    Measuring corneal biomechanical properties may help detect keratoconus suspect corneas and eliminate the risk of ectasia after LASIK. Data of 504 eyes separated into three groups were retrospectively reviewed: normal (n = 252), keratoconus suspect (n = 80), and keratoconus (n = 172). Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured with an ocular biomechanics analyzer. Mean corneal hysteresis was 10.6 +/- 1.4 (SD) mm Hg in the normal group, compared with 10.0 +/- 1.6 mm Hg in the keratoconus suspect group and 8.1 +/- 1.4 mm Hg in the keratoconus group. The mean CRF was 10.6 +/- 1.6 mm Hg in the normal group compared with 9.7 +/- 1.7 in the keratoconus suspect group and 7.1 +/- 1.6 mm Hg in the keratoconus group. Mean CH and CRF were significantly different between the three groups (P corneas. Analyzing signal curves obtained with the biomechanics analyzer may provide additional valuable information for selecting qualified patients for refractive surgery.

    Full Text Available Chlamydia trachomatis, an obligate intraocular bacteria causing trachoma, adult and neonatal inclusion conjunctivitis, was the leading cause of blindness in the last century worldwide. Improvement in socioeconomic and living conditions, availability of antibiotics, and introduction of National Trachoma Control Programmes reduced the prevalence in developed countries, but it persisted in resource-poor settings of Africa and Asia, including India. In 2016, as per the WHO report, trachoma is restricted to 42 countries, causing blindness/visual impairment in ~1.9 million people. India is one of the five countries with nearly half of total active trachoma patients. Introduction of Global Elimination of Trachoma 2020 program by the WHO, using SAFE strategy (surgery for trachomatous trichiasis; Antibiotics for C. trachomatis; Facial cleanliness; and environmental improvement greatly reduced the prevalence, but trachoma still persists in India. Global increase in the reproductive tract infection by C. trachomatis urogenital serotypes (D-K has led to concurrent increase in C. trachomatis eye infections. Therefore, kerato eye infections due to chlamydial infections continue to be seen in hospitals. Over the years, there have been advances in laboratory diagnostics, in understanding the pathogenesis, tissue tropism, C. trachomatis genomics, and treatment modalities. Due attention and research is still needed for the study of C. trachomatis eye infections.

    A 32-year-old woman, 5-year-old girl, and 33-year-old man visited our otorhinolaryngology outpatient clinic with tumentia of the unilateral parotid gland. A high titer of serum IgG antibodies against the mumps virus was detected. Around the same time, other members of their families had the same parotid tumentia, and they were diagnosed as having their first mumps infection. Therefore, the diagnosis of the three cases was strongly suspected to be re-infection with mumps. In Japan, it was classically believed that the mumps virus infection occurs only once in patients and reinfection doesn't occur. However, some pediatricians in Japan have reported that re-infection with mumps is strongly suspected when high titers of serum IgG antibodies against the mumps virus are found at the initial visit. It is now believed many more examples of mumps re-infection cases have existed than we previously believed. When high titers of serum IgG antibodies against the mumps virus are detected at an initial visit in patients who have had mumps previously, re-infection should be strongly suspected. And to make it certain, we suggest that the mumps IgG antibodies should be checked twice to confirm the diagnosis. If elevation of the IgG antibodies persist, the diagnosis will be much more certain.

    To determine the cumulative prevalence of septic arthritis presenting to the emergency department of an academic medical center and evaluate the use of clinical data to diagnose infection versus inflammation. We conducted a records review of a single institution with 80,000 annual emergency room visits. We included a consecutive series of patients with suspected wrist infection from January 1, 2007, to December 31, 2008. Adults complaining of atraumatic wrist pain with either erythema or swelling on physical examination or a final diagnosis of septic arthritis, gout, pseudogout, cellulitis, wrist hematoma/edema, or wrist arthritic flare were suspected to have infection. We collected data using a standardized data abstraction form. We reviewed 804 patient records. A total of 104 patients meeting inclusion criteria for suspected wrist joint infection during the 2-year study period were included. Mean age was 62.5 years (SD, 20.2 y); 63 were men. There were 12 patients with a history of gout, 4 with a history of pseudogout, and 19 with a history of diabetes. Wrist arthrocentesis was performed in 31 patients, and 11 underwent surgical treatment. There were 16 patients with a final diagnosis of gout, 11 with pseudogout, 43 with cellulitis, 13 with upper extremity hematoma/edema, and 15 with wrist arthritic flare. The cumulative prevalence of septic arthritis was 5%. In this series of emergency department patients with suspected wrist joint infection, gout, pseudogout, and cellulitis were the most common etiologies. The cumulative incidence of septic wrist arthritis was low. Copyright © 2011 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.

    The goal of this study is to identify clinical variables associated with bacteremia. Such data could provide a rational basis for blood culture testing in emergency department (ED) patients with suspected infection. This is a secondary analysis of a prospective cohort of ED patients with suspected infection. Data collected included demographics, vital signs, medical history, suspected source of infection, laboratory and blood culture results and outcomes. Bacteremia was defined as a positive blood culture by Centers for Disease Control criteria. Clinical variables associated with bacteremia on univariate logistic regression were entered into a multivariable model. There were 5630 patients enrolled with an average age of 59.9 ± 19.9 years, and 54% were female. Blood cultures were obtained on 3310 (58.8%). There were 409 (12.4%) positive blood cultures, of which 68 (16.6%) were methicillin-resistant Staphylococcus aureus (MRSA) and 161 (39.4%) were Gram negatives. Ten covariates (respiratory failure, vasopressor use, neutrophilia, bandemia, thrombocytopenia, indwelling venous catheter, abnormal temperature, suspected line or urinary infection, or endocarditis) were associated with all-cause bacteremia in the final model (c-statistic area under the curve [AUC], 0.71). Additional factors associated with MRSA bacteremia included end-stage renal disease (odds ratio [OR], 3.9; 95% confidence interval [CI], 1.9-7.8) and diabetes (OR, 2.0; 95% CI, 1.1-3.6) (AUC, 0.73). Factors strongly associated with Gram-negative bacteremia included vasopressor use in the ED (OR, 2.8; 95% CI, 1.7-4.6), bandemia (OR, 3.5; 95% CI, 2.3-5.3), and suspected urinary infection (OR, 4.0; 95% CI, 2.8-5.8) (AUC, 0.75). This study identified several clinical factors associated with bacteremia as well as MRSA and Gram-negative subtypes, but the magnitude of their associations is limited. Combining these covariates into a multivariable model moderately increases their predictive value. Copyright

    Vancomycin and teicoplanin are commonly used to treat gram-positive infections, particularly those caused by methicillin-resistant Staphylococcus aureus (MRSA). There is uncertainty regarding the effects of teicoplanin compared to vancomycin on kidney function with some previous studies suggesting teicoplanin is less nephrotoxic than vancomycin. To investigate the efficacy and safety of vancomycin versus teicoplanin in patients with proven or suspected infection. We searched the Cochrane Renal Group's Specialised Register, CENTRAL, MEDLINE, EMBASE, reference lists of nephrology textbooks, review articles with relevant studies and sent letters seeking information about unpublished or incomplete studies to investigators involved in previous studies. We searched for randomised controlled trials (RCTs) in any language comparing teicoplanin to vancomycin for patients with proven or suspected infection. Two authors independently evaluated methodological quality and extracted data using standardised data extraction forms. Study investigators were contacted for information not available in the original manuscripts. Random effects model was used to estimate the pooled risk ratio (RR) with 95% confidence interval (CI). We included 24 studies (2,610 patients) in this review. Teicoplanin reduced the risk of nephrotoxicity compared to vancomycin (RR 0.66, 95% CI 0.48 to 0.90).The effects of teicoplanin or vancomycin were similar for clinical cure (RR 1.03, 95% CI 0.98 to 1.08), microbiological cure (RR 0.98, 95% CI 0.93 to 1.03) and mortality (RR 1.02, 95% CI 0.79 to1.30). Six studies reported no cases of acute kidney injury (AKI) needing dialysis. Adverse events were less frequent with teicoplanin including cutaneous rash (RR 0.57, 95% CI 0.35 to 0.92), red man syndrome (RR 0.21, 95% CI 0.08 to 0.59) and total adverse events (RR 0.73, 95% CI 0.53 to 1.00). A lower risk of nephrotoxicity with teicoplanin was observed in patients either with (RR 0.51, 95% CI 0.30 to 0.88) or

    To describe the intereye asymmetry in patients with keratoconus (KC), keratoconus suspect (KCS) and normal participants, and to evaluate the relationship between asymmetry and disease severity. In this prospective observational comparative study, 446 patients with bilateral KC, 68 patients with bilateral KCS and 306 normal participants underwent topographic, keratometric and pachymetric evaluations by Pentacam as well as refractive and visual acuity examinations. The intereye asymmetry in each parameter was calculated and compared between the groups. All parameters were significantly different between the worse and better eyes in the KC group (p0.05). There was a statistically significant greater intereye asymmetry in all parameters in the KC group compared with the KCS and normal groups (pKeratoconus Severity Score classification (p<0.05). According to receiver operating characteristic analysis, the intereye asymmetry would effectively discriminate KC and KCS from normal eyes. KC is an asymmetric disease, and the degree of asymmetry is associated with disease severity. The analysis of intereye asymmetry should be performed along with unilateral evaluation in the screening of KC. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To describe the clinical characteristics, management and long-term outcome in dogs with suspected rapid eye movement sleep behaviour disorder. Medical records and video recordings of 14 dogs with suspected rapid eye movement sleep behaviour disorder were reviewed and the owners were contacted via telephone or email for further information. Clinical signs included episodes of violent limb movements, howling, barking, growling, chewing, or biting during sleep. Episodes occurred at night and during daytime naps. The age at onset ranged from 8 weeks to 7·5 years with a median of 6 years but 64% of dogs were one year or less. There was no apparent sex or breed predisposition. Rapid eye movement sleep behaviour disorder events were reduced in severity and frequency in 78% of the dogs treated with 40 mg/kg/day oral potassium bromide. One dog was euthanized within 3 months of the onset of signs because of their severity. The duration of the disorder in the 13 surviving dogs ranged from 1·5 to 9 years. None of the dogs spontaneously recovered. Rapid eye movement sleep behaviour disorder is suspected to occur in dogs, as it does in human beings. It causes concern to the owners and disrupts the home environment. Unlike human beings, rapid eye movement sleep behaviour disorder of dogs often has a juvenile onset. © 2011 British Small Animal Veterinary Association.

    Full Text Available A special attention in the embryo damaging should be paid to mother'sinfections in the first three months of the intra-uterine development. Mother'sinfections can strike many organs of the embryo while a specially sensitive problemis the one with the sense of seeing. Most frequently these infections are caused byToxoplasma gondii, Citomegalovirus, Herpes simplex virus, Rubella and VaricellaZoster virus.The eye manifestations of the congenital toxoplasmosis are retinochoroidities,80% of them localized in the macula region (in 50% ofthe cases in both the eyes, andmicrophtalamos in 40% to 70% of the cases as well as iridocyclities and cataracta.The cytomegalovirus, in a congenital infection, causes chorioretinitis withmultiple yellowish-whitish segments, vasculitis and hemorrhages, microphtalmiaand strabismus.The most frequent changes induced by the rubella infections are microphtalamos,congenital cataracta, retinopathy and uveities.The herpes simplex virus as the cause of a congenital infection leads tochorioretinitis and keratoconjuctivities while the varicella-zoster virus infectiongives rise to chorioretinitis and cataracta.

    To perform prediction analysis between topographic, pachymetric and wavefront parameters in keratoconus, suspects, and normal cases and to look at the possibility of a unified equation to evaluate keratoconus. This cross-sectional, observational study was done in cornea services of a specialty hospital. Fifty eyes of 50 candidates with a diagnosis of normal, keratoconus suspect, and keratoconus were included in each group (total 150 eyes). All eyes underwent detailed analysis on Scheimplug + Placido device (Sirius, CSO, Italy). Main parameters evaluated were topographic [maximum keratometry (Max Km), average keratometry and astigmatism at 3, 5, and 7 mm], pachymetric [central and minimum corneal thickness (MCT) and their difference, corneal volume] and corneal aberrations [higher order aberrations root-mean-square (HOARMS), coma, spherical, residual].Central tendency, predictive fits and regression models, were computed. The measured variables had a significant difference in mean between the three groups (Kruskal-Wallis, p keratoconus (R(2) from 0.75 to 0.33) compared to suspect/normal eyes (R(2) from 0.15 to 0.003). These three variables (Max Km, MCT and HOARMS) were used as representative variables to create the unified equations. The equation for the pooled data was (Kmax = 59.5 + 2.3 × HOARMS-0.03 × MCT; R(2)= 0.7, p keratoconus (MaxKm, MCT, HOARMS) can be linked by linear regression equations to predict the pathology's behavior.

    Conclusion: the results suggest that viral infection can be present in hospitalized infants with clinical suspicion of pertussis, and etiological tests may enable a reduction in the use of macrolides in some cases. However, the etiological diagnosis of respiratory virus infection, by itself, does not exclude the possibility of infection with BP.

    The authors report on an infant suspected of having been abused, who presented with periorbital edema and ecchymoses (clinial `raccoon eyes`). The pattern of the nuclear medicine bone scan suggested neuroblastoma rather than trauma. Both the bone scan and the subsequent MIBG scan revealed multiple abnormalities, including markedly increased activity around the orbits, that we termed the `scintigraphic raccoon eyes` sign. In addition, the grossly abnormal MIBG scan demonstrated avid uptake of MIBG throughout the entire skeleton with essentially complete absence of visualization of the liver and heart (the `MIBG super scan`). These signs have not previously been described in an infant or a child with neuroblastoma. (orig.)

    To analyse tomographic changes in eyes classified as 'normal', 'keratoconus-suspect' and 'clinically manifest keratoconus' based on the established KISA% definition of Rabinowitz and Rasheed and to develop the category of 'subclinical keratoconus eyes' to expand the classification into a 'subtopographic' range. Tomographic and topographic analyses of 670 eyes performed with a rotating Scheimpflug imaging system (Pentacam(®), Oculus Inc., Wetzlar, Germany) were retrospectively analysed. Based on the KISA% keratoconus classification system, eyes were assigned to a 'normal', 'keratoconus-suspect' or 'manifest keratoconus' group. In addition, a new group of 'subclinical keratoconus eyes' was analysed, comprising unsuspicious fellow eyes of patients with keratoconus. T-tests, Wilcoxon rank-sum test, receiver operating characteristics (ROC) and robust regression analyses were performed to correlate tomographic parameters with the increasing KISA% index. KISA%-grouped keratoconus eyes showed robust tomographic changes. By adding the subclinical group, although the concurrent topography was unchanged, we were able to demonstrate statistically significant changes for almost all tomographic parameters (parameters with highest sensitivity/specificity: ART_max, [0.69/0.69], BAD_D [0.66/0.66]). The highest coefficient of determination (R(2)) with the KISA% index was demonstrated for Ele_f_max (R(2) = 0.70), Ele_f_TP (R(2) = 0.69), Ele_b_TP (R(2) = 0.69) and BAD_D (R(2) = 0.68). We recommend the use of the expanded KISA% index (eKISA% index) as the basis for the definition of keratoconus and normal groups in future keratoconus research projects. © 2015 Acta Ophthalmologica Scandinavica Foundation.

    Full Text Available Purpose: To study the outcome of ocular nocardiosis following intraocular surgery. Materials and Methods: A retrospective review of medical records of all postoperative cases of culture proven Nocardia infection over a period of 3 years, from October 2010 to September 2013, was performed. Microbiological analysis was performed for all cases and included smears and cultures. Fortified 2% amikacin eye drops were the mainstay of treatment. Surgical intervention was performed in case of nonresponse to medical therapy or suspected endophthalmitis. Results: Seven cases of culture proven Nocardia infection were seen. All cases had been operated in a hospital surgical facility. Six followed phacoemulsification, and one followed a secondary intraocular lens implantation. Four patients were part of a cluster infection. The mean duration between the primary surgical procedure and presentation was 16.14 ± 9.82 days. Five patients had infiltrates at the site of the surgical incision. One each had endophthalmitis and panophthalmitis. Six eyes required surgical intervention. Infection was seen to resolve in four eyes. Two eyes went into phthisis, and one was eviscerated. Only two of the six eyes, where in surgical intervention was performed early, obtained a final visual acuity of 20/60. Conclusion: Early surgical intervention, before the involvement of the anterior chamber, may help preserve the anatomic and functional integrity of the eye.

    Intraocular pressure (IOP) measurements are affected by the central cornea thickness (CCT). The conventional method for CCT measurement is ultrasonic pachymetry. However, noncontact procedures lower the risk of infection and corneal damage. In this study, we compared the CCT measured by Orbscan II, SP3000P, and ultrasonic pachymetry in patients with glaucoma or glaucoma suspect. The CCT of 208 eyes (46 eyes with glaucoma suspect, 42 with primary angle-closure glaucoma, and 120 with primary open-angle glaucoma) was measured using Orbscan II, SP3000P, and ultrasonic pachymetry. We compared the linear correlation of the CCT between each mode. The mean CCT measured by Orbscan II (563.63 ± 35.867 µm) was larger than with the other two devices. There were significant linear correlations between measurements with ultrasonic pachymetry and Orbscan II (Pearson correlation coefficient (r) = 0.793, p measured with ultrasonic pachymetry: ≤ 500 µm, > 500 µm to ≤ 578 µm, and > 578 µm. There was no significant linear correlation between ultrasonic pachymetry and Orbscan II in the thin group. But, in the intermediate and thick CCT groups, there were significant linear correlations between each of the three devices. We showed good linear correlations of CCT measurements between each of 3 devices, especially in the intermediate and thickest CCTs. These results will be helpful in predicting the relationship between IOP and CCT for the diagnosis and screening of glaucoma; even we used optic systems.

    To determine the diagnostic yield of skin biopsy in patients with leukemia, new skin lesions, and suspected infection. We reviewed the medical records of all patients with leukemia who underwent skin biopsy for new lesions and clinical suspicion of infection over 4 years. Biopsy was considered to have changed the diagnosis, if the results differed from the prior leading clinical impression. Seventy-six (39%) of 195 patients had infections identified via skin biopsy. Among the remaining patients, the most common diagnoses were leukemia cutis, drug reactions and Sweet's syndrome. Ulcerated or necrotic lesions and bacteremia or fungemia were the only independent predictors of infection. 55% of patients with severe neutropenia had biopsy-proven infectious causes of their skin lesions. One third of all afebrile patients had skin manifestations owing to infection. Skin biopsy results differed from the initial clinical impression in 34% of all patients. In 45% of infected patients, pathogens were identified by skin biopsy alone. Noninfectious causes accounted for a large proportion of new skin lesions in leukemia patients with suspected infections. Absence of neutropenia or fever did not rule out infection. Ulcerated or necrotic lesions and bacteremia or fungemia were independent predictors of infection. In the evaluation of patients with leukemia and new skin lesions, skin biopsy remains an important procedure to rule out infection, and is particularly useful for pathogen identification.

    Ophthalmologists are still facing difficulties in managing bacterial eye infections. The study was designed for the isolation and identification of bacteria from infected eyes and observation of the sensitivity and resistant pattern. This cross sectional study was performed among 160 patients of suspected bacterial eye infection at Dr. K. Zaman BNSB Eye Hospital, Mymensingh and Department of Microbiology and Hygiene, Bangladesh Agricultural University, Mymensingh from March, 2010 to June, 2014. After collection of the samples from suspected infected eyes, it was nourished into nutrient broth in shaking incubator for three hours and then cultured into nutrient agar media followed by Mannitol salt agar, MacConkey's agar and blood agar. Bacteria were categorized by colony characteristics and Gram staining. Antibiogram was performed by disc diffusion method on Mueller Hinton agar media. McFarland Equivalence Turbidity Standard was maintained. The efficacy of the drug was evaluated by measuring the diameter of the zone of inhibition surrounding the disc. Ten percent Staphylococcus species isolates was resistant to Gatifloxacin, Gentamicin, Tobramycin and Cloxacillin, 26.0% to Ciprofloxacin, 40.0% to Azythromycin and Moxifloxacin, 58.0% to Cefixime and 64.0% to Cephalexin. Methicillin resistant Staphylococcus aureus was 62.8%. About 24.0% Streptococcus species isolates was resistant to Gatifloxacin, 33.3% to Azythromycin, Ciprofloxacin, Gentamycin, Moxifloxacin and Tobramycin, 52.4% to Cefixime and 71.4% to Cephalexin. About 9.0% of Pseudomonas species was resistant to Gatifloxacin and Tobramycin, 14.7% to Ciprofloxacin, 26.5% to Cefixime, 29.4% to Gentamicin and Moxifloxacin, 44.1% to Azythromycin and 82.3% to Cephalexin and Cloxacillin. Rational use of antibiotics and proper attentions of concerned authorities are necessary to overcome the emergent ocular situation leaded by antibiotic resistant.

    Aspergillus and Candida species are the main causative agents of invasive fungal infections in immunocompromised human hosts. However, saprophytic fungi are now increasingly being recognized as serious pathogens. Trichoderma longibrachiatum has recently been described as an emerging pathogen in immunocompromised patients. We herein report a case of isolated suspected invasive pulmonary infection with T. longibrachiatum in a 29-year-old man with severe aplastic anemia who underwent allogeneic stem cell transplantation. A direct microscopic examination of sputum, bronchoaspiration, and bronchoalveolar lavage fluid samples revealed the presence of fungal septate hyphae. The infection was successfully treated with 1 mg/kg/day liposomal amphotericin B.

    Conclusion: CH and CRF can be helpful in differentiating KC from NL eyes; however, they are not valuable for detecting KCS that is the main concern for refractive surgery. Future studies focusing on more accurate tests for identifying KCS, using a consistent grading scale for defining KC and KCS are still warranted.

    The emerging disease Buruli ulcer is treated with streptomycin and rifampicin and surgery if necessary. Frequently other antibiotics are used during treatment. Information on prescribing behavior of antibiotics for suspected secondary infections and for prophylactic use was collected retrospectively. Of 185 patients that started treatment for Buruli ulcer in different centers in Ghana and Bénin 51 were admitted. Forty of these 51 admitted patients (78%) received at least one course of antibiotics other than streptomycin and rifampicin during their hospital stay. The median number (IQR) of antibiotic courses for admitted patients was 2 (1, 5). Only twelve patients received antibiotics for a suspected secondary infection, all other courses were prescribed as prophylaxis of secondary infections extended till 10 days on average after excision, debridement or skin grafting. Antibiotic regimens varied considerably per indication. In another group of BU patients in two centers in Bénin, superficial wound cultures were performed. These cultures from superficial swabs represented bacteria to be expected from a chronic wound, but 13 of the 34 (38%) S. aureus were MRSA. A guide for rational antibiotic treatment for suspected secondary infections or prophylaxis is needed. Adherence to the guideline proposed in this article may reduce and tailor antibiotic use other than streptomycin and rifampicin in Buruli ulcer patients. It may save costs, reduce toxicity and limit development of further antimicrobial resistance. This topic should be included in general protocols on the management of Buruli ulcer.

    Full Text Available Purpose: The aim of the present study was to evaluate the effect of surgical peripheral iridectomy (SPI on choroidal thickness in primary angle-closure suspect (PACS eyes. Materials and Methods: This was a prospective observational case series of 30 subjects with PACS. Ocular biometry was performed before SPI (baseline and then 1 week later. Choroid was imaged by enhanced depth imaging optical coherence tomography (EDI-OCT. The choroidal thickness of the subfoveal area at 1 and 3 mm diameter around the fovea was determined. Central anterior chamber depth (ACD, lens thickness (LT, vitreous chamber depth (VCD, and axial length (AL were measured by A-scan ultrasound. Parameters were compared before SPI (baseline and 1 week later. Results: Thirty eyes of 30 patients with mean age of 61.53 ± 7.98 years were studied. There was no significant difference in the choroidal thickness at all macular locations before and after SPI (all P > 0.05. Mean subfoveal choroidal thickness was 279.61 μm ± 65.50 μm before and 274.54 μm ± 63.36 μm after SPI (P = 0.308. There was also no significant change in central ACD, LT, VCD, and LT after SPI (all P > 0.05. Conclusions: SPI does not appear to alter choroidal thickness in PACS eyes, as assessed using EDI-OCT. Long-term follow-up of PACS eyes treated with SPI may provide further insight into the effects of this treatment modality on the choroid.

    Full Text Available Background: Frequent infections is among the most frequent clinical dilemmas for primary care physicians. Immunodeficiency disorders are a heterogeneous group of illnesses that predispose patients to the recurrent infections, autoimmunity and malignancies. The aim of this study was to evaluate the clinical and laboratory data collected for the final diagnosis of patients referred with recurrent infections and suspected immunodeficiency to a local immunodeficiency clinic.   Methods: This epidemiological study was carried out between April 2010 and September 2012 at the Immunodeficiency Clinic of Mashhad. All patients with clinical manifestations of immunodeficiency who were referred to our clinic during this period of time were included in this study. 41 patients aged from 10 months to 51 years, were evaluated. Results: Forty one patients, aged between 10 months and 51 years were evaluated. Eleven patients had a primary immunodeficiency, four cases had a secondary immunodeficiency, in three patients an underlying structural disease were found, eight patients were predisposed to recurrent infections as a result of allergies and finally, fifteen cases were found to be normal individuals.   Discussion: Most patients with recurrent infection have a normal immune system. Allergic disorders are the most common predisposing factor to recurrent infection. However, as immunodeficiency disorders are potentially serious, early diagnosis can improve the quality of life and outcome and prevent severe sequels in future.

    To retrospectively determine the effectiveness and accuracy of CT-guided percutaneous biopsy of malignant and inflammatory bone lesions of the spine and to assess the reliability of pre-biopsy CT and MRI. 214 patients with lesions of the spine, which were suspicious either for being malignant or inflammatory, underwent CT-guided biopsy for pathological and/or microbiological detection. Biopsy samples were sent for histological examination in 128/214 patients, for microbiological analysis in 17/214 patients and for both analyses in 69/214 patients. Retrospectively, the diagnostic accuracy and sensitivity/specificity of the pre-interventional imaging (CT and MRI) were determined. In addition, the influence of the biopsy on subsequent patient management was assessed. The accuracy was 94.4% for histopathological analysis and 97.7% for microbiological analysis. In 25% of cases the microbiological analysis revealed an underlying pathogen that was not significantly affected by pre-biopsy antibiotic therapy. The sensitivity/specificity of the pre-biopsy cross-sectional imaging concerning suspected malignancy was 69%/78%. For suspected infection, the sensitivity/specificity of pre-biopsy imaging was 81%/44%. In 52% of all cases, the biopsy result changed subsequent patient management. Percutaneous CT-guided spine biopsy is a useful and reliable diagnostic procedure to establish a definitive diagnosis but with a relatively low yield of microorganisms in the case of infection.

    Pilot study of the role of RetCam imaging for telemedicine in lieu of availability of ophthalmologist examination for cases of suspected abusive head injury. Cross-sectional observational study. 21 children admitted in the paediatric units of the University Hospital of Strasbourg (France) with suspicion of abusive head trauma were included. Children were examined by standard ophthalmoscopy. Photographs were taken using the RetCam-120 Digital Retinal Camera. Eye fundus images were stored and remotely read by an ophthalmologist. Patients also had radiographic skeletal series to look for bone fractures, and CT scan and/or MRI of the head to look for intracranial haemorrhages. The absence or presence of retinal haemorrhages was assessed by both methods. Feasability, sensitivity and specificity of the digital camera procedure were determined. 85.7% of the children presented cerebral bleeding, and 14 out of the 21 (66.7%) had retinal haemorrhages on ophthalmoscopy. The digital camera detected the retinal abnormalities in all cases. One false-positive case was also reported. The sensitivity of the digital camera detection method was 100% with a specificity of 85.7%. 14 patients were eventually diagnosed as suffering from abusive trauma. RetCam helped establishing the diagnosis of abuse in 92.8% of these cases. Digital photography compared with ophthalmoscopy has a good sensitivity and specificity in detecting retinal haemorrhages. Remote reading of RetCam-120 photographs could be a promising strategy in detecting children with abusive head trauma.

    HIV infection is a risk factor for opportunistic pneumonias such as tuberculosis (TB) and for age-associated health complications. Short telomeres, markers of biological aging, are also associated with an increased risk of age-associated diseases and mortality. Our goals were to use a single cohort of HIV-infected and HIV-uninfected individuals hospitalized with pneumonia to assess whether shortened telomere length was associated with HIV infection, TB diagnosis, and 2-month mortality. This was a sub-study of the IHOP Study, a prospective observational study. Participants consisted of 184 adults admitted to Mulago Hospital in Kampala, Uganda who underwent evaluation for suspected TB and were followed for 2 months. Standardized questionnaires were administered to collect demographic and clinical data. PBMCs were isolated and analyzed using quantitative PCR to determine telomere length. The association between HIV infection, demographic and clinical characteristics, and telomere length was assessed, as were the associations between telomere length, TB diagnosis and 2-month mortality. Variables with a P≤0.2 in bivariate analysis were included in multivariate models. No significant demographic or clinical differences were observed between the HIV-infected and HIV-uninfected subjects. Older age (Paging and that shorter telomeres may be involved in age-associated health complications seen in this population. The findings indicate a need to further research the impact of HIV on aging.

    Full Text Available Perimetry is indispensable for the clinical management of glaucoma suspects. Our goal is to compare the performance of standard automated perimetry (SAP and Matrix frequency-doubling technology (FDT perimetry in monitoring the development of visual field (VF defects in glaucoma suspect eyes.Longitudinal data of paired SAP and FDT from 221 eyes of 155 glaucoma suspects enrolled in the Diagnostic Innovations in Glaucoma Study or the African Descent and Glaucoma Evaluation Study were included. All eyes had glaucomatous optic neuropathy or ocular hypertension, but normal SAP and FDT results at baseline. The development of glaucomatous VF defects was defined as the presence of a cluster of ≥ 3 (less conservative or ≥ 4 (more conservative locations confirmed on ≥ 2 additional consecutive tests. Risk factors for the development of VF defects were analyzed by COX proportional hazard models. After conversion into common logarithmic units, the rates of change of global VF indices were fitted with linear mixed models.FDT detected more eyes that developed VF defects than SAP using the less conservative criterion, and no significant difference was observed using the more conservative criterion. For those eyes detected by both SAP and FDT, FDT detected the development of VF defects either earlier than SAP or simultaneously in most cases. Baseline structural measurements were not significantly associated with an increased risk for the development of glaucomatous VF defects on either SAP or FDT. Older age was significantly associated with the development of VF defects on FDT but not on SAP. Both SAP and FDT detected a progressing worsening trend of pattern standard deviation over time with a similar rate of change between these test types.Matrix FDT would be useful to monitor the onset of VF defects in glaucoma suspects and may outperform SAP in the early stage of glaucomatous VF damage.

  13. Biofilms in Infections of the Eye

    2015-03-01

    Full Text Available The ability to form biofilms in a variety of environments is a common trait of bacteria, and may represent one of the earliest defenses against predation. Biofilms are multicellular communities usually held together by a polymeric matrix, ranging from capsular material to cell lysate. In a structure that imposes diffusion limits, environmental microgradients arise to which individual bacteria adapt their physiologies, resulting in the gamut of physiological diversity. Additionally, the proximity of cells within the biofilm creates the opportunity for coordinated behaviors through cell–cell communication using diffusible signals, the most well documented being quorum sensing. Biofilms form on abiotic or biotic surfaces, and because of that are associated with a large proportion of human infections. Biofilm formation imposes a limitation on the uses and design of ocular devices, such as intraocular lenses, posterior contact lenses, scleral buckles, conjunctival plugs, lacrimal intubation devices and orbital implants. In the absence of abiotic materials, biofilms have been observed on the capsule, and in the corneal stroma. As the evidence for the involvement of microbial biofilms in many ocular infections has become compelling, developing new strategies to prevent their formation or to eradicate them at the site of infection, has become a priority.

This effect was consistent for patientsreceiving aminoglycosides (RR: 0.51; 95%CI: 0.30-0.88 or havingvancomycin doses corrected by serum levels (RR: 0.22; 95%CI:0.10-0.52. There were no cases of acute kidney injury needingdialysis. Limitations: Studies lacked a standardized definition fornephrotoxicity. Conclusions: Teicoplanin and vancomycin are equallyeffective; however the incidence of nephrotoxicity and other adverseevents was lower with teicoplanin. It may be reasonable to considerteicoplanin for patients at higher risk for acute kidney injury.

    2017-04-01

    Full Text Available Epidemic viral conjunctivitis caused by adenovirus is the most common infectious conjunctivitis. The exact incidence of adenoviral conjunctivitis is still poorly known, but there are two well-defined adenoviral keratoconjunctivitis clinical syndromes: epidemic keratoconjunctivitis (EKC and pharyngoconjunctival fever (PCF. Epidemic keratoconjunctivitis is also the most severe form and presents with watery discharge, hyperemia, chemosis and ipsilateral lymphadenopathy. Diagnosis is mainly clinical, but its etiology can be confirmed using cell cultures, antigen detection, polymerase chain reaction or immune-chromatography. Multiple treatments have been tried for this disease, but none of them seem to be completely effective. Viruses are resistant to desiccation and certain common surface disinfectants. Prevention is the most reliable and recommended strategy to control this epidemic infection. Global epidemic surveillance system definitely needs to be established to monitor and analyze the epidemic conjunctivitis in the future. There is clearly a need for the national and the military public health institutions to work together on guidelines to handle future challenges.

    A prospective study was conducted to determine the frequency and distribution of bacterial and viral pathogens in infants hospitalized with suspected sepsis and to evaluate the potential of virus detection for improving patient management. A causative organism was detected in 157 (67%) of 233 previously healthy infants less than 3 months of age, who had been hospitalized for suspected sepsis: 19 (8%) had bacterial infections, 135 (58%) had viral infections, and 3 (1%) had mixed viral-bacterial infections. Viral infections occurred in a seasonal pattern: enteroviruses were responsible for most of the hospitalizations during summer and fall (65/110; 63%) and respiratory syncytial and influenza A viruses were responsible for most of the infections during winter (44/81; 55%). In contrast, bacterial infections were not seasonally distributed. Virus was detected in 33% of the 138 infected infants within 24 hours, and in 64% within 3 days. We conclude that viral infections are prevalent among infants hospitalized for suspected sepsis, and most can be detected early enough to influence patient management.

    The present study was conducted to determine the prevalence and clinical features of dientamoebiasis in patients presumed to be infected with intestinal parasites. A total of 168 patients were examined for D. fragilis using microscopy (after Wheatley's trichrome staining) and culture (using modified Boeck and Drbohlav's medium). D. fragilis trophozoites were detected in 15 samples (8.9%) examined using trichrome staining and in 50 samples (29.8%) by culture method. Other enteric parasites were common in the study population as 48.8% of patients (82/168) were found harboring intestinal parasites. Blastocystis hominis was the most common, identified in 33.3% (56/168) of the samples. Giardia lamblia was detected in 17.9% (30/168) and E. histolytica/E. dispar in 11.9% (20/168). The symptoms most frequently encountered were diarrhea, abdominal pain and weight loss and fatigue. Diarrhea and abdominal pain were significantly more frequent in patients with dientamoebiasis compared to non pathogenic cases (P fragilis compared to 50% of patients infected with G. lamblia, while abdominal pain was encountered with D. fragilis in 41% compared to 33.3% with G. lamblia. These differences were insignificant (P > 0.05).

    Community-onset blood stream infection (C-BSI) is an important cause of sepsis. The urinary tract is an important source for C-BSI. Urinary catheters are a recognized risk factor. Blood culture is the critical diagnostic test. Prompt effective antimicrobial therapy is a key intervention. We reviewed practice in relation to patients presenting with suspected C-BSI. To review practice in relation to patients presenting with suspected C-BSI. Patients were those with blood cultures (BC) submitted from the emergency department over 4 weeks. Details were recorded from laboratory and patient records. Data were analysed in SPSS. BC were taken from 201 patients. Suspected source was respiratory (32.8%), urine (14.9%) or other (52.3%). 9 (4.5%) patients had urine catheters. Urine was the suspected source of infection in five of these. Bacteriuria was present in seven of these nine from whom urine samples were submitted though it was polymicrobial in all but 2. Median time from registration to first administration of an antimicrobial was 226 min and was broadly guideline compliant in 121 (80.7%) of 151 patients who received treatment. BC were positive in 17 (8.5%) of which 10 (5.0%) were significant (mainly Escherichia coli). Suspected C-BSI is common. E. coli is the leading pathogen. Urine is a common suspect source. Urinary catheters are present in 4.5%. Median time to first dose of antimicrobial treatment is almost 4 h suggesting scope to expedite patients transition from presentation to intervention.

    Full Text Available Numerous viral and bacterial pathogens have been reported causing acute respiratory tract infection (ARTI. Nasopharyngeal swab (NPS specimens from 351 patients (278 children, 73 adults with suspected upper and lower ARTI were submitted during the study period from Jan. 2005 to Dec. 2006. Organism-specific nucleic acids were detected using TemPlex technology (ResPlex I and II, Genaco Biomedical Products, Huntsville, AL. Amplified products were identified using a suspension array for multiplex detection performed on a Luminex 100 instrument (Luminex, Austin, TX. A total of 221 viral and bacterial respiratory agents were detected in 148 patients (135 [48.5%] of the 278 children and 13 [17.8%] of the 73 adults with suspected ARTI. A single respiratory pathogen was detected in 89 patients [25.35%], whereas mixed infection with two or three pathogens was found in 59 [16.8%] of 351 suspected patients. S. pneumonia was the most frequently isolated strain (54 [15.3%] of 351 patients, followed by H. influenzae (37 [10.5%], rhinoviruses (35 [9.9%], influenza A virus (23 [6.5%], enteroviruses (19 [5.4%], hMPV (14 [3.9%], PIV-1 (12 [3.4%], PIV-3 (11 [3.1%], RSV (10 [2.8%], and influenza B virus (6 [1.7%].

    A disseminated Lactobacillus rhamnosus GG ATCC 53103 infection was suspected in a 6 day-old newborn with intrauterine growth restriction (IUGR) symptoms, treated empirically with antibiotics and given L. rhamnosus GG with the aim of preventing antibiotic-associated gastrointestinal complications. The level of C-reactive protein on day 5 compared with day 2 was increased in spite of negative urine and cerebrospinal fluid cultures. The blood sampled on day 6 was found to be positive for lactobacilli, and the isolate was pre-identified as L. rhamnosus or Lactobacillus casei on day 11. The strain identity was then verified as L. rhamnosus GG through PCR and 16S rRNA sequencing. Genotyping with the rep-PCR and AFLP methods confirmed the 100% genetic similarity for both the strain isolated from patient blood and the probiotic product. The newborn became touch-sensitive, cried a lot, had worsening laboratory test results, and increased inflammation parameters, but no fever was observed. After a further 9 days of antibiotic therapy, blood cultures became negative, and laboratory tests improved on day 25. The patient was discharged from the hospital after 27 days. IUGR with a possible link to L. rhamnosus GG bacteraemia might be a new potential risk group, beside patients with organ failure, immunocompromised status and dysfunctional gut barrier mechanisms, for which safe use of probiotics needs careful attention. Universally accepted or improved guidelines for the safer administration of probiotics in risk groups are urgently needed. This report should not discourage the use of probiotics, but should highlight the need for their careful use in IUGR patients.

    Diagnosis of early neonatal infection remains an emergency. Since clinical symptoms and biological markers are neither sensitive nor specific, many newborns suspected of infection undergo biological analysis and empirical antibiotic treatment while awaiting results. Recent studies underline the benefit of using procalcitonin (PCT) to differentiate inflammatory diseases and viral infections from bacterial infections. Joram shows that it is possible to go beyond the physiological peak of PCT in the first days of life by measuring PCT concentration in cord blood. The aim of this prospective study was to evaluate a new algorithm integrating the value of PCT in blood cord for taking care of newborns who have suspected infection. The diagnostic value of the new algorithm was compared to the diagnostic value of the algorithm currently in use, by analyzing a 9-month prospective database of 1267 newborns suspected of infection. Infection status was established with the ANAES definition and clinical progression. Each infected newborn (n=8) would have been treated without delay with the current algorithm (based on ANAES guidelines) and this new algorithm. The new algorithm had the same diagnostic value as the current algorithm (P=0.5) with 87.5% sensitivity (95%CI [52-98]) versus 100% (95%CI [87-100]) and 87.4% specificity (95%CI [85-90]) versus 83.8% (95%CI [81-86]). Fewer biological analyses 13.1% (95%CI [11-16]) versus 42.2% (95%CI [39-45]) were performed with the PCT cord-guided algorithm than with the current algorithm (P<0.05), leading to a 64.2% cost reduction. Antibiotics were significantly less used with the new algorithm: 13.1% (95%CI [11-16]) versus 16.7% (95%CI [14-19]). PCT in cord blood could become a new and efficient marker to help neonatologists take care of newborns suspected of infection. These results must be confirmed by a larger multicenter prospective study. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Foot ulcer with suspected infection is one of the most common reasons for hospitalization and a major factor contributing to morbidity and high healthcare-related expenses among diabetic patients. Many patients will require amputation; however, major amputation is associated with an alarmingly high 5-year mortality rate. In this study, we assess the diagnosis and management of suspected foot infection in diabetic patients using dual-isotope (DI) single-photon emission computed tomography/computed tomography (SPECT/CT) compared with conventional imaging. The diagnostic accuracy in and management of 227 patients who had undergone DI SPECT/CT was compared with that of 232 similar patients who had undergone conventional imaging including plain radiography, CT, planar bone scanning, planar indium-111 white blood cell scanning, and MRI. The duration of hospitalization was additionally compared between these two groups of patients after excluding patients with other active comorbidities. Soft-tissue infection, osteomyelitis with or without soft-tissue infection, and other bony pathologies were more accurately and confidently identified with DI SPECT/CT than with conventional imaging. DI SPECT/CT use was associated with significantly fewer major amputations and more selective bony resection as well as with shorter duration of hospitalization when compared with conventional imaging. In this large population of diabetic patients with suspected foot infection DI SPECT/CT was more accurate in diagnosing and localizing infection compared with conventional imaging. In addition, DI SPECT/CT provided clear guidance and promoted many limb salvage procedures. Of equal importance to health economics, DI SPECT/CT use was associated with considerably reduced length of hospitalization compared with conventional imaging.

    We investigated if three-phase Tc-99m HMPAO WBC scintigraphy (TP-WBC) to detect infection in patients with knee protheses has more additive values than conventional Tc-99m HMPAO WBC scintigraphy (C-WBC). Thirty patients (M: F=8: 22, Age; 69.26.2 yrs) with suspected knee prothesis infection were enrolled in our study. We performed Tc-99m HMPAO WBC scintigraphies at 4 different time points after the injection of the labeled leukocytes; Immediately after the bolus injection (perfusion phase image), 1 min (blood-pool phase image), and 1 and 3 hours (delayed static images, C-WBC). The final diagnosis of infection was based on surgical, histologic, and bacteriologic data and other follow-up studies. We compared with diagnostic performance between TP-WBC and C-WBC. Twenty patients (66.7%) finally had infected prothesis, the other ten (33.3%) didn't have it. C-WBC showed 85.0% of sensitivity, 30.0% of specificity, 70.8% of PPV, 50.0% of PNV, and 66.7% of accuracy. TP-WBC also showed 95.0% of sensitivity, 30.0% of specificity, 73.1 % of PPV, 75.0% of PNV, and 73.3% of accuracy. TP-WBC demonstrated higher sensitivity and accuracy than C-WBC. Three-phase images of Tc-99m HMPAO WBC scintigraphy may have more additive value to detect infection in patients with suspected knee prosthesis infection.

    Solid organ transplant (SOT) recipients are at high risk of developing infections and malignancies. 18F-FDG PET/CT may enable timely detection of these diseases and help to ensure early intervention. We aimed to describe the clinical utility of FDG PET/CT in consecutive, diagnostic unresolved SOT recipients transplanted from January 2004 to May 2015. Recipients with a post-transplant FDG PET/CT performed as part of diagnostic work-up were included. Detailed chart reviews were done to extract relevant clinical information and determine the final diagnosis related to the FDG PET/CT. Based on á priori defined criteria and the final diagnosis, results from each scan were classified as true or false, and diagnostic values determined. Among the 1,814 recipients in the cohort, 145 had an FDG PET/CT performed; 122 under the indication of diagnostically unresolved symptoms with a suspicion of malignancy or infection. The remaining (N = 23) had an FDG PET/CT to follow-up on a known disease or to stage a known malignancy. The 122 recipients underwent a total of 133 FDG PET/CT scans performed for a suspected malignancy (66 %) or an infection (34 %). Sensitivity, specificity, and positive and negative predictive values of the FDG PET/CT in diagnosing these conditions were 97, 84, 87, and 96 %, respectively. FDG PET/CT is an accurate diagnostic tool for the work-up of diagnostic unresolved SOT recipients suspected of malignancy or infection. The high sensitivity and NPV underlines the potential usefulness of PET/CT for excluding malignancy or focal infections in this often complex clinical situation.

    Arboviruses impose a serious threat to public health services. We report a case of a patient returning from a work trip to the Amazon basin with myalgia, arthralgia, fever, and headache. During this travel, the patient visited riverside communities. Both dengue and Chikungunya fevers were first suspected, tested for, and excluded. Mayaro fever was then confirmed by reverse transcription polymerase chain reaction followed by next-generation sequencing and phylogenetic reconstruction. The increased awareness of physicians and consequent detection of Mayaro virus in this case was only possible due a previous surveillance program with specific health personnel training about these neglected arboviruses.

    Herpes zoster ophthalmicus (HZO) is a clinical manifestation of the reactivation of latent varicella zoster virus (VZV) infection and is more common in people with diminished cell-mediated immunity. Lesions and pain correspond to the affected dermatomes, mostly in first or second trigeminal branch and progress from maculae, papules to vesicles and form pustules, and crusts. Complications are cutaneous, visceral, neurological, ocular, but the most debilitating is post-herpetic neuralgia. Herpes zoster ophthalmicus may affect all the ophthalmic structures, but most severe eye-threatening complications are panuveitis, acute retinal necrosis (ARN) and progressive outer retinal necrosis (PORN) as well. Antiviral medications remain the primary therapy, mainly useful in preventing ocular involvement when begun within 72 hours after the onset of the rash. Timely diagnosis and management of HZO are critical in limiting visual morbidity. Vaccine in adults over 60 was found to be highly effective to boost waning immunity what reduces both the burden of herpes zoster (HZ) disease and the incidence of post-herpetic neuralgia (PHN).

    The purpose of this study was to assess the incidence of nondiagnostic computed tomography-guided lung biopsy results, stratified by biopsy indication, and determine the final diagnosis in such cases. Following institutional review board approval, pathology results from CT-guided lung biopsies over a 5-year period at 2 institutions were categorized as diagnostic or nondiagnostic. Each biopsy's indication was categorized as being for a lesion considered likely to be cancer, infection, or uncertain. For all nondiagnostic biopsies, the medical chart was reviewed to determine the final clinical diagnosis. A total of 660 biopsies were evaluated, 139 (21%) of which were nondiagnostic. Of these 139 patients, the final clinical diagnosis was infection in 37%, cancer in 30%, and a benign noninfectious diagnosis in 10%; 23% remained undiagnosed at last available follow-up. Among the patients in whom there was a high pretest suspicion for cancer, 13% were nondiagnostic, 45% of which were cancer and 27% were infection. Among biopsies of lesions with pretest probability for both cancer and infection, 51% were nondiagnostic; on clinical follow-up these were determined to be infection in 34% and cancer in 14%. When there was high pretest suspicion for infection, 73% were nondiagnostic, of which 13% were cancer on clinical follow-up, and 88% were infection. The rate of nondiagnostic biopsies was statistically significantly different (Pinfection. Among all nondiagnostic biopsies, regardless of indication, cancer and infection were diagnosed on follow-up in similar proportions.

    1985-12-01

    During a 2-year period, 233 infants younger than 3 months were prospectively studied to determine whether physical examination, white blood cell and band count, and urinalysis could identify infants unlikely to have serious bacterial infections. Only previously healthy infants (born at term, no perinatal complications, no previous or underlying diseases, no previous antibiotic therapy) were studied. One hundred forty-four (62%) of the 233 infants were considered unlikely to have serious bacterial infections, because they did not have physical findings consistent with ear, soft tissue, or skeletal infection, had between 5000 and 15,000 white blood cells/mm3, had less than 1500 bands/mm3, and urinalysis yielded normal findings. Eighty-nine (38%) infants did not meet one or more of these criteria and were classified as being at high risk for serious bacterial infection. Only one (0.7%) of the 144 infants in the low-risk group had a serious infection, compared with 22 (25%) of the 89 infants in the high risk group (P less than 0.0001). None of the infants in the low-risk group had bacteremia, compared with nine (10%) of the 89 infants in the high-risk group (P less than 0.0005). Neither traditional risk factors, such as age, sex, and temperature, nor other signs, symptoms, or laboratory findings were adequate predictors of serious bacterial infection. We conclude that previously healthy infants younger than 3 months with an acute illness are unlikely to have serious bacterial infection if they have no findings consistent with ear, soft tissue, or skeletal infections and have normal white blood cell and band form counts and normal urine findings.

Identification of bacterial isolates was performed with MALDI-TOF (MS-based Vitek MS system, bioMerieux. Screening for ESBLs and carbapenemases production was done with the Vitek 2 system (bioMérieux. ESBL production was confirmed using the combined disk diffusion method for cefotaxime, ceftazidime, and cefepime, all with and without clavulanic acid (Rosco. Real-time PCR and sequencing were used to characterize the resistance genes. The phylogenetic groups of E. coli were identified by a PCR-based method.Of the 94 Enterobacteriaceae isolates 46 (48.93% showed an ESBL phenotype. One Enterobacter spp isolate was ESBL-producer and meropenem-resistant. The genetic analysis showed that CTX-M was present in 89.13% (41/46 of the ESBL-producing Enterobacteriaceae, whereas TEM and SHV were detected in 56.52% (26/46 and 21.74% (10/46 respectively (47.83% of the ESBL-producing isolates were multidrug resistant (MDR. Eleven out of 30 ESBL-producing E-coli isolates were assigned to phylogroup B2, followed by groups B1 (8 isolates, A (6 isolates and D (5 isolates.The high ESBL-E rates (48.93% found in this study together with the identification of one carbapenem-resistant Enterobacter spp isolate is worrisome. Our results indicate that systems for monitoring and detection of ESBL-producing bacteria in Egyptian hospitals have to be established. Also strict hospital infection control policies with the restriction of the consumption of extended-spectrum cephalosporins are necessary.

    Full Text Available Abstract Background Methicillin resistant Staphylococcus aureus (MRSA is an increasingly common cause of nosocomial infections, causing severe morbidity and mortality worldwide, and accounting in some hospitals for more than 50% of all S. aureus diseases. Treatment of infections caused by resistant bacterial pathogens mainly relies on two therapeutic modalities: development of new antimicrobials and use of combinations of available antibiotics. Combinations of antibiotics used in the empiric treatment of infections with suspected methicillin resistant Staphylococcus aureus etiology were investigated. Methods Double (vancomycin or teicoplanin with either levofloxacin or cefotaxime and triple (vancomycin or teicoplanin + levofloxacin + one among amikacin, ceftazidime, cefepime, imipenem, piperacillin/tazobactam combinations were evaluated by means of checkerboard assay and time kill curves. Mutational rates of single and combined drugs at antimicrobial concentrations equal to the resistance breakpoints were also calculated. Results Vancomycin or teicoplanin + levofloxacin showed synergy in 16/50 and in 9/50 strains respectively, while vancomycin or teicoplanin + cefotaxime resulted synergic for 43/50 and 23/50 strains, respectively. Triple combinations, involving teicoplanin, levofloxacin and ceftazidime or piperacillin/tazobactam gave synergy in 20/25 strains. Teicoplanin + levofloxacin gave synergy in triple combinations more frequently than vancomycin + levofloxacin. For single antibiotics, mutational frequencies ranged between 10-5 and -9 for levofloxacin, cefotaxime, amikacin and imipenem, and -9 for vancomycin and teicoplanin. When tested in combinations, mutational frequencies fell below 10-9 for all the combinations. Conclusion In vitro evidence of synergy between glycopeptides, fluoroquinolones (levofloxacin and β-lactams and of reduction of mutational frequencies by combinations are suggestive for a potential role in empirical therapy

    To determine the accuracy of guided computed tomography aspiration in the detection of septic hip prosthesis before surgery. Sixty-three patients (35 women and 28 men; age range, 29-86 years; mean age, 71 years) with clinically suspected septic hip prosthesis were prospectively studied with independent review board (IRB) approval. Volume and microbiological cultures of aspirated fluid and several computed tomography imaging findings such as periprosthetic fluid collections, prosthetic acetabular malposition, and heterotopic ossification were analyzed. All patients underwent revision surgery and infection was finally diagnosed in 33 patients. Statistical comparative analysis was performed comparing computed tomography aspiration and surgical findings (95% CI; level of significance at P = 0.05 two-sided) with 70% sensitivity, 100% specificity, 84% accuracy, 100% positive predictive value, and 75% negative predictive value. Using Fisher's exact test, the presence of periprosthetic fluid collections (P = 0.001), prosthetic acetabular malposition (P = 0.025) and aspirated fluid volume (P = 0.009) were significantly higher in infected than in non-infected prostheses, whereas heterotopic ossification was not (P = 0.429). Computed tomography aspiration is accurate to preoperatively diagnose septic hip prosthesis on the basis of volume and bacterial cultures of aspirated joint fluid. Furthermore, imaging findings such as periprosthetic fluid collections and prosthetic acetabular malposition strongly suggest infected prosthesis. (orig.)

    Neisseria gonorrhoeae is a bacterium responsible for one of the classic sexually transmitted infection (STI) gonorrhea. Antibiotic resistant strains are emerging at alarming rate. Multiple sexual partners, unsafe sex and substance use habits are the main host related risk factors for acquiring the infection. Thus, this study aimed at determining the magnitude, its determinants and antimicrobial resistance profile of N. gonorrhoeae in a place where there is risk related cultural practices and relatively high HIV prevalence. A cross-sectional study was conducted on 186 STI suspected patients seen in Gambella hospital from March to July 2015. Data on socio-demographic characteristics and associated risk factors was collected using pre-designed questionnaire. Urethral or endo-cervical swabs were collected aseptically by trained nurses. Then, samples were transported to laboratory and processed within 15 min following standard microbiological culture techniques. Antimicrobial susceptibility test was performed by using Kirby-Bauer disk diffusion method. Data entry, transforming and analysis was done using SPSS version 20. In this study 11.3 % of the STI suspected patients were confirmed to have N. gonorrhoeae. The rate of infection in males was four times higher than in females accounting 16.0 and 5.0 % respectively (p = 0.049). It was also higher (18.9 %) in 20-24 years age group (p = 0.439). Alcohol intake (p = 0.013), less frequent condom use (p = 0.031), and multiple sex partners (p = 0.024) were associated with increased odds of infection. All N. gonorrhoeae isolates were susceptible to ceftriaxone and cefoxitin but all were resistant to penicillin and tetracycline. Alarmingly, 28.6 % of the isolates were resistant to ciprofloxacin. The proportion of urogenital symptoms attributable to N. gonorrhoeae was high (11 %), with highest prevalence among males and young adults. Hence, prevention efforts should consider behavioral risk reduction. Ceftriaxone

    Background TB-HIV co-infection is one of the biggest public health challenges in sub-Saharan Africa. Although there is a wealth of information on TB-HIV co-infection among settled populations in Africa and elsewhere, to our knowledge, there are no published reports on TB-HIV co-infection from pastoral communities. In this study, we report the prevalence of TB, HIV and TB-HIV co-infection among pulmonary TB suspects in the Afar Regional State of Ethiopia. Design In a cross-sectional study design, 325 pulmonary TB suspects were included from five health facilities. Three sputum samples (spot-morning-spot) were collected from each participant. Sputum samples were examined for the presence of acid fast bacilli using Ziehl–Neelsen staining method, and culture was done on the remaining sputum samples. Participants were interviewed and HIV tested. Results Of the 325 pulmonary TB suspects, 44 (13.5%) were smear positive, and 105 (32.3%) were culture positive. Among smear-positive patients, five were culture negative and, therefore, a total of 110 (33.8%) suspects were bacteriologically confirmed pulmonary TB patients. Out of 287 pulmonary TB suspects who were tested for HIV infection, 82 (28.6%) were HIV positive. A significantly higher proportion of bacteriologically confirmed pulmonary TB patients [40 (40.4%)] were HIV co-infected compared with patients without bacteriological evidence for pulmonary TB [42 (22.3%)]. However, among ethnic Afar pastoralists, HIV infections in smear- and/or culture-negative pulmonary TB suspects [7 (7.6%)] and bacteriologically confirmed pulmonary TB patients [4 (11.8%)] were comparable. On multivariable logistic regression analysis, Afar ethnicity was independently associated with low HIV infection [OR=0.16 (95% CI: 0.07–0.37)], whereas literacy was independently associated with higher HIV infection [OR=2.21 (95% CI: 1.05–4.64)]. Conclusions Although the overall prevalence of TB-HIV co-infection in the current study is high, ethnic

    To report the risk of cataract progression among primary angle closure suspects (PACS) 6 years after they underwent laser peripheral iridotomy (LPI). In the Chennai Eye Disease Incidence Study, 6 years after their baseline evaluation, 4421 subjects were examined again. As part of a detailed evaluation cataract was graded using the Lens Opacities Classification System II; progression was defined as change of cataract by two or more grades or history of cataract surgery in the 6-year period. Only bilaterally phakic subjects with less than N2 or C2 or P2 cataract at baseline with no history of any form of glaucoma, primary angle closure and pseudoexfoliation were included. There were 3205 eligible subjects. Of these, 190 had undergone LPI for PACS. In comparison to the study population, they were significantly older (pcataract surgery. The cataract progression rate was significantly greater (OR 1.7, 95% CI 1.3 to 2.4, pcataract were age (pcataract progression; LPI was a risk factor only for cortical cataract (OR 1.6, 95% CI 1.1 to 2.3, p=0.007).

    Full Text Available Nigeria is ranked in the top five countries for tuberculosis deaths worldwide. This study investigated the mycobacterial agents associated with presumptive clinical pulmonary tuberculosis (TB in Nigeria and evaluated the pattern and frequency of mycobacterial infections over twelve calendar months period.Sputum samples from 1,603 consecutive new cases with presumptive diagnosis of TB were collected from August 2010 to July 2011. All sputum samples were incubated for detection of mycobacterial growth and those with positive acid fast bacilli (AFB growth were tested to detect mycobacterium tuberculosis (MTB complex and characterized to differentiate between MTB complex species. Cultures suggestive of Non-tuberculous mycobacterial infections (NTM were sub-cultured and characterized.Of the 1,603 patients screened, 444 (28% culture-positive cases of pulmonary tuberculosis were identified. Of these, 375 (85% were due to strains of MTB complex (354 cases of M. tuberculosis, 20 M. africanum and one case of M. bovis and 69 (15% were due to infection with NTM. In contrast to the MTB complex cases, the NTM cases were more likely to have been diagnosed during the calendar months of the Harmattan dust season (OR = 2.34, 1.28-4.29; p = 0.01, and aged older than 35 years (OR = 2.77, 1.52-5.02, p = 0.0007, but less likely to have AFB identified on their sputum smear (OR = 0.06, 0.02-0.14, p<0.0001. Among those with NTM infection, cases 35 years or younger were more likely to have co-infection with HIV (3.76, 1.72-8.22; p = 0.0009 compared to those older than 35 years.The high proportion of younger patients with clinical pulmonary TB due to NTM and co-infection with HIV and the likely role of the seasonal dust exposure in the occurrence of the disease, present novel public health challenges for prevention and treatment.

    Mycoplasma genitalium has been identified as a cause of pelvic inflammatory disease (PID), a clinical syndrome associated with inflammation of the female upper genital tract and serious reproductive sequelae. As the demographic, behavioural and sexual risk profile of women with M genitalium-associated PID is not well understood, the characteristics of M genitalium-infected women presenting with clinically suspected PID were investigated. Data from 586 participants in the PID Evaluation and Clinical Health Study were analysed. Demographic, sexual history and behavioural characteristics, including age, race, marital status, education level, sexual activity, number of sexual partners, history of sexually transmitted infection (STI), bacterial vaginosis and PID, contraception use, oral and anal sex, age at sexual debut, douching practices and drug, alcohol and tobacco use, were compared between 88 women testing positive and 498 women testing negative for M genitalium by PCR in the cervix and/or endometrium. Twenty-two women with M genitalium mono-infections were compared with 172 women who tested positive for Neisseria gonorrhoeae by culture and/or Chlamydia trachomatis by PCR. Age under 25 years, douching two or more times per month and smoking were independently associated with M genitalium. Women with M genitalium mono-infections were significantly less likely to be African-American (59.1% vs 86.0%, p = 0.001) than women with N gonorrhoeae and/or C trachomatis. Women infected with M genitalium had some characteristics commonly associated with PID and other STI. The demographic, sexual and behavioural characteristics of M genitalium-positive women were similar to women with chlamydial and/or gonococcal PID.

    Escherichia coli is the most common pathogen causing Urinary Tract Infections (UTI). Data from the current National Surveillance program in Denmark (DANMAP) may not accurately represent the prevalence of resistant E. coli in primary care, because only urine samples from complicated cases may be forwarded to the microbiological departments at hospitals for diagnostic examination. The aim of this study was to assess the prevalence of resistant E. coli to the most commonly used antimicrobial agents in primary care in a consecutive sample of patients from general practice. Observational study carried out from December 2014 to December 2015. Thirty-nine general practices from The Capital Region of Denmark included adult patients with urinary tract symptoms and suspected UTI. All urine samples were sent to the central laboratory Statens Serum Institut (SSI). Significant bacteriuria was interpreted according to the European Urinalysis Standards. Susceptibility testing was performed and interpreted according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) standards. From the 39 general practices 505 patients were recruited. Completed data were obtained from 485 (96%) patients. According to the European Urinalysis Standards, 261 (54%) patients had positive bacteriuria. The most common uropathogen in patients with uncomplicated (uUTI) and complicated (cUTI) urinary tract infection was E. coli 105 (69%) and 76 (70%), respectively. Eighty-two (45%) of 181 E. coli isolates were resistant to at least one of the tested antibiotics and 50 out of 82 isolates were resistant to two or more antimicrobial agents. The highest resistance-rate was found against ampicillin 34% (95% CI 24;42) in uUTI and 36% (24;46) in cUTI. There were no differences in the distribution of resistance between uncomplicated and complicated cases. The prevalence of resistance was similar to the one reported in DANMAP 2014. In E. coli from uUTI there is high resistance rates to

    A 68-year-old man diagnosed with cT3N2 adenocarcinoma of the rectum presented with a synchronous solitary liver metastasis on CT scan. Neoadjuvant chemoradiotherapy was started to downstage the primary tumour. Resection of the rectal tumour followed 3 months after the last radiotherapy session and primary resection of the isolated liver lesion was performed in the intervening period. Histopathological assessment of the liver lesion, however, showed no malignancy, but did reveal a necrotic infection due to Enterobius vermicularis. This parasite is frequently found in the intestines, but only rarely infects the liver. The patient was subsequently treated with the anthelmintic drug mebendazole 100 mg once a week for 2 weeks. Histopathological assessment of the rectal specimen showed complete regression after neoadjuvant chemoradiotherapy without evidence of remaining E. vermicularis, suggesting pinworm eradication. The patient recovered promptly after both surgical procedures. 2015 BMJ Publishing Group Ltd.

  11. Brucella melitensis: a rarely suspected cause of infections of genitalia and the lower urinary tract

    Full Text Available We examined the clinical presentation and outcome of Brucellar infections of genitalia and the lower urinary tract through a review of the medical records of 10 cases of male patients with brucellar infections of the genitalia and lower urinary tract. The mean age of the patients with brucellosis was 49.2, (median 52, range 15-77 years. Eleven out of 17 patients were rural residents, 15 reported that they might have consumed unpasteurized dairy products and four reported occupational exposure. Symptoms onset was acute in almost all cases. Scrotal pain, epidedimal swelling and fever were the most common symptoms. The Wright test was positive in 13 patients, while Brucella sp. was isolated from blood cultures in six cases. Only two patients were found with abnormal liver ultrasonography. All patients underwent treatment with doxycycline and aminoglycoside for seven days and doxycycline alone for two months. Most of them responded to antibiotic therapy with rapid regression of symptoms. One patient failed to respond to therapy and presented necrotizing orchitis, as well as abscesses, which required orchectomy. Brucellar infections of the genitalia and lower urinary tract have no specific clinical presentation; the usual laboratory examination is not sufficient to diagnose this kind of infection, therefore it could easily be misdiagnosed. An analytical medical history (including overall dietary habits and recent consumption of non-pasteurized dairy products could indicate Brucelosis as would the persistence of symptoms despite a one-week antibiotic treatment. In general, patients afflicted by brucellar epididymoorchitis respond to Brucellosis antibiotic therapy, except for some rare cases that present necrotizing orchitis and require surgical treatment.

    To validate the APACHE II and SOFA scores in patients with suspected infection in clinical settings other than intensive care units. A secondary analysis was performed on 2,530 adult patients participating in 2 cohort studies, with suspected infection as admission diagnosis within the first 24 h of hospitalization. The performance of both scoring systems was studied in order to set calibration and discrimination, respectively, on the outcomes such as mortality, admission to Intensive Care Unit, development of septic shock, or multiple organ dysfunctions. The AUC-ROC values for mortality at discharge and on day 28 in the first cohort were around 0.50 for the SOFA and APACHE II scores; whereas for the second cohort the discrimination value was around 0.70. Calibration of both scoring systems for primary outcomes, according to Hosmer-Lemeshow test, showed p>.05 in the first cohort; while in the second cohort calibration it only showed a p>.05 in the case of the SOFA for mortality at hospital discharge. This validation study of SOFA and APACHE II scores in patients with suspected infection in-hospital units other than the Intensive Care Unit, showed no consistent performance for calibration and discrimination. Its application in emergency and in-hospital patients is limited. Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor. Published by Elsevier España.

  3. Bloodstream-To-Eye Infections Are Facilitated by Outer Blood-Retinal Barrier Dysfunction.

    Directory of Open Access Journals (Sweden)

    Phillip S Coburn

    Full Text Available The blood-retinal barrier (BRB functions to maintain the immune privilege of the eye, which is necessary for normal vision. The outer BRB is formed by tightly-associated retinal pigment epithelial (RPE cells which limit transport within the retinal environment, maintaining retinal function and viability. Retinal microvascular complications and RPE dysfunction resulting from diabetes and diabetic retinopathy cause permeability changes in the BRB that compromise barrier function. Diabetes is the major predisposing condition underlying endogenous bacterial endophthalmitis (EBE, a blinding intraocular infection resulting from bacterial invasion of the eye from the bloodstream. However, significant numbers of EBE cases occur in non-diabetics. In this work, we hypothesized that dysfunction of the outer BRB may be associated with EBE development. To disrupt the RPE component of the outer BRB in vivo, sodium iodate (NaIO3 was administered to C57BL/6J mice. NaIO3-treated and untreated mice were intravenously injected with 108 colony forming units (cfu of Staphylococcus aureus or Klebsiella pneumoniae. At 4 and 6 days postinfection, EBE was observed in NaIO3-treated mice after infection with K. pneumoniae and S. aureus, although the incidence was higher following S. aureus infection. Invasion of the eye was observed in control mice following S. aureus infection, but not in control mice following K. pneumoniae infection. Immunohistochemistry and FITC-dextran conjugate transmigration assays of human RPE barriers after infection with an exoprotein-deficient agr/sar mutant of S. aureus suggested that S. aureus exoproteins may be required for the loss of the tight junction protein, ZO-1, and for permeability of this in vitro barrier. Our results support the clinical findings that for both pathogens, complications which result in BRB permeability increase the likelihood of bacterial transmigration from the bloodstream into the eye.

    Full Text Available AIM: To investigate the spectrum and antibiotic susceptibility of bacteria isolated from patients with suspected corneal infections in Zhongshan Ophthalmic Center in South China over the past four years retrospectively. METHODS: Totally 1943 corneal scrapes from patients with corneal infections from 2010 to 2013 were cultured and processed using standard microbiological procedures to identify bacterial isolates. Simultaneously, the bacterial isolates were tested for antibiotic susceptibility to 8 antibiotics (ceftazidime, cefuroxim, cefazolin, levofloxacin, ofloxacin, neomycin, tobramycin, chloramphenicol using the Kirby-Bauer disc diffusion technique. RESULTS: Of the total 1943 scrapes, 397 (20.43% were culture-positive, of which 294 (74.06% were gram-positive (GP and 103 (25.94% were gram-negative (GN bacteria. Of the GP organisms, the most prevalent genera were Staphylococcus spp. (56.17%, n=223, Kocuria spp. (5.29%, n=21 and Micrococcus spp. (1.26%, n=5. On the other hand, the most prevalent genera were Pseudomonas spp. (12.85%, n=51, Burkholderia spp. (2.02%, n=8 and Acinetobacter spp. (1.51%, n=6 for the GN organisms. Among five antibiotics that have eye drop products, the resistant to neomycin of GP (7.82%, 95% CI: 4.72%-10.92% and GN isolates (9.71%, 95% CI: 4.01%-15.41% was lowest, while the resistant to chloramphenicol was highest (GP: 34.35%, 95% CI: 28.92%-39.78%; GN: 60.19%, 95% CI: 50.74%-69.64%. CONCLUSION: Staphylococcus spp. was the most common bacterial pathogens isolated from patients with corneal infections in this setting. High percentages of GP and GN bacteria were mostly susceptible to neomycin and highly resistant to chloramphenicol.

In a randomized, controlled intervention study, 223 adult patients admitted to the hospital because of suspicion of LRTI were included with 210 patients available for analysis. Patients were randomized......Recent studies have suggested that procalcitonin (PCT) is a safe marker for the discrimination between bacterial and viral infection, and that PCT-guided treatment may lead to substantial reductions in antibiotic use. The present objective was to evaluate the effect of a single PCT measurement...

    Echinocandins, such as anidulafungin, are the first-line treatment for candidemia or invasive candidiasis in critically ill patients. There are conflicting data on the pharmacokinetic properties of anidulafungin in intensive care unit (ICU) patients. Adult ICU patients (from 3 hospitals) receiving anidulafungin for suspected or proven fungal infections were included in the present study. Patients were considered evaluable if a pharmacokinetic curve for day 3 could be completed. Twenty-three of 36 patients (7 female and 16 male) were evaluable. The median (range) age and body weight were 66 (28 to 88) years and 76 (50 to 115) kg, respectively. Pharmacokinetic sampling on day 3 (n = 23) resulted in a median anidulafungin area under the concentration-time curve from 0 to 24 h (AUC0-24) of 72.1 (interquartile range [IQR], 61.3 to 94.0) mg · h · liter(-1), a median daily trough concentration (C24) of 2.2 (IQR, 1.9 to 2.9) mg/liter, a median maximum concentration of drug in serum (Cmax) of 5.3 (IQR, 4.1 to 6.0) mg/liter, a median volume of distribution (V) of 46.0 (IQR, 32.2 to 60.2) liters, and a median clearance (CL) of 1.4 (IQR, 1.1 to 1.6) liters · h(-1) Pharmacokinetic sampling on day 7 (n = 13) resulted in a median AUC0-24 of 82.7 (IQR, 73.0 to 129.5) mg · h · liter(-1), a median minimum concentration of drug in serum (Cmin) of 2.8 (IQR, 2.2 to 4.2) mg/liter, a median Cmax of 5.9 (IQR, 4.6 to 8.0) mg/liter, a median V of 39.7 (IQR, 32.2 to 54.4) liters, and a median CL of 1.2 (IQR, 0.8 to 1.4) liters · h(-1) The geometric mean ratio for the AUCday7/AUCday3 term was 1.13 (90% confidence interval [CI], 1.03 to 1.25). The exposure in the ICU patient population was in accordance with previous reports on anidulafungin pharmacokinetics in ICU patients but was lower than that for healthy volunteers or other patient populations. Larger cohorts of patients or pooled data analyses are necessary to retrieve relevant covariates. (This study has been registered at

    To assess the feasibility of using D-mannose, a natural food supplement, in patients with multiple sclerosis (MS) reporting recurrent urinary tract infections (UTIs) as a preventative. A single-center, open-label, feasibility study enrolled patients with MS, using and not using urinary catheters, experiencing recurrent UTIs (≥3/year or ≥2/6 months). Participants were given D-mannose powder 1.5 grams twice daily for 16-weeks and were instructed to monitor suspected UTIs at home using urine dipsticks. Diaries were used to record compliance, number of prescriptions of antibiotics received for UTIs, results of urine dipsticks and cultures. Overall, 22 patients with MS, median age 50 years (46-59) were enrolled: 10 were not using catheters and 12 were using catheters. The compliance rates for using D-mannose and dipsticks for testing suspected UTIs were 100% and 90.2%, respectively. Sixty-one episodes of suspected UTIs were recorded, 19/61 (31.1%) were confirmed UTIs and 29/61 (47.5%) prescriptions of antibiotics were made. The number of monthly proven UTIs decreased both in catheter users and non-users (P < 0.01). No adverse effects were reported. Using D-mannose in patients with MS experiencing recurrent UTIs and self-monitoring for infections is feasible and safe. Further studies are required to establish efficacy.

    Contact lens-related eye infections, which can lead to serious outcomes, including blindness, are associated with several risk factors, including sleeping in lenses, exposing lenses to water, not adhering to replacement schedules, and reusing disinfecting solution (1). In some studies, adolescent and young adult contact lens wearers have been reported to be more likely than older adult contact lens wearers to develop eye infections (2,3) and more likely to have poor contact lens hygiene practices (2). In 2015, CDC reported the number and demographics of adult contact lens wearers in the United States to define the population at risk for contact lens-related eye infections (4); however, this estimate did not include adolescents. To better understand this group of younger contact lens wearers and guide prevention efforts, a population-based survey was used to assess contact lens wear, care behaviors, risk factors, and demographics among persons aged 12-17 years (referred to as adolescents in this report), young adults aged 18-24 years, and older adults aged ≥25 years in the United States. In 2016, an estimated 3.6 million adolescents (14.5%) wore contact lenses. Of the adolescents who wore contact lenses, 85% reported at least one behavior that put them at risk for a contact lens-related eye infection, compared with 81% of young adults, and 88% of older adults. These findings can inform the creation of age-specific targeted prevention messages aimed at contact lens wearers and establish a baseline for evaluating trends in contact lens wear, care habits, and contact lens-related risk behaviors.

    To describe the clinical and microbiological features of Dientamoeba fragilis and Giardia lamblia infected patients, and to analyze the genetic variation of D. fragilis strains. For a period of two years, all stool samples collected from patients suspected of having a parasitic gastrointestinal infection were examined according to our specific triple feces test (TFT) protocol. A retrospective case-control study was performed on D. fragilis and G. lamblia infected patients. Furthermore, PCR and genotyping by restriction fragment length polymorphism (RFLP) were performed upon the former. D. fragilis (6.3%) and G. lamblia (7.1%) were the most common pathogenic protozoa isolated out of 448 patients studied. Symptoms most frequently encountered with D. fragilis and G. lamblia infection were abdominal pain (69.2% and 72.4%, respectively) and diarrhea (61.5% and 79.3%, respectively). However, patients with D. fragilis infections suffered significantly less frequently from nausea and/or vomiting, anorexia and weight loss. After treatment, all D. fragilis and G. lamblia infected patients presenting a negative TFT follow-up also reported a complete resolution of their symptoms. Only genotype 1 could be detected in D. fragilis infected patients. D. fragilis and G. lamblia were the most frequently encountered parasites in our study population. Improved diagnostic tests are essential tools to study the prevalence and pathogenesis of D. fragilis.

    Streptococcus pneumoniae is the main causative agent of acute bacterial meningitis in the world. This study aimed to detect pneumoniae infection in cerebrospinal fluid (CSF) samples of patients with suspected meningitis. In this study, 200 CSF samples in patients with suspected meningitis and with negative bacterial cultures were tested. Demographic data of patients and the laboratory analysis of CSF samples were also collected in a questionnaire. Pneumococcal capsular gene spn9802 was examined by real-time PCR technique. Of 200 CSF samples from patients with the average age of 32.1±25.3 year old, 20 were positive for S. pneumoniae in patients with the average age of 35.05±24.6. The biochemical and cytological analysis of positive samples showed significant changes, including, 39.7 mg/DL protein, 46.2 mg/DL glucose and 1173 white blood cells per microliter of CSF on average. The results of this study showed the significant pneumococcal infection in culture negative CSF samples. The majority of this infection occurred in middle-aged patients and with a higher incidence rate in the winter. It seems that the traditional methods of cultivation are not sensitive enough to detect this bacterium in CSF. Alternatively, the molecular techniques such a real-time seem to be accurate, sensitive and rapid for the detection of this agent in CSF. The cytological and biochemical findings of CSF can provide valuable clues in the diagnosis of bacterial meningitis.

    Full Text Available The speed and ease with which we recognize the faces of our friends and family members belies the difficulty we have recognizing less familiar individuals. Nonetheless, overconfidence in our ability to recognize faces has carried over into various aspects of our legal system; for instance, eyewitness identification serves a critical role in criminal proceedings. For this reason, understanding the perceptual and psychological processes that underlie false identification is of the utmost importance. Gaze direction is a salient social signal and direct eye contact, in particular, is thought to capture attention. Here, we tested the hypothesis that differences in gaze direction may influence difficult decisions in a lineup context. In a series of experiments, we show that when a group of faces differed in their gaze direction, the faces that were making eye contact with the participants were more likely to be misidentified. Interestingly, this bias disappeared when the faces are presented with their eyes closed. These findings open a critical conversation between social neuroscience and forensic psychology, and imply that direct eye contact may (wrongly increase the perceived familiarity of a face.

    Children with temporary external ventricular drains (EVD) are prone to nosocomial infections. Diagnosis of bacterial meningitis and ventriculitis in these children is challenging due to frequent blood contamination of cerebrospinal fluid (CSF) and the presence of chemical ventriculitis. The aim of this study was to compare diagnostic accuracy of presepsin (sCD14-ST), a novel biomarker of bacterial infection in CSF, to predict bacterial infection in comparison to the accuracy of established biomarkers like those demonstrated in biochemical analysis of CSF. We conducted a prospective study with 18 children with suspected bacterial meningitis or ventriculitis who had 66 episodes of disease. CSF samples were taken from external ventricular drainage. We measured presepsin in CSF, as well as CSF leukocyte count, glucose, and proteins. CSF was also taken to prove bacterial infection with culture methods or with 16S rRNA gene broad-range PCR (SepsiTest; Molzym, Germany). Infection was clinically confirmed in 57 (86%) episodes of suspected meningitis or ventriculitis. Chemical ventriculitis was diagnosed in 9 (14%) episodes of suspected meningitis or ventriculitis. Diagnostic accuracies presented as area under the curve (AUC) for sCD14-ST, leukocytes, and proteins measured in CSF were 0.877 (95% confidence interval [CI], 0.793 to 0.961), 0.798 (95% CI, 0.677 to 0.920), and 0.857 (95% CI, 0.749 to 0.964), respectively. With CSF culture, we detected bacteria in 17 samples, compared to 37 detected with broad-range PCR. It was found that presepsin was present at a significantly higher level in children with clinically proven ventriculitis than in those without meningitis or ventriculitis. Diagnostic accuracies of presepsin were superior to those of leukocytes or proteins in CSF. Presepsin-guided 16S rRNA gene PCR could be used in everyday clinical practice to improve etiological diagnosis of meningitis and ventriculitis and to prescribe more appropriate antibiotics.

    Full Text Available Abstract Background To evaluate the VersaTREK (TREK Diagnostic Systems, Cleveland, Ohio blood culture system against the Bactec9240 (BD Microbiology, Cockeysville, MD, for the recovery of bloodstream pathogens. Methods Venous blood from patients with suspected bacterial sepsis was evenly distributed into bottles of each system. Positive signals were recorded and bottles processed onto standard media for organism recovery. False positive signals were regarded if no organisms were seen on Gram stain and no growth was observed. Results 177 bottles were available for analysis; the Bactec9240 system yielded 43 positive, 134 negative results and no false positive signals. The VersaTREK system had 58 positive signals with 14 being false positives. Conclusions In our setting with high background burden of immuno-compromised patients, the VersaTREK system compared favourably with the Bactec9240 in recovering blood stream aerobic and facultative anaerobic pathogens from patients with suspected bacterial sepsis. A concern is the high false positivity rate. Due to its versatility to accommodate small and large workloads as well as using smaller volumes of blood, this system may establish itself as a useful alternative for the recovery of bloodstream pathogens.

    A suspected new enteric Sphaerospora species was believed to be directly associated with the mass mortality of yearling groupers of Epinephelus spp. in South China. The epizootic generally emerged from late September to late April of the following year. The infection prevalence and mortality rate were significantly negatively correlated with fish size. Clinical signs included anorexia, cachexia and extrusion of white pulp-like substance from anus after gentle pressure on the abdomen. Upon necropsy, severe intestinal oedema, thin and transparent intestinal wall, swollen spleen, kidney and gall bladder could be observed. Wet preparation of the infected samples showed large amount of typical disporous plasmodia of the genus Sphaerospora, but no mature spores were observed. Epidemiological investigation showed that this parasite exclusively infected Epinephelus groupers. Histopathologically, this species mainly infected the epithelium of intestine and kidney tubules and caused severe epithelia sloughing and the collapse of intestinal villus. Interestingly, this enteric myxosporidiosis did not cause severe emaciation of infected fish for mass mortality usually emerged within 2-3 days after appearance of clinical signs. The species was most genetically related to Sphaerospora fugu (89% sequence identity) and phylogenetically positioned within marine Sphaerospora lineage. This is the first report of enteric sphaerosporosis of groupers. © 2017 John Wiley & Sons Ltd.

    Full Text Available Introduction: This study aimed to evaluate the clinical profile and outcomes of adult patients screened and diagnosed with H1N1 influenza infection at a tertiary care hospital in India. Materials and Methods: This retrospective  study was conducted on all adult patients suspected of H1N1 influenza admitted at a teaching hospital during the epidemic period of January-March 2015. Patients were screened and classified into three categories of A, B, and C based on international guidelines. Home confinement was recommended for patients in category A, and subjects in category B received treatment with Oseltamivir capsules. In addition, patients in category C received inpatient treatment with oseltamivir capsules. Results: In total, 695 patients were screened for H1N1 influenza infection during the epidemic, out of whom 380 patients (54.6% were in category A, 264 (37.9% were in category B, and 51 (7.3% were in category C. Throat swabs were collected and examined for 192 ( 27.6% patients, and 59 ( 8.4% cases were positive for H1N1 infection. Conclusion: According to the results of this study, close vigilance over the symptoms of patients infected with H1N1 influenza is more important than treatment and screening of suspicious cases during the epidemics of this infection. This is a retrospective cross sectional study. Hence, there were no comparative controls. The limitation of this study is,  thus the lack of control.

    The infections due to Non-Tuberculosis Mycobacteria (NTM) are becoming an important health problem in many countries in the world. Globally, an increase in NTM infections has been reported from many countries around the world. However, limited information is available about the prevalence of NTM infections in Iran. The data of the prevalence of NTM infections were collected from databases such as PubMed, Web of science, Cochrane Library, Embase, Scopus, Iranmedex, and Scientific Information Database. Comprehensive Meta-Analysis (V2.0, Biostat) software was used to analyze the data. The meta-analyses showed that the prevalence of NTM infections was 10.2% (95% confidence interval [95% CI] 6.3-15.9) among culture-positive cases of tuberculosis (TB) in Iran. The further stratified analyses indicated that the prevalence of NTM was higher in studies that were done after year 2000. Additionally, M. simiae (43.3% [95% CI 36.8-50.0]), M. intracellucar (27.3% [95% CI 0.7-95.5]) and M. fortuitum (22.7% [95% CI 16.1-30.9]) were the most prevalent NTM species, respectively. The relatively high prevalence of NTM infections (10.2%) among culture positive cases for TB underlines the need for greater enforcement of infection control strategies. Establishment of appropriate diagnostic criteria and management guidelines for NTM diseases and expanding the number and quality of regional reference laboratories may facilitate more accurate action for prevention and control of NTM infections in Iran.

    To investigate the incidence of fungal infections after corneal transplantation to determine whether storage media supplementation with an antifungal should be considered. Adverse reactions reported to the Eye Bank Association of America through the online adverse reaction reporting system between January 1, 2007, and December 31, 2010, were reviewed to identify cases of recipient fungal infection. Data were collected regarding the donor, the donor cornea, recovery and processing, and mate culture and clinical course of the recipients. Thirty-one cases of culture-proven fungal keratitis (n = 14) and endophthalmitis (n = 17) were reported out of 221,664 corneal transplants performed using corneal tissue distributed by domestic eye banks (1.4 cases per 10,000 transplants performed). Although the annual incidence of postkeratoplasty fungal infection has not increased significantly since 2005, a trend toward an increasing rate of fungal infection has been observed. Fungal infections were more commonly reported after endothelial keratoplasty procedures (0.022%) than penetrating keratoplasty procedures (0.012%), but the difference was not statistically significant (P = 0.076). Additionally, no association was found between fungal infection after endothelial keratoplasty and whether the lamellar tissue cut was performed by the surgeon or the eye bank technician. Seventy-three percent (16 of 22) of the fungal cultures performed on the mate corneas were positive, with infection developing in 67% (10 of 15) of recipient eyes (endophthalmitis in 6 eyes and keratitis in 4 eyes). Although a nonsignificant increasing trend in the rate of fungal infection has been observed over the past 6 years, it is not sufficiently compelling to pursue antifungal supplementation of donor storage media.

    Epidemiological surveillance of leishmaniasis was conducted in a northern Amazonian region of Ecuador, in which cutaneous leishmaniasis cases were recently reported. Sand flies were captured in the military training camp, and the natural infection of sand flies by Leishmania species was examined. Out of 334 female sand flies dissected, the natural infection by flagellates was microscopically detected in 3.9% of Lutzomyia yuilli yuilli and 3.7% of Lutzomyia tortura, and the parasite species were identified as Endotrypanum and Leishmania (Viannia) naiffi, respectively. After the sand fly surveillance, specimens from cutaneous leishmaniasis (CL) patients considered to have acquired the infection in the training camp area were obtained, and the infected parasite species were identified as L. (V.) naiffi. The present study reported first cases of CL caused by L. (V.) naiffi infection in Ecuador. In addition, a high ratio of infection of Lu. tortura by L.

    Full Text Available This study aimed to detect dengue virus (DENV serotypes in serum samples obtained in Matamoros Tamaulipas, Mexico, and to determine the concordance of conventional nested reverse transcriptase polymerase chain reaction (RT-PCR and a serological test [enzyme-linked immunosorbent assay (ELISA NS1]. Here, we detected mixed infections consisting of four serotypes of DENV. The most prevalent serotype was DENV-1, followed by DENV-4. This is the first report of DENV-4 in our region. Mixed infections were also detected in 21.5% of samples, and the predominant coinfection consisted of DENV-1 and DENV-2. Therefore, continuous epidemiological surveillance of DENV in this area is required to predict future forms of dengue heterologous infections and the effect of this on health care.

    Rapid diagnosis of pulmonary tuberculosis (TB) is critical for timely initiation of treatment and interruption of transmission. Yet, despite recent advances, many patients remain undiagnosed. Culture, usually considered the most sensitive diagnostic method, is sub-optimal for paucibacillary disease. We evaluated the Totally Optimized PCR (TOP) TB assay, a new molecular test that we hypothesize is more sensitive than culture. After pre-clinical studies, we estimated TOP's per-patient sensitivity and specificity in a convenience sample of 261 HIV-infected pulmonary TB suspects enrolled into a TB diagnostic study in Mbarara, Uganda against MGIT culture, Xpert MTB/RIF and a composite reference standard. We validated results with a confirmatory PCR used for sequencing M. tuberculosis. Using culture as reference, TOP had 100% sensitivity but 35% specificity. Against a composite reference standard, the sensitivity of culture (27%) and Xpert MTB/RIF (27%) was lower than TOP (99%), with similar specificity (100%, 98% and 87%, respectively). In unadjusted analyses, culture-negative/TOP-positive patients were more likely to be older (PDNA sequencing exhibit differential growth in culture. These findings suggest that the TOP TB assay is accurately detecting M. tuberculosis DNA in the sputum of culture-negative tuberculosis suspects. Our results require prospective validation with clinical outcomes. If the operating characteristics of the TOP assay are confirmed in future studies, it will be justified as a "TB rule out" test.

    2017-01-01

    Larvae of the eye fluke, Diplostomum, emerge from snails and infect fish by penetrating skin or gills, then move to the lens where they may impair the vision of the fish. For the fluke to reproduce, a bird must eat the infected fish, and it has been suggested that they therefore actively manipulate...... the fish’s behaviour to increase the risk of predation. We found that round gobies Neogobius melanostomus, a species that was recently introduced to the Kalmar Sound of the Baltic Sea, had an eye fluke prevalence of 90–100%. We investigated how the infection related to behavioural variation in round gobies....... Our results showed that the more intense the parasite-induced cataract, the weaker the host’s response was to simulated avian attack. The eye flukes did not impair other potentially important anti-predator behaviours, such as shelter use, boldness and the preference for shade. Our results...

    Full Text Available Invasive fungal infections (IFI are a heterogeneous group of diseases, whose clinical significance is increased due to large number of cancerpatients, patients with aplastic anemia, congenital or acquired immunity defects. Morbidity and mortality due to fungal infection remain high, and the available diagnostic methods do not always allow timely detect and isolate infection pathogen. Microbiological and histological examination of biopsy material is the “gold standard” of IFI diagnostic, but in practice it is often associated with high risk for patients. Reliable nonculture methods of early IFI detection needed to improve current diagnostic and allowing an earlier decision of specific antifungal therapy. This article presents the advantages and limitations of one of these tests. In recent years, many articles and reviews about circulating (1→3β-D-glucan (BDG detection (major cell wall component of most pathogenic fungi has appeared in the available literature. Despite that this test has a high diagnostic value, to recommend it for routine use in children with febrile neutropenia is premature. This test is less useful in making timely decision about diagnosis and start of antifungal therapy because of moderate sensitivity and specificity, the lack of evaluation criteria in children, late results (if detected in reference laboratory and cost. BDG detection results can be interpreted only in conjunction with clinical course and data of routine laboratory and radiological methods.

    Lower-respiratory-tract infection is one of the most common acute illnesses managed in primary care. Few placebo-controlled studies of antibiotics have been done, and overall effectiveness (particularly in subgroups such as older people) is debated. We aimed to compare the benefits and harms of amoxicillin for acute lower-respiratory-tract infection with those of placebo both overall and in patients aged 60 years or older. Patients older than 18 years with acute lower-respiratory-tract infections (cough of ≤28 days' duration) in whom pneumonia was not suspected were randomly assigned (1:1) to either amoxicillin (1 g three times daily for 7 days) or placebo by computer-generated random numbers. Our primary outcome was duration of symptoms rated "moderately bad" or worse. Secondary outcomes were symptom severity in days 2-4 and new or worsening symptoms. Investigators and patients were masked to treatment allocation. This trial is registered with EudraCT (2007-001586-15), UKCRN Portfolio (ID 4175), ISRCTN (52261229), and FWO (G.0274.08N). 1038 patients were assigned to the amoxicillin group and 1023 to the placebo group. Neither duration of symptoms rated "moderately bad" or worse (hazard ratio 1.06, 95% CI 0.96-1.18; p=0.229) nor mean symptom severity (1.69 with placebo vs 1.62 with amoxicillin; difference -0.07 [95% CI -0.15 to 0.007]; p=0.074) differed significantly between groups. New or worsening symptoms were significantly less common in the amoxicillin group than in the placebo group (162 [15.9%] of 1021 patients vs 194 [19.3%] of 1006; p=0.043; number needed to treat 30). Cases of nausea, rash, or diarrhoea were significantly more common in the amoxicillin group than in the placebo group (number needed to harm 21, 95% CI 11-174; p=0.025), and one case of anaphylaxis was noted with amoxicillin. Two patients in the placebo group and one in the amoxicillin group needed to be admitted to hospital; no study-related deaths were noted. We noted no evidence of

    Full Text Available Helicobacter pylori, a Gram-negative bacterium found in the human stomach, is often present in patients with chronic gastritis. Traditional treatment for H. pylori infection includes metronidazole or clarithromycin, both being associated with development of resistance. In this retrospective report, we describe our clinical experience using a multi-drug treatment regimen for pediatric H. pylori that included nitazoxanide, a newer nitrothiazole benzamide compound used in treating intestinal protozoa infections. Charts were identified for patients who were treated between January 1, 2008 and December 31, 2013 with an ICD-9-CM code 041.86 (H. pylori and who underwent elective endoscopy. All patients were exposed to nitazoxanide for 3 days plus azithromycin, and cefixime (or another 3rd-generation oral cephalosporin for 7-10 days, plus a proton pump inhibitor for 30 days. The clinical cure criteria were predefined. There were 127 individual occurrences or cases identified for inclusion in the review, with 111 occurrences meeting the inclusion criteria. The success rate or clinical cure for the new therapy combination prescribed as defined prior to the chart review was 99 out of 111 cases (89.2%. There were no serious adverse events observed or reported during the treatment of any patient. Approximately 10% of patient charts reflected minor complaints of nausea, vomiting or abdominal cramps during the time of active drug therapy. Nitazoxanide appears to be an effective and well-tolerated option for use in combination with other agents to treat H. pylori-induced gastritis.

    Bronchoscopy with bronchoalveolar lavage (BAL) and respiratory tract biopsies are important tools for diagnosing fungal infections in children with cancer and hematopoietic stem cell transplant (HSCT) recipients. Our objective was to evaluate the impact of BAL and respiratory tract biopsies on the management of suspected fungal infections in oncology and HSCT patients. We retrospectively reviewed the medical records of oncology and HSCT patients with possible, probable, or proven fungal infection of the respiratory tract and determined whether BAL or biopsy following computed tomography (CT) prompted a change in management. Among 101 patients (0.5-29 years of age), 24 underwent a BAL and 31 had biopsies (27 lung and 4 sinus). The remaining 46 patients had CT scans only. Of these, there were radiographic findings suggestive of a fungal infection in 38 patients (83%). Thirty of these 38 patients (79%) had a change in management. BAL provided a diagnosis in 6 of 24 patients (25%). There was a change in management in 2 of the 6 (33%). Respiratory tract biopsy provided a diagnosis in 12 of 31 patients (39%). Biopsy results led to a change in management in 4 of the 12 patients (33%). Significant postoperative morbidity attributed to biopsy occurred in 3 of 31 patients (10%); 2 patients had pneumothorax requiring chest tube and intubation and a patient had prolonged intubation. BAL and biopsy in children with an oncological diagnosis or those undergoing HSCT only infrequently lead to changes in management in the era of empiric therapy with broad-spectrum anti-fungal agents. © 2015 Wiley Periodicals, Inc.

    Two dairy goat farms with high level of lameness in lactating animals were presented for further investigation. Farm 1 and Farm 2 presented with 37 and 67% morbidity, respectively. Both farms had an all year round indoor system, feeding ad libitum concentrate with forage available at all times. The lameness was found to be based in the foot. Previous treatments consisting of biweekly footbathing with zinc sulphate, spraying lesions with oxytetracycline spray and packing lesions with copper crystals on a single occasion and single injections with long acting oxytetracycline had not been successful. Mild cases had signs of haemorrhaging in the white line or on the sole of the foot. Moderate cases showed under running of the wall horn or small areas of exposed sole corium. Severe cases would consist of horn or wall separation with the corium exposed and infected. In extreme cases only the wall horn of the claw remained, with a large area of necrotic tissue in the centre and no healthy corium visible. Only one animal was seen to have interdigital lesions. Polymerase chain reaction (PCR) and culture of swabs taken from exposed corium and the interdigital space were negative for Dichelobacter nodosus but PCR for treponemes were positive in both the adults and the youngstock tested. Due to the high level of concentrate in the diet of these goats, nutrition was thought to contribute to the problem. Transcutaneous rumen fluid samples were taken and pH was measured on both farms, with 35% of the samples below pH value 5.5. No definite diagnosis could be made. However, the results suggest both treponemes and nutrition play a role in the aetiology of the lameness. The initial sole or wall horn lesions were thought to be secondarily infected by treponemes. Further investigation is needed to definitively diagnose the cause and contributing factors for this lameness.

    Jia-Xu Chen

    Full Text Available BACKGROUND: Food-borne helminthiases (FBHs have become increasingly important due to frequent occurrence and worldwide distribution. There is increasing demand for developing more sensitive, high-throughput techniques for the simultaneous detection of multiple parasitic diseases due to limitations in differential clinical diagnosis of FBHs with similar symptoms. These infections are difficult to diagnose correctly by conventional diagnostic approaches including serological approaches. METHODOLOGY/PRINCIPAL FINDINGS: In this study, antigens obtained from 5 parasite species, namely Cysticercus cellulosae, Angiostrongylus cantonensis, Paragonimus westermani, Trichinella spiralis and Spirometra sp., were semi-purified after immunoblotting. Sera from 365 human cases of helminthiasis and 80 healthy individuals were assayed with semi-purified antigens by both a protein microarray and the enzyme-linked immunosorbent assay (ELISA. The sensitivity, specificity and simplicity of each test for the end-user were evaluated. The specificity of the tests ranged from 97.0% (95% confidence interval (CI: 95.3-98.7% to 100.0% (95% CI: 100.0% in the protein microarray and from 97.7% (95% CI: 96.2-99.2% to 100.0% (95% CI: 100.0% in ELISA. The sensitivity varied from 85.7% (95% CI: 75.1-96.3% to 92.1% (95% CI: 83.5-100.0% in the protein microarray, while the corresponding values for ELISA were 82.0% (95% CI: 71.4-92.6% to 92.1% (95% CI: 83.5-100.0%. Furthermore, the Youden index spanned from 0.83 to 0.92 in the protein microarray and from 0.80 to 0.92 in ELISA. For each parasite, the Youden index from the protein microarray was often slightly higher than the one from ELISA even though the same antigen was used. CONCLUSIONS/SIGNIFICANCE: The protein microarray platform is a convenient, versatile, high-throughput method that can easily be adapted to massive FBH screening.

    Hepatitis B virus (HBV) infection is a major cause of severe liver diseases including fibrosis, hepatocellular carcinoma (HCC) and cirrhosis related end stage liver diseases (ESLD) in mankind. It is a common belief that infectious diseases have historically been responsible for the massiveness of war-related deaths, so the aim of this study was to estimate the prevalence of HBV infection and to demonstrate the various socio-economic, demographic and possible risk factors related to HBV infection among the conflict-affected peoples due to war against terrorism in North Waziristan. Blood samples were collected from total 790 suspected individuals from the conflict-affected population of North Waziristan and were analyzed initially tested for the presence of HBsAg, HBeAg antigens, Anti-HBc and Anti-HBs antibodies using ELISA methods. All the positive samples were tested by real time PCR to confirm the presence of HBV DNA in ELISA positive specimens. Total of 126 (15.94%) samples were found positive for HBV DNA by real-time PCR. Among these positive subjects, 95 (75.5%) were males while 31 (24.5%) were females in a ratio of approximately 3:1. High HBV prevalence (41.26%) was observed among the subjects of subdivision Miran Shah relating to the high frequency of military activities against terrorism as compared to Mir Ali subdivision (35.7%) and Razmak subdivision (19.8%). Among the age groups, high prevalence (38.88%) was observed in age group 21-30 as compared to children and in older age groups. The modes of HBV transmission in this area was associated with re-uses of contaminated needles/syringes in medical care, barbers shops, sexual exposure and tattooing are the principal causal risks factors. Furthermore HBV infection was significantly higher in people with low socioeconomic status, in illiterate persons and in drivers. Our results indicate high prevalence rate of HBV infection in young subjects obviously confirms the entire absence of any program to fight HBV

    Thanks to its sensitivity and its ease of use in the field, the card agglutination test for trypanosomiasis (CATT) is widely used for serological screening of Trypanosoma brucei gambiense human African trypanosomiasis (HAT). Positive subjects are then examined by microscopy to confirm the disease. However, the CATT exhibits false-positive results raising the question of whether CATT-positive subjects who are not confirmed by microscopic detection of trypanosomes (SERO) are truly exposed to T.b. gambiense infection. For this purpose, we applied microsatellite genotyping on DNA extracted from blood of both HAT confirmed patients and SERO subjects in Guinea and Côte d'Ivoire since microsatellite genotyping has proved useful for the study of T.b. gambiense genetic diversity. Problems of amplification failures raise the question of the sensitivity of microsatellite markers when applied on biological samples especially from SERO subjects for who low blood parasitaemia are suspected. Nevertheless, we have shown that the trypanosomes from SERO individuals that have been genotyped belong to T.b. gambiense group 1 and were identical to those found in HAT patients. These results constitute the first evidences that at least some SERO are indeed infected by T.b. gambiense group 1 and that they may constitute a human reservoir of parasite in HAT foci. Whether these individuals should undergo treatment remains an open question as long as their role in HAT transmission is unknown. Our results strongly recommend the follow-up of such subjects to improve control strategies. Copyright © 2011 Elsevier B.V. All rights reserved.

    Catheter-related blood stream infections (CR-BSIs) are estimated to occur in 80,000 patients in intensive care units (ICUs) each year in the United States. We sought to determine the clinical utility of vascular catheter cultures in critically ill patients with suspected CR-BSI. We reviewed retrospectively all positive (≥15 colony forming units/roll) vascular catheter tip cultures (CTCs) documented over a four-year period in the ICUs of two hospitals. A CR-BSI was defined as matching positive blood and catheter cultures. The time interval between catheter removal and blood culture was recorded. A total of 1,391 CTCs were obtained, of which 468 (34%) were positive and 143 (31% of the positive cultures) were associated with a diagnosis of CR-BSI. In 133 of these 143 cases (93%), the positive blood culture was obtained before or within 24 h after catheter removal and dictated antibiotic therapy. In only 10 of 143 cases (7%) did catheter removal and culture significantly (>1 day) precede the positive blood culture. In 55% of the CR-BSI cases, the catheter was removed empirically and close to the time of blood culture (-1.3±19.0 h). In the remaining 45%, the catheter was removed clinically (after a blood culture was positive), and this action was more remote in time (23.6±19.4 h; p<0.001 vs. empiric removal). Total microbiology laboratory costs for the CTCs were $75,300, and 600 microbiology technician hours were required. In an ICU patient population, only about one-third of vascular catheter cultures were positive, and only about one-third of the positive CTCs were associated with CR-BSI. Ninety-three percent of all CR-BSIs were identified by bacteremia either before or coinciding with catheter removal, and the results of the blood culture dictated antimicrobial therapy. Because CTCs rarely changed therapy, they may not be appropriate in the management of suspected CR-BSI in the ICU setting.

    To determine the type of Candida species in ocular infections and to investigate the relationship of antifungal susceptibility profile to virulence factors. Fifty isolates of yeast-like fungi from patients with keratitis, endophthalmitis, and orbital cellulitis were identified by Vitek-2 compact system and DNA sequencing of ITS1-5.8S-ITS2 regions of the rRNA gene, followed by phylogenetic analysis for phenotypic and genotypic identification, respectively. Minimum inhibitory concentration of six antifungal drugs was determined by E test/microbroth dilution methods. Phenotypic and genotypic methods were used to determine the virulence factors. Phylogenetic analysis showed the clustering of all isolates into eight distinct groups with a major cluster formed Candida parapsilosis (n = 21), which was the most common species by both Vitek 2 and DNA sequencing. Using χ2 test no significant difference was noted between the techniques except that Vitek 2 did not identify C. viswanathii, C. orthopsilosis, and two non-Candida genera. Of 43 tested Candida isolates high susceptibility to amphotericin B (39/43, 90.6%) and natamycin (43/43, 100%) was noted. While none of the isolates produced coagulase, all produced esterase and catalase. The potential to form biofilm was detected in 23/43 (53.4%) isolates. Distribution of virulence factors by heat map analysis showed difference in metabolic activity of biofilm producers from nonbiofilm producers. Identified by Vitek 2 and DNA sequencing methods C. parapsilosis was the most common species associated with eye infections. Irrespective of the virulence factors elaborated, the Candida isolates were susceptible to commonly used antifungal drugs such as amphotericin B and natamycin.

    Eye flukes of the genus Diplostomum were recorded with a prevalence of 7.4% and a mean intensity of 11.9 (range 1-75) parasites per fish in eye lenses of a total of 188 Atlantic cod, Gadus morhua, sampled in the Southeastern Baltic Sea from March 2013 to February 2014. A slight decrease of infection level, among the fish with body length ranging from 30 to 89.5 cm, was found when data were compared to a corresponding survey in the 1980s. Due to imprecise species identification of eye flukes based on morphometric analyses we present, as a baseline for further studies, rDNA sequences from a subsample of 19 eye flukes based on sequencing of a part of 18S, ITS-1, 5.8S, ITS-2 and part of 28S. We discuss the use of eye fluke recordings in Baltic cod as an environmental indicator due to the dependence of the parasite's life cycle on biotic (occurrence of snail and bird hosts) and abiotic (temperature and salinity) parameters.

    We examined the presence of virulence and antibiotic resistance genes, SCCmec types and determined the genomic diversity among ocular S. epidermidis isolates (patients-23, healthy controls-29). PCR determined the presence of antibiotic resistance genes, virulence genes and SCCmec types among all isolates. MLST and PFGE determined the genomic relatedness among them. All isolates of S. epidermidis showed resistance to at least one class of antibiotics of which 48 isolates were multidrug resistant and carried ARGs. Thirty-five isolates were methicillin resistant and carried mecA gene. Majority of the isolates were resistant to fluoroquinolones and showed mutation in gyrA, parC, and parE genes, however, few isolates showed additional novel mutations in parC gene. Of the MRSE strains, 17 strains carried SCCmec type IV, four type V, two type II, and two UT4. Seven strains carried novel combination of ccr complex and SCCmercury element, not reported earlier. All the S. epidermidis strains harbored icaA and icaD genes, 47 carried ACME operon, and 50 contained IS256. A noteworthy finding was the presence of ST179 among 43% of infected eye isolates an observation rarely reported among S. epidermidis. PFGE and MLST analysis showed genomic diversity among them. Statistical analysis suggests that few healthy conjunctiva isolates had characteristics similar to infected eye isolates. S. epidermidis strains carrying mecA gene are multidrug resistant, virulent and diverse irrespective of sources of isolation. IS256 cannot be used as marker to differentiate isolates of infected eye from healthy conjunctiva. PMID:28824564

    In 2015, the Centers for Disease Control and Prevention (CDC) and the American Academy of Ophthalmology (AAO) released clinical advisories on rising cases of ocular syphilis. We examined the association between eye disease and syphilis infection among primary care and sexually transmitted infection (STI) clinic patients attending an urban lesbian, gay, bisexual, transgender (LGBT) health center. We conducted a retrospective medical record review of all patients who underwent syphilis testing at Howard Brown Health between 1 January 2010 and 31 December 2015. Confirmed eye diagnosis was based on International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes for conjunctivitis, uveitis, keratitis, retinitis, and red eye. Demographic information, syphilis treatment, HIV status, and high-risk behaviors were abstracted. Syphilis diagnosis was defined by available laboratory data (enzyme immunoassay [EIA], rapid plasma reagin [RPR] titer, fluorescent treponemal antibody absorption [FTA-Abs], Treponema pallidum Ab). Multivariable logistic regression with robust variance was used to identify independent associations. During the study period, 71,299 syphilis tests were performed on 30,422 patients. There were 2288 (3.2%) positive syphilis tests. Seventy-seven patients had a confirmed eye diagnosis (0.25%). Patients with eye disease had higher probability of at least one positive syphilis test (33%) compared to those without eye disease (8%) ( p < 0.01). Of patients with eye disease, 77% were men who had sex with men (MSM) and 65% were HIV-positive. Patients with eye disease had 5.97 (95% CI: 3.70, 9.63) higher odds of having syphilis compared to patients without eye disease. When adjusted for age, race, gender/sexual orientation, insurance status, and HIV status, this association between positive syphilis test and eye disease decreased but was still significant (OR 2.00, 95% CI 1.17, 3.41).

    Diagnosis of Propionibacterium acnes bone and joint infection is challenging due to the long cultivation time of up to 14 days. We retrospectively studied whether reducing the cultivation time to 7 days allows accurate diagnosis without losing sensitivity. We identified patients with at least one positive P. acnes sample between 2005 and 2015 and grouped them into "infection" and "no infection." An infection was defined when at least two samples from the same case were positive. Clinical and microbiological data, including time to positivity for different cultivation methods, were recorded. We found 70 cases of proven P. acnes infection with a significant faster median time to positivity of 6 days (range, 2 to 11 days) compared to 9 days in 47 cases with P. acnes identified as a contamination (P broth was performed. The highest sensitivity was detected for thioglycolate broth (66.3%) and the best positive predictive values for anaerobic agar plates (96.5%). A prolonged transportation time from the operating theater to the microbiological laboratory did not influence time to positivity of P. acnes growth. By reducing the cultivation time to 7 days, false-negative diagnoses would increase by 21.4%; thus, we recommend that biopsy specimens from bone and joint infections be cultivated to detect P. acnes for 10 days with a blind subculture at the end.

    Full Text Available Research is meager on canine ehrlichiosis in Colombia and it is absent in Medellín. This research aims to determine the seroprevalence of Ehrlichia canis and its distribution by sex, age, race and size in dogs diagnosed in a veterinary laboratory in Medellín, between 2012 and 2014. To the effect, a cross-sectional study was designed in 781 dogs. Overall seroprevalence of infection and specific by sex, age, size, and canine breed were calculated. In the bivariate analysis, Z test, Pearson’s chi-square test, and the Mann-Whitney U test were used. In the multivariate analysis, binary logistic regression was performed. 57 races were included, of which the most frequent were Creoles, Labradors, and French poodles; 54.9% were males, and 56.9% were adults. Overall prevalence of infection was 24.8%; highest specific seroprevalences were observed in females (25.9%, senile dogs (29.7%, and those belonging to large breeds (27.6%. The risk of infection in adult and senile dogs was two times higher than in puppies; the probability of infection was 6.4 times higher in cocker spaniels than in French bulldogs; the risk of infection in Siberian wolf, pug and Labrador was 7.8, 5.5 and 4.1 times higher than in bulldogs. High seroprevalence of canine ehrlichiosis and the identification of adult and senile dogs, and cocker spaniel, Siberian wolf, pug and Labrador breeds as of higher risk show the need to develop programs for prevention and treatment of this infection in the city.

    Complications after hip endoprosthesis operation occur with a frequency of 1-2 % after primary operation and with 3-5 % after revision arthroplasty and are even more frequent after knee arthroplasty. The differentiation between aseptic loosening and bacterial infection is very important. In aseptic loosening a one-step revision is usually possible. In case of bacterial infection, all foreign material has to be removed first to allow cure from the infection. After healing and absence of bacteria a follow-up operation is possible with insertion of a new prosthesis. Diagnosis and therapy of a painful hip or knee endoprosthesis are difficult, because patient history, clinical examination, laboratory results including microbiological investigation of puncture material and results of radiological examinations may all be inconclusive. Quite a number of nuclear medicine procedures have been published in the past to help in the differentiation between aseptic loosening and bacterial infection of a painful hip or knee endoprosthesis. No single method can be regarded as excellent and without disadvantages. In the international literature the combined leucocyte-marrow imaging has been propageted as superior technique. In Germany, combined leucocyte-marrow imaging is not available in the published form. Moreover, this technique is time consuming, cost intensive and requires direct work with blood. Therefore, infection imaging with labelled antibodies or labelled fragments of antibodies may be regarded as the method of choice for most nuclear medicine physicians. With semiquantitative evaluation a comparative diagnostic accuracy may be achieved. {sup 18}F-FDG-PET is not able to differentiate reliably between abacterial polyethylene abrasion and septic inflammation. However, with pattern recognition of the distribution of {sup 18}F-FDG around a hip prosthesis an approach with clinically acceptable results has been published.

    Diseases of soybean caused by Cercospora spp. are endemic throughout the world's soybean production regions. Species diversity in the genus Cercospora has been underestimated due to overdependence on morphological characteristics, symptoms, and host associations. Currently, only two species (Cercospora kikuchii and C. sojina) are recognized to infect soybean; C. kikuchii causes Cercospora leaf blight (CLB) and purple seed stain (PSS), whereas C. sojina causes frogeye leaf spot. To assess cryptic speciation among pathogens causing CLB and PSS, phylogenetic and phylogeographic analyses were performed with isolates from the top three soybean producing countries (USA, Brazil, and Argentina; collectively accounting for ~80% of global production). Eight nuclear genes and one mitochondrial gene were partially sequenced and analyzed. Additionally, amino acid substitutions conferring fungicide resistance were surveyed, and the production of cercosporin (a polyketide toxin produced by many Cercospora spp.) was assessed. From these analyses, the long-held assumption of C. kikuchii as the single causal agent of CLB and PSS was rejected experimentally. Four cercosporin-producing lineages were uncovered with origins (about 1 Mya) predicted to predate agriculture. Some of the Cercospora spp. newly associated with CLB and PSS appear to represent undescribed species; others were not previously reported to infect soybeans. Lineage 1, which contained the ex-type strain of C. kikuchii, was monophyletic and occurred in Argentina and Brazil. In contrast, lineages 2 and 3 were polyphyletic and contained wide-host range species complexes. Lineage 4 was monophyletic, thrived in Argentina and the USA, and included the generalist Cercospora cf. flagellaris. Interlineage recombination was detected, along with a high frequency of mutations linked to fungicide resistance in lineages 2 and 3. These findings point to cryptic Cercospora species as underappreciated global considerations for soybean

Methods The EuroNHID (European Network for Highly Infectious Diseases project collected data from 41 EDs and MADs in 14 European countries, located in the same facility as a national/regional referral centre for HIDs, using specifically developed checklists, during on-site visits from February to November 2009. Results Isolation rooms were available in 34 facilities (82,9%: these rooms had anteroom in 19, dedicated entrance in 15, negative pressure in 17, and HEPA filtration of exhausting air in 12. Only 6 centres (14,6% had isolation rooms with all characteristics. Personnel trained for the recognition of HIDs was available in 24 facilities; management protocols for HIDs were available in 35. Conclusions Preparedness level for the safe and appropriate management of HIDs is partially adequate in the surveyed EDs and MADs.

    As an immune-privileged site, the eye, and particularly the outer corneal surface, lacks resident mature immune effector cells. Physical barriers and innate mediators are the best-described effectors of immunity in the cornea. When the barriers are breached, infection can result in rapid tissue destruction, leading to loss of visual acuity and frank blindness. To determine the cellular and molecular components needed for effective adaptive immunity on the corneal surface, we investigated which immune system effectors were required for protection against Staphylococcus aureus corneal infections in mice, which are a serious cause of human eye infections. Both systemically injected and topically applied antibodies to the conserved cell surface polysaccharide poly-N-acetylglucosamine (PNAG) were effective at mediating reductions in corneal pathology and bacterial levels. Additional host factors impacting protection included intercellular adhesion molecule 1 (ICAM-1)-dependent polymorphonuclear leukocyte (PMN) recruitment, functional CD4(+) T cells, signaling via the interleukin-17 (IL-17) receptor, and IL-22 production. In germfree mice, there was no protective efficacy of antibody to PNAG due to the lack of LY6G(+) inflammatory cell coeffector recruitment to the cornea. Protection was manifest after 3 weeks of exposure to conventional mice and acquisition of a resident microbiota. We conclude that in the anterior eye, ICAM-1-mediated PMN recruitment to the infected cornea along with endogenous microbiota-matured CD4(+) T cells producing both IL-17 and IL-22 is required for antibody to PNAG to protect against S. aureus infection.

    Limited performance data from line probe assays (LPAs), nucleic acid tests used for the rapid diagnosis of tuberculosis (TB), nontuberculosis mycobacteria (NTM), and Mycobacterium tuberculosis drug resistance are available for HIV-infected individuals, in whom paucibacillary TB is common. In this study, the strategy of testing sputum with GenoType MTBDRplus (MTBDR-Plus) and GenoType Direct LPA (Direct LPA) was compared to a gold standard of one mycobacterial growth indicator tube (MGIT) liquid culture. HIV-positive (HIV(+)) individuals with suspected TB from southern Africa and South America with tuberculosis culture positive, of which 276 (72.8%) were acid-fast bacillus (AFB) smear positive. MTBDR-Plus had a sensitivity of 81.0% and a specificity of 100%, with sensitivities of 44.1% in AFB smear-negative versus 94.6% in AFB smear-positive specimens. For specimens that were positive for M. tuberculosis by MTBDR-Plus, the sensitivity and specificity for rifampin resistance were 91.7% and 96.6%, respectively, and for isoniazid (INH) they were 70.6% and 99.1%. The Direct LPA had a sensitivity of 88.4% and a specificity of 94.6% for M. tuberculosis detection, with a sensitivity of 72.5% in smear-negative specimens. Ten of 639 MGIT cultures grew Mycobacterium avium complex or Mycobacterium kansasii, half of which were detected by Direct LPA. Both LPA assays performed well in specimens from HIV-infected individuals, including in AFB smear-negative specimens, with 72.5% sensitivity for M. tuberculosis identification with the Direct LPA and 44.1% sensitivity with MTBDR-Plus. LPAs have a continued role for use in settings where rapid identification of INH resistance and clinically relevant NTM are priorities.

    "Red eye" is used as a general term to describe irritated or bloodshot eyes. It is a recognizable sign of an acute/chronic, localized/systemic underlying inflammatory condition. Conjunctival injection is most commonly caused by dryness, allergy, visual fatigue, contact lens overwear, and local infections. In some instances, red eye can represent a true ocular emergency that should be treated by an ophthalmologist. A comprehensive assessment of red eye conditions is required to preserve the patients visual function. Severe ocular pain, significant photophobia, decreased vision, and history of ocular trauma are warning signs demanding immediate ophthalmological consultation. Copyright © 2017 Elsevier Inc.

    Chalazion is a subacute granulomatous inflammation of the eyelid caused by retention of tarsal gland secretions and it's the most common inflammatory lesion of the eyelid. In cases of doubtful clinical presentation the diagnosis with a biopsy and a histopathological examination is important because it can orientate an appropriate surgical treatment. We report a case of a 64-years-old diabetic man, suspected for a spinocellular lesion of the inferior eyelid of the left eye, it resulted unexpectedly a chalazion.

    Whipple's disease is an infection caused by the Gram-positive bacillus Tropheryma whipplei. Invasion or uptake of the bacteria can occur in various parts of the body. The differential diagnoses are broad due to the wide spectrum of infection, and the disease is diagnosed based on biopsy of suspected lesions, usually in the small intestine. We present the case of a 56-year-old man with no significant prior medical history who presented with swelling and pain in the left eye. Review of systems revealed 6 months of persistent diarrhea, and intestinal biopsy revealed periodic acid-Schiff-positive macrophages.

    Full Text Available Keratitis treatment has become more complicated due to the emergence of bacterial or fungal pathogens with enhanced antibiotic resistance. The pharmaceutical applications of N-heterocyclic carbene complexes have received remarkable attention due to their antimicrobial properties. In this paper, the new precursor, 3,3'-(p-phenylenedimethylene bis{1-(2- methyl-allylimidazolium} bromide (1a and its analogous PF6 salt (1b were synthesized. Furthermore, silver(I and gold(I -N-heterocyclic carbene (NHC complexes [Ag2LBr2/Au2LBr2; 2a/3a], [(Ag2L2(PF62/(Au2L2(PF62; 2b/3b] were developed from their corresponding ligands. All compounds were screened for their antimicrobial activities against multiple keratitis-associated human eye pathogens, including bacteria and fungi. Complexes 2a and 3a showed highest activity, and the effectiveness of 3a was also studied, focusing eradication of pathogen biofilm. Furthermore, the structures of 1a, 2a and 3b were determined using single crystal X-ray analysis, 2b and 3a were optimized theoretically. The mechanism of action of 3a was evaluated by scanning electron microscopy and docking experiments, suggesting that its target is the cell membrane. In summary, 3a may be helpful in developing antimicrobial therapies in patients suffering from keratitis-associated eye infections caused by multidrug-resistant pathogens.

    Ocular lesions have been reported in patients with schistosomiasis; however, the problem with studying schistosomal infection of the human eye is that biopsies are almost impossible to take, and histopathological examination of suspicious lesions can only be undertaken post-mortem or after enucleation. This work aimed to study the possible effects and pathogenesis of schistosomiasis on the eye. This study involved 55 hamsters; five hamsters remained non-infected and the remaining 50 hamsters were infected with Schistosoma mansoni cercariae. Infected hamsters were sacrificed on weeks 8, 12, 16 and 20 post-infection (pi). Eye sections were prepared and stained for histopathological and immunohistochemical studies. Histopathological changes detected in hamsters infected after 16 and 20 weeks included looseness and oedema of the innermost retinal layers together with hyperplastic polypoid growth. Neither eggs nor granulomata were detected in eye sections throughout the experimental period. Deposition of S. mansoni antigen was revealed in 35% of infected hamsters. Later, on weeks 16 and 20 pi, moderate subepithelial conjuctival deposits and marked subchoroidal and scleral deposition were detected. In conclusion, the deposition of schistosomal antigen and immune complexes may play a pivotal role in the ocular changes that occur in schistosomiasis, even in the absence of detectable Schistosoma eggs. Schistosomiasis should be suspected in cases with unexplained ophthalmological findings, especially in endemic areas.

    Current guidelines recommend screening eye examinations for infants with microcephaly or laboratory-confirmed Zika virus infection but not for all infants potentially exposed to Zika virus in utero. To evaluate eye findings in a cohort of infants whose mothers had polymerase chain reaction-confirmed Zika virus infection during pregnancy. In this descriptive case series performed from January 2 through October 30, 2016, infants were examined from birth to 1 year of age by a multidisciplinary medical team, including a pediatric ophthalmologist, from Fernandes Figueira Institute, a Ministry of Health referral center for high-risk pregnancies and infectious diseases in children in Rio de Janeiro, Brazil. Mother-infant pairs from Rio de Janeiro, Brazil, who presented with suspected Zika virus infection during pregnancy were referred to our institution and had serum, urine, amniotic fluid, or placenta samples tested by real-time polymerase chain reaction for Zika virus. Description of eye findings, presence of microcephaly or other central nervous system abnormalities, and timing of infection in infants with confirmed Zika virus during pregnancy. Eye abnormalities were correlated with central nervous system findings, microcephaly, and the timing of maternal infection. Of the 112 with polymerase chain reaction-confirmed Zika virus infection in maternal specimens, 24 infants (21.4%) examined had eye abnormalities (median age at first eye examination, 31 days; range, 0-305 days). Ten infants (41.7%) with eye abnormalities did not have microcephaly, and 8 (33.3%) did not have any central nervous system findings. Fourteen infants with eye abnormalities (58.3%) were born to women infected in the first trimester, 8 (33.3%) in the second trimester, and 2 (8.3%) in the third trimester. Optic nerve and retinal abnormalities were the most frequent findings. Eye abnormalities were statistically associated with microcephaly (odds ratio [OR], 19.1; 95% CI, 6.0-61.0), other central

    In recent years, several research groups have developed automatic algorithms to detect diabetic retinopathy (DR) in individuals with diabetes (DM), using digital retinal images. Studies have indicated that diabetics have 1.5 times the annual risk of developing primary open angle glaucoma (POAG) as do people without DM. Moreover, DM patients have 1.8 times the risk for age-related macular degeneration (AMD). Although numerous investigators are developing automatic DR detection algorithms, there have been few successful efforts to create an automatic algorithm that can detect other ocular diseases, such as POAG and AMD. Consequently, our aim in the current study was to develop a comprehensive eye evaluation algorithm that not only detects DR in retinal images, but also automatically identifies glaucoma suspects and AMD by integrating other personal medical information with the retinal features. The proposed system is fully automatic and provides the likelihood of each of the three eye disease. The system was evaluated in two datasets of 104 and 88 diabetic cases. For each eye, we used two non-mydriatic digital color fundus photographs (macula and optic disc centered) and, when available, information about age, duration of diabetes, cataracts, hypertension, gender, and laboratory data. Our results show that the combination of multimodal features can increase the AUC by up to 5%, 7%, and 8% in the detection of AMD, DR, and glaucoma respectively. Marked improvement was achieved when laboratory results were combined with retinal image features.

    "Dancing eye syndrome", also called Kinsbourne syndrome or Opsoclonus-Myoclonus-Ataxia Syndrome (OMS) is a rare neurological disorder that in children is frequently associated to occult, low-grade neuroblastoma (NB) (>50% of the cases). OMS may also be triggered by infections and it is often associated to developmental impairment and disability. We discuss the case of a 16 months old female with acutely onset of OMS associated to occult stage III NB. OMS represents a diagnostic challenge for pediatric clinicians. The suspect of OMS imposes the search for an occult NB in order to promptly treat a life-threatening event like tumor and to prevent the neurological sequels linked to OMS.

      To describe the gross and histopathological ocular findings in a horse following suspected lightning injury.   The eyes of a 2-year-old thoroughbred gelding were clinically and histopathologically evaluated following a severe lightning storm following euthanasia because of visual impairment.   Severe corneal edema and hydrops were noted clinically oculus dexter. Indirect ophthalmoscopy revealed bilateral symmetrical raised hyporeflective peripapillary geographic lesions. Histopathologic evaluation revealed corneal edema in the right eye with normal corneal endothelium. Posterior segment evaluation revealed localized, pericentral choroidal lesions characterized by the presence of hemorrhage, early fibrosis, and minimal lymphoplasmacytic, neutrophilic, and histiocytic inflammation with spindle cell proliferation. The retinas overlying the choroidal lesions were necrotic and mostly absent. Peripheral to the focal lesion, the retina abruptly returned to normal architecture peripheral to a zone of apoptotic photoreceptors. Centrally, swollen axons extended into the optic disc.   There have been few descriptions of ocular lesions in animals following suspected lightning injury. We believe these findings to be unique because of the type of thermal injury that may be characteristic of lightening injury. We do not know whether these lesions would have progressed over time. © 2011 American College of Veterinary Ophthalmologists.

    A group of 32 Friesian and four Hereford calves, 3-4 months old with body weights between 100-120 kg, were purchased from a weaner sale. On arrival at the property the Hereford calves were treated with a combination anthelmintic containing 2 g/L abamectin and 80 g/L levamisole hydrochloride. Shortly afterwards they developed tremors and frothing from the mouth, and two died overnight. The Friesian calves were treated with the same anthelmintic on the following day, when some showed hypersalivation and frothing from the mouth. Examination of the three most severely affected Friesian calves revealed severe nicotinic-type symptoms including hypersalivation, frothing from the mouth, muscle tremors, recumbency, rapid respiration, hyperaesthesia, and central nervous system depression. Other calves showed mild to moderate signs of intoxication including restlessness, tail switching, salivation, tremors, frequent defaecation, mild colic and jaw chomping. Two calves died shortly afterwards. An adverse drug event investigation revealed that the formulation and quality of the anthelmintic was within the correct specification, and that the drench gun was functioning correctly. Suspected levamisole intoxication due to a combination of possible overdosing, dehydration, and stress caused by transportation and prolonged yarding. Susceptibility to levamisole toxicity in New Zealand calves can be increased if factors like dehydration or stress are present. Levamisole has a narrow margin of safety, and overdosing in calves can easily occur if the dose rate is not based on their actual weight or health status.

After preliminary examination each patient was advised to put dexamethasone drop 1 % in one eye and a placebo in other eye. The IOP was noted after three weeks It was found that 80% of all eyes under study showed a rise in IOP after use of topical dexamethasone. The highest mean IOP was found in primary open angle glaucoma suspects, and the highest mean post-corticosteroid rise in IOP of 8.91 mm Hg was found among family members of established open angle glaucoma patients. The lOP response to topical corticosteroids was found to be of three phenotypical types viz., poor responders (nn, moderate responders (ng and high responders (gg. Normal subjects were generally poor responders. Suspected open angle glaucoma cases were generally high responders. However, family members of established open angle glaucoma cases showed the highest percentage of presence of responder gene.

    The aim of this study was to evaluate the performance of a commercially available multiplex RT-PCR assay for the rapid detection and identification of dermatophytes directly from clinical samples and cultures. The multiplex RT-PCR assay was used to evaluate 118 clinical isolates from various specimen types and a total of 140 known specimens were compared with both conventional methods, commercially available PCR-REBA, and ITS sequence analysis. In this study, multiplex RT-PCR assay yield significantly more positive results than culture (91·9 vs 39·5%) and conventional methods including KOH microscopy (91·9 vs 71·3%). Although the results among the multiplex RT-PCR, PCR-REBA and ITS sequence analysis were concordant (100%) in 118 clinical isolates, concordant results between multiplex RT-PCR assay and culture were at 66% (78/118). The overall positive rates for the PCR-REBA, multiplex RT-PCR assay and ITS sequence analysis were 98·8, 91·9, and 52·9% respectively. In addition, the concordance rate of multiplex RT-PCR assay and the PCR-REBA assay was 93% (95% confidence interval (CI), 89·9-96·1, P culture can take up to 2-3 weeks. The use of the multiplex RT-PCR molecular diagnostic assay was rapid and reliable for detecting pathogen infections. Even though the use of molecular diagnostic technology is more expensive than conventional methods, the clinical and economic benefit of saving time relative to expense remains to be elucidated. Therefore, the multiplex RT-PCR assay may provide the essential information to accelerate therapeutic decisions for earlier and adequate antibiotic treatment in the acute phase of fungal pathogen infections. © 2015 The Society for Applied Microbiology.

  7. Eclectic Ocular Comorbidities and Systemic Diseases with Eye Involvement: A Review

    Directory of Open Access Journals (Sweden)

    María D. Pinazo-Durán

    2016-01-01

    Full Text Available Coexistence of several ocular diseases is more frequent than suspected. In spite of the refractive errors, one or more of the following can be detected simultaneously: glaucoma, cataracts, uveitis, age-related macular degeneration, and dry eyes. In addition, as people age, ocular comorbidities are much more usually seen. Specific diseases are openly acknowledged to affect the eyes and vision, such as diabetes mellitus, hypertension blood pressure, arthritis, hyperthyroidism, neurodegenerative disorders, hematologic malignancies, and/or systemic infections. Recent advances in early diagnosis and therapy of the ophthalmic pathologies have reinforced patient options to prevent visual impairment and blindness. Because of this, it is essential not to overlook sight-threatening conditions such as the ocular comorbidities and/or the eye involvement in the context of systemic disorders. Moreover, the important role of the multidisciplinary cooperation to improve and sustain management of patients affected with eclectic ocular comorbidities and/or systemic disorders with eye repercussion is specifically addressed. This review intends to shed light on these topics to help in making opportune diagnosis and appropriately managing the affected patients.

    Focal brain lesion is a neurological complication in HIV, which is marked as a space occupying lesion (SOL) and needs rapid and effective treatment. This lesion is mainly caused by encephalitis toxoplasma and primary central nervous system lymphoma related to the Epstein-Barr virus (EBV) infection, which is difficult to distinguish using CT scan or magnetic resonance imaging (MRI). The gold standard of diagnosing focal brain lesion has been brain biopsy, but this examination is an invasive procedure that causes complications. The objective of this study is to obtain the rapid laboratory diagnosis of Toxoplasma gondii (T. gondii) and EBV infection. In this experimental study, blood and cerebrospinal fluid were obtained from HIV patients who were admitted to the Neurology Department of Cipto Mangunkusumo Hospital. The samples were examined using duplex real-time polymerase chain reaction (PCR) to detect T. gondii and EBV. The first step was the optimization of duplex real-time PCR, including the annealing temperature, primer and probe concentration, elution volume, and template volume. Minimal DNA detection was used to measure minimal T. gondii and EBV. Cross reactions were determined for technical specificity using the bacteria and viruses Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa, Mycobacterium tuberculosis H37Rv, Candida spp, cytomegalovirus, herpes zoster virus, and varicella zoster virus. Duplex real-time PCR was applied optimally to patients. In the optimization of duplex real-time PCR, the annealing temperature of T. gondii and EBV were 58 °C, the concentration of primer forward and reverse for T. gondii and EBV were 0.2 μM, the concentration of probe for T. gondii and EBV were 0.4μM and 0.2 μM, respectively. Minimal DNA detection of T. gondii and EBV were 5.68 copy/ml and 1.31 copy/ml, respectively. There was no cross reaction between another bacteria and virus that were used as the primer and probe for T. gondii and EBV. The

    Full Text Available A infecção pelo vírus linfotrópico de células T humanas (HTLV ocorre há milhares de anos. No entanto, o conhecimento sobre a sua patogênese é recente. Esse vírus é endêmico em várias regiões do mundo. No Brasil encontra-se presente em todos os estados, com prevalências variadas, sendo estimado cerca de 2,5 milhões de infectados. Fatores genéticos e imunológicos do hospedeiro são os principais responsáveis pelas manifestações clínicas associadas, que podem ser divididas em três categorias: neoplásicas, inflamatórias e infecciosas. Destacam-se a mielopatia associada ao HTLV (HAM/TSP e a leucemia/linfoma de células T do adulto (ATLL como as primeiras doenças associadas a esse retrovírus. Posteriormente, inúmeras outras doenças têm sido correlacionadas a esse vírus. Esta revisão atualiza conhecimentos epidemiológicos, fisiopatológicos, terapêuticos e principalmente diagnósticos do HTLV. O objetivo é permitir a suspeita etiológica do HTLV em suas diversas manifestações clínicas, hoje pouco correlacionadas com este agente.Human T Lymphotropic Virus (HTLV infection has occurred for thousands of years.

    Full Text Available Pictorial images are icons as well as eye-cons: they provide distillations of objects or ideas into simpler shapes. They create the impression of representing that which cannot be presented. Even at the level of the photograph, the links between icon and object are tenuous. The dimensions of depth and motion are missing from icons, and these alone introduce all manner of potential ambiguities. The history of art can be considered as exploring the missing link between icon and object. Eye-cons can also be illusions—tricks of vision so that what is seen does not necessarily correspond to what is physically presented. Pictorial images can be spatialised or stylised; spatialised images generally share some of the projective characteristics of the object represented. Written words are also icons, but they do not resemble the objects they represent—they are stylised or conventional. Icons as stylised words and spatialised images were set in delightful opposition by René Magritte in a series of pipe paintings, and this theme is here alluded to. Most of visual science is now concerned with icons—two-dimensional displays on computer monitors. Is vision now the science of eye-cons?

    2011-04-01

    In order to analyze the diagnostic efficiency of saccadic and pursuit eye movements compared to findings from brain magnetic resonance imaging in patients with central vertigo, 108 patients were selected from 580 dizzy patients as cases of suspected central origin; the saccadic and pursuit eye movements were evaluated by electronystagmography and findings were compared to information from magnetic resonance imaging. The study of oculomotor movements in patients suspected of having a central lesion revealed a 83.3% sensitivity and 21.2% specificity. Restricting consideration to severe alterations in eye movements as indicative of a central origin, this test gives a 71.4% sensitivity and 50.0% specificity. In conclusion, the study of alterations in oculomotor movements, in patients with suspected central lesions, proved to be a test with good sensitivity also compared with results of magnetic resonance imaging.

    Fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has proven useful in the diagnosis, staging, and detection of metastasis and posttreatment monitoring of several malignancies in human immunodeficiency virus (HIV)-infected patients. It also has the ability to make the important distinction between malignancy and infection in the evaluation of central nervous system (CNS) lesions, leading to the initiation of the appropriate treatment and precluding the need for invasive biopsy. We report an interesting case of HIV positive 35-year-old woman presented with headache, disorientation, and decreased level of consciousness. She underwent whole body PET/CT which showed multiple lesions in the cerebrum which mimics bilateral eye in brain. A diagnosis of a primary CNS lymphoma was made and patient was started on chemotherapy.

    Accurate intraocular pressure (IOP) measurement, important in managing pediatric glaucoma, often presents challenges. The Icare rebound tonometer shows promise for screening healthy children and has been reported comparable with Goldmann applanation in adults with glaucoma. The purpose of this study was to evaluate the Icare tonometer against Goldmann applanation for clinic IOP measurement in pediatric glaucoma. This was a prospective study comparing Icare versus Goldmann tonometry in pediatric glaucoma. Children with known or suspected glaucoma were recruited from scheduled clinic visits. IOP was measured with the Icare tonometer by a clinician and subsequently measured with Goldmann applanation tonometry (GAT) by a different single masked clinician. A total of 71 eyes of 71 children with known or suspected glaucoma were included. IOP by GAT ranged from 9 to 36 mm Hg. Icare readings ranged from 11 to 44 mm Hg. Mean difference between Icare and GAT was 2.3 ± SD 3.7 mm Hg, p IOPs were within ± 3 mm Hg of GAT in 63%. Icare IOPs were ≥GAT IOPs in 75%. The following factors were not associated with Icare IOPs greater than GAT: child's age, glaucoma diagnosis, strabismus, nystagmus, central corneal thickness, Icare instrument-reported reliability, number of glaucoma surgeries or medications, corneal abnormalities, and visual acuity. IOP by Icare tonometry was within 3 mm Hg of IOP by GAT in 63% and greater than GAT in 75%. This device may be reasonable to estimate IOP in selected children with known or suspected glaucoma whose IOP cannot otherwise be obtained in clinic; however, correlation of Icare IOPs with clinical findings must continue to be considered in each case.

    2015-10-01

    Full Text Available AIM:To compare the dynamic changes of anterior segment parameters especially iris morphology induced by pharmacologic mydriasis between angle closure suspects and normal controls.METHODS:The study group comprised 19 eyes of 19 angle closure suspects and 19 eyes of 19 age- and sex-matched normal open-angle eyes. Pentacam and optical coherence tomography measurements before and 30min after instillation of compound tropicamide eye drop were performed and compared. Biometric evaluations of iris tomography and anterior chamber angle were estimated by a customized image-processing software.RESULTS:Baseline axial length, iris cross sectional area and volume did not differ significantly between angle closure suspects and normal controls. Angle closure suspects had smaller pupil size, narrower anterior segment dimension and axial length, thinner iris with greater curve in comparison with normal controls. Pharmacologic mydriasis led to significant increments in iris thickness at 750 μm, anterior chamber depth and volume, whereas significant decrements in iris curve, cross sectional area and volume in both groups. Angle opening distance at 500 μm was increased significantly in normal controls (from 0.465±0.115 mm to 0.539±0.167 mm, P=0.009, but not in angle closure suspects (from 0.125±0.100 mm to 0.145±0.131 mm, P=0.326. Iris volume change per millimeter of pupil dilation (△IV/△PD decreased significantly less in angle closure suspects than normal controls (-2.47±1.33 mm2 vs -3.63±1.58 mm2, P=0.019. Linear regression analysis showed that the change of angle opening distance at 500 μm was associated most with the change of central anterior chamber depth (β=0.841, P=0.002 and △IV/△PD (β=0.028, P=0.002, followed by gender (β=0.062, P=0.032.CONCLUSION:Smaller iris volume decrement per millimeter of pupil dilation is related significantly with the less anterior angle opening in angle closure suspects after pharmacologic mydriasis.

    2011-06-01

    Brucellosis is a zoonotic disease which can be transmitted by direct or indirect contact with infected animal or their products. It is an important public health problem but little is known on brucellosis in the Malaysian population. The aim of this study was to determine the presence of Brucella antibodies using commercial Brucella IgG and IgM ELISA kits (Vircell, SL, Barcelona Spain). A total of 184 sera from suspected patients were received from 16 hospitals in Malaysia over the years 2004 to 2009. Only 10 serum samples (5.4%) were positive for Brucella antibodies in which 5 showed the presence of both IgM and IgG. Most of the positive patients were occupationally involved with animals. This study suggests the seroprevalance of brucellosis among individuals who have contact with infected animals in Malaysia is low.

  11. The phenomenology of specialization of criminal suspects.

    Directory of Open Access Journals (Sweden)

    Michele Tumminello

    Full Text Available A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commit crimes of certain types, and, for instance, are more prone to specialize in crimes related to fraud. We also find evidence of temporal specialization of suspects. Older persons are more specialized than younger ones, and some crime types are preferentially committed by suspects of different ages.

    Full Text Available Purpose: To explore retinal ganglion cell (RGC dysfunction in glaucoma suspects and patients with early primary open angle glaucoma (POAG using pattern electroretinography (PERG. Methods: Twenty glaucoma suspects (glaucomatous optic disc appearance, 15 early POAG (based on abnormal discs and abnormal visual fields and 16 normal controls were enrolled. Transient PERG was recorded in response to 0.8΀ and 16΀ black and white checkerboard stimuli. Amplitude and peak time (latency of the P50 and N95 components of the PERG response, and the ratio of N95 amplitude in response to 0.8΀ and 16΀ checks were measured. Results: N95 peak time (latency was significantly increased in both early manifest POAG and glaucoma suspects as compared to normal controls (P<0.001. In early POAG, N95 amplitude in response to small (0.8΀ checks and the small/large check ratio were reduced in comparison to normal eyes (P<0.05. However, in glaucoma suspects no significant N95 amplitude reduction was observed. No significant difference was observed among the study groups in terms of P50 amplitude or peak time. Conclusion: The N95 PERG response demonstrated uncoupled peak time and amplitude alterations in glaucoma. N95 peak time was significantly increased both in glaucoma suspects and early POAG; N95 amplitude reduction was present only in early POAG. PERG may detect RGC dysfunction (increased latency before cell death (decreased amplitude occurs.

    2013-01-01

    Dry eye is a common ocular surface disease of multifactorial etiology characterized by elevated tear osmolality and inflammation leading to a disrupted ocular surface. The latter is a risk factor for ocular surface infection, yet overt infection is not commonly seen clinically in the typical dry eye patient. This suggests that important innate mechanisms operate to protect the dry eye from invading pathogens. This article reviews the current literature on epidemiology of ocular surface infection in dry eye patients and laboratory-based studies on innate immune mechanisms operating at the ocular surface and their alterations in human dry eye and animal models. The review highlights current understanding of innate immunity in dry eye and identifies gaps in our knowledge to help direct future studies to further unravel the complexities of dry eye disease and its sequelae.

    An important group of suspected illegal cosmetics consists of skin bleaching products, which are usually applied to the skin of the face, hands and décolleté for local depigmentation of hyper pigmented regions or more importantly, for a generalized reduction of the skin tone. These cosmetic products are suspected to contain illegal active substances that may provoke as well local as systemic toxic effects, being the reason for their banning from the EU market. In that respect, illegal and restricted substances in cosmetics, known to have bleaching properties, are in particular hydroquinone, tretinoin and corticosteroids. From a legislative point of view, all cosmetic products containing a prohibited whitening agent are illegal and must be taken off the EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin whitening cosmetics, collected by Belgian inspectors at high risk sites such as airports and so-called ethnic cosmetic shops, were analyzed and 59% were classified as illegal. The whitening agents mostly detected were clobetasol propionate and hydroquinone, which represent a serious health risk when repeatedly and abundantly applied to the skin.

    To review all cases of suspected vitreous seeding of treated or untreated uveal melanoma at our clinic and to compare clinical, cytological and histological findings with patients' survival. Retrospective non-randomised study of 23 patients with consecutive uveal melanoma who underwent diagnostic vitrectomy in our clinic between January 2000 and November 2013. Reason for vitrectomy was suspected dissemination of tumour cells inside the eye. Treated as well as treatment-naïve primary uveal melanomas were included in this study. Follow-up data of all patients were collected. The study included 23 patients with a mean age of 66 years. Four patients presented pigmented vitreous debris at initial presentation prior to treatment of the uveal melanoma. All but one of these four patients has been enucleated as a consequence of cytology-proven vitreous spreading of vital melanoma cells. The remaining 19 patients presented pigmented vitreous debris at a mean of 60 months following local tumour treatment. Thirteen of these patients had been treated with a ruthenium plaque (mean scleral dose 1295 Gy, mean apex dose 152 Gy), three with binuclid plaque (mean scleral dose 1005 Gy, mean apex dose 70 Gy) and three with proton beam radiation. Of the 19 patients, 10 showed only melanophages in the vitreous specimen, while the remaining 9 patients had vital tumour cells in vitreous cytology. Four out of these nine patients have been enucleated in the course of follow-up. During follow-up of our cohort of 23 patients, 4 patients died, but only 1 of them due to metastatic disease. The outcome of this small cohort study shows that obtaining a vitreous specimen helps to distinguish melanophages from vital tumour cells. We could not observe an increased risk of metastasis in patients who showed melanoma cell dissemination inside the eye, compared with those patients only showing melanophages. We therefore suggest to carefully re-evaluate the necessity of enucleation in every

    2016-01-01

    A retrospective study was carried out by reviewing all suspected cases of domestic animal poisoning attributed to pesticides, reported to the Milan Poison Control Centre (MPCC) between January 2011 and December 2013. During this period, pesticides were found to be responsible for 37.3% of all suspected poisoning enquiries received (815). The most commonly species involved was the dog (71.1% of calls) followed by the cat (15.8%), while a limited number of cases involved horses, goats and sheep. Most cases of exposure (47.1%) resulted in mild to moderate clinical signs. The outcome was reported in 59.9% of these cases, with death occurring in 10.4% of them. Insecticides (40.8%) proved to be the most common group of pesticides involved and exposure to pyrethrins-pyrethroids accounted for the majority of calls. According to the MPCC data, there has been a decrease in the number of suspected poisonings cases attributed to pesticides that have been banned by the EU, including aldicarb, carbofuran, endosulfan and paraquat. In contrast, there has been an increase of suspected poisoning cases attributed to the neonicotinoids, imidacloprid and acetamiprid, probably due to their widespread use in recent years. Cases of suspected poisoning that involved exposure to rodenticides accounted for 27.6% of calls received by the MPCC and anticoagulant rodenticides were the primary cause of calls, with many cases involving brodifacoum and bromadiolone. Herbicides were involved in 14.2% of calls related to pesticides and glyphosate was the main culprit in cases involving dogs, cats, horses, goats and sheep. As far as exposure to molluscicides (11.5%) and fungicides (5.9%), most of the cases involved dogs and the suspected poisoning agents were metaldehyde and copper compounds respectively. The data collected are useful in determining trends in poisoning episodes and identifying newly emerging toxicants, thus demonstrating the prevalence of pesticides as causative agents in animal

    Child physical abuse is an important cause of pediatric morbidity and mortality and is associated with major physical and mental health problems that can extend into adulthood. Pediatricians are in a unique position to identify and prevent child abuse, and this clinical report provides guidance to the practitioner regarding indicators and evaluation of suspected physical abuse of children. The role of the physician may include identifying abused children with suspicious injuries who present for care, reporting suspected abuse to the child protection agency for investigation, supporting families who are affected by child abuse, coordinating with other professionals and community agencies to provide immediate and long-term treatment to victimized children, providing court testimony when necessary, providing preventive care and anticipatory guidance in the office, and advocating for policies and programs that support families and protect vulnerable children.

  11. Suspects in criminal investigations of rape

    Directory of Open Access Journals (Sweden)

    Marinković Darko

    2014-01-01

    Full Text Available Investigations of sexual assaults mostly focus on victims and their credibility, which may cause lack of firm evidence in relation to suspects. Given the fact that the criminal offence of rape is characterised by a high incidence of false reports and accusations, frequently indicating specific persons as the perpetrators, certain caution is necessary in the investigation in order to avoid false accusations and/or convictions. As regards the personality of the rapist and motives for committing a forcible sexual act, certain types or rather certain categories of perpetrators can be distinguished, although it should be noted that a large number of rapists do not belong to one category only, but rather combine characteristics of several different types. During a criminal investigation it is of vital importance to differentiate between a rape as a surprise attack and a rape as abuse of trust, as they are compatible with the nature of the suspect's defence. The suspect shall be subjected to a forensic examination in the course of the investigation in order to find traces which prove vaginal, anal or oral penetration, coerced sexual intercourse and identity of the rapist. While conducting an interrogation of a suspected rapist, a crime investigating officer shall use either factual or emotional approach to his interviewee, depending on his psychological and motivational characteristics. In this regard, the factual approach is believed to be more efficient with anger rapists and sadistic rapists, whereas the compassionate approach gives good results with the gentlemen-rapists and partly with the power asserting rapists.

  12. Tocolytics for suspected intrapartum fetal distress.

    Kulier, R; Hofmeyr, G J

    2000-01-01

    Prophylactic tocolysis with betamimetics and other agents has become widespread as a treatment for fetal distress. Uterine relaxation may improve placental blood flow and therefore fetal oxygenation. However there may also be adverse maternal cardiovascular effects. The objective of this review was to assess the effects of tocolytic therapy for suspected fetal distress on fetal, maternal and perinatal outcomes. We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register. Date of last search: February 1999. Randomised trials comparing tocolytic therapy with no treatment or treatment with another tocolytic agent for suspected fetal distress. Two reviewers assessed trial quality and extracted data. Three studies were included. Compared with no treatment, there were fewer failed improvements in fetal heart rate abnormalities with tocolytic therapy (relative risk 0.26, 95% 0.13 to 0.53). Betamimetic therapy compared with magnesium sulphate showed a non-significant trend towards reduced uterine activity (relative risk 0.07, 95% confidence interval 0.00 to 1.10). Betamimetic therapy appears to be able to reduce the number of fetal heart rate abnormalities and perhaps reduce uterine activity. However there is not enough evidence based on clinically important outcomes to evaluate the use of betamimetics for suspected fetal distress.

    To compare the clinical features of highly myopic eyes with a dome-shaped macula (DSM) with those without a DSM and to identify the funduscopic clues to suspect the presence of DSM. Retrospective case series. A total of 586 patients (1118 eyes) with high myopia (refractive error 50 μm in the vertical OCT image. Fundus photographs also were analyzed to identify the funduscopic clues to suspect the presence of DSM. The rate of DSM in 1118 highly myopic eyes. The rate of DSM in highly myopic eyes with macular complications. Funduscopic features to suggest the presence of DSM. Among the 1118 eyes, 225 (20.1%) had a DSM. A DSM was present in both vertical and horizontal OCT sections in 20% of eyes, along only the vertical section in 77% of eyes, and in only the horizontal section in 2% of eyes. The results of multiple regression analyses showed that serous retinal detachment and foveal and extrafoveal retinoschisis were significantly associated with the presence of DSM and that choroidal neovascularization was not. Ophthalmoscopically, 91.4% of the eyes with the appearance of a horizontal ridge connecting the optic disc and the fovea had a DSM. A DSM is found in as many as 20% of highly myopic individuals. Horizontal ridges connecting the optic disc and the fovea might be an important clue to suspect the presence of a DSM on the basis of fundus photographs.

    Surgical site infections (SSIs) and especially organ/space infection (O/SI) after resection or ablation of liver tumors are associated with increased morbidity and mortality. A secondary blood stream infection (BSI) is considered an O/SI but the exact prevalence is unknown. We aimed to investigate the incidence of O/SI and BSIs in a cohort of consecutive patients after liver resection or ablation, to seek for a possible connection between them and to search for potential risk factors. We reviewed all patients who underwent hepatic resection or intraoperative liver ablation between January 2012 and December 2016 in our department. We focused on age, gender, Child-Pugh score, preoperative biliary drainage, indication for surgery, type of resection, resection or ablation of tumor, need for bilioenteric reconstruction, additional procedure to hepatectomy, blood transfusion, operative time, postoperative admission to ICU, and antibiotic chemoprophylaxis. All positive cultures from intra-abdominal fluids and blood were recorded. O/SI and BSIs were diagnosed by the criteria set by Centers for Disease Control. All variables were compared between the group with O/SI and the group without infection. BSIs were associated with these infections also. Eighty-one consecutive patients with a mean age of 64 years were enrolled. Fifteen patients presented a positive culture postoperatively: intra-abdominal fluid in eight, blood cultures in six, and both blood and intra-abdominal fluid in one patient. The directly estimated incidence of O/SI amounted to 11.1%. Four blood cultures were secondary to O/SI, and the remaining two secondary to central line catheter. O/SI was diagnosed indirectly, through the BSI in an additional 4.9% of the patients, raising the incidence of SSI to 16%. Among the factors studied, only admission to the ICU was found to be statistically significant as a risk factor for the development of O/SI (p = 0.026). O/SI should be actively seeked for after liver

    Full Text Available Abstract The criteria for the diagnosis of HNPCC established by the ICG-HNPCC are very restrictive as they do not allow for the diagnosis of a large number of "suspected HNPCC" cases - these are families which do no fulfill the strict diagnostic "Amsterdam criteria", but do present with several pedigree and clinical features characteristic for HNPCC. Several series of families suspected of harboring germline mutations in DNA mismatch repair genes have been studied for germline changes in DNA mismatch repair genes and a mutation rate of somewhere between 8-60% was found. Therefore a subgroup of members of the ICG-HNPCC has been working on pedigree/clinical diagnostic criteria for suspected HNPCC. Materials and methods Part I The study was based on two series of colorectal cancer (CRC cases: 1 HNPCC - this group comprised 190 patients affected by CRC from randomly selected families which fulfilled the Amsterdam II criteria registered in Düsseldorf, Germany (102 cases of CRC, Denmark (18 CRCs, Leiden, Holland (23 CRCs and Szczecin, Poland (47 CRCs. 2 Consecutive CRCs - this group comprised 629 (78.0% of 806 individuals with CRC diagnosed in 1991-1997 in the city of Szczecin (ca. 400,000 of inhabitants, Poland. Nuclear pedigrees in both groups were compared for frequency of occurrence of clinical features, that have been shown to be associated with HNPCC. Part II 52 consecutive CRC cases from Szczecin, matching the criteria recognized in part I as appropriate for diagnosis of cases "suspected of HNPCC" were studied for the occurrence of germline hMSH2/hMLH1 constitutional mutations using "exon by exon" sequencing. Results The combination of features - i.e. the occurrence of an HNPCC associated cancer (CRC or cancer of the endometrium, small bowel or urinary tract in a 1st degree relative of a CRC patient; at least one of the patients being diagnosed under age of 50 - appeared to be strongly associated to HNPCC with an OR - 161.

    Full Text Available Research from evolutionary psychology suggests that the mere presence of eye images can promote prosocial behavior. However, the “eye images effect” is a source of considerable debate, and findings across studies have yielded somewhat inconsistent support. We suggest that one critical factor may be whether the eyes really need to be watching to effectively enhance prosocial behavior. In three experiments, we investigated the impact of eye images on prosocial behavior, assessed in a laboratory setting. Participants were randomly assigned to view an image of watching eyes (eyes with direct gaze, an image of nonwatching eyes (i.e., eyes closed for Study 1 and averted eyes for Studies 2 and 3, or an image of flowers (control condition. Upon exposure to the stimuli, participants decided whether or not to help another participant by completing a dull cognitive task. Three independent studies produced somewhat mixed results. However, combined analysis of all three studies, with a total of 612 participants, showed that the watching component of the eyes is important for decision-making in this context. Images of watching eyes led to significantly greater inclination to offer help as compared to images of nonwatching eyes (i.e., eyes closed and averted eyes or images of flowers. These findings suggest that eyes gazing at an individual, rather than any proxy to social presence (e.g., just the eyes, serve as a reminder of reputation. Taken together, we conclude that it is “eyes that pay attention” that can lift the veil of anonymity and potentially facilitate prosocial behavior.

    To study whether plasma viral load testing is helpful to exclude ones free from Human immunodeficiency virus (HIV) infections from suspects in HIV antibody detections. 19 Specimens, which showed disconcordant results of the two HIV EIA testing (S/CO test, were selected. Viral load of the specimens were detected. A six-month follow up survey in detecting HIV antibody was conducted in these subjects. None of these 19 cases was observed to be positive HIV viral loads and there was no any progress in WB bands development during the follow-up period. The possibility of HIV infection could be excluded. When the specimens react with very low intensity in both EIA and WB, negative viral load result is conducive to exclude negative subjects from suspects in HIV antibody detections.

    2014-06-01

    Abstract: A female American kestrel (Falco spaverius) fledgling was found on the ground with a suspected trauma to the right eye and open-mouth breathing. During the first 2 days of hospitalization, the bird developed severe bilateral periorbital cellulitis, blepharoedema, and sinusitis. The periocular tissues of the right globe were devitalized and communicated with a fistula at the commissure of the right side of the beak. The blepharoedema of the left eye was aspirated and yielded a dark colored malodorous fluid, which was submitted for aerobic bacterial and Mycoplasma cultures. Results showed a mixed infection with Mycoplasma buteonis, Avibacterium gallinarum, and Staphylococcus pasteuri, all of which are not commonly isolated from birds of prey. With antimicrobial therapy, supportive care, and surgical debridement of the right periocular necrotic tissues and adhesed phthisical globe, the kestrel recovered from this severe mixed upper respiratory infection.

    We herein report a case of suspected Borrelia miyamotoi disease in Hokkaido, Japan. The patient complained of lassitude, arthralgia, and high fever after a tick bite. Furthermore, at the time of consultation, the patient exhibited momentary loss of consciousness and low blood pressure. Laboratory tests revealed elevation of liver enzymes, thrombocytopenia, and increased C-reactive protein. Seroconversion to B. miyamotoi glycerophosphoryl diester phosphodiesterase antigen suggested the patient was infected with a relapsing fever group Borrelia species.

    To assess the diagnostic accuracy of the Edinburgh Red Eye Algorithm. This was a prospective study. A questionnaire was designed and made available to clinicians referring patients to the acute ophthalmology service within Edinburgh. The questionnaire involved them using the algorithm to reach a diagnosis in patients presenting with red eye(s). Patients were then referred to the emergency eye clinic and the questionnaire faxed to the clinic or sent with the patients. Patients were then examined by an experienced ophthalmologist (not blinded) to reach a 'gold standard' diagnosis. The concordance between the 'algorithm assisted' diagnosis and the 'gold standard' was then assessed. All patients presenting with red eye(s) were eligible for inclusion. Forty-one questionnaires were completed, two were excluded. The algorithm assisted diagnosis was correct 72% (28/39) of the time. It correctly diagnosed: acute angle closure glaucoma in 100% of cases (4/4); iritis in 82% (9/11); stromal keratitis in 63% (5/8); epithelial keratitis in 70% (7/10); and infective conjunctivitis in 50% (3/6). The diagnostic accuracy of The Edinburgh Red Eye Diagnostic Algorithm is 72, rising to 76% when only the most serious red eye(s) causes are included. The diagnostic accuracy of non-ophthalmologists when assessing patients presenting with red eye(s) is greater when the algorithm is used. We hope that the use of this algorithm will prevent delayed presentations of certain serious eye conditions and reduce the morbidity from delayed treatment.

    2018-01-01

    To describe our institution's low rate of positive bronchoscopy in infants suspected of inhaling a foreign body. Retrospective chart review. A retrospective review was performed of patients at a tertiary children's hospital with suspected inhalation of a foreign body. Charts were reviewed for demographic information, radiologic findings, operative reports, and respiratory viral panels were reviewed. Sixteen pediatric patients under 12 months of age were identified from 2008 to 2016 with a diagnosis of possible airway foreign body inhalation who underwent emergent bronchoscopy. Of these patients, only one was positive for a foreign body present in the airway. The remaining 15 children were found to have a negative direct laryngoscopy and bronchoscopy evaluation for a foreign body. Of these fifteen patients, 14 were found to have structural airway abnormalities and 7 tested positive for a respiratory viral infection. Our institution has a low rate of positive bronchoscopy for highly suspected foreign body inhalation in a group of patients less than 12 months of age. Patients presenting with respiratory distress, stridor, or other airway symptoms were often found to have an underlying airway abnormality or viral infection, which coupled with an unclear history, would increase the suspicion for an airway foreign body and subsequent decision to perform bronchoscopy. In stable patients, diagnostic evaluation for an underlying respiratory infection should be performed in these cases. Case Series. Copyright © 2017. Published by Elsevier B.V.

    2015-06-01

    Full Text Available Superficial mycoses are estimated to affect more than 20-25% of the world’s population with a consistent increase over the years. Most patients referred to our clinic for suspected dermatomycoses have already been treated with pharmacotherapy, without a previous mycological examination and many show changes in the clinical manifestations. Indeed, some medications, such as steroids, antiviral, antibiotics and antihistamines are not able to erase a fungal infection, but also they can cause atypical clinical manifestations. The consequences of inappropriate treatment include delayed diagnosis, prolonged healing time, and additional costs. The aims of this study were (1 to evaluate the incidence of increased costs attributable to inappropriate therapy sustained by the National Health Service and patients and (2 to highlight the importance of mycological evaluation before starting treatment, in order to improve diagnostic accuracy. An observational retrospective and prospective study was performed from September 2013 to February 2014, in 765 patients referred to our center (University Hospital “ Federico II” in Naples, Italy, for suspected mycological infection. The following treatments (alone or in combination were defined as inappropriate: (1 cortisone in a patient with at least one positive site; (2 antifungals in (a patients with all negative sites or (b ineffective antifungal treatment (in terms of drug chosen, dose or duration in those with all positive sites; or (3 antibiotics; (4 antivirals or (5 antihistamines, in patients with ≥ 1 positive site. Five hundred and fifty patients were using medications before the assessment visit. The total amount of avoidable costs related to inappropriate previous treatments was € 121,417, representing 74% of the total treatment costs. 253/550 patients received drugs also after the visit. For these patients, the cost of treatment prescribed after mycological testing was € 42,952, with a decrease

    In this work the possible influences of some retinal eye problems on paintings of several famous artists are considered. The change of painting styles and artistic expression in different periods and ages in a group of world-wide well-known painters are described and correlated with known or suspected retinal diseases. Some of them largely became recognizable because of that. Contemplations are offered about the effects of retinal diseases in the works of Degas, Munch, Cézanne, O'Keeffe, Constable and Goya. Retinal eye diseases have a significant impact on the work of selected famous painters.

    The contribution of interferon-gamma release assays (IGRAs) to appropriate risk stratification of active tuberculosis suspects has not been studied. To determine whether the addition of quantitative IGRA results to a prediction model incorporating clinical criteria improves risk stratification of smear-negative-tuberculosis suspects. Clinical data from tuberculosis suspects evaluated by the San Francisco Department of Public Health Tuberculosis Control Clinic from March 2005 to February 2008 were reviewed. We excluded tuberculosis suspects who were acid fast-bacilli smear-positive, HIV-infected, or under 10 years of age. We developed a clinical prediction model for culture-positive disease and examined the benefit of adding quantitative interferon (IFN)-gamma results measured by QuantiFERON-TB Gold (Cellestis, Carnegie, Australia). Of 660 patients meeting eligibility criteria, 65 (10%) had culture-proven tuberculosis. The odds of active tuberculosis increased by 7% (95% confidence interval [CI], 3-11%) for each doubling of IFN-gamma level. The addition of quantitative IFN-gamma results to objective clinical data significantly improved model performance (c-statistic 0.71 vs. 0.78; P added clinical value to a prediction model incorporating conventional risk factors. Although this benefit may be attenuated within highly experienced centers, the predictive accuracy of quantitative IFN-gamma levels should be evaluated in other settings.

    To determine the severity and long term sequelae of eye injuries caused by modern sports that could be responsible for significant ocular trauma in the future. Prospective observational study of 24 (25 eyes) athletes with sports related ocular injuries from health clubs, war games, adventure, radical and new types of soccer, presenting to an eye emergency department between 1992 and 2002 (10 years). Modern sports were responsible for 8.3% of the 288 total sports eye injuries reported. Squash (29.2%) was the most common cause, followed by paintball (20.8%) and motocross (16.6%). The most common diagnosis during the follow up period was retinal breaks (20%). 18 (75%) patients sustained a severe injury. The final visual acuity remained paintball players. Ocular injuries resulting from modern sports are often severe. Adequate instruction of the participants in the games, proper use of eye protectors, and a routine complete ophthalmological examination after an eye trauma should be mandatory.

  1. Sporotrichosis in Iran: A mini review of reported cases in patients suspected to cutaneous leishmaniasis

    Directory of Open Access Journals (Sweden)

    shahram mahmoudi

    2015-03-01

    Full Text Available Sporotrichosis is a chronic subcutaneous fungal infection with global distribution. It is a rare fungal infection with nine reported cases in Iran, including eight humans and one animal, within the past 30 years. Among the human cases, seven were of the fixed cutaneous type of sporotrichosis and one had sporotrichoid lymphocutaneous. The reported patients were within the age range of 23-60 years, and six of them were female. The most frequent sites of infection were forearms and hands, as well as the face and legs. In addition, the majority of the cases had previously been suspected of leishmaniasis and received treatment. Sporotrichosis is not a well-known condition in Iran and is often misdiagnosed and erroneously treated for other cutaneous parasitic or bacterial infections with similar clinical manifestations. Therefore, sporotrichosis should be taken into account in the differential diagnosis of nodular-ulcerative skin lesions.

    1992-05-01

    Two-dimensional echocardiography has become the standard technique for evaluation of cardiac and paracardiac mass lesions. We have used magnetic resonance imaging (MRI) as an independent assessment of cardiac-associated masses in patients with echocardiograms demonstrating sessile atrial tumors. MRI was performed in seven patients, ages 33 to 84, whose echocardiographic diagnoses included left atrial mass (five), right atrial mass (one), and interatrial mass (one). In four of the patients with a diagnosis of left atrial mass, MRI showed extracardiac compression of the atrium, simulating a tumor (hiatal hernia, tortuous descending aorta, bronchogenic cyst). MRI was entirely normal in one patient with an apparent left atrial mass. MRI elucidated extension of an extracavitary mass into the interatrial septum in two patients. One of these patients with an echocardiographic right atrial mass had extension of a lipoma into the interatrial septum without atrial tumor. MRI confirmed the echocardiographic diagnosis of an interatrial mass in the other patient. We conclude that MRI, because of its ability to define anatomic relationships and tissue characteristics, is a powerful noninvasive tool for evaluating suspected cardiac mass lesions. Although echocardiography remains the primary screening test for the detection of cardiac masses, MRI is a more specific modality for precise diagnosis. Correct MRI interpretation may obviate the need for invasive studies or surgery.

  9. Facing the Danger Zone: The Use of Ultrasound to Distinguish Cellulitis from Abscess in Facial Infections

    Directory of Open Access Journals (Sweden)

    Dywanda L. Lewis

    2014-01-01

    Full Text Available Physical exam alone is often insufficient to determine whether or not cellulitis is accompanied by an abscess. Bedside ultrasound can be a valuable tool in ruling out suspected abscess by allowing direct visualization of a fluid collection. The proximity of the infection to adjacent structures can also be determined, thus aiding clinical decision making. Patients with cellulitis near the eye and nose are of particular concern due to the adjacent facial structures and the anatomy of the venous drainage. Accurately determining the presence or absence of an associated abscess in these patients is a crucial step in treatment planning. The purpose of this report is to (1 emphasize the benefits of bedside ultrasound when used in conjunction with the physical exam to rule out abscess; (2 demonstrate the utility of bedside ultrasound in planning a treatment strategy for soft tissue infection; (3 depict an instance where ultrasound detected an abscess when computed tomography (CT scan did not.

    2016-09-01

    There is a paucity of data concerning the benefit of bronchoalveolar lavage (BAL) for the diagnosis of suspected peripheral lung cancer (PLC). The aim of this study was to investigate the diagnostic value of BAL for the diagnosis of suspected PLC. All flexible bronchoscopies that included BAL among other modalities (brush, forceps, washing) for the diagnosis of a suspected PLC performed between 2009 and 2013 were analyzed in this retrospective study. A total of 260 patients were included. Malignancy was present in 61%. BAL's sensitivity for the diagnosis of malignancy was 29%, and overall diagnostic yield of BAL was 46%. However, only 1% of cancer diagnoses would have been missed in the absence of BAL. In the multivariable analysis, the size of lesion (odds ratio [OR], 1.17; 95% confidence interval [CI], 1.02-1.33; P = .023), the presence of bronchus sign (OR, 4.73; 95% CI, 1.06-21.08; P = .042), and the presence of mediastinal/hilar lymphadenopathy (OR, 3.37; 95% CI, 1.53-7.41; P = .002) were associated with improved BAL true-positive ratio relating to diagnosis of malignancy. However, the effect of lesion size on sensitivity was small (area under the curve, 0.31; 95% CI, 0.23-0.40; P diagnosis of malignancy or pulmonary infection was 37. Conventional BAL has a low diagnostic value for the diagnosis of suspected PLC, and the low number needed to test does not qualify BAL as a recommended routine investigation for the diagnosis of suspected PLC for either solid or ground-glass lesions.

    Body iron levels have recently been shown to be a strong predictor for non-alcoholic fatty liver disease (NAFLD). The aims of this study were to investigate the prevalence of NAFLD in a general adult population, and to investigate the relationship between body iron levels, NAFLD and the metabolic syndrome (MetS). 2186 adults participated in the third National Nutrition and Health Survey in Taiwan (NAHSIT, 2005-2008). The participants underwent anthropometry measurements and phlebotomy after an overnight fast, and those with excessive alcohol intake, iron overload of serum ferritin > 600 ng/ml, hepatitis viral infection and hepatocellular carcinoma were excluded. Suspected NAFLD was diagnosed by three alanine transaminase (ALT) cut-points: cut-point 1: serum ALT > 40 U/l; cut-point 2: ALT ≥ 25 U/l for male and ALT ≥ 17 U/l for female; and cut-point 3: ALT ≥ 35 U/l for male and ALT ≥ 26 U/l for female. The prevalence proportion of suspected NAFLD among Taiwanese adults was 6.6% (cut-point 1), 36% (cut-point 2); and 14.3% (cut-point 3). Body iron levels were significantly higher in individuals with suspected NAFLD compared with those without. Distribution of hemoglobin levels, but not serum ferritin levels, by decade of age showed strong correlation with the prevalence of suspected NAFLD in individuals with MetS. Multivariate adjusted odds ratio (OR) showed that the best predictors for suspected NAFLD with the MetS were hemoglobin [OR 1.43 (1.21-1.68); P hemoglobin [OR 1.25 (1.12-1.41); P hemoglobin levels (14.4 μg/dl for male and 13.2 μg/dl for female) are at the greatest risk for developing abnormal liver function. Hemoglobin test should be considered as a part of clinical evaluation for patients with NAFLD.

    2010-09-01

    Full Text Available Abstract Background Numerous studies have shown that Epstein-Barr virus (EBV and cytomegalovirus (CMV can infect immunocompetent patients simultaneously with other agents. Nonetheless, multiple infections with other agents in EBV/CMV-infected children have received little attention. We conducted a retrospective study of children with suspected infectious mononucleosis. Peripheral blood samples were analyzed by indirect immunofluorescence to detect EBV, CMV and other respiratory agents including respiratory syncytial virus; adenovirus; influenza virus types A and B; parainfluenza virus types 1, 2 and 3; Chlamydia pneumoniae and Mycoplasma pneumoniae. A medical history was collected for each child. Results The occurrence of multipathogen infections was 68.9%, 81.3% and 63.6% in the children with primary EBV, CMV or EBV/CMV, respectively, which was significantly higher than that in the past-infected group or the uninfected group (p C. pneumoniae in children with primary infection was as high as 50%, significantly higher than in the other groups (p Conclusion Our study suggests that there is a high incidence of multipathogen infections in children admitted with EBV/CMV primary infection and that the distribution of these pathogens is not random.

    Meningococcal disease can lead to death or disability within hours after onset. Pre-admission antibiotics aim to reduce the risk of serious disease and death by preventing delays in starting therapy before confirmation of the diagnosis. To study the effectiveness and safety of pre-admission antibiotics versus no pre-admission antibiotics or placebo, and different pre-admission antibiotic regimens in decreasing mortality, clinical failure and morbidity in people suspected of meningococcal disease. We updated searches of CENTRAL (2013, Issue 4), MEDLINE (1966 to April week 4, 2013), EMBASE (1980 to May 2013), Web of Science (1985 to May 2013), CAB Abstracts (1985 to May 2013), LILACS (1982 to May 2013) and prospective trials registries to May 2013. Randomised controlled trials (RCTs) or quasi-RCTs comparing antibiotics versus placebo or no intervention, in people with suspected meningococcal infection, or different antibiotics administered before admission to hospital or confirmation of the diagnosis. Two review authors independently assessed trial quality and extracted data from the search results. We calculated the risk ratio (RR) and 95% confidence interval (CI) for dichotomous data. We included only one trial so data synthesis was not performed. We assessed the overall quality of the evidence using the GRADE approach. We found no RCTs that compared pre-admission antibiotics versus no pre-admission antibiotics or placebo. One open-label, non-inferiority RCT, conducted during an epidemic in Niger, evaluated a single dose of intramuscular ceftriaxone versus a single dose of intramuscular long-acting (oily) chloramphenicol. Ceftriaxone was not inferior to chloramphenicol in reducing mortality (RR 1.2, 95% CI 0.6 to 2.6; N = 503; 308 confirmed meningococcal meningitis; 26 deaths; moderate-quality evidence), clinical failures (RR 0.8, 95% CI 0.3 to 2.2; N = 477, 18 clinical failures; moderate-quality evidence) or neurological sequelae (RR 1.3, 95% CI 0.6 to 2.6; N

    Fever, which is closely linked to viraemia, is considered to be both the main and the earliest clinical sign in sheep infected with bluetongue virus (BTV). The aim of this study was to evaluate the potential use of infrared thermography (IRT) for early detection of fever in sheep experimentally infected with bluetongue virus serotype 1 (BTV-1) and serotype 8 (BTV-8). This would reduce animal stress during experimental assays and assist in the development of a screening method for the identification of fever in animals suspected of being infected with BTV. Rectal and infrared eye temperatures were collected before and after BTV inoculation. The two temperature measures were positively correlated (r=0.504, P<0.05). The highest correlation between rectal and infrared temperatures was observed when temperatures were above physiological levels. IRT discriminated between febrile and non-febrile sheep with a sensitivity of 85% and specificity of 97%. The results showed that eye temperature measured using IRT was a useful non-invasive method for the assessment of fever in sheep infected with BTV under experimental conditions. Further research is required to evaluate the use of IRT under field conditions to identify potentially infected animals in bluetongue surveillance programmes. Copyright © 2013 Elsevier Ltd.

  16. Advocacy for eye care

    Directory of Open Access Journals (Sweden)

    Thulasiraj D Ravilla

    2012-01-01

    Full Text Available The effectiveness of eye care service delivery is often dependant on how the different stakeholders are aligned. These stakeholders range from the ministries of health who have the capacity to grant government subsidies for eye care, down to the primary healthcare workers who can be enrolled to screen for basic eye diseases. Advocacy is a tool that can help service providers draw the attention of key stakeholders to a particular area of concern. By enlisting the support, endorsement and participation of a wider circle of players, advocacy can help to improve the penetration and effectiveness of the services provided. There are several factors in the external environmental that influence the eye care services - such as the availability of trained manpower, supply of eye care consumables, government rules and regulations. There are several instances where successful advocacy has helped to create an enabling environment for eye care service delivery. Providing eye care services in developing countries requires the support - either for direct patient care or for support services such as producing trained manpower or for research and dissemination. Such support, in the form of financial or other resources, can be garnered through advocacy.

  18. Prediction of Suspect Location Based on Spatiotemporal Semantics

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The prediction of suspect location enables proactive experiences for crime investigations and offers essential intelligence for crime prevention. However, existing studies have failed to capture the complex social location transition patterns of suspects and lack the capacity to address the issue of data sparsity. This paper proposes a novel location prediction model called CMoB (Crime Multi-order Bayes model based on the spatiotemporal semantics to enhance the prediction performance. In particular, the model groups suspects with similar spatiotemporal semantics as one target suspect. Then, their mobility data are applied to estimate Markov transition probabilities of unobserved locations based on a KDE (kernel density estimating smoothing method. Finally, by integrating the total transition probabilities, which are derived from the multi-order property of the Markov transition matrix, into a Bayesian-based formula, it is able to realize multi-step location prediction for the individual suspect. Experiments with the mobility dataset covering 210 suspects and their 18,754 location records from January to June 2012 in Wuhan City show that the proposed CMoB model significantly outperforms state-of-the-art algorithms for suspect location prediction in the context of data sparsity.

  19. Optic Disc Change during Childhood Myopic Shift: Comparison between Eyes with an Enlarged Cup-To-Disc Ratio and Childhood Glaucoma Compared to Normal Myopic Eyes.

    Directory of Open Access Journals (Sweden)

    Hae-Young Lopilly Park

    Full Text Available Progressive disc tilting and the development or enlargement of peripapillary atrophy (PPA are observed during a myopic shift in children. This could be related to the changes around the optic nerve head during eyeball elongation. If the biomechanical properties at or around the optic nerve head are changed after exposure to elevated intraocular pressure (IOP in glaucoma eyes, different response of the disc tilting and PPA changes could take place during eyeball elongation by myopic shift. On the basis of this background, the aim of this study was to compare the morphological changes in the optic disc induced by a myopic shift during childhood between normal control eyes, eyes from disc suspects with an enlarged cup-to-disc ratio (CDR, and eyes with childhood glaucoma.Total of 82 eyes from 82 subjects younger than 14 years of age were included in the study. Serial disc photographs were classified into one of two groups: eyes with an optic nerve head (ONH or peripapillary atrophy (PPA change or without an ONH/PPA change. Using ImageJ software, the outlines of the optic disc and PPA were plotted, and the vertical disc diameter (VDD, horizontal disc diameter (HDD, and maximum PPA width (PPW were measured. The changes in the ratios of these parameters and the relationships between the degree of myopic shift or the ONH/PPA change were analyzed.Twenty-five eyes with normal optic disc appearance, 36 eyes with enlarged cup-to-disc ratio, and 21 eyes of glaucoma patients were analyzed. The initial intraocular pressure (IOP at diagnosis was significantly different among the groups (P<0.001. The degree of myopic shift during follow-up period was not significantly different among the groups (P=0.612. However, the changes in the HDD/VDD and PPW/VDD ratios were significantly greater in the disc suspect group and significantly smaller in the glaucoma group. Among the 42 eyes with an ONH/PPA change, 16 (38.1% were from the normal control group, 24 (57.1% were

    2017-01-01

    Full Text Available Fungal infections as a result of freshwater exposure or trauma are fortunately rare. Etiologic agents are varied, but commonly include filamentous fungi and Candida. This narrative review describes various sources of potential freshwater fungal exposure and the diseases that may result, including fungal keratitis, acute otitis externa and tinea pedis, as well as rare deep soft tissue or bone infections and pulmonary or central nervous system infections following traumatic freshwater exposure during natural disasters or near-drowning episodes. Fungal etiology should be suspected in appropriate scenarios when bacterial cultures or molecular tests are normal or when the infection worsens or fails to resolve with appropriate antibacterial therapy.

    The major part of the eye consists of water . Continuous movement of water and ions between the ocular compartments and to the systemic circulation is pivotal for many physiological functions in the eye. The movement of water facilitates removal of the many metabolic products of corneal-, ciliary...... pressure. In the retina, water is transported into the vitreous body and across the retinal pigment epithelium to regulate the extracellular environment and the hydration of the retina.

    2017-09-05

    Eye movements provide insights about a wide range of brain functions, from sensorimotor integration to cognition; hence, the measurement of eye movements is an important tool in neuroscience research. We describe a method, based on magnetic sensing, for measuring eye movements in head-fixed and freely moving mice. A small magnet was surgically implanted on the eye, and changes in the magnet angle as the eye rotated were detected by a magnetic field sensor. Systematic testing demonstrated high resolution measurements of eye position of eye tracking offers several advantages over the well-established eye coil and video-oculography methods. Most notably, it provides the first method for reliable, high-resolution measurement of eye movements in freely moving mice, revealing increased eye movements and altered binocular coordination compared to head-fixed mice. Overall, magnetic eye tracking provides a lightweight, inexpensive, easily implemented, and high-resolution method suitable for a wide range of applications.

  5. Diagnosis and management of red eye in primary care.

    Science.gov (United States)

    Cronau, Holly; Kankanala, Ramana Reddy; Mauger, Thomas

    2010-01-15

    Red eye is the cardinal sign of ocular inflammation. The condition is usually benign and can be managed by primary care physicians. Conjunctivitis is the most common cause of red eye. Other common causes include blepharitis, corneal abrasion, foreign body, subconjunctival hemorrhage, keratitis, iritis, glaucoma, chemical burn, and scleritis. Signs and symptoms of red eye include eye discharge, redness, pain, photophobia, itching, and visual changes. Generally, viral and bacterial conjunctivitis are self-limiting conditions, and serious complications are rare. Because there is no specific diagnostic test to differentiate viral from bacterial conjunctivitis, most cases are treated using broad-spectrum antibiotics. Allergies or irritants also may cause conjunctivitis. The cause of red eye can be diagnosed through a detailed patient history and careful eye examination, and treatment is based on the underlying etiology. Recognizing the need for emergent referral to an ophthalmologist is key in the primary care management of red eye. Referral is necessary when severe pain is not relieved with topical anesthetics; topical steroids are needed; or the patient has vision loss, copious purulent discharge, corneal involvement, traumatic eye injury, recent ocular surgery, distorted pupil, herpes infection, or recurrent infections.

    Zhou, Zhi; Du, Yingzi; Thomas, N. L.; Delp, Edward J., III

    2010-04-01

    Multimodal biometrics use more than one means of biometric identification to achieve higher recognition accuracy, since sometimes a unimodal biometric is not good enough used to do identification and classification. In this paper, we proposed a multimodal eye recognition system, which can obtain both iris and sclera patterns from one color eye image. Gabor filter and 1-D Log-Gabor filter algorithms have been applied as the iris recognition algorithms. In sclera recognition, we introduced automatic sclera segmentation, sclera pattern enhancement, sclera pattern template generation, and sclera pattern matching. We applied kernelbased matching score fusion to improve the performance of the eye recognition system. The experimental results show that the proposed eye recognition method can achieve better performance compared to unimodal biometric identification, and the accuracy of our proposed kernel-based matching score fusion method is higher than two classic linear matching score fusion methods: Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA).

    To describe the pattern and progression of central nervous system (CNS) lesions in microcephalic fetuses with suspected Zika virus (ZIKV) infection. In this prospective study in Salvador, Brazil, we analyzed fetuses diagnosed with microcephaly and suspected ZIKV infection after a routine primary care ultrasound scan between July 2015 and February 2016 raised suspicion of fetal microcephaly. The pregnancies were followed with serial ultrasound scans until delivery at one of the three main referral centers for fetal abnormalities in Salvador, Brazil. Microcephaly was diagnosed when the head circumference was two or more SDs below the mean for gestational age and its relationship with ZIKV infection was defined according to the World Health Organization's criteria. All women were interviewed, to assess potential factors associated with fetal microcephaly. Serology test results for toxoplasmosis, cytomegalovirus, rubella, syphilis and human immunodeficiency virus (HIV) were recorded, as were previous routine ultrasound results. Signs/symptoms of infection during the pregnancy were noted. Of 60 cases of suspected ZIKV-related fetal microcephaly seen during the study period, eight were excluded due to serological evidence of other congenital infections or major ultrasound chromosomal markers. In the remaining 52 fetuses, microcephaly was diagnosed between 19 and 40 (median, 27.7; interquartile range, 23.4-32.0) weeks of gestation. The main ultrasound findings were: ventriculomegaly (65.4% of cases), cerebral calcifications (44.2%) and posterior fossa abnormalities (32.7%). 9.6% presented with arthrogryposis as an associated finding. Microcephaly was an isolated finding in four cases (7.7%). While ventriculomegaly was progressive in 41.2% of cases with this finding, the velocity of head circumference increase decreased progressively in almost all cases. Exanthematic disease was present in the majority (86.5%) of the women, 67.3% presenting in the first trimester of

    2010-05-01

    Increasing the number of suspects who give true confessions of sexual abuse serves justice and reduces the burden of the criminal justice process on child victims. With data from four communities, this study examined confession rates and predictors of confession of child sexual abuse over the course of criminal investigations (final N = 282). Overall, 30% of suspects confessed partially or fully to the crime. This rate was consistent across the communities and is very similar to the rates of suspect confession of child sexual abuse found by previous research, although lower than that from a study focused on a community with a vigorous practice of polygraph testing. In a multivariate analysis, confession was more likely when suspects were younger and when more evidence of abuse was available, particularly child disclosure and corroborative evidence. These results suggest the difficulty of obtaining confession but also the value of methods that facilitate child disclosure and seek corroborative evidence, for increasing the odds of confession.

    2013-11-01

    Several research studies have reported an elevated level of aggression in rapes committed by multiple perpetrators compared to rapes committed by lone suspects. Several factors that have been linked to elevated aggression in generic samples of rape were examined for the first time with a sample of multiple perpetrator rapes. Factors that might be associated with victim resistance were also investigated. Victim and offender characteristics, as well as the behaviors displayed by victims and offenders, were extracted from the police files of 89 multiple perpetrator stranger rapes perpetrated against female victims in the United Kingdom. These behaviors were rated for their level of suspect (non-sexual) aggression and victim resistance, respectively. Degree of victim resistance was significantly and positively associated with suspect aggression. Older victims were the recipients of significantly higher levels of suspect aggression. Victims who were incapacitated from drugs and/or alcohol were less likely to be the recipients of suspect aggression. Group leaders displayed more aggression towards the victim than the followers in the groups. The number of perpetrators was significantly related to the degree of resistance displayed by the victim with offences perpetrated by fewer suspects being characterized by more victim resistance. Research regarding cognitive appraisal during criminal interactions and the respective roles of offenders is referred to in considering these relationships.

    In this article we introduce a novel interviewing tactic to elicit admissions from guilty suspects. By influencing the suspects' perception of the amount of evidence the interviewer holds against them, we aimed to shift the suspects' counterinterrogation strategies from less to more forthcoming. The proposed tactic (SUE-Confrontation) is a development of the Strategic Use of Evidence (SUE) framework and aims to affect the suspects' perception by confronting them with statement-evidence inconsistencies. Participants (N = 90) were asked to perform several mock criminal tasks before being interviewed using 1 of 3 interview techniques: (a) SUE-Confrontation, (b) Early Disclosure of Evidence, or (c) No Disclosure of Evidence. As predicted, the SUE-Confrontation interview generated more statement-evidence inconsistencies from suspects than the Early Disclosure interview. Importantly, suspects in the SUE-Confrontation condition (vs. Early and No disclosure conditions) admitted more self-incriminating information and also perceived the interviewer to have had more information about the critical phase of the crime (the phase where the interviewer lacked evidence). The findings show the adaptability of the SUE-technique and how it may be used as a tool for eliciting admissions. (c) 2015 APA, all rights reserved).

    Parents of children who presented for a pediatrics appointment responded to a clinical vignette that described a child with symptoms consistent with acute viral conjunctivitis. In a 2 × 2 randomized survey design, the physician in the vignette either used the term "pink eye" or "eye infection" to describe the symptoms, and either told parents that antibiotics are likely ineffective at treating the symptoms or did not discuss effectiveness. When the symptoms were referred to as "pink eye," parents remained interested in antibiotics, despite being informed about their ineffectiveness. By contrast, when the symptoms were referred to as an "eye infection," information about antibiotic ineffectiveness significantly reduced interest, Mdiff = 1.63, P pink eye" label also thought that the symptoms were more contagious and were less likely to believe that their child could go to child care, compared with parents who received the "eye infection" label, Mdiff = 0.37, P = .38. © The Author(s) 2015.

    Full Text Available Objective: There are contradictory reports about the use of adenosine deaminase (ADA as a diagnostic marker intuberculous peritonitis patients. Reports evaluating significance of ADA activity in the diagnosis of tuberculous peritonitisin adults are lacking in Nepal. We thus set out to investigate the ascitic fluid ADA levels in suspected tuberculousperitonitis patients and to determine the diagnostic significance of the test statistically.Methods: This study population comprised of two different adult patients groups. Group I - 35 suspected cases oftuberculous peritonitis and Group II - 35 cases of transudative ascites - the control group (patients with biochemicallyproved transudates or hypoproteinaemia and peritoneal tap was done. ADA estimation was carried out by spectrophotometry.Results: ADA levels (Mean ± SD in suspected tuberculous peritonitis and transudative ascites cases were 48.5±17.9U/L and 19.8±7.7 U/L respectively (P<0.001. In the receiver operating characteristic (ROC curve for ascites, ADA cut-offlevel of 41.5 U/L was found to yield the best results of differential diagnosis; sensitivity, specificity, positive predictivevalue, negative predictive value and accuracy of the test in tuberculous peritonitis cases were 80.0%, 97.2 %, 96.6%,82.9%, 88.6% respectively.Conclusion: ADA levels are elevated in suspected tuberculous peritonitis cases and it is a simple, rapid, inexpensiveand the least invasive test. It is thus a useful biochemical marker for the early diagnosis of tuberculous peritonitis whilewaiting for the results of mycobacterial cultures or biopsies.

    2017-05-01

    In forensic investigations, suspects sometimes conceal recognition of a familiar person to protect co-conspirators or hide knowledge of a victim. The current experiment sought to determine whether eye fixations could be used to identify memory of known persons when lying about recognition of faces. Participants' eye movements were monitored whilst they lied and told the truth about recognition of faces that varied in familiarity (newly learned, famous celebrities, personally known). Memory detection by eye movements during recognition of personally familiar and famous celebrity faces was negligibly affected by lying, thereby demonstrating that detection of memory during lies is influenced by the prior learning of the face. By contrast, eye movements did not reveal lies robustly for newly learned faces. These findings support the use of eye movements as markers of memory during concealed recognition but also suggest caution when familiarity is only a consequence of one brief exposure.

  16. The frontal eyes of crustaceans.

    2006-12-01

    Frontal eyes of crustaceans (previously called nauplius eye and frontal organs) are usually simple eyes that send their axons to a medial brain centre in the anterior margin of the protocerebrum. Investigations of a large number of recent species within all major groups of the Crustacea have disclosed four kinds of frontal eyes correlated with taxonomic groups and named after them as the malacostracan, ostracod-maxillopodan, anostracan, and phyllopodan frontal eyes. The different kinds of eyes have been established using the homology concept coined by Owen [Owen, R., 1843. Lectures on the comparative anatomy and physiology of the invertebrate animals. Longman, Brown, Green, Longmans, London] and the criteria for homology recommended by Remane [Remane, A., 1956. Die Grundlagen des natürlichen Systems, der vergleichenden Anatomie und der Phylogenetik. 2nd ed. Akademische Verlagsgesellschaft, Geest und Portig, Leipzig]. Common descent is not used as a homology criterion. Frontal eyes bear no resemblance to compound eyes and in the absence of compound eyes, as in the ostracod-maxillopodan group, frontal eyes develop into complicated mirror, lens-mirror, and scanning eyes. Developmental studies demonstrate widely different ways to produce frontal eyes in phyllopods and malacostracans. As a result of the studies of recent frontal eyes in crustaceans, it is concluded by extrapolation that in crustacean ancestors four non-homologous frontal eye types evolved that have remained functional in spite of concurrent compound eyes.

    Full Text Available Purpose: To report a case of varicella-zoster virus (VZV keratitis with detection of VZV DNA in the tear fluid of not only the symptomatic eye but also the contralateral asymptomatic eye by polymerase chain reaction (PCR. Methods: This is a case report. A 63-year-old otherwise healthy woman presented with circular corneal ulcer and stromal opacity with infiltration accompanied by mild conjunctival and ciliary injections in the left eye. Bacterial cultures of the corneal scrapings and virus PCR analyses of tear fluid from both eyes were performed. Results: No pathogen was found by bacterial cultures. PCR was negative for Acanthamoeba, herpes simplex virus and cytomegalovirus, but positive for VZV. VZV DNA was also detected in the unaffected eye. Based on the diagnosis of VZV keratitis, oral valacyclovir and acyclovir eye ointment were administered to the corneal infected eye. The infected eye was healed and VZV DNA turned negative in the tear fluid of the treated eye after 6 months of treatment; however, VZV DNA was still positive in the tear fluid of the contralateral eye. Conclusions: To our knowledge, this is the first case report of the detection of VZV DNA in the tear fluid of both affected and unaffected eyes in a patient with VZV keratitis. Asymptomatic conjunctival shedding of VZV may continue in the healthy unaffected eye in VZV keratitis patients.

    Diabetic foot infection DFI is simply defined as suspected or documented infection of the tissues that comprise the foot of a diabetic patient. Diabetic foot infection is often caused by introduction of an infection into the otherwise sterile soft tissues of the foot through a minor skin break down. Diabetic foot infection may be mild usually restricted to the uppermost layers of the skin, moderate extending down to the soft tissues of the foot or severe infection associated with systemic toxicity or metabolic instability. The paper reviews the types of DFI, pathophysiology, microbiology of DFI, relevant anatomy of the foot, clinical evaluation, measures of severity of DFI, the role of radiological investigations, and the role of early surgical intervention in the prevention of progressive foot infection and limb salvage. It is concluded that the diagnosis of DFI should be suspected at an early stage based on the presence of local signs of inflammation with or without systemic signs of toxicity or metabolic instability. Optimal treatment of DFI requires a multimodality approach directed at controlling hyperglycemia, administration of systemic antibiotics, and local wound management to prevent the spread and dissemination of infection.

    A prospective study involving all casualty departments in Trent Region and 81% of the major eye units in UK was performed to determine ocular morbidity from the use of fireworks during 1986. A serious injury was defined as involving admission to hospital and/or intraocular damage. Of all the injuries from fireworks, 16.7% seen at major eye units were serious and were caused by rockets or exploding fireworks (P less than 0.001). Only 53% of all injuries and 12.5% of serious injuries involved children, and in contrast to the 1950s and early 1960s, young adults appear at greatest risk in the 1980s. Legislation to reduce ocular morbidity should concentrate on restricting the use of rockets and exploding fireworks and encouraging the use of suitable eye protection. PMID:3184088

  2. Strategies for diagnosis and treatment of suspected leptospirosis: a cost-benefit analysis.

    Directory of Open Access Journals (Sweden)

    Yupin Suputtamongkol

    Full Text Available BACKGROUND: Symptoms and signs of leptospirosis are non-specific. Several diagnostic tests for leptospirosis are available and in some instances are being used prior to treatment of leptospirosis-suspected patients. There is therefore a need to evaluate the cost-effectiveness of the different treatment strategies in order to avoid misuse of scarce resources and ensure best possible health outcomes for patients. METHODS: The study population was adult patients, presented with uncomplicated acute febrile illness, without an obvious focus of infection or malaria or typical dengue infection. We compared the cost and effectiveness of 5 management strategies: 1 no patients tested or given antibiotic treatment; 2 all patients given empirical doxycycline treatment; patients given doxycycline when a patient is tested positive for leptospirosis using: 3 lateral flow; 4 MCAT; 5 latex test. The framework used is a cost-benefit analysis, accounting for all direct medical costs in diagnosing and treating patients suspected of leptospirosis. Outcomes are measured in length of fever after treatment which is then converted to productivity losses to capture the full economic costs. FINDINGS: Empirical doxycycline treatment was the most efficient strategy, being both the least costly alternative and the one that resulted in the shortest duration of fever. The limited sensitivity of all three diagnostic tests implied that their use to guide treatment was not cost-effective. The most influential parameter driving these results was the cost of treating patients with complications for patients who did not receive adequate treatment as a result of incorrect diagnosis or a strategy of no-antibiotic-treatment. CONCLUSIONS: Clinicians should continue treating suspected cases of leptospirosis on an empirical basis. This conclusion holds true as long as policy makers are not prioritizing the reduction of use of antibiotics, in which case the use of the latex test would be

    Acute infective endocarditis is a potentially life-threatening disease. Its outcome strongly depends on systemic embolization and extracardiac infections. When present, these conditions usually lead to a more aggressive therapeutic approach. However, the diagnosis of peripheral septic embolism is very challenging. {sup 18}F-Fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT has proven to be accurate for the detection of inflammatory diseases and occult infections. The aim of this study was to assess the added value of {sup 18}F-FDG PET/CT in the detection of extracardiac embolisms in the evaluation of patients with suspected valvular endocarditis (VE). Seventy-one patients with suspected infective endocarditis, enrolled between June 2010 and December 2012, underwent {sup 18}F-FDG PET/CT with the standard procedure on a dedicated PET/CT scanner. Extracardiac findings were subsequently evaluated with other imaging procedures. Of the 71 patients with suspicion of infective endocarditis, we found unexpected extracardiac findings in 17 patients (24 %) without any clinical suspicion. Extracardiac findings were subsequently evaluated with other imaging procedures. PET/CT detected unexpected extra sites of infection in 24 % of cases, leading to changes in therapeutic management in a very relevant percentage of patients. These findings may have important therapeutic implications. (orig.)

    Worrell, Emma

    A new technique to produce hollow prostheses is presented. A small case series of patients utilized standard methods to fabricate hollow ocular prostheses where rehabilitation had proved difficult. This article describes the fabrication and results of hollow ocular prostheses. Each hollow eye was significantly reduced in weight, one-third lighter than the original weight, with the exact size, shape, and volume of the existing solid prosthesis. This simple design significantly reduced the weight of these eyes and revolutionized these patients' rehabilitation. Previously the solid prostheses overburdened the lower eyelids, causing discomfort, irritation, discharge, and reddening, whereas the new lightweight prostheses are unobtrusive, comfortable, and good aesthetically.

    Red eye in children is a common consultation purpose. Mostly benign, this sign may also cause visual impairment. We differentiate three kinds of red eye: localised, diffused and perikeratic injection. The last one must be recognized because of its association with severe ocular diseases. Diagnosis must be sure and treatment has to be efficient to not pertubate childrens visual development. Unfortunately, physical examination on children is not always easy. Consultation with an ophthalmologist is justified if a doubt remains, in case of chronic pathology or resistance to first intention treatment.

    Full Text Available The focus of this review are allergic complications following insertion of metallic orthopedic implants. Such potential allergic reactions encompass eczema, impaired wound and fracture healing, infection-mimicking reactions, effusions, pain and loosening. Nickel, cobalt and chromium seem to be the predominant eliciting allergens. Allergy might be considered prior to planned orthopaedic surgery or in patients with complications following arthroplasty We recommend, that differential diagnoses - in particular infection -should always be excluded in cooperation with surgery collegues. The clinical work up of a patient suspected of suffering from metal implant allergy should include a combined evaluation of medical history, clinical findings, patch testing and histology In vitro testing, namely the lymphocyte transformation test (LTT, can indicate metal sensitization, but needs careful interpretation.

    A new method for quantitative evaluation of ultrasonic scanograms of the eye, that permits differentiation between retinoblastoma and Coats' retinitis, was employed in echographic examinations of the eyes in 21 children with suspected intraocular volumic processes. Image analysis by plotting and processing of histogram was employed. High-confidence differences in the 'excess' and 'skewness' meanings of gradient histograms of patients with these two conditions have been detected.

    2017-07-01

    This article addresses the etiology of red eyes and a novel case of food-induced red eye. An 82-year-old white male patient reported 50 years of episodes of severe unilateral bulbar injection in either eye following ingestion of certain foods. Thinned scleras in this particular patient made the injection in his eyes more observable. Photodocumentation of this reaction after he ingested these foods is shown. It is hypothesized that this is a new explanation for an intermittent, unilateral, self-limited red eye-a food-induced red eye.

    Deep neck infection is relatively rare but potentially life threatening complication of common oropharyngeal infections. This retrospective study was aimed at analyzing the occurrence of complications, diagnostic methods and proper management of deep neck infection. A review was conducted in 32 cases who were diagnosed as having deep neck infection from 1995 to 2005. The causes of deep neck infections were tonsillitis (16 cases), tooth diseases (6 cases), paratonsillar abscess (4 cases), parotitis (1 case), pussy lymphonodes after tonsillectomy (2 cases), pussy congenital neck cyst (1 case), chronic otitis media (1 case), parotitis (1 case), foreign body of the esophagus (1 case). All the puss bacterial cultivation were positive. All the patients were treated by different ways of chirurgical drainage and use of large dosage of antibiotics. Deep neck infection should be suspected in patients with long lasting fever and painful swelling of the neck and treatment should begin quick as possible.

  13. NGC6543: Cat's Eye and Bull's Eye

    Science.gov (United States)

    Balick, B.; Wilson, J. M.

    2000-05-01

    Deep Hubble images of NGC 6543 reveal a series of regularly spaced circular concentric ``rings'' that surround the famous Cat's Eye nebula. The rings seen in the lines of Hα , [O III], and [N II] but not the continuum. These photoionized rings are almost certainly the result of periodic spherical mass pulsations by the nucleus before the Cat's Eye formed. A good fit to the observed Hα surface brightness distribution is obtained if the bubbles were ejected with constant mass, thickness, and ejection velocity. The model can be used to estimate the total mass of the rings, ~ 0.1M⊙ , which lies between that of the core ( ~ 0.05 M⊙ ) and the surrounding halo ( ~ 0.5 M⊙ ). Assuming an ejection speed of 10 km s-1 the interpulse period is 1500 +/- 300 y, the same as the expansion age of the core itself. Hubble images of other planetaries displayed on the poster, IC 418, NGC 7027, and Hubble 5 (a bipolar) show similar sets of multiple concentric rings. Hence, it appears, regular isotropic AGB mass pulses often precede the formation of brighter and more complex PN cores. However, the interpulse time scale, ~ 103 y, is a serious problem for extant models of core thermal pulses and surface pulsations. The cores of PNe seem to form in an abrupt change of mode of mass loss, as predicted by disrputive binary companion merger models.

    Science.gov (United States)

    De Laey, Jean J

    2011-05-01

    In the time of Vesalius, knowledge of ocular anatomy was limited. The first description of the anatomy of the eye comes from Democrites, for whom the eye was surrounded by two 'coats', filled with a homogenous fluid. The optic nerve was hollow and the lens was considered to be a postmortem artefact. Until the 15th century AD, medicine was influenced by the writings of Galenus and the model of the eye he proposed was still considered valid, even after Vesalius. According to the Alexandrian tradition, the lens was considered as the seat of visual perception. Although Vesalius rightly deserves the title of father of modern anatomy, his description of ocular anatomy was rudimentary and often incorrect. He described a musculus retractorius bulbi, which is found only in lower mammals, not in primates. The lens, the role of which as an optical device he recognized correctly, was placed too centrally in the eye. The optic nerve was not correctly placed and, following Galenus, Vesalius described only seven cranial nerves. The Galenian concept of ocular anatomy was to endure until the development of the microscope by Anthony van Leeuwenhoek. Modern ocular anatomy, in fact, can be dated from the works of Zinn. © 2010 The Author. Journal compilation © 2010 Acta Ophthalmol.

  16. Pursuit Eye Movements

    Science.gov (United States)

    Krauzlis, Rich; Stone, Leland; Null, Cynthia H. (Technical Monitor)

    1998-01-01

    When viewing objects, primates use a combination of saccadic and pursuit eye movements to stabilize the retinal image of the object of regard within the high-acuity region near the fovea. Although these movements involve widespread regions of the nervous system, they mix seamlessly in normal behavior. Saccades are discrete movements that quickly direct the eyes toward a visual target, thereby translating the image of the target from an eccentric retinal location to the fovea. In contrast, pursuit is a continuous movement that slowly rotates the eyes to compensate for the motion of the visual target, minimizing the blur that can compromise visual acuity. While other mammalian species can generate smooth optokinetic eye movements - which track the motion of the entire visual surround - only primates can smoothly pursue a single small element within a complex visual scene, regardless of the motion elsewhere on the retina. This ability likely reflects the greater ability of primates to segment the visual scene, to identify individual visual objects, and to select a target of interest.

  17. The use of psychoactive prescription drugs among DUI suspects.

    The study seeks to increase understanding of the use of psychoactive prescription drugs among persons suspected of driving under the influence (DUI). We studied whether the use of prescribed psychoactive medication was associated with DUI, and examined the difference in the use of prescription drugs between DUI recidivists and those arrested only once. In this register-based study, persons suspected of DUI (n=29470) were drawn from the Register of DUI suspects, and an age- and gender-matched reference population (n=30043) was drawn from the Finnish general population. Data on prescription drug use was obtained by linkage to the National Prescription Register. The associations of DUI arrest and use of psychoactive prescription drugs in different DUI groups (findings for alcohol only, prescription drugs, prescription drugs and alcohol, illicit drugs) were estimated by using mixed-effect logistic regression. The use of psychoactive prescription drugs and DUI appeared to be strongly associated, with DUI suspects significantly more likely to use psychoactive prescription drugs compared to the reference population. Gender differences existed, with the use of benzodiazepines being more common among female DUI suspects. Moreover, DUI recidivists were more likely to use psychoactive prescription drugs compared to those arrested only once. In addition to alcohol and/or illicit drug use, a significant proportion of DUI suspects were using psychoactive prescription drugs. When prescribing psychoactive medication, especially benzodiazepines, physicians are challenged to screen for possible substance use problems and also to monitor for patients' alcohol or illicit drug use while being medicated.

  19. Infection prevention and control in pediatric ambulatory settings.

    Science.gov (United States)

    2007-09-01

    Since the American Academy of Pediatrics published a statement titled "Infection Control in Physicians' Offices" (Pediatrics. 2000;105[6]:1361-1369), there have been significant changes that prompted this updated statement. Infection prevention and control is an integral part of pediatric practice in ambulatory medical settings as well as in hospitals. Infection prevention and control practices should begin at the time the ambulatory visit is scheduled. All health care personnel should be educated regarding the routes of transmission and techniques used to prevent transmission of infectious agents. Policies for infection prevention and control should be written, readily available, updated annually, and enforced. The standard precautions for hospitalized patients from the Centers for Disease Control and Prevention, with a modification from the American Academy of Pediatrics exempting the use of gloves for routine diaper changes and wiping a well child's nose or tears, are appropriate for most patient encounters. As employers, pediatricians are required by the Occupational Safety and Health Administration to take precautions to identify and protect employees who are likely to be exposed to blood or other potentially infectious materials while on the job. Key principles of standard precautions include hand hygiene (ie, use of alcohol-based hand rub or hand-washing with soap [plain or antimicrobial] and water) before and after every patient contact; implementation of respiratory hygiene and cough-etiquette strategies for patients with suspected influenza or infection with another respiratory tract pathogen to the extent feasible; separation of infected, contagious children from uninfected children when feasible; safe handling and disposal of needles and other sharp medical devices and evaluation and implementation of needle-safety devices; appropriate use of personal protective equipment such as gloves, gowns, masks, and eye protection; and appropriate sterilization

  20. Effectiveness of a fluid chart in outpatient management of suspected dengue fever: A pilot study.

    2017-01-01

    Dengue infection is the fastest spreading mosquito-borne viral disease in the world. One of the complications of dengue is dehydration which, if not carefully monitored and treated, may lead to shock, particularly in those with dengue haemorrhagic fever. WHO has recommended oral fluid intake of five glasses or more for adults who are suspected to have dengue fever. However, there have been no published studies looking at self-care intervention measures to improve oral fluid intake among patients suspected of dengue fever. To assess the feasibility and effectiveness of using a fluid chart to improve oral fluid intake in patients with suspected dengue fever in a primary care setting. This feasibility study used a randomized controlled study design. The data was collected over two months at a primary care clinic in a teaching hospital. The inclusion criteria were: age > 12 years, patients who were suspected to have dengue fever based on the assessment by the primary healthcare clinician, fever for > three days, and thrombocytopenia (platelets chart and a cup (200ml). Baseline clinical and laboratory data, 24-hour fluid recall (control group), and fluid chart were collected. The main outcomes were: hospitalization rates, intravenous fluid requirement and total oral fluid intake. Among the 138 participants who were included in the final analysis, there were fewer hospital admissions in the intervention group (n = 7, 10.0%) than the control group (n = 12, 17.6%) (p = 0.192). Similarly, fewer patients (n = 9, 12.9%) in the intervention group required intravenous fluid compared to the control group (n = 15, 22.1%), (p = 0.154). There was an increase in the amount of daily oral fluid intake in the intervention group (about 3,000 ml) compared to the control group (about 2,500 ml, p = 0.521). However, these differences did not reach statistical significance. This is a feasible and acceptable study to perform in a primary care setting. The fluid chart is a simple, inexpensive

    Rhinoliths are rare, intranasal, mineralized masses formed via the precipitation of mineral salts around an intranasal nidus. Clinical signs are typically consistent with inflammatory rhinitis and nasal obstruction, but asymptomatic cases are possible. Rhinoliths may be classified as exogenous or endogenous depending on the origin of the nidus, with endogenous rhinoliths reportedly being less common. This case report describes a suspected case of endogenous rhinolithiasis in a cat which was detected as an incidental finding during radiographic assessment of a maxillary canine tooth with endodontic disease. Treatment consisted of removal of the suspected rhinolith via a transalveolar approach after surgical extraction of the maxillary canine tooth.

  4. HTLV-1 and neurological conditions: when to suspect and when to order a diagnostic test for HTLV-1 infection? Doenças neurológicas e infecção pelo HTLV-1: quando suspeitar e quando solicitar testes diagnósticos para a infecção pelo HTLV-1

    Directory of Open Access Journals (Sweden)

    Abelardo Q.C. Araújo

    2009-03-01

    Full Text Available HTLV-1 is a retrovirus associated with a myriad of clinical conditions, especially hematological and neurological ones. Regarding nervous system diseases, it is of utmost importance to select those cases in which HTLV-1 infection could really be associated. This is particularly true for patients from endemic areas and for HIV-infected patients and drug users, since that these groups are at a higher risk for HTLV infection. This caution in selecting neurological patients for HTLV diagnostic tests is justified by the fact that in some circumstances the seropositivity may merely represent an epiphenomenon. In this paper we enroll some neurological conditions that have been associated with HTLV-1/2 infection in the literature and discuss the real need for HTLV-1/2 diagnostic tests in each one. Because HIV/HTLV-co-infected patients seem to be at an increased risk for neurological diseases development, a special consideration about this matter is also made.O HTLV-1 é um retrovírus associado tanto a doenças hematológicas quanto a doenças neurológicas. Em relação às doenças neurológicas, é fundamental que selecionemos aquelas em que de fato a infecção pelo HTLV-1 possa ser a causa. Isto é particularmente verdadeiro nos pacientes oriundos de áreas endêmicas e nos pacientes infectados pelo HIV e usuários de drogas, haja vista que estes grupos são de risco para infecção pelo HTLV. Este cuidado ao selecionarmos aquelas condições neurológicas que merecem ser investigadas com sorologia para o HTLV se justifica pelo fato de que nem sempre podemos afastar uma associação fortuita entre a infecção e a referida doença. Neste artigo, comentaremos sobre algumas condições neurológicas que podem estar associadas com a infecção pelo HTLV-1/2, discutindo a real necessidade de solicitar testes para o diagnóstico da infecção pelo HTLV-1/2 frente a elas. Uma breve consideração sobre a co-infecção HIV/HTLV será feita no final deste

  6. Unilateral Amblyopia Affects Two Eyes: Fellow Eye Deficits in Amblyopia.

    Science.gov (United States)

    Meier, Kimberly; Giaschi, Deborah

    2017-03-01

    Unilateral amblyopia is a visual disorder that arises after selective disruption of visual input to one eye during critical periods of development. In the clinic, amblyopia is understood as poor visual acuity in an eye that was deprived of pattern vision early in life. By its nature, however, amblyopia has an adverse effect on the development of a binocular visual system and the interactions between signals from two eyes. Visual functions aside from visual acuity are impacted, and many studies have indicated compromised sensitivity in the fellow eye even though it demonstrates normal visual acuity. While these fellow eye deficits have been noted, no overarching theory has been proposed to describe why and under what conditions the fellow eye is impacted by amblyopia. Here, we consider four explanations that may account for decreased fellow eye sensitivity: the fellow eye is adversely impacted by treatment for amblyopia; the maturation of the fellow eye is delayed by amblyopia; fellow eye sensitivity is impacted for visual functions that rely on binocular cortex; and fellow eye deficits reflect an adaptive mechanism that works to equalize the sensitivity of the two eyes. To evaluate these ideas, we describe five visual functions that are commonly reported to be deficient in the amblyopic eye (hyperacuity, contrast sensitivity, spatial integration, global motion, and motion-defined form), and unify the current evidence for fellow eye deficits. Further research targeted at exploring fellow eye deficits in amblyopia will provide us with a broader understanding of normal visual development and how amblyopia impacts the developing visual system.

Next, we provide an overview of eye movement behavior during reading, scene perception, and visual search, since each of these activities is, at various times, involved in viewing ads. We then review the literature on eye movements when viewing print ads and warning labels (of the kind ...

    The Zika virus (ZIKV) has rapidly reached epidemic proportions, especially in northeastern Brazil, and has rapidly spread to other parts of the Americas. A recent increase in the prevalence of microcephaly in newborn infants and vision-threatening findings in these infants is likely associated with the rapid spread of ZIKV. To evaluate the ocular findings in infants with microcephaly associated with presumed intrauterine ZIKV infection in Salvador, Bahia, Brazil. Case series at a tertiary hospital. Twenty-nine infants with microcephaly (defined by a cephalic circumference of ≤32 cm) with a presumed diagnosis of congenital ZIKV were recruited through an active search and referrals from other hospitals and health unities. The study was conducted between December 1 and December 21, 2015. All infants and mothers underwent systemic and ophthalmic examinations from December 1 through December 21, 2015, in the Roberto Santos General Hospital, Salvador, Brazil. Anterior segment and retinal, choroidal, and optic nerve abnormalities were documented using a wide-field digital imaging system. The differential diagnosis included toxoplasmosis, rubella, cytomegalovirus, herpes simplex virus, syphilis, and human immunodeficiency virus, which were ruled out through serologic and clinical examinations. Ocular abnormalities associated with ZIKV. Twenty-three of 29 mothers (79.3%) reported suspected ZIKV infection signs and symptoms during pregnancy, 18 in the first trimester, 4 in the second trimester, and 1 in the third trimester. Of the 29 infants (58 eyes) examined (18 [62.1%] female), ocular abnormalities were present in 17 eyes (29.3%) of 10 children (34.5%). Bilateral findings were found in 7 of 10 patients presenting with ocular lesions, the most common of which were focal pigment mottling of the retina and chorioretinal atrophy in 11 of the 17 eyes with abnormalities (64.7%), followed by optic nerve abnormalities in 8 eyes (47.1%), bilateral iris coloboma in 1 patient (2

  16. DNA typing from vaginal smear slides in suspected rape cases

    Directory of Open Access Journals (Sweden)

    Dayse Aparecida da Silva

    Full Text Available In an investigation of suspected rape, proof of sexual assault with penetration is required. In view of this, detailed descriptions of the genitalia, the thighs and pubic region are made within the forensic medical service. In addition, vaginal swabs are taken from the rape victim and some of the biological material collected is then transferred to glass slides. In this report, we describe two rape cases solved using DNA typing from cells recovered from vaginal smear slides. In 1999, two young women informed the Rio de Janeiro Police Department that they had been victims of sexual assaults. A suspect was arrested and the victims identified him as the offender. The suspect maintained that he was innocent. In order to elucidate these crimes, vaginal smear slides were sent to the DNA Diagnostic Laboratory for DNA analysis three months after the crimes, as unique forensic evidence. To get enough epithelial and sperm cells to perform DNA analysis, we used protocols modified from the previously standard protocols used for DNA extraction from biological material fixed on glass slides. The quantity of cells was sufficient to perform human DNA typing using nine short tandem repeat (STR loci. It was 3.3 billion times more probable that it was the examined suspect who had left sperm cells in the victims, rather than any other individual in the population of Rio de Janeiro.

    Sexual health in survivors of gynecologic cancer has been studied; however, sexual health in these women before treatment has not been thoroughly evaluated. The objective of our study was to describe the pretreatment characteristics of sexual health of women with suspected gynecologic cancer before cancer treatment. We performed a cross-sectional analysis of women with a suspected gynecologic cancer, who were prospectively enrolled in a hospital-based cancer survivorship cohort from August 2012 to June 2013. Subjects completed the validated Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction Questionnaire. Pretreatment sexual health was assessed in terms of sexual interest, desire, lubrication, discomfort, orgasm, enjoyment, and satisfaction. Of 186 eligible women with suspected gynecologic cancer, 154 (82%) completed the questionnaire pretreatment. Mean age was 58.1 ± 13.3 years. Sexual health was poor: 68.3% reported no sexual activity, and 54.7% had no interest in sexual activity. When comparing our study population to the general U.S. population, the mean pretreatment scores for the subdomains of lubrication and vaginal discomfort were similar, while sexual interest was significantly lower and global satisfaction was higher. In a linear regression model, controlling for cancer site, age remained significantly associated with sexual function while cancer site did not. Problems with sexual health are prevalent in women with suspected gynecologic malignancies before cancer treatment. Increasing awareness of the importance of sexual health in this population will improve quality of life for these women.

    Infection of the lungs and airways by viral, bacterial, fungal and protozoal agents, often producing atypical radiographic features, is common in children with human immunodeficiency virus (HIV) infection. Conventional chest radiography and chest CT remain the most useful imaging modalities for evaluation of the immunocompromised patient presenting with a suspected pulmonary infection. In this review the radiological features of acute lung infections in this population are discussed. (orig.)

    To identify the prevalence of patients suspected of drug use according to the nursing professionals' judgement, and compare the behavior of these professionals in opioid administration when there is or there is no suspicion that patient is a drug user. A cross-sectional study with 507 patients and 199 nursing professionals responsible for administering drugs to these patients. The Chi-Square test, Fisher's Exact and a significance level of 5% were used for the analyzes. The prevalence of suspected patients was 6.7%. The prevalence ratio of administration of opioid analgesics 'if necessary' is twice higher among patients suspected of drug use compared to patients not suspected of drug use (p = 0.037). The prevalence of patients suspected of drug use was similar to that of studies performed in emergency departments. Patients suspected of drug use receive more opioids than patients not suspected of drug use. Identificar a prevalência de pacientes com suspeita de uso de drogas conforme opinião de profissionais de enfermagem e comparar a conduta desses profissionais na administração de opioides quando há ou não suspeita de que o paciente seja usuário de drogas. Estudo transversal com 507 pacientes e 199 profissionais de enfermagem responsáveis pela administração de medicamentos a esses pacientes. Para as análises foram utilizados os testes de Qui-Quadrado, Exato de Fisher e um nível de significância de 5%. A prevalência de pacientes suspeitos foi 6,7%. A razão de prevalência de administração de analgésicos opioides "se necessário" é duas vezes maior entre os pacientes suspeitos em relação aos não suspeitos (p=0,037). A prevalência de suspeitos foi semelhante à de estudos realizados em departamentos de emergência. Os suspeitos de serem usuários de drogas recebem mais opioides do que os não suspeitos.

    Marina A Yermalovich

    Full Text Available As a result of successful implementation of the measles/rubella elimination program, the etiology of more and more double negative cases remains elusive. The present study determined the role of different viruses as causative agents in measles or rubella suspected cases in Belarus. A total of 856 sera sent to the WHO National Laboratory between 2009 and 2011 were tested for specific IgM antibodies to measles virus (MV, rubella virus (RV and human parvovirus B19 (B19V. The negatives were further investigated for antibodies to enterovirus (EV and adenovirus (AdV. Children of up to 3 years were tested for IgM antibodies to human herpesvirus 6 (HHV6. A viral etiology was identified in 451 (52.7% cases, with 6.1% of the samples being positive for MV; 2.6% for RV; 26.2% for B19V; 9.7% for EV; 4.6% for AdV; and 3.6% for HHV6. Almost all measles and rubella cases occurred during limited outbreaks in 2011 and nearly all patients were at least 15 years old. B19V, EV and AdV infections were prevalent both in children and adults and were found throughout the 3 years. B19V occurred mainly in 3-10 years old children and 20-29 years old adults. EV infection was most common in children up to 6 years of age and AdV was confirmed mainly in 3-6 years old children. HHV6 infection was mostly detected in 6-11 months old infants. Laboratory investigation of measles/rubella suspected cases also for B19V, EV, AdV and HHV6 allows diagnosing more than half of all cases, thus strengthening rash/fever disease surveillance in Belarus.

  16. Individual serological follow-up of patients with suspected or confirmed abdominal angiostrongyliasis

    Penélope E Palominos

    2008-02-01

    Full Text Available Abdominal angiostrongyliasis (AA is a zoonotic nematode infection caused by Angiostrongylus costaricensis, with widespread occurrence in the Americas. Although the human infection may be highly prevalent, morbidity is low in Southern Brazil. Confirmed diagnosis is based on finding parasitic structures in pathological examination of biopsies or surgical resections. Serology stands as an important diagnostic tool in the less severe courses of the infection. Our objective is to describe the follow up of humoral reactivity every 2-4 weeks up to one year, in six individuals with confirmed (C and ten suspected (S AA. Antibody (IgG detection was performed by ELISA and resulted in gradually declining curves of reactivity in nine subjects (56% (4C + 5S, that were consistently negative in only three of them (2C + 1S after 221, 121 and 298 days. Three individuals (2C + 1S presented with low persistent reacitivity, other two (1C + 1S were serologically negative from the beginning, but also presenting a declining tendency. The study shows indications that abdominal angiostrongyliasis is usually not a persistent infection: although serological negativation may take many months, IgG reactivity is usually declining along time and serum samples pairing may add valuable information to the diagnostic workout.

However, SAP depends on the reliability of the patients’ responses and other external factors; therefore, other technologies have been developed for earlier detection of visual field changes in glaucoma patients. The frequency-doubling perimetry (FDT is believed to detect glaucoma earlier than SAP. The multifocal visual evoked potential (mfVEP is an objective test for functional evaluation.Objective: To evaluate the sensitivity and specificity of FDT and mfVEP tests in normal, suspect, and glaucomatous eyes and compare the monocular and interocuar mf VEP.Methods: Ninety-five eyes from 95 individuals (23 controls, 33 glaucoma suspects, 39 glaucomatous were enrolled. All participants underwent a full ophthalmic examination, followed by SAP, FDT, and mfVEP tests. Results: The area under the curve for mean deviation and pattern standard deviation were 0.756 and 0.761, respectively, for FDT, 0.564 and 0.512 for signal and alpha for interocular mfVEP, and 0.568 and 0.538 for signal and alpha for monocular mfVEP. This difference between monocular and interocular mfVEP was not significant. Conclusion: The FDT matrix was superior to mfVEP in glaucoma detection. The difference between monocular and interocular mfVEP in the diagnosis of glaucoma was not significant. Keywords: standard automated perimetry, electrophysiology, glaucomatous eyes

  18. Incidence of mixed infection in coryza Cases

    Gayatri Rajurkar

    Full Text Available Diseases of the respiratory tract are a significant component of the overall disease incidence in poultry. In many cases, respiratory disease observed in a flock may be a component of a multi-systemic disease or it may be the predominant disease with lesser involvement of other organ systems. In some cases, such as infectious coryza the disease may be limited to the respiratory system, at least initially. Various pathogens may initiate respiratory disease in poultry, including a variety of viruses, bacteria, and fungi. Environmental factors may augment these pathogens to produce the clinically observed signs and lesions. During present study, an attempt was made to isolate H. paragallinarum from the nasal swabs, eye swabs (from live birds and caseous infra orbital sinus and tracheal exudates swabs from dead birds from commercial poultry farms Anand, Kheda and Mahuaregion of Saurashtra area of Gujrat state.

    1996-08-01

    Magnetic resonance imaging (MRI) has become increasingly useful in the evaluation of musculoskeletal problems, including those of the wrist. In patients with a wrist injury, MRI is used mainly to assess vascularity of scaphoid non-union. However, the use of MRI in patients in the acute phase following carpal injury is not common. Three-phase bone scintigraphy is routinely performed from at least 72 h after injury in patients with suspected scaphoid fracture and negative initial radiographs. We evaluated MRI in this patient group. The bone scan was used as the reference method. Nineteen patients were included. Bone scintigraphy was performed in all 19 patients, but MRI could be obtained in only 16 (in three patients, MRI was stopped owing to claustrophobia). In five patients, MRI confirmed a scintigraphically suspected scaphoid fracture. In one patient, a perilunar luxation, without a fracture, was seen on MRI, while bone scintigraphy showed a hot spot in the region of the lunate bone, suspected for fracture. This was confirmed by surgery. In two patients, a hot spot in the scaphoid region was suspected for scaphoid fracture, and immobilization and employed for a period of 12 weeks. MRI was negative in both cases; in one of them a scaphoid fracture was retrospectively proven on the initial X-ray series. In another two patients, a hot spot in the region of MCP I was found with a negative MRI. In both, the therapy was adjusted. In the remaining six patients, both modalities were negative. We conclude that in the diagnostic management of patients with suspected scaphoid fracture and negative initial radiographs, the use of MRI may be promising, but is not superior to three-phase bone scintigraphy.
