    Full Text Available Abstract Introduction Osseous tuberculosis can be present with unifocal or multifocal bony involvement. Although multifocal involvement of the skeletal system in areas where tuberculosis is endemic is not a rare presentation, its exact prevalence is not well known. A case of atypical skeletal tuberculosis mimicking multiple secondary metastases on radiologic and scintigraphic imaging is presented to emphasize the contribution of bone scintigraphy in the assessment of osseous tuberculosis in typical and atypical presentations. Case presentation A 73-year-old cachectic Asian man (Iranian presented with a general feeling of being unwell and an acute loss of vision in his left eye accompanied by a severe headache. A Tc-99 m-methylene diphosphonate bone scan demonstrated multiple regions of intense activity in the appendicular and axial skeleton, suggesting metastatic involvement. Tumor markers (PSA, CA125, CA 19-9 and AFP were within normal ranges. Based on clinical presentation and laboratory, radiological and scintigraphic findings, a presumptive diagnosis of tuberculosis was made. Quadruple antituberculous chemotherapy was consequently started and the patient later showed marked improvement. Conclusion Scintigraphic bone scanning should be kept in mind when assessing bone pain in patients at a high risk of tuberculosis infection or reactivation. We present this unusual case of multifocal skeletal tuberculosis, and stress the related clinical and diagnostic points with the aim of stimulating a high index of suspicion that could facilitate early diagnosis and appropriate treatment.

  2. Skeletal tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis remains a major cause of bone and joint infection, and its frequency has been increasing during recent years. Recent imaging methods, especially MR, are necessary for the early diagnosis of the disease, because conventional radiography may fail to reveal the initial osseous lesions. Spine is the most common site of infection, with relatively characteristic features; MR is the most suitable method for evaluation of bone involvement, paravertebral and epidural abscesses. Radiographic presentation of tuberculous osteitis and osteo-arthritis is less characteristic. The final diagnosis frequently needs histological studies and cultures of bone, synovial tissue or synovial fluid. (authors)., 13 figs., 35 refs

    Tuberculosis of the skeletal muscle is very rare which is often missed in the early stages. This leads to delay in treatment resulting in irreversible limb deformity and loss of function. The authors describe a case of healthy child with an intramuscular cystic swelling above the elbow joint. The pus showing acid fast bacilli morphologically resembling Mycobacterium tuberculosis was also isolated in culture. Following the diagnosis and confirmation, the child was treated successfully with anti tubercular drugs. PMID:20890682

    This is a case report of spinal tuberculosis combined with sacroiliac joint tuberculosis, pulmonary tuberculosis, chest wall tuberculosis and tuberculous pleurisy and the image of the patient is rare, special and not typical and it looks like a halo sign. It has an important reference value for the diagnosis of spine tuberculosis although it is a rare imaging manifestation and diagnosis was confirmed by pathology after the surgery. Therefore atypical imaging is often appeared in clinical practice and it is meaningful and necessary for the diagnosis of atypical spinal tuberculosis combined with multiple organ tuberculosis.

    Tuberculosis involving the soft tissue from adjacent bone or joint is well recognized. However, primary tuberculous pyomyositis, tuberculous bursitis, and tuberculous tenosynovitis are rare entities constituting 1% of skeletal tuberculosis. Tuberculosis tenosynovitis involves most commonly the tendon sheaths of the hand and wrist, and tuberculous bursitis occurs most commonly around the hip. The greater trochanteric bursa and the greater trochanter are the most frequent sites of tuberculous bursitis. Cases of primary tuberculous pyomyositis and tenosynovitis of the tendons of the ankle and foot are seldom reported in the radiology literature. All imaging modalities - plain radiography, bone scan, computed tomography, and magnetic resonance imaging (MRI) - provide information that is helpful in determining therapy. MRI in particular, with its multiplanar capabilities and superb contrast of soft tissue, can demonstrate the extent of the soft tissue mass and access the adjacent bones and joints. However, MRI has no diagnostic specificity in regard to tuberculosis, and in nonendemic areas, biopsy is strongly recommended. All patients in this review were permanent residents of North America or Western Europe and were immunocompetent. Examples of atypical presentations of the above entities are demonstrated. (author)

    Full Text Available Tuberculosis, one of the oldest diseases known to affect humans is caused by the bacteria mycobacterium tuberculosis. The disease usually affects the lungs, although, in up to one third of cases, other organs are involved. Metastatic tuberculosis abscess is a rare form of skin tuberculosis. It is characterized by nodule and abscess formation throughout the body after hematogenous spread of mycobacterium tuberculosis from a primary focus during a period of impaired immunity. Tuberculosis osteomyelitis is also a rare form of extrapulmonary tuberculosis in pediatric age group. Skeletal tuberculosis pathogenesis is related to reactivation of hematogenous foci or spread from adjacent paravertebral lymph nodes. Weight-bearing joints are affected most commonly. Bilateral hand and foot bone involvement is rarely reported. We present a five-year-old girl with two very rare presentations of the disease such as osteomyelitis and metastatic skin abscess.

    Skeletal tuberculosis is an important component of extra-pulmonary tuberculosis. It can lead to substantial morbidity and poses serious occupational and economic problem. We conducted a study in an urban District Tuberculosis Centre (DTC) to assess the burden and distribution of skeletal tuberculosis in the community. Our centre was catering to a population of 6-7 lakhs between 2007 and 2012. During this period, we treated 11,274 cases of tuberculosis. Out of these, 3086 (27.3%) were cases of extrapulmonary tuberculosis and 219 (1.94%) were cases of skeletal tuberculosis. Skeletal TB predominantly affects the young Indian population with incidence peaking in the second and third decades of life. 172 patients (78.5%) in our study were new cases. There were no drugs resistant (DRTB) skeletal TB cases till we concluded our study. Tuberculosis commonly involves joints more than long bones. The spinal column was the most commonly involved skeletal site affecting 62.6% of all cases. The rate of spinal TB in our study is much higher than that reported in literature. The high number of patients calls for close co-ordination between managing orthopaedic surgeons, treating physicians and DOT providers to ensure adequate patient care. PMID:27451817

    We present a case of atypical osseous tuberculosis mimicking multiple secondary metastases on radiological and nuclear imaging. A multi-bacterial spondylitis of Ti was first diagnosed on a 56 year-old patient presenting with dorsal pain and neurological deficit of the left arm (fine needle aspiration was negative for Mycobacterium tuberculosis). Whole-body bone scintigraphy identified additional sites, including an asymptomatic sacroiliac lesion, which was accessible to biopsy that gave the final diagnosis of osseous tuberculosis. We propose, in the discussion, a practical review of imaging patterns in cases of typical or atypical osseous tuberculosis. (author)

    A 27 year-old lady, presented with sudden loss of vision in the right eye for a week. It was followed by poor vision in the left eye after 3 days. It involved the whole entire visual field and was associated with pain on eye movement. She was diagnosed to have miliary tuberculosis and retroviral disease 4 months ago. She was started on anti-TB since then but defaulted highly active anti-retroviral therapy (HAART). On examination, her visual acuity was no perception of light in the right eye and 6/120 (pinhole 3/60) in the left eye. Anterior segment in both eyes was unremarkable. Funduscopy showed bilateral optic disc swelling with presence of multiple foci of choroiditis in the peripheral retina. The vitreous and retinal vessels were normal. Chest radiography was normal. CT scan of orbit and brain revealed bilateral enhancement of the optic nerve sheath that suggest the diagnosis of bilateral atypical optic neuritis. This patient was managed with infectious disease team. She was started on HAART and anti-TB treatment was continued. She completed anti-TB treatment after 9 months without any serious side effects. During follow up the visual acuity in both eyes was not improved. However, funduscopy showed resolving of disc swelling and choroiditis following treatment.

  15. Tuberculosis the great mimicker: 18F-fludeoxyglucose positron emission tomography/computed tomography in a case of atypical spinal tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis (TB) has aptly been called the great mimicker. A 14-year-old boy, who had been treated for Hodgkin's Lymphoma 2 years back and had been in remission, underwent a whole body 18F-fludeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan, owing to a recent onset of backache and difficulty in walking. The study showed an FDG avid destructive lesion of the posterior elements of the sixth, seventh and eighth dorsal vertebrae along with a hypermetabolic collection in the adjacent paraspinal muscles with extension into the spinal canal, causing encasement of the thecal sac as well. Based on this constellation of findings, a diagnosis of atypical spinal TB was made, which was subsequently proven on histopathology. The present case illustrates that spinal TB, including the atypical form can be diagnosed on PET/CT even in clinically unsuspected cases

    Paradoxical reactions like immune reconstitution inflammatory syndrome (IRIS) as seen with patients on retroviral treatment in HIV infection, have also been identified in HIV sero-negative patients with extra pulmonary tuberculosis especially lymph-node tuberculosis. Musculo-skeletal tuberculosis presenting as a cold abscess of the anterior chest wall is a rare entity which poses diagnostic and therapeutic challenge. A 35-year-old immunocompetent male came with complains of painless lump on right side of his chest over 9th and 10th intercostal space which gradually increased and extended upto 11th rib area. Clinically, diagnosis of cold abscess was made and anti-tubercular therapy (ATT) was started. Despite of being on ATT for 3 weeks, patient developed pain and signs of inflammation. Fluid was aspirated and sent for biochemical and microbiological investigations. The aspirated fluid was positive for acid fast bacilli by ZN stain and grew Mycobacterium tuberculosis in culture, sensitive to first line ATT. Pyogenic and fungal culture was negative. This case presented as an anterior chest wall cold abscess which deteriorated on initiation of first line ATT, thus creating a suspicion of resistance to ATT which was cleared on ATT susceptibility testing. Hence, this case underlines the possibility of treatment paradoxes seen in immunocompetent musculo-skeletal tuberculosis. PMID:26046019

    The amyloidotic form of bovine spongiform encephalopathy (BSE) termed BASE is caused by a prion strain whose biological properties differ from those of typical BSE, resulting in a clinically and pathologically distinct phenotype. Whether peripheral tissues of BASE-affected cattle contain infectivity is unknown. This is a critical issue since the BASE prion is readily transmissible to a variety of hosts including primates, suggesting that humans may be susceptible. We carried out bioassays in transgenic mice overexpressing bovine PrP (Tgbov XV) and found infectivity in a variety of skeletal muscles from cattle with natural and experimental BASE. Noteworthy, all BASE muscles used for inoculation transmitted disease, although the attack rate differed between experimental and natural cases (∼70% versus ∼10%, respectively). This difference was likely related to different prion titers, possibly due to different stages of disease in the two conditions, i.e. terminal stage in experimental BASE and pre-symptomatic stage in natural BASE. The neuropathological phenotype and PrP(res) type were consistent in all affected mice and matched those of Tgbov XV mice infected with brain homogenate from natural BASE. The immunohistochemical analysis of skeletal muscles from cattle with natural and experimental BASE showed the presence of abnormal prion protein deposits within muscle fibers. Conversely, Tgbov XV mice challenged with lymphoid tissue and kidney from natural and experimental BASE did not develop disease. The novel information on the neuromuscular tropism of the BASE strain, efficiently overcoming species barriers, underlines the relevance of maintaining an active surveillance.

    Full Text Available Tuberculosis of spine is common in a developing country like India. However, involvement of spine at multiple levels along with involvement of rib and tubercular breast abscess in an immunocompetent patient without any pulmonary involvement is extremely rare. Here we report a case of 53-year-old immunocompetent lady who presented with quadriparesis and MRI (magnetic resonance imaging of spine revealed multiple lesions involving cervical, thoracic, lumbar, and sacral region without any involvement of intervertebral disc. On detailed examination she was found to have a lump in right breast. Fine needle aspiration cytology of both paravertebral collection and breast lump revealed presence of acid fast bacilli. She was put on antitubercular drug for one year and she responded well to therapy.

    Introduction: Multifocal skeletal tuberculosis is a rare condition that may masquerade as Langerhans cell histiocytosis, especially in children. Case Presentation: We report a case of multifocal osseous tuberculosis in a 5-year-old female patient admitted to our hospital with a complaint of low back pain but no history of respiratory symptoms or malaise. Radiological findings included vertebra plana and multiple lytic lesions in both the frontal and pelvic bones. An initial diagnosis of Langerhans cell histiocytosis was made based on imaging findings; however, the patient underwent further evaluation for Mycobacterium tuberculosis, and histopathologic findings confirmed the diagnosis of tuberculosis. The patient showed a nearly complete response after receiving a course of anti-tuberculosis drugs. Conclusions: A high index of suspicion is required for the early diagnosis and prompt treatment of patients with osseous tuberculosis. Given the high prevalence of tuberculosis in developing countries, tuberculosis should be considered in the differential diagnosis of multifocal lytic lesions and vertebra plana, especially in children.

    Although the worldwide incidence of tuberculosis has been slowly decreasing, the global disease burden remains substantial (∼9 million cases and ∼1·5 million deaths in 2013), and tuberculosis incidence and drug resistance are rising in some parts of the world such as Africa. The modest gains achieved thus far are threatened by high prevalence of HIV, persisting global poverty, and emergence of highly drug-resistant forms of tuberculosis. Tuberculosis is also a major problem in health-care workers in both low-burden and high-burden settings. Although the ideal preventive agent, an effective vaccine, is still some time away, several new diagnostic technologies have emerged, and two new tuberculosis drugs have been licensed after almost 50 years of no tuberculosis drugs being registered. Efforts towards an effective vaccine have been thwarted by poor understanding of what constitutes protective immunity. Although new interventions and investment in control programmes will enable control, eradication will only be possible through substantial reductions in poverty and overcrowding, political will and stability, and containing co-drivers of tuberculosis, such as HIV, smoking, and diabetes.

  7. A case of skeletal tuberculosis and psoas abscess: disease activity evaluated using 18 F-fluorodeoxyglucose positron emission tomography-computed tomography

    International Nuclear Information System (INIS)

    Psoas abscess complicating tuberculous spondylitis is a rare morbidity in extrapulmonary tuberculosis. There are no established guidelines for evaluating the clinical response of psoas abscess. Although several studies have shown that positron emission tomography-computed tomography with 18 F-fluorodeoxyglucose can play a potential role in diagnosing multifocal tuberculosis and monitoring the clinical response of pulmonary tuberculosis, to our knowledge, this is the first report demonstrating that positron emission tomography-computed tomography is useful for evaluating local inflammation and disease activity of a tuberculous psoas abscess. We report a case of multifocal bone and lymph node tuberculosis with concomitant lumbar psoas abscess in a 77-year-old man, along with a literature review. An initial positron emission tomography-computed tomography scan showed intense 18 F-fluorodeoxyglucose accumulation in the sternum, ribs, vertebrae, and lymph nodes. The patient was successfully treated with antitubercular agents and computed tomography-guided drainage therapy. A follow-up positron emission tomography-computed tomography after abscess drainage and 9 months of antitubercular drug treatment revealed that the majority of lesions improved; however, protracted inflammation surrounding the psoas abscess was still observed. These results indicate that disease activity of psoas abscess can remain, even after successful drainage and antitubercular medication regime of appropriate duration. We have successfully followed up the extent of skeletal tuberculosis complicated with psoas abscess by positron emission tomography-computed tomography. In this patient, positron emission tomography-computed tomography is useful for evaluating the disease activity of tuberculous psoas abscess and for assessing the appropriate duration of antitubercular drug therapy in psoas abscess

    The role of new bone formation on visceral surfaces of ribs in the diagnosis of tuberculosis (TB) in past human populations has been explored by many researchers, using both skeletal remains with known causes of death and archaeological samples. This study focuses, firstly, on adult skeletons from the Coimbra Identified Skeletal Collection in Portugal and investigates the skeletal manifestations of individuals known to have died from TB; secondly, this study focuses on the role of rib lesions in the diagnostic criteria for TB. One hundred and fifty-seven males and 106 females aged between 22-87 years were examined; causes of death were assigned as pulmonary TB, extrapulmonary TB, and pulmonary non-TB; a control group, extrapulmonary non-TB, was selected from the remaining individuals. Of individuals with rib lesions, 85.7% (69/81) had pulmonary or extrapulmonary TB as an assigned cause of death, while 17.8% (16/90) of individuals with rib lesions had a non-TB cause of death. Rib lesions were significantly more common in individuals who had died from TB, although the lesions cannot be considered pathognomonic for TB. In individuals dying from pulmonary TB, ribs in the central part of the rib cage were most affected, at their vertebral ends. The lower part of the rib cage may be a marker for peritoneal TB, and "coral-like" new bone formation on ribs may be an indicator of neoplastic disease. Further work on rib involvement in TB in clinical contexts, and the study of further documented skeletal collections, are recommended.

    Full Text Available Atypical depression is defined as a specifier of major depressive disorder. Columbia criteria for atypical depression are commonly used to make a diagnosis. Female sex, onset at early age, chronic course, and higher rate of comorbidity (especially anxiety disorder and bipolar disorder is noteworthy in atypical depression. Although, the atypical depression seems to support the familial genetic transition, there is not any specific study supporting these data. In the treatment of atypical depression, monoamine oxidase inhibitors are reported to be more effective than tricyclic antidepressants. In recent studies, selective serotonin reuptake inhibitors have also proven to be efficient.

    Full Text Available Abstract Introduction Diagnosis of atypical tuberculosis is difficult. Therefore, it is important that physicians are aware of rare presentations of tuberculosis to avoid diagnostic delays. Case presentation We present the case of a 17-year-old Sri Lankan man who presented to our facility with an ill-defined large induration over the skin of his left buttock and thigh. A cause could not be found despite extensive investigations. He also complained of chronic knee pain, but this was not investigated further at the time due to spontaneous resolution. Three years later his knee disease flared up again, with pain, swelling and restriction of movement. A synovial biopsy was suggestive of tuberculosis. He was started on antituberculosis therapy, to which he responded well. Our patient was asymptomatic two months after completion of therapy without any subsequent flare-ups. A chest roentgenogram taken on his second presentation showed evidence of tuberculosis sequelae in his lungs. The most likely diagnosis for the buttock and thigh swelling, when considering the entire clinical picture, is a tuberculous abscess. The constellation of skin and skeletal symptoms and pulmonary tuberculosis is a rare occurrence in an immunocompetent individual, but cases have been reported. Conclusions This case demonstrates the different presentations and the diagnostic difficulties posed by atypical manifestations of tuberculosis. It also demonstrates the value of maintaining a high degree of suspicion in endemic areas, even in the absence of microbiological evidence.

    Occurrence of eclampsia before 20 weeks of pregnancy and after 48 hours of delivery in the absence of typical signs of hypertension and or proteinuria is termed as atypical eclampsia. Atypical or non-classic eclampsia will have some symptoms of eclampsia but without the usual proteinuria or hypertension. All patients with atypical onset should undergo neurological evaluation to rule out neurologic causes of seizures. Cerebral tuberculosis is a rare and serious form of disease secondary to haematogenous spread of Mycobacterium tuberculosis. Here we present a case of cerebral tuberculoma with seizures in late pregnancy mimicking eclampsia. PMID:27504359

  12. Imaging of pulmonary tuberculosis

    International Nuclear Information System (INIS)

    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.)

  13. Imaging of musculoskeletal tuberculosis

    International Nuclear Information System (INIS)

    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 (TB) remains one of the world's most lethal infectious diseases. Preventive and control strategies among other high-risk groups, such as the elderly population, continues to be a challenge. Clinical features of TB in older adults may be atypical and confused with age-related diseases. Diagnosis and management of TB in the elderly person can be difficult; treatment can be associated with adverse drug reactions. This article reviews the current global epidemiology, pathogenesis, clinical characteristics, diagnosis, management, and prevention of Mycobacterium tuberculosis infection in community-dwelling and institutionalized aging adults.

    Full Text Available Tuberculosis is a leading cause of morbidity and mortality in developing countries including India. Skeletal tuberculosis accounts for 1-3%. Tuberculosis of bone may evade the diagnosis for a long time, as it usually remains silent till either involvement of a neighbouring joint or development of a soft tissue swelling due to cold abscess formation. Tuberculosis of bone mimics clinical conditions like Chronic Osteomyelitis, Madura mycosis and Actinomycosis. There have been few case reports of unusual sites being affected and with unusual presentation by this disease.

    2002-10-01

    Full Text Available Tuberculosis is an extremely common chronic disease in developing countries, caused by Mycobacterium tuberculosis. The principal target organ is the lung, causing focal necrosis and destruction. In about 12% of cases, extrapulmonary dissemination involving the gastrointestinal system occurs. The pancreas is involved in about 0,25% of all cases of disseminated tuberculosis, but its isolated involvement is a medical curiosity. In the last years, with the advent of AIDS, extrapulmonary dissemination and atypical abdominal presentation has increased. We report a case of pancreatic tuberculosis in a 66-year-old patient, with no previous history of pulmonary tuberculosis or immunocompromised state in whom the diagnosis was made by CT-guided skin needle biopsy. After clinical treatment with current antibiotic therapy, the patient recovered well.

    International Nuclear Information System (INIS)

    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.)

  10. Rv2969c, essential for optimal growth in Mycobacterium tuberculosis, is a DsbA-like enzyme that interacts with VKOR-derived peptides and has atypical features of DsbA-like disulfide oxidases

    The gene product of M. tuberculosis Rv2969c is shown to be a disulfide oxidase enzyme that has a canonical DsbA-like fold with novel structural and functional characteristics. The bacterial disulfide machinery is an attractive molecular target for developing new antibacterials because it is required for the production of multiple virulence factors. The archetypal disulfide oxidase proteins in Escherichia coli (Ec) are DsbA and DsbB, which together form a functional unit: DsbA introduces disulfides into folding proteins and DsbB reoxidizes DsbA to maintain it in the active form. In Mycobacterium tuberculosis (Mtb), no DsbB homologue is encoded but a functionally similar but structurally divergent protein, MtbVKOR, has been identified. Here, the Mtb protein Rv2969c is investigated and it is shown that it is the DsbA-like partner protein of MtbVKOR. It is found that it has the characteristic redox features of a DsbA-like protein: a highly acidic catalytic cysteine, a highly oxidizing potential and a destabilizing active-site disulfide bond. Rv2969c also has peptide-oxidizing activity and recognizes peptide segments derived from the periplasmic loops of MtbVKOR. Unlike the archetypal EcDsbA enzyme, Rv2969c has little or no activity in disulfide-reducing and disulfide-isomerase assays. The crystal structure of Rv2969c reveals a canonical DsbA fold comprising a thioredoxin domain with an embedded helical domain. However, Rv2969c diverges considerably from other DsbAs, including having an additional C-terminal helix (H8) that may restrain the mobility of the catalytic helix H1. The enzyme is also characterized by a very shallow hydrophobic binding surface and a negative electrostatic surface potential surrounding the catalytic cysteine. The structure of Rv2969c was also used to model the structure of a paralogous DsbA-like domain of the Ser/Thr protein kinase PknE. Together, these results show that Rv2969c is a DsbA-like protein with unique properties and a limited

  13. Imaging features of musculoskeletal tuberculosis

    International Nuclear Information System (INIS)

    The purpose of this article is to review the imaging characteristics of musculoskeletal tuberculosis. Skeletal tuberculosis represents one-third of all cases of tuberculosis occurring in extrapulmonary sites. Hematogenous spread from a distant focus elsewhere in the body is the cornerstone in the understanding of imaging features of musculoskeletal tuberculosis. The most common presentations are tuberculous spondylitis, arthritis, osteomyelitis, and soft tissue involvement. The diagnostic value of the different imaging techniques, which include conventional radiography, CT, and MR imaging, are emphasized. Whereas conventional radiography is the mainstay in the diagnosis of tuberculous arthritis and osteomyelitis, MR imaging may detect associated bone marrow and soft tissue abnormalities. MR imaging is generally accepted as the imaging modality of choice for diagnosis, demonstration of the extent of the disease of tuberculous spondylitis, and soft tissue tuberculosis. Moreover, it may be very helpful in the differential diagnosis with pyogenic spondylodiscitis, as it may easily demonstrate anterior corner destruction, the relative preservation of the intervertebral disk, multilevel involvement with or without skip lesions, and a large soft tissue abscess, as these are all arguments in favor of a tuberculous spondylitis. On the other hand, CT is still superior in the demonstration of calcifications, which are found in chronic tuberculous abscesses. (orig.)

    Full Text Available Dengue fever is affecting millions of population globally. For the past one decade, we have seen several outbreaks and even causing significant mortality of affected population. We witnessed numerous pattern and multisystem presentation of dengue in this period. The CNS manifestation like encephalitis, polyneuropathy (GB like syndrome and paresthesias were uncommonly reported priorly. Pancreatitis, polyserositis, carditis of varying severity and hepatic failure are the, some of atypical manifestations observed in recent out breaks. So dengue illness can presents with multi system involvement and can account to significant mortality.

    2014-01-01

    Full Text Available Background. Tuberculosis is a chronic disease which may have varied presentations. Though pulmonary tuberculosis is the commonest, extrapulmonary tuberculosis involving skeletal system is often seen. Individuals with poor nourishment and immunological status are especially susceptible for disseminated and multicentric tuberculosis. Case Report. We here present a case of tuberculosis involving multiple anatomical locations in an immune-competent patient which was diagnosed with radiological studies and confirmed with histological examination. Patient was put on multidrug antitubercular therapy and responded well to the treatment with improvement in clinical and radiological picture. Clinical Relevance. This report of a rare case makes us aware of the varied presentations which tuberculosis can present with. It should be kept as a differential diagnosis in patients with cough and fever but not responding to conventional treatment. This is even more important in countries with poor socioeconomic conditions.

    2015-09-01

    Preeclampsia is a pregnancy-related syndrome, which still represents one of the major causes of maternal-fetal mortality and morbidity. Diagnosis can be made difficult due to the complexity of the disorder and its wide spectrum of clinical manifestations. In order to provide an efficient diagnostic tool to the clinician, medical societies regularly rethink the definition criteria. However, there are still clinical presentations of preeclampsia that escape the frame of the definition. The present review will address atypical forms of preeclampsia, such as preeclampsia without proteinuria, normotensive preeclampsia, preeclampsia before 20 weeks of gestation and post-partum preeclampsia.

  19. Tuberculosis in patients with end-stage renal disease

    International Nuclear Information System (INIS)

    The purpose of our study was to describe the clinical and radiological manifestations of tuberculosis in patients with end-stage renal disease. The medical records, chest radiographs, and CT scans of 42 patients with tuberculosis among 871 consecutive patients with end-stage renal disease were reviewed. Patterns of initial chest radiographs were categorized as primary, postprimary, miliary, or atypical, according to the predominant radiologic findings. Chest radiographs and CT scans revealed pulmonary tuberculosis in 28 patients and extrapulmonary tuberculosis in 15. The pattern of chest radiographs indicative of pulmonary tuberculosis was primary in 12 cases, postprimary in 11, miliary in one, demonstrated atypical infiltrates in three, and was normal in one. Tuberculosis involved the extrathoracic lymph nodes in six cases, the peritoneum in four, the spine in three, and the bone marrow in two. The primary pattern, seen in 12 patients, manifested as pleural effusion or segmental consolidation, and in ten of the twelve the former was dominant. The radiological pattern of pulmonary tuberculosis in end-stage renal disease is often primary, and extrapulmonary involvement is frequent

  1. Cavitary pulmonary tuberculosis HIV-related

    International Nuclear Information System (INIS)

    Introduction: It was usually assumed that pulmonary tuberculosis (TB) in HIV-seropositive patients represents reactivation TB, despite the radiographic appearance frequently consistent rather with a recent disease. Hence, these radiographic features were considered 'atypical'. We have hypothesised that the so called 'atypical' radiographic features could be due to a greater proportion of primary TB among these patients, representing the typical appearance of primary radiological pattern. Material and methods: We reviewed chest imaging of 219 HIV+ patients with microbiological proven pulmonary tuberculosis, who were assessed for the presence, number, distribution of cavitations and for associated pulmonary parenchymal abnormalities, adenopathies and pleural effusion, and were classified as a primary or post-primary pattern. Results: The patients with post-primary pattern were 50%, and the rate of cavitation was 63%, not wandering off the general population. Cavities still occurred with similar proportion in groups with CD4 200 cells/mm3. Conclusion: We suggest that HIV-related pulmonary tuberculosis is typical in its radiological appearances, consistent with those of the general population, and this could be confirmed by the most recent molecular epidemiological techniques that allow to definitely classify the tuberculosis episodes as either primary or post-primary disease

  2. Dermatofibroma: Atypical presentations

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Dermatofibroma is a common benign fibrohistiocytic tumor and its diagnosis is easy when it presents classical clinicopathological features. However, a dermatofibroma may show a wide variety of clinicopathological variants and, therefore, the diagnosis may be difficult. The typical dermatofibroma generally occurs as a single or multiple firm reddish-brown nodules. We report here two atypical presentations of dermatofibroma - Atrophic dermatofibroma and keloidal presentation of dermatofibroma. Clinical dermal atrophy is a common phenomenon in dermatofibromas as demonstrated by the dimpling on lateral pressure. However, this feature is exaggerated in the atrophic variant of dermatofibroma. Atrophic dermatofibroma is defined by dermal atrophy of more than 50% of the lesion apart from the usual features of common dermatofibroma. The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

  4. Tuberculosis of the Gallbladder

    OpenAIRE

    2000-01-01

    Analysis of 5 patients with gallbladder tuberculosis who had open cholecystectomy and review of literature have shown that, although still rare it presents as a part of systemic miliary tuberculosis, abdominal tuberculosis, isolated gallbladder tuberculosis and as acalculus cholecystitis in anergic patients. There are no pathognomonic signs, the diagnosis depends on suspicion of tuberculosis, peroperative findings and histological examination.

    Full Text Available Background: Tuberculosis infection is the most common co-infection among Human Immunodeficiency Virus (HIV sero-positives in high tuberculosis prevalence countries. Radiological presentation of pulmonary tuberculosis (PTB is variable in both HIV negative and positive patients. But this variability is more in HIV positive patients. Objective: To study radiological manifestations in patients of pulmonary tuberculosis with HIV. Materials and Methods: In this prospective observational study we studied radiological findings of pulmonary tuberculosis cases having HIV infection in Shree M. P. Shah Medical College & Guru Gobind Sing Hospital, Jamnagar, Gujarat from November 2003 to July 2006. Results: There was a higher involvement of lower lung field (41.86% as compare to upper lung field (23.26% while 34.88% had extensive disease. Cavitary lesions were more frequently observed in extensive diseases (60%. Incidence of mediastinal lymphadenopathy and pleural effusion was equal in upper lung field while in lower lung field; incidence of mediastinal lymphadenopathy was higher as compare to pleural effusion. Conclusion: In HIV positive patients, pulmonary tuberculosis is more likely to present with atypical radiological images. So, in HIV positive patients, we must consider PTB in all atypical radiological presentation for prompt diagnosis and management. Key message: HIV positive patients presenting with lower lung field lesions even without cavitary lesion, possibility of TB should always be considered. [Natl J of Med Res 2012; 2(4.000: 420-422

  6. Did ice-age bovids spread tuberculosis?

    Rothschild, Bruce M.; Martin, Larry D.

    2006-11-01

    Pathognomonic metacarpal undermining is a skeletal pathology that has been associated with Mycobacterium tuberculosis in bovids. Postcranial artiodactyl, perissodactyl, and carnivore skeletons were examined in major university and museum collections of North America and Europe for evidence of this and other pathology potentially attributable to tuberculosis. Among nonproboscidean mammals from pre-Holocene North America, bone lesions indicative of tuberculosis were restricted to immigrant bovids from Eurasia. No bone lesions compatible with diagnosis of tuberculosis were found in large samples of other pre-Holocene (164 Oligocene, 397 Miocene, and 1,041 Plio Pleistocene) North American mammals, including 114 antilocaprids. Given the unchanged frequency of bovid tubercular disease during the Pleistocene, it appears that most did not die from the disease but actually reached an accommodation with it (as did the mastodon) (Rothschild and Laub 2006). Thus, they were sufficiently long-lived to assure greater spread of the disease. The relationships of the proboscidean examples need further study, but present evidence suggests a Holarctic spread of tuberculosis during the Pleistocene, with bovids acting as vectors. While the role of other animals in the transmission of tuberculosis could be considered, the unique accommodation achieved by bovids and mastodons makes them the likely “culprits” in its spread.

    A 40-year-old Mauritanian man consulted for back pain. A computed tomography of the spine showed patchy sclerosis of the fifth and seventh thoracic vertebral bodies with normal neural arch of T5 and sclerosis and hypertrophy of the neural arch of T7, as well as diffuse sclerosis of the T11 vertebral body with a normal neural arch. At MRI, low signal-intensity on T1-weighted images and high signal-intensity on T2-weighted images involved the whole T5 and T7 vertebrae and the vertebral body of T11. Working diagnoses included metastatic disease and lymphoma, and a biopsy of T7 and then T11 was carried out. Both showed pathological findings very suggestive of Paget's disease. Since CT is usually the more specific radiological examination in vertebral Paget's disease, we thought it could be useful to report this atypical CT presentation (patchy sclerosis of the vertebral body without diffuse bone texture changes and isolated involvement of the vertebral body) of vertebral Paget's disease.

    A 14 year old patient with short stature, type I diabetes, and cataracts was referred for evaluation of avascular necrosis of the femoral head. Radiography was suggestive of spondyloepiphyseal dysplasia with decreased bone mineral density for age. Targeted molecular and biochemical testing were normal in this patient. Whole exome sequencing was performed and showed compound heterozygosity for previously reported pathogenic GALNS variants which were diagnostic of mucopolysaccharidosis, type IVA (Morquio A). While this case describes neither a novel condition nor a new mutation, it does illustrate three important points in the diagnosis of patients with atypical forms of MPS IVA. First, that in many instances urine glycosaminoglycan analysis is not sufficient to rule out MPS IVA as a potential diagnosis. Patients in whom biochemical screening is advised should have measurement of leukocyte enzymatic activity. Second, that in patients with radiographic evidence of spondyloepiphyseal dysplasia with additional features or with normal targeted testing, MPS IVA should remain in the differential diagnosis. Third, that whole exome sequencing represents a viable diagnostic platform for evaluation of patients with unknown skeletal or metabolic disease.

  20. Atypical moles: diagnosis and management.

    Perkins, Allen; Duffy, R Lamar

    2015-06-01

    Atypical moles are benign pigmented lesions. Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure. Atypical moles are characterized by size of 6 mm or more at the greatest dimension, color variegation, border irregularity, and pebbled texture. They are associated with an increased risk of melanoma, warranting enhanced surveillance, especially in patients with more than 50 moles and a family history of melanoma. Because an individual lesion is unlikely to display malignant transformation, biopsy of all atypical moles is neither clinically beneficial nor cost-effective. The ABCDE (asymmetry, border irregularity, color unevenness, diameter of 6 mm or more, evolution) mnemonic is a valuable tool for clinicians and patients to identify lesions that could be melanoma. Also, according to the "ugly duckling" concept, benign moles tend to have a similar appearance, whereas an outlier with a different appearance is more likely to be undergoing malignant change. Atypical moles with changes suggestive of malignant melanoma should be biopsied, using an excisional method, if possible.

  1. Recognition and diagnosis of atypical depression.

    Science.gov (United States)

    Thase, Michael E

    2007-01-01

    The term atypical depression dates to the first wave of reports describing differential response to monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). In contrast to more TCA-responsive depressions, patients with so-called atypical symptoms (e.g., hypersomnia, interpersonal sensitivity, leaden paralysis, increased appetite and/or weight, and phobic anxiety) were observed to be more responsive to MAOIs. After several decades of controversy and debate, the phrase "with atypical features" was added as an episode specifier in the DSM-IV in 1994. The 1-year prevalence of the defined atypical depression subtype is approximately 1% to 4%; around 15% to 29% of patients with major depressive disorder have atypical depression. Hardly "atypical" in contemporary contexts, atypical depression also is common in dysthymic bipolar II disorders and is notable for its early age at onset, more chronic course, and high rates of comorbidity with social phobia and panic disorder with agoraphobia. The requirement of preserved mood reactivity is arguably the most controversial of the DSM-IV criteria for atypical depression. When compared with melancholia, the neurobiological profiles of patients with atypical depression are relatively normal. The utility of the atypical depression subtype for differential therapeutics diminished substantially when the TCAs were supplanted as first-line antidepressants by the selective serotonin reuptake inhibitors. Although introduction of safer MAOIs has fostered renewed interest in atypical depression, the validity and importance of the DSM-IV definition of atypical depression for the nosology of affective illness remains an open question.

    Due to an increasing amount of patients on immunosuppressive treatment, the number of tuberculosis (TB) of atypical course and extrapulmonary tuberculosis cases increase. Locomotor system is a place of every fifth case of extrapulmonary TB. Because of lack of characteristic symptoms, as well as rare co-occurrence of active lung lesions in radiological imaging, proper diagnosis is hard to establish. We present a case of patient on immunosuppressive therapy due to myositis, in whom we diagnosed musculoskeletal tuberculosis in form of involvement of tendon sheath and formation of synovial cyst.

    Exercise increases skeletal muscle glucose uptake, but the underlying mechanisms are only partially understood. The atypical protein kinase C (PKC) isoforms λ and ζ (PKC-λ/ζ) have been shown to be necessary for insulin-, AICAR-, and metformin-stimulated glucose uptake in skeletal muscle, but not for treadmill exercise-stimulated muscle glucose uptake. To investigate if PKC-λ/ζ activity is required for contraction-stimulated muscle glucose uptake, we used mice with tibialis anterior muscle-specific overexpression of an empty vector (WT), wild-type PKC-ζ (PKC-ζ(WT)), or an enzymatically inactive T410A-PKC-ζ mutant (PKC-ζ(T410A)). We also studied skeletal muscle-specific PKC-λ knockout (MλKO) mice. Basal glucose uptake was similar between WT, PKC-ζ(WT), and PKC-ζ(T410A) tibialis anterior muscles. In contrast, in situ contraction-stimulated glucose uptake was increased in PKC-ζ(T410A) tibialis anterior muscles compared to WT or PKC-ζ(WT) tibialis anterior muscles. Furthermore, in vitro contraction-stimulated glucose uptake was greater in soleus muscles of MλKO mice than WT controls. Thus, loss of PKC-λ/ζ activity increases contraction-stimulated muscle glucose uptake. These data clearly demonstrate that PKC-λζ activity is not necessary for contraction-stimulated glucose uptake.

    2016-01-01

    When stress fractures started to show up in the femurs of elderly ladies, it was soon evident that bisphosphonate use lay behind, and the absolute risk increase due to bisphosphonate use was reasonably well estimated already in 2008. Thereafter followed a period of confusion: the term atypical fracture was introduced, with a definition so vague that the true stress fractures tended to disappear in a cloud of ambiguity. This cast doubt on the association with bisphosphonates. The association was then re-established by large epidemiological studies based on radiographic adjudication. Atypical fractures are largely caused by bisphosphonates. With a correct indication, bisphosphonates prevent many more fractures than they cause, at least during the first years of use. With an incorrect indication they are likely to cause more harm than good. PMID:26768286

    Abstract Background: Spinal tuberculosis is the most common form of skeletal tuberculosis. However, there were limited data to evaluate the trend of spinal tuberculosis research. This study aims to investigate the trend of spinal tuberculosis research and compare the contribution of research from different countries and authors. Methods: Spinal tuberculosis-related publications from 1994 to 2015 were retrieved from the Web of Science database. Excel 2013, GraphPad Prism 5, and VOSviewer software were used to analyze the search results for number of publications, cited frequency, H-index, and country contributions. Results: A total of 1558 papers were identified and were cited 16,152 times as of January 25, 2016. The United States accounted for 15.1% of the articles, 22.3% of the citations, and the highest H-index (33). China ranked third in total number of articles, fifth in citation frequency (815), and ranked seventh in H-index (13). The journal Spine (IF 2.297) had the highest number of publications. The author Jain A.K. has published the most papers in this field (20). The article titled “Tuberculosis of the spine: Controversies and a new challenge” was the most popular article and cited a total of 1138 times. The keyword “disease” was mentioned the most for 118 times and the word “bone fusion” was the latest hotspot by 2015. Conclusion: Literature growth in spinal tuberculosis is slowly expanding. Although publications from China are increasing, the quality of the articles still requires improvements. Meanwhile, the United States continues to be the largest contributor in the field of spinal tuberculosis. According to our bibliometric study, bone fusion may be an emerging topic within spinal tuberculosis research and is something that should be closely observed. PMID:27661044

    We investigate Turing's notion of an A-type artificial neural network. We study a refinement of Turing's original idea, motivated by work of Teuscher, Bull, Preen and Copeland. Our A-types can process binary data by accepting and outputting sequences of binary vectors; hence we can associate a function to an A-type, and we say the A-type {\\em represents} the function. There are two modes of data processing: clamped and sequential. We describe an evolutionary algorithm, involving graph-theoretic manipulations of A-types, which searches for A-types representing a given function. The algorithm uses both mutation and crossover operators. We implemented the algorithm and applied it to three benchmark tasks. We found that the algorithm performed much better than a random search. For two out of the three tasks, the algorithm with crossover performed better than a mutation-only version.

  11. Tuberculosis and nutrition

    2009-01-01

    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.

    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 ({approx} 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)

Materials and Methods: A retrospective chart review of patients of extragonadal germ cell tumors between 2000 and 2010 was carried out. Results: Fifteen children aged 7 days to 15 years (median, 1.5 years were included. Three had an antenatal diagnosis (one sacrococcygeal, one retrobulbar, one retroperitoneal tumor and were operated in the neonatal period. The locations were distributed between the retrobulbar area (1, anterior neck-thyroid gland (1, mediastinum (4, abdominothoracic extending through the esophageal hiatus (1, retroperitoneal (4 and sacrococcygeal (4. On histological examination, five harbored immature elements while two were malignant; the latter children received postexcision adjuvant chemotherapy. There was no mortality. At a median follow-up of 4.5 years (6 months to 8 years, 14/15 have had an event-free survival. One immature mediastinal teratoma that recurred locally 7.5 years after the initial operation was excised and adjuvant chemotherapy instituted. Conclusions: Extragonadal GCTs in children are uncommon and occasionally present with atypical clinical, radiological and histological features resulting in diagnostic and therapeutic dilemmas.

    2013-09-01

    Full Text Available Introduction: Vestibular schwannoma (also known as acoustic neuroma is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its symptoms are varied, but what stands out most is a unilateral sensorineural hearing loss, with a low index of speech recognition. Objective: Describe an atypical manifestation of vestibular schwannoma. Case Report: The 46-year-old woman had vertigo and binaural hearing loss and fullness, with ear, nose, and throat examination suggestive of cochlear injury. After 6 months, the patient developed worsening of symptoms and onset of right unilateral tinnitus. In further exams the signs of cochlear damage remained, except for the vestibular test (hyporeflexia. Magnetic resonance imaging showed an expansive lesion in the right cerebellopontine angle. Discussion: This report warns about the atypical manifestations of vestibular schwannoma, which must always be remembered in investigating and diagnosing hearing loss.

  19. Problems in distinguishing spinal tuberculosis from neoplasia on MRI

    International Nuclear Information System (INIS)

    We reviewed MRI studies of 60 patients presenting with extradural compressive myeloradiculopathy secondary to vertebral disease to assess the imaging features which may help in differentiating tuberculous from neoplastic disease. Spin-echo T1-, proton density- and T2-weighted images were available for all patients and fast low-angle shot images with a low flip angle for 21 patients. Contrast-enhanced images were available for 28 patients. There were 41 patients with tuberculosis and 19 patients with neoplastic disease (metastases 11, lymphoma 6, plasmacytoma 1, and giant cell tumour 1). Discovertebral disease with or without involvement of the posterior arch was a feature not only of tuberculous spondylitis (30 patients) but also of metastases (6). The remaining 11 patients with tuberculosis had ''atypical'' involvement (vertebral body with or without posterior arch in 8 and posterior arch alone in 3) described as typical of neoplasms. This ''typical'' involvement was seen in metastases (5), lymphoma (6) and the 2 primary bone tumours. The presence of an abscess helped in differentiating tuberculosis from neoplasia in 22 of the 41 patients with tuberculosis and was absent in all with neoplasms. The presence of bone fragments in 16 patients (8 with and 8 without an abscess) was found to be specific for tuberculosis. In the absence of an abscess or bone fragments, image-guided biopsy is essential to establish the diagnosis. (orig.). With 9 figs., 2 tabs

  20. Tuberculosis among older adults – time to take notice

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Knowledge that older people are vulnerable to develop tuberculosis is rarely considered in developing country settings. According to 2010 Global Burden of Disease estimates, the majority of tuberculosis-related deaths occurred among people older than 50; most in those aged 65 and above. Older people also contribute a large proportion of Disability-Adjusted Life Years (DALYs; 51% of tuberculosis DALYs occurred in patients aged 50 years and older in East Asia. Tuberculosis age distributions in Africa have been severely skewed by the human immunodeficiency virus (HIV epidemic, but emerging data suggest increasing disease burdens among older people. Older adults are more likely to develop extra-pulmonary and atypical forms of disease that are often harder to diagnose than conventional sputum smear-positive pulmonary tuberculosis. Their care is complicated by more frequent drug-related adverse events and increased co-morbidity, which may prove difficult to manage in regions where health resources are already constrained. Health systems will have to confront the challenge of an ageing global population and the integrated services required to address their health needs.

    Pharyngeal tuberculosis is a rare extrapulmonary manifestation. In Argentina, the number of cases of tuberculosis reported in children under 19 years in 2012 was 1752. Only 12.15% had extrapulmonary manifestation. A case of a 17 year old girl with pharyngeal tuberculosis is reported. The patient presented intermittent fever and swallowing pain for 6 months, without response to conventional antibiotic treatment. Chest X-ray showedbilateral micronodular infiltrate, so hospitalization was decided to study and treat. The sputum examination for acid-fast resistant bacilli was positive and treatment with four antituberculous drugs was started, with good evolution and disappearance of symptoms. Diagnostic confirmation with the isolation of Mycobacterium tuberculosis in sputum culture was obtained. The main symptoms of pharyngeal tuberculosis are sore throat and difficulty in swallowing of long evolution. It is important to consider tuberculosis as differential diagnosis in patients with chronic pharyngitis unresponsive to conventional treatment. PMID:26172025

  2. Pictorial essay: Orbital tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis of the orbit is rare, even in places where tuberculosis is endemic. The disease may involve soft tissue, the lacrimal gland, or the periosteum or bones of the orbital wall. Intracranial extension, in the form of extradural abscess, and infratemporal fossa extension has been described. This pictorial essay illustrates the imaging findings of nine histopathologically confirmed cases of orbital tuberculosis. All these patients responded to antituberculous treatment

  3. Tuberculosis treatment among smear positive tuberculosis patients

    International Nuclear Information System (INIS)

    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)

  4. Radiological profile of pulmonary tuberculosis in HIV: concerning 171 observations in Kinshasa

    International Nuclear Information System (INIS)

    This prospective descriptive study was conducted in Depistage center of the Tuberculosis treatment of Kabinda during a period of three months, had as objectives to study the radiological profile of pulmonary tuberculosis in HIV and HIV- patients, then to compare the frequency of different radiological abnormalities between the two groups to determine some characteristics of co-infection HIV/TP+. Among 171 patients with contagious pulmonary tuberculosis, 50 patients had positive serology for HIV, a prevalence of 29,2%. The intrathoracic lymph nodes, localized lesions only in the lower field were more observed in HIV, as well as pleurisy and the absence of radiological abnormality. The only one case of miliary was HIV positive. By contrast, excavations and localized lesions in the upper field were predominant in HIV-. Atypical radiological manifestations of pulmonary tuberculosis were more common in patients with HIV infection.

    The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV) and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001), showed a higher frequency of weight loss >10 kilos (p tuberculosis (p = 0.001). Treatment failure was more common in those who were HIV positive (p extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

    2014-01-01

    Autophagy as an immune mechanism controls inflammation and acts as a cell-autonomous defense against intracellular microbes including Mycobacterium tuberculosis. An equally significant role of autophagy is its anti-inflammatory and tissue-sparing function. This combination of antimicrobial and anti-inflammatory actions prevents active disease in animal models. In human populations, genetic links between autophagy, inflammatory bowel disease, and susceptibility to tuberculosis provide further support to these combined roles of autophagy. The autophagic control of M. tuberculosis and prevention of progressive disease provide novel insights into physiological and immune control of tuberculosis. It also offers host-based therapeutic opportunities because autophagy can be pharmacologically modulated. PMID:25167980

    2012-01-01

    AIS hypothesis has the right to recognition, if it explains the transition of "healthy" vertebra column into status of "scoliotic" one. AIS is the most investigated disease in the history of orthopedics, but up the present time there is no clear explanation of some its phenomena: vertebra column mono-form deformation along with its poly etiology character, interrelation of its origin and development and child's growth process etc. The key for authors' view at AIS was scoliosis with non-standard (concave side) rotation. On the bases of its' multifunctional instrumental investigation results (Rtg, EMG, EEG, optical topography, hormonal and neuropeptides trials, thermo-vision methods and other) in comparison with typical AIS was worked out the new hypothesis, part of it is suggested for discussion. In the work under observation is the sequence of appearance of typical and atypical scoliosis symptomatology beginning from the preclinical stage. PMID:22744477

    Merchant, Suleman; Bharati, Alpa; Merchant, Neesha

    2013-01-01

    This article reviews the computed tomography and magnetic resonance imaging (MRI) features of renal tuberculosis (TB), including TB in transplant recipients and immunocompromised patients. Multi detector computed tomography (MDCT) forms the mainstay of cross-sectional imaging in renal TB. It can easily identify calcification, renal scars, mass lesions, and urothelial thickening. The combination of uneven caliectasis, with urothelial thickening and lack of pelvic dilatation, can also be demonstrated on MDCT. MRI is a sensitive modality for demonstration of features of renal TB, including tissue edema, asymmetric perinephric fat stranding, and thickening of Gerota's fascia, all of which may be clues to focal pyelonephritis of tuberculous origin. Diffusion-weighted MR imaging with apparent diffusion coefficient (ADC) values may help in differentiating hydronephrosis from pyonephrosis. ADC values also have the potential to serve as a sensitive non-invasive biomarker of renal fibrosis. Immunocompromised patients are at increased risk of renal TB. In transplant patients, renal TB, including tuberculous interstitial nephritis, is an important cause of graft dysfunction. Renal TB in patients with HIV more often shows greater parenchymal affection, with poorly formed granulomas and relatively less frequent findings of caseation and stenosis. Atypical mycobacterial infections are also more common in immunocompromised patients. PMID:23986619

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

    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.

    2012-01-01

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    2011-10-01

    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of central nervous system classically characterized by acute, severe episodes of optic neuritis and longitudinally extensive transverse myelitis, usually with a relapsing course. The identification of an autoantibody exclusively detected in NMO patients against aquaporin-4 (AQP-4 has allowed identification of cases beyond the classical phenotype. Brain lesions, once thought as infrequent, can be observed in NMO patients, but lesions have different characteristics from the ones seen in multiple sclerosis. Additionally, some AQP-4 antibody positive patients may present with a variety of symptoms not being restricted to optic neuritis and acute myelitis during the first attack or in a relapse. Examples are not limited to, but may include patients only with brain and/or brainstem lesions, narcolepsy with hypothalamic lesions or patients with intractable hiccups, nausea and vomiting. The prompt identification of NMO patients with atypical presentations may benefit these patients with institution of early treatment to reduce disability and prevent further attacks.

    Atypical neuropathic facial pain is a syndrome of intractable and unremitting facial pain that is secondary to nociceptive signaling in the trigeminal system. These syndromes are often recalcitrant to pharmacotherapy and other common interventions, including microvascular decompression and percutaneous procedures. Herein, the authors present two other viable approaches (nucleus caudalis dorsal root entry zone lesioning and motor cortex stimulation), their indications, and finally a possible treatment algorithm to consider when assessing patients with atypical facial pain.

    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

    2009-08-01

    The past research of the radiologic manifestations of pulmonary tuberculosis in Japan was based on morphological pathology of the untreated patient autopsy. I would like to show the chest CT scan of tuberculosis diseases with caseous granuloma at its exudative reaction, proliferative reaction, productive reaction, cirrhotic reaction until self cure. This progress reflects the normal cell mediated immunological responses. Also I would like to show the cavitation of granuloma, which results from liquefaction of caseous materials during the course and results in the formation of the source of infection. And finally I would like to show the morphological differences of acinous lesion, acino-nodular lesion and caseous lobular pneumonia. These differences reflect the amount of bacilli disseminated in the peripheral parts under the lobules. In this study, I do not show old age cases and HIV positive cases, who do not form typical granuloma due to the decreased cell mediated immnunity and whose X ray findings are atypical.

    2014-12-01

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

    Full Text Available Abstract Background Extrapulmonary manifestations of tuberculosis have become increasingly important in the era of HIV/AIDS. Case presentation We describe a case of tuberculosis (TB dactylitis in a patient with AIDS who originated from the Ivory Coast. The diagnosis was established by direct visualization of acid-fast bacilli on joint fluid and bone biopsy of the proximal phalanx. Imaging of the chest revealed multiple bilateral nodules. Confirmation of the diagnosis was made by isolation of Mycobacterium tuberculosis from sputum and bone cultures. Conclusion Tuberculosis should be considered in patients with unusual soft tissue or skeletal lesions, especially when an immunosuppressive condition is present. Ziehl-Neelsen staining and culture of tissue obtained via surgical biopsy offer the most direct approach to diagnosis.

  4. Evolution of Mycobacterium tuberculosis.

    Behr, Marcel A

    2013-01-01

    Genomic studies have provided a refined understanding of the genetic diversity within the Mycobacterium genus, and more specifically within Mycobacterium tuberculosis. These results have informed a new perspective on the macro- and micro-evolution of the tubercle bacillus. In the first step, a M. kansasii-like opportunistic pathogen acquired new genes, through horizontal gene transfer, that enabled it to better exploit an intracellular niche and ultimately evolve into a professional pathogen. In the second step, different subspecies and strains of the M. tuberculosis complex emerged through mutation and deletion of unnecessary DNA. Understanding the differences between M. tuberculosis and related less pathogenic mycobacteria is expected to reveal key bacterial virulence mechanisms and provide opportunities to understand host resistance to mycobacterial infection. Understanding differences within the M. tuberculosis complex and the evolutionary forces shaping these differences is important for investigating the basis of its success as both a symbiont and a pathogen.

    Full Text Available Tuberculosis can cause infertility when it infects the genital tract (e.g., endometritis. A 31-year-old woman (origin: Algeria was referred to our academic gynecological institute for unexplained primary infertility. The patient presented with no complaint. Hysteroscopy showed a 10 mm sized endometrial polyp. The polyp was removed. Pathology showed lymphocytic and plasmacytic chronic inflammatory modification, granulomatous modification, and gigantocellular modification,which lead to the diagnosis of tuberculosis. No acid fast organism was seen on Ziehl-Neelsen staining. A chest thorax X-ray revealed no sign of pulmonary tuberculosis. The patient underwent antituberculosis therapy during one year. Posttreatment hysteroscopy revealed no abnormality. This is the first reported case of endometrial tuberculosis diagnosed following removal of a polyp with classical benign appearance.

  10. Correlation of immunologic status with high-resolution CT and distributions of pulmonary tuberculosis

    International Nuclear Information System (INIS)

    Purpose: To investigate the correlation of cluster of differentiation (CD)4 lymphocyte counts with high-resolution CT (HRCT) findings and distribution of pulmonary tuberculosis. Material and Methods: Thirty-seven bacteriologically proven pulmonary tuberculosis, clinically non-AIDS, patients underwent HRCT and CD4 lymphocyte counts in peripheral blood cells were obtained within 3 days after the CT examinations. Patients were categorized into four groups according to CD4 lymphocyte counts (A >800; B 800-500; C 500-200; D <200). HRCT findings analyzed were as follows: typical, atypical, and mixed findings of post-primary tuberculosis, common, uncommon, and mixed distribution, and number of lobes involved. Results: CD4 lymphocyte counts correlated with the degree of the mixture of atypical CT findings (=0.565, p<0.001) and the degree of the mixture of uncommon distribution (=0.431, p<0.01). Number of involved lobes showed no statistically significant correlation (=0.209, p=0.21). Conclusion: In patients with low CD4 levels, atypical HRCT findings co-exist with typical findings, and uncommon sites are involved in addition to common sites

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

    2003-01-01

    Objective To characterize the differences between clinical manifestations in immunocompromised patients (ICPs) and non-immunocompromised patients (non-ICPs) with tuberculosis.Methods Underlying diseases, clinical presentations, misdiagnosis, treatment and prognosis, etc, were analyzed retrospectively in 115 tuberculosis patients, including 39 ICPs and 76 non-ICPs.Results Compared with non-ICPs, the individuals who were ICP had more expectoration (64.1% vs 35.5%), pulmonary moist rale (41.0% vs 9.2%), miliary pulmonary tuberculosis (30.8% vs 2.6%), pleural effusion (48.7% vs 25.0%) and lymphadenopathy (18.0% vs 4.0 %). ICPs had less lung cavity (15.4% vs 22.4%) and pleural thickening (15.4% vs 23.7%) compared to non-ICPs. Pulmonary tuberculosis in ICPs was prone to be misdiagnosed as pneumonia (23.1% vs 6.6%). Pulmonary tuberculosis was found in the apicoposterior segment (SI+SII) in more cases in non-ICPs (21.7%, 10/46) than ICPs (10.3%, 3/29). The diagnostic value of tuberculin skin test and adenosine deaminase in pleural effusions was limited in ICPs. ICPs had significantly poorer prognoses than non-ICPs.Conclusion The clinical manifestations of ICPs with tuberculosis are atypical, misdiagnosis often occurs, resulting in a worse prognosis.

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

    Circular and apparently trans-spliced RNAs have recently been reported as abundant types of transcripts in mammalian transcriptome data. Both types of non-colinear RNAs are also abundant in RNA-seq of different tissue from both the African and the Indonesian coelacanth. We observe more than 8,000 lincRNAs with normal gene structure and several thousands of circularized and trans-spliced products, showing that such atypical RNAs form a substantial contribution to the transcriptome. Surprisingly, the majority of the circularizing and trans-connecting splice junctions are unique to atypical forms, that is, are not used in normal isoforms.

  19. Imaging of Esophageal Tuberculosis

    International Nuclear Information System (INIS)

    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

    2003-11-01

    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

    The question of pre-neolithic tuberculosis is still open in paleopathological perspective. One of the major interests is to explore what type of infection could have existed around the early stage of animal domestication. Paleopathological lesions evoking skeletal TB were observed on five human skeletons coming from two PPNB sites in Syria, which belongs to the geographical cradle of agriculture. These sites represent respectively pre-domestication phase (Dja'de el Mughara, Northern Syria, 8800-8300 BCE cal.) and early domestication phase (Tell Aswad, Southern Syria, 8200-7600 BCE cal.). MicroCT scan analyses were performed on two specimens (one per site) and revealed microscopic changes in favor of TB infection. Detection of lipid biomarkers is positive for two specimens (one per site). Initial molecular analysis further indicates the presence of TB in one individual from Dja'de. Interestingly, no morphological evidence of TB was observed on animal remains of wild and newly domesticated species, discovered in these sites. These observations strongly suggest the presence of human tuberculosis before domestication and at its early stages.

  3. Imaging features of extraaxial musculoskeletal tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis (TB) continues to be a public health problem in both developing and industrialized countries. TB can involve pulmonary as well as extrapulmonary sites. The musculoskeletal system is involved in 1–3% of patients with tuberculosis. Although musculoskeletal TB has become uncommon in the Western world, it remains a huge problem in Asia, Africa, and many developing countries. Tuberculous spondylitis is the most common form of musculoskeletal TB and accounts for approximately 50% of cases. Extraspinal musculoskeletal TB shows a predilection for large joints (hip and knee) and para-articular areas; isolated soft tissue TB is extremely rare. Early diagnosis and prompt treatment are mandatory to prevent serious destruction of joints and skeletal deformity. However, due to the nonspecific and often indolent clinical presentation, the diagnosis may be delayed. Radiological assessment is often the first step in the diagnostic workup of patients with musculoskeletal TB and further investigations are decided by the findings on radiography. Both the radiologist and the clinician should be aware of the possibility of this diagnosis. In this manuscript we review the imaging features of extraspinal bone, joint, and soft tissue TB

    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

    Atypical pressure ulcers (APU) are distinguished from common pressure ulcers (PU) with both unusual location and different aetiology. The occurrence and attempts to characterise APU remain unrecognised. The purpose of this cohort study was to analyse the occurrence of atypical location and the circumstances of the causation, and draw attention to the prevention and treatment by a multidisciplinary team. The cohort study spanned three and a half years totalling 174 patients. The unit incorporates two weekly combined staff meetings. One concentrates on wound assessment with treatment decisions made by the physician and nurse, and the other, a multidisciplinary team reviewing all patients and coordinating treatment. The main finding of this study identified APU occurrence rate of 21% within acquired PU over a three and a half year period. Severe spasticity constituted the largest group in this study and the most difficult to cure wounds, located in medial aspects of knees, elbows and palms. Medical devices caused the second largest occurrence of atypical wounds, located in the nape of the neck, penis and nostrils. Bony deformities were the third recognisable atypical wound group located in shoulder blades and upper spine. These three categories are definable and time observable. APU are important to be recognisable, and can be healed as well as being prevented. The prominent role of the multidisciplinary team is primary in identification, prevention and treatment.

    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.

  18. Skeletal surveys in multiple myeloma

    International Nuclear Information System (INIS)

    Thirty-three patients with multiple myeloma were studied with serial skeletal surveys, serum immunoglobulin levels, and postabsorptive urinary hydroxyproline (Spot-HYPRO) determinations. Twenty receiving chemotherapy were also followed with skeletal surveys in order to evaluate bone response to treatment. A close association was found between skeletal findings and changes in immunoglubulin levels with positive correlation in 71% of the patients. A similar association was found between skeletal disease and Spot-HYPRO level changes in 65%. Five of 12 patients (42%) with partial or complete clinical response to chemotherapy, demonstrated improvement in the appearance of skeletal lesions. Positive correlation between the roentgenographic changes and clinical markers of myeloma as well as therapeutic response, indicates that skeletal surveys are useful and effective in monitoring patients with multiple myeloma.

    Full Text Available Background : Fight against human immunodeficiency virus (HIV is incomplete without addressing problems associated with difficult diagnosis of tuberculosis in HIV-Tuberculosis coinfected patients. Chest X-ray is a primary tool to evaluate tuberculosis in HIV. Aim: To assess and compare various radiological patterns of pulmonary tuberculosis in HIV patients and compare these patterns in relation to CD4 counts. Materials and Methods : Prospective cohort study was conducted in a tertiary hospital in South India from September 2009 to July 2011 with 200 HIV positive patients. WHO guidelines were used for diagnosis of HIV and tuberculosis. Results : 27% of the patients had sputum positive pulmonary tuberculosis, with higher incidence (33% among CD4 less than 200 as compared to CD4 more than 200 (14%. Infiltration (39% followed by consolidation (30%, cavity (11%, and lymphadenopathy (9% seen with CD4 less than 200. Infiltration (37.5% followed by cavity (25% and miliary (25% with CD4 above 200. Bilateral (68.5% and mid and lower zones or all zone involvement more commonly seen. Conclusion : In patients with CD4 lower than 200 noncavitory infiltration and consolidation predominated. Involvement of lungs was atypical; diffuse or mid and lower zone involvement than classical upper lobe involvement. A high index of suspicion is necessary for the accurate and timely diagnosis of tuberculosis in HIV positive patients.

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

    Full Text Available Immune response to Mycobacterium tuberculosis, the causal agent of tuberculosis, is critical for protection. For many decades, consistent to classical biochemistry, most studies regarding immunity to the tubercle bacilli focused mainly on protein structures. But the atypical, highly impermeable and waxy coat of mycobacteria captured the interest of structural biologists very early, allowing the description of amazing molecules, such as previously unknown carbohydrates or fatty acids of astonishing lengths. From their discovery, cell wall components were identified as important structural pillars, but also as molecular motifs able to alter the human immune response. Recently, as new developments have emerged, classical conceptions of mycobacterial immune modulators have been giving place to unexpected discoveries that, at the turn of the last century, completely changed our perception of immunity vis-à-vis fat compounds. In this paper, current knowledge about chemical and ultrastructural features of mycobacterial cell-wall is overviewed, with an emphasis on the relationships between cell-wall nonpeptide molecules and immune response. Remarks regarding the potential of these molecules for the development of new tools against tuberculosis are finally discussed.

    Smoking is a leading cause of preventable death and disability. Smoking has long been identified as a risk factor for osteoporosis, with data showing that older smokers have decreased bone mineral density and increased fracture risk compared to nonsmokers, particularly at the hip. The increase in fracture risk in smokers is out of proportion to the effects on bone density, indicating deficits in bone quality. Advanced imaging techniques have demonstrated microarchitectural deterioration in smokers, particularly in the trabecular compartment. The mechanisms by which smoking affects skeletal health remain unclear, although multiple pathways have been proposed. Smoking cessation may at least partially reverse the adverse effects of smoking on the skeleton.

    The joy of diagnostic radiology is derived in great measure in its neverending variety including the unveiling of new diagnostic entities and new information concerning known disease processes. This year is no exception in the fascinating documentation of skeletal disease. In the study of disorders of the joints, CT investigation of the temporomandibular joint and arthotomography of the shoulder are gaining in popularity. New observations concerning cyst-like osseous lesions in lupus erthematosis, destructive joint lesions in renal osteodystrophy, and intra- and periarticular calcifications secondary to steroid injections have come forward. Articles discussing interesting observations concerning chondrosarcoma are included as well as one that describes the demonstration of fluid levels in aneurysmal bone cysts by CT. Ossification in soft tissues following resection of giant cell tumors as evidence of residual neoplasm is an important new sign. Marrow transplantation for treatment of mucopolysaccharidosis represents a new therapeutic breakthrough. Some of the skeletal manifestions of hypomagnesemia, 13-cis-retinoic acid, and aluminum are elucidated in this year's articles on metabolic disease. Further studies of methods of measuring bone density are also included

    We present a case of an atypical recurrent meningioma of the sacrum with pulmonary metastasis in a 31-year-old man. He presented with deep-seated buttock pain and urinary hesitancy for 3 months. MRI revealed a lesion occupying the central and left side of the sacral canal at the S1-S2 level. Surgical excision of the lesion via a posterior approach was undertaken, and the patient became symptom-free post-operatively. Histology confirmed atypical meningioma. Eight months later he re-presented with similar symptoms, and MRI confirmed local recurrence. The patient underwent left hemisacrectomy. Six months later he again presented with low back pain and MRI confirmed a second local recurrence. A CT scan of the chest showed multiple lung metastases. The patient died of a severe chest infection 18 months later. (orig.)

    Abstract Introduction: Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland tumor that is found on the fingers, toes, and the digits. To date, <100 cases have been reported in the literature. Apart from 1 case reported in the thigh, all of them were on digital or nondigital acral skin. Case presentation: A 67-year-old Caucasian woman was admitted to the hospital due to a mass on the scalp. This lesion was present for almost a year. It was a semimobile cyctic mass that elevated the scalp. There was no change in the skin color. Its dimensions were 1.5 × 1 × 0.6 cm. The laboratory, clinic, and radiologic findings (head x-ray) of the patient were normal. It was evaluated as a benign lesion such as lipoma or epidermal cyst by a surgeon due to a small semimobile mass and no erosion of the skull. It was excised by a local surgery excision. The result of the pathologic examination was aggressive papillary adenocarcinoma. This diagnosis is synonymous with ADPA. Conclusion: In our case, localization was scalp. This localization is the first for this tumor in the literature. In addition, another atypical localization of this tumor (ADPA) is thigh in the literature. This case was presented due to both the rare and atypical localizations. That is why, in our opinion, revision of “digital” term in ADPA is necessary due to seem in atypical localizations like thigh and scalp. PMID:27428196

    Summary Diabetes mellitus was identified as a risk factor for developing tuberculosis (TB) infection, and relapse after therapy. The risk of acquiring TB is described as comparable to that of HIV population. The fact that diabetics are 3× times more prone to develop pulmonary TB than nondiabetics cannot be overlooked. With DM recognized as global epidemic, and TB affecting one-third of the world population, physicians must remain vigilant. We present a 45-year-old woman born in Dominican Republic (DR), with 10-year history of T2DM treated with metformin, arrived to our Urgency Room complaining of dry cough for the past 3months. Interview unveiled unintentional 15lbs weight loss, night sweats, occasional unquantified fever, and general malaise but denied bloody sputum. She traveled to DR 2years before, with no known ill exposure. Physical examination showed a thin body habitus, otherwise well appearing woman with stable vital signs, presenting solely right middle lung field ronchi. LDH, ESR, hsCRP and Hg A1C were elevated. Imaging revealed a right middle lobe cavitation. Sputum for AFB disclosed active pulmonary TB. Our case portrays that the consideration of TB as differential diagnosis in diabetics should be exercised with the same strength, as it is undertaken during the evaluation of HIV patients with lung cavitation. Inability to recognize TB will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. Learning points Diabetes mellitus should be considered an important risk factor for the reactivation of pulmonary tuberculosis. High clinical suspicious should be taken into consideration as radiological findings for pulmonary tuberculosis in patients with diabetes mellitus may be atypical, involving middle and lower lobes. Inability to recognize pulmonary tuberculosis will endanger the patient, hospital dwellers and staff, and perpetuate this global public health menace. PMID:27482384

We thought that transpupillary thermotherapy (TTT utilizing a lower temperature than that of conventional laser photocoagulation might minimize permanent retinal and choroidal damage. Studies suggest that undesirable effects on vision due to TTT are minimal even if it is applied to foveal and/or parafoveal lesions when TTT requires a larger irradiation spot. The aim of this study was to evaluate the efficacy of TTT in the management of atypical CSC.Methods: We defined atypical CSC as bullous retinal detachment with diffuse or several leakages, severe leakage with fibrin formation under serous retinal detachment, or leakage within a pigment epithelium detachment. Eight consecutive patients with atypical CSC underwent visual acuity testing, ophthalmic examination, color photography, fluorescein angiography, and optical coherence tomography to evaluate the results of transpupillary thermotherapy. Retreatment of atypical CSC was based on ophthalmic examination, optical coherence tomography, and fluorescein angiography. TTT was performed on the leaking spots shown in fluorescein angiography, with a power of 50–250 mW, spot size of 500–1200 µm, and exposure time of 13–60 seconds to minimize retinal damage.Results: In five of eight affected eyes, serous detachments completely resolved within 1 month after the initial TTT. One eye had persistent subretinal fluid and required a second TTT treatment. Two eyes showed no resolution of CSC and were treated by conventional photocoagulation. Initial best-corrected visual acuity (BCVA ranged from 20/600 to 20/20 (mean, 20/40; median, 20/30. Final BCVA

    Full Text Available Introduction: Afflictions of shoulder by tuberculosis is rare and when it occurs its more commonly a dry lesion (caries sicca. Wet lesions in shoulder are rare and we report this case for the rarity of its occurrence. Case Report: A 55yrs old female patient presented with a painful swelling with restriction of movements of the right shoulder since six months. Patient had taken various treatments without any relief; there was no history of trauma, weight loss, recent infection in the past or any history of tuberculosis in family or contact with tubercular patient. Right shoulder revealed restricted movements with no local rise in temperature. Tenderness was present over anterior and posterior aspect of the right shoulder diffusely. External rotation and abduction movements were restricted while adduction and flexion were not restricted. Power of the muscles was unaffected with no neurological deficit. Antero-posterior and axial X-rays of the right shoulder showed no bony involvement however, ultrasonography showed lipoma. Serological investigations showed a markedly raised erythrocyte sedimentation rate (73mm / hr and a positive C-reactive protein. Surgical excision of the mass revealed rice bodies. DNA PCR was positive for tuberculosis and patient was started on anti-tubercular treatment( Category I for six months. Conclusion: Any patient coming with the complaints of long standing painful restriction of the movements of the shoulder associated with or without complaints swelling, shall be evaluated to rule out skeletal tuberculosis along with other differential diagnosis of periarthritis of shoulder and adhesive capsulitis. Most of the patients with skeletal tuberculosis may not necessarily present with the constitutional symptoms of fever, weight loss, etc and also because of the widespread prevalence of the organism in India.

  6. Extensively drug-resistant tuberculosis.

    Jassal, Mandeep; Bishai, William R

    2009-01-01

    Extensively drug-resistant (XDR) tuberculosis is defined as disease caused by Mycobacterium tuberculosis with resistance to at least isoniazid and rifampicin, any fluoroquinolone, and at least one of three injectable second-line drugs (amikacin, capreomycin, or kanamycin). The definition has applicable clinical value and has allowed for more uniform surveillance in varied international settings. Recent surveillance data have indicated that the prevalence of tuberculosis drug resistance has risen to the highest rate ever recorded. The gold standard for drug-susceptibility testing has been the agar proportion method; however, this technique requires several weeks for results to be determined. More sensitive and specific diagnostic tests are still unavailable in resource-limited settings. Clinical manifestations, although variable in different settings and among different strains, have in general shown that XDR tuberculosis is associated with greater morbidity and mortality than non-XDR tuberculosis. The treatment of XDR tuberculosis should include agents to which the organism is susceptible, and should continue for a minimum of 18-24 months. However, treatment continues to be limited in tuberculosis-endemic countries largely because of weaknesses in national tuberculosis health-care models. The ultimate strategy to control drug-resistant tuberculosis is one that implements a comprehensive approach incorporating innovation from the political, social, economic, and scientific realms.

    Since the discovery of the Roentgen ray a precise and accurate assessment of bone mineral content has been a challenge to many investigators. A number of methods have been developed but no one satisfied. Considering its technical possibilities computed tomography is very promising in determination of bone mineral content (BMC). The new modality enables BMC estimations in the axial skeletal trabecular bone. CT densitometry can be performed on a normal commercially available third generation whole body CT scanner. No dedicated device in a special clinical set-up is necessary. In this study 106 patients, most of them clinically suspected of osteoporosis, were examined. The new method CT densitometry has been evaluated. The results have been correlated to alternative BMC determination methods. (Auth.)

    Skeletal dysplasia is a disorder of skeletal development characterized by abnormality in shape, length, a number and mineral density of the bone. Skeletal dysplasia is often associated with manifestation of other organs such as lung, brain and sensory systems. Skeletal dysplasias or dysostosis are classified with more than 400 different names. Enchondral bone formation is a coordinated event of chondrocyte proliferation, differentiation and exchange of terminally maturated chondrocyte with bone. Impaired enchondral bone formation will lead to skeletal dysplasia, especially associated with short long bones. Appropriate bone volume and mineral density are achieved by balance of bone formation and bone resorption and mineralization. The gene encoding fibroblast growth factor receptor 3 is responsible for achondroplasia, representative skeletal dysplasia with short stature. The treatment with growth hormone is approved for achondroplasia in Japan. Osteogenesis imperfecta is characterized by low bone mineral density and fragile bone. Data on the beneficial effect of bisphosphonate for osteogenesis imperfecta are accumulating. Osteopetrosis has high bone mineral density, but sometimes show bone fragility. In Japan as well as other countries, pediatrician treat larger numbers of patients with skeletal dysplasia with short stature and fragile bones compared to 20 years ago.

    Full Text Available Though commonly encountered, extrapulmonary tuberculosis (TB can sometimes present with variable clinical picture intricating the diagnosis. The nonspecific symptoms include pyrexia of unknown origin, hepatosplenomegaly, lymphadenopathy, meningitis, and, rarely, variety of hematological abnormalities, namely, anemia, pancytopenia, and leukemoid reaction. When it presents with bone marrow (BM involvement, prognosis is usually poor. We, hereby, report a case of unusual TB presentation with a 4 month history of fever associated with fatigability, and diarrhea. During the hospital stay and follow up, the patient showed a spectrum of interesting hematological findings, including pancytopenia on peripheral smear, caseating granulomas consistent with TB on bone marrow examination. The patient showed a good clinical as well as hematological response to anti-tuberculosis treatment. This paper highlights the significance of a hematological picture in the final confirmation of TB, which may otherwise be passed off as nutritional or other unrelated causes.

    Aim: Atypical lymphocytes usually described as lymphocytes with altered shape, increased DNA amount, and larger size. For analysis of cause of genesis and source of atypical lymphocytes during African swine fever virus (ASFV) infection, bone marrow, peripheral blood, and in vitro model were investigated. Materials and Methods: Atypical lymphocytes under the influence of ASFV were studied for morphologic, cytophotometric, and membrane surface marker characteristics and were used in vivo and in vitro models. Results: This study indicated the increased size, high metabolic activity, and the presence of additional DNA amount in atypical lymphocytes caused by ASFV infection. Furthermore, in atypical lymphocytes, nuclear-cytoplasmic ratio usually decreased, compared to normal lymphocytes. In morphology, they looking like lymphocytes transformed into blasts by exposure to mitogens or antigens in vitro. They vary in morphologic detail, but most of them are CD2 positive. Conclusions: Our data suggest that atypical lymphocytes may represent an unusual and specific cellular response to ASFV infection. PMID:27536044

    International Nuclear Information System (INIS)

    Despite the fact that joint tuberculosis is one of the most common forms of extrapulmonary tuberculosis, it is a disease entity that is very rare in Poland (less than 100 cases a year in the last 10 years). The symptoms are non-specific, and thus the disease is rarely taken into account in preliminary differential diagnosis. A 68-year-old female patient was admitted to the Internal Diseases Clinic due to oedema and pain of the right shoulder joint. The pain has been increasing for about 8 months. Physical examination revealed increased circumference and elevated temperature of the right shoulder joint. Limb function was retained. The full range of radiological and laboratory diagnostic examinations was performed, including the biopsy of the affected tissue which revealed the presence of Mycobacterium tuberculosis in the bacterial culture. Clinical improvement was obtained after introduction of TB drugs. Radiological diagnostic methods (X-ray, CT scans, MRI scans) provide high precision monitoring of articular lesions. However, the decisive diagnosis requires additional laboratory tests as well as histopathological and bacteriological assays

    A 9-year-old girl with neurofibromatosis type 1 (NF1) presented with a massive atypical meningioma and calvarial defect. Skull radiographs and cranial CT showed an extensive lytic bone lesion at the vertex. MRI demonstrated a large mass invading the calvarium and sagittal sinus. The histopathological and immunohistochemical diagnosis of the resected mass was atypical meningioma. To our knowledge, this is the first case of NF1 associated with atypical meningioma and massive calvarial defect in a child. (orig.)

    Full Text Available Endemic skeletal fluorosis is widely prevalent in India and is a major public health problem. The first ever report of endemic skeletal fluorosis and neurological manifestation was from Prakasam district in Andhra Pradesh in the year 1937. Epidemiological and experimental studies in the endemic areas suggest the role of temperate climate, hard physical labor, nutritional status, presence of abnormal concentrations of trace elements like strontium, uranium, silica in water supplies, high fluoride levels in foods and presence of kidney disease in the development of skeletal fluorosis. Neurological complications of endemic skeletal fluorosis, namely radiculopathy, myelopathy or both are mechanical in nature and till date the evidence for direct neurotoxicity of fluoride is lacking. Prevention of the disease should be the aim, knowing the pathogenesis of fluorosis. Surgery has a limited role in alleviating the neurological disability and should be tailored to the individual based on the imaging findings.

  2. Hematological Side Effects of Atypical Antipsychotic Drugs

    Full Text Available Atypical antipsychotics cause less frequently extrapyramidal system symptoms, neuroleptic malignant syndrome and hyperprolactinemia than typical antipsychotics. However hematological side effects such as leukopenia and neutropenia could occur during treatment with atypical antipsychotics. These side effects could lead to life threatening situations and the mortality rate due to drug related agranulocytosis is about 5-10%. There are several hypothesis describing the mechanisms underlying drug induced leukopenia and/or neutropenia such as direct toxic effects of these drugs upon the bone marrow or myeloid precursors, immunologic destruction of the granulocytes or supression of the granulopoiesis. Clozapine is the antipsychotic agent which has been most commonly associated with agranulocytosis. A nitrenium ion which is formed by the bioactivation of clozapine is thought to have an important role in the pathophysiogy of this adverse effect. Aside from clozapine, there are several case reports reporting an association between olanzapine, quetiapine, risperidone, ziprasidone, aripiprazole and leukopenia. We did not find any study or case report presenting amisulpride or sulpride related hematological side effects in our literature search. Patients who had hematological side effects during their previous antipsychotic drug treatments and who had lower baseline blood leukocyte counts, have higher risk to develop leukopenia or neutropenia during their current antipsychotic treatment. Once leukopenia and neutropenia develops, drugs thought to be responsible for this side effect should be discontinued or dosages should be lowered. In some cases iniatition of lithium or G-CSF (granulocyte colony-stimulating factor therapy may be helpful in normalizing blood cell counts. Clinicans should avoid any combination of drugs known to cause hematological side effects. Besides during antipsychotic treatment, infection symptoms such as fever, cough, sore throat or

    Full Text Available Obsessive-compulsive disorder (OCD is one of the most prevalent psychiatric disorders in children and adolescents. The phenomenology of OCD in children and adolescent is strikingly similar to that of adults. But at times, the presentation of OCD may be so atypical or unusual in children and adolescents that may lead to misdiagnosis or delay in diagnosis. We report a case of 10-year-old child who was initially misdiagnosed with schizophrenia, and treated with antipsychotic for 2 months. But once the core symptoms were recognized as obsessions and compulsions and appropriately treated in the line of OCD, the symptoms resolved significantly.

  12. TUBERCULOSIS AND LUNG CANCER.

    2016-01-01

    The occurrence of pulmonary tuberculosis (PTB) and lung cancer as comorbidities has been extensively discussed in many studies. In the past, it was well known that lung cancer is a specific epidemiological successor of PTB and that lung cancer often develops in scars caused by PTB. In recent years, the relevance of the two diseases has drawn attention in terms of the close epidemiological connection and chronic inflammation-associated carcinogenesis. In Japanese case series studies, most lung cancer patients with tuberculous sequelae received supportive care alone in the past, but more recently, the use of aggressive lung cancer treatment is increasing. Many studies on PTB and lung cancer as comorbidities have revealed that active PTB is noted in 2-5% of lung cancer cases, whereas lung cancer is noted in 1-2% of active PTB cases. In such instances of comorbidity, many active PTB cases showed Type II (non-extensively cavitary disease) and Spread 2-3 (intermediate-extensive diseases) on chest X-rays, but standard anti-tuberculosis treatment easily eradicates negative conversion of sputum culture for M. tuberculosis; lung cancer cases were often stage III- IV and squamous cell carcinoma predominant, and the administration of aggressive treatment for lung cancer is increasing. The major clinical problems associated with PTB and lung cancer as comorbidities include delay in diagnosis (doctor's delay) and therapeutic limitations. The former involves two factors of radiographic interpretation: the principles of parsimony (Occam's razor) and visual search; the latter involves three factors of lung cancer treatment: infectivity of M.tuberculosis, anatomical limitation due to lung damage by tuberculosis, and drug-drug interactions between rifampicin and anti-cancer drugs, especially molecularly targeted drugs. The comorbidity of these two diseases is an important health-related issue in Japan. In the treatment of PTB, the possibility of concurrent lung cancer should be kept

    2014-01-01

    The normal human chromosome complement consists of 46 chromosomes comprising 22 morphologically different pairs of autosomes and one pair of sex chromosomes. Variations in either chromosome number and/or structure frequently result in significant mental impairment, and/or a variety of other clinical problems, among them, altered bone mass and strength. Chromosomal syndromes associated with specific chromosomal abnormalities are classified as either numerical or structural and may involve more than one chromosome. Aneuploidy refers to the presence of an extra copy of a specific chromosome, or trisomy, as seen in Down’s syndrome (trisomy 21), or the absence of a single chromosome, or monosomy, as seen in Turner syndrome (a single X chromosome in females: 45, X). Aneuploidies have diverse phenotypic consequences, ranging from severe mental retardation and developmental abnormalities to increased susceptibility to various neoplasms and premature death. In fact, trisomy 21 is the prototypical aneuploidy in humans, is the most common genetic abnormality associated with longevity and is one of the most widespread genetic causes of intellectual disability. In this review, the impact of trisomy 21 on the bone mass, architecture, skeletal health and quality of life of people with Down syndrome will be discussed. PMID:24980541

    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

    Tuberculosis peritonitis is a rare manifestation of extrapulmonary tuberculosis. The results of gallium-67 scintigraphy of three patients with tuberculosis peritonitis were reviewed to assess its usefulness in the diagnosis of this condition. Tuberculosis peritonitis was associated with diffuse or focal abdominal localization and decreased hepatic accumulation of gallium-67. These gallium-67 scan features of tuberculosis peritonitis may help to optimize the diagnosis and management of this disease. PMID:10435380

    Orofacial pain' most commonly occurs due to dental causes like caries, gingivitis or periodontitis. Other common causes of 'orofacial pain' are sinusitis, temporomandibular joint(TMJ) dysfunction, otitis externa, tension headache and migraine. In some patients, the etiology of 'orofacial pain' remains undetected despite optimal evaluation. A few patients in the practice of clinical dentistry presents with dental pain without any identifiable dental etiology. Such patients are classified under the category of 'atypical odontalgia'. 'Atypical odontalgia' is reported to be prevalent in 2.1% of the individuals. 'Atypical orofacial pain' and 'atypical odontalgia' can result from the neurological diseases like multiple sclerosis, trigeminal neuralgia and herpes infection. Trigeminal neuralgia has been frequently documented as a cause of 'atypical orofacial pain' and 'atypical odontalgia'. There are a few isolated case reports of acute pontine stroke resulting in 'atypical orofacial pain' and 'atypical odontalgia'. However, pontine stroke as a cause of atypical odontalgia is limited to only a few cases, hence prevalence is not established. This case is one, where a patient presented with acute onset atypical dental pain with no identifiable dental etiology, further diagnosed as an acute pontine infarct on neuroimaging. A 40 years old male presented with acute onset, diffuse teeth pain on right side. Dental examination was normal. Magnetic resonance imaging(MRI) of the brain had an acute infarct in right pons near the trigeminal root entry zone(REZ). Pontine infarct presenting with dental pain as a manifestation of trigeminal neuropathy, has rarely been reported previously. This stresses on the importance of neuroradiology in evaluation of atypical cases of dental pain. PMID:26464604

    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.

    Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.

  9. Chest radiology in HIV-positive patients with tuberculosis - analysis of 104 cases

    International Nuclear Information System (INIS)

    Radiological examinations from 104 patients HIV-positive with tuberculosis were revised at HUGG/Uni-Rio, during the period from June/86 to June/89. From these, 91.4% were male patients, the predominant risk group was homosexual. Among the women, the most affected group was the intravenous drug consumer. The general age group mostly presented was the one from 20 to 39 years. The main tuberculosis confirmation came from the BAAR research in the sputum (57.6%); the necropsy contributed with 13.5% of the patients. The extrathoracic manifestations occurred in 27% of the cases. The most common radiological patterns were interstitial infiltrate 71.2%, bilateral in 48% of the cases, in the alveolar patterns 63.5%, mostly upper lobes, frequently they were simultaneous. Other important findings were: mediastinal lymphatic involvement, pleural effusion, cavity and X-ray without particularities with pulmonary tuberculosis. A comparison study was performed based on literature data and it was observed atypical patterns for the secondary tuberculosis. (author)

    Full Text Available The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001, showed a higher frequency of weight loss >10 kilos (p <0.001, had a higher rate of non-reaction result to the tuberculin skin test (p <0.001, a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001 and negative sputum culture for Mycobacterium tuberculosis (p = 0.001. Treatment failure was more common in those who were HIV positive (p <0.000. No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407. Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

    Several changes have been observed in the epidemiology, clinical manifestations, diagnostic modalities and treatment of tuberculosis. Emergence of HIV epidemic and drug resistance have posed significant challenges. With increase in the number of diseased adults and spread of HIV infection, the infection rates in children are likely to increase. It is estimated that in developing countries, the annual risk of tuberculosis infection in children is 2.5%. Nearly 8-20% of the deaths caused by tuberculosis occur in children. Extra pulmonary tuberculosis has increased over last two decades. HIV infected children are at an increased risk of tuberculosis, particularly disseminated disease. In last two decades, drug resistant tuberculosis has increased gradually with emergence of MDR and XDR-TB. The rate of drug resistance to any drug varied from 20% to 80% in different geographic regions. Significant changes have occurred in TB diagnostics. Various diagnostic techniques such as fluorescence LED microscopy, improved culture techniques, antigen detection, nucleic acid amplification, line probe assays and IGRAs have been developed and evaluated to improve diagnosis of childhood tuberculosis. Serodiagnosis is an attractive investigation but till date none of the tests have desirable sensitivity and specificity. Tests based on nucleic acid amplification are a promising advance but relatively less experience in children, need for technical expertise and high cost are limiting factors for their use in children with tuberculosis.

    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.

    The link between heart and skeletal muscle disorders is based on similar molecular, anatomical and clinical features, which are shared by the 'primary' cardiomyopathies and 'primary' neuromuscular disorders. There are, however, some peculiarities that are typical of cardiac and skeletal muscle disorders. Skeletal muscle weakness presenting at any age may indicate a primary neuromuscular disorder (associated with creatine kinase elevation as in dystrophinopathies), a mitochondrial disease (particularly if encephalopathy, ocular myopathy, retinitis, neurosensorineural deafness, lactic acidosis are present), a storage disorder (progressive exercise intolerance, cognitive impairment and retinitis pigmentosa, as in Danon disease), or metabolic disorders (hypoglycaemia, metabolic acidosis, hyperammonaemia or other specific biochemical abnormalities). In such patients, skeletal muscle weakness usually precedes the cardiomyopathy and dominates the clinical picture. Nevertheless, skeletal involvement may be subtle, and the first clinical manifestation of a neuromuscular disorder may be the occurrence of heart failure, conduction disorders or ventricular arrhythmias due to cardiomyopathy. ECG and echocardiogram, and eventually, a more detailed cardiovascular evaluation may be required to identify early cardiac involvement. Paediatric and adult cardiologists should be proactive in screening for neuromuscular and related disorders to enable diagnosis in probands and evaluation of families with a focus on the identification of those at risk of cardiac arrhythmia and emboli who may require specific prophylactic treatments, for example, pacemaker, implantable cardioverter-defibrillator and anticoagulation.

    Neurobiological abnormalities underlying atypical depression have previously been suggested. The purpose of this study was to explore differences at functional brain imaging between depressed patients with and without atypical features and healthy controls. Twenty-three out-patients with chronic depressive disorder recruited from a service for patients with audiological symptoms were investigated. Eleven fulfilled the DSM-IV criteria for atypical depression (mood reactivity and at least two of the following: weight gain, hypersomnia, leaden paralysis and interpersonal rejection sensitivity). Twenty-three healthy subjects served as controls. Voxel-based analysis was applied to explore differences in {sup 99m}Tc-HMPAO uptake between groups. Patients in the atypical group had a higher prevalence of bilateral hearing impairment and higher depression and somatic distress ratings at the time of SPECT. Significantly higher tracer uptake was found bilaterally in the atypical group as compared with the non-atypicals in the sensorimotor (Brodmann areas, BA1-3) and premotor cortex in the superior frontal gyri (BA6), in the middle frontal cortex (BA8), in the parietal associative cortex (BA5, BA7) and in the inferior parietal lobule (BA40). Significantly lower tracer distribution was found in the right hemisphere in the non-atypicals compared with the controls in BA6, BA8, BA44, BA45 and BA46 in the frontal cortex, in the orbito-frontal cortex (BA11, BA47), in the postcentral parietal cortex (BA2) and in the multimodal association parietal cortex (BA40). The differences found between atypical and non-atypical depressed patients suggest different neurobiological substrates in these patient groups. The putative links with the clinical features of atypical depression are discussed. These findings encourage the use of functional neuroimaging in psychiatric disorders. (orig.)

    Hitherto it has not been usual to talk in the German language about the therapy-oriented concept of two forms of the progress of atypical depression (Type A and Type V). The characteristic symptom of Type A is angst, together with phobias, physical complaints, etc. In Type V there are vegetative symptoms, often towards evening (Hypersomnia, difficulty in getting to sleep, increased appetite, increased weight, increased libido), accompanied by hysterical extrovert personality traits, and of intermittent occurrence. These clinical pictures are amenable to psychopharmalogical therapy. In conformity with the assumption of "somatic accommodation" treatment with antidepressives is recommended in the case neurotic depression, too, at least in the initial stages of treatment.

    In a consecutive series of 1,925 head injuries, 283 patients (14.7%), could not be classified, neither in the group of simple head injuries without cerebral symptoms, nor in the group of typical concussions characterized by immediate amnesia or observed coma. We have prefered the rather neutral term of atypical early posttraumatic syndromes. In this group, apart from neurovegetative manifestations, partial disturbances of consciousness and perception, we have also classified delayed disturbances of consciousness. Special attention has been given to migraineous phenomena and to a syndrome, characteristic for children, described by Mealey. This is an intermediate group important from a medico-legal point of view because certain transient cerebral manifestations risk to be mistaken for psychological reactions. On the other hand symptoms probably of psychic origin were discussed. PMID:4469864

    Metastatic pulmonary calcification is a condition of calcium deposition in the normal pulmonary parenchyma, and this is secondary to abnormal calcium metabolism without any prior soft tissue damage. The predisposing factors for this condition include chronic renal failure, hypercalcemia and increased tissue alkalinity. The most common radiologic manifestation consists of poorly defined nodular opacities in the upper lung zone. These opacities reflect the deposition of calcium salts in the pulmonary interstitium. We present here a case of metastatic pulmonary calcification in a patient who recovered from pneumonia with sepsis and whose high-resolution CT (HRCT) images demonstrated localized parenchymal airspace calcification that was limited to the bilateral lower lobes. These lower lobes had been involved with pneumonic consolidation without calcification, as seen on the previous CT scan. In summary, we report here on an atypical presentation of metastatic pulmonary calcification that showed dense airspace consolidation localized to the bilateral lower lobes in a patient with primary hyperparathyroidism and pneumonia.

    Cornelia de Lange Syndrome (CdLS) (also called Bushy Syndrome or Amsterdam dwarfism), is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    A lack of reliable statistics makes tuberculosis (TB) trends in developing countries difficult to estimate. Nonetheless, the World Health Organization and the International Union against Tuberculosis and Lung Disease estimated in 1990 that one-third of the world's population was infected with the tubercle bacillus and that there were 7-8 million new cases of TB annually. 95% of the new cases occurred in the developing world, with more than 5 million in Asia and the Western Pacific and more than 1 million in sub-Saharan Africa. Almost 80% of TB cases in developing countries occur among those under age 50 years. The global annual mortality was estimated at 2.5 million, with 98% of deaths occurring in developing countries. Worldwide, TB is believed to be responsible for 25% of avoidable deaths in young adults. There has been no significant decline in the average annual risk of infection in most developing countries due to incomplete coverage by control programs and inadequate cure rates. The interaction of HIV infection with TB is another factor which contributes to the deteriorating TB situation in many developing countries. Countries with a high population growth rate and little decline in the annual risk of infection should expect either a static or increasing level of TB disease. Immigration from developing countries, HIV infection, poverty, unemployment, homelessness, overcrowding, and population aging contribute to the spread of TB in developed countries. Drug resistance thwarts the control of TB worldwide. PMID:8972116

  1. Cellular therapy in Tuberculosis

    Full Text Available Cellular therapy now offer promise of potential adjunct therapeutic options for treatment of drug-resistant tuberculosis (TB. We review here the role of Mesenchymal stromal cells, (MSCs, as well as other immune effector cells in the therapy of infectious diseases with a focus on TB. MSCs represent a population of tissue-resident non-hematopoietic adult progenitor cells which home into injured tissues increase the proliferative potential of broncho-alveolar stem cells and restore lung epithelium. MSCs have been shown to be immune-modulatory and anti-inflammatory mediated via cell-cell contacts as well as soluble factors. We discuss the functional profile of MSCs and their potential use for adjunct cellular therapy of multi-drug resistant TB, with the aim of limiting tissue damage, and to convert unproductive inflammatory responses into effective anti-pathogen directed immune responses. Adjunct cellular therapy could potentially offer salvage therapy options for patients with drug-resistant TB, increase clinically relevant anti-M.tuberculosis directed immune responses and possibly shorten the duration of anti-TB therapy.

  2. Simultaneous immunization against tuberculosis.

    Directory of Open Access Journals (Sweden)

    Elma Z Tchilian

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

Studies have demonstrated that PSP can present clinically as an atypical dementing syndrome dominated by a progressive apraxia of speech (AOS and aphasia. Aim: We aimed to investigate the clinical presentation of PSP, using a comprehensive multidimensional evaluation, and the disease response to various pharmacological treatments. Methods: A 72-year-old right-handed male, with 17 years education, who first presented with aphasia, AOS, depression, apathy, and postural instability at 69 years; a complete neuropsychological evaluation, tapping the different cognitive domains, was performed. Results: Testing revealed a moderate global cognitive deficit (Mini-Mental State Examination test score =20, low memory test scores (story recall, Rey’s 15-word Immediate and Delayed Recall, and poor phonemic and semantic fluency. The patient’s language was characterized by AOS, with slow speech rate, prolonged intervals between syllables and words, decreased articulatory accuracy, sound distortions, and anomia. Behavioral changes, such as depression, anxiety, apathy, and irritability, were reported. The neurological examination revealed supranuclear vertical gaze palsy, poor face miming, and a mild balance deficit. Magnetic resonance imaging showed only widespread cortical atrophy. Single photon emission computed tomography demonstrated left > right frontotemporal cortical abnormalities. After 6 months, a further neuropsychological assessment showed a progression in cognitive deficits, with additional attention deficits. The patient reported frequent falls, but the neurological deficits remained unchanged. Neuroimaging tests showed the same brain involvement. Conclusion: Our case highlights the heterogeneity of the clinical features in

    Anorexia nervosa (AN) is a psychiatric illness with profound medical consequences. Among the many adverse physical sequelae of AN, bone health is impacted by starvation and can be permanently impaired over the course of the illness. In this review of skeletal complications associated with eating disorders, we discuss the epidemiology, neuroendocrine changes, adolescent vs. adult skeletal considerations, orthopedic concerns, assessment of bone health, and treatment options for individuals with AN. The focus of the review is the skeletal sequelae associated with anorexia nervosa, but we also briefly consider other eating disorders that may afflict adolescents and young adults. The review presents updates to the field of bone health in AN, and also suggests knowledge gaps and areas for future investigation. PMID:26166318

    International Nuclear Information System (INIS)

    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)

Lesions are frequently reported on hands and lower limbs. It is an occupational hazard in people who handle tuberculous tissues during work, example: Veterinarians and mortuary at tenders, farmers, butchers, anatomy at tenders (anatomist’s warts. Auto inoculation by sputum in a pulmonary tuberculosis pati ent can cause the disease. Clinical features are variable, but verrucosity always forms. Lesions are usually single indurated, verrucous plaque with serpigenous edge which may show some scar at centre with keloidal changes and are seen at trauma prone site s. Histopathology shows psedoepitheliomatous hyperplasia with infiltration of plasma cells and sometimes with caseating granuloma. Tissues rarely show positivity to bacilli on staining. Treatment of the disease is by anti TB therapy which will completely resolve the lesion.

    Tuberculosis is an airborne infectious disease treated with combination therapeutic regimens. Adherence to long-term antituberculosis therapy is crucial for maintaining adequate blood drug level. The emergence and spread of drug-resistant Mycobacterium tuberculosis strains are mainly favored by the inadequate medical management of the patients. The therapeutic approach for drug-resistant tuberculosis is cumbersome, because of the poor, expensive, less-effective, and toxic alternatives to the first-line drugs. New antituberculosis drugs (bedaquiline and delamanid) have been recently approved by the health authorities, but they cannot represent the definitive solution to the clinical management of drug-resistant tuberculosis forms, particularly in intermediate economy settings where the prevalence of drug resistance is high (China, India, and former Soviet Union countries). New research and development activities are urgently needed. Public health policies are required to preserve the new and old therapeutic options. PMID:25573773

    This study compares the effects of atypical and conventional antipsychotic medications on treatment continuation and outcomes in a first admission sample of patients with schizophrenia treated in usual practice settings. In a sample of 189 participants with a research diagnosis of DSM-IV schizophrenia drawn from the Suffolk County Mental Health Project, we compared the effects of atypical and conventional agents on change of medication, medication gaps, and rehospitalization. For these analyses we used the method of survival analysis for recurrent events, in which the episodes of treatment rather than individual subjects are the units of analysis. In addition, we compared improvement in positive and negative symptoms from intake to 24- or 48-month followups for subjects who stayed on one type of medication or changed to atypicals from conventional antipsychotics. Atypical agents were associated with lower risk of medication change, medication gaps, and rehospitalization. Both conventional and atypical agents were associated with improvement of positive symptoms at followup, but only subjects on atypical agents at followup experienced a significant improvement in negative symptoms. We conclude that in usual practice settings, as in randomized clinical trials, atypical agents are associated with improved treatment continuation and outcomes.

    Full Text Available Abstract Aims The aim of this study was to find out the characteristic morphology of malignant atypical cells which were missed on routine cytology of urine. Materials and methods In this retrospective study, we examined detailed cytomorphology of 18 cases of atypical urinary cytology which were missed on routine examination and were further proved on histopathology as transitional cell carcinoma (TCC of bladder. The cytological features of these cases were compared with 10 cases of benign urine samples. Results There were 11 cases of high grade TCC and 7 cases of low grade TCC on histopathology of the atypical urine samples. Necrosis in the background and necrosed papillae were mostly seen in malignant atypical cells. The comet cells and cells with India ink nuclei (single cells with deep black structure-less nuclei were only observed in malignant atypical cells. The most consistent features in malignant atypical cells were: i high nuclear and cytoplasmic (N/C ratio ii nuclear pleomorphism iii nuclear margin irregularity iv hyperchromasia and v chromatin abnormalities Conclusion The present study emphasizes that nuclear features such as high N/C ratio, hyperchromasia and chromatin abnormalities are particularly useful for assessing the malignant atypical cells. Other cytological features such as comet cells and cells with India ink nuclei are also helpful for diagnosis but have limited value because they are less frequently seen.

    The chemokine system is a fundamental component of cancer-related inflammation involved in all stages of cancer development. It controls not only leukocyte infiltration in primary tumors but also angiogenesis, cancer cell proliferation, and migration to metastatic sites. Atypical chemokine receptors are a new, emerging class of regulators of the chemokine system. They control chemokine bioavailability by scavenging, transporting, or storing chemokines. They can also regulate the activity of canonical chemokine receptors with which they share the ligands by forming heterodimers or by modulating their expression levels or signaling activity. Here, we summarize recent results about the role of these receptors (atypical chemokine receptor 1/Duffy antigen receptor for chemokine, atypical chemokine receptor 2/D6, atypical chemokine receptor 3/CXC-chemokine receptor 7, and atypical chemokine receptor 4/CC-chemokine receptor-like 1) on the tumorigenesis process, indicating that their effects are strictly dependent on the cell type on which they are expressed and on their coexpression with other chemokine receptors. Indeed, atypical chemokine receptors inhibit tumor growth and progression through their activity as negative regulators of chemokine bioavailability, whereas, on the contrary, they can promote tumorigenesis when they regulate the signaling of other chemokine receptors, such as CXC-chemokine receptor 4. Thus, atypical chemokine receptors are key components of the regulatory network of inflammation and immunity in cancer and may have a major effect on anti-inflammatory and immunotherapeutic strategies.

    Current dogma suggests aerobic exercise training has minimal effect on skeletal muscle size. We and others have demonstrated that aerobic exercise acutely and chronically alters protein metabolism and induces skeletal muscle hypertrophy. These findings promote an antithesis to the status quo by providing novel perspective on skeletal muscle mass regulation and insight into exercise-countermeasures for populations prone to muscle loss.

  17. Detection and molecular characterization of 9,000-year-old Mycobacterium tuberculosis from a Neolithic settlement in the Eastern Mediterranean.

    Directory of Open Access Journals (Sweden)

    Israel Hershkovitz

    Full Text Available BACKGROUND: Mycobacterium tuberculosis is the principal etiologic agent of human tuberculosis. It has no environmental reservoir and is believed to have co-evolved with its host over millennia. This is supported by skeletal evidence of the disease in early humans, and inferred from M. tuberculosis genomic analysis. Direct examination of ancient human remains for M. tuberculosis biomarkers should aid our understanding of the nature of prehistoric tuberculosis and the host/pathogen relationship. METHODOLOGY/PRINCIPAL FINDINGS: We used conventional PCR to examine bone samples with typical tuberculosis lesions from a woman and infant, who were buried together in the now submerged site of Atlit-Yam in the Eastern Mediterranean, dating from 9,250-8,160 years ago. Rigorous precautions were taken to prevent contamination, and independent centers were used to confirm authenticity of findings. DNA from five M tuberculosis genetic loci was detected and had characteristics consistent with extant genetic lineages. High performance liquid chromatography was used as an independent method of verification and it directly detected mycolic acid lipid biomarkers, specific for the M. tuberculosis complex. CONCLUSIONS/SIGNIFICANCE: Human tuberculosis was confirmed by morphological and molecular methods in a population living in one of the first villages with evidence of agriculture and animal domestication. The widespread use of animals was not a source of infection but may have supported a denser human population that facilitated transmission of the tubercle bacillus. The similarity of the M. tuberculosis genetic signature with those of today gives support to the theory of a long-term co-existence of host and pathogen.

    Full Text Available Psoriasis is a chronic, relapsing and remitting inflammatory skin and joint disease that has a prevalence of 2-3% in the world’s population, whereas of 1–2% in Europe. The traditional concept of psoriasis as the “healthy people’s” disease has been recently revised because of ever-increasing reports of associations with various pathological conditions (hypertension, Crohn’s disease, type II diabetes mellitus, obesity, dyslipidemia, metabolic syndrome, infectious conditions. Particularly, advances in psoriasis therapies have introduced biologic agents. All the tumor necrosis factor-alpha inhibitors are associated with an increased risk of developing active disease in patients with latent tuberculosis infection, because of TNF-α key role against Mycobacterium tuberculosis. For this reason, exclusion of active tuberculosis and treatment of latent tuberculosis infection are clinical imperatives prior to starting this therapy. Moreover active surveillance for a history of untreated or partially treated tuberculosis or latent form has already been shown to be effective in reducing the number of incident tuberculosis cases.

    Skeletal muscle relaxants are widely used in treating musculoskeletal conditions. However, evidence of their effectiveness consists mainly of studies with poor methodologic design. In addition, these drugs have not been proven to be superior to acetaminophen or nonsteroidal anti-inflammatory drugs for low back pain. Systematic reviews and meta-analyses support using skeletal muscle relaxants for short-term relief of acute low back pain when nonsteroidal anti-inflammatory drugs or acetaminophen are not effective or tolerated. Comparison studies have not shown one skeletal muscle relaxant to be superior to another. Cyclobenzaprine is the most heavily studied and has been shown to be effective for various musculoskeletal conditions. The sedative properties of tizanidine and cyclobenzaprine may benefit patients with insomnia caused by severe muscle spasms. Methocarbamol and metaxalone are less sedating, although effectiveness evidence is limited. Adverse effects, particularly dizziness and drowsiness, are consistently reported with all skeletal muscle relaxants. The potential adverse effects should be communicated clearly to the patient. Because of limited comparable effectiveness data, choice of agent should be based on side-effect profile, patient preference, abuse potential, and possible drug interactions. PMID:18711953

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

    The intersecting HIV and Tuberculosis epidemics in countries with a high disease burden of both infections pose many challenges and opportunities. For patients infected with HIV in high TB burden countries, the diagnosis of TB, ARV drug choices in treating HIV-TB coinfected patients, when to initiate ARV treatment in relation to TB treatment, managing immune reconstitution, minimising risk of getting infected with TB and/or managing recurrent TB, minimizing airborne transmission, and infection control are key issues. In addition, given the disproportionate burden of HIV in women in these settings, sexual reproductive health issues and particular high mortality rates associated with TB during pregnancy are important. The scaleup and resource allocation to access antiretroviral treatment in these high HIV and TB settings provide a unique opportunity to strengthen both services and impact positively in meeting Millennium Development Goal 6.

But, as we enter the 21th century, TB continue be a global public health problem and if there is no improvement in TB control, the number of new TB cases is projected to rise to 11 million by 2020. Problems faced include inability to deliver / assure chemotherapy, deficient case finding, inadequate vaccine, rising level of drug resistance, failure to employ preventive chemotherapy and migration, HIV epidemics and nosocomial transmission. As far as recent advances in TB diagnostics, there is a need to find a tool for identification of latent infection, detection of diseases in migrant and other high risk populations, replace or facilitate AFB microscopy, improve the diagnosis of AFB smear-negative cases, and simple tools for determining drugs susceptibility. New diagnostic technologies includes nucleic acid probes, amplification tests, high performances liquid chromatography (HPLC, gas / liquid chromatography (GLC, and automated system for radiometric and non radiometric detection and molecular fingerprinting approach. In the coming years new drugs are needed, especially to shorten the duration of TB treatment or otherwise simplify its completion, improve the treatment of latent TB infection and to be eliminate. MDR-TB. There are some problems in pursue tuberculosis research because of the high investment required to bring a product to market and lack of likely commercial returns. Some new drugs and molecules with promising antimycobacterial activity include Fluoroquinolone, Oxazolidinones, Nitroimidazole, Thiolactomycine, Nitroimidazopyran and Isocitrate lyase inhibitor. To deliver good case finding and treatment, effective TB control program should be implemented in the country, as well as globally.

    Objective. Unusual manifestations are occasionally encountered in Langerhans cell histiocytosis and may be a source of confusion. The objective of this study was to determine the frequency of occurrence of the unusual manifestations in our case material. Design and patients. Thirty-four children, average age 4.4 years (range 3 months to 16 years) with 262 skeletal lesions of biopsy-proven Langerhans cell histiocytosis (LCH) were retrospectively reviewed to determine the frequency of occurrence of unusual manifestations defined either as an atypical location of a skeletal lesion or an atypical radiographic appearance of the lesion. Results. Twenty-four unusual lesions were found in this retrospective review. Among these were epiphyseal lesions, transphyseal lesions, extracranial `button` sequestra, posterior vertebral arch lesions, dural extension of vertebral lesions, and fluid-fluid levels. The finding of fluid-fluid levels has not previously been described in the radiologic literature. Involvement of unusual sites included clavicles and small bones of the hands and feet. Conclusions. Radiographic, computed tomographic, and magnetic resonance imaging of LCH yield a variety of unusual manifestations. Recognition of these varied appearances of LCH may prevent confusion of such appearances with other pathologic processes. When the unusual manifestation occurs as the initial finding of the disease, LCH should be included in the differential diagnosis. (orig.) With 7 figs., 10 refs.

    The treatment of HIV infection has changed dramatically in recent years as a result of the development of new drugs which allows a variety of multitherapy combinations more adapted to patients' needs and thereby improving compliance. Efavirenz is a non-nucleoside reverse transcriptase inhibitor. In addition to a potent antiretroviral activity, efavirenz is an easy-to-take drug with once-daily dosing and is usually well tolerated. Efavirenz, however, may induce psychic alterations which are variable and atypical in both their clinical presentation and severity. As early as the first days of treatment, efavirenz may provoke surprising phenomena such as nightmares, vivid dreams, hallucinations or illusions, and twilight states. Depersonalization and derealization episodes, personality alterations, stream of thought troubles and unusual thought contents, atypical depression and cognitive disorders have also been observed. These phenomena may occur either early or later on treatment. The prevalence of severe psychic disorders is less than 5%, but they are often responsible for harmful treatment discontinuations. Psychiatric side effects are heterogeneous and probably not related to pre-existing psychologic weakness. We do not have enough data to evaluate these side effects and their etiopathogeny. The drug could act directly on the central nervous system since it crosses the blood-brain barrier, on the serotoninergic and dopaminergic systems. Some authors have compared efavirenz-induced psychic effects to those associated with LSD and found structural similarities between the two molecules. However, the heterogeneity and low prevalence of the psychiatric side effects of efavirenz suggest and individual sensitivity. In order to improve patient care, a better clinical approach, neuropsychological evaluation, and functional brain imagery should be used to progress in the analysis and comprehension of these disorders.

    Full Text Available Previous research has shown an association between emotions, particularly social emotions, and moral judgments. Some studies suggested an association between blunted emotion and the utilitarian moral judgments observed in patients with prefrontal lesions. In order to investigate how prefrontal brain damage affects moral judgment, we asked a sample of 29 TBI patients (12 females and 17 males and 41 healthy participants (16 females and 25 males to judge 22 hypothetical dilemmas split into three different categories (non-moral, impersonal and personal moral. The TBI group presented a higher proportion of affirmative (utilitarian responses for personal moral dilemmas when compared to controls, suggesting an atypical pattern of utilitarian judgements. We also found a negative association between the performance on recognition of social emotions and the proportion of affirmative responses on personal moral dilemmas. These results suggested that the preference for utilitarian responses in this type of dilemmas is accompanied by difficulties in social emotion recognition. Overall, our findings suggest that deontological moral judgments are associated with normal social emotion processing and that frontal lobe plays an important role in both emotion and moral judgment.

    BACKGROUND: Focal nodular hyperplasia, a benign hepatic tumor, is usually asymptomatic. However, rarely the entity can cause symptoms, mandating intervention. METHOD: We present a case of focal nodular hyperplasia of the liver, which caused a considerable diagnostic dilemma due to its atypical presentation. RESULTS: A 29-year-old woman presented with a 15-year history of a progressively increasing mass in the right upper quadrant which was associated with pain and emesis. Examination showed a firm, mobile mass palpable below the right subcostal margin. A computed tomography scan of the abdomen showed an exophytic mass arising from hepatic segments III and IVb. Trucut biopsy of the hepatic mass was equivocal. Angiography showed a vascular tumor that was supplied by a tortuous branch of the proper hepatic artery. Surgical intervention for removal of the mass was undertaken. Intra-operatively, two large discrete tumors were found and completely resected. Histopathological examination showed features consistent with focal nodular hyperplasia. CONCLUSION: This description of an unusual case of focal nodular hyperplasia of the liver highlights the point that the diagnosis of otherwise benign hepatic tumors may be difficult despite extensive work-up in some cases.

    Although nocturnal disturbances are increasingly recognized as an integral part of the continuum of daytime manifestations of Parkinson's disease (PD), there is still little evidence in the medical literature to support the occurrence of these complex phenomena in patients with atypical parkinsonian disorders (APDs). Based on the anatomical substrates in APDs, which are considered to be more extensive outside the basal ganglia than in PD, we might expect that patients with APDs encounter the whole range of nocturnal disturbances, including motor, sleep disorders, autonomic dysfunctions, and neuropsychiatric manifestations at a similar, or even greater, frequency than in PD. This article is a review of the current literature on the problems at nighttime of patients with progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, and dementia with Lewy bodies. MEDLINE, life science journals and online books were searched by querying appropriate key words. Reports were included if the studies were related to nocturnal manifestations in APDs. Forty articles fulfilled the selection criteria. Differences between these symptoms in APDs and PD are highlighted, given the evidence available about each manifestation. This analysis of nocturnal manifestations of APDs suggests the need for future studies to address these issues to improve the quality of life not only of patients with APDs but the caregivers who encounter the challenges of supporting these patients on a daily basis.

  11. Frequency of a typical radiological pattern of pulmonary tuberculosis in adults and elderly (dissertation based article)

    International Nuclear Information System (INIS)

    Tuberculosis is one of the oldest diseases and one third of the world's population is affected. Typical pattern (infiltration and or nodules with or without cavitations involving upper zone lung field) of pulmonary tuberculosis is the most common mode of radiological presentation in adults. There is a trend towards a relative increase in the unusual radiological presentations. This study was conducted to determine the frequency of atypical radiological trend of pulmonary tuberculosis in adults and elderly. Subjects and Methods: The objective of the study was to determine frequency of a typical radiological pattern of pulmonary tuberculosis in adults and elderly. It was a descriptive (case series) study and was conducted in the Department of Pulmonology, Nishtar Hospital Multan. The study duration was six months from 24 May 2006 to 23 November 2006. 300 patients presenting with pulmonary tuberculosis were selected. History and clinical examination was done. Relevant investigations and x-ray chest were carried out. Lesions like infiltration with or without cavitation were localized in upper, middle and lower zones. Groups of patients with their x-ray findings in different zones were made and analyzed accordingly, data collected were entered in specific proforma. Results: 205 (97.6%) adults and 85 (94.4%) elderly presented with cough while 205 (97.6%) adults and 75 (83.3%) elderly presented with fever. Out of 300 cases infiltration was found in 141 (46.19% vs 48.88%) young adult and elderly cases. There were 99 cases with nodule (35.71% vs 26.66%) and 60 cases had cavitation (18.09% vs 24.44%). Conclusion: There is a trend towards a relative increase in the frequency of unusual radiological presentations which is more common in elderly. (author)

  12. Pancreatic Tuberculosis or Autoimmune Pancreatitis

    Full Text Available Introduction. Isolated pancreatic and peripancreatic tuberculosis is a challenging diagnosis due to its rarity and variable presentation. Pancreatic tuberculosis can mimic pancreatic carcinoma. Similarly, autoimmune pancreatitis can appear as a focal lesion resembling pancreatic malignancy. Endoscopic ultrasound-guided fine needle aspiration provides an effective tool for differentiating between benign and malignant pancreatic lesions. The immune processes involved in immunoglobulin G4 related systemic diseases and tuberculosis appear to have some similarities. Case Report. We report a case of a 59-year-old Southeast Asian male who presented with fever, weight loss, and obstructive jaundice. CT scan revealed pancreatic mass and enlarged peripancreatic lymph nodes. Endoscopic ultrasound-guided fine needle aspiration confirmed the presence of mycobacterium tuberculosis. Patient also had high immunoglobulin G4 levels suggestive of autoimmune pancreatitis. He was started on antituberculosis medications and steroids. Clinically, he responded to treatment. Follow-up imaging showed findings suggestive of chronic pancreatitis. Discussion. Pancreatic tuberculosis and autoimmune pancreatitis can mimic pancreatic malignancy. Accurate diagnosis is imperative as unnecessary surgical intervention can be avoided. Endoscopic ultrasound-guided fine needle aspiration seems to be the diagnostic test of choice for pancreatic masses. Long-term follow-up is warranted in cases of chronic pancreatitis.

This is worsened by the appearance of resistance to antitubercular agents. The WHO in its twentieth report notified that by 2014 there were 9.6 million new cases and 1.5 million of deaths due to this disease. Of these deaths 890.000 were men, 480.000 women and 140.000 children (1. 490.000 tuberculosis cases and 64.000 deaths with negative HIV were documented in children under the age of 15. For the multidrug-resistant tuberculosis in (TBMDR, the joint resistance to isoniazid and rifampin was 3.5% in new cases and 20.5% in previously treated cases (1. The illness is still a public health problem; therefore, it generates promotion and prevention activities with the purpose of stopping its spreading. One of the alternatives to prevent the spreading is the elaboration of vaccines against noxae in the human being. The Mycobacterium tuberculosis is a microorganism which is a part of the groups composed by: M. bovis, M. bovis BCG, M. canneti, M. pinnipedii, M. africanum, M. microti, M.caprae, M. mungi y M. orygis.

    1975-11-01

    The effect of immobilization on skeletal fluorosis was studied in growing rabbits. One hind leg was immobilized by an external fixation device extending below the wrist joint and above the knee joint, the extremity being in a straight position after severance of the sciatic nerve. The animals, aged 7 weeks at the beginning of the experiment, were given 10 mg of fluoride per kg body weight and day during 12 weeks. In the tibiae, development of the skeletal fluorosis was more irregular than that observed in previous studies of normally active animals, being most excessive in the mobile bone. The immobilization effect was most profound in the femora as the cortical thickness and the femur score were significantly higher than those in the mobile femora. It was suggested that an altered muscular activity was the reason for the observed changes. PMID:1189918

    Research on radiation detectors for absorptiometry; analysis of errors affective single photon absorptiometry and development of instrumentation; analysis of errors affecting dual photon absorptiometry and development of instrumentation; comparison of skeletal measurements with other techniques; cooperation with NASA projects for skeletal evaluation in spaceflight (Experiment MO-78) and in laboratory studies with immobilized animals; studies of postmenopausal osteoporosis; organization of scientific meetings and workshops on absorptiometric measurement; and development of instrumentation for measurement of fluid shifts in the human body were performed. Instrumentation was developed that allows accurate and precise (2% error) measurements of mineral content in compact and trabecular bone and of the total skeleton. Instrumentation was also developed to measure fluid shifts in the extremities. Radiation exposure with those procedures is low (2-10 MREM). One hundred seventy three technical reports and one hundred and four published papers of studies from the University of Wisconsin Bone Mineral Lab are listed.

    Skeletal fragility is a frequent complication of endogenous hypercortisolism, and fragility fractures may be the first clinical manifestation of the disease. Fractures involve more frequently the vertebrae and may occur in 30-50% of the patients exposed to glucocorticoid excess, in close relationship with severity and duration of hypercortisolism. Although improvement of bone mineral density was reported after resolution of hypercortisolism, there are patients with persistently high fracture risk after the cure of hypercortisolism, and other patients in whom the resolution of hypercortisolism may take a long time, implying a multistep therapeutic approach. Since vertebral fractures tend to occur early during the natural history of disease, a skeletal-specific approach should be undertaken in these patients; however, the cost-effectiveness of this approach is still largely unknown since data on effectiveness and safety of bone-active drugs in endogenous hypercortisolism are scarce.

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

    Full Text Available With the rapid increase in patients receiving bisphosphonates (BPs for treating osteoporosis, one of the clinical complications associated with its long-term use is atypical femoral fractures (AFFs. Although the absolute risk for AFFs is low and it was a consensus that AFFs were acceptable compared with the amount of osteoporotic fractures BPs have prevented, epidemiological studies have proved that BPs had a strong association with AFFs and possibly more people were going to suffer from this adverse effect with wide prescriptions of this drug. In addition, AFFs seemed to have impaired ability to heal. Thus, to understand the mechanism(s behind AFFs is important and desirable for considering preventive measures. This article reviewed the clinical features of AFFs as well as potential underlining pathological characteristics, such as the decreased turnover rate caused by BPs that led to multiple-level alternations, e.g., changes not only at cellular and tissue levels, but also related to changes in bone micro- and macrostructure and organic/inorganic contents, leading to potentially compromised mechanical properties of cortical bone when exposed to prolonged BP therapy. Severely suppressed bone turnover may also be the underlying mechanism for impaired fracture healing in patients with AFFs. The rising concerns about the risk for AFFs in nonosteoporotic patients receiving high-dose BPs to treat cancers were also discussed. Detailed investigation will help develop potential targeted pharmacological treatments such as parathyroid hormone. In addition, potential innovative internal fixation implants were discussed with regard to dynamic and biological fixation for enhancing AFF repair.

  19. Skeletal muscle: an endocrine organ.

    Pratesi, Alessandra; Tarantini, Francesca; Di Bari, Mauro

    2013-01-01

    Tropism and efficiency of skeletal muscle depend on the complex balance between anabolic and catabolic factors. This balance gradually deteriorates with aging, leading to an age-related decline in muscle quantity and quality, called sarcopenia: this condition plays a central role in physical and functional impairment in late life. The knowledge of the mechanisms that induce sarcopenia and the ability to prevent or counteract them, therefore, can greatly contribute to the prevention of disability and probably also mortality in the elderly. It is well known that skeletal muscle is the target of numerous hormones, but only in recent years studies have shown a role of skeletal muscle as a secretory organ of cytokines and other peptides, denominated myokines (IL6, IL8, IL15, Brain-derived neurotrophic factor, and leukaemia inhibitory factor), which have autocrine, paracrine, or endocrine actions and are deeply involved in inflammatory processes. Physical inactivity promotes an unbalance between these substances towards a pro-inflammatory status, thus favoring the vicious circle of sarcopenia, accumulation of fat - especially visceral - and development of cardiovascular diseases, type 2 diabetes mellitus, cancer, dementia and depression, according to what has been called "the diseasome of physical inactivity".

    2013-06-01

    This paper deals with the problem of optimal control of a deterministic model of tuberculosis (abbreviated as TB for tubercle bacillus). We first present and analyze an uncontrolled tuberculosis model which incorporates the essential biological and epidemiological features of the disease. The model is shown to exhibit the phenomenon of backward bifurcation, where a stable disease-free equilibrium co-exists with one or more stable endemic equilibria when the associated basic reproduction number is less than the unity. Based on this continuous model, the tuberculosis control is formulated and solved as an optimal control problem, indicating how control terms on the chemoprophylaxis and detection should be introduced in the population to reduce the number of individuals with active TB. Results provide a framework for designing the cost-effective strategies for TB with two intervention methods.

    Animal models are being developed for testing different vaccine candidates as well as testing of new antituber-cular since a long time.Mice,guinea pigs and rabbits are animals which are frequently used.Though each model has got its merits as well as demerits and each of them differ from human tuberculosis in one aspect or the other but none of the model completely mimics the human disease.Out of the different animal species, guinea pig model is one of the better models as it is very sensitive to M.tuberculosis infection but it has certain limitations like paucity of immunological reagents.However,it is the best model for tuberculosis research.

    Objective To review the transmission models of tuberculosis in heterogeneous population.Data sources The data used in this review were adopted mainly from the studies of models of tuberculosis reported from 1995 to 2006.Study selection Relevant literature on transmission models of tuberculosis in heterogeneous populations are referenced.Results Casual/random factors and genetic factors are the main reasons for epidemics of tuberculosis in recent years.Mass public transport is playing the primary role in casually close contact which can facilitate the transmission of tuberculosis. Genetic susceptibility not only varies endemic prevalence levels, but also drastically alters the effects of treatment for tuberculosis patients. Detailed studies further exhibit that casual contact and genetic factor are responsible for over 30%-40% of the total new cases in recent years. The prevalence of tuberculosis could double (from 33% to 60%)if a genetically susceptible phenotype is present in only 30% of the population. And some challenges have emerged along with these exciting results.Conclusions Casual/random contact, public transport and genetic susceptibility are responsible for most new tuberculosis cases and a wide variation in endemic tuberculosis levels between regions. Hence, the transmission model of tuberculosis in a heterogeneous population can provide more clues to underlying mechanism of tuberculosis transmission than in a homogeneous population. However, many challenges remain for us in understanding transmission of disease.

    We studied 20 patients with intraspinal tuberculosis (TB), to characterise the MRI features of tuberculous meningitis and myelitis. MRI leptomeningitis and intramedullary involvement in 11 patients, intramedullary lesions alone in 5, leptomeningitis alone in 2, and isolated extradural disease in 2. TB leptomeningitis was characterised by loculation of the cerebrospinal fluid (CSF), nerve root thickening and clumping (seen only in the lumbar region) or complete obliteration of the subarachnoid space on unenhanced images. Gd-DTPA-enhanced images proved useful in 6 cases, revealing linear enhancement of the surface of the spinal cord and nerve roots or plaque-like enhancement of the dura-arachnoid mater complex. Intramedullary lesions included tuberculomas (8), cord oedema (5) and cavitation (3). In seven cases of intramedullary tuberculoma multiple lesions with skip areas were seen, without significant cord swelling. One patient had an isolated lesion in the conus medullaris. The lesions were iso- or hypointense on T1-weighted images, iso-, hypo- or hyperintense on T2-weighted images and showed rim or nodular enhancement with contrast medium. (orig.)

  5. Tuberculosis in Aboriginal Canadians

    Full Text Available Endemic tuberculosis (TB was almost certainly present in Canadian aboriginal people (aboriginal Canadians denotes status Indians, Inuit, nonstatus Indians and metis as reported by Statistics Canada before the Old World traders arrived. However, the social changes that resulted from contact with these traders created the conditions that converted endemic TB into epidemic TB. The incidence of TB varied inversely with the time interval from this cultural collision, which began on the east coast in the 16th century and ended in the Northern Territories in the 20th century. This relatively recent epidemic explains why the disease is more frequent in aboriginal children than in Canadian-born nonaboriginal people. Treatment plans must account for the socioeconomic conditions and cultural characteristics of the aboriginal people, especially healing models and language. Prevention includes bacillus Calmette-Guerin vaccination and chemoprophylaxis, and must account for community conditions, such as rates of suicide, which have exceeded the rate of TB. The control of TB requires a centralized program with specifically directed funding. It must include a program that works in partnership with aboriginal communities.

  6. Tuberculosis in complex emergencies.

    Science.gov (United States)

    Coninx, Rudi

    2007-08-01

    This paper describes the key factors and remaining challenges for tuberculosis (TB) control programmes in complex emergencies. A complex emergency is "a humanitarian crisis in a country, region or society where there is total or considerable breakdown of authority resulting from internal or external conflict and which requires an international response that goes beyond the mandate or capacity of any single agency and/or the ongoing United Nations country programme." Some 200 million people are believed to live in countries affected by complex emergencies; almost all of these are developing countries that also bear the main burden of TB. The effects of complex emergencies impact on TB control programmes, interfering with the goals of identifying and curing TB patients and possibly leading to the emergence of MDR-TB. There are many detailed descriptions of aid interventions during complex emergencies; yet TB control programmes are absent from most of these reports. If TB is neglected, it may quickly result in increased morbidity and mortality, as was demonstrated in Bosnia and Herzegovina and in Somalia. TB is a major disease in complex emergencies and requires an appropriate public health response. While there is no manual to cover complex emergencies, the interagency manual for TB control in refugee and displaced populations provides valuable guidance. These programmes contribute to the body of evidence needed to compile such a manual, and should ensure that the experiences of TB control in complex emergencies lead to the establishment of evidence-based programmes.

    Results: 18 patients had evidence of pulmonary tuberculosis. 5 patients had active disease and 13 patients had evidence of healed pulmonary tuberculosis. The prevalence of pulmonary tuberculosis was 8.3%. This is much higher than the prevalence in the Indian population which is 13-25 per thousand. Of the 5 patients who had active disease 3 patients were on leflunamide for 1 year or more. On analysis it was found that patients on leflunamide were at an increased risk of developing tuberculosis (p <0.001 and the risk estimate showed an odds ratio of 14.2. Conclusions: Prevalence of pulmonary tuberculosis in the study population was found to be 8.3%. In countries with high prevalence of latent and active tuberculosis, rheumatoid arthritis patients should be carefully monitored for pulmonary tuberculosis before and during the treatment with immunosuppressive drugs.

  11. Ultrasonographic and CT findings of hepatosplenic tuberculosis

    International Nuclear Information System (INIS)

    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

    Increased skeletal muscle capillarization is associated with improved glucose tolerance and insulin sensitivity. However, a possible causal relationship has not previously been identified. We therefore investigated whether increased skeletal muscle capillarization increases insulin sensitivity......-body insulin sensitivity increased by ~24% and insulin-stimulated skeletal muscle 2-deoxy-[(3)H]-Glucose disposal increased by ~30% concomitant with a ~20% increase in skeletal muscle capillarization. Adipose tissue insulin sensitivity was not affected by the treatment. Insulin-stimulated muscle glucose uptake...... the rats on any other parameters measured. We conclude that an increase in skeletal muscle capillarization is associated with increased insulin sensitivity. These data point towards the importance of increasing skeletal muscle capillarization for prevention or treatment of type 2 diabetes....

    Full Text Available The skeletal muscle is the second more plastic tissue of the body - second to the nervous tissue only. In fact, both physical activity and inactivity contribute to modify the skeletal muscle, by continuous signaling through nerve impulses, mechanical stimuli and humoral clues. In turn, the skeletal muscle sends signals to the body, thus contributing to its homeostasis. We'll review here the contribute of physical exercise to the shaping of skeletal muscle, to the adaptation of its mass and function to the different needs imposed by different physical activities and to the attainment of the health benefits associated with active skeletal muscles. Focus will primarily be on the molecular pathways and on gene regulation that result in skeletal muscle adaptation to exercise.

    The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were

    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 crucial opportunity to interrupt tuberculosis transmission and reduce the global burden of tuberculosis disease. Programmes focusing on single strategies rather than comprehensive programmes that deliver an integrated arsenal for tuberculosis control might continue to struggle. Tuberculosis preventive therapy is a poorly used method that is essential for controlling the reservoirs of disease that drive the 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. In this Series paper we outline challenges to implementation of preventive therapy and provide pragmatic suggestions for overcoming them. We further advocate for tuberculosis preventive therapy as the core of a renewed worldwide 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 and community engagement, and enhance sustainable large scale implementation of preventive therapy programmes.

The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

  2. Chemotherapy of osteoarticular tuberculosis

    Full Text Available Tuberculosis (TB of the bones and joints is rampant in India with the dorsolumbar spine as the most common site of osseous involvement. For diagnosis, clinical suspicion needs to be confirmed through appropriate laboratory and imaging investigations, and increasingly nowadays, nucleic acid amplification techniques. Chemotherapy remains the cornerstone of management complemented by rest, nutritional support and splinting, as necessary. Operative intervention is required if response to chemotherapy is unsatisfactory and for spinal stabilization. The drugs and regimens are fundamentally similar to those for pulmonary TB. However, there is lack of consensus on the appropriate duration of treatment. The prevailing practice of extending treatment till radiological evidence of healing is complete, may be unnecessary in view of recent reports that 6-9 months of therapy is sufficient for the majority of cases. Relapse rates are not drastically improved by extending treatment to 12 months or even longer, except perhaps in pediatric cases. However, prolonged treatment may be required if surgical debridement is indicated but cannot be done. Multidrug-resistant TB should be suspected if disease activity shows no signs of abating after 4-6 months of uninterrupted therapy. These cases are therapeutically challenging and will require second line or experimental antiTB drugs, supported by resistance testing where feasible. Coexistent HIV/AIDS may also necessitate prolonged treatment. Interactions between first line antiTB drugs and antiretroviral medication can complicate matters. Close monitoring is essential in all cases, with dechallenge and cautious reinstitution of drugs in the event of toxicity. While awaiting the arrival of long overdue new antiTB medication, existing drugs and regimens must be used in an informed manner with emphasis on patient compliance.

  3. New tuberculosis vaccines.

    2011-03-01

    The current tuberculosis (TB) vaccine, bacille Calmette-Guerin (BCG), is a live vaccine used worldwide, as it protects against severe forms of the disease, saving thousands of lives every year, but its efficacy against pulmonary forms of TB, responsible for transmission of the diseases, is variable. For more than 80 years now no new TB vaccines have been successfully developed. Over the last decade the effort of the scientific community has resulted in the design and construction of promising vaccine candidates. The goal is to develop a new generation of vaccines effective against respiratory forms of the disease. We will focus this review on new prophylactic vaccine candidates that aim to prevent TB diseases. Two are the main strategies used to improve the immunity conferred by the current BCG vaccine, by boosting it with new subunit vaccines, and a second strategy is focused on the construction of new more effective live vaccines, capable to replace the current BCG and to be used as prime vaccines. After rigorous preclinical studies in different animal models new TB vaccine candidates enter in clinical trials in humans. First, a small Phase I for safety followed by immunological evaluation in Phase II trials and finally evaluated in large population Phase III efficacy trials in endemic countries. At present BCG prime and boost with different subunit vaccine candidates are the more advanced assessed in Phase II. Two prime vaccines (based on recombinant BCG) have been successfully evaluated for safety in Phase I trials. A short number of live attenuated vaccines are in advance preclinical studies and the candidates ready to enter Phase I safety trials are produced under current good manufacturing practices.

  5. Facing multi-drug resistant tuberculosis.

    Sotgiu, Giovanni; Migliori, Giovanni Battista

    2015-06-01

    Multi-drug resistant tuberculosis (MDR-TB) is caused by Mycobacterium tuberculosis strains resistant to at least two of the most effective anti-tuberculosis drugs (i.e., isoniazid and rifampicin). Therapeutic regimens based on second- and third-line anti-tuberculosis medicines showed poor efficacy, safety, and tolerability profiles. It was estimated that in 2012 the multi-drug resistant tuberculosis incidence ranged from 300,000 to 600,000 cases, mainly diagnosed in the Eastern European and Central Asian countries. The highest proportion of cases is among individuals previously exposed to anti-tuberculosis drugs. Three main conditions can favour the emergence and spread of multi-drug resistant tuberculosis: the poor implementation of the DOTS strategy, the shortage or the poor quality of the anti-tuberculosis drugs, and the poor therapeutic adherence of the patients to the prescribed regimens. Consultation with tuberculosis experts (e.g., consilium) is crucial to tailor the best anti-tuberculosis therapy. New therapeutic options are necessary: bedaquiline and delamanid seem promising drugs; in particular, during the development phase they demonstrated a protective effect against the emergence of further resistances towards the backbone drugs. In the recent past, other antibiotics have been administered off-label: the most relevant efficacy, safety, and tolerability profile was proved in linezolid-, meropenem/clavulanate-, cotrimoxazole-containing regimens. New research and development activities are needed in the diagnostic, therapeutic, preventive fields. PMID:24792579

    2008-11-01

    The global impact of the converging dual epidemics of tuberculosis (TB) and human immunodeficiency virus (HIV) is one of the major public health challenges of our time. The World Health Organization (WHO) reports 9.2 million new cases of TB in 2006 of whom 7.7% were HIV-infected. Tuberculosis is the most common opportunistic infection in HIV-infected patients as well as the leading cause of death. Further, there has been an increase in rates of drug resistant tuberculosis, including multi-drug (MDRTB) and extensively drug resistant TB (XDRTB), which are difficult to treat and contribute to increased mortality. The diagnosis of TB is based on sputum smear microscopy, a 100-year old technique and chest radiography, which has problems of specificity. Extra-pulmonary, disseminated and sputum smear negative manifestations are more common in patients with advanced immunosuppression. Newer diagnostic tests are urgently required that are not only sensitive and specific but easy to use in remote and resource-poor settings. Treatment of HIV-TB co-infection is complex and associated with high pill burden, overlapping drug toxicities, risk of immune reconstitution inflammatory syndrome (IRIS) and challenges related to adherence. From a programmatic point of view, screening of all HIV-infected persons for tuberculosis and vice-versa will help identify co-infected patients who require treatment for both infections. This requires good coordination and communication between the TB and AIDS control programs, in India.

    Full Text Available Tuberculosis (TB has been a disease affecting almost all parts of the world since ages. Lot many efforts came in the past for improving diagnosis and treatment. Also, an effective vaccine has been sought after for long. With the emergence of resistant strains of Mycobacterium tuberculosis, the causal organisms of tuberculosis, and complexities emerging due to other associated infections and disease conditions, there is a desperate need for further research input in the field. Be it the better medication and care or better resistance management, proper diagnostics holds the key to success. It has been observed that a high burden of the disease was accompanied by resource limitations and poor research set-up. The scenario remained like this for several decades. With the refreshed vision of resourceful countries and funding agencies, funding is being provided in many areas of research in tuberculosis diagnosis and treatment. This review has been written with an aim to bring forth the limitations of available methods in the field of diagnostics and making researchers aware about the changing scenario with better funding opportunities and support. The author visualizes an enthusiasm from all over the world for the development of better modalities and urges scientists to join the struggle at this very perfect time to take the challenge and come forward with innovations in this field.

    Full Text Available Getahun Abate,1 Daniel F Hoft1,2 1Department of Internal Medicine, Division of Infectious Diseases, Allergy and Immunology, 2Department of Molecular Microbiology and Immunology, Saint Louis University, St. Louis, MO, USA Abstract: Tuberculosis (TB is still a major global health problem. A third of the world's population is infected with Mycobacterium tuberculosis. Only ~10% of infected individuals develop TB but there are 9 million TB cases with 1.5 million deaths annually. The standard prophylactic treatment regimens for latent TB infection take 3–9 months, and new cases of TB require at least 6 months of treatment with multiple drugs. The management of latent TB infection and TB has become more challenging because of the spread of multidrug-resistant and extremely drug-resistant TB. Intensified efforts to find new TB drugs and immunotherapies are needed. Immunotherapies could modulate the immune system in patients with latent TB infection or active disease, enabling better control of M. tuberculosis replication. This review describes several types of potential immunotherapies with a focus on those which have been tested in humans. Keywords: tuberculosis, HDT, immunotherapy, treatment

    Full Text Available Background/Objective: The incidence of primary CNS lymphomas (PCNSL is increasing. Timely diagnosis of PCNSL can lead to proper therapeutic management. There are some atypical imaging findings that may easily be misdiagnosed as other pathologic processes such as infectious and demyelinative diseases. As a result, histopathologic diagnosis is necessary for all suspected lesions."nPatients and Methods: In this research we studied 120 cases of PCNSL over the past 16 years. Some of them had atypical imaging findings, suggesting many differential diagnoses. Having said that, stereotactic biopsy was performed for all cases and the diagnosis was proved."nResults: We selected some interesting cases with atypical imaging findings of PCNSL, which were unlikely to be diagnosed without histopathologic evaluation. "nConclusion: PCNSL must be kept in mind as a differential diagnosis for other brain lesions. Histopathologic diagnosis is necessary for prompt management.

  16. EPR dosimetry with synthetic A-type carbonated apatite

    International Nuclear Information System (INIS)

    Synthetic A-type carbonated apatite prepared in reproducible conditions were irradiated at room temperature with 60 Co γ rays. The EPR spectrum is associated to axial CO2- and orthorhombic CO3- species. Radicals used as dose marker in biological apatite are long live paramagnetic species. The stability of the post-irradiation signal of A-type apatite was investigated for more than one year. Measurements showed variations in the spectra attributed to unstable CO3- species, which can be eliminated by thermal treatments at 100 deg C for 24 hours. The CO2- spectrum can be identified in samples irradiated up to 0.2 Gy. All results indicate the A-type apatite as an appropriate material for radiotherapy dosimetry. (author)

    2007-01-01

    Full Text Available Background. Atypical forms of pyoderma gangrenosum generally appear on the upper extremities; most frequently they are associated with myeloproliferative disorders, including osteomyelofibrosis. A response to systemic steroids is more pronounced than in classical form. Sometimes it may be the first sign of an underlying malignancy. Case report. We reported a patient with atypical pyoderma gangrenosum developed during the course of a myeloid malignancy - osteomyelofibrosis. The lesions occurred after a minor trauma. Painful blistering plaques, with an elevated, bluish-gray border were located on the dorsal aspect of hands. No skin malignancy was found. The lesions resolved rapidly to systemic steroids. Conclusion. Considering the unusual clinical presentation which makes the diagnosis difficult, as well as the fact that atypical forms of pyoderma gangrenosum can be the first sign of malignancies, especially myeloproliferative ones, recognizing this entity enables timely guiding future investigations toward their prompt detection.

    Braulio Sastre-Jala

    2015-10-01

    Full Text Available Atypical fractures related to the prolonged use of bisphosphonates are caused by low energy mechanisms and are characterized by oblique and transverse lines and frequent bilateralism. We present a clinical case of a patient who we believe illustrates, both in clinical and radiological aspects, the new definition of atypical femur fracture related to treatment using bisphosphonates treated conservatively and successfully with discharge and teriparatide 20 mcg/80 mcl s.c./24h. The appearance of painful symptoms in the upper thigh, especially if bilateral, in patients treated with bisphosphonates for long periods of time, makes it necessary to dismiss bone lesions that might otherwise suggest atypical fracture. In those cases where the fracture is incomplete, restoring bone metabolism through the administration of teriparatide 20 mcg/80 mcl s.c./24h could prevent displaced fractures.

    Full Text Available Tuberculosis is a diffusive infectious disease whose typical behavior differentiates it from other infectious diseases spread by human-to-human transmission (flu, chicken pox, cholera, etc. which follow a classically epidemic pattern. Indeed, in the presence of a known source of Koch bacilli capable of spreading them by air, not all exposed individuals inhale the bacteria, not all those who inhale them absorb them, not all those who absorb them are unable to eliminate them, not all who are able to eliminate them do so using delayed hypersensitivity, not all those who react with delayed hypersensitivity suffer lasting tissue damage (among other things, minor, not all who suffer tissue damage have anatomical sequelae, not all those who have anatomical sequelae, however minimal, become carriers of bacilli in the latent period. The vast majority (90-95% of the latter – which are in any case a portion, not the totality of those exposed – remain asymptomatic throughout their lives and never develop active tuberculosis. Based on these biological characteristics and the legal concepts of “epidemic” and “disease,” it becomes highly problematic, if not impossible, to assert both that tuberculosis can cause events of sufficient magnitude to be associated with the crime of “epidemic,” and that the mere diagnosis of a latent tuberculosis infection is sufficient to assume the presence of an illness legally prosecutable in criminal proceedings or a disability prosecutable in civil proceedings. Further, clinically apparent tuberculosis is a temporarily—in some cases permanently—disabling condition, and in certain work environments, even with the difficulties caused by the lack of available effective diagnostic tools and the insidious behavior of the disease in the early stages, it appears appropriate to engage in targeted monitoring, also for the early identification of persons who may become ill.

    Full Text Available Neuroleptic malignant syndrome (NMS is the most serious of acute neurological side effects produced by antipsychotic medication, characterized by hyperthermia, rigidity, altered consciousness and autonomic dysfunction, the prevalence of which varies from 0.4-1.4%. NMS is usually seen in treatment with high potency typical antipsychotics and very rarely with atypical antipsychotics. However, NMS cases have been reported with risperidone, clozapine, olanzapine and quetiapine. The presentations of NMS have often varied, and we report another atypicality in presentation of NMS due to olanzapine use.

    Full Text Available Background. Biomarkers to distinguish latent from active Mycobacterium (M. tuberculosis infection in clinical practice are lacking. The urinary neopterin/creatinine ratio can quantify the systemic interferon-gamma effect in patients with M. tuberculosis infection. Methods. In a prospective observational study, urinary neopterin levels were measured by enzyme linked immunosorbent assay in patients with active tuberculosis, in people with latent M. tuberculosis infection, and in healthy controls and the urinary neopterin/creatinine ratio was calculated. Results. We included a total of 44 patients with M. tuberculosis infection and nine controls. 12 patients had active tuberculosis (8 of them culture-confirmed. The median age was 15 years (range 4.5 to 49. Median urinary neopterin/creatinine ratio in patients with active tuberculosis was 374.1 micromol/mol (129.0 to 1072.3, in patients with latent M. tuberculosis infection it was 142.1 (28.0 to 384.1, and in controls it was 146.0 (40.3 to 200.0, with significantly higher levels in patients with active tuberculosis (p<0.01. The receiver operating characteristics curve had an area under the curve of 0.84 (95% CI 0.70 to 0.97 (p<0.01. Conclusions. Urinary neopterin/creatinine ratios are significantly higher in patients with active tuberculosis compared to patients with latent infection and may be a significant predictor of active tuberculosis in patients with M. tuberculosis infection.

    Full Text Available Disseminated tuberculosis is a common mode of presentation of tuberculosis in patients both with and without HIV/AIDS in India. However, primary multidrug resistance in disseminated tuberculosis involving only the extrapulmonary sites in an immunocompetent adult is rare. Here, we report a case of a 19-year-old man who had disseminated tuberculosis involving left pleura, pericardium, peritoneum and intraabdominal lymph nodes. He was initially taking WHO category I antituberculous drugs, but was not responding in spite of 5 months of chemotherapy. Culture of the pleural biopsy specimen grew Mycobacterium tuberculosis which was resistant to isoniazid and rifampicin. He was put on therapy for multidrug resistant tuberculosis,following 24 months of chemotherapyhe had an uneventful recovery.

    Full Text Available Tuberculosis of the cervix is a rare disease and accounts to 0.1 – 0.65% of all cases of tuberculosis and 5 – 24 % of genital tract tuberculosis. We present an unusual case of 40 years old lady who presented with irregular bleeding per vagina and foul smelling white discharge for 1 year. Per speculum examination revealed an unhealthy looking cervix which bled on touch. A clinical diagnosis of carcinoma cervix was made. However, cervix biopsy revealed granulomatous lesion suggestive of tuberculosis. The patient responded to antitubercular therapy. In women with abnormal cervical appearance, there should be high index of suspicion of tuberculosis cervix, especially from areas where tuberculosis is common as it can be easily treated.

    A clinical observation was made on 30 cases of urogenital tuberculosis diagnosed and treated at the urological department of our Hospital between January, 1976 and December, 1984. Furthermore, 20 of them were examined for drug resistance and investigated for this tendency. They accounted for 0.23% of the outpatients. Male to female ratio was 2 to 1, but on urological tuberculosis this ratio was even. The average age was 43.7 and 50% of the patients who had a history of tuberculosis. Mycobacterium tuberculosis could be detected in 24 of the 30 cases (80%) and 18 of the 21 cases (85.4%) of urological tuberculosis. Drug resistance was examined in 20 patients. The resistant ratio of M. tuberculosis against primary drugs such as SM, PAS, INAH was low and a high resistant ratio was observed on secondary drugs such as EB, RFP, TH. These clinical observations are reported and herein discussed.

    2014-01-01

    Objective This study aimed to review the available literatures on control of latent tuberculosis (TB) infection and propose a new control strategy to shorten the course of TB chemotherapy.Data sources The data used in this review were mainly obtained from articles listed in PubMed.The search terms were "therapy (treatment) of tuberculosis," "therapy (treatment) of latent TB infection," and "vaccine of TB."Study selection Articles regarding treatment and vaccine of TB were selected and reviewed.Results The most crucial reason causing the prolonged course of TB chemotherapy is the dormant state of Mycobacterium tuberculosis (M.tuberculosis).Nevertheless,there are,to date,no effective drugs that can directly kill the dormant cells of M.tuberculosis in clinical therapy.In accordance with the growth cycle of dormant M.tuberculosis in the body,the methods for controlling dormant M.tuberculosis include direct killing with drugs,prevention of dormant M.tuberculosis resuscitation with vaccines,and resuscitating dormant M.tuberculosis with preparations or drugs and then thoroughly killing these resuscitated M.tuberculosis by using anti-TB therapy.Conclusions The comprehensive analysis of the above three methods suggests that the drugs directly killing dormant cells are in clinical trials,TMC207 is the most beneficial for controlling TB.Because the side effect of vaccines is less and their action period is long,prevention of dormant cells resuscitation with vaccines is promising.The last control method makes it probable that when a huge number of active cells of M.tuberculosis have been killed and eradicated after 1-month short chemotherapy,only a strong short-term subsequent chemotherapy can completely kill and eradicate the remaining M.tuberculosis.This control strategy is expected to significantly shorten the course of TB chemotherapy and bring a new change and breakthrough in TB treatment.

  20. Defective skeletal mineralization in pediatric CKD.

    Science.gov (United States)

    Wesseling-Perry, Katherine

    2015-04-01

    Although traditional diagnosis and treatment of renal osteodystrophy focused on changes in bone turnover, current data demonstrate that abnormalities in skeletal mineralization are also prevalent in pediatric chronic kidney disease (CKD) and likely contribute to skeletal morbidities that continue to plague this population. It is now clear that alterations in osteocyte biology, manifested by changes in osteocytic protein expression, occur in early CKD before abnormalities in traditional measures of mineral metabolism are apparent and may contribute to defective skeletal mineralization. Current treatment paradigms advocate the use of 1,25(OH)2vitamin D for the control of secondary hyperparathyroidism; however, these agents fail to correct defective skeletal mineralization and may exacerbate already altered osteocyte biology. Further studies are critically needed to identify the initial trigger for abnormalities of skeletal mineralization as well as the potential effects that current therapeutic options may have on osteocyte biology and bone mineralization.

  1. Assessment of mandibular growth by skeletal scintigraphy

    International Nuclear Information System (INIS)

    Accurate assessment of facial skeletal growth remains a major problem in craniomaxillofacial surgery. Current methods include: (1) comparisons of chronologic age with growth histories of the patient and the family, (2) hand-wrist radiographs compared with a standard, and (3) serial cephalometric radiographs. Uptake of technetium-99m methylene diphosphonate into bone is a reflection of current metabolic activity and blood flow. Therefore, scintigraphy with this radiopharmaceutical might serve as a good method of assessing skeletal growth. Thirty-four patients, ranging in age from 15 months to 22 years, who were undergoing skeletal scintigrams for acute pathologic conditions of the extremities, were used to develop standards of uptake based on age and skeletal maturation. The results indicate that skeletal scintigraphy may be useful in evaluation of mandibular growth

    Dormancy models for Mycobacterium tuberculosis play important roles in understanding various aspects of tuberculosis pathogenesis and in the testing of novel therapeutic regimens. By simulating the latent tuberculosis infection, in which the bacteria exist in a non-replicative state, the models demonstrate reduced susceptibility to antimycobacterial agents. This minireview outlines the models available for simulating latent tuberculosis both in vitro and in several animal species. Additionally, this minireview discusses the advantages and disadvantages of these models for investigating the bacterial subpopulations and susceptibilities to sterilization by various antituberculosis drugs.

    Full Text Available The authors reports two patients with operated from enteric tuberculosis. Tuberculosis involving the intestinal tract may be due to either Mycobacterium tuberculosis or M. bovis. In the former situation, the disease is primary to the lungs and is carried to the intestinal tract by swallowing sputum. The latter organism produces infection associated with swallowed nonpasteurized milk. This condition is extremely unusual in most western countries, since pasteurization of milk is standardized. The diagnosis was performed through laparotomy because of symptoms suggestive of intestine obstruction. Inflammatory reactions were observed on the small intestine (jejunum-ileum in both cases. The presence of tuberculosis of the lungs was observed in one patient. The chemotherapic treatment was estabilished after the histopathologic diagnosis. The distinction between tuberculosis and Crohn's disease may not be possible by radiography or endoscopy. Videolaparoscopy has been found to be an useful procedure for the early diagnosis of Enteric Tuberculosis. In spite of the epidemiology knowledge, clinical control and improvement in treatment, extra pulmonary tuberculosis rate from concealed focus has been increased, due to AIDS poverty in certain populational groups and immigration from Asia to wertern countries. Compared with immunocompetent patients, the proportion of extrapulmonary tuberculosis is much higher in patients with AIDS, justfying the increased frequency of reports of intestinal tuberculosis in these patients.

    The rates of tuberculosis remain high in urban areas. The declining speed of tuberculosis incidence rate in urban areas has been slower than other areas. Efforts and resources to tuberculosis control must be concentrated on urban locations to eradicate tuberculosis in Japan. 1. Tuberculosis control in a public health center of urban area: Teru OGURA and Chiyo INOGUCHI (Toshima City, Ikebukuro Public Health Center, Tokyo Metropolitan) A wide range of TB control measures is implemented by public health centers, such as a patient registration, home-visit guidance, contact examination in urban areas. Directors of every health center have the direct responsibility for tuberculosis control measures in their jurisdiction. Ikebukuro is urban areas where there are many offices, shopping and amusement facilities. Urban people is often on the move looking for job, so public health centers are often not easy to carry out contact examinations as planned. In recent years, homelessness has been recognized as a growing urban social problem. Their incidence of tuberculosis is high. Special TB control program must be carried out in urban areas. 2. Tuberculosis Control in Tokyo Metropolitan: Kazumasa MATSUKI (Department of Infectious Diseases and Tuberculosis, Bureau of Public Health, Tokyo Metropolitan) There has been a steady decline in the TB wards. The beds for TB patients are running short and even smear positive TB cases cannot be put in a hospital without waiting several days. Staffs of an urban emergency department must protect tuberculosis infection by environmental controls of emergency room. Tokyo Metropolitan government supports the engineering improvements of emergency room to hospitals. Directly observed therapy for tuberculosis patients at a district has been implemented to complete their therapy. On DOT, a trained health worker observes the patient take anti-TB medication. 3.

    Full Text Available Aim: To explore the methods for achieving pain relief in patients with atypical trigeminal neuralgia (TN using microvascular decompression (MVD. Study Design and Settings: Retrospective study of 26 patients treated during the years 2000 to 2004. Materials and Methods: Twenty-six patients in whom vascular compression of the trigeminal nerve was identified by high definition magnetic resonance tomographic angiography (MRTA were treated with MVD for atypical TN in our department. Clinical presentations, surgical findings and clinical outcomes were analyzed retrospectively. Results: In this study, single trigeminal division was involved in only 2 patients (8% and two or three divisions in the other 24 patients (92%. Of prime importance is the fact that in 46.2% of the patients, several conflicting vessels were found in association. Location of the conflicts around the circumference of the trigeminal root was supero-medial to the root in 53.5%, supero-lateral in 30.8% and inferior in 15.7%. MVD for atypical TN resulted in complete pain relief in 50% of the patients with complete decompression, partial pain relief in 30.8% and poor pain relief or pain recurrence in 19.2% of the patients without complete decompression postoperatively. Conclusions: Complete decompression of the entire trigeminal root plays an important role in achieving pain relief in patients with atypical TN with MVD.

    2015-01-01

    Copper (Cu) is a trace element essential for the growth and development of almost all organisms, including bacteria. However, Cu overload in most systems is toxic. Studies show Cu accumulates in macrophage phagosomes infected with bacteria, suggesting Cu provides an innate immune mechanism to combat invading pathogens. To counteract the host-supplied Cu, increasing evidence suggests that bacteria have evolved Cu resistance mechanisms to facilitate their pathogenesis. In particular, Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, has evolved multiple pathways to respond to Cu. Here, we summarize what is currently known about Cu homeostasis in Mtb and discuss potential sources of Cu encountered by this and other pathogens in a mammalian host. PMID:25614981

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    Tuberculosis control relies on the identification and preventive treatment of individuals who are latently infected with Mycobacterium tuberculosis. However, direct identification of latent tuberculosis infection is not possible. The diagnostic tests used to identify individuals latently infected...... with M. tuberculosis, the in vivo tuberculin skin test and the ex vivo interferon-gamma release assays (IGRAs), are designed to identify an adaptive immune response against, but not necessarily a latent infection with, M. tuberculosis. The proportion of individuals who truly remain infected with M....... tuberculosis after tuberculin skin test or IGRA conversion is unknown.

    The WHO declared tuberculosis (TB) a global emergency. An estimated 8-9 million new cases occur each year with 2-3 million deaths. Currently, TB is diagnosed mostly by chest-X ray and staining of the mycobacteria in sputum with a detection limit of 1x104 bacteria /ml. There is an urgent need for better diagnostic tools for TB especially for developing countries. We have validated the electronic nose from TD Technology for the detection of Mycobacterium tuberculosis by headspace analysis of 284 sputum samples from TB patients. We used linear discriminant function analysis resulting in a sensitivity of 75% a specificity of 67% and an accuracy of 69%. Further research is still required to improve the results by choosing more selective sensors and sampling techniques. We used a fast gas chromatography- mass spectrometry method (GC-MS). The automated procedure is based on the injection of sputum samples which are methylated inside the GC injector using thermally assisted hydrolysis and methylation (THM-GC-MS). Hexacosanoic acid in combination with tuberculostearic acid was found to be specific for the presence of M. tuberculosis. The detection limit was similar to microscopy. We found no false positives, all microscopy and culture positive samples were also found positive with the THM-GC-MS method. The detection of ribosomal RNA from the infecting organism offers great potential since rRNA molecules outnumber chromosomal DNA by a factor 1000. It thus may possible to detect the organism without amplification of the nucleic acids (NA). We used a capture and a tagged detector probe for the direct detection of M. tuberculosis in sputum. So far the detection limit is 1x106 bacteria / ml. Currently we are testing a Lab-On-A-Chip Interferometer detection system.

  1. Ancient skeletal evidence for leprosy in India (2000 B.C..

    Directory of Open Access Journals (Sweden)

    Gwen Robbins

    Full Text Available BACKGROUND: Leprosy is a chronic infectious disease caused by Mycobacterium leprae that affects almost 250,000 people worldwide. The timing of first infection, geographic origin, and pattern of transmission of the disease are still under investigation. Comparative genomics research has suggested M. leprae evolved either in East Africa or South Asia during the Late Pleistocene before spreading to Europe and the rest of the World. The earliest widely accepted evidence for leprosy is in Asian texts dated to 600 B.C. METHODOLOGY/PRINCIPAL FINDINGS: We report an analysis of pathological conditions in skeletal remains from the second millennium B.C. in India. A middle aged adult male skeleton demonstrates pathological changes in the rhinomaxillary region, degenerative joint disease, infectious involvement of the tibia (periostitis, and injury to the peripheral skeleton. The presence and patterning of lesions was subject to a process of differential diagnosis for leprosy including treponemal disease, leishmaniasis, tuberculosis, osteomyelitis, and non-specific infection. CONCLUSIONS/SIGNIFICANCE: Results indicate that lepromatous leprosy was present in India by 2000 B.C. This evidence represents the oldest documented skeletal evidence for the disease. Our results indicate that Vedic burial traditions in cases of leprosy were present in northwest India prior to the first millennium B.C. Our results also support translations of early Vedic scriptures as the first textual reference to leprosy. The presence of leprosy in skeletal material dated to the post-urban phase of the Indus Age suggests that if M. leprae evolved in Africa, the disease migrated to India before the Late Holocene, possibly during the third millennium B.C. at a time when there was substantial interaction among the Indus Civilization, Mesopotamia, and Egypt. This evidence should be impetus to look for additional skeletal and molecular evidence of leprosy in India and Africa to confirm

  2. Analsysis of frequency of tuberculosis in smokers

    Škodrić-Trifunović Vesna

    2013-01-01

    Full Text Available Introduction. Smoking and tuberculosis are among the most important problems of public health. Smoking and tuberculosis are responsible for 5 million and 2 million deaths per year, respectively, whereas smoking is responsible for half a million deaths in patients with tuberculosis. Discussion and Review of Literature. Nicotine is a significant suppressor of function of macrophages, dendritic cells and T-cells, which explains the immunosuppressive features of smoking that help develop the infection. Tobacco smoke contains many substances with immunomodulatory effects, including nicotine, carbon monoxide, acrolein, peroxynitrite and many others. The dominant immune and pathophysiological mechanism is the reduction of synthesis of tumor necrosis factor in lung macrophages, leading to increased susceptibility of persons who are exposed to tobacco smoke for developing active tuberculosis after infection and increased susceptibility to the development of other infections, such as infections of Gram-negative bacteria. Based on epidemiological studies and studies on this problem in the past 50 years, the World Health Organization has published the finding that smoking increases the risk of infection with M. tuberculosis, increases the risk of progression of infection to active disease and the risk of death. The prevalence of tuberculosis is higher in smokers and former smokers than in nonsmokers. The risk of tuberculosis depends on the number of cigarettes smoked and length of period the person has been a smoker. Passive smoking accelerates the development of active tuberculosis. in children who live with persons suffering from active tuberculosis, Conclusion. Given the multiple consequences of the association between smoking and tuberculosis, prevention of smoking may be an important measure in the control of tuberculosis.

  3. PDH regulation in skeletal muscle

    DEFF Research Database (Denmark)

    Kiilerich, Kristian

    Pyruvate dehydrogenase (PDH) decarboxylates pyruvate into acetyl-CoA and links glycolysis with the Krebs cycle. Because PDH is the only step where carbohydrate-derived substrate can enter the mitochondria and become completely oxidized, PDH activity can potentially determine if glycogen / glucose...... is oxidized completely, or whether pyruvate is converted to lactate. Activity of PDH in the active form (PDHa) is overall determined by the degree of PDH-E1? phosphorylation, where PDH-E1? dephosphorylation activates PDH, while PDH-E1? phosphorylation inactivates PDH. The PDH-E1? phosphorylation state...... in mouse skeletal muscle at rest and in response to fasting and during recovery from exercise.

    Full Text Available A 19-year-old Vietnamese lady was diagnosed with culture positive, left upper lobe pulmonary tuberculosis for which medical treatment was initiated. Four months into treatment, she developed a 'rubber-band-like' stretching sensation in her left chest with wheezing and shortness of breath. Decreased respiratory excursion over the left lung was present on physical-examination. Chest-Xray revealed left-upper-lobe collapse with leftward deviation of the trachea and mediastinum. CT thorax revealed a long segment of stenosis in the left mainstem bronchus. FEV1 was 1.26 L (45% predicted, FVC 1.53 L (49% predicted, FEV1/FVC 82% (95% predicted indicating airway limitation. Ventilation-perfusion scan noted 9.8% ventilation to the left lung and 92.8% to the right lung and 7.6% perfusion to the left lung and 92.4% to the right lung. Bronchoscopy was notable for pin point stenosis of the left mainstem bronchus beyond which was inflamed mucosa and abnormal cartilage rings in the left upper and middle lobe bronchi. Nine months of medical therapy for tuberculosis along with oral steroid taper was completed successfully; however the patient has required six serial bronchscopies with dilatations without stent placement at four to six week intervals due to partial restenosis, with the last bronchoscopy at four months after completion of tuberculosis therapy.

    Full Text Available Abstract Background Tuberculosis (TB remains a major cause of mortality in developing countries, and in these countries diabetes prevalence is increasing rapidly. Diabetes increases the risk of TB. Our aim was to assess the potential impact of diabetes as a risk factor for incident pulmonary tuberculosis, using India as an example. Methods We constructed an epidemiological model using data on tuberculosis incidence, diabetes prevalence, population structure, and relative risk of tuberculosis associated with diabetes. We evaluated the contribution made by diabetes to both tuberculosis incidence, and to the difference between tuberculosis incidence in urban and rural areas. Results In India in 2000 there were an estimated 20.7 million adults with diabetes, and 900,000 incident adult cases of pulmonary tuberculosis. Our calculations suggest that diabetes accounts for 14.8% (uncertainty range 7.1% to 23.8% of pulmonary tuberculosis and 20.2% (8.3% to 41.9% of smear-positive (i.e. infectious tuberculosis. We estimate that the increased diabetes prevalence in urban areas is associated with a 15.2% greater smear-positive tuberculosis incidence in urban than rural areas – over a fifth of the estimated total difference. Conclusion Diabetes makes a substantial contribution to the burden of incident tuberculosis in India, and the association is particularly strong for the infectious form of tuberculosis. The current diabetes epidemic may lead to a resurgence of tuberculosis in endemic regions, especially in urban areas. This potentially carries a risk of global spread with serious implications for tuberculosis control and the achievement of the United Nations Millennium Development Goals.

  7. SPECT/CT diagnostics for skeletal infections

    International Nuclear Information System (INIS)

    Skeletal infections are often a diagnostic and clinical challenge. Nuclear imaging modalities used in the diagnostic workup of acute and chronic skeletal infections include three-phase bone scintigraphy and scintigraphy with labelled leucocytes. The introduction of hybrid technologies, such as single photon emission computed tomography/computed tomography (SPECT/CT) has dramatically changed nuclear medical imaging of infections. In general SPECT/CT leads to a considerably more accurate diagnosis than planar or SPECT imaging. Given the integrated acquisition of metabolic, functional and morphological information, SPECT/CT has increased in particular the specificity of three-phase skeletal scanning and scintigraphy with labeled leucocytes.

    2014-01-01

    Full Text Available Tuberculosis (TB in renal transplant recipients presents important diagnostic difficulties because of the greater incidence of extra-pulmonary involvement, negative sputum smear results despite active disease and its atypical presentation, specifically reactivation of the latent form. BKV nephropathy was first reported in 1995, coinciding with the widespread use of immunosuppressive drugs, which can complicate the cores of 1-10% of renal transplant recipients. It is also not uncommon to find the existence of bacterial or fungal infections in the presence of an immuno-modulating virus like cytomegalovirus infection. Herewith, we describe a 67-year-old Saudi male who presented with deterioration of renal function and fever of unknown origin and was documented to have polyoma virus nephropathy and disseminated TB. To the best of our knowledge, this is the first report of such an association in the literature.

    The resurgence of tuberculosis in the 1990s and the emergence of drug-resistant tuberculosis in the first decade of the 21st century increased the importance of epidemiological models for the disease. Due to slow progression of tuberculosis, the transmission dynamics and its long-term effects can often be better observed and predicted using simulations of epidemiological models. This study provides a review of earlier study on modeling different aspects of tuberculosis dynamics. The models simulate tuberculosis transmission dynamics, treatment, drug resistance, control strategies for increasing compliance to treatment, HIV/TB co-infection, and patient groups. The models are based on various mathematical systems, such as systems of ordinary differential equations, simulation models, and Markov Chain Monte Carlo methods. The inferences from the models are justified by case studies and statistical analysis of TB patient datasets. PMID:22387570

    2009-01-01

    Solitary pancreatic involvement of tuberculosis is rare,especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms.Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques.However, they are composed of a variety of neoplasms with a wide range of malignant potential,and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms. Non-surgical diagnosis of pancreatic tuberculosis is inconclusive and continues to be a challenge in many cases. If so,then laparotomy should be employed to establish the diagnosis. Therefore, pancreatic tuberculosis should be kept in mind during the differential diagnosis of solitary cystic masses in the pancreas. We report a patient who had solitary pancreatic tuberculosis masquerading as pancreatic serous cystadenoma.

    Hemophagocytic syndrome is due to the activation and nonmalignant proliferation of macrophages and T lymphocytes. The purpose of this report is to describe a 25-year-old man who presented with fever, coughing, and weight loss over the past month. Laboratory findings demonstrated pancytopenia, hyperferritinemia, and cytolysis. The myelogram showed a hemophagocytic syndrome, and tuberculosis bacilli were found in the sputum. Chest radiography and thoracic computed tomography depicted a cavitary lesion suggestive of pulmonary tuberculosis. Treatment of tuberculosis alone, without an immunosuppressant agent, was effective and led to improvement. In a country where tuberculosis is highly endemic, hemophagocytic syndrome should be considered in the differential diagnosis of patients with active tuberculosis complicated by pancytopenia.

  1. Mathematical Models of Tuberculosis Reactivation and Relapse

    Directory of Open Access Journals (Sweden)

    Robert Steven Wallis

    2016-05-01

    Full Text Available The natural history of human infection with Mycobacterium tuberculosis (Mtb is highly variable, as is the response to treatment of active tuberculosis. There is presently no direct means to identify individuals in whom Mtb infection has been eradicated, whether by a bactericidal immune response or sterilizing antimicrobial chemotherapy. Mathematical models can assist in such circumstances by measuring or predicting events that cannot be directly observed. The 3 models discussed in this review illustrate instances in which mathematical models were used to identify individuals with innate resistance to Mtb infection, determine the etiology of tuberculosis in patients treated with tumor necrosis factor antagonists, and predict the risk of relapse in persons undergoing tuberculosis treatment. These examples illustrate the power of various types of mathematic models to increase knowledge and thereby inform interventions in the present global tuberculosis epidemic.

    Tuberculosis is a major cause of morbidity and mortality worldwide. It is a chronic granulomatous disease that can affect any part of the body, including the oral cavity. Oral lesions of tuberculosis, though uncommon, are seen in both the primary and secondary stages of the disease. This article presents a case of tuberculosis of the buccal mucosa, manifesting as non-healing, non-painful ulcer. The diagnosis was confirmed based on histopathology, sputum examination and immunological investigation. The patient underwent anti-tuberculosis therapy and her oral and systemic conditions improved rapidly. Although oral manifestations of tuberculosis are rare, clinicians should include them in the differential diagnosis of various types of oral ulcers. An early diagnosis with prompt treatment can prevent complications and potential contaminations.

  3. CT and MR findings of genitourinary tuberculosis

    International Nuclear Information System (INIS)

    Genitourinary tuberculosis is a disease spread hematogenously from a small tuberculous abscess of the lung. The renal cortex is initially involved, and multiple granulomas form. Ultimately the cortex may cavitate and communicate with the collecting system, allowing downward extension of the infection and subsequent focal caliectasis with infundibular stenosis, ureteral fibrosis, and calcifications of urinary tract organs. The female genitourinary organ is also infected by the hematogenous spread of tuberculosis, the most common lesion being hydrosalpynx with salpingitis. The clinical and radiologic features of genitourinary tuberculosis may mimic other acute abdominal diseases, and the diagnosis of tuberculosis remains difficult. This report describes the ways in which computed tomography and magnetic resonance imaging are valuable aids in the recognition and diagnosis of genitourinary tuberculosis. (author)

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.

    2010-01-01

    Full Text Available Insulin resistance in skeletal muscle is manifested by decreased insulin-stimulated glucose uptake and results from impaired insulin signaling and multiple post-receptor intracellular defects including impaired glucose transport, glucose phosphorylation, and reduced glucose oxidation and glycogen synthesis. Insulin resistance is a core defect in type 2 diabetes, it is also associated with obesity and the metabolic syndrome. Dysregulation of fatty acid metabolism plays a pivotal role in the pathogenesis of insulin resistance in skeletal muscle. Recent studies have reported a mitochondrial defect in oxidative phosphorylation in skeletal muscle in variety of insulin resistant states. In this review, we summarize the cellular and molecular defects that contribute to the development of insulin resistance in skeletal muscle.

    2015-11-01

    Inflammation is an important contributor to the pathology of diseases implicated in skeletal muscle dysfunction. A number of diseases and disorders including inflammatory myopathies and Chronic Obstructive Pulmonary Disorder (COPD) are characterized by chronic inflammation or elevation of the inflammatory mediators. While these disease states exhibit different pathologies, all have in common the loss of skeletal muscle mass and a deregulated skeletal muscle physiology. Pro-inflammatory cytokines are key contributors to chronic inflammation found in many of these diseases. This section of the review focuses on some of the known inflammatory disorders like COPD, Rheumatoid Arthritis (RA) and inflammatory myopathies that display skeletal muscle atrophy and also provides the reader an overview of the mediators of inflammation, their signaling pathways, and mechanisms of action. This article is part of a Special Issue entitled "Muscle Bone Interactions".

    Science.gov (United States)

    Wernig, A

    2003-07-01

    The organotypic stem cell of skeletal muscle has previously been known as satellite cell. They allow muscle fiber growth during ontogenesis, enable fiber hypertrophy and are responsible for the very efficient repair of muscle fibers. This efficient apparatus is to some degree counterbalanced by an enormous use of the satellite cell pool: fiber atrophy probably is accompanied by loss of myonuclei such that every reversal of atrophy is bound to use new myonuclei i.e. satellite cells. How often in life does this occur? Hard to say. Moreover, the potent repair capacity is challenged by an unexpected vulnerability of skeletal muscle fibers: Passive stretching of contracted muscles may cause multiple "microdamage," disruption of contractile elements or tiny areas of true necrosis (focal necrosis). How often does this happen? Well, for many of us at least once per year when we go up and down mountains during vacation time, followed by sour muscles. Others may decide to change his/her (locomotor) behaviour by severe onset of jogging; it may happen that they suffer kidney failure on Monday due to muscle microdamage and the transfer of myoproteins into the serum over weekend. Also 20 minutes of stepping up and down something like a chair will do: There is a remarkable increase in kreatin kinase and other muscle derived proteins which lasts for days and is bound to reflect some muscle damage. How about sportsmen and worker who repeatedly use their muscles in such a way? We don't have answers yet to most of these questions, but considerable amount of information has been collected over the last years both in animal and--less--in human. What is common in all cases of growth and repair is the proliferation of the satellite cells and their consequent incorporation and fusion with the parent fiber. This way focal damage is repaired often without visible reminders. We would run out of satellite cells were they not stem cells: After division one daughter remains a satellite cell

    Increased skeletal muscle capillarization is associated with improved glucose tolerance and insulin sensitivity. However, a possible causal relationship has not previously been identified. Therefore, we investigated whether increased skeletal muscle capillarization increases insulin sensitivity. Skeletal muscle-specific angiogenesis was induced by adding the α1-adrenergic receptor antagonist prazosin to the drinking water of Sprague-Dawley rats (n = 33), whereas 34 rats served as controls. Insulin sensitivity was measured ≥40 h after termination of the 3-wk prazosin treatment, which ensured that prazosin was cleared from the blood stream. Whole body insulin sensitivity was measured in conscious, unrestrained rats by hyperinsulinemic euglycemic clamp. Tissue-specific insulin sensitivity was assessed by administration of 2-deoxy-[(3)H]glucose during the plateau phase of the clamp. Whole body insulin sensitivity increased by ∼24%, and insulin-stimulated skeletal muscle 2-deoxy-[(3)H]glucose disposal increased by ∼30% concomitant with an ∼20% increase in skeletal muscle capillarization. Adipose tissue insulin sensitivity was not affected by the treatment. Insulin-stimulated muscle glucose uptake was enhanced independent of improvements in skeletal muscle insulin signaling to glucose uptake and glycogen synthesis, suggesting that the improvement in insulin-stimulated muscle glucose uptake could be due to improved diffusion conditions for glucose in the muscle. The prazosin treatment did not affect the rats on any other parameters measured. We conclude that an increase in skeletal muscle capillarization is associated with increased insulin sensitivity. These data point toward the importance of increasing skeletal muscle capillarization for prevention or treatment of type 2 diabetes. PMID:25352432

    2016-09-01

    Skeletal muscles comprise the largest organ system in the body and play an essential role in body movement, breathing, and glucose homeostasis. Skeletal muscle is also an important endocrine organ that contributes to the health of numerous body organs. Therefore, maintaining healthy skeletal muscles is important to support overall health of the body. Prolonged periods of muscle inactivity (e.g., bed rest or limb immobilization) or chronic inflammatory diseases (i.e., cancer, kidney failure, etc.) result in skeletal muscle atrophy. An excessive loss of muscle mass is associated with a poor prognosis in several diseases and significant muscle weakness impairs the quality of life. The skeletal muscle atrophy that occurs in response to inflammatory diseases or prolonged inactivity is often associated with both oxidative and nitrosative stress. In this report, we critically review the experimental evidence that provides support for a causative link between oxidants and muscle atrophy. More specifically, this review will debate the sources of oxidant production in skeletal muscle undergoing atrophy as well as provide a detailed discussion on how reactive oxygen species and reactive nitrogen species modulate the signaling pathways that regulate both protein synthesis and protein breakdown.

    Full Text Available Introduction. Cat scratch disease (CSD is an acute infectious disease with benign course caused by the bacteria Bartonella henselae. Clinically, it is usually manifested as regional lymphadenopathy and mild infective syndrome. Rare forms of the disease which usually occur in immunocompromised presons are: encephalitis, transverse myelitis, neuroretinitis, granulomatosus conjunctivitis, arthritis, hepatitis etc. Case report. We presented an atypical form of cat scratch disease in a young immunocompetent female person. The disease was manifested with prolonged fever, rash, purulent lymphadenitis and hepatitis. The diagnosis was based on characteristic patohystological finding and exclusion of the other causes of lymphadenopathy. The patient was treated by antibiotics for a few weeks, with surgical incision and drainage of the purulent lymphadenitis. Conclusion. Atypical forms of CSD could be an important differential-diagnostic problem, especially if there is no opportunity for serological confirmation of the disease.

    The origin of chemically peculiar stars remains enigmatic, especially regarding their frequency among their "normal" peers. In addition to magnetic fields and rotation, multiplicity may shed light on the question. We mention the main surveys of the three kinds performed so far of intermediate mass stars, either normal or chemically peculiar, magnetic or not: imaging, spectroscopic, and photometric. We also consider the mulitiplicity of red giant stars, since many of them are descendants of A-type stars, through Mermilliod's radial velocity monitoring of open cluster members. We briefly review the orbital properties of binary systems hosting chemically peculiar stars. Some specific objects of special interest are mentioned as deserving further study. Finally, we recall that some binary systems composed of A-type stars are progenitors of Type Ia supernovae, and evoke the potentialities of future surveys like Gaia.

    Full Text Available We describe a case of papillated Bowen disease (PBD, associated with a clear cell atypical fibroxanthoma (CCAFXA. The epidermal lesion showed a bowenoid papillomatous growth pattern with histologic features suggestive of infection by human papilloma virus (HPV. In the dermis a neoplasm made up by spindled or polygonal cells with wide clear cytoplasm and moderate nuclear pleomorphism was found. Immunohistochemical characteristics of these two lesions were clearly different. The atypical cells of the intraepidermal proliferation were positive for AE1-AE3 anticytokeratin antibody, EMA, p16, p53 and p63. The dermal tumor was positive for vimentin, CD10, CD68, CD99, alpha-1-antitrypsin and c-kit. Histological features and immunohistochemical profile of the dermal tumor corresponded to a CCAFXA, a very uncommon neoplasm of which only 10 cases have been reported. In situ hybridization for numerous types of HPVs was negative in both lesions.

    Full Text Available Study of 18 cases of post-operative CS wound infection due to Atypical Mycobacterium (M. chelonae were found in a single hospital over a six-month period. Though the contaminating source could not be identified, remedial control measures taken includes changing all the operative equipment, autoclave machine, air conditioners, exhaust fans of OT, linen and mattresses and solutions like betadine, savlon, spirit and also suture material replaced with new ones. Antibiotic protocols are changed and daily cleaning of OT with cetrimide solution and daily fumigation for one month. No further Atypical MB infective episode have occurred in the one and a half year since the study. Awareness of this ubiquitous opportunistic organism that is not easily eradicated from the hospital environment and strong suspicion of chronic post-operative wound infection, careful surveillance, detailed attention to disinfectant methods of medical devices and appropriate control measures are essential to prevent potential outbreaks.

    2016-01-01

    Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions of the cool plasma and magnetism in `atypical' prominences, namely when the measured inclination of the magnetic field departs, to some extent, from the predominantly horizontal field found in `typical' prominences. What is the role of the magnetic field in these prominence types? Are plasma dynamics more important in these cases than the magnetic support? We focus our study on three types of `atypical' prominences (tornadoes, bubbles and jet-like prominence eruptions) that have all been observed by THEMIS in the He I D_3 line, from which the Stokes parameters can be derived. The magnetic field strength, inclination and azimuth in each pixel are obtained by using the Principal Component Analysis inversion method on a model of single scattering in the presence of the Hanle effect. The magnetic field in tornadoes is found to be more ...

    Meningiomas are uncommon in children. When they occur, they are frequently associated with neurofibromatosis type 2. Childhood meningiomas are generally large and commonly associated with cyst formation and an unusual location. Perineural tumor spread, occasionally associated with head and neck malignancies, is very rare in meningiomas. We present the MR findings of an atypical meningioma with perineural spread in a 4.5-year-old girl. (orig.)

    2016-05-01

    The histologic features and outcome of 58 cases of epithelioid schwannoma were studied to determine the significance of atypical histologic features. Cases were retrieved from personal consultation files from 1999 to 2013. Patients (31 male and 26 female patients) ranged in age from 14 to 80 years (median, 38 y). Two patients had schwannomatosis 1. Tumors developed in the dermis/subcutis (n=56) or muscle (n=2) of the upper extremity (34.5%), lower extremity (34.5%), thorax/abdomen/back (18%), and less common anatomic locations including the scalp, neck, lip, and breast. They ranged in size from 0.25 to 4.5 cm (median, 2.0 cm). Typically circumscribed and surrounded by a perineurium, they comprised single or small groups of epithelioid schwann cells with a moderate amphophilic cytoplasm and occasional nuclear pseudoinclusions. Stroma varied from myxoid to hyalinized, often with thick-walled vessels (55 cases). Mitotic rate ranged from 0 to 9 mitoses/10 high-power field (HPF) (2.37 mm) in the most active areas (mean, 2 to 3 mitoses/10 HPFs). Thirteen cases (22%) were "atypical," defined by a high mitotic rate (≥3 mitoses per 10 HPFs) and nuclear size variation (≥3:1). All (56/56) expressed S100 protein; type IV collagen invested groups or individual cells (16/17). Melanoma markers were negative, except for melan A (1 case). Follow-up in 39 patients (median, 78 mo; range, 6 to 174 mo) indicated that 31 (79%) were alive without disease (including 9/13 atypical cases; median, 78 mo), 7 (18%) were alive with unknown status, and 1 patient had died of unrelated causes. One tumor recurred, but none metastasized. Epithelioid schwannomas, even those with atypical features, are benign and do not constitute a histologic continuum with epithelioid malignant peripheral nerve sheath tumors, which typically occur in deep soft tissues and have more anaplastic features.

    The sociocommunicative impairments that define autism spectrum disorder (ASD) are not present at birth but emerge gradually over the first two years of life. In typical development, basic attentional processes may provide a critical foundation for sociocommunicative abilities. Therefore early attentional dysfunction in ASD may result in atypical development of social communication. Prior research has demonstrated that persons with ASD exhibit early and lifelong impairments in attention. The p...

    We describe an atypical MRI appearance of multiple sclerosis (MS). Lesions characterized on T2-weighted images by a well-defined rim of increased signal intensity and a concentric region of higher signal intensity were seen in 6 of 132 patients with MS. On T1-weighted images these lesions were evident as regions of low signal intensity, often with a rim of contrast enhancement or increased signal intensity. These appearances tended to be shown by new, evolving lesions. (orig.)

    Full Text Available A 54-year-old woman with a past history of silicone augmentation mammoplasty was admitted with fever and dyspnea with diffuse interstitial shadows on computed tomography (CT. Although radiological findings were atypical, we diagnosed sarcoidosis by laboratory, microbiological, and bronchoalveolar lavage fluid analysis. Corticosteroids ameliorated the condition, but she had recurrent of fever and CT revealed miliary nodules while interstitial shadows disappeared. Liver biopsy showed that noncaseating granuloma and Ziehl-Neelsen stain was positive. We diagnosed miliary tuberculosis which developed during corticosteroid therapy. Antituberculotic therapy resulted in favorable outcome. Possibility exists that onset of sarcoidosis was induced by mammoplasty, namely, human adjuvant disease.

  19. Elevated rates of atypical handedness in paedophilia: Theory and implications

    2014-01-01

    Multiple factors determine handedness including genetics, prenatal stress and post-natal environmental conditions. Atypical handedness, whether manifest as increased sinistrality or decreased strength of lateral preference, has been noted in a wide variety of populations with neuropathology. Those with atypical sexual preferences, specifically paedophilia, also manifest reduced rates of right-handedness. This paper uses the largest sample of phallometrically assessed men to date to establish the pattern of atypical handedness in paedophilia. Specifically, whereas prior research has largely characterized participants dichotomously as right-handed or non-right-handed and/or used self-report of writing hand, this paper expands upon such reports by using the Edinburgh Handedness Inventory's laterality quotient. Participants' handedness and phallometrically assessed sexual preference were analyzed both as continuous and categorical variables, and the responses of those scoring in the range of ambiguous-handedness were evaluated to ascertain whether they were ambiguously handed or more accurately described as mixed-handed. Results indicated those producing scores in the range of ambiguous-handedness demonstrated response patterns consistent with ambiguous-handedness, rather than mixed-handedness. Paedophiles demonstrated high rates of non-right-handedness primarily manifested as sinistrality, whereas those who had a sexual preference for pubescent children evidenced increased ambiguous-handedness. Results support a view of ambiguous-handedness as less pathological than previously hypothesized, and of a neurodevelopmental origin of paraphilic sexual preferences. PMID:24666135

    Full Text Available Abstract Background To report atypical features on Spectral domain optical coherence tomography (SD-OCT in a case of non-familial pure adult nanophthalmos. Case presentation A 39 year old male hyperope was found to have biometric and fundus findings typical of nanophthalmos. The additional atypical features included serous pigment epithelial detachment (PED in right eye and a cuff of subretinal fluid with underlying yellow deposits along superotemporal arcade in the left eye. Fundus flourescein angiogram showed hyperfluorescence due to window defect, dye pooling due to serous PED in right eye and leak superior to disc in right eye and superotemporally in left eye. Cirrus-SD OCT horizontal line scan passing through the fovea showed extensive inner limiting membrane corrugations causing distorted foveal contour in both eyes. A large juxtafoveal serous PED and a small extrafoval PED were seen with folds in the retinal pigment epithelium (RPE-choriocapillary layer in the right eye. Conclusion Structural disruptions in the RPE-choriocapillary complex in the form of folds or juxtafoveal serous PED and RPE folds can be atypical features of nanophthalmic macula better discerned on high resolution OCT.

    Frontotemporal dementia (FTD) is a debilitating disease that is well described in the "Diagnostic and statistical manual of mental disorders, fifth edition (DSM-5)", and typically presents with memory impairment, progressive decline in cortical functioning, and behavioral changes. Age of onset is generally in the late fifties, and usually the first presentation involves a change in behavior and emotional blunting. Treatment of FTD involves management of any neurobehavioral symptoms while trials of atypical antipsychotics are ongoing but suggest some efficacy. We present a case of a patient who first presented with severe paranoid personality traits and frank persecutory delusions. This atypical presentation of our patient first led to her incorrect diagnosis of a psychotic disorder and paranoid personality disorder. As a result of this diagnosis, she was treated unsuccessfully. A subsequent magnetic resonance imaging (MRI) then showed atrophy of frontal and temporal lobes bilaterally (left more prominent than right) which confirmed the diagnosis of FTD. The importance of this case involves the atypical presentation of paranoia and delusions, and our patient's incorrect diagnosis based on her clinical presentation led to a trial of unsuccessful treatment. Only after performing an MRI, which showed atrophy, was the patient appropriately treated and deemed medically stable. This case report illustrates the importance of considering a rare presentation of frontotemporal lobe dementia with patients who are in the typical age range and present with paranoia and delusions.

Reproducible results could be obtained without filtering the bacterial suspension, provided that the organisms were grown in liquid 7H9 medium with 0.05% polysorbate 80 and homogenized prior to the study. Drugs that block protein synthesis were found to have lower minimal inhibitory concentrations with the radiometric method when compared to the conventional agar dilution method. The mean generation time obtained for M. bovis and different strains of M. tuberculosis with various substrates was 9 ± 1 hours.

    The results of post-mortem examinations of 90 warthog (Phacochoerus aethiopicus) conducted in the Ruwenzori National Park, Uganda during a survey of tuberculous infection in wildlife are described. Nine per cent of warthog were found to show gross lesions on autopsy and of these organisms which could by typed, Mycobacterium bovis was isolated in 2 of 6 cases and 5 atypical mycobacterial strains were isolated from the remaining 4. The distribution and character of the lesions is described and it is concluded that the route of infection in the warthog is alimentary. A mycobacterial survey of 8 other species of mammals, 7 species of birds, 5 species of fish and 1 species of amphibian is described. None of the mammals (except possibly 1 elephant), birds, fish or amphibia is described. None of the mammals (except possibly 1 elephant), birds, fish or amphibia was found to be infected with M. bovis but several individuals were found to harbour atypical, probably saprophytic, mycobacterial types. The origin of tuberculosis in buffalo and warthog in the Ruwenzori National Park is discussed and is concluded to have been previous contact with domestic cattle. PMID:7123664

    South Africa has one of the worst tuberculosis burdens in the world. Several ecological forces have contributed to this, including high HIV prevalence; failing TB control strategies; crowded, poorly ventilated indoor environments-including the complex web of political and economic interests which produce them; the development of racial capitalism; and mining and migration. In the following study, we measure CO2 levels in public transport to investigate the role extended commutes from peri-urban settlements to urban sites of work-a direct result of forced removals-potentially play in propagating the TB epidemic in Cape Town, South Africa.

    Tuberculosis control in big cities should be focused on preventing defaulting from treatment, and the prevention of the emergence of multi-drug resistant tuberculosis, and the improvement of treatment success rate. Since it is needed to organize continued case management system starting from hospitalization, discharge, management of regular drug taking at outpatient clinics and final cure, close collaboration should be made between hospital nurses and public health nurses. For this purpose, there should be no difference about the understanding on tuberculosis control between clinical and public health nurses. This research was aimed to examine "How much interest and recognition do hospital nurses have about tuberculosis control." The Aichi Nursing Association cooperated with this research. The results showed that 60% of tuberculosis ward nurses were more than forty years old, and they have served more than ten years in TB word. The levels of understanding on tuberculosis among nurses working in tuberculosis hospitals were much higher than those in general hospitals. However, it is necessary to organize a collaboration system between hospitals and public health center to improve TB case management.

    Abstract Population-based studies of the incidence of tuberculosis in cancer patients according to the type of cancer are limited. We investigated the cancer-specific incidence of tuberculosis in a nationwide population-based cohort in a country with an intermediate burden of tuberculosis. We used mandatory National Health Insurance claims data to construct a cancer cohort of adults (aged 20–99 years) with newly diagnosed malignancies other than lung cancer, from January 2008 to December 2012. Patients who developed tuberculosis in this period were identified in the cancer cohort and the general population. Standardized incidence ratios (SIRs) of tuberculosis in the cancer cohort according to type of cancer and time after cancer diagnosis were calculated by comparing the observed incidence rates with those inferred from the age- and gender-specific incidence rates in the general population. A total of 855,382 cancer patients and 1589,876 person-years (py) were observed. A total of 5745 patients developed tuberculosis; the mean incidence rate was 361.3 per 100,000 py, and the SIR was 2.22 (95% confidence interval [CI], 2.17–2.27). The incidence rate was highest for hematologic malignancy and lowest for thyroid cancer. It was also highest as 650.1 per 100,000 py, with SIR of 3.70 (CI, 3.57–3.83) for the first 6 months after diagnosis of malignancy and then declined. However, it still remained higher than that of the general population after 24 months (SIR = 1.43, CI, 1.36–1.51). The incidence of tuberculosis increases after diagnosis in patients with malignancies. The risk of tuberculosis differs according to the type of cancer and remains elevated even 24 months after cancer diagnosis. Tuberculosis should be considered an important comorbidity in patients with malignancies. PMID:27661041

    International Nuclear Information System (INIS)

    Objective: To determine the frequency and association of Vitamin D deficiency in patients with tuberculosis. Study Design: Case control study. Place and Duration of Study: Medical Department, Combined Military Hospital, Kharian, from July 2010 to June 2012. Methodology: One hundred and five outdoor patients of tuberculosis were selected with 255 gender matched controls. Tuberculosis was diagnosed by presence of acid fast bacilli in sputum smears, positive culture for Mycobacterium tuberculosis or demonstration of chronic caseating granulomatous inflammation in tissue specimens. Controls were drawn randomly from general population. Serum 25 hydroxyvitamin D [25 (OH) D3] levels < 25 ng/ml was considered Vitamin D deficiency. The results were analyzed on SPSS version 17. Results: Mean Vitamin D levels were 23.23 A+- 6.81 ng/ml in cases, 29.27 A+- 8.89 ng/ml in controls (p < 0.0001). Vitamin D deficiency was found in 57% of cases and 33% controls (p < 0.0001). Mean Vitamin D levels were significantly lower in females with tuberculosis (20.84 ng/ml) as compared to males (25.03 ng/ml, p = 0.002). Mean BMI in patients of tuberculosis with Vitamin D deficiency were 19.51 A+- 1.77 kg/m2 and in patients with normal Vitamin D were 21.65 A+- 1.79 kg/m2 (p < 0.0001). Mean Vitamin D levels in patients with multi-drug resistant tuberculosis was lower to a mean of 15.41 A+- 4.67 ng/ml (p < 0.0001). Conclusion: There is significant deficiency of Vitamin D in patients with tuberculosis as compared to controls. This deficiency is more pronounced in females, individuals with low BMI, extra pulmonary and MDR tuberculosis. (author)

    Full Text Available There has been reported increased incidence of ovarian tuberculosis in the tropics since the advent of HIV/AIDS disease. We report a case of bilateral ovarian tuberculosis associated with a single right kidney of uncertain origin in an immunocompetent 15-year-old generally healthy-looking girl. Abdominopelvic scan was equivocal about the diagnosis of the lesion as it failed to differentiate it from malignancy. Tuberculin and histopathology were necessary to confirm the diagnosis of ovarian tuberculosis. Antituberculous medical therapy successfully resolved the disease.

  14. Computerized tomography study in peritoneal tuberculosis

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    Tuberculosis of the spleen is not exceptional. The authors report ten cases which occurred with a predominance in young male adults. All patients had at least one other site of tuberculosis without any HIV infection. All patients had focal splenic lesions in the form of scattered hypo-echogenic and hypodense nodules. These nodules had a pseudo-tumor appearance in one case. CT-guided puncture was performed in one case. Splenic tuberculosis is not as rare as is sometimes thought. The CT-guided splenic puncture is now performed routinely and remains the ideal diagnostic approach. (authors). 9 refs., 5 figs

    Full Text Available Multidrug-resistant tuberculosis (MDR-TB is an increasing global problem. The extent and burden of MDR-TB varies significantly from country to country and region to region. Globally, about three per cent of all newly diagnosed patients have MDR-TB and the proportion is higher in patients who had previously received anti-tuberculosis (anti-TB treatment reflecting the failure of programs designed to ensure complete cure of patients with tuberculosis. The management of MDR-TB is a challenge that should be undertaken by experienced clinicians at centers equipped with reliable laboratory services and implementation of DOTS-Plus strategy.

    Full Text Available Tuberculosis is an ancient infectious disease that remains a threat for public health around the world. Although the etiological agent as well as tuberculosis pathogenesis is well known, the molecular mechanisms underlying the host defense to the bacilli remain elusive. In this paper we focus on the innate immunity of this disease reviewing well-established and consensual mechanisms like Mycobacterium tuberculosis interference with phagosome maturation, less consensual mechanism like nitric oxide production, and new mechanisms, such as mycobacteria translocation to the cytosol, autophagy, and apoptosis/necrosis proposed mainly during the last decade.

    Full Text Available Tuberculosis is a disease with myriad presentations and manifestations; it can affect any organ or tissue, excluding only hair and nails. Doctors who are not familiar with extrapulmonary tuberculosis often overlook this disease. Urogenital tuberculosis (UGTB is the second most common form of TB in countries with severe epidemic situation and the third most common form in regions with low incidence of TB. The term “Urogenital tuberculosis” includes kidney tuberculosis; male and female tuberculosis and urinary tract tuberculosis as complication of kidney tuberculosis. We describe rarest case of tuberculosis of a placenta in young woman, suffered from genital tuberculosis, which was overlooked before delivery, as well as typical tubo-ovarian tuberculomas.

  2. Perspectives on tuberculosis in pregnancy

    2015-03-01

    Full Text Available Tuberculosis (TB has been recognized as an important cause of morbidity and mortality in pregnancy for nearly a century, but research and efforts to roll out comprehensive TB screening and treatment in high-risk populations such as those with a high prevalence of HIV or other diseases of poverty, have lagged behind similar efforts to address HIV infection in pregnancy and the prevention of mother-to-child-transmission. Immunological changes during pregnancy make the activation of latent TB infection or de novo infection more likely than among non-pregnant women. TB treatment in pregnancy poses several problems that have been under-researched, such as contraindications to anti-TB and anti-HIV drugs and potential risks to the neonate, which are particularly important with respect to second-line TB treatment. Whilst congenital TB is thought to be rare, data from high HIV burden settings suggest this is not the case. There is a need for more studies screening for TB in neonates and observing outcomes, and testing preventative or curative actions. National tuberculosis control programmes (NTPs should work with antenatal and national HIV programmes in high-burden populations to provide screening at antenatal clinics, or to establish functioning systems whereby pregnant women at high risk can drop in to routine NTP screening stations.

  3. Central nervous system tuberculosis: MRI

    International Nuclear Information System (INIS)

    The MRI findings of 18 proven cases of central nervous system (CNS) tuberculosis were reviewed; 10 patients were seropositive for HIV. All had medical, laboratory, or surgical proof of CNS tuberculosis. Eleven patients had meningitis, of whom two also had arachnoiditis. Five patients had focal intra-axial tuberculomas: four brain masses and one an intramedullary spinal lesion. Two patients had focal extra-axial tuberculomas: one in the pontine cistern, and one in the spine. In all 11 patients with meningitis MRI showed diffuse, thick, meningeal enhancement. All intraparenchymal tuberculomas showed low signal intensity on T2-weighted images and ring or nodular enhancement. The extra-axial tuberculomas had areas isointense or hypointense relative to normal brain and spinal cord on T2-weighted images. Although tuberculous meningitis cannot be differentiated from other meningitides on the basis of MR findings, intraparenchymal tuberculomas show characteristic T2 shortening, not found in most other space-occupying lesions. In the appropriate clinical setting, tuberculoma should be considered. (orig.)

  4. New tuberculosis diagnostics and rollout

    Full Text Available Early detection and effective treatment are crucial for tuberculosis control, but global case detection rates remain low. The diagnosis of paediatric and extrapulmonary disease is problematic and there are, as yet, no rapid screening tests to assist active case finding in the community. Progress has been made in clinic-based detection tools with the introduction of Xpert MTB/RIF, a nucleic acid amplification test that combines sample processing and analysis in a single instrument to provide a diagnostic result and detection of resistance to rifampicin in under 2 h. Enthusiasm for Xpert MTB/RIF has been high and global rollout has been facilitated by donor agencies. However, concerns remain about access and sustainability due to the high cost and infrastructure requirements. Although more sensitive than smear microscopy, early studies suggest the impact of the new test on case detection rates and patient survival has been limited. Alternative technologies are being developed, including non-sputum-based tests to assist the detection of extrapulmonary disease. Evaluation studies are needed to provide evidence of the impact of the new technologies on patient outcomes. This will enable appropriate placement of new diagnostic products in the healthcare system to support the control and eventual eradication of tuberculosis disease.

    Full Text Available Background: There is an increasing incidence of Human immunodeficiency virus (HIV and tuberculosis (TB co-infection. This has led to an increasing number of atypical features on magnetic resonance imaging (MRI. We postulated that the type 4 hypersensitivity response causing granulomatous inflammation may be disrupted by the HIV resulting in less vertebral body destruction. This study compares the MRI features of spinal tuberculosis in HIV positive and negative patients. Materials and Methods: Fifty patients with confirmed spinal tuberculosis, HIV status and available MRI scans at a single institution from 2003-2009 were identified. HIV status was positive in 20 and negative in 30. Females were predominant (34:16. The HIV positive group was younger at 32.4 versus 46 years (P=0.008. Blood parameters (WCC, ESR, Hb, Lymphocyte count were not significantly different between the HIV groups. MRI scans were reviewed by a radiologist who was blinded to the HIV status. Site, extent of disease, body collapse, abscess location and volume, kyphotic deformity and cord signal were reported. Results: There was no difference between the number of vertebral bodies affection with TB involvement, presence of cord signal or incidence of non-contiguous lesions. The HIV negative group had significantly more total vertebral collapse (P=0.036 and greater kyphosis (P=0.002. The HIV positive group had a trend to larger anterior epidural pus collection (P=0.2. Conclusion: HIV negative patients demonstrate greater tuberculous destruction in terms of total percentage body collapse and resultant kyphosis. There is no difference in the incidence of cord signal or presence of non-contiguous lesions. HIV positive patients show a trend to a greater epidural abscess volume. This difference may be explained by the reduced autoimmune response of the type 4 hypersensitivity reaction caused by the HIV infection.

    Skeletal muscle regeneration efficiency declines with age for both men and women. This decline impacts on functional capabilities in the elderly and limits their ability to engage in regular physical activity and to maintain independence. Aging is associated with a decline in sex hormone production. Therefore, elucidating the effects of sex hormone substitution on skeletal muscle homeostasis and regeneration after injury or disuse is highly relevant for the aging population, where sarcopenia affects more than 30 % of individuals over 60 years of age. While the anabolic effects of androgens are well known, the effects of estrogens on skeletal muscle anabolism have only been uncovered in recent times. Hence, the purpose of this review is to provide a mechanistic insight into the regulation of skeletal muscle regenerative processes by both androgens and estrogens. Animal studies using estrogen receptor (ER) antagonists and receptor subtype selective agonists have revealed that estrogens act through both genomic and non-genomic pathways to reduce leukocyte invasion and increase satellite cell numbers in regenerating skeletal muscle tissue. Although animal studies have been more conclusive than human studies in establishing a role for sex hormones in the attenuation of muscle damage, data from a number of recent well controlled human studies is presented to support the notion that hormonal therapies and exercise induce added positive effects on functional measures and lean tissue mass. Based on the fact that aging human skeletal muscle retains the ability to adapt to exercise with enhanced satellite cell activation, combining sex hormone therapies with exercise may induce additive effects on satellite cell accretion. There is evidence to suggest that there is a 'window of opportunity' after the onset of a hypogonadal state such as menopause, to initiate a hormonal therapy in order to achieve maximal benefits for skeletal muscle health.

    Introduction: In orthodontics, apart from essential diagnostic aids, there are so many soft tissue analyses in which lips are major part of concern. However, lip prints have never been used in orthodontics as diagnostic aid or forensic tool. Therefore, this study was designed to explore the possible association of lip prints with skeletal malocclusion. Materials and Methods: A sample of 114 subjects in the age group of 18-30 years, from North Indian adult population were selected on the basis of skeletal class I, class II and class III malocclusion, each comprising of 38 subjects with equal number of males and females. Lip prints of all the individuals were recorded and digital soft copies of lateral cephalograms were taken. Lip prints were compared between different skeletal malocclusions. Results: It was found that branched lip pattern was most common in North Indian adult population with no sexual dimorphism. The Z-test for proportion showed that the prevalence of vertical lip pattern was significantly higher in subjects having skeletal class III malocclusion. Conclusion: A definite co-relation of vertical lip patterns with skeletal class III malocclusion was revealed. PMID:24255559

    Full Text Available Gastric tuberculosis is a rare presentation of tuberculosis infection. Gastric perforation associated with tuberculosis is exceedingly rare with five previously published cases. We present a case of a male patient that developed presumed gastric tuberculosis secondary to pulmonary tuberculosis infection. He subsequently developed gastric perforation and sepsis, for which he was treated both surgically and medically. Despite ongoing antituberculosis treatment, the patient's condition worsened and the patient died secondary to multiorgan failure. This case highlights gastric perforation as a rare but devastating complication of pulmonary tuberculosis.

    Full Text Available The W.H.O. (1982 estimates that the annual risk of infection with tuberculosis in most developing countries is in the order of 3 to 5%. Every year 4-million to 5-million highly infectious cases of tuberculosis occur in those countries, according to the WHO Technical Report No. 671. This report also states that case finding and chemotherapy, combined as one entity, must be considered to be the most powerful weapon in tuberculosis control. Since case finding in those countries depends principally on the examination of patients presenting with relevant symptoms to a health facility, it is recommended that all staff at such facilities should be properly trained and motivated to identify potential tuberculosis patients.

    Full Text Available Tuberculosis is an important cause of uveitis in our country. India has been declared the country with the highest tuberculosis burden with 25 % of the cases . (1 This is especially true in Andhra Pradesh and Telangana which have a high percentage of affected patients. However , tuberculous uveitis is usually a unilateral presen tation. We report a case of bilateral uveitis of tuberculous origin in a 55 year old woman. She presented with different tuberculous manifestations in the two eyes. While the RE showed non granulomatous uveitis with sclerosing keratitis , the LE showed gran ulomatous uveitis with mutton fat keratic precipitates. Systemic examination revealed an enlarged lymph node which was positive for tuberculosis on biopsy. She was hence diagnosed as extra pulmonary tuberculosis and was treated with ATT regimen. In this pa tient , uveitis was the initial manifestation and resulted in a systemic diagnosis.

    RATIONALE: In the absence of active tuberculosis, a positive tuberculin skin test (TST) or interferon-γ release assay (IGRA) result defines latent infection with Mycobacterium tuberculosis, although test results may vary depending on immunodeficiency. OBJECTIVES: This study compared the performance...... of TST and IGRAs in five different groups of immunocompromised patients, and evaluated their ability to identify those at risk for development of tuberculosis. METHODS: Immunocompromised patients with HIV infection, chronic renal failure, rheumatoid arthritis, solid-organ or stem-cell transplantation......, and healthy control subjects were evaluated head-to-head by the TST, QuantiFERON-TB-Gold in-tube test (ELISA), and T-SPOT.TB test (enzyme-linked immunospot) at 17 centers in 11 European countries. Development of tuberculosis was assessed during follow-up. MEASUREMENTS AND MAIN RESULTS: Frequencies of positive...

In addition, one third of the world's population is latently infected with Mycobacterium tuberculosis (Mtb and up to 10% of infected individuals develop tuberculosis (TB in their lifetime. In this investigation, the incidence of urinary tuberculosis among renal patients was studied. Three hundreds urine samples were processed for detection of Mtb by Ziehl-Neelson (ZN smear examination, Lowenstein Jensen (LJ medium, radiometric BACTEC460 system as well as polymerase chain reaction (PCR and DNA Enzyme Immunoassay (DEIA test.  Out of 300 urine samples, 2 were positive by both  ZN smears and LJ medium with incidence rate of 0.66 %, 3 positive samples by BACTEC460 culture system with incidence of 1%. PCR assay gave more positive results than smear and culture examination (i.e. 8 positive samples with incidence  rate of 2.6%.  The specificities were 25% for both ZN smears and LJ medium, 37.5% for BACTEC460 culture system, and 100% for PCR test, while  sensitivities of all assays were 100%. Thus PCR is a rapid and sensitive method for the early diagnosis of urinary tuberculosis.   Keywords: List of abbreviations:Acid Fast Bacilli (AFB-Base pair (bp-DNA Enzyme Immunoassay (DEIA  -Extrapulmonary Tuberculosis

    2009-01-01

    Animal models for testing different vaccine candidates have been developed since a long time for studying tuberculosis. Mice, guinea pigs and rabbits are animals most frequently used. Each model has its own merits for studying human tuberculosis, and none completely mimics the human disease. Different animal models are being used depending upon the availability of the space, trained manpower as well as other resources. Efforts should continue to develop a vaccine which can replace/outperform the presently available vaccine BCG. PMID:19287053

    Dirks-Naylor, Amie J

    2015-12-15

    Coffee is consumed worldwide with greater than a billion cups of coffee ingested every day. Epidemiological studies have revealed an association of coffee consumption with reduced incidence of a variety of chronic diseases as well as all-cause mortality. Current research has primarily focused on the effects of coffee or its components on various organ systems such as the cardiovascular system, with relatively little attention on skeletal muscle. Summary of current literature suggests that coffee has beneficial effects on skeletal muscle. Coffee has been shown to induce autophagy, improve insulin sensitivity, stimulate glucose uptake, slow the progression of sarcopenia, and promote the regeneration of injured muscle. Much more research is needed to reveal the full scope of benefits that coffee consumption may exert on skeletal muscle structure and function.

We retrospectively studied atypical lymphocytes (AL and atypical lymphocytosis (ALO, defined as AL > 5% of total white blood cells in 1310 uncomplicated malaria patients. In 718 falciparum malaria patients, AL and ALO on day 0 were found in 53.2% and 5.7% of the patients, respectively, with median AL on admission of 1% (range 0%–10%, whereas in 592 vivax malaria patients, AL and ALO on day 0 were found in 55.4% and 9.5% of the patients, respectively, with median AL on admission of 1% (range 0%–14%. After antimalarial treatment, AL and ALO declined in both falciparum and vivax malaria. However, AL and ALO remained in falciparum malaria on days 7, 14, and 21, whereas AL and ALO remained in vivax malaria on days 7, 14, 21, and 28. In both falciparum and vivax malaria patients, there was a positive correlation between AL and total lymphocytes, but a negative correlation between AL and highest fever on admission, white blood cells, and neutrophils, eosinophils, and platelets (P < 0.05. In conclusion, AL or ALO may be found in uncomplicated falciparum and vivax malaria mimicking dengue infection. In tropical countries where both dengue and malaria are endemic, presence of AL or ALO in any acute febrile patients with thrombocytopenia (similar to the findings in dengue malaria could not be excluded. Particularly if the patients have risk of malaria infection, confirmative microscopic examination for malaria should be carried out

    2015-01-01

    By taking the surface chemical reactions as the rate-controlling step, a possible reaction mechanism for ethylene epoxidation to synthesize ethylene oxide over the A-type silver catalyst was developed, while it was assumed that the ep-oxidation reaction would take place between ethylene and the un-dissociated adsorbed oxygen O2a on the solo active sites, while the deep oxidation would occur between ethylene and the dissociated adsorbed oxygen Oa on the adjacent multi-active sites. In order to describe the effect of 1,2-C2H4Cl2 (EDC) inhibitor on the ethylene epoxidation process, the reversible reac-tions between EDC and vinyl chloride (VC) on the active sites of silver catalyst was introduced. According to the assumed mechanism, the hyperbolic macro-kinetic model of ethylene epoxidation over the A-type silver catalyst was established, and the macrokinetic experiments were carried out in an internal-recycle gradientless reactor operating at a pressure of 2.1 MPa and a temperature in the range of 217.8—249.0℃, with the gas composition (molar fraction) consisting of 15.82%—34.65%C2H4, 2.55%—7.80%O2, 0.88%—6.15%CO2, 0.15—2.61μmol/mol of 1,2-C2H4Cl2 and 0.14—1.28μmol/mol of C2H3Cl. By means of the Simplex Optimal Method, the parameters of the macrokinetic models were estimated. Statistical test showed that the macrokinetic models developed for the A-type silver catalyst agree well with the experimental results.

    The aim of the study was to look back on the course of action involving measures of tuberculosis control in Brazil since the end of the 19th century, covering the history of social struggles and pointing out institutions and people that have dedicated themselves to looking for solutions to these issues. The Brazilian response to tuberculosis started in society with the Ligas Contra a Tuberculose (Leagues Against Tuberculosis), promoting scientific advances, such as the BCG vaccination, which begun in 1927. From the public power, the Inspetoria de Profilaxia da TB (TB Prophylaxis Inspection Service - 1920), the Serviço Nacional de Tuberculose (National Service of Tuberculosis - 1940), and the Campanha Nacional Contra a Tuberculose (National Campaign Against Tuberculosis - 1946), coordinated national policies such as chemotherapy, beginning with the discovery of streptomycin in 1944. The emergence of bacterial resistance led to the development of several therapeutic schemes. The Scheme 1 (rifampycin, hydrazide and pyrazinamid), which was the main one in 1979 and is still used nowadays, had a great epidemiological effect. The WHO declared TB a public health emergency in 1993. In response, Brazil developed some strategies; the first one was the Plano Emergencial para Controle da Tuberculose (Emergency Plan for Tuberculosis Control - 1994), prioritizing 230 municipalities. The current prospects are an effective municipalization of actions and their greater integration with the Programas de Agentes Comunitários e Saúde da Família (Humanitarian Agents and Family Health Programs).
