    Trisomia 21 pary chromosomów (Zespół Downa, DS) jest jednym z częściej występujących zaburzeń chromosomalnych w praktyce pediatrycznej. Zaburzenia funkcji tarczycy często występują u tych pacjentów. Niedoczynność tarczycy jest rozpoznawana u blisko 50% pacjentów z ZD, a liczba ta wzrasta wraz z wiekiem. Nadczynność tarczycy jest rozpoznawana znaczniej rzadziej u dzieci z ZD. Odpowiednia strategia leczenia nadczynności tarczycy jest bardzo istotna ze względu na możliwość zaburzenia rozwoju dzieci. Przedstawiamy dwa przypadki dzieci z zespołem Downa i nadczynnością tarczycy. Proces leczenia tych pacjentów był odmienny.

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    Protothecosis is a rare infection caused by achlorophyllic algae called Prototheca. Approximately 117 cases have been described in the literature world wide, the majority caused by the species P. wickerhamii. Cutaneous infection is the most common and cases of tenosynovitis are very rare. A local or systemic immunosuppressive factor is seen in half of the cases of protothecosis. We report a case of protothecal tenosynovitis in a middle-aged, immunocompetent woman that developed after she received sclerosing therapy of varicose veins. Administration of itraconazole with surgical débridement produced a good response. We also review the published cases of protothecal tenosynovitis. PMID:18791778

  20. Case studies in working memory: a case for single cases?

    PubMed

    Della Sala, S; Logie, R H; Marchetti, C; Wynn, V

    1991-06-01

    Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects. The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits. The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.

    The short case is a highly artificial scenario, in which the examination candidate is given little or no history and instructed to examine one system or one aspect of a patient and draw conclusions. Despite their artificiality, short cases test clinical skills which senior paediatricians value and consider essential qualities of a competent physician. This article presents some general suggestions on an approach to doing short case examinations.

    We introduce hierarchical safety cases (or hicases) as a technique to overcome some of the difficulties that arise creating and maintaining industrial-size safety cases. Our approach extends the existing Goal Structuring Notation with abstraction structures, which allow the safety case to be viewed at different levels of detail. We motivate hicases and give a mathematical account of them as well as an intuition, relating them to other related concepts. We give a second definition which corresponds closely to our implementation of hicases in the AdvoCATE Assurance Case Editor and prove the correspondence between the two. Finally, we suggest areas of future enhancement, both theoretically and practically.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    OBJECTIVE: Neck abscess is a disease that might cause mortality and severe morbidity, if it is not treated urgently. In our study, patients with diagnosis of neck abscess in our clinic were analyzed retrospectively and presented in the light of the literature. METHODS: In our clinic, age distribution, source of infection, systemic disease, imaging methods that were used in diagnosis, preferred anaesthesia during drainage, abscess sites, culture results of abscess material, complications during treatment procedure, any antibiotherapy before admission and duration of hospitalization of 79 cases with neck abscess who were treated in the hospital between January 2008 and January 2015 were assessed. RESULTS: Cases in our study were aged between 1–79 (mean 28.3) years and 43 of them were female and 36 were male patients. Systemic diseases were determined in 19 of the cases. The most common systemic disease was diabetes mellitus. Abscesses were localized mostly at peritonsillar region and 13 of the cases were operated when abscess were in multipl localizations. In 74 of the cases, drainage was performed under local anaesthesia and in 5 cases under general anaesthesia. Four of these 5 cases, abscesses were localized within retropharyngeal region and 1 of them had multiple abscesses at various regions. Staphylococcus aereus was the most detected microorganism based on culture results. Three adult cases were followed up in the intensive care unit because of development of mediastinitis. One of these 3 cases exited because of sepsis. Hospitalization periods of 79 cases ranged between 2–21 days (mean 7.64 days). Hospitalization period of 19 cases with systemic diseases were 9.47 days (p<0.05) and statistically which were statistically significantly longer when compared with those without any systemic disease. CONCLUSION: Neck abscess must be diagnosed early and treated with surgical drainage and parenteral therapy because it might cause severe complications. PMID:28058371

  10. [Autoptically confirmed malpractice cases].

    PubMed

    Madea, Burkhard

    2008-01-01

    Claims of lethal medical malpractice cases in penal law are mostly dealt with by experts in forensic medicine since in lethal cases the autopsy is crucial for determining the cause of death. Knowledge of the cause of death, in turn, is the necessary basis of an expert opinion on negligence and the causality between negligence and cause of death. Compared to civil lawsuits filed for malpractice and cases dealt with at the arbitration committees of the medical councils penal lawsuits with 1500 to 2000 cases per year are of minor importance. Our own retrospective multicentre study on lawsuits filed for lethal cases of medical malpractice (based on autopsy findings of 4450 cases) revealed an annual increase in autopsies due to medical negligence from 3 to 6 hundred. Hospital doctors are more frequently affected by medical malpractice claims than private-practice physicians. However, the rate of confirmed medical malpractice cases is much higher for doctors in private practice. Although surgeons are most frequently charged with medical malpractice the rate of confirmed medical malpractice cases is comparatively low in surgery. Medico-legal autopsies in cases of alleged medical malpractice are often ordered by the public prosecutor because the manner of death was classified as unnatural or undetermined. Therefore the often-heard reproach that doctors frequently make mistakes and do their very best to hide them is not true. Thus, it has to be recommended that in a case of unexpected death associated with medical treatment the doctor in his own interest should classify the manner of death as undetermined.

    CASE (Computer-Aided Software Engineering) is a set of methodologies for software design, development, and maintenance supported by a complex of interconnected automation tools. CASE is a set of tools for the programmer, analyst, and developer for the automation of software design and development. Today, CASE has become an independent discipline in software engineering that has given rise to a powerful CASE industry made up of hundreds of firms and companies of various kinds. They include companies that develop tools for software analysis and design and have a wide network of distributors and dealers, firms that develop specialized tools for narrow subject areas or for individual stages of the software life cycle, firms that organize seminars and courses for specialists, consulting firms, which demonstrate the practical power of CASE toolkits for specific applications, and companies specializing in the publication of periodicals and bulletins on CASE. The principal purchasers of CASE toolkits abroad are military organizations, data-processing centers, and commercial software developers.

    The emphysematous pyelonephritis is a rare and severe renal infection characterized by the presence of gas in renal parenchyma and its perirenal spaces. We report two cases of emphysematous pyelonephritis in two diabetic women (53 and 50 years old respectively). In the first case, the treatment was based on nephrectomy because of the presence of a septic shock and three risk factors, which are acute renal failure, hematuria and thrombopenia. In the second case, the treatment was only medical. The evolution was favorable in the two cases. We insist in this article that this diagnosis should be considered in every female diabetic patient having severe acute pyelonephritis resistant to a well-conducted medical treatment.

  1. Case Management Directors

    PubMed Central

    Bankston-White, Cheri; Birmingham, Jackie

    2015-01-01

    Purpose and Objectives: Case management directors are in a dynamic position to affect the transition of care for patients across the continuum, work with all levels of providers, and support the financial well-being of a hospital. Most importantly, they can drive good patient outcomes. Although the position is critical on many different levels, there is little to help guide a new director in attending to all the “moving parts” of such a complex role. The purpose of this two-part article is to provide case management directors, particularly new ones, with a framework for understanding and fulfilling their role. We have divided the guide into seven tracks of responsibility. Part 1 discusses the first four tracks: (1) staffing and human resources, (2) compliance and accreditation, (3) discharge planning, and (4) utilization review and revenue cycle. Part 2 addresses (5) internal departmental relationships (organizational), (6) external relationships (Community agency), and (7) quality and program outcomes. Primary Practice Setting: The information is most meaningful to those case management directors who work in either stand-alone hospitals or integrated health systems, and have frontline case managers reporting to them. Findings/Conclusions: Case management directors would benefit from further research and documentation of “best practices” related to their role, particularly in the areas of leadership and management. New directors would benefit from mentoring and networking with one another. Implications for Case Management: As new regulations and models of care bring increased emphasis and focus to transitions of care, the role of the case management director continues to evolve, growing in importance and complexity. The growing financial impact of readmissions also brings added scrutiny and increased pressure to get the transitions of care right the first time. To operate most effectively, case management directors must understand the full range of their

    Epidermolytic hipercetarose is a rare genodermatosis, with a prevalence of 1:100.000 to 1:300.000, with autosomal dominant inheritance. We report the case of a 5 year old girlwho presented an hypertrophic verrucous plaques in the neck, under arm, buttocks, knees, pelvis, legs, dorsum of the right foot and elbows. Histological examination of the skin lesions showed typical changes of epidermolytic hyperkeratosis. Because it is an autosomal dominant disorder with complete penetrance, the individual carrying the mutation will necessarily develop the disease. However, in 50% of cases postzygotic mutation occur. The case report emphasizes early diagnosis and differential diagnoses with ichthyosis and other bullous diseases of childhood, as well as discussing the therapeutic possibilities. PMID:26734873

    NASA Technical Reports Server (NTRS)

    Denney, Ewen W.; Naylor, Dwight; Pai, Ganesh

    2014-01-01

    Querying a safety case to show how the various stakeholders' concerns about system safety are addressed has been put forth as one of the benefits of argument-based assurance (in a recent study by the Health Foundation, UK, which reviewed the use of safety cases in safety-critical industries). However, neither the literature nor current practice offer much guidance on querying mechanisms appropriate for, or available within, a safety case paradigm. This paper presents a preliminary approach that uses a formal basis for querying safety cases, specifically Goal Structuring Notation (GSN) argument structures. Our approach semantically enriches GSN arguments with domain-specific metadata that the query language leverages, along with its inherent structure, to produce views. We have implemented the approach in our toolset AdvoCATE, and illustrate it by application to a fragment of the safety argument for an Unmanned Aircraft System (UAS) being developed at NASA Ames. We also discuss the potential practical utility of our query mechanism within the context of the existing framework for UAS safety assurance.

    In paternity test using the DNA evidence, the analysis of the deficient case that the DNA profiles of mother or alleged father are not available is different from that of the trio case analyzed routinely. However, the motherless case that the genotypes of mother is not available has been requested and analyzed like the trio case. In this paper, we compared the motherless case and the trio case through the mean exclusion chance describing the probability of exclusion for a genetic marker system and the distribution of the probability of paternity calculated using the three current methods. We have also shown a case which can be falsely discriminated if it were requested in the analysis of the motherless case, and conclude that the analysis of the motherless case should be carefully conducted and the level for the discrimination should be different from that of the trio case.

    Adnexal torsion is a gynecological emergency caused by the torsion of the ovary over its pedicle producing lymphatic and venous stasis, later it develops into ischemia and necrosis, when is not treated. Until recently, the treatment for adnexal torsion has been adnexectomy. This paper report three cases treated successfully with conservative treatment. It is essential to establish a protocol for adnexal torsion management where radical treatments are abandoned and conservative surgeries, such as detorsion and plication, are performed. We suggest as a first choice management adnexal detorsion, in case malignity is suspected to have intraoperative pathologic analysis, and based on the results to decide to preserve the adnexal or remove it for definitive cure.

    1999-01-01

    A woman with hirsutism but otherwise symptom-free was found to have a raised serum prolactin and a pituitary microadenoma. The hyperprolactinaemia persisted despite bromocriptine therapy and subsequent pituitary surgery, which yielded a non-functioning adenoma. After a further 15 years with persistent hyperprolactinaemia but no symptoms, macroprolactinaemia was diagnosed. Such cases might account for part of the failure rate of pituitary microsurgery for prolactinoma. Testing for macroprolactinaemia is advisable in a woman with hyperprolactinaemia, especially if her ovulatory cycle is normal. Two other cases are reported in which macroprolactinaemia was associated with menstrual disturbances and other hormonal effects: in these, treatment with dopamine agonists suppressed the hyperprolactinaemia and restored normal menstrual cycles.

    Adamantinoma is a primary tumor of long bones, which affects mainly the shaft of the tibia, and is extremely rare in pediatrics. It frequently presents during the second decade of life, with a slight predominance in males. It is a low grade tumor, with local aggressiveness and low rate of metastasis and recurrence once it is completely removed. Its diagnosis is difficult, not only because it is a rare disease in children, but also because of the difficulty in the differential diagnosis with other benign lesions. We report the case of a 15-year-old patient with a painless swelling of the distal tibia, whose diagnosis was confirmed with the piece of amputation, as imaging features and both initial biopsies were not enough to achieve diagnosis. Though most of the literature consists of case reports, and very few in pediatric patients, they all agree on the difficulty in achieving the diagnosis of adamantinoma.

    Abstract Rapunzel syndrome is very rare gastric foreign bodies that occur in children. It is a severe condition of a gastric trichobezoar with a long tail that passes into the small intestine. Here, we present the case of an 8-year-old girl with Rapunzel syndrome due to a very large (7 × 7 × 30 cm) gastric trichobezoar. The patient had trichotillomania and trichophagia for 1 year prior to presentation. Ideally, small bezoars are removed through a minimally invasive method, such as endoscopic fragmentation. However, large trichobezoars, including those in Rapunzel syndrome, can only be managed with open surgical extraction, despite the large scars that may result. We report a case of Rapunzel syndrome with a large bezoar that was surgically removed after it was endoscopically cauterized with argon plasma. Endoscopic precutting was used to effectively reduce the size of the bezoar. PMID:27258502

    We undertake a comparison of observed Algol-type binaries with a library of computed Case A binary evolution tracks. The library consists of 5500 binary tracks with various values of initial primary mass M{sub 10}, mass ratio q{sub 0}, and period P{sub 0}, designed to sample the phase-space of Case A binaries in the range -0.10 {le} log M{sub 10} {le} 1.7. Each binary is evolved using a standard code with the assumption that both total mass and orbital angular momentum are conserved. This code follows the evolution of both stars until the point where contact or reverse mass transfer occurs. The resulting binary tracks show a rich variety of behavior which we sort into several subclasses of Case A and Case B. We present the results of this classification, the final mass ratio and the fraction of time spent in Roche Lobe overflow for each binary system. The conservative assumption under which we created this library is expected to hold for a broad range of binaries, where both components have spectra in the range G0 to B1 and luminosity class III - V. We gather a list of relatively well-determined observed hot Algol-type binaries meeting this criterion, as well as a list of cooler Algol-type binaries where we expect significant dynamo-driven mass loss and angular momentum loss. We fit each observed binary to our library of tracks using a {chi}{sup 2}-minimizing procedure. We find that the hot Algols display overall acceptable {chi}{sup 2}, confirming the conservative assumption, while the cool Algols show much less acceptable {chi}{sup 2} suggesting the need for more free parameters, such as mass and angular momentum loss.

    This report summarizes efforts expended in the development of an all-composite compressor case. Two pre-production units have been built, one utilizing V-CAP and one utilizing AFR-700B resin systems. Both units have been rig tested at elevated temperatures well above design limit loads. This report discusses the manufacturing processes, test results, and Finite Element Analysis performed. The V-CAP unit was funded by NASA-Lewis Research Center in 1994 under contract number NAS3- 27442 for Development of an All-Composite OMC Compressor Case. This contract was followed by an Air Force study in 1996 to build and identical unit using the AFR-700B resin system in place of the V-CAP system. The second compressor case was funded under U.S. Air Force contract F33615-93-D-5326, Advanced Materials for Aerospace Structures Special Studies (AMAS3), Delivery Order 0021 entitled "Advanced Polymeric Composite Materials and Structures Technology for Advanced High Temperature Gas Turbine Engines.' Initial studies using the V-CAP resin system were undertaken in 1993 under a NASA Lewis contract (NAS3-26829). A first prototype unit was developed in a joint program between Textron-Lycoming (now Allied Signal) and Brunswick (now Lincoln Composites). This unit included composite end closures using low density, high temperature molded end closures. The units was similar in size and shape to a titanium case currently used on the PT-21 0 engine and was funded as part of the integrated High Performance Turbine Engine Technology (EHPTET) initiative of DOD and NASA.

    Abstract Background: Cases of macrolide-resistant Mycoplasma pneumoniae have increased rapidly since 2000, especially in Asia. Patients infected with macrolide-resistant M pneumoniae usually present with severe M pneumoniae pneumonia. The aim of this study was to identify indicators for whether children at an early stage of M pneumoniae infection develop mild or severe pneumonia. Case Summary: Herein, we retrospectively reviewed 2 pediatric cases caused by macrolide-resistant M pneumoniae, but with markedly different severity of pneumonia. First, we compared the clinical courses of the patients, then isolated the pathogens and tested their response to macrolides, then finally, carried out whole genome sequencing of these isolates. Despite the difference in clinical presentation of the infection, both isolates exhibited a high level of resistance to macrolide antibiotics. Analysis of clinical data showed that the erythrocyte sedimentation rate in blood samples of the patients in the early stages of disease varied greatly. Genome sequence analysis revealed single nucleotide polymorphisms mainly focused on adhesin P1, which is involved in the pathogenicity of M pneumoniae. Conclusion: The differences of erythrocyte sedimentation rate in the early stage of M pneumoniae pneumonia and mutations in P1 protein may help us to distinguish between severe or mild disease after infection with macrolide-resistant M pneumoniae. These findings could lead to the development of screening assays that will allow us to distinguish severe or mild M pneumoniae pneumonia early. PMID:27661056

    The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

We describe a patient who presented with temporary localized edema (classical Calabar swellings) after travelling to Cameroon and in whom the diagnosis of loiasis was made by ELISA. This is the second reported case of loiasis in Korea. As international travel is becoming more frequent, Loa loa infection should be considered in the differential diagnosis for patients with eosinophilia and Calabar swellings in Korea.

It was first described by Jackson in 1838, but it was Gorham and Stout, in 1955, who defined this disease as a specific entity. It has variable clinical presentation and generally has progressive behavior. Controversy continues regarding the treatment and there is no standard treatment. This pathological condition generally presents a favorable prognosis. Here, a case of Gorham's disease with involvement of the left hip is presented, in a male patient without relevant antecedents.

    Human jaws and teeth display a high degree of morphological individuality as they represent personal, family and population characteristics. A protostylid is a supernumerary or accessory cusp located on the mesial half of the buccal surface on the molars that may seldom pose problems while its presence may not be a cause for alarm in most instances. This case report presents a rare finding of protostylid on the buccal surface of the primary molars in 4 children.

Histologically it is characterized by a proliferation of spindle cells in a myxoid stroma. Myxofibrosarcoma has a high potential for local recurrence and metastasis, mainly when it presents a high or intermediate histological grade. We report the case of an eighty-four year old patient with a difficult diagnosis of a highly aggressive tumor.

    Kwashiorkor is part of the spectrum of protein-energy malnutrition. The condition results from a lack of nutritional protein coupled with carbohydrate excess. Protein malnutrition is much more common in the Third World; however, it is also the most common form of nutritional deficiency among hospitalized patients in the United States. Cutaneous clues to the diagnosis of protein deficiency include the "flag sign," hypochromotrichia, alopecia, "crazy pavement" dermatosis, pallor, and glossitis. Systemic manifestations include peripheral edema, liver disease, neurologic changes, diarrhea, weight loss, and hypoalbuminemia. We report here a case of profound kwashiorkor in a nonhospitalized patient who presented with multiple cutaneous and systemic findings indicative of protein malnutrition.

    After a short historical survey 14 cases of celebrated personalities one woman and 13 men, with the grave handicap of amputation are represented. The causes of the lost limbs, once of the nose, were battle injuries (guns) or accidents. In many cases the protheseology followed the amputation, dependent on the technological level of the day. Often medical providing was bad and terrible. The introduction of anaesthesia changed the amputation technique. During different periods from renaissance to the first half of the twentieth century remarkable fates happened. Heroes as the emperor Friedrich III., the knight Goetz von Berlichingen, well known by the spectacle of Goethe, the scientist Tycho Brahe, the merchant and skipper Peter Stuyvesant, the military men Duke Christian II. of Braunschweig-Lueneburg-Wolfenbuettel, William Bayly, Admiral Lord Nelson and Earl Claus Stauffenberg, the actress Sarah Bernhard, the squadron leader of RAF Douglas R.

    Introduction Aglossia is a rare condition caused by failure of the tongue embryogenesis process (in the fourth to eighth weeks of gestation). The tongue is an organ used in different activities such as sucking, swallowing, chewing, and talking. It is also responsible for shaping palate dental arches (in its absence, they become atrophic). There are few similar cases reported in the literature. Objective To describe a rare case of aglossia and the multidisciplinary professionals working together for 5 years to treat the patient. Resumed Report An 8-year-old girl with aglossia had an assessment comprising: (1) clinical assessment of the stomatognathic system related to resting posture, tonus, and mobility; (2) orthodontic assessment; (3) surface electromyography of the chewing muscles; (4) swallowing videofluoroscopy. Conclusion The authors confirmed the need of multidisciplinary cooperation to improve the patient's quality of life, because agenesia implicates many activities/functions that depend on the tongue to fully work. Multiprofessional cooperation helps the patient learn compensation mechanisms. PMID:26722352

    Intravascular papillary endothelial hyperplasia is a benign vascular lesion caused by proliferation of endothelium. It is reactive to thrombotic or inflammatory stimuli in the vessel wall.We report the case of a 14-yearold male patient with a violet-colored erythematous tumoral lesion of progressive growth in the occipital region. The diagnosis of intravascular papillary endothelial hyperplasia (IPEH) was confirmed by clinical and histopathological findings. Total lesion exeresis was performed with no recurrence up to date. IPEH presents clinical importance due to its clinical and histological resemblance to angiosarcoma. In order to differentiate it from angiosarcoma, distinguishing features of the benign disease should be considered, such as lack of cellular atypia and rare mitotic activity.Prognosis is good.

She noticed coarsening of the skin and gradual protrusion of her lower jaw. She complained of headache, vertigo, frequent passage of urine, increased thirst, weight loss and fatiguability. She was found hypertensive having blood pressure 200/110 mm of Hg. Her appearance was coarse with rough skin. There were enlargement of hands, feet, nose, lower jaw with prognathism and enlargement of other acral parts. Investigations revealed high plasma glucose level, both fasting and 2 hrs. after glucose, high level of growth hormone, failure of suppression of growth hormone during OGTT. Thyroid function tests of the patient were found normal with increased heel pad size and enlarged sella turcica in all diameters. She was diagnosed as a case of acromegaly due to growth hormone hypersecretion.

    We describe cervical pregnancy concept and its rareness. Its frequency is one in 2,550 to 98,000 intrauterine pregnancies. Predisposing factors are related with endometrial damage due to uterine curettages and previous cesarian section. Clinical picture was nonspecific and diagnosis was based in endovaginal ultrasonography. It can cause massive bleeding and put life in risk. During 2007 we attend 829 intrauterine pregnancies at Hospital San José de Querétaro: 11 tubal, and 3 cervical, this represents an extraordinarily high frequency of cervical pregnancy. Here we report three cases of cervical pregnancies treated with total hysterectomy, two as urgency and one elective. We remark early diagnosis importance to perform conservative treatment and maintain reproductive function.

    The iniencephaly involves a variable defect in the occipital bone, resulting in a large foramen magnum, partial or total absence of the cervical and thoracic vertebrae, accompanied by incomplete closure of arcs and/or vertebral bodies, significant shortening of the spinal column and hyperextension of the malformed cervicothoracic spine; the individual's face is deviated upward, the mandibular skin is directly continuous with anterior thorax due to the absence of neck. Its incidence is about 1:1000–1:2000 births, so this is a pretty rare neural tube defect. We present a case of iniencephaly in association with cardiovascular, spinal cord, and intracranial malformations that ended demonstrating the low survival of patients affected with this condition.

    Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

    Pleuropulmonary blastoma is a rare lung tumor of childhood that can occur with cystic or solid lesions, as a radiological finding with or without respiratory symptoms. We report the case of a 2 year old toddler in his first pulmonary obstructive episode with suspected toracic malformation of the left upper lobe in his chest x-ray and tomography. Surgery was performed showing cystic malformation of the left upper lobe. We received the pathology report with diagnosis of type I pleuropulmonary blastoma. He began follow-up with Oncology initiating treatment with cyclophosphamide and vincristine, well tolerated. Currently, there is controversy about the management of congenital lung cysts, tilting the balance towards the surgical procedure because of serious difficulties in differentiating benign pulmonary cysts from pleuropulmonary blastoma without histopathologic review.

Histopathological and immunohistochemical examinations confirmed the diagnosis of primary cutaneous large B-cell lymphoma, leg type. This rare, cutaneous lymphoma affects predominantly elderly females. Clinically, patients present with tumoral lesions on one or both legs (worst prognosis). Diagnosis is based on clinical, histopathological and immunohistochemical findings. The strong expression of BCL2, BCL6, MUM-1 and CD20, and the positivity for Ki67 antigen confirm the diagnosis. R-CHOP chemotherapy regimen (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) is the most widely accepted treatment. PMID:25054764

    An explosively separable casing including a cylindrical afterbody and a circular cover for one end of the afterbody is disclosed. The afterbody has a cylindrical tongue extending longitudinally from one end which is matingly received in a corresponding groove in the cover. The groove is sized to provide a picket between the end of the tongue and the remainder of the groove so that an explosive can be located therein. A seal is also provided between the tongue and the groove for sealing the pocket from the atmosphere. A frangible holding device is utilized to hold the cover to the afterbody. When the explosive is ignited, the increase in pressure in the pocket causes the cover to be accelerated away from the afterbody. Preferably, the inner wall of the afterbody is in the same plane as the inner wall of the tongue to provide a maximum space for storage in the afterbody and the side wall of the cover is thicker than the side wall of the afterbody so as to provide a sufficiently strong surrounding portion for the pocket in which the explosion takes place. The detonator for the explosive is also located on the cover and is carried away with the cover during separation. The seal is preferably located at the longitudinal end of the tongue and has a chevron cross section.

    The aim was to report on a rare case of patellar osteochondroma. A 60-year-old man presented a tumor on his left patella that had developed over a 10-year period, which is a rare occurrence, considering the patient's age and the site at which the tumor appeared. The clinical condition comprised mild pain and the presence of a mass, without limitation of flexion-extension or any neurovascular deficit. The tumor dimensions were 8 cm longitudinally × 6 cm transversally × 3 cm anteroposteriorly. It was hardened and was adhering to the patellar bone plane. On radiographs and tomographic scans, we observed areas of greater density corresponding to bone and other less dense areas that could correspond to slow-growing cartilage, with irregularities on the patellofemoral joint surface. Simple resection of the tumor was performed, and the anatomopathological examination confirmed that it was a patellar osteochondroma. Osteochondroma, or osteocartilaginous exostosis, includes a large proportion of the benign bone tumors. It results from cell alterations that trigger unregulated production of spongy bone. It is basically treated by means of surgical removal of the tumor mass. This is not essential, but is recommended in order to avoid lesions caused by contiguity and the risk of malignant transformation.

    Neonatal lupus has a rare incidence, distinct from systemic lupus erythematosus. This is an acquired autoimmune disease associated with maternal antibodies to proteins Ro / La (SSA /SSB), transferred by the placenta; it represents the prototype of passive transfer of antibodies from mother to child. The disease can affect the skin, heart, and rarely, the hepatobiliary or hematologic systems. Congenital complete heart block is the most severe form of neonatal lupus. In clinical practice it is important to distinguish in utero a complete from an incomplete atrioventricular block (AV) in order to render prompt care. We present the case of a new born female, who was diagnosed with an atrio-ventricular block at 26 weeksí gestation. When the baby was delivered at 38 weeksí gestation, she presented bradycardia (54 xí). On the suspicion of neonatal lupus, we required antinuclear antibodies, anti-Sm, anti-RNP, anti-SS-A and anti-SS-B, which were positive. A bicameral pacemaker was placed uneventfully.

    Excess major nutrients occur in offshore areas ranging from the tropical equatorial Pacific to the polar Antarctic. In spite of the great ecological differences in these environments, the authors believe they share a common trait: iron deficiency. Here they present the case of iron; they point out that all of these areas are far from Fe-rich terrestrial sources and that atmospheric dust loads in these regions are among the lowest in the world. The authors summarize experiments performed in three nutrient-rich areas: The Gulf of Alaska, the Ross Sea, and the equatorial Pacific. In general, populations without added Fe doubled at rates 11-40% of the expected maxima at various temperatures. The additions of nanomole quantities of Fe increased these doubling rates by factors of 2-3. In spite of the lack of Fe, tightly coupled phytoplankton/zooplankton communities seem to inhabit these major nutrient-rich areas. Since Fe is required for the synthesis of chlorophyll and nitrate reductase, little chlorophyll is found and NH{sub 3} is the favored N source. Normal rate values of specific productivity indicate that these populations are healthy, but limited by the insufficient Fe supply. When Fe becomes available either artificially in bottle experiments or in the environment as Fe-rich land masses are approached, diatoms quickly bloom, chlorophyll levels increase, and nutrient stocks are rapidly depleted. These combined results indicate that Fe availability is the primary factor controlling phytoplankton production in nutrient-rich areas of the open sea.

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed.

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

    I investigate the issue of whether the various subclasses of radio-loud galaxies are intrinsically the same but have been classified differently mainly due to their being viewed from different directions. Evidence for the two key elements of this popular version of the "unified scheme (US)," relativistic jets and nuclear tori, is updated. The case for the torus opening angle increasing with the radio luminosity of the active galactic nucleus (AGN) is freshly argued. Radio-loud AGN are particularly suited for testing the US, since their structures and polarization properties on different scales, as well as their overall radio sizes, provide useful statistical indicators of the relative orientations of their various subclasses. I summarize recent attempts to bring under a single conceptual framework the USs developed for radio-moderate [Fanaroff-Riley type I (FRI)] and radio-powerful (FRII) AGN. By focusing on FRII radio sources, I critically examine the recent claims of conflict with the US, based on the statistics of radio-size measurements for large, presumably orientation-independent, samples with essentially complete optical identifications. Possible ways of reconciling these results, and also the ones based on very-long-baseline radio interferometry polarimetric observations, with the US are pointed out. By incorporating a highly plausible temporal evolution of radio source properties into the US, I outline a scenario that allows the median linear size of quasars to approach, or even exceed, that of radio galaxies, as samples with decreasing radio luminosity are observed. Thus, even though a number of issues remain to be fully resolved, the scope of unified models continues to expand.

    Esthesioneuroblastoma (olfactory neuroblastoma) is an uncommon neuroectodermal tumor. Its biological activity ranges from indolent growth to local recurrence and rapid widespread metastasis. Treatment options consist of surgical resection followed by radiation therapy for primary lesions and the addition of chemotherapy for advanced, recurrent, or metastatic lesions. Patients often present with nasal obstruction, rhinorrhea, recurrent epistaxis, hyposmia, or anosmia. We report a case of esthesioneuroblastoma involving bilateral nasal cavity leading to bilateral nasal obstruction, epistaxis and proptosis of the right eye associated with decreased visual acquity on that eye and loss of smell. A diffuse nontender, 6x6 cms swelling with illdefined margins was seen over the nasal bridge, extending superiorly to glabella and laterally to right maxillary region. X-ray PNS showed soft tissue mass in the nasal cavity with destruction of nasal septum, intense periosteal reaction with destruction of right maxillary wall and extension to right orbit. CT scan of paranasal sinuses showed 8.5 x 4.9 x 7.8 cms irregularly marginated heterogeneous iso- to hyper dense soft tissue mass lesion with extensive adjacent bony destruction and spiculated periosteal reaction involving bilateral nasal cavity and anterior cranial fossa. Biopsy from right nasal mass showed neuroblastoma. The patient received radiotherapy and chemotherapy. The modified Kadish staging system, lymph node status, treatment modality, and age are useful predictors of survival in patients who present with esthesioneuroblastoma. Excellent outcomes for esthesioneuroblastoma are achievable. Long-term follow-up is necessary because of the extended interval for recurrent disease; unlike most sinonasal malignancies, surgical salvage is possible.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    2015-11-01

    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.

    2014-10-01

    Radiologists come across interesting patient cases almost every day. This work proposes a novel case database server for quick and easy storage of such cases including whole image series, patient data, and annotations. Cases can be added to the database by saving DICOM images into a predefined directory on the local network. The application automatically extracts patient and study data from the DICOM header and saves it in the database while images are stored as anonymized JPEG files. Users can mark their cases as private or public (visible to all users). Different data fields for annotations and categorization of a case are available. The user frontend also provides several retrieval mechanisms allowing for browsing the cases and performing different kinds of search queries. The stored series can be scrolled interactively in the form of scrollable image stacks. The project is realized as a web-based application using a portable web and database server software package (XAMPP). This makes the system very lightweight and easy to run on almost any desktop computer, even from a USB flash drive, without the need for deeper IT knowledge and administrative rights.

    Central nervous system (CNS) involvement by rheumatoid arthritis (RA) in the form of rheumatoid meningitis (RM) is rare and most commonly occurs in the setting of longstanding severe RA. Due to a wide range of clinical presentations and nonspecific laboratory findings, it presents a diagnostic challenge often requiring brain biopsy. Only a few histopathologically confirmed cases have been described in the literature. Our aim is to describe two cases of RM and review the literature. The first case is of a previously healthy 37-year-old man who presented with severe headaches and focal neurologic deficits. Magnetic resonance imaging demonstrated abnormal leptomeningeal enhancement in the left frontal and parietal sulci. The second case is of a 62-year-old woman with a history of mild chronic joint pain who presented with confusion, personality changes and seizures. Both patients ultimately underwent brain biopsy which demonstrated RM on pathologic examination. Administration of corticosteroids resulted in significant clinical improvement in both cases. To our knowledge, our unusual case of RM in the young man is the fifth reported case of rheumatoid meningitis in a patient with no prior history of RA. Such an atypical presentation makes diagnosis even more difficult and highlights the need for awareness of this entity in the diagnostic consideration of a patient presenting with unexplained neurologic symptoms. Our literature review underscores the clinical and pathologic heterogeneity of CNS involvement in RA.

  20. Electromagnetic fields in cased borehole

    2001-07-20

    Borehole electromagnetic (EM) measurements, using fiberglass-cased boreholes, have proven useful in oil field reservoir characterization and process monitoring (Wilt et al., 1995). It has been presumed that these measurements would be impossible in steel-cased wells due to the very large EM attenuation and phase shifts. Recent laboratory and field studies have indicated that detection of EM signals through steel casing should be possible at low frequencies, and that these data provide a reasonable conductivity image at a useful scale. Thus, we see an increased application of this technique to mature oilfields, and an immediate extension to geothermal industry as well. Along with the field experiments numerical model studies have been carried out for analyzing the effect of steel casing to the EM fields. The model used to be an infinitely long uniform casing embedded in a homogeneous whole space. Nevertheless, the results indicated that the formation signal could be accurately recovered if the casing characteristics were independently known (Becker et al., 1998; Lee el al., 1998). Real steel-cased wells are much more complex than the simple laboratory models used in work to date. The purpose of this study is to develop efficient numerical methods for analyzing EM fields in realistic settings, and to evaluate the potential application of EM technologies to cross-borehole and single-hole environment for reservoir characterization and monitoring.

  1. Understanding and Evaluating Assurance Cases

    NASA Technical Reports Server (NTRS)

    Rushby, John; Xu, Xidong; Rangarajan, Murali; Weaver, Thomas L.

    2015-01-01

    Assurance cases are a method for providing assurance for a system by giving an argument to justify a claim about the system, based on evidence about its design, development, and tested behavior. In comparison with assurance based on guidelines or standards (which essentially specify only the evidence to be produced), the chief novelty in assurance cases is provision of an explicit argument. In principle, this can allow assurance cases to be more finely tuned to the specific circumstances of the system, and more agile than guidelines in adapting to new techniques and applications. The first part of this report (Sections 1-4) provides an introduction to assurance cases. Although this material should be accessible to all those with an interest in these topics, the examples focus on software for airborne systems, traditionally assured using the DO-178C guidelines and its predecessors. A brief survey of some existing assurance cases is provided in Section 5. The second part (Section 6) considers the criteria, methods, and tools that may be used to evaluate whether an assurance case provides sufficient confidence that a particular system or service is fit for its intended use. An assurance case cannot provide unequivocal "proof" for its claim, so much of the discussion focuses on the interpretation of such less-than-definitive arguments, and on methods to counteract confirmation bias and other fallibilities in human reasoning.

    Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

  3. Lunar drill footplate and casing

    1989-01-01

    To prevent hole collapse during lunar drilling operations, a casing has been devised of a graphite reinforced polyimide composite which will be able to withstand the lunar environment. Additionally, this casing will be inserted into the ground in segments two meters long which will penetrate the regolith simultaneously with the auger. The vertical action of the mobile platform will provide a downward force to the casing string through a special adaptor, giving the casing the needed impetus to sink the anticipated depth of ten meters. Casing segments will be connected with a simple snap arrangement. Excess casing will be cut off by a cylindrical cutting tool which will also transport the excess casing away from the hole. A footplate will be incorporated to grasp the auger rod string during rod segment additions or removals. The footplate grasping mechanism will consist of a set of vice-like arms, one end of each bearing threaded to a common power screw. The power screw will be threaded such that one end's thread pitch opposes that of the other end. The weight of the auger and rod string will be transmitted through the arms to the power screw and absorbed by a set of three ball bearing assemblies. The power screw will be driven by a one-half horsepower brushless motor actuated by radio control. The footplate will rest on four short legs and be anchored with pins that are an integral part of each leg.

    Sialoliths are a common cause of salivary gland obstruction, usually affecting the submandibular gland. Although many theories are postulated for their formation (dehydration, medications that reduce salivary flow, increased salivary viscosity), no one aspect is clearly the primary etiology. This case report details an unusual case in which a facial hair of the patient apparently became entrapped in Wharton's duct, causing a nidus for the formation of a sialolith.

    Suprasellar germinomas are frequent in childhood and adolescence, particularly in male sex. The clinical and neuroendocrine abnormalities depend of tumor localization: Increased intracranial pressure, visual disturbances, hypopituitarism, Parinaud syndrome. We report two cases of suprasellar germinoma in young male patients (16 and 18 years old). The first patient hrad corticotorpin insufficiency and clinical signs of hypothyroïdism and hypogonadism. The second had central hypocorticism, hypothyroïdism and hypogonadism associated with central diabetes insipidus and hyperprolactinemia. The diagnosis of germinoma was confirmed after surgery by anatomopathologic examination in the first case and by stereotaxic biopsy in the second case. Treatment by radiotherapy improves prognosis of this disease.

    Summary Hypothyroidism is a wide clinical spectrum disorder and only a few cases in literature show this. Rhabdomyolysis and acute renal impairment can be seen concurrently in a hypothyroid state. We report a case of severe hypothyroidism with poor drug compliance leading to rhabdomyolysis and acute kidney injury. Learning points: Hypothyroidism is a rare cause of acute kidney injury. In this case report, we studied a rare occurrence of acute renal impairment due to hypothyroidism with poor drug compliance, which induced rhabdomyolysis. Our report emphasized that thyroid status should be evaluated in patients with unexplained acute renal impairment or presenting with the symptoms of muscle involvement. PMID:27855234

    Background: More than 80% of cases of mesothelioma worldwide have a history of asbestos exposure. In Mongolia, workers in coal burning thermal power plants (TPP) have widely utilized asbestos as an insulation material. Methods: We describe the case of a 47-year-old woman diagnosed with a malignant pleural mesothelioma. She worked in a TPP in Ulaanbaatar, Mongolia for 28 years. Results: A computer tomography (CT) scan showed a circumferential ring around her left lung, and tissues’ samples had a biphasic variant of mesothelioma with epithelioid and sarcomatoid components. Discussion: This is the first reported case of mesothelioma in Mongolia. We expect additional cases of mesothelioma, as well as other asbestos related diseases, will be identified in the future. In order to properly track asbestos related diseases in the country, we recommend the creation of an asbestos related disease registry. PMID:25582747

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    Congenital megacalycosis is a rare renal disorder consisting of caliceal dilatation without evidence of renal pelvic or ureteral obstruction. Since its first description in 1963, only a few cases have been reported. The defect is mostly unilateral, shows male predominance and does not disrupt the renal functions. We report on two male patients with bilateral megacalycosis and different clinical presentations. The first case was diagnosed in adolescence during examination for a urinary tract infection and was followed-up uneventfully for nearly ten years. The second case was found to have megacalycosis during the assessment of antenatal hydronephrosis. We aimed to emphasize the importance of considering megacalycosis in the differential diagnosis of both antenatal hydronephrosis and other causes of caliceal dilatation to prevent unnecessary diagnostic and therapeutic interventions.

    Histoplasma capsulatum var capsulatum is a dimorphic fungus endemic to the Ohio and Mississippi River Valleys of the United States. In this case report, a 33-year-old woman who presented with a right orbital mass causing progressive vision loss, diplopia, and facial swelling is described. Lateral orbitotomy with lateral orbital wall bone flap was performed for excisional biopsy of the lesion. The 1.5 × 1.8 × 2.3 cm cicatricial mass demonstrated a granulomatous lesion with necrosis and positive staining consistent with Histoplasma capsulatum var capsulatum infection. To the authors' knowledge, this is the first case of orbital histoplasmosis to be reported in the United States and the first case worldwide of orbital histoplasmosis due to Histoplasma capsulatum var capsulatum.

    Background. Polyorchidism, alternatively supernumerary testes (SNT), is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery's body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

  3. Approximation of Engine Casing Temperature Constraints for Casing Mounted Electronics

    NASA Technical Reports Server (NTRS)

    Kratz, Jonathan; Culley, Dennis; Chapman, Jeffryes

    2016-01-01

    The performance of propulsion engine systems is sensitive to weight and volume considerations. This can severely constrain the configuration and complexity of the control system hardware. Distributed Engine Control technology is a response to these concerns by providing more flexibility in designing the control system, and by extension, more functionality leading to higher performing engine systems. Consequently, there can be a weight benefit to mounting modular electronic hardware on the engine core casing in a high temperature environment. This paper attempts to quantify the in-flight temperature constraints for engine casing mounted electronics. In addition, an attempt is made at studying heat soak back effects. The Commercial Modular Aero Propulsion System Simulation 40k (C-MAPSS40k) software is leveraged with real flight data as the inputs to the simulation. A two-dimensional (2-D) heat transfer model is integrated with the engine simulation to approximate the temperature along the length of the engine casing. This modification to the existing C-MAPSS40k software will provide tools and methodologies to develop a better understanding of the requirements for the embedded electronics hardware in future engine systems. Results of the simulations are presented and their implications on temperature constraints for engine casing mounted electronics is discussed.

    Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate. The aim of our study was to describe the clinical, biochemical, radiological and therapeutic features of seven patients with systemic sarcoidosis and liver involvement. A retrospective and descriptive monocentric study, over 3 years, including seven patients with systemic sarcoidosis and liver involvement. We included 5 women and 2 men with an average age of 43 years. Hepatic localization revealed sarcoidosis in 5 cases. Hepatomegaly was observed in all patients as well as abnormal serum liver function test reflected by anicteric cholestasis. Liver biopsy, showed in all granulomatous lesions consistent with sarcoidosis and severe fibrosis in 2 cases. Extra-hepatic manifestations were present in all patients represented mainly by pulmonary location. All patients were treated, five by corticosteroid and two with ursodeoxycholic acid (UDCA). Complete response was observed in one case, partial response in another case and corticosteroid refractoriness in one case. In two cases, corticosteroid therapy was introduced for less than 1 month, not allowing assessment of response. Antimalarials in combination with UDCA were used successfully in a patient with steroid-resistant liver disease. Liver involvement can reveal systemic sarcoidois. Given the risk of progression to severe liver disease, it must be screened in all patients with systemic sarcoidosis. Treatment is not systematic, and still based on corticosteroid therapy. In the absence of prospective randomized controlled trials, the efficacy of UDCA need to be proven. PMID:27795804

    Multiple injuries resulting from the use of nail guns have been described in the literature; however, to date there has been no report of a nail gun injury to the abdomen. We describe the case of a 30-year-old male tradesperson who suffered a penetrating nail gun injury to the epigastrium, resulting in multiple injuries to the bowel and an inferior vena caval injury with massive haemorrhage. This case demonstrates the wide range of injuries capable of being inflicted by a single penetrating injury, and emphasizes the need for proper training and safety measures in the use of nail guns.

    Background Colorectal polyps of mesenchymal origin represent a small percentage of gastrointestinal (GI) lesions. Nevertheless, they are encountered with increasing frequency since the widespread adoption of colonoscopy screening. Case presentation We report a case of a small colonic polyp that presented as intramucosal diffuse spindle cell proliferation with a benign cytological appearance, strong and diffuse immunoreactivity for S-100 protein, and pure Schwann cell phenotype. Careful morphological, immunohistochemical and clinical evaluation emphasize the differences from other stromal colonic lesions and distinguish it from schwannoma, a circumscribed benign nerve sheath tumor that rarely arises in the GI tract. Conclusion As recently proposed, this lesion was finally described as mucosal Schwann cell hamartoma. PMID:21663626

    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

    The differential diagnosis of hyponatraemia is manifold and includes hormonal disorders such as primary adrenal insufficiency or hypothyroidism. The diagnosis of adrenal insufficiency is always suggestive in cases of hypotension associated with hyponatraemia, hyperkalaemia and metabolic acidosis. We herein report a case of severe hyponatraemia in a patient with Addison's disease. The underlying cause was disseminated adrenal tuberculosis without any evidence of other organ involvement. To date, tuberculosis remains a frequent cause of adrenal insufficiency although the pathophysiology of adrenal tropism is poorly understood.

    Background. Ascorbic acid (vitamin C) is necessary for the formation of collagen, reducing free radicals, and aiding in iron absorption. SCURVY, a disease of dietary ascorbic acid deficiency, is uncommon today. It still exists in high risk groups including economically disadvantaged populations with poor nutrition. The incidence of SCURVY in the pediatric population is very low. Cases Report. Here we report two cases of SCURVY revealed by subperiosteal hematoma in children with cerebral palsy and developmental delay. Conclusion. SCURVY is extremely rare in children. Musculoskeletal manifestations are prominent in pediatric SCURVY. Multiple subperiosteal hematomas are an important indicator for diagnosis. PMID:20976262

    Arterio-biliary fistula is an uncommon cause of haemobilia. We describe a case of right hepatic artery pseudo-aneurysm causing arterio-biliary fistula and presenting as severe melaena and cholangitis. Gastroduodenoscopy failed to establish the exact source of bleeding and hepatic artery angiography and selective embolization of the pseudo-aneurysm successfully controlled the bleeding. Pseudo-aneurysm of the hepatic artery is mostly iatrogenic due to biliary intervention, as demonstrated in this case. Difficulty in diagnosis and management is discussed together with a review of the literature.

    OBJECTIVE: To describe the characteristics of compatible poliomyelitis cases and to assess the programmatic implications of clusters of such cases in India. METHODS: We described the characteristics of compatible poliomyelitis cases, identified clusters of compatible cases (two or more in the same district or neighbouring districts within two months), and examined their relationship to wild poliovirus cases. FINDINGS: There were 362 compatible cases in 2000. The incidence of compatible cases was higher in districts with laboratory-confirmed poliomyelitis cases than in districts without laboratory-confirmed cases. Of 580 districts, 96 reported one compatible case and 72 reported two or more compatible cases. Among these 168 districts with at least one compatible case, 123 had internal or cross- border clusters of compatible cases. In 27 districts with clusters of compatible cases, no wild poliovirus was isolated either in the same district or in neighbouring districts. Three of these 27 districts presented laboratory-confirmed poliomyelitis cases during 2001. CONCLUSION: Most clusters of compatible cases occurred in districts identified as areas with continuing wild poliovirus transmission and where mopping-up vaccination campaigns were carried out. As certification nears, areas with compatible poliomyelitis cases should be investigated and deficiencies in surveillance should be corrected in order to ensure that certification is justified.

    Abstract Introduction: We report the case of a multicentric Castleman disease (MCD) with initial renal involvement. Although the renal involvement in this case was typical of MCD, it constitutes a rare presentation of the disease, and in our case the renal manifestations led to the haematological diagnosis. Clinical Findings/Patient Concerns: The patient was admitted for fever, diarrhea, anasarca, lymphadenopathies and acute renal failure. Despite intravenous rehydration using saline and albumin, renal function worsened and the patient required dialysis. While diagnostic investigations were performed, right hemiplegia occurred. There was no anemia or thrombocytopenia. Diagnoses: Kidney biopsy was consistent with glomerular thrombotic microangiopathy (TMA). Lymph node histology was consistent with hyalin-vascular variant of Castleman disease. Outcomes: Given the renal and neurological manifestations of this MCD-associated TMA, the patient was treated with plasma exchange during one month, and six courses of rituximab, cyclophosphamide and dexamethasone. The evolution was favorable. Conclusion: Although rare, this diagnosis is worth knowing, as specific treatment has to be started as soon as possible and proved to be efficient in our case as well as in other reports in the literature.

    Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions.

  6. Lingual thyroid: a clinical case.

    PubMed

    Quarracino, María; Aguas, Silvia

    2003-01-01

    Lingual thyroid is an abnormal formation appearing as the result of a deficient descent during embryological development of the thyroid gland through the thyroglossal duct to its normal pretracheal location. The lesion consists of a tumor mass of thyroid tissue located at the base of the tongue, in the region of the foramen caecum linguae. The size can vary from a few millimeters to several centimeters in diameter. More than 400 cases of lingual thyroid have been documented in the literature to date. Lingual thyroid has been identified in 10% of the tongues examined in some autopsy series. Its identification is of great significance, since it may constitute the only functional thyroid tissue in the body, and may inadvertently be destroyed as a result of histological biopsy procedures. The present study presents a clinical case of lingual thyroid in a 17-year-old female.

    The desire for self-mutilation in the absence of any discernible psychopathology is relatively rare. Self-mutilation is most commonly a manifestation of an underlying psychopathology such as depression, schizophrenia, personality disorder, transexuality, body dysmorphic disorder and factitious disorder. In this article, a case in which a 29-year-old single Kenyan lady of African origin demanded a surgical operation to modify and reduce the size of her external genitalia is presented. Although female genital mutilation is still widespread in the country, this case is of interest in that the woman did not seek the usual circumcision but sought to specifically reduce the size of her labia minora so that she could feel like a normal woman. The unique challenges in her management are discussed. Possible aetiological factors in patients who demand surgical removal or modification of parts of their bodies without an obvious cause is discussed.

    Congenital undescending testis is a common anomaly of testis, but we had a rare case of ectopic testis. A 15-month-old infant was operated emergently because of left incarcerate inguinal hernia. Intraoperative exploration of hernial sac revealed two ectopic testes with one spermatic cord proximally but in the middle divided to two spermatic cords in a 8 shape. There was an important point about vas deferens as it was single proximal to the chord, but divided into two in the middle of the chord. Vessels showed a similar condition about. We released both testes and brought down both of them into scrotum. This is a rare case of ectopic testis transectopia with partially common vas and vessels.

    Spheroid body myopathy is a rare illness classified in the group of the congenital myopathies as a desmin-related neuromuscular disorder, presenting dominant autosomical origin with the beginning of the symptoms in the adult phase. We report on a seven years old girl with facial paresia, generalized muscular hypotrophy and hypotony, generalized deep areflexia, proximal upper and lower limbs muscular strengh and distal upper limbs grade 3 and distal lower limbs grade 1. Needle electromyography evidenced increased conscription and potentials of motor unit of short duration and low amplitude, characterizing a myopathic standard. The muscle biopsy disclosed mixed standard to myopathy, denervation and inclusion bodies that are consistent to spheroid body myopathy. In this case, the patient presented, in advance, early beginning of the symptoms and there are no similar cases in the family.

    Gastroschisis is an abdominal wall defect through which intestine and rarely other organs eviscerate. It is less frequently associated with anorectal malformations. Abnormal size and shape of the defect is rarely identified in these patients. We report a case of gastroschisis with an unusual abdominal wall defect, imperforate anus and an ectopically placed vestibule. The defect was extended from right side of umbilicus to the perineum. There was evisceration of entire gastrointestinal tract (GIT), liver, gallbladder and urinary bladder. The defect was not manageable with a spring loaded silo and a sterilized blood bag was used to cover the defect. The unusual defect, associated anomalies and evisceration of unusual viscera are the main reasons for reporting the index case. PMID:22953245

    Kartagener's syndrome is a rare, autosomal recessive genetic ciliary disorder comprising the triad of situs inversus, chronic sinusitis, and bronchiectasis. The basic problem lies in the defective movement of cilia, leading to recurrent chest infections, ear/nose/throat symptoms, and infertility. We hereby report three unusual cases of this rare entity – an infertile male with azoospermia in whom Bochdalek's diaphragmatic hernia coexisted, another case of an infertile female, and a third of an infertile male with oligospermia. The need for a high index of suspicion to make an early diagnosis cannot be overemphasized in such patients so that wherever possible, options for timely treatment of infertility may be offered and unnecessary evaluation of symptoms is avoided.

  13. A case of factitious pedophilia.

    Porter, Theresa M; Feldman, Marc D

    2011-09-01

    Factitious disorder involves feigning, exaggerating, or self-inducing physical and/or psychological ailments with the goal of assuming the "sick" or "patient" role. In turn, the sick role entitles the factitious disorder patient to care, nurturance, and protection; it also exempts one from usual responsibilities. In this paper, we present the first reported case of factitious pedophilia. Although it seems counterintuitive, this middle-aged man has falsely claimed or exaggerated sexual desire for minors ostensibly to remain in a state hospital; indeed, he has remained in the same inpatient facility for more than 20 years as a result of his deceptions. At times, his reports have included disconfirmed claims of bizarre accidents and other physical travails. This case enlarges the literature on factitious psychological disorders and shows that some individuals may falsify paraphilic behaviors, although clearly minimization of these behaviors remains more common.

    Pulmonary alveolar microlithiasis is a rare diffuse lung disease characterized by widespread sand-like intra-alveolar calcifications (calcospherites composed of calcium and phosphorus). Around 800 cases have been reported in the literature to date. We report here a case of a 35 years old female with prolonged h/o of exertional dyspnoea and mild cough. Clinical examination was mostly normal. Her Chest X-Ray revealed bilateral multiple nodular opacities (sand storm appearance). CT Scan chest showed diffuse micronodular calcifications with septal thickening, compatible with alveolar microlithiasis. Pulmonary function tests showed moderately restrictive lung disease. Bronchoscopic alveolar lavage revealed calcospherites in the alveloli and bronchi confirming the diagnosis of pulmonary alveolar microlithiasis.

    The urachus, or median umbilical ligament, is a midline tubular structure that extends upward from the anterior dome of the bladder toward, the umbilicus and represents the vestigial remnant of at least two embryonic structures, the cloaca and the allantois. The tubular urachus normally involutes before birth, remaining as a fibrous band, however its persistence can give rise to various clinical problems, not only in infants and children but also in adults. We report two cases of pyourachus at our institute with a review of the clinical presentation, imaging findings and surgical management. Both our patients were young males, with haematuria being the presenting feature in one case which has not been previously described in literature.

    Saint Louis encephalitis is transmitted by Culex mosquitoes. In Argentina sporadic cases are registered. Symptomatic illness is unusual in children. We present a case of meningoencephalitis caused by an uncommon viral infection. The clinical signs and symptoms are unusual for pediatric patients and the bilateral thalamic compromise showed on magnetic resonance has not been described previously. An 8-year-old girl consulted due to fever, behavior disorders and ataxia. Clonus and neck stiffness were detected at physical exam. Cerebrospinal fluid revealed mononuclear leukocytosis; bilateral ischemic compromise was observed in thalamus by magnetic resonance. Saint Louis virus was confirmed by serology: serum and cerebrospinal fluid IgM were positive during the acute phase of the disease and serum IgG was positive four weeks later. Most of the signs and symptoms of the disease were resolved, however mild behavior disorders were observed as acute sequelae up to 45 days after hospital discharge.

    Mercy Medical Center is a 467 bed, not-for-profit teaching hospital affiliated with a multispecialty group practice and health maintenance organization through contractual arrangements. Historically, strategy development was not helping the hospital remain viable while accomplishing its mission. Strategic planning was fragmented, not focused toward concern for balance of the overall product line, total growth of the organization or the best use of resources. The hospital did not involve the affiliated group practice or HMO in its planning. This last case in Chapter One describes the pursuit of synergy through strategy formulation. The case provides a good example of what Kanter describes as a post-entrepreneurial organization, striving for advantage through collaboration and linkage with "PALs."

    Romani, Fabiana; de Menezes Karam, Simone

    2015-01-01

    Progressive ossifying fibrodysplasia is a rare genetic disease that affects one individual in every two million births. Its main consequence is heterotopic ossification, i.e. formation of additional bone in abnormal locations. It is an autosomal dominant disease, usually caused by a new mutation in the ACVR1 receptor gene, which is in the signaling pathway for bone morphogenic protein. This abnormality is not related to gender, ethnicity or consanguinity. The present study reports the case of A.C., a 17-year-old girl. Her clinical investigation began at the age of four years, but she was only diagnosed with FOP at the age of 15 years, after being evaluated by several specialists in different centers. The patient has two siblings, but her family history did not reveal any similar cases. PMID:27047836

    The oldest existing case histories of craniotomy are from the false Hippocratic writings, about 330 BC, and one is reconstructed about the death of Ptolemy VI in 145 BC. Greek surgeons had rational indications for trepanning, when the difficulties of the times are understood. All compound fractures were infected, so death from an extradural abscess was likely. Trepanning was intended to drain the extra dural space. Copyright 1999 Harcourt Publishers Ltd.

    Targetoid Hemosiderotic Hemangioma, also known as Hobnail Hemangioma, is a lesion of vascular origin, probably lymphatic. The most common clinical feature is a solitary violaceous papule surrounded by a pale, thin area and a peripheral ecchymotic ring, simulating a target. Histopathologically, there is a biphasic pattern, with dilated vessels in the superficial dermis and pseudoangiosarcomatous pattern in the deep dermis, and endothelial cells with hobnail morphology. A simple excision is curative. We report a rare case of Targetoid Hemosiderotic Hemangioma. PMID:25387500

    Alaei, Mohammad Reza; Akbaroghli, Susan; Keramatipour, Mohammad; Alaei, Ali

    2016-01-01

    Introduction Congenital hyperinsulinism is a rare inherited disease caused by mutations in genes responsible for β-cell’s function in glucose hemostasis leading to profound and recurrent hypoglycemia. The incidence of the disease is about 1 in 50000 newborns. Mutations in at least 8 genes have been reported to cause congenital hyperinsulinism. Mutations in ABCC8 gene are the most common cause of the disease that account for approximately 40% of cases. Less frequently KCNJ11 gene mutations are responsible for the disease. Mutations in other genes such as HADH account for smaller fractions of cases. In nearly half of the cases the cause remains unknown. Case Presentation During the period between 2005 and 2010, a total of six patients with persistent hyperinsulinism were investigated at Mofid Children’s Hospital. In this study all of the patients had early onset hyperinsulinemia. Five patients had consanguineous parents. After failure of medical treatment in three patients, They were undergone pancreatectomy. Two diffuse types and one focal type had been recognized in pathological analysis of intra-operative frozen specimens of pancreas in these patients. Genetic analysis was performed using polymerase chain reaction followed by Sanger sequencing for ABCC8, KCNJ11and HADH genes. In five patients homozygous mutations in these genes were identified that indicated an autosomal recessive pattern of inheritance. In one patient a heterozygous mutation in ABCC8 was identified, indicating possible autosomal dominant inheritance of the disease. Conclusions Congenital hyperinsulinism can have different inheritance pattern. Autosomal recessive inheritance is more common but less frequently autosomal dominant inheritance can be seen. It appears that mutations in ABCC8 gene can show both autosomal recessive and autosomal dominant inheritance of the disease. PCR followed by Sanger sequencing proved to be an efficient method for mutation detection in three investigated genes

    Mesiodens is the commonly occurring supernumerary tooth seen between the maxillary central incisors which causes compromised aesthetics and malocclusion. Till date orthodontic therapy provides an excellent solution for the management of mesiodens. Recently, Restorative Space Management (RSM) has been used successfully to correct tooth shape, proportions and colour with minimal tooth preparations. This case report describes the successful management of an unaesthetic smile due to presence of a mesiodens in the midline primarily using aesthetic treatment only. PMID:25298657

    We report two cases of cutaneous cryptococcosis in male patients without underlying disease. Case 1 had a granulomatous mass on his right neck, gradually enlarging for 3 months. After the mass was debrided surgically in a hospital, the incision wound gradually developed into a severe ulceration. Mycological examination revealed Cryptococcus neoformans infection. It was significant that histopathology of both pre-surgery granuloma and post-surgery ulceration revealed thick-walled spores with thick capsule. Chest X-ray revealed a shadow in the left lower lung. After treatment with amphotec for 21 days, the lesion healed. Case 2 had an approximately 2 x 2 cm solitary dull nodule on his right thigh, which had been present for 8 months. Mycological examination confirmed that the lesion was caused by C. neoformans. The patient's ratio of peripheral blood CD4(+) cell was slightly reduced. After 14 days of treatment with oral fluconazole, followed by oral itraconazole for 2 months, mycological and clinical cure were achieved. The two isolates were identified as C. neoformans var. gattii serotype C and C. neoformans var. grubii serotype A.

    Eosinophic fasciitis (EF) is an uncommon connective tissue disease characterized by scleroderma-like cutaneous changes, peripheral eosinophilia, hypergammaglobulinemia, and an elevated erythrocyte sedimentation rate (ESR). Typical histopathologic findings include chronic inflammatory infiltration affecting the deep fascia with lymphocytes, histiocytes, and occasionally eosinophils. We report two cases of EF, the first of which is a 36-year-old man with a tender brownish induration on both forearms, for 2 months. Histopathologic examination showed fibrotic fascia with a mixed inflammatory cell infiltration. The second case is a 52-year-old woman with a symmetrical painful swelling and skin induration on both forearms, for 4 months. A deep biopsy demonstrated chronic inflammatory cell infiltration and hyaline degeneration in the fascia. Increased signal intensity in the fascia and tendon sheath was shown on magnetic resonance imaging. In laboratory examination, mild eosinophilia was found in both cases. Both patients had a history of physical activity (weight training and excessive housework, respectively) and showed marked improvement with high doses of oral prednisolone for several months.

    In the past, it was almost impossible for forensic scientists to separate DNA from an undefined number of different individuals in mixed stains where, for example, two or more suspects had handled the same weapon. Such samples often contain complex mixtures with the consequence of ambiguous or inconclusive mixed DNA profiles. Using the method described of comprehensive and/or targeted screening of shed cells adhering to tapings of garments or objects enables such stains to be individualized. To evaluate the method, 500 microscopically selected single skin flakes were analyzed using two different commercial STR kits to compare the success rates for each PCR typing system. The method has been validated for use in routine casework and has been shown to be rapid, sensitive, and reproducible. It can be predicted that many cases in the archives with body tapings, which have not yet been examined will benefit from this new or perhaps more appropriate, reanimated, technical development, and of particular importance are serious crimes, the so-called cold cases. The remarkable forensic value of this simple but time-consuming technique is exemplified by 2 out of approximately 100 cases already successfully solved using this approach.

    Case 1: A lower abdominal large painful mass was recognized by palpation, CT scan and ultrasonography in a 64-year-old house wife. Urine cytology was negative. The mass at the dome of bladder was covered with normal epithelium cystoscopically. Aspiration cytology of the lower abdominal mass demonstrated no malignancy and total excision of urachal remnant with a portion of bladder wall was carried out. Histologically, the mass was an urachal cyst with granulomatous change infected with C group beta-streptococcus. Case 2: A 46 year-old male engineer complained of asymptomatic hematuria. Cystoscopic examination revealed a small bleeding lesion at the dome of bladder. Urine cytology was negative. CT scan and ultrasonography revealed a tiny cystic mass lesion with irregular density. Biopsy or aspiration cytology appeared difficult because of the size and localization of the mass. En bloc segmental resection of urachal remnant was carried out. Since intraoperative rapid histological examination of the specimen confirmed no malignancies, dissection of pelvic lymph node was not performed. Urachal cysts presented above were suspicious of malignant degeneration from findings of imaging examination. Either preoperative or intraoperative histological examination in such cases appears to be indispensable to avoid unnecessary extensive operation as well as to perform radical operation required for malignant lesions.

    Lucio’s phenomenon is an uncommon reaction characterized by severe necrotizing cutaneous lesions that occurs in patients with Lucio’s leprosy and lepromatous leprosy. It is considered by some authors as a variant of type 2 or 3 reaction. Death can occur because of blood dyscrasia or sepsis. Precipitating factors include infections, drugs and pregnancy. We report a 31-year-old female patient exhibiting both clinical and histopathological features of lepromatous leprosy and Lucio’s phenomenon presenting favorable response to treatment. We complement our report with a literature review of the Brazilian cases of Lucio’s phenomenon published in Portuguese and English. PMID:28300896

    The peritoneum is the largest serous membrane of the body and can be exposed to several injuries that may cause abnormal findings on imaging exams. Linear peritoneal calcification is remarkably rare, usually secondary to long duration peritoneal dialysis. We report an uncommon case of extensive peritoneal calcification in a 39-year-old female without long exposure to peritoneal dialysis solutions, in which peritoneal calcification could be linked to Alport syndrome and previous adverse reaction to intraperitoneal iodinated contrast. Radiologist should be aware of this and related imaging findings, know when to search for them as well as understand their clinical value. PMID:26937431

    Case studies can be useful in assessing and learning lessons from emergency situations. In this paper, different uses for disaster case studies, are explored with identification of potential pitfalls that should be avoided. In addition, ways to improve the rigor and significance of case studies are suggested. Case studies can be used as examples or as a research tool. If conducted properly, they can provide robust and compelling results. It is argued that sharing a common guide to conducting and writing case studies among all disaster risk reduction professionals could improve the quality of case study reports and thereby strengthen their value in advancing the prevention, preparedness, and management of disasters and emergencies.

    Ovarian epithelial tumors are the most common ovarian neoplasms, standing for more than half of all ovarian tumors. Borderline ovarian tumors represent a distinct group recognized by the World Health Organization (WHO), histologically distinct low ovarian carcinomas. They are tumors with low grade of malignancy with good progress and prognosis. The authors present a case of an ovarian tumor with diagnosis problems. It was the case of a 38-year-old patient with no genital pathological history, presenting hypogastric pain, dysmenorrhea, abdominal distension. The imaging performed examinations suggested an ovarian tumor with potential malignancy. The symptoms were nonspecific and the treatment was surgical. The piece was processed by paraffin inclusion and microscopically examined. Although the imaging examinations may be suggestive for potentially malignant lesions, the histopathological relation with the immunohistochemical one is the one that establishes the diagnosis. Following these examinations, there was established an ovarian borderline tumor. This is included in the lesions with low malignancy, the further evolution of the patient being a good one. The purpose of this presentation was the warning of the importance of histopathological examination linked with the immunohistochemical one, although the imaging may present lesions with malignancy criteria. Also, it was performed a literature review of borderline tumors in young women in terms of diagnosis and therapeutic conduct.

    A generic reference case for disposal of spent nuclear fuel and high-level radioactive waste in crystalline rock is outlined. The generic cases are intended to support development of disposal system modeling capability by establishing relevant baseline conditions and parameters. Establishment of a generic reference case requires that the emplacement concept, waste inventory, waste form, waste package, backfill/buffer properties, EBS failure scenarios, host rock properties, and biosphere be specified. The focus in this report is on those elements that are unique to crystalline disposal, especially the geosphere representation. Three emplacement concepts are suggested for further analyses: a waste packages containing 4 PWR assemblies emplaced in boreholes in the floors of tunnels (KBS-3 concept), a 12-assembly waste package emplaced in tunnels, and a 32-assembly dual purpose canister emplaced in tunnels. In addition, three failure scenarios were suggested for future use: a nominal scenario involving corrosion of the waste package in the tunnel emplacement concepts, a manufacturing defect scenario applicable to the KBS-3 concept, and a disruptive glaciation scenario applicable to both emplacement concepts. The computational approaches required to analyze EBS failure and transport processes in a crystalline rock repository are similar to those of argillite/shale, with the most significant difference being that the EBS in a crystalline rock repository will likely experience highly heterogeneous flow rates, which should be represented in the model. The computational approaches required to analyze radionuclide transport in the natural system are very different because of the highly channelized nature of fracture flow. Computational workflows tailored to crystalline rock based on discrete transport pathways extracted from discrete fracture network models are recommended.

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

    A 35-year-old man who had been occupationally exposed to aerosolized kaolin for 17 years in a Georgia processing plant had diffuse reticulonodular pulmonary infiltrates and an upper lobe mass. Exploratory thoracotomy, performed to evaluate the nature of the mass, revealed an 8 X 12 X 10-cm conglomerate pneumoconiotic lesion containing large amounts of kaolinite. Coincident deposition of silica in the tissue was not demonstrable by either analytic scanning electron microscopy or x-ray diffraction. The case illustrates the effect of chronic kaolin exposure on the human lung and emphasizes the need for periodic evaluation of exposed workers.

    Blue nevi are benign melanocytic lesions located in the deeper reticular dermis, consequence of failure of melanocytic migration into the dermal-epidermal junction from the neural crest. Lesions are usually asymptomatic and solitary, but may present in a multiple or agminated (grouped) pattern. The agminated subtype is formed when bluish-pigmented lesions cluster together in a well-defined area. Lesions can be flat or raised. We report the case of a patient who presented multiple bluish macules (1-3 mm in diameter) grouped on the left upper back. Dermoscopy and anatomic pathological examination were consistent with blue nevus. PMID:27828645

    Haglund's syndrome produces posterior impingement of the heel, which is caused by a posterosuperior calcaneal exostosis, known as Haglund's deformity, associated with Achilles tendinitis and retrocalcaneal bursitis. Its pathogenesis is unknown. We report two cases that were diagnosed clinically and confirmed radiographically. One patient was treated conservatively and the other underwent surgery. The diagnosis is based on clinical signs and radiological images, using the measurement of the parallel pitch lines, in a lateral radiograph of the ankle. Initial treatment is usually conservative and includes anti-inflammatory or analgesic agents, physiotherapy and low-heeled, open-heeled shoes. If conservative treatment does not relieve the pain, surgery may be necessary.

    Across the medical literature, delayed diagnosis and treatment leads to more costly and worse outcomes. Rehabilitation patients, especially those with polytrauma, often have a complex mixture of medical, social, and psychological health problems that can impair effective diagnosis and treatment. The case presentation describes the procession toward the diagnosis of ulcerative colitis in a preinjury asymptomatic male, suggesting a potential mechanism for its emergence and describing the effect of delayed diagnosis on the efficiency of rehabilitative care. As such, the differential diagnosis for early posttraumatic diarrhea should remain broad, particularly if unexplained or ineffectively controlled.

We present a case report of a 55-year-old man with an enlarging lesion on the sole of his right foot. Despite initial benign pathology the lesion continued to grow, soften in consistency and develop a foul odour. Repeat biopsy showed a well-differentiated squamous cell carcinoma and below-the-knee amputation was required. Epithelioma cuniculatum presents as a slow growing mass on the plantar aspect of the foot. Diagnosis is often delayed and may require multiple biopsies. Lesions rarely metastasise but more commonly invade locally requiring wide surgical excision.

    Most wells in oil fields are cased with metal. The feasibility of measuring low-frequency magnetic fields through such steel-cased wells is of great interest for monitoring fluid movement during production. The authors report on experimental and modeling results regarding the effect of steel casing on electromagnetic signals transmitted through them. This effect includes the attenuation and phase shift of a signal diffusing through the casing wall. Sample casings are studied under low field strength in the linear regime where the casing's electrical properties are independent of the applied signals. Frequency spectra are measured for transverse-electric and transverse-magnetic polarizations from 0.1 Hz to 1 kHz. Numerical models, developed to simulate the casing response, match the experimental data very well. Finally, studies of the effects of the earth's magnetic field and casing remnant magnetization show that these steady biases do not affect the ac signal detection.

    Psoriasis is a chronic inflammatory disease that can affect up to 1% of children. Genetic (family history of psoriasis) and environmental factors (bacterial or viral infections, stress, and trauma) are frequently involved in its occurrence. Napkin psoriasis is a particular form of psoriasis affecting mainly children younger than 2 years of age and can be classified together with other diseases under diaper rash. We present the case of a 4-month-old infant, born at term, naturally, weight and height within the normal range, who was brought to the Dermatology Clinic for the occurrence of erythematosquamous lesions in the anogenital area, buttocks and upper third of the thighs, with subsequent dissemination of lesions. The onset of symptoms began a few days after a respiratory tract infection. Initially he received treatment with systemic antibiotic and topical corticosteroid and antibiotic with unfavorable outcome. Laboratory tests revealed iron-deficiency anemia, leukocytosis, thrombocytosis, accelerated ESR, marked hepatic cytolysis, hyperphosphatemia and nasal carriage of Staphylococcus aureus. A systemic antihistamine and nonspecific desensitization treatment was administered. Topical treatment consisted in the removal of predisposing factors and irritants (diaper, urine) by rigorous hygiene, application of topical non-fluorinated cortico-steroid and use of emollients, with favorable course of the lesions. The peculiarity of the case is that the diagnosis of psoriasis was based on history, physical examination and laboratory tests, in the absence of a pathology examination to confirm the diagnosis. Pathology examination could not be performed due to patient's age as biopsy required general anesthesia.

  12. An unusual case of incaprettamento.

    2014-06-01

    Incaprettamento is a ritual strangulation that represents a method of homicide typical of the Italian Mafia. While the victim is in the prone position, he/she is bound by one end of a rope, creating a slipknot around the throat, while the other end is used to tie the limbs behind the back. Forensic investigations reveal that in most cases, the binding of the extremities and the positioning of the victim are carried out after death due to others means and are intended to hold somebody in contempt and to punish betrayers. When the victim is tied while alive, the death is caused by self-strangulation because it is impossible to maintain the legs in this forced position. Here, we describe in detail a case with a lot of similarities to incaprettamento, although we define it as atypical because of the unusual methods of the actual binding and the circumstances in which death occurred. In fact, the investigation of the crime scene, the external and internal findings, and the histologic examination result show that this is a crime of passion.

  13. [A case of diaper fetishism].

    Some people cannot obtain satisfaction from ordinary sexual relationships; instead they prefer alternative methods. They are referred to in psychiatric terminology as paraphiliacs. Fetishism is a type of paraphilia in which a person is sexually attracted to objects and some body parts. Most fetishists do not intend to cause harm to other people, but may have problems when others become involved in the problem. Underlying personality disorders extending through childhood are thought to be the source of the etiology. Perverted people do not wish to change their behavior pattern. They never seek treatment from a therapist. Psychological issues obviously play a crucial role in determining the choice of paraphilia and the underlying meaning of the sexual acts. Psychodynamic models (object relations theory, self psychology, drive theory) can shed light on the meaning of a perversion. In this case report, a 22- year-old man with diaper fetishism is presented. When family dynamics are considered, the mother has been described as psychologically distant from her son. The fetish object was recognized during childhood at around the age of four. During puberty, the fetish object became sexually attractive. Our patient exhibited his first perverted behavior when he was six years old. Later, he could control this behavior. At the age of twelve, the perverted behavior became sexually arousing. This paper emphasizes the diaper fetishism case through the patient's past psychiatric and medical history. Diaper fetishism is discussed in the light of forensic, cognitive and psychodynamic theories.

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    2008-01-01

    Introduction The KBG syndrome is a rare autosomal dominant condition, first described by Hermann et al. in 1975. Fundamental findings are: mild development delay, short stature, craniofacial dysmorphism and skeletal anomalies. Case presentation A 32 years old woman, Caucasian race, weight 57 Kg, affected by KBG syndrome was sent to our clinics for preoperative anaesthesia evaluation. She was schedules for left ossicular reconstruction under general anaesthesia for bilateral hearing loss. A psycho-motor retardation was associated to morphological anomalies such as short neck, hyperlordosis without neck extension imparirment, craniofacial anomalies and dento-skeletal abnormalities. An echocardiography showed the presence of interatrial defect with left-to-right shunt. The patient was sent to a cardiac surgery centre. Conclusion Perioperative evaluation of patients affected by KBG syndrome must take into consideration the management of difficult airways, due to the associated craniofacial dysmorphism. The possible presence of cardiac anomalies in the KBG syndrome is currently being evalueted. In this report the finding of cardiomegaly and congestion of the pulmonary circulation was attributed to presence of an interatrial defect with left-to-right shunt. The risk of cardiopulmonary failure led us to ask for a cardiac surgery consult. Perioperative management of these patients should be extremely accurate, even in the case of minor surgery, and should include also chest X-rays and echocardiography evaluation. PMID:18822138

    Introduction Lingual thyroid (LT) gland is a rare clinical entity which was found to occur due to the failure of the thyroid gland to descend to its normal cervical location during embryogenesis. The presence of an ectopic thyroid gland located at the base of the tongue may present with symptoms like dysphagia, dysphonia, upper airway obstruction or even hemorrhage at any time from infancy through adulthood. Presentation of case We are presenting a case of 5-year-old girl who presented with lingual thyroid, treated with Suppression treatment followed by elective surgical resection. Discussion Incidence of ectopic lingual thyroid gland is reported as 1:100,000. It is more common in females. Most of presentations due to oropharyngeal obstruction, including dysphagia, dyspnea and dysphonia. Investigations include thyroid function tests, neck US, Technetium scanning and C.T. Conclusion Lingual thyroid is a rare anomaly. Dysphagia and dysphonia are common presenting symptoms. Pathogenesis of this ectopic is unknown. Different types of surgical approaches have been described in the management. PMID:22096763

    2015-01-01

    Thanatophoric Dysplasia (TD) is a congenital, sporadic and the most lethal skeletal dysplasia caused by new mutation in the FGFR3 gene. At birth, it is characterized by shortening of the limbs (micromelia), small conical thorax, platyspondyly (flat vertebral bodies) and macrocephaly. TD is divided into two clinically defined subtypes: type I and II with some clinical overlap between the two subtypes. They can be differentiated by the skull shape and femur morphology. Ultrasound examination in the second trimester is often straight forward in diagnosing the congenital anomaly. We report a case of pre term fresh stillborn baby with dysmorphic facies, macrocephaly, micromelia with short stubby fingers and deep skin creases, narrow thorax and protuberant abdomen which delivered at our hospital. The ultrasound examination showed shortening of long bones with femur shaped like telephone receiver. Dysmorphic facial features and skeletal abnormalities in the baby lead us to make the diagnosis of TD type I. Because of the rarity of this condition we report this case of thanatophoric dysplasia with a short review of literature. PMID:26675119

    The objective was to report on a rare case of chondrosarcoma of the bones of the foot, and specifically the calcaneus. The patient was a 30-year-old woman with a complaint of painless nodulation on the lateral face of the calcaneus, which she had had for around eight years, which then started to present significant pain. Radiography showed a tumor with imprecise limits, compromising the calcaneus, talus and lateral malleolus. The lesion had a destructive, aggressive and osteolytic appearance, with invasion of the surrounding soft tissues and the presence of points of calcification. Amputation was performed in the middle third of the right lower leg, with a histological diagnosis of chondrosarcoma. The case evolved with local recurrence of the tumor formation and subsequent amputation in the middle third of the right thigh. One year after the second amputation, the patient evolved with metastasis from the chondrosarcoma in soft tissues throughout the body and in the lungs, and she died one year and ten months after the diagnosis was made. Chondrosarcomas that involve the calcaneus are rare in young adults, with few reports in the literature. For this reason, the present report becomes important in that it shows that even though this is a rare condition, it is present in our environment. Early investigation is essential, especially by means of imaging examinations, with the aim of diminishing the chances of malignant transformation and consequent complications, so as to avoid death.

    2007-03-01

    Chondromas are benign tumours composed of mature hyaline cartilage. We present here the first case in the English language medical literature of juxtaarticular chondroma of the temporomandibular joint in the parotid region. Within the rarity of cartilage disorders of the temporo-mandibular joint (TMJ), this particular condition is a diagnostic curiosity. The patient, a 54 year old woman, presented a right preauricular tumour of 3.5 cm. which had been developing for 4 years. It was not painful but there was a recent symptomology of TMJ dysfunction, with pain and clicks. The diagnostic possibilities of a parotid pleomorphic adenoma and of a cartilage tumour of the TMJ suggested a difficult preoperative differential diagnosis, which influenced our approach regarding therapy. The tumour was excised, preserving the parotid gland. This enabled us to confirm the histological diagnosis of chondroma, composed solely of chondroide tissue. We have described the clinical characteristics of our case, and carried out a review of the relevant literature, emphasising the differential diagnoses.

    Cryoglobulinemia is a disease mediated by antibodies with the property to precipitate at temperatures below 37°C. It can be distinguished into a primitive form (also referred to as 'essential mixed cryoglobulinemia'), and a secondary form. In the essential mixed variant a key role is played by HCV infection. The pathogenesis of mixed cryoglobulinemia is mediated by immune complexes that are the most important cause of the vasculitic phenomena, typical of the disease. However, the severity of the clinical manifestations is not always related to the serum levels of cryoglobulins and immune complexes. In our case report, a 46-year old man came to our observation with asymmetric diffuse and invalidating arthralgies, with both substitutive and additive behaviour, located at pelvic girdle, inferior limbs and elbows, associated to skin lesion vascultis-like. The remote pathological anamnesis was characterized by a previous surgically treated non-Hodgkin lymphoma, and HCV infection. Despite several attempts were done, it was not possible to reveal cryoglobulins, nor reumatoid factor in the serum. Cryoglobulins resulted positive only after the third day of hospitalization, along with a new fever attack and a worsening of the vasculitic manifestations. In conclusion, this case demonstrated that cryoglobulinemia can occur with a totally atypical sequence of clinical manifestations which can be present before and in absence of the typical laboratory proofs.

  1. [A case of tianeptine abuse].

    Tianeptine is an antidepressant agent like the selective serotonin reuptake inhibitors (SSRIs). The anxiolytic efficacy of tianeptine is similar to that of tricyclic and tetracyclic antidepressants. Very few cases have been reported in connection with excessive consumption of tianeptine. Although it is not reconciled with results of many studies on excessive consumption of tianeptine, stimulant action has been specifically emphasized on some case reports of tianeptine abuse. These reports indicate that a tolerance is developed, there is a strong mode of feeling, and there are physical withdrawal symptoms if not taken again. Treatment with tianeptine can pose a risk for addicted patients in terms of high doses as well as tolerability. In this article, we report a 24-year-old patient who abused tianeptine for one year. The biological tolerance was excellent, and hepatic parameters were not affected. The patient experienced and seeks a psychostimulant effect. The patient had a previous history of addiction to cannabis, opiates and cocaine. We concluded that the effect of tianeptine and its addiction risk at the patient who had a history of addiction to multiple substances, and spontaneously increased dose of tianeptine during the last one year up to 3000 mg per day at present. In the literature, reports of addictions to antidepressants are scarce and most of them involve agents with amphetamine-like properties, including amineptine and tranylcypromine. Other reports involving other antidepressant agents, including amitriptyline, fluoxetine and tianeptine remain exceptional.

    Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used.

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

    The present study aimed to evaluate the demographic data, diagnostic methods, therapeutic regimens and duration of therapy in 7 breast tuberculosis (BTB) cases. The data of BTB cases treated between January 2006 and December 2013 were retrospectively evaluated, with a total of 648 tuberculosis (TB) cases recorded during the 8-year period. Among these cases, 296 patients (50%) suffered from pulmonary TB, 278 (43%) from non-pulmonary TB and 45 (7%) from PTB plus NPTB. In total, 7 BTB were diagnosed, which constituted 1.08% (7/648) of all TB cases and 2.51% (7/278) of all NPTB cases. The mean age of patients was 34±9.46 years, with no pregnant or lactating women. Bilateral breast involvement was detected in only 1 case, while all cases had a BCG scar, and obtained a mean tuberculin skin test (TST) result of 14.28±6.79 mm (range, 7–26 mm). The symptoms included presence of a mass, tenderness, pain, swelling and fluctuation in the breast, with or without discharging sinuses. In 1 case, history of contact with TB was found. All patients were newly-diagnosed BTB cases, with no other organ involvement. Upon histopathological examination of breast tissue, granulomatous inflammation with typical caseous necrosis was observed in 1 case, non-caseous necrosis inflammation was detected in 2 cases, granulomatous inflammation was observed in 3 cases, and mastitis and fat necrosis inflammation was observed in 1 case. Acid-fast bacilli (AFB) staining was positive in only 2 cases, and all patient were treated with anti-TB drugs with a successful outcome and no recurrence. In conclusion, BTB is a rare form of TB and the present retrospective study reported 7 cases of BTB along with the results of histopathological examination, microbiological examination and treatment. TB must be considered when there is presence of breast masses presenting with tenderness, pain, swelling and fluctuation, with or without discharging sinuses. PMID:27882115

    2015-01-01

    This article explores the importance of quality practices in underpinning the person-centred approach at a Community Options Program (COP) case management service in northern NSW. The NSW community care sector does not have a statutory excellence body to identify, promote and support improved practices and quality and safety across community services, and therefore the COP provider decided to establish a dedicated role to focus on the quality improvement of its service. The subsequent quality improvement initiatives have included mapping the clients' journey through the service, identifying areas to standardise practice, and creating service pathways. The clients' journey was used as the framework to identify where standardised practice was required, and a robust process was implemented to develop over 25 good practice guidelines and tools that addressed the variations in practice and enabled the service pathways to be developed. Prior to trialling the guidelines and tools, staff received education sessions on the anticipated changes to practice, and the practicality and applicability of the guidelines were evaluated at the end of the trials. This information was reviewed and the guidelines were amended accordingly before being rolled out. The guidelines have been in use for over 12 months and have provided the benchmark against which to audit practice, and have resulted in key performance improvements such as an increase in client review rates and a rise in the feedback response rate from clients, with a noticeable shift in the comments about the brokered support worker to acknowledging the role of their case manager. Formalising informal supports for those clients that lived alone also increased, which means these people are less reliant on services and there is a reduced risk of social isolation.

    2010-03-01

    This review is describing different models of case management, showing their similarities and differences with regards to the way they operate. Good relationship between patient and case manager, application of the biopsychosocial model, availability of psychosocial treatment methods and rehabilitation programs, and individual treatment plan are all important factors in case management's success. Large number of studies supports the application of case management in practice as effective treatment method in treating people with severe mental disorder, particularly those, who are less co-operative. Therefore, the implementation of case management into psychiatric practice should be supported.

    Kelly, J; Stephens, I

    These case vignettes clearly illustrate the complexity which is modern psychiatric case management. In the case of Mr D, one of the salient facets of case management was medication monitoring in the context of the introduction of a new depot injection. This was a function in which nursing knowledge of medications and their side effects was undoubtedly advantageous. Any adverse experience with medication is likely to have negative ramifications regarding future compliance. Therefore, a nurse case manager is ideally suited to provide the appropriate information on psychotropic medications and to confidently answer most questions about these medications, and promptly identify any possible emerging side effects. In the case of Mr X, the management began with a practical and crisis focus involving suicide prevention. This developed into supportive psychotherapy, which required sensitive but proactive intervention and, ultimately, significant counselling skills. Mr L's case management had a different focus again, characterised by the development of a new and comprehensive case formulation and a creative nurturing of an individual's identified strength in music. The vignettes not only serve to highlight the well-established heterogeneity of mental illness, but they also importantly illuminate the heterogeneity of case management, a reality obscured in the descriptions of case management models which perhaps misleadingly have given the impression of the process as being merely a number of clearly defined tasks or functions. In actual fact, though the coordination of care appears to represent a common feature, the case management relationship remains an ever changing one, with adaptability, refined clinical skills and practical problem solving skills being the essential requisites of an effective case manager. Therefore, attempts to present this important activity in terms of any one model seem to miss the point. For the consumers of psychiatric services, the experience of

    2013-01-01

    Eccrine porocarcinoma is an extremely rare malignancy of the eccrine sweat gland. It is believed to arise from the intra-epithelial portion of eccrine sweat glands. It can either arise de novo or it can develop in a long standing eccrine poroma. It often occurs in the elderly, with the mean age of occurrence being 67 years. The tumour favours extremities, particularly the legs and feet. The propensity to form multiple cutaneous metastases is an unusual feature of eccrine porocarcinoma. It is also associated with visceral metastasis, resulting in death. An early diagnosis and prompt treatment are thus essential, owing to the aggressive behaviour of the tumour. Keeping in view its rarity of occurrence, we are hereby presenting a case of eccrine porocarcinoma which occurred in a 55–year–old female. PMID:24551693

    Lipomas are rare in oral and maxillofacial regions although they are the most common tumours of mesenchymal origin in human body. The etiology remains unclear. Various different theories explain the pathogenesis of this adipose tissue tumour and also different histological variants of oral lipoma have been given in literature. A case of intraoral lipoma occurring in mental region in a 77-year-old male is reported along with review of the literature. Wide surgical excision was performed and two-year followup showed excellent healing without any recurrence. Lipomas are benign soft tissue neoplasm of mature adipose tissue seen as a common entity in the head and neck region. Intraoral lipomas are a rare entity which may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment. It is mandatory for a clinician to diagnose intraoral lipomas using latest diagnostic methods and conservatively treat them without causing much discomfort. PMID:24592278

    Tinea incognito is a dermatophyte infection of the skin that presents atypically because it has previously been treated with imunnosuppresive medication. Herein we present a case of a middle-aged man who was initially clinically diagnosed to have plaque-type psoriasis on his arms. Over the course of two months of topical hydrocortisone and calciptriol treatment as well as phototherapy, the rash worsened. At the time of presentation to hospital the patient had a pruritic, widespread, sloughing, erythematous rash with areas of eschar. A punch biopsy skin confirmed dermatophyte fungal infection of the skin. Fungal culture was positive for Trichophyton Rubrum and the eruption resolved with systemic anti-fungal therapy. Patient specific risk factors for atypical presentation included poor hygiene and hepatatic disease.

    This case report augments a paper published in 1971 (Gunn and Fenton) in which it was indicated that automatic behaviour is a rare explanation for the crimes of epileptic patients. It was claimed that although two possible "automatic" crimes were committed by two epileptic patients among the 46 male epileptics at Broadmoor there were no such crimes committed by any of the 158 male epileptic prisoners who came into a national sample. Since then it has become clear that one man serving life imprisonment, exluded from the epileptic prisoner sample in 1967 because of a doubt about his diagnosis, is definitely epileptic and probably killed his wife during an epileptic attack or its immediate sequela.

    Maxillary cysts are a diverse group of entities that include benign and malignant odontogenic tumors. Information on the prevalence of this disease is limited. It is more common among males, and usually occurs in the second and third decade of life. The proportion of 6 to 7 year old patients with dentigerous cysts is only 9.1%. Dentigerous cysts encompass the crown of a permanent and unerupted impacted teeth. They are usually slow growing asymptomatic lesions that are not discovered until they affect surrounding organs. The aim of this study is to present an unusual case of dentigerous cyst and to inform the pediatrician about the management of a unilateral maxillary tumor in a healthy child, underlining the importance of a multidisciplinary approach of this disease.

    We report a case of a middle-age male patient, with newly HIV infection in AIDS stage diagnosis, no comorbitidies, who was hospitalized for subacute malaise, fever, self-limited unproductive cough and no bloody chronic diarrea. The diagnosis of Pneumocystis jiroveci pneumonia was performed by imagenological suspicion and stains of cysts of this pathogen with bronchoalveolar lavage samples. Treatment was initiated with oral cotrimoxazole and starting HAART with good clinical outcome. Concomitantly, an etiologic study was conducted for chronic diarrhea and through histopathological examination of colonic mucosa, numerous extracellular cystic structures Pneumocystis characteristics were observed, performing the diagnosis of extrapulmonary pneumocystosis. Extrapulmonary pneumocystosis is a rare cause of P. jiroveci infection, requires a high index of suspicion and should be approached in HIV patients with severe AIDS which is common in co-infection of various infections and is peremptory to make an etiologic diagnosis and early treatment.

    Background To report the use of En-face optical coherence tomography (OCT) in a patient treated with docetaxel and tamoxifen for breast cancer for the detection of macular edema (ME) without evidence of leakage on fluorescein angiography (FA). Case Presentation A 52-year-old woman treated for breast cancer presented with bilateral visual loss for 2 months. FA showed no significant leakage while spectral-domain OCT scans of both eyes showed foveolar and parafoveolar cystic spaces in a moderately thickened macula. En-face OCT segmented at the inner retina showed the petaloid arrangement of cystic cavities, comparable to a cystoid ME. Conclusions The combined use of tamoxifen could have potentiated the toxic effect of docetaxel on the macula. En-face OCT images may reveal a petaloid aspect of the macula due to cysts in the inner retina segmentation, when FA shows no leakage. PMID:28203192

    When an infant presents severe cyanosis which is not associated with respiratory distress, methaemoglobinemia should always be suspected. In children its main inducers are contaminated water or vegetable broths with high nitrate levels (especially spinach and carrots) used to prepare powdered formula or soups. Children affected with methaemoglobinemia have a peculiar lavender colour. Blood from the heel sticks is chocolate-brown and does not become pink when exposed to room air. Diagnosis can be confirmed by excluding other causes of cyanosis and by spectrophotometric analysis of blood for methaemoglobin. When methaemoglobin's levels reach 60% or more, the patient will collapse and become comatose and may die. Therapy with methylene blue results in prompt relief. In this article we report a case of methaemoglobinemia due to the administration of powdered formula mixed with vegetable broths to a newborn aged 16 days. Furthermore we will present a short review of literature regarding methaemoglobinemia caused by toxic agents over the last 10 years.

    Introduction Factitious cheilitis is a chronic condition characterized by crusting and ulceration that is probably secondary to chewing and sucking of the lips. Atopy, actinic damage, exfoliative cheilitis, cheilitis granulomatosa or glandularis, contact dermatitis, photosensitivity reactions and neoplasia should be considered in the differential diagnosis of crusted and ulcerated lesions of the lip. Case presentation We present a 56 year-old female with an ulcerated and crusted lesion on her lower lip. The biopsy showed granulation tissue and associated inflammation but no malignancy. Based on the tissue examination and through clinical evaluation the diagnosis of factitious cheilitis was rendered. Conclusion Thorough clinical history, utilization of basic laboratory tests and histopathologic evaluation are required to exclude other diseases and a thoruough psychiatric evaluation and treatment is vital for successful management of these patients.

    Dental anomalies can be classified in different groups: anomalies of volume, anomalies of number, anomalies of form, anomalies of position and anomalies by union. Of the latter, we distinguish between fusion, alveolus-dental gemination, concrescence, coalescence and anchylosis. Gemination is more frequent in the anterior teeth, although it can also affect the bicuspids and molars, being an anomaly of infrequent union (prevalence 0.5%). We present the case of a young male patient age 19, without medical antecedents of interest, that goes to consultation for repeated inflammatory accidents at level of the inferior left retromolar area. These episodes are caused by a semi-impacted inferior third molar that is fused to a supernumerary fourth molar, sharing its roots, crown, pulp chambers and canals. After the appropriate radiologic study and suitable planning, the semi-impacted third molar was extracted under local anaesthesia and without any other complications during or after the operation.

    A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10 cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

    Information systems that provide competitive advantages to organizations can be broadly classified into those that improve the effectiveness of a business function and those that improve the reach of information in the organization. The latter, organizational connectivity systems, can be categorized as intraorganizational and interorganizational systems. Intraorganization systems provide connectivity to function areas within the business, while interorganizational systems support the exchange of business data between independent business units. These system are not confined to a single entity but span organizational boundaries which can be national or international in scope. A series of case studies was undertaken in an effort to better understand the issues and problems associated with providing an increased flow of information within and outside of an organization. Ten issues emerged from this study. In summary, it is necessary for firms to first consider how effective their internal communications systems are before launching projects that tie the organization to external systems.

    All chemotherapeutic agents have the potential to induce hypersensitivity reactions and the repeated administration of such drugs during a cancer treatment enhances specific sensitization. Epipodophyllotoxins (etoposide and teniposide) are commonly used to treat lung, testicular, central nervous system and hematologic cancers. Hypersensitivity reactions to epipodophyllotoxins are not the most common but they have been reported. We present a case of an eight-year-old male patient, diagnosed with high risk acute lymphoblastic leukemia who received treatment with etoposide among other drugs (St. Jude XIIIB). During the first course of treatment he needed premedication to etoposide administration because of mild hypersensitivity reactions. At the beginning of a second treatment the patient presented two severe hypersensitivity reactions (acute urticaria, angioedema and hypotension) despite the use of premedication and slow infusion. We initiated a twelve steps desensitization protocol for etoposide with success in the second round allowing the administration of further doses in an ambulatory unit without hypersensitivity reactions.

    Salivary gland examination is an important part of oral examination, especially because of it's involvement in most of the systemic diseases. Patients most commonly seek medical attention when the major salivary glands like parotid and submandibular gland become enlarged or painful. The various imaging modalities practiced to check the salivary gland disorders include conventional radiography, sialography, ultrasonography, computerized tomography, radionuclide imaging and magnetic resonance imaging. Sialography is one of the oldest imaging procedures and still most commonly practiced, as it is a chair side procedure, simple to perform, and cost effective. We report the role of sialography as an adjuvant in the diagnosis of bacterial sialadenitis and sialadenosis and as a diagnostic and therapeutic aid in a case of juvenile recurrent parotitis.

It is well-proven in researches, that a herpetic encephalitis is 11.5% among sharp encephalitises. Morbidity is sporadic, some researchers specify on an increase its spring. An infection can be passed tiny and pin a way. Seasonal vibrations are not incident to the herpetic encephalitis. Two peaks of morbidity are on 5-30 years and age more senior 50 years. More than in 95% cases the virus of simple herpes of type serves as an exciter of herpetic encephalitis 1. A characteristic triad of herpetic encephalitis is the sharp feverish beginning, development of cramps of dzheksonovskogo type and violation of consciousness, developing usually after a brief respirator infection. Sometimes sudden development of cramps and loss of consciousness is preceded a fever. Example of such development of disease is made an in our work.

    Olfactory neuroblastoma (ON) is a rare type of malignant neoplasm originating from the olfactory neuroepithelial cells of the nasal cavity. ON is also known as esthesioneuroblastoma or neuroendocrine carcinoma. The malignancy accounts for <3% of tumors originating in the nasal cavity. Through the nasal cavity, ON may infiltrate the sinuses, the orbit and the cranium. The tumor is characterized by a pattern of slow growth and local recurrences. Treatment options are surgical excision or surgery combined with a radiotherapy (RT) and/or chemotherapy combination treatment. The present study reports the case of a 69-year-old patient with a mass in the nasal cavity who was treated by combined surgical excision and RT. The literature for ON and the treatment of the tumor are also discussed. PMID:26788185

    In 1994, a human and a feline case of cowpox virus infection appeared in the western part of Norway. Cowpox has not been diagnosed with certainty in Norway since the beginning of this century, when it was associated with the use of cowpox virus as a vaccine against smallpox. The human infection manifested as a spontaneously emerged, severe ulceration at the medial angle of the right eye in a 37-y-old woman, and developed into a relatively severe dermatitis. The ulcer healed slowly, leaving a scar. The feline infection was represented by a febrile, dehydrated and anorectic 6-months-old non-pedigree short-hair, with crater-like ulcers all over the body. After antibiotic and fluid therapy, revision of the skin lesions and amputation of a gangrenous toe, the cat recovered. Electron microscopy of the isolates and cultivation of virus on chorioallantoic membrane of chicken embryos confirmed the suspicion of cowpox virus infection.

    The current paper provides an overview of an evidence-based treatment, Pivotal Response Treatment (PRT), for autism spectrum disorder (ASD). The paper describes PRT principles and then illustrates the approach using two case reports. The children are preschool-aged children with high-functioning ASD. They were participating in a four-month clinical trial of PRT. At the start of treatment, they presented with significant social communication impairments, including a minimal understanding of reciprocity, limited play skills, and repetitive behaviors and speech. The paper outlines how behavioral treatment goals were identified and then how activities were designed, using principles of PRT, to target skill acquisition. Following the treatment course, both children made substantial and meaningful gains in social communication skill development.

    Methemoglobinemia; an increased concentration of methemoglobin in the blood, is an altered state of hemoglobin whereby the ferrous form of iron is oxidized to the ferric state, rendering the heme moiety incapable of carrying oxygen. The authors present a case of 49-year-old man who was admitted to the department of chest medicine with dyspnea, weakness and cyanosis in whom differential diagnosis excluded acute and chronic pulmonary and cardiovascular disease. Clinical cyanosis and low measured oxygen saturation in the presence of normal arterial oxygen tension was highly suggestive of methemoglobinemia ("saturation gap"). Methemoglobin level, measured at the acute phase of disease was elevated at 16%. Episode resolved spontaneously. Causes of methemoglobinemia was not established.

    Today many universities have the vision to become a research university, including in Indonesia. It is based on the desire to play a role in advancing science for the benefit of humanity as well as to enhance the university reputation at the international level. However, in the case of Indonesia, it can only be done by several universities, given the large number of universities with very different capabilities. In addition, another problem is human resources, infrastructure, and research funding. Various targets indicator used to determine its success include the number of publications, patents and industrial products. There is an urgent need to improve all factors that can accelerate the increase in research in Indonesia universities, and has been started by the policy of the current government.

    Fraser syndrome is a rare autosomal recessive disorder; the most consistent features are cryptophthalmos, syndactyly of fingers and toes, laryngeal stenosis, and urogenital abnormalities. We report a newborn case at day 1 of life who had multiple abnormalities, born from a consanguineous marriage. Clinically, the newborn had an ankyloblepharon on the left side, a cryptophthalmos on the right side, a syndactyly, anorectal abnormalities with ambiguous genitalia, laryngeal stenosis, and ear malformations. TDM of the cranium and orbits and the transfontanel ultrasound were normal. The abdominal ultrasound showed renal abnormalities. Right eye surgery showed a reduced cornea to an opaque thin plate clinging to the iris without an anterior chamber and a nonindividualized eyeball. The authors discuss the morphological abnormalities, the clinical and paraclinical aspects of this syndrome, its multispecialized clinical management, and the importance of prenatal diagnosis.

    Diverticular colonic disease is not as common in developing nations as in western and industrialized societies, accounting for approximately 130 000 hospitalizations per year in the United States, being diverticulitis the most frequent complication. Synchronous presentation of this complication is very rare, with only one case reported in literature. We present a patient who presented with diffuse abdominal pain. Colonoscopy was performed identifying a mass in the sigmoid colon and a perforation in the cecum. Patient underwent total abdominal colectomy with ileorectal anastomosis and protective loop ileostomy. Histopathologic examination revealed synchronous complicated diverticular disease of the sigmoid and cecum. In this report we disclose this type of atypical presentation of diverticular disease and establish that the approach taken is safe and feasible.

    We report a case of an accidental decapitation of an agriculture worker in a field. The scene investigation revealed that the worker had loosely tied a scarf tied over his face in an attempt to diminish his exposure to barley dust, to which he was allergic, while distributing the barley loads with a shovel upon a trailer. The trailer was simultaneously being loaded by a helix elevator machine and its rotating shaft suddenly caught the victim's scarf and pulled it down to the victim's neck. The rotating motion immediately tightened the scarf around the neck resulting in hanging/strangulation noose that, by continued tightening, caused decapitation of the victim. The victim's body was found on the ground by the trailer and the victim's head was discovered in the barley load in the trailer. Examination revealed that the neck was severed at the level of the second and third cervical vertebrae.

    Internal hemipelvectomy is a surgical procedure adequate for treatment of certain tumors of the pelvic girdle. Being a lower limb-preserving approach, it is a therapeutic alternative to the classical interilioabdominal amputation and hip joint disarticulation. According to Enneking's classification, there are four types of internal hemipelvectomies, although the association of different types of resection in the same procedure is feasible if necesary. This surgical approach should be correctly indicated to positively affect the patient's morbidity, mortality and quality of life. We report eight cases of internal hemipelvectomy in patients diagnosed with tumors of the pelvic girdle. We also discuss the neoadjuvant and adjuvant treatments used, along with their follow-up.

    Ocular Toxocariasis is a parasitosis caused by Toxocara catis/canis larvae localized in the eye. The most frequent clinical manifestations are the central retinal granuloma, peripheral retinal granuloma and chronic endophthalmitis. Secondary complications due to the presence of parasite in the posterior segment of the eye may have significant consequences on visual function. We present the case of a 23 years old patient, admitted for progressive decrease of the right eye BCVA during the last 6 months. After performing clinical examination and serological tests we established the diagnosis of ocular Toxocariasis. The patient presented a particular form of the disease consisting in the presence of both a central retinal granuloma and a peripheral one. We performed 23G pars plana vitrectomy and membrane peeling. VA improved as soon as the first month after surgery.

    Face recognition plays a key role in initiation and coordination of social interactions. Face is a source of many valuable information about sex, age, health and emotional state of another person. Face perception is also considered as the best developed component of human visual perception. The term prosopagnosia means the inability to recognize faces previously known, while still remaining the ability to correctly identifying other objects from the surroundings. This dysfunction can affect face recognition of famous people, family members or even own face. Affected person correctly names the object (knows, that he deals with the "face"), properly assess the emotional expression of a second person, adequately identifies the sex and age of observed person, but cannot determine who the person is. The aim of this study is to present a case of a patient complaining about emotional dysfunctions and presence of prosopagnosia symptoms following neurosurgery for arteriovenous malformation in the right temporal lobe.

    Kousseff originally described three siblings with an open sacral myelomeningocele, conotruncal cardiac malformations, low-set, posteriorly rotated ears, retrognathia, a short neck with a low posterior hairline, and renal agenesis as a new autosomal recessive condition. Open neural tube lesions and complex conotruncal cardiac defects are relatively common malformations, both as isolated defects and individually as components of syndromes, but they have been found together only rarely, as part of chromosomal syndromes or following maternal exposures. Toriello et al. reported a fourth case and suggested the eponym Kousseff syndrome for myelomeningcocele, conotruncal defects and minor facial abnormalies. We report a fifth probable case. This male infant was born by spontaneous vaginal delivery at 38 weeks gestation to a 23-year-old G{sub 2}P{sub 1001} mother. Pregnancy was complicated by an elevated alpha-fetoprotein at 16 weeks gestation, followed by an ultrasound diagnosis of an open disease. After birth, physical examination also revealed dysmorphic facies, with a bulbous nose and low-set, posteriorly rotated ears, bilateral 5th finger clinodactyly and hypotonia. Echocardiogram demonstrated complex conotruncal malformations. The patient underwent closure of the myelomeningocele but died at one month of age. Chromosomal analysis was normal (46,XY). Because conotruncal heart defects have been associated with deletions on chromosome 22, FISH analysis using a probe for the DiGeorge syndrome on the long arm of chromosome 22 was performed. It indicated no detectable deletion within this critical region on 22q11. Nonetheless there remains the possibility of a gene (or genes) located on 22q that could produce findings of this rare multiple congenital anomaly syndrome when disrupted. Therefore, further investigation on this chromosome is warranted.

    Background Globally, there has been growing evidence that suggests the effectiveness of active case finding (ACF) for tuberculosis (TB) in high-risk populations. However, the evidence is still insufficient as to whether ACF increases case notification beyond what is reported in the routine passive case finding (PCF). In Cambodia, National TB Control Programme has conducted nationwide ACF with Xpert MTB/RIF that retrospectively targeted household and neighbourhood contacts alongside routine PCF. This study aims to investigate the impact of ACF on case notifications during and after the intervention period. Methods Using a quasi-experimental cluster randomized design with intervention and control arms, we compared TB case notification during the one-year intervention period with historical baseline cases and trend-adjusted expected cases, and estimated additional cases notified during the intervention period (separately for Year 1 and Year 2 implementation). The proportion of change in case notification was compared between intervention and control districts for Year 1. The quarterly case notification data from all intervention districts were consolidated, aligning different implementation quarters, and separately analysed to explore the additionality. The effect of the intervention on the subsequent case notification during the post-intervention period was also assessed. Results In Year 1, as compared to expected cases, 1467 cases of all forms (18.5%) and 330 bacteriologically-confirmed cases (9.6%) were additionally notified in intervention districts, whereas case notification in control districts decreased by 2.4% and 2.3%, respectively. In Year 2, 2737 cases of all forms (44.3%) and 793 bacteriologically-confirmed cases (38%) were additionally notified as compared to expected cases. The proportions of increase in case notifications from baseline cases and expected cases to intervention period cases were consistently higher in intervention group than in control

    A case report is a description of a clinical case that has unique features. It may include a previously unreported clinical condition or observation of a disease, a unique use of imaging or diagnostic tool to reveal a disease, a new therapeutic intervention of a known disease, a previously unreported complication of a disease, or a new adverse event from a medication. A case report should be crisp, focused, and include few figures and references. A case report generally has a short unstructured or no abstract, a brief or no introduction, a description of the case, a discussion and a brief conclusion. Case reports are valuable sources of new and unusual information that may stimulate further research and applicability to clinical practice. Writing case reports properly is important if they are to be accepted by journals and credible and useful to readers.

    It has been reported five cases of Castleman s disease. They were admitted at Hermanos Ameijeiras Surgical-Clinic Hospital. In four out of the five cases belonged to hyaline-vascular histological variety and one case to plasmacellular variety. All the cases which belonged hyaline-vascular variety were located and one of them was complicated with sarcoma of dendritic follicular cells. The plasmacellular variety was of the multicentric type. Of the four located cases two of them were retroperitoneals and they received surgical treatment only; the case of cervical location was treated with radiotherapy and steroids and the forth one of axillary location was treated with surgical removal followed of radiotherapy. The last one case, of plasma-cell and multicentric type, was only treated with prednisone. All the patients are still alive and only the one with plasmacellular variety has symptoms yet.

    Although edible collagen casing has been commercially used in meat industry, the safety and effectiveness of collagen cross-linking with minimally invasive treatments are still big concerns for manufacturers. In this study, ultraviolet irradiation (UV) and dehydrothermal treatment (DHT) were used to improve the properties of casing. UV, DHT, and their combination (UV+DHT) significantly increased tensile strength and decreased elongation at break of casing, in which DHT showed the best performance. Swelling of casing was also partially inhibited by the treatments. Furthermore, UV and DHT slightly improved thermal stability of the casings. In addition, X-ray diffraction patterns showed the treatments caused different extents of denaturation of collagen. No obvious effects in thickness and light transparency except for surface roughness were observed in the treated casings. The physical treatments could potentially be used as safe and effective alternatives to chemical cross-linking for the production of collage casing.

    In cohort and case-control studies, confounding that arises as a result of differences in the distribution of determinants of the outcome between exposure groups leading to non-exchangeability are addressed by restriction, matching or with statistical models. In case-only studies, this issue is addressed by comparing each individual with his/herself. Although case-only designs use self-matching and only include individuals who develop the outcome of interest, issues of non-exchangeability are identical to those that arise in traditional case-control and cohort studies. In this review, we describe one type of case-only design, the case-crossover design, and discuss how the concept of exchangeability can be used to understand issues of confounding, carryover effects, period effects and selection bias in case-crossover studies.

    Gingival enlargement is defined as an overgrowth or increase in size of the gingiva. Enlargement can be of many types depending on etiologic factors like inflammation, drug-induced effects, neoplasm, hormonal imbalance, and systemic involvement (leukemia, etc). Drugs and hormonal imbalance are the most common causes of gingival enlargement. Nonspecific conditioned enlargement, or pyogenic granuloma, is considered an exaggerated conditioned response to minor trauma or chronic irritation. Pyogenic granuloma occurring in the oral cavity is a common phenomenon. However, simultaneously occurring generalized pyogenic granuloma in the oral cavity is a rare entity. Generalized pyogenic granuloma on the back and skin have been reported. This is the first case report of generalized pyogenic granuloma in the oral cavity. A 19-year-old male patient reported with a complaint of difficulty in mastication and generalized swelling of the gingiva that developed within a span of 15 days. Family and systemic history were noncontributory. Based on the clinical findings, histopathology report, and immunohistochemistry result, the patient was diagnosed with generalized pyogenic granuloma. Scaling and root planing were performed as the first phase of therapy followed by external bevel gingivectomy. The patient was followed for 3 months. The patient was advised to visit the clinic for regular maintenance visits for 1 year, as pyogenic granuloma has a tendency to recur.

    Histoplasma capsulatum infection is, for the most part, asymptomatic or of little clinical consequence. Disseminated infection due to H. capsulatum is rather uncommon. Clinically apparent infection of central nervous system (CNS) is rare, and involves in 10 to 50% of patients with disseminated histoplasmosis. Although CNS histoplasmosis is frequently fetal or only discovered as an autopsy, some patients can be effectively treated with anti-fungal agents. We describe a 44-year-old civil man who is engineering contractor with headache without evidence of systemic infection. Magnetic resonance imaging showed enhancing masses in the third and forth ventricles, right interpeduncular cistern, and right cerebello-pontine angle. After biopsy of what was presumed to be a malignant lymphoma, the patient died of rapidly progressive multiple cerebral infarctions. The autopsy revealed the CNS histoplasmoma disseminating systemically. And we finally diagnosed him as histoplasmoma by gene analysis. It was extremely difficult to make a diagnosis based on his physical and radiological findings because it should be included in the differential diagnosis of a well or ring enhanced lesion. It is very important to ask patients about their birthplace, past illness, occupation, and where they had traveled. In the present case, the patient working for the construction has visited many countries including the African Continent and Central America. Clinicians should maintain a high index of suspicion in patients who are from any area endemic for histoplasmosis. The clinical, radiological and pathological features of this infection were reviewed in this report.

    The English-language medical case literature was searched for cases of apparent or alleged child abuse between the years 1969 and 2001. Three-hundred and twenty-four cases that contained detailed individual case information were analyzed yielding 54 cases in which someone was recorded as having admitted, in some fashion, to have shaken the injured baby. Individual case findings were tabulated and analyzed with respect to shaking as being the cause for the injuries reported. For all 54 admittedly-shaken-infant cases, the provided details regarding the shaking incidents and other events are reported. Data in the case reports varied widely with respect to important details. Only 11 cases of admittedly shaken babies showed no sign of cranial impact (apparently free-shaken). This small number of cases does not permit valid statistical analysis or support for many of the commonly stated aspects of the so-called shaken baby syndrome.

    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.

    Subjects and Methods. We analysed 5000 cerebrovascular ultrasound records. A total of 0.4% of the patients had common carotid artery occlusion (CCAO). Results. The mean age was 59.8 ± 14.2 years, and the male/female ratio was 2.33. The most frequent risk factors were hypertension, ischaemic heart disease, dyslipidemia, diabetes mellitus, and smoking. Right-sided and left-sided CCAO occurred in 65% and 30% of the cases, respectively, and bilateral occlusion was detected in one case (5%). Patent bifurcation was observed in 10 cases of CCAO in which the anterograde flow in the ICA was maintained from the external carotid artery with reversed flow. In two of the cases, the occluded CCA was hypoplastic. The aetiology of CCAO in the majority of cases was the atherosclerosis (15 cases). The male/female ratio was higher in the patients with occluded distal vessels, and the short-term outcome was poorer. Only two cases from this series underwent revascularisation surgery. Spontaneous recanalisation was observed in one case. Conclusions. The most frequent cause of CCAO was atherosclerosis. The outcome is improved in the cases with patent distal vessels, and spontaneous recanalisation is possible. Treatment methods have not been standardised. Surgical revascularisation is possible in cases of patent distal vessels, but the indications are debatable. PMID:24167740

    A case is presented of a premature newborn of 27 weeks gestation and weighing 420 grams who was delivered as a result of a maternal pre-eclampsia and retarded intra-uterine growth. During the 125 days of hospitalisation, an individual care plan based on the Virginia Henderson model was devised and applied to both the child and her parents using NANDA diagnostics, interventions according to the NIC classification, and the expected results according to the NOC classification. The Marjory Gordon functional patterns were used for the initial assessment. By applying the pre-term newborn (PTNB) plan, all their needs were provided and were modified throughout the hospital stay, with new needs that were added to the established ones. These required a continuous assessment with the subsequent adapting of the care plan. Likewise, the care required by the parents varied from the initial grief due to the possible loss of their child to learning the alarm signs and the home care that their child would need. The child was finally discharged weighing 2900 grams and with normal neurological and psychomotor development, although with a lower weight appropriate to her age. Currently, at 2 years old, the child has a normal neurological and psychomotor development, but with weight and size lower than the P(3) percentile. She requires speech therapy treatment due to paralysis of the right vocal cord.

    Schwannomas are generally benign, slow growing tumors. They are rarely observed in the gastrointestinal tract with the most common site being the stomach. These tumors are usually asymptomatic. The preoperative diagnosis via endoscopy is a challenging issue due to the difficulty of differentiation from other submucosal tumors. A 54-year-old woman presented with epigastric pain persisting for the last 10 months. Upper endoscopy revealed an elevated submucosal mass of the gastric antrum. The overlying mucosa was normal. Biopsy specimens yielded only unspecific signs of mild inactive chronic inflammation. Endoscopic ultrasound examination noted a hypoechoic homogeneous mass lesion located in the gastric antrum. The mass appeared to arise from the muscularis propria, and there was no perigastric lymphadenopathy. A contrast-enhanced computed tomography scan identified a homogeneous round mass and arising from the antrum of the stomach. Submucosal tumor was suspected and surgical intervention was recommended. The patient underwent an elective laparoscopic partial gastrectomy. The histopathologic features and immunohistochemical-staining pattern were consistent with a benign gastric schwannoma. Our patient shows no recurrence with a follow-up of one year. The definitive diagnosis of gastric schwannomas requires immunohistochemical studies. Complete margin negative surgical resection, as in this case, is the curative treatment of choice. The clinical course is generally benign. PMID:28028429

    Aortitis is a nonspecific term that describes an inflammation of the aortic wall caused by inflammatory, infectious, paraneoplastic and idiopathic diseases. The symptoms are variable and nonspecific; therefore a high level of clinical suspicion is required to diagnose it. It is often an incidental finding while looking for other diagnoses and it is confirmed mainly through imaging studies. We report three cases of aortitis: A 29-year-old woman presenting with alopecia, oral and nasal ulcers and positive antinuclear antibodies. A CAT scan showed a segmental thickening of thoracic aorta, with dilated and stenotic areas. She was successfully treated with steroids, hydroxychloroquine, cyclophosphamide and azathioprine. A 41-year-old male presenting with dorsal pain and cough. The CAT scan showed an extra-intimal thickening of the descending aorta and stenosis of the celiac artery. The final diagnosis was a polyangiitis and was treated with steroids, cyclophosphamide and azathioprine. A 28-year-old woman presenting with pain in the left upper abdomen. Imaging studies showed a thickening of the aortic arch and subclavian artery. The final diagnosis was sarcoidosis and the patient was treated with prednisone.

    The current study reported the case of a 35-year-old male that presented with antifreeze poisoning. The clinical manifestations, laboratory investigations and treatments were analyzed, and the obtained results were compared with those in previous reports. Subsequent to consuming antifreeze, the patient mainly presented nausea and agitation, without disturbance of consciousness. Laboratory investigations indicated severe metabolic acidosis, renal dysfunction and hyperkalemia. The patient underwent hemodialysis and his condition was significantly improved on the day of admission. Renal function gradually deteriorated, but was eventually improved due to treatment, including hemodialysis, mannitol for catharsis, furosemide for diuresis, Xuebijing for the removal of blood stasis and detoxication, and reduced glutathione for the protection of major organs. The patient was discharged 1 month after hospital admission. In conclusion, the significance and clinical manifestations of antifreeze poisoning should be identified in clinical practice, and active hemodialysis should be provided. The aim of the current study was to summarize the clinical manifestations and treatments of patients with antifreeze poisoning, and to advance the recognition of antifreeze poisoning. PMID:28352354

    Presbyacusis is one among the many socio-medical problems, which is considered as a hidden disability. The hearing impairment in elderly people is described as presbyacusis. Hearing problem among elderly people is a major issue and a person with hearing loss may be unable to hear doorbells and alarms, to respond while talking with anyone, etc. All this can make them feel frustrated, lonely, and depressed. It is the third most common chronic condition after arthritis and hypertensive diseases among elders. Hearing loss can be improved by using the hearing aids. Hearing aids work well for some while for others; it may not be a perfect solution due to many reasons such as some people do not buy aids that meet their needs, incorrect amplification adjustments, low custom design, etc. In classics of Ayurveda this ailment has been described as karnabaadhirya under the heading of ear diseases. Karnapurana (Instillation of medicated oil into the external auditory canal) is one of the major treatments for ear diseases explained in classics. Clinical observation has shown its effectiveness in the management of presbyacusis.

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

  8. A Case of Dermatitis Neglecta.

    Dermatitis neglecta (unwashed dermatosis) presents as pigmented hyperkeratotic plaques with adherent scales which clinically resembles psoriasis. This condition is the result of avoiding washing the affected areas, so the lesions are characteristically resolved with normal washing or with gentle wiping from an alcohol swab. We report a 29-year-old man who presented with an asymptomatic hyperkeratotic scaly plaque on umbilicus. A skin biopsy was done under the clinical impression of psoriasis. During skin biopsy, gentle swabbing with H2O2 and saline gauze was done. The patient revisited our clinic 10 days after the skin biopsy and the hyperkeratotic lesion had cleared. Histologic examination showed orthokeratotic hyperkeratosis and anastomosing rete ridges. There has been no previous report of dermatitis neglecta with histologic confirmation, and so this case could be the first report to provide the histologic characteristics of dermatitis neglecta. Because this condition might be overlooked and underdiagnosed, recognizing its existence and cause are important to avoid unnecessary biopsies and potentially aggressive therapeutic measures.

    Bell, Matthew S.; Tam, William F. S.

    1992-01-01

    This paper describes the achievements made on the Advanced Solid Rocket Motor (ASRM) case insulation design and development program. The ASRM case insulation system described herein protects the metal case and joints from direct radiation and hot gas impingement. Critical failure of solid rocket systems is often traceable to failure of the insulation design. The wide ranging accomplishments included the development of a nonasbestos insulation material for ASRM that replaced the existing Redesigned Solid Rocket Motor (RSRM) asbestos-filled nitrile butadiene rubber (NBR) along with a performance gain of 300 pounds, and improved reliability of all the insulation joint designs, i.e., segmented case joint, case-to-nozzle and case-to-igniter joint. The insulation process development program included the internal stripwinding process. This process advancement allowed Aerojet to match to exceed the capability of other propulsion companies.

    With the increase in global transportation, imported malaria has become a significant public health concern in Japan. In the present study, we retrospectively analyzed all imported malaria cases in Okinawa Prefecture from 1988 to 2012. In that period, 23 patients with imported malaria were admitted to the University of the Ryukyus Hospital. Malaria types observed included Plasmodium falciparum (14 cases), P. vivax (7 cases), combined P. falciparum and P. ovale (1 case), and combined P. vivax and P. malariae (1 case). All cases were resolved by anti-malarial treatment. The clinical data from these patients highlights the importance of collecting patient travel history and ensuring an adequate supply of both diagnostic test and drug treatments in Okinawa.

    Leake, D.B.; Kinley, A.; Wilson, D.

    1996-12-31

    The ability of case-based reasoning (CBR) systems to apply cases to novel situations depends on their case adaptation knowledge. However, endowing CBR systems with adequate adaptation knowledge has proven to be a very difficult task. This paper describes a hybrid method for performing case adaptation, using a combination of rule-based and case-based reasoning. It shows how this approach provides a framework for acquiring flexible adaptation knowledge from experiences with autonomous adaptation and suggests its potential as a basis for acquisition of adaptation knowledge from interactive user guidance. It also presents initial experimental results examining the benefits of the approach and comparing the relative contributions of case learning and adaptation learning to reasoning performance.

    Ameloblastoma is the most common odontogenic tumour. The tumour has been described as a benign but locally invasive polymorphic neoplasm. Hybrid lesions have been described, which combine histological features of desmoplastic and conventional ameloblastoma. The hybrid ameloblastoma is rare and only few cases have been reported worldwide. We present two cases seen from a review of 195 ameloblastoma cases seen over a ten year period. The cases presented with clinical features of the conventional ameloblastoma such as bucco-lingual bone expansion and multilocular radiololucency. Larger clinical series of hybrid ameloblastoma need to be reviewed in order to better characterize the clinical behaviour, aggressiveness and prognosis of this rare variant of ameloblastoma.

In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

  8. The strange case of the Freudian case history: the role of long case histories in the development of psychoanalysis.

    PubMed

    Sealey, Anne

    2011-01-01

    Sigmund Freud's five long case histories have been the focus of seemingly endless fascination and criticism. This article examines how the long case-history genre developed and its impact on the professionalization of psychoanalysis. It argues that the long case histories, using a distinctive form that highlighted the peculiarities of psychoanalytic theory, served as exemplars in the discipline. In doing so, the article extends John Forrester's work on "thinking in cases" to show the practical implications of that style of reasoning. The article illustrates how the form disappeared once the theoretical basis of the movement was set. The genre never became institutionalized, although the content of the five long case histories did, because of Freud's accepted role as theoretician of psychoanalysis.

  9. The electrical resistivity method in cased boreholes

    1991-05-01

    The use of downhole current sources in resistivity mapping can greatly enhance the detection and delineation of subsurface features. The purpose of this work is to examine the resistivity method for current sources in wells cased with steel. The resistivity method in cased boreholes with downhole current sources is investigated using the integral equation (IE) technique. The casing and other bodies are characterized as conductivity inhomogeneities in a half-space. For sources located along the casing axis, an axially symmetric Green's function is used to formulate the surface potential and electric field (E-field) volume integral equations. The situations involving off-axis current sources and three-dimensional (3-D) bodies is formulated using the surface potential IE method. The solution of the 3-D Green's function is presented in cylindrical and Cartesian coordinate systems. The methods of moments is used to solve the Fredholm integral equation of the second kind for the response due to the casing and other bodies. The numerical analysis revealed that the current in the casing can be approximated by its vertical component except near the source and the axial symmetric approximation of the casing is valid even for the 3-D problem. The E-field volume IE method is an effective and efficient technique to simulate the response of the casing in a half-space, whereas the surface potential approach is computationally better when multiple bodies are involved. Analyzing several configurations of the current source indicated that the casing response is influenced by four characteristic factors: conduction length, current source depth,casing depth, and casing length. 85 refs., 133 figs., 11 tabs.

    A retrospective study of onychomycohosis by molds was carried out during a 14-year period (1992-2005). All cases were clinically and mycologically proven (repetitive KOH and culture) and then each of the molds was identified. A total of 5,221 cases of onychomycosis were evaluated, 78 of which were molds (1.49%). Mean patient age was 44.1 years. 75/78 cases occurred in toenails. Associated factors were detected in 39/78 (50.0%) cases, with the major ones being: peripheral vascular disease, contact with soil, and trauma. The most frequent clinical presentation was distal and lateral subungual onychomycosis (DLSO), in 54/78 cases (69%). The most frequent causative agents were: Scopulariopsis brevicaulis in 34/78 cases and Aspergillus niger in 13/78 cases. Onychomycoses by molds are infrequent; in this study they accounted for 1.49% of cases. The clinical features are virtually similar to those caused by dermatophytes, which makes the clinicomycological tests necessary.

    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

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    Abstract Background: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. Case Presentation: This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes. MicroPerc set 4.85F sheath was used to explore the pelvic ureter, thus avoiding the need to dilate the ureteral meatus or having to use the safety guide. Patients did not require a postoperative stent and were discharged within 24 hours of the procedure. Conclusion: Use of microureteroscopy proved satisfactory in the two cases of children and it allows diagnosis and treatment of ureteral pathology in pediatric patients. PMID:27579414

  16. Case management in France: an economic perspective.

    Case management is currently an important issue in France. Because neither service providers nor consumers pay for case management in this country, a cost-benefit analysis is often required by the organizations that do pay. Given the context of French social policy and the current focus on justifying case management through cost-benefit analysis, we have developed a way to evaluate its costs. This article presents the limitations of standard economic choice theory, provides a methodology based on the principles of limited rationality, and gives the results of an evaluation of four case management programs. The article provides a method to measure case management costs and efficiency, as well as the willingness of consumers to pay for services.

  17. Are nested case-control studies biased?

    It has been recently asserted that the nested case-control study design, in which case-control sets are sampled from cohort risk sets, can introduce bias (“study design bias”) when there are lagged exposures. The bases for this claim include a theoretic and an “empirical evaluation” argument. Both of these arguments are examined and found to be incorrect. Appropriate methods to explore the performance of nested case-control study designs, analysis methods, and compute power and sample size from an existing cohort are described. This empirical evaluation approach relies on simulating case-control outcomes from risk sets in the cohort from which the case-control study is to be performed. Because it is based on the underlying cohort structure, the empirical evaluation can provide an assessment that is tailored to the specific characteristics of the study under consideration. The methods are illustrated using samples from the Colorado Plateau uranium miners cohort. PMID:19289963

  18. Advance modern medicine with clinical case reports

    PubMed Central

    2014-01-01

    Randomized clinical trial (RCT) can fail to demonstrate the richness of individual patient characteristics. Given the unpredictable nature of medicine, a patient may present in an unusual way, have a strange new pathology, or react to a medical intervention in a manner not seen before. The publication of these novelties as case reports is a fundamental way of conveying medical knowledge. Throughout history there have been famous case studies that shaped the way we view health and disease. Case reports can have the following functions: (I) descriptions of new diseases; (II) study of mechanisms; (III) discovery new therapies; (IV) recognition of side effects; and (V) education. Before submitting a case report, it is worthwhile to refer to the Case Report Check Sheet described by Green and Johnson [2006]. PMID:25525572

  19. Emotionally intelligent case managers make a difference.

    Emotional intelligence is a skill necessary for case managers because of the diversity of their work, the multiple stakeholders they have to deal with on daily basis, and the increased potential for conflict. Managers and administrators need to be cognizant of the role emotional intelligence plays in employee performance and the importance of developing training programs to assist case managers in learning to deal with change and conflict. Case managers must assume responsibility for their actions and work to develop and improve their emotional intelligence skills set. Ultimately, patients and work associates will appreciate the case manager's efforts. Finally, case managers will find work an enjoyable experience and look forward to new opportunities the future holds.

    Ashy dermatosis is a typically asymptomatic disease of unknown origin that causes symmetrical gray spots to appear on the trunk and extremities. We report 2 cases of ashy dermatosis with unilateral distribution. To our knowledge, only 5 cases of ashy dermatosis with unilateral lesion have been reported so far. Case 1: an 11-year-old woman presented with asymptomatic slate-gray pigmented plaques on the left trunk and left upper arm. The skin biopsy specimen demonstrated a mild lymphohistiocytotic infiltrate in the upper dermis with epidermal and dermal melanosis. Q-Switched ruby laser did not improve such lesions. Case 2: a 21-year-old man was referred to our hospital because of asymptomatic slate-gray pigmented plaques on the left trunk and left upper arm. Histopathological findings were compatible with a mild lymphocytic infiltration with melanin incontinence in the upper dermis. The mechanism that governs unilateral distribution of ashy dermatosis, including in our cases, remains unclear. PMID:21897817
