    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.

    Full Text Available Mucocutaneous Leishmaniasis (ML can lead to serious sequela; however, early diagnosis can prevent complications. AIM: To evaluate clinical markers for the early diagnosis of ML. MATERIALS AND METHODS: A series study of 21 cases of ML, which were evaluated through clinical interview, nasal endoscopy, biopsy and the Montenegro test. RESULTS: A skin scar and previous diagnosis of cutaneous leishmaniasis (CL were reported in 8(38% patients, and 13(62% of them denied having had previous CL and had no scar. Nasal/oral symptom onset until the ML diagnosis varied from 5 months to 20 years, mean value of 6 years. In the Montenegro test, the average size of the papule was 14.5 mm, which did not correlate with disease duration (p=0.87. The nose was the most often involved site and the extension of the injured mucosa did not correlate with disease duration. The parasite was found in 2 (9.52% biopsy specimens. CONCLUSIONS: ML diagnosis was late. Finding the parasite in the mucosa, cutaneous scar and/or previous diagnosis of CL were not clinical markers for ML. ML diagnosis must be based on the Montenegro test, chronic nasal and/or oral discharge and histological findings ruling out other granulomatous diseases.A leishmaniose cutâneo-mucosa (LM pode deixar sequelas graves.

    To test the recommendation from the Canadian guidelines for sexually transmitted diseases (STDs) that mucopurulent endocervical discharge and 10 or more polymorphonuclear leukocytes (PMNs) per high-power field of a Gram-stained endocervical smear or, when Gram staining is not possible, the presence of endocervical discharge and one of edema, erythema or induced mucosal bleeding of the cervix can be considered diagnostic for chlamydial cervicitis. A total of 596 consecutive women attending 2 family planning clinics for routine care underwent vaginal speculum examination and were tested for Chlamydia trachomatis and Neisseria gonorrhoeae. PMN counts from Gram-stained endocervical smears and the presence or absence of putative indicators of chlamydial infection were recorded. The prevalence of chlamydial cervicitis was 6.2% (37/596), and no women tested positive for N. gonorrhoeae. Presumptive diagnosis of chlamydial cervicitis based on the guidelines criteria of mucopurulent endocervical discharge and 10 or more PMN per high-power microscopic field had a sensitivity and specificity of 18.9% and 97.0% respectively, a positive predictive value of 29.2% and a positive likelihood ratio (LR) of 6.2 (p = 0.003). Presumptive diagnosis based on endocervical discharge with edema, erythema or induced mucosal bleeding of the cervix had a sensitivity and specificity of 43.2% and 80.0% respectively, a positive predictive value of 12.5% and a positive LR of 2.2 (p = 0.002). In the presence of bacterial vaginosis or vaginitis, the LR for the criteria of mucopurulent endocervical discharge and 10 or more PMN per high-power field was 5.4 (p = 0.04), whereas the LR was 4.3 (p = 0.10) if bacterial vaginosis and vaginitis were absent. In this setting, the practice of making a presumptive diagnosis of chlamydial cervicitis on the basis of the criteria given in the Canadian STD guidelines was not supported.

    In Denmark, patients referred from the general practitioner (GP) to the emergency department (ED) can be referred with either specific symptoms or with a presumptive diagnosis. The aim of the present study was to evaluate the diagnostic accuracy for various presumptive diagnoses made by the GP in a population acutely referred to an ED. This was a retrospective cohort study of all registered acute referrals for admission to Kolding ED in 2010. Eight presumptive diagnoses were selected for further studies: meningitis, acute coronary syndrome (ACS), pulmonary embolism, pneumonia, pancreatitis, deep venous thrombosis (DVT), pyelonephritis and intestinal obstruction. The presumptive diagnoses were compared with the final diagnosis on discharge. Sensitivity, specificity, predictive values and likelihood ratios were calculated. A total of 8,841 patients were enrolled. The highest and lowest sensitivities were seen for DVT (90%) and meningitis (36%), respectively; and the highest and lowest values for specificity were observed for meningitis (99%) and ACS (30%), respectively. The positive predictive value had a wide range with the lowest value for ACS (9%) and the highest for pneumonia (59%). For pyelonephritis, meningitis and pancreatitis, the likelihood ratio of a positive test was above 10. The likelihood ratio of a negative test was above 0.1 for all diagnoses. Patients referred with the presumptive diagnoses pyelonephritis, meningitis and pancreatitis had a high likelihood of having the disease in question. It is important not to discard any of the included presumptive diagnoses even if the GPs fail to suggest them on admission. none. none.

    1988-01-01

    A case has been presented of a 72-year-old man on whom an excretory urogram showed the incidental findings of two soft tissue masses in the abdomen containing considerable deposits of calcium. The history was interesting in that the patient was classic hemophiliac with Factor VIII level less than 1%, who first developed symptoms and signs of multiple hemarthroses affecting the knees, ankles, elbows, and shoulders at the age of nine years. Secondary hemophilic arthropathy followed, particularly advanced in the right elbow. Total knee replacements were performed within the last 10 years. A mass within the muscles of the right chest wall, superficial to the ribs, was surgically removed. The abdominal masses in this case were studied with CT and showed considerable calcification with a fibrous wall. Surgical removal of pseudotumors is usually undertaken following diagnosis because the natural history includes continuous enlargement and destruction of the adjacent tissues. Because of the age of the patient and the significant cardiac history, it was considered inappropriate to undertake surgery for the masses in the abdomen which were considered presumptively to be pseudotumors. The clinical, radiological, and pathological aspects of pseudotumor of hemophilia were reviewed. In this case, besides the masses in the abdomen, hemophilic arthropathy of an elbow was illustrated and a soft tissue mass in the right chest wall was demonstrated radiologically and the pathological specimen shown after surgical excision.

    OBJECTIVE To compare clinical signs and outcomes between dogs with presumptive ischemic myelopathy and dogs with presumptive acute noncompressive nucleus pulposus extrusion (ANNPE). DESIGN Retrospective study. ANIMALS 51 dogs with ischemic myelopathy and 42 dogs with ANNPE examined at 1 referral hospital. PROCEDURES Medical records and MRI sequences were reviewed for dogs with a presumptive antemortem diagnosis of ischemic myelopathy or ANNPE. Information regarding signalment, clinical signs at initial examination, and short-term outcome was retrospectively retrieved from patient records. Long-term outcome information was obtained by telephone communication with referring or primary-care veterinarians and owners. RESULTS Compared with the hospital population, English Staffordshire Bull Terriers and Border Collies were overrepresented in the ischemic myelopathy and ANNPE groups, respectively. Dogs with ANNPE were significantly older at disease onset and were more likely to have a history of vocalization at onset of clinical signs, have spinal hyperesthesia during initial examination, have a lesion at C1-C5 spinal cord segments, and be ambulatory at hospital discharge, compared with dogs with ischemic myelopathy. Dogs with ischemic myelopathy were more likely to have a lesion at L4-S3 spinal cord segments and have long-term fecal incontinence, compared with dogs with ANNPE. However, long-term quality of life and outcome did not differ between dogs with ischemic myelopathy and dogs with ANNPE. CONCLUSIONS AND CLINICAL RELEVANCE Results revealed differences in clinical signs at initial examination between dogs with ischemic myelopathy and dogs with ANNPE that may aid clinicians in differentiating the 2 conditions.

    Pre-diagnosis attrition needs to be addressed urgently if we are to make progress in improving MDR-TB case detection and achieve universal access to MDR-TB care. We report the pre-diagnosis attrition, along with factors associated, and turnaround times related to the diagnostic pathway among patient with presumptive MDR-TB in Bhopal district, central India (2014). Study was conducted under the Revised National Tuberculosis Control Programme setting. It was a retrospective cohort study involving record review of all registered TB cases in Bhopal district that met the presumptive MDR-TB criteria (eligible for DST) in 2014. In quarter 1, Line Probe Assay (LPA) was used if sample was smear/culture positive. Quarter 2 onwards, LPA and Cartridge-based Nucleic Acid Amplification Test (CbNAAT) was used for smear positive and smear negative samples respectively. Pre-diagnosis attrition was defined as failure to undergo DST among patients with presumptive MDR-TB (as defined by the programme). Of 770 patients eligible for DST, 311 underwent DST and 20 patients were diagnosed as having MDR-TB. Pre-diagnosis attrition was 60% (459/770). Among those with pre-diagnosis attrition, 91% (417/459) were not identified as 'presumptive MDR-TB' by the programme. TAT [median (IQR)] to undergo DST after eligibility was 4 (0, 10) days. Attrition was more than 40% across all subgroups. Age more than 64 years; those from a medical college; those eligible in quarter 1; patients with presumptive criteria 'previously treated - recurrent TB', 'treatment after loss-to-follow-up' and 'previously treated-others'; and patients with extra-pulmonary TB were independent risk factors for not undergoing DST. High pre-diagnosis attrition was contributed by failure to identify and refer patients. Attrition reduced modestly with time and one factor that might have contributed to this was introduction of CbNAAT in quarter 2 of 2014. General health system strengthening which includes improvement in

    A study was conducted in 1997 to compare the accuracy of presumptive diagnosis of malaria in children aged 1-9 years performed by caretakers of the children to that of health centre staff in 2 ecological zones in southern Ghana. Similar symptoms were reported in the children at home and at the health centre. In the home setting, symptoms were reported the same day that they occurred, 77.6% of the children with a report of fever were febrile (axillary temperature > or = 37.5 degrees C) and 64.7% of the reports of malaria were parasitologically confirmed. In the health centre, the median duration of symptoms before a child was seen was 3 days (range 1-14 days), 58.5% of the children with a report of fever were febrile and 62.6% of the clinically diagnosed cases were parasitologically confirmed. In the 2 settings almost all the infections were due to Plasmodium falciparum. Parasite density was 3 times higher in the health centre cases compared to the home-diagnosed cases. Early and appropriate treatment of malaria detected in children by caretakers may prevent complications that arise as a result of persistence of symptoms and attainment of high parasitaemic levels.

    Full Text Available Diagnosis of pulmonary tuberculosis (PTB in children is challenging due to difficulties in obtaining good quality sputum specimens as well as the paucibacillary nature of disease. Globally a large proportion of pediatric tuberculosis (TB cases are diagnosed based only on clinical findings. Xpert MTB/RIF, a highly sensitive and specific rapid tool, offers a promising solution in addressing these challenges. This study presents the results from pediatric groups taking part in a large demonstration study wherein Xpert MTB/RIF testing replaced smear microscopy for all presumptive PTB cases in public health facilities across India.The study covered a population of 8.8 million across 18 programmatic sub-district level tuberculosis units (TU, with one Xpert MTB/RIF platform established at each study TU. Pediatric presumptive PTB cases (both TB and Drug Resistant TB (DR-TB accessing any public health facilities in study area were prospectively enrolled and tested on Xpert MTB/RIF following a standardized diagnostic algorithm.4,600 pediatric presumptive pulmonary TB cases were enrolled. 590 (12.8%, CI 11.8-13.8 pediatric PTB were diagnosed. Overall 10.4% (CI 9.5-11.2 of presumptive PTB cases had positive results by Xpert MTB/RIF, compared with 4.8% (CI 4.2-5.4 who had smear-positive results. Upfront Xpert MTB/RIF testing of presumptive PTB and presumptive DR-TB cases resulted in diagnosis of 79 and 12 rifampicin resistance cases, respectively. Positive predictive value (PPV for rifampicin resistance detection was high (98%, CI 90.1-99.9, with no statistically significant variation with respect to past history of treatment.Upfront access to Xpert MTB/RIF testing in pediatric presumptive PTB cases was associated with a two-fold increase in bacteriologically-confirmed PTB, and increased detection of rifampicin-resistant TB cases under routine operational conditions across India. These results suggest that routine Xpert MTB/RIF testing is a promising

    To report the clinical presentation and oncologic outcomes of a series of patients who presented with an abdominal or pelvic mass and were diagnosed with a gastrointestinal stromal tumor (GIST). Data were obtained on all patients who presented with an abdominal or pelvic mass between September 2007 and June 2010 and who were ultimately diagnosed with a GIST. The patients' medical records were reviewed. A literature review was also conducted. Six patients were identified who met the inclusion criteria. All six patients had a tumor in the intestinal tract arising from the small bowel. The mean tumor size was 12 cm (range, 6 to 22 cm). A complete resection was achieved in five of the six patients. There were no intraoperative complications; one patient had a postoperative complication. Two patients were treated with imatinib after surgery. The mean follow-up time was 32 months (range, 0.3 to 40 months). At the last follow-up, five of the six patients were without any evidence of disease. One patient died of an unrelated hepatic encephalopathy. The incidence in our institution is 3%. GISTs are uncommon; however, they should be considered in the differential diagnosis of patients presenting with an abdominal or pelvic mass.

  15. Immunodiagnostic confirmation of hydatid disease in patients with a presumptive diagnosis of injection

    Varela-Diaz, V.M.; Coltorti, E.A.

    Information obtained from the routine application of hydatid immunodiagnostic techniques in different clinical situations over a seven-year period is presented. The immunoelectrophoresis test was used and was replaced by the arc 5 double diffusion (DD5) test. Examination of sera from 1.888 patients with signs and/or symptoms comparatible with hydatid disease revealed that the presurgical confirmation of Echinococcus granulosus infection is only obtained by detection of anti-antigen 5 antibodies. In all patients whose preoperative serum showed three or more uncharacteristic bands in the absence of anti-antigen 5 antibodies, hydatid cysts were found surgically. DD5 testing of a fluid sample collected by puncture estabilished its hydatid etiology. Post-operative monitoring of hydatidosis patients demonstrated that persistence of DD5-positivity two years after surgery established the presence of ther cysts.

    Lactobacillus spp. are part of the normal human flora and are generally assumed to be nonpathogenic. We determined the genotypic identification of >100 Lactobacillus isolates from clinical specimens in the context of presumed pathogenic potential (e.g., recovered as the single/predominant isolate from a sterile site or at ≥105 CFU/ml from urine). This study assessed the clinical significance and the frequency of occurrence of each Lactobacillus sp. We identified 16 species of Lactobacillus by 16S rRNA gene sequence analysis, 10 of which could not be associated with disease. While Lactobacillus rhamnosus, Lactobacillus gasseri, and Lactobacillus paracasei were associated with infections, L. gasseri was also a common colonizing/contaminating species. Lactobacillus casei, Lactobacillus johnsonii, and Lactobacillus delbrueckii were associated with at least one infection. Species commonly used in probiotic products (e.g., L. rhamnosus and L. casei) were identical, by 16S rRNA gene sequencing, to our isolates associated with disease. Human isolates of Lactobacillus spp. have differing site associations and levels of clinical significance. Knowing the niche and pathogenic potential of each Lactobacillus sp. can be of importance to both clinical microbiology and the food and probiotic supplement industry. PMID:24131686

    Full Text Available Background & Objectives: Considering new pandemic attack with new emerging (H1N1 influenza virus, the study was designed for evaluating clinical and epidemiologic characteristics of patients in Imam Khomeini hospital, admitted with presumptive diagnosis of H1N1 influenza . In all of the patients clinical and paraclinical findings and outcome (including mortality rate and definitive diagnosis were evaluated. Bed occupancy rate in infectious disease ward and ICU and also mean days of admission were calculated.   Methods: This is a cross sectional study . All 118 patients with acute respiratory symptoms and possible diagnosis of emerging H1N1 influenza that had been admitted at least 24 hours in hospital from 20 October to 1 February 2009 were enrolled in the study. Data collection was done based on questionnaires, with a team other than researchers. The questionnaire included demographic data , clinical symptoms , laboratory findings , radiographic manifestations and outcome of patients. Data analysis was performed with SPSS software version16.   Results: A total of 118 patients were studied: 71 patients ( 60.2% were female and 47 patients ( 39.8% were male. Mean ( ± SD age of admitted patients was 33.81 ± 15.64 years old. The most of admitted patients were in age range of 15 to 30 years old. The most common findings in CXR were bilateral respiratory consolidations and the most common symptoms were fever, weakness and fatigue. About 12.7% of patients had diarrhea. Leukopenia (WBC 10000 occurred respectively in 4.58% and 33.2% of cases . Nine patients (7% were admitted in ICU. I n 21 patients (18% RT-PCR test results were positive and three of these patients had been admitted in ICU. In patients admitted in ICU while their diagnosis was confirmed, mortality was 33%. 48.3% of patients had at least one predisposing medical condition . Total admission days were 577 days, consisting 519 days in infectious disease ward and 58 days in ICU. Average of

    In 5 years of experience at the Instituto Nacional de la Comunicacion Humana, 302 clinical histories showed the diagnosis of dyslexia. The following parameters were studied: age, sex, heredofamilial history, gestation, psychomotor development, clinical picture, examination of the language (type, reading, spontaneous writing, dictation, mathematic concepts), laterality, scholarship, scholar failures, psychological study. The following results were obtained: Dyslexia was more important or frequent between 5 to 8.9 years of age. Males predominated 3:1. The heredofamilial history was important. Dyslexia prevailed in products of the first gestations. A high disturbance was found in the psychomotor development of a large percent of dyslexic patients. Examination of language was also important. Dyslexia was more frequent in right-handed patients. Scholar failures in one or more instances were found. The psychological study must be done. If dyslexia is diagnosed on time, it may be prevented and all unwanted sequelae may be avoided.

    Leptospirosis is a common condition in Wallis and Futuna, and the definitive diagnosis needs to be established urgently at the first patient consultation, which is usually one to two days after the onset of clinical signs. As a diagnostic aid, a composite index was established based on data from 338 patients seen by the Wallis and Futuna admissions services between 2008 and 2015. The data taken into account include: age and sex of the patient, their home island, the consultation period and the results of leukocytes, platelets, CRP, creatinine and GGT tests combined with 2 major clinical signs, headache and conjunctival suffusion. Then 5 threshold limits were defined for this index, which indicates from very low risk to almost certain biologically confirmed leptospirosis. Other febrile diseases responsible for thrombocytopenia are not found in Wallis and Futuna, which probably explains the good statistical qualities of this index with a value of area under the curve equal to 0.821.

    Introduction Identification of yeast isolated from clinical specimens to the species level has become increasingly important. Ever-increasing numbers of immuno-suppressed patients, a widening range of recognized pathogens, and the discovery of resistance to antifungal drugs are contributing factors to this necessity. Material and methods A total of 487 yeast strains were studied for the primary isolation and presumptive identification, directly from clinical specimen. Efficacy of CHROMagar Candida has been evaluated with conventional methods including morphology on Corn meal–tween 80 agar and biochemical methods by using API 20 C AUX. Results The result of this study shows that CHROMagar Candida can easily identify three species of Candida on the basis of colonial color and morphology, and accurately differentiate between them i.e. Candida albicans, Candida tropicalis, and Candida krusei. The specificity and sensitivity of CHROMagar Candida for C. albicans calculated as 99%, for C. tropicalis calculated as 98%, and C. krusei it is 100%. Conclusion The data presented supports the use of CHROMagar Candida for the rapid identification of Candida species directly from clinical specimens in resource-limited settings, which could be very helpful in developing appropriate therapeutic strategy and management of patients.

    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 Abstract Background Acute myocarditis may mimic myocardial infarction, since affected patients complain of "typical" chest pain, the ECG changes are identical to those observed in acute coronary syndromes, and serum markers are increased. We describe a case series of presumptive myocarditis with ST segment elevation on admission ECG. Methods and Results From 1998 to 2009, 21 patients (20 males; age 17-42 years were admitted with chest pain, persistent ST segment elevation, serum enzyme and troponine release. All but one patients had fever and flu-like symptoms prior to admission. No abnormal Q wave appeared in any ECG tracing, and angiography did not show significant coronary artery disease. Patients remained asymptomatic at long term follow-up, except 2 who experienced a late relapse, with the same clinical, electrocardiographic and serum findings as in the first clinical presentation. Conclusion Presumptive myocarditis of possible viral origin characterized by ST elevation mimicking myocardial infarction, good short term prognosis and some risk for recurrence is relatively frequent in young males and appears as a distinct clinical condition.

    captación activa de casos en la comunidad.OBJECTIVE: To validate a method for the presumptive diagnosis of cutaneous leishmaniasis based on the observation of clinical-epidemiological criteria, carried out by community health workers in three endemic municipalities in Santander, a department in northeastern Colombia. METHODS: This evaluation study of diagnostic technologies was based on a cross-sectional sampling of suspected cases of cutaneous leishmaniasis in the municipalities of Rionegro, El Playón, and Landázuri. After being trained, the community health workers carried out the presumptive diagnoses of cutaneous leishmaniasis between October 2004 and November 2005. At the time of diagnosis, the health workers also collected samples for confirmatory diagnosis through Field's stain method, culturing, and polymerase chain reaction. Four criteria were used to assess the validity of the presumptive diagnoses carried out by the health workers: sensitivity, specificity, positive predictive value, and negative predictive value. Replicability among the health workers was estimated through their observed level of agreement. RESULTS: According to the laboratory tests, of the 196 patients studied, 33 (16.8% were negative and 163 (83.2% were positive. For all the levels of certainty of the clinical diagnosis, the sensitivity was between 52% and 98% (k(1, 0 = 39.0% and the specificity between 9% and 55% (k(0, 0 = 14.0%. The area under the receiver operating characteristic curve was 56.5% (95% confidence interval: 45.6% to 67.4%. The proportion of positive agreement and of negative agreement was 86.3% and 43.5%, respectively. CONCLUSIONS: The sensitivity of the presumptive diagnosis carried out by the health workers surpasses that of the parasitological diagnostic methods generally used in the three endemic areas, but its specificity is much lower. Even though this approach is not useful as a diagnostic test for cutaneous leishmaniasis or as a criterion for deciding to proceed

    Breast cancer is the most common malignant neoplasm in women, and 6% will develop it during their normal life expectancy. There is a group who have a high risk of developing breast cancer. The recent improvement in cure rates seems to be jue chiefly to earlier diagnosis rather than to improved methods of therapy. The physician, by careful periodic breast examinations and by the judicious use of diagnostic aids such as mammography and thermography, especially in the high risk group, has a golden opportunity to pick up cancer in a localized stage where the prognosis for cure with appropriate therapy is excellent. A tentative diagnosis of breast cancer (Table XI) can be made with a fair degree of accuracy by taking a careful history, utilizing and combining available statistics about the frequency, median age, characteristic symptom complexes of the common breast lesions and factors related to a high mammary carcinoma risk, and by a systematic and thorough breast examination supplemented with diagnostic aids when appropriate. However, biopsy and histologic examination is mandatory in all patients with a) true, three dimentional, dominant lumps even if diagnostic aids are negative except for cysts which can be safely aspirated under controlled conditions; b) suspicious lesions found by diagnostic aids even though there are no clinical findings; c) serous, serosanguineous, bloody, or watery nipple discharge; and d) other signs of cancer, i.e. eczema of the nipple, axillary adenopathy, etc., in order to determine with absolute accuracy whether the lesion is benign or malignant.

    Full Text Available The correct and complete diagnosis is essential for the adequate care and the favourable clinical evolution of the patients with head trauma. Purpose: To identify the error rate in the clinical diagnosis of head injuries as shown in comparison with the autopsy diagnosis and to identify the most common sources of error. Material and method: We performed a retrospective study based on data from the medical files and the autopsy reports of patients with head trauma who died in the hospital and underwent forensic autopsy. We collected: demographic data, clinical and laboratory data and autopsy findings. To quantify the concordance rate between the clinical diagnosis of death and the autopsy diagnosis we used a 4 classes classification, which ranged from 100% concordance (C1 to total discordance (C4 and two classes of partial discordance: C2 (partial discordance in favour of the clinical diagnosis- missing injuries in the autopsy reports and C3 (partial discordance in favor of the necroptic diagnosis- missing injuries in the medical files. Data were analyzed with SPSS version 20.0. Results: We analyzed 194 cases of death due to head injuries. We found a total concordance between the clinical death diagnosis and autopsy diagnosis in 30.4% of cases and at least one discrepancy in 69.6% of cases. Increasing the duration of hospitalization directly correlates with the amount of the imaging investigations and these in turn correlates with an increased rate of diagnosis concordance. Among the patients with stage 3 coma who associated a spinal cord injury, we found a partial diagnosis discordance in 50% of cases and a total discordance in 50% of cases, possibly due to the need for conducting emergency imaging investigation and the need for surgical treatment. In cases with partial and total discordant diagnosis, at least one lesion was omitted in 45.1% of the cases. The most commonly omitted injuries in C2 cases were subdural hematoma, intracerebral

    Schizophrenia is a disease whose symptoms are shown to a little less than 1% at adolescence. Since the morbidity elucidation is not yet made many of psychiatry diseases including schizophrenia, a useful biological marker or image inspection, and a physiological inspection are not in diagnosis. About diagnosis of a psychiatric disorder, the symptoms study diagnostic method never must be used. Then, diagnosis needs to be made appropriately and carefully and differential diagnosis must also perform it exactly. It is because medical treatment may differ depending on diagnosis. If this is not made appropriately, it may lead to medication of an unnecessary and aimless antipsychotic. In this paper, diagnosis and differential diagnosis of schizophrenia, and clinical course were summarized.

    The purpose of the present study was to compare the current diagnostic clinical and laboratory approaches to women with vulvovaginal discharge complaint. The secondary outcomes were to determine the prevalence of infections in our setting and to look for the relation between vulvovaginal infections and predisposing factors if present. Premenopausal women applying to our gynecology outpatient clinic with vaginal discharge complaint were enrolled prospectively into the study. Each patient evaluated clinically with direct observation of vaginal secretions, wet mount examination, whiff test, vaginal pH testing and chlamydia rapid antigen test. Each patient also evaluated microbiologically with vaginal discharge culture and gram staining. Clinical diagnosis was compared with the microbiological diagnosis (the gold standard). Diagnostic accuracy was measured with sensitivity, specificity, positive (ppv) and negative predictive values (npv). 460 patients were included in the study. 89.8% of patients received a clinical diagnosis whereas only 36% of them had microbiological diagnosis. The sensitivity, specificity, ppv, npv of clinical diagnosis over microbiological culture results were 95, 13, 38, 82%, respectively. The most commonly encountered microorganisms by culture were Candida species (17.4%) and Gardnerella vaginalis (10.2%). Clinically, the most commonly made diagnoses were mixed infection (34.1%), bacterial vaginosis (32.4%) and fungal infection (14.1%). Symptoms did not predict laboratory results. Predisposing factors (DM, vaginal douching practice, presence of IUD and usage of oral contraceptive pills) were not found to be statistically important influencing factors for vaginal infections. Clinical diagnosis based on combining symptoms with office-based testing improves diagnostic accuracy but is insufficient. The most effective approach also incorporates laboratory testing as an adjunct when a diagnosis is in question or treatment is failing.

    Primary cultures of clinical material were screened for the presence of colonies suspected of being Streptococcus agalactiae (Lancefield group B). Sixty-three such cultures and 108 other isolates of beta-hemolytic streptococci (groups A, C, and G), encountered during the first 3 months of the investigation, were studied by Lancefield grouping, sodium hippurate hydrolysis, and a standardized CAMP test. All streptococci were inoculated perpendicularly to streaks of a beta-toxin-producing staphylococcus on sheep blood agar plates and incubated aerobically in a candle jar and anaerobically at 37 C. Plates were examined after 5 to 6 and 18 h of incubation. The production of a distinct "arrowhead" of hemolysis was indicative of a positive CAMP reaction. All group B streptococci produced a positive CAMP reaction in the candle jar or anaerobically, usually within 5 to 6 h, and aerobically after 18 h of incubation. All group A streptococci produced a positive reaction only under anaerobic conditions. Groups C and G streptococci were negative under all atmospheres. The CAMP reaction is a prompt and reliable procedure for the presumptive identification of group B streptococci when a candle jar atmosphere is used during incubation.

    2011-04-01

    This article reviews the evaluation of the hip including the clinical history and physical examination. As our understanding of hip pathology evolves, and arthroscopic and other minimally invasive operative techniques improve, the focus is shifting toward earlier identification of hip pathology. Risk factors for the development of arthritis are now well established and include femoral acetabular impingement, labral tearing, developmental dysplasia, and slipped capital femoral epiphysis. Emerging treatment options may address these conditions in the early stages and prevent or slow the progression of hip degeneration. It is vitally important to elucidate intra-articular versus extra-articular pathology of hip pain in every step of the patient encounter: history, physical examination, and imaging.

  14. Clinical features and diagnosis of venous thrombosis

    Hirsh, J.; Hull, R.D.; Raskob, G.E.

    1986-12-01

    The clinical diagnosis of venous thrombosis is inaccurate because the clinical findings are both insensitive and nonspecific. The sensitivity of clinical diagnosis is low because many potentially dangerous venous thrombi are clinically silent. The specificity of clinical diagnosis is low because the symptoms or signs of venous thrombosis all can be caused by nonthrombotic disorders. A current approach to the diagnosis of clinically suspected venous thrombosis favors the use of impedance plethysmography over Doppler ultrasonography as the main test for this disorder. This is because impedance plethysmography is precise and objective, whereas the interpretation of Doppler ultrasonography is subjective and requires considerable skill and experience to form reliable diagnoses. The use of serial impedance plethysmography has been evaluated recently in a prospective study. The rationale of repeated impedance plethysmography evaluation is based on the premise that calf vein thrombi are only clinically important when they extend into the proximal veins, at which point detection with impedance plethysmography is possible. Therefore, by performing repeated examinations with impedance plethysmography in patients with clinically suspected venous thrombosis, it is possible to identify patients with extending calf vein thrombosis who can be treated appropriately. Impedance plethysmography is performed immediately on referral; if it is positive in the absence of clinical conditions that are known to produce falsely positive results, the diagnosis of venous thrombosis is established, and the patient is treated accordingly. If the result of the initial impedance plethysmography evaluation is negative, anticoagulant therapy is withheld, and impedance plethysmography is repeated the following day, again on day 5 to 7 and on day 10 to 14. 87 references.

    A chalazion, localized lipogranulomatous inflammation of the eyelid, may simulate various eyelid lesions. This study was conducted to determine the accuracy of the clinical diagnosis of chalazion and demonstrate the importance of histopathological confirmation of the diagnosis. Histopathological diagnoses of 1060 cases with the clinical diagnosis of chalazion, submitted to the Henry C Witelson Ophthalmic Pathology Laboratory and Registry between September 1993 and December 2001, were retrospectively evaluated. Discrepancies between clinical and histopathological diagnoses were classified. A total of 1033 (97.4%) of the 1060 cases were clinically diagnosed as primary and the remaining 27 (2.6%) as recurrent chalazions. Agreement was noted between clinical and histopathological diagnoses in 992 (93.6%) cases. Of the 68 (6.4%) clinically misdiagnosed cases, 15 (1.4%) were found to be malignant, two (0.2%) premalignant, and 51 (4.8%) benign conditions. Sebaceous cell carcinoma was the most commonly missed malignancy (12 cases, 1.1%) followed by basal cell carcinoma (three cases, 0.3%). Premalignant lesions, which masqueraded as chalazion, were chronic inflammation with cellular atypia and mitotic figures (two cases, 0.2%). Of these 17 cases with premalignant and malignant histopathologies, only six (35.3%) had a clinical diagnosis of recurrent chalazion, whereas the others (64.7%) were primary cases. Of the various benign conditions that were misdiagnosed as chalazion, different types of chronic inflammation (24 cases, 2.2%) were the most frequent. A number of different benign, premalignant, and malignant conditions may clinically masquerade as a chalazion. Delayed diagnosis and treatment of sebaceous cell carcinoma, which is the most frequently missed malignancy, may be life threatening for the patient. Therefore, all chalazion specimens, primary or recurrent, should be submitted for histopathological examination.

    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.

    Our experience in pancreatic scintigraphy is presented in this paper. It was used as radioactive substance 75 semetionina. 21 patients with pancreatic pathology and 6 controls constituted the clinical material. The scintigraphy studies showed an homogenous distribution of the radioactive material in the control group. In 7 cases a defect of concentration was showed. The diagnosis of carcinoma were made with surgery in all of them. Similar findings were demonstrated in cases of pancreatic pseudocyst. Irregular distribution was noted in patients with pancreatitis. We concluded that in same instances pancreatic scintigraphy can be useful for differential diagnosis in the clinical field.

    Full Text Available OBJECTIVE: To determine the sensitivity and specificity of a Computer Aided Diagnosis (CAD program for scoring chest x-rays (CXRs of presumptive tuberculosis (TB patients compared to Xpert MTB/RIF (Xpert. METHOD: Consecutive presumptive TB patients with a cough of any duration were offered digital CXR, and opt out HIV testing. CXRs were electronically scored as normal (CAD score ≤ 60 or abnormal (CAD score > 60 using a CAD program. All patients regardless of CAD score were requested to submit a spot sputum sample for testing with Xpert and a spot and morning sample for testing with LED Fluorescence Microscopy-(FM. RESULTS: Of 350 patients with evaluable data, 291 (83.1% had an abnormal CXR score by CAD. The sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV of CXR compared to Xpert were 100% (95%CI 96.2-100, 23.2% (95%CI 18.2-28.9, 33.0% (95%CI 27.6-38.7 and 100% (95% 93.9-100, respectively. The area under the receiver operator curve (AUC for CAD was 0.71 (95%CI 0.66-0.77. CXR abnormality correlated with smear grade (r = 0.30, p<0.0001 and with Xpert CT(r = 0.37, p<0.0001. CONCLUSIONS: To our knowledge this is the first time that a CAD program for TB has been successfully tested in a real world setting. The study shows that the CAD program had high sensitivity but low specificity and PPV. The use of CAD with digital CXR has the potential to increase the use and availability of chest radiography in screening for TB where trained human resources are scarce.

    Snake bites represent a serious public health risk in many regions of the globe, especially in tropical areas. Clinical signs and postmortem changes are well described in human and other mammalian species. However, detailed case reports about venomous snake attacks in avian species are limited. This report describes presumptive fatal envenomations in three psittacines caused by pit vipers in a Brazilian zoo. In one case, a Brazilian lancehead (Bothrops moojeni) was captured in the aviary. In all three cases the dermis around the suspected snake bite area exhibited hemorrhages and edema. Histologically, degeneration and necrosis of subcutaneous musculature were observed. Lung, heart, and kidneys displayed focal hemorrhages. The local changes are similar to those described for mammalian patients including humans. However, except for the parenchymatous hemorrhages, additional external and internal gross and histopathological lesions were missing. After ruling out other causes, such as aggression and dicoumarinic intoxication, the presumptive diagnosis of snake envenomation was made. The smaller size and variabilities of pathophysiological effects of the venom in parrots might explain the different lesion patterns observed, compared with mammals. Possibly, the birds may have reacted differently to envenomation by pit vipers and died before the venom could cause macroscopic and histological changes often observed in mammals.

    Full Text Available Acromegaly and gigantism are due to excess GH production, usually as a result of a pituitary adenoma. The incidence of acromegaly is 5 cases per million per year and the prevalence is 60 cases per million. Clinical manifestations in each patient depend on the levels of GH and IGF-I, age, tumor size, and the delay in diagnosis. Manifestations of acromegaly are varied and include acral and soft tissue overgrowth, joint pain, diabetes mellitus, hypertension, and heart and respiratory failure. Acromegaly is a disabling disease that is associated with increased morbidity and reduced life expectancy. The diagnosis is based primarily on clinical features and confirmed by measuring GH levels after oral glucose loading and the estimation of IGF-I. It has been suggested that the rate of mortality in patients with acromegaly is correlated with the degree of control of GH. Adequately treated, the relative mortality risk can be markedly reduced towards normal.

    BACKGROUND Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information. METHODS Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations. RESULTS We identified seven obesity-related myths concerning the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals for weight loss, rapid weight loss, weight-loss readiness, physical-education classes, breast-feeding, and energy expended during sexual activity. We also identified six presumptions about the purported effects of regularly eating breakfast, early childhood experiences, eating fruits and vegetables, weight cycling, snacking, and the built (i.e., human-made) environment. Finally, we identified nine evidence-supported facts that are relevant for the formulation of sound public health, policy, or clinical recommendations. CONCLUSIONS False and scientifically unsupported beliefs about obesity are pervasive in both scientific literature and the popular press. (Funded by the National Institutes of Health.) PMID:23363498

    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.

    2004-01-01

    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

  9. Cugini's syndrome: its clinical history and diagnosis

    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

    the larvae migrate through the capillaries, taking up residence in different tissues. Clinical manifestations are associated with mechanical and/or reaction damage caused by these parasites larvae. Clinical diagnosis is difficult. The method applied in this work is the demonstration of antibodies against the helminth in the blood of children, target host population of this parasitic disease. An ELISA test was performed using T. canis larval excretory-secretory products as antigen. A total of 100 children presumptively diagnosed of toxocariasis that had been derived from different services of the Regional Children’s Hospital for complementary studies, were included in the analysis. The test detected two different populations: infected (59 and non-infected (41. The statistical analysis showed a non significant association between infection and sex (p = 0.279. Infected subjects tended to be older than the non infected (p = 0.009. Eosinophilia was detected in 100% of seropositive children and in 85.2% of the seronegative. There was no significant association between infection and leucocytosis ( = 0.950. The association of these two parameters was significantly higher among infected patients (R = 0.918. Respiratory symptoms and signs were more frequently detected in the positive population (p = 0.05. Dogs tenancy was as frequent among infected as in the non infected homes (p = 0.53. According to these results, prevention, early diagnosis and opportune treatment for toxocariasis should be considered as prioritary health activities in this region.

    To evaluate the prevailing practice of presumptively diagnosing malaria in all cases of febrile illness in a clinic serving a refugee population on the Thai-Myanmar border A retrospective review of 3,506 patient charts from December 1993 through June 1994 at the MaeSot medical clinic to compare clinical signs of malaria to blood smear findings. Patients presenting without fever were assumed not to have malaria; the remaining 2,111 patients presenting with fever had blood smears examined for malaria infection. Fever alone sufferedfrom poorpositive predictive value (54.7 percent) and specificity (59.3 percent). When fever was combined with hepatosplenomegaly and anemia, the positive predictive value and specificity improved (84.5 percent and 98.5 percent, respectively). However, this combination also resulted in an unacceptably poor sensitivity (16.5 percent) and false negative error rate (835/1,000). CONCLUSIONS. In this nonimmune refugee population, severe complications of falciparum malaria occur quickly and commonly; aggressive chemotherapy is necessary to reduce morbidity and mortality. Until laboratory facilities are made available, all cases offever should continue to be treated presumptively as malaria.

    Hyponatremia, defined as a serum sodium concentration <135mmol/l, is the most common water-electrolyte imbalance encountered in clinical practice. It can lead to a wide spectrum of clinical symptoms, from mild to severe or even life threatening, and is associated with increased mortality, morbidity and length of hospital stay. Despite this, the management of hyponatremia patients remains problematic. The prevalence of hyponatremia in a wide variety of conditions and the fact that hyponatremia is managed by clinicians with a broad variety of backgrounds have fostered diverse institution- and specialty-based approaches to diagnosis and treatment. To obtain a common and holistic view, the European Society of Intensive Care Medicine (ESICM), the European Society of Endocrinology (ESE) and the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA), represented by European Renal Best Practice (ERBP), have developed clinical practice guidelines on the diagnostic approach and treatment of hyponatremia as a joint venture of 3societies representing specialists with a natural interest in hyponatremia. In addition to a rigorous approach to the methodology and evaluation of the evidence, the document focuses on patient-positive outcomes and on providing a useful tool for clinicians involved in everyday practice. In this article, we present an abridged version of the recommendations and suggestions for the diagnosis and treatment of hyponatremia extracted from the full guide.

    Full text: Glycosylation is the enzymatic process that links saccharides to produce glycans, either free or attached to proteins. This is an enzyme-directed site-specific process, as opposed to the chemical reaction of glycation which is the result of addition of a sugar molecule to a protein or lipid molecule without the controlling action of an enzyme. Both protein modifications, however, can be used as clinical biomarkers for a variety of disorders including chronic alcoholism, diabetes or congenital disorders of glycosylation. The potential of ICPMS as a tool in the diagnosis of such diseases will be illustrated in the presentation. (author)

    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)

    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.)

    Behcet's Disease (BD) is classified among vasculitides. The aim of this review was to put together different known reports in order to help the reader to better understand the disease, to avoid the frequent misdiagnosis, and to decide the best treatment. Areas covered: a) Epidemiology: BD is rare, and is seen along the Silk Road, from 20 to 420/100,000 in Turkey and 80/100,000 in Iran, to 0.64/100,000 in the UK. b) Clinical manifestations: oral aphthosis is seen in more than 95% of patients, genital aphthosis (60-90%), skin (pseudofolliculitis/erythema nodosum, 40-90%), eyes (uveitis/retinal vasculitis, 45-90%), gastrointestinal (diarrhea/hemorrhage/perforation/pain, 4-38%), vascular (venous/arterial thrombosis, aneurysm, 2.2-50%), neurological (all kinds, especially meningo-encephalitis, 2.3-38.5%), and articular (arthralgia/arthritis/ankylosing spondylitis, 11.6-93%). c) Pathergy test is positive in some patients: 8.6% (in India) to 70.7% (in China). This data was extracted from the five nationwide surveys and the largest case series from BD conference reports and a Pubmed search. Expert commentary: Diagnosis is clinical but classification/diagnosis criteria may help. The best criteria for BD is the International Criteria for Behcet's Disease (ICBD). BD is a multisystem disease progressing by attacks and remissions. Each attack may resemble the preceding or it may be different in duration, severity, and the systems involved.

    Objective: To know the sensitivity of polymerase chain reaction (PCR) in pericardial fluid and response to antituberculous treatment (ATT) in PCR positive patients who were presumptively diagnosed and treated as tuberculous pericardial effusion. Methodology: This was a descriptive cross sectional study carried out from June 1, 2009 to 31 May 2010 at Cardiology Department, Lady Reading Hospital, Peshawar. Patients with presumptive diagnosis and receiving treatment for tuberculous pericardial effusion were included. Pericardial fluid sample was aspirated under fluoroscopy for the routine work up. The specimens were subjected to PCR detection of mycobacterium tuberculous DNA. Results: During 12 month study period, a total of 54 patients with large pericardial effusion presented to Cardiology department, Lady Reading Hospital, Peshawar. Of them, 46 patients fulfilled the criteria for presumptive diagnosis of tuberculous pericardial effusion. PCR for mycobacterium tuberculous DNA in pericardial fluid was positive in 45.7%(21). Patients were followed for three months. In PCR positive group, 01 patient while in PCR negative group 3 patients were lost to follow up. Among PCR positive patients 17(85%) while in PCR negative group 11(47.82%) patient responded to ATT both clinically and echo-cardio graphically. We found that patients who were PCR positive responded better to therapy than those who were PCR negative and this finding was statistically significant (p=0.035). Conclusion: PCR, with all its limitations, is potentially a useful diagnostic test in patients with presumptively diagnosed tuberculous pericardial effusion. A PCR positive patient responds better to therapy as compared to PCR negative patient. (author)

    Autoinflammatory syndrome is characterized by: 1) episodes of seemingly unprovoked inflammation, 2) the absence of a high titer of autoantibodies or auto-reactive T cells, and 3) an inborn error of innate immunity. In this decade, many autoinflammatory syndromes have been reported in Japan, and so many Japanese physicians have become aware of this syndrome. Monogenic autoinflammatory syndromes present with excessive systemic inflammation including fever, rashes, arthritis, and organ-specific inflammation and are caused by defects in single genes encoding proteins that regulate innate inflammatory pathways. The main monogenic autoinflammatory syndromes are familial Mediterranean fever (FMF), TNF receptor-associated periodic syndrome (TRAPS), mevalonate kinase deficiency (MKD), cryopyrin-associated periodic syndrome (CAPS), Blau syndrome, and pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome. We diagnosed these syndromes as clinical manifestations and performed genetic screening. Many serum cytokines are elevated in patients with autoinflammatory syndrome, but this is not disease-specific. The pathogeneses of many autoinflammatory syndromes are known to be related to inflammasomes, which are multiprotein complexes that serve as a platform for caspase 1 activation and interleukin-1β (IL-1β) and IL-18 muturation. Especially, NLRP3 inflammasomes may play a crucial role in the intiation and progression of FMF and CAPS. In the future, we hope to discover new clinical examinations which can provide evidence of inflammasome activation independent of genetic screening. In this issue, I introduce autoinflammatory syndromes and discuss the diagnosis and clinical examination of these syndromes.

    The mucopolysaccharidoses (MPS) are a group of rare (orphan) diseases, characterised by a deficiency of enzymes involved in the metabolism of glycosaminoglycans (GAGs) at lysosomal level. When there is a deficiency of a particular enzyme there is an accumulation of GAGs in the cells resulting in progressive cellular damage, which can affect multiple organ systems and lead to organ failure. Diagnosis is based on knowledge of the clinical manifestations, performing biochemical analyses to identify the type of GAG that is accumulating, and confirm the type of disorder with the corresponding enzymatic determination. Their identification is essential to initiate early treatment, taking into account that multidisciplinary management and enzyme replacement therapy is available for MPS I (Hurler syndrome), MPS II (Hunter syndrome), MPS IV (Morquio syndrome), and MPS VI (Maroteaux-Lamy syndrome. In this review, an analysis is made of each of these syndromes, as well as their diagnosis and treatment. Copyright © 2015 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U.

    Full Text Available The lecture gives basic information about psoriatic arthritis (PsA, a chronic inflammatory disease of the joints, spine, and enthesises from a group of spondyloarthritis. It describes the epidemiology of the disease and considers current ideas on its pathogenesis and factors influencing the development of PsA in psoriatic patients. The classification and clinical forms of PsA are presented. The major clinical manifestations of the disease are indicated to include peripheral arthritis, enthesitis, dactylitis, and spondylitis. The diagnosis of the disease is noted to be established on the basis of its detected typical clinical and radiological signs, by applying the CASPAR criteria. A dermatologist, rheumatologist, and general practitioner screen PsA, by actively detecting complaints, characteristic clinical and radiological signs of damage to the joints, and/or spine, and/or enthesises and by using screening questionnaires. There are data that patients with PsA are observed to be at higher risk for a number of diseases type 2 diabetes mellitus hypertension, coronary heart disease, obesity, metabolic syndrome, inflammatory bowel diseases, etc. The aim of current pharmacotherapy for PsA is to achieve remission or minimal activity of clinical manifestations of the disease, to delay or prevent its X-ray progression, to increase survival, to improve quality of life in patients, and to reduce the risk of comorbidities. The paper considers groups of medicines used to treat the disease, among other issues, information about biological agents (BA registered in the Russian Federation for the treatment of PsA. Most patients are mentioned to show a good response to this therapy option just 3–6 months after treatment initiation; however, some of them develop primary inefficiency. In this case, switching one BA to another is recommended. Some patients using a BA develop secondary treatment inefficiency, which is firstly due to the appearance of

    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.

    Implantation of the zygote outside the uterine cavity occurs in 2% of all pregnancies. The product of conception can be removed safely by laparoscopic surgery and be submitted for histological examination. The rate of ectopic pregnancies has increased from 0.5% in 1970 to 2% today. The prevalence of ectopic pregnancy in all women presenting to an emergency department with first-trimester bleeding, lower abdominal pain, or a combination of the 2 is between 6% and 16%. DESIGNATION: Workup of all localizations of ectopic pregnancies at a university department of obstetrics and gynecology. Comparison of diagnostic and therapeutic modalities from the surgical laparoscopic approach to nonsurgical, medical options. Tubal pregnancies: (1) to preserve tubal function, salpingotomy, partial salpingectomy followed by laparoscopic anastomosis, or fimbrial milking is performed. (2) Tubectomy or salpingectomy is performed only in severely damaged or ruptured tubes or if the patient does not desire further pregnancies. Nontubal ectopic pregnancies (ovarian pregnancy, ectopic abdominal pregnancy, interstitial or cornual pregnancy/rudimentary horn, intraligamental and cervical pregnancies) all require their own specific treatment. The predominant drug is methotrexate, but other systemic drugs, such as actinomycin D, prostaglandins, and RU 486, can also be applied. Tubal rupture is a complication of late diagnosed tubal pregnancy that is more difficult to treat conservatively and often indicates tubectomy or segmental resection. In 5% to 15% of treated ectopic pregnancy cases, remnant conception product parts may require a final methotrexate injection. This article is a review to aid clinical diagnosis of ectopic pregnancies that now can be diagnosed earlier and treated effectively by laparoscopic surgery.

    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

Shah Medical Institute and Research Centre, Sumandeep Vidyapeeth University, Vadodara, Gujarat, India; 2Department of Neurology, Cleveland Clinic Foundation, Cleveland, OH, USA Abstract: Hemicrania continua (HC is an indomethacin-responsive primary headache disorder which is currently classified under the heading of trigeminal autonomic cephalalgias (TACs. It is a highly misdiagnosed and underreported primary headache. The pooled mean delay of diagnosis of HC is 8.0 ± 7.2 years. It is not rare. We noted more than 1000 cases in the literature. It represents 1.7% of total headache patients attending headache or neurology clinic. Just like other TACs, it is characterized by strictly unilateral pain in the trigeminal distribution, cranial autonomic features in the same area and agitation during exacerbations/attacks. It is different from other TACs in one aspect. While all other TACs are episodic, HC patients have continuous headaches with superimposed severe exacerbations. The central feature of HC is continuous background headache. However, the patients may be worried only for superimposed exacerbations. Focusing only on exacerbations and ignoring continuous background headache are the most important factors for the misdiagnosis of HC. A large number of patients may have migrainous features during exacerbation phase. Up to 70% patients may fulfill the diagnostic criteria for migraine during exacerbations. Besides migraine, its exacerbations can mimic a large number of other primary and secondary headaches. The other specific feature of HC is a remarkable response to indomethacin. However, a large number of patients develop side effects because of the long-term use of indomethacin. A few other medications may also be effective in a subset of patients with HC. Various surgical interventions have been suggested for patients who are intolerant to indomethacin. Several aspects of HC

    Full Text Available Hepatic fibrosis is the common outcome of chronic liver diseases of various causes. At present, liver biopsy is the “gold standard” for the diagnosis of liver fibrosis, but it has limitations and is invasive, which leads to the development of noninvasive assessment of liver fibrosis. The article mainly introduces the technology and application of noninvasive diagnosis of liver fibrosis from the aspects of clinical manifestation, serology, and radiology. It has pointed out the clinical value of these noninvasive diagnosis techniques, and it discusses the progress in clinical research and its limitations for noninvasive diagnosis of liver fibrosis.

    Acute or chronic injury of the nervous system caused by xenobiotics can resemble primary disorders of the nervous system. In this study, four different cases that are characterized by unclear clinical presentation have been discussed; they required a detailed differential diagnostics using modern radiologic and electrophysiologic studies. Case 1. A young alcohol abuser was referred to the Acute Poisonings Unit at Wrocław with a presumptive diagnosis of methanol poisoning. Neither methanol nor ethylene glycol were detected in patient's serum and urine. During hospitalization in our ward he lost vision completely, and neurologic examination was consistent with a transverse spinal cord injury. Traumatic spinal cord injury coexisting with methanol poisoning, or even Devic's syndrome were considered in differential diagnosis. The MRI did not reveal a spinal cord injury, and the EMG showed severe demyelinating-axonal polyneuropathy. Finally the patient was diagnosed with methanol poisoning complicated by both loss of vision and severe alcoholic polyneuropathy. Case 2. A 27-year-old man was found unconscious in a street. A head CT revealed numerous small intracerebral hemorrhages, and patient's urine contained high concentration of amphetamine. A presumptive diagnosis of amphetamine poisoning complicated by intracranial hemorrhage was proposed. The repeat head CT revealed traumatic injury of the skull in a form of depression. Based on this result, the patient was diagnosed with a posttraumatic intracranial hemorrhage. Case 3. A young man with history of schizophrenia was transferred to our ward from a psychiatric hospital with a presumptive diagnosis of neuroleptic malignant syndrome complicated by rhabdomyolysis. Infection of the nervous system and focal lesions in the brain were ruled out with help of lumbar puncture and a brain MRI. After having obtained additional details of patient's history, it appeared that the patient had not been taking neuroleptics, and

    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

    This study considered 120 cases of localized gingival overgrowths that had been clinically diagnosed, surgically excised, and submitted for histopathological examination from 2000 to 2006. Data regarding the patient's age and gender and the lesion's anatomical location, clinical diagnosis, and recurrence were retrieved from case records. The percentage of concurrence and discrepancy between clinical and histopathological diagnosis was calculated using a discrepancy index. In 46.60% of cases, the diagnoses were in total agreement; discrepancies were noted in 53.40% of cases. The diagnosis of peripheral giant cell granuloma showed a high discrepancy (88.89%). Recurrence was seen in five cases. The high discrepancy between the clinical and histopathological diagnosis of localized gingival overgrowths indicates the need for a confirmatory histological examination for diagnosis and complete management of the lesion.

    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.

    Full Text Available Information obtained from the routine application of hydatid immunodiagnostic techniques in different clinical situations over a seven-year period is presented. The Immunoelectrophoresis test was used until it was replaced by the simpler, more sensitive and equally specific arc 5 double diffusion (DD5 test. Examination of sera from 1,888 patients with signs and/or symptoms compatible with hydatid disease revealed that the presurgical confirmation of Echinococcus granulosus infection is only obtained by detection of anti-antigen 5 antibodies. The latter were not found in 1,539 presumptive hydatidosis patients whose definitive diagnoses corresponded to other disease conditions. However, false positive latex agglutination test results were obtained in two cases. In all patients whose preoperative serum showed three or more uncharacteristic bands in the absence of anti-antigen 5 antibodies, hydatid cysts were found sur gically. DD5 testing of a fluid sample collected by puncture established its hydatid etiology. Post-operative monitoring of hydatidosis patients demonstrated that persistence of DD5-positivity two years after surgery established the presence of other cysts. Further evidence was obtained in patients with hydatid cysts in intrathoracic, abdominal or other locations associating cyst membrane integrity, antigen release and immunodiagnostic test positivity.Se presenta la información obtenida de la aplicación de las técnicas inmunodiagnósticas para hidatidosis en diferentes situaciones clínicas durante un período de 7 años.

    Full Text Available Objective: In this study, the aim was to analyze the histologic alterations in thirty dental pulps and correlate them with the clinical findings to verify agreement between the clinical and histopathologic diagnosis and contribute to knowledge about endodontic diagnosis. Methods: Using the methodology of Oliveira4, the pulpal conditions were clinically classified as normal, reversible pulpitis, pulpitis at the stage of transition, irreversible pulpitis and necrosis. Results: Lack of correlation was observed between the clinical and histopathologic diagnoses in the cases classified as reversible and at the stage of transition, which histologically consisted of irreversible lesions or degenerative alterations. All the cases clinically classified as irreversible corresponded to the histologic diagnoses. Conclusion: It was concluded that the correlation between clinical and histopathologic diagnosis of dental pulp was shown to be controversial, even though the semiotechnique used had been imperative for guidance about the irreversibility of pulpal lesion.

    Full Text Available Leslie A Sadownik University of British Columbia, Department of Obstetrics and Gynecology, Vancouver, BC, Canada Abstract: Chronic vulvar pain or discomfort for which no obvious etiology can be found, ie, vulvodynia, can affect up to 16% of women. It may affect girls and women across all age groups and ethnicities. Vulvodynia is a significant burden to society, the health care system, the affected woman, and her intimate partner. The etiology is multifactorial and may involve local injury or inflammation, and peripheral and or central sensitization of the nervous system. An approach to the diagnosis and management of a woman presenting with chronic vulvar pain should address the biological, psychological, and social/interpersonal factors that contribute to her illness. The gynecologist has a key role in excluding other causes for vulvar pain, screening for psychosexual and pelvic floor dysfunction, and collaborating with other health care providers to manage a woman's pain. An important component of treatment is patient education regarding the pathogenesis of the pain and the negative impact of experiencing pain on a woman's overall quality of life. An individualized, holistic, and often multidisciplinary approach is needed to effectively manage the woman's pain and pain-related distress.

    To evaluate the efficacy of S-adenosyl l-methionine (SAMe) in the treatment of clinically inferred canine osteoarthritis (OA). Six weeks, double-blinded, placebo-controlled, clinical trial. Dogs (n=33) with clinical signs, history, and orthopedic exams consistent with OA. Dogs were block randomized by body condition score (goniometry, and the Canine Brief Pain Inventory (CBPI) at the time of study entrance and at 3 and 6 weeks after entry. Groups were compared using parametric and nonparametric paired tests as appropriate, and numbers needed to treat (NNT) were calculated for the CBPI and peak vertical force (PVF). Both groups (n=15 placebo, n=18 SAMe) had a reduction in mean PVF (P=.02) and vertical impulse (VI; P=.06) from the 1st to 3rd visit. There was no significant difference between the placebo group and SAMe group for PVF, VI, or either part of the CBPI (Severity or Impact). The NNT at 6 weeks for the Severity score was 3, Impact score was 25, and PVF was 45. These data do not support the use of SAMe as an effective stand alone treatment for reducing clinical signs of OA, as measured by PVF, VI, goniometry, CBPI (both Severity and Impact), and examination score within 6 weeks of treatment. © Copyright 2011 by The American College of Veterinary Surgeons.

    In the absence of screening, most patients with lung cancer are not diagnosed until later stages, when the prognosis is poor. The most common symptoms are cough and dyspnea, but the most specific symptom is hemoptysis. Digital clubbing, though rare, is highly predictive of lung cancer. Symptoms can be caused by the local tumor, intrathoracic spread, distant metastases, or paraneoplastic syndromes. Clinicians should suspect lung cancer in symptomatic patients with risk factors. The initial study should be chest x-ray, but if results are negative and suspicion remains, the clinician should obtain a computed tomography scan with contrast. The diagnostic evaluation for suspected lung cancer includes tissue diagnosis, staging, and determination of functional capacity, which are completed simultaneously. Tissue samples should be obtained using the least invasive method possible. Management is based on the individual tumor histology, molecular testing results, staging, and performance status. The management plan is determined by a multidisciplinary team consisting of a pulmonology subspecialist, medical oncology subspecialist, radiation oncology subspecialist, and thoracic surgeon. The family physician should remain involved with the patient to ensure that patient priorities are supported and, if necessary, to arrange for end-of-life care.

    2012-05-01

    Disseminated intravascular coagulation (DIC) is a serious and relatively uncommon complication of induced or spontaneous abortion or delivery. Occasionally, it has been reported in the absence of predisposing conditions. Little information in the literature describing idiopathic DIC or the treatment of patients with DIC exists. From 2002 through 2008, 24 cases of presumptive idiopathic DIC occurred following dilation and evacuation (D&E) abortion between 13 5/7 and 23 6/7 weeks' estimated gestational age at a Midwestern ambulatory surgical center. The characteristics of each patient, their pregnancies and surgical experiences were examined and compared with a temporally matched control group of D&E patients. We explored whether the index cases had a predominance of any historical, clinical or reproductive characteristics compared with controls matched for demographic and reproductive landmarks. Overall incidence of presumptive idiopathic DIC was 1.8 per 1000 D&E cases. Compared with matched controls, there was a greater likelihood of DIC with more advanced gestation (p=.009); no case of DIC was under 17 weeks' gestational age. Increased bleeding occurred at a mean time of 153 min after completion of surgery (range, 55-491 min; median, 131 min). Nineteen of 24 cases were successfully treated at the surgical center after receiving 6 to 8 units of fresh-frozen plasma (FFP); 5 cases were transferred to a hospital for further treatment. The abnormal bleeding of presumptive DIC typically begins to appear within 2 h after uncomplicated D&E and is more likely to occur at 17 weeks' estimated gestational age and more. With rapid diagnosis and treatment, most patients were able to be treated in an outpatient setting with up to 6 to 8 units of FFP and rehydration. Copyright © 2012 Elsevier Inc. All rights reserved.

    To review the management of a cohort of patients with positive treponemal serology and psychiatric and/or neurological disorders. A retrospective case note review of 172 patients with positive treponemal serology attending the Patrick Clement's Clinic, Central Middlesex Hospital between December 1990 and November 1995 was performed. 101 men and 71 women were new attenders diagnosed with positive treponemal serology. A neurological problem was identified in 27 patients (12 women and 15 men) with psychiatric and/or neurological disorders, of whom 20 (six women and 14 men) underwent investigation of the cerebrospinal fluid (CSF). With the medical history and results of CSF-RPR and FTA tests, white cell count (WCC), and total protein level in the CSF, 10 patients (eight men and two women) were diagnosed with likely neurosyphilis and 17 with neurological disorders not thought to be caused by syphilis. The clinical features in those having neurosyphilis were sensorineural hearing loss (n = 5) and tabes dorsalis (n = 5). In the seven patients diagnosed with neurosyphilis who underwent CSF examination one patient had a reactive CSF-FTA, elevated protein, and elevated WCC; one patient had a reactive CSF-FTA and RPR with elevated protein; the total protein only was elevated in three cases and the WCC elevated in one case. Nine of the 10 patients with neurosyphilis received adequate neurosyphilitic treatment; one patient was lost to follow up. The management of patients with positive treponemal serology and psychiatric and/or neurological disorders was consistent. Patients with suspected neurosyphilis or patients with neurological signs compatible with neurosyphilis (who did not undergo CSF examination) were treated with adequate neurosyphilitic therapy.

    Three weanling Thoroughbred fillies were presented during autumn with depression, muscle rigidity and, in one case, colic symptoms and cardiovascular shock. All fillies had abnormal physical examinations that included elevated heart rates and respiratory rates coupled with muscle rigidity through the back and rump. Biochemistry revealed markedly elevated creatinine kinase and aspartate aminotransferase which indicated a myopathy. All three horses were diagnosed with presumptive equine atypical myopathy. The horses received supportive therapy as per the literature available at the time regarding this condition; two responded to supportive therapy and survived, and one was euthanased due to a rapid deterioration in clinical status. Following post mortem of one case, histology of the trapezius muscle demonstrated an acute, severe myofibre degeneration. Atypical myopathy and a very similar disorder termed seasonal pasture myopathy in North America are potentially fatal, pasture-related syndromes that have been described in Europe and America but have not been previously described in New Zealand. This report describes three presumptive cases of this unique syndrome in New Zealand for the first time; it outlines the characteristics of the condition; and includes recently published information regarding diagnosis and treatment.

    Hemoglobinopathies are among the most common inherited diseases around the world. They have become much more common recently in northern and central Europe, including Germany, due to immigration. Selective review of the literature with consideration of national guidelines. The hemoglobinopathies encompass all genetic diseases of hemoglobin. They fall into two main groups: thalassemia syndromes and structural hemoglobin variants (abnormal hemoglobins). α- and β-thalassemia are the main types of thalassemia; the main structural hemoglobin variants are HbS, HbE and HbC. There are many subtypes and combined types in each group. The highly variable clinical manifestations of the hemoglobinopathies range from mild hypochromic anemia to moderate hematological disease to severe, lifelong, transfusion-dependent anemia with multiorgan involvement. Stem-cell transplantation is the preferred treatment for the severe forms of thalassemia. Supportive, rather than curative, treatment consists of periodic blood transfusions for life, combined with iron chelation. Drugs to treat the symptoms of sickle-cell disease include analgesics, antibiotics, ACE inhibitors and hydroxyurea. Blood transfusions should be given only when strictly indicated. More than 90% of patients currently survive into adulthood. Optimally treated patients have a projected life span of 50 to 60 years. Hemoglobinopathies are a public health issue in today's multiethnic German population. Adequate care of the affected patients requires a wide variety of diagnostic and therapeutic measures.

    Full Text Available Most clinicians universally acknowledge the difficulty of establishing a precise clinical diagnosis of the pathological status of the pulpal-dentinary organ, considering both the diversity of the etiological factors and especially the different histopatological forms that may characterize the same lesion. The aim of the present investigation is to identify and quantify the precision of the presumtive diagnosis established on the basis of clinical data and of paraclinical exams, comparatively with the results of the morphopathological work, which establishes the final diagnosis. There have been analyzed 45 teeth, 43 of which with various inflammatory pulpal problems, and 2 clinically-healthy teeth, extracted from orthodontic reasons. Taking advantage of the fact that, along with the development of the treatment, the dental pulp was also available, after its taking over, the surgical piece was prepared and microscopically examined, which permitted an undisputable morphopathological dignosis. To attain scientifically valid results, both the clinically and the morphopathologically obtained results were statistically interpreted by the non-parametric Wilcoxon test. If, from a clinical perspective, most of the cases were classified as mild hyperemia and partially serous acute pulpitis, the morphopathological examination viewed them as irreversible pulpitis, with major supurative and necrotic modifications. The actual diagnosis means cannot establish whether the pulpitis is a serous, a purulent or a combined manifestation in the various pulp sections.

    Full Text Available We have compared the searching of the presence of "honeycomb" structures by direct microscopy on wet mount preparations with the direct immunofluorescence (DIF for the diagnosis of Pneumocystis carinii pneumonia (PCP in 115 bronchoalveolar (BAL fluids. The samples belonged to 115 AIDS patients; 87 with presumptive diagnosis of PCP and 28 with presumptive diagnosis other than PCP. The obtained results were coincident in 114 out of 115 studied samples (27 were positive and 87 negative with both techniques. A higher percentage of positive results (32.18% among patients with presumptive diagnosis of PCP with respect to those with presumptive diagnosis other than PCP (3.57% was observed. One BAL fluid was positive only with DIF, showed scarce and isolated P. carinii elements and absence of typical "honeycomb" structures. The searching for "honeycomb" structures by direct microscopy on wet mount preparations could be considered as a cheap and rapid alternative for diagnosis of PCP when other techniques are not available or as screening test for DIF. This method showed a sensitivity close to DIF when it was applied to BAL fluids of AIDS patients with poor clinical condition and it was performed by an experienced microscopist.

    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.) [de

    Laser technology is now ubiquitous in science, business, the arts, the military, industry, telecommunications, entertainment and medicine. It is increasingly finding a useful place in dentistry to offer the potential for practical solutions to managing difficult clinical problems. Research into the clinical use of lasers in diagnostic and therapeutic dental procedures has escalated rapidly in recent years. Laser technology has revolutionized the treatment of dental caries. This article reviews the role of laser technology in the clinical management of caries, early caries diagnosis and treatment planning decision making, caries prevention, soft tissue management, fluorescence aided caries elimination and fluorescence feedback-controlled selective caries removal. Laser technology plays a vital role in enhancing caries diagnosis and therapy.

  10. Clinical guideline for diagnosis and management of melioidosis

    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.

  11. Clinical and Laboratory Diagnosis of Dengue Virus Infection.

    Infection with any of the 4 dengue virus serotypes results in a diverse range of symptoms, from mild undifferentiated fever to life-threatening hemorrhagic fever and shock. Given that dengue virus infection elicits such a broad range of clinical symptoms, early and accurate laboratory diagnosis is essential for appropriate patient management. Virus detection and serological conversion have been the main targets of diagnostic assessment for many years, however cross-reactivity of antibody responses among the flaviviruses has been a confounding issue in providing a differential diagnosis. Furthermore, there is no single, definitive diagnostic biomarker that is present across the entire period of patient presentation, particularly in those experiencing a secondary dengue infection. Nevertheless, the development and commercialization of point-of-care combination tests capable of detecting markers of infection present during different stages of infection (viral nonstructural protein 1 and immunoglobulin M) has greatly simplified laboratory-based dengue diagnosis. Despite these advances, significant challenges remain in the clinical management of dengue-infected patients, especially in the absence of reliable biomarkers that provide an effective prognostic indicator of severe disease progression. This review briefly summarizes some of the complexities and issues surrounding clinical dengue diagnosis and the laboratory diagnostic options currently available. © The Author 2017.

    1990-04-01

    The diagnostic efficiency of the Millon Clinical Multiaxial Inventory (MCMI) was examined with regard to the diagnosis of DSM-III axis II personality disorders by practicing psychiatrists. The MCMI displayed fairly good sensitivity but poor specificity and predictive power regarding the diagnosis of any personality disorder. Two possible explanations were offered: a) axis I psychopathology inflates scores on the MCMI personality disorder scales and causes an overdiagnosis of personality disorders by the test; or b) there is an under-recognition of axis II personality disorders (especially in the context of obvious axis I psychopathology) by the average practicing clinician.

    2014-01-01

    Full Text Available Takotsubo cardiomyopathy is rapidly reversible heart failure syndrome that usually mimics the symptoms of acute myocardial infarction with the characteristic regional wall-motion abnormalities (classically with a virtual apical ballooning caused by hypokinetic or akinetic apical or midventricular myocardium and hypercontraction of the basal segments and absence of obstructive coronary artery disease. TC is usually associated with identifiable emotional, psychological or physical stress event and most commonly appears in postmenopausal women. The certain pathophysiological mechanism remains unknown. However, the central hypothesis is supported by the excess of catecholamines and hyperactivity of nervous system. In the last decades the frequency of the TC diagnosis is increasing rapidly but at the initial presentation the diagnosis remains challenging due to the close similarities between TC and ST elevation myocardial infarction clinical presentations that consider TC as an important part of differential diagnosis in acute coronary syndrome.

    2017-04-07

    The development of circulating autoantibodies able to inhibit some coagulation proteins induces severe or even life-threatening bleeding. This disorder is called acquired haemophilia. This is a rare disease, although its impact may be underestimated because of the lack of records, the lack of knowledge by many specialists, the complexity of the laboratory diagnosis and, finally, because of the fulminant clinical presentation that often precludes diagnosis. Several studies established that mortality ranges between 9 and 33%. Not only haematologists but all physicians should be trained to follow the right steps to diagnose these patients as soon as possible in order to reduce such mortality rates. This review approaches the basic concepts dealing with the diagnosis and management of these patients and intends to assist physicians in identifying patients under suspicion of acquired haemophilia to correctly manage them and refer them to the appropriate Haemostasis Unit.

    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)

    Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient's condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology.

    2004-01-01

    Clinical pathologists use descriptive terms or modifiers to express the probability or likelihood of a cytologic diagnosis. Words are imprecise in meaning, however, and may be used and interpreted differently by pathologists and clinicians. The goals of this study were to 1) assess the frequency of use of 18 modifiers, 2) determine the probability of a positive diagnosis implied by the modifiers, 3) identify preferred modifiers for different levels of probability, 4) ascertain the importance of factors that affect expression of diagnostic certainty, and 5) evaluate differences based on gender, employment, and experience. We surveyed 202 clinical pathologists who were board-certified by the American College of Veterinary Pathologists (Clinical Pathology). Surveys were distributed in October 2001 and returned by e-mail, fax, or surface mail over a 2-month period. Results were analyzed by parametric and nonparametric tests. Survey response rate was 47.5% (n = 96) and primarily included clinical pathologists at veterinary schools (n = 58) and diagnostic laboratories (n = 31). Eleven of 18 terms were used "often" or "sometimes" by >/= 50% of respondents. Broad variability was found in the probability assigned to each term, especially those with median values of 75 to 90%. Preferred modifiers for 7 numerical probabilities ranging from 0 to 100% included 68 unique terms; however, a set of 10 terms was used by >/= 50% of respondents. Cellularity and quality of the sample, experience of the pathologist, and implications of the diagnosis were the most important factors affecting the expression of probability. Because of wide discrepancy in the implied likelihood of a diagnosis using words, defined terminology and controlled vocabulary may be useful in improving communication and the quality of data in cytology reporting.

    Retinal vasculitis is a sight-threatening inflammatory eye condition that involves the retinal vessels. Detection of retinal vasculitis is made clinically, and is confirmed with the help of fundus fluorescein angiography. Active vascular disease is characterized by exudates around retinal vessels resulting in white sheathing or cuffing of the affected vessels. In this review, a practical approach to the diagnosis of retinal vasculitis is discussed based on ophthalmoscopic and fundus fluorescein angiographic findings.

    Medicine is one of the fields of knowledge that would most benefit from a closer interaction with Computer studies and Mathematics by optimizing complex, imperfect processes such as differential diagnosis; this is the domain of Machine Learning, a branch of Artificial Intelligence that builds and studies systems capable of learning from a set of training data, in order to optimize classification and prediction processes. In Mexico during the last few years, progress has been made on the implementation of electronic clinical records, so that the National Institutes of Health already have accumulated a wealth of stored data. For those data to become knowledge, they need to be processed and analyzed through complex statistical methods, as it is already being done in other countries, employing: case-based reasoning, artificial neural networks, Bayesian classifiers, multivariate logistic regression, or support vector machines, among other methodologies; to assist the clinical diagnosis of acute appendicitis, breast cancer and chronic liver disease, among a wide array of maladies. In this review we shift through concepts, antecedents, current examples and methodologies of machine learning-assisted clinical diagnosis.

    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

    Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN) is a rare and often fatal spectrum of mucocutaneous diseases usually attributable to severe adverse drug reactions. Burn units are referral centers for patients at the most extreme end of the disease continuum. Our burn center admits a much higher percentage of TEN (>30% BSA) cases than reported in most prior reviews. The purpose of this study was to analyze the diagnostic and prognostic value of variables collected on referred SJS/TEN patients. We retrospectively analyzed 94 patients admitted to our unit with a presumptive SJS/TEN diagnosis made in most cases by the referring center. Most of the diagnoses were clinical. Fifty of the 94 patients underwent biopsy when the clinical diagnosis was questionable. Of the 50 patients who underwent biopsy, 18 (36%) received an alternative diagnosis. Analysis was therefore limited to 76 patients, i.e. 44 patients felt to have firm clinical diagnoses plus 32 patients with diagnoses confirmed by biopsy. Mean age was 54.3 years (17-93) and overall gender ratio was 43 F vs. 33 M (56.6% vs. 43.4%). Mean LOS was 15.2 days (1-48) and overall mortality was 23.7% (18/76). Univariate analysis revealed percent body surface area (%BSA) did not show statistically significant association with mortality. Histopathological correlation for diagnosis is not standardized across institutions worldwide. Due to challenges in the diagnosis of SJS/TEN and the high incidence of error in clinical diagnosis, it is recommended that all patients with presumed SJS/TEN receive skin biopsies with H&E and direct immunofluorescence. We propose a diagnostic approach in order to address this need. Lack of association between %BSA and mortality suggests that all biopsy-proven SJS/TEN cases belong in specialty centers due to the unstable nature of the disease and risk for rapid progression.

    Many children and adolescents in the community do not fit the classic Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for Bipolar Disorder, Type I., and bipolar disorder, not otherwise specified (BPNOS) is often the "catch all" diagnosis. Significant research has been conducted to better understand the phenomenology of the spectrum of bipolar disorder; however, there are presently different operational definitions for bipolar disorder, in both clinical and research settings. A recent study, The Course and Outcome of Bipolar Youth (COBY) provided preliminary validation for diagnosing BPNOS. Using these COBY research definitions for BPNOS, we examined the clinical presentation and the prior history of psychotropic medication usage of youth with BPI vs. BPNOS presenting to an outpatient clinic. The initial evaluation consisted of a direct clinical interview with the parent(s) and the patient. Standardized rating scales such as the Young Mania Rating Scale and the Quick Inventory of Depressive Symptoms were used to assess current mood states. The Clinical Global Impressions Scale-Severity was used to assess the overall functioning of bipolar youth. Age, comorbidities, and family histories of 68 bipolar youth in the clinic are similar to what other studies have reported. BPNOS youth have significant functional impairment which is comparable to the BPI youth. Both bipolar groups are equally likely to have similar prior exposure to psychotropic medications. BPNOS is a serious illness the diagnostic guidelines for which are still debatable. Until further clarification of this diagnosis, the COBY definitions for BPNOS can be used in a clinic. The use of stringent criteria for diagnosing the bipolar spectrum disorders allows for careful differential diagnoses of psychiatric illnesses.

    We analyze different examples to show that the so-called generalized Hartman effect is an erroneous presumption. The results obtained for electron tunneling and transmission of electromagnetic waves through superlattices and Bragg gratings show clearly the resonant character of the phase time behavior where a generalized Hartman effect is expected. A reinterpretation of the experimental results in double Bragg gratings is proposed. (author)

    2015-01-01

    Bronchopulmonary Dysplasia (BPD) continues to be an important source of morbidity and mortality in premature neonates. The phenotype of BPD is extremely variable, and diagnosis is a clinical operational definition. A number of clinical and laboratory biomarkers have been proposed for the early identification of infants at higher risk of this disease, to characterize disease activity and severity and for determination of prognosis. Clinical prediction models for BPD have been developed using birth weight, gestational age, indicators of respiratory illness severity, and other clinical variables. Other biomarkers of BPD include those based on imaging of the lungs, lung function measures, and measurements of various analytes in different body fluids (blood, tracheal aspirates, exhaled breath condensates, urine, etc). Novel systems biology ‘omic’ based approaches including but not limited to genomics, proteomics, metabolomics and microbiomics are required for evaluating the multiple interacting cellular and molecular networks that control lung development and injury in BPD. Here we present a critical evaluation of the biomarker approaches studied in the diagnosis of BPD and highlight the future avenues for research in this field. PMID:26593076

  8. Clinical application of positron emission tomography for diagnosis of dementia

    Ishii, Kazunari

    2002-01-01

    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.

    The Department of Veterans Affairs (VA) is amending its adjudication regulations to establish a presumption of service connection for osteoporosis for former Prisoners of War (POWs) who were detained or interned for at least 30 days and whose osteoporosis is at least 10 percent disabling. The amendment implements a decision by the Secretary to establish such a presumption based on scientific studies. VA is additionally amending its adjudication regulations to establish a presumption of service connection for osteoporosis for POWs who were detained or interned for any period of time, have a diagnosis of posttraumatic stress disorder (PTSD), and whose osteoporosis is at least 10 percent disabling. This amendment reflects statutory provisions of the Veterans' Benefits Improvement Act of 2008.

    2017-09-01

    Full Text Available Spontaneous spondylodiscitis is a rare but serious infectious disease which is a combination of an inflammatory process, involving one or more adjacent vertebral bodies (spondylitis, the intervertebral discs (discitis and finally - the neighboring neural structures. In most cases the condition is due to a hematogenous infection and can affect all regions of the spinal cord, but it is usually localized in the lumbar area. The most common clinical symptom is a pronounced, constant and increasing nocturnal paravertebral pain, while consequently different degrees of residual neurological symptoms from nerve roots and/or spinal cord may appear. The disease course is chronic and the lack of specific symptoms often prolongs the time between its debut and the diagnosis. This delay in diagnosis determines its potentially high morbidity and mortality. Treatment is conservative in cases with no residual neurological symptoms and consists of antibiotic therapy and immobilization. Surgical treatment is necessary in patients with neurological deficit, spinal instability or drug resistance.

  11. Systematic Approach toward the Clinical Diagnosis of Functional Dyspepsia

    1999-01-01

    Full Text Available Functional dyspepsia (FD is the most common condition in patients consulting with upper gastrointestinal tract symptoms, resulting in up to 5% of visits to family physicians. By definition, patients with FD have no clinical, biochemical or endoscopic evidence of an organic disease that is likely to explain their symptoms. The process to be used in a structured interview for establishing a clinical diagnosis of FD is presented. The steps are as follows: determine the duration and the course of the disease; characterize the current syndrome and review the alarm symptoms; elicit the patient-perceived dominant symptom and/or condition; and identify the patient’s reason for consulting and address the psychosocial factors. According to the clinical characteristics of the three most frequent causes of dyspepsia (peptic ulcer, gastroesophageal reflux and FD and acknowledging that these conditions may coexist rather than overlap in some patients, an algorithm is suggested for establishing a working diagnosis of FD and indications for investigation, and initiating a management strategy.

  12. Pertussis: clinical and bacteriological diagnosis of six cases

    Directory of Open Access Journals (Sweden)

    Arellano Penagos Mario

    2014-07-01

    Full Text Available ertussis is an endemic disease in our population. Every 3 to 4 years, pertussis has an epidemic pattern even in countries with good health conditions. Antipertussis vaccine first dose is adminis- tered at the age of 2 months; a second and third dose are given at 4 and 6 months of age. This vaccine has an 8 to 10 year protective effect, for which reason it is suggested that pregnant women in the third trimester should be vaccinated in order to prevent pertussis in newborns. It should also be administered to older people to avoid turning them into asymptomatic carriers. Clinic manifestations are easily identifiable due to respiratory symptoms, especially to the particular characteristics of the cough. The diagnosis is supported by the presence of leukocytosis (predominantly lymphocytes and by certain thoracic radiologic findings. The diagnosis is confirmed with a positive culture for Bordetella pertussis or with a polymerase chain reaction (PCR. In a non complicated clinic course macrolides are still the best therapeutic choice. Nonetheless clinic observation is highly recom- mended in order to avoid complications. Redefinition of vaccine programs against Bordetella pertussis in Mexican population is recommended and also to notify the presence of the disease to the corresponding health authorities.

    2016-08-01

    Pituitary stalk interruption syndrome (PSIS) is characterized by a thin or absent pituitary stalk, hypoplasia of the adenohypophysis, and ectopic neurohypophysis. PSIS manifestations include a wide spectrum of clinical phenotypes and pituitary hormone deficiencies of variable degree and timing of onset. In this review, recent advances with respect to the cause of PSIS, clinical characteristics leading to earlier diagnosis, and management are outlined. Diagnosis of PSIS is often delayed probably because clinical findings such as neonatal hypoglycemia, cholestasis, and/or micropenis as well as decreasing growth velocity are not appropriately and timely validated. Recently, molecular defects in various genes have been associated with PSIS albeit in a small number of cases. These findings suggest that PSIS belongs to the spectrum of holoprosencephaly-related defects. Phenotype-genotype discordance and the existence of asymptomatic carriers of a given molecular aberration indicate that penetrance may be modified favorably or unfavorably by the presence of other genetic and/or environmental factors. PSIS constitutes an antenatal anatomical defect. Neonatal hypoglycemia, cholestasis, and/or micropenis with or without growth deficit should raise the possibility of combined pituitary hormone deficiency, a life-threatening condition in cases of coexisting cortisol deficiency. It is important to search for molecular defects in all PSIS cases, as precise identification of the cause is a prerequisite for genetic counseling.

    With increasing numbers of travelers and immunocompromised patients, histoplasmosis, caused by the dimorphic fungus Histoplasma capsulatum, has become a disease of national extent. The clinical spectrum of histoplasmosis is very wide, in terms of disease cadence, onset, distribution, and severity. A multipronged approach is recommended for diagnosis. Manifestations that are always treated include moderate to severe acute pulmonary histoplasmosis, disseminated disease, and histoplasmosis in immunocompromised individuals. Amphotericin B is the drug of choice for moderate to severe and disseminated presentations, whereas itraconazole is appropriate for mild disease and as step-down therapy.

    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: T 7 was 92. 4% reliable, 125 IT 3 resin uptake rate 91. 6% reliable, 131 I thyroid uptake rate in 24 hrs. 89. 4% reliable, serum T 4 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

    Full Text Available Treatment efficacy for children with cancer depends on the diagnosis timeliness since the earlier expert care has been started, the higher likelihood there is to achieve remission. In this regard, a special role belongs to primary care physicians — district pediatricians who should timely recognize the malignant neoplasm and refer the patient to a pediatric oncologist for advice. Wherein, a limited number of primary patients and atypical course of oncological diseases are the causes of a decrease in oncological alertness. This lecture is aimed at a wide range of specialists (pediatricians, radiologists, pathologists and devoted to clinical manifestations and diagnosis of malignant neoplasms in children — hemoblastosis and solid tumours. The suggested algorithms for the examination of patients will allow to make a diagnosis faster and timely initiate expert care in specialized departments. The article is illustrated with unique pictures — images of histological specimens, MRI, and CT of patients with the most neglected cases of malignant neoplasms being the result of diagnostic errors of pediatricians.

    Rat poisoning should be considered in the differential diagnosis of a patient presenting with signs and symptoms of vitamin K deficiency without a more likely explanation. However, confirming this diagnosis may be difficult due to the varying sensitivities of available assays. A 40-year-old Caucasian woman presented to our hospital with chronic abdominal pain, hematuria, and a history of diarrhea of unknown etiology, despite an extensive work-up. Her laboratory evaluation results were consistent with vitamin K deficiency. Because she reported that she had not ingested warfarin, rat poisoning was suspected; however, the results of the first assay were negative. A second specimen was sent to another reference laboratory with a more sensitive assay, and the diagnosis of brodifacoum poisoning was confirmed. The patient was treated with oral vitamin K. If a patient presents with unexplained signs and symptoms of vitamin K deficiency, toxicological evaluation should be performed and repeat testing may be warranted, depending on the sensitivity of the original testing method. © American Society for Clinical Pathology 2018.

    2016-05-01

    For the differential diagnosis between fibrous pleuritis and other malignancies such as lung cancer, multiple immunostaining is essential to diagnose pleural mesothelioma. For cytological diagnosis of pleural effusions, differentiation between mesothelioma cells and reactive mesothelial cells is very difficult. Therefore, histological diagnoses of tumor tissues obtained via biopsy are essential. To diagnose epthelioid mesothelioma, more than 2 positive and negative markers must be consistent with those known for mesothelioma. To diagnose sarcomatoid mesothelioma, keratin is usually positive, differentiating the diagnosis from that for real sarcoma. For surgical treatment for pleural mesothelioma, extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D) are usually performed. The proportion of P/D increases because of the low death rates with surgery and similar survivals. However, a trimodal approach, such as EPP with chemotherapy and radiotherapy, is best for longer survival and expected to be curative. For chemotherapy, only cisplatin (CDDP) combined with pemetrexed (PEM) is effective, and no other agents have been identified for this disease. Nowadays, clinical immunotherapy trials start with phase II study.

    Cytomegalovirus is the most common congenital infection causing serious disease in infants. It is the leading infectious cause of sensorineural hearing loss and neurodevelopmental disability in developed countries. Despite the clinical importance of congenital cytomegalovirus, surveys show there is limited awareness and knowledge in the medical and general community about congenital cytomegalovirus infection. This article reviews the clinical features, global epidemiology, transmission and risk factors for cytomegalovirus infections. It also highlights several major advances made in recent years in the diagnosis and prevention of cytomegalovirus infection during pregnancy. Although research is ongoing, no therapy is currently proven to prevent or treat maternal, fetal or neonatal cytomegalovirus infection. Education of women regarding hygiene measures can help prevent cytomegalovirus infection and are currently the best strategy to prevent congenital cytomegalovirus disease.

    Full Text Available Amyotrophic lateral sclerosis (ALS is a fatal neurodegenerative disease, mainly involving the pyramidal tract, brain stem and spinal cord anterior horn cells, manifests as progressive muscle atrophy, weakness and cramps, as well as cognitive impairment, and may overlap with frontotemporal dementia. ALS is familial in 5% of cases, whose clinical manifestations are similar to sporadic. The diagnosis is made mainly based on clinical manifestations, using internationally recognized consensus standard, after rule out conditions that can mimic ALS. Genetic testing provides a new way to accelerate the diagnostic process for early intervention. Part of the gene mutations are associated with specific phenotypes. According to this, prognosis assessment and genetic counseling are able to carry out.

    Objective: To investigate the MR features of pituitary abscess. Methods: The MR features of 14 eases of pituitary abscess proved by surgical pathology and clinical treatments were analyzed retrospectively. Results: Pre-contrast MR showed hypointense heterogeneous intensity on T 1 WI in 12 cases and iso-hyperintense on T 1 WI in 2 cases, hyperintense on T 2 WI in all cases. Post-gadolinium MR showed the ring-like enhancement around the uneven edge of abscess and the surrounding enhanced meninges connecting to the focus. The normal pituitary could not be identified in all 14 cases. The MR specific findings include the fluid-fluid level, nodule on the edge and the enhanced patchy shadow. Conclusions: The pituitary abscess has specific findings on MR examination, which can be used to combine with clinical symptoms to achieve the diagnosis before operation, so that the cases could be treated with antibiotic without operation.

    2011-01-01

    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)

    Full Text Available Introduction. The small renal masses (SRMs have increased over the past two decades due to more liberal use of imaging techniques. 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.

    Zika virus (ZIKV) is an arbovirus previously believed to cause only a mild and self-limiting illness. Recently, it has emerged as a new public health threat that caused a large outbreak in French Polynesia in 2013-2014 and since 2015 an explosive outbreak in Brazil, with an increase in severe congenital malformations (microcephaly) and neurological complications, mainly Guillain-Barré syndrome (GBS). Since then, it has spread through the Americas. On 1 February 2016, the WHO declared the ZIKV epidemic in Brazil a Public Health Emergency of International Concern. We reviewed the epidemiology of ZIKV infection, clinical presentations and diagnosis. We highlighted the clinical features and nonvector borne transmission of the virus. Association between ZIKV infection and severe foetal outcomes, including microcephaly and other birth defects; increased rate of GBS and other neurological complications due to the ongoing ZIKV outbreak; increased evidence to date of ZIKV being the only arbovirus linked to sexual transmission; the challenge of ZIKV diagnosis; and the need for a specific point-of care test in epidemic scenarios. The findings illustrate the emergence of a viral disease with the identification of new associated disorders, new modes of transmission, including maternal-foetal and sexual transmission.

    Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by the reactivation of a ubiquitous polyomavirus JC (JCV). PML was for many years a rare disease occurring only in patients with underlying severe impaired immunity. Over the past three decades, the incidence of PML has significantly increased related to the AIDS (acquired immunodeficiency syndrome) pandemic and, more recently, to the growing use of immunosuppressive drugs. The clinical presentation of PML is variable with neurological symptoms corresponding to affected cerebral areas. Usually, the clinical outcome of patients with PML is poor with an inexorable progression to death within 6 months of symptom onset. Although PML usually requires a brain biopsy or autopsy for confirmation, radiological imaging and a demonstration of JCV-DNA in the CSF (cerebrospinal fluid) provide supportive evidence for the diagnosis. Although there is no proven effective therapy for PML, patients with HIV (human immunodeficeincy virus)-related PML may benefit significantly from HAART (highly active antiretroviral therapy). In this article the author reviews the epidemiology, especially in Japan, current challenges in the diagnosis and the treatment guidelines of patients with PML based on recent advances in the understanding of the JC virus biology.

    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.

    Full Text Available Introduction & Objective: β- hemolytic group A streptococcus is the most common cause of acute bacterial pharyngitis in children.Due to the high incidence of this disease and it's difficult diagnosis , we decided to compare clinical scoring and throat cultures for diagnosis of streptococcal pharyngitis. Materials & Methods: This cross-sectional analytic study was done on 3-16 year old patients reffered to pediatric clinic with complaint of sore throat. After taking history and physical examination, scoring was done based on clinical findings.The patients with chronic disease or those who received antibiotics or other drugs were eliminated from the study. Analysis was performed using SPSS. Score for each patient was calculated and compared with the result of throat cultures. Sensitivity, specificity, positive and negative predictive values for each clinical finding were determined. Results: 315 patients out of 350 patients with complaint of sore throat referred to the clinic had fever of whom 51.1% had positive throat culture with 51.1% sensitivity and 77% specifity (p<0.01. 127 patients had pharyngeal petechia of whom 67% had positive throat culture with 66.9% sensitivity and 73.5% specifity (p<0.002. 105 children had pharyngeal exudates of whom 65.7% had positive throat culture with 65.7% sensitivity and 58.3% specifity (p<0.001.

  10. Diagnosis of depression in children and adolescents. Clinical pointers to a difficult diagnosis.

    Science.gov (United States)

    2010-04-01

    It is now accepted that depression can also affect children and adolescents, but its diagnosis is not straightforward. We examined review articles published on this subject over the last 15 years by large specialist groups and multidisciplinary teams. Most studies of symptoms of psychological distress and depression in children are mainly based on clinical experience of specialists and therefore provide only modest evidence. Isolated, transient unhappiness is not in itself a symptom of depression, but recurrent and persistent mood disorders constitute important warning signs. A French consensus jury recommended attentive listening to potentially depressed children, and those closest to them, focusing on phrases that might reflect a loss of interest, enjoyment, self-esteem and self-confidence; feelings of guilt, shame, loss of affection and hope; and morbid or suicidal ideas. British clinical practice guidelines recommend evaluating the severity of a depressive episode on the basis of the type and number of symptoms, and the family context. Scores designed to diagnose depression and assess its severity are controversial. In practice, diagnosis of depression in children and adolescents with persistent psychological distress is not based on a simple list of symptoms. In difficult cases, it is better to adopt a multidisciplinary approach in order to gauge severity and to determine the most appropriate treatment, which, in most cases, does not involve the use of drugs.

    Full Text Available Dental pulp represents a specialized connective tissue enclosed by dentin and enamel, the most highly mineralized tissues of the body. Consequently, the direct examination as well as pathological evaluation of dental pulp is difficult. Within this anatomical context, our study aimed to evaluate the correlation between dental pulp lesions and clinical diagnosis. Pulpectomies were performed for 54 patients with acute and chronic irreversible pulpitides and for 5 patients (control group with orthodontic extractions. The morphological features were semiquantitatively assessed by specific score values. The clinical and morphological correspondence was noted for 35 cases (68.62%, whereas inconsistency was recorded for 16 cases (31.38%. The results of the statistical analysis revealed the correlations between clinically and pathologically diagnosed acute/chronic pulpitides. No significant differences were established between the score values for inflammatory infiltrate intensity, collagen depositions, calcifications and necrosis, and acute, respectively chronic pulpitides. We also obtained significant differences between acute pulpitides and inflammatory infiltrate and calcifications and between chronic pulpitides and inflammatory infiltrate, collagen deposition, and calcifications. On the basis of the predominant pathological aspects, namely, acute and chronic pulpitis, we consider that the classification schemes can be simplified by adequately reducing the number of clinical entities.

    The updated international consensus criteria for definite antiphospholipid syndrome (APS) are useful for scientific clinical studies. However, there remains a need for diagnostic criteria for routine clinical use. We audited the results of routine antiphospholipid antibodies (aPLs) in a cohort of 193 consecutive patients with aPL positivity-based testing for lupus anticoagulant (LA), IgG and IgM anticardiolipin (aCL) and anti-ß2glycoprotein-1 antibodies (aß2GPI). Medium/high-titre aCL/aβ2GPI was defined as >99th percentile. Low-titre aCL/aβ2GPI positivity (>95th < 99th percentile) was considered positive for obstetric but not for thrombotic APS. One hundred of the 145 patients fulfilled both clinical and laboratory criteria for definite APS. Twenty-six women with purely obstetric APS had persistent low-titre aCL and/or aβ2GPI. With the inclusion of these patients, 126 of the 145 patients were considered to have APS. Sixty-seven out of 126 patients were LA-negative, of whom 12 had aCL only, 37 had aβ2GPI only and 18 positive were for both. The omission of aCL or aβ2GPI testing from investigation of APS would have led to a failure to diagnose APS in 9.5% and 29.4% of patients, respectively. Our data suggest that LA, aCL and aβ2GPI testing are all required for the accurate diagnosis of APS and that low-titre antibodies should be included in the diagnosis of obstetric APS. PMID:22988029

    Flail arm syndrome (FAS) is a variant of motor neuron disease which is characterized by progressive, predominantly proximal weakness and atrophy of the upper limbs (UL). Because of its heterogeneous presentation and its relatively slow progression, differential diagnosis may be difficult particularly in the early stages of the disease. The aim of this study was to investigate typical clinical features of FAS with special regard to initial symptoms and differences to classical Charcot type amyotrophic lateral sclerosis (ALS). We retrospectively evaluated the clinical features of 42 FAS patients who were seen in the outpatient clinics of 4 German centers between 2000 and 2010 and compared them to 146 sex-matched control patients with classical spinal-onset ALS. FAS patients were younger (54.7 ± 9.3 versus 59.4 ± 12.2 years), male patients were predominantly affected (3.8:1 versus 1.9:1), and FAS patients showed a prolonged survival (53 versus 33 months) compared to classical ALS patients. The share of patients with initial misdiagnoses was 54.8% and led to ineffective therapy with immunoglobulins in 26%. Initial symptoms were most frequently present either in distal muscles only or in both proximal and distal muscle groups combined (76%) and showed an asymmetric distribution pattern in the majority of cases (76%). Although all patients developed symmetric and predominantly proximal UL weakness and atrophy during the course of their disease, we found that most patients initially showed asymmetric and predominantly distal distribution of symptoms. This may contribute to difficulties in differential diagnosis and to ineffective treatment regimes.

    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.

  16. 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.

    Endoscopy is essential for the diagnosis and treatment of cancers derived from the larynx. However, a laryngoscope with conventional white light (CWL) has technical limitations in detecting small or superficial lesions on the mucosa. Narrow band imaging especially combined with magnifying endoscopy (ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity. A total of 3675 patients who have come to the outpatient clinic and complained of inspiratory stridor, dyspnea, phonation problems or foreign body sensation, were enrolled in this study. We describe the glottic conditions of the patients. All 3675 patients underwent laryngoscopy equipped with conventional white light (CWL) and NBI system. 1149 patients received a biopsy process. And 1153 lesions were classified into different groups according to their histopathological results. Among all the 1149 patients, 346 patients (312 males, 34 females; mean age 62.2±10.5 years) were suspected of having a total of 347 precancerous or cancerous (T1 or T2 without lymphnode involvement) lesions of the larynx under the CWL. Thus, we expected to attain a complete vision of what laryngeal lesions look like under the NBI view of a laryngoscope. The aim was to develop a complete description list of each laryngeal conditions (e.g. polyps, papilloma, leukoplakia, etc.), which can serve as a criteria for further laryngoscopic examinations and diagnosis.

    To evaluate the feasibility of antenatal sonographic diagnosis of umbilical arterial atresia and its clinical significance. Data of 5 cases with umbilical arterial atresia diagnosed in our hospital were studied retrospectively. The antenatal ultrasonogram of umbilical arterial atresia was obtain, and the pathological examination of umbilical cords and the prognosis of neonates were analyzed. Among 5 cases with umbilical arterial atresia in this group, 1 case with double umbilical arterial atresia was found with dead fetus in uterus, and the rest 4 cases with single umbilical arterial atresia were found with survival fetuses. In the latter 4 cases with live fetus, once umbilical arterial atresia was diagnosed, cesarean section was performed to terminate pregnancy, and the 4 fetus were all healthy. The chromosome karyotypes and S/D value of umbilical arteries were showed normal in all 5 cases. Accurate antenatal diagnosis can be made according to the specific ultrasonogram of umbilical arterial atresia. Instant intervention should be performed upon observing umbilical arterial atresia with live fetus, so as to avoid dead fetus as much as possible.

    In 63 patients echography of thyroid was performed additionally to case history, palpation, scintigraphy and hormone tests for evaluating clinical significance of this method. The benefit of this technique is rapid measurement of thyroid size, demonstration of nodules in palpable diffuse goiters and differentiating of solid or cystic nodules of the thyroid. For diagnosis of autonomous areas in the thyroid scintigrahy remains the method of choice. Also there is no correlation of ultrasound findings and thyroid function. In routine diagnostic procedure of thyroid disease echography may replace scintigraphy only in diffuse goiter and if radionuclide imaging is not possible. Nevertheless ultrasonic evaluation of the thyroid is an important additional method in diagnostic of thyroid diseases. (Author)

    ABSTRACT: Superior labral anterior posterior (SLAP) tears are an abnormality of the superior labrum usually centered on the attachment of the long head of the biceps tendon. Tears are commonly caused by repetitive overhead motion or fall on an outstretched arm. SLAP lesions can lead to shoulder pain and instability. Clinical diagnosis is difficult thus imaging plays a key diagnostic role. The normal anatomic variability of the capsulolabral complex can make SLAP lesions a diagnostic challenge. Concurrent shoulder injuries are often present including rotator cuff tears, cystic changes or marrow edema in the humeral head, capsular laxity, Hill-Sachs or Bankart lesion. The relevant anatomy, capsulolabral anatomic variants, primary and secondary findings of SLAP tears including MR arthrography findings, types of SLAP lesions and a practical approach to labral lesions are reviewed.

    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)

    Skeletal muscle tissue has the largest mass in the human body, accounting for 45% of the total weight. Muscle injuries can be caused by bruising, stretching or laceration. The current classification divides such injuries into mild, moderate and severe. The signs and symptoms of grade I lesions are edema and discomfort; grade II, loss of function, gaps and possible ecchymosis; and grade III, complete rupture, severe pain and extensive hematoma. The diagnosis can be confirmed by: ultrasound, which is dynamic and cheap, but examiner dependent; and tomography or magnetic resonance, which gives better anatomical definition, but is static. Initial phase of the treatment can be summarized as the “PRICE” protocol. NSAIDs, ultrasound therapy, strengthening and stretching after the initial phase and range of motion without pain are used in clinical treatment. On the other hand, surgery has precise indications: hematoma drainage and muscle-tendon reinsertion and reinforcement. PMID:27047816

    Coarctation of the aorta (CoA ) is a well-known congenital heart disease (CHD) , which is often associated with several other cardiac and vascular anomalies, such as bicuspid aortic valve (BAV), ventricular septal defect, patent ductus arteriosus and aortic arch hypoplasia. Despite echocardiographic screening, prenatal diagnosis of C o A remains difficult. Most patients with CoA present in infancy with absent, delayed or reduced femoral pulses, a supine arm-leg blood pressure gradient (> 20 mm Hg), or a murmur due to rapid blood flow across the CoA or associated lesions (BAV). Transthoracic echocardiography is the primary imaging modality for suspected CoA. However, cardiac magnetic resonance imaging is the preferred advanced imaging modality for non-invasive diagnosis and follow-up of CoA. Adequate and timely diagnosis of CoA is crucial for good prognosis, as early treatment is associated with lower risks of long-term morbidity and mortality. Numerous surgical and transcatheter treatment strategies have been reported for CoA. Surgical resection is the treatment of choice in neonates, infants and young children. In older children (> 25 kg) and adults, transcatheter treatment is the treatment of choice. In the current era, patients with CoA continue to have a reduced life expectancy and an increased risk of cardiovascular sequelae later in life, despite adequate relief of the aortic stenosis. Intensive and adequate follow-up of the left ventricular function, valvular function, blood pressure and the anatomy of the heart and the aorta are , therefore, critical in the management of CoA. This review provides an overview of the current state-of-the-art clinical diagnosis, diagnostic imaging algori thms, treatment and follow-up of patients with CoA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Bordetella pertussis (BP) is a common cause of prolonged cough. Our objective was to perform an updated systematic review of the clinical diagnosis of BP without restriction by patient age. We identified prospective cohort studies of patients with cough or suspected pertussis and assessed study quality using QUADAS-2. We performed bivariate meta-analysis to calculate summary estimates of accuracy and created summary receiver operating characteristic curves to explore heterogeneity by vaccination status and age. Of 381 studies initially identified, 22 met our inclusion criteria, of which 14 had a low risk of bias. The overall clinical impression was the most accurate predictor of BP (positive likelihood ratio [LR+], 3.3; negative likelihood ratio [LR-], 0.63). The presence of whooping cough (LR+, 2.1) and posttussive vomiting (LR+, 1.7) somewhat increased the likelihood of BP, whereas the absence of paroxysmal cough (LR-, 0.58) and the absence of sputum (LR-, 0.63) decreased it. Whooping cough and posttussive vomiting have lower sensitivity in adults. Clinical criteria defined by the Centers for Disease Control and Prevention were sensitive (0.90) but nonspecific. Typical signs and symptoms of BP may be more sensitive but less specific in vaccinated patients. The clinician's overall impression was the most accurate way to determine the likelihood of BP infection when a patient initially presented. Clinical decision rules that combine signs, symptoms, and point-of-care tests have not yet been developed or validated. © Copyright 2017 by the American Board of Family Medicine.

    Sixty-four dogs were treated with single-agent doxorubicin (DOX) for presumptive cardiac hemangiosarcoma (cHSA). The objective response rate (CR + PR) was 41%, and the biologic response rate (CR + PR + SD), or clinical benefit, was 68%. The median progression-free survival (PFS) for treated dogs was 66 days. The median survival time (MST) for this group was 116 days and was significantly improved compared to a MST of 12 days for untreated control dogs (P = 0.0001). Biologic response was significantly associated with improved PFS (P < 0.0001) and OS (P < 0.0001). Univariate analysis identified larger tumour size as a variable negatively associated with PFS. The high rate of clinical benefit and improved MST suggest that DOX has activity in canine cHSA. © 2014 John Wiley & Sons Ltd.

    Restless legs syndrome (RLS), a common neurological sensorimotor disorder in western countries, has gained more and more attention in Asian countries. The prevalence of RLS is higher in older people and females. RLS is most commonly related to iron deficiency, pregnancy and uremia. The RLS symptoms show a significant circadian rhythm and a close relationship to periodic limb movements (PLMs) in clinical observations, while the pathophysiological pathways are still unknown. The diagnostic criteria have been revised in 2012 to improve the validity of RLS diagnosis. Recent studies have suggested an important role of iron decrease of brain in RLS pathophysiology. Dopaminergic (DA) system dysfunction in A11 cell groups has been recognized long ago from clinical treatment and autopsy. Nowadays, it is believed that iron dysfunction can affect DA system from different pathways and opioids have a protective effect on DA system. Several susceptible single nucleotide polymorphisms such as BTBD9 and MEIS1, which are thought to be involved in embryonic neuronal development, have been reported to be associated with RLS. Several pharmacological and non-pharmacological treatment are discussed in this review. First-line treatments of RLS include DA agents and α2δ agonists. Augmentation is very common in long-term treatment of RLS which makes prevention and management of augmentation very important for RLS patients. A combination of different types of medication is effective in preventing and treating augmentation. The knowledge on RLS is still limited, the pathophysiology and better management of RLS remain to be discovered. PMID:28626420

    Breast cancer is the most common malignancy affecting women worldwide. Women have a 1 in 8 lifetime risk of breast cancer. Breast conservation therapy (BCT) is the most common method of definitive treatment. Patients who previously have had to undergo mastectomy may be now eligible for BCT or a multitude of options for reconstruction, either immediate or delayed. Surveillance imaging after a breast cancer diagnosis is important because there is an increased risk of recurrence developing in patients, and early detection has been shown to improve survival. There is currently no consensus on a protocol for imaging the postoperative breast. In patients who have undergone mastectomy, detection of recurrence has mostly been via clinical symptoms and physical exam, often at a later stage. New imaging modalities, such as magnetic resonance imaging (MRI), ultrasound (US), and positron emission mammography (PEM) are changing the way we image the postsurgical breast. MRI, coupled with physical exam and mammography, approaches 100% sensitivity and high specificity for the identification of recurrent disease. We present a review of major academic institutions' imaging protocols and discuss the advantages of including MRI in traditional mammographic and clinical exams.

    Objective: Comparison of real time reverse transcriptase polymerase chain reaction (RTPCR) and immunoglobulin M (IgM) capture enzyme linked immunosorbent assay (ELISA) for diagnosis of dengue virus infection in first week of illness in clinically suspected patients of dengue fever. Study Design: Cross sectional study. Place and Duration of Study: Department of haematology, Armed Forces Institute of Pathology (AFIP) Rawalpindi from Jan 2013 to Nov 2013. Material and Methods: A cross sectional study including 68 clinically suspected patients of dengue fever according to the World Health Organization (WHO) criteria. IgM capture ELISA and RT PCR for dengue virus ribonucleic acid (RNA) was performed on samples collected from patients having fever for 1 to 7 days. These were divided into two groups. Patients in group 1 presented with fever of 4 days or less, patients in group 2 had fever of 5 to 7 days duration. Results: In group 1, 72 percent of the patients were positive by RT PCR while 31 percent were positive by IgM capture ELISA. In group 2, 43 percent of the patients were positive by RT PCR while 97 percent were positive by ELISA. Conclusion: RT PCR can be used for early detection of dengue virus infection in the first few days of fever while IgM ELISA is diagnostic afterwards. (author)

    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.

    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 cm 2 . 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.)

    Microscopic detection and morphological identification of parasites from clinical specimens are the gold standards for the laboratory diagnosis of parasitic infections. The limitations of such diagnostic assays include insufficient sensitivity and operator dependence. Immunoassays for parasitic antigens are not available for most parasitic infections and have not significantly improved the sensitivity of laboratory detection. Advances in molecular detection by nucleic acid amplification may improve the detection in asymptomatic infections with low parasitic burden. Rapidly accumulating genomic data on parasites allow the design of polymerase chain reaction (PCR) primers directed towards multi-copy gene targets, such as the ribosomal and mitochondrial genes, which further improve the sensitivity. Parasitic cell or its free circulating parasitic DNA can be shed from parasites into blood and excreta which may allow its detection without the whole parasite being present within the portion of clinical sample used for DNA extraction. Multiplex nucleic acid amplification technology allows the simultaneous detection of many parasitic species within a single clinical specimen. In addition to improved sensitivity, nucleic acid amplification with sequencing can help to differentiate different parasitic species at different stages with similar morphology, detect and speciate parasites from fixed histopathological sections and identify anti-parasitic drug resistance. The use of consensus primer and PCR sequencing may even help to identify novel parasitic species. The key limitation of molecular detection is the technological expertise and expense which are usually lacking in the field setting at highly endemic areas. However, such tests can be useful for screening important parasitic infections in asymptomatic patients, donors or recipients coming from endemic areas in the settings of transfusion service or tertiary institutions with transplantation service. Such tests can also

    Overtraining results from an imbalance between training load-induced fatigue and organism's recovery abilities. Its etiology is complex and to date there is no useful clinical diagnostic tool. The purpose of this review is to discuss the blood chemistry parameters potentially useful for diagnosing overtraining in athletes. Chronic alterations of the myocyte structure may cause high plasma concentration increases of myoglobin, troponin I and creatine kinase enzyme, resulting in chemical and/or mechanical aggression. Monitoring reactive oxygen species' activity appears to be a good tool for evaluation of the metabolic stress level experienced by skeletal muscles. In energetic metabolism, a succession of chronic glycogen depletions might change the use of amino acids and lipids, inducing transient but severe hypoglycemia during exercise. A higher oxidation of circulating glutamine might cause immunosuppression (lower reactivity to inflammations and cellular traumatisms), inhibiting alarm signals during acute training. A higher branched-chain amino acid oxidation might favor free tryptophan's entry into the cerebral area, enhancing serotonin synthesis. As a consequence, asthenia and a loss of sensitivity to muscular and tendon traumatism might appear. Exercise anemia might also be a worsening factor of the physiological situation of the tired athlete, inducing predisposition to overtraining by the lower inflammation reactivity of depleted hepatic and muscular proteins. Early diagnosis of overtraining diagnosis may be established only from a battery of analyses, which should include the whole of the potential parameters. These remain unpredictable and do not allow systematic determination of new cases. Only a longitudinal study of the physiological situation appears to allow the necessary conditions for detecting overtraining in the early stages of its process for each subject.

    2009-01-01

    Full Text Available Current guidelines recommend that all fever episodes in African children be treated presumptively with antimalarial drugs. But declining malarial transmission in parts of sub-Saharan Africa, declining proportions of fevers due to malaria, and the availability of rapid diagnostic tests mean it may be time for this policy to change. This debate examines whether enough evidence exists to support abandoning presumptive treatment and whether African health systems have the capacity to support a shift toward laboratory-confirmed rather than presumptive diagnosis and treatment of malaria in children under five.

    2008-01-01

    Full Text Available Cerebral venous thrombosis (CVT has a wide spectrum of clinical manifestations that may mimic many other neurological disorders and lead to misdiagnoses. Headache is the most common symptom and may be associated with other symptoms or remain isolated. The other frequent manifestations are focal neurological deficits and diffuse encephalopathies with seizures. The key to the diagnosis is the imaging of the occluded vessel or of the intravascular thrombus, by a combination of magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Causes and risk factors include medical, surgical and obstetrical causes of deep vein thrombosis, genetic and acquired prothrombotic disorders, cancer and hematological disorders, inflammatory systemic disorders, pregnancy and puerperium, infections and local causes such as tumors, arteriovenous malformations, trauma, central nervous system infections and local infections. The breakdown of causes differs in different parts of the world. A meta-analysis of the most recent prospectively collected series showed an overall 15% case-fatality or dependency rate. Heparin therapy is the standard therapy at the acute stage, followed by 3-6 months of oral anticoagulation. Patients with isolated intracranial hypertension may require a lumbar puncture to remove cerebrospinal fluid before starting heparin when they develop a papilloedema that may threaten the visual acuity or decompressive hemicraniectomy. Patients who develop seizures should receive antiepileptic drugs. Cerebral venous thrombosis - even pregnancy-related - should not contraindicate future pregnancies. The efficacy and safety of local thrombolysis and decompressive hemicraniectomy should be tested

    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 scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011. The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies. The clinical diagnosis of FMS can be established by the American College of Rheumatology (ACR) 1990 classification criteria (with tender point examination), by the modified preliminary diagnostic ACR 2010 criteria or by the diagnostic criteria of the German interdisciplinary guideline (AWMF) on FMS.

    In the analysis of the characteristics of a pleasant smile, a gummy smile has negative components, which most affect the esthetics of non-verbal communication. For this purpose a proposed classification based upon etiopathogenetic criteria as useful indications for a therapeutical approach is given. The nature of a high smile line can be: dento-gingival, connected to an abnormal dental eruption, which is revealed by a short clinic crown; muscular, caused by an hyperactivity of the elevator muscle of the upper lip; dento-alveolar (skeletal), due to an excessive protuberance or vertical growth of the jawbone (maxillary); lastly, a mixed nature, in the presence of more than one of the above described factors The diagnosis of gummy smile must be precocious and based, with reference to specific parameters, upon a careful analysis of the etiopathogenetic factors and the degree of seriousness of the alteration. A correct treatment plan must contemplate the possibility of an orthognatodontic, orthopedic and/or surgical therapeutic resolution considering the seriousness and complexity of the gums exposures (high smile line) in connection with the age of the subject.

    To update the Spanish Society of Neurology's guidelines for subarachnoid haemorrhage diagnosis and treatment. A review and analysis of the existing literature. Recommendations are given based on the level of evidence for each study reviewed. The most common cause of spontaneous subarachnoid haemorrhage (SAH) is cerebral aneurysm rupture. Its estimated incidence in Spain is 9/100 000 inhabitants/year with a relative frequency of approximately 5% of all strokes. Hypertension and smoking are the main risk factors. Stroke patients require treatment in a specialised centre. Admission to a stroke unit should be considered for SAH patients whose initial clinical condition is good (Grades I or II on the Hunt and Hess scale). We recommend early exclusion of aneurysms from the circulation. The diagnostic study of choice for SAH is brain CT (computed tomography) without contrast. If the test is negative and SAH is still suspected, a lumbar puncture should then be performed. The diagnostic tests recommended in order to determine the source of the haemorrhage are MRI (magnetic resonance imaging) and angiography. Doppler ultrasonography studies are very useful for diagnosing and monitoring vasospasm. Nimodipine is recommended for preventing delayed cerebral ischaemia. Blood pressure treatment and neurovascular intervention may be considered in treating refractory vasospasm. SAH is a severe and complex disease which must be managed in specialised centres by professionals with ample experience in relevant diagnostic and therapeutic processes.

    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? (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.

    Kratom ( Mitragyna speciosa ) is a tropical tree with a long history of traditional use in parts of Africa and Southeast Asia. Kratom is also known as Thom, Thang, and Biak. Its leaves and the teas brewed from them have long been used by people in that region to manage pain and opioid withdrawal and to stave off fatigue. Kratom is actually consumed throughout the world for its stimulant effects and as an opioid substitute (in form of tea, chewed, smoked, or ingested in capsules). Some case reports have associated kratom exposure with psychosis, seizures, intrahepatic cholestasis, other medical conditions, and deaths. The clinical manifestations of kratom effects are not well defined and the clinical studies are limited. Data research suggest that both stimulant and sedative dose-dependent effects do exist, in addition to antinociceptive, antidepressant activity, anxiolytic-like effects, and anorectic effects, but a growing concern for the drug's effects and safety of use has resulted in national and international attention primarily due to an increase in hospital visits and deaths in several countries that are believed to have been caused by extracts of the plant. There is a dearth of double blind controlled studies. In this study, we aim to use existing literature to clarify both benefits and risks of kratom as well as its diagnosis evaluation as kratom misuse is an emerging trend in the Western world. Literature review using databases such as Embase, Medline, PubMed, Cochrane Library, and Mendeley from 2007 to 2017 were evaluated by all authors to analyze current state on benefits, risks, and diagnosis evaluation of kratom ( M. speciosa ). Data analysis suggested that kratom possesses some benefits such as stimulant and sedative effects as wells as antinociceptive effects. It seems to inhibit pro-inflammatory mediator release and vascular permeability and can enhance immunity. In addition, it may be an antidepressant and anorectic. However, kratom can cause

    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

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

    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.

    three-year-old male Boxer dog had hyperesthesia, symmetrical epaxial, gluteal and hind limb muscular atrophy and rear limb ataxia. Neurological deficits included decreased conscious proprioception of the left hind limb, decreased withdrawal and increased patellar reflexes of both hind limbs. The dog had a urinary tract infection with positive culture for Staphylococcus intermedius. On survey radiography of the lumbosacral spine there was active bone proliferation spanning the L7 S1 intervertebral disc space with an epidural filling defect at the ventral aspect of the vertebral canal on epidurography. On magnetic resonance imaging (MRI), findings were similar to those described for human diskospondylitis including altered signal intensity and nonuniform contrast enhancement of the L7-S1 intervertebral disc, adjacent vertebral end plates and epidural and sublumbar soft tissues. Although skeletal radiography is usually sufficient to reach a diagnosis of discospondylitis, MRI of this patient made it possible to reach a presumptive diagnosis of discospondylitis prior to development of definitive radiographic abnormalities

    Vaginitis may be diagnosed as bacterial vaginosis, vulvovaginal candidiasis, trichomoniasis, or coinfection. A new molecular test assays the vaginal microbiome and organisms that cause three common infections. The objective of the trial was to evaluate the clinical accuracy of the investigational test for vaginal swabs collected by patients (self) or clinicians. The primary and secondary outcomes were to compare the investigational test with reference methods for the three most common causes of vaginitis and compare clinician-collected with self-collected swabs. We conducted a cross-sectional study in which women with symptoms of vaginitis were recruited at ten clinical centers and consented to the investigation between May and September 2015. The woman collected a vaginal swab, sheathed, and then handed it to the clinician. These swabs were to evaluate how self-collected swabs compared with clinician-collected swabs. The clinician collected an investigational test swab and reference test swabs. From 1,740 symptomatic patients, clinician-collected and self-collected vaginal swabs were evaluated by the molecular test and six tests. The reference methods for bacterial vaginosis were Nugent's score and Amsel's criteria for intermediate Nugent results. The reference methods for Candida infection were isolation of any potential Candida microorganisms from inoculation of two culture media: chromogenic and Sabouraud agar and sequencing. The reference methods for trichomoniasis were wet mount and culture. For clinician-collected swabs, by reference methods, bacterial vaginosis was diagnosed in 56.5%, vaginal candidiasis in 32.8%, trichomoniasis in 8%, and none of the three infections in 24% with a coinfection rate of 20%. The investigational test sensitivity was 90.5% (95% confidence interval [CI] 88.3-92.2%) and specificity was 85.8% (95% CI 83.0-88.3%) for bacterial vaginosis. The investigational test sensitivity was 90.9% (95% CI 88.1-93.1%) and specificity was 94

    We aim to report the quality of accuracy studies investigating the utility of [ 18 F]fluorodeoxyglucose (FDG)-PET in supporting the diagnosis of prodromal Alzheimer's Disease (AD), frontotemporal lobar degeneration (FTLD) and prodromal dementia with Lewy bodies (DLB) in mild cognitive impairment (MCI) subjects, and the corresponding recommendations made by a panel of experts. Seven panellist, four from the European Association of Nuclear Medicine, and three from the European Academy of Neurology, produced recommendations taking into consideration the incremental value of FDG-PET, as added on clinical-neuropsychological examination, to ascertain the aetiology of MCI (AD, FTLD or DLB). A literature search using harmonized population, intervention, comparison, and outcome (PICO) strings was performed, and an evidence assessment consistent with the European Federation of Neurological Societies guidance was provided. The consensual recommendation was achieved based on Delphi rounds. Fifty-four papers reported the comparison of interest. The selected papers allowed the identification of FDG patterns that characterized MCI due to AD, FTLD and DLB. While clinical outcome studies supporting the diagnosis of MCI due to AD showed varying accuracies (ranging from 58 to 100%) and varying areas under the receiver-operator characteristic curves (0.66 to 0.97), no respective data were identified for MCI due to FTLD or for MCI due to DLB. However, the high negative predictive value of FDG-PET and the existence of different disease-specific patterns of hypometabolism support the consensus recommendations for the clinical use of this imaging technique in MCI subjects. FDG-PET has clinical utility on a fair level of evidence in detecting MCI due to AD. Although promising also in detecting MCI due to FTLD and MCI due to DLB, more research is needed to ultimately judge the clinical utility of FDG-PET in these entities.

    Encephalitis is a severe inflammatory disorder of the brain with many possible causes and a complex differential diagnosis. Advances in autoimmune encephalitis research in the past 10 years have led to the identification of new syndromes and biomarkers that have transformed the diagnostic approach to these disorders. However, existing criteria for autoimmune encephalitis are too reliant on antibody testing and response to immunotherapy, which might delay the diagnosis. We reviewed the literature and gathered the experience of a team of experts with the aims of developing a practical, syndrome-based diagnostic approach to autoimmune encephalitis and providing guidelines to navigate through the differential diagnosis. Because autoantibody test results and response to therapy are not available at disease onset, we based the initial diagnostic approach on neurological assessment and conventional tests that are accessible to most clinicians. Through logical differential diagnosis, levels of evidence for autoimmune encephalitis (possible, probable, or definite) are achieved, which can lead to prompt immunotherapy. PMID:26906964

  5. Cushing's syndrome: from physiological principles to diagnosis and clinical care

    Raff, Hershel; Carroll, Ty

    2015-01-01

    The physiological control of cortisol synthesis in the adrenal cortex involves stimulation of adrenocorticotrophic hormone (ACTH) by hypothalamic corticotrophin-releasing hormone (CRH) and then stimulation of the adrenal by ACTH. The control loop of the hypothalamic–pituitary–adrenal (HPA) axis is closed by negative feedback of cortisol on the hypothalamus and pituitary. Understanding this system is required to master the diagnosis, differential diagnosis and treatment of endogenous hypercortisolism – Cushing's syndrome. Endogenous Cushing's syndrome is caused either by excess ACTH secretion or by autonomous cortisol release from the adrenal cortex. Diagnosis of cortisol excess exploits three physiological principles: failure to achieve the normal nadir in the cortisol diurnal rhythm, loss of sensitivity of ACTH-secreting tumours to cortisol negative feedback, and increased excretion of free cortisol in the urine. Differentiating a pituitary source of excess ACTH (Cushing's disease) from an ectopic source is accomplished by imaging the pituitary and sampling for ACTH in the venous drainage of the pituitary. With surgical removal of ACTH or cortisol-secreting tumours, secondary adrenal insufficiency ensues because of the prior suppression of the HPA axis by glucocorticoid negative feedback. Medical therapy is targeted to the anatomical location of the dysregulated component of the HPA axis. Future research will focus on new diagnostics and treatments of Cushing's syndrome. These are elegant examples of translational research: understanding basic physiology informs the development of new approaches to diagnosis and treatment. Appreciating pathophysiology generates new areas for inquiry of basic physiological and biochemical mechanisms. PMID:25480800

    Full Text Available Xpert MTB/RIF is approved for use in tuberculosis (TB and rifampicin-resistance diagnosis. However, data are limited on the impact of Xpert under routine conditions in settings with high TB burden.A pragmatic prospective cluster-randomised trial of Xpert for all individuals with presumptive (symptomatic TB compared to the routine diagnostic algorithm of sputum microscopy and limited use of culture was conducted in a large TB/HIV primary care clinic. The primary outcome was the proportion of bacteriologically confirmed TB cases not initiating TB treatment by 3 mo after presentation. Secondary outcomes included time to TB treatment and mortality. Unblinded randomisation occurred on a weekly basis. Xpert and smear microscopy were performed on site. Analysis was both by intention to treat (ITT and per protocol.

    Foot posture involves the integration of sensory information from the periphery of the body. This information generates precise changes through fine adjustments that compensate for the continuous, spontaneous sway of the body in the standing position. Orthopedic insoles are one of the therapeutic resources indicated for assisting in this process. Evaluation of these podal influences, by clinical examination and/or the assistance of baropodometry becomes crucial. Thus, the aim of the present study was determine the combination of the components of orthopedic insoles using two different evaluation methods. Forty healthy female volunteers between 18 and 30 years participated in the study. The volunteers were submitted to two different evaluations: clinical analysis and baropodometry. During the exams, different insole components were tested. The statistical analysis of the two evaluations revealed differences regarding the normalization of posture following the application of the insole components and in the determination of the combination of these components. The findings suggest that the clinical analysis is a fast and accurate method for determining the immediate benefits of the postural insole components and is therefore the more indicated method for the evaluation of foot posture, but does not present a concrete foundation to differentiate it with respect to baropodometric evaluation in the assessment and diagnosis of foot posture, however, a greater difficulty was encountered in achieving posture normalization when using information obtained through baropodometry.

  10. Cushing's syndrome: from physiological principles to diagnosis and clinical care.

    The physiological control of cortisol synthesis in the adrenal cortex involves stimulation of adrenocorticotrophic hormone (ACTH) by hypothalamic corticotrophin-releasing hormone (CRH) and then stimulation of the adrenal by ACTH. The control loop of the hypothalamic-pituitary-adrenal (HPA) axis is closed by negative feedback of cortisol on the hypothalamus and pituitary. Understanding this system is required to master the diagnosis, differential diagnosis and treatment of endogenous hypercortisolism--Cushing's syndrome. Endogenous Cushing's syndrome is caused either by excess ACTH secretion or by autonomous cortisol release from the adrenal cortex. Diagnosis of cortisol excess exploits three physiological principles: failure to achieve the normal nadir in the cortisol diurnal rhythm, loss of sensitivity of ACTH-secreting tumours to cortisol negative feedback, and increased excretion of free cortisol in the urine. Differentiating a pituitary source of excess ACTH (Cushing's disease) from an ectopic source is accomplished by imaging the pituitary and sampling for ACTH in the venous drainage of the pituitary. With surgical removal of ACTH or cortisol-secreting tumours, secondary adrenal insufficiency ensues because of the prior suppression of the HPA axis by glucocorticoid negative feedback. Medical therapy is targeted to the anatomical location of the dysregulated component of the HPA axis. Future research will focus on new diagnostics and treatments of Cushing's syndrome. These are elegant examples of translational research: understanding basic physiology informs the development of new approaches to diagnosis and treatment. Appreciating pathophysiology generates new areas for inquiry of basic physiological and biochemical mechanisms. © 2014 The Authors. The Journal of Physiology © 2014 The Physiological Society.

    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 (x 2 = 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

    A 4-year-old, 37 kg, male German shepherd developed hyperthermia, tachycardia, and agitation following consumption of ground meat found in the backyard of its owner. When presented to a veterinary clinic, plasma ethylene glycol (EG) testing was positive, and the dog was given ethanol and lactated Ringer's solution intravenously. Approximately 11 h postexposure the dog died. Among tissues submitted for toxicological analysis, urine was negative for EG, ground meat was negative for certain drugs of abuse, and gastric contents were negative for zinc/aluminum phosphide and metaldehyde. Analysis of gastric contents by gas chromatography-mass spectrometry confirmed the presence of caffeine. Caffeine concentration in the ground meat was estimated at 1 %. Caffeine is a methylxanthine alkaloid with a reported canine oral median lethal dose (MLD(50)) of 140 mg/kg (range 120-200 mg/kg). A commercially available 200-mg tablet formulation of caffeine was considered to be a possible source but this was not confirmed. By conservative estimates, the dog would need to ingest approximately 500-550 g of the meat to reach the MLD(50). Acute intoxication affects the cardiovascular, pulmonary, neurologic, gastrointestinal, and metabolic systems. Although no tablet remnants were observed in the bait, tablets could have been crushed and/or dissolved. Other potential caffeine sources include guarana, brewed and concentrated coffee, and caffeine-containing beverages. Based on the history, clinical signs, and the detection of caffeine in the gastric contents and meat, a presumptive diagnosis of malicious caffeine poisoning was made. A suggested treatment regimen for caffeine intoxication in dogs is described. While few cases of accidental ingestion of caffeine by dogs have been described, the intentional use of a concentrated caffeine source to cause mortality in a dog has not been previously reported.

    2009-02-01

    Atypical odontalgia (AO) is a poorly understood and commonly misdiagnosed condition for which patients often undergo multiple unsuccessful dental or surgical procedures. The authors conducted a study to determine the prevalence and describe the characteristics of patients with AO seen at the University of Southern California Orofacial Pain and Oral Medicine Center (USC OFP-OM Center), Los Angeles. The authors conducted a retrospective record review from a database of more than 3,000 patient records from June 2003 to August 2007 to identify patients diagnosed with AO. The authors identified 64 patients (44 women and 20 men) between the ages of 26 and 93 years as having a diagnosis of AO. Of those 64 patients, 71 percent initially consulted a dentist regarding their pain, and 79 percent had undergone dental treatment that failed to resolve the pain. The pain of 64 percent of the patients had no known cause. Dentists, who often are the first health care providers to see patients with AO, must be aware of this condition and must follow the appropriate steps to determine its diagnosis. Dentists and physicians should understand the implications and importance of early diagnosis of patients with AO and of referral to pain specialists for treatment.

    Accurate clinical diagnosis of fibroadenoma in young females is desirable because of the possibility of nonoperative treatment for those desiring it. To determine the accuracy of the clinical diagnosis of fibroadenoma in patients aged ≤ 25 years. A prospective study of all patients with breast disease presenting to the breast clinic was conducted from January 2004 to December 2008. During the study period, 145 patients aged ≤25 years presented with breast lumps. In this group, a clinical diagnosis of fibroadenoma was made in 100 (69.0%), fibrocystic disease in 32 (22.1%), breast cancer in 4 (0.03%) patients, the remaining were benign lesions. Excision biopsy was done for 81 (55.9%) patients. Of these 81 patients, only 62 (76.5%) returned with histology report. The histological diagnosis was fibroadenoma in 45 (72.5%) patients with a mean age of 21.4 years. Their ages range from 18 to 25 years. The histological diagnosis was fibrocystic disease in 9 (14.5%) and malignant phyllodes in 1 (1.6%) patient. The remaining 7 (11.3%) patients had other types of benign lesions. For fibroadenoma, true positive cases were 42, false positive 7 and false negative 3, and true negative 10. Therefore, the sensitivity of clinical diagnosis of fibroadenoma was 93.3%, while specificity was 58.8%. The sensitivity of clinical diagnosis of fibroadenoma in patients aged ≤25 years was good, though specificity is low.

  16. A Minimalist and Garantistic Conception of the Presumption of Innocence

    Directory of Open Access Journals (Sweden)

    Jordi Ferrer Beltrán

    2018-03-01

    Full Text Available The article aims to address the multiple faces that the presumption of innocence incorporates in modern legal systems from a critical perspective. In this sense, an analytical methodology seeks to demonstrate that some of these faces overlap with other legal rights and institutes, which, far from increasing the guarantees of citizens, leads to confusion and lack of controllability of judicial decisions. Thus, it is defended the conceptual and practical convenience of thinking the presumption of innocence avoiding overlaps with other legal rights or concepts, as standards of proof or burden of proof rules. Hence the reference to a minimalist and guarantistic conception of the presumption of innocence and, and, as will be seen, the defense of the presumption of innocence as a second order rule whose application would make sense in contexts of uncertainty about the satisfaction of the standard of proof.

    Gene Xpert(GX) is a novel real time polymerase chain reaction (RT-PCR) assay which was endorsed by the World Health Organization (WHO) in 2011 for tuberculosis (TB) diagnosis and susceptibility to refampicin(RIF). To evaluate GX for direct diagnosis of TB in stool samples from children with suspected pulmonary Tuberculosis (PTB). Children older than one year and younger than 16 years with presumptive PTB were enrolled and classified to five clinical categories based on clinical, radiological, and laboratory findings: confirmed TB, probable TB, possible TB, Unlikely TB, and not TB. Two stool samples were collected from each child and tested for the presence of Mycobacterium tuberculosis (MTB) by GX and the obtained results were compared to Lowenstien-Jensen (LJ) culture as a gold standard. In total, 115 children were enrolled. 36 had been confirmed with TB, 61 probably TB, 10 possible TB, 5 unlikely TB, and 3 not TB. GX had a sensitivity of 83.33 and 80.56 % and specificity of 98.73 and 99.36 % by patients and samples respectively. GX was positive in 83.3% of confirmed TB as well as 1.6 and 0.8% of probable TB cases by patients and samples respectively. GX provided timely results with quit acceptable sensitivity and good specificity compared to LJ culture. In this study, sensitivity calculations take into account only children with confirmed TB. GX could not detect TB in children with probable TB, so it should not be used alone for TB diagnosis. Further studies for GX stool protocol optimization and assessment is required. © 2016 by the Association of Clinical Scientists, Inc.

    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

    Thymoma is a disease with malignant potential, which has a recurrence rate after complete resection ranging from 5 to 50 %. Multiple studies on the risk factors, treatment or prognosis have been reported. Many of them are controversial, however. In this review, we summarized some accepted risk factors, means of diagnosis and different treatments of recurrent thymoma. The risk factors of recurrent thymoma haven't been well-studied, and its management remains controversial. We reviewed the literatures and found some key points which should be noticed during the surgery of initial thymoma. Although reoperation should be taken into account preferentially, multimodal treatments are also available. The prognosis are also been discussed.

  5. The Presumption of Innocence as a Counterfactual Principle

    Directory of Open Access Journals (Sweden)

    Ferry de Jong

    2016-01-01

    Full Text Available This article’s primary aim is to highlight the essentially critical potential of the presumption of innocence, as well as the need for this critical potential to be duly recognized. It is argued that the essential meaning of the presumption of innocence is best understood when approached from what is referred to as its counterfactual status. As a first step, the different values and functions that are attributed to the presumption of innocence in contemporary legal literature are discussed, in order to provide an outline of the central ideas it contains or is supposed to contain. Subsequently, the concept of ‘counterfactuality’ is introduced and it is argued that a counterfactual perspective can further clarify the nature of the presumption of innocence. Next, a number of fundamental shifts in society and criminal justice are discussed that affect the presumption of innocence and that lend a large measure of urgency to disclosing its essence and critical potential. The conclusion argues that today’s threats to the presumption of innocence are of a fundamental nature, and that attempts to preserve the principle’s efficacy should focus on the value attached to its counterfactual and critical nature.

    Holmes, Robert E; Barfield, William R; Woolf, Shane K

    2015-07-01

    Shoulder pain and dysfunction is a complex problem frequently encountered by primary care physicians. Common nonarthritic conditions seen in the primary care setting include rotator cuff syndrome, impingement, posttraumatic stiffness, adhesive capsulitis, and instability. A thorough history and physical examination can aid in the diagnosis of many common shoulder complaints. Pain and instability are the most common shoulder complaints. Pain that is sharp or burning is commonly radicular in origin, whereas pain caused by tendinitis is often dull, diffuse, and aching. Instability is frequently found in patients with a history of dislocation, but also may occur with no prior history. Imaging modalities such as magnetic resonance imaging can be helpful for more advanced pathology. However, many common shoulder conditions can be diagnosed without imaging, and may be initially treated with a short course of rest, ice, topical analgesics, nonsteroidal anti-inflammatory drugs, directed and supervised physical therapy, and occasionally subacromial corticosteroid injections. As always, a detailed history and a thorough physical exam by a primary care physician are vital for diagnosis. When conservative measures fail, referral to an orthopaedic surgeon may be necessary for further patient management.

  12. Huntington Disease: The Complexities of Making and Disclosing a Clinical Diagnosis After Premanifest Genetic Testing.

    McCusker, Elizabeth A; Loy, Clement T

    2017-01-01

    The management of patients and families affected by Huntington disease (HD) is complicated by several factors, both practical and ethical. It can be difficult to determine the onset of clinically manifest HD (mHD). In addition, it can be challenging to decide when to disclose the diagnosis to the affected individual. Firstly, the features of HD, an incurable, inherited, neurocognitive disorder that often manifests in young adulthood, influence how the person presents and accepts a diagnosis. Secondly, a positive genetic test for HD may result in a genetic diagnosis, sometimes years before the development of clinical features and the diagnosis of mHD. Thirdly, observational studies of unaffected gene expansion carriers documented HD manifestations up to 10 years before the typical presentation for diagnosis. These developments may permit earlier genetic diagnosis and information regarding the patient's likely status with respect to the development of clinical disease. Making the genetic diagnosis of HD and providing information regarding disease status, earlier rather than later, respects the person's right to know and preserves honesty in the doctor/patient relationship. Conversely, delaying the diagnosis respects the right not to know, avoids potential discrimination, and permits the person to live a "normal" life for longer, in the context of a disease without cure. This discussion has implications for other inherited and neurocognitive disorders.

    2017-01-01

    Dental injuries, especially luxation and avulsion, are common. Dental trauma can cause alveolar bone fracture that can lead to tooth loss and malocclusion. Single tooth alveolar bone fractures are difficult to identify unless it protrudes through the overlying mucosa and can be visualized. Pain, malocclusion, and tooth mobility provide signs of suspected alveolar bone fractures. Integrity of the proximate alveolar bone should be examined for fractures where avulsion, luxation, or other tooth trauma is detected. Any suggestion of alveolar fractures should be further investigated with an appropriate radiograph. This case report shows a pathognomonic sign that detects and diagnosis single tooth alveolar bone fractures, i.e. , a localized hematoma crossing the attached gingiva from the free gingival margin to the vestibular mucosa. This should serve as a warning for localized alveolar bone fracture. A visualized hematoma and gentle, careful palpation may help detect covered fractures when the overlying mucosa is not perforated.

    Non-communicable diseases are a public health problem in México. Coronary heart disease and diabetes mellitus are the first and second cause of death in the country, followed by thrombotic cerebrovascular events. Cardiovascular diseases are the leading cause of death; one primary risk factor is hypercholesterolemia. The detection and treatment of lipid abnormalities is the key to the prevention and management of chronic non-communicable diseases. Two nationally representative surveys have shown that lipid abnormalities are the most common risk factors in Mexican adults. The purpose of this guide is to provide a basis for identifying dyslipidemia in a timely manner, and to systematize the criteria for diagnosis and treatment in the first and second level of care.

    Validate the nursing diagnosis spiritual distress in cancer patients. Cross-sectional approach using Richard Fehring's Clinical Diagnostic Validity Model. The prevalence of diagnosis was 40.8% in a sample of 170 patients. A total of 16 defining characteristics were validated. Expresses suffering had the highest sensitivity value and lack of meaning in life had the highest specificity value. The diagnosis was validated. Cancer patients in spiritual distress are in a state of suffering related to lack of meaning in life. Sensitive diagnosis tools and language are required for nurses to make accurate judgments in situations of spiritual distress. Validation in different contexts would increase the clinical evidence of this diagnosis. © 2015 NANDA International, Inc.

    Conclusion: Because the imaging of orbital wooden foreign bodies is complex and varied, MRI should be combined when they are invisible on CT scan. At the same time injuries trajectory and clinical manifestations of patients should be taken into account. Surgical exploration should be extensive and thorough, and foreign bodies and orbital abscess must be cleared.

  1. Clinical practice guidelines for the diagnosis and management of melanoma: melanomas that lack classical clinical features.

    Science.gov (United States)

    Mar, Victoria J; Chamberlain, Alex J; Kelly, John W; Murray, William K; Thompson, John F

    2017-10-16

    A Cancer Council Australia multidisciplinary working group is currently revising and updating the 2008 evidence-based clinical practice guidelines for the management of cutaneous melanoma. While there have been many recent improvements in treatment options for metastatic melanoma, early diagnosis remains critical to reducing mortality from the disease. Improved awareness of the atypical presentations of this common malignancy is required to achieve this. A chapter of the new guidelines was therefore developed to aid recognition of atypical melanomas. Main recommendations: Because thick, life-threatening melanomas may lack the more classical ABCD (asymmetry, border irregularity, colour variegation, diameter > 6 mm) features of melanoma, a thorough history of the lesion with regard to change in morphology and growth over time is essential. Any lesion that is changing in morphology or growing over a period of more than one month should be excised or referred for prompt expert opinion. Changes in management as a result of the guidelines: These guidelines provide greater emphasis on improved recognition of the atypical presentations of melanoma, in particular nodular, desmoplastic and acral lentiginous subtypes, with particular awareness of hypomelanotic and amelanotic lesions.

  2. Tattoo complaints and complications: diagnosis and clinical spectrum.

    Tattoos cause a broad range of clinical problems. Mild complaints, especially sensitivity to sun, are very common and seen in 1/5 of cases. Medical complications are dominated by allergy to tattoo pigment haptens or haptens generated in the skin, especially in red tattoos but also in blue and green tattoos. Symptoms are major and can be compared to cumbersome pruritic skin diseases. Tattoo allergies and local reactions show distinct clinical manifestations, with plaque-like, excessive hyperkeratotic, ulcero-necrotic, lymphopathic, neuro-sensory, and scar patterns. Reactions in black tattoos are papulo-nodular and non-allergic and associated with the agglomeration of nanoparticulate carbon black. Tattoo complications include effects on general health conditions and complications in the psycho-social sphere. Tattoo infections with bacteria, especially staphylococci, which may be resistant to multiple antibiotics, may be prominent and may progress into life-threatening sepsis. Contaminated tattoo ink is an open-window risk vector that can lead to epidemic tattoo infections across national borders due to contaminated bulk production. Hepatitis B and C and human immunodeficiency virus (HIV) transferred by tattooing remain a significant risk needing active prevention. It is noteworthy that cancer arising in tattoos, in regional lymph nodes, and in other organs due to tattoo pigments and ingredients has not been detected or noted as a significant clinical problem hitherto, despite millions of people being tattooed for decennia. Clinical observation and epidemiology disagree with register data, which indicate an increased risk of cancer due to chemical carcinogens present in some inks. Registers rely on chronic dosaging of cell lines and animals. However, tattooing in humans is essentially a single-dose exposure, which might explain the observed discrepancy. © 2015 S.

    Malignant melanoma belongs to the most malignant and aggressive tumors due to its fast growing metastasis. Despite the fact that the incidence of melanoma has been on the increase for the past years and mortality to low and medium risk melanoma has decreased, the mortality of aggressive fast growing high risk melanomas has been stable. Diagnosis of “typical” melanomas, fulfilling ABCDEF criteria, usually does not cause any problems. Particular attention should be paid to the problems of fast growing melanomas, which are very similar to benign lesions at the beginning so they are often detected too late. Melanomas have two extreme properties: on one edge of the spectrum there are patients with small and thin skin lesions, who are usually completely cured by wide surgical excision. On the other edge of the spectrum there are patients with generalized metastatic disease. In these patients the treatment options are very limited and the probability to survive is about 6-9 months. The most significant factor for survival is the early melanoma detection. (author)

    Matrix metalloproteinase-9 and its tissue inhibitor TIMP-1 have been documented as putative tumor markers because of their involvement in cancer invasion and metastasis. The aim of our study was to elucidate the diagnostic efficacy of proteolytic activity markers among traditional tumor markers (CEA and CA15.3) and clinicopathological variables. Serum samples were withdrawn from 160 individuals (80 patients with primary breast cancer, 40 patients with benign breast lesions and 40 individuals serve as healthy controls). MMP-9 and TIMP-1 were measured by ELISA and gelatin zymography. The best cutoff points for MMP-9 and TIMP-1 were depicted by receiver operating characteristic (ROC) curve. The positivity rates and the median levels for MMP-9 and TIMP-1 showed significant difference among the three investigated groups (Phormonal receptor status (ER, and PgR). MMP zymography results were comparable to those from ELISA. The sensitivity and the specificity of MMP-9, TIMP-1 and MMP-9/TIMP-1 were superior to traditional tumor markers (CEA and CA15.3) especially for early stages (T1) and low grade breast cancer patients. These findings indicate that investigated biomarkers are constructive for early diagnosis of breast cancer and MMP-9/TIMP-1 ratio might be a new significant marker in predicting breast cancer development.

    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.) [de

    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

    The aim of the study was to investigate whether the preclinical stage of Alzheimer's disease (AD) can be diagnosed in a clinical setting. To this end we investigated whether subjects with preclinical AD could be differentiated from subjects with nonprogressive mild cognitive impairment and from subjects with very mild AD-type dementia. Twenty-three subjects with preclinical AD, 44 subjects with nonprogressive mild cognitive impairment, and 25 subjects with very mild AD-type dementia were selected from a memory clinic population. Variables that were used to differentiate the groups were demographic variables, the Mini-Mental State Examination score, performance on cognitive tests, measures of functional impairment, and measures of noncognitive symptomatology. Age and the scores for the delayed recall task could best discriminate between subjects with preclinical AD and subjects with nonprogressive mild cognitive impairment. The overall accuracy was 87%. The score on the Global Deterioration Scale and a measure of intelligence could best discriminate between subjects with preclinical AD and subjects with very mild AD-type dementia. The overall accuracy was 85%. Subjects with preclinical AD can be distinguished from subjects with nonprogressive mild cognitive impairment and from subjects with very mild AD-type dementia. This means that preclinical AD is a diagnostic entity for which clinical criteria should be developed.

  11. Telomerase in cancer diagnosis and therapy: a clinical perspective.

    Burger, A M

    1999-12-01

    Curing cancers is one of the most challenging tasks of modern medicine. The major problem is the heterogeneity of human tumours and thus finding a 'universal' target for cancer treatment. The discovery that the expression of the enzyme telomerase is a hallmark of immortality and cancer, and that it is found in the majority (>85%) of human tumours but is repressed in most normal cells, has therefore caused considerable excitement. These observations led to the design of potential telomerase inhibitors and ideas about targeting telomerase in the clinic. To date, several classes of telomerase inhibitory agents have been identified and are in preclinical development. However, the approach has not yet been tested clinically. Because of the proposed function of telomerase, and the understanding that replicative cell senescence or cell death result from progressive telomere shortening during successive cell divisions, even complete enzyme inhibition will not produce immediate cell death. Designing clinical trials for promising telomerase inhibitors requires consideration of the novel mechanism of action of these drugs. A lag period between initiation of treatment and occurrence of effects is likely, and thus anti-telomerase therapy might best be given in adjuvant treatment protocols after initial tumour debulking therapy and in combination with other cytostatic agents. The available knowledge of telomerase biology and its association with human tumours suggests that telomerase inhibition might prove a valuable addition to current cancer treatment regimens.

    Full Text Available We report a case of isolated homonymous hemianopsia due to presumptive cerebral tubercular abscess as the initial manifestation of human immunodeficiency virus (HIV infection. A 30-year-old man presented to our outpatient department with sudden loss of visibility in his left visual field. He had no other systemic symptoms. Perimetry showed left-sided incongruous homonymous hemianopsia denser above the horizontal meridian. Magnetic resonance imaging revealed irregular well-marginated lobulated lesions right temporo-occipital cerebral hemisphere and left high fronto-parietal cerebral hemisphere suggestive of brain tubercular abscess. Serological tests for HIV were reactive, and the patient was started only on anti-tubercular drugs with the presumptive diagnosis of cerebral tubercular abscess. Therapeutic response confirmed the diagnosis. Atypical ophthalmic manifestations may be the initial presenting feature in patients with HIV infection. This highlights the need for increased index of suspicion for HIV infection in young patients with atypical ophthalmic manifestations.

    Full Text Available When seeking a confirmed molecular diagnosis in the research setting, patients with one descriptive diagnosis of retinal disease could carry pathogenic variants in genes not specifically associated with that description. However, this event has not been evaluated systematically in clinical diagnostic laboratories that validate fully all target genes to minimize false negatives/positives.We performed targeted next-generation sequencing analysis on 207 ocular disease-related genes for 42 patients whose DNA had been tested negative for disease-specific panels of genes known to be associated with retinitis pigmentosa, Leber congenital amaurosis, or exudative vitreoretinopathy.Pathogenic variants, including single nucleotide variations and copy number variations, were identified in 9 patients, including 6 with variants in syndromic retinal disease genes and 3 whose molecular diagnosis could not be distinguished easily from their submitted clinical diagnosis, accounting for 21% (9/42 of the unsolved cases.Our study underscores the clinical and genetic heterogeneity of retinal disorders and provides valuable reference to estimate the fraction of clinical samples whose retinal disorders could be explained by genes not specifically associated with the corresponding clinical diagnosis. Our data suggest that sequencing a larger set of retinal disorder related genes can increase the molecular diagnostic yield, especially for clinically hard-to-distinguish cases.

    2006-01-01

    Dens invaginatus, commonly known as dens in dente, is a developmental malformation of teeth that most commonly affects permanent maxillary lateral incisors. Deciduous teeth are infrequently affected. Presence of dens invaginatus in mandibular permanent teeth is extremely uncommon. A rare presentation of coronal double dens invaginatus incidentally detected in a mandibular canine tooth on radiographic examination is being reported, along with a discussion of this anomaly. The patient had presented for routine dental treatment unrelated to this finding. In addition, the various radiographic appearances of dens invaginatus, as they present within the maxillary and mandibular teeth, are described. Essential clinical considerations and treatment options are presented. A review of the pertinent literature is undertaken, and tables summarizing previously published reports of mandibular dens invaginatus and double dens invaginatus are presented. A review of the literature indicates that dens invaginatus in mandibular teeth is extremely rare, with only 11 other cases, involving 14 teeth, reported previously. Cases of double dens invaginatus are even more atypical, with only eight previously reported cases. Dens invaginatus is an anomaly that should be familiar to all practicing dentists because of the clinical implications and potential sequelae.

    The diagnosis of small diameter melanoma, that is early melanoma, is particularly difficult. For this reason we decided to evaluate the improvement given from our diagnostic dermoscopic method 7FFM to the clinical diagnosis, ABCDE rule, of small diameter melanoma. A retrospective study evaluating the clinical and the dermoscopic slides of 76 small diameter melanomas observed from January 1 1993 to December 31 1998, and of 524 small melanocytic nevi consecutively observed from September 1 1997 to September 30 1999, has been undertaken. The sensitivity and the specificity of the ABCDE rule and of our diagnostic dermoscopic method 7FFM in the diagnosis of small diameter melanoma have been calculated. The difference of diagnostic power between the two methods has been calculated with chi square test. The sensitivity and the specificity of the ABCDE rule in the diagnosis of small melanomas were 47.3% and 56%, while the sensitivity and the specificity of our method 7FFM were 68.8% and 86%. The difference of diagnostic power between the two methods was statistically significant: P<0.01 for both sensitivity and specificity. The sensitivity of the two methods together was 81.5% while the specificity of the two methods together was 50.6%. Our results show that our diagnostic dermoscopic method 7FFM improves both sensitivity and specificity in the clinical diagnosis of small diameter melanomas. Anyway the clinical and the dermoscopic diagnosis are not mutually exclusive as the best sensitivity is obtained with the two methods together.

    It is common that children confront psychological problems when they reach puberty. These problems could easily be overcome, but in many cases they could be severe, leading to social estrangement or worse in madness or death. According to information collected we designed a questionnaire about the psychology of adolescents in order to help people in that age or their elders find out if they have health issues. We used already published researches and material concerning all the psychological problems a child can confront in order to make a reliable questionnaire and to develop the clinical decision support system. Our main objective is to publish and administrate a web-based free tool for sharing medical knowledge about any psychological disease a child can already have or develop during puberty.

    Detection of an intracardiac mass always represents a clinical challenge. We present a 61-year-old female patient with symptoms of New York Heart Association class III. Two-dimensional transthoracic echocardiography revealed a hypoechogenic mass in the cavity of the dilated right ventricle (RV). Cardiac MRI described a pathologic structure of the RV free wall with pedunculated tumor in its cavity. Three months later, on a repeated echocardiography, there were three individual masses. The patient underwent surgery and the pathohistologic report demonstrated thrombotic masses. During the postoperative period, after reviewing all medical records, the conclusion was arrhythmogenic RV cardiomyopathy. © 2016 Wiley Periodicals, Inc.

  2. Diagnosis and clinical genetics of Cushing syndrome in pediatrics

    Science.gov (United States)

    Stratakis, Constantine A.

    2016-01-01

    SYNOPSIS Endogenous Cushing syndrome (CS) in pediatrics is rare; it may be caused by tumors that produce corticotropin (ACTH) in the pituitary gland (this form of CS is called Cushing disease) or elsewhere (ectopic CS), tumors that produce corticotropin-releasing hormone (CRH) anywhere (mostly neuroendocrine tissues), and finally adrenocortical masses that produce cortisol, such as adrenocortical cancer (ACC) or adenomas, and bilateral adrenocortical hypeprlasia (BAHs). ACC is a very rare cause of CS in children but should be excluded first, especially among younger patients. CS in children is often caused by germline or somatic mutations in an expanding list of genes with implications for the prognosis of the patients and for their families. CS should be early recognized in children; otherwise, it can lead to significant morbidity and mortality. All patients with suspected CS should be referred to specialized clinical centers for work-up; these centers should have access to experienced endocrine and neurological surgeons. PMID:27241967

  3. Osteogenesis imperfecta: clinical diagnosis, nomenclature and severity assessment.

    2014-06-01

    Recently, the genetic heterogeneity in osteogenesis imperfecta (OI), proposed in 1979 by Sillence et al., has been confirmed with molecular genetic studies. At present, 17 genetic causes of OI and closely related disorders have been identified and it is expected that more will follow. Unlike most reviews that have been published in the last decade on the genetic causes and biochemical processes leading to OI, this review focuses on the clinical classification of OI and elaborates on the newly proposed OI classification from 2010, which returned to a descriptive and numerical grouping of five OI syndromic groups. The new OI nomenclature and the pre-and postnatal severity assessment introduced in this review, emphasize the importance of phenotyping in order to diagnose, classify, and assess severity of OI. This will provide patients and their families with insight into the probable course of the disorder and it will allow physicians to evaluate the effect of therapy. A careful clinical description in combination with knowledge of the specific molecular genetic cause is the starting point for development and assessment of therapy in patients with heritable disorders including OI. © 2014 The Authors.

    Moebius syndrome (MBS) is rare disease characterized by nonprogressive congenital uni- or bi-lateral facial (i. e. VII cranial nerve) and abducens (i. e. VI cranial nerve) palsy. Although the neurological and ophthalmological findings are quite well-known, data concerning the attendant functional difficulties and their changes over time are seldom addressed. In this study we attempt to estimate the prevalence of clinical and functional data in an Italian cohort affected by MBS. The study included 50 children, 21 males and 29 females, aged 1 month to 14 years. The patients entered into a multidisciplinary diagnostic and follow-up protocol that had the specific purpose of detecting clinical and developmental deficits related to MBS. Involvement of the VII cranial nerve (total/partial, bilateral or unilateral) was present in 96 % of patients, and of the VI nerve in 85 %. Two patients were without impairment of the VII nerve and seven patients had no involvement of the VI nerve and were thus classified as Moebius-like because of the involvement of other CNs. Additional affected CNs were numbers III-IV in 16 %, V in 11 %, VIII and X each in 8 %, the XI in 6 %, the IX, most often partially, in 22 %, and the XII in 48 % of cases. Their development was characterized by global delay at one year of age, motor, emotional and speech difficulties at two years of age, a trend toward normalization at three years of age but with weakness in hand-eye coordination, and achieving average results at five years of age. Overall 90 % of children had a normal developmental quotient whereas only 10 % manifested cognitive deficits. Early rehabilitation may enhance the recovery of normal function, particularly in vulnerable areas of development. It is possible that early intervention that integrates sensory and visual information with emotional difficulties can improve the prognosis of the child with MBS.

    Full Text Available Background: Immunobullous diseases are morphologically heterogeneous and the differentiation between various subtypes is essential for proper treatment and prognosis. Aim of our study was to analyze and correlate clinical, histopathological and immunofluorescence findings in autoimmune bullous diseases. Materials and Methods: A cross-sectional study was done over a period of two years (2010-2012 after approval of the ethics committee. Sixty patients, who met the inclusion criteria of immunobullous disease, were included in the study. Skin biopsy for histopathology and direct immunofluorescence (DIF examination was taken. DIF using salt-split technique was done in few of the cases. The final diagnosis was based on clinical, histopathology and DIF findings. Pearson′s coefficient of correlation (r was calculated. Statistical Analysis was done using Epi info version. 7.0. Results: Fifty-three cases with clinical diagnosis of autoimmune bullous diseases were evaluated. In 88.6% of cases, histopathology diagnosis was consistent with clinical diagnosis and in 75.5% of cases, DIF findings were consistent with clinical diagnosis. A positive relation was seen between clinical and DIF findings with r = 0.65 and between histopathology and DIF findings with r = 0.75. DIF positivity was seen in 100% cases of bullous pemphigoid (BP and pemphigus foliaceous and 94.7% cases of pemphigus vulgaris, which was statistically significant with p < 0.05. In DIF salt-split test, deposition was seen on roof of blister in BP whereas on floor in epidermolysis bullosa acquisita. Conclusion: Our study provides evidence-based guidance for the diagnosis and classification of various immunobullous disorders. DIF test should be done in conjunction with histopathology for definitive diagnosis and to minimize both: False-positive and false-negative results.

    Full Text Available Diagnosis of fissural caries, especially in young permanent teeth, is quite difficult to establish, its sometimes aleatory character possibly leading to incorrect therapeutical decisions. The aim of the study is to evaluate laser fluorescence (LF represented by Diagnodent as a diagnosis means, comparatively with the exams involving inspection and probing (VI, the validation test of which is the exploratory drilling. Method: 72 occlusal surfaces of the permanent molars of 10-15 year-old children have been examined, the diagnosis being established by two methods; after validation of the diagnosis through exploratory drilling, specific treatments were performed, exemplified by self-evident clinical cases. Results: The obtained values are: VI sensitivity 68.1%, LF 83.3%, specificity VI 77.7%, LF 50%, comparable with the results of other studies. Conclusions: Due to its increased sensitivity, Diagnodent completes the examination through inspection and probing, for the establishment of a correct diagnosis and treatment of fissural caries.

    The clinical significance of CT in the preoperative diagnosis of colon and rectal cancer was studied. Thirty four patients were investigated in this series. The diagnostic criteria of the CT examination were previously established in a study of wall invasion (S factor), lymph node metastasis (N factor), liver metastasis (H factor) and peritoneal dissemination (P factor). The CT diagnosis was done prospectively according to these criteria, and the CT diagnosis was compared with the macroscopic and histological diagnosis. The accuracy of the prospective diagnosis as to H, S, N and P factors was 79.4 %, 55.9 %, 41.2 % and 20.6 %, respectively. The diagnostic value of CT seemed to be acceptable as to the H factor, but limited to some extent to the S and N factors. (author)

    There is limited evidence for defining what specific method or methods should be used to clinically influence clinical decision making for forefoot neuroma. The aim of this study was to develop a clinical assessment protocol that has agreed expert consensus for the clinical diagnosis of forefoot neuroma. A four-round Delphi consensus study was completed with 16 expert health professionals from either a clinical or clinical academic background, following completion of a structured literature review. Clinical experience ranged from 5 to 34 years (mean: 19.5 years). Consensus was sought on the optimal methods to achieve the clinical diagnosis of forefoot neuroma. Round 1 sought individual input with an open ended question. This developed a list of recommendations. Round 2 and 3 asked the participants to accept or reject each of the recommendations in the list in relation to the question: "What is the best way to clinically diagnose neuroma in the forefoot?" Votes that were equal to or greater than 60% were accepted into the next round; participant's votes equal to or less then 20% were excluded. The remaining participant's votes between 20 to 60% were accepted and placed into the following round for voting. Round 4 asked the participants to rank the list of recommendations according to the strength of recommendation they would give in relation to the question: "What is the best way to clinically diagnose neuroma in the forefoot?" The recruitment and Delphi rounds were conducted through email. In round 1, the 16 participants identified 68 recommendations for the clinical diagnosis of forefoot neuroma. In round 2, 27 recommendations were accepted, 11 recommendations were rejected and 30 recommendations were assigned to be re-voted on. In round 3, 36 recommendations were accepted, 22 recommendations were rejected and 11 recommendations were assigned to be re-voted on. In round 4, 21 recommendations were selected by the participants to form the expert derived clinical

    Fifty-five patients of cerebral occlusive diseases were studied using IMP and single photon emission tomograph (HEADTOME-II). Early imaging was begun after intravenous injection of IMP and delayed imaging was performed 3 hours more later. We classified the change of IMP distribution into 4 types, type 1: no uptake of the lesion in both early and delayed images, type 2: low IMP uptake of the lesion in early images but recognized redistribution of IMP is delayed images, type 3: high IMP uptake of the lesion in both early and delayed images, type 4: high IMP uptake of the lesion in early images but it decreased more rapidly in delayed images. In cases of type 3 and 4 recanalization of the occlusive arteries was found by cerebral angiography. The difference of IMP distribution has relation to the time of recanalization and the amount of collateral circulation at the lesion. Clinical prognosis shows a tendency to be better in cases of type 2 and 4 than type 1 and 3. IMP brain scans with SPECT seems useful for estimating the prognosis of patients. (author)

    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.

    Obstructive sleep-disordered breathing in children is a relatively common problem, presenting in various ways, from primary snoring, without an apparent decrease in quality of life, to obstructive sleep apnea with cognitive, cardiac, and growth abnormalities. History, clinical examination, radiologic evaluations, sleep studies, and other diagnostic modalities are reviewed. Since application and interpretation of these methods are not consistent in studies of snoring, a consensus on optimal treatment options has not been established. Traditionally, adenotonsillectomy has long been the treatment of choice. Treatment failures or recurrences as well as the existence of causes and contributing factors other than adenotonsillar hypertrophy, like obesity, facial malformations, and Down syndrome, have changed the concept of adenotonsillectomy as the ultimate cure. Several other treatment options have been proposed on their own or in combination. Continuous positive airway pressure, anti-inflammatory medications, maxillofacial, and orthodontic treatments are reviewed suggesting the need of a multidisciplinary approach in some cases. Finally, at the end of the chapter, a diagnostic and treatment work up based on current evidence is proposed for otherwise normal children or children with specific conditions.

    History taking and physical examination is the cornerstone of medical diagnosis as will lead to correct diagnosis 90% of the time. We report a case of a 30-year-old black African man with lymph node tuberculosis diagnosed one year and six months later after onset of symptoms and signs. Clinicians especially those in resource-limited settings should go in for thorough history taking and complete physical examination which is the basis for correct clinical diagnosis, will provide valuable guide in deciding which tests to order and thus laboratory tests done for confirmatory purposes and also, has a cost-effective benefit for the patient.

    With the awareness of osteoporosis as a major health problem for an aging population, there is great interest in early recognition and treatment of abnormal bone loss. Effective prevention of bone loss has to occur prior to the occurrence of irreparable damage. Standard radiographic procedures are not sensitive enough for the task. Therefore, a number of alternative procedures to estimate bone loss have been developed over the years, ranging from efforts to quantitate information obtained from radiographic images to sophisticated procedures such as neutron activation analysis or procedures based on the Compton scatter phenomenon. Only two procedures, photon absorptiometry and computed tomography (CT), have emerged as applicable for routine clinical use. In photon absorptiometry the entire bone mineral (cortical and trabecular bone) of a specific skeletal site is measured. CT allows measuring of bone mineral of trabecular or cortical bone alone. Normally, bone mass reaches a maximum in the third decade and then continuously declines. This age-related bone loss is greater in women in whom an accelerated rate of loss occurs at the menopause. When bone density reaches a critical fracture threshold, skeletal fractures occur (spine, hip, and distal long bones). The age at which this critical fracture threshold is reached depends on the maximal bone mass achieved in early adulthood and the rate of loss with increasing age. With the exception of NaF, present-day therapeutic efforts only retard or prevent bone loss but do not significantly add bone mineral to the skeleton. Recognition of high-risk groups and early treatment are therefore required. 79 references.

    Opportunistic screening in hospitals is widely used to effectively reduce the incidence rate of cervical cancer in China and other developing countries. This study aimed to identify clinical risk factor algorithms that combine gynecologic examination and molecular testing (paired box gene 1 (PAX1) or zinc finger protein 582 (ZNF582) methylation or HPV16/18) results to improve diagnostic accuracy. The delta Cp of methylated PAX1 and ZNF582 was obtained via quantitative methylation-specific PCR in a training set (57 CIN2- and 43 cervical intraepithelial neoplasia ≥grade 3 (CIN3+) women), and the individual and combination gene sensitivities and specificities were determined. The detection accuracy of three algorithms combining gynecologic findings and genetic test results was then compared in a randomized case-control study comprising 449 women referred for colposcopic examination by gynecologists in the outpatient department of Xiangya Hospital between November 2011 and March 2013. Significant association was observed between CIN3+ and methylated PAX1 or ZNF582 in combination with HPV16/18 (OR:15.52, 95 % CI:7.73-31.18). The sensitivities and specificities of methylated PAX1 or ZNF582 combined with HPV16/18 for CIN3+ women were 89.2 and 76.0 %, or 85.4 and 80.1 %, respectively. Of the three algorithms applied to cohort data and validated in the study, two indicated 100 % sensitivity in detecting cervical cancer and a low rate of referrals for colposcopy. These algorithms might contribute to precise and objective cervical cancer diagnostics in the outpatient departments of hospitals in countries with high mortality and low screening rates or areas with uneven resource distribution.

    Urticaria is a common skin condition that can compromise quality of life and may affect individual performance at work or school. Remission is common in majority of patients with acute spontaneous urticaria (ASU); however, in chronic cases, less than 50% had remission. Angioedema either alone or with urticaria is associated with a much lower remission rate. Proper investigation and treatment is thus required. This guideline, a joint development of the Dermatological Society of Thailand, the Allergy, Asthma, and Immunology Association of Thailand and the Pediatric Dermatological Society of Thailand, is graded and recommended based on published evidence and expert opinion. With simple algorithms, it is aimed to help guiding both adult and pediatric physicians to better managing patients who have urticaria with/without angioedema. Like other recent guideline, urticaria is classified into spontaneous versus inducible types. Patients present with angioedema or angioedema alone, drug association should be excluded, acetyl esterase inhibitors (ACEIs) and non-steroidal anti-inflammatory drugs (NSAIDs) in particular. Routine laboratory investigation is not cost-effective in chronic spontaneous urticaria (CSU), unless patients have clinical suggesting autoimmune diseases. Non-sedating H1-antihistamine is the first-line treatment for 2-4 weeks; if urticaria was not controlled, increasing the dose up to 4 times is recommended. Sedating first-generation antihistamines have not been proven more advantage than non-sedating antihistamines. The only strong evidence-based alternative regimen for CSU is an anti-IgE: omalizumab; due to very high cost it however might not be accessible in low-middle income countries. Non-pharmacotherapeutic means to minimize hyper-responsive skin are also important and recommended, such as prevention skin from drying, avoidance of hot shower, scrubbing, and excessive sun exposure.

    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.

    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.

    The aim of our study is to describe the types of dementia found in a series of patients and to estimate the level of agreement between the clinical diagnosis and post-mortem diagnosis. We conducted a descriptive analysis of the prevalence of the types of dementia found in our series and we established the level of concordance between the clinical and the post-mortem diagnoses. The diagnosis was made based on current diagnostic criteria. 114 cases were included. The most common clinical diagnoses both at a clinical and autopsy level were Alzheimer disease and mixed dementia but the prevalence was quite different. While at a clinical level, prevalence was 39% for Alzheimer disease and 18% for mixed dementia, in the autopsy level, prevalence was 22% and 34%, respectively. The agreement between the clinical and the autopsy diagnoses was 62% (95% CI 53-72%). Almost a third of our patients were not correctly diagnosed in vivo. The most common mistake was the underdiagnosis of cerebrovascular pathology. Copyright © 2016 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Vulval lichen sclerosus (LS) is a common inflammatory condition associated with an increased risk of developing vulval carcinoma. Diagnosis is usually clinical although biopsy is necessary if the diagnosis is uncertain or if there is a failure to respond to adequate initial treatment. Raman spectroscopy has the potential to be applied in vivo for near real time objective non-invasive optical diagnosis, avoiding the need for invasive tissue biopsies. The aim of this study was to evaluate the diagnostic performance of Raman spectroscopy for differentiating LS from other vulval conditions in fresh vulval biopsies. Biopsies were analysed from 27 women with suspected LS in whom the attending gynaecologist could not establish the diagnosis on clinical presentation alone. Spectral variance was explored using principal component analysis and in conjunction with the histological diagnoses was used to develop and test a multivariate linear discriminant classification model. This model was validated with leave one sample out cross validation and the diagnostic performance of the technique assessed in comparison with the pathology gold standard. After cross validation the technique was able to correctly differentiate LS from other inflammatory vulval conditions with a sensitivity of 91% and specificity of 80%. This study demonstrates Raman spectroscopy has potential as a technique for in vivo non-invasive diagnosis of vulval skin conditions. Applied in the clinical setting this technique may reduce the need for invasive tissue biopsy. Further in vivo study is needed to assess the ability of Raman spectroscopy to diagnose other vulval conditions before clinical application.

    It is not clear which young children presenting acutely unwell to primary care should be investigated for urinary tract infection (UTI) and whether or not dipstick testing should be used to inform antibiotic treatment. To develop algorithms to accurately identify pre-school children in whom urine should be obtained; assess whether or not dipstick urinalysis provides additional diagnostic information; and model algorithm cost-effectiveness. Multicentre, prospective diagnostic cohort study. Children blind to the reference standard, defined as a pure or predominant uropathogen cultured at ≥ 10(5) colony-forming units (CFU)/ml in a single research laboratory. Urine was collected by clean catch (preferred) or nappy pad. Index tests were sequentially evaluated in two groups, stratified by urine collection method: parent-reported symptoms with clinician-reported signs, and urine dipstick results. Diagnostic accuracy was quantified using area under receiver operating characteristic curve (AUROC) with 95% confidence interval (CI) and bootstrap-validated AUROC, and compared with the 'clinician diagnosis' AUROC. Decision-analytic models were used to identify optimal urine sampling strategy compared with 'clinical judgement'. A total of 7163 children were recruited, of whom 50% were female and 49% were children provided clean-catch samples, 94% of whom were ≥ 2 years old, with 2.2% meeting the UTI definition. Among these, 'clinical diagnosis' correctly identified 46.6% of positive cultures, with 94.7% specificity and an AUROC of 0.77 (95% CI 0.71 to 0.83). Four symptoms, three signs and three dipstick results were independently associated with UTI with an AUROC (95% CI; bootstrap-validated AUROC) of 0.89 (0.85 to 0.95; validated 0.88) for symptoms and signs, increasing to 0.93 (0.90 to 0.97; validated 0.90) with dipstick results. Nappy pad samples were provided from the other 2277 children, of whom 82% were children where clean catch is possible. Dipstick testing can

    Diagnosis of pelvic inflammatory disease is difficult. We focus on a systematic literature review to study diagnostic values of history-taking, clinical examination, laboratory tests and imagery. After this literature review, we build a diagnostic model for pelvic inflammatory disease. This diagnostic model is built on two major criteria: presence of adnexal tenderness or cervical motion tenderness. Additional minor criteria, increasing the likelihood of the diagnosis of pelvic inflammatory disease were added based on their specificity and their positive likelihood ratio. These minor criteria are supported by history-taking, clinical examination, laboratory tests and also on relevant ultrasonographic criteria. Copyright © 2012 Elsevier Masson SAS.

    The preliminary diagnosis of chronic periapical lesions is made on the basis of clinical symptoms and radiographs, which is a reliable diagnostic tool, but it has only a subsidiary role since histopathological verification is essential for the definitive diagnosis. This study was aimed at diagnosing removed chronic periapical lesions and classifying them by size as well as at comparing the clinical diagnoses with histipathological results. The study included 34 patients diagnosed with chronic periapical process by applying clinical examination and radiography. The removed chronic periapical lesions were processed according to classical histological technique and analyzed by hematoxylin and eosin staining protocol. According to histopathological analysis 53% of chronic periapical lesions were periapical granulomas and 47% were radicular cysts. The size of the lesions ranged from 20 mm (12% of lesions).The histopathological examination revealed that clinical diagnosis was wrong in 26% of cases. A statistically significant difference between clinical and histopathological diagnosis has been found. The histopathological findings strongly suggest the necessity of complete curettage of lesions sizing >20 mm in order to prevent recurrences.

    The British Psychological Society proposes that clinical psychologists are well placed to move beyond psychiatric diagnoses and develop alternative practices. This study sought to explore what the application of these guiding principles looks like in clinical practice, the challenges faced and possible routes forward. A purpose-designed survey was completed by 305 respondents and a thematic analysis completed. Thematic analysis was used to identify five superordinate themes relating to individuals, relational, others, structures and society, comprising of a total of 21 group themes. The presented group themes highlight an array of approaches to practicing beyond diagnosis and factors that help and hinder such action; from scaffolding change, becoming leaders, relating to the multi-disciplinary team, restructuring services and the processes of change. A key concept was "playing the diagnostic game". "Playing the diagnostic game" enables psychologists to manage an array of tensions and anxieties: conflicts between belief and practice, relationships with colleagues, and dilemmas of position and power. It also potentially limits a concerted questioning of diagnosis and consideration of alternatives. An alternative conceptual framework for non-diagnostic practice is needed to aid the collective efforts of clinical psychologists developing their practice beyond diagnosis, some of which have been highlighted in this study. Until then, ways of mitigating the perceived threats to questioning diagnosis need further exploration, theorising and backing.

    MRA is widely accepted as a noninvasive diagnostic tool for the detection of intracranial aneurysms, but detection is still a challenging task with rather low detection rates. Our aim was to examine the performance of a computer-aided diagnosis algorithm for detecting intracranial aneurysms on MRA in a clinical setting. Aneurysm detectability was evaluated retrospectively in 48 subjects with and without computer-aided diagnosis by 6 readers using a clinical 3D viewing system. Aneurysms ranged from 1.1 to 6.0 mm (mean = 3.12 mm, median = 2.50 mm). We conducted a multireader, multicase, double-crossover design, free-response, observer-performance study on sets of images from different MRA scanners by using DSA as the reference standard. Jackknife alternative free-response operating characteristic curve analysis with the figure of merit was used. For all readers combined, the mean figure of merit improved from 0.655 to 0.759, indicating a change in the figure of merit attributable to computer-aided diagnosis of 0.10 (95% CI, 0.03-0.18), which was statistically significant (F(1,47) = 7.00, P = .011). Five of the 6 radiologists had improved performance with computer-aided diagnosis, primarily due to increased sensitivity. In conditions similar to clinical practice, using computer-aided diagnosis significantly improved radiologists' detection of intracranial DSA-confirmed aneurysms of ≤6 mm. © 2014 by American Journal of Neuroradiology.

    2016-12-01

    National notifications for infectious syphilis in Australia have increased in recent years. Outside of sexual health clinics, junior clinicians seldom encounter this disease in its infectious stage (primary, secondary and early latent). With such a variable clinical presentation, textbook teaching is no substitute for real-life experience. The importance of accurate classification and staging of disease is relevant to the risk of transmission and determines treatment duration. In this article, the authors review the clinical presentation of syphilis over ten years in an urban sexual health clinic with a focus on the clinical presentation and diagnosis of infectious syphilis, in particular secondary syphilis, compared with that outlined in the Australian National Notifiable Diseases Surveillance System guidelines. This retrospective review of all patients diagnosed with syphilis at an urban sexual health clinic showed that between 2005 and 2015, 226 cases of syphilis were diagnosed. Documentation of impression of clinical staging of disease was present in 46% of the cases. Seventeen of these cases were recorded as secondary syphilis. The criteria used by clinicians to diagnose the secondary syphilis cases were consistent with criteria defined by the Australian National Notifiable Diseases Surveillance System. All cases of secondary syphilis had at least one cutaneous manifestation of disease. The demographic of the cohort of syphilis cases was consistent with that recorded in the literature. This review showed that the clinician's diagnosis of secondary syphilis in this service is consistent with the National Notifiable Diseases Surveillance System guidelines. Continuing education of junior medical staff is important to facilitate diagnosis and improve documentation of clinical staging, minimise disease transmission and ensure appropriate treatment. © The Author(s) 2016.

    Crimean Congo Hemorrhagic Fever (CCHF) is the life-threatening disease caused by Nairovirus of genus Bunya virus caused by tick bite of Hayalomma species or by direct contact of the blood/sera of the patient and animals suffering from this disease. Epidemics have been occurring in Balochistan province of Pakistan and neighboring Afghanistan and Iran from time to time with this mortality. Aim: In the absence of facilities for detection of serological markers of CCHF (IgM Et IgG antibodies and PCR for viral RNA), a study was designed to diagnose and treat cases of CCHF reporting to a specialist unit hospital situated at Quetta, Pakistan. The aim was to compare the clinical features, complications and outcome of both groups of patients: one detecting the disease clinically only and the other depending upon serological tests for the diagnosis. Methods: Thirty-four patients having fever of less than two weeks of duration with features of bleeding from the skin and various orifices were included in this study from June 2001 to September 2001 after hospitalization. Index case and some of the consecutive cases were subjected to detection of serological markers. Rest of the cases were diagnosed on clinical ground and baseline laboratory investigations only. Difference in both the group was noted carefully. All the patients were given Ribavirin and blood products as and when required. Results: Statistically there was no obvious difference in clinical manifestations (fever, body aches, purpuric spots, ecchymosis, epistaxis, gum bleed etc. ) and laboratory findings (blood picture, serum ALT, serum urea and electrolytes, PT, APTT, etc). There was also no difference in mortality of the two groups studied. Conclusion: In an on ongoing outbreak of CCHF, history, clinical findings and supportive baseline, laboratory investigations may be sufficient for early detection and treatment of CCHF cases. However for documentation of start of epidemic, serological markers should be done

    HIV-associated Kaposi sarcoma (KS) is one of the most common malignancies in sub-Saharan Africa. The diagnosis is often based on clinical suspicion, without histopathologic confirmation. When biopsies are performed, the accuracy of interpretation by local pathologists is poorly understood. We assessed the accuracy of clinical suspicion and pathologic diagnosis of KS in 2 East African countries. At 2 large HIV care sites in Uganda and Kenya, we evaluated consecutive biopsies performed from October 2008 to January 2013 on HIV-infected adults with clinically suspected KS. Biopsies were interpreted by both local African pathologists and a group of US-based dermatopathologists from a high volume medical center. For the purpose of this analysis, the US-based dermatopathologist interpretation was used as the gold standard. Positive predictive value was used to characterize accuracy of local African clinical suspicion of KS, and concordance, sensitivity, and specificity were used to characterize accuracy of local pathologic diagnosis. Among 1106 biopsies, the positive predictive value of clinical suspicion of KS was 77% (95% confidence interval: 74% to 79%). When KS was not histopathologically diagnosed, clinically banal conditions were found in 35%, medically significant disorders which required different therapy in 59% and life-threatening diseases in 6%. Concordance between African pathologists and US-based dermatopathologists was 69% (95% confidence interval: 66% to 72%). Sensitivity and specificity of African pathologic diagnoses were 68% and 89%, respectively. Among East African HIV-infected patients, we found suboptimal positive predictive value of clinical suspicion of KS and specific, but not sensitive, histopathologic interpretation. The findings call for abandonment of isolated clinical diagnosis of KS in the region and augmentation of local dermatopathologic services.

    Vestibular neuritis is one of the most common peripheral causes of acute vestibular syndrome, of which the diagnosis is generally based on a comprehensive interpretation of clinical and laboratory findings following reasonable exclusion of other disorders. This study aimed to investigate the final diagnosis of patients admitted to hospital under the clinical impression of vestibular neuritis who showed no unilateral caloric paresis. Forty-five patients who visited the emergency department with isolated acute spontaneous vertigo were included. Among them, six patients (13%) developed definitive spontaneous vertigo lasting longer than 20min again after discharge from hospital, accompanied by hearing loss, which was audiometrically documented, leading to a final diagnosis of definite Ménière's disease. Nine patients (20%) revisited our clinic with recurrent episodic vertigo without any documented hearing loss or auditory symptoms such as hearing loss, tinnitus or ear fullness, which led to a final diagnosis of possible Ménière's disease. In four patients (9%), initial spontaneous vertigo and nystagmus changed to positional vertigo and nystagmus on the second hospital day. In 26 patients (58%), neither another episode of vertigo nor auditory symptoms developed during follow-up period (7-92months), a condition to which the authors gave an arbitrary diagnosis of "mild unilateral vestibular deficit". In conclusion, patients admitted to hospital under clinical impression of vestibular neuritis may have various final diagnoses, and "mild unilateral vestibular deficit" was the most common final diagnosis among patients who did not meet the diagnostic criteria of vestibular neuritis.

    Early diagnosis through newborn screening (NBS) and early treatment of cystic fibrosis (CF) do lead to better prognosis. In the Netherlands, the median age for a clinical diagnosis is six months, and after newborn screening this is 30 days. It is unknown if being diagnosed at the age of six months or before two months leads to a clinically relevant difference of the clinical condition at the time of diagnosis. The aim of this study is to assess the differences in clinical parameters at diagnosis between children with CF identified by newborn screening (NBS) or by clinical diagnosis (CD) in the Netherlands. From July 1st, 2007 to January 1st, 2012 all newly diagnosed CF patients were reported to the Dutch Paediatric Surveillance Unit (DPSU). All paediatricians received a questionnaire to collect data on mutations and clinical condition at diagnosis. Non-classical CF was excluded from the analysis on clinical condition. 204 new CF diagnoses were reported to the DPSU, 33 were reported twice and three had no CF after further testing. 127 questionnaires were returned (76%); 85 children were diagnosed because of clinical symptoms, 40 after NBS and two because of a positive family history. The median age at diagnosis was 34 weeks for a clinical diagnosis and 3 weeks after NBS. Non-classical CF was more prevalent in the NBS group (6 clinical, 14 NBS), mostly F508del/R117H7T (12). Compared to the NBS group, significantly more patients in the CD group showed failure to thrive, respiratory symptoms, and hospitalizations. 62% of the CD group showed abnormal signs at physical examination compared to 4% of the NBS group. At the time of diagnosis infants detected after NBS are in a significantly better condition than after a clinical diagnosis. Growth retardation is already seen when after NBS the diagnosis is confirmed, but NBS leads to a diagnosis before respiratory symptoms have developed. Copyright © 2014 Elsevier Inc.

    Allergic Rhinitis is a universal common disease, especially in populated cities and urban areas. Diagnosis and treatment of Allergic Rhinitis will improve the quality of life of allergic patients. Though skin tests remain the gold standard test for diagnosis of allergic disorders, clinical experts are required for accurate interpretation of test outcomes. This work presents a clinical decision support system (CDSS) to assist junior clinicians in the diagnosis of Allergic Rhinitis. Intradermal Skin tests were performed on patients who had plausible allergic symptoms. Based on patient׳s history, 40 clinically relevant allergens were tested. 872 patients who had allergic symptoms were considered for this study. The rule based classification approach and the clinical test results were used to develop and validate the CDSS. Clinical relevance of the CDSS was compared with the Score for Allergic Rhinitis (SFAR). Tests were conducted for junior clinicians to assess their diagnostic capability in the absence of an expert. The class based Association rule generation approach provides a concise set of rules that is further validated by clinical experts. The interpretations of the experts are considered as the gold standard. The CDSS diagnoses the presence or absence of rhinitis with an accuracy of 88.31%. The allergy specialist and the junior clinicians prefer the rule based approach for its comprehendible knowledge model. The Clinical Decision Support Systems with rule based classification approach assists junior doctors and clinicians in the diagnosis of Allergic Rhinitis to make reliable decisions based on the reports of intradermal skin tests.

    In this review, we focus on the clinical features, diagnosis and management of pneumococcal pneumonia in HIV-infected and noninfected patients, with particular attention to the most recent advances in this area. Classical clinical features are found in young adults, whereas atypical forms occur in immunocompromised patients including HIV-infected individuals. Bacteremic pneumococcal pneumonia is more frequently observed in HIV-infected and also in low-risk patients, according to the Pneumonia Severity Index (PSI). Pneumococcal pneumonia diagnostic process includes physical examination, radiologic findings and microbiologic diagnosis. However, etiologic diagnosis using traditional culture methods is difficult to obtain. In this setting, urinary antigen test, which recognizes Streptococcus pneumoniae cell wall C-polysaccharide, increases the probability of etiologic diagnosis. A correct management approach is crucial in reducing pneumococcal pneumonia mortality. The use of the PSI helps clinicians in deciding between inpatient and outpatient management in immunocompetent individuals, according to Infectious Diseases Society of America (IDSA)-American Thoracic Society (ATS) guidelines. Recent findings support PSI utility also in HIV-infected patients. Recently, efficacy of pneumococcal vaccine in reducing pneumococcal disease incidence has been evidenced in both HIV-infected and noninfected individuals. Rapid diagnosis and correct management together with implementation of preventive measures are crucial in order to reduce pneumococcal pneumonia related incidence and mortality in HIV-infected and noninfected patients.

    Demographic and clinical factors may influence assessment of autism symptoms. This study evaluated these correlates and also examined whether social communication and interaction and restricted/repetitive behavior provided unique prediction of autism spectrum disorder diagnosis. We analyzed data from 7352 siblings included in the Interactive Autism Network registry. Social communication and interaction and restricted/repetitive behavior symptoms were obtained using caregiver-reports on the Social Responsiveness Scale. Demographic and clinical correlates were covariates in regression models predicting social communication and interaction and restricted/repetitive behavior symptoms. Logistic regression and receiver operating characteristic curve analyses evaluated the incremental validity of social communication and interaction and restricted/repetitive behavior domains over and above global autism symptoms. Autism spectrum disorder diagnosis was the strongest correlate of caregiver-reported social communication and interaction and restricted/repetitive behavior symptoms. The presence of comorbid diagnoses also increased symptom levels. Social communication and interaction and restricted/repetitive behavior symptoms provided significant, but modest, incremental validity in predicting diagnosis beyond global autism symptoms. These findings suggest that autism spectrum disorder diagnosis is by far the largest determinant of quantitatively measured autism symptoms. Externalizing (attention deficit hyperactivity disorder) and internalizing (anxiety) behavior, low cognitive ability, and demographic factors may confound caregiver-report of autism symptoms, potentially necessitating a continuous norming approach to the revision of symptom measures. Social communication and interaction and restricted/repetitive behavior symptoms may provide incremental validity in the diagnosis of autism spectrum disorder. PMID:24104512

    Coeliac disease is characterised by an increased mortality mostly due to its complications. To study the risk of developing complications according to clinical presentation and age at diagnosis, a combined retrospective-prospective longitudinal study was performed in three Italian centres. Incidence of complications and mortality rates were calculated using type and age at diagnosis of coeliac disease, sex, and centre of diagnosis as predictors. Patients referred after being found to suffer from coeliac disease elsewhere were excluded. Between 01/1999 and 06/2015, 2225 adult coeliac patients were directly diagnosed in our centres. 17 of them developed a complication and 29 died. In patients older than 60 years at diagnosis of coeliac disease, the risk of complication is 18 times higher than in patients diagnosed at 18-40 years and 9 times higher than in patients diagnosed at 40-60 years. Classical presentation increases the risk of complications by 7 times compared to non-classical presentation; in asymptomatic patients the risk of complication is virtually absent. The risk of developing complications in coeliac patients is linked to age at diagnosis of coeliac disease and type of clinical presentation. Follow-up methods of coeliac patients should be tailored according to these parameters. Copyright © 2017. Published by Elsevier Ltd.

    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.

    Full Text Available Background: TSH receptor antibody (TRAb is considered the gold standard diagnostic test for the autoimmunity of Graves’ disease (GD, which is commonly diagnosed clinically. Aim: To evaluate the true positive (sensitivity and true negative (specificity rates of clinical diagnosis of GD or non-GD hyperthyroidism compared to the TRAb test. Setting: University teaching hospital in North West England. Participants: Patients in the Endocrinology service who had a TRAb measurement between December 2009 and October 2015. Methods: Electronic patient records were studied retrospectively for a pre-TRAb clinical diagnosis of GD or non-GD hyperthyroidism. We examined descriptive statistics and binary classification tests; Fisher exact test was used to analyse contingency tables. Results: We identified 316 patients with a mean age of 45 (range, 17–89 years; 247 (78% were women. Compared to the TRAb result, clinical diagnosis had a sensitivity of 88%, specificity 66%, positive predictive value 72%, negative predictive value 84%, false negative rate 12%, false positive rate 34%, positive likelihood ratio 2.6 and negative likelihood ratio 0.2 (P < 0.0001. Conclusions: Clinicians were liable to both over- and under-diagnose GD. The TRAb test can help reduce the number of incorrect or unknown diagnoses in the initial clinical assessment of patients presenting with hyperthyroidism.

    To identify specific clinical and epidemiological parameters for clinical diagnosis of SFTSV infection with relatively higher accuracy. 231 suspected cases of SFTS were reported by various medical institutions from 2011 to 2013 in Jiangsu Province, China. They were followed with SFTSV diagnosis tests and interview-administered questionnaires about demographic characteristics, clinical symptoms and epidemiological exposure factors. Univariate and multivariable logistic regression analysis were used to examine the diagnostic value of these parameters. SFTSV infection occurred only from April to October annually and usually in hilly areas of specific regions. Three prediction models of SFTSV infection were constructed. Model 3 with clinical and epidemiological parameters combined the benefits of both Model 1and Model 2, which was optimal and had an overall accuracy of 80.2%. Independent indicators for clinical diagnosis of SFTSV infection in Model 3 were as follows: lymphadenopathy (P = 0.01), leucopenia (P50 years (P = 0.01), tick bites (Pdiagnosis as differentiating SFTSV infection from SFTS-like diseases, thus reducing the risk of misdiagnosis.

    Urine is the most frequent specimen received for culture/sensitivity by clinical laboratories. The microbiological performance of HiCrome UTI agar medium was compared with Blood agar and MacConkey agar for isolation and presumptive identification of bacteria from urine culture. A total of 443 consecutively collected midstream and/or catheter-catch urine samples from patients attending the Islami Bank Medical College Hospital, Rajshahi, Bangladesh during January to December, 2012 were cultured. Urine samples showing pus cells ≥ 5/HPF were inoculated on to Blood agar (BA), MacConkey agar (MAC) and HiCrome UTI agar (CA) media simultaneously and incubated overnight aerobically at 37(0)C. Rate of isolation and presumptive identification of bacterial species were compared for different media. Culture yielded a total of 199 bacterial isolates from 189 (42.67%) positive plates including 179 (40.40%) unimicrobial and 10 (2.26%) polymicrobial (mixed growth of pair of bacteria) growths. Both HiCrome UTI agar and Blood agar media supported 100% growths while 151 (75.88%) growths were observed on MacConkey agar. The rate of presumptive identification was found significantly higher on HiCrome UTI agar (97.49%) than MAC agar (67.34%) (P<0.001) as primary urine culture medium. Of 199 isolates, E. coli was found to be the leading uropathogen isolated from 118 (59.30%) samples with its presumptive identification rate of 95.76%, 93.22% and 5.93% on CA, MAC and BA respectively. All 10 (100%) polymicrobial growths were demonstrated distinctly on CA against only 01(10%) on each BA and MAC. HiCrome UTI agar was found to be more useful as primary urine culture medium in both higher rate of isolation and presumptive identification of uropathogens in comparison to conventional media. Its inherent characteristics in demonstrating polymicrobial growth and ease of rapid identification by distinct colony colour are unique.

  12. 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.

    Contrast enhanced ultrasound (CEUS) technology has made important developments over the past decade. It has been applied in the clinical diagnosis for various diseases of multiple organs including liver, kidney, thyroid, breast and so on, which greatly improves the accuracy of ultrasound diagnosis. The emergence of targeted ultrasound microbubble makes ultrasound molecular imaging possible. More than the improvement of ultrasound imaging, microbubble contrast agent also could be an effective drug or gene carrier. Microbubble will rupture under the irradiation effect of local ultrasound, and then the carried drugs or genes will be released to achieve the purpose of targeted therapy. We should pay more attention on the progress of ultrasound microbubble contrast technology in clinical and basic research. It will promote better understanding and clinical applications of this novel medical ultrasound technology.

    Ischaemic stroke clinical outcomes are improved by earlier treatment with intravenous thrombolysis. An existing pathway at the Mater University Hospital for assessment of suspected acute stroke in the Emergency Department was updated, aiming to shorten ‘door to needle time’. This study examines the final clinical diagnosis of Dublin Fire Brigade Ambulance Paramedic identified Face Arm Speech Test (FAST) positive patients presenting to the Emergency Department over a 7 month period. A retrospective analysis was carried out of 177 consecutive FAST positive patients presenting between March and November 2014. The final clinical diagnosis was acute stroke in 57.1% (n=101) of patients. Of these, 76 were ischaemic strokes of whom 56.5% (n=43) were thrombolysed. In the pre-hospital setting Ambulance Paramedics can identify, with reasonable accuracy, acute stroke using the FAST test. Over half of the ischaemic stroke patients presenting via this pathway can be treated with intravenous thrombolysis

    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

    Full Text Available Background. Obstetrics and gynecological conditions (OB-GYNc are difficult to be differentiated from appendicitis in young adult females presenting with acute lower abdominal pain. Timely and correct diagnosis is clinically challenging. Method. A retrospective data analysis was performed on 542 female patients who were admitted to a tertiary care hospital with a chief complaint of acute lower abdominal pain. Diagnostic indicators of appendicitis and OB-GYNc were identified by stepwise multivariable polytomous logistic regression. Diagnostic performances of the scores were tested. Result. The developed clinical score is comprised of (1 guarding or rebound tenderness, (2 pregnancy, (3 sites of abdominal tenderness, (4 leukocytosis, (5 peripheral neutrophils ≥75%, and (6 presence of diarrhea. For diagnosis of appendicitis, the area under the ROC curve was 0.8696, and the sensitivity and specificity were 89.25% and 70.00%. For OB-GYNc, the corresponding values were 0.8450, 66.67%, and 94.85%, respectively. Conclusion. The clinical scoring system can differentiate the diagnosis of acute lower abdominal pain in young adult females. Time spent for diagnosis at the emergency room may be shortened, and the patients would be admitted to the appropriate departments in less time.

    Valid and reliable diagnosis of posttraumatic stress disorder is important for clinical practice, scientific research and forensic settings. The aim of the study was to assess the psychometric properties of the Polish version of SCID-I F Module for the diagnosis of PTSD. Five hundred twenty six motor vehicle accident survivors participated in the study. Clinical diagnosis was based on SCID-I-PTSD interview. Participants filled out a set of self-report inventories concerning PTSD symptoms (PDS), depression (BDI-II), anxiety (STAI) and posttraumatic cognitions (PTCI). The interview assessment showed high reliability and both convergent and discriminative validity. SCID-I-PTSD interview proved to be more specific than PDS inventory. Interview items show good psychometric properties (except an item C3) and no differential item functioning for sex. Latent structure analysis of PTSD symptoms were nonconclusive. A part of Module F of the SCID-I, a structured clinical interview for the assessment of posttraumatic stress disorder is a valid and reliable psychometric tool useful for the diagnosis of PTSD.

    Desquamative gingivitis is an elucidating term used to demonstrate epithelial desquamation, erythema, erosions, and/or vesiculobullous lesions of the gingiva. Detection and differentiation between conditions that manifest desquamative gingivitis have been almost a continuing problem for dental undergraduates. Several studies have described the association between desquamative gingivitis and other relevant conditions. This study aimed to review the current literature on desquamative gingivitis and to formulate a clinical guide for the differential diagnosis of desquamative gingivitis designated as a teaching aid tool for dental undergraduates. A search strategy based on the key words "desquamative gingivitis, guidelines, diagnosis, undergraduate, teaching" was performed in Medline and Google Scholar. Papers published between 1932 and December 2014 were scrutinized. Only articles that describe the terminology and classification of DG-associated disorders or the diagnostic procedures of DG were selected, then obtained in full text and analyzed. 47 studies were included and reviewed narratively. The clinical signs and symptoms of desquamative gingivitis are insufficient to make a definitive diagnosis. We proposed a clinical flowchart aimed to help dental undergraduates achieving their goal in making an accurate and easy diagnosis. However, this guideline needs further evaluation.

    Cystic fibrosis (CF) can be difficult to diagnose, even when newborn screening (NBS) tests yield positive results. This challenge is exacerbated by the multitude of NBS protocols, misunderstandings about screening vs diagnostic tests, and the lack of guidelines for presumptive diagnoses. There is also confusion regarding the designation of age at diagnosis. To improve diagnosis and achieve standardization in definitions worldwide, the CF Foundation convened a committee of 32 experts with a mission to develop clear and actionable consensus guidelines on diagnosis of CF with an emphasis on screened populations, especially the newborn population. A comprehensive literature review was performed with emphasis on relevant articles published during the past decade. After reviewing the common screening protocols and outcome scenarios, 14 of 27 consensus statements were drafted that apply to screened populations. These were approved by 80% or more of the participants. It is recommended that all diagnoses be established by demonstrating dysfunction of the CF transmembrane conductance regulator (CFTR) channel, initially with a sweat chloride test and, when needed, potentially with newer methods assessing membrane transport directly, such as intestinal current measurements. Even in babies with 2 CF-causing mutations detected via NBS, diagnosis must be confirmed by demonstrating CFTR dysfunction. The committee also recommends that the latest classifications identified in the Clinical and Functional Translation of CFTR project [http://www.cftr2.org/index.php] should be used to aid with CF diagnosis. Finally, to avoid delays in treatment, we provide guidelines for presumptive diagnoses and recommend how to determine the age of diagnosis. Copyright © 2016. Published by Elsevier Inc.

    Wernicke's encephalopathy is an acute neuropsychiatric syndrome resulting from thiamine deficiency, which is associated with significant morbidity and mortality. According to autopsy-based studies, the disorder is still greatly underdiagnosed in both adults and children. In this review, we provide an update on the factors and clinical settings that predispose to Wernicke's encephalopathy, and discuss the most recent insights into epidemiology, pathophysiology, genetics, diagnosis, and treatment. To facilitate the diagnosis, we classify the common and rare symptoms at presentation and the late-stage symptoms. We emphasise the optimum dose of parenteral thiamine required for prophylaxis and treatment of Wernicke's encephalopathy and prevention of Korsakoff's syndrome associated with alcohol misuse. A systematic approach helps to ensure that patients receive a prompt diagnosis and adequate treatment.

    Full Text Available Febrile illnesses that are caused by malaria and other infectious diseases are a major cause of morbidity and mortality in sub-Saharan Africa. In malaria endemic countries, malaria is considered as one of the most serious febrile illnesses. Over the last two decades, major investment in malaria control has witnessed a major achievement in decline of malaria burden, however, other causes of febrile illnesses have remained prevalent. The decline in malaria burden poses challenges for the diagnosis of malaria in clinical settings, research and disease surveillance. This review highlights the challenges facing the diagnosis of malarial and nonmalarial fevers under reduced malaria burden from the perspectives of parasite diagnosis and interpretations of the diagnoses of malarial and non-malarial fevers, and the possible approaches to address the challenges for a better understanding of the dynamics of febrile illnesses under reduced malaria burden.

    Full Text Available The review presents the data of recent studies dealing with cognitive impairments (CI in patients with Parkinson's disease (PD and gives their characteristics and epidemiology, the specific features of the pathogenesis and clinical manifestations, as well as current methods for their diagnosis and treatment. Moderate CIs (MCIs occur in 18.9–55% of patients with PD; the prevalence of dementia during a cross-sectional study approaches 30%. The 2007 Movement Disorder Society criteria and algorithm for the diagnosis of dementia in PD and the 2012 criteria and the algorithm for the diagnosis of MCIs allow one to maximally accurately identify these disorders. Only rivastigmine is now recognized as effective in treating CI in PD and recommended for use. Overall, therapies for CI in PD have been inadequately investigated, making it necessary to conduct further large-scale studies.

    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...

    The objective of this article is to compare the diagnosis of menstrual migraine without aura (MM) from a clinical interview with prospective headache diaries in a population-based study. A total of 237 women with self-reported migraine in at least half of menstruations were interviewed by a neurologist about headache and diagnosed according to the International Classification of Headache Disorders II (ICHD II). Additionally, the MM criteria were expanded to include other types of migraine related to menstruation. Subsequently, all women were asked to complete three month prospective headache diaries. A total of 123 (52%) women completed both clinical interview and diaries. Thirty-eight women were excluded from the analyses: Two had incomplete diaries and 36 women recorded ≤1 menstruation, leaving 85 diaries eligible for analysis. Sensitivity, specificity, positive and negative predictive value and Kappa for the diagnosis of MM in clinical interview vs. headache diary were 82%, 83%, 90%, 71% and 0.62 (95% CI 0.45-0.79). Using a broader definition of MM, Kappa was 0.64 (95% CI 0.47-0.83). A thorough clinical interview is valid for the diagnosis of MM. When this is undertaken, prospective headache diaries should not be mandatory to diagnose MM but may be necessary to exclude a chance association. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Background: Mechanical low back pain (L.B.P is most common in middle-aged people especially in developing countries and the symptom compromises routine life activities of the patients. Disk herniation is the most frequent cause of LBP. The less costly way for diagnosing the cause of LBP is performing a careful physical examinations. This study aimed to evaluate the sensitivity and specificity of clinical diagnosis of the cause of Discal Sciatic Neuralgia at Construction Labors in comparison to MRI as the gold standard. Methods: In a descriptive- analytic study 60 middle-aged professional construction workers were evaluated. Their age range was 25-45 years old and all of them had the complaint of mechanical LBP. Medical history was taken and all cases under went a cautious physical examination. The presence of disk herniation between L4-L5 orL5-S1 was recorded according to clinical signs and symptoms. Lumbosacral MRI was performed for all cases and the results were compared to clinical data. Results: The clinical diagnosis of presence and severity of pathology was confirmed by MRI in all stages of discopathy in L5-S1 and L4-L5 vertebrae (sensitivity= 100%. Conclusion: This study showed that careful physical examinations will be sufficient for the sciatic neuralgia diagnosis and even the staging of disk herniation can be performed clinically. Requesting MRI as an expensive procedure is not recommended for diagnosis of Discal sciatic neuralgia because of feasibility of the cost effective way of precise physical examination.

    Percutaneous needle core biopsies are routinely performed for renal mass diagnosis in some institutions. Because of limited tissue availability, accurate diagnosis can be challenging, and the role of needle core biopsy (NCB) remains debatable in kidney tumor management. In the present study, we reported our experience in diagnosing renal masses via percutaneous NCB and the role it plays in clinical management of these masses. We studied 301 consecutive cases of percutaneous NCBs performed for 280 renal masses from 269 patients between year 2008 and 2011 by reviewing final pathology diagnosis, hematoxylin and eosin slides, and ancillary studies. Diagnostic accuracy was determined by comparing biopsy and nephrectomy diagnoses in a subset of renal masses. Clinical data including demographic information, clinical presentation, radiographic findings, and treatment information were reviewed subsequently if available. The size of renal masses in our study cohort ranged from 0.5 to 24 cm, and 78% of them were small renal masses. Definite diagnoses were rendered in 89% of the renal masses by NCBs, and 23% of them were benign. Renal mass NCB was 100% accurate in diagnosing primary renal malignancy and 93% accurate in determining histologic subtypes. Clinical management was analyzed for 180 renal masses. There was significant difference in clinical management between different diagnostic groups. We conclude that percutaneous NCB is a powerful tool not only for definite tissue diagnosis of renal masses before treatment but also plays an important role in guiding patient management and obtaining material for future molecular studies for targeted therapies.

  9. The development of an evidence-based clinical checklist for the diagnosis of anterior knee pain

    Directory of Open Access Journals (Sweden)

    Dominique C. Leibbrandt

    2017-03-01

    Full Text Available Background: Anterior knee pain (AKP or patellofemoral pain syndrome is common and may limit an individual’s ability to perform common activities of daily living such as stair climbing and prolonged sitting. The diagnosis is difficult as there are multiple definitions for this disorder and there are no accepted criteria for diagnosis. It is therefore most commonly a diagnosis that is made once other pathologies have been excluded. Objectives: The aim of this study was to create an evidence-based checklist for researchers and clinicians to use for the diagnosis of AKP. Methods: A systematic review was conducted in July 2016, and an evidence-based checklist was created based on the subjective and objective findings most commonly used to diagnose AKP. For the subjective factors, two or more of the systematic reviews needed to identify the factor as being important in the diagnosis of AKP. Results: Two systematic reviews, consisting of nine different diagnostic studies, were identified by our search methods. Diagnosis of AKP is based on the area of pain, age, duration of symptoms, common aggravating factors, manual palpation and exclusion of other pathologies. Of the functional tests, squatting demonstrated the highest sensitivity. Other useful tests include pain during stair climbing and prolonged sitting. The cluster of two out of three positive tests for squatting, isometric quadriceps contraction and palpation of the patella borders and the patella tilt test were also recommended as useful tests to include in the clinical assessment. Conclusion: A diagnostic checklist is useful as it provides a structured method for diagnosing AKP in a clinical setting. Research is needed to establish the causes of AKP as it is difficult to diagnose a condition with unknown aetiology.

    2011-01-01

    to clarify the reliability of two clinical meniscal tests, McMurray's and Apley's and the MRI imaging, in order to establish how to reduce unjustified arthroscopies. 102 patients were selected out of 160. All patients were submitted to a triple clinical examination (by a young surgeon and two skilled surgeons), MRI and an arthroscopic procedure. The investigated clinical tests were McMurray's and Apley's test. The positivity or negativity of the tests and MRI were compared to arthroscopic findings. Arthroscopy is considered the gold standard for the diagnosis of meniscal lesions. We measured the length of the meniscal lesions in order to correlate it to the clinical findings. From the clinical examination, we got the following data: McMurray's test: sensitivity 79.7%, specificity 78.5%, accuracy 79.4%, positive likelihood ratio 3.7, negative likelihood ratio 0.2. Apley's test: sensitivity 83.7%, specificity 71.4%, accuracy 80.3%, positive likelihood ratio 2.9, negative likelihood ratio 0.2. The composite assessment is strictly dependent on how the discordance of the two tests is evaluated. The assessment of the clinical tests was done even in relation to medial or lateral meniscal lesion. No statistical difference was found about the length of the meniscal tear. MRI gave the following results: sensitivity 78.3%, specificity 85.7%, accuracy 80.3%. If we use, as diagnostic means, McMurray's and Apley's clinical tests and MRI as imaging procedure, we have an accuracy of about 80%. It is important to keep in mind that it is not possible to have the absolute certainty of make a correct diagnosis in case of meniscal lesions. Patients, too, have to be informed about the risk of a negative arthroscopy.

    A rapid enzymatic two-step test for the presumptive differentiation of four Candida species commonly occurring in various clinical samples is described. The technique involves membrane filtration of a liquid sample, followed by preincubation of the membrane filter on Sabouraud glucose agar supplemented with ticarcillin-clavulanic acid to yield microcolonies. In a separate assay step, parts of the filter are placed on absorbent pads impregnated with fluorogenic 4-methylumbelliferyl (4-MU) enzyme substrates (4-MU-N-acetyl-beta-D-galactosaminide, 4-MU-phosphate, 4-MU-pyrophosphate, and 4-MU-beta-D-galactoside) in combination with 0.1% digitonin acting as a membrane permeabilizer. The membrane filter in contact with the assay medium is incubated to allow cleavage of the enzyme substrate, resulting in fluorescent microcolonies under long-wavelength UV light. This approach, tested on 301 clinical samples, is able to presumptively differentiate C. albicans, C. glabrata, C. krusei, and C. tropicalis and to distinguish them from other Candida spp. in about 9 to 11 h. Overall agreement with the conventional methods of 94.4% (one Candida species present in the sample) to 83.8% (multiple Candida spp. present) was obtained. The false-negative rates with reference to identification by traditional methods were 1.3% (single species) and 3.8% (multiple species).

    To characterize the fracture pattern and the clinical history at the time of diagnosis of osteogenesis imperfecta. In this retrospective study, all patients with osteogenesis imperfecta, of both genders, aged 0-18 years, who were treated between 2002 and 2014 were included. Medical records were assessed to collect clinical data, including the presence of blue sclerae, dentinogenesis imperfecta, positive familial history of osteogenesis imperfecta, and the site of the fractures. In addition, radiographic findings at the time of the diagnosis were reviewed. Seventy-six patients (42 females) were included in the study. Individuals' age ranged from 0 to 114 months, with a median (interquartile range) age of 38 (6-96) months. Blue sclerae were present in 93.4% of patients, dentinogenesis imperfecta was observed in 27.6% of patients, and wormian bones in 29.4% of them. The number of fractures at diagnosis ranged from 0 to 17, with a median of 3 (2-8) fractures. Forty (57%) patients had fractures of the upper and lower extremities, and 9 patients also had spinal fractures. The diagnosis was performed at birth in 85.7% of patients with type 3, and 39.3% of those with type 4/5 of the disorder. Osteogenesis imperfecta is a genetic disorder with distinctive clinical features such as bone fragility, recurrent fractures, blue sclerae, and dentinogenesis imperfecta. It is important to know how to identify these characteristics in order to facilitate the diagnosis, optimize the treatment, and differentiate osteogenesis imperfecta from other disorders that also can lead to fractures.

    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.

    Restless legs syndrome (RLS) is a distressing condition with an impact on various aspects of an individual's life. However, the condition is underrecognized due to a lack of awareness and the fact that the patient does not describe symptoms easily associated with RLS. In clinical practice, the main misdiagnoses are the following: circulation problems, venous diseases, arthritis, back or spinal injury. It is possible to make a diagnosis of RLS based on the patient's medical history and physical examination, in conjunction with the essential criteria of International RLS Study Group (IRLSSG). If the patient fulfils each of the four criteria, a diagnosis of RLS is likely. Supportive features (including response to a dopaminergic agent, and positive family history for RLS) as well as associated features (natural clinical course, sleep disturbance, normal findings on physical examination) are not necessary for a diagnosis to be made but may support the diagnosis in ambiguous cases. In most conditions that may be confused with RLS (sleep starts, nocturnal leg cramps, neuroleptic-induced akathisia, painful leg and moving toe syndrome), RLS can be excluded for the lack of response to the dopaminergic treatment, as well as for the lack of the typical circadian profile.

    The aim of this study is to assess the opinions of relatives about telling the lung cancer diagnosis to the patient and evaluate the implementation in our hospital. A survey questionnaire was designed, and applied on nurses and physicians working in oncology care units, 4th-6th grade medical students, and relatives of cancer and non-cancer patients. Totally 347 (228 males, 119 females) participants (64 physicians, 100 nurses, 61 medical students, and 122 relatives of patients) with a mean age of 28 were enrolled in the study. 62.5% of doctors, 53.2% of nurses, 59.5% of medical students and 45.9% of relatives of lung cancer patients thought that the patient should be informed about his/her cancer diagnosis. 29.5% of the physicians told their patients about their diagnosis of cancer. Gender, age, abroad experience, academic career, speciality, and period of professional experience were not determined to have any impact on physician's opinion and clinical practices. It was determined that physicians care more about patients' right to be informed than other participating groups. Generally, although physicians agree that the diagnosis of cancer should be told to the patient, their routine clinical practices do not reflect this viewpoint.

    Full Text Available Rett syndrome represents one of the most important neuropsychiatric genetic diseases. It affects generally girls with the incidence 1:10000–1:15000. Mutations in clinked gene mecp2 are considered as the main cause of the disease. The particular patterns of chromosome x replication (type C are observed in affected females allowing the cytogenetic technique application for the diagnosis. Cytogenetic and molecular genetic studies carried out in the present work allowed us to propose an integrated approach for the diagnosis of this disease. A clinical description, cytogenetic analyses (assessment of an abnormal chromosome X replication type in affected females as well as chromosome complement abnormalities in affected males, molecular cytogenetic assays using DNA probes specific for mecp2 gene region, studying mecp2 mutations, and x chromosome inactivation pattern studies were combined in order to provide the efficient clinical and genetic diagnosis of RTT as well as counseling of family with affected children. The data obtained have shown to increase significantly the efficiency of the diagnosis as well as genetic counseling of families with Rett syndrome affected children.Key words: Rett syndrome, x-chromosome inactivation, mecp2 mutations, replication of chromosome x, children.

    Clinical analysis and genetic testing of a family with osteogenesis imperfecta type IV were conducted, aiming to discuss antenatal genetic diagnosis of osteogenesis imperfecta type IV. Preliminary genotyping was performed based on clinical characteristics of the family members and then high-throughput sequencing was applied to rapidly and accurately detect the changes in candidate genes. Genetic testing of the III5 fetus and other family members revealed missense mutation in c.2746G>A, pGly916Arg in COL1A2 gene coding region and missense and synonymous mutation in COL1A1 gene coding region. Application of antenatal genetic diagnosis provides fast and accurate genetic counseling and eugenics suggestions for patients with osteogenesis imperfecta type IV and their families.

  19. Palatal radicular groove: Clinical implications of early diagnosis and surgical sealing

    2011-01-01

    Full Text Available Palatal radicular groove is a discreet alteration in tooth morphology, characterized by an invagination that begins near the cingulum of the tooth and moves in an apical direction. Clinically, palatal radicular groove may be associated with periodontal and/or endodontic problems. This paper describes a clinical case of a young patient with palatal radicular groove with no signs of periodontal disease or endodontic impairment. An early diagnosis was made and treatment consisted of surgical sealing of the defect. After a 2-year period, reexaminations demonstrated adequate hygiene, maintenance of tooth vitality and periodontal health. The early diagnosis and sealing of the groove observed surgically made the root surface smooth, avoiding subgingival bacterial plaque buildup, and preventing possible periodontal and/or pulp impairment stemming from the defect.

    Comparison of clinical and paraclinical parameters as tools for early diagnosis of classical swine fever. Louise Lohse, Åse Uttenthal, Jens Nielsen. National Veterinary Institute, Division of Virology, Lindholm, Technical University of Denmark. Introduction: In order to limit the far-reaching socio......-economic as well as the animal welfare consequences of an outbreak of classical swine fever (CSF), early diagnosis is essential. However, host-virus interactions strongly influence the course of CSF disease, and the clinical feature is not clear, thus complicating the diagnostic perspective.

    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.

    2016-01-01

    Full Text Available True placenta accreta is the attachment of chorionic villi to the myometrium, possibly penetrating into the thickness of the myometrium and its outside, including through the serous tunic. The main current diagnostic techniques are considered to be ultrasonography, laboratory diagnosis (elevated human chorionic gonadotropin and placental lactogen levels, and clinical data (pain and vaginal discharge. Magnetic resonance imaging is deemed to be an adjuvant technique. By using a clinical example, this paper considers the capabilities of magnetic resonance imaging to diagnose this abnormality and to choose a right treatment policy. The abnormality is compared with the conditions (trophoblastic tumor and myoma with lysis that are similar in their diagnosis and magnetic resonance pattern. The disorder in question is rather rare and its detailed consideration, determination of the capabilities of various techniques, and comparison with externally similar cases areimportant for the development of diagnostic opportunities.

    Full Text Available Abstract Background Neck pain (NP is a common cause of disability. Accurate and efficacious methods of diagnosis and treatment have been elusive. 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 guide in applying 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 NP. Methods Demographic, diagnostic and baseline outcome measure data were gathered on a cohort of NP patients examined by one of three examiners trained in the application of the DBCDG. Results Data were gathered on 95 patients. Signs of visceral disease or potentially serious illness were found in 1%. Centralization signs were found in 27%, segmental pain provocation signs were found in 69% and radicular signs were found in 19%. Clinically relevant myofascial signs were found in 22%. Dynamic instability was found in 40%, oculomotor dysfunction in 11.6%, fear beliefs in 31.6%, central pain hypersensitivity in 4%, passive coping in 5% and depression in 2%. 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, oculomotor dysfunction, poor coping and depression, correlations and patterns among the diagnostic components of the DBCDG as well as inter-examiner reliability, validity and efficacy of treatment based on the DBCDG.

    Full Text Available Diagnosis of ankylosing spondylitis is based on characteristic clinical picture of the disease and mandatory identification of sacroiliitis on pelvis X-ray. However, case reports of the radiographic stages of sacroiliac joint disorder available in literature are less informative and often lead to misinterpretation of radiographic changes. Based on many years of experience, the authors present the extended explanations of standard radiographic stages of sacroiliitis and other radiological signs that can facilitate diagnostic search in ankylosing spondylitis.

    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

    PSP is a neuropathologically defined disease entity. Clinical diagnostic criteria, published in 1996 by the National Institute of Neurological Disorders and Stroke/Society for PSP, have excellent specificity, but their sensitivity is limited for variant PSP syndromes with presentations other than Richardson's syndrome. We aimed to provide an evidence- and consensus-based revision of the clinical diagnostic criteria for PSP. We searched the PubMed, Cochrane, Medline, and PSYCInfo databases for articles published in English since 1996, using postmortem diagnosis or highly specific clinical criteria as the diagnostic standard. Second, we generated retrospective standardized clinical data from patients with autopsy-confirmed PSP and control diseases. On this basis, diagnostic criteria were drafted, optimized in two modified Delphi evaluations, submitted to structured discussions with consensus procedures during a 2-day meeting, and refined in three further Delphi rounds. Defined clinical, imaging, laboratory, and genetic findings serve as mandatory basic features, mandatory exclusion criteria, or context-dependent exclusion criteria. We identified four functional domains (ocular motor dysfunction, postural instability, akinesia, and cognitive dysfunction) as clinical predictors of PSP. Within each of these domains, we propose three clinical features that contribute different levels of diagnostic certainty. Specific combinations of these features define the diagnostic criteria, stratified by three degrees of diagnostic certainty (probable PSP, possible PSP, and suggestive of PSP). Clinical clues and imaging findings represent supportive features. Here, we present new criteria aimed to optimize early, sensitive, and specific clinical diagnosis of PSP on the basis of currently available evidence. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    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.)

    2017-10-01

    Factor VII (FVII) deficiency is a rare inheritable bleeding disorder affecting 1/500 000 individuals. Clinical manifestations are heterogeneous, from asymptomatic to severe and potentially fatal bleeding. These clinical manifestations do not correlate well with FVII plasma levels. For this reason, FVII-deficient patient management during surgery or for long-term prophylaxis remains challenging. Laboratory testing for FVII activity is, however, the first-line method for FVII deficiency diagnosis and is helpful for managing patients in combination with clinical history. Additional testing consists of FVII immunoassay and genetic testing. Genetic abnormalities on the FVII gene are heterogeneous and can translate into quantitative or qualitative defects. Some of the latter can react differently with different thromboplastins; this can be misleading for the laboratory as no consensus exists at present on an FVII deficiency diagnosis methodology. Indeed, no single test is able to predict accurately the bleeding risk. This review provides a broad picture of inherited and acquired FVII deficiency with a particular focus on laboratory diagnosis.

    To describe the frequency of the nonhomologous end-joining factor 1 (NHEJ1) mutation and the compliance between clinical and genetic diagnosis of choroidal hypoplasia (CH) in a group of Norwegian Border Collies. Border collie puppies in the age from 5 to 8 weeks. Puppies included in the study had a complete ophthalmological examination. All findings were recorded, and an ECVO scheme form was issued for each puppy. DNA samples were achieved from buccal swabs. Genetic typing was performed for the 7.8-kb deletion in the gene encoding NHEJ1. Dogs with none, one, or two copies of the mutated allele were classified as free, carriers, and affected, respectively. 103 Border Collie puppies from 16 litters, 52 females and 51 males, were included in the study. Ages ranged from 5.1 to 8.9 weeks. One puppy had clinical findings consistent with CH and optic nerve coloboma compatible with the diagnosis Collie Eye Anomaly (CEA). Findings on ophthalmological examination of the remaining puppies were within normal limits. On genetic testing, 85 puppies were clear of the mutation in the NHEJ1 gene, 17 puppies were carriers, and one puppy was genetically affected. A good compliance between the clinical diagnosis and the genetic test results was found in all of the puppies examined. The allele frequency of the mutation was 6.3%. © 2017 American College of Veterinary Ophthalmologists.

    2016-09-01

    Kawasaki disease is an acute, self-limited vasculitis of childhood and has become the leading cause of acquired pediatric heart disease in the USA. Prompt treatment is essential in reducing cardiac-related morbidity and mortality. The underlying etiology remains unknown. The disease itself may be the characteristic manifestation of a common pathway of immune-mediated vascular inflammation in susceptible hosts. The characteristic clinical features of fever for at least 5 days with bilateral nonpurulent conjunctivitis, rash, changes in lips and oral cavity, changes in peripheral extremities, and cervical lymphadenopathy remain the mainstay of diagnosis. Supplementary laboratory criteria can aid in the diagnosis, particularly in cases of incomplete clinical presentation. Diagnosis of Kawasaki disease can be challenging as the clinical presentation can be mistaken for a variety of other pediatric illnesses. Standard of care consists of intravenous immune globulin and aspirin. Corticosteroids, infliximab, and cyclosporine A have been used as adjunct therapy for Kawasaki disease refractory to initial treatment. There is ongoing research into the use of these agents in the initial therapy of Kawasaki disease.

    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 {sup 32}P 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.

    The carpal boss reflects an osseous protuberance at the level of the dorsal base of the second or third metacarpal, variably present in the general population. There are numerous theories as to the etiology of the bony excrescence; however, the exact cause remains uncertain. The abnormality can result in dorsal wrist pain and swelling. The diagnosis is typically established based on clinical examination and imaging, including radiography, ultrasound, nuclear medicine, computed tomography, and magnetic resonance imaging. We review the proposed theories of how the carpal boss develops, explain the clinical manifestations, demonstrate the imaging appearance, and address treatment strategies.

    When approaching a patient with suspected motor neuron disease (MND), the pattern of weakness on examination helps distinguish MND from other diseases of peripheral nerves, the neuromuscular junction, or muscle. MND is a clinical diagnosis supported by findings on electrodiagnostic testing. MNDs exist on a spectrum, from a pure lower motor neuron to mixed upper and lower motor neuron to a pure upper motor neuron variant. Amyotrophic lateral sclerosis (ALS) is a progressive mixed upper and lower motor neuron disorder, most commonly sporadic, which is invariably fatal. This article describes a pattern approach to identifying MND and clinical features of sporadic ALS. Copyright © 2015 Elsevier Inc. All rights reserved.

    2003-03-01

    Proliferative osseous lesions usually found in the external ear are exostoses and osteomata. In other sites they are clearly different entities, but in this location histopathologic differential features are not so reliable in the study of the specimens. An occlusive osteomata is shown, with the typical clinical presentation demonstrated in a multiplanar CT. Microscopically, the lesion consisted of mature bone trabeculae, separated by medular spaces with fibrovascular tissue, characteristic features of osteomata. However, in the most superficial areas, lines of bone apposition, like those in exostoses, were found. A literature review confirms the lack of specificity of the histopathologic study, so diagnosis is based on clinical data.

    Through the retrospective analysis of the clinical data in 14 cases of invasive fungal rhinosinusitis (IFRS), the clinical characteristics, diagnosis and treatment of this disease were evaluated. Fourteen clinically confirmed cases of IFRS since January 2008 to October 2015 were evaluated.collected, the clinical features, diagnosis, treatment and prognosis were analyzed to obtain a more comprehensive understanding for clinical reference. Fourteen patients were confirmed by pathological examination as IFRS, including 9 cases of aspergillus, 4 cases of mucor, and 1 case of rhinocerebral zygomycosis; including 5 cases of acute IFRS, 9 cases of chronic IFRS. All patients were treated with endoscopic surgery and intravenous antifungal therapy. Nine cases of chronic IFRS (including 1 case of mucor, 7 cases of aspergillus and 1 case of rhinocerebral zygomycosis) were cured, but the vision loss, diplopia or blindness, hard palate perforation remained. Five cases of acute IFRS included 3 cases of mucor and 2 cases of aspergillus. Among the 3 cases of mucor, 2 cases were died and 1 case was cured. Among the 2 cases of aspergillus, 1 patient was cured and the other patient died of electrolyte disorder after discharge from hospital. Patients with IFRS usually have diabetes. After the active surgical cleaning of lesion tissue and the systematic antifungal treatment with adequate dosage, these patients would have a better result. IFRS caused by mucor is ofen dangerous.

    Duchenne and Becker muscular dystrophy (DMD/BMD) are X-linked recessive disorders caused by mutation in dystrophin gene. We reported 3-year clinic experience from a single hospital in Shanghai using multiplex ligation dependent probe amplification (MLPA) assay to detect DMD mutations. Four hundred and fifty-one males and 184 females, who were clinically diagnosed as DMD/BMD patients or carriers at our hospital's outpatient clinic, were collected and performed with MLPA to detect DMD gene mutations. Seventeen novel mutation points not reported in the Leiden Muscular Dystrophy pages were identified in this study. We found that the most frequent deletion spots ranged from exon45 to exon52, and exon2, exon19 were the two most frequently detected duplication spots. The results of our study confirmed MLPA as an efficient clinical method for detecting DMD gene mutations in DMD/BMD patients. Single exon mutation detected by MLPA should be verified by other methods, and we should emphasize that only precise clinical molecular diagnosis can lead to the feasibility of prenatal diagnosis. © 2014 Wiley Periodicals, Inc.

    The aim of this study is to analyze the increasing need of radiological support in the diagnosis of acute appendicitis (AA), the clinical repercussions associated, and the parameters of diagnostic accuracy of ultrasound and computed tomography (CT) scan for AA. Observational and analytical study. Cohort, patients operated on for suspected AA at a tertiary referral hospital. Pregnancy and <14 years were exclusion criteria. January 2010-December 2011 (n1=419). set of patients aged 18 to 65 years old operated between October 2001-September 2003 (n2=237). Variables analyzed in both groups: 1) percentage of radiological support for diagnosis of acute appendicitis; 2) sensitivity and positive predictive value (PPV) of ultrasound and CT scan; 3) rate of surgical explorations with negative result or with diagnosis other than acute appendicitis. SPSS software, χ(2) test, statistical significance accepted with P<.05, 95% confidence interval (95% CI) for the odds ratio (OR). Age, gender, percentage of atypical locations and gangrenous/perforated episodes were similar in both groups. The number of radiological examinations needed for diagnosis was significantly higher in the study group (78.8% vs. 30.4%, P<.0,000). Sensitivity was significantly superior for CT than for ultrasound scan (97% vs. 86%), but PPV was similar in both tests (92% vs. 94%). Surgical exploration percent values with diagnosis of acute appendicitis was significantly higher in the study group (94.5% vs. 88.6%; P<.006, OR 2.2; CI 95% 1.25-4). CT and ultrasound scan are excellent diagnostic tools for acute appendicitis, and have contributed to a significant increase in surgical explorations with correct diagnosis. Copyright © 2012 AEC.

    Classic pituitary apoplexy (PA) is an acute, life-threatening clinical syndrome caused by acute hemorrhage and/or infarction of the pituitary gland. PA is considered a neuroendocrinological emergency. However, there is no consensus about the best options for PA diagnosis and management. To develop a clinical practice guideline with a number of recommendations for diagnosis and treatment of patients with PA based on the medical evidence available, in order to help clinicians involved in their care. The clinical guideline for diagnosis and treatment of pituitary apoplexy issued in 2006 by the Neuroendocrinology Working Group of the Spanish Society of Endocrinology and Nutrition (SEEN) and the British Clinical Practice Guideline published in 2011 were taken as the basis. The text has been adapted to the format used in most international medical journals. For this, after updated medical literature, the quality of evidence and the strength of the recommendations were evaluated using the system proposed by the Agency for Health Care Policy and Research (AHCPR). Diagnosis of pituitary apoplexy should be considered in all patients with acute severe headache with or without neuro-ophthalmic signs. Patients with PA must undergo a complete history and physical examination. All patients with suspected pituitary apoplexy should have urgent blood samples drawn to test electrolytes, renal function, liver function, coagulation screen, complete blood count, and basal levels of pituitary and peripheral hormones, and to rule out adrenocorticotropic hormone (ACTH) deficiency. Formal visual field assessment should be performed when the patient is clinically stable. Magnetic resonance imaging (MRI) is the imaging test of choice to confirm diagnosis. Indications for empirical urgent corticosteroid therapy in patients with PA include hemodynamic instability, impaired consciousness, reduced visual acuity, and severe visual field defects. In patients with these severe neuro-ophthalmic signs

    ‘Masked hypertension’ is defined as having non-elevated clinic blood pressure (BP) with elevated out-of-clinic average BP, typically determined by ambulatory BP monitoring. Approximately 15–30% of adults with non-elevated clinic BP have masked hypertension. Masked hypertension is associated with increased risks of cardiovascular morbidity and mortality compared to sustained normotension (non-elevated clinic and ambulatory BP), which is similar to or approaching the risk associated with sustained hypertension (elevated clinic and ambulatory BP). The confluence of increased cardiovascular risk and a failure to be diagnosed by the conventional approach of clinic BP measurement makes masked hypertension a significant public health concern. However, many important questions remain. First, the definition of masked hypertension varies across studies. Further, the best approach in the clinical setting to exclude masked hypertension also remains unknown. It is unclear whether home BP monitoring is an adequate substitute for ambulatory BP monitoring in identifying masked hypertension. Few studies have examined the mechanistic pathways that may explain masked hypertension. Finally, scarce data are available on the best approach to treating individuals with masked hypertension. Herein, we review the current literature on masked hypertension including definition, prevalence, clinical implications, special patient populations, correlates, issues related to diagnosis, treatment, and areas for future research.

    Background Many factors have been mentioned as contributing to under-diagnosis and under-reporting of zoonotic diseases particularly in the sub-Sahara African region. These include poor disease surveillance coverage, poor diagnostic capacity, the geographical distribution of those most affected and lack of clear strategies to address the plight of zoonotic diseases. The current study investigates the knowledge of medical practitioners of zoonotic diseases as a potential contributing factor to their under-diagnosis and hence under-reporting. Methods The study was designed as a cross-sectional survey. Semi-structured open-ended questionnaire was administered to medical practitioners to establish the knowledge of anthrax, rabies, brucellosis, trypanosomiasis, echinococcosis and bovine tuberculosis in selected health facilities within urban and rural settings in Tanzania between April and May 2005. Frequency data were analyzed using likelihood ratio chi-square in Minitab version 14 to compare practitioners' knowledge of transmission, clinical features and diagnosis of the zoonoses in the two settings. For each analysis, likelihood ratio chi-square p-value of less than 0.05 was considered to be significant. Fisher's exact test was used where expected results were less than five. Results Medical practitioners in rural health facilities had poor knowledge of transmission of sleeping sickness and clinical features of anthrax and rabies in humans compared to their urban counterparts. In both areas the practitioners had poor knowledge of how echinococcosis is transmitted to humans, clinical features of echinococcosis in humans, and diagnosis of bovine tuberculosis in humans. Conclusion Knowledge of medical practitioners of zoonotic diseases could be a contributing factor to their under-diagnosis and under-reporting in Tanzania. Refresher courses on zoonotic diseases should be conducted particularly to practitioners in rural areas. More emphasis should be put on zoonotic

    Accurate recognition of stroke symptoms by Emergency Medical Services (EMS) is necessary for timely care of acute stroke patients. We assessed the accuracy of stroke diagnosis by EMS in clinical practice in a major US city. Philadelphia Fire Department data were merged with data from a single comprehensive stroke center to identify patients diagnosed with stroke or TIA from 9/2009 to 10/2012. Sensitivity and positive predictive value (PPV) were calculated. Multivariable logistic regression identified variables associated with correct EMS diagnosis. There were 709 total cases, with 400 having a discharge diagnosis of stroke or TIA. EMS crew sensitivity was 57.5% and PPV was 69.1%. EMS crew identified 80.2% of strokes with National Institutes of Health Stroke Scale (NIHSS) ≥5 and symptom duration 270 min (OR 0.41, 95% CI 0.25-0.68). EMS dispatchers identified 90 stroke cases that the EMS crew missed. EMS dispatcher or crew identified stroke with sensitivity of 80% and PPV of 50.9%, and EMS dispatcher or crew identified 90.5% of patients with NIHSS ≥5 and symptom duration <6 h. Prehospital diagnosis of stroke has limited sensitivity, resulting in a high proportion of missed stroke cases. Dispatchers identified many strokes that EMS crews did not. Incorporating EMS dispatcher impression into regional protocols may maximize the effectiveness of hospital destination selection and pre-notification.

    The study presented in this paper formed the first part of a large survey of breast cancer patients in one health authority in England, UK looking at individual needs expressed by women with a diagnosis of breast cancer. The paper provides an account of the experiences of 12 women with a diagnosis of breast cancer. The women represent a wide age range and different stages of illness. The transcribed accounts of the women were analysed by means of Qualitative Solutions and Research, Non-Numerical Unstructured Data Indexing Searching and Theorising (QSR*NUDIST). The study examined the individual experiences of women with a diagnosis of breast cancer and its aftermath as they passed through different stages related to it. The women's experiences are presented within the conceptual framework of the clinical pathway and their accounts represent their journey along the pathway. Various significant points in this journey are portrayed representing the women's reactions to diagnosis, treatment, femininity and body image, support, family and friends, information and after care.

    Full Text Available Alertness to dengue and making a timely diagnosis is extremely important in the treatment of dengue and containment of dengue epidemics. We evaluated the complementary role of clinical-practice-based laboratory data in facilitating suspicion/diagnosis of dengue. One hundred overall dengue (57 dengue fever [DF] and 43 dengue hemorrhagic fever [DHF] cases and another 100 nondengue cases (78 viral infections other than dengue, 6 bacterial sepsis, and 16 miscellaneous diseases were analyzed. We separately compared individual laboratory variables (platelet count [PC] , prothrombin time [PT], activated partial thromboplastin time [APTT], alanine aminotransferase [ALT], and aspartate aminotransferase [AST] and varied combined variables of DF and/or DHF cases with the corresponding ones of nondengue cases. The sensitivity, specificity, accuracy, positive predictive value (PPV, and negative predictive value (NPV in the diagnosis of DF and/or DHF were measured based on these laboratory variables. While trade-off between sensitivity and specificity, and/or suboptimal PPV/NPV was found at measurements using these variables, prolonged APTT + normal PT + PC < 100 × 109 cells/L had a favorable sensitivity, specificity, PPV, and NPV in diagnosis of DF and/or DHF. In conclusion, these data suggested that prolonged APTT + normal PT + PC < 100 × 109 cells/L is useful in evaluating the likelihood of DF and/or DHF.

    Adrenoleukodystrophy disorder is one of the x-linked genetic disorders caused by the myelin sheath breakdown in the brain. In this study, we present 4 yr experience on this disorder. The patients diagnosed as adrenoleukodystrophy in the Neurology Department of Mofid Children's Hospital in Tehran, Iran from 2010 to 2014 were enrolled into the study. The disorder was confirmed by neuroimaging and clinical findings along with genetic and neurometabolic assessment at Reference Laboratory in Germany. We assessed age, gender, past medical history, developmental status, clinical manifestations, and neuroimaging findings of populous family with adrenoleukodystrophy. All of the patients were one populous family with high rate of consanguineous marriages. This disorder was confirmed by genetic assessment, VLCFA and brain MRI. c.253_254insC, p.R85Pfs112* was found in heterozygote state and the VLCFA assessment showed the typical pattern for adrenoleukodystrophy/ adrenomyeloneuropathy. This diagnosis was in agreement with the family history and the clinical history of the patient. Since there have been a number of cases in patient's family in the past, so intensive follow-up on the family especially detection the female members of the family of childbearing age was recommended. The amount of C-26, C24/C22 and C26/C22 was elevated. All patients with the same genotype had wide ranges of clinical presentation. Early diagnose of this disease might help us for early intervention and prenatal diagnosis for the disease in next siblings.

    This pilot study attempts to quantify the benefits of a documented radiographic clinical history through the use of the clinical history template form designed by Egan and Baird. Six radiographers completed the clinical history template for 40 patients and four radiologists included the recorded information as part of their reporting process. A focus discussion group was held between the radiographers to ascertain the level of satisfaction and benefits encountered with the use of the template form. A questionnaire was designed for the radiologists to complete regarding the usefulness of the template form with respect to the radiological reporting process. Results/Discussion: 15 cases for which the form was used demonstrated a direct benefit in respect to improved radiographic clinical decision-making. Radiographers agreed the template form aided the establishment of a stronger radiographer-patient relationship during the radiographic examination. Two radiologists agreed the form aided in establishing a radiological diagnosis and suggested the form be implemented as part of the standard departmental protocol. Despite the small sample size, there is evidence the form aided radiographic decision-making and assisted in the establishment of an accurate radiological diagnosis. The overall consensus amongst radiographers was that it enhanced radiographer-patient communication and improved the level of patient care. Copyright (2004) Australian Institute of Radiography

    Until recently ovarian carcinoma was considered to be a single disease, and treatment decisions were based solely on grade and pre- and postoperative tumour burden. New insights into molecular features, treatment response, and patient demographics led the scientific community to conclude that ovarian carcinoma histotypes are different disease entities. In 2002, the pathology specimens from patients in a clinical trial were reviewed by an experienced gynaecopathologist (pathologist A) for translational research purposes. All cases were typed according to what were then current criteria. The identical cohort was now reassessed by the same expert pathologist and independently reviewed by another gynaecopathologist (pathologist B) applying WHO 2014 diagnostic criteria. Survival analyses were done based on the original as well as the new diagnoses, and historical biomarker study results were recalculated. Upon re-review, pathologist A rendered the same histotype diagnosis in only 54% of cases. In contrast, pathologists A and B independently rendered the same diagnosis in 98% of cases. Histotype was of prognostic significance when 2014 diagnoses were used, but was not prognostic using the original (2002) histotype diagnoses. Our study demonstrates a marked shift in ovarian carcinoma histotype diagnosis over the past 15 years. The new criteria are associated with a very high degree of interobserver reproducibility, allowing for treatment decisions based on histotype. Finally, biomarkers of putative prognostic significance were revealed to be primarily histotype-specific markers, confirming the critical importance of obtaining up-to-date diagnoses rather than accepting archival histotype data in clinical research.

    2015-11-01

    Synopsis The hallmark features of patellar tendinopathy are (1) pain localized to the inferior pole of the patella and (2) load-related pain that increases with the demand on the knee extensors, notably in activities that store and release energy in the patellar tendon. While imaging may assist in differential diagnosis, the diagnosis of patellar tendinopathy remains clinical, as asymptomatic tendon pathology may exist in people who have pain from other anterior knee sources. A thorough examination is required to diagnose patellar tendinopathy and contributing factors. Management of patellar tendinopathy should focus on progressively developing load tolerance of the tendon, the musculoskeletal unit, and the kinetic chain, as well as addressing key biomechanical and other risk factors. Rehabilitation can be slow and sometimes frustrating. This review aims to assist clinicians with key concepts related to examination, diagnosis, and management of patellar tendinopathy. Difficult clinical presentations (eg, highly irritable tendon, systemic comorbidities) as well as common pitfalls, such as unrealistic rehabilitation time frames and overreliance on passive treatments, are also discussed.

    To determine the diagnostic accordance between histopathological and direct immunofluorescence diagnosis of patients with autoimmune vesiculobullous skin diseases. The term pemphigus refers to a group of autoimmune blistering diseases mediated by auto-antibodies directed against desmoglein proteins. The differentiation between the various bullous diseases is important for treatment and prognosis. Direct immunofluorescence microscopy is still the gold standard in differentiating these diseases. Patients with clinical diagnosis of vesiculobullous dermatitis from pemphigus group were included in the study. We retrospectively analyzed histopathologic and direct immunofluorescence results from skin or mucosal samples over 15-year period. 81 patients were included. The accordance was good in pemphigus vulgaris and pemphigus herpetiformis, but low in pemphigus vegetans, pemphigus foliaceus and pemphigus erythematosus. No accordance was in Hailey-Hailey disease and Grover´s disease. Uncommon result in our analysis included: intraepidermal IgG and IgM depositions at DIF in one Grover´s disease patient. Our results confirmed the relevance of direct immunofluorescence assays as a necessary diagnostic method for the definitive diagnosis of autoimmune blistering disease in the case, where the clinical feature and the results of histopathology are not clear (Tab. 4, Fig. 5, Ref. 26).

    To investigate the clinical manifestations, diagnosis, etiology, management, and outcomes of patients with systemic lupus erythematosus (SLE) and pericarditis The authors retrospectively reviewed the records of 81 patients who were diagnosed of SLE according to the American College of Rheumatology criteria and had 82 episodes of pericarditis between 2002 and 2010. The diagnosis of pericarditis was defined as the presence of pericardial effusion alone by echocardiography or having 2 out of 4 of the following criteria: retrosternal pain, pericardial friction rub, widespread ST-segment elevation, and new/worsening pericardial effusion. Most of them (92%) were female with the median disease duration (range) of 1 (0-312) month. Cardiac tamponade occurred in 16% (95% CI 8.72-25.58%). There was no statistically significant difference between patients who developed tamponade and those who did not. The causes ofpericarditis included active SLE (93%), and suspected tuberculosis (TB) (5%), with 2% inconclusive. In patients with lupus pericarditis, 71% had other active organ involvement. Most lupus pericarditis patients (79%) had good response to steroid or NSAIDs. Diagnosis of TB pericarditis was made by clinical suspicion without microbiological or pathological evidence. In an endemic area of TB, lupus pericarditis was still the most common cause of pericarditis in SLE. Most patients responded well to steroid.

    The Cardiovascular Autonomic Neuropathy (CAN) Subcommittee of the Toronto Consensus Panel on Diabetic Neuropathy worked to update CAN guidelines, with regard to epidemiology, clinical impact, diagnosis, usefulness of CAN testing, and management. CAN is the impairment of cardiovascular autonomic control in the setting of diabetes after exclusion of other causes. The prevalence of confirmed CAN is around 20%, and increases up to 65% with age and diabetes duration. Established risk factors for CAN are glycaemic control in type 1 and a combination of hypertension, dyslipidaemia, obesity, and glycaemic control in type 2 diabetes. CAN is a risk marker of mortality and cardiovascular morbidity, and possibly a progression promoter of diabetic nephropathy. Criteria for CAN diagnosis and staging are: (1) one abnormal cardiovagal test result identifies possible or early CAN; (2) at least two abnormal cardiovagal test results are required for definite or confirmed CAN; and (3) the presence of orthostatic hypotension in addition to abnormal heart rate test results identifies severe or advanced CAN. Progressive stages of CAN are associated with increasingly worse prognosis. CAN assessment is relevant in clinical practice for (1) diagnosis of CAN clinical forms, (2) detection and tailored treatment of CAN clinical correlates (e.g. tachycardia, orthostatic hypotension, non-dipping, QT interval prolongation), (3) risk stratification for diabetic complications and cardiovascular morbidity and mortality, and (4) modulation of targets of diabetes therapy. Evidence on the cost-effectiveness of CAN testing is lacking. Apart from the preventive role of intensive glycaemic control in type 1 diabetes, recommendations cannot be made for most therapeutic approaches to CAN. Copyright © 2011 John Wiley & Sons, Ltd.

    To determine the clinical utility of a rapid molecular assay for Clostridium difficile infection (CDI) in an acute hospital setting. From March to September 2011, stool specimens from inpatients in two acute hospitals with suspected CDI were tested prospectively by routine cell culture cytotoxin neutralization assay (CCNA), real-time polymerase chain reaction (PCR) using the GeneXpert (Cepheid Inc., Sunnyvale, CA, USA), and a dual testing algorithm [glutamate dehydrogenase (GDH)/toxin enzyme immuno-assay, Premier, Launch Diagnostics, Longfield, UK]. All patients with positive PCR, CCNA or discrepant results were reviewed by a multi-disciplinary team (treating clinician, gastroenterologist, microbiologist and infection control nurse). C. difficile detection rates were 11.7% (PCR), 6% (CCNA) and 13.8% (GDH). Out of 1034 stool specimens included in the study, 974 (94.1%) had concordant CCNA and PCR results. Eighty-nine percent (886/985) had concordant CCNA, PCR and GDH results, and 94.4% (930/985) had concordant GDH and PCR results. Using clinical diagnosis as the reference, PCR had sensitivity of 99.1%, specificity of 98.9%, positive predictive value (PPV) of 91.9% and negative predictive value (NPV) of 99.9%. CCNA on a single sample had sensitivity of 51%, specificity of 99.4%, PPV of 91.9% and NPV of 94.3%. GDH had sensitivity of 83.8%, specificity of 94.5%, PPV of 64.7% and NPV of 97.9%. Almost twice as many patients were positive by PCR compared with CCNA (121 vs 62); 54/59 of those with discrepant results were clinically confirmed as CDI. Rapid diagnosis of CDI using PCR was timely, accurate and correlated well with clinical diagnosis. Copyright © 2014 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

    Full Text Available A ten-year-old neutered female mixed breed dog was referred for pale mucous membrane and acute onset of right prosencephalic clinical signs. Brain magnetic resonance imaging was suggestive for right middle cerebral artery ischemic stroke. Based on cell blood count, serum biochemistry and serologic tests and flow cytometric detection of anti-platelets and anti-red blood cells antibodies, a diagnosis of immunomediated haemolytic anemia associated with thrombocytopenia of suspected immunomediated origin was done. Immunosuppresive therapy with prednisone was started and the dog clinically recovered. Two months later complete normalization of CBC and serum biochemistry was documented. The dog remained stable for 7 months without therapy; then she relapsed. CBC revealed mild regenerative anemia with spherocytosis and thrombocytopenia. A conclusive Evans’ syndrome diagnosis was done and prednisone and cyclosporine treatment led to normalization of physical and CBC parameters. The dog is still alive at the time the paper submitted. Possible thrombotic etiopathogenetic mechanisms are illustrated in the paper and the authors suggest introducing Evans’ syndrome in the differential diagnosis list for brain ischemic stroke in dogs.

    Trichotillomania is a psychodermatologic disorder characterized by uncontrollable urge to pull one's own hair. Differential diagnoses include the most common forms of alopecia such as alopecia areata. It is usually associated with depression and obsessive-compulsive disorder. Trichotillomania treatment standardization is a gap in the medical literature. Recent studies demonstrated the efficacy of N-acetylcysteine (a glutamate modulator) for the treatment of the disease. We report the clinical case of a 12-year-old female patient who received the initial diagnosis of alopecia areata, but presented with clinical and dermoscopic features of trichotillomania. She was treated with the combination of psychotropic drugs and N-acetylcysteine with good clinical response. Due to the chronic and recurring nature of trichotillomania, more studies need to be conducted for the establishment of a formal treatment algorithm.

    Full Text Available BackgroundAccurate recognition of stroke symptoms by Emergency Medical Services (EMS is necessary for timely care of acute stroke patients. We assessed the accuracy of stroke diagnosis by EMS in clinical practice in a major US city.Methods and resultsPhiladelphia Fire Department data were merged with data from a single comprehensive stroke center to identify patients diagnosed with stroke or TIA from 9/2009 to 10/2012. Sensitivity and positive predictive value (PPV were calculated. Multivariable logistic regression identified variables associated with correct EMS diagnosis. There were 709 total cases, with 400 having a discharge diagnosis of stroke or TIA. EMS crew sensitivity was 57.5% and PPV was 69.1%. EMS crew identified 80.2% of strokes with National Institutes of Health Stroke Scale (NIHSS ≥5 and symptom duration <6 h. In a multivariable model, correct EMS crew diagnosis was positively associated with NIHSS (NIHSS 5–9, OR 2.62, 95% CI 1.41–4.89; NIHSS ≥10, OR 4.56, 95% CI 2.29–9.09 and weakness (OR 2.28, 95% CI 1.35–3.85, and negatively associated with symptom duration >270 min (OR 0.41, 95% CI 0.25–0.68. EMS dispatchers identified 90 stroke cases that the EMS crew missed. EMS dispatcher or crew identified stroke with sensitivity of 80% and PPV of 50.9%, and EMS dispatcher or crew identified 90.5% of patients with NIHSS ≥5 and symptom duration <6 h.ConclusionPrehospital diagnosis of stroke has limited sensitivity, resulting in a high proportion of missed stroke cases. Dispatchers identified many strokes that EMS crews did not. Incorporating EMS dispatcher impression into regional protocols may maximize the effectiveness of hospital destination selection and pre-notification.

    2012-01-01

    Background Clinical differential diagnosis between atopic dermatitis and seborrheic eczema is sometimes difficult. Early differential diagnosis is important, since atopic dermatitis can be more difficult to treat and may be associated with asthma and allergic rhinitis. Methods In a cohort study, 96 infants with high risk for atopic dermatitis were followed up from the maternal ward until they completed one year of age. The infants were submitted to complete skin examination, monthly, for a 1 year period. A full skin examination was performed and any sign of eczema was registered. Therapy with hydrocortisone 1% cream was prescribed. Eczema onset time, skin distribution, response to therapy and the presence of pruritus were evaluated. Results 87 (96%) infants fulfilled the study criteria (physical examination at least 10 months). Fivty four (62%) infants had signs of eczema during one year follow up. Atopic dermatitis was diagnosed in 14 (16%) patients and seborrheic eczema in 30 (34.5%) infants, with 10 (11.5%) classified as: both eczemas. Atopic eczema onset was mainly between 2 and 4 months and seborrheic eczema between 1 week and 3 months, with an important coincident period. Facial eczema had similar onset and semiological aspect for both diseases in its beginning. Head eczema was present in 40 (74%) eczema infants, 33 (82.5%) with a posterior diagnosis of seborrheic eczema and 7 (17.5%) with atopic dermatitis. After 3 to 5 months, axillar and groin folds eczema were the main signs of seborrheic dermatitis diagnosis, while face, neck and limbs were the main eczema sites in atopic dermatitis. The 10 infants with dubious eczema just after 6 months could have a more accurate eczema diagnosis. Hanifin et Rajka diagnostic criteria for infants showed to be useful just after 6 months, since some of its criteria are evolutive. All patients improved with hydrocortisone cream, but seborrheic eczema infants had a better response and prognosis, with complete eczema

    Functional Neuroimaging has been traditionally used in research for patients with different Parkinsonian syndromes. However, the emergence of commercial radiotracers together with the availability of single photon emission computed tomography (SPECT) and, more recently, positron emission tomography (PET) have made them available for clinical practice. Particularly, the development of clinical evidence achieved by functional neuroimaging techniques over the past two decades have motivated a progressive inclusion of several biomarkers in the clinical diagnostic criteria for neurodegenerative diseases that occur with Parkinsonism. However, the wide range of radiotracers designed to assess the involvement of different pathways in the neurodegenerative process underlying Parkinsonian syndromes (dopaminergic nigrostriatal pathway integrity, basal ganglia and cortical neuronal activity, myocardial sympathetic innervation), and the different neuroimaging techniques currently available (scintigraphy, SPECT and PET), have generated some controversy concerning the best neuroimaging test that should be indicated for the differential diagnosis of Parkinsonism. In this article, a panel of nuclear medicine and neurology experts has evaluated the functional neuroimaging techniques emphazising practical considerations related to the diagnosis of patients with uncertain origin parkinsonism and the assessment Parkinson's disease progression.

    To determine the usefulness of autopsy findings in the quality improvement of patients care. The clinical and necropsy findings of all the cases, who died in hospital and had undergone autopsy examination at CMH, Kharian, from January 2001 to December 2003, were retrieved from record of clinical case sheet data and autopsy record of the hospital. The two were analyzed and compared according to the discrepancy classification. The exclusion and inclusion criteria, the international classification of disease (ICD) to code deaths, the global burden of disease (GBD) system to classify and group diseases, and the Goldman discrepancy classification to compare clinical and autopsy diagnosis and classify the discrepancies, were used as described. The death rate varied from 0.94% to 1.29% and autopsy rate from 4.69% to 10.10% annually between January 2001 and December 2003. The number of cases classified according to GBD system was 3 (5%) in Group 1, 26 (43.33 %) in Group 2 and 31 (51.66 %) in Group 3. The discrepancy classes included 9 (15 %) class I major discrepancies and 3 (5 %) class II major discrepancies. Non-discrepant diagnosis was seen in 37 cases (61.66 %) and 11 cases (18.32 %) were non classifiable. (author)

    Management of systemic lupus erythematosus (SLE) is complex and variability in practices exists. Guidelines have been developed to help improve the management of SLE patients, but there has been no formal evaluation of these guidelines. This study aims to compare the scope, quality, and consistency of clinical practice guidelines on the diagnosis, monitoring, and treatment of patients with SLE. Electronic databases were searched up to April 2014. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and textual synthesis was used to appraise and compare recommendations. Nine clinical practice guidelines and 5 consensus statements were identified, which covered 7 topics: diagnosis, monitoring, treatment, neuropsychiatric SLE, lupus nephritis, antiphospholipid syndrome, and other manifestations of lupus. The methodological quality of the guidelines was variable, with the overall mean AGREE II scores ranging from 31% to 75%, out of a maximum 100%. Scores were consistently low for applicability, with only 1 guideline scoring above 50%. There was substantial variability in the treatments recommended for class II and V lupus nephritis, the recommended duration of maintenance therapy for class III/IV lupus nephritis (from 1 to 4 years), and timing of ophthalmologic examination for patients taking corticosteroids. Published guidelines on SLE cover a complex area of clinical care, but the methodological quality, scope, and recommendations varied substantially. Collaborative and multidisciplinary efforts to develop comprehensive, high-quality evidence-based guidelines are needed to promote best treatment and health outcomes for patients with SLE. © 2015, American College of Rheumatology.

    Full Text Available OBJECTIVE - Cardiac evaluation (clinical, electrocardiographic and echocardiographic of 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia (FA related to the frequency and the size of GAA repeats (unstable expansion of trinucleotide repeats that results in the disease. METHODS - Clinical and cardiac study including electrocardiogram and echocardiogram of all patients and molecular analysis to detect the frequency and the size of GAA expansion, by polymerase chain reaction analysis. RESULTS - Homozygous GAA expansion was detected in 17 patients (68% -- all typical cases. In 8 (32% cases (6 atypical and 2 typical, no GAA expansion was observed, therefore it was not considered Friedreich's ataxia. All patients with GAA expansion (100% had electrocardiographic abnormalities, and only 25% of the cases without GAA expansion had some abnormality on this exam. However, only 6% of all patients revealed some signals/symptoms suggestive of cardiac involvement. CONCLUSION - A molecular analysis is essential to confirm the diagnosis of Friedreich's ataxia; however, an adequate cardiac evaluation, including an electrocardiogram, was extremely useful to better screening the patients which should perform these molecular analysis.

    This guide aims at providing practitioners taking into care patients presenting a cutaneous cancer with recommendations based on scientific evidences or expert agreements. More precisely, the objectives are to clarify the terminology used to describe the different forms of cutaneous epidermoid carcinoma (CEC) and of their precursors (actinic keratosis, Bowen's disease), to propose a prognosis classification of CECs adapted to the previously identified prognosis factors, to optimise the diagnosis and therapy of actinic keratosis and Bowen's disease according to recent publications, and to recall the principles of a primary prevention of CECs and of their precursors, and of screening of high risk individuals. Thus, the different parts of this report address the following issues: anatomic-clinical forms and epidemiology of CECs and of their precursors, prognosis factors of CECs, means of treatment of CECs and of their precursors (medical, physical, surgical, radiation-based, and chemical treatments). Radiotherapy notably comprises external radiotherapy and interstitial brachytherapy. Indications for radiotherapy are discussed with respect to existing guides and to the clinical situation. The authors address the care of CECs and of their precursors (prevention, screening and clinical diagnosis, care of invasive CECs, keratoacanthoma treatment). They finally discuss quality criteria aimed at practice improvement, and perspectives regarding the evolution of this guide and studies to be performed

  12. Clinical Applications of Hemolytic Markers in the Differential Diagnosis and Management of Hemolytic Anemia.

    Science.gov (United States)

    Barcellini, W; Fattizzo, B

    2015-01-01

    Several hemolytic markers are available to guide the differential diagnosis and to monitor treatment of hemolytic conditions. They include increased reticulocytes, an indicator of marrow compensatory response, elevated lactate dehydrogenase, a marker of intravascular hemolysis, reduced haptoglobin, and unconjugated hyperbilirubinemia. The direct antiglobulin test is the cornerstone of autoimmune forms, and blood smear examination is fundamental in the diagnosis of congenital membrane defects and thrombotic microangiopathies. Marked increase of lactate dehydrogenase and hemosiderinuria are typical of intravascular hemolysis, as observed in paroxysmal nocturnal hemoglobinuria, and hyperferritinemia is associated with chronic hemolysis. Prosthetic valve replacement and stenting are also associated with intravascular and chronic hemolysis. Compensatory reticulocytosis may be inadequate/absent in case of marrow involvement, iron/vitamin deficiency, infections, or autoimmune reaction against bone marrow-precursors. Reticulocytopenia occurs in 20-40% of autoimmune hemolytic anemia cases and is a poor prognostic factor. Increased reticulocytes, lactate dehydrogenase, and bilirubin, as well as reduced haptoglobin, are observed in conditions other than hemolysis that may confound the clinical picture. Hemoglobin defines the clinical severity of hemolysis, and thrombocytopenia suggests a possible thrombotic microangiopathy or Evans' syndrome. A comprehensive clinical and laboratory evaluation is advisable for a correct diagnostic and therapeutic workup of the different hemolytic conditions.

    2016-10-01

    Given the increase in venous thromboembolic events (VTE) in children, the incidence, diagnosis and management of post thrombotic syndrome (PTS) in children is of increasing interest. Current challenges facing clinicians caring for children with VTE is the limited evidence of the long-term outcomes for this cohort; specifically the significance and potential functional impairment associated with PTS. This paper reviews the current evidence to elucidate the risk factors for PTS in children, methods for diagnosis and management of PTS in children (aged less than 18 years). Medline, Cinahl and PsycINFO database searches were undertaken using key search terms. Priority areas in need of further research are highlighted. Expert commentary: The two paediatric PTS assessment tools currently in use have been acknowledged to overcall the incidence of mild PTS in children. A PTS tool's ability to distinguish between clinically significant PTS and mild PTS is crucial. Variation in how PTS has been reported in children across the literature suggests that the real incidence of moderate and /or clinically significant PTS in children is unknown. Furthermore, evidence is lacking about the functional impairment experienced by children with clinically significant PTS and what this means for their long-term health.

    Both pulmonary arterial and peripheral venous sides of venous thromboembolism (VTE) can now be efficiently and safely investigated by multi-detector CT (MDCT) at the same time by a combined CT angiography/CT venography protocol. In the emergency setting, the use of such a single test for patients suspected of suffering from VTE on a clinical grounds may considerably shorten and simplify diagnostic algorithms. The selection of patients to be submitted to MDCT must follow well-established clinical prediction rules in order to avoid generalized referral to CT on a generic clinical suspicion basis and excessive population exposure to increased ionizing radiation dose, especially in young patients. Clinical and anatomical wide-panoramic capabilities of MDCT allow identification of underlying disease that may explain patients' symptoms in a large number of cases in which VTE is not manifest. The analysis of MDCT additional findings on cardiopulmonary status and total thrombus burden can lead to better prognostic stratification of patients and influence therapeutic options. Some controversial points such as optimal examination parameters, clinical significance of subsegmentary emboli, CT pitfalls and/or possible falsely positive diagnoses, and outcome of untreated patients in which VTE has been excluded by MDCT without additional testing, must of course be taken into careful consideration before the definite role of comprehensive MDCT VTE 'one-stop-shop' diagnosis in everyday clinical practice can be ascertained.

    The aim of the study was to analyze the clinical prevalence and pathohistological correlation of dysplastic nevi. In the period between 2000 and 2009, in the Outpatient Clinic of Referral Centre for Melanoma of the Ministry of Health and Social Welfare of the Republic of Croatia, 12,344 patients were examined, and 35.07% of them were surgically removed in the same institution. Among the patients, 69.16% had clinically diagnosed melanocytic tumor. Out of them, 28.39% were dysplastic. Dysplastic nevus was pathohistologically diagnosed in 20.02% of pathohistologically diagnosed melanocytic tumors. There was women predominace among patients with clinically diagnosed dysplastic nevi (65.22%). The most frequent localization was the trunk in both sexes, women 78.18%, men 76.75%. The coincidence of clinical and pathohistological diagnosis of dysplastic nevus was 30.70%. The results of this study, based on a large number of patients could be a significant contribution in understanding characteristics of dysplastic nevus, its clinical and pathohistological complexity. We hope that the data will contribute to the creation of general accepted protocols in the diagnostics of dysplastic nevus.

    Tuberculosis (TB) prevalence surveys offer a unique opportunity to study health seeking behaviour at the population level because they identify individuals with symptoms that should ideally prompt a health consultation. To assess the health-seeking behaviour among individuals who were presumptive TB cases in a national population based TB prevalence survey. A cross sectional survey was conducted between 2013 and 2014 among 66 survey clusters in Zambia. Clusters were census supervisory areas (CSAs). Participants (presumptive TB cases) were individuals aged 15 years and above; having either cough, fever or chest pain for 2 weeks or more; and/or having an abnormal or inconclusive chest x-ray image. All survey participants were interviewed about symptoms and had a chest X-ray taken. An in-depth interview was conducted to collect information on health seeking behaviour and previous TB treatment. Of the 6,708 participants, the majority reported at least a history of chest pain (3,426; 51.1%) followed by cough (2,405; 35.9%), and fever (1,030; 15.4%) for two weeks or more. Only 34.9% (2,340) had sought care for their symptoms, mainly (92%) at government health facilities. Of those who sought care, 13.9% (326) and 12.1% (283) had chest x-ray and sputum examinations, respectively. Those ever treated for TB were 9.6% (644); while 1.7% (114) was currently on treatment. The average time (in weeks) from onset of symptoms to first care-seeking was 3 for the presumptive TB cases. Males, urban dwellers and individuals in the highest wealth quintile were less likely to seek care for their symptoms. The likelihood of having ever been treated for TB was highest among males, urban dwellers; respondents aged 35-64 years, individuals in the highest wealth quintile, or HIV positive. Some presumptive TB patients delay care-seeking for their symptoms. The health system misses opportunities to diagnose TB among those who seek care. Improving health-seeking behaviour among males, urban

    Full Text Available Abstract Background Cockayne syndrome is a rare autosomal recessive neurodegenerative disease characterized by low-to-normal birth weight; growth failure; brain dysmyelination with calcium deposits, cutaneous photosensitivity; pigmentary retinopathy, cataract, and sensorineural hearing loss. To the best of our knowledge, cholestatic liver disease was not previously reported in these patients. Aim To highlight the presence of cholestasis and liver dysfunction in this group of patients and to suggest modified criteria for clinical diagnosis. Methods The study included nine patients with Cockayne from four different families (five males and four females in which Cockayne was suspected clinically. In all patients chromosomal breakage studies revealed mild (45% to moderate (60% increase in frequency of chromatid and chromosome gaps and breaks versus 25% in normal controls. Diagnosis was confirmed by DNA repair assay. Results During routine follow up of these patients, seven of them had evident liver affection ranging from mild elevation in liver enzymes to cholestatic liver disease and liver cell failure. The attacks were recurrent in two patients and were sometimes preceded by infection. The attack may lead to deterioration of neurological and/or liver condition. It may end in liver cell failure that either recovers completely or may lead to death. Conclusions liver disease could be considered common in Egyptian patients with Cockayne with the cholestatic form being the most evident. The syndrome should be included in the list of causes of cholestatic liver disease. Chromosomal breakage study and positive family history should be included as major criteria for clinical diagnosis of Cockayne especially in a population like ours where consanguineous marriage is very high and molecular testing and UV sensitivity tests are considered unaffordable.

    Pixel values in fat/water suppression MRI, and the T1 and T2 relaxation times of skeletal muscles were measured to establish criteria for the clinical MRI diagnosis of neuromuscular diseases. The subjects were 15 patients with a diagnosis of neuromuscular disease based on clinical symptoms and findings made by electrophysiological methods, and 3 patients with hysterical conversion reactions. Normal values were obtained from 33 healthy volunteers. Transaxial MR images of the bilateral thigh muscles were recorded with T1/T2 relaxation time calculation imaging and fat/water suppression imaging (Dixon's method). The patients with muscular dystrophy showed remarkably decreased pixel values in their water images (PV 1) and tremendously increased pixel values in their fat images (PV 2). The finding that T1 became much shorter and T2 slightly longer seemed to be related to the fact that the extent of the increase in PV 2 was relatively greater than that of the decrease in PV 1. The patients with polymyositis showed a PV 1 value that was higher than normal. This finding was quite different from that for muscular dystrophy. As this disease grew worse, the PV 2 increased. The length of T1 seemed to depend on the relationship between PV 1 and PV 2. Prolongation of T2 appeared to be due to increase in PV 2. Both PV 1 and PV 2 in myotonic dystrophy and neurogenic diseases were slightly higher than normal. The patients with polyradiculoneuropathy showed both T1 and T2 relaxation times that were longer than normal. However, the T1 relaxation time in motor neuron diseases had a tendency to become shorter. The parameters in the patients with hysterical conversion reactions remained approximately within normal range. We concluded that measurements of the objective parameters in MRI are useful for the clinical diagnosis of neuromuscular diseases. (author)

    Full Text Available The increased reliability and efficiency of the quantitative polymerase chain reaction (qPCR makes it a promising tool for performing large-scale screening for infectious disease among high-risk individuals. To date, no study has evaluated the specificity and sensitivity of different qPCR assays for leprosy diagnosis using a range of clinical samples that could bias molecular results such as difficult-to-diagnose cases. In this study, qPCR assays amplifying different M. leprae gene targets, sodA, 16S rRNA, RLEP and Ag 85B were compared for leprosy differential diagnosis. qPCR assays were performed on frozen skin biopsy samples from a total of 62 patients: 21 untreated multibacillary (MB, 26 untreated paucibacillary (PB leprosy patients, as well as 10 patients suffering from other dermatological diseases and 5 healthy donors. To develop standardized protocols and to overcome the bias resulted from using chromosome count cutoffs arbitrarily defined for different assays, decision tree classifiers were used to estimate optimum cutoffs and to evaluate the assays. As a result, we found a decreasing sensitivity for Ag 85B (66.1%, 16S rRNA (62.9%, and sodA (59.7% optimized assay classifiers, but with similar maximum specificity for leprosy diagnosis. Conversely, the RLEP assay showed to be the most sensitive (87.1%. Moreover, RLEP assay was positive for 3 samples of patients originally not diagnosed as having leprosy, but these patients developed leprosy 5-10 years after the collection of the biopsy. In addition, 4 other samples of patients clinically classified as non-leprosy presented detectable chromosome counts in their samples by the RLEP assay suggesting that those patients either had leprosy that was misdiagnosed or a subclinical state of leprosy. Overall, these results are encouraging and suggest that RLEP assay could be useful as a sensitive diagnostic test to detect M. leprae infection before major clinical manifestations.

    Background: Squamous cell carcinoma is the most common oral cancer. Early diagnosis ensures better prognosis. Late diagnosis is however common around the world and contributes to the high morbidity and mortality related to oral cancer. The objective of this study was to determine the clinical stage of oral cancer patients at the time of diagnosis. Methods: This retrospective study was carried out on 334 oral cancer patients who presented to the outdoor departments of Armed Forces Institute of Dentistry, and Armed Forces Institute of Pathology, Rawalpindi from July 2008 to December 2009. The records that were reviewed included history and clinical examination findings, OPG and CT scans of the head and neck region, chest X-rays, abdominal ultrasounds and liver function tests. Size of the primary tumour, the size, number and laterality of the involved cervical lymph nodes and the presence/absence of distant metastases were documented and statistically analysed using SPSS-17. Results: Out of the 334 patients, 203 (60.8%) were males and 131 (39.2%) females. The age range was from 21 to 88 years. Buccal mucosa was the most commonly involved site (32 %). The primary tumour was 4 Cm or more in size, (T3/T4) 71.25% of the cases. Cervical lymph nodes were involved in 211 patients (63.2%) and distant metastases were present in 39 patients (11.7%). Overall, clinical stage IV was the most common (57.18%) followed by stage III(24.55%), stage II (13.77%) and stage I (4.49%). Conclusion: Oral cancers are diagnosed late (Stage III and IV) in Pakistan and need immediate public and professional attention. (author)

    Fetal distress has been shown to contribute to the increasing caesarean section rate. There has been controversy on the usefulness of clinical diagnosis of fetal distress using only the intermittent counting of the fetal heart rate and/or passage of meconium-stained liquor. To evaluate the clinical diagnosis of fetal distress and the perinatal outcome. This was a retrospective study in which the case records of the patients, who were diagnosed of fetal distress at Federal Teaching Hospital, Abakaliki, Nigeria, from January 1, 2008 to December 31, 2014, were collated. The statistical analysis was done using the Statistical Package for Social Sciences version 17 software (SPSS Inc., Chicago IL, USA). Out of the 15,640 deliveries carried out within the study period, 3,761 (24.05%) deliveries were through caesarean section. A total of 326 (8.9%) of the 3,761 caesarean sections were due to fetal distress within the study period. More so, a total of 227 (70.9%) babies were born with ≥ 7 Apgar score at the 1(st) minute of delivery. The perinatal mortality rate was 31.25 per 1000 deliveries. Though birth asphyxia was recorded more on babies of mothers that had fresh meconium-stained liquor and whose decision-intervention interval was more than 30 minutes when compared with those without any of the two conditions, there was no statistical significant difference between them. The clinical diagnosis of fetal distress is accurate in 29.1% of the cases. However, it has led to an unnecessary caesarean section in the remaining 70.9% of the parturients. In order to reduce this high trend of unnecessary caesarean sections due to clinical diagnosis of fetal distress in this environment, antepartum fetal assessment with non-stress test or biophysical profile and intrapartum use of continuous electronic fetal monitoring should be used to confirm or refute the fetal distress before any surgical intervention. Fetal blood sampling and fetal pulse oximetry should be performed in event

    Student-run free clinics (SRFCs) are now present at most medical schools. Reports regarding SRFCs have focused on the infrastructure of established clinics, characteristics of the patient populations served, and their contribution to patient care. Few studies discuss their role in preventive medicine and even fewer discuss mental health care. This study examined the outcomes of a medical student-run universal depression screening, diagnosis, and management program at two SRFC sites. Medical students implemented a universal depression screening, diagnosis, and management program within the electronic health record during routine adult primary care visits utilizing the Patient Health Questionnaire-2 (PHQ-2) as an initial screening tool, with a protocol to administer the Patient Health Questionnaire-9 (PHQ-9) if the PHQ-2 score was ≥3. This is a retrospective medical record review of visits from August 13, 2013, through February 13, 2014, to assess this program. Overall, 95.8 % (206/215) of the patients received either the PHQ-2 or the PHQ-9. Among the 174 patients without a previous diagnosis of depression, 166 were screened (95.4 %), of which 33 (19.9 %) had a positive PHQ-2 score of ≥3; 30 (of 33; 90.9 %) appropriately received a PHQ-9. Nineteen (of 166 screened; 11.4 %) previously undiagnosed patients were confirmed to have depression. Fourteen patients had two or more PHQ-9 tests at least 4 weeks apart and eight (57.1 %) had a clinically significant improvement, defined as PHQ-9 score decrease of ≥5. The prevalence of depression diagnosed prior to the implementation of this program in this cohort was 19.1 % (41/215) and after was 27.9 % (60/215). This study demonstrated that medical students with faculty supervision can successfully implement a universal depression screening, diagnosis, and management program at multiple SRFC sites, identify previously undiagnosed depression, and work with interdisciplinary support services to provide treatment options

    Neurocysticercosis has been recognized as a major cause of secondary epilepsy worldwide. So far, most of the knowledge about the disease comes from Latin America and the Indian subcontinent. Unfortunately, in sub-Saharan Africa the condition was neglected for a long time, mainly owing to the lack of appropriate diagnostic tools. This review therefore focuses on the prevalence of neurocysticercosis in sub-Saharan Africa, the clinical picture with emphasis on epilepsy, as well as the diagnosis and treatment of neurocysticercosis and its related epilepsy/epileptic seizures in African resource-poor settings.

    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.

    The provision of psychological support to caregivers is an important part of the role of the clinical staff working in palliative care. Staff knowledge and attitudes may determine their openness to referring caregivers to a psychological intervention. We recently developed a self-help intervention for grief and psychological distress among caregivers and were interested in exploring the extent to which staff knowledge and attitudes might affect future implementation. The aims of our study were to: (1) examine the acceptability of self-help psychological intervention for caregivers among palliative care clinical staff; (2) examine potential attitudinal barriers toward prolonged grief disorder (PGD) as a diagnosis and interventions for grief; and (3) bolster staff confidence in skills and knowledge in identifying and managing caregiver psychological distress. An anonymous survey was distributed among clinical staff at two inpatient units and two community health services that assessed the acceptability of self-help interventions for caregivers, attitudes about PGD diagnosis and grief intervention, and staff confidence in skills and knowledge in assessing caregiver psychological distress. Overall, clinical staff were positively oriented toward self-help for caregivers and intervention for grief. They were also basically confident in their skills and knowledge. While it was positive PGD attitudes that were associated with acceptability of self-help for caregivers, it was both positive and negative PGD attitudes that were associated more specifically with a willingness to refer caregivers to such an intervention. Our findings are useful in highlighting the issues to be considered in the implementation of a self-help intervention within the healthcare service. Clinical staff seemed positively oriented toward engaging with a psychological intervention for caregivers and likely to act as key allies in implementation.

  13. Diagnosis of genital herpes simplex virus infection in the clinical laboratory

    Science.gov (United States)

    2014-01-01

    Since the type of herpes simplex virus (HSV) infection affects prognosis and subsequent counseling, type-specific testing to distinguish HSV-1 from HSV-2 is always recommended. Although PCR has been the diagnostic standard method for HSV infections of the central nervous system, until now viral culture has been the test of choice for HSV genital infection. However, HSV PCR, with its consistently and substantially higher rate of HSV detection, could replace viral culture as the gold standard for the diagnosis of genital herpes in people with active mucocutaneous lesions, regardless of anatomic location or viral type. Alternatively, antigen detection—an immunofluorescence test or enzyme immunoassay from samples from symptomatic patients--could be employed, but HSV type determination is of importance. Type-specific serology based on glycoprotein G should be used for detecting asymptomatic individuals but widespread screening for HSV antibodies is not recommended. In conclusion, rapid and accurate laboratory diagnosis of HSV is now become a necessity, given the difficulty in making the clinical diagnosis of HSV, the growing worldwide prevalence of genital herpes and the availability of effective antiviral therapy.

    The interdependent damage to the heart and kidney organ systems is defined as cardiorenal syndrome, a complex pathophysiological disorder of the heart and kidney in which acute or chronic dysfunction of one organ can lead to acute or chronic damage to the other. Identification and early diagnosis of some subtypes of cardiorenal syndrome very often begin at family physician office, however, the use of simple and reliable diagnostic procedures such as MICE score using ECG and biomarkers has not been implemented yet. The clinical picture, diagnosis and treatment vary according to the 5 cardiorenal syndrome subtypes, as described herein. Rational diagnosis of heart failure at family medicine office should include biomarkers (BNP and NT-pro BNP) before performing ultrasound of the heart, while for kidneys creatinine and estimated glomerular filtration rate are still in use, but not cysteine C and NGAL. Diagnostic procedure for suspected heart failure at family medicine office should include kidney function estimate and vice versa. Access to treatment of cardiorenal syndrome differs depending on the specialty to which the patient is referred first, i.e. consultant examination, cardiologist or nephrologist. A multidisciplinary approach to treatment of cardiorenal syndrome is still lacking.

    Glycogen storage disease (GSD) is an umbrella term for a group of genetic disorders that involve the abnormal metabolism of glycogen; to date, 23 types of GSD have been identified. The nonspecific clinical presentation of GSD and the lack of specific biomarkers mean that Sanger sequencing is now widely relied on for making a diagnosis. However, this gene-by-gene sequencing technique is both laborious and costly, which is a consequence of the number of genes to be sequenced and the large size of some genes. This work reports the use of massive parallel sequencing to diagnose patients at our laboratory in Spain using either a customized gene panel (targeted exome sequencing) or the Illumina Clinical-Exome TruSight One Gene Panel (clinical exome sequencing (CES)). Sequence variants were matched against biochemical and clinical hallmarks. Pathogenic mutations were detected in 23 patients. Twenty-two mutations were recognized (mostly loss-of-function mutations), including 11 that were novel in GSD-associated genes. In addition, CES detected five patients with mutations in ALDOB, LIPA, NKX2-5, CPT2, or ANO5. Although these genes are not involved in GSD, they are associated with overlapping phenotypic characteristics such as hepatic, muscular, and cardiac dysfunction. These results show that next-generation sequencing, in combination with the detection of biochemical and clinical hallmarks, provides an accurate, high-throughput means of making genetic diagnoses of GSD and related diseases.Genet Med 18 10, 1037-1043.

    In-stent restenosis (ISR) is the main limitation of percutaneous coronary interventions (PCI), occurring in approximately 25% of cases. Although frequently asymptomatic, many PCI patients present with recurrent symptoms of chest pain at follow-up raising a clinical suspicion of ISR. The diagnosis of ISR can be challenging in these patients and difficult to rule out without repeat coronary angiography. We prospectively investigated the diagnostic accuracy of clinical evaluation and exercise stress testing to detect ISR as compared to coronary angiography, in a consecutive, unselected cohort of PCI patients. We studied 91 patients with a total of 143 stents. Clinical evaluation predicted ISR to be likely in 19% of cases and the exercise test was positive in 29%. The binary restenosis rate was 21%. Clinical evaluation had a positive predictive value of 29% and accuracy of 71%, while exercise stress testing had a positive predictive value of 19% and accuracy of 65%. In conclusion, we found the diagnostic accuracy of clinical evaluation to be low and not significantly improved by exercise stress testing when evaluating PCI patients for ISR.

    , with 2.2% meeting the UTI definition. Among these, 'clinical diagnosis' correctly identified 46.6% of positive cultures, with 94.7% specificity and an AUROC of 0.77 (95% CI 0.71 to 0.83). Four symptoms, three signs and three dipstick results were independently associated with UTI with an AUROC (95% CI; bootstrap-validated AUROC) of 0.89 (0.85 to 0.95; validated 0.88) for symptoms and signs, increasing to 0.93 (0.90 to 0.97; validated 0.90) with dipstick results. Nappy pad samples were provided from the other 2277 children, of whom 82% were < 2 years old and 1.3% met the UTI definition. 'Clinical diagnosis' correctly identified 13.3% positive cultures, with 98.5% specificity and an AUROC of 0.63 (95% CI 0.53 to 0.72). Four symptoms and two dipstick results were independently associated with UTI, with an AUROC of 0.81 (0.72 to 0.90; validated 0.78) for symptoms, increasing to 0.87 (0.80 to 0.94; validated 0.82) with the dipstick findings. A high specificity threshold for the clean-catch model was more accurate and less costly than, and as effective as, clinical judgement. The additional diagnostic utility of dipstick testing was offset by its costs. The cost-effectiveness of the nappy pad model was not clear-cut. CONCLUSIONS Clinicians should prioritise the use of clean-catch sampling as symptoms and signs can cost-effectively improve the identification of UTI in young children where clean catch is possible. Dipstick testing can improve targeting of antibiotic treatment, but at a higher cost than waiting for a laboratory result. Future research is needed to distinguish pathogens from contaminants, assess the impact of the clean-catch algorithm on patient outcomes, and the cost-effectiveness of presumptive versus dipstick versus laboratory-guided antibiotic treatment.

    Selective immunoglobulin A deficiency (SIgAD) is the most common primary antibody deficiency. Although more patients with SIgAD are asymptomatic, selected patients suffer from different clinical complications such as pulmonary infections, allergies, autoimmune diseases, gastrointestinal disorders and malignancy. Pathogenesis of SIgAD is still unknown; however, a defective terminal differentiation of B cells and defect in switching to IgA-producing plasma cells are presumed to be responsible. Furthermore, some cytogenic defects and monogenic mutations are associated with SIgAD. There is no specific treatment for patients with symptomatic IgA deficiency, although prophylactic antibiotic therapy along with circumstantial immunoglobulin replacement with justification and supportive care (using a product that contains minimal IgA) could be helpful for patients with a severe phenotype. The epidemiology, pathogenesis, clinical phenotype, diagnosis, prognosis, management and treatment in patients with SIgAD have been reviewed. © 2016 The Foundation for the Scandinavian Journal of Immunology.

    Full Text Available Cushing's disease (CD is a rare disorder characterized by the overproduction of adrenocorticotropic hormone due to a pituitary adenoma that ultimately stimulates excessive cortisol secretion from the adrenal glands. Prior to the detection of pituitary adenomas, various clinical signs of CD such as central obesity, moon face, hirsutism, and facial plethora are usually already present. Uncontrolled hypercortisolism is associated with metabolic, cardiovascular, and psychological disorders that result in increased mortality. Hence, the early detection and treatment of CD are not only important but mandatory. Because its clinical manifestations vary from patient to patient and are common in other obesity-related conditions, the precise diagnosis of CD can be problematic. Thus, the present set of guidelines was compiled by Korean experts in this field to assist clinicians with the screening, diagnoses, and treatment of patients with CD using currently available tests and treatment modalities.

    Small-vessel vasculitis is a convenient descriptor for a wide range of diseases characterized by vascular inflammation of the venules, capillaries, and/or arterioles with pleomorphic clinical manifestations. The classical clinical phenotype is leucocytoclastic vasculitis with palpable purpura, but manifestations vary widely depending upon the organs involved. Histopathologic examination in leucocytoclastic vasculitis reveals angiocentric segmental inflammation, fibrinoid necrosis, and a neutrophilic infiltrate around the blood vessel walls with erythrocyte extravasation. The etiology of small-vessel vasculitis is unknown in many cases, but in others, drugs, post viral syndromes, malignancy, primary vasculitis such as microscopic polyarteritis, and connective tissue disorders are associated, The diagnosis of small- vessel vasculitis relies on a thorough history and physical examination, as well as relevant antibody testing including antinuclear antibody and anti neutrophil cytoplasmic antibody, hepatitis B and C serologies, assessment of complement, immunoglobulins, blood count, serum creatinine liver function tests, urinalysis, radiographic imaging and biopsy. The treatment is based primarily on corticosteroid and immunosuppressive agents

    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.

    2009-09-01

    To review the diagnostic criteria for attention-deficit hyperactivity disorder (ADHD), present an overview of the effects that ADHD has on family dynamics, school performance, and substance abuse, and provide an overview of the American Academy of Pediatrics (AAP) clinical practice and treatment guidelines. An extensive health science literature review was carried out using PubMed and Cumulative Index to Nursing and Allied Health Literature. Other information was collected by searching reference lists of published reports. The diagnostic criteria and guidelines are important to make an accurate clinical assessment and manage a child with ADHD. Early diagnosis and treatment of ADHD decreases academic failure, family conflict, social isolation, substance abuse, and occupational adversity in later years for these children. Often primary care nurse practitioners are the first healthcare provider a child with ADHD will see. Awareness of the diagnostic criteria and treatment for children with ADHD can assist with early identification and perhaps eliminate much impairment that accompanies this chronic disorder.

  3. Presumption of Innocence and Public Safety: A Possible Dialogue

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available In Mexico, increasing demands for public safety coupled with the need for a more effective criminal justice system resulted in the security and justice constitutional reform of 2008. The outcome was a constitutional framework with provisions based on the highest standards of human rights on the one hand, and on the other, exceptional measures that restrict rights in an attempt to improve public safety. Unfortunately, the crime rate and incidence of unreported crime have changed little. When public safety is demanded, a clear, rational and concrete response is required. Limiting the alternatives to pre-trial detention or increasing penalties is rarely the appropriate response. This paper focuses on pre-trial detention and non-custodial measures supported by the new criminal justice system, how they relate to the principle of the presumption of innocence and the tension between this and the punitive demands for increased imprisonment. In addition, this study discusses a technical solution, found in pre-trial services, which seeks to balance the presumption of innocence and the right to personal liberty with public safety.

  4. Clinical significance of endogenously labelled thyroid hormones in the diagnosis of thyroidal autonomy

    The clinical value of the determination of 123 I concentration in serum 48 hrs after tracer administration ( 123 I) 48 is investigated with special regard to thyroidal autonomy. Serum radioiodine concentration, thyroid radioiodide uptake at 4 and at 48 hrs were measured in 74 healthy subjects and patients with simple goiter, in 36 patients with thyroidal autonomy (diagnosis by thyroid suppression test), and in 20 hyperthyroid patients. 83% of the patients with elevated radioiodine concentration belonged to the group of thyroidal autonomy. The product of radioiodine concentration and thyroid radioiodide uptake is a much better parameter. 95% of the patients in which this product was elevated, belonged to the autonomy group (5% diagnostic error). Also in the control group the diagnostic error was 5%. The combination of ( 123 I) 48 with the result of the TRH-test is very useful in excluding thyroidal autonomy, if ( 123 I) 48 is normal and the TRH-test is positive (100% of the patients have regulated thyroid glands.) 94% of the patients having elevated ( 123 I) 48 and a negative TRH-test belonged to the group of thyroidal autonomy. A very useful combination for the diagnosis of borderline hyperthyroidism is the determination of the product of ( 123 I) 48 and the uptake together with the pulse rate or fine tremor of the fingers (or TRH-test). The results suggest that the determination of ( 123 I) 48 is a very good parameter of thyroidal autonomy beside the thyroid suppression test. It may be used alone for the diagnosis of thyroidal autonomy if the suppression test is contraindicated. In the diagnosis of borderline hyperthyroidism its determination makes the suppression test unnecessary in many instances. (orig.) [de

    2017-07-01

    Acute myocardial infarctions (AMI) continue to be common in the United States. Mechanical complications of AMI can lead to cardiogenic shock (CS) and death. The aim of this study was to review the cases of papillary muscle ruptures in the setting of myocardial infarctions at a tertiary care center, with a focus on the clinical presentation and echocardiographic diagnosis. This was a retrospective study from January 1, 2000 through December 31, 2014. In all, 22 patients with AMI and papillary muscle rupture (AMI-PMR) who had surgical intervention were identified. The average age was 70 (±11) with 16 (73%) males. Six patients presented with ST-elevation myocardial infarctions (STEMI) and all underwent emergent revascularization with primary percutaneous coronary intervention (PCI) prior to the diagnosis of AMI-PMR. The other 16 patients presented with a non-STEMI. In total, 17 (77%) of the 22 patients were diagnosed with an AMI-PMR within 7 days from their onset of symptoms. In all, 12 patients (55%) had anterolateral papillary muscle ruptures (ALPMR), and the other 10 had posteromedial papillary muscle ruptures (PMPMR). Ruptures were complete in 10 patients (45%). Patients presented with pulmonary edema early (14 days). Transthoracic echocardiography was able to demonstrate severe mitral regurgitation in 86% and a definitive or suggestive diagnosis in 93%. All 22 patients survived to operative management, and the overall in-hospital mortality rate was 9%. In conclusion, ischemic papillary muscle ruptures continue to occur, but with prompt diagnosis by echocardiography and rapid surgical management, the mortality rate continues to decline. © 2017, Wiley Periodicals, Inc.

    2016-01-01

    Full Text Available The paper deals with a rare monogenic connective tissue disease from a group of fibrillinopathies with autosomal dominant inheritance — Beals syndrome caused by a mutation in the FBN2 gene. Attention is drawn to the high phenotypic similarity of this disease and Marfan syndrome (FBN1 gene mutation, which is associated with the almost complete identity of two proteins: fibrillin 1 and fibrillin 2.The paper describes a clinical case of a child with Beals syndrome and the typical manifestations of the disease: asthenic constitution, arachnodactyly of the hands and feet, congenital contractures of the large and small joints, chest deformity, kyphoscoliosis, talpes, and crushed ears. The investigators made a differential diagnosis with other connective tissue diseases, such as Marfan syndrome, Stickler syndrome, Ehlers–Danlos syndrome, homocystenuria, and arthrogryposis. DNA diagnosis verified the Beals syndrome in the proband. Exon 28 in the FBN2 gene showed the previously undescribed missense mutation of c.3719G>A, resulting in the amino acid substitution of cysteine for tyrosine (p.Cys1240Tyr in the structure of the protein fibrillin 2. A de novo mutation occurred. There is evidence for its pathogenicity in the development of the clinical symptoms of the disease. The problems of effective medical genetic counseling in this family are discussed.

    Full Text Available Objectives. Fibromyalgia syndrome (FMS, characterized by subjective complaints without physical or biomarker abnormality, courts controversy. Recommendations in recent guidelines addressing classification and diagnosis were examined for consistencies or differences. Methods. Systematic searches from January 2008 to February 2013 of the US-American National Guideline Clearing House, the Scottish Intercollegiate Guidelines Network, Guidelines International Network, and Medline for evidence-based guidelines for the management of FMS were conducted. Results. Three evidence-based interdisciplinary guidelines, independently developed in Canada, Germany, and Israel, recommended that FMS can be clinically diagnosed by a typical cluster of symptoms following a defined evaluation including history, physical examination, and selected laboratory tests, to exclude another somatic disease. Specialist referral is only recommended when some other physical or mental illness is reasonably suspected. The diagnosis can be based on the (modified preliminary American College of Rheumatology (ACR 2010 diagnostic criteria. Discussion. Guidelines from three continents showed remarkable consistency regarding the clinical concept of FMS, acknowledging that FMS is neither a distinct rheumatic nor mental disorder, but rather a cluster of symptoms, not explained by another somatic disease. While FMS remains an integral part of rheumatology, it is not an exclusive rheumatic condition and spans a broad range of medical disciplines.

    The goal of this study was to determine the diagnostic capability of a multimodal spectral diagnosis (SD) for in vivo noninvasive disease diagnosis of melanoma and nonmelanoma skin cancers. We acquired reflectance, fluorescence, and Raman spectra from 137 lesions in 76 patients using custom-built optical fiber-based clinical systems. Biopsies of lesions were classified using standard histopathology as malignant melanoma (MM), nonmelanoma pigmented lesion (PL), basal cell carcinoma (BCC), actinic keratosis (AK), and squamous cell carcinoma (SCC). Spectral data were analyzed using principal component analysis. Using multiple diagnostically relevant principal components, we built leave-one-out logistic regression classifiers. Classification results were compared with histopathology of the lesion. Sensitivity/specificity for classifying MM versus PL (12 versus 17 lesions) was 100%;/100%;, for SCC and BCC versus AK (57 versus 14 lesions) was 95%;/71%, and for AK and SCC and BCC versus normal skin (71 versus 71 lesions) was 90%/85%. The best classification for nonmelanoma skin cancers required multiple modalities; however, the best melanoma classification occurred with Raman spectroscopy alone. The high diagnostic accuracy for classifying both melanoma and nonmelanoma skin cancer lesions demonstrates the potential for SD as a clinical diagnostic device.

    Full Text Available Objectives: To characterize the clinical presentations and diagnosis including serological tests and histopathological findings in children with celiac disease. Methods: All children (less than 18 years with confirmed celiac disease diagnosed over a 6 year period at a private tertiary care health care center in Riyadh, Saudi Arabia were studied retrospectively. Information collected included demographics, clinical presentation and diagnostic modalities with serology and small intestinal histology reported by Marsh grading. Results: A total of 59 children had confirmed celiac disease. Thirty (50.8% were male. Median age was 8 years (range 1 to 16 years. The mean duration of symptoms before diagnosis was 2.3 (±1.5 years. Classical disease was present only in 30.5%, whereas 69.5% had either non-classical presentations or belonged to high risk groups for celiac disease such as those with type-1 diabetes, autoimmune thyroiditis, Down syndrome and siblings. Failure to thrive was the most common presentation followed by short stature, abdominal pain and chronic diarrhea. Anti-tissue transglutaminase antibody was positive in 91.5%, and titers were no different between those with classical and non-classical disease. All had Marsh-graded biopsy findings consistent with celiac disease. Conclusion: Children with celiac disease usually present with non-classical features. A high index of suspicion needs to be maintained to consider this disorder in the diagnostic workup of pediatric patients. High risk group should be screened early to avoid complications associated with untreated celiac disease.

    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

    Full Text Available Abstract Background Although the studies published so far have found an affectation in the Health Related Quality of Life (HRQOL in both psychiatric and substance use dependence disorders, very few studies have applied HRQOL as an assessment measure in patients suffering both comorbid conditions, or Dual Diagnosis. 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 related to HRQOL. Methods Cross-sectional assessment of three experimental groups was made through the Short Form – 36 Item Health Survey (SF-36. The sample consisted of a group with Dual Diagnosis (DD; N = 35, one with Severe Mental Illness alone (SMI; N = 35 and another one with Substance Use Dependence alone (SUD; N = 35. The sample was composed only by males. To assess the clinical correlates of SF-36 HRQOL, lineal regression analyses were carried out. Results The DD group showed lower scores in most of the subscales, and in the mental health domain. The group with SUD showed in general a better state in the HRQOL while the group with SMI held an intermediate position with respect to the other two groups. Daily medication, suicidal attempts and daily number of coffees were significantly associated to HRQOL, especially in the DD group. Conclusions The DD group showed lower self-reported mental health quality of life. Assessment of HRQOL in dual patients allows to identify specific needs in this population, and may help to establish therapeutic goals to improve interventions.

    To analyze typical medical practice in managing patients with benign paroxysmal positional vertigo (BPPV). 33 patients (5 men and 28 women; mean age, 58 years) with BPPV who had been referred for consultation to the Medical Diagnostic Department, Clinic of Nervous Diseases, I.M. Sechenov First Moscow State Medical University, regarding for vertigo, were examined. Information about the disease before visiting the clinic, such as the duration of vertigo, its pattern, and triggers, previously established diagnoses, prescribed treatment and its efficacy, concomitant diseases, was analyzed. BPPV was not timely diagnosed in 93.9% of cases. The cause of vertigo was most commonly mistakenly assumed to be cerebrovascular disease (66.6%) and cervical spine pathology (15.1%). During a primary examination, none of the patients underwent positional tests (otoneurological examination) that formed the basis for the diagnosis of BPPV. Alternatively, 90.3% of cases underwent instrumental examination: magnetic resonance imaging of the brain, X-ray of the cervical spine, and ultrasonic duplex scanning of the brachiocephalic arteries. Ineffective diagnosis led to the choice of nonoptimal treatment tactics: instead of therapeutic repositioning maneuvers (RM), the patients received therapy with drugs, such as various vasoactive agents (84.8%), nootropic and chondroprotective drugs (12%), or muscle relaxants (9.1%). After BPPV was detected, all patients underwent curative RM, which resulted in regression of the disease. One-year follow-up of the patients showed that the therapeutic effect of RM persisted. Lack of effective and timely diagnosis of BPPV reflects physicians' poor awareness that this condition is the most common cause of vestibular vertigo. The role of vascular and cervicogenic factors in the development of vertigo is overestimated. Most patients with BPPV undergo unreasonable examinations and receive ineffective treatment. It is necessary to raise awareness of BPPV among of

    A 3-year-old, spayed female rat terrier was evaluated for acute onset of stupor, disorientation, and tetraparesis. Clinical signs progressed over 3 weeks to eventual right-sided hemiparesis and circling to the left. A Cuterebra spp. larva was discovered in the vomitus of the dog 2 weeks after the onset of clinical signs. Cerebrospinal fluid analysis showed chronic inflammation, and magnetic resonance imaging supported a diagnosis of a parasitic tract through the left cerebral hemisphere. Medical management included a tapering anti-inflammatory dose of prednisone. Clinical signs improved slowly over time. This is the first description of a presumptive antemortem diagnosis of canine cuterebrosis in the central nervous system.

    To estimate the cost-effectiveness of a two-step clinical rule using symptoms, signs and dipstick testing to guide the diagnosis and antibiotic treatment of urinary tract infection (UTI) in acutely unwell young children presenting to primary care. Decision analytic model synthesising data from a multicentre, prospective cohort study (DUTY) and the wider literature to estimate the short-term and lifetime costs and healthcare outcomes (symptomatic days, recurrent UTI, quality adjusted life years) of eight diagnostic strategies. We compared GP clinical judgement with three strategies based on a 'coefficient score' combining seven symptoms and signs independently associated with UTI and four strategies based on weighted scores according to the presence/absence of five symptoms and signs. We compared dipstick testing versus laboratory culture in children at intermediate risk of UTI. Sampling, culture and antibiotic costs were lowest in high-specificity DUTY strategies (£1.22 and £1.08) compared to clinical judgement (£1.99). These strategies also approximately halved urine sampling (4.8% versus 9.1% in clinical judgement) without reducing sensitivity (58.2% versus 56.4%). Outcomes were very similar across all diagnostic strategies. High-specificity DUTY strategies were more cost-effective than clinical judgement in the short- (iNMB = £0.78 and £0.84) and long-term (iNMB =£2.31 and £2.50). Dipstick tests had poorer cost-effectiveness than laboratory culture in children at intermediate risk of UTI (iNMB = £-1.41). Compared to GPs' clinical judgement, high specificity clinical rules from the DUTY study could substantially reduce urine sampling, achieving lower costs and equivalent patient outcomes. Dipstick testing children for UTI is not cost-effective. Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights reserved.

    To evaluate the applicability and clinical applications of Guidelines for Diagnosis and Treatment of Internal Diseases in Traditional Chinese Medicine, so as to provide the basis for the revision of the guidelines. This study was completed by the research and promotion base for traditional Chinese medicine(TCM) standard. The methods of applicability evaluation and application evaluation were used in the study. The questionnaires were filled out to evaluate applicability of the guideline, including doctor's familiarity with the guideline,the quality of the guideline, applicable conditions and clinical applications. The prospective case study analysis method was used to evaluate application of the guideline, including evaluation of clinical application compliance and application results(such as clinical effects, safety and economy). There were two parts in the guideline, which were TCM guideline and Western medicine guideline. The results of applicability evaluation showed that there were no obvious differences between TCM guideline and Western medicine guideline in doctor's familiarity with guideline(85.43%, 84.57%) and the use of the guideline(52.10%, 54.47%); the guidelines with good quality, and higher scores in the scope of application and the use of the term rationality(91.94%, 93.35%); the rationality scores of relevant contents in syndrome differentiation and treatment were more than 75%; the applicable conditions were better, and the safety score was the the highest. The comprehensive applicability evaluation showed that the proportion of the application of TCM guideline and Western medicine guideline were 77.73%, 75.46%, respectively. The results of application evaluation showed that there was high degree coincidence between the guideline with its clinical application; except for "other treatment" and "recuperation and prevention" in TCM, other items got high scores which were more than 90%; in the evaluation of application effects, safety of the guideline

    To describe the clinical features, diagnostic findings, treatment, and outcome of a dog with acute abdominal pain and hemoperitoneum secondary to a presumptive intraperitoneal (IP) snakebite. A 10-month-old castrated male mixed-breed dog was evaluated for suspected snake envenomation. The dog presented recumbent and tachycardic with signs of severe abdominal pain. Two cutaneous puncture wounds and hemoperitoneum were discovered during evaluation. Ultrasonographic examination revealed communication of the wounds with the peritoneal cavity. The dog was treated with supportive care, parenteral analgesia, packed red blood cell and fresh frozen plasma transfusions, crotalid antivenom, and placement of an IP catheter to provide local analgesia. The dog recovered fully and was discharged 5 days after initial presentation. To our knowledge, this is the first report of IP envenomation accompanied by hemorrhage treated with continuous IP analgesia in the veterinary literature. © Veterinary Emergency and Critical Care Society 2015.

    Full Text Available The article deals with clinical diagnosis and treatment of pityriasis rubra pilaris (PRP. The authors analyze the diagnostic errors, present literature review, and their own observations. The clinical study included 23 patients with pityriasis rubra pilaris: 18 women and 5 men, average age of 54 ± 7.2. The clinical diagnosis of all examined patients was subsequently confirmed by histological analysis of the skin. The primary clinical diagnosis was psoriasis in 15 (65.2% patients, 6 (26% patients received treatment for toxic exanthema, and only 2 (8.8% patients were presumptively diagnosed with pityriasis rubra pilaris. In conclusion, pityriasis rubra pilaris was initially misdiagnosed in 91.2% of patients. Considering the great number of diagnostic errors, we analyzed the main diagnostic and differential diagnostic features of PRP. The most effective of all synthetic retinoids in PRP treatment is acitretin. Although symptomatic improvement in PRP occurs within a month, substantial improvement, even clearing is possible within 4 - 6 months.

    Full Text Available Despite the potential of whole-genome sequencing (WGS to improve patient diagnosis and care, the empirical value of WGS in the cancer genetics clinic is unknown. We performed WGS on members of two cohorts of cancer genetics patients: those with BRCA1/2 mutations (n = 176 and those without (n = 82. Initial analysis of potentially pathogenic variants (PPVs, defined as nonsynonymous variants with allele frequency < 1% in ESP6500 in 163 clinically-relevant genes suggested that WGS will provide useful clinical results. This is despite the fact that a majority of PPVs were novel missense variants likely to be classified as variants of unknown significance (VUS. Furthermore, previously reported pathogenic missense variants did not always associate with their predicted diseases in our patients. This suggests that the clinical use of WGS will require large-scale efforts to consolidate WGS and patient data to improve accuracy of interpretation of rare variants. While loss-of-function (LoF variants represented only a small fraction of PPVs, WGS identified additional cancer risk LoF PPVs in patients with known BRCA1/2 mutations and led to cancer risk diagnoses in 21% of non-BRCA cancer genetics patients after expanding our analysis to 3209 ClinVar genes. These data illustrate how WGS can be used to improve our ability to discover patients' cancer genetic risks.

    To evaluate the diagnostic accuracy of 10 clinical tests that can be used in the diagnosis of greater trochanteric pain syndrome (GTPS) in women, and to compare these clinical tests to magnetic resonance imaging (MRI) findings. Twenty-eight participants with GTPS (49.5 ± 22.0 years) and 18 asymptomatic participants (mean age ± standard deviation [SD], 52.5 ± 22.8 years) were included. A blinded physiotherapist performed 10 pain provocation tests potentially diagnostic for GTPS-palpation of the greater trochanter, resisted external derotation test, modified resisted external derotation test, standard and modified Ober's tests, Patrick's or FABER test, resisted hip abduction, single-leg stance test, and the resisted hip internal rotation test. A sample of 16 symptomatic and 17 asymptomatic women undertook a hip MRI scan. Gluteal tendons were evaluated and categorized as no pathology, mild tendinosis, moderate tendinosis/partial tear, or full-thickness tear. Clinical test analyses show high specificity, high positive predictive value, low to moderate sensitivity, and negative predictive value for most clinical tests. All symptomatic and 88% of asymptomatic participants had pathological gluteal tendon changes on MRI, from mild tendinosis to full-thickness tear. The study found the Patrick's or FABER test, palpation of the greater trochanter, resisted hip abduction, and the resisted external derotation test to have the highest diagnostic test accuracy for GTPS. Tendon pathology on MRI is seen in both symptomatic and asymptomatic women.

    patients suspected of dementia frequently undergo additional diagnostic testing (e.g. brain imaging or neuropsychological assessment) after standard clinical assessment at a memory clinic. This study investigates the use of additional testing in an academic outpatient memory clinic and how it influences the initial diagnosis. the initial diagnosis after standard clinical assessment (history, laboratory tests, cognitive screening and physical and neurological examination) and the final diagnosis after additional testing of 752 memory clinic patients were collected. We specifically registered if, and what type of, additional testing was requested. additional testing was performed in 518 patients (69%), 67% of whom underwent magnetic resonance imaging, 45% had neuropsychological assessment, 14% had cerebrospinal fluid analysis and 49% had (combinations of) other tests. This led to a modification of the initial diagnosis in 17% of the patients. The frequency of change was highest in patients with an initial non-Alzheimer's disease (AD) dementia diagnosis (54%, compared with 11 and 14% in patients with AD and 'no dementia'; P testing 44% was diagnosed with AD, 9% with non-AD dementia and 47% with 'no dementia'. additional testing should especially be considered in non-AD patients. In the large group of patients with an initial AD or 'no dementia' diagnosis, additional tests have little diagnostic impact and may perhaps be used with more restraint. © The Author 2014.

    The added diagnostic value of (11)C-PiB-PET for the assessment of the accumulation of cortical beta-amyloid in memory clinic patients with uncertain diagnosis remains undetermined. All patients who underwent PiB-PET at the Copenhagen Memory Clinic between March 2008 and November 2011 were included in this uncontrolled, retrospective study. The standard diagnostic evaluation program included physical and neurological examination, cognitive and functional assessment, a cranial CT or MRI, functional imaging and cerebrospinal fluid sampling. Based on anonymized case reports, three experienced clinicians reached a consensus diagnosis and rated their confidence in the diagnosis before and after disclosure of PiB-PET ratings. PiB-PET scans were rated as either positive or negative. A total of 57 patients (17 females, 30 males; age 65.7 years, range 44.2-82.6) were included in the study. Twenty-seven had a positive PiB-PET scan. At the first diagnostic evaluation, 16 patients were given a clinical Alheimer's disease diagnosis (14 PiB positive). Of the 57 patients, 13 (23%) were diagnostically reclassified after PiB-PET ratings were disclosed. The clinicians' overall confidence in their diagnosis increased in 28 (49%) patients. PiB-PET adds to the specialist clinical evaluation and other supplemental diagnostic investigations in the diagnostic classification of patients with uncertain diagnosis in a specialized memory clinic.

    Full Text Available Gastrointestinal food allergy is caused by the development of allergic inflammation in the mucosa of the gastrointestinal tract. The mechanisms of this inflammation are immunogflobulin E (IgE-mediated (oral allergic syndrome, immediate gastrointestinal hypersensitivity, non-IgE-mediated (protein-induced enterocolitis syndrome, protein-induced enteropathy, protein-induced allergic proctocolitis and mixed IgE- and non-IgE-mediated reactions (eosinophilic esophagitis, eosinophilic gastritis and eosinophilic gastroenteritis. Gastrointestinal manifestations of food allergy are also combined with symptoms of atopic diseases, more often with atopic dermatitis, urticaria and angioedema. Clinical manifestations of allergic lesions of the gastrointestinal tract are different and non-specific. Common signs of gastrointestinal allergy include: vomiting (occurs from a few minutes to 4–6 hours after eating; сolic (immediately or several hours after eating; constipation; diarrhea; refusal of food (from a specific product or complete refusal to eat; abdominal pain; flatulence, the presence of mucus and eosinophils in the stool; poor appetite; headache. Differential diagnosis of gastrointestinal food allergy should be carried out with diseases such as disease and abnormalities in the development of the digestive system, mental and metabolic disorders, intoxications, infectious diseases, pancreatic endocrine gland failure, celiac disease, cystic fibrosis, immunodeficiencies, disaccharidic insufficiency, side effects of medications, endocrine pathology, irritable bowel syndrome. Methods for diagnosing gastrointestinal allergy, which currently exist, are limited and imperfect. This requires further scientific researches aimed at timely detection of this pathology, prevention in genetically predisposed children, development of optimal diagnostic algorithms, prevention of the progression of clinical manifestations, the choice of individual diet therapy and

    The objective of this study was to report the clinical course of a cohort of patients with clinically amyopathic dermatomyositis (CADM) in correlation to the presence or absence of anti-melanoma differentiation-associated gene 5 (MDA-5) antibody. Five patients with CADM presented to our rheumatology unit between September 1, 2011 and March 31, 2014. We hereby present their clinical course, laboratory findings, imaging modalities, functional tests, and treatments regimens. Our cohort included five patients, with a mean age of 41.8 ± 17.7. Three patients, all anti-MDA-5 antibody positive, developed rapidly progressive interstitial lung disease (ILD) within 4.3 ± 4.5 months of presentation. Two of these patients succumbed to their disease within 30 months of diagnosis despite intensive immunosuppressive therapy. The third anti-MDA-5-positive patient with ILD is still stable, 20 months from disease onset, on massive combination therapy. One patient developed CADM associated with the anti-p155/140 antibody, a year after completing chemotherapy for non-seminomatous germ cell tumor. He presented with a benign clinical course with no evidence of ILD and no recurrence of malignancy after 20 months of follow-up. The fifth patient in our cohort, who is anti-MDA-5 negative and has no evidence of malignancy, also enjoys a benign clinical course. The presence of anti-MDA-5 antibodies in CADM patients is associated with rapidly progressive ILD and a poor prognosis. The serologic profile of patients with CADM should be routinely evaluated and integrated with clinical data in the management of these patients.

    Setting: Sputum smear microscopy, the primary diagnostic tool used for diagnosis of tuberculosis (TB) in India's Revised National TB Control Programme (RNTCP), has low sensitivity, resulting in a significant number of TB cases reported as sputum-negative. As the revised guidelines pose challenges in implementation, sputum-negative presumptive TB (SNPT) patients are subjected to 2 weeks of antibiotics, followed by chest X-ray (CXR), resulting in significant loss to care among these cases. Objective: To determine whether reducing delays in CXR would yield additional TB cases and reduce initial loss to follow-up for diagnosis among SNPT cases. Methods: In an ongoing intervention in five districts of Maharashtra, SNPT patients were offered upfront CXR. Results: Of 119 male and 116 female SNPT patients with a mean age of 45 years who were tested by CXR, 32 (14%) were reported with CXR suggestive of TB. Administering upfront CXR in SNPT patients yielded twice as many additional cases, doubling the proportion of cases detected among all those tested as against administering CXR 2 weeks after smear examination. Conclusion: Our interventional study showed that the yield of TB cases was significantly greater when upfront CXR examination was undertaken without waiting for a 2-week antibiotic trial.

    Full Text Available The incidence of tuberculosis (TB is high in patients undergoing chronic dialysis than it is in the general population. The diagnosis of TB is often difficult and extrapulmonary involvement is predominant. This study investigates the spectrum of clinical presentations and outcome in dialysis patients during a nine-year period. TB was diagnosed in 41 patients. Anti-TB drugs, adverse effects of therapy, and outcome were noted. Thirty-eight patients (92.6% were on hemodialysis and three were on peritoneal dialysis (7.3%. The mean age at diagnosis was 50.8 years and the male/female ratio was 1.16. Four patients had a history of pulmonary TB. Extrapulmonary involvement was observed in 32 (78 % patients. The bacteriological confirmation was made in 41.46% and histological confirmation was made in 26.83%, and in the rest, the diagnosis was retained on the criterion presumption. Nineteen patients (46.34% developed adverse effects of antitubercular drugs. Eight patients (19.51% died during the study from TB or adverse effects of treatment. Low urea reduction ratio and female sex were associated with poor prognosis in our study. The clinical manifestations of TB in patients on dialysis are quite nonspecific, making timely diagnosis difficult, and delaying the initiation of curative treatment, which is a major determinant of the outcome.

    To explore the diagnostic accuracy of acute appendicitis among different patient groups and evaluate the statistical diagnostic values of common pathology and imaging tests for the diagnosis of acute appendicitis. Proportions of histology-proven appendicitis in different patient groups. Statistical parameters including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (+LR), negative likelihood ratio (-LR) and diagnostic odds ratio (DOR) between the histology-proven appendicitis and abnormal results of U/S, CT, WCC, CRP, bilirubin, pancreatic, and combined test results of WCC and CRP. Our data showed that up to 25.7% of patients underwent appendectomy has normal appendix. Appendicitis is often accurately diagnosed among male patients, up to 90.3% of the time, while misdiagnosis of appendicitis among young females (appendicitis, sensitivity > 90%, and no individual pathology test out of those examined can rival the sensitivity of CT. Nevertheless, by examining the combined results of WCC and CRP, we found that abnormal results in one or both these yields sensitivity similar to CT scans in detecting acute appendicitis, up to 95%. Young female patients have highest risk of being falsely diagnosed with acute appendicitis and hence unnecessary surgery. Bilirubin and lipase exhibit no correlations with acute appendicitis. Combined interpretation of WCC or CRP abnormal results yields competitive sensitivity as CT. Hencewe would suggest that, under the appropriate clinical context, one can use both WCC and CRP as a simple tool to support the diagnosis of appendicitis. If both tests show normal results, we would highly recommend considering alternative diagnosis. Published by the BMJ Publishing Group Limited.

    Hofmann, Sabine

    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

  14. Cerebrotendinous xanthomatosis: a comprehensive review of pathogenesis, clinical manifestations, diagnosis, and management.

    2014-11-26

    Cerebrotendinous xanthomatosis (CTX) OMIM#213700 is a rare autosomal-recessive lipid storage disease caused by mutations in the CYP27A1 gene; this gene codes for the mitochondrial enzyme sterol 27-hydroxylase, which is involved in bile acid synthesis. The CYP27A1 gene is located on chromosome 2q33-qter and contains nine exons. A CYP27A1 mutation leads to decreased synthesis of bile acid, excess production of cholestanol, and consequent accumulation of cholestanol in tissues. Currently there is no consensus on the prevalence of CTX, one estimate being CYP27A1 mutation R362C alone is approximately 1/50,000 in Caucasians. Patients with CTX have an average age of 35 years at the time of diagnosis and a diagnostic delay of 16 years. Clinical signs and symptoms include adult-onset progressive neurological dysfunction (i.e., ataxia, dystonia, dementia, epilepsy, psychiatric disorders,peripheral neuropathy, and myopathy) and premature non-neurologic manifestations (i.e., tendon xanthomas, childhood-onset cataracts, infantile-onset diarrhea, premature atherosclerosis, osteoporosis, and respiratory insufficiency). Juvenile cataracts, progressive neurologic dysfunction, and mild pulmonary insufficiency are unique symptoms that distinguish CTX from other lipid storage disorders including familial dysbetalipoproteinemia, homozygous familial hypercholesterolemia, and sitosterolemia, all of which might also present with xanthomas and cardiovascular diseases. Brain magnetic resonance imaging (MRI) shows bilateral lesions in the dentate nucleus of the cerebellum and mild white matter lesions. The classical symptoms and signs, namely elevated levels of cholestanol and bile alcohols in serum and urine, brain MRI, and the mutation in the CYP27A1 gene confirm the diagnosis of CTX. Early diagnosis and long-term treatment with chenodeoxycholic acid (750 mg/d) improve neurological symptoms and contribute to a better prognosis.

    Hepatitis E virus (HEV) is an emergent virus of global importance; it is the etiological agent of sporadic cases and outbreaks of hepatitis. The epidemiology of this infection in Colombia is unknown. To determine the seropositivity for hepatitis E virus in Colombia in cases with clinical diagnosis of viral hepatitis. Serum samples from patients that were sent to the Instituto Nacional de Salud during the period 2005-2010 (group 1) and samples sent to the Laboratorio Departamental de Salud Pública de Antioquia during the 2008-2009 period were included in this study (group 2). Serum samples were analyzed by immunoassay with commercial kits. From the 344 analyzed samples, 8.7% were positive for anti-HEV; the frequency of anti-HEV IgM was 1.74% (6/344) and the frequency of anti-HEV IgG was 7.5% (26/344). A difference in frequency of anti-HEV between group 1 (6.3%) and group 2 (1.3%) was observed. The cases were identified in nine departments of Colombia. This is the first study of hepatitis E virus infection in patients with diagnosis of hepatitis in Colombia. The frequency of anti-HEV described in this population of patients in Colombia is similar to that described in other Latin American countries like Brazil, Perú and Uruguay. Considering the results of this study, it could be necessary to include hepatitis E virus infection serological markers in the differential diagnosis of viral hepatitis in Colombia.

    In 1979 histologically confirmed cases of carcinoma of the breast the diagnostic values of clinical examination, mammography and aspiration biopsy were compared. The effect of combining these three diagnostic methods was evaluated. Clinical examination and mammography each produced a positive diagnosis in 89% of the cases, and in 88% aspiration biopsy. A combination of these three methods enabled a positive diagnosis of carcinoma of the breast in 99% of the cases. Fine needle biopsy and mammography carried out by the clinician seem to be as effective as when done by the cytologist and diagnostic radiologist. A combination of clinical examination, mammography and aspiration biopsy increases the diagnostic accuracy of breast cancer. (orig.) [de

    Chronic-thromboembolic pulmonary hypertension (CTEPH) is a serious complication of acute pulmonary embolism (PE). In untreated patients prognosis is poor. It depends on WHO-functional class. A delay from onset of symptoms and diagnosis can lead to a further worsening of prognosis. A pulmonary endarterectomy is the treatment of choice. We aimed to evaluate the time delay from onset of symptoms to diagnosis and the WHO-functional class at primary diagnosis in patients with CTEPH. Retrospective analysis of data from 70 monocentrically registered patients (48 women, 22 men, mean age 66,2 years  ±  13,8 years) with confirmed CTEPH from the pulmonary hypertension expert center Missionsärztliche Klinik. Diagnostic work-up was performed according to the current guidelines. Mean delay from onset of symptoms to diagnosis of CTEPH was 18 ± 26 months. Time delay was only slightly shorter in patients with a history of PE (n = 56; 81 %) than in patients without a history of PE (n = 13; 19 %): 16,9  ±  23,8 vs. 23,5  ±  36,9 months. Time delay was higher in patients who received vasoactive medication before the first contact with a PH expert center and in patients who were classified as technically not suitable for a thrombendarterectomy. 38 patients with a history of acute PE did not have a period without symptoms. In 18 patients symptoms had transiently gone after PE. More than 70 % presented in WHO functional class III or IV. Time delay between onset of symptoms and diagnosis of CTEPH and referral to a PH expert center is long and the majority of patients presented in WHO-functional class III or IV. Prognosis is poor in untreated patients and getting worse with a higher WHO-functional class. For this reason, and because CTEPH can be cured by a pulmonary endarterectomy, each patient with suspected PH should be referred to a PH expert center to exclude CTEPH. © Georg Thieme Verlag KG Stuttgart · New York.

    Cerebral palsy is the most common physical disability in childhood, and is mostly diagnosed after age 2 years. Delays in diagnosis can have negative long-term consequences for children and parents. New guidelines for early cerebral palsy diagnosis and intervention were recently published, after systematic review of the evidence by international multidisciplinary experts aiming to decrease age at diagnosis. The current study tested the feasibility of implementing these guidelines in an American clinical setting. We designed a stepwise implementation process in a neonatal intensive care follow-up clinic. Efficacy was tested by comparing 10-month pre- and post-implementation periods. Clinic visit types, cerebral palsy diagnosis, provider competencies and perspectives, and balancing measures were analyzed. Changes to infrastructure, assessments, scheduling algorithms, documentation and supports in diagnosis or counseling were successfully implemented. Number of three- to four-month screening visits increased (255 to 499, P cerebral palsy care guidelines for infants under age 2 years. We demonstrated for the first time in a US clinical setting the feasibility of implementation of international early diagnosis and treatment guidelines for cerebral palsy. This process is adaptable to other settings and underscores the necessity of future research on cerebral palsy treatments in infancy. Copyright © 2017 The Authors. Published by Elsevier Inc.

    The CT discographic findings of 56 discs in 43 patients with low-back and/or leg pain were evaluated mainly from the clinical standpoint including pain provocation during the injection of the contrast material, correlation between the type of the herniation and symptoms and clinical course after the examination. The clinical value of CT discography is controversial, but it is well recognized that CT discography is the diagnostic method of choice for equivocal situations as patients showing negative myelography and significant symptoms and for the preoperative evaluation of patient thought to have the extreme lateral disc herniation. Exact provoked pain response was noted in 72 % of 43 pathologic discs and almost all discs especially in patients showing positive SLR test at less than 70 deg. So this pain response seems to provide additional information indicating the true pathologic disc level. Sciatic pain in the legs was much more frequently seen in the paramedian or lateral type herniation, but there was no relation between low-back pain and central type herniation. Majority of either type of disc herniation showed both low-back and leg pains. This suggests that clinical symptoms are based on not only disc herniation but also disc degeneration itself. We injected steroid (4 mg of Decadron) and local anesthetic (1 ml of 1 % Carbocain) into the disc after the examination for the purpose of improving the clinical symptoms as the first attempt. Definite improvement of various degree was noted in 56 % of total 43 cases after the procedure and CT discography was thought to be a valuable method of diagnosis in proper indications despite risky needle puncture.

    Emmanuel, Babatunde S

    2012-08-01

    This paper presents an overview of approaches to analysis of heart sound signals. The paper reviews the milestones in the development of phonocardiogram (PCG) signal analysis. It describes the various stages involved in the analysis of heart sounds and discrete wavelet transform as a preferred method for bio-signal processing. In addition, the gaps that still exist between contemporary methods of signal analysis of heart sounds and their applications for clinical diagnosis is reviewed. A lot of progress has been made but crucial gaps still exist. The findings of this review paper are as follows: there is a lack of consensus in research outputs; inter-patient adaptability of signal processing algorithm is still problematic; the process of clinical validation of analysis techniques was not sufficiently rigorous in most of the reviewed literature; and as such data integrity and measurement are still in doubt, which most of the time led to inaccurate interpretation of results. In addition, the existing diagnostic systems are too complex and expensive. The paper concluded that the ability to correctly acquire, analyse and interpret heart sound signals for improved clinical diagnostic processes has become a priority.

    To evaluate patients' profiles, demographics, clinical and therapeutic approaches and strategies in patients with tuberculous lymphadenitis (TBG). A retrospective study of all TBG-confirmed cases admitted in a tuberculosis-specific health care facility between 1 January 2009 and 16 June 2013. A total of 181 clinical files were examined. Mean age was 32years old; the female/male ratio was 1.78 to 1. Raw milk consumption was noted in 1/3 of patients. Most cases involved the head and neck region (83.4%), nodes involvement, including axillary (12 cases), and mediastinal (9 cases). Clinical symptoms were present in only 55.2%. Tuberculin skin test (TST) was conducted with 82.6% positive responses. Diagnostics confirmation was done with anatomical pathology in most of the patients; only 56 of them had any microbiology analysis done. Demonstration of acid-fast bacilli in microscopy from either fine-needle aspirates or biopsies was done in 17.5% of cases, and cultures yielded positive results in 27%. Treatment duration was varied. Paradoxical reactions were noted in 12% and persistent lymphadenopathy after treatment completion was noted in 10% of cases. TBG remains a disease of interest. Today, its diagnosis and management is still a problem despite its increasing worldwide incidence, and especially in this study area. Disease control should be strengthened in this country.

    Haemoglobinopathies constitute entities that are generated by either an abnormal haemoglobin or thalassaemias. While abnormal haemoglobins are caused by a qualitative structural abnormality of the haemoglobin molecule, thalassaemias result by diminished synthesis of the globin chain. Due to increased immigration from Asia, Africa and the Mediterranean to Northern Europe, haemoglobin S, haemoglobin C, haemoglobin E are also encountered commonly in Switzerland, while other abnormal haemoglobins are rare, yet can cause clinically relevant symptoms. This include haemolysis, polyglobulia, cyanosis or a combination thereof Thalassaemia-syndroms constitute with two million affected individuals to the most prelevant monogenetic diseases worldwide. Due to migration into Switzerland, they are also found quite commonly among our patients with 10-15 per cent of all hypochromic, microcytic, anemia second only to iron deficiency. Importantly, thalassaemias and haemoglobinopathies can occur concomitantly sometimes even with a normal haemoglobin variant. This results in wide-spread presentations, making diagnosis and clinical judgement difficult. We describe in this article not only physiological mechanisms and clinical presentation but also propose a step-wise diagnostic algorithm including selective use of molecular biology methods.

    To assess the relation between location and intensity of pain in the articular interline as reported by the patient and proven objectively with the physical exam, and the type and location of the meniscal lesion found in the knee imaging study and arthroscopy. Prospective, observational, longitudinal study including 34 consecutive patients with a clinical and arthroscopic diagnosis of symptomatic meniscal tears. Pain location was reported, an MRI was taken and finally all patients were assessed with knee arthroscopy. We found an excellent correlation between the clinical manifestation of pain and the arthroscopic findings (p meniscal pathology with the anatomical lesion could be useful at the time of deciding to perform surgery, as the clinical identification of certain types of meniscal tears could potentially determine what the best time to perform surgery is. Our study shows that there is no significant relation neither between the magnitude of pain and the laterality of the lesion, nor between the magnitude of pain and the type of lesion diagnosed arthroscopically. This shows that patients cannot be selected considering the anatomy of the lesion based only on the physical exam.

    In Graves' ophthalmopathy (GO) it is important to distinguish acute inflammation at an early stage, responsive to immunosuppressive treatment, from inactive fibrotic end stage disease, unresponsive to the same treatment. The purpose of this study was to identify the most relevant signal intensities on orbital MR imaging with contrast administration both to classify patients according to their clinical activity score (defined by a cut-off value of 3) and to make a prediction of patient's CAS. Such threshold was considered as widely used in literature. Sixteen consecutive patients with a diagnosis of GO in different phases of thyroid disease based on clinical and orbital MR imaging signs, and six normal volunteers were examined. Orbital MR imaging was performed on a 1.5 Tesla MR Unit. MR scans were assessed by an experienced neuroradiologist, blinded to the clinical examinations. We found a statistical correlation between CAS and both STIR and contrast enhanced T1-weighted sequences. There was also a statistically significant correlation between STIR and contrast-enhanced T1 images disclosing the possibility of avoiding the injection of contrast medium. Our study proved that signal intensity values on STIR sequence increase in the inflammatory oedematous phase of disease. We confirmed the correlation between signal intensities on this sequence and CAS, showing an increase in signal intensity proportional to the CAS value. So we validated MRI use to establish the activity phase of disease more sensitively than CAS alone.

    Absence of the CSP on prenatal imaging is historically associated with additional anomalies, however recently cases of isolated, absent CSP have also been identified. This study seeks to assess the accuracy of prenatal imaging in evaluating isolated, absent CSP and to describe the spectrum of clinical outcomes. This is a retrospective observational study of all prenatally diagnosed absent CSP cases between 2011 and 2016 at our institution. Cases with additional structural parenchymal abnormalities were excluded. Clinical outcomes were abstracted from available records. We identified 15 cases of prenatally diagnosed isolated absent CSP. All patients were initially diagnosed on ultrasound and 11/15 patients had fetal MRI confirming the diagnosis. Prenatal US and MRI were concordant in all cases. Of the continuing pregnancies, two neonatal deaths occurred related to extreme prematurity. Two cases of SOD were identified in our cohort. In this study, fetal MRI and US had a high degree of accuracy with concordant postnatal imaging. Our study is similar to other case series suggesting that a range of clinical outcomes is possible with isolated absent CSP, but long term patient follow up is necessary.

    Science.gov (United States)

    2018-01-23

    Hereditary colorectal cancer can be divded into two categories based on the presence or absence of polyps. The first category is characterized by the development of polyposis, which includes familial adenomatous polyposis (FAP); The second category is nonpolyposis colorectal cancer, which is represented by Lynch syndrome. "Consensus on clinical diagnosis, treatment and pedigree management of hereditary colorectal cancer in China" developed by the Genetics Group of the Committee of Colorectal Cancer, Chinese Anti-cancer Association, is composed of three sections, including hereditary nonpolyposis syndrome, polyposis syndrome as well as genetic evaluation of hereditary colorectal cancer. The consensus aims to provide recommendations on management of the respective hereditary syndromes in terms of definition, clinical and pathological features, diagnostic standards, treatment, and follow-ups. In addition to describing diagnostic and treatment strategies, prophylactic treatment as well as genetic screening and pedigree monitoring is highly recommended. Through the establishment of this expert consensus, we hope to promote better understanding of hereditary colorectal cancer for clinicians and encourage standardized treatment through multidisciplinery approaches, eventually improving clinical treatment and pedigree management of hereditary colorectal cancer in China.

    Whole-exome sequencing is a diagnostic approach for the identification of molecular defects in patients with suspected genetic disorders. We developed technical, bioinformatic, interpretive, and validation pipelines for whole-exome sequencing in a certified clinical laboratory to identify sequence variants underlying disease phenotypes in patients. We present data on the first 250 probands for whom referring physicians ordered whole-exome sequencing. Patients presented with a range of phenotypes suggesting potential genetic causes. Approximately 80% were children with neurologic phenotypes. Insurance coverage was similar to that for established genetic tests. We identified 86 mutated alleles that were highly likely to be causative in 62 of the 250 patients, achieving a 25% molecular diagnostic rate (95% confidence interval, 20 to 31). Among the 62 patients, 33 had autosomal dominant disease, 16 had autosomal recessive disease, and 9 had X-linked disease. A total of 4 probands received two nonoverlapping molecular diagnoses, which potentially challenged the clinical diagnosis that had been made on the basis of history and physical examination. A total of 83% of the autosomal dominant mutant alleles and 40% of the X-linked mutant alleles occurred de novo. Recurrent clinical phenotypes occurred in patients with mutations that were highly likely to be causative in the same genes and in different genes responsible for genetically heterogeneous disorders. Whole-exome sequencing identified the underlying genetic defect in 25% of consecutive patients referred for evaluation of a possible genetic condition.

    2016-01-01

    Synopsis Nanotechnology is an emerging field of medicine with significant potential to become a powerful adjunct to cancer therapy, and in particular, thoracic surgery. Using the unique properties of several different nanometer-sized platforms, therapy can be delivered to tumors in a more targeted fashion, with less of the systemic toxicity associated with traditional chemotherapeutics. In addition to the packaged delivery of chemotherapeutic drugs, nanoparticles show potential to aid in the diagnosis, pre-operative characterization, and intraoperative localization of thoracic tumors and their lymphatics. With increasing interest in their clinical application, there is a rapid expansion of in vitro and in vivo studies being conducted that provide a better understanding of potential toxicities and hopes of broader clinical translation. Focused research into nanotechnology’s ability to deliver both diagnostics and therapeutics has led to the development of a field known as nanotheranostics which promises to improve the treatment of thoracic malignancies through enhanced tumor targeting, controlled drug delivery, and therapeutic monitoring. This article reviews the various types of nanoplatforms, their unique properties, and the potential for clinical application in thoracic surgery. PMID:27112260

    2016-07-01

    Full Text Available The actuality of this article is determined by the necessity of implementing fiscal simplicity for increasing tax compliance through fiscal education of small business representatives. In many developing and transition countries, micro and small enterprises are the most rapidly growing business segment. Tax compliance attitude within this sector varies significantly because high conformation costs and difficult formalization procedures can determine many small enterprises to operate in the informal economy. Thus tax regulation of small enterprises is crucial in the process of small entrepreneurs fiscal education and tax simplification of SMEs in many countries becomes one of the most efficient instruments. The main research methods were systemic analysis and logic synthesis. The main results obtained in article, as a result of research, are identification, analysis and systematization of foreign countries’ practices in implementing presumptive tax design and elaboration of some recommendations on fiscal simplicity.

    Purpose: To work out the routine and three dimensional reconstruction (3D) methods of electron beam computed tomography angiography (EBCTA) and evaluate its clinical application. Materials and methods: In this group, 189 cases with aortic diseases (152 male, 37 female) were studied retrospectively. The EBCT scan methods were enhanced single slice mode (SSM) and continuous volume scan (CVS); The 3D reconstruction methods were shaded surface display (SSD), maximum intensity projection (MIP) and multiple/curved planar reconstruction (MPR/CPR). Results: In 189 cases, including 97 cases with aortic dissection, 26 cases with aortic aneurysm and 8 cases with pseudo aneurysm, others including Marfan's syndrome in 37 cases, Takayasu's arteritis in 5 cases and congenital aortic malformations in 14 cases; 68 cases received operation and the EBCT diagnosis coincided well with the operative findings in 97% of cases. Conclusion: EBCT angiographic images have very high temporal resolution and most artifacts are eliminated. The 3D images are in helpful accurate diagnosis and direct surgical operation. In the management of aortic diseases, EBCT angiography and 3D reconstruction may supplant conventional angiography in the near future

    2013-01-01

    Lamellar ichthyosis (LI) is a rare inherited skin disorder of cornification, with an incidence of approximately 1 in 200,000 births. It is one of three types of autosomal recessive congenital ichthyosis (ARCI), a collective term for the spectrum of nonsyndromic ichthyoses caused by a number of well-described genetic mutations. We describe the case of LI diagnosed in a 10-day-old child of a Somali refugee at a free clinic in downtown Djibouti. Initial concern was for staphylococcal infection versus congenital disease. With the use of digital photographs, consultation with experts accessed through the Army Teledermatology Consultation Service supported a diagnosis of ARCI. Providing care to patients in austere environments can present numerous medical challenges. A provider cannot be expected to be able to diagnose and treat every disease and disorder alone, especially if there is a language barrier. Telemedicine can help close the gap in knowledge, particularly when presented with a challenging case. With a novel presentation, simply taking a photograph and e-mailing a consultant can quickly augment one?s medical acumen, ensuring appropriate diagnosis and treatment. 2013.

    Twenty-nine kidneys of seventeen patients (nine boys and eight girls) with vesicoureteral reflux and repeated urinary tract infection were studied by magnetic resonance imaging for diagnosis of renal scarring and correlation between clinical data and the degree renal scarring. Renal scarring is classified into three types according to findings in magnetic resonance imaging. The degree of renal scarring are classified into five grades according to traditional grading of intravenous pyelogram. If a fine deformity of calyx is shown on intravenous pyelogram, magnetic resonance imaging demonstrates renal scarring. Magnetic resonance imaging without irradiation is exceedingly valuable for the diagnosis of renal scarring. The appearances of magnetic resonance imaging were supported by X-ray computed tomography. There is a substantial correlation between serum creatinine and the grades of renal scarring by magnetic resonance imaging. There is a substantial correlation between fever attacks and the grade of renal scarring, and there is a significant reverse correlation between the age of the onset of upper urinary tract infection and the grade of renal scarring. It is suggested that upper urinary tract infection is the most significant factor in scar formation. (author).

    Classical galactosemia (CG) is an inborn error of galactose metabolism. Evidence-based guidelines for the treatment and follow-up of CG are currently lacking, and treatment and follow-up have been demonstrated to vary worldwide. To provide patients around the world the same state-of-the-art in care, members of The Galactosemia Network (GalNet) developed an evidence-based and internationally applicable guideline for the diagnosis, treatment, and follow-up of CG. The guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. A systematic review of the literature was performed, after key questions were formulated during an initial GalNet meeting. The first author and one of the working group experts conducted data-extraction. All experts were involved in data-extraction. Quality of the body of evidence was evaluated and recommendations were formulated. Whenever possible recommendations were evidence-based, if not they were based on expert opinion. Consensus was reached by multiple conference calls, consensus rounds via e-mail and a final consensus meeting. Recommendations addressing diagnosis, dietary treatment, biochemical monitoring, and follow-up of clinical complications were formulated. For all recommendations but one, full consensus was reached. A 93 % consensus was reached on the recommendation addressing age at start of bone density screening. During the development of this guideline, gaps of knowledge were identified in most fields of interest, foremost in the fields of treatment and follow-up.

    Quantitative susceptibility mapping (QSM) is an MR technique that depicts and quantifies magnetic susceptibility sources. Mapping iron, the dominant susceptibility source in the brain, has many important clinical applications. Herein, we review QSM applications in the diagnosis, medical management, and surgical treatment of disease. To assist in early disease diagnosis, QSM can identify elevated iron levels in the motor cortex of amyotrophic lateral sclerosis patients, in the substantia nigra of Parkinson's disease (PD) patients, in the globus pallidus, putamen, and caudate of Huntington's disease patients, and in the basal ganglia of Wilson's disease patients. Additionally, QSM can distinguish between hemorrhage and calcification, which could prove useful in tumor subclassification, and can measure microbleeds in traumatic brain injury patients. In guiding medical management, QSM can be used to monitor iron chelation therapy in PD patients, to monitor smoldering inflammation of multiple sclerosis (MS) lesions after the blood-brain barrier (BBB) seals, to monitor active inflammation of MS lesions before the BBB seals without using gadolinium, and to monitor hematoma volume in intracerebral hemorrhage. QSM can also guide neurosurgical treatment. Neurosurgeons require accurate depiction of the subthalamic nucleus, a tiny deep gray matter nucleus, prior to inserting deep brain stimulation electrodes into the brains of PD patients. QSM is arguably the best imaging tool for depiction of the subthalamic nucleus. Finally, we discuss future directions, including bone QSM, cardiac QSM, and using QSM to map cerebral metabolic rate of oxygen. Copyright © 2016 John Wiley & Sons, Ltd.

    To study clinical significance of vertebral artery magnetic resonance angiography (MRA) to vertebral artery type of cervical spondylosis' diagnosis and treatment. There were two groups in the study, which were observation group and control group. There were 53 patients in observation group,including 19 males and 34 females,with a mean age of (52.51 +/- 11.29) years. There were 30 subjects in control group,including 10 males and 20 females,with a mean age of (48.11 +/- 12.21) years. Based on the vertebral artery MRA picture,the course and caliber of vertebral artery were compared between two groups. The abnormal incidence of course and caliber of vertebral artery in observation group was higher than that of control group, which had statistic difference (P=0.000). Furthermore, the patterns of abnormal course and caliber of vertebral artery in observation group were complicated and diverse, but the regional circuity and stegnosis was the most common pattern,about 47.18%(25/53). The cause of circuity and stegnosis was vertebra Gu-Cuofeng,about 43.41% (23/53). The vertebral artery MRA provides a guidance for the diagnosis of abnormal course and caliber of vertebral artery in vertebral artery cervical spondylosis.

    Cannabinoids may hold potential for the management of rheumatic pain. Arthritis, often self-reported, is commonly cited as the reason for the use of medicinal herbal cannabis (marijuana). We have examined the prevalence of marijuana use among 1000 consecutive rheumatology patients with a rheumatologist-confirmed diagnosis and compared in an exploratory manner the clinical characteristics of medicinal users and nonusers. Current marijuana use, medicinal or recreational, was reported by 38 patients (3.8%; 95% CI: 2.8-5.2). Ever use of marijuana for medical purposes was reported by 4.3% (95% CI: 3.2-5.7), with 28 (2.8%; 95% CI: 1.9-4.0) reporting current medicinal use. Current medicinal users had a spectrum of rheumatic conditions, with over half diagnosed with osteoarthritis. Medicinal users were younger, more likely unemployed or disabled, and reported poorer global health. Pain report and opioid use was greater for users, but they had similar physician global assessment of disease status compared with nonusers. Medicinal users were more likely previous recreational users, with approximately 40% reporting concurrent recreational use. Therefore, less than 3% of rheumatology patients reported current use of medicinal marijuana. This low rate of use in patients with a rheumatologist-confirmed diagnosis is in stark contrast to the high rates of severe arthritis frequently reported by medicinal marijuana users, especially in Canada. Familiarity with marijuana as a recreational product may explain use for some as disease status was similar for both groups.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the clinical significance of reticulocyte hemoglobin content (CHr in the diagnosis of iron deficiency anemia (IDA and to compare it with other conventional iron parameters. METHODS: A total of 32 female patients with IDA (serum hemoglobin 120 g/L and serum ferritin <20 ng/mL were enrolled. RESULTS: CHr was 24.95±3.92 pg in female patients with IDA and 29.93±2.96 pg in female patients with iron deficiency. CHr showed a significant positive correlation with hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, serum iron, and transferrin saturation and a significant negative correlation with transferrin and total iron-binding capacity. The cut-off value of CHr for detecting IDA was 29 pg. CONCLUSION: Our data demonstrate that CHr is a useful parameter that can be confidently used in the diagnosis of IDA, and a CHr cut-off value of 29 pg predicts IDA.

    The value of computed tomography (CT) in the preoperative clinical staging of rectal cancer was prospectively studied in 28 patients with macroscopically proven cancer. The CT studies were based on the previously established CT diagnostic criteria for wall invasion (S factor), lymph node metastases (N factor), and liver metastases (H factor). When macroscopic findings were used as the standard, the accuracy of CT was 61 % for S factor, 32 % for N factor, and 86 % for H factor. Using histological findings as the standard, the accuracy was 48 % for S factor and 16 % for N factor. Overall, CT had a high accuracy for H factor in all sites of cancer (75 % in the rectosigmoid, 86 % in the area above the peritoneal reflection, and 90 % in the area below the peritoneal reflection). For the other S and N factors, CT seemed to be of limited value in the preoperative diagnosis. (Namekawa, K.)

    Full Text Available The traditional Chinese medicine (TCM constitution theory is an important means to reveal the host′s genetic characteristics from the perspective of TCM. The types of constitution can influence liver pathological changes and the prognosis of disease in patients with chronic hepatitis B virus infection, and to a certain degree, they are associated with the polymorphisms of genes involved in immunoregulation, for example, human leukocyte antigen(HLA class Ⅱ gene. Yin-deficiency constitution is associated with various adverse clinical outcomes, as well as the genotypes of genes including HLA-DQA1*0501. Preliminary data also show that the chronic hepatitis B (CHB patients with yin-deficiency constitution have a poor response to interferon therapy. This article reviews the current application of TCM constitution theory in the diagnosis and treatment of CHB, its potential value, and existing problems.

    Approximately half of all patients presenting to dermatologists exhibit signs and symptoms of psychiatric conditions that are either primary or secondary to cutaneous disease. Because patients typically resist psychiatric consult, dermatologists often are on the front line in evaluating and treating these patients. Accordingly, distinguishing the specific underlying or resulting psychiatric condition is essential for effective treatment. The etiology, epidemiology, clinical presentation, diagnosis, and first-line treatment of specific primary psychiatric causes of dermatologic conditions, including delusional infestation, Morgellons syndrome, olfactory reference syndrome, body dysmorphic disorder, excoriation disorder, trichotillomania, and dermatitis artefacta are discussed here, followed by a discussion of the recommended treatment approach with an overview of the different first-line therapies discussed in this review, specifically cognitive behavioral therapy, atypical antipsychotics, selective serotonin reuptake inhibitors, and tricyclic antidepressants. Included is a guide for dermatologists to use while prescribing these medications.

    Mantle cell lymphoma (MCL) is a non-Hodgkin lymphoma characterized by involvement of the lymph nodes, spleen, blood, and bone marrow with a short remission duration to standard therapies and a median overall survival of 4-5 years. Diagnosis is based on lymph node, bone marrow, or tissue morphology of centrocytic lymphocytes, small cell type, or blastoid variant cells. A chromosomal translocation t(11:14) is the molecular hallmark of MCL, resulting in the overexpression of cyclin D1. Cyclin D1 is detected by immunohistochemistry in 98% of cases. The absence of SOX-11 or a low Ki-67 may correlate with a more indolent form of MCL. The differential diagnosis of MCL includes small lymphocytic lymphoma, marginal zone lymphoma, and follicular lymphoma. The mantle cell lymphoma international prognostic index (MIPI) is the prognostic model most often used and incorporates ECOG performance status, age, leukocyte count, and lactic dehydrogenase. A modification of the MIPI also adds the Ki-67 proliferative index if available. The median overall survival (OS) for the low-risk group was not reached (5-year OS of 60%). The median OS for the intermediate risk group was 51 and 29 months for the high-risk group. For selected indolent, low MIPI MCL patients, initial observation may be appropriate therapy. For younger patients with intermediate or high risk MIPI MCL, aggressive therapy with a cytarabine containing regimen ± autologous stem cell transplantation should be considered. For older MCL patients with intermediate or high risk MIPI, combination chemotherapy with R-CHOP, R-Bendamustine, or a clinical trial should be considered. At the time of relapse, agents directed at activated pathways in MCL cells such as bortezomib (NFkB inhibitor), BTK inhibitors or CAL-101 (B-cell receptor inhibitors) or lenalidamide (antiangiogenesis) have clinical activity in MCL patients. Autologous or allogeneic stem cell transplantation can also be considered in young patients. Copyright © 2012

    Diagnosis of primary and secondary brain tumours and other focal intracranial mass lesions based on imaging procedures alone is still a challenging problem. Proton magnetic resonance spectroscopy ({sup 1}H-MRS) gives completely different information related to cell membrane proliferation, neuronal damage, energy metabolism and necrotic transformation of brain or tumour tissues. Our purpose was to evaluate the clinical utility of {sup 1}H-MRS added to MRI for the differentiation of intracranial neoplastic and non-neoplastic mass lesions. 176 mostly histologically verified lesions were studied with a constant clinically available single volume {sup 1}H-MRS protocol following routine MRI. 12 spectra (6.8%) were not of satisfactory diagnostic quality; 164 spectroscopic data sets were therefore available for definitive evaluation. Our study shows that spectroscopy added to MRI helps in tissue characterization of intracranial mass lesions, thereby leading to an improved diagnosis of focal brain disease. Non-neoplastic lesions such as cerebral infarctions and brain abscesses are marked by decreases in choline (Cho), creatine (Cr) and N-acetyl-aspartate (NAA), while tumours generally have elevated Cho and decreased levels of Cr and NAA. Gliomas exhibit significantly increased Cho and lipid formation with higher WHO tumour grading. Metastases have elevated Cho similar to anaplastic astrocytomas, but can be differentiated from high-grade gliomas by their higher lipid levels. Extra-axial tumours, i.e. meningiomas and neurinomas, are characterized by a nearly complete absence of the neuronal marker NAA. The additive information of {sup 1}H-MRS led to a 15.4%-higher number of correct diagnoses, to 6.2% fewer incorrect and 16% fewer equivocal diagnoses than with structural MRI data alone. (orig.)

    Syndesmosis injuries are rare, but very debilitating and frequently misdiagnosed. The purpose of this clinical commentary is to review the mechanisms of syndesmotic injuries, clinical examination methods, diagnosis, and management of the injuries. Cadaveric studies of the syndesmosis and deltoid ligaments are also reviewed for further understanding of stress transmission and the roles of different structures in stabilizing the distal syndesmosis. External rotation and excessive dorsiflexion of the foot on the leg have been reported as the most common mechanisms of injury. The injury is most often incurred by individuals who participate in skiing, football, soccer, and other sport activities played on turf. The external rotation and squeeze tests are reliable tests to detect this injury. The ability of imaging studies to assist in an accurate diagnosis may depend on the severity of the injury. The results of cadaveric studies indicate the importance of the deltoid ligament in maintaining stability of the distal tibiofibular syndesmosis and the congruency of the ankle mortise. Intervention programs with early rigid immobilization and pain relief strategies, followed by strengthening and balance training are recommended. Heel lift and posterior splint intervention can be used to avoid separation of the distal syndesmosis induced by excessive dorsiflexion of the ankle joint. Application of a rigid external device should be used with caution to prevent medial-lateral compression of the leg superior to the ankle mortise, thereby inducing separation of the distal syndesmosis articulation. Surgical intervention is an option when a complete tear of the syndesmotic ligaments is present or when fractures are observed.
