    Full Text Available Lupus miliaris disseminatus faciei also known as acne agminata is a rare disease affecting face in adults. Previously, it was thought to be a tuberculid; and its relation with rosacea is undefined. We report a case who had multiple yellowish brown to erythematous small papular lesions and many pitted atrophic scars on the face of 8 months duration. Investigations for tuberculosis were negative. Histopathology revealed tuberculoid granuloma.

    Full Text Available Lupus miliaris disseminatus faciei (LMDF is a chronic, rare inflammatory dermatosis characterized by yellowish-red papules with a smooth surface especially on the face and around the eyelids. Recently, due to its histological appearance and different involvement areas, the predominated idea is that it is a granulomatous reaction against to the hair follicle destruction and ruptured epidermoid cysts. A 32-year-old female patient admitted to our outpatient clinic because of the acne lesions on her face and hands for 2 months. The patient was diagnosed as LMDF with clinical and histopathologic findings. In addition, biopsy of the papules around the eyelids revealed epidermoid cyst structures associated with the granulomas. On the occasion of this case, we revised LMDF, a dermatosis which still causes different ideas about naming and etiopathogenesis, in the light of the literature; we discussed differential diagnosis and we analyzed the association with epidermoid cysts.

    Full Text Available Lupus miliaris disseminatus faciei is an uncommon disease affecting face. Previously lupus miliaris disseminatus faciei was thought to be a tuberculid; but now it is considered as a granulomatuous variant fo acne rosacea. We report 4 cases; each having lesions on face but in 1 also on body. The cases had erythematous tiny popular lesions of varying chronicity of 4 months to 1 year. Investigations for tuberculosis were negative. Histopathology revealed tuberculoid granuloma. All patients responded to Erythromycin; except 1 required Chloroquine.

    Abstract The aim of this study was to determine the clinical features, and outcome of the patients with miliary tuberculosis (TB). We retrospectively evaluated 263 patients (142 male, 121 female, mean age: 44 years, range: 16–89 years) with miliary TB. Criteria for the diagnosis of miliary TB were at least one of the followings in the presence of clinical presentation suggestive of miliary TB such as prolonged fever, night sweats, anorexia, weight loss: radiologic criterion and pathological criterion and/or microbiological criterion; pathological criterion and/or microbiological criterion. The miliary pattern was seen in 88% of the patients. Predisposing factors were found in 41% of the patients. Most frequent clinical features and laboratory findings were fever (100%), fatigue (91%), anorexia (85%), weight loss (66%), hepatomegaly (20%), splenomegaly (19%), choroid tubercules (8%), anemia (86%), pancytopenia (12%), and accelerated erythrocyte sedimentation rate (89%). Tuberculin skin test was positive in 29% of cases. Fifty percent of the patients met the criteria for fever of unknown origin. Acid-fast bacilli were demonstrated in 41% of patients (81/195), and cultures for Mycobacterium tuberculosis were positive in 51% (148/292) of tested specimens (predominantly sputum, CSF, and bronchial lavage). Blood cultures were positive in 20% (19/97). Granulomas in tissue samples of liver, lung, and bone marrow were present in 100% (21/21), 95% (18/19), and 82% (23/28), respectively. A total of 223 patients (85%) were given a quadruple anti-TB treatment. Forty-four (17%) patients died within 1 year after diagnosis established. Age, serum albumin, presence of military pattern, presence of mental changes, and hemoglobin concentration were found as independent predictors of mortality. Fever resolved within first 21 days in the majority (90%) of the cases. Miliary infiltrates on chest X-ray should raise the possibility of miliary TB especially in countries where TB is

    Full Text Available Tinea faciei, is a facial superficial mycosis. The most frequent etiological agents are Microsporum canis, Trichophyton rubrum and T. tonsurans. It is often overlooked when considering the differential diagnoses of Rosacea. The most well known dermatology textbooks list acne, LE, perioral dermatitis, nasal sarcoidosis, carcinoid syndrom and other conditions but do not mention TF. We describe 3 patients with lesions that clinically appeared to be Rosacea.

    A 32-year-old HIV positive male presents with fevers and a non-productive cough. Initial X-ray and subsequent computerised tomography of the chest shows a bilateral miliary pattern of pulmonary infiltration highly suggestive of disseminated tuberculosis. However subsequent results were consistent with disseminated cryptococcosis, including pulmonary involvement, with cryptococcus identified on transbronchial tissue biopsy, and on blood and cerebrospinal fluid cultures. Imaging features of pulmonary cryptococcosis are generally of well-defined pleural-based nodules and less commonly alveolar infiltrates, lymphadenopathy, pleural effusions or cavitating lesions. Miliary pulmonary infiltrates are an exceptionally rare presentation. PMID:25379393

    Full Text Available Presence of miliary shadows in chest imaging in the appropriate clinical setting is often taken as a marker of miliary tuberculosis. If sputum is negative for acid -fast bacillus, empirical anti-tubercular therapy is given without securing a histological or microbiological diagnosis. We report a young female with human immunodeficiency virus infection who had miliary infiltrates on chest radiography. She was started on empirical anti-tubercular therapy. But an alternate diagnosis was achieved later with invasive sampling and ATT was stopped. This case illustrates the need for physicians to remain alert to diseases which mimic tuberculosis in presentation.

    Tinea faciei is a relatively uncommon dermatophyte infection entailing atypical clinical symptoms, usually misdiagnosed and treated with corticosteroids. The authors describe a case of tinea faciei on the right eyebrow caused by Trichophyton interdigitale. The patient was an 18-year-old girl, who had an inflammatory plaque with a scaly, pustular surface on the right eyebrow and upper eyelid, which had persisted for over 1 month. She was once misdiagnosed as having eczema and was treated using corticosteroid cream. A diagnosis of tinea faciei was made based on direct microscopy and culture. The sequencing of the nuclear ribosomal ITS region and β-tubulin gene of the isolate established its T. interdigitale lineage. The patient was cured by treatment with systemic terbinafine in combination with topical application of 1% naftifine-0.25% ketaconazole cream for 2 weeks. PMID:28099612

    Although, miliary tuberculosis is an unusual cause of severe acute respiratory failure, we describe nine patients with miliary tuberculosis who developed adult respiratory distress syndrome. This complication occurred in seven patients despite treatment with antituberculous drugs. In two patients who developed the syndrome, miliary tuberculosis was diagnosed only at postmortem. The presence of pulmonary hypertension in all cases and disseminated intravascular coagulation in seven cases suggests a possible pathophysiologic relationship with severe pulmonary vascular damage. The high mortality rate (88.8%) was associated with nonpulmonary organ system failure. Miliary tuberculosis should be considered in patients with adult respiratory distress syndrome of unknown etiology, and simple diagnostic procedures such as sputum, bronchial brushing, and gastric examination should be followed by invasive diagnostic procedures to confirm this etiology. Since untreated miliary tuberculosis is usually fatal, early recognition of this disease is of great importance, and specific therapy may play a lifesaving role.

    To evaluate MRI(Magnetic Resonance Imaging) findings of miliary tuberculosis of the brain Six patients with miliary tuberculosis of the brain diagnosed by characteristic clinical or laboratory findings were studied with spin echo MRI before and after contrast enhancement. We retrospectively evaluated MRI findings according to the appearance, distribution, location, and enhancement pattern of the granulomas as well as associated other abnormalities. In six patients, contrast-enhanced MRI of the brain showed numerous punctate, contrast enhancing lesions scattered throughout the brain. Unenhanced MRI failed to demonstrate small granulomas except a few small foci of high signal intensity on T2-weighted images. The shapes of enhancing granulomas were homogeneous nodular enhancement in 86% of cases and small ring enhancement in 14%. 98% of granulomas were smaller than 3-mm and 2% were larger. Although several lesions were located in the basal ganglia, thalamus, and brain stem, the majority were located in the subpial and subarachnoid space. There was no significant difference in distribution of granulomas between the supratentorial and the infratentorial areas. Other associated abnormalities were focal meningitis in five cases and focal cerebritis in one. On chest radiograph, all patients had miliary tuberculosis in the lungs. Contrast-enhanced T1-weighted MR imaging showed numerous round, very small enhancing lesions scattered throughout the brain. The majority of lesions were located in the subpial and subarachnoid space. Contrast-enhanced T1-weighted images are helpful in the detection and diagnosis of miliary disseminated tuberculous granulomas and meningitis.

    Full Text Available Fahad D Alosaimi,1 Feras A Alkharboush,2 Maram H Altuwariqi11Department of Psychiatry, King Saud University, Riyadh, Kingdom of Saudi Arabia; 2College of Medicine, King Saud University, Riyadh, Kingdom of Saudi ArabiaAbstract: Miliary tuberculosis (TB is a serious infection with various presentations that can perplex even the most experienced clinicians. To our knowledge, there is a lack of published reports that link psychiatric symptoms directly with miliary TB (either alone or co-occurring with other medical symptoms. Mental health workers may, therefore, not consider, and consequently miss, this important diagnosis. Here we are reporting a case of cyclical anxiety occurring in a 67-year-old patient. For 3 years prior to admission, the patient failed to respond to multiple courses of different antianxiety medications. The patient required hospital admission as he deteriorated and had a reduced level of consciousness. A chest X-ray revealed bilateral nodules and a magnetic resonance imaging scan showed multiple enhancing tuberculous lesions in the cerebral white matter, brain stem, and cerebellum. A diagnosis of miliary TB was finally made. Several characteristics of this case suggest that the diagnosed anxiety disorder was due to miliary TB. However, we cannot exclude the possibility that generalized anxiety disorder preceded the onset of miliary TB or that both diseases were coincidental. The report serves as a reminder that organic causes for psychiatric symptoms always need to be considered, particularly if they follow an atypical pattern or fail to improve with usual psychiatric medications.Keywords: anxiety disorder, elderly, psychosomatic, case report, Saudi Arabia

    Gout is a systemic disorder characterized by hyperuricemia and recurrent arthritis, most involvement of ankles, midfoot joint and first metatarsophalangeal joint, with monosodium urate crystals deposition in synovial fluid and other tissues. We present a case of 53-year-old male, who had several nontender, white-yellow papules and plaques over his elbows, knees and arms with chalk-like substances and crust on inflammatory base wax and wane in the past 2 years. Upon histopathology examination of the skin lesions, it reported as intradermal urate tophi and miliarial gout was diagnosed. This case highlights the importance of considering unusual cutaneous tophi in the differential diagnosis of deposition disorders.

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

    Full Text Available Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner’s pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and some sarcomas. Although very infrequent, miliary mottling can be seen in primary lung cancers. Herein, we report the case of a 28-year-old female with chest X-ray showing miliary mottling. Thoracic computed tomography (CT features were suggestive of tuberculoma with miliary tuberculosis. CT-guided fine needle aspiration cytology confirmed the diagnosis as lower-lobe, left lung non-small cell carcinoma (adenocarcinoma. It is rare for the non-small cell carcinoma of the lung to present as miliary mottling. The rarity of our case lies in the fact that a young, non-smoking female with miliary mottling was diagnosed with non-small cell carcinoma of the lung.

    Histoplasmosis is a disease caused by inhalation of the fungus Histoplasma capsulatum. In rare cases the disease affects immunocompetent individuals. Disseminated and severe disease is seen in immunocompromised patients. We report a case of a 45 year old immunocompromised patient presenting with weight loss and abdominal pain. Chest x-ray and computerized tomography examinations showed interstitial infiltrate and diffuse micro nodules. The initial diagnosis was miliary tuberculosis. However, the definitive diagnosis of miliary histoplasmosis was made later on. (author)

    2016-01-01

    Background: Erythromelanosis follicularis faciei et colli (EFFC) has always been reported as a rare disorder, and more data are needed to define its etiology and epidemiology. Objectives: To present a descriptive study of this disorder from Kashmir and present a review of literature on the same. Materials and Methods: A cross-sectional, descriptive study was conducted on 14 patients with clinical lesions suggestive of EFFC, presenting to our dermatology outpatient clinic between May 2013 and April 2015. After obtaining informed consent from all patients, the demographic and clinical data were collected and punch biopsies were taken which after being fixed in formalin were stained for hematoxylin and eosin. The study was approved by Institutional Review Board. Results: Age of the patients ranged from 12 to 35 years with a mean age of 24.8 years. Females outnumbered males in a ratio of 1.3:1. Family history was positive in one case, and one patient had unilateral presentation. The classical triad of erythema, pigmentation, and follicular papules were present in 100% patients. Telangiectasias were observed in 28.57% patients only. Classical sites described were involved in all the cases (100%). In addition, lesions were found to involve eyebrows (28.57%), forehead (28.57%), upper lips (14.28%), and pinna (21.42%). Keratosis pilaris was present in all patients (100%); most common sites affected were upper arms and thighs. Two (14.28%) had generalized distribution. Histopathology in all correlated well with clinical findings. Conclusion: EFFC has always been reported as a rare disorder, but we believe that it is not so. The reason could be either lack of awareness of the disease by the patient due to its generally asymptomatic nature or under-recognition by the physicians. Awareness about the disease on part of dermatologist and recognition of clinical presentation is important for correct diagnosis and to help find more effective therapeutic modalities. PMID:27293252

    An 87-year-old woman was admitted because of high fever, progressive dyspnea and abnormal shadows on chest roentgenogram. Laboratory investigation on admission demonstrated a normal white cell count with neutrophilia (4000/microl, 90.5% neutrophils), an erythrocyte sedimentation rate of 10 mm/h and C-reactive protein value of 9.0mg/dl. Roentgenogram and computed tomographic scan of the chest shows bilateral infiltration and diffuse ground glass opacity, indicating acute respiratory distress syndrome (ARDS), but disseminated nodules, indicating miliary tuberculosis, were not found. Blood gas analysis demonstrated severe hypoxemia (PaO2 43.2Torr with 6L/ min oxygen). Based on the diagnosis of acute pneumonia and ARDS, intravenous administration of sivelestat sodium hydrate (100 mg/day), and continuous infusion of hydrocortisone (200 mg/day) were started. PaO2/FiO2 ratio improved but X-ray findings showed no improvement and a blood test revealed pancytopenia. Bone marrow biopsy revealed necrotizing epithelioid granuloma and acid-fast bacilli. A polymerase chain reaction (PCR) test detected Mycobacterium tuberculosis. Mycobacterium tuberculosis was also detected in sputum and urine. Therefore, we diagnosed miliary tuberculosis and transferred the patient to an infectious disease hospital. Miliary tuberculosis complicated with ARDS is relatively rare and the prognosis is extremely poor. Miliary tuberculosis should be kept in mind as a cause of ARDS.

    Chronic hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. In the last 5 years, treatment for HCV infection has experienced a marked development. In 2014, the use of ledipasvir/sofosbuvir with or without concomitant weight-based ribavirin was approved with a very significant increase in the sustained virological response. However, new side effects have been associated. We report the first case of an HCV infected patient treated for 12 wk with the combination of sofosbuvir/ledipasvir plus ribavirin who developed a miliary tuberculosis (TB) infection while on therapy. The patient was a 65-year-old woman, who referred malaise, asthenia, hyporexia, 7 kg weight loss, productive cough, evening fever and night sweats, right after finishing the treatment. The chest computed tomography-scan revealed a superior mediastinal widening secondary to numerous lymphadenopathies with extensive necrosis and bilateral diffuse lung miliary pattern with little subsequent bilateral pleural effusion, highly suggestive of lymph node tuberculosis with lung miliary spread. A bronchoscopy was performed and bronchial suction showed more than 50 acid-alcohol resistant bacillus per line. A Mycobacterium tuberculosis DNA was detected in blood by polymerase chain reaction, which confirmed the diagnosis of miliary tuberculosis. Some cases of TB infection have been identified with α-interferon-based therapy and with the triple therapy of pegylated interferon, ribavirin and boceprevir or telaprevir. However, significant infection has not been reported with sofosbuvir/ledipasvir plus ribavirin. We believe that the case is relevant to increase awareness of opportunistic infections and particularly TB infection. Although the international guidelines offer no recommendation regarding TB screening, we wonder whether it would be advisable to screen for opportunistic infections prior to the introduction of HCV therapy.

    Miliary dissemination is a rare form of brain metastasis. The clinical and pathologic features of this form are unclear. We report a 66-year-old man with miliary brain metastases from adenocarcinoma of the lung, describing MRI and neuropathologic findings in the context of previously reported cases. Initial disorientation progressed to an apallic state within 6 months. Although, CT with administration of contrast agent failed to demonstrate any lesions, MRI with Gd-DTPA administration showed multiple enhancing miliary nodules in the cerebral cortex, basal ganglia, thalamus, cerebellum, and brainstem. Some of those nodules also could be seen on T2-weighted imaging without Gd-DTPA, but were difficult to identify conclusively. A histopathologic examination at autopsy disclosed diffusely distributed miliary tumor nodules in a perivascular distribution without surrounding focal edema or reactive gliosis. Notably, this patient with miliary brain metastases developed disorientation followed by unconsciousness, which overshadowed other focal neurologic signs at that time. We should consider this pattern of brain dissemination when a cancer is associated with unexplained disturbance of consciousness. (orig.)

    A 36-year-old female elementary schoolteacher presented with aggregated serous papules surrounded by mild erythema, extending from both nasal wings/nostrils down to the upper lip. No improvement was seen following treatment of the lesions with topical antibiotics for impetigo. Potassium hydroxide (KOH) direct microscopy confirmed the presence of mycelia, and the infection was diagnosed as tinea faciei. The isolate was identified as Trichophyton mentagrophytes using morphological analysis and as Arthroderma benhamiae using genetic analysis. Here we describe that case and summarize the clinical features of other cases of A. benhamiae infection in Japan that have been reported in the literature.

    Full Text Available SUMMARY. The case is described of a 42 year-old male who presented with fever, haematuria, hypoxaemia, impaired liver function and a miliary pattern on chest X-ray while receiving intravesical BCG treatment for superficial bladder cancer. Initiation of antituberculous therapy resulted in rapid amelioration of the symptoms and the X-ray findings, and the patient left hospital in a good general state of health. Although M. bovis was not isolated from samples of sputum, bronchioalveolar lavage fluid (BALF or bronchial biopsy tissue, the prompt response to antituberculous therapy suggests an infectious aetiology due to microbial dissemination.

    A new 16-day echinoid early life stage (ELS) bioassay was developed to allow for prolonged observation of possible adverse effects during embryogenesis and larval development of the sea urchin Psammechinus miliaris. Subsequently, the newly developed bioassay was applied to study the effects of key marine persistent organic pollutants (POPs). Mortality, morphological abnormalities and larval development stages were quantified at specific time points during the 16-day experimental period. In contrast to amphibians and fish, P. miliaris early life development was not sensitive to dioxin-like toxicity in the prolonged early life stage test. Triclosan (TCS) levels higher than 500 nM were acutely toxic during embryo development. Morphological abnormalities were induced at concentrations higher than 50 nM hexabromocyclododecane (HBCD) and 1000 nM tetrabromobisphenol A (TBBPA). Larval development was delayed above 25 nM HBCD and 500 nM TBBPA. Heptadecafluorooctane sulfonic acid (PFOS) exposure slightly accelerated larval development at 9 days post-fertilization (dpf). However, the accelerated development was no longer observed at the end of the test period (16 dpf). The newly developed 16-day echinoid ELS bioassay proved to be sensitive to toxic effects of POPs that can be monitored for individual echinoid larvae. The most sensitive and dose related endpoint was the number of developmental penalty points. By manipulation of the housing conditions, the reproductive season could be extended from 3 to 9 months per year and the ELS experiments could be performed in artificial sea water as well.

    Full Text Available The pretreatment detection of an activating mutation of EGFR is now routinely performed in metastatic nonsquamous non-small cell lung cancer (NSCLC. The therapeutic impact of such a detection is major, as patients with advanced NSCLC exhibiting a mutation of exon 19 or 21 will benefit from EGFR-tyrosine kinase inhibitors (TKI. The presence of an EGFR resistance mutation, such as T790M in EGFR-TKI-naïve patients, is seldom looked for and is related either to a germinal mutation or to somatically mutated subclones. It has a negative predictive impact. We present the case of a patient with a lung papillary adenocarcinoma and miliary intrapulmonary metastases whose tumor displays a somatic complex heterozygous EGFR mutation, combining L858R (exon 21 and a primary resistance mutation T790M (exon 20, both detected by direct sequencing.

    The Antarctic Peninsula has experienced a rapid increase in atmospheric temperature over the last 50 years. Whether or not marine organisms thriving in this cold stenothermal environment are able to cope with warming is of concern. Here, we present changes to the growth and shell characteristics of the ecologically important, small and short lived brooding bivalve Lissarca miliaris from Signy Island, Antarctica. Using material collected from the 1970's to the present day, we show an increase in growth rate and adult shell deterioration accompanied by a decrease in offspring size, associated with an increase in annual average temperatures. Critical changes to the bivalve's ecology seen today evidence the problem of a shift in baseline since the onset of warming recorded in Antarctica. These small bivalves are demonstrating ecophysiological responses to subtle warming that, provided warming continues, could soon surpass a physiological tipping point, adding to warming associated threats such as increased predatory pressure and ocean acidification.

    Full Text Available Intracranial tuberculomas continue to be a serious complication of central nervous system tuberculosis. Multiple central nervous system tuberculoma is commonly associated with human immunodeficiency virus (HIV infection. The development of intracranial tuberculomas has been thought to be caused by hematogenous spread of tubercle bacilli on the surface of brain parenchyma from the primary site of infection. Here, we describe the case of a 5-year-old male child with severe protein energy malnutrition (Marasmus having large cervical lymphadenopathy and severe nutritional rickets with deformity at presentation. The child developed convulsions 20 days after initiation of antituberculous drugs, and neuroimaging confirmed multiple miliary tuberculomas of brain as primary etiology for the convulsions.

    Full Text Available Background: An increase in tuberculosis (TB incidence has been associated with human immunodeficiency virus (HIV. Aims: To describe the clinical characteristics and treatment outcome of patients with HIV and miliary TB treated with short-course intermittent chemotherapy in the absence of access to highly active antiretroviral therapy (HAART. Settings and Design: Prospective study of HIV infected adults referred to a TB clinic between July 1999 and July 2004. Materials and Methods: On diagnosis of miliary TB, patients were treated with a standard regimen of two months of isoniazid, rifampicin, ethambutol and pyrazinamide followed by four months of isoniazid and rifampicin (2EHRZ 3 /4RH 3 thrice weekly and followed up for 24 months. Patients were reviewed clinically every month and two sputa were collected. Chest radiographs and blood investigations were done at two months, end of treatment and every six months thereafter. Results: Of 498 patients with HIV and tuberculosis, 31 (6% were diagnosed as miliary tuberculosis. At diagnosis, sputum smear was positive for acid-fast bacilli (AFB in 14 patients (45% and Mycobacterium tuberculosis was isolated in 21 (68%. The mean CD4 cell count was 129 ± 125 cells/mm 3 . Twenty-five patients were declared cured at the end of treatment (81% while one (3% died and five (16% failed. The recurrence rate was 19.4/100 person-years and the median survival was 17 months (95% CI 14 to 20. None of the patients received antiretroviral therapy. Conclusions: Miliary TB tends to occur among HIV infected patients with severe immunosuppression. Though the initial response to short-course chemotherapy was encouraging, a high recurrence rate and mortality was observed indicating poor prognosis in HIV.

    Malignant pleural mesothelioma (MPM) is the aggressive disease typically spreading along the pleural surface and encasing the lung, leading to respiratory failure or cachexia. Rare cases with atypical clinical manifestation or presentation have been reported in MPM. We experienced a unique case of MPM concurrently associated with miliary pulmonary metastases and nephrotic syndrome. A 73-year-old Japanese man with past history of asbestos exposure was referred to our hospital for the investigation of the left pleural effusion. Chest computed tomography showed thickening of the left parietal pleura. Biopsy specimen of the pleura showed proliferating epithelioid tumor cells, leading to the pathological diagnosis of epithelioid MPM with the aid of immunohistochemistry. After the diagnosis of MPM, chemotherapy was performed without effect. Soon after the clinical diagnosis of progressive disease with skull metastasis, edema and weight gain appeared. Laboratory data met the criteria of nephrotic syndrome, and renal biopsy with electron microscopic examination revealed the minimal change disease. Steroid therapy was started but showed no effect. Around the same time of onset of nephrotic syndrome, multiple miliary lung nodules appeared on chest CT. Transbronchial biopsy specimen of the nodules showed the metastatic MPM in the lung. The patient died because of the worsening of the general condition. To our knowledge, this is the first case of MPM concurrently associated with multiple miliary pulmonary metastases and nephrotic syndrome.

    Activities of muraenids, primarily Gymnothorax moringa and Muraena miliaris, were observed on a Caribbean coral reef with a view to further understanding their role in the reef ecosystem. Other muraenid species included in the total of 198 sightings were Echidna catenata, Enchelycore nigricans, and an unidentified brown moray. The five species were unequally distributed among three basic habitats (sand, coral head, reef rock) available on the reef. Nine particular holes accounted for 52.5% of the total sightings, although hundreds of other seemingly appropriate sites were available. The eels (except M. miliaris) were transient with respect to given holes and particular sections of the reef. While some G. moringa were sighted in the same holes for several consecutive days, M. miliaris individuals remained in the same coral heads throughout the 6-week study period. Muraenids observed in this study showed high tolerances for and were tolerated by other fishes (including other morays) and invertebrates on the reef. They appeared to be opportunistic, roving predators and were not strictly nocturnal. Distinct behavioral interactions and displays between muraenids and reef fish were observed.

    Full Text Available Tuberculous osteomyelitis is rare and usually involves the vertebrae but is seldom found in the foot. The uncommon site and ability to mimic other disorders clinically and radiographically leads to diagnostic and therapeutic delays. We report a case of a 40-year-old man who initially presented to his podiatrist with intermittent pain and swelling of his right ankle and foot that lasted for a year. He also started to exhibit significant weight loss and unexplained fevers and was subsequently hospitalized for cellulitis of his right foot. On further workup, patient was found to have miliary tuberculosis (TB and acquired immunodeficiency syndrome (AIDS. Patient was treated with anti-TB therapy for 9 months and highly active anti-retroviral therapy. Our patient presented with ongoing chronic right foot and ankle pain that was proven to be secondary to TB osteomyelitis of cuneiform bones of the right ankle in the setting of AIDS. The patient's clinical presentation was unusual due to symptom duration and lack of systemic characteristics. Like our case, reported incidence of osteomyelitis of bone/joint in extrapulmonary TB is estimated to be 10%, and out of all bones/joint TB cases, only 1% are found to be in the foot.

    A 27-year-old man with a 4-month history of treatment for miliary tuberculosis at another hospital was admitted to our hospital for continued treatment. Computed tomography showed new lesions in the S8 area of the liver and spleen, despite resolution of chest radiographic findings. Because these new lesions were still present after 8 months of treatment, we performed laparoscopic drainage of the liver abscess. Purulent material drained from the lesion revealed positive polymerase chain reaction results for Mycobacterium tuberculosis, and identification of granuloma with infiltrating lymphocytes and plasma cells confirmed the diagnosis of tubercular liver abscess. Pathological changes in the spleen over the clinical course were also regarded as representing tubercular abscess. Postoperative course was good, and tuberculosis treatment ended after 12 months. Tubercular liver abscess subsequently showed prominent reduction, and the tubercular splenic abscess disappeared on abdominal ultrasonography. Tubercular hepatosplenic abscesses appearing during tubercular treatment are rare. We report this valuable case in which laparoscopic drainage of a liver abscess proved useful for diagnosis and treatment.

    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.

    Two novel thermo-alkali-tolerant crude xylanases namely MLK-01 (enzyme-A) and MLK-07 (enzyme-B) from Coprinellus disseminatus mitigated kappa numbers of Anthocephalus cadamba kraft-AQ pulps by 32.5 and 34.38%, improved brightness by 1.5 and 1.6% and viscosity by 5.75 and 6.47% after (A)XE(1) and (B)XE(1)-stages, respectively. The release of reducing sugars and chromophores was the highest during prebleaching of A. cadamba kraft-AQ pulp at enzyme doses of 5 and 10 IU/g, reaction times 90 and 120 min, reaction temperatures 75 and 65°C and consistency 10% for MLK-01 and MLK-07, respectively. MLK-07 was more efficient than MLK01 in terms of producing pulp brightness, improving mechanical strength properties and reducing pollution load. MLK-01 and MLK-07 reduced AOX by 19.51 and 42.77%, respectively at 4% chlorine demands with an increase in COD and colour due to removal of lignin carbohydrates complexes. A. cadamba kraft-AQ pulps treated with xylanases from MLK-01 to MLK-07 and followed by CEHH bleaching at half chlorine demand (2%) showed a drastic reduction in brightness with slight improvement in mechanical strength properties compared to pulp bleached at 4% chlorine demand. MLK-01 reduced AOX, COD and colour by 43.83, 39.03 and 27.71% and MLK-07 by 38.34, 40.48 and 30.77%, respectively at half chlorine demand compared to full chlorine demand (4%). pH variation during prebleaching of A. cadamba kraft-AQ pulps with strains MLK-01 and MLK-07 followed by CEHH bleaching sequences showed a decrease in pulp brightness, AOX, COD and colour with an increase in mechanical strength properties, pulp viscosity and PFI revolutions to get a beating level of 35 ± 1 °SR at full chlorine demand.

    In recent years, seasonal blooms of the dinoflagellate Noctiluca miliaris have appeared in the open-waters of the northern Arabian Sea (NAS). This study provides the first characterization of bacteria from a seasonal bloom of green Noctiluca of NAS (20°N-17°N and 64°E-70°E), during the spring-inter-monsoon cruise of Sagar Sampada 253, in March 2007. Bacterial growth as assessed by most-probable number (MPN) and plate counts, revealed `variable-physiotypes' over a wide range of salinities (0%-25% w/v NaCl), pH levels (5-8.5), and organic nutrient strengths, in comparison to non-bloom waters. MPN indices of bacteria in surface waters of bloom stations *DWK and *PRB, corresponded to (3.08-4.41)×103 cells/mL at 3.5% NaCl (w/v), and (2.82-9.49)×102 cells/mL at 25% (w/v) NaCl in tryptone-yeast extract broth (TYE). Plate counts were (1.12-4)×106 CFU/mL at 0% (w/v) NaCl, (1.28-3.9)×106 CFU/mL at 3.5% (w/v) NaCl, and (0.4-7)×104 CFU/mL at 25% NaCl (w/v) on TYE. One-tenth-strength Zobell's gave (0.6-3.74)×105 CFU/mL at pH 5 to (3.58-7.5)×105 CFU/mL at pH 8.5. These bacteria were identified to the genera Bacillus, Cellulomonas, Staphylococcus, Planococcus, Dietzia, Virgibacillus, Micrococcus, Sporosarcinae, Leucobacter, and Halomonas. The identity of three strains (GUFBSS253N2, GUFBSS253N30, and GUFBSS253N84) was confirmed through 16S rDNA sequence homology as Bacillus cohnii, Bacillus flexus, and Bacillus cereus. The ˜2-3-fold higher plate counts of culturable bacteria from the open-waters of the NAS indicate that these bacteria could critically determine the biogeochemical dynamics of the bloom and its milieu. The role of these bacteria in sustaining/terminating the bloom is under evaluation.

    In recent years,seasonal blooms of the dinoflagellate Noctiluca miliaris have appeared in the open-waters of the northern Arabian Sea (NAS).This study provides the first characterization of bacteria from a seasonal bloom of green Noctiluca ofNAS (20°N-17°N and 64°E-70°E),during the spring-inter-monsoon cruise ofSagar Sampada 253,in March 2007.Bacterial growth as assessed by most-probable number (MPN) and plate counts,revealed ‘variable-physiotypes' over a wide range of salinities (0%-25% w/v NaC1),pH levels (5-8.5),and organic nutrient strengths,in comparison to non-bloom waters.MPN indices of bacteria in surface waters of bloom stations *DWK and *PRB,corresponded to (3.08-4.41)× 103 cells/mL at 3.5%NaC1 (w/v),and (2.82-9.49)× 102 cells/mL at 25% (w/v) NaC1 in tryptone-yeast extract broth (TYE).Plate counts were (1.12-4) × 106 CFU/mL at 0% (w/v) NaCl,(1.28-3.9) × 106 CFU/mL at 3.5% (w/v) NaC1,and (0.4-7)× 104 CFU/mL at 25% NaC1 (w/v) on TYE.One-tenth-strength Zobell's gave (0.6-3.74)× 105 CFU/mL at pH 5 to (3.58-7.5)× 105 CFU/mL at pH 8.5.These bacteria were identified to the genera Bacillus,Cellulomonas,Staphylococcus,Planococcus,Dietzia,Virgibacillus,Micrococcus,Sporosarcinae,Leucobacter,and Halomonas.The identity of three strains (GUFBSS253N2,GUFBSS253N30,and GUFBSS253N84) was confirmed through 16S rDNA sequence homology as Bacillus cohnii,Bacillusflexus,and Bacillus cereus.The ~2-3-fold higher plate counts of culturable bacteria from the open-waters of the NAS indicate that these bacteria could critically determine the biogeochemical dynamics of the bloom and its milieu.The role of these bacteria in sustaining/terminating the bloom is under evaluation.

    Pulmonary infections and lung cancer can resemble each other on radiographic images, which makes it difficult to diagnosis accurately and apply an appropriate therapy. Here we report two cases that two postoperative patients with lung adenocarcinoma developed diffuse nodules in bilateral lungs in a month which needed to be distinguished between metastatic malignancies and infectious diseases. Although there are much similarities in disease characteristics of two cases, patient in case one was diagnosed as acute miliary pulmonary tuberculosis (TB) while patient in case two was diagnosed as metastatic disease. The symptoms and pulmonary foci on CT scan of patient in case one improved distinctly after the immediate anti-TB treatment, but the disease of patient in case two progressed after chemotherapy. These findings caution us that differential diagnosis is crucial and have significance in guiding clinical work.

    Full Text Available Genitourinary tuberculosis (GUTB is difficult to diagnose in the earlier stage owing to the non-specific symptoms. Usually, renal tuberculous involvement is unilateral and the imaging finding is renal calcification, but associated calcifications of bilateral ureter and bladder are rare. We report a 66-year-old man who presented with diffuse calcification of the urinary system (including bilateral pelvicalyceal system, both ureters and bladder and disseminated miliary tuberculosis due to GUTB. He had been misdiagnosed with urinary tract infection and urinary lithiasis for two years before the diagnosis of GUTB was confirmed by microbiological examination of the urine. This case highlights the importance of maintaining a high index of clinical suspicion for GUTB.

    A 63-year-old man with chronic myelomonocytic leukemia was admitted to our hospital with miliary tuberculosis. He received anti-tuberculosis drugs: isoniazid (INH), rifampicin (RFP), ethambutol (EB), and pyrazinamide (PZA). His condition clearly and immediately improved after the therapy, but he experienced a high fever of about 38°C every day from 1 month after the initiation of the therapy. Drug-induced fever and tumor fever were suspected as causes, but the etiology could not be determined. The tuberculosis was identified as an INH-resistant strain, so INH was stopped and levofloxacin (LVFX) was introduced, with streptomycin (SM), in addition to RFP, EB, and PZA. At 2 months after the initiation of the therapy (about one week after the change in the anti-tuberculosis drug regimen), his spinal fluid was examined, given his complaints of headache and vomiting. The spinal fluid analysis revealed invasion of lymphocytic inflammatory cells and high adenosine deaminase activity; the patient was thus diagnosed with tuberculous meningitis. His condition gradually improved after the changing of the anti-tuberculosis drugs. Thus, to summarize, the tuberculous meningitis had worsened paradoxically despite his systemic improvement, although it was successfully treated by the addition of LVFX and SM. We must keep in mind that a potential cause of fever during anti-tuberculosis therapy may be INH-resistant tuberculous meningitis.

  18. Differential adaptations between cold-stenothermal environments in the bivalve Lissarca cf. miliaris (Philobryidae) from the Scotia Sea islands and Antarctic Peninsula

    The cold stenothermal nature of the Southern Ocean, and highly adapted fauna living within, raises the question of how much intra-specific variation there is among invertebrate populations, and how variation may have a role in speciation processes through ecological divergence, natural selection, and reproductive isolation. Despite decades of collecting biological material, this question remains largely unanswered, and many studies compare ‘populations' of pooled material from wide geographic ranges to compensate for sampling constraints. In this study, variations in ecophysiological traits are explored by measuring growth, reproduction, and shell morphology among six populations of the small bivalve Lissarca cf. miliaris (Philippi, 1845) from the Southern Ocean, which experience subtle differences in temperature, disturbance, and food availability. There are significant differences in shell morphology and growth among different populations and slower growth rates at higher latitude populations. Prodissoconch sizes show an inverse ‘U' shaped relationship with latitude, and are correlated with egg size at South Georgia and King George Island's Potter Cove. Higher brood sizes at the South Georgia population represent a trade-off with lower egg size, and correlate with shell morphology by offering lower internal capacity to brood young. Lower investment into offspring and morphological variations in L. cf. miliaris highlight the importance of local scale environmental variations on species' ecology. These variations in physical traits appear to be underestimated in the Southern Ocean, but may be important drivers of ecological divergence and speciation, which should be considered in future genetic investigations on different invertebrate populations.

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

    Thyroid cancer is relatively a rare cancer; about 1% from all cancers: between 10 and 1591 of patients with differentiated thyroid cancer develop micro or macro-nodular pulmonary metastases. In this study we examined the characteristics and evolution after treatment of 10 patients with micro-nodular or miliary metastases of well-differentiated thyroid carcinoma. Total body scintigraphy with 131 iodine, chest X-ray or CT scan, and thyroglobulin assay were performed for all patients. The treatment was iodine 131 (3. 7 GBq). therapeutic 131 iodine scan was done for all patients seven days after the 131 administration. The effect of 131 iodine treatment was evaluated by means of changes in the number and size of lung metastases on the total body scintigraphy with 131 iodine and by serum thyroglobulin levels six months after 131 iodine ablation, they all received L-thyroxine (2,4 {mu}g/kg/j). The minimum duration of follow-up was 12 months. There were six females and four males within a range of 13-70 years old. Eight had papillary and two follicular thyroid cancer. These 10 patients benefited 131 iodine therapy. The effect of 131 iodine treatment and the prognostic values of the following variables mere examined: age at the time of 131 iodine. treatment and histological findings. The miliary was rarely diagnosed on the initial investigation. only in to o cases by 131 iodine scar. alter surgery. two cases by chest X-ray, and two cases by CT scan, the initial thyroglobulin levels was very high in seven cases, between 10 and 40 ng/ml in one case and less than 10 ng/ml in two cases. These results indicate that age, 131 iodine uptake. histological findings and the presence of other metastases are important factors in predicting the effects of 131 treatment for pulmonary metastases of well-differentiated thyroid carcinoma. Among all the variables studied. the best prognosis for survival was demonstrated by increased 131 uptake in pulmonary metastases and by early diagnosis

Conclusion We described typical cases of a rare diseases, hemifacial atrophy and "en coup de sabre" scleroderma. In the patient diagnosed with Parry-Romberg syndrome, with Borrelia burgdoferi infection and with minor neurological symptoms, despite a four-year case history, there was a lack of proper diagnosis and treatment. In the second patient only skin changes without any neurological symptoms could be observed and only a precise neurological diagnosis revealed the presence of CNS tumor.

    A 42-year-old female with immunoglobulin A deficiency and recurrent sinopulmonary infections underwent thyroidectomy for papillary thyroid cancer (PTC). Follow-up {sup 123}I scintigraphy demonstrated diffuse pulmonary uptake, suggesting metastatic disease. However, subsequent pathologic, biochemical and radiographic testing proved that she was in fact disease free, and the initial {sup 123}I pulmonary uptake was identified as a false positive. Inflammatory conditions may rarely cause iodine uptake in non-thyroidal tissues due to local retention, organification, and/or immunologic utilization. To avoid exposing patients to unnecessary treatments, it is critical for clinicians to recognize that comorbid pulmonary conditions may mimic metastatic PTC on radioiodine scintigraphy.

    Full Text Available Dermatophytoses are the most common fungal infections of the skin. In the clinical practise, tinea pedis is most common clinical form of dermatophytosis. Other clinical forms are tinea cruris, tinea capitis, tinea corporis and tinea faciei. Tinea faciei is a rare form of dermatophytosis of glabrous skin, characterized by a well- circumscribed erythematous patch, and is more commonly misdiagnosed with some dermatologic diseases as seborrheic dermatitis, contact dermatitis, polymorphic light eruption and lymphocytic infiltrations. In addition, it is reported its clinical forms resembling folliculitis, perioral dermatitis, impetigo and sycosis. To date, a few cases of dermatophytosis involving eyelid were presented in the literature. Here, we present a patient who has an erythematous and fine scaly patch on her eyelid and who is diagnosed as dermatophytic blepharitis by helping typical tinea corporis on her wrist.

    Ovid's "De medicamine faciei feminae" contains the astonishing sentence "Culta placent - all that is artificial is beautiful". In his "Éloge du maquillage" Baudelaire, buidling on Ovid's argument, states that first culture as picture and construction of beauty brings forth the truth of Nature and claims that cosmetics that allow errors of beauty to disappear artificially produce the true fulfillment of human nature. The present article looks into the historical roots of the body images that have emerged in modern times and attempts to derive structural devices for an ethical assessment of the potential we have to enhance human nature.

    1977-08-01

    Four patients developed miliary tuberculosis while undergoing chronic hemodialysis. Two patients had diabetes mellitus. Three of the four patients were hemodialyzed 18--24 months prior to the onset of symptoms. Signs and symptoms included prolonged fever, pleural effusion, pericarditis with pericardial effusion, abdominal pain, weight loss, and ascites. All patients were PPD negative and without historical or radiographic evidence of latent tuberculosis. Disseminated tuberculosis was proven at autopsy in three patients. M. tuberculosis was eventually recovered from pleural fluid and urine in the fourth patient. The immune deficiencies of chronic renal failure and diabetes mellitus are suspected predisposing factors to the development of miliary tuberculosis in these patients.

    2015-01-01

    An unusual case of chromoblastomycosis is reported, it resembled dermatophytosis, tinea faciei due to the presence of a well-demarcated scaly ery- thematous patch on the face. The patient was a 63-year-old farmer from central Thailand, who had the skin lesion for 10 years. Mycological and histopathologi- cal investigations of scales and skin biopsy specimen revealed a granulomatous infiltrate with sclerotic bodies, the hallmark of chromoblastomycosis. The infec- tion showed only localized superficial expansion with a scaly patch suggesting a new clinical type of the disease. The causative organism was identified by DNA sequencing as Rhinocladiella phaeophora. R.phaeophora originally was a saprophytic dematiaceous fungus recovered from maize field soil from Colombia. The case was unusual in its clinical presentation and this is the first case of chromoblastomycosis reported to be caused by a new opportunistic species of the genus Rhinocladiella. The disease was not responsive to itraconazole, but was later treated successfully with terbinafine.

    Full Text Available Abstract Background Disseminated mycobacterium avium complex (MAC occurs mainly in immunocompromised hosts, which is associated with abnormal cellular immunity. Case presentation A 26-year-old pregnant woman presented with fever and general weakness. Miliary lung nodules were noted on chest X-ray. Under the impression of miliary tuberculosis, anti-tuberculosis medication was administered. However, the patient was not improved. Further work-up demonstrated MAC in the sputum and placenta. The patient was treated successfully with clarithromycin-based combination regimen. Conclusion This appears to be the first case of disseminated MAC in an otherwise healthy pregnant woman. Clinicians should be alert for the diagnosis of MAC infection in diverse clinical conditions.

    Full Text Available Multiple cerebral tuberculomas complicating miliary tuberculosis are a rare occurrence. It is rarer still for multiple cerebral tuberculomas to present without focal neurological deficits. We report the case of a middle-aged Nigerian male with the co-morbidity of miliary tuberculosis and multiple cerebral tuberculomaswho presented without focal neurological deficits buthad complete resolution of symptoms and signs following a 6-month course of antituberculous therapy. This unique case emphasizes the need for a high index of suspicion in the diagnosis of atypical presentations of cerebral tuberculomas while also further illustrating the place of computed tomographic scan of the brain in diagnosis. The case also illustrates the place of therapeutic trial in management.

  11. Rare lung manifestation of multifocal micronodular pneumocyte hyperplasia in a teenage girl with tuberous sclerosis complex

    2016-08-15

    Multifocal micronodular pneumocyte hyperplasia (MMPH) is a relatively rare pulmonary disorder that can be associated with tuberous sclerosis complex (TSC). It has been rarely reported in children or adolescents. MMPH is a hamartomatous process of the lung with multiple small nodules, composed of type II pneumocytes. Plain radiography and chest CT in MMPH may demonstrate numerous small nodules measuring 1-10 mm in diameters, distributed randomly throughout both lungs. If MMPH is an initial presentation of TSC, and unless we are familiar with this lung manifestation of TSC, radiologic findings can mimic miliary tuberculosis or metastatic disease. We report a teenage girl with TSC and histologically confirmed MMPH which mimicked miliary tuberculosis at the initial presentation.

    Tuberculosis and sarcoidosis are multisystem diseases having different aetiology and management; however, they have similar clinical and histological characteristics. Very rarely they may coexist. We report a rare case of a 38-year-old woman who presented with chronic cough, low-grade fever and respiratory distress that was initially diagnosed as miliary tuberculosis. Diagnosis was supported by positive mycobacterial culture and initially responded to antitubercular treatment, but later recurrences led to further investigations and the diagnosis of coexisting sarcoidosis.

    Human leukocyte antigen-G (HLA-G) is an anti-inflammatory and immunosuppressive molecule that can modulate immune cell activation. The role of HLA-G in tuberculosis, an immune-mediated and chronic bacterial disease remains to be elucidated. We investigated the expression profile of soluble and membrane bound HLA-G in pulmonary TB (PTB), TB pleural effusion (TB-PE, localized disease) and Miliary TB (disseminated form). The expression of HLA-G receptor, ILT-2 was also determined on the immune cells. We observed that the plasma sHLA-G levels were significantly increased in Miliary TB than in TB-PE patients. In contrast, immunophenotyping revealed that the percent frequency of CD3(+) T cells expressing HLA-G was significantly reduced in Miliary TB as compared to TB-PE, whereas frequency of CD14(+) monocytes expressing HLA-G was significantly higher in TB-PE patients. Strikingly in the TB-PE cases, comparison of disease site, i.e. pleural effusion with peripheral blood showed increased expression of both soluble and surface HLA-G, whereas ILT-2 expressing cells were reduced at the local disease site. Furthermore, we demonstrated that in TB-PE cases, HLA-G expression on CD3(+) T cells was influenced by broad spectrum MMP inhibitor. Thus, differential expression of HLA-G could potentially be a useful biomarker to distinguish different states of TB disease.

  20. Ecological release and venom evolution of a predatory marine snail at Easter Island.

    Thomas F Duda

    Full Text Available BACKGROUND: Ecological release is coupled with adaptive radiation and ecological diversification yet little is known about the molecular basis of phenotypic changes associated with this phenomenon. The venomous, predatory marine gastropod Conus miliaris has undergone ecological release and exhibits increased dietary breadth at Easter Island. METHODOLOGY/PRINCIPAL FINDINGS: We examined the extent of genetic differentiation of two genes expressed in the venom of C. miliaris among samples from Easter Island, American Samoa and Guam. The population from Easter Island exhibits unique frequencies of alleles that encode distinct peptides at both loci. Levels of divergence at these loci exceed observed levels of divergence observed at a mitochondrial gene region at Easter Island. CONCLUSIONS/SIGNIFICANCE: Patterns of genetic variation at two genes expressed in the venom of this C. miliaris suggest that selection has operated at these genes and contributed to the divergence of venom composition at Easter Island. These results show that ecological release is associated with strong selection pressures that promote the evolution of new phenotypes.

    By an extensive standardisation of the indirect immunofluorescence for the demonstration espeially of mitochondrial antibodies we succeeded in recognizing atypical fluorescence patterns and in describing their exact localisation. On the basis of absorption studies with mitochondrias, microsomas and ribosomas by comparative observation of sections of liver, stomach and kidneys of rats the preferred sort of reaction and the intensity of fluorescence of antibodies against mitochondria, microsomas and ribosomas were empirically established. Antimitochondrial antibodies react above all with the parietal cells of the stomach and the distal epithelia of the tubulus of the kidney. Antibodies against microsomas of liver and kidney are characterized by a brilliant diffuse cytoplasmatic fluorescence of the hepatocytes and by a comparatively weaker fluorescence of exclusively proximal tubuli of the kidneys of rats. Antibodies against ribosomas lead to a fluorescence especially of the main cells of the stomach. The differentiation of several cytoplasmatic antibodies is among others of interest for the diagnosis of certain autoimmune diseases. Although there are numerous still unclear findings and "overlap" phenomena the existence of high titre antibodies against mitochondrias speaks for a primarily biliary cirrhosis or a pseudo-LE-syndrome, the existence of antibodies against microsomas of kidney and liver of rats for a special form of a chronically active hepatitis and the existence of the very rare antibodies against ribosomas for an active lupus erythematodes disseminatus.

    Objective To investigate the risk factors attributable to tuberculosis-related deaths in areas with human immunodeficiency virus (HIV) infection epidemics. Methods A prospective cohort study of newly registered patients in tuberculosis (TB) dispensaries in six representative Chinese provinces was conducted from September 1, 2009 to August 31, 2011. Risk factors for TB-associated death were identified through logistic regression analysis. Results Of 19,103 newly registered pulmonary TB patients, 925 (4.8%) were found to be HIV-positive. Miliary TB and acid-fast bacillus smear-negative TB were more common among these patients. Out of a total of 322 (1.7%) deaths that occurred during TB treatment, 85 (26%) of the patients were co-infected with HIV. Multivariate analysis revealed that HIV infection was the strongest predictor of death [adjusted odds ratio (aOR) 7.86]. Other significant mortality risk factors included presentation with miliary TB (aOR 4.10; 95% confidence interval: 2.14-7.88), ≥35 years of age (aOR 3.04), non-Han ethnicity (aOR 1.67), and farming as an occupation (aOR 1.59). For patients with TB/HIV co-infection, miliary TB was the strongest risk factor for death (aOR 5.48). A low CD4 count (≤200 cells/µL) (aOR 3.27) at the time of TB treatment initiation and a lack of antiretroviral therapy (ART) administration (aOR 3.78) were also correlated with an increased risk of death. Conclusion Infection with HIV was independently associated with increased mortality during TB treatment. Offering HIV testing at the time of diagnosis with TB, early TB diagnosis among HIV/acquired immunodeficiency syndrome patients, and the timely provision of ART were identified as the key approaches that could reduce the number of HIV-associated TB deaths.

    To investigate the impact of PET and PET/CT scanning on decision-making in management planning and to identify the optimal setting for selecting candidates for surgery in suspicious recurrent ovarian cancer. A retrospective chart review was performed in patients with possible recurrent ovarian cancer after primary optimal cytoreduction and taxane/carboplatin chemotherapy who had undergone FDG PET or FDG PET/CT scans from July 2002 to August 2008 to help make treatment decisions. The analysis included 44 patients who had undergone a total of 89 PET scans. The positive PET scans were classified as follows. (1) localized (one or two localized sites of FDG uptake), (2) multiple (three or more sites of FDG uptake), (3) diffuse (extensive low-grade activity outlining serosal and peritoneal surfaces). Of the 89 PET scans, 52 (58.4 %) led to a change in management plan. The total number of patients in whom cytoreductive surgery was selected as the treatment of choice increased from 12 to 35. Miliary disseminated disease, which was not detected by PET scan, was found in 22.2 % of those receiving surgery. Miliary disseminated disease was detected in 6 of the 12 patients with recurrent disease whose treatment-free interval (TFI) was <12 months, whereas none of those with a TFI of ≥12 months had such disease (P = 0.0031). PET or PET/CT is useful for selecting candidates for cytoreductive surgery among patients with recurrent ovarian cancer. To avoid surgical attempts in those with miliary dissemination, patients with a TFI of ≥12 months are the best candidates for cytoreductive surgery. (orig.)

    A 62-year-old Indian with diabetic nephropathy controlled with metformin, developed miliary tuberculosis for which he was treated with rifampicin, isoniazid and ethambutol. Soon afterwards he developed cholestatic hepatitis and visual disturbance. Rifampicin and ethambutol were stopped. Streptomycin caused vertigo and had to be stopped. The introduction of para-aminosalicylic acid (PAS) led to hypoglycaemic coma. Metformin was stopped. Hypoglycaemic coma recurred. PAS was stopped and the patient's blood glucose concentrations became normal. Treatment with isoniazid and ethambutol led to total recovery from pulmonary tuberculosis. The induction of hypoglycaemia with PAS in this patient suggests a potential role for PAS in the treatment of diabetes mellitus.

    Pruritic skin diseases in the cat are best approached in a problem-oriented fashion. The presentations of pruritic skin disease in the cat include miliary dermatitis, pruritus of the head, scaling and crusting dermatoses, alopecia, erythroderma and exfoliation, eosinophilic granuloma complex, macular and pustular eruptions, and pruritic nodular dermatoses. There is a specific differential diagnosis for each presentation. A rational diagnostic plan, based on the likelihood of each disease in the differential diagnosis, may be formulated for each presentation of pruritus in the cat.

    2015-01-01

    Tuberculosis has made a comeback in recent years. This upsurge has been attributed to factors such as increased immigration and the human immunodeficiency virus epidemic. Primary pulmonary tuberculosis manifests radiologically with parenchymal involvement, lymph node involvement, pleural effusion, and/or miliary disease. In post-primary tuberculosis, the earliest radiological sign is small nodules and branching centrilobular lesions that increase in size and coalesce to form ill-defined patchy consolidations; cavitations are very characteristic of active disease. The aim of this article is to describe the radiologic findings for pulmonary tuberculosis and its complications.

    Intramedullary tuberculoma is rare, and there has been no report of concurrent intramedullary and intracerebral tuberculomas. We report a 30-year-old man with miliary tuberculosis of the lung. He suffered sudden paraplegia due to tuberculomas in the thoracic spinal cord and MRI showed more tuberculomas in the cervical spinal cord, brain stem, and cerebral and cerebellar hemispheres. The tuberculomas were isointense on the T1-weighted images, and hyperintense on the T2-weighted images; there was marked enhancement with intravenous gadolinium-DTPA. All the tuberculomas were very small 1 year after antituberculous chemotherapy. (orig.)

    High-resolution CT (HRCT) findings of several chest complications occurring in leukemic patients were reviewed. Although most entities show non-specific HRCT findings including ground-glass opacity and air-space consolidation, characteristic findings are observed in several pulmonary complications including Pneumocystis carinii pneumonia, fungal infections, miliary tuberculosis, leukemic infiltration, pulmonary edema, bronchiolitis obliterans, and bronchiolitis obliterans organizing pneumonia. A combination of these characteristic HRCT findings and the information obtained from the clinical setting may help in achieving a correct diagnosis of chest complications occurring in leukemic patients.

    We report a case of 60-year old male who had difficulty in breathing as well as in swallowing. On examination, he was found to be having proliferative growth of epiglottis and right aryepiglottic fold mimicking neoplasm. So emergency tracheostomy was performed and biopsy taken. He was found to be having asymptomatic miliary mottling on routine x-ray chest PA view. Further on HRCT, it turned out to be lesion suggesting tubercular etiology. Histopathology (epiglottic biopsy) report confirmed the whole process as tubercular. The patient recovered promptly in due course with anti-tubercular treatment. Point remains to be seen that if we can avoid tracheostomy and its complications in such cases.

    A case of the mass occurrence of a disease in the aquarium fish species Betta splendens is described; morphologically the disease was characterized by the finding of large dermal changes located mainly in the dorsal part and by miliary granulomata in liver, spleen and kidneys. The granulomata consisted of epitheloid light cells with centrally located necrosis. Gram-negative bacteria with morphological and biochemical characteristics corresponding to the bacterial species Edwardsiella tarda were isolated from the kidneys, liver and from the dermal lesion. The characteristics of the strains isolated by us were compared with the reference Edwardsiella strain (Bth 1/64) obtained from the Czechoslovak collection of type cultures, Prague.

    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.

    Fungal infections of the skin and nails are common global problems with attendant morbidity among affected individuals. Children are mostly affected due to predisposing factors such as overcrowding and low socioeconomic factors. The aim of this study was to determine the prevalence and the clinical patterns of superficial fungal infections among primary school children in Ile-Ife. A multistage sampling was conducted to select eight hundred pupils from ten primary schools in Ile-Ife. Data on epidemiological characteristics and clinical history was collected using a semistructured questionnaire and skin scrapings were done. The prevalence of superficial fungal infections among the 800 respondents was 35.0%. Male pupils constituted 51.0% of respondents while the females were 49.0%. The mean age for all the respondents was 9.42 ± 2.00. Tinea capitis was the commonest infection with a prevalence of 26.9% and tinea unguium, tinea corporis, and tinea faciei had a prevalence of 0.8%, 0.6%, and 0.5%, respectively. Tinea manuum had the least prevalence of 0.1%. Pityriasis versicolor had a prevalence of 4.4%. Microsporum audouinii was the leading organism isolated. The study shows that the prevalence of superficial fungal infection (SFI) among primary school children in Ile-Ife is high with tinea capitis as the commonest SFI. PMID:25574161

    1998-11-01

    Three-dimensional distribution of foci of diffuse lung disease was evaluated by CT image, and it was examined whether each lung disease could be diagnosed by different distribution. Subjects were 120 cases (idiopathic interstitial pneumonia 15 cases, sarcoidosis 23 cases, miliary tuberculosis 10 cases, diffuse panbronchiolitis 7 cases, chronic pulmonary emphysema 6 cases, pulmonary metastasis 9 cases, SLE 6 cases, PSS 8 cases, dermatomyositis (DM) 6 cases, RA 7 cases, SjS 9 cases and others 14 cases). CT image was obtained from apex to base of lung with 10 mm gapless. The image was divided into three parts in both head-tail direction and back-front direction, and two parts in cortex medulla direction, and the ratio of foci to whole in each part was evaluated in five phases, and the part with the highest ratio was determined as the predominant side. In idiopathic interstitial pneumonia, sarcoidosis, miliary tuberculosis, diffuse panbronchiolitis, chronic pulmonary emphysema, pulmonary metastasis, PSS and DM, the predominant side was confirmed, respectively, and usefulness of differential diagnosis was recognized. Constant distribution wasn't recognized in SLE, RA and SjS, because the state of disease was not always same in the foci of these diseases. (K.H.)

  2. Sediment Burial Intolerance of Marine Macroinvertebrates.

    Directory of Open Access Journals (Sweden)

    Vicki J Hendrick

    Full Text Available The marine environment contains suspended particulate matter which originates from natural and anthropogenic sources. Settlement of this material can leave benthic organisms susceptible to smothering, especially if burial is sudden i.e. following storms or activities such as dredging. Their survival will depend on their tolerance to, and their ability to escape from burial. Here we present data from a multi-factorial experiment measuring burial responses incorporating duration, sediment fraction and depth. Six macroinvertebrates commonly found in sediment rich environments were selected for their commercial and/or conservation importance. Assessments revealed that the brittle star (Ophiura ophiura, the queen scallop (Aequipecten opercularis and the sea squirt (Ciona intestinalis were all highly intolerant to burial whilst the green urchin (Psammichinus miliaris and the anemone (Sagartiogeton laceratus, showed intermediate and low intolerance respectively, to burial. The least intolerant, with very high survival was the Ross worm (Sabellaria spinulosa. With the exception of C. intestinalis, increasing duration and depth of burial with finer sediment fractions resulted in increased mortality for all species assessed. For C. intestinalis depth of burial and sediment fraction were found to be inconsequential since there was complete mortality of all specimens buried for more than one day. When burial emergence was assessed O. ophiura emerged most frequently, followed by P. miliaris. The former emerged most frequently from the medium and fine sediments whereas P. miliaris emerged more frequently from coarse sediment. Both A. opercularis and S. laceratus showed similar emergence responses over time, with A. opercularis emerging more frequently under coarse sediments. The frequency of emergence of S. laceratus increased with progressively finer sediment and C. intestinalis did not emerge from burial irrespective of sediment fraction or depth. Finally

    2009-01-01

    Full Text Available Background: Cutaneous fungal infections are common in Tehran, Iran, and causative organisms include dermatophytes, yeasts and non-dermatophyte molds. The prevalence of superficial mycosis infections has risen to such a level that skin mycoses now affect more than 20-25% of the world′s population, making them the most frequent form of infection. Aims: Our aim was to determine the prevalence of superficial cutaneous fungal infections especially dermatophytosis in our Medical Mycology Laboratory in the Pasteur Institute of Iran, Tehran. Methods: A total of 17,573 specimens were collected from clinically suspected tinea corporis, tinea cruris, tinea capitis, tinea faciei, tinea pedis, tinea manuum and finger and toe onychomycosis from 2000 to 2005. Patients were referred to our laboratory for direct examination, fungal culture and identification. The incidence of each species was thus calculated. Results: Dermatophytes remain the most commonly isolated fungal organisms, except from clinically suspected finger onychomycosis, in which case Candida species comprise> 7% of the isolates. Epidermophyton floccosum remains the most prevalent fungal pathogen and increased incidence of this species was observed in tinea cruris. Trichophyton tonsurans continues to increase in incidence. Conclusion: This study identifies the epidemiologic trends and the predominant organisms causing dermatophytosis in Tehran, Iran. These data can be used to ascertain the past and present trends in incidence, predict the adequacy of our current pharmacologic repertoire and provide insight into future developments. Consideration of the current epidemiologic trends in the incidence of cutaneous fungal pathogens is of key importance to investigational effort, diagnosis and treatment.

    Allergies are often suspected in cats and they are mainly hypersensitivity reactions against insect bites, food- or environmental allergens. Cats, with non flea induced atopic dermatitis, normally present with one oft he following reaction patterns: miliary dermatitis, eosinophilic dermatitis, selfinduced alopecia or head and neck excoriations. None of these reaction patterns is nevertheless pathognomonic for allergic dermatitis, therefore the diagnosis is based on the one hand on the exclusion of similar diseases on the other hand on the successful response on a certain therapy. Recently a study on the clinical presentation of cats with non flea induced atopic dermatitis was published. In this study certain criteria for diagnosing atopy in cats were proposed. For therapy of allergic cats cyclosporin, glucocorticoids, antihistamines, hypoallergenic diets and allergen specific immunotherapy are used. This article should provide a recent overview on the clinical symptoms, diagnosis and therapy of feline allergic dermatitis.

    Twenty-one cats were treated with megestrol acetate because they were showing clinical signs associated with one of the following problems: eosinophilic ulcer, eosinophilic plaque, neurodermatitis, endocrine alopecia and miliary dermatitis. The dosage schedule was 5 mg orally per day per cat for seven days, then 5 mg every three days for 21 days. In all cats, we noted a good improvement of the lesions as soon as treatment was started. In 25% of the patients, one treatment schedule was sufficient to control the skin disease for at least 18 months. In the remaining 75%, two treatment schedules and/or a maintenance dosage had to be established.Side effects encountered were increased appetite, personality changes and depression.

    Full Text Available Despite the high prevalence of tuberculosis (TB worldwide, pancreatic TB is rare. When present, pancreatic TB is frequently associated with miliary TB, often in immunocompromised hosts. Pancreatic TB may present as a pancreatic abscess, acute or chronic pancreatitis, and cystic or solid pancreatic masses. We present a case of an immunocompetent patient who presented with two discrete pancreatic masses and was subsequently diagnosed with isolated pancreatic TB. This case suggests that clinicians should have a heightened suspicion of pancreatic TB when faced with discrete pancreatic lesions, especially in patients from areas where the infection is endemic. Such recognition may lead to appropriate diagnostic testing, and possible resolution of pancreatic lesions with antituberculin therapy.

    Full Text Available Post-kala-azar dermal leishmaniasis (PKDL is rarely reported in South America. In spite of the fact that there are many reports about the association of visceral leishmaniasis and AIDS, PKDL is very uncommon in HIV-positive patients, and so far only four cases have been documented in the literature. We present another case with unusual clinicopathological aspects. The patient, a 28-year-old male, from Salvador, Bahia (an endemic area presented with clinical manifestations of visceral leishmaniasis three years after the diagnosis of AIDS. During treatment for visceral leishmaniasis he developed disseminated miliary papules. Microscopically, the skin biopsy showed a "saw-tooth" pattern with a lichenoid mononuclear infiltrate simulating lichen planus. The histopathological diagnosis was achieved through the finding of amastigotes. The authors discuss the clinicopathological aspects of this case based on a review of the specific literature.

    Lymphobronchial tuberculosis (TB) is tuberculous lymphadenopathy involving the airways, which is particularly common in children. To describe CT findings of lymphobronchial TB in children, the parenchymal complications and associated abnormalities. CT scans of children with lymphobronchial TB were reviewed retrospectively. Lymphadenopathy, bronchial narrowing, parenchymal complications and associations were documented. Infants comprised 51% of patients. The commonest site of lymphadenopathy was the subcarinal mediastinum (97% of patients). Bronchial compression was seen in all children (259 bronchi, of these 28% the bronchus intermedius) with severe or complete stenosis in 23% of affected bronchi. Parenchymal complications were present in 94% of patients, including consolidation (88%), breakdown (42%), air trapping (38%), expansile pneumonia (28%), collapse (17%) and bronchiectasis (9%), all predominantly on the right side (63%). Associated abnormalities included ovoid lesions, miliary nodules, pleural disease and intracavitary bodies. Airway compression was more severe in infants and most commonly involved the bronchus intermedius. Numerous parenchymal complications were documented, all showing right-side predominance. (orig.)

    Full Text Available Extrapulmonary tuberculosis is a bacterial infection that occurs outside the lung parenchyma. It is caused by different types of mycobacteria; the most common causative agent in humans is Mycobacterium tuberculosis. The case of a 17-year-old Angolan patient treated in a municipal hospital in Angola due to severe abdominal pain with generalized peritoneal reaction is presented. Several tests were performed, but they did not clarify the patient’s condition. Finally, she underwent surgery and an omental biopsy was taken. The histological study revealed the presence of tuberculoid granulomas, which led to the diagnosis of miliary tuberculosis. Cases of acute abdomen due to tuberculous peritonitis are very uncommon, in fact, this is the first case seen by the author of this report in forty years practicing as a surgeon.

  13. Lupus vulgaris with squamous cell carcinoma.

    2007-12-01

    Tuberculosis is still a significant problem in developing countries. Cutaneous forms of tuberculosis account for approximately 10% of all cases of extrapulmonary tuberculosis. Cutaneous tuberculosis may be because of true infection with Mycobacterium tuberculosis or because of tuberculids. Tuberculids are immunological reactions to haematogenously spread antigenic components of M. tuberculosis. True cutaneous tuberculosis may be because of inoculation or haematogenous spread of M. tuberculosis to the skin. Lupus vulgaris is the commonest form of true cutaneous tuberculosis. Other forms of true cutaneous tuberculosis are tuberculous chancre, tuberculosis verrucosa cutis, scrofuloderma, periorificial tuberculosis and miliary tuberculosis of the skin. Lupus vulgaris is usually chronic and progressive. It occurs in patients with moderate to high immunity against M. tuberculosis as evidenced by strongly positive tuberculin test. Long-standing cases of lupus vulgaris may be complicated by squamous cell carcinoma (SCC). We describe a patient who had undiagnosed lupus vulgaris for 35 years until she developed SCC on the lesion of lupus vulgaris.

    Patients receiving treatment for tuberculosis may experience an unexpected deterioration of their disease; this is known as a paradoxical reaction. We present the case of a 59-year-old man with lupus vulgaris who experienced a paradoxical deterioration of cutaneous lesions after starting antituberculosis therapy. The reaction was self-limiting; the lesions gradually improved, and the final outcome was very good. Paradoxical reactions are well-known in patients with human immunodeficiency virus (HIV) infection who start antiretroviral therapy, but they can also occur in non-HIV-infected patients with tuberculosis who start antituberculosis therapy. In the literature reviewed, paradoxical reactions involving skin lesions were described in patients with miliary tuberculosis. The case we report is the first of a paradoxical reaction in lupus vulgaris. The increasing frequency of tuberculosis in Spain could lead to a rise in the number of paradoxical reactions.

    A 61-year-old man living in rural Rwanda presented with a 2-month history of fevers, headaches, dry cough, weight loss and confusion. A cerebrospinal fluid analysis revealed neutrophilic pleocytosis, yeast and a positive cryptococcal antigen (CrAg). An HIV antibody test was negative. The patient's cough worsened while on antifungal induction therapy with intravenous conventional amphotericin B and high-dose oral fluconazole. Computerised tomography (CT) scan of the chest showed extensive miliary infiltrates. Bronchoalveolar lavage revealed acid-fast bacilli on smear and a positive GeneXpert test without rifampicin resistance. The patient improved with the addition of antitubercular therapy. In this case report, we describe an unusual presentation of two opportunistic infections occurring together in an HIV-negative man with no other known immunocompromising conditions. The case highlights the fact that, in disease endemic areas, multiple disseminated infections can occur in individuals without obvious immunocompromise.

    We reported three cases of acute intracranial tuberculosis including miliary tuberculosis, basal meningitis, tuberculomas and neuritis of cranial nerves. All patients had native and contrast enhanced CT and MRI scans. MRI revealed more granulomas and a better imaging contrast in the detection of basal meningitis. Neuritis was diagnosed only with the MRI. MRI scans should be prefered as the imaging procedure in clinically presumed intracranial tuberculosis. (orig.)

Sowohl die MRT als auch die CT wurden nativ und nach Kontrastmittelgabe durchgefuehrt. Die MRT zeigte sich im Nachweis von Granulomen insbesondere im Bereich des Hirnstamms ueberlegen. Ebenso wurde ein hoeherer Bildkontrast bei der Darstellung der Meningitis beobachtet. Eine Neuritis der Hirnnerven war nur mit der MRT nachweisbar.

    Full Text Available The gall bladder is least common intraabdominal organ to be involved by tuberculosis. It is either part of systemic miliary tuberculosis or abdominal tuberculosis. Isolated gall bladder tuberculosis is even rarer, can presents either as calculus or acalculus cholecystitis. Gall bladder tuberculosis presenting as a localized perforation with a sinus formation into anterior abdominal wall is unreported complication in a non immuno-compromised person. A 48-year old female presented with a gradually increasing swelling in right hypochondrium. Abdominal ultrasound showed superficial collection over right hypochondrium with intraperitoneal extension. Computed tomography showed localized gall bladder perforation with extension to the abdominal wall. Patient underwent emergency exploration and cholecystectomy with excision of sinus tract and drainage of abdominal wall abscess. Histopathological examination showed granulomatous cholecystitis suggestive of tuberculosis of gall bladder with extension into the sinus tract. She had an uneventful recovery and was treated with 6-month antitubercular therapy after surgery.

    Tuberculosis is an infectious disease and becomes a major threat all over the world but still diagnosis of tuberculosis is a challenging task. In literature, chest radiographs are considered as most commonly used medical images in under developed countries for the diagnosis of TB. Different methods have been proposed but they are not helpful for radiologists due to cost and accuracy issues. Our paper presents a methodology in which different combinations of features are extracted based on intensities, shape and texture of chest radiograph and given to classifier for the detection of TB. The performance of our methodology is evaluated using publically available standard dataset Montgomery Country (MC) which contains 138 CXRs among which 80 CXRs are normal and 58 CXRs are abnormal including effusion and miliary patterns etc. The accuracy of 81.16% was achieved and the results show that proposed method have outperformed existing state of the art methods on MC dataset.

    In marine organisms the multi xenobiotic resistance (MXR) mechanism via e.g. P-glycoprotein (P-gp) and multidrug resistance-associated protein (MRP) is an important first line of defense against contaminants by pumping contaminants out of the cells. If compounds would impair the MXR mechanism, this could result in increased intracellular levels of other compounds, thereby potentiating their toxicity. A calcein-AM based larval cellular efflux pump inhibition assay (CEPIA) was developed for echinoid (Psammechinus miliaris) larvae and applied for several contaminants. The larval CEPIA revealed that triclosan (TCS) and the nanoparticles P-85(®) (P-85) were 124 and 155× more potent inhibitors (IC(50) 0.5 ± 0.05 and 0.4 ± 0.1 μM, respectively) of efflux pumps than the model inhibitor Verapamil (VER). PFOS (heptadecafluorooctane sulfonic acid) and pentachlorophenol also were more potent than VER, 24 and 5×, respectively. Bisphenol A and o,p'-dichlorodiphenyltrichloroethane (o,p'-DDT) inhibited efflux pumps with a potency 3× greater than VER. In a 48 h early life stage bioassay with P. miliaris, exposure to a non-lethal concentration of the inhibitors TCS, VER, the model MRP inhibitor MK-571, the nanoparticles P-85 and the model P-gp inhibitor PSC-833, increased the toxicity of the toxic model substrate for efflux pumps vinblastine by a factor of 2, 4, 4, 8 and 16, respectively. Our findings show that several contaminants accumulating in the marine environment inhibit cellular efflux pumps, which could potentiate toxic effects of efflux pumps substrates.

    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.

    Despite significant conservation intervention, the kiwi (Apteryx spp.) is in serious population decline. To increase survival in the wild, conservation management includes rearing of young birds in captivity, safe from introduced mammalian predators. However, an increase in density of immunologically naïve kiwi increases the risk of exposure to disease, including coccidia. Intestinal coccidiosis has recently been described in the kiwi, and although extra-intestinal coccidiosis was first recognized in kiwi in 1978, very little is known about this disease entity. This study used archived histological tissues and reports from routine necropsies to describe the pathology of naturally occurring extra-intestinal coccidiosis. At least 4.5% of all kiwi necropsied during 1991 to 2011 (n=558) were affected by extra-intestinal coccidiosis, and it is estimated that it caused death in 0.9 to 1.2% of kiwi in the study group. Four forms were recognized: renal, hepatic, and, less commonly, splenic and pulmonary. At necropsy, renal coccidiosis was associated with miliary white streaks and foci through the kidneys, renomegaly, and renal pallor or congestion. Renal meronts and gametocytes were confined to the distal convoluted tubules and collecting ducts, and were associated with renal tubular necrosis and tubular obstruction. Hepatic miliary pinpoint foci were present throughout the hepatic parenchyma associated microscopically with macromeronts measuring 304×227 µm. In two cases, clusters of splenic meronts were identified, and a similar lesion was identified in the pulmonary interstitium of another case. Juvenile, captive kiwi were most often affected with extra-intestinal coccidiosis, illustrating an increased expression of disease with population manipulation for conservation purposes.

    Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei (PM) infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100%) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66%) had skin rashes; 8 cases (66%) had hepatomegaly; 9 cases (75%) had splenomegaly while 8 cases (66%) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes <50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of "cakes".

  7. Exposure to 2,4-decadienal negatively impacts upon marine invertebrate larval fitness.

    Diatoms liberate volatile, biologically active unsaturated aldehydes following cell damage, which negatively impact upon invertebrate reproductive processes such as fertilization, embryogenesis and larval survival. 2,4-Decadienal is frequently identified among the aldehydes produced and is one of the more biologically active. The majority of studies which have examined the toxic effects of diatom aldehydes to invertebrate reproduction have scored egg production and/or hatching success as indicators of biological impacts. There are very few studies which have dealt specifically with the impacts of diatom-derived aldehydes on larval fitness. Larval stages of the polychaetes Arenicola marina and Nereis virens and the echinoderms Asterias rubens and Psammechinus miliaris exposed to 2,4-decadienal at sub 1 microg ml(-1) concentrations suffered reduced survival over the incubation period (day 1-8 post fertilization) with detectable differences for the polychates at a concentration of 0.005 and 0.01-0.1 microg ml(-1) for the echinoderms. Susceptibility of larval N. virens was investigated using stage specific 24 h exposures at 2,4-decadienal concentrations up to 1.5 microg ml(-1). A clear stage specific effect was found, with earlier larval stages most vulnerable. Nectochaete larvae (9-10 d) showed no reduction in survival at the concentrations assayed. Fluctuating asymmetry (FA), defined as random deviations from perfect bilateral symmetry, was used to analyse fitness of larval P. miliaris exposed to 2,4-decadienal at concentrations of 0.1, 0.5 and 1 microg ml(-1). The degree and frequency of asymmetrical development increased with increasing 2,4-decadienal concentration. Equally, as FA increased larval survival decreased. These results provide further support for the teratogenic nature of 2,4-decadienal and its negative impact on invertebrate larval fitness.

    Dermatophytosis is among the most common superficial mycoses in Iran. The purpose of this report was to update the clinical and mycological features of human dermatophytosis in the Khuzestan, southwestern Iran. In the framework of a one-year survey, a total of 4120 skin, hair and nail samples obtained from the outpatients with symptoms suggestive of tinea were analyzed by using direct microscopy, culture and molecular identification methods. Strains isolated from cultures were subjected to amplification of the nuclear rDNA ITS regions in a PCR assay followed by an early established RFLP analysis. For confirmation of species identification, 100 isolates as representatives of all presumable species were subjected to ITS sequencing. Infection was confirmed in 1123 individuals (27.25 %) in the age range of 1-89 years by direct microscopy and/or culture including 603 males versus 520 females. Frequencies of infections were the highest and the lowest in age groups of 21-30 and 11-20 years, respectively. Tinea corporis was the most prevalent clinical manifestation followed by tinea cruris, tinea capitis, tinea manuum, tinea pedis, tinea unguium, tinea faciei and tinea barbae. Trichophyton interdigitale (58.7 %) was the most dominant isolate followed by Epidermophyton floccosum (35.4 %), Microsporum canis (3 %), T. rubrum (1.5 %), T. species of Arthroderma benhamiae (0.5 %), T. tonsurans (0.3 %) and T. violaceum (0.3 %). Other species included M. gypseum, M. fulvum and T. verrucosum (each one 0.1 %). Such a high occurrence of infection with T. interdigitale, which has not been reported from Iran, is due to the use of accurate molecular methods based on new species concept in dermatophytes. The prevalence of dermatophytoses caused by zoophilic species remarkably increased and Trichophyton species of A. benhamiae has emerged as a new agent of dermatophytosis in southwestern Iran, while infections due to anthropophilic species, except E. floccosum, took a

    To prevent the global spread of tuberculosis (TB), more effective vaccines and vaccination strategies are urgently needed. As a result of the success of bacillus Calmette-Guérin (BCG) in protecting children against miliary and meningeal TB, the majority of individuals will have been vaccinated with BCG; hence, boosting BCG-primed immunity will probably be a key component of future vaccine strategies. In this study, we compared the ability of DNA-, protein- and lentiviral vector-based vaccines that express the antigens Ag85B and Rv3425 to boost the effects of BCG in the context of immunity and protection against Mycobacterium tuberculosis in C57BL/6 mice. Our results demonstrated that prime-boost BCG vaccination with a lentiviral vector expressing the antigens Ag85B and Rv3425 significantly enhanced immune responses, including T helper type 1 and CD8(+) cytotoxic T lymphocyte responses, compared with DNA- and protein-based vaccines. However, lentivirus-vectored and DNA-based vaccines greatly improved the protective efficacy of BCG against M. tuberculosis, as indicated by a lack of weight loss and significantly reduced bacterial loads and histological damage in the lung. Our study suggests that the use of lentiviral or DNA vaccines containing the antigens Ag85B and Rv3425 to boost BCG is a good choice for the rational design of an efficient vaccination strategy against TB.

    Full Text Available In cats, the most common eosinophilic dermatoses are feline miliary dermatitis and eosinophilic granuloma complex. The most commonly identified underlying cause is a hypersensitivity reaction. Few cases of familial forms of eosinophilic dermatoses are reported in the literature. Two young adult cats from the same litter presented 2 years apart with a severe and chronic fluid or tissue infiltration of the distal part of several limbs. Lesions started on the forelegs and developed on the other limbs. Cytological and histopathological examinations showed lesions consistent with an atypical form of feline eosinophilic dermatosis associated with secondary bacterial infection. In both cats, antibiotics combined with immunosuppressive treatment partially improved the lesions, which continued to progress on a waxing and waning course, even in the absence of treatment. Allergy work-up did not permit the identification of an underlying allergic triggering factor. The severity of the lesions, the unusual presentation and the unsatisfactory response to immunosuppressive therapy in two feline littermates suggested a genetic form of eosinophilic dermatosis.

    Hypersensitivity dermatitides (HD) are commonly seen in cats, and they are usually caused by environmental, food and/or flea allergens. Affected cats normally present with one of the following clinical reaction patterns: head and neck excoriations, usually symmetrical self-induced alopecia, eosinophilic skin lesions or miliary dermatitis. Importantly, none of these clinical presentations is considered to be pathognomonic for HD skin diseases, and the diagnosis of HD is usually based on the exclusion of other pruritic diseases and on a positive response to therapy. The objectives of this study were to propose sets of criteria for the diagnosis of nonflea-induced HD (NFHD). We recruited 501 cats with pruritus and skin lesions and compared clinical parameters between cats with NFHD (encompassing those with nonflea, nonfood HD and those with food HD), flea HD and other pruritic conditions. Using simulated annealing techniques, we established two sets of proposed criteria for the following two different clinical situations: (i) the diagnosis of NFHD in a population of pruritic cats; and (ii) the diagnosis of NFHD after exclusion of cats with flea HD. These criteria sets were associated with good sensitivity and specificity and may be useful for homogeneity of enrolment in clinical trials and to evaluate the probability of diagnosis of NFHD in clinical practice. Finally, these criteria were not useful to differentiate cats with NFHD from those with food HD.

    Folliculitis et perifolliculitis capitis abscedens et suffodiens is a rare disease of unknown etiology. It is a suppurative process that involves the scalp, eventually resulting in extensive scarring and irreversible alopecia. The condition is also known as 'acne necrotica miliaris' or 'Proprionibacterium' folliculitis. Most often the disease affects men of African-American or African-Caribbean descent between 20 and 40 years of age. The clinical picture is determined by fluctuating painful fistule-forming conglomerates of abscesses in the region of the occipital scalp. The cause of scalp folliculitis is not well understood. It is generally considered to be an inflammatory reaction to components of the hair follicle, particularly the micro-organisms. These include: bacteria (especially Propionibacterium acnes, but in severe cases, also Staphylococcus aureus), Yeasts (Malassezia species) and mites (Demodex folliculorum). The initial histopathologic finding is an exclusively neutrophilic infiltration followed by a granulomatous infiltrate. The treatment of the disease is usually difficult and often disappointing. Successful treatment with isotretinoin 1 mg/kg body mass could be achieved only after regular systematic administration in the course of 3-4 months. Here we describe a patient with eruptive purulent form of the disease, which has been controlled with combination therapy: systemic antibiosis with metronidazole and clindamycin, dermatosurgical removal of single nodular formations, and isotretinoin 1 mg/kg body mass for 3-5 months.

    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.

    Hypersensitivity dermatitides (HD) are often suspected in cats. Cats with HD are reported to present with one or more of the following patterns: miliary dermatitis, eosinophilic dermatitis, self-induced symmetrical alopecia or head and/or neck excoriations. Previous reports on feline HD included small numbers of animals, took place in geographically restricted areas or did not compare these conditions with other causes of pruritus. The goal of the present study was to analyse 72 parameters covering signalment, clinical, laboratory and treatment characteristics from a large group of pruritic cats from different geographical areas. Of the 502 cats, the following diagnoses were made: flea HD (29% of cases), food HD (12%) nonflea/nonfood HD (20%) and other diseases in which pruritus was a feature (24%). Cats with signs consistent with a HD but which did not complete a food trial were not analysed further (15% of cases). Most cats with nonflea HD exhibited signs compatible with one or more of the four typical lesional patterns, but none of these patterns was found to be pathognomonic for any specific diagnosis. Food HD and nonflea/nonfood HD were found to be clinically undistinguishable. Young adult, purebred and female cats appeared predisposed to nonflea/nonfood HD. As many diagnoses presented with similar lesional patterns, a thorough clinical work-up is required for establishment of a specific diagnosis.

    Full Text Available Lo spettacolo teatrale The Rocky Horror Show (1973 di Richard O’Brien e, successivamente, l’adattamento cinematografico The Rocky Horror Picture Show (1975 di Jim Sharman possono essere considerate due pietre miliari del musical. Per temi e struttura, essi rappresentano la massima espressione della rivoluzione sessuale che va a cavalli tra gli anni '60 e '70 ed emblema del movimento di libertà sessuale. Il successo del musical risiede nella presa in giro degli stereotipi del gotico sia letterario che cinematografico, creando una enorme, irriverente parodia. Se il riferimento più evidente è il Frankenstein di Mary Shelley e la versione cinematografica di James Whale, meno analizzato è il rapporto con Benighted (1927 by John B. Priestley e la pellicola The Old Dark House (1932 sempre di Whale e adattata dal romanzo di Priestley. Proprio questa risulta, infatti, vera fonte di ispirazione per il lavoro di O’Brien, piuttosto che il Frankestein. Il contributo analizzerà questo rapporto, focalizzando la sua attenzione sugli elementi della “liturgia del Rocky Horror Show”, sui riferimenti in parodia e proponendo una visione dell’opera di O’Brien come una meta-aprodia.

    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.

    A total of 5,758 tuberculosis cases were notified in France in 2008, giving a rate of nine cases per 100,000 inhabitants. The median age was 45 years and 59% of cases were male patients. Île-de-France (Paris and greater Paris area) and French Guiana had the highest notification rate in 2008 (17.9/10(5) and 22.6/10(5) respectively). The rate of tuberculosis was higher in individuals born abroad (43.2/10(5) vs. 5.0/10(5) for individuals born in France), especially those recently arrived in France. Pulmonary tuberculosis accounted for 72% of notified cases, 76% of which were potentially contagious (positive sputum smear, or culture). Compared to 2007, the number of notified tuberculosis cases increased by 3.3% in 2008. This increase was not accompanied by a rise of severe cases (meningitis and miliary TB); this seemed to be due partly to improvement in identification and notification of cases. However this trend could require specific monitoring in future years. A national tuberculosis control program was launched in France in 2007, aiming at reducing epidemiological disparities. Clinical and public health expertise needs to be maintained on all the territory to ensure that implemented measures can have the expected impact on the epidemiology of the disease.

    Frogs of the genus Thoropa comprise six endemic Brazilian species on the Eastern side of the country. Little is known about their natural history, especially about their acoustic communication. Therefore, aiming to provide an overview of their vocalizations, we analyzed and redescribed male advertisement calls of three living and two possibly extinct species. The smaller species, T. petropolitana and T. lutzi, produce simple calls (one single note) with a higher frequency range than the remaining larger ones. On the other hand, the larger species present complex calls, with more than one note: T. megatympanum calls have three notes, T. taophora calls have four notes, and T. miliaris calls varies from three to six notes. Population snout-vent length negatively correlated with peak of dominant frequency as expected. However, highlighted differences between two populations of T. lutzi, which could indicate need of further taxonomic evaluation of those lineages. Peculiar morphology, such as the absence of vocal sacs and slits, may have contributed to their call variation and highly banded frequency structure. If the observed population differences reflect species-level differences, T. lutzi may be classified as a critically endangered species, as T. petropolitana. Furthermore, we provided a suggestion to an unusual behavior in frogs: calling with the mouth open in the smaller species of the genus. PMID:27617833

    We analyzed the acute phase radiographs of 107 consecutive patients with clinically confirmed extrinsic allergic alveolitis. Three readers independently recorded the profusion and the type of opacities according to the standard ILO criteria extended with categories x, y, z, and ground glass for description as proposed by McLoud et al. The profusion of the changes was grade 0 in 13%, grade 1 in 37%, grade 2 in 35%, and grade 3 in 15% of the interpretations. The type of predominant small opacities was p in 33%, x in 22%, s in 13%, t in 10%, q in 9%, and 0, r, u, y, and z in 13% of the interpretations. Ground glass density was seen in 8% of the recordings. The changes were predominantly located in the middle and lower lung zones. For comparison, according to the classification of Hapke et al. miliary changes (68%) predominated over fibrotic (27%) and normal (11%) recordings. The intraobserver agreement was good by both methods, but there was less interobserver variation with the ILO method. The semiquantitative standardized modified ILO scheme was considered more informative than Hapke's descriptive classification for epidemiologic and research purposes.

    The classification of an unexpected infant death as the sudden infant death syndrome (SIDS) depends upon a complete autopsy and death scene investigation to exclude known causes of death. Here we report the death of a four-month-old infant in a tuberculosis endemic area that presented as a sudden unexpected death in infancy (SUDI) with no apparent explanation based on the death scene characteristics. The autopsy, however, revealed progressive primary pulmonary tuberculosis with intrathoracic adenopathy, compression of the tracheobronchial tree and miliary lesions in the liver. This case underscores the clinical difficulties in the diagnosis of infantile tuberculosis, as well as the possibility of sudden death as part of its protean manifestations. The pathology and clinical progression of tuberculosis in infants differs from older children and adults due to the immature immune response in infants. This case dramatically highlights the need for complete autopsies in all sudden and unexpected infant deaths, as well as the public health issues in a sentinel infant tuberculosis diagnosis.

    Full Text Available A survey to determine the prevalence of bovine tuberculosis caused by Mycobacterium bovis and certain other infectious diseases was conducted on 42 free-ranging African buffaloes, (Syncerus caffer from May to June 1997 in the Queen Elizabeth National Park, Uganda. Using the gamma interferon test, exposure to M. bovis was detected in 21.6 % of the buffaloes. One dead buffalo and an emaciated warthog (Phacochoerus aethiopicus that was euthanased, were necropsied; both had miliary granulomas from which M. bovis was isolated. None of the buffaloes sampled in Sector A of the park, which has no cattle interface, tested positive for bovine tuberculosis (BTB exposure. The prevalence and distribution of BTB does not appear to have changed significantly since the 1960s, but this may be due to fluxes in the buffalo population. Serological testing for foot-and-mouth disease (FMD demonstrated positive exposure of 57.1% of the buffaloes sampled, with types A, O and SAT 1-3, which is the first known report of FMD antibodies to A and O types in free ranging African buffaloes. Foot-and-mouth disease virus types SAT 1 and SAT 3 were isolated from buffalo probang samples. Two percent of the buffaloes had been exposed to brucellosis. None of the buffaloes tested had antibodies to rinderpest, leptospirosis or Q fever.

    Full Text Available Introduction: BCG vaccine has shown consistently high efficacy against childhood tubercular meningitis and miliary tuberculosis and other mycobacterial diseases. It is considered to be a safe vaccine with a low incidence of adverse effects. Efficacy of BCG vaccine found in different clinical trials is variable in different geography. Objectives: Study was done to assess the efficacy of BCG vac-cine. Materials and Methods: All the children who were less than three years of age and were previously BCG vaccinated and not-vaccinated, were included in this study. A total of sixty (60 vaccinated children and sixty non-vaccinated children were selected. These children were followed up prospectively for 24 months, at the end of which, it was seen whether they developed tuberculosis or not. Results: Out of these 60 children in both the cases and control groups, total number of BCG vaccinated children who developed TB were 4 (i.e. 6.6% and total number of Non-BCG vaccinated children who developed TB were 12 (i.e. 20%. Thus, the efficacy of BCG vaccine calculated in our study was 67%. Conclusion: Most studies in different parts of the world have shown that the efficacy of BCG vaccine varies from zero to eigh-ty percent. This study favors the efficacy of BCG vaccine. This vaccination strategy will be favorable for our children. Creation of awareness among the parents and family members for an early administration of BCG vaccine after child birth can be recom-mended.

    A 41-year-old male patient was admitted in our Ryukyu University Hospital complaining of parosmia. He had a history of miliary tuberculosis 21 years ago. Neurologically he showed left anosmia and hyperreflexia of the right upper extremity. Plain skull X-P and CT scan revealed a calcified mass, 25 mm in diameter, at the left frontal base. In MRI, the mass showed isointensity using the T/sub 1/ weighted inversion recovery sequence and heterogenously low intensity using the T/sub 2/ weighted spin echo sequence. Surgery was performed by bifrontal craniotomy. Then the tumor was removed totally including two coexisting small tumors. Histologically, they consisted of calcified caseous tissue and thick collagen capsule, suggesting old calcified tuberculomas. Postoperative course was uneventful and did not result in meningitis. Antituberculous therapy of streptmycin, isoniazid and rifapicin was given for 2 weeks, started on the operative day. MRI findings were presented in detail and the guideline of antituberculous therapy to the tuberculoma was discussed.

    CT is a valuable method in determining number, location and extent of lesions, although a definite diagnosis is often not possible on CT. In intracranial tuberculosis, CT was helpful in the diagnosis, assessing the degree of hydrocephalus and evaluating the effectiveness of antituberculous therapy. Twenty-one cases of clinically proven intracranial tuberculosis were studied by CT in our hospital during last 3 years. Of them, eighteen cases were tuberculous meningitis and the rests were tuberculoma. The results were as follows: 1. Tuberculous meningitis presented the following three patterns of CT findings according to its disease process. a. In early stage of the disease, suspicious multiple isodense small nodules in the cerebral and cerebellar hemispheres showed dense enhancement in postcontrast scan representing miliary tubercles. b. In later stage of the disease, precontrast scan showed partial or total obliteration of the basal and sylvian cisterns with mild dilatation of ventricular system. Postcontrast scan showed dense enhancement of basal and sylvian cisterns. This type of finding was the most common in our series. c. Moderate to marked dilatation of ventricle with or without a cluster of calcifications in suprsella area on precontrast scan was seen in far later stage of as a sequellae of the disease. No enhancement was noted in postcontrast study. 2. Tuberculoma showed an isodense or slightly hyperdense area in the cerebral or cerebellar hemisphere with associated minimal edema in precontrast study. Postcontrast scan showed a small ring enhancement with central lucent area.

    Full Text Available Abstract. Tuberculous meningitis (TBM is a devastating disease. TBM occurs more commonly in HIV infected patients. The influence of HIV co-infection on clinical manifestations and outcome of TBM is not well defined. Yet, some differences have been observed and stroke has been recorded to occur more frequently. This study reports on an HIV infected Caucasian female with lung, meningeal tuberculosis and stroke due to a cortical sub-cortical ischemic lesion.TBM was documented in the absence of neurologic symptoms. At the same time, miliary lung TB caused by multi-susceptible Mycobacterium tuberculosis was diagnosed. Anti-TB therapy consisting of a combination of four drugs was administered. The patient improved and was discharged five weeks later. In conclusion, TBM and multiple underling pathologies including HIV infection, as well as other risk factors can lead to a greater risk of stroke. Moreover, drug interactions and their side effects add levels of complexity. TBM must be included in the differential diagnosis of HIV infected patients with stroke and TBM treatment needs be started as soon as possible before the onset of vasculopathy.

    Full Text Available Perinatal tuberculosis (TB is rarely reported, because the clinical manifestations are not specific and there is a problem in its laboratory and radiology examination which caused undiagnosed. Perinatal TB is the preferred description that encompasses TB acquired either intra uterine, during or post delivery in early newborn period. A-3- month old baby was transferred to Pediatric Emergency Hasan Sadikin Hospital because of prolong fever and unable to breastfeed. There was no problem with delivery. Lethargic, fever, tachypnea, and hepatosphlenomegali were found on physical examination. Ziehl Neelsen smear of gastric lavage yielded positive acid fast bacilli. Tuberculine test was non reactive, chest x-ray showed a miliary pattern, and cerebral spinal fluid analysis gave tuberculous meningitis interpretation. By active finding, his father and grandfather were detected as a source of TB transmission. In additon to oral antituberculosis regimen, antibiotics and prednison were also given. Septic shock and disseminated intravascular coagulation were occurred during his illness and the baby died. Staphylococcus haemolyticus was identified from blood culture. In conclusion, although there were no problems during labor, active investigation of perinatal TB possibility is required on the family with a source of TB. Caution on TB in pregnant women is necessary at developing country with high rates of TB.

  12. Immune Vulnerability of Infants to Tuberculosis

    2013-01-01

    Full Text Available One of the challenges faced by the infant immune system is learning to distinguish the myriad of foreign but nonthreatening antigens encountered from those expressed by true pathogens. This balance is reflected in the diminished production of proinflammatory cytokines by both innate and adaptive immune cells in the infant. A downside of this bias is that several factors critical for controlling Mycobacterium tuberculosis infection are significantly restricted in infants, including TNF, IL-1, and IL-12. Furthermore, infant T cells are inherently less capable of differentiating into IFN-γ-producing T cells. As a result, infected infants are 5–10 times more likely than adults to develop active tuberculosis (TB and have higher rates of severe disseminated disease, including miliary TB and meningitis. Infant TB is a fundamentally different disease than TB in immune competent adults. Immunotherapeutics, therefore, should be specifically evaluated in infants before they are routinely employed to treat TB in this age group. Modalities aimed at reducing inflammation, which may be beneficial for adjunctive therapy of some forms of TB in older children and adults, may be of no benefit or even harmful in infants who manifest much less inflammatory disease.

    Computed tomography is a very valuable method by which the pathogenic evolution of tuberculous meningitis may be followed, thereby facilitating its differential diagnosis and controlling the efficiency of therapy. The initial miliary tuberculosis in the brain, very often unaccompanied by neurological symptoms, may offer very evident CT images. CT may also demonstrate the fibrogelatinous exudate which fills the basal cisterns and surrounds the arterial vessels which cross this region. Because of this, secondary arteritis is frequent and may be indirectly detected by CT in the form of foci of ischemic infarcts. Tuberculomas may be multiple, and are found equally in the cerebral and the cerebellar parenchyma. These tuberculomas present different images on CT, depending on the evolution of the disease at that moment. Hydrocephalus is a common complication of TM and is caused by a lack of reabsorption of the cerebrospinal fluid, or by an obstructive lesion in the ventricular drainage pathways due to a tuberculoma. This complication is usually easily identified by CT, which, moreover, permits the control of its evolution.

    Two siblings, a 6-month-old sexually intact male weighing 2.5 kg (cat 1) and a sexually intact female (cat 2) British Shorthair cat weighing 2.3 kg, were examined because of a 3-week history of polyuria, lethargy and laboured breathing. One year previously, another sibling (cat 3) had been presented because of similar, yet more severe, clinical signs at the age of 5 months. Physical examination revealed lethargy, dehydration and polypnoea with slightly increased inspiratory effort. Diagnostic investigation revealed severe hypercalcaemia (cats 1-3), renal azotaemia (cats 1 and 3) and a radiologically generalised miliary interstitial pattern of the lungs (cats 1-3) attributable to hypervitaminosis D caused by ingestion of commercial cat food. Cat 3 was euthanased. Cats 1 and 2 were treated with isotonic saline solution (180 ml/kg IV daily), sucralfate (30 mg/kg PO q12h), terbutaline (only cat 1: 0.1 mg/kg SC q4h), furosemide (1.5 mg/kg IV q8h) and tapering doses of prednisolone. Cat 2 was normal on day 14. Cat 1 had stable renal disease and was followed up to day 672. The radiological generalised military interstitial pattern of the lungs had improved markedly. Excessive cholecalciferol-containing commercially available cat food poses a great hazard to cats. Supportive treatment may result in long-term survival and improvement of radiological pulmonary abnormalities.

    A loggerhead sea turtle (Caretta caretta) was found stranded alive along the Adriatic coast close to Ancona, Italy, displaying obtundation, tachypnea, and increased respiratory effort. It died a few hours after admission, and a postmortem examination was immediately performed. Miliary yellowish nodules were evident in the liver, and a lower number in the heart, stomach, and gut wall. Hundreds of whitish nodules were scattered in the lungs, with the majority of the pulmonary parenchyma being replaced by the lesions. Histologically, all nodular lesions consisted of a small central area of necrosis with acid-fast bacilli surrounded by epithelioid cells, macrophages, and lymphocytes. Giant cells were found in the spleen and the liver. Kidneys, lungs, liver, spleen, brain, and skin lesions were inoculated aseptically onto general isolation media and selective isolation media for mycobacteria. The isolate showed a restriction pattern identical to Mycobacterium chelonae by polymerase chain reaction-restriction fragment length polymorphism. To the best of the authors' knowledge, this is the first description of a disseminated infection caused by a potentially pathogenic mycobacteria in a stranded, free-ranging loggerhead sea turtle. Veterinary staff and biologists who handle sea turtles with suspected mycobacterial disease should protect themselves appropriately.

    Full Text Available Hydatid cyst and tuberculosis are common infectious diseases in our country. However, co-incidence of these two diseases is a rare case. This refers to spontaneous emergence of cyst hydatid and tuberculosis lesion in liver which is presented in this paper. Liver tuberculosis can be detected either as a component of miliary tuberculosis or isolated liver tuberculosis. Herein we report a case of 46 year-old male. He applied to the emergency due to the severe right-side pain which coupled with breathing and movement. This was reported to last for 10 days. Lesion compatible to cyst hydatid with a size of 151 x 144 x 128 mm was detected in the right lobe anterior in his abdomen ultrasonography. Echinococcus indirect hemagglutination test resulted in 1/640 positive. The patient had liver cystectomy by general surgery clinic. After microscopic examination of excision material, chronic granulomatous inflamation with caseous necrosis was detected in parenchyma to which cyst hydatid and lesion were attached. PPD result was 16 mm. The patient, whose lungs were normal, received antituberculosis treatment due to primary liver tuberculosis.

    Water soluble diatom extracts and the diatom aldehyde 2-trans,4-trans decadienal were assayed on the gametes and embryos of the broadcast spawning polychaetes Arenicola marina and Nereis virens and the echinoderms Asterias rubens and Psammechinus miliaris. Both crude cellular extracts and purified aldehyde were found to inhibit fertilization, embryogenesis and hatching success in a dose dependent manner. Intact diatom cells had no discernable effect on fertilization or development. Extracts of Skeletonema costatum were generally more effective than Nitzschia commutata in inhibiting development and fertilization. There was considerable interspecific variation in terms of toxin sensitivity. The polychaetes were more sensitive to the effects than the echinoderms. Within the polychaetes A. marina was the more tolerant in terms of developmental competence but N. virens had a higher fertilization rate. Echinoid embryos were more tolerant than asteroid embryos. This is the first study to present data on the inhibition of fertilization success by diatom extracts and aldehydes. Our observations are discussed in relation to temporal patterns in spawning and possible adaptive mechanisms to avoid diatom toxicity.

    Frogs of the genus Thoropa comprise six endemic Brazilian species on the Eastern side of the country. Little is known about their natural history, especially about their acoustic communication. Therefore, aiming to provide an overview of their vocalizations, we analyzed and redescribed male advertisement calls of three living and two possibly extinct species. The smaller species, T. petropolitana and T. lutzi, produce simple calls (one single note) with a higher frequency range than the remaining larger ones. On the other hand, the larger species present complex calls, with more than one note: T. megatympanum calls have three notes, T. taophora calls have four notes, and T. miliaris calls varies from three to six notes. Population snout-vent length negatively correlated with peak of dominant frequency as expected. However, highlighted differences between two populations of T. lutzi, which could indicate need of further taxonomic evaluation of those lineages. Peculiar morphology, such as the absence of vocal sacs and slits, may have contributed to their call variation and highly banded frequency structure. If the observed population differences reflect species-level differences, T. lutzi may be classified as a critically endangered species, as T. petropolitana. Furthermore, we provided a suggestion to an unusual behavior in frogs: calling with the mouth open in the smaller species of the genus.

    Demodex gatoi is a transmissible, short-bodied mite found in the stratum corneum of cats. It is known to cause moderate to intense pruritus, often manifested as self-induced alopecia and excoriations. 10% imidacloprid/1% moxidectin (a) is a monthly, topical solution indicated for the treatment and/or prevention of fleas, heartworms, intestinal parasites, and ear mites. A household of cats was presented for pruritus that ranged from mild to severe in 8 of the 13 felines. The most common clinical signs included miliary-type papular dermatitis and focal areas of erythema associated with alopecia. Multiple skin scrapings of each animal revealed Demodex gatoi mites in only two cats. Weekly topical administration of 10% imidacloprid/1% moxidectin was used on all cats in the household for a total of ten doses. Skin scrapings following treatment were negative, and all cats in the house improved. Based on the successful treatment of this small number of cats, weekly application of 10% imidacloprid/1% moxidectin should be considered for the clinical resolution of cats affected by D. gatoi.

    Five kudus (Tragelaphus strepsiceros), three bulls and two cows, within the Greater Kruger National Park complex, were diagnosed with generalized tuberculosis caused by Mycobacterium bovis. The lesions seen in these animals were similar to those previously reported in kudus and included severe tuberculous lymphadenitis of the nodes of the head and neck (that resulted in noticeable uni- or bilateral swelling beneath the ear), thorax, and the mesentery. All the animals also suffered from severe granulomatous pneumonia. The lesions in the lungs were more severe cranially and had a miliary distribution elsewhere in the lungs. Based on the DNA patterns of the M. bovis isolates, at least some of these kudus were infected with strains commonly present in tuberculous buffaloes, lions, cheetahs, and baboons in the Park whereas other strains from these kudus were quite different and may reflect another source of infection. The presence of tuberculous kudus in the Park is expected to complicate control measures that may be instituted to contain or eradicate the disease in the Park.

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

    Full Text Available Neonatal Bacille Calmette Guérin (BCG vaccination has been reported to have beneficial effects beyond preventing infantile tuberculous meningitis and miliary disease. We hypothesized that BCG vaccine given at birth would enhance T-helper 1 (Th1 immune responses to the first vaccines given later in infancy. We conducted a nested case-control study of neonatal BCG vaccination and its heterologous Th1 immune effects in 2–3 months old infants. BCG vaccination at birth was associated with an increased frequency of interferon-γ (IFN-γ producing spot-forming cells (SFC to tetanus toxoid 2–3 months later. The frequency of IFN-γ producing SFC to polioviruses 1–3 also trended higher among infants who received BCG vaccination at birth. The frequency of IFN-γ+/tumor necrosis factor-α (TNF-α+CD45RO+CD4+ T-cells upon stimulation with phorbol myristate acetate (PMA/Ionomycin was higher in 2–3 months old infants who received BCG vaccination at birth compared to those who did not. The circulating frequency of forkhead box P3 (FoxP3+ CD45RO+ regulatory CD4+ T-cells also trended lower in these infants. Neonatal BCG vaccination is associated with heterologous Th1 immune effects 2–3 months later.

    Full Text Available Background: Systemic sclerosis is a multi-systemic autoimmune disorder affecting predominantly the skin, lungs, gut and kidneys. Purpose: To report the increased incidence of tuberculosis in patients of systemic sclerosis on dexamethasone pulse (DP therapy. Methods: Forty-seven patients of systemic sclerosis were included in the study. After taking a complete history and doing a detailed physical examination, the patients were submitted to a battery of investigations including complete hemogram(CBC with erythrocyte sedimentation rate (ESR(F, Chest X-ray CXR (PA view Mantoux test and urine analysis. CBC, ESR and urine examination was done monthly and CXR were repeated six-monthly. Findings: Seven patients on DP therapy developed genitourinary tuberculosis. Four had pulmonary tuberculosis. One patient developed tubercular lymphadenitis, one patient succumbed to miliary tuberculosis. Conclusion: There is an increased incidence of tuberculosis amongst patients of systemic sclerosis on DP therapy. Limitation of the Study: There was no control group of systemic sclerosis patients not on DP therapy to rule out the confounding effect of the disease per se predisposing to tuberculosis as all our patients as a matter of routine were put on steroid pulse. Also, the increased incidence of tuberculosis was detected incidentally while on monthly follow-up.

    Haematogenous dissemination of undiagnosed urinary tuberculosis after performing extracorporeal shock-wave lithotripsy (ESWL) is extremely rare. Herein, we report a 41-year-old male who presented with urosepsis to the emergency room; catheterization was performed and retention resolved. He had a tattoo on his left arm and a five-year history of intravenous drug use. Blood tests indicated anaemia, leukocytosis, elevated CRP and ESR and mild hyponatraemia; haematuria, moderate bacteriuria and 2+ proteinuria on urinanalysis were observed. Chest X-ray revealed lesions suggestive of miliary tuberculosis, which was confirmed by chest CT scan. Brain CT and MRI suggested brain involvement in the setting of tuberculosis. On further investigations, HIV infection and hepatitis C seropositivity were detected and the patient remained in a coma for five days with a Glasgow Coma Scale of 6/15. Finally, the diagnosis of haematogenous dissemination of tuberculosis following lithotripsy was established. Anti-tuberculosis and anti-retroviral therapy were prescribed and monthly follow-up visits were scheduled. In conclusion, in a patient diagnosed with ureterolithiasis, a thorough history and physical examination, with specific attention to HIV and tuberculosis predisposing factors, should be carried out and preoperative screening tests considering the possibility of urinary tuberculosis are required. Finally, if urinary tuberculosis is detected, ESWL must be postponed until after appropriate treatment of tuberculosis.

    2013-08-10

    Mycobacterium tuberculosis (TB) is a major cause of death globally. TB is capable of infecting every organ in the body, and the heart is no exception. Tuberculous endocarditis (TBE) was first reported in 1892 and subsequently many other cases have been described, highlighting the significant morbidity and mortality associated with this manifestation of TB. TBE usually presents with miliary tuberculosis and most early cases were diagnosed on autopsy. With increasing application of prosthetic valve replacements in the treatment of infective endocarditis (IE), TB infections have begun to affect these as well as native valves. With the introduction of TB culture methods and drug therapy, the prognosis has improved. HIV and drug resistance are likely to make the management of TBE more difficult in the future. Large scale studies, both prospective and retrospective, are required to ascertain the true incidence of TBE whilst development of novel anti-TB therapy is also required to combat resistance. We present the first extensive literature review on TBE in over 75 years.

    Oceanic waters of the Northern Arabian Sea experience massive algal blooms during winter-spring (mid Feb-end Mar), which prevail for at least for 3 months covering the entire northern half of the basin from east to west. Ship cruises were conducted during winter-spring of 2001-2012 covering different stages of the bloom to study the biogeochemistry of the region. Phytoplankton analysis indicated the presence of green tides of dinoflagellate, Noctiluca scintillans (=N. miliaris), in the oceanic waters. Our observations indicated that diatoms are coupled and often co-exist with N. scintillans, making it a mixed-species ecosystem. In this paper, we describe an approach for detection of bloom-forming algae N. scintillans and its discrimination from diatoms using Moderate Resolution Imaging Spectroradiometer (MODIS)-Aqua data in a mixed-species environment. In situ remote sensing reflectance spectra were generated using Satlantic™ hyperspectral radiometer for the bloom and non-bloom waters. Spectral shapes of the reflectance spectra for different water types were distinct, and the same were used for species identification. Scatter of points representing different phytoplankton classes on a derivative plot revealed four diverse clusters, viz. N. scintillans, diatoms, non-bloom oceanic, and non-bloom coastal waters. The criteria developed for species discrimination were implemented on MODIS data and validated using inputs from a recent ship cruise conducted in March 2013.

    Feline and canine atopic dermatitis are thought to have a similar immunopathogenesis. As with dogs, detection of allergen-specific IgE in cat serum merely supports a diagnosis of feline atopy based on compatible history, clinical signs and elimination of other pruritic dermatoses. In this study, a rapid screening immunoassay (Allercept(®) E-Screen 2nd Generation; Heska AG, Fribourg, Switzerland; ES2G) was compared with a complete-panel serum allergen-specific IgE assay (Allercept(®); Heska AG; CP) in healthy cats with no history of skin disease and in atopic cats. The latter had no diagnosis of external parasitism, infection, food hypersensitivity or other skin disease explaining their pruritus, and expressed cutaneous reaction patterns typically associated with feline allergic skin disease (head, neck or pinnal pruritus, miliary dermatitis, self-induced alopecia, eosinophilic granuloma complex). The proportion of cats positive on either the ES2G or the CP assays was not significantly different between the atopic and healthy cat groups. There was, however, strong agreement between the results of the ES2G and CP assay; overall, the two tests were in agreement for 43 of 49 (88%) serum samples. There was also strong agreement when individual allergen groups were evaluated (agreement noted: indoor, 41 of 49 samples; grasses/weeds, 37 of 49 samples; and trees, 41 of 49 samples). These results indicate that although neither test is diagnostic for feline atopic dermatitis, the screening assay is beneficial for predicting the results of a complete-panel serum allergen-specific IgE assay in cats.

    Background Factors of cell-mediated immunity and allergy together play their roles in the pathogenesis of pulmonary tuberculosis (PTB) and its prognosis. The purpose of this study was to investigate the computed tomographic demonstrations of HIV seropositive PTB and the relationship between its pathogenesis and CD4+ T-lymphocyte count.Methods The documented CT images of a total of 44 patients with HIV seropositive PTB, definitely diagnosed by etiological or pathological examinations, their clinical data and their CD4+ T-lymphocyte count were retrospectively reviewed.Results There were 15 cases of miliary tuberculosis, accounting for 34.1% of the total cases; 15 cases of nodular tuberculosis, 34.1%; 6 cases of ground-glass opacity, 13.6%; 5 cases of cord-liked fiber shadows, 11.4%; 16 cases of flaky and flocculating shadows, 36.4%; 5 cases of cavitation, 11.4%; 5 cases of tumor shadows, 11.4%; 2 cases of pleural thickening, 4.5% and 11 cases of pleural effusion, 25.0%; 1 case of calcification, 2.3%; 16 cases of lymphadenectasis,36.4%. The foci were located around the pulmonary hilum, anterior segment of superior lobe, basal segment of inferior lobe, medial lobe and lingual lobe. CD4+ T-lymphocyte count was closely related to the imaging demonstrations of HIV seropositive PTB.Conclusions CT scanning can demonstrate various signs of PTB. CD4+ T-lymphocyte level determines the variety of imaging demonstrations of HIV seropositive PTB and its prognosis.

    Full Text Available The study was carried out in pulmonary tuberculosis (PTB patients from the local Tuberculosis control programme, Mumbai, India. It examined features of chest X-rays and their correlation with clinical parameters for possible application in suspected multidrug resistant TB (MDRTB and to predict outcome in new and treatment failure PTB cases. X-ray features (infiltrate, cavitation, miliary shadows, pleural effusion, mediastinal lymphadenopathy and extent of lesions were analyzed to identify associations with biological/clinical parameters through univariate and multivariate logistic regression. Failures demonstrated associations between extensive lesions and high glycosylated hemoglobin (GHb levels (P=0.028 and male gender (P=0.03. An association was also detected between cavitation and MDR (P=0.048. In new cases, bilateral cavities were associated with MDR (P=0.018 and male gender (P=0.01, low body mass index with infiltrates (P=0.008, and smoking with cavitation (P=0.0238. Strains belonging to the Manu1 spoligotype were associated with mild lesions (P=0.002. Poor outcome showed borderline significance with extensive lesions at onset (P=0.053. Furthermore, amongst new cases, smoking, the Central Asian Strain (CAS spoligotype and high GHb were associated with cavitation, whereas only CAS spoligotypes and high GHb were associated with extensive lesions. The study highlighted associations between certain clinical parameters and X-ray evidence which support the potential of X-rays to predict TB, MDRTB and poor outcome. The use of Xrays as an additional tool to shorten diagnostic delay and shortlist MDR suspects amongst nonresponders to TB treatment should be explored in a setting with limited resources coping with a high MDR case load such as Mumbai.

  17. [TUBERCULOSIS ANNUAL REPORT 2014--(1) Summary of Statistics on Tuberculosis Notification and Foreign-born Tuberculosis Patients].

    2016-02-01

    This brief is the first of a series of documents based on the Tuberculosis Annual Report 2014. It includes a summary of tuberculosis (TB) statistics, including data on foreign-born TB patients notified and registered in Japan in 2014. For the first time, the number of newly notified cases (all forms of TB) fell below 20,000. In 2014, a total of 19,615 patients were notified, a rate of 15.4 per 100,000 population The number of sputum-smear positive pulmonary. TB patients notified was 7,651, a rate of 6.0 per 100,000 population. The number of patients with latent TB infections increased slightly from 7,147 in 2013 to 7,562 in 2014. The proportion of miliary TB cases has constantly increased over the past 10 years, especially among women aged 80 years and older. The number of foreign-born TB patients continued to increase from 1,064 in 2013 to 1,101 in 2014. In 2014, new foreign-born TB patients aged 20-29 years accounted for 44.1% of all new TB patients in that age group. Among foreign-born TB patients, half were from the Philippines (26.5%) and China (23.5%). However, the number of patients from Vietnam and Nepal is increasing. Among foreign-born TB patients, 28% were regular employees, 26% were students, and 20% were unemployed. The changing trend in the nationality of foreign students entering Japan may at least partially explain the differences in TB burden among foreign-born patients, by country of birth. As we expect to see the proportion of foreign-born TB patients continue to rise, more tailored case identification and treatment support activities are needed.

  18. Did Jean-Martin Charcot contribute to stroke?

    Stroke was never identified as a significant, autonomous field of activity of the emerging school of neurology at La Salpêtrière, which developed after the appointment of Jean-Martin Charcot (1825-1893) during the last days of 1861. However, stroke was already present in Charcot's first paper (1851), which dealt with a case of multiple organ cardiac embolism, including middle cerebral artery infarction, at a time when the studies of Rudolf Virchow on thromboembolism were unknown in France. A few years later, Charcot made a still up-to-date description of vascular intermittent claudication, which had only been reported in the horse. In the 1860s, Charcot and his pupils presented several major works dealing with cerebrovascular disease, including famous studies on miliary aneurysms in cerebral hemorrhage. This work was done with Charles Bouchard, at the time Charcot's 'interne', but who would become one of his 'political' opponents 2 decades later, when in 1892, as president of the 'agrégation' jury, he rejected the professorship application of 4 protégés of Charcot, including Joseph Babinski and Georges Gilles de la Tourette. Further work on cerebrovascular disease by Charcot included histological studies of brain 'softening', paraneoplastic cerebral arterial occlusion and consequences of stroke (e.g. arthropathies, vegetative changes, contractures and abnormal movements). Brain localization, one of Charcot's major neurological topics, was also largely based on stroke case studies. Charcot's work on stroke remains poorly recognized, but it demonstrates his unique skills in stimulating scientific work in younger colleagues, many of whom subsequently became major figures of neurology and psychiatry.

    Full Text Available A forma clássica de apresentação da neurotuberculose é a meningite. Os tuberculomas cerebrais são formas raras de neurotuberculose e resultam da disseminação hematogênica de focos distantes de infecção pelo Mycobacterium tuberculosis. Aproximadamente 1% dos pacientes com tuberculose do sistema nervoso central desenvolve tuberculomas intracranianos, poucas semanas ou meses após o início da quimioterapia tuberculostática. A involução das lesões é lenta e não necessariamente significa resistência medicamentosa ou falta de aderência ao tratamento. Descrevemos o caso, diagnosticado e tratado na 25ª Enfermaria da Santa Casa da Misericórdia do Rio de Janeiro, de um paciente imunocompetente que apresentou meningite e tuberculomas múltiplos do sistema nervoso central, durante o tratamento específico de tuberculose miliar. A literatura é revisada e o diagnóstico, terapêutica e possíveis mecanismos imunológicos são discutidos.The classical presentation of neurotuberculosis is meningitis. Intracranial tuberculomas are a rare manifestation of neurotuberculosis and are due to hematogenous dissemination of distant focuses of Mycobacterium tuberculosis infection. Around 1% of patients with central nervous system tuberculosis develop intracranial tuberculomas some weeks or months after the beginning of the specific treatment with tuberculostatic chemotherapy. The involution of the lesions is slow and does not mean drug resistance nor lack of adequate treatment. We describe the case, diagnosed and treated at the 25th Infirmary of Santa Casa da Misericórdia do Rio de Janeiro, of an immunocompetent male patient who developed meningitis and multiple intracranial tuberculomas during the specific treatment of miliary tuberculosis. The literature is revised and the diagnosis, treatment and possible immunological mechanisms are discussed.

    Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.Apresentamos um paciente com tuberculose miliar a partir de um foco crônico urogenital. Em sua entrada no hospital tinha uma função renal limítrofe e desenvolveu franca insuficiência renal na vigência da terapêutica específica constituída por RMP, INH e EMB. Bióp-sia renal realizada no 3° dia de uremia revelou necrose tubular recente, com inflamação intersticial aguda, permeada por granulomas. As formações granulomatosas foram altamente sugestivas de reação alérgica à droga devido à ausência de paliçadas, alta incidência de neutrófilos e o não encontro de bacilos-álcool-ácido-resistentes. Esta é a primeira descrição de nefrite intersticial granulomatosa provavelmente causada pela RMP. São discutidos os principais aspectos fisiopatogênicos da insuficiência renal causada pela tuberculose acrescida dos efeitos nefrotóxicos da RMP.

    Full Text Available Globally, tuberculosis (TB still remains a major public health problem. India is a high TB burden country contributing to 26 per cent of global TB burden. During 1944-1980, TB became treatable and short-course chemotherapy emerged as the standard of care. When TB elimination seemed possible in the early 1980s, global human immunodeficiency virus (HIV infection/acquired immunodeficiency syndrome (AIDS pandemic resulted in a resurgence of TB. Widespread occurrence of multidrug-resistant and extensively drug-resistant TB (M/XDR-TB is threatening to destabilize TB control globally. Atypical clinical presentation still poses a challenge. Disseminated, miliary and cryptic TB are being increasingly recognized. Availability of newer imaging modalities has allowed more efficient localization of lesions and use of image guided procedures has facilitated definitive diagnosis of extrapulmonary TB. Introduction of liquid culture, rapid drug-susceptibility testing (DST, molecular diagnostic methods has helped in rapid detection, speciation and DST profiling of Mycobacterium tuberculosis isolates. While treatment of TB and HIV-TB co-infection has become simpler, efforts are on to shorten the treatment duration. However, drug toxicities and drug-drug interactions still constitute a significant challenge. Recently, there has been better understanding of anti-TB drug-induced hepatotoxicity and its frequent confounding by viral hepatitis, especially, in resource-constrained settings; and immune reconstitution inflammatory syndrome (IRIS in HIV-TB. Quest for newer biomarkers for predicting a durable cure, relapse, discovery/repurposing of newer anti-TB drugs, development of newer vaccines continues to achieve the goal of eliminating TB altogether by 2050.

    Full Text Available Abstract Background Due to the lack of specific clinical manifestations and imaging features, the diagnosis of pulmonary mycosis is difficult. This study aimed to investigate the pathogens, clinical manifestations, imaging features, diagnosis and management of pulmonary mycosis. Methods Data on 68 patients diagnosed as pulmonary mycosis in Xiang Ya hospital from January 2001 to December 2010 were collected and their clinical manifestations, radiographic characterization, diagnostic methods and management were analyzed. Results All patients were diagnosed by pathological examination. Of the 68 cases, 38 (55.9% had pulmonary aspergillosis and 19 (27.9% pulmonary cryptococcosis. Open-lung surgery was performed in 38 patients (55.9%, transbronchial biopsy in 15 (22.0%, and computerized tomography (CT guided percutaneous needle biopsy in 11 (16.2%. Main symptoms were as follows: cough in 51 cases (75.0%, expectoration in 38 (55.9%, hemoptysis in 25 (37.8%, fever in 20 (29.4%, while 6 cases (11.1% were asymptomatic. X-ray and chest CT showed masses or nodular lesions in 52 cases (76.5%, patchy lesions in 10 (14.7%, cavity formation in 15 (22.0%, and diffuse miliary nodules in 1 case. In 51 cases (75.0% misdiagnosis before pathological examination occurred. Surgical resection was performed in 38 patients (55.9%. In 25 patients (36.7% systemic antifungal therapy was administered, and 20 patients (29.4% experienced complete responses or partial responses. Conclusion The main pathogens of pulmonary mycosis are Aspergillus, followed by cryptococcosis. Final diagnosis of pulmonary mycosis mainly depends on pathological examination. The clinical manifestations, imaging features, diagnostic methods and management differ depending on the pathogens. Satisfactory therapy can be obtained by both antifungal and surgical treatment.

  3. Reducing the activity and secretion of microbial antioxidants enhances the immunogenicity of BCG.

    Directory of Open Access Journals (Sweden)

    Shanmugalakshmi Sadagopal

    Full Text Available BACKGROUND: In early clinical studies, the live tuberculosis vaccine Mycobacterium bovis BCG exhibited 80% protective efficacy against pulmonary tuberculosis (TB. Although BCG still exhibits reliable protection against TB meningitis and miliary TB in early childhood it has become less reliable in protecting against pulmonary TB. During decades of in vitro cultivation BCG not only lost some genes due to deletions of regions of the chromosome but also underwent gene duplication and other mutations resulting in increased antioxidant production. METHODOLOGY/PRINCIPAL FINDINGS: To determine whether microbial antioxidants influence vaccine immunogenicity, we eliminated duplicated alleles encoding the oxidative stress sigma factor SigH in BCG Tice and reduced the activity and secretion of iron co-factored superoxide dismutase. We then used assays of gene expression and flow cytometry with intracellular cytokine staining to compare BCG-specific immune responses in mice after vaccination with BCG Tice or the modified BCG vaccine. Compared to BCG, the modified vaccine induced greater IL-12p40, RANTES, and IL-21 mRNA in the spleens of mice at three days post-immunization, more cytokine-producing CD8+ lymphocytes at the peak of the primary immune response, and more IL-2-producing CD4+ lymphocytes during the memory phase. The modified vaccine also induced stronger secondary CD4+ lymphocyte responses and greater clearance of challenge bacilli. CONCLUSIONS/SIGNIFICANCE: We conclude that antioxidants produced by BCG suppress host immune responses. These findings challenge the hypothesis that the failure of extensively cultivated BCG vaccines to prevent pulmonary tuberculosis is due to over-attenuation and suggest instead a new model in which BCG evolved to produce more immunity-suppressing antioxidants. By targeting these antioxidants it may be possible to restore BCG's ability to protect against pulmonary TB.

    Full Text Available Tuberculous involvement of liver as a part of disseminated tuberculosis is seen in up to 50-80% cases, but localized hepatobiliary tuberculosis (HBTB is uncommonly described. During 6 years, a total of 280 consecutive patients with TB were evaluated prospectively for the presence and etiology of liver involvement. Cases with miliary TB or immunosuppression and cases receiving anti-tuberculosis drugs prior to presentation to our unit were excluded (38 cases. Details of clinical, biochemical and imaging findings and histology/microbiology were noted. Of 242 included cases, 38 patients (15.7%; age 38.1 ± 12.5 years; sex ratio 2.5:1 had HBTB, whereas 20 patients (9%; age 39.3 ± 16.3 years; sex ratio 2.1:1 had other liver diseases. Diagnosis of HBTB was based on caseating granuloma on histology (18/23 procedures, positive smear/culture for acid-fast bacilli (21/39 procedures and positive polymerase chain reaction for Mycobacterium tuberculosis (28/29 procedures when diagnostic procedures were guided by imaging results. Thirty-eight cases with HBTB were classified as follows [patients (n, (%]: (A hepatic TB [20 (52.6%]: (1 granulomatous hepatitis - 10 (26.3%, (2 liver abscesses or pseudotumors - 10 (26.3% and (3 calcified hepatic granuloma - 0 (0%; (B biliary TB [15 (39.4%]: (1 biliary strictures - 2 (5.2%, (2 gall bladder involvement - 1 (2.6% and (3 biliary obstruction due to lymph node masses - 12 (31.5%; (C mixed variety [3 (7.8%]: (1 simultaneous granulomatous hepatitis and biliary stricture - 1 (2.6% and (2 simultaneous lymph node involvement and calcified hepatic granuloma - 2 (5.2%. All the cases responded well to standard anti-tuberculosis therapy. HBTB forms an important subgroup in TB cases. It requires a combination of imaging, histological and microbiological procedures to define the diagnosis. HBTB responds well to treatment.

    The BCG vaccine was introduced in 1921 and remains the only licensed vaccine for the prevention of TB worldwide. Despite its extensive use, the BCG vaccine lacks the ability to fully control the TB-endemic and -pandemic situations. The BCG vaccine is most effective in preventing pediatric TB, in particular, miliary TB and tuberculous meningitis. However, it has a limited effect in preventing pulmonary TB, which occurs more frequently in adults. BCG vaccination has now been implemented in more than 157 countries worldwide. For various countries, the benefits of vaccination are only limited and potentially not cost effective. The International Union Against Tuberculosis and Lung Diseases had set the criteria for discontinuation of BCG vaccination in 1994. This decision, however, was not based on economic considerations. Many developed countries have met the criteria set by the International Union Against Tuberculosis and Lung Disease and stopped universal BCG vaccination. For developing countries, the BCG vaccine is still an effective intervention in protecting young children from TB infection. A lot of effort has been spent on R&D of new TB vaccines, the first of which are expected to be available within 5-7 years from now. Novel TB vaccines are expected to be better and more effective than the current BCG vaccine and should provide a viable strategy in controlling TB morbidity and mortality. In this review, the aim is to explore economic evaluations that have been carried out for vaccination against TB worldwide. In addition to epidemiological evidence, economic evidence can play a crucial role in supporting the governments of countries in making proper public health decisions on BCG vaccination policies, in particular, to implement, continue, or discontinue.

    Full Text Available Background: HIV/AIDS is a global disease and despite intensive research it is one of the main causes of human death. Postmortem studies have proven accurate in determining the various pathologies in these patients. Aims & Objectives: Our aim was to analyze the post mortem results of individuals who died after HIV infection in the same geographical region. We evaluated the most frequent opportunistic diseases and their clinical and morphological outcomes. Methods: We studied case reports and autopsy research data from 32 patients who died after HIV infection in Smolensk, Russian Federation, between 2003 and 2008. All patients had been diagnosed with HIV infection before death, using HIV-specific enzyme linked immunosorbent assay (ELISA and immunoblotting. Autopsy specimens of various organs were examined histologically and microbiologically. Findings: The mean survival period from the moment of detection of seropositivity in all the patients was less than five years. Twelve patients had a parenteral mode of contact, six had been infected by sexual contact, and 14 patients had unknown modes of infection. Most patients (69% had chronic hepatitis C. The main causes of death were various infectious diseases. The most common were generalized miliary tuberculosis and progressive secondary tuberculosis of the lungs. Three (9% patients had tuberculosis of the meninges and five (16% had peritoneal infections, but tuberculous peritonitis had not been diagnosed before death. Six patients had pulmonary tuberculosis and bacterial pneumonia simultaneously. Two (6% patients died from bacterial sepsis as a result of cervical lymphadenitis, and eight (12.5% from abscess-forming pneumonia. The opportunistic infections revealed were Pneumocystis carinii pneumonia (eight patients, cytomegaloviral pneumonia (three, bronchopulmonary aspergillosis (one and mucosal candidiasis (three.

    AIM: To analyze the experience within our hospital and to review the literature so as to establish the best means of diagnosis of abdominal tuberculosis.METHODS: The records of 11 patients (4 males, 7 females,mean age 39 years, range 18-65 years) diagnosed with abdominal tuberculosis in Harran University Hospital between January 1996 and October 2003 were analyzed retrospectively and the literature was reviewed.RESULTS: Ascites was present in all cases. Other common findings were weight loss (81%), weakness (81%), abdominal mass (72%), abdominal pain (72%), abdominal distension (63%), anorexia (45%) and night sweat (36%). The average hemoglobin was 8.2 g/dL and the average ESR was 50 mm/h (range 30-125). Elevated levels of cancer antigen CA-125were determined in four patients. Abdominal ultrasound showed abnormalities in all cases: ascites in all, tuboovarian mass in five, omental thickening in 3, and enlarged lymph nodes (mesenteric, para-aortic) in 2. CT scans showed ascites in all, pelvic mass in 5, retroperitoneal lymphadenopathy in 4, mesenteric stranding in 4, omental stranding in 3,bowel wall thickening in 2 and mesenteric lymphadenopathy in 2. Only one patient had a chest radiograph suggestive of a new TB lesion. Two had a positive family history of pulmonary TB. None had acid-fast bacilli (AFB) in the sputum and the tuberculin test was positive in only two. Laparotomy was performed in 6 cases, laparoscopy in 4 and ultrasoundguided fine needle aspiration in 2. In those patients subjected to operation, the findings were multiple diffuse involvement of the visceral and parietal peritoneum, white 'miliary nodules' or plaques, enlarged lymph nodes, ascites,'violin string' fibrinous strands, and omental thickening.Biopsy specimens showed granulomas, while ascitic fluid showed numerous lymphocytes. Both were negative for acid-fast bacilli by staining. PCR of ascitic fluid was positive for Mycobacterium tuberculosis ( M. tuberculosis) in all cases

    Aims: The aim of this study was to detect Mycobacterium tuberculosis (MTB) DNA with polymerase chain reaction (PCR) in aqueous or vitreous samples of patients suffering from choroiditis presumed to be infectious origin. Settings and Design: Hospital-based, retrospective case–control study. Subjects and Methods: In all, forty eyes of forty patients with choroiditis divided into two groups – Group A (serpiginous-like choroiditis, ampiginous choroiditis, multifocal choroiditis) and Group B (choroidal abscess, miliary tuberculosis (TB), choroidal tubercle) were analyzed retrospectively. In 27 controls (patients without uveitis undergoing phacoemulsification), anterior chamber aspirate was done and sample subjected to real-time PCR. Patients underwent nested PCR for MTB using IS6110 and MPB64 primers from aqueous (n = 39) or vitreous (n = 1). All patients underwent detailed ophthalmological examination by slit-lamp biomicroscopy, fundus examination by indirect ophthalmoscopy, and fundus photograph and fundus fluorescein angiography if required. Statistical Analysis: Positive results of PCR for MTB within the group and between two groups were statistically analyzed using Chi-square test. Results: There were 25 males and 15 females. Mean age at presentation was 34.66 years (range, 14–62). PCR positivity rates were 41.3% (n = 12/29) and 81.82% (n = 9/11) in Groups A and B, respectively. No controls had PCR-positive result. Comparison of PCR positivity rates showed statistically significant difference between Groups A and B (P = 0.028). Systemic TB was detected in 57.14% (n = 12/21) of all PCR-positive cases (Group A - 33.3%, n = 4/12; Group B - 88.9%, n = 8/9). Systemic antitubercular treatment (ATT) for 9 months and oral steroids were successful in resolution of choroiditis in all PCR-positive patients (n = 21) without disease recurrence. Conclusions: Eyes with choroiditis of suspected/presumed tubercular origin should be subjected to PCR for diagnosis of TB and

    Full Text Available É descrito um caso de adiaspiromicose humana, da forma pulmonar disseminada, no qual se empregou o cetoconazol. O paciente, oriundo de Goianésia, GO, referia tosse produtiva, dispnéia e emagrecimento. Doente há dois meses, já fizera uso do esquema tríplice tuberculostático, devido a um radiograma do tórax ter acusado lesões sugestivas de tuberculose miliar. Esse tratamento não surtiu o efeito esperado, pelo que foi ele submetido a uma biópsia pulmonar a céu aberto. A medida permitiu o reconhecimento da natureza fúngica da doença. Passou-se, então, ao emprego do cetoconazol, quando o processo já completara três meses de evolução. Dois meses depois, foi o paciente novamente visto, para controle do tratamento: todas as manifestações respiratórias haviam cessado e um novo radiograma mostrou regressão completa das alterações pulmonares. Apesar disso, é discutida a eficácia do cetoconazol contra C. parvum var crescens, tendo-se em conta o fato de o microrganismo não se reproduzir no hospedeiro.A case of human disseminated pulmonary adiaspiromycosis is reported. The patient, from Goianesia, GO, was admitted to the Brasilia University Hospital, in November 1992, with wet cough, dyspnea and weight loss3/4manifestations that had appeared two months before. Prior to admission, he had been treated for a suspected miliary tuberculosis, because a chest roentgenogram had shown a diffuse reticulonodular infiltrate in both lungs. This therapy brought no improvement to the patient status. An open chest biopsy was then performed, and the microscopic examination of the lung tissue revealed the fungal nature of the disease. Ketoconazole, 400mg/day, was started and the patient discharged from the hospital. He was seen again two months later: the respiratory manifestations had disappeared and a new chest roentgenogram showed complete resolution of the pulmonary lesions. The usefulness of ketoconazole is, however, questioned, since, as there

    An optical system is developed with the aim to detect and monitor three major algal blooms (including harmful algal blooms "HABs") over ecologically relevant scales around India and to strengthen algal forecasting system. This system is designed to be capable of utilizing remote sensing, in situ, and radiative transfer techniques to provide species-specific data necessary for increasing capabilities of an algal forecasting system. With the ability to measure in-water optical properties by means of remote sensing and in situ observations, the optical system developed infers the desired phytoplankton signal from spectral distributions and utilize these data in a numerical classification technique to generate species-specific maps at given spatial and temporal scales. A simple radiative transfer model is adopted for this system to provide a means to optimally interpolate to regions with sparse in situ observation data and to provide a central component to generate in-water optical properties from remotely sensed data. For a given set of inherent optical properties along with surface and bottom boundary conditions, the optical system potentially provides researchers and managers coverage at different locations and depths for tracking algal blooms in the water column. Three major algal blooms focused here include Noctiluca scintillans/miliaris, Trichodesmium erythraeum, and Cochlodinium polykrikoides, which are recurring events in coastal and oceanic waters around India. Because satellite sensors provide a synoptic view of the ocean, both spatially and temporally, our initial efforts tested this optical system using several MODIS-Aqua images and ancillary data. Validation of the results with coincident in situ data obtained from either surface samples or depth samples demonstrated the robustness and potential utility of this approach, with an accuracy of 80-90% for delineating the presence of all three blooms in a heterogeneous phytoplankton community.

    2000-03-27

    Extrinsic allergic alveolitis often occures as bird fancier's lung or is caused by occupational treatment with antigenic materials. In housing environments antigens of allergic alveolitis are also found, especially mould fungi. lf a source of antigens is absent in the anamnesis and the clinical picture as well as the clinical findings are ambiguous, the diagnosis of extrinsic allergic alveolits is delayed or unobtained. The following example shows that in spite of a detailed allergic anamnesis the source of antigens may remain occult and only an inspection of the dwelling rooms leads to an elucidation. - A sixty-one year old non-smoking women was twice admitted to hospital with a temperature of more than 39 degrees C, intense dyspnea on exertion and a strong dry cough under the persumed diagnosis pneumonia. The laboratory values showed nonspecific signs of inflammation, the blood gas analysis was changed to a heavy hypoxemia (pO subset2 49.2 mmHg) and in the chest x-ray there were seen miliary and partly reticular alterations. The chest computed tomography showed extensive densities in both upper and lower parts of the lungs and the pulmonary function test corresponded with a low-grade to middle-grade restriction (VC subsetin = 67%, TLC = 69%). A high dose of corticosteroids produced an improvement of the radiological findings and of the pulmonary function. Also the specialized diagnostic in a hospital for pulmonary diseases yielded no new knowledge, and an interstitial pneumonia was diagnosed. Only the new formation of an acute pneumonic clinical picture on the day of returning to the patients own habitation suggested a noxious substance in the domestic environment. The inspection of the rooms finally showed the source of antigen to be from a condensation water soaked, moulded tapestry on the embrasure of a small unopenable window in the bedroom just on the head of the bed. The nutritive mediums left in the rooms furnished evidence of the mould-species Penicillium

    Full Text Available OBJECTIVE: To identify prognostic factors predicting a fatal outcome in HIV-negative children with neurotuberculosis based on clinical, epidemiological, and laboratory findings. METHOD: The clinical records of all in-patients diagnosed with neurotuberculosis from 1982 to 2005 were evaluated retrospectively. The following prognostic parameters were examined: gender, age, close contact with a tuberculosis-infected individual, vaccination for bacillus Calmette-Guérin, purified protein derivative (PPD of tuberculin results, concomitant miliary tuberculosis, seizures, CSF results, and hydrocephalus. RESULTS: One hundred forty-one patients diagnosed with neurotuberculosis were included. Seventeen percent of the cases resulted in death. The factors that were correlated with a negative outcome included lack of contact with a tuberculosis-infected individual, negative PPD reaction, coma, and longer hospitalisation time. A multiple logistic regression analysis was performed to identify which of these factors most often resulted in death. CONCLUSION: Coma at diagnosis, lack of tuberculosis contact, and a non-reactive PPD were the most important predictors of fatality in patients with neurotuberculosisOBJETIVO: Identificar elementos prognósticos para a letalidade da neurotuberculose na criança, a partir das manifestações clínicas, dados epidemiológicos e laboratoriais.

    Full Text Available Development and standardization of reliable methods for detection of Mycobacterium tuberculosis in clinical samples is an important goal in laboratories throughout the world. In this work, lung and spleen fragments from a patient who died with the diagnosis of miliary tuberculosis were used to evaluate the influence of the type of fixative as well as the fixation and paraffin inclusion protocols on PCR performance in paraffin embedded specimens. Tissue fragments were fixed for four h to 48 h, using either 10% non-buffered or 10% buffered formalin, and embedded in pure paraffin or paraffin mixed with bee wax. Specimens were submitted to PCR for amplification of the human beta-actin gene and separately for amplification of the insertion sequence IS6110, specific from the M. tuberculosis complex. Amplification of the beta-actin gene was positive in all samples. No amplicons were generated by PCR-IS6110 when lung tissue fragments were fixed using 10% non-buffered formalin and were embedded in paraffin containing bee wax. In conclusion, combined inhibitory factors interfere in the detection of M. tuberculosis in stored material. It is important to control these inhibitory factors in order to implement molecular diagnosis in pathology laboratories.O desenvolvimento e a padronização de métodos confiáveis para a detecção de Mycobacterium tuberculosis em amostras clínicas é um objetivo importante nos laboratórios de todo o mundo. Neste trabalho, fragmentos de pulmão e baço de paciente que morreu com o diagnóstico de tuberculose miliar foram usados para avaliar a influência do tipo de fixador e dos protocolos de fixação e inclusão em parafina na performance da PCR. Fragmentos de tecido foram fixados por quatro h a 48 h, usando formalina não tamponada a 10% ou formalina tamponada a 10% e incluídos em parafina pura ou misturada a cera de abelha.

    in the last 50 years. The studies were grouped according to their design (clinical trials, case-control studies, and meta-analyses and the results were presented separately for each type of study. Other relevant topics such as BCG and HIV/AIDS, use of tuberculin skin test, issues related to vaccine scars and to the development of new vaccines were also reviewed. SUMMARY OF THE FINDINGS: BCG vaccine has been used since 1921. However, the data concerning its use are variable and inconsistent. The protective efficacy of the first dose of BCG vaccine against miliary tuberculosis or tuberculous meningitis is remarkably important. Nevertheless, results regarding pulmonary tuberculosis have been inconsistent, either showing no efficacy or a protective efficacy rate around 80%. There is some evidence that a second dose of BCG vaccine does not increase its protective efficacy. Studies have shown that BCG vaccine protects against leprosy. The development of new vaccines to replace BCG in the future has been investigated. CONCLUSIONS: Despite the hope that a new vaccine against tuberculosis will be available in the future, BCG vaccine, in spite of its deficiencies, is today and will still be for many years to come an important tool in controlling the harmful effects of tuberculosis, especially in countries where this disease has moderate to high levels of incidence.

    -control studies and meta-analyses presented separately. RESULTS: The protective effect of the first dose of the BCG vaccine against tuberculosis in its miliary and meningeal forms is high. However, the results vary in relation to the pulmonary form of the disease, with some indicating zero effect and others levels of nearly 80%. Research is being carried out to develop new vaccines that could substitute the BCG or be used as a booster. CONCLUSIONS: There are evidences that the protective effect of the BCG vaccine does not increase with a second dose. In spite of its limitations and the expectation that a new tuberculosis vaccine will be developed in the future, the BCG vaccine remains an important tool in controlling the harmful effects of tuberculosis, particularly in countries with medium or high incidence levels of the disease.

    continued a little more, because BCG vaccination can protect the development of 7 miliary Tb. and/or meningitis cases during 15 years if BCG is given 70% of the infants in 2000. However, it was strongly recommended to stop re-vaccination of BCG, because it is not so effective, and disturb the diagnosis of Tb. infection by tuberculin testing. 9. Treatment of latent Tb. infection will become more and more important, so that it's indication should be expanded to the adults in the future instead of the present indication up to 29 years of age. It is needed to revise Tuberculosis Control Low to improve control programme in Japan. The author hoped that the members of Japan Tuberculosis Society will promote the improvement and to support the Government to improve the Law.

    Full Text Available OBJECTIVES: To determine the frequency of radiological manifestations of chest tuberculosis among the tuberculosis outpatients at the Santa Casa de Misericórdia de São Paulo Hospital, and to correlate these radiological findings with the sputum bacilloscopy. SAMPLE AND METHODS: A review was made of the medical record cards and chest X-rays of all patients attended between January 1996 and December 1998. Patients with a diagnosis of tuberculosis who presented intrathoracic manifestations of the disease and negative anti-HIV serology were selected. RESULTS: The selection included 153 patients, with an average age of 37.5 years, who were predominantly male (60.8% and white (56.9%. Pulmonary lesions were present in 121 (79.9% and extrapulmonary lesions in 32 (20.1%. Parenchymal-infiltrate lesions appeared in 56 patients (36.6%, cavity lesions in 55 (36.0%, pleural effusion in 28 (18.3%, isolated nodules in 6 (3.9%, mediastinal enlargement in 4 (2.6% and miliary pattern in 4 (2.6%. Cavities were present in 45.5% of the patients with pulmonary lesions, generally in association with the parenchymal-infiltrate lesions. Parenchymal infiltrate was present in 86.8% of the patients with pulmonary lesions. There was significant presence of alcohol-acid resistant bacillus in the sputum of patients with cavities (76.4%, in comparison with those without cavities (50% (p = 0.003. CONCLUSIONS: Parenchymal-infiltrate lesions are the most frequent radiological manifestation of pulmonary tuberculosis, and they are generally associated with cavities. There is a relationship between the presence of acid fast bacilli in sputum and pulmonary cavity lesions.OBJETIVOS: Determinar a freqüência das manifestações radiológicas da tuberculose nos pacientes do Ambulatório de Tuberculose do Departamento de Medicina da Santa Casa de Misericórdia de São Paulo, e correlacionar a manifestação radiológica e a baciloscopia direta do escarro.

    -rifampicina continua sendo a escolha apropriada para o início do tratamento.OBJECTIVE: Mycobacteriosis is frequently diagnosed among HIV-infected patients. In Mozambique, where few patients are under antiretroviral therapy and the prevalence of tuberculosis is high, there is need for better characterization of mycobacteria at the species level, as well as for the identification of patterns of resistance to antituberculous drugs. METHODS: We studied a sample of 503 HIV-infected individuals suspected of having pulmonary tuberculosis. Of those 503, 320 tested positive for mycobacteria through sputum smear microscopy or culture of bronchoalveolar lavage fluid. RESULTS: Acid-fast bacilli were observed in the sputum of 73% of the individuals presenting positive cultures. Of 277 isolates tested, only 3 were nontuberculous mycobacteria: 2 were identified as Mycobacterium avium and one was identified as M. simiae. Strains initially characterized as M. tuberculosis complex through polymerase chain reaction restriction analysis (PRA of the hsp65 gene were later confirmed as such through PRA of the gyrB gene. Among the M. tuberculosis isolates, resistance patterns were as follows: to isoniazid, 14%; to rifampin, 6%; and multidrug resistance, 5%. Previously treated cases showed significantly higher rates of resistance to first-line antituberculous drugs. The most common radiological pattern was interstitial infiltrate (in 67%, followed by mediastinal lymph node enlargement (in 30%, bronchiectasis (in 28%, miliary nodules (in 18% and cavitation (in 12%. Patients infected with nontuberculous mycobacteria presented clinical profiles indistinguishable from those of other patients. The median CD4 lymphocyte count in this group was 134 cells/mm³. CONCLUSIONS: There is a strong association between tuberculosis and AIDS in Mozambique, as expected in a country with a high prevalence of tuberculosis. Although drug resistance rates are high, the isoniazid-rifampin regimen continues to be the appropriate

    2000-07-01

    I have engaged in the research on tuberculosis for 50 years, and lessons I have learnt during this period could be summarized in the following ten topics. First is great research achievements by our predecessors on the establishment of so-called primary infection theory on the pathogenesis of TB, planning of TB control principles based on the theory and development of new technologies used for TB control, such as mass miniature X-ray examination and BCG vaccination in 1920s and 1930s. TB control law was enforced in 1951, and the modern TB programme was initiated. Second, the field is a treasure house of interesting data. Several interesting data on TB soon after the World War II in Tokyo and a rural area were collected and analyzed from the mass health examination. Third, looking at the increase of tuberculin positivity with age, it was found that the tuberculin negativity decreased as the exponential function of age, and the current concept of the annual risk of TB infection was already developed in late 1940s. It was 18.1% in male and 11.6% in female in Tokyo in late 1940s. Based on this concept, age specific TB mortality was analyzed by the type of TB, and the rates of miliary TB and TB meningitis were similar to the rate of newly infected to the total population, while the rate of all forms could be divided into early and late death as shown in Fig. 1. Fourth, I suffered from TB by myself from 1951 to 1953, receiving first thoracoplasty in two stages under local anaesthesia, then right upper lobectomy and segmentectomy of superior segment of right lower lobe. From this experience, I learnt a lot about the psychology and suffering of TB patients. Fifth, the importance of recognition of real magnitude of the problem in such a disease as TB in which many TB cases did not aware of their disease. The answer to this was the first TB prevalence survey in 1953 using stratified random sampling method, and based on the results of the survey, the mass health examination

    Objective To observe the immuno-protection in mice attacked with cercaria for a new vaccine candidate of Schistosoma japonicum, the recombinant protein triosephosphate transferase (SjTPM). Methods The BALB/c mice were immunized with the recombinant SjTPM in the dose of 50μg/100μl、 100μg/100μl and 200μg/100μl, the saline solution was used for control group, then attacked with cercaria. The percentage of worm reduction and egg reduction was calculated to evaluate the immuno-protection effect. HE staining method was used to detect the hepatic changes and granulomatous changes in the liver tissue. Results The percentage of worm reduction was 27.1%,32.1% and 35.2%, respectively, in the experimental groups. The number of eggs in liver tissue was reduced by 34.2% ,39.29% ,43.66%, respectively. There were remarkable difference among the experimental groups and control group by t-test. There was no remarkable difference between the experimental groups by X2-test. Gross observation showed that the livers in control groups were dark brown and hard, with miliary nodules or worm eggs diffused in the livers. The recombinant SjTPM group has some extent of amelioration, the livers were bright red, relative soft and smooth, with less nodules of worm eggs in livers. Hepatic histological section demonstrated that there're generous large granulo- degeneration and necrosis of hepatic cells. The recombinant SjTPM vaccine group reversed the hepatic injury better than the control group. The structure of hepatic lobule was integrated on the whole, and the inflammatory reaction around the worm egg granulomas was light. Conclusion The molecular vaccine of rSjTPM had some immuno-protection effect.It suggested that rSjTPM was a potential candidate of S.japonicum.%目的 观察重组日本血吸虫磷酸丙糖转移酶(rSj-TPM)在小鼠抗血吸虫感染中的免疫保护作用,寻找新的血吸虫疫苗候选分子.方法 以rSj-TPM每鼠50μg/100μl、100μg/100μl和200μg/100μl

Methods Twenty - eight patients of elderly tuberculous meningitis from the high - altitude area on the Qinghai - Tibet Plateau who were treated in our hospital between January 2006 and December 2010 were included in the study group, and 30 adolescent and young patients with tuberculous meningitis who were treated in our hospital during the same period were randomly selected as the control group. The disease onset, major clinical symptoms and signs, laboratory results ( cerebrospinal fluid routine examination, biochemical test, purified protein derivative intradermal test, Brain CT and/or MRI examination ), treatment, and prognosis were compared between the two groups. Results The number of cases of subacute or chronic disease onset was 22 and 20 in the study group and the control group, respectively. The study group had lower incidence of fever than the control group ( P 0. 05 ). The proportion of cases with CSF pressure > 200 mm H2O ( 1 mm H2O =0. 0098 kPa ) was lower in the study group than in the control group ( P 0. 05 ). The study group included 12 cases of intracephalic malacia, 8 cases of cerebral infarction, 5 cases of ischemic change, 3 cases of brain tuberculoma, among which 18 cases were combined with severe/moderate hydrocephalus. The control group included 14 cases of intracranial hematogenous miliary tubercle, 10 cases of multiple intracephalic ring enhanced lesions, 6 cases of brain tuberculoma, among which 4 cases were combined with severe/moderate hydrocephalus. The incidence rate of hydrocephalus, malnutrition, diabetes, and drug hepatitis was higher in the study group than in the control group ( P < 0. 05 ). The 4HRZE ( S ) IV6HRZ/12HR was routinely used as the main therapy, and glucoeorticoid, dehydration, and liver protection were used as adjuvant therapies. High intracra-nial pressure and hydroeephalus were given caution and treated in a timely manner. In the study group, 11 cases improved and 17 cases

    膜和肺组织确诊率低.%Objective To study clinical characteristics and diagnostic methods of lymphoma with chest invovement. Methods Twenty-five lymphoma patients with chest involvement were retrospectively analysed, they were all diagnosed in Peking University Third Hospital during 2000 to 2007. The data were collected including clinical manifestations, blood examinations, chest X-ray and CT scan, diagnostic methods and pathologic diagnosis. Results The median age of the 25 patients was 46 years old. Pyrexia(13 cases), weight loss over 10 percent in 6 months(11 cases), cough(10 cases), shortness of breath(9 cases) and painless enlargement of the peripheral lymph nodes(16 cases) were common manifestations. Erythrocyte sedimentation rate and serum lactate dehydrogenase(LDH) level were increased in 72.7% and 81% patients, respectively. The enlargement of mediastinum lymph nodes(16 cases, 64%) was the most common presentation of chest radiography, followed by pulmonary involvement(15 cases, 60%) including infiltration or pulmonary consolidation, mass, multiple nodules, diffuse ground-glass shadow, miliary lesion. There were also presentations of pleural effusion(10 cases, 40%), pericardial effusion(4 cases, 16%), chest wall mass(2 cases, 8%). Eighteen patients(72%) had at least two kinds of these presentations. The appearance of pleural effusion were yellow turbid, bloody or chyliform. Rivaha tests were all positive. The median value of plearal effusion examinations were listed as follows: specific gravity 1.031, total cells 9800×10~6/L, WBC 6.72×10~9/L, lymphocyte 86%, neutrophil 14%, protein 31.4 g/L, LDH 296 U/L,adenosine deaminase (ADA) 67.4 U/L Most patients(16 cases) were diagnosed by surgical biopsy,especialy peripheral lymph nodes biopsy (12 cases). Other patients were diagnosed by ultrasound or CT-guided biopsy (5 cases), video-assisted thoracoscopic pleural biopsy (1 case), video-mediastinoscopic mediastinum lesion biopsy(1 case), bronchial mucosa biopsy through bronchoscope(1 case
