E. coli colonization of the upper airway. This case highlights the importance of analyzing the adjacent sinus in patients with chronic, relapsing allergic conjunctivitis refractory to medical management, particularly in patients with underlying systemic diseases such as CF.

    It is well established that clinicians cannot use clinical judgment alone to determine whether an individual patient who presents to the emergency department has an acute coronary syndrome. The history and physical examination do not distinguish sufficiently between the many conditions that can cause acute chest pain syndromes. Cardiac risk factors do not have sufficient discriminatory ability in symptomatic patients presenting to the emergency department. Most patients with non-ST-segment-elevation myocardial infarction do not present with electrocardiographic evidence of active ischemia. The improvement in cardiac troponin assays, especially in conjunction with well-validated clinical decision algorithms, now enables the clinician to rapidly exclude myocardial infarction. In patients in whom unstable angina remains a concern or there is a desire to evaluate for underlying coronary artery disease, coronary computed tomography angiography can be used in the emergency department. Once a process that took ≥24 hours, computed tomography angiography now can rapidly exclude myocardial infarction and coronary artery disease in patients in the emergency department. PMID:27528647

    Aim of the present study was to investigate the prevalence of allergy in patients affected by both organic and/or functional vocal fold disorders. The secondary aim was to assess the correlation between sex and allergy in dysphonic patients. A retrospective chart review was performed on dysphonic patients. A total of 76 patients underwent fiberoptic endoscopy to assess the objective picture. Logistic regression analyses have been conducted to assess the association between sex and the outcome variables. The laryngoscopic examination revealed the presence of poor glottic closure in 32.9%, hyperkinesias in 11.8%, redness in 11.84%, polyps in 5.3%, oedema in 3.95%, vocal fold hypertrophy in 5.3%, nodules in 42.1%, cordectomy in 2.6%. Allergic rhinitis was present in 56.6%, milk intolerance in 13.2%, asthma in 9.2%, atopic dermatitis in 3.9%, drugs intolerance in 11.8%. A total of 76.32% patients presenting with dysphonia were allergic. A statistically significant association was found between female sex and presence of allergy. In conclusion, allergy testing should be performed routinely on female professional voice users. Mild respiratory disorders must be taken into serious consideration in female professional voice users, who may primarily complain of vocal dysfunction rather than upper and lower respiratory diseases.

    Chest pain is a common general practice presentation that requires careful diagnostic assessment because of its diverse and potentially serious causes. However, the evaluation of acute chest pain remains challenging, despite many new insights over the past two decades. The percentage of patients presenting to the emergency departments because of acute chest pain appears to be increasing. Nowadays, there are two essential chest pain-related issues: 1) the missed diagnoses of acute coronary syndromes with a poor short-term prognosis; 2) the increasing percentage of hospitalizations of low-risk cases.It is well known that hospitalization of a low-risk chest pain patient can lead to unnecessary tests and procedures, with an increasing trend of complications and burden of costs. Therefore, the significantly reduced financial resources of healthcare systems induce physicians and administrators to improve the efficiency of care protocols for patients with acute chest pain. Despite the efforts of the Scientific Societies in producing statements on this topic, in Italy there is still a significant difference between emergency physicians and cardiologists in managing patients with chest pain. For this reason, the aim of the present consensus document is double: first, to review the evidence-based efficacy and utility of various diagnostic tools, and, second, to delineate the critical pathways (describing key steps) that need to be implemented in order to standardize the management of chest pain patients, making a correct diagnosis and treatment as uniform as possible across the entire country.

    Infection is a major problem after kidney transplantation. Cytomegalovirus (CMV) is the most common viral infection affecting transplant patients. This report presents a rare clinical manifestation of CMV in the form of a hemorrhoid in a 58-year-old woman. One week after undergoing an external hemorrhoidectomy, the patient presented with fever, leukopenia, and thrombocytopenia. Pathological analysis showed CMV in the hemorrhoidal tissue, which was confirmed via a positive PP65 antigenemia assay. Therapy with ganciclovir (250 mg IV b.i.d. for 2 weeks) was started. The patient's response to treatment was good, and she has been doing well since that time. Her plasma creatinine level 2 years later was 79.2 micromol/L (normal range, 53-106 micromol/L). Physicians must always be aware of the hazards of CMV in immunocompromised patients with typical, and even with atypical, presentations. Taking into consideration the statement, "prophylaxis precedes treatment," nephrologists must try to detect CMV in their patients (especially during the first 6 months after transplantation) prior to the appearance of any clinical manifestations. If CMV is detected, pre-emptive therapy with ganciclovir should be started.

    The effects of rasagiline on olfaction in animal studies are convincing. However, apart from various anecdotal patient reports, they could not be reproduced in prospective studies in humans. Cross-sectional data of large patient groups are still missing. The aim of this study was therefore to determine the olfactory function in a broad heterogeneous Parkinson's disease (PD) population with and without rasagiline intake. In this single-center, cross-sectional study 224 PD patients with and without rasagiline (1 mg/day) participated. Seventy-four of them received rasagiline as mono, or adjunct therapy. One-hundred fifty patients were untreated or received PD medication other than rasagiline. Comprehensive olfactory testing was performed for phenyl-ethyl alcohol odor thresholds, odor discrimination, and odor identification. Olfactory function did not differ between the two treatment groups with disease duration up to 29 years. Rasagiline-treated patients with disease duration of less than 8 years, however, presented with significant better odor discrimination abilities compared to PD patients without rasagiline treatment. This effect was no longer evident in patients with longer disease duration and proofed to be independent of age, sex, and medication. Our results may suggest that rasagiline treatment has a positive effect on the processing of olfactory information in early PD.

    Results of physical therapy evaluation of 112 patients with extensor mechanism disorders (chondromalacia patella, infrapatellar tendinitis, and peripatellar pain) are presented. An equal number of male and female patients were evaluated and of the 73 patients with unilateral involvement (65%) there were equal numbers of right and left involved knees. Running was the activity most commonly associated with pain, followed by basketball and tennis. Stairclimbing was painful in 79% of the patients, with ascending being more painful than descending in patients reporting a clear-cut difference. Hamstring and quadriceps tightness was statistically significant relative to the uninvolved limb although clinically, negligible differences were measured. The inferior pole of the patella was the most tender site to palpation, followed by medial peripatellar structures, then lateral sites. Biomechanical malalignment was not detected by the attending therapist in the majority of patients. The authors emphasize careful assessment of flexibility, quadriceps (VMOIVL) imbalance, and biomechanical alignment in performing a thorough evaluation of patients with extensor mechanism disorders.

    1983-01-01

    Eighty-one patients with diagnostically difficult clinical presentations suggesting coronary artery disease underwent symptom-limited maximal-exercise treadmill testing (ETT) and exercise radionuclide scanning with thallium-201 followed by coronary angiography. Results showed that in nearly half of the patients (47%) these tests were in agreement, while either exercise thallium or ETT was positive in 94% of patients with coronary artery disease. It was found that agreement between exercise thallium and ETT tests predicted disease in 92% of the instances or excluded disease in 82% of the instances. It is concluded that despite frequent discord between these two tests in 53% of the cases, a significant gain in exclusive diagnostic capability is realized when applied to a patient population anticipated to have a disease prevalence equal to the 67% encountered in this study.

    Primary contact health care practitioners can play an important role in work-related musculoskeletal disorders (WRMSDs) by recognizing and addressing occupational health issues. It is important to recognize ergonomics as a possible factor in patient health and recovery. A case is presented of a 36-year-old male suffering from neck and trapezius pain. Ergonomic factors at his musculoskeletal disorder. Conservative care and ergonomic changes to his workstation produced positive results leading to a full recovery. Practitioners should not ignore the possibility that the workplace may be a contributing factor in patients presenting with musculoskeletal complaints. A through patient history is the key to determining if musculoskeletal disorders are work-related. ImagesFigure 1Figure 2AFigure 2B

    Tuberculosis caused by Mycobacterium tuberculosis is a major public heath problem world-wide, particularly in low-income countries. Increased number of immunocompromised patients and immigration from countries where tuberculosis is endemic has resulted in increased number of cases in high-income countries. Tuberculosis can affect any organ system, but is of particular interest to chiropractors when it affects the neuromusculoskeletal system. Patients with tuberculosis of the neuromusculoskeletal system can present with mechanical low back pain or with complex neurologic deficits. The aim of this paper is to highlight the importance of considering a diagnosis of tuberculosis in susceptible populations and the devastating consequences of the disease. The epidemiology, clinical features and management of tuberculosis will also be presented to facilitate early diagnosis, appropriate referral and multidisciplinary care of these patients.

    The objective of the present study was to evaluate the clinical state of the larynx and its microbial population in 49 patients examined at the stage of stable condition of chronic obstructive pulmonary disease. Examination of the larynx was carried out with the use of a rigid laryngoscope having a visual angle of 70 degrees, videofibrolaryngoscopy, and stroboscopy using a «TelePac» videocomplex (Karl Storz, Germany). It was supplemented by the study of the bacteriological and mycological paysage. The acoustic analysis of the voice was performed with the help of the Specta PLUS computer program. It was shown that more than 70% of the examined patients presented with various forms of chronic laryngitis. Potentially pathogenic St. pyogenes and yeast-like fungi C. albicans were isolated from 59% and 29% of the patients respectively.

    Aseptic necrosis of the femoral head is a condition caused by partial or total interruption of blood supply to the femoral head. The diminished blood supply causes necrosis of the cellular elements and of the bone marrow, followed by the collapse of the bone structure, events that ultimately lead to the destruction of the bone tissue, the appearance of local pain and loss of function in the affected coxofemoral joint. The importance of this condition is that it mainly affects young adults aged 30-50 years, active from a socio-professional standpoint, and increased life expectancy. The material studied to achieve CD68 immunostaining was represented by bone fragments from the area of necrosis and from the adjacent areas of the femoral heads, harvested from 39 patients when performing hip arthroplasty surgery. The patients were diagnosed with aseptic necrosis of the femoral head and hospitalized in the Clinic of Orthopedics and Traumatology, Emergency County Hospital of Craiova, Romania, from June 2014 to January 2015. The 39 patients included in the study were divided into four categories according to presented risk factors (alcohol, alcohol and smoking, trauma, corticosteroids). All the 39 cases had positive immunostaining for CD68, macrophage being highlighted both in the area of necrosis and in the adjacent areas. We noted significant differences in the number and arrangement of macrophages in patients presenting different risk factors. The highest number of macrophages was present in patients presenting a risk factor corticosteroids, and the lowest number of macrophages was found in patients who had trauma as the main risk factor.

    The idiopathic inflammatory myopathies, including dermatomyositis, are uncommon acquired autoimmune diseases, sometimes associated with interstitial lung disease. Myasthenia gravis, a separate autoimmune disorder involving the neuromuscular junction, has some overlapping clinical features but has only rarely been reported to occur simultaneously within the same patient. Here we present the first reported case of concomitant dermatomyositis, myasthenia gravis, and interstitial lung disease. PMID:25473554

    Non-mydriatic ocular fundus photography is a promising alternative to direct ophthalmoscopy, particularly when combined with telemedicine. This review discusses these technologies from a longitudinal perspective: past, present, and future. The focus is directed to the role that non-mydriatic fundus photography and telemedicine have played in medical research and patient care, with emphasis on the major advances to date. Also discussed are the challenges to their widespread application and their substantial promise for revitalizing the importance of the ocular fundus examination in patient care, providing improved access to ophthalmic consultative services, and facilitating clinical and epidemiologic research.

    Purpose To compare the dose uniformity of difluprednate ophthalmic emulsion 0.05% (Durezol®) with both branded and generic prednisolone acetate ophthalmic suspension 1% under different simulated patient usage conditions. Methods Drug concentrations of difluprednate emulsion, branded prednisolone acetate suspension (Pred Forte®) and generic prednisolone acetate suspension following three storage conditions (upright, then shaken; upright, not shaken; inverted, not shaken) were analyzed by high performance liquid chromatography assay and results were reported as percent of declared concentration. Two drops were dispensed every four hours four times daily. Results Regardless of bottle orientation and shaking, all difluprednate emulsion concentrations at each time point analyzed were within 15% of declared concentration. Both branded and generic prednisolone acetate suspension concentrations varied substantially throughout the study. For the bottle stored upright and not shaken, 46% of the branded concentrations were not within 15% of declared concentration; for the bottle stored upright and shaken prior to use, 60% failed to meet this criterion. None of the branded concentrations from the inverted and not shaken bottle was within 15% of declared concentration. Generic prednisolone concentrations demonstrated the poorest dose uniformity, with 96% of the concentrations from the inverted and not shaken bottle not within 15% of declared concentration; 94% of the concentrations from the upright and shaken bottle and 87% from the upright and not shaken bottle similarly failed to meet this criterion. Conclusions Dose uniformity of Durezol emulsion was predictable in all simulated patient usage conditions, whereas the drop concentrations of Pred Forte and generic prednisolone acetate suspensions were highly variable throughout the study. Drop concentrations are more predictable with Durezol emulsion than with either prednisolone acetate suspension. PMID:20957058

    Levofloxacin 0.5% ophthalmic solution is a fluoroquinolone antibacterial agent with a broad spectrum of activity against Gram positive and negative bacteria. For those reasons it is highly effective in treating common external infections of the eye including blepharitis, conjunctivitis, keratitis. In terms of microbial eradication and clinical cure rate it is significantly more effective than ofloxacin 0.3% ophthalmic solution, and non inferior to moxifloxacin ophthalmic solution. After topical administration of levofloxacin 0.5% ophthalmic solution it achieves concentration exceeding MIC90 for most clinically relevant pathogenes in tears, conjunctiva, cornea as well as anterior chamber. Thus it can be used in prophylaxis in patients undergoing ocular surgery. Because of its postantibiotic effect and high concentration in tears three times daily regimen is as effective as most frequent administration in patients with conjunctivitis, which leads to better compliance. Despite the wide use of topical and systemic levofloxacin, most common ocular pathogens remain clinically susceptible. Topical levofloxacin is well tolerated, it rarely causes systemic or ocular adverse events with the majority of treatment-related adverse effects being of mild to moderate severity. It also does not effect the wound healing. PMID:26638552

    Objective: To report our experience with Fournier’s Gangrene (FG) over the past eight years and evaluate the predisposing factors which affect the mortality. Methods: Sixty-five patients who were admitted to emergency surgical unit of our institution presenting with FG between January 2006 and August 2014 were included. The anatomical site of infective gangrene, predisposing factors, etiological factors, and outcomes were retrospectively reviewed. Results: Our cases included 8 women and 57 men. The average age of men was 51±13.9 (range 19-75) and the average age of women was 63±10.5 (range 52-76). Average hospitalization time was 9.2±6.6 days (range 5-25) days. The most frequent comorbid disease was diabetes mellitus and the most frequent etiology was perianal abscess. Colostomy was performed in 11 patients, orchidectomy in two patients, cystostomy in two patients. Notably, all of the 8 (12.3%) patients who died from FG had diabetes and low socioeconomic status. A total of six patients who died required more than one surgical debridement. Conclusions: Fournier’s gangrene is a severe surgical emergency, with a high mortality rate. Low socioeconomic status, diabetes and more than one debridement play a major role in mortality and morbidity. PMID:27375726

    Accurate prognostic information is important in determining optimal management of patients presenting for evaluation of chest pain. In this study, the ability of exercise thallium-201 myocardial imaging to predict future cardiac events (cardiovascular death or nonfatal myocardial infarction) was correlated with clinical, coronary and left ventricular angiographic and exercise electrocardiographic data in 139 consecutive, nonsurgically managed patients followed-up over a 3 to 5 year period (mean follow-up, 3.7 +/- 0.9), using a logistic regression analysis. Among patients without prior myocardial infarction (100 of 139), the number of myocardial segments with transient thallium-201 defects was the only statistically significant predictor of future cardiac events when all patient variables were evaluated. Among patients with myocardial infarction before evaluation (39 of 139), angiographic ejection fraction was the only significant predictor of future cardiac events when all variables were considered. This study suggests an approach to evaluate the risk of future cardiac events in patients with possible ischemic heart disease.

    Currently, there are 5 existing classification criteria for gout: the Rome, New York, American Rheumatism Association (ARA), Mexico, and Netherlands criteria. This study was carried out to determine the performance of these classification criteria in Thai patients presenting with acute arthritis.All consecutive patients presenting with acute arthritis and being consulted at the Rheumatology Unit, Chiang Mai University Hospital from January 2013 to May 2015 were invited to join the study. Gout was defined by the presence of monosodium urate crystals in the synovial fluid or tissue examined by experienced rheumatologists. The 5 existing gout classification criteria were performed and evaluated in all of the patients, who were divided in subgroups of early disease (≤2 years), established disease (>2 years), and those without tophus.There were 136 gout and 97 nongout patients. Sensitivity and specificity across all criteria ranged from 75.7% to 97.1% and 68.0% to 84.5%, respectively. Overall, the Mexico criteria had the highest sensitivity (97.1%), and the ARA survey criteria the highest specificity (84.5%), whereas the Mexico criteria performed well in early disease with sensitivity and specificity of 97.1% and 81.7%, respectively. All 5 criteria showed high sensitivity (from 76.4% to 99.1%) but low specificity (from 30.8% to 65.4%) in established disease. In patients without tophus, the sensitivity and specificity ranged from 64.1% to 95.7% and 68.8% to 85.4%, respectively. The ARA survey criteria across all groups showed consistently high specificity for gout.The 5 existing classification criteria for gout had limited sensitivity and specificity in Thai patients presenting with acute arthritis. The ARA survey criteria are the most suitable for diagnosing gout in Thai people when crystal identification is not available.

    A medical student's ability to present a case history is a critical skill that is difficult to teach. Case histories presented without theatrical engagement may fail to catch the attention of their intended recipients. More engaging presentations incorporate 'stage presence', eye contact, vocal inflection, interesting detail and succinct, well organised performances. They convey stories effectively without wasting time. To address the didactic challenge for instructing future doctors in how to 'act', the Mayo Medical School and The Mayo Clinic Center for Humanities in Medicine partnered with the Guthrie Theater to pilot the programme 'Telling the Patient's Story'. Guthrie teaching artists taught storytelling skills to medical students through improvisation, writing, movement and acting exercises. Mayo Clinic doctors participated and provided students with feedback on presentations and stories from their own experiences in patient care. The course's primary objective was to build students' confidence and expertise in storytelling. These skills were then applied to presenting cases and communicating with patients in a fresher, more engaging way. This paper outlines the instructional activities as aligned with course objectives. Progress was tracked by comparing pre-course and post-course surveys from the seven participating students. All agreed that the theatrical techniques were effective teaching methods. Moreover, this project can serve as an innovative model for how arts and humanities professionals can be incorporated for teaching and professional development initiatives at all levels of medical education.

    Chromosome 22q11.2 deletion syndrome is a clinically heterogeneous condition of intellectual disability, parathyroid and thyroid hypoplasia, palatal abnormalities, cardiac malformations and psychiatric symptoms. Hyperphagia and childhood obesity is widely reported in Prader-Willi Syndrome (PWS) but there is only one previous report of this presentation in chromosome 22q11.2 deletion syndrome. We describe two further cases of chromosome 22q11.2 deletion syndrome in which hyperphagia and childhood obesity were the presenting features. This may be a manifestation of obsessive behaviour secondary to some of the psychiatric features commonly seen in chromosome 22q11.2 deletion syndrome. Serious complications may result from hyperphagia and childhood obesity therefore early recognition and intervention is crucial. Due to the similar clinical presentation of these two patients to patients with PWS, it is suggested that the hyperphagia seen here should be managed in a similar way to how it is managed in PWS.

    Fibromuscular dysplasia (FMD) is a well-known disease, but its diagnosis can be challenging. Typically, the symptomatic FMD are reported by young and middle aged people with high blood pressure refractory to medical treatment. We present a rare case of a young, healthy, and normotensive patient who presented with pain secondary to renal infarction, without any prior signs or symptoms or history of hypertension. This presentation of FMD has not been previously described. The typical but subtle angiographic findings of the macro-aneurysmal FMD as well as the successful endovascular treatment are discussed herein. The macro-aneurysmal form of FMD should be considered in the differential diagnosis of acute renal infarction in young and middle aged patients even if they do not have a history of hypertension.

    This paper presents the findings of a qualitative project conducted to investigate the education and training requirements that non-mental health trained emergency nurses need to enable them to effectively care for psychiatric patients presenting to a West Australian emergency department. Non-mental health trained nurses are ill-equipped in their psychiatric knowledge, assessment and communication skills to provide best possible care to the one in ten patients presenting to the emergency department with a complex mental health issue. The area of assessment and management of mental health patients in the emergency department is a complex one and staff are required to assess, triage and manage these patients appropriately. Furthermore, with aggression and violence increasing, emergency department nurses are concerned about their safety in the workplace. Focus groups with emergency nurses and semi-structured interviews with subject matter experts were conducted at one West Australian teaching hospital. The findings of the project demonstrated that these nurses considered that customer focus, workplace aggression and violence, psychiatric theory, mental health assessment and chemical dependence as key learning areas. These findings will form a platform for further education and training for ED staff.

    To advocate patient's right is an inevitable assignment of all neurologists who have clinical activities for patients with neurological diseases, though the assignment has very broad fields and is impossible to perform by one. The author summarized present issues of guardianship, the program to protect the social welfare rights in communities, and advance directives for patients with neurological diseases. The new guardianship for adults in Japan started in 2000 and has been increasingly used mainly for the demented. Proxy decision making for a medical care by the guardian is still unsettled. The author raised a possible question on identification of the person who wants medical certification for guardianship and his her intention to obtain such a document, in order to avoid unexpected troubles in the family or involved parties. Replies about the identification from an inspector at a family court, lawyers, judicial scriveners, social workers and Japan National Council of Social Welfare were shown on the table. In May 2007, the Ministry of Health. Labour and Welfare presented the guideline of process to decide the end-of-life-care. But advance directives for medical cares are still controversial in Japan. Multidisciplinary team to advocate patients' rights was stressed in this presentation.

    Gardner's syndrome is an autosomal dominant disease characterized by the presence of colonic polyposis, osteomas, and a multitude of soft-tissue tumors. Dental anomalies are present in estimated 30% of all affected individuals of Gardner's syndrome, so dental professionals play an important role in determining the early signs of the syndrome. The intestinal polyps have a 100% risk of undergoing malignant transformation if not treated thus, early diagnosis and regular surveillance are important. In this report, we describe classical presentation of Gardner's syndrome in a patient who presented with bilateral swellings on palate along with multiple impacted teeth. PMID:27307686

    Eighty-one patients with diagnostically difficult clinical presentations suggesting coronary disease underwent symptom-limited maximal-exercise treadmill testing (ETT) and exercise radionuclide scanning with /sup 201/Tl. Results of these tests were in agreement in only 47 percent of the cases. Either exercise thallium or ETT was positive in 94 percent of patients with disease. Among a population with a disease prevalence of 67 percent, agreement between exercise thallium an ETT predicted disease in 92 percent of instances or excluded disease in 82 percent of instances. Frequent discordance between these two tests in 53 percent of the cases unfortunately limits this usefulness.

    ABSTRACT Purpose: To evaluate the presentation and early surgical outcomes of elderly patients undergoing adrenalectomy for phaeochromocytoma. Patients and Methods: A retrospective search was performed of our adrenal disorders database for patients who underwent surgery for phaeochromocytoma or paraganglioma between 2009 and 2014. Patients >60 years old were classified as elderly. The clinical manifestations, intraoperative course, and early postoperative outcomes of elderly patients were compared to those of younger individuals (<60 years old). Results: The mean (±standard deviation) age in the older (n=10) and younger (n=36) groups was 69.6±5.3 years and 34.0±12.9 years. Germ-line mutations were more common in younger patients (50.0% versus 0%; p=0.004), whereas incidental lesions were more common in the elderly (40.0% versus 5.3%; p=0.003). In both groups, surgery was most commonly performed by videolaparoscopy (90% in the elderly and 82% in the younger group), with similar intraoperative anesthetic and surgical outcomes. Postoperatively, the older group more commonly received vasoactive drugs (60.0% versus 10.5%; p<0.001) and had a longer intensive care unit stay (3.1±2.8 versus 1.4±1.0 days; p=0.014), more clinical complications (60% versus 18.9%; p=0.01), and longer hospital stay (10.2±8.4 versus 5.7±4.9 days; p=0.028). Conclusions: Although all patients received the same preoperative preparation, the elderly group exhibited a slower and more complicated recovery after adrenalectomy. Meticulous perioperative care should be used in the elderly when treating phaeochromocytoma; nevertheless, adrenalectomy is a relatively safe procedure in this patient population. PMID:27564276

    The safety of alternative vitamin K antagonist (VKA) reversal strategies in patients with left ventricular assist devices (LVAD's) who present with intracranial hemorrhage (ICH) are not well known. A review of LVAD patients with ICH from May 2008 to 2015 was conducted, comparing the safety and efficacy of 4-factor prothrombin complex concentrate-assisted VKA reversal (4F-PCC group, n = 10) to reversal with traditional agents alone (no-PCC group, n = 10). An analysis of a no-reversal strategy in selected patients (n = 11) with ICH was additionally performed. Thirty-one cases of ICH on LVAD support were reviewed. The rate of post reversal thromboembolic events was not significantly different between 4F-PCC and no-PCC patients (0% vs. 10%, p = 1.0); however, the time to VKA reversal was shorter (474 vs. 945 minutes, p = 0.02) and fresh frozen plasma (FFP) requirements lower (1.9 vs. 3.6 units, p = 0.05) in 4F-PCC patients, with no difference in mortality between groups (p = 1.0). Eleven patients (mean ICH volume: 0.4 cm) were successfully managed without active VKA reversal, with no increased hemorrhage noted on neuroimaging. These results suggest that 4F-PCC-assisted reversal in LVAD patients is safe and may improve the efficacy of VKA reversal. Our findings also indicate that carefully selected patients with small ICH volumes may be safely managed by discontinuing anticoagulation and allowing the international normalized ratio (INR) to normalize physiologically.

    Background and Objectives: Prehospital transport practices prevalent among children presenting to the emergency are under-reported. Our objectives were to evaluate the prehospital transport practices prevalent among children presenting to the pediatric emergency and their subsequent clinical course and outcome. Methods: In this prospective observational study we enrolled all children ≤17 years of age presenting to the pediatric emergency (from January to June 2013) and recorded their demographic data and variables pertaining to prehospital transport practices. Data was entered into Microsoft Excel and analyzed using Stata 11 (StataCorp, College Station, TX, USA). Results: A total of 319 patients presented to the emergency during the study period. Acute gastroenteritis, respiratory tract infection and fever were the most common reasons for presentation to the emergency. Seventy-three (23%) children required admission. Most commonly used public transport was auto-rickshaw (138, 43.5%) and median time taken to reach hospital was 22 min (interquartile range: 5, 720). Twenty-six patients were referred from another health facility. Of these, 25 were transported in ambulance unaccompanied. About 8% (25) of parents reported having difficulties in transporting their child to the hospital and 57% (181) of parents felt fellow passengers and drivers were unhelpful. On post-hoc analysis, only time taken to reach the hospital (30 vs. 20 min; relative risk [95% confidence interval]: 1.02 [1.007, 1.03], P = 0.003) and the illness nature were significant (45% vs. 2.6%; 0.58 [0.50, 0.67], P ≤ 0.0001) on multivariate analysis. Conclusions: In relation to prehospital transport among pediatric patients we observed that one-quarter of children presenting to the emergency required admission, the auto-rickshaw was the commonest mode of transport and that there is a lack of prior communication before referring patients for further management.

    We report two cases of myotonic dystrophy in one family; both diagnosed from genetic analysis following ophthalmic indications, but before the manifestation of systemic symptoms. A 39-year-old female visited our clinic for routine examination. Mild ptosis, sluggish pupillary response, and bilateral snowflake cataracts were found. Fundus examination revealed an increased cup-to-disc ratio (CDR) in both eyes and a defect in the retinal nerve fiber layer in the right eye. Intraocular pressure was low, but within the normal range in both eyes. Because cataracts are characteristic of myotonic dystrophy, we suggested that her 14-year-old daughter, who did not have any systemic complaints, undergo ophthalmic examination. She also had mild ptosis and snowflake cataracts. Both patients underwent genetic evaluation and were diagnosed with myotonic dystrophy caused by unstable expansion of cytosine-thymine-guanine trinucleotide repeats in the dystrophia myotonica-protein kinase gene. Ophthalmologists can diagnose myotonic dystrophy based on clinical and genetic findings, before the manifestation of systemic abnormalities. PMID:27609169

    Sixteen adult captive bald eagles (Haliaeetus leucocephalus) underwent a complete bilateral ocular examination to assess normal ocular parameters and describe ophthalmic lesions. Tear production was measured with the Schirmer tear test 1 and intraocular pressure was measured with applanation tonometry. The menace response was normal bilaterally in 13 of 16 eagles. Two birds had normal menace responses despite having fundic lesions, and 2 birds with an inconsistent or absent menace response did not have appreciable ophthalmic lesions. Mean (SD) tear production was 14 +/- 2 mm/min (range, 8-19 mm/min). Mean intraocular pressure was 21.5 +/- 1.7 mm Hg (range, 15-26 mm Hg). At least 1 ocular lesion was present in 50% of examined eyes. Cataracts, the most common lesion observed, were present in 8 eyes of 5 birds. Three of 4 known geriatric birds were or had been affected with bilateral cataracts. Overall, ocular lesions are common in captive bald eagles, and cataracts appear to be more prevalent in geriatric bald eagles. An obvious positive menace response is present in most visual birds but may be absent in some eagles that are either normal or that do not have appreciable ophthalmic lesions. Applanation tonometry and the Schirmer tear test 1 can be performed easily on adult bald eagles and provide reproducible results.

    1. A 12 week prospective survey of all patients of any age with confirmed or suspected poisoning presenting to six accident and emergency departments in the North East of England was performed to establish the local incidence and patterns of presentation of poisoning. 2. 945 episodes of poisoning involving 852 patients were recorded representing approximately 1.2% of all A&E presentations and suggesting an annual attendance rate of 2.7 per 1000 persons per year. 3. Attendance rates varied threefold between hospitals and were similar in males and females overall; between the ages of five and 14 attendances were more common in females (1.9 vs 0.6/10(3)/y) while between 0 and 4 y (3.1 vs 2.4) and 25 and 34 y (3.9 vs 2.9/10(3)/y) they were more common in males. 4. The median interval between poisoning and presentation was 2 h (mean 4.1 h) and only 19% of cases presented within 1 h. Presentation was most common between Friday evening and Tuesday morning and in the late afternoon and evening. 5. 6% of the patients presented more than once with poisoning during the study period and 37% had a past history of deliberate self-harm. The most common poisons involved were paracetamol (43%), opioids (15%) and benzodiazepines (15%). 6. The study illustrates the frequency of presentations of poisoning to A&E departments. The high rate of poisoning in young men and the increasing use of paracetamol are particular causes for concern. PMID:8793528

    Cemento-osseous dysplasias are sometimes seen on routine radiographic examination of the tooth-bearing areas of the jaws, most commonly amongst adult female patients. Lesions present as radiolucent to radio-opaque areas, depending on various levels of maturity. Extraction of teeth is strongly contraindicated because there is a high risk of infection with a possibility of bone sequestration, as antibiotics are unable to cross the thick cortical marginal bone that surrounds these lesions. No report has been found in the literature on the orthodontic management of patients with this condition. This paper reports on a 28-year-old black female patient with cemento-osseous dysplasia who received orthodontic treatment.

    Extraocular retinoblastoma is a major challenge worldwide, especially in developing countries. Current treatment involves the administration of systemic chemotherapy combined with radiation, but there is a clear need for improvement of chemotherapy bioavailability in the optic nerve. Our aim was to study the ophthalmic artery chemosurgery (OAC) local route for drug delivery assessing ocular and optic nerve exposure to chemotherapy and to compare it to exposure after intravenous infusion (IV) of the same dose in an animal model. Topotecan was used as a prototype drug that is active in retinoblastoma and based on the extensive knowledge of its pharmacokinetics in preclinical and clinical settings. Five Landrace pigs received 4mg of topotecan via OAC as performed in retinoblastoma patients. At the end of the infusion, the eyes were enucleated, the optic nerve and retina were dissected, and the vitreous and plasma were separated. After recovery and a wash-out period, the animals received a 30-min IV infusion of topotecan (4 mg). The remaining eye was enucleated and tissues and fluids were separated. All samples were stored until quantitation using HPLC. A significantly higher concentration of topotecan in the optic nerve, vitreous, and retina was obtained in eyes after OAC compared to IV infusion (p<0.05). The median (range) ratio between topotecan concentration attained after OAC to IV infusion in the optic nerve, retina and vitreous was 84(54–668), 143(49–200) and 246(56–687), respectively. However, topotecan systemic exposure after OAC and IV infusion remained comparable (p>0.05). The median optic nerve-to-plasma ratio after OAC and IV was 44 and 0.35, respectively. Topotecan OAC delivery attained an 80-fold higher concentration in the optic nerve compared to the systemic infusion of the same dose with similar plasma concentrations in a swine model. Patients with retinoblastoma extension into the optic nerve may benefit from OAC for tumor burden by increased

    HIV-related eye disease can be classified as retinal HIV microangiopathy, opportunistic infections, neuro-ophthalmic manifestations and unusual malignancies. There is a 52-100% lifetime accumulative risk of HIV patients developing eye problems. Seventy-seven per cent of patients with ocular manifestations of HIV had CD4 counts < 200 cells/μL. Cytomegalovirus (CMV) is the most prevalent opportunistic infection, however, Africa has a low incidence of this, and more commonly squamous cell carcinoma, compared to the western hemisphere. Due to highly active antiretroviral therapy (HAART), the anti-CMV therapy may be discontinued if the CD4+ T cell count is > 100 cells/μL for a minimum of three months. Despite HAART, patients with a CD4 count < 50 cells/μL have a similar risk of developing CMV retinitis as compared to the pre-HAART era. Opportunistic infections include CMV, herpetic retinopathy (progressive outer retinal necrosis - PORN), less commonly toxoplasmosis, pneumocystis and cryptococcus. Malignancies associated with HIV include Kaposi's sarcoma and conjunctival squamous cell carcinoma. Cranial nerve palsies, optic disc swelling and atrophy are characteristic neuro-ophthalmic features. They usually occur secondary to meningitis/encephalitis (from cryptococcus and tuberculosis). With the advent of HAART, new complications have developed in CMV retinitis: immune recovery uveitis (IRU) and cystoid macula oedema (CMO). Immune recovery uveitis occurs in 71% of patients if HAART is started before the induction of the anti-CMV treatment. However, this is reduced to 31% if HAART is started after the induction treatment. Molluscum contagiosum and Kaposi's sarcoma can spontaneously resolve on HAART. Highly active anti-retroviral therapy has reduced the frequencies of opportunistic infections and improved the remission duration in HIV patients. PMID:24756590

    Purpose To investigate the clinical characteristics of X-linked retinoschisis (XLRS) and identify genetic mutations in Taiwanese patients with XLRS. Methods This study included 23 affected males from 16 families with XLRS. Fundus photography, spectral domain optical coherent tomography (SD-OCT), fundus autofluorescence (FAF), and full-field electroretinograms (ERGs) were performed. The coding regions of the RS1 gene that encodes retinoschisin were sequenced. Results The median age at diagnosis was 18 years (range 4–58 years). The best-corrected visual acuity ranged from no light perception to 20/25. The typical spoke-wheel pattern in the macula was present in 61% of the patients (14/23) while peripheral retinoschisis was present in 43% of the patients (10/23). Four eyes presented with vitreous hemorrhage, and two eyes presented with leukocoria that mimics Coats’ disease. Macular schisis was identified with SD-OCT in 82% of the eyes (31/38) while foveal atrophy was present in 18% of the eyes (7/38). Concentric area of high intensity was the most common FAF abnormality observed. Seven out of 12 patients (58%) showed electronegative ERG findings. Sequencing of the RS1 gene identified nine mutations, six of which were novel. The mutations are all located in exons 4–6, including six missense mutations, two nonsense mutations, and one deletion-caused frameshift mutation. Conclusions XLRS is a clinically heterogeneous disease with profound phenotypic inter- and intrafamiliar variability. Genetic sequencing is valuable as it allows a definite diagnosis of XLRS to be made without the classical clinical features and ERG findings. This study showed the variety of clinical features of XLRS and reported novel mutations. PMID:25999676

    Background Despite effective anti-TB treatments, tuberculosis remains a serious threat to public health and is associated with high mortality. Old age and multiple co-morbidities are known risk factors for death. The association of clinical presentations with mortality in pulmonary tuberculosis patients remains an issue of controversy. Methods This prospective observational study enrolled newly diagnosed, culture-proven pulmonary tuberculosis patients from five medical centers and one regional hospital, which were referral hospitals of TB patients. Radiographic findings and clinical symptoms were determined at the time of diagnosis. Patients who died for any reason during the course of anti-TB treatment were defined as mortality cases and death that occurred within 30 days of initiating treatment was defined as early mortality. Clinical factors associated with overall mortality and early mortality were investigated. Results A total of 992 patients were enrolled and 195 (19.7%) died. Nearly one-third (62/195, 31.8%) of the deaths occurred before or within 30 days of treatment initiation. Older age (RR = 1.04, 95%CI: 1.03–1.05), malignancy (RR = 2.42, 95%CI: 1.77–3.31), renal insufficiency (RR = 1.77, 95%CI: 1.12–2.80), presence of chronic cough (RR = 0.63, 95%CI: 0.47–0.84), fever (RR = 1.45, 95%CI: 1.09–1.94), and anorexia (RR = 1.49, 95%CI: 1.07–2.06) were independently associated with overall mortality. Kaplan-Meier survival analysis demonstrated significantly higher mortality in patients present with fever (p<0.001), anorexia (p = 0.005), and without chronic cough (p<0.001). Among patients of mortality, those with respiratory symptoms of chronic cough (RR = 0.56, 95%CI: 0.33–0.98) and dyspnea (HR = 0.51, 95%CI: 0.27–0.98) were less likely to experience early mortality. The radiological features were comparable between survivors and non-survivors. Conclusions In addition to demographic characteristics, clinical

    In this work, we describe the association between a germline RB1 mutation and disease presentation characteristics of retinoblastoma. The study evaluates a retrospective cohort of 164 of the 295 patients with retinoblastoma who were treated at a single center between 1988 and 2013 and who were referred for genetic evaluation. Peripheral blood was evaluated for RB1 mutations via Multiplex Ligation-dependent Probe Amplification (MLPA), sequencing, and detection of recurrent CpG transition mutations. Patients with an RB1 mutation were compared to patients without a mutation, regarding epidemiological factors and clinical presentation. Genetic analysis was completed for 149 patients. An RB1 mutation was identified in 76 children (51.0%) including 90.0% of the bilateral patients, and 19.8% of the unilateral unifocal patients (24.7% if we include the unilateral multifocal cases). The most common mutations were a stop codon (38.2%), a splicing error (19.7%) and a large deletion (15.8%). The mutation type correlated only with sex (Likelihood ratio, p = 0.0240) and with macular involvement (Likelihood ratio, p = 0.0591 and Fisher's exact one tail test p = 0.0459 for more macular involvement if there are germline mutations). It did not correlate with laterality, with the reason for referral, or with diagnosis age. However, identification of a mutation was more common in babies diagnosed under one year of age (Likelihood ratio, p < 0.0001). In conclusion, we were surprised that our genetic tests have also found mutations in 24.7% of patients with unilateral retinoblastoma in addition to most of the bilateral children. These unilateral patients with a germline mutation have an increased risk for other cancers throughout their lives, and their first-degree relatives have an increased risk for retinoblastoma. Therefore, genetic testing for RB1 mutation should be offered to all patients, including the unilateral cases. PMID:27068507

    Background The rising prevalence of diabetes mellitus (DM) worldwide, especially in developing countries, and the persistence of tuberculosis (TB) as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil. Methods We performed a retrospective analysis of a TB patient cohort (treatment naïve) of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT) initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups. Results DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups. Conclusions These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB

    One hundred and twenty two patients who were presenting with chronic persistent cough for more than 3-4 weeks were studied. Using anatomical and stepwise approach, we could identify the cause of chronic cough in 96% of the patients. The most common causes were due to postnasal drip syndrome (PND) (45%) and bronchial asthma (26%). We also demonstrated the important role of methacholine inhalation challenge in the diagnostic work up. The procedure could identify the patients who had bronchial hyperresponsiveness (BHR) in 52% of the cases. The severity degree of the BHR was classified into three levels. Mild or nonspecific BHR was defined as PC20 16-25 mg/ml. This could be found in many diseases such as PND and bronchiectasis. Moderate degree of BHR (PC20 8-16 mg/ml) was found in patients with PND and asthma. PC20 of less than 8 mg/ml was considered to be the most severe degree and it seemed to be specific for the diagnosis of asthma (positive predictive value 100%). Other condition that caused chronic cough were drug-induced, especially angiotensin-converting enzyme inhibitors, gastroesophageal reflux disease (GERD), idiopathic pulmonary fibrosis, subgottic cancer and idiopathic cough. These conditions may require invasive diagnostic work up, such as fiberoptic bronchoscopy and tissue biopsy. The treatment of chronic cough was according to the etiology. Thus, the patients presenting with chronic cough should be investigated to identify the cause, and it was not just only the administration of cough suppressant drugs in these patients. PMID:9251842

    Background Most acute febrile illnesses (AFI) are usually not associated with a specific diagnosis because of limitations of available diagnostics. This study reports on the frequency of EBV viremia and viral load in children and adults presenting with febrile illness in hospitals in Kenya. Methodology/Principal Findings A pathogen surveillance study was conducted on patients presenting with AFI (N = 796) at outpatient departments in 8 hospitals located in diverse regions of Kenya. Enrollment criterion to the study was fever without a readily diagnosable infection. All the patients had AFI not attributable to the common causes of fever in Kenyan hospitals, such as malaria or rickettsiae, leptospira, brucella and salmonella and they were hence categorized as having AFI of unknown etiology. EBV was detected in blood using quantitative TaqMan-based qPCR targeting a highly conserved BALF5 gene. The overall frequency of EBV viremia in this population was 29.2%, with significantly higher proportion in younger children of <5years (33.8%, p = 0.039) compared to patients aged ≥5 years (26.3% for 5–15 years or 18.8% for >15 years). With respect to geographical localities, the frequency of EBV viremia was higher in the Lake Victoria region (36.4%), compared to Kisii highland (24.6%), Coastal region (22.2%) and Semi-Arid region (25%). Furthermore, patients from the malaria endemic coastal region and the Lake Victoria region presented with significantly higher viremia than individuals from other regions of Kenya. Conclusions/Significance This study provides profiles of EBV in patients with AFI from diverse eco-regions of Kenya. Of significant interest is the high frequency of EBV viremia in younger children. The observed high frequencies of EBV viremia and elevated viral loads in residents of high malaria transmission areas are probably related to malaria induced immune activation and resultant expansion of EBV infected B-cells.

    Given that Campylobacter jejuni is recognized as the most common cause of bacterial gastroenteritis worldwide, recent findings showing comparable levels of Campylobacter concisus in patients with gastroenteritis would suggest that this bacterium is clinically important. The prevalence and abundance of Campylobacter concisus in stool samples collected from patients with acute gastroenteritis was examined using quantitative real-time PCR. The associated virulence determinants exotoxin 9 and zonula occludens toxin DNA were detected for Campylobacter concisus-infected samples using real-time PCR. Campylobacter concisus was detected at high prevalence in patients with gastroenteritis (49.7 %), higher than that observed for Campylobacter jejuni (∼5 %). The levels of Campylobacter concisus were putatively classified into clinically relevant and potentially transient subgroups based on a threshold developed using Campylobacter jejuni levels, as the highly sensitive real-time PCR probably detected transient passage of the bacterium from the oral cavity. A total of 18 % of patients were found to have clinically relevant levels of Campylobacter concisus, a significant number of which also had high levels of one of the virulence determinants. Of these patients, 78 % were found to have no other gastrointestinal pathogen identified in the stool, which strongly suggests a role for Campylobacter concisus in the aetiology of gastroenteritis in these patients. These results emphasize the need for diagnostic laboratories to employ identification protocols for emerging Campylobacter species. Clinical follow-up in patients presenting with high levels of Campylobacter concisus in the intestinal tract is needed, given that it has been associated with more chronic sequelae. PMID:26698172

    Given that Campylobacter jejuni is recognized as the most common cause of bacterial gastroenteritis worldwide, recent findings showing comparable levels of Campylobacter concisus in patients with gastroenteritis would suggest that this bacterium is clinically important. The prevalence and abundance of Campylobacter concisus in stool samples collected from patients with acute gastroenteritis was examined using quantitative real-time PCR. The associated virulence determinants exotoxin 9 and zonula occludens toxin DNA were detected for Campylobacter concisus-infected samples using real-time PCR. Campylobacter concisus was detected at high prevalence in patients with gastroenteritis (49.7 %), higher than that observed for Campylobacter jejuni (∼5 %).

    Objective To describe the complexity of somatizing patients’ symptomatology and the difficulties involved in the diagnostic process. Design Cross-sectional study of patients with medically unexplained symptoms. Setting Basque Health Service primary care centres in Bizkaia, Spain. Subjects The study comprised 156 patients selected at random from a list of 468 patients who had presented, over the course of their lives, six or more medically unexplained somatic symptoms for females and four or more for males, identified retrospectively by their practitioners. Main outcome measures Physicians interviewed these patients using the somatoform symptoms section of the Composite International Diagnostic Interview (CIDI), and the Primary Care Evaluation of Mental Disorders (PRIME-MD). The Medical Outcomes Survey Short Form 36 (SF-36) was filled in at home. Organic diseases whose diagnosis was established during the previous year were included in the study by consulting patients’ medical records. Results Patients were found to have a median of three medically explained and 12 medically unexplained symptoms. Mental disorders were found in 83% of cases, associated with other morbidity categories in 78%. The predictive value of symptoms was lower than 26% for diagnosing broad disease categories. Conclusions These results depict an extremely difficult scenario for dichotomous diagnostic strategies aimed at classifying patients’ symptoms as either organic or functional. Rather than struggling to choose one of these hypotheses, it is suggested that both of them should always be addressed concurrently. PMID:18570008

    Eight elderly patients (average age 76.1±4.3 years) with balanitis xerotica obliterans (BXO) accompanied by phimosis presented with difficulty in urination. Preoperative average international prostate symptom score, average maximum urinary flow rate, and average volume of residual urine were 20.7±6.3 points (n=8), 5.1±3.6 ml/s (n=5), and 85.4±77.3 ml (n=8), respectively. Some of the patient's complaints, such as severe dribbling of urine, urinary stream division, and ballooning of the foreskin, were not included in the items of the major questionnaire on urination. Dorsal incision and circumcision was performed in all patients, and all were pathologically diagnosed with BXO. Meatoplasty was performed in one patient with a meatal stenosis. No coexistence of penile cancer was observed. Statistically significant improvements were observed in subjective and objective findings after treatment. In conclusion, BXO with phimosis in elderly patients should be considered as a cause of lower urinary tract symptoms. PMID:23827865

    Purpose: To objectively assess visual field (VF) defects and retinal cell function in healthy subjects and patients with macular degeneration using a chromatic multifocal pupillometer. Methods: A multifocal chromatic pupillometer (MCP) was used to record pupillary responses (PR) of 17 healthy subjects and 5 Best Vitelliform macular dystrophy patients. Blue and red light stimuli (peak 485nm and 620nm, respectively) were presented at light intensities of 400 and 1000 cd/m2, respectively at 76 different points in a 16.2 degree VF. The PR of patients were compared with their findings on Humphrey's 24-2 perimetry, optical coherence tomography and the PR obtained from healthy subjects. Results: Patients demonstrated reduced percentage of pupillary contraction and slower maximal contraction velocity, more than two standard errors (SE) away from the mean of healthy subjects in response to red light in majority of VF locations. In response to blue light, the percentage of pupillary contraction was lower (by over two SE) compared with normal controls only in central locations. The latency of maximal contraction velocity was shorter in patients compared with healthy subjects in response to both colors. Conclusions: This study demonstrated the advantage of using MCP-based objective VF to assess central scotoma in macular degeneration. Our finding also suggests that chromatic perimetry may differentiate between PR mediated by cones and rods, and can specifically detect defects in macular cones. Different parameters of PR such as latency of maximal contraction velocity may shed light on the pathophysiology of different blinding diseases.

    Atrial fibrillation (AF) is the most common sustained arrhythmia in the World, occurring in approximately 0.4% of the general population. The purpose of the present study was to see the trend of use of warfarin in hospital admitted patients with atrial fibrillation. It was conducted in the department of cardiology, University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2008 to January 2009. A total of 150 patients with atrial fibrillation were enrolled in this study. Out of them, male were 60(40%) and female 90(60%); age range 22-79 years. Most common presenting symptoms were palpitation (80%) & dyspnoea (70%). Chronic rheumatic heart disease (Mitral stenosis) (33%) was found in most cases followed by IHD (22%), hypertension (21%). According to CHADS₂ score, most of the patients belonged to moderate risk group (47%) and 32% in low risk group. Anticoagulation with warfarin was used in 40% cases of valvular AF & 25% patients with non valvular AF. Among non valvular AF, it was prescribed for 38% in high risk group, 34% in moderate risk & 3% in low risk group. The study states that warfarin is underused in both valvular & non valvular AF.

    To characterize prehospital delays in patients presenting with acute ST-elevation myocardial infarction to the emergency department of a tertiary hospital in Asia. A retrospective review of 273 patients with diagnosis of ST-elevation myocardial infarction; symptom to door (S2D) time was described in two ways, time from first onset of symptoms; and time from the onset of the worst episode to presentation at emergency department. The median first onset S2D time was 173 min (interquartile range 80-350 min); and median worst episode S2D time was 131 min (interquartile range 70-261 min). Patients with prehospital delay tended to use their own transport compared with the no delay group (P=0.026, 95% confidence interval=0.02-0.24). There was no difference in S2D times for typical compared with atypical symptoms. A large proportion of patients experienced delay in seeking medical care after the onset of acute coronary symptoms. Self-transport was associated with delay. PMID:21317785

    Studies have shown that early- and adult-onset schizophrenia patients differ in pre-morbid traits, illness presentation, psychopathology, and prognosis. We aimed to compare adult-onset patients (age range 26-55 years) with an adolescent-onset cohort (15-25 years) in demographics, illness presentation and functioning at baseline. Participants were from two territory-wide early intervention services for adolescent-onset (n=671) and adult-onset psychosis patients (n=360) in Hong Kong. The adolescent-onset cohort had their initial psychotic episode from 2001-2003; retrospective data collection was done through systematic case note review. The adult-onset cohort was recruited for a larger interventional study from 2009-2011; information was collected via face-to-face interviews. Adult-onset psychosis was significantly associated with more females, more smokers, more non-local birth, more full-time employment, better functioning, poorer medication adherence, more psychiatric hospitalization and fewer with schizophrenia than adolescent-onset psychosis (mean age: 20.4). The effect sizes were small, except for medication adherence where a robust effect was found. No group difference in DUP was found. The finding that adult-onset patients had better functioning challenges the view that adolescent- and adult-onset psychoses share a similar prognostic trajectory. Implications for adapting intervention processes for adolescent- and adult-onset psychosis are discussed.

    Greater trochanteric pain syndrome (GTPS) is a common complaint. Recently, it has become well recognized that tendinopathy and tears of the gluteus medius (GM) are a cause of recalcitrant GTPS. Nevertheless, the clinical syndrome associated with GM tears is not fully characterized. We characterize the clinical history, findings on physical examination, imaging and intraoperative findings associated with symptomatic GM tears. Forty-five patients (47 hips) who underwent GM repair for the diagnosis of tear were evaluated. Pain was estimated on the visual analog scale (VAS) and hip-specific scores were administered to assess functional status. The imaging modalities were reviewed and intra operative findings were recorded. The average patient age was 54 years (17–76), 93% were females. Symptom onset was commonly insidious (75%) and the average time to diagnosis was 28 months (2–240). The most common pain location was the lateral hip (75%). The average pre-surgery VAS and modified Harris Hip Score were 6.65 (0–10) and 55.5 (12–90), respectively. All patients had pathological findings on magnetic resonance angiogram (MRA) ranging from tendinosis to complete tears of the GM tendon. There was a discrepancy between MRA interpretation by a radiologist and findings during surgery. Hip abductor tears are an under-recognized cause of hip pain and hip symptomatology. In this study, we further characterize the clinical presentation of this entity. The data we present here may facilitate early diagnosis, early orthopedic care and avoid unnecessary prolonged patient sufferings. PMID:27011854

    Background Several clinical studies point to a high prevalence of psychotic symptoms in frontotemporal dementia associated with C9ORF72 mutations, but clinicopathological studies addressing the association between C9ORF72 mutations and delusions are lacking. Method Seventeen patients with pathologically proven frontotemporal lobar degeneration (FTLD) associated with C9ORF72 mutations were identified from Neurodegenerative Disease Brain Bank. Of the 17 cases with C9ORF72 mutation, 4 exhibited well-defined delusions. The clinical history, neurological examination, neuropsychological testing, neuroimaging analysis, and postmortem assessment of the patients with delusions were evaluated and compared with the other cases. Result The content of the delusions was mixed including persecution, infidelity, and grandiosity. All cases showed parkinsonism; voxel-based morphometry analysis showed greater precuneus atrophy in patients with delusions than those without delusions. All 4 had unclassifiable FTLD with TAR DNA-binding protein inclusions, with characteristics of both type A and type B. Three cases had additional τ pathology and another had α-synuclein pathology. Conclusion C9ORF72 carriers with well-defined delusions likely associated with additional pathologies and parietal atrophy in neuroimaging. Patients presenting with middle-aged onset of delusions should be screened for C9ORF72 mutations, especially if family history and parkinsonism are present. PMID:25342578

    Peribiliary cysts are cystic dilatations of peribiliary glands in the liver. They are present in ~50% of cirrhotic patients, but are underrecognized because they are usually asymptomatic and rarely present as obstructive jaundice. A 63-year-old male with hepatitis C cirrhosis, awaiting liver transplantation, had a new finding of intrahepatic dilatation on magnetic resonance imaging. This was initially concerning for cholangiocarcinoma, but was ultimately diagnosed as peribiliary cysts. Peribiliary cysts can imitate cholangiocarcinoma on imaging. Therefore, awareness of this condition is essential because misdiagnosis may lead to inappropriate delay or denial for liver transplantation. The ideal imaging modalities to identify peribiliary cysts are magnetic resonance cholangiography and drip infusion cholangiographic computed tomography, though hepatic dysfunction may limit the usefulness of the latter. Peribiliary cysts should be considered in cirrhotic patients with cholestasis, biliary dilatations and negative biopsy of the biliary system for malignancy. PMID:27511912

    Background Extrapulmonary manifestations of tuberculosis have become increasingly important in the era of HIV/AIDS. Case presentation We describe a case of tuberculosis (TB) dactylitis in a patient with AIDS who originated from the Ivory Coast. The diagnosis was established by direct visualization of acid-fast bacilli on joint fluid and bone biopsy of the proximal phalanx. Imaging of the chest revealed multiple bilateral nodules. Confirmation of the diagnosis was made by isolation of Mycobacterium tuberculosis from sputum and bone cultures. Conclusion Tuberculosis should be considered in patients with unusual soft tissue or skeletal lesions, especially when an immunosuppressive condition is present. Ziehl-Neelsen staining and culture of tissue obtained via surgical biopsy offer the most direct approach to diagnosis. PMID:16269085

    Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of the animal hookworm larvae into the epidermis. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated owing to the patient's pregnancy. Cryotherapy with liquid nitrogen resulted in complete resolution of her lesion and symptoms.

    We developed a multimodal adaptive optics (AO) retinal imager which is the first to combine high performance AO-corrected scanning laser ophthalmoscopy (SLO) and swept source Fourier domain optical coherence tomography (SSOCT) imaging modes in a single compact clinical prototype platform. Such systems are becoming ever more essential to vision research and are expected to prove their clinical value for diagnosis of retinal diseases, including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), and retinitis pigmentosa. The SSOCT channel operates at a wavelength of 1 microm for increased penetration and visualization of the choriocapillaris and choroid, sites of major disease activity for DR and wet AMD. This AO system is designed for use in clinical populations; a dual deformable mirror (DM) configuration allows simultaneous low- and high-order aberration correction over a large range of refractions and ocular media quality. The system also includes a wide field (33 deg.) line scanning ophthalmoscope (LSO) for initial screening, target identification, and global orientation, an integrated retinal tracker (RT) to stabilize the SLO, OCT, and LSO imaging fields in the presence of lateral eye motion, and a high-resolution LCD-based fixation target for presentation of visual cues. The system was tested in human subjects without retinal disease for performance optimization and validation. We were able to resolve and quantify cone photoreceptors across the macula to within approximately 0.5 deg (approximately 100-150 microm) of the fovea, image and delineate ten retinal layers, and penetrate to resolve features deep into the choroid. The prototype presented here is the first of a new class of powerful flexible imaging platforms that will provide clinicians and researchers with high-resolution, high performance adaptive optics imaging to help guide therapies, develop new drugs, and improve patient outcomes.

    Case series Patient: Female, 21 • Female, 29 Final Diagnosis: Anaphylactoid syndrome of pregnancy Symptoms: Coagulation dysfunctional Medication: — Clinical Procedure: Cardiac intensive care Specialty: Obstetrics and Gynecology Objective: Rare disease Background: Anaphylactoid syndrome of pregnancy (ASP) is a rare but extremely serious complication, with an estimated incidence in North America of 1 in 15 200 deliveries. Despite its rarity, ASP is responsible for approximately 10% of all childbirth-associated deaths in the United States. At present, there is no validated biomarker or specific set of risk factors sufficiently predictive of ASP risk to incorporate into clinical practice. Toward the goal of developing a methodology predictive of an impending ASP event for use by obstetricians, anesthesiologists, and other practitioners participating in infant deliveries, physicians encountering an ASP event have been encouraged to report the occurrence of a case and its biologically plausible risk factors. Case Report: Herein, we report on 2 patients who presented with a presumptive diagnosis of ASP to the delivery unit of a community hospital. Patient One was a 21-year-old, obese (5′11″ tall, 250 lbs., BMI 34.9) white female, 1 pregnancy, no live births (G1P0), estimated gestational age (EGA) 40.2 weeks. Patient Two was a 29-year-old, obese (5′7″ tall, 307 lbs., BMI 48.1) Hispanic female, second pregnancy, with 1 previous live birth via C-section (G2P1-0-0-1). Her pregnancy was at gestational age 38 weeks plus 2 days. Conclusions: Patient One had 2 possible risk factors: administration of Pitocin to induce labor and post-coital spotting from recent intercourse. Patient Two suffered premature rupture of the placental membranes. Both Patient One and Patient Two had very high body mass indices (BMIs), at the 97th and 99th percentiles, respectively. In the relatively few cases of anaphylactoid syndrome of pregnancy described to date, this is the first report

    To determine whether patients from disadvantaged socioeconomic groups present with more advanced thyroid carcinoma or experience differing management and clinical outcomes, we retrospectively reviewed the charts of 292 patients seen at MD Anderson Cancer Center and Ben Taub General Hospital between 1987 and 1994. At diagnosis, the mean age was 42 +/- 16 years, 78% of patients were female, 76% of patients were low risk (TNM stage I or II), and 22% high risk (stage III or IV). Neighborhood income (+/- standard error of the mean [SEM]) (1990 census data) was lower in the high-risk group compared with the low-risk group (US dollars 26200 +/- 1670 vs. US dollars 30900 +/- 870, p = 0.012). Men were more likely than women to present at an older age (47.5 +/- 16.7 vs. 40.2 +/- 16.0, p = 0.0014) and in the high-risk group (46% vs. 15%, p < 0.0001). No socioeconomic factor (ethnicity, marital status, occupation prestige, neighborhood income, insurance type) influenced initial diagnostic assessment. Similarly, no socioeconomic factor influenced initial disease management or the type of follow-up received over the 12-year period. Married patients had a lower 5-year recurrence rate than those unmarried (18% vs. 32%, p = 0.03); however, this did not affect overall or disease-specific survival. Similarly, ethnicity, marital status, occupation prestige, and insurance type did not influence overall or disease-specific survival. Although 10-year overall survival rates were lower in patients in the lowest income quartile (57% vs. 70% for upper, p = 0.0024) and in men compared with women (39% vs. 76%, p < 0.0001), gender alone influenced 10-year disease-specific survival (80% for men, 89% for women, p = 0.047). In summary, no socioeconomic factor appears to affect initial treatment or follow-up pattern in patients with differentiated thyroid cancer. Income and gender may affect stage at initial disease presentation and may be risk factors affecting eventual clinical outcomes.

    Background. In the fall of 2014, a North American outbreak of enterovirus D68 resulted in a significant number of pediatric hospital admissions for respiratory illness throughout North America. This study characterized the clinical presentation and risk factors for a severe clinical course in children admitted to British Columbia Children's Hospital during the 2014 outbreak. Methods. Retrospective chart review of patients with confirmed EV-D68 infection admitted to BCCH with respiratory symptoms in the fall of 2014. Past medical history, clinical presentation, management, and course in hospital was collected and analyzed using descriptive statistics. Comparison was made between those that did and did not require ICU admission to identify risk factors. Results. Thirty-four patients were included (median age 7.5 years). Fifty-three percent of children had a prior history of wheeze, 32% had other preexisting medical comorbidities, and 15% were previously healthy. Ten children (29%) were admitted to the pediatric intensive care unit. The presence of complex medical conditions (excluding wheezing) (P = 0.03) and copathogens was associated with PICU admission (P = 0.02). Conclusions. EV-D68 infection resulted in severe, prolonged presentations of asthma-like illness in the hospitalized pediatric population. Patients with a prior history of wheeze and preexisting medical comorbidities appear to be most severely affected, but the virus can also cause wheezing in previously well children. PMID:27610028

    2002-01-01

    In this 8-week open-label, prospective study, 30 patients with grass pollen allergy and ocular itching instilled nedocromil sodium 2% ophthalmic solution twice daily for a 5-day baseline period, followed by once-daily dosing thereafter. Physicians assessed clinical signs after the twice-daily period and after weeks 1 and 3 of the once-daily period; patients rated ocular symptoms daily. Use of specified rescue medication was permitted. Symptom scores for ocular itching, stinging, redness, swelling, burning, tearing, and light sensitivity did not differ significantly between the dosage periods. Scores for erythema, edema, conjunctival injection, and the entire conjunctiva decreased slightly during once-daily administration; discharge scores were unchanged. Of the 20 patients who used rescue medication, only 5 increased their usage by more than two doses per week during the once-daily period. Eighty-three percent of patients were willing to continue the once-daily regimen during the next allergy season. Physicians rated overall control of seasonal allergic conjunctivitis with once-daily administration as "good" or "moderate" in 100% of the patients; 93% of patients applied those ratings themselves. Nedocromil sodium 2% ophthalmic solution instilled once daily maintains control of symptoms in patients who are established on a twice-daily regimen. PMID:12008862

    Hypernatremia is a frequent cause of intensive care unit admission. The patient presented in this article had hypernatremia refractory to D5W (dextrose 5% water) therapy, which led to a complex investigation. Workup revealed central diabetes insipidus most likely secondary to flare up of neurosarcoidosis. The challenge in terms of diagnosis was a presentation with low urine output in the setting of hypernatremia resistant to treatment with desmopressin. This case unfolded the role of hypothyroidism causing secondary renal dysfunction and hence needed continued treatment with thyroxine in addition to treatment for hypernatremia.

    A 45-year-old male with hypertensive end-stage renal disease and on maintenance hemodialysis for 13 years is reported. He presented with life-threatening hematemesis, secondary to esophageal rupture. Immunohistological staining and electron microscopy examination of the esophageal perforation showed depositions of beta 2-microglobulin (beta 2-M) amyoloid. The unique aspect presented here is the localized esophageal involvement with beta 2-M amyloidosis. This is the first reported patient with esophageal perforation, due to the deposition and infiltration of the lower esophagus with beta 2-M which predisposed to its rupture. PMID:9426849

    A 32-year-old man presented with gradually increasing bilateral buttock pain. He had intermittent claudication. Multiple, homogenously enhanced intradural extramedullary lesions at L2-L3 and L5-S1 levels were observed on magnetic resonance imaging. The tumors were debulked and were removed in piecemeal pattern until they had completely been resected. Histopathological examination of the surgical specimens confirmed that both tumors were myxopapillary ependymomas (MPE). MPE presenting as concomitant double tumor at conus-cauda-filum level are very rare. This kind of presentation could not be directly considered as dissemination, since both tumors were in the site of classical origin of MPE. Ten cases of double spinal MPEs have been reported to date. Including the present case, analysis of the 11 patients revealed some facts. There is a male predominance, which is opposite to the ependymomas that are commonly observed in females. Median age at presentation is 15 years. Most pronounced symptom is low back pain that sometimes radiates to lower extremities. Surgical approach was aimed in all tumors, which could be succeeded in all tumors except one. Adjuvant radiation therapy was applied in 5 patients. No recurrences have been reported after surgery or surgery + radiotherapy regimens. PMID:27123029

    A randomized controlled trial was used to evaluate an educational booklet on back pain for patients presenting to five group practices during one calendar year. The booklet had no immediate effect on consultations for back pain, but in the period from two weeks to one year after presentation significantly fewer patients in the group receiving the booklet consulted with back pain (35.6%) than in the control group (42.2%) (P less than 0.05). There were no significant differences between the booklet and control groups in certified absence from work owing to back pain. Referral to hospital, referral to physiotherapy, admissions to hospital and laminectomies were all less common in the booklet group. The reduction in the combined referral rate to physiotherapy and hospital, and the reduction in laminectomy rate almost reached statistical significance at the 5% level. In replying to a questionnaire sent one year after entry to the study 94.1% of respondents in the booklet group said that they had read the book, 84.0% said that they found it useful, and 68.0% said that they still had a copy. Scores on a 15-item test of knowledge about back pain were significantly higher in the group of patients who had received the booklet than in the control group. The results suggest that the booklet had some effect in altering both the knowledge and behaviour of patients with back pain. The provision of an educational booklet was a method of giving information which was appreciated by both patients and doctors.

  20. Survival advantage of partial over radical nephrectomy in patients presenting with localized renal cell carcinoma

    PubMed Central

    2014-01-01

    Background Partial nephrectomy (PN) preserves renal function and has become the standard approach for T1a renal cell carcinoma (RCC). However, there is still an ongoing debate as to which patients will actually derive greater benefit from partial than from radical nephrectomy (RN). The aim of this study was to retrospectively evaluate the impact of the type of surgery on overall survival (OS) in patients with localized RCC. Methods Renal surgery was performed in 4326 patients with localized RCC (pT ≤ 3a N/M0) at six German tertiary care centers from 1980 to 2010: RN in 2955 cases (68.3%), elective (ePN) in 1108 (25.6%), and imperative partial nephrectomy (iPN) in 263 (6.1%) cases. The median follow-up for all patients was 63 months. Kaplan-Meier and Cox regression analyses were carried out to identify prognosticators for OS. Results PN was performed significantly more often than RN in patients presenting with lower tumor stages, higher RCC differentiation, and non-clear cell histology. Accordingly, the calculated 5 (10)-year OS rates were 90.0 (74.6)% for ePN, 83.9 (57.5)% for iPN, and 81.2 (64.7)% for RN (p < 0.001). However, multivariate analysis including age, sex, tumor diameter and differentiation, histological subtype, and the year of surgery showed that ePN compared to RN still qualified as an independent factor for improved OS (HR 0.79, 95% CI 0.66-0.94, p = 0.008). Conclusion Even allowing for the weaknesses of this retrospective analysis, our multicenter study indicates that in patients with localized RCC, PN appears to be associated with better OS than RN irrespective of age or tumor size.

    We have studied stabilographic characteristics and their dynamics in the healthy children (n=30) and the patients suffering from juvenile cerebral palsy (JCP) in the form of spastic diplegia (n=99) after they had undergone the combined rehabilitation treatment with the use of various methods of electrical stimulation. The mean age of the children was 7.0±1.7 years. The patients with JCP included in the main group (n=45) received therapy with the application of electrical stimulation based on the AKorD apparatus while the patients with JCP comprising the group of comparison were treated with the use of the Mioritm 040 apparatus. Vertical stability of the schoolchildren was evaluated using the Stabilan-01-2 hardware system, once in the healthy children and twice (before and after the termination of rehabilitation) in the patients with JCP. A course of the rehabilitative treatment of the patients with JCP included in the main group resulted in a 24.6% and 15.8% reduction (p<0.05) of the statokinesiogram area in the tests with the open and closed eyes respectively. The visual control coefficient increased significantly. The patients of the comparison group experienced a marked reduction of the area of statokinesiogram in the tests with the open eyes (by 15,5% (р<0,05)) while the remaining characteristics of interest remained unaltered. It is concluded that the treatment of the children presenting with juvenile cerebral palsy with the use of the AKorD apparatus for electrical stimulation is more efficient for the maintenance of the vertical posture in comparison with the treatment based on the use of the Mioritm 040 apparatus.

    Recently, the reemergence of vitamin D deficiency in developed countries has been pointed out. Vitamin D deficiency is diagnosed based on the serum 25-hydroxyvitamin D (25OHD) level. However, its normal range is still controversial, making the diagnosis of vitamin D deficiency difficult. Here, we present seven Japanese patients diagnosed with vitamin D deficiency. Three patients complained of leg bowing, and the other four of tetany. The patients with leg bowing were toddlers. Radiographic surveys demonstrated evidence of rickets. Laboratory findings showed decreased levels of serum inorganic phosphorus and increased levels of alkaline phosphatase (ALP) and intact-parathyroid hormone (iPTH). The serum levels of 25OHD were relatively low, ranging from 13 to 15.2 ng/ml. Of the patients with tetany, three were young infants. Laboratory findings showed decreased levels of serum calcium and increased levels of ALP and iPTH. The serum levels of 25OHD were markedly decreased (below 8 ng/ml). Thus, these results indicate that relatively low levels of 25OHD can cause rickets, a symptom of vitamin D deficiency, and that clinicians should therefore carefully evaluate the levels of 25OHD.

    Introduction. We hereby describe the case of a young female patient who presented with pseudothrombotic microangiopathy, as well as pancytopenia accompanied by autoimmune atrophic gastritis. Case Presentation. A 36-year-old Caucasian woman presented to the emergency department with fatigue and dyspnea on minimal exertion. Physical examination was unremarkable except for pallor and noninjected conjunctiva. Laboratory tests revealed high LDH and low hemoglobin, white blood cells, platelets, and haptoglobin. The peripheral blood smear showed schistocytes suggestive of pseudothrombotic microangiopathy. Low cobalamin level and hyperhomocysteinemia were also detected. Autoimmune atrophic gastritis was confirmed by gastric biopsy and positive anti-intrinsic factor antibodies. Vitamin B12 supplements were given which led to rapid recovery and normalization of blood parameters. Conclusion. This case highlights the importance and serves as a reminder to clinicians to rule out cobalamin deficiency and autoimmune atrophic gastritis in patients presenting with a picture suggestive of thrombotic thrombocytopenic purpura and pancytopenia, which was completely reversible after appropriate replacement therapy without recurring to unnecessary and invasive procedures such as plasma exchange.

    Costs are an important component of patients' decision making, but a comparatively underemphasized aspect of formal shared decision making. We hypothesized that decision aids also avoid discussion of costs, despite their being tools designed to facilitate shared decision making about patient-centered outcomes. We sought to define the frequency of cost-related information and identify the common modes of presenting cost and cost-related information in the 290 decision aids catalogued in the Ottawa Hospital Research Institute's Decision Aid Library Inventory (DALI) system. We found that 56% (n = 161) of the decision aids mentioned cost in some way, but only 13% (n = 37) gave a specific price or range of prices. We identified 9 different ways in which cost was mentioned. The most common approach was as a "pro" of one of the treatment options (e.g., "you avoid the cost of medication"). Of the 37 decision aids that gave specific prices or ranges of prices for treatment options, only 2 were about surgery decisions despite the fact that surgery decision aids were the most common. Our findings suggest that presentation of cost information in decision aids is highly variable. Evidence-based guidelines should be developed by the International Patient Decision Aid Standards (IPDAS) Collaboration. PMID:25583552

  10. Understanding missed opportunities for more timely diagnosis of cancer in symptomatic patients after presentation.

    2015-03-31

    The diagnosis of cancer is a complex, multi-step process. In this paper, we highlight factors involved in missed opportunities to diagnose cancer more promptly in symptomatic patients and discuss responsible mechanisms and potential strategies to shorten intervals from presentation to diagnosis. Missed opportunities are instances in which post-hoc judgement indicates that alternative decisions or actions could have led to more timely diagnosis. They can occur in any of the three phases of the diagnostic process (initial diagnostic assessment; diagnostic test performance and interpretation; and diagnostic follow-up and coordination) and can involve patient, doctor/care team, and health-care system factors, often in combination. In this perspective article, we consider epidemiological 'signals' suggestive of missed opportunities and draw on evidence from retrospective case reviews of cancer patient cohorts to summarise factors that contribute to missed opportunities. Multi-disciplinary research targeting such factors is important to shorten diagnostic intervals post presentation. Insights from the fields of organisational and cognitive psychology, human factors science and informatics can be extremely valuable in this emerging research agenda. We provide a conceptual foundation for the development of future interventions to minimise the occurrence of missed opportunities in cancer diagnosis, enriching current approaches that chiefly focus on clinical decision support or on widening access to investigations.

    A rare case of ruptured carotid-ophthalmic aneurysm splitting the optic nerve was reported. A 52-year-old man presented with a sudden severe headache and bilateral visual deterioration. His right visual acuity was hand motion and the left was 2.0. His left visual field revealed a partial defect of the temporal visual field. Three-dimensional CT angiography revealed an ophthalmic aneurysm of 9 mm projecting superior-medially, The operation was performed to preserve the visual function as much as possible. The C2 portion aneurysm splitting the right optic nerve was visible. Before aneurysm clipping, the right anterior clinoid process and optic canal were drilled out to reduce the tension of the optic nerve. Intraoperative monitoring of visual evoked potential (VEP) under propofol anesthesia was performed to prevent further visual disturbance. Electroretinogram (ERG) was introduced to ascertain the arrival of the light stimulus at the retina even when the VEP could not be recorded. The right ERG was recorded, but the right VEP was flat. Both ERG and VEP were reproducible on the left side. Six months after the operation, the right visual acuity had improved to 0.08 and the visual field revealed nasal hemianopsia. The left visual acuity was unchanged while the visual field had improved to upper temporal quadrant hemianopsia. Various attempts to preserve the visual function were discussed.

    Microscope-integrated intraoperative OCT (iOCT) enables imaging of tissue cross-sections concurrent with ophthalmic surgical maneuvers. However, limited acquisition rates and complex three-dimensional visualization methods preclude real-time surgical guidance using iOCT. We present an automated stereo vision surgical instrument tracking system integrated with a prototype iOCT system. We demonstrate, for the first time, automatically tracked video-rate cross-sectional iOCT imaging of instrument-tissue interactions during ophthalmic surgical maneuvers. The iOCT scan-field is automatically centered on the surgical instrument tip, ensuring continuous visualization of instrument positions relative to the underlying tissue over a 2500 mm2 field with sub-millimeter positional resolution and <1° angular resolution. Automated instrument tracking has the added advantage of providing feedback on surgical dynamics during precision tissue manipulations because it makes it possible to use only two cross-sectional iOCT images, aligned parallel and perpendicular to the surgical instrument, which also reduces both system complexity and data throughput requirements. Our current implementation is suitable for anterior segment surgery. Further system modifications are proposed for applications in posterior segment surgery. Finally, the instrument tracking system described is modular and system agnostic, making it compatible with different commercial and research OCT and surgical microscopy systems and surgical instrumentations. These advances address critical barriers to the development of iOCT-guided surgical maneuvers and may also be translatable to applications in microsurgery outside of ophthalmology. PMID:26309764

    Purpose: To examine how tumor characteristics and dose affect cataract development after plaque radiation therapy. Methods and Materials: Three hundred and eighty-four patients were diagnosed with uveal melanoma and treated with palladium-103 ({sup 103}Pd) plaque radiation therapy. Of these, 282 (74%) inclusion met exclusion criteria for follow-up time, tumor location, and phakic status. Then patient-, ophthalmic-, and radiation-specific factors (patient age, diabetes, hypertension, tumor location, tumor dimensions, and lens dose) were examined (by a Cox proportional regression model) as predictors for the development of radiation-related cataract. Results: Radiation cataract developed in 76 (24%) of patients at a mean follow-up of 39.8 months (range, 1-192). Patients with anteriorly located tumors were noted to have a higher incidence of cataract at 43.0% (43 of 100 patients) vs. 18.1% (33 cataracts per 182 patients) for posteriorly located tumors (p <0.0001). However, multivariate Cox proportional modeling showed that increasing patient age at time of treatment (p for trend = 0.0003) and higher lens dose (p for trend = 0.001) were the best predictors (biomarkers) for radiation cataract. Conclusions: Although anterior tumor location, greater tumor height, and increased patient age (at treatment) were associated with significantly greater risk for radiation cataract, dose to lens was the most significant factor.

    The stability of acetylcysteine in an extemporaneously compounded ophthalmic solution was studied. Acetylcysteine 10% ophthalmic solution containing 0.025% disodium edetate and 0.5% chlorobutanol in an artificial tears base was prepared and stored at 2-8 degrees C in clear, 15-mL, low-density polyethylene dropper bottles. At 0, 7, 14, 21, 28, 35, and 60 days, a 1-mL sample was removed from each bottle and analyzed for acetylcysteine concentration by high-performance liquid chromatography. Another set of 10% acetylcysteine solutions containing 0.025%, 0.050%, 0.075%, or 0.10% disodium edetate were prepared, stored at room temperature (23-25 degrees C), and analyzed at 0, 7, 15, 30, 40, and 50 days. In the solutions containing 0.025% disodium edetate, acetylcysteine was stable for 60 days at 2-8 degrees C but for less than 7 days at 23-25 degrees C. In the solutions containing 0.75% and 0.10% disodium edetate, acetylcysteine was stable for 40 and 50 days, respectively, at 23-25 degrees C. Acetylcysteine in a 10% acetylcysteine ophthalmic solution containing 0.025% disodium edetate and 0.5% chlorobutanol in an artificial tears base was stable for 60 days at 2-8 degrees C.

With increasing reliance on electronic communication, incoherent texting or “dystextia,” which is a subset of aphasia that is reflected in text messages, can be a useful tool for symptom recognition and analysis. It can be a red flag for the family and therefore can help in early identification of an acute neurological deficit. It is also useful for providers to reliably analyze the deficit as well as establish a timeline of evolution of symptoms. There have been case reports where dystextia has been the presenting feature of stroke or complicated migraine and in one case of meningioma. We present the case of a teenage patient that in our knowledge is the youngest reported case of dystextia, whose aphasia recorded in a text message assisted with stroke localization. This also adds to the literature of dystextia which so far has only seven other cases reported. PMID:27579197

    The gall bladder is least common intra-abdominal organ to be involved by tuberculosis. It is either part of systemic miliary tuberculosis or abdominal tuberculosis. Isolated gall bladder tuberculosis is even rarer, can presents either as calculus or acalculus cholecystitis. Gall bladder tuberculosis presenting as a localized perforation with a sinus formation into anterior abdominal wall is unreported complication in a non immuno-compromised person. A 48-year old female presented with a gradually increasing swelling in right hypochondrium. Abdominal ultrasound showed superficial collection over right hypochondrium with intraperitoneal extension. Computed tomography showed localized gall bladder perforation with extension to the abdominal wall. Patient underwent emergency exploration and cholecystectomy with excision of sinus tract and drainage of abdominal wall abscess. Histopathological examination showed granulomatous cholecystitis suggestive of tuberculosis of gall bladder with extension into the sinus tract. She had an uneventful recovery and was treated with 6-month antitubercular therapy after surgery. PMID:26236458

    A 62-year-old British man with advanced HIV was established on antiretroviral therapy and treatment for disseminated Mycobacterium avium complex and Cytomegalovirus infections. One month later he re-presented with epigastric pain, an epigastric mass and skin lesions. Abdominal imaging revealed large volume lymphadenopathy, which was not present on previous imaging. Blood cultures yielded Penicillium marneffei, a dimorphic fungus endemic to South-east Asia. The patient had spent several years travelling in Thailand prior to the diagnosis of HIV. Penicilliosis is a common AIDS-defining illness in endemic areas, but remains rare in Europe. In this case, it presented in the context of a rapidly decreasing viral load as an immune reconstitution inflammatory syndrome. The challenges of management in the context of multiple comorbidities and polypharmacy are discussed. PMID:23362074

    The prevalence of mycobacterial infection has increased in recent years, especially in patients immunocompromised due to autoimmune disease, malignancy and AIDS. Mycobacterium kansasii infection most commonly presents as tuberculosis-like pulmonary disease. We report the case of a 38-year-old woman with systemic lupus erythematosus (SLE) who developed cellulitis over the left lower leg and had poor response to antibiotics. Two months before this admission, she had sustained a small wound over the right pretibial area and had noticed erythematous swelling after swimming at the beach. Pathologic examination of biopsied tissue showed acid-fast bacilli, and culture yielded M. kansasii. The cellulitis improved gradually during treatment with antimycobacterial agents for 1 year. This case emphasizes the possibility that cutaneous M. kansasii infection may occur in an immunocompromised patient and that exposure to contaminated water is a possible source. With early diagnosis, the response to an antimycobacterial multidrug regimen is usually satisfactory.

    Snakebite is an important public health challenge. Venomous snake bites cause significant morbidity and mortality if treatment measures, especially antivenom therapy, are delayed. We did a case series of 27 adult patients admitted after snakebite to the medical wards of Gondar University Hospital (GUH) from September 2013 to August 2014. The age range was from 15 to 74 years. The male to female ratio was 8:1. The majority (25) of patients presented after 12 hours of being bitten. Most of the bites occurred on the legs. Hematologic complications, including prolonged bedside whole blood clotting test, bleeding complications and Disseminated Intravascular Coagulation, were the common complications detected. The case fatality rate was 4/27 (14.8%). Availability of affordable snake specific antivenom is recommended. A large population study is needed to address the burden in Ethiopia. PMID:27476228

    Objective: To compare the safety and effectiveness of flexible ureteroscopy (F-URS) with transperitoneal laparoscopic ureterolithotomy (TPLU) in cases of obstructive pyelonephritis secondary to large proximal ureteral stones. Methods: A series of 42 patients presenting with obstructive pyelonephritis due to proximal ureteral stones larger than 1.5 cm were included from April 2006 to February 2015 in this comparative study. After drainage of pyonephrosis and resolution of sepsis, 22 patients treated with TPLU (Group I), and 20 patients were treated with F-URS (Group II). Preoperative patient and stone characteristics, procedure-related parameters and clinical outcomes were assessed for each group. Results: It was seen that both methods were effective in the treatment of large proximal ureteral stones. However TPLU provided a higher stone- free rate (100% vs 80%. p=0.043) and lower retreatment rate. There was no difference between the groups for the operative time and complication rate. On the other hand, patients treated with F-URS had less postoperative pain (p=0.008), a shorter hospital stay (p<0.001) and a faster return to daily activities (p<0.001). Conclusions: The results of our study show that both F-URS and TPLU are safe and effective surgical procedures for treatment of large proximal ureteral stones after controlling obstructive pyelonephritis. However, TPLU has a higher stone-free rate with comparable operating time and complication rate as compared to F-URS. On the other hand F-URS has the advantages of less postoperative pain, shorter hospital stay and faster return to daily activities. PMID:27375691

    Background Traffic accidents are ranked first as the cause of personal injury throughout the world. The high number of traffic accidents yielding injuries and fatalities makes them of great importance to Emergency Departments. Material/Methods Patients admitted to Hacettepe University Faculty of Medicine Adult Emergency Department due to traffic accidents were investigated epidemiologically. Differences between groups were evaluated by Kruskall-Wallis, Mann-Whitney, and Wilcoxon tests. A value of p<0.05 was accepted as statistically significant. Results We included 2003 patients over 16 years of age. The mean age was 39.6±16.1 and 55% were males. Admissions by ambulance and due to motor vehicle accidents were the most common. In 2004 the rate of traffic accidents (15.3%) was higher than the other years, the most common month was May (10.8%), and the most common time period was 6 pm to 12 am (midnight). About half of the patients (51.5%) were admitted in the first 30 minutes. Life-threatening condition was present in 9.6% of the patients. Head trauma was the most common type of trauma, with the rate of 18.3%. Mortality rate was 81.8%. The average length of hospital stay was 403 minutes (6.7 hours) and the average cost per patient was 983±4364 TL. Conclusions Further studies are needed to compare the cost found in this study with the mean cost for Turkey. However, the most important step to reduce the direct and indirect costs due to traffic accidents is the prevention of these accidents. PMID:24316815

    The aim of this study was to determine whether a patient educator presentation (PEP) on pemphigus vulgaris would increase second-year dental students' awareness of the importance of learning about rare conditions and improve their retention of rare disease knowledge. The study involved students' subjective assessments of a PEP experience at two U.S. dental schools. In this mixed methods study, cross-sectional data were obtained by surveys and in-depth interviews. Questions focused on students' assessment of the messages acquired from the PEP and its likely impact on their future clinical care. At University 1, students completed paper surveys with open-ended questions and participated in a focus group. At University 2, students completed an online survey consisting of rating scale and open-ended questions. Responses to open-ended questions were categorized into themes. At University 1, 79 students (out of a possible 102; response rate 77.5%) completed the survey, and an additional ten students participated in a focus group. At University 2, 30 students (out of a possible 104; response rate 28.8%) completed the survey. At Universities 1 and 2, 88% and 100%, respectively, of respondents stated the PEP would influence their future clinical decision making. The vast majority of respondents (94% and 100% at University 1 and University 2, respectively) were of the opinion that the personal testimonial from a patient would help them recall information about pemphigus vulgaris in five years' time. Respondents from both universities commented that the PEP emphasized the importance of not dismissing a patient's concerns. These results suggest that a presentation by a patient with a rare condition can be an effective educational tool for preclinical dental students. PMID:27139204

    Introduction. Spontaneous Escherichia coli meningitis is an infrequent condition in adults and is associated with some predisposing factors, including severe Strongyloides stercoralis (SS) infections. Case Presentation. A 43-year-old Hispanic man, with history of travelling to the jungle regions of Peru and Brazil two decades ago, and who received prednisone due to Bell's palsy for three weeks before admission, presented to the Emergency Department with diarrhea, fever, and hematochezia. A week after admission he developed drowsiness, meningeal signs, abdominal distension, and constipation. A cerebrospinal fluid culture showed extended spectrum β-lactamase producing E. coli. A colonoscopy was performed and showed pancolitis. Three days after the procedure the patient became unstable and developed peritoneal signs. He underwent a laparotomy, which ended up in a total colectomy and partial proctectomy due to toxic megacolon. Three days later the patient died in the intensive care unit due to septic shock. Autopsy was performed and microscopic examination revealed the presence of multiple Strongyloides larvae throughout the body. Conclusion. Strongyloides stercoralis infection should be excluded in adults with spontaneous E. coli meningitis, especially, if gastrointestinal symptoms and history of travelling to an endemic area are present. Even with a proper diagnosis and management, disseminated strongyloidiasis has a poor prognosis. PMID:24324900

    Background Cystic fibrosis (CF) is an autosomal recessive disorder with several clinical presentations. This study was undertaken in the Azeri Turkish population in Iran, to investigate gender differences in the age at onset and diagnosis, age of death, and duration of illness of CF. Methods The data of 331 CF patients from 2001 to 2015 was surveyed. Parameters including age, sex, ΔF508 mutation, age at onset, age at diagnosis, age of death and clinical presentations were evaluated for both sexes, using descriptive analysis. The association of gender with these variables was studied using logistic regression, chi-square test and Mann-Whitney U test by SPSS version 18. Odds ratio with a confidence interval of 95% and p≤0.05 was considered statistically significant. Results The study included 191 males (57.7%) and 140 females (42.3%), all showing statistically significant difference (p<0.001). Age duration differed between genders. Male and female patients were further under 9 and 4 years, respectively. The occurrence of ΔF508 mutation was 0.51 times more in females than in males. Age, diagnosis and sex were closely associated: males were diagnosed at a significantly later age than females (p=0.05). While this compression performed based on clinical presentations, males with respiratory disease had a later median age at diagnosis than females at lifespan (p=0.001). The risk of infertility in males was approximately two times greater than in females (p=0.02). Conclusion These findings indicate gender differences in CF patients. Future studies are needed to establish other differences and evaluate the causes for the gender variations.

    A previously healthy patient was seen in the Emergency Department for evaluation of a one-month history of cough and one-day history of hemoptysis. A computed tomography scan of the thorax found a mass on the right lower pulmonary lobe and a mass on the left upper lobe. A biopsy specimen of the right lobe lung mass, obtained during bronchoscopy, demonstrated papilloma. This case report, from a pulmonologist’s perspective, includes a comprehensive review of the patient’s clinical presentation and outcome, as well as a discussion of recurrent respiratory papillomatosis.

    Bacillary angiomatosis is a rare opportunistic infection caused by the gram-negative bacteria Bartonella. The infection is strongly related to human immunodeficiency virus (HIV) infection, and hence, the diagnosis is usually considered based on the fact that the patient is HIV positive. We report on a case of bacillary angiomatosis presenting as a pyogenic granuloma of the hand in an otherwise apparently healthy man. The report is aimed to increase the awareness of hand surgeons that this serious disease may be the first clinical manifestation of HIV infection. The case also demonstrates that once the correct diagnosis is made, medical treatment alone may be sufficient to cure massive recurrent lesions.

    The objective of this study was to elucidate changes in tone sigma (σ) before and after the treatment of the patients with mutational falsetto (n=10) and functional dysphonia (n=10). The control group was comprised of 30 healthy subjects. A personal computer was used to determine the values of SF0 (the mean frequency of the basic speech tone) and sigma (the standard deviation of the frequency values comprising SF0). It was shown that the treatment of the patients presenting with mutational falsetto (MF) and functional dysphonia (FD) resulted in identical quantitative changes of SF0, namely its lowering after the treatment compared with the elevated level before it. At the same time, the measurement of sigma revealed the qualitative difference between these characteristics. Specifically, sigma decreased in the patients with MF and increased in FD. It is concluded that variability in the constituent frequencies of SF0, besides its quantitative changes, should be taken into consideration, when estimating the results of the correction of functional voice disorders.

  12. An absent ophthalmic artery or carotid siphon signal on transcranial Doppler confirms the presence of severe ipsilateral internal carotid artery disease.

    Transcranial Doppler ultrasound provides a useful adjunct to extracranial ultrasound in the diagnosis of carotid bifurcation disease. Previous studies have shown that collateral flow patterns and diminished flow velocities in the ipsilateral middle cerebral artery correlate with hemodynamically significant carotid disease. In a series of 7,054 carotid duplex and transcranial Doppler examinations, 12.5% (95% confidence interval [CI]: 8.7, 16.4) of 287 ophthalmic arteries ipsilateral to an apparent carotid occlusion had no detectable flow signal, compared with 0.5% (95% CI: 0.3, 0.7) of 6,767 ophthalmic arteries ipsilateral to a non-occluded carotid artery (p < 0.001). Carotid siphon signals were not detectable in 24.4% (95% CI: 19.4, 29.4) of arteries ipsilateral to the carotid occlusion, versus 1.0% (95% CI: 0.8, 1.3) ipsilateral to nonoccluded carotid arteries (p < 0.001). A significant number of absent ophthalmic artery and carotid siphon signals (5.7 and 8.7%, respectively) were also found in patients with 80 to 99% extracranial carotid stenosis. A subset of 216 studies with angiographic correlation confirmed the high association of these transcranial Doppler findings with severe stenosis or occlusion of the internal carotid artery. Primary ophthalmological disease or siphon occlusion did not explain these findings. An absent ophthalmic artery or carotid siphon signal on transcranial Doppler examination is believed to represent a failure to detect slow flow distal to severe carotid bifurcation lesions. As a sign of ipsilateral carotid occlusion, the sensitivities of absent ophthalmic artery and carotid siphon signals are quite low (12.5 and 24.4%, respectively). The high specificities of 99.5 and 99.0%, however, make these findings useful in confirming the diagnosis of presumptive carotid occlusion by carotid duplex ultrasound.

    Since its original description in 1913, fewer than 100 lingual osseous choristomas have been reported in the literature; thus, prevalence is unknown. We describe a case of an 11 year old male who was seen in consultation after an incidental left posterior tongue mass was discovered on exam. The patient's presentation of an asymptomatic, hard, pedunculate posterior tongue lesion is typical; however, if one is to believe the proposed congenital remnant theory in regards to the etiology of this benign tumor, it is curious that no mention was made of a lesion of the tongue on prior evaluations by his pediatrician or on the otolaryngologic examinations performed 3 and 6 years prior to the most recent presentation. Included with the case description are interesting radiographs, intra-operative photos, gross specimen photo and microscopic images. PMID:26545466

    Electron beam computed tomography (EBCT) is a unique, noninvasive radiologic method capable of high-resolution imaging that is being increasingly used for evaluation of the cardiovascular system. Among its multiple applications, coronary artery calcium (CAC) imaging has attracted considerable attention because of the potential of this technique for early detection of coronary artery disease (CAD), the leading cause of mortality in our society. Although measurement of CAC has been primarily performed in the outpatient setting in both symptomatic and asymptomatic subjects, several studies have assessed the utility of the method to identify CAD in patients presenting to the emergency department with chest pain suggestive of myocardial ischemia but without objective evidence of the latter. This group comprises a majority of those presenting to the emergency department with chest pain, and their safe, accurate and cost-effective evaluation has been a continuing challenge. PMID:18340176

    A 40-year-old man with AIDS presented with symptoms of a chronic cough, subacute headache, generalised weakness with falls, urinary and faecal incontinence, and acute onset subcutaneous nodules. A chest CT scan showed multiple cavitary and nodular pulmonary infiltrates. MRI of his brain and spinal cord revealed innumerable ring-enhancing lesions. Pathological examination of the purulent material obtained from his subcutaneous lesions, as well as transbronchial tissue specimens obtained by biopsy, revealed beaded and branching Gram-positive rods, subsequently identified by 16S RNA sequencing to be Nocardia abscessus species. We observed an excellent therapeutic response to a combination antimicrobial therapy with resolution of the subcutaneous, pulmonary and central nervous system (CNS) lesions. Infections caused by N. abscessus are rare and typically occur in immunocompromised patients. In this article, we will review the presentation, diagnosis and treatment of N. abscessus infection.

    Wilson's disease typically presents symptoms associated with liver damage or neuropsychiatric disturbances, while endocrinologic abnormalities are rare. We report an unprecedented case of hypopituitarism in a patient with Wilson's disease. A 40-year-old woman presented with depression, general weakness and anorexia. Laboratory tests and imaging studies were compatible with liver cirrhosis due to Wilson's disease. Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism. Brain MRI showed T2 hyperintense signals in both basal ganglia and midbrain but the pituitary imaging was normal. She is currently receiving chelation therapy along with thyroid hormone and steroid replacement. There may be a relationship between Wilson's disease and hypopituitarism. Copper deposition or secondary neuronal damage in the pituitary may be a possible explanation for this theory. PMID:27478349
