    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. PMID:27433041

    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.

    Background This study set out to determine the incidence, socio-demographic, and clinical correlates of Traditional Eye Medicine (TEM) use in a population of newly presenting ophthalmic outpatients attending a tertiary eye care centre in south-eastern Nigeria. Methods In a comparative cross-sectional survey at the eye clinic of the University of Nigeria Teaching Hospital (UNTH), Enugu, between August 2004 - July 2006, all newly presenting ophthalmic outpatients were recruited. Participants' socio-demographic and clinical data and profile of TEM use were obtained from history and examination of each participant and entered into a pretested questionnaire and proforma. Participants were subsequently categorized into TEM- users and non-users; intra-group analysis yielded proportions, frequencies, and percentages while chi-square test was used for inter-group comparisons at P = 0.01, df = 1. Results Of the 2,542 (males, 48.1%; females, 51.9%) participants, 149 (5.9%) (males, 45%; females, 55%) used TEM for their current eye disease. The TEMs used were chemical substances (57.7%), plant products (37.7%), and animal products (4.7%). They were more often prescribed by non-traditional (66.4%) than traditional (36.9%) medicine practitioners. TEMs were used on account of vision loss (58.5%), ocular itching (25.4%) and eye discharge (3.8%). Reported efficacy from previous users (67.1%) and belief in potency (28.2%) were the main reasons for using TEM. Civil servants (20.1%), farmers (17.7%), and traders (14.1%) were the leading users of TEM. TEM use was significantly associated with younger age (p < 0.01), being married (p < 0.01), rural residence (p < 0.01), ocular anterior segment disease (p < 0.01), delayed presentation (p < 0.01), low presenting visual acuity (p < 0.01), and co-morbid chronic medical disease (p < 0.01), but not with gender (p = 0.157), and educational status (p = 0.115). Conclusion The incidence of TEM use among new ophthalmic outpatients at UNTH is low

    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

    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.

    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

    Context: Screening for ocular manifestations of leukemia, although not a routine practice, is important as they may antedate systemic disease or form an isolated focus of its relapse. Aims: This study evaluates the spectrum of ocular manifestations in acute and chronic leukemias presenting to a tertiary care center in India. Settings and Design: Subjects of leukemia presenting to a tertiary care center in India. Subjects and Methods: A prospective, cross-sectional study looking at the spectrum of ocular manifestations in all inpatients of acute or chronic leukemia. Statistical Analysis Used: The collected data were analyzed using the Statistical Package for Social Sciences for Windows software, version 16 (SPSS Inc., Chicago, Illinois, USA). Results: The study subjects (n = 96) comprised 61 males and 35 females whose age ranged from 18 months to 91 years (mean = 39.73, ±22.1). There were 79 adults and 17 children, 53 new and 43 existing patients, 68 acute and 28 chronic, 61 myeloid and 35 lymphoid patients. Ocular lesions were found in 42 patients (43.8%). The ocular manifestations of leukemia were significantly (P = 0.01467) more frequent in acute 35/68 (51.9%) than chronic 7/28 (25%) leukemias. Primary or direct leukemic infiltration was seen in 8 (8.3%) subjects while secondary or indirect involvement due to anemia, thrombocytopenia, hyperviscosity, total body irradiation, and immunosuppression were seen in 42 (43.8%) subjects. Ocular changes were present in 37/79 (46.8%) adults and 5/17 (29.4%) children (P = 0.09460). Twenty-eight males (28/61) 45.9% and 14/35 (40%) females had ocular manifestations (P = 0.2874). The ocular manifestations were significantly (P = 0.01158) more frequent in myeloid leukemias 32/61 (52.9%) than lymphoid leukemias 10/35 (28.6%). Conclusions: Leukemic ophthalmic lesions were found in 42/96 (43.8%) patients. Ocular involvement is more often seen in adults, acute and myeloid leukemias. All the primary leukemic manifestations were seen

    Objective Spontaneous preterm deliveries (PTDs) have been consistently associated with maternal vascular complications. We aimed to investigate an association between PTD and subsequent maternal ophthalmic morbidity. Study Design In this population-based cohort study, we included all singleton deliveries occurring between 1988 and 2013. We excluded women with known ophthalmic disease. The exposure was at least one pregnancy with PTD. Outcomes included different maternal ophthalmic morbidity. The cumulative incidence and adjusted hazard ratios were assessed using a Kaplan-Meier survival curve and Cox hazards models. Results Of the 105,018 patients included, 17,600 (16.7%) delivered preterm. Patients with a history of PTD (both induced and spontaneous) had higher rates of ophthalmic complications (odds ratio [OR]: 2.12; confidence interval [CI]: 1.6-2.7; p < 0.001), specifically diabetic retinopathy and glaucoma (OR: 4.79 and 2.48, respectively). A linear association was found between the number of previous PTDs and ophthalmic complications (0.2% for no PTD; 0.4% for one PTD; 0.6% for two or more PTDs; p < 0.001) and for early and late PTD (p < 0.001). A Cox model revealed an independent association between PTD and ophthalmic complications (adjusted hazard ratio: 2.2; 95% CI: 1.6-2.9). Conclusion A history of PTD is an independent risk factor for ophthalmic morbidity. PMID:26874352

    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

    A pulmonary embolus (PE) is a blockage of the pulmonary artery caused by the formation of a clot. Fifteen percent of patients who develop a pulmonary embolus may die. What is the likelihood that the surgical ophthalmic patient will develop a pulmonary embolus during surgery? The risk is high, especially for patients with a multiplicity of health concerns, such as heart disease, diabetes, ischemia and obesity. Prophylactic measures are the key to managing the embolytic patient. The application of sequential compression devices (SCDs) is effective in preventing deep vein thrombosis (DVT), venous thromboembolism (VTE) and pulmonary embolus (PE). There has been controversy over whether it is necessary to use SCDs as prophylaxes to prevent a pulmonary embolus (PE) in the ophthalmic surgical patient. The patients who are at greatest risk are those who have procedures lasting 30 minutes or more and those who have a multiplicity of health concerns. In the ophthalmic world, little consideration has been given to using SCDs. The question is, "What would be the likelihood that an ophthalmic patient develop a pulmonary embolus (PE) during surgery?" The answer would be "high," especially in patients with medical histories with poor prognoses. PMID:19708429

    We report a patient with branch retinal vein occlusion (BRVO) accompanied by superior ophthalmic vein (SOV) thrombosis resulting from severe SOV enlargement in a patient with Graves ophthalmopathy (GO). A 78-year-old woman diagnosed with BRVO presented with reduced vision. She had a more than 20-year history of unilateral GO. Fluorescein angiography and spectralis optical coherence tomography revealed BRVO with cystoid macular edema. Approximately 5 months later, she complained of advanced left proptosis. A computed tomography scan at that time revealed dilated SOV with high internal attenuation due to SOV thrombosis of the left orbit. Because of the uncertain onset of SOV thrombosis and minimal signs of acute orbital congestion, we prescribed prophylactic daily aspirin to improve blood flow rather than a heparin-based treatment. In addition, she was treated with lubricants for exposure keratopathy and a dorzolamide/timolol eyedrops to prevent increases in intraocular pressure. This is the first clinical report of BRVO accompanied by SOV thrombosis due to SOV enlargement in chronic severe GO. It should be recognized that SOV thrombosis can lead to an increase in proptosis even in chronic GO. PMID:24978681

    Reflex lid closure often protects the eyes during facial burns. Although corneal burns are uncommon, other ophthalmic injuries occur more frequently. Ophthalmic burns are usually associated with marked facial damage and possible inhalation injury. Failure to recognize and appropriately treat ophthalmic burns can lead to catastrophic sequelae. We performed a 2-year survey of all facial burns in our burn unit. Forty-four patients with thermal facial burns were identified. Sixteen patients had ophthalmic injuries. Corneal injury was detected in 13 per cent (2/16). Intubation was required in 43.75 per cent (7/16) of patients with ophthalmic injuries. Mortality was 25 per cent (4/16). We conclude that patients with facial burns severe enough to cause ophthalmic injuries may be associated with other lethal injuries, and a high index of suspicion should be maintained until all lethal injuries are ruled out. All ophthalmic injuries should be evaluated by an ophthalmologist. PMID:8651533

    Ophthalmic nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used by clinicians to manage ocular inflammation and pain following cataract surgery. Over the past decade, the US Food and Drug Administration has approved multiple topical NSAIDs for these purposes, including several reformulated products. One of these medications, bromfenac ophthalmic solution, has a long and extensive history, with proven efficacy and safety in patients following cataract surgery. The evolution of bromfenac ophthalmic solution over the years has involved either lowering the concentration of the active ingredient or extending the dosing interval to improve patient adherence/compliance. This review will focus on the history and progression of bromfenac ophthalmic solution and report the available patient preference and adherence data regarding this ocular NSAID throughout its evolution.

    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

  2. Hypothalamic stimulation for trigeminal neuralgia in multiple sclerosis patients: efficacy on the paroxysmal ophthalmic pain.

    Trigeminal neuralgia is a disorder characterized by paroxysmal pain arising in one or more trigeminal branches; it is commonly reported in multiple sclerosis. In multiple sclerosis patients the ophthalmic branch may be frequently involved and the risks carried by neurosurgical ablative procedures are higher including major adverse effects such as corneal reflex impairment and keratitis. The objective of this works is to assess the role of posterior hypothalamus neuromodulation in the treatment of trigeminal neuralgia in multiple sclerosis patients. Five multiple sclerosis patients suffering from refractory recurrent trigeminal neuralgia involving all three trigeminal branches underwent deep brain stimulation of the posterior hypothalamus. The rationale of this intervention emerges from our earlier success in treating pain patients suffering from trigeminal autonomic cephalalgias. After follow-up periods that ranged from 1 to 4 years after treatment, the paroxysmal pain arising from the first trigeminal branch was controlled, whereas the recurrence of pain in the second and third trigeminal branches necessitated repeated thermorhizotomies to control in pain in two patients after 2 years of follow-up. In conclusion, deep brain stimulation may be considered as an adjunctive procedure for treating refractory paroxysmal pain within the first trigeminal division so as to avoid the complication of corneal reflex impairment that is known to follow ablative procedures.

    Purpose To report on the influence of ophthalmic artery chemosurgery (OAC) on enucleation rates, ocular and patient survival from metastasis and impact on practice patterns at Memorial Sloan Kettering for children with advanced intraocular unilateral retinoblastoma. Patients and Methods Single-center retrospective review of all unilateral retinoblastoma patients with advanced intraocular retinoblastoma treated at MSKCC between our introduction of OAC (May 2006) and December 2014. End points were ocular survival, patient survival from metastases and enucleation rates. Results 156 eyes of 156 retinoblastoma patients were included. Primary enucleation rates have progressively decreased from a rate of >95% before OAC to 66.7% in the first year of OAC use to the present rate of 7.4%. The percent of patients receiving OAC has progressively increased from 33.3% in 2006 to 92.6% in 2014. Overall, ocular survival was significantly better in eyes treated with OAC in the years 2010–2014 compared to 2006–2009 (p = 0.023, 92.7% vs 68.0% ocular survival at 48 months). There have been no metastatic deaths in the OAC group but two patients treated with primary enucleation have died of metastatic disease. Conclusion OAC was introduced in 2006 and its impact on patient management is profound. Enucleation rates have decreased from over 95% to less than 10%. Our ocular survival rate has also significantly and progressively improved since May 2006. Despite treating more advanced eyes rather then enucleating them patient survival has not been compromised (there have been no metastatic deaths in the OAC group). In our institution, enucleation is no longer the most common treatment for advanced unilateral retinoblastoma. PMID:26709699

    AIM To determine the safety of prophylactic intracameral moxifloxacin after cataract surgery in patients with penetrating keratoplasty (PKP). METHODS In this retrospective study of consecutive patients who had phacoemulsification cataract surgery after PKP, were treated with intracameral moxifloxacin 0.5% ophthalmic solution (0.5 mg/0.1 mL). The main outcome measures were anterior chamber reaction, best corrected visual acuity (BCVA), corneal endothelial cell count (ECC), and central corneal thickness (CCT). RESULTS Fifty-five patients were recruited (26 males, 29 females). The mean age was 54.36±4.97y (range 45-64y). All eyes had improved postoperative BCVA. The mean BCVA was 0.25 preoperatively and 0.57 postoperatively, which was statistically significant (P<0.001). One eye had 3+, 7 eyes had 2+, 12 eyes had 1+ and 8 eyes had trace amount of aqueous cells on the first day after surgery. All eyes had no anterior chamber cells at subsequent follow up examinations. Effective phacoemulsification time was 4.33±1.01s. The mean ECC was 2340.20 cells/mm2 preoperatively and 1948.75 cells/mm2 1mo postoperatively (P<0.001). The increase of 21.09 µm in postoperative pachymetry 1mo after surgery was statistically significant (P<0.001). CONCLUSION No untoward effects were observed after intracameral injection of moxifloxacin (0.5 mg/0.1 mL) in terms of anterior chamber reaction, CCT, ECC, and visual rehabilitation at the conclusion of cataract surgery in patients with PKP.

  5. A pilot study for development of a novel tool for clinical decision making to identify fallers among ophthalmic patients

    PubMed Central

    2015-01-01

    Background Falls in the elderly is a major problem. Although falls have a multifactorial etiology, a commonly cited cause of falls in older people is poor vision. This study proposes a method to discriminate fallers and non-fallers among ophthalmic patients, based on data-mining algorithms applied to health and socio-demographic information. Methods A group of 150 subjects aged 55 years and older, recruited at the Eye Clinic of the Second University of Naples, underwent a baseline ophthalmic examination and a standardized questionnaire, including lifestyles, general health, social engagement and eyesight problems. A subject who reported at least one fall within one year was considered as faller, otherwise as non-faller. Different tree-based data-mining algorithms (i.e., C4.5, Adaboost and Random Forest) were used to develop automatic classifiers and their performances were evaluated by assessing the receiver-operator characteristics curve estimated with the 10-fold-crossvalidation approach. Results The best predictive model, based on Random Forest, enabled to identify fallers with a sensitivity and specificity rate of 72.6% and 77.9%, respectively. The most informative variables were: intraocular pressure, best corrected visual acuity and the answers to the total difficulty score of the Activities of Daily Vision Scale (a questionnaire for the measurement of visual disability). Conclusions The current study confirmed that some ophthalmic features (i.e. cataract surgery, lower intraocular pressure values) could be associated with a lower fall risk among visually impaired subjects. Finally, automatic analysis of a combination of visual function parameters (either self-evaluated either by ophthalmological tests) and other health information, by data-mining algorithms, could be a feasible tool for identifying fallers among ophthalmic patients.

    2015-01-01

    Postherpetic neuralgia (PHN) is a common and exceptionally drug-resistant neuropathic pain condition. In this cross-sectional skin biopsy study, seeking information on the responsible pathophysiological mechanisms we assessed how ophthalmic PHN affects sensory and autonomic skin innervation. We took 2-mm supraorbital punch skin biopsies from the affected and unaffected sides in 10 patients with ophthalmic PHN. Using indirect immunofluorescence and a large panel of antibodies including protein gene product (PGP) 9.5 we quantified epidermal unmyelinated, dermal myelinated and autonomic nerve fibers. Although skin biopsy showed reduced epidermal and dermal myelinated fiber density in specimens from the affected side, the epidermal/dermal myelinated nerve fiber ratio was lower in the affected than in the unaffected side (p < 0.001), thus suggesting a predominant epidermal unmyelinated nerve fiber loss. Conversely, autonomic skin innervation was spared. Our study showing that ophthalmic PHN predominantly affects unmyelinated nerve fiber and spares autonomic nerve fiber might help to understand the pathophysiological mechanisms underlying this difficult-to-treat condition.

    2015-01-01

    Purpose: A retrospective study aimed to evaluate high risk cases where conventional Extracapsular cataract extraction (ECCE) was performed, their intra-operative and post-operative outcomes. Setting: Sri Srinivasa Sankara Nethralaya (Tirupati) Tirumala Tirupati Devastanams Central Hospital, Tirupati, India. Subjects and Methods: Retrospective study of 207 patients who underwent ECCE at the hospital between august 2010 to June 2012. Operative data included details like grade of risk, intra and postoperative complications and visual outcome. Results: Out of 207 cases, 188 were in group 3 (moderate risk, 3-5 points) and 19 in group 4 (high risk, 6 points or more). The intra operative complications in group 3 were 8 (0.042%) and none in group 4. Final best corrected visual acuity (BCVA) of 6/12 and more were 184 (88.88%). Final refraction of less than 2.0 astigmatism was seen in 80.19% (n=166). Conclusion: Segregation of cases depending on the risk factors can lead to lower intra operative complications and therefore good postoperative outcome. We believe that phacoemulsification, manual small incision cataract surgery (MSICS) and ECCE each has its own importance and should be used as per the cataract with risk factors. PMID:26903724

  20. Risk of Hemorrhage during Needle-Based Ophthalmic Regional Anesthesia in Patients Taking Antithrombotics: A Systematic Review

    PubMed Central

    Takaschima, Augusto; Marchioro, Patricia; Sakae, Thiago M.; Porporatti, André L.; Mezzomo, Luis André; De Luca Canto, Graziela

    2016-01-01

    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.

    2016-01-01

    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

    Aims To compare the efficacy and safety of 3% diquafosol ophthalmic solution with those of 0.1% sodium hyaluronate ophthalmic solution in dry eye patients, using mean changes in fluorescein and rose bengal staining scores as endpoints. Trial design and methods In this multicenter, randomised, double-masked, parallel study of 286 dry eye patients with fluorescein and rose bengal staining scores of ≥3 were randomised to the treatment groups in a 1 : 1 ratio. Efficacy and safety were evaluated after drop-wise instillation of the study drug, six times daily for 4 weeks. Results After 4 weeks, the intergroup difference in the mean change from baseline in fluorescein staining score was −0.03; this verified the non-inferiority of diquafosol. The mean change from baseline in rose bengal staining score was significantly lower in the diquafosol group (p=0.010), thus verifying its superiority. The incidence of adverse events was 26.4% and 18.9% in the diquafosol and sodium hyaluronate groups, respectively, with no significant difference. Conclusions Diquafosol (3%) and sodium hyaluronate (0.1%) exhibit similar efficacy in improving fluorescein staining scores of dry eye patients, whereas, diquafosol exhibits superior efficacy in improving rose bengal staining scores. Diquafosol has high clinical efficacy and is well tolerated with a good safety profile. PMID:22914501

    2015-01-01

    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.

    The present review is concerned with some essential formulative and therapeutic aspects of semisolid ophthalmic vehicles. The history and the most recent developments of the traditional lipophilic vehicles (ointments) are first outlined. The hydrophilic vehicles (hydrogels) based on synthetic polymers (polyacrylates, PEG, PVA, Pluronics, etc.), semisynthetic polymers (cellulose derivatives) and natural polymers (hyaluronic and polygalacturonic acid, alginates, etc.) are then examined. Some recent formulations of particular type are finally described. PMID:2699716

    2012-01-01

    Purpose To establish whether hypothalmic-pituitary-adrenal axis suppression is possible secondary to long-term topical ophthalmic corticosteroid use in patients who have undergone penetrating keratoplasty (PKP). Methods Patients who had undergone a PKP and had been using corticosteroid-based eye drops continuously for more than 6 months, with no history of concomitant steroid (oral, inhaled, or cutaneous) use, were included within the study. A low-dose short Synacthen (LDSST) test was performed in each patient followed later by a short Synacthen test (SST). The mean SST and LDSST after 30 min were calculated along with their corresponding 95% confidence intervals (CIs). Correlation between both baseline SST and baseline LDSST with duration of treatment was determined using Spearman's correlation. Results In all, 20 patients were included within the study. The mean duration treatment was 28.2 months (range 11–96 months). All patients had normal baseline cortisol levels in both SST and LDSST tests. The mean 30 min SST was 753.8 nmol/l (95%CI: 696.6 nmol/l, 811.0 nmol/l) and no patients displayed inadequate adrenal response. The mean 30 min LDSST was 709.8 nmol/l (95%CI: 665.1 nmol/l, 754.5 nmol/l) and only one patient had an inadequate adrenal response. There was no correlation between baseline SST or LDSST and duration of treatment. Conclusions This study found no evidence that patients using continuous long-term corticosteroid eye drops after PKP experienced inadequate adrenal response. We did not find any evidence of a negative correlation between length of treatment and SST or LDSST measurements at baseline. PMID:22344184

    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

    The present report describes the clinical course and treatment of a Mooren-like ulcer associated with abuse of topical anesthetics and dexamethasone. A 38-year-old male physician treated himself with lidocaine, tetracaine and dexamethasone (DEX) eye drops for severe pain and decline of vision in both eyes. After six months of treatment, his right cornea exhibited annular melting with full-thickness stromal infiltration at the limbus and central corneal haze. His left cornea was completely melted and exhibited iris prolapse. The patient was treated with topical antibiotics, lubricants and underwent a binocular keratoplasty. The surgery was successful and after eight months the postoperative best-corrected visual acuities were counting fingers in the right eye and light perception in the left eye. In summary, this report documents a severe case of keratopathy presenting as Mooren-like ulcer caused by topical anesthetics and DEX, which were treated via keratoplasty, resulting in useful vision being retained.

    2015-01-01

    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. Ultrasound-guided eye blocks afford real-time visualization of needle position and local

    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. PMID:23566559

    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

    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

    Timolol maleate is a non-selective beta-adrenoceptor antagonist currently used mainly as an ocular preparation for the treatment of glaucoma and ocular hypertension. Despite the topical administration, ophthalmic timolol causes systemic adrenergic beta-blocking because of absorption from the eye into the systemic circulation. Gel formulations of ophthalmic timolol have been developed to reduce systemic absorption and adverse effects in comparison with conventional aqueous solution formulations. Timolol is metabolized by the polymorphic cytochrome P450 2D6 enzyme (CYP2D6). The changes in heart rate (HR) are the most striking effects of the systematically absorbed fraction of ophthalmic timolol, with 0.5 % aqueous formulations presenting larger effects than 0.1 % hydrogel formulations, especially during exercise. Plasma levels of ophthalmic timolol correlate with the changes in HR. Neither 0.5 % aqueous nor 0.1 % hydrogel formulations of timolol have exerted noteworthy effects on systolic (SAP) or diastolic (DAP) arterial pressures, probably because of a compensatory increase in systemic vascular resistance due to the attenuation of HR. Ophthalmic timolol does not exert remarkable effects on pulmonary parameter peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV1) in non-asthmatic patients. CYP2D6 activity is clearly associated with the pharmacokinetic parameters, particularly when 0.5 % aqueous solution of timolol is used: peak plasma concentration, elimination half-life and area-under-the-curve are highest in CYP2D6 poor metabolizers. Finally, since there is a correlation between the plasma level of timolol and several haemodynamic effects - especially HR in the state of elevated beta-adrenergic tonus - the CYP2D6 poor metabolizers may be more prone to bradycardia during treatment with (aqueous) ophthalmic timolol.

    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

    Anesthesiological management of patients with Takotsubo syndrome (TTS) is a challenge of questions related to physiopathology, prognosis, and trigger causes. Relative rarity of this disease and lack of wide literature do not allow to state any negative or positive effect of the variety of drugs available for anesthesia. The authors report a case of a woman with a clear diagnosis of TTS and anxiety disorder, who underwent to cataract extractions at both eyes at two different times. Clinical management is described, from preoperative assessment until discharge of the patient. In both cases, surgery was successfully performed using remifentanil Target Controlled Infusion sedation in spontaneous ventilation. In this article, the authors suggest the possible cardioprotective role of remifentanil in this kind of pathology, focusing on its advantageous sedating action that guarantees a stress-free condition, while maintaining control on respiratory drive.

    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.

    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. PMID:22833553

    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.

    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

    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

    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.

    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.

    The aim of molecular imaging techniques is the visualization of molecular processes and functional changes in living animals and human patients before morphological changes occur at the cellular and tissue level. Ophthalmic molecular imaging is still in its infancy and has mainly been used in small animals for pre-clinical research. The goal of most of these pre-clinical studies is their translation into ophthalmic molecular imaging techniques in clinical care. We discuss various molecular imaging techniques and their applications in ophthalmology. PMID:24529711

    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.

    Objective To investigate whether patients with a history of preeclampsia have an increased risk of long-term ophthalmic complications. Study Design A population-based study comparing the incidence of long-term maternal ophthalmic complications in a cohort of women with and without a history of preeclampsia. Results During the study period, a total of 103,183 deliveries met the inclusion criteria; 8.1% (n = 8,324) occurred in patients with a diagnosis of preeclampsia during at least one of their pregnancies. Patients with preeclampsia had a significantly higher incidence of long-term ophthalmic morbidity such as diabetic retinopathy and retinal detachment. In addition, a positive linear correlation was found between the severity of preeclampsia and the prevalence of future ophthalmic morbidities (0.3 vs. 0.5 vs. 2.2%, respectively). Kaplan-Meier survival curve indicated that women with preeclampsia had higher rates of total ophthalmic morbidity (0.2 vs. 0.4%, for no preeclampsia and with preeclampsia, respectively; odds ratio = 2.06, 95% confidence interval: 1.42-2.99; p < 0.001). In a Cox proportional hazards model, adjusted for confounders, a history of preeclampsia remained independently associated with ophthalmic complications. Conclusion Preeclampsia is an independent risk factor for long-term maternal ophthalmic morbidity, specifically diabetic retinopathy and retinal detachment. This risk is more substantial depending on the severity of the disease. PMID:26871904

    The vascular type of Ehlers-Danlos syndrome (vEDS) is an autosomal dominant hereditary disease characterized by connective tissue fragility throughout the body, including the arteries, viscera, and gastrointestinal tract. We report a case in which we performed transvenous embolization (TVE) via direct superior ophthalmic vein (SOV) approach to treat a direct carotid-cavernous fistula (CCF) in a patient with Ehlers-Danlos syndrome (EDS). The patient was a 37-year-old woman who developed tinnitus in her left ear and a headache during examination in the outpatient clinic of another hospital in order to make a definitive diagnosis of vEDS, and she was referred to our hospital and examined. Based on the results of all of the studies she was diagnosed with a CCF. Conservative treatment was attempted, but was not very effective. Because of progressing aphasia, TVE was performed via the SOV direct cut. There were no intraoperative or postoperative complications. It has been reported that cerebral angiography is generally contraindicated in vEDS and that the morbimortality associated with endovascular treatment is very high. When performing treatment it is necessary to be sufficiently aware of the risks it entails. PMID:24418783

    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.

    Topical ocular medications have been widely prescribed and successfully used in children for the management of different ophthalmic disorders. We present 2 infants admitted to our pediatric intensive care unit who developed altered state of consciousness, hypotonia, hypothermia, bradycardia, and apnea after instillation of ophthalmic drops. The second infant also had hypotension and broncho-obstruction. Few days before admission, both infants were diagnosed with congenital glaucoma, and topical antiglaucoma treatment was initiated. Ophthalmic drops with brimonidine and brinzolamide were prescribed to both patients, whereas the second infant also received topical timolol. After elimination of other possible causes, the diagnosis of intoxication with topical antiglaucoma medications was established. After discontinuation of eye drops and vigorous symptomatic treatment, both infants recovered without sequels. Topically applied ophthalmic drops may cause life-threatening systemic adverse effects in infants, such as central nervous system depression and cardiogenic shock. Moreover, these 2 patients illustrate the importance of careful evaluation of all topical medications and their consideration as possible causes of the derangements in critically ill infants.

    The impact of prior neuro-ophthalmic syndromes on the performance on vision-based neuropsychological tasks in patients with multiple sclerosis (MS) is unknown. Two groups of MS participants, one with (Msos+) and the other without (Msos-), a history of neuro-ophthalmic syndromes, underwent neuropsychological assessment and were compared with healthy age- and education-matched controls (HC). Participants with Msos+ performed significantly worse on the symbol digit modalities test than the Msos- (P < 0.03) and the HC groups (P < 0.01) and coding (P < 0.01). A clinical history of neuro-ophthalmic syndromes is associated with reduced performance on visual processing speed tasks. PMID:26132964

    Even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. We have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-back pain and steppage gait who was operated on for prolapsed lumbar disc herniation. Intraoperatively his lumbar disk was discovered to be black. The alkaptonuria diagnosis was considered after histopathological examination of the black disc material and elevated urinary concentration of homogentisic acid confirmed the diagnosis. To our knowledge, this presentation has not been reported previously in literature. PMID:27200402

    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

    Cavernous sinus (CS) dural arteriovenous fistula (dAVF) patients presenting with only headache as an initial symptom are not common. Patients with CS-dAVF commonly present with symptoms related to their eyes. In all three patients, headache was the initial symptom. Other symptoms related to the eyes developed 1 - 7 months after headache. In one patient, headache was controlled by sumatriptan succinate, but not diclofenac sodium or loxoprofen sodium. In another patient, headache was controlled by loxoprofen sodium. In the third patient, headache was improved by stellate ganglion block. In all patients, magnetic resonance angiography (MRA) in the early stage of the clinical course showed abnormal blood flow in the CS. However, reflux to the superior ophthalmic vein (SOV) was not detected. As treatment, transarterial and transvenous embolizations were necessary for one patient, and transvenous embolization was performed for another patient with significant blood flow to the SOV and cortical veins. On the other hand, manual compression of the bilateral carotid arteries at the neck resulted in disappearance of the fistula in the third patient. In all patients, the symptoms improved after the disappearance of blood reflux to the CS. The refluxed blood to the CS might cause elevation of the CS pressure and stimulate the trigeminal nerve in the dural membrane, resulting in headache before developing reflux in an anterior direction. CS-dAVF could induce both migraine and common headache. In cases with blood reflux to the CS on magnetic resonance imaging and/or MRA even without eye symptoms, a differential diagnosis of CS-dAVF should be taken into consideration. PMID:26985257

    Members of the British Ophthalmic Anaesthesia Society were surveyed using a postal questionnaire. The response rate was 72.3%. Respondents were asked about starvation before regional anaesthesia for cataract surgery, the use of sedation in these patients, monitoring and if oxygen supplementation was given. The results show that most patients are not starved before this type of regional anaesthesia, and that the majority of patients receive no supplementary sedation or intravenous analgesia. Over 70% of patients received oxygen supplementation. PMID:11437763

    The diopter power and magnification matrices characterize the first-order properties of ophthalmic lenses for different gaze directions. Therefore an efficient method to compute them is highly valuable in ophthalmic lens design and optical performance simulations. I present a novel method to numerically compute these matrices in ophthalmic lenses comprising any set of arbitrary surfaces. The method is based on computing one base ray, along the gaze direction, and two rays close to it. These two rays are obtained varying a small parameter that indicates their separation from the base ray. The method was validated comparing the results with a single refractive surface where exact solutions are directly obtained.

    Tafluprost ophthalmic solution 0.0015 % preserved with benzalkonium chloride (BAK) 0.001 % is available in several Asian countries, including Japan. In pivotal trials, BAK-preserved tafluprost ophthalmic solution 0.0015 % lowered intraocular pressure (IOP) more effectively than placebo in Asian patients with normal-tension glaucoma and was at least as effective as latanoprost ophthalmic solution 0.005 % in Asian patients with primary open-angle glaucoma or ocular hypertension. In other prospective studies in Asian patients with glaucoma or ocular hypertension, tafluprost ophthalmic solution 0.0015 % was at least as effective as latanoprost ophthalmic solution 0.005 % or travoprost ophthalmic solution 0.004 % in terms of IOP lowering, and was considered easier to use and/or store. The efficacy of tafluprost ophthalmic solution 0.0015 % was maintained in the longer term. Tafluprost ophthalmic solution 0.0015 % was generally well tolerated. In conclusion, BAK-preserved tafluprost ophthalmic solution 0.0015 % remains a useful option for the treatment of Asian patients with glaucoma and ocular hypertension. PMID:27225879

    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

    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.

    Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by a mutation in the huntingtin gene. The whole nervous system, including visual analyzer, is involved in the pathogenesis of the disease. Various ocular sings can be found in both preclinical and clinical stages of HD. Specific retinal damage, namely, abnormal proteins formation, photoreceptor degeneration and retinal remodeling, has been studied in animal models. Functional changes in occipital lobe activity and its atrophy as well as degeneration of visual pathways can already be present in the early stages of the disease. Oculomotor symptoms of HD include disturbed visual fixation, slower tracking eye movements and saccades, and suppressed vestibulo-ocular reflex. Visual perceptual disorders, such as visuospatial difficulties, problems of stimulus identification and motion perception, along with decreased contrast sensitivity, have also been described. The possibility of using certain ophthalmic parameters as biomarkers of HD is being discussed. PMID:26845877

    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. PMID:25968930

  12. Measurement of spherical and cylindrical power in ophthalmic lenses based in the change of lateral amplification

    In this article, we present a new technique to measure spherical and cylindrical power in ophthalmic lenses. This method is based in the change of lateral amplification produced by an optical system when introducing an ophthalmic lens. Ophthalmic lens power is calculated by considering the change in image size from a reference object and its own image seen through the ophthalmic lens. Mathematical analysis is presented along with the experimental setup and the obtained results. Several algorithms were applied to the obtained results as a method to compensate the error in order to fit into ISO 8598 specifications.

    The study aimed at finding out the clinicopathologic, ophthalmic and visual profiles, management and outcome of mucoceles of the paranasal sinuses in Nigerians. The study was a retrospective review of 20 cases of mucoceles who presented to the ENT clinic and referred to the eye clinic of the University College Hospital Ibadan, Nigeria. These included nine males and 11 females with a male:female ratio of approximately 1:1. Mucoceles commonly involved more than one sinus on the same side. The sinuses commonly involved were the frontoethmoidal sinuses, frontal sinus and maxillary sinuses. The preoperative visual acuity in 16 (80%) patients was 6/4-6/9, three (15%) had between 6/9-6/18, and one (5%) patient was CF ("count fingers") in the affected eyes. The majority (90%) of our patients presented with multiple ophthalmic features; however, proptosis was the most popular and ophthalmic presentation and occurred in 15 (75%) patients. Proptosis was nonaxial in all cases with inferior, lateral or inferolateral displacement. Degree of proptosis ranged from 1-20 mm. Other presentations were squint (leading to diplopia) observed in one (5%) patient and epiphora in another [one (5%)] patient. Poor vision appeared to be the main problem in one (5%) patient, while in another [one (5%)] patient, the affected eye was completely immobilized. One (5%) patient presented with orbital cellulitis. Common radiological findings included classical expansive appearance with loss of the normal scalloping appearance with dehiscence of the wall of the affected sinus as was observed in nine (45%) of our patients. All 20 patients had excision of mucoceles (frontoethmoidectomies). At surgery, 11 (55%) patients had a combination of dehiscence of medial and/or posterior walls, and/or floor of the orbit. Materials evacuated were mucopurulent in 15 (75%) cases, moldy in three (15%) and cheesy in two (10%). Nine (45%) patients had intact walls. Three (15%) patients developed orbital cellulitis as

  14. 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.

  18. Ocular and systemic adverse effects of ophthalmic and non ophthalmic medications.

    PubMed

    2011-01-01

    Information related to adverse drug effects caused by ocular medications and ocular adverse effects of systemically administered drugs has increased over the last several decades. Here we review the medical literature over the last four decades to both quantitatively and qualitatively determine the adverse effects of ocular drugs and ocular toxicity of non-ocular drugs. A systematic bibliographic review of the literature was performed with the following terms: "drug treatment", "drug therapy", "ocular adverse effects", "ocular side effects", "ocular toxicity", "systemic side effects", "systemic adverse effects", "systemic toxicity", "ocular drug" and "ophthalmic drug" using the Boolean operators or, and, not. Searches focused on: (1) Ocular side/adverse effects of ophthalmic drugs; (2) Ocular side/adverse effects of systemic drugs; (3) Systemic side/adverse effects of ophthalmic drugs. PubMed was used to perform searches. Limits included: species, human and field tag, abstract/title, dates from 01/01/1971 to 31/12/2010. A sub-selection of references was made by discarding articles that were irrelevant for the topics listed above. Adverse effects of alpha2-adrenergic agonists, beta-adrenergic antagonists, quinine derivatives and antituberculosis agents appear in the literature throughout the period of the review. Adverse effects of newer drugs such as amiodarone, phosphodiesterase 5 inhibitors, antiepileptics, tamoxifen, and its interactions have been published principally in the last two decades. It is imperative for patient safety that knowledge of the adverse effects of drugs on the eye whether topically or systemically administered, and the possible systemic effects of drugs given as ophthalmic medications be emphasized to clinicians.

  19. Ophthalmic Disorders in Adults with Down Syndrome

    PubMed Central

    Krinsky-McHale, Sharon J.; Jenkins, Edmund C.; Zigman, Warren B.; Silverman, Wayne

    2012-01-01

    A myriad of ophthalmic disorders is associated with the phenotype of Down syndrome including strabismus, cataracts, and refractive errors potentially resulting in significant visual impairment. Ophthalmic sequelae have been extensively studied in children and adolescents with Down syndrome but less often in older adults. In-depth review of medical records of older adults with Down syndrome indicated that ophthalmic disorders were common. Cataracts were the most frequent ophthalmic disorder reported, followed by refractive errors, strabismus, and presbyopia. Severity of intellectual disability was unrelated to the presence of ophthalmic disorders. Also, ophthalmic disorders were associated with lower vision-dependent functional and cognitive abilities, although not to the extent that was expected. The high prevalence of ophthalmic disorders highlights the need for periodic evaluations and individualized treatment plans for adults with Down syndrome, in general, but especially when concerns are identified.

  20. Sophisticated instrumentation and ophthalmic ultrasonography.

    PubMed

    Buschmann, W

    1992-01-01

    Formerly, ophthalmic ultrasonography was leading in view of high-performance apparatuses and transducer probes: e.g., the first array-scanner in the world was built for ophthalmic use. Within the past 2 decades, however, high-tech innovations were merely developed for other medical specialties. These were studied in view of their use for ultrasonography of eye and orbit. The combination of B-scan and Doppler techniques facilitates detection of orbital vessels. The resolution of ophthalmic digital B-scan video images proved poorer than crt-B-scans. A digital memory, however, is advantageous. But one high-resolution crt-type B-scan needs more than one disc storage capacity. "Frontline digitalization" could help to reduce the amount of data. Array transducers are now available in small sizes and could better show structure movements, but they were not yet adapted to ophthalmic use. This applies as well to annular arrays and dynamic focusing. Different methods of 3-dimensional scanning and (Pseudo-) 3-dimensional imaging might renew Baum's and Coleman's early work. PMID:1332387

    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

  10. Numerical implementation of generalized Coddington equations for ophthalmic lens design

    NASA Astrophysics Data System (ADS)

    Rojo, P.; Royo, S.; Ramírez, J.; Madariaga, I.

    2014-02-01

    A method for general implementation in any software platform of the generalized Coddington equations is presented, developed, and validated within a Matlab environment. The ophthalmic lens design strategy is presented thoroughly, and the basic concepts of generalized ray tracing are introduced. The methodology for ray tracing is shown to include two inter-related processes. Firstly, finite ray tracing is used to provide the main direction of propagation of the considered ray at the incidence point of interest. Afterwards, generalized ray tracing provides the principal curvatures of the local wavefront at that point, and its orientation after being refracted by the lens. The curvature values of the local wavefront are interpreted as the sagital and tangential powers of the lens at the point of interest. The proposed approach is validated using a double-check of the calculated lens performance in the spherical lens case: while finite ray tracing is validated using a commercial ray tracing software, generalized ray tracing is validated using a software application for ophthalmic lens design based on the classical version of Coddington equations. Equations of the complete tracing process are developed in detail for the case of generic astigmatic ophthalmic lenses as an example. Three-dimensional representation of the sagital and tangential powers of the ophthalmic lens at all directions of gaze then becomes possible, and results are presented for lenses with different geometries.

    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

    Ultrahigh resolution ophthalmic OCT has been performed in more than 250 eyes of 160 patients, demonstrating unprecedented visualization of intraretinal morphology of several retinal pathologies. and therefore the potential to enhance sensitivity and specificity for early ophthalmic diagnosis as well as to monitor the efficacy of therapy. In addition, it might contribute to a better understanding of ocular pathogenesis. This is demonstrated by investigating both normal retinal morphology in an animal model and the impairment of the photoreceptor layer in different macular pathologies.

    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.

    Takayasu's arteritis (TA) is a medium and large vessel vasculitis, defined as a nonspecific aortitis that usually involves the aorta and its branches Kobayashi and Numano (2002). Its etiology remains unclear, and its complications are diverse and severe, including stenosis of the thoracic and abdominal aorta, aortic valve damage and regurgitation, and stenosis of the branches of the aorta. Carotid stenosis, coronary artery aneurysms, and renal artery stenosis resulting in renovascular hypertension are also reported sequellae of TA Kobayashi and Numano (2002). The disease was first described in Japan, but has also been diagnosed in India and Mexico Johnston (2002). Its incidence in the United States has been quoted as 2.6 patients per 1,000,000 people/year Johnston (2002). In Japan, its incidence is 3.6 patients per 1,000,000 patients/year and prevalence is 7.85 patients per 100,000 per year Morita et al. (1996). The natural history of this disease, which is commonly present in Asian populations, has only recently been studied in Hispanic patients despite the notable incidence and prevalence of TA in Mexican, South American, and Indian populations (Johnston 2002, Gamarra et al. 2010 ). We present three cases of Hispanic patients who presented with TA at Olive-View-UCLA Medical Center (OVMC). We review their clinical and radiographic presentations. Finally, we review the literature to compare the clinical features of our three patients with data regarding the presentation of TA in more traditional Asian populations. PMID:23251184

    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.

    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

    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

    Ocular drug delivery formulations must meet anatomical, biopharmaceutical, patient-driven and regulatory requirements. Mucoadhesive polymers can serve as a better alternative to currently available ophthalmic formulations by providing improved bioavailability. If all requirements are addressed, a polymeric formulation resembling the tear film of the eye might be the best solution. The optimum formulation must not have high osmotic activity, should provide appropriate surface tension, pH and refractive index, must be non-toxic and should be transparent and mucoadhesive. We would like to highlight the importance of in vitro polymer testing from a pharmaceutical aspect. We, therefore, carried out physical-chemical investigations to verify the suitability of certain systems for ophthalmic formulations. In this work, in situ gelling, mucoadhesive thiolated poly(aspartic acid)s were tested from ophthalmic formulation aspects. The results of preformulation measurements indicate that these polymers can be used as potential carriers in ophthalmic drug delivery. PMID:26556306

    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.

    The Electrodiagnostic Neurophysiological Automated Analysis (ENAA) telematic system was developed in the EU EUREKA project. To validate the system 2500 electrodiagnostic tests were administered in a standardized manner during a three-year period. The tests were performed on 70 normal subjects and 500 patients in five laboratories in three European countries. The data were transmitted to the Bristol Telematic Electrodiagnostic Centre in the Bristol Eye Hospital. Data from normal subjects were not significantly different between laboratories. Data from patients were reported upon and the conclusions transmitted to the place of origin. The system provided the remote consultant with multimedia data, including medical images such as colour fundus photography and angiography, video and sound. PMID:9218382

    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.

    Cytotoxic T-lymphocyte-antigen 4 (CTLA-4) is an essential negative regulator expressed on regulatory T cells (Tregs) and activated T cells. Germline heterozygous mutations in CTLA4 lead to haploinsufficiency of CTLA-4, resulting in the development of an autosomal dominant immune dysregulation syndrome with incomplete penetrance. We report here a Japanese patient with this disorder who has a novel heterozygous single nucleotide insertion, 76_77insT (p. L28SfsX40), in the CTLA4 gene. Peripheral blood mononuclear cells from the patient showed decreased frequency of CTLA-4(high) cells in CD4(+)FOXP3(+) cells following CD3/CD28 stimulation. The patient experienced hypogammaglobulinemia, recurrent pneumonia, esophageal candidiasis, cytomegalovirus-positive chronic gastritis, chronic and severe diarrhea, and type 1 diabetes mellitus. Moreover, the patient developed multifocal gastric cancer, histologically poorly and well-differentiated adenocarcinomas, associated with chronic atrophic gastritis and intestinal metaplasia. Previously, 23 symptomatic cases with heterozygous CTLA4 mutations have been reported. Including the case presented here, 3 of the 24 cases (12.5%) developed gastric cancer. Notably, 2 of 3 patients presented similarly multifocal adenocarcinomas associated with atrophic gastritis and intestinal metaplasia. Predisposition to gastric cancer has been also reported in CVID patients. These clinical observations suggest that gastric cancer is a disease commonly associated with autosomal dominant immune dysregulation syndrome due to CTLA4 mutation. PMID:26644313

    Objective: To examine the significance of VZV-IgG (IgG) enzyme immunoassay (EIA) and the determination of peripheral blood lymphocyte counts in the diagnosis of ophthalmic zoster sine herpete (ophthalmic ZSH). Method: Clinical case-control study with a sample of 65 patients with ophthalmic ZSH (16 males and 49 females; mean age 56 ± 18 years) in whom pressure elicited pain in tender points of Valleix (tender points of sites at which the trigeminal nerve appears subcutaneously). A total of 41 healthy controls (17 males and 24 females, mean age 48 ± 21 years) were also recruited. In each group, IgG and lymphocyte count were determined upon receiving the consent of patients. Multiple logistic regression analysis was used to evaluate the factors associated with diagnosis of ophthalmic ZSH. Odds ratios and 95% confidence intervals (CI) were determined for each variable. Results: Lymphocyte count in the patients with ophthalmic ZSH was significantly low, though there were no significant differences in age, gender, and IgG between the two groups. Multiple logistic regression analysis revealed that lymphocytes pose a significant prognostic factor, and in case of 1,800 lymphocytes/μl or more, the odds ratio to less than1,800 lymphocytes/μl was 0.29 (95% CI: 0.12–0.72). Conclusion: Patients with orbital pain should be suspected as having ophthalmic ZSH as this allows for the determination of lymphocyte counts after tender points were confirmed. The swift diagnosis of ophthalmic ZSH and the administration of antiviral drugs from an early stage improve the subjective symptoms of the patient and is regarded as necessary to reduce the risk of severe complications.

    Background Cardiac asthma is common, but has been poorly investigated. The objective was to compare the characteristics and outcome of cardiac asthma with that of classical congestive heart failure (CHF) in elderly patients. Methods Prospective study in an 1,800-bed teaching hospital. Results Two hundred and twelve consecutive patients aged ≥ 65 years presenting with dyspnea due to CHF (mean age of 82 ± 8 years) were included. Findings of cardiac echocardiography and natriuretic peptides levels were used to confirm CHF. Cardiac asthma patients were defined as a patient with CHF and wheezing reported by attending physician upon admission to the emergency department. The CHF group (n = 137) and the cardiac asthma group (n = 75), differed for tobacco use (34% vs. 59%, p < 0.05), history of chronic obstructive pulmonary disease (16% vs. 47%, p < 0.05), peripheral arterial disease (10% vs. 24%, p < 0.05). Patients with cardiac asthma had a significantly lower pH (7.38 ± 0.08 vs. 7.43 ± 0.06, p < 0.05), and a higher PaCO2 (47 ± 15 vs. 41 ± 11 mmHg, p < 0.05) at admission. In the cardiac asthma group, patients had greater distal airway obstruction: forced expiratory volume in 1 second of 1.09 vs. 1.33 Liter (p < 0.05), and a forced expiratory flow at 25% to 75% of vital capacity of 0.76 vs. 0.99 Liter (p < 0.05). The in-hospital (23% vs. 19%) and one year mortality (48% vs. 43%) rates were similar. Conclusion Patients with cardiac asthma represented one third of CHF in elderly patients. They were more hypercapnic and experienced more distal airway obstruction. However, outcomes were similar. PMID:17498318

    We aimed to compare outcomes of sepsis patients according to their hemodynamic presentation: cryptic shock (CS), cryptic to overt shock (COS), and overt shock (OS). We analyzed the sepsis registry for adult patients who presented to the emergency department (ED) of a tertiary hospital and met the criteria for severe sepsis or septic shock between August 2008 and March 2012. We classified the patients as having CS, COS, or OS. "Cryptic shock" was defined as severe sepsis with a lactate level of 4 mmol/L or greater and normotension, "COS" was defined as initial CS that progressed to septic shock within 72 h, and "OS" was defined as septic shock on ED arrival. The primary outcome was in-hospital mortality. We performed a multivariable logistic regression analysis to assess variables related to in-hospital mortality and a multivariable Cox regression analysis to assess predictive factors for progression to OS in patients who initially showed CS. A total of 591 patients were included. We assigned 187 (31.6%) patients to the CS group, 157 (26.6%) patients to the COS group, and 247 (41.8%) patients to the OS group. There was a significant difference in unadjusted in-hospital mortality among groups (7.0% in the CS group, 27.4% in the COS group, and 21.9% in the OS group; P < 0.01). Multivariable analysis showed an odds ratio (OR) for in-hospital mortality of 0.17 (95% confidence interval, 0.07 - 0.40; P < 0.01) for the CS group and 0.83 (95% confidence interval, 0.46 - 1.49; P = 0.54) for the COS group compared with the OS group. A higher blood lactate concentration and respiratory failure were significant risk factors for progression to OS. In conclusion, CS without deterioration to hypotension during initial treatment showed significantly lower mortality than OS. The mortality from CS that progressed to apparent hypotension, however, was comparable to the mortality associated with OS. PMID:24978884

Designed to preserve and restore vision on an international scale, the ICO initiative, "Refocusing Ophthalmic Education," enhances ophthalmic education of residents, subspecialists, medical students, and allied eye care personnel by redefining the most effective ways to teach and in creating beneficial educational opportunities. The "Teaching the Teachers" program helps ophthalmic educators incorporate more effective methods of training and continuing professional development to meet societal needs, achieved in part through regional courses for residency program directors; symposia, and keynote talks presented by ICO's World Ophthalmology Educational Colloquium, Conferences for Ophthalmic Educators, and ophthalmic surgical competency rubrics. Recognizing that standardized curricula are essential for consistent ophthalmic education, the ICO has developed a curricular framework whereby goals, expectations, knowledge base, competencies, and technical training are delineated. The ICO is defining worldwide models of team training and compiling best practice, which will include training-program accreditation to ensure improvement in the education of ophthalmologists. International Council of Ophthalmology Web-based teaching courses, a Webinar Network, and a technology blog further support information and communication technologies for teaching and learning. At the ICO's Center for Ophthalmic Educators (educators.icoph.org), trainers will find valuable teaching resources in multiple languages as well as ways to share ideas and collaborate with peers and other ophthalmic educators.

    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

    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.

    EST, proteomic, and antibody capture assays are revealing a level of tear film protein complexity far greater than previously appreciated. A systems biology approach will be needed to fully appreciate function as tear protein doses fluctuate in time through different conditions. Although consensus is growing on what fully constitutes the human tear proteome, questions remain about the source and significance of the ∼256 tear proteins designated as ‘intracellular’. Many of these may derive from normal cellular turnover and could therefore be informative. A further >183 are designated as ‘extracellular’. Surprisingly, only 4 – 5% of these appear to be dysregulated in the three forms of dry eye preliminarily examined to date. Some differ and a couple overlap, suggesting that disease-specific signatures could be identified. Future dry eye treatment might include recombinant tear protein rescue as a personalized ophthalmic approach to ocular surface disease. PMID:18677231

    Local anesthesia administration prior to ophthalmic surgery involves inserting a syringe needle into a confined intraorbital space at the proper position, angle and depth. During this procedure ocular structures must remain unhurt and systemic complications must be avoided while achieving quick akinesia and analgesia. Animal cadavers do not emulate human anatomy accurately and human subject based training entails risk to the patient. Therefore, a training system that closely replicates the human ocular and orbital anatomy and provides the trainee with real-time feedback on the safety and effectiveness of the block administered would help reduce risks involved with real life procedures. This paper presents an anatomically accurate, rapid-prototyped manikin based training system for ophthalmic anesthetic blocks. The depth of penetration of the needle, the proximity of the needle to extraocular muscles and the touch of the needle to the muscles or optic nerve is detected by a multi-electrode electric field/capacitive sensing system. The eye structure of the manikin does not have any electrical connections to it, rendering it replaceable, thus, enabling the emulation of anatomical variations due to pathologies of the eye. A virtual instrument measures and computes the position of the needle and displays it to the trainee through an intuitive GUI with a 3D display of the orbital anatomy. The proposed capacitive sensing scheme has been validated by tests performed on a prototype system, thus demonstrating its usefulness for practical training purposes. PMID:25361511

  5. Benign adrenal cyst presenting in a pregnant patient.

    Cystic lesions of the adrenal gland are uncommon, most often diagnosed incidentally during diagnostic imaging or autopsy. An adrenal cyst presenting as a pelvic mass in pregnancy offers the clinician a diagnostic and therapeutic dilemma. A 28-year-old black female presented for routine obstetric care at 26 weeks' gestation and was found on examination to have a 40-cm pelvic-abdominal mass. Ultrasound confirmation revealed the mass to be cystic and arising from the right pelvis. Laboratory tests including hematocrit, white blood cell count, electrolytes, rapid plasma reagin (RPR), and CA-125 were within normal limits. The patient underwent exploratory laparotomy and a 40 x 20 cm right adrenal cyst was identified and resected. Postoperatively, the patient developed preterm labor and delivered a 955-g infant; the infant was discharged home 3 months later with bronchopulmonary dysplasia and delayed developmental milestones. The woman was discharged home without complication on postoperative Day 8. Accurate preoperative determination of the origin of a pelvic mass occurring in pregnancy is helpful in timing therapeutic intervention. Use of ultrasound and magnetic resonance imaging (MRI) modalities can provide detailed anatomical information without risk to mother or fetus. Conservative management of adrenal cyst in pregnancy may lower the morbidity and mortality of the mother and fetus. PMID:9376006

    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

    This qualitative study offers insight into the experiences, expectations, perceptions and beliefs that may lead to laparoscopic adjustable gastric band patients' failure to achieve expected weight loss and seek revisional bariatric surgery. The 23 participants from two sites were interviewed and data were analysed from a grounded theory methodology in order to build a causal model. Analysis of participants' reports identified 'unrealistic expectations of the LAGB' as the core category. Additionally, the restriction of the band had a negative impact on participants' social interactions, leading to feelings of deprivation and, thus, to a desire for reward from food choices and consequently an increase of consumption of high-calorie-dense foods. These foods were chosen because of their specific texture or ability to provide reward. The resulting increase in weight or failure to achieve excess weight loss, led to feelings of shame and loneliness and emotional eating resulting in increased the consumption of rewarding foods. Thus, identifying unrealistic expectations of laparoscopic adjustable gastric band (LAGB) and emotional eating behaviours are important in those who are present initially for primary bariatric and revisional bariatric surgery, as they may contribute specifically to these patients' weight regain and consequent failure to achieve excess weight loss.

    2012-01-01

    A 55-year-old HIV-negative white male presented with right ear deafness, right axillary lymphadenopathy, and weight loss. Laboratory findings included anemia, marked leukocytosis, and thrombocytopenia. Examination of the peripheral smear demonstrated the presence of increased circulating blast-like cells of intermediate size, with basophilic cytoplasm and nuclei with open chromatin. MRI of the brain was compatible with hemorrhagic labyrinthitis. Excisional biopsy of the axillary mass revealed an enlarged lymph node with effaced architecture and “starry sky” appearance. The cells expressed CD20, CD10, BCL6, and surface kappa immunoglobulin light chain, with a high proliferative index by immunohistochemistry and flow cytometry. Subsequent bone marrow biopsy was hypercellular (approximately 95%), with blast-like cells virtually replacing all hematopoietic elements. Routine karyotype as well as FISH analysis of bone marrow cells demonstrated rearrangement of the MYC gene at chromosome 8q24 region, IGH/MYC fusion, and additional signal for IGH gene. We present herein a case of sporadic Burkitt lymphoma occurring in a previously healthy HIV-negative male. The unusual clinical findings in this case include the relatively older age at presentation (55 years), an immunocompetent patient who had nodal involvement and leukemic phase of Burkitt, coupled with partial deafness. A brief educational review of this neoplasm is made. PMID:23049564

    Hemophilic pseudotumor is a rare complication of hemophilia, occurring in 1 to 2 percent of individuals with severe factor VIII or factor IX deficiency. A 35-year-old male presented with a swelling in the right lower abdomen for 3 months. There was no history of trauma. Examination revealed a swelling over the right iliac fossa. Right hip showed 30° flexion deformity. Blood investigations like complete blood count, APTT, PT, bleeding and clotting time, and fibrinogen were all normal. Plain radiograph and MRI showed a lytic lesion in the right iliac wing. Excision biopsy of the swelling showed organized hematoma with a fibrous capsule suggestive of a pseudotumor. Further haematological workup like factors VIII and IX was normal. At 2 years follow-up, there was no recurrence. We report this case of pseudotumour in patient without any bleeding disorder. Such case has not been reported in literature to the best of our knowledge. PMID:26000180

    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

    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.

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

    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

    Autism has been reported in untreated patients with phenylketonuria. The authors aimed to explore autism in 15 Tunisian and 4 Algerian phenylketonuria patients, and report their clinical, biochemical and molecular peculiarities. The Childhood Autism Rating Scale and the Autism Diagnostic Interview-Revised were used for the diagnosis of autism. Five exons of phenylalanine hydroxylase gene (7, 6, 10, 11, and 5) were amplified by polymerase chain reaction and directly sequenced. Among these patients, 15 were suffering from autism at the time of evaluation. Six mutations were identified: p.E280K, p.G352Vfs, IVS10nt11, p.I224T, p.R261Q, and p.R252W. There was no correlation between autism and mutations affecting the phenylalanine hydroxylase gene, but the age of diet onset was the determining factor in autistic symptoms' evolution.

    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. PMID:26131832

    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.

    A 76-year-old woman presented with an acute onset of right periocular pain, diplopia, ocular injection, progressive proptosis, and periocular swelling. She had an unremarkable past medical history, and the erythrocyte sedimentation rate and complete blood count were normal. A carotid-cavernous sinus fistula was suspected, and an MRI demonstrated enlargement of the superior ophthalmic vein posterior to the globe and enlargement of the inferior ophthalmic vein throughout its entire course. Cerebral arteriography demonstrated a dural cavernous sinus fistula. The inferior ophthalmic vein was accessed via the inferonasal orbital space and was catheterized for delivery of multiple platinum coils to the cavernous sinus fistula. Follow-up venograms demonstrated occlusion of the fistula. At 2-month follow-up, there was a residual sixth nerve palsy and resolution of symptoms, including proptosis and periocular swelling.

    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.

  9. Surgical Difficulties in a Case of Left Ophthalmic Artery Ruptured Aneurysm Associated with Right ICA hypoplasia - Case Report.

    Mohan, D; Moisa, H; Ciurea, A V

    2015-01-01

    The authors present a rare case of a ruptured left ophthalmic artery aneurysm associated with right ICA hypoplasia in a 49 year old female. The particularity of the case lies in the fact that the patient had a hypoplastic right ICA which was associated with an intracranial aneurysm. In this case we present,surgery was mandatory as it represented the patient'€™s only chance for a favorable outcome, given the lack of an adequate team specialized in endovascular coiling. Unlike many neurosurgical centers in Western Europe and the US where endovascular approaches have overtaken microsurgery, in Romania open microsurgery is frequently performed as it allows neurosurgeons to perfectly control the environment in which they operate and minimizes possible complications of coiling or stenting which become more and more frequent in other countries.

    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. PMID:23024652

    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.

    AIMS—To compare the efficacy and safety of famciclovir with aciclovir for the treatment of ophthalmic zoster.
METHODS—Randomised, double masked, aciclovir controlled, parallel group in 87 centres worldwide including 454 patients with ophthalmic zoster of trigeminal nerve (V1) comprised the intent to treat population. Oral famciclovir 500 mg three times daily or oral aciclovir 800 mg five times daily for 7 days. Assessments included day 0 (screening), days 3 and 7 (during treatment), days 10, 14, 21, 28 and monthly thereafter, up to 6 months (follow up). Proportion of patients who experienced ocular manifestations, severe manifestations and non-severe manifestations; loss of visual acuity was the main outcome measure.
RESULTS—The percentage of patients who experienced one or more ocular manifestations was similar for famciclovir (142/245, 58.0%) and aciclovir (114/196, 58.2%) recipients, with no significant difference between groups (OR 0.99; 95% CI 0.68, 1.45). The percentage of patients who experienced severe and non-severe manifestations was similar between groups, with no significant difference. The prevalence of individual ocular manifestations was comparable between groups. There was no significant difference between groups for visual acuity loss.
CONCLUSION—Famciclovir 500 mg three times daily was well tolerated and demonstrated efficacy similar to aciclovir 800 mg five times daily.

  1. Review of Azithromycin Ophthalmic 1% Solution (AzaSite®) for the Treatment of Ocular Infections

    PubMed Central

    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

    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

    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. PMID:10594423

    Lysosomal diseases represent a large group of genetic storage disorders characterized by a defect in the catabolism of complex molecules within the lysosome. Effective treatments are now possible for some of them given progresses in bone-marrow transplantation, enzyme replacement therapy and substrate reduction therapy. Neurologists and psychiatrists are concerned by these diseases because they can present in adolescence or adulthood with progressive neuropsychiatric signs. Here we focus on late-onset clinical forms which can be met in an adult neurology or psychiatric department. Lysosomal diseases were classified into 3 groups: (1) leukodystrophies (metachromatic leukodystrophy, Krabbe's disease and Salla's disease); (2) Neurodegenerative or psychiatric-like diseases (GM1 and GM2 gangliosidoses, Niemann Pick type C disease, sialidosis type I, ceroid-lipofuscinosis, mucopolysaccharidosis type III); (3) multisystemic diseases (Gaucher's disease, Fabry's disease, alpha and B mannosidosis, Niemann Pick disease type B, fucosidosis, Schindler/Kanzaki disease, and mucopolysaccharidosis type I and II. We propose a diagnostic approach guided by clinical examination, brain MRI, electrodiagnostic studies and abdominal echography. PMID:18033028

    The integrity of the vision channel is often checked using VEP in order to avoiding damaging important tissue during an ophthalmic operation. But the measurement of before operations has strong side effects, it may damage the eyeball. We will introduce a new kind for monitoring ophthalmic operations in this paper. It uses visual electrical evoked potential to check the integrity of the vision access and it can monitor ophthalmic operations and avoid damaging any tissue, so it ensures the safety of the operation.

  8. Patent perspectives for corticosteroids based ophthalmic therapeutics.

    2014-01-01

    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

    2015-02-01

    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.

    Patient candidacy for acute stroke intervention, is currently assessed using brain computed tomography angiography (CTA) evidence of significant stenosis/occlusion (SSO) with a high National Institutes of Health Stroke Scale (NIHSS) (>6). This study examined the association between CTA without significant stenosis/occlusion (NSSO) and lower NIHSS (≤ 6) with transient ischemic attack (TIA) and other good clinical outcomes at discharge. Patients presenting <8 hours from stroke symptom onset, had an NIHSS assessment and brain CTA performed at presentation. Good clinical outcomes were defined as: discharge diagnosis of TIA, modified Rankin Score [mRS] ≤ 1, and home as the discharge disposition. Eighty-five patients received both an NIHSS at presentation and a CTA at 4.2 ± 2.2 hours from stroke symptom onset. Patients with NSSO on CTA as well as those with NIHSS≤6 had better outcomes at discharge (p<0.001). NIHSS ≤ 6 were more likely than NSSO (p=0.01) to have a discharge diagnosis of TIA (p<0.001). NSSO on CTA and NIHSS ≤ 6 also correlated with fewer deaths (p<0.001). Multivariable analyses showed NSSO on CTA (Adjusted OR: 5.8 95% CI: 1.2-27.0, p=0.03) independently predicted the discharge diagnosis of TIA. Addition of NIHSS ≤ 6 to NSSO on CTA proved to be a stronger independent predictor of TIA (Adjusted OR 18.7 95% CI: 3.5-98.9, p=0.001). PMID:24851234

    2013-06-01

    Loteprednol etabonate ophthalmic gel 0.5% (Lotemax(®)) is approved in the USA for the treatment of post-operative inflammation and pain in patients who have undergone ocular surgery. The new gel formulation of loteprednol etabonate offers some potential advantages over the previously available ophthalmic suspension and ointment formulations of the drug. Because the gel is non-settling, a uniform dose of loteprednol etabonate is delivered without the need to vigorously shake the product. The pH of the gel formulation is close to that of physiological tears and the concentration of preservative is low. In clinical trials, loteprednol etabonate ophthalmic gel 0.5% for 14 days was effective, very well tolerated and safe when used for the treatment of post-operative inflammation and pain following cataract surgery. Relative to vehicle, loteprednol etabonate ophthalmic gel 0.5% effectively reduced postoperative ocular inflammation and ocular pain and had a similar overall tolerability, comfort and safety profile. It is associated with a low risk of inducing clinically significant increases in intraocular pressure. In conclusion, loteprednol etabonate ophthalmic gel 0.5% is an additional formulation option for the short-term treatment of post-operative inflammation and pain in patients who have undergone ocular surgery. It provides uniform dosing of a topical ophthalmic corticosteroid that has been demonstrated to be effective and well-tolerated in the treatment of ocular inflammation. PMID:23740411

    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

  13. Ophthalmic Artery Chemosurgery for Less Advanced Intraocular Retinoblastoma: Five Year Review

    PubMed Central

    Abramson, David H.; Marr, Brian P.; Brodie, Scott E.; Dunkel, Ira; Palioura, Sotiria; Gobin, Y. Pierre

    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.

    2010-01-01

    We report on two fluidic lenses that have been developed for ophthalmic applications. The lenses use a circular aperture to demonstrate optical powers between −20 and +20 D and a rectangular aperture to demonstrate astigmatism with values ranging from 0 to 8 D. Measurements of image quality were made with the fluidic lens using a model eye. Both lenses were variable and controllable by adjusting the fluid volume of the lens. To the best of our knowledge this is the first demonstration of a continuously variable lens for control of astigmatism. PMID:19373359

  15. 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.

    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.

  17. The Effect of Bedside Presentations in the Emergency Department on Patient Satisfaction

    2011-01-01

    Background Due to increasing time constraints, the use of bedside presentations in resident education has declined. We examined whether patient satisfaction in the emergency department is affected when first-year residents present at the bedside with attendings. Methods We performed an observational, prospective, nonblinded study in the emergency department of a military teaching hospital. We alternately assigned first-year residents to present a convenience sample of 248 patients to the attending physician at the patient's bedside or away from the patient. We measured patient satisfaction by using the Patient Satisfaction Questionaire-18 (PSQ-18), a validated survey instrument that utilizes a Likert scale, and additional nonvalidated survey questions involving Likert and visual analog scales. Results While the median PSQ-18 score of 74 (95% confidence interval [CI], 72–76) was higher for patient satisfaction when residents made bedside presentations than that for standard presentations, 72 (95% CI, 70–74), the difference did not reach statistical significance (P  =  .33). Conclusion There was no significant difference in overall patient satisfaction between residents' bedside presentations and presentations to attendings away from the patient. Although not significant, the differences noted in PSQ-18 subscales of communication, general satisfaction, and interpersonal manner warrant further investigation. Patients did not appear to be uncomfortable with having their care discussed and with having subsequent resident education at the bedside. Future research on patient satisfaction after implementation of standardized bedside teaching techniques 5 help further elucidate this relationship. PMID:23205195

  18. Infrared. An unseen and unnecessary hazard in ophthalmic devices.

    1987-02-01

    The concept of instrument-induced light damage to the retina is well established. Many have argued that ultraviolet (UV) energy is overwhelmingly responsible and that longer wavelength infrared (IR) energy causes thermal change and plays a minimal role. We suggest that infrared may play a primary role in instrument-induced damage. We measured the radiometric and photometric outputs from commonly used ophthalmic devices in normal use and in IR-blocked conditions. We found IR output to represent a significant portion of the total irradiation produced by these instruments. Infrared was easily and inexpensively minimized without compromising usable visible light in these instruments using an efficient IR filter. The instruments' incandescent lamps, glass envelopes, and optics are poor UV emitters or transmitters. Manufacturers' data do not indicate UV emission. Evidence for UV blocking and IR transmission by the intraocular media is presented. PMID:3574879

    2014-07-01

    Spinal epidural abscess (SEA) is a rare clinical entity. It is less common when the entire epidural space is involved, known as a holocord or panspinal SEA, and it is even less common in a pregnant patient. We report a case of methicillin-resistant Staphylococcus aureus holocord SEA in a 30-year-old female at approximately 22 weeks' gestational age who presented with lumbar pain and pelvic pressure and the urge to bear down. Magnetic resonance imaging of the spine demonstrated extensive SEA and meningitis from the foramen magnum to the lumbar spine that was treated both medically and surgically. The incidence of, clinical presentation of, and risk factors for developing SEA are discussed. If untreated, expanding SEAs produce sensory symptoms and signs, motor dysfunction, and, eventually, paralysis and death. The medical and surgical management of SEA is also discussed. SEA can have an insidious and atypical presentation despite extensive involvement of the epidural space. Therefore, the diagnosis of SEA should always be considered in patients who present to the emergency department with back pain. PMID:25060090

    Cerebral venous thrombosis (CVT) is an uncommon cause of stroke. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare type of hemolytic anemia, frequently associated with thrombophilia. PNH may rarely present with CVT. Approximately, one-third of the patients with CVT develop cerebral hemorrhage. Here, we present a rare combination of CVT presenting with intracerebral hemorrhage in a patient with PNH. High index of suspicion is needed to avoid misdiagnosis. Patient was successfully managed with anticoagulation therapy. PMID:27076714

    Bowel perforation is a rare but life-threatening complication of bevacizumab, a new anticancer treatment. Patients with bowel perforation usually present with acute abdominal symptoms. Here a case history is presented to highlight a pancreatic cancer patient on bevacizumab chemotherapy who developed empyema as the first manifestation of gastric perforation. This unusual presentation warns physicians that bevacizumab-related bowel perforation can arise as a thoracic complication, without typical gastrointestinal manifestations, in an advanced cancer patient.

    2016-08-01

    Erdheim-Chester disease (ECD) is a rare xanthogranulomatous disease in which orbital involvement can have devastating outcomes. Through a case report and review of the ophthalmic literature, we explore orbital findings, disease progression, and treatment options. Cases of orbital involvement in Erdheim-Chester disease were identified in the ophthalmic literature with a PubMed query and review of cited references. A total of 14 publications reporting 19 separate cases that included ophthalmic examination data were identified. Patient ages ranged from 26-77 years with a mean age of 50 years. Seventy-four percent (14/19) were men. Vision progression to no light perception was found in 32% (6/19) of the patients. Reviewed cases reported a variety of medical and surgical treatment approaches, however, only 53% reported cases (10/19) demonstrated disease improvement or stabilization. Erdheim-Chester disease with orbital involvement is a devastating disease with a poor prognosis. Awareness of this entity by the ophthalmologist is important as orbital signs and symptoms may manifest early, and orbital biopsy is often crucial to the definitive diagnosis. PMID:27322549

    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.

    The success of many medical treatments is built on compliance. Electronic monitoring is the most accurate tool to quantify compliance by measuring adherence. In order to assess the efficiency of a recently introduced miniature monitoring device for eye drop application, we evaluated adherence in ophthalmic patients undergoing post-operative short-term topical treatment. This pilot study enrolled 30 outpatients (mean age 61.8 +/- 18.5 years) after cataract (n = 24) and glaucoma filtration surgery (n = 6) applying fixed-combination eye drops containing prednisolone and gentamicin five times daily for 2 weeks. Patients received eye drops in conventional bottles each equipped with a miniature monitoring device recording events of application. Two patients failed to bring back the monitoring device; therefore data collected from only 28 patients could be examined. Data showed highly variable results with a mean dose compliance of 50.2%. Dose compliance was below 25% in approximately one out of five patients. Four cataract patients, but no glaucoma patient, discontinued therapy prematurely. The observed mean dosage interval was calculated for each patient and ranged 4.6-19.7 h. Thirty percent of analysed dosage intervals exceeded 12.0 h. Different patterns of compliance behaviour-like early non-persistence, drug holiday and low treatment frequency could be identified and illustrated using electronic data. Age or gender did not significantly influence compliance rates. Our pilot study demonstrates successful electronic compliance monitoring using a technology capable of continuous data recording over weeks of treatment. The low compliance rate for a relevant part of the patients demonstrates the necessity to study and improve compliance in ophthalmology. In future, new application methods and electronic application devices may improve treatment response in eye care. PMID:20373127

  5. Impact of deep freezing on the stability of 25 mg/ml vancomycin ophthalmic solutions.

    For the treatment of certain eye infections, ophthalmic solutions 'laced' with 25 mg/ml vancomycin are sometimes prepared. Their physical and chemical stability and the maintenance of their sterility were studied after deep freezing at -20 +/- 2 degrees C and thawing, followed or not by refrigeration for 48 h at 4 +/- 2 degrees C. Physical and chemical analysis comprised visual inspection turbidity, determination of pH and osmolality, and assay of vancomycin by high performance liquid chromatography with ultraviolet detection. For microbiological analysis a 25 mg/ml vancomycin ophthalmic solution was filtered through two membranes and cultured on trypticase-soy and Sabouraud-glucose solid media. Any colonies were then counted. These physical, chemical and microbiological analyses demonstrated the stability of 25 mg/ml vancomycin ophthalmic solutions in 5% glucose deep frozen at -20 +/- 2 degrees C for 3 months. The vancomycin concentration varied by no more than 5% of the initial concentration, and no breakdown product was evidenced. Neither pH (mean=3.8 +/- 0.1) nor osmolality (mean=318.3 +/- 5.6 mOsm/kg) varied significantly, and remained compatible with intraocular administration. No particle or bacterial combination was found in the course of the study. The thawing procedure (at ambient temperature or under warm running water from a tap) did not modify the stability of the eye drops. Likewise, storage in a refrigerator for 48 h after thawing did not modify stability. The advantage of storing vancomycin 25 mg/ml ophthalmic solutions for 3 months in deep freeze is that a stock of chemically and microbiologically controlled preparations can be held ready for administration to patients, thereby allowing prompter dispensing, as the eye drops are not made up extemporaneously, while the improved control over production ensures that patients receive solutions of constant quality, as every batch prepared is systematically inspected.

    A method is presented for measuring the modulation transfer function of ophthalmic lenses by use of the generation of laser speckle with an integrating sphere. The measurements are performed with a rectangular double-slit aperture positioned at the output port of the integrating sphere. The distance between the lens and the detector determines the spatial frequency being tested; therefore high frequencies are tested close to the lens and low frequencies are tested far away from the lens. We can conclude that the double-slit method can be a versatile technique for comparing the optical quality of ophthalmic lenses from different makers. PMID:16381521

    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.0.

    Optical coherence tomography (OCT) allows high-resolution imaging of tissue microstructure and is the goldstandard for clinical ophthalmic diagnostics. Recent development of microscope-integrated intraoperative OCT (iOCT) systems has allowed cross-sectional imaging of surgical dynamics, but limitations in real-time visualization of instrument-tissue interactions remain the critical barrier for iOCT-guided ophthalmic surgery. Spatial compounding has been previously presented as a method for acquiring, processing, and visualizing cross-sectional iOCT images of surgical maneuvers. However, spatial compounding trades-off temporal resolution and FOV, which generally limits video-rate visualization to small regions at the tip of surgical instruments. To overcome these limitations, we present methods for automated dynamic surgical instrument tracking iOCT. B-scans are obtained along and orthogonal to the instrument axis and centered at the instrument tip at all times to allow cross-sectional visualization of ophthalmic surgical maneuvers for intraoperative guidance. Surgical instrument tracking has been previously demonstrated using different imaging modalities, including an OCT-integrated scanning probe. However, the latter uses large feature points, which are impractical in a surgical setting. Here, we describe automated stereo-vision instrument tracking, which achieves <250 μm accuracy, using tracking feature points that are easily integrated with ophthalmic surgical instruments. The instrument tracking system was integrated with an iOCT system to provide video-rate instrument tip tracked crosssectional B-scan imaging during ophthalmic surgical maneuvers, allowing visualization of tissue-instrument interactions and providing feedback on positioning, depth of penetration, and tissue compression in cadaveric porcine eyes. Real-time instrument tracked cross-sectional imaging can potentially help guide clinical decision-making during ophthalmic surgery.

    A computerized questionnaire was used to collect information on the presentation of symptoms in all 125 new patients presenting to one general practitioner in the course of one year who were considered to be suffering clinically significant psychiatric disturbance. Comparison was made between the 73 (58%) patients presenting with psychological symptoms and the 52 (42%) patients presenting with somatic symptoms for which no physical explanation was evident at the time of the consultation. Important differences emerged between the groups. Those patients presenting somatic symptoms had lower scores on the tests of psychiatric distress (indicating severity), fewer individual symptoms and fewer severe symptoms than patients presenting with psychological problems. This group also had statistically significant differences in personality profile and reported significantly fewer social problems. Prognosis for both groups was similar in that patients in both groups were equally likely to have a normal psychiatric distress score after six months. Adequate management of somatizing patients calls for vigilance and for improved detection and negotiating skills. Reviewing the computer results with patients helped them discuss their symptoms and the system allowed the general practitioner not only a clinical assessment of these patients' problems but a measure of psychological, social and personality components.

    This study reviewed the presentations of psychiatric patients admitted through the Emergency Department (ED), The Aga Khan University Hospital, Karachi. Psychiatric patients admitted through the ED to the psychiatry ward were compared to those admitted through the same units other than the psychiatry ward, from 2006 to 2010 using medical records. Psychiatric patients were defined as those in whom psychiatry consult was generated and 1127 cases were included in study. There were 550 (48.8%) female patients. Most common presentations in the ED were sleep-related problems (n=205, 15.9%) followed by aggressive behavior (n=191, 14.8%). Depression was the most common diagnosis made in the ED (n=331, 29.3%) and at the time of discharge from the hospital (n=354, 29.5%). Psychiatric patients presenting to the ED had signs and symptoms which one generally disregards. However, these minor indicators can lead to major events in a patient's life. PMID:26008672

    This report describes 30 patients under the age of 30 years with rheumatic aortic stenosis, presenting with combined aortic and mitral stenosis. Three patients had additional tricuspid stenosis. Twenty-eight patients gave a history of rheumatic polyarthritis. The diagnosis was confirmed by right and left heart catheterisation in all. The murmur of aortic stenosis was not initially present in 8 out of 10 patients in congestive heart failure. Aortic valve calcification was not seen. Cineangiography showed a tricuspid aortic valve in all, unlike congenital aortic stenosis. A unique feature of this group was the raised pulmonary vascular resistance in 87 per cent of the patients. The present study shows that patients in India developing aortic stenosis after rheumatic fever do so early in the natural history of the disease. PMID:849390

    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.

    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.

    IgG4-related disease (IgG4-RD) is a distinct entity that frequently occurs in an ophthalmic location. As such, IgG4-RD is not limited to the orbit but may also involve other anatomical structures in and around the eye. Hence, the term 'ophthalmic IgG4-RD' is preferred over 'orbital IgG4-RD.' A high level of suspicion for the diagnosis can be derived from careful clinicoradiologic examination; the use of immunohistochemical staining for IgG4 in the context of characteristic histopathologic features is needed to reach a correct diagnosis. Recently described diagnostic criteria for ophthalmic IgG4-RD address subtle, yet significant, differences from IgG4-RD as seen in other systemic sites. Serum IgG4 titers are neither sensitive nor specific for the diagnosis of IgG4-RD and should not relied upon solely. Although most cases respond well to therapy with glucocorticoids, refractoriness to treatment and relapses are common. They necessitate the use of additional immunotherapy in such patients.

    OBJECTIVE: To evaluate the prevalence of gastroesophageal reflux disease (GERD) in patients presenting with asthma and chronic cough. PATIENTS AND METHODS: The charts of 358 consecutive patients who were referred for ambulatory gastroesophageal pH monitoring to the Lung Centre in Vancouver, British Columbia, were reviewed, and the data of 108 (30%) patients with asthma and 134 (37%) patients with chronic cough were analyzed. The maintenance treatment for GERD was discontinued before patients underwent the pH monitoring study. One hundred eighteen (33%) patients were excluded. RESULTS: Reflux episodes identified reflux events as the percentage of time where the pH was less than four. For asthma patients, 70 (64.8%) had distal total reflux, 50 (46.3%) had distal upright reflux, 41 (38.3%) had distal supine reflux and 73 (67.6%) had other distal refluxes. Proximal total reflux in asthmatic patients was present in 56 (52%), proximal upright reflux in 55 (51%) and proximal supine reflux in 56 (52%) patients. For chronic cough patients, 70 (52.6%) had distal total reflux, 59 (44.4%) had distal upright reflux, 45 (34.4%) had distal supine reflux and 75 (56%) patients had other distal refluxes. In chronic cough patients, proximal total reflux was present in 70 (52%), proximal upright reflux in 80 (60%) and proximal supine reflux in 59 (44%). Presenting respiratory and/or reflux symptoms were absent in approximately 25% of patients with asthma and reflux, and in approximately 50% of patients with chronic cough and reflux. During pH monitoring, symptoms did not differ significantly between those with and without distal reflux in both study groups, except for more significant heartburn in patients with chronic cough and reflux (RR 2.0). CONCLUSIONS: The data of the present study support the observation that there is a high prevalence of GERD in patients with asthma or chronic cough.

    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

    The aim of this review is to use the multimedia aspects of a purely digital online publication to explain and illustrate the highly capable technique of m-sequences in multifocal ophthalmic electrophysiology. M-sequences have been successfully applied in clinical routines during the past 20 years. However, the underlying mathematical rationale is often daunting. These mathematical properties of m-sequences allow one not only to separate the responses from different fields but also to analyze adaptational effects and impacts of former events. By explaining the history, the formation, and the different aspects of application, a better comprehension of the technique is intended. With this review we aim to clarify the opportunities of m-sequences in order to motivate scientists to use m-sequences in their future research. PMID:26818968

    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.

    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. PMID:22923461

    Purpose: To evaluate the feasibility of developing a novel mini drug pump for ophthalmic use. Methods: Using principles of microelectromechanical systems engineering, a mini drug pump was fabricated. The pumping mechanism is based on electrolysis, and the pump includes a drug refill port as well as a check valve to control drug delivery. Drug pumps were tested first on the benchtop and then after implantation in rabbits. For the latter, we implanted 4 elliptical (9.9 × 7.7 × 1.8 mm) non-electrically active pumps into 4 rabbits. The procedure is similar to implantation of a glaucoma seton. To determine the ability to refill and also the patency of the cannula, at intervals of 4 to 6 weeks after implantation, we accessed the drug reservoir with a transconjunctival needle and delivered approximately as low as 1 μL of trypan blue solution (0.06%) into the anterior chamber. Animals were followed up by slit-lamp examination, photography, and fluorescein angiography. Results: Benchtop testing showed 2.0 μL/min delivery when using 0.4 mW of power for electrolysis. One-way valves showed reliable opening pressures of 470 mm Hg. All implanted devices refilled at 4- to 6-week intervals for 4 to 6 months. No infection was seen. No devices extruded. No filtering bleb formed over the implant. Conclusions: A prototype ocular mini drug pump was built, implanted, and refilled. Such a platform needs more testing to determine the long-term biocompatibility of an electrically controlled implanted pump. Testing with various pharmacologic agents is needed to determine its ultimate potential for ophthalmic use. PMID:20126483

    We present a method to measure spherical power in ophthalmic lenses based on the measurement of moiré patterns, using the technique called infinite fringe moiré deflectometry. We develop a theoretical model using a geometrical analysis that was validated by a computer simulation using the LabVIEW software; also we build an experimental setup in which we get experimental data. As results, we obtain a measurement of the spherical power of a set of ophthalmic test lenses in the range of +/- 0.50 to +/- 3.00 diopters. This power is obtained by measuring the separation between each fringe of moiré pattern, from the obtained data we analyze the theoretical model and we make the necessary corrections, using polynomial regression by the method of least squares, to comply with standard ISO8598. At the same time, some components of the experimental setup were being improved to facilitate its implementation and obtain better experimental data.

    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

    Professional discussions about communication in medical settings often ignore the various personal identities that doctors and patients bring to their clinical encounters. From my 26 years as a family physician, and informed by literature from other professional disciplines, I propose an alternate understanding: to think of doctors and patients as a collection of individual identities, each formed by a discrete presentation of self. I describe how at least 5 important presentations of self arise in clinical encounters, including those relating to meaning, community, agency, anxiety, and organism. I frame these presentations of self with the mnemonic ABCDE, briefly review key dimensions of each, and suggest how physicians can reflect on these dimensions in order to find equilibrium in their interactions with patients. Lastly, I submit that finding this balance can reduce relational challenges with patients and enhance the therapeutic effectiveness of doctor-patient communication. PMID:25964409

    In situ gels are systems which are applied as solutions or suspensions and are capable of undergoing rapid sol-to-gel transformation triggered by external stimulus such as temperature, pH etc. on instillation. The aim of the present study was to formulate and evaluate pH responsive in-situ gel for ophthalmic delivery. Ciprofloxacin hydrochloride is popularly used as a broad spectrum antibiotic in the treatment of corneal ulcers of ocular infections. However, rapid dilution on instillation, wash out, poor retention of drug concentration delimit the therapeutic benefits of the drug when used in form of conventional eye drops. Sodium alginate, an ophthalmic gel forming mucoadhesive polymer was chosen as polymer which undergoes instantaneous gel formation due to formation of calcium alginate by virtue of its interaction with divalent cation (Ca+2) present in lachrymal fluid. Hydroxy Propyl Methyl Cellulose (HPMC K4M and E5 0LV) was further incorporated as a viscosity enhancer in order to achieve the desired consistency so as to facilitate sustained drug release. The developed formulations were evaluated for clarity, pH measurement, gelling capacity, drug content, rheological study, and in vitro drug release. Thus, in situ gel based systems containing gums can be a valuable approach for ophthalmic drug delivery when compared to conventional systems. PMID:26949596

    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

    2012-01-01

    Background Temporomandibular disorder (TMD) patients might present a number of concurrent clinical diagnoses that may be clustered according to their similarity. Profiling patients’ clinical presentations can be useful for better understanding the behavior of TMD and for providing appropriate treatment planning. The aim of this study was to simultaneously classify symptomatic patients diagnosed with a variety of subtypes of TMD into homogenous groups based on their clinical presentation and occurrence of comorbidities. Methods Clinical records of 357 consecutive TMD patients seeking treatment in a private specialized clinic were included in the study sample. Patients presenting multiple subtypes of TMD diagnosed simultaneously were categorized according to the AAOP criteria. Descriptive statistics and two-step cluster analysis were used to characterize the clinical presentation of these patients based on the primary and secondary clinical diagnoses. Results The most common diagnoses were localized masticatory muscle pain (n = 125) and disc displacement without reduction (n = 104). Comorbidity was identified in 288 patients. The automatic selection of an optimal number of clusters included 100% of cases, generating an initial 6-cluster solution and a final 4-cluster solution. The interpretation of within-group ranking of the importance of variables in the clustering solutions resulted in the following characterization of clusters: chronic facial pain (n = 36), acute muscle pain (n = 125), acute articular pain (n = 75) and chronic articular impairment (n = 121). Conclusion Subgroups of acute and chronic TMD patients seeking treatment can be identified using clustering methods to provide a better understanding of the clinical presentation of TMD when multiple diagnosis are present. Classifying patients into identifiable symptomatic profiles would help clinicians to estimate how common a disorder is within a population of TMD patients and

    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.

  19. A retrospective study of microscopic polyangiitis patients presenting with pulmonary fibrosis in China

    2014-01-01

    Background Pulmonary involvement is a common feature of MPA. Although alveolar hemorrhage is the most common pulmonary manifestation of MPA, a few recent studies have described instances of MPA patients with pulmonary fibrosis. Pulmonary fibrosis was seen to predate, be concomitant with, or occur after the diagnosis of MPA. The goal of this study was to describe the clinical features and prognosis of microscopic polyangiitis (MPA) patients whose initial respiratory presentation was pulmonary fibrosis. Methods We conducted a retrospective analysis of 19 MPA patients who presented with pulmonary fibrosis at Peking Union Medical College Hospital between 1990 and 2012. Results Of 67 total MPA cases, 19 patients presented with pulmonary fibrosis. There were 8 males and 11 females, with a median age of 63.6 years. Common clinical manifestations included fever (89.5%), cough (84.2%), dyspnea (78.9%) and velcro rales (84.2%). Eleven patients experienced weight loss, several had kidney involvement, and most had an increased erythrocyte sedimentation rate and C-reactive protein. All were positive for myeloperoxidase-anti-neutrophil cytoplasmic antibody (ANCA), with 6 patients being positive at the time of their initial diagnosis of pulmonary fibrosis. Every patient had typical features of usual interstitial pneumonia on High-resolution CT. All were treated with corticosteroids and cyclophosphamide, which lead to an improvement in twelve cases. One of the remaining patients progressed slowly, whereas six died. Conclusions Patients with MPA, who also presented with pulmonary fibrosis in our cohort, were more likely to be older, female, and have extrapulmonic involvement. Most patients had a delayed positive ANCA. Corticosteroids plus cyclophosphamide was the remission-induction treatment scheme for all cases. The current prognosis for MPA patients with pulmonary fibrosis appears to be poor, suggesting that they may be candidates for new therapies. PMID:24468083

    2010-01-01

    This article reports a conversation analytic study of primary care physicians' orientations to different types of patients' problem presentation. Four types of problem presentation are examined: 1. symptoms only; 2. candidate diagnosis; 3. diagnosis implicative symptom description; and 4. candidate diagnosis as background information. The analysis shows that both in receiving the problem presentation at the beginning of the visit and in delivering a diagnosis later on, doctors address the patients' presentations which involved or implied a candidate diagnosis. In contrast, following a symptoms-only type of problem presentation such references predominantly are not made. The study suggests that patients' problem presentation have a crucial role in shaping the doctor's communication patterns also in the phases of consultation in which the patient's active participation is of lesser significance, such as the diagnostic phase. The findings are discussed in relation to the question of patient participation in the medical consultation. The data consist of 86 video-recorded Finnish primary care consultations for upper respiratory tract infection including both child and adult patients. PMID:22049636

    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.

    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. PMID:21979475

    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).

    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

    We conducted a retrospective review of confirmed HIV-TB coinfected patients previously enrolled as part of the SAPiT study in Durban, South Africa. Patients with suspected meningitis were included in this case series. From 642 individuals, 14 episodes of meningitis in 10 patients were identified. For 8 patients, this episode of meningitis was the AIDS defining illness, with cryptococcus (9/14 episodes) and tuberculosis (3/14 episodes) as the commonest aetiological agents. The combination of headache and neck stiffness (78.6%) was the most frequent clinical presentation. Relapsing cryptococcal meningitis occurred in 3/7 patients. Mortality was 70% (7/10), with 4 deaths directly due to meningitis. In an HIV TB endemic region we identified cryptococcus followed by tuberculosis as the leading causes of meningitis. We highlight the occurrence of tuberculous meningitis in patients already receiving antituberculous therapy. The development of meningitis heralded poor outcomes, high mortality, and relapsing meningitis despite ART. PMID:22216407

    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.

    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.

    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.

    The role of sigmoidoscopy and rectal biopsy was investigated in patients referred to an infectious diseases unit with diarrhoea. Seventy-four patients were studied. Nine patients (12%) had inflammatory bowel disease, either ulcerative colitis or Crohn's disease. Thirty-six patients (48%) had infective diarrhoea. A wide variety of conditions accounted for the diarrhoea in the remaining patients. Sigmoidoscopy was abnormal in 25 patients and rectal biopsy in 56. The abnormalities in rectal mucosal histology were classified into six grades. Some patients with infective diarrhoea showed rather characteristic histological changes which may be of diagnostic value. Eight showed features which suggested a diagnosis of inflammatory bowel disease. However, repeat rectal biopsy in the convalescent period showed a striking improvement in the patients with infective diarrhoea. In contrast, the histological changes persisted in the patients with inflammatory bowel disease. Repeat rectal biopsy may be essential before making a firm diagnosis of inflammatory bowel disease in some patients who present with diarrhoea and apparently typical histological changes.

    Background: Diabetic ketoacidosis (DKA) is an acute and life-threatening complication in diabetic patients. The current diagnostic criteria of DKA are metabolic acidosis, blood glucose level greater than 250 mg/dL and the presence of ketones in serum or urine. DKA patients referring to the emergency department (ED) are usually ill. Objectives: The present study aims to evaluate the efficacy of Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring in predicting the critically illness in the hyperglycemic patients referring to the ED. Patients and Methods: We performed a prospective cohort study in an ED. One hundred eighty one patients older than 18 years with hyperglycemia were included in our study. Following the primary evaluation, the subjects were divided into DKA and non-DKA patients. APACHE II scores were calculated for all patients and then compared to each other. We determined predictive value, sensitivity, specificity and cut-off points of APACHE II score for DKA. Results: Sixty two patients had DKA. The comparison of APACHE II score among two groups of the patients did not show any significant difference (P = 0.597). There was no suitable cut-off point for APACHE II score to predict DKA. Conclusions: APACHE II score cannot be applied in the predicting of DKA in hyperglycemic patients admitted in ED. PMID:25599026

    In an emergency department (ED), discharge communication represents a crucial step in medical care. In theory, it fosters patient satisfaction and adherence to medication, reduces anxiety, and ultimately promotes better outcomes. In practice, little is known about the extent to which patients receiving discharge information understand their medical condition and are able to memorize and retrieve instructions. Even less is known about the ideal content of these instructions. Focusing on patients with chest pain, we systematically assessed physicians' and patients' informational preferences and created a memory aid to support both the provision of information (physicians) and its retrieval (patients). In an iterative process, physicians of different specialties (N = 47) first chose which of 81 items to include in an ED discharge communication for patients with acute chest pain. A condensed list of 34 items was then presented to 51 such patients to gauge patients' preferences. Patients' and physicians' ratings of importance converged in 32 of the 34 items. Finally, three experts grouped the 34 items into five categories: (1) information on diagnosis; (2) follow-up suggestions; (3) advice on self-care; (4) red flags; and (5) complete treatment, from which we generated the mnemonic acronym "InFARcT." Defining and structuring the content of discharge information seems especially important for ED physicians and patients, as stress and time constraints jeopardize effective communication in this context. Chest pain accounts for up to 10% of all patient presentations in emergency departments (EDs) (Konkelberg & Esterman, 2003). The majority of these patients will usually be discharged within hours, after exclusion of serious conditions such as myocardial infarction (Goodacre et al., 2011). A comprehensive workup of low- to intermediate-risk patients is not feasible in the ED (Reichlin et al., 2009). Yet many of these patients go on to suffer from repeated episodes of chest

    Background: A number of bariatric surgical procedures have been developed to manage morbid obesity and related co-morbidities. The non-adjustable gastric band (NAGB) was one such procedure that created restriction to food intake by gastric segmentation. Benefits of the procedure included a low risk of perioperative complications and substantial early weight loss. Unfortunately, the long term results of NAGB include a high incidence of complications and failure to maintain weight loss. The purpose of this study was to examine the presentation, workup, and treatment of patients presenting with complications following NAGB placement. Methods: A retrospective review of the diagnosis and management of 11 patients who presented with complications related to NAGB placement. Results: All patients presented with some degree of proximal gastric outlet obstruction. The majority of patients (8/11) presented with vomiting as the main complaint. Other complaints included intolerance to solids, liquids, and reflux. Only 2/11 patients presented with weight loss since undergoing NAGB placement, while the remainder had weight regain to their pre-NAGB level and above. Depending on clinical presentation, desire for additional weight loss and co-morbid conditions, patients underwent a variety of treatments. This included NAGB removal (endoscopic, laparo-endoscopic, and laparoscopic) as well as conversion to another bariatric procedure (sleeve gastrectomy, Roux-en-Y gastric bypass). Conclusion: Patients with NAGB complications present with symptoms related to a proximal gastric outlet obstruction, related to constriction imposed by the band. This may result in severe food and liquid intolerance and subsequent weight loss, but more likely results in maladaptive eating and subsequent weight gain. Optimal therapy involves removal of the NAGB. Laparoscopic conversion to another bariatric procedure, optimally a Roux-en-Y gastric bypass, is warranted to treat morbid obesity and associated co

Odontogenic and nonodontogenic sources of orofacial pain should be considered and cranial neuralgias may be included in the differential diagnosis. Synchronous presentation of multiple cranial neuralgias is a rare occurrence. We report a case of a patient with a synchronous presentation of trigeminal, glossopharyngeal, and geniculate neuralgias. To our knowledge, this is the first case of a synchronous presentation of these conditions reported to date. PMID:27055735

    This case report presents the ophthalmic features and complications of a 56-year-old Caucasian woman with familial tumoral calcinosis. She presented to our ophthalmology clinic with a 3-month history of blurring of her vision. She had been diagnosed 14 years earlier with familial tumoral calcinosis. Ophthalmological examination revealed calcific depositions on the eyelid margins, perilimbal calcific deposits and angioid streaks. An optical coherence tomography scan of the left eye revealed a choroidal neovascular membrane. Deterioration in vision occurred secondary to subretinal haemorrhage, resulting from the angioid streak. The patient was treated with a series of three intravitreal ranibizumab injections to her left eye, which led to an improvement in her visual acuity (VA). The patient is being closely followed up with monthly appointments, and to date, after 6 months of follow-up, there has been no further deterioration in her VA or reactivation of the choroidal neovascular membrane.

    In an eight-year period (1983-1990) approximately 500 fine needle aspiration biopsies (FNABs) of eye lesions were processed in our laboratory. Eighty-one of the cases, obtained from 77 pediatric patients (ranging from 4 weeks to 16 years of age), were the subject of this study. The specimens included 73 intraocular and 8 orbital aspirates. Forty-four of the specimens were from diagnostic procedures, whereas 37 were obtained from surgical specimens immediately after enucleation. Eight FNABs (four diagnostic and four postenucleation) were deemed inadequate for cytologic diagnosis. Of the remaining 73 cases, 38 were diagnosed as malignant (34 retinoblastomas, 3 medulloepitheliomas, 1 rhabdomyosarcoma), and all were confirmed upon subsequent histologic examination. Four cases were diagnosed as suspicious for malignancy; all of them proved to be malignant (two retinoblastomas, two rhabdomyosarcomas). One orbital aspirate contained cells suggestive of a glial origin and was confirmed histologically as pilocytic astrocytoma. Ten cases were reported as compatible with Coats' disease; all were confirmed to be benign by histologic examination (three cases) or clinical follow-up (seven cases). The remaining 20 benign aspirates (13 with inflammatory cells, 6 with macrophages and 1 with blood) proved to be from benign conditions by histologic examination (4 cases) or clinical follow-up (16 cases). There were no false-positive diagnoses. The overall accuracy of FNAB was 95%, and the accuracy of cytologic interpretation was 100%. We conclude that FNAB is a reliable and accurate diagnostic modality in the assessment of selected pediatric ophthalmic diseases. PMID:8465629

    Contusions of the eyeball involve reactive or secondary changes in intraocular pressure. Clinical examinations of 151 patients with contusion disorders in ophthalmic tone revealed reactive hypertension in 6.62%, reactive hypotone in 31.79%, secondary hypertension in 48.34%, and stable hypotone of the injured eye in 15.89% cases. Secondary changes in intraocular pressure were caused by massive intraocular hemorrhages and structural injuries to the eyeball. The main cause of reactive hypotone resulting from blunt injury to the eye was exfusion, detachment of the vascular membrane diagnosed at that period by ultrasonic examination in 76.92% cases. The main factors responsible for the postcontusion reactive syndrome are changes occurring within a very short period of time, intraocular pressure differences, and "loss" of the threshold volume of the anterior chamber humor because of its discharge during the shock, and activation of the kallikrein-kinin system with release of kinins causing capillary dilatation and increasing capillary wall permeability in the presence of low activity of angiotensin-converting enzyme which destroys bradykinin.

    The purpose of the study was to determine the prevalence of ocular diseases in human immunodeficiency virus (HIV) patients in Washington, DC in the era of highly active antiretroviral therapy (HAART). This was a cross-sectional study of patients with HIV who were seen by the ophthalmology consultation service between September 2003 and May 2011 at a single academic institution in Washington, DC. Medical history and ophthalmic findings were reviewed. Patients with complete laboratory data dated within 3 months of their presenting eye examination were included. Descriptive statistics were performed. The records of 151 patients were included in the final analysis. All patients had complete laboratory data dated within 3 months of their presenting eye examination. Sixty-eight (45 %) patients and fifty-eight (50 %) of those with a diagnosis of acquired immune deficiency syndrome (AIDS) were diagnosed with an HIV-related ophthalmic disease. The leading anterior segment disease was herpes zoster ophthalmicus and the leading posterior segment disease was HIV retinopathy. Of the 151 included patients, 78 (52 %) were receiving HAART at the time of the examination. Thirty-one (42 %) of those not receiving HAART were diagnosed with an HIV-related ophthalmic disease. In this study, we find that the overall prevalence of ocular disease has decreased since the introduction of HAART. However, HIV patients continue to be predisposed to developing ophthalmic disease at higher rates than the general population. Visual dysfunction remains an important source of morbidity in HIV patients, particularly in those with AIDS. Measures for improvement include increased communication between infectious disease specialists and ophthalmologists to ensure adherence to HAART and routine eye examinations. PMID:22450559

    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

    Background: Delay in symptomatic presentation leading to advanced stage at diagnosis may contribute to poor cancer survival. To inform public health approaches to promoting early symptomatic presentation, we aimed to identify risk factors for delay in presentation across several cancers. Methods: We surveyed 2371 patients with 15 cancers about nature and duration of symptoms using a postal questionnaire. We calculated relative risks for delay in presentation (time from symptom onset to first presentation >3 months) by cancer, symptoms leading to diagnosis and reasons for putting off going to the doctor, controlling for age, sex and deprivation group. Results: Among 1999 cancer patients reporting symptoms, 21% delayed presentation for >3 months. Delay was associated with greater socioeconomic deprivation but not age or sex. Patients with prostate (44%) and rectal cancer (37%) were most likely to delay and patients with breast cancer least likely to delay (8%). Urinary difficulties, change of bowel habit, systemic symptoms (fatigue, weight loss and loss of appetite) and skin symptoms were all common and associated with delay. Overall, patients with bleeding symptoms were no more likely to delay presentation than patients who did not have bleeding symptoms. However, within the group of patients with bleeding symptoms, there were significant differences in risk of delay by source of bleeding: 35% of patients with rectal bleeding delayed presentation, but only 9% of patients with urinary bleeding. A lump was a common symptom but not associated with delay in presentation. Twenty-eight percent had not recognised their symptoms as serious and this was associated with a doubling in risk of delay. Embarrassment, worry about what the doctor might find, being too busy to go to the doctor and worry about wasting the doctor's time were also strong risk factors for delay, but were much less commonly reported (<6%). Interpretation: Approaches to promote early presentation should

    Viral infections in renal transplant patients are an important cause of morbidity and mortality. In most cases, the clinical presentation of herpes zoster allows the diagnosis to be made only by history and physical examination. However, patients who are immunosuppressed may have uncommon presentations, and require a high index of suspicion and additional diagnostic testing for proper management. We report a rare presentation of herpes zoster duplex bilateralis involving symmetrical dermatomes over the lower limbs occurring in a woman with a recent history of renal transplantation. The skin lesions were also atypical representing a diagnostic challenge. This infection should be part of differential diagnosis of cutaneous manifestations in organ transplant recipients.

    IgA nephropathy is the most common glomerulonephritis worldwide and typically has minimal signs for chronicity in histopathology at the time of initial presentation. Pseudotumor cerebri (PTC) is characterized by increased intracranial pressure in the absence of any intracranial lesions, inflammation, or obstruction. PTC has been reported in renal transplant and dialysis patients, but we are unaware of any reports of pseudotumor cerebri in patients with IgA nephropathy. We report a case of a young female who presented with signs and symptoms of pseudotumor cerebri and was subsequently diagnosed with IgA nephropathy and end-stage renal disease. To our knowledge this is the first report of IgA nephropathy presenting as end-stage renal disease in a patient who presented with pseudotumor cerebri. PMID:26989531

    Orbital metastasis is uncommon and occurs in 2–3% of patients with cancer. It is rarely the initial manifestation of a systemic malignancy. It usually indicates extensive haematogenous dissemination of a primary cancer and is associated with poor prognosis. Breast, lungs and prostate cancers are the most common primary cancers leading to orbital metastasis. However, orbital tumour revealing a rectal adenocarcinoma is exceptional. We describe a case of orbital tumour in a 67-year-old man with no history of systemic cancer while presenting with ophthalmic symptoms. Investigations revealed rectal adenocarcinoma as the primary malignant tumour. PMID:24481014

    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

    Objectives: The primary purpose of this study was to determine the level of agitation that psychiatric patients exhibit upon arrival to the emergency department. The secondary purpose was to determine whether the level of agitation changed over time depending upon whether the patient was restrained or unrestrained. Method: An observational study enrolling a convenience sample of 100 patients presenting with a psychiatric complaint was planned, in order to obtain 50 chemically and/or physically restrained and 50 unrestrained patients. The study was performed in summer 2004 in a community, inner-city, level 1 emergency department with 45,000 visits per year. The level of patient agitation was measured using the Agitated Behavior Scale (ABS) and the Richmond Agitation-Sedation Scale (RASS) upon arrival and every 30 minutes over a 3-hour period. The inclusion criteria allowed entry of any patient who presented to the emergency department with a psychiatric complaint thought to be unrelated to physical illness. Patients who were restrained for nonbehavioral reasons or were medically unstable were excluded. Results: 101 patients were enrolled in the study. Of that total, 53 patients were not restrained, 47 patients were restrained, and 1 had incomplete data. There were no differences in gender, race, or age between the 2 groups. Upon arrival, 2 of the 47 restrained patients were rated severely agitated on the ABS, and 13 of 47 restrained patients were rated combative on the RASS. There was a statistical difference (p = .01) between the groups on both scales from time 0 to time 90 minutes. Scores on the agitation scales decreased over time in both groups. One patient in the unrestrained group became unarousable during treatment. Conclusion: This study demonstrated that patients who were restrained were more agitated than those who were not, and that agitation levels in both groups decreased over time. Some restrained patients did not meet combativeness or severe agitation

    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

    The management of low-risk patients presenting to emergency departments is a common and challenging clinical problem entailing 8 million emergency department visits annually. Although a majority of these patients do not have a life-threatening condition, the clinician must distinguish between those who require urgent treatment of a serious problem and those with more benign entities who do not require admission. Inadvertent discharge of patients with acute coronary syndrome from the emergency department is associated with increased mortality and liability, whereas inappropriate admission of patients without serious disease is neither indicated nor cost-effective. Clinical judgment and basic clinical tools (history, physical examination, and electrocardiogram) remain primary in meeting this challenge and affording early identification of low-risk patients with chest pain. Additionally, established and newer diagnostic methods have extended clinicians' diagnostic capacity in this setting. Low-risk patients presenting with chest pain are increasingly managed in chest pain units in which accelerated diagnostic protocols are performed, comprising serial electrocardiograms and cardiac injury markers to exclude acute coronary syndrome. Patients with negative findings usually complete the accelerated diagnostic protocol with a confirmatory test to exclude ischemia. This is typically an exercise treadmill test or a cardiac imaging study if the exercise treadmill test is not applicable. Rest myocardial perfusion imaging has assumed an important role in this setting. Computed tomography coronary angiography has also shown promise in this setting. A negative accelerated diagnostic protocol evaluation allows discharge, whereas patients with positive findings are admitted. This approach has been found to be safe, accurate, and cost-effective in low-risk patients presenting with chest pain. PMID:20660809

    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

    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

    Ebstein's anomaly is a common congenital abnormality in the Wolff-Parkinson white syndrome (WPW). The term WPW is applied to patients with both preexcitation on ECG and paroxysmal tachycardias. In this case review, we describe a female with a history of intermittent palpitations who presented in the postpartum period with WPW. Subsequent testing revealed an underlying Ebstein's anomaly. In the United States, heart disease is responsible for 10% of maternal deaths. Although pregnancy is well known to exacerbate symptoms in patients with WPW, postpartum exacerbation has not been clearly described. This unusual case suggests that monitoring beyond the peurperium would be advisable in patients at risk to develop malignant tachyarrhythmias. PMID:12852798

    Introduction: Extramedullary hematopoiesis in the kidney and adrenal are rarely reported in medical literature and are usually found as incidentaloma. It usually occurs in patients with hematologic disorder such as thalassemia. Case Presentation: The patient was a 23-year-old Iranian man with beta thalassemia who was admitted with a suprarenal mass. Adrenal mass was detected by ultrasonography and computed tomography. Results of biochemical evaluations were insignificant. The patient underwent right adrenalectomy. Gross and microscopic histopathologic examination demonstrated extramedullary hematopoiesis without any adrenal tissue. Conclusions: To the best of our knowledge, we document the first reported case of adrenal extramedullary hematopoiesis in Iran, which seems to be rare and remarkable. PMID:25695031

    This study investigated the interaction between polydeoxyribonucleotide (PDRN) and several ionic and nonionic isotonic agents, thickeners and a preservative that were employed as excipients in ophthalmic preparations. Interaction of each individual excipient and PDRN aqueous solution was evaluated by analyzing their rheological properties. Rheological properties of PDRN solutions were evaluated by dynamic oscillatory shear tests and values of elastic modulus (G'), viscous modulus (G″) and loss tangent (tan δ) were used to assess the relative changes in viscoelastic properties. At given concentrations, sodium chloride was found to show alteration in viscoelastic properties of PDRN solution while nonionic isotonic agents like d-glucose and d-sorbitol did not alter them. Similarly, nonionic water soluble polymers like polyvinylpyrrolidone (PVP) and hydroxypropyl methylcellulose (HPMC) also did not interact with PDRN to alter the viscoelastic properties. However, there were changes observed when carbopol 940 was used as a thickener. Therefore, PDRN was found to interact with ionic excipients and the interactions were negligible when nonionic materials were examined, which suggests that nonionic excipients are suitable to be formulated with PDRN.

    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.

    Eating disorders (EDs) have been underdiagnosed in many clinical settings. This study investigates the influence of clinical characteristics on presenting symptoms of patients with EDs. Psychiatric outpatients, aged 18-45, were enrolled sequentially and received a two-phase survey for EDs in August 2010-January 2013. Their primary reasons for seeking psychiatric help were obtained at their first encounter with outpatient psychiatrists. Patients' clinical and demographic characteristics were compared according to presenting symptoms with or without eating/weight problems. Of 2140 patients, 348 (16.3%) were diagnosed with an ED (22.6% of women and 6.3% of men). The three most common reasons for seeking psychiatric help were eating/weight problems (46.0%), emotional problems (41.3%), and sleep disturbances (19.3%). The multivariate analyses suggest that when patients with EDs presented symptoms that were less related to eating/weight problems, they were significantly more likely to be those having diagnoses other than anorexia nervosa or bulimia nervosa and less severe degree of binge-eating. Further, patients with EDs who demonstrated more impulsive behaviors and poorer functioning were less likely to report their eating problems when visiting psychiatric clinics. Thus, ED should be assessed routinely in patients with complex psychopathology to facilitate comprehensive treatment. PMID:27086254

    Importance Patients with stable coronary artery disease (CAD) attribute greater benefit to percutaneous coronary interventions (PCI) than indicated in clinical trials. Little is known about how cardiologists' presentation of the benefits and risks may influence patients' perceptions. Objectives To broadly describe the content of discussions between patients and cardiologists regarding angiogram and PCI for stable CAD, and to describe elements that may affect patients' understanding. Design, Setting, and Participants Qualitative content analysis of encounters between cardiologists and patients with stable CAD who participated in the Verilogue Point-of-Practice Database between March 1, 2008, and August 31, 2012. Transcripts in which angiogram and PCI were discussed were retrieved from the database. Patients were aged 44 to 88 years (median, 64 years); 25% were women; 50% reported symptoms of angina; and 6% were taking more than 1 medication to treat angina. Main Outcomes and Measures Results of conventional and directed qualitative content analysis. Results Forty encounters were analyzed. Five major categories and subcategories of factors that may affect patients' understanding of benefit were identified: (1) rationale for recommending angiogram and PCI (eg, stress test results, symptoms, and cardiologist's preferences); (2) discussion of benefits (eg, accurate discussion of benefit [5%], explicitly overstated benefit [13%], and implicitly overstated benefit [35%]); (3) discussion of risks (eg, minimization of risk); (4) cardiologist's communication style (eg, humor, teach-back, message framing, and failure to respond to patient questions); and (5) patient and family member contributions to the discussion. Conclusions and Relevance Few cardiologists discussed the evidence-based benefits of angiogram and PCI for stable CAD, and some implicitly or explicitly overstated the benefits. The etiology of patient misunderstanding is likely multifactorial, but if future

    Investigations of left hand praxis in imitation and object use in patients with callosal disconnection have yielded divergent results, inducing a debate between two theoretical positions. Whereas Liepmann suggested that the left hemisphere is motor dominant, others maintain that both hemispheres have equal motor competences and propose that left hand apraxia in patients with callosal disconnection is secondary to left hemispheric specialization for language or other task modalities. The present study aims to gain further insight into the motor competence of the right hemisphere by investigating pantomime of object use in split-brain patients. Three patients with complete callosotomy and, as control groups, five patients with partial callosotomy and nine healthy subjects were examined for their ability to pantomime object use to visual object presentation and demonstrate object manipulation. In each condition, 11 objects were presented to the subjects who pantomimed or demonstrated the object use with either hand. In addition, six object pairs were presented to test bimanual coordination. Two independent raters evaluated the videotaped movement demonstrations. While object use demonstrations were perfect in all three groups, the split-brain patients displayed apraxic errors only with their left hands in the pantomime condition. The movement analysis of concept and execution errors included the examination of ipsilateral versus contralateral motor control. As the right hand/left hemisphere performances demonstrated retrieval of the correct movement concepts, concept errors by the left hand were taken as evidence for right hemisphere control. Several types of execution errors reflected a lack of distal motor control indicating the use of ipsilateral pathways. While one split-brain patient controlled his left hand predominantly by ipsilateral pathways in the pantomime condition, the error profile in the other two split-brain patients suggested that the right hemisphere

    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

    Ophthalmic Graves' disease and histiocytosis X involving the orbit are occasionally refractory to treatment, so that vision may be threatened. In these situations megavoltage external beam radiotherapy should be employed, and the indications for this treatment are discussed. A highly accurate technique is described, using precise planning with information obtained from high definition CT scans, a complete patient head shell for immobilisation, and modern megavoltage radiotherapy treatment machines. As a result the dose to the lens is minimised (to a maximum of 10% of the prescribed dose), and late morbidity will be small. Two cases are described to illustrate this procedure and the response to treatment. Images PMID:3259894

    Selective ophthalmic artery infusion chemotherapy (SOAIC) is increasingly used to treat retinoblastoma. We report the toxicities and outcome of 19 eyes in 17 patients with retinoblastoma receiving SOAIC treatment between 2008 and 2013. From the 87 treatments, mild local reactions were common. Myelosuppression was more common after triple-agent SOAIC (melphalan, carboplatin, and topotecan) than single-agent melphalan. Ocular salvage was achieved in 11 of 19 eyes and associated with triple-agent therapy. SOAIC is a effective therapy for some retinoblastoma with manageable toxicity; however, systemic toxicity increases with increasing therapeutic intensity of SOAIC. PMID:26583615

    Polymyalgia rheumatica is an inflammatory rheumatic disease that presents with bilateral pain and stiffness affecting mainly proximal muscles. It affects individuals over 50 years of age and it is usually associated with a raised erythrocyte sedimentation rate. Classically, treatment with low-dose corticosteroids results in a dramatic improvement in both symptoms and laboratory findings. We report the case of an 80 years old patient presenting polymyalgia rheumatica coinciding with pleuropericardial effusion. The patient had a very good response to treatment with rapid improvement in the symptomatology and laboratory findings. Polymyalgia Rheumatica is a common disease but it is rarely associated to pleuropericardial effusion. It should be considered in the differential diagnostic in patients presenting with pericardial effusion over 50 of age years due to the good response to treatment. PMID:23453662

    The objective of the present work was to highlight and systematize the current scientific concepts of the role of psychological factors in the psycho-social adaptation of the patients presenting the Meniere's disease. The authors analysed the data concerning the psycho-social adaptation of the patients presenting with this condition that were published in the scientific literature during many years. The detailed analysis of the psychological characteristics of the patients allowed to reveal peculiarities of their psychological response to the disease and conserved personal-environmental resources that can be used in the development of stress-adaptation models for the psychological correction and psychotherapeutic treatment with a view to their subsequent introduction into the routine clinical practice of healthcare service institutions.

    Tuberculosis is a healthcare concern that affects millions of individuals around the globe. Coinfection with HIV has changed both the clinical presentation and the outcome of the disease dramatically in the last few decades. Extrapulmonary tuberculosis is seen more frequently in the immunocompromised host. An unusual case of gastric tuberculosis in an AIDS patient is reported here. A 49-year-old female with AIDS was admitted for fever and epigastric pain. A gastric submucosal abscess was observed on imaging and confirmed by biopsy showing numerous neutrophils and acid-fast bacilli. Aspirate grew Mycobacterium tuberculosis. This report highlights a very unusual presentation of tuberculosis in an immunodeficient patient. High clinical suspicion for opportunistic infections in unusual locations should be maintained in these patients presenting with clinical syndromes that do not respond to standard treatments. New diagnostic modalities facilitate accurate identification of these infections. PMID:27239353

    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.

    Thirty-five patients who presented with chest pain underwent mapping of the ECG with exercise and angiocardiography. Krypton-81m was used to assess regional myocardial perfusion before, during and after atrial pacing. Twelve of the 35 patients had negative exercise tests. Eight of these 12 had normal coronary arteries and four had less than or equal to 50% stenosis of at least one major coronary artery. All 12 patients had uniform increases in regional myocardial perfusion (98 plus/minus 14.0%) during atrial pacing. Thirteen of the 35 patients had a history of myocardial infarction and precordial areas of Q waves. During exercise, all 13 patients complained of chest pain and showed precordial areas of both ST-segment elevation and depression. These 13 patients had greater than or equal to 70% stenosis of at least one major coronary artery. Myocardial blood flow studies showed fixed defects of perfusion corresponding to the Q waves and ST-segment elevation. In addition, there were separate transient decreases of regional myocardial perfusion (70 plus/minus 9.0%) during atrial pacing corresponding to ST-segment depression and chest pain. Ten of the 35 patients had a history of myocardial infarction and precordial areas of Q waves. These areas showed no changes during atrial pacing. All the patients showed at least one remote region of myocardium that increased perfusion (74 plus/minus 170%) throughout pacing. Patients with a history of myocardial infarction may present with chest pain. In this study, ST-segment elevation during an exercise ECG was not associated with chest pain or detectable myocardial ischemia. Regional perfusion in infarcted segments of myocardium did not change with atrial pacing.

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.

    Background& Aims There is not much data available about the prevalence or effects of cirrhosis in patients with hepatocellular carcinoma (HCC) from viral hepatitis. We compared patients with HCC and hepatitis B virus (HBV) or hepatitis C virus (HCV) infections to determine the proportions of cirrhosis in each group, virologic and tumor characteristics, and overall survival. Methods This analysis includes patients with HBV (n=64) or HCV (n=118) infection who were diagnosed with HCC at the Mayo Clinic in Rochester MN from 1994 to 2008; groups were matched for age and sex. The diagnosis of cirrhosis was based on histology and, if histologic information was insufficient or unavailable, clinical indicators that included ascites or varices, thrombocytopenia or splenomegaly, and radiographic configuration of cirrhosis. Virologic characteristics, tumor stage, and patient survival were also assessed. Results The prevalence of histologic cirrhosis was 88% among patients with HBV infection and 93% among those with HCV infection (P=0.46). When the most inclusive criteria for cirrhosis were applied, cirrhosis was present in 94% of patients with HBV and 97% with HCV (P=0.24). Among HCV patients, 5.2% were negative for HCV RNA following antiviral treatment; 63.4% of HBV patients had HBV DNA < 2000 u/ml with or without treatment. Patients with HBV tended to have less surveillance and more advanced stages of HCC, without differences in survival from those with HCV infection (P=0.75). Conclusion Most patients with HCC and chronic viral hepatitis had evidence of cirrhosis, including those with HBV infection and those without active viral replication. PMID:20831903

    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.

    Clinical heterogeneity is the prominent feature of spinocerebellar ataxia type 3 (SCA3) which is sometimes neglected and often impedes the timely diagnosis of patients. In this study, the clinical data of 201 unrelated Chinese SCA3 patients were retrospectively studied. The rare clinical features were summarized and the underlying genetic mutations were screened by direct DNA sequencing. Three patients were found primarily presenting with the rare clinical features, including dystonic phenotype without response to levodopa, chorea and memory decline, and hearing impairment, respectively. We firstly reported three diverse heterogeneities of SCA3 patients, which are quite uncommon in the Chinese SCA3 patients. Our results expanded the variable phenotypes of SCA3 and provided the explicit information for the rare and special SCA3 manifestations. Based on this new knowledge, we suggested that when the presentation was consistent with HD or DRD while negative in the corresponding genetic testing, SCA3 should be considered, and clinicians should divert partial attention to the examinations on the auditory system of SCA3 patients.

    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

    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.

    Cimetidine, a H(2) receptor antagonist, has been reported to improve survival in gastrointestinal cancer patients. These effects have largely been attributed to the enhancing effects of cimetidine on the host's antitumour cell-mediated immune response, such as inhibition of suppressor T lymphocyte activity, stimulation of natural killer cell activity and increase of interleukin-2 production from helper T lymphocytes. We conducted an in vitro study on the effects of cimetidine on differentiation and antigen presenting capacity of monocyte-derived dendritic cells from advanced colorectal cancer patients and normal controls. As a result, an investigation of expression of surface molecules associated with dendritic cells by flow cytometric analyses showed that cimetidine had no enhancing effect on differentiation of dendritic cells from cancer patients and normal controls. An investigation of [(3)H]thymidine incorporation by allogeneic mixed lymphocyte reactions revealed that cimetidine increased the antigen presenting capacity of dendritic cells from both materials. Moreover, a higher antigen presenting capacity was observed in advanced cancer patients compared to normal controls. These effects might be mediated via specific action of cimetidine and not via H(2) receptors because famotidine did not show similar effects. Our results suggest that cimetidine may enhance the host's antitumour cell-mediated immunity by improving the suppressed dendritic cells function of advanced cancer patients. PMID:11953882

    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

    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.

    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.

    Topical route of administration is the most commonly used method for the treatment of ophthalmic diseases. However, presence of several layers of permeation barriers starting from the tear film till the inner layers of cornea make it difficult to achieve the therapeutic concentrations in the target tissue within the eye. In order to circumvent these barriers and to provide sustained and targeted drug delivery, tremendous advances have been made in developing efficient and safe drug delivery systems. Liposomes due to their unique structure prove to be extremely beneficial drug carriers as they can entrap both the hydrophilic and hydrophobic drugs. The conventional liposomes had several drawbacks particularly their tendency to aggregate, the instability and leakage of entrapped drug and susceptibility to phagocytosis. Due to this reason, for a long time, liposomes as drug delivery systems did not attract much attention of researchers and clinicians. However, over recent years development of new generation liposomes has opened up new approaches for targeted and sustained drug delivery using liposomes and has rejuvenated the interest of researchers in this field. In this review we present a summary of current literature to understand the anatomical and physiological limitation in achieving adequate ocular bioavailability of topically applied drugs and utility of liposomes in overcoming these limitations. The recent developments related to new generation liposomes are discussed. PMID:25116511

    Histoplasmosis is a progressive disease caused by dimorphic intracellular fungi and can prove fatal. Usually, it is present in immunocompromised individuals and immunocompetent individuals in the endemic zones. We report an unusual presentation of progressive disseminated histoplasmosis. The patient in the present case report was immunocompetent child and had fever, bone pains, gradual weight loss, lymphadenopathy and hepatosplenomegaly. Disseminated histoplasmosis (DH) was diagnosed on microscopic examination and fungal culture of bone marrow, blood, skin biopsy and lymph node aspirate. The patient died on seventh day of amphotericin B. In the absence of predisposing factors and classical clinical presentation of febrile neutropenia, lung, adrenal and oropharyngeal lesions, the disease posed a diagnostic challenge. Progressive disseminated histoplasmosis in children can be fatal despite timely diagnosis and therapy. In India, disseminated histoplasmosis is seen in immunocompetent hosts. All the pediatrics immunocompetent cases from India are also reviewed. PMID:26126955

    Introduction: Giant cell tumor is a locally aggressive benign tumor. Giant cell tumor of bone is characteristically found in skeletally mature patient at the end of long bones in the epiphyseal region or epiphysio-metaphyseal region. Giant cell tumor is very rare in skeletally immature patient. But we are presenting a very rare case of giant cell tumor in skeletally immature patient in diaphyseal region which is very uncommon location for giant cell tumor. From this case we concluded that irrespective of the location and skeletal maturity, a giant cell tumor should be diagnosed based on its histology because classical clinical-radiological features are not always present. Index case strengthens this view. PMID:27299037

    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. PMID:26977564

    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.

    Ultrasonography has been proposed as the initial test for detection of bladder carcinomas in patients presenting with hematuria, but the accuracy of transabdominal ultrasonography in the diagnosis of superficial bladder carcinoma has not been assessed. We prospectively evaluated 173 patients presenting to the outpatient department with painless hematuria by transabdominal ultrasound and cystoscopy. The tolerability of cystoscopy was also assessed. Of 148 patients who met the inclusion criteria, 39 with bladder carcinoma were identified by cystoscopy as having bladder carcinoma, while 34 were identified by ultrasonography. For ultrasonography, the sensitivity (87.1%), specificity (98.1%), positive predictive value (94.4%) and negative predictive value (95.4%) were good but not as good as cystoscopy. While the tolerability of cystoscopy is relatively low, it is still superior to ultrasonography in the evaluation of the bladder as a possible source of hematuria. PMID:19318748

    Background There is strong evidence that delayed diagnosis of breast cancer is associated with poor survival. The objectives were to determine the frequency of breast cancer patients with delayed presentation, the reasons of delay and its association with different socio-demographic variables in our settings. Methods We interviewed 315 histologically confirmed breast cancer patients. Delay was defined as more than 3 months from appearance of symptoms to the consultation from doctor. Questions were asked from each patient which could reflect their understanding about the disease and which could be the likely reasons for their delayed presentation. Results A total of 39.01% (n=123) of patients presented late and out of those, 40.7% wasted time using alternative medicines; 25.2% were not having enough resources; 17.1% presented late due to painless lump; 10.6% felt shyness and 6.5% presented late due to other reasons. Higher age, negative family history, <8 school years of education and low to middle socio-economic status were significantly associated with delayed presentation (P<0.05). Education and socioeconomic status were two independent variables related to the delayed presentation after adjustment for others [odds ratios (OR) of 2.26, 2.29 and 95% confidence intervals (CI) was 1.25-4.10, 1.06-4.94 respectively]. Conclusions Significant percentage of women with breast cancer in North Pakistan is experiencing presentation delay due to their misconceptions about the disease. Coordinated efforts with public health department are needed to educate the focused groups and mitigating the barriers identified in the study. Long term impact will be reduced overall burden of the disease in the region. PMID:26157325

    Image resolution, tissue penetration, and scan speed are among the most important parameters when designing an OCT system for ophthalmic use. Human retinal tissue is highly reflective in the near infrared spectrum range. A SLD at 820nm with 25nm FWHM spectral bandwidth provides 10μm coherence length in retinal tissue. Its appropriate power level, simplicity of use, high resolution, and relatively low cost, make the 820nm SLD the best choice light source for retinal OCT. A 1300nm SLD can penetrate deeper into the sclera tissue and since the 1300nm wavelength is highly absorbed in the vitreous, the ANSI laser safety standard allows higher maximum permissible power to the human eye. Higher scan speed can also be achieved. In this paper, we report two OCT systems that are designed specifically for retinal and anterior segment imaging of the human eye. Retinal OCT scans 400 A-scans per second, 2mm depth in tissue, and 10 μm image resolution with an 820nm SLD. Anterior segment OCT (AC-OCT) scans 2000 A-scans per second, 6mm depth in tissue, and 16μm image resolution with a 1300nm SLD. Benefits of suitable wavelength selection in scanning different tissue are clearly seen in the OCT images. Retinal OCT (OCT3) demonstrates significant improvement over the previous generation (OCT1/OCT2) from both a technical and cost point of view. AC-OCT performs 8 frames of 256 A-scans per second and is capable of imaging the human eye in vivo with minimum eye motion artifacts. It has potential use in refractive surgery, angle-closure glaucoma, and cataract surgery.

    Toxoplasma gondii is an opportunistic infection that often presents in the setting of acquired immunodeficiency syndrome. The infection can cause severe and potentially fatal encephalitis because of the reactivation of latent infections in the setting of immune suppression. Diagnosing toxoplasmosis encephalitis (TE) in immunocompromised patients often is difficult because the signs and symptoms can be nonspecific, but making a diagnosis of TE is even more challenging in a patient who is not known to have human immunodeficiency virus/acquired immunodeficiency syndrome and shows no other signs of being immunocompromised. Early diagnosis and treatment can result in rapid radiologic and clinical improvement; however, no studies exist that evaluate the utility of functional rehabilitation for patients diagnosed with TE. Although previous studies report a good prognosis for patients who receive antibiotic treatment, they do not discuss the extent to which functional abilities lost during the infection are returned after their treatment. We discuss a case of stroke-like presentation of cerebral TE in a patient whose human immunodeficiency virus status was previously unknown and report the functional improvements that were made during acute inpatient rehabilitation.

    Blood stasis (BS) is characterized as a disorder of blood circulation. In traditional Korean medicine (TKM), it is viewed as a cause factor of diseases such as multiple sclerosis and stroke. This study investigated differences in the plasma metabolites profiles of subjects displaying BS or non-BS patterns. Thirty-one patients with cerebral infarction diagnosed with BS and an equal number of sex- and age-matched non-BS patients were enrolled. Metabolic profiling was performed using UPLC-MS. The ratio of subjects with a rough pulse and purple coloration of the tongue was higher in patients presenting with BS pattern. Through metabolomics analysis, 82 metabolites that differed significantly between the BS and non-BS pattern were identified, and the two groups were significantly separated using an orthogonal partial least square-discriminant analysis model (P < 0.001). Of these 82 metabolites, acetyl carnitine, leucine, kynurenine, phosphocholine, hexanoyl carnitine, and decanoyl carnitine were present in significantly higher levels in patients with a BS pattern than those with a non-BS pattern. Our results also demonstrated that seven plasma metabolites, including acyl-carnitines and kynurenine, were associated with a BS pattern, suggesting that variant plasma metabolic profiles may serve as a biomarker for diagnosis of BS in patients with cerebral infarction.

    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.

    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

    2016-01-01

    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 of a possible association with high BMI. PMID:27363628

    This report discusses the following: the optical radiation emitted by a variety of ophthalmic instruments were measured and compared to current safety standards. In addition, a survey of clinical diagnostic examination times was conducted to compare exposure safe times to visible lesion threshold. It was demonstrated that excessive levels of ultraviolet (UV) and infrared (IR) radiation could be emitted and should be eliminated. Several of the instruments emitted levels of visible radiation that resulted in very short safe times and could exceed the visible lesion threshold. Four experiments demonstrated instrument operating conditions that would reduce the potential for ocular hazards from ophthalmic instruments.

    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.

    We report 4 cases of apparent ophthalmic ointment in the anterior chamber after sutureless clear corneal phacoemulsification and posterior chamber intraocular lens implantation. The cases, as well as previous literature, indicate that ointment for topical use can be well tolerated in the eye, although glaucoma and uveitis can be potential negative outcomes. Possible risk factors, some of which may be related to current rates of endophthalmitis after clear corneal cataract surgery, and methods to prevent intraocular ophthalmic ointment after cataract surgery are discussed.

    Objective: To see the various clinical presentations and biochemical profile in adult celiac disease patients of Hyderabad Sindh. Methods: A total 60 suspected cases of adult celiac disease, both males and females were screened out from Liaquat University of Medical and Health Sciences hospital and private clinics at Sadar Hyderabad Sind by non probability purposive sampling during a period from July 2011 to December 2012.Age ranged between 18 to 55 Years. A detailed history and clinical examination was done. Patients already on gluten free diet, age <12years, tuberculosis or cancer of intestine/colon and patients of diabetes and thyroid disorder were excluded, while patients having positive ant tTG (value >15 iu/ml detected by ELISA) were included. The biochemical profile including serum albumin, calcium ,ferritin, SGPT, Alkaline phosphatase and Haemoglobin were estimated in central Diagnostic laboratory LUMHS by taking 10 cc centrifuged blood sample. The data was plotted on SPSS 16, mean and percentages were calculated. Results: All patients were divided in to three groups according to age. The most common group was 18-30 years; (mean, 23.5±5.6) comprised 56.6%. The commonest clinical presentation was diarrhoea in 50%, menstrual irregularity in 21%, walking problems 21%, undue fatigue in 15% and edema in 15%. P values calculated in quantitative variable of males and females. The p value was significant in between serum calcium (p 0.004), haemoglobin (p 0,004), serum ferritin (<0.005) and alkaline phosphatise (<0.005). Conclusion: This study showed that Adult celiac disease was present with entirely different clinical and biochemical profile in patients in this region. PMID:24772128

    Abstract 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. PMID:26844519

    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.

    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.

    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.

    We investigated the possible existence of endogenous compounds acting on benzodiazepine central receptors in the serum of patients with panic attacks or depression. Our results show the presence of a substance which inhibits the 3H-flunitrazepam binding specifically in the samples taken from the patients' groups, and which is not present in normal controls, in the range of concentrations used. This compound has a molecular weight below 1,000 daltons, is heat-stable, and resistant to proteolytic degradation. The demonstration of this inhibitor opens new perspectives in the study of the biochemistry of anxiety. PMID:2836759

    Background and Purpose The occurrence of PWD in neurodegenerative disease is very rare, and this is the first report of it being related to early-onset AD. We describe a patient with early-onset Alzheimer's disease (AD) who presented with pure word deafness (PWD). Case Report The patient had experienced PWD for 2 years, followed by other cognitive deficits suggestive of parietotemporal dysfunction. Brain imaging including 18FDG-PET and [11C] PIB-PET supported the diagnosis of AD. Conclusions Our case highlights the clinical variability that characterizes early-onset AD. PMID:22259620

    Postherpetic neuralgia is one of the most common, but also one of the most difficult conditions to treat. This condition mainly involves trigeminal, intercostal and sciatic nerves and the brachial plexus area. It mostly appears in patients older than 60 years. Although pain is a transient condition, the pain of postherpeutic neuralgia may become intractable, disabling an may decrease the quality of the patient's life. We studied 30 patients affected by ophthalmic postherpetic neuralgia, appearing, some months after fronto-orbital cutaneous eruption. All patients received nicardipine retard, decreasing gradually, 40 mg/day for 2 weeks. The monitoring of pain was performed using the visual analogue score of Scott-Huskissonn. The results show an improvement in 'pain relief'. PMID:8570150

    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.

    The authors present an unusual case of an acute swelling of the lower lip and septicemia in a 35-year-old, recent immigrant male arriving from India. The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region. PMID:22677026

    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

    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

    2016-01-01

    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

  3. Balancing the presentation of information and options in patient decision aids: an updated review

    PubMed Central

    2013-01-01

    Background Standards for patient decision aids require that information and options be presented in a balanced manner; this requirement is based on the argument that balanced presentation is essential to foster informed decision making. If information is presented in an incomplete/non-neutral manner, it can stimulate cognitive biases that can unduly affect individuals’ knowledge, perceptions of risks and benefits, and, ultimately, preferences. However, there is little clarity about what constitutes balance, and how it can be determined and enhanced. We conducted a literature review to examine the theoretical and empirical evidence related to balancing the presentation of information and options. Methods A literature search related to patient decision aids and balance was conducted on Medline, using MeSH terms and PubMed; this search supplemented the 2011 Cochrane Collaboration’s review of patient decision aids trials. Only English language articles relevant to patient decision making and addressing the balance of information and options were included. All members of the team independently screened clusters of articles; uncertainties were resolved by seeking review by another member. The team then worked in sub-groups to extract and synthesise data on theory, definitions, and evidence reported in these studies. Results A total of 40 articles met the inclusion criteria. Of these, six explained the rationale for balancing the presentation of information and options. Twelve defined “balance”; the definition of “balance” that emerged is as follows: “The complete and unbiased presentation of the relevant options and the information about those options—in content and in format—in a way that enables individuals to process this information without bias”. Ten of the 40 articles reported assessing the balance of the relevant decision aid. All 10 did so exclusively from the users’ or patients’ perspective, using a five-point Likert-type scale

    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

    Obsessionality and obsessive-compulsive symptoms have been regarded as important characteristics in the clinical presentation of the eating disorders. In this report, we examined the relation between obsessionality and the clinical presentation and outcome of a sample of eating-disordered patients. Self-rated obsessional symptoms, defined by the obsessive-compulsive subscale of the Symptom Checklist 90 (revised version), were compared with presenting clinical symptomatology, and scores on the Eating Disorder Inventory (EDI) and Beck Depression Inventory (BDI) in a sample of 110 consecutively evaluated women who met DSM-IIIR criteria for eating disorders. Forty patients were contacted for a follow-up investigation, 2 years after the initial evaluation. Higher obsessive-compulsive subscale scores at presentation were associated with more severe dieting, a greater number of psychiatric hospitalizations, and higher EDI, SCL-90R and BDI scores. Initial obsessive-compulsive scores did not predict the subsequent outcome of a sample of these patients in the community. However, elevated obsessive-compulsive scores obtained at follow-up were associated with the presence of lower body weight and more severe eating-disorder symptoms at that time. These results support the hypothesis that elevated obsessionality is associated with more severe eating disorder symptomatology. In addition, obsessional symptoms change along with those of the eating disorder, and their persistence may be associated with a poorer outcome. PMID:8847659

    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 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

    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

    Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH) patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 – 21). Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes) were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation. PMID:23226638

    2008-01-01

    Background Musculoskeletal problems generate high costs. Of these disorders, patients with knee problems are commonly seen by GPs. Magnetic resonance imaging (MRI) of the knee is an accurate diagnostic test, but there is uncertainty as to whether GP access to MRI for these patients is a cost-effective policy. Aim To investigate the cost-effectiveness of GP referral to early MRI and a provisional orthopaedic appointment, compared with referral to an orthopaedic specialist without prior MRI for patients with continuing knee problems. Design of study Cost-effectiveness analysis alongside a pragmatic randomised trial. Setting Five-hundred and thirty-three patients consulting their GP about a knee problem were recruited from 163 general practices at 11 sites across the UK. Method Two-year costs were estimated from the NHS perspective. Health outcomes were expressed in terms of quality-adjusted life years (QALYs), based on patient responses to the EQ–5D questionnaire administered at baseline, and at 6, 12, and 24 months' follow-up. Results Early MRI is associated with a higher NHS cost, by £294 ($581; €435) per patient (95% confidence interval [CI] = £31 to £573), and a larger number of QALYs, by 0.05 (95% CI = 0.025 to 0.118). Mean differences in cost and QALYs generated an incremental cost per QALY gained of £5840 ($11 538; €8642). At a cost per QALY threshold of £20 000, there is a 0.81 probability that early MRI is a cost-effective use of NHS resources. Conclusion GP access to MRI for patients presenting in primary care with a continuing knee problem represents a cost-effective use of health service resources. PMID:19000394

    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

    Purpose: To determine whether the computed dosimetry of a new ophthalmic plaque, EP917, when compared with the standard Collaborative Ocular Melanoma Study (COMS) plaques, could reduce radiation exposure to vision critical structures of the eye. Methods and Materials: One hundred consecutive patients with uveal melanoma treated with COMS radiation plaques between 2007 and 2010 were included in this study. These treatment plans were generated with the use of Bebig Plaque Simulator treatment-planning software, both for COMS plaques and for EP917 plaques using I-125. Dose distributions were calculated for a prescription of 85 Gy to the tumor apex. Doses to the optic disc, opposite retina, lens, and macula were obtained, and differences between the 2 groups were analyzed by standard parametric methods. Results: When compared with the COMS plaques, the EP917 plaques used fewer radiation seeds by an average difference of 1.94 (P<.001; 95% confidence interval [CI], -2.8 to -1.06) and required less total strength of radiation sources by an average of 17.74 U (air kerma units) (P<.001; 95% CI, -20.16 to -15.32). The total radiation doses delivered to the optic disc, opposite retina, and macula were significantly less by 4.57 Gy, 0.50 Gy, and 11.18 Gy, respectively, with the EP917 plaques vs the COMS plaques. Conclusion: EP917 plaques deliver less overall radiation exposure to critical vision structures than COMS treatment plaques while still delivering the same total therapeutic dose to the tumor.

    Defects of the mitochondrial respiratory chain are associated with a great variety of clinical disorders. Whilst recognition of these conditions is increasing, the need for sophisticated biochemical and molecular studies has tended to limit both their investigation and diagnosis to a few specialist centres. Using a group of 51 patients with histochemically, biochemically and/or genetically defined respiratory chain defects, we have examined both the clinical heterogeneity of these disorders and how they may be investigated most effectively in non-specialist centres. We evaluated the use of the following routinely available clinical investigations--fasting intermediary metabolites (lactate, pyruvate, ketone bodies, etc.) in blood and cerebrospinal fluid, serum creatine kinase estimation, EMG, EEG, CT, MRI and histological/histochemical muscle biopsy analysis. Our studies show that, in addition to well-recognized syndromes (e.g. chronic progressive external ophthalmoplegia, mitochondrial encephalopathy lactic acidosis and stroke like episodes, and myoclonus epilepsy with ragged red-fibres, a significant number of patients present with non-specific encephalopathic disorders. Furthermore, even within those categories of respiratory chain disease which have been genetically defined, a wide variation of presenting symptoms and signs were found. Where there was initial doubt concerning the diagnosis, the following clinical features were helpful in suggesting respiratory chain disease: ophthalmoplegia; a maternal pattern of inheritance; the presence of myopathy or deafness in association with encephalopathy. Of the clinical investigations we assessed, elevated lactate in blood or cerebrospinal fluid and low density lesions in the basal ganglia were helpful in identifying patients with respiratory chain dysfunction. Histochemical analysis of muscle was, however, the single most useful investigation being diagnostic in patients with chronic progressive external

    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.

    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.

    During the past few decades, an increasing number of immunosuppressive drugs have been developed to treat autoimmune and rheumatic diseases, as well as post-transplant patients. In parallel, the incidence of immunocompromized patients in the general population has risen, for example, patients who are HIV positive, undergoing hemodialysis or suffering from diabetes mellitus. In such predisposed patients, infections with organisms of even reduced invasive potential can result in atypical invasive manifestations. In industrialized countries, an increase in the number of human non-typhoid Salmonella infections was observed in the 1980-1990s [Shimoni Z, Pitlik S, Leibovici L, Samra Z, Konigsberger H, Drucker M, et al. Nontyphoid Salmonella bacteremia: age-related differences in clinical presentation, bacteriology, and outcome. Clin Infect Dis 1999;28:822-7]. Beyond the main clinical manifestation of gastroenteritis, there is an increasing prevalence of extra-intestinal infections by this pathogen. We report a patient with acute osteomyelitis due to Salmonella typhimurium without any previous signs of gastroenteritis. PMID:18845462

    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

    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

    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. PMID:25238985

    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

    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.

    Objectives. Patients taking opioids prior to surgery experience prolonged postoperative opioid use, worse clinical outcomes, increased pain, and more postoperative complications. We aimed to compare preoperative opioid users to their opioid naïve counterparts to identify differences in baseline characteristics. Methods. 107 patients presenting for thoracotomy, total knee replacement, total hip replacement, radical mastectomy, and lumpectomy were investigated in a cross-sectional study to characterize the associations between measures of pain, substance use, abuse, addiction, sleep, and psychological measures (depressive symptoms, Posttraumatic Stress Disorder symptoms, somatic fear and anxiety, and fear of pain) with opioid use. Results. Every 9-point increase in the Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) score was associated with 2.37 (95% CI 1.29–4.32) increased odds of preoperative opioid use (p = 0.0005). The SOAPP-R score was also associated with 3.02 (95% CI 1.36–6.70) increased odds of illicit preoperative opioid use (p = 0.007). Also, every 4-point increase in baseline pain at the future surgical site was associated with 2.85 (95% CI 1.12–7.27) increased odds of legitimate preoperative opioid use (p = 0.03). Discussion. Patients presenting with preoperative opioid use have higher SOAPP-R scores potentially indicating an increased risk for opioid misuse after surgery. In addition, legitimate preoperative opioid use is associated with preexisting pain. PMID:26881072

    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

    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 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

    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

    Visceral leishmaniasis is a disease caused by a haemoflagellate protozoan of the genus Leishmania. It has a wide geographical spread. Classic cases are found primarily in children and present with typical features that include fever, anaemia, hepatosplenomegaly, hypergammaglobulinaemia, and pancytopenia. The diagnosis is usually achieved by bone marrow smears, culture and serology; however, it can manifest itself atypically, mostly in patients infected with HIV and geriatric immunocompetent patients. We report an unusual case of visceral leishmaniasis diagnosed in a 27 year-old HIV-infected male who presented with abdominal discomfort and diarrhoea of four weeks duration associated with nausea and vomiting, but with no typical symptoms or signs of visceral leishmaniasis. The diagnosis was established through the identification of the Leishmania organism in duodenal and colonic biopsies and confirmed by subsequent bone marrow smears. PMID:21969901

    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.

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

    Plasma cell balanitis (PCB), also knows as Zoon balanitis, is a benign asymptomatic but chronic and erosive inflammatory condition of the glans penis and prepuce that generally affects uncircumcised men in later years. Clinical presentation involves a single, shiny, well defined reddish patch. We describe the first case of PCB ever reported in a patient with a previous history of syphilis, and include a review of the current literature. A 57-year-old Hispanic man with a remote history of syphilis presented with a 6-month nonhealing, granulating ulcer of the foreskin and glans penis that had been repeatedly mistaken for syphilis and treated unsuccessfully with circumcision 3 weeks previously. Biopsy of the glans penis demonstrated sections with denuded chronic granulation tissue showing a fibrotic stroma with numerous blood vessels and a mixed inflammatory infiltrate including scattered plasma cells. It is important to differentiate PCB from a syphilitic chancre in a patient presenting with a nonhealing penile lesion. This case report demonstrates that these entities may be seen in the same patient at different times. PMID:21992223

    Histoplasmosis is usually an opportunistic fungal infection in patients with defective cell mediated immunity, and has been considered as one of the acquired immunodeficiency syndrome (AIDS) defining illness. However, cutaneous involvement in human immunodeficiency virus (HIV) positive patients is less common, and very rarely can be the initial presenting symptom for the diagnosis of AIDS. We present here an unusual case of multiple diffuse cutaneous nodular lesions predominantly in face, trunk, and upper extremities diagnosed initially on aspiration cytology as histoplasmosis. Subsequent serological test revealed positivity for HIV 1 and 2, along with a low CD4 count and low CD4:CD3 ratio. The cytomorphological features were further corroborated by histology and histochemical stains. Hence, cutaneous histoplasmosis can cause multiple wide spread nodular or umbilicated lesions in AIDS patients as the initial presentation. Fine needle aspiration cytology (FNAC) is a rapid, cost effective tool for diagnosis of the fungi from such lesions and initiating work up for immunocompromised states including AIDS. PMID:21987498

    Acute rhabdomyolysis is a rare phenomenon in the emergency setting almost exclusively associated with trauma, drugs, and recent upper respiratory and gastrointestinal infection. Rare reports in the literature have highlighted adult patients presenting with rhabdomyolysis as 1 component in a constellation of symptoms in acute HIV-1 seroconversion; however, there are few reports of rhabdomyolysis as the sole presenting symptom. This case highlights the importance of investigating HIV and other sexually transmitted diseases in pediatric cases of rhabdomyolysis in the emergency care setting. PMID:26584564

    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

  8. 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.

    Objective To determine the risk factors for Deliberate Self-Harm (DSH) in patients presenting to the Emergency Departments (EDs) of three tertiary care hospitals of Karachi, Pakistan. Study Design Multicentre matched case control study. Place and Duration of Study EDs of the Aga Khan University Hospital, Karachi, Civil Hospital, Karachi and Jinnah Postgraduate Medical Centre, Karachi, from March 2011 to February 2012. Methodology A total of 201 cases and 201 matched controls were taken from three hospitals situated in Karachi. All patients of 16 years and above presenting to the EDs of the hospitals with DSH attempt were invited to participate in the study. Controls were ED patients with complaints other than DSH. A control was matched with case for hospital, gender and age. Two questionnaires were used to collect information on the risk factors of DSH. Conditional Logistic Regression (CLR) was used to assess the association of various risk factors with DSH. Results Risk factors of DSH in Karachi included current history of mental disorder (OR = 4.53, 95% CI = 1.59 – 12.92), not sharing problems with someone (OR = 4.67, 95% CI = 2.4 – 9.0), living in rented houses (OR = 2.58, 95% CI = 1.37 – 4.84), Pathan ethnicity (OR = 5.05, 95% CI = 1.01–25.38) followed by others (OR = 3.88, 95% CI = 0.77 – 19.69) and Urdu speaking (OR = 2.71, 95% CI = 0.59 – 12.45). Absence of physical illness in the past month had an inverse association with DSH (OR = 0.17, 95% CI = 0.07 – 0.37). Conclusion Mental illnesses, low socio-economic status and loneliness were the risk factors of DSH patients presenting to the three EDs of Karachi. Physical illness in the last month was protective against DSH in these patients. Psychiatric evaluation of DSH patients in the ED is important for early diagnosis and management of mental disorders.

    As the number of percutaneous coronary interventions increase annually, patients with intracoronary stents (ICS) who present for noncardiac surgery (NCS) are also on the rise. ICS is associated with stent thrombosis (STH) and requires mandatory antiplatelet therapy to prevent major adverse cardiac events. The risks of bleeding and ischemia remain significant and the management of these patients, especially in the initial year of ICS is challenging. The American College of Cardiologists guidelines on the management of patients with ICS recommend dual antiplatelet therapy (DAT) for minimal 14 days after balloon angioplasty, 30 days for bare metal stents, and 365 days for drug-eluting stents. Postponement of elective surgery is advocated during this period, but guidelines concerning emergency NCS are ambiguous. The risk of STH and surgical bleeding needs to be assessed carefully and many factors which are implicated in STH, apart from the type of stent and the duration of DAT, need to be considered when decision to discontinue DAT is made. DAT management should be a multidisciplinary exercise and bridging therapy with shorter acting intravenous antiplatelet drugs should be contemplated whenever possible. Well conducted clinical trials are needed to establish guidelines as regards to the appropriate tests for platelet function monitoring in patients undergoing NCS while on DAT. PMID:26750683

    Idiopathic short stature is a multifactorial disease caused by defects in several genes. Among them, short stature homeobox-containing gene (SHOX) mutations have an incidence of 2%-15% within the idiopathic short population. The authors report a patient with moderate intellectual disability, short stature and no other radiological traits referred for subtelomeric screening. MLPA and sequencing results showed a heterozygous mutation in SHOX gene (A170P). This mutation has been described to fully cosegregate with Madelung deformity in patients affected with Léri-Weill dyschondrosteosis and Langer mesomelic dysplasia. The authors report the first case of idiopathic short stature due to the A170P mutation in a patient without any radiological trait. The A170P mutation is the most prevalent mutation in the Spanish gypsy population affected with short stature disorders. The authors strongly recommend SHOX screening for deletions, duplications and point mutations in patients affected with short stature although they do not present any radiological traits.

    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.

    BACKGROUND/AIMS—Out of an estimated 90 000 visually impaired people in Scotland, 509 make use of a guide dog. Initial research in Northern Ireland suggests that the ophthalmic profile of guide dog owners (GDOs) is highly specific. The aim of this study was to compare the ophthalmic and visual characteristics of Scottish GDOs with other groups of visually impaired people.
METHODS—A random sample of GDOs from central and northern Scotland (n=82) underwent a detailed assessment of residual vision (distance and near acuity, visual fields, contrast, and glare sensitivity). Comparative data were obtained from two populations of visually impaired non-GDOs—one group attending hospital ophthalmic and low vision clinics (n=50) the other social services rehabilitation clients (n=35). All participants completed a questionnaire to elicit ophthalmic history, age, and registration details.
RESULTS—GDOs were found to be significantly younger and more profoundly visually impaired than non-GDOs. The main causes of visual impairment were retinitis pigmentosa (23%), optic atrophy (15%), and retinopathy of prematurity (7%). Ninety nine per cent of GDOs were registered blind and had been visually impaired for an average of 39 years. Only 31% were totally blind.
CONCLUSION—GDOs represent a unique minority of the visually impaired population. Epidemiological registration trends would suggest that the numbers of young profoundly visually impaired people are unlikely to increase relative to their elderly counterparts. This has implications on the future demand for guide dog ownership.

    2016-01-01

    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.

    2015-01-01

    Background/Aim: The recent years have witnessed an increase in number of people harboring chronic liver diseases. Gastroesophageal variceal bleeding occurs in 30% of patients with cirrhosis, and accounts for 80%-90% of bleeding episodes. We aimed to assess the in-hospital mortality rate among subjects presenting with variceal gastrointestinal bleeding and (2) to investigate the predictors of mortality rate among subjects presenting with variceal gastrointestinal bleeding. Patients and Methods: This retrospective study was conducted from treatment records of 317 subjects who presented with variceal upper gastrointestinal bleeding to Government Medical College, Patiala, between June 1, 2010, and May 30, 2014. The data thus obtained was compiled using a preset proforma, and the details analyzed using SPSSv20. Results: Cirrhosis accounted for 308 (97.16%) subjects with bleeding varices, with extrahepatic portal vein obstruction 9 (2.84%) completing the tally. Sixty-three (19.87%) subjects succumbed to death during hospital stay. Linear logistic regression revealed independent predictors for in-hospital mortality, including higher age (P = 0.000), Child-Pugh Class (P = 0.002), altered sensorium (P = 0.037), rebleeding within 24 h of admission (P = 0.000), low hemoglobin level (P = 0.023), and serum bilirubin (P = 0.002). Conclusion: Higher age, low hemoglobin, higher Child-Pugh Class, rebleeding within 24 h of admission, higher serum bilirubin, and lower systolic blood pressure are the independent predictors of in-hospital mortality among subjects presenting with variceal gastrointestinal bleeding.

    Autoimmune autonomic ganglionopathy (AAG) is an acquired immune-mediated disorder that leads to systemic autonomic failure. Autoantibodies to the ganglionic nicotinic acetylcholine receptor (gAChR) are detected in 50% of AAG patients. We report the first pediatric case of AAG presenting with acute encephalitis. The patient was a 13-year-old boy who presented with orthostatic hypotension, followed by rapidly progressing disturbance of consciousness. Cerebrospinal fluid analysis revealed significant pleocytosis and increased neopterin concentration. Head MRI showed hyperintensities in bilateral caudate nuclei, putamen, hippocampus, and insula cortex. Severe autonomic dysfunctions such as severe orthostatic hypotension, bradycardia, dysuria, prolonged constipation and vomiting appeared. These symptoms were successfully controlled by repeated immunomodulating therapy with intravenous methylprednisolone pulse therapy and intravenous immunoglobulin. Autoantibodies to the α3 subunit of gAChR were detected at neurological onset, but were undetectable five months later. This observation indicates that AAG should be suspected in patients manifesting acute encephalitis characterized by preceding and prolonged autonomic symptoms, and immunomodulating therapy from an early stage can be effective.

    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.

    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
