    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.

    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.

    Hummel, Kevin; Gregory, Andrew; Desai, Neerav; Diamond, Alex

    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

    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.

    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.

    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

    2004-01-01

    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

    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.

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.

  4. Oesophageal tuberculosis: a review of eleven cases.

    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

    Leclercia adecarboxylata is usually isolated as a part of polymicrobial cultures in immunocompetent patients, and as a pure culture in immunocompromised persons. Although generally sensitive to most antibiotics, there are reports of resistant strains. Two case reports of L. adecarboxylata isolation in the lab in pure culture in immunocompetent persons are presented here, L. adecarboxylata being isolated from a vaginal swab in the first case and from a gluteal abscess in the second case. Both the isolates were sensitive to most of the antibiotics tested. PMID:25653951

    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

  18. 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.

    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

    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.

    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

    The authors report a case of digestive hemorrhage secondary to isolated duodenal varicosities, in a patient with ethylic cirrhosis. The diagnosis done through optical fibroscope was confirmed by arteriography. The evolution was unfavorable. Lesions were corroborated by autopsy. A review of the literature is done, about the 22 cases already published. With the help of these cases to authors stress the points that can lead to the good diagnosis and what therapeutical management should be done. PMID:6335644

    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

    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

    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.

    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.

    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.

    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

    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

    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.

    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.

    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

    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

    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

    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

  14. Human rabies in Hong Kong: a case review.

    PubMed

    Wong, T W; Chan, P K; Fung, K P

    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.

    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.

    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

  18. 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.

  19. 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

    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.

    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

    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

    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.

    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

  9. CABINS: Case-based interactive scheduler

    Miyashita, Kazuo; Sycara, Katia

    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.

    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

    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.

    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.

    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.

    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.

    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

    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

    Clostridia are anaerobic Gram-positive bacilli that can be isolated from the soil and the intestinal tract of humans. These microorganisms are recognized as the cause of devastating soft tissue infections, such as cellulitis, myositis, and gas gangrene. However, such bacteria may also be involved in various postoperative orthopedic infections, including prosthetic joint infection. We present three clinical cases of clostridial orthopedic infection and review the related medical literature. PMID:15078006

    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

    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.

    2000-06-01

    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

    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

    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.

    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.

    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

    Gastric bronchogenic cysts are rare lesions, first described in 1956, with only 34 cases reported in the literature to date. The present study described a case of bronchogenic cyst of the stomach in a 17-year-old female who presented with periodic epigastric pain. 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.

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

    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

    Waadernburg syndrome (WS) is an autosomal dominant disease clinically and genetically heterogeneous. It is characterized by non-progressive sensorineuronal hearing loss of variable degree and anomalous pigmentation (of the eyes, skin and stria vascularis of cochlear duct) caused by melanocytes absence. The syndrome is caused by mutations in genes that regulate the melanocytes differentiation from the neural crest during embriogenetic development. This study will review the literature on WS and explain more in detail the ocular findings in WS, while reporting new findings on two newly diagnosed cases. PMID:22555841

    We report a case of stress injury of the acromion related to golf practicing in a 40-year-old male. Fractures of the scapula are unusual, with stress injury of the acromion being even rarer. The probable mechanism would be a strong contraction of posterior fibers of the deltoid during golf swing. There are few published reports of similar injuries, and to our knowledge, this is the first to demonstrate its features by magnetic resonance imaging. A review of the literature is also presented.

    Objective. Primary hepatic lymphoma is a rare disease. And the clinical manifestations of this disease are nonspecific. The objective of this paper is to improve clinicians' understanding of this disease. Methods. We analyzed the clinical characteristics of a case of primary hepatic lymphoma in association with hepatitis B virus infection and reviewed the literature. Conclusion. The clinical manifestations of primary hepatic lymphoma are nonspecific. And it is easily misdiagnosed. Postoperative radiotherapy of patients with early stage was previously speculated to achieve favorable improvement. The application of targeted therapeutic drugs, chemotherapy, or combined local radiotherapy has become the first-line treatment strategy. PMID:27403354

    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.

    Endometrial ossification is a rare endometrial pathology. Its predisposing factors include history of uterine curettage to metabolic abnormalities. It usually presents in patients with secondary infertility and history of first trimester pregnancy loss, accompanied by severe dysmenorrhea and dyspareunia. The diagnosis is suspected by OB-GYN history and USG findings, therapeutic strategies range from D&C to hysterectomy, we propose diagnosis and management by hysteroscopy in order to preserve future fertility and minimize uterine damage.

    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.

    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.

    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.

  1. Skull Base Inverted Papilloma: A Comprehensive Review

    Wassef, Shafik N.; Batra, Pete S.; Barnett, Samuel

    2012-01-01

    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.

    2016-07-01

    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.

    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

    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.

    Moxibustion is a traditional medical treatment originating in China. It involves using the heat of burning moxa to stimulate acupoints. It is considered safe and effective and is widely used throughout the world. The increasing use of moxibustion has drawn attention to the procedure's adverse events (AEs). This review covers a total of 64 cases of AEs associated with moxibustion in 24 articles, reported in six countries. Some evidence of the risks of moxibustion has been found in these cases. AEs include allergies, burns, infection, coughing, nausea, vomiting, fetal distress, premature birth, basal cell carcinoma (BCC), ectropion, hyperpigmentation, and even death. The position, duration, distance between moxa and skin, proficiency of the practitioners, conditions of the patients, presence of smoke, and even the environment of treatment can affect the safety of moxibustion. Improving practitioner skill and regulating operations may reduce the incidence of adverse reactions and improve the security of moxibustion. PMID:24976851

    A mesonephric adenocarcinoma of the cervix is a very rare tumor deriving from remnants of the mesonephric duct. Differential diagnosis from other cervical carcinomas is difficult and little is known regarding its biological behavior, prognosis, and the optimal management strategy. We present a case of a mesonephric adenocarcinoma of the cervix with a comprehensive review of the existing literature. In this case a 66-year-old woman presented with postmenopausal vaginal bleeding. She was diagnosed with a FIGO stage IIB mesonephric adenocarcinoma of the cervix and treated with neoadjuvant chemoradiotherapy and a Wertheim hysterectomy. The recovery from surgery was uneventful and the patient remains with no evidence of disease with 2 years of follow-up. PMID:27354991

    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

    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.

    SUMMARY - Post-intubation tracheal injury is a rare and potentially fatal complication. The most common causes are overinflation ofendotracheal tube cuffs and multiple intubation attempts in emergency cases. The diagnosis is based on clinical and radiological suspicion of tracheal injury confirmed by fiberoptic bronchoscopy. Decision between conservative and surgical management of the injury depends on clinical presentation (respiratory instability, concomitant diseases), lesion characteristics (lesion site, size, and number), and time elapsed from injury to diagnosis. We present three cases ofpost-intubation tracheal injury. In two cases, the patients were treated conservatively; in the third case, the patient died from asphyxia caused by thrombus occlusion of the trachea after a longitudinal tracheal lesion. Pre-anesthetic examination did not indicate any possibility of difficult intubation in any of the patients; however, in one of the patients admitted through the emergency department, emergency intubation was performed.

    Spinal epidural hematoma is a rare neurosurgical emergency in respect of motor and sensory loss. Identifiable reasons for spontaneous hemorrhage are vascular malformations and hemophilias. We presented a case of spontaneous epidural hematoma in an 18-year-old female patient who had motor and sensory deficits that had been present for 1 day. On MRI, there was spinal epidural hematoma posterior to the T2-T3 spinal cord. The hematoma was evacuated with T2 hemilaminectomy and T3 laminectomy. Patient recovered immediately after the surgery. Literature review depicted 112 pediatric cases (including the presented one) of spinal epidural hematoma. The female/male ratio is 1.1:2. Average age at presentation is 7.09 years. Clinical presentations include loss of strength, sensory disturbance, bowel and bladder disturbances, neck pain, back pain, leg pain, abdominal pain, meningismus, respiratory difficulty, irritability, gait instability, and torticollis. Most common spinal level was cervicothoracic spine. Time interval from symptom onset to clinical diagnosis varied from immediate to 18 months. Spinal epidural hematoma happened spontaneously in 71.8 % of the cases, and hemophilia was the leading disorder (58 %) in the cases with a definable disorder. Partial or complete recovery is possible after surgical interventions and factor supplementations. PMID:26033378

    Apotemnophilia or body integrity identity disorder (BIID) denotes a syndrome in which a person is preoccupied with the desire to amputate a healthy limb. In this report, we review the available case reports in the literature in order to enhance psychiatrists' and physicians' comprehension of this disorder. A search for the case reports available via MEDLINE was done since the first case report published by Money et al in 1977 till May 2011, using the following terms: apotemnophilia, self-demand amputation, body integrity identity disorder, and BIID. In all, 14 case reports were found relevant to our search. The desire to amputate one's healthy limb seems to be related to a major disturbance in the person's perception of one's own identity, where limb amputation can relieve temporarily the patient's feeling of distress without necessarily and uniformly adjusting the patient's own identity misperception. More investigations are needed in this domain in order to develop noninvasive treatment strategies that approach this aspect of the patient's distress within a globalist perspective. In addition, the health professionals' awareness regarding this disorder is required to ensure professional management of patients' suffering. PMID:23089967

    Many medicines available over the counter from pharmacies are known to have abuse potential, including diphenhydramine (DPH), an antihistamine with antimuscarinic properties used for the treatment of insomnia. We present a brief review of the literature describing DPH abuse, and report the case of GF, a 56 year old woman who was admitted to an inpatient addictions unit for detoxification from DPH. A literature search revealed five case reports of DPH abuse including a total of six patients, published between 1986 and 2001. All reported cases exhibited features of DSM-IV criteria for substance dependence, and there was an apparent link with antipsychotic usage. GF was treated with antipsychotics, and was using up to thirty 50 mg DPH tablets each day. She described feeling 'good and calm' and 'it stopped the tremors'. GF tolerated a gradual dose reduction schedule, and completed the detoxification programme relatively comfortably. She was discharged from the inpatient detoxification unit as planned, and had not relapsed at six months. The described case report highlights the importance of enquiring about non prescribed medication when taking a drug history. Similarly community pharmacists and GPs should be vigilant to excessive requests for DPH, particularly in patients with a psychotic illness. PMID:18308811

    Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla. The patient reported that dental extractions in this region had been performed over a period of nearly 23 years. The panoramic radiograph demonstrated an opacity in the right maxillary sinus, which presented a spongiform aspect, irregularly shaped radiopaque image, as well as a rupture of the maxillary sinus's lower cortical layer. A surgical excision was performed, and the histopathological diagnosis was of gossypiboma. Six similar cases have also reported of gossypiboma in the oral region; however, calcification was only identified in the present case report. The patient is currently undergoing follow-up and has presented no complaints of pain or recurrence. Key words:Gossypiboma, textiloma, muslinoma, gauzoma, oral region. PMID:25593672

    2016-01-01

    Objectives As the craniofacial and neck regions are prime areas of injury in bear attacks, the careful management of soft and hard tissue injuries and selection of reconstructive options is of the utmost importance. This study will review the incidence and patterns of bear mauling in eastern India reported to our department and the various modalities used for their treatment over a period of 7 years. It also documents the risks of infection in bear mauling cases and the complications that have occurred. Materials and Methods Twenty cases were treated over the study period. Cases were evaluated for soft and hard tissue injuries including tissue loss and corresponding management in the craniofacial region. Cases were also evaluated for other associated injuries, organ damage and related complications. Results Various modalities of treatment were used for the management of victims, ranging from simple primary repairs to free tissue transfers. Simple primary repairs were done in 75% of cases, while the management of the injured victims required reconstruction by local, regional or distant flaps in 25%. Free tissue transfers were performed in 15% of cases, and no cases of wound infection were detected in the course of treatment. Conclusion Knowledge of various reconstructive techniques is essential for managing maxillofacial injuries in bear mauling cases. Modern reconstructive procedures like free tissue transfer are reliable options for reconstruction with minimal co-morbidity and dramatic improvement in treatment outcomes. PMID:26904490

    Graphitic carbon nitride (g-C(3)N(4)), as an intriguing earth-abundant visible light photocatalyst, possesses a unique two-dimensional structure, excellent chemical stability and tunable electronic structure. Pure g-C(3)N(4) suffers from rapid recombination of photo-generated electron-hole pairs resulting in low photocatalytic activity. Because of the unique electronic structure, the g-C(3)N(4) could act as an eminent candidate for coupling with various functional materials to enhance the performance. According to the discrepancies in the photocatalytic mechanism and process, six primary systems of g-C(3)N(4)-based nanocomposites can be classified and summarized: namely, the g-C(3)N(4) based metal-free heterojunction, the g-C(3)N(4)/single metal oxide (metal sulfide) heterojunction, g-C(3)N(4)/composite oxide, the g-C(3)N(4)/halide heterojunction, g-C(3)N(4)/noble metal heterostructures, and the g-C(3)N(4) based complex system. Apart from the depiction of the fabrication methods, heterojunction structure and multifunctional application of the g-C(3)N(4)-based nanocomposites, we emphasize and elaborate on the underlying mechanisms in the photocatalytic activity enhancement of g-C(3)N(4)-based nanocomposites. The unique functions of the p-n junction (semiconductor/semiconductor heterostructures), the Schottky junction (metal/semiconductor heterostructures), the surface plasmon resonance (SPR) effect, photosensitization, superconductivity, etc. are utilized in the photocatalytic processes. Furthermore, the enhanced performance of g-C(3)N(4)-based nanocomposites has been widely employed in environmental and energetic applications such as photocatalytic degradation of pollutants, photocatalytic hydrogen generation, carbon dioxide reduction, disinfection, and supercapacitors. This critical review ends with a summary and some perspectives on the challenges and new directions in exploring g-C(3)N(4)-based advanced nanomaterials. PMID:25407808

A 58-year old woman, residing in Hadong-gun, Gyeongsangnam-do, came to Gyeongsang National University Hospital (GNUH) complaining of foreign body sensation and itching of the right eye in March 2000. Total 6 adult nematodes of Thelazia callipaeda (2 males and 4 females) were detected in her right eye. A 80-year old man, residing in Jinju-si, Gyeongsangnam-do, came to GNUH complaining of foreign body sensation, itching, and pain of the right eye in December 2007. A total of 5 worms (4 females and 1 degenerated) were removed from his right eye. We analyzed characteristics of the total 39 Korean HT cases reported to date, including the present 2 cases. Most of the cases (71.8%) occurred in Seoul and Gyeonggi-do before 2000, and 21 cases (53.8%) were males and 18 (46.2%) were females. The prevalence was higher in younger ages below 30 years (48.7%) than 31-60 years (41.0%) and over 61 years (10.3%). The seasonal prevalence showed a higher incidence in autumn (43.6%) than in other seasons. Most of the cases (94.9%) were conjunctival sac infections and only 2 (5.1%) were intraocular cases. The present 2 HT cases are the first reported cases in Gyeongsangnam-do. Some characteristics of Korean HT cases were analyzed. PMID:22072826

    The history of histology indicates that there have been significant changes in the techniques used for histological staining through chemical, molecular biology assays and immunological techniques, collectively referred to as histochemistry. Early histologists used the readily available chemicals to prepare tissues for microscopic studies; these laboratory chemicals were potassium dichromate, alcohol and the mercuric chloride to harden cellular tissues. Staining techniques used were carmine, silver nitrate, Giemsa, Trichrome Stains, Gram Stain and Hematoxylin among others. The purpose of this research was to assess past and current literature reviews, as well as case studies, with the aim of informing ways in which histological stains have been improved in the modern age. Results from the literature review has indicated that there has been an improvement in histopathology and histotechnology in stains used. There has been a rising need for efficient, accurate and less complex staining procedures. Many stain procedures are still in use today, and many others have been replaced with new immunostaining, molecular, non-culture and other advanced staining techniques. Some staining methods have been abandoned because the chemicals required have been medically proven to be toxic. The case studies indicated that in modern histology a combination of different stain techniques are used to enhance the effectiveness of the staining process. Currently, improved histological stains, have been modified and combined with other stains to improve their effectiveness. PMID:26493433

    Bilateral patellar tendon ruptures are rare. The majority of case reports describing bilateral patellar tendon ruptures have occurred in patients with predisposing factors to tendinopathy. We describe a case of bilateral patellar tendon rupture sustained following minimal trauma by a patient with no systemic disease or history of steroid use. Due to the rarity of this injury, clinical suspicion is low. It is reported that 38% of patellar tendon ruptures are misdiagnosed initially. Therefore careful history taking and physical examination is integral in ensuring a diagnosis is achieved for early primary repair. We discuss the aetiology of spontaneous tendon rupture and report a literature review of bilateral patellar tendon ruptures. PMID:27200200

    Objectives To report experience with transverse sacral fracture, an uncommon injury frequently associated with neurologic deficit, and to perform a meta-analysis of the literature in order to define the role of decompression for the management of sacral fractures. Design A review of 7 cases. Setting A university-affiliated tertiary care centre. Patients Seven patients with transverse fractures of the sacrum. The mean follow-up was 13 months. Interventions A review of the clinical data and a search of the literature for studies that reported on 4 or more patients with a transverse sacral fracture. Main outcome measures Mechanism of injury, type of neurologic deficit and its management. Results The most common mechanism in the 7 study patients was a fall from a height. Six patients had neurologic deficits, mostly in the form of bowel or bladder disturbance. Five of these were treated with surgical decompression, and 4 of them had an improvement in neurologic function. The 7 original studies from the literature dealt with a total of 55 patients. As in the study patients, falls from a height and motor vehicle accidents predominated as the mechanisms of injury. In contrast to patients in this study, 20 of 48 patients in the literature review with neurologic deficits were treated conservatively. Conclusions The outcomes in this study are similar to those reported in the literature. The place of surgical decompression for patients with neurologic deficit cannot be clearly determined from the evidence currently available. PMID:11603749

    Sarcoma of the breast is a rare condition, with one possible meaning of relapse ad metastastasize, and behaves biologically as a stromal tumor. Surgery is the first choise and mastectomy is the best procedure adopted in these tumors. The aim of our study was to assess diagnostic and treatment options for PT, based on a review of the literature and our experience with a case of breast sarcoma arising from a phyllodes tumor.

    A 59-year-old Caucasian male presented with progressive dyspnea, arthralgias and fever for three days. A diastolic regurgitation murmur was detected in the aortic area. A transesophageal echocardiograph showed several vegetations and severe aortic regurgitation. Blood cultures yielded Neisseria gonorrhoeae beta-lactamase negative. The patient had not noticed any urogenital discomfort or urethral discharge. The patient successfully underwent surgery for septal abscess debridement. The patient received ceftriaxone 2 g bid for eight weeks and the clinical follow-up was uneventful. The review of the literature revealed a total of the 38 additional cases reported between 1980 and the present. The majority of the patients were young, male and with native valve involvement. There has been a clear tendency for left-sided valve involvement (especially in the aortic valve). All valve cultures were reported negative despite, in most cases, the marked tissue destruction. Polymerase chain reaction was performed in two patients and positive results were shown in both. Cultures of exudates from other locations were negative in most cases. One striking fact is the high proportion of patients who underwent surgery (72 %). Information regarding antibiotic sensitivity was available in 28 cases, with penicillin resistance reported in six patients (21 %) and intermediate sensitivity in four patients (14 %). Resistance to ciprofloxacin was reported in two cases (7 %). A rapid increase and distribution of isolates resistant to third generation cephalosporins have been recently detected. The mortality is high, particularly taking into account that most were young patients who had not presented previous heart disease. PMID:24163221

    The anterior opercular or biopercular syndrome is a cortical pseudobulbar palsy due to bilateral lesions of the anterior brain operculum. It is characterized by preservation of reflex function and automatic activity, without mental impairment. Two cases are reported herein and the relevant literature reviewed. The first case was a 73-year-old female with a history of a stroke occurring seven years previously, without sequelae in the interim. She presented with sudden loss of consciousness. The neurological examination showed a right facial central palsy and anarthria, with reflex acts such as smiling, blinking and yawning, not elicited by commands; she also had a right hemiparesis and walking impairment. A brain CT scan showed an old ischemic infarction in the region of the right medial cerebral artery. Because the right motor involvement did not correlate with the findings of the initial CT scan, another CT scan two days later showed an acute brain infarction in the vicinity of the left medial cerebral artery. The second case was an 8-year-old girl with mental retardation and impairment of verbal development, caused by of biopercular pachygyria. Facio-pharyngo-glosso-masticatory diplegia and volitional selective palsy of the oro-facial muscles was seen in both patients. The neuropsychological assessment showed cognitive, emotional and social interaction impairment in both cases -as part of the frontal convexity syndrome in the first case and of mental retardation in the second. The two patients had difficulty in mastication and swallowing. The prognosis for recovery of verbal capacity is poor, although generally most patients recover the ability to swallow. PMID:18719720

    Pharmacokinetics and pharmacodynamics can provide a useful modeling framework for predicting drug activity and can serve as a basis for dose optimization. Determining a suitable biomarker or surrogate measure of drug effect for pharmacodynamic models can be challenging. The electroencephalograph is a widely-available and non-invasive tool for recording brain-wave activity simultaneously from multiple brain regions. Certain drug classes (such as drugs that act on the central nervous system) also generate a reproducible electroencephalogram (EEG) effect. Characterization of such a drug-induced EEG effect can produce pharmacokinetic/pharmacodynamic models useful for titrating drug levels and expediting development of chemically-similar drug analogs. This paper reviews the relevant concepts involved in pharmacokinetic/pharmacodynamic modeling using EEG-based pharmacodynamic measures. In addition, examples of such models for various drugs are organized by drug activity as well as chemical structure and presented. PMID:22373830

    Once referred to as "flyer's toothache," barodontalgia is defined as tooth pain occurring with changes in ambient pressure. It usually occurs in people who fly or dive. It can develop in conjunction with sinusitis, and in teeth experiencing pulpitis after restorative treatment, new and recurrent caries, intra-treatment endodontic symptoms, dental and periodontal cysts, or abscesses. Although the causal process of barodontalgia is not well understood, it may be related to pulpal hyperemia, or to gases that are trapped in the teeth following incomplete root canal treatment. Patients who are frequently exposed to changes in ambient pressure should be encouraged to follow good oral health practices, attend regularly-scheduled dental recall examinations and accept the timely completion of restorative treatment to minimize the possibility of developing barodontalgia. By employing a classification system to document cases of barodontalgia, dentists will be better prepared to provide appropriate and successful treatment. Seven case reports of barodontalgia are presented and compared to previously documented cases. The author also reviews the reasons why military flyers are more likely to develop barodontalgia than others, although the passengers and crews of commercial airliners may also suffer from this condition.

    Tuberculosis (TB) is still a major health problem worldwide. We present a rare case of an immuno-competent patient with perianal TB. A 38-year-old man visited a clinic with pain, swelling, and redness in the perineum. He had been persistently coughing for the past 6 mo. The abscess had formed a fistula to the perianal region, indicating perianal abscess. Mycobacterium tuberculosis was found in sputum and perianal abscess. Surgical drainage was performed, and oral anti-tuberculous drugs were administered for 6 mo. The patient's clinical course was favorable. On review of the literature on 58 cases of perianal TB, we found that the duration of persistent perianal lesion was much longer in patients without active pulmonary TB (APTB) than in those with APTB (66.4 mo vs 8.3 mo; confidence interval, 0.0760-0.9620, P = 0.0380). Thus, in cases of non-healing or recurrent perianal lesions, TB should be considered. PMID:26380834

    Complex anatomical relation of the duodenum, pancreas, biliary tract, and major vessels plays to obscure pancreaticoduodenal injuries. Causes of pancreaticoduodenal injuries are blunt trauma (traffic accidents, sport injuries) in 25 % of cases and penetrating abdominal injuries (stab wounds and firearm injuries) in 75 % of cases. Duodenal injuries are reported to occur in 0.5 to 5 % of all abdominal trauma cases and are observed in 11 % of abdominal firearm wounds, 1.6 % of abdominal stab wounds, and 6 % of blunt trauma. Retroperitoneal and deep abdominal localization of duodenum as an organ contribute to the difficulty in diagnosis and treatment. There are three important major points regarding treatment of duodenal injuries: (1) operation timing and decision, (2) Intraoperative detection, and (3) post-operative care. Therefore, it is difficult to diagnose and treat duodenal trauma. We would like to present a 21-year-old male patient with pancreaticoduodenal injury who presented to our emergency service after firearm injury to his abdomen and discuss his treatment with a short review of related literature.

    Rhabdomyosarcoma (RMS) that primarily occurs in the testes is particularly rare, with only retrospective studies and sporadic cases reported in the literature. The present study describes the case of a large, primary intratesticular RMS (ITRMS) that was treated with a radical inguinal orchiectomy (RIO) and a regimen of chemotherapy. The study also presents a review of the literature regarding primary ITRMSs, aiming to elucidate the clinical characteristics and optimal treatment of the disease. A 14-year-old male presented with a 1-year history of a slow-growing, painless, left scrotal mass. Magnetic resonance imaging identified a mass in the left scrotum with mixed signal intensity; no abnormal signals were identified in the right testicle and retroperitoneal lymph node. An X-ray of the chest demonstrated no evidence of metastasis. Subsequent to this, a left RIO was performed. Histopathological and immunohistochemical examination confirmed the final diagnosis of embryonal ITRMS. At 21 days post-surgery, an 18F-fluorodeoxyglucose-positron emission tomography-computed tomography (FDG-PET-CT) scan identified widespread metastatic lesions in the lungs, local lymph nodes and bones, presenting as increased glucose metabolism nodules. Subsequently, the patient received six sequential cycles of adjunct chemotherapy. The patient is alive with disease in October 2015. The case described is noteworthy as it is an example of ITRMS, in which the patient received successful treatment. However, multidisciplinary treatment may further improve the outcome of the disease.

    Background and Importance Chondroblastoma is a benign primary bone tumor that typically develops in the epiphyses of long bones. Chondroblastoma of the craniofacial skeleton is extremely rare, with most cases occurring in the squamosal portion of the temporal bone. In this report, we describe the first case of chondroblastoma of the clivus presenting with cranial neuropathy that was treated with endoscopic endonasal resection. We review the literature on craniofacial chondroblastomas with particular emphasis on extratemporal lesions. Case Presentation A 27-year-old woman presented with severe headache, left facial dysesthesias, and diplopia. Physical examination revealed hypesthesia in the left maxillary nerve dermatome, and complete left abducens nerve palsy. Imaging demonstrated an expansile intraosseous mass originating in the upper clivus with extension superiorly into the sella turcica and laterally to involve the medial wall of the left cavernous sinus. The tumor was completely resected via an endoscopic endonasal approach, with postoperative improvement in lateral gaze palsy. Histopathology was consistent with chondroblastoma. Conclusion Chondroblastoma is a rare tumor of the craniofacial skeleton that should be included in the differential diagnosis of an osteolytic lesion of the clivus. Complete surgical resection remains the mainstay of treatment. PMID:26623238

    Urinothorax, the presence of urine in the pleural space, is a rare cause of pleural effusion, usually associated with obstructive uropathy, or urinary trauma. We present the case of a 3 year-old boy and a systematic review of the literature of the 44 cases encountered. After resection of a Wilm's tumour in the right kidney our patient presented acute respiratory distress associated with radiographically confirmed pleural effusion. With the initial diagnosis of pneumonia or malignant pleural effusion, a closed thoracotomy was performed. The liquid obtained suggested urine, which was confirmed by the laboratory. Cystoscopy with retrograde pyelography detected a fistula on the posterior wall of the right kidney. The report of cases worldwide is low, probably due to its low incidence but also to underdiagnosis. Respiratory symptoms are not always present and urological symptoms usually predominate. Diagnosis requires a high degree of clinical suspicion and is confirmed by the main biochemical marker: The ratio >1.0 pleural fluid creatinine and creatinine serum. PMID:26834411

    Summary Introduction: Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare. Aim: This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic. Case report: A 51-year-old woman presented at our tertiary university hospital with a 6-month history of progressive nasal obstruction, predominantly to the right side, and self-limiting epistaxis. Examination revealed a large pale-reddish tumor within the right nasal cavity. Anatomopathological analysis showed features consistent with a plasmacytoma diagnosis, which was subsequently confirmed by immunohistochemical techniques. Further assessment revealed the solitary nature of the condition, consistent with extramedullary plasmacytoma. Radiotherapy was initiated, which led to partial regression of the symptoms. The tumor was surgically removed by using a mid-facial degloving approach. The patient evolved with a naso-oral fistula and underwent 3 corrective surgeries. No evidence of associated systemic disease was found after 5 years of follow-up. Conclusions: This case report, which describes a rare tumor of the nasal cavity, is expected to improve the recognition and referral of this condition by ear, nose, and throat (ENT) specialists for multidisciplinary management and long-term follow-up.

    2015-01-01

    An inflammatory myofibroblastic tumor (IMT) is an immunohistochemically diverse entity demonstrating neoplastic and nonneoplastic qualities. Although IMTs can arise in any area of the body, lesions arising in certain sites, namely, the nasal cavity, paranasal sinuses, and pterygopalatine fossa, demonstrate a heightened neoplastic and invasive potential. Despite case specific complete tumor regression and disease remission in response to pharmacotherapeutics, a subset of IMTs remain resistant to all forms of therapy. We present such a case, a 34-year-old female patient, with a highly resistant, maxillary sinus IMT. Her refractory, ALK-1 negative IMT has not responded well to novel therapies reported in current literature. This case suggests the role of zonal expressivity within a single lesion as a probable mechanism for its highly resistant nature and should promote determination of each IMT's cytogenetic profile to provide more effective targeted therapy. Paper includes a literature review of all maxillary sinus IMTs from 1985 to 2014 along with their immunohistochemical staining, treatments, and outcomes. PMID:25763286

    Background Lymphatic malformation (LM) is a form of congenital vascular malformation with a low incidence. Although LM has been studied, no consensus has emerged regarding its cause or treatment. Methods In this study, we retrospectively evaluated 40 patients who visited our vascular anomalies center for the treatment of cervicofacial LM, which is a common manifestation of LM. The medical records of patients over a period of 12 years were reviewed and analyzed for commonalities regarding the diagnosis and the results of treatment. Results Suspected cervicofacial LM was confirmed through imaging studies. No difference in incidence was observed according to sex, and 73% of patients first presented with symptoms before the age of two years. The left side and the V2–V3 area were most commonly affected. No significant differences in incidence were observed among the macrocystic, microcystic, and combined types of LM. A total of 28 out of 36 patients received sclerotherapy as the first choice of treatment, regardless of the type of lesion. Complete resolution was achieved in only 25% of patients. Conclusions LM is important to confirm the diagnosis early and to choose an appropriate treatment strategy according to the stage of the disease and each individual patient's symptoms. When treatment is delayed or an incorrect treatment is administered, patient discomfort increases as the lesion gradually spreads. Therefore, more so than is the case for most other diseases, a team approach on a case-by-case basis is important for the accurate and appropriate treatment of LM. PMID:26848440

    PubMed Central

    2010-01-01

    Rhinitis is characterized by rhinorrhea, sneezing, nasal congestion, nasal itch and/or postnasal drip. Often the first step in arriving at a diagnosis is to exclude or diagnose sensitivity to inhalant allergens. Non-allergic rhinitis (NAR) comprises multiple distinct conditions that may even co-exist with allergic rhinitis (AR). They may differ in their presentation and treatment. As well, the pathogenesis of NAR is not clearly elucidated and likely varied. There are many conditions that can have similar presentations to NAR or AR, including nasal polyps, anatomical/mechanical factors, autoimmune diseases, metabolic conditions, genetic conditions and immunodeficiency. Here we present a case of a rare condition initially diagnosed and treated as typical allergic rhinitis vs. vasomotor rhinitis, but found to be something much more serious. This case illustrates the importance of maintaining an appropriate differential diagnosis for a complaint routinely seen as mundane. The case presentation is followed by a review of the potential causes and pathogenesis of NAR. PMID:20181075

    Keratoameloblastoma is a rare subtype of ameloblastoma. It tends to have a poor prognosis, and therefore a careful diagnosis based on imaging is important in planning appropriate surgical treatment for this distinctive type of ameloblastoma. A unique feature of keratoameloblastoma is atypical calcification inside the mass, such as a ground-glass appearance, internal calcification, or a mixed radiolucent and radiopaque pattern. Because of its poor prognosis and the likelihood of frequent recurrences, surgical resection is considered the treatment of choice. This study reports a new case of keratoameloblastoma with special emphasis on its radiologic features and reviews previously reported cases of keratoameloblastoma. PMID:26337217

    Paroxysmal cold hemoglobinuria (PCH) is an acquired hemolytic anemia caused by immunoglobulin G (IgG) antibodies that sensitize red blood cells (RBCs) at cold temperatures by fixing complement to the RBCs causing intravascular hemolysis on rewarming. PCH usually appears in young children as recurrent high fevers, chills, and passage of red-brown urine. The diagnostic test for PCH is the Donath-Landsteiner test, an in vitro assay for biphasic hemolysis. Herein, we present 2 cases of PCH that occurred within 12 months of each other. We quickly diagnosed the second case and treated the patient successfully, in part due to our recognition of its characteristics based on the first case. PCH is a hemolytic anemia for which there is a specific diagnostic test; the timely recognition of this entity by physicians and laboratory staff will allow prompt, supportive therapy and will raise the odds of quick resolution of hemolysis.

    The unicompartimental knee prosthesis known as "Oxford" is a non constraint prosthesis, entrusting the whole of its stability to an intact ligamentary apparatus. Where the support surfaces of most prostheses remain limited, even punctiform, the originality of the Goodfellow prosthesis lies in the fact that the prosthetic condyle, whatever the flexion angle is, leans against a mobile prosthetic meniscus with spheric superior concavity of the same radius as the condylian radius, which increases considerably the prosthetic leaning surfaces and therefore lessens the pressure constraints. The superior surface, concave, of this prosthetic meniscus takes charge of the rolling, where the inferior plane surface realizes the gliding on the metallic tibial plate. The total conformity of the components minimizes the forces of friction.Between July 1988 and March 1993, 24 patients underwent the placing of UCP. Three patients died and 2 were lost of sight. 19 patients could be seen again or checked, corresponding of 21 operated knees. Two knees benefited from the start from UCP (medial and lateral) and 2 knees had a UCP in the first instance and then a second UCP in the compartment left safe primarily. For the 21 UCP, there are 16 medial and 3 lateral. Our mean drawback is of 3 years and 3 months, all the drawbacks being superior to 1 year and 4 months. The mean age is of 64 years. There were 17 female and 2 male patients. The mean weight is of nearly 80 kg (79,8) and nearly 52% of the operated patients have an important overweight (Body Mass Index superior to 30).

    The past decade has seen the emergence of programs that make use of large knowledge bases to assist physicians in diagnosis within the general field of internal medicine. One such program, Internist-I, contains knowledge about over 600 diseases, covering a significant proportion of internal medicine. This paper describes the process of converting a subset of this knowledge base--in the area of cardiovascular diseases--into a probabilistic format, and the use of this resulting knowledge base to teach medical diagnostic knowledge. The system (called KBSimulator--for Knowledge-Based patient Simulator) generates simulated patient cases and uses these cases as a focal point from which to teach medical knowledge. It interacts with the student in a mixed-initiative fashion, presenting patients for the student to diagnose, and allowing the student to obtain further information on his/her own initiative in the context of that patient case. The system scores the student, and uses these scores to form a rudimentary model of the student. This resulting model of the student is then used to direct the generation of subsequent patient cases. This project demonstrates the feasibility of building an intelligent, flexible instructional system that uses a knowledge base constructed primarily for medical diagnosis.

    Introduction: Congenital trigger thumb is an uncommon anomaly of children. Its management is controversial, ranging from observation to extensive surgical release. We report a case of delayed presentation of bilateral trigger thumb along with a brief review of past literature. Case Report: A six year old girl presented with fixed flexion deformity of interphalangeal joints of both thumbs and Notta’s nodules. It is diagnosed as trigger thumb and release of bilateral A1pulleys is done. But we found another constricting annular pulley just distal to A1. Only after splitting the distal pulley, we could get complete extension of interphalangeal joints. At two years follow-up, the child is free of complications. Conclusion: Splitting of A1 pulley alone may not be sufficient in few cases of trigger thumb which may require distal release too

    Cystic adventitial disease (CAD) is a rare vascular disease that causes a localized stenosis or occlusion in absence of alterations of blood vessels in other sites of the body. CAD is predominantly located to the popliteal artery, although cases have been described involving other arteries. Typically it affects young men with minimal cardiovascular risk factors, presenting a short history of progressive claudication. Imaging is based on US, CTA and MRA. Suspected diagnosis is confirmed at the time of the surgery. We report two cases of CAD involving the popliteal artery. In the first case a 59 year-old man was treated by resection of the popliteal artery and a reversed saphenous vein was used to restore circulation. In the second case a 53 year-old man was treated by resection of the popliteal artery and a cryo-preserved arterial graft was used to restore circulation. We also made a review of the literature on this subject. PMID:25419589

    Background Desmoid tumor of the breast is very rare and locally aggressive but has no distant metastasis. Bilateral lesions are extremely rare, found in only 4% of patients. Two cases of bilateral desmoid tumor of the breast are reported. The clinical presentation, diagnosis, imaging, treatment, and follow-up outcomes of recurrence as well as a brief literature review are provided. Case reports Case 1 is a 31-year-old woman who presented with nipple retraction. An ultrasound revealed BIRAD V in both breasts. She underwent a bilateral excisional biopsy under ultrasound mark with the pathology result of extra-abdominal desmoid tumor in both breasts. The patient had a bilateral mastectomy with silicone implantation due to the involved margins by excision. She remained tumor free after 7-year follow-up. Case 2 is a 28-year-old woman who presented with a lump on her right breast that she had discovered ~2 months earlier. An ultrasound showed a spiculated mass in the right breast and some circumscribed hypoechoic masses in both breasts. A bilateral breast excision was done. The pathology result was an extra-abdominal desmoid tumor. She had recurrence on both sides and underwent a mastectomy and silicone implantation. The tumor has not recurred after 1-year follow-up. Conclusion Imaging cannot distinguish between benign breast lesions and malignancy. Pathology results are helpful in making a definitive diagnosis. Given that the desmoid tumor is locally aggressive, a local excision with clear margins is recommended. Chemotherapy and hormonal treatment are controversial. PMID:27578999

    Introduction: Tracheobronchopathia osteochondroplastica (TO) is a rare disorder involving the lumen of the trachea-bronchial tree and characterized by multiple sub-mucosal osseous and cartilaginous nodules in the trachea and bronchus, sparing the posterior wall. We here report two cases of patients with tracheobronchopathia osteochondroplastica and review the relevant literature briefly. Case presentation: Case 1 was a 64-year-old woman with a history of Chronic Obstructive Pulmonary Disease (COPD) who presented with frequent non-productive cough for 2 years. Chest computed tomography (CT) showed signs consistent with COPD and evident irregular narrowing of the tracheal and both main bronchial lumen caused by calcific foci. Fibre optic bronchoscope (FOB) was performed and showed dozens of sub-mucosal nodules protruding into the lumen of lower half of the trachea and both main bronchi. Histopathological exam demonstrated sub-mucosal ossification and cartilage in the sample. Her follow-up has been uneventful for 3 years. Case 2 was a 37-year-old man presented with hoarseness, exertional dyspnea, and intermittent dry cough for about 3 years. Chest CT scans showed irregular nodules around the entire circumference of the trachea extending from sub-glottic region to lower trachea. FOB showed glottic stenosis and diffused sub-mucosal calcified nodules protruding from the antero-lateral portion of the trachea in the subglottic region. Over the following 12 months, his disease is stable. Conclusions: TO is a rare, benign disease with slow progression, clinicians should be aware of TO and should consider it in patients with chronic cough, recurrent respiratory infection and evolving exertional dyspnea.

    Odontogenic keratocysts (OKCs) may occur in two different forms, either as solitary (nonsyndromic OKCs) or as multiple OKCs (syndromic OKCs). Multiple OKCs usually occur as one of the findings in Gorlin–Goltz syndrome with other features such as skin carcinomas and rib, eye, and neurologic abnormalities. We report a rare case of Gorlin–Goltz syndrome in a 20-year-old male patient who presented with a slow growing swelling on lower right and left back teeth region since 2 months. Apart from these, other findings were frontal bossing, depressed nasal bridge, ocular hypertelorism, prominent supra orbital ridge, and mild mandibular prognathism. Excision was done and microscopic study revealed OKC and the follow-up could not be carried out for the complete management. We also presented a review of its pathogenesis, criterion, and differences between syndromic and nonsyndromic OKCs and suggest to thoroughly examine any patient who presents with multiple OKCs to rule out syndromic variety.

    Oral mucosal melanoma is a rare malignancy with the tendency to metastasize and locally invade tissues more readily than other malignant tumor of the oral cavity. It occurs approximately four times more frequently in the oral mucosa of the upper jaw usually on the palate or alveolar gingiva. The chameleonic presentation of malignant melanoma, its asymptomatic condition, rarity of the lesion, poor prognosis and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health care provider. Herein we report a rare and interesting case of oral malignant melanoma of the maxillary anterior gingiva, which was clinically and histopathologically diagnosed with a brief review of literature, has been discussed.

    To report laser pointer induced damage to retina and choroid and briefly review literature. A case report of a 13-year old Caucasian boy developed blurry central vision and central scotoma in right eye (OD). He was exposed for one minute to class IIIA green laser pointer of 650 nm wavelength and 5 mW power. Clinical examination showed a grayish lesion in foveal region. Ancillary testing revealed disruption of the retinal pigment epithelial (RPE) layer in foveal region and indocyanine green angiography demonstrated evidence of choroidal hypofluorescence suggestive of choroidal infarction in OD. Visual acuity improved from 20/100 to 20/60 in one day and he was treated with tapering doses of oral prednisolone (40 mg) for 3 weeks. Laser pointer with a power of >5 mW caused damage to RPE in the macula. Children should not be given laser pointers as toys especially those with label of danger instructions. PMID:22466425

    Encephalocraniocutaneous lipomatosis (ECCL) is a rare, sporadic congenital neurocutaneous disorder that characteristically involves ectomesodermal tissues, such as skin, eyes, and central nervous system. A 3-day-old girl presented with swelling in her right eye since birth. Ocular examination of the right eye showed hypertrophy of bulbar conjunctiva with limbal dermoid, clouding of cornea, and atypical upper eyelid coloboma. The left eye showed conjunctival congestion and corneal vascularization. Dermatological examination showed alopecia, nevus psiloliparus, focal dermal hypoplasia on forehead, multiple focal aplastic lesions on the scalp, skin tag at canthus, and lipoma in the fronto-temporal region. Imaging revealed calcification of the right globe, hydrocephalus, agenesis of corpus callosum, multiple intracranial cysts, calcification, and lipomas. The constellation of these clinical and the imaging findings led to a diagnosis of encephalocraniocutaneous lipomatosis. This case report and review of the literature is presented to provide a synopsis of problems likely to be encountered by an ophthalmologist who treats patients with ECCL. PMID:24881613

    Adipocere has a long history of frightening and fascinating mankind, from so called "incorruptible saints" to the famous "iceman" and its formation on human remains has long been known and feared. Adipocere formation replaces the putrefactive changes, when the body lies buried in shallow, moist, clay, soiled grave or it is thrown into cess pools or submerged in water. As the progression of putrefaction is arrested, the facial features and wounds are preserved without much alteration, thereby aiding the identification and to certain extent, the cause of death. The time required for the formation of adipocere is a subject of controversy. Here we present a case of early adipocere formation within 3 days and the review of literature pertaining to it.

    Fractures of the talus are uncommon, and talar body fractures in the sagittal plane are still rarer. The aim of its treatment is urgent anatomic reduction to restore congruency of the ankle and to reduce the risk of avascular necrosis by preserving any remaining blood supply. We report the case of a body talar fracture in sagittal plane associated with fracture of the medial malleolus in a young adult; the mechanism of the fracture was plantar hyperflexion, internal rotation and axial compression. We perform an open reduction and stabilization with two screws for the talus and screw the medial malleolus. At 14 months following the injury patient had good range of movement with little pain. The mechanism is discussed along with a literature review. PMID:25983480

    Spitz nevi account for approximately 1% of all melanocytic nevi of the skin in children. Although Spitz nevi often develop in the skin of the head and neck, intraoral Spitz nevi are rare. These nevi contain epithelioid and spindle cells and exhibit cytologic and architectural atypia when compared with routine melanocytic nevi, and may be mistaken for atypical Spitz tumor, Spitzoid melanoma, or conventional melanoma. Here, we report a Spitz nevus on the buccal mucosa of an 11-year-old boy. The tumor was composed of a proliferation of mostly epithelioid melanocytes with a smaller spindle cell component. The melanocytes were positive for S100, MART-1, and p16 proteins, with HMB-45-positive cells located only in the basal cell layer and superficial lamina propria. Less than 5% of the nuclei were positive for MIB-1, and there were no mitotic figures. We review the literature on 7 previously reported cases of Spitz nevi. PMID:24139994

    Diabetic mastopathy is a rare fibroinflammatory breast disease characterized by lymphocytic lobulitis, ductitis, and perivasculitis with stromal fibrosis. This lesion often presents as a discretely palpable uni- or bilateral mass in long-standing type I diabetes and other autoimmune diseases. We report a case of insulin-dependent diabetic mastopathy, which presented clinically as an indeterminate breast lump suspicious for malignancy. The patient is a 36-year-old woman who had type 1 insulin-dependent diabetes mellitus. Mammography and ultrasonography raised a suspicion of malignancy, and an excisional biopsy was performed. A previous biopsy had shown no evidence of malignancy. Histopathological examination now showed dense keloid-like stromal fibrosis with epithelioid-like and spindly myofibroblasts and a characteristic lymphocytic infiltration around blood vessels in and around lobules and ducts, features consistent with diabetic mastopathy. The literature is briefly reviewed. PMID:20740205

    Intracranial granulocytic sarcoma was a relatively rare tumor composed of myeloid blasts and/or immature myeloid cells in an extramedullary site which is associated with acute/chronic myeloid leukemia. In this paper, two cases of intracranial granulocytic sarcoma, one male aged 36 and one 28-year-old female, were reported to improve the diagnosis and treatment of such diseases. Diagnostic and treatment procedures for them were retrospectively summarized and relevant literature reviews were combined. Pathological biopsy was conducted to validate the diagnosis. Surgical resections in combination with chemotherapy were performed. The differential diagnosis of intracranial granulocytic sarcoma from malignant lymphomas and alternative small round cell malignancy was confirmed by biopsy and immunohistochemistry. PMID:26770615

    This descriptive case study illustrates the experiences of a 55-year-old male with a chronic disability resulting from a stroke, living in the community and a clinician's trial using occupation-based interventions predominately in a rehabilitation setting. The participant engaged in occupation-based interventions three times a week for 5 weeks guided by the Canadian Occupational Performance Measure (COPM). Data were collected through semi-structured interviews during the intervention sessions and journal entries made by the therapist. Results suggested occupation-based interventions facilitated a transformation for both the client and the therapist by enhancing the participant's occupational performance and the ability to resume previous roles. The therapist's belief in the power and value of occupation-based practice was reinforced and validated, particularly in the rehabilitation of an individual with chronic stroke. PMID:24867352

    Membrane adsorbents have emerged as powerful and attractive tools for the removal of hazardous materials such as dyes and heavy metal ions, mainly in trace amounts, from water resources. Among membrane adsorbents, those prepared from or modified with chitosan biopolymer and its derivatives are cases of interest because of chitosan advantages including biocompatibility, biodegradability, nontoxicity, reactivity, film and fiber forming capacity and favorable hydrophilicity. This review is oriented to provide a framework for better insight into fabrication methods and applications of chitosan-based adsorptive membranes. Critical aspects including thermokinetic analyses of adsorption and regeneration capacity of the membrane adsorbents have been also overviewed. Future of chitosan-based adsorptive membranes might include efforts for the improvement of mechanical stability and reusability and also most targeted application of appropriate copolymers as well as nanostructures in preparing high performance adsorptive membranes.

    Study Design Case report and literature review. Objective To present the first case of metastatic adamantinoma of the spine with immunohistochemical confirmation and an updated literature review. Summary of Background Data Spinal metastatic disease could be difficult to diagnose because of the multiple differential diagnoses involved. Spinal surgeons must be aware of unusual primary extra-axial tumors that metastasize to the spine because in certain cases the primary surgery must determine the prognosis of this lesion. Methods We present a fully documented case of a middle-aged man with tibial adamantinoma who developed spine metastasis, confirmed by immunohistochemistry. A literature review was done. Results Based on clinical, imaging, and pathology findings, we provide evidence for the first proven metastatic adamantinoma of the spine, adding this condition to the long list of differential diagnoses of secondary spinal disease. Conclusions Adamantinoma is a very rare bone tumor representing ∼1% of primary bone tumors. Spinal metastatic adamantinoma with immunohistochemical confirmation has not been described previously. Due to the lack of specific image findings or serum markers and multiple differential diagnoses, biopsy with immunohistochemical confirmation is mandatory, because “en block resection” might prove to be curative treatment.

    The aims of this review were to describe the case of a patient with debilitating neuroarthropathy of the ankles and feet and reveal a primary systemic (amyloid light chain, AL) amyloidosis and to review the relevant literature concerning the peripheral neuropathy and neuroarthropathy due to amyloidosis. We will emphasize the diagnostic pitfalls and discuss prognosis and treatments of both the peripheral neuropathy and the arthropathy related to AL amyloidosis. This is a descriptive case report of a patient with neuroarthropathy of the lower limbs due to AL amyloidosis. A review and discussion of relevant literature were conducted, based on a PubMed search from 1973 to December 2013. A 51-year-old female was diagnosed with AL amyloidosis after 20 months of investigation of small painful deformities of the feet. Chronic peripheral neuropathy occurs as a manifestation of AL amyloidosis in 25 % of cases. It may exceptionally be complicated by neuroarthropathy. In this case, the paucity of clinical and electrophysiological signs of the neuropathy delayed the diagnosis, leading to a severe arthropathy. The massive destruction of the joints dominated the clinical and the poor functional outcome. Diagnosis of AL amyloidosis should be considered in the presence of a mild peripheral neuropathy and a distal destructive and painless arthropathy. The two key diagnostic procedures are serum protein electrophoresis and nerve biopsy. Delay in treatment worsens the prognosis. PMID:25227773

    Purpose To report the case of a patient who developed late capsular block syndrome and to review the current literature regarding this complication of phacoemulsification procedures. Methods The literature was reviewed to summarize the diagnosis, classification, use of diagnostic aids, and the current treatments for this complication. Results A 69-year-old patient complained of decreased visual acuity 11 months after undergoing phacoemulsification. She was found to have a secondary myopization. Anterior segment ultrabiomicroscopy confirmed the diagnosis of capsular block syndrome. The patient underwent neodymium-doped yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy, which resulted in complete resolution of her symptoms. Conclusion Capsular block syndrome is a fairly rare complication of phacoemulsification procedures that, depending primarily on the timing of its occurrence following surgery, can develop into one of the three following possible clinical scenarios: intraoperatory, early postoperatory, and late postoperatory. In this patient, Nd:YAG laser capsulotomy was shown to be a safe and effective treatment option for this type of complication. PMID:25152612

    We present a case of afferent loop syndrome (ALS) occurring after pancreaticoduodenectomy (PD) in a patient who had previously undergone total gastrectomy (TG), and review the English-language literature concerning reconstruction procedures following PD in patients who had undergone TG. The patient was a 69-year-old man who had undergone TG reconstruction by a Roux-en-Y method at age 58 years. The patient underwent PD for pancreas head adenocarcinoma. A jejunal limb previously made at the prior TG was used for pancreaticojejunostomy and hepaticojejunostomy. Despite normal patency of the hepaticojejunostomy, he suffered from repeated postoperative cholangitis which was brought on by ALS due to shortness of the jejunal limb (15 cm in length). We therefore performed receliotomy in which the hepaticojejunostomy was disconnected and reconstructed using a new Y limb 40-cm in length constructed in a double Roux-en-Y fashion. The refractory cholangitis resolved immediately after the receliotomy and did not recur. Review of the literature revealed the lack of any current consensus for a standard procedure for reconstruction following PD in patients who had previously undergone TG. This issue warrants further attention, particularly given the expected future increase in the number of PDs in patients with a history of gastric cancer. PMID:24627609

    PURPOSE Spinal teratomas comprise a rare subset of spinal cord tumors, and here, we describe an even rarer childhood thoracic extradural–intracanalicular teratoma. The clinical presentation, management, and pathophysiology of these tumors are reviewed to promote recognition and guide treatment of these lesions. METHODS We report the case of a 21-month-old boy who presented with marked spasticity, as well as failure to ambulate and meet motor milestones. Additionally, we provide a literature review of spinal teratomas, including their clinical presentation, work-up, pathophysiology, and underlying genetics. Results An MRI of the spine revealed a large dorsal epidural tumor extending from T3 to T10 with heterogeneous contrast enhancement and severe spinal cord compression. The tumor was resected revealing a cystic mass with tissue resembling hair, muscle, as well as cartilage; pathology confirmed the diagnosis of teratoma. Gross total resection was achieved, and the child eventually gained ambulatory function. CONCLUSIONS Given that spinal teratomas are rare entities that can present with significant neurologic compromise, they must remain on clinicians’ differentials. Unfortunately, the exact origin of these tumors remains inconclusive and requires further investigation. PMID:24940089

    The aim of this article was to describe Descemet's membrane detachment (DMD) following phacoemulsification in five equine eyes and to review the human literature on this topic. In the last decade, there has been increased reporting of DMD in the human literature, in particular following cataract surgery. The natural history of DMD remains unknown and although various medical and surgical treatments have been advocated there is no recognized 'gold standard' treatment for DMD. This case series reports the diagnosis of DMD in four horses (5 eyes) in association with phacoemulsification surgery. The diagnosis of DMD in these patients was made intra-operatively, postoperatively or on subsequent histopathological examination. The surgical reports, photographic or video recordings, and ultrasound data were evaluated and possible factors associated with the pathophysiology of DMD are discussed. This is the first description of DMD in the veterinary literature, and the authors believe that DMD might hitherto have been overlooked in veterinary ophthalmology due to a lack of awareness of the condition. The possible causes, clinical signs, and treatment of DMD as described in the human literature are also reviewed. PMID:25180582

    Background Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. Patients and methods We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Conclusion Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients.

    Background Avascular necrosis of the hamate (hamate-AVN) is a seldom reported disease of which little is known on etiology, best treatment modalities, and outcome. Hamate-AVN can occur in multiple locations within the hamate. Case Description Case one was an 8-year-old girl with painful AVN of the hamate hook. Surgical excision of the hook was performed, leading to excellent results (follow-up 8 years). Case two was a 44-year-old man with hamate-AVN of the proximal pole surgically treated with a vascularized bone graft from the radius based on the fifth extensor compartment artery, leading to excellent results (follow-up 7 years). Case three was a 36-year-old woman with hamate-AVN of the proximal pole surgically treated with débridement and cancellous bone grafting, leading to poor results (follow-up 1 year). Literature Review Nine other cases of avascular necrosis of the hamate were found in literature, all but one treated surgically. Etiology, treatment, and results of these cases, combined with our own cases, are reviewed. Clinical Relevance This article summarizes and synthesizes all presented cases of avascular necrosis of the hamate. We hope this will be helpful to physicians in decision making when confronted with this rare entity. Level of Evidence 4. PMID:25364641

  16. Polyamide as a Denture Base Material: A Literature Review

    Vojdani, Mahroo; Giti, Rashin

    2015-01-01

    The purpose of this article was to review the biocompatibility, physical, and mechanical properties of the polyamide denture base materials. An electronic search of scientific papers from 1990-2014 was carried out using PubMed, Scopus and Wiley Inter Science engines using the search terms “nylon denture base” and “polyamide denture base”. Searching the key words yielded a total of 82 articles. By application of inclusion criteria, the obtained results were further reduced to 24 citations recruited in this review. Several studies have evaluated various properties of polyamide (nylon) denture base materials. According to the results of the studies, currently, thermo-injectable, high impact, flexible or semi-flexible polyamide is thought to be an alternative to the conventional acrylic resins due to its esthetic and functional characteristics and physicochemical qualities. It would be justifiable to use this material for denture fabrication in some cases such as severe soft/ hard tissue undercuts, unexplained repeated fracture of denture, in aesthetic-concerned patients, those who have allergy to other denture base materials, and in patients with microstomia.  Although polyamide has some attractive advantages, they require modifications to produce consistently better properties than the current polymethyl methacrylate (PMMA) materials. Moreover, since there is a very limited knowledge about their clinical performance, strict and careful follow-up evaluation of the patients rehabilitated with polyamide prosthesis is recommended.

    Introduction. Heterotopic pregnancy is a rare complication usually seen in populations at risk for ectopic pregnancy or those undergoing fertility treatments. It is a potentially dangerous condition occurring in only 1 in 30,000 spontaneous pregnancies. With the advent of Assisted Reproduction Techniques (ART) and ovulation induction, the overall incidence of heterotopic pregnancy has risen to approximately 1 in 3,900 pregnancies. Other risk factors include a history of pelvic inflammatory disease (PID), tubal damage, pelvic surgery, uterine Mullerian abnormalities, and prior tubal surgery. Heterotopic pregnancy is a potentially fatal condition, rarely occurring in natural conception cycles. Most commonly, heterotopic pregnancy is diagnosed at the time of rupture when surgical management is required. Case. This paper represents two cases of heterotopic pregnancies as well as a literature review. Conclusion. Heterotopic pregnancy should be suspected in patients with an adnexal mass, even in the absence of risk factors. Clinicians must be alert to the fact that confirming an intrauterine pregnancy clinically or by ultrasound does not exclude the coexistence of an ectopic pregnancy. A high index of suspicion in women is needed for early and timely diagnosis, and management with laparotomy or laparoscopy can result in a favorable and successful obstetrical outcome. PMID:27413561

    2013-01-01

    ABSTRACT Gorlin and Goltz syndrome are a very complex syndrome and a multisystemic process that is characterized by the presence of multiple pigmented basocellular carcinomas, keratocysts in the jaws, palmar and/or plantar pits and calcification of the falx cerebri. Along with these major features a great number minor features have also been described which involves numerous skeletical, dermatology related, neurological, ophthalmological and reproductive anomalies. It exhibits high penetrance and variable expressivity. Presented here is the case of Gorlin-Goltz in a 12 years old male patient which was diagnosed through its oral and maxillofacial manifestations. Treatment of odontogenic keratocyst was done by enucleation without primary suturing. Iodoform dressing was kept to enhance the healing and to reduce the recurrence of the lesion. It is important to provide the early diagnosis for detection of clinical and radiological manifestations in young patients and for provision of advice concerning preventive treatment like protection of the skin from the sunlight and genetic sensitivity testing so that possible complications associated with this syndrome can be prevented.

    We describe a case of 42-year-old female presenting with abdominal pain associated with loss of weight and fever for 8 mo. On evaluation she had gross hepatomegaly with raised alkaline phosphatase and raised GGT levels with normal transaminases and bilirubin. On imaging she had diffuse enlargement of liver with heterogeneous contrast uptake in liver. Her viral marker and autoimmune markers were negative. Liver biopsy depicted massive deposition of amyloid in peri-sinusoidal spaces which revealed apple green birefringence on polarizing microscopy after Congo red staining. Cardiac and renal evaluation was unremarkable. Abdominal fat pad and rectum biopsy was negative for amyloid deposit. There was no evidence of primary amyloidosis as bone marrow examination was normal. Serum and urine immunofixation electrophoresis were normal. Immunoperoxidase staining for serum amyloid associated protein for secondary amyloidosis was negative from liver biopsy. We present this rare case of primary hepatic amyloidosis and review the literature regarding varied presentations of hepatic involvement in amyloidosis. PMID:26962400

    Arteriovenous shunts of the neck and facial region rarely involve the external carotid artery and its branches. Most cases are considered to be iatrogenic or related to trauma but congenital shunts are rare. Parachordal arteriovenous fistulae are a group of embryologically derived arteriovenous shunts caused by defects involving the notochord, giving rise to cranial and paraspinal shunts. In the cranial regions, these shunts involve exclusively the metameric arteries--maxillary, ascending pharyngeal, occipital and vertebral. Signs and symptoms are variable, depending on the feeding vessel but also on the characteristics of the draining pathway. We report the case of a 17-year-old male patient with a shunt between the right internal maxillary artery and right external jugular vein detected at the age of 6, not associated with trauma, which we decided to treat because of an enlargement of the right cardiac atrium detected on routine examination. Digital subtraction angiography was performed to characterize the shunt followed by partial embolization with ballooning, coiling and Onyx injection. Echographic control 6 months after the procedure was compatible with complete occlusion of the shunt. We also perform a short review on this extremely rare entity. PMID:26825132

    First clinical report of Harlequin color change (HCC) phenomenon came in 1952 from Neligan and Strang. Since then, HCC has been described in a fairly broad number of clinical reports involving neonates, infants, children, and adult patients. We here present a small case series of HCC occurring in neonates, pointing out three of the different possible presentations (hemifacial, patchy scattered across the whole body, and hemiscrotal) of this phenomenon. A brief discussion and literature review encompassing epidemiology, clinical features, physiopathology, associated conditions, and differential diagnoses of HCC is then presented. In most cases, HCC represents a benign, idiopathic, and rapidly autoresolutive phenomenon, with no need for treatment. Some drugs (especially anesthetics and prostaglandin E) are thought to enhance HCC expression through their influence on the capillary tone in the peripheral vascular bed; this effect is anyway promptly reversible with drug withdrawal. Only in rare circumstances, HCC may act as a clue for serious central nervous system disorders (e.g., meningitis; hypothalamic, brain stem, or sympathetic nervous system lesions); anyway, in these rare occurrences HCC always represents an epiphenomenon of the disease, never acting as the sole sign of the underlying disorder.

    An ocular jellyfish sting is an ophthalmic emergency and is rarely reported in the medical literature. With the evolution of aquatic activities and entertainment in recent decades, we anticipate that more patients with ocular jellyfish stings may be taken to the emergency department. However, most physicians are unaware of the typical presentations, suitable treatments, prognosis, and possible complications of ocular jellyfish stings. We reported 2 cases with ocular jellyfish stings and collected cases series from literature review. The most common clinical features of ocular jellyfish stings were pain, conjunctival injection, corneal lesion, and photophobia. All patients who sustained ocular stings did so during aquatic activities, and the best management at the scene was proper analgesics and copious irrigation of affected eyes with seawater or saline. The ocular lesions were treated with topical cycloplegics, topical steroids, topical antibiotics, topical antihistamines, and removal of nematocysts. The prognosis was good, and all patients recovered without any permanent sequelae. However, symptoms in some patients may last longer than 1 week. Reported complications included iritis, increased intraocular pressures, mydriasis, decreased accommodation, and peripheral anterior synechiae. PMID:27436284

    2016-01-01

    Background: Acute patellar dislocation is a common injury in young people, especially in adolescent females and athletes. Lateral dislocation is the most common form of patellar dislocation and often reduces spontaneously or with simple manipulation and closed reduction. We report a rare circumstance in which the patella was irreducible and required manipulation and closed reduction in the operating room. Case Report: While dancing, a 32-year-old female was knocked by a fellow dancer on her left knee, and she fell to the nightclub floor. She was unable to stand or bear weight because of the pain, and her knee was in fixed flexion with lateral displacement of the patella. Multiple attempts at closed reduction under sedation failed in the emergency department. Computed tomography (CT) images revealed a medial border patellar fracture and lipohemarthrosis that required closed reduction and manipulation in the operating room. The patient was placed in a Richards splint for follow-up and referred to a physiotherapist for conservative management. Conclusion: This case highlights the fact that some lateral patellar dislocations are irreducible on initial attempts, particularly if a fracture is present or another mechanism of impingement impedes relocation. CT imaging is a valuable diagnostic tool, and manipulation under anesthesia or open reduction in the operating room may be necessary. Our review of the literature further highlights the complexity and potential problems associated with treatment of locked lateral patellar dislocations. PMID:27303231

    Hermansky-Pudlak syndrome (HPS) is a rare genetic disorder, the most common complication of which influencing the prognosis is pulmonary fibrosis. In the present report, we describe an autopsy case of a Japanese woman with HPS. The patient was diagnosed at 50 years of age based on the presence of oculocutaneous albinism, hemorrhagic diathesis, ceroid-lipofuscin accumulation and pulmonary fibrosis. Although systemic steroids, immunosuppressants and pirfenidone were administered for pulmonary involvement, she died from respiratory failure two years later. Obtaining an early diagnosis and taking into consideration the need for lung transplantation is necessary in order to improve the prognosis of HPS. We herein report this very rare Japanese case of HPS with a review of the treatment approaches for HPS complicated with pulmonary fibrosis. PMID:25447654

    Gaucher's disease (GD) is a lysosomal storage disorder due to glucocerebrosidase deficiency; it's one of the rare genetic diseases for which therapy is now available. The purpose of this work is to study the epidemiological features of the disease and to highlight the diagnostic difficulties. We performed an 11-year retrospective study of 11 patients with GD followed-up in the department of paediatric hepatology gastroenterology and nutrition of Rabat children's Hospital. We observed 11 patients with GD: 6 males and 5 females. Age at onset ranged from 3 months to 10 years with an average of 3.41 years. Mean age at diagnosis was 4 years (range 3months-14years). Parental consanguinity was noted in 85% cases. According to the clinical presentation, we classified our patients into: 9 cases of type 1 (81%) and two cases of type 2 (19%), none of the patients presented GD type 3. GD type 1: The age at diagnosis ranged from 2 years to 14 year with an average of 6 years. Main symptoms were: splenomegaly, hepatomegaly, pallor, haemorrhagic appearance (40%), bone pain (40%). The diagnosis was based on histology showing the Gaucher's cells in various tissues (100%). Enzymatic activity dosage confirmed the diagnosis of GD for 4 patients (44.5%). The treatment was always symptomatic (analgesics, transfusion). A splenectomy was performed in one case presenting with multiple splenic abscesses and high transfusion requirements. None of the patients received a specific treatment (substitutive enzymotherapy). The follow-up period ranged from 3 months to 6 years with an average follow-up of 4 years. We noticed stability in 4 cases, 2 worsening cases with bone and spleen complications. Three patients were lost to follow-up. GD type 2: we observed two cases of GD type 2 diagnosed at 3 and 18 months. The visceral symptoms were serious and the neurological features included seizures, hypertony, squint, physical developmental milestones delay. Both of them died. Gaucher's disease is not

    Tracheobronchopathia osteochondroplastica (TO) is a relatively rare and benign disease of unknown etiology that is characterized by the accumulation of diffuse cartilaginous and osseous nodules protruding into the anterolateral walls of the trachea and bronchus. However, TO is easy to ignore or misdiagnose due to its nonspecific clinical manifestation. A chest computed tomography (CT) scan with a fiber bronchoscope and pathological biopsy shows the clinical features supporting the ultimate diagnosis.Here, we report 2 misdiagnosed cases of TO and review the literature to further define the diagnosis for clinicians. The first case was a 34-year-old male admitted to the hospital because of recurrent cough and intermittent fever for 10 years. CT scans showed irregular stenosis of the main bronchus and bronchofibroscope showed multiple nodules producing into the lumen. He was initially misdiagnosed of bronchial tuberculosis and received antitubercular agents for nearly half year. Symptoms got no relief and another bronchofibroscope with biopsy tests in our hospital exactly diagnosed of TO. Symptoms were significantly relieved after receiving budesonide associated with antibiotics, etc. Another case was a 46-year-old woman presenting with a history of repeated hoarseness for 8 years and a 2-month exacerbation. She underwent an electronic laryngoscopy 3 times and was diagnosed of laryngitis. Symptoms got no relief after antiinflammatory. CT scan indicated variable degrees of stenosis and calcification of the distal trachea and main bronchi and bronchofibroscope showed dozens of white nodules extruding into the lumen. Histopathologic findings revealed the ultimate diagnosis of TO and antiinflammatories, spasm relievers, and inhaled corticosteroids, showed apparent effects.Poor specificity of TO is observed in clinical manifestation and laboratory inspection. However, a CT scan associated with a bronchoscopy and histopathologic examination greatly contributes to a

    Pregnancy, the implantation of a fertilized ovum outside the endometrial cavity, occurs in 1.5%-2% of pregnancies. It is one of the major causes (about 6%) of maternal death during the first trimester of pregnancy. The remaining 5% implant in the ovary, peritoneal cavity, within the cervix, and the omental pregnancy is the least common form of abdominal pregnancies. A review of the literature on Medline for the period 1958-2012 reported only 16 cases of omental pregnancy. Here we report a case of primary omental pregnancy in a nulliparous woman. A 24 year-old woman gravid 1, para 0, with lower abdominal pain. Her last menstrual period occurred 8 weeks before the visit. The physical examination revealed abdominal tenderness in the lower quadrants, she was not bleeding. Transvaginal ultrasound showed: a free anechoic/hypoechoic area of 30 x 57 mm in the pouch of Douglas and the endometrium was homogeneus with a thickness of 12 mm and no evidence of gestational sac in the uterine cavity. Laboratory data revealed a normal cell blood count and beta hcg levels of 8047 IU / L. Because of continuing abdominal pain and a diagnosis of ectopic pregnancy a diagnostic laparoscopy was performed, which showed hemoperitoneum. Further inspection of abdominal cavity revealed a bloody lesion that was tenaciously adherent to the omentum, using non traumatic laparoscopic forceps and bipolar scissors we carefully removed a friable mass of about 30 mm from the omental attachments. Histological examination showed the presence of blood clot material mixed with trophoblastic tissue. Ultrasound evaluation and and hCG assessment are important to determine the extrauterine location of the ectopic pregnancy but the early diagnosis of abdominal pregnancy requires also a laparoscopic evaluation and, as our case has highlighted, thorough abdominal exploration especially in the absence of adnexal findings when ectopic pregnancy is highly suspected. Early diagnosis of omental pregnancy is difficult

    Littoral cell angioma (LCA) is a rare splenic vascular neoplasm that arises from the cells lining the red pulp sinuses. It is deemed to be a benign and incidental lesion. The earliest literature report of littoral cell angioma has been described by Falk. The examination of samples after splenectomy reveals similar pathological change and its change rule is summarized. However, many recent reports have described it to be a malignant tumor with congenital and immunological associations. Generally speaking, the definitive diagnosis can only be made after histological and immunohistochemical profiles. In this case report, we presented the case of a 48-year-old woman with multiple splenic LCAs. Initially, the patient was characteristics of abdominal distension, weakness and fatigue. Multiple hemangiomas were observed in the spleen through abdominal ultrasonic diagnosis. Computed tomography (CT) scans revealed the splenomegaly with multiple round and hyperdense lesions. The patient subsequently underwent splenectomy. Postoperative histological and immunohistochemical studies confirmed the diagnosis of LCA. Based on the presentation of this case, clinical, radiographic and pathological results of LCA as well as recent advances in our understanding of this uncommon splenic lesion were reviewed. LCA is an uncommon splenic tumor diagnosed in patients with or without abdominal discomfort. Only a few case reports regarding this kind of tumor have been published as inconsistent results. In the present paper, we have reported a case of LCA and reviewed the literature. PMID:22172167

    Our aim was to describe a patient who experienced a postpneumococcal Moyamoya syndrome (MMS), with a great involvement of the posterior cerebral circulation, and to review the MMS postinfective cases. A 55-year-old Pakistani man with a history of pneumococcal meningitis 3 months before developed acute headache, left otalgia and body paresthesiae. Brain CT showed a right occipital ischaemic lesion. Seven days later, he developed acute left haemianopsia, haemiplegia, haemineglect and 'frontal' cognitive and behavioural symptoms. A second brain CT and MRI disclosed an increase in the occipital lesion and the appearance of a further one in the right frontal lobe. Cerebral CT and MRI-angiography were consistent with Moyamoya vessel alterations. Treatment with antiplatelets, methylprednisolone, followed by prednisone tapering, and motor rehabilitation began. Six months later, no relapses had occurred. Our case represents a delayed manifestation of postmeningitis vasculopathy. Meningitis may represent a risk factor for developing a disabling cerebrovascular disease like MMS. PMID:23391943

    The primary intracranial development of olfactory neuroblastomas, outside olfactory epithelium, is rare. We report a case of primary sellar neuroblastoma without any aggressive histopathological features, managed solely surgically without adjuvant therapy, with good outcomes at 3 years. Primary sellar neuroblastomas mostly occur in women in the 4th decade with a context of a non-secreting pituitary tumour. Diagnosis is made on histopathological examination (small cells, fibrillary intercellular background, strong immunoreactivity for neurons markers, negative immunoreactivity for anterior pituitary hormones). Management is based on surgery. Adjuvant treatment is not consensual, largely depends on patient's conditions and aggressive histopathological features. PMID:22497798

    Malignant peripheral nerve sheath tumours are extremely rare and can be associated with neurofibramatosis type 1. Their prognosis is poor and surgery remains the mainstay of therapy and should be the first line of treatment. Radiotherapy and chemotherapy are second line treatment and their effectiveness remains to demonstrate. The diagnosis is clinical, radiological, histological and immunohistochemical. Malignant peripheral nerve sheath tumours have a potential of local tumour recurrence very high and can metastasize. They often occur in extremity of the members but also rarely into brain. We report two cases of intracerebral nerve sheath tumour. The first was a 68-year-old woman who was admitted with progressive symptoms of headache and diplopia. A left frontotemporal malignant peripheral nerve sheath tumours was diagnosed and was treated by surgery and irradiation. Ten months later, she presented a local recurrence and spine bone's metastases were treated by vertebroplasty and irradiation. The patient died 15 months after the diagnosis. The second case was a 47-year-old woman who was referred because headache and vomiting symptoms. A right frontal malignant peripheral nerve sheath tumours was diagnosed and treated by surgery and irradiation. After that, the patient had three local recurrence operated and pulmonary and cranial bone's metastases. She was still alive after 20 months. We propose a literature review with 25 cases of intracerebral nerve sheath tumour identified, including the two current cases. PMID:26934901

    FOLFIRINOX is a standard chemotherapeutic regimen for patients with advanced pancreatic cancer who have a good performance status. In this study, we present the case of a 64-year-old male who developed dysarthria following FOLFIRINOX treatment, and review all four cases of dysarthria encountered among the nine patients who received this treatment in our hospital. In all cases, dysarthria occurred during the infusion of irinotecan in the first course of treatment, persisted for several hours, and then resolved rapidly without any sequelae. Physical and neurological examinations at the onset of dysarthria revealed no other abnormalities. Imaging studies revealed no abnormal findings. Atropine was prophylactically administered in the second and subsequent courses of treatment and effectively prevented or alleviated dysarthria. This acute neurological symptom is surprising and uncommon in traditional cancer chemotherapy, and medical oncologists may initially suspect the onset of stroke or cerebrovascular disease. However, consistent with our experience, all reported cases resolved completely, with no need for dose reduction or treatment interruption. PMID:26622908

    Throat cuts could be of homicidal, suicidal or accidental origin. In the cases of death from cut throat, suicide can be distinguished from homicide based on the type and location of the wound and crime scene investigation. The purpose of the current study is to attract attention to the instructive findings for origin determination in deaths by cut throat according to the number and characteristics of the wounds and crime scene investigation. We have reviewed the files of autopsies performed between the years of 2000 and 2010, and compared with previously published case reports; all results were summarized in the current study. The results showed that 60% of cases were male, 40% were female, with 27.9 years of average age. The mean number of wounds was calculated to be 34.3 per case for honor homicides, 7.4 per case for other homicides, and 2.0 per case for suicides. Numbers of wounds were approximately 5 times higher in the honor homicides compared to other homicides. If the number of wounds were excessive, possibility of honor killings should be taken into account. When the killer was a parent not in psychosis, hesitation cuts were detected. Additional lesions were present in 46.7% of the cases, and they were assessed as homicide. Presence of vertebral notch and spinal cord cuts, which require a substantial amount of force and pressure via sharp tools, indicates homicide. PMID:23622458

  2. A literature review of email-based telemedicine.

    2010-01-01

    A structured analysis of peer-reviewed literature about the delivery of health services by email was undertaken for this review. A total of 185 articles were included in the analysis. These articles were thematically categorised for medical specialty, participants, sub-topic, study design and service-delivery application. It was shown that email-based telemedicine can be practiced in a large number of medical specialties and has application in primary consultation, second opinion consultation, telediagnosis and administrative roles (e.g. e-referral). Email has niche applications in low-bandwidth, image-based specialties (e.g. dermatology, pathology, wound care and ophthalmology) where attached digital camera images were used for telediagnosis. Diagnostic accuracy of these images was the predominant topic of research and results show email as a valid means of delivering these medical services. Email is also often used in general practice as an adjunct for face-to-face consultation. Further, a number of organisations have significantly improved the efficiency of their outpatient services when using email as a triage or e-referral system. Email-based telemedicine provides specialist medical opinion in the majority of reviewed services and is most likely to be instigated by the patient's primary care giver. However, email-consultations between patient and primary care and patient and secondary care are not uncommon. Most email services are implemented using ordinary email. However, a number of organisations have developed purpose-written email applications to support their telemedicine service due to impediments of using ordinary email. These impediments include lack of management tools for: the allocation and auditing of cases for a timely response and the co-ordination of effort in a multi-clinician, multi-disciplinary service. The ability to encrypt ordinary email thereby securing patient confidentiality is also regarded as difficult when using ordinary email. Hence

    Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

    Primary hepatoid carcinoma of the ovary (HCO) is a rare aggressive tumor that typically presents at an advanced stage in postmenopausal women with unilateral or bilateral ovarian masses and elevated AFP and CA125. We report a case of HCO in a 73 year-old woman who presented with abdominal distention, weight loss, and a large lower abdominal mass. Postoperative serum AFP was markedly elevated and trended down with initiation of chemotherapy. Review of the literature revealed thirty-two reported cases with no consensus on histogenesis or consistent immunohistochemical profile other than positive AFP staining in all but one case. Although the optimal treatment has not yet been determined, tumor debulking surgery followed by a platinum and taxane based chemotherapy regimen has shown promise. Both serum AFP and CA125 appear to have prognostic value and can be used to follow response to treatment and screen for recurrence. PMID:26425726

    Lamotrigine is an anticonvulsant medication that also has utility in the treatment of bipolar disorder. It has been associated with many side effects, including rashes that can progress to Stevens-Johnson syndrome or toxic epidermal necrolysis. It has also been associated with the development of motor tics, most commonly in the head, neck, and shoulders. We will now present the case of a 45-year-old woman who developed tics that involved the entire left side of her body after her dose of lamotrigine was increased from 200 mg daily (2.0 mg/kg/day) to 225 mg daily (2.3 mg/kg/day). We will review the prior cases of lamotrigine induced tics, and compare them to the circumstances surrounding our patient. We will also discuss the neurobiology of tics and make suggestions to improve the tics, based on the reported cases. PMID:26537524

    Pituitary carcinomas are rare malignant neoplasms with diagnostic and management challenges. Patients with pituitary carcinomas have extremely poor outcomes. In this report, the authors describe two cases of pituitary carcinomas with intraspinal metastasis (Case 1: 42-year-old man with a history of pituitary adenoma 16 years ago developed an intraspinal lesion at C4-C5; Case 2: 26-year-old women with a history of growth hormone-producing pituitary adenoma 9 years ago developed intraspinal lesion in the sacral canal). Both patients underwent spine surgery. The intraspinal lesions were confirmed as metastatic pituitary carcinomas based on the histomorphology and immunohistochemical stains. The authors reviewed the literature for the diagnosis, treatment, and prognosis of intraspinal metastasis from pituitary carcinomas. PMID:26464743

    Primary syphilic chancre most often involved genitalia, with 12% to 14% extragenital lesions. This article describes a rare case of a female patient with labial ulcer and diagnosed as oral syphilis (OS), an uncommon presentation of primary syphilis. OS is transmitted through orogenital contact.This study is case report and literature review.We report a 27-year-old woman with painless, ulcerative, and indurated lesion on her lower lip and a 7-day history of symmetrically distributed nonpruritic macules. OS was diagnosed based on clinical presentations and serologic test and patient's oral ulcer was cured with intramuscular penicillin G benzathine. However, both the patient and her husband denied any orogenital sexual history before. In addition, her husband was also diagnosed as syphilis later in our clinic. He reported having orogenital contact with other people.Therefore, this is a rare case of OS transmitted through kissing. PMID:27057901

    Priapism is a urological emergency defined as persistent penile erection that is unrelated to sexual stimulation and typically involving only the corporal cavernosa. It can occur as a rare side effect of antipsychotic medications and is mediated via their α-adrenergic antagonist effect. In this paper we describe a case of priapism in a patient started on risperidone and sodium valproate. We also review the South London and Maudsley Case Register Interactive Search database to assess how many other cases of priapism were reported in patients taking risperidone. We add this information to a literature review of cases of priapism associated with risperidone. PMID:23983987

    The incidence of anthrax is decreasing in Turkey, however, it is still endemic in some regions of the country. Although central nervous system involvement is rare in cases with anthrax, high mortality rates are significant. Here, we report a 46-years old woman who was anthrax meningoencephalitis. The patient was from Yozgat located in Central Anatolia, Turkey. Her history revealed that following peeling the skin of sheeps and consuming their meat a week ago, a lesion developed in her left forearm and she had been treated with penicilin G with the diagnosis of cutaneous anthrax in a local health center. The patient was admitted to the emergency room of our hospital due to increased headache and loss of conciousness and diagnosed as anthrax meningitis. Crytallized penicilin G (24 MU/day IV) and vancomycin (2 g/day IV) were initiated. The macroscopy of cerebrospinal fluid (CSF) sample was haemorrhagic, white blood cell count was 40/mm3 (80% of neutrophil) and Gram staining of CSF yielded abundant gram-positive bacilli. The diagnosis was confirmed by the isolation of Bacillus anthracis from CSF culture. Although the isolate was susceptible to penicillin and dexamethasone was added to the treatment, the patient died. Review of the Turkish literature revealed seven cases of anthrax with central nervous system involvement between 1980-2008. One of the patients was an 11-years old boy and the others were adults aged between 19 and 64 years. The source of the infection was skin in four patients and inhalation in one patient. The most common findings in all of the patients were inhabitance in rural area, haemorrhagic CSF and loss of all patients despite appropriate antibiotic therapy. In conclusion, anthrax meningitis and meningoencephalitis should be considered in the differential diagnosis of haemorrhagic meningitis in areas where anthrax is endemic and high rate of mortality despite appropriate therapy should always be kept in mind.

However, e-research methodologies, such as the e-Delphi technique, have yet to undergo critical review. This study advances methodological discourse on the e-Delphi technique by critically assessing an e-Delphi case study. The analysis suggests that the benefits of using e-Delphi are noteworthy but the authors acknowledge that researchers are likely to face challenges that could potentially compromise research validity and reliability. To ensure that these issues are sufficiently considered when planning and designing an e-Delphi, important facets of the technique are discussed and recommendations are offered to help the environmental researcher avoid potential pitfalls associated with coordinating e-Delphi research.

    This report describing the radiology of transsphenoidal hypophysectomy based on a review of 100 consecutive surgical procedures. Preoperative laminographic evaluation of the sphenoid sinus is an important aid in planning the most direct surgical approach to the pituitary. It is also useful in defining the many anatomic structures that may be injured inadvertently at the time of surgery. Intraoperative radiography or fluoroscopy is helpful in identifying the sella floor and as an aid in preventing loss of orientation within a capacious sinus. Various changes occur within the sphenoid sinus following surgery, some transient and others persistent. The surgical defect is usually difficult to identify on routine roentgenograms but is clearly visible on lateral laminography. A persistent soft tissue mass within the sinus is usually a manifestation of fascia and fat placed as a seal within the sinus. PMID:970530

    PURPOSE Results of case management designed for patients with dementia and their caregivers in community-based primary health care (CBPHC) were inconsistent. Our objective was to identify the relationships between key outcomes of case management and barriers to implementation. METHODS We conducted a systematic mixed studies review (including quantitative and qualitative studies). Literature search was performed in MEDLINE, PsycINFO, Embase, and Cochrane Library (1995 up to August 2012). Case management intervention studies were used to assess clinical outcomes for patients, service use, caregiver outcomes, satisfaction, and cost-effectiveness. Qualitative studies were used to examine barriers to case management implementation. Patterns in the relationships between barriers to implementation and outcomes were identified using the configurational comparative method. The quality of studies was assessed using the Mixed Methods Appraisal Tool. RESULTS Forty-three studies were selected (31 quantitative and 12 qualitative). Case management had a limited positive effect on behavioral symptoms of dementia and length of hospital stay for patients and on burden and depression for informal caregivers. Interventions that addressed a greater number of barriers to implementation resulted in increased number of positive outcomes. Results suggested that high-intensity case management was necessary and sufficient to produce positive clinical outcomes for patients and to optimize service use. Effective communication within the CBPHC team was necessary and sufficient for positive outcomes for caregivers. CONCLUSIONS Clinicians and managers who implement case management in CBPHC should take into account high-intensity case management (small caseload, regular proactive patient follow-up, regular contact between case managers and family physicians) and effective communication between case managers and other CBPHC professionals and services.

    Congenital temporomandibular joint (TMJ) ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse. This echoes our own experience where there was recurrence of the ankylosis. However, after removal of the ankylotic mass, the patient maintains a satisfactory maximal incisal opening (MIO) till the present day. The additional challenges faced in the congenital form in addition to the already complex management of acquired paediatric temporomandibular joint ankylosis are (1) much earlier insult to the TMJ, (2) reduced opportunity for neuromuscular development of the muscles of mastication, and (3) reduced compliance with postoperative physiotherapy programmes due to the younger age of these patients.

    Pasteurella multocida is a common commensal of the gastrointestinal and respiratory tracts of animals, especially cats and dogs. It is transmitted to humans through contact with animals. Bite wound infection is the most common clinical manifestation. Systemic infections are unusual and mainly affect immunocompromised individuals. The article presents two cases of Pasteurella infection. Wound infection in a 75-year-old female following a bite from her pet cat was associated with bacteremia. The disease course was favorable with the initial clindamycin treatment despite in vitro resistance. The other patient was a 62-year-old female diagnosed with acute bacterial meningitis with multiple brain abscesses and transient expressive aphasia. She reported frequent contacts with pets and domestic animals without a recent bite. Hematogenous dissemination of the infection was suspected. Because of poor therapeutic response, cefotaxime was switched to chloramphenicol which was later switched to a combination of cefotaxime with ciprofloxacin due to anemia. Following 6 weeks of intravenous antibiotic therapy and another 10 weeks of oral ciprofloxacin therapy, magnetic resonance imaging showed normal results and the neurological defect resolved. Epidemiological, clinical and therapeutic aspects of Pasteurella infection are discussed and literature is reviewed. PMID:26312375

    Multiple subpial transection (MST) is a novel technique in surgery for epilepsy, employed in patients where some or all of the epileptogenic zone cannot be resected because it lies in a vital cortical area. Twenty one patients subjected to MST were reviewed. Eighteen patients had medically intractable epilepsy and three patients had Landau-Kleffner syndrome. Their ages ranged from 6 to 47 (mean 15-9) and duration of epilepsy ranged from 0.33 to 42 (mean 8.6) years. Preoperative MRI showed focal abnormalities in eight cases. Detailed electrophysiological examination was carried out on all patients. Brain resection was performed in addition to MST in 12 patients. A further six patients underwent brain biopsy. Three patients with Landau-Kleffner syndrome were subjected neither to resection nor to biopsy. Histopathological examination showed Rasmussen's syndrome in six patients, cortical dysplasia in six, cerebral tumour in one, and non-specific changes in five. Multiple subpial transection was carried out mainly in precentral and postcentral regions. Eighteen patients have been followed up for one to five years, and three for 10 months. The three patients with Landau-Kleffner syndrome were mute before operation and have shown substantial recovery of speech. Of the other 18, 11 showed a worthwhile decrease in seizure frequency. None of the patients developed chronic neurological deficits attributable to MST. It is concluded that MST leads to worthwhile seizure control without major neurological deficit in patients who would otherwise be inoperable. PMID:7897419

    We present a case of a postpartum female with iliopsoas fasciitis in the puerperium. Two days after a spontaneous vaginal delivery at 38 weeks without any complications, the patient complained of pain in the left thigh and hip, associated with a temperature of 38 degrees C. Consequently, she could not walk 4 days after delivery and her body temperature had increased to 39 degrees C. Extreme left flank pain and tenderness in the left pelvic wall were prominent, whereas the tenderness in the pelvis was moderate. Magnetic resonance imaging led us to diagnose iliopsoas fasciitis. This was complicated by sepsis but improved after a protracted antibiotic treatment without any surgical intervention. A literature review revealed that serious complications, including sepsis or permanent functional disturbance, could arise although retroperitoneal fasciitis and/or abscesses are very rare after vaginal delivery. Iliopsoas fasciitis could be considered when patients complain of extreme pain in the pelvic wall, sacroiliac joint region, or thigh-symptoms that are uncommon in uncomplicated endometritis.

    Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. Management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. Metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reaction and lead to serious complications. Despite the modern imaging methods, it is often difficult to identify and locate organic intraorbital foreign bodies. This paper presents a review of nine cases of impacted foreign bodies in the orbital region and discusses the diagnosis and treatment of this kind of injury. The following data were collected: age, gender, etiology of injury, occurrence of fracture, anatomical location of fracture, type of object, signs and symptoms, type of imaging exam used, approach, transoperative complication and occurrence of death. Foreign body injuries in the orbital region can be treated with a combination of clinical suspicion, basic knowledge and diagnostic tests and depend on the skill and experience of the surgeon, thereby decreasing the surgical risk of iatrogenic injury in relation to the inherent risk of retaining an organic intraorbital foreign body.

    Pituitary carcinomas are extremely rare. In general, the initial clinical, biochemical, and histological characteristics are of minimal utility in distinguishing benign adenomas from pituitary carcinomas. We describe a 63-year-old woman with a macroprolactinoma, who presented with diplopia and blurred vision. This unusual initial presentation and the subsequent aggressive clinical course, with diffuse local and distant intramedullary metastases, prompted us in retrospect to make a detailed analysis of the therapeutic interventions and histology. In addition, we reviewed all available literature on published cases of malignant prolactinoma and detailed their epidemiological, clinical, and histopathological characteristics. In brief, it is postulated that pituitary carcinomas arise from the transformation of initially large, but benign, adenomas. Unusual and/or atypical clinical manifestations appear to occur more frequently. In vivo, the development of dopamine agonist resistance in invasive macroprolactinoma is indicative of malignancy and should prompt the clinician to perform a biopsy of the tumor. For pituitary tumors that exhibit high mitotic activity, increased Ki-67 and/or p53 immunoreactivity, it may be useful to denote these tumors as 'atypical' prolactinomas to raise the possibility of future malignant development.

    Dissociative amnesia that encompasses one's entire life and identity is a rare disorder, as is dissociative fugue. In evaluating such cases, a dichotomy is often invoked between functional and organic etiologies. However, this dichotomy suffers from both conceptual and ethical flaws. Conceptually, putative brain-based, organic etiologies for many dissociative disorders-including dissociative amnesia-exist. Ethically, such dichotomies may result in dismissive care for patients with distress-based disorders like dissociative amnesia. In support of humane, neurobiologically informed treatment of patients with dissociative amnesia, we present excerpts from 2 post-event interviews with a patient who suffered and recovered from an episode of dissociative amnesia and fugue. Following this, we review current neurobiological models of dissociative amnesia that undermine the dichotomy of functional versus organic, and suggest that the crucial distinction in such cases is between a patient's willful, conscious deceit and processes that occur without conscious intent.

    Although cases of Selective Serotonin Reuptake Inhibitor (SSRI) induced akathisia have often been reported in literature, this adverse effect has not adequately been mentioned in major pharmacology textbooks. As a result, SSRIinduced akathisia is very frequently under-recognized. A review of literature showed that almost all frequently used SSRIs such as Fluvoxamine, Fluoxetine, Sertraline, Citalopram have been reported to be causing akathisia. SSRI-induced restless legs syndrome and movement disorders have also been reported. However, Escitalopram-induced akathisia is rare. In our review of literature, we could find only one single case of Escitalopram-induced severe akathisia. And this specific SSRI drug has rarely been implicated with occurrence of restless legs syndrome and extra-pyramidal side-effects like dytonia etc. Here, we present a case of Escitalopram-induced severe akathisia - a 53year old female, who had developed severe akathisia after taking Escitalopram for a few days. According to the Barnes Akathisia Rating Scale (BARS), her Global Clinical Assessment of Akathisia Score was 5 i.e. severe akathisia. As per Naronjo Adverse Drug Reaction Scale the probability of association of this adverse reaction with Escitalopram was 7 (i.e. probable). Her symptoms continued in spite of prompt discontinuation of the drug. But, she improved rapidly with the use of Propranolol and Clonazepam. On the last follow-up, she was free from any symptoms. As new generation antidepressants are rarely associated with extra-pyramidal symptoms, the recognition of such adverse effects requires a high index of suspicion. Early recognition of the symptoms and discontinuation of the offending agent along with supportive therapy like a short course of benzodiazepines, beta-adrenergic antagonists or anticholinergics may rapidly relieve the patient from this distressing symptom.

    Objectives. The aim of this systematic review is to study the causes of odontogenic chronic maxillary rhinosinusitis (CMRS), the average age of the patients, the distribution by sex, and the teeth involved. Materials and Methods. We performed an EMBASE-, Cochrane-, and PubMed-based review of all of the described cases of odontogenic CMRS from January 1980 to January 2013. Issues of clinical relevance, such as the primary aetiology and the teeth involved, were evaluated for each case. Results. From the 190 identified publications, 23 were selected for a total of 674 patients following inclusion criteria. According to these data, the main cause of odontogenic CMRS is iatrogenic, accounting for 65.7% of the cases. Apical periodontal pathologies (apical granulomas, odontogenic cysts, and apical periodontitis) follow them and account for 25.1% of the cases. The most commonly involved teeth are the first and second molars. Conclusion. Odontogenic CMRS is a common disease that must be suspected whenever a patient undergoing dental treatment presents unilateral maxillary chronic rhinosinusitis. PMID:24817890

    The purpose of this study was to firstly present the maiden case of tamoxifen-induced acute cutaneous lupus erythematosus (ACLE), and secondly, to broaden the discussion into a systematic review of the various tamoxifen-related skin changes documented in patients with breast cancer. We searched PubMed, Cochrane, Embase, CancerLit, Scopus, Web of Science, and Google Scholar databases using keywords to identify reported cases of tamoxifen-related cutaneous adverse events. Outcomes captured included type of cutaneous reaction, time to adverse event, pathologic mechanism, and possible treatment. From 17 clinical studies identified, over ten distinct types of adverse reactions of the skin were itemized. The character of these cutaneous events ranged from the relatively common hot flashes to the rare, but potentially life-threatening, Steven Johnson syndrome. Overall, tamoxifen is generally a well-tolerated hormone therapy with decades of supporting safety data. Based on current medical literature, we present the first case of tamoxifen-induced ACLE. Our clinical experience of managing this case revealed that despite its broad use and the frequency of associated skin reactions, there is a lack of concise information detailing the cutaneous adverse events associated with tamoxifen. The absence of summarized information concerning tamoxifen-related skin changes prompted us to perform a review herein. PMID:25292419

    Although Streptococcus pneumoniae is an important pathogen of humans, pneumococcal cholangitis is rare because of the rapid autolysis of S. pneumoniae. The aim of this case series was to review patients with bile cultures positive for S. pneumoniae. This study was a single center retrospective case series review of patients with S. pneumoniae in their bile at a tertiary-care cancer center between September 2002 and August 2015. Subjects consisted of all patients in whom S. pneumoniae was isolated in their bile during the study period. Bile specimens for culture were obtained from biliary drainage procedures such as endoscopic retrograde biliary drainage, endoscopic nasobiliary drainage, and percutaneous transhepatic biliary drainage. There were 20 patients with bile cultures positive for S. pneumoniae during the study period. All patients presented with extrahepatic obstructive jaundice due to hepatopancreatobiliary tumors. Nineteen of 20 patients underwent the placement of plastic intrabiliary tubes. The mean time between the first-time drainage and the positive culture was 26 days (range 0-313 days). Although 12 of 20 patients met our definition of cholangitis, 5 were clinically treated with antibiotics based on a physician's assessment of whether there was a true infection. The present study is the largest case series of patients with S. pneumoniae in their bile. Based on our findings, the isolation of S. pneumoniae from bile may be attributed to the placement of biliary drainage devices. PMID:27025902

    2015-01-01

    This work aims to facilitate diagnosing Aspergillus appendicitis, which can be missed clinically due to its rarity, by proposing a clinical pentad for Aspergillus appendicitis based on literature review and one new case. The currently reported case of pathologically-proven Aspergillus appendicitis was identified by computerized search of pathology database at William Beaumont Hospital, 1999-2014. Prior cases were identified by computerized literature search. Among 10980 pathology reports of pathologically-proven appendicitis, one case of Aspergillus appendicitis was identified (rate = 0.01%). A young boy with profound neutropenia, recent chemotherapy, and acute myelogenous leukemia presented with right lower quadrant pain, pyrexia, and generalized malaise. Abdominal computed tomography scan showed a thickened appendiceal wall and periappendiceal inflammation, suggesting appendicitis. Emergent laparotomy showed an inflamed, thickened appendix, which was resected. The patient did poorly postoperatively with low-grade-fevers while receiving antibacterial therapy, but rapidly improved after initiating amphotericin therapy. Microscopic examination of a silver stain of the appendectomy specimen revealed fungi with characteristic Aspergillus morphology, findings confirmed by immunohistochemistry. Primary Aspergillus appendicitis is exceptionally rare, with only 3 previously reported cases. All three cases presented with (1)-neutropenia, (2)-recent chemotherapy, (3)-acute leukemia, and (4)-suspected appendicitis; (5)-the two prior cases initially treated with antibacterial therapy, fared poorly before instituting anti-Aspergillus therapy. The current patient satisfied all these five criteria. Based on these four cases, a clinical pentad is proposed for Aspergillus appendicitis: clinically-suspected appendicitis, neutropenia, recent chemotherapy, acute leukemia, and poor clinical response if treated solely by antibacterial/anti-candidial therapy.

    AIM: To investigate the clinical presentation, diagnosis, and treatment of giant colonic diverticulum (GCD, by means of a complete and updated literature review). GCD is a rare manifestation of diverticular disease of the colon. Less than 200 studies on GCD were published in the literature, predominantly case reports or small patient series. METHODS: A systematic review of the literature was performed using the Embase and PubMed databases to identify all the GCD studies. The following MESH search headings were used: “giant colonic diverticulum”; “giant sigmoid diverticulum”. The “related articles” function was used to broaden the search, and all of the abstracts, studies, and citations were reviewed by two authors. The following outcomes were of interest: the disease and patient characteristics, study design, indications for surgery, type of operation, and post-operative outcomes. Additionally, a subgroup analysis of cases treated in the last 5 years was performed to show the current trends in the treatment of GCD. A GCD case in an elderly patient treated in our department by a sigmoidectomy with primary anastomosis and a diverting ileostomy is presented as a typical example of the disease. RESULTS: In total, 166 GCD cases in 138 studies were identified in the literature. The most common clinical presentation was abdominal pain, which occurred in 69% of the cases. Among the physical signs, an abdominal mass was detected in 48% of the cases, whereas 20% of the patients presented with fever and 14% with abdominal tenderness. Diagnosis is based predominantly on abdominal computed tomography. The most frequent treatment was colic resection with en-bloc resection of the diverticulum, performed in 57.2% of cases, whereas Hartmann’s procedure was followed in 11.4% of the cases and a diverticulectomy in 10.2%. An analysis of sixteen cases reported in the last 5 years showed that the majority of patients were treated with sigmoidectomy and en-bloc resection of

  12. Cost of dengue outbreaks: literature review and country case studies

    PubMed Central

    2013-01-01

    Background Dengue disease surveillance and vector surveillance are presumed to detect dengue outbreaks at an early stage and to save – through early response activities – resources, and reduce the social and economic impact of outbreaks on individuals, health systems and economies. The aim of this study is to unveil evidence on the cost of dengue outbreaks. Methods Economic evidence on dengue outbreaks was gathered by conducting a literature review and collecting information on the costs of recent dengue outbreaks in 4 countries: Peru, Dominican Republic, Vietnam, and Indonesia. The literature review distinguished between costs of dengue illness including cost of dengue outbreaks, cost of interventions and cost-effectiveness of interventions. Results Seventeen publications on cost of dengue showed a large range of costs from 0.2 Million US$ in Venezuela to 135.2 Million US$ in Brazil. However, these figures were not standardized to make them comparable. Furthermore, dengue outbreak costs are calculated differently across the publications, and cost of dengue illness is used interchangeably with cost of dengue outbreaks. Only one paper from Australia analysed the resources saved through active dengue surveillance. Costs of vector control interventions have been reported in 4 studies, indicating that the costs of such interventions are lower than those of actual outbreaks. Nine papers focussed on the cost-effectiveness of dengue vaccines or dengue vector control; they do not provide any direct information on cost of dengue outbreaks, but their modelling methodologies could guide future research on cost-effectiveness of national surveillance systems. The country case studies – conducted in very different geographic and health system settings - unveiled rough estimates for 2011 outbreak costs of: 12 million US$ in Vietnam, 6.75 million US$ in Indonesia, 4.5 million US$ in Peru and 2.8 million US$ in Dominican Republic (all in 2012 US$). The proportions of the

    Protein docking algorithms aim to calculate the three-dimensional (3D) structure of a protein complex starting from its unbound components. Although ab initio docking algorithms are improving, there is a growing need to use homology modeling techniques to exploit the rapidly increasing volumes of structural information that now exist. However, most current homology modeling approaches involve finding a pair of complete single-chain structures in a homologous protein complex to use as a 3D template, despite the fact that protein complexes are often formed from one or more domain-domain interactions (DDIs). To model 3D protein complexes by domain-domain homology, we have developed a case-based reasoning approach called KBDOCK which systematically identifies and reuses domain family binding sites from our database of nonredundant DDIs. When tested on 54 protein complexes from the Protein Docking Benchmark, our approach provides a near-perfect way to model single-domain protein complexes when full-homology templates are available, and it extends our ability to model more difficult cases when only partial or incomplete templates exist. These promising early results highlight the need for a new and diverse docking benchmark set, specifically designed to assess homology docking approaches. PMID:24123156

    The present study was performed to report 15 anisakiasis cases in Korea and to review the Korean cases reported in the literature. Total 32 Anisakis type I larvae were detected in the stomach of 15 patients by the endoscopy. Single worm was detected from 12 cases, and even 9 larvae were found from 2 cases. Epigastric pain was most commonly manifested in almost all cases, and hemoptysis and hematemesis were seen in 1 case each. Symptom manifestations began at 10-12 hr after eating fish in 73.3% cases. Endoscopy was performed 1-2 days after the symptom onset in most cases. The common conger, Conger myriaster, was the probable infection source in 7 cases. In the review of Korean anisakiasis cases, thus far, total 645 cases have been reported in 64 articles. Anisakis type I larva was the most frequently detected (81.3%). The favorable infection site of larvae was the stomach (82.4%). The common conger was the most probable source of human infections (38.6%). Among the total 404 cases which revealed the age and sex of patients, 185 (45.8%) were males, and the remaining 219 (54.2%) were female patients. The age prevalence was the highest in forties (34.7%). The seasonal prevalence was highest in winter (38.8%). By the present study, 15 cases of gastric anisakiasis are added as Korean cases, and some epidemiological characteristics of Korean anisakiasis were clarified. PMID:26323845

    Trichoepitheliomas (TE) are benign tumours but occasionally can undergo transformation to malignant neoplasms more commonly as Basal Cell Carcinoma (BCC). The correct diagnosis between these tumours is very important because basal cell carcinoma is locally aggressive neoplasm and requires total surgical excision with wide healthy margins while trichoepithelioma needs simple excision. We describe three patients who developed basal cell carcinoma with facial trichoepitheliomas. The only clinical feature that distinguished the carcinomas from the trichoepitheliomas was their larger size, in all three patients, one patient with recurrent, hyper pigmented swelling with surface ulceration and in another patient there are multiple trichoepitheliomas, and other family members are also affected. The history, clinical features and histopathological findings were suggestive of the evolution of basal cell carcinoma directly from trichoepithelioma in our first two cases, but in the third case TE and BCC were separate lesions on face and we are uncertain about whether the BCC developed independently or by transformation from a trichoepithelioma. Based on our clinicopathological observations in the three patients and reports in the recent literature, BCC with follicular differentiation and trichoepithelioma are considered to be highly related.

    We report a case of Goodpasture's syndrome following chronic low level and an acute, high level of exposure to crystalline silica. A 38-year-old male tilesetter was admitted to the emergency room with dyspnea and respiratory failure. He reported that his symptoms had developed over the previous week after inhaling a large amount of dust while dry-sanding and sweeping a silica-based product used to fill cracks in a cement floor. Over the following days, his pulmonary function declined and he developed acute renal failure. Tests of antiglomerular basement membrane antibody were positive and renal biopsy revealed global glomerulonephritis. He was diagnosed with Goodpasture's syndrome and treated with steroids, plasmapheresis, and hemodialysis. This man had a history of childhood asthma and a remote, one pack-year history of cigarette use. He used the flooring product for seven years prior to the inciting event, however, previous jobs had utilized significantly smaller amounts. Goodpasture's syndrome and other autoimmune diseases have been reported in association with silica exposure. The acute onset following high level silica exposure in this previously healthy man, suggest that clinicians should investigate silica exposure as a causal factor in cases of Goodpasture's syndrome.

    The aim of this study was to retrospectively analyze the cases of six infants with incontinentia pigmenti (IP) in the Department of Neonates and compare their data with 60 cases of IP reported in the available Chinese literature, in order to determine the clinical characteristics and outcomes of neonatal IP in China. The majority of the cases were located near the eastern and southern coasts of China, and ~98.5% of IP cases occurred within 1 week of birth. The majority of the babies with IP were term infants. Twelve cases had a positive family history of IP. The mothers of 10 patients had a history of recurrent spontaneous abortions, and the mothers of five patients had infectious or autoimmune diseases during pregnancy. Cutaneous manifestations were shown at stage I in 59 cases, at stage II in 28 cases and at stage III in three cases (multiple stages were recorded in certain cases). Neurological changes occurred in 18 cases and ocular changes were observed in 12 cases. The toxoplasmosis, rubella, cytomegalovirus and herpes simplex (TORCH) test showed positive results in three cases; autoantibody positivity was found in three cases and high blood eosinophil levels were observed in 20 cases. Brain scans revealed positive results in 16 cases and complications were observed in 21 cases. Thirty-four cases were followed for 1-6 months, six cases for 7-12 months and 17 cases for 13-84 months. Among these cases, 34 exhibited no evidence of recurrence. Five patients, including one male, succumbed in the long course of the follow-up. Two IP cases persisted after five years of follow-up. The data from the present study may reflect the characteristics of IP in the Chinese population and provide useful information for the diagnosis and treatment of IP by dermatologists and neonatologists.

    Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare and difficult to distinguish from other liver tumors, such as hepatocellular carcinoma (HCC) and cholangiocarcinoma, based on medical imaging findings. A 70-year-old man was referred for evaluation of liver mass incidentally discovered on abdominal computed tomography. The characteristic finding from dynamic liver magnetic resonance imaging led to a diagnosis of HCC. The patient underwent right hepatectomy. Histopathological and immunohistochemical examination revealed grade 2 neuroendocrine tumor. The postoperative 24-h urinary excretion of 5-hydroxy-indolacetic acid was within the normal range. Further imaging investigations were performed. No other lesions were found making probable the diagnosis of PHNET. This case shows that the diagnosis of PHNET is a medical challenge, requiring differentiation of PHNETs other hepatic masses and exclusion of occult primary neuroendocrine tumors. The diagnosis of PHNET can be ascertained after long term follow-up to exclude another primary origin. PMID:27574614

    Mandibular exostosis is a type of bony prominence caused due to hyperostosis in the mandibular bone. They are benign, broad-based surface masses on the outer or facial aspect of the jaw bones; slowly enlarge over the years to form the bulky masses. During the period between the 10th to 13th week of intrauterine life, changes in the structure of the Meckel’s cartilage and the protrusion of the medial lamina of the mandible onto the cartilage can result in the formation of such exostosis. We discuss here a very rare case of a 49-year-old male, in which the buccal exostoses formed underwent changes in size and shape due to certain factors, resulting in a bony bar formation in the mandibular anterior region.

    Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by proliferation of bone marrow derived Langerhans cells and mature eosinophils. Their clinical features simulate common oral findings such as gingival enlargement, oral ulcers, and mobility of teeth, along with nonspecific radiographic features; hence, diagnosing such lesions becomes difficult for the oral physicians. These lesions are commonly seen in childhood; however, we are reporting a case of LCH in 29-year-old adult male. A provisional diagnosis of giant cell granuloma was considered based on history and examination, although the lesion was histologically proven to be LCH and was confirmed with immunohistochemical staining of S100 protein and CD1a antigen. The purpose of this paper is to enhance the understanding of diverse, nonpathognomical oral presentation of LCH that is easily misdiagnosed and overlooked by dentist. PMID:26321851

    A recent case of seal finger which was misdiagnosed and hence mistreated at the patient’s first presentation is described. The patient was eventually referred to a hand specialist and after the correct treatment with tetracycline, responded well without any long-term sequelae. Seal finger is an occupational injury that occurs to those who work directly or indirectly with seals. The disease entity has been described in both Scandinavian and Canadian literature. The causative microorganism was unknown until 1991, when Mycoplasma phocacerebrale was isolated from both the finger of a patient with seal finger and from the mouth of a seal that bit the patient. Although rare, the disease is not uncommon in marine workers, biologists and veterinarians. Prompt identification based on patient history and treatment with oral tetracycline is pendant to a favourable patient outcome. PMID:21119845

    Objective: To review systematically medical-legal cases of sleep-related violence (SRV) and sexual behavior in sleep (SBS). Search Methods: We searched Pubmed and PsychINFO (from 1980 to 2012) with pre-specified terms. We also searched reference lists of relevant articles. Selection Criteria: Case reports in which a sleep disorder was purported as the defense during a criminal trial and in which information about the forensic evaluation of the defendant was provided. Data Extraction and Analysis: Information about legal issues, defendant and victim characteristics, circumstantial factors, and forensic evaluation was extracted from each case. A qualitative-comparative assessment of cases was performed. Results: Eighteen cases (9 SRV and 9 SBS) were included. The charge was murder or attempted murder in all SRV cases, while in SBS cases the charge ranged from sexual touching to rape. The defense was based on sleepwalking in 11 of 18 cases. The trial outcome was in favor of the defendant in 14 of 18 cases. Defendants were relatively young males in all cases. Victims were usually adult relatives of the defendants in SRV cases and unrelated young girls or adolescents in SBS cases. In most cases the criminal events occurred 1-2 hours after the defendant's sleep onset, and both proximity and other potential triggering factors were reported. The forensic evaluations widely differed from case to case. Conclusion: SRV and SBS medical-legal cases did not show apparent differences, except for the severity of the charges and the victim characteristics. An international multidisciplinary consensus for the forensic evaluation of SRV and SBS should be developed as an urgent priority.

    The forehead is a unique facial region with distinct boundaries and variability in shape from patient to patient. When reconstructing the forehead, it is critical to take into account the regional boundaries as their distortion may result in noticeable facial asymmetry. We propose subdividing the forehead into newly defined zones and put forth a rational algorithm for forehead repair based on these divisions. We retrospectively reviewed a single surgeon's (F. H. S.) experience with Mohs excision and immediate reconstruction of the forehead over a 3-year period. A total of 227 consecutive post-Mohs forehead reconstructions were identified, and the reconstructive technique for a given defect size and location and postoperative complications were recorded. The average patient age was 69 years and 114 (50%) patients were female. Reconstructive techniques varied based on defect size and location within the five distinct forehead zones. Primary closure was the favored technique when appropriate, with variation in orientation based on forehead zone. Modified Burow's advancement flap was the most commonly utilized reconstruction for defects of midlateral forehead and suprabrow area, accounting for 51.7 and 62.5% of repairs, respectively. Other techniques included A-to-T flaps, rotation flaps, and full-thickness skin grafting. Using our defined zones, most common repair techniques, and final outcomes, a reconstructive algorithm for post-Mohs excisions on the forehead was derived. Consideration of the five distinct forehead zones and application of an algorithm to guide technique selection for post-Mohs forehead defect repair can lead to consistent results. PMID:27248030

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC. PMID:27457076

    Biosensors are a very active research field. They have the potential to lead to low-cost, rapid, sensitive, reproducible, and miniaturized bioanalytical devices, which exploit the high binding avidity and selectivity of biospecific binding molecules together with highly sensitive detection principles. Of the optical biosensors, those based on chemical luminescence detection (including chemiluminescence, bioluminescence, electrogenerated chemiluminescence, and thermochemiluminescence) are particularly attractive, due to their high-to-signal ratio and the simplicity of the required measurement equipment. Several biosensors based on chemical luminescence have been described for quantitative, and in some cases multiplex, analysis of organic molecules (such as hormones, drugs, pollutants), proteins, and nucleic acids. These exploit a variety of miniaturized analytical formats, such as microfluidics, microarrays, paper-based analytical devices, and whole-cell biosensors. Nevertheless, despite the high analytical performances described in the literature, the field of chemical luminescence biosensors has yet to demonstrate commercial success. This review presents the main recent advances in the field and discusses the approaches, challenges, and open issues, with the aim of stimulating a broader interest in developing chemical luminescence biosensors and improving their commercial exploitation.

    Objectives: Otophyma is a rare condition that can present as the end stage of any chronic inflammatory disease affecting the ear such as rosacea, eczema, or otitis externa. It can result in conductive hearing loss, low self-esteem, and social embarrassment. This report highlights a case of otophyma treated successfully using a full-thickness skin graft. Methods: We present a case of a 41-year-old lady referred to our department with a 23-year history of bilateral otophyma. During this time, her hearing progressively diminished as the swelling occluded her external auditory meatus. She had been unsuccessfully managed for years with topical emollients, steroids, and regular ear toileting. Result: She was treated by excision of the phymatous tissue and full-thickness grafting, which resulted in a patent external auditory meatus and an improvement in her hearing. Conclusions: The use of a full-thickness skin graft is one of the many treatment options available for the treatment of otophyma. We present a literature review on this uncommon condition and a discussion on the various treatment options available to the patient. PMID:23641297

    Background Lobular capillary hemangioma (LCH) is an acquired benign vascular tumor of unknown origin. It usually affects skin and mucous membranes of the oropharynx. It rarely involves the nasal cavity which most commonly manifests as epistaxis. To our knowledge, only fifteen pediatric intranasal LCH cases have been reported in the literature. None of these occurred in the inferior turbinate. We report two new pediatric cases of LCH, one of them on the inferior turbinate and the other one on the anterior nasal septum. Our principal aim was to highlight the importance of considering this lesion as a differential diagnosis for pediatric unilateral nasal obstruction and epistaxis. Methods Retrospective case series and review of current literature regarding the possible causes, diagnosis, and treatment of nasal LCH. Description of cases Two adolescents presented with symptoms of unilateral nasal obstruction and epistaxis. Plain and contrast enhanced computed tomography revealed a well-defined intensely enhancing lesion in both cases. Patients underwent transnasal endoscopic excision and bipolar electrocautery at the base of the tumor for hemostasis. Histopathological examination confirmed the diagnosis of LCH. Discussion Current epidemiological and pathophysiological data suggests that the development of LCH may be associated to previous nasal trauma or endocrine disorders. LCH should be considered in the differential diagnosis of all pediatric endonasal masses associated with unilateral epistaxis and nasal obstruction. Endoscopic total excision with bipolar electrocautery for hemostasis is an appropriate treatment. PMID:27144115

    Blood culture is often used in definitive diagnosis of typhoid fever while, bone marrow culture has a greater sensitivity and considered reference standard. The sensitivity of blood culture measured against bone marrow culture results in measurement bias because both tests are not fully sensitive. Here we propose a combination of the two cultures as a reference to define true positive S. Typhi cases. Based on a systematic literature review, we identified ten papers that had performed blood and bone marrow culture for S. Typhi in same subjects. We estimated the weighted mean of proportion of cases detected by culture measured against true S. Typhi positive cases using a random effects model. Of 529 true positive S. Typhi cases, 61 % (95 % CI 52-70 %) and 96 % (95 % CI 93-99 %) were detected by blood and bone marrow cultures respectively. Blood culture sensitivity was 66 % (95 % CI 56-75 %) when compared with bone marrow culture results. The use of blood culture sensitivity as a proxy measure to estimate the proportion of typhoid fever cases detected by blood culture is likely to be an underestimate. As blood culture sensitivity is used as a correction factor in estimating typhoid disease burden, epidemiologists and policy makers should account for the underestimation. PMID:27188991

    Since the 1970s, modern Implantology is based on a concept of surgery with flap elevation. Gradually, several clinical trials demonstrated that a mid-crestal incision gives similar success rates compared to those obtained using the classical protocol. However, over the past decade in medicine it has been established the concept of minimally invasive surgery, consisting in taking advantage of advancements experienced in diagnostic techniques and specific surgical instruments, to perform surgical procedures infringing as less damage as possible to the patient The present work aims to produce a thorough review of the literature published on the field of Implantology with flapless surgery, to determine the current scientific evidence of the technique, along with illustrating the results with different clinical cases. After presenting the clinical cases, and the review of literature, we can say that flapless surgeries should be restricted to well-selected cases in which a proper clinical and radiological planning has been made. Patients treated with anticoagulant drugs or medically compromised equally can get benefitted by this minimal invasion technique. Key words:Flapless, minimally invasive surgery, dental implant.

    The aim of this study is to review four case-based scenarios regarding the treatment of symptomatic hypogonadism in men. The article is designed as a review of published literature. We conducted a PubMed literature search for the time period of 1989-2014, concentrating on 26 studies investigating the efficacy of various therapeutic options on semen analysis, pregnancy outcomes, time to recovery of spermatogenesis, as well as serum and intratesticular testosterone levels. Our results demonstrated that exogenous testosterone suppresses intratesticular testosterone production, which is an absolute prerequisite for normal spermatogenesis. Cessation of exogenous testosterone should be recommended for men desiring to maintain their fertility. Therapies that protect the testis involve human chorionic gonadotropin (hCG) therapy or selective estrogen receptor modulators (SERMs), but may also include low dose hCG with exogenous testosterone. Off-label use of SERMs, such as clomiphene citrate, are effective for maintaining testosterone production long-term and offer the convenience of representing a safe, oral therapy. At present, routine use of aromatase inhibitors is not recommended based on a lack of long-term data. We concluded that exogenous testosterone supplementation decreases sperm production. It was determined that clomiphene citrate is a safe and effective therapy for men who desire to maintain fertility. Although less frequently used in the general population, hCG therapy with or without testosterone supplementation represents an alternative treatment. PMID:25949938

    Wegener Granulomatosis (WG) is a multisystem autoimmune disorder characterized by necrotizing granulomatous vasculitis that most commonly involves the upper respiratory tract, lungs, and kidneys. The involvement of the central nervous system (CNS) is infrequent and can cause stroke, cranial nerve abnormalities, cerebrovascular events, seizures, and meningeal involvement. Meningeal involvement is rare and may occur due to local vasculitis, directly spread from adjacent disease in the skull base, paranasal or orbital region. We describe the case of a 20-year-old Caucasian man who was diagnosed with sinonasal WG with frontal focal meningeal involvement. A literature review on diagnosis and treatment of meningeal involvement in course of WG was carried out. The importance of an early diagnosis and treatment of localized WG has been emphasized, in order to avoid the progression to a severe form of disease, especially in younger patients and in paucisymptomatic cases.

    Noonan syndrome (NS) was described by Noonan and Ehmke as a multi-system disorder, which is typically evident at birth. The incidence of this syndrome is estimated to be one per 2500 to one per 1000 and affects both genders. While the clinical manifestations of NS have been well documented, the oral manifestations have not been extensively discussed. The purpose of the present article is to (a) review the oral manifestations of NS reported in the literature, and (b) describe four cases (three females and one male) of NS, who presented with short stature, cardiac problems and various oral findings. Based on these cases, we conclude that many oral anomalies may have possible relationships with NS, which require multidisciplinary treatment planning and timely management. The importance of oral findings in NS has largely gone unnoticed and it is essential to consider oral manifestations as scoring criteria in the diagnosis of NS. PMID:25611289

    Desmoid tumors, also known as desmoid-type fibromatoses or aggressive fibromatoses, are clonal fibroblastic proliferations that arise in the deep soft tissues. They are characterized by infiltrative growth, a tendency toward local recurrence and the inability to metastasize. We present a case of a 63-year-old woman who complained of abdominal pain, and a contrast-enhanced computed tomography scan revealed a well-circumscribed tumor in the pancreatic tail, measuring 5.1 cm. A left-sided, spleen-preserving pancreatic resection was performed, and pathological analysis showed a mesenchymal tumor. The diagnosis of a pancreatic desmoid tumor was made based on the characteristic morphology and the immune phenotype of the tumor. The English-language literature on pancreatic desmoid tumors was reviewed. In total, 16 previous cases were identified. PMID:26215223

    Sclerosing angiomatoid nodular transformation (SANT) is a rare benign splenic vascular lesion. Since it was first defined in 2004, a total of 132 cases of SANT have been reported in ~50 studies in the English literature. However, it remains difficult to form a definitive pre-operative differential diagnosis of SANT compared with other splenic tumors or malignant lesions. The present study reports a pathologically proven case of SANT in a 29-year-old man who initially presented with left upper quadrant and back discomfort. The study also provides a review of the current knowledge on the condition, including the clinical profile, imaging features, cytological features, differential diagnosis and treatment of SANT. The most important distinguishing features of SANT are its typical vascular character and lack of other features that are typical of a granuloma. A splenectomy is required and the diagnosis is based on pathological analysis. PMID:27446372

  7. [Role of psychiatrists in capital punishment cases : a review].

    PubMed

    2002-01-01

    Many medical organizations have passed resolutions banning participation of psychiatrists in legal executions, such as the Madrid Declaration of World Psychiatric Association. The Criminal Procedure Act of Japan prohibits the execution of the insane. Although the USA and Japan are both among the few so-called developed countries that have a system of capital punishment, many disputes about psychiatrists' participation in death penalty cases have occurred in the US, but few in Japan. This author has reviewed papers addressing this issue. The U.S. Supreme Court decided in Ford v. Wainwright that the execution of an "insane" inmate was not constitutional. The rationale for excluding the mentally incompetent from execution, however, is not completely clear. The most compelling reason is that execution does not satisfy the requirement for "effective retribution," since the insane criminal is not capable of understanding the implications of the death penalty. Nonetheless, there are those who dispute this interpretation and offer other explanations. Psychiatrists may be called upon to assess a criminal's competency for execution. Some find no problem with this practice, while others object to it stating that it conflicts with the ethical tenet to "first do no harm." Those who argue from a middle position insist on assessing competency while recognizing the existence of problems in making such an assessment. Furthermore, there is controversy over which factors exactly constitutes "competency to be executed." Usually, it is thought to be one's capacity to understand the nature of the death penalty and the reasons why the penalty is to be inflicted, but other arguments exist, including the capacity to assist legal counsel in last minute appeals. The question of whether to offer treatment to death row inmates who have been found incompetent to be executed is also under debate. The first position argues that they should "never be treated", because such prisoners would be

    Many European countries are faced with health workforce shortages and the need to develop effective recruitment and retention (R&R) strategies. Yet comparative studies on R&R in Europe are scarce. This paper provides an overview of the measures in place to improve the R&R of health professionals across Europe and offers further insight into the evidence base for R&R; the interaction between policy and organisational levels in driving R&R outcomes; the facilitators and barriers throughout these process; and good practices in the R&R of health professionals across Europe. The study adopted a multi-method approach combining an extensive literature review and multiple-case study research. 64 publications were included in the review and 34 R&R interventions from 20 European countries were included in the multiple-case study. We found a consistent lack of evidence about the effectiveness of R&R interventions. Most interventions are not explicitly part of a coherent package of measures but they tend to involve multiple actors from policy and organisational levels, sometimes in complex configurations. A list of good practices for R&R interventions was identified, including context-sensitivity when implementing and transferring interventions to different organisations and countries. While single R&R interventions on their own have little impact, bundles of interventions are more effective. Interventions backed by political and executive commitment benefit from a strong support base and involvement of relevant stakeholders. PMID:26324418

    Staphylococcus intermedius is part of the normal skin and oral flora of dogs. Case reports of human infections are rare, but the true incidence is unknown because the pathogen is frequently misidentified as Staphylococcus aureus. Reported cases range from soft tissue infections to brain abscess. Most reported cases in humans have been related to dog exposure. We report a case of a 73 year old female with S. intermedius surgical wound infection one month following a left elbow total arthroplasty. This is the first reported human case of S. intermedius infection of a mechanical prosthesis. The presumed source of infection was the patient's dog. The patient was treated with vancomycin, then switched to cefazolin and rifampin once susceptibilities were known. Case reports suggest that patients generally respond well to tailored antibiotics with complete or near-complete recovery. S. intermedius should be included in the differential diagnosis of invasive infection amongst patients with close contact with dogs. PMID:24470954

    Red ear syndrome (RES) is characterized by recurrent unilateral or bilateral painful attacks of the external ear, accompanied by ear redness, burning, or warmth. Proposed etiologies of this rare condition include dysregulation of sympathetic outflow, upper cervical pathology, glossopharyngeal and trigeminal neuralgia, TMJ dysfunction, thalamic syndrome, and primary headache syndromes. Idiopathic cases also exist in the literature. Pediatric cases are particularly rare and more commonly associated with migraine. Given the various potential etiologies, no single treatment is effective in all cases. This paper summarizes the current understanding and management of RES, and describes a case of idiopathic pediatric RES. PMID:25583087

    2016-01-01

    Abstract Pulmonary arterial hypertension (PAH) is a known complication of rheumatologic diseases, but it is only rarely associated with adult-onset Still’s disease (AOSD). We describe the case of a 30-year-old woman who presented in a pulmonary hypertension crisis and was found to have underlying AOSD with PAH and nonspecific interstitial pneumonia (NSIP) with a course complicated by macrophage activation syndrome (MAS). She dramatically improved with steroids, cyclosporine A, and anakinra, with total resolution of the MAS and significant improvement of her pulmonary arterial pressures. While there are only select case reports of AOSD associated with PAH, this is the first reported case of (1) AOSD complicated by both PAH and MAS and (2) AOSD complicated by biopsy-proven NSIP. Clinically, this case highlights the efficacy of immunosuppressive agents in the treatment of PAH and MAS from underlying AOSD and supports their use in this setting. PMID:27162622

    Summary Background Penile involvement is a rare, self-limiting, benign genital condition. In Mondor’s disease the underlying pathology is thrombophlebitis of a superficial vein. Case Report In this case report, we want to present a rare Penile Mondor’s disease with literature review. Conclusions While the diagnosis can be based on history, physical examination and Doppler ultrasound, the necessity of both MRI, MR angiography and intracavernosal vasoactive agent administration can be questioned. Both MRI and intravenous vasoactive agent administration may be helpful in suspicious cases for differential diagnosis and to eliminate other etiologies like pelvic mass or thrombosis. PMID:26893793

    Infective endocarditis (IE) incidence remains high with considerable fatality rates; guidelines for prophylaxis against IE are currently under review in some settings which highlights the importance of maintaining up-to-date epidemiological estimates about the most common microbial causes. The objective of this systematic review, following PRISMA guidelines, was to identify the most common microbial causes of IE in recent years. Medline was searched from January 1, 2003 to March 31, 2013 for all articles containing the term "infective endocarditis". All relevant studies reporting diagnostic results were included. Special patient subpopulations were assessed separately. A total of 105 studies were included, from 36 countries, with available data on a total of 33,214 cases. Staphylococcus aureus was found to be the most common microorganism, being the most frequent in 54.3 % of studies (N = 57) (and in 55.4 % of studies using Duke's criteria for diagnosis [N = 51]). Viridans group streptococci (VGS), coagulase-negative staphylococci (CoNS), Enterococcus spp and Streptococcus bovis were among the most common causes. S. aureus was the most common pathogen in almost all population subgroups; however, this was not the case in patients with implantable devices, prosthetic valves, or immunocompromised non-HIV, as well as in the sub-group from Asia, emphasizing that a global one-size-fits-all approach to the management of suspected IE is not appropriate. This review provides an evidence-based map of the most common causative agents of IE, highlighting S. aureus as the leading cause in the 21st century. The changing epidemiology of IE in some patient sub-groups in the last decade and the very high number of microbiologically undiagnosed cases (26.6 %) suggest the need to revisit IE prophylaxis and diagnostic strategies.

    Gastroparesis is a syndrome characterized by delayed gastric emptying in the absence of mechanical obstruction. The most common underlying aetiology is diabetes mellitus; however, many cases are idiopathic. Pregnancy per se is associated with gastrointestinal neuromuscular dysfunction; however, reports of gastroparesis arising during pregnancy are rare. We report a case of severe gastroparesis and proximal small bowel paresis presenting during pregnancy.

    A relationship between Takayasu arteritis (TA) and positive antiphospholipid antibody states has been pointed out, but patients with TA complicated with antiphospholipid antibody syndrome (APS) are rare. Here we report the case of a 17-year-old Japanese man diagnosed with TA based on pulselessness of the left brachial artery, discrepancy of blood pressure between the upper extremities, and arterial wall thickening and narrowing of artery in contrast computed tomography. He was also diagnosed with provisional APS based on a pulmonary infarction without narrowing of the pulmonary artery and positive antiphosphatidylserine/prothrombin antibody. The patient also had concurrent Crohn's disease (CD) based on histopathological findings, which may have been associated with TA. We started high-dose corticosteroid therapy and anticoagulation therapy, and his symptoms including fever, dizziness, chest pain, and lower-right uncomfortable abdomen improved.We reviewed 9 cases of TA with APS including our patient by conducting a PubMed search. Based on past reports, we considered the relationship among TA, APS, and CD.Clinicians should bear in mind that many etiologies can exist in 1 patient, and differential diagnoses are essential.

    Homicide-suicides or "dyadic deaths" refer to a homicide followed by the suicide of the perpetrator within 1 week of the homicide. A unique subset is filicide-suicide: a parent kills his/her child before committing suicide. Shooting is the preferred method for both the homicide and suicide. The perpetrator has depression in most cases.We present 3 cases of filicide-suicide. In case 1, a divorced mother with schizophrenia and bipolar disorder shot her son and herself. In case 2, a father shot his son and himself while involved in a child-custody dispute. In case 3, a father, experiencing a divorce and financial difficulties, and his daughter with Angelman syndrome succumbed to carbon monoxide poisoning.The forensic pathologist should be aware of the psychosocial dynamics that interplay in filicide-suicide. Diligent attention to a parent's life stressors may aid in determining risk factors for filicide-suicide. PMID:26087315

    Background Diphallus is an extremely rare anomaly. Numerous associated genitourinary, gastrointestinal and other anomalies have been described with diphallus. These patients need several investigations, and finally surgical intervention. Cases Presentation In this report we discuss six patients with diphallus which evaluated retrospectively. Five patients had complete diphallia, and one had bifid diphallus. Meatus was normal in 3, hypospadiac in 2, and epispadiac in one patient. The most common associated anomaly was bifid scrotum (5 cases), and other common anomalies consisted of bladder duplication (3 cases), imperforate anus (2 cases), and hypospadias (2 cases). Phalloplasty was performed for all but one. Conclusion All the patients with urethral duplication have to be evaluated carefully because of the high incidence of other systemic anomalies.

    Toxicology testing of fatally injured workers is not routinely conducted. We completed a case-series study of 2005–2009 occupational fatalities captured by Iowa’s Fatality Assessment and Control Evaluation (FACE) Program. The goals of our research were to: (1) measure the proportion of FACE cases that undergo toxicology testing, and describe the factors associated with being tested, and (2) measure the rate of positive toxicology tests, the substances identified and the demographics and occupations of victims who tested positive. Case documents and toxicology laboratory reports were reviewed. There were 427 occupational deaths from 2005 to 2009. Only 69% underwent toxicology testing. Younger workers had greater odds of being tested. Among occupational groups, workers in farming, fishing and forestry had half the odds of being tested compared to other occupational groups. Of the 280 cases with toxicology tests completed, 22% (n = 61) were found to have positive toxicology testing. Commonly identified drug classes included cannabinoids and alcohols. Based on the small number of positive tests, older victims (65+ years) tested positive more frequently than younger workers. Management, business, science, arts, service and sales/office workers had proportionately more positive toxicology tests (almost 30%) compared with other workers (18–22%). These results identify an area in need of further research efforts and a potential target for injury prevention strategies. PMID:24240727

    Discal cysts are rare causes of low back pain and radiculopathy. Only few reports in the literature describe these pathologies. In this article, the authors report five cases (3 males and 2 females) of lumbar discal cysts treated surgically by microdiscectomy. These patients were admitted with a history of back pain and/or sciatalgia. Magnetic resonance imaging of the lumbar spine of all patients revealed lumbar discal cysts, causing compression to the spinal dura and roots. All patients were treated by partial hemilaminectomy and microscopic cyst resection. Postoperatively, the complaints showed improvement, and the patients were discharged with no complications. The cases of lumbar discal cysts are described in the literature as individual case reports, therefore; the authors performed a wide systemic review of all these cases published in PubMed and MedLine, including the patients in the present report. The data of all patients were analyzed to obtain statistically based estimated information about the incidence, the epidemiology, the natural history and the optimum management of these lesions.

    Chondromyxoid fibroma (CMF) is an exceedingly rare tumor that represents less than 1% of all primary bone neoplasms. Occurrence in the facial and cranial bones is extremely rare and frequently misdiagnosed. Case Reports We report two cases of CMF, one in the sphenoclival skull base and the other involving the parietal bone in two young female patients. Excision was performed in both cases. Presenting symptoms, treatment, and follow-up are reported. Methods A retrospective review of the literature on cranial CMF was performed. The location, demographics, presenting symptoms, and treatment of all calvarial and skull base CMF cases published since 1990 are summarized. Discussion In our literature review, we found 67 published cases of cranial CMF. Mean age of all calvarial and skull base CMFs at diagnosis was 38.2 years old. Of the cases affecting the cranium, the sinonasal structures were most commonly involved. To our knowledge we report only the second case of CMF involving the parietal bone published in an English-language journal. Total resection is the best treatment, and should be the goal of surgical intervention. Curettage results in high recurrence rates. Radiotherapy in the setting of subtotal resection or recurrence cannot be definitively recommended and needs further investigation. PMID:26929898

    Marcus, Bradley J; Kaplan, Jennifer; Collins, Kim A

    2008-09-01

    Ludwig angina is a rapidly progressing submaxillary, submandibular, and sublingual necrotizing cellulitis of the floor of the mouth that can have lethal consequences due to airway obstruction. Various aerobic and anaerobic microorganisms, and less often fungi, have been implicated to cause Ludwig angina, including oral flora such as streptococci and staphylococci. Early recognition and the use of parenteral antibiotics can prevent mortality and morbidity. We report a case of a 25-year-old white man who was admitted to the hospital by his dentist after being diagnosed with Ludwig angina secondary to periodontal abscesses involving teeth #17 and #32. Although antibiotics were administered, while in the hospital, the decedent had difficulty swallowing and was drooling. He suddenly began to have seizure-like activity thought to be anoxic myoclonus. The decedent was aggressively resuscitated and taken to the operating room for neck exploration and a tracheostomy. Neck exploration revealed severe necrotizing acute inflammation of the deep soft tissues and musculature of the neck. He remained on life support for 7 days until he was declared brain dead. Ludwig angina is a progressive cellulitis that often results in death by asphyxia. Ludwig angina can be complicated by subsequent deep neck infection. The underlying etiologies and common scenarios are examined, and significant autopsy findings and dissecting procedures are discussed. The pathophysiology of Ludwig angina is studied with a review of the current literature. PMID:18725784

    Malignant Mixed Mullerian Tumour of the Ovary (OMMMT), also referred to as carcinosarcoma is a very rare tumour accounting for less than 1% of all ovarian cancers. Due to the rarity of OMMMT, little is known about the disease course and outcome of women with these tumours. It is important to evaluate because of its aggressive behaviour with extremely unfavourable prognosis. These tumours are composed of both malignant epithelial and mesenchymal elements. Current data in the literature is still limited to small case series and case reports, therefore, its optimal treatment is somewhat controversial. In the current report, we introduce a case of OMMMT which was successfully treated with Platinum-based combination chemotherapy after optimal cytoreductive surgery. The clinical manifestations, pathologic characteristics, diagnosis and management of these tumours are reviewed here. Although the most effective treatment is currently unknown, optimal cytoreductive surgery and platinum-based chemotherapy appears to improve the outcomes. Despite the aggressive nature of this tumour and its poor response to the treatment, management works best when cancer is found early. The stage of the disease is the most important prognostic factor. Therefore, the crucial question is how to diagnose the cancer at earlier stages rather than seeking the optimal treatment.

    We report a review of 208 cases of Meckel's diverticulum among pediatric patients from one single institution. One of the aims of this report is to highlight the different diagnostic modalities of Meckel's diverticulum since a majority of cases is undiagnosed prior to surgery. Our review shows 58 cases containing gastric and/or pancreatic heterotopic tissue, including two unique cases. The first case reported is a desmoid tumor arising at the tip of diverticulum, a case that, to our knowledge, has not been previously reported. The second case involves a female patient appearing with an acute abdomen thought to be appendicitis, instead surgery revealed a diverticulum arising from the ileum. The cause of acute abdomen was due to gonococcal infection. In conclusion, we hope that this large series of Meckel's cases will enrich our readers on the differential diagnosis and preoperative diagnostic techniques of Meckels' diverticulum. PMID:27064958

    Perovskite-based photocatalysts are of significant interest in the field of photocatalysis. To date, several perovskite material systems have been developed and their applications in visible light photocatalysis studied. This article provides a review of the visible light (λ > 400 nm) active perovskite-based photocatalyst systems. The materials systems are classified by the B site cations and their crystal structure, optical properties, electronic structure, and photocatalytic performance are reviewed in detail. Titanates, tantalates, niobates, vanadates, and ferrites form important photocatalysts which show promise in visible light-driven photoreactions. Along with simple perovskite (ABO3) structures, development of double/complex perovskites that are active under visible light is also reviewed. Various strategies employed for enhancing the photocatalytic performance have been discussed, emphasizing the specific advantages and challenges offered by perovskite-based photocatalysts. This review provides a broad overview of the perovskite photocatalysts, summarizing the current state of the work and offering useful insights for their future development. PMID:25532834

    Since the introduction of the Prospective Payment System based on Diagnosis Related Groups (DRGs) in the U.S.A., important information technologies are arising. We discuss how Professional Review Organizations, (PROS) are forcing a better control of appropriateness and quality of medical care. Hospitals should have the internal capabilities to perform, at least, the same reviews as performed by the PROs. Concurrent Clinical Review Systems based on DRGs are a special type of information technology that take place during and even before patient hospitalization, therefore allowing an 'on line' monitoring information. Low-cost microcomputers are playing a major role in the popularization of this technology. 'Clinical Review System' is a microcomputer-based software that renders easy and feasible and otherwise complex task. An effort should be made in order to adapt the philosophy underlying this or other similar software to the European needs. PMID:10312511

    Conjoined twins is a phenomenon believed to be caused by either delayed splitting of the fertilized ovum or fusion of the embryonic stem cells. Disorganization of mutant genes is believed to be a cause in some cases. We report a case of stillborn dicephalus tribrachius female conjoined twins with features that are not reported previously in the literature with a single umbilical artery and two urinary bladders. The cause of intrauterine death in this case was probably multi-factorial i.e. severe anemia in the mother, congestive heart failure, complications of obstructed labor and multiple skull fractures.

    Neurothekeoma is a benign nerve sheath tumor, also known as nerve sheath myxoma. It arises from the cutaneous nerves of the head and neck region. In certain cases, neurothekeoma has been reported in the breast, oral cavity, tongue, maxilla, and spinal intradural space. Intracranial neurothekeoma, however, is an extremely rare entity, with only three cases reported in the literature: one in the parasellar region, one in the deep white matter, and another one in the cerebellopontine angle. We present the case of a 40-year-old man with a very large neurothekeoma present in the posterior fossa who had no neurologic deficit on presentation. PMID:23012602

    To retrospectively review our first 20 Contura high dose rate breast cases to improve and refine our standardized procedure and checklists. We prepared in advance checklists for all steps, developed an in-house Excel spreadsheet for second checking the plan, and generated a procedure for efficient contouring and a set of optimization constraints to meet the dose volume histogram criteria. Templates were created in our treatment planning system for structures, isodose levels, optimization constraints, and plan report. This study reviews our first 20 high dose rate Contura breast treatment plans. We followed our standardized procedure for contouring, planning, and second checking. The established dose volume histogram criteria were successfully met for all plans. For the cases studied here, the balloon-skin and balloon-ribs distances ranged between 5 and 43 mm and 1 and 33 mm, respectively; air{sub s}eroma volume/PTV{sub E}val volume≤5.5% (allowed≤10%); asymmetry<1.2 mm (goal≤2 mm); PTV{sub E}val V90%≥97.6%; PTV{sub E}val V95%≥94.9%; skin max dose≤98%Rx; ribs max dose≤137%Rx; V150%≤29.8 cc; V200%≤7.8 cc; the total dwell time range was 225.4 to 401.9 seconds; and the second check agreement was within 3%. Based on this analysis, more appropriate ranges for the total dwell time and balloon diameter tolerance were found. Three major problems were encountered: balloon migration toward the skin for small balloon-to-skin distances, lumen obstruction, and length change for the flexible balloon. Solutions were found for these issues and our standardized procedure and checklists were updated accordingly. Based on our review of these cases, the use of checklists resulted in consistent results, indicating good coverage for the target without sacrificing the critical structures. This review helped us to refine our standardized procedure and update our checklists.

    Based on an analysis of the interaction of fuel physical and chemical properties with combustion characteristics and indicators, a ranking of the importance of various fuel properties with respect to the combustion process was established. This ranking was used to define a suite of specific experiments whose objective is the development of an alternative fuels design data base. Combustion characteristics and indicators examined include droplet and spray formation, droplet vaporization and burning, ignition and flame stabilization, flame temperature, laminar flame speed, combustion completion, soot emissions, NOx and SOx emissions, and the fuels' thermal and oxidative stability and fouling and corrosion characteristics. Key fuel property data is found to include composition, thermochemical data, chemical kinetic rate information, and certain physical properties.

    2016-01-01

    Summary Primary ovarian insufficiency (POI) is the condition of intermittent or permanent gonadal insufficiency that occurs in women before the age of 40. We describe three cases of POI referred to the outpatient endocrinology clinic of a university hospital. The three patients met diagnostic criteria for POI and were managed by specific approaches tailored to individualized goals. In the first case, the main concern was fertility and the reproductive prognosis. The second patient was a carrier of a common genetic cause of POI: premutation of the FMR1 gene. The third case was a patient diagnosed with a POI and established osteoporosis, a common complication of estrogen deprivation. This study reports the treatment and follow-up of these cases, with an emphasis on relevant aspects of individualized management, alongside a brief literature review. Learning points A diagnosis of POI should be considered in patients presenting with amenorrhea or irregular menses and high serum follicle-stimulating hormone (FSH) levels before age 40 years. Patients with POI without an established cause, especially in familial cases, should be tested for FMR1 mutations. Estrogen/progestin replacement therapy is indicated since diagnosis until at least the estimated age of menopause, and is the cornerstone for maintaining the good health of breast and urogenital tract and for primary or secondary osteoporosis prevention in POI. Fertility should be managed through an individualized approach based on patient possibilities, such as egg or embryo donation and ovarian cryopreservation; pregnancy can occur spontaneously in a minority of cases. Women with POI should be carefully monitored for cardiovascular risk factors. PMID:27252868

  10. Bartonella, a common cause of endocarditis: a report on 106 cases and review.

    Bartonella spp. are fastidious bacteria that cause blood culture-negative endocarditis and have been increasingly reported. In this study, we included all patients retrospectively and prospectively diagnosed with Bartonella endocarditis in our French reference center between 2005 and 2013. Our diagnosis was based on the modified Duke criteria and microbiological findings, including serological and PCR results. To review the published literature, we searched all human Bartonella endocarditis cases published in the PubMed database between January 2005 and October 2013. We report here a large series of 106 cases, which include 59 cases that had not previously been reported or mentioned. Indirect immunofluorescence assays, Western blotting, and real-time PCR from total blood, serum, and valve tissue exhibited sensitivities of 58%, 100%, 33%, 36%, and 91%, respectively. The number of cases reported in the literature between 2005 and 2013 increased to reach a cumulative number of 196 cases. The number of cases reported in the literature by other centers is increasing more rapidly than that reported by our French reference center (P < 10(-2)). Currently, there is a lack of criteria for the diagnosis of Bartonella endocarditis. We suggest that a positive PCR result from a cardiac valve or blood specimen, an IgG titer of ≥800 using an immunofluorescence assay, or a positive Western blot assay be considered major Duke criteria for Bartonella endocarditis. There is no real increase in the incidence of these infections but rather a better understanding and interest in the disease resulting from the improvement of diagnostic tools. PMID:25540398

    Odontogenic carcinosarcoma is an extremely rare malignant odontogenic tumor with only a few reported cases. It is characterized by a true mixed tumor showing malignant cytology of both epithelial and mesenchymal components. It has been assumed to arise from pre-existing lesions such as ameloblastoma, ameloblastic fibroma, and ameloblastic fibrosarcoma. To date, the reported cases have exhibited considerably aggressive clinical behavior. The case of an odontogenic carcinosarcoma in the mandible of a 61-year-old male is described herein. The tumor destroyed the cortex of the mandible and invaded the adjacent tissues. Treatment was performed by surgical resection and reconstruction. The purposes of this article are to introduce odontogenic carcinosarcoma through this case study, to distinguish it from related diseases and to discuss features of the tumor in the existing literature.

    Clinicians are often intrigued by the varied manifestations of the gingival tissue. Gingival overgrowth is a common clinical finding and most of them represent a reactive hyperplasia as a direct result of plaque-related inflammatory gingival disease. These types of growth generally respond to good plaque control, removal of the causative irritants, and conservative tissue management. This case series highlights three different cases of localized gingival overgrowth and its management with emphasis on the importance of patient awareness and motivation. PMID:27307683

    Actinic prurigo (AP) is a chronic idiopathic photodermatosis that primarily affects American Indians in the United States and Mestizos in Latin American countries. Clinically, the onset of the disease is usually in the first decade of life but may appear initially in adult life, and it is characterized by symmetric involvement of sun-exposed areas of the skin, particularly areas of the face, resulting in polymorphic erythematous papules, macules, and plaques in different stages of evolution. Lower lip involvement includes swelling, scaling, fissures, hyperpigmentation, and ulcerations of the vermilion border. and in some cases could represent the only manifestation of the disease. The histopathologic features of AP have been studied; however, there is a controversy regarding whether AP cheilitis has distinct histopathologic features that could allow accurate separation from other specific and nonspecific forms of cheilitis. The diagnosis can be challenging, mainly when lip lesions are the only manifestation of the disease. In this study, the authors investigate the clinicopathologic features of 75 cases of AP cheilitis to provide further criteria for its diagnosis and classification. All 75 patients presented with lip lesions. Thirty-three cases were diagnosed as AP cheilitis with cutaneous lesions and 42 cases were diagnosed as AP cheilitis without cutaneous lesions (only lip lesions). Histologically, of the 33 cases with AP cheilitis with cutaneous lesions, 17 (52%) cases showed follicular cheilitis, and of the 42 cases that had only lip lesions, 18 (43%) cases showed follicular cheilitis. Histologically, AP cheilitis can present as follicular cheilitis; thus, supporting the diagnosis. Also, our findings confirm that lip lesions can present as the only manifestation of the disease, showing typical histological and clinical features. This form of cheilitis has not being well described in the dermatologic and dermatopathologic literature. PMID:26981737

    Adenoid cystic carcinoma (ACC) is a malignant tumor of the salivary glands but identical tumors can also arise from the breast. Despite their similar histomorphological appearance the salivary gland- and the breast-derived forms differ in their clinical features: while ACC of the salivary glands (sACC) have an aggressive clinical course, the breast-derived form (bACC) shows a very favourable clinical outcome. To date no exact molecular alterations have yet been identified which would explain the diverse clinical features of the ACCs of different origin. In our pilot experiment we investigated the post-transcriptional features of ACC cases by performing microRNA-profiling on 2-2 bACC and sACC tissues and on 1-1 normal breast and salivary gland tissue. By comparing the microRNA-profiles of the investigated samples we identified microRNAs which were expressed differently in bACC and sACC cases according to their normal controls: 7 microRNAs were overexpressed in sACC cases and downexpressed in bACC tumors (let-7b, let-7c, miR-17, miR-20a, miR-24, miR-195, miR-768-3) while 9 microRNAs were downexpressed in sACC cases and overexpressed in bACC tissues (let-7e, miR-23b, miR-27b, miR-193b, miR-320a, miR-320c, miR-768-5p, miR-1280 and miR-1826) relative to their controls. We also identified 8 microRNAs which were only expressed in sACCs and one microRNA (miR-1234) which was only absent in sACC cases. By target predictor online databases potential targets of the these microRNAs were detected to identify genes that may play central role in the diverse clinical outcome of bACC and sACC cases.

    1994-01-01

    Case-based reasoning is an artificial intelligence methodology for the processing of empirical knowledge. Recent case-based reasoning systems also use theoretic knowledge about the domain to constrain the case-based reasoning. The organization of the memory is the key issue in case-based reasoning. The case-based assistant presented here has two structures in memory: cases and concepts. These memory structures permit it to be as skilled in problem-solving tasks, such as diagnosis and treatment planning, as in interpretive tasks, such as clinical research. A prototype applied to clinical work about eating disorders in psychiatry, reasoning from the alimentary questionnaires of these patients, is presented as an example of the system abilities.

    2015-01-01

    Background Glioblastoma multiforme (GBM) typically presents in the supratentorial white matter, commonly within the centrum semiovale as a ring-enhancing lesion with areas of necrosis. An atypical presentation of this lesion, both anatomically as well as radiographically, is significant and must be part of the differential for a neoplasm in this anatomical location. Case Description We present a case of a 62-year-old woman with headaches, increasing somnolence, and cognitive decline for several weeks. Magnetic resonance imaging demonstrated mild left ventricular dilatation with a well-marginated, homogeneous, and nonhemorrhagic lesion located at the ceiling of the third ventricle within the junction of the septum pellucidum and fornix, without exhibiting the typical radiographic features of hemorrhage or necrosis. Final pathology reports confirmed the diagnosis of GBM. Conclusion This case report describes an unusual location for the most common primary brain neoplasm. Moreover, this case identifies the origin of a GBM related to the paracentral ventricular structures infiltrating the body of the fornix and leaves of the septum pellucidum. To our knowledge this report is the first reported case of a GBM found in this anatomical location with an entirely atypical radiographic presentation. PMID:26623232

    Spinning is a popular indoor stationary cycling program that uses group classes as a motivational tool. Exertional rhabdomyolysis (ER) is frequently reported in athletes and military recruits; however, infrequently it has been reported after spinning class. ER is diagnosed by clinical history, physical exam, and laboratory values. Hydration, electrolyte management, and pain control are key components to treatment of this condition. Severe cases can be complicated by acute renal failure, compartment syndrome, arrhythmia, and disseminated intravascular coagulation. We describe three cases of admission due to rhabdomyolysis after spinning. The diagnosis, admission criteria, and medical treatment of ER are presented in the context of a literature review. A retrospective review of three cases with review of the current literature. The medical and laboratory records of three patient cases were reviewed. A search of the PubMed database was used to perform a comprehensive review of exertional rhabdomyolysis. Our institution's IRB reviewed this study. We report three cases of exertional rhabdomyolysis after spinning and describe the diagnostic workup and medical management of these patients. The diagnosis of ER is made by clinical history, physical exam, and laboratory values. The disease spectrum ranges from mild to severe with the potential of serious complications in some patients. We demonstrate three cases of ER in deconditioned individuals who presented to the emergency department for evaluation. Careful medical management and patient monitoring resulted in improved patient symptomatology and eventual return to physical activity. PMID:25665750

    Eccrine poromas arise from the intraepidermal region of the eccrine sweat duct and most often occur as a benign solitary tumor. There are few reports of the occurrence of multiple lesions, defined as poromatosis, which may present in patients who have undergone radiotherapy and/or polychemotherapy. We report the case of a 43-year-old male with a history of mantle cell lymphoma who had undergone 6 cycles of polychemotherapy. He presented to the dermatology clinic for multiple painful lesions on his palms and soles. Several biopsies were performed consistent with eccrine poromas. The patient was successfully treated with a combination of excision, imiquimod cream, and cryosurgery. This case adds to the literature regarding the pathogenesis and treatment options of eccrine poromatosis. Herein, we report a case of eccrine poromatosis that developed after 6 cycles of chemotherapy. PMID:27170941

    Introduction: Fibrolipoma, a subtype of lipoma is painless, well-circumscribed, slow-growing, submucosal benign adipocyte tumour. It is uncommon in the oral cavity and oropharyngeal region, with rare incidence in the retropharynx even rarest in pediatric age group. Case Report: A very unusual case of fibrolipoma is presented in a pediatric patient, who had a huge retropharyngeal fibrolipoma and who presented with breathing difficulty and increasing stridor. It was managed by intro-oral approach excision. Conclusion: Although rare, retropharyngeal benign tumours should be kept in mind during the differential diagnosis of a paediatric stridor case. Early diagnosis is the key for a better outcome and to alleviate the worsening morbidity. PMID:26788493

    PubMed Central

    2014-01-01

    Introduction Sarcomas of the ovary can either be histologically pure or can represent components of a more complex tumor. Ovarian angiosarcomas are rare, and probably arise from carcinosarcomas, teratomas or the rich ovarian vasculature. To date, only two small case series have been published, one with four cases and the other with seven. Case presentation A 41-year-old Saudi woman presented to our gynecological clinic with abnormal vaginal bleeding. The initial clinical diagnosis was left ovarian cyst. The results of the remainder of her abdominopelvic examination were normal. Peri-operatively, the left ovarian mass resembled a hemorrhagic solid tumor. It was sent for frozen sectioning, which revealed it was an undifferentiated neoplasm. The final histopathological examination showed a vascular neoplasm showing vasoformative arborizing channels of variable sizes and shapes lined by atypical endothelial cells with intact capsule. Areas of necrosis were seen, along with fused anastomosing solid vascular area. She was diagnosed as having an angiosarcoma of intermediate grade, International Federation of Gynecology and Obstetrics stage IA. Conclusions Patients with ovarian angiosarcomas most commonly present with abdominal pain, however some patients present with distant metastases, often in the lungs. Spread beyond the ovary is present at the time of diagnosis in most reported cases, with disease progression within less than a year after diagnosis. Cases of advanced stage disease behave aggressively and demonstrate poor response to surgery and chemotherapy, with an overall poor prognosis. They have a tendency for local recurrence and metastases, and prognosis is hence poor; the reported five-year survival rate is 10 percent to 35 percent, however, cases confined to the ovary have survived up to nine years.

    Postanoxic myoclonus is a rare manifestation after an anoxic event, with fewer than 150 cases reported in the literature. The condition is characterized by myoclonic jerks, which are worse on action than at rest, and postural lapses, ataxia, and dysarthria. The disability caused by postanoxic myoclonus can be profound, and treatment in the rehabilitation setting is exceptionally challenging. We present 2 patients who suffered from postanoxic myoclonus after an anoxic event, both of whom were successfully treated with a combination of levetiracetam, valproic acid, and clonazepam. These cases act as a framework for discussing the management of postanoxic myoclonus in the clinical setting. PMID:24060492

    Luxatio erecta, inferior dislocation of the glenohumeral joint, is a rare type of injury (1% of shoulder dislocations). In most cases the injury is caused by falling while the upper extremity is hyperabducted. We introduce two cases of consecutive patients with the same rare type of injury--walking the dog. According to the literature, the most frequently used method for the reduction of inferior shoulder dislocation is tractioncountertraction under sedation. If the patient has no other reason to be under general anesthesia or sedation, we recommend, however, administration of local anesthetics and using a less traumatic two-step manoeuvre to reduce inferior shoulder dislocation--luxatio erecta.

While the findings in these patients overlap with previously described genetic conditions, the similarity in phenotypes among these patients has led to the establishment of a at least one distinct syndrome: HPE, ectrodactyly, and bilateral cleft lip-palate syndrome (OMIM 300571). There has been great interest in identifying a genetic cause for the findings in patients with HPE and ectrodactyly; however the cause(s) of this rare association still remain unknown. PMID:20104609

    The authors have trawled the literature on self-inflicted Caesarean section, assessing circumstances and probable motivation; 19/22 cases had sufficient information. In seven cases, the apparent intention was to kill the child. In four, the action resulted from some form of mental illness. In eight, the woman, in the agony of obstructed labour, took matters into her own hands. We think the third group would be more numerous if there were more publications from Africa and South Asia, where many women give birth without the aid of modern obstetrics. The survival rate among the mothers was surprisingly high. PMID:24318749

    Introduction: Meningiomas are slow-growing benign tumors that arise at any location where arachnoid cells reside. Although meningiomas account for a sizable proportion of all primary intracranial neoplasms (14.3–19%), only 1.8 to 3.2% arise at the foramen magnum. Their indolent development at the craniocervical junction makes clinical diagnosis complex and often leads to a long interval between onset of symptoms and diagnosis. Case report: We report a case of a 79-year-old male patient, presented with ataxia and sense of threatening fainting during verticalization. Magnetic resonance imaging revealed the presence of meningioma in the right side of craniospinal junction. PMID:27041817

    Neuroblastoma is the most common malignancy in children less than one year of age, but is rare in adults. Adult neuroblastoma differs from pediatric cases by lacking classical features including low incidence of MYCN amplification, elevated urinary catecholamimes, and MIBG avidity. The diagnosis may not be initially considered because of the rarity, which emphasizes the importance of immunohistochemical staining and cytogenetic testing in aiding the diagnosis. We present a case of neuroblastoma in a 39-year-old woman who failed to respond to intensive therapy for this malignancy and died within a year after diagnosis. PMID:23462610

    Otocephaly complex is a rare and usually lethal syndrome characterized by a set of malformations consisting of microstomia, mandibular hypoplasia/agnathia, and ventromedial malposition of the ears. Those cases that have been diagnosed prenatally have used an ex utero intrapartum treatment procedure to establish a definitive airway. However, prenatal diagnosis continues to be challenging, primarily because of poor diagnostic sensitivity associated with ultrasonography. We present a case of a newborn with an unanticipated otocephaly complex requiring emergent airway management. In this report, we discuss the medical and ethical issues related to the care of a newborn with this frequently fatal condition. PMID:27258179

    Equestrian perniosis is a rare form of perniosis that is predominantly seen in young female equestrians who ride in cold temperatures. Tight fitting clothing, age under 35 years, and smoking can contribute to the disease manifestation. The diagnosis can be determined from a thorough history and physical examination. However, a biopsy can be taken to confirm the diagnosis. Although many cases are self-limiting and resolve within a few days to weeks of diagnosis, nifedipinie can be considered as a therapeutic measure for persistent cases. Measures such as wearing loose fitting clothing and horseback riding in warmer temperatures and for shorter time periods can prevent recurrence. PMID:26632804

    Leiomyosarcoma (LMS) of the larynx is a very rare malignancy that originates from blood vessel, smooth muscle or from the heterotopic mesenchymal tissue in the larynx. The histological diagnosis of LMS depends on the immunohistochemical investigation. The case is here presented of an 82-year-old man with shortness of breath and hoarseness. Indirect laryngoscopy showed a pedunculated large glottic lesion causing airway obstruction. Direct laryngoscopy was performed and biopsies were taken. From the pathological examination, the diagnosis of LMS was made. This case is presented of laryngeal LMS with the clinical, radiological, and histological findings. PMID:26981488

    Many dentists have patients in their practice with mandibular exostoses, termed torus mandibularis. The majority of these asymptomatic, benign bony outgrowths remain undisturbed over the patient's lifetime. However, the tori occasionally need to be removed. The differential diagnosis for the tori are discussed as well as the indications and techniques for their removal. Various hypotheses concerning the etiology and epidemiology of torus mandibularis are also reviewed. PMID:8536198

    Shotguns are usually used to fire multiple pellets; however, they are capable of firing a single projectile in the form of a slug. Although rare, shotgun slug injuries are severe, producing wounds comparable to those inflicted by high-velocity weapons with the potential for even more tissue destruction because of the slug's size and mass. We report the first survivor of a close range shotgun slug injury, with a review of this weapon's unique projectile ballistics and the relevant literature. PMID:8614051

    The presence of teeth at birth or within a month post-delivery is a rare condition. A newborn, a 2 days old female, with two mandibular incisor natal teeth was examined. The teeth were mobile and were extracted because of the fear of aspiration and refusal to feed. The purpose of this report is to review the literature related to natal teeth epidemiology and discuss their possible etiology and treatment. PMID:21886998

    Disseminated histoplasmosis is an AIDS-defining illness that can affect multiple organ systems. Myositis due to histoplasmosis is rare in HIV infected patients. We report here an HIV-infected patient who presented with myositis caused by Histoplasma capsulatum. Her HIV was under poor control and her CD4 cell count was only 11 cells/mm3. She responded well to treatment but later succumbed to another opportunistic infection. The literature on disseminated histoplasmosis is reviewed. PMID:26867394

    Spontaneous coronary artery dissection (SCAD) is a rare and often lethal cause of acute coronary syndrome, which typically affects young women and otherwise healthy individuals. SCAD can be diagnosed in patients undergoing coronary angiography and can be underestimated. Special techniques such as optical coherence tomography (OCT) and intravascular ultrasound should be used when there is suspicion of the condition. In the majority of cases, the left anterior descending (LAD) artery is involved; however, a few cases of the right coronary artery (RCA) involvement have been reported. This article describes three cases of SCAD in women of different ages, all presenting with chest pain. Coronary angiography in conjunction with OCT was used for diagnosis in two of the cases. One of the patients had involvement of the proximal RCA and underwent percutaneous coronary intervention, whereas the other two patients had mid-LAD disease and were treated conservatively with medical therapy. Presently, there are no specific guidelines for the treatment of SCAD, and therapy is individualized according to extent and severity of the condition. PMID:25317273
