    Full Text Available Introduction. Intestinal parasitic infections are among the major public health problems in developing countries. Hence, it is significant to explore coinfection with intestinal parasites and pulmonary tuberculosis because coinfection increases the complexity of control and prevention of pulmonary tuberculosis and parasitic diseases. Objective. To assess the prevalence of intestinal parasites among pulmonary tuberculosis suspected patients. Method. Institutional based cross-sectional study was conducted at University of Gondar Hospital from March to May, 2017. Stool samples were taken from each participant and examined by direct microscopy and concentration technique. Descriptive statistics was performed and chi-square test was used to show the association between variables. P values of <0.05 were considered statistically significant. Results. Intestinal parasites were detected in 50 (19.6% among a total of 256 pulmonary tuberculosis suspected patients who were included in the study, whereas the prevalence of pulmonary tuberculosis was 16.8% (43/256. Pulmonary tuberculosis and intestinal parasite coinfection was detected in 5 (2.0% of the participants. The most prevalent intestinal parasites infection in this study was Ascaris lumbricoides, 15 (5.85%, followed by Entamoeba histolytica/dispar, 14 (5.46%, and Hookworm, 13 (5.1%. Conclusion. The prevalence of intestinal parasites and their coinfection rate with pulmonary tuberculosis among pulmonary tuberculosis suspected patients were considerable.

    Radiological findings of 87 cases of intestinal tuberculosis are analyzed and presented. The diagnosis was based on histopathology in 29 cases, and on clinical ground and radiological findings in 58 cases. The radio of male and female patients was 4:6, and peak incidence is between 10 and 30. Abdominal pain, diarrhea, weight loss, fever and general weakness are frequent symptoms, and tenderness of abdomen, ascites with abdominal distension, malnutrition and emaciation are frequent signs of the patients. Laboratory investigation reveal anemia, raised ESR, hypoalbuminaemia and positive occult blood reaction in the stool in most of the patients. Chest film show activity pulmonary tuberculosis in only 1/3 patients. There is no pathognomonic radiological findings in intestinal tuberculosis and their manifestations are protean, and differentiation from other inflammatory diseases and malignant tumors in gastrointestinal tract is very difficult on radiological ground alone. However, in patients with complaining vague abdominal symptoms and signs, the radiological diagnosis is most certain means in the decision of existence of organic lesion and suggestion of tuberculosis in the gastrointestinal tract and its extent as yet. Multiplicity of the lesion, involvement of adjacent organ such as peritoneum or mesenteric lymph nodes, typical nodularity or irregularity of mesenteric border and existence of active pulmonary tuberculosis are the suggestive findings of intestinal tuberculosis. In the diagnosis of inflammatory disease or malignant tumor of gastrointestinal tract, the possibility of tuberculosis should be borne in mind, and vice versa

    Full Text Available Intestinal tuberculosis is an uncommon presentation of tuberculosis (TB and has clinicopathological similarities with Crohn's disease. In regions where TB is endemic clinicians must aware of this condition and fully evaluate their patients when Crohn's disease is diagnosed. We recommend all pathologic specimens be evaluate effectively for TB.Smear,culture and PCR for Mycobacterium.tuberculosis from samples aside the pathological reviews help for better diagnosis. Here we present a case of intestinal tuberculosis which initially diagnosed as Crohn's disease but after starting immunosuppressive agents he presented with disseminated tuberculosis.

    Tuberculosis is a public health's problema in the world. Its incidence is increasing in our environment due to inmigration and the use of inmunosupressors. It's a systemic disease that can affect rarely the gastrointestinal tract. We should take into account the epidemiological and clinical context of each patient, because the differential diagnosis is broad. It can mimic with other diseases, such as Crohn's disease. We report a case of intestinal tuberculosis, and underline the importance of the differential diagnosis of these patients. Copyright © 2018 Elsevier España, S.L.U. All rights reserved.

    Gastrointestinal histoplasmosis (GIH) without pulmonary and bone marrow involvement is very rare worldwide. It can be misdiagnosed as intestinal tuberculosis or Crohn's disease. There are just few case reports of GIH in patients with a positive HIV antibody test. Here, we report a patient who presented to our hospital with repeated intestinal obstruction. The suspicious diagnosis was intestinal tuberculosis or Crohn's disease due to unspecific clinical manifestations and radiologic images. Our patient's HIV antibody test was negative. She had no medical prescriptions. Therefore, our differential diagnosis needed to include ileum histoplasmosis besides intestinal lymphoma, intestinal tuberculosis, and Crohn's disease. Finally, the patient was diagnosed with ileum histoplasmosis due to surgical resection. It is important to be aware of potential infectious diseases, such as ileum histoplasmosis, when making a differential diagnosis. Moreover, surgical resection might be the final approach for small-intestine stricture with fibrosis.

    Intestinal volvulus without malrotation is a rare disease that causes volvulus of the small intestine despite normal intestinal rotation and fixation. We encountered a neonate with this disease who developed early jaundice and was suspected to have a fetal onset. This patient was characterized by early jaundice complicating intestinal volvulus without malrotation and is considered to have exhibited reduced fetal movement and early jaundice as a result of volvulus, necrosis, and hemorrhage of the small intestine in the fetal period. If abdominal distention accompanied by early jaundice is noted in a neonate, intestinal volvulus without malrotation and associated intraabdominal hemorrhage should be suspected and promptly treated.

    Radiologic findings in 30 patients with intestinal tuberculosis and 10 patients with intestinal Behcet's disease, who had been diagnosed at Seoul National University Hospital during the recent 5 years, were analysed retrospectively to evaluate the radiologic differential diagnosis of the two diseases. Intestinal tuberculosis severely involved the cecum, the ileocecal valve, the distal ileum and colons, but Behcet's disease mainly involved the distal ileum and infrequently the ileocecal valve and the cecum. The ulcers in tuberculosis were usually multiple small barium collected areas among pseudopolyps, on the contrary, those in Behcet's disease were multiple, discrete, well marinated, geographic, ring-like deep penetrating or collar-button shaped. Intestinal tuberculosis tended to involved long segments of intestines, with severer mucosal irregularity and deformity of the ileocecal valve and the ascending colon in comparison with Behcet's disease. Mesenteric and/or peritoneal involvement were accompanied in 1/3 cases of intestinal tuberculosis, and active pulmonary tuberculosis or pleural effusion also in 1/3 cases of intestinal tuberculosis.

    Full Text Available Introduction: There is a need for a rapid and cost-effective technique for reliable diagnosis of tubercular lymphadenopathy, particularly in low-resource setting. In this study, we have used various diagnostic techniques including polymerase chain reaction (PCR to diagnose clinically suspected cases of tubercular lymphadenopathy and compared the results to see which of the techniques are more sensitive, specific, and cost-effective. Materials and Methods: All patients having swelling in the neck, axillary, and inguinal regions were recruited for the study. Sputum for acid-fast Bacillus (AFB, fine-needle aspiration cytology, excision biopsy, DNA-PCR, AFB smear of the same material was done as per standard protocol. Results: 32% patients have granulomas with necrosis, whereas 30% have acute suppurative lesions and 24% and 14% patients were having only granulomas and only necrosis, respectively. A significant difference was observed between the PCR-negative and positive cases with respect to their cytomorphologic features. Positive AFB and tuberculosis-PCR (TB-PCR results were significantly more common in the cases with chronic granulomatous inflammation in comparison to the cases showing chronic inflammation only. Sensitivity and specificity of TB-PCR were found to be 71.4% and 28.4%, respectively. Conclusion: PCR is a sensitive and rapid technique in the demonstration of Mycobacterium tuberculosis. It should be done in clinically suspected patients of tuberculous lymphadenopathy when their AFB stain is even negative.

    Intestinal tuberculosis is still common in developing countries. In 186 patients with intestinal tuberculosis, clinical features, radiological findings and complications were carefully recorded and compared with those from earlier studies with a view to study any possible changes after the liberal use of antitubercular drugs. Sixty two percent of the patients in the present series had had prior exposure to antitubercular drugs. The incidence of systemic symptoms like fever and anorexia, alternating diarrhoea and constipation, peritoneal and lymph node involvements and associated pulmonary lesions were less frequently observed. On the other hand, an indolent and complicated course with intestinal obstruction (47 %) and lower gastrointestinal bleeding (5.5 %) and frequent colonic involvement (19 %) often necessitating surgical intervention appeared to have become more frequent than reported in earlier series. Awareness of these changes in the clinical profile of intestinal tuberculosis should be helpful in the diagnosis and management of the condition. (author)

    Full Text Available Intestinal tuberculosis is a common clinical problem in India. The clinical features of this disease are nonspecific and can be very similar to Crohn's disease. Radiological evaluation of the small bowel has undergone a paradigm shift in the last decade. This long tubular organ that has traditionally been difficult to evaluate can now be well-visualized by some innovative imaging and endoscopic techniques. This article highlights the state-of-the-art evaluation of ulceroconstrictive diseases of the bowel and provides recommendations for the differentiation of intestinal tuberculosis from Crohn's disease.

    An accurate identification of different species of Mycobacterium provides to allow appropriate treatment for Mycobacterium tuberculosis infection. Beside that, drug resistance of M. tuberculosis strains to rifampin is not clearly understood in contributing to the spread of tuberculosis in Indonesia. To assess the molecular mechanism of rifampin resistance, a number of clinical specimens of M. tuberculosis were analyzed their molecular nature of a part of the rpoB gene using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) methods. DNA's extracted from sputum samples were amplified and 32 P-labeled by PCR with the specific primers and the product was analyzed their mutation conferring resistance by MDE gel electrophoresis. Of the 70 specimens tested, 57 specimens were positive for M. tuberculosis organism only, three specimens contained a mixture of M. tuberculosis and non tuberculosis mycobacteria (NTM), and 10 specimens were negative approved by Duplex PCR. Of these sixty DNA positive samples (thus the sensitivity of PCR was 85.71%), 5 (8.3%) of them suspected to contain mutations in rpoB which were associated with rifampin resistance. Even though the frequency of mutation was low, the results from our study clearly indicate that the molecular mechanism of rifampin resistance in M. tuberculosis isolates from Indonesia involves alterations in the rpoB gene. Molecular diagnosis by PCR which is fast and easy to perform is useful for early and rapid detection of TB in sputum specimen. (author)

    Background Tuberculosis is a highly contagious disease accounting for a high number of deaths in the developing countries; its control can be effectively achieved if individuals with the disease receive adequate and timely treatment. The objective of this study was to determine the factors associated with late presentation of suspects to tuberculosis management facilities in Dagoretti district in Nairobi, Kenya. Method A cross sectional study was conducted on patients aged 18 years and above attending TB clinics in Dagoretti District, Nairobi Kenya. A total of 426 TB suspects were interviewed. The study covered 8 clinics in Dagoretti district. Analysis was done using SPSS version 16.0 and Epi info version 6, this included Chi Square for Bivariate analysis and Binary Logistic Regression for Multivariate Analysis. Results Out of the 426 tuberculosis suspects, 248 (58.2%) suspects had delayed in seeking medical care. In Bivariate analysis male gender (P = 0.039, O.R = 1.51; 95% Confidence Interval; 1.00- 2.27), level of education (Primary class 5-8) (P = 0.001, O.R= 2.06; 95% C.I 1.34-3.19) and place of first medical care (drug store) (P= 0.013, O.R = 1.63; 95% C.I 1.09-2.46) were all significantly associated with late presentation. After multivariate logistic regression, gender (P = 0,019, OR = 1.6), level of education (p = 0.029, OR = 1.26) and place of first medical care (P= 0.01 OR = 1.27), were found to be significantly associated with late presentation. Conclusion This study shows that age, level of education and place of first medical care are the factors associated with late presentation of suspects to tuberculosis management facilities.

    We compared cortisol and thyroid hormone (T3 and T4) concentrations between tuberculosis (TB)-suspected (n=10) and healthy (n=10) elephants of Nepal. Whole blood was collected from captive elephants throughout Nepal, and TB testing was performed using the ElephantTB STAT-PAK ® and DPP VetTB ® serological assays that detect antibodies against Mycobacterium tuberculosis and M. bovis in elephant serum. Cortisol, T3 and T4 were quantified by competitive enzyme immunoassays, and the results showed no significant differences in hormone concentrations between TB-suspect and healthy elephants. These preliminary data suggest neither adrenal nor thyroid function is altered by TB disease status. However, more elephants, including those positively diagnosed for TB by trunk wash cultures, need to be evaluated over time to confirm results.

    This study is to prospectively evaluate the efficiency of sonography for volvulus diagnosis in neonates with clinically suspected intestinal malrotation.A total of 83 patients with suspected intestinal malrotation who underwent detailed abdominal sonography and upper gastrointestinal contrast study were included. Malrotation was characterized by inversion of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in sonographic examination. The "whirlpool sign" of Color Doppler Sonography was recognized as a characteristic for malrotation with volvulus. The degrees of rotation of the SMV winding around SMA were also detected by sonography. Surgery was performed in patients with sonography diagnosed malrotation.A total of 39 patients were sonographically diagnosed as malrotation which was subsequently confirmed by surgery. The sensitivity and positive predictive value of the sonographic diagnosis were both 100% (39/39). The sensitivity, specificity and accuracy of "whirlpool sign" for the detection of midgut volvulus were 95.2% (20/21), 88.9% (16/18), and 92.3% (36/39), respectively. Greater degrees of rotation (equal or greater than 720°) showed higher risk (odds ratio, 5.0; P intestinal necrosis occurrence.Sonography is more accurate in diagnosing suspected malrotation than upper gastrointestinal contrast study. Specific sonographic "whirlpool sign" related to volvulus may be used as a potential indicator for intestinal necrosis. In addition, sonography can exclude malrotation and may help the diagnosis of other diseases, such as annular pancreas and duodenal atresia.

    HIV testing of persons referred for tuberculosis diagnosis (TB suspects) is recommended by World Health Organization but is not a policy in India, where HIV prevalence among TB suspects has never been reported. The current Indian policy of offering HIV testing only to TB cases may limit opportunities for early HIV diagnosis and treatment. All adult TB suspects examined for diagnostic sputum microscopy in Mandya district (2 million population), in December 2010, were offered voluntary HIV counseling and testing. Participants were assessed for subsequent TB diagnosis. Of 1668 eligible TB suspects, HIV status was ascertained for 1539 (92%). Among these, 108 (7%) were HIV positive. Of the 108, 43 (40%) were newly diagnosed as HIV (ie, not previously known to have HIV infection). To detect a new case of HIV infection, the number needed to screen among TB patients was 13, as compared to an number needed to screen of 37 among "TB suspects not diagnosed as TB". Applied annually in 2010, HIV testing of TB suspects in 2010 could have identified approximately 534 newly diagnosed HIV cases, a 51% increase in district HIV case finding. Routine HIV testing of TB suspects was feasible and yielded a large number of HIV cases in absolute terms and would increase district HIV case finding by 51%. The number of patients needed to be HIV tested to find a previously undetected HIV case among TB suspects was greater than for TB cases but was potentially acceptable. Given heterogeneity of HIV epidemic in India, broader surveillance is required before national policy decision.

    To determine the prevalence and healthcare-seeking behavior of tuberculosis (TB) suspects in Middle and South Jordan. A community-based survey was carried out between June-September 2005, whereby 61,730 adult household members were inquired about the presence of persistent cough for more than three weeks to identify TB suspects. These adults were then interviewed and referred to the nearest health center for clinical and sputum smear examination. Of the 61,730 surveyed household members, 1,544 (2.51%) were identified as TB suspects, of these two were sputum smear positive pulmonary TB. The first action with the onset of symptoms was to visit the health centers. Reasons for timely seeking care were accessibility of the facilities and confidence in obtaining a cure, and obstacles were belief that symptoms would resolve and economic constraints in rural residents. Females, rural residents, expatriates, and using private means of transportation were predictors of delay in seeking care for more than three weeks. This study has set the baseline information about the prevalence of TB suspects in Jordan and their healthcare-seeking behavior that shows community preference to seek care at health centers. These should be upgraded and the health workers trained on suspect management to enhance the TB elimination efforts.

    2013-01-01

    The ratio between maximal small intestinal (SI) diameter and the height of the body of the fifth lumbar vertebra (L5) in radiographs has been reported as a diagnostic test in dogs with suspected intestinal obstruction. In order to assess the effect of the SI/L5 ratio on the accuracy of radiographic diagnosis of intestinal obstruction, lateral abdominal radiographs of 37 dogs with small intestinal obstruction and 48 nonobstructed dogs were mixed and examined independently by six observers who were unaware of the final diagnosis and who represented a range of experience. Observers first examined radiographs subjectively and stated the likelihood of obstruction (definitely not, probably not, equivocal, probably, definitely). Observers subsequently reexamined the radiographs, determined the SI/L5 ratio, and again stated the likelihood of obstruction. The most frequent cause of obstruction was foreign body (29/37, 78%). Dogs with SI obstruction had a significantly larger median SI/L5 ratio than nonobstructed dogs (P = 0.0002). Using an SI/L5 ratio of 1.7 for diagnosis of intestinal obstruction, sensitivity and specificity were 66%. Use of the SI/L5 ratio was not associated with increased accuracy of diagnosis for any observer, regardless of experience, hence this test may have no diagnostic impact. © 2013 Veterinary Radiology & Ultrasound.

    Full Text Available Objective To explore the application value of T-spot test of Mycobacterium tuberculosis infection (T-SPOT.TB on diagnosis and differential diagnosis of pulmonary tuberculosis. Methods From Apr. 2014 to Dec. 2016, 700 patients with suspected pulmonary tuberculosis were collected, venous blood (5ml was drawn off and sputum was collected from each patient separately for T-SPOT.TB and pathogens identification (including TB. Chest CT, bronchoscopy brush or biopsy histopathological examination were followed up, cultivation of My. tuberculosis and of common bacteria with sputum or lavage fluid when needed. T-SPOT.TB test was performed according to the kit instruction operation. 2.5×105 peripheral blood mononuclear cells (PBMCs were added into the pre- coated anti- human γ- interferon antibody, and co-incubated separately with two specific My. tuberculosis antigens, namely early secretory targeting 6 (ESAT-6 and culture filtration protein 10 (CFP-10, and then the spot forming cells (SFCs were counted. The gold standard for present study were set as follows: 1 My. tuberculosis smear positive or culture positive; 2 Clinical diagnosis (meet any one is positive. The efficacy of T-SPOT.TB on diagnosing active TB was observed, and then the optimal critical value for diagnosing active TB was determined. Patients diagnosed as active TB were divided into 4 subgroups: initial treatment group, retreatment group, smear or culture positive group, and smear or culture negative group. T-SPOT.TB was carried out to detect A and B antigen, and the difference of formed SFCs was then compared. The present study was approved by the Ethics Committee of Xinjiang Uygur Autonomous Region Chest Hospital. Results Of 700 cases suspected of pulmonary tuberculosis enrolled in present study, 528 out of 624 definite cases (84.6% were finally diagnosed as active tuberculosis (active TB group and 96 cases (15.4% were as without TB infection (non-TB group.

    Full Text Available Systemic imaging of patients with suspect ocular tuberculosis include chest X-rays and computed tomography (CT scans. Reports have suggested a role for 18 fluorodeoxyglucose-positron emission tomography/CT (FDG-PET/CT scans. We report on the clinical utility of 18 FDG PET/CT in two patients. Case 1: A 38-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active supraclavicular and chest lymph nodes. An aspiration cytology of the cervical lymph node revealed caseating granulomas suggestive of tuberculosis. Case 2: A 58-year-old female patient presented with recurrent anterior uveitis. A 18 FDG-PET scan revealed metabolically active lymph nodes in the neck. A biopsy of the cervical lymph node revealed epithelioid granulomas suggestive of tuberculosis. Both patients were started on standard antitubercular therapy with a subsequent marked reduction of activity. PET/CT scans may suggest the sites of safe high-yield biopsies.

    In the structure of tuberculosis morbidity, urogenital tuberculosis (UGT) ranks second or third only to pulmonary tuberculosis. Every fourth patient has the stage of cavern formation at first presentation. Seventy five percent of nephrotuberculosis cases co-occur with nonspecific pyelonephritis, which excludes "sterile pyuria". We aimed to determine the microbial spectrum of urine and gonadal appendages in patients with suspected UGT and to investigate the susceptibility of the isolated microorganisms to the main antibacterial drugs. The study investigated the spectrum of pathogenic microflora isolated from patients admitted to the urogenital clinic of the TB Research Institute from January 1, 2012 to September 30, 2016 to rule out UGT. Microorganism species were identified by time-of-flight mass spectrometry using the microbiological analyzer Phoenix 100 (Becton Dickinson, USA). Antibiotic resistance was determined using the Phoenix 100 microbiological analyzer (Becton Dickinson, USA). A total of 3004 bacteriological tests for nonspecific microflora were performed during the analyzed period. In the structure of pathogens, E. coli comprised about half of the cases thus confirming its role as the leading uropathogen. Only piperacillin/tazobactam and nitrofurantoin provided relatively plausible antimicrobial resistance rates, for other antibacterial drugs the rates of susceptible strains progressively decreased and by 2016 dropped to 40% and lower. Our findings cannot be extrapolated to the entire population since patients presenting for differential diagnosis receive multiple courses of treatment with various antibacterial drugs, which led to the selection of resistant strains. The findings emphasize the need for a strict selection of antibiotics for urogenital infection empirical therapy. In the absence of response, the patient should be immediately examined for tuberculosis using molecular and genetic diagnostic techniques.

    Radiographic demonstration of mediastinal lymphadenopathy is important for the diagnosis of pulmonary tuberculosis (PTB). Plain radiographs are unreliable for this and CT, which is relatively more expensive and carries a high radiation burden, remains the gold standard. No studies correlating the presence of axillary with mediastinal lymphadenopathy have been reported. Such a correlation would allow for clinical or ultrasound diagnosis of PTB via the axilla. To correlate the presence of axillary lymphadenopathy with mediastinal lymphadenopathy in children with suspected PTB. CT scans were performed and reviewed in 100 children (prospectively recruited) with suspected PTB. The axilla and mediastinum were reviewed separately by covering the non-relevant sections on the CT scans prior to reading. Only nodes greater than 1 cm were regarded as pathological. Mediastinal lymphadenopathy was present in 46% of children; 70% had lymphadenopathy in either axilla. Bilateral axillary lymphadenopathy was identified in 47%. Axillary lymphadenopathy showed a sensitivity of 74% and a specificity of 33% for the presence of mediastinal adenopathy. Bilateral axillary adenopathy had a sensitivity of 50% and a specificity of 56%. Axillary lymphadenopathy has a moderate sensitivity and low specificity for the presence of mediastinal and hilar lymphadenopathy in children with suspected PTB. Further research should be aimed at correlating ultrasound-detected axillary lymphadenopathy with FNA results in children. (orig.)

    In Fiji, patients with suspected pulmonary tuberculosis (PTB) currently submit three sputum specimens for smear microscopy for acid-fast bacilli, but there is little information about how well this practice is carried out. A cross-sectional retrospective review was carried out in all four TB diagnostic laboratories in Fiji to determine among new patients presenting with suspected PTB in 2011: the quality of submitted sputum; the number of sputum samples submitted; the relationship between quality and number of submitted samples to smear-positivity; and positive yield from first, second and third samples. Of 1940 patients with suspected PTB, 3522 sputum samples were submitted: 997 (51.4%) patients submitted one sample, 304 (15.7%) patients submitted two samples and 639 (32.9%) submitted three samples. Sputum quality was recorded in 2528 (71.8%) of samples, of which 1046 (41.4%) were of poor quality. Poor quality sputum was more frequent in females, inpatients and children (0-14 years). Good quality sputum and a higher number of submitted samples positively correlated with smear-positivity for acid-fast bacilli. There were 122 (6.3%) patients with suspected PTB who were sputum smear positive. Of those, 89 had submitted three sputum samples: 79 (89%) were diagnosed based on the first sputum sample, 6 (7%) on the second sample and 4 (4%) on the third sample. This study shows that there are deficiencies in the practice of sputum smear examination in Fiji with respect to sputum quality and recommended number of submitted samples, although the results support the continued use of three sputum samples for TB diagnosis. Ways to improve sputum quality and adherence to recommended guidelines are needed.

    Full Text Available BACKGROUND: Perceived stigma and lack of awareness could contribute to the late presentation and low detection rate of tuberculosis (TB. We conducted a study in rural southwest Ethiopia among TB suspects to assess knowledge about and stigma towards TB and their health seeking behavior. METHODS: A community based cross sectional survey was conducted from February to March 2009 in the Gilgel Gibe field research area. Any person 15 years and above with cough for at least 2 weeks was considered a TB suspect and included in the study. Data were collected by trained personnel using a pretested structured questionnaire. Logistic regression analysis was done using SPSS 15.0 statistical software. RESULTS: Of the 476 pulmonary TB suspects, 395 (83.0% had ever heard of TB; "evil eye" (50.4% was the commonly mentioned cause of TB. Individuals who could read and write were more likely to be aware about TB [(crude OR = 2.98, (95%CI: 1.25, 7.08] and more likely to know that TB is caused by a microorganism [(adjusted OR = 3.16, (95%CI: 1.77, 5.65] than non-educated individuals. Males were more likely to know the cause of TB [(adjusted OR = 1.92, (95%CI: 1.22, 3.03] than females. 51.3% of TB suspects perceived that other people would consider them inferior if they had TB. High stigma towards TB was reported by 199(51.2%. 220 (46.2% did not seek help for their illness. Individuals who had previous anti-TB treatment were more likely to have appropriate health seeking behavior [(adjusted OR = 3.65, (95%CI: 1.89, 7.06] than those who had not. CONCLUSION: There was little knowledge about TB in the Gilgel Gibe field research area. We observed inappropriate health seeking behavior and stigma towards TB. TB control programs in Ethiopia should educate rural communities, particularly females and non-educated individuals, about the cause and the importance of early diagnosis and treatment of TB.

    Full Text Available Objectives: Since melioidosis mimics tuberculosis clinically and radiologically, there is a need for a rapid diagnostic method to help the clinician to initiate appropriate antimicrobial treatment in order to prevent mortality. Our objective was to standardize a nested PCR for B. pseudomallei and its detection in pulmonary and extra pulmonary samples from patients with suspected TB. Materials and Methods: Archived pulmonary and extra pulmonary samples which were negative for M. tuberculosis smear microscopy, culture and PCR were included in the study. DNA was extracted (QiAmp Blood DNA kit, Qiagen, Germany and conventional nested PCR were carried out to detect the presence of 16S-23S spacer region of B. pseudomallei. The DNA was detected by 2% agarose gel electrophoresis and the presence of 251 bp was considered positive. Results: A total of 55 samples were tested, out of which 9 (16.3% samples tested positive for Burkholderia pseudomallei using nested PCR, which included 5 extra pulmonary and 4 pulmonary samples. These patients belonged to Tamil Nadu 8 (88.8% and West Bengal 1 (11.1% both of which are rice growing regions. Among the nine patients who were positive for B. pseudomallei by nested PCR, 2 (22% were receiving empirical anti-tubercular treatment (ATT. Also, these patients encountered co-morbid condition like renal failure, malignancy, diabetes and co-infection with HIV. Conclusion: We suggest that the patients with symptoms suggestive of both pulmonary and extra pulmonary tuberculosis should be routinely tested for Burkholderia pseudomallei by molecular methods for timely initiation of appropriate therapy and avoid unnecessary exposure to ATT.

    Full Text Available The genus Mycobacterium contains more than 150 species. Non-tuberculosis mycobacteria (NTM often cause extrapulmonary and pulmonary disease. Mycobacteria detection at species level is necessary and provides useful information on epidemiology and facilitates successful treatment of patients. This retrospective study aimed to determine the incidence of the NTM isolates and Mycobacterium tuberculosis (Mtb in clinical specimens collected from Iranian patients during February 2011–December 2013, by PCR–restriction fragment length polymorphism analysis (PRA of the hsp65 gene. We applied conventional biochemical test and hsp65–PRA identification assay to identify species of mycobacteria in specimens from patients suspected of having mycobacterial isolates. This method was a sensitive, specific and effective assay for detecting mycobacterial species and had a 100% sensitivity and specificity for Mtb and Mycobacterium avium complex (MAC species. Using PRA for 380 mycobacterial selected isolates, including 317 Mtb, four Mycobacterium bovis and of the 59 clinical isolates, the most commonly identified organism was Mycobacterium kansasii (35.6%, followed by Mycobacterium simiae (16.9%, Mycobacterium gordonae (16.9%, Mycobacterium fortuitum (5.1%, Mycobacterium intracellulare (5.1%, Mycobacterium avium (5.1%, Mycobacterium scrofulaceum (3.4%, Mycobacterium gastri (3.4%, Mycobacterium flavescens (3.4%, Mycobacterium chelonae (3.4% and Mycobacterium nonchromogenicum (1.7%. PRA method, in comparison with classical methods, is rapid, useful and sensitive for the phylogenetic analysis and species detection of mycobacterial strains. Mycobacterium kansasii is the most common cause of infection by NTM in patients with non-HIV and HIV which demonstrated a high outbreak and diversity of NTM strains in our laboratory.

    There is growing evidence that tobacco smoking is an important risk factor for tuberculosis (TB). There are no data validating the accuracy of self-reported smoking in TB patients and limited data about the prevalence of smoking in TB patients from high-burden settings. We performed a cross-sectional analysis of 500 patients with suspected TB in Cape Town, South Africa. All underwent comprehensive diagnostic testing. The accuracy of their self-reported smoking status was determined against serum cotinine levels. Of the 424 patients included in the study, 56 and 60% of those with active and latent TB infection (LTBI), respectively, were current smokers. Using plasma cotinine as a reference standard, the sensitivity of self-reported smoking was 89%. No statistically significant association could be found between smoking and active TB or LTBI. In Cape Town, the prevalence of smoking among patients with suspected and confirmed TB was much higher than in the general South African population. Self-reporting is an accurate measure of smoking status. These results suggest the need to actively incorporate tobacco cessation programmes into TB services in South Africa.

    Recently reports of cervical tuberculous lymphadenitis and oropharyngeal tularemia which are the most common infectious causes of granulomatous lymphadenitis, have been significantly increased in Turkey. The differentiation of cervical tuberculous lymphadenitis and oropharyngeal tularemia is usually confusing on the basis of clinical and histopathological findings. Thus, in tularemia endemic areas, the patients are more commonly evaluated in terms of tularemia lymphadenitis leaving tuberculosis out. The aim of this study was to investigate the presence of Mycobacterium tuberculosis in cervical lymph node aspirates, obtained from tularemia suspected cases. A total of 105 oropharyngeal tularemia-suspected cases which were found negative for Francisella tularensis by bacteriological (culture), molecular (PCR) and serological (microagglutination) methods, were included in the study. The samples had been previously studied at National Tularemia Reference Laboratory, Turkish Public Health Institution, between 2009-2011. The study samples were evaluated in terms of M.tuberculosis by culture and real-time PCR (rtPCR) methods in the National Tuberculosis Reference Laboratory. Both Lowenstein-Jensen (LJ) medium and liquid-based MGIT (BD, USA) automated culture system were used for mycobacterial culture. Samples that yielded mycobacterial growth were identified as M.tuberculosis by immunochromotographic test (BD, USA). The lymph node aspirates of 65 patients who were F.tularensis PCR negative but antibody positive, were used as the control group. As a result, M.tuberculosis was found to be positive in 9 (8.6%) of 105 tularemia-negative lymph node aspirates, sent to our laboratory from different geographic regions for the investigation of tularemia. Six of the M.tuberculosis positive cases were male and the age range of the patients was 26-85 years. The presence of M.tuberculosis was detected only by culture in two samples, only by rtPCR in five samples and both by culture and

    Background. The Xpert MTB/RIF (Xpert) assay is a rapid nucleic acid amplification test widely used in settings of high tuberculosis prevalence to detect tuberculosis as well as rpoB mutations associated with rifampin resistance. Data are needed on the diagnostic performance of Xpert in lower-prevalence settings to inform appropriate use for both tuberculosis detection and the need for respiratory isolation. Methods. Xpert was compared to 2 sputum samples, each evaluated with acid-fast bacilli (AFB) smear and mycobacterial culture using liquid and solid culture media, from participants with suspected pulmonary tuberculosis from the United States, Brazil, and South Africa. Results. Of 992 participants enrolled with evaluable results, 22% had culture-confirmed tuberculosis. In 638 (64%) US participants, 1 Xpert result demonstrated sensitivity of 85.2% (96.7% in participants with AFB smear-positive [AFB+] sputum, 59.3% with AFB smear-negative [AFB–] sputum), specificity of 99.2%, negative predictive value (NPV) of 97.6%, and positive predictive value of 94.9%. Results did not differ between higher- and low-prevalence settings. A second Xpert assay increased overall sensitivity to 91.1% (100% if AFB+, 71.4% if AFB–), with specificity of 98.9%. In US participants, a single negative Xpert result predicted the absence of AFB+/culture-positive tuberculosis with an NPV of 99.7%; NPV of 2 Xpert assays was 100%, suggesting a role in removing patients from airborne infection isolation. Xpert detected tuberculosis DNA and mutations associated with rifampin resistance in 5 of 7 participants with rifampin-resistant, culture-positive tuberculosis. Specificity for rifampin resistance was 99.5% and NPV was 98.9%. Conclusions. In the United States, Xpert testing performed comparably to 2 higher-tuberculosis-prevalence settings. These data support the use of Xpert in the initial evaluation of tuberculosis suspects and in algorithms assessing need for respiratory isolation

    Between 1 January 2010 and 31 December 2016, a total of 14 U.S. and international military personnel in training at Joint Base San Antonio-Lackland, TX, were hospitalized due to suspected pulmonary tuberculosis (TB); of these, five personnel were diagnosed with active TB disease. Only one TB case had pulmonary symptoms, but these symptoms were not suggestive of TB. The incidence rate in the training population was 1.89 per 100,000 population (95% CI: 0.81, 4.42), with a higher rate when restricted to international military students attending the Defense Language Institute English Language Center. No instances of TB transmission were identified. The variety of atypical presentations and their resulting diagnostic and public health challenges prompted this retrospective review of all hospitalized cases. This case series highlights both the importance of a high index of clinical suspicion when TB is being considered in close congregate settings as well as the risk of overreliance on acid-fast bacilli staining and nucleic acid amplification testing for ruling out active pulmonary disease in young, otherwise healthy trainees. Practical solutions are suggested.

    Rapid diagnosis of pulmonary tuberculosis (TB) is critical for timely initiation of treatment and interruption of transmission. Yet, despite recent advances, many patients remain undiagnosed. Culture, usually considered the most sensitive diagnostic method, is sub-optimal for paucibacillary disease. We evaluated the Totally Optimized PCR (TOP) TB assay, a new molecular test that we hypothesize is more sensitive than culture. After pre-clinical studies, we estimated TOP's per-patient sensitivity and specificity in a convenience sample of 261 HIV-infected pulmonary TB suspects enrolled into a TB diagnostic study in Mbarara, Uganda against MGIT culture, Xpert MTB/RIF and a composite reference standard. We validated results with a confirmatory PCR used for sequencing M. tuberculosis. Using culture as reference, TOP had 100% sensitivity but 35% specificity. Against a composite reference standard, the sensitivity of culture (27%) and Xpert MTB/RIF (27%) was lower than TOP (99%), with similar specificity (100%, 98% and 87%, respectively). In unadjusted analyses, culture-negative/TOP-positive patients were more likely to be older (PDNA sequencing exhibit differential growth in culture. These findings suggest that the TOP TB assay is accurately detecting M. tuberculosis DNA in the sputum of culture-negative tuberculosis suspects. Our results require prospective validation with clinical outcomes. If the operating characteristics of the TOP assay are confirmed in future studies, it will be justified as a "TB rule out" test.

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

    Full Text Available Nigeria is ranked in the top five countries for tuberculosis deaths worldwide. This study investigated the mycobacterial agents associated with presumptive clinical pulmonary tuberculosis (TB in Nigeria and evaluated the pattern and frequency of mycobacterial infections over twelve calendar months period.Sputum samples from 1,603 consecutive new cases with presumptive diagnosis of TB were collected from August 2010 to July 2011. All sputum samples were incubated for detection of mycobacterial growth and those with positive acid fast bacilli (AFB growth were tested to detect mycobacterium tuberculosis (MTB complex and characterized to differentiate between MTB complex species. Cultures suggestive of Non-tuberculous mycobacterial infections (NTM were sub-cultured and characterized.Of the 1,603 patients screened, 444 (28% culture-positive cases of pulmonary tuberculosis were identified. Of these, 375 (85% were due to strains of MTB complex (354 cases of M. tuberculosis, 20 M. africanum and one case of M. bovis and 69 (15% were due to infection with NTM. In contrast to the MTB complex cases, the NTM cases were more likely to have been diagnosed during the calendar months of the Harmattan dust season (OR = 2.34, 1.28-4.29; p = 0.01, and aged older than 35 years (OR = 2.77, 1.52-5.02, p = 0.0007, but less likely to have AFB identified on their sputum smear (OR = 0.06, 0.02-0.14, p<0.0001. Among those with NTM infection, cases 35 years or younger were more likely to have co-infection with HIV (3.76, 1.72-8.22; p = 0.0009 compared to those older than 35 years.The high proportion of younger patients with clinical pulmonary TB due to NTM and co-infection with HIV and the likely role of the seasonal dust exposure in the occurrence of the disease, present novel public health challenges for prevention and treatment.

    Full Text Available Background: The interface between tuberculosis (TB and Crohn's disease (CD is relevant as TB complicates both the diagnosis and management of CD. Aim: This study aimed to identify the distinctive characteristics of ileocaecal and colonic TB (C-TB and colonic CD (C-CD at colonoscopy and to correlate the colonoscopy findings with histology. Materials and Methods: This prospective study included consecutive patients presenting with classical symptoms of TB or CD. The colonoscopic findings were compared with histology, which was taken as gold standard. Appropriate statistical tests were applied. Results: Fifty-eight individuals fulfilled the inclusion criteria. Nine and 16 patients with C-TB and C-CD, respectively, had histological confirmation of respective diagnosis. In 33 specimens, the histological diagnosis was inconclusive. The sensitivity of colonoscopy for diagnosing C-TB was high at 88.9% (95% confidence interval [CI]: 51.8–99.7. It was 50% (95% CI: 24.7–75.4 for CD. The reverse was true for CD whose specificity was high at 71.4% (95% CI: 55.3–84.3 and low for TB at 46.9% (95% CI: 32.5–61.7. All the patients diagnosed as confirmed CD or TB responded well to respective treatment. Six of the thirty patients with failed response to anti-TB treatment required surgery or change in treatment after 2 months. Conclusion: Colonoscopic findings of isolated ileal involvement, aphthous ulcer, cobble stoning, long-segment strictures, skip lesions and perianal involvement favored a diagnosis of CD. Correlation of colonoscopy with histology is poor for both CD and TB. The accuracy, sensitivity and specificity of colonoscopy were better and superior for the diagnosis of CD, than in the diagnosis of TB.

    Full Text Available Studies in the northern part of Ethiopia showed high prevalence of undiagnosed cluster of tuberculosis cases within the community which demanded an investigation of the health care seeking behaviour of tuberculosis suspects. A community-based cross-sectional study was conducted in Lay Armachiho district, Northwest Ethiopia. Individuals who had cough for at least two weeks and aged greater than or equal to 15 years were included in the study. Data were collected by interview using pretested and structured questionnaire. Logistic regression was computed and adjusted odds ratio with 95% confidence interval was calculated. Out of the total population surveyed (29, 735, 663 (2.2% individuals were found to be pulmonary tuberculosis suspects. Majority of the suspects reported that they had visited a modern health care facility. Those aged 15 to 34 and aged 35–54 had secondary educational level and above; those who were civil servants, those who were farmers, those who had previous history of tuberculosis treatment, and those who perceived that they were sick were more likely to visit a modern health care facility. The proportion of respondents who had taken traditional measures was found to be higher than some other districts. Improving the socioeconomic status of the community is recommended.

  13. Use of a molecular diagnostic test in AFB smear positive tuberculosis suspects greatly reduces time to detection of multidrug resistant tuberculosis.

    Full Text Available The WHO has recommended the implementation of rapid diagnostic tests to detect and help combat M/XDR tuberculosis (TB. There are limited data on the performance and impact of these tests in field settings.The performance of the commercially available Genotype MTBDRplus molecular assay was compared to conventional methods including AFB smear, culture and drug susceptibility testing (DST using both an absolute concentration method on Löwenstein-Jensen media and broth-based method using the MGIT 960 system. Sputum specimens were obtained from TB suspects in the country of Georgia who received care through the National TB Program.Among 500 AFB smear-positive sputum specimens, 458 (91.6% had both a positive sputum culture for Mycobacterium tuberculosis and a valid MTBDRplus assay result. The MTBDRplus assay detected isoniazid (INH resistance directly from the sputum specimen in 159 (89.8% of 177 specimens and MDR-TB in 109 (95.6% of 114 specimens compared to conventional methods. There was high agreement between the MTBDRplus assay and conventional DST results in detecting MDR-TB (kappa = 0.95, p<0.01. The most prevalent INH resistance mutation was S315T (78% in the katG codon and the most common rifampicin resistance mutation was S531L (68% in the rpoB codon. Among 13 specimens from TB suspects with negative sputum cultures, 7 had a positive MTBDRplus assay (3 with MDR-TB. The time to detection of MDR-TB was significantly less using the MTBDRplus assay (4.2 days compared to the use of standard phenotypic tests (67.3 days with solid media and 21.6 days with broth-based media.Compared to conventional methods, the MTBDRplus assay had high accuracy and significantly reduced time to detection of MDR-TB in an area with high MDR-TB prevalence. The use of rapid molecular diagnostic tests for TB and drug resistance should increase the proportion of patients promptly placed on appropriate therapy.

    Tuberculosis (TB) is a serious health problem in Papua New Guinea (PNG) with an estimated 30000 new cases and 3800 deaths each year. In the Balimo region of the Western Province, diagnosis relies on clinical manifestations and on the microscopic detection of acid-fast bacilli (AFB) in sputum smears, a technique with limited sensitivity. A molecular diagnosis assay targeting DNA extracted from archived sputum smear slides collected from the Balimo region (2012-2014) was conducted, without the need for a viable culture. The presence of Mycobacterium sp on 1162 slides prepared from 345 sputum samples was assessed using a real-time PCR (qPCR) approach. The qPCR technique identified the presence of mycobacteria in 35.4% of the smear slides and 59.7% of the tested sputum samples. Poor agreement was observed between the two diagnosis methods (smear AFB microscopy versus qPCR), with 100 AFB-positive sputum samples compared to 206 qPCR-positive sputum samples overall. Treatment was initiated in 90.2% of the smear-positive cases. Unnecessary treatment of 'false-positive' TB cases (AFB-negative/qPCR-negative) was very low (8.6%) and was even lower when the nine patients diagnosed with extrapulmonary TB were excluded from the analysis. However, the prevalence of false-negatives (AFB-negative/qPCR-positive) was high (28.5%). Undetected smear-negative TB is occurring in the Balimo region of PNG, as well as some unnecessary empirical treatment. Molecular methods of diagnosis could greatly reduce the frequency of inappropriate clinical assessment, as well as providing point-of-care diagnosis. This may provide substantial patient and programmatic benefits, including lowering the economic burden on patients from rural areas seeking medical diagnosis in Balimo.

    Full Text Available The incidence of non-tuberculous mycobacteria (NTM-related death has increased globally recently. To obtain information of the species and characterization of pathogens involved in NTM pulmonary infection in Southern-central China, we identified 160 non-tuberculous infection cases from 3995 acid-fast bacilli (AFB-positive tuberculous suspects. We then randomly selected 101 non-tuberculous patients, isolated bacteria from their sputa and genotyped the pathogens using the 16S rRNA gene and 16S-23S rRNA internal transcribed spacer sequences. M. intracellulare (32.67%, 33/101, M. abscessus (32.67%, 33/101 and M. fortuitum (7.92%, 8/101 are identified in these isolates. Surprisingly, non-mycobacteria including Gordonia (8.91%, 9/101, Nocardia (5.94%, 6/101 and Tsukamurella (0.99%, 1/101 are also discovered, and the case of Tsukamurella pulmonis infection is first discovered in Southern-central China. Moreover, species of M. mucogenicum group, M. chubuense, M. kansasii, M. gastri, M. avium, M. porcinum and M. smegmatis are identified. In addition, nine immune compromised cases (8.91%, 9/101, including type two diabetes mellitus and HIV/AIDS are found to be infected with non-tuberculous bacteria. This study revealed the distribution and characteristics of non-tuberculous AFB pathogen infection occurred in Southern-central China, and suggested that physicians should be alert of the emerging of NTM and non-mycobacteria infection in AFB positive cases and take caution when choosing chemotherapy for tuberculosis-like pulmonary infections. Generally, this study may help with the development of new strategy for the diagnosis and treatment of mycobacterial infection.

    Full Text Available Mycobacterium avium subsp. avium (Maa is an intracellular pathogen belonging to the Mycobacterium avium-intracellulare complex (MAC. Reservoirs of MAC are the natural environment, wildlife and domestic animals. In adult bovine, MAC infections are typically caused by Mycobacterium avium subsp. paratuberculosis (Map. Maa infections in bovine are rarely reported but may cause clinical disease and pathological lesions similar to those observed in paratuberculosis or those induced by members of the Mycobacterium tuberculosis complex (MTBC. Therefore, differentiation of MAC from MTBC infection should be attempted, especially if unusual mycobacterial lesions are encountered. Four veal calves from a fattening farm dying with clinical signs of otitis media, fever, and weight loss were submitted for necropsy. Samples from affected organs were taken for histologic investigation, bacteriologic culture, and bacterial specification using PCR. Macroscopic thickening of the intestinal mucosa was induced by granulomatous enteritis and colitis. Intracytoplasmic acid-fast bacteria were detected by Ziehl-Neelsen stains and PCR revealed positive results for Mycobacterium avium subsp. avium. Clinical and pathological changes of Maa infection in veal calves had features of Mycobacterium avium subsp. paratuberculosis and the MTBC. Therefore, Mycobacterium tuberculosis complex infection should be considered in cases of granulomatous enteritis in calves.

    Combining a polymerase chain reaction (PCR) test with bronchoscopy is frequently performed to allow a rapid diagnosis of smear-negative pulmonary tuberculosis (PTB). However, limited data are available concerning clinical judgment in patients with suspected PTB and AFB smear- and PCR-negative bronchial aspirates (BA). The present study evaluated the usefulness of whole-blood QuantiFERON-TB Gold In-Tube (QFT) testing in these patients. Of 166 patients with suspected PTB who had undergone bronchoscopy because of smear-negative sputum or inadequate sputum production, 93 (56%) were diagnosed with culture-positive PTB. Seventy-four patients were either AFB smear- or PCR-positive. In the 75 patients whose BA AFB smear and PCR results were both negative, 19 were finally diagnosed with PTB by culture. The QFT test had a negative predictive value of 91% for PTB. The QFT test may be useful for excluding PTB in patients with suspected PTB whose BA AFB smear and PCR results are both negative.

    Full Text Available Both pulmonary tuberculosis (PTB and intestinal helminth infection (IHI affect millions of individuals every year in China. However, the national-scale estimation of prevalence predictors and prevalence maps for these diseases, as well as co-endemic relative risk (RR maps of both diseases' prevalence are not well developed. There are co-endemic, high prevalence areas of both diseases, whose delimitation is essential for devising effective control strategies. Bayesian geostatistical logistic regression models including socio-economic, climatic, geographical and environmental predictors were fitted separately for active PTB and IHI based on data from the national surveys for PTB and major human parasitic diseases that were completed in 2010 and 2004, respectively. Prevalence maps and co-endemic RR maps were constructed for both diseases by means of Bayesian Kriging model and Bayesian shared component model capable of appraising the fraction of variance of spatial RRs shared by both diseases, and those specific for each one, under an assumption that there are unobserved covariates common to both diseases. Our results indicate that gross domestic product (GDP per capita had a negative association, while rural regions, the arid and polar zones and elevation had positive association with active PTB prevalence; for the IHI prevalence, GDP per capita and distance to water bodies had a negative association, the equatorial and warm zones and the normalized difference vegetation index had a positive association. Moderate to high prevalence of active PTB and low prevalence of IHI were predicted in western regions, low to moderate prevalence of active PTB and low prevalence of IHI were predicted in north-central regions and the southeast coastal regions, and moderate to high prevalence of active PTB and high prevalence of IHI were predicted in the south-western regions. Thus, co-endemic areas of active PTB and IHI were located in the south-western regions of

    The purpose of this report is to present an update on the manifestations and management of ocular tuberculosis. Tuberculosis affects one-third of the world's population. The incidence of tuberculosis has increased with the increase in the HIV infected population. Following a resurgence of the disease in the US, the incidence has recently declined. Patients may develop scleritis that can be focal, nodular or diffuse with or without keratitis. Anterior granulomatous uveitis may occur. The posterior segment reveals vitritis, choroiditis, and can mimic serpiginous choroiditis and other entities. Patients who are immunosuppressed or HIV infected may develop active mycobacterial disease in the eye leading to rapid destruction of the ocular structures. The diagnosis of ocular tuberculosis is made by isolation of Mycobacterium tuberculosis on Löwestein-Jensen medium or by PCR. The diagnosis is supported by the clinical findings, imaging techniques including optical coherence tomography, fluorescein angiography, indocyanine green and ultrasonography. Tuberculin skin test helps to confirm the diagnosis. Ocular tuberculosis may occur in the absence of pulmonary disease. Patients present with a spectrum of clinical signs. The disease may mimic several clinical entities. Early diagnosis and prompt treatment of ocular tuberculosis may prevent ocular morbidity and blindness.

    Full Text Available En la actualidad la incidencia de la tuberculosis ha aumentado. El Mycobacterium tuberculosis infecta frecuentemente a las personas con SIDA, debido a que en estos pacientes hay una reducción de la resistencia mediada por células T, lo que propicia que este bacilo pueda desarrollar la enfermedad con una frecuencia superior a la de las personas sanas. La transmisión de la enfermedad puede ser por vía directa, de un individuo afectado a otro, fundamentalmente por las gotitas de saliva que contengan a este microorganismo, o por vía indirecta por la inhalación del bacilo que se puede encontrar por meses en los objetos de uso diario, debido a su gran resistencia. Las micobacterias que producen tuberculosis en el hombre inmunocompetente son la Mycobacterium tuberculosis y la bovis, otros tipos pueden provocar tuberculosis en individuos inmunocomprometidos. La patogenicidad de este bacilo está relacionada con su capacidad para escapar de la destrucción inducida por los macrófagos y para provocar hipersensibilidad de tipo retardado. Esta enfermedad tiene muy pocas manifestaciones bucales, lo que se observa generalmente es una úlcera que toma como asiento fundamental el dorso de la lengua. La tuberculosis amenaza con convertirse en una enfermedad incurable por la deficiente administración de los programas contra ésta, por lo que la OMS plantea para su detección y tratamiento el DOTS (tratamiento observado directamente, de corta duración que comienza a tener resultados satisfactorios, aunque en el último quinquenio, el 88 % de los pacientes que se estimaban como infectados por tuberculosis no recibieron DOTS.At present, the incidence of tuberculosis is on the rise.

    It is known that cholesterol plays a key role for Mycobacterium tuberculosis (Mtb) adaptation and survival within the host, thus contributing to the establishment of dormancy. It has been extensively demonstrated that fatty acids are the main energy source of Mtb during infection and dormancy, and it has been proposed that these molecules are implicated in reactivation of bacilli from a dormant state. We used in vitro models to analyze Mtb gene expression during dormancy and reactivation when fatty acids and cholesterol are the unique carbon source in the media. Our results suggest that cholesterol might function as a signal to trigger Mtb expression of some genes required for stress protection earlier than the one induced by fatty acids alone, indicating that cholesterol is very favorable for its development. This process is so conducive that cholesterol-adapted bacilli can reactivate their growth after NRP2 dormancy state even 10 min post ventilation. Thus, we hypothesize that cholesterol is not only involved in Mtb dormancy but that it also plays a critical role for favorable and almost immediate reactivation from an in vitro long-lasting dormant state induced by hypoxia.

    Sputum culture is the gold standard for diagnosis of pulmonary tuberculosis (PTB). Although mostly used for research, culture is recommended by the World Health Organization for TB diagnosis among HIV infected smear negative PTB suspects. Even then, the number of sputum samples required remains unspecified. Here, we determined the Incremental Yield (IY) and number of samples required to diagnose an additional PTB case upon second and third serial sputum culture. This was a cross sectional study done between January and March 2011. Serial sputum samples were provided by participants within two days and cultured using Lowenstein Jensen (LJ) and Mycobacteria Growth Indicator Tube (MGIT) methods. A PTB case was defined as a positive culture on either one or both methods. The IY from the second and third serial cultures was determined and the reciprocal of the product of the fractions of IY provided the number of samples required for an additional PTB case. Of the 170 smear negative PTB suspects, 62 (36.5%) met the case definition. The IY of the second sample culture was 12.7%, 23.6% and 12.6% and for the third sample culture was 6.8%, 7.5% and 7.3% with LJ, MGIT and LJ or MGIT, respectively. The number of samples required for an additional PTB case and 95% CI upon the second sample culture were 29.9 (16.6, 156.5), 11.3 (7.6, 21.9) and 20.8 (12.5, 62.7); while for the third sample culture were 55.6 (26.4, 500.4), 35.7 (19.0, 313.8) and 36.1 (19.1, 330.9) by LJ, MGIT and LJ or MGIT respectively. Among HIV infected smear negative PTB suspects in Kampala, 93% of PTB cases are diagnosed upon the second serial sputum culture. The number of cultures needed to diagnose an additional PTB case, ranges from 11-30 and 35-56 by the second and third sputum samples, respectively.

    Children with complicated intrathoracic tuberculosis (TB) require rapid confirmation of TB diagnosis and of drug susceptibility to institute appropriate therapy. In a pilot study, we evaluated the feasibility and potential utility of GeneXpert (Xpert) on bronchoalveolar lavage (BAL) samples in children undergoing routine diagnostic bronchoscopy. We included children Children's Hospital, October 1, 2012-May 15, 2013. A minimum of two respiratory specimens in addition to BAL were obtained from each child. In addition to fluorescent smear microscopy and automated liquid culture performed on all samples, BAL samples were analyzed by Xpert. Drug susceptibility was confirmed by GenoType(®) MTBDRplus. Fourteen children (2 HIV positive, median age 16 months) were included. The Mantoux tuberculin skin test was positive in 11. On chest radiograph, six children had expansile pneumonia and nine had airway compression (one had both). The median duration of TB treatment before bronchoscopy was 8 days. TB was confirmed by either culture or Xpert from any sample in 11 (78%) children. Among 9/14 (64%) cases confirmed by culture, BAL Xpert was positive in 7 (78% sensitivity); in addition, Xpert confirmed 2 cases who had negative culture (14% additional diagnostic yield). Two drug resistant cases were identified: one by BAL Xpert and one from genotypic testing of a culture from gastric aspirate. All children were initiated on anti-TB treatment and responded well to therapy. BAL Xpert resulted in additional diagnostic yield and also in the rapid detection of drug resistance in children with complicated intrathoracic TB. The clinical impact of this modality should be further evaluated in children. © 2013 Wiley Periodicals, Inc.

    Full Text Available Context : Clinical, endoscopic, radiological and histological parameters of intestinal tuberculosis (IT and Crohn′s disease (CD are so similar that differentiation between these two diseases, which require different treatment, is difficult. Anti- Saccharomyces cerevisiae antibody (ASCA, which is often present in the sera of patients with CD, may be potentially useful to differentiate CD from IT. Aim : To evaluate the role of enzyme-linked immunosorbent assay test for ASCA in serum in differentiating CD from intestinal tuberculosis. Settings and Design : Prospective case-control study. Materials and Methods: Sixteen patients with IT, 16 CD, 36 UC diagnosed using standard parameters and 12 controls (11 healthy subjects and one with colonic carcinoma were tested for IgG ASCA in serum. Statistical Analysis Used : Categorical variables were analyzed using Chi-square test with Yates′ correction, as applicable. Continuous variables were analyzed using Mann-Whitney U test. Results : Eight of 16 (50% patients with IT, 10 of 16 with CD (62%, nine of 35 with UC (26% and one of 12 controls tested positive for ASCA in serum. Though the frequency of ASCA in serum was comparable among patients with IT and CD (8/16 vs. 10/16, P = ns, IT and UC (8/16 vs. 9/35, P =ns, CD and UC (10/16 vs. 9/35, P =ns, its frequency in CD or IT but not in UC was higher than healthy controls ( P < 0.01.

    Intestinal tuberculosis (ITB) and Crohn's disease (CD) are important differential diagnoses that can be difficult to distinguish. Polymerase chain reaction (PCR) for Mycobacterium tuberculosis (MTB) is an efficient and promising tool. This meta-analysis was performed to systematically and objectively assess the potential diagnostic accuracy and clinical value of PCR for MTB in distinguishing ITB from CD. We searched PubMed, Embase, Web of Science, Science Direct, and the Cochrane Library for eligible studies, and nine articles with 12 groups of data were identified. The included studies were subjected to quality assessment using the revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. The summary estimates were as follows: sensitivity 0.47 (95% CI: 0.42-0.51); specificity 0.95 (95% CI: 0.93-0.97); the positive likelihood ratio (PLR) 10.68 (95% CI: 6.98-16.35); the negative likelihood ratio (NLR) 0.49 (95% CI: 0.33-0.71); and diagnostic odds ratio (DOR) 21.92 (95% CI: 13.17-36.48). The area under the curve (AUC) was 0.9311, with a Q* value of 0.8664. Heterogeneity was found in the NLR. The heterogeneity of the studies was evaluated by meta-regression analysis and subgroup analysis. The current evidence suggests that PCR for MTB is a promising and highly specific diagnostic method to distinguish ITB from CD. However, physicians should also keep in mind that negative results cannot exclude ITB for its low sensitivity. Additional prospective studies are needed to further evaluate the diagnostic accuracy of PCR.

We found that the sanitary structure was inadequate, with latrines being shared with other rooms within the same accommodation; well water was the main source of water, and 48% of families had low incomes. The average rate of TB was 105/100, 000 inhabitants per year; one third of TB patients had been household contacts of infected individuals in the past, and 23% of rCts were LTBI. More than half (65%) of 44% of the stools examined (representing 76% of the housing) had IPIs; the highest prevalence was of fecal-oral transmitted protozoa (40%, Giardia intestinalis ), followed by soil-transmitted helminths (23%). TB transmission may be related to insufficient disease control of rCts, frequent relocation, and underreporting. Education, adopting hygienic habits, improving sanitation, provision of a treated water supply and efficient sewage system, further comprehensive epidemiological surveillance of those who enter and leave the community and resources for basic treatment of IPIs are crucial in combating the transmission of these neglected diseases.

    Full Text Available Abstract Background Previous health economic studies recommend either a dual screening strategy [tuberculin skin test (TST followed by interferon-γ-release assay (IGRA] or a single one [IGRA only] for latent tuberculosis infection (LTBI, the former largely based on claims that it is more cost-effective. We sought to examine that conclusion through the use of a model that accounts for the additional costs of adverse drug reactions and directly compares two commercially available versions of the IGRA: the Quantiferon-TB-Gold-In-Tube (QFT-GIT and T-SPOT.TB. Methods A LTBI screening model directed at screening contacts was used to perform a cost-effectiveness analysis, from a UK healthcare perspective, taking into account the risk of isoniazid-related hepatotoxicity and post-exposure TB (2 years post contact using the TST, QFT-GIT and T-SPOT.TB IGRAs. Results Examining costs alone, the TST/IGRA dual screening strategies (TST/T-SPOT.TB and TST/QFT-GIT; £162,387 and £157,048 per 1000 contacts, respectively cost less than their single strategy counterparts (T-SPOT.TB and QFT-GIT; £203,983 and £202,921 per 1000 contacts which have higher IGRA test costs and greater numbers of persons undergoing LTBI treatment. However, IGRA alone strategies direct healthcare interventions and costs more accurately to those that are truly infected. Subsequently, less contacts need to be treated to prevent an active case of TB (T-SPOT.TB and QFT-GIT; 61.7 and 69.7 contacts in IGRA alone strategies. IGRA single strategies also prevent more cases of post-exposure TB. However, this greater effectiveness does not outweigh the lower incremental costs associated with the dual strategies. Consequently, when these costs are combined with effectiveness, the IGRA dual strategies are more cost-effective than their single strategy counterparts. Comparing between the IGRAs, T-SPOT.TB-based strategies (single and dual; £39,712 and £37,206 per active TB case prevented

    Definitive and rapid diagnosis of extrapulmonary tuberculosis (EPTB) is challenging since conventional techniques have limitations due to the paucibacillary nature of the disease. To increase the sensitivity of detection of Mycobacterium tuberculosis (MTB) in EPTB specimens, we performed a nested PCR assay targeting several genes of MTB on EPTB specimens. A total of 100 clinical specimens from suspected cases of EPTB were processed. Standard staining for acid fast bacilli (AFB) was performed as the preliminary screening test. Extracted DNAs from specimens were subjected to Nested PCR technique for the detection of five different MTB target genes of IS6110, IS1081, hsp65kd, mbp64 , and mtp40 . On performing AFB staining, only 13% of specimens were positive, of which ascites fluid (33.3%), followed by pleural effusion (30.8%) showed the greatest AFB positivity rate. We demonstrated slight improvement in yields in lymph node which comprised the majority of specimens in this study, by employing PCR targeted to IS6110 - and hsp65-genes in comparison to AFB staining. However, the yields in ascites fluid and pleural effusion were not substantially improved by PCR, but those from bone and wound were, as in nested PCR employing either gene, the same positivity rate were obtained for ascites fluid (33.3%), while for pleural effusion specimens only IS1081 based PCR showed identical positivity rate with AFB stain (30.8%). The results for bone and wound specimens, however, demonstrated an improved yield mainly by employing IS1081 gene. Here, we report higher detection rate of EPTB in clinical specimens using five different targeted MTB genes. This nested PCR approach facilitates the comparison and the selection of the most frequently detected genes. Of course this study demonstrated the priority of IS1081 followed by mtp40 and IS6110 , among the five tested genes and indicates the effectiveness of any of the three genes in the design of an efficient nested-PCR test that

    Nuclear medicine plays an important role in the evaluation of infection and inflammation. A variety of diagnostic methods are available for imaging this inflammation and infection, most notably computed tomography, 68 Ga scintigraphy or radionuclide labeled leucocytes. Fluorine 18 fluorodeoxyglucose ( 18 F-F.D.G.) is a readily available radiotracer that offers rapid, exquisitely sensitive high-resolution images by positron emission tomography (PET). Inflammation can be acute or chronic, the former showing predominantly neutrophilic granulocyte infiltrates, whereas in the latter, macrophages predominate. F.D.G. uptake in infection is based on the fact that mononuclear cells and granulocytes use large quantities of glucose by way of the hexose monophosphate shunts. 18 F-F.D.G. PET accurately helps diagnose spinal osteomyelitis, diabetic foot and in inflammatory conditions such as sarcoidosis and tuberculosis.(it appears to be useful for defining the extent of disease and monitoring response to treatment). 18 F-F.D.G. PET can also help localize the source of fever of undetermined origin, thereby guiding additional testing. 18 F-F.D.G. PET may be of limited usefulness in postoperative patients and in patients with a failed joint prosthesis or bowel inflammatory disease. In this review, we will focus on the role of 18 F-F.D.G. PET in the management of patients with inflammation or suspected or confirmed infection

    Diagnosis of childhood tuberculosis is limited by the paucibacillary respiratory samples obtained from young children with pulmonary disease. We aimed to compare accuracy of the Xpert® MTB/RIF assay, an automated nucleic acid amplification test, between induced sputum and gastric lavage samples from young children in a tuberculosis endemic setting. We analyzed standardized diagnostic data from HIV negative children younger than four years of age who were investigated for tuberculosis disease near Cape Town, South Africa [2009-2012]. Two paired, consecutive induced sputa and early morning gastric lavage samples were obtained from children with suspected tuberculosis. Samples underwent Mycobacterial Growth Indicator Tube [MGIT] culture and Xpert MTB/RIF assay. We compared diagnostic yield across samples using the two-sample test of proportions and McNemar's χ2 test; and Wilson's score method to calculate sensitivity and specificity. 1,020 children were evaluated for tuberculosis during 1,214 admission episodes. Not all children had 4 samples collected. 57 of 4,463[1.3%] and 26 of 4,606[0.6%] samples tested positive for Mycobacterium tuberculosis on MGIT culture and Xpert MTB/RIF assay respectively. 27 of 2,198[1.2%] and 40 of 2,183[1.8%] samples tested positive [on either Xpert MTB/RIF assay or MGIT culture] on induced sputum and gastric lavage samples, respectively. 19/1,028[1.8%] and 33/1,017[3.2%] admission episodes yielded a positive MGIT culture or Xpert MTB/RIF assay from induced sputum and gastric lavage, respectively. Sensitivity of Xpert MTB/RIF assay was 8/30[26.7%; 95% CI: 14.2-44.4] for two induced sputum samples and 7/31[22.6%; 11.4-39.8] [p = 0.711] for two gastric lavage samples. Corresponding specificity was 893/893[100%;99.6-100] and 885/890[99.4%;98.7-99.8] respectively [p = 0.025]. Sensitivity of Xpert MTB/RIF assay was low, compared to MGIT culture, but diagnostic performance of Xpert MTB/RIF did not differ sufficiently between induced sputum

    Isolated ileocecal involvement by tuberculosis in the absence of pulmonar disease is rare in Brasil, therefore causes a diagnostic dilemma as it mimics colonic malignancy and Crohn's disease. Between 1969 and 1989, eight patients with isolated hypertrophic ileocecal tuberculosis were treated by surgery in the Gastroenterology Surgery Department of the HSPE-FMO. The most common complaint among them was abdominal pain (100%) with associated symptoms of weight loss (62.5%); nausea, vomiting, fever and general weekness appeared in half of the patients. A right iliac fossa mass was present in seven (87.5% ) of them. The mean duration of symptoms was 14.7 month (range 5-36 months). In all eight patients chest x-rays were negative for tuberculosis. Barium contrast studies showed abnormalities in all cases, but these could not be distinguished from carcinoma. Colonoscopy was helpful in establishing the diagnosis of suboclusive lesions of the ileocecal regions in three patients. Tuberculosis diagnosis was suspected in two of them because ofr the presence of granulomas in colonic biopsy material. Six patients were submitted to elective right hemicolectomy. The two remaining with suspect of tuberculosis were operated with signals of intestinal occlusion, and underwent a limited ileocaecal resection. The positive diagnosis of intestinal tuberculosis was made in all the patients by identification of acid-fast bacilli and by the presence of caseating granulomas in intestinal or lymph node tissue on histological examination. The outcome in all of them was favorable. They received treatment with three antituberculosis drugs over a twelve month period. Hypertrophic ileocecal tuberculosis must still be considered in the differential diagnosis of abdominal pathology localized in the right lower quadrant.

    To overcome the undesirable side effects and reduce the cytotoxicity of isoniazid (INH) and rifampin (RMP) in the digestive tract, a poly(methacrylic acid) (PMAA) nanogel was developed as a carrier of INH and RMP. This PMAA/INH/RMP nanogel was prepared as a treatment for intestinal tuberculosis caused by multidrug-resistant Mycobacterium tuberculosis (MTB). The morphology, size, and in vitro release properties were evaluated in a simulated gastrointestinal medium, and long-term antibacterial performance, cytotoxicity, stability, and activity of this novel PMAA/INH/RMP nanogel against multidrug-resistant MTB in the intestine were investigated. Our results indicate that the PMAA/INH/RMP nanogel exhibited extended antibacterial activity by virtue of its long-term release of INH and RMP in the simulated gastrointestinal medium. Further, this PMAA/INH/RMP nanogel exhibited lower cytotoxicity than did INH or RMP alone, suggesting that this PMAA/INH/RMP nanogel could be a more useful dosage form than separate doses of INH and RMP for intestinal MTB. The novel aspects of this study include the cytotoxicity study and the three-phase release profile study, which might be useful for other researchers in this field. Crown Copyright © 2015.

    Tuberculosis is a world wide communicable disease caused by tubercle bacilli discovered by Robert Kock in 1882. In 1993 WHO declared TB as a global emergency due to its world wide resurgence. It can involve any organ of the body. Abdomen is the fourth commonest site of involvement in the extra pulmonary tuberculosis after the lymph-nodes, skeletal and Genito urinary variants. In the gastro intestinal tract tuberculosis can affect any part from the mouth to the anus but ileocaecal area is a favourite location. Duodenal involvement is uncommon and accounts for only 2.5% of tuberculous enteritis. Major pathogens are Mycobacterium Tuberculosis and bovis and the usual route of entry is by direct penetration of the intestinal mucosa by swallowed organisms. (author)

Sixty patients for whom differential diagnosis between ITB and CD was difficult were enrolled between January 2007 and January 2009. The INF-gamma-producing T-cell response to early secreted antigenic target 6 and culture filtrate protein 10 were measured by T-SPOT.TB blood test in vitro. We evaluated the usefulness of T-SPOT.TB blood test by comparing its results with the final diagnosis. Twenty and forty patients were revealed to be positive and negative in T-SPOT.TB blood test, respectively. Of the 20 patients found to be positive, 12 patients (60%) were finally diagnosed as ITB, 6 patients as CD, and 2 patients as Behcets enterocolitis. Of the 40 patients with negative results, 38 patients (95%) were diagnosed as CD; one as Behcets enterocolitis; one as nonspecific colitis; none as ITB. The sensitivity and specificity of T-SPOT.TB blood test for ITB were 100% and 83.3%, respectively. Positive and negative predictive values of T-SPOT.TB blood test for ITB were 60.0% and 100%, respectively. When differential diagnosis between ITB and CD is difficult, T-SPOT.TB blood test may be a helpful and rapid diagnostic tool to exclude ITB. Prospective large-scaled studies are required for further evaluation of the usefulness of T-SPOT.TB blood test for differential diagnosis between ITB and CD.

    Full Text Available Paracoccidioidomycosis (PCM is an important systemic mycosis in LatinAmerica that occurs as active disease in 1-2% of Paracoccidioides brasiliensis infected people. Like PCM, tuberculosis (TB affects mainly the lungs and the clinical and radiological aspects do notalways allow differentiation between them. The aim of this study was to carry out serological investigation for detecting anti-P. brasiliensis antibodies, by three serological methods, in patientswith symptoms suggestive of pulmonary TB. From August 2005 to September 2006, 76 patients with pulmonary symptoms suspected for TB were attended at the Regional Specialties Center Laboratory in the city of Paranavaí, Paraná, Brazil and submitted to microbiological TB research, ELISA, immunodiffusion and immunoblotting for PCM. Of all the individuals, 21 (27.63% were reactive to P. brasiliensis by ELISA and 11 (14.47% showed a laboratory diagnosis of pulmonary TB. Of all the individuals serologically reactive to P. brasiliensis, by ELISA, none had positive results by immunodiffusion and one reacted with antigen 43 kDa when Immunobloting was carried out. Our results lead us to reflect a necessity to obtain a more specific serologic test for diagnosis of PCM disease in patients with respiratory symptoms considering the high number of individuals reactive to P. brasiliensis especially in endemic areas.Paracoccidioidomicose (PCM é importante micose sistêmica na América Latina, que ocorre como doença ativa em 1-2% dos indivíduos infectados com Paracoccidioides brasiliensis.

  19. Undiagnosed tuberculosis as clinical, epidemiological and medicolegal problem: Report of two cases

    2006-01-01

    Full Text Available The authors present two cases of undiagnosed tuberculosis in order to point out clinical, epidemiological and medicolegal importance of such cases. The first patient was a 29- year old woman, who died after 10-day hospital treatment, but true nature of her disease remained undiscovered. Due to her known marital problems, as well as numerous bruises developed as a consequence of hemorrhagic syndrome, violent death caused by injuries inflicted by her husband was suspected. Medicolegal autopsy and microscopic examination revealed fatal tuberculosis of the lungs, and small and large intestines. In another case, a 35-year old male died suddenly and unexpectedly, being found dead in his flat where numerous blood traces were noticed during the scene investigation. Therefore, possible homicide was suspected. Medicolegal investigation proved pulmonary tuberculosis as a cause of natural death. Presented cases point out the fact that even nowadays both pulmonary and extrapulmonary tuberculosis may remain clinically undiscovered, even when this disease is a cause of death. Hence, physicians should always keep in mind possible tuberculosis, especially in patients with long-lasting typical symptoms and signs. In both reported cases, the individuals suffered from cavernous pulmonary tuberculosis being thus a permanent source of infection. From medicolegal point of view, described cases represent examples of so called suspicious natural death. On the other hand, the fact that fatal tuberculosis remained clinically undiagnosed may make physicians be accused of medical negligence and malpractice.

    We report on a patient diagnosed with disseminated (hepatic and pulmonary) tuberculosis in the context of immunosuppression following liver transplant. During the administration of anti-tuberculosis drugs an abrupt elevation of liver enzymes was detected leading us to suspect drug toxicity rather than graft rejection. Nevertheless, careful surveillance and adjustment of serum levels of immunosuppressant drugs permitted continuance of tuberculosis treatment with no further side effects.

    Perinatal tuberculosis is acquired during birth or during the early neonatal period. Although its incidence is unknown, a search was conducted in Medline and 28 cases were found of perinatal tuberculosis reported from 1983 to 2011. Diagnosis of this disease is important due to having nonspecific symptoms that are mistaken for other infectious diseases. The disease has a high mortality rate (60%); therefore, it requires prompt diagnostic suspicion by the medical staff to prevent a fatal outcome. We describe the case of a 3-month-old male whose 29-year-old mother died of septic shock at 15 days of delivery. The infant's condition began within 30 days of age with cough and difficulty breathing with a diagnosis of multiple foci pneumonia. The infant presented respiratory impairment, meriting change of antibiotics twice, without improvement. The autopsy report of the mother revealed peritoneal tuberculosis. PCR was carried out using tracheal aspirate and pleural fluid of the patient, which were positive for Mycobacterium tuberculosis. Perinatal diagnosis of tuberculosis was established. No hepatic granuloma was found. Perinatal infection should be suspected in children with sepsis and/or pneumonia unresponsive to antibiotics. In this care, the history of tuberculosis in the mother should have oriented the diagnosis. Copyright © 2014 Hospital Infantil de México Federico Gómez. Publicado por Masson Doyma México S.A.

    Distinguishing between Crohn's Disease (CD) and Intestinal Tuberculosis (ITB) has been a challenging task for clinicians due to their similar presentation. CD4+FOXP3+ T regulatory cells (Tregs) have been reported to be increased in patients with pulmonary tuberculosis. However, there is no such data available in ITB. The aim of this study was to investigate the differential expression of FOXP3+ T cells in patients with ITB and CD and its utility as a biomarker. The study prospectively recruited 124 patients with CD, ITB and controls: ulcerative colitis (UC) and patients with only haemorrhoidal bleed. Frequency of CD4+CD25+FOXP3+ Tregs in peripheral blood (flow cytometry), FOXP3 mRNA expression in blood and colonic mucosa (qPCR) and FOXP3+ T cells in colonic mucosa (immunohistochemistry) were compared between controls, CD and ITB patients. Frequency of CD4+CD25+FOXP3+ Treg cells in peripheral blood was significantly increased in ITB as compared to CD. Similarly, significant increase in FOXP3+ T cells and FOXP3 mRNA expression was observed in colonic mucosa of ITB as compared to CD. ROC curve showed that a value of >32.5% for FOXP3+ cells in peripheral blood could differentiate between CD and ITB with a sensitivity of 75% and a specificity of 90.6%. Phenotypic enumeration of peripheral CD4+CD25+FOXP3+ Treg cells can be used as a non-invasive biomarker in clinics with a high diagnostic accuracy to differentiate between ITB and CD in regions where TB is endemic.

    in male. Intestinal obstruction is one of the commonest presentation of gastrointestinal tuberculosis presenting as surgical emergency and contributes significantly to high morbidity and mortality. Morbidity and mortality is less in the study due to early intervention and effective chemotherapy. CONCLUSION A high index of suspicion, proper evaluation and therapeutic trial in suspected patients is essential for an early diagnosis and timely definitive treatment, in order to decrease the morbidity and mortality associated with this disease.

    The use of liquid medium (MGIT960) for tuberculosis (TB) diagnosis was recommended by WHO in 2007. However, there has been no evaluation of its effectiveness on clinically important outcomes. A pragmatic trial was carried out in a tertiary hospital and a secondary health care unit in Rio de Janeiro City, Brazil. Participants were 16 years or older, suspected of having TB. They were excluded if only cerebral spinal fluid or blood specimens were available for analysis. MGIT960 technique was compared with the Lowenstein-Jensen (LJ) method for laboratory diagnosis of active TB. Primary outcome was the proportion of patients who had their initial medical management changed within 2 months after randomisation. Secondary outcomes were: mean time for changing the procedure, patient satisfaction with the overall treatment and adverse events. Data were analysed by intention-to-treat. Between April 2008 and September 2011, 693 patients were enrolled (348 to MGIT, 345 to LJ). Smear and culture results were positive for 10% and 15.7% of participants, respectively. Patients in the MGIT arm had their initial medical management changed more frequently than those in the LJ group (10.1% MGIT vs 3.8% LJ, RR 2.67 95% CI 1.44-.96, p = 0.002, NNT 16, 95% CI 10-39). Mean time for changing the initial procedure was greater in LJ group at both sites: 20.0 and 29.6 days in MGIT group and 52.2 and 64.3 in LJ group (MD 33.5, 95% CI 30.6-36.4, p = 0.0001). No other important differences were observed. This study suggests that opting for the MGIT960 system for TB diagnosis provides a promising case management model for improving the quality of care and control of TB.

    Tuberculosis (TB) is one of the oldest known diseases and has claimed more lives than any other Today, about one-third of the world's population is infected with TB. In 2003, 1,379 cases of new, active and relapsed TB were reported in Canada. TB is caused by Mycobacterium tuberculosis. Only 10 per cent of infected individuals will develop active TB. Pulmonary TB can be spread by an infectious person through the aerosolization of droplets when coughing, talking, spitting, sneezing or singing. Symptoms of pulmonary TB are a cough with or without sputum production lasting at least three weeks, chest pain, hemoptysis, fever, night sweats, weight loss, lack of appetite, chills and weakness. Extrapulmonary TB is generally not associated with person-to-person spread. Common sites include the throat, lymph nodes, abdomen, intestines, long bones of the legs, spine, kidneys, bladder, skin, eyes and meninges. The risk factors for TB infection and disease include close contact with an active pulmonary TB case, HIV infection or AIDS, inactive disease not adequately treated, low income, underlying medical condition, homelessness, alcoholism, injection drug use, aboriginal background or occupation in health care. Risk settings include travel or residence in an endemic area or work or residence in a correctional facility, shelter, rooming house, residential facility, hospital or long-term care facility. Nurses need to advocate for the prompt diagnosis and isolation of suspected and confirmed TB cases. Knowing when to institute such measures as isolation in a negative pressure room, using respirator masks and limiting interpersonal contacts is vital to the nursing care of TB patients. In addition, the role of the public health department needs to be understood; for example, all jurisdictions have legislated requirements for reporting new positive TB skin tests to public health.

    symptoms were collected. The presumptive diagnosis of pulmonary tuberculosis was made by summing up the scores of the data collected. The diagnosis of active tuberculosis was based on bacteriological findings and medical criteria. There were estimated sensitivity, specificity, positive predictive value and negative predictive value for a set prevalence, and 95% confidence intervals for different score cutoffs. The score performance was assessed using the receiver operating characteristic (ROC curve. RESULTS: For the diagnosis of tuberculosis, cough for more than one week and cough for more than three weeks showed a sensitivity of 88.2% (86.2, 90.2 and 61.1% (57.93, 64.3, specificity 19.2% (16.6, 21.8 and 51.3% (48.1, 54.5, respectively. The clinical score of 8 had a sensitivity of 83.13% (77.8, 87.6, specificity of 51.8% (48.5, 55.1, positive predictive value of 91.6% (90.0, 83.2 and negative predictive value of 32.9% (30.1, 35.7. CONCLUSIONS: Cough for more than three weeks showed low sensitivity and specificity. A highly sensitive clinical score can be an alternative tool for screening pulmonary tuberculosis as it allows early care of suspected cases and standard nursing care approach.

Participants interpreted 15 paediatric chest radiographs before and after a 30-minute course using three possible responses: (1) diagnostic for tuberculosis, (2) abnormal but inconclusive for diagnosis of tuberculosis and (3) normal. We compared proportions of correct diagnoses, sensitivity, and specificity, before and after the course. We included 256 participants comprising 229 non-radiologists (134 radiographers, 32 paediatricians, 39 Medecins Sans Frontieres clinicians and 24 physicians including paediatricians) and 27 radiologists. Mean change proportions of correct diagnosis ranged from -27% to 53% for individuals and 9% to 20% for groups. All groups showed a statistically significant improvement. Mean change in diagnostic sensitivity ranged from -38% to 100% for individuals and from 16% to 41% for groups. All groups showed a statistically significant improvement. Mean change in specificity ranged from -57% to 57% for individuals and from -15% to -4% for groups. The decrease was statistically significant for physicians, paediatricians and radiographers. The course resulted in increased correct diagnoses and improved sensitivity at the expense of specificity. (orig.)

    Intestinal tuberculosis is generally diagnosed using conventional barium studies, however recent diagnostic modalities such as ultrasonography and CT scan are widely applicated in conjunction with conventional studies for the search of lymph node presentation and associated extra-intestinal organs. It is important to differentiate intra-abdominal tuberculosis from metastatic or lymphomatous disease clinically. And it might be especially of worth to find out if there is any differential point between tuberculosis and other lymph nodal disease entities when we meet similar findings on imaging modalities. Authors have tried to evaluate ultrasonographic findings in conjunction with other studies in nine cases of abdominal tuberculosis which showed mainly extra-intestinal and/or lymph nodal involvement

    Effects of atomic bomb on tuberculosis among atomic bomb survivors necropsied after 1956 when Atomic Bomb Hospital was opened were observed statistically and the following results were obtained. The morbidity of tuberculosis in the group exposed within 2 km from the hypocenter was higher than that of the control group, but there was not a significant difference between the both groups. The morbidity of all types of tuberculosis was significantly higher in the group exposed within 2 km from the hypocenter than in the control group. The morbidity of tuberculosis tended to decrease in both exposed and non-exposed groups with time. However, the morbidity of miliary or active tuberculosis has tended to rise in the exposed since 1975. The morbidity in young a-bomb survivors exposed within 2 km was higher than that in those of other groups, but there was not a difference in the morbidity among the aged. The higher the rate of complication of active tuberculosis with stomach cancer or acute myelocytic leukemia or liver cirrhosis, the nearer the places of exposure were to the hypocenter. Out of 26 patients with miliary tuberculosis, 6 were suspected to have leukemia while they were alive and were suggested to have leukemoid reaction by autopsy. They all were a-bomb survivors, and 4 of them were exposed within 2 km from the hypocenter. (Tsunoda, M.)

    Background: Intestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The most frequent causes of intestinal obstruction are postoperative adhesions and hernias, which cause extrinsic compression of the intestine. Less frequently, tumours or strictures of the bowel can cause intrinsic blockage. Objective of the study was to find out the various a etiological factors of mechanical intestinal obstruction and to evaluate the morbidity and mortality in adult patients presenting to Surgical 'A' unit of Ayub teaching hospital with mechanical intestinal obstruction. Methods: This cross-sectional study was conducted from March 2009 to September, 2009. All patients presenting with intestinal obstruction and were above the age of 12 years were included in the study. Patients with non-mechanical obstruction were excluded from the study and those who responded to conservative measures were also excluded. Results: A total of 36 patients with age ranging from 12 to 80 years (Mean age 37.72+-19.74 years) and male to female ratio of 1.77:1, were treated for mechanical intestinal obstruction. The most common cause for mechanical intestinal obstruction was adhesions (36.1%). Intestinal tuberculosis was the second most common cause (19.4%), while hernias and sigmoid volvulus affected 13.9% patients each. Malignancies were found in 5.6% cases. Conclusion: Adhesions and Tuberculosis are the leading causes of mechanical intestinal obstruction in Pakistan. Although some patients can be treated conservatively, a substantial portion requires immediate surgical intervention. (author)

    Full Text Available This study was conducted to determine the effects of different levels of crude protein (CP supplements to the diet of early-weaned yaks on their growth performance, intestinal development, and immune response. Forty 3-month-old weaned yaks were selected and assigned to four dietary groups (Control, 17, 19 and 21% CP. Dietary CP supplements had a significant effect on average daily gain (ADG, crypt depth (CD (duodenum, jejunum and ileum, villous height (VH (duodenum, jejunum and ileum and CD/VH (jejunum and ileum. Average daily gain, CD (duodenum, jejunum and ileum and VH (ileum showed quadratic increases as the dietary CP increased, whereas CD/VH (jejunum and ileum ratios showed quadratic decreases. Blood urea nitrogen (BUN, glucose (GLU, immunoglobulin G (IgG, IgM, interleukin-1 (IL-1, IL-2, tumor necrosis factor (TNF-α, and interferon (IFN-γ concentrations increased significantly, whereas albumin (ALB, alanine aminotransferase (ALT and aspartate aminotransferase (AST decreased significantly with dietary CP supplements. Dietary CP supplements significantly increased the concentrations of IL-6, TNF-α, IFN-γ and the nuclear factor of activated T cell transcription factor (NFAT for gene expression. As the dietary CP supplements increased, IL-6, IFN-γ and NF-AT gene expression showed quadratic increases. These results showed that the appropriate dietary CP supplementation improved the growth performance and intestinal development of earlyweaned yaks and thus that the CP supplements were beneficial and enhanced the humoral immunity response of yaks.

    Aim: Whole-body gallium scan was performed to evaluate the usefulness of gallium scan for detecting extrapulmonary tuberculosis (TB) lesions. Methods: Thirty-seven patients with extrapulmonary TB were included in this study. Four patients were found to have two lesions. Totally, 41 lesions were identified, including 19 TB arthritis, 8 spinal TB, 5 TB meningitis, 3 TB lymphadenopathy, 2 TB pericarditis, 1 TB peritonitis, 1 intestinal TB, 1 skin TB and 1 renal TB. Results: Of the 41 extrapulmonary TB lesions, gallium scan detected 32 lesions with a sensitivity of 78%. All the patients with TB meningitis showed negative gallium scan. When the five cases of TB meningitis were excluded, the detection sensitivity of gallium scan increased to 88.9% (32/36). Conclusion: Our data revealed that gallium scan is a convenient and useful method for evaluating extrapulmonary TB lesions other than TB-meningitis. We suggest that gallium scan be included in the clinical routine for patients with suspected extrapulmonary TB. (orig.) [de

    Our objective was to evaluate the incidence of colorectal tuberculosis in our series and to study its radiological spectrum. A total of 684 cases of proven gastrointestinal tuberculosis with positive barium contrast findings seen over a period of more than one decade were evaluated. The study did not include cases where colon was involved in direct contiguity with ileo-caecal tuberculosis. Seventy-four patients (10.8%) had colorectal tuberculosis. Commonest site involved was transverse colon, closely followed by rectum and ascending colon. Radiological findings observed were in the form of strictures (54%), colitis (39%) and polypoid lesions (7%). Complications noted were in the form of perforations and fistulae in 18.9% of cases. Colorectal tuberculosis is a very common site for gastrointestinal tuberculosis. Typical findings of colorectal tuberculosis are strictures, signs of colitis and polypoid lesions. Common complications are perforation and fistulae. (orig.)

    Tuberculosis (TB) is a contagious disease which can cause death. The disease is caused by Mycobacterium Tuberculosis which generally affects lungs and other organs such as lymph gland, intestine, kidneys, uterus, bone, and brain. The spread of TB occurs through the bacteria-contaminated air which is inhaled into the lungs. The symptoms of the TB patients are cough, chest pain, shortness of breath, appetite lose, weight lose, fever, cold, and fatigue. World Health Organization (WHO) reported that Indonesia placed the second in term of the most TB cases after India which has 23 % cases while China is reported to have 10 % cases in global. TB has become one of the greatest death threats in global. One way to countermeasure TB disease is by administering vaccination. However, a medication is needed when one has already infected. The medication can generally take 6 months of time which consists of two phases, inpatient and outpatient. Mathematical models to analyze the spread of TB have been widely developed. One of them is the SEIR type model. In this model the population is divided into four groups, which are suspectible (S), exposed (S), infected (I), recovered (R). In fact, a TB patient needs to undergo medication with a period of time in order to recover. This article discusses a model of TB spread with considering the term of recovery (time delay). The model is developed in SIR type where the population is divided into three groups, suspectible (S), infected (I), and recovered (R). Here, the vaccine is given to the susceptible group and the time delay is considered in the group undergoing the medication.

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    Abdominal tuberculosis usually involves a combination of organs (hepatosplenic, intestinal and/or genitourinary), lymph nodes (peritoneal and mesenteric) and peritoneum, mesentery and omentum. It preferentially affects immuno compromised patients (diabetic, cirrhotic, HIV-positive individuals). We present four cases in which abdominal tuberculosis involved only peritoneum, mesentery and omentum, with no radiological evidence of retroperitoneal lymph node or hepatosplenic disease. Exclusively peritoneal involvement is rare and the radiologic findings are nonspecific as they are also observed in other more common disorders. Despite this fact, tuberculosis should be included in the differential diagnosis, especially in immunocompromised patients. (Author) 8 refs

    There is a lack of standardized approach and terminology to classify the diverse spectrum of manifestations in tuberculosis. It is important to recognize the different clinical and radiographic patterns to guide treatment. As a result of changing epidemiology, there is considerable overlap in the radiologic presentations of primary tuberculosis and post-primary tuberculosis. In this article we promote a standardized approach in clinical and radiographic classification for children suspected of having or diagnosed with childhood tuberculosis. We propose standardized terms to diminish confusion and miscommunication, which can affect management. In addition, we present pitfalls and limitations of imaging.

    2012-10-01

    Following 48 years of successful operation of the National Tuberculosis Control Program, Cuban health authorities have placed tuberculosis elimination on the agenda. To this end some tuberculosis control processes and their indicators need redesigned and new ones introduced, related to: number and proportion of suspected tuberculosis cases among vulnerable population groups; tuberculosis suspects with sputum microscopy and culture results useful for diagnosis (interpretable); and number of identified contacts of reported tuberculosis cases who were fully investigated. Such new indicators have been validated and successfully implemented in all provinces (2011-12) and are in the approval pipeline for generalized use in the National Tuberculosis Control Program. These indicators complement existing criteria for quality of case detection and support more comprehensive program performance assessment.

    2014-04-01

    Acute appendicitis is one of the most common acute surgical presentations. However investigation and management is sometimes confounded in a pregnant patient. Appendicitis in pregnancy is often managed jointly by both the surgical and obstetric teams, which can lead to discrepant pathways, which may be detrimental to the patient. This review sets out to identify the normal physiological changes of pregnancy that pose diagnostic and therapeutic difficulties to the clinician, assess the more common differential diagnoses and review the current evidence to assist achieving a swift diagnosis and appropriate treatment. A literature review of the investigation and management of suspected appendicitis in pregnancy was undertaken. Guidelines by the relevant surgical, obstetric and radiological societies were also reviewed. There remains no consensus on the best diagnostic pathway for appendicitis in pregnancy; which is unsurprising given that appendicitis in non-pregnant patients can yield diagnostic conundrums. However this review identifies a role for MRI scanning as a useful adjunct in these patients. The increasing role of laparoscopy in these patients is also becoming more apparent. Appendicitis in pregnancy remains a complex problem necessitating a close working relationship between various specialties to achieve the best outcome for mother and fetus.

    ABSTRACT Tuberculosis treatment remains a challenge due to the need to consider, when approaching it, the context of individual and collective health. In addition, social and economic issues have been shown to be variables that need to be considered when it comes to treatment effectiveness. We conducted a critical review of the national and international literature on the treatment of tuberculosis in recent years with the aims of presenting health care workers with recommendations based on the situation in Brazil and better informing decision-making regarding tuberculosis patients so as to minimize morbidity and interrupt disease transmission.

    The prevalence of tuberculosis infection and disease among homeless persons is high. Several recent outbreaks have been reported in shelters for the homeless. To address this problem, the Centers for Disease Control, Atlanta, convened a group of consultants who made the following recommendations: (1) Tuberculosis should be suspected and sputum samples should be collected from any homeless individual with a productive cough. (2) Diagnosed or suspected tuberculosis in a homeless individual should be immediately reported to the health department. (3) Therapy should be fully supervised by a responsible person, and an intensive multidrug, six-month regimen should be utilized whenever possible. (4) A contact investigation should be conducted around each infectious case, and preventive therapy should be prescribed for high-risk infected individuals. (5) Shelter staff should receive a tuberculin skin test when they start work and every six to 12 months thereafter. (6) Skin test reactors should be considered for preventive therapy according to current guidelines. (7) Installation of ultraviolet lights to reduce transmission should be considered in some situations.

    suspected of having pulmonary tuberculosis and to determine the impact that the acquisition of this knowledge has on the therapeutic approach. METHODS: We evaluated 106 patients suspected of having pulmonary tuberculosis and referred to the pulmonology department of a public hospital in the city of Teresina, Brazil. Morning sputum specimens were evaluated for the presence of mycobacteria by sputum smear microscopy and culture. We used PCR and restriction enzyme analysis of the hsp65 gene (PRA-hsp65 to identify the strains of mycobacteria isolated in culture. RESULTS: A total of 206 sputum samples were analyzed. Patient ages ranged from 15 to 87 years, and 67% were male. There was cough in 100% of the cases. The predominant radiographic pattern was moderate disease, observed in 70%. Smear positivity was 76%, and isolation in culture occurred in 91% of the cultures. Traditional tests identified nontuberculous mycobacteria (NTM in 9% of the isolates. The PRA-hsp65 method confirmed these data, showing seven band patterns that were able to identify the isolated species of NTM: Mycobacterium kansasii; M. abscessus 1; M. abscessus 2; M. smegmatis; M. flavescens 1; M. gordonae 5; and M. gordonae 7. All of the patients with NTM were over 60 years of age, and bronchiectasis was seen in 88% of the X-rays. There were two cases of reinfection, initially attributed to M. abscessus and M. kansasii. CONCLUSIONS: In immunocompetent patients, NTM can infect the lungs. It is important to identify the specific NTM in order to establish the correct diagnosis and choose the most appropriate therapeutic regimen. The PRA-hsp65 method is useful in identifying NTM species and can be implemented in molecular biology laboratories that do not specialize in the identification of mycobacteria.

    Tuberculosis is an infectious disease which has caused a large number of mortality in Indonesia. This disease is caused by Mycrobacterium tuberculosis. Besides affecting lung, this disease also affects other organs such as lymph gland, intestine, kidneys, uterus, bone, and brain. This article discusses the epidemic of tuberculosis through employing the SEIR model. Here, the population is divided into four compartments which are susceptible, exposed, infected and recovered. The susceptible population is further grouped into two which are vaccinated group and unvaccinated group. The behavior of the epidemic is investigated through analysing the equilibrium of the model. The result shows that administering vaccine to the susceptible population contributes to the reduction of the tuberculosis epidemic rate.

    Kienzl-Palma, D.; Prosch, H.

    2016-01-01

    Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis and transmission is via an airborne route by droplet infection. In the majority of cases patients have thoracic TB, which most frequently presents with hilar lymphadenopathy and pulmonary manifestation. Due to the rise in incidence of TB in central Europe to be expected over the coming years, it is essential to be acquainted with the radiological manifestations of pulmonary TB, particularly to be able to discriminate active from inactive TB. Due to the use of molecular techniques entailing DNA fingerprinting, the traditional classification of TB in primary and postprimary TB is being challenged. These genetic studies have revealed that variations in the clinical and radiographic appearance of TB are mainly affected by the immune status of the patients. Due to the low prevalence of TB in central Europe and the wide variation of radiological presentations, the diagnosis and therapy of TB is often delayed. In this article, the radiographic manifestations of thoracic TB are summarized and discussed. Together with the medical history and bacteriological tests, chest X-ray imaging and computed tomography (CT) play a major role not only in the detection of TB but also in the follow-up during and after therapy. Chest X-radiographs should be the primary diagnostic method in patients with suspected TB in screening as well as for diagnosis and therapy monitoring. The use of CT is more sensitive than chest radiographs and is frequently performed after chest radiographs to obtain detailed information about subtle parenchymal changes or lymph node manifestation. When active TB is suspected CT should be performed. Tree in bud, lobular consolidations, centrilobular nodules, cavities and ground-glass opacification are typical changes in active TB. (orig.) [de

    Tuberculosis (TB) in children is a common cause of morbidity. Diagnosis is difficult because of paucibacillary nature of illness and difficulty in obtaining appropriate samples. Children presenting with poor weight gain, fever with or without cough for more than two weeks or contact with an adult in family with pulmonary tuberculosis should be investigated for TB. In all suspected cases of tuberculosis initial investigations include radiograph of chest (CXR) and Mantoux test. If CXR is suggestive of TB, an ambulatory gastric aspirate and induced sputum for acid fast bacilli (AFB) smear may be carried out in two days. Children with AFB positive or abnormal CXR with positive Mantoux test should be started on Antitubercular therapy (ATT). Rest of the patients require more investigations and should be referred to a specialist. All children with newly diagnosed tuberculosis should be treated with 6 mo of ATT (two months with 4 drugs, followed by four months with 2 drugs). Children on ATT should be monitored for improvement in symptoms and weight gain along with side effects of medications. CXR should be done after completion of treatment.

    In this infographic, the genetics, phylogeny, physiology, and pathogenesis mechanisms of Mycobacterium tuberculosis are shown. Mycobacterium tuberculosis is the etiological agent of tuberculosis (TB), the leading cause of death due to a single infectious agent, claiming 1.7 million lives in 2016. Of the deaths attributable to TB in 2016, 22% occurred in people coinfected with HIV, and close to 5% of the 10.4 million incident cases of this disease were resistant to at least two of the first-line TB drugs. In this infographic, we describe the fundamental features of the genetics, phylogeny, and physiology of this member of the phylum Actinobacteria, which is associated increasingly with drug resistance mediated by mutations and rearrangements in its single, circular chromosome. We also highlight the key pathogenesis mechanisms employed by this slow-growing, facultative intracellular bacterium, which include avoidance of host cell clearance by arrest of the normal macrophage maturation process.

    1994-12-01

    A 37 year old woman with duodenal ulcer not responsive to medical treatment was operated. Antrectomy, truncal vagotomy and Bilroth II gastrojejunostomy were performed. The histopathology revealed epithelioid cell granulomas with multinucleated cells and central ceseation, in the gastric side of the pylorus and in three isolated lymph nodes. With Ziehl-Neelsen staining there were multiple acid-fast bacilli. There was no evidence or previous history, personal or familial, or tuberculosis in an other localization. Epidemiology, pathology, diagnosis, and treatment of gastric tuberculosis are discussed according to the literature.

    Dissemination of the tubercle bacillus is of three types: bronchogenic, hematogenous, and lymphangitic. Bronchogenic dissemination occurs when exudate from a cavity or small area of caseation drains into a bronchus and is aspirated into previously uninfected areas either on the same or on the opposite side. This type of spreading occurs frequently after bleeding and when there is a cavity emptying into a bronchus. Hematogenous dissemination leads to miliary tuberculosis and to extrapulmonary lesions throughout the body. Acute massive hematogenous spread causes miliary tuberculosis, while chronic spread in smaller amounts usually results in the chronic extrapulmonary foci. Lymphangitic dissemination is common in primary infection. It is responsible for involvement with subsequent enlargement of hilar and mediastinal nodes that is often seen in children and in young black adults. The reaction to M. tuberculosis depends on the presence or absence of immunity to tuberculoprotein. In individuals having no tissue hypersensitivity or immunity, primary tuberculosis results. In those with immunity produced by previous infection or BCG vaccination, the reactivation (reinfection) disease may develop

    The protein degradation machinery of Mycobacterium tuberculosis includes a proteasome and a ubiquitin-like protein (Pup). Proteasome accessory factor A (PafA) attaches Pup to proteins to target them for degradation by the proteasome. Free Pup is unstable and never observed in extracts of M. tuberculosis , an observation that led us to hypothesize that PafA may need alternative sources of Pup. Here, we show that PafA can move Pup from one proteasome substrate, inositol 1-phosphate synthetase (Ino1), to two different proteins, malonyl coenzyme A (CoA)-acyl carrier protein transacylase (FabD) and lonely guy (Log). This apparent "transpupylation" reaction required a previously unrecognized depupylase activity in PafA, and, surprisingly, this depupylase activity was much more efficient than the activity of the dedicated depupylase Dop (deamidase of Pup). Thus, PafA can potentially use both newly synthesized Pup and recycled Pup to doom proteins for degradation. IMPORTANCE Unlike eukaryotes, which contain hundreds of ubiquitin ligases, Pup-containing bacteria appear to have a single ligase to pupylate dozens if not hundreds of different proteins. The observation that PafA can depupylate and transpupylate in vitro offers new insight into how protein stability is regulated in proteasome-bearing bacteria. Importantly, PafA and the dedicated depupylase Dop are each required for the full virulence of Mycobacterium tuberculosis Thus, inhibition of both enzymes may be extremely attractive for the development of therapeutics against tuberculosis.

    Full Text Available Objective: To study the informative value of the detection of mycobacteria in blood with the cultural method in patients with suspected tuberculous sepsis and to determine the most significant clinical and laboratory criteria for testing. Materials and methods: The investigation to detect M.tuberculosis was fulfilled in 159 HIV-positive patients with suspected tuberculosis sepsis. Blood culture was completed with culture medium Myco/F Lytic Culture Vials and analyzer BACTEC 9050. Results: Mycobacteria were detected in blood of 19 patients (11,9% of all patients: in 18 patients the growth of М. tuberculosis complex was detected (25,3% of all patients with diagnosed tuberculosis and in 1 patient it was Mycobacterium avium complex (0,6% of all patients. It was shown, that the probability of M.tuberculosis detection was especially associated with the severity of the disease, immunosupression (less than 100 cells/mkl, hemoglobin quantity less than 90 g/l (levels were determined through the seeking for the most significant cutoffs. It was not proofed, that meningoencephalitis develops more often in patients with proven bacteremia. There were no evident differences in detection frequency of mycobacteria in sputum between patients with tuberculous sepsis and without it.

    Full Text Available Tuberculosis is in the top 10 causes of death worldwide, being one of the most deadly infectious diseases. It is estimated that one of three people from the entire earth population has a latent infection with M tuberculosis. This aerobic bacterium possesses the ability to persist in host tissues for years and to begin replication once immunity declines. The lungs are most frequent site of infection as the Mycobacterium tuberculosis is carried by aerosol droplets and is commonly transmitted by respiratory route. The second way of transmission is by contaminated food. Intestinal contamination coexists with pulmonary tuberculosis and only 10% represent primitive enteric diseases. The ileocecal region is involved most frequently. Even in this context isolated appendicular involvement remains rare. We report the case of appendicular tuberculosis in a 17-year-old woman with no evidence of other location of disease elsewhere in the body.

Hasta hace poco tiempo el médico en general, iniciaba la exploración de su paciente con un interrogatorio, una inspección, un tacto y una serología con una obsesión sifilítica. En la época actual el médico y en especial el oftalmólogo debe tener una obsesión tuberculosa en la investigación etiológica. Cuántas veces en una afección ocular que de una manera lenta pero progresiva produce profundas alteraciones oculares, lleva el sello soterrado de una tuberculosis? Cuántos enfermos de una constitución en apariencia envidiable hacen precisamente por un exceso de sus defensas una alergia tuberculosa? Tan traicionera como la sífilis es la tuberculosis. La sífilis quema sus etapas y estalla con una hemorragia cerebral, una locura, una parálisis general, una ataxia locomotriz progresiva, una goma o una meningitis sifilítica. La tuberculosis hace su presentación con una afección ocular, una goma, una granulia, una artritis, una osteítis, o una meningitis óptico-quiasmática. Siendo esto así, es necesario, en la mayoría de las afecciones oculares, tratar de identificarla por los medios de diagnóstico de que hoy disponemos.

  16. Contact investigation in households of patients with tuberculosis in Hanoi, Vietnam: a prospective cohort study.

    Directory of Open Access Journals (Sweden)

    Gregory James Fox

    Full Text Available SETTING: Existing tuberculosis control strategies in Vietnam are based on symptomatic patients attending health services for investigation. This approach has not resulted in substantial reductions in the prevalence of tuberculosis disease, despite the National Tuberculosis Program achieving high treatment completion rates. Alternative approaches are being considered. OBJECTIVE: To determine the feasibility and yield of contact investigation in households of patients with smear positive pulmonary tuberculosis among household members of tuberculosis patients in Hanoi, Vietnam. METHODS: Household contacts of patients with smear positive pulmonary tuberculosis were recruited at four urban and rural District Tuberculosis Units in Hanoi. Clinical and radiological screening was conducted at baseline, six months and 12 months. Sputum microscopy and culture was performed in contacts suspected of having tuberculosis. MIRU-VNTR molecular testing was used to compare the strains of patients and their contacts with disease. RESULTS: Among 545 household contacts of 212 patients, four were diagnosed with tuberculosis at baseline (prevalence 734 cases per 100,000 persons, 95% CI 17-1451 and one was diagnosed with tuberculosis during the subsequent 12 months after initial screening (incidence 180 cases per 100,000 person-years, 95% CI 44-131. Two of these cases were culture positive for M. tuberculosis and both had identical or near-identical MIRU-VNTR strain types. CONCLUSION: Household contacts of patients with potentially infectious forms of tuberculosis have a high prevalence of disease. Household contact investigation is feasible in Vietnam. Further research is required to investigate its effectiveness.

    Tuberculosis is a systemic disease that still affects many people. While pleural involvement is frequently observed in extrapulmonary tuberculosis, multiple skeletal system and articular involvements are quite rare. FDG PET imaging could be a promising diagnostic and treatment monitoring method, especially in complicated cases and if the other methods are inadequate. In this case study, we report a patient who was admitted with suspected malignancy and then diagnosed with tuberculosis pleuritis, lymphadenitis, spondylodiscitis, and sacroiliitis with specific symptoms; the response to anti-tuberculosis therapy was shown using FDG PET/CT.

    We analyze, in a retrospective review, the clinical presentation of tuberculosis among 226 pediatric patients admitted to the Hospital Infantil La Fe of Valencia (Spain) during the years 1986-1989. We observed the persistence of severe forms of tuberculosis, such as miliary tuberculosis and tuberculous meningitis. Also, cases of extra-pulmonary tuberculosis seldom encountered nowadays like bone and joint, intestinal and lymph node infection were recorded. In view of the current status of pediatric tuberculosis, new recommendations should be developed, because this infection could potentially be eradicated if adequate treatment and prophylactic guidelines are followed.

    The Mycobacterium tuberculosis phosphate-specific transport (Pst) system controls gene expression in response to phosphate availability by inhibiting the activation of the SenX3-RegX3 two-component system under phosphate-rich conditions, but the mechanism of communication between these systems is unknown. In Escherichia coli , inhibition of the two-component system PhoR-PhoB under phosphate-rich conditions requires both the Pst system and PhoU, a putative adaptor protein. E. coli PhoU is also involved in the formation of persisters, a subpopulation of phenotypically antibiotic-tolerant bacteria. M. tuberculosis encodes two PhoU orthologs, PhoY1 and PhoY2. We generated phoY single- and double-deletion mutants and examined the expression of RegX3-regulated genes by quantitative reverse transcription-PCR (qRT-PCR). Gene expression was increased only in the Δ phoY1 Δ phoY2 double mutant and could be restored to the wild-type level by complementation with either phoY1 or phoY2 or by deletion of regX3 These data suggest that the PhoY proteins function redundantly to inhibit SenX3-RegX3 activation. We analyzed the frequencies of antibiotic-tolerant persister variants in the phoY mutants using several antibiotic combinations. Persister frequency was decreased at least 40-fold in the Δ phoY1 Δ phoY2 mutant compared to the frequency in the wild type, and this phenotype was RegX3 dependent. A Δ pstA1 mutant lacking a Pst system transmembrane component exhibited a similar RegX3-dependent decrease in persister frequency. In aerosol-infected mice, the Δ phoY1 Δ phoY2 and Δ pstA1 mutants were more susceptible to treatment with rifampin but not isoniazid. Our data demonstrate that disrupting phosphate sensing mediated by the PhoY proteins and the Pst system enhances the susceptibility of M. tuberculosis to antibiotics both in vitro and during infection. IMPORTANCE Persister variants, subpopulations of bacteria that are phenotypically antibiotic tolerant, contribute to

    Duodenal tuberculosis is an uncommon disease. It may be either extrinsic or intrinsic or both. In the extrinsic type there can either be primary duodenal involvement or compression due to enlarged para duodenal lymph nodes. The clinical presentation can be dyspeptic or obstructive symptoms. The dyspeptic symptoms include epigastric pain, nausea, and occasional vomiting and obstructive symptoms include bilious vomiting frequently after meals, epigastric pain, and generalized abdominal pain. This report describes a young lady presenting with gastric outlet obstruction symptoms due to tuberculous adhesion involving the proximal duodenum. (author)

    Tuberculosis (TB) remains endemic in many parts of the developing world and is increasingly seen in the developed world due to migration. A total of 1.3 million people die annually from the disease. Spinal TB is the most common musculoskeletal manifestation, affecting about 1 to 2% of all cases of TB. The coexistence of HIV, which is endemic in some regions, adds to the burden and the complexity of management. This review discusses the epidemiology, clinical presentation, diagnosis, impact of HIV and both the medical and surgical options in the management of spinal TB.

    International Nuclear Information System (INIS)

    Kienzl-Palma, D.; Prosch, H.

    2016-01-01

    Besides the lungs, tuberculosis (TB) can affect any organ system. In most cases, extrathoracic TB occurs in immunosuppressed patients as part of a severe illness via hematogenous spread. Extrathoracic involvement most commonly involves abdominal organs, especially the urogenital tract and less commonly the central nervous system (CNS) and the musculoskeletal system. Most frequently, computed tomography (CT) is used for detecting extrathoracic TB manifestations, except for CNS and musculoskeletal manifestations, where contrast-enhanced magnetic resonance imaging (MRI) is the gold standard. Extrathoracic manifestations of TB may be indistinguishable from inflammatory or malignant causes. Due to unspecific symptoms the diagnosis is often delayed. This article summarizes and discusses the various radiological manifestations of extrathoracic manifestation of TB. Radiological modalities for screening extrathoracic TB are CT and MRI. Conventional X-radiographs do not play a role in the diagnosis of extrathoracic TB. The possibility of extrathoracic TB should be considered particularly in immunosuppressed patients, such as the homeless, alcoholics or drug addicts or in patients with an immigrant background from the endemic areas of TB. The most likely site of extrathoracic TB is the abdomen; however, infections of the CNS or musculoskeletal systems and multisystem infections can also occur. In patients with suspected extrathoracic TB, radiological modalities for screening are CT, especially for abdominal infections and lymphadenopathy and MRI with contrast media for the musculoskeletal system and the CNS.

    There is a critical need for improved diagnosis of tuberculosis in children, particularly in young children with intrathoracic disease as this represents the most common type of tuberculosis in children and the greatest diagnostic challenge. There is also a need for standardized clinical case definitions for the evaluation of diagnostics in prospective clinical research studies that include children in whom tuberculosis is suspected but not confirmed by culture of Mycobacterium tuberculosis. A panel representing a wide range of expertise and child tuberculosis research experience aimed to develop standardized clinical research case definitions for intrathoracic tuberculosis in children to enable harmonized evaluation of new tuberculosis diagnostic technologies in pediatric populations. Draft definitions and statements were proposed and circulated widely for feedback. An expert panel then considered each of the proposed definitions and statements relating to clinical definitions. Formal group consensus rules were established and consensus was reached for each statement. The definitions presented in this article are intended for use in clinical research to evaluate diagnostic assays and not for individual patient diagnosis or treatment decisions. A complementary article addresses methodological issues to consider for research of diagnostics in children with suspected tuberculosis. PMID:22448023

    Full Text Available We report a case of 23-year-old male patient with tuberculosis verrucous cutis on the foot for a duration of six months without responding to routine treatment. Tuberculosis is a common disease worldwide. Extrapulmonary tuberculosis contributes to 10% of cases. Cutaneous tuberculosis occupies a small spectrum of extrapulmonary tuberculosis. Tuberculosis verrucosa cutis is an exogenous infection occurring in a previously sensitized patient by direct inoculation of the organism. It occurs in sensitized patients with a moderate to high immune response. The diagnosis in our patient was confirmed by history, clinical examination, histopathological examination and the patient’s response to anti-tuberculous therapy.

    Aim: Whole-body gallium scan was performed to evaluate the usefulness of gallium scan for detecting extrapulmonary tuberculosis (TB) lesions. Methods: Thirty-seven patients with extrapulmonary TB were included in this study. Four patients were found to have two lesions. Totally, 41 lesions were identified, including 19 TB arthritis, 8 spinal TB, 5 TB meningitis, 3 TB lymphadenopathy, 2 TB pericarditis, 1 TB peritonitis, 1 intestinal TB, 1 skin TB and 1 renal TB. Results: Of the 41 extrapulmonary TB lesions, gallium scan detected 32 lesions with a sensitivity of 78%. All the patients with TB meningitis showed negative gallium scan. When the five cases of TB meningitis were excluded, the detection sensitivity of gallium scan increased to 88.9% (32/36). Conclusion: Our data revealed that gallium scan is a convenient and useful method for evaluating extrapulmonary TB lesions other than TB-meningitis. We suggest that gallium scan be included in the clinical routine for patients with suspected extrapulmonary TB. (orig.)

    We evaluated the value of CT-guided transthoracic core biopsy for the diagnosis of mycobacterial pulmonary nodules. The 30 subjects in this study had pulmonary nodules that had been either diagnosed histopathologically as tuberculosis or were suspected as tuberculosis based on a specimen obtained by CT-guided transthoracic core biopsy. The histopathological findings, the existence of acid-fast bacilli in the biopsy specimens, and the clinical course of the patients after the biopsy were reviewed retrospectively. Two of the three histological findings for tuberculosis that included epithelioid cells, multinucleated giant cells and caseous necrosis were observed in 21 of the nodules which were therefore diagnosed as histological tuberculosis. Six of these 21 nodules were positive for acid-fast bacilli, confirming the diagnosis of tuberculosis. Thirteen of the 21 nodules did not contain acid-fast bacilli but decreased in size in response to antituberculous treatment and were therefore diagnosed as clinical tuberculosis. Seven nodules with only caseous necrosis were diagnosed as suspected tuberculosis, with a final diagnosis of tuberculosis being made in 4 of the nodules and a diagnosis of old tuberculosis in 2 nodules. Two nodules with only multinucleated giant cells were diagnosed as suspected tuberculosis with 1 of these nodules being diagnosed finally as tuberculosis and the other nodule as a nonspecific granuloma. When any two of the three following histopathological findings - epithelioid cells, multinucleated giant cells or caseous necrosis - are observed in a specimen obtained by CT-guided transthoracic core biopsy, the diagnosis of tuberculosis can be established without the detection of acid-fast bacilli or Mycobacterium tuberculosis

    The aim of the study was to investigate if there is a possible relation between intestinal parasitosis and handedness in patients with suspected intestinal parasitosis. Hand preference was assessed on the Edinburgh Handedness Inventory. Stool samples were examined microscopically for the presence of parasite. In the present study right-handers had many more helminth infections and left-handers had many more protozoon infections. Lower rate of helminth infections in the present study, and higher asthma incidences in the left-handed population in literature, may be associated with different immune machinery in left-handed people than in right-handed ones.

Animals with no obstruction detected on ultrasound were excluded if they could not be monitored for 48 hours to confirm absence of obstruction. Sonographic diagnosis of small intestinal obstruction was based on identification of at least two findings suggestive of intestinal obstruction. Ninety-two patients suspected of having intestinal obstruction were included. Correct diagnosis of intestinal obstruction was made in 21 cases (23%), and in 68 (74%) this diagnosis was excluded. Interpretation of the images on prospective analysis had sensitivity, positive predictive, specificity and negative predictive values of 100%, 87.5%, 95.8% and 100%, respectively. Ultrasonography is an excellent method for investigation of animals with gastrointestinal disorders, and is particularly useful for excluding obstructive processes. © 2011 British Small Animal Veterinary Association.

    Over 1.5-2 million tuberculosis deaths occur annually. Medical professionals are faced with a lot of challenges in delivering good health-care with unassisted automation in hospitals where there are several patients who need the doctor's attention. To automate the pre-laboratory screening process against tuberculosis infection to aid diagnosis and make it fast and accessible to the public via the Internet. The expert system we have built is designed to also take care of people who do not have access to medical experts, but would want to check their medical status. A rule-based approach has been used, and unified modeling language and the client-server architecture technique were applied to model the system and to develop it as a web-based expert system for tuberculosis diagnosis. Algorithmic rules in the Tuberculosis-Diagnosis Expert System necessitate decision coverage where tuberculosis is either suspected or not suspected. The architecture consists of a rule base, knowledge base, and patient database. These units interact with the inference engine, which receives patient' data through the Internet via a user interface. We present the architecture of the Tuberculosis-Diagnosis Expert System and its implementation. We evaluated it for usability to determine the level of effectiveness, efficiency and user satisfaction. The result of the usability evaluation reveals that the system has a usability of 4.08 out of a scale of 5. This is an indication of a more-than-average system performance. Several existing expert systems have been developed for the purpose of supporting different medical diagnoses, but none is designed to translate tuberculosis patients' symptomatic data for online pre-laboratory screening. Our Tuberculosis-Diagnosis Expert System is an effective solution for the implementation of the needed web-based expert system diagnosis. © The Author(s) 2013.

  19. Primary health care staff's perceptions of childhood tuberculosis: a qualitative study from Tanzania

    2012-01-01

    Background Diagnosing tuberculosis in children remains a great challenge in developing countries. Health staff working in the front line of the health service delivery system has a major responsibility for timely identification and referral of suspected cases of childhood tuberculosis. This study explored primary health care staff's perception, challenges and needs pertaining to the identification of children with tuberculosis in Muheza district in Tanzania. Methods We conducted a qualitative study that included 13 semi-structured interviews and 3 focus group discussions with a total of 29 health staff purposively sampled from primary health care facilities. Analysis was performed in accordance with the principles of a phenomenological analysis. Results Primary health care staff perceived childhood tuberculosis to be uncommon in the society and tuberculosis was rarely considered as a likely differential diagnosis. Long duration and severe signs of disease together with known exposure to tuberculosis were decisive for the staff to suspect tuberculosis in children and refer them to hospital. None of the staff felt equipped to identify cases of childhood tuberculosis and they experienced lack of knowledge, applicable tools and guidelines as the main challenges. They expressed the need for more training, supervision and referral feedback to improving case identification. Conclusions Inadequate awareness of the burden of childhood tuberculosis, limited knowledge of the wide spectrum of clinical presentation and lack of clinical decision support strategies is detrimental to the health staff's central responsibility of suspecting and referring children with tuberculosis especially in the early disease stages. Activities to improve case identification should focus on skills required by primary health care staff to fulfil their responsibility and reflect primary health care level capacities and challenges.

    Full Text Available Purpose: Intestinal myiasis is a condition when the fly larvae inhabit the gastrointestinal tract and are passed out in faeces. This type of infestation results when eggs or larvae of the fly, deposited on food are inadvertently taken by man. They survive the unfavourable conditions within the gastrointestinal tract and produce disturbances, which may vary from mild to severe. The condition is not uncommon and is often misdiagnosed as pinworm infestation. Correct diagnosis by the clinical microbiologist is important to avoid unnecessary treatment. Materials and Methods: We had 7 cases of intestinal myiasis. In 2 cases the larvae were reared to adult fly in modified meat and sand medium (developed by Udgaonkar. This medium is simple and can be easily prepared in the laboratory. Results: Of the 7 larvae, 5 were Sarcophaga haemorrhoidalis, 1 Megaselia species and 1 was identified as Muscina stabulans. Conclusions: S. haemorrhoidalis was the commonest maggot involved. A high index of suspicion is required for clinical diagnosis when the patient complains of passing wriggling worms in faeces for a long period without any response to antihelminthics. The reason for long duration of illness and recurrence of infestation is baffling. The nearest to cure was colonic wash. We feel prevention is of utmost importance, which is to avoid eating food articles with easy access to flies.

    The aim of this study was to evaluate computed tomography enteroclysis (CTE) of the small intestinal tract. A total of 36 patients underwent CTE for further examination of small intestinal disease. The indications were obscure gastrointestinal bleeding (OGIB) (n=16), suspected Crohn's disease (n=7), suspected and diagnosed by exclusion a small intestinal tumor (n=5), and others (n=8). Regarding OGIB, positive findings were observed in nine patients: angiodysplasia (n=2), suspected ileac tumor (n=2), colon cancer (n=1), colon diverticulosis and diverticulitis (n=2), Crohn's disease (n=1), and enteritis (n=1). As for Crohn's disease, hyperplasia of the small intestinal wall was shown in six patents. Positive findings of a small intestinal tumor were observed in two patients. In the 'others' category, colon diverticulitis was found in three patients and isolated dissection of the superior mesenteric artery in one of four patients with abdominal pain. Primary carcinoid was identified in the pancreas in one patient, with liver carcinoid metastasis in the remaining four patients. CT enteroclysis is a noninvasive method and useful approach in the diagnosis of small intestinal diseases. (author)

    A photofluorographic mass survey of P-A chest had been done to the 13136 residents (male 6264, female 6872) in Jeonbug province, Korea for about 2 years from May 5, to Dec.19, 1978 and from Mar. 5, to Dec. 22, 1979. The results are as follows: 1. The prevalence rate of all active pulmonary tuberculosis is 5.3%. 2. The prevalence rate of male(8.8%) is 4.2 times higher than that of female (2.1%). 3. The prevalence rates of all old age groups above fifty years are higher than that of remainder under fifty years of age. Of these, 61-70 years old age group is highest in prevalence rate. 4. According to extent of active pulmonary tuberculosis, 77.5% is minimal, 15.4% is moderately advanced, and 7.1% is far advanced. Inactive pulmonary tuberculosis are 39 cases (0.3% to objective population). 5. In the incidence of the involved side, right side is about 2 times higher than the left, and involvement of both sides is increased in moderately and far advance pulmonary tuberculosis. In all pulmonary tuberculosis, one or both upper lung fields are most commonly involved. The incidences of cavity in moderately and far advanced pulmonary tuberculosis show no significant difference. 6. The incidences of other intrathoracic lesions are as follows: suspected hypertensive heart disease 2.4%, dextrocardia with situs inversus 0.04%, pleural calcification 0.4%, pleural thickening 0.2%, pleural effusion 0.1%, pneumonia 0.02%, bronchiectasis 0.1%, lung abscess 0.02%, C.O.P.D. 0.2%, suspected lung tumor 0.06%, pneumothorax 0.0076%, and suspected mediastinal tumor 0.02%

    Full Text Available Drug-resistant spinal tuberculosis (TB is an emerging health problem in both developing and developed countries. In this review article, we aim to define management protocols for suspicion, diagnosis, and treatment of such patients. Spinal TB is a deep-seated paucibacillary lesion, and the demonstration of acid-fast bacilli on Ziehl-Neelsen staining is possible only in 10%–30% of cases. Drug resistance is suspected in patients showing the failure of clinicoradiological improvement or appearance of a fresh lesion of osteoarticular TB while on anti tubercular therapy (ATT for a minimum period of 5 months. The conventional culture of Mycobacterium tuberculosis remains the gold standard for both bacteriological diagnosis and drug sensitivity testing (DST; however, the high turn around time of 2–6 weeks for detection with added 3 weeks for DST is a major limitation. To overcome this problem, rapid culture methods and molecular methods have been introduced. From a public health perspective, reducing the period between diagnosis and treatment initiation has direct benefits for both the patient and the community. For all patients of drug-resistant spinal TB, a complete Drug-O-Gram should be prepared which includes details of all drugs, their doses, and duration. Patients with confirmed multidrug-resistant TB strains should receive a regimen with at least five effective drugs, including pyrazinamide and one injectable. Patients with resistance to additional antitubercular drugs should receive individualized ATT as per their DST results.

    Sputum induction, bronchoalveolar lavage, or gastric aspiration are often needed to produce adequate diagnostic respiratory samples from people with HIV in whom tuberculosis is suspected. Since these procedures are rarely appropriate in less-developed countries, we compared the performances of a simple string test and the gold-standard sputum induction. 160 HIV-positive adults under investigation for tuberculosis, and 52 asymptomatic HIV-positive control patients underwent the string test followed by sputum induction. The string test detected tuberculosis in 14 patients in whom this disease was suspected; sputum induction detected only eight of them (McNemar's test, p=0·03). These preliminary data suggest that the string test is safe and effective for retrieval of useful clinical specimens for diagnosis of pulmonary tuberculosis, and is at least as sensitive as sputum induction.

    Full Text Available Malnutrition and tuberculosis are both problems of considerable magnitude in most of the underdeveloped regions of the world. These two problems tend to interact with each other. Tuberculosis mortality rates in different economic groups in a community tend to vary inversely with their economic levels. Similarly, nutritional status is significantly lower in patients with active tuberculosis compared with healthy controls. Malnutrition can lead to secondary immunodeficiency that increases the host′s susceptibility to infection. In patients with tuberculosis, it leads to reduction in appetite, nutrient malabsorption, micronutrient malabsorption, and altered metabolism leading to wasting. Both, protein-energy malnutrition and micronutrients deficiencies increase the risk of tuberculosis. It has been found that malnourished tuberculosis patients have delayed recovery and higher mortality rates than well-nourished patients. Nutritional status of patients improves during tuberculosis chemotherapy. High prevalence of human immunodeficiency (HIV infection in the underdeveloped countries further aggravates the problem of malnutrition and tuberculosis. Effect of malnutrition on childhood tuberculosis and tuberculin skin test are other important considerations. Nutritional supplementation may represent a novel approach for fast recovery in tuberculosis patients. In addition, raising nutritional status of population may prove to be an effective measure to control tuberculosis in underdeveloped areas of world.

  16. Intestinal perforation by an ingested foreign body

    Full Text Available Abstract Objective: To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods: This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results: None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases, increased density of mesenteric fat (in all four cases, identification of the foreign body passing through the intestinal wall (in three cases, and gas in the peritoneal cavity (in one case. Conclusion: In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

  3. Seronegative Intestinal Villous Atrophy: A Diagnostic Challenge

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Celiac disease is the most important cause of intestinal villous atrophy. Seronegative intestinal villous atrophy, including those that are nonresponsive to a gluten-free diet, is a diagnostic challenge. In these cases, before establishing the diagnosis of seronegative celiac disease, alternative etiologies of atrophic enteropathy should be considered. Recently, a new clinical entity responsible for seronegative villous atrophy was described—olmesartan-induced sprue-like enteropathy. Herein, we report two uncommon cases of atrophic enteropathy in patients with arterial hypertension under olmesartan, who presented with severe chronic diarrhea and significant involuntary weight loss. Further investigation revealed intestinal villous atrophy and intraepithelial lymphocytosis. Celiac disease and other causes of villous atrophy were ruled out. Drug-induced enteropathy was suspected and clinical improvement and histologic recovery were verified after olmesartan withdrawal. These cases highlight the importance for clinicians to maintain a high index of suspicion for olmesartan as a precipitant of sprue-like enteropathy.

We performed a retrospective analysis of consecutive children hospitalized with suspected pulmonary tuberculosis in Cape Town, South Africa, who were enrolled in a diagnostic study. Children were categorized as definite tuberculosis (culture positive), probable tuberculosis (chest radiograph consistent), possible tuberculosis (chest radiograph inconsistent), or not tuberculosis (improved without tuberculosis treatment). We applied the NIH diagnostic categories to the cohort and evaluated their performance specifically in children with definite tuberculosis and not tuberculosis. Four hundred sixty-four children (median age, 25.1 months [interquartile range, 13.5-61.5 months]) were included; 96 (20.7%) were HIV infected. Of these, 165 (35.6%) were definite tuberculosis, and 299 (64.4%) were not tuberculosis. If strict NIH symptom criteria were applied, 100 (21.6%) were unclassifiable including 21 (21.0%) with definite pulmonary tuberculosis, as they did not meet the NIH criteria due to short duration of symptoms; 71 (71%) had cough children, there was moderate agreement (κ = 0.48) with 100% agreement for definite tuberculosis and moderate agreement for not tuberculosis (220 [60.4%] vs 89 [24.5%]). Entry criteria for diagnostic studies should not be restrictive. Data from this analysis have informed revision of the NIH definitions. © The Author 2015.

    Rapid, reliable diagnosis of tuberculosis is essential to initiate correct treatment, avoid severe complications, and prevent transmission. Conventional microbiological methods may not be an option if samples are formalin-fixed and paraffin-embedded (FFPE) for histopathological examination....... With the demonstration of necrotizing granulomatous inflammation, tuberculosis becomes an important differential diagnosis, although it was not initially suspected. Following paraffin extraction, BDProbeTec ET strand displacement amplification for detection of Mycobacterium tuberculosis complex (MTC) was applied to 47...

    Intestinal leiomyositis is a suspected autoimmune disorder affecting the muscularis propria layer of the gastrointestinal tract and is a cause of chronic intestinal pseudo-obstruction in humans and animals. To characterize the clinical presentation, histopathologic features, and outcome of dogs with intestinal leiomyositis in an effort to optimize treatment and prognosis. Six client-owned dogs. Retrospective case series. Medical records were reviewed to describe signalment, clinicopathologic and imaging findings, histopathologic diagnoses, treatment, and outcome. All biopsy specimens were reviewed by a board-certified pathologist. Median age of dogs was 5.4 years (range, 15 months-9 years). Consistent clinical signs included vomiting (6/6), regurgitation (2/6), and small bowel diarrhea (3/6). Median duration of clinical signs before presentation was 13 days (range, 5-150 days). Diagnostic imaging showed marked gastric distension with dilated small intestines in 4/6 dogs. Full-thickness intestinal biopsies were obtained in all dogs by laparotomy. Histopathology of the stomach and intestines disclosed mononuclear inflammation, myofiber degeneration and necrosis, and fibrosis centered within the region of myofiber loss in the intestinal muscularis propria. All dogs received various combinations of immunomodulatory and prokinetic treatment, antimicrobial agents, antiemetics, and IV fluids, but none of the dogs showed a clinically relevant improvement with treatment. Median survival was 19 days after diagnosis (range, 3-270 days). Intestinal leiomyositis is a cause of intestinal pseudo-obstruction and must be diagnosed by full-thickness intestinal biopsy. This disease should be considered in dogs with acute and chronic vomiting, regurgitation, and small bowel diarrhea. Copyright © 2015 The Authors.

    Measuring tuberculosis transmission is exceedingly difficult, given the remarkable variability in the timing of clinical disease after Mycobacterium tuberculosis infection; incident disease can result from either a recent (ie, weeks to months) or a remote (ie, several years to decades) infection event. Although we cannot identify with certainty the timing and location of tuberculosis transmission for individuals, approaches for estimating the individual probability of recent transmission and for estimating the fraction of tuberculosis cases due to recent transmission in populations have been developed. Data used to estimate the probable burden of recent transmission include tuberculosis case notifications in young children and trends in tuberculin skin test and interferon γ-release assays. More recently, M. tuberculosis whole-genome sequencing has been used to estimate population levels of recent transmission, identify the distribution of specific strains within communities, and decipher chains of transmission among culture-positive tuberculosis cases. The factors that drive the transmission of tuberculosis in communities depend on the burden of prevalent tuberculosis; the ways in which individuals live, work, and interact (eg, congregate settings); and the capacity of healthcare and public health systems to identify and effectively treat individuals with infectious forms of tuberculosis. Here we provide an overview of these factors, describe tools for measurement of ongoing transmission, and highlight knowledge gaps that must be addressed. © The Author 2017.

The guidelines provide information about such topics as: precautions, inspection and testing, dispositioning identified items, installed inspection and reporting suspect/counterfeit materials. These guidelines apply to users who are developing procurement documents, product acceptance/verification methods, company procedures, work instructions, etc. The intent of these SM guidelines in relation to the Quality Assurance Program Description (QAPD) and implementing company Management Control Procedures is not to substitute or replace existing requirements, as defined in either the QAPD or company implementing instructions (Management Control Procedures). Instead, the guidelines are intended to provide a consolidated source of information addressing the issue of Suspect/Counterfeit materials. These guidelines provide an extensive suspect component listing and suspect indications listing. Users can quickly check their suspect items against the list of manufacturers products (i.e., type, LD. number, and nameplate information) by consulting either of these listings.

  13. The Phenomenology of Specialization of Criminal Suspects

    2013-01-01

    A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commit crimes of certain types, and, for instance, are more prone to specialize in crimes related to fraud. We also find evidence of temporal specialization of suspects. Older persons are more specialized than younger ones, and some crime types are preferentially committed by suspects of different ages. PMID:23691257

  14. Diagnostic system strengthening for drug resistant tuberculosis in Nigeria: impact and challenges

    2017-03-01

    Full Text Available Background: The increasing prevalence of drug-resistant tuberculosis and the threat of extensively-drug-resistant tuberculosis in HIV hotspots have made the detection and treatment of drug-resistant tuberculosis in the sub-Saharan Africa setting a global public health priority. Objective: We sought to examine the impact and challenges of tuberculosis diagnostic capacity development for the detection of drug-resistant tuberculosis and bio-surveillance using a modular biosafety level 3 (BSL-3 laboratory in Nigeria. Method: In 2010, the United States President’s Emergency Plan for AIDS Relief (PEPFAR programme, through the Institute of Human Virology at the University of Maryland in Baltimore, Maryland, United States, deployed a modular, BSL-3 laboratory to support the national tuberculosis programme in drug-resistant tuberculosis detection and bio-surveillance for effective tuberculosis prevention and control. Results: From 2010 until present, sputum samples from 11 606 suspected cases in 33 states were screened for drug-resistant tuberculosis. Of those, 1500 (12.9% had mono-resistant tuberculosis strains, and 459 (4.0% cases had multidrug-resistant tuberculosis. Over the lastfour years, 133 scientists were trained in a train-the-trainer programme on advanced tuberculosis culture, drug susceptibility testing, line-probe assays and Xpert® MTB/RIF, in addition to safety operations for biosafety facilities. Power instability, running cost and seasonal dust are notable challenges to optimal performance and scale up. Conclusion: Movable BSL-3 containment laboratories can be deployed to improve diagnostic capacity for drug-resistant tuberculosis and bio-surveillance in settings with limited resources.

    2014-01-01

    Full Text Available A broad spectrum of endocrine conditions has been reported among adult patients with tuberculosis in Africa. This review aims to describe the magnitude and pathogenesis of the following endocrinopathies among patients with tuberculosis in Africa: adrenal insufficiency, diabetes mellitus, disorders of calcium and vitamin D metabolism, thyroid dysfunction and hypogonadism. PubMed database and Google scholar were used to search for the relevant published English language studies and case reports relating to endocrine abnormalities and tuberculosis in Africa up to July 2013. The search terms used were endocrine dysfunction, endocrine abnormalities, adrenal insufficiency, diabetes mellitus, thyroid dysfunction, hypogonadism, disorders of calcium and vitamin D metabolism, tuberculosis, Africa. Reference lists of the identified articles were further used to identify other studies. Adrenal insufficiency, diabetes mellitus and calcium-vitamin D abnormalities were the most prevalent and frequently reported endocrine disorders among adult patients with tuberculosis in Africa. A meticulous endocrine evaluation among tuberculosis patients with suspected endocrine abnormalities should be encouraged in Africa and other high TB endemic regions. Treatment of these endocrine disorders has generally been shown to improve quality of life and reduce mortality.

    To present a retrospective analysis of clinical and endoscopic features of 4 cases of immunocompetent hosts with intestinal histoplasmosis (IH). Four immunocompetent adults were diagnosed with IH between October 2005 and March 2015 at West China Hospital of Sichuan University. Clinical and endoscopic characteristics were summarized and analyzed retrospectively. GMS (Gomori methenamine silver), PAS (periodic acid-Schiff) and Giemsa staining technique were used to confirm Histoplasma capsulatum(H. capsulatum). The symptoms, signs, endoscopic presentations, radiographic imaging, pathological stain results and follow-up are presented as tables and illustrations. The cases were male patients, ranging from 33 to 61 years old, and primarily presented with non-specific symptoms such as irregular fever, weight loss, abdominal pain and distention. Hepatosplenomegaly and lymphadenopathy were the most common signs. Endoscopic manifestations were localized or diffuse congestion, edema, ulcers, and polypoid nodules with central erosion involving the terminal ileum, ascending colon, transverse colon, descending colon, sigmoid colon and rectum, similar to intestinal tuberculosis, tumor, and inflammatory bowel disease. Numerous yeast-like pathogens testing positive for PAS and GMS stains but negative for Giemsa were detected in the cytoplasm of the histiocytes, which were highly suggestive of H. capsulatum. Immunocompetent individuals suffering from histoplasmosis are rarely reported. It is necessary that gastroenterologists and endoscopists consider histoplasmosis as a differential diagnosis, even in immunocompetent patients.

    Ocular tuberculosis is an extrapulmonary tuberculous condition and has variable manifestations. The purpose of this review is to describe the clinical manifestations of ocular tuberculosis affecting the anterior and posterior segments of the eye in both immunocompetent and immunocompromised patients. Review of literature using Pubmed database. Mycobacterium tuberculosis may lead to formation of conjunctival granuloma, nodular scleritis, and interstitial keratitis. Lacrimal gland and orbital caseating granulomas are rare but may occur. The intraocular structures are also a target of insult by M. tuberculosis and may cause anterior granulomatous uveitis, anterior and posterior synechiae, secondary glaucoma, and cataract. The bacillus may involve the ciliary body, resulting in the formation of a localized caseating granuloma. Posterior segment manifestations include vitritis, retinal vasculitis, optic neuritis, serpiginous-like choroiditis, choroidal tubercules, subretinal neovascularization, and, rarely, endophthalmitis. The recognition of clinical signs of ocular tuberculosis is of utmost importance as it can provide clinical pathway toward tailored investigations and decision making for initiating anti-tuberculosis therapy.

    2013-09-01

    Full Text Available OBJECTIVE: To analyze the association between clinical/epidemiological characteristics and outcomes of tuberculosis treatment in patients with concomitant tuberculosis and chronic kidney disease (CKD in Brazil. METHODS: We used the Brazilian Ministry of Health National Case Registry Database to identify patients with tuberculosis and CKD, treated between 2007 and 2011. The tuberculosis treatment outcomes were compared with epidemiological and clinical characteristics of the subjects using a hierarchical multinomial logistic regression model, in which cure was the reference outcome. RESULTS: The prevalence of CKD among patients with tuberculosis was 0.4% (95% CI: 0.37-0.42%. The sample comprised 1,077 subjects. The outcomes were cure, in 58%; treatment abandonment, in 7%; death from tuberculosis, in 13%; and death from other causes, in 22%. The characteristics that differentiated the ORs for treatment abandonment or death were age; alcoholism; AIDS; previous noncompliance with treatment; transfer to another facility; suspected tuberculosis on chest X-ray; positive results in the first smear microscopy; and indications for/use of directly observed treatment, short-course strategy. CONCLUSIONS: Our data indicate the importance of sociodemographic characteristics for the diagnosis of tuberculosis in patients with CKD and underscore the need for tuberculosis control strategies targeting patients with chronic noncommunicable diseases, such as CKD.

    Tuberculosis is a major health problem in many parts of the world. Delay in initiation of the treatment may result in prolonged infectious state, drug resistance, relapse and death. Objectives: To determine the factors responsible for not starting tuberculosis treatment among smear positive tuberculosis patients. Study type, settings and duration: This cross sectional study was done at Pakistan Medical Research Council TB Research Center, King Edward Medical University, Lahore, from fifth March 2010 to fifth December 2010. Patients and Methods: Fifty sputum smear positive patients of tuberculosis who did not register themselves in treatment register and presumably did not initiate anti tuberculosis treatment were contacted using telephone or traced by their home addresses. Once contact was established, they were inquired about the reasons for not starting tuberculosis treatment. Results: Of 50 patients 38(76%)belonged to the lower socio economic class and 12(24%) to the lower middle class. Fourteen patients (28%) were illiterate and 23(46%) had only 8 years of education. Of the 50 cases 41(82%) were taking treatment from traditional healers and 4% did not go back to the DOTS program. Physical condition of the patient, social, domestic and religious issues also played some role in default. Conclusions: Lack of health education and poverty were the main factors responsible for non compliance from treatment. Policy message: Sputum testing sites should have a paramedic who should educate the patients about the benefits of treatment and the dangers of default or partial treatment. (author)

    This report provides guidance in the clinical approach to the evaluation of suspected physical abuse in children. The medical assessment is outlined with respect to obtaining a history, physical examination, and appropriate ancillary testing. The role of the physician may encompass reporting suspected abuse; assessing the consistency of the explanation, the child's developmental capabilities, and the characteristics of the injury or injuries; and coordination with other professionals to provide immediate and long-term treatment and follow-up for victims. Accurate and timely diagnosis of children who are suspected victims of abuse can ensure appropriate evaluation, investigation, and outcomes for these children and their families.

    Rationale: Isolation of patients suspected for tuberculosis (TB) is usually guided by serial sputum smears. Many of patients initially isolated will turn out not to have TB, or will not be regarded as contagious. Current standards imply isolation for hours or days until contagiousness has been......-positive on the sample that produced the PCR-negative result. Conclusion: Though adequate sensitivity in diagnosing TB still requires serial samples for microbiological examination, the question of isolation can be determined by first-sample PCR in the majority of cases, when the test is negative.

    Endometriosis intestines due to its non-specific symptoms can pose diagnostic problems, a lack of or incorrect treatment worsens the quality of life, sometimes leading to serious complications. The differential diagnosis of abdominal pain, especially in patients of reproductive age should be taken disease into account. Often abdominal pain in young women are classified as a functional gastrointestinal disorder, and only carefully collected intelligence allows you to focus on the diagnosis of endometriosis, especially if the symptoms significantly impair quality of life. A woman 32 year old who was admitted to the department of gastroenterology because of increasing pain in the abdomen. Due to the deteriorating condition of the patient, the characteristics of mechanical obstruction on imaging studies was transferred to the surgical ward with suspected Crohn's disease. She was treated surgically. Histopathological examination found endometriosis. Endometriosis outside the sex system can lead to serious complications.

    Full Text Available Small intestinal anisakiasis is a rare disease that is very difficult to diagnose, and its initial diagnosis is often surgical. However, it is typically a benign disease that resolves with conservative treatment, and unnecessary surgery can be avoided if it is appropriately diagnosed. This case report is an example of small intestinal obstruction caused by anisakiasis that resolved with conservative treatment. A 63-year-old man admitted to our department with acute abdominal pain. A history of raw fish (sushi ingestion was recorded. Abdominal CT demonstrated small intestinal dilatation with wall thickening and contrast enhancement. Ascitic fluid was found on the liver surface and in the Douglas pouch. His IgE (RIST was elevated, and he tested positive for the anti-Anisakis antibodies IgG and IgA. Small intestinal obstruction by anisakiasis was highly suspected and conservative treatment was performed, ileus tube, fasting, and fluid replacement. Symptoms quickly resolved, and he was discharged on the seventh day of admission. Small intestinal anisakiasis is a relatively uncommon disease, the diagnosis of which may be difficult. Because it is a self-limiting disease that usually resolves in 1-2 weeks, a conservative approach is advisable to avoid unnecessary surgery.

    A 63-year-old female patient was admitted to the authors' hospital for further diagnostic work-up for suspected reactivation of a previously successfully treated lymph node tuberculosis, which had been diagnosed 1 year prior to the current admission. The clinical signs consisted of worsening of the patient's general condition, negacervical lymphadenopathy, night sweats, dyspnea, and superficial inflammation of the right mamma. A contrast-enhanced CT scan of the neck, thorax and abdomen revealed a generalized enlargement of the cervical, axillar, mediastinal and retroperitoneal lymph nodes, multiple intrapulmonary nodular lesions with a diameter of up to 6 mm, and a substantial right-sided pleural effusion. Under the assumption of reactivation of a lymph node tuberculosis, the patient was initially treated with an extended tuberculostatic therapy. Because of disease progression another lymph node biopsy was performed revealing Hodgkin's disease of mixed-cellularity type with a partly histiocytic necrotizing, partly tuberculoid reaction. The biopsy was negative for acid-fast bacilli. Thereupon initiated chemotherapy according to the ABVD protocol led to a rapid amelioration of the clinical symptoms. In the clinical setting of suspected or confirmed lymph node tuberculosis malignant lymphoma should always be considered. This consideration is particular important since Hodgkin's disease is typically associated with a cellular immunosuppression predisposing the subject to tuberculosis.

    The diagnosis and treatment of congenital tuberculosis are discussed. Congenital tuberculosis is rare and fatal if left untreated. If a pregnant woman with tuberculosis is not treated, infection of the fetus can occur by hematogenous spread through the umbilical cord or by aspiration or ingestion of amniotic fluid. Signs and symptoms of congenital tuberculosis may be nonspecific, which may preclude early diagnosis and treatment. Criteria for the diagnosis of congenital tuberculosis require the infant to have a tuberculous lesion, as indicated by chest radiography or granulomas, and at least one of the following should be confirmed: (1) onset during the first week of life, (2) primary hepatic tuberculosis complex or caseating hepatic granulomas, (3) infection of the placenta or maternal genital tract, or (4) exclusion of postnatal transmission by a contact investigation. Since 2001, 21 cases of congenital tuberculosis have been reported in English-language medical journals, with the age of presentation ranging from day 1 to 90. Based on findings from published case reports, congenital tuberculosis should be considered in the differential diagnosis of newborns who have (1) nonresponsive, worsening pneumonia, especially in regions with high rates of tuberculosis, (2) nonspecific symptoms but have a mother diagnosed with tuberculosis, (3) high lymphocyte counts in the cerebrospinal fluid without an identified bacterial pathogen, or (4) fever and hepatosplenomegaly. Once diagnosed, it is essential to promptly begin treatment with isoniazid, rifampin, pyrazinamide, and streptomycin in order to decrease the mortality associated with the infection. Early diagnosis and treatment during the neonatal period are crucial in minimizing the fatality associated with congenital tuberculosis.

    To evaluate the usefulness of CT for the diagnosis and treatment planning of mechanical intestinal obstruction. We retrospectively reviewed 38 patients who were clinically suspected of mechanical intestinal obstruction and had undergone abdominal CT. The CT scans were evaluated for the absence or presence, severity, cause and site of intestinal obstruction. CT findings were compared with the results of laparotomy, barium study and clinical course. The absence or presence and severity of intestinal obstruction were classified into no obstruction, partial obstruction, complete obstruction. Diagnosis was established by means of laparotomy in 20 cases, barium study in 9 cases and clinical course in 9 cases. Of 38 cases, 7(18.4%) showed no obstruction, 22(57.9%) showed partial obstruction, and 9(23.7%) showed complete obstruction. The presence or absence and severity on CT scans were correctly predicted in 36 of 38 cases (sensitivity 95 %, specificity 97 %, accuracy 96 %) (in case of no obstruction: sensitivity 100 %, specificity 94%, accuracy 95%; in case of partial obstruction : sensitivity 91%, specificity 100%, accuracy 95%; in case of complete obstruction : sensitivity 100%, specificity 100%, accuracy 100%). All 9 cases with complete obstruction underwent prompt and immediate laparotomy. 13 cases, excluding those with mass around the site of transition and adhesion with strangulation, with partial obstruction improved with conservative treatment without laparotomy. The causes of obstruction were adhesion in 13, hernia in 6, primary cancer in 5, metastatic cancer in 3, abscess in 2, intestinal tbc in 1, and Crohn's disease in 1. The cause of obstruction on CT scans were correctly predicted in 27 of 31 cases (87.1 %). The sites of obstruction on CT scans were correctly predicted in 22 of 26 cases (84.6%). CT is valuable in the evaluation of absence or presence, severity, cause and site of intestinal obstruction, and is considered to be helpful in treatment

    A paradoxical reaction (PR) during anti-tuberculosis treatment is a phenomenon that is poorly studied in immunocompetent children. It is defined as a clinical or radiological worsening of pre-existing tuberculosis (TB) disease. A retrospective descriptive study of children younger than 14 years of age was performed; these children developed PR during the years 2009 to 2014, following a diagnosis of TB. Demographic characteristics, microbiological results, treatment and outcome data were collected. Of 51 children diagnosed with TB, five (9.8%) developed a PR; four of these children had pulmonary TB and the remaining patient had miliary TB with central nervous system involvement. The PR occurred at a median of 42 days (range 23-53 days) after initiating therapy. Corticosteroids were started when PR was suspected, at a median dose of 1mg/kg/day. Clinical and radiological improvement was noted in all cases, with a median clinical regression time of 10.5 days (range 3-15 days) and a median radiological regression time of 45 days (range 26-105 days). No sequelae were described in any patient. PR in immunocompetent children during anti-tuberculosis treatment is not such an unusual reaction. Treatment with corticosteroids may be useful for the resolution of PR. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Multifocal tuberculosis is defined as the presence of lesions affecting at least two extrapulmonary sites, with or without pulmonary involvement. This retrospective study of 10 cases aims to investigate the clinical and evolutionary characteristics of multifocal tuberculosis. It included 41 cases with tuberculosis collected between 1999 and 2013. Ten patients had multifocal tuberculosis (24%): 9 women and 1 man, the average age was 50 years (30-68 years). Our patients were correctly BCG vaccinated. The evaluation of immunodepression was negative in all patients. 7 cases had lymph node tuberculosis, 3 cases digestive tuberculosis, 2 cases pericardial tuberculosis, 2 cases osteoarticular tuberculosis, 1 case brain tuberculosis, 2 cases urinary tuberculosis, 4 cases urogenital tuberculosis, 1 case adrenal tuberculosis, 1 case cutaneous and 1 case muscle tuberculosis. All patients received anti-tuberculosis treatment for a mean duration of 10 months, with good evolution. Multifocal tuberculosis is difficult to diagnose. It can affect immunocompetent patients but often has good prognosis. Anti-tuberculosis therapy must be initiated as soon as possible to avoid sequelae.

    Full Text Available Objectives: This study was designed to review previous studies and analyse the current knowledge and controversies related to seasonal variability of tuberculosis (TB to examine whether TB has an annual seasonal pattern. Study Design and Methods: Systematic review of peer reviewed studies identified through literature searches using online databases belonging to PubMed and the Cochrane library with key words "Tuberculosis, Seasonal influence" and " Tuberculosis, Seasonal variation". The search was restricted to articles published in English. The references of the identified papers for further relevant publications were also reviewed. Results: Twelve studies conducted between the period 1971 and 2006 from 11 countries/regions around the world (South Western Cameroon, South Africa, India, Hong Kong, Japan, Kuwait, Spain, UK, Ireland, Russia, and Mongolia were reviewed. A seasonal pattern of tuberculosis with a mostly predominant peak is seen during the spring and summer seasons in all of the countries (except South Western Cameroon and Russia. Conclusions: The observation of seasonality leads to assume that the risk of transmission of M. tuberculosis does appear to be the greatest during winter months. Vitamin D level variability, indoor activities, seasonal change in immune function, and delays in the diagnosis and treatment of tuberculosis are potential stimuli of seasonal tuberculosis disease. Additionally, seasonal variation in food availability and food intake, age, and sex are important factors which can play a role in the tuberculosis notification variability. Prospective studies regarding this topic and other related subjects are highly recommended.

In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis.

    Purpose and methods. To perform an illustrated and educational review of musculoskeletal tuberculosis. Results. As the incidence of musculoskeletal tuberculosis still increases, a review appears justified. The following four main presentations are detailed and illustrated, by emphasizing the value of both CT and MR imaging: a) spine tuberculosis (∼ 50 %/) commonly involves two adjacent vertebral bodies with usual large paravertebral abscesses. The following lesions are highly suggestive of tuberculosis: solitary vertebral involvement, solitary epidural abscess with or without erosive spondylitis; b) osteo-arthritis: peripherally located erosions at synovial insertions with gradual narrowing of the joint space are highly suggestive; c) osteomyelitis: unusual, may involve any bones; d) tenosynovitis and bursitis. Conclusion. Imaging studies are essential for diagnosis and to assess the extent of musculo-skeletal tuberculosis. (author)

    Tuberculosis screening of people living with HIV (PLHIV) can contribute to early tuberculosis diagnosis and improved patient outcomes. Evidence-based guidelines for tuberculosis screening are available, but literature assessing their implementation and the quality of clinical practice is scarce. To assess tuberculosis screening practices and the effectiveness of audit and performance feedback to improve quality of tuberculosis screening at HIV care clinics in Ghana. Healthcare providers at 10 large HIV care clinics prospectively registered patient consultations during May and October 2014, before and after a performance feedback intervention in August 2014. The outcomes of interest were overall tuberculosis suspicion rate during consultations and provider adherence to the International Standards for Tuberculosis Care and the World Health Organizations' guidelines for symptom-based tuberculosis screening among PLHIV. Twenty-one healthcare providers registered a total of 2,666 consultations; 1,368 consultations before and 1,298 consultations after the feedback intervention. Tuberculosis suspicion rate during consultation increased from 12.6 to 20.9% after feedback (odds ratio, OR 1.83; 95% confidence interval, CI: 1.09-3.09). Before feedback, sputum smear microscopy was requested for 58.7% of patients with suspected tuberculosis, for 47.2% of patients with cough ≥2 weeks, and for 27.5% of patients with a positive World Health Organization (WHO) symptom screen (any of current cough, fever, weight loss or night sweats). After feedback, patients with a positive WHO symptom screen were more likely to be suspected of tuberculosis (OR 2.21; 95% CI: 1.19-4.09) and referred for microscopy (OR 2.71; 95% CI: 1.25-5.86). A simple prospective audit tool identified flaws in clinical practices for tuberculosis screening of PLHIV. There was no systematic identification of people with suspected active tuberculosis. We found low initial tuberculosis suspicion rate compounded by low

    It was known that some of the abdominal tuberculosis can produce tumor-like appearance clinically and radiologically. But these were mainly masses formed in mesenteric and retroperitoneal lymph nodes. The author has experienced the gastrointestinal tuberculosis resembling to a neoplastic process. In the gastric tuberculosis, irregular narrowing and filling defect with mucosal distortion and occasional shoulder effect could be seen in pyloric antrum. Deformity of proximal portion of duodenum was noted in most cases. Difficulty in differential diagnosis from the gastric cancer might be encountered. If duodenum was not involved. No definite sign of mucosal destruction involved area and associated deformity of duodenum was suggestive of an inflammatory lesion. If there is any tuberculous changes in small bowel, than gastric tuberculosis is more likely. There was the tuberculosis of descending duodenum or pancreaticoduodenal group of lymph nodes revealed cancer-like appearance. Long irregular narrowing with nodular filling defect and mucosal distortion or inverted 3 sign was evident. Differential diagnosis from cancer in duodenum or pancreas could not be made radiographically. Short annular stenosis and nodular filling defect with shoulder effect in both ends of stenosis was noted in some of small bowel tuberculosis. The findings were very resemble to malignancy. There was a case of huge hepatoma-like tuberculosis formed a large irregular mass by lymph nodes and adjacent organs. Chest film was not much help in the differential diagnosis. In many cases of the gastrointestinal tuberculosis, radiological findings were resembled to a neoplastic process. Since none of radiologic findings are specific enough to allow one to make a definitive diagnosis of the gastrointestinal tuberculosis and since type of the gastrointestinal tuberculosis could be cured by chemotherapy, careful analyzation of clinical features is emphasized before surgery.

    During drug treatment of tuberculous lymphadenitis, paradoxical response (PR) may occasionally occur. Continued treatment or lymph node aspiration improves PR without severe sequelae. However, we report a case of severe PR in a patient with cervical lymph node tuberculosis causing airway obstruction due to retropharyngeal lymph node swelling during antituberculous treatment. Tracheostomy and drainage of the node were performed to secure the airway. Possible airway obstruction due to PR must be suspected when cervical lymph node tuberculosis involves the retropharyngeal lymph node.

    The use of radiopharmaceuticals in evaluation of pulmonary tuberculosis may help to resolve difficult diagnostic problems such as discordance between sputum examinations and chest roentgenographic findings. We investigated the usefulness of 99m Tc-methoxyisobutylisonitrile (MIBI) scintigraphy in the detection of active pulmonary tuberculosis. Forty-six patients with suspected active pulmonary tuberculosis were studied with sputum smear of AFB, sputum AFB culture, chest X-ray and MIBI scan. MIBI image was obtained 15 and 60 min after intravenous injection of 370MBq(10mCi) 99m Tc-MIBI. In 16 patients of them Ga scans were performed in addition to MIBI scan. Repeated MIBI scans were done in 7 patients with active pulmonary tuberculosis after 4∼6 months of antituberculous chemotherapy. Thirty-two patients were confirmed as active tuberculosis by sputum culture. Sensitivity of MIBI scan to active tuberculosis was 87.5%(28/32) and MIBI findings were negative in all of 14 patients with inactive disease. Focal uptake of MIBI was dense in the area that was strongly suggested active tuberculous lesions by chest roentgenogram. There was no discordance between MIBI and Ga image in 16 patients. But the uptake areas of Ga images were broader than that of MIBI images. After 4∼6 months of antituberculous treatment all repeated MIBI scans revealed negative findings except 1 patient with persistent active pulmonary tuberculosis due to drug resistance. MIBI scan could be used in the detection of active pulmonary tuberculosis as a useful noninvasive diagnostic tool

    Full Text Available Cutaneous tuberculosis forms a small proportion of extrapulmonary tuberculosis. The incidence of cutaneous tuberculosis has fallen from 2% to 0.15% in India whereas it is rare in developed countries. The present study is an attempt at finding out the Mycobacterium species associated with cutaneous tuberculosis. A total of 51 cases of clinically suspected cutaneous tuberculosis were studied over a period of 18 months from July 1997 to December 1998. Of these, 32 (62.75% were Scrofuloderma cases, 12 (23.52% cases of Lupus vulgaris and 7 (13.73% were Tuberculosis verrucosa cutis (TBVC cases. Twenty nine mycobacterial isolates from 51 specimens gave an isolation rate of 56.86%. These were subjected to a battery of biochemical tests for identification to species level. Twenty six out of 29 isolates were identified as Mycobacterium tuberculosis, two were identified as Mycobacterium Scrofulaceum and one Mycobacterium avium complex was isolated. Sixteen Mycobacterial isolates were recovered from Scrofuloderma cases, 9 were isolated from Lupus vulgaris and 4 from TBVC cases. The three atypical mycobacterial isolates were recovered from Scrofuloderma cases. Though Mycobacterium tuberculosis was the most common isolate, Mycobacterium scrofulaceum and Mycobacterium avium complex were also isolated in the present study.

    Full Text Available Abstract Background With almost 9 million new cases each year, tuberculosis remains one of the most feared diseases on the planet. Led by the STOP-TB Partnership and WHO, recent efforts to combat the disease have made considerable progress in a number of countries. However, the emergence of mutated strains of Mycobacterium tuberculosis that are resistant to the major anti-tuberculosis drugs poses a deadly threat to control efforts. Multidrug-resistant tuberculosis (MDR-TB has been reported in all regions of the world. More recently, extensively drug resistant-tuberculosis (XDR-TB that is also resistant to second line drugs has emerged in a number of countries. To ensure that adequate resources are allocated to prevent the emergence and spread of drug resistance it is important to understand the scale of the problem. In this article we propose that current methods of describing the epidemiology of drug resistant tuberculosis are not adequate for this purpose and argue for the inclusion of population based statistics in global surveillance data. Discussion Whereas the prevalence of tuberculosis is presented as the proportion of individuals within a defined population having disease, the prevalence of drug resistant tuberculosis is usually presented as the proportion of tuberculosis cases exhibiting resistance to anti-tuberculosis drugs. Global surveillance activities have identified countries in Eastern Europe, the former Soviet Union and regions of China as having a high proportion of MDR-TB cases and international commentary has focused primarily on the urgent need to improve control in these settings. Other regions, such as sub-Saharan Africa have been observed as having a low proportion of drug resistant cases. However, if one considers the incidence of new tuberculosis cases with drug resistant disease in terms of the population then countries of sub-Saharan Africa have amongst the highest rates of transmitted MDR-TB in the world. We propose

    Full Text Available Background. Tuberculosis lymphadenitis is one of the most common forms of all extrapulmonary tuberculosis. Objective. To evaluate the magnitude of M. tuberculosis from lymph node biopsy paraffin-embedded sections among suspected patients visiting the Jimma University Specialized Hospital. Method. A cross-sectional study design of histological examination among lymph node biopsy paraffin-embedded sections by Ziehl-Neelsen and hematoxylin/eosin staining technique was conducted from December, 2009, to October, 2010, at the Department of Medical Laboratory Science and Pathology. Result. Histopathological examination of the specimens by hematoxylin and eosin staining technique revealed the presence of granulomas. But for the caseation and necrosis they were present in 85% cases of nodal tissue biopsies. From those, 56.7% were from females. The presence of acid-fast bacilli was microscopically confirmed by ZN staining in 37 (61.7% of the nodal tissue biopsies. Conclusion and Recommendation. Tuberculosis lymphadenitis is significantly more common in females. Hence, attention should be given for control and prevention of extrapulmonary tuberculosis.

    Pulmonary tuberculosis is a world emergency for the World Health Organization. Techniques and new diagnosis tools are important to battle this bacterial infection. There have been many advances in all those fields, but in developing countries such as Colombia, where the resources and infrastructure are limited, new fast and less expensive strategies are increasingly needed. Artificial neural networks are computational intelligence techniques that can be used in this kind of problems and offer additional support in the tuberculosis diagnosis process, providing a tool to medical staff to make decisions about management of subjects under suspicious of tuberculosis. A database extracted from 105 subjects with precarious information of people under suspect of pulmonary tuberculosis was used in this study. Data extracted from sex, age, diabetes, homeless, AIDS status and a variable with clinical knowledge from the medical personnel were used. Models based on artificial neural networks were used, exploring supervised learning to detect the disease. Unsupervised learning was used to create three risk groups based on available information. Obtained results are comparable with traditional techniques for detection of tuberculosis, showing advantages such as fast and low implementation costs. Sensitivity of 97% and specificity of 71% where achieved. Used techniques allowed to obtain valuable information that can be useful for physicians who treat the disease in decision making processes, especially under limited infrastructure and data.

    A case of chronic idiopathic intestinal pseudo-obstruction in an English bulldog is described. The dog was presented with chronic weight loss and vomiting. An intestinal obstruction was suspected based on clinical and radiological findings. A diagnosis of chronic idiopathic intestinal pseudo-obstruction was made on the basis of full thickness intestinal biopsies. The dog was refractory to any antiemetic therapy. Necropsy revealed marked atrophy and fibrosis of the tunica muscularis, together with a mononuclear cell infiltrate extending from the duodenum to the colon. This case was presented with clinical findings consistent with visceral myopathy in humans--namely, atony and dilatation of the whole gut--but the histological findings resembled sclerosis limited to the gastrointestinal tract.

    Full Text Available Introduction: Tuberculosis (TB still remains an important public health problem in Iran. The genotyping of Mycobacterium tuberculosis isolates is expected to lead to a better understanding of M. tuberculosis transmission in Tehran, the most populated city of Iran. Materials and Methods: A total of 2300 clinical specimens were obtained from TB suspected patients who were referred to a TB center in Tehran from Jan 2014 to Dec 2016. Identification was performed using both conventional and molecular methods. The presence of resistance to rifampicin was examined by the GeneXpert MTB/RIF. The standard 15-locus mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR typing method was applied to genotype of clinical isolates. Results: Of 2300 specimens, 80 isolates were identified as M. tuberculosis by using biochemical and molecular tests. Of 80 M. tuberculosis isolates, 76 (95% had unique genotypic profiles and 4 (5% shared a profile with one or more other strains. Based on single loci variation (SLV 4 clonal complexes were observed. NEW-1 was found to be the most predominant lineage (22.5% followed by West African (1.25%, Central Asian (CAS/Delhi (1.25%, Bovis (1.25%, H37Rv (1.25% and multiple matches (1.25%. Loci MIRU10, MIRU26, MTUB21 and QUB26 were found as highly discriminative. No mutation was detected in the hotspot region of rifampicin by using GeneXpert MTB/RIF. Conclusions: Our study findings show that there was considerable genotypic diversity among M. tuberculosis isolates in Tehran. The 15-locus MIRU-VNTR showed high HGDI and could be used as a first-line genotyping method for epidemiological studies. Keywords: Mycobacterium tuberculosis, Genotyping, MIRU-VNTR, Tehran, Iran

    Full Text Available Tuberculosis (TB is a major concern in developing countries. In Brazil, few genotyping studies have been conducted to verify the number of IS6110 copies present in local prevalent strains of Mycobacterium tuberculosis, the distribution and clustering of strains. IS6110 DNA fingerprinting was performed on a sample of M. tuberculosis isolates from patients with AFB smear-positive pulmonary TB, at a hospital in Brazil. The IS6110 profiles were analyzed and compared to a M. tuberculosis database of the Houston Tuberculosis Initiative, Houston, US. Seventy-six fingerprints were obtained from 98 patients. All M. tuberculosis strains had an IS6110 copy number between 5-21 allowing for differentiation of the isolates. Human immunodeficiency virus infection was confirmed in nearly half the patients of whom data was available. Fifty-eight strains had unique patterns, while 17 strains were grouped in 7 clusters (2 to 6 strains. When compared to the HTI database, 6 strains matched isolates from El Paso, Ciudad de Juarez, Houston, and New York. Recently acquired infections were documented in 19% of cases. The community transmission of infection is intense, since some clustered strains were recovered during the four-year study period. The intercontinental dissemination of M. tuberculosis strains is suspected by demonstration of identical fingerprints in a distant country.

Methods: This study was carried out involving 975 suspected tuberculosis patients. All the specimens of patients were subjected to Ziehl-Neelsen staining, cultured on Lowenstein-Jensen medium and resistance pattern was evaluated by standard proportion method. All patients diagnosed with pulmonary tuberculosis were placed in CAT I and II under Revised National Tuberculosis Control Programme guidelines. Result: Out of 220 patients, 129 (58.7% were from CAT I and 91 (41.3% were from CAT II. Totally 44.5% were resistant to one or more than two drugs and 18.6% patients showed resistance to both isoniazid and rifampicin. The individual resistance pattern of these first line drugs were as follows: 37.7% patients were resistant to isoniazid, 22.2% to rifampicin, 8.6% to streptomycin and 10% were resistant to ethambutol. Conclusions: Our findings concluded a high prevalence of in vitro drug resistance of Mycobacterium tuberculosis isolates, especially multidrug resistant tuberculosis, in both the categories. So there is an urgent need to further study the risk factors for transmission and multidrug resistant tuberculosis in these settings.

    Tuberculosis, more than any other infectious disease, has always been a challenge, since it has been responsible for a great amount of morbidity and mortality in humans. After a steady decline in the number of new cases during the twentieth century, due to improved social and environmental conditions, early diagnosis, and the development of antituberculous medication, a stagnation and even an increase in the number of new cases was noted in the mid-1980s. The epidemiological alteration is multifactorial: global increase in developing countries; minority groups (HIV and other immunocompromised patients); and elderly patients due to an altered immune status. Other factors that may be responsible are a delayed diagnosis, especially in elderly patients, incomplete or inadequate therapy, and the emergence of multidrug-resistant tuberculosis. The course of the disease and its corresponding clinicoradiological pattern depends on the interaction between the organism and the host response. Classically, pulmonary tuberculosis has been classified in primary tuberculosis, which occurred previously in children, and postprimary tuberculosis, occurring in adult patients. In industrialized countries, however, there seems to be a shift of primary tuberculosis towards adults. Furthermore, due to an altered immunological response in certain groups, such as immunocompromised and elderly patients, an atypical radioclinical pattern may occur. The changing landscape, in which tuberculosis occurs, as well as the global resurgence, and the changed spectrum of the clinical and radiological presentation, justify a renewed interest of radiologists for the imaging features of pulmonary tuberculosis. This article deals with the usual imaging features of pulmonary tuberculosis as well as the atypical patterns encountered in immunodepressed and elderly patients. (orig.)

    Delay in diagnosis of pulmonary and other forms of tuberculosis (TB can be fatal, particularly in HIV-infected patients. Hence, techniques based on nucleic acid amplification, which are both rapid and of high specificity and sensitivity, are now widely used and recommended for laboratories that diagnose TB. In the present study, diagnostic methods based on mycobacterial DNA amplification were evaluated in comparative trials alongside tradicional bacterial methods, using negative smear samples from patients with clinically-suspected TB (sputum samples from 25 patients with suspected pulmonary TB, urine samples from two patients with suspected renal TB and cerebrospinal fluid samples from one patient with suspected meningeal TB. A specificity of 100% was achieved with DNA amplification methods and tradicional culture/identification methods, in relation to clinical findings and treatment results. For the smear-negative sputa, conventional PCR for M. tuberculosis was positive in 62% of suspected lung TB case, showing the same sensitivity as bacterial identification. Both techniques failed in the detection of extra-pulmonary samples. Nested PCR showed, after species-specific amplification, a sensitivity of 100% for M. avium and 85% for M. tuberculosis. For extra-pulmonary smear-negative samples, only Nested PCR detected M. tuberculosis and all cases were confirmed clinically. Nested PCR, in which two-step amplification reactions are performed, can identify the two most important mycobacteria in human pathology quickly and directly from clinical spicimens.

    Full Text Available Tuberculosis (TB is one of the leading causes of morbidity and mortality worldwide. Early diagnosis and treatment are key to prevent Mycobacterium tuberculosis transmission. Bronchoscopy can play a primary role in pulmonary TB diagnosis, particularly for suspected patients with scarce sputum or sputum smear negativity, and with endobronchial disease. Bronchoscopic needle aspiration techniques are accurate and safe means adopted to investigate hilar and mediastinal lymph nodes in cases of suspected TB lymphadenopathy. Tracheobronchial stenosis represents the worst complication of endobronchial tuberculosis. Bronchoscopic procedures are less invasive therapeutic strategies than conventional surgery to be adopted in the management of TB-related stenosis.We conducted a non-systematic review aimed at describing the scientific literature on the role of bronchoscopic techniques in the diagnosis and therapy of patients with TB.We focused on three main areas of interventions: bronchoscopic diagnosis of smear negative/sputum scarce TB patients, endobronchial TB diagnosis and treatment and needle aspiration techniques for intrathoracic TB lymphadenopathy. We described experiences on bronchoalveolar lavage, bronchial washing, and biopsy techniques for the diagnosis of patients with tracheobronchial and pulmonary TB; furthermore, we described the role played by conventional and ultrasound-guided transbronchial needle aspiration in the diagnosis of suspected hilar and mediastinal TB adenopathy. Finally, we assessed the role of the bronchoscopic therapy in the treatment of endobronchial TB and its complications, focusing on dilation techniques (such as balloon dilation and airway stenting and ablative procedures (both heat and cold therapies.

    Full Text Available Peritoneal tuberculosis (TB is an extrapulmonary form of presentation of tuberculosis. HIV infection is a primary risk factor for this condition. Diagnosis requires microbiological or histopathological confirmation in addition to supporting radiological imaging studies. Abdominal ultrasonography and CT are useful to obtain a radiographic diagnosis, with typical findings including diffuse peritoneal thickening, presence of ascites in varying volumes, adenopathies, and caseating nodes. We report 2 cases of patients with ascites and nodular peritoneal thickening on diagnostic images, as well as high CA-125 levels in laboratory tests. In both patients, a diagnosis of peritoneal tuberculosis was reached following a US-guided peritoneal biopsy.

    Prevalent since pre-history, human tuberculosis - caused by the pathogen Mycobacterium tuberculosis - remains a major source of death worldwide. Moreover, increasing drug resistance poses the threat of disease resurgence. However, the expanding application of genomic techniques is providing new avenues for combating this old foe. Whole-genome sequencing, comparative genomics and systems biology are generating new insights into the origins and ongoing evolution of M. tuberculosis, as well as the molecular basis for its pathogenicity. These have important implications for our perspective of the disease, development of new drugs and vaccines, and treatment of patients using existing therapeutics.

    Background Though internationally recommended, provider initiated HIV testing and counseling (PITC) of persons suspected of tuberculosis (TB) is not a policy in India; HIV seroprevalence among TB suspects has never been reported. The current policy of PITC for diagnosed TB cases may limit opportunities of early HIV diagnosis and treatment. We determined HIV seroprevalence among persons suspected of TB and assessed feasibility and effectiveness of PITC implementation at this earlier stage in the TB diagnostic pathway. Methods All adults examined for diagnostic sputum microscopy (TB suspects) in Vizianagaram district (population 2.5 million), in November-December 2010, were offered voluntary HIV counseling and testing (VCT) and assessed for TB diagnosis. Results Of 2918 eligible TB suspects, 2465(85%) consented to VCT. Among these, 246(10%) were HIV-positive. Of the 246, 84(34%) were newly diagnosed as HIV (HIV status not known previously). To detect a new case of HIV infection, the number needed to screen (NNS) was 26 among ‘TB suspects’, comparable to that among ‘TB patients’. Among suspects aged 25–54 years, not diagnosed as TB, the NNS was 17. Conclusion The seroprevalence of HIV among ‘TB suspects’ was as high as that among ‘TB patients’. Implementation of PITC among TB suspects was feasible and effective, detecting a large number of new HIV cases with minimal additional workload on staff of HIV testing centre. HIV testing of TB suspects aged 25–54 years demonstrated higher yield for a given effort, and should be considered by policy makers at least in settings with high HIV prevalence. PMID:22844467

    Full Text Available Abstract Introduction Tuberculosis of the flat bones is rare and only a small percentage involves the scapular bone. Case presentation We report a rare case of tuberculosis of the scapula in a 14-year-old. Diagnostic clues include lytic areas with low density seen in the body of the scapula involving a glenoid margin associated with typical clinical features. Treatment should include a regimen of four antitubercular drugs along with surgical debridement if required. Conclusion Although rare, tuberculosis should be suspected in patients presenting with a chronic sinus in the scapular region, particularly in the developing world.

    2015-01-01

    Metabolism underpins the physiology and pathogenesis of Mycobacterium tuberculosis. However, although experimental mycobacteriology has provided key insights into the metabolic pathways that are essential for survival and pathogenesis, determining the metabolic status of bacilli during different stages of infection and in different cellular compartments remains challenging. Recent advances—in particular, the development of systems biology tools such as metabolomics—have enabled key insights into the biochemical state of M. tuberculosis in experimental models of infection. In addition, their use to elucidate mechanisms of action of new and existing antituberculosis drugs is critical for the development of improved interventions to counter tuberculosis. This review provides a broad summary of mycobacterial metabolism, highlighting the adaptation of M. tuberculosis as specialist human pathogen, and discusses recent insights into the strategies used by the host and infecting bacillus to influence the outcomes of the host–pathogen interaction through modulation of metabolic functions.

    Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required. Although rare, case reports are available on extrapulmonary tuberculosis in allograft recipients. Here, we present a 25-year-old kidney transplant recipient who was diagnosed with lymph node tuberculosis under uncommon circumstances but who had a good outcome. This case report illustrates the difficulties in diagnosis of tuberculosis, changes in therapeutic protocols, and prognostic factors and highlights the effects of infectious complications with immunosuppressive therapy in this particular patient population.

    An important group of suspected illegal cosmetics consists of skin bleaching products, which are usually applied to the skin of the face, hands and décolleté for local depigmentation of hyper pigmented regions or more importantly, for a generalized reduction of the skin tone. These cosmetic products are suspected to contain illegal active substances that may provoke as well local as systemic toxic effects, being the reason for their banning from the EU market. In that respect, illegal and restricted substances in cosmetics, known to have bleaching properties, are in particular hydroquinone, tretinoin and corticosteroids. From a legislative point of view, all cosmetic products containing a prohibited whitening agent are illegal and must be taken off the EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin whitening cosmetics, collected by Belgian inspectors at high risk sites such as airports and so-called ethnic cosmetic shops, were analyzed and 59% were classified as illegal. The whitening agents mostly detected were clobetasol propionate and hydroquinone, which represent a serious health risk when repeatedly and abundantly applied to the skin.

    BCG (Bacille Calmette-Guérin) vaccination is included in the immunization schedule for tuberculosis endemic countries with a global coverage at birth close to 90% worldwide. BCG was attenuated from Mycobacterium bovis almost a century ago, and provides a strong protection against disseminated forms of the disease, though very limited against pulmonary forms of tuberculosis, responsible for transmission. Novel prophylactic tuberculosis vaccines are in clinical development either to replace BCG or to improve its protection against respiratory forms of the disease. There are limitations understanding the immunological responses involved and the precise type of long-lived immunity that new vaccines need to induce. MTBVAC is the first and only tuberculosis vaccine candidate based on live-attenuated Mycobacterium tuberculosis in clinical evaluation. MTBVAC clinical development plans to target tuberculosis prevention in newborns, as a BCG replacement strategy, and as secondary objective to be tested in adolescents and adults previous vaccinated with BCG.

    Gastric surgery is commonly performed to remove foreign bodies and correct gastric dilatation-volvulus and is less commonly performed to treat gastric ulceration or erosion, neoplasia, and benign gastric outflow obstruction. Intestinal surgery, although commonly performed by veterinarians, should never be considered routine. The most common procedures of the small intestinal tract performed in dogs and cats include enterotomy and resection/anastomosis. Surgery of the large intestine is indicated for lesions causing obstruction, perforations, colonic inertia, or chronic inflammation.

    No study reported in the literature comprehensively compares findings on neonatal abdominal radiographs with sonography. To compare the findings on abdominal radiographs and sonograms in infants in intensive care, to better understand how the various intestinal gas patterns on radiographs relate to the spectrum of appearances on sonography and, second, to evaluate the ability of sonography to differentiate necrotizing enterocolitis from other intestinal pathology. We prospectively evaluated sonograms and radiographs, blinded to the other modality and to clinical information. Patients' charts were reviewed by a third blinded reader and used as a reference standard for diagnosis. We made associations between sonographic findings, radiographic intestinal gas patterns and clinical diagnoses. We included 75 infants with gestational ages between 23 weeks and 41 weeks. Sonographic abnormalities were present in infants with all radiographic intestinal gas patterns, including normal patterns. We only saw absent intestinal perfusion and fluid collections on sonography (suggesting intestinal necrosis and sealed perforation) in infants with intestinal dilatation with elongation on radiographs. Separation of intestinal loops on radiographs was most commonly caused by reasons other than intestinal wall thickening. Increased intestinal echogenicity or free fluid with echoes on sonography correlated with a diagnosis of necrotizing enterocolitis, whereas anechoic free fluid correlated with absence of necrotizing enterocolitis. Sonography is complementary to radiographs in infants with suspected intestinal pathology, with a spectrum of appearances seen on each modality. Some sonographic findings either strongly suggest necrotizing enterocolitis or supply evidence against this diagnosis.

    of pulmonar disease is rare in Brasil, therefore causes a diagnostic dilemma as it mimics colonic malignancy and Crohn's disease. METHODS: Between 1969 and 1989, eight patients with isolated hypertrophic ileocecal tuberculosis were treated by surgery in the Gastroenterology Surgery Department of the HSPE-FMO. The most common complaint among them was abdominal pain (100% with associated symptoms of weight loss (62.5%; nausea, vomiting, fever and general weekness appeared in half of the patients. A right iliac fossa mass was present in seven (87.5% of them. The mean duration of symptoms was 14.7 month (range 5-36 months. In all eight patients chest x-rays were negative for tuberculosis. Barium contrast studies showed abnormalities in all cases, but these could not be distinguished from carcinoma. Colonoscopy was helpful in establishing the diagnosis of suboclusive lesions of the ileocecal regions in three patients. Tuberculosis diagnosis was suspected in two of them because ofr the presence of granulomas in colonic biopsy material . RESULTS: Six patients were submitted to elective right hemicolectomy. The two remaining with suspect of tuberculosis were operated with signals of intestinal occlusion, and underwent a limited ileocaecal resection.The positive diagnosis of intestinal tuberculosis was made in all the patients by identification of acid-fast bacilli and by the presence of caseating granulomas in intestinal or lymph node tissue on histological examination. The outcome in all of them was favorable. They received treatment with three antituberculosis drugs over a twelve month period. CONCLUSION: Hypertrophic ileocecal tuberculosis must still be considered in the differential diagnosis of abdominal pathology localized in the right lower quadrant.

    Full Text Available Persons infected with the Human Immunodeficiency Virus (HIV are particularly susceptible to tuberculosis, either by latent infection reactivation or by a primary infection with rapid progression to active disease. This study was done to determine the frequency of tuberculosis infection among Iranian patients with HIV/AIDS. A total of 262 HIV/AIDS patients attending all three HIV/AIDS health care centers of Tehran, Iran were enrolled in this study. A detailed history and physical examination were obtained from all HIV patients suspected of having pulmonary M. tuberculosis. A positive PPD skin test was used as a diagnostic parameter for probability of TB infection. Out of 262 HIV/AIDS patients, a total of 63 (24% were shown to have the tuberculosis infection based on a positive PPD skin test. Of the patients with positive PPD skin test, 22 (35% had pulmonary Tuberculosis, 2 (3.2% had extrapulmonary tuberculosis, and 39 (53% had no evidence of M. tuberculosis infection (latent infection. Also 8 (12.7% had history of long term residence in a foreign country, 32 (50.8% were exposed to an index case, and 9 (14.3% had past history of pulmonary tuberculosis, while only 33.3% had clinical manifestations of TB (active disease. There was no resistant case of tuberculosis. Our study showed that near 24% of Iranian patients with HIV/AIDS were infected with M. tuberculosis. This finding denotes the need to improve the diagnostic and preventive measures, and also prompt treatment of this type of infection in the HIV infected individuals.

    Vaccination with Bacillus Calmette-Guérin (BCG) is used in many countries as protection against tuberculosis. Studies have suggested that BCG may also have non-specific effects, reducing non-tuberculosis mortality, morbidity, and atopic manifestations. In this study, we evaluated the effect of neonatal BCG vaccination on allergic sensitization and suspected food allergy at 13 months of age. The Danish Calmette Study was conducted from 2012 to 2015 at three Danish hospitals. Within 7 days of birth, the 4262 newborns of 4184 included mothers were randomized 1:1 to BCG or to a no-intervention control group. Exclusion criteria were gestational age BCG group and 6.1% (126/2061) of the control group suspected food allergy, resulting in a risk ratio comparing BCG-vaccinated children with control children of 0.91 (95% CI 0.71-1.16). Among 1370 blood samples, sensitization (Phadiatop Infant >0.35 kUA/L) was found in 55 of 743 (7.4%) children in the BCG group and 50 of 627 (8.0%) of the control group (risk ratio 0.94 [0.65-1.36]). In this randomized clinical trial, neonatal BCG had no significant effect on suspected food allergy or on sensitization at 13 months of age. © 2017 EAACI and John Wiley and Sons A/S.

    Pyogenic spinal infection continues to represent a worldwide problem. In approximately one-third of patients with pyogenic spondylodiscitis, the infectious agent is never identified. Of the cases that lead to organismal identification, bacteria are more commonly isolated from the spine rather than fungi and parasites. This study applied universal prokaryotic 16S rRNA PCR as a rapid diagnostic tool for the detection of bacterial agents in specimens from patients suspected of pyogenic spondylodiscitis. Gram and Ziehl-Neelsen staining were used as a preliminary screening measure for microbiologic evaluation of patient samples. PCR amplification targeting 16S rRNA gene was performed on DNA extracted from 57 cases including specimens from epidural abscesses, vertebral, and disc biopsies. Positive samples were directly sequenced. MRI findings demonstrated that disc destruction and inflammation were the major imaging features of suspected pyogenic spondylodiscitis cases, as 44 cases showed such features. The most common site of infection was the lumbar spine (66.7%), followed by thoracic spine (19%), the sacroiliac joint (9.5%), and lumbar-thoracic spine (4.8%) regions. A total of 21 samples amplified the 16S rRNA -PCR product. Sanger sequencing of the PCR products identified the following bacteriological agents: Mycobacterium tuberculosis ( n = 9; 42.9%), Staphylococcus aureus ( n = 6; 28.5%), Mycobacterium abscessus ( n = 5; 23.8%), and Mycobacterium chelonae ( n = 1; 4.8%). 36 samples displayed no visible 16S rRNA PCR signal, which suggested that non-bacterial infectious agents (e.g., fungi) or non-infectious processes (e.g., inflammatory, or neoplastic) may be responsible for some of these cases. The L3-L4 site (23.8%) was the most frequent site of infection. Single disc/vertebral infection were observed in 9 patients (42.85%), while 12 patients (57.15%) had 2 infected adjacent vertebrae. Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP

    Full Text Available Background. Tuberculosis (TB is a major cause of morbidity and mortality globally. Many cases are diagnosed on autopsy and a subset of patients may require surgical intervention either due to the complication or sequelae of TB. Materials and Methods. 40 cases of resected lung specimens following surgery or autopsy in which a diagnosis of pulmonary tuberculosis was made were included. Histopathological pattern analysis of pulmonary tuberculosis along with associated nonneoplastic changes and identification of Mycobacterium tuberculosis bacilli was done. Results. The mean age of diagnosis was 41 years with male predominance (92.5%. Tuberculosis was suspected in only 12.1% of cases before death. Seven cases were operated upon due to associated complications or suspicion of malignancy. Tubercular consolidation was the most frequent pattern followed by miliary tuberculosis. The presence of necrotizing granulomas was seen in 33 cases (82.5%. Acid fast bacilli were seen in 57.5% cases on Ziehl-Neelsen stain. Conclusion. Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.

    Malawi is a low-income country in sub-Saharan Africa with limited health care infrastructure and high prevalance of HIV and tuberculosis. This study aims to determine the characteristics of patients presenting to Queen Elizabeth Central Hospital Oncology Unit, Blantyre, Malawi, who had been treated for tuberculosis before they were diagnosed with cancer. Clinical data on all patients presenting to the oncology unit at Queen Elizabeth Central Hospital from 2010 to 2014 after a prior diagnosis of tuberculosis were prospectively recorded, and a descriptive analysis was undertaken. Thirty-four patients who had been treated for tuberculosis before being diagnosed with cancer were identified between 2010 and 2014, which represents approximately 1% of new referrals to the oncology unit. Forty-one percent of patients were HIV positive. Mean duration of tuberculosis treatment before presentation to the oncology unit was 3.6 months. The most common clinical presentation was a neck mass or generalized lymphadenopathy. Lymphoma was the most common malignancy that was subsequently diagnosed in 23 patients. Misdiagnosis of cancer as tuberculosis is a significant clinical problem in Malawi. This study underlines the importance of closely monitoring the response to tuberculosis treatment, being aware of the possibility of a cancer diagnosis, and seeking a biopsy early if cancer is suspected.

    Full Text Available Despite the high prevalence of tuberculosis in adults and children, the congenital and perinatal forms of tuberculosis are rare. In Brazil, there has been only one published case of congenital tuberculosis and two cases of the perinatal form of this disease. We report a case of perinatal tuberculosis presenting with pneumonia. Alcohol-acid-resistant bacilli were found in the gastric lavage. Diagnosis of this disease presentation requires a high index of suspicion.

    A retrospective study was carried out by reviewing all suspected cases of domestic animal poisoning attributed to pesticides, reported to the Milan Poison Control Centre (MPCC) between January 2011 and December 2013. During this period, pesticides were found to be responsible for 37.3% of all suspected poisoning enquiries received (815). The most commonly species involved was the dog (71.1% of calls) followed by the cat (15.8%), while a limited number of cases involved horses, goats and sheep. Most cases of exposure (47.1%) resulted in mild to moderate clinical signs. The outcome was reported in 59.9% of these cases, with death occurring in 10.4% of them. Insecticides (40.8%) proved to be the most common group of pesticides involved and exposure to pyrethrins-pyrethroids accounted for the majority of calls. According to the MPCC data, there has been a decrease in the number of suspected poisonings cases attributed to pesticides that have been banned by the EU, including aldicarb, carbofuran, endosulfan and paraquat. In contrast, there has been an increase of suspected poisoning cases attributed to the neonicotinoids, imidacloprid and acetamiprid, probably due to their widespread use in recent years. Cases of suspected poisoning that involved exposure to rodenticides accounted for 27.6% of calls received by the MPCC and anticoagulant rodenticides were the primary cause of calls, with many cases involving brodifacoum and bromadiolone. Herbicides were involved in 14.2% of calls related to pesticides and glyphosate was the main culprit in cases involving dogs, cats, horses, goats and sheep. As far as exposure to molluscicides (11.5%) and fungicides (5.9%), most of the cases involved dogs and the suspected poisoning agents were metaldehyde and copper compounds respectively. The data collected are useful in determining trends in poisoning episodes and identifying newly emerging toxicants, thus demonstrating the prevalence of pesticides as causative agents in animal

    Conclusions: Intestinal lymphangiectasia should be suspected when there is a clinical picture of chronic diarrhea and protein-losing enteropathy accompanied with edema at any level, as well as hypoalbuminemia, hypocalcemia, lymphopenia, hypogammaglobulinemia, and hypocholesterolemia, which are the main biochemical findings of this pathology. All children presenting with intestinal lymphangiectasia should undergo an upper gastrointestinal series with bowel transit time and endoscopy with biopsies taken at the level of the duodenum. Treatment includes diet and the periodic administration of albumin and gamma globulin.

    Purpose: To evaluate the various radiological abnormalities in patients with proven esophageal tuberculosis. Material and Methods: The case records of 23 patients with proven esophageal tuberculosis were evaluated retrospectively for various radiological abnormalities. Twenty-two patients had secondary involvement of esophagus in the form of direct extension of mediastinal and pulmonary tuberculosis or spinal tuberculosis. Only 1 patient had primary involvement of the esophagus with no evidence of disease elsewhere. The diagnosis was confirmed by endoscopic and CT-guided biopsy/aspiration cytology in 7 and 6 cases, respectively. Diagnosis was made on the basis of surgical biopsy of lymph node and autopsy in 1 patient each. In the remaining 8 patients the diagnosis was based on radiological and endoscopic findings and the response to antituberculous treatment. Results: Chest radiography (CXR) was abnormal in 65% patients. While the findings were non-conclusive for esophageal tuberculosis, characteristic lesions of tuberculosis in lungs or spine were suggestive of tuberculous etiology. In 15 patients, CT of the chest confirmed the corresponding CXR findings and also showed additional findings of mediastinal lymphadenopathy when CXR was normal. Fourteen patients showed mediastinal lymphadenopathy on CT of the chest. In all these patients, more than one group of lymph nodes was involved. The characteristic hypodense center of lymph nodes suggestive of tuberculosis was seen in 12 patients. Radiological abnormalities seen in barium swallow examination were extrinsic compression, traction diverticula, strictures, sinus/fistulous tracts, kinking and pseudotumor mass of esophagus in decreasing order of frequency. The middle third of the esophagus was found to be the most frequent site of involvement.

    2017-06-01

    Full Text Available BACKGROUND Six countries in Asia account for 60% of the total new tuberculosis cases occurring globally with India leading the count. India accounts for approximately 25% of global incidence of tuberculosis with almost 2 deaths every 3 minutes due to tuberculosis alone. GeneXpert is a comparatively newer diagnostic test for detecting Mycobacterium tuberculosis complex, which uses the PCR to test specimens and simultaneously detects resistance to rifampicin, thus allowing diagnosis of DR-TB within a couple of hours. The present study was conducted to find the sensitivity and specificity of GeneXpert in extrapulmonary samples (lymph node and pleural fluid and compare the results with those of smear and AFB culture with an aim to provide rapid diagnostic test to patients with suspected extrapulmonary tuberculosis. MATERIALS AND METHODS A retrospective data analysis of reports of extrapulmonary samples (lymph node and pleural fluid of 45 patients sent for AFB smear, GeneXpert and AFB culture during routine investigations were studied. RESULTS Sensitivity of GeneXpert in lymph node samples was found to be 94.12% and specificity was 30.77% with positive predictive value of 64% and negative predictive value of 80%. The sensitivity of GeneXpert in pleural fluid samples was found to be 60% with 100% specificity. The positive predictive value was 100% and negative predictive value was 83.33%. CONCLUSION The overall sensitivity of GeneXpert was 96.67% with specificity of 100%, positive predictive value of 100% and negative predictive value of 83.33%. Thus, it is a valuable test for diagnosing extrapulmonary tuberculosis at the earliest with an added advantage of detecting resistance for rifampicin.

    Child physical abuse is an important cause of pediatric morbidity and mortality and is associated with major physical and mental health problems that can extend into adulthood. Pediatricians are in a unique position to identify and prevent child abuse, and this clinical report provides guidance to the practitioner regarding indicators and evaluation of suspected physical abuse of children. The role of the physician may include identifying abused children with suspicious injuries who present for care, reporting suspected abuse to the child protection agency for investigation, supporting families who are affected by child abuse, coordinating with other professionals and community agencies to provide immediate and long-term treatment to victimized children, providing court testimony when necessary, providing preventive care and anticipatory guidance in the office, and advocating for policies and programs that support families and protect vulnerable children.

    Full Text Available In spite of an array of effective antibiotics, tuberculosis is still very common in developing countries where overcrowding, malnutrition and poor hygienic conditions prevail. Over the past 30 years associated HIV infection has worsened the situation by increasing the infection rate and mortality of tuberculosis. Of those diseases caused by a single organism only HIV causes more deaths internationally than tuberculosis. The tubercle bacillus probably first infected man in Neolithic times, and then via infected cattle, but the causative Mycobacteriacea have been in existence for 300 million years. Droplet infection is the most common way of acquiring tuberculosis, although ingestion (e.g. of infected cows’ milk may occur. Tuberculosis probably originated in Africa. The earliest path gnomonic evidence of human tuberculosis in man was found in osteo-archaeological findings of bone tuberculosis (Pott’s disease of the spine in the skeleton of anEgyptian priest from the 21st Dynasty (approximately 1 000 BC. Suggestive but not conclusiveevidence of tuberculotic lesions had been found in even earlier skeletons from Egypt and Europe. Medical hieroglyphics from ancient Egypt are silent on the disease, which could be tuberculosis,as do early Indian and Chinese writings. The Old Testament refers to the disease schachapeth, translated as phthisis in the Greek Septuagint. Although the Bible is not specific about this condition, tuberculosis is still called schachapeth in modern Hebrew. In pre-Hippocratic Greece Homer did not mention phthisis, a word meaning non-specific wasting of the body. However. Alexander of Tralles (6th century BC seemed to narrow the concept down to a specific disease, and in the Hippocratic Corpus (5th-4th centuries BC phthisis can be recognised as tuberculosis. It was predominantly a respiratory disease commonly seen and considered to be caused by an imbalance of bodily humours. It was commonest in autumn, winter and spring

  10. Suspects in criminal investigations of rape

    2014-01-01

    Full Text Available Investigations of sexual assaults mostly focus on victims and their credibility, which may cause lack of firm evidence in relation to suspects. Given the fact that the criminal offence of rape is characterised by a high incidence of false reports and accusations, frequently indicating specific persons as the perpetrators, certain caution is necessary in the investigation in order to avoid false accusations and/or convictions. As regards the personality of the rapist and motives for committing a forcible sexual act, certain types or rather certain categories of perpetrators can be distinguished, although it should be noted that a large number of rapists do not belong to one category only, but rather combine characteristics of several different types. During a criminal investigation it is of vital importance to differentiate between a rape as a surprise attack and a rape as abuse of trust, as they are compatible with the nature of the suspect's defence. The suspect shall be subjected to a forensic examination in the course of the investigation in order to find traces which prove vaginal, anal or oral penetration, coerced sexual intercourse and identity of the rapist. While conducting an interrogation of a suspected rapist, a crime investigating officer shall use either factual or emotional approach to his interviewee, depending on his psychological and motivational characteristics. In this regard, the factual approach is believed to be more efficient with anger rapists and sadistic rapists, whereas the compassionate approach gives good results with the gentlemen-rapists and partly with the power asserting rapists.

    A 76-year-old woman with a 10-year history of chronic glomerulonephritis was treated at a clinic after presenting with a gradual worsening of the renal function. The patient had no history of tuberculosis. She was subsequently hospitalized for uremic symptoms and treated with internal shunt insertion and dialysis. Thyroid ultrasonography was performed to screen for secondary hyperparathyroidism, which revealed a calcified thyroid mass and cervical lymph node swelling. Fine-needle aspiration biopsy was thus conducted to assess suspected thyroid cancer. The cytological findings showed few follicular epithelial cells, without any signs of malignancy. However, a diagnosis of thyroid cancer continued to be strongly suspected based on the imaging features. Total thyroidectomy and bilateral cervical regional lymph node dissection were therefore performed, and the pathological examination of the thyroidectomy specimen disclosed scattered epithelioid granulomas with caseous necrosis in the entire right lobe as well as the cervical lymph nodes. Based on these findings, the patient was diagnosed with thyroid tuberculosis. As the symptoms and imaging findings of tuberculosis are nonspecific in elderly patients, it is necessary to consider this disease in this population. We therefore propose the inclusion of thyroid tuberculosis in the differential diagnosis of elderly patients who present with malignant thyroid tumors on aspiration biopsy cytology, regardless of whether or not they have a previous history of tuberculosis.

    The purpose of this study was to determine the technical capacity and diagnostic accuracy of 3D time-of-flight magnetic resonance angiography (MRA) in suspected cerebral vasculitis in a retrospective analysis of MRA and digital subtraction angiography (DSA) in 14 young patients with clinical and/or radiological suspicion of cerebral vasculitis. A total of nine arteries were evaluated in each patient. Consensus review of DSA by three observers was the reference standard. The sensitivity for detecting a stenosis varied from 62 to 79% for MRA and from 76 to 94% for DSA, depending on the observer. The specificity for detecting a stenosis varied from 83 to 87% for MRA and from 83 to 97% for DSA. Using the criterion ''more than two stenoses in at least two separate vascular distributions'' to consider the examination as being true positive, the false-positive rates for MRA and DSA were comparable. MRA plays a role as the first angiographical examination in the diagnostic work-up of suspected cerebral vasculitis. When more than two stenoses in at least two separate vascular distributions are depicted on MRA, DSA is not expected to add a significant diagnostic contribution in a patient with suspected cerebral vasculitis. DSA remains necessary when MRA is normal or when less than three stenoses are seen. (orig.)

    Extensively drug-resistant tuberculosis (XDR-TB) has recently been identified as a major global health threat. The aim of this study was to evaluate the presence of XDR-TB among Mycobacterium tuberculosis isolates in Morocco and its association with demographic, clinical and epidemiological features. A total of 524 patients from the Moroccan National Tuberculosis Reference Laboratory, representative of all of the geographic regions, were subject to first-line drug susceptibility testing (DST). Subsequently, 155 isolates found to be multidrug-resistant tuberculosis (MDR-TB) underwent second-line DST. Moreover, to enhance our understanding of the genetic basis of these drug-resistant strains, drug resistance-associated mutations were investigated in isolates either identified as pre-XDR- and XDR-TB or suspected resistant using the GenoType ® MTBDRsl V1.0 assay. In this study, 4 (2.6%) XDR-TB and 18 (11.6%) pre-XDR-TB isolates were identified. Agreement between the MTBDRsl assay results and phenotypic DST was 95.2% for ofloxacin, 81.0% for kanamycin and 95.2% for amikacin. To the best of our knowledge, this is the first study to evaluate the frequency of XDR-TB in Morocco. These results highlight the need to reinforce the TB management policy in Morocco with regard to control and detection strategies in order to prevent further spread of XDR-TB isolates.

    Full Text Available Abstract This work describes the experience at a tuberculosis clinical laboratory where relatively new TB diagnosis technologies; nucleic acid detection of two target strands, IS6110 and devR, by PCR and microscopic observation drug susceptibility (MODS were used. The LJ culture was the gold standard. This evaluation was done from August 2007 to July 2009 on 463 sputum samples of tuberculosis suspects at a specialized tuberculosis clinic in Delhi, India. None of the tests we evaluated can accurately detect the presence or absence of Mycobacterium tuberculosis in all the samples and smear microscopy was found to be the most reliable assay in this study. The PCR assay could detect down to 2 pg of H37Rv DNA. Sensitivity, specificity was 0.40, 0.60 and 0.19, 0.81 for smear positive (n = 228 and negative samples (n = 235 respectively. In the MODS assay, sensitivity, specificity of 0.48, 0.52 and 0.38, 0.76 was observed for smear positive and negative samples. Sputum smear microscopy had sensitivity of 0.77 and specificity of 0.70.

    Cutaneous tuberculosis (CTB) is still difficult to diagnose due to its varied clinical presentation and limitations of diagnostic methods. The aim of this study was to evaluate the results of diagnostic laboratory tests available for CTB. Twenty-six skin biopsy specimens belonging to clinically suspected cases of CTB were studied retrospectively. The specimens were divided into two portions, one part processed for histopathological evaluation and the other was used for microscopy and inoculation for the isolation of mycobacteria. Polymerase chain reaction (PCR) technique was applied to 14 of 26 specimens to detect Mycobacterium tuberculosis complex (MTBC) DNA. Of the 26 biopsy specimens, 11 were confirmed as CTB by identification of MTBC in culture and/or histopathologic affirmation. Of these, four were lupus vulgaris, four were TB verrucosa cutis, one was scrofuloderma, one was primary inoculation TB, and one was periorifical CTB. Culture for mycobacteria was positive for five (45.45%) specimens, while histopathologic affirmation was obtained in ten (90.90%) specimens. Acid-fast Bacilli were not demonstrated in any of the specimens on microscopic examination. The PCR was found to be applied to six of the 11 specimens diagnosed as CTB and was positive in two specimens (33.3%), which were positive for growth in culture and histopathological correlation. The recovery rate of MTBC from biopsy specimens was found to be satisfactory for CTB with histopathological correlation, but the combination of culture with a rapid method, PCR, may improve the diagnostic rate.

  18. Intestinal Barrier and Behavior.

    Science.gov (United States)

    Julio-Pieper, M; Bravo, J A

    2016-01-01

    The intestinal barrier function contributes to gut homeostasis by modulating absorption of water, electrolytes, and nutrients from the lumen into the circulation while restricting the passage of noxious luminal substances and microorganisms. Chronic conditions such as rheumatoid arthritis, inflammatory bowel disease, and celiac disease are associated to intestinal barrier dysfunction. Here, the hypothesis is that a leaky intestinal wall allowing for indiscriminate passage of intraluminal compounds to the vascular compartment could in turn lead to systemic inflammation. An increasing number of studies are now investigating the association between gut permeability and CNS disorders, under the premise that translocation of intestinal luminal contents could affect CNS function, either directly or indirectly. Still, it is unknown whether disruption of intestinal barrier is a causative agent or a consequence in these situations. Here, we discuss the latest evidence pointing to an association between increased gut permeability and disrupted behavioral responses. © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate lymph node tuberculosis (LNT) cases in two provinces in Turkey with different demographic and socioeconomic characteristics. A total of 109 LNT cases were reviewed retrospectively. The cases were analyzed and compared for symptoms, findings, age, vaccination status, and diagnostic procedures. Socioeconomic conditions were also assessed for the two provinces. A palpable cervical node was considered a significant predictor for all LNT. Mediastinal lymph node involvement was found to be common in cases of pulmonary manifestation of LNT. Female patients were predominantly from the Van Province, while older patients were found to be from Izmir Province. LNT should be suspected in lymphadenitis patients of all age-groups especially in young adolescents with cervical lymph node enlargements. In the presence of mediastinal lymphadenopathy, pulmonary tuberculosis should be investigated.

    Full Text Available The tuberculosis of the hand and the wrist is a rare entity. Affecting the scapholunate joint is exceptional. It is usually diagnosed at an advanced stage of carpal destruction, due to slowly development of the symptoms. We report the case of a 58-year-old female, presenting as wrist pain for 3 months. Clinical study showed a local swelling in the left wrist, the mobility of the wrist was normal but painful at the end of motion. The diagnosis of osteoarticular tuberculosis was suspected after radiological and biological study then confirmed after histological study. Antibacillary chemotherapy during 12 months promoted healing and good outcome.

    Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish. Copyright © 2013 Elsevier Inc.

    The radiologic knowledge of tuberculosis-associated lung disease is an essential tool in the clinical diagnosis of tuberculosis. Chest radiography is the primary imaging method, but the importance of CT is still increasing, as CT is more sensitive in the detection of cavitation, of hilar and mediastinal lymphadenopathie, of endobronchial spread and of complications in the course of the disease. In addition, CT has been proven as a valuable technique in the assessment of tuberculosis activity, especially in patients where M. tuberculosis has not been detected in the sputum or in patients with multidrug-resistant tuberculosis. Depending on the immune status of the patient, the morphologic spectrum of tuberculosis is quite variable. Early diagnosis of tuberculosis is essential to prevent further spread of the disease.

    Tuberculosis remains the single highest contributor to the world's morbidity and mortality. Early diagnosis and prompt treatment is essential to prevent its transmission. To see the treatment response of anti tuberculosis drugs in smear negative patients and study the predictors of culture positive among smear negative tuberculosis patients. Ninety four sputum smear negative patients clinically and radiologically suggestive of tuberculosis were selected. These patients were put on anti tuberculosis drugs without waiting for their culture results. They were then followed for 8 months to see their treatment outcome. A total of 94 smear negative patients were selected and given anti tuberculosis treatment. Of these 37(39%) were culture positive and 57(61%) were culture negative. Of the 37 culture positive patients 36(97%) showed clinical or radiological improvement as compared to 46(81%) out of 57 in culture negative cases. Symptoms of cough with sputum production was significantly associated with culture positivity. On x-ray chest moderate lesion with diffuse infiltration was more common finding in 64% while extensive and cavitatory lesion was seen in 24% of all cases. Association of extensive and cavitatory lesion were seen in culture positive group. Response to anti tuberculosis drugs in sputum smear negative tubercolosis suspects was found to be effective in majority of the patients. Cough, sputum and extensive cavitatory lung lesion were the predictors of culture positive cases. There is need to train physicians on the use of anti tuberculosis therapy in smear negative suspected pulmonary tuberculosis cases, especially if they have productive cough and cavitatory lung lesions.

    Mycobacterium tuberculosis is the leading cause of death worldwide from a single bacterial pathogen. The World Health Organization estimates that annually 1 million children have tuberculosis (TB) disease and many more harbor a latent form. Accurate estimates are hindered by under-recognition and challenges in diagnosis. To date, an accurate diagnostic test to confirm TB in children does not exist. Treatment is lengthy but outcomes are generally favorable with timely initiation. With the End TB Strategy, there is an urgent need for improved diagnostics and treatment to prevent the unnecessary morbidity and mortality from TB in children. Copyright © 2017 Elsevier Inc.

    Tuberculosis (TB) patients must be hospitalized while the smear of sputum is positive because TB spreads through air. Cooperation of a patient is important in order to complete the treatment of TB. However, a small number of patients are noncooperative for the treatment and may sometimes refuse it. At this symposium, we discussed about whether we could restrict the human rights of noncooperative TB patients. Although the patients' human rights must be protected, we also have to protect the human rights of people who may receive TB infection. The balance of the both people's rights is fully considered in the TB control policy. It is epoch-making that the TB society took up the theme about the human rights' restriction of TB patients. Five speakers presented their papers from each position. There were presentations about the scientific evidence of isolation, the actual cases, the situation of the United States, and the legal view on the human rights' restriction of TB patients. The present situation and the legal problems in Japan became clear at this symposium. We need further discussion about the human rights' restriction of TB patients for the revision of the Tuberculosis Protection Act and have to obtain the national consensus on it. 1. The evidence for isolation: Emiko TOYODA (International Medical Center of Japan) To determine appropriate periods of respiratory isolation, available biological, clinical, and epidemiological issues and data were studied. Although absolute lack of infectiousness requires consecutive culture negative and it takes too long and impractical periods. There seems to be no established evidence for noncontagiousness after 2 to 3 weeks effective treatment. Practically conversion to 3 negative consecutive smear results may used as a surrogate for noninfectiousness, even though a small risk of transmission still be present. Chemical isolation has been more important and administration with DOT should be indicated to keep compliance. 2

    Extra-pulmonary tuberculosis (TB) is more common in renal allograft recipients and may present with dissemination or an atypical features. We report a renal allograft recipient with intestinal TB presenting 3 years after transplantation with persistent fever, weight loss, diarrhea, abdominal pain and mass in the abdomen with intestinal obstruction. He was diagnosed to be having an ileocolic intussusception which on resection showed a granulomatous inflammation with presence of acid-fast bacilli (AFB) typical of Mycobacterium tuberculosis. In addition, AFB was detected in the tracheal aspirate, indicating dissemination. He received anti-TB therapy (ATT) from the fourth postoperative day. However, he developed a probable immune reconstitution inflammatory syndrome (IRIS) with multiorgan failure and died on 11(th) postoperative day. This is the first report of intestinal TB presenting as intussusception in a renal allograft recipient. The development of IRIS after starting ATT is rare in renal allograft recipients. This report highlights the need for a high index of suspicion for diagnosing TB early among renal transplant recipients and the therapeutic dilemma with overwhelming infection and development of IRIS upon reduction of immunosuppression and starting ATT.

    Full Text Available Tuberculosis (TB is a problem of public health that causing high morbidity and mortality rates in various countries in the world. The diagnosis of pulmonary tuberculosis in adults can be established based on the discovery of M. tuberculosis on smear or culture of sputum. Culture is the gold standard but the availlable method is time consuming, it is need minimal eight weeks. Microscopic observation drug susceptibility assay (MODS is one of methods for M. tuberculosis culture using liquid medium that can be a simultaneously test for M. tuberculosis drug sensitivity. The purpose of this study was to determine the conformity of the MODS method compared with Ogawa method for cultivation of M. tuberculosis in pulmonary TB patients. The cross sectional research has been conducted at Clinical Pathology Department of Dr. Hasan Sadikin Hospital, Bandung and examination of the specimen done at Health Laboratory Development Unit (BPLK, West Java Province between April to August 2010. The subjects were patients who diagnosed as pulmonary TB suspect. Each collected specimen was cultured in liquid media MODS and solid media Ogawa. To analyze the conformity of MODS and Ogawa method, Kappa coefficient of agreement was used. There were 172 specimens collected from 133 subjects. The conformity between culture results of M. tuberculosis in MODS method and in Ogawa’s method using Kappa coefficient, was high (Kappa index 0.91. The difference of growth time of M. tuberculosis significant (p=0.000, in MODS was 10.1 days (range 4–21 days and in Ogawa method was 24.8 days (range 14–35 days. Conclusion, MODS and Ogawa’s method have the relatively similar diagnostic success rate, the advantage of MODS method is, the growth of M. tuberculosis is faster than in Ogawa method.

    A 10-year-old female neutered cross-breed dog presented with a 4-month history of chronic intermittent diarrhoea and vomiting. Abdominal ultrasound showed dilated loops of small intestine and a suspected faecolith. Exploratory surgery revealed a caecal impaction and a typhlectomy was performed. Histopathological examination of caecal and full thickness small intestine sections demonstrated atrophy of smooth muscle fibres as well as an influx of plasma cells, lymphocytes and macrophages, and mild lymphoplasmacytic and eosinophilic enteritis. This combination of caecal impaction and chronic intestinal pseudo-obstruction has not been reported previously in the dog.

  14. Mycotoxins and the intestine

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Fungal biochemical pathways can yield various compounds that are not considered to be necessary for their growth and are thus referred to as secondary metabolites. These compounds have been found to have wide ranging biological effects and include potent poisons (mycotoxins. Mycotoxins invariably contaminate crops and (thus animal feeds. The intestine is the key link between ingested mycotoxins and their detrimental effects on the animal. Effects on the intestine, or intestinal environment, and immune system have been reported with various mycotoxins. These effects are almost certainly occurring across species. Most, if not all, of the reported effects of mycotoxins are negative in terms of intestinal health, for example, decreased intestinal cell viability, reductions in short chain fatty acid (SCFA concentrations and elimination of beneficial bacteria, increased expression of genes involved in promoting inflammation and counteracting oxidative stress. This challenge to intestinal health will predispose the animal to intestinal (and systemic infections and impair efficient digestion and absorption of nutrients, with the associated effect on animal productivity.

  15. Prevalence of Pulmonary Tuberculosis among Household Contacts in Hyderabad, Sindh: Active Contact Tracing in Children with Tuberculosis

    Sheikh, M.A.; Shah, S.A.A.

    2017-01-01

    Background: Tuberculosis (TB) in children is clearly linked to TB in adults therefore active household contact tracing is an important method of early diagnosis and treatment particularly in high-TB-burden countries. Objectives: To estimate the prevalence of TB among household contacts of children suffering from tuberculosis using active contact tracing and linking them to TB program for treatment. Subjects and Methods: A total of 125 children suffering from active tuberculosis (index cases)aged 12 years or less were randomly selected from the outpatient department of a tertiary care hospital of Hyderabad. Using their home address, all house hold members of the index cases (sharing one kitchen) were identified. The households were visited by a team including a doctor and the supported staff and were screened for TB using history, physical examination, sputum for AFB and X-ray of chest. Clinical suspects were divided in to two populations, equal to or less than 12 years of age and greater than this age. All suspected cases were brought to outpatient's department of the hospital where children were examined and diagnosed by pediatrician and adults were examined by the pulmonologist. Results: There were 125 children and 1365 household members. Prevalence of active TB in adult household contacts was 8.1 percent and among children was 5.7 percent. Mother, father, grand parents or siblings were the source of disease spread in children. Family history of TB was present in 95 percent (pulmonary 78 percent, extra-pulmonary 22 percent). Conclusion: Tuberculosis in children is mostly spreading from household member hence deeply required to undertake active contact tracing in each new case that is diagnosed or being treated. Policy message: National and Provincial TB programs should advocate and undertake active screening of all household contacts of all TB cases. (author)

    Objective: We examined clinical and imaging findings of suspected idiopathic normal pressure hydrocephalus (iNPH) in relation to vascular risk factors and white matter lesions (WMLs), using a nested case-control design in a representative, population-based sample. Methods: From a population-based sample, 1,235 persons aged 70 years or older were examined with CT of the brain between 1986 and 2000. We identified 55 persons with hydrocephalic ventricular enlargement, i.e., radiologic findings consistent with iNPH. Among these, 26 had clinical signs that fulfilled international guideline criteria for probable iNPH. These cases were labeled suspected iNPH. Each case was matched to 5 controls from the same sample, based on age, sex, and study cohort. Data on risk factors were obtained from clinical examinations and the Swedish Hospital Discharge Register. History of hypertension, diabetes mellitus (DM), smoking, overweight, history of coronary artery disease, stroke/TIA, and WMLs on CT were examined. Risk factors associated with iNPH with a p value <0.1 in χ2 tests were included in conditional logistic regression models. Results: In the regression analyses, suspected iNPH was related to moderate to severe WMLs (odds ratio [OR] 5.2; 95% confidence interval [CI]: 1.5–17.6), while hydrocephalic ventricular enlargement was related to hypertension (OR 2.7; 95% CI: 1.1–6.8), moderate to severe WMLs (OR 6.5; 95% CI: 2.1–20.3), and DM (OR 4.3; 95% CI: 1.1–16.3). Conclusions: Hypertension, WMLs, and DM were related to clinical and imaging features of iNPH, suggesting that vascular mechanisms are involved in the pathophysiology. These findings might have implications for understanding disease mechanisms in iNPH and possibly prevention. PMID:26773072

    Full Text Available Case History: We are presenting a case of seven year old male with disseminated tuberculosis and infection with Strongyloides stercoralis (S.stercoralis The patient had severe hypoproteinemia and anasarca. S.stercoralis is a helminthic infection. Infection is acquired by walking bare foot on contaminated soil. After infection the filariform larvae invade the venous circulation and reach the intestine via respiratory system. Hyperinfection with this parasite leads to steatorrhea, oedema of duodenum, protein losing enteropathy,especially in immunocompromised individual. The patient had disseminated tuberculosis leading to decreased immunity which made the patient susceptible to hyperinfection with strongyloides. The patient responded dramatically to Ivermectin and anti tuberculartreatment. Timely intervention with appropriate drugs may prove to be lifesaving in such condition.

    Full Text Available Abstract The criteria for the diagnosis of HNPCC established by the ICG-HNPCC are very restrictive as they do not allow for the diagnosis of a large number of "suspected HNPCC" cases - these are families which do no fulfill the strict diagnostic "Amsterdam criteria", but do present with several pedigree and clinical features characteristic for HNPCC. Several series of families suspected of harboring germline mutations in DNA mismatch repair genes have been studied for germline changes in DNA mismatch repair genes and a mutation rate of somewhere between 8-60% was found. Therefore a subgroup of members of the ICG-HNPCC has been working on pedigree/clinical diagnostic criteria for suspected HNPCC. Materials and methods Part I The study was based on two series of colorectal cancer (CRC cases: 1 HNPCC - this group comprised 190 patients affected by CRC from randomly selected families which fulfilled the Amsterdam II criteria registered in Düsseldorf, Germany (102 cases of CRC, Denmark (18 CRCs, Leiden, Holland (23 CRCs and Szczecin, Poland (47 CRCs. 2 Consecutive CRCs - this group comprised 629 (78.0% of 806 individuals with CRC diagnosed in 1991-1997 in the city of Szczecin (ca. 400,000 of inhabitants, Poland. Nuclear pedigrees in both groups were compared for frequency of occurrence of clinical features, that have been shown to be associated with HNPCC. Part II 52 consecutive CRC cases from Szczecin, matching the criteria recognized in part I as appropriate for diagnosis of cases "suspected of HNPCC" were studied for the occurrence of germline hMSH2/hMLH1 constitutional mutations using "exon by exon" sequencing. Results The combination of features - i.e. the occurrence of an HNPCC associated cancer (CRC or cancer of the endometrium, small bowel or urinary tract in a 1st degree relative of a CRC patient; at least one of the patients being diagnosed under age of 50 - appeared to be strongly associated to HNPCC with an OR - 161.

    Because of signs of tuberculous lesions in old skeletons it can be stated with certainty that tuberculosis has occurred in the country shortly after the settlement. From that time and up to the seventeenth century, little or nothing is known about the occurrence of the disease. A few preserved descriptions of diseases and deaths indicate that tuberculosis has existed in the country before the advent of qualified physicians in 1760. On the basis of papers and reports from the first physicians and the first tuberculosis registers the opinions is set forth that the disease has been rare up to the latter part of the nineteenth century. During the two last decades of that century the disease began to spread more rapidly and increased steadily up to the turn of the century. Although reporting of the disease was started in the last decade of the nineteenth century the reporting was first ordered by law with the passage of the first tuberculosis Act in the year 1903. With this legislation official measures for tuberculosis control work really started in the country. The first sanatorium was built in 1910. In 1921 the tuberculosis Act was revised and since then practically all the expenses for the hospitalization and treatment of tuberculous cases has been defrayed by the state. In the year 1935 organized tuberculosis control work was begun and a special physician appointed to direct it. From then on systematic surveys were made, partly in health centers i.e. tuberculosis clinics, which were established in the main towns, and partly by means of transportable X ray units in outlying rural areas of the country. In 1939 the tuberculosis Act was again revised with special reference to the surveys and the activities of the tuberculosis clinics. This act is still in force. Some items of it are described. The procedure of the surveys and the methods of examination are described. The great majority of subjects were tuberculin tested and all positive reactors X rayed. Furthermore, X

    Tuberculosis (TB) is one of the major health problems in prisons. This study was done to assess the prevalence and determinants of active tuberculosis in Ethiopian prisons. A cross-sectional study was conducted from January 2013 to December 2013 in 13 zonal prisons. All incarcerated inmates underwent TB symptom screening according to WHO criteria. From identified TB-suspects two sputum samples were analyzed using smear microscopy and solid culture. A standardized questionnaire assessing TB risk factors was completed for each TB suspect. 765 (4.9%) TB suspects were identified among 15,495 inmates. 51 suspects were already on anti-TB treatment (6.67%) and 20 (2.8%) new culture-confirmed TB cases were identified in the study, resulting in an overall TB prevalence of 458.1/100,000 (95%CI: 350-560/100,000). Risk factors for active TB were alcohol consumption, contact with a TB case before incarceration and no window in prison cell. HIV prevalence was not different between TB suspects and active TB cases. Further, the TB burden in prisons increased with advancing distance from the capital Addis Ababa. The overall TB prevalence in Ethiopian prisons was high and extremely variable among different prisons. TB risk factors related to conditions of prison facilities and the impact of implemented TB control measures need to be further studied in order to improve TB control among inmates.

    Tuberculosis is endemic in Tunisia. Pulmonary tuberculosis is the most common presentation in our country. Cutaneous presentations are rare (1-2% of cases). The diagnosis of cutaneous tuberculosis (CT) is difficult. Histological and clinical presentations are polymorphous, many differential diagnoses are available, and it is difficult to isolate Mycobacterium. We had for aim to study the epidemiological and clinical features of CT in Tunisia, and to compare presentations before and after 1990. We conducted a retrospective study between January 1991 and December 2011, in which we included all cases of CT observed at the Infectious Diseases and Dermatology Units of the Tunis la Rabta Hospital. Hundred and thirty-seven patients were included, with a mean age of 43.8years; 72.3% were female patients. Hundred and fifty locations were observed, most of which on the head and neck. Scrofuloderma was the most frequent presentation, observed in 65% of cases. The diagnosis was confirmed by histology and/or microbiology in 75.8% of cases. The treatment was prescribed for a mean 11.3months, leading to full recovery in most cases. CT is still reported in Tunisia. The diagnosis relies mainly on histology. Controlling this mutilating tuberculosis requires a global control of this disease, and especially lymph node location, given the high rate of scrofuloderma. Copyright © 2013 Elsevier Masson SAS.

    To detect Mycobacterium tuberculosis (MTB) and rifampin resistance of the clinical specimens in children by Xpert MTB DNA and resistance to rifampicin(MTB/RIF) detection system, and evaluate the application value of this method in children with tuberculosis. Data of 109 children cases of clinically suspected tuberculosis were collected (including 46 gastric lavage aspirate, 19 sputum, 10 fine needle aspiration biopsy, 4 pus, 14 cerebrospinal fluid, 11 Serous membrance fluid, 1 marrow, 3 stool, 1 urine specimens)between April 2014 and March 2015. All specimens were detected by smear fluorescence staining microscopy, MGIT 960 BACTEC liquid culture, Xpert MTB/RIF assay and T-SPOT.TB test respectively. The sensitivity and specificity of Xpert MTB/RIF assay were analyzed in those clinical specimens. The sensitivity and specificity of the Xpert MTB/RIF assay for MTB detection in childhood tuberculosis clinical specimen were 28.6% and 87.5%. The sensitivity of 65 pulmonary tuberculosis(46 gastric lavage aspirate, 19 sputum) which included gastric lavage aspirates and sputum was 33.3% and 57.1%, the specificity of the two was 100.0%. In 44 extrapulmonary tuberculosis, the sensitivity of the pus and the puncture fluid was higher and approached 100.0%. The detection rate of the cerebrospinal fluid and serous cavity effusion was very low. The sensitivity was 100.0% in smear-positive and culture-positive samples and only 30.8% to 50.0% in smear-negative and culture-positive samples. The sensitivity and specificity of Xpert MTB/RIF assay to detect rifampin resistance were 100.0%. In clinical samples, the sensitivity of Xpert MTB/RIF assay was higher than that of smear fluorescence staining microscopy, but the difference was not statistically significant (χ(2)=0, P>0.05). The result was equivalent to that of MGIT 960 BACTEC liquid culture (28.6% vs. 27.3%, χ(2)=2.50, P>0.05), and far below that of T-SPOT.TB(28.6% vs 59.7%, χ(2)=13.92, Ptuberculosis, especially in serous

    This study aimed to determine the effect of an evidence-based clinical decision support (CDS) algorithm on the use and yield of CT pulmonary angiography (CTPA) and on outcomes of patients evaluated in the emergency department (ED) for suspected PE. The study included 1363 consecutive patients evaluated for suspected PE in an ED during 12 months before and 12 months after initiation of CDS use. Introduction of CDS was associated with decreased CTPA use (55% vs 49%; absolute difference (AD), 6.3%; 95% CI 1.0% to 11.6%; p=0.02). The use of CDS was associated with fewer symptomatic venous thromboembolic events during follow-up in patients with an initial negative diagnostic evaluation for PE (0.7% vs 3.2%; AD 2.5%; 95% CI 0.9% to 4.6%; p<0.01).

    Full Text Available OBJECTIVE To assess the increased diagnostic yield for pulmonary tuberculosis using bronchial washing cultures compared with sputum cultures. METHODS Study conducted with 61 adults in Lima, Peru, from January 2006 to December 2007. The yield of sputum cultures was compared with the yield of acid-fast bacilli smears and cultures of bronchial washing for diagnosing pulmonary tuberculosis in suspected cases of clinical tuberculosis with negative acid fast bacilli sputum smears. RESULTS Twenty seven (95%CI 32;58 of the cases were eventually diagnosed with smear-negative pulmonary tuberculosis. Bronchial washing samples detected 23 (95%CI 72;99 of the smear-negative pulmonary tuberculosis cases compared with 15 (95%CI 37;74 for sputum cultures (p = 0.02. The incremental diagnostic yield of acid fast bacilli smear and culture of bronchial washing specimens over sputum culture was 44% (95%CI 25;65. CONCLUSIONS In function of the epidemiological context and the resources available, bronchoscopy should be deployed as part of a comprehensive work up that optimizes smear-negative pulmonary tuberculosis diagnosis and minimizes risk and costs.

    Tuberculosis combined with brucellosis is a very rare condition. Overlapping clinical presentation and laboratory parameters of tuberculosis and brucellosis may lead to misdiagnosis or delayed diagnosis of the condition. The current study presents the case of a 45-year-old male with symptoms of lower back pain, non-tender swelling in the right flank, intermittent hyperpyrexia, sweating, body aches and numbness and weakness of right lower limb. A lumbar computed tomograph (CT) scan and magnetic resonance imaging indicated vertebral destruction and the formation of sequestra and thecal sac compression. Tuberculosis was suspected, but subsequent culture of blood and pus revealed the co-infection of Mycobacterium tuberculosis and Brucella melitensis . The patient was treated with antibiotics, CT-guided percutaneous drainage of the abscess and posterior approach decompression, debridement, instrumentation and fusion. Co-existence of spinal tuberculosis and brucellosis is rare and clinicians should strengthen the awareness of such conditions in similar patients. CT-guided percutaneous drainage is effective in the diagnosis and management of spinal tuberculosis with abscess.

    Consensus case definitions for childhood tuberculosis have been proposed by an international expert panel, aiming to standardize the reporting of cases in research focusing on the diagnosis of intrathoracic tuberculosis in children. These definitions are intended for tuberculosis diagnostic evaluation studies of symptomatic children with clinical suspicion of intrathoracic tuberculosis, and were not intended to predefine inclusion criteria into such studies. Feedback from researchers suggested that further clarification was required and that these case definitions could be further improved. Particular concerns were the perceived complexity and overlap of some case definitions, as well as the potential exclusion of children with acute onset of symptoms or less severe disease. The updated case definitions proposed here incorporate a number of key changes that aim to reduce complexity and improve research performance, while maintaining the original focus on symptomatic children suspected of having intrathoracic tuberculosis. The changes proposed should enhance harmonized classification for intrathoracic tuberculosis disease in children across studies, resulting in greater comparability and the much-needed ability to pool study results. © The Author 2015.

    Intestinal symptoms affect most AIDS patients at some point in their disease. The purpose of this study was to evaluate the use of CT in this setting. A total of 339 abdominal CT exams were reviewed for signs of intestinal disease. Abdominal CT scans of 45 patients with intestinal symptoms were compared with colonoscopy and histologic data. The CT results were correlated with CD4{sup +} T-lymphocyte counts and patient survival. More than 14 % of all abdominal CT exams displayed signs of enteric disease. Of the 45 patients studied with both CT and colonoscopy, 35 (78 %) had signs of intestinal disease by CT. Of these 35 patients, colonoscopic signs of an intestinal lesion were found in 29 and histologic proof of disease was established in 30 cases. Colonoscopy and histology detected 8 lesions missed by CT. There were 14 cases of unspecific colitis, 15 cases of cytomegalovirus (CMV) colitis, and 4 cases of enteric tuberculosis as per biopsy. Five patients presented with Kaposi`s sarcoma and 1 with a non-Hodgkin`s lymphoma. Neither colonoscopic nor CT signs of intestinal disease did reliably distinguish between histologic subgroups. Specifically, CMV colitis could not be distinguished from unspecific colitis. CD4{sup +} T-lymphocyte counts for histologic subgroups were not significantly different, either. No colonoscopic or histologic feature predicted survival, whereas low CD4 counts and ascites on CT indicated a poor prognosis. Whereas CT detects signs of intestinal disease in most AIDS patients, these signs remain largely unspecific. Colonoscopy and biopsies provide no consistently valid standard with which to compare CT because of controversial sensitivity and specificity of these methods. The CT technique detects small bowel as well as extraintestinal disease. Therefore, CT is an important diagnostic modality in abdominal disease of immunocompromised patients. (orig.)

    BACKGROUND: Little is known about the prevalence of pulmonary tuberculosis (TB) in low income countries. We conducted a cross sectional survey for pulmonary TB and TB symptoms in Bissau, Guinea-Bissau, in an urban cohort with known HIV prevalence. TB surveillance in the area is routinely based...... on passive case finding. METHODS: Two cohorts were selected based on a previous HIV survey, but only 52.5% of those enrolled in the adult cohort had participated in the HIV survey. One cohort included all adults living in 384 randomly selected houses; in this cohort 8% (135/1687) were HIV infected. The other...... included individuals 50 years or older from all other houses in the study area; of these 11% (62/571) were HIV infected. Symptom screening was done through household visits using a standardised questionnaire. TB suspects were investigated with sputum smear microscopy and X-ray. RESULTS: In the adult cohort...

    A 12-year-old girl presented with prolonged fever with no obvious focus on either history or clinical examination. High-resolution computerized tomography of the chest revealed the ‘tree-in-bud’ sign in the right lung and necrotic mediastinal lymph nodes. Barium meal showed multiple ileal strictures. The child was treated with anti-tuberculous therapy for six months. At follow-up six months later, the child had gained weight and had no signs of intestinal obstruction. Tuberculosis is a common cause of fever of undetermined origin and should be investigated for especially in countries with a high prevalence. PMID:25478420

    The chest radiographs of 95 patients with the new diagnosis of atypical turberculosis were reviewed to determine if any significant differences between atypical tuberculosis and that caused by Mycobacterium tuberculosis could be discerned. Findings included upper lobe involvement in B4 of the 95 patients and cavities in 76, with nearly equal groups having no, moderate, or extensive surrounding alveolar disease. Nodules were common; in six patients a nodule was the sole manifestation of disease. Adenopathy was seen in 12 of the 95 patients, atlectasis in 45, pleural thickening in 90, and effusions in three. These radiographic findings did not allow the radiographic differentiation of atypical tuberculosis from Mycobacterium tuberculosis infection

    2000-04-01

    Tuberculosis is a curable infective disease which can mimic a malignant tumor. We report on a young woman who presented with abdominal fullness, body weight loss, and microcytic anemia. A pelvic mass and peritoneal lesions were found. The serum CA125 level was high. The initial gynecologic echo and abdominal CT scan revealed bilateral ovarian mass with peritoneal lesions, and malignancy was highly suspected. Diagnostic laparoscopy was performed, and peritoneal tuberculosis was pathologically proven. Combination anti-tuberculosis therapy was prescribed for one year. She was followed up in the outpatient clinic regularly with symptom improvement, body weigh gain, and improvement of anemia. We suggest that in cases of a pelvic mass and peritoneal lesions, with elevation of the serum CA125 level, tuberculosis should always be kept on the list of differential diagnoses. A tissue diagnosis should always be obtained before treatment, regardless of initial image study and laboratory findings.

    This report describes a case of Tsukamurella pneumonia in a 24-year-old immunocompetent woman. The patient was diagnosed as having pulmonary tuberculosis and was treated for nearly 9 months. The correct diagnosis was suspected only when the results of mycobacteria nucleic acid amplification tests on cultural colonies were negative. Tsukamurella was identified from the patient's sputum and bronchoalveolar lavage fluid by using 16S rRNA sequence analysis. Here, the clinical presentation, diagnosis, and treatment strategies of Tsukamurella pneumonia are discussed, along with a literature review. Tsukamurella pneumonia may be highly underdiagnosed owing to its similarity with pulmonary tuberculosis and the habitual thinking of doctors in countries with a high tuberculosis burden. Tsukamurella should be carefully considered in the etiology of tuberculosis-like lung diseases.

    Background Diagnosing tuberculosis in children is challenging because specimens are difficult to obtain and contain low tuberculosis concentrations, especially with HIV-coinfection. Few studies included well-controls so test specificities are poorly defined. We studied tuberculosis diagnosis in 525 children with and without HIV-infection. Methods and Findings ‘Cases’ were children with suspected pulmonary tuberculosis (n = 209 HIV-negative; n = 81 HIV-positive) and asymptomatic ‘well-control’ children (n = 200 HIV-negative; n = 35 HIV-positive). Specimens (n = 2422) were gastric aspirates, nasopharyngeal aspirates and stools analyzed by a total of 9688 tests. All specimens were tested with an in-house hemi-nested IS6110 PCR that took 0.2) for HIV-positive versus HIV-negative cases. All specimens were also tested with auramine acid-fast microscopy, microscopic-observation drug-susceptibility (MODS) liquid culture, and Lowenstein-Jensen solid culture that took ≤6 weeks and had 100% specificity (all 2112 tests on 704 specimens from 235 well-controls were negative). Microscopy-positivity was rare (0.21%, 5/2422 specimens) and all microscopy-positive specimens were culture-positive. Culture-positivity was less frequent (P≤0.01) in HIV-infection: 1.2% (1/81) HIV-positive cases versus 11% (22/209) HIV-negative cases; caused by 0.42% (2/481) versus 4.7% (58/1235) of their specimens, respectively. Conclusions In HIV-positive children with suspected tuberculosis, diagnostic yield was so low that 1458 microscopy and culture tests were done per case confirmed and even in children with culture-proven tuberculosis most tests and specimens were false-negative; whereas PCR was so prone to false-positives that PCR-positivity was as likely in specimens from well-controls as suspected-tuberculosis cases. This demonstrates the importance of control participants in diagnostic test evaluation and that even extensive laboratory testing only rarely contributed to the care of

    Child tuberculosis contact screening and management can enhance case finding and prevent tuberculosis disease. It is universally recommended but rarely implemented in tuberculosis-endemic settings. The World Health Organization (WHO)-recommended symptom-based screening approach could improve implementation but has not been prospectively evaluated. We conducted a cohort study of children who were close contacts of pulmonary tuberculosis patients in Indonesia from August 2010 to December 2012. We performed clinical assessment, tuberculin skin test, and chest radiography in all eligible children irrespective of symptoms at baseline. Mycobacterial culture and Xpert MTB/RIF assay were performed on sputum from children with persistent symptoms of suspected tuberculosis. Children were managed according to WHO guidelines and were prospectively followed for 12 months. A total of 269 child contacts of 140 index cases were evaluated. At baseline, 21 (8%) children had tuberculosis diagnosed clinically; an additional 102 (38%) had evidence of infection without disease. Of children with any tuberculosis-related symptoms at baseline, 21% had tuberculosis diagnosed compared with none of the asymptomatic children (P children who did not receive IPT. Symptom-based screening is an effective and simple approach to child tuberculosis contact management that can be implemented at the primary healthcare level. © The Author 2014.

    Full Text Available Background: In developing countries like India, where poverty, malnutrition and overcrowding prevail, tuberculosis continues to be one of the important causes of morbidity, mortality and loss of working man hours. Abdominal tuberculosis (TB can affect the gastrointestinal tract, the peritoneum, lymph nodes of the small bowel mesentery or the solid viscera (e.g. liver, spleen, pancreas etc Patient of abdominal Koch’s can present as those with a chronic undulating course and those with an acute or subacute abdominal catastrophe. In emergency the patient may present with various presentations like stricture causing obstruction or with perforation and require a different management from those routine such cases Aim and Objective: To study the varied presentation of patients with Abdominal Tuberculosis as acute surgical abdomen presenting in emergency setting to those with a subacute course. To evaluate the line of management whether operative or conservative, the operative details, post operative course and the final outcome of the disease. To study the incidence of HIV positivity in patients with abdominal tuberculosis. Methods and material: The study was designed as a prospective observational study conducted during a study period between June 2006 and June 2008 in a tertiary care centre in Mumbai. All patients with a clinical suspicion of abdominal tuberculosis were included in the study with confirmation on histopathological examination. Patient’s written informed valid consent was taken after explaining the nature of study. Result and Conclusion: Age group commonly affected was between 21-30 years with male predominance. Amongst the various complications of abdominal tuberculosis intestinal obstruction was the most common mainly due to stricture and less commonly due to hyperplastic ileocaecal mass. Next common complication observed was free perforation of the intestine which occurs at a site proximal to a tight stricture. All patients were

    Pyridoxine is always simultaneously administered orally with isoniazid for tuberculosis patients in the clinic to prevent or treat the nervous system side effects induced by isoniazid. So the aim of this research was to investigate the effects of pyridoxine on the intestinal absorption and pharmacokinetics of isoniazid. The intestinal absorption of isoniazid with or without pyridoxine was investigated by the rat single-pass intestinal perfusion model in situ, and a high-performance liquid chromatographic method was applied to study the pharmacokinetics of isoniazid with or without pyridoxine. The results suggested that the intestinal apparent permeability (P app) and intestinal absorption rate constant (K a) for isoniazid (30 μg/ml) were decreased by 43.7 and 36.4 %, respectively, by co-perfused pyridoxine (40 μg/ml). In vivo, the effect of pyridoxine on isoniazid pharmacokinetic correlated with the doses of pyridoxine. The blood concentrations of isoniazid at the absorption phase were affected by co-administered pyridoxine, but the AUC and C max of isoniazid were not greatly affected by pyridoxine as expected from the inhibition by pyridoxine of the intestinal absorption of isoniazid, which could be caused by its rapid absorption phase. Therefore, although the intestinal absorption of isoniazid could be significantly inhibited by pyridoxine, the pharmacokinetics of isoniazid oral administration was not greatly affected by the decreased intestinal absorption of isoniazid due to its rapid absorption.

    The treatment of drug-sensitive tuberculosis consists of 2 months of isoniazid, rifampin, pyrazinamide and ethambutol, followed by 4 months of isoniazid and rifampin. These drugs are well tolerated and cure rate are above 95 %. In contrast the treatment of drug-resistent tuberculosis is difficult, mostly due to side effects of the drugs used under these circumstances. Therefore, any treatment of drug-resistant tuberculosis has to be done by experts.

    Full Text Available Tuberculosis has been reported in almost all bones of body. The great trochanter tuberculosis (GTT installation is insidious and clinical symptoms are often vague with moderate painful swelling and stiffness. GTT is about 0,2 to 2% of all osteo-articular tuberculosis, occurring most commonly by hematogenous seeding secondary to primary focus elsewhere, more commonly in the lungs. Isolated GTT is unusual and thus its awareness is slow and diagnosis is often delayed.

    Tuberculosis in childhood is clinically challenging, but it is a preventable and treatable disease. Risk factors depend on age and immunity status. The most common form of pediatric tuberculosis is pulmonary disease, which comprises more than half of the cases. Other forms make up the extrapulmonary tuberculosis that involves infection of the lymph nodes, central nervous system, gastrointestinal system, hepatobiliary tree, and renal and musculoskeletal systems. Knowledge of the imaging characteristics of pediatric tuberculosis provides clues to diagnosis. This article aims to review the imaging characteristics of common sites for extrapulmonary tuberculous involvement in children.

    Wernery, U; Kinne, J

    2012-12-01

    Tuberculosis is a chronic, contagious, granulomatous disease caused by mycobacterial species belonging to the Mycobacterium tuberculosis complex. Camelids were not considered highly susceptible to tuberculosis, but in recent years increased numbers of cases have been experienced in some countries. In most of the cases, transmission probably occurs through contact with infected cattle or wildlife. None of the ante-mortem tests currently available can consistently provide accurate diagnosis of the infection in live camelids. Recently developed serological assays have the potential for rapid and accurate diagnosis of tuberculosis but still need to be validated.

    Full Text Available Data on genotypic diversity of Mycobacterium tuberculosis complex (MTBC is important to understand its epidemiology, human adaptation, clinical phenotypes, and drug resistance. This study aimed to characterize MTBC clinical isolates circulating in a predominantly pastoralist area in Ethiopia, a country where tuberculosis is the second leading cause of mortality. Culture of sputum samples collected from a total of 325 pulmonary TB suspects was done to isolate MTBC. Spoligotyping was used to characterize 105 isolates from culture positive slopes and the result was compared with an international database. Forty-four spoligotype patterns were observed to correspond to 35 shared-types (SITs containing 96 isolates and 9 orphan patterns; 27 SITs containing 83 isolates matched a preexisting shared-type in the database, whereas 8 SITs (n=13 isolates were newly created. A total of 19 SITs containing 80 isolates were clustered within this study (overall clustering of 76.19%. Three dominant lineages (T, CAS, and Manu accounted for 76.19% of the isolates. SIT149/T3-ETH was one of the two most dominant sublineages. Unlike previous reports, we show that Manu lineage strains not only constitute a dominant lineage, but are also associated with HIV infection in Afar region of Ethiopia. The high level of clustering suggests the presence of recent transmission that should be further studied using additional genotyping markers.

    1995-01-01

    We used computerized tomography (CT) in the study of eight patients with macronodular splenic tuberculosis prior to the microbiological diagnosis. These patients underwent additional CT controls during and after tuberculostatic therapy. All the patients studed presented the acquired immunodeficiency syndrome (AIDS). Splenomegaly and numerosous round, hypodense lesions that showed no contrast uptake were found in all the subjects. Only three patients presented evidence of tuberculosis in plain radiography and/or chest X-ray. Two patients presented abdominal lymph nodes. None of them showed evidence of hepatic lesions or ascites. follow-up CT scans revealed a progressive reduction of the lesions, which eventually disappeared completely, and splenomegaly was considerably reduced. Anthough it is uncommon, we should suspect splenic involvement in tuberculosis if the clinical and radiological contexts are appropriate. CT provides excellent monitoring of the efficacy of treatment in these patients. 17 refs

    We report a case of a pregnant 21-year-old woman with pulmonary tuberculosis in which magnetic resonance imaging of the lung was used to assess the extent and characteristics of the pathological changes. Although the lung has been mostly ignored in magnetic resonance imaging for many decades, today technical development enables detailed examinations of the lung. The technique is now entering the clinical arena and its indications are increasing. Magnetic resonance imaging of the lung is not only an alternative method without radiation exposure, it can provide additional information in pulmonary imaging compared to other modalities including computed tomography. We describe a successful application of magnetic resonance imaging of the lung and the imaging appearance of post-primary tuberculosis. This case report indicates that magnetic resonance imaging of the lung can potentially be the first choice imaging technique in pregnant women with suspected pulmonary tuberculosis.

    Full Text Available Objectives: To describe clinical and epidemiological characteristics of inpatients with tuberculosis (TB and to assess the knowledge of health personnel on fundamental concepts about TB and control measures for pulmonary tuberculosis in a hospital environment. Methods: The study was conducted in a tertiary hospital in Fortaleza-CE and involved patients admitted with TB and health professionals responsible for assistance. A first phase was characterized by a retrospective study of medical records of patients admitted with suspected TB. In a second stage, a cross-sectional study with application of a structured questionnaire assessed the knowledge of health personnel on TB control measures in a hospital environment. Results: Sixty-seven patients admitted with suspected TB had their medical records assessed. Among the confirmed cases, the most frequent clinical form was pulmonary (81.3%. Out of 55 patients admitted with suspected pulmonary tuberculosis, only 29 (52.7% were admitted in a respiratory isolation bed. Twenty-six patients with suspected pulmonary tuberculosis on admission stayed a total of 148 days out of a respiratory isolation bed (average 4.1 days / patient. The knowledge of 159 health professionals about TB was assessed. Regarding the transmission of TB, 107 (67.2% were unaware of airborne transmission and 109 (68.5% ignored the clinical forms that require respiratory isolation. Conclusions: Pulmonary tuberculosis is the most frequent clinical form among inpatients in a tertiary hospital in Fortaleza-CE. Considerable fraction of health personnel doesn’t know key concepts related to tuberculosis and essential for the proper and safe care.

    Background Exome sequencing is a promising tool for gene mapping in Mendelian disorders. We utilized this technique in an attempt to identify novel genes underlying monogenic dyslipidemias. Methods and Results We performed exome sequencing on 213 selected family members from 41 kindreds with suspected Mendelian inheritance of extreme levels of low-density lipoprotein (LDL) cholesterol (after candidate gene sequencing excluded known genetic causes for high LDL cholesterol families) or high-density lipoprotein (HDL) cholesterol. We used standard analytic approaches to identify candidate variants and also assigned a polygenic score to each individual in order to account for their burden of common genetic variants known to influence lipid levels. In nine families, we identified likely pathogenic variants in known lipid genes (ABCA1, APOB, APOE, LDLR, LIPA, and PCSK9); however, we were unable to identify obvious genetic etiologies in the remaining 32 families despite follow-up analyses. We identified three factors that limited novel gene discovery: (1) imperfect sequencing coverage across the exome hid potentially causal variants; (2) large numbers of shared rare alleles within families obfuscated causal variant identification; and (3) individuals from 15% of families carried a significant burden of common lipid-related alleles, suggesting complex inheritance can masquerade as monogenic disease. Conclusions We identified the genetic basis of disease in nine of 41 families; however, none of these represented novel gene discoveries. Our results highlight the promise and limitations of exome sequencing as a discovery technique in suspected monogenic dyslipidemias. Considering the confounders identified may inform the design of future exome sequencing studies. PMID:25632026

    Four cases of aorto-enteric fistula are reported. The two primary types occurred after rupture of an aneurysm of the abdominal aorta into the duodenum and as a consequence of tumor infiltration of both the aorta and the intestinal wall in a woman with metastatic ovarian cancer. The two secondary types developed as a late complication of reconstructive surgery of the abdominal aorta. The condition was diagnosed or suspected on the basis of endoscopic findings in two cases. The pathogenetic role of graft infection in the development of secondary aorto-enteric fistula is emphasized. The generally poor prognosis can be considerably improved if prompt resection of the graft is combined with axillo-bifemoral anastomosis.

    Full Text Available Early, efficient and inexpensive methods for the detection of pulmonary tuberculosis are urgently needed for effective patient management as well as to interrupt transmission. These methods to detect M. tuberculosis in a timely and affordable way are not yet widely available in resource-limited settings. In a developing-country setting, we prospectively evaluated two methods for culturing and detecting M. tuberculosis in sputum. Sputum samples were cultured in liquid assay (micro broth culture in microplate wells and growth was detected by microscopic observation, or in Löwenstein-Jensen (LJ solid media where growth was detected by visual inspection for colonies. Sputum samples were collected from 321 tuberculosis (TB suspects attending Bugando Medical Centre, in Mwanza, Tanzania, and were cultured in parallel. Pulmonary tuberculosis cases were diagnosed using the American Thoracic Society diagnostic standards. There were a total of 200 (62.3% pulmonary tuberculosis cases. Liquid assay with microscopic detection detected a significantly higher proportion of cases than LJ solid culture: 89.0% (95% confidence interval [CI], 84.7% to 93.3% versus 77.0% (95% CI, 71.2% to 82.8% (p = 0.0007. The median turn around time to diagnose tuberculosis was significantly shorter for micro broth culture than for the LJ solid culture, 9 days (interquartile range [IQR] 7-13, versus 21 days (IQR 14-28 (p<0.0001. The cost for micro broth culture (labor inclusive in our study was US $4.56 per sample, versus US $11.35 per sample for the LJ solid culture. The liquid assay (micro broth culture is an early, feasible, and inexpensive method for detection of pulmonary tuberculosis in resource limited settings.

    In the European Union tuberculosis prevalence-rates are among the lowest in the world. The prevalence of active tuberculosis in migrant populations has to be analyzed to get valid data on the risk of tuberculosis and for the decision of screening activities. Therefore, we prospectively quantified the risk of active tuberculosis among asylum seekers at time of arrival. Investigation was performed as regular part of the admission screenings for people arriving at Friedland, Germany, a primary major receiving center during one year. In 11.773 newly arrived asylum seekers 16 X-ray investigations gave the suspicion of active tuberculosis, thereof 11 cases could be verified by culture, thereof 9 cases were classified as microscopically positive. These data translate into rates of 136 per 100.000 suspected cases, 93 per 100.000 verified cases, and finally 76 per 100.000 infectious cases, respectively. Prevalence was higher in asylum seekers coming from Eritrea and Russia compared to the main origins of current migration Syria, Afghanistan, Iraq, Iran, and Lebanon. One case of MDR-tuberculosis could be detected in a migrant from Russia. Prevalence rates of tuberculosis in newly arrived asylum seekers are higher than in native European populations. Rates seem to reflect the prevalence in the home countries. X-ray investigation during first examination may help identifying people needing further tests for detecting infectious tuberculosis and therefore may prevent transmission. However due to the low prevalence rates screening procedures have to be reviewed. Copyright © 2016 Elsevier GmbH. All rights reserved.

    In the present study, IS6110 loop mediated isothermal amplification (LAMP) assay was modified using dUTP-UNG (uracil-DNA N-glycosylase) strategy to prevent carryover contamination, and was evaluated using clinical specimens. The clinical specimens were collected from 236 suspected patients of pulmonary tuberculosis and 315 specimens of suspected patients of extra pulmonary tuberculosis. DNA was extracted from specimens and used as template for nucleic acid amplification. The results were evaluated with culture method as gold standard. Modified IS6110 LAMP assay showed high sensitivity (94.4%) and specificity (97.2%) in specimens collected from suspected pulmonary tuberculosis patients. Sensitivity was comparatively less (86.67%) in extra pulmonary specimens while specificity was 94.04%. In conclusion, IS6110 LAMP assay was modified to prevent carry over contamination and it was validated to be rapid, sensitive and specific method with prospective application in resource-limited settings.

    Full Text Available This report describes 6 HIV-negative patients including 5 children with scrofuloderma and an adult with lupus vulgaris, out of a total of 303 cases of cutaneous tuberculosis seen during a 4½-year period, who showed a positive tuberculin test and granulomatous histopathology, but failed to respond to first-line antitubercular therapy. They were suspected to have multidrug-resistant infection as no other cause could be ascertained. Tissue aspirate or biopsy was sent for histopathology and culture. Mycobacterium tuberculosis was isolated from the aspirate in three patients and sputum in one with associated pulmonary tuberculosis. Drug susceptibility tests showed that all isolates were resistant to rifampicin and isoniazid, and one each additionally to streptomycin and ethambutol, respectively. In two, culture was unsuccessful. All were administered second-line antitubercular drugs. Clinical improvement was appreciable within 2 months as weight gain, and regression of ulcers, swellings and plaques. Two completed the recommended 24 months of therapy. Multidrug-resistant cutaneous tuberculosis should be suspected in patients with no response to first-line drugs, with clinical deterioration, and where other causes of treatment failure are not forthcoming. Owing to poor isolation rates on culture and low sensitivity of molecular tests, in such cases, a trial of second-line anti-tubercular drugs may be justified for a reasonable period of 2 months. Where facilities permit, culture and drug sensitivity tests should be done before starting treatment. Culture positivity is better from aspirated material.

    Tuberculosis (TB) remains an important infection in women globally. It is responsible for 700 000 deaths annually and is a major contributor to maternal mortality. Mycobacterium tuberculosis/HIV co-infection is common in areas of high HIV prevalence, and may be associated with significant perinatal and maternal morbidity. Improved diagnosis and treatment of TB in pregnant women are important interventions for both maternal and child health. Controlling TB in pregnancy in high-prevalence areas requires a range of interventions, including active TB screening in pregnant women, TB preventative therapy for HIV-infected pregnant women, treatment of active TB and linking mothers and children to TB care services. © 2010 The Authors Journal compilation © RCOG 2010 BJOG An International Journal of Obstetrics and Gynaecology.

  20. Targeting phenotypically tolerant Mycobacterium tuberculosis

    Gold, Ben; Nathan, Carl

    2016-01-01

    While the immune system is credited with averting tuberculosis in billions of individuals exposed to Mycobacterium tuberculosis, the immune system is also culpable for tempering the ability of antibiotics to deliver swift and durable cure of disease. In individuals afflicted with tuberculosis, host immunity produces diverse microenvironmental niches that support suboptimal growth, or complete growth arrest, of M. tuberculosis. The physiological state of nonreplication in bacteria is associated with phenotypic drug tolerance. Many of these host microenvironments, when modeled in vitro by carbon starvation, complete nutrient starvation, stationary phase, acidic pH, reactive nitrogen intermediates, hypoxia, biofilms, and withholding streptomycin from the streptomycin-addicted strain SS18b, render M. tuberculosis profoundly tolerant to many of the antibiotics that are given to tuberculosis patients in a clinical setting. Targeting nonreplicating persisters is anticipated to reduce the duration of antibiotic treatment and rate of post-treatment relapse. Some promising drugs to treat tuberculosis, such as rifampicin and bedaquiline, only kill nonreplicating M. tuberculosis in vitro at concentrations far greater than their minimal inhibitory concentrations against replicating bacilli. There is an urgent demand to identify which of the currently used antibiotics, and which of the molecules in academic and corporate screening collections, have potent bactericidal action on nonreplicating M. tuberculosis. With this goal, we review methods of high throughput screening to target nonreplicating M. tuberculosis and methods to progress candidate molecules. A classification based on structures and putative targets of molecules that have been reported to kill nonreplicating M. tuberculosis revealed a rich diversity in pharmacophores. However, few of these compounds were tested under conditions that would exclude the impact of adsorbed compound acting during the recovery phase of

    The incidence of tuberculosis worldwide is declining. However, in Western countries this decline is slower due to the impact of immigration. Tuberculosis in the immigrant population is related to health status in the country of origin and with overcrowding and poverty conditions in the host country. Immigrants with tuberculosis are younger, have a higher prevalence of extrapulmonary forms, greater proportion of drug resistance and higher treatment default rates than those of natives. New molecular techniques not only reduce diagnostic delay time but also allow the rapid identification of resistances and improve knowledge of transmission patterns. It is necessary to implement measures to improve treatment compliance in this population group like facilitating access to health card, the use of fixed-dose combination drugs, the participation of cultural mediators and community health workers and gratuity of drugs.

    Bovine tuberculosis, caused by Mycobacterium bovis, is a pathogen of growing concern in free-ranging wildlife in Africa, but little is known about the disease in Tanzanian wildlife. Here, we report the infection status of Mycobacterium bovis in a range of wildlife species sampled from protected areas in northern Tanzania. M. bovis was isolated from 11.1% (2/18) migratory wildebeest (Connochaetes taurinus) and 11.1% (1/9) topi (Damaliscus lunatus) sampled systematically in 2000 during a meat cropping program in the Serengeti ecosystem, and from one wildebeest and one lesser kudu (Tragelaphus imberbis) killed by sport hunters adjacent to Tarangire National Park. A tuberculosis antibody enzyme immunoassay (EIA) was used to screen serum samples collected from 184 Serengeti lions (Panthera leo) and 19 lions from Ngorongoro Crater sampled between 1985 and 2000. Samples from 212 ungulates collected throughout the protected area network between 1998 and 2001 also were tested by EIA. Serological assays detected antibodies to M. bovis in 4% of Serengeti lions; one positive lion was sampled in 1984. Antibodies were detected in one of 17 (6%) buffalo (Syncerus caffer) in Tarangire and one of 41 (2%) wildebeest in the Serengeti. This study confirms for the first time the presence of bovine tuberculosis in wildlife of northern Tanzania, but further investigation is required to assess the impact on wildlife populations and the role of different wildlife species in maintenance and transmission.

X-ray of chest (postero-anterior view showed multiple opacities with erosion of right 2nd and left 6th ribs. CT-scan of thorax and CT-guided FNAC con-firmed the diagnosis of tuberculosis of ribs. Even after 5-months of treatment with four first line drugs, the patient developed a cold abscess at the back. Mycobacterial culture and drug sensitivity of material aspirated by Radiometric method from the cold abscess showed growth of Mycobacterium tuberculosis, and those bacilli were resistant to both isoniazide and rifampicin. The patient did not have anti-tubercu-lar medication in the past, and that established the diagnosis of primary multidrug resistant tuberculosis of ribs. Patient was treated successfully with 2nd line drugs at the cost of moderate degree of hearing loss. After one and half years of treatment X-ray of chest (PA view showed complete healing of rib erosions with new bone formation.

    Full Text Available Endoscopic examination of the gastrointestinal (GI tract plays a very important role in the diagnosis and follow-up of patients with Crohn's disease (CD and intestinal tuberculosis (TB. The clinical, morphological, and histological features of GI TB and CD are so similar that it becomes difficult to differentiate between these two entities. In geographical regions such as India where both GI TB and CD are prevalent, differential diagnosis between the two is challenging. While there is a lot of similarities between these two disorders, these two can be differentiated from each other with a combination of clinical, endoscopic, histological, radiological, and endoscopic features. The observation of the characteristic lesions at endoscopic examination and the extent of involvement in CD and intestinal TB is an important step in differentiation between these two disorders. While the most important endoscopic characteristics such as involvement of left side of the colon and presence of longitudinal ulcerations and cobblestoning support a diagnosis of CD, predominant involvement of ileocecal region and transverse ulcers support the diagnosis of intestinal TB. In this review, we have described the usefulness and limitations of endoscopic modalities in the diagnosis and differentiation of intestinal TB and CD.

    A case of intestinal anisakidosis in a 42-year-old man in Japan is presented. His chief complaint was an acute onset of severe abdominal pain. Approximately 12 hours before the onset of this symptom, he had eaten sliced raw mackerel ("sashimi"). Upper endoscopy was unremarkable. At exploratory laparotomy, an edematous, diffusely thickened segment of jejunum was observed, which was resected. The postoperative course was uneventful. The segment of small intestine showed a granular indurated area on the mucosal surface, and microscopically, a helminthic larva penetrating the intestinal wall, which was surrounded by a cuff of numerous neutrophils and eosinophils, as well as diffuse acute serositis. A cross section of the larva revealed the internal structures, pathognomonic of Anisakis simplex. Although anisakidosis is rare in the United States, with the increasing popularity of Japanese cuisine, the incidence is expected to increase, and pathologists should be familiar with this disease.

  6. Intestinal failure: a review

    2018-01-01

    Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients (carbohydrate, protein, and fat), micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. Acute IF (types 1 and 2) is the initial phase of the illness and may last for weeks to a few months, and chronic IF (type 3) from months to years. The challenge of caring for patients with IF is not merely the management of the underlying condition leading to IF or the correct provision of appropriate nutrition or both but also the prevention of complications, whether thromboembolic phenomenon (for example, venous occlusion), central venous catheter-related bloodstream infection, IF-associated liver disease, or metabolic bone disease. This review looks at recent questions regarding chronic IF (type 3), its diagnosis and management, the role of the multidisciplinary team, and novel therapies, including hormonal treatment for short bowel syndrome but also surgical options for intestinal lengthening and intestinal transplant.

    The routine method of contrast matter passage applied to 850 patients with different gastrointestinal diseases proved inefficient to detect any small-intestinal diverticuli. The following modiffications of the method have been tested in order to improve the diagnostic possibilities of the X-ray: study at short intervals, assisted passage, enteroclysm, pharmacodynamic impact, retrograde filling of the ileum by irrigoscopy. Twelve diverticuli of the small-intestinal loops were identified: 5 Meckel's diverticuli, 2 solitary of which one of the therminal ileum, 2 double diverticuli and 1 multiple diverticulosis of the jejunum. The results show that the short interval X-ray examination of the small intestines is the method of choice for identifying local changes in them. The solitary diverticuli are not casuistic scarcity, its occurrence is about 0.5% at purposeful X-ray investigation. The assisted passage method is proposed as a method of choice for detection of the Meckel's diverticulum. 5 figs., 3 tabs. 18 refs

    1992-01-01

    Chronic intestinal pseudoobstruction syndrome is a rare clinical condition in which impaired intestinal peristalsis causes recurrent symptoms of bowel obstruction in the absence of a mechanical occlusion. This syndrome may involve variable segments of small or large bowel, and may be associated with urinary bladder retention. This study included 6 children(3 boys and 3 girls) of chronic intestinal obstruction. Four were symptomatic at birth and two were of the ages of one month and one year. All had abdominal distension and deflection difficulty. Five had urinary bladder distension. Despite parenteral nutrition and surgical intervention(ileostomy or colostomy), bowel obstruction persisted and four patients expired from sepses within one year. All had gaseous distension of small and large bowel on abdominal films. In small bowel series, consistent findings were variable degree of dilatation, decreased peristalsis(prolonged transit time) and microcolon or microrectum. This disease entity must be differentiated from congenital megacolon, ileal atresia and megacystis syndrome

    2016-06-01

    Small intestinal infections are extremely common worldwide. They may be bacterial, viral, or parasitic in etiology. Most are foodborne or waterborne, with specific etiologies differing by region and with diverse pathophysiologies. Very young, very old, and immune-deficient individuals are the most vulnerable to morbidity or mortality from small intestinal infections. There have been significant advances in diagnostic sophistication with the development and early application of molecular diagnostic assays, though these tests have not become mainstream. The lack of rapid diagnoses combined with the self-limited nature of small intestinal infections has hampered the development of specific and effective treatments other than oral rehydration. Antibiotics are not indicated in the absence of an etiologic diagnosis, and not at all in the case of some infections.

    Objective. To review imaging studies of isolated involvement of the sacrum due to tuberculosis and determine the role of imaging in the diagnosis and management of these patients.Design and patients. A retrospective analysis of 15 cases of isolated sacral tuberculosis imaged with MR imaging was performed. The CT images were also reviewed where available, and the various lesion characteristics were identified. We also reviewed the medical records in an attempt to determine the impact of the imaging studies on the management of these patients.Results. Fifteen patients (5 male, 10 female) presented with symptoms of 3-15 months' duration. Chronic localized backache with muscle spasm was the commonest presenting symptom; discharging sinuses with abscess formation was found in six patients, five of whom were children. MR imaging of the sacrum revealed a hypointense marrow signal on T1-weighted images and hyperintense signal on T2-weighted images in 14 of 15 patients, the S2 vertebra being always involved. CT revealed osteolytic changes in the sacrum in all the five patients in whom CT was performed. All patients showed marked clinical improvement within 1 year of anti-tuberculous chemotherapy.Conclusion. Isolated tuberculosis of the sacrum is uncommon but should be suspected in patients presenting with chronic low backache or children with discharging sinuses/abscesses and showing sacral destruction on CT or MR imaging. MR imaging can identify cases and enables early institution of anti- tuberculous chemotherapy. (orig.)

  12. The intestinal calcistat

    2013-01-01

    Full Text Available The main physiological function of vitamin D is maintenance of calcium homeostasis by its effect on calcium absorption, and bone health in association with parathyroid gland. Vitamin D deficiency (VDD is defined as serum 25-hydroxy vitamin D (25OHD levels <20 ng/ml. Do all subjects with VDD have clinical disease according to this definition? We hypothesize that there exist an intestinal calcistat, which controls the calcium absorption independent of PTH levels. It consists of calcium sensing receptor (CaSR on intestinal brush border, which senses calcium in intestinal cells and vitamin D system in intestinal cells. CaSR dampens the generation of active vitamin D metabolite in intestinal cells and decrease active transcellular calcium transport. It also facilitates passive paracellular diffusion of calcium in intestine. This local adaptation adjusts the fractional calcium absorption according the body requirement. Failure of local adaptation due to decreased calcium intake, decreased supply of 25OHD, mutation in CaSR or vitamin D system decreases systemic calcium levels and systemic adaptations comes into the play. Systemic adaptations consist of rise in PTH and increase in active vitamin D metabolites. These adaptations lead to bone resorption and maintenance of calcium homeostasis. Not all subjects with varying levels of VDD manifest with secondary hyperparathyroidism and decreased in bone mineral density. We suggest that rise in PTH is first indicator of VDD along with decrease in BMD depending on duration of VDD. Hence, subjects with any degree of VDD with normal PTH and BMD should not be labeled as vitamin D deficient. These subjects can be called subclinical VDD, and further studies are required to assess beneficial effect of vitamin D supplementation in this subset of population.

    MiniLab tuberculosis (ML TB) assay is a new automatic diagnostic tool for diagnosis of multidrug resistance tuberculosis (MDR-TB). This study was conducted with aims to know the performance of this assay. Sputum sample from 224 TB suspects was collected from tuberculosis suspects seeking medical care at Beijing Chest hospital. The sputum samples were directly used for smear and ML TB test. The left sputum sample was used to conduct Xpert MTB/RIF, Bactec MGIT culture and drug susceptibility test (DST). All discrepancies between the results from DST, molecular and phenotypic methods were confirmed by DNA Sequencing. The sensitivity and specificity of ML TB test for detecting MTBC from TB suspects were 95.1% and 88.9%, respectively. The sensitivity for smear negative TB suspects was 64.3%. For detection of RIF resistance, the sensitivity and specificity of ML TB test were 89.2% and 95.7%, respectively. For detection of INH resistance, the sensitivity and specificity of ML TB test were 78.3% and 98.1%, respectively. ML TB test showed similar performance to Xpert MTB/RIF for detection of MTBC and RIF resistance. In addition, ML TB also had good performance for INH resistance detection. Copyright © 2017.

    Full Text Available Background and Aim: Cutaneous tuberculosis (CTB is still difficult to diagnose due to its varied clinical presentation and limitations of diagnostic methods. The aim of this study was to evaluate the results of diagnostic laboratory tests available for CTB. Materials and Methods: Twenty-six skin biopsy specimens belonging to clinically suspected cases of CTB were studied retrospectively. The specimens were divided into two portions, one part processed for histopathological evaluation and the other was used for microscopy and inoculation for the isolation of mycobacteria. Polymerase chain reaction (PCR technique was applied to 14 of 26 specimens to detect Mycobacterium tuberculosis complex (MTBC DNA. Results: Of the 26 biopsy specimens, 11 were confirmed as CTB by identification of MTBC in culture and/or histopathologic affirmation. Of these, four were lupus vulgaris, four were TB verrucosa cutis, one was scrofuloderma, one was primary inoculation TB, and one was periorifical CTB. Culture for mycobacteria was positive for five (45.45% specimens, while histopathologic affirmation was obtained in ten (90.90% specimens. Acid-fast Bacilli were not demonstrated in any of the specimens on microscopic examination. The PCR was found to be applied to six of the 11 specimens diagnosed as CTB and was positive in two specimens (33.3%, which were positive for growth in culture and histopathological correlation. Conclusion: The recovery rate of MTBC from biopsy specimens was found to be satisfactory for CTB with histopathological correlation, but the combination of culture with a rapid method, PCR, may improve the diagnostic rate.

    There is a close relationship between the human host and the intestinal microbiota, which is an assortment of microorganisms, protecting the intestine against colonization by exogenous pathogens. Moreover, the intestinal microbiota play a critical role in providing nutrition and the modulation of host immune homeostasis. Recent reports indicate that some strains of intestinal bacteria are responsible for intestinal ulceration and chronic inflammation in inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) and Crohn's disease (CD). Understanding the interaction of the intestinal microbiota with pathogens and the human host might provide new strategies treating patients with IBD. This review focuses on the important role that the intestinal microbiota plays in maintaining innate immunity in the pathogenesis and etiology of UC and discusses new antibiotic therapies targeting the intestinal microbiota.

    The world is in need of more effective approaches to controlling tuberculosis. The development of improved control strategies has been hampered by deficiencies in the tools available for detecting Mycobacterium tuberculosis and defining the dynamic consequences of the interaction of M. tuberculosis with its human host. Key needs include a highly sensitive, specific nonsputum diagnostic; biomarkers predictive of responses to therapy; correlates of risk for disease development; and host response-independent markers of M. tuberculosis infection. Tools able to sensitively detect and quantify total body M. tuberculosis burden might well be transformative across many needed use cases. Here, we review the current state of the field, paying particular attention to needed changes in experimental paradigms that would facilitate the discovery, validation, and development of such tools. © 2015 Gardiner and Karp.

    In spite of a decreasing number of new cases of silico-tuberculosis even today there still remains a serious complication of silicosis. The job of radiology is to recognise the disease, evaluate the course of the disease during therapy and classify the disease for compensation purposes. Due to the pathogenetic and pathomorphologic similarities of silicosis and tuberculosis, it is often difficult and sometimes even impossible to recognise the presence of tuberculosis in cases of silicoses or to identify and isolate the TB component in silico-tuberculosis. Careful consideration of all radiological and clinical parameters improves the accuracy of diagnosis. Since the radiographic examination provides the only method of evaluating the morphologic state of the disease, radiology will keep its central position in the diagnosis of silico-tuberculosis.

    The aim of this study was to evaluate the outcome of different techniques of palliation for patients with hilar cholangiocarcinoma. All patients treated with palliative intent between 1988 and 2004 at the Royal Infirmary of Edinburgh were reviewed. Patients were analysed on an intention to treat basis. Demographics, procedure and outcome (including re-admissions) were recorded. Two hundred and thirty-three patients underwent palliative treatment for suspected hilar cholangiocarcinoma. The diagnosis was confirmed histologically in 109 patients. The procedure related morbidity and mortality was 54/225 and 18/207 respectively. Seventy-one patients required re-admission. Twenty patients underwent surgical biliary bypass for jaundice. Those undergoing surgical palliation had a longer median (95% CI) time to re-admission (16 (0-36) vs.7 (2-12) weeks, p=0.001). Endoscopic retrograde cholangio-pancreatography (ERCP) and stenting was only successful in 28 patients and was associated with a significantly higher re-admission rate compared to patients in whom ERCP was not performed (60/179 vs. 4/27, p=0.050). The overall median (95% CI) survival was 145 (124-185) days. Current options for palliation of hilar cholangiocarcinoma provide good short term success but are all associated with significant early and late morbidity. Due to its low success and association with an increased re-admission rate, ERCP for definitive palliation should not be used in the first line staging and management of these patients.

    Full Text Available Abstract Background More than 1 million tuberculosis (TB patients are receiving the standard anti-TB treatment provided by China National Tuberculosis Prevention and Control Scheme (CNTS in China every year. Adverse reactions (ADRs induced by anti-TB drugs could both do harm to patients and lead to anti-TB treatment failure. The ADACS aimed to explore ADRs' incidences, prognoses, economical and public health impacts for TB patients and TB control, and build a DNA bank of TB patients. Methods/Design Multiple study designs were adopted. Firstly, a prospective cohort with 4488 sputum smears positive pulmonary tuberculosis patients was established. Patients were followed up for 6-9 months in 52 counties of four regions. Those suspected ADRs should be checked and confirmed by Chinese State Food and Drug Administration (SFDA. Secondly, if the suspected ADR was anti-TB drug induced liver injury (ATLI, a nested case-control study would be performed which comprised choosing a matched control and doing a plus questionnaire inquiry. Thirdly, health economical data of ADRs would be collected to analyze financial burdens brought by ADRs and cost-effectiveness of ADRs' treatments. Fourthly, a drop of intravenous blood for each patient was taken and saved in FTA card for DNA banking and genotyping. Finally, the demographic, clinical, environmental, administrative and genetic data would be merged for the comprehensive analysis. Discussion ADACS will give an overview of anti-TB drugs induced ADRs' incidences, risk factors, treatments, prognoses, and clinical, economical and public health impacts for TB patients applying CNTS regimen in China, and provide suggestions for individualized health care and TB control policy.

    The World Health Organization (WHO) has declared Tuberculosis (TB) a global emergency in 1993. Prevalence of TB and Human Immunodeficiency Virus (HIV) co-infection worldwide is 0.18% and about 8% TB cases have HIV infection. Effective chemotherapy has been available for treatment of TB for over 50 years now. In World Health Organization (WHO)-International Union Against Tuberculosis and Lung Disease (IUATLD) Working Group Global Anti-Tuberculosis Drug Resistance Surveillance (1994-1997), the incidence of MDR TB in Delhi was found to be 14%, of which primary multi-drug resistance was only 1.4%, indicating that most of MDR TB is acquired as a result of poor chemotherapy. Since TB is an infectious disease caused by Mycobacterium (M) tuberculosis the diagnosis of TB should (as far as possible) be by demonstration of M. tuberculosis on culture or acid-fast bacilli (AFB) on smear examination. The World Health Organization (WHO) has strongly recommended sputum smear examination as the preferred screening test and suggests examination of 3 deeply coughed out sputum samples - spot sample on day 1, overnight sample and a spot sample in the morning on day 2. Recently it has been shown that sputum smear positivity is greater than 90% where greater than 5 ml of sputum is used for smear diagnosis of pulmonary TB. Culture of M. tuberculosis is the gold standard for diagnosis of TB. Culture of mycobacteria is a much more sensitive test than smear examination and has been estimated to detect 10-100 viable mycobacteria per ml of sample and in case of active disease they are found to be 81% sensitive and 98.5% specific. Culture methods are also required for further drug sensitivity testing in cases of suspected drug resistant cases. Isoniazid and rifampicin resistance can be reliably measured; resistance to pyrazinamide, ethambutol, and streptomycin is more difficult due to limitations of technique. The therapeutic index for a given drug is low for certain second-line drugs such as

    To highlight the recent studies which have enhanced our appreciation of the composition of the microbiota in the human small intestine and its relevance to the health of the host. In the past number of years, the composition of the microorganisms present in our small intestines has been the subject of greater scrutiny than ever before. These investigations have been possible as a consequence of the development and utilization of new molecular tools which have revolutionized the field of microbial ecology and have focused predominantly on the small intestinal microbiota associated with pediatric celiac disease, inflammatory bowel disease, irritable bowel syndrome and pouchitis. The impact of invasive procedures, such as small bowel transplant, ileostomy and ileal pouch anal anastomosis, on the ileal microbiota has also been investigated. The ever greater appreciation of the link between the small intestinal microbiota and the health status of the host has the potential to lead to the development of new strategies to alter this microbiota in a targeted way to prevent or treat specific disorders.

    Ascaris lumbricoides is the second most common intestinal parasite world-wide and, although the infection can be asymptomatic, in some cases it can present with complications, such as acute pancreatitis. We describe the case of a 37-year-old man, with a history of travelling in Eastern countries who presented with Ascaris lumbricoides-induced acute pancreatitis mimicking a small pancreatic cancer, diagnosed during an upper EUS. The endoscopy revealeda roundworm floating in the duodenum; its endoultrasonographic appearance showed a diffuse inhomogeneous pattern, with hypoechoic echotexture, such as in acute pancreatitis. Microbiological examination of the worm revealed a 20 cm long Ascaris lumbricoides. In non endemic countries, acute pancreatitis induced by Ascaris lumbricoides is an unusual diagnosis, and should be suspected especially in patients with history of traveling in endemic areas.

    Objective was to diagnose isolated tuberculosis of sternum in patients presenting with signs and symptoms suggestive of tuberculosis. A prospective study conducted at Jawaharlal Nehru Medical College, Aligrah Muslim University, Aligarh, India from July 2000 to July 2006 of 2512 patients presenting with a suspected case of tuberculosis. Cases were confirmed using different investigations along with treatment of the patients with antitubercular treatment (ATT) with further follow up for next 2 years. Nineteen patients were suffering from isolated tuberculosis of sternum. The main presenting feature was retrosternal discomfort (100%) while 14 (73.6%) patients presented with a cold abscess of sternum. All the patients were treated successfully with 12 months of ATT and followed up for 2 years for any relapse. Although tuberculosis of sternum is rare, it should be considered as an important differential diagnosis in patients presenting with chronic lesions of the sternum, particularly in endemic/developing countries. Twelve months of treatment with ATT is optimal for achieving cure without any risk of relapse. (author)

    2013-01-01

    Background: Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis. The gold standard for the diagnosis of tuberculosis is detection of Mycobacterium tubercle bacilli. However, clinical scoring systems are most widely used for the diagnosis of TB in children. Objective: To determine the diagnostic accuracy of modified Kenneth Jones scoring criteria (MKJSC) in conformed cases of tuberculosis. Methodology: This cross-sectional comparative study was conducted in the department of Paediatrics, King Edward Medical University / Mayo Hospital, Lahore from January to June 2007. One hundred children below 15 years of age were enrolled. They were diagnosed as suspected cases of TB on the basis of fever and cough for more than 15 days. MKJSC was applied and each child was subjected to confirmatory test for TB. Results: There was an overall male preponderance of 54%. The mean age of study population was 1.8 +- 0.7 years. Out of 100 children, 66% were diagnosed as TB cases (23 with confirmatory tests and 43 with MKJSC of 5 or more). Sensitivity, specificity, positive and negative predictive value of MKJSC was 73.91%, 44.16%, 28.33%, and 85% respectively. Diagnostic accuracy of MKJSC was 51%. Conclusion: Present study does not support the hypothesis that MKJSC is a good alternative to confirmatory tests to diagnose tuberculosis in children. However, MKJSC is a simple tool, which can be applied to improve the case detection rate in the absence of sophisticated tests. (author)

    Full Text Available The main aims of this study were to study the patterns of mutations in rpoB, katG, and inhA genes in Mycobacterium tuberculosis strains isolated from patients from Nepal and to evaluate the performance of genotype MTBDRplus assay, taking conventional drug susceptibility testing as gold standard for diagnosis of MDR-TB. A total of 69 Mycobacterium tuberculosis strains isolated from 73 smear positive sputum samples from patients suspected of suffering from multidrug-resistant tuberculosis were used in our study. The drug susceptibility pattern of Mycobacterium tuberculosis isolated from these sputum specimens was determined by using genotype MTBDRplus assay taking conventional drug susceptibility testing as reference. The sensitivity and specificity of the genotype MTBDRplus assay for the detection of MDR-TB were found to be 88.7% and 100%, respectively. 88.7% of the rifampicin resistant isolates had mutations in rpoB gene. Similarly, 79.7% and 9.4% of isoniazid resistant isolates had mutations in katG and inhA genes, respectively. Genotype MTBDRplus assay was found to be very rapid and highly sensitive and specific method for diagnosis of MDR-TB and will be very helpful for early diagnosis of MDR-TB in high tuberculosis burden countries.

    The coexistance among fungal pathogens and tuberculosis pulmonary is a clinical condition that generally occurs in immunosuppressive patients, however, immunocompetent patients may have this condition less frequently. We report the case of an immunocompetent patient diagnosed with coinfection Mycobacterium tuberculosis and Candida albicans. A female patient, who is a 22-years old, with fever and a new onset of hemoptysis. Diminished vesicular breath sounds in the apical region and basal crackling rales in the left lung base were found in the physical examination. Microbiological tests include: chest radiography and CAT scan pictograms in high resolution, Ziehl-Neelsen stain, growth medium for fungus and mycobacteria through Sabouraudís agar method with D-glucose. Medical examinations showed Candida albicans fungus and Mycobacterium tuberculosis present in the patient. Patient was treated with anti-tuberculosis and anti-fungal medications, which produced good responses. Pulmonary tuberculosis and fungal co-infection are not common in immunocompetent patients. However, we can suspect that there is a presence of these diseases by detecting new onset of hemoptysis in patients.

    1. Philippines: The development, expansion and maintenance of pilot area activities: Cristina B. Giango (Technical Division, Cebu Provincial Health Office, the Philippines) In 1994, the Department of Health developed the new NTP policies based on WHO recommendations and started a pilot project in Cebu Province in collaboration with the Japan International Cooperation Agency. To test its feasibility and effectiveness, the new NTP policies were pre-tested in one city and one Rural Health Unit. The test showed a high rate of three sputum collection (90%), high positive rate (10%), and high cure rate (80%). Before the new guidelines were introduced, the new policy was briefed, a baseline survey of the facility was conducted, equipment was provided, and intensive training was given. Recording/Reporting forms and procedures were also developed to ensure accurate reporting. Supervision, an important activity to ensure effective performance, was institutionalized. Laboratory services were strengthened, and a quality-control system was introduced in 1995 to ensure the quality of the laboratory services. With the implementation of DOTS strategy, barangay health workers were trained as treatment partners. In partnership with the private sector, the TB Diagnostic Committee was organized to deliberate and assess sputum negative but X-ray positive cases. The implementation of the new NTP guidelines in Cebe Province has reached a satisfactory level, the cure rate and positive rate have increased, and laboratory services have improved. Because of its successful implementation, the new NTP guidelines are now being used nationwide. 2.

    Tuberculosis is a serious public health problem worldwide. In 2012, the World Health Organization estimated 8.6 million new cases and 1.3 million deaths due to the disease. In 2011, the incidence in Colombia was 24 cases per 100,000 inhabitants. There is little information about tuberculosis in pregnant women, and congenital infection is considered a rare disease that is difficult to diagnose, leads to high mortality, and may be confused with tuberculosis acquired after birth. In addition, it has been associated with HIV infection in mothers and infants. Moreover, there is increasing incidence of congenital syphilis in the world. In Colombia, the prevalence is 2.5 cases per 1,000 births and its frequency in the Instituto Materno Infantil-Hospital La Victoria is one case per 57 births. We report the case of a newborn under treatment for congenital syphilis and in whom microcalcifications were found in a transfontanelar ultrasound. This finding warned about the existence of another infectious agent. PCR was negative for cytomegalovirus, and IgM titers for toxoplasma, rubella and herpes I and II were also negative. After learning about a history of incomplete treatment for tuberculosis in the mother, we suspected the presence of an infection by the tubercle bacillus in the newborn. No acid-fast bacilli were demonstrated in three gastric juice samples. The IS6110 PCR assay was found positive in cerebrospinal fluid and urine, but not in blood. The newborn was treated with crystalline penicillin for 10 days along with isoniazid, rifampicin, pyrazinamide and streptomycin. The patient is currently under clinical monitoring.

    Full Text Available (TB and to assess the knowledge of health personnel on fundamental concepts about TB and control measures for pulmonary tuberculosis in a hospital environment. Methods: The study was conducted in a tertiary hospital in Fortaleza-CE and involved patients admitted with TB and health professionals responsible for assistance. A first phase was characterized by a retrospective study of medical records of patients admitted with suspected TB. In a second stage, a cross-sectional study with application of a structured questionnaire assessed the knowledge of health personnel on TB control measures in a hospital environment. Results: Sixty-seven patients admitted with suspected TB had their medical records assessed. Among the confirmed cases, the most frequent clinical form was pulmonary (81.3%. Out of 55 patients admitted with suspected pulmonary tuberculosis, only 29 (52.7% were admitted in a respiratory isolation bed. Twenty-six patients with suspected pulmonary tuberculosis on admission stayed a total of 148 days out of a respiratory isolation bed (average 4.1 days / patient. The knowledge of 159 health professionals about TB was assessed. Regarding the transmission of TB, 107 (67.2% were unaware of airborne transmission and 109 (68.5% ignored the clinical forms that require respiratory isolation. Conclusions: Pulmonary tuberculosis is the most frequent clinical form among inpatients in a tertiary hospital in Fortaleza- CE. Considerable fraction of health personnel doesn’t know key concepts related to tuberculosis and essential for the proper and safe care.

  14. Suspected lamotrigine-induced toxic epidermal necrolysis.

    Chaffin, J J; Davis, S M

    1997-06-01

    To describe a patient who developed toxic epidermal necrolysis (TEN) possibly secondary to lamotrigine use. A 74-year-old white man with a history of probable complex partial seizures was admitted to the neurology service for a prolonged postictal state. His antiepileptic regimen was changed while he was in the hospital to include lamotrigine. After 19 days of hospitalization and 14 days of lamotrigine therapy, the patient became febrile. The next day he developed a rash which progressed within 4 days to TEN, diagnosed by skin biopsy. All suspected drugs were discontinued, including lamotrigine. The patient was treated with hydrotherapy in the burn unit. His symptoms improved and he was discharged from the hospital 26 days after the rash developed. During lamotrigine's premarketing clinical trials, the manufacturer reported several cases of Stevens-Johnson syndrome and TEN. There are several published case reports of lamotrigine-induced severe skin reactions. All of these reports included patients being treated with both valproic acid and lamotrigine. Our patient was exposed to phenytoin, carbamazepine, clindamycin, and lamotrigine, but not valproic acid. The patient reported prior use of phenytoin with no skin rash. Carbamazepine was the antiepileptic drug the patient was maintained on prior to his hospital admission, and the symptoms of TEN resolved while he was still receiving carbamazepine. The patient received only two doses of clindamycin, which makes this agent an unlikely cause of TEN. Because of the temporal relationship of the onset of the patient's rash and several drugs that are known to cause severe rashes, it is not certain which drug was the definite culprit. However, based on the evidence from the literature, lamotrigine appears to be the causative agent.

    To evaluate the utility of targeted exome sequencing for the molecular diagnosis of mitochondrial disorders, which exhibit marked phenotypic and genetic heterogeneity. We considered a diverse set of 102 patients with suspected mitochondrial disorders based on clinical, biochemical, and/or molecular findings, and whose disease ranged from mild to severe, with varying age at onset. We sequenced the mitochondrial genome (mtDNA) and the exons of 1,598 nuclear-encoded genes implicated in mitochondrial biology, mitochondrial disease, or monogenic disorders with phenotypic overlap. We prioritized variants likely to underlie disease and established molecular diagnoses in accordance with current clinical genetic guidelines. Targeted exome sequencing yielded molecular diagnoses in established disease loci in 22% of cases, including 17 of 18 (94%) with prior molecular diagnoses and 5 of 84 (6%) without. The 5 new diagnoses implicated 2 genes associated with canonical mitochondrial disorders (NDUFV1, POLG2), and 3 genes known to underlie other neurologic disorders (DPYD, KARS, WFS1), underscoring the phenotypic and biochemical overlap with other inborn errors. We prioritized variants in an additional 26 patients, including recessive, X-linked, and mtDNA variants that were enriched 2-fold over background and await further support of pathogenicity. In one case, we modeled patient mutations in yeast to provide evidence that recessive mutations in ATP5A1 can underlie combined respiratory chain deficiency. The results demonstrate that targeted exome sequencing is an effective alternative to the sequential testing of mtDNA and individual nuclear genes as part of the investigation of mitochondrial disease. Our study underscores the ongoing challenge of variant interpretation in the clinical setting.

    2015-01-01

    To describe the effects of suspected synthetic cannabinoid (SC) toxicosis and the response to intravenous lipid emulsion (ILE) therapy in a dog. A 2-year-8-month-old male Boxer dog was evaluated at an emergency hospital for progressive ataxia and inappropriate mentation. The initial physical examination identified marked hypothermia (32.7°C [90.9°F]), intermittent sinus bradycardia (60/min), stuporous mentation with intermittent aggression, and severe ataxia. Neurologic status deteriorated to comatose mentation within 2 hours of presentation. The initial diagnostic evaluation (eg, CBC, serum biochemistry profile, venous blood gas, and electrolyte determination) revealed a respiratory acidosis and thrombocytopenia. The owner reported that the dog was exposed to an SC containing Damiana leaf, Marshmallow leaf, and Athaea leaves. Initial treatment included IV fluids and supplemental oxygen. Mechanical ventilation was provided due to hypoventilation and periods of apnea. Intravenous lipid emulsion therapy was administered as a bolus (1.5 mL/kg) and continued as a continuous rate infusion (0.5 mL/kg/h) for a total of 6 hours. The dog became rousable and was weaned from mechanical ventilation approximately 15 hours following presentation. The dog was eating and walking with no ataxia, had a normal mentation at approximately 33 hours following presentation, and was discharged home at that time. Communication with the owners 5 days following discharge revealed that the dog was apparently normal. Based on this case and other reports in the literature regarding human exposures, SC ingestion may result in more severe clinical signs than marijuana ingestion in dogs. Significant clinical intervention may be necessary. Intravenous lipid emulsion treatment may be beneficial due to the lipophilicity of SC. © Veterinary Emergency and Critical Care Society 2015.

  17. Tuberculosis diagnostic methods in buffaloes

    2015-07-01

    Full Text Available The low productivity of buffalo herds and condemnation of carcasses in slaughterhouses due to tuberculosis lesions have resulted in increasing economic losses because these animals cannot be treated and must be destroyed by sanitary slaughter. Tuberculosis is a widely distributed zoonosis that affects the beef supply chain of the Brazilian agribusiness economically and socially. Like cattle, buffaloes are sensitive to Mycobacterium bovis, which is the main causative agent of zoonotic tuberculosis. Tuberculosis in buffaloes has been reported in several countries, including Brazil. In order to control and eradicate this disease among cattle and buffaloes in Brazil, the Ministry of Agriculture, Livestock, and Supply created the National Program for the Control and Eradication of Brucellosis and Tuberculosis with the main objective of finding a significant number of disease-free herds throughout the national territory using reliable methods. This review summarizes the main data on the history of occurrence of M. bovis in Brazilian herds and the diagnostic methods for the disease in buffaloes. Little information is available on buffalo tuberculosis. Due to the increasing population of buffaloes and their economic importance, more studies investigating the occurrence and identification of tuberculosis in this species are clearly needed.

    Because small, pliable paediatric airways are easily compressed by enlarged lymph nodes, detection of radiographic airway compression might be an objective criterion for diagnosing pulmonary tuberculosis. To investigate the frequency and inter-observer agreement of airway compression on chest radiographs in children with pulmonary tuberculosis compared to those with a different lower respiratory tract infection. Chest radiographs of children with suspected pulmonary tuberculosis were read by two readers according to a standardised format and a third reader when there was disagreement. Radiographs of children with proven pulmonary tuberculosis were compared to those with a different lower respiratory tract infection. We evaluated frequency and location of radiographic airway compression. Findings were correlated with human immunodeficiency virus (HIV) status and age. We assessed inter-observer agreement using kappa statistics. We reviewed radiographs of 505 children (median age 25.9 months, interquartile range [IQR] 14.3-62.2). Radiographic airway compression occurred in 54/188 (28.7%) children with proven pulmonary tuberculosis and in 24/317 (7.6%) children with other types of lower respiratory tract infection (odds ratio [OR] 4.9; 95% confidence interval [CI] 2.9-8.3). A higher frequency of radiographic airway compression occurred in infants (22/101, or 21.8%) compared to older children (56/404, or 13.9%; OR 1.7; 95% CI 1.0-3.0). We found no association between airway compression and HIV infection. Inter-observer agreement ranged from none to fair (kappa of 0.0-0.4). There is a strong association between airway compression on chest radiographs and confirmed pulmonary tuberculosis. However this finding's clinical use as an objective criterion for diagnosis of pulmonary tuberculosis in children is limited by poor inter-observer agreement. (orig.)

    Full Text Available Background: Tuberculosis is one of the deadly communicable diseases which claim the lives of millions in the world. Early case detection and prompt treatment cures the patients, breaks the transmission and improves the control program. Objective: The aim of this study was to investigate the factors affecting tuberculosis case detection in Kersa District, south west Ethiopia. Method: Facility based cross sectional study design was employed in four directly observed treatment short course service providing public health centers. Three hundred eighty four patient folders were reviewed. In-depth interviews was conducted with 18 health care workers including heads of health centers, tuberculosis focal persons, clinicians, laboratory technicians, tuberculosis program coordinator and head of health office. Result: Significant number, 135(35.2% of tuberculosis suspects were not requested for microscopic examination of sputum smear, the laboratory results 21(8.4% of requested patients were not recorded in both patient folders and laboratory registers. Only 10 (4.4% of those examined and recorded were smearing positive. Participants described that the shortage and irregular supply of acid fast bacilli reagents and consumable, inadequate infrastructures, frequent electricity interruption, shortage of trained care providers, negligence of care providers, weakness of laboratory quality assurance system and poor health information use culture were major factors for low case identification. Conclusion: The resource shortage, electricity interruption, low commitment of care providers, weak quality assurance practice and poor health information use culture were major factors for low tuberculosis case identification and should be considered.

Radiographic airway compression occurred in 54/188 (28.7%) children with proven pulmonary tuberculosis and in 24/317 (7.6%) children with other types of lower respiratory tract infection (odds ratio [OR] 4.9; 95% confidence interval [CI] 2.9-8.3). A higher frequency of radiographic airway compression occurred in infants (22/101, or 21.8%) compared to older children (56/404, or 13.9%; OR 1.7; 95% CI 1.0-3.0). We found no association between airway compression and HIV infection. Inter-observer agreement ranged from none to fair (kappa of 0.0-0.4). There is a strong association between airway compression on chest radiographs and confirmed pulmonary tuberculosis. However this finding's clinical use as an objective criterion for diagnosis of pulmonary tuberculosis in children is limited by poor inter-observer agreement. (orig.)

    Because small, pliable paediatric airways are easily compressed by enlarged lymph nodes, detection of radiographic airway compression might be an objective criterion for diagnosing pulmonary tuberculosis. To investigate the frequency and inter-observer agreement of airway compression on chest radiographs in children with pulmonary tuberculosis compared to those with a different lower respiratory tract infection. Chest radiographs of children with suspected pulmonary tuberculosis were read by two readers according to a standardised format and a third reader when there was disagreement. Radiographs of children with proven pulmonary tuberculosis were compared to those with a different lower respiratory tract infection. We evaluated frequency and location of radiographic airway compression. Findings were correlated with human immunodeficiency virus (HIV) status and age. We assessed inter-observer agreement using kappa statistics. We reviewed radiographs of 505 children (median age 25.9 months, interquartile range [IQR] 14.3-62.2).

    Septic peritonitis occurs relatively commonly in dogs. Secondary septic peritonitis is usually associated with perforation of intestines or infected viscera, such as the uterus in pyometra cases. The aim of this study was to evaluate the bacterial flora in the ovarian bursae of intact bitches as a potential source of contamination. One hundred forty dogs, clinically suspected of pyometra, were prospectively enrolled. The control group consisted of 26 dogs that underwent elective ovariohysterectomies and 18 dogs with mammary gland tumors that were neutered at the time of mastectomy. Bacteriology samples were taken aseptically at the time of surgery from the bursae and the uterus in all dogs. Twenty-two dogs that were clinically suspected of pyometra had sterile uterine content ("mucometra" cases); the remaining 118 had positive uterine cultures ("pyometra" cases) and septic peritoneal fluid was present in 10% of these cases. Of the 118 pyometra cases, 9 had unilateral and 15 had bilateral bacterial colonization of their ovarian bursae. However, the bacteria from the ovarian bursa were similar to those recovered from the uterine pus in only half of the cases. Furthermore, positive bursae were also seen in one mucometra dog (unilateral) and in four control dogs (two unilateral and two bilateral). The data illustrate that the canine ovarian bursa can harbor bacteria. The biological importance of these isolations remains unclear. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available The morbidity and mortality due to tuberculosis (TB is high worldwide, and the burden of disease among women is significant, especially in developing countries. Mycobacterium tuberculosis bacilli reach the genital tract primarily by haematogenous spread and dissemination from foci outside the genitalia with lungs as the common primary focus. Genital TB in females is a chronic disease with low-grade symptoms. The fallopian tubes are affected in almost all cases of genital TB, and along with endometrial involvement, it causes infertility in patients. Many women present with atypical symptoms which mimic other gynaecological conditions. A combination of investigations is needed to establish the diagnosis of female genital TB (FGTB. Multidrug anti-TB treatment is the mainstay of management and surgery may be required in advanced cases. Conception rates are low among infertile women with genital TB even after multidrug therapy for TB, and the risk of complications such as ectopic pregnancy and miscarriage is high. More research is needed on the changing trends in the prevalence and on the appropriate methods for diagnosis of FGTB.

    Full Text Available Tuberculosis (TB is a major public health concern worldwide: despite a regular, although slow, decline in incidence over the last decade, as many as 8.6 million new cases and 1.3 million deaths were estimated to have occurred in 2012. TB is by all means a poverty-related disease, mainly affecting the most vulnerable populations in the poorest countries. The presence of multidrug-resistant strains of M. tuberculosis in most countries, with some where prevalence is high, is among the major challenges for TB control, which may hinder recent achievements especially in some settings. Early TB case detection especially in resource-constrained settings and in marginalized groups remains a challenge, and about 3 million people are estimated to remain undiagnosed or not notified and untreated. The World Health Organization (WHO has recently launched the new global TB strategy for the “post-2015 era” aimed at “ending the global TB epidemic” by 2035, based on the three pillars that emphasize patient-centred TB care and prevention, bold policies and supportive systems, and intensified research and innovation. This paper aims to provide an overview of the global TB epidemiology as well as of the main challenges that must be faced to eliminate the disease as a public health problem everywhere.

  8. Simultaneous immunization against tuberculosis.

    Full Text Available BCG, the only licensed vaccine against tuberculosis, provides some protection against disseminated disease in infants but has little effect on prevention of adult pulmonary disease. Newer parenteral immunization prime boost regimes may provide improved protection in experimental animal models but are unproven in man so that there remains a need for new and improved immunization strategies.Mice were immunized parenterally, intranasally or simultaneously by both routes with BCG or recombinant mycobacterial antigens plus appropriate adjuvants. They were challenged with Mycobacterium tuberculosis (Mtb and the kinetics of Mtb growth in the lungs measured. We show that simultaneous immunization (SIM of mice by the intranasal and parenteral routes is highly effective in increasing protection over parenteral BCG administration alone. Intranasal immunization induces local pulmonary immunity capable of inhibiting the growth of Mtb in the early phase (the first week of infection, while parenteral immunization has a later effect on Mtb growth. Importantly, these two effects are additive and do not depend on priming and boosting the immune response. The best SIM regimes reduce lung Mtb load by up to 2 logs more than BCG given by either route alone.These data establish SIM as a novel and highly effective immunization strategy for Mtb that could be carried out at a single clinic visit. The efficacy of SIM does not depend on priming and boosting an immune response, but SIM is complementary to prime boost strategies and might be combined with them.

    Full Text Available A 68 years old male farmer referred with cough, expectorating sputum, intermittant fever, night sweats, fatigue and anorexia persisting for two weeks. There was a history of 80 packs each year of smoking and he was still an active smoker. Pneumonectomy was performed because of pulmonary epidermoid cancer and he received chemotherapy. He was diagnosed lung tuberculosis and using anti-tuberculous treatment for 4 months. He had a weight loss of 8 kg in last month. His body tempereature was 38.5 °C. Heart rate was 100/min. ESR was 51mm/h and CRP was 5.6 mg/ dL. There was no proliferation in blood and sputum cultures. Three sputum specimens were examined and AFB wasn’t detected. Fibronodular infiltration was seen in right lower zone of chest X-ray. In thorax CT, fibronodular densities were seen in lower lobe anterior and posterior segments. Brucella melitensis was isolated in blood culture. Second bronchoscopy was performed with suspect of brucellosis pneumonia. Brucella tube agglutination test was positive at titer 1/320 in the bronchial lavage fluid and 1/640 in concurrent serum sample. In cases with chronic cough or pneumonia which is irresponsive to nonspecific antibiotherapy, respiratory brucellosis must be rememberred in endemic areas.

    Full Text Available Nine cases of tuberculosis (TB were diagnosed among 800 uremic patients, followed-up during 11 years, a prevalence of 1125%, 2.5 times higher than that in the general population. Six patients (66.7% had lymph node involvement (4 cervical and 2 mediastinal. Three patients (33.3% had pulmonary involvement (2 pleuro-pulmonary and 1 bilateral apical pulmonary. Eight patients were undergoing dialysis and 1 was pre-dialytic. The duration of dialysis ranged from 1 to 60 months. Three patients had previously received immunosuppressive drugs for unsuccessful renal transplantation. Daily fever was present in all but one patient; he was asymptomatic and TB was suspected after routine chest radiography. Biopsy was the diagnostic procedure in 7 patients (77.8%, four by direct cervical lymph node biopsy, 2 by mediastinal, performed by mediastinoscopy and 1 by pleural biopsy. In 2 other patients TB was confirmed by the presence of tubercle bacilli; in sputum (1 patient and in a bronchial flushing specimen (the other patient. Triple therapy was used in all patients (isoniazid and ethambutol in all, plus rifampicin in 8 and streptomycin in 1. One patient had jaundice and another had optical neuritis. Five patients were cured. The other four died during treatment of causes unrelated to TB or its treatment.

    Full Text Available Introduction: Gastrointestinal tuberculosis often involves the ileocecal region. Duodenal and gastric tuberculosis found in only 1% of patients suffering from pulmonary tuberculosis with associated HIV infection in non-endemic areas. Duodenal obstruction due to tuberculosis is very rare and needs high index of suspicions for diagnosis. Mostly this entity is suspected on intraoperative findings. In this manuscript we emphasized on ways and means for establishing histopathological diagnosis before starting anti-tubercular treatment in such cases. Method and Material: All patients of suspected gastroduodenal tuberculosis presented with feature of gastric-outlet obstruction managed during Jan 2009 to June 2011 were included in the study. After proper evaluation (routine hematological and biochemical examination, microbiological examination, serological and endoscopic evaluation exploratory laparotomy was done and if there is no mesenteric lymphadenopathy or it is not safe to take biopsy form the diseased duodenum, multiple FNAC were taken from the diseased portion for histopathological and microbiological diagnosis. Result: A total of five patients were treated during this period. The most common presentation was vomiting followed by failure to thrive and weight loss; two patients had abdominal pain. Biopsy of mesenteric lymph node was possible in two cases. FNAC from diseases portion was taken in all cases. FNAC showed granulomas in four cases. Cases where even FNAC finding was non-conclusive on HPE/Microbiology was not subjected to antitubercular drug. Conclusion: Multiple intra-operative FNAC may be taken from the diseased portion of the duodenum to establish the histopathological diagnosis if diagnosis is not established by any other mean.

    The past few years have witnessed a considerable shift in the clinical status of intestinal transplantation. A great deal of experience has been gained at the most active centers, and results comparable with those reported at a similar stage in the development of other solid-organ graft programs are now being achieved by these highly proficient transplant teams. Rejection and its inevitable associate, sepsis, remain ubiquitous, and new immunosuppressant regimes are urgently needed; some may already be on the near horizon. The recent success of isolated intestinal grafts, together with the mortality and morbidity attendant upon the development of advanced liver disease related to total parenteral nutrition, has prompted the bold proposal that patients at risk for this complication should be identified and should receive isolated small bowel grafts before the onset of end-stage hepatic failure. The very fact that such a suggestion has begun to emerge reflects real progress in this challenging field.

    Introduction. The burden of tuberculosis is high in eastern Malaysia, and rates of Mycobacterium tuberculosis drug resistance are poorly defined. Our objectives were to determine M. tuberculosis susceptibility and document management after receipt of susceptibility results. Methods. Prospective study of adult outpatients with smear-positive pulmonary tuberculosis (PTB) in Sabah, Malaysia. Additionally, hospital clinicians accessed the reference laboratory for clinical purposes during the study. Results. 176 outpatients were enrolled; 173 provided sputum samples. Mycobacterial culture yielded M. tuberculosis in 159 (91.9%) and nontuberculous Mycobacterium (NTM) in three (1.7%). Among outpatients there were no instances of multidrug resistant M. tuberculosis (MDR-TB). Seven people (4.5%) had isoniazid resistance (INH-R); all were switched to an appropriate second-line regimen for varying durations (4.5-9 months). Median delay to commencement of the second-line regimen was 13 weeks. Among 15 inpatients with suspected TB, 2 had multidrug resistant TB (one extensively drug resistant), 2 had INH-R, and 4 had NTM. Conclusions. Current community rates of MDR-TB in Sabah are low. However, INH-resistance poses challenges, and NTM is an important differential diagnosis in this setting, where smear microscopy is the usual diagnostic modality. To address INH-R management issues in our setting, we propose an algorithm for the treatment of isoniazid-resistant PTB.

    Background Multiple studies of tuberculosis treatment have indicated that patients with diabetes mellitus may experience poor outcomes. We performed a systematic review and meta-analysis to quantitatively summarize evidence for the impact of diabetes on tuberculosis outcomes. Methods We searched PubMed, EMBASE and the World Health Organization Regional Indexes from 1 January 1980 to 31 December 2010 and references of relevant articles for reports of observational studies that included people with diabetes treated for tuberculosis. We reviewed the full text of 742 papers and included 33 studies of which 9 reported culture conversion at two to three months, 12 reported the combined outcome of failure and death, 23 reported death, 4 reported death adjusted for age and other potential confounding factors, 5 reported relapse, and 4 reported drug resistant recurrent tuberculosis. Results Diabetes is associated with an increased risk of failure and death during tuberculosis treatment. Patients with diabetes have a risk ratio (RR) for the combined outcome of failure and death of 1.69 (95% CI, 1.36 to 2.12). The RR of death during tuberculosis treatment among the 23 unadjusted studies is 1.89 (95% CI, 1.52 to 2.36), and this increased to an effect estimate of 4.95 (95% CI, 2.69 to 9.10) among the 4 studies that adjusted for age and other potential confounding factors. Diabetes is also associated with an increased risk of relapse (RR, 3.89; 95% CI, 2.43 to 6.23). We did not find evidence for an increased risk of tuberculosis recurrence with drug resistant strains among people with diabetes. The studies assessing sputum culture conversion after two to three months of tuberculosis therapy were heterogeneous with relative risks that ranged from 0.79 to 3.25. Conclusions Diabetes increases the risk of failure and death combined, death, and relapse among patients with tuberculosis. This study highlights a need for increased attention to treatment of tuberculosis in people with

    Our research group previously isolated and identified a strain of pathogenic Escherichia coli from clinical samples called E. coli O124 K72. The present study was aimed at determining the potential effects of E. coli O124 K72 on intestinal barrier functions and structural proteins integrity in guinea pig. Guinea pigs were grouped into three groups; control (CG); E. coli O124 K72 (E. coli); and probiotics Lactobacillus rhamnosus (LGG). Initially, we create intestinal dysbiosis by giving all animals Levofloxacin for 10days, but the control group (CG) received the same volume of saline. Then, the animals received either E. coli O124 K72 (E. coli) or Lactobacillus rhamnosus (LGG) according to their assigned group. E. coli O124 K72 treatment significantly affected colon morphology and distorted intestinal barrier function by up-regulating Claudin2 and down-regulating Occludin. In addition, E. coli upregulated the mRNA expression of MUC1, MUC2, MUC13 and MUC15. Furthermore, suspected tumor was found in the E. coli treated animals. Our results suggested that E. coli O124 K72 strain has adverse effects on intestinal barrier functions and is capable of altering integrity of structural proteins in guinea pig model while at same time it may have a role in colon carcinogenesis.

  18. Prediction of Suspect Location Based on Spatiotemporal Semantics

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The prediction of suspect location enables proactive experiences for crime investigations and offers essential intelligence for crime prevention. However, existing studies have failed to capture the complex social location transition patterns of suspects and lack the capacity to address the issue of data sparsity. This paper proposes a novel location prediction model called CMoB (Crime Multi-order Bayes model based on the spatiotemporal semantics to enhance the prediction performance. In particular, the model groups suspects with similar spatiotemporal semantics as one target suspect. Then, their mobility data are applied to estimate Markov transition probabilities of unobserved locations based on a KDE (kernel density estimating smoothing method. Finally, by integrating the total transition probabilities, which are derived from the multi-order property of the Markov transition matrix, into a Bayesian-based formula, it is able to realize multi-step location prediction for the individual suspect. Experiments with the mobility dataset covering 210 suspects and their 18,754 location records from January to June 2012 in Wuhan City show that the proposed CMoB model significantly outperforms state-of-the-art algorithms for suspect location prediction in the context of data sparsity.

  19. Chronic intestinal ischaemia: measurement of the total splanchnic blood flow.

    2013-04-01

    A redundant collateral network between the intestinal arteries is present at all times. In case of ischaemia in the gastrointestinal tract, the collateral blood supply can develop further, thus accommodating the demand for oxygen even in the presence of significant stenosis or occlusion of the intestinal arteries without clinical symptoms of intestinal ischaemia. Symptoms of ischemia develop when the genuine and collateral blood supply no longer can accommodate the need for oxygen. Atherosclerosis is the most common cause of obliteration in the intestinal arteries. In chronic intestinal ischaemia (CII), the fasting splanchnic blood flow (SBF) is sufficient, but the postprandial increase in SBF is inadequate and abdominal pain will therefore develop in relation to food intake causing the patient to eat smaller meals at larger intervals with a resulting weight loss. Traditionally, the CII-diagnosis has exclusively been based upon morphology (angiography) of the intestinal arteries; however, substantial discrepancies between CII-symptoms and the presence of atherosclerosis/stenosis in the intestinal arteries have been described repeatedly in the literature impeding the diagnosis of CII. This PhD thesis explores a method to determine the total SBF and its potential use as a diagnostic tool in patients suspected to suffer from CII. The SBF can be measured using a continuous infusion of a tracer and catheterisation of a hepatic vein and an artery. By measuring the SBF before and after a standard meal it is possible to assess the ability or inability to enhance the SBF and thereby diagnosing CII. In Study I, measurement of SBF was tested against angiography in a group of patients suspected to suffer from CII due to pain and weight loss. A very good agreement between the postprandial increase in SBF and angiography was found. The method was validated against a well-established method independent of the hepatic extraction of tracer using pAH in a porcine model (study II

    To evaluate the radiologic findings of breast tuberculosis. The authors evaluated the radiologic findings of five cases of surgically confirmed tuberculosis of the breast. Patients were examined with mammography (n=5), ultrasonography (n=3), and MRI (n=2). All patients were female. Four patients had unilateral lesion and the remaining one patient had bilateral breast tuberculosis. Mammographic findings were mainly radiopaque mass density without secondary signs. Two patients showed secondary signs such as skin thickening, parenchymal distortion, and nipple retraction. Ultrasonographic findings were variable but helpful in differentiating benign from malignant breast lesion, MRI findings were more helpful in differentiating abscess from malignant lesions. Radiologic findings were useful to diagnose tuberculosis of the breast, but fine needle aspiration biopsy and culture were needed for suspicious radiologic findings
