    Bradyarrhythmias are common clinical findings consisting of physiologic and pathologic conditions (sinus node dysfunction and atrioventricular [AV] conduction disturbances). Bradyarrhythmias can be benign, requiring no treatment; however, acute unstable bradycardia can lead to cardiac arrest. In patients with confirmed or suspected bradycardia, a thorough history and physical examination should include possible causes of sinoatrial node dysfunction or AV block. Management of bradycardia is based on the severity of symptoms, the underlying causes, presence of potentially reversible causes, presence of adverse signs, and risk of progression to asystole. Pharmacologic therapy and/or pacing are used to manage unstable or symptomatic bradyarrhythmias. PMID:27484658

    Symptomatic gastroesophageal reflux occurs daily in an estimated 7% of adults and weekly or monthly in 29%. Untreated it can lead to esophageal erosions, ulceration and stricture formation. The pathogenesis is often multifactorial: defects in the function of the lower esophageal sphincter, esophageal clearance mechanisms and gastric emptying combine to produce frequent lengthy periods during which the lower esophagus is bathed in regurgitated acid. In most patients reflux disease is easily recognized as recurrent heartburn, regurgitation or dysphagia, or a combination. When acute chest pain or respiratory illness is the primary presenting complaint the patient needs particularly careful investigation to determine whether the symptoms are due to a primary cardiac or respiratory condition, are secondary to gastroesophageal reflux alone or represent a combination of disorders. Endoscopy with biopsy and long-term pH monitoring are the most reliable ways of determining whether reflux disease is present. Additional investigations, such as exercise testing, cardiac catheterization or inhalation challenge, may be needed in patients with cardiac or respiratory symptoms. Treatment should follow a stepped-care approach and in most patients should begin with changes in lifestyle, including dietary manipulation, reducing alcohol and cigarette consumption, and raising the head of the bed, together with appropriate use of antacids or alginate-antacid combinations. H2-receptor antagonists and agents to improve both gastric emptying and the tone of the lower esophageal sphincter may be added in sequence. Most patients will respond well to this regimen. Surgery should be considered only for those with intractable symptoms or with complications (e.g., stricture formation, bleeding, development of dysplastic epithelium in those with Barrett's esophagus, or secondary pulmonary disease that does not respond to medical management). It is successful in 85% of well-selected patients and

  3. Clinical presentation of inappropriate sinus tachycardia and differential diagnosis.

    Inappropriate sinus tachycardia (IST) is a syndrome characterized by a sinus tachycardia not related to a medical condition, to a physiological response, or to medication or drugs and associated with symptoms, often invalidating and altering the quality of life of affected patients. It occurs predominantly in adolescents and young adults, and in the female sex. The diagnosis requires a complete work-up in order to exclude other causes of sinus tachycardia and one or several additional tests: 24-h ECG ambulatory recordings, echocardiogram, exercise testing, and autonomous nervous system assessment. It should be differentiated from the postural orthostatic tachycardia syndrome, with which it shares a number of symptoms, and other supraventricular tachycardias originating in the high right atrium. An electrophysiological study should be considered in selected cases in order to differentiate IST from other supraventricular tachycardias. The mechanism is still unclear, and possible etiologies may include intrinsic abnormality of the sinus node, autonomic dysfunction, hypersensitivity of the sinus node to catecholamines, blunted vagal system, or a combination of the above. The authors emphasize the wide spectrum of clinical presentations and the need to better define the IST and the criteria required to ascertain its diagnosis. PMID:26329720

    Full Text Available Objective: to refine the pattern of clinical manifestations of epileptic autonomic auras (EAA and to reveal clinical, electroencephalographic, and neuroimaging ratios. Patients and methods. Eighteen patients (8, 41% men and 10, 59% women aged 9 to 27years (mean 18±5years were examined. The examination encompassed analysis of history data, clinical and neurological studies, long-term video-assisted electroencephalographic monitoring, and magnetic resonance imaging (MRI of the brain. Results. In most patients (n = 12, 67%, the symptoms of EAA corresponded to the criteria for abdominal one. In the other patients, the clinical manifestations resembled autonomic paroxysms as attacks of panic. Interictal pathological changes on an electroencephalogram (EEG were present in the frontal, temporal, and frontotemporal regions in 4 (22%, 6 (33%, and 7 (39% patients, respectively, as well as in both the left and right hemispheres without significant differences. Pathological EEG changes were not found in one case. MRI detected that 13 (72% patients had structural changes that were potentially eliptogenic. Conclusion. The clinical symptoms of EAA give information on the site of a primary pathological focus. It is necessary to differentiate EAA from non-epileptic paroxysmal states. The autonomic phenomena of epileptic genesis help study the functional organizations of the autonomic nervous system.

    Mucopolysaccharidosis type IVA (MPS IVA) was described in 1929 by Luis Morquio from Uruguay and James Brailsford from England, and was later found as an autosomal recessive lysosomal storage disease. MPS IVA is caused by mutations in the gene encoding the enzyme, N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Reduced GALNS activity results in impaired catabolism of two glycosaminoglycans (GAGs), chondroitin-6-sulfate (C6S) and keratan sulfate (KS). Clinical presentations of MPS IVA reflec...

    Full Text Available At present, the problem of infective endocarditis (IE remains relevant for clinicians of different specialties, including rheumatologists. The distinctive feature of present-day IE is its polyetiological pattern due to a broad spectrum of pathogens. The lecture highlights in detail clinical picture of the disease, laboratory and instrumental findings. It presents current international diagnostic criteria for IE. The obvious clinical polymorphism, subtle symptoms, and monosyndromic onset as masks, all increases the significance of differential diagnosis of IE, in early disease stages in particular. Main approaches to differentiating IE from diseases posing the greatest differentially diagnostic challenges are set forth.

    The mouth is a mirror of health or disease, a sentinel or early warning system. The oral cavity might well be thought as a window to the body because oral manifestations accompany many systemic diseases. In many instances, oral involvement precedes the appearance of other symptoms or lesions at other locations. Oral lichen planus (OLP) is a chronic mucocutaneous disorder of stratified squamous epithelium of uncertain etiology that affects oral and genital mucous membranes, skin, nails, and scalp. LP is estimated to affect 0.5% to 2.0% of the general population. This disease has most often been reported in middle-aged patients with 30-60 years of age and is more common in females than in males. The disease seems to be mediated by an antigen-specific mechanism, activating cytotoxic T cells, and non-specific mechanisms like mast cell degranulation and matrix metalloproteinase activation. A proper understanding of the pathogenesis, clinical presentation, diagnosis of the disease becomes important for providing the right treatment. This article discusses the prevalence, etiology, clinical features, oral manifestations, diagnosis, complications and treatment of oral LP. PMID:26120146

    Hereditary angioedema (HAE) is a rare disorder first described in 1888 by Sir William Osler. Since then, our understanding of this condition has increased tremendously. This article reviews the historical aspects, classification, pathophysiology, clinical presentation, and laboratory diagnosis of HAE. A review was performed of historical and current literature of HAE. HAE I and II are related to insufficient production of C1-esterase inhibitor (C1-INH) or production of a dysfunctional C1-INH protein, respectively. HAE III is not related to C1-INH deficiency and the pathogenesis is unknown. Bradykinin appears to be the main mediator responsible for angioedema in patients with C1-INH deficiencies. Angioedema of the extremities, face, and upper airway along with gastrointestinal angioedema are the most common clinical features in HAE. The laboratory tests that are most commonly used in the diagnosis of HAE include C4, C1-INH concentration, and C1-INH function. Advances in our understanding of the pathogenesis of HAE have led to several advances in the therapy of this disease. Despite our more thorough understanding of the genetics and pathophysiology of HAE, many questions remain unanswered. PMID:21262092

    2012-01-01

    Full Text Available Objective: Traumatic diaphragmatic injuries are rare, but potentially life-threatening due to herniation of abdominal organs into the pleural cavities. They can be easily overlooked on initial diagnostics and a high index of suspicion is required. The aim of this retrospective study was to analyze the clinical presentation, diagnostic methods and surgical management of patients with diaphragmatic rupture at our institution. Methods: A retrospective study was performed to analyze our experience with patients suffering from traumatic diaphragmatic rupture. Charts were reviewed for sex, age, side-location, concomitant injuries, time-to-diagnosis, diagnostic methods, surgical approach and outcome. Results: Fourteen patients (median age: 46 yrs, range 18–71, 9 male, 5 female with diaphragmatic injuries (left side: 10, right side: 4 were treated between July 2003 and September 2011. Mechanism of injury was a penetrating trauma (14%, blunt trauma (50% and others (36%. Associated abdominal injuries included spleen rupture (n=3, liver laceration (n=2, abdominal wall laceration (n=2 and gastric perforation (n=1. Computed tomography was the most sensitive diagnostic method. All patients underwent trans-abdominal repair of the diaphragmatic defect (direct suture: 10, prosthetic mesh insertion: 4. Associated abdominal procedures included splenectomy (n=3, liver packing (n=2, abdominal wall reconstruction (n=2 and partial gastric resection (n=1. Morbidity and hospital mortality rate were 36% and 0%, respectively. Median postoperative hospital stay was 17 days (range: 7–40 days. Conclusion: Morbidity and mortality of diaphragmatic ruptures are mainly determined by associated injuries or complications of diaphragmatic herniation like incarceration of viscera or lung failure. Early diagnosis helps to prevent severe complications. Spiral CT-scan is the most reliable tool for acute diagnosis of diaphragmatic rupture and associated visceral lacerations

  12. Coeliac disease - clinical presentation and diagnosis by anti tissue transglutaminase antibodies titre in children

    International Nuclear Information System (INIS)

    Objective: To study the spectrum of clinical presentation of coeliac disease and the role of IgA anti-tissue transglutaminase antibodies titer in the diagnosis and effect of gluten-free diet on such titers in children. Methods: The prospective study was conducted in the paediatric department of Combined Military Hospital, Kharian from Sep 2011 to Sep 2012. Children of 1-12 years of age presenting with chronic diarrhoea, malnutrition and failure to thrive were included regardless of gender, socioeconomic status, ethnicity and geographical distribution. Anti-tissue transglutaminase antibodies titers were done on enrolment. Patients with levels more than 30u/ml were enrolled. They were advised strict gluten-free diet for six months. These titers were repeated after six months to document the effect of gluten-free diet on these titers. Paediatric endoscopy and duodenal biopsy facilities were not available at the study site, so the response was monitored through titers. Data was analysed using SPSS-20. Results: Out of 61 patients with IgA levels more than 10 u/ml, 52 (85.24%) were found to have a positive (>30u/ml) anti-tissue transglutaminase antibodies titers with a mean value of 42.67+-7.60 U/ml. These 52 patients were then put on a trial of gluten-free diet for six months after which significant reduction in titer was noticed, with a mean value of 13.25+-2.59 U/ml. This reduction in titer was associated with marked clinical improvement and regression of symptoms. Frequency of different clinical features in descending order revealed that chronic diarrhoea, abdominal distension, iron deficiency anaemia, failure to thrive, pallor and rickets were present in 38 (73.1%), 30 (57.7%), 29 (55.8%), 29 (53.8%), 28 (53.8%) patients respectively. Conclusion: Chronic diarrhoea, failure to thrive, pallor, abdominal distention and iron deficiency anaemia were common modes of presentation. The antibodies were strongly positive in most of the cases. All children showed significant

    2004-09-01

    Melioidosis, an infectious disease caused by Burkholderia pseudomallei is an emerging disease with high impact on animals and man. In different animal species, the clinical course varies and delayed diagnosis poses risks for the dissemination of the agent in non-endemic areas. Not only migration and transport of animals around the world but also tourism increases the risk that melioidosis can leave its endemic boundaries and establish itself elsewhere. Detection of the agent is a major challenge, as the agent has to be handled in laboratories of biosafety level 3 and test kits are not yet commercially available. Veterinarians and doctors should be aware of melioidosis not only as an agent of public interest but also in terms of a bioterrorist attack. The aim of this review is to describe the agent, its aetiology, the manifestation in a variety of animal species as well as to describe diagnostic procedures, typing techniques and countermeasures.

    2015-07-01

    Autosomal dominant polycystic kidney disease (ADPKD) is the leading genetic cause of end-stage renal disease (ESRD) worldwide. Its prevalence is evaluated according to studies and population between 1/1000 and 1/4000 live births and it accounts for 6 to 8% of incident ESRD patients in developed countries. ADPKD is characterized by numerous cysts in both kidneys and various extrarenal manifestations that are detailed in this review. Clinico-radiological and genetic diagnosis are also discussed. Mutations in the PKD1 and PKD2 codifying for polycystin-1 (PC-1) and polycystin-2 (PC-2) are responsible for the 85 and 15% of ADPKD cases, respectively. In primary cilia of normal kidney epithelial cells, PC-1 and PC-2 interact forming a complex involved in flow- and cilia-dependant signalling pathways where intracellular calcium and cAMP play a central role. Alteration of these multiple signal transduction pathways leads to cystogenesis accompanied by dysregulated planar cell polarity, excessive cell proliferation and fluid secretion, and pathogenic interactions of epithelial cells with an abnormal extracellular matrix. The mass effect of expanding cyst is responsible for the decline in glomerular filtration rate that occurs late in the course of the disease. For many decades, the treatment for ADPKD aims to lessen the condition's symptoms, limit kidney damage, and prevent complications. Recently, the development of promising specific treatment raises the hope to slow the growth of cysts and delay the disease. Treatment strategies targeting cAMP signalling such as vasopressin receptor antagonists or somatostatin analogs have been tested successfully in clinical trials with relative safety. Newer treatments supported by preclinical trials will become available in the next future. Recognizing early markers of renal progression (clinical, imaging, and genetic markers) to identify high-risk patients and multidrug approaches with synergistic effects may provide new opportunities

Tellez-Zenteno1, Cesar Serrano-Almeida2, Farzad Moien-Afshari11Division of Neurology, University of Saskatchewan, Saskatoon, Saskatchewan, Canada; 2Department of Clinical Neurosciences, University of Calgary, Calgary, Alberta, CanadaAbstract: Gelastic seizures are epileptic events characterized by bouts of laughter. Laughter-like vocalization is usually combined with facial contraction in the form of a smile. Autonomic features such as flushing, tachycardia, and altered respiration are widely recognized. Conscious state may not be impaired, although this is often difficult to asses particularly in young children. Gelastic seizures have been associated classically to hypothalamic hamartomas, although different extrahypothalamic localizations have been described. Hypothalamic hamartomas are rare congenital lesions presenting with the classic triad of gelastic epilepsy, precocious puberty and developmental delay. The clinical course of patients with gelastic seizures associated with hypothalamic hamartomas is progressive, commencing with gelastic seizures in infancy, deteriorating into more complex seizure disorder resulting in intractable epilepsy. Electrophysiological, radiological, and pathophysiological studies have confirmed the intrinsic epileptogenicity of the hypothalamic hamartoma. Currently the most effective surgical approach is the trancallosal anterior interforniceal approach, however newer approaches including the endoscopic and other treatment such as radiosurgery and gamma knife have been used with success. This review focuses on the syndrome of gelastic seizures associated with hypothalamic hamartomas, but it also reviews other concepts such as status gelasticus and some aspects of gelastic seizures in other locations.Keywords: epilepsy, gelastic seizures, epilepsy surgery, hypothalamic hamartoma, intractable epilepsy

    2016-01-01

    Acute mitral regurgitation (MR) is a frequent complication of acute myocardial infarction, with a variable presentation depending on the severity of MR and the integrity of the subvalvular apparatus. While most cases are asymptomatic or have mild dyspnea, rupture of chordae tendinea or papillary muscles are catastrophic complications that may rapidly lead to cardiogenic shock and death. Despite the presence of pulmonary edema and/or cardiogrenic shock, the murmur of acute MR is usually subtle due to rapid equalization of left atrial and left ventricular pressure gradient, and therefore misleading. Echocardiog-raphy is the definite diagnostic modality, allowing quantification of the severity of MR and the structural abnormalities within the subvalvular apparatus. Severe MR accompa-nied by rupture of chordae or papillary muscles should be managed with temporary stabilization with medical treatment or with mechanical circulatory support, with sub-sequent surgical intervention to repair or replace the valve.

    Systemic antimicrobials are critically important in veterinary healthcare and resistance is a major concern. Antimicrobial stewardship will be important in maintaining clinical efficacy by reducing the development and spread of antimicrobial resistance. Bacterial skin infections are one of the most common reasons for using systemic antimicrobials in dogs and cats.Appropriate management of these infections is therefore crucial in any policy for responsible antimicrobial use. The goals of therapy are to confirm that an infection is present, identify the causative bacteria, select the most appropriate antimicrobial, ensure that the infection is treated correctly, and to identify and manage any underlying conditions. This is the first of two articles that will provide evidence-led guidelines to help practitioners address these issues. This article covers diagnosis, including descriptions of the different clinical presentations of surface, superficial and deep bacterial skin infections, how to perform and interpret cytology, and how to best use bacterial culture and sensitivity testing. The second article, to be published in a subsequent issue of Veterinary Record, will discuss therapy,including choice of drug and treatment regimens. PMID:23292951

    Full Text Available Nocardia spp are gram-positive, aerobic, acid-fast bacteria which exist as saprophytes in nature. Invasive disseminated infections are particularly common in immunocompromised or debilitated hosts. Superficial infections with Nocardia spp occur as a result of local trauma and contamination of the wound. Clinically, it presents as acute infection (abscesses or cellulitis, mycetoma, or sporotrichoid infection. Differential diagnosis includes eumycetoma, chromomycosis, blastomycosis, coccidioidomycosis, sporotrichosis, tuberculosis, botryomycosis, syphilis, yaws, and neoplasia. Its diagnosis is confirmed by demonstrating the causative organism in exudates (as granules, tissue specimens, or cultures. Early diagnosis will obviate need for drastic surgical measures as early institution of chemotherapy is effective in most patients. However, its diagnosis is often delayed due to diverse clinical presentations and for want of clinical suspicion, particularly in non-endemic areas. This paper presents 4 clinical forms of this not so uncommon disease, emphasizing the importance of high index of clinical suspicion, especially in non-endemic regions; and the significance of repeated examination of exudates for Nocardia granules for an early diagnosis.

    Nascimento, Osvaldo J M

    2013-09-01

    Leprosy is a chronic infectious peripheral neuropathy caused by Mycobacterium leprae. The different clinical presentations of the disease are determined by the quality of the host immune response. Early detection of leprosy and treatment by multidrug therapy are the most important steps in preventing deformity and disability. Thus the early recognition of the clinical leprosy presentation is essential. Mononeuritis, mononeuritis multiplex (MM), polyneuritis (MM summation) are the most frequent. The frequent anesthetic skin lesions are absent in the pure neuritic leprosy presentation form. Isolated peripheral nerve involvement is common, including the cranial ones. Arthritic presentation is occasionally seen, usually misdiagnosed as rheumatoid arthritis. Attention should be given to autonomic dysfunctions in leprosy. There are clinical presentations with severe neuropathic pain - painful small-fiber neuropathy. Leprous late-onset neuropathy (LLON) clinical presentation should be considered facing a patient who develop an inflammatory neuropathy many years after a previous skin leprosy treatment.

    We performed a retrospective review of medical records for 574 eastern box turtles (Terrapene carolina carolina) that presented to the University of Tennessee College of Veterinary Medicine (UTCVM) wildlife clinic between 1995 and 2007. These cases were reviewed to document and investigate the presenting complaints, as identified by a good Samaritan, final diagnoses, treatment modalities, days in hospital, and final disposition. Presenting complaints were consistent with the final diagnoses in 81% of cases. Trauma was both the most common presentation and final diagnosis. Associations between final diagnosis and either environmental temperature or precipitation were not significant (P>0.05). However, precipitation had a statistically significant positive association (P<0.05) with aural abscessation. Approximately 5% (28/574) of the box turtles were evaluated for packed cell volume total protein and white blood cell count. No differences were observed between sick and healthy animals for any of these variables. Multiple treatment modalities were used in these cases and were often used in combination, rather than as individual therapies. The number of days spent in the hospital ranged from 0 to 66 days, with a median of 2 days. The wildlife clinic of UTCVM should continue to evaluate the health status of eastern box turtles. Our findings indicate that the high caseload, as well as case variety of eastern box turtles in eastern Tennessee, suggests potential use as a biomonitor for this species. PMID:20966259

    Although previously considered a disorder of childhood, studies in the last decade have demonstrated that attention-deficit hyperactivity disorder (ADHD) continues to impair function into adulthood and responds to pharmacotherapy. Due to age-specific changes in roles and challenges, it is possible that presentation and response to intervention may differ between older and younger adults. A literature search for papers that identified older adults with ADHD, including papers describing its epidemiology, manifestation, and treatment, was the basis for this paper. There is a paucity of data on ADHD in older adults; however, small observational studies have characterized the presence, impact, and treatment of ADHD in adults over the age of 50 years, and larger epidemiologic studies have demonstrated that ADHD symptoms exist in older adulthood. Optimal criteria for diagnosis of ADHD and methods of treating ADHD in older individuals have not been systematically explored. In light of the limited data, this review discusses considerations for differential diagnosis and safe pharmacotherapy of ADHD in older adults. PMID:26659731

    Background. Tetanus is an acute disease caused by a neurotoxin produced by Clostridium tetani. Tetanus immunization has been available since the late 1930s but sporadic cases still occur, usually in incompletely vaccinated or unvaccinated individuals. Case Report. An elderly previously vaccinated female contracted tetanus following foot injury. Clinically she presented with meningitis causing diagnostic and therapeutic delays. Why Should Physician Be Aware of This? Even in developed countries the differential diagnosis of meningitis, especially in the elderly, should include tetanus. Treatment in intensive care unit is required. General population might benefit from vaccine boosters and education on this potentially fatal disease. PMID:25789186

    Systemic antimicrobials are critically important in veterinary healthcare, and resistance is a major concern. Antimicrobial stewardship will be important in maintaining clinical efficacy by reducing the development and spread of antimicrobial resistance. Bacterial skin infections are one of the most common reasons for using systemic antimicrobials in dogs and cats. Appropriate management of these infections is, therefore, crucial in any policy for responsible antimicrobial use. The goals of therapy are to confirm that an infection is present, identify the causative bacteria, select the most appropriate antimicrobial, ensure that the infection is treated correctly, and to identify and manage any underlying conditions. This is the first of two articles that will provide evidence-led guidelines to help practitioners address these issues. This article covers diagnosis, including descriptions of the different clinical presentations of surface, superficial and deep bacterial skin infections, how to perform and interpret cytology, and how to best use bacterial culture and sensitivity testing. Part 2 will discuss therapy, including choice of drug and treatment regimens. PMID:23292951

    Presentation of a cerebral aneurysm can be incidental, discovered at imaging obtained for unrelated causes, can occur in the occasion of imaging obtained for symptoms possibly or likely related to the presence of an unruptured aneurysm, or can occur with signs and symptoms at the time of aneurismal rupture. Most unruptured intracranial aneurysms are thought to be asymptomatic, or present with vague or non-specific symptoms like headache or dizziness. Isolated oculomotor nerve palsies, however, may typically indicate the presence of a posterior circulation aneurysm. Ruptured intracranial aneurysms are by far the most common cause of non-traumatic subarachnoid hemorrhage and represent a neurological emergency with potentially devastating consequences. Subarachnoid hemorrhage may be easily suspected in the presence of sudden and severe headache, vomiting, meningism signs, and/or altered mental status. However, failure to recognize milder and more ambiguous clinical pictures may result in a delayed or missed diagnosis. In this paper we will describe the clinical spectrum of unruptured and ruptured intracranial aneurysms by discussing both typical and uncommon clinical features emerging from the literature review. We will additionally provide the reader with descriptions of the underlying pathophysiologic mechanisms, and main diagnostic pitfalls.

Study Design: An observational study. Place and Duration of Study: Department of Pathology, Hayatabad Medical Complex (HMC), Peshawar, from January 2011 to May 2012. Methodology: A total of 618 bone marrow biopsy reports were reviewed. All biopsy reports labeled as acute leukemia were reviewed for age, gender, address, referring unit, diagnosis on bone marrow examination, presenting complaints, duration of illness and findings of clinical examination. Results: Ninety-two patients were diagnosed as suffering from acute leukemias (15%). ALL was most prevalent (46%), followed by AML (38%) and undifferentiated acute leukemia (16%). Males were affected more compared to females (60% vs. 40%). ALL and AML were predominant in pediatric (64%) and adults (77%) patients respectively. Patients from Afghanistan accounted for 33% of all cases followed by Peshawar (14%). Fever (77%), pallor (33%) and bleeding disorders (23%) were the main presenting complaints. Enlargement of liver, spleen and lymph nodes together was associated with ALL compared with AML (p = 0.004). Conclusion: ALL-L1 and AML-M4 were the most common sub-types. Fever, pallor and bleeding disorders were the main presenting complaints. Enlargement of liver, spleen and lymph nodes was more frequently associated with ALL compared to AML. (author)

    Objective: To determine the clinical preparation of primary hypothyroidism at the time of diagnosis. Design: It was an observational and prospective study. Place and Duration of Study: Civil Hospital, Karachi from 1st January 1997 to 31st December 1997. Subjects and Methods: Forty-eight consecutive cases of primary hypothyroidism were included. A detailed history with special emphasis on symptoms and signs was conducted and the findings observed were noted in previously made proforma. Results: Primary hypothyroidism was found to be 5 times more common in female patients, with male to female ratio 1:5, majority of cases (33.33%) were between 41 to 50 years of age. The common symptoms at the time of presentation were tiredness (95.8%), weakness (91.6%), weight gain (85.4%), hoarseness of voice (83.3%), cold intolerance (77.0%) and constipation (75.0%) in patients. Physical signs observed were delayed relaxation of ankle jerk (93.7%), periorbital edema (83.3%), thick tongue (62.5%), goiter (50.0%), dry and coarse skin (47.9%) in patients. Serum, TSH, T4 and T3 were performed in all cases through immunoradiometric technique. Serum TSH was markedly elevated, with normal to reduced T4 and T3 levels in all cases. Conclusion: Primary hypothyroidism was found more common in female than male of the age group 41-50 years. Weakness, tiredness, hoarseness of voice and constipation were the common symptoms noted. The diagnosis is almost certain on clinical grounds if the patient happens to have delayed relaxation of ankle jerks and periorbital puffiness. (author)

    The mode of presentation of coeliac disease has been changing to more atypical or silent disease. Few studies described the clinical presentation of adult coeliac disease in Ireland in recent years. We retrospectively collected the clinical data for all patients who had a diagnosis of coeliac disease made in our centre between January 07 and December 08. Forty seven adults, predominantly females (n = 30), had a confirmed diagnosis of coeliac disease made during the study period. In our patient cohort, the presenting symptom was diarrhoea in 19 (40%) patients, while 16 patients (34%) did not have any G.I. symptoms, 10 (21%) presented with anaemia. Females presented at a significantly younger age compared to males, with median ages at diagnosis of 44.5 and 57 years, respectively (p = 0.04). Females also presented more commonly with non G.I. symptoms (p = 0.07). The reasons behind this gender difference need further study.

    Full Text Available Abstract Background Urinary tract infection (UTI is common in children, and may cause serious illness and recurrent symptoms. However, obtaining a urine sample from young children in primary care is challenging and not feasible for large numbers. Evidence regarding the predictive value of symptoms, signs and urinalysis for UTI in young children is urgently needed to help primary care clinicians better identify children who should be investigated for UTI. This paper describes the protocol for the Diagnosis of Urinary Tract infection in Young children (DUTY study. The overall study aim is to derive and validate a cost-effective clinical algorithm for the diagnosis of UTI in children presenting to primary care acutely unwell. Methods/design DUTY is a multicentre, diagnostic and prospective observational study aiming to recruit at least 7,000 children aged before their fifth birthday, being assessed in primary care for any acute, non-traumatic, illness of ≤ 28 days duration. Urine samples will be obtained from eligible consented children, and data collected on medical history and presenting symptoms and signs. Urine samples will be dipstick tested in general practice and sent for microbiological analysis. All children with culture positive urines and a random sample of children with urine culture results in other, non-positive categories will be followed up to record symptom duration and healthcare resource use. A diagnostic algorithm will be constructed and validated and an economic evaluation conducted. The primary outcome will be a validated diagnostic algorithm using a reference standard of a pure/predominant growth of at least >103, but usually >105 CFU/mL of one, but no more than two uropathogens. We will use logistic regression to identify the clinical predictors (i.e. demographic, medical history, presenting signs and symptoms and urine dipstick analysis results most strongly associated with a positive urine culture result.

    Full Text Available Dementia is characterized by progressive decline in an alert individual, leading to loss of independence in day-to-day functioning. It is a generic term for a condition that has various causes and hence myriad clinical presentations. It has to be distinguished from age-related cognitive decline, depression and delirium all of which are common in the elderly population. Detailed history and mental status examination are necessary to identify dementia, fit it into one of the various bedside classifications and pursue the differential diagnosis. This teaching review summarizes current information on definition, differential diagnosis and classification of dementia and presents a brief elaboration of bedside cognitive testing pertaining to dementia. A bird′s eye view of the profiles of various dementia subtypes is also provided so that after reading this article the reader will able to recognize dementia, conduct clinical examination to identify the characteristic cognitive profile and formulate the differential diagnosis with confidence.

  19. Urological diagnosis using clinical PACS

    Mills, Stephen F.; Spetz, Kevin S.; Dwyer, Samuel J., III

    1995-05-01

    Urological diagnosis using fluoroscopy images has traditionally been performed using radiographic films. Images are generally acquired in conjunction with the application of a contrast agent, processed to create analog films, and inspected to ensure satisfactory image quality prior to being provided to a radiologist for reading. In the case of errors the entire process must be repeated. In addition, the radiologist must then often go to a particular reading room, possibly in a remote part of the healthcare facility, to read the images. The integration of digital fluoroscopy modalities with clinical PACS has the potential to significantly improve the urological diagnosis process by providing high-speed access to images at a variety of locations within a healthcare facility without costly film processing. The PACS additionally provides a cost-effective and reliable means of long-term storage and allows several medical users to simultaneously view the same images at different locations. The installation of a digital data interface between the existing clinically operational PACS at the University of Virginia Health Sciences Center and a digital urology fluoroscope is described. Preliminary user interviews that have been conducted to determine the clinical effectiveness of PACS workstations for urological diagnosis are discussed. The specific suitability of the workstation medium is discussed, as are overall advantages and disadvantages of the hardcopy and softcopy media in terms of efficiency, timeliness and cost. Throughput metrics and some specific parameters of gray-scale viewing stations and the expected system impacts resulting from the integration of a urology fluoroscope with PACS are also discussed.

    Full Text Available Peripartum cardiomyopathy (PPCM is a disorder which describes initial left ventricular dysfunction and symptoms of cardiac failure between the late stages of pregnancy and the first five months after delivery. PPCM is a difficult diagnosis to make because it resembles common cardiac issues that are normally experienced during pregnancy. Clinical presentation is representative of cardiac failure and is commonly misdiagnosed until further progression. This disorder is commonly seen in some regions of the world and rare in others. Proper evaluation and rapid treatment are crucial for an effective recovery. Subsequent pregnancies should be evaluated before pursuing. The purpose of this review article is to discuss the difficulties in clinical diagnosis and provide a concise and practical approach to treatment of suspected PPCM.

    2016-01-01

    Angioedema (AE) is a unique clinical presentation of an unchecked release of bradykinin. The origin of this clinical presentation can be either genetic or acquired. The outcome within the patient is subcutaneous swelling of the lower layers of the epidermis. Symptoms are most often localized to the upper airway or the gastrointestinal tract. A typical course resolves in 5 to 7 days, but in some patients, the clinical manifestations exist up to 6 weeks. Hereditary AE is rare and genetically linked, and typically, the patient has episodes for many years before diagnosis. Episodes of acquired AE may be drug induced, triggered by a specific allergen, or idiopathic. Angioedema can elicit the need for critical care interventions, for advanced airway management, or unnecessary abdominal surgery. The treatment for these patients is evolving as new pharmacological agents are developed. This article addresses subtypes of AE, triggers, pharmacology, and information for interdisciplinary team planning of individualized case management. PMID:27258954

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients. MATERIAL AND METHODS: A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years. Each subject was clinically examined, in the morning and in the afternoon, along 1 day. A focused anamnesis allowed identifying symptoms of hyposalivation, like xerostomia complaints (considered as a reference symptom, chewing difficulty, dysphagia and increased frequency of liquid intake. Afterwards, dryness of the mucosa of the cheecks and floor of the mouth, as well as salivary secretion during parotid gland stimulation were assessed during oral examination. RESULTS: Results obtained with Chi-square tests showed that 71 patients (48.9% presented xerostomia complaints, with a significant correlation with all hyposalivation symptoms (p <0.05. Furthermore, xerostomia was also significantly correlated with all data obtained during oral examination in both periods of evaluation (p<0.05. CONCLUSION: Clinical diagnosis of hyposalivation in hospitalized patients is feasible and can provide an immediate and appropriate therapy avoiding further problems and improving their quality of life.

    There are a number of clinical questions for which there are no easy answers, even for welltrained doctors. The diagnostic tool commonly used to assess cognitive impairment in neurodegenerative diseases is based on established clinical criteria. However, the differential diagnosis between disorders can be difficult, especially in early phases or atypical variants. This takes on particular importance when it is still possible to use an appropriate treatment. To solve this problem, physicians need to have access to an arsenal of diagnostic tests, such as neurofunctional imaging, that allow higher specificity in clinical assessment. However, the reliability of diagnostic tests may vary from one to the next, so the diagnostic validity of a given investigation must be estimated by comparing the results obtained from "true" criteria to the "gold standard" or reference test. While pathological analysis is considered to be the gold standard in a wide spectrum of diseases, it cannot be applied to neurological processes. Other approaches could provide solutions, including clinical patient follow-up, creation of a data bank or use of computer-aided diagnostic algorithms. In this article, we discuss the development of different methodological procedures related to analysis of diagnostic validity and present an example from our own experience based on the use of I-123-ioflupane-SPECT in the study of patients with movement disorders. The aim of this chapter is to approach the problem of diagnosis from the point of view of the clinician, taking into account specific aspects of neurodegenerative disease. PMID:26567736

    Hypogonadotropic patients may visit pediatricians, general practitioners, endocrinologists or urologists, presenting with microphallus, cryptochidism or pubertas tarda and delayed bone maturation. Congenital hypogonadotropic hypogonadism is characterized, apart from small testes, by the constellation of low serum levels of testosterone, LH and FSH. Kallman's syndrome is characterized by congenital hypogonadotropic hypogonadism with midline defects such as anosmia (a deficiency of the sense of smell). The first case report dates back to 1856, and genetic defects causing the syndrome have been recently described. The diagnosis can be clinically suspected and is established by confirming hormonal studies. PMID:11052640

    Background: Tuberculosis (TB) remains a worldwide problem. Intestinal TB (ITB) constitutes a major public health problem in developing countries and has been associated with significant morbidity and mortality. The aim of this study was to characterize the clinical, radiological, endoscopic, and pathological features of ITB and to define the strategy for establishing the diagnosis. Methods: A retrospective study (from January 2000 to June 2015) was carried out in Peking Union Medical College Hospital and all hospitalized cases were diagnosed as ITB during the study period were included. The relevant clinical information, laboratory results, microbiological, and radiological investigations were recorded. Results: Of the 85 cases, 61 cases (71.8%) were ranged from 20 to 50 years. The ileocecal region was involved in about 83.5% (71/85) of patients. About 41.2% (35/85) of patients had co-existing extra ITB, especially active pulmonary TB. Abdominal pain (82.4%) was the most common presenting symptom followed by weight loss (72.9%) and fever (64.7%). Both T-cell spot of TB test (T-SPOT.TB) and purified protein derivatives (PPD) tests were performed in 26 patients: 20 (76.9%) positive T-SPOT.TB and 13 (50.0%) positive PPD were detected, with a statistical significant difference (P = 0.046). Twenty cases (23.5%) were histopathology and/or pathogen confirmed TB; 27 cases (31.8%) were diagnosed by clinical manifestation consistent with ITB and evidence of active extra ITB; 38 cases (44.7%) were diagnosed by good response to diagnostic anti-TB therapy. Conclusions: ITB is difficult to diagnose even with modern medical techniques due to its nonspecific clinical and laboratory features. At present, combination of clinical, endoscopic, radiological, and pathological features continues to be the key to the diagnosis of ITB. PMID:27231171

    Food allergies are immune-mediated responses to food proteins. Because of differences in the underlying immunologic mechanisms, there are varying clinical presentations of food allergy. This article discusses the manifestations of IgE-mediated disorders, including urticaria and angioedema, rhinoconjunctivitis, asthma, gastrointestinal anaphylaxis, generalized anaphylaxis, food-dependent exercise-induced anaphylaxis, and oral allergy syndrome. It also reviews the presentations of mixed IgE- and cell-mediated disorders, including atopic dermatitis and eosinophilic gastrointestinal disorders. Finally, the manifestations of cell-mediated food allergies are discussed, including dietary protein-induced proctitis and proctocolitis, food protein-induced enterocolitis syndrome, celiac disease, and food-induced pulmonary hemosiderosis.

    Full Text Available INTRODUCTION: This article deals with the description and diagnosis of a new nosographic syndrome, which received the eponym of "Cugini's syndrome" by the name of the Author who discovered its clinical picture. This syndrome is characterized by the binomial: "minimal target organ damage associated to monitoring prehypertension". CLINICAL HISTORY AND DIAGNOSIS: Between the years 1997 and 2002, the Author published a series of investigations regarding some office normotensives who inexplicably showed incipient signs of target organ damage (TOD. Investigated via ambulatory (A blood (B pressure (P monitoring (M, these subjects were surprisingly found not to be hypertensive. Neverthless, the office normotensives with TOD exibited the daily mean level of their systolic (S and diastolic (D BP (DML SBP/DBP significantly more elevated as compared to true normotensives. Because of these ABPM findings, the Author realized that the investigated subjects were false normotensives whose TOD was associated with a monitoring prehypertension (ABPM-diagnosable prehypertension alias monitoring prehypertension alias masked prehypertension. The year after the last Cugini's investigation, the INC-7 Reports introduced the term: "prehypertension" in its classification of arterial hypertension, as an office sphygmomanometric condition in between office normotension and office hypertension. The ABPM cut-off upper limits for a differential diagnosis between monitoring normotension, prehypertension and hypertension are reported, as calculated by the Author in its collection of ABPMs. The eponym of "Cugini's syndrome" was assigned in 2007 and confirmed in 2009. CONCLUSIVE REMARKS: The monitoring prehypertension is a further condition of discrepancy between office sphygmomanometry and ABPM, as per a masked prehypertension, whose diagnosis has to be immediately diagnosed, for preventing the onset of a TOD. There are reported the present investigations dealing with the possible

    2016-05-01

    Metal implant sensitivity (intolerance) can cause pain, reduced mobility, loosening of the implant and skin rashes. Knowledge of differential diagnoses, histology and appropriate diagnostics are essential for proper diagnosis. To outline typical clinical signs and histology in metal-implant-associated skin lesions we present three exemplary patients from our implant allergy outpatient department and give an overview of the current literature regarding metal implant sensitivity. In patients with a negative patch test the lymphocyte transformation test may reveal metal sensitization. Even "pure" titanium alloys may contain traces of nickel. The histology of implant-associated skin reactions goes from teleangiectatic postimplantation erythema to eczema and vasculitis. Based on the synopsis of history, clinical picture, allergological testing and histology, metal implant sensitivity can be diagnosed more precisely. PMID:27090521

    The purpose of the present study was to evaluate the role of diagnostic tools and management options for patients with pyogenic sacroiliitis, including potential complications. This retrospective study included 16 patients with pyogenic sacroiliitis who were admitted to a single orthopaedic centre between 2007 and 2012. The following data were collected: demographics, history, radiography, magnetic resonance images (MRI), biological data, type of pathogenic agent, abscess formation, type of management, and clinical outcome. Our study demonstrated that only one-fifth of the patients with lumbogluteal or hip pain had established diagnoses of suspected pyogenic sacroiliitis upon admission. MRIs confirmed this diagnosis in all cases. MRI examinations revealed joint fluid in the sacroiliac joint and significant oedema of the adjacent bone and soft tissues. In 12 of the 16 cases, erosions of the subchondral bone were encountered. Contrast-enhanced MRI revealed that 9 patients had abscesses. All patients received antibiotic therapy. Antibiotic treatment was only successful in 9 cases. The other 7 patients underwent computed tomography (CT)-guided abscess drainage. Drainage was sufficient for 4 patients, but 3 patients required open surgery. One patient required sacroiliac arthrodesis. The clinical outcomes included minimal disability (n = 10), moderate disability (n = 5), and full disability (n = 1) of the spine. Contrast-enhanced MRI is mandatory for a reliable diagnosis. Abscess formation was observed in approximately half of the MRI-diagnosed sacroiliitis cases and required minimally invasive drainage under CT guidance or frequently open surgery. (orig.)

  15. Clinical presentation in patients with systemic sclerosis

    International Nuclear Information System (INIS)

    Introduction: systemic sclerosis is an autoimmune disease characterized by endothelial damage, and skin, vessel and internal organ fibrosis and inflammation. There are differences in terms of frequency, severity and prognosis for the different ethnic groups, what reinforces the importance of the study in each geographical region with the purpose of enabling early diagnosis of its incipient symptoms.Methods: we conducted a descriptive and retrospective study form March 2006 through March 2008, including patients with a final diagnosis of systemic sclerosis, who are treated at the Systemic Autoimmune Diseases Unit at the Clinicas Hospital. Results: 31 women were included in the study, average follow-up of patients was 39.2 months, and average age at the time of diagnosis was 47.6 years. Eleven patients (35,5) presented diffuse disease and 20 (64.5) of them evidenced limited disease. Thirty patients presented Raynaud's phenomenon. In 92 of cases capilaroscopy showed a sclerodermiform pattern. In terms of the respiratory system, we found interstitial pathology in 25 of cases, pulmonary arterial hypertension in 22.2 and are restrictive pattern in respiratory function studies in 35.5. Also, 67.7 presented digestive manifestations and 9.6 developed sclerodermic renal crisis. We found anti-nuclear antibodies (ANA) in 29 out of 31 patients (93,5) patients; 16 presented anticentromere antibodies and five anti-topoisomerasa-I antibodies. The four patients (12.9)who died during follow-up presented common elements such as diffuse sclerosis, digital ulcers and severe respiratory compromise. Conclusions: the clinical and immune characteristics found in our study were similar to those described in other series. Should there be no specific treatment, it is essential to perform regular assessment of visceral impact in order to control and delay complications which result in high morbimortality rates.

  17. Clinical or radiological diagnosis of impingement

    International Nuclear Information System (INIS)

    Shoulder impingement syndrome is a clinically common entity involving trapping of tendons or bursa with typical clinical findings. Important radiological procedures are ultrasound, magnetic resonance imaging (MRI) and MR arthrography. Projection radiography and computed tomography (CT) are ideal to identify bony changes and CT arthrography also serves as an alternative method in cases of contraindications for MRI. These modalities support the clinically suspected diagnosis of impingement syndrome and may identify its cause in primary diagnosis. In addition, effects of impingement are determined by imaging. Therapy decisions are based on a synopsis of radiological and clinical findings. The sensitivity and specificity of these imaging modalities with regard to the diagnostics of a clinically evident impingement syndrome are given in this review article. Orthopedic and trauma surgeons express the suspicion of an impingement syndrome based on patient history and physical examination and radiologists confirm structural changes and damage of intra-articular structures using dedicated imaging techniques.

    Symptomatic gastroesophageal reflux occurs daily in an estimated 7% of adults and weekly or monthly in 29%. Untreated it can lead to esophageal erosions, ulceration and stricture formation. The pathogenesis is often multifactorial: defects in the function of the lower esophageal sphincter, esophageal clearance mechanisms and gastric emptying combine to produce frequent lengthy periods during which the lower esophagus is bathed in regurgitated acid. In most patients reflux disease is easily re...

    Full Text Available Glucosamine sulfate or hydrochloride and chondroitin sulfate belong to the natural components of cartilage intercellular substance. In osteoarthrosis, they exert a pronounced symptom-modifying effect and, when used long, are also able to suppress the X-ray progression of the disease. Multi-ingredient medications containing glucosamine and chondroitin have benefits over each of them when used alone. These drugs include teraflex. The efficacy of pharmacological agents appears to be associated not so much with the stimulation of cartilage matrix synthesis as with their anti-inflammatory properties.

  3. CT diagnosis of appendicitis with atypical clinical features

    International Nuclear Information System (INIS)

    Objective: To investigate the value of CT in diagnosis of appendicitis with atypical clinical features. Methods: CT manifestations of 20 cases of appendicitis, which were not initially considered on clinical presentation, confirmed surgically and pathologically were retrospectively analyzed. Results: The CT findings of appendicitis included: (1) The appendix enlarged in diameter, with wall thickening and enhancement after administration of IV contrast material (7 cases), presence of appendicolith in 4 cases. (2) pericecal inflammation (14 cases). (3) Localized abscess of right lower quadrant (11 cases), calcified appendicolith seen in 2 cases. CT misdiagnosed 2 cases as tumour of ascending colon, and another 2 cases as pelvic inflammatory disease. Conclusions: The clinical diagnosis of appendicitis is very difficult when patients present with atypical signs and symptoms, but in most cases, the correct diagnosis of appendicitis could be made on the basis of CT findings

    Full Text Available Background: Ample use of serological markers of high sensitivity and specificity led to relevant changes in the epidemiology of celiac disease. The impact of these changes in our country is poorly known. Aim: To assess the diagnostic procedures, clinical presentations and follow up of celiac disease as conducted in current pediatric practice. Material and methods: A multicentric retrospective study of patients diagnosed between 2000 and 2005 in five pediatric hospitals in Santiago, Chile. Data was obtained from clinical records, recorded in electronic spreadsheets and analyzed by descriptive statistics. Results: Seventy four of 83 identified patients fulfilled the inclusion criteria and were analyzed. Mean time to reach the diagnosis was 2.1 years. Cases younger than 10 years presented digestive manifestations such as chronic diarrhea and abdominal distension. Twenty one percent of older patients had atypical presentations (mainly short stature, refractory anaemia. Ten percent of cases were screened because a first degree relative had celiac disease. All patients had significant duodenal/jejunal lesion. IgA-antiendomysial antibodies (n =65 and IgA-antigliadin antibodies (n =23 were the most commonly used screening tests used but often, they were not available for follow up. A second biopsy was planned in all patients but only 26 had it due to repeated dietary transgressions, often due to unnoticed consumption of gluten in poorly labeled products. Conclusions: Digestive manifestations were the main presentation form for celiac disease among patients under 10 years of age. Atypical symptoms become relevant in patients older than 10 years. Antiendomysial and antitransglutaminase antibody measurement should be incorporated for routine screening and follow up of celiac disease in public hospitals. To improve food labeling about their gluten content is needed

    2016-07-01

    In the present chapter the authors present a brief overview of the diagnostic methods proposed over time for Hodgkin lymphoma (HL) spread detection, moving from surgical procedures, through standard radiological and functional imaging techniques to the present state of the art for HL staging. The main body of the review will be dedicated to the recently published guidelines for lymphoma staging (including HL) agreed by the experts during the 12th International Congress for Malignant Lymphoma in Lugano. The recommendations of the panel on how to integrate flurodeoxyglucose positron emission tomography (FDG-PET) scan in the armamentarium of staging procedures will be presented and commented, with a special emphasis on the utility of special procedures, such as bone marrow trephine biopsy, which is deemed no longer needed in the PET era. While the HL diagnosis is straightforward in most cases, sometimes HL is a subtle disease, difficult to diagnose for the paucity of symptoms, the absence of physical findings, or for concomitant immunologic disorders: a compete overview of the common and rare patterns of HL clinical presentation will be also offered. The future perspective of PET scan use will be based on a operator-independent, quantitative readings of the scan thanks to a plethora of sophisticated dedicated software, which are now available, able to quantify every voxel captured by the tumor to display the metabolically active tumor volume. Moreover, new tracers are now available able to track the new pathways of cellular metabolism beside glycolysis such as amino acids or purine-analogues or specific oncoproteins; the preliminary, promising results will be reported. Preliminary results from other imaging techniques, such as diffusion-weighted magnetic resonance (DW-MRI) will be also reported. PMID:27496305

  9. Chronic diarrhea. Diagnosis and clinical evaluation

    International Nuclear Information System (INIS)

    Chronic diarrhea is a syndrome of great clinical complexity, which is frequently encountered by general physicians, internists and gastroenterologists. Differential diagnosis is very broad and sometime finding the precise cause can be difficult, expensive and frustration. Literature published about this topic lack, in general, adequate controlled studies and for this reason recommendations for diagnostic evaluation and treatment are based upon series of cases, experience of the institutions or expert opinion and not on reasonable evidence. On the other hand, many of the classical diagnostic tests that have survived until now were designed over physiologic foundations and have not been validated extensively with the precision of a clinical test. This limits its acceptance, application and standardization in the daily practice. There is not a general agreement about diagnosis and treatment of chronic diarrhea and many of the experts divert recommendation about their recommendations. The purpose of this paper is to define some general guidelines about the clinical evaluation of patients with chronic diarrhea that lead us to a rational approach based upon clinical trials and the appropriate use of the many different tests

    Diagnosis of colonic duplication can pose a potential problem even for those familiar with gastro-intestinal tract duplications in general but unaware of the condition due to its rarity and its apparently bimodal clinical presentation. In this report of five cases of surgically proven pediatric colonic duplication, we illustrate how the condition manifests clinically and describe the imaging features in an attempt to illustrate this bimodal presentation of the condition. The possible etiology, associated congenital anomalies and modes of clinical presentation are reviewed based on literature review as well as on our own experience.

    Although the concept of united airway disease has been widely accepted, most scholars emphasize only the effect of rhino-sinusitis while ignoring the pharyngeal factors to the lower airway, especially to the allergic pharyngitis (AP), which still lacks enough awareness. First of all, absence of unified diagnostic standard leads to the lack of epidemiological data, which, results in doctors' personal experience but no guideline in treatments. In addition, it is still not clear that the role of AP in the allergic airway diseases and its relationship with asthma. However, the number of patients with AP has been increasing obviously in daily clinic practice. Combined with the previous observation, this paper does a systematic review about the clinical problems of AP, expecting to give a hand to the clinical diagnosis and treatment of AP. PMID:26685417

  14. Clinical diagnosis of malignant pleural mesothelioma

    International Nuclear Information System (INIS)

    We evaluated clinical and thoracoscopic findings of cases that underwent thoracoscopic biopsy for the diagnosis of malignant pleural mesothelioma. We reviewed 32 cases suspected of having malignant pleural mesothelioma from 2003 to 2006. We made a diagnosis of malignant pleural mesothelioma via thoracoscopic biopsy (19 cases). The cut-off level of hyaluronic acid in malignant effusions, selected on the basis of the best diagnostic efficacy, was 100 μg/ml. We can decrease the incidence of false negative cases by the combination of CT findings and the presence of hyaluronic acid in pleural effusion. In the pleural thickening type of thoracoscopic appearance, the parietal pleurae were thickened, and small nodules were rare. As for this type, tumor cells were histologically absent or confined to the submesothelial tissue. We considered that determinations of specific sites were difficult. Adequate tissue samples obtained via video-assisted thoracoscopy were necessary for diagnosis. We can decrease the incidence of false negative cases by the combination of the presence of hyaluronic acid in pleural effusion and thoracoscopic biopsy. (author)

    Objective To investigate the final diagnosis of patients with unexplained dysphagia and the clinical and laboratory findings supporting the diagnosis. Methods We retrospectively analyzed 143 patients with dysphagia of unclear etiology who underwent a videofluoroscopic swallowing study (VFSS). The medical records were reviewed, and patients with a previous history of diseases that could affect swallowing were categorized into a missed group. The remaining patients were divided into an abnormal or normal VFSS group based on the VFSS findings. The clinical course and final diagnosis of each patient were examined. Results Among the 143 patients, 62 (43%) had a previous history of diseases that could affect swallowing. Of the remaining 81 patients, 58 (72.5%) had normal VFSS findings and 23 (27.5%) had abnormal VFSS findings. A clear cause of dysphagia was not identified in 9 of the 23 patients. In patients in whom a cause was determined, myopathy was the most common cause (n=6), followed by laryngeal neuropathy (n=4) and drug-induced dysphagia (n=3). The mean ages of the patients in the normal and abnormal VFSS groups differed significantly (62.52±15.00 vs. 76.83±10.24 years, respectively; p<0.001 by Student t-test). Conclusion Careful history taking and physical examination are the most important approaches for evaluating patients with unexplained swallowing difficulty. Even if VFSS findings are normal in the pharyngeal phase, some patients may need additional examinations. Electrodiagnostic studies and laboratory tests should be considered for patients with abnormal VFSS findings. PMID:26949675

    Full Text Available Introdution: Tuberculosis (TB, with different types of respiratory tract involvements, has a high rate of mortality all around the world. Endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. Aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed and delayed treatment. High suspicious needs to diagnose and may be need bronchoscopy for confirmed the diagnosis. It can be associated with sever complication and early diagnosis and treatment are necessary for prevention of adverse effect.   Materials and Methods: This retrospective study was conducted in a teaching hospital during 2005-2010. Patients diagnosed with endobronchial tuberculosis through bronchoscopic biopsy were included in the study. Diagnosis was confirmed by observation of caseous necrosis, bronchial lavage fluid or positive acid-fast staining in tissue samples obtained through bronchial biopsy. Moreover, demographic information, endobronchial view, lab tests, as well as clinical and radiographic findings were reviewed and evaluated retrospectively. Results: A total of 20 cases were confirmed with endobronchial tuberculosis, 75% of whom were female with the mean age of 60 years. The results showed that the most common clinical symptom was cough (80%, the most common finding in the chest X-ray was consolidation (75%, and the most common bronchoscopic feature was anthracosis (55%. Conclusion: TB is still a major concern, particularly in the developing countries. Thus, in order for early diagnosis and prevention of this disease, we need to pay meticulous attention to its clinical manifestations and bronchoscopic features.

    2006-01-01

    Full Text Available Melioidosis is an emerging infection in Brazil and neighbouring South American countries. The wide range of clinical presentations include severe community-acquired pneumonia, septicaemia, central nervous system infection and less severe soft tissue infection. Diagnosis depends heavily on the clinical microbiology laboratory for culture. Burkholderia pseudomallei, the bacterial cause of melioidosis, is easily cultured from blood, sputum and other clinical samples. However, B. pseudomallei can be difficult to identify reliably, and can be confused with closely related bacteria, some of which may be dismissed as insignificant culture contaminants. Serological tests can help to support a diagnosis of melioidosis, but by themselves do not provide a definitive diagnosis. The use of a laboratory discovery pathway can help reduce the risk of missing atypical B. pseudomallei isolates. Recommended antibiotic treatment for severe infection is either intravenous Ceftazidime or Meropenem for several weeks, followed by up to 20 weeks oral treatment with a combination of trimethoprim-sulphamethoxazole and doxycycline. Consistent use of diagnostic microbiology to confirm the diagnosis, and rigorous treatment of severe infection with the correct antibiotics in two stages; acute and eradication, will contribute to a reduction in mortality from melioidosis.

  1. Clinical findings in 16 patients with tomographic diagnosis of schizencephaly

    International Nuclear Information System (INIS)

    Objective: to establish a correlation between clinical features in a group of children with tomographic diagnosis of schizencephaly and clefts extent and localization. Materials and methods: retrospective study of dossiers from the archives of Neurology and Medical Genetics Services at Instituto Fernandes Figueira/FIOCRUZ and Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2000 and 2003. The study included 16 patients, nine female and seven male, with tomographic diagnosis of schizencephaly investigated for clinical findings, psychomotor development, motor/cognitive deficits and epilepsy. Results: predominance of bilateral clefts in 10:16 patients, open-lip schizencephaly type in 23:27 patients, and small lips in 11:27 patients. As regards anomalies associated with schizencephaly, pellucid septum absence was the most frequent one (10:16 patients). As regards clinical findings, 15 patients presented with developmental delay and motor deficit, six patients with cognitive deficit and ten with epilepsy. In three patients, we observed discordant clinical findings and cleft sizes, although the clefts were small, the clinical features severity was high because of other cerebral anomalies. Conclusion: the clinical features of schizencephaly are related to the size of the clefts, regardless laterality, presenting higher severity when associated with other cerebral anomalies. (author)

    Multiple myeloma is a systemic B-cell lymphoproliferative disease with varied manifestations. Its diagnosis can therefore pose difficulties for both the clinicians and pathologists. Jaw lesions, though not uncommon, rarely present as the first sign in multiple myeloma. We present here the case of a 45 year-old female who presented with a swelling of the jaw and on subsequent work-up, was diagnosed with multiple myeloma. Recent research regarding this disease has also been highlighted.

    Twenty-one pregnancies with sonographic evidence of subchorionic hemorrhage were evaluated clinically and sonographically. Clinical evaluation included maternal age, gravidity, parity, gestational age, presence of pain, presence and amount of bleeding, and pregnancy outcome. Sonographic evaluation included the relative and absolute size of the hematoma, its echogenicity and location in relation to the placenta, the presence of marginal placental abruption, and progress on follow-up examinations. The outcome of these pregnancies was unfavorable in 15 cases (71%) and correlated well with the relative and absolute size of the hematoma, severity of vaginal bleeding, change in hematoma size on follow-up examination, and presence of pain. There was no significant correlation between the outcome and the echogenicity of the hematoma, presence of placental margin elevation, gestational and maternal age, gravidity, or parity. All hematomas extended to the margin of the placenta. Subchorionic hemorrhage is a frequent cause of first and second trimester bleeding and has a grave prognosis. Familiarity with the varied sonographic appearances and meticulous sonographic examination with special attention to the placental margins can be helpful in the diagnosis. PMID:3307354

  7. Mushroom poisoning in children: clinical presentation and outcome

    International Nuclear Information System (INIS)

    A variable clinical picture characterizes mushroom poisoning. The Amatoxin, the main toxic component of these fungi, are responsible for gastrointestinal symptoms as well as hepatic and renal failure. As acute gastroenteritis is extremely common in our set up, so every patient presenting with these symptoms is treated as gastroenteritis of viral aetiology. The authors present the clinical picture of the phalloid syndrome, its treatment and immediate outcome. All children age less than 16 years admitted in Saidu Hospital Swat from January to December 2006 with mushroom poisoning were included in the study. Patients with doubtful history or with associated illness were not included. The diagnosis was based on the clinical picture of the patient, history and the laboratory data. In addition to maintenance of fluid and electrolyte balance and treating sepsis, oral Silymarin and intravenous penicillin was started. Liver function tests, renal functions tests, serum electrolytes and coagulation profile was done in all the patients. The severity of poisoning was graded according to hepatic transaminase elevations and prolongation of prothrombin time. Of the 18 patients, fifteen were above five years of age. Female were twice in number. Fifteen patients developed hepatic failure and three patients developed renal failure. Thirteen patients expired. To start timely management, Mushroom poisoning should be considered in the differential diagnosis in patients presenting with food poisoning particularly coming in groups. Delay in diagnosis is associated with high mortality. (author)

    Full Text Available OBJECTIVE: To describe the clinical presentation a group of patients with juvenile onset of Huntington disease. METHOD: All patients were interviewed following a structured clinical questioner. Patients were genotyped for the trinucleotide cytosine-adenine-guanine (CAG repeat in the Huntington Disease gene. High resolution brain MRI was performed in all patients. RESULTS: We identified 4 patients with juvenile onset of disease among 50 patients with Huntington disease followed prospectively in our Neurogenetics clinic. Age at onset varied from 3 to 13 years, there were 2 boys, and 3 patients had a paternal inheritance of the disease. Expanded Huntington disease allele sizes varied from 41 to 69 trinucleotide repeats. The early onset patients presented with rigidity, bradykinesia, dystonia, dysarthria, seizures and ataxia. MRI showed severe volume loss of caudate and putamen nuclei (p=0.001 and reduced cerebral and cerebellum volumes (p=0.01. CONCLUSION: 8% of Huntington disease patients seen in our clinic had juvenile onset of the disease. They did not present with typical chorea as seen in adult onset Huntington disease. There was a predominance of rigidity and bradykinesia. Two other important clinical features were seizures and ataxia, which related with the imaging findings of early cortical atrophy and cerebellum volume loss.

Here we present an audit of cases presenting to a rhinology clinic over a two-year period, as well as an overview of the relevant embryology and different clinical presentations of nasopharyngeal bursitis. For 2008–2009, six patients were diagnosed to have nasopharyngeal bursitis, including four males and two females, of mean age 54 years. Two distinct pathologic types were observed, comprising three patients with classical Tornwaldt’s cyst and three with crust-type bursitis. This audit highlights the importance of recognition of the crust-type of nasopharyngeal bursitis and its anatomic and clinical features. A combined endonasal and transoral endoscopic approach is a minimally invasive procedure and an effective method of treating both types of the disease. Our findings are discussed in relation to the embryology of the disorder, with a clinical emphasis on crust-type nasopharyngeal bursitis.Keywords: nasopharyngeal bursitis, crust type, Tornwaldt’s cyst, endoscopic disruption

    Full Text Available [u][/u] Narcolepsy is a chronic hypersomnia characterized by excessive daytime sleepiness (EDS and manifestations of disrupted rapid eye movement sleep stage (cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. Mechanisms underlying narcolepsy are not fully understood. Experimental data indicate that the disease is caused by a loss of hypocretin neurons in the hypothalamus, likely due to an autoimmune process triggered by environmental factors in susceptible individuals. Most patients with narcolepsy and cataplexy have very low hypocretin-1 levels in the cerebrospinal fluid. An appropriate clinical history, polysomnogram, and multiple sleep latency test are necessary for diagnosis of the disease. Additionally, two biological markers, i.e., cerebrospinal fluid hypocretin-1 levels and expression of the DQB1*0602 gene, are used. The treatment of narcolepsy is aimed at the different symptoms that the patient manifests. Excessive daytime sleepiness is treated with psychostimulants (amphetamine-like, modafinil and armodafinil. Cataplexy is treated with sodium oxybate (GHB, tricyclic antidepressants, or selective serotonin and noradrenaline reuptake inhibitors. Sleep paralysis, hallucinations, and fragmented sleep may be treated with sodium oxybate. Patients with narcolepsy should follow proper sleep hygiene and avoid strong emotions.

    Full Text Available Gingival melanoacanthoma is a rare, benign pigmented lesion characterized clinically by sudden onset and rapid growth of a macular brown black lesion and histologically by acanthosis of superficial epithelium and proliferation of dendritic melanocytes. This article reports a previously undescribed case of pigmented unilateral diffuse gingival enlargement, which on histopathological examination proved to be melanoacanthoma. Intraoral examination revealed pigmented unilateral diffuse gingival enlargement in relation to second and third quadrants buccally, palatally/lingually. Based on these clinical findings, gingivectomy was performed and the excised tissue was sent for biopsy. Microscopic examination revealed acanthotic and parakeratotic surface epithelium with dendritic melanocytes distributed in basal and suprabasal layers of the epithelium. 1 year follow-up recall revealed no recurrence of lesion at the surgical sites. Our patient exhibits an unusual clinical presentation of melanoacanthoma of gingiva. Pigmented gingival overgrowth of recent origin and without any etiologic factors warrants histopathologic examination.

    To determine the prevalence and associated clinical symptoms of pes anserine bursitis in symptomatic adult knees. A retrospective review was performed of the reports of 509 knee MRI studies obtained from July 1998 to June 2004 on 488 patients presenting to an orthopaedic clinic with knee pain suspected to be due to internal derangement. The MRI studies and case histories of all patients reported to have pes anserine bursitis were reviewed. The management of these patients was also noted. The prevalence of pes anserine bursitis as detected on MRI is 2.5%. The commonest clinical presentation was pain along the medial joint line mimicking a medial meniscal tear. We suggest that an accurate diagnosis of pes anserine bursitis on MRI will help prevent unnecessary arthroscopy and possibly initiate early treatment of the condition. Axial imaging is important in these cases to differentiate the bursa from other medial fluid collections. (orig.)

    Full Text Available Parasomnias, as described in the recent second edition of the International Classification of Sleep Disorders, are “undesirable physical events or experiences” occurring during sleep transition, during arousal from sleep, or within the sleep period. These events encompass abnormal sleep related movements, behaviors, emotions, perceptions, dreaming, and autonomic nervous system functioning. Parasomnias are classified as: 1 disorders of arousal (from non-rapid eye movement, or NREM, sleep; 2 parasomnias usually associated with REM (rapid eye movement sleep; and 3 other parasomnias. This sleep disorders in childhood are common, and often more frequent than in adults. Clinicians should be aware that many pediatric parasomnias have benign and self-limited nature. Most of the parasomnias may not persist into late childhood or adolescence. Parasomnias in adults often differ in type from childhood parasomnias and may portend significant psychiatric disturbances or neurodegenerative disorders. A reliable diagnosis can often be made from a detailed history from the patient and, if possible, the parents or bed partner. Detailed overnight investigations of parasomnias are usually not required. The non-REM parasomnias are more common in community although REM parasomnias are more likely to be seen in general neurological practice. Sleep related eating disorder, sleep related dissociative disorders and sleep related sexual behavior and sleep related violence are novel and rarely reported sleep disorders. REM sleep behavior disorder is common and should be sought in all neurodegenerative diseases. They are included among clinical disorders due to the resulting injuries, and adverse health and psychosocial effects, which may affect the bed partner as well as the patient. Finally, parasomnias are common disturbances of sleep that may significantly affect the patient’s quality of life and that of the bed partner. Therefore, appropriate diagnostic and

    2010-01-01

    Full Text Available Hepatocellular carcinoma (HCC represents the fifth most common cancer in the world, and the third most frequent oncological cause of death. The incidence of HCC is on the increase. HCC typically develops in patients with chronic liver diseases, and cirrhosis, usually with viral etiology, is the strongest predisposing factor. Nowadays HCC diagnosis is a multistage process including clinical, laboratory, imaging and pathological examinations. The prognosis of HCC is mostly poor, because of detection at an advanced, non-resectable stage. Potentially curative treatment (surgery is limited and really possible only for cases with small HCC malignancies. For this reason, more effective surveillance strategies should be used to screen for early occurrence of HCC targeted to the population at risk. So far, the generally accepted serological marker is α-fetoprotein (AFP. Its diagnostic accuracy is unsatisfactory and questionable because of low sensitivity, therefore there is a strong demand by clinicians for new HCC-specific biomarkers. In this review, we will focus on other biomarkers that seem to improve HCC diagnosis, such as AFP-L3, des-γ-carboxyprothrombin, α-l-fucosidase, γ-glutamyl transferase, glypican-3, squamous cell carcinoma antigen, a new generation of immunoglobulin M-immunocomplexes, and very promising gene-expression profiling.

  5. Abdominal tuberculosis: clinical presentation and outcome

    International Nuclear Information System (INIS)

    To study the clinical presentation and outcome of cases of Abdominal Tuberculosis. Fifty four patients of Abdominal Tuberculosis were seen during the study period. Four patients were lost to follow-up, which were excluded. Detailed information of all the patients including age, sex, symptoms, signs, investigations and management was recorded, analyzed and compared with local and international data. Out of the 50 patients with Abdominal Tuberculosis, 31 were females and 19 males. Their ages ranged from 17 to 63 years, with a mean age of 25.1 years. Thirty five cases were admitted through Emergency and 15 through Outpatients departments. Abdominal pain was the most common symptom found in 44 (88%) patients followed by vomiting in 33 (66%). Abdominal tenderness was seen in 22 (44%) patients, while 16 (32%) patients had rigidity and other features of peritonitis. Surgery was performed in all these patients, limited right hemicolectomy in 17 (34%), segmental resection and anastomosis in 12 (24%), ileostomy and strictureplasty in six (12%) each, repair of perforation in five (10%) and adhesiolysis in four (8%) patients. Overall mortality was 8% due to septicaemia and multiorgan failure. Abdominal Tuberculosis is a significant clinical entity with lethal complications in neglected cases. It affects a younger age group and is more common in females. Clinical features are rather non-specific but vague ill health, low grade fever, weight loss and anorexia may help to diagnose the case.

The thesis demonstrates how confounding by indication hampers the epidemiological study design by masking the actual effect of delay. For obvious clinical reasons, doctors respond faster to patients who are clinically very sick and have clear...... than other patients. Some studies illustrating this paradox take the results to show no association and find them reassuring. The aim of this thesis was to validly identify an underlying relation between delayed diagnosis and mortality by exploring the association between time from first presentation...... of symptoms in primary care to diagnosis (the diagnostic interval) and mortality after diagnosis of cancer.

    Full Text Available Children regularly and voluntarily go to school in order to fulfill the expectations of society from them to continue their education or schooling. School continuation has been made compulsory by laws. Nonetheless, contrary to popular belief, for some children it is distressing to go to school. These children have difficulty continuing school and/or refuse to go to school. Today school refusal is defined as a child’s inability to continue school for reasons, such as anxiety and depression. The prevalence of school refusal has been reported to be approximately 1% in school-age children and 5% in child psychiatry samples. The prevalence of school refusal is similar among boys and girls. School refusal can occur at any time throughout the child’s academic life and at all socio-economic levels. School refusal is considered a symptom rather than a clinical diagnosis and can manifest itself as a sign of many psychiatric disorders, with anxiety disorders predominant. Separation anxiety disorder, generalized anxiety disorder, social phobia, specific phobia, and adjustment disorder with anxiety symptoms are the most common disorders co-occurring with school refusal. While separation anxiety disorder is associated with school refusal in younger children, other anxiety disorders, especially phobias, are associated with school refusal in adolescents. Children who have parents with psychiatric disorders have a higher incidence of school refusal, and psychiatric disorders are more frequently seen in adult relatives of children with school refusal, which supports a significant role of genetic and environmental factors in th etiology of school refusal. School refusal is a emergency state for child mental health. As it leads to detrimental effects in the short term and the long term, it should be regarded as a serious problem. The long-lasting follow-up studies of school refusing children have revealed that these children have a higher incidence of

    Full Text Available Pompe disease is a rare inherited disease that belongs to lysosomal accumulation diseases and can be considered as cardiac glycogenosistype II, as well as a severe neuromuscular disease or metabolic myopathy. Physicians of different specialties very rarely identify this pathology, which is due to both its rarity and clinical and genetic polymorphism. Infantile Pompe disease is the severest form. It is characterized by a progressive pattern and a fatal outcome during the first year of life. The possibility of performing enzyme replacement therapy for this disease, which can improve the prognosis and quality of life of patients, makes the early diagnosis of Pompe disease urgent. The paper describes the clinical presentation of infantile Pompe disease and current methods for its diagnosis and treatment. The authors give their experience in diagnosing and treating infantile Pompe disease, by demonstrating 3 cases of the disease. The characteristics of each infant, which confirm the clinical and genetic variety of this pathology, are discussed.

    The aim of this paper is to provide a broad international perspective on aspects of the RTI/UNC systematic review, to introduce relevant literature not cited, and to make recommendations for clinical practice education and research suggested by the evidence. Clinical caries diagnosis represents the foundation on which the answers to most of the consensus questions will be based. This paper highlights needs for being clear about definitions and nomenclature; understanding the importance of the concepts underlying the D1 and D3 diagnostic thresholds used widely within the RTI/UNC Review; and appreciating that the diagnostic challenge now faced by clinicians is significant and is becoming more complex as the presentation and distribution of the disease changes over time and the range of preventive and operative treatment options expands. A series of recommendations informed by the evidence are made, including a rather contentious issue for many clinicians concerning the lack of evidence supporting the continued use of a sharp explorer as a diagnostic tool for primary caries diagnosis. This practice should be discontinued as it may cause some harm to the patient and yet fails to provide a significant balancing diagnostic benefit. Finally, it is suggested that dentistry should learn from the developing evidence base in medicine on how best to disseminate the findings of reviews and promote appropriate changes in clinical practice.

    International Nuclear Information System (INIS)

    Early diagnosis of Alzheimer's disease describes the recognition and diagnosis in patients with very mild dementia. Internationally accepted diagnostic criteria support the diagnosis based on clinical evaluation. Recent advances in structural and functional neuroimaging as well as studies on specific proteins in the cerebro-spinal fluid that are related to distinct pathophysiological disease processes are most promising approaches to defining biological markers of Alzheimer's disease.

  12. Central pontine myelinolysis: clinical presentation and radiologic findings

    International Nuclear Information System (INIS)

    Central pontine myelinolysis (CPM) is a neurologic disorder once thought to be uniformly fatal. With the introduction of CT and MRI there was an increasing number of reports on nonfatal cases of CPM. Nearly all reports on nonfata cases describe severe clinical syndromes with tetraparesis, bulbar palsy, and coma. We reviewed nine patients with CPM and compared the size of the pontine lesion on MRI and CT with the severity of clinical presentation. Clinical presentation of CPM was highly variable: The symptoms ranged from severe neurologic disorders to mild neurologic disturbances only. Two of nine patients died from CPM. The size of the pontine lesion did not correlate with the severity of the neurologic illness or the final outcome. Mild forms of CPM might be difficult to diagnose clinically. This applies even more for patients with underlying diseases such as Wernicke's encephalopathy, which in itself might cause a clinical picture similar to that of CPM. Central Pontine Myelinolysis is a major differential diagnosis in acute neurologic deterioration indicating pontine damage. Magnetic resonance imaging is the decisive diagnostic tool for CPM.

    Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae,which primarily affects the skin and peripheral nerves.In this article,we present a 45-year-old man and a 39-year-old women who suffered fróm asymptomatic irregular erythemas on their trunk and extremities.Since both patients denied the history of exposure to leprosy patients and were absent clinical signs of superficial sensation dysfunction and enlarged peripheral nerves,they were diagnosed of mycosis fungoides and livedo reticularis clinically.Nevertheless the biopsies of erythemas showed perineural and periadnexal foamy-cell granulomas in the dermis and Fite staining revealed a large number of acid-fast bacilli.A diagnosis of multibacillary leprosy was made finally.These cases revealed that since leprosy is still epidemic in some remote area in China and in other developing countries and its clinical manifestations may be very weird sometimes,the dermatologists should be alert of it and skin biopsy could confirm the diagnosis.

    2014-04-01

    Full Text Available High myopia associated with cone dystrophy is relatively rare in clinical practice. Because the two diseases have a certain genetic predisposition, with the disease developed, clinical examination and clinical symptoms have some similarities, one disease diagnosis is easily confused or masked by the other diagnosis, especially in the face of patients with high myopia associated abnormalities, we should carefully screen abnormal visual function of its own or combined cone dystrophy diagnosis. In addition, the development of the disease may mutually reinforce, aggravate the symptoms of each other, which is likely to cause mission or misdiagnosis, or delay the proper treatment. Therefore, it is clinically difficult to correct and comprehensively and timely diagnosis.

    Ebola virus disease is caused by a highly contagious and pathogenic threadlike RNA virus of the Filoviridae family. The index human case is usually a zoonosis that launches human-to-human transmission interface with varying levels of sustainability of the epidemic depending on the level of public health preparedness of the affected country and the Ebola virus strain. The disease affects all age groups in the population. Clinical diagnosis is challenging in index cases especially in the early stages of the disease when the presenting features are usually nonspecific and only similar to a flu-like illness. However, in the agonal stages, hemorrhage frequently occurs in a high proportion of cases. The diagnostic gold standard is by detecting the antigen using reverse transcription-polymerase chain reaction. Mortality rates in the past 28 outbreaks since 1976 have ranged from 30% to 100% in different settings among adults, but lower mortality rates have been documented in children. This review aims to describe Ebola virus infection, clinical presentation, diagnosis and outcomes in children. PMID:25522340

    Multiple mononeuropathy is an unusual form of peripheral neuropathy involving two or more nerve trunks. It is a syndrome with many different causes. We reviewed the clinical, electrophysi-ological and nerve biopsy ifndings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neurop-athy (n = 6), perineuritis (n = 2), chronic inlfammatory demyelinating polyradiculoneuropathy (n = 2) or Lewis-Sumner syndrome (n = 1) on the basis of clinical features, laboratory data, elec-trophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inlfamma-tory demyelinating polyradiculoneuropathy were not conifrmed by nerve biopsy. Nerve biopsies conifrmed clinical diagnosis in 78.6% of the patients (11/14). Nerve biopsy pathological diagno-sis is crucial to the etiological diagnosis of multiple mononeuropathy.

    2012-01-01

    Full Text Available The aim of the study was to establish the characteristics of presentation of 94 patients with Kinelfelter's syndrome (KS referred to the endocrinologist at different ages. The diagnosis of KS was more frequent in the age group between 11 and 20 years (46.8%. Most of the patients (83.7% showed the classic 47,XXY karyotype and 7.1% showed a 47,XXY/46,XY mosaicism. Half of the patients younger than 18 years presented mild neurodevelopmental disorders. The most frequent clinical findings were cryptorchidism in prepubertal patients, and small testes, cryptorchidism, and gynecomastia in pubertal patients. FSH, LH, AMH, and inhibin B levels were normal in prepubertal patients and became abnormal from midpuberty. Most adults were referred for small testes, infertility, and gynecomastia; 43.6% had sexual dysfunction. Testosterone levels were low in 45%. Mean stature was above the 50th percentile, and 62.5% had BMI ≥25.0 kg/m2. In conclusion, the diagnosis of Klinefelter syndrome seems to be made earlier nowadays probably because pediatricians are more aware that boys and adolescents with neuro-developmental disorders and cryptorchidism are at increased risk. The increasing use of prenatal diagnosis has also decreased the mean age at diagnosis and allowed to get insight into the evolution of previously undiagnosed cases, which probably represent the mildest forms. In adults average height and weight are slightly higher than those in the normal population. Bone mineral density is mildly affected, more at the spine than at the femoral neck level, in less than half of cases.

SRMs have allowed discussions regarding their prognostic, diagnosis, and therapeutic approach. Materials and methods. Clinical presentation, incidental diagnosis, and prognosis factors of SRMs are discussed in this review. Results. SRMs are defined as lesions less than 4 cm in diameter. SRM could be benign, and most malignant SMRs are low stage and low grade. Clinical symptoms like hematuria are very rare, being diagnosed by chance (incidental in most cases. Size, stage, and grade are still the most consistent prognosis factors in (RCC. An enhanced contrast SRM that grows during active surveillance is clearly malignant, and its aggressive potential increases in those greater than 3 cm. Clear cell carcinoma is the most frequent cellular type of malign SRM. Conclusions. Only some SRMs are benign. The great majority of malign SRMs have good prognosis (low stage and grade, no metastasis with open or laparoscopic surgical treatment (nephron sparing techniques. Active surveillance is an accepted attitude in selected cases.

    It is considered that the structural damage in early osteoarthritis (OA) is potentially reversible. It is therefore particularly important for orthopaedic and trauma surgery to develop strategies and technologies for diagnosing early OA processes. This review presents 3 case reports to illustrate the current clinical diagnostic procedure for OA. Experimental techniques with translational character are discussed in the context of the detection of early degenerative processes relevant to OA. Non-invasive imaging methods such as quantitative MRI, ultrasound, optical coherence tomography (OCT), scintigraphy and diffraction-enhanced synchrotron imaging (DEI), as well as biochemical methods and proteomics, are considered. Early detection of OA is reviewed with minimally invasive techniques, such as arthroscopy, as well as the combination of arthroscopic techniques with indentation, spectrometry, and multiphoton microscopy. In addition, a brief summary of macroscopic and histologic scores is presented. Finally, the spatial organisation of joint surface chondrocytes as an image-based biomarker is used to illustrate an early OA detection strategy that focusses on early changes in tissue architecture potentially prior to damage. In summary, multiple translational techniques are able to detect early OA processes but we do not know whether they truly represent the initial events. Moreover, at this point it is difficult to judge the future clinical relevance of these procedures and to compare their efficacy, as there have been comparative studies. However, the expected gain in knowledge will hopefully help us top attain a more comprehensive understanding of early OA and to develop novel methods for its early diagnosis, therapy, and prevention. Overall, the clinical diagnosis of early OA remains one of the greatest challenges of our field. We still face uncharted territory. PMID:26894867

  6. Clinical value of in vitro tests in thyroid diagnosis

    International Nuclear Information System (INIS)

    Since various new in vitro tests, partially involving new parameters, have been introduced into routine diagnostics during the past ten years, the aim of this contribution is to discuss their clinical value. This applies particularly to the determination of free thyroid hormones, TSH receptor antibodies, the supersensitively determined basal TSH level as well as to the tumour markers thyroglobulin and calcitonin. In radioligand assays the free thyroid hormones, FT4 and FT3, are of high clinical value, comparable to that of the indirect parameters, of the FT4 and FT3 indexes and the T4/TBG and T3/TBG ratios. TSH receptor antibodies are useful for differential diagnosis of hyperthyroidism whereas their clinical value in the follow-up of immunohyperthyroidism is controversial. The supersensitively determined basal TSH enables to predict the result of the TRH test, and there is a tendency towards replacement of the latter one. Furthermore, the use of the basal TSH as a primary screening test is discussed. However, particularly with regard to special cases, the TRH test must not be regarded as obsolete at present. Thyroglobulin and calcitonin are tumour markers of very high clinical value in differentiated or medullary thyroid carcinoma, respectively. (orig.)

  7. Present trends in laboratory diagnosis of thyroid glands

    International Nuclear Information System (INIS)

    A brief survey is presented of the main in vitro methods presently used in the diagnosis of disorders of the thyroid gland. Next to the determination of total thyroxine, the determination of TSH (thyroid stimulating hormone) has come to the fore as a test used for verifying hypothyrosis and hyperthyrosis. Modern methods for the so-called direct determination of free thyroid hormones, primarily free thyroxine which in recent years aroused great hopes as a means of rapid and accurate assessment of the function of the gland also have their limitations and do not resolve controversial problems related to the accurate determination of total free thyroxine. The direct determination of concentrations of TBG (thyroxine-binding globulin) is a complement of thyroid function tests only in case of suspect abnormality of TBG concentration. The determination of thyroglobulin is considered to be useful in differentiated carcinoma of the thyroid gland as an indicator of relapse and the new early incidence of metastases in patients following surgery and isotope destruction of the thyroid gland and metastases. Next to radioisotope methods (radioimmunoassay and the radioimmunometric method) enzyme immunoassay methods are being used in in vitro diagnostics of the thyroid gland. (author). 1 tab., 20 refs

    Objective: To determine the most common clinical presentation and causative microorganism for acute appendicitis. Study Design: Descriptive. Place and duration of study: Department of Surgery, Combined Military Hospital Multan, from June 2002 to May 2004. Patients and Methods: Clinical features of all the patients, older than 5 years of age diagnosed with acute appendicitis were recorded. Patients presented with other pathology which mimic acute appendicitis were excluded from the study. Surgery was done under general anaesthesia. Appendices of all the patient as well as pus swabs from abdominal cavity were sent to the laboratory for histopathology and microbiological cultures to confirm the diagnoses of acute appendicitis and causative organism. Results: The mean age of 75 subjects was 32.56 +- 11.93 years. The most common symptom was pain in right iliac fossa (80 % cases) and the most common physical sign was tenderness (92% cases). Some of the patients(9.3%) had a histologically normal appendix. Maximum isolates on culture were E. coli. Conclusion: The most common presentation of acute appendicitis was pain in right iliac fossa while the most sensitive sign was tenderness. Proper history and sharp clinical examination is the key to diagnosis. The most frequent organism of appendicitis was Escherichia Coli. (author)

    The origin of halitosis comes from the Latin word "halitus" meaning 'breath, exhaled air', and in the Hungarian terminology it means bad and smelly breath. The human body emits a number of volatile molecules, which have a peculiar odour. Their presence is influenced by several factors, such as genetic, nutritional and psychological factors. Since bad breath belongs to taboo subjects, halitosis can often lead to social isolation. To determine the incidence of halitosis, an exact diagnosis is needed which sometimes predestinates the possible treatment as well. Investigators estimate the incidence about 50% in the whole population. The male/female ratio is the same and the incidence is growing with age. The diagnosis can be genuine halitosis, pseudo halitosis and halitophobia. We can divide the genuine type into physiological and pathophysiological subtypes. The cause of the halitosis usually can be found in the oral cavity. The volatile sulfur compounds (VSC) produced by some of the oral bacteria are responsible for its development. Only 10% of the causes are extraoral, mostly inflammation of airways or gastrointestinal disorders. The judgment of halitosis is based on three objective methods: the organoleptic, the sulphide monitoring and the gas cromatography methods. Since the origin of the halitosis is mainly the oral cavity, dentists should treat them. Beyond the dental treatments the enhancement of the oral hygiene, the continuous motivation and monitoring are also very important, such as the use of tongue cleansing and special anti-malodour rinses.

    Full Text Available Spinal muscular atrophy (SMA is a common autosomal recessive neuromuscular disease caused by degeneration of anterior horn cell in spinal cord. The clinical feature is characterized by progressive symmetrical myasthenia and amyotrophia. The disease is caused by mutation of survival motor neuron (SMN1 gene. Four clinical types are defined for SMA: type Ⅰ, Ⅱ, Ⅲ and Ⅳ. The diagnosis depends on clinical manifestation, inherited history, laboratory test and genetic analysis. To date, there is no effective treatment for SMA, so prenatal diagnosis and carrier screening are important for the prevention of this disease.

    Graves' disease and toxic uni- or multinodular goiter are the most frequent causes of hyperthyroidism. Graves' disease is caused by thyroid stimulating immunoglobulins which are directed against the TSH receptor of thyroid follicular cells. Graves' disease affects more females than males and is associated with diffuse goiter and a rapid appearance of symptoms and signs of hyperthyroidism. Patients with Graves' disease are on average younger than patients with toxic nodular goiter. The diagnosis of Graves' disease is usually easy, particularly if signs of endocrine opthalmopathy are present. Toxic nodular goiter is seen more often in older patients with pre-existing goiters. Symptoms and signs of hyperthyroidism often appear only slowly. Hyperthyroidism in these older patients can be oligosymptomatic. Older patients should therefore be investigated for the presence of hyperthyroidism, even if they present only a few symptoms or signs which could suggest this diagnosis. The development of ultrasensitive TSH assays has simplified the diagnosis of hyperthyroidism and made the TRH-test, often used in the past, almost superfluous. At the present time, it is practically always possible to differentiate between Graves' disease and toxic nodular goiter as the cause of hyperthyroidism on the basis of clinical and laboratory findings alone, and in many cases thyroid scintiscans are therefore no longer necessary. A patient with newly diagnosed Graves' disease is treated with antithyroid drugs (carbimazole or PTU) for one year. If hyperthyroidism persists after this one year of antithyroid drug treatment, or if it recurs, another year of therapy with carbimazole or PTU is indicated.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7545825

    International Nuclear Information System (INIS)

    To determine the demographic features and clinical outcome of children with Factor XIII deficiency. Records of all hospitalized pediatric patients with discharge diagnosis of FXIII D, on the basis of factor XIII assay 5 mol/L urea test were retrospectively reviewed and abstracted on a pre-specified proforma. Demographic features, coagulation profile, family history and outcomes were noted. A total of 10 charts were reviewed. There were 5 boys and 5 girls. Almost all the children (9/10) were less than 5 years of age, out of whom 5 (50%) were infants, and 3 were neonates. Bruises and prolonged bleeding after trauma was the major presenting complaints in 80%, followed by prolonged bleeding from the umbilical stump in 2 patients. Nine patients had past history of prolonged umbilical bleeding. Two patients had history of FXIII D in siblings, while 2 had history of prolonged bleeding in other family members (cause unknown). Consanguinity was present in 80% of the families. Initial coagulation screen were normal in all patients. Two patients had intracranial hemorrhage, proved on neuro-imaging, were managed with plasma infusions and required craniotomy. The rest were managed conservatively with plasma transfusions. All were discharged alive in good clinical condition. Almost all were followed regularly in clinic with monthly cryoprecipitate transfusions. Although factor XIII deficiency is a rare genetic disorder in children with history of bruising, prolonged umbilical bleeding, family history of bleeding and consanguinity with normal initial coagulation screen (PT, APTT and platelets), FXIII D should be ruled out.

    Fifty-two patients with caseous pneumonia (CP) (whose age ranged from 18 to 60 years) admitted to a specialized tuberculosis facility of the general health care system were followed up. On admission, all the patients had marked intoxication and bronchopulmonary manifestations of the disease. X-study revealed lesions to one lobe in 19.2%, to 2 lobes in 32.7%, to 3 lobes or more in 48.1% of the patients. At the same time, all the patients had destructive changes with large and giants caverns in 57.7% of cases. The sputa of all 52 patients exhibited Mycobacteria tuberculosis (MBT), whose primary drug resistance being established. The nonspecific microflora composed of gram-positive cocci, gram-negative bacilli, fungi of the genus Candida in over 60% of patients was found in the sputa in two thirds of cases. A retrospective analysis indicated that CP had been correctly diagnosed only in 11.5% of patients within the first fortnight, in 65.4% by the end of the first month and by the beginning of the second, and in 23.1% following 2 months. The main reason for untimely diagnosis of CP was no sputum test for MBT. An algorithm of early CP diagnosis at general hospitals was developed, which includes a compulsory test of 3 sputum smears by the Ziehl-Nielsen method in all patients with pneumonia on admission and 2 weeks after treatment with wide-spectrum antibiotics. Chemotherapy in CP patients was long-term and combined 4-5 essential drugs within the first 4 months with obligatory correction after there was evidence for drug resistance. A course of nonspecific antibiotic therapy and a developed complex of symptomatic and pathogenetic treatments were compulsory. By the cessation of bacterial isolation, the efficiency of combined treatment was 82.7%, but a question as to a surgical intervention that is a compulsory component of CP therapy always arose at the final stage.

    2016-07-01

    Dermatologists care for skin, hair, and nails, yet many dermatologists find nail disorders challenging. Practice gaps in knowledge, skill, and attitude in clinical practice and resident education are sometimes impediments to timely medical and surgical diagnosis of nail disorders. Limited resident exposure to diagnosis and management of complicated nail disorders and lack of experience performing diagnostic and surgical procedures impairs progress toward surmounting these gaps.

    Full Text Available Abstract: Introduction: Leptospirosis is an acute febrile disease caused by the leptospira. It is considered a zoonosis that affects a variety of animals, both wild and domestic (mainly rodents. Humans become infected accidentally by contact with urine or tissues from infected animals. This pathology has variable clinical manifestations, ranging from inapparent infections and aseptic meningitis, to severe forms such as the Weil syndrome. Development: We present the case of a young patient of 22 years old with fever quantified peaks of 40° C, chills, profuse sweating, headache, muscle and joint pain in knees and malleoli, retroorbital and retrosternal pain; and appetite loss. The symptoms occurred after 20 days of having practiced extreme water sports. Conclusion: The late diagnosis of the patient and hospital readmission are the result of several factors; First, the homology with other infectious diseases that present acute febrile illness with similar symptoms as dengue , malaria, influenza , yellow fever , brucellosis; and secondly the lack of expertise and poor contact with patients who present this disease by the medical staff. Correct antibiotic treatment and proper support reduce morbidity and mortality. The objective of this article is to describe a case of human leptospirosis and make a review of the literature in order to analyze the epidemiological characteristics and relevant clinical manifestations.

  1. The early clinical features of dengue in adults: challenges for early clinical diagnosis.

    Directory of Open Access Journals (Sweden)

    Jenny G H Low

    Full Text Available BACKGROUND: The emergence of dengue throughout the tropical world is affecting an increasing proportion of adult cases. The clinical features of dengue in different age groups have not been well examined, especially in the context of early clinical diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: We structured a prospective study of adults (≥ 18 years of age presenting with acute febrile illness within 72 hours from illness onset upon informed consent. Patients were followed up over a 3-4 week period to determine the clinical outcome. A total of 2,129 adults were enrolled in the study, of which 250 (11.7% had dengue. Differences in the rates of dengue-associated symptoms resulted in high sensitivities when the WHO 1997 or 2009 classification schemes for probable dengue fever were applied to the cohort. However, when the cases were stratified into age groups, fewer older adults reported symptoms such as myalgia, arthralgia, retro-orbital pain and mucosal bleeding, resulting in reduced sensitivity of the WHO classification schemes. On the other hand, the risks of severe dengue and hospitalization were not diminished in older adults, indicating that this group of patients can benefit from early diagnosis, especially when an antiviral drug becomes available. Our data also suggests that older adults who present with fever and leukopenia should be tested for dengue, even in the absence of other symptoms. CONCLUSION: Early clinical diagnosis based on previously defined symptoms that are associated with dengue, even when used in the schematics of both the WHO 1997 and 2009 classifications, is difficult in older adults.

    Wernicke encephalopathy (WE) is a severe neurological disorder caused by vitamin B1 deficiency. The aim of the study was to analyse MRI findings typical for this disease and to evaluate the significance of their correlations with clinical symptoms. Magnetic resonance images and clinical features of 12 patients with WE were analysed. The patients underwent MR imaging within 3-14 days after onset of clinical symptoms. In 7 of 12 patients MR imaging showed symmetrical diencephalic and midbrain lesions. Postcontrast T1-weighted images from 5 of 9 patients examined during the initial 6 days of acute WE showed a subtle enhancement of the mamillary bodies, the tectal plate, the periaqueductal area and the periventricular region of the third ventricle including the paramedian thalamic nuclei. In addition, T2-weighted and fluid-attenuated inversion recovery (FLAIR) images revealed hyperintense signals in these regions (except for 2 patients where the mamillary bodies were normal). Hyperintense lesions on T2-weighted images without any enhancement on postcontrast T1-weighted images were detected in 2 patients by MR imaging performed 11 or 14 days after onset of WE. Patients with hyperintensities on T2-weighted images of the periventricular region of the third ventricle and the paramedian thalamic nuclei had poor recovery from their mental dysfunction. The MR examination in case of WE shows a typical pattern of lesions in 58% of cases. Enhancement of the mamillary bodies, the periventricular region of the third ventricle including the paramedian thalamic nuclei, and the periaqueductal area on postcontrast T1-weighted images can be observed in the initial period after clinical onset of symptoms and are characteristic signs of the acute stage of WE. Hyperintense lesions in the periventricular region and the paramedian thalamic nuclei on T2-weighted and FLAIR images in the subacute stage of WE and enhancement on postcontrast T1-weighted images of the mamillary bodies and the

  4. A case of clinical Reye syndrome presenting characteristic CT changes

    International Nuclear Information System (INIS)

    A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease. (author)

    Full Text Available The paper describes spinal dural arteriovenous fistulas (SDAVF, the most common type of spinal cord vascular anomalies. SDAVFs account for 60–80% of the spinal cord vascular anomalies. The causes of SDAVFs, the specific features of their hemodynamics, and their classification remain the subject matter of disputes.SDAVFs form in dura mater tissue, on the dorsal surface of radicular cuffs. The pathogenesis of neurological disorders in SDAVF has determined the name «venous hypertensive myelopathy», a spinal cord injury occurring in their presence. Pain and paresthesias, cacesthesia (more commonly in their distal parts, and motor disorders as flail legs are observed at the onset of SDAVF in typical cases. On average, 12 to 44 months elapse to establish its diagnosis. In addition of motor and sensory disorders, sphincter impairments and sexual dysfunction are detected in the patients at the time of diagnosis. By this time, most patients have already neurological disability.The paper presents the history of studying SDAVF, the existing classifications of arteriovenous malformations and fistulas, the clinical manifestations of venous hypertensive myelopathy in SDAVF, neuroimaging findings, and treatment options.

    Full Text Available Few studies have been reported from the Kingdom of Saudi Arabia (SA to describe the clinical presentation and long term outcomes of subacute thyroiditis (SAT. Our aim was to review the demographic, anthropometric, clinical presentation, laboratory results, treatment, and disease outcome in Riyadh region and to compare those with results from different regions of the Kingdom and different parts of the world. We reviewed the medical files of patients who underwent thyroid uptake scan during an 8-year period in King Khalid University Hospital. Only 25 patients had confirmed diagnosis of thyroiditis. Age and gender distribution were similar to other studies. Most patients presented with palpitation, goiter, and weight change. Elevated thyroid hormones, suppressed thyroid-stimulating hormone, and elevated ESR were reported. Among those, 7 cases of SAT were recorded. β-Blockers were prescribed to 57% and nonsteroidal anti-inflammatory drugs to 29% of SAT. Long follow-up demonstrated that 85.7% of SAT cases recovered, while 14.3% developed permanent hypothyroidism. In conclusion, SAT is uncommon in the central region of SA. Compared to the western region, corticosteroid is not commonly prescribed, and permanent hypothyroidism is not uncommon. A nation-wide epidemiological study to explain these interprovincial differences is warranted.

    Proliferative vitreoretinopathy (PVR) remains one of the most common causes of failed retinal detachment (RD) surgery. Many histological and clinical studies have highlighted the chain of events leading to PVR: cellular migration into the vitreous cavity, cellular differentiation, myofibroblast proliferation and activation, synthesis of extracellular matrix proteins, then contraction of preretinal tissues. The development of PVR can be explained schematically by cellular exposure to growth factors and cytokines (particularly retinal pigment epithelial cells and glial cells), in the context of break-down of the blood-retinal barrier (inflammation, choroidal detachment, iatrogenic effect of cryotherapy and surgery) and of cellular contact with the vitreous. Although the pathophysiology of PVR is now better understood, its severity remains an issue. A systematic search for preoperative PVR risk factors allows the most suitable therapeutic option to be chosen. PMID:24997864

    Filariasis is a disabling parasitic disease and the prevalence of lymphatic filariasis caused by Wuchereria bancrofti is quite high in India. However, W. bancrofti presenting as a subcutaneous swelling and a demonstration of microfilariae in cytological smears from upper extremity lesions is extremely rare. We report a case of 20-year-old male who presented with a small subcutaneous swelling near medial aspect of the left cubital fossa. The wet mount preparation showed many motile microfilariae. Cytology smears revealed a large number of sheathed microfilariae with the tail tip free of nucleus, identified as W. bancrofti without significant inflammatory cell infiltrate. Indirect ELISA was highly positive for specific recombinant W. bancrofti filarial antigen (WL-L2). The role of cytology cannot be underestimated in clinically unanticipated cases of bancroftian filariasis, especially with the amicrofilaremic state. Filariasis should always be considered in the differential diagnosis during cytological evaluation of any swelling, especially in endemic areas. PMID:26634138

    Objective: To make a clinical analysis on the basis of 36cases of atypical genital herpes (GH) patients. Methods: Thirty-six cases of atypical GH were diagnosedclinically, and their case histories, symptoms and signs wererecorded in detail and followed up. Polymerase chain reaction(PCR) was adopted for testing HSV2-DNA with cotton-tippedswabs. Enzyme-linked immuno sorbent assay (ELISA) forserum anti-HSV2-IgM was done to establish a definfiivediagnosis. Other diagnoses were excluded at the same time bytesting for related pathogens including fungi, Chlamydia,Mycoplasma, Treponema pallidum, gonococci, Trichomonas,etc. Results: The main clinical manifestations of atypical GHwere: (1) small genital ulcers; (2) inflammation of urethralmeatus; (3) nonspecific genital erythema; (4) papuloid noduleson the glands; (5) nonspecific vaginitis. Twenty-three cases(64%) tested by PCR were HSV2-DNA sera-positive, and 36cases (100 %) anti-HSV2-IgM sera-positive by ELISA. Conclusion: atypical HSV is difficult to be diagnosed. Butthe combination of PCR and ELIAS will be helpful to thediagnosis of atypical HSV.

    Full Text Available BACKGROUND: Pulmonary embolism (PE is a common and potentially fatal disease that is still underdiagnosed. The objective of our study was to reappraise the clinical presentation of PE with emphasis on the identification of the symptoms and signs that prompt the patients to seek medical attention. METHODOLOGY/PRINCIPAL FINDINGS: We studied 800 patients with PE from two different clinical settings: 440 were recruited in Pisa (Italy as part of the Prospective Investigative Study of Acute Pulmonary Embolism Diagnosis (PISAPED; 360 were diagnosed with and treated for PE in seven hospitals of central Tuscany, and evaluated at the Atherothrombotic Disorders Unit, Firenze (Italy, shortly after hospital discharge. We interviewed the patients directly using a standardized, self-administered questionnaire originally utilized in the PISAPED. The two samples differed significantly as regards age, proportion of outpatients, prevalence of unprovoked PE, and of active cancer. Sudden onset dyspnea was the most frequent symptom in both samples (81 and 78%, followed by chest pain (56 and 39%, fainting or syncope (26 and 22%, and hemoptysis (7 and 5%. At least one of the above symptoms was reported by 756 (94% of 800 patients. Isolated symptoms and signs of deep vein thrombosis occurred in 3% of the cases. Only 7 (1% of 800 patients had no symptoms before PE was diagnosed. CONCLUSIONS/SIGNIFICANCE: Most patients with PE feature at least one of four symptoms which, in decreasing order of frequency, are sudden onset dyspnea, chest pain, fainting (or syncope, and hemoptysis. The occurrence of such symptoms, if not explained otherwise, should alert the clinicians to consider PE in differential diagnosis, and order the appropriate objective test.

    Virtual colonoscopy provides techniques not available in optical colonoscopy, an exciting one being the ability to perform an electronic biopsy. An electronic biopsy image is created using ray-casting volume rendering of the CT data with a translucent transfer function mapping higher densities to red and lower densities to blue. The resulting image allows the physician to gain insight into the internal structure of polyps. Benign tissue and adenomas can be differentiated; the former will appear as homogeneously blue and the latter as irregular red structures. Although this technique is now common, is included with clinical systems, and has been used successfully for computer aided detection, there has so far been no study to evaluate the effectiveness of a physician using electronic biopsy in determining the pathological state of a polyp. We present here such a study, wherein an experienced radiologist ranked polyps based on electronic biopsy alone per scan (supine and prone), as well as both combined. Our results show a correct identification 77% of the time using prone or supine images alone, and 80% accuracy using both. Using ROC analysis based on this study with one reader and a modest sample size, the combined score is not significantly higher than using a single electronic biopsy image alone. However, our analysis indicates a trend of superiority for the combined ranking that deserves a follow-up confirmatory study with a larger sample and more readers. This study yields hope that an improved electronic biopsy technique could become a primary clinical diagnosis method.

    Full Text Available Purpose. The authors proposed that introducing real patients into a pathology classroom early in medical education would help integrate fundamental principles and disease pathology with clinical presentation and medical history. Methods. Three patients with different pathologies described their history and presentation without revealing their diagnosis. Students were required to submit a differential diagnosis in writing, and then were able to ask questions to arrive at the correct diagnosis. Students were surveyed on the efficacy of patient-based learning. Results. Average student scores on the differential diagnosis assignments significantly improved 32% during the course. From the survey, 72% of students felt that patient encounters should be included in the pathology course next year. Seventy-four percent felt that the differential diagnosis assignments helped them develop clinical decision-making skills. Seventy-three percent felt that the experience helped them know what questions to ask patients. Eighty-six percent felt that they obtained a better understanding of patients’ social and emotional challenges. Discussion. Having students work through the process of differential diagnosis formulation when encountering a real patient and their clinical presentation improved clinical decision-making skills and integrated fundamental concepts with disease pathology during a basic science pathology course.

    Full Text Available Neurotoxins have existed on the earth from times immemorial. Old neurotoxic disorders were due to ingestion/ exposure of heavy metals and food like lathyrus sativus over a long period of time. The 20th Century with rapid industrialsation and expanding chemical and drug industry has spawned several new, hitherto unknown disorders. Old disorders continue to exist e.g. fluorosis, arsenicosis, lathyrism, manganism and lead neuropathy, along with new diseases like Minamata disease, subacute myelo optic neuropathy (SMON, MPTP-Parkinsonian syndorme, triorthcresyl phosphate (TOCP neuroparalytic disease, pesticide induced seizures, tremor and neuropathy, solvent encephalopthy, antipileptic drug foetal syndrome and excitotoxin induced behavioural disorders. Studies on pesticides Organochlorine and organophosphates, synthetic pyrethrins, solvents, heavy metals and substances abuse in the Indian context confirm the neurotoxic nature of many synthetic substances. Future problems envisaged are of concern to clinical neurologists as many of these neurotoxic disorders mimic syndromes of well known neurological disease. The new millenium poses a challenge to the clinician as newer compounds in industry, food, drugs and chemical war agents are being developed. Molecular genetics has advanced rapidly with release of the human genome map. Animal cloning and genetically modified plant products have entered the food chain. How safe are these new inventions for the central nervous system is a big question? India cannot afford disasters like Union Carbide′s Bhopal gas leak nor be a silent spectator to manipulative biotechnology. Unless it is proven beyond all doubt to be a safe innovation, Chemicals have to be cautiously introduced in our environment. To Study, ascertain and confirm safety or neurotoxicity is an exciting challenge for the neuroscientists of the 21st century.

  1. Pathophysiology and clinical presentations of salt-losing tubulopathies.

    Science.gov (United States)

    Seyberth, Hannsjörg W

    2016-03-01

    At least three renal tubular segments are involved in the pathophysiology of salt-losing tubulopathies (SLTs). Whether the pathogenesis starts either in the thick ascending limb of the loop of Henle (TAL) or in the distal convoluted tubule (DCT), it is the function of the downstream-localized aldosterone sensitive distal tubule (ASDT) to contribute to the adaptation process. In isolated TAL defects (loop disorders) ASDT adaptation is supported by upregulation of DCT, whereas in DCT disorders the ASDT is complemented by upregulation of TAL function. This upregulation has a major impact on the clinical presentation of SLT patients. Taking into account both the symptoms and signs of primary tubular defect and of the secondary reactions of adaptation, a clinical diagnosis can be made that eventually leads to an appropriate therapy. In addition to salt wasting, as occurs in all SLTs, characteristic features of loop disorders are hypo- or isosthenuric polyuria and hypercalciuria, whereas characteristics of DCT disorders are hypokalemia and (symptomatic) hypomagnesemia. In both SLT categories, replacement of urinary losses is the primary goal of treatment. In loop disorders COX inhibitors are also recommended to mitigate polyuria, and in DCT disorders magnesium supplementation is essential for effective treatment. Of note, the combination of a salt- and potassium-rich diet together with an adequate fluid intake is always the basis of long-term treatment in all SLTs. PMID:26178649

  4. Parkinsonian syndroms: Clinical phenotype, differential diagnosis and disease progression

    International Nuclear Information System (INIS)

    Parkinsonian syndromes include idiopathic Parkinson's disease (IPD), other neurodegenerative diseases with parkinsonism, the so-called atypical parkinsonian syndromes, and symptomatic parkinsonian syndromes, such as Wilson's disease. IPD is the most frequent disease with parkinsonism as the main clinical feature and is responsible for approx. 80% of all parkinsonian syndromes. Atypical parkinsonian syndromes are the most important differential diagnoses of IPD. The two most frequent types are multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). For clinical diagnosis it is essential to take a careful medical history and to examine the patients physically in regular intervals. However, various clinico-pathological studies have shown that approx. 25% of patients with clinical diagnosis of IPD may have other causes of parkinsonism. Selected technical investigations, in particular functional imaging of the central dopaminergic system using PET or SPECT, may help to make clinical diagnosis more secure. This paper reviews the clinical features and diagnostic findings in diseases with parkinsonism and summarises the difficulties in establishing early and differential diagnoses. (orig.)

  5. Clinical diagnosis by computed tomography on Alzheimer type dementia

    International Nuclear Information System (INIS)

    The relationships of CT findings, intellectual impairment by psychological assessment and severity of dementia by clinical evaluation were studied on 109 patients with clinical diagnosis of Alzheimer type dementia (AD) and 43 controls. CT examinations were carried out on three tomographic sections, that is, a section through anterior and posterior horns of lateral ventricles, a section through cellae mediae of lateral ventricles and a section through cortex with intracranial space of 60-80 cm2. In the three tomographic sections, CSF space percent and half width full max (HWFM) in the histogram corresponding to brain tissue were employed as indexes of brain atrophy by CT. Psychological evaluation of dementia was made by using Hasegawa's dementia scale (HDS). The present study revealed the following findings. though CSF% in the sections through lateral ventricles significantly correlated with age, it was more significantly correlated with HDS and CDR(clinical dementia rating) scores, respectively. This finding seems to mean that the effect of dementia is so great as to override the effect of dementia. In the cortex slice, the correlations between CSF% and HDS and CDR scores were very low, though they were significant. HWFM in the same slice, showed the moderate and significant correlations with HDS and CDR scores, respectively, comparing with no relationship between HWFM and age. Concerning mean CSF% and HWFM of each group according to CDR staging, they increased with advancement of dementia. The significant differences between the groups by CDR, however, were not always obtained. According to CT indexes as independent variable, the normal subject were discriminated from the demented subjects in 82.6% of the total by discriminat analysis. (J.P.N.)

    Lobomycosis is a subcutaneous mycosis of chronic evolution caused by the Lacazia loboi fungus. Its distribution is almost exclusive in the Americas, and it has a particularly high prevalence in the Amazon basin. Cases of lobomycosis have been reported only in dolphins and humans. Its prevalence is higher among men who are active in the forest, such as rubber tappers, bushmen, miners, and Indian men. It is recognized that the traumatic implantation of the fungus on the skin is the route by which humans acquire this infection. The lesions affect mainly exposed areas such as the auricles and upper and lower limbs and are typically presented as keloid-like lesions. Currently, surgical removal is the therapeutic procedure of choice in initial cases. Despite the existing data and studies to date, the active immune mechanisms in this infection and its involvement in the control or development of lacaziosis have not been fully clarified. In recent years, little progress has been made in the appraisal of the epidemiologic aspects of the disease. So far, we have neither a population-based study nor any evaluation directed to the forest workers. PMID:25328400

    The diagnosis of Parkinson's disease (PD) follows the UK Brain Bank Criteria, which demands bradykinesia and one additional symptom, i.e. rigidity, resting tremor or postural instability. The latter is not a useful sign for the early diagnosis of PD, because it does not appear before Hoehn and Yahr stage 3. Early symptoms of PD which precede the onset of motor symptoms are hyposmia, REM sleep behavioral disorder, constipation, and depression. In addition, an increasing number of patients whose PD is related to a genetic defect are being described. Thus, genetic testing may eventually develop into a tool to identify at-risk patients. The clinical diagnosis of PD can be supported by levodopa or apomorphine tests. Imaging studies such as cranial CT or MRI are helpful to distinguish idiopathic PD from atypical or secondary PD. SPECT and PET methods are valuable to distinguish PD tremor from essential tremor if this is clinically not possible. Using all of these methods, we may soon be able to make a premotor diagnosis of PD, which will raise the question whether early treatment is possible and ethically and clinically advisable.

Its distribution is almost exclusive in the Americas, and it has a particularly high prevalence in the Amazon basin. Cases of lobomycosis have been reported only in dolphins and humans. Its prevalence is higher among men who are active in the forest, such as rubber tappers, bushmen, miners, and Indian men. It is recognized that the traumatic implantation of the fungus on the skin is the route by which humans acquire this infection. The lesions affect mainly exposed areas such as the auricles and upper and lower limbs and are typically presented as keloid-like lesions. Currently, surgical removal is the therapeutic procedure of choice in initial cases. Despite the existing data and studies to date, the active immune mechanisms in this infection and its involvement in the control or development of lacaziosis have not been fully clarified. In recent years, little progress has been made in the appraisal of the epidemiologic aspects of the disease. So far, we have neither a population-based study nor any evaluation directed to the forest workers. Keywords: infection, Lacazia loboi, lobomycosis, lacaziosis, mycosis

    Introduction: Osteoradionecrosis (ORN) of the jaws is defined as exposed irradiated bone that fails to heal over a period of 3 months without the evidence of a persisting or recurrent tumor. In the previous decades, numerous factors were associated with the risk of ORN development and severity. Aims: The purposes of this study were to present the data of the patients that were treated for ORN in the Department of Oral and Maxillofacial Surgery in Munich (LMU), to detect factors that contributed to the onset of ORN, to identify risk factors associated with the severity of ORN and finally, to delineate and correlate these factors with the personal, health and treatment characteristics of the patients. Material and Methods: A retrospective study was conducted during the period from January 2003 until December 2012 that included all ORN cases having been treated in the Department of Oral and Maxillofacial Surgery in Munich (LMU). The total sample was categorized in three groups according to stage and several variables were evaluated in an attempt to identify possible correlations between them and the necrosis severity. Results: One hundred and fifty three cases of ORN were documented. Among them, 23 (15.1%) cases were stage I, 31 (20.2%) were stage II and 99 (64.7%) were stage III and all localised in the mandible. There was a predominance of the disease in the posterior region when compared to the anterior region. The majority of cases was addicted to alcohol and tobacco abuse and was suffering from Diabetes Mellitus (DM). All cases were treated with RT and 80.4% of them with concomitant chemotherapy. The initial tumor was predominantly located in the floor of the mouth, the tongue and the pharynx. Approximately two thirds of the cases occured either after dental treatment or due to a local pathological condition. Logistic regression analysis identified Diabetes Mellitus (OR: 4.955, 95% Cl: 1.965-12.495), active smoking (OR: 13.542, 95% Cl: 2.085-87.947), excessive

    Full Text Available To evaluate clinical presentation, cranial imagining, and electroencephalic signs of SSPE patients, who are diagnosed with medical history, physical examination signs, EEG and CSF examinations. A total of 3 SSPE patients (mean age= 25.3 years, internalized into Department of Neurology Clinic of Medical School at Uludag University, were evaluated retrospectively. Clinical staging was performed by using Risk and Haddad’s classification. Time to SSPE diagnosis from initial symptoms was changing from 10 days to 3 months; cases applied to physician after a couple of months that their complaints were recognized. Weakening in mental capacities extracted the attention of the families. EEG examinations revealed slow baseline activity; penetrating slow discharges with high amplitudes regularly for every 8-10 seconds. While IgM for measles was negative, IgG was positive in CSF and serum samples of all cases. Valproic acid and clonazepam were given at various doses in the treatments, and all cases received isoprinosine, too. One of the cases died 13 months after the diagnosis. The other two cases are followed up. SSPE infection should be considered in central nervous system involvements of rapidly progressive, late onset adult diseases, since recently number of case reports in SSPE is increased rapidly.

    Full Text Available Abstract While diagnosis has traditionally been viewed as an essential concept in medicine, particularly when selecting treatments, we suggest that the use of diagnosis alone may be limited, particularly within mental health. The concept of clinical case formulation advocates for collaboratively working with patients to identify idiosyncratic aspects of their presentation and select interventions on this basis. Identifying individualized contributing factors, and how these could influence the person's presentation, in addition to attending to personal strengths, may allow the clinician a deeper understanding of a patient, result in a more personalized treatment approach, and potentially provide a better clinical outcome.

    International Nuclear Information System (INIS)

    Objective: To determine the etiology, clinical manifestation, management (medical and surgical) and complications of children with empyema thoracis in a tertiary care hospital from Karachi, Pakistan. Study Design: Descriptive, analytical study. Place and Duration of Study: Department of Surgery, The Aga Khan University Hospital, Karachi, from January 1996 to December 2010. Methodology: Medical records of admitted children aged > a month to 15 years with discharge diagnosis of empyema thoracis and data was collected on demographic features, clinical manifestation, management and complications. Children managed medically were compared with those managed surgically by using interquartile range and median comparison. Mann-Whitney U test was used to compare age in months, weight (kg) and length of stay in days and presenting complaint, duration of illness; chi-square test was used to compare thrombocytosis in between groups and p-value was calculated. Results: Among the 112 patients, 59 (53%) were younger than 5 years of age. Males (n=83, 74%) were predominant. Fifty (45%) children were admitted in winter. Thirty (27%) children found unvaccinated and one fourth (n=27; 24%) were severely malnourished. Fever, cough, and dyspnea were the major presenting symptoms. Sixty-six (59%) were on some antibiotics prior to admission. Staphylococcus aureus (n=13) and Streptococcus pneumoniae (n=5) were the commonest organism isolated from blood and pleural fluid cultures. Majority of the children required some surgical intervention (n=86). Surgically managed children were younger (p=0.01); had less weight (p=0.01) and prolonged fever (p=0.02); and stayed longer in hospital (p < 0.001) as compared to medically managed children. Requiring readmission (n=8), subcutaneous emphysema (n=5) and recollection of pus (n=5) were the major complications. Conclusion: Staphylococcus aureus was the major organism associated with paediatric empyema thoracis. Early identification and empiric

  17. Present state of computer-aided diagnosis (CAD) development

    International Nuclear Information System (INIS)

    Topics of computer-aided detection (CAD) are reviewed. Commercially available, Food and Drug Administration (FDA)-approved CAD systems are for fields of breast cancer (mammography), chest (flat X-ray and CT imaging) and colon (polyp detection). In Japan, only mammography CAD is approved. Efficacy of CAD is controversial, for which reliable database is important, and its construction is under development in various medical fields. Digitalized image is now popularized, which conceivably leads to improve the cost-effectiveness of diagnosis with CAD. For incentive, approval for health insurance would be the case as seen in the increased CAD sale by R2 Technology Co., and MHLW actually assists facilities to introduce the reading-aid system of mammography by sharing a half of its cost. There are 2 big projects for CAD study supported by MECSST, which the author concerns. One is the development of diagnostic aid for the multi-dimensional medical images where the multi-organ, multi-disease CAD system is considered. The other involves the CAD in brain MRI, in breast US and in eyeground picture. It is not in so far future for patients and doctors to fully enjoy the benefit of CAD. (R.T.)

    Laboratory diagnosis of Ebola virus disease plays a critical role in outbreak response efforts; however, establishing safe and expeditious testing strategies for this high-biosafety-level pathogen in resource-poor environments remains extremely challenging. Since the discovery of Ebola virus in 1976 via traditional viral culture techniques and electron microscopy, diagnostic methodologies have trended toward faster, more accurate molecular assays. Importantly, technological advances have been paired with increasing efforts to support decentralized diagnostic testing capacity that can be deployed at or near the point of patient care. The unprecedented scope of the 2014-2015 West Africa Ebola epidemic spurred tremendous innovation in this arena, and a variety of new diagnostic platforms that have the potential both to immediately improve ongoing surveillance efforts in West Africa and to transform future outbreak responses have reached the field. In this review, we describe the evolution of Ebola virus disease diagnostic testing and efforts to deploy field diagnostic laboratories in prior outbreaks. We then explore the diagnostic challenges pervading the 2014-2015 epidemic and provide a comprehensive examination of novel diagnostic tests that are likely to address some of these challenges moving forward.

    Full Text Available Patients with atypical odontalgia (AO complain of medically unexplained toothache. No evidence-based diagnostic criteria or treatment guidelines are yet available. The present paper addresses seven clinical questions about AO based on current knowledge in the literature and discusses diagnostic criteria and guidelines for treatment and management. The questions are (i What is the prevalence of AO in the community?\t(ii What psychological problems are experienced by patients with AO? (iii Are there any comorbidities of AO? (iv Is local anesthesia effective for the relief of pain in AO? (v Are there any characteristic symptoms of AO other than spontaneous pain? (vi Are antidepressants effective for treatment of AO? (vii Are anticonvulsants effective for treatment of AO? Our literature search provided answers for these questions; however, there is insufficient evidence-based data to establish guidelines for the diagnosis and treatment of AO. Overall, some diagnostic criteria for neuropathic pain and persistent dentoalveolar pain disorder may be applied to AO patients. The patient's psychogenic background should always be considered in the treatment and/or management of AO. The clinicians may need to treat AO patients using Patient-Oriented Evidence that Matters approach.

    Lomboy, Jason R; Coward, Robert M

    2016-09-01

    A varicocele is an abnormal dilatation and tortuosity of the veins of the spermatic cord. Although varicoceles are common in the general population and are frequently found on routine physical examinations, they represent the most common correctable cause of male factor infertility. Varicoceles are also often incidental findings on imaging studies, particularly scrotal ultrasound. Importantly, not all varicoceles should be treated equally (or at all), and basic guidelines on the evaluation and indications for treatment of adult varicoceles should be reviewed before counseling and treatment. A semen analysis should be obtained for any male patient of reproductive age considering intervention. The adolescent varicocele is managed much differently than the adult varicocele and remains a source of controversy. This review describes the clinical presentation and the evaluation of adult and pediatric varicoceles, and provides guidance on their diagnosis and workup. It also describes options for surgical repair and the success and complication rates associated with each surgical approach, ultimately supporting microsurgical subinguinal varicocele repair as the current surgical standard.

    2011-11-01

    Computer-aided diagnosis (CAD) is rapidly entering the radiology mainstream. It has already become a part of the routine clinical work for the detection of breast cancer with mammograms. The computer output is used as a "second opinion" in assisting radiologists' image interpretations. The computer algorithm generally consists of several steps that may include image processing, image feature analysis, and data classification via the use of tools such as artificial neural networks (ANN). In this article, we will explore these and other current processes that have come to be referred to as "artificial intelligence." One element of CAD, temporal subtraction, has been applied for enhancing interval changes and for suppressing unchanged structures (eg, normal structures) between 2 successive radiologic images. To reduce misregistration artifacts on the temporal subtraction images, a nonlinear image warping technique for matching the previous image to the current one has been developed. Development of the temporal subtraction method originated with chest radiographs, with the method subsequently being applied to chest computed tomography (CT) and nuclear medicine bone scans. The usefulness of the temporal subtraction method for bone scans was demonstrated by an observer study in which reading times and diagnostic accuracy improved significantly. An additional prospective clinical study verified that the temporal subtraction image could be used as a "second opinion" by radiologists with negligible detrimental effects. ANN was first used in 1990 for computerized differential diagnosis of interstitial lung diseases in CAD. Since then, ANN has been widely used in CAD schemes for the detection and diagnosis of various diseases in different imaging modalities, including the differential diagnosis of lung nodules and interstitial lung diseases in chest radiography, CT, and position emission tomography/CT. It is likely that CAD will be integrated into picture archiving and

History taking subsequently revealed that the patient was also experiencing intermittent numbness of his left lower lip, tinnitus, and a feeling of fullness in the left ear. Magnetic resonance imaging was performed which revealed a large vestibular schwannoma affecting the left vestibulocochlear nerve, which was treated surgically. This case shows the importance of taking a detailed history in a patient presenting with an initial complaint of oral dysgeusia. It also highlights the possibility of significant underlying pathology, presenting with initial low level, nonspecific complaints such as an altered taste, and the rationale for imaging patients who report unilateral facial hypoesthesia.

  12. MRI Diagnosis of Intracranial Hemorrhage : Experimental and Clinical Studies

    International Nuclear Information System (INIS)

    The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, and add knowledge about the newer sequences increasing in use to depict intra parenchymal bleeds, especially T2*-w GE sequences. We also compared the effect of magnetic field strengths. The sequences and field strengths were tested in animals. Then, the most effective technique was applied to patients with hematomas of different ages and with hematoma residuals. Occurrence of residuals of earlier, clinically silent, haemorrhages in patients with acute spontaneous hematoma or with suspected ischemic stroke were compared. Experimental studies: The MR detectability of small experimental haematomas in the brain and of blood in the cerebrospinal fluid (CSF) spaces of 30 rabbits was evaluated. MRI examinations were performed at determined intervals using different pulse sequences at two field strengths. The last MR images were compared to the formalin fixed brain sections and, in 16 rabbits, also to the histological findings. T2*-weighted GE sequences revealed all the intra parenchymal haematomas at 1.5 T: they were strongly hypointense. Their sizes became smaller but the signal patterns remained unchanged during the follow-up. The haematoma sizes and shapes corresponded well to gross pathology at acute and subacute stages. At chronic stage, the signal changes were larger than iron deposits. Blood in the CSF spaces was best detected at 1.5T with T2*-weighted GE sequences during the first 2 days. The FLAIR sequence often revealed blood in CSF spaces but not in the brain. SE sequences were rather insensitive. Imaging at 0.5 T was less effective than at 1.5 T. Clinical studies: All MR examinations on patients were performed at 1.5T, including T1- and T2-w SE, FLAIR, T2*-w GE sequences, and, occasionally, diffusion-w sequences. Sixty-six intra parenchymal hematomas were examined in the first clinical study. The hematomas were of different sizes and the ages varied from 8 hours to 3

Sixty-six intra parenchymal hematomas were examined in the first clinical study. The hematomas were of different sizes and the ages varied from 8 hours to 3

    The mucopolysaccharidoses (MPSs) are inherited lysosomal storage disorders caused by the absence of functional enzymes that contribute to the degradation of glycosaminoglycans (GAGs). The progressive systemic deposition of GAGs results in multi-organ system dysfunction that varies with the particular GAG deposited and the specific enzyme mutation(s) present. Cardiac involvement has been reported in all MPS syndromes and is a common and early feature, particularly for those with MPS I, II, and...

  15. Clinical application of EBCT in the diagnosis of cardiac neoplasms

    International Nuclear Information System (INIS)

    Objective: To probe the clinical utilization of electron beam CT (EBCT) in the diagnosis of cardiac neoplasms. Methods: Between July 1995 and Feb 1999. EBCT was performed in 12024 patients in our hospital. 40 (0.33%) patients were diagnosed as cardiac neoplasms. Retrospective analysis of 22 patients confirmed by operation, autopsy or follow-up was done. In this group, there were 13 males and 9 females, age ranged from 5 months to 72 years old (averaged 41.9 years). 17 patients had both contrast single slice mode (contrast SSM) and movie mode, 3 patients only SSM, 1 patient movie mode and 1 patient plain SSM. Results: Accurate localization and quantitative diagnoses were made in all the 22 patients and correct histopathological diagnosis was made in 10 patients with myxoma. EBCT provided characteristic clues to proper histopathological determination in 6 of the 7 patients with non-myxomatous benign neoplasms. In the 5 patients with malignant masses, 4 patients acquired distinct histopathological classifications, and involvement of the adjacent anatomic structures was revealed. Conclusion: Because of excellent temporal, spatial and density resolution, EBCT has not only high accuracy in the diagnosis of myxoma, but also possesses advantage superior to echocardiography in the definition of non-myxomatous benign and malignant neoplasms, which are difficult to diagnose histopathologically using echocardiography. EBCT is also valuable for assessment of involvement of neighbouring organs. In the diagnosis of cardiac neoplasm without specific features, this method is limited and difficult

    This review aims to give an update on the pathogenesis, clinical manifestations, and diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC). Arrhythmogenic right ventricular cardiomyopathy is mainly an autosomal dominant inherited disease linked to mutations in genes encoding desmosomes or desmosome-related proteins. Classic symptoms include palpitations, cardiac syncope, and aborted cardiac arrest due to ventricular arrhythmias. Heart failure may develop in later stages. Diagnosis is based on the presence of major and minor criteria from the Task Force Criteria revised in 2010 (TFC 2010), which includes evaluation of findings from six different diagnostic categories. Based on this, patients are classified as having possible, borderline, or definite ARVC. Imaging is important in ARVC diagnosis, including both echocardiography and cardiac magnetic resonance imaging for detecting structural and functional abnormalities, but importantly these findings may occur after electrical alterations and ventricular arrhythmias. Electrocardiograms (ECGs) and signal-averaged ECGs are analysed for depolarization and repolarization abnormalities, including T-wave inversions as the most common ECG alteration. Ventricular arrhythmias are common in ARVC and are considered a major diagnostic criterion if originating from the RV inferior wall or apex. Family history of ARVC and detection of an ARVC-related mutation are included in the TFC 2010 and emphasize the importance of family screening. Electrophysiological studies are not included in the diagnostic criteria, but may be important for differential diagnosis including RV outflow tract tachycardia. Further differential diagnoses include sarcoidosis, congenital abnormalities, myocarditis, pulmonary hypertension, dilated cardiomyopathy, and athletic cardiac adaptation, which may mimic ARVC.

    The diagnosis of syphilis can be complicated when it is based on diverse clinical manifestations, dark-field microscopy, and serology. In the present study, therefore, we examined the additional clinical value of a Treponema pallidum real-time TaqMan PCR for the detection of primary and secondary syphilis. The additional value of the T. pallidum real-time PCR for the diagnosis of primary syphilis was evaluated by the use of three different algorithms: (i) a head-to-head comparison of the dark-field microscopy result and the T. pallidum real-time PCR result, (ii) comparison of the clinical diagnosis made in a sexually transmitted infection clinic (STI) (including by dark-field microscopy) and the T. pallidum real-time PCR result, and (iii) comparison of the clinical diagnosis made in a general practitioner's office (without dark-field microscopy) and the T. pallidum real-time PCR result. A fourth algorithm was used to determine the performance of the T. pallidum real-time PCR regarding the detection of secondary syphilis. From December 2006 to April 2008, 716 patients with suspected cases of primary syphilis and 133 patients with suspected cases of secondary syphilis were included in the study. A kappa value of 0.601 was found for the agreement between dark-field microscopy and the T. pallidum real-time PCR. Good agreement was found between the T. pallidum real-time PCR and both the diagnosis of the general practitioner (kappa = 0.745) and the diagnosis of the STI clinic (kappa = 0.769). The sensitivity with respect to the STI clinic diagnosis was 72.8%, the specificity was 95.5%, the positive predictive value was 89.2%, and the negative predictive value was 95.0%. The T. pallidum real-time PCR is a fast, efficient, and reliable test for the diagnosis of primary syphilis in an STI outpatient clinic and a general practitioner setting, but it has no added diagnostic value for the diagnosis of secondary syphilis.

    Influenza is a descriptive term for respiratory epidemic disease presenting with cough and fever. Influenza viruses are probably the most important of the pathogens that cause this condition. Clinical influenza occurs almost every winter in England and Wales and the outbreaks last 8-10 weeks. In recent years, influenza B virus outbreaks have occurred in January and February, whereas influenza H3N2 virus outbreaks have generally started long before Christmas. Influenza H3N2 virus outbreaks pressurize health service resources in winter more than influenza B viruses, that do not have the same impact in elderly people. Infections with influenza H1N1 viruses are also usually less severe in their impact than those with influenza H3N2 viruses, but, unlike influenza B viruses, influenza H1N1 viruses have a pandemic potential along with influenza H3N2 viruses. A diagnosis of respiratory infection in primary care is based on the presenting symptoms set within the context of the current pattern of consultations of patients with similar illness. Measurement of temperature, inspection of the throat and examination of the chest or ears add a little to the diagnostic process, but in general these procedures do not help in identifying the organism. However, if it is known that influenza viruses are circulating in the community, the probability of influenza as the cause is greatly increased, as was shown in clinical trials of neuraminidase antivirals. Maximum confusion occurs when respiratory syncytial virus (RSV) and influenza cocirculate. Although RSV infection can occur throughout the winter in young children, it assumes more of an epidemic character just before Christmas in children and possibly in adults just after. During seven of the last 20 winters, influenza has been prevalent around Christmas/New Year. In routine virological surveillance of influenza-like illness in the community during the winters of 1997, 1998 and 1999, ca. 30% of swab specimens yielded influenza

    We describe the pattern of sensitisation to pet IgE components and its association with clinical symptoms. Hundred and fifty nine consecutive patients with rhinitis/asthma sensitised to dog, cat, and horse were recruited. Specific IgE to whole extracts and to pet recombinant allergens were performed. Only 5% of patients were monosensitised to animal allergens. Specific IgE to Can f 1 was significantly associated with persistent rhinitis, Can f 2 with asthma diagnosis, Can f 3 with moderate/severe rhinitis (M/S-R) and asthma diagnosis (AD), and Can f 5 with persistent and M/S-R. Positive IgE to Fel d 2 was significantly associated with M/S-R and AD, Equ c 1 with M/S-R and Equ c 3 with persistent rhinitis, AD and severe asthma. Sensitisation to ≥2 molecules or to pet albumins was associated with more severe respiratory symptoms. Molecular diagnosis in patients with pet allergy may also help clinicians to predict clinical symptoms and their severity. PMID:27108666

    Clinical applications of PET studies for dementia are reviewed in this paper. At the mild and moderate stages of Alzheimer's disease (AD), glucose metabolism is reduced not only in the parietotemporal region but also in the posterior cingulate and precuneus. At the advanced stage of AD, there is also a metabolic reduction in the frontal region. In AD patients, glucose metabolism is relatively preserved in the pons, sensorimotor cortices, primary visual cortices, basal ganglia, thalamus and cerebellum. In patients with dementia with Lewy bodies, glucose metabolism in the primary visual cortices is reduced, and this reduction appears to be associated with the reduction pattern in AD patients. In patients with frontotemporal dementia, reduced metabolism in the frontotemporal region is the main feature of this disease, but reduced metabolism in the basal ganglia, and/or parietal metabolic reduction can be associated with the frontotemporal reduction. When corticobasal degeneration is associated with dementia, the reduction pattern of dementia is similar to the reduction pattern in AD and the hallmarks of diagnosing corticobasal degeneration associated with dementia are a reduced metabolism in the primary sensorimotor region and/or basal ganglia and an asymmetric reduction in the two hemispheres. FDG-PET is a very useful tool for the diagnosis of early AD and for the differential diagnosis of dementia. I also describe clinical applications of PET for the diagnosis of dementia in Japan.

Physicians must be aware of typical clinical presentations (such as cervicofacial actinomycosis following dental focus of infection, pelvic actinomycosis in women with an intrauterine device, and pulmonary actinomycosis in smokers with poor dental hygiene, but also that actinomycosis may mimic the malignancy process in various anatomical sites. Bacterial cultures and pathology are the cornerstone of diagnosis, but particular conditions are required in order to get the correct diagnosis. Prolonged bacterial cultures in anaerobic conditions are necessary to identify the bacterium and typical microscopic findings include necrosis with

    Aim: To evaluate the efficacy of Ultrasonography compared to clinical diagnosis, radiography and histopathological findings in the diagnosis of maxillofacial swellings. Material and methods: The study was conducted on forty-five patients with maxillofacial swellings. The clinical diagnosis, radiographic diagnosis and ultrasonographic diagnosis were made which was compared to the histopathological diagnosis. The maxillofacial swellings included cystic lesions, benign swellings, malignant swellings, lymphadenopathies and abscesses and space infections. Results: The diagnostic accuracy and contingency coefficient was evaluated considering histopathology as gold standard. The diagnostic accuracy of ultrasound was found to be 92.30% in the diagnosis of cystic lesions, 87.5% in benign tumors, 81.8% in malignant tumors, 100% in lymphadenopathies and 90% in space infections and abscesses. The contingency coefficient of 0.934 was obtained when ultrasonography was compared to the histopathology, which was highly significant. Similar significant results were obtained comparing ultrasonography with clinical diagnosis (0.895) and radiographic diagnosis (0.889). Conclusion: Ultrasonography provides accurate imaging of the head and neck region and provides information about the nature of the lesion, its extent, and relationship with the surrounding structures. As the conventional and digital radiography enable the diagnosis of the presence of the disease, but do not give any indication of its nature. So, together with clinical and histopathological examinations, real time ultrasound imaging works out as a valuable adjunct in the diagnosis of orofacial swellings.

    AIM: To evaluate 20 adults with intussusception and to clarify the cause, clinical features, diagnosis, and management of this uncommon entity.METHODS: A retrospective review of patients aged >18 years with a diagnosis of intestinal intussusception between 2000 and 2008. Patients with rectal prolapse,prolapse of or around an ostomy and gastroenterostomy intussusception were excluded.RESULTS: There were 20 cases of adult intussusception.Mean age was 47.7 years. Abdominal pain, nausea,and vomiting were the most common symptoms. The majority of intussusceptions were in the small intestine (85%). There were three (15%) cases of colonic intussusception. Enteric intussusception consisted of five jejunojejunal cases, nine ileoileal, and four cases of ileocecal invagination. Among enteric intussusceptions,14 were secondary to a benign process, and in one of these, the malignant cause was secondary to metastatic lung adenocarcinoma. All colonic lesions were malignant. All cases were treated surgically.

    2016-05-01

    IgE-mediated allergy to wheat proteins can be caused by exposure through ingestion, inhalation, or skin/mucosal contact, and can affect various populations and age groups. Respiratory allergy to wheat proteins is commonly observed in adult patients occupationally exposed to flour, whereas wheat food allergy is more common in children. Wheat allergy is of growing importance for patients with recurrent anaphylaxis, especially when exercise related. The diagnosis of wheat allergy relies on a consistent clinical history, skin prick testing with well-characterized extracts and specific IgE tests. The accuracy of wheat allergy diagnosis may be improved by measuring IgE responses to several wheat components. However, a high degree of heterogeneity has been found in the recognition pattern of allergens among patient groups with different clinical profiles, as well as within each group. Thus, oral provocation with wheat or the implicated cereal is the reference test for the definitive diagnosis of ingested wheat/cereal allergy. PMID:26800201

    2015-10-01

    Current global economic crisis imposes healthcare system to reduce unnecessary investigations and increase early detection of tumors, to decrease the costs of an advanced disease. Several diagnostic pitfalls may occur dealing with bladder cancer (BC), particularly in nonmuscle-invasive (NMIBC) one. Hematuria, the commonest sign in NMIBC, is often underestimated. Urinary cytology is highly specific for high-grade tumors, but has a low sensitivity for low-grade BC, is operator dependent, and not always obtainable in clinical practice. Numerous urinary tests are available to ameliorate the accuracy of cytology, but none of them is routinly used in urological practice. Ultrasound could hardly detect a small bladder tumor, especially if located in the bladder neck or in the anterior wall. Computed tomography (CT) is widely adopted as an alternative to conventional urography, but its usefulness in patients with hematuria is still debated. MRI has a higher accuracy than CT for staging BC and evaluate the bladder-wall invasion. A negative cystoscopy cannot exclude Tis and should be accompanied by urinary cytology in patients with suspected Tis or high-risk NMIBC; however, new techniques such as narrow band imaging (NBI) and photodynamic (PDD) increase the detection rate of BC and flat lesions. Nearly half of all diagnostic resections present omission of muscle in the specimen or its mention in the pathology report, which is associated with an increased mortality. An adequate muscle sampling during endoscopic resection is mandatory, particularly in patients with high-grade disease. Recognition of pitfalls in diagnosis and management of BC represents the first step for a correct approach. PMID:26481718

    Full Text Available Abstract: Personality disorders represent psychopathological conditions hard to be diagnosed. The Author highlights the clinical aspects of personality disorder diagnosis according to the criteria of the DSM-5. In this study, some of the numerous definitions of personality are mentioned; afterwards, some of the theories on the development of personality shall be. Later on, concepts of temperament, character and personality get analysed. Then, the current approach to personality disorders according to the two models of DSM-5 is reported. The first model is included in the Section II of DSM-5; while in the Section III there exists a proposal for a so-called alternate model. The first one suggests a qualitative or categorical kind of approach to personality disorders, whereas the alternate model proposes a dimensional or quantitative kind of approach and aims to formulate, as well as a diagnosis for general alterations of the personological functioning, even a trait-based personality disorder diagnosis, which can be formulated when a personality disorder is there but doesn't fit criteria for a specific disorder. Ultimately, it can be so claimed: 1 diagnostic criteria of the first model are similar to those of DSM-IV with its respective strenghts and weaknesses, and namely high probability in diagnosis, where  there, of personality disorder, yet insufficient sensitivity in the specification of the disorder; 2 the alternate model, despite criticism, thanks to the possibility of delivering a trait-based personality disorder diagnosis, seems to be more equipped both in the identification of the personality disorder and further specifications.

    Leukodystrophies (LD) and genetic leukoencephalopathies (gLE) are disorders that result in white matter abnormalities in the central nervous system (CNS). Magnetic resonance (MR) imaging (MRI) has dramatically improved and systematized the diagnosis of LDs and gLEs, and in combination with specific clinical features, such as Addison's disease in Adrenoleukodystrophy or hypodontia in Pol-III related or 4H leukodystrophy, can often resolve a case with a minimum of testing. The diagnostic odyssey for the majority LD and gLE patients, however, remains extensive – many patients will wait nearly a decade for a definitive diagnosis and at least half will remain unresolved. The combination of MRI, careful clinical evaluation and next generation genetic sequencing holds promise for both expediting the diagnostic process and dramatically reducing the number of unresolved cases. Here we present a workflow detailing the Global Leukodystrophy Initiative (GLIA) consensus recommendations for an approach to clinical diagnosis, including salient clinical features suggesting a specific diagnosis, neuroim-aging features and molecular genetic testing. We also discuss recommendations on the use of broad-spectrum next-generation sequencing in instances of ambiguous MRI or clinical findings. We conclude with a proposal for systematic trials of genome-wide agnostic testing as a first line diagnostic in LDs and gLEs given the increasing number of genes associated with these disorders.

  13. A Study on the Clinical Diagnosis of Hyperthyroidism

    International Nuclear Information System (INIS)

    To attain a simple and reliable method of evaluating the thyroid function the reliability of the clinical manifestation and the conventional thyroid function tests in diagnosing the hyperthyroidism was studied. The subjects included 184 patients with hyperthyroidism and 66 cases with euthyroidism, who were treated at the Thyroid Clinic, Seoul National University Hospital, from July 1971 through August 1972. The observed results were as follows: l. In the cases of hyperthyroidism, 19% of the patients were male and 81% female; in the cases of euthyroidism, 7. 6% of the patients were male and 92. 4% female. The majority of the patients were in 2nd to 4th decades of their lives. 2. There were objective signs clearly manifested in hyperthyroidism which were rare or absent in the euthyroid state. These clinical signs included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor, and warm skin. In the hyperthyroid state 91. 3% of the cases manifested two or more of the above signs, whereas in the euthyroid state no patients manifested any two of the above signs. 3. The most frequent complaints of the patients with thyroid disease were palpitation, weight low, increased appetite, heat intolerance, perspiration, hunger feeling; nervousness, exertional dyapnea, etc. There was no clear difference in the incidence of the symptoms between hyperthyroidism and euthyroidism. 4. In the diagnosis of hyperthyroidism, the reliability of thyroid function tests was as follows: T7 was 92. 4% reliable, 125IT3 resin uptake rate 91. 6% reliable, 131I thyroid uptake rate in 24 hrs. 89. 4% reliable, serum T4 level 85. 9% reliable and BMR 75. 5% reliable. Therefore the careful observation of the clinical manifestation of the disease is a simple and reliable way of making a correct diagnosis of either hyperthyroidism or euthymidism. 5. In hyperthyroidism there shows no correlationship between the results of the thyroid function test and clinical signs but a high BMR was

    A 9-year-old boy presented to our outpatient specialized sport and exercise medicine clinic complaining of a subacute onset of unilateral knee pain, after an increased level of soccer training. His knee examination was unremarkable. However, he demonstrated significant tenderness on palpation of his ipsilateral hip flexor and adductor tendons. Abnormalities in muscle tone and difficulty in relaxing and resisting the examiner properly were noted and lead to a complete neurological examination. It demonstrated multiple abnormalities such as increased tone and deep tendon reflexes, greater in lower than upper extremities, and abnormal patterning. A mild form of spastic diplegia was suspected and the patient was referred to a pediatric neurologist who confirmed our initial diagnosis. This case draws attention to the importance of maintaining a high level of suspicion for milder forms of diseases that can go unnoticed for years. PMID:25831409

    2002-11-01

    The aim of the study was retrospectively to evaluate the spectrum of chest diseases in patients presenting with clinical suspicion of thoracic aortic dissection in the emergency department. We performed a retrospective medical records review of 86 men and 44 women (ages ranging between 23 and 106 years) with clinically suspected aortic dissection, for CT scan findings and final clinical diagnoses dating between January 1996 and September 2001. All images were obtained by using a standard protocol for aortic dissection. We found aortic dissection in 32 patients (24.6%), 22 of which were Stanford classification type A and 10 Stanford type B. In 70 patients (53.9%), chest pain could not be explained by the CT scan findings. However, in 28 patients (21.5%), CT scanning did reveal an alternate diagnosis that, along with the clinical impression, probably explained the patients' presenting symptoms, including: hiatal hernia (7), pneumonia (5), intrathoracic mass (4), pericardial effusion/hemopericardium (3), esophageal mass/rupture (2), aortic aneurysm without dissection (2), pulmonary embolism (2), pleural effusion (1), aortic rupture (1), and pancreatitis (1). In cases where there is clinical suspicion of aortic dissection, CT scan findings of an alternate diagnosis for the presenting symptoms are only slightly less common than the finding of aortic dissection itself. Although the spectrum of findings will vary depending upon your patient population, beware the alternate diagnosis. PMID:15290550

    We report a patient who presented with clinical and MRI findings suggestive of polymyositis but, in whom, muscle biopsy disclosed a strikingly different diagnosis. A 65-year-old woman presented with 3-week history of bilateral proximal muscle pain and weakness. Laboratory investigations showed markedly elevated inflammatory markers and mildly elevated muscle enzymes. MRI scans of lower limbs showed features suggestive of polymyositis. However, muscle biopsy showed features of a polyarteritis-type vasculitis affecting an intramuscular blood vessel. Our reports highlight the critical role of muscle biopsy in establishing the correct diagnosis in patients with suspected myositis.

  17. Novel electrophysiological approaches to clinical epilepsy. Diagnosis and treatment

    International Nuclear Information System (INIS)

    Seizure onset zone (SOZ) is currently defined by ictal epileptiform discharges, which are most commonly recorded as regional low-voltage fast waves or repetitive spikes. Interictal epileptiform discharges, on the other hand, are not specific enough for SOZ as they are recorded at zones other than the SOZ; they are also recorded from areas that do not generate the ictal pattern and from areas to which ictal discharges propagate. Besides spikes and sharp waves, a novel index of human epileptogenicity has been investigated in association with wide-band electroencephalography (EEG) analysis. We primarily noted the following during clinical neurophysiological analysis for clinical epilepsy. Recent development of digital EEG technology enabled us to record wide-band EEG in a clinical setting. Thus, high frequency (>200 Hz) and low frequency (<1 Hz) components can be reliably recorded using subdural electrodes. Direct current shift, slow shift, ripple, and fast ripple can be well delineated, and they will be potentially useful in the diagnosis and management of epileptic patients. Fiber tractography (morphological parameter) and cortico-cortical-evoked potentials with single cortical stimulation (electrophysiological parameter) elucidated cortico-cortical connections in human brain. The data thus obtained can help us understand the mechanism of seizure propagation and normal cortical functional connectivity. Non-invasive simultaneous recording of EEG and functional magnetic resonance imaging (fMRI) provided information on the roles of deep brain structures associated with scalp-recorded epileptiform discharges. Interventional neurophysiology can shed light on the non-pharmacological treatment of epilepsy. In this report, we discuss these novel electrophysiological approaches to the diagnosis and treatment of clinical epilepsy. (author)

  18. Acute disseminated encephalomyelitis in children: differential diagnosis from multiple sclerosis on the basis of clinical course

    Full Text Available Acute disseminated encephalomyelitis (ADEM is a demyelinating disease of the central nervous system (CNS that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalopathy. ADEM is considered an autoimmune disorder that is triggered by an environmental stimulus in genetically susceptible individuals. The diagnosis of ADEM is based on clinical and radiological features. Most children with ADEM initially present with fever, meningeal signs, and acute encephalopathy. The level of consciousness ranges from lethargy to frank coma. Deep and subcortical white-matter lesions and gray-matter lesions such as thalami and basal ganglia on magnetic resonance imaging (MRI are associated with ADEM. In a child who presents with signs of encephalitis, bacterial and viral meningitis or encephalitis must be ruled out. Sequential MRI is required to confirm the diagnosis of ADEM, as relapses with the appearance of new lesions on MRI may suggest either multiphasic ADEM or multiple sclerosis (MS. Pediatric MS, defined as onset of MS before the age of 16, is being increasingly recognized. MS is characterized by recurrent episodes of demyelination in the CNS separated in space and time. The McDonald criteria for diagnosis of MS include evidence from MRI and allow the clinician to make a diagnosis of clinically definite MS on the basis of the interval preceding the development of new white matter lesions, even in the absence of new clinical findings. The most important alternative diagnosis to MS is ADEM. At the initial presentation, the 2 disorders cannot be distinguished with certainty. Therefore, prolonged follow-up is needed to establish a diagnosis.

  19. Acute kidney injury: from clinical to molecular diagnosis.

    2016-01-01

    The RIFLE classification was introduced in 2004 to describe the presence of acute kidney injury (AKI) and to define its clinical stage, based upon the serum creatinine level and urine output. The same criteria, although slightly modified, are used in the other scoring systems AKIN and KDIGO. Mortality and morbidity remain high in AKI, suggesting that current diagnostic methods are suboptimal, poorly accurate, and often timely inadequate in detecting the presence of early kidney injury. Conversely, a growing body of evidence indicates that new AKI biomarkers can be used to both rule out AKI and to assess high-risk conditions or the presence of subclinical forms. Neutrophil gelatinase-associated lipocalin or cell cycle arrest biomarkers seem to be sensitive and specific enough to be used in conjunction with existing markers of AKI for better classifying renal injury as well as dysfunction. Improvements in diagnosis, risk identification, stratification, prognosis, and therapeutic monitoring may improve prevention and protection from organ damage and help to identify patients at risk, allowing individualized therapy. In this view, we may say that AKI diagnosis has finally moved from clinical to molecular level with potential benefits for the patients because similar progress has been shown in other disciplines.

    Full Text Available Objective To establish and optimize the procedures of fluorescence in situ hybridization(FISH), and evaluate its clinical value in rapid prenatal diagnosis of fetal numerical abnormality of chromosomes 21, 18, 13, X, Y. Methods Amniotic fluid or fetal blood was sampled by routine invasive procedures. After the amniotic fluid cells or fetal blood cells were separated and sequentially processed with hypotonic solution, fixation solution, smear and high temperature, they were hybridized in situ with two panels of specific fluorescence probes to detect numerical abnormality of chromosomes 21, 18, 13, X, Y. All the samples were also cultured and analyzed for their karyotype by conventional methods. Results When it was used as a diagnostic criterion of chromosomal number that the fluorescence signals were observed in ≥90% cells, GLP 13/GLP 21 probe panel showed 2 green/2 red fluorescence signals and CSP18/CSP X/CSP Y probe panel showed 2 blue/2 yellow (female or 2 blue/1 yellow/1 red fluorescence signals (male under normal condition. The test reports of all 196 cases were sent out in 72-96 hours, and 7 cases of Down syndrome, 2 cases of trisomy 18 and 1 case of sex chromosomal numerical abnormality were detected, which were accordant with karyotype analysis results reported one month later. Conclusions FISH has potential for clinical application, and is applicable to rapid prenatal diagnosis of fetal numerical abnormality of chromosomes 21, 18, 13, X, Y. The rapid FISH, together with conventional karyotyping, offer a valuable means for prenatal diagnosis of fetal aneuploidies.

    Magistroni, Riccardo; Izzi, Claudia; Scolari, Francesco

    2016-01-01

    Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic disorder related to kidney. ADPKD is usually easy to diagnose in people who have a family history of ADPKDs developing typical symptoms, including flank, abdominal pain or macroscopic hematuria. In this setting, diagnosis in adults at risk for ADPKD is commonly performed by ultrasonography, which reveals two enlarged kidneys with multiple bilateral cysts. ADPKD may be more difficult to diagnose in the absence of family history or in subjects with atypical presentation, including asymmetric or focal renal imaging findings, discordant disease within family, early onset of ADPKD and development of ESRD before 30 yr of age. The presence of a total of three or more renal cysts for at-risk subjects aged 15-39 years and two cysts or more in each kidney for at-risk subjects aged 40-59 years are sufficient for the diagnosis of ADPKD. The absence of any renal cyst is sufficient for disease exclusion only for at-risk subjects aged 40 years or older. If the family history is negative, the diagnosis of ADPKD can be made in a patient with enlarged kidneys, numerous cysts, presence of liver cysts and absence of findings suggesting a different cystic disease. If the imaging diagnosis is not clear or showing atypical manifestations in subjects, molecular genetic testing should be performed. PMID:27067212

    Full Text Available Background: Mitochondrial diseases are caused by mutations in mitochondrial or nuclear genes, or both and most patients do not present with easily recognizable disorders. The characteristic morphologic change in muscle biopsy, ragged-red fibers (RRFs provides an important clue to the diagnosis. Materials and Methods: Demographic data, presenting symptoms, neurological features, and investigative findings in 60 patients with ragged-red fibers (RRFs on muscle biopsy, seen between January 1990 and December 2002, were analyzed. The authors applied the modified respiratory chain (RC diagnostic criteria retrospectively to determine the number of cases fulfilling the diagnostic criteria of mitochondrial disease. Results: The most common clinical syndrome associated with RRFs on muscle biopsy was progressive external ophthalmoplegia (PEO with or without other signs, in 38 (63% patients. Twenty-six patients (43% had only external ophthalmoplegia, 5 (8% patients presented with encephalomyopathy. Specific syndromes were the presenting feature in 8 (13%, Kearns-Sayre syndrome (KSS in 4 and myoclonus epilepsy with ragged-red fibers (MERRF in 4. Myopathy was the presenting feature in 5 (8% and 4 presented with infantile myopathy. Of the 60 patients, 18 (30% had proximal muscle weakness. Two patients with KSS and one patient with myopathy had complete heart block necessitating pace making. When the modified RC diagnostic criteria were applied, only 26 (43% patients had one other major criterion in addition to RRFs for the diagnosis of mitochondrial diseases. The remaining 34 (57% patients with RRFs on muscle biopsy had only some clinical features suggestive of RC disorder but did not fulfill the clinical criteria (of the modified diagnostic criteria for the diagnosis of mitochondrial diseases. Conclusion: In patients with clinical features suggestive of RC disorder, demonstration of RRFs on muscle biopsy helps in confirming the diagnosis of mitochondrial

    Background Turner syndrome (TS) is a common genetic disorder caused by abnormalities of the X chromosome. We aimed to describe the phenotypic characteristics of TS patients and evaluate their association with presenting clinical characteristics and time at diagnosis. Methods We studied females diagnosed with TS at King Abdul Aziz Medical City (KAMC), Riyadh between 1983 and 2010. Patients were classified based upon karyotype into females with classical monosomy 45,X (group A) and females with other X chromosome abnormalities (mosaic 45,X/46,XX, Xqisochromosomes, Xp or Xq deletion) (group B). Clinical features of the two groups were analyzed. Results Of the 52 patients included in the study, 16(30.8%) were diagnosed with classical monosomy 45,X and the rest with other X chromosome abnormalities. Only 19(36.5%) patients were diagnosed in infancy and the remaining during childhood or later (odds ratio (OR) = 4.5,95%CI 1.27–15.90, p=0.02). Short stature was universal in group A versus 77.8% in group B. All patients in group A had primary amenorrhea compared with 63.2% of those in group B (P = 0.04); the rest of group B had secondary amenorrhea. Cardiovascular abnormalities were higher in group A (OR=3.50, 95%CI 0.99–12.29, p-value =0.05). Renal defects and recurrent otitis media were similar in both groups. Conclusion This study suggests that karyotype variations might affect the phenotype of TS; however, it may not reliably predict the clinical presentation. Chromosomal analysis for all suspected cases of TS should be promptly done at childhood in order to design an appropriate management plan early in life. PMID:25246887

    Full Text Available Celiac disease is a clinically heterogeneous disease characterized by an inadequate immunological response when patients with specific genetic phenotypes are exposed to gluten. This article presents a case of a young woman diagnosed in Gastroenterology Department of “ St. Andrew Apostle” Emergency Hospital of Constanta with celiac disease after multiple admissions into the hospital for unspecific symptoms such as pallor, fatigue, pirosis, weight loss and 1-2 soft stools/day. The history with period irregularities and infertility without a known cause, a recent unexplained bone fracture, the muscle weakness, neuropsychiatric symptoms characterized by sleep disturbances and irritability correlated with the biological features characterized by moderate feriprive anemia, Ca and Mg decreased level, thyroid autoimmune impairment and gastrointestinal symptoms raised the suspicion of an autoimmune disorder with multiple targets. The videcapsule endoscopy (VCE revealed the specific pattern of the celiac disease: villous atrophy of jejunum, scalloping, absent folds and cobblestone mucosal pattern. Results were correlated with immunology tests results. The patient was transferred on a gluten free diet and the clinical and VCE controlsrevealed the healing of the jejunum mucosa. The VCE can be the tool for positive diagnosis of an unusual and heterogeneous celiac disease in patients with various symptoms without an apparent cause.

  8. Current approach to masked hypertension: From diagnosis to clinical management.

    LENUS (Irish Health Repository)

    Dolan, Eamon

    2013-11-28

    The term masked hypertension phenomenon was first described by the late Professor Thomas Pickering and is commonly defined as having a normal clinic blood pressure (BP) but an elevated "out of office" reading. In the main these elevated readings have been provided through ambulatory blood pressure monitoring (ABPM) but sometimes home BP monitoring is used. It is now largely accepted that ABPM gives a better classification of risk than clinic BP. Thus the elevated ABPM levels should relate to higher cardiovascular risk and it follows that these people might be regarded as being genuinely hypertensive and at higher cardiovascular risk. The problem for clinical practice is how to identify and manage these subjects. The phenomenon should be suspected in subjects who have had an elevated clinic BP at some time, in young subjects with normal or normal-high clinic BP who have early left ventricular hypertrophy, in subjects with a family history of hypertension in both parents, patients with multiple risks for cardiovascular disease and perhaps diabetic patients. It appears to be more prevalent in subjects of male gender, with younger age, higher heart rate, obesity or high cholesterol levels and in smokers. Those with masked hypertension are at higher risk of events such as stroke and have a higher prevalence of target organ damage, for example, nephropathy. In conclusion most of the debate around this topic relates to its reliable identification. Given the higher ambulatory readings there is an increases cardiovascular risk making this diagnosis important. This article is protected by copyright. All rights reserved.

    2010-10-01

    Full Text Available Abstract Objectives The aim of the study was to determine if differences in clinical diagnosis versus autopsy findings concerning the cause of death in polytrauma fatalities would be detected in 19 cases of fatal polytrauma from a Level 1 trauma centre. Methods Clinical diagnoses determining the cause of death in 19 cases of fatal polytrauma (2007 - 2008 from a Level 1 trauma centre were correlated with autopsy findings. Results In 13 cases (68%, the clinical cause of death and the cause of death as determined by autopsy were congruent. Marginal differences occurred in three (16% patients while obvious differences in interpreting the cause of death were found in another three (16% cases. Five fatalities (three with obvious differences and two with marginal differences were remarked as early death (1-4 h after trauma and one fatality with marginal differences as late death (>1 week after trauma. Obvious and marginal discrepancies mostly occurred in the early phase of treatment, especially when severely injured patients were admitted to the emergency room undergoing continued cardiopulmonary resuscitation, i. e. limiting diagnostic procedures, and thus the clinical cause of death was essentially determined by basic emergency diagnostics. Conclusions Autopsy as golden standard to define the cause of death in fatal polytrauma varies from the clinical point of view, depending on the patient's pre-existing condition, mechanism of polytrauma, necessity of traumatic cardiopulmonary resuscitation, survival time, and thus the possibility to perform emergency diagnostics. An autopsy should be performed at least in cases of early fatal polytrauma to help establishing the definite cause of death. Moreover, autopsy data should be included in trauma registries as a quality assessment tool.

The available literature has been reviewed for motor, cognitive, and psychiatric alterations, which are the three major symptom domains of this devastating progressive disease. From a clinical point of view, one has to be aware that the HD phenotype can vary highly across individuals and during the course of the disease. Also, symptoms in juvenile HD can differ substantially from those with adult-onset of HD. Although there is no cure of HD and management is limited, motor and psychiatric symptoms often respond to pharmacotherapy, and nonpharmacological approaches as well as supportive care are essential. International treatment recommendations based on study results, critical statements, and expert opinions have been included. This review is restricted to symptomatic and supportive approaches since all attempts to establish a cure for the disease or modifying therapies have failed so far.

  11. Feline asthma syndrome: a retrospective study of the clinical presentation in 29 cats

    International Nuclear Information System (INIS)

    Feline asthma syndrome (FAS) is a clinical condition characterised by recurrent bouts of coughing, wheezing and, or, dyspnoea. While the aetiology is unproven, the condition is believed to involve a type I immediate hypersensitivity reaction to inhaled allergens. In this paper the clinical data from 29 cats, where a diagnosis of FAS was made, are assessed retrospectively. The most common clinical presentation was recurrent bouts of coughing (n = 26) and dyspnoea (n = 21). Radiographic changes were noted in 24 cats, which included increased bronchial (n = 5), interstitial (n = 7) and mixed (n = 12) (bronchial and interstitial) patterns. Right middle lung lobe collapse was noted in two cats. Abnormal bronchial cytology was present in 16 cats. A predominant eosinophilic sample was collected in only three cats. There were minimal changes in differential white cell counts, and mild eosinophilia was found in only five cats. Prednisolone alone was the most effective therapy, although avoidance of putative aeroallergens and antibacterial therapy was effective in some. On the basis of the data from these cases it would appear that the diagnosis of FAS depends largely on the clinical presentation and radiographic findings. The value of ancillary tests in the diagnosis of FAS appears to be limited

    International Nuclear Information System (INIS)

    A survey was conducted in the urban area of Lages using patients who had been submitted to a computed tomography of the skull in the period of March-December, 1996, for different reasons. Forty-two patients with a provisional diagnosis of neurocysticercosis, and 57 negatives were personally interviewed by one of the authors (Pfuetzenreiter), using a semi-structured procedure. More individuals with a provisional diagnostic of neurocysticercosis reported clinical manifestations related to this infection than those found negative. this difference is more marked among women, except in relation to convulsions, more frequently reported by men (19.05%) than by women (7.14%). The greater percentage of inactive forms (83.33%0 and a longer history of perceived symptoms among those positives suggest that the condition is not new. (author)

    Full Text Available Baló's Concentric sclerosis (BCS is a rare demyelinating disease considered to be a variant of multiple sclerosis (MS. The typical magnetic resonance imaging (MRI changes associated with BCS consist of concentric rings or onions' cross-section on T1-weighted (T1W images. Because MRI reveals pathological changes consistent with autopsy in the focus of BCS, it plays an important role in the before-death diagnosis of BCS. We report three cases of BCS diagnosed antemortem on the basis of the typical concentric rings pattern on MRI and on the basis of clinical findings and cerebrospinal fluid (CSF examination. BCS often occurs in the prime of life, acutely or subacutely. Then come cerebral multifocal symptoms and signs. We find that BCS is not always an acute and irreversible pathological process as described in the past.

    Full Text Available Non-invasive real-time observations and the evaluation of living cell conditions and functions are increasingly demanded in life sciences. Surface plasmon resonance (SPR sensors detect the refractive index (RI changes on the surface of sensor chips in label-free and on a real-time basis. Using SPR sensors, we and other groups have developed techniques to evaluate living cells’ reactions in response to stimuli without any labeling in a real-time manner. The SPR imaging (SPRI system for living cells may visualize single cell reactions and has the potential to expand application of SPR cell sensing for clinical diagnosis, such as multi-array cell diagnostic systems and detection of malignant cells among normal cells in combination with rapid cell isolation techniques.

    2016-01-01

    Mastocytosis is a term used to describe a heterogeneous group of disorders characterized by clonal proliferation of mast cells in various organs. The organ most often affected is the skin. Mastocytosis is a relatively rare disorder that affects both sexes equally. It can occur at any age, although it tends to appear in the first decade of life, or later, between the second and fifth decades. Our understanding of the pathophysiology of mastocytosis has improved greatly in recent years, with the discovery that somatic c-kit mutations and aberrant immunophenotypic features have an important role. The clinical manifestations of mastocytosis are diverse, and skin lesions are the key to diagnosis in most patients. PMID:26546030

    Background The brain death confirmation tests occupy a different position in each country's diagnostic criteria (or guideline); the choices of tests are also different.China brain death criteria include clinical judgment and confirmation tests.This study aimed to confirm the preferred confirmatory test and complementary confirmatory tests.Methods We did a clinical brain death determination on deep coma patients,and then divided them into brain death group and non-brain death group.According to the Chinese standards for determining brain death,both the groups accepted confirmatory tests including electroencephalograph (EEG),somatosensory evoked potentials (SEP),and transcranial Doppler (TCD).The sensitivity,specificity,false positive rate,and false negative rate were calculated to evaluate the accuracy of the confirmatory tests.Results Among the 131 cases of patients,103 patients met the clinical criteria of brain death.Respiratory arrest provocation test was performed on 44 cases and 32 cases (73%) successfully completed and confirmed that they have no spontaneous breathing.Of the three confirmation tests,EEG had the highest completion rate (98%) and good sensitivity (83%) and specificity (97%); TCD had followed completion rate (54%) and not good sensitivity (73%) and specificity (75%); SEP had the lowest completion rate (49%),good sensitivity (100%),and not good specificity (78%).After the combination of SEP or TCD with EEG,the specificity can increase to 100%.Conclusions The completion rate of respiratory arrest provocation test remains a problem in the clinical diagnosis of brain death.If the test cannot be completed,whether to increase a confirmatory test is debatable.SEP had an ideal sensitivity,and the specificity will reach 100% after combining with TCD or EEG.When a confirmed test was uncertain,we suggest increasing another confirmatory test.

    Abstract Introduction Penile fracture is an uncommon urologic emergency, and is the traumatic rupture of the tunica albuginea covering the corpus cavernosa. This usually occurs following blunt trauma sustained during coitus, masturbation or self-manipulations to hide or suppress an erection. Clinical diagnosis can often be easily made with typical history and examination findings. However, the patient may present atypically and/or with a suspicion of associated urethral injury. The roles of v...

    Background.  Hansen's disease (HD), or leprosy, is uncommon in the United States. We sought to describe the characteristics of patients with HD in a US clinic, including an assessment of delays in diagnosis and HD reactions, which have both been associated with nerve damage. Methods.  A retrospective chart review was conducted on patients seen at an HD clinic in the southern United States between January 1, 2002 and January 31, 2014. Demographic and clinical characteristics were summarized, including delays in diagnosis, frequency of reactions, and other complications including peripheral neuropathy. Results.  Thirty patients were seen during the study time period. The majority of patients were male (73%) and had multibacillary disease (70%). Brazil, Mexico, and the United States were the most frequent of the 14 countries of origin. Hansen's disease "reactions", severe inflammatory complications, were identified among 75% of patients, and nerve damage was present at diagnosis in 36% of patients. The median length of time between symptom onset and diagnosis was long at 12 months (range, 1-96), but no single factor was associated with a delay in diagnosis. Conclusions.  The diagnosis of HD was frequently delayed among patients referred to our US clinic. The high frequency of reactions and neuropathy at diagnosis suggests that further efforts at timely diagnosis and management of this often unrecognized disease is needed to prevent the long-term sequelae associated with irreversible nerve damage.

    Background Glomus tumors are relatively uncommon subcentimeteric benign perivascular neoplasms usually located on the fingers. With their blue-red color and common subungual location, they are commonly confused for vascular or melanocytic lesions. To date there is no comprehensive review of an institutional experience with glomus tumors. Methods A 14-year retrospective review of all cases within University of California, Los Angeles, with either a clinical or pathological diagnosis of glomus tumor was performed. Data obtained included demographic information, tumor description, pathological diagnoses, immunohistochemical studies, radiographic and treatment information, and clinical course. Rates of concordance between clinical and pathological diagnoses and an evaluation of overlap with other entities were assessed. Results Clinical diagnosis of glomus tumor showed concordance with a histopathological diagnosis (45.4% of cases). The most common alternate clinical diagnoses included lipoma, cyst, or angioma. A pathological diagnosis of glomus tumor was most common in the fourth to seventh decades of life. The most common presentation was a subcentimeter lesion on the digit. Deep-seated tumors had a strikingly increased risk for malignancy (33%). Radiological studies were not relied on frequently (18.2% of cases). Immunohistochemical analysis showed diffuse αSMA and MSA expression in nearly all cases (99% and 95%, respectively), with focal to diffuse CD34 immunostaining in 32% of cases. Discussion Our study illustrates trends in the clinical versus pathologic diagnoses of glomus tumor, common competing diagnoses, a difference in demographics than is commonly reported (older age groups most commonly affected), and important differences in the use adjunctive diagnostic tools including radiology and immunohistochemistry.

Methods: One hundred seventy-one patients with diabetes mellitus admitted between September 1, 2006, and June 30, 2008, to the labor room at Maternity Hospital in Kuwait for induction of labor made up the study population; while an equivalent number of patients without medical complications who also were admitted for induction of labor made up the control group. The patients were assessed at admission, and their medical data were extracted. The study and control patients were monitored through labor/puerperium, and the outcome was documented. Results: Gestational diabetes mellitus was diagnosed in 71.9% of the study patients, a past history of diabetes mellitus was recorded in 81.34% of the study patients, and 49.2% of the patients were admitted at 8–12 weeks of gestation for diabetic control. The mean weight gained in pregnancy was significantly higher for control patients (11.52±5.643 versus [vs] 9.90±5.757 kg/m2; P<0.009, and the body mass index of study patients was higher (32.00±6.160 vs 28.20±5.885 kg/m2; P<0.0001. Of the study population, 64.3% of the patients were managed with diet and increased physical activity and 35.7% with insulin, diet, and increased physical activity. The incidences of maternal morbidity in both study and control groups were comparable, and the incidence of preeclampsia was low, at 2.3%. The gestational age at delivery was higher in the control group (39.02±1.834 weeks vs 38.62±1.773 weeks; P<0.0001, and the percentage of cesarean deliveries was higher in the study population (44.4% vs 33.3%; P=0.046. The Apgar scores of the both groups were comparable and in the normal range, and the

    Automatic Speech Signal Analysis for Clinical Diagnosis and Assessment of Speech Disorders provides a survey of methods designed to aid clinicians in the diagnosis and monitoring of speech disorders such as dysarthria and dyspraxia, with an emphasis on the signal processing techniques, statistical validity of the results presented in the literature, and the appropriateness of methods that do not require specialized equipment, rigorously controlled recording procedures or highly skilled personnel to interpret results. Such techniques offer the promise of a simple and cost-effective, yet objective, assessment of a range of medical conditions, which would be of great value to clinicians. The ideal scenario would begin with the collection of examples of the clients’ speech, either over the phone or using portable recording devices operated by non-specialist nursing staff. The recordings could then be analyzed initially to aid diagnosis of conditions, and subsequently to monitor the clients’ progress and res...

  9. Clinical application of FDG-PET for cancer diagnosis

    International Nuclear Information System (INIS)

    Positron emission tomography using 18F-FDG is accepted in clinical medicine as an imaging tool for the diagnosis and assessment of a large variety of cancers. Medicare reimbursement for these studies has been accepted in Japan since 2002. The number of requests for FDG-PET examinations has been increasing in institutions where a PET device is installed. PET is considered to be especially effective in re-staging and detecting recurrence of disease. In order to evaluate PET images properly, it is important to be familiar with the various physiological uptake patterns of FDG, and also to be alert to the possibility of false-positive and false-negative findings. Quantitative values obtained in PET images are widely used for the differentiation of benign and malignant tumors and for monitoring treatment; however, it should be kept in mind that these values may be influenced by many factors. To complement the poorer spatial resolution of PET, a combined PET/CT scanner has been created and its clinical application has begun. It is expected that this imaging tool will be useful and have a great effect on patient management. (author)

    Pili torti also known as 'twisted hairs' (Latin: pili=hair; torti=twisted) is a rare, congenital or acquired clinical presentation, in which the hair shaft is flattened at irregular intervals and twisted 180º along its axis. It is clinically characterized by fragile, brittle, coarse and lusterless hairs, due to uneven light reflection on the twisted hair surface. Pili torti may be associated with neurological abnormalities and ectodermal dysplasias. There is no specific treatment for this condition, but it may improve spontaneously after puberty. We report a case of pili torti in a child who presented fragile, brittle, difficult to comb hair. The patient had no comorbidities. PMID:26312667

  12. A diagnosis-based clinical decision rule for spinal pain part 2: review of the literature

    2008-08-01

    Full Text Available Abstract Background Spinal pain is a common and often disabling problem. The research on various treatments for spinal pain has, for the most part, suggested that while several interventions have demonstrated mild to moderate short-term benefit, no single treatment has a major impact on either pain or disability. There is great need for more accurate diagnosis in patients with spinal pain. In a previous paper, the theoretical model of a diagnosis-based clinical decision rule was presented. The approach is designed to provide the clinician with a strategy for arriving at a specific working diagnosis from which treatment decisions can be made. It is based on three questions of diagnosis. In the current paper, the literature on the reliability and validity of the assessment procedures that are included in the diagnosis-based clinical decision rule is presented. Methods The databases of Medline, Cinahl, Embase and MANTIS were searched for studies that evaluated the reliability and validity of clinic-based diagnostic procedures for patients with spinal pain that have relevance for questions 2 (which investigates characteristics of the pain source and 3 (which investigates perpetuating factors of the pain experience. In addition, the reference list of identified papers and authors' libraries were searched. Results A total of 1769 articles were retrieved, of which 138 were deemed relevant. Fifty-one studies related to reliability and 76 related to validity. One study evaluated both reliability and validity. Conclusion Regarding some aspects of the DBCDR, there are a number of studies that allow the clinician to have a reasonable degree of confidence in his or her findings. This is particularly true for centralization signs, neurodynamic signs and psychological perpetuating factors. There are other aspects of the DBCDR in which a lesser degree of confidence is warranted, and in which further research is needed.

    Acute diarrheal infections are a common health problem globally and among both individuals in the United States and traveling to developing world countries. Multiple modalities including antibiotic and non-antibiotic therapies have been used to address these common infections. Information on treatment, prevention, diagnostics, and the consequences of acute diarrhea infection has emerged and helps to inform clinical management. In this ACG Clinical Guideline, the authors present an evidence-based approach to diagnosis, prevention, and treatment of acute diarrhea infection in both US-based and travel settings. PMID:27068718

    The goals of this study were to (1) assess prevalence rates of borderline personality disorder (BPD) in public mental health patients and (2) compare research assessment rates to clinical record rates in those with and without a history of high utilization of inpatient psychiatric hospitalization. One hundred and sixty participants randomly selected from county mental health centers were fully assessed. Among the non-high utilizers, 10% met criteria for BPD on research diagnosis, 4.5% on clinical record diagnosis, and 1.5% on both. Among high utilizers, 42% met criteria for BPD on research diagnosis, 19% on clinical record diagnosis, and 19% on both. For the non-high utilizers, the sensitivity of the clinical record diagnosis (compared to the gold standard of the research diagnosis) was 15% and the specificity was 97%. For the high utilizer group, the sensitivity of the clinical record diagnosis was 45% and specificity was 100% indicating that there was never an incorrect clinical diagnosis of BPD among the high utilizers. Thus, while the specificity of the clinical record was high, the sensitivity of the clinical record diagnosis was quite low, and the clinical record greatly underestimated the prevalence of BPD in this sample. Further, since effective outpatient treatment has been developed for these expensive high utilizers with BPD, the under-recognition of BPD has significant implications for the planning of outpatient mental health services in public sector settings.

  15. Contribution of Transjugular Liver Biopsy in Patients with the Clinical Presentation of Acute Liver Failure

    International Nuclear Information System (INIS)

    Purpose. Acute liver failure (ALF) treated with conservative therapy has a poor prognosis, although individual survival varies greatly. In these patients, the eligibility for liver transplantation must be quickly decided. The aim of this study was to assess the role of transjugular liver biopsy (TJLB) in the management of patients with the clinical presentation of ALF. Methods. Seventeen patients with the clinical presentation of ALF were referred to our institution during a 52 month period. A TJLB was performed using the Cook Quick-Core needle biopsy. Clinical data, procedural complications, and histologic findings were evaluated. Results. Causes of ALF were virus hepatitis B infection in 7 patients, drug toxicity in 4, mushroom in 1, Wilson's disease in 1, and unknown origin in 4. TJLB was technically successful in all patients without procedure-related complications. Tissue specimens were satisfactory for diagnosis in all cases. In 14 of 17 patients the initial clinical diagnosis was confirmed by TJLB; in 3 patients the initial diagnosis was altered by the presence of unknown cirrhosis. Seven patients with necrosis <60% were successfully treated with medical therapy; 6 patients with submassive or massive necrosis (≥85%) were treated with liver transplantation. Four patients died, 3 had cirrhosis, and 1 had submassive necrosis. There was a strict statistical correlation (r = 0.972, p < 0.0001) between the amount of necrosis at the frozen section examination and the necrosis found at routine histologic examination. The average time for TJLB and frozen section examination was 80 min. Conclusion. In patients with the clinical presentation of ALF, submassive or massive liver necrosis and cirrhosis are predictors of poor prognosis. TLJB using an automated device and frozen section examination can be a quick and effective tool in clinical decision-making, especially in deciding patient selection and the best timing for liver transplantation

    2010-01-01

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

    Pertussis is a highly contagious disease caused by the Gram negative aerobic coccobacillus, Bordetella pertussis. It may present with severe symptoms and complications in infants and can pose a diagnostic challenge. This is a vaccine preventable illness covered by the Irish Childhood Immunisation Schedule. In 2011, a retrospective review was conducted of the records of infants, under six months, with a confirmed diagnosis of pertussis, presenting to Temple Street Children's University Hospital (TSCUH). A summery of notifications of pertussis nationally, from 2001 to 2012, was also examined as part of the study. This found that the rate of reported cases of pertussis has been increasing in Ireland. This national increase corresponds with a rising number of cases identified at TSCUH. Patients commonly presented severely ill with cyanosis and apnoea, on a background of prolonged cough. We found that pertussis was diagnosed rapidly in most cases however in all cases there was a delay to commencement of appropriate macrolide therapy. PMID:25226721

    2012-03-01

    Full Text Available Diagnosis and treatment of ectopic ACTH-syndrome currently is one of the most challenging problems among other forms of endogenous hypercorticism. This syndrome is associated with presence of extrapituitary tumors characterized with different histogenesis and localization, which produce adrenocorticotropic hormone (ACTH, or – rarely – corticotrophin-releasing hormone. In most cases the ectopic synthesis of ACTH is performed in bronchial carcinoid tumors (36–46%, oat cell cancer (18–20%, medullary thyroid cancer (3–7%, pheochromocytoma (9–23%, other sites are infrequent (pancreas, thymus, parotid gland, ovaries, uterus, prostate, colon, stomach, esophagus, etc.. Much of these tumors are aggressive and are characterized with propensity to metastasize and relapse. Currently there are few contradictory data on the comparative evaluation of the effectiveness of methods of topical diagnosis of the source of ectopic ACTH-secretion, and therefore there is an urgent need to develop an optimal and most efficient algorithm for diagnostic procedures to determine the extent of the tumor in patients with ectopic ACTH-syndrome. Indications for surgery, timing and extent of surgical intervention, the effectiveness of the operation, the causes and frequency of relapses are still discussed.The present difficulties of diagnosis, as well as the lack of a unified approach to the treatment of this disease in the complex, often lead to the progression and development of a large number of serious complications functions of up to disability, which in turn does not lead to significant improvement of quality of life. Thus further research is necessary to study of this disease

    Acetaminophen or paracetamol, a commonly used over-the-counter analgesic, is known to elicit severe adverse reactions when taken in overdose, chronically at therapeutic dosage or, sporadically, following single assumptions of a therapeutic dose. Damage patterns including liver damage and, rarely, acute tubular necrosis or a fixed drug exanthema. We present a case of fatal acetaminophen toxicity with postmortem blood concentration 78 μg/mL and unusual clinical features, including a visually striking and massive epidermolysis and rhabdomyolysis, disseminated intravascular coagulation and myocardial ischemia. This case is compared with the most similar previous reports in terms of organ damage, clinical presentation, and cause of death. We conclude that a number of severe patterns of adverse effects to acetaminophen are emerging that were previously greatly underestimated, thus questioning the adequacy of the clinical spectrum traditionally associated with acetaminophen intoxication and leading to the need to review this spectrum and the associated diagnostic criteria.

    Full Text Available OBJECTIVE: To assess the utility of clinical features for diagnosis of streptococcal pharyngotonsillitis in pediatrics.METHODS: A total of 335 children aged 1-18 years old and presenting clinical manifestations of acute pharyngotonsillitis (APT were subjected to clinical interviews, physical examinations, and throat swab specimen collection to perform cultures and latex particle agglutination tests (LPATs for group A streptococcus (GAS detection. Signs and symptoms of patients were compared to their throat cultures and LPATs results. A clinical score was designed based on the multivariate logistic regression analysis and also was compared to throat cultures and LPATs results. Positive throat cultures and/or LPATs results were used as a reference standard to establish definitive streptococcal APT diagnosis.RESULTS: 78 children (23.4% showed positivity for GAS in at least one of the two diagnostic tests. Coryza absence (odds ratio [OR]=1.80; p=0.040, conjunctivitis absence (OR=2.47; p=0.029, pharyngeal erythema (OR=3.99; p=0.006, pharyngeal exudate (OR=2.02; p=0.011, and tonsillar swelling (OR=2.60; p=0.007 were significantly associated with streptococcal pharyngotonsilitis. The highest clinical score, characterized by coryza absense, pharyngeal exudate, and pharyngeal erythema had a 45.6% sensitivity, a 74.5% especificity, and a likelihood ratio of 1.79 for streptococcal pharyngotonsilitis.CONCLUSIONS: Clinical presentation should not be used to confirm streptococcal pharyngotonsilitis, because its performance as a diagnostic test is low. Thus, it is necessary to enhance laboratory test availability, especially of LPATs that allow an acurate and fast diagnosis of streptococcal pharyngotonsilitis.

  2. Idiopathic granulomatous mastitis; Clinical presentation, radiological features and treatmant

    International Nuclear Information System (INIS)

    To determine the clinical characteristic, clinical presentations and radiological features of diopathic granulomatous mastitis, and the best treatment approaches of this clinical entity. Between 1996 and 2003 the files and histopathology reports of 25 patients with granulomatous mastitis at King Abdul-Aziz University Hospital Jeddah, Kindom of Saudi Arabia were reviewed. The data were analyzed and a Medline search was carried out from 1970 to 2003 to review relevant cases. The age of patients ranged from 24-66 years and the mean age was 36.6+-9.43 years. All patients were females. The most common clinical presentation was palpable tender mass. The most common mammographic finding was ill-defined mass. However, mixed hypo- and hyper-echogenic lesions with tubular connections were the common ultrasonic findings. Treatment approaches were conservative or surgical excision or steroid. Conservative treatment associated with the higher rate of complications, while treatment with steroid showed complete remission of disease. Idiopathic granulomatous mastitis is a rare, benign breast disease that is usually underestimated or misdiagnosed. The clinical and radiological features resemble those of infectious mastitis or breast carcinoma. Early recognition and initiation of steroid treatment will result in complete remission of the disease and prevent complications. (author)

    Posterior reversible encephalopathy syndrome (PRES) is an obstetric emergency frequently occurring in a pregnant or puerperal woman, manifested with an acute headache, consciousness impairment, seizures, and visual deficits and is associated with white matter changes predominantly affecting the posterior parietal and occipital lobes of the brain. Apart from the above-described typical location of the changes, the most common atypical location involves the brain stem and basal ganglia. Since magnetic resonance imaging (MRI) is more sensitive and specific imaging technique compared to computerized tomography, establishing the diagnosis and follow-up in patients with PRES is based mainly on MRI findings. It is particularly important not to exclude PRES as a possible diagnosis when we have the appropriate clinical presentation accompanied by the atypical radiological findings, since this clinical-radiological syndrome can often be manifested with an atypical MRI image.

    Full Text Available Objective To explore the clinical characteristics and the present status of diagnosis and treatment of chronic cough.Methods The clinical data of 238 in-patients and out-patients of Departments of Respiratory Diseases from 4 teaching hospitals of Chongqing Municipality were collected from Oct.2008 to Dec.2009,and their clinical characteristics,diagnosis and therapeutic effects were retrospectively analyzed.Results A total of 238 patients were enrolled,most of them complained of dry cough and night cough.Throat symptoms were most common,including itching or foreign body sensation,throat discomfort and gastro-oesophageal reflux.Congestion of pharynx and cobblestone like changes in posterior pharyngeal wall were the most common signs in patients with chronic cough.Among all the supplementary examinations,bronchial provocation test resulted in highest positive rate.Etiological diagnosis was done in a total of 254 case-times for diseases leading to chronic cough,among them upper airway cough syndrome(UACS was suspected in 115 case-times.cough variant asthma(CVA in 42 case-times,and cough due to gastroesophageal reflux(GERC in 53 case-times.After the specific treatment targeting UACS,CVA and GERC,in 152 case-times improvement was found after follow-up,including 56,27 and 21 case-times,respectively,with an effective rate of 68.4%(104/152.The final diagnosis for the other 44 case-times with chronic cough was chronic tonsillitis,chronic bronchitis,eosinophilic bronchitis and angiotensin converting enzyme inhibitor(ACEI induced cough.A definite diagnosis was finally made in 148 out of a total of 254 casses,with a diagnostic rate of 58.3%(148/254.Conclusion The final diagnostic rate in etiology of chronic cough is still poor nowadays in our country,and empirical treatment is still the main practice for chronic cough.

  6. Imaging diagnosis in relapsing polychondritis and correlation with clinical and serological data

    International Nuclear Information System (INIS)

    We hypothesize that imaging findings from CT and MRI correlate better with clinical markers for assessment of disease activity in patients with the rare relapsing polychondritis (RPC) than with serological inflammatory markers. Retrospective database search at our institution identified 28 patients (13 females; age 49.0 years ± 15.0 SD) with RP between September 2004 and March 2014. Institutional review board approval was obtained for this retrospective data analysis. All patients had clinically proven RPC with at least two episodes of active disease. Of those, 18 patients were examined with CT- and MRI and presented all morphologic features of RPC like bronchial/laryngeal/auricular cartilage thickness, contrast enhancement, increased T2-signal intensity. Imaging data was subsequently correlated with corresponding clinical symptoms like fever, dyspnea, stridor, uveitis, pain, hearing impairment as well as with acute-phase-inflammatory parameters like C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). The clinical parameters were in good agreement with imaging findings and clinical symptoms such as tracheal wall thickening and dyspnea (r =0.65 p = 0.05), joint synovitis on MRI and a higher McAdam score (r = 0.84 p < 0.001). No correlations were found between inflammatory laboratory markers, imaging findings and clinical features. Imaging diagnosis in RPC using CT and/or MRI delivers information about the degree of disease activity that correlates better with clinical features than unspecific inflammatory laboratory markers. Additionally, clinically unapparent cartilage involvement can be assessed adding value to the clinical diagnosis and therapy planning in this rare disease. (orig.)

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

    2014-02-01

    Cholangiocarcinoma (CCA) is the second most common primary hepatic malignancy worldwide. The incidence of intrahepatic CCA is increasing, whereas that of extrahepatic CCA is decreasing. This review looks at the new advances that have been made in the management of CCA, based on a PubMed and Science Citation Index search of results from randomized controlled trials, reviews, and cohort, prospective and retrospective studies. Aggressive interventional approaches and new histopathological techniques have been developed to make a histological diagnosis in patients with high risk factors or suspected CCA. Resectability of the tumour can now be assessed using multiple radiological imaging studies; the main prognostic factor after surgery is a histologically negative resection margin. Biliary drainage and/or portal vein embolization may be performed before extended radical resection, or liver transplantation may be undertaken in combination with neoadjuvant chemotherapy or chemoradiotherapy. Though many advances have been made in the management of CCA, the standard modality of treatment has not yet been established. This review focuses on the clinical options for different stages of CCA.

    Full Text Available Giant cell arteritis (GCA is a vasculitis affecting mainly large and medium-sized arteries, which the classification of systemic vasculitides refers to as those mainly involving the large vessels. GCA is typified by the involvement of extracranial aortic branches and intracranial vessels, the aorta and its large vessels are being affected most frequently. The paper considers the terminology, classification, prevalence, major pathogenic mechanisms, and morphology of GCA. A broad spectrum of its clinical subtypes is due to target vessel stenosis caused by intimal hyperplasia. In 40% of cases, GCA is shown to be accompanied by polymyalgia rheumatica that may either precede or manifest simultaneously with GCA, or follow this disease. The menacing complications of GCA may be visual loss or ischemic strokes at various sites depending on the location of the occluded vessel. Along with the gold standard verification of the diagnosis of GCA, namely temporal artery biopsy, the author indicates other (noninvasive methods for detection of vascular lesions: color Doppler ultrasonography of the temporal arteries, fluorescein angiography of the retina, mag-netic resonance angiography, magnetic resonance imaging, and computed tomography to rule out aortic aneurysm. Dynamic 18F positron emission tomography is demonstrated to play a role in the evaluation of therapeutic effectiveness.

    The CT diagnosis of intestinal diseases was evaluated in 140 patients. The results were as follows. 1) In the basic study on the contrast material for CT of intestinal tract examined by using experimental tumor model and cow's colon, olive oil showed highest evaluation as a contrast material. 2) Clinically, It was suggested that olive oil was most useful as a contrast material for CT of rectum and sigmoid colon and tepid water was available for small intestine, large intestine except for sigmoid colon and rectum. 3) CT examination of colon was done on 94 patients with colon malignant tumor. CT findings were compared with pathological findings, and diagnostic criteria of CT for the detection of the degree colon wall invasion was made. 4) Diagnostic accuracy of CT for swollen lymphonodes showed high rate in the para-rectal and para-aortic lymphonodes region. On the other hand, diagnostic accuracy for mesenteric dissemination of malignant tumor was low except for massive ascites. 5) CT was also useful for detection of the extraluminal lesion in inflammatory intestinal disease.

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

    The aim of this study was to present our experience in MRI diagnosis of 23 patients with the clinical findings suggesting Tolosa-Hunt syndrome (THS). Cranial MRI studies of the patients with a clinical history of at least one episode of unilateral or bilateral orbital and periorbital pain, and associated paresis of one or more of third to sixth cranial nerves, were performed on a 1.5-T MRI scanner. Whereas 5 patients had the diagnosis of THS, paracavernous meningiomas in 4 patients, pituitary macroadenomas with cavernous sinus infiltration in 3 patients, Meckel's cave neurinoma in 1 patient, and suprasellar epidermoid in 1 patient were surgically proven MRI findings. Other pathological MRI findings were leptomeningeal metastases in 3 patients, granulomatous pachymeningitis sequelae in 2 patients, and aneurysm with compression on cavernous sinus in 1 patient. Three patients had normal MRI findings. The incidence of radiologically proven diagnosis of THS among the patients with the clinical findings suggesting THS seemed to be low in our study. In conclusion, MRI is the most valuable imaging technique to distinguish THS from other THS-like entities, and permits a precise assessment, management, and therapeutic planning of the underlying pathological conditions.

  18. Comparison of clinical samples for visceral Leishmaniasis diagnosis in asymptomatic dogs by PCR hybridization

    International Nuclear Information System (INIS)

    The canine visceral leishmaniasis (CVL) diagnosis still represents a challenge because of complexity of this disease. The aim of present study was to compare different clinical samples for diagnosis of CVL by Polymerase Chain Reaction (PCR) combined with hybridization of 32P labeled probes. Bone marrow (BM), skin biopsy (SB), peripheral blood (PB) and conjunctival swab (CS) were used in this work. With this purpose 40 asymptomatic dogs, all positive by parasitological test, were obtained. From each animal were collected SB with sterile punches from ear internal surface, 1.0 mL of PB, BM aspirates from sternum and CS from both lower eyelid. Each clinical sample was submitted to suitable DNA purification process and PCR-hybridization assays. The positive results obtained with PCR were 55%, 25%, 30% and 22.5% for CS, BM, SB and PB respectively while the PCR followed by hybridization showed a positivity of 87.5%, 50%, 45% and 27.5% respectively. The hybridization assay was able to increase the PCR positivity in all kinds of clinical samples. The best performance was obtained using CS samples. We concluded that the PCR associated with DNA radioactive probes was a very sensitive tool for diagnosis of CVL in asymptomatic dogs and the CS has an important potential for regular screening of dogs.

    2016-04-01

    Orbital myositis (OM) is a rare disease whose clinical heterogeneity and different treatment options represent a diagnostic and therapeutic challenge. We aim to review the state of knowledge on OM, also describing a cohort of patients diagnosed in our centre, to highlight some remarkable clinical features. A literature review was conducted in PubMed and Medline databases. The herein described cohort is composed of seven OM patients, diagnosed according to clinical, laboratory and neuroradiological features, whose clinical data were retrospectively analysed. OM is a non-infectious, inflammatory process primarily involving extraocular eye-muscles. It typically presents as an acute to sub-acute, painful ophthalmoplegia with signs of ocular inflammation, but atypical cases without pain or with a chronic progression have been described. The wide range of OM mimicking diseases make a prompt diagnosis challenging but orbit MRI provides valuable clues for differential diagnosis. Timely treatment is greatly important as OM promptly responds to steroids; nevertheless, partial recovery or relapses often occur. In refractory, recurrent or steroid-intolerant cases other therapeutic options (radiotherapy, immunosuppressants, immunoglobulins) can be adopted, but the most effective therapeutic management is yet to be established. In this review, we provide a detailed clinical description of OM, considering the main differential diagnoses and suggesting the most useful investigations. In light of the currently available data on therapy efficacy, we propose a therapeutic algorithm that may guide neurologists in OM patients' management. PMID:26477021

    Full Text Available Physicians often encounter diagnostic problems with ambiguous and conflicting features. What are they likely to do in such situations? We presented a diagnostic scenario to 84 family physicians and traced their information gathering, diagnoses and management. The scenario contained an ambiguous feature, while the other features supported either a cardiac or a musculoskeletal diagnosis. Due to the risk of death, the cardiac diagnosis should be considered and managed appropriately. Forty-seven participants (56\\% gave only a musculoskeletal diagnosis and 45 of them managed the patient inappropriately (sent him home with painkillers. They elicited less information and spent less time on the scenario than those who diagnosed a cardiac cause. No feedback was provided to participants. Stimulated recall with 52 of the physicians revealed differences in the way that the same information was interpreted as a function of the final diagnosis. The musculoskeletal group denigrated important cues, making them coherent with their representation of a pulled muscle, whilst the cardiac group saw them as evidence for a cardiac problem. Most physicians indicated that they were fairly or very certain about their diagnosis. The observed behaviours can be described as coherence-based reasoning, whereby an emerging judgment influences the evaluation of incoming information, so that confident judgments can be achieved even with ambiguous, uncertain and conflicting information. The role of coherence-based reasoning in medical diagnosis and diagnostic error needs to be systematically examined.

    Full Text Available Abstract Background Low back pain (LBP is common and costly. Development of accurate and efficacious methods of diagnosis and treatment has been identified as a research priority. A diagnosis-based clinical decision guide (DBCDG; previously referred to as a diagnosis-based clinical decision rule has been proposed which attempts to provide the clinician with a systematic, evidence-based means to apply the biopsychosocial model of care. The approach is based on three questions of diagnosis. The purpose of this study is to present the prevalence of findings using the DBCDG in consecutive patients with LBP. Methods Demographic, diagnostic and baseline outcome measure data were gathered on a cohort of LBP patients examined by one of three examiners trained in the application of the DBCDG. Results Data were gathered on 264 patients. Signs of visceral disease or potentially serious illness were found in 2.7%. Centralization signs were found in 41%, lumbar and sacroiliac segmental signs in 23% and 27%, respectively and radicular signs were found in 24%. Clinically relevant myofascial signs were diagnosed in 10%. Dynamic instability was diagnosed in 63%, fear beliefs in 40%, central pain hypersensitivity in 5%, passive coping in 3% and depression in 3%. Conclusion The DBCDG can be applied in a busy private practice environment. Further studies are needed to investigate clinically relevant means to identify central pain hypersensitivity, poor coping and depression, correlations and patterns among the diagnostic components of the DBCDG as well as inter-examiner reliability and efficacy of treatment based on the DBCDG.

    2015-01-01

    Full Text Available Nocardiosis is an opportunistic infection caused by the Gram-positive weakly acid-fast, filamentous aerobic Actinomycetes. The lungs are the primary site of infection mainly affecting immunocompromised patients. In rare circumstances even immunocompetent hosts may also develop infection. Diagnosis of pulmonary nocardiosis is usually delayed due to nonspecific clinical and radiological presentations which mimic fungal, tuberculous, or neoplastic processes. The present report describes a rare bronchoscopic presentation of an endobronchial nocardial mass in a 55-year-old immunocompetent woman without underlying lung disease. The patient exhibited signs and symptoms of unresolving community-acquired pneumonia with a computed tomography (CT scan that showed a space-occupying lesion and enlarged paratracheal lymph node. This patient represents the unusual presentation of pulmonary Nocardia beijingensis as an endobronchial mass. Pathology obtained during bronchoscopy demonstrated polymerase chain reaction (PCR confirmation of nocardiosis. Symptoms and clinical findings improved with antibiotic treatment. This patient emphasizes the challenge in making the diagnosis of pulmonary nocardiosis, especially in a low risk host. A literature review presents the difficulties and pitfalls in the clinical assessment of such an individual.

  9. Secondary acute pancreatitis to hypertriglyceridemia: presentation of two clinical cases

    International Nuclear Information System (INIS)

    The acute pancreatitis is a reversible inflammatory process. Hypertriglyceridemia as etiology of the acute pancreatitis reaches frequencies between 1,3 to 11% according to literature when the triglycerides levels of reach values over 1000 mg/dl nevertheless hypertriglyceridemia is observed in 12 to 39% of the acute pancreatitis like factor associate. The objective of the medical treatment is to increase the activity of lipoproteinlipasa and to increase the degradation of vhylomicrones; diminishing therefore the serum triglycerides values of a levels smaller to 500 even to less of 200 mg/dl if is possible with different strategies among of them the insulin. In the present article, we presented two clinical cases of severe pancreatitis induced by hypertriglyceridemia, handled with therapy of insulin infusion with suitable evolution and clinical answer given by significant diminution of the levels of triglycerides, 48 hours post treatment

    2016-01-01

    BACKGROUND Anaphylactoid syndrome of pregnancy (ASP) is a rare but extremely serious complication, with an estimated incidence in North America of 1 in 15 200 deliveries. Despite its rarity, ASP is responsible for approximately 10% of all childbirth-associated deaths in the United States. At present, there is no validated biomarker or specific set of risk factors sufficiently predictive of ASP risk to incorporate into clinical practice. Toward the goal of developing a methodology predictive of an impending ASP event for use by obstetricians, anesthesiologists, and other practitioners participating in infant deliveries, physicians encountering an ASP event have been encouraged to report the occurrence of a case and its biologically plausible risk factors.  CASE REPORT Herein, we report on 2 patients who presented with a presumptive diagnosis of ASP to the delivery unit of a community hospital. Patient One was a 21-year-old, obese (5'11" tall, 250 lbs., BMI 34.9) white female, 1 pregnancy, no live births (G1P0), estimated gestational age (EGA) 40.2 weeks. Patient Two was a 29-year-old, obese (5'7" tall, 307 lbs., BMI 48.1) Hispanic female, second pregnancy, with 1 previous live birth via C-section (G2P1-0-0-1). Her pregnancy was at gestational age 38 weeks plus 2 days. CONCLUSIONS Patient One had 2 possible risk factors: administration of Pitocin to induce labor and post-coital spotting from recent intercourse. Patient Two suffered premature rupture of the placental membranes. Both Patient One and Patient Two had very high body mass indices (BMIs), at the 97th and 99th percentiles, respectively. In the relatively few cases of anaphylactoid syndrome of pregnancy described to date, this is the first report of a possible association with high BMI. PMID:27363628

    Lumbar vertebral fractures vary greatly in types and causes and usually result from severe trauma or pathological conditions such as osteoporosis. Lumbar wedge compression fractures are amongst the most common ones where the vertebra is severely compressed forming a wedge shape and causing pain and pressure on the nerve roots and the spine. Since vertebral segmentation is the first step in any automated diagnosis task, we present a fully automated method for robustly localizing and segmenting the vertebrae for preparation of vertebral fracture diagnosis. Our segmentation method consists of five main steps towards the CAD(Computer-Aided Diagnosis) system: 1) Localization of the intervertebral discs. 2) Localization of the vertebral skeleton. 3) Segmentation of the individual vertebra. 4) Detection of the vertebrae center line and 5) Detection of the vertebrae major boundary points. Our segmentation results are promising with an average error of 1.5mm (modified Hausdorff distance metric) on 50 clinical CT cases i.e. a total of 250 lumbar vertebrae. We also present promising preliminary results for automatic wedge compression fracture diagnosis on 15 cases, 7 of which have one or more vertebral compression fracture, and obtain an accuracy of 97.33%.

    The CT imaging and clinical presentation in 14 children with coexistent intracranial sepsis and sinusitis were reviewed. A routine CT head scan (10-mm thick semi-axial slices through the cranium done before and after intravenous contrast medium administration) was found to be an inadequate initial investigation as the intracranial collection was missed in four patients and the abnormal sinuses not shown in six. In half the children the dagnosis of sinusitis was unsuspected at the time of admission. The dominant clinical features were fever, intense headache and facial swelling in early adolescent males. In this clinical setting we recommend: (1) The routine scan is extended through the frontal and ethmoidal sinuses and photographed at a window level and width showing both bone detail and air/soft tissue interfaces; (2) direct coronal projections are performed through the anterior cranial fossa if no collection is seen on the routine study; (3) an early repeat scan within 48 h if the initial study shows no intracranial pathology but the fronto-ethomoidal sinuses are abnormal and there is a high clinical supicion of intracranial sepsis; and (4) in the presence of intracranial sepsis the vault is viewed at bone window settings to exclude cranial osteomyelitis.

    Full Text Available Abstract Background Hereditary hemochromatosis (HH is a common inherited disorder of iron metabolism in Northern European populations. The discovery of a candidate gene in 1996 (HFE, and of its main mutation (C282Y, has radically altered the way to diagnose this disease. The aim of this study was to assess the impact of the HFE gene discovery on the clinical presentation and epidemiology of HH. Methods We studied our cohort of 415 patients homozygous for the C282Y allele and included in a phlebotomy program in a blood centre in western Brittany, France. Results In this cohort, 56.9% of the patients were male and 21.9% began their phlebotomy program before the implementation of the genetic test. A significant decrease in the sex ratio was noticed following implementation of this DNA test, from 3.79 to 1.03 (p -5, meaning that the proportion of diagnosed females relatives to males greatly increased. The profile of HH patients at diagnosis changed after the DNA test became available. Serum ferritin and iron values were lower and there was a reduced frequency of clinical signs displayed at diagnosis, particularly skin pigmentation (20.1 vs. 40.4%, OR = 0.37, p Conclusion This study highlights the importance of the HFE gene discovery, which has simplified the diagnosis of HH and modified its clinical presentation and epidemiology. This study precisely measures these changes. Enhanced diagnosis of HFE-related HH at an early stage and implementation of phlebotomy treatment are anticipated to maintain normal life expectancy for these patients.

    2013-01-01

    Full Text Available Ethylene glycol (EG may be consumed accidentally or intentionally, usually in the form of antifreeze products or as an ethanol substitute. EG is metabolized to toxic metabolites. These metabolites cause metabolic acidosis with increased anion gap, renal failure, oxaluria, damage to the central nervous system and cranial nerves, and cardiovascular instability. Early initiation of treatment can reduce the mortality and morbidity but different clinical presentations can cause delayed diagnosis and poor prognosis. Herein, we report a case with the atypical presentation of facial paralysis, hematuria, and kidney failure due to EG poisoning which progressed to end stage renal failure and permanent right peripheral facial nerve palsy.

    Full Text Available Gary Ventolini, Ravi Patel, Robert Vasquez Texas Tech University Health Sciences Center Permian Basin, Odessa, TX, USA Objective: Lichen sclerosus (LS is a chronic progressive inflammatory autoimmune-induced disease that primarily affects the epidermis and dermis of the external genital-anal region. Intense and recalcitrant pruritus is the hallmark of LS. Physical exam reveals thinning, hyperkeratosis, and parchment-like appearance. However, the classic symptom and signs of LS may not always be present and patients may be asymptomatic for pruritus. Hence, we describe 15 misdiagnosed cases with atypical clinical presentations. We believe that the absence of pruritus contributed to their initial misdiagnosis. The purpose of this paper is to increase awareness of atypical presentations of LS. Methods: Data base review of de-identified clinical case pictures was performed. All patients had histopathology-confirmed diagnoses of LS. The data base file contains 800 cases of vulvovaginal disorders. The Institutional Review Board (IRB considered that searching a de-identified data base of pictures did not require IRB approval. Results: We identified 15 different atypical clinical cases. Patient ages were 18–75 years old. These patients were asymptomatic for pruritus and were misdiagnosed before they presented to the vulvovaginal specialized clinic. Conclusion: Fifteen patients asymptomatic for pruritus with histopathology-confirmed diagnosis of LS were identified. They illustrate atypical clinical presentations that LS may have.

    This article reviews the present state of knowledge concerning obsessive-compulsive disorder (OCD) with respect to its classification, epidemiology, pathogenesis, and therapy. Epidemiological evidence has indicated that OCD may be one of the most prevalent and disabling psychiatric disorders. There is also a high comorbidity with depression and anxiety disorders. OCD is characterized by repetitive, intrusive thoughts and images, and/or by repetitive, ritualistic physical or mental acts performed to reduce the attended anxiety. OCD is relatively common, affecting 1-3% of both adult and paediatric samples. OCD is clinically a heterogeneous condition in that two different patients with clear OCD can display completely distinct symptom patterns. Furthermore, neurobiological and psychological models concerning OCD as well as the present state of therapy are presented in detail. PMID:21432837

    Full Text Available Introduction: HCL is a rare malignant condition that is curable if diagnosed early. HCL can present with reduced blood cells and splenomegaly which maybe misdiagnosed with other conditions. The aim of the present study was to determine the frequency of early clinical and laboratory findings as well as the response rate of patients to the standard treatment regimen of Cladribine. Methods: The study was an uncontrolled clinical trial including 25 HCL patients referring to Oncology Clinics of Shahid Sadoughi (Yazd - Iran and Shahid Beheshti (Tehran - Iran between 1999 and 2005. Data was gathered by a pre–designed questionnaire. 21 out of 25 patients were treated with Cladribine and the clinical and laboratory response was assessed. Results: Of the 25 patients studied, 20 patients (80% were male and 5 patients (20% were female. Most of the patients at diagnosis were 55–67 years old and the most common presenting symptom was fatigue and lassitude secondary to anemia. Two patients were asymptomatic and were diagnosed incidentally. Splenomegaly was the main clinical finding which was present in about 80% of the males and all of the females. Accordingly, hairy cells in the peripheral blood smear, leukopenia and anemia were the most common laboratory findings. In contrast to previous results, pancytopenia was found in only 60% of the patients. Response rate was 90% (19 out of 21 of which 61.9% (13 patients and 28.5% (6 patients had complete remission (CR and partial remission (PR, respectively. Conclusion: According to the results, it can be concluded that HCL should be considered as a possible diagnosis in the context of fatigue, splenomegaly and reduced blood cell count. The results of the present study were similar to other similar international studies.

    Full Text Available We report a case of a 61-year-old woman who presented with acute psychosis as a major manifestation of Legionnaires’ disease in the absence of other neuropsychiatric symptoms. Clinical history revealed dry cough and nausea. Observation showed fever and auscultation crackles in the lower lobe of the right lung. Laboratory testing demonstrated elevated C-reactive protein and lung chest radiograph showed patchy peribronchial and right lower lobe consolidation. Soon after admission, she started producing purulent sputum. Epidemiological data suggested Legionella pneumophila as possible cause of the clinical picture that was confirmed by urinary antigen detection and polymerase chain reaction of the sputum. She was treated with levofloxacin 750 mg/day for 10 days with complete remission of pulmonary and psychiatric symptoms. She has not had further psychotic symptoms.

The second group is not HPV associated and occurs often in elderly women without neoplastic epithelial disorders. Histology: Squamous cell carcinoma (SCC is the most common malignant tumor of the vulva (95%. Clinical features: Pruritus is the most common and long-lasting reported symptom of vulvar cancer, followed by vulvar bleeding, discharge, dysuria, and pain. Therapy: The gold standard for even a small invasive carcinoma of the vulva was historically radical vulvectomy with removal of the tumor with a wide margin followed by an en bloc resection of the inguinal and often the pelvic lymph nodes. Currently, a more individualized and less radical treatment is suggested: a radical wide local excision is possible in the case of localized lesions (T1. A sentinel lymph node (SLN biopsy may be performed to reduce wound complications and lymphedema. Prognosis: The survival of patients with vulvar cancer is good when convenient therapy is arranged quickly after initial diagnosis. Inguinal and/or femoral node involvement is the most significant prognostic factor for survival.

    Full Text Available The rising prevalence of diabetes mellitus (DM worldwide, especially in developing countries, and the persistence of tuberculosis (TB as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil.We performed a retrospective analysis of a TB patient cohort (treatment naïve of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups.DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups.These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB reference centers in endemic

    AIM: To assess the clinical presentation and genotypes of delta hepatitis in local population.METHODS: In this prospective study, 39 consecutive patients who were positive for HBsAg and hepatitis D virus (HDV) antibody were included. The patients were divided in two groups on the basis of presence or absence of HDV RNA and a comparative study was done. Genotype of HDV was determined in PCR positive patients.RESULTS: Overall there is male dominance, in which 34 patients out of 39 (87.2%) were male. Twenty (51%) patients were from the adjacent areas of three provinces; Sindh, Punjab and Balochistan indicating the higher prevalence of delta hepatitis in this mid region of Pakistan. Patients of all age groups were affected with delta hepatitis (median 31.5 years, range 12-75).HDV RNA was detectable in 23 patients (59%). All the HDV strains belonged to genotype Ⅰ. HBV DNA was detectable only in 3 cases who were also HBeAg and HDV RNA positive. Patients with detectable HDV RNA were younger than patients with undetectable RNA; mean age 29.7 ± 12.8 years vs 36.8 ± 15.2.There were no statistically significant differences in the clinical presentation and routine biochemical profile of patients with detectable or undetectable HDV RNA.Clinical cirrhosis was present in 19 (49%) patients; 12 with detectable RNA and 7 with undetectable HDV RNA (P = 0.748). Decompensated disease was seen in eight patients; five and three respectively from each group.Four patients with undetectable RNA and two patients with detectable RNA had normal ALT and ultrasound abdomen.CONCLUSION: HDV may infect at any age, usually young adult males. Genotype Ⅰ is prevalent. With time some of the patients become HDV RNA negative or asymptomatic carrier. Most of the patients have suppressed HBV DNA replication. Significant numbers of patients have cirrhosis.

    Full Text Available Jean-Jacques WyndaeleDepartment of Urology, Antwerp University, Antwerp, BelgiumAbstract: Overactive bladder is a symptom syndrome with urgency, frequency and, in many cases, nocturia. Urge incontinence is not present in all. There is no direct correlation with detrusor overactivity, an objective finding during urodynamic testing where involuntary contractions can be noticed. In the pathophysiology, much more attention has been given to the afferent/sensory arm of the micturition reflex in the last decade. Anatomical and infectious causes have to be diagnosed or ruled out. Diagnosis of overactive bladder is made mostly by history-taking, but other tests can be necessary in specific patients. Treatment consists of behavioral measures, a good explanation of the condition, training, and pelvic floor physiotherapy. Drugs are often used. Until recently, antimuscarinic drugs have been the mainstay of pharmacological therapy. Fesoterodine is a newer antimuscarinic agent which is more pharmacodynamically stable then tolterodine. Fesoterodine has been extensively researched using different dosages and compared with placebo and tolterodine, in different age groups, and under different conditions. Fesoterodine is superior to placebo and to tolterodine in the short term and long term. Its safety is very acceptable.Keywords: overactive bladder, fesoterodine, incontinence, urgency, lower urinary tract

    Full Text Available BACKGROUND: We tested the relevance of clinical information in the histopathologic evaluation of melanocytic skin neoplasm (MSN. METHODS: Histopathologic specimens from 99 clinically atypical MSN were circulated among ten histopathologists; each case had clinical information available in a database with a five-step procedure (no information; age/sex/location; clinical diagnosis; clinical image; dermoscopic image; each step had a histopathologic diagnosis (D1 through D5; each diagnostic step had a level of diagnostic confidence (LDC ranging from 1 (no diagnostic certainty to 5 (absolute diagnostic certainty. The comparison of the LDC was employed with an analysis of variance (ANOVA for repeated measures. FINDINGS: In D1 (no information, 36/99 cases (36.3% had unanimous diagnosis; in D5 (full information available, 51/99 cases (51.5% had unanimous diagnosis (p for difference between proportions <0.001. The observer agreement expressed as kappa increased significantly from D1 to D5. The mean LDC linearly increased for each observer from D1 through D5 (p for linear trend <0.001. On average, each histopathologist changed his initial diagnosis in 7 cases (range: 2-23. Most diagnostic changes were in D2 (age/sex/location. INTERPRETATION: The histopathologic criteria for the diagnosis of MSN can work as such, but the final histopathologic diagnosis is a clinically-aided interpretation. Clinical data sometimes reverse the initial histopathologic evaluation.

    Full Text Available Abstract Introduction Penile fracture is an uncommon urologic emergency, and is the traumatic rupture of the tunica albuginea covering the corpus cavernosa. This usually occurs following blunt trauma sustained during coitus, masturbation or self-manipulations to hide or suppress an erection. Clinical diagnosis can often be easily made with typical history and examination findings. However, the patient may present atypically and/or with a suspicion of associated urethral injury. The roles of various diagnostic investigations are being evaluated in these situations. Case presentation We report the case of a 31-year-old African man with penile fracture and suspected associated urethral injury that occurred after self-manipulations to hide an erection. Conclusions Penile ultrasound and sonourethrography provide useful additional diagnostic information to supplement clinical history and physical examination findings and can be performed easily, at low cost and with no delays to surgery.

    2007-09-01

    We retrospectively analyzed 77 patients with pathologically diagnosed angioimmunoblastic T-cell lymphoma from a single city. There were 43 men and 34 women; the median age was 64.5 years (range, 30-91 yr). Average time between first symptoms of the disease and diagnosis was 3.6 months. At diagnosis, peripheral nodes were present in all but 1 patient, and were generalized in 90% of cases. Constitutional symptoms were reported in 77% of cases and spleen enlargement in 51%. A cutaneous eruption--morbilliform, urticarial, or more polymorphic--was present in 45% of patients; in one-third of them, the eruption occurred after drug administration. Other clinical manifestations included pleuritis (22%); arthralgia or arthritis (17%); ear, nose, and throat involvement (14%); central or peripheral neurologic manifestations (10%); and ascites (5%). Most patients presented with advanced disease at diagnosis (bone marrow involvement in 60% of cases). The main laboratory abnormalities were elevated lactate dehydrogenase levels (71%), inflammatory syndrome (67%), hypergammaglobulinemia (50%), anemia (51%), and lymphopenia (52%). Auto- or disimmune manifestations were reported in one-third of patients: autoimmune hemolytic anemia was present at diagnosis in 19% of patients and thrombocytopenic purpura in 7%. Documented vasculitis was described in 12% of cases. Clonality was analyzed in lymph nodes in 47 patients: T-cell and B-cell clones were found in 45 (96%) and 20 (45%) patients, respectively. Chromosomal abnormalities were identified in 62% of cases: trisomies 3, 5, 18, 19, additional X chromosome, and deletion of chromosome 7 were the most common abnormalities. The current study underlines the diversity of presenting manifestations of angioimmunoblastic T-cell lymphoma. PMID:17873758

    International Nuclear Information System (INIS)

    To determine the clinical pattern of presentation and biochemical characteristics of glycogen storage disease (GSD) type 1a in children at a tertiary referral centre. Study Design: Descriptive/ cross sectional study. Place and Duration of Study: Department of Pediatric, division of Gastroenterology and Hepatology of the Children's hospital, Lahore over a period of 11 years. Patients and Methods: Confirmed cases of glycogen storage disease (clinical plus biochemical findings consistent with GSD 1a and proven on liver biopsy) were enrolled in this study from neonatal age till 18 years. Data was retrieved from files and electronic record for these cases. Diagnosis was made on the basis of history, clinical findings including hepatomegaly, hypertriglyceridemia, hypercholesterolemia, hypoglycemia and hyperuricemia (if present). Diagnosis was confirmed on liver biopsy. Patients with other storage disorders and benign and malignant tumours were excluded from the study. Results: Total patients included in the study were 360 with male to female ratio of 1.25:1. Median age at the time of diagnosis was 25.6 months (age range from one month to 18 years). Most common presentation was abdominal distension (83%) followed by failure to thrive (69%) and recurrent wheezing and diarrhoea (44%) each. Seizures were present in only 1/3rd of children. Other presentations included vomiting, respiratory distress, altered sensorium, nephrocalcinosis, epistaxis and hypothyroidism. Few patients around 11% presented with acute hepatitis and later were diagnosed as GSD. Significant hepatomegaly was evident in almost all patients but nephromegaly was present in only 5.5% patients. All children had marked hypertriglyceridemia but cholesterol levels were raised in 1/3rd of children. A large majority of children had deranged ALT more than 2 times of normal and around 38% children had marked anemia. Significant hypoglycemia and metabolic acidosis was documented in around 1/3rd of children

    Depression is a chronic disease with a high prevalence that normally is episodic and an average episodic duration of 16 weeks. No analyses that evaluate the correlation between the evolution of the episode and its appearance have been found. The aim of this study is to analyze the correlation between symptomatic progression (appearance, maintenance, remission of different symptoms) and the evolution of the diagnosis of depression (onset, maintenance, and remission) in a cohort of patients diagnosed with and without major depression. A prospective cohort study was performed with a one year follow-up in which a random sample of 741 subjects attending primary care was interviewed. Diagnosis of depression was made according to DSM-IV criteria and symptoms presented were analyzed. These subjects were reevaluated at 6 months and 12 months. Depressed mood state, decreased interest or anhedonia and symptoms related to sleep (insomnia or hypersomnia), agitation, feeling of guilt, fatigue or energy loss, are consistent with the diagnosis. The rest of the symptoms display an evolution independent of the diagnostic trends. In Primary Care, it is important to know which are the key symptoms in the evolution of the diagnosis in order to achieve full remission of depression and avoid maintenance of residual symptoms that can become prodromal.

    Full Text Available Context: Henoch-Schφnlein purpura (HSP, a systemic IgA vascultitis, is uncommon in adults, with an incidence rate of 0.1 to 1.2 per million in adults over 20 years old. This vasculitic syndrome can present as an uncommon cause of intestinal obstruction in older patients. We report a case of an older woman with HSP presenting with small bowel obstruction and vasculitic rash. Case Report: We report a 67-year-old woman who presented with small bowel obstruction and skin rash. Skin biopsy revealed leukocytoclastic vasculitis with +IgA granular deposition within the walls of superficial dermal vessels. Kidney biopsy confirmed the diagnosis of HSP with mild mesangial proliferative IgA nephropathy. Her abdominal pain and small bowel obstruction were improved with conservative treatment. She continued to do well with normal kidney function at a 3-month follow-up visit. Conclusion: HSP, a systemic IgA vasculitis, is a predominantly pediatric vasculitis and is uncommon in adults. In adults, the disease process is identical to that in children. However, gastrointestinal manifestation is less common in older patients, and bowel perforation and obstruction are rare. Intestinal obstruction with skin rash and renal involvement should raise suspicions of HSP.

  5. A novel method of thermal tomography tumor diagnosis and its clinical practice

    International Nuclear Information System (INIS)

    When there exist diseases or functional changes in a certain part of the human body, the speed of blood flow and cell metabolism will change correspondingly, which will lead to the thermal variation in this area. To find out the relation between disease and heat distribution, a suitable bio-heat transfer model is established in this paper. Based on the infrared thermal image of human body surface, the q–r characteristic curve of heat intensity varying with depth is acquired combining the fitting method of Lorentz curve. According to a large number of clinical cases and statistics, the diagnostic criteria judging diseases by q–r characteristic curve are proposed. Several clinical practices are performed and the diagnosis results are very consistent with those of molybdenum target (MT) X-ray and B-ultrasonic images. It is a radiation-free green method with rapid diagnostic procedure and accurate diagnosis result. - Highlights: • We present a new heat-transfer mathematical model suitable for thermal tomography. • The method of acquiring the q–r characteristic curve is provided. • We propose the diagnostic criteria of female breast diseases by q–r characteristic curve. • Four typical clinical practices and the corresponding comparisons are performed

    This paper reviews current knowledge of childhood sarcoidosis with regard to the epidemiology in Danes, clinical presentation, diagnostic procedures, treatment and prognosis. Sarcoidosis is a granulomatous disease of unknown aetiology, with multiorgan involvement. The diagnosis is confirmed by the demonstration of epitheloid cell granulomas in tissue biopsy specimens. During the period 1980-92, three cases of childhood sarcoidosis were recorded in Copenhagen County, which has a total population of 610,000. The approximate incidence of clinically recognized sarcoidosis in Danish children younger than 15 y of age was 0.22-0.27/100,000 children per year, corresponding to approximately three new cases in Denmark each year. The true incidence is unknown, since the disease is often asymptomatic and resolves without a clinical diagnosis being made. In children younger than 5 y of age, the disease is characterized by involvement of skin, eyes and joints, whereas in older children involvement of lungs, lymph nodes and eyes predominate. The mainstay of treatment consists of oral corticosteroids. The risk/benefit ratio of using long-term corticosteroids needs to be evaluated in each individual patient. Some patients may benefit from additional therapy with methotrexate. The long-term prognosis is not well established, but it seems to be poorer in children younger than 5 y. Older children appear to have as favourable a prognosis as young adults. PMID:9736236

    Spinal dural arteriovenous fistula (SDAVF) is a relatively common acquired vascular malformation of the spinal cord. Assessment of a SDAVF is often difficult because of non-specific findings on non-invasive imaging modalities. Diagnosis of a SDAVF is often delayed, and some patients receive unnecessary treatment and treatment delays, often resulting in a poor outcome. The aim of this study was to characterize the clinical presentation, typical imaging findings, and long-term outcome of SDAVF. Forty patients (13 women, 27 men; mean age 58.18±standard deviation 14.75years) who were treated at our hospital from June 1992 to March 2014 were retrospectively reviewed. We investigated the baseline characteristics, clinical presentation, imaging findings, treatment modalities, and outcome of the patients. The most common clinical presentation was a sensory symptom (80%), followed by motor weakness (70%), and sphincter dysfunction (62.5%). Roughly one-third (32.5%) of patients had a stepwise progression of fluctuating weakness and sensory symptoms, but the most common presentation was chronic progressive myelopathic symptoms (47.5%). Thirty-four patients (85%) had T2 signal change on the spinal cord MRI, indicative of cord edema. Thirty-eight patients had typical perimedullary vessel flow voids on T2-weighted MRI. Twenty-eight patients were treated with endovascular embolization, five patients underwent surgery, and four patients underwent both. Clinical outcome was determined by severity of initial deficit (p=0.008), extent of cord edema (p=0.010), treatment failure (p=0.004), and a residual fistula (p=0.017). SDAVF causes a treatable myelopathy, so early diagnosis and intervention is essential. PMID:26765752

    International Nuclear Information System (INIS)

    Opinions regarding the best possible treatment of cancer of the breast are more controversial than ever. This article analyses the present state of the art in diagnosis of the carcinoma of the breast on the basis of an extensive review of published literature. The methods are evaluated with regard to their value in early recognition and mass screening. The pros and cons brought forward in the discussion on the optimum treatment of this kind of tumour are described. Since no final judgment can be passed at the present moment, an attempt is made to explain the present state of therapy according to stages as seen from the radiologist's point of view. (orig.)

    International Nuclear Information System (INIS)

    Objectives: to determine the pattern of clinical manifestations in patients with hypothyroidism and to document the clinical state, the laboratory findings and the effect of therapy on those who restrict themselves to the long term medication and follow up. Design: a prospective study on all patients in whom a clinical suspicious of being hypothyroidism,this was during a period from the first of june 1997 to the end of december 1998 (18 months). Subjects: the study population comprised two groups of patients: a) patients presenting for the first time (n:20). b) patients previously known to be hypothyroidism but stopped the medication for a while from 6 months up to one year or more (n:16). Methods: data was collected through a questionnaire detailing the medical history, medical examination and the laboratory investigations which were performed. Results: hypothyroidism is a disease of female although it's rare but can be encountered, the diagnosis is delayed because of the wide range of symptoms, the commonest were fatigue (88.9%), myalgia (75%), hoarseness of voice (72.2%), dry skin (63.9%), these patients may present with constipation (44.4%) or to the gyne because of menorrhagia (47.2%),or to the psychiatry because of change in mood (41.7%) signs such as delayed relaxation of the knee jerk (83.3%),proximal myopathy (38.9%), perorbital swelling (50%) or loss of eye brows (27.8%) can help in the diagnosis. Conclusion: hypothyroidism is rare in the Sudan, for the diagnosis not to be delayed one should be familiar with the different manifestations in order to be able to elicit appropriate signs. The treatment is satisfactory, responsive to thyroxine which should be life long therapy

    Dyskinesia of the scapula is a clinical diagnosis and includes all disorders affecting scapula positioning and movement whatever its etiology. Scapular winging is a subtype of scapular dyskinesia due to a dynamic prominence of the medial border of the scapula (DSW) secondary to neuromuscular imbalance in the scapulothoracic stabilizer muscles. The two most common causes of DSW are microtraumatic or idiopathic lesions of the long thoracic nerve (that innerves the serratus anterior) or the accessory nerve (that innerves the trapezius). Diagnosis of DSW is clinical and electromyographic. Use of magnetic resonance imaging (MRI) could be of interest to distinguish lesion secondary to a long thoracic nerve from accessory nerve and to rule out scapular dyskinesia related to other shoulder disorders. Causal neuromuscular lesion diagnosis in DSW is challenging. Clinical examinations, combined with scapular MRI, could help to their specific diagnosis, determining their stage, ruling out differential diagnosis and thus give raise to more targeted treatment.

    Stress fracture, in its most inclusive description, includes both fatigue and insufficiency fracture. Fatigue fractures, sometimes equated with the term "stress fractures," are most common in runners and other athletes and typically occur in the lower extremities. These fractures are the result of abnormal, cyclical loading on normal bone leading to local cortical resorption and fracture. Insufficiency fractures are common in elderly populations, secondary to osteoporosis, and are typically located in and around the pelvis. They are a result of normal or traumatic loading on abnormal bone. Subchondral insufficiency fractures of the hip or knee may cause acute pain that may present in the emergency setting. Medial tibial stress syndrome is a type of stress injury of the tibia related to activity and is a clinical syndrome encompassing a range of injuries from stress edema to frank-displaced fracture. Atypical subtrochanteric femoral fracture associated with long-term bisphosphonate therapy is also a recently discovered entity that needs early recognition to prevent progression to a complete fracture. Imaging recommendations for evaluation of stress fractures include initial plain radiographs followed, if necessary, by magnetic resonance imaging (MRI), which is preferred over computed tomography (CT) and bone scintigraphy. Radiographs are the first-line modality and may reveal linear sclerosis and periosteal reaction prior to the development of a frank fracture. MRI is highly sensitive with findings ranging from periosteal edema to bone marrow and intracortical signal abnormality. Additionally, a brief description of relevant clinical management of stress fractures is included. PMID:27002328

The clinical presentation consists of neurological respiratory, gastrointestinal, and vasomotor disturbances. All infants require observation and supportive care to ensure appropriate adaptation and growth in the newborn period. A smaller percentage may also require additional pharmacotherapy, depending on the specific gestational substance exposure. Women should be counseled antenatally about the possible neonatal effects, and mother–baby dyad care should be implemented for this particular patient population.Keywords: neonatal withdrawal, opioids, marijuana, cocaine, benzodiazepines, selective serotonin reuptake inhibitors

    International Nuclear Information System (INIS)

    The naso labial cyst is an uncommon non-odontogenic cyst that develops in the lower region of the nasal ala; its pathogenesis is uncertain. This lesion grows slowly and measures between 1.5 and 3 cm; it is characterized clinically by a floating tumefaction in the naso labial sulcus, which elevates the upper lip. The diagnosis is based on the clinical findings and, if necessary, image exams. This paper reports a case of a white 48-year-old Brazilian female patient that presented a firm tumor in the left ala of the nose; the clinical features suggested a naso labial cyst. CT scans revealed an expanding tumor with soft tissue density located in the left ala of the nose. It measured 1.2 cm in diameter and had a clear and well-defined outline; its homogeneous density was about 50 HU. MR images revealed a circular lesion located in soft tissue; T1 and T2 weighted signals were hyperintense, as were images after fat suppression. The diagnosis was a naso labial cyst, which was confirmed by histopathology after surgery. (author)

    Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.

    Intraorbital foreign bodies usually occur after a high velocity injury such as gunshot or industrial accidents; more rarely they occur following trivial trauma. A retained foreign body can give rise to serious complications, the most devastating of which is loss of the eye. This retrospective, interventional case report reviews the clinical features, radiological appearance and surgical management of two patients who presented at Sultan Qaboos University Hospital, Oman with intraorbital foreign bodies. Details of ocular history, preoperative ocular examination findings including visual acuity, surgical procedure and subsequent management were noted. The two patients, aged 10 years and 9 years old respectively, sustained orbital trauma with sharp objects. Both patients were found to have intraorbital foreign bodies that were documented clearly by computed tomography (CT) scans of the orbit. The first patient presented straight after injury, had no ocular involvement, underwent immediate surgical exploration and ended up with full recovery. The second patient presented to us after a delay of 4 days, and was found to have endophthalmitis. This patient ultimately lost all visual function in the affected eye. A CT scan is the modality of choice for orbital foreign body detection and localization. Early surgical exploration and foreign body extraction greatly influence the visual prognosis and final outcome. PMID:21654960

    Full Text Available Abstract Background In recent years there has been increasing recognition that the pattern of presentation of coeliac disease may be changing. The classic sprue syndrome with diarrhoea and weight loss may be less common than the more subtle presentations of coeliac disease such as an isolated iron deficiency anaemia. As a result, the diagnosis of this treatable condition is often delayed or missed. Recent serologic screening tests allow non-invasive screening to identify most patients with the disease and can be applied in patients with even subtle symptoms indicative of coeliac disease. Both benign and malignant complications of coeliac disease can be avoided by early diagnosis and a strict compliance with a gluten free diet. Aim The aim of this study is to evaluate the trends in clinical presentation of patients diagnosed with adult coeliac disease. In addition, we studied the biochemical and serological features and the prevalence of associated conditions in patients with adult coeliac disease. Methods This is an observational, retrospective, cross-sectional review of the medical notes of 32 adult patients attending the specialist coeliac clinic in a district general hospital. Results Anaemia was the most common mode of presentation accounting for 66% of patients. Less than half of the patients had any of the classical symptoms of coeliac disease and 25% had none of the classical symptoms at presentation. Anti-gliadin antibodies, anti-endomysial antibody and anti-tissue transglutaminase showed 75%, 68% and 90% sensitivity respectively. In combination, serology results were 100% sensitive as screening tests for adult coeliac disease. Fifty nine percent patients had either osteoporosis or osteopenia. There were no malignant complications observed during the follow up of our patients. Conclusion Most adults with coeliac disease have a sub clinical form of the disease and iron deficiency anaemia may be its sole presenting symptom. Only a minority

  3. Prevalence, clinical presentation and treatment outcome of cryptosporidiosis in immunocompetent adult patients presenting with acute diarrhoea

    International Nuclear Information System (INIS)

    Objective: To document the prevalence, clinical presentation and treatment outcome of cryptosporidiosis in immunocompetent adult patients presenting with acute diarrhoea. Methods: This prospective cohort study was conducted at the Sindh Institute of Urology and Transplantation Karachi from February 1, till September 30, 2012. All immunocompetent adult patients who presented with acute diarrhoea to the gastroenterology clinic at SIUT were included. Data collection sheet was filled and stool studies sent. Modified acid fast stain of stool was performed for cryptosporidium. SPSS 20 was used for statistical analysis. Results: There were 105 patients with acute diarrhoea. Fifty three (50.4%) were males. The mean age was 34+-8.4 years. Of 105, 58 (55%) patients had cryptosporidium isolated in stool studies. Patients with cryptosporidiosis had statistically significant greater stool frequency per day (p<0.001,OR=12.7; CI [4.4-37.1]), abdominal pain (p<0.001, OR= 19.8 [6.1-64.1]), vomiting (p<0.001, OR=7.3 [2.7-19.9]), low grade fever (p<0.001, OR=8.5 [3.5-20.8]), fatigue (p<0.001, OR=8.4 [3.2-21.6]) and dehydration and a shorter duration of illness with more watery diarrhoea. All 58 patients reported resolution of diarrhoea after 7 days of treatment with nitazoxanide. However, 40 (70.1%) patients reported recurrence of diarrhoea within 6 weeks of treatment. Conclusion: Our study demonstrates a high prevalence of cryptosporidiosis in immunocompetent adult patients. Nitazoxanide is the recommended antimicrobial drug for cryptosporidiosis. (author)

    Primary umbilical endometriosis is a rare disorder and is defined as the presence of ectopic endometrial tissue within the umbilicus. A patient with painful mass in the umbilicus during menstrual period is studied in this paper. The possibility of subcutaneous endometriosis should be considered when an umbilical mass is detected despite the absence of previous surgery. In this case, urachal cancer, urachal remnant, umbilical endometriosis, and its malignant transformation were among the diseases considered in the differential diagnosis. Complete excision and histology are necessary to obtain a definitive diagnosis and optimal treatment for umbilical subcutaneous endometriosis.

  5. Studies on diagnosis of lung emphysema by CT image using experimental models and clinical cases

    International Nuclear Information System (INIS)

    Since the detailed report between the degree of functional disorder in lung emphysema and the analysis of CT image is quite unknown, the present study was attempted to produce the experimental model of lung emphysema with various stages by the administration of papain to the focal lobe in canine lung. Using this model or clinical lung emphysema, the relationship between the degree of destruction of alveolar walls, clinical pulmonary functions and CT images was investigated. CT scan was performed at the level of 50% vital capacity in both experimental models and clinical subjects by using spirometric gating CT. CT density histogram was obtained from CT image which was produced by using the developed software for this purpose. Densitometric parameters, such as mean CT value, %LAA, the peak in the histogram and 5% tile were selected from CT image. Papain solution of 5 mg/kg body weight was cumulatively administered to the left lower lobe in canine lung, resulting in the destruction of lung alveolar walls in parallel to the increasing dosage of papain. There was a significant correlation between not only the increasing dosage of papain, but also %FEV 1.0 and CT densitometric parameters, indicating that the histological changes of alveolar walls and the lung function in lung emphysema could be estimated by analysis of CT image. These experimental and clinical studies suggest that the analysis of CT image can reflect the pathophysiological changes in the lung and be useful for precise clinical diagnosis of lung emphysema.

  7. Clinical presentations and MRI findings of angiographically occult vascular malformations

    International Nuclear Information System (INIS)

    Various clinical features as well as MRI findings of AOVM (angiographically occult vascular malformation) were studied. Amongst out patients, since January 1988, there have been 30 cases of symptomatic AOVM (20 males, 10 females) including 4 cases with multiple lesions. The age ranged from 3 to 60 years of age, with a mean of 33.4 years. The locations of symptomatic lesions were in the cerebral hemisphere (15), the thalamus (4), the brain stem (8) and in the cerebellum (3). The initial presentations of these 30 cases were either by hemorrhage (18), convulsive seizure (9) or by progressive neurological deficits (3). The initial presentation was not related to the patient's age and the size of the lesion, but apparently related to the location of AOVM. Most of the lesions in the cerebral hemisphere presented seizures, but all of the lesions in the thalamus, the brain stem and the cerebellum disclosed hemorrhage as an initial presentation. In fact it was noticed that brain stem lesions tend to cause repetitive hemorrhage in a relatively short period. AOVM lesions were clearly visualized with T2-weighted MRI images, consisting of high intensity cores with surrounding low intensity rims. Most of the symptomatic lesions were partially enhanced by Gd-DTPA with varied intensity. Dynamic changes in size and enhancement pattern on MRI were occasionally seen, usually accompanied with episodes such as hemorrhage or neurological deterioration. Although AOVMs were angiographically negative some strands indicating draining veins were observed on MRI in several cases. In contrast, none of the nonsymptomatic lesions (22 lesions) demonstrated enhancement effects with Gd-DTPA. (author)

    Posterior cortical atrophy (PCA) is characterized by core visuospatial and visuoperceptual deficits, and predominant atrophy in the parieto-occipital cortex. The most common underlying pathology is Alzheimer's disease (AD). Existing diagnostic criteria suggest that episodic memory is relatively preserved. The aim of this study was to examine memory performance at initial clinical presentation in PCA, compared to early-onset AD patients (EOAD). 15 PCA patients and 32 EOAD patients, and 34 healthy controls were entered into the study. Patients were tested on the Addenbrooke's Cognitive Examination (ACE-R), consisting of subscales in memory and visuospatial skills. PCA and EOAD patients were significantly impaired compared to controls on the ACE total score (p skills (p skills compared to EOAD patients (p presentation. The findings suggest that memory impairment must be considered in assessment and management of PCA. Further study into memory in PCA is warranted, since the ACE-R is a brief screening tool and is likely to underestimate the presence of memory impairment. PMID:27128371

    Differential diagnosis of neck tumours puts precedence on diagnosing neoplastic lesions. In the case of neck tumours, these are unfortunately late signs, but in patients with a primary neoplastic focus within the head and neck, neck tumour is often the first sign of the disease. The authors describe a clinical case of neck tumour with initially unclear etiology. The preoperative diagnostics including ultrasonography, thin-needle puncture, MRI, carotid angiography and videostroboscopy was significant for surgical treatment planning; yet it was the intraoperative clinical picture which indicated that the tumour derived from the inferior parotid pole. The preoperative histopathological diagnosis using thin-needle biopsy: cellulae carcinomatosae and the clinical picture resulted in block operation with neck lymphatic system removal and tissue defect reconstruction by means of a pectoral flap. The histopathological examination confirmed non-cornifying basal cell epithelioma only in the essential lesion with no metastases to lymph nodes and surrounding tissue margins free of infiltrates. Two and a half years after the procedure, the patient presented with a tumour localized on the front thoracic wall and two rapidly enlarging tumours in the nape of the neck. In the collected specimen of the tumour on the front thoracic wall, a diagnosis of acinic cell carcinoma was made. The deteriorating general condition of the patient, his cancer emaciation, problems with movement and suspected liver metastases confirmed by abdominal USG as well as radiological bone lesions resulted in the abandonment of surgical treatment due to disseminated neoplastic process and the patient was referred for palliative care.

    Full Text Available Abstract Background Cow's milk is the most common food allergen in infants and the diagnosis of cow's milk allergy is difficult, even with the use of several diagnostic tests. Therefore, elimination diets and challenge tests are essential for the diagnosis and treatment of this disorder. The aim of this study is to report the clinical presentation and nutritional status of children evaluated by pediatric gastroenterologists for the assessment of symptoms suggestive of cow's milk allergy. Methods An observational cross-sectional study was performed among 9,478 patients evaluated by 30 pediatric gastroenterologists for 40 days in 5 different geographical regions in Brazil. Clinical data were collected from patients with symptoms suggestive of cow's milk allergy. The nutritional status of infants (age ≤ 24 months seen for the first time was evaluated according to z-scores for weight-for-age, weight-for-height, and height-for-age. Epi-Info (CDC-NCHS, 2000 software was used to calculate z-scores. Results The prevalence of suspected cow's milk allergy in the study population was 5.4% (513/9,478, and the incidence was 2.2% (211/9,478. Among 159 infants seen at first evaluation, 15.1% presented with a low weight-for-age z score ( Conclusion The high prevalence of nutritional deficits among infants with symptoms suggestive of cow's milk allergy indicates that effective elimination diets should be prescribed to control allergy symptoms and to prevent or treat malnutrition.

    Full Text Available Background: Paroxysmal nocturnal hemoglobinuria (PNH is characterized by intravascular hemolysis, marrow failure, nocturnal hemoglobinuria and thrombophila. This acquired disease caused by a deficiency of glycosylphosphatidylinositol (GPI anchored proteins on the hematopoietic cells is uncommon in the Indian population. Materials and Methods: Data of patients diagnosed with PNH in the past 1 year were collected. Clinical data (age, gender, various presenting symptoms, treatment information and follow-up data were collected from medical records. Results of relevant diagnostic tests were documented i.e., urine analysis, Ham′s test, sucrose lysis test and sephacryl gel card test (GCT for CD55 and CD59. Results: A total of 5 patients were diagnosed with PNH in the past 1 year. Presenting symptoms were hemolytic anemia (n=4 and bone marrow failure (n=1. A GCT detected CD59 deficiency in all erythrocytes in 4 patients and CD55 deficiency in 2 patients. A weak positive PNH test for CD59 was seen in 1 patient and a weak positive PNH test for CD55 was seen in 3 patients. All patients were negative by sucrose lysis test. Ham′s test was positive in two cases. Patients were treated with prednisolone and/or androgen and 1 patient with aplastic anemia was also given antithymocyte globulin. A total of 4 patients responded with a partial recovery of hematopoiesis and 1 patient showed no recovery. None of the patients received a bone marrow transplant. Conclusion: The study highlights the diagnostic methods and treatment protocols undertaken to evaluate the PNH clone in a developing country where advanced methods like flowcytometry immunophenotyping (FCMI and bone marrow transplants are not routinely available.

  16. CT quantitative diagnosis in fatty liver: a clinical study

    International Nuclear Information System (INIS)

    Objective: To establish the CT criteria of quantitative diagnosis for liver steatosis by means of studying the CT features of fatty liver cases proven histologically. Methods: Twenty-eight cases of fatty liver were underwent non-enhanced CT scan, and the attenuation of liver parenchyma was measured. To differentiate the degree of fatty liver, the mean CT value and the relative density of hepatic vessels were observed. The quantitative diagnosis was made according to the CT number threshold and the criteria of relative density of hepatic vessels, respectively. Results: Among the 28 cases, there were 17 cases of mild steatosis with mean CT number of 46 HU (32-65 HU), 7 cases of middle degree fatty liver with mean CT number of 28 HU (15-38 HU), and 4 cases of sever fatty liver with mean CT number of 0.2 HU (-7-11 HU). For the relative density of hepatic vessels, 16 of the 17 cases of mild fatty liver had a appearance of hepatic vessels immersion and 1 mild case had reverse hepatic vessels display, 6 of 7 middle degree cases had reverse hepatic vessels display with 1 case having the appearance of hepatic vessels immersion, and all the 4 case of sever steatosis had the appearance of reverse hepatic vessels display with sharp contrast between vessels and the liver parenchyma. The accuracy of quantitative diagnosis was 65.9% and 93.1% by means of criteria of CT number threshold and relative density of hepatic vessels, respectively (x2 = 7.153, P < 0.01). Conclusion: The criteria of relative density of hepatic vessels is more reliable than that of CT number threshold in quantitative diagnosis of fatty liver

    The use of a broad spectrum of novel detection systems for autoantibodies to the basement membrane proteins BP180 and BP230 has greatly facilitated the diagnosis of bullous pemphigoid, which most likely explains its increasing incidence in central Europe. Because the pathogenic relevance of antibodies to human BP180 has been convincingly shown both in vitro and in vivo, repeated testing for these antibodies appears to be helpful in guiding treatment decisions during the course of the disease.

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

    Full Text Available Objective. Wilson’s disease is a disorder of copper metabolism which is fatal without treatment. The great number of disease-causing ATP7B gene mutations and the variable clinical presentation of WD may cause a real diagnostic challenge. The emergence of next-generation sequencing provides a time-saving, cost-effective method for full sequencing of the whole ATP7B gene compared to the traditional Sanger sequencing. This is the first report on the clinical use of NGS to examine ATP7B gene. Materials and Methods. We used Ion Torrent Personal Genome Machine in four heterozygous patients for the identification of the other mutations and also in two patients with no known mutation. One patient with acute on chronic liver failure was a candidate for acute liver transplantation. The results were validated by Sanger sequencing. Results. In each case, the diagnosis of Wilson’s disease was confirmed by identifying the mutations in both alleles within 48 hours. One novel mutation (p.Ala1270Ile was found beyond the eight other known ones. The rapid detection of the mutations made possible the prompt diagnosis of WD in a patient with acute liver failure. Conclusions. According to our results we found next-generation sequencing a very useful, reliable, time-saving, and cost-effective method for diagnosing Wilson’s disease in selected cases.

    Full Text Available The present study compares the performance of stochastic and fuzzy models for the analysis of the relationship between clinical signs and diagnosis. Data obtained for 153 children concerning diagnosis (pneumonia, other non-pneumonia diseases, absence of disease and seven clinical signs were divided into two samples, one for analysis and other for validation. The former was used to derive relations by multi-discriminant analysis (MDA and by fuzzy max-min compositions (fuzzy, and the latter was used to assess the predictions drawn from each type of relation. MDA and fuzzy were closely similar in terms of prediction, with correct allocation of 75.7 to 78.3% of patients in the validation sample, and displaying only a single instance of disagreement: a patient with low level of toxemia was mistaken as not diseased by MDA and correctly taken as somehow ill by fuzzy. Concerning relations, each method provided different information, each revealing different aspects of the relations between clinical signs and diagnoses. Both methods agreed on pointing X-ray, dyspnea, and auscultation as better related with pneumonia, but only fuzzy was able to detect relations of heart rate, body temperature, toxemia and respiratory rate with pneumonia. Moreover, only fuzzy was able to detect a relationship between heart rate and absence of disease, which allowed the detection of six malnourished children whose diagnoses as healthy are, indeed, disputable. The conclusion is that even though fuzzy sets theory might not improve prediction, it certainly does enhance clinical knowledge since it detects relationships not visible to stochastic models.

    Full Text Available The aim of this study was to explore factors contribute to the success of PGD cycles for monogenic diseases.During a 3-year period (January 2009 to December 2012, 184 consecutive ICSI-PGD cycles for monogenic diseases reaching the ovum pick-up and fresh embryo-transfer stage performed at the Reproductive Medicine Center of The First Affiliated Hospital Of Sun Yat-sen University were evaluated.ICSI was performed on 2206 metaphase II oocytes, and normal fertilization and cleavage rates were 83.4% (1840/2206 and 96.2% (1770/1840, respectively. In the present study, 60.5% (181/299 of day 3 good-quality embryos developed into good-quality embryos on day 4 after biopsy. Collectively, 42.9% clinical pregnancy rate (79/184 and 28.5% implantation rate (111/389 were presented. In the adjusted linear regression model, the only two significant factors affecting the number of genetically unaffected embryos were the number of biopsied embryos (coefficient: 0.390, 95%CI 0.317-0.463, P = 0.000 and basal FSH level (coefficient: 0.198, 95%CI 0.031-0.365, P = 0.021. In the adjusted binary logistic regression model, the only two significant factors affecting pregnancy outcome were the number of genetically available transferable embryos after PGD (adjusted OR 1.345, 95% CI 1.148-1.575, P = 0.000 and number of oocyte retrieved (adjusted OR 0.934, 95% CI 0.877-0.994, P = 0.031.There should be at least four biopsied embryos to obtain at least one unaffected embryos in a PGD system for patients with single gene disorder and under the condition of basal FSH level smaller than 8.0mmol/L. Moreover, if only a low number (< 4 of biopsied embryos are available on day 3, the chance of unaffected embryos for transfer was small, with poor outcome.

    Full Text Available Background: Malaria has remained an important public health problem in Nigeria with children under 5 years of age bearing the greatest burden. Accurate and prompt diagnosis of malaria is an important element in the fight against the scourge. Due to the several limitations of microscopy, diagnosis of malaria has continued to be made based on clinical ground against several World Health Organization (WHO recommendations. Thus, we aim to assess the performance of empirical clinical diagnosis among febrile children under 5 years of age in a busy pediatric outpatient clinic. Materials and Methods: The study was a cross-sectional study. Children aged <5 years with fever or 72 h history of fever were recruited. Children on antimalarial prophylaxis or on treatment for malaria were excluded. Relevant information was obtained from the caregiver and clinical note of the child using interviewer administered questionnaire. Two thick and two thin films were made, stained, and read for each recruited child. Data was analysed using SPSS version 16. Results: Of the 433 children studied, 98 (22.6% were empirically diagnosed as having malaria and antimalarial drug prescribed. Twenty-three (23.5% of these children were confirmed by microscopy to have malaria parasitemia, while 75 (76.5% were negative for malaria parasitemia. Empirical clinical diagnosis show poor predictive indices with sensitivity of 19.2%, specificity of 76.0%, positive predictive value of 23.5% and negative predictive value of 71%. Conclusion and Recommendations: Empirical clinical diagnosis of malaria among the under-five children with symptoms suggestive of acute malaria is highly not reliable and hence the need to strengthen parasitological diagnosis.

    The mind-boggling progress in the understanding of the molecular mechanisms underlying the long QT syndrome (LQTS) has been the subject of many articles and reviews. Still, when it comes to the management of the patients affected by this life-threatening disorder, too many errors still take place, both in the diagnostic process and in the therapeutic choices. The price of these errors is paid by the patients and their families. This review is not directed to the relatively small number of LQTS experts who know what to do. It does not deal with genetics, with epidemiology, or with the well-known clinical manifestations. We have focused solely on the approach to diagnosis and therapy and we have directed this review to the average clinical cardiologist who, in his/her practice, sees occasionally patients affected or suspected to be affected by LQTS; the cardiologist who may know enough to manage them but not enough to be completely confident on his/her most critical choices. We have provided our personal views without making any attempt to blend differences whenever present. On most issues we agree fully but where we do not, we make it clear to the reader by indicating who is thinking what. The result may be unconventional, but it mirrors the challenges, often severe, that we all face in managing and protecting these patients from sudden death while also helping them live and thrive despite their diagnosis. We trust that this unabashed presentation of our clinical approach will be useful for both cardiologists and patients. PMID:23509228

    Full Text Available Objective: To determine time delay from the onset of initial symptoms to diagnosis of primary lung cancer. Materials and Methods: Selected information was captured from 49 consecutive pathologically proven cancer lung patients presenting to a tertiary respiratory centre during 1 st January to 30 th June 2012 using semi-structured interview schedule. All patients underwent suitable protocol based diagnostic work-up and referral. Results: Background profile of patient was as follows: Male:Female = 7.1:1; mean age was 61.2 (±9.7 years; Nine out of 49 (18.4% patients were illiterate; Forty-three out of 49 (87.8% belonged to rural native place; Forty-three out of 49 (87.7% were smokers with 25 years as median pack-years. Histological profile showed that adenocarcinoma (40.8% was the predominant form followed by small cell carcinoma (32.7%. Time (median delay in diagnosis was 3.0 days (home remedies/quack therapy, 60.0 days (primary/secondary level and 8 days at tertiary level. Twenty seven of 49 patients (55.1% presented in stage-IV. Higher proportion of patients residing outside the district of study institute had longer delay in diagnosis but did not reach statistical significance (P > 0.05. The most important patient reasons for the delay in diagnosis was procrastinate/did not took symptoms seriously (19/49, 38.7%; no-body to escort (13/49, 26.5%, long distance (5/49, 10.2%, financial constraints (4/49, 8.1%, preferred local practitioner (2/49, 4.0%, family commitment/marriage (2/49, 4.0%, fear of death (1/49, 2.0% and no reason cited (3/49, 6.1%. Three patients were inadvertently diagnosed as tuberculosis and hence the delay. Conclusion: Patient presented at a higher stage within a short span of time; however, there is scope of increasing health system capacity at primary/secondary level including sensitization training, health communication and appropriate referral to higher center.

    Systemic mastocytosis is a rare heterogeneous myeloproliferative neoplasm characterized by abnormal proliferation and activation of mast cells. We describe a large multicentre series of 460 adult patients with systemic mastocytosis, with a diagnosis based on WHO 2008 criteria, in a "real-life" setting of ten Italian centers with dedicated multidisciplinary programs. We included indolent forms with (n = 255) and without (n = 165) skin lesions, smouldering (n = 20), aggressive (n = 28), associated with other hematological diseases mastocytosis (n = 21) and mast cell leukemia (n = 1). This series was uniquely characterized by a substantial proportion of patients with low burden of neoplastic mast cells; notably, 38% of cases were diagnosed using only minor diagnostic criteria according to WHO 2008 classification, underlying the feasibility of early diagnosis where all diagnostic approaches are made available. This has particular clinical relevance for prevention of anaphylaxis manifestations, that were typically associated with indolent forms. In multivariate analysis, the most important features associated with shortened overall survival were disease subtype and age at diagnosis >60 years. Disease progression was correlated with mastocytosis subtype and thrombocytopenia. As many as 32% of patients with aggressive mastocytosis suffered from early evolution into acute leukemia. Overall, this study provides novel information about diagnostic approaches and current presentation of patients with SM and underlines the importance of networks and specialized centers to facilitate early diagnosis and prevent disease-associated manifestations.

    Mutations in BRAT1, encoding BRCA1-associated ATM activator 1, are associated with a severe phenotype known as rigidity and multifocal seizure syndrome, lethal neonatal (RMFSL; OMIM # 614498), characterized by intractable seizures, hypertonia, autonomic instability, and early death. We expand the phenotypic spectrum of BRAT1 related disorders by reporting on four individuals with various BRAT1 mutations resulting in clinical severity that is either mild or moderate compared to the severe phenotype seen in RMFSL. Representing mild severity are three individuals (Patients 1-3), who are girls (including two sisters, Patients 1-2) between 4 and 10 years old, with subtle dysmorphisms, intellectual disability, ataxia or dyspraxia, and cerebellar atrophy on brain MRI; additionally, Patient 3 has well-controlled epilepsy and microcephaly. Representing moderate severity is a 15-month-old boy (Patient 4) with severe global developmental delay, refractory epilepsy, microcephaly, spasticity, hyperkinetic movements, dysautonomia, and chronic lung disease. In contrast to RMFSL, his seizure onset occurred later at 4 months of age, and he is still alive. All four of the individuals have compound heterozygous BRAT1 mutations discovered via whole exome sequencing: c.638dupA (p.Val214Glyfs*189); c.803+1G>C (splice site mutation) in Patients 1-2; c.638dupA (p.Val214Glyfs*189); c.419T>C (p.Leu140Pro) in Patient 3; and c.171delG (p.Glu57Aspfs*7); c.419T>C (p.Leu140Pro) in Patient 4. Only the c.638dupA (p.Val214Glyfs*189) mutation has been previously reported in association with RMFSL. These patients illustrate that, compared with RMFSL, BRAT1 mutations can result in both moderately severe presentations evident by later-onset epilepsy and survival past infancy, as well as milder presentations that include intellectual disability, ataxia/dyspraxia, and cerebellar atrophy. © 2016 Wiley Periodicals, Inc.

    Full Text Available The interrelationship between periodontal and endodontic disease has aroused confusion, queries and controversy. Differentiating between periodontal and endodontic problems can be difficult. A symptomatic tooth may have pain of periodontal and/or pulpal origin. The nature of that pain is often the first clue in determining the etiology of such a problem. Radiographic and clinical evaluation can help clarify the nature of the problem. In some cases, the influence of pulpal pathology may create periodontal involvement. In others, periodontal pathology may create pulpal pathology. This review article discusses the various clinical aspects to be considered for accurately diagnosing and treating endo-perio lesions.

    Improving the efficiency of malaria diagnosis is one of the main goals of current malaria research. We have recently developed a magneto-optical (MO) method which allows high-sensitivity detection of malaria pigment (hemozoin) crystals via their magnetically induced rotation in blood. Here, we validate this technique on laboratory derived blood samples infected with \\textit{Plasmodium falciparum}. Using two parasite cultures, the first containing mostly ring stages and the second corresponding to the end of the parasite life cycle, we demonstrate that our novel method can detect parasite densities as low as $\\sim$40 and $\\sim$10\\,parasites per microliter of blood for ring and schizont stage parasites, respectively. This detection limit exceeds the performance of rapid diagnostic tests and competes with the threshold achievable by light microscopic observation of blood smears. Our method can be performed with as little as 50\\,microliter of capillary blood and is sensitive to the presence of hemozoin micro-crys...

    BACKGROUND: Ganglioneuroma is a rare tumour of neural crest origin, which arises from maturation of a neuroblastoma. While previously considered to be non-functioning, they are now known to be frequently endocrinologically active. AIMS AND METHODS: We report a case of a massive retroperitoneal ganglioneuroma presenting with small bowel obstruction in an adult, 18 years after initial diagnosis. Urinary dopamine levels were elevated, but other catecholamines were within normal limits. This is the first report in the English-language literature of a retroperitoneal ganglioneuroma presenting with or causing intestinal obstruction. We also review the metabolic, radiological, and histological features of these tumours. Relevant publications were identified from a Medline search using the MeSH headings \\'ganglioneuroma\\

    Most rural clinics across the country have limited facilities to provide state-of-the-art medical services. The availability of enabling technologies, such as telecommunication networks, multimedia workstations, and telemedicine systems which provide medical services to patients without requiring them to travel from their cities represents a great step in patient care. In previous work, we have developed a distributed software for remote consultation and diagnosis (RCD) in a Global PACS environment over the Internet. The RCD system has been designed and tested on DEC and SUN workstations. In this paper, we present a Unix-PC based platform to implement the RCD over a standard telephone line and Serial Line Internet Protocol (SLIP). The Unix-PC platform offers an inexpensive option for telemedicine workstations in rural clinics, where no Internet is available. If an Internet connection is available at the rural clinic, full RCD multimedia services are possible. The Unix-PC platform has been developed by using Linux, a Unix-like operating system available from several public sites over the Internet. We call the system PC-PACS. The PC-PACS workstation has been tested from different rural sites by connecting the Unix-PC system to the Internet through SLIP. Once the system is connected, RCD sessions have been performed between the Unix- PC platform and SUN workstations. The tests have included diagnosis on radiology and pathology images. A separate telephone line for voice communications during the RCD session is required. This paper describes performance tests for the PC-based workstation and the RCD system over SLIP and Ethernet interfaces. Results show acceptable performance of the workstation and the RCD software.

    Hyponatraemia (defined as a serum sodium concentration <136 mmol\\/L) is the most frequently encountered electrolyte disturbance in clinical practice. It is classified according to volume status (hypovolaemia, hypervolaemia or euvolaemia), reflecting the relative proportions of water and sodium within the body. The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is the most common cause of euvolaemic hyponatraemia. Although hyponatraemia is associated with poor prognosis and increased length of hospital stay, it is often poorly managed and sometimes underdiagnosed and undertreated. This article provides an overview of the frequency, pathophysiology and complications associated with this common clinical condition.

    In resource-limited settings, tuberculosis (TB) is often diagnosed by non-physicians using the acid-fast bacilli (AFB) smear only. This study examines the diagnostic accuracy of various clinicians using patient-risk history, radiography and AFB smear. A total of 321 physicians, nurses and medical students evaluated 22 profiles of TB suspects and quantified their clinical suspicion (1-99%). Culture results determined diagnostic accuracy. Overall, high-level physician training may not be required; nurses working on TB, given radiograph readings, were as accurate as TB physicians and more accurate than other physicians and clinicians. By considering clinical findings with smear results, TB specialists were significantly more accurate than smear results alone. PMID:19383202

    2016-01-01

    BACKGROUND Black raspberries (BRB) inhibit a broad range of cancers in preclinical models, including in vivo models of oral, esophageal, colon, breast and skin cancer. Promising preclinical results have led to clinical evaluations in cancer patients or patients at increased risk for cancer development. OBJECTIVE To summarize clinical investigations targeting cancer or precancerous lesions with BRB and discuss future directions. METHODS A thorough literature search was conducted through December 1, 2015 to identify all published studies evaluating BRB in cancer focused clinical trials. RESULTS Research investigating BRB in clinical settings report positive effects on preneoplastic lesions or cancers of the oral cavity, esophagus and colon. BRB treatment resulted in: histologic regression of oral intraepithelial neoplasia associated with improved histologic grade and significantly reduced loss of heterozygosity at tumor suppressor gene loci, modulated genes linked to RNA processing and growth factor recycling; in the colon, BRB inhibited FAP-associated polyp progression, demethylated tumor suppressor genes and improved plasma cytokine profiles; in Barrett’s patients, BRB consumption increased tissue levels of GST-pi and decreased 8-isoprostane, a marker of lipid peroxidation/oxidative stress. CONCLUSIONS The precise dose, duration and optimum mode of BRB delivery for cancer inhibition remains to be fully elucidated. Common themes across studies support that BRB are anti-proliferative, anti- inflammatory, reduce oxidative stress and restore tumor suppressive activity. Future directions are included in the conclusions section.

The aim of the current study was to assess HRQOL in a group of patients with Dual Diagnosis compared to two other non-comorbid groups and to determine what clinical factors are re...

  13. Magnetic resonance imaging in clinical diagnosis of dementia

    International Nuclear Information System (INIS)

    Dementing disorders belong to the most frequent neuropsychiatric diseases of the elderly population with prevalence rates of 5% in the 75 year old, but more than 10% in subjects older than 80 years. It is broadly accepted that the dementias are not caused by a single etiological factor but are attributed to a variety of different disease processes that affect the brain either directly or indirectly. According to pathoanatomic studies, two thirds of all dementias are caused by Alzheimer's disease (AD). Early recognition and differential diagnosis, which represent an important prerequisite for an optimized therapy, can be facilitated considerably by neuroimaging as well as by molecular biological findings. Therapeutic approaches include general medical management, psychosocial interventions as well as pharmacotherapy of cognitive and non-cognitive deficits. In general, early intervention using a combination of different therapeutic measures is recommended. In future, structural and functional neuroimaging might not only be used for diagnostic purposes but also to objectify and monitor the effect of treatment on relevant brain structures (orig.)

  14. CT scanning in pediatric head trauma: correlation of clinical features with CT scan diagnosis

    International Nuclear Information System (INIS)

    A retrospective review was conducted on 205 cases of pediatric head trauma for which cranial computed tomography scans were done at the Makati Medical Center, to determine which clinical features might positively predict an abnormality on CT scan. The clinical findings of loss of consciousness, GCS < 12, vomiting headache, seizures, and focal abnormalities on Neurologic Examination were significantly associated with abnormal findings on CT scan. However, a significant discrepancy does exist as to how accurately clinical findings do in fact predict normal and abnormal CT scan findings. Such a discrepancy allows us to conclude that a more liberal use of CT Scanning in cases of pediatric head trauma must be stressed to insure proper diagnosis. This study shows that when a patient presents with the aforementioned positive signs and symptoms, or with a focal neurologic deficit, or in combination, a 60-100 % positive prediction of abnormal CT Scan can be made. However, prediction of normal CT Scan is only 0-40%. (Author)

    Iron deficiency anemia is the most common cause of anemia in all age groups. Idiopathic pulmonary hemosiderosis is an extremely rare etiology of iron deficiency anemia seen predominantly in the pediatric population. Idiopathic pulmonary hemosiderosis is characterized by the triad of symptoms consisting of iron deficiency anemia, diffuse pulmonary infiltrates, and hemoptysis. The clinical presentation is extremely variable, and all three symptoms may not always be seen. Due to the rarity of the disease and the variability in clinical presentation, diagnosis is usually delayed. Early diagnosis and treatment with corticosteroids prevents further episodes of recurrent alveolar hemorrhage and improves the clinical outcome. Hence, a high index of suspicion is required for the diagnosis of this condition in young patients presenting with severe iron deficiency anemia and diffuse pulmonary infiltrates. We report a toddler with idiopathic pulmonary hemosiderosis whose initial clinical presentation was severe iron deficiency anemia. PMID:23362597

    Full Text Available Brucellosis is a zoonotic infection and has endemic characteristics. Neurobrucellosis is an uncommon complication of this infection. The aim of this study was to present unusual clinical manifestations and to discuss the management and outcome of a series of 18 neurobrucellosis cases. Initial clinical manifestations consist of pseudotumor cerebri in one case, white matter lesions and demyelinating syndrome in three cases, intracranial granuloma in one case, transverse myelitis in two cases, sagittal sinus thrombosis in one case, spinal arachnoiditis in one case, intracranial vasculitis in one case, in addition to meningitis in all cases. Eleven patients were male and seven were female. The most prevalent symptoms were headache (83% and fever (44%. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

  17. Neuroimaging supports the clinical diagnosis of methanol poisoning

    International Nuclear Information System (INIS)

    In addition to visual loss, methanol intoxication can cause brain damage that is revealed by neuroimaging. We report on a 34-year-old man whose visual acuity deteriorated dramatically during his journey round the world, shortly after an evening with excessive alcohol consumption. Two months after the start of visual disturbances he returned to Finland. At examination, poor visual acuity and glaucomatously cupped pale optic discs were detected. The history and clinical findings indicated possible methanol intoxication, which was supported by both CT and MRI. The MRI findings are discussed in the light of the MRI appearance of the pallidum nuclei among patients of different age groups. (orig.)

    1989-01-01

    Perineurial cysts are sometimes space-occupying cystic dilatations of the lumbo-sacral nerve roots at or distal to the junction of the posterior root and the dorsal ganglion. The wall is composed of perineurium and neural tissue. We report on 2 cases of upper sacral perineurial cysts with their computed tomography and myelography findings. Indication for operation is discussed: perineurial cysts should only be operated on if their clinical symptoms are clearly attributable to them and other causes like degeneration of the lumbar spine can be excluded.

    BACKGROUND: The National Institute for Health and Clinical Excellence (NICE) guidelines recommend a timeline of 6 weeks from referral to neurology consultation and then 6 weeks to a diagnosis of multiple sclerosis (MS). OBJECTIVES: We audited the clinical management of all new outpatient referrals diagnosed with MS between January 2007 and May 2010. METHODS: We analysed the timelines from referral to first clinic visit, to MRI studies and lumbar puncture (LP) (if performed) and the overall interval from first visit to the time the diagnosis was given to the patient. RESULTS: Of the 119 diagnoses of MS\\/Clinically Isolated Syndrome (CIS), 93 (78%) were seen within 6 weeks of referral. MRI was performed before first visit in 61% and within 6 weeks in a further 27%. A lumbar puncture (LP) was performed in 83% of all patients and was done within 6 weeks in 78%. In total, 63 (53%) patients received their final diagnosis within 6 weeks of their first clinic visit, with 57 (48%) patients having their diagnosis delayed. The main rate-limiting steps were the availability of imaging and LP, and administrative issues. CONCLUSIONS: We conclude that, even with careful scheduling, it is difficult for a specialist service to obtain MRI scans and LP results so as to fulfil NICE guidelines within the optimal six-week period. An improved service would require MRI scans to be arranged before the first clinic visit in all patients with suspected MS.

  1. Applications of PET CT in clinical practice: Present and future

    Science.gov (United States)

    Costa, Durval Campos

    2007-02-01

    Radionuclide imaging and specially positron emission tomography (PET) has already demonstrated its benefits in three major medical subjects, i.e. neurology, cardiology and particularly clinical oncology. More recently the combination of PET and X-ray computed tomography (CT) as PET-CT led to a significant increment of the already large number of clinical applications of this imaging modality. This "anatomy-metabolic fusion" also known as Metabolic Imaging has its future assured if we can: (1) improve resolution reducing partial volume effect, (2) achieve very fast whole body imaging, (3) obtain accurate quantification of specific functions with higher contrast resolution and, if possible, (4) reduce exposure rates due to the unavoidable use of ionizing radiation.

    Full Text Available Introduction & Background: Only 12 years ago the first report on pachymeningeal gadolinium enhance-ment in low-pressure headaches appeared in the lit-erature. Intracranial hypotension is a result of low CSF volume caused by either spontaneous or postoperative leakage. The syndrome has been reported to occur after head trauma, a tear in a spinal nerve root sheath, perineural cyst, or spinal arachnoid diverticulum. Iatrogenic causes include lumbar puncture or overdraining ventricular or spinal shunts. Spontaneous intracranial hypotension is thought to result from rupture of a spinal arachnoid membrane that allows CSF passage into the subdural or epidural space. It is typically not attributable to a major traumatic event or prior diagnostic or therapeutic intervention; however, intracranial hypotension may be associated with a history of minor trauma such as sports activities or severe coughing. Diffuse pachymeningeal enhancement is thought to reflect the Monro-Kellie rule, which describes the inverse relationship of CSF volume and intracranial blood volume within the rigid confines of the skull. This reflex mechanism protects nervous tissue by maintaining a constant buffer (ie, blood or CSF subjacent to its bony covering. Though this principle was described for intracranial processes and helps to explain the reason for intracranial pachymeningeal enhancement, it can also be applied to the bony spinal canal. Explaining pachymeningeal enhancement in the spine becomes more difficult because the hypervascular outer dural layer covering the brain does not extend to cover the spine, and the single layer of dura that does cover the spine is relatively avascular. Perhaps reports of pachymeningeal enhancement along the spinal canal in intracranial hypotension more accurately reflect prominent epidural venous engorgement. In all cases of intracranial hypotension reported in the literature, patients presented with headaches. These headaches are typically

    2015-06-01

    Full Text Available The paper describes a 44-year-old male patient with an about 6-year history of hypertrophic pachymeningitis. The major clinical symptoms were characterized by headache, exophthalmos, and blindness in one eye. The data for differential diagnosis of the disease are given. The current literature on the clinical manifestations of hypertrophic pachymeningitis, its differential diagnosis, and the results of magnetic resonance imaging (MRI is reviewed. Diagnostic difficulties at the stage of a clinical observation are due to the nonspecificity of neurological manifestations and the need for a comprehensive examination to detect a somatic disease. MRI can diagnose the disease-specific phenomenon of damage to the meninges, which calls for further careful differentiation. Clinicians must be familiar with alternative differential diagnosis, as a rapid specific therapeutic approach will help avoid long-term or irreversible neurological complications.

    2014-06-01

    Full Text Available Juvenile Xanthogranulomas (JXG are benign proliferative disorders of non-Langerhans histiocytes, which present in children as multiple, self-limited, cutaneous lesions. The extracutaneous manifestations of JXG are uncommon, and isolated JXG involving the spinal column is extremely rare. We report here a case of isolated juvenile xanthogranuloma in thoracic spine correctly diagnosed intraoperatively on crush smear cytology and later confirmed by histopathological and immunohistochemical studies. This case report draws attention to the fact that isolated xanthogranuloma should be considered among possible diagnoses of spinal tumor in children. Also, since the long term survival depends on complete surgical resection, a correct intraoperative diagnosis is extremely important for optimal management and prognosis of the patient.

    2016-07-01

    We present a case report of a two year old child with an enlarging neck mass over a two year period. Her work-up included blood investigations, radiological imaging and fine needle aspirations which were non-diagnostic. At age 4 she had excision of her neck mass and histopathologic examination revealed unicentric Castleman's disease. This is one of the youngest reported cases in the literature and highlights the need to include CD in the differential diagnosis of neck masses in young children. Castleman's disease (CD) is a rare disease of benign lymph node enlargement which most commonly occurs in adults. While the multi-centric variant is associated with HIV and HHV-8 infection, the aetiology of unicentric disease remains uncertain. PMID:27260588

    Ebola virus disease (EVD) is a severe multisystem disease. Prehospital personnel, hospitals, and clinicians must be prepared to provide care for patients with EVD, with special attention to rigorous infection control in order to limit the spread of infection. Children with EVD are an especially challenging population, as the initial symptoms are nonspecific and difficult to differentiate from several common infections. For children presenting with a syndrome consistent with EVD, it is extremely important that healthcare workers identify epidemiologic risk factors, such as recent travel to an affected country or exposure to a patient with suspected or known EVD. Given the high morbidity and mortality of this disease, clinical efforts should focus on early diagnosis, appropriate infection control, and supportive care. PMID:27328168

    OBJECTIVE: Globally approximately 60 cases of C1q deficiency have been described with a high prevalence of Systemic Lupus Erythematosus (SLE). So far treatment has been guided by the clinical presentation rather than the underlying C1q deficiency. Recently, it was shown that C1q production can be...... restored by allogeneic hematopoietic stem cell transplantation. Current literature lacks information on disease progression and quality of life of C1q deficient persons which is of major importance to guide clinicians taking care of patients with this rare disease. METHODS: We performed an international...... survey, of clinicians treating C1q deficient patients. A high response rate of >70% of the contacted clinicians yielded information on 45 patients with C1q deficiency of which 25 are published. RESULTS: Follow-up data of 45 patients from 31 families was obtained for a median of 11 years after diagnosis...

    This paper reviewed the recent progress in the field of electrocardiogram (ECG) compression and compared the efficiency of some compression algorithms. By experimenting on the 500 cases of ECG signals from the ECG database of China, it obtained the numeral indexes for each algorithm. Then by using the automatic diagnostic program developed by Shanghai Zhongshan Hospital, it also got the parameters of the reconstructed signals from linear approximation distance threshold (LADT), wavelet transform (WT), differential pulse code modulation (DPCM) and discrete cosine transform (DCT) algorithm. The results show that when the index of percent of root-mean-square difference(PRD) is less than 2.5%, the diagnostic agreement ratio is more than 90%; the index of PRD cannot completely show the damage of significant clinical information; the performance of wavelet algorithm exceeds other methods in the same compression ratio (CR). For the statistical result of the parameters of various methods and the clinical diagnostic results, it is of certain value and originality in the field of ECG compression research.

    Full Text Available Abstract Background We set out to define the relative prevalence and common presentations of the various aetiologies of headache within an ambulant HIV-seropositive adult population in Kampala, Uganda. Methods We conducted a prospective study of adult HIV-1-seropositive ambulatory patients consecutively presenting with new onset headaches. Patients were classified as focal-febrile, focal-afebrile, non-focal-febrile or non-focal-afebrile, depending on presence or absence of fever and localizing neurological signs. Further management followed along a pre-defined diagnostic algorithm to an endpoint of a diagnosis. We assessed outcomes during four months of follow up. Results One hundred and eighty patients were enrolled (72% women. Most subjects presented at WHO clinical stages III and IV of HIV disease, with a median Karnofsky performance rating of 70% (IQR 60-80. The most common diagnoses were cryptococcal meningitis (28%, n = 50 and bacterial sinusitis (31%, n = 56. Less frequent diagnoses included cerebral toxoplasmosis (4%, n = 7, and tuberculous meningitis (4%, n = 7. Thirty-two (18% had other diagnoses (malaria, bacteraemia, etc.. No aetiology could be elucidated in 28 persons (15%. Overall mortality was 13.3% (24 of 180 after four months of follow up. Those without an established headache aetiology had good clinical outcomes, with only one death (4% mortality, and 86% were ambulatory at four months. Conclusion In an African HIV-infected ambulatory population presenting with new onset headache, aetiology was found in at least 70%. Cryptococcal meningitis and sinusitis accounted for more than half of the cases.

  13. Spectrum of clinical presentation and surgical management of intestinal tuberculosis at tertiary care hospital

    International Nuclear Information System (INIS)

    Background: Tuberculosis can involve gastrointestinal tract anywhere from mouth to anus, the peritoneum and pancreato biliary system. It has varied clinical presentations sometimes mimicking other common abdominal diseases. Tuberculosis continues to be a major problem especially in developing countries, being responsible for 7 - 10 million new cases and 6 per cent of deaths worldwide annually. Objective was to assess and evaluate various clinical presentations and management of intestinal tuberculosis at Liaquat University Hospital, Jamshoro/Hyderabad. Methods: This 3-year descriptive study was conducted on patients with diagnosed intestinal tuberculosis (by histopathology) in Surgical Unit-I, from January 2006 to December 2008. Detailed history and clinical examination was performed in all the cases. Investigations like Blood CP and ESR, Urea, RBS Electrolytes, Serum A/G Ratio, Ultrasound abdomen, X-Ray chest and abdomen were carried out in all the cases while barium meal, follow through and CT Scan abdomen were performed in selected cases. Preoperative assessment of anatomical site and variety of lesions were also noted. Results: A total of 60 patients with diagnosis of intestinal tuberculosis were admitted and operated. Diagnosis was confirmed by histopathology. Among these, 28 (46.7%) were male, and 32 (54.1%) were female. Variable clinical presentations were seen. Majority of patients (46, 76.7%) had abdominal pain, 26 (43.3%) had vomiting; abdominal distension was seen in 22 (36.7%) cases, diarrhoea and constipation in 16 patients (26.7%) and abdominal mass in 14 patients (23.3%). Majority of patients had ulcerostenotic type of tuberculosis. Single stricture of ileum was seen in 15 (25%) while multiple strictures were seen in 13 (21.7%). Ileal perforation was seen in 6 (10%) patients. Weight lo ss was seen in 40 (66.7%) patients, fever 36 (60%), night sweats 30 (50%), anorexia in 30 (50%) and pulmonary tuberculosis in 18 (30%) patients. Resection and

    Full Text Available OBJECTIVE To study the clinical and histopathological presentation of ovarian masses. METHOD Hospital based retrospective study done on 200 patients in the Department of Gynaecology, Gandhi Hospital, Secunderabad, who are clinically and sonologically diagnosed to have ovarian masses during the period of January 2014 to September 2015. RESULTS The prevalence of ovarian masses in our study was 0.6%. Among the 200 cases, 60.5% were neoplastic and 39.5% were non-neoplastic. Among neoplasms 90% were benign, 8.26% malignant and 1.65% borderline. Serous cystadenoma was the commonest benign tumor (55% followed by Mucinous (27.5% and Dermoid (15.5%. Most common malignant ovarian tumor was Serous cystadenocarcinoma (60%. CONCLUSION Ovarian neoplasms have twice the incidence of non-neoplasms. Maximum incidence of malignancy is in between 40-49 years of age group. Non-specific abdominal symptoms should be given more importance, as it may be the only clue to the underlying malignancy. So effective clinical, biochemical and radiological diagnosis helps in early intervention to increase the survival rates in malignancy. Sixty million people are affected with glaucoma worldwide and more than 20 million have PACG. Of these more than 5 million with PACG are blind, which is twice more than POAG. Early detection and timely treatment with Nd:YAG laser iridotomy and associated complications determine visual outcome.

  19. Giant intracranial aneurysms: development, clinical presentation and treatment

    International Nuclear Information System (INIS)

    The natural history of giant intracranial aneurysms are grave. More than 50% of patients suffer from rupture of these aneurysms and mortality is >60% in 2 years. Modern technology and advancement of knowledge in neurosurgery and interventional neuroradiology have altered its natural course for the better. As many reports have shown, the majority of these aneurysms can be treated either by surgery or by endovascular approach, even though morbidity is higher than when treating smaller aneurysms. Certain aneurysms are more suitable to direct surgical clipping and others may have better chances of good clinical outcome by endovascular treatment. It is imperative to analyse the location, morphology, hemodynamics and circulation of normal brain of each aneurysm before the mode of treatment is decided. Needless to say, the individual patient's age, neurological and medical condition should be considered. For endovascular treatment, application of each technique, endosaccular occlusion or parent artery occlusion depends on the aneurysm location and geometry as well as its pathology. Several reports indicated that clinical outcome is better in patients treated by parent artery occlusion since it eliminates any blood flow to the aneurysm and it provides a more effective reduction of the mass effect. However, not all parent arteries can be sacrificed. In addition, endosaccular treatment is effective in preventing haemorrhage if the aneurysm is not re-canalised. It is also demonstrated that symptoms of mass effect can be reversed by endosaccular coiling. The patients who are treated this way should be closely monitored for re-canalisation

    Full Text Available Abstract Background To recognize ocular presentations in cranial venous sinus thrombosis (CVST which were easy to be misdiagnosis. Design Retrospective study. Methods Review clinical informations including general informations, general performances, and ocular presentations of 118 inpatients with CVST in the general hospital of chinese people's liberation army during 2005-2009. Main Outcome Measures The ocular symptoms as the initial onset presentations or simultaneous phenomenon among different onset type patients were analyzed. Results Of all the CVST patients, 21.2% (25/118 presented with ocular symptom as the initial presentation, 30.5% (36/118 presented with ocular symptom as well as the other symptoms, and 48.3% (57/118 presented with non-ocular symptoms as the initial onset. The CVST patients were divided into 3 groups according to the onset type. There was no marked statistical significance among groups. The most common major complaints were blurring and degeneration of acute vision, accounting for 85.9% (61/71 of all abnormal ocular chief complaints. The most common objective sign in eyes was papilloedema, accounting for 48.3% (57/118 in this group of CVST patients. About 22.4% (13/58 showed acute vision deterioration at 1-year follow-up, due to optic atrophy. Conclusions As ophthalmologists, we should master the onset characteristics and clinical manifestations of CVST. Early diagnosis and treatment is very important for the prevention of vision deterioration, especially for patients with ocular syndrome as the initial onset syndrome. For isolated agnogenic intracranial hypertension, we should consider the possibility of CVST.

The aim of this study is to define clinical predictors related to inappropriate or delayed diagnosis of Stanford type A AAD.We conducted a retrospective analysis of 127 consecutive patients with type A AAD who presented to the ER within 12 h of symptom onset (age: 69.0 ± 15.4 years, male/female = 49/78. An inappropriate initial diagnosis (IID was considered if AAD was not included in the differential diagnosis or if chest computed tomography or echocardiography was not performed as initial imaging tests. Clinical variables were compared between IID and appropriate diagnosis group. The time to final diagnosis (TFD was also evaluated. Delayed diagnosis (DD was defined as TFD > third quartile. Clinical factors predicting DD were evaluated in comparison with early diagnosis (defined as TFD within the third quartile. In addition, TFD was compared with respect to each clinical variable using a rank sum test.An IID was determined for 37% of patients. Walk-in (WI visit to the ER [odds ratio (OR 2.6, 95% confidence interval (CI = 1.01-6.72, P = 0.048] and coronary malperfusion (CM, OR = 6.48, 95% CI = 1.14-36.82, P = 0.035 were predictors for IID. Overall, the median TFD was 1.5 h (first/third quartiles = 0.5/4.0 h. DD (>4.5 h was observed in 27 cases (21.3%. TFD was significantly longer in WI patients (median and first/third quartiles = 1.0 and 0.5/2.85 h for the ambulance group vs. 3.0 and 1.0/8.0 h for the WI group, respectively; P = 0.003. Multivariate analysis revealed that WI visit was the only predictor for DD (OR = 3.72, 95% CI = 1.39-9.9, P = 0.009. TFD was significantly shorter for appropriate diagnoses than for IIDs (1.0 vs. 6.0 h, respectively; P < 0.0001.WI visit to the ER and CM were predictors for IID, and WI was the only predictor for DD in acute type A AAD in the community hospital.

    Full Text Available The incidence of bilateral testicular cancer is 5% in the total cohort of patients. Synchronous and metachronous testicular cancers are detected in 1-2 and 3% of cases, respectively. The standard treatment for testicular cancer is orchifuniculectomy and that for synchronous or metachronous cancer is organ-saving treatment, testectomy.The paper describes a clinical case of multiple primary metachronous testicular cancer. A 24-year-old patient underwent surgery (orchifuniculectomy and received 4 courses of BEP polychemotherapy for embryonal carcinoma of the left testicle at the P.A. Herzen Moscow Oncology Research Institute. After 55 months, a dynamic control examination diagnosed a 9-mm tumor in his single right testis that was thereafter resected. Its histological examination revealed embryonal carcinoma with solitary structures in the immature teratoma. Following 22 months, a control examination showed a recurrence of the disease, for which orchifuniculectomy of the single right testis, followed by hormone replacement therapy, was performed. The follow-up period was 80 months; no recurrence is now observed.

    Full Text Available Abstract Background In Lithuania, the vaccination coverage against pertussis is high. Nevertheless, there is a significant increase in pertussis cases in fully immunized children. The aim of our study was to determine the frequency of classical symptoms of laboratory confirmed pertussis and describe its epidemiology in children fully vaccinated against pertussis. Methods From May to December 2001, 70 children aged 1 month to 15 years, suffering from prolonged cough were investigated in the Centre of Paediatrics, Vilnius University Children's Hospital. The collected information included personal data, vaccination history, clinical symptoms of the current illness, and treatment before hospitalization. At the admission to the hospital blood samples were taken from all studied children for Bordetella pertussis IgM and IgA. Results A total of 53 (75.7% of the 70 recruited patients with prolonged cough showed laboratory evidence of pertussis. 32 of them were fully vaccinated with whole cell pertussis vaccine (DTP. The age of fully vaccinated patients varied from 4 to 15 years (average 10.9 ± 3.1; median 11. The time period between the last vaccination dose (fourth and the clinical manifestation of pertussis was 2.6–13 years (average 8.9 ± 3.0; median 9. More than half of the children before the beginning of pertussis were in contact with persons suffering from long lasting cough illness in the family, school or day-care center. The mean duration from onset of pertussis symptoms until hospitalization was 61.4 ± 68.3 days (range, 7 to 270 days; median 30. For 11 patients who had had two episodes (waves of coughing, the median duration of cough was 90 days, and for 21 with one episode 30 days (p Conclusion Fully vaccinated children fell ill with pertussis at the median of 11 years old, 9 years following pertussis vaccination. More than half of the children could catch pertussis at home, at school or day-care center. Clinical picture of pertussis in

    We present the case of a 62 years old patient, with multiple associated tares, which was operated in emergency for an Amyand's hernia. The appendix was perforated and generated a big pussy collection (aprox. 200 ml) in the hernia sac. The impossibility of mobilization of the appendix, which was just 2/3 in the hernia sac, made us perform a median laparotomy for safety reasons. The position and fixation of the cecum made impossible the exteriorization of the appendix in the hernia sac. The postoperative evolution, under a complex supervision, was favorable. Due to the rarity of the clinical entity, of the specific issues and of the literature review, we decided to communicate the clinical observation. PMID:22844840

    In this study we reviewed the clinical features, diagnoses and treatments of 232 cases of nasal bone fracture cases treated at our department from January 1994 to June 2000. A marked predominance of males in the age range of 10-29 years was noted. Analysis of the causes of the nasal fractures were attributed to fighting (66 cases), traffic accidents (64 cases), sports (56 cases) and others (46 cases). The external appearance of nasal fractures were divided into 5 types, 85 cases of the displacement type, 27 cases of the depressed type, 32 of the mixed type, 56 of the non-deformation type and 32 of the unclassified type because of facial swelling. The sensitivity of conventional X-ray examination in identifying nasal fractures was 75.6%. Computed tomography scan (CT scan) was performed in 196 patients and showed that the middle and lower portions of nasal bones were fractured more easily than those of the upper portion. Nasal septum fracture occurred in 22 cases (11.2%). Other facial fractures combined with nasal fracture were found in 40 cases (20.4%). The type of combined fracture depended on the cause of the injury, for example, the combination of nasal and blow-out fracture was often caused by fighting, and many combined fractures of more than two facial bones resulted from traffic accidents. A total of 83 patients (35.8%) received reduction of the nasal bone fractures under general anaesthesia. The measurement of irradiation of each radiological examination revealed that the exposed dose of the newest model CT was similar to that of the conventional X-ray examination and tomography.

  10. Aerosolized pentamidine: Effect on diagnosis and presentation of Pneumocystis carinii pneumonia

    International Nuclear Information System (INIS)

    The objective of this study was to determine the effect of previous aerosolized pentamidine therapy on diagnosis and presentation of Pneumocystis carinii pneumonia. This was a retrospective study of fifty-two consecutive patients with P. carinii pneumonia and underlying infection with the human immunodeficiency virus (HIV) who had bronchoscopy. Twenty-one patients who were on aerosolized pentamidine therapy served as the study group. Thirty-one patients who had not received the drug served as the control group. The yield of bronchoalveolar lavage for P. carinii pneumonia was 62% for the study group and 100% for the control group (P less than 0.05). This lower yield was significant for the subset of patients having their first episode of P. carinii pneumonia. The yield of transbronchial biopsy was similar for both groups of patients (81% compared with 84%). The yield of bronchoscopy was not influenced by use of zidovudine. Review of lavage specimen slides suggested that there may be fewer organisms present in patients receiving aerosolized pentamidine. An atypical roentgenographic presentation of upper lobe predominant infiltrates was seen in 38% of the study patients and 7% of the control patients. In addition, pneumothoraces and cystic changes were also frequently seen in the study patients. Gallium scans, when done, were also atypical in the study group. Markers of the severity of disease, however, were similar in both groups. The yield of bronchoalveolar lavage for P. carinii pneumonia in HIV-infected patients is lower in patients receiving aerosolized pentamidine. Unusual roentgenographic presentations and atypical gallium scans are also found in this setting

  11. Present status of clinical deployment of glucokinase activators.

    Glucokinase is one of four members of the hexokinase family of enzymes. Its expression is limited to the major organs (such as the pancreas, liver, brain and the gastrointestinal tract) that are thought to have an integrated role in glucose sensing. In the liver, phosphorylation of glucose by glucokinase promotes glycogen synthesis, whereas in the β-cells, it results in insulin release. Studies of glucokinase-linked genetically-modified mice and mutations in humans have illustrated the important roles played by glucokinase in whole-body glucose homeostasis, and suggest that the use of pharmacological agents that augment glucokinase activity could represent a viable treatment strategy in patients with type 2 diabetes. Since 2003, many glucokinase activators (GKAs) have been developed, and their ability to lower the blood glucose has been shown in several animal models of type 2 diabetes. Also, we and others have shown in mouse models that GKAs also have the effect of stimulating the proliferation of β-cells. However, the results of recent phase II trials have shown that GKAs lose their efficacy within several months of use, and that their use is associated with a high incidence of hypoglycemia; furthermore, patients treated with GKAs frequently developed dyslipidemia. A better understanding of the role of glucokinase in metabolic effects is required to resolve several issues identified in clinical trials. PMID:25802718

    Leishmaniasis is a disease with worldwide increasing incidence, which in Germany is almost exclusively observed in patients who have travelled to classical endemic regions such as the Mediterranean basin. Cause of the disease is an infection with protozoan parasites of the genus Leishmania, which are transmitted by sand flies and replicate intracellularly within mammalian hosts. Depending on the inoculated parasite (sub-) species and the immune status of the host, a local cutaneous, diffuse cutaneous, mucocutaneous or visceral form of leishmaniasis will develop. Cutaneous leishmaniasis, which frequently appears only weeks after the bite of a sand fly, starts with the formation of a papule, which subsequently can turn into a skin ulcer. The latter may heal spontaneously after months leaving behind a scar or persist as chronic, non-healing cutaneous leishmaniasis. If cutaneous leishmaniasis is suspected, a sterile skin biopsy followed by appropriate diagnostic measures in a specialized laboratory to identify the pathogen should be performed. For the decision on the type of therapy, several clinical parameters (e.g. number and localization of lesions, immune status) and, most importantly, the underlying parasite (sub-) species need to be considered. Therapy can consist of a variety of topical measures or systemic drug treatment. A modern and safe vaccine does not yet exist. PMID:22422121

    Full Text Available Diabetes mellitus (DM is a global epidemic followed by late complications as diabetic polyneuropathy (DPN and diabetic foot syndrome, leading to appreciable social and economic consequences. Virtually all patients with DM develop DPN in different periods. There is a clear correlation between the presence and magnitude of painful DPN and the duration of DM and the level of glycosylated hemoglobin and the severity of DPN. In spite of the abundance of theories of the development of DPN, its main identified pathogenetic factor is hyperglycemia. The literature gives no universal classification due to the variability of clinical symptoms. The main goals of treatment are to affect the pathogenesis of the disease and to prescribe symptomatic medications. The pathogenetic treatment of DPN includes compensation for carbohydrate metabolism and use of neurometabolic drugs. Pain from DPN may be controlled with antidepressants, anticonvulsants, local anesthetics and opioid analgesics. Although much evidence for the pathogenesis of peripheral nervous system injury has been recently accumulated, a universal standard for the effective therapy of DPN and the follow-up of these patients has not yet been developed.

    Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

    The oto-spondylo-mega-epiphyseal-dysplasia (OSMED) phenotype is an autosomal recessive trait that is a skeletal dysplasia with the hallmark findings of limb shortening, multiple skeletal and radiological abnormalities, mid-face hypoplasia with a flat nasal bridge, small upturned nasal tip, and sensorineural hearing loss. A 3.5-year-old girl born to consanguineous Turkish parents had characteristic facial features at birth: mid-face hypoplasia, mild hypertelorism, upslanting palpebral fissures, prominent supraorbital ridges, depressed nasal bridge, small upturned nasal tip, long philtrum, and micrognathia. Radiological examination at three years of age revealed large flaring metaphyses and wide flat epiphyses. The humerus and femur showed the characteristic dumbbell shape. She had bilateral hearing loss with no ophthalmologic findings. There is continuing debate over the clinical overlap and differential diagnosis of OSMED syndrome. The patient was examined considering Weissenbacher-Zweymuller, Stickler type 3, Marshall syndrome, and Kniest dysplasia as possible differential diagnoses. We believe that the presented patient clinically manifested features of OSMED syndrome. We would like to point out that the management of OSMED calls for a coordinated multidisciplinary approach.

    Full Text Available Background: tumors of the ocular adnexa are a common cause of patient visits to the Ophthalmology consultation. An adequate clinical-pathological relationship is important for prognosis. Objective: to describe the correspondence between clinical and histopathological diagnosis of tumors of the ocular adnexa. Methods: a case series study was conducted in patients who underwent a histopathological study due to suspicion of malignancy treated at the Oculoplastic Service of the Ophthalmology Center of the Dr. Gustavo Aldereguía University General Hospital, from January 2014 to the same month of 2015. The variables analyzed were: age, skin color, type of tumor, correspondence between clinical and histopathological diagnosis and safety margin. Results: correspondence between clinical and histopathological diagnosis was 79.1 %. The 40-59 age group was the most affected, with a higher incidence in females. The most common location was the eyelid region in white patients. Benign lesions of the eyelid and conjunctiva predominated. Conjunctival carcinoma and basal cell carcinoma were the most common malignancies; the safety margin was 2.19 %. Conclusions: an adequate correspondence between presumptive and histopathological diagnosis was observed. The safety margin achieved was satisfactory.

  1. Primary biliary cirrhosis: Pathophysiology, clinical presentation and therapy.

    Purohit, Treta; Cappell, Mitchell S

    2015-05-01

    Primary biliary cirrhosis (PBC) is an autoimmune, slowly progressive, cholestatic, liver disease characterized by a triad of chronic cholestasis, circulating anti-mitochondrial antibodies (AMA), and characteristic liver biopsy findings of nonsuppurative destructive cholangitis and interlobular bile duct destruction. About 10% of PBC patients, however, lack AMA. A variant, called PBC-autoimmune hepatitis (AIH) overlap, is characterized by the above findings of PBC together with findings of elevated serum alanine aminotransferase, elevated serum immunoglobulin G, and circulating anti-smooth muscle antibodies, with liver biopsy demonstrating periportal or periseptal, lymphocytic, piecemeal necrosis. PBC is hypothesized to be related to environmental exposure in genetically vulnerable individuals. It typically occurs in middle-aged females. Prominent clinical features include fatigue, pruritis, jaundice, xanthomas, osteoporosis, and dyslipidemia. The Mayo Risk score is the most widely used and best prognostic system. Ursodeoxycholic acid is the primary therapy. It works partly by reducing the concentration and injury from relatively toxic bile acids. PBC-AIH overlap syndrome is treated with ursodeoxycholic acid and corticosteroids, especially budesonide. Obeticholic acid and fibrate are promising new, but incompletely tested, therapies. Liver transplantation is the definitive therapy for advanced disease, with about 70% 10-year survival after transplantation. Management of pruritis includes local skin care, dermatologist referral, avoiding potential pruritogens, cholestyramine, and possibly opioid antagonists, sertraline, or rifaximin. Management of osteoporosis includes life-style modifications, administration of calcium and vitamin D, and alendronate. Statins are relatively safe to treat the osteopenia associated with PBC. Associated Sjogren's syndrome is treated by artificial tears, cyclosporine ophthalmic emulsion to stimulate tear production; and saliva

    Aim. The aim of this work is to describe a case of immediate implant placement after extraction of the upper right first premolar, with the use of CAD/CAM technology, which allows an early digital impression of the implant site with an intraoral scanner (MHT 3D Progress, Verona, Italy). Case Report. A 46-year-old female was referred with a disorder caused by continuous debonding of the prosthetic crown on the upper right first premolar. Clinically, there were no signs, and the evaluation of the periapical radiograph showed a fracture of the root, with a mesial well-defined lesion of the hard tissue of the upper right first premolar, as the radiolucent area affected the root surface of the tooth. It was decided, in accordance with the patient, that the tooth would be extracted and the implant (Primer, Edierre implant system, Genoa, Italy) with diameter of 4.2 mm and length of 13 mm would be inserted. After the insertion of the implant, it was screwed to the scan abutment, and a scan was taken using an intraoral scanner (MHT 3D Progress, Verona, Italy). The scanned images were processed with CAD/CAM software (Exocad DentalCAD, Darmstadt, Germany) and the temporary crown was digitally drawn (Dental Knowledge, Milan, Italy) and then sent to the milling machine for production with a composite monoblock. After 4 months, when the implant was osteointegrated, it was not necessary to take another dental impression, and the definitive crown could be screwed in. Conclusion. The CAD/CAM technology is especially helpful in postextraction implant for aesthetic rehabilitation, as it is possible to immediately fix a provisional crown with an anatomic shape that allows an optimal healing process of the tissues. Moreover, the removal of healing abutments, and the use of impression copings, impression materials, and dental stone became unnecessary, enabling the reduction of the chair time, component cost, and patient's discomfort.

    Full Text Available INTRODUCTION Dystonia, as prolonged, involuntary muscle contraction, causes torsion, repetitive movements and abnormal body position. In so far only a part of body is affected by dystonic movement, it is the question of focal dystonia, which is called writer's cramp if the arm is involved. OBJECTIVE The objective of the study was to present the specific clinical features of patients with task-specific dystonia, who were diagnosed, treated and followed up at the Institute of Neurology, Clinical Center of Serbia, Belgrade. MATERIAL AND METHODS In the period 1995-2003, 30 patients with task-specific dystonia were treated at the Institute of Neurology, CCS, who met the adopted criteria for diagnosis. The severity of the diseases was tested by estimating the ability of patient to write the test sentence per time unit, as well as by means of scale for measuring different disabilities, ranging from 0-16 (Marsden-Fahn. Depression, anxiety and obsessiveness were tested by Beck's scale, Hamilton's depression and anxiety scale and Mousdly's obsessiveness scale. Thorough questionnaire focused on clinical details was also used. Besides descriptive statistics, data processing included analysis of variance and Kruskal-Wallis's test. RESULTS Thirty patients with diagnosis of task-specific dystonia were analyzed.

  11. Clinical consequences of the EI/MCS "diagnosis": two paths.

    Science.gov (United States)

    Staudenmayer, H

    1996-08-01

    There are two distinct paths down which patients "diagnosed" with environmental illness/multiple chemical sensitivities (EI/MCS) can travel. Along the first path, beliefs about low-level, multiple chemical sensitivities as the cause of physical and psychological symptoms are instilled and reinforced by a host of factors including toxicogenic speculation, iatrogenic influence mediated by unsubstantiated diagnostic and treatment practices, patient support/advocacy networks, and social contagion. Intrapsychic factors also reinforce this path through the motivational mechanism of factitious malingering, or unconscious primary and secondary gain, mediated through psychological defenses, particularly projection of cause of illness onto the physical environment. The second path involves restructuring distorted beliefs about chemical sensitivities. Explanations of the placebo effect, the physiology of the stress response, and the symptoms of anxiety and panic facilitate the direction of EI/MCS patients onto this path. A decision model is presented to discriminate among toxicogenic and psychogenic explanations of the EI/MCS phenomenon, based on appraisal of reaction and physiologic and cognitive responses during provocation chamber challenges under double-blind, placebo-controlled conditions. These studies have been helpful therapeutically for some patients in selecting the path that leads to wellness. This paper suggests how various therapeutic techniques can be employed with difficult patients. Often, supportive psychotherapy establishes a therapeutic alliance which facilitates cognitive therapy to restructure distorted beliefs. In the process of finding alternative explanations to chemical sensitivities, the etiology of symptoms is related to stressful life events, including childhood experiences which may have disrupted normal personality development and coping capacity. Furthermore, biological and physiological sequelae stemming from early, chronic trauma have been

    Full Text Available Abstract Background Excavated pulmonary metastasis are rare. We present two cases of excavated pulmonary nodules proved to be metastases from osteosarcoma and gallblader lymphoma. Case presentation The first one is 39-year-old man in whom cholecystectomy made the diagnosis of primary non-Hodgkin's lymphoma of the gallbladder. He presented in chest CT scan excavated nodules that had been biopsied and confirmed the diagnosis of non hodgkin lymphoma. He underwent 8 courses of chemotherapy CHOP 21 with complete remission. The second one is an 21 years old man who presented a right leg osteoblastic osteosarcoma with only excavated pulmonary nodules in extension assessment. He had 3 courses of polychemotherapy API (doxorubicin, platinum, and ifosfamide with partial response. Unfortunately, he died following a septic shock. Review of the literature shows that excavated pulmonary nodules as metastasis are rare but we should consider this diagnosis every time we are in front of a cancer. Chest computed tomography is the best diagnosis imaging that could make this diagnosis. Differential diagnosis between benign and malignant bullous lesions is important because surgical excision affects survival in some malignancies. Conclusions Although pulmonary nodules are the most common cancer metastasis, a differential diagnosis of a concurrent primary malignancy should always be considered every time we have excavated lesions, even in patients with known malignant disease. Thorough chest evaluation is important, as multiple primary malignancies may occur concomitantly.

    Full Text Available OBJECTIVE - To assess the incidence of fatal pulmonary embolism (FPE, the accuracy of clinical diagnosis, and the profile of patients who suffered an FPE in a tertiary University Hospital. METHODS - Analysis of the records of 3,890 autopsies performed at the Department of General Pathology from January 1980 to December 1990. RESULTS - Among the 3,980 autopsies, 109 were cases of clinically suspected FPE; of these, 28 cases of FPE were confirmed. FPE accounted for 114 deaths, with clinical suspicion in 28 cases. The incidence of FPE was 2.86%. No difference in sex distribution was noted. Patients in the 6th decade of life were most affected. The following conditions were more commonly related to FPE: neoplasias (20% and heart failure (18.5%. The conditions most commonly misdiagnosed as FPE were pulmonary edema (16%, pneumonia (15% and myocardial infarction (10%. The clinical diagnosis of FPE showed a sensitivity of 25.6%, a specificity of 97.9%, and an accuracy of 95.6%. CONCLUSION - The diagnosis of pulmonary embolism made on clinical grounds still has considerable limitations.

  14. Clinical and radiological diagnosis of chronic pneumonia in pneumoconiosis and dust bronchitis

    International Nuclear Information System (INIS)

    Clinical and radiologic symptomatology of chronic pneumonia is described for pneumoconiosis and chronic dust bronchitis. Combined X-ray methods of examination permit the physicians to discover this complication in dust diseases of the lungs in the presence of diffuse pneumosclerotic changes in 76.5+-3 % of cases. These data approach the values of chronic pneumonia incidence among the population. Chronic pneumonia diagnosis should be complex. If no less than 2 to 3 X-ray signs of the disease have been found simultaneously, the significance of radiologic diagnosis of chronic pneumonia in dust pathology of the lungs, rises. Radiologic examination, supported by clinical, anamnestic and laboratory data, allows one to differentiate chronic pneumonia from coniotuberculosis. Chest X-rays in dust pathology of the lungs, complicated by chronic pneumonia, should be carried out with regard to clinical indications

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

    Gruszauskas, Nicholas Peter

    The chances of surviving a breast cancer diagnosis as well as the effectiveness of any potential treatments increase significantly with early detection of the disease. As such, a considerable amount of research is being conducted to augment the breast cancer detection and diagnosis process. One such area of research involves the investigation and application of sophisticated computer algorithms to assist clinicians in detecting and diagnosing breast cancer on medical images (termed generally as "computer-aided diagnosis" or CAD). This study investigated a previously-developed breast ultrasound CAD system with the intent of translating it into a clinically-viable system. While past studies have demonstrated that breast ultrasound CAD may be a beneficial aid during the diagnosis of breast cancer on ultrasound, there are no investigations concerning its potential clinical translation and there are currently no commercially-available implementations of such systems. This study "bridges the gap" between the laboratory-developed system and the steps necessary for clinical implementation. A novel observer study was conducted that mimicked the clinical use of the breast ultrasound CAD system in order to assess the impact it had on the diagnostic performance of the user. Several robustness studies were also performed: the sonographic features used by the system were evaluated and the databases used for calibration and testing were characterized, the effect of the user's input was assessed by evaluating the performance of the system with variations in lesion identification and image selection, and the performance of the system on different patient populations was investigated by evaluating its performance on a database consisting solely of patients with Asian ethnicity. The analyses performed here indicate that the breast ultrasound CAD system under investigation is robust and demonstrates only minor variability when subjected to "real-world" use. All of these results are

    Appendiceal mucocele is a rare cause of acute abdomen. Mucinous appendiceal neoplasms represent 0.2–0.7% of all appendix specimens. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting. A 72-year-old female patient was admitted to the emergency department with a clinical examination indicative of acute abdomen. The patient underwent abdominal computed tomography scan which revealed a cystic lesion in the right iliac fossa measuring 8.3 × 5.2 × 4.1 cm, with calcified walls, and a mean density indicative of high protein content. The patient was taken to the operating room and a right hemicolectomy was performed. The postoperative course was unremarkable. The histopathological examination revealed a low-grade mucinous appendiceal neoplasm with negative regional lymph nodes. Ultrasound and CT are useful in diagnosing appendiceal mucocele and synchronous cancers in the emergency setting. The initial operation should include appendectomy and resection of the appendicular mesenteric fat along with any fluid collection for cytologic examination. During urgent appendectomy it is important to consider every mucocele as malignant in order to avoid iatrogenic perforation causing pseudomyxoma peritonei. Although laparotomy is recommended, the laparoscopic approach is not contraindicated. PMID:27066284

  1. Osteomyelitis in the neonate. Clinical aspects and the role of radiography and scintigraphy in diagnosis and management

    International Nuclear Information System (INIS)

    Based on experience with 22 cases of neonatal osteomyelitis in 10 years, the authors suggest these patients can be divided into two groups depending on severity of disease. Premature infants requiring umbilical catheterization and severely ill full-term infants constitute a high-risk group; signs are more overt, multifocal infection and joint involvement more frequent, and severe skeletal deformities more common. The patients in the low-risk group had much milder disease but also presented more difficulty in diagnosis because of the vagueness of the presenting signs. Radiographic examination is essential for diagnosis and follow-up of osteomyelitis, particularly limb deformities. Bone scans should be reserved for situations in which the clinical and radiographic findings are equivocal

A case of primary gastric Burkitt lymphoma is described in a child presenting as a protein-losing enteropathy, including the direct monitoring of the disease response by sequential endoscopic biopsy and molecular analysis. Case presentation We report a 9-year-old boy who presented with gross oedema, ascites and respiratory distress caused by a protein-losing enteropathy. Initial imaging investigations were non-diagnostic but gastroduodenal endoscopy revealed massive involvement of the gastric mucosa with a primary Burkitt lymphoma. His subsequent clinical progress and disease response were monitored directly by endoscopy and he remains in clinical remission 4 years after initial diagnosis. Conclusions This is the first case report of primary Burkitt lymphoma presenting as a protein-losing enteropathy. The clinical course and progress of the patient were monitored by sequential endoscopic biopsy, histology and molecular analysis by fluorescence in situ hybridisation.

    Full Text Available Background: Clinical criteria (symptoms are not reliable enough to differentiate between different causes of encephalitis. The clinical presentation of herpes simplex virus encephalitis (HSVE is not classically constant and in such a patient, therefore, it is vital to make early diagnosis. Aims: To investigate satisfactory and crucial clinical signs as guide to perform HSV-PCR in a rapid diagnosis of herpes simplex virus encephalitis. Material and Methods: A total of 156 CSF specimens from 70 patients with clinically suspected HSVE or meningoencephalitis were tested. The criteria for cases suspected of HSVE were fever >380C, altered mental status and other critical manifestations. CSF features, irregularity in brain CT scan and MRI findings were also assessed. All the specimens were collected before and after Acyclovir treatment. Polymerase chain reaction was performed using primers, which amplified DNA sequences for both HSV-1 and HSV-2. Statistical Analysis: To analyze data, two-tailed Fisher's exact test and the X2-test with Yates' correction were used as appropriate. The odds ratio was used to express the strength of association between the clinical factors and the PCR results. Results: HSV-DNA was detected in 18% of the specimens, belonging to 25.7% of the patients. Results indicate that the majority of the clinical symptoms are not specific to definitive clinical diagnosis of HSVE, except alteration in the level of consciousness—odds ratio [0.27 (0.07-0.96 (P=0.033]; and lateralization sign—odds ratio [4.7 (0.98-22.6 (P=0.023]. However, laboratory data, including total white blood cell count, especially the number of lymphocytes, and MRI findings could be suggested for HSV-PCR examination. Conclusion: At the first admission, a preliminary finding of at least two important clinical features mentioned above along with the pattern of CSF cell and differential counts could be sufficient to perform HSV-PCR which could ultimately result in a

    Cervical cancer is still one of the most relevant women cancer types, since the 5-year survival rate is of only around 68%. Prevention and early diagnosis are the best strategies to improve cervical cancer prognosis. Conventional diagnosis procedure in Gynecology is mainly based on the macroscopic clinical evaluation, Pap smear cytology, and biopsy, if needed. A portable microscope with dual configuration and its use for diagnosis in Gynecology is investigated. The microscope has interchangeable parts that allow its use for cytopathology smear samples or in situ endoscopic tissue interrogation, both using acriflavine as a nuclei marker. Patients of the Women Ambulatory of the School of Medicine (UNIARA, Araraquara, Brazil) were interrogated during the colposcopy examination. The cervix was initially cleaned using an acetic acid solution, and a 0.05% (wt/vol) acriflavine in saline solution was topically applied at the tissue surface using a cotton swab. Microendoscopy images were taken from clinically normal cervix mucosa and from detected lesions. An image processing is performed to evaluate the cell nuclei morphology and the cytoplasm/nuclei ratio. The Pap smear results and the histology analyses are taken as gold standard for the diagnosis. Preliminary results in 5 patients demonstrated the potential use of our microscope at the clinical setting.

    Introduction Upper airway angioedema is a life-threatening emergency department (ED) presentation with increasing incidence. Angiotensin-converting enzyme inhibitor induced angioedema (AAE) is a non-mast cell mediated etiology of angioedema. Accurate diagnosis by clinical examination can optimize patient management and reduce morbidity from inappropriate treatment with epinephrine. The aim of this study is to describe the incidence of angioedema subtypes and the management of AAE. We evaluate the appropriateness of treatments and highlight preventable iatrogenic morbidity. Methods We conducted a retrospective chart review of consecutive angioedema patients presenting to two tertiary care EDs between July 2007 and March 2012. Results Of 1,702 medical records screened, 527 were included. The cause of angioedema was identified in 48.8% (n=257) of cases. The most common identifiable etiology was AAE (33.1%, n=85), with a 60.0% male predominance. The most common AAE management strategies included diphenhydramine (63.5%, n=54), corticosteroids (50.6%, n=43) and ranitidine (31.8%, n=27). Epinephrine was administered in 21.2% (n=18) of AAE patients, five of whom received repeated doses. Four AAE patients required admission (4.7%) and one required endotracheal intubation. Epinephrine induced morbidity in two patients, causing myocardial ischemia or dysrhythmia shortly after administration. Conclusion AAE is the most common identifiable etiology of angioedema and can be accurately diagnosed by physical examination. It is easily confused with anaphylaxis and mismanaged with antihistamines, corticosteroids and epinephrine. There is little physiologic rationale for epinephrine use in AAE and much risk. Improved clinical differentiation of mast cell and non-mast cell mediated angioedema can optimize patient management. PMID:27330660

    Brugada syndrome is an inherited arrhythmogenic disorder, characterised by coved-type ST-segment elevation in the right precordial leads, and is associated with increased risk of sudden death. It is genetically and clinically heterogeneous, presenting typically in the fourth or fifth decade of life. The prevalence of Brugada syndrome in the paediatric population is low compared with the adult population. Interestingly, over the last several years, there has been growing evidence in the literature of onset of the disease during childhood. Most of the paediatric cases reported in the literature consist of asymptomatic Brugada syndrome; however, some patients manifest the disease at different regions of the cardiac conduction system at a young age. Early expression of the disease can be affected by multiple factors, including genetic substrate, hormonal changes, and still unknown environmental exposures. The initial manifestation of Brugada syndrome in children can include sinus node dysfunction and atrial arrhythmias. Brugada syndrome can also manifest as ventricular arrhythmias leading to sudden death at an early age. In symptomatic children, performance of the ajmaline test by an experienced team can be safely used as a diagnostic tool to unmask latent Brugada syndrome. Defining indications for an implantable cardioverter defibrillator in children with the diagnosis of Brugada syndrome remains challenging. Given the rarity of the syndrome in children, most paediatric cardiologists will only rarely see a young patient with Brugada syndrome and there is still no universal consensus regarding the optimal management approach. Care should be individualised according to the specific clinical presentation, taking into account the family history, genetic data, and the family's specific preferences. PMID:27151277

Epinephrine induced morbidity in two patients, causing myocardial ischemia or dysrhythmia shortly after administration. Conclusion: AAE is the most common identifiable etiology of angioedema and can be accurately diagnosed by physical examination. It is easily confused with anaphylaxis and mismanaged with antihistamines, corticosteroids and epinephrine. There is little physiologic rationale for epinephrine use in AAE and much risk. Improved clinical differentiation of mast cell and non-mast cell mediated angioedema can optimize patient management.

    Full Text Available Abstract Background Although Venezuela has a National Human Immunodeficiency Virus (HIV Program offering free diagnosis and treatment, 41% of patients present for diagnosis at a later disease-stage, indicating that access to care may still be limited. Our study aimed to identify factors influencing delay in presenting for HIV-diagnosis using a case-case comparison. A cross-sectional survey was performed at the Regional HIV Reference Centre (CAI, Carabobo Region, Venezuela. Between May 2005 and October 2006 225 patients diagnosed with HIV at CAI were included and demographic, behavioural and medical characteristics collected from medical files. Socio-economic and behavioural factors were obtained from 129 eligible subjects through interviews. "Late presentation" at diagnosis was defined as patients classified with disease-stage B or C according to the 1993 Centers for Disease Control and Prevention (Atlanta, USA classification, and "early presentation" defined as diagnosis in disease-stage A. Results Of 225 subjects, 91 (40% were defined as late presenters. A similar proportion (51/129 was obtained in the interviewed sub-sample. Older age (>30 years, male heterosexuality, lower socio-economic status, perceiving ones partner to be faithful and living ≥ 25 km from the CAI were positively associated with late diagnosis in a multivariate model. Females were less likely to present late than heterosexual males (odds ratio = 0.23, P = 0.06. The main barriers to HIV testing were low knowledge of HIV/AIDS, lack of awareness of the free HIV program, lack of perceived risk of HIV-infection, fear for HIV-related stigma, fear for lack of confidentiality at testing site and logistic barriers. Conclusion Despite the free Venezuelan HIV Program, poverty and barriers related to lack of knowledge and awareness of both HIV and the Program itself were important determinants in late presentation at HIV diagnosis. This study also indicates that women; heterosexual

    Vocal cord dysfunction (VCD) is a syndrome characterized by the intermittent, abnormal paradoxical adduction of the true vocal cords during respiration resulting in variable upper airway obstruction. It is also commonly referred to as paradoxical vocal fold motion disorder. Patients with VCD usually present with intermittent shortness of breath of varying intensity, wheezing, stridor, choking, throat tightness, voice changes, or cough, and these symptoms often resolve quickly after relaxation or cessation of activity. Since first described as a distinct clinical entity in 1983, VCD remains underrecognized and the underlying cause(s) is not fully understood. Several studies suggest psychogenic or laryngeal hyperresponsiveness as possible underlying causes. Although VCD may have many causes, it can be a unique problem, especially in athletes because it often mimics and can be easily mistaken for exercise-induced bronchospasm, which may result in unnecessary medical treatment and delay in diagnosis. A detailed history, physical examination, and pulmonary function tests with flow-volume loops are important for excluding other diagnoses; however, the gold standard method for diagnosing VCD is by observation of the vocal cords with flexible laryngoscopy. The mainstay of treatment includes behavioral management guided by a speech-language pathologist, but optimal therapy often requires a multidisciplinary team involving a variety of specialties, including certified athletic training, pulmonology, otolaryngology, speech-language pathology, gastroenterology, allergy and immunology, and psychology, as appropriate. We reviewed the medical literature for VCD specifically in athletes, and this article discusses in detail the definition, epidemiology, possible pathophysiology, diagnosis, and treatment options.

  13. Survey for primary tumor site in patients with initial clinical presentation of bone metastasis

    International Nuclear Information System (INIS)

    Among the patients who were examined with bone scintigraphy between April 1985 and March 1991, there were 27 patients whose initial clinical manifestation was bone metastasis and who were surveyed for the primary tumor site. The primary tumor site could be identified in 20 patients (74%), consisting of 9 patients with lung cancer, 3 with prostate cancer, 3 with hepatoma, 2 with renal cancer, and one each with thyroid cancer, adrenal cancer, and pleural malignant mesothelioma. In 17 of the 20 patients, the primary site had been detected within two months after presentation. Examinations which were helpful in identifying the primary site included chest radiography, sputum cytology, abdominal sonography, serum prostatic acid phosphatase level and pathologic examination of biopsy specimens. 99mTc-pyridoxylenemethyl tryptophan (99mTc-PMT) scintigraphy was useful in the diagnosis of the hepatoma when accumulation was observed at the metastatic sites. In 2 patients, lung cancer had been recognized using follow-up chest, radiography 3 and 6 months after presentation, respectively. One patient was diagnosed at autopsy as having adrenal cancer. In 7 patients the primary site remains unknown. Histology examination of the biopsy specimen performed in 6 of these patients revealed 4 to be adenocarcinoma and 2 undifferentiated carcinoma. The average survival period of the 17 patients who died was 9.5 months. Four patients are alive, and the outcome in the remaining 6 could not be determined. (author)

    @@ Nonvalvular atrial fibrillation (NVAF) is the most common sustained cardiac arrhythmia in clinical practice, which if untreated results in a doubling of cardiovascular morbidity and mortality. AF is an independent predictor of stroke, with an annual risk 5 to 6 times higher than patients in sinus rhythm.1 During recent years, several randomised clinical trials conducted by investigators around the world involving 13 843 participants with NVAF have demonstrated convincingly the value of warfarin therapies for stroke prevention in high risk patients.2-8 However, the dose response of warfarin is complex and its activity is easily altered by concurrent medications, food interactions, alcohol and illnesses. Adherence to medical advice and routine monitoring of the international normalized ratio (INR) is important, because low anticoagulant intensity predisposes the patients to thromboembolic complications and high intensity to haemorrhage. Studies suggested that anticoagulant clinics could improve the quality of anticoagulation control,9 and anticoagulant clinics are common in western countries. However, in China, most AF patients taking warfarin usually attend the outpatient clinic of cardiology, while the quality of anticoagulation control is never investigated. We therefore assessed anticoagulation control in the outpatient clinic of cardiology, and the quality of anticoagulation control since the establishment of anticoagulant clinics.

    Incorrect or improper diagnostic tests uses have important implications for health outcomes and costs. Clinical Decision Support Systems purports to optimize the use of diagnostic tests in clinical practice. The computerized medical reasoning should not only focus on existing medical knowledge but also on physician's previous experiences and new knowledge. Such medical knowledge is vague and defines uncertain relationships between facts and diagnosis, in this paper, Case Based Fuzzy Cognitive Maps (CBFCM) are proposed as an evolution of Fuzzy Cognitive Maps. They allow more complete representation of knowledge since case-based fuzzy rules are introduced to improve diagnosis decision. We have developed a framework for interacting with patient's data and formalizing knowledge from Guidelines in the domain of Urinary Tract Infection. The conducted study allowed us to test cognitive approaches for implementing Guidelines with Semantic Web tools. The advantage of this approach is to enable the sharing and reuse of knowledge from Guidelines, physicians experiences and simplify maintenance. PMID:22874199

    International Nuclear Information System (INIS)

    Objective: To evaluate the display ability and the clinical application of CT virtual endoscopy (CTVE) in the diagnosis of aortic disease. Methods: In this group, 147 cases with clinically suspected aortic disease (113 males, 34 females) underwent CTVE and 58 cases had DSA for comparison. 37 cases were confirmed by operation. Results: (1) In the 147 cases, 139 cases showed successful CTVE images. (2) CTVE images could clearly show the inner wall and inner structures of the vessels, the true and false luminal of aortic dissections, and the lesion of false aneurysm. Conclusion: CTVE could provide more information of the vessel by displaying the inner wall and allowing users to map the vessels in a display. It is helpful in correct diagnosis and guiding surgery

  20. Clinical Significance of Detection of Serum TBA and ALP in Diagnosis of Intrahepatic Cholestasis of Pregnancy

    International Nuclear Information System (INIS)

    To investigate the clinical value of serum total bile acid (TBA) and alkaline phosphatase (ALP) in diagnosis of intahrpatic cholestasis of pregnancy (ICP), the serum levels of TBA, ALP and cholyglycine (CG) in 47 cases with intahrpatic cholestasis of pregnancy and 60 normal pregnant women were tested by biochemistry analysis and radioimmunoassay. The results showed that the serum levels of TBA and ALP in patients with intahrpatic cholestasis of pregnancy were significantly higher than that of normal pregnancy women. There was a positively correlation between TBA and ALP with CG. The combined determination of serum TBA and ALP could be useful in the diagnosis of intahrpatic cholestasis of pregnancy. Automatic biochemistry analysis of TBA and ALP is more simple and rapid than CG detected by radioimmunoassay,and it is suitable for clinical laboratory application. (authors)

  1. Targeted NGS meets expert clinical characterization: Efficient diagnosis of spastic paraplegia type 11

    2015-06-01

    Full Text Available Next generation sequencing (NGS is transforming the diagnostic approach for neurological disorders, since it allows simultaneous analysis of hundreds of genes, even based on just a broad, syndromic patient categorization. However, such an approach bears a high risk of incidental and uncertain genetic findings. We report a patient with spastic paraplegia whose comprehensive neurological and imaging examination raised a high clinical suspicion of SPG11. Thus, although our NGS pipeline for this group of disorders includes gene panel and exome sequencing, in this sample only the spatacsin gene region was captured and subsequently searched for mutations. Two probably pathogenic variants were quickly and clearly identified, confirming the diagnosis of SPG11. This case illustrates how combination of expert clinical characterization with highly oriented NGS protocols leads to a fast, cost-efficient diagnosis, minimizing the risk of findings with unclear significance.

  2. Positron Emission Tomography (PET) and its application in clinical diagnosis and functional brain organization studies

    International Nuclear Information System (INIS)

    Recent advances in positron emission tomography (PET) and other brain-imaging techniques have made it possible to visualize the working brain while the human subject is thinking, speaking or planning an action. PET provides researches with an opportunity to infer the neuroanatomy of a given function. Subjects either inhale or are injected with a radioactive material that binds to a physiologically active compound in the body. This serves as a tracer of blood flow and metabolic processes that reflect the activation of a given structure by emitting gamma rays which may be detected through a tomograph. PET research has produced findings that extend our knowledge on several important issues such as cerebral representation of language, perception, attention or memory. It has also proven to be an important source of information for clinical diagnosis of various neurological and psychiatric diseases. The present article provides a short review of main achievements in those fields. However, functional brain imaging is not exempt from methodological and theoretical difficulties. The main limitations of the method have been outlined. (author)

  3. Acquired hepatocerebral degeneration and hepatic encephalopathy: correlations and variety of clinical presentations in overt and subclinical liver disease

    2011-06-01

    Full Text Available Acquired hepatocerebral degeneration (AHD and hepatolenticular degeneration can have similar clinical presentations, but when a chronic liver disease and atypical motor findings coexist, the distinction between AHD and hepatic encephalopathy (HE can be even more complicated. We describe three cases of AHD (two having HE with different neuroimaging findings, distinct hepatic diseases and similar motor presentations, all presenting chronic arterial hypertension and weight loss before the disease manifestations. The diagnosis and physiopathology are commented upon and compared with previous reports. In conclusion, there are many correlations among HE, hepatolenticular degeneration and AHD, but the overlapping of AHD and HE could be more common depending on the clinical knowledge and diagnostic criteria adopted for each condition. Since AHD is not considered a priority that affects the liver transplant list, the prognosis in AHD patients remains poor, and flow interruption in portosystemic shunts must always be taken into account.

    Full Text Available Abstract Background Several enzyme-linked immunosorbent assay (ELISA-kits are commercially available for the rapid diagnosis of dengue infection, and have demonstrated good sensitivity and specificity in paired serum samples. In practice, however, often only one blood sample is available from febrile travellers returning from dengue endemic areas. Methods To evaluate the diagnostic value of positive dengue antibody-titres performed by a standard ELISA (PanBio IgM- and IgG-ELISA in single serum samples (regarded as "probable infection", 127 positive samples were further analyzed using envelope/membrane IgM-, and nonstructural protein 1 IgM- and IgG-ELISAs, immunofluorescence assays, and real-time reverse transcription polymerase chain reaction assays (RT-PCR. A combination of the test-results served as the diagnostic "gold standard". A total of 1,035 febrile travellers returning from dengue-endemic countries with negative dengue-serology and RT-PCR served as controls to compare clinical and haematological features. Results Overall, only 64 (positive predictive value = 50% of the probable cases were confirmed by additional analysis and 54 (42.5% were confirmed to be "false-positive". Rash was the only clinical feature significantly associated with confirmed dengue fever. The combination of thrombocytopenia and leucopenia was present in 40.4% of confirmed and in 6.1% of false-positive cases. Thus, the positive predictive value for the combination of positive PanBio-ELISA plus the two haematological features was 90.5%. Conclusion The examination of paired serum samples is considered the most reliable serodiagnostic procedure for dengue. However, if only one blood sample is available, a single positive ELISA-result carries a high rate of false-positivity and should be confirmed using a second and more specific diagnostic technique. In the absence of further testing, platelet and white blood cell counts are helpful for the correct interpretation.

  5. Clinical diagnosis of polycystic ovarian syndrome and response to metformin therapy

    International Nuclear Information System (INIS)

    To determine the accuracy of diagnosing polycystic ovarian syndrome (PCOS) predominantly on clinical features and the response to metformin therapy. Women fulfilling the inclusion criteria (oligo/hypomenorrhea, infertility, weight gain, hyperandrogenism) were enrolled. Ultrasound pelvis was obtained in all women. Presence of eight or more multiple follicles in both or one ovary without presence of mature follicle was the cutoff number for positive ultrasound. Thyroid stimulating hormone levels were performed in all patients, and patients with abnormal levels were excluded from the study. Metformin was adjusted to 500 mg thrice daily. Six months later patients were again evaluated for response to metformin therapy and those who failed to conceive were given clomiphene citrate along with metformin. Fertility was re-evaluated at the end of one year. At the start of the study, 81% women had menstrual irregularity and 84% had infertility. Hirsutism was seen in 72% while history of weight gain was present in 62% of patients. Ultrasound evidence of polycystic ovaries was seen in 93% of women. After 6 months of metformin therapy, 80% patients had achieved correction in their menstrual irregularity. After 6 months on metformin alone, 51% patients conceived while an additional 20% conceived on both metformin and clomiphene citrate during next 6 months. Overall fertility rate was 71% at the end of one year. There was statistically significant change in pre-treatment and post-treatment BMI. Combination of three or more of the clinical features (irregular cycles, history of weight gain, infertility and hirsutism) provide an appropriate basis for the diagnosis of PCOS. Metformin alone was an effective treatment for PCOS in this series. (author)

  7. Tuberculous meningits in adults in Turkey: Epidemiology, diagnosis, clinic and laboratory

    International Nuclear Information System (INIS)

    A retrospective study was performed to assess the epidemiology, diagnosis, clinic, and laboratory of the patients with tuberculous meningitis (TBM) in a multicentral study. The medical records of adult cases with TBM treated at 12 university hospitals throughout Turkey, between 1985 and 1998 were reviewed using a standardized protocol. The diagnosis of TMB was established with the clinical and laboratory findings and/or microbiological confirmation in cerebrospinal fluid (CSF). The non-microbiologically confirmed cases were diagnosed with five diagnostic sub-criteria which CSF findings, radiological findings, extra-neural tuberculosis, epidemiological findings and response to antituberculous therapy. A total of 469 patients were included in this study. Majority of the patients were from Southeast Anatolia (164 patients, 35.0%) and (108 patients, 23.0%) from East Anatolia regions. There was a close contact with a tuberculous patient in 88 of 341 patients (25.8%) and with a tuberculous family member in 53 of 288 patients (18.4%). BCG scar was positive in 161 of 392 patients (41.1%). Tuberculin skin test was done in 233 patients and was found to be negative in 75. Totally 115 patients died (24.5%) of whom 23 died in 24 hour after admittance. The diagnosis was confirmed with clinical findings and CSF culture and/or Ziehl-Nelson staining in 88 patients (18.8%). Besides clinical criteria, there were three or more diagnostic sub-criteria in 252 cases (53.7%), two diagnostic sub-criteria in 99 cases (21.1%), and any diagnostic sub-criteria in 30 patients (6.4%). Since TBM is a very critical disease, early diagnosis and treatment may reduce fatal outcome and morbidity

  10. Recent advances of ventilation-perfusion scintigraphy in clinical diagnosis and interventional treatment of pulmonary embolism

    International Nuclear Information System (INIS)

    Ventilation-perfusion scintigraphy can reflect the pulmonary function of ventilation and perfusion, then, indirectly assess the distribution of embolism. This technique is especially valuable in evaluating hemodynamic stability in patients with suspected pulmonary embolism. Ventilation-perfusion scintigraphy is superior to other imaging means in clinical practice as it is non-invasive and carries high specificity in detecting sub-segmental embolism. Furthermore, the advantages of interventional therapy are of significant clinical value in treating pulmonary embolism. This paper aims to make a comprehensive review for the ventilation-perfusion scintigraphy diagnosis, as well as the interventional treatment, of pulmonary embolism. (authors)

    2016-01-01

    Purpose The genetics underlying inherited color vision deficiencies is well understood: causative mutations change the copy number or sequence of the long (L), middle (M), or short (S) wavelength sensitive cone opsin genes. This study evaluated the potential of opsin gene analyses for use in clinical diagnosis of color vision defects. Methods We tested 1872 human subjects using direct sequencing of opsin genes and a novel genetic assay that characterizes single nucleotide polymorphisms (SNPs) using the MassArray system. Of the subjects, 1074 also were given standard psychophysical color vision tests for a direct comparison with current clinical methods. Results Protan and deutan deficiencies were classified correctly in all subjects identified by MassArray as having red–green defects. Estimates of defect severity based on SNPs that control photopigment spectral tuning correlated with estimates derived from Nagel anomaloscopy. Conclusions The MassArray assay provides genetic information that can be useful in the diagnosis of inherited color vision deficiency including presence versus absence, type, and severity, and it provides information to patients about the underlying pathobiology of their disease. Translational Relevance The MassArray assay provides a method that directly analyzes the molecular substrates of color vision that could be used in combination with, or as an alternative to current clinical diagnosis of color defects.

    Myeloid sarcoma results from the extramedullary homing and proliferation of immature myeloid precursors. We present the timeline, events and diagnostic pitfalls related to a 66 year-old male patient's case, admitted to the Hematology Clinic for pancytopenia, fever, weight loss and fatigue. The severe cytopenia and the few blasts observed in his blood smear indicated a bone marrow biopsy. The bone marrow showed hypercellularity and multilineage dysplasia with the presence of 15% myeloblasts. After the biopsy, he promptly developed paraplegia and nuclear magnetic resonance revealed an epidural tumour which was then resected.In the epidural tumour mass blast-like, round cells were observed with a complex immunophenotype, characterized by myeloperoxidase, CD117, CD15, CD99, leucocyte common antigen positivity and a high Ki-67 proliferation index. Considering the main differential diagnostic issues, the final diagnosis was stated as myelodysplastic syndrome-associated myeloid sarcoma. The prognosis was unfavourable, the bone marrow was quickly invaded by proliferating blast cells, and despite chemotherapy attempts, the patient died. PMID:27019694

    We studied the frequency, clinical presentation, and outcomes of deep vein thrombosis (DVT). Serial Doppler ultrasonography was performed between 2008 and 2013 for 6420 patients with suspected DVT. Diagnosis was confirmed in 662 (10.3%) participants (mean age: 50 ± 17 years; 51% females). Obesity, diabetes mellitus, and malignancy were reported in 47%, 28%, and 16%, respectively. Abnormal protein C, protein S, factor V Leiden, or antithrombin III were found in 9%, 7%, 3.8%, and 4%, respectively. Left, right, and both legs were involved in 55%, 37%, and 8%, respectively. Common femoral, popliteal, and posterior tibial veins were affected in 48.5%, 72%, and 71%, respectively. Postthrombotic syndrome, pulmonary embolism, and death were reported in 50%, 12.2%, and 15% of cases, respectively. Kaplan-Meier survival curves and Cox regression analysis showed that gender had no impact on mortality during follow-up; however, age (>50 years) was associated with greater risk of death (hazard ratio: 6.54; 95% confidence interval: 3.2-13.3). These findings will improve our understanding of the various risk factors and help develop institutional guidelines for the management of patients with DVT. PMID:26345414

    Full Text Available Fungal urinary tract infections are an increasing problem in hospitalized patients. Funguria may be a result of contamination of the urine specimen, colonization of the urinary tract, or may be indicative of true invasive infection. In this study, we report the risk factors, clinical features, treatments and outcome in a group of 68 hospitalized patients (adults and children with fungal isolates recovered from 103 urinary samples. Underlying medical conditions were present in most patients. In the pediatric group, urinary tract abnormalities (86% and prematurity (19% accounted for the majority of the cases. Diabetes mellitus (28%, nephrolithiasis, and benign prostatic hyperplasia were the most common diseases in adults. Indwelling urethral catheters were noted in 38% of the pediatric patients and in 43% of adults during hospitalization. Candida albicans strains were responsible for 97% and 75% of positive cultures in children and adults, respectively. Symptoms such as fever, dysuria, frequency and flank pain were generally absent in both groups. Fluconazole was the most frequent antifungal utilized (61% in children and ketoconazole in the adult group (42%. Removing the urinary catheter was attempted in 6 pediatric patients (29% and in only 8 adults (17%. One patient (4% in the pediatric group died compared to 10 in the adult group (21%, p=0.04. Successful diagnosis and treatment of funguria depends on a clear understanding of the risk factors and awareness of fungal epidemiology.

    Abstract Background: The first cases of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) were described>15 years ago. Since that time, the literature has been divided between studies that successfully demonstrate an etiologic relationship between Group A streptococcal (GAS) infections and childhood-onset obsessive-compulsive disorder (OCD), and those that fail to find an association. One possible explanation for the conflicting reports is that the diagnostic criteria proposed for PANDAS are not specific enough to describe a unique and homogeneous cohort of patients. To evaluate the validity of the PANDAS criteria, we compared clinical characteristics of PANDAS patients identified in two community practices with a sample of children meeting full research criteria for PANDAS. Methods: A systematic review of clinical records was used to identify the presence or absence of selected symptoms in children evaluated for PANDAS by physicians in Hinsdale, Illinois (n=52) and Bethesda, Maryland (n=40). Results were compared against data from participants in National Institute of Mental Health (NIMH) research investigations of PANDAS (n=48). Results: As described in the original PANDAS cohort, males outnumbered females (95:45) by ∼ 2:1, and symptoms began in early childhood (7.3±2.7 years). Clinical presentations were remarkably similar across sites, with all children reporting acute onset of OCD symptoms and multiple comorbidities, including separation anxiety (86–92%), school issues (75–81%), sleep disruptions (71%), tics (60–65%), urinary symptoms (42–81%), and others. Twenty of the community cases (22%) failed to meet PANDAS criteria because of an absence of documentation of GAS infections. Conclusions: The diagnostic criteria for PANDAS can be used by clinicians to accurately identify patients with common clinical features and shared etiology of symptoms. Although difficulties in documenting an association
