    Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. The diagnosis of classic MF is based on a combination of clinical presentation, histopathology, and T-cell monoclonality detected by molecular studies. However, the diagnosis can be difficult in cases of early MF because of the subtle nature of histologic findings and, in cases of variants of MF, because of the unusual clinical and/or pathologic features. In this review, we presented the most frequent variants of MF at early stage including hypopigmented, folliculotropic, pagetoid reticulosis, unilesional, granulomatous, and ichthyosis forms. This case-based clinicopathologic review provides the notion that a comprehensive clinicopathologic correlation is of substantial importance to render the diagnosis of MF. In addition, we discuss the role of molecular studies, which are highly sensitive and recently more applicable to routinely processed skin biopsy specimens in the diagnosis of MF. PMID:20850703

    Keratosis lichenoides chronica (KLC) is a rare dermatological condition characterized by keratotic papules arranged in a parallel linear or reticular pattern and facial lesions resembling seborrheic dermatitis or rosacea. The clinical, histological and therapeutic information on 71 patients with KLC retrieved through a PubMed search plus one our new case were analyzed. KLC affects patients of all ages, with a modest male predominance. Pediatric cases represent about one quarter of patients. Diagnosis is usually delayed and histologically confirmed. All patients have thick, rough and scaly papules and plaques arranged in a linear or reticular pattern, on limbs (>80%) and trunk (about 60%). Face involvement is described in two-thirds of patients. Lesions are usually asymptomatic or mildly pruritic. Other manifestations, such as palmoplantar keratoderma, mucosal involvement, ocular manifestations, nail dystrophy, are reported in 20-30% of patients. Children present more frequently alopecia. No controlled trials are available. Results from small case series or single case reports show that the best treatment options are phototherapy and systemic retinoids, alone or in combination, with nearly half of patients reaching complete remission. Systemic corticosteroids as well as antibiotics and antimalarials are not effective. PMID:26652284

    Pheochromocytomas are rare tumours originating in chromaffin cells, representing 0.1-1% of all secondary hypertension (HT) cases. The majority are benign and unilateral, characterised by the production of catecholamines and other neuropeptides. Mainly located in the adrenal gland, they are more frequent between the 3rd and 5th decades of life; however, 10-25% can be associated with genetic familial syndromes (multiple endocrine neoplasia type 2 (MEN 2), type 1 neurofibromatosis and Von-Hippel-Landau disease in younger ages. The authors present a rare case of secondary HT due to a pheochromocytoma in a 15-year-old patient, whose metanephrine assay confirmed the diagnosis, and abdominal ultrasound and CT localised the tumour in the adrenal gland. HT was controlled with α and β blockers, with posterior retroperitoneal laparoscopic surgical intervention and subsequent resolution of HT. Age and concomitant hyperparathyroidism compelled genetic testing for the exclusion of MEN 2, which was negative. PMID:26243750

    Necrobiosis lipoidica diabeticorum (NLD) is a rare chronic and granulomatous skin disorder that affects 0.3% of diabetic patients. Although the etiology and pathogenesis of NLD is still controversial, it is thought that microangiopathy has an important role. The legs are the most common site for NLD, but involvement of other areas such as the abdomen, upper extremities and scalp has been reported. There is no rational therapy. However, benefit has been reported from different treatment regimens such as drugs acting on the hemostatic mechanisms, corticosteroid therapy (topical, intralesional and systemic), enhancers of wound healing, surgery and immunomodulating therapies (including photochemotherapy). We report a 59-year-old female, who was a diabetic patient with multiple, disseminated lesions on the legs, which tended to disappear as the glycemic control was achieved. Hereby, we also review the existing literature for the evolving aspects of etiopathogenesis and treatment. PMID:22837927

    2000-05-01

    The paper commences by reviewing the variety of technical approaches to the problem of detecting and diagnosing faulty operation in order to improve the actual performance of buildings. The review covers manual and automated methods, active testing and passive monitoring, the different classes of models used in fault detection, and methods of diagnosis. The process of model-based fault detection is then illustrated by describing the use of relatively simple empirical models of chiller energy performance to monitor equipment degradation and control problems. The CoolTools(trademark) chiller model identification package is used to fit the DOE-2 chiller model to on-site measurements from a building instrumented with high quality sensors. The need for simple algorithms to reject transient data, detect power surges and identify control problems is discussed, as is the use of energy balance checks to detect sensor problems. The accuracy with which the chiller model can be expected! to predict performance is assessed from the goodness of fit obtained and the implications for fault detection sensitivity and sensor accuracy requirements are discussed. A case study is described in which the model was applied retroactively to high-quality data collected in a San Francisco office building as part of a related project (Piette et al. 1999).

  7. Reviewing the development, evidence base, and application of the revised dengue case classification.

    With the example of dengue, an evidence-based approach to prospectively develop a case classification is described, gathering evidence for identifying strength and weaknesses of the existing model, collecting new data describing the disease as it occurs globally, further developing a new model that can be applied in practice and field testing the newly developed model in comparison to the previous model. For each step in this process, the highest available level of evidence has been applied. This process has been initiated by the World Health Organization's (WHO) Special Programme for Research and Training in Tropical Diseases (TDR) and WHO's Department for Control of Neglected Tropical Diseases (NTD), developing the following for dengue. Since the early 1970s, dengue has been classified into dengue fever, dengue haemorrhagic fever grades I and II and dengue shock syndrome grades III and IV (DF/DHF/DSS). However, in recent years, a growing number of dengue clinicians have questioned the shortcomings of this scheme. The issues have revolved around the complexity of confirming DHF in clinical practice, misclassifying severe cases as DF, and the emphasis on haemorrhage rather than plasma leakage as the underlying problem in most severe dengue cases. Step 1: A systematic literature review highlighted the shortcomings of the DF/DHF/DSS scheme: (1) difficulties in applying the criteria for DHF/DSS; (2) the tourniquet test has a low sensitivity for distinguishing between DHF and DF; and (3) most DHF criteria had a large variability in frequency of occurrence. Step 2: An analysis of regional and national dengue guidelines and their application in the clinical practice showed a need to re-evaluate and standardize guidelines as the actual ones showed a large variation of definitions, an inconsistent application by medical staff, and a lack of diagnostic facilities necessary for the DHF diagnosis in frontline services. Step 3: A prospective cohort study in seven countries

    In this paper we describe our approach to understanding wrongdoing in medical research and practice, which involves the statistical analysis of coded data from a large set of published cases. We focus on understanding the environmental factors that predict the kind and the severity of wrongdoing in medicine. Through review of empirical and theoretical literature, consultation with experts, the application of criminological theory, and ongoing analysis of our first 60 cases, we hypothesize that 10 contextual features of the medical environment (including financial rewards, oversight failures, and patients belonging to vulnerable groups) may contribute to professional wrongdoing. We define each variable, examine data supporting our hypothesis, and present a brief case synopsis from our study that illustrates the potential influence of the variable. Finally, we discuss limitations of the resulting framework and directions for future research. PMID:23226933

    2015-01-01

    We treated 21 patients with organizing pneumonia (OP) associated with rheumatoid arthritis (RA) or related to biological disease-modifying antirheumatic drugs (DMARDs) at our institution between 2006 and 2014. Among these cases, 3 (14.3%) preceded articular symptoms of RA, 4 (19.0%) developed simultaneously with RA onset, and 14 (66.7%) occurred during follow-up periods for RA. In the case of OP preceding RA, increased levels of anti-cyclic citrullinated peptide antibodies and rheumatoid factor were observed at the OP onset. RA disease activity was related to the development of OP in the simultaneous cases. In the cases of OP developing after RA diagnosis, 10 of 14 patients had maintained low disease activity with biological DMARD therapy at the OP onset, and among them, 6 patients developed OP within the first year of this therapy. In the remaining four patients, RA activity was not controlled at the OP onset. All patients responded well to systemic steroid therapy, but two patients suffered from relapses of articular and pulmonary symptoms upon steroid tapering. In most of the RA patients, DMARD therapy was introduced or restarted during the steroid tapering. We successfully restarted a biological DMARD that had not been previously used for patients whose RA would otherwise have been difficult to control. In this study, we also perform a review of the literature on RA-associated or biological DMARD-related OP and discuss the pathogenesis and management of OP occurring in RA patients. PMID:26543387

    2016-02-01

    The early years of the acquired immunodeficiency syndrome (AIDS) epidemic introduced the global medical community to Kaposi's sarcoma (KS), a heretofore seldom encountered angiosarcomatous neoplasm associated with human herpesvirus-8. At that time, clinicians treating these KS patients were routinely exposed to the pulmonary manifestations of this malignancy, including characteristic airway lesions, peribronchovascular opacities, and the typically hemorrhagic pleural effusions. They also witnessed uncommon complications of pulmonary KS such as chylous effusions, diffuse alveolar hemorrhage, and immune reconstitution inflammatory syndrome. Since the advent of highly active antiretroviral therapy, the incidence of KS has steadily declined and with that so has clinician familiarity with this disease. Herein, we present four KS cases recently encountered at our institution that illustrate both typical manifestations of pulmonary KS as well as its thoracic complications. The case descriptions are followed by a review of these clinical entities with the aim of restoring awareness among frontline physicians of what is now a rare but not quite extinct AIDS-defining neoplasm.

    Introduction Infective endocarditis is an infection of the endocardial lining of the heart mainly associated with congenital and rheumatic heart disease. Although it is a rare disease in children, it is associated with high morbidity and mortality; death due to infective endocarditis has been reported to be as high as 26% in sub-Saharan Africa. Methods This was a retrospective review of routinely collected data from patient records. Results A total of 40 children (71% female) with 41 episodes of infective endocarditis admitted to a general paediatric ward in Addis Ababa, Ethiopia between 2008 and 2013. Age ranged from 7 months to 14 years, with a median of 9 years (Inter quartile Range: 7-12 years). Rheumatic and congenital heart diseases were underlying risk factors in 49% and 51% of cases respectively. Congestive heart failure, systemic embolization and death occurred in 66%, 12% and 7.3% respectively. Death was associated with the occurrence of systemic embolization (P-value = 0.03). Conclusion Rheumatic heart disease was an important predisposing factor for infective endocarditis in Ethiopian children. Late presentations of cases were evidenced by high proportion of complications such as congestive heart failure. A low rate of clinically evident systemic embolization in this study may be a reflection of the diagnostic challenges. High proportion of prior antibiotic intake might explain the cause of significant BCNE. Preventive measures like primary and secondary prophylaxis of rheumatic fever may decrease the associated morbidity and mortality. Early detection and referral of cases, awareness creation about indiscriminate use of antimicrobials, and proper history taking and documentation of information recommended. PMID:26090033

    Objectives To study positive (PPV) and negative predictive value (NPV) of positron emission tomography with computed tomography (PET-CT) scans in determining malignancy in skull base lesions and perform a systematic literature review for optimal PET-CT interpretation. Design Retrospective case series and systematic literature review of the current English literature. Setting Tertiary referral academic medical center. Participants All patients with skull base lesions that underwent PET-CT and tissue biopsy from 2010 to 2013. Main Outcome Measures PPV and NPV of radiologist's report and standardized uptake value (SUV) cutoff of 2.5 and 3, biopsy with pathologic interpretation, clinical follow-up. Results A total of 31 PET-CT scans of 16 patients were studied; 10 PET-CT were performed upfront for diagnostic purposes and 21 were post-treatment surveillance scans. The PPV of radiologist's interpretation, SUV cutoff of 2.5, and SUV cutoff of 3.0 was 80%, 60%, and 68.4%, with a NPV of 100%, 83.3%, and 75%, respectively. Literature search yielded 500 abstracts; 7 studies met inclusion criteria for detailed review. No consensus or guidelines for optimal SUV cutoff value was found. Conclusions PET-CT based on SUV cutoff criteria alone has high NPV but low PPV in determining malignancy in skull base lesions. Interpretation by a radiologist experienced in nuclear medicine and neuroradiology, synthesizing clinical, SUV, and radiologic data are of superior value. PMID:26937333

    Background The purpose of this study was to examine factors associated with the implementation of case management (CM) interventions in primary health care (PHC) and to develop strategies to enhance its adoption by PHC practices. Methods This study was designed as a systematic mixed studies review (including quantitative and qualitative studies) with synthesis based on the diffusion of innovation model. A literature search was performed using MEDLINE, PsycInfo, EMBASE, and the Cochrane Database (1995 to August 2012) to identify quantitative (randomized controlled and nonrandomized) and qualitative studies describing the conditions limiting and facilitating successful CM implementation in PHC. The methodological quality of each included study was assessed using the validated Mixed Methods Appraisal Tool. Results Twenty-three studies (eleven quantitative and 12 qualitative) were included. The characteristics of CM that negatively influence implementation are low CM intensity (eg, infrequent follow-up), large caseload (more than 60 patients per full-time case manager), and approach, ie, reactive rather than proactive. Case managers need specific skills to perform their role (eg, good communication skills) and their responsibilities in PHC need to be clearly delineated. Conclusion Our systematic review supports a better understanding of factors that can explain inconsistent evidence with regard to the outcomes of dementia CM in PHC. Lastly, strategies are proposed to enhance implementation of dementia CM in PHC. PMID:24959072

    Policy Points: Co‐creation—collaborative knowledge generation by academics working alongside other stakeholders—is an increasingly popular approach to aligning research and service development.It has potential for “moving beyond the ivory towers” to deliver significant societal impact via dynamic, locally adaptive community‐academic partnerships.Principles of successful co‐creation include a systems perspective, a creative approach to research focused on improving human experience, and careful attention to governance and process.If these principles are not followed, co‐creation efforts may fail. Context Co‐creation—collaborative knowledge generation by academics working alongside other stakeholders—reflects a “Mode 2” relationship (knowledge production rather than knowledge translation) between universities and society. Co‐creation is widely believed to increase research impact. Methods We undertook a narrative review of different models of co‐creation relevant to community‐based health services. We contrasted their diverse disciplinary roots and highlighted their common philosophical assumptions, principles of success, and explanations for failures. We applied these to an empirical case study of a community‐based research‐service partnership led by the Centre of Research Excellence in Quality and Safety in Integrated Primary‐Secondary Care at the University of Queensland, Australia. Findings Co‐creation emerged independently in several fields, including business studies (“value co‐creation”), design science (“experience‐based co‐design”), computer science (“technology co‐design”), and community development (“participatory research”). These diverse models share some common features, which were also evident in the case study. Key success principles included (1) a systems perspective (assuming emergence, local adaptation, and nonlinearity); (2) the framing of research as a creative enterprise with human

    Clinical Scenario During routine staging work-up for a left breast mass, a 68-year-old woman complained of dysphagia and dysphonia. During further investigations, a left-sided lesion at the foramen magnum was observed on brain imaging. Both lesions were biopsied and showed a classical chordoma. Management The skull-base lesion and the breast lesion were surgically resected, and adjuvant radiotherapy was given. Summary Chordoma is a rare primary central nervous system tumour that seldom metastasizes. The lung is the most common site of metastasis. Synchronous breast metastasis from a skull-base chordoma is very rare, and a safe management option includes a maximum resection followed by adjuvant radiotherapy. PMID:27122985

    2015-03-01

    Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic, progressively fibrosing interstitial pneumonia that is associated with a significantly worse prognosis than other forms of chronic interstitial pneumonia. An early and accurate diagnosis of IPF is important to enable the initiation of disease-specific therapies, which have the potential to reduce disease progression, and the avoidance of inappropriate and potentially harmful drugs. Establishing an accurate diagnosis of IPF can be challenging. Recent studies and international guidelines advocate the importance of a multidisciplinary team (MDT) in the initial diagnostic assessment of patients with suspected IPF. Typical MDT members include a pulmonologist, a radiologist and a pathologist, with further input from a thoracic surgeon, a rheumatologist, a specialist nurse and an occupational physician where appropriate. Multidisciplinary diagnosis is considered the gold standard because it can improve the accuracy of diagnosis of IPF, avoid unnecessary testing (e.g. lung biopsy), and optimise patient management. Here we highlight the strengths and limitations of the multidisciplinary approach to IPF diagnosis through MDT discussion of two patient cases. PMID:25726558

    Stereotactic radiosurgery has long been recognized as the optimal form of management for high-grade arteriovenous malformations not amenable to surgical resection. Radiosurgical plans have generally relied upon the integration of stereotactic magnetic resonance angiography (MRA), standard contrast-enhanced magnetic resonance imaging (MRI), or computed tomography angiography (CTA) with biplane digital subtraction angiography (DSA). Current options are disadvantageous in that catheter-based biplane DSA is an invasive test associated with a small risk of complications and perhaps more importantly, the two-dimensional nature of DSA is an inherent limitation in creating radiosurgical contours. The necessity of multiple scans to create DSA contours for radiosurgical planning puts patients at increased risk. Furthermore, the inability to import two-dimensional plans into some radiosurgery programs, such as Cyberknife TPS, limits treatment options for patients. Defining the nidus itself is sometimes difficult in any of the traditional modalities as all draining veins and feeding arteries are included in the images. This sometimes necessitates targeting a larger volume, than strictly necessary, with stereotactic radiosurgery for treatment of the AVM. In this case report, we show the ability to use a less-invasive and three-dimensional form of angiography based on time-lapsed CTA (4D-CTA) rather than traditional DSA for radiosurgical planning. 4D-CTA may allow generation of a series of images, which can show the flow of contrast through the AVM. A review of these series may allow the surgeon to pick and use a volume set that best outlines the nidus with least interference from feeding arteries or draining veins. In addition, 4D-CTA scans can be uploaded into radiosurgery programs and allow three-dimensional targeting. This is the first reported case demonstrating the use of a 4D CTA and an MRI to delineate the AVM nidus for Gamma Knife radiosurgery, with complete

    2016-01-01

    Anti-tumor necrosis factor (TNFα) agents have acquired a prominent place in the treatment options for inflammatory disorders. Among the side effects of these agents are the so-called paradoxical reactions which have increasingly been reported in recent years. A review of literature was carried out using Medline (PubMed) database from January 2010 to December 2014 to collect all published articles on cases of anti-TNFα-induced psoriasis and psoriatic arthritis. Published articles were identified, reviewed and the relevant data extracted. A total of 22 studies (46 patients) fulfilled the inclusion criteria and were selected for analysis. Of the 46 patients, 45 (97.8%) developed psoriasis and 1 (2.1%) psoriatic arthritis. The mean age of patients was 47 years; three (6.5%) patients had a past history of psoriasis. Infliximab caused cutaneous reactions in the most number, 26 (56.5%) cases. Thirty seven (80.4%). patients developed primary plaque-type psoriasis. Women accounted for 86.9% of patients. There was complete resolution of psoriasis in 12 (26%) patients despite differences in the therapeutic approach. Cessation of the incriminated drug led to resolution of cutaneous lesions in 5 (10.8%), switching to another TNFα antagonist led to resolution in 6 (13%) and one (2.1%) patient improved despite continuation of the drug. As for the lone case of psoriatic arthritis, drug withdrawal did not result in improvement; only switching to another anti-TNFα agent helped. Since our sample was small, it was not adequately powered to draw any firm conclusions. However, in this analysis, we found that paradoxical reactions occurred predominantly in adult women, there were only isolated cases with a personal history of psoriasis, infliximab was responsible for most cases of these reactions and the most prevalent form was plaque-type psoriasis. The decision whether to continue or discontinue the triggering anti-TNFα agent should be individualized as results are highly variable

    Objectives Professional judgment is necessary to assess occupational exposure in population-based case-control studies; however, the assessments lack transparency and are time-consuming to perform. To improve transparency and efficiency, we systematically applied decision rules to the questionnaire responses to assess diesel exhaust exposure in the New England Bladder Cancer Study, a population-based case-control study. Methods 2,631 participants reported 14,983 jobs; 2,749 jobs were administered questionnaires (‘modules’) with diesel-relevant questions. We applied decision rules to assign exposure metrics based solely on the occupational history responses (OH estimates) and based on the module responses (module estimates); we combined the separate OH and module estimates (OH/module estimates). Each job was also reviewed one at a time to assign exposure (one-by-one review estimates). We evaluated the agreement between the OH, OH/module, and one-by-one review estimates. Results The proportion of exposed jobs was 20–25% for all jobs, depending on approach, and 54–60% for jobs with diesel-relevant modules. The OH/module and one-by-one review had moderately high agreement for all jobs (κw=0.68–0.81) and for jobs with diesel-relevant modules (κw=0.62–0.78) for the probability, intensity, and frequency metrics. For exposed subjects, the Spearman correlation statistic was 0.72 between the cumulative OH/module and one-by-one review estimates. Conclusions The agreement seen here may represent an upper level of agreement because the algorithm and one-by-one review estimates were not fully independent. This study shows that applying decision-based rules can reproduce a one-by-one review, increase transparency and efficiency, and provide a mechanism to replicate exposure decisions in other studies.

    Hypertrophic cranial pachymeningitis (HCP) is an uncommon disorder characterized by localized or diffuse thickening of the dura mater, and it usually presents with multiple cranial neurophaties. It has been associated with a variety of inflammatory, infectious, traumatic, toxic and neoplasic diseases, when no specific cause is found the process is called idiopathic. The infectious cases occur in patients under systemic immunosuppression, which have an evident contiguous source or those who have undergone neurosurgical procedures. We describe a case of a 62-year-old immunosuppressed woman with diabetes and rheumatoid arthritis, which had HCP and osteomyelitis of the skull base caused by pseudomonas aeruginosa, presenting with headache and diplopia. We believe this is the second documented case of pachymeningitis secondary to this microorganism. As a multifactorial disease, it is essencial to determine the specific causative agent of HCP before making treatment decisions, and great care is needed with immunocompromised patients.

    Introduction New-onset systemic lupus erythematosus (SLE) during pregnancy is rare and difficult to diagnose, especially in cases that manifest as preeclampsia. We report a patient with new-onset SLE that manifested as preeclampsia during pregnancy and provide a review of the literature to identify factors for a rapid diagnosis. Case A 32-year-old primigravid Japanese woman was diagnosed with severe preeclampsia and underwent emergent cesarean section at 29 weeks of gestation. Her hypertension and renal disorder gradually improved after the operation, but her thrombocytopenia and anemia worsened. SLE was diagnosed on postoperative day 5 by a comprehensive autoimmune workup. She was discharged on postoperative day 34 with remission. Conclusion Our case and previous reports suggest that distinguishing underlying SLE from preeclampsia in the third trimester is particularly difficult. Helpful factors for diagnosis of suspected SLE in these cases were persistence of symptoms and new atypical symptoms for preeclampsia revealed after delivery (e.g., fever, renal disorder, and thrombocytopenia).

    Testicular prostheses are regularly used in urological surgery and are important for postoperative psychological well-being in many patients undergoing orchiectomy. One of the recognised complications of this procedure is graft extrusion, which can result in significant morbidity for patients and require operative reintervention. Whilst most cases of extrusion involve upward graft migration to the external inguinal ring or direct displacement through the scrotal skin, we present an unusual case of complete expulsion of testicular implant three weeks postoperatively through a previously healthy scrotum. During surgical insertion of testicular prostheses, the urological surgeon must carefully consider the different surgical strategies at each step of the operation to prevent future extrusion of the graft. A stepwise review of the preventive surgical strategies to reduce the risk of graft extrusion encompasses the choice of optimal surgical incision, the technique of dissection to create the receiving anatomical pouch, the method of fixation of the implant within the receiving hemiscrotum, and the adoption of good postoperative care measures in line with the principles of sound scrotal surgery.

    2012-07-01

    Stress velopharyngeal incompetence (SVPI) is a special form of velopharyngeal incompetence observed in musicians who play wind and brass instruments. Due to high intraoral pressures generated while playing, the velopharyngeal structures fail to seal off the nasopharynx properly, resulting in unwanted nasal air leakage or noises. We present two young female professional clarinetists who experience symptoms of SVPI that preclude the development of their professional career. Both musicians underwent an inferior based pharyngeal flap, a well-known flap frequently used in cleft palate surgery. Both musicians were symptom-free after surgery and remain free of nasal noises while playing the clarinet after 2 and 4 years of follow-up. We present a review of literature of management of SVPI and show that the inferior-based pharyngeal flap is a feasible option for management of these potentially career ending symptoms.

    Video gaming injuries are classically regarded as eccentric accidents and novelty diagnoses. A case of an anterior cruciate ligament (ACL) tear sustained during Wii boxing spurned us to review the literature for other Wii-related injuries and Wii-based posttraumatic rehabilitation. The English literature listed in PubMed was systematically reviewed by searching for "Wii (trauma or injury or fracture)." Full-text articles were included after duplicate, blinded review. The type and treatment of injury as well as the Wii-based rehabilitation programs found were analyzed. Additionally, a new case of an acute ACL tear-sustained playing, Wii boxing, is additionally presented. After exclusion of irrelevant articles, 13 articles describing Wii-related injuries were included reporting on 3 fractures, 6 nonosseous, 2 overuse injuries, and 2 rehabilitation programs using Wii for posttraumatic rehabilitation. Among the presented Wii-related injuries, only 12.5% were treated conservatively, whereas 87.5% underwent either surgical or interventional treatment. Because of the reported case, the literature search was limited to Wii-related injuries excluding other video games. Another limitation of this article lies in the fact that mainly case reports but no controlled trials exist on the topic. Assumingly, primarily the more severe injuries are reported in the literature with an unknown number of possibly minor injuries. Motion-controlled video games, such as Wii, are becoming increasingly popular as a recreational entertainment. Because of their wide acceptance and entertaining nature, they are also increasingly recognized as a tool in rehabilitation. However, although the activity is simulated, injuries are real. Our systematic review shows that Wii gaming can lead to severe injuries, sometimes with lasting limitations. PMID:25816033

    We report a rare case of a 45-year-old African American woman with Neuroblastoma-like Schwannoma (Neurilemmoma) occurring in the posterior mediastinum as a pleural-based mass noted on computed tomography (CT) scan. A CT-guided core biopsy of the mass was performed and core biopsy imprints were prepared during the procedure. A Diff-Quik stain was performed for on-site evaluation of specimen adequacy. The hematoxylin and eosin (H&E) staining was evaluated subsequently. Immunohistochemistry panels were applied to the same specimen. The cytologic findings of the core biopsy imprints showed hypercellular smears with a predominance of small cells with atypical features including hyperchromatic, round nuclei and occasional nucleoli. Neurocytic rosettes were particularly appreciated on H&E stain. The immunohistochemical results exhibited strong and diffuse immunoreactivity for S-100 and vimentin. This case enriches the cytopathology literature by providing awareness of this tumor presenting as a posterior mediastinal mass. PMID:25940101

    Seizures can manifest with ictal swearing but few studies have investigated the localising value of this epileptic manifestation. In this case series and review of the literature, we attempted to determine whether ictal swearing could help localise the epileptic focus. We review two previously published cases and report eight additional epileptic patients with ictal swearing for whom the epileptic focus was determined based on clinical, structural, electrophysiological, and surgical outcome data. Results indicated that ictal swearing occurs more commonly in male subjects and lateralises to the non-dominant hemisphere, but has poor localisation value, arising either from the frontal, parietal, temporal or occipital lobes in different patients. We discuss the significance of these findings. [Published with video sequences]. PMID:24317202

    2014-08-01

    Endometrial scratching or injury was first suggested a decade ago as a simple intervention to improve endometrial receptivity in patients undergoing ART. More than a decade later, based on weak evidence some doctors have adopted this strategy, although there is not yet agreement about its real benefit. In this opinion paper, we analyze the methodological and plausibility problem beneath 'the Scratching Case'. This is also applicable to several other examples of spurious associations reported in the literature. In particular, we emphasize what should be done so as not to dilute evidence-based medicine by a vicious circle created by the over-exploitation of inadequate or insufficient data to compute incorrect or incomplete conclusions.

    The peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of aggressive neoplasms that account for <15% of all non-Hodgkin's lymphoma cases in adults. Angioimmunoblastic T-cell lymphoma (AITL) is a specific subtype of PTCL. The tumor is frequently aggressive and there is currently no general consensus regarding an effective treatment strategy. The present study reports a case in which bortezomib combined with dexamethasone was used to treat refractory AITL. A 63-year-old woman was admitted to Sir Run Run Shaw Hospital, Zhejiang University School of Medicine (Zhejiang, China) on August 17, 2013. The patient had been diagnosed with AITL for 4 months and had experienced a relapse of symptoms for the 4 days prior to admission. The patient demonstrated fever and dyspnea, accompanied by severe edema in the face and lower limbs, which later spread to the right upper limb. The patient was treated with bortezomib plus dexamethasone, which rapidly relieved the symptoms. The patient was subsequently administered an additional 2 cycles of bortezomib-based chemotherapy and survived for an additional 4 months, prior to succumbing to the disease. Only a small number of studies have reported the use of bortezomib in the treatment of T-cell lymphoma. The present study suggested that bortezomib-based treatment may be a reliable, safe and effective alternative for the treatment of relapsed/refractory PTCL. The efficacy of bortezomib as a treatment for PTCL requires additional evaluation in future studies. PMID:26998168

    Ossifying fibroma is a benign fibro-osseous tumour that rarely involves the ethmoid sinuses and orbit. It is classified as a benign fibroosseous lesion, a term that is synonymous with a variety of lesions reported in the literature. Recurrence rate with deleterious effects in cases of extramandibular ossifying fibroma is the impetus for open en bloc resection of the tumour. Continuously evolving techniques in endonasal endoscopic sinus surgery has rendered resection of large benign sinonasal and cephalonasal tumours possible. The authors report a case of ossifying fibroma involving the ethmoid sinus, orbit and anterior skull base in a 65-year-old previously healthy woman completely resected by endonasal endoscopic sinus surgery. The patient was free from postoperative complications and was dismissed from hospital on the sixth postoperative day. At present, the patient is disease-free at a regular five-year postoperative follow-up. Endonasal endoscopic resection of sinonasal ossifying fibromas is an excellent therapeutic option when performed by a surgeon experienced in endoscopic sinonasal surgery. The advantages of an endonasal endoscopic approach include direct visualization, enhanced visibility and magnification resulting in decreased intraoperative and postoperative morbidity. Aesthetic outcome is excellent in the absence of facial scars. PMID:27196080

    Reconstruction of total vulvectomy defect represents a challenge, and reconstructive methods include skin graft, local skin flap, musculocutanous flap, and pedicled perforator flap. We report a case of a 63-year-old patient affected by extramammary Paget's disease of vulva who underwent total vulvectomy receiving reconstruction with bilateral profunda artery perforator based V-Y rotation advancement flap. The literature about vulva reconstruction was reviewed. This innovative flap design combined the classic rotation flap and V-Y advancement flap with inclusion of the profunda artery perforators to augment the flap blood supply. Besides, the internal pudendal nerve was preserved to maintain the sensation of the neo-uvula. The flap survived completely without major post-operative complications with 9-months follow-up. Profunda artery perforator based V-Y rotation advancement flap may represent a valuable option in total vulvectomy defect reconstruction. PMID:26402576

    Folate-pathway gene polymorphisms have been implicated in several cancers and investigated inconclusively in relation to prostate cancer. We conducted a systematic review, which identified nine case-control studies (eight included, one excluded). We also included data from four genome-wide association studies and from a case-control study nested within the UK population-based Prostate Testing for Cancer and Treatment study. We investigated by meta-analysis the effects of eight polymorphisms: MTHFR C677T (rs1801133; 12 studies; 10,745 cases; 40,158 controls), MTHFR A1298C (rs1801131; 5 studies; 3,176 cases; 4,829 controls), MTR A2756G (rs1805087; 8 studies; 7,810 cases; 37,543 controls), MTRR A66G (rs1801394; 4 studies; 3,032 cases; 4,515 controls), MTHFD1 G1958A (rs2236225; 6 studies; 7,493 cases; 36,941 controls), SLC19A1/RFC1 G80A (rs1051266; 4 studies; 6,222 cases; 35,821 controls), SHMT1 C1420T (rs1979277; 2 studies; 2,689 cases; 4,110 controls), and FOLH1 T1561C (rs202676; 5 studies; 6,314 cases; 35,190 controls). The majority (10 of 13) of eligible studies had 100% Caucasian subjects; only one study had <90% Caucasian subjects. We found weak evidence of dominant effects of two alleles: MTR 2756A>G [random effects pooled odds ratio, 1.06 (1.00-1.12); P = 0.06 (P = 0.59 for heterogeneity across studies)] and SHMT1 1420C>T [random effects pooled odds ratio, 1.11 (1.00-1.22); P = 0.05 (P = 0.38 for heterogeneity across studies)]. We found no effect of MTHFR 677C>T or any of the other alleles in dominant, recessive or additive models, or in comparing a/a versus A/A homozygous. Neither did we find any difference in effects on advanced or localized cancers. Our meta-analysis suggests that known common folate-pathway single nucleotide polymorphisms do not have significant effects on susceptibility to prostate cancer. PMID:19706844

    2015-01-01

    Objective Treatment with an opioid agonist such as methadone or buprenorphine is the standard of care for opioid use disorder. Persons with opioid use disorder are frequently hospitalized, and may be undertreated due to provider misinformation regarding the legality of prescribing methadone for inpatients. Using a case-based review, this article aims to describe effective management of active opioid withdrawal and ongoing opioid use disorder using methadone or buprenorphine among acutely ill, hospitalized patients. Methods We reviewed pertinent medical and legal literature and consulted with national legal experts regarding methadone for opioid withdrawal and opioid maintenance therapy in hospitalized, general medical and surgical patients, and describe a real-life example of successful implementation of inpatient methadone for these purposes. Results Patients with opioid use disorders can be effectively and legally initiated on methadone maintenance therapy or buprenorphine during an inpatient hospitalization by clinical providers and successfully transitioned to an outpatient methadone maintenance or buprenorphine clinic after discharge for ongoing treatment. Conclusions Inpatient methadone or buprenorphine prescribing is safe and evidence-based, and can be used to effectively treat opioid withdrawal and also serves as a bridge to outpatient treatment of opioid use disorders.

Cytogenetic analysis of the peripheral blood lymphocytes revealed normal autosomes with 46X inv (Y) confirming the diagnosis of Turner's syndrome with Y cell line. Treatment was initiated with conjugated estrogen while recommending bilateral prophylactic oophorectomy to the patient. One year later the patient presented with abdominal mass, biopsy of the specimen following resection confirmed dysgerminoma originating from right ovary with no invasion or metastasis. The literature is reviewed with regard to the various pathogenetic mechanisms proposed for the development of germ cell tumors in ovary, the cytogenetic findings and recommendations to handle such scenario.

  2. Safely Combining Abdominoplasty with Aggressive Abdominal Liposuction Based on Perforator Vessels: Technique and a Review of 300 Consecutive Cases

    PubMed Central

    Smith, Lane F.

    2015-01-01

    Background: There continues to be controversy about performing abdominoplasty concurrently with abdominal liposuction. The concern is that liposuction on the already vascularly compromised abdominal flap will lead to increased complications and flap necrosis. The central abdomen is supplied by the epigastric system. If perforator vessels from this system are spared, the blood supply to the abdomen can be spared and liposuction should be able to be safely performed on the elevated abdominal flap. The purpose of this study was to evaluate the safety of abdominoplasty with concurrent abdominal liposuction when a perforator vessel is spared. Methods: A standard abdominoplasty was performed, sparing one or two perforator vessels from the deep superior epigastric artery system. A retrospective chart review of 300 consecutive patients who underwent abdominoplasty surgery combined with concurrent abdominal liposuction was performed. Complications, total volume of abdominal liposuction, and results were reviewed. Results: The overall complication rate was 17.3 percent (52 patients). Sixteen percent (48 patients) suffered minor complications and 1.3 percent (four patients) suffered major complications. Conclusions: Abdominoplasty can be combined safely with concurrent abdominal liposuction when a perforator vessel is spared. The combination of concurrent liposuction with abdominoplasty showed no increase in complication rates when a perforator vessel was spared. The perforator vessels are located consistently in a 2-cm radius located 4 cm from the midline and 6 cm from the subcostal margin. The potential advantages of abdominoplasty with concurrent liposuction include a better postoperative cosmetic result. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV. PMID:25919250

    The citrus peels and residue of fruit juices production are rich in d-limonene, a cyclic terpene characterized by antimicrobial activity, which could hamper energy valorization bioprocess. Considering that limonene is used in nutritional, pharmaceutical and cosmetic fields, citrus by-products processing appear to be a suitable feedstock either for high value product recovery or energy bio-processes. This waste stream, more than 10MTon at 2013 in European Union (AIJN, 2014), can be considered appealing, from the view point of conducting a key study on limonene recovery, as its content of about 1%w/w of high value-added molecule. Different processes are currently being studied to recover or remove limonene from citrus peel to both prevent pollution and energy resources recovery. The present review is aimed to highlight pros and contras of different approaches suggesting an energy sustainability criterion to select the most effective one for materials and energy valorization.

    Baslet, Gaston; Dworetzky, Barbara; Perez1, David L.; Oser, Megan

    2015-01-01

    Psychogenic non-epileptic seizures (PNES) were first described in the medical literature in the 19th century as seizure-like attacks not related to an identified central nervous system lesion and are currently classified as a conversion disorder, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). While a universally accepted and unifying etiological model does not yet exist, several risk factors have been identified. Management of PNES should be based on interdisciplinary collaboration, targeting modifiable risk factors. The first treatment phase in PNES is patient engagement, which is challenging given the demonstrated low rates of treatment retention. Acute interventions constitute the next phase in treatment and most research studies focus on short-term evidence-based interventions. Randomized controlled pilot trials support cognitive-behavioral therapy. Other psychotherapeutic and psychopharmacological interventions have been less well-studied using controlled and uncontrolled trials. Within the discussion of acute interventions, we present a preliminary evaluation for feasibility of a mindfulness-based psychotherapy protocol in a very small sample of PNES patients. We demonstrated in 6 subjects that this intervention is feasible in real-life clinical scenarios and warrants further investigation in larger scale studies. The final treatment phase is long-term follow-up. Long-term outcome studies in PNES show that a significant proportion of patients remain symptomatic and experience continued impairments in quality of life and functionality. We believe that PNES should be understood as a disease that requires different types of intervention during the various phases of treatment. PMID:25465435

    The aim of this study was to describe contextual events, abuse experiences, and disclosure processes of adolescents who presented to a hospital-based Child Advocacy Center for medical evaluation and evidentiary collection as indicated after experiencing multiple perpetrator rape during a single event (n = 32) and to compare these findings to a group of single perpetrator sexual assaults (n = 534). This study used a retrospective mixed-methods design with in-depth, forensic interviews and complete physical examinations of gang-raped adolescents. Patients ranged from 12 to 17 years (M = 14 years). Girls who experienced multiple perpetrator rape during a single event were more likely to have run away, to have drunk alcohol in the past month, and to have participated in binge drinking in the past 2 weeks. Acute presentation of these victims were rare but 30% had hymenal transections and 38% had sexually transmitted infections (STIs). Forensic interviews revealed alcohol was a common weapon used by offenders, and its use resulted in victims experiencing difficulty in remembering and reporting details for police investigation or physical and mental health care. Most victims were raped at parties they attended with people they thought they could trust, and they felt let down by witnesses who could have helped but did not intervene. Although relatively rare, multiple perpetrator rape during a single event is a type of severe sexual assault experience and has significant risks for deleterious health outcomes. These victims require health care by trained providers to diagnose physical findings, treat STIs, screen for trauma, and support victims. PMID:24933707

    Objectives The aim of this systematic review of randomised controlled trials (RCTs) and controlled trials (non-RCTs, NRCTs) is to investigate the effectiveness and related costs of case management (CM) for patients with heart failure (HF) predominantly based in the community in reducing unplanned readmissions and length of stay (LOS). Setting CM initiated either while as an inpatient, or on discharge from acute care hospitals, or in the community and then continuing on in the community. Participants Adults with a diagnosis of HF and resident in Organisation for Economic Co-operation and Development countries. Intervention CM based on nurse coordinated multicomponent care which is applicable to the primary care-based health systems. Primary and secondary outcomes Primary outcomes of interest were unplanned (re)admissions, LOS and any related cost data. Secondary outcomes were primary healthcare resources. Results 22 studies were included: 17 RCTs and 5 NRCTs. 17 studies described hospital-initiated CM (n=4794) and 5 described community-initiated CM of HF (n=3832). Hospital-initiated CM reduced readmissions (rate ratio 0.74 (95% CI 0.60 to 0.92), p=0.008) and LOS (mean difference −1.28 days (95% CI −2.04 to −0.52), p=0.001) in favour of CM compared with usual care. 9 trials described cost data of which 6 reported no difference between CM and usual care. There were 4 studies of community-initiated CM versus usual care (2 RCTs and 2 NRCTs) with only the 2 NRCTs showing a reduction in admissions. Conclusions Hospital-initiated CM can be successful in reducing unplanned hospital readmissions for HF and length of hospital stay for people with HF. 9 trials described cost data; no clear difference emerged between CM and usual care. There was limited evidence for community-initiated CM which suggested it does not reduce admission. PMID:27165648

    2012-01-01

    Purpose: Whole-brain radiation therapy (WBRT) is the standard of care after resection of a brain metastasis. However, concern regarding possible neurocognitive effects and the lack of survival benefit with this approach has led to the use of stereotactic radiosurgery (SRS) to the resection cavity in place of WBRT. We report our initial experience using an image-guided linear accelerator-based frameless stereotactic system and review the technical issues in applying this technique. Methods and Materials: We retrospectively reviewed the setup accuracy, treatment outcome, and patterns of failure of the first 18 consecutive cases treated at Brigham and Women's Hospital. The target volume was the resection cavity without a margin excluding the surgical track. Results: The median number of brain metastases per patient was 1 (range, 1-3). The median planning target volume was 3.49 mL. The median prescribed dose was 18 Gy (range, 15-18 Gy) with normalization ranging from 68% to 85%. In all cases, 99% of the planning target volume was covered by the prescribed dose. The median conformity index was 1.6 (range, 1.41-1.92). The SRS was delivered with submillimeter accuracy. At a median follow-up of 12.7 months, local control was achieved in 16/18 cavities treated. True local recurrence occurred in 2 patients. No marginal failures occurred. Distant recurrence occurred in 6/17 patients. Median time to any failure was 7.4 months. No Grade 3 or higher toxicity was recorded. A long interval between initial cancer diagnosis and the development of brain metastasis was the only factor that trended toward a significant association with the absence of recurrence (local or distant) (log-rank p = 0.097). Conclusions: Frameless stereotactic irradiation of the resection cavity after surgery for a brain metastasis is a safe and accurate technique that offers durable local control and defers the use of WBRT in select patients. This technique should be tested in larger prospective studies.

  9. Rhabdomyolysis in adolescent athletes: review of cases.

    2016-05-01

    Rhabdomyolysis is a syndrome characterized by muscle pain, weakness and myoglobinuria and ranges in severity from asymptomatic to life threatening with acute kidney failure. While a common condition in adult populations, it is understudied in pediatrics and the majority of adolescent cases are likely exercise-induced, caused by strenuous exercise in athletes. Recently, in our pediatric sports medicine practice, we have seen numerous cases of late adolescent high school athletes who present with severe muscle pain and were found to have elevated creatine kinase levels. The cases review potential contributing factors including characteristics of the workout, use of supplements, caffeine, medication, and metabolic or genetic predisposition. Treatment for exercised-induced rhabdomyolysis rarely requires more than rehydration. Return to play should be progressive, individualized, and include acclimatization and monitoring of hydration status, though guidelines require further review. PMID:27031535

  10. Examining End-of-Life Case Management: Systematic Review

    PubMed Central

    Thomas, Roger E.; Wilson, Donna M.; Birch, Stephen

    2014-01-01

    Case management was initiated in the 1970s to reduce care discontinuity. A literature review focused on end-of-life (EOL) case management identified 17 research articles, with content analysis revealing two themes: (a) seeking to determine or establish the value of EOL case management and (b) identifying ways to improve EOL case management. The evidence, although limited, suggests that EOL case management is helpful to dying individuals and their families. Research is needed to more clearly illustrate its usefulness or outcomes and the extent of need for it and actual availability. Among other benefits, EOL case management may help reduce hospital utilization, a major concern with the high cost of hospital-based care and the increased desire for home-based EOL care.

    Abstract Nocardia are Gram-positive filamentous bacteria responsible for infections ranging from opportunistic life-threatening disseminated diseases to chronic skin and soft-tissue infections. Even if virtually all organs can be infected, articular involvement is rare. Therefore, we report 3 recent cases and performed a literature review of cases of Nocardia arthritis in order to describe clinical features, therapeutic challenges, and outcome of these patients. Among 34 patients (31 in the literature plus our 3 cases), 21 (62%) were due to hematogenous dissemination, 9 (26%) were due to direct bacterial inoculation through the skin, and in 4 cases, the mechanism of infection was unknown. Four out of these 34 cases occurred on prosthetic joints. Whereas hematogenous infections mostly occurred in immunocompromised hosts (17 of 21, 81%), direct inoculation was mostly seen in immunocompetent patients. Eighty-two percent of patients (28 out of 34) received trimethoprim-sulfamethoxazole-containing regimens and median antibiotic treatment duration was 24 weeks (range, 12–120) for hematogenous infections and 12 weeks (range, 6–24) for direct inoculations. Outcome was favorable in 27 cases despite unsystematic surgical management (17 cases) without sequelae in 70% of the cases. Nocardia arthritis is rare but its management is complex and should rely on a combined approach with rheumatologist, infectious diseases expert, and surgeon. PMID:26496274

    2016-01-01

    Inducible urticaria is a heterogeneous group of skin disorders characterized by the appearance of wheals, pruritus and/or angioedema, sometimes accompanied by systemic symptoms caused by innocuous stimuli (cold, heat, pressure, etc.). This group of disorders compromises people's quality of life and most of the literature in this regard comes from case reports and case series since its epidemiology has been poorly studied and some cases are very rare. The aim of this review is to show an up-to-date overview of the available literature for various types of inducible urticarias, always beginning with an illustrative case and then describing their pathophysiological mechanisms, clinical manifestations, and treatment.

    Acremonium spp. cause human superficial infections including mycetoma, onychomycosis and keratitis. There are a few reports of systemic involvement in immunocompromised patients. However, isolated pulmonary infection in otherwise healthy hosts has never been reported in the literature.

    Objective. We report a rare case of keloidal scleroderma and provide an analysis of similar cases. Results. A 41 year-old woman presented with dark brown, indurated, exophytic nodules over the chest along with smaller hyperpigmented plaques scattered over the abdomen, with concomitant sclerodactyly. The clinical, laboratory, and pathological findings were consistent with a diagnosis of keloidal scleroderma. The patient was treated with methotrexate, resulting in reduced firmness of her plaques and no new lesions. A literature review of previously reported cases was performed using keywords including keloidal morphea, keloidal scleroderma, nodular morphea, and nodular scleroderma. In our review, the majority of patients were African American and female. 91% of cases had nodular lesions with distribution on the trunk. The majority of patients exhibited sclerodactyly and pulmonary involvement was reported in 28%1. The majority of patients were ANA positive (63%) and only 10% demonstrated anti-SCL-70 positivity. Conclusion. Keloidal scleroderma is a rare presentation, which can often be clinically confused with keloid and scar formation. Due to this being a rare variant, our knowledge of treatment options and efficacy is limited. Methotrexate could be considered as an initial treatment option for patients with progressive keloidal scleroderma. PMID:26697236

    2011-01-01

    A case of myofibrosarcoma of breast is reported. A female patient aged 81 years presented with a mammary mass lesion. Histologically, the tumor consisted of neoplastic spindle cells arranged in fascicles and with variably cellularity and hyalinization. Immunohistochemical studies showed expression of vimentin, smooth-muscle actin, and Bcl-2, but not desmin, S-100, C-kit, or CD34. Proliferative index identified by Ki67 was approximately 30%. Electron microscopy revealed variable amount of rough endoplasmic reticulum, myofilaments, fibronexus junctions, and fibronectin fibrils. The histological, immunohistochemical, and ultrastructural features of this tumor were consistent with myofibrosarcoma. This case will be one of the very few cases of ultrastructurally confirmed mammary myofibrosarcoma reported in the literature and contributes to the recognition of this rare mammary malignant neoplasm. The literature on mammary myofibrosarcoma and its differential diagnosis is also reviewed. PMID:21545434

    Non-invasive prenatal testing (NIPT) demonstrated a small chance for a false negative result. Since the “fetal” DNA in maternal blood originates from the cytotrophoblast of chorionic villi (CV), some false negative results will have a biological origin. Based on our experience with cytogenetic studies of CV, we tried to estimate this risk. 5967 CV samples of pregnancies at high risk for common aneuplodies were cytogenetically investigated in our centre between January 2000 and December 2011. All cases of fetal trisomy 13, 18 and 21 were retrospectively studied for the presence of a normal karyotype or mosaicism < 30% in short-term cultured (STC-) villi. 404 cases of trisomies 13, 18 and 21 were found amongst 5967 samples (6,8%). Of these 404 cases, 14 (3,7%) had a normal or low mosaic karyotype in STC-villi and therefore would potentially be missed with NIPT. It involved 2% (5/242) of all trisomy 21 cases and 7.3% (9/123) of all trisomy 18 cases. In 1:426 (14/5967) NIPT samples of patients at high risk for common aneuploidies, a trisomy 18 or 21 will potentially be missed due to the biological phenomenon of absence of the chromosome aberration in the cytotrophoblast.

    2014-01-01

    Transient quadriplegia is a rare injury that can change the course of an athlete’s career if misdiagnosed or managed inappropriately. The clinician should be well versed in the return-to-play criteria for this type of injury. Unfortunately, when an unknown preexisting syrinx is present in the athlete, there is less guidance on their ability to return to play. This case report and review of the current literature illustrates a National Collegiate Athletic Association (NCAA) Division I football player who suffered a transient quadriplegic event during a kickoff return that subsequently was found to have an incidental cervical syrinx on magnetic resonance imaging. The player was able to have a full neurologic recovery, but ultimately he was withheld from football. PMID:25177422

    Gebre-Giorgis, Abel A.; Roderique, Ensign Joseph D.; Stewart, Dane; Feldman, Michael J.; Pozez, Andrea L.

    2013-01-01

    Objective: Neostigmine is one of the treatment options for colonic pseudo-obstruction in the medical patient. However, experience in using neostigmine for this indication in burn patients has not been reported in the literature. We will present a case of a woman who developed colonic pseudo-obstruction during her hospital stay. When conservative management failed, neostigmine was administered with no adverse effects and resolution of the pseudo-obstruction. We will review the literature regarding the pathophysiology and treatment options for acute colonic pseudo-obstruction in burn patients. Methods: A 27-year-old woman with 35% total body surface area deep-partial and full-thickness flame burns. On hospital day 17, she developed a nonobstructive ileus. She failed conservative medical therapy. After consultation with colleagues in trauma surgery and a review of the literature (MeSH/PubMed/NLM), the decision was made to try neostigmine therapy rather than a surgical/procedural option such as colonoscopy. Results: The patient was moved to the intensive care unit and 2 mg of neostigmine was administered intravenously over 4 minutes. After 30 minutes, all abdominal examination findings had returned to baseline. No significant adverse effects were noted, and she did not redevelop abdominal distension afterward. Conclusion: This case report provides an alternative treatment modality in which neostigmine was used successfully in a burn patient after conservative medical treatment had failed. The authors believe that neostigmine may be a viable alternative to decompressive colonoscopy in burn patients for whom mechanical obstruction is properly excluded. PMID:23359843

    2014-01-01

    ABSTRACT Purpose: To identify case reports of statin-induced rhabdomyolysis and summarize common predisposing factors, symptoms, diagnostic findings, functional outcomes, characteristics, treatment, and rehabilitation. Method: MEDLINE, CINAHL, SCOPUS, and PEDro databases were searched (1990–2013) for relevant case reports using the search terms “Statins,” “Rhabdomyolysis,” “Myalgia,” “Muscle damage,” “Muscle injury,” and “Myopathy.” Relevance (based on title and abstract) was assessed by one investigator; two investigators independently reviewed the relevant articles to determine inclusion in the review. Results: A total of 112 cases met the inclusion criteria. The majority were in men (70%) and people over 45 years of age (mean 64 [SD 14] years). Simvastatin was the most commonly reported statin (n=55); the majority of cases reported the use of concomitant medications such as fibrates (n=25). Weakness (n=65) and muscle pain (n=64) were the most common symptoms. In 19 cases, the patient was referred to rehabilitation, but the case reports do not include descriptions of the treatment. Conclusion: Statin-induced rhabdomyolysis was more commonly reported when statins were used in conjunction with other drugs, which potentiated its effect. Research is needed to identify the role of exercise and rehabilitation following statin-induced rhabdomyoloysis since muscle damage may be severe and may have long-term effects on muscle function.

    Background The "applied" nature distinguishes applied sciences from theoretical sciences. To emphasize this distinction, we begin with a general, meta-level overview of the scientific endeavor. We introduce the knowledge spectrum and four interconnected modalities of knowledge. In addition to the traditional differentiation between implicit and explicit knowledge we outline the concepts of general and individual knowledge. We connect general knowledge with the "frame problem," a fundamental issue of artificial intelligence, and individual knowledge with another important paradigm of artificial intelligence, case-based reasoning, a method of individual knowledge processing that aims at solving new problems based on the solutions to similar past problems. We outline the fundamental differences between Medical Informatics and theoretical sciences and propose that Medical Informatics research should advance individual knowledge processing (case-based reasoning) and that natural language processing research is an important step towards this goal that may have ethical implications for patient-centered health medicine. Discussion We focus on fundamental aspects of decision-making, which connect human expertise with individual knowledge processing. We continue with a knowledge spectrum perspective on biomedical knowledge and conclude that case-based reasoning is the paradigm that can advance towards personalized healthcare and that can enable the education of patients and providers. We center the discussion on formal methods of knowledge representation around the frame problem. We propose a context-dependent view on the notion of "meaning" and advocate the need for case-based reasoning research and natural language processing. In the context of memory based knowledge processing, pattern recognition, comparison and analogy-making, we conclude that while humans seem to naturally support the case-based reasoning paradigm (memory of past experiences of problem-solving and

    2015-01-01

    Introduction: Tympanoplasty is indicated to restore hearing disability and prevent recurrent otorrhea. Materials and Methods: This study was a retrospective review of patients who underwent tympanoplasty with or without mastoidectomy over a 1-year period. Results: A total of 789 tympanoplasties were reviewed, with a male-to-female ratio of 1:1.1. In total, 91% and 9% of tympanoplasties were performed without and with mastoidectomy, respectively. Complete graft take was observed in 98.6% of cases. Approximately 25% of patients had an air-bone gap (ABG) gap ≤20dB pre-operatively, increasing to 75.6% post-operatively. ABG closure improved from 0.8% to 46.7%. Mean ABG improved from 26.30 ±8.1dB pre-operatively to 14 ± 10.41dB post- operatively (t=28.7, P<0.001). Generally, over 86% of patients had improvement in their hearing function post-operatively (mean= 12.5 ±9.5dB) (χ2= 104.2, P<0.001). Conclusion: Tympanoplasty is an effective procedure that can lead to improvement in hearing function in patients and prevention of recurrent ear discharge. Optimal results can be achieved through use of the appropriate surgical technique. PMID:25938081

    PubMed

    Bunawan, Nur C; Rastegar, Asghar; White, Kathleen P; Wang, Nancy E

    2014-01-01

    Djenkolism is an uncommon but important cause of acute kidney injury. It sporadically occurs after an ingestion of the djenkol bean (Archidendron pauciflorum), which is native to Southeast Asia. The clinical features defining djenkolism include: spasmodic suprapubic and/or flank pain; urinary obstruction; and acute kidney injury. The precise pathogenesis of acute kidney injury following djenkol ingestion remains unknown. However, it is proposed that an interaction between the characteristics of the ingested beans and the host factors causes hypersaturation of djenkolic acid crystals within the urinary system, resulting in subsequent obstructive nephropathy with sludge, stones, or possible spasms. We report a case of djenkolism from our rural clinic in Borneo, Indonesia. Our systematic literature review identified 96 reported cases of djenkolism. The majority of patients recovered with hydration, bicarbonate therapy, and pain medication. Three patients required surgical intervention; one patient required ureteral stenting for the obstructing djenkolic acid stones. Four of the 96 reported patients died from acute kidney failure. We stress the importance of awareness of djenkolism to guide medical practitioners in the treatment of this rare disease in resource-poor areas in Southeast Asia. PMID:24790471

    Emphysematous pyelonephritis is defined as the presence of gas-producing bacteria in the kidney and in peri-nephretic areas. Even if it is rare, the mortality rate of this affection is between 50% and 90%. The E. coli is responsible in 60% of the cases. We report a case of a 50 years old male patient, with under diagnosed diabetics, how is admitted with pains in the left flank, fever, troubled urine, hematuria and worsening of general state. The diagnostic of emphysematous pyelonephritis was confirmed by CT Scan. In spite of adapted antibiotherapy to the renal function, insulinotherapy and correction of hydro-electrolytic troubles, the patient died with septic shock associated to digestive bleeding. Based on this case and a review of the literature, the authors describe the different features of this disease. Only an urgent nephrectomy after a short reanimation can improve the prognostic.

    Arsenic poisonings occur in Mississippi despite public education campaigns to prevent poisonings in the home. We reviewed 44 Mississippi cases of arsenic exposures occurring from January 1986 to May 1990. We compared the epidemiologic differences between unintentional and intentional poisonings. Cases were found and characterized through the two toxicology laboratories and hospital records. Arsenic-based rodenticides were the arsenic source in 23 of the 44 exposures. Other sources were monosodium methylarsenate (4 cases), dodecyl ammonium methane arsonate (5 cases), and other compounds (12 cases). Of the 44 exposures, 27 were unintentional, 7 were suicide attempts, 6 were homicide attempts, and 4 were of unknown intent. Of the 27 unintentionally exposed patients, 19 were black and 14 were male; their median age was 3 years. Of the 13 intentionally poisoned persons, 9 were male and 10 were black, with a median age of 28 years. Six of the seven patients who attempted suicide were white; four of the six victims of attempted homicide were black. We recommend removal of remaining bottles of arsenic-based rodenticides from store shelves, and we urge practicing physicians to warn patients of the dangers of using such rodenticides.

    The present paper describes the development of reliability-based design criteria for oil and/or gas well casing/tubing. The approach is based on the fundamental principles of limit state design. Limit states for tubulars are discussed and specific techniques for the stochastic modeling of loading and resistance variables are described. Zonation methods and calibration techniques are developed which are geared specifically to the characteristic tubular design for both hydrocarbon drilling and production applications. The application of quantitative risk analysis to the development of risk-consistent design criteria is shown to be a major and necessary step forward in achieving more economic tubular design.

    Cockayne s syndrome is a genetic disorder with a recessive autosomal inheritance, described first by Cockayne in 1936. Patients with this syndrome present failure to thrive, short stature, premature aging, neurological alterations, photosensitivity, delayed eruption of the primary teeth, congenitally absent of some permanent teeth, partial macrodontia, atrophy of the alveolar process and caries. It could be caused by two gene mutations, CNK1 (ERCC8) and ERCC6, located on the 5 and 10 chromosomes respectively, causing two variations of Cockayne s syndrome, CS-A, secondary to a ERCC8 mutation and CS-B with ERCC6 mutation, the last one causes hypersensitivity to the ultraviolet light secondary to a DNA repair defect. The syndrome is also associated with mutations of the XPB, XPD and XPG genes. In this report we present a 9 year and 4 month old patient. He had a height of 94 cm, weight of 8.6 Kg, head circumference of 42 cm. and blood pressure of 120/80. Cachectic habitus, kyphosis, microcephaly, oval face, sunken eyes, a thin and beaklike nose, lack of subcutaneous facial fat (especially in the middle of the face), and large ears give the patient a birdlike appearance. It is notorious the photosensitivity in all the sun-exposed skin. The patient also displays delayed psychomotor skills and mental retardation. In the oral cavity we found deficient hygiene, gingivitis, cervical caries, enamel hipoplasia, abnormal position of the upper and inferior lateral incisors, macrodontia of the upper central teeth, the left one presented a caries. In the x-ray we observed congenital absence of 14, 23 and 24 teeth and mandibular hipoplasia. The aim of this review is to show the dentistry community the characteristics of the Cockayne s syndrome by means of a clinical case. PMID:16648759

    This study uses current epidemiological data to evaluate whether phytoestrogen intake is associated with a reduced risk of prostate cancer. We performed a random-effect meta-analysis of published data retrieved from PubMed, Web of Science, ProQuest, and CNKI, which was supplemented by a manual search of relevant references. Study quality was assessed using the Newcastle-Ottawa Scale (NOS). Subgroup analysis and meta-regression were performed to explore the source of heterogeneity. Sensitivity analysis was evaluated to assess the stability of the results. Egger's test and funnel plots were used to detect the existence of publication bias. We retrieved 507 papers, and 29 studies were ultimately confirmed as eligible. The meta-analysis showed that phytoestrogen intake was significantly associated with a reduced risk of prostate cancer, with an odds ratio (OR) of 0.77 (95% CI 0.66-0.88; I(2)  = 77.6%). The food/nutritional sources that were significantly associated with a reduced risk of prostate cancer included soy and soy products, tofu, legumes, daidzein, and genistein. Subgroup analysis indicated that the associations were significant among Asians and Caucasians, but not among Africans. Meta-regression revealed that the pooled OR increased with the number of cases in the studies. The results might be affected by publication bias based on the Eggers' test (p = 0.011) and the asymmetry of the funnel plot. Phytoestrogen intake may reduce the risk of prostate cancer in Asians and Caucasians. Regular intake of food that is rich in phytoestrogens, such as soy/soy products or legumes, should be recommended. PMID:27260185

  3. A Classification-based Review Recommender

    NASA Astrophysics Data System (ADS)

    O'Mahony, Michael P.; Smyth, Barry

    Many online stores encourage their users to submit product/service reviews in order to guide future purchasing decisions. These reviews are often listed alongside product recommendations but, to date, limited attention has been paid as to how best to present these reviews to the end-user. In this paper, we describe a supervised classification approach that is designed to identify and recommend the most helpful product reviews. Using the TripAdvisor service as a case study, we compare the performance of several classification techniques using a range of features derived from hotel reviews. We then describe how these classifiers can be used as the basis for a practical recommender that automatically suggests the mosthelpful contrasting reviews to end-users. We present an empirical evaluation which shows that our approach achieves a statistically significant improvement over alternative review ranking schemes.

    1992-01-01

    Tuberculous infection of the oesophagus is rare. This is confirmed by our present review of cases managed in our teaching hospitals over a period of 18 years which uncovered only 11 patients. The main presentation is that of dysphagia whose algorithm of investigation should seek to differentiate tuberculosis from carcinoma, the more common cause of this symptom. Of the 11 patients, 9 presented with dysphagia while 2 had haemorrhage; 7 had an abnormal plain chest radiograph, of whom 4 had a mediastinal mass lesion (3 were lymphadenopathy and one an abscess). All but one had an abnormal radio-contrast oesophagogram, including a mediastinal sinus in two and a traction diverticulum in another two. The mainstay of investigation was oesophagoscopy through which diagnostic biopsy material was obtained in half of the patients. In the other half diagnosis was by either biopsy of associated mediastinal (3) or cervical (1) lymph node masses or by acid fast bacilli positive sputum (1). The diagnosis was established post-mortem in one patient. Treatment was primarily non-operative with standard anti-tuberculosis drug therapy. Two patients underwent a diagnostic thoracotomy and one a drainage of mediastinal abscess together with resection and repair of oesophago-mediastinal sinus during the early part of the series. Outcome of management was very rewarding in 9 patients and death occurred in 2 patients, one of whom had his anti-tuberculosis drug therapy interrupted by severe hepatitis B virus infection. The other death occurred in a patient whose haemorrhage from an aorta-oesophageal fistula was not established ante-mortem. It is recommended that when biopsy material of the oesophagus is unobtainable or non-diagnostic in patients with dysphagia, especially with an abnormal chest radiograph or human immunodeficiency virus infection, effort should be made to obtain biopsy material from associated lymph nodes, even by thoracotomy if necessary, or culture of biopsy from the

  5. Review of extended producer responsibility: A case study approach.

    2015-07-01

    Principles of extended producer responsibility have been the core of most of the recent policies and legislation dealing with the end-of-life management of recyclable goods. This article makes an exploratory review of 27 cases of extended producer responsibility from developed and developing economies with and without informal recycling, to ascertain the most important aspect of extended producer responsibility. A comparative analysis of the cases with respect to role of stakeholders in the upstream and downstream stages of the extended producer responsibility has been carried out. Further, the study uses exploratory factor analysis to determine the important aspects of the extended producer responsibility in practice using 13 variables identified from the review. Findings of the comparative analysis reveal that financial responsibility of the producers and separate collecting and recycling agencies contributed significantly to the success of the extended producer responsibility-based environmental policies. Regulatory provisions, take-back responsibility and financial flow come out to be the three most important aspects of the extended producer responsibility. Presence of informal sector had a negative impact on the regulatory provisions. The outcomes of this study could serve as a guideline for designing of effective extended producer responsibility-based policies. PMID:26185163

    2014-12-01

    Laryngomalacia is a dynamic airway condition characterised by inward collapse of flaccid supraglottic structures during inspiration. Although the most common cause of stridor in the paediatric population, adult-onset laryngomalacia remains a rare entity and its management, challenging. Two cases of adult-onset laryngomalacia are reported. A review of the English literature is performed and additional publications identified by hand-searching relevant papers; 13 case reports/series comprising 28 cases of adult-onset laryngomalacia were identified, divided into two main groups: idiopathic (6/28) and acquired (22/28). The aetiology of the acquired form includes neurological, traumatic and iatrogenic. Reported therapeutic measures used are laser supraglottoplasty, epiglottopexy, partial epiglottidectomy, defunctioning tracheostomy and intubation whilst correcting the underlying cause. The majority of patients only required one therapeutic procedure (follow-up of 2-24 months). A strong index of suspicion is required to diagnose adult-onset laryngomalacia aided by in-office laryngoscopy. The rarity of this condition prevents management-based randomised controlled trials.

    Introduction Denture ingestion or aspiration is a problem requiring awareness of different specialists including dentists, surgeons, otolaryngologists, anesthesiologists etc. in terms of prevention, early diagnosis and adequate treatment. Complications of swallowed dentures include hollow viscus necrosis, perforation, penetration to neighbor organs leading to fistulae, bleeding and obstruction. Presentation of cases First case is a 54-year-old female who accidentally swallowed retractable one-tooth denture during fall about 22 h before admission and clinical manifestation of acute small bowel obstruction developed. The patient underwent laparotomy, enterotomy with retrieval of the foreign body. The second case is a 31-year-old male who accidentally ingested fixed one-tooth prosthesis while eating which impacted in the ileocaecal valve. During the preparation to colonoscopy the denture spontaneously passed out with stools. Discussion Denture ingestion is more common among patients with psychoneurologic deficit, alcohol and drug abusers. Among healthy and younger population denture ingestion is rare. Both reported patients are not elder. Thus dislodgement of removable or fixed dentures is another risk factor of denture ingestion. Most common site of denture impaction is esophagus; small bowel impaction is rare. Moreover, in most reported cases, small bowel impaction of ingested dentures leads to small bowel perforation. In our first case the complication of denture ingestion appeared to be bowel obstruction what is even rarer. Conclusion Fixed dentures can be accidentally ingested as well as removable dentures. Denture loosening leads to accidental denture ingestion. Patients with denture loosening should be recommended to visit dentist as soon as possible. PMID:26635957

    Introduction Mucoceles are benign expansive cystic formations, composed of a mucus-secreting epithelium (respiratory or pseudostratified epithelium). Nasolacrimal mucocele occurs in a small proportion of children with nasolacrimal duct obstruction and is characterized by a cystic mass in the medial canthus with dilation of the nasolacrimal duct; although dacryocystoceles are rare in adults, they have been reported in patients with trachoma. Objective Discuss clinical aspects, diagnosis, and therapeutic management of mucocele of nasolacrimal duct based on literature review. Resumed Report The authors report a case of bilateral congenital nasolacrimal duct cysts in a 30-year-old man, identified as a tumor in the topography of both lacrimal sacs since birth without associated symptoms. The patient underwent successive surgical treatments, leading to recurrence of the tumor at the right side and recurrent local infections. Conclusion Endoscopic dacryocystorhinostomy has been increasingly used with good results and success rates similar to the external access. PMID:25992160

  20. Autoscopic phenomena: case report and review of literature

    PubMed Central

    2011-01-01

    Background Autoscopic phenomena are psychic illusory visual experiences consisting of the perception of the image of one's own body or face within space, either from an internal point of view, as in a mirror or from an external point of view. Descriptions based on phenomenological criteria distinguish six types of autoscopic experiences: autoscopic hallucination, he-autoscopy or heautoscopic proper, feeling of a presence, out of body experience, negative and inner forms of autoscopy. Methods and results We report a case of a patient with he-autoscopic seizures. EEG recordings during the autoscopic experience showed a right parietal epileptic focus. This finding confirms the involvement of the temporo-parietal junction in the abnormal body perception during autoscopic phenomena. We discuss and review previous literature on the topic, as different localization of cortical areas are reported suggesting that out of body experience is generated in the right hemisphere while he-autoscopy involves left hemisphere structures.

    Multiple myeloma (MM) is a plasma cell disorder associated with clonal proliferation of plasma cells. Nonsecretory multiple myeloma (NSMM) is a rare variant of MM and accounts for approximately 1% to 5% of all cases. It is defined as symptomatic myeloma without detectable monoclonal immunoglobulin on serum or urine electrophoresis. This variant usually poses a diagnostic challenge to the clinician. We present a 60-year-old Nigerian man who was investigated extensively for bone pain, weight loss, and anaemia. He was eventually diagnosed as having nonsecretory multiple myeloma based on histology and immunohistochemistry results of bone marrow trephine biopsy. He is currently being managed with bortezomib, doxorubicin, and thalidomide, as well as zoledronic acid. He is also on anticoagulation. He continues to show remarkable clinical improvement. We describe this case report and literature review for better awareness amongst medical practitioners and pathologists. PMID:26649043

    Mycosis fungoides (MF), also known as Alibert-Bazin syndrome or granuloma fungoides, is the most common form of cutaneous T-cell lymphoma. Cutaneous lymphomas are an uncommon, heterogeneous group of non-Hodgkin lymphomas (NHLs) of T- and B-cell origin where the skin is the primary organ of involvement. This is a case of a 60-year-old Nigerian woman, who was diagnosed and managed as a case of chronic dermatitis but further investigations confirmed a diagnosis of MF; she was thereafter managed with topical glucocorticoids/chemotherapy and improved on these treatments.

    Melioidosis is a bacterial infection caused by Burkholderia pseudomallei, a gram-negative saprophytic bacillus. Cases occur sporadically in the Americas with an increasing number of cases observed among people with no travel history to endemic countries. To better understand the incidence of the disease in the Americas, we reviewed the literature, including unpublished cases reported to the Centers for Disease Control and Prevention. Of 120 identified human cases, occurring between 1947 and June 2015, 95 cases (79%) were likely acquired in the Americas; the mortality rate was 39%. Burkholderia pseudomallei appears to be widespread in South, Central, and North America. PMID:26458779

    Pylephlebitis, or suppurative thrombophlebitis of the portal mesenteric venous system occurring in the setting of abdominal inflammatory processes, is a rare but deadly disease commonly associated with diverticulitis. We review our institutional experience in the management of patients with this condition. A retrospective review of medical records from 2002 to 2012 was performed. Patients with a portal mesenteric vein thrombosis (PMVT) within 30 days of an intra-abdominal inflammatory process were identified and evaluated. Ninety-five patients were included. The mean patient age at presentation was 57 years (range, 24–88). The most common associated processes were pancreatitis (31 %), followed by diverticulitis (19 %). Bacteremia was noted in 34 (44 %) patients. The most common organism cultured was Streptococcus viridans. Antibiotic and anticoagulation therapy was given in 86 (91 %) and 78 (82 %) patients, respectively. Overall, we report an 11 % mortality rate. Albeit rare, pylephlebitis most commonly was manifested in the setting of pancreatitis. Treatment should be individualized to culture results and extent of thrombosis. If diagnosed early and managed appropriately, a favorable outcome is possible. PMID:26160320

We report a case of an intracerebral fibroma without dural or leptomeningeal attachment, discuss the pertinent diagnostic findings and briefly review all prior reports of this entity. PMID:27194681

    Granuloma annulare (GA) is a granulomatous dermatosis that rarely presents on the face and is extremely uncommon in the periocular region. We report our experience with the presentation and management of GA lesions on the eyelids of a 17-year-old girl. We performed a review of published literature and identified 13 cases of pediatric periocular GA. One additional case was identified upon review of all pediatric GA cases at the Cleveland Clinic Foundation. Review of these cases suggests that periocular GA is a benign condition that spontaneously regresses within a few months. GA nodules have a predilection for the upper eyelids. A greater incidence is noted in African American children. Awareness of the self-resolving nature of this condition can prevent unnecessary surgical excisions in affected children. PMID:23551387

  14. Treatment of Klebsiella Pneumoniae Carbapenemase (KPC) infections: a review of published case series and case reports

    2012-01-01

    The emergence of Klebsiella pneumoniae carbapenemases (KPCs) producing bacteria has become a significant global public health challenge while the optimal treatment remains undefined. We performed a systematic review of published studies and reports of treatment outcomes of KPC infections using MEDLINE (2001–2011). Articles or cases were excluded if one of the following was fulfilled: no individual patient data provided, no treatment regimen specified, no treatment outcome specified, report of colonization, or greater than three antibiotics were used to treat the KPC infection. Data extracted included patient demographics, site of infection, organism, KPC subtype, antimicrobial therapy directed at KPC-infection, and treatment outcome. Statistical analysis was performed in an exploratory manner. A total of 38 articles comprising 105 cases were included in the analysis. The majority of infections were due to K. pneumoniae (89%). The most common site of infection was blood (52%), followed by respiratory (30%), and urine (10%). Forty-nine (47%) cases received monotherapy and 56 (53%) cases received combination therapy directed at the KPC-infection. Significantly more treatment failures were seen in cases that received monotherapy compared to cases who received combination therapy (49% vs 25%; p= 0.01). Respiratory infections were associated with higher rates of treatment failure with monotherapy compared to combination therapy (67% vs 29% p= 0.03). Polymyxin monotherapy was associated with higher treatment failure rates compared to polymyxin-based combination therapy (73% vs 29%; p= 0.02); similarly, higher treatment failure rates were seen with carbapenem monotherapy compared to carbapenem-based combination therapy (60% vs 26%; p= 0.03). Overall treatment failure rates were not significantly different in the three most common antibiotic-class combinations: polymyxin plus carbapenem, polymyxin plus tigecycline, polymyxin plus aminoglycoside (30%, 29%, and 25

    The management of multidrug-resistant human immunodeficiency virus (MDR HIV) infections in children is particularly challenging due to the lack of experience with new drugs. Dolutegravir, combined with an optimized antiretroviral background therapy, is promising for the treatment of MDR HIV and has been approved recently for adults and adolescents. Data for children are extremely limited. We describe the efficacy, safety and plasmatic levels of a dolutegravir-based, complex active antiretroviral treatment regimen in a severely overweight 11-year-old child infected with an MDR HIV strain.

    A contaminated contact lens case can act as a reservoir for microorganisms that could potentially compromise contact lens wear and lead to sight threatening adverse events. The rate, level and profile of microbial contamination in lens cases, compliance and other risk factors associated with lens case contamination, and the challenges currently faced in this field are discussed. The rate of lens case contamination is commonly over 50%. Coagulase-negative Staphylococcus, Bacillus spp., Pseudomonas aeruginosa and Serratia marcescens are frequently recovered from lens cases. In addition, we provide suggestions regarding how to clean contact lens cases and improve lens wearers' compliance as well as future lens case design for reducing lens case contamination. This review highlights the challenges in reducing the level of microbial contamination which require an industry wide approach. PMID:25980811

    Sparganosis is a severe parasitic infection caused by the larvae of Spirometra mansoni, also called "sparganum." In human hosts, the Spirometra mansoni larva commonly targets the subcutaneous tissue or muscle. Sometimes it can also migrate into the brain, resulting in cerebral sparganosis, mainly characterized by focal neurological symptoms such as seizures and radiological "wandering lesions" on magnetic resonance images (MRIs). Clinical cases of cerebral sparganosis have been reported worldwide, mainly in Asian countries, but also in North America, South America and Australia. Only two cases have been previously reported in Europe. A 29-year-old male from Bolivia, who lived in Spain, presented to our service for seizures and a multicystic brain lesion, initially suspected to be a dysembryoplastic neuroepithelial tumor (DNET). He underwent gross total resection of the mixed solid/cystic lesion. Pathology revealed gliosis, multiple interconnected cystic cavities with fibrous walls, inflammatory cell infiltration and no necrotizing granulomatous reaction. Inside the cavities, a parasitic form was identified as the larva of the cestode Spirometra mansoni. At 1-year follow-up, the patient had no deficits and was seizure free. Clinicians should be alerted to the possible existence of this rare entity in Europe, especially in patients from endemic areas with a possible infection history as well as "wandering lesions" on the MRI.

    We present a 9-year-old boy with history of perinatal asphyxia and neonatal seizures; who presented with delayed development of speech, with predominant dysarthria, dysphagia, and drooling of saliva and unable to protrude tongue along with delayed motor and mental milestones. He had complex partial seizures since last 3 years requiring multiple anti-epileptic drugs. He had dysarthria, nasal twang, and drooling of saliva with difficulty in chewing and swallowing. Hearing and understanding were normal. Bilateral trigemino-facio-linguo-pharyngeal palsy was noticed on voluntary movements with normal jaw jerk with preserved automatic and emotional motor movements. Electroencephalography revealed focal left fronto-temporal epileptiform discharges and brain imaging was suggestive of bilateral cortical and subcortical region encephalomalacia, predominantly involving bilateral opercular region. The clinical and neuroimaging features correspond to bilateral opercular syndrome which could have resulted from the perinatal insult in this case. PMID:24082930

    Diagnosis of myocardial infarction or acute coronary syndrome is difficult, especially in atypical presentation at an emergency department, and sometimes results in serious legal issues. Symptoms of atypical presentation include shortness of breath, dyspnoea on exertion, toothache, abdominal pain, back pain and throat pain. As of now, reports of a headache, especially exertional headache, as the only presentation of acute cardiac ischaemia are rare and only have case reports. We present two patients with a cardiac source of headache and analyse 32 patients with similar situations from MEDLINE search from 1966 to the present. Cardiac cephalalgia is benign in general, but potential risks for death should be considered. If the patient has increased risk of atherosclerosis with exertional headache, anginal headache should be highly suspected and further work-up should be undertaken. PMID:18505457

    Botulism is a rare disease in Chile and of the known clinical presentation, infant botulism is the most common. We report the case of a previously healthy seven month old male infant with a two weeks history of rinorrea, cough, fatigue, constipation and progressive weakness after the consumption of honey. Stool cultures were positive for Clostridium botulinum group 1 type A and electromyography was compatible with the diagnosis. The patient evolved with arterial hypertension, interpreted as secondary to autonomic dysfunction, which responded to calcium channel blockers. Muscle tone improved progressively during the following four weeks. Infant botulism is a potentially fatal disease; diagnosis can be difficult given the broad clinical manifestations. Prevention should focus on education of parents of infants as well as medical personnel. PMID:19621149

    Although originally considered to be uncommon, Takotsubo cardiomyopathy is becoming increasingly visible, annually comprising an increasing portion of suspected diagnoses of acute coronary syndrome. This condition is characterized by reversible left ventricular akinesis without significant coronary artery obstruction. This case study presents five patients diagnosed with Takotsubo cardiomyopathy, as confirmed by echocardiogram and angiography. All of the patients presented with classic myocardial chest pain and elevated troponins. Following diagnosis, they were treated with supportive measures, particularly angiotensin-converting enzyme inhibitors, and beta-blockers. All patients made a full recovery. Though the mechanism of Takotsubo has not been fully elucidated, hypotheses suggest it may be related to excessive catecholamine levels causing either myocardial stunning or coronary vasospasm. Recognition and understanding of this unusual pathology are essential because it can lead to improved clinical management.

    There is limited literature available on the comorbidity between autism spectrum disorder (ASD) and substance use disorder (SUD). This paper reviews existing literature and exemplifies the challenges of treating this population with a case report of an adult male with ASD and DSM-5 alcohol use disorder. This review and case study seeks to illustrate risk factors which predispose individuals with ASD to developing SUD and discuss the obstacles to and modifications of evidence-based treatments for SUD. A review of the therapeutic interventions implemented in the treatment of this young male are described to highlight potential recommendations for the general management of SUD in those with ASD.

    Sarcoidosis involving the gastrointestinal tract is extremely rare. Clinically recognizable gastrointestinal system involvement occurs in 0.1% to 0.9% of patients with sarcoidosis. We encountered a 22-year-old African American female admitted to Johns Hopkins Hospital (Baltimore, Maryland) for a 2-week history of fever, chills, eye pain, and abdominal pain. Her abdominal CT scan showed multiple subcentimeter retroperitoneal lymph nodes. An upper endoscopy was performed and discovered an antral nodule that measured about 7 mm and antral gastritis in which biopsies showed active chronic necrotizing granulomatous gastritis. Biopsies of the antral polyp showed focal intestinal metaplasia and active chronic necrotizing granulomatous pattern. Stains for Helicobacter pylori, acid fast, and fungi were negative. A small-bowel series showed no abnormality. Ophthalmologic evaluation revealed panuveitis with bilateral optic disc edema. The patient was later prescribed 60 mg of prednisone by mouth once a day and subsequently her abdominal pain and fever resolved during follow-up 2 months later. This literature review demonstrates the importance in the diagnosis, pathophysiology, clinical manifestations, types of gastric sarcoidosis, major endoscopic findings, and management of gastric sarcoidosis.

    Pemphigus vulgaris (PV) is an autoimmune disease accounting for 80% of all cases of pemphigus. Before the advent of corticosteroid therapy, pemphigus was fatal, with a mortality rate of up to 75% in the first year. It is still a serious disorder, but the 5% to 10% mortality rate is now primarily due to the side effects of therapy. In 75% to 80% of cases, PV lesions first appear in the oral cavity. Dentists are therefore in a unique position to recognize the oral manifestations of the disease, allowing early diagnosis and initiation of treatment. The diagnosis is based on pathological examination and immunofluorescence testing. Systemic corticosteriods and steroid-sparing agents are the mainstays of treatment; topical corticosteroids may also be used to accelerate healing of persistent oral lesions. This article describes a 71-year-old woman with multiple chronic ulcers in the oral cavity, in whom PV was diagnosed 4 months after the symptoms first appeared. The article also reviews the current literature on diagnosis and treatment of the condition. PMID:16271165

    2016-06-01

    Sixteen cases of cloacal prolapse in raptors were reviewed in this study. Colonic prolapse was the most common presentation (56% of cases). Red-tailed hawks ( Buteo jamaicensis ) were overrepresented, comprising 66% of colonic prolapse cases. In cases of colonic prolapse, postsurgical stricture formation was a commonly identified complication after resection and anastomosis of the colon. A novel technique was used in 2 cases of colonic prolapse, in which sterile, semirigid rubber tubing was placed in the distal colon and removed per-cloaca at the end of the procedure; this facilitated a secure, fluid-tight anastomosis while maintaining sufficient intestinal lumen. Oviductal prolapse (31% of cases) was associated with the most guarded prognosis (40% treatment success). Cloacoliths were treated successfully in 2 birds (13% of cases) by minimally invasive per-cloacal manual removal. PMID:27315380

    The clinical case report is a popular genre in medical writing. While authors and editors have debated the justification for the clinical case report, few have attempted to examine the long history of this genre in medical literature. By reviewing selected literature and presenting and discussing excerpts of clinical case reports from Egyptian antiquity to the 20th century, we illustrate the presence of the genre in medical science and how its form developed. Central features of the clinical case report in different time periods are discussed, including its main components, structure, style and author presence. PMID:25057387

    2014-01-01

    Chorea rarely complicates ischemic or hemorrhagic cerebral vascular lesions. Clinical symptoms usually involve one side of the body while the injury is situated on the contralateral cerebral hemisphere. Spontaneous remission is the norm, but sometimes symptomatic treatment is required. A 58-year-old male patient who suffers from untreated high blood pressure, type II obesity, smokes 6 packs of cigarettes per year and has a moderate intake of alcohol is presented. The patient’'s recent history began three days before he appeared at the Emergency Department. His symptoms were ceaseless, involuntary movements in his left arm and foot during day and night with no restriction of voluntary movements. Physical examination and laboratory tests revealed no other findings. Magnetic resonance imaging of the brain showed hyperintensity in the right posterolateral thalamic region consistent with ischemic cerebrovascular disease. Symptomatic therapy was indicated and his underlying conditions were addressed. The importance of this case lies on the low prevalence as well as the scarcity of publications regarding vascular causes of hemichorea, including diagnosis, therapy and prognosis. PMID:25473878

    Gingival fibromatosis (GF) is a condition characterized by a progressive, normal colored enlargement of the gingiva caused by an increase in the size of submucosal connective tissue. Both familial and idiopathic variants of the condition exist. The authors present a case report of a 38-year-old African American man who presented with an impressive overgrowth of the maxillary and mandibular gingivae, subsequently diagnosed as idiopathic GF. In this report, the authors will review the etiologies, treatment, and clinical and histological findings of GF, review similar cases found in the literature, and discuss the differential diagnosis for diffuse gingival enlargements.

    Internet-based science learning has been advocated by many science educators for more than a decade. This review examines relevant research on this topic. Sixty-five papers are included in the review. The review consists of the following two major categories: (1) the role of demographics and learners' characteristics in Internet-based science learning, such as demographic background, prior knowledge, and self-efficacy; and (2) the learning outcomes derived from Internet-based science learning, such as attitude, motivation, conceptual understanding, and conceptual change. Some important conclusions are drawn from the review. For example, Internet-based science learning is equally favorable, or in some cases more so, to learning for female students compared to male students. The learner's control is essential for enhancing students' attitudes and motivation toward learning in Internet-based science learning environments. Nevertheless, appropriate guidance from teachers, moderators, or the Internet-based learning environment itself is still quite crucial in Internet-based science learning. Recommendations for future research related to the effects of Internet-based science learning on students' metacognitive reflections, epistemological development, and worldviews are suggested.

    We reviewed the literature on standard case management (SCM), intensive case management (ICM), assertive community treatment (ACT), and critical time intervention (CTI) for homeless adults. We searched databases for peer-reviewed English articles published from 1985 to 2011 and found 21 randomized controlled trials or quasi-experimental studies comparing case management to other services. We found little evidence for the effectiveness of ICM. SCM improved housing stability, reduced substance use, and removed employment barriers for substance users. ACT improved housing stability and was cost-effective for mentally ill and dually diagnosed persons. CTI showed promise for housing, psychopathology, and substance use and was cost-effective for mentally ill persons. More research is needed on how case management can most effectively support rapid-rehousing approaches to homelessness. PMID:23947309

    Intraocular gnathostomiasis is a rare parasitic infection caused by the third-stage larvae of spiruroid nematode Gnanthostoma spp. seen mostly in tropical and subtropical regions. It is a food-borne zoonosis caused by ingestion of raw or undercooked freshwater fish, amphibians, reptiles, birds, and mammals, all of which are known to harbor advanced third-stage larvae of Gnanthostoma spp. To date, 74 cases of intraocular gnathostomiasis have been reported from 12 different countries. Only four countries have reported more than 10 cases each, and India shares the rare distinction of being one of them, with 14 cases. Surprisingly, not a single case of cutaneous gnanthostomiasis has ever been reported from India. We present one such case of intraocular gnathostomiasis in a 41-year-old male who presented with an actively motile worm attached to the iris, and we review the pertinent literature of all such cases reported from India.

    AIM: To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM). METHODS: We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA, accessed via PubMed and Google Scholar databases. RESULTS: Ninety-five published cases of LSAA were evaluated and a 25-year-old female, who presented to our clinic with left lower abdominal pain caused by LSAA, is reported. In the reviewed literature, fifty-seven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years. Sixty-six patients had SIT, 23 had MM, three had cecal malrotation, and two had a previously unnoted congenital abnormality. Fifty-nine patients had presented to the hospital with left lower, 14 with right lower and seven with bilateral lower quadrant pain, and seven subjects complained of left upper quadrant pain. The diagnosis was established preoperatively in 49 patients, intraoperatively in 19, and during the postoperative period in five; 14 patients were aware of having this anomaly. The data of eight patients were not unavailable. Eleven patients underwent laparoscopic appendectomy, which was combined with cholecystectomy in two cases. Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients. CONCLUSION: The diagnosis of left lower quadrant pain is based on well-established clinical symptoms, physical examination and physician’s experience. PMID:21105193

    Acupuncture, moxibustion, and cupping, important in traditional Eastern medicine, are increasingly used in the West. Their widening acceptance demands continual safety assessment. This review, a sequel to one our team published 10 years ago, is an evaluation of the frequency and severity of adverse events (AEs) reported for acupuncture, moxibustion, and cupping between 2000 and 2011. Relevant English-language reports in six databases were identified and assessed by two reviewers. During this 12-year period, 117 reports of 308 AEs from 25 countries and regions were associated with acupuncture (294 cases), moxibustion (4 cases), or cupping (10 cases). Country of occurrence, patient's sex and age, and outcome were extracted. Infections, mycobacterial, staphylococcal, and others, were the main complication of acupuncture. In the previous review, we found the main source of infection to be hepatitis, caused by reusable needles. In this review, we found the majority of infections to be bacterial, caused by skin contact at acupoint sites; we found no cases of hepatitis. Although the route of infection had changed, infections were still the major complication of acupuncture. Clearly, guidelines such as Clean Needle Technique must be followed in order to minimize acupuncture AEs. PMID:23573135

    Purpose: To report three cases of optic nerve aplasia (ONA). Case Report: Herein three subjects with ONA are described, two subjects had unilateral involvement. In one of these cases, the fellow eye had an associated persistent hyperplastic primary vitreous (PHPV). The third patient had bilateral ONA with multiple intracranial anomalies. Previous reports are reviewed and reported findings are summarized. Orbital and brain magnetic resonance imaging (MRI) were normal in two of our cases and loss of corpus callosum in the third case. Narrow optic nerve was observed on the right side and normal appearance in other two patients. Conclusion: The diagnosis of optic nerve abnormalities in children requires a thorough ophthalmic examination and proper ancillary testing. Although MRI is valuable in the diagnosis of associated central nervous system anomalies, the optic nerve may appear in normal size and course on MRI images and thus one may not be able to diagnose ONA in eyes with opaque media.

    1987-10-01

    Five human rabies cases were reported in Hong Kong between 1980 and 1984. A review of their clinical data showed only 2 had a definite history of dog bite, while 3 were residents in the infected area. The human outbreak concurred with the epizootic of canine rabies. However, only two cases were diagnosed ante-mortem. Two cases were not even suspected as rabies until proven by post mortem pathological examination. Three of five cases presented as non-specific encephalitis. All the patients died, despite the administration of specific anti-rabies treatment in two cases. Close liaison between the clinician, epidemiologist and pathologist is essential in the management of suspected rabies. Though rabies control is the primary responsibility of the epidemiologist, surveillance data especially in respect of the occurrence of epizootics and human outbreaks as well as the area of infection should be useful to the clinician in patient management.

    Interdisciplinary care for the management of impacted teeth provides a holistic method of treating patients. Careful planning is necessary to reach the desired treatment goals. This article attempts to highlight the importance of diagnosis and adequate treatment planning for successful eruption of impacted teeth. The concept of forced eruption to improve the bone morphology of the impacted teeth has been used to treat a case of multiple impacted teeth. This paper reviews the diagnosis and management of impacted teeth. A case report of multiple impacted maxillary anterior teeth of a 13-year-old female patient has been presented.

    We described 1 case of autoimmune lymphoproliferative syndrome (ALPS), first diagnosed in our hospital, and reviewed the recent literature. The 11-month old male patient presented with a history of splenomegaly and hepatomegaly since 1 month after birth. He suffered recurrent infectious diseases including cytomegalovirus infection, parvovirus B19 infection and chronic diarrhea disease. Besides, his symptoms included hemolytic anemia and thrombocytopenia. The laboratory abnormality indicated an expanded population of alpha/beta double-negative T cells (DNTs) (27.18% of lymphocytes, 35.16% of CD3+ T lymphocytes) in peripheral blood, and autoantibodies including antinuclear antibody, double-stranded DNA and rheumatic factor were positive. Hyper gamma globulinemia and positive direct Coombs tests were seen in the patient. His parents were both healthy and denied autoimmune diseases. We identified a heterozygous point mutation in exon 3 of the FAS gene carrying c.309 A>C, resulting in a single base pair substitution in exon 3 of FAS gene which changed the codon of Arg103 to Ser103. Unfortunately, we were unable to obtain the gene results of the child's parents. The patient was treated with glucocorticoids in our hospital and with mycophenolatemofetil in other hospital. And we were informed that his anemia condition relieved through the telephone follow-up, but he still suffered recurrent infections, hepatomegaly and splenomegaly still existed. As we all know ALPS is characterized by defective lymphocyte apoptosis, and thus cause lymphoproliferative disease and autoimmune disease, and increase the risk of lymphoma. It is more likely to be misdiagnosed as other diseases. ALPS should be suspected in the case of chronic lymphadenopathy, splenomegaly and autoimmune features. Flow cytometry approach is helpful for the diagnosis. Immunosuppressive drugs are the necessary treatment. PMID:26679669

    Background. The risks of occupational asthma (OA) from antibiotics are uncertain. We report 4 new cases and a systematic review of the literature. Methods. Cases were identified through a specialist clinic, each underwent specific provocation testing (SPT). We subsequently reviewed the published literature. Results. The patients were employed in the manufacture of antibiotics; penicillins were implicated in three cases, in the fourth erythromycin, not previously reported to cause OA. In two, there was evidence of specific IgE sensitisation. At SPT each developed a late asthmatic reaction and increased bronchial hyperresponsiveness. 36 case reports have been previously published, 26 (citing penicillins or cephalosporins). Seven cross-sectional workplace-based surveys found prevalences of 5–8%. Conclusions. OA in antibiotic manufacturers may be more common than is generally recognised. Its pathogenesis remains unclear; immunological tests are of uncertain value and potential cases require confirmation with SPT. Further study of its frequency, mechanisms, and diagnosis is required.

  19. Bayesian approach for neural networks--review and case studies.

    PubMed

    Lampinen, J; Vehtari, A

    2001-04-01

    We give a short review on the Bayesian approach for neural network learning and demonstrate the advantages of the approach in three real applications. We discuss the Bayesian approach with emphasis on the role of prior knowledge in Bayesian models and in classical error minimization approaches. The generalization capability of a statistical model, classical or Bayesian, is ultimately based on the prior assumptions. The Bayesian approach permits propagation of uncertainty in quantities which are unknown to other assumptions in the model, which may be more generally valid or easier to guess in the problem. The case problem studied in this paper include a regression, a classification, and an inverse problem. In the most thoroughly analyzed regression problem, the best models were those with less restrictive priors. This emphasizes the major advantage of the Bayesian approach, that we are not forced to guess attributes that are unknown, such as the number of degrees of freedom in the model, non-linearity of the model with respect to each input variable, or the exact form for the distribution of the model residuals.

  20. Fetus in fetu: two case reports and literature review

    PubMed Central

    2014-01-01

    Background Fetus in fetu is a rare congenital anomaly and is defined as a monozygotic twin incorporated into the abdomen of its sibling during development. Fetus in fetu is often overlooked in the differential diagnosis of an abdominal mass. Unlike teratomas, fetus in fetu is a benign disorder. Case presentation We describe the clinical characteristics of two patients, a thirty-months old boy who was found to have abdominal distension and a neonate who was diagnosed antenatally with abdominal mass. Computed tomography scan revealed the mass in which the contents favor a fetus in fetu rather than a teratoma. Surgical removal revealed that the anencephalic fetus have limb buds situated relative to a palpable vertebral column, supporting the diagnosis of fetus in fetu. In the present report, presentation, diagnosis, pathology, management, and recent literature are also reviewed. Conclusion Fetus in fetu is a rare entity that typically presents in infancy and early childhood. It should be differentiated from a teratoma because of the teratoma’s malignant potential. Preoperative diagnosis is based on radiologic findings. The treatment of fetus in fetu is operative to relieve obstruction, prevent further compression and possible complications. Complete excision allows confirmation of the diagnosis and lowers the risk of recurrence. PMID:24693883

    Introduction: Cutaneous metaplastic synovial cyst (CMSC) is a rare cutaneous lesion characterized by a tender subcutaneous nodule, which usually occurs at the site of previous surgical or local trauma. Histologically, the lesion includes a cystic structure with villous-like projections and a lining mimicking hyperplastic synovium. Case Presentation: We reported the first case of CMSC which developed at the surgical incision site of treatment of a maxillofacial fracture. In addition, we reviewed English literature to evaluate all previously reported CMSC cases and discussed its clinical and histopathological features and etiology. From 1987 to now, reviewing the English literature about CMSC includes 17 studies that described 28 cases, and our presented case was the 29th. There was no sex predilection and age of patients ranged from 7 to 82 years, but most of them were over 40 years. We can see this lesion in any site of the body and hand/arm is the most prevalent involved region (28% cases). Most of the patients had a history of previous local trauma or operation in the involved area. Conclusions: Although the actual etiology of CMSC remains unclear, trauma, as the most probable etiologic factor, plays a role in development of CMSC. Surgical excision of the lesion is the preferable treatment choice and rate of recurrence is low. PMID:26756011

    The most common types of orofacial pain originate at the dental or periodontal level or in the musculoskeletal structures. However, the patient may present pain in this region even though the source is located elsewhere in the body. One possible source of heterotopic pain is of cardiac origin. Objectives: Report two cases of orofacial pain of cardiac origin and review the clinical cases described in the literature. Study Design: Description of clinical cases and review of clinical cases. Results and conclusions: Nine cases of atypical pain of cardiac origin are recorded, which include 5 females and 4 males. In craniofacial structures, pain of cardiac origin is usually bilateral. At the craniofacial level, the most frequent location described is in the throat and jaw. Pain of cardiac origin is considered atypical due to its location, although roughly 10% of the cases of cardiac ischemia manifest primarily in craniofacial structures. Finally, the differential diagnosis of pain of odontogenic origin must be taken into account with pain of non-odontogenic origin (muscle, psychogenic, neuronal, cardiac, sinus and neurovascular pain) in order to avoid diagnostic errors in the dental practice as well as unnecessary treatments. Key words:Orofacial pain, ischemic heart disease, heterotopic pain, odontalgia. PMID:22322488

    1992-01-01

    In this paper we discuss the need for interactive factory schedule repair and improvement, and we identify case-based reasoning (CBR) as an appropriate methodology. Case-based reasoning is the problem solving paradigm that relies on a memory for past problem solving experiences (cases) to guide current problem solving. Cases similar to the current case are retrieved from the case memory, and similarities and differences of the current case to past cases are identified. Then a best case is selected, and its repair plan is adapted to fit the current problem description. If a repair solution fails, an explanation for the failure is stored along with the case in memory, so that the user can avoid repeating similar failures in the future. So far we have identified a number of repair strategies and tactics for factory scheduling and have implemented a part of our approach in a prototype system, called CABINS. As a future work, we are going to scale up CABINS to evaluate its usefulness in a real manufacturing environment.

    Erysipelothrix rhusiopathiae is a pathogen of zoonosis often associated with occupational exposure. Although Erysipelothrix rhusiopathiae infection has high mortality, the heart valves in humans are rarely involved. The clinical data of a case of a 65-year-old male with Erysipelothrix rhusiopathiae-induced aortic valve endocarditis was summarized retrospectively and analyzed with a literature review. Based on a literature review and our experience, cases of E. rhusiopathiae-induced aortic valve endocarditis are extremely rare and surgical treatment for this condition is useful and recommended.

    A review of reforms in the financing of hospital services in eight European countries and Australia reveals a commitment to a common objective of relating resource use to hospital workload by means of a standardized case-mix framework in the pursuit of greater efficiency. While this objective is also shared with the U.S. prospective payment system (PPS), it is noteworthy that the majority of countries reviewed favor a global budgeting approach to financing hospital services. Ongoing evaluation of these reforms should facilitate an assessment of the merits of case-mix adjusted global budgeting relative to the patient-based alternative. PMID:10122001

    Background Mycetoma is a chronic granulomatous infection involving cutaneous and subcutaneous tissues. It is endemic in tropical and subtropical areas, but sporadic cases have been reported also in countries of temperate climate. The purpose of this paper is to review the cases of mycetoma in European subjects (and presumably acquired in Europe), to give an insight in the main factors associated with this condition, and to describe two previously unpublished cases observed at our Centre. Methods and Findings PubMed was systematically searched for case reports and case series of mycetoma in Europeans reported between 1980 and 2014, using specific search strategies. Two further cases diagnosed by the authors are described. Forty-two cases were collected. Eleven cases were caused by Scedosporium apiospermium, mainly in immunosuppressed patients from Bulgaria, Germany, the Netherlands, Portugal, Slovenia, Spain and the United Kingdom. Excluding all patients with immunosuppression, 29 cases remain. Most of them were reported from Bulgaria and in Albanian patients (all diagnosed outside Albania). In the Bulgarian case series many different micro-organisms, both bacteria and fungi, were isolated, while all the 5 cases from Albania were caused by Actinomadura spp. Other countries reporting cases were Greece, Italy and Turkey. In general, Actinomadura spp is the most frequent causative agent isolated, followed by Nocardia spp and Madurella mycetomatis. The foot was the most reported site involved. Most patients were medically treated, but unfortunately a long-term follow up (at least one year) was available only in a few cases. Conclusions Our review and our own cases suggest that Europeans without travel history can be affected by Madura foot. The lack of a surveillance system is likely to cause an underreporting of cases. Moreover, the unfamiliarity of Western doctors with this peculiar infection may cause a mismanagement, including unnecessary amputations. PMID:24963778

    Nurse educators are challenged to keep up with highly specialised clinical practice, emerging research evidence, regulation requirements and rapidly changing information technology while teaching very large numbers of diverse students in a resource constrained environment. This complex setting provides the context for the CaseWorld project, which aims to simulate those aspects of clinical practice that can be represented by e-learning. This paper describes the development, implementation and evaluation of CaseWorld, a simulated learning environment that supports case based learning. CaseWorld provides nursing students with the opportunity to view unfolding authentic cases presented in a rich multimedia context. The first round of comprehensive summative evaluation of CaseWorld is discussed in the context of earlier formative evaluation, reference group input and strategies for integration of CaseWorld with subject content. This discussion highlights the unique approach taken in this project that involved simultaneous prototype development and large scale implementation, thereby necessitating strong emphasis on staff development, uptake and engagement. The lessons learned provide an interesting basis for further discussion of broad content sharing across disciplines and universities, and the contribution that local innovations can make to global education advancement.

    2013-01-01

    Background During the 2009 influenza pandemic, uncertainty surrounding the seriousness of human infections with the H1N1pdm09 virus hindered appropriate public health response. One measure of seriousness is the case fatality risk, defined as the probability of mortality among people classified as cases. Methods We conducted a systematic review to summarize published estimates of the case fatality risk of the pandemic influenza H1N1pdm09 virus. Only studies that reported population-based estimates were included. Results We included 77 estimates of the case fatality risk from 50 published studies, about one-third of which were published within the first 9 months of the pandemic. We identified very substantial heterogeneity in published estimates, ranging from less than 1 to more than 10,000 deaths per 100,000 cases or infections. The choice of case definition in the denominator accounted for substantial heterogeneity, with the higher estimates based on laboratory-confirmed cases (point estimates= 0–13,500 per 100,000 cases) compared with symptomatic cases (point estimates= 0–1,200 per 100,000 cases) or infections (point estimates=1–10 per 100,000 infections). Risk based on symptomatic cases increased substantially with age. Conclusions Our review highlights the difficulty in estimating the seriousness of infection with a novel influenza virus using the case fatality risk. In addition, substantial variability in age-specific estimates complicates the interpretation of the overall case fatality risk and comparisons among populations. A consensus is needed on how to define and measure the seriousness of infection before the next pandemic. PMID:24045719

    Cerebral salt wasting syndrome (CSWS) is characterized by severe natriuresis and volume depletion in the presence of cerebral pathology. In literature, there are few reports about tuberculous meningitis and cerebral CSWS. In this article, we report two tuberculous meningitis cases with CSWS and present a review of the literature on this topic. Cerebral salt wasting diagnosis was based on hyponatraemia associated with high urinary sodium excretion and inappropriately high urine output in the presence of dehydration. Treatment was made with sodium-fluid replacement plus fludrocortisone therapy in both cases. In agreement with the literature we argue that cerebral salt wasting syndrome might be more common than the syndromes of inappropriate antidiuretic hormone secretion (SIADH) in cerebral disorders. Differentiating the cerebral salt wasting syndrome from the SIADH is very important because unrecognized cerebral salt wasting syndrome can lead to inadequate management and result in unnecessary hyponatremia-related morbidity. The electrolyte and hydration status of patients should be monitored closely in patients with tuberculous meningitis. PMID:26454484

    The paper presents a review of structural measures that were taken to cope with floods in some cities along the Danube River, such as Vienna, Bratislava, and Belgrade. These cities were also considered as case studies within the KULTURisk project. The structural measures are reviewed and compared to each other according to the type, duration of application, the return period of the design flood event, how the project measures are integrated into spatial planning and the problems that occur in the flood defences today. Based on this review, some suggestions are given on how to improve the flood risk management in flood-prone areas.

    PubMed Central

    2013-01-01

    Background Strongyloidiasis is commonly a clinically unapparent, chronic infection, but immuno suppressed subjects can develop fatal disease. We carried out a review of literature on hyperinfection syndrome (HS) and disseminated strongyloidiasis (DS), in order to describe the most challenging aspects of severe strongyloidiasis. Methods We conducted a structured search using PubMed to collect case reports and short case series on HS/DS published from 1991 to 2011. We restricted search to papers in English, Spanish, Italian and French. Case reports were classified as HS/DS according to given definitions. Results Records screened were 821, and 311 were excluded through titles and abstract evaluation. Of 510 full-text articles assessed for eligibility, 213 were included in qualitative analysis. As some of them were short case series, eventually the number of cases analyzed was 244. Steroids represented the main trigger predisposing to HS and DS (67% cases): they were mostly administered to treat underlying conditions (e.g. lymphomas, rheumatic diseases). However, sometimes steroids were empirically prescribed to treat signs and symptoms caused by unsuspected/unrecognized strongyloidiasis. Diagnosis was obtained by microscopy examination in 100% cases, while serology was done in a few cases (6.5%). Only in 3/29 cases of solid organ/bone marrow transplantation there is mention of pre-transplant serological screening. Therapeutic regimens were different in terms of drugs selection and combination, administration route and duration. Similar fatality rate was observed between patients with DS (68.5%) and HS (60%). Conclusions Proper screening (which must include serology) is mandatory in high - risk patients, for instance candidates to immunosuppressive medications, currently or previously living in endemic countries. In some cases, presumptive treatment might be justified. Ivermectin is the gold standard for treatment, although the optimal dosage is not clearly defined in

    Purpose. Pancreaticopericardial fistula (PPF) is an extremely rare complication of acute or chronic pancreatitis. This paper presents a rare case of PPF and provides systematic review of existing cases from 1970 to 2014. Methods. A PubMed search using key words was performed for all the cases of PPF from January 1970 to December 2014. Fourteen cases were included in the study. The cases were reviewed for demographic characteristics, diagnostic modalities, and treatment. Descriptive analysis of these variables was performed. Results. Median age was 43 years. 78% were known alcoholics and 73.3% had chronic pancreatitis. Dyspnea was present in 78%. Cardiac tamponade was present in 53%; 75% of patients had known chronic pancreatitis (RR = 0.74). Surgery was associated with best treatment outcomes and 50% of patients who underwent endoscopic treatment survived. Conclusion. PPF is a rare disease. This paper indicates that acute cardiac tamponade in patients with history of alcoholism and chronic pancreatitis could be a sign of an existing pancreaticopericardial fistula and early surgical intervention could be life-saving.

    Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented. PMID:25497289

    Geographic tongue is a benign recurrent condition of uncertain aetiology affecting the tongue characterized by loss of epithelium especially filiform papillae giving a characteristic appearance. The clinical presentation may vary from asymptomatic to painful and burning ulceration. The condition is commonly seen in adults but few cases are reported in children. A case of asymptomatic geographic tongue in three-year-old male child and literature review with new insight in aetiology is presented here. Management depends on the clinical condition and underlying aetiology. PMID:27042597

    Hemangioblastoma (HBL) within the central nervous system is a benign vascular neoplasm that usually occurs in the cerebellum. Supratentorial occurrence of HBL is an extremely rare event. Till date, approximately 129 cases of supratentorial HBL have been reported in the literature. Here, we present three new cases of supratentorial hemangioblatomas, one of which was found to have the lesions in a unique location of the choroidal fissure. The clinical, histopathological, and neuroradiological characteristics, as well as management of this rare disease are discussed with a review of the pertinent literature. PMID:23207666

    A sixteen year old cat was examined because of polyphagia and weight loss. On the basis of elevated thyroxine levels and the clinical presentation a diagnosis of hyperthyroidism was made. The cat was treated presurgically with propylthiouracil and propranolol. Surgical excision of the grossly affected thyroid lobe, and partial excision of the apparently normal contralateral lobe was carried out. The cat improved clinically after the surgery but elevated thyroxine levels persisted. This case and the literature review, which is presented also, stress the necessity to either demonstrate unilateral involvement via extensive presurgical work-up, or to do bilateral, or staged bilateral thyroidectomies in cases of feline hyperthyroidism.

    Inflammatory myofibroblastic tumor (IMT) or (plasma cell granuloma) of the larynx is a rare benign lesion that usually involves the lungs and broncopulmonary tree, as well as abdominal viscera. Overall this kind of tumor represents less than 1% of all tumors in the lung and respiratory tract with only 31 cases reported to date in the English language literature of laryngeal IMT. We report the first 2 cases in Saudia Arabia of IMT of the larynx treated at King Abdulaziz University Hospital (KAUH) with literature review. PMID:23267296

    Lingual osseous choristoma is an extremely rare condition, of which only 61 cases have been reported. Monserrat in 1913 was the first to report this bony lesion on the dorsum of the tongue and it was labelled as lingual osteoma, the term that normally describes neoplastic pathology. Krolls et al changed this term later to osseous choristoma, which means normal tissue in an abnormal location. The aetiology and pathogenesis of lingual osseous choristoma remain debatable. We report a case of lingual osseous choristoma and review the literature. PMID:21503232

    Trisomy 8 mosaicism (Warkany syndrome) is a rare viable condition with variable phenotypes, ranging from mild dysmorphic features to severe malformations. Karyotyping and fluorescence in-situ hybridization potentially help detecting this low mosaic clone to confirm the diagnosis of patients with classical and unusual clinical presentations. This report reviews few previous cases to describe our case - a boy who had trisomy 8 mosaicism with severe dysmorphic features, born to a consanguineous Arabic couple. This study concludes that careful cytogenetic diagnoses of trisomy 8 mosaicism is essential for appropriate management and follow up of this rare disorder.

    Background: Extradural spinal mass lesions are most commonly metastatic tumors. Extradural meningiomas are rare, accounting for approximately 2.5–3.5% of spinal meningiomas; intraoperatively, they are easily mistaken for malignant tumors, especially in the en plaque variety, resulting in inadequate surgical treatment. Case Description: Our case is one of the first to describe a patient with two purely extradural meningiomas, one each between D3–D4 and between D5–D6 vertebral levels. Surgical resection was radical, and pathologically both lesions were meningothelialmeningiomas. Conclusions: Reviewing the literature, we discuss the pathogenesis, treatment strategies, and long-term behavior of these uncommon lesions.

    Foregut cystic developmental malformation (FCDM) is a very rare lesion of the alimentary tract, especially in the stomach. We discuss the concepts of gastric duplication cyst, bronchogenic cysts, and FCDM. Nomenclature has been inconsistent and confusing, but, by some definitions, gastric duplication cysts involve gastric mucosa and submucosal glands, bronchogenic cysts involve respiratory mucosa with underlying cartilage and glands, and FCDM lacks gastric mucosa or underlying glands or cartilage but has pseudostratified ciliated columnar epithelium (PCCE). We searched our departmental case files from the past 15 years and identified 12 cases of FCDM in the alimentary tract. We summarize the features of these 12 cases including a report in detail on a 52-year-old man with a submucosal cyst lined with simple PCCE and irregular and stratified circular muscle layers that merged with gastric smooth muscle bundles near the lesser curvature of the gastric cardia. A literature review of cases with this histology yielded 25 cases. We propose the term gastric-FCDM for such cases. Our own series of 12 cases confirms that preoperative recognition of the entity is infrequent and problematic. The rarity of this developmental disorder, as well as a lack of understanding of its embryologic origins, may contribute to missing the diagnosis. Not appreciating the diagnosis preoperatively can lead to an inappropriate surgical approach. In contrast, presurgical recognition of the entity will contribute to a good outcome and reduced risk of complications. PMID:25593458

    Motivated by their unique structure and excellent properties, significant progress has been made in recent years in the development of graphene-based fibers (GBFs). Potential applications of GBFs can be found, for instance, in conducting wires, energy storage and conversion devices, actuators, field emitters, solid-phase microextraction, springs, and catalysis. In contrast to graphene-based aerogels (GBAs) and membranes (GBMs), GBFs demonstrate remarkable mechanical and electrical properties and can be bent, knotted, or woven into flexible electronic textiles. In this review, the state-of-the-art of GBFs is summarized, focusing on their synthesis, performance, and applications. Future directions of GBF research are also proposed. PMID:26248041

    Staphylococcus intermedius and Staphylococcus pseudintermedius are difficult to distinguish using conventional microbiological methods. Molecular diagnostic tools change our understanding of the epidemiology of these 2 organisms. In this study, we present (1) a detailed review of the current literature on molecular diagnostics and (2) a case series in which misidentification was proven in 1 case. We conclude that S pseudintermedius is a more common human pathogen than previously recognized. PMID:26509181

    While yoga is gaining increased popularity in North America and Europe, its safety has been questioned in the lay press. The aim of this systematic review was to assess published case reports and case series on adverse events associated with yoga. Medline/Pubmed, Scopus, CAMBase, IndMed and the Cases Database were screened through February 2013; and 35 case reports and 2 case series reporting a total of 76 cases were included. Ten cases had medical preconditions, mainly glaucoma and osteopenia. Pranayama, hatha yoga, and Bikram yoga were the most common yoga practices; headstand, shoulder stand, lotus position, and forceful breathing were the most common yoga postures and breathing techniques cited. Twenty-seven adverse events (35.5%) affected the musculoskeletal system; 14 (18.4%) the nervous system; and 9 (11.8%) the eyes. Fifteen cases (19.7%) reached full recovery; 9 cases (11.3%) partial recovery; 1 case (1.3%) no recovery; and 1 case (1.3%) died. As any other physical or mental practice, yoga should be practiced carefully under the guidance of a qualified instructor. Beginners should avoid extreme practices such as headstand, lotus position and forceful breathing. Individuals with medical preconditions should work with their physician and yoga teacher to appropriately adapt postures; patients with glaucoma should avoid inversions and patients with compromised bone should avoid forceful yoga practices.

    This study aims to explore practice, use, and risk of electroconvulsive therapy (ECT) in pregnancy. A systematic search was undertaken in the databases Medline, Embase, PsycINFO, SveMed and CINAHL (EBSCO). Only primary data-based studies reporting ECT undertaken during pregnancy were included. Two reviewers independently checked study titles and abstracts according to inclusion criteria and extracted detailed use, practice, and adverse effects data from full text retrieved articles. Studies and extracted data were sorted according to before and after year 1970, due to changes in ECT administration over time. A total of 67 case reports were included and studies from all continents represented. Altogether, 169 pregnant women were identified, treated during pregnancy with a mean number of 9.4 ECTs, at mean age of 29 years. Most women received ECT during the 2nd trimester and many were Para I. Main diagnostic indication in years 1970 to 2013 was Depression/Bipolar disorder (including psychotic depression). Missing data on fetus/child was 12 %. ECT parameter report was often sparse. Both bilateral and unilateral electrode placement was used and thiopental was the main anesthetic agent. Adverse events such as fetal heart rate reduction, uterine contractions, and premature labor (born between 29 and 37 gestation weeks) were reported for nearly one third (29 %). The overall child mortality rate was 7.1 %. Lethal outcomes for the fetus and/or baby had diverse associations. ECT during pregnancy is advised considered only as last resort treatment under very stringent diagnostic and clinical indications. Updated international guidelines are urgently needed. PMID:24271084

    Neonatal lupus erythematosus is an infrequent disease seen in newborns. It is caused by transplacental maternal autoantibody passage. Cutaneous involvement and congenital heart block (CHB) are the most common affections, although it may involve multiple organs like the liver, lungs, blood, nervous or digestive systems. This article present a review of the four cases diagnosed in the past five years in a Neonatal Unit, which shows the different clinical spectrum which can develop around this disease (CHB, multisystemic affection and two cutaneous cases), different autoantibodies (specially anti-SSA) with an early negativization during the first year of life and the possibility of future collagen vascular disease as occurred in one case.

    Trisomy 9 is a relatively uncommon chromosome abnormality that may sometimes be seen in the nonmosaic state. We reviewed 23 mosaic and 15 nonmosaic cases of trisomy 9, including 2 new cases, in order to better define the prognosis and phenotype of this disorder. A recognizable trisomy 9 phenotype was identified and included a {open_quotes}bulbous{close_quotes} nose, microphthalmia, and dislocated limbs. Other nonspecific anomalies involving various organ systems were also common. With one exception, all survivors had severe mental impairment. Mosaicism for trisomy 9 predicted longer survival, but the degree of mosaicism in lymphocytes or fibroblasts did not predict survival or degree of impairment. Parental chromosome variations were not uncommon. In contrast to prior reports, no specific prognostic finding was identified. A meiotic origin with loss of a trisomic cell line in mosaic cases is suggested. 43 refs., 2 figs., 2 tabs.

    Tuberculous radiculomyelitis (TBRM) is a complication of tuberculous meningitis (TBM), which has been reported rarely in the modern medical literature. We describe a case of TBRM that developed in an human immunodeficiency virus (HIV)-infected patient, despite prompt antituberculous treatment. To our knowledge, this is the second case of TBRM reported in an HIV-infected patient. We also review 74 previously reported cases of TBRM. TBRM develops at various periods after TBM, even in adequately treated patients after sterilization of the cerebrospinal fluid (CSF). The most common symptoms are subacute paraparesis, radicular pain, bladder disturbance, and subsequent paralysis. CSF evaluation usually shows an active inflammatory response with a very high protein level. MRI and CT scan are critical for diagnosis, revealing loculation and obliteration of the subarachnoid space along with linear intradural enhancement. As in other forms of paradoxical reactions to antituberculous treatment, there is evidence that steroid treatment might have a beneficial effect. PMID:10854362

    Patients with altered taste perception following stroke are at risk for malnutrition and associated complications that may impede recovery and adversely affect quality of life. Such deficits often induce and exacerbate depressive symptomatology, which can further hamper recovery. It is important for clinicians and rehabilitation specialists to monitor stroke patients for altered taste perception so that this issue can be addressed. The authors present the case of a patient who experienced an isolated ischemic infarct affecting a primary cortical taste area. This case is unusual in that the isolated injury allowed the patient to remain relatively intact cognitively and functionally, and thus able to accurately describe her taste-related deficits. The case is further used to describe the relevant neurological taste pathways and review potential taste-related therapies. PMID:23340074

    Thyroid storm developed following radioiodine therapy in a 43-year-old man with Graves' disease, weight loss, myopathy, severe thyrotoxic hypercalcemia, and a pituitary adenoma. The hypercalcemia may have been a significant, and previously unreported, predisposing factor for the radioiodine-associated thyroid storm. This case and 15 other well-documented cases of radioiodine-associated storm found in the literature are reviewed, as are several other cases of less severe exacerbations of thyrotoxicosis associated with radioiodine therapy. Although not often seen, these complications are often fatal. High-risk patients, such as the elderly, those with severe thyrotoxicosis, and those with significant underlying diseases, may benefit from preventive measures such as the judicious use of thyrostatic medications during the periods before and after isotope administration.

  5. Streptococcus gordonii septic arthritis : two cases and review of literature

    PubMed Central

    2012-01-01

    Background Despite advances in antimicrobial and surgical therapy, septic arthritis remains a rheumatologic emergency that can lead to rapid joint destruction and irreversible loss of function. In adults, Staphylococcus aureus is the most common microorganism isolated from native joints. Streptococcus gordonii is a prominent member of the viridans group of oral bacteria and is among the bacteria most frequently identified as being primary agent of subacute bacterial endocarditis. To the best of our knowledge, Streptococcus gordonii has not yet been described as agent of septic arthritis. Case Presentation We describe here two cases of septic arthritis due to Streptococcus gordonii. It gives us an opportunity to review epidemiology, diagnosis criteria and management of septic arthritis. Conclusion Although implication of S. gordonii as aetiologic agent of subacute endocarditis is well known, this organism is a rare cause of septic arthritis. In this case, the exclusion of associated endocarditis is warranted. PMID:22974507

    Extra-adrenal myelolipoma is a relatively rare entity, with fewer than 50 cases reported in literature. We present a case of a 79 year-old female who presented for evaluation of hip fracture following trauma, where a lobulated presacral mass with mixed fat/soft tissue attenuation was incidentally seen on initial bone algorithm pelvic CT. Subsequent MRI showed signal characteristics of a lesion with mixed fat and soft tissue composition. The lesion demonstrated stability on follow-up imaging. An elective surgical resection was performed which yielded a grossly fatty mass. The diagnosis of presacral myelolipoma was confirmed on microscopic examination. Following description of our case, we conduct a literature review of the imaging characteristics, diagnosis, and treatment of presacral myelolipoma. PMID:23378876

    It is exceptional to "forget" a compress in a operative wound, but the consequence are important. We report 25 cases of textilomes operated over a period of 18 years. There were 18 cases involving visceral surgery and 7 involving bone surgery. Sixty percent of the patients were women and 82% were adults. Emergency surgery was required in 70% of the bone operations and in only 33% of the visceral indications. Twelve percent of the cases were discovered fortuitously and 40% led to pain or occlusion, 24% leading to a digestive tract fistula and 24% to an inflammatory tumour formation. Standard X-rays and echography were sufficient for diagnosis in the abdominal cases. CT scan or MRI may be useful. Ablation of the abdominal foreign body was the followed by complications in two-thirds of the cases with a mortality of 25%. No deaths were observed in the other localizations but the functional result was impaired. We reviewed the literature reporting 117 such cases. PMID:7743846

In addition, the study analyzed the existing literature on these lesions. Gastric bronchogenic cysts are more common in females (female:male ratio, 21:14) and the median age of their development is 43 years. In total, 48.57% of the 34 previously reported cases were identified incidentally, and the remainder presented mainly with epigastric pain. Cyst sizes varied between 1.7 and 15 cm. In 3 cases, preoperative diagnosis was performed using needle biopsy, whereas several studies were initially misdiagnosed as stromal tumors. In 85% of the cases (31/35), cyst resection was performed, with laparoscopy used in 4 of the cases. The findings of the present study and literature review suggested that bronchogenic cysts of the stomach are rare, and surgical resection is warranted to treat symptoms and prevent malignant transformation.

    We present a case with trisomy of the short arm of chromosome 4, i.e., 46,XX,der(22)t(4;22)(p12;11.2). The most notable clinical findings included: prominent forehead, hypertelorism, small, bulbous nose with depressed and broad bridge, low hairline, retrognathia, notched auricular helix, rocker-bottom feet with prominent heel, arachnodactyly and comptodactyly. An additional, unique finding in our case is the presence of 13 ribs. In the past, the precise characterization of cases with trisomy for the 4p segment has been difficult by routine cytogenetic techniques because the bands involved in this abnormality are quite variable. We used the FISH technique, applying a battery of probes to delineate the genomic morbidity at the molecular level. In our case, the entire short arm is in the trisomic state, yet it could not be identified as a distinct syndrome prior to cytogenetic evaluation. The phenotypic spectrum associated with this gross chromosomal abnormality has been the subject of debate and scrutiny. We provided a comprehensive review of 64 cases and it is concluded that the clinical manifestations of the pure trisomy 4p syndrome are associated with trisomy of the distal two thirds to the entire p arm and that the additional material does not cause a more severe phenotype. Therefore, the molecular characterization of the short arm of chromosome 4 (4p) may be imperative in order to correlate the clinical expression with chromosome bands and ultimately with specific gene(s) in future cases.

    ABSTRACT OBJECTIVE To evaluate family physicians’ enjoyment of and knowledge gained from game-based learning, compared with traditional case-based learning, in a continuing medical education (CME) event on stroke prevention and management. DESIGN An equivalence trial to determine if game-based learning was as effective as case-based learning in terms of attained knowledge levels. Game questions and small group cases were developed. Participants were randomized to either a game-based or a case-based group and took part in the event. SETTING Ontario provincial family medicine conference. PARTICIPANTS Thirty-two family physicians and 3 senior family medicine residents attending the conference. INTERVENTION Participation in either a game-based or a case-based CME learning group. MAIN OUTCOME MEASURES Scores on 40-item immediate and 3-month posttests of knowledge and a satisfaction survey. RESULTS Results from knowledge testing immediately after the event and 3 months later showed no significant difference in scoring between groups. Participants in the game-based group reported higher levels of satisfaction with the learning experience. CONCLUSION Games provide a novel way of organizing CME events. They might provide more group interaction and discussion, as well as improve recruitment to CME events. They might also provide a forum for interdisciplinary CME. Using games in future CME events appears to be a promising approach to facilitate participant learning. PMID:20841574

    Objective. To summarize the characteristics and analysis of relevant factors and to give references for prevention and further study of liver damage associated with Polygonum multiflorum Thunb. (HSW), we provide a systematic review of case reports and case series about liver damage associated with HSW. Methods. An extensive search of 6 medical databases was performed up to June 2014. Case reports and case series involving liver damage associated with HSW were included. Results. This review covers a total of 450 cases in 76 articles. HSW types included raw and processed HSW decoction pieces and many Chinese patent medicines that contain HSW. Symptoms of liver damage occur mostly a month or so after taking the medicine, mainly including jaundice, fatigue, anorexia, and yellow or tawny urine. Of the 450 patients, two cases who received liver transplantation and seven who died, the remaining 441 cases recovered or had liver function improvement after discontinuing HSW products and conservative care. Conclusion. HSW causes liver toxicity and may cause liver damage in different degrees and even lead to death; most of them are much related to long-term and overdose of drugs. Liver damage associated with HSW is reversible, and, after active treatment, the majority can be cured. People should be alert to liver damage when taking HSW preparations. PMID:25648693

    Abstract Introduction Sexual dysfunction is a well‐known side effect of antidepressants. Painful ejaculation is a rare side effect that has been reported with the use of some psychiatric drugs such as triclyclic antidepressants. Cyclobenzaprine is a muscle relaxant that is structurally similar to tricyclic antidepressants. It is the most commonly prescribed muscle relaxant in the United States and accounts for 18% of all prescriptions written for chronic back pain. Methods A 55‐year‐old man was referred to our pain medicine clinic for evaluation and treatment of pain with ejaculation. Main outcome Measure The main outcome measure was to review the current published literature and case reports on painful ejaculation from medication use, in particular tricyclic antidepressants. Results After discontinuation of cyclobenzaprine, our patient's sexual dysfunction resolved. This result was consistent with the literature reviewed on the topic. Conclusion Painful ejaculation is likely an underreported side effect of tricyclic antidepressants and cyclobenzaprine use. Fortunately, these symptoms are reversible and discontinuation of these medications is typically an effective cure. K raus MB , W ie CS , G orlin AW , W isenbaugh ES , and R osenfeld DM .

    2010-01-01

    The aim of this review was to describe a patient with serotonin toxicity after an overdose of dextromethorphan and chlorphenamine and to perform a systematic literature review exploring whether dextromethorphan and chlorphenamine may be equally contributory in the development of serotonin toxicity in overdose. A Medline literature review was undertaken to identify cases of serotonin toxicity due to dextromethorphan and/or chlorphenamine. Case reports were included if they included information on the ingested dose or plasma concentrations of dextromethorphan and/or chlorphenamine, information about co-ingestions and detailed clinical information to evaluate for serotonin toxicity. Cases were reviewed by two toxicologists and serotonin toxicity, defined by the Hunter criteria, was diagnosed when appropriate. The literature was then reviewed to evaluate whether chlorphenamine may be a serotonergic agent. One hundred and fifty-five articles of dextromethorphan or chlorphenamine poisoning were identified. There were 23 case reports of dextromethorphan, of which 18 were excluded for lack of serotonin toxicity. No cases were identified in which serotonin toxicity could be solely attributed to chlorphenamine. This left six cases of dextrometorphane and/or chlorphenamine overdose, including our own, in which serotonin toxicity could be diagnosed based on the presented clinical information. In three of the six eligible cases dextromethorphan and chlorphenamine were the only overdosed drugs. There is substantial evidence from the literature that chlorphenamine is a similarly potent serotonin re-uptake inhibitor when compared with dextrometorphan. Chlorphenamine is a serotonergic medication and combinations of chlorphenamine and dextromethorphan may be dangerous in overdose due to an increased risk of serotonin toxicity. PMID:21175434

    Fruit biomechanics is needed for quality determination, multiscale modelling and engineering design of fruit processes and equipments. However, these determined fruit biomechanics data often have obvious differences for the same fruit or tissue. In order to investigate it, the fruit biomechanics based on anatomy was reviewed in this paper. First, the anatomical characteristics of fruit biomaterials were described at the macroscopic `tissue' level and microscopic `cellular' level. Subsequently, the factors affecting fruit biomechanics based on anatomy and the relationships between fruit biomechanics, texture and mechanical damage were summarised according to the published literature. Fruit biomechanics is mainly affected by size, number and arrangement of cells, quantity and volume of intracellular spaces, structure, thickness, chemical composition and permeability of cell walls, and pectin degradation level and turgor pressure within cells based on microanatomy. Four test methods and partial determined results of fruit biomechanics were listed and reviewed. The determined mechanical properties data of fruit are only approximate values by using the existing four test methods, owing to the fruit biomaterials being non-homogeneous and living. Lastly, further aspects for research on fruit biomechanics were proposed for the future.

    Purpose: To present the case of an 18 month old boy with Coats' disease who was found to have anterior chamber cholesterolosis. Methods: Case presentation and review of reported cases. Results: An 18 month old boy presented with unilateral stage 3B Coats' disease without other clinical findings. Two weeks after presentation he returned with xanthocoria due to anterior chamber cholesterolosis. He subsequently developed hyphema, neovascular glaucoma, and was enucleated. His case is compared to all previously reported cases of Coats' disease leading to anterior chamber cholesterolosis. Conclusion: The presentation of anterior chamber cholesterolosis in Coats' disease can range from the incidental finding in an asymptomatic patient to acute angle closure glaucoma with pain and acutely decreased vision. Clinicians should be aware of this potential complication of Coats' disease as it denotes a poor visual prognosis. PMID:27014384

    Stenotrophomonas (Xanthomonas) maltophilia is a rare cause of endocarditis. The extensive resistance of this organism to several antibiotics leaves few options for antimicrobial therapy. In vitro synergism of the combination of trimethoprim-sulfamethoxazole (TMP-SMZ) and ticarcillin/clavulanic acid (TIC/CA) has been demonstrated. To our knowledge, we report the first case of ventriculoatrial cerebrospinal fluid shunt-associated endocarditis due to S. maltophilia. The patient was cured with combination therapy with TMP-SMZ and TIC/CA along with catheter removal. This is also the first report of S. maltophilia endocarditis successfully treated with this antibiotic combination. In a review of the medical literature, only 16 cases of S. maltophilia endocarditis were found. Most patients were intravenous drug users (43.8%) or had either prosthetic heart valves (50%) or an indwelling vascular catheter (18.8%). Although S. maltophilia is usually considered a nosocomial pathogen, about one-half of the cases were community-acquired. Twelve of sixteen patients had left-sided endocarditis. Therapy with a combination of two or more antibiotics was employed in most cases. Seven patients had been given TMP-SMZ therapy, but none had been treated with TIC/CA before. One-half of the patients required cardiac surgery. The overall mortality rate was 33%. Although the optimal antibiotic treatment for S. maltophilia endocarditis remains unknown, the case reported herein reinforces in vitro findings that the combination of TMP-SMZ and TIC/CA may be effective therapy.

    INTRODUCTION Penile cancer is an uncommon disease affecting only about one in 100,000 men worldwide in a year. The diagnosis of the condition is frequently delayed, and the disease and its treatment frequently result in significant morbidity in patients. METHODS We herein describe seven cases of penile tumours: six cases of squamous cell carcinomas and one case of B-cell lymphoma that presented to our hospital’s urology department between March 2011 and October 2012. We reviewed the literature to discuss the clinical presentation, natural history and current management of penile cancer. RESULTS The patients were followed up for 1–24 months. They were managed according to their disease stage and lymph node status. Four out of seven patients showed disease progression during the follow-up period. CONCLUSION The accurate staging of inguinal nodes in cases of low-risk disease is important to prescribe appropriate surgery for the inguinal nodes. Aggressive management of inguinal and pelvic lymph nodes remains the cornerstone in the treatment of high-risk disease cases. PMID:26668410

    The UK has a well-established programme of Confidential Enquiries into Maternal Deaths and a national system for research into near-miss maternal morbidities, the UK Obstetric Surveillance System. The addition of a programme of near-miss case reviews, the Confidential Enquiries into Maternal Morbidity, permits a complete examination of the incidence, risk factors, care and outcomes of the severest complications in pregnancy, and enables the lessons learnt to improve future care to be identified more quickly. This in turn allows for more rapid inclusion of recommendations into national guidance and hence the potential of better health for both women and babies. PMID:25236644

    Brown tumors are focal bone lesions, encountered in patients with uncontrolled hyperparathyroidism. They can be located in any part of the skeleton. Clinically significant lesions in the craniofacial bones are rare. Craniofacial involvement may cause facial disfiguration and compromise social ease of the patient and normal functions, such as chewing, talking, and breathing. In this case report, we present a patient with a brown tumor of the craniofacial bones provoked by secondary hyperparathyroidism and review the last 10 years of craniofacial brown tumors associated with secondary hyperparathyroidism in the English literature.

    Angiography with selective embolization has become an accepted method of treating posterior epistaxis that is not controlled with conservative measures. The authors reviewed 112 cases of patients who had received selective angiographic embolization for refractory epistaxis from January 1990 to December 1995. There were 114 embolizations over this 5-year period. The immediate success rate was 93%, with long-term success achieved in 88% of patients. The overall complication rate was 17%, with the long-term morbidity rate less than 1%. Selective angiographic embolization is a safe and effective method that should be considered in the treatment of refractory epistaxis. PMID:9546280

    A 24-year-old male presented with eight months of increasingly severe frontal headaches, decreased right facial sensation, and periodic vertigo. Magnetic resonance imaging demonstrated a heterogeneously contrast-enhancing mass involving and expanding the right foramen ovale.  A biopsy of the lesion was performed, and the final pathologic diagnosis revealed a neoplastic rhabdomyoma. To date, only five cases of intracranial rhabdomyoma have been reported, and a rhabdomyoma involving the trigeminal nerve has never been described in an adult. This manuscript reviews the available literature and highlights the clinical, imaging, pathologic characteristics, and surgical management of these exceedingly rare lesions.

    We report an unusual case of gastric carcinosarcoma with rhabdomyosarcomatous and neudoendocrinal differentiation in a 71-year-old Japanese female. Gastric carcinosarcoma with rhabdomyosarcomatous and neuroendocrinal differentiation is a rare tumor. The tumor developed in the body of the stomach and was exophytic in appearance. By histochemical analysis, the tumor was shown a part of positive for desmin and myoglobin and a part of positive for synaphtophysin and vimentin.We conclude that, though rare, gastric carcinosarcoma with rhabdomyosarcomatous and neuroendocrinal differentiation thus is reviewed in the English literatures.

    The anatomic and physiologic changes that occur during pregnancy are unique. A neurologist needs to be aware of normal pregnancy-induced physiologic changes in the cardiovascular, renal, hematologic, and autoimmune systems, and the local anatomic changes, which include alteration of body habitus and pelvic ligaments. These changes are clearly advantageous, but in certain circumstances may predispose to pathology. In addition, pregnancy effects treatment of chronic neurologic conditions as regards medication safety and metabolism. This case-oriented review discusses the important aspects of pregnancy physiology and an approach to treatment of common disorders encountered during pregnancy including stroke, multiple sclerosis, epilepsy, and compression neuropathies.

    Jaguar attacks on humans rarely occur in the wild. When they do, they are often fatal. We describe a jaguar attack on a three-year-old girl near her home deep in a remote area of the Guyanese jungle. The patient had a complex but, relatively, rapid transport to a medical treatment facility for her life-threatening injuries. The child, who suffered typical jaguar-inflicted injury patterns and survived, is highlighted. We review jaguar anatomy, environmental status, hunting and killing behaviors, and discuss optimal medical management, given the resource-limited treatment environment of this international emergency medicine case.

    Recommender systems are a vital tool that helps us to overcome the information overload problem. They are being used by most e-commerce web sites and attract the interest of a broad scientific community. A recommender system uses data on users' past preferences to choose new items that might be appreciated by a given individual user. While many approaches to recommendation exist, the approach based on a network representation of the input data has gained considerable attention in the past. We review here a broad range of network-based recommendation algorithms and for the first time compare their performance on three distinct real datasets. We present recommendation topics that go beyond the mere question of which algorithm to use-such as the possible influence of recommendation on the evolution of systems that use it-and finally discuss open research directions and challenges.

    Skull base inverted papilloma (IP) is an unusual entity for many neurosurgeons. IP is renowned for its high rate of recurrence, its ability to cause local destruction, and its association with malignancy. This paper is a comprehensive review of the reports, studies, and reviews published in the current biomedical literature from 1947 to September 2010 and synthesize this information to focus on its potential invasion to the base of the skull and possible intradural extension. The objective is to familiarize the clinician with the different aspects of this unusual disease. The role of modern diagnostic tools in medical imaging in order to assess clearly the limits of the tumors and to enhance the efficiency and the safety in the choice of a surgical approach is pointed out. The treatment guidelines for IP have undergone a complex evolution that continues today. Radical excision of the tumour is technically difficult and often incomplete. Successful management of IP requires resection of the affected mucosa which could be achieved with open surgery, endoscopic, or combined approach. Radio and chemotherapy were used for certain indications. More optimally research would be a multicenter randomized trials with large size cohorts. PMID:23346418

    Magnesium has been suggested as a revolutionary biodegradable metal for biomedical applications. The corrosion of magnesium, however, is too rapid to match the rates of tissue healing and, additionally, exhibits the localized corrosion mechanism. Thus it is necessary to control the corrosion behaviors of magnesium for their practical use. This paper comprehensively reviews the research progress on the development of representative magnesium based alloys, including Mg-Ca, Mg-Sr, Mg-Zn and Mg-REE alloy systems as well as the bulk metallic glass. The influence of alloying element on their microstructures, mechanical properties and corrosion behaviors is summarized. The mechanical and corrosion properties of wrought magnesium alloys are also discussed in comparison with those of cast alloys. Furthermore, this review also covers research carried out in the field of the degradable coatings on magnesium alloys for biomedical applications. Calcium phosphate and biodegradable polymer coatings are discussed based on different preparation techniques used. We also compare the effect of different coatings on the corrosion behaviors of magnesium alloys substrate.

  3. Raman-based microarray readout: a review.

    For a quarter of a century, microarrays have been part of the routine analytical toolbox. Label-based fluorescence detection is still the commonest optical readout strategy. Since the 1990s, a continuously increasing number of label-based as well as label-free experiments on Raman-based microarray readout concepts have been reported. This review summarizes the possible concepts and methods and their advantages and challenges. A common label-based strategy is based on the binding of selective receptors as well as Raman reporter molecules to plasmonic nanoparticles in a sandwich immunoassay, which results in surface-enhanced Raman scattering signals of the reporter molecule. Alternatively, capture of the analytes can be performed by receptors on a microarray surface. Addition of plasmonic nanoparticles again leads to a surface-enhanced Raman scattering signal, not of a label but directly of the analyte. This approach is mostly proposed for bacteria and cell detection. However, although many promising readout strategies have been discussed in numerous publications, rarely have any of them made the step from proof of concept to a practical application, let alone routine use. Graphical Abstract Possible realization of a SERS (Surface-Enhanced Raman Scattering) system for microarray readout. PMID:26973235

    This study summarises research- and practice-based evidence on home-based chemotherapy, and explores existing delivery models. A three-pronged investigation was conducted consisting of a literature review and synthesis of 54 papers, a review of seven home-based chemotherapy programmes spanning four countries, and two case studies within the Canadian province of Ontario. The results support the provision of home-based chemotherapy as a safe and patient-centred alternative to hospital- and outpatient-based service. This paper consolidates information on home-based chemotherapy programmes including services and drugs offered, patient eligibility criteria, patient views and experiences, delivery structures and processes, and common challenges. Fourteen recommendations are also provided for improving the delivery of chemotherapy in patients' homes by prioritising patient-centredness, provider training and teamwork, safety and quality of care, and programme management. The results of this study can be used to inform the development of an evidence-informed model for the delivery of chemotherapy and related care, such as symptom management, in patients' homes.

    Background: Aphallia or penile agenesis is a rare malformation accompanying with no phallus. This anomaly is extremely rare with abnormality of urogenital system and psychological consequences. Its outbreak is estimated 1 out of 10-30 million births. Case: Reviewing 3 cases of male external genitalia agenesis, which associated with multiple anomalies of musculoskeletal, cardiovascular and genitourinary system. Conclusion: Aphallia has psychosocial consequences and a guarded prognosis. This study showed that if the kidney failure is due to its obstruction, these patients will be born in more favorable conditions and the future treatment measures will be directed to keep the external genitalia (male) through timely diagnosis and prenatal surgery and timely bladder drainage.

    Secondary oral cavity neoplasms are rare. We describe a case of an indurated, nonulcerating gingival lesion in a 59-year-old nonsmoking man with no family history of lung cancer. The lesion was the presenting symptom of metastatic lung adenocarcinoma. Reviewing the literature, we find that primary lung cancer among men is one of the most common cancers to metastasize to the oral cavity. Renal and cutaneous neoplasms are the next most common neoplasms to metastasize to the oral cavity. Furthermore, the gingiva, a tissue prone to inflammation, is noted to be a common site for secondary oral cavity neoplasms. This rare case highlights that metastases should influence the clinician’s differential of oral mucosal lesions. PMID:26824965

    Primary thyroid leiomyosarcoma (LMS) is an extremely rare soft tissue cancer; only 22 cases have been reported in the literature to date. In the current study, the case of an 83-year-old male patient who presented with a neck mass that had grown rapidly over the previous 3 months is reported. The patient underwent thyroid lobectomy twice and two cycles of immunotherapy for the treatment of primary thyroid LMS; however, he succumbed to the disease 5 months after the second surgery. An accurate diagnosis of primary thyroid LMS is difficult, as the disease is often misdiagnosed as anaplastic carcinoma, and requires the combined assessment of clinical, imaging and pathological data. Diagnosis of the current patient with primary thyroid LMS and a comprehensive review of the relevant literature are presented herein. PMID:27313727

    Alternating hemiplegia of childhood is an entity of uncertain etiology, with an incidence of about one case per million. This paroxysmal disease with progressive course is characterized by repeated episodes of hemiplegia that alternates its location and that may last from a few minutes to several days. These episodes are usually aborted during sleep. Paroxysmal eye movements, cognitive impairment and autonomic disorders, can also be seen. Due to its progressive course and bad prognosis, it turns out to be important for the generalist physician to be aware of this entity, thus facilitating an early diagnosis and avoiding empiric pharmacologic ineffective treatments. We present the case of a ten year-old girl with alternating hemiplegia of childhood, show imaging of this disease and make a brief review of the literature. PMID:23070192

    ABSTRACT Robinow syndrome is an extremely rare genetic disorder. Short-limbed dwarfism, abnormalities in the head, face, and external genitalia, as well as vertebral defects comprise its distinct features. This disorder exists in dominant and recessive patterns. Patients with the dominant pattern exhibit moderate symptoms. More physical characteristics and skeletal abnormalities characterize the recessive group. The syndrome is also known as Robinow-Silverman-Smith syndrome, Robinow dwarfism, fetal face, fetal face syndrome, fetal facies syndrome, acral dysostosis with facial and genital abnormalities, or mesomelic dwarfism-small genitalia syndrome. Covesdem syndrome was the name entitled for the recessive form previously. Here, we report a case of 8-year-old female with a autosomal recessive Robinow syndrome having skeletal and vertebral defects. How to cite this article: Soman C, Lingappa A.

    Hemangiomas are benign vascular tumors. They are the prerogative of the liver and skin. And genitourinary localizations are rare and have only been rarely reported in the prostat, bladder, ureter or the perineum. In the light of published cases, urethral hemangiomas are mostly found in males. Few cases of hemangioma in the female urethra were reported. We report a cavernous hemangioma of the urethra in a 61 years old patient who presented bleeding from the urethra and micturition disorders. Physical examination revealed a tumor 3 cm x 2 polyploid arising from the terminal urethra (urethral hemangioma). We performed surgical resection of the tumor, along with bladder drainage. The postoperative course was simple. We update through a review of the literature aspects of the diagnostic and therapeutic care of the urethral hemangioma. PMID:27231506
