    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 Infection by Mycobacterium bovis is not infrequently identified in Mexico. Its relation to nonpasteurized milk products ingestion is well recognized with primary infection usually in the intestinal tract. The term “abdominal tuberculosis” includes peritoneal as well as primary and secondary intestinal tuberculosis. The clinical differentiation of these conditions is difficult. In this work, we reviewed the clinical and pathological features of 24 cases of children dying with tuberculosis in whom autopsy revealed abdominal disease in a referral hospital in Mexico City. We identified 8 cases of primary intestinal tuberculosis, with documentation of M. bovis in 6 of them, and 9 cases of secondary intestinal tuberculosis (primary pulmonary disease, all negative to M. bovis. Seven patients had peritoneal tuberculosis without intestinal lesions and with active pulmonary disease in 4 of them, and of the remaining three, two had mesenteric lymph node involvement suggesting healed intestinal disease. In this approach to abdominal tuberculosis, postmortem analysis was able to differentiate primary from secondary intestinal tuberculosis and to define the nature of peritoneal involvement. This discrimination gives rise to different diagnostic approaches and epidemiological and preventive actions, particularly in countries where tuberculosis is endemic and infection by M. bovis continues to be identified.

    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)

    A patient with a fulminant amebic colitis coexisting with intestinal tuberculosis had a sudden onset of crampy abdominal pain, mucoid diarrhea, anorexia, fever and vomiting with signs of positive peritoneal irritation. Fulminant amebic colitis occurring together with intestinal tuberculosis is an uncommon event and may present an interesting patho-etiological relationship. The diagnosis was proven by histopathologic examination of resected specimen. Subtotal colectomy including segmental resection of ileum, about 80 cm in length, followed by exteriorization of both ends, was performed in an emergency basis. Despite all measures, the patient died on the sixth postoperative day. The exact relationship of fulminant amebic colitis and intestinal tuberculosis is speculative but the possibility of a cause and effect relationship exists. Fulminant amebic colitis may readily be confused with other types of inflammatory bowel disease, such as idiopathic ulcerative colitis, Crohn's disease, perforated diverticulitis and appendicitis with perforation. This report draws attention to the resurgence of tuberculosis and amebiasis in Korea, and the need for the high degree of caution required to detect it. PMID:11194200

    Objectives: To study the outcome of intestinal tuberculosis presenting as acute abdomen. Study design: Descriptive Study. Place and Duration: Bolan Medical Complex Hospital (BMC) Quetta and Combined Military Hospital (CMH) Quetta from Nov 2003 to Nov 2005 from Bolan Medical Complex and from Nov 2005 to Nov 2006 in CMH Quetta. Material and Method: Thirty seven patients of acute abdomen presenting with intestinal obstruction were admitted; 28 from emergency department and 9 from out patient department. Twenty seven patients were from BMC and 10 from CMH Quetta. Patients were diagnosed as having abdominal tuberculosis on the basis of operative findings and histopathological reports. Results: Out of 37 patients presenting with acute abdomen due to intestinal obstruction, 54% were male and 46% were female with M: F ratio of 1: 1.2. Age of the patient ranged from 20 to 50 years, with maximum frequency between 30 to 40 years. Abdominal pain was the commonest presenting feature in all patients followed by constipation in 81.1% patients. Peritonism was seen in 27% patients. Different operative procedures performed were adhesionolysis 65.8%, segmental resection 7.9%, right hemicolectomy 10.5%, stricturoplasty 7.9% and ileostomy 1.3%. Mesenteric lymph node biopsy 40.8%. Conclusion: Intestinal tuberculosis is still a very important surgical problem in our country presenting as acute abdomen. A suspicion must always be kept during laparotomy and adequate tissue histopathology should supplement the diagnosis. (author)

    Early and accurate diagnosis of pulmonary tuberculosis (TB) is critical for successful TB control. To assist in the diagnosis of smear-negative pulmonary TB, the World Health Organisation (WHO) recommends the use of a diagnostic algorithm. Our study evaluated the implementation of the national tuberculosis programme's diagnostic algorithm in routine health care settings in Jogjakarta, Indonesia. The diagnostic algorithm is based on the WHO TB diagnostic algorithm, which had already been implemented in the health facilities. We prospectively documented the diagnostic work-up of all new tuberculosis suspects until a diagnosis was reached. We used clinical audit forms to record each step chronologically. Data on the patient's gender, age, symptoms, examinations (types, dates, and results), and final diagnosis were collected. Information was recorded for 754 TB suspects; 43.5% of whom were lost during the diagnostic work-up in health centres, 0% in lung clinics. Among the TB suspects who completed diagnostic work-ups, 51.1% and 100.0% were diagnosed without following the national TB diagnostic algorithm in health centres and lung clinics, respectively. However, the work-up in the health centres and lung clinics generally conformed to international standards for tuberculosis care (ISTC). Diagnostic delays were significantly longer in health centres compared to lung clinics. The high rate of patients lost in health centres needs to be addressed through the implementation of TB suspect tracing and better programme supervision. The national TB algorithm needs to be revised and differentiated according to the level of care.

    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.

    Introduction: Diagnostic laparoscopy allows the visual examination and documentation of intra-abdominal organs in order to detect any pathology. It is an important tool for final minimally invasive exploration of patients with abdominal tuberculosis, the diagnosis of which remains uncertain despite employing the requisite laboratory and non-invasive imaging investigations. Objective: To determine the frequency of peritoneal tuberculosis using diagnostic laparoscopy in clinically suspected cases of peritoneal tuberculosis. Study Design: Cross sectional survey. Setting: The study was conducted in all the four Surgical Wards on surgical floor of Mayo Hospital Lahore. Duration of Study with Dates: Six months (1st July 2009 to 31st December 2009). Material and Methods: 35 Patients aged between 13-60 years with clinical suspicion of peritoneal tuberculosis were selected. The patients underwent the procedure accordingly. Per operative diagnosis of peritoneal tuberculosis made on the basis of presence of any or all of the operative (laparoscopic) findings such as multiple peritoneal adhesions, fibrous bands, whitish peritoneal tubercles, omental thickening and ascites. Diagnosis was confirmed with histopathology of peritoneal tissue biopsy. Also the biochemical analysis and culture sensitivity of ascetic fluid was routinely performed if any ascites is present. Results: Out of 35 patients, 40% were males and 60% females with mean age of 24.91+-6.69 years. The Laparoscopic findings of peritoneal tuberculosis were whitish peritoneal tubercles (57.2%) peritoneal adhesions (28.6%), ascites (17.2%), omental thickening (14.3%), fibrous bands (11.4%) and swollen edematous appendix (5.7%). Eighty percent were labeled with diagnosis of peritoneal tuberculosis on basis of diagnostic laparoscopy. These patients were confirmed to have peritoneal tuberculosis on histopathology of tissue biopsy. Conclusion: Diagnostic laparoscopy is useful in patients with suspected peritoneal

    Helminths affect the outcome of tuberculosis by shifting cell mediated immune response to humoral and by total suppression of the host immune system. On the reverse, Mycobacterium infection favors immune escape of helminths. Therefore assessing helminth co-infection rate and predisposing factors in tuberculosis patients is mandatory to set strategies for better case management. Facility based cross-sectional study was conducted in Arba Minch to assess the prevalence and associated factors of intestinal helminths among pulmonary tuberculosis patients from January to August, 2016. A structured questionnaire was used to capture data about socio-demographic characteristics, clinical history and possible risk factors for intestinal helminth infections. Height and weight were measured to calculate body-mass index. Appropriate amount of stool was collected and processed by direct saline and formol-ether concentration techniques following standard protocols. All the data were analyzed using SPSS version 20.0. A total of 213 (57.3% male and 42.7% female) pulmonary tuberculosis patients were participated in the study. The overall co-infection rate of intestinal parasites was 26.3%. The infection rate of intestinal helminths account 24.4% and that of intestinal protozoa was 6.1%. Ascaris lumbricoides accounted the highest frequency of 11.3%. Living in rural residence (AOR = 3.175, 95% CI: 1.102-9.153, p = 0.032), Eating vegetables/ fruits without washing or peeling off (AOR = 2.208, 95% CI: 1.030-4.733, p = 0.042) and having body-mass index intestinal helminth infection. The infection rate by intestinal helminths was 24.4%. Ascaris lumbricoides was the most prevalent helminth. Residence, habit of washing vegetables/fruits before use and body-mass index were associated factors with intestinal helminthiasis. Therefore health care providers should screen and treat TB patients for intestinal helminthiasis in order to ensure good prognosis.

    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)

Cross-sectional study using indicators derived from the International Standards of Tuberculosis Care (ISTC) to compare the quality of TB evaluation services provided to men and women. Of 161 230 patient visits between January 2009 and December 2010, 112 329 (69.7%) were women. We considered 3308 (2.1%) patients with cough ≥2 weeks as TB suspects, of whom 1871 (56.6%) were women. Female TB suspects were less likely to be referred for sputum smear examination (45.9% vs. 61.6%, P ISTC (33.0% vs. 45.6%, P ISTC-recommended care (RR 0.79, 95%CI 0.72-0.86, P < 0.001). Strategies to ensure that women receive appropriate TB evaluation could provide a valuable opportunity for increasing case detection while also promoting equitable and universal access to care.

    Primary intestinal lymphangiectasia (Waldmann's disease) is an exudative enteropathy characterized by lymph leakage into the small bowel lumen leading to hypoalbuminemia, hypogammaglobulinemia and lymphopenia (particularly T-cell). The diagnosis is based on viewing the duodenal lymphangiectasia. A 20 years old female patient, treated for a primary intestinal lymphangiectasia, has consulted for anasarca. Etiological work-up reveals pleural and pericardial tuberculosis. The clinical aggravation of an enteropathy, particularly in adulthood, requires a search for a secondary etiology. Tuberculosis should be sought systematically.

    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

    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.

    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 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.

    Full Text Available Abstract Background In Ethiopia where there is no strong surveillance system and state of the art diagnostic facilities are limited, the real burden of tuberculosis (TB is not well known. We conducted a community based survey to estimate the prevalence of pulmonary TB and spoligotype pattern of the Mycobacterium tuberculosis isolates in Southwest Ethiopia. Methods A total of 30040 adults in 10882 households were screened for pulmonary TB in Gilgel Gibe field research centre in Southwest Ethiopia. A total of 482 TB suspects were identified and smear microscopy and culture was done for 428 TB suspects. Counseling and testing for HIV/AIDS was done for all TB suspects. Spoligotyping was done to characterize the Mycobacterium tuberculosis isolates. Results Majority of the TB suspects were females (60.7% and non-literates (83.6%. Using smear microscopy, a total of 5 new and 4 old cases of pulmonary TB cases were identified making the prevalence of TB 30 per 100,000. However, using the culture method, we identified 17 new cases with a prevalence of 76.1 per 100,000. There were 4.3 undiagnosed pulmonary TB cases for every TB case who was diagnosed through the passive case detection mechanism in the health facility. Eleven isolates (64.7% belonged to the six previously known spoligotypes: T, Haarlem and Central-Asian (CAS. Six new spoligotype patterns of Mycobacterium tuberculosis, not present in the international database (SpolDB4 were identified. None of the rural residents was HIV infected and only 5 (5.5% of the urban TB suspects were positive for HIV. Conclusion The prevalence of TB in the rural community of Southwest Ethiopia is low. There are large numbers of undiagnosed TB cases in the community. However, the number of sputum smear-positive cases was very low and therefore the risk of transmitting the infection to others may be limited. Active case finding through health extension workers in the community can improve the low case detection rate

    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.

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

    Multidrug drug-resistant tuberculosis (MDR-TB) is a major health problem and seriously threatens TB control and prevention efforts globally. Ethiopia is among the 30th highest TB burden countries for MDR-TB with 14% prevalence among previously treated cases. The focus of this study was on determining drug resistance patterns of Mycobacterium tuberculosis among MDR-TB suspected cases and associated risk factors. A cross-sectional study was conducted in Addis Ababa from June 2015 to December 2016. Sputum samples and socio-demographic data were collected from 358 MDR-TB suspected cases. Samples were analyzed using Ziehl-Neelsen technique, GeneXpert MTB/RIF assay, and culture using Lowenstein-Jensen and Mycobacterial growth indicator tube. Data were analyzed using SPSS version 23. A total of 226 the study participants were culture positive for Mycobacterium tuberculosis, among them, 133 (58.8%) participants were males. Moreover, 162 (71.7%) had been previously treated for tuberculosis, while 128 (56.6%) were TB/HIV co-infected. A majority [122 (54%)] of the isolates were resistant to any first-line anti-TB drugs. Among the resistant isolates, 110 (48.7%) were determined to be resistant to isoniazid, 94 (41.6%) to streptomycin, 89 (39.4%) to rifampicin, 72 (31.9%) to ethambutol, and 70 (30.9%) to pyrazinamide. The prevalence of MDR-TB was 89 (39.4%), of which 52/89 (58.4%) isolates were resistance to all five first-line drugs. Risk factors such as TB/HIV co-infection (AOR = 5.59, p = 0.00), cigarette smoking (AOR = 3.52, p = 0.045), alcohol drinking (AOR = 5.14, p = 0.001) hospital admission (AOR = 3.49, p = 0.005) and visiting (AOR = 3.34, p = 0.044) were significantly associated with MDR-TB. The prevalence of MDR-TB in the study population was of a significantly high level among previously treated patients and age group of 25-34. TB/HIV coinfection, smoking of cigarette, alcohol drinking, hospital admission and health facility visiting were identified as risk factors

  16. 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.

    Bovine tuberculosis (BTB) is a zoonotic disease caused by Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex (MTC). The quick and specific detection of this species is of extreme importance, since BTB may cause economic impacts, in addition to presenting imminent risks to human health. In the present study a nested real-time PCR test (nested q-PCR) was used in post-mortem evaluations to assess cattle carcasses with BTB-suspected lesions. A total of 41,193 cattle slaughtered in slaughterhouses located in the state of Mato Grosso, were examined. Of the examined animals, 198 (0.48%) showed BTB-suspected lesions. M. bovis was isolated in 1.5% (3/198) of the samples. Multiplex-PCR detected MTC in 7% (14/198) of the samples. The nested q-PCR test detected MTC in 28% (56/198) of the BTB-suspected lesions, demonstrating higher efficiency when compared to the multiplex-PCR and conventional microbiology. Nested q-PCR can therefore be used as a complementary test in the national program for control and eradication of bovine tuberculosis. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

    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.

    2004-01-01

    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)

    The aim of our study is to evaluate if in children with highly positive serology and HLA-DQ2/DQ8 (triple test, TT) and only extra-intestinal symptoms, it is possible to omit performing an intestinal biopsy for celiac disease (CD) diagnosis, as suggested by the new European Society for Pediatric Gastroenterology, Hepatology and Nutrition ESPGHAN guidelines. In this retrospective study a total of 105 patients, suspected of having CD because of extra-intestinal symptoms and showing serum tissue transglutaminase antibody (anti-tTG) and anti-endomysial antibody (EMA) measurements and HLA genotyping, were considered for the final analysis (33 boys and 72 girls; age range 1.5-17.6 years). Histological findings confirmed diagnosis of CD in 97 (92.4%) patients. Forty-one patients (39%) showed anti-tTG >10 times normal values, positive EMA and positive HLA-DQ2/DQ8 (positive TT). All of them had a diagnosis of CD, therefore there were no false positive cases. Sixty-four patients were negative for the TT. In eight cases, CD was ruled out and these were considered true negative cases. In the remaining 56 negative TT patients, intestinal biopsy confirmed CD diagnosis and they were considered false negatives. Based on these results, specificity for the TT was 100% and sensitivity was 42.3%. On the basis of the present study, diagnosis of CD can be reliably performed without a duodenal biopsy in children with only extra-intestinal symptoms.

    Objective: To study the imaging findings of disseminated pulmonary tuberculosis in patients with acquired immunodeficiency syndrome (AIDS). Methods: X-ray and multi-slice CT (MSCT) data from 33 AIDS patients with disseminated pulmonary tuberculosis confirmed by clinical manifestations and laboratory tests were analyzed retrospectively. Results: Thirty patients underwent initial chest radiography examination, 29 patients showed abnormal appearances, including bilateral disseminations in 21 patients and unilateral multiple disseminations in 8 patients. All patients underwent MSCT examination, 26 patients showed bilateral disseminations and 7 patients showed unilateral multiple disseminations. The abnormal pulmonary appearances included nodule (n = 25), miliary nodule (n = 22), air-space consolidation (n = 22), cavity (n = 11), fibrosis (n = 7), ground-glass opacity (n = 7), pneumatocele (n = 4), calcification (n = 2). There were 20 patients with more than 3 abnormal appearances and 13 patients with one or two abnormal appearances. The extra-pulmonary tuberculosis included pleural effusion (n = 33), lymphadenopathy (n = 30), intestinal tuberculosis (n = 3), splenic tuberculosis (n = 1) and cerebral tuberculosis (n = 1). Conclusion: Disseminated pulmonary tuberculosis should be highly suspected in AIDS patients with diffused nodules, miliary nodules, air-space consolidations or multiple cavities, accompanied with pleural effusion and lymphadenopathy.

    Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90%) perforations are solitary. Herein, we describe a case of a 25-year-old male who presented with generalized peritonitis requiring an emergency exploratory laparotomy, which revealed pan-enteric perforation characterized by multiple perforations of the small bowel extending 10–15 cm from the DJ flexure up to the terminal ileum. The perforations were primarily closed, while 6–8 cm of the diseased terminal ileum was resected and the two ends were brought out as double-barreled ostomy. To the best of our knowledge, such an extensive tuberculous perforation of the small bowel has not been previously reported in the literature before. PMID:26798540

    Full Text Available Abstract Background Intestinal malrotation is an incomplete rotation of the intestine. Failure to rotate leads to abnormalities in intestinal positioning and attachment that leave obstructing bands across the duodenum and a narrow pedicle for the midgut loop, thus making it susceptible to volvulus. One of the important differential diagnoses for malrotation is an allergy to cow’s milk. Several studies have described infants with surgical gastrointestinal diseases and cow’s milk allergy. However, to our knowledge, no study has reported infants with intestinal malrotation who have been symptomatic before surgery was performed and have been examined by allergen-specific lymphocyte stimulation test and food challenge tests with long-term follow-up. Case presentation The patient was a Japanese male born at 39 weeks of gestation. He was breast-fed and received commercial cow’s milk supplementation starting the day of birth and was admitted to our hospital at 6 days of age due to bilious vomiting. Plain abdominal radiography showed a paucity of gas in the distal bowel. Because we demonstrated malpositioning of the intestine by barium enema, we repositioned the bowel in a normal position by laparotomy. The patient was re-started on only breast milk 2 days post surgery because we suspected the presence of a cow’s milk allergy, and the results of an allergen-specific lymphocyte stimulation test showed a marked increase in lymphocyte response to kappa-casein. At 5 months of age, the patient was subjected to a cow’s milk challenge test. After the patient began feeding on cow’s milk, he had no symptoms and his laboratory investigations showed no abnormality. In addition, because the patient showed good weight gain and no symptoms with increased cow’s milk intake after discharge, we concluded that the present case was not the result of a cow’s milk allergy. At 1 year, the patient showed favorable growth and development, and serum allergy

    The contrast between the low proportion of tuberculosis (TB) suspects referred from private practitioners in Bali province and the high volume of TB suspects seeking care at private practices suggests problems with TB suspect referral from private practitioners to the public health sector. We aimed to identify key factors associated with the referral of TB suspects by private practitioners. We conducted a case-control study conducted in Bali province, Indonesia. The cases were private practitioners who had referred at least one TB suspect to a community health centre between 1 January 2007 and the start of data collection, while the controls were private practitioners who had not referred a single TB suspect in the same time. The following factors were independently associated with referral of TB suspects by private practitioners: having received information about the directly observed treatment short-course (DOTS) strategy (OR 2.0; 95% CI 1.1-3.8), ever having been visited by a district TB program officer (OR 2.1; 95% CI 1.0-4.5), availability of TB suspect referral forms in the practice (OR 2.8; 95% CI 1.5-5.2), and less than 5 km distance between the private practice and the laboratory for smear examination (OR 2.2; 95% CI 1.2-4.0). Education and exposure of private practitioners to the TB program improves referral of TB suspects from private practitioners to the national TB program. We recommend that the TB program provides all private practitioners with information about the DOTS strategy and TB suspect referral forms, and organizes regular visits to private practitioners.

    Full Text Available Although generally rising in incidence, intestinal tuberculosis is still rare in western countries and due to unspecific manifestations mainly as ulcerations on endoscopy, diagnosis of intestinal tuberculosis is challenging. Within this report, we describe a case of severe intestinal tuberculosis radiologically and endoscopically masquerading as colorectal cancer with peritoneal carcinomatosis. Our case exemplifies that intestinal tuberculosis needs to be considered as a differential diagnosis in patients at risk and that undelayed and sensitive diagnosis of intestinal tuberculosis is of central importance for avoiding unfavorable disease outcome.

    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

    Full Text Available Abstract Background Lower respiratory tract infection in children is increasingly thought to be polymicrobial in origin. Children with symptoms suggestive of pulmonary tuberculosis (PTB may have tuberculosis, other respiratory tract infections or co-infection with Mycobacterium tuberculosis and other pathogens. We aimed to identify the presence of potential respiratory pathogens in nasopharyngeal (NP samples from children with suspected PTB. Method NP samples collected from consecutive children presenting with suspected PTB at Red Cross Children’s Hospital (Cape Town, South Africa were tested by multiplex real-time RT-PCR. Mycobacterial liquid culture and Xpert MTB/RIF was performed on 2 induced sputa obtained from each participant. Children were categorised as definite-TB (culture or qPCR [Xpert MTB/RIF] confirmed, unlikely-TB (improvement of symptoms without TB treatment on follow-up and unconfirmed-TB (all other children. Results Amongst 214 children with a median age of 36 months (interquartile range, [IQR] 19–66 months, 34 (16 % had definite-TB, 86 (40 % had unconfirmed-TB and 94 (44 % were classified as unlikely-TB. Moraxella catarrhalis (64 %, Streptococcus pneumoniae (42 %, Haemophilus influenzae spp (29 % and Staphylococcus aureus (22 % were the most common bacteria detected in NP samples. Other bacteria detected included Mycoplasma pneumoniae (9 %, Bordetella pertussis (7 % and Chlamydophila pneumoniae (4 %. The most common viruses detected included metapneumovirus (19 %, rhinovirus (15 %, influenza virus C (9 %, adenovirus (7 %, cytomegalovirus (7 % and coronavirus O43 (5.6 %. Both bacteria and viruses were detected in 73, 55 and 56 % of the definite, unconfirmed and unlikely-TB groups, respectively. There were no significant differences in the distribution of respiratory microbes between children with and without TB.

    Objective: To analyse histomorphological and immunohistochemical analysis of small intestinal biopsies in adults suspected of celiac disease. Study Design: Descriptive study. Place and Duration of Study: Department of Histopathology, Army Medical College, Rawalpindi, from November 2014 to December 2015. Methodology: Fifty cases of small intestinal mucosal biopsies (duodenal and jejunal) were analysed in adult patients aged above 14 years suspected of celiac disease. Their histomorphological data was recorded using Modified Marsh Criteria. Type of intraepithelial lymphocytes was assessed using immunohistochemistry. Intraepithelial lymphocytes were counted both by H and E stain and immunostain CD3 and CD20. Results: Thirty-four percent patients were aged between 21 - 30 years and 22% patients aged between 41 - 50 years. There were 84% (n=42) males. Thirteen (26%) cases showed focal villous atrophy, 32 (64%) cases showed partial villous atrophy and 5 (10%) cases showed complete villous atrophy. Anti-tissue transglutaminase antibody was positive in 21 (42%) cases. CD3 immunomarker was positive for intraepithelial lymphocytes in all 50 cases while CD20 immunomarker showed focal positivity in areas with lymphoid follicle formation. The count of intraepithelial lymphocytes was found to be almost equal (with a difference of 3 - 4 lymphocytes) on both H and E stain and immunostain CD3 and CD20. Conclusion: Males aged 21 - 30 years were the most commonly affected group. The most frequent change in histology was partial villous atrophy along with lymphocytic enteritis. All the intraepithelial lymphocytes were present in crescendo-pattern of distribution. (author)

  12. Intestinal permeability and malabsorption of rifampin and isoniazid in active pulmonary tuberculosis

    Directory of Open Access Journals (Sweden)

    Valéria G. F. Pinheiro

    Full Text Available Low antimycobacterial drug concentrations have been observed in tuberculosis (TB patients under treatment. The lactulose/mannitol urinary excretion test (L/M, normally used to measure intestinal permeability, may be useful to assess drug absorption. The objective of this research was to study intestinal absorptive function and bioavailability of rifampin and isoniazid in TB patients. A cross sectional study was done with 41 patients and 28 healthy controls, using the L/M test. The bioavailabilities of rifampin (R and isoniazid (H were evaluated in 18 patients receiving full doses. Urinary excretion of mannitol and lactulose, measured by HPLC, was significantly lower in TB patients. The serum concentrations of the drugs were below the expected range for R (8-24 mcg/mL or H (3-6 mcg/mL in 16/18 patients. Analyzing the drugs individually, 12/18 patients had low serum concentrations of R, 13/18 for H and 8/18 for both drugs. We suggest that there is a decrease in the functional absorptive area of the intestine in TB patients, which would explain the reduced serum concentrations of antituberculosis drugs. There is a need for new approaches to improve drug bioavailability in TB patients.

  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.

    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.

    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.

    To present our experience with abdominal tuberculosis in children and adolescents treated in our hospital from 2003 - 2014. It is a retrospective study. We have collected clinical records of inpatients overweight or obese and only 23.33% suffered of malnutrition. TB contact was present in 10 (33.33%). Positive tuberculin skin tests were seen in 10%. Extra-abdominal tuberculosis was found in 22 patients (63.32%). 12 cases had coexisting pulmonary tuberculosis and 4 cases had pleural effusion. 12 patients (40%) had tuberculous peritonitis; 12 patients (40%) had intestinal tuberculosis and peritoneal tuberculosis and 4 patients (13.33%) had intestinal tuberculosis. Bacteriological confirmation of tuberculosis was achieved in 10 cases (33.33%). Antituberculous therapy for 6 months was effective in 29 cases. One patient died who multifocal tuberculosis with HIV had associated. Abdominal tuberculosis is seen in 4.37% of children affected with tuberculosis, of which over 63% will have extra abdominal manifestations. Abdominal tuberculosis should be considered in patients with abdominal pain, fever, weight loss and abnormal chest radiography. Imaging can be useful for early diagnosis of abdominal tuberculosis.

    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.

    Isolated hepatic tuberculosis without pulmonary or bowel involvement is a diagnostic challenge and can cause considerable morbidity. A young lady from Lahore presented with fever, pain in right hypochondria, nausea and weight loss. CT scan of abdomen showed multiple small hypodense non-enhancing lesions and a heterogeneous texture of liver. Biopsy confirmed the diagnosis of hepatic tuberculosis. It was concluded a case of isolated hepatic tuberculosis without evidence of other primary sites involvement. It is important to consider tuberculosis in the differential diagnosis when suspecting lymphoproliferative or metastatic diseases in a patient with vague symptoms and abnormal hepatic texture on CT.

    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.

    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)

    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.

    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%

    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

    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.

    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.

    The aim of the search was investigation of tuberculosis in AIDS patients. Each year 8-9 mln people fall ill of tuberculosis and one third of them die. To the infection of tuberculosis and fast development into active state are especially exposed people with AIDS. 696 people were examined on tuberculosis most of which were AIDS patients hospitalized and cured in Hospital of Infection Diseases and Prison Hospital. 159 patients were women and 537 were men. The average age was between 25 and 45 (70%). The investigated population was characterized according to age, social and living conditions, using drugs and former contact with tuberculosis. All patients suspected of tuberculosis had chest X-rayed, sputum, BAL and pleural liquor were taken to bacteriological examination when extrapulmonary tuberculosis was suspected. The material was taken adequately to the disease process: CSF, urine, lymph nodes, peritoneal fluids, blood, stool, swabs and other. Bacteriological investigations have been carried out by fast cultivating method since 1998 and rapid genetic method since 1999. Apart from modern, fast diagnostic methods, routine bacteriological procedures were applied in tuberculosis diagnosis. More than 30% of the examined population were from bad social-living conditions, 78% had risk factors, 65% were drug users. The analysis of the tuberculosis illness from 1997 to July 2001 shows growing tendency. Nowadays it is 20% cases proved by bacteriological diagnosis. The structure of falling ill with tuberculosis has changed. Considerable increase of extrapulmonary tuberculosis was observed, 20 patients died due to tuberculosis and 8 patients due to mycobacteriosis. Resistance of M.tub.complex occurred within the range of 10% cases.

    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. Conclusions : Serum ASCA is unlikely to be useful to differentiate between CD and IT in India.

    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

    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. (orig.)

    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.

    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.

    BACKGROUND: Spinal tuberculosis is a common disease in orthopedic clinical practice; however, it is seldom reported after organ transplantation. The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.

    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

  10. Should all suspected tuberculosis cases in high income countries be tested with GeneXpert?

    In countries with a low incidence of multidrug-resistant tuberculosis (MDR-TB), universal testing with GeneXpert might not be always cost-effective. This study provides hospital managers in low MDR-TB incidence countries with criteria on when decentralised universal GeneXpert testing would make sense. The alternatives taken into consideration include: universal microbiological culture and drug susceptibility testing (DST) only (comparator); as above but with concurrent centralized GeneXpert in a referral laboratory vs a decentralized GeneXpert system in every hospital to test smear-positive cases only; as above but testing all samples with GeneXpert regardless of smear status. The parameters were from the national TB statistics for England and from a systematic review. Decentralised GeneXpert to test any suspected TB case was the most cost-effective option when 6% or more TB patients belonged to the high-risk group, defined as previous TB diagnosis and or being born in countries with a high MDR-TB incidence. Hospital managers in England and other low MDR-TB incidence countries could use these findings to decide when to invest in GeneXpert or other molecular diagnostics with similar performance criteria for TB diagnostics.

    The purpose of this paper was to investigate the clinical and radiological features of pulmonary tuberculosis presenting as interstitial lung diseases (ILD). We analyzed the data of cases suspected of diffuse parenchyma lung diseases at this hospital between October 2003 and October 2007. The diagnosis of active pulmonary tuberculosis was based on epithelioid granuloma or positive acid-fast bacilli in lung biopsy and changes on serial radiographs obtained during treatment. The data of a series of 230 consecutive patients with suspected ILD were retrospectively analyzed. The diagnosis was confirmed by lung biopsy. Twelve patients were confirmed to have pulmonary tuberculosis. There were 5 males and 7 females with a mean age of 38 +/- 11 years (range, 17 - 68). The median course of disease in these patients was 3 months (range, 0.5 - 18 months). Patients with pulmonary tuberculosis presented with fever (11/12), cough (9/12), weight loss (7/12), dyspnea (7/12), lymphadenopathy (4/12), and splenohepatomegaly (2/12). On chest CT scan, ground-glass attenuation was identified in 4, bilateral patchy infiltration in 5, tree-in-bud appearance 1, and centrilobular lesions in 2 of the 12 patients. During the follow-up period (median, 9 month, range from 3 to 12 month), 11 patients improved, but 1 died of diabetic ketoacidosis. The diagnosis of pulmonary tuberculosis should be considered in suspected ILD patients presenting with fever, splenohepatomegaly and lymphadenopathy.

    In the Horn of Africa, there is a high prevalence of tuberculosis that is reported to be partly driven by multidrug-resistant (MDR) Mycobacterium tuberculosis strictu sensu strains. We conducted a prospective study to investigate M. tuberculosis complex species causing tuberculosis in Djibouti, and their in vitro susceptibility to standard anti-tuberculous antibiotics in addition to clofazimine, minocycline, chloramphenicol and sulfadiazine. Among the 118 mycobacteria isolates from 118 successive patients with suspected pulmonary tuberculosis, 111 strains of M. tuberculosis, five Mycobacterium canettii, one 'Mycobacterium simulans' and one Mycobacterium kansasii were identified. Drug-susceptibility tests performed on the first 78 isolates yielded nine MDR M. tuberculosis isolates. All isolates were fully susceptible to clofazimine, minocycline and chloramphenicol, and 75 of 78 isolates were susceptible to sulfadiazine. In the Horn of Africa, patients with confirmed pulmonary tuberculosis caused by an in vitro susceptible strain may benefit from anti-leprosy drugs, sulfamides and phenicol antibiotics.

    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.

    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 Abdominal tuberculosis (TB commonly affects the intestinal tract, lymph nodes, peritoneum, and solid organs in varying combinations. Hepatobiliary or pancreatic TB is rare and the preoperative diagnosis is difficult. Though rare, there have been a few citations of intrahepatic tuberculosis, but isolated bile duct tuberculosis is extremely rare. Here we report a case of obstructive jaundice which was initially thought to be due to lower-end cholangiocarcinoma but postoperatively it was found to be tuberculosis.

    To determine the etiological spectrum of acute intestinal obstruction in our clinical setup Military Hospital Rawalpindi. Study Design: Descriptive study. Place and Duration of Study: Surgical department of Military Hospital, Rawalpindi from Jul 2012 to Jul 2013, over a period of about 1 year. Material and Methods: A total of 120 patients with acute mechanical intestinal obstruction who underwent laparotomy were included in our study while those with non-mechanical intestinal obstruction like history of trauma and paralytic ileus were excluded from the study. All the patients were selected by non-probability purposive sampling technique. Emergency laparotomy was done and operative findings were recorded. Results: A total of 120 patients with mechanical intestinal obstruction were included in this study out of which 93 (69.17%) were female and remaining 27 (30.83%) were males. Male to female ratio was 1:2.24. Age range of patients was 22-85 years. Out of 120 patients operated for acute intestinal obstruction post-op adhesions were found in 37 (30.83%) patients followed by intestinal tuberculosis in 23 (19.17%) patients, obstructed inguinal hernias in 13 (10.83%), gut malignancies in 15 (12.5%) , Meckel's diverticulum with bands in 7 (5.83%), volvulus in 7 (5.83%), perforated appendix in 6 (5%), intussusception in 2 (1.7%), inflammatory bands in 5 (4.17%), trichobezoar and faecal impaction in 2 (1.7%) while in 3 (2.5%) patients no definite cause was found. Conclusion: Post-op adhesions are the commonest cause of mechanical intestinal obstruction in our setup followed by intestinal tuberculosis as second most common clinical pattern of presentation.

    The incidence of abdominal tuberculosis is much higher in an HIV-positive cohort. The use of laparoscopy in the diagnostic work-up of suspected abdominal tuberculosis is underutilized and its use and efficacy in the context of HIV co-infection has never been examined. A prospective clinical audit of the use of diagnostic laparoscopy was conducted in patients with clinically suspected abdominal tuberculosis but histologically or microbiologically unconfirmed tuberculosis at any site. From January 2008 to June 2010, 81 patients underwent diagnostic laparoscopy; 34 were male and 47 were female, with a mean age of 33 years, and 77 % were HIV-positive. Fifty-five patients (68 %) had positive histology or culture for tuberculosis. In 15 patients (19 %), histology revealed non-specific inflammation, no pathology was found in one patient, and no specimen was taken from one patient. Eighty percent of peritoneal deposits and 77 % of lymph nodes were positive for tuberculosis, whereas 35 % of ascitic fluid cultures were positive. In nine patients (11 %) an alternative diagnosis was found; nine patients (11 %) had conversion to laparotomy. There was no procedure-related death. Nine patients (11 %) died during the 2-month follow-up period. Diagnostic laparoscopy avoids the morbidity and mortality of laparotomy in chronically ill patients, and reduces the rate of misdiagnosis of other abdominal conditions and unnecessary long-term therapy. Diagnostic laparoscopy and tissue sampling is a viable and reliable strategy in patients with suspected abdominal tuberculosis.

    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

    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.

    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

    Full Text Available Abstract Background A mathematical model was designed to explore the impact of three strategies for better tuberculosis case finding. Strategies included: (1 reducing the number of tuberculosis patients who do not seek care; (2 reducing diagnostic delay; and (3 engaging non-DOTS providers in the referral of tuberculosis suspects to DOTS services in the Indonesian health system context. The impact of these strategies on tuberculosis mortality and treatment outcome was estimated using a mathematical model of the Indonesian health system. Methods The model consists of multiple compartments representing logical movement of a respiratory symptomatic (tuberculosis suspect through the health system, including patient- and health system delays. Main outputs of the model are tuberculosis death rate and treatment outcome (i.e. full or partial cure. We quantified the model parameters for the Jogjakarta province context, using a two round Delphi survey with five Indonesian tuberculosis experts. Results The model validation shows that four critical model outputs (average duration of symptom onset to treatment, detection rate, cure rate, and death rate were reasonably close to existing available data, erring towards more optimistic outcomes than are actually reported. The model predicted that an intervention to reduce the proportion of tuberculosis patients who never seek care would have the biggest impact on tuberculosis death prevention, while an intervention resulting in more referrals of tuberculosis suspects to DOTS facilities would yield higher cure rates. This finding is similar for situations where the alternative sector is a more important health resource, such as in most other parts of Indonesia. Conclusion We used mathematical modeling to explore the impact of Indonesian health system interventions on tuberculosis treatment outcome and deaths. Because detailed data were not available regarding the current Indonesian population, we relied on expert

    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.)

    A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis. The biopsy result was thickening of the horny layer epidermis with only a foreign body granuloma composed of inflammatory cells, and did not lead to a definitive diagnosis. Thoraca-abdominal computed tomography revealed axillary lymphadenopathy with necrosis. Suspecting tuberculosis lymphadenitis, we performed T-spot and QuantiFERONtests. The result was T-spot negative and QuantiFERONpositive, so we diagnosed the patient with penile tuberculosis, and started antituberculosis medication. In about half a year after the start of treatment the symptoms subsided, and lymphadenopathy showed reduction.

    Full Text Available In Tanzania sputum culture for tuberculosis (TB is resource intensive and available only at zonal facilities. In this study overnight pooled sputum collection technique was compared with standard spot morning collection among pulmonary TB suspects at Kibong’oto National TB Hospital in Tanzania. A spot sputum specimen performed at enrollment, an overnight pooled sputum, and single morning specimen were collected from 50 subjects and analyzed for quality, quantity, and time to detection in Bactec MGIT system. Forty-six (92% subjects’ overnight pooled specimens had a volume ≥5 mls compared to 37 (37% for the combination of spot and single morning specimens (P<0.001. Median time to detection was 96 hours (IQR 87–131 for the overnight pooled specimens compared to 110.5 hours (IQR is 137 right 137–180 for the combination of both spot and single morning specimens (P=0.001. In our setting of limited TB culture capacity, we recommend a single pooled sputum to maximize yield and speed time to diagnosis.

    In 2012 the World Health Organization reported 8.7 million new cases of Tuberculosis worldwide, causing 1.4 million deaths (1). Despite modern drug therapy, this disease continues to present in novel ways and mimic other diseases causing misdiagnosis. We report this case to educate on the reason to suspect atypical Tuberculosis presentation, even if a common disease is diagnosed, when Tuberculosis remains in the differential. We also demonstrate that with globalization and patient moving between countries, that these presentations can occur in locations, where such atypical manifestations are very uncommon. We report on a 48 year old man with one month of malaise, fever, productive cough, night sweats, chills, pleuritic chest pain, weight loss and progressive non-painful swelling on his thorax. Initial diagnoses of interstitial pneumonia and a thoracic subcutaneous abscess were made. Needle drainage was attempted, with thick purulent material returned. When the sternum was not struck with the needle, a thoracic computed tomography scan was performed. A milliary pattern was noted in the lungs, with a large abscess present anteriorly, completely obliterating the manubrium, approaching the aorta with distant lesions. Subsequent analysis showed the material to be pan-sensitive M. Tuberculosis. The issue that this case raises is that when tuberculosi is in the differential, even common diseases may in fact be atypical manifestations of tuberculosis. In addition, when a shallow surgical procedure is going to be performed on the thoracic soft tissues, particularly when tuberculosis is suspected, imaging of the thorax should be obtained.

    Tuberculosis has been declared to be a global epidemic. Despite all the effort, only less than half the annual estimated cases are reported by health authorities to the WHO. This could be due to poor reporting from the private sector. In Ethiopia, tuberculosis has also been a major public health problem. The aim of this study was to assess the role of the private health sector in tuberculosis control in Debre Markos. An institution based cross-sectional descriptive study was carried out in private health facilities. A total of 260 tuberculosis suspects attending the private clinics were interviewed. Focus group discussion, checklist, and structured questionnaire were used. Majority of the private clinics were less equipped, poorly regulated, and owned by health workers who were self-employed on a part-time basis. Provider delay of 4 and more months was significantly associated higher likelihood of turning to a private provider (OR = 2.70, 95% CI = (1.20, 6.08)). There is significant delay among tuberculosis patients. Moreover, there is poor regulation of the private health sector by public health authorities. The involvement of the private sector in tuberculosis control should be limited to identification and refer to tuberculosis cases and suspects.

    2007-05-01

    Although the prevalence of tuberculosis continues to decline in most developed countries, the risk of healthcare-associated tuberculosis, remains for patients or healthcare staff. Outbreaks of healthcare-associated tuberculosis are usually associated with delays in diagnosis and treatment, or the care of patients in sub-optimal facilities. The control and prevention of tuberculosis in hospitals is best achieved by three approaches, namely administrative (early investigation diagnosis, etc.), engineering (physical facilities e.g. ventilated isolation rooms) and personal respiratory protection (face sealing masks which are filtered). Recent guidelines on the prevention of tuberculosis in healthcare facilities from Europe and the USA have many common themes. In the UK, however, negative pressure isolation rooms are recommended only for patients with suspected multi-drug resistant TB and personal respiratory protection, i.e. filtered masks, are not considered necessary unless multi-drug resistant TB is suspected, or where aerosol-generating procedures are likely. In the US, the standard of care for patients with infectious tuberculosis is a negative pressure ventilated room and the use of personal respiratory protection for all healthcare workers entering the room of a patient with suspected or confirmed tuberculosis. The absence of clinical trials in this area precludes dogmatic recommendations. Nonetheless, observational studies and mathematical modelling suggest that all measures are required for effective prevention. Even when policies and facilities are optimal, there is a need to regularly review and audit these as sometimes compliance is less than optimal. The differences in recommendations may reflect the variations in epidemiology and the greater use of BCG vaccination in the UK compared with the United States. There is a strong argument for advising ventilated facilities and personal respiratory protection for the care of all patients with tuberculosis, as

    Full Text Available Objective/Background: The aim of this study was to analyze the detection of nontuberculous mycobacterial (NTM species derived from sputum specimens of pulmonary tuberculosis (TB suspects. Increasing prevalence and incidence of pulmonary infection by NTM species have widely been reported in several countries with geographical variation. Materials and Methods: Between January 2014 and September 2015, sputum specimens from chronic pulmonary TB suspect patients were analyzed. Laboratory examination of mycobacteria was conducted in the TB laboratory, Department of Clinical Microbiology, Dr. Soetomo Hospital, Surabaya. Detection and identification of mycobacteria were performed by the standard culture method using the BACTEC MGIT 960 system (BD and Lowenstein–Jensen medium. Identification of positive Mycobacterium tuberculosis complex (MTBC was based on positive acid-fast bacilli microscopic smear, positive niacin accumulation, and positive TB Ag MPT 64 test results (SD Bioline. If the growth of positive cultures and acid-fast bacilli microscopic smear was positive, but niacin accumulation and TB Ag MPT 64 (SD Bioline results were negative, then the isolates were categorized as NTM species. MTBC isolates were also tested for their sensitivity toward first-line anti-TB drugs, using isoniazid, rifampin, ethambutol, and streptomycin. Results: From 2440 sputum specimens of pulmonary TB suspect patients, 459 isolates (18.81% were detected as MTBC and 141 (5.78% as NTM species. Conclusion: From the analyzed sputum specimens, 18.81% were detected as MTBC and 5.78% as NTM species. Each pulmonary TB suspect patient needed clinical settings to suspect causative agents of MTBC and/or NTM species; clinicians have to understand the local epidemiological data for the evaluation of causes of lung infection to determine appropriate therapy.

    Full Text Available Aim: Abdominal tuberculosis is an uncommon form of extrapulmonary infection. In this study, we aimed to highlight the nonspecific clinical presentations and diagnostic difficulties of abdominal tuberculosis. Material and Method: Clinical features, diagnostic methods, and the therapeutic outcomes of 49 patients diagnosed as abdominal tuberculosis between 2003 and 2014 were retrospectively analyzed. Results: The patients were classified into four subgroups including peritoneal (28, nodal (14, intestinal (5, and solid organ tuberculosis (2. The most frequent symptoms were abdominal pain, abdominal distention and fatique. Ascites appeared to be the most frequent clinical finding. Ascites and enlarged abdominal lymph nodes were the most frequent findings on ultrasonography and tomography. Diagnosis of abdominal tuberculosis was mainly depended on histopathology of ascitic fluid and biopsies from peritoneum, abdominal lymph nodes or colonoscopic materials. Forty patients healed with standart 6-month therapy while extended treatment for 9-12 months was needed in 8 whom had discontinued drug therapy and had persistent symptoms and signs. One patient died within the treatment period due to disseminated infection. Discussion: The diagnosis of abdominal tuberculosis is often difficult due to diverse clinical presentations. The presence of ascites, personal/familial/contact history of tuberculosis, and coexisting active extraabdominal tuberculosis are the most significant marks in diagnosis. Diagnostic laparoscopy and tissue sampling seem to be the best diagnostic approach for abdominal tuberculosis.

    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.

    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.

    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)

    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.

    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 Purpose: Extrapulmonary tuberculosis (EPTB is emerging problem in developing and developed countries. The diagnosis of EPTB in its different clinical presentations remains a true challenge. IS6110-based polymerase chain reaction (PCR is used for rapid identification and positivity rate of the Mycobacterium tuberculosis complex in clinical isolates of different sites of EPTB. The present study was carried out to study the prevalence of M. tuberculosis complex in clinical isolates of EPTB at tertiary care centres in Lucknow. Materials and Methods: Seven hundred fifty-six specimens were collected from the suspected cases of EPTB which were processed for Mycobacteria by Ziehl Neelson (ZN staining and BACTEC culture. All the specimens were also processed for IS6110-based PCR amplification with primers targeting 123 bp fragment of insertion element IS6110 of the M. tuberculosis complex. Results: Of these 756 specimens, 71(9.3% were positive for acid fast bacilli (AFB by ZN staining, 227(30.1% were positive for mycobacteria by BACTEC culture and IS6110 PCR were positive for M. tuberculosis complex in 165 (20.7% isolates. We found a significant difference in sensitivities of different tests (P<0.05. Conclusions: This study reveals the positivity of M. tuberculosis complex in clinical isolates of EPTB case in tertiary care hospitals in Northern India. 72.7% of M. tuberculosis complex was confirmed by IS6110-PCR in culture isolates from different sites of EPTB. The high prevalence of the M. tuberculosis complex was seen in lymph node aspirate and synovial fluid. However, utility of PCR may play a potentially significant role in strengthening the diagnosis of EPTB especially targeting IS6110.

    To describe a case of tuberculosis with intestinal variant in a pregnant woman in the 17th week of pregnancy. Case report. Department of Obstetrics, Federal University of São Paulo (UNIFESP), São Paulo-SP, Brazil. Tuberculosis is a public health problem that concerns many countries in the world. It was declareda public emergency by the World Health Organization in 2005. Its presence during pregnancy brings maternal risk and fetal impairment if not treated quickly and properly. The intestinal variant is not the most common form of the disease and may be confused with inflammatory bowel diseases, especially Crohns disease. Knowledge of the specific characteristics, combined with a detailed medical history and appropriate diagnostic methods can make all the difference in gestational prognosis. We report the case of a pregnant woman who wrongly underwent treatment for inflammatory bowel disease at another service. After admission to our university hospital, fruitful diagnostic clarification was achieved and the patient was diagnosed and treated for tuberculosis. We describe the details of the investigation and, in particular, review the main characteristics in the literature for differentiating the two diseases.

    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.

    Tuberculosis (TBC) is an infectious disease with the highest mortality and morbidity by single pathogen, affecting about one third of worldwide population. Although Mantoux test is the most used, IGRA (Interferon-gamma Release Assays) tests seem to give good results for presumptive diagnosis of active or latent tuberculosis. From June 2011 to June 2012 we made about 1,000 visits for TBC prevention among the exposed to biological risks of our University. The management of suspected latent or active tuberculosis infection was carried out in collaboration with the pulmonologist, assessing the risk of contagion among exposed or affected operators. Health surveillance protocol and judgements of suitability for specific task were made not only in consideration of worker health, but also considerating the possible risk for patients, since this disease is a major problem for public health.

    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.

    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.

    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.

Of 5457 TB suspects who received PITC, 89% underwent HIV testing. Although not statistically significant, TB suspects with TB disease had an HIV prevalence of 61% compared to 63% for those without. Of the 614 suspects who declined HIV testing, 402 (65%) had TB disease. Of 2283 patients referred for cotrimoxazole prophylaxis, 1951 (86%) were enrolled, and of 1727 patients assessed for antiretroviral treatment (ART), 1618 (94%) were eligible and 1441 (83%) started treatment. PITC represents a paradigm shift and is feasible and acceptable to TB patients and TB suspects. Clear directives are nevertheless required to change practice. When offered to TB suspects, PITC identifies large numbers of persons requiring HIV care. Community sensitisation, staff training, multitasking and access to HIV care contributed to a high acceptance of HIV testing. Kenya is using this experience to inform national response and advocate wide PITC implementation in settings faced with the TB-HIV epidemic.

  6. Endocrine dysfunction among adult patients with tuberculosis: An African experience

    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.

    In a setting with a high prevalence of HIV we studied (i) the prevalence of pulmonary tuberculosis (PTB) and HIV; (ii) clinical and epidemiological characteristics of PTB; and (iii) the usefulness of standard procedures for diagnosing PTB. Of 509 consecutive outpatients evaluated on clinical suspicion of PTB in Addis Ababa, 33.0% were culture-verified as having PTB. PTB patients, non-TB patients and controls were HIV-1-positive in 57.1%, 38.5% and 8.3% of cases, respectively. Predictors for culture-verified PTB were age infection. Diagnosis of PTB based on clinical symptoms, sputum microscopy for acid-fast bacilli and chest radiography was sensitive (86.7%) but unspecific (64.1%). In HIV-positive patients both sensitivity and specificity were significantly lower (p infections are often misinterpreted as smear-negative PTB. HIV screening is therefore warranted not only in cases of verified TB but also as part of the diagnostic work-up in patients with respiratory symptoms suggestive of PTB. Also, increased awareness of, and improved diagnostic tools for, HIV-related pulmonary infections other than PTB are required, together with algorithms for patients with suspected PTB.

    Human immunodeficiency virus (HIV), tuberculosis (TB), and helminthic infections are among the commonest public health problems in the sub-Saharan African countries like Ethiopia. Multiple micronutrient deficiencies also known as the "hidden hunger" are common in people living in these countries either playing a role in their pathogenesis or as consequences. This results in a vicious cycle of multiple micronutrient deficiencies and infection/disease progression. As infection is profoundly associated with nutritional status resulting from decreased nutrient intake, decreased nutrient absorption, and nutrient losses, micronutrient deficiencies affect immune system and impact infection and diseases progression. As a result, micronutrients, immunity, and infection are interrelated. The goal of this review is therefore to provide a summary of available findings regarding the "quadruple burden trouble" of HIV, TB, intestinal parasitic infections, and multiple micronutrient deficiencies to describe immune-modulating effects related to disorders.

    1980-03-01

    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 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.

    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.

    To assess the accuracy of intestinal ultrasound for diagnosis of intestinal obstruction in dogs and cats. A prospective clinical study was performed. Inclusion criteria were dogs and cats with clinical signs suggestive of gastrointestinal obstruction. 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.

    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.

    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.

    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

    Aim: To determine the occurrence of extra-intestinal findings on magnetic resonance enterography (MRE) in a large cohort of children with known or suspected inflammatory bowel disease, characterise those findings, determine the technique and frequency of follow-up imaging, and associated costs. Materials and methods: Imaging reports from 757 MRE examinations in 671 children with known or suspected IBD from 2011 through 2012 were analysed retrospectively. Reported extra-intestinal findings were categorised by two radiologists in consensus as normal, normal variants or commonly seen findings without clinical significance, or abnormal. Prior imaging reports of the patients with abnormal findings were reviewed to identify which findings were new or substantially changed. Subsequent imaging examinations, their associated costs, and additional work-up of extra-intestinal findings were recorded in each group. Results: A total of 403 extra-intestinal findings were reported in 290 MRE (38.3%) examinations performed in 269 children (40.1%). Of these, 189 (46.9%) findings were abnormal and new or significantly changed from prior imaging, 88 (21.8%) were abnormal and stable, 50 (12.4%) were normal variants or commonly seen findings with no clinical significance, and 76 (18.9%) were normal. Abnormal findings included 34.7% associated with IBD and 65.3% considered unrelated. Follow-up imaging was performed for 69 (17.1%) mostly abnormal findings in 94 patients (8.3%). Magnetic resonance imaging (51%) and ultrasound (28%) were the most commonly utilised imaging methods. Conclusion: MRE identifies a large number of previously unknown extra-intestinal abnormalities in children with known or suspected IBD, most unrelated to IBD. Although <10% of children having MRE undergo subsequent imaging of extra-intestinal abnormalities, given the rapid uptake of MRE in the paediatric population, emphasis should be given to avoiding techniques utilising ionising radiation at follow

    Tuberculous meningitis (TBM) is closely associated with miliary tuberculosis and a pathogenetic relationship is suspected, although it has been proposed that the two processes are unrelated. To describe miliary tuberculosis of the central nervous system (CNS) on MRI in children with TBM. A retrospective descriptive study of 32 paediatric TBM patients referred for MRI. The presence of miliary nodules in the CNS was recorded. Lesions were categorized according to their distribution, enhancement pattern, size and signal characteristics. A miliary distribution of nodules was present in 88% of patients. All patients with a miliary distribution had leptomeningeal nodules and 18% of these patients had deep parenchymal nodules in addition. At least one tuberculoma with central T2 hypointensity was identified in 39% of patients. The high prevalence of miliary leptomeningeal nodules in the CNS of children with TBM is significant because it points to a pathogenetic relationship that has long been suspected on epidemiological grounds. Our findings challenge the concept that miliary tuberculosis is only an incidental finding in TBM patients and suggest that it plays an integral part in the pathogenesis. (orig.)

    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.

    Active pulmonary tuberculosis, a source of contamination, is currently undergoing a recrudescence in developed countries, particularly in clinical contexts of immuno-depression. The authors report a retrospective series of 14 cases of primary tuberculosis in a paediatric population (7 girls and 7 boys) with a mean age of 3.5 years (range: 4 months - 16 years) observed over a 3-year period. After reviewing the current radiological features of patent primary tuberculosis, the authors emphasize the contribution of chest CT scan in latent forms with a normal chest x-ray and a difficult bacteriological diagnosis. Imaging remains an essential tool in early diagnosis, therapeutic management and active surveillance of this form. The authors propose a decisional flow-chart in the case of suspected primary tuberculosis in children. (authors). 20 refs., 8 figs

    Objective: To measure the diagnostic yield of Bronchoalveolar Lavage (BAL) gene Xpert (Xpert MTB/RIF assay), to detect Mycobacterium tuberculosis (MTB) and rifampicin resistance and compare it with that of mycobacterial cultures in a suspected case of pulmonary tuberculosis. Study Design: An analytical study. Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital (FFH), Rawalpindi, from December 2012 to August 2013. Methodology: BAL specimens of 93 patients with suspected pulmonary tuberculosis with smear-negative or sputumscarce disease, who presented to the Department of Pulmonology, FFH, Rawalpindi were inducted. A smear-negative case was one in whom three consecutive early morning sputum samples did not reveal acid fast bacilli when examined by microscopy with Zeihl Nelson (ZN) stain. Patients who had sputum amount less than 1 ml were defined to have sputumscarce disease. The same was evaluated with ZN stain, gene Xpert and mycobacterial cultures. Sensitivity analysis was carried out using culture as the gold standard. Results: The frequency of positive mycobacterial cultures was 85 (91.4%). The sensitivity, specificity, positive predictive value and negative predictive values of BAL gene Xpert to detect Mycobacterium tuberculosis were 91.86%, 71.42%, 97.53% and 41.66% respectively. Xpert MTB/RIF assay had a sensitivity and specificity of 83.33% and 100% to detect rifampicin resistance. Conclusion: Bronchoalveolar lavage gene Xpert had a superior diagnostic yield in patients with either smear-negative or sputum-scarce pulmonary tuberculosis. Hence a positive Xpert MTB/RIF assay may be a useful adjunct to diagnosis and detection of MDR-TB in bronchoalveolar lavage specimens. (author)

    2016-01-01

    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.

    Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly distended bowel loops and small amount of fetal ascites.

    Full Text Available

    Background and Objectives

    Culture of M. tuberculosis is the golden standard for the diagnosis of TB which is a much more sensitive test than Smear examination. There is a strong need to use the new assays in order to speed up diagnostic methods. The aim of this research was to determine the evaluation of Microscopic Observation Drug Susceptibility culture in pulmonary tuberculosis in comparison with Ziehl-Neelsen stain and Lowenstein-Jensen culture of sputum.

     

    Methods

    The research method was a Cross-sectional (diagnostic test and the technique was observational-interview type. If the patient's history revealed clinical criteria compatible with TB and the infectious specialist’s judgment was that of "TB suspected case, the patient was considered a pulmonary TB suspect. Then, in addition to sputum Ziehl-Neelsen stain and culture for Lowenstein-Jensen, we carried out MODS culture as well.

     

    Results

    100 patients (48 male, 52 female with mean age of 52.9 ± 21.83 were evaluated. During sputum examination, 40% were Ziehl-Neelsen stain positive while 30% had positive sputum culture for Mycobacterium Tuberculosis in Lowenstein-Jensen and 47% had positive MODS culture. In comparison with sputum smear and Lowenstein-Jensen culture, MODS had a sensitivity of 82.5% and 86%, specificity of 77% and 70%, positive predictive value of 70% and 55%, negative predictive value of 86% and 92%, respectively.

     

    Conclusion

    MODS culture demonstrated faster recovery and higher negative predictive value than by Lowenstein-Jensen method; it could be a simple and rapid method in the diagnosis of pulmonary tuberculosis.

    2008-02-22

    Primary intestinal lymphangiectasia (PIL) is a rare disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. Prevalence is unknown. The main symptom is predominantly bilateral lower limb edema. Edema may be moderate to severe with anasarca and includes pleural effusion, pericarditis or chylous ascites. Fatigue, abdominal pain, weight loss, inability to gain weight, moderate diarrhea or fat-soluble vitamin deficiencies due to malabsorption may also be present. In some patients, limb lymphedema is associated with PIL and is difficult to distinguish lymphedema from edema. Exsudative enteropathy is confirmed by the elevated 24-h stool alpha1-antitrypsin clearance. Etiology remains unknown. Very rare familial cases of PIL have been reported. Diagnosis is confirmed by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of intestinal biopsy specimens. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Differential diagnosis includes constrictive pericarditis, intestinal lymphoma, Whipple's disease, Crohn's disease, intestinal tuberculosis, sarcoidosis or systemic sclerosis. Several B-cell lymphomas confined to the gastrointestinal tract (stomach, jejunum, midgut, ileum) or with extra-intestinal localizations were reported in PIL patients. A low-fat diet associated with medium-chain triglyceride supplementation is the cornerstone of PIL medical management. The absence of fat in the diet prevents chyle engorgement of the intestinal lymphatic vessels thereby preventing their rupture with its ensuing lymph loss. Medium-chain triglycerides are absorbed directly into the portal venous circulation and avoid lacteal overloading. Other inconsistently effective

Edema may be moderate to severe with anasarca and includes pleural effusion, pericarditis or chylous ascites. Fatigue, abdominal pain, weight loss, inability to gain weight, moderate diarrhea or fat-soluble vitamin deficiencies due to malabsorption may also be present. In some patients, limb lymphedema is associated with PIL and is difficult to distinguish lymphedema from edema. Exsudative enteropathy is confirmed by the elevated 24-h stool α1-antitrypsin clearance. Etiology remains unknown. Very rare familial cases of PIL have been reported. Diagnosis is confirmed by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of intestinal biopsy specimens. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Differential diagnosis includes constrictive pericarditis, intestinal lymphoma, Whipple's disease, Crohn's disease, intestinal tuberculosis, sarcoidosis or systemic sclerosis. Several B-cell lymphomas confined to the gastrointestinal tract (stomach, jejunum, midgut, ileum or with extra-intestinal localizations were reported in PIL patients. A low-fat diet associated with medium-chain triglyceride supplementation is the cornerstone of PIL medical management. The absence of fat in the diet prevents chyle engorgement of the intestinal lymphatic vessels thereby preventing their rupture with its ensuing lymph loss. Medium-chain triglycerides are absorbed directly into the portal venous circulation and avoid lacteal overloading. Other

    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.

    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.

    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.

    Full Text Available Objective: Inelaborate use of new quinolones with strong anti-tuberculosis (TB activity leads to difficulty in diagnosis and more importantly, quinolone-resistant Mycobacterium tuberculosis. We aimed to determine the frequency of quinolone use in patients who were referred to our hospital for suspected TB and to evaluate the association between quinolone use and different clinical laboratory parameters. Methods: Between November 15 and December 15, 2013, all patients who were admitted to the TB outpatient clinic with no previous diagnosis of TB were included in this study. Demographic and clinical laboratory findings and history of antibiotic use were recorded. Patients’ quinolone use were questioned by showing fluoroquinolone antibiotic boxes’ photographs available on the market. The departments of the doctors who prescribed quinolones were recorded. Results: The mean age of 179 patients included in the study was 37±16 (15–89 years. Among these, 113 patients (63.1% were male. Seventy five patients (41.9% were diagnosed as tuberculosis according to the clinical-radiological and/or bacteriological findings. Of 179 patients, 58.1% (n=104 had been prescribed antibiotics for current complaints before referral to our clinic. Sixteen patients (15% had been recommended fluoroquinolones. Fluoroquinolones were prescribed by seven internal medicine specialists, five pulmonologists, three emergency medicine specialists, and one family medicine practitioner. Among 16 fluoroquinolones prescribed, nine were moxifloxacin, four were levofloxacin, and three were gemifloxacin. Quinolone use revealed a significant inverse relationship only with the presence of hemoptysis (p=0.04. Conclusion: Besides increased educational activities regarding the rational use of antibiotics in recent years, the quinolone group of antibiotics is still prescribed for suspected TB cases. To avoid quinolone-resistant M. tuberculosis strains, further education is required.

    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)

    To determine rates of drug resistance in new cases of pulmonary tuberculosis in a region with a high burden of the disease. New case suspects were referred for drug susceptibility testing. 28.9% of new cases were resistant to at least one first line drug; 3.9% had a multidrug-resistant strain, 15.6% a monoresistant strain and 9.4% a polyresistant strain. Our rate of drug resistant tuberculosis in new cases is very high; this has important clinical implications, since even monoresistance can have a negative impact on the outcome of new cases treated empirically with a six month regimen.

    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 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.

    Ingested magnets can cause intestinal fistulas, perforation, and obstruction. There have been reports of magnet ingestion causing intestinal volvulus, but multiple magnet ingestion causing perforation and intestinal volvulus in a child is very unusual. We report the case of a 4-year-old girl, who ingested four magnets she acquired as toys, which caused intestinal volvulus and perforation as a result of pressure necrosis, several days after ingestion. At surgery we repaired two perforations, but additional bowel resection was not required. The patient was discharged on postoperative day 10. If multiple magnet ingestion is suspected in a child, the child must be monitored carefully. If there are signs of obstruction, emergency surgery is mandatory.

    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.

    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.

    Fetal intestinal volvulus is a rare but serious finding with a high risk of potential life threatening fetal complications. Delay in diagnosis or treatment can increase mortality and morbidity. We report a case of mild fetal bowel dilatation at 30 weeks of gestation and intestinal volvulus presented by the 'whirl-sign', intestinal perforation and meconium peritonitis with fetal ascites and polyhydramnios at 33 weeks of gestation. This case emphasizes the role of examination of the bowel in third trimester ultrasound and the importance of quick decision to delivery and interdisciplinary perinatal management at suspected fetal volvulus with bowel necrosis and intraabdominal bleeding.

    Fetal intestinal volvulus is a rare life-threatening condition. Late diagnosis of volvulus contributes to high rate of morbidity and mortality. It has variable degrees of presentation and survival. Intrauterine volvulus may be complicated by intestinal atresia due to ischemic necrosis. To our knowledge, there are three reported cases of term fetal demise. We report a case of fetal intestinal volvulus with perinatal survival of the largest term infant described with this complication to date. The volvulus was associated with type 3A jejunal atresia and intestinal pathology was noted on prenatal ultrasound. The infant was born via urgent cesarean delivery at 37(6/7) weeks of gestation and underwent emergent exploratory laparotomy with resection of small bowel and primary end-to-end anastomosis. Intrauterine intestinal volvulus may be suspected on prenatal ultrasound but only definitively diagnosed postnatally. Signs of fetal distress and volvulus are rarely associated with reports of survival in the term fetus. We review reported cases of prenatally suspected volvulus in infants documented to survive past the neonatal period. As fetal volvulus and most intestinal atresias/stenoses manifest during the third trimester, we recommend that the limited fetal anatomical survey during growth ultrasounds at 32 to 36 weeks routinely include an assessment of the fetal bowel.

    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

    Paragonimiasis is a neglected tropical disease caused by an infection with lung flukes that is transmitted through the consumption of undercooked crabs. The disease is often confused with tuberculosis. Paragonimiasis is thought to be endemic in south-western Côte d'Ivoire. Two cross-sectional surveys were carried out in the first half of 2009 in patients attending two tuberculosis centres of Abidjan. A third cross-sectional survey was conducted in May 2010 in children of two primary schools in Dabou, where crabs are frequently consumed. Patients with chronic cough provided three sputum samples plus one stool sample. Sputum samples were examined for tuberculosis with an auramine staining technique and for Paragonimus eggs using a concentration technique. Stool samples were subjected to the Ritchie technique. Schoolchildren provided a single stool sample, and samples were subjected to the Kato-Katz and an ether-concentration technique. A pre-tested questionnaire was administered to patients and schoolchildren to investigate food consumption habits. Additionally, between June 2009 and August 2010, shellfish were purchased from markets in Abidjan and Dabou and examined for metacercariae. No human case of paragonimiasis was diagnosed. However, trematode infections were seen in 32 of the 272 shellfish examined (11.8%). Questionnaire results revealed that crab and pig meat is well cooked before consumption. Among the 278 patients with complete data records, 62 had tuberculosis, with a higher prevalence in males than females (28.8% vs. 13.9%, χ2 = 8.79, p = 0.003). The prevalence of helminths and intestinal protozoa was 4.6% and 16.9%, respectively. In the school survey, among 166 children with complete data records, the prevalence of helminths and intestinal protozoa was 22.3% and 48.8%, respectively. Boys had significantly higher prevalences of helminths and intestinal protozoa than girls. Hookworm was the predominant helminth species and Entamoeba coli was the most

    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 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

    OBJECTIVE: To recommend guidelines for the management of tuberculosis (TB), particularly in high-risk groups including poor and homeless people, aboriginal Canadians, immigrants from countries where TB is highly prevalent and people with HIV infection. OPTIONS: Diagnosis, pharmacotherapy, vaccination and chemoprophylaxis. OUTCOMES: Prevention of infection and diagnosis and cure of TB. EVIDENCE: The evidence was gathered in late 1992 from previous guidelines, recommendations by specialist societies and new studies. VALUES: Evidence was categorized into four levels: I, randomized clinical trials of therapeutic interventions or prospective studies of diagnostic strategies; II, case-control studies; III, retrospective descriptive studies; and IV, consensus of the committee members and published statements. The Tuberculosis Committee of the Canadian Thoracic Society comprises experts in TB from across Canada. BENEFITS, HARM AND COSTS: The benefits of early diagnosis and prompt initiation of therapy are well documented. The cost effectiveness of antituberculous therapy in developing countries is well documented. In developed countries chemoprophylaxis has been shown to be cost effective, and directly observed chemotherapy has recently been hypothesized to have economic benefits. RECOMMENDATIONS: In the appropriate clinical setting, particularly when patients are known to be at high risk of TB, clinicians should consider TB, reserve body secretions for mycobacteriologic tests and conduct other investigations such as chest radiography. Furthermore, if TB is strongly suspected or confirmed by appropriate investigation the early initiation of multi-drug therapy, including at least three first-line drugs, is strongly recommended. If drug resistance is suspected a regimen of four to five drugs, including at least two drugs with which the patient has not been treated, should be started. If the strain is found to be resistant to any of the drugs in the regimen appropriate

    Objective: To compare the sensitivity of tuberculin skin test (TST) and quantiFERON-TB gold test (QFT-G) in active pulmonary tuberculosis. Study Design: Analytical study. Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital, Rawalpindi, from July 2011 to January 2012. Methodology: QuantiFERON-TB gold test (QFT-G) was evaluated and compared it with tuberculin skin test (TST) in 50 cases of active pulmonary tuberculosis, in whom tuberculous infection was suspected on clinical, radiological and microbiological grounds. Sensitivity was determined against positive growth for Mycobacterium tuberculosis. Results: Out of 50 cases, 43 were females and 7 were males. The mean age was 41.84 A+- 19.03 years. Sensitivity of QFT-G was 80% while that of TST was 28%. Conclusion: QFT-G has much higher sensitivity than TST for active pulmonary tuberculosis. It is unaffected by prior BCG administration and prior exposure to atypical mycobacteria. A positive QFT-G result can be an adjunct to diagnosis in patients having clinical and radiological data compatible with pulmonary tuberculosis. (author)

    Intraocular tuberculosis remains a diagnostic and management conundrum for both ophthalmologists and pulmonologists. We analyze the efficacy and safety of anti-tubercular therapy (ATT) in patients with intraocular tuberculosis and factors associated with favorable outcome. Twenty-eight studies are included in this review, with a total of 1,917 patients. Nonrecurrence of inflammation was observed in pooled estimate of 84% of ATT-treated patients (95% CI 79-89). There was minimal difference in the outcome between patients treated with ATT alone (85% successful outcome; 95% CI 25-100) and those with concomitant systemic corticosteroid (82%; 95% CI 73-90). The use of ATT may be of benefit to patients with suspected intraocular tuberculosis; however, this conclusion is limited by the lack of control group analysis and standardized recruitment and treatment protocols. We propose further prospective studies to better establish the efficacy of ATT and ascertain the factors associated with favorable treatment outcomes. Copyright © 2016 Elsevier Inc.

    Full Text Available Objective. To determine rates of drug resistance in new cases of pulmonary tuberculosis in a region with a high burden of the disease. Materials and methods. New case suspects were referred for drug susceptibility testing. Results. 28.9% of new cases were resistant to at least one first line drug; 3.9% had a multidrug-resistant strain, 15.6% a monoresistant strain and 9.4% a polyresistant strain. Conclusion. Our rate of drug resistant tuberculosis in new cases is very high; this has important clinical implications, since even monoresistance can have a negative impact on the outcome of new cases treated empirically with a six month regimen.

    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

    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.

    Full Text Available Genital tuberculosis is usually diagnosed in young women being assessed for infertility. After menopause it usually presents with symptoms resembling endometrial malignancy, such as postmenopausal bleeding, persistent vaginal discharge and pyometra. The diagnosis is made by detection of acid-fast bacilli on microscopy or bacteriological culture and/or presence of epithelioid granuloma on biopsy. Anti-tubercular therapy involves the use of rifampicin, isoniazid, pyrazinamide and ethambutol. Surgery is indicated if a pelvic mass and recurrence of pain or bleeding persist after 9 months of treatment. Three cases of genital tuberculosis in postmenopausal women with different clinical presentations are reported. The first woman presented with ascites and weight loss. The second had postmenopausal bleeding with a pipelle biopsy suggestive of endometrial intraepithelial neoplasia. The third presented with weight loss and a palpable abdominal mass. Pelvic malignancy was initially suspected but a diagnosis of tuberculosis was made following pre-operative endometrial biopsy, bacteriological culture and intra-operative frozen section. All three women responded to anti-tubercular therapy. Keywords: Genital tuberculosis, Postmenopausal, Endometrial intraepithelial neoplasia, Anti-tubercular therapy, Endometrial biopsy

    We report a case of a 42-year-old man with a rare disorder known as primary intestinal lymphangiectasia, which is characterized by dilated intestinal lymphatics that lead to the development of protein-losing enteropathy. The patient presented with a grand mal seizure caused by malabsorption-derived electrolytes and a protein disorder. Signs of the disease, including chronic diarrhea and peripheral edema, manifested 10 years ago, but a diagnosis was never made. The diagnosis was suspected because of the clinical manifestations, laboratory tests, imaging and endoscopic findings. Hyperemic and edematous mucosa of the small intestine corresponded to scattered white spots with dilated intestinal lymphatics and whitish villi in the histological specimen of the biopsied jejunal mucosa. Although numerous therapeutic strategies are available, only octreotide therapy proved to be an effective means of therapeutic resolution in this patient. Although the patient had a partial remission following the use of a slow release formula of octreotide, his prognosis, clinical course, and future treatment challenges are yet to be determined.

    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.

    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.

    Full Text Available Abstract Background The effects of helminth co-infection on malaria in humans remain uncertain. This study aimed to evaluate the nature of association of intestinal helminths with prevalence and clinical outcomes of Plasmodium infection. Methods A cross-sectional study involving 1,065 malaria suspected febrile patients was conducted at Dore Bafeno Health Center, Southern Ethiopia, from December 2010 to February 2011. Plasmodium and intestinal helminth infections were diagnosed using Giemsa-stained blood films and Kato-Katz technique, respectively. Haemoglobin level was determined using a haemocue machine. Results Among 1,065 malaria suspected febrile patients, 28.8% were positive for Plasmodium parasites (P. falciparum =13.0%, P. vivax =14.5%, P. falciparum and P. vivax =1.3%. Among 702 patients who provided stool samples, 53.8%, 31.6% and 19.4% were infected with intestinal helminths, Plasmodium alone and with both Plasmodium and intestinal helminths, respectively. The prevalence of infections with Ascaris lumbricoides (A. lumbricoides, Trichuris trichiura (T. trichiura, Schistosoma mansoni (S. mansoni and hookworm (9.8% were 35.9%, 15.8%, 11.7% and 9.8%, respectively.

    There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB) in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV) co-infection in a national referral hospital in Phnom Penh, Cambodia. Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB). The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (pCambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

    Technetium-99m MIBI was developed as a myocardiac perfusion imagine agent and has been used effectively in the detection and post-therapeutic evaluation of various neoplasm such as thyroid, lung, bone and breast tumors. As an infrequent findings, Tc-99m MIBI agent has shown in non-neoplastic pulmonary conditions including fibroding alveolitis, pulmonary actinomycosis, active pulmonary sarcoidosis, pulmonary interstitial fibrosis in progressive systemic sclerosis and active osteomyelitis. In a recent report conducted by Cetin Oncel, Tc-99m MIBI imaging is an effective method in the detection and follow-up of pulmonary tuberculosis. We have also experienced Tc-99m-MIBI uptake in active pulmonary tuberculosis incidentally found in a patient with suspected proliferative villonodular synovitis of the left ankle.

    Seventy one patients with active pulmonary tuberculosis who died during the past 5 years (1989 to 1993) were evaluated on their causes of death. Twenty two patients (31%) died directly of tuberculosis, and among them, 18 patients (81%) of 22 patients who died of tuberculosis) had very advanced tuberculosis. The majority of them (64%) were old age over 70 years and were bedridden due mostly to cerebrovascular injuries. The serum level of albumin was low in all 17 patients in whom it was measured. Establishment of diagnosis of tuberculosis was delayed over one month after the onset of symptoms in 59% of patients who died of severe disease. Sixty one percent (11/18) of patients died within the first month after the initiation of chemotherapy and about 90% (16/18) died within 3 months. Two patients died from massive hemoptysis and other patients died of either respiratory failure or tuberculosis meningitis. From these observations it was found that very advanced tuberculosis was the major cause of death in patients who died of tuberculosis and that the advanced disease was chiefly caused by the delay on the establishment of diagnosis, and it was most important to detect tuberculosis as early as possible, with regular check up of chest X-ray and frequent examination for AFB (acid-fast bacilli) for tuberculosis suspected patients. On the other hand, the majority of patients (49/71) died of complicating medical problem unrelated to tuberculosis. Seventeen patients died from malignancy (seven lung cancer, four lymphoma, two laryngeal cancer, etc). Ten deaths were the result of bacterial superinfection. Other patients died from respiratory failure due to COPD, arteiosclerotic heart disease, or cerebrovascular injuries, etc. Two patients of old age died of hepatic failure possibly caused by adverse reaction of TB chemotherapy. It was found that diseases unrelated to tuberculosis were the cause of death in approximately 70% of patients with active tuberculosis, and it should

    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

    In 2007 WHO issued a guideline to improve the diagnosis of smear-negative and extrapulmonary tuberculosis (EPTB) in HIV-positive patients. This guideline relies heavily on the acceptance of HIV-testing and availability of chest X-rays. Cohort study of TB suspects in four tuberculosis (TB) clinics in Phnom Penh, Cambodia. We assessed the operational performance of the guideline, the incremental yield of investigations, and the diagnostic accuracy for smear-negative tuberculosis in HIV-positive patients using culture positivity as reference standard. 1,147 (68.9%) of 1,665 TB suspects presented with unknown HIV status, 1,124 (98.0%) agreed to be tested, 79 (7.0%) were HIV-positive. Compliance with the guideline for chest X-rays and sputum culture requests was 97.1% and 98.3% respectively. Only 35 of 79 HIV-positive patients (44.3%) with a chest X-ray suggestive of TB started TB treatment within 10 days. 105 of 442 HIV-positive TB suspects started TB treatment (56.2% smear-negative pulmonary TB (PTB), 28.6% smear-positive PTB, 15.2% EPTB). The median time to TB treatment initiation was 5 days (IQR: 2-13 days), ranging from 2 days (IQR: 1-11.5 days) for EPTB, over 2.5 days (IQR: 1-4 days) for smear-positive PTB to 9 days (IQR: 3-17 days) for smear-negative PTB. Among the 34 smear-negative TB patients with a confirmed diagnosis, the incremental yield of chest X-ray, clinical suspicion or abdominal ultrasound, and culture was 41.2%, 17.6% and 41.2% respectively. The sensitivity and specificity of the algorithm to diagnose smear-negative TB in HIV-positive TB suspects was 58.8% (95%CI: 42.2%-73.6%) and 79.4% (95%CI: 74.8%-82.4%) respectively. Pending point-of-care rapid diagnostic tests for TB disease, diagnostic algorithms are needed. The diagnostic accuracy of the 2007 WHO guideline to diagnose smear-negative TB is acceptable. There is, however, reluctance to comply with the guideline in terms of immediate treatment initiation.

    Full Text Available Lin Ho Wong,1 Endean Tan2 1University College Cork, Cork, Ireland; 2Tan Tock Seng Hospital, Singapore Abstract: Oculogyric crisis (OGC, frequently caused by medications such as antiemetics, antidepressants, and anti-epileptics, is an acute dystonic reaction of the ocular muscles. It consists of wide-staring gaze (lasting variably from seconds to minutes, seizures, and a widely-opened mouth. To date, there have been no reports of anti-tuberculosis medications such as rifampicin, isoniazid, pyrazinamide or ethambutol inducing OGC. It is of utmost importance to recognize this adverse reaction, which could be incorrectly diagnosed as an anaphylactic-like reaction. In this paper, we highlight a case of a 66-year-old Indian man who presented with OGC induced by anti-tuberculosis medications which was initially suspected to be an anaphylactic reaction and was subsequently halted with the administration of diphenhydramine.

    The aim of this study was to assess the epidemiology of intestinal parasitoses during a 5-year period in patients attending a tertiary-care hospital in a non-endemic setting. In the period 2006-2010, 15,752 samples from 8,886 patients with clinically suspected parasitosis were subjected to macroscopic and microscopic examination, to parasitic antigen detection assays, and to cultures for protozoa and nematodes. Real-time PCR assays for the differentiation of Entamoeba histolytica and E. dispar and for the detection of Dientamoeba fragilis were also used.A statistical analysis evaluating the demographic data of the patients with intestinal parasitic infections was performed. Intestinal parasitic infections were diagnosed in 1,477 patients (16.6% prevalence), mainly adults and immigrants from endemic areas for faecal-oral infections; protozoa were detected in 93.4% and helminths in 6.6% of the cases, the latter especially in immigrants. Blastocystis hominis was the most common intestinal protozoan, and G. intestinalis was the most frequently detected among pathogenic protozoa, prevalent in immigrants, males, and pediatric patients. Both single (77.9%) and mixed (22.1%) parasitic infections were observed, the latter prevalent in immigrants. Despite the importance of the knowledge about the epidemiology of intestinal parasitoses in order to adopt appropriate control measures and adequate patient care all over the world, data regarding industrialized countries are rarely reported in the literature. The data presented in this study indicate that intestinal parasitic infections are frequently diagnosed in our laboratory and could make a contribution to stimulate the attention by physicians working in non-endemic areas on the importance of suspecting intestinal parasitoses.

    The effects of helminth co-infection on malaria in humans remain uncertain. This study aimed to evaluate the nature of association of intestinal helminths with prevalence and clinical outcomes of Plasmodium infection. A cross-sectional study involving 1,065 malaria suspected febrile patients was conducted at Dore Bafeno Health Center, Southern Ethiopia, from December 2010 to February 2011. Plasmodium and intestinal helminth infections were diagnosed using Giemsa-stained blood films and Kato-Katz technique, respectively. Haemoglobin level was determined using a haemocue machine. Among 1,065 malaria suspected febrile patients, 28.8% were positive for Plasmodium parasites (P. falciparum =13.0%, P. vivax =14.5%, P. falciparum and P. vivax =1.3%). Among 702 patients who provided stool samples, 53.8%, 31.6% and 19.4% were infected with intestinal helminths, Plasmodium alone and with both Plasmodium and intestinal helminths, respectively. The prevalence of infections with Ascaris lumbricoides (A. lumbricoides), Trichuris trichiura (T. trichiura), Schistosoma mansoni (S. mansoni) and hookworm (9.8%) were 35.9%, 15.8%, 11.7% and 9.8%, respectively. Out of the 222 (31.6%) Plasmodium infected cases, 9 (4.1%) had severe malaria. P. falciparum infection was more common in febrile patients infected with A. lumbricoides alone (21.3%), T. trichiura alone (23.1%) and S. mansoni alone (23.1%) compared to those without intestinal helminth infections (9.3%) (phelminths than in those who were not infected with intestinal helminths (adjusted OR=1.58, 95% CI=1.13-2.22). The chance of developing non-severe P. falciparum malaria were 2.6, 2.8 and 3.3 times higher in individuals infected with A. lumbricoides alone, T. trichiura alone and S. mansoni alone, respectively, compared to intestinal helminth-free individuals (phelminth species (phelminth infected individuals was significantly increased with the number of intestinal helminths species (p=0.027).

    Tuberculosis is a public health problem in Mexico. From 1999 to 2002, we assessed retrospectively the epidemiological, clinical, and treatment characteristics of pulmonary tuberculosis in the hospitals of the Mexican Institute of Public Health in the state of Colima (Mexico). We included 184 cases diagnosed with pulmonary tuberculosis. A database containing demographic, epidemiological, and clinical information was constructed and analyzed. We estimate a median patient delay of 83 d and a mean treatment delay of 2.3 d. Of 14 cases suspected for multiresistance and microbiologically assayed, 5 were found to carry a multi-drug-resistant strain. We also found a significant association between a short patient delay and the presence of hemoptysis (p = 0.002) or dyspnea (p<0.001). 86 patients (46.8%) were sputum smear microscopy negative at the end of treatment and 40 (21.7%) completed treatment giving an overall success rate of 68.5%, which compares unfavorably with the World Health Organization target success rate of 85%. Five (2.7%) patients failed treatment, 10 (5.4%) died, 39 (21.2%) interrupted treatment, and 4 (2.2%) transferred to another reporting unit. A 2002 strategic change in drug distribution seemed to prove successful.

    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.

    Tuberculosis remains one of the communicable diseases that cause increased morbidity and mortality worldwide. With an incidence rate of 13,04 per 100,000 population, Spain ranks third among the most affected European countries. These data show a tendency to decrease meaning that it may go unnoticed with the potential to miss the appropriate preventive measures in a suspected case. In centers where patients are treated with tuberculosis, health care worker presents risk of transmission. This risk is higher in some areas or work units. The Occupational health physicians' services, which monitorize the health of health care workers, use different strategies in order to prevent and detect tuberculosis infection. The national guidelines include the tuberculin skin test as a screening test for tuberculosis infection with mention of new diagnostic tests based on the in vitro detection of gamma interferon (IGRA) for certain cases. The purpose of this guide is to establish common criteria for IGRA tests, as a supplementary aid to the tuberculin skin test in health care workers, from the evidence available today. Recommendations for its use have been adapted to the different situations faced by the professionals involved in monitoring the health of health workers. Copyright © 2015 Elsevier España, S.L.U.

    Multidrug-resistant tuberculosis (MDR-TB) is a well-identified raising public health concern worldwide. However, the data available on MDR-TB in children and particularly in the neonate age group are limited. Congenital tuberculosis (TB) is rare, and its diagnosis is challenging because of non-specific manifestations. The choice of anti-tubercular drugs is difficult because of the lack of international consensus as a consequence of the scarcity of evidence-based data on this age group. We hereby present a case from Bhutan of a 23-day-old male neonate with congenital MDR-TB. His mother was diagnosed with disseminated TB, and treatment was commenced 11 days post-partum. Congenital transmission of TB was suspected, as direct postnatal transmission was unlikely and thorough screening of contacts for TB was negative. In this case, the mother's MDR-TB status was revealed only after her newborn's MDR-TB diagnosis.

    Full Text Available Background At present of the limitation of the current case finding strategies and the global urgency to improve tuberculosis (TB case finding, a renewed interest in active case finding (ACF has risen. World Health Organization (WHO calls for research on TB screening among low-income countries because of the limitation of the passive case finding strategies. We aimed to evaluated Active Case Finding strategy for TB among the slums population in North of Iran (Gorgan city and comprise this procedure to Passive Case Finding. Materials and Methods We conducted a house-to-house survey from April 2016 to July 2016 by trained health volunteers for TB in ten urban slums of Gorgan. Individuals with TB symptoms were identified through targeted screening using a standardized questionnaire and investigated further for TB. Descriptive analyses were performed using Stata-12. Results During study period, of 22,741 individuals screened for TB, 112 (0.49% were identified as TB suspects; 95 suspects were evaluated for TB. TB was diagnosed in four individuals, representing 4.2% of those evaluated for TB as suspected cases. The incidence rate of tuberculosis was 17.5 in 100.000 people in slums population of Gorgan. Of the four detected cases, three individuals had pulmonary TB that among them two cases had new smear-positive TB. Conclusion ACF could supplement current strategies to yield additional TB cases, lead to early diagnosis and better treatment.

    Gastric emptying time and small intestinal transit time in dogs are frequently discussed. However, it is often of interest to the radiologist to know what normal small intestinal emptying times should be. A total of 15 upper gastrointestinal studies was performed on five internal parasite-free, normal, standard Beagle dogs with three studies on each dog, 6 days apart. The ages and weights of the dogs ranged from 2–8 years and from 12.4–13.7 kg, respectively. Following 24-hour fasting, a dose of 10 ml/kg bw of 60% wt/vol barium sulfate suspension was administered through a stomach tube. Then, sequential radiographs were made at 30-minute intervals until the entire contrast medium column was in the colon and cecum. The mean, standard deviation, and range of gastric emptying time, small intestinal transit time, and small intestinal emptying time were 76 ± 16.7 (30–120), 73 ± 16.4 (30–120), and 214 ± 25.1 (180–300) minutes, respectively. This study offers the possibility that small intestinal emptying time may be used to further evaluate patients with suspected small intestinal partial obstruction, pseudo-obstruction, ischemia, or lymphangiectasia

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.)

    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 Abstract Background For a regional project in four low-incidence states, we designed a customizable tuberculosis outbreak response plan. Prior to dissemination of the plan, a tuberculosis outbreak occurred, presenting an opportunity to perform a field assessment of the plan. The purpose of the assessment was to ensure that the plan included essential elements to help public health professionals recognize and respond to outbreaks. Methods We designed a semi-structured questionnaire and interviewed all key stakeholders involved in the response. We used common themes to assess validity of and identify gaps in the plan. A subset of participants provided structured feedback on the plan. Results We interviewed 11 public health and six community stakeholders. The assessment demonstrated that (1 almost all of the main response activities were reflected in the plan; (2 the plan added value by providing a definition of a tuberculosis outbreak and guidelines for communication and evaluation. These were areas that lacked written protocols during the actual outbreak response; and (3 basic education about tuberculosis and the interpretation and use of genotyping data were important needs. Stakeholders also suggested adding to the plan questions for evaluation and a section for specific steps to take when an outbreak is suspected. Conclusion An interactive field assessment of a programmatic tool revealed the value of a systematic outbreak response plan with a standard definition of a tuberculosis outbreak, guidelines for communication and evaluation, and response steps. The assessment highlighted the importance of education and training for tuberculosis in low-incidence areas.

    In 2005, the World Health Assembly resolved that all Member States should ensure that all persons with tuberculosis (TB) "have access to the universal standard of care based on proper diagnosis, treatment and reporting consistent with the DOTS strategy..." The purpose of the International Standards for Tuberculosis Care (ISTC) is to define the widely accepted level of care of persons either suspected of, or diagnosed with, TB by all health practitioners, especially those in the private sector, who often lack guidance and systematic evaluation of outcomes provided by government programs. Since their publication in 2006 on World TB Day, the standards have been endorsed by the major international health organizations as well as many country-level professional societies. The intention is to complement local and national control polices consistent with those of the World Health Organization: they are not intended to replace local guidelines, but are written to accommodate local differences in practice. The ISTC comprise seventeen evidence-based standards on tuberculosis diagnosis and treatment, as well as the responsibility of the public health sector. These are based on the basic principles of TB care: prompt and accurate diagnosis, standardized treatment regimens of proven efficacy, appropriate treatment support and supervision, monitoring of response to treatment and the carrying out of essential public health responsibilities. The relevance of the ISTC to the Japanese context is highlighted, in terms of when persons should be suspected of TB; the appropriate diagnostic modalities, including the use of chest radiographs; the advantages of fixed dose combinations; the importance of follow-up laboratory tests to document response to treatment, the importance of recordkeeping and reporting to public health authorities, the value of HIV testing of TB patients and the use of anti-retrovirals for those dually infected; and the assessment of drug resistance and the

    The polymerase chain reaction (PCR) and its variations, such as the nested-PCR, have been described as promising techniques for rapid diagnosis of tuberculosis (TB). With the aim of evaluating the usefulness of a nested-PCR method on samples of blood and urine of patients suspected of tuberculosis we analyzed 192 clinical samples, using as a molecular target the insertion element IS6110 specific of M. tuberculosis genome. Nested-PCR method showed higher sensitivity in patients with extrapulmonary tuberculosis (47.8% and 52% in blood and urine) when compared to patients with the pulmonary form of the disease (sensitivity of 29% and 26.9% in blood and urine), regardless of the type of biological sample used. The nested-PCR is a rapid technique that, even if not showing a good sensitivity, should be considered as a helpful tool especially in the extrapulmonary cases or in cases where confirmatory diagnosis is quite difficult to be achieved by routine methods. The performance of PCR-based techniques should be considered and tested in future works on other types of biological specimens besides sputum, like blood and urine, readily obtainable in most cases. The improving of M. tuberculosis nested-PCR detection in TB affected patients will give the possibility of an earlier detection of bacilli thus interrupting the transmission chain of the disease.

    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.

    Full Text Available BACKGROUND: In 2007 WHO issued a guideline to improve the diagnosis of smear-negative and extrapulmonary tuberculosis (EPTB in HIV-positive patients. This guideline relies heavily on the acceptance of HIV-testing and availability of chest X-rays. METHODS AND FINDINGS: Cohort study of TB suspects in four tuberculosis (TB clinics in Phnom Penh, Cambodia. We assessed the operational performance of the guideline, the incremental yield of investigations, and the diagnostic accuracy for smear-negative tuberculosis in HIV-positive patients using culture positivity as reference standard. 1,147 (68.9% of 1,665 TB suspects presented with unknown HIV status, 1,124 (98.0% agreed to be tested, 79 (7.0% were HIV-positive. Compliance with the guideline for chest X-rays and sputum culture requests was 97.1% and 98.3% respectively. Only 35 of 79 HIV-positive patients (44.3% with a chest X-ray suggestive of TB started TB treatment within 10 days. 105 of 442 HIV-positive TB suspects started TB treatment (56.2% smear-negative pulmonary TB (PTB, 28.6% smear-positive PTB, 15.2% EPTB. The median time to TB treatment initiation was 5 days (IQR: 2-13 days, ranging from 2 days (IQR: 1-11.5 days for EPTB, over 2.5 days (IQR: 1-4 days for smear-positive PTB to 9 days (IQR: 3-17 days for smear-negative PTB. Among the 34 smear-negative TB patients with a confirmed diagnosis, the incremental yield of chest X-ray, clinical suspicion or abdominal ultrasound, and culture was 41.2%, 17.6% and 41.2% respectively. The sensitivity and specificity of the algorithm to diagnose smear-negative TB in HIV-positive TB suspects was 58.8% (95%CI: 42.2%-73.6% and 79.4% (95%CI: 74.8%-82.4% respectively. CONCLUSIONS: Pending point-of-care rapid diagnostic tests for TB disease, diagnostic algorithms are needed. The diagnostic accuracy of the 2007 WHO guideline to diagnose smear-negative TB is acceptable. There is, however, reluctance to comply with the guideline in terms of immediate treatment

    Majority of children with tuberculosis are treated in private sector in India with no available data on management practices. The study assessed diagnostic and treatment practices related to childhood pulmonary tuberculosis among paediatricians in Mumbai's private sector in comparison with International Standards for Tuberculosis Care (ISTC) 2009. In this cross-sectional study, 64 paediatricians from private sector filled self-administered questionnaires. Cough was reported as a symptom of childhood TB by 77.8% of respondents. 38.1% request sputum smear or culture for diagnosis and fewer (32.8%) use it for patients positive on chest radiographs and 32.8% induce sputum for those unable to produce it. Sputum negative TB suspect is always tested with X-ray or tuberculin skin test. 61.4% prescribe regimen as recommended in ISTC and all monitor progress to treatment clinically. Drug-resistance at beginning of treatment is suspected for child in contact with a drug-resistant patient (67.7%) and with prior history of antitubercular treatment (12.9%). About half of them (48%) request drug-resistance test for rifampicin in case of nonresponse after two to three months of therapy and regimen prescribed by 41.7% for multidrug-resistant TB was as per ISTC. The study highlights inappropriate diagnostic and treatment practices for managing childhood pulmonary TB among paediatricians in private sector.

    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.

    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

    Microscopy of stool samples is a labour-intensive and inaccurate technique for detection of intestinal parasites causing diarrhoea and replacement by PCR is attractive. Almost all cases of diarrhoea induced by parasites over a nine-year period in our laboratory were due to Giardia lamblia......, Cryptosporidium species, or Entamoeba histolytica detected by microscopy. We evaluated and selected in-house singleplex real-time PCR (RT-PCR) assays for these pathogens in 99 stool samples from patients suspected of having intestinal parasitosis tested by microscopy. The strategy included a genus-specific PCR...... assay for C. parvum and C. hominis, with subsequent identification by a PCR that distinguishes between the two species. G. lamblia was detected in five and C. parvum in one out of 68 microscopy-negative samples. The performance of the in-house RT-PCR assays was compared to three commercially available...

    A 23-year-old male tawny eagle (Aquila rapax) was examined because of sudden onset of lethargy, regurgitation, and hematochezia. An intestinal obstruction was suspected based on radiographic findings, and an ileo-ceco-rectal intussusception was confirmed by coelioscopy. A 14.3-cm section of intestine was resected before an intestinal anastomosis was done. Coelomic endoscopic examination confirmed a postsurgical complication of adhesions between the intestinal anastomosis and the dorsal coelomic wall, resulting in a partial luminal stricture and requiring surgical removal of the adhesions. Rectoscopy was useful in diagnosing a mild luminal stricture related to the second surgery. Complete recovery was observed 2 months after surgery. Lack of further complications in the 2 years after surgery demonstrates good tolerance of intestinal resection and anastomosis of a large segment of bowel in an eagle. This report is the first reported case of intussusception in an eagle and emphasizes the potential use of endoscopic examination in the diagnosis as well as in the management of complications.

    Inexpensive, rapid, and reliable tests for detecting the presence and drug susceptibility of Mycobacterium tuberculosis complex (MTBC) are urgently needed to control the transmission of tuberculosis. In this study, we aimed to assess the accuracy and speed of the microscopic-observation drug susceptibility (MODS) assay in the identification of MTBC and detection of multidrug resistance. Sputum samples from patients suspected to have tuberculosis were simultaneously tested with MODS and conventional culture [Löwenstein-Jensen (LJ) culture, BACTEC MGIT™ 960 (MGIT) system], and drug susceptibility testing (MGIT system) methods. A total of 331 sputum samples were analyzed. Sensitivity and specificity of MODS assay for detection of MTBC strains were 96% and 98.8%, respectively. MODS assay detected multidrug resistant MTBC isolates with 92.3% sensitivity and 96.6% specificity. Median time to culture positivity was similar for MGIT (8 days) and MODS culture (8 days), but was significantly longer with LJ culture (20 days) (p tuberculosis and detection of multidrug resistance. © 2017 APMIS.

    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.

    2016-05-01

    Full Text Available Introduction: The risk of transmission from the index case to its contacts is more in case of smear positive Pulmonary Tuberculosis cases. Any delay in diagnosis and treatment increases the risk of disease transmission to their contacts. Contact screening is important for early detection of transmission of infection. Thus, active case finding of TB is needed to identify the case yield among household contacts. This study will yield the burden of Tuberculosis among the household contact. Objective: To identify the TB suspect and estimate the prevalence of TB among household contacts. Material and Methods: A two stage cross study was done in 472 households of 157 ‘Index cases’ registered in the State Tuberculosis Unit, Puducherry. The study duration was one year and eight months. Data was entered and analyzed by using Epi_Info (Version 3.4.3 software package. Results: A total of 96 (20.3% symptomatic was found from the 472 households contacts who participated in this study. Out of 90 symptomatics, 70 (72.9% were symptomatic within two months of visit and 26 (27.1% were found to have symptoms after eight months. The overall prevalence of tuberculosis in symptomatic household contacts was 4.3% and all tuberculosis confirmed cases were found at the end of in second month only. Conclusion: Considering the prevalence tuberculosis among the symptomatic of household contact to be 4.3%, their investigation to rule out TB in earlier stages is a need. It may help prevent further spread of M. tuberculosis infection in the local community.

    Purpose: To describe CT morphology of untreated adrenal tuberculosis during the different stages of the natural history of the disease and to evaluate the diagnostic implications of CT features. Materials and methods: We retrospectively evaluated CT features in 42 patients with documented adrenal tuberculosis for the location, size, morphology, and enhancement patterns shown on CT images. The clinical duration were correlated with the CT features. Results: Of the 42 patients with untreated adrenal tuberculosis, bilaterally enlarged adrenal glands were revealed in 38 cases (91%), unilaterally enlarged in 3 cases (7%), and normal size in 1 case (2%). Of the 41 cases (98%) with enlargement, mass-like enlargement was seen in 20 cases (49%) and enlargement with preserved contours in 21 cases (51%). Peripheral rim enhancement presented in 22 cases (52%) on contrast-enhanced CT. Non-enhanced CT scan revealed calcification in 21 cases (50%). As the duration of Addison's disease increased, the presence of calcification and contour preservation increased concomitantly (p < 0.001), whereas peripheral rim enhancement and mass-like enlargement decreased concomitantly on CT images (p < 0.001). Conclusion: CT may be helpful in diagnosing adrenal tuberculosis when clinically suspected, and CT features are correlated to the clinical duration of Addison's disease

    Full Text Available On World Tuberculosis (TB Day 2006, the International Standards for Tuberculosis Care (ISTC was officially released and widely endorsed by several agencies and organizations. The ISTC release was the culmination of a year long global effort to develop and set internationally acceptable, evidence-based standards for tuberculosis care. The ISTC describes a widely endorsed level of care that all practitioners, public and private, should seek to achieve in managing individuals who have or are suspected of having, TB and is intended to facilitate the effective engagement of all healthcare providers in delivering high quality care for patients of all ages, including those with smear-positive, smear-negative and extra-pulmonary TB, TB caused by drug-resistant Mycobacterium tuberculosis and TB/HIV coinfection. In this article, we present the ISTC, with a special focus on the diagnostic standards and describe their implications and relevance for laboratory professionals in India and worldwide. Laboratory professionals play a critical role in ensuring that all the standards are actually met by providing high quality laboratory services for smear microscopy, culture and drug susceptibility testing and other services such as testing for HIV infection. In fact, if the ISTC is widely followed, it can be expected that there will be a greater need and demand for quality assured laboratory services and this will have obvious implications for all laboratories in terms of work load, requirement for resources and trained personnel and organization of quality assurance systems.

    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.

    Full Text Available ABSTRACT Objective: To determine the proportional distribution of endobronchial tuberculosis (EBTB subtypes and to evaluate the types of bronchoscopic diagnostic procedures that can prove granulomatous inflammation. Methods: This was a retrospective study of 18 HIV-negative patients with biopsy-proven EBTB treated between 2010 and 2014. Results: The most common EBTB subtypes, as classified by the bronchoscopic features, were tumorous and granular (in 22.2% for both. Sputum smear microscopy was performed in 11 patients and was positive for AFB in 4 (36.3%. Sputum culture was also performed in 11 patients and was positive for Mycobacterium tuberculosis in 10 (90.9%. Smear microscopy of BAL fluid (BALF was performed in 16 patients and was positive for AFB in 10 (62.5%. Culture of BALF was also performed in 16 patients and was positive for M. tuberculosis in 15 (93.7%. Culture of BALF was positive for M. tuberculosis in 93.7% of the 16 patients tested. Among the 18 patients with EBTB, granulomatous inflammation was proven by the following bronchoscopic diagnostic procedures: bronchial mucosal biopsy, in 8 (44.4%; bronchial brushing, in 7 (38.8%; fine-needle aspiration biopsy, in 2 (11.1%; and BAL, in 2 (11.1%. Bronchial anthracofibrosis was observed in 5 (27.7% of the 18 cases evaluated. Conclusions: In our sample of EBTB patients, the most common subtypes were the tumorous and granular subtypes. We recommend that sputum samples and BALF samples be evaluated by smear microscopy for AFB and by culture for M. tuberculosis, which could increase the rates of early diagnosis of EBTB. We also recommend that bronchial brushing be employed together with other bronchoscopic diagnostic procedures in patients suspected of having EBTB.

    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.)

    Avian tuberculosis is usually caused by the bacterium Mycobacterium avium. At least 20 different types of M. avium have been identified, only three of which are known to cause disease in birds. Other types of Mycobacterium rarely cause tuberculosis in most avian species; however, parrots, macaws, and other large perching birds are susceptible to human and bovine types of tuberculosis bacilli. Avian tuberculosis generally is transmitted by direct contact with infected birds, ingestion of contaminated feed and water, or contact with a contaminated environment. Inhalation of the bacterium can cause respiratory tract infections. Wild bird studies in the Netherlands disclosed tuberculosis-infected puncture-type injuries in birds of prey that fight at the nest site (kestrels) or on the ground (buteo-type buzzards), but tuberculosisinfected injuries were not found in accipiters (falco

    For an effective control of tuberculosis, rapid detection of multidrug resistant tuberculosis (MDR-TB) is necessary. Therefore, we developed a modified nested multiplex allele-specific polymerase chain reaction (MAS-PCR) method that enables rapid MDR-TB detection directly from sputum samples. The efficacy of this method was evaluated using 79 sputum samples collected from suspected tuberculosis patients. The performance of nested MAS-PCR method was compared with other MDR-TB detection methods like drug susceptibility testing (DST) and DNA sequencing. As rifampicin (RIF) resistance conforms to MDR-TB in greater than 90% cases, only the presence of RIF-associated mutations in rpoB gene was determined by DNA sequencing and nested MAS-PCR to detect MDR-TB. The concordance between nested MAS-PCR and DNA sequencing results was found to be 96·3%. When compared with DST, the sensitivity and specificity of nested MAS-PCR for RIF-resistance detection were determined to be 92·9 and 100% respectively. For developing- and high-TB burden countries, molecular-based tests have been recommended by the World Health Organization for rapid detection of MDR-TB. The results of this study indicate that, nested MAS-PCR assay might be a practical and relatively cost effective molecular method for rapid detection of MDR-TB from suspected sputum samples in developing countries with resource poor settings. © 2016 The Society for Applied Microbiology.

    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. PMID:25838829

    Full Text Available Whole genome sequencing (WGS can provide a comprehensive analysis of Mycobacterium tuberculosis mutations that cause resistance to anti-tuberculosis drugs. With the deployment of bench-top sequencers and rapid analytical software, WGS is poised to become a useful tool to guide treatment. However, direct sequencing from clinical specimens to provide a full drug resistance profile remains a serious challenge. This article reviews current practices for extracting M. tuberculosis DNA and possible solutions for sampling sputum. Techniques under consideration include enzymatic digestion, physical disruption, chemical degradation, detergent solubilization, solvent extraction, ligand-coated magnetic beads, silica columns, and oligonucleotide pull-down baits. Selective amplification of genomic bacterial DNA in sputum prior to WGS may provide a solution, and differential lysis to reduce the levels of contaminating human DNA is also being explored. To remove this bottleneck and accelerate access to WGS for patients with suspected drug-resistant tuberculosis, it is suggested that a coordinated and collaborative approach be taken to more rapidly optimize, compare, and validate methodologies for sequencing from patient samples.

    An emergency department encounters a variety of cases, including rare cases of the strangulation of a mesenteric lipoma by the greater omentum band. A 67-year-old Japanese man presented with nausea, vomiting, and upper abdominal pain. There were no abnormalities detected by routine blood tests other than a slight rise in his white cell count. A contrast-enhanced computed tomography scan of his abdomen revealed a dilated intestine, a small intestine volvulus, and a well-capsulated homogeneous mass. He was suspected of having a small intestine volvulus that was affected by a mesenteric lipoma; therefore, single-port laparoscopic surgery was performed. Laparoscopy revealed a small intestine volvulus secondary to the strangulation of a mesenteric lipoma. The band and tumor were removed. He had no postoperative complications and was discharged on postoperative day 6. Although this case was an emergency, it showed that single-port laparoscopic surgery can be a safe, useful, and efficacious procedure.

    Full Text Available Tuberculosis, known as the "White Plague" in the early 19th century, is the infectious disease, which is being researched today even in some of the most developed countries in the world. Epidemiological- epizootiological research points to the importance of pasteurizing milk as well as the transmission in aerosolized droplets in humans and animals. Mycobacterium tuberculosis (Mtb, M. bovis, M. africanum and M. microti are the mycobacteria that cause tuberculosis. Other mycobacteria cause diseases commonly known as mycobacteriosae. Pathogenesis of tuberculosis includes both host- related and mycobacterium-related factors (virulence. Mtb acts through the expression of various genes and their proteins that are detectable in the serums of the diseased only, proving these proteins are formed in the course of the disease. In humans, a diagnosis is established by the detection of antigens (and antibodies, and in animals, with the allergy tests. As far as the bovine tuberculosis is concerned, the combination of skin tuberculin and blood gamma interferon test is recommended. Sequential genome (Mtb analysis has given the basis for further research of the new vaccines.Key words: Tuberculosis, pathogenesis, immunity

    Malnutrition and intestinal parasites cause immunosuppression. This may cause false-negative tuberculin skin tests (TST) and failure to identify tuberculosis (TB) infection. To assess factors associated with TST positivity and anergy in disadvantaged communities in Peru. A study of 212 randomly selected adults: 102 in a rural Amazonian village and 110 shanty town residents in urban Lima. Respectively 52% and 53% of urban and rural jungle populations were TST-positive. Using simultaneous tetanus and candida skin tests, 99% had at least one positive skin test. Generalised anergy was therefore rare, despite frequent intestinal parasitic infection, including 34% helminth infection prevalence in the jungle. TST positivity was associated with age (P = 0.001), known TB contact (P = 0.02) and poor household ventilation (P = 0.007). TST positivity was not significantly associated with crowding, reported past TB, single/multiple BCG vaccination, income, intestinal parasites, dietary factors, body mass index or body fat. Individuals with lower anthropometric body protein, as measured by corrected arm muscle area, were less likely to be TST-positive (P = 0.02), implying that protein malnutrition caused tuberculin-specific anergy. These results identify the importance of household ventilation for community TB transmission and add to the evidence that protein malnutrition suppresses TB immunity, causing false-negative TST results.

    The billions of people with latent tuberculosis infection serve as the seedbeds for future cases of active tuberculosis. Virtually all episodes of tuberculosis disease are preceded by a period of asymptomatic Mycobacterium tuberculosis infection; therefore, identifying infected individuals most likely to progress to disease and treating such subclinical infections to prevent future disease provides a critical opportunity to interrupt tuberculosis transmission and reduce the global burden of tuberculosis disease. Programs focusing on single strategies rather than comprehensive programs that deliver an integrated arsenal for tuberculosis control may continue to struggle. Tuberculosis preventive therapy is a poorly utilized tool that is essential for controlling the reservoirs of disease that drive the current epidemic. Comprehensive control strategies that combine preventive therapy for the most high-risk populations and communities with improved case-finding and treatment, control of transmission and health systems strengthening could ultimately lead to worldwide tuberculosis elimination. This paper outlines challenges to implementation of preventive therapy and provides pragmatic suggestions for overcoming them. It further advocates for tuberculosis preventive therapy as the core of a renewed global focus to implement a comprehensive epidemic control strategy that would reduce new tuberculosis cases to elimination targets. This strategy would be underpinned by accelerated research to further understand the biology of subclinical tuberculosis infections, develop novel diagnostics, and drug regimens specifically for subclinical tuberculosis infection, strengthen health systems, community engagement, and enhance sustainable large scale implementation of preventive therapy programs.

    Interferon-gamma release assays are widely used for the diagnosis of tuberculosis infection in Spain. However, there is no consensus on their application in specific clinical scenarios. To develop a guide-line for their use, a panel of experts comprising specialists in infectious diseases, respiratory diseases, microbiology, pediatrics and preventive medicine, together with a methodologist, conducted a systematic literature search, summarized the findings, rated the quality of the evidence, and formulated recommendations following the Grading of Recommendations of Assessment Development and Evaluations methodology. This document provides evidence-based guidance on the use of interferon-gamma release assays for the diagnosis of tuberculosis infection in patients at risk of tuberculosis or suspected of having active disease. The guidelines will be applicable to specialist and primary care, and public health. Copyright © 2016 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

    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.

    Full Text Available Background:intestinal parasitic infection is one of the most prevalent health problems in developing countries. This study was conducted to determine the prevalence of intestinal parasitic infection and its correlation with socio-demographic parameters in Haji-abad, 2015.MaterialsandMethods:This cross-sectional descriptive study was conducted on 635 samples. After completing questionnaires, stool samples were assessed macroscopically, and microscopically using direct slide smear with saline and lugol, formalin-ether concentration, Ziehl-Neelsen staining to track Cryptosporidium species and Trichrome staining for the samples suspected to amoeba and other indeterminate cases. PCR using specific primers was conducted for Entamoebahistolytica/E. dispar suspected samples. The results were analyzed using SPSSver.16 software.Results:Of total 635 samples, 198 cases (31.2% were infected by at least one intestinal parasite. The most common parasites in this area were: Blastocystis sp. (105, 16.5%, Endolimax nana (43, 6.8%, Entamoeba coli (32, 5.0%, Giardia lamblia (31, 4.9%, and Iodamoeba butschlii (11, 1.7%. Enterobius vermicularis (1, 0.2% was the only detected helminthic infection. Regarding socio-demographic variables, age, residence, sampling month, and job showed a significant correlation with IPIs (p-value=0.031, 0.019, 0.014, 0.012; respectively. None of nine microscopically suspected E. histolytica/E. dispar cases were confirmed by molecular investigations (PCR method and were considered as E. coli.Conclusion:In agreement with previous studies, helminthes infections show a dramatic decline compare to protozoa in this study. The relatively high incidence of intestinal protozoan infections in studies performed in Iran supports strategies for pre­venting the transmission and expansion of these parasites as a priority.

    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

    Private medical practitioners in Visakhapatnam district, Andhra Pradesh, India. To evaluate self-reported TB diagnostic and treatment practices amongst private medical practitioners against benchmark practices articulated in the International Standards of Tuberculosis Care (ISTC), and factors associated with compliance with ISTC. Cross- sectional survey using semi-structured interviews. Of 296 randomly selected private practitioners, 201 (68%) were assessed for compliance to ISTC diagnostic and treatment standards in TB management. Only 11 (6%) followed a combination of 6 diagnostic standards together and only 1 followed a combination of all seven treatment standards together. There were 28 (14%) private practitioners who complied with a combination of three core ISTC (cough for tuberculosis suspects, sputum smear examination and use of standardized treatment). Higher ISTC compliance was associated with caring for more than 20 TB patients annually, prior sensitization to TB control guidelines, and practice of alternate systems of medicine. Few private practitioners in Visakhapatnam, India reported TB diagnostic and treatment practices that met ISTC. Better engagement of the private sector is urgently required to improve TB management practices and to prevent diagnostic delay and drug resistance.

    Drug-resistant strains of tuberculosis (TB) represent a major threat to global TB control. In low- and middle-income countries, resource constraints make it difficult to identify and monitor cases of resistance using drug susceptibility testing and culture. Molecular assays such as the GeneXpert Mycobacterium tuberculosis/rifampicin may prove to be a cost-effective solution to this problem in these settings. The objective of this study is to evaluate the use of GeneXpert in the diagnosis of pulmonary TB since it was introduced into two tertiary hospitals in Ghana in 2013. A 2-year retrospective audit of clinical cases involving patients who presented with clinically suspected TB or documented TB not improving on standard therapy and had samples sent for GeneXpert testing. GeneXpert identified 169 cases of TB, including 17 cases of rifampicin-resistant TB. Of the seven cases with final culture and drug susceptibility testing results, six demonstrated further drug resistance and five of these were multidrug-resistant TB. These findings call for a scale-up of TB control in Ghana and provide evidence that the expansion of GeneXpert may be an optimal means to improve case finding and guide treatment of drug-resistant TB in this setting.

    The aim of this study was the detection of Aspergillus species and Mycobacterium tuberculosis together in bronchoalveolar lavage (BAL) using of multiplex PCR. In this study, from September 2012 until June 2013, 100 bronchoalveolar lavage (BAL) specimens were collected from patients suspected of tuberculosis (TB). After the direct and culture test, multiplex PCR were utilized in order to diagnose Aspergillus species and M. tuberculosis. Phenol-chloroform manual method was used in order to extract DNA from these microorganisms. Aspergillus specific primers, M. tuberculosis designed primers and beta actin primers were used for multiplex PCR. In this study, by multiplex PCR method, Aspergillus species were identified in 12 samples (12%), positive samples in direct and culture test were respectively 11% and 10%. Sensitivity and specificity of this method in comparison to direct test were respectively 100% and 98.8%, also sensitivity and specificity of this method in comparison to culture test were respectively 100% and 97.7%. In this assay, M. tuberculosis was identified in 8 samples (8%). Mycobacterium-positive samples in molecular method, direct and culture test were respectively 6%, 5% and 7%. Sensitivity and specificity of PCR method in comparison to direct test were 80% and 97.8% also sensitivity and specificity of this method in comparison to culture test was 71.4% and 98.9%. In the present study, multiplex PCR method had higher sensitivity than direct and culture test in order to identify and detect Aspergillus, also this method had lower sensitivity for identification of M. tuberculosis, suggesting that the method of DNA extraction was not suitable.

    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.

    Sternal wound infection with Mycobacterium tuberculosis is an uncommon yet highly challenging disease that can be quite insidious with various presentations. We hereby provide a review of 10 cases in current literature and describe an additional case which illustrates the difficulties associated with diagnosis. We used PubMed and Google search engine to search the literature for all published papers reporting on cases of sternal M. tuberculosis infections post open-heart surgeries. A total of 11 cases were presented, including a case of our own. The majority were males and were exposed to endemic areas. The average age was 59.6 ± 15.5 years. Coronary artery bypass surgery accounted for 73% of procedures and the average time to symptoms onset was 12.2 ± 16.6 months. Diabetes was the most reported non-cardiac comorbidity. Presenting symptoms varied and only 5 patients had other organs involved. Blood tests and radiographic studies were neither sensitive nor specific. M. tuberculosis culture on debrided tissues was the most sensitive test but often forgotten initially. Diagnostic delay was seen in almost all cases, often leading to unnecessary courses of antibiotics and aggressive surgical interventions. Finally, all patients responded well to anti-tuberculosis treatment, with reported treatment duration ranging from 9 to 12 months. M. tuberculosis infection of the sternum should be suspected in late-onset sternal wound infections post open-heart surgery especially when the course is chronic and indolent.

    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)

    Towards the end of the 19th century, Europe turned particular attention to the problem of tuberculosis, at that time the most serious social disease. In the majority of cases, pulmonary tuberculosis had a fatal outcome owing to the lack of effective drugs and methods of treatment. Due to poor sanitary conditions, particularly as regards dwellings, pulmonary tuberculosis was able to spread rapidly. Hospital departments were reluctant to admit patients suffering from tuberculosis. It was only after the discoveries of Robert Koch (bacillus tubercle in 1882) that the cause of the disease became understood and methods of treatment began to be developed. A modern sanatorium and hospital with 270 beds was erected in Hohenkrug (today Szczecin-Zdunowo) between 1915 and 1930. Patients could now be treated with modern methods, surgically in most cases. After the Second World War, pulmonary tuberculosis was still an enormous epidemiologic problem. In 1949, the Polish authorities opened a 400-bed sanatoriumin Zdunowo. The methods of treatment were not much different from pre-war practice and it was only the routine introduction of antituberculotic drugs during the fifties of the past century that brought about a radical change in the fight against tuberculosis. The growing numbers of patients with tuberculosis of the genitourinary system led to the opening in 1958 of a 40-bed specialist ward at the Tuberculosis Sanatorium in Zdunowo. It should be emphasized that the Department of Genitourinary Tuberculosis in Szczecin-Zdunowo was a historical necessity and a salvation for thousands of patients from Northern Poland. The Department totally fulfilled its social duties thanks to the commitment of many outstanding persons dedicated to helping the patients. This unit was finally closed in 1987 because the demand for surgical treatment of tuberculosis was declining concurrently with the advent of new and potent antituberculotics and falling number of new cases of genitourinary

    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

    2016-09-01

    Full Text Available Pyogenic liver abscess is an uncommon but important and potentially life-threatening disease that occurs whenever there is failure of clearance of an infection in the liver. Work presents a rare case of pyogenic liver abscess with confirmed bacterial aetiology of Staphylococcus aureus, subsequently confirmed Echinococcus multilocularis and suspected Mycobacterium tuberculosis liver infection in 6 years old child. Moreover, several other parasitic diseases were recorded. According to clinical presentation of diseases, it could be supposed that liver impairment caused by alveolar echinococcosis and potentially also by M. tuberculosis could be the predisposition site for the capture of Staphylococcus aureus in altered liver tissues during its haematogenous spreading, and thus contributed to the development and subsequent clinical presentation of pyogenic liver abscess. The presence of three different aetiological agents complicated the diagnostic process as well as the therapy of the patient and made her prognosis uncertain. Proper diagnosis of multiloculated liver abscesses, with echinococcosis and hepatic tuberculosis considered in the differential diagnosis, is therefore crucial to administration of early and appropriate treatment.

    Factors that influence testing for latent tuberculosis infection (LTBI) among foreign-born persons in Connecticut are not well understood. To identify predictors for LTBI testing and challenges related to accessing health care among the foreign-born population in Connecticut. Foreign-born Connecticut residents with confirmed or suspected tuberculosis (TB) disease during June 2005-December 2008 were interviewed regarding health care access and immigration status. Predictors for self-reported testing for LTBI after US entry were determined. Of 161 foreign-born persons interviewed, 48% experienced TB disease within 5 years after arrival. One third (51/156) reported having undergone post-arrival testing for LTBI. Although those with established health care providers were more likely to have reported testing (aOR 4.49, 95%CI 1.48-13.62), only 43% of such persons were tested. Undocumented persons, the majority of whom lacked a provider (53%), were less likely than documented persons to have reported testing (aOR 0.20, 95%CI 0.06-0.67). Hispanic permanent residents (immigrants and refugees) and visitors (persons admitted temporarily) were more likely than non-Hispanics in the respective groups to have reported testing (OR 5.25, 95%CI 1.51-18.31 and OR 7.08, 95%CI 1.30-38.44, respectively). The self-reported rate of testing for LTBI among foreign-born persons in Connecticut with confirmed or suspected TB was low and differed significantly by ethnicity and immigration status. Strategies are needed to improve health care access for foreign-born persons and expand testing for LTBI, especially among non-Hispanic and undocumented populations.

    Full Text Available BACKGROUND: The global tuberculosis epidemic results in nearly 2 million deaths and 9 million new cases of the disease a year. The vast majority of tuberculosis patients live in developing countries, where the diagnosis of tuberculosis relies on the identification of acid-fast bacilli on unprocessed sputum smears using conventional light microscopy. Microscopy has high specificity in tuberculosis-endemic countries, but modest sensitivity which varies among laboratories (range 20% to 80%. Moreover, the sensitivity is poor for paucibacillary disease (e.g., pediatric and HIV-associated tuberculosis. Thus, the development of rapid and accurate new diagnostic tools is imperative. Immune-based tests are potentially suitable for use in low-income countries as some test formats can be performed at the point of care without laboratory equipment. Currently, dozens of distinct commercial antibody detection tests are sold in developing countries. The question is "do they work?" METHODS AND FINDINGS: We conducted a systematic review to assess the accuracy of commercial antibody detection tests for the diagnosis of pulmonary tuberculosis. Studies from all countries using culture and/or microscopy smear for confirmation of pulmonary tuberculosis were eligible. Studies with fewer than 50 participants (25 patients and 25 control participants were excluded. In a comprehensive search, we identified 68 studies. The results demonstrate that (1 overall, commercial tests vary widely in performance; (2 sensitivity is higher in smear-positive than smear-negative samples; (3 in studies of smear-positive patients, Anda-TB IgG by enzyme-linked immunosorbent assay shows limited sensitivity (range 63% to 85% and inconsistent specificity (range 73% to 100%; (4 specificity is higher in healthy volunteers than in patients in whom tuberculosis disease is initially suspected and subsequently ruled out; and (5 there are insufficient data to determine the accuracy of most

    We report an extremely rare case of wandering spleen (WS) complicated with gastric volvulus and intestinal non-rotation in a male adult. A 22-year-old man who had been previously treated for Wilson disease was admitted with severe abdominal pain. Radiological findings showed WS in the midline of the pelvic area. The stomach was mesenteroaxially twisted and intestinal non-rotation was observed. Radiology results did not show any evidence of splenic or gastrointestinal (GI) infarction. Elective emergency laparoscopy confirmed WS and intestinal non-rotation; however, gastric volvulus was not observed. It was suspected that the stomach had untwisted when gastric and laparoscopic tubes were inserted. Surgery is strongly recommended for WS because of the high risk of serious complications; however, some asymptomatic adult patients are still treated conservatively, such as the patient in this study. The present case is reported with reference to the literature.

    AFB sputum and chest X-ray are used to identify patients with pulmonary TB. For extrapulmonary TB, fine needle aspiration cytology is needed, even though occasionally found not atypical feature in the form of eosinophilic material with dark brown particles, suspected as TB. This research was to show that eosinophilic material with dark brown particles is accurate as new criteria for the cytological diagnosis of TB. By performing fine needle aspiration biopsy stained with Giemsa, if an eosinophilic material with dark brown particles was encountered, we continued with Ziehl-Neelsen AFB stain and confirmed with PCR. To assess accuracy, we used a diagnostic test to evaluate sensitivity and specificity of eosinophilic material with dark brown particles by using AFB and PCR as the gold standard. The sensitivity and specificity of cytological diagnosis in tuberculosis of eosinophilic material with dark brown particles were 93.65% and 70.99%, respectively if confirmed with AFB. On the other hand, if confirmed with PCR using Mycobacterium tuberculosis DNA, the sensitivity and specificity were 98.95% and 96.79%, respectively. In conclusion, eosinophilic masses with dark brown particles is accurate as new criteria of TB diagnostic cytology with high sensitivity and specificity confirmed with AFB and PCR test.

    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)

    People concentrated in congregated systems, such as prisons, are important but often neglected reservoirs for TB transmission, and threaten those in the outside community. Therefore, this study was conducted to determine the prevalence of tuberculosis in a prison system of North Gondar Zone. An active case-finding survey in North Gondar Prison was carried out from March to May 2011. All prison inmates who had history of cough for at least a week were included in the study. Three morning sputum samples were collected from suspected inmates and examined through fluorescence microscopy. Fine needle aspiration cytology was done for those having significant lymphadenopathy. Pre and post HIV test counseling was provided after written consent. Binary logistic and multivariable analysis was performed using SPSS version 16. A total of 250 prisoners were included in the survey. Among these, 26 (10.4%) prisoners were found to have TB giving a point prevalence of 1482.3 per 100,000 populations of smear positive TB among the TB suspects. All the inmates who participated in the study volunteered for HIV testing and a total of 19(7.6%) inmates were found to be reactive for the HIV antibody test amongst of which 9(47.4%) had TB co-infection. The prevalence of HIV infection in the TB infected inmates was found to be 34.6% (9/26). From the 26 TB cases identified 12 (46.2%) were having under nutrition (BMI Prison with possible active transmission of TB within the prison. There was a high prevalence of HIV among the TB suspects. Strong cooperation between prison authorities and the national tuberculosis control programmes is urgently required to develop locally appropriate interventions to reduce transmission. The determinants for poor nutrition in the prison need also further investigation.

  18. Multidrug-resistant tuberculosis

    2008-01-01

    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

    Antonio Carlos Toledo Jr.

    Full Text Available This is a case report of a 29 year old male with pneumocystis pneumonia and tuberculosis, and who was initially suspected of having HIV infection, based on risk factor analyses, but was subsequently shown to be HIV negative. The patient arrived at the hospital with fever, cough, weight loss, loss of appetite, pallor, and arthralgia. In addition, he was jaundiced and had cervical lymphadenopathy and mild heptosplenomegaly. He had interstitial infiltrates of the lung, sputum smears positive for Mycobacterium tuberculosis and Pneumocystis carinii, and stool tests were positive for Strongyloides stercoralis and Schistosoma mansoni. He was diagnosed as having AIDS, and was treated for tuberculosis, pneumocystosis, and strongyloidiasis with a good response. The patient did not receive anti-retroviral therapy, pending outcome of the HIV tests. A month later, he was re-examined and found to have worsening hepatosplenomegaly, pancytopenia, fever, and continued weight loss. At this time, it was determined that his HIV ELISA antibody tests were negative. A bone marrow aspirate was done and revealed amastigotes of leishmania, and a bone marrow culture was positive for Leishmania species. He was treated with pentavalent antimony, 20 mg daily for 20 days, with complete remission of symptoms and weight gain. This case demonstrates that immunosuppression from leishmaniasis and tuberculosis may lead to pneumocystosis, and be misdiagnosed as HIV infection. The occurrence of opportunistic infections in severely ill patients without HIV must always be considered and alternate causes of immunosuppression sought.

    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.)

    Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB

    Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body. Two years later, multiple epidermoid cysts on the scalp were found. Since this patient was suspected to have Gardner syndrome, the authors recommended gastrointestinal endoscopy to check for intestinal polyposis. Gastrointestinal endoscopic examination revealed multiple polyposes in the upper gastrointestinal tract and fundus of the stomach. As a result, the final diagnosis was Gardner syndrome.

    Tuberculosis has been making havoc worldwide with an 11.9 million cases to be involved by the year 2005. In India, about 2 million cases are infected every year. Regarding triumphs and tragedies in the control of tuberculosis some points as follows are discussed. (1) Tuberculosis Control Programmes from National Tuberculosis Programme (NTP) to Revised National Tuberculosis Control Programme (RNTCP) and Directly Observed Treatment, Short course (DOTS). (2) Problem of multidrug resistance (MDR) tuberculosis and (3) HIV and tuberculosis. DOTS being largely based on Indian research. It is now being applied worldwide. MDR is strictly a man made problem. Poor prescriptions, poor case management, lack of coordinated education and haphazard treatment research result in drug resistance. Treatment of MDR is difficult. The drug acceptability, tolerance and toxicity have to be considered. HIV and tuberculosis form a deadly duo. They mean more cases, more costs and more national losses.

    Full Text Available SETTING: Private medical practitioners in Visakhapatnam district, Andhra Pradesh, India. OBJECTIVES: To evaluate self-reported TB diagnostic and treatment practices amongst private medical practitioners against benchmark practices articulated in the International Standards of Tuberculosis Care (ISTC, and factors associated with compliance with ISTC. DESIGN: Cross- sectional survey using semi-structured interviews. RESULTS: Of 296 randomly selected private practitioners, 201 (68% were assessed for compliance to ISTC diagnostic and treatment standards in TB management. Only 11 (6% followed a combination of 6 diagnostic standards together and only 1 followed a combination of all seven treatment standards together. There were 28 (14% private practitioners who complied with a combination of three core ISTC (cough for tuberculosis suspects, sputum smear examination and use of standardized treatment. Higher ISTC compliance was associated with caring for more than 20 TB patients annually, prior sensitization to TB control guidelines, and practice of alternate systems of medicine. CONCLUSION: Few private practitioners in Visakhapatnam, India reported TB diagnostic and treatment practices that met ISTC. Better engagement of the private sector is urgently required to improve TB management practices and to prevent diagnostic delay and drug resistance.

    Primary intestinal lymphangiectasia is a rare congenital disease described by Waldmann in 1961 that is a consequence of obstruction of the lymphatic drainage of the small bowel with secondary lymph vessel dilation. This distorts the architecture of the villi and causes a leakage of lymph into the intestinal lumen, resulting in protein-losing enteropathy and malabsorption. To describe the clinical, biochemical, radiologic, endoscopic, and histologic characteristics in children with primary intestinal lymphangiectasia. A retrospective observational, descriptive, cross-sectional study was conducted that reviewed the case records of children diagnosed with primary intestinal lymphangiectasia that were seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría within the time frame of January 1, 1992 to September 30, 2012. Four patients were found that presented with primary intestinal lymphangiectasia. Three of them had been diagnosed before 3 years of age. All the patients presented with chronic diarrhea, edema, lymphopenia, hypocalcemia, and hypogammaglobulinemia, and 3 patients presented with hypocholesterolemia. Bowel transit time, endoscopy, and intestinal biopsies were characteristic of this pathology. 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. Copyright © 2013 Asociación Mexicana de Gastroenterología. Published by Masson Doyma México S.A.

    INTRODUCTION Health care workers have an increased risk of infection due to occupational Mycobacterium tuberculosis exposure, including multidrug-resistant strains. Health care workers' risk of developing tuberculosis is greater than that of the general population, whether in low-, intermediate- or high-incidence countries. Adherence to infection control measures (administrative controls, environmental controls, and personal respiratory protection) is essential to reduce risk of disease transmission between suspected tuberculosis patients and health care workers, but for different reasons, both objective and subjective, adherence is low. Identifying the causes of low adherence is a prerequisite to effective programming to reduce risk. OBJECTIVE Identify perceived barriers to adherence to tuberculosis infection control measures among health care workers in the Dominican Republic. METHODS During August 2014, a qualitative study was conducted in two tertiary-level hospitals in different regions of the Dominican Republic. A semi-structured interview guide of nine questions was developed, based on the scientific literature and with consensus of clinical experts. Nine semi-structured interviews were conducted with a purposive sample of seven physicians (five men, two women) and two baccalaureate nurses (both women) working in the emergency medicine, internal medicine or nursing departments of those institutions. Question topics included clinical experience of M. tuberculosis infection and disease; knowledge of disease transmission and preventive practices; clinical management strategies; and perceptions of effectiveness of directly observed treatment, short-course, and disease coping strategies. RESULTS Perceived barriers were described as: 1) sense of invincibility of health care workers; 2) personal beliefs of health care workers related to direct patient communication; 3) low provider-to-patient ratios in hospitals; 4) absence of tuberculosis isolation units for

    The aim of this study is to record the observations and experience on the diagnosis and management of abdominal tuberculosis (TB) and to highlight the difficulties in the diagnosis and management of this condition. Two hundred consecutive patients attending the Gastroenterology Department of the King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia between May 1991 and May 2001, suspected with abdominal TB were investigated. A detailed clinical history and physical examination were obtained. Data of 75 confirmed cases of abdominal TB were analyzed. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%). Abdominal tenderness was the most common clinical finding, followed by ascites and abdominal mass (42%). The chest radiograph suggestive of pulmonary TB was diagnosed in 24 patients (32%). Computed tomographic (CT) scanning revealed abnormalities in all 51 patients who underwent the procedure, while positive findings were observed by abdominal ultrasound in 66% of the tested patients. Histopathological examination of patients showed tuberculosis granuloma, while acid fast bacilli were seen in 34%. Mycobacterium tuberculosis was identified by microbiological methods in 60% of patients. The most common presenting symptoms were anorexia (84%), abdominal pain (84%) and weight loss (72%).

    Full Text Available Background and objective: There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV co-infection in a national referral hospital in Phnom Penh, Cambodia. Design: Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. Results: M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB. The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (p<0.001. The diagnosis of MDR TB was made after death in 15.8% of patients; in total 26.3% of patients with MDR TB died. The diagnosis of TB was established by culture of extra-pulmonary specimens in 23.6% of cases. Conclusions: There is significant resistance to first-line TB drugs amongst new and previously treated TB–HIV co-infected patients in Phnom Penh. These data suggest that the prevalence of DR TB in Cambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

    Full Text Available Abstract Background Although tuberculosis is not uncommon among patients with myelodysplastic syndrome (MDS, only a few reports of such patients suffering from miliary tuberculosis (MT exist. MT often presents as a fever of unknown origin and it is a curable disease, yet fatal if left untreated. Case presentation We report a case of MT with no clinical or laboratory indications of pulmonary involvement in a patient with MDS, and review the relevant literature. Mycobacterium tuberculosis was isolated from the liquid culture of a bone marrow aspirate. Conclusion Even if the initial diagnostic investigation for a fever of obscure etiology is negative, MT should not be excluded from the differential diagnosis list. Since it is a curable disease, persistent and vigorous diagnostic efforts are warranted. In suspected cases, mycobacterial blood cultures should be collected as soon as possible after hospital admission and early bone marrow aspirate with mycobacterial cultures is advocated.

    Pulmonary nocardiosis mimic pulmonary tuberculosis in most clinical and radiological manifestations. In Tanzania, where tuberculosis is one of the major public health threat clinical impact of nocardiosis as the cause of the human disease remains unknown. The objective of the present study was to isolate and identify Nocardia isolates recovered from TB suspects in Northeastern, Tanzania by using biochemical and molecular methods. The study involved 744 sputum samples collected from 372 TB suspects from four periphery diagnostic centers in Northeastern, Tanzania. Twenty patients were diagnosed as having presumptively Nocardia infections based on microscopic, cultural characteristics and biomèrieux ID 32C Yeast Identification system and confirmed using 16S rRNA and hsp65 gene specific primers for Nocardia species and sequencing. Biochemically, the majority of the isolates were N. asteroides (n = 8/20, 40%), N. brasiliensis (n = 4/20, 20%), N. farcinica (n = 3/20, 15%), N. nova (n = 1/20, 5%). Other aerobic actinomycetales included Streptomyces cyanescens (n = 2/20, 10%), Streptomyces griseus, Actinomadura madurae each (n = 1/20, 5%). Results of 16S rRNA and hsp65 sequencing were concordant in 15/17 (88. 2%) isolates and discordant in 2/17 (11.8%) isolates. Majority of the isolates belonged to N. cyriacigeorgica and N. farcinica, four (23.5%) each. Our findings suggest that Nocardia species may be an important cause of pulmonary nocardiosis that is underdiagnosed or ignored. This underscores needs to consider pulmonary nocardiosis as a differential diagnosis when there is a failure of anti-TB therapy and as a possible cause of human infections.

    The only available data about tuberculosis (TB) among adolescents date back to the 1980s, although the incidence of tuberculosis has been increasing in this age group. Medical records were reviewed for all adolescents aged 12 to 18 years hospitalized with the diagnosis of TB in Avicenne/Jean Verdier Teaching hospital (Seine-Saint-Denis, suburb of Paris) between September 2000 and December 2004. Of the 52 patients identified, 52% were female. Median age at diagnosis was 15 years (range, 12-18 years). The proportion of adolescents known to be born abroad was 90%. Diagnoses resulted from the examination of a sick child in 79% of cases, a case contact investigation of an adult suspected of having TB in 19% and routine tuberculin skin test in 2%. Twenty-seven of 52 patients (52%) had isolated pulmonary disease. Sixteen patients (31%) had pulmonary and extrapulmonary TB and 8 cases (17%) had exclusively extrapulmonary disease. The site of extrapulmonary TB included pleural (n = 8), meningitis (n = 4), lymph node (n = 4), peritoneal (n = 5), osteoarticular (n = 3) and genitourinary (n = 1). TB was confirmed by the isolation of Mycobacterium tuberculosis from sputum (n = 21), gastric aspirate (n = 8), bone (n = 1) or cerebrospinal fluid (n = 2). No case had a relapse or recurrence of disease in median 3.2 years of follow up. Our results indicate that demographic and clinical characteristics of adolescents with TB differed from adults and children. A specific approach to the prevention and treatment of TB in adolescents is absolutely necessary.

METHODS: Reviewed articles were identified by searching Pubmed for the terms "smoking" or "tobacco" and "tuberculosis". Additional articles were obtained from the bibliographies of identified papers. RESULTS: Thirty-four studies were reviewed: five investigate the association between smoking and mortality from tuberculosis, 13 investigate the association between smoking and development of tuberculosis, eigth investigate the association between smoking and infection with Mycobacterium tuberculosis, and nine estimate the impact of smoking on characteristics of tuberculosis and disease outcomes. CONCLUSIONS: Taken together, evidence suggests that smoking (both current and former is associated with: risk of being infected with Mycobacterium tuberculosis, risk of developing tuberculosis, development of more severe forms of tuberculosis, and risk of dying of tuberculosis. In many cases, there is a strong dose-response relationship -both in terms of quantity and duration of smoking. These relationships are not explained away by controlling for potentially confounding variables such as age, gender, alcohol consumption, and HIV status.OBJETIVO: Revisar evidencia epidemiológica relativa a la asociación entre el tabaquismo y la tuberculosis.

    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.

    Rapid and sensitive detection of Mycobacterium tuberculosis complex (MTB) directly on clinical respiratory specimens is essential for a correct management of patients suspected of tuberculosis. For this purpose PCR-based kits are available to detect MTB in respiratory specimen but most of them need at least 4 hours to be completed. New methods, based on TRC method (TRC: Transcription Reverse transcription Concerted--TRCRapid M. Tuberculosis--Tosoh Bioscience, Tokyo, Japon) and dedicated monitor have been developed. A new kit (TRC Rapid M. tuberculosis and Real-time monitor TRCRapid-160, Tosoh Corporation, Japan) enabling one step amplification and real-time detection of MTB 16S rRNA by a combination of intercalative dye oxazole yellow-linked DNA probe and isothermal RNA amplification directly on respiratory specimens has been tested in our laboratory. 319 respiratory specimens were tested in this preliminary study and results were compared to smear and culture. Fourteen had a positive culture for MTB. Among theses samples, smear was positive in 11 cases (78.6%) and TRC process was positive in 8 cases (57.1%). Overall sensitivity of TRC compared to smear positive samples is 73%. Theses first results demonstrated that a rapid identification of MTB was possible (less than 2 processing hours for 14 specimens and about 1 hour for 1 specimen) in most cases of smear positive samples using ready to use reagents for real time detection of MTB rRNA in clinical samples. New pretreatment and extraction reagents kits to increase the stability of the sputum RNA and the extraction efficiency are now tested in our laboratory.

FDG DHTC found the positive primary lung lesions in 37 of 38 patients with lung cancer, and was negative in 1 squamous cell carcinoma patient who had a atelectasis whose lesion size was 12 mm in diameter. FDG DHTC found false positive in 16 of 72 patients with benign diseases (14 with tuberculosis and 2 with inflammation). The sensitivity, specificity and accuracy of FDG DHTC in detecting lung cancer in patients with suspected malignant pleural effusion or malignant atelectasis were 97%, 78% and 85%, respectively. 30 patients with lung cancer and a pleural effusion, FDG DHTC correctly detected the presence of malignant pleural effusion and malignant pleural involvement in 18 of 21 patients and excluded malignant pleural effusion or pleural metastatic involvement in 8 of 9 patients (sensitivity, specificity and accuracy of 86%, 89% and 87% respectively). The mediastinal lymph node metastasis was found in 6 of these 21 patients with malignant pleural effusions. Conclusions: FDG DHTC imaging is a highly accurate and reliable noninvasive test in finding primary lung malignant lesions in patients with pleural effusion or atelectasis on CT scanning. Active tuberculosis or tuberculo-pleurisy is the main reason of false positivity on FDG DHTC imaging. FDG DHTC is also useful to differentiate malignant from benign pleural effusion in patients with lung cancer. (authors)

    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.

    We herein report a case of Addison's disease caused by tuberculosis characterized by atypical hyperpigmentation, noted as exacerbation of the pigmentation of freckles and the occurrence of new freckles, that was diagnosed in the presence of active pulmonary tuberculosis. The clinical condition of the patient was markedly ameliorated by the administration of hydrocortisone and anti-tuberculosis agents. When exacerbation of the pigmentation of the freckles and/or the occurrence of new freckles are noted, Addison's disease should be considered as part of the differential diagnosis. In addition, the presence of active tuberculosis needs to be assumed whenever we treat patients with Addison's disease caused by tuberculosis, despite its rarity.

    2012-12-15

    Despite the burden of both malnutrition and tuberculosis in children worldwide, there are few studies on the mechanisms that underlie this relationship. From available research, it appears that malnutrition is a predictor of tuberculosis disease and is associated with worse outcomes. This is supported through several lines of evidence, including the role of vitamin D receptor genotypes, malnutrition's effects on immune development, respiratory infections among malnourished children, and limited work specifically on pediatric tuberculosis and malnutrition. Nutritional supplementation has yet to suggest significant benefits on the course of tuberculosis in children. There is a critical need for research on childhood tuberculosis, specifically on how nutritional status affects the risk and progression of tuberculosis and whether nutritional supplementation improves clinical outcomes or prevents disease.

    Our understanding of mechanisms underlying progression from Mycobacterium tuberculosis infection to pulmonary tuberculosis disease in humans remains limited. To define such mechanisms, we followed M. tuberculosis-infected adolescents longitudinally. Blood samples from forty-four adolescents who ultimately developed tuberculosis disease (“progressors”) were compared with those from 106 matched controls, who remained healthy during two years of follow up. We performed longitudinal whole blood transcriptomic analyses by RNA sequencing and plasma proteome analyses using multiplexed slow off-rate modified DNA aptamers. Tuberculosis progression was associated with sequential modulation of immunological processes. Type I/II interferon signalling and complement cascade were elevated 18 months before tuberculosis disease diagnosis, while changes in myeloid inflammation, lymphoid, monocyte and neutrophil gene modules occurred more proximally to tuberculosis disease. Analysis of gene expression in purified T cells also revealed early suppression of Th17 responses in progressors, relative to M. tuberculosis-infected controls. This was confirmed in an independent adult cohort who received BCG re-vaccination; transcript expression of interferon response genes in blood prior to BCG administration was associated with suppression of IL-17 expression by BCG-specific CD4 T cells 3 weeks post-vaccination. Our findings provide a timeline to the different immunological stages of disease progression which comprise sequential inflammatory dynamics and immune alterations that precede disease manifestations and diagnosis of tuberculosis disease. These findings have important implications for developing diagnostics, vaccination and host-directed therapies for tuberculosis. Clincialtrials.gov, NCT01119521.

    To describe the outcome of neonates with prenatal intestinal volvulus. All neonates with prenatal intestinal volvulus managed in our institution between May 2004 and December 2010 were retrospectively studied. All neonates with prenatal or neonatal diagnosis of prenatal intestinal volvulus were included. We analyzed age at diagnosis, fetal ultrasound (US) scan and magnetic resonance imaging (MRI) findings, clinical signs at birth, surgical findings, management, and postoperative outcome. Ten neonates with prenatal intestinal volvulus were identified. Prenatal US scans or MRI demonstrated evidence of meconium peritonitis in one fetus and bowel dilatation in 2 others. The mean gestational age at birth was 36 weeks (range, 31-38 weeks) and the mean birth weight was 2811g (range, 2050-3700g). One premature neonate developed respiratory distress and required ventilatory support at birth. In 7 neonates, clinical examination showed distended abdomen and emesis, whereas plain abdominal radiographs showed intestinal obstruction. All neonates underwent surgery and all had normal intestinal rotation, except one with total intestinal volvulus secondary to malrotation. Other causes of volvulus were suspected in 4 neonates: mesenteric defect (n=1), intestinal atresia (n=2) and narrow mesentery (n=1). Detorsion of total volvulus, ileostomy, or intestinal resection with primary anastomosis was performed in 2, 5, and 3 neonates, respectively. One patient with total intestinal volvulus secondary to malrotation died, whereas all other neonates survived. In one patient, the postoperative course was complicated by intestinal dysmotility of the distal small bowel requiring a secondary jejunoileostomy. Stoma closure was subsequently performed at 1 year of age with good outcome. One patient developed angiocholitis treated successfully with antibiotics. Median time to initiate enteral feeds was 7 days (range, 4-16 days) and all patients were subsequently weaned from parenteral nutrition

    Tuberculosis (TB) hospital in Mumbai, India. To describe the mobility patterns of persons with suspected drug-resistant tuberculosis (DR-TB) and to assess whether there were significant differences in demographic or risk characteristics based on mobility. Observational cohort study of TB clinic patients at risk for DR-TB. Among 602 participants, 37% had ever moved from their place of birth; 14% were local movers (within state), and 23% were distant movers, between states or countries. Univariate multinomial logistic regression models showed that distant movers were more likely than non-movers to have lower income, less education, a greater number of previous TB episodes, and to have ever smoked. Compared to non-movers, local movers were more likely to have lower income and were more likely to have seen a doctor in the past 2 years. Clinical outcomes, including DR-TB, diabetes, and human immunodeficiency virus (HIV), did not differ between the three mobility groups. Mobility was common among patients at risk for DR-TB in Mumbai. TB programs should consider the implications of mobility on the protracted treatment for DR-TB in India.

    To evaluate the usefulness of MR imaging for diseases of the small intestine, emphasizing a comparison with CT. Thirty-four patients who underwent both CT and MR imaging using FLASH 2D and HASTE sequences were analyzed. All patients had various small bowel diseases with variable association of peritoneal lesions. We compared the detectabilities of CT and MR imaging using different MR pulse sequences. The capability for analyzing the characteristics of small intestinal disease was also compared. MR imaging was nearly equal to CT for detecting intraluminal or peritoneal masses, lesions in the bowel and mesentery, and small bowel obstruction, but was definitely inferior for detecting omental lesions. The most successful MR imaging sequence was HASTE for demonstrating bowel wall thickening, coronal FLASH 2D for mesenteric lesions, and axial FLASH 2D for omental lesions. MR imaging yielded greater information than CT in six of 12 inflammatory bowel diseases, while it was equal to CT in six of seven neoplasms and inferior in five of seven mesenteric ischemia. In determining the primary causes of 15 intestinal obstructions, MR imaging was correct in 11 (73%) and CT in nine (60%) patients. MR imaging can serve as an alternative diagnostic tool for patients with suspected inflammatory bowel disease, small intestinal neoplasm or obstruction.

    Although intestinal parasitic infections rarely cause acute appendicitis, they are common public health problems in undeveloped and developing countries. Parasitic infections should be kept in mind in patients clinically suspected of having acute appendicitis, and treatment procedures should be adopted according to the etiology. Herein we presented the cases of four patients with clinical findings of acute appendicitis. Patients were clinically suspected of having acute appendicitis, and Enterobius vermicularis was detected in the pathological examinations of specimens. Pinworm infections are common parasitic infections that may mimic appendicitis. The pathology of the four cases was noted when the file of 186 patients aged between 4 and 72 years who underwent surgery for acute appendicitis in my hospital was retrospectively reviewed. When the appendectomy specimen was examined histopathologically it was understood that acute appendicitis was caused by Enterobius vermicularis parasite. In Enterobius infections, performing systemic therapy for patients and their family members is sufficient. To prevent unnecessary appendectomy, this type of infection should be made to ask in the history and clinical findings of patients.

    Full Text Available Avian tuberculosis diagnosis was made in captive wild birds (Burhinus bistriatus and Porphyrula martinica from a zoo park at Sabana de Bogotá (Colombia. Based on this diagnosis, a surveillance approach was designed in order to demonstrate whether or not a focus of tuberculosis infection caused by Micobacterium avium was present at this zoo with the purpose to identify a possible hazard to prevent the infection of other bird population, visitors and workers of the park. Clinical, morphological (gross and microscopic are described in this article, but microbiological (culture in specific media, epidemiological (DPP and molecular (PCR studies, will be shown in other journal. In this work animals were organized en three different groups as follow: Five Hy line Brown chicken tuberculosis free coming from a commercial farm (sentinel group. A mixed group birds (102 animals from the pens around the primary focus (28 dukes, 25 “guacamayas”, 26 parrots and 23 rapacious birds, (highest risk group. Five birds within the pen in which the diagnosis was made (contaminated birds group. It was demonstrated granulomatous lesions in animals from the sentinel group as well as in those from the pen in which the first diagnosis was made. Lesions were founded in liver, spleen, lungs, kidneys, intestines and in one case in the white matter and leptomeniges of the spinal cord were affected. Ziehl – Neelsen positive rods were identified in all the affected tissues. No tuberculosis lesions were found in animals caged in neighborhood pens. It was concluded that there is an infectious focus of tuberculosis (micobacteriosis caused by M. avium in the zoo, but the focus is located only in one pen and this focus could represent a critical risk of infection with M. avium for some of the birds within the zoo, wild and eventually commercials birds and the human beings as well. It is recommended that prevention, control and eradication measurements have to be made to prevent

    Although the discovery of effective anti-tuberculosis drugs has made uncomplicated spinal tuberculosis a medical disease, the advent of multi-drug-resistant Mycobacterium tuberculosis and the co-infection of HIV with tuberculosis have led to a resurgence of the disease recently. The principles of drug treatment of spinal tuberculosis are derived from our experience in treating pulmonary tuberculosis. Spinal tuberculosis is classified to be a severe form of extrapulmonary tuberculosis and hence is included in Category I of the WHO classification. The tuberculosis bacilli isolated from patients are of four different types with different growth kinetics and metabolic characteristics. Hence multiple drugs, which act on the different groups of the mycobacteria, are included in each anti-tuberculosis drug regimen. Prolonged and uninterrupted chemotherapy (which may be 'short course' and 'intermittent' but preferably 'directly observed') is effective in controlling the infection. Spinal Multi-drug-resistant TB and spinal TB in HIV-positive patients present unique problems in management and have much poorer prognosis. Failure of chemotherapy and emergence of drug resistance are frequent due to the failure of compliance hence all efforts must be made to improve patient compliance to the prescribed drug regimen.

    Current study evaluated the hsp65 Nested PCR Restriction Fragment Length Polymorphism Analysis (hsp65 Nested PCR-PRA) to detect and identify Mycobacterium tuberculosis complex directly in clinical samples for a rapid and specific diagnosis of tuberculosis (TB). hsp65 Nested PCR-PRA was applied directly to 218 clinical samples obtained from 127 patients suspected of TB or another mycobacterial infection from July 2009 to July 2010. The hsp65 Nested PCR-PRA showed 100% sensitivity and 95.0 and 93.1% specificity in comparison with culture and microscopy (acid fast bacillus smear), respectively. hsp65 Nested PCR-PRA was shown to be a fast and reliable assay for diagnosing TB, which may contribute towards a fast diagnosis that could help the selection of appropriate chemotherapeutic and early epidemiological management of the cases which are of paramount importance in a high TB burden country.

    Intestinal malrotation is a congenital anomaly of the intestinal rotation and fixation, and usually occurs in the neonatal age. Description of a clinical case associated with acute occlusive symptoms. A case of intestinal malrotation is presented in a previously asymptomatic woman of 46 years old with an intestinal obstruction, with radiology and surgical findings showing an absence of intestinal rotation. Intestinal malrotation in adults is often asymptomatic, and is diagnosed as a casual finding during a radiological examination performed for other reasons. Infrequently, it can be diagnosed in adults, associated with an acute abdomen. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    Pulmonary tuberculosis is occasionally confused with invasive pulmonary aspergillosis (IPA) in transplant recipients, since clinical suspicion and early diagnosis of pulmonary tuberculosis and IPA rely heavily on imaging modes such as computed tomography (CT). We therefore investigated IPA-mimicking tuberculosis in transplant recipients. All adult transplant recipients who developed tuberculosis or IPA at a tertiary hospital in an intermediate tuberculosis-burden country during a 6-year period were enrolled. First, we tested whether experienced radiologists could differentiate pulmonary tuberculosis from IPA. Second, we determined which radiologic findings could help us differentiate them. During the study period, 28 transplant recipients developed pulmonary tuberculosis after transplantation, and 80 patients developed IPA after transplantation. Two experienced radiologists scored blindly 28 tuberculosis and 50 randomly selected IPA cases. The sensitivities of radiologists A and B for IPA were 78% and 68%, respectively (poor agreement, kappa value = 0.25). The sensitivities of radiologists A and B for tuberculosis were 64% and 61%, respectively (excellent agreement, kappa value = 0.77). We then compared the CT findings of the 28 patients with tuberculosis and 80 patients with IPA. Infarct-shaped consolidations and smooth bronchial wall thickening were more frequent in IPA, and mass-shaped consolidations and centrilobular nodules (tuberculosis. Certain CT findings appear to be helpful in differentiating between IPA and tuberculosis. Nevertheless, the CT findings of about one-third of pulmonary tuberculosis cases in transplant recipients are very close to those of IPA. © The Author 2015.

    Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB), is becoming increasingly recognized as an important cause of fatal chronic illnesses in China. In this study, we report an infectious disease among 84 rhesus macaques at a Chinese zoo. Their clinical signs and symptoms were very similar with the manifestations of TB in humans. To determine the potential pathogens of this outbreak, many methods were used. First, tuberculin skin tests showed that none of the monkeys displayed significant skin reactions. Subsequently, the sera were tested for specific antibody IgG; 29 (34.5%) and 39 (46.4%) blood samples tested positive by TB-IgG and TB-DOT, respectively. Radiographic examination showed characteristic imageology changes in 14 (16.7%) monkeys. One individual determined as positive by the above three methods was euthanized, and histopathological analysis demonstrated typical granulomas and caseous necrosis in the lung, liver, spleen, and intestine. Furthermore, the pathogenic mycobacteria were isolated from lung lobe, cultured on acidic Lowenstein-Jensen culture medium, and identified as M. tuberculosis by real-time PCR and DNA sequencing. Nevertheless, the origin of the infection remained unknown. These findings emphasize the need to strengthen the management and training of staff, especially those working at animal shelters.

    2007-01-01

    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.

    The study was designed to compare immune responses to Mycobacterium tuberculosis bacilli and antigens in healthy Portuguese subjects and pulmonary tuberculosis patients (TB), and to correlate immune status with clinical severity of tuberculosis disease. PBMC were cultured and stimulated with live and killed M. tuberculosis H37Rv and purified protein derivative (PPD) and lymphoproliferation and production of IFN-gamma and IL-5/IL-4 by these cultures were evaluated by the use of ELISA and multi-parameter flow cytometry. PBMC from 30 tuberculosis patients demonstrated significantly reduced amounts of proliferation and IFN-gamma when stimulated with live M. tuberculosis compared the control group. Of 15 tuberculosis patients tested for intracellular IL-4 following stimulation with M. tuberculosis, 7 showed greatly increased IL-4 production in CD8+ and gammadelta+ T cells. Tuberculosis patients demonstrated an increase of intracellular IL-4 after PBMC were stimulated with live M. tuberculosis in the CD4+ phenotype, but more notably in CD8+ and gammadelta TCR+ subsets. Increased production of IL-4 in tuberculosis patients was primarily in individuals with advanced involvement of lung parenchymal with high bacterial loads in sputum. These results suggest that an alteration in type 1 and type 2 cytokine balance can occur in patients with tuberculosis at an advanced clinical stage of disease.

    By the summer of 2014, the Syrian crisis resulted in a regional humanitarian emergency with 2.9 million refugees, including 608,000 in Jordan. These refugees access United Nations High Commissioner for Refugees (UNHCR)-sponsored clinics or Jordan Ministry of Health clinics, including tuberculosis diagnosis and treatment. Tuberculosis care in Syria has deteriorated with destroyed health infrastructure and drug supply chain. Syrian refugees may have undiagnosed tuberculosis; therefore, the UNHCR, the International Organization for Migration (IOM), the National Tuberculosis Program (NTP), and the Centers for Disease Control and Prevention developed the Public Health Strategy for Tuberculosis among Syrian Refugees in Jordan. This case study presents that strategy, its impact, and recommendations for other neighboring countries. UNHCR determined that World Health Organization (WHO) criteria for implementing a tuberculosis program in an emergency were met for the Syrian refugees in Jordan. Jordan NTP assessed their tuberculosis program and found that access to Syrian refugees was the one component of their program missing. Therefore, a strategy for tuberculosis control among Syrian refugees was developed. Since that development through work with IOM, UNHCR, and NTP, tuberculosis case detection among Syrian refugees is almost 40 % greater (74 cases/12 months or 1.01/100,000 monthly through June 2014 vs. 56 cases/16 months or 0.73/100,000 monthly through June 2013) using estimated population figures; more than two fold the 2012 Jordan tuberculosis incidence. Additionally, the WHO objective of curing ≥85 % of newly identified infectious tuberculosis cases was met among Syrian refugees. Tuberculosis (TB) rates among displaced persons are high, but increased detection is possible. High TB rates were found among Syrian refugees through active screening and will probably persist as the Syrian crisis continues. Active screening can detect tuberculosis early and reduce risk

    The aim of this study was to evaluate the efficiency of four isolation methods for the detection of pathogenic Yersinia enterocolitica from pig intestinal content. The four methods comprised of 15 isolation steps using selective enrichments (irgasan-ticarcillin-potassium chlorate and modified Rappaport broth) and mildly selective enrichments at 4 or 25 degrees C. Salmonella-Shigella-desoxycholate-calcium chloride agar, cefsulodin-irgasan-novobiocin agar were used as plating media. The most sensitive method detected 78% (53/68) of the positive samples. Individual isolation steps using cold enrichment as the only enrichment or as a pre-enrichment step with further selective enrichment showed the highest sensitivities (55-66%). All isolation methods resulted in high numbers of suspected colonies not confirmed as pathogenic Y. enterocolitica. Cold enrichment should be used in the detection of pathogenic Y. enterocolitica from pig intestinal contents. In addition, more than one parallel isolation step is needed. The study shows that depending on the isolation method used for Y. enterocolitica, the detected prevalence of Y. enterocolitica in pig intestinal contents varies greatly. More selective and sensitive isolation methods need to be developed for pathogenic Y. enterocolitica.

    Full Text Available Tuberculosis is a major health concern in prisons, particularly where HIV prevalence is high. Our objective was to determine the undiagnosed pulmonary tuberculosis ("undiagnosed tuberculosis" prevalence in a representative sample of prisoners in a South African prison. In addition we investigated risk factors for undiagnosed tuberculosis, to explore if screening strategies could be targeted to high risk groups, and, the performance of screening tools for tuberculosis.In this cross-sectional survey, male prisoners were screened for tuberculosis using symptoms, chest radiograph (CXR and two spot sputum specimens for microscopy and culture. Anonymised HIV antibody testing was performed on urine specimens. The sensitivity, specificity and predictive values of symptoms and investigations were calculated, using Mycobacterium tuberculosis isolated on sputum culture as the gold standard. From September 2009 to October 2010, 1046 male prisoners were offered enrolment to the study. A total of 981 (93.8% consented (median age was 32 years; interquartile range [IQR] 27-37 years and were screened for tuberculosis. Among 968 not taking tuberculosis treatment and with sputum culture results, 34 (3.5%; 95% confidence interval [CI] 2.4-4.9% were culture positive for Mycobacterium tuberculosis. HIV prevalence was 25.3% (242/957; 95% CI 22.6-28.2%. Positive HIV status (adjusted odds ratio [aOR] 2.0; 95% CI 1.0-4.2 and being an ex-smoker (aOR 2.6; 95% CI 1.2-5.9 were independently associated with undiagnosed tuberculosis. Compared to the gold standard of positive sputum culture, cough of any duration had a sensitivity of 35.3% and specificity of 79.6%. CXR was the most sensitive single screening modality (sensitivity 70.6%, specificity 92.2%. Adding CXR to cough of any duration gave a tool with sensitivity of 79.4% and specificity of 73.8%.Undiagnosed tuberculosis and HIV prevalence was high in this prison, justifying routine screening for tuberculosis at entry

    In the developed countries gastrointestinal tuberculosis is no longer common in clinical practice. In this setting the importance of the condition lies in the vagaries of its presentation and the fact that it is eminently treatable, usually by a combination of chemotherapy and surgery. The clinical features and complications of gastrointestinal tuberculosis are highlighted by the seven cases which we report. Diagnosis and treatment of this condition is discussed and attention is drawn to the importance of case notification. Clinicians should bear in mind the diagnosis of gastrointestinal tuberculosis when dealing with any patient with non-specific abdominal symptoms.

    Full Text Available Introduction. Incidence of gastroschisis (GS complicated by intestinal atresia is 4.5–12.6% of cases. 80% of this obstructions are observed in jejunoileal segment. Association of GS with intestinal atresia (GIA is usually diagnosed well, but at birth, diagnosis of atresia is often controversial. There is misdiagnosis of atresia during the initial surgery in about 12% of cases. The ideal treatment model of GIA had not already been set. Different surgical approaches were described in literature: abdominal closure modalities, terms of intestinal anastomoses creation and intestinal stomas formation remain outstanding issues. the severity of congenital defects may vary thus the tactics and strategy of surgical management as well as the ability to create primary intestinal anastomosis should be considered individually. Clinical case. GS with severe viscero-abdominal disproportion (VAD in fetus was diagnosed prenatally by ultrasonography (US at 21 week of gestation. Prenatal US follow-up monitoring and examinations were conducted. The presence of concomitant intestinal obstruction was suspected at 35 week of gestation. Regarding diagnosed malformations, according to developed in our clinic "First Minutes Surgery" tactics, operation was performed in 15 minutes after birth. During the initial surgery intestinal obstruction was not confirmed. Staged surgical management of GS was conducted. Intestinal obstruction was diagnosed and confirmed by radiography only after 21 days of age, after increasing of oral intakes volume to 15.0 ml. Jejunal web was found on surgery. Following web removal diamond-shaped anastomosis was created. During post-op period the recurrence of intestinal obstruction was not observed, full enteral nutrition was reached. The good outcome after exhibited surgical management was achieved. Conclusions. The proposed strategy and tactics of surgical management found to be effective and can be applied in the case of GS with severe VAD

The purpose of this study was to identify whether an association exists between latent tuberculosis infection (LTBI) and intestinal parasite infection among newly resettled refugees in Texas while controlling for additional effects of region of origin, age and sex. Data for all refugees screened for both TB and intestinal parasites between January 2010 and mid-October 2013 were obtained from the Texas Refugee Health Screening Program and were analyzed using logistic regression. A total of 9860 refugees were included. In multivariable logistic regression analysis, pathogenic and non-pathogenic intestinal parasite infections yielded statistically significant reduced odds of LTBI. However, when individual parasite species were analyzed, hookworm infection indicated statistically significant increased odds of LTBI (OR 1.674, CI: 1.126-2.488). A positive association exists between hookworm infection and LTBI in newly arrived refugees to Texas. More research is needed to assess the nature and extent of these associations. © The Author 2015.

    Full Text Available Some diseases have played a more significant role in human development than others. Here we describe the results of a trial to diagnose ancient tuberculosis using chemical methods. Palaeo-epidemiological studies of the disease are compromised, but it has become apparent that tuberculosis (TB is a 'population-density dependent' disease. From modern studies, it is also apparent that the prevalence of TB can be used as an indicator of the level of poverty within the studied population. Mid-shaft rib samples from articulated individuals recovered from the former Newcastle Infirmary Burial Ground (1753-1845 AD were examined for mycolic acids that are species-specific for Mycobacterium tuberculosis. The 24% of ribs positive for mycolic acids correlated with the documented 27% tuberculosis prevalence. Mycolic acid biomarkers have the potential to provide an accurate trace of the palaeo-epidemiology of tuberculosis in ancient populations, thereby providing an indication of the overall level of poverty - a useful adjunct for archaeology.

    Prakash, Jatin

    2014-01-01

    Introduction Osteo-articular tuberculosis accounts for 1–3% of which 5–8% involves sacro-illiac joint. Isolated sacroiliac involvement is very rare. It usually presents as vague back pain. Plain radiographs are often inconclusive. Due to rarity of lesion, vague symptoms and non-conclusive X-rays the diagnosis is further delayed. We present a series of 35 patients presented with sacroiliac tuberculosis. Methods 35 patients were diagnosed of sacroiliac tuberculosis from January 2008 to December 2011. After a thorough history and clinical examination, patients were taken up for X-rays and MRI scans. Ultrasound guided needle aspiration was done from suspected area. After histological confirmation of the diagnosis, patients were treated with anti tubercular therapy. Results Persistent low back pain and difficulty with walking were noted in all patients. There were 21 males (60%) and 14 females and the age ranged from 22 to 55 years (mean: 27 years). Most of the patients (91.4%) had unilateral disease (32 patients). Results of conservative management were good. 21 (60%) of our patients achieved bony ankylosis at the end of study. 9 patients did not respond to conservative management where surgical debridement was done. 4 of these cases had MDR tuberculosis. Conclusion Sacroiliac tuberculosis must be kept as a differential in all refractory low back pain particularly in endemic areas. MRI is very helpful in early diagnosis of disease. In the early stages of the infection aspiration using a closed needle biopsy is recommended. An open biopsy is essential when the aspirate yields no growth. Open debridement should be done in those not responding to conservative management. PMID:25983488

    Pakistan ranks eighth on the list of 22 high-burden tuberculosis (TB) countries in the world according to the World Health Organisation's (WHO) Global Tuberculosis Control 2009. Including other reasons the main cause is improper and late diagnosis of the disease. PCR may play an important role to control the disease with its rapid, sensitive and specific diagnosis. But in Pakistan due to lake of knowledge about this latest technique we are not using this technique appropriately. Clinicians still trust on conventional methods of TB diagnosis, which are time consuming or insensitive. The present study was arranged to highlight the importance of PCR in TB diagnosis in pulmonary and extra-pulmonary cases and its comparison with conventional methods. Methods: Samples obtained from 290 patients of suspected TB (pulmonary or extra-pulmonary) were subjected to ZN smear examination, LJ medium culture and PCR test by amplifying 541 bp fragment of Mycobacterium tuberculosis complex genome. The present prospective study is performed at Shalamar Hospital Lahore from November 2008 to November 2010. Results: A distinctly difference was observed in the test results done by PCR and other conventional techniques in pulmonary or extra-pulmonary tuberculosis samples (p<0.001). The sensitivity of different tests was 68.62% for PCR, 26.90% for LJ medium culture, and 14.14% for ZN smear examination (p<0.05). However, there was no significant difference between different tests as for as specificity was concerned. PCR test sensitivity in pulmonary and extra-pulmonary clinical samples was 78.34 and 61.76% respectively, being significantly higher (p<0.05) when compared with sensitivity of other tests. The mean detection time for M. tuberculosis was 25 days by LJ medium culture and less than 1 day by smear examination and PCR test. Conclusion: PCR test is more sensitive than ZN smear examination and LJ medium culture for the diagnosis of TB in pulmonary and extra-pulmonary clinical samples

    Full Text Available Objective:Extensively drug-resistant tuberculosis (XDR-TB strains were emerged when multidrug-resistant TB (MDR- TB was inadequately treated. Inadequate treatment of MDR-TB cases may result in additional resistance especially non-XDR-TB and then XDR-TB. The aim of this study was to know the prevalence, resistance patterns and trends of the XDR-TB strains among the MDR-TB at a tertiary care hospital in Lucknow, India Methods: A total of 430 Mycobacterium isolates were underwent NAP test and TB MPT64 Ag test for the identification of Mycobacterium tuberculosis complex (MTBC. Drug-susceptibility test (DST was performed over MTBC for the first line drugs by 1% proportion method (Bactec and for the second-line drugs by 1% proportion method (Lowenstein- Jensen media. The XDR-TB status was further confirmed by line probe assay (GenoType® MTBDRsl assay. Results: Among the 430 isolates of mycobacterium, 365 (84.9% were MTBC and 139 (38.1% were MDR-TB respectively. Further 97 MDR-TB from “highly suspected drug resistant-TB (DR-TB” cases among MDR-TB were tested with second line drugs in which 15 (15.5% XDR-TB and 82 (84.5% were non-XDR-TB. Regarding XDR-TB status, using the 1% proportion method a 100% agreement was seen with the GenoType® MTBDRsl assay. Resistance patterns of XDR-TB were as; 10/15 (66.7% as isoniazid + rifampicin + ciprofloxacin + amikacin resistance and 5/15 (33.3% as isoniazid + rifampicin + ciprofloxacin + amikacin + kanamycin resistance. Conclusion:The prevalence of XDR-TB was 15.5% among MDR-TB. Hence laboratory testing of “highly suspected drug resistant-TB” isolates should be done for both first and second line drugs simultaneously especially in developing countries.J Microbiol Infect Dis 2013;3(4: 169-175

    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.

    To consider the relationship of the parasitic infections including cryptosporidium with chronic diarrhea. Also the effect of chronic disease as pulmonary tuberculosis (TB) and nosocomial infection on the occurrence rate of parasites in cases of chronic diarrhea. Stool samples were collected from 205 patients in teaching, general, child and maternity hospitals in Basrah, Iraq, suffering from chronic diarrhea during 2000. Out of these patients, there were 40 patients with pulmonary TB and 50 inpatients with nosocomial infection. Also 175 apparently healthy individuals who have no episodes of diarrhea for at least 2-months were served as a control group. Direct smear method and then formalin ether sedimentation method were carried out for stool samples to detect intestinal parasites. Fecal smears were prepared from the sediment and stained by the modified Ziehl Neelsen stain for the recovery of red pink oocysts of cryptosporidium. Out of the 205 examined patients, cryptosporidium oocysts were found to be excreted in 20 (9.7%) patients in comparing to 1.1% of the control group. The difference is statistically significant. There were 109 (53.2%) patients found to be positive for intestinal parasitic infections compared to 26 (14.8%) of the control group. The difference is also statistically significant. Out of the 40 TB patients, 2 (5%) were found to excrete cryptosporidium oocysts and also 27 (67.3%) were positive for intestinal parasites. In addition, there were 4 (8%) excreting cryptosporidium oocysts and 23 (46%) infecting by intestinal parasites among the in patients with nosocomial infection. Both acid and non-acid fast parasites should be considered in the differential diagnosis of undiagnosed chronic diarrhea especially among patients with pulmonary TB or nosocomial infection.

    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, 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.)

    Intestinal lymphangiectasia is defined as a dilatation of small bowel lymphatic capillaries and a loss of lymph into the bowel lumen. Clinically it is characterized by hypoproteinaemia and oedema. We present here a case of protein-losing enteropathy due to intestinal lymphangiectasia after liver transplantation in a 57-year-old man who was transplanted for hepatitis C virus. Four years after liver transplantation, the patient developed hypoalbuminaemia and ascites associated with recurrence of cirrhosis. The sudden fall in serum albumin led us to look for a cause of reduction other than or in addition to cirrhosis. Duodenal biopsies showed tall villi with dilated lymphatic vessels and widening of the villi caused by oedema, demonstrating intestinal lymphangiectasia. In this case a low-fat diet supplemented with medium-chain triacylglycerols achieved an early clinical improvement with increased serum albumin levels and ascites disappearance. Intestinal lymphangiectasia should be suspected in liver-transplanted patients developing hypoproteinaemia and hypoalbuminaemia after the recurrence of cirrhosis.

    Tuberculosis (TB) is a disease which can affect various organs, including human's genital organs such as the endometrium. Tuberculosis endometritis can cause clinical symptoms of secondary amenorrhea and infertility. Infertility in genital TB caused by the involvement of the endometrium. The case presentation is 33-year-old woman from dr. Saiful Anwar Public Hospital to consult that she has not menstruated since 5 years ago (28 years old). The diagnosis was done by performing a clinical examination until the diagnosis of secondary amenorrhea due to tuberculosis endometritis is obtained. A treatment by using category I of anti-tuberculosis drugs was done for 6 months, afterward an Anatomical Pathology observation found no signs of the tuberculosis symptoms. Based on that, patient, who was diagnosed to have secondary amenorrhea due to tuberculosis endometritis, has no signs of tuberculosis process after being treated by using category I of anti-tuberculosis drugs for 6 months.

    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 Gene Xpert MTB/ RIF assay (Xpert) is used for rapid, simultaneous detection of Mycobacterium tuberculosis (MTB) and rifampicin resistance. This study examined the accuracy of Xpert in children with suspected pulmonary tuberculosis (PTB). Children admitted to Port Moresby General Hospital with suspected PTB were prospectively enrolled between September 2014 and March 2015. They were classified into probable, possible and TB-unlikely groups. Sputum or gastric aspirates were tested by Xpert and smear microscopy; mycobacterial culture was undertaken on a subset. Children were diagnosed with TB on the basis of standard criteria which were used as the primary reference standard. Xpert, smear for acid-fast bacilli (AFB) and the Edwards TB score were compared with the primary reference standard. A total of 93 children ≤14 years with suspected PTB were enrolled; 67 (72%) were classified as probable, 21 (22%) possible and 5 (5.4%) TB-unlikely. Eighty were treated for TB based on the primary reference standard. Xpert was positive in 26/93 (28%) MTB cases overall, including 22/67 (33%) with probable TB and 4/21 (19%) with possible TB. Three (13%) samples identified rifampicin resistance. Xpert confirmed more cases of TB than AFB smear (26 vs 13, p = 0.019). The sensitivity of Xpert, AFB smear and an Edwards TB score of ≥7 was 31% (25/80), 16% (13/80) and 90% (72/80), respectively, and the specificity was 92% (12/13), 100% (13/13) and 31% (4/13), respectively, when compared with the primary reference standard. Xpert sensitivity is sub-optimal and cannot be relied upon for diagnosing TB, although a positive result is confirmatory. A detailed history and examination, standardised clinical criteria, radiographs and available tests remain the most appropriate way of diagnosing TB in children in resource-limited countries. Xpert helps confirm PTB better than AFB smear, and identifies rifampicin resistance. Practical guidelines should be used to identify children who

    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.

    Although tuberculosis is transmitted by the airborne route, direct information on the natural output of bacilli into air by source cases is very limited. We sought to address this through sampling of expelled aerosols in face masks that were subsequently analyzed for mycobacterial contamination. In series 1, 17 smear microscopy positive patients wore standard surgical face masks once or twice for periods between 10 minutes and 5 hours; mycobacterial contamination was detected using a bacteriophage assay. In series 2, 19 patients with suspected tuberculosis were studied in Leicester UK and 10 patients with at least one positive smear were studied in The Gambia. These subjects wore one FFP30 mask modified to contain a gelatin filter for one hour; this was subsequently analyzed by the Xpert MTB/RIF system. In series 1, the bacteriophage assay detected live mycobacteria in 11/17 patients with wearing times between 10 and 120 minutes. Variation was seen in mask positivity and the level of contamination detected in multiple samples from the same patient. Two patients had non-tuberculous mycobacterial infections. In series 2, 13/20 patients with pulmonary tuberculosis produced positive masks and 0/9 patients with extrapulmonary or non-tuberculous diagnoses were mask positive. Overall, 65% of patients with confirmed pulmonary mycobacterial infection gave positive masks and this included 3/6 patients who received diagnostic bronchoalveolar lavages. Mask sampling provides a simple means of assessing mycobacterial output in non-sputum expectorant. The approach shows potential for application to the study of airborne transmission and to diagnosis.

  19. Pulmonary tuberculosis

    Juhl, J.H.

    1987-01-01

    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

    Full Text Available BACKGROUND: Leucocyte activating chemokines such as CCL2, CCL3, and CXCL8 together with proinflammatory IFNgamma, TNFalpha and downmodulatory IL10 play a central role in the restriction of M. tuberculosis infections, but is unclear whether these markers are indicative of tuberculosis disease severity. METHODOLOGY: We investigated live M. tuberculosis- and M. bovis BCG-induced peripheral blood mononuclear cell responses in patients with tuberculosis (TB and healthy endemic controls (ECs, n = 36. TB patients comprised pulmonary (PTB, n = 34 and extrapulmonary groups, subdivided into those with less severe localized extrapulmonary TB (L-ETB, n = 16 or severe disseminated ETB (D-ETB, n = 16. Secretion of CCL2, IFNgamma, IL10 and CCL3, and mRNA expression of CCL2, TNFalpha, CCL3 and CXCL8 were determined. RESULTS: M. tuberculosis- and BCG-induced CCL2 secretion was significantly increased in both PTB and D-ETB (p<0.05, p<0.01 as compared with L-ETB patients. CCL2 secretion in response to M. tuberculosis was significantly greater than to BCG in the PTB and D-ETB groups. M. tuberculosis-induced CCL2 mRNA transcription was greater in PTB than L-ETB (p = 0.023, while CCL2 was reduced in L-ETB as compared with D-ETB (p = 0.005 patients. M. tuberculosis-induced IFNgamma was greater in L-ETB than PTB (p = 0.04, while BCG-induced IFNgamma was greater in L-ETB as compared with D-ETB patients (p = 0.036. TNFalpha mRNA expression was raised in PTB as compared with L-ETB group in response to M. tuberculosis (p = 0.02 and BCG (p = 0.03. Mycobacterium-induced CCL3 and CXCL8 was comparable between TB groups. CONCLUSIONS: The increased CCL2 and TNFalpha in PTB patients may support effective leucocyte recruitment and M. tuberculosis localization. CCL2 alone is associated with severity of TB, possibly due to increased systemic inflammation found in severe disseminated TB or due to increased monocyte infiltration to lung parenchyma in pulmonary disease.

    We present a healthy male subject who developed progressive visual loss in the left eye initially diagnosed as optic neuritis. Upon suspicion of infectious etiology, testing was positive for tuberculosis. There were no signs or symptoms of active systemic tuberculosis infection. The patient responded swiftly to antimycobacterial therapy with return of vision and resolution of disc swelling. Positive purified protein derivative skin test, negative chest radiograph, negative systemic workup, negative workup for other causes of unilateral optic neuritis and quick response to mycobacterial therapy reaffirm the entity of isolated optic disc tuberculosis similar to isolated choroidal tuberculosis without systemic manifestation.

    Based on analysis of data collected from the national tuberculosis prevention program in Djibouti between 1990 and 1996, the authors analyzed the relationship between HIV infection and tuberculosis. The study cohort comprised a total of 22,000 patients including 14,000 with documented HIV infection. Although HIV infection probably worsened the situation, it was neither the only nor the main factor involved in the resurgence of tuberculosis. Demographic growth, higher population density, and increasing poverty as well as the quality of the national tuberculosis prevention program must be taken into account. The incidence of smear-negative tuberculosis was not significantly higher in HIV-infected patients (incidence of smear positive cases, > 92%). Extrapulmonary tuberculosis especially of pleural involvement was more common (15% versus 9.4%). Treatment was effective in HIV-infected patients. If directly observed (DOT) therapy was used, there was no risk of emergence of multidrug-resistant tuberculosis strains. Drug side-effects associated with the protocols used in Djibouti were not greater in HIV-infected patients. Most additional mortality observed in HIV-infected tuberculosis patients (10.5% versus 2%) was due to progression of HIV infection.

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. 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. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

    Recent development of tuberculosis in Japan tends to converge on a specific high risk group. The proportion of tuberculosis developing particularly from the compromised hosts in the high risk group is especially high. At this symposium, therefore, we took up diabetes mellitus, gastrectomy, dialysis, AIDS and the elderly for discussion. Many new findings and useful reports for practical medical treatment are submitted; why these compromised hosts are predisposed to tuberculosis, tuberculosis diagnostic and remedial notes of those compromised hosts etc. It is an important question for the future to study how to prevent tuberculosis from these compromised hosts. 1. Tuberculosis in diabetes mellitus: aggravation and its immunological mechanism: Kazuyoshi KAWAKAMI (Department of Internal Medicine, Division of Infectious Diseases, Graduate School and Faculty of Medicine, University of the Ryukyus). It has been well documented that diabetes mellitus (DM) is a major aggravating factor in tuberculosis. The onset of this disease is more frequent in DM patients than in individuals with any underlying diseases. However, the precise mechanism of this finding remains to be fully understood. Earlier studies reported that the migration, phagocytosis and bactericidal activity of neutrophils are all impaired in DM patients, which is related to their reduced host defense to infection with extracellular bacteria, such as S. aureus and E. colli. Host defense to mycobacterial infection is largely mediated by cellular immunity, and Th1-related cytokines, such as IFN-gamma and IL-12, play a central role in this response. It is reported that serum level of these cytokines and their production by peripheral blood mononuclear cells (PBMC) are reduced in tuberculosis patients with DM, and this is supposed to be involved in the high incidence of tuberculosis in DM. Our study observed similar findings and furthermore indicated that IFN-gamma and IL-12 production by BCG-stimulated PBMC was lower

    To characterize tuberculosis drug-resistance using anti-tuberculosis drug-sensitivity tests in Colombian prisoners. Descriptive-retrospective analyses were performed on cases of tuberculosis in prisoners. Samples were evaluated by the National Reference Laboratory. Conditions like gender, TB/VIH co-infection and drug-resistance were evaluated. Anti-tuberculosis drug-sensitivity tests were carried out on 72 prisoners. Results showed a distribution of 90.7 % of cases in males and 9.3 % of cases in females. 12 % of cases were TB/VIH co-infections, 94 % of the cases had not received any anti-tuberculosis treatment before, six isolates were drug-resistant corresponding to 8.8 % of total cases, and two cases were multi drug-resistant representing 1.3 % of the cases. Of the drug-resistant cases, 83.3 % were TB/VIH co-infected. Previously treated cases corresponded to 5.6 % of the total cases analyzed. One case with TB/VIH co-infection and rifampicin resistance was observed, representing 1.3 % of the total cases. The government must create a clear policy for prisoners in Colombia, because a high rate of disease in prisoners was observed. In addition, the results showed an association between drug-resistance and TB/VIH co-infection. Overcrowding and low quality of life in penitentiaries could become an important public health problem.

    Full Text Available Tuberculosis and intestinal parasites affect primarily low social and economic level populations, living clustered in precarious habitational settings. One of the interesting aspects of this interaction is the parasitism influence in cellular response to tuberculosis. In the present study, we evaluated the prevalence of enteroparasitosis in tuberculosis patients, HIV-infected and non HIV infected, and we observed the influence of helminth presence in the response to tuberculin skin test (TST and tuberculosis clinical outcomes. From 607 clinical records reviewed, 327 individuals met the study inclusion criteria and did not present any exclusion criteria. The prevalence of enteroparasites observed was 19.6%. There was no significant association among TST result and the variables related to the presence of: helminthes, protozoa, and stool test for parasites result (p>0.5. Considering the survival of this cohort, we may observe that there is no significant difference (p>0.05 between the survival curves of parasited and non parasited individuals. Solely the variable "eosinophils" presents a statistically significant association (p<0.001 with helminthes, all other associations are considered not significant. Our findings neither show an association between helminthic infection and a favorable tuberculosis outcome, nor between parasitism and TST response, unlike other in vitro studies. Apparently, experimental data do not correspond to the clinical findings.

    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

    Full Text Available Faiz I Shakarchi1,21Ibn Al-Haetham Teaching Eye Hospital, 2Department of Opthalmology, Medical College, Al-Mustansiriya University, Baghdad, IraqAbstract: The World Health Organization currently estimates that nearly two billion people, or one-third of the world’s population, are infected by tuberculosis, and that roughly 10% of the infected people are symptomatic. Tuberculosis affects the lungs in 80% of patients, while in the remaining 20% the disease may affect other organs, including the eye. Uveitis can be seen concurrently with tuberculosis, but a direct association is difficult to prove. Ocular tuberculosis is usually not associated with clinical evidence of pulmonary tuberculosis, as up to 60% of extrapulmonary tuberculosis patients may not have pulmonary disease. The diagnosis of tuberculous uveitis is often problematic and in nearly all reported cases, the diagnosis was only presumptive. Tuberculous uveitis is a great mimicker of various uveitis entities and it can be considered in the differential diagnosis of any type of intraocular inflammation. It is still unknown if ocular manifestations result from a direct mycobacterium infection or hypersensitivity reaction and this is reflected on the management of tuberculous uveitis. Prevalence of tuberculosis as an etiology of uveitis may reach up to 10% in endemic areas. Tuberculous uveitis is a vision-threatening disease that inevitably leads to blindness if not properly diagnosed and treated. The aim of this review is to illustrate the various clinical features and management of presumed tuberculous uveitis. The current review focuses on the diagnostic criteria, significance of tuberculin skin test, and use of systemic corticosteroids in the management of tuberculous uveitis as recommended in recent publications.Keywords: tuberculosis, uveitis, choroiditis, tuberculin skin test

    Renato Simões Gaspar

    Full Text Available ABSTRACT Objective: To investigate the reported cases of tuberculosis and of tuberculosis-HIV co-infection in Brazil between 2002 and 2012. Methods: This was an observational study based on secondary time series data collected from the Brazilian Case Registry Database for the 2002-2012 period. The incidence of tuberculosis was stratified by gender, age group, geographical region, and outcome, as was that of tuberculosis-HIV co-infection. Results: Nationally, the incidence of tuberculosis declined by 18%, whereas that of tuberculosis-HIV co-infection increased by 3.8%. There was an overall decrease in the incidence of tuberculosis, despite a significant increase in that of tuberculosis-HIV co-infection in women. The incidence of tuberculosis decreased only in the 0- to 9-year age bracket, remaining stable or increasing in the other age groups. The incidence of tuberculosis-HIV co-infection increased by 209% in the ≥ 60-year age bracket. The incidence of tuberculosis decreased in all geographical regions except the south, whereas that of tuberculosis-HIV co-infection increased by over 150% in the north and northeast. Regarding the outcomes, patients with tuberculosis-HIV co-infection, in comparison with patients infected with tuberculosis only, had a 48% lower chance of cure, a 50% greater risk of treatment nonadherence, and a 94% greater risk of death from tuberculosis. Conclusions: Our study shows that tuberculosis continues to be a relevant public health issue in Brazil, because the goals for the control and cure of the disease have yet to be achieved. In addition, the sharp increase in the incidence of tuberculosis-HIV co-infection in women, in the elderly, and in the northern/northeastern region reveals that the population of HIV-infected individuals is rapidly becoming more female, older, and more impoverished.

  6. Mycobacterium tuberculosis TlyA Protein Negatively Regulates T Helper (Th) 1 and Th17 Differentiation and Promotes Tuberculosis Pathogenesis*

    Mycobacterium tuberculosis, the causative agent of tuberculosis, is an ancient pathogen and a major cause of death worldwide. Although various virulence factors of M. tuberculosis have been identified, its pathogenesis remains incompletely understood. TlyA is a virulence factor in several bacterial infections and is evolutionarily conserved in many Gram-positive bacteria, but its function in M. tuberculosis pathogenesis has not been elucidated. Here, we report that TlyA significantly contributes to the pathogenesis of M. tuberculosis. We show that a TlyA mutant M. tuberculosis strain induces increased IL-12 and reduced IL-1β and IL-10 cytokine responses, which sharply contrasts with the immune responses induced by wild type M. tuberculosis. Furthermore, compared with wild type M. tuberculosis, TlyA-deficient M. tuberculosis bacteria are more susceptible to autophagy in macrophages. Consequently, animals infected with the TlyA mutant M. tuberculosis organisms exhibited increased host-protective immune responses, reduced bacillary load, and increased survival compared with animals infected with wild type M. tuberculosis. Thus, M. tuberculosis employs TlyA as a host evasion factor, thereby contributing to its virulence. PMID:25847237

  7. 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

    Full Text Available Bovine tuberculosis is caused by the infection of Mycobacterium tuberculosis var. bovis (M. bovis. This species is one of Mycobacterium tuberculosis complex, can infect wide range of hosts: cattle and other domesticated animals, wild mammals and humans (zoonotic. M. bovis bacterium from infected hosts can be transmitted to other susceptible animals and humans through respiratory excretes and secretion materials. Humans can be infected with M. bovis by ingested M. bovis contaminated animal products, unpasteurised milk from tuberculosis cows or through respiratory route of contaminated aerosol. Bovine tuberculosis at the first stage does not show any clinical sign but as the disease progress in the next stage which may take several months or years, clinical signs may arise, suh as: fluctuative body temperature, anorexia, lost body weight, coughing, oedema of lymph nodes, increased respiratory frequencies. Pathological lesion of bovine tuberculosis is characterised by the formation of granulomas (tubercles, in which bacterial cells have been localised, most in lymph nodes and pulmonum, but can occur in other organs. The granulomas usually arise in small nodules or tubercles appear yellowish either caseus, caseo-calcareus or calcified. In Indonesia, bovine tuberculosis occurred in dairy cattle since 1905 through the imported dairy cows from Holland and Australian. It was unfortunate that until recently, there were not many research and surveilances of bovine tuberculosis conducted in this country, so the distribution of bovine tuberculosis is unknown. Early serological diagnosis can be done on live cattle by means of tuberculin tests under field conditions. Confirmation can be done by isolation and identification of excreted and secreted samples from the slaughter house. Antibiotic treatment and vaccination were uneffective, therefore the effective control of bovine tuberculosis is suggested by tuberculin tests and by slaughtering the selected

    The mortality rate still is an important index for assessment of tuberculosis. Statistical records are kept on the mortality rate on a worldwide basis--more than in the case of other tuberculosis parameters. They allow us to make valuable comparisons. They are also useful because the mortality is closely related to the morbidity. The present thesis is based on comparative figures from the 1989 volume of the WHO Health Statistics Annual. Various countries have been specially selected by the publisher--and subsequently also by us--for sake of clarity. The figures vary strongly within these countries, which was to be expected. The mortality rate varies in Europe (for each 100,000 residents) e.g. from 0.2 in the Netherlands to 8.15 in the Soviet Union. In the Americas the rates vary from 0.4 for Canada to 12.9 for Ecuador. In the Western Pacific region the mortality rates vary from 0.35 for Australia to 14.65 for China. On a worldwide basis, the share of deaths from tuberculosis among all causes of death varies from 0.02% in the Netherlands to 2.10% in the Republic of Korea. The relation of tuberculosis deaths with regard to sexes in Switzerland: 75.7% men, 24.3% women, which is more or less the European average. The lower the mortality rate for tuberculosis are, the lower the difference between the sexes appears to be. Similar facts are found with regard to the distribution of tuberculosis deaths according to age groups: the lower the tuberculosis rate, the more tuberculosis is found in older age groups. The tuberculosis deaths are percentage-wise similarly distributed to the respiratory organs and the other tuberculosis forms.(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Quality of tuberculosis care by Indian pharmacies: Mystery clients offer new insights

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available For many patients in India, pharmacies are their first point of contact, where most drugs, including antibiotics, can be purchased over-the-counter (OTC. Recent standardised (simulated patient studies, covering four Indian cities, provide new insights on how Indian pharmacies manage patients with suspected or known tuberculosis. Correct management of the simulated patients ranged from 13% to 62%, increasing with the certainty of the TB diagnosis. Antibiotics were frequently dispensed OTC to patients, with 16% to 37% receiving such drugs across the cases. On a positive note, these studies showed that no pharmacy dispensed first-line anti-TB drugs. Engagement of pharmacies is important to not only improve TB detection and care, but also limit the abuse of antibiotics.

  11. Mycobacterium tuberculosis Metabolism

    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.

    1998-01-01

    To evaluate the ultrasonographic and CT findings of hepatosplenic tuberculosis Materials and Methods: We retrospectively reviewed the ultrasonographic and CT findings of confirmed hepatosplenic tuberculosis in 12 patients. Six were men and six were women ; their average age was 41, and most were in their twenties. Lesions of the liver and spleen, as well as associated findings such as abdominal tuberculosis and other organ involvement of tuberculosis were analyzed. Results : There were three cases of hepatic tuberculosis, seven of splenic tuberculosis, and two of hepatosplenic involvement of tuberculosis. On the basis of the ultrasonographic and CT findings, hepatosplenic tuberculosis was classified as one of two patterns : miliary or micronodular, ormacronodular. The micronodular type was more common (9/12 cases) being characterized by innumerable micronodules,and with easy coalescence in the liver and spleen in five of the nine cases. The macronodular type of low density mass was noted in the other three patients. Splenomegaly was noted in 12 cases and hepatomegaly in ten. Pulmonary tuberculosis-including the miliary type(n=5)-was noted in eight patients. Associated abdominal tuberculosis such as lymphadenopathy with central low density and peripheral rim enhancement (n=6), tuberculous peritonitis(n=3),highly attenuated ascites(n=6), adrenal tuberculosis(n=1), renal tuberculosis(n=1), ovarian abscess(n=1), psoasabscess(n=1), and systemic tuberculosis such as central nervous system tuberculoma(n=2), cervical lymphadenopathy(n=4) and tuberculous spondylitis(n=1) were noted. Conclusion : Ultrasonography and CT were valuable in the detection and diagnosis of hepatosplenic tuberculosis

    Directory of Open Access Journals (Sweden)

    Gabriela Capriogli Oliveira

    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.

    Jagodziński, Jacek; Zielonka, Tadeusz M

    2010-01-01

    Migration of population contributes to the transmission of tuberculosis (TB), particularly multidrug-resistant tuberculosis. In the countries of Western Europe, the immigrants' inflow contributes to the deterioration of the epidemiological situation. Majority of newly detected TB cases in some countries were affirmed among immigrant and foreign born population. In Poland, this problem has not been investigated up to 2005. The aim of the study was the assessment of the occurrence of tuberculosis in foreigners treated in the Mazovian Centre for Treatment of Lung Diseases and Tuberculosis in Otwock. This work had a retrospective character. The number of cases of tuberculosis in foreigners admitted between 2002 and 2007 was calculated from the data base of the Mazovian Centre for Treatment of Lung Diseases and Tuberculosis; 125 patients, whose basic demographic data, bacteriological status and the radiological changes suggested TB, were included in the study. The foreigners made up to 0.5-1.7% all tuberculosis cases treated in Mazovian Centre for Treatment of Lung Diseases and Tuberculosis. Among confirmed cases, twenty four nationalities were seen. Nationals of the Russian Federation (coming from the Republic of Chechnya) formed the biggest group (24%), followed by the Vietnamese (21%) and the Ukrainians (12%). Most of all cases were young men (77%; average age - 34 years). Children made up to 12% of all cases. Tuberculosis of lungs was predominating, and there were culture confirmed extrapulmonary locations in 13.6% of cases. Bacteriological confirmation was achieved in 53% of cases, but up to 22.7% cases were resistant to one of the antituberculosis medicines and 13.6% was multidrug-resistant. Despite the fact, that foreigners made up a small proportion among all the patient treated for tuberculosis in Mazovia, their number systematically increases. High proportion of multidrug-resistant tuberculosis reported in foreign-born cases is a concern.

This study compared the results of polymerase chain reaction (PCR amplification of M . tuberculosis specific DNA sequences (IS6110, 65kDa, 38kDa and mRNA coding for 85 B protein from different clinical samples of pulmonary and extrapulmonary tuberculosis. Methods: One hundred and seventy-two clinical samples from suspected tuberculosis patients were tested for smear examination, culture (LJ and rapid BACTEC 460 TB system and PCR. PCR was performed with specific primers for the targets: IS6110, 65kDa, 38kDa and 85B. Results: Each PCR test was found to have a much higher positivity than conventional test and BACTEC culture ( P < 0.05. Smear positive samples (56 and the samples (36 showing positive results by conventional methods (smear and LJ medium culture and BACTEC were found to be positive by all PCR protocols. No significant difference was found between the four PCR protocols ( P >0.05. The primer specific for amplifying the 123bp IS6110 fragment gave the highest positivity (83%, followed by 65kDa, 38kDa and 85B RT-PCR in descending order. Conclusions: These data suggest that the presence of IS6110 correlates more closely with the diagnosis of clinical tuberculosis than that of 65kDa, 38kDa and 85B proteins.

    2003-01-01

    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

  10. Pulmonary Immune-Compartment-Specific Interferon Gamma Responses in HIV-Infected Individuals with Active Tuberculosis (TB in an Area of High TB Prevalence

    Directory of Open Access Journals (Sweden)

    S. Buldeo

    2012-01-01

    Full Text Available There is a paucity of data on the pulmonary immune-compartment interferon gamma (IFNγ response to M. tuberculosis, particularly in settings of high tuberculosis (TB prevalence and in HIV-coinfected individuals. This data is necessary to understand the diagnostic potential of commercially available interferon gamma release assays (IGRAs in both the pulmonary immune-compartment and peripheral blood. We used intracellular cytokine staining by flow cytometry to assess the IFNγ response to purified protein derivative (PPD and early secretory antigen 6 (ESAT6 in induced sputa (ISp and blood samples from HIV-infected, smear-negative, TB suspects. We found that individuals with active TB disease produced significantly less IFNγ in response to PPD in their induced sputa samples than individuals with non-active TB (control group. This difference was not reflected in the peripheral blood, even within the CD27− CD4+ memory T lymphocyte population. These findings suggest that progression to active TB disease may be associated with the loss of IFNγ secretion at the site of primary infection. Our findings highlight the importance of studying pulmonary immune-compartment M. tuberculosis specific responses to elucidate IFNγ secretion across the spectrum of TB disease.

    The outcome of the chemotherapy for pulmonary, extraplumonary and disseminated tuberculosis is not well documented, especially in developing countries. This study assessed tuberculosis treatment outcome, cure-to-treatment ratio and mortality among all types of tuberculosis patients in a tertiary care setting in Saudi Arabia. All cases diagnosed and treated for active Mycobacterium tuberculosis infection between 1991 and 2000 were included retrospectively. Data collected included type of tuberculosis involvement, treatment outcome, relapse and co-morbidities. Over a ten-year period, 535 case of tuberculosis were diagnosed and treated. Isolated pulmonary tuberculosis was identified in 141 cases (26.4%), extrapulmonary tuberculosis in 339 cases (63.3%). Co-morbidities were noted in 277 (52%) patients. Immunosuppression was found in 181 (34%) cases. The cure rate was 82%. The cure-to-treatment ratio was 86% in extrapulmonary tuberculosis and 65% in disseminated tuberculosis. Overall mortality was 18%. Disseminated tuberculosis had the highest mortality (34.9%), followed by pulmonary (21.8%), the extrapulmonary tuberculosis (13.6%). Forty-seven percent of all mortalities were directly related to tuberculosis. Relapse was documented in 14 out of 349 patients (4%) who had 24 months of follow-up. Despite tertiary care support, complicated tuberculosis carries a high mortality. Earlier diagnosis and complete appropriate chemotherapy are essential for improved outcome. (author)

    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.

    Shifting X-ray interpretation to non-radiologists can help to address radiologist shortages in developing countries. To determine the change in accuracy of non-radiologists and radiologists for the radiographic diagnosis of paediatric tuberculosis after a short skill-development course. 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.)

    Tuberculosis remains a global health problem with an enormous burden of disease, estimated at 10.4 million new cases in 2015. To stop the tuberculosis epidemic, it is critical that we interrupt tuberculosis transmission. Further, the interventions required to interrupt tuberculosis transmission must be targeted to high-risk groups and settings. A simple cascade for tuberculosis transmission has been proposed in which (1) a source case of tuberculosis (2) generates infectious particles (3) that survive in the air and (4) are inhaled by a susceptible individual (5) who may become infected and (6) then has the potential to develop tuberculosis. Interventions that target these events will interrupt tuberculosis transmission and accelerate the decline in tuberculosis incidence and mortality. The purpose of this article is to provide a high-level overview of what is known about tuberculosis transmission, using the tuberculosis transmission cascade as a framework, and to set the scene for the articles in this series, which address specific aspects of tuberculosis transmission. © The Author 2017.

    Background The prognosis, specifically the case fatality and duration, of untreated tuberculosis is important as many patients are not correctly diagnosed and therefore receive inadequate or no treatment. Furthermore, duration and case fatality of tuberculosis are key parameters in interpreting epidemiological data. Methodology and Principal Findings To estimate the duration and case fatality of untreated pulmonary tuberculosis in HIV negative patients we reviewed studies from the pre-chemotherapy era. Untreated smear-positive tuberculosis among HIV negative individuals has a 10-year case fatality variously reported between 53% and 86%, with a weighted mean of 70%. Ten-year case fatality of culture-positive smear-negative tuberculosis was nowhere reported directly but can be indirectly estimated to be approximately 20%. The duration of tuberculosis from onset to cure or death is approximately 3 years and appears to be similar for smear-positive and smear-negative tuberculosis. Conclusions Current models of untreated tuberculosis that assume a total duration of 2 years until self-cure or death underestimate the duration of disease by about one year, but their case fatality estimates of 70% for smear-positive and 20% for culture-positive smear-negative tuberculosis appear to be satisfactory.

    Pulmonary tuberculosis (TB) is a common worldwide lung infection. The radiological features show considerable variation, but in most cases they are characteristic enough to suggest the diagnosis. Classically, tuberculosis is divided into primary, common in childhood, and postprimary, usually presenting in adults. The most characteristic radiological feature in primary tuberculosis is lymphadenopathy. On enhanced CT, hilar and mediastinal nodes with a central hypodense area suggest the diagnosis. Cavitation is the hallmark of postprimary tuberculosis and appears in around half of patients. Patchy, poorly defined consolidation in the apical and posterior segments of the upper lobes, and in the superior segment of the lower lobe is also commonly observed. Several complications are associated with tuberculous infection, such as hematogenous dissemination (miliary tuberculosis) or extension to the pleura, resulting in pleural effusion. Late complications of tuberculosis comprise a heterogeneous group of processes including tuberculoma, bronchial stenosis bronchiectasis, broncholithiasis, aspergilloma, bronchoesophageal fistula and fibrosing mediastinitis. Radiology provides essential information for the management and follow up of these patients and is extremely valuable for monitoring complications.

    To evaluate the value of T-SPOT.TB assay in the diagnosis of pulmonary tuberculosis within different age groups. We analyzed 1 518 suspected pulmonary tuberculosis (PTB) patients who were admitted to the Beijing Chest Hospital from November 2012 to February 2014 and had valid T-SPOT.TB tests before anti-tuberculosis therapy. The 599 microbiologically and/or histopathologically-confirmed PTB patients (16-89 years old, 388 males and 211 females) and 235 non-TB patients (14-85 years old, 144 males and 91 females) were enrolled for the analysis of diagnostic performance of T-SPOT.TB, while patients with uncertain diagnosis or diagnosis based on clinical impression (n=684) were excluded from the analysis. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of the T-SPOT.TB were analyzed according to the final diagnosis. Furthermore, the diagnostic performance of T-SPOT.TB assay in the younger patients (14-59 years old) and elderly patients (60-89 years old) were also analyzed respectively. Categorical variables were compared by Pearson's Chi-square test, while continuous variables were compared by the Mann-Whitney U-test. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of the T-SPOT.TB in diagnosis of PTB were 90.1% (540/599), 65.5% (154/235), 86.9% (540/621), 72.3% (154/213), 2.61, and 0.15, respectively. The sensitivity and specificity of T-SPOT.TB assay were 92.6% (375/405) and 75.6% (99/131), respectively in the younger patients, and 85.0% (165/194), 52.9% (55/104) respectively in the elderly patients. The sensitivity and specificity of T-SPOT.TB assay in the younger patients were significantly higher than those in the elderly patients (Pspot forming cells in the younger PTB patients were significantly higher than in the elderly PTB patients [300 (126, 666)/10(6) PBMCs vs. 258 (79, 621

    Background Sputum smear microscopy is the standard diagnostic method for detection of smear positive pulmonary tuberculosis (TB). Insufficient quality of sputum might result in missing cases. In this study we aimed at assessing the quality of sputum in a district in Central Java and determining patient and health worker factors associated with submission of three good quality sputum samples. Methods In 16 health centers information was collected on the quality of sputum submitted by TB suspects, i.e. volume, color, and viscosity. TB suspects were interviewed to assess their knowledge of TB, motivation to provide sputum and whether they were informed why and how to produce a sputum sample. Health workers were interviewed to assess what information they provided to TB suspects about the reason for sputum examination, methods to produce sputum and characteristics of a good quality sputum sample. All health worker and patient factors were evaluated for association with sputum quality. Results Of 387 TB suspects, 294 (76.0%) could be traced and interviewed, and of 272 (70.3%) information about sputum quality was available. Of those 203 (74.6%) submitted three samples, 90 (33.1%) provided at least one good sample, and 37 (13.6%) provided three good quality sputum samples. Of the 272 TB suspects, 168 (61.8%) mentioned that information on the reason for sputum examination was provided, 66 (24.3%) remembered that they were informed about how to produce sputum and 40 (14.7%) recalled being informed about the characteristics of good quality sputum. Paramedics reported to provide often/always information on the importance of sputum examination, and when to produce sputum. Information on how to produce sputum and characteristics of a good sputum sample was less often provided. None of the studied patient characteristics or health worker factors was associated with providing good quality sputum. Conclusion A considerable number of TB suspects did not provide three sputum samples

    Objective: To evaluate the imaging features of multidrug-resistant tuberculosis by collecting multidrug-resistant tuberculosis verified by test of drug-sensitivity, which defined as resistance to three anti-tuberculosis drugs. Methods:Fifty-one cases of multidrug-resistant tuberculosis were categorized as group of observed, and 46 cases of drug sensitive tuberculosis were categorized as control. Cultures were positive for Mycobacterium tuberculosis in all cases with no other illness such as diabetes mellitus. All patients had chest radiographs available for review, while 64 cases had tomography and 30 cases had CT during the same time. All images were analyzed by three of the radiologists, disagreement among them was discussed and a consensus was reached. Results: There was no difference in the distribution of lesions between the multidrug-resistant tuberculosis group and control group. However, the radiological findings in the multidrug-resistant tuberculosis group were significantly more common than in control group, such as multiple nodules (10 cases), disseminated foci (23 cases), cavity (9 cases), and complications (10 cases). Comparing the dynamic cases, deteriorating cases were more commonly seen in observed group than in control group, while improved cases were less in observed group than in control group. Conclusion: Multidrug-resistant tuberculosis is the most serious tuberculosis, which is characterized with significant activity, more disseminated foci, cavity, and complications. The lesion deteriorated while correct anti-tuberculosis treatment is applied. (authors)

    Early detection and appropriate treatment are the keys to tuberculosis control. In particular, providing appropriate treatment for tuberculosis in patients with HIV infection, rheumatoid arthritis (RA), chronic hepatic disease, or renal failure necessitating hemodialysis, and taking appropriate measures against adverse reactions to antituberculosis drugs are issues of critical importance. This mini-symposium, four experts explained the current status of "treatment of tuberculosis in patients with comorbidities" and proposed measures to address these problems. Dr. Aoki talked about "HIV infection complicated by tuberculosis." To the next, Dr. Yoshinaga gave a talk on "treatment of tuberculosis in RA patients receiving biological agents. Further, Dr. Sasaki lectured on "tuberculosis in patients with hepatic disease/impairment". Lastly, Dr. Takamori gave a lecture on "tuberculosis in patients with renal disease and those on hemodialysis. Tuberculosis patients often have some underlying diseases, and adverse reactions caused by antituberculosis drugs, such as hepatic and renal impairments, are matters of concern. I believe that this mini-symposium has provided useful information for physicians engaged in tuberculosis treatment and for many other healthcare professionals as well.

    The diagnosis of smear-negative pulmonary tuberculosis (PTB) is particularly challenging, and automated liquid culture and molecular line probe assays (LPA) may prove particularly useful. The objective of our study was to evaluate the diagnostic potential of automated liquid culture (ALC) technology and commercial LPA in sputum smear-negative PTB suspects. Spot sputum samples were collected from 145 chest-symptomatic smear-negative patients and subjected to ALC, direct drug susceptibility test (DST) testing and LPA, as per manufacturers' instructions. A diagnostic yield of 26.2% was observed among sputum smear-negative TB suspects with 47.4% of the culture isolates being either INH- and/or rifampicin-resistant. Complete agreement was observed between the results of ALC assay and LPA except for two isolates which demonstrated sensitivity to INH and rifampicin at direct DST but were rifampicin-resistant in LPA. Two novel mutations were also detected among the multidrug isolates by LPA. In view of the diagnostic challenges associated with the diagnosis of TB in sputum smear-negative patients, our study demonstrates the applicability of ALC and LPA in establishing diagnostic evidence of TB.

    Full Text Available Tuberculosis is a very important problem for public health all around the world. In this study, 168 patients with TB who were treated in Batman Tuberculosis Control Dispensary in 2003 were retrospectively assessed. Ninety six of our cases were male, 72 were female. Eighty one patients who underwent for the tuberculous treatment were with pulmonary tuberculosis and 87 cases were with extrapulmonary tuberculosis. Acid fast bacilli (AFB at sputum was positive in 66.17% of the cavitary pulmonary TB cases before treatment and only one patient’s sputum was positive in pulmonary tuberculosis without cavity. Results of the tuberculosis treatment of cases revealed that one case left the treatment, 3 patients were inharmonious, 3 patients were dead, 161 patients were cured. Success rate of treatment was 95,83% (5 of these cases were cured and 156 patients completed the treatment. These data suggest that in order to increase the rate of the cure, bacteriological examination of the sputum should be considered at the end of the treatment like as the beginning.

    Tuberculosis remains a major global medical challenge and concern. In the world's population of over 7.4 billion people, 8.6 million are estimated to be infected with Mycobacterium tuberculosis; another 2.2 billion have latent tuberculosis. There is an annual incidence of 16,000 new cases in the USA and 7-8 million new cases worldwide, of which 440,000 are multidrug-resistant or extensively multidrug-resistant, mainly in developing countries or emerging economies. According to the World Health Organization, the incidence of tuberculosis is 133 cases per 100,000 of the population; 3.3% new cases are drug resistant and 20% are already treated cases. Of the drug-resistant cases, 9.7% are extensively drug-resistant. The annual global mortality attributable to tuberculosis is over 1.3 million people. The association with HIV/AIDS in 430,000 people has compounded the global concern and challenge. This review presents the historical indications for surgical treatment of tuberculosis, reviews the current literature and clinical experience, and collates this into increased awareness and contemporary understanding of the indications and need for surgery in primary active tuberculosis, adjuvant surgical therapy for multidrug-resistant tuberculosis, and the complications of chronic tuberculosis sequelae or previous tuberculosis surgery. © The Author(s) 2016.

    2009-11-01

    Full Text Available Abstract Background Tuberculous spondylitis (Pott's disease is an ancient human disease. Because it is rare in high-income, tuberculosis (TB low incidence countries, misdiagnoses occur as sufficient clinical experience is lacking. Case presentation We describe a fatal case of a patient with spinal TB, who was mistakenly irradiated for suspected metastatic lung cancer of the spine in the presence of a solitary pulmonary nodule of the left upper lobe. Subsequently, the patient progressed to central nervous system TB, and finally, disseminated TB before the accurate diagnosis was established. Isolation and antimycobacterial chemotherapy were initiated after an in-hospital course of approximately three months including numerous health care related contacts and procedures. Conclusion The rapid diagnosis of spinal TB demands a high index of suspicion and expertise regarding the appropriate diagnostic procedures. Due to the devastating consequences of a missed diagnosis, Mycobacterium tuberculosis should be considered early in every case of spondylitis, intraspinal or paravertebral abscess. The presence of certain alarm signals like a prolonged history of progressive back pain, constitutional symptoms or pulmonary nodules on a chest radiograph, particularly in the upper lobes, may guide the clinical suspicion.

    Full Text Available Opportunistic infections usually occur in patients with an immunocompromised state, and can be severe. Cryptoccocal meningitis is a fatal condition if left untreated, and is usually found in such patients. We report the case of an adult patient with cryptoccocal meningitis secondary to intestinal lymphangiectasia. A 30 year old female was admitted to our hospital for meningitis. Biochemical and radiological investigations were performed. A cerebrospinal fluid latex agglutination test showed positive cryptoccocal antigen. In addition, there were features of humoral and cell mediated immunity deficiency (lymphopenia, hypoalbuminemia, hypogammaglobulinemia, with a negative human immunodeficiency virus (HIV test by enzyme linked immunosorbent assay and polymerase chain reaction. An upper gastroduodenoscopy was performed, which showed multiple lymphangiectasias, and a biopsy confirmed the diagnosis of primary intestinal lymphangiectasia (PIL. The patient was treated with intravenous amphotericin B and oral flucytosine, and the meningitis resolved. PIL should be suspected in patients with cryptoccocal meningitis, combined with humoral and cell mediated immunity with a negative HIV test. The management issues, in addition to antifungal therapy, include nutritional supplements for the protein losing enteropathy.

    Co-infections with parasites or viruses drive tuberculosis dynamics in humans, but little is known about their effects in other non-human hosts. This work aims to investigate the relationship between Mycobacterium bovis infection and other pathogens in wild boar (Sus scrofa), a recognized reservoir of bovine tuberculosis (bTB) in Mediterranean ecosystems. For this purpose, it has been assessed whether contacts with common concomitant pathogens are associated with the development of severe bTB lesions in 165 wild boar from mid-western Spain. The presence of bTB lesions affecting only one anatomic location (cervical lymph nodes), or more severe patterns affecting more than one location (mainly cervical lymph nodes and lungs), was assessed in infected animals. In addition, the existence of contacts with other pathogens such as porcine circovirus type 2 (PCV2), Aujeszky's disease virus (ADV), swine influenza virus, porcine reproductive and respiratory syndrome virus, Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, Haemophilus parasuis and Metastrongylus spp, was evaluated by means of serological, microbiological and parasitological techniques. The existence of contacts with a structured community of pathogens in wild boar infected by M. bovis was statistically investigated by null models. Association between this community of pathogens and bTB severity was examined using a Partial Least Squares regression approach. Results showed that adult wild boar infected by M. bovis had contacted with some specific, non-random pathogen combinations. Contact with PCV2, ADV and infection by Metastrongylus spp, was positively correlated to tuberculosis severity. Therefore, measures against these concomitant pathogens such as vaccination or deworming, might be useful in tuberculosis control programmes in the wild boar. However, given the unexpected consequences of altering any community of organisms, further research should evaluate the impact of such measures under

    Acute intestinal ischemia is an abdominal emergency occurring in nearly 1% of patients presenting with acute abdomen. The causes can be occlusive or non occlusive. Early diagnosis is important to improve survival rates. In most cases of late or missed diagnosis, the mortality rate from intestinal infarction is very high, with a reported value ranging from 60% to 90%. Multi-detector computed tomography (MDCT) is a fundamental imaging technique that must be promptly performed in all patients with suspected bowel ischemia. Thanks to the new dedicated reconstruction program, its diagnostic potential is much improved compared to the past and currently it is superior to that of any other noninvasive technique. The increased spatial and temporal resolution, high-quality multi-planar reconstructions, maximum intensity projections, vessel probe, surface-shaded volume rending and tissue transition projections make MDCT the gold standard for the diagnosis of intestinal ischemia, with reported sensitivity, specificity, positive and negative predictive values of 64%-93%, 92%-100%, 90%-100% and 94%-98%, respectively. MDCT contributes to appropriate treatment planning and provides important prognostic information thanks to its ability to define the nature and extent of the disease. The purpose of this review is to examine the diagnostic and prognostic role of MDCT in bowel ischemia with special regard to the state of art new reconstruction software.

    To assess the prevalence of human immunodeficiency virus (HIV) and pulmonary tuberculosis (PTB) in the study population in Delta State of Nigeria. Two hundred and five patients suspected of HIV and TB were prospectively studied in Kwale, Agbor and Eku in Delta State of Nigeria from February 2006 to February 2008. Human immunodeficiency virus status was determined using World Health Organization systems II, and Zeihl Nelson staining technique was used for TB screening. A health point prevalence rate of 53.2%, was obtained for HIV, 49.3% for TB, and 16.6% for HIV/TB. The population of HIV positive (p=0.890, p=0.011, p=0.006) and TB positive (p=0.135, p=0.0003, p=0.0001) subjects were statistically significant among the suspected subjects while the HIV/TB positive cases were not statistically significant (p=0.987, p=0.685, p=0.731). Our study showed that HIV and PTB infections remains high in parts of Delta State in Nigeria. (author)

    Full Text Available Tuberculosis infection may remain latent, but the disease is nevertheless a serious public health issue. Various epidemiological studies on pulmonary tuberculosis have considered the spatial component and taken it into account, revealing the tendency of this disease to cluster in particular locations. The aim was to assess the contribution of Knowledge Attitude and Practice (KAP to the distribution of tuberculosis and to provide information for the improvement of the National Tuberculosis Program.We investigated the role of KAP to distribution patterns of pulmonary tuberculosis in Antananarivo. First, we performed spatial scanning of tuberculosis aggregation among permanent cases resident in Antananarivo Urban Township using the Kulldorff method, and then we carried out a quantitative study on KAP, involving TB patients. The KAP study in the population was based on qualitative methods with focus groups.The disease still clusters in the same districts identified in the previous study. The principal cluster covered 22 neighborhoods. Most of them are part of the first district. A secondary cluster was found, involving 18 neighborhoods in the sixth district and two neighborhoods in the fifth. The relative risk was respectively 1.7 (p<10-6 in the principal cluster and 1.6 (p<10-3 in the secondary cluster. Our study showed that more was known about TB symptoms than about the duration of the disease or free treatment. Knowledge about TB was limited to that acquired at school or from relatives with TB. The attitude and practices of patients and the population in general indicated that there is still a stigma attached to tuberculosis.This type of survey can be conducted in remote zones where the tuberculosis-related KAP of the TB patients and the general population is less known or not documented; the findings could be used to adapt control measures to the local particularities.

    A wide variety of disorders affecting the intestinal tract in cattle may require surgery. Among those disorders the more common are: intestinal volvulus, jejunal hemorrhage syndrome and more recently the duodenal sigmoid flexure volvulus. Although general principles of intestinal surgery can be applied, cattle has anatomical and behavior particularities that must be known before invading the abdomen. This article focuses on surgical techniques used to optimize outcomes and discusses specific disorders of small intestine. Diagnoses and surgical techniques presented can be applied in field conditions. Copyright © 2016 Elsevier Inc. All rights reserved.

    Development of rapid diagnostic tests for tuberculosis is a global priority. A whole proteome screen identified Mycobacterium tuberculosis antigens associated with serological responses in tuberculosis patients. We used World Health Organization (WHO) target product profile (TPP) criteria for a detection test and triage test to evaluate these antigens. Consecutive patients presenting to microscopy centers and district hospitals in Peru and to outpatient clinics at a tuberculosis reference center in Vietnam were recruited. We tested blood samples from 755 HIV-uninfected adults with presumptive pulmonary tuberculosis to measure IgG antibody responses to 57 M. tuberculosis antigens using a field-based multiplexed serological assay and a 132-antigen bead-based reference assay. We evaluated single antigen performance and models of all possible 3-antigen combinations and multiantigen combinations. Three-antigen and multiantigen models performed similarly and were superior to single antigens. With specificity set at 90% for a detection test, the best sensitivity of a 3-antigen model was 35% (95% confidence interval [CI], 31-40). With sensitivity set at 85% for a triage test, the specificity of the best 3-antigen model was 34% (95% CI, 29-40). The reference assay also did not meet study targets. Antigen performance differed significantly between the study sites for 7/22 of the best-performing antigens. Although M. tuberculosis antigens were recognized by the IgG response during tuberculosis, no single antigen or multiantigen set performance approached WHO TPP criteria for clinical utility among HIV-uninfected adults with presumed tuberculosis in high-volume, urban settings in tuberculosis-endemic countries. © The Author 2017.

  5. Lineup composition, suspect position, and the sequential lineup advantage.

    2008-06-01

    N. M. Steblay, J. Dysart, S. Fulero, and R. C. L. Lindsay (2001) argued that sequential lineups reduce the likelihood of mistaken eyewitness identification. Experiment 1 replicated the design of R. C. L. Lindsay and G. L. Wells (1985), the first study to show the sequential lineup advantage. However, the innocent suspect was chosen at a lower rate in the simultaneous lineup, and no sequential lineup advantage was found. This led the authors to hypothesize that protection from a sequential lineup might emerge only when an innocent suspect stands out from the other lineup members. In Experiment 2, participants viewed a simultaneous or sequential lineup with either the guilty suspect or 1 of 3 innocent suspects. Lineup fairness was varied to influence the degree to which a suspect stood out. A sequential lineup advantage was found only for the unfair lineups. Additional analyses of suspect position in the sequential lineups showed an increase in the diagnosticity of suspect identifications as the suspect was placed later in the sequential lineup. These results suggest that the sequential lineup advantage is dependent on lineup composition and suspect position. (c) 2008 APA, all rights reserved

    Full Text Available The paper characterizes drug susceptibility in Mycobacterium tuberculosis isolated from new cases of tuberculosis concurrent with HIV infection. The investigators have studied the spectrum of drug resistance in Mycobacterium tuberculosis isolated from new cases of tuberculosis concurrent with and without HIV infection (172 and 309 clinical isolates, respectively. There are differences in the rate of primary drug resistance to antituberculosis drugs in patients with and without HIV infection (59 and 43.5% of the cases, respectively. The HIV-infected have also shown high rifampicin resistance rates in Mycobacterium tuberculosis (41.7%. The reasons for these differences are as yet unknown and call for further investigation.

    CNS infections like meningitis and encephalitis pose enormous healthcare challenges due to mortality, sequelae and socioeconomic burden. In tertiary setting, clinical, microbiological, cytological and radiological investigations are not distinctive enough for diagnosing microbial etiology. Molecular diagnostics is filling this gap. We evaluated the clinical impact of a commercially available multiplex molecular diagnostic system - SES for diagnosing suspected CNS infections. This study was conducted in our tertiary level Neurology ICU. 110 patients admitted during Nov-2010 to April-2014 were included. CSF samples of patients clinically suspected of having CNS infections were subjected to routine investigation in our laboratory and SES test at XCyton Diagnostics. We studied the impact of SES in diagnosis of CNS infections and its efficacy in helping therapeutic management. SES showed detection rate of 42.18% and clinical specificity of 100%. It had 10 times higher detection rate than conventional tests. Streptococcus pneumoniae and Mycobacterium tuberculosis were two top bacterial pathogens. VZV was most detected viral pathogen. SES results elicited changes in therapy in both positive and negative cases. We observed superior patient outcomes as measured by GCS scale. 75% and 82.14% of the patients positive and negative on SES respectively, recovered fully. Detecting causative organism and ruling out infectious etiology remain the most critical aspect for management and prognosis of patients with suspected CNS infections. In this study, we observed higher detection rate of pathogens, target specific escalation and evidence based de-escalation of antimicrobials using SES. Institution of appropriate therapy helped reduce unnecessary use of antimicrobials. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Purpose: Ethambutol (EMB is an important first line drug, however little information on its molecular mechanism of resistance and pathogenicity of resistant isolates is available. Present work was designed to study virulence of the EMB resistant M. tuberculosis strains and the host responses in-vivo on infection of EMB resistant M. tuberculosis using Balb/c mouse model of infection. Methods: Three groups of Balb/c mice (female, age 4-6 wk; 21 mice in each group were infected intravenously with 106 CFU of M. tuberculosis H37Rv and two EMB resistant clinical isolates. Age and sex matched control animals were mock inoculated with Middlebrook 7H9 broth alone. At 10, 20, 30, 40, 50, 60, and 70 days post-infection three animals from each group were sacrificed by cervical dislocation and lung tissue was collected for further analysis. Results: Infection with EMB resistant M. tuberculosis led to progressive and chronic disease with significantly high bacillary load (p=0.02. Massive infiltration and exacerbated lung pathology with increased expression of IFN-γ and TNF-α was observed in lungs of mice infected with EMB resistant strains. The present study suggests that infection with EMB resistant M. tuberculosis leads to chronic infection with subsequent loss of lung function, bacterial persistence with elevated expression of TNF-α resulting in increased lung pathology. Conclusion: These findings highlight that EMB resistant M. tuberculosis regulates host immune response differentially and its pathogenicity is different from drug sensitive strains of M. tuberculosis.

  10. Guidance for National Tuberculosis Programmes on the management of tuberculosis in children. Chapter 1: introduction and diagnosis of tuberculosis in children.

    2006-10-01

    About one million children develop tuberculosis (TB) annually worldwide, accounting for about 11% of all TB cases. Children with TB differ from adults in their immunological and pathophysiological response in ways that may have important implications for the prevention, diagnosis and treatment of TB in children. There is an urgent need to improve the diagnosis and management of children with TB, and the prevention of TB in children, by ensuring their inclusion under the implementation of the Stop TB strategy by National TB Programmes. Critical areas for further research include a better understanding of the epidemiology of childhood TB, vaccine development, the development of better diagnostic techniques, new drug development, and the optimal formulations and dosing of first- and second-line TB drugs in children. Specifically regarding the diagnosis of TB in children, this relies on a careful and thorough assessment of all the evidence derived from a careful history, clinical examination and relevant investigations, e.g., tuberculin skin test, chest radiograph and sputum smear microscopy. Although bacteriological confirmation of TB is not always possible, it should be sought whenever possible, e.g., by sputum microscopy in children with suspected pulmonary TB who are old enough to produce a sputum sample. A trial of treatment with TB medications is not generally recommended as a method to diagnose TB in children. New, improved diagnostic tests are urgently needed.

    To determine the proportional distribution of endobronchial tuberculosis (EBTB) subtypes and to evaluate the types of bronchoscopic diagnostic procedures that can prove granulomatous inflammation. This was a retrospective study of 18 HIV-negative patients with biopsy-proven EBTB treated between 2010 and 2014. The most common EBTB subtypes, as classified by the bronchoscopic features, were tumorous and granular (in 22.2% for both). Sputum smear microscopy was performed in 11 patients and was positive for AFB in 4 (36.3%). Sputum culture was also performed in 11 patients and was positive for Mycobacterium tuberculosis in 10 (90.9%). Smear microscopy of BAL fluid (BALF) was performed in 16 patients and was positive for AFB in 10 (62.5%). Culture of BALF was also performed in 16 patients and was positive for M. tuberculosis in 15 (93.7%). Culture of BALF was positive for M. tuberculosis in 93.7% of the 16 patients tested. Among the 18 patients with EBTB, granulomatous inflammation was proven by the following bronchoscopic diagnostic procedures: bronchial mucosal biopsy, in 8 (44.4%); bronchial brushing, in 7 (38.8%); fine-needle aspiration biopsy, in 2 (11.1%); and BAL, in 2 (11.1%). Bronchial anthracofibrosis was observed in 5 (27.7%) of the 18 cases evaluated. In our sample of EBTB patients, the most common subtypes were the tumorous and granular subtypes. We recommend that sputum samples and BALF samples be evaluated by smear microscopy for AFB and by culture for M. tuberculosis, which could increase the rates of early diagnosis of EBTB. We also recommend that bronchial brushing be employed together with other bronchoscopic diagnostic procedures in patients suspected of having EBTB.

    Owing to the devastation caused by tuberculosis along with the unsatisfactory performance of the Bacillus Calmette–Guérin (BCG) vaccine, a more efficient vaccine than BCG is required for the global control of tuberculosis. A number of studies have demonstrated an essential role of biotin biosynthesis in the growth and survival of several microorganisms, including mycobacteria, through deletion of the genes involved in de novo biotin biosynthesis. In this study, we demonstrate that a bioA mutant of Mycobacterium tuberculosis (MtbΔbioA) is highly attenuated in the guinea pig model of tuberculosis when administered aerogenically as well as intradermally. Immunization with MtbΔbioA conferred significant protection in guinea pigs against an aerosol challenge with virulent M. tuberculosis, when compared with the unvaccinated animals. Booster immunization with MtbΔbioA offered no advantage over a single immunization. These experiments demonstrate the vaccinogenic potential of the attenuated M. tuberculosis bioA mutant against tuberculosis. PMID:28658275

    Tuberculosis remains a major health problem in India, with 2 million new cases and 421,000 deaths each year. In this paper, we describe the spoligotyping results of 216 Mycobacterium tuberculosis culture isolates from patients with pulmonary tuberculosis in Mumbai, India. As spoligotyping data from India have rarely been described until now, and as there is limited information on the major circulating clades of M. tuberculosis, the data obtained were also compared to an international spoligotype database (SpolDB4) that contained patterns from 22,546 isolates from more than 100 countries. Eighty-four (39%) of the isolates were definitively marked as orphan strains, indicating the paucity of such data from India. The remaining 132 isolates clustered among 59 shared types; among these, 42 shared types were already present in the database, 17 were newly created, and 5 of them were specifically reported from Mumbai. A total of 9 major types in this study clustered 32% of the isolates. At the phylogenetic level, 30% of the isolates belonged to the Central Asian families CAS1 and CAS2, of the major genetic group (MGG) 1, 29% to MGG 2 and 3 families (spacers 33-36 missing) and 17% to the ancestral East African Indian (EAI) family. Finally, nearly 10% of the isolates belonged to the W-Beijing family in a broad sense, also in the MGG 1 group. In conclusion, historic clones of the MGG 1 group of M. tuberculosis are responsible for roughly 60% of all tuberculosis cases in Mumbai. Together with the fact that organisms presumably of European descent (such as the Haarlem family) were only rarely found, our observations suggest that tuberculosis in Mumbai, India is essentially caused by historical clones of tubercle bacilli undergoing active circulation due to uncontrolled demography, high prevalence of the disease, and a paucity of resources.

    Background. The differential diagnosis of primary breast tuberculosis with other benign or malignant conditions can be difficult with the current imaging techniques that used to recognize breast pathologies. In many cases mammographic and ultrasound characteristics of breast tuberculosis are similar to those of breast cancer. Case report. We present a case of primary breast tuberculosis, with no previous history of the disease, which was diagnosed during the operation. Conclusions. Primary breast tuberculosis can be misdiagnosed. In these cases a tuberculosis infection history is negative, the mammographic and radiological findings obscure and the mass can be misdiagnosed as carcinoma. The diagnosis is achieved after the surgical removal of the mass and histological examination of the specimen. (author)

    Low–molecular-weight metabolites produced by intestinal microbiota play a direct role in health and disease. In this study, we analyzed the colonic luminal metabolome using capillary electrophoresis mass spectrometry with time-of-flight (CE-TOFMS) —a novel technique for analyzing and differentially displaying metabolic profiles— in order to clarify the metabolite profiles in the intestinal lumen. CE-TOFMS identified 179 metabolites from the colonic luminal metabolome and 48 metabolites were present in significantly higher concentrations and/or incidence in the germ-free (GF) mice than in the Ex-GF mice (p metabolome and a comprehensive understanding of intestinal luminal metabolome is critical for clarifying host-intestinal bacterial interactions.

    Two decades ago, WHO declared tuberculosis a global emergency, and invested in the highly cost-effective directly observed treatment short-course programme to control the epidemic. At that time, most strains of Mycobacterium tuberculosis were susceptible to first-line tuberculosis drugs, and drug resistance was not a major issue. However, in 2013, tuberculosis remains a major public health concern worldwide, with prevalence of multidrug-resistant (MDR) tuberculosis rising. WHO estimates roughly 630 000 cases of MDR tuberculosis worldwide, with great variation in the frequency of MDR tuberculosis between countries. In the past 8 years, extensively drug-resistant (XDR) tuberculosis has emerged, and has been reported in 84 countries, heralding the possibility of virtually untreatable tuberculosis. Increased population movement, the continuing HIV pandemic, and the rise in MDR tuberculosis pose formidable challenges to the global control of tuberculosis. We provide an overview of the global burden of drug-resistant disease; discuss the social, health service, management, and control issues that fuel and sustain the epidemic; and suggest specific recommendations for important next steps. Visionary political leadership is needed to curb the rise of MDR and XDR tuberculosis worldwide, through sustained funding and the implementation of global and regional action plans.

    Objective: To find out the average duration from onset of symptoms to the diagnosis and treatment of tuberculosis, reasons for diagnostic delay, its consequences, association of variables and formulation of recommendations. Results: In this study it was found that average time from onset of initial symptoms to diagnosis and treatment of tuberculosis was 120 days. In 64% of the patients medical practitioners were responsible for delaying the diagnosis of tuberculosis. Loss of weight in 40% and haemoptysis is 21% were the consequences of diagnostic delay of tuberculosis. Delay in the diagnosis of tuberculosis was statistically significant in those patients who consulted private practitioners, and consequences of tuberculosis were severe in those patients who consulted late.

    Background. Recurrent tuberculosis disease occurs within 2 years in as few as 1% and as many as 29% of individuals successfully treated for multidrug-resistant (MDR) tuberculosis. A better understanding of treatment-related factors associated with an elevated risk of recurrent tuberculosis after cure is urgently needed to optimize MDR tuberculosis therapy. Methods. We conducted a retrospective cohort study among adults successfully treated for MDR tuberculosis in Peru. We used multivariable Cox proportional hazards regression analysis to examine whether receipt of an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion from positive to negative was associated with a reduced rate of recurrent tuberculosis. Results. Among 402 patients, the median duration of follow-up was 40.5 months (interquartile range, 21.2–53.4). Receipt of an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion was associated with a lower risk of recurrent tuberculosis (hazard ratio, 0.40 [95% confidence interval, 0.17–0.96]; P = .04). A baseline diagnosis of diabetes mellitus also predicted recurrent tuberculosis (hazard ratio, 10.47 [95% confidence interval, 2.17–50.60]; P = .004). Conclusions. Individuals who received an aggressive MDR tuberculosis regimen for ≥18 months following sputum conversion experienced a lower rate of recurrence after cure. Efforts to ensure that an aggressive regimen is accessible to all patients with MDR tuberculosis, such as minimization of sequential ineffective regimens, expanded drug access, and development of new MDR tuberculosis compounds, are critical to reducing tuberculosis recurrence in this population. Patients with diabetes mellitus should be carefully managed during initial treatment and followed closely for recurrent disease. PMID:23223591

    Full Text Available Prostate tuberculosis is difficult to be diagnosed, especially if lesions are limited only by this organ. The article analyses the experience of differential diagnostics of prostate tuberculosis based on the data of examination of 84 patients. 45 of them were diagnosed with prostate tuberculosis, and 39 patients were diagnosed with chronic bacterial prostatitis. Pathognomonic diagnostics criteria of prostate tuberculosis were the following: detection of tuberculous mycobacteria in the prostatic fluid or ejaculate, signs of granulomatous prostatitis with areas of cavernous necrosis in prostate biopsy samples, and prostate cavities visualized by X-ray or ultrasound examinations. Should the above criteria be absent, the disease can be diagnosed based on the combination of indirect signs: symptoms of prostate inflammation with active tuberculosis of the other localization; large prostate calcification, extensive hyperechoic area of the prostate, spermatocystic lesions, leucospermia and hemospermia, failure of the adequate non-specific anti-bacterial therapy.

    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

  7. Extrathoracic manifestations of tuberculosis

    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.

From June 2011 to June 2014, 48 patients with active pulmonary tuberculosis induced by Mycobacterium tuberculosis were included in the study. In addition, 23 healthy subjects were enrolled as control. Macrophages were collected by pulmonary alveolus lavage. In addition, serum and mononuclear cells were isolated from peripheral blood. The levels of miR-365 and IL-6 in macrophages, mononuclear cells and serum were determined using quantitative real-time polymerase chain reaction. The protein expression of IL-6 in macrophages and mononuclear cells was measured using Western blotting, while that in serum was detected by enzyme-linked immunoabsorbent assay. Expression of IL-6 mRNA and protein was significantly enhanced in patients with active pulmonary tuberculosis. Increase of IL-6 protein concentration in serum was probably due to the release of IL-6 protein from mononuclear cells in the blood. In addition, miR-365 levels were significantly lowered in patients with active pulmonary tuberculosis. Up-regulated IL-6 expression in macrophages, mononuclear cells and serum in patients with active pulmonary tuberculosis is related to the down-regulation of miR-365, suggesting that miR-365 may regulate the occurrence and immune responses of active pulmonary tuberculosis via IL-6.

    A more effective vaccine to control tuberculosis (TB), a major global public health problem, is urgently needed. Current vaccine candidates focus predominantly on eliciting cell-mediated immunity but other arms of the immune system also contribute to protection against TB. We review here recent studies that enhance our current knowledge of antibody-mediated functions against Mycobacterium tuberculosis. These findings, which contribute to the increasing evidence that antibodies have a protective role against TB, include demonstrations that firstly distinct human antibody Fc glycosylation patterns, found in latent M. tuberculosis infection but not in active TB, influence the efficacy of the host to control M. tuberculosis infection, secondly antibody isotype influences human antibody functions, and thirdly that antibodies targeting M. tuberculosis surface antigens are protective. We discuss these findings in the context of TB vaccine development and highlight the need for further research on antibody-mediated immunity in M. tuberculosis infection.

    In Vietnam, the Mycobacterium tuberculosis Beijing genotype is associated with multi-drug resistance and is emerging. A possible explanation for this genotype's success is an increased rate of relapse. In a prospective cohort study, isolates from patients with smear-positive tuberculosis were

    Mycobacterium tuberculosis strains of the Beijing genotype have been involved in various outbreaks of multidrug-resistant tuberculosis. Some studies suggest that the infection with the Beijing genotype is associated with a different host immune response. Since this might also lead to a different

    Attitudes towards tuberculosis may have severe impact on individuals and their families as well as on the effectiveness of tuberculosis control programs. The purpose of this study was to describe these attitudes and explore the sources of tuberculosis information available to the general population in Croatia through a cross-sectional survey based on structured questionnaire using convenience sampling among 386 subjects aged 18 years and over. Data were stratified by sex, age groups, educational background, personal monthly income and contact with tuberculosis patient. Being near to a tuberculosis patient would be uncomfortable for 39.9% of respondents and 26.4% of subjects would avoid any contact. If they were sick of tuberculosis, 9.6% of respondents would keep it from the society. Less than 10% of study subjects would be ashamed of their own or potential tuberculosis in their family. Almost twice less subjects with high education would hide the disease (P=0.049), or be ashamed if sick in comparison with less educated respondents (P=0.036). The subjects who were not in contact were less likely to feel uncomfortable about being near to a tuberculosis patient (P=0.042). As the source of tuberculosis information, 61% of the subjects reported TV, radio and journals. Internet was the least used source (13.2%). The subjects in contact received information from the family or friends (P=0.025), while those without contact were informed through mass media (P<0.001). Study results revealed high stigma-generating attitudes towards tuberculosis. The strong potential of mass media capable of reaching different population groups should be used as part of the stigma-reduction strategies.

    Two experiments directly compare two methods of selecting foils for identification lineups. The suspect-matched method selects foils based on their match to the suspect, whereas the description-matched method selects foils based on their match to the witness's description of the perpetrator. Theoretical analyses and previous results predict an advantage for description-matched lineups both in terms of correctly identifying the perpetrator and minimizing false identification of innocent suspects. The advantage for description-matched lineups should be particularly pronounced if the foils selected in suspect-matched lineups are too similar to the suspect. In Experiment 1, the lineups were created by trained police officers, and in Experiment 2, the lineups were constructed by undergraduate college students. The results of both experiments showed higher suspect-to-foil similarity for suspect-matched lineups than for description-matched lineups. However, neither experiment showed a difference in correct or false identification rates. Both experiments did, however, show that there may be an advantage for suspect-matched lineups in terms of no-pick and rejection responses. From these results, the endorsement of one method over the other seems premature.

  16. Neutrophils in Tuberculosis: Heterogeneity Shapes the Way?

    Science.gov (United States)

    2017-01-01

    Infection with M. tuberculosis remains one of the most common infections in the world. The outcome of the infection depends on host ability to mount effective protection and balance inflammatory responses. Neutrophils are innate immune cells implicated in both processes. Accordingly, during M. tuberculosis infection, they play a dual role. Particularly, they contribute to the generation of effector T cells, participate in the formation of granuloma, and are directly involved in tissue necrosis, destruction, and infection dissemination. Neutrophils have a high bactericidal potential. However, data on their ability to eliminate M. tuberculosis are controversial, and the results of neutrophil depletion experiments are not uniform. Thus, the overall roles of neutrophils during M. tuberculosis infection and factors that determine these roles are not fully understood. This review analyzes data on neutrophil defensive and pathological functions during tuberculosis and considers hypotheses explaining the dualism of neutrophils during M. tuberculosis infection and tuberculosis disease.

    Full Text Available La evolución etiológica de la medicina la podemos dividir en dos grandes períodos: período de la sífilis y período de la tuberculosis. El período de la sífilis, gracias a las armas de combate de que hoy disponemos, ocupa un lugar secundario. El período de la tuberculosis y que no es sino el paralelo de la vida moderna, ocupa en vigencia el primer lugar. Es el período presente. 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.

    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.

    Despite concerted efforts to scale up tuberculosis control with large amounts of international financing in the last 2 decades, tuberculosis continues to be a social issue affecting the world's most marginalized and disadvantaged communities. This includes prisoners, estimated at about 10 million globally, for whom tuberculosis is a leading cause of mortality and morbidity. The Global Fund to Fight AIDS, Tuberculosis and Malaria has emerged as the single largest international donor for tuberculosis control, including funding support in delivering tuberculosis treatment for the confined population. The Global Fund grants database, with an aggregate approved investment of $21.7 billion in 150 countries by the end of 2010, was reviewed to identify tuberculosis and human immunodeficiency virus/tuberculosis grants and activities that monitored the delivery of tuberculosis treatment and support activities in penitentiary settings. The distribution and trend of number of countries with tuberculosis prison support was mapped by year, geographic region, tuberculosis or multidrug-resistant tuberculosis burden, and prison population rate. We examined the types of grant recipients managing program delivery, their performance, and the nature and range of services provided. Fifty-three of the 105 countries (50%) with Global Fund-supported tuberculosis programs delivered services within prison settings. Thirty-two percent (73 of 228) of tuberculosis grants, representing $558 million of all disbursements of Global Fund tuberculosis support by the end of 2010, included output indicators related to tuberculosis services delivered in prisons. Nearly two-thirds (64%) of these grants were implemented by governments, with the remaining by civil society and other partners. In terms of services, half (36 of 73) of grants provided diagnosis and treatment and an additional 27% provided screening and monitoring of tuberculosis for prisoners. The range of services tracked was limited in scope
