    Vertebral osteomyelitis is one of the most common manifestations of tuberculosis. Magnetic resonance imaging is considered the main imaging modality for the diagnosis, the demonstration of the extent of the disease, and follow-up studies. Vertebral destruction involving two consecutive levels with sparing of the intervertebral disc, disc herniation into the vertebral body, epidural involvement, and paraspinal abscess are the most common MRI findings suggestive of tuberculous vertebral osteomyelitis.

    Vertebral osteomyelitis is most commonly due to pyogenic or granulomatous infection and typically results in the combined involvement of the intervertebral disc and adjacent vertebral bodies. Non-infective causes include the related conditions of chronic recurrent multifocal osteomyelitis (CRMO) and SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome. Occasionally, these conditions may present purely within the vertebral body, resulting in various combinations of vertebral marrow oedema and sclerosis, destructive lesions of the vertebral body and pathological vertebral collapse, thus mimicking neoplastic disease. This review illustrates the imaging features of vertebral osteomyelitis without disc involvement, with emphasis on magnetic resonance imaging (MRI) findings.

    Clinicoroentgenological changes were studied over time in 72 children and adolescents with localized hematogenous osteomyelitis of the lumbar spine. The duration of clinicoroengenological observation ranged from 1 year to 15 years. The dynamic roentgenological followup of a course of hematogenous osteomyelitis developing in the period of growth, made it possible to reveal and describe for the first time an increase in the height of the vertebral bodies which hitherto was regarded in literature as a pathognomonic sign of tuberculous spondylitis. Unlike tuberculosis, in hematogenous osteomyelitis there was an increase in the height not only of the adjacent unaffected but also of the affected vertebrae in case of their superficial or localized focal involvement

    Full Text Available Tuberculous lesions affecting periodontium are rare and seen as secondary infections localized to the soft tissues. With the advent of effective drug therapy, tuberculous lesions of the oral cavity have become rare. Involvement of the periodontium has seldomly been reported in the recent literature. We report a case of tuberculous osteomyelitis of mandible affecting periodontium leading to gingival recession and bone exposure in the mandibular premolar region in a 42-year-old female patient. The diagnosis was based on patient's medical and dental history, bacterial culture, clinical and radiographic examination, blood investigation, immunologic tests, histopathologic examination of the tissue specimen. Patient was already taking antitubercular chemotherapy prescribed by physician. Sequestrectomy and decortications were carried out to remove the affected bone. Healing was uneventful and there was no recurrence after 1½ year of follow-up. Antitubercular chemotherapy along with sequestrectomy and decortication are the treatment of choice for tuberculous osteomyelitic lesions affecting periodontium.

    Nocardia species exist in the environment as a saprophyte; it is found worldwide in soil and decaying plant matter. They often infect patients with underlying immune compromise, pulmonary disease or history of trauma or surgery. The diagnosis of nocardiosis can be easily missed as it mimics many other granulomatous and neoplastic disease. We report a 69-year-old man who presented with chronic back pain and paraparesis. He was found to have Nocardial brasiliensis vertebral osteomyelitis and epidural abscess. Laminectomy and epidural wash out was performed but with no neurological recovery. This is the second reported case of N brasiliensis vertebral osteomyelitis in the literature.

    Two cases of primary multifocal tuberculous osteomyelitis with involvement of the rib cage are presented. The lungs were normal and the appearance of the skeletal lesions did not suggest tuberculosis. These lesions were predominantly lytic, with minimal soft tissue involvement. Tuberculosis should be high in the differential diagnosis of multiple destructive bone lesions, especially in patients from regions where tuberculosis is endemic. (orig.) With 5 figs., 21 refs.

    2015-03-01

    Serratia marcescens is a common nosocomial infection but a rare cause of osteomyelitis and more so of vertebral osteomyelitis. Vertebral osteomyelitis caused by this organism has been reported in few studies. We report a case of S. marcescens vertebral discitis and osteomyelitis affecting multiple non-contiguous vertebras. Although Staphylococcus aureus is the most common cause of vertebral osteomyelitis, rare causes, such as S. marcescens, need to be considered, especially when risk factors such as intravenous heroin use, post-spinal surgery and immunosuppression are present. Therefore, blood culture and where necessary biopsy of the infected region should be undertaken to establish the causative organism and determine appropriate antibiotic susceptibility. Prompt diagnosis of S. marcescens vertebral osteomyelitis followed by the appropriate treatment can achieve successful outcomes.

    We present a rare case of thoracic vertebral osteomyelitis secondary to pulmonary Blastomyces dermatitides. A 27-year-old male presented with three months of chest pains and non-productive cough. Examination revealed diminished breath sounds on the right. CT/MR imaging confirmed a right-sided pre-/paravertebral soft tissue mass and destructive lytic lesions from T2 to T6. CT-guided needle biopsy confirmed granulomatous pulmonary Blastomycosis. Conservative management with antifungal therapy was initiated. Neurosurgical review confirmed no clinical or profound radiographic instability, and the patient was stabilized with TLSO bracing. Serial imaging 3 months later revealed near-resolution of the thoracic soft tissue mass, with vertebral re-ossification from T2 to T6. Fungal osteomyelitis presents a rare entity in the spectrum of spinal infections. In such cases, lytic spinal lesions are classically seen in association with a large paraspinous mass. Fungal infections of the spinal column may be treated conservatively, with surgical intervention reserved for progressive cases manifesting with neurological compromise and/or spinal column instability. Here, we found unexpected evidence for vertebral re-ossification across the affected thoracic levels (T2-6) in response to IV antibiotic therapy and conservative bracing, nearly 3 months later.

    The clinical signs, laboratory data, results of nuclear scintigraphy and radiographic examination of five horses with vertebral body osteomyelitis are described together with response to treatment. Three horses were less than five months of age. Four horses demonstrated hindlimb paresis and in three a focus of pain in the thoracolumbar region could be identified. An umbilical abscess, a caudal lobe lung abscess and a patent urachus were considered primary niduses of infection in each of three horses. Leucocytosis, neutrophilia, anaemia and elevated fibrinogen were the most consistent laboratory abnormalities. Nuclear scintigraphy was performed in three horses and identified the site of the vertebral lesion which was subsequently evaluated radiographically. In the other two horses radiographic examination in the region of areas of focal pain identified a lesion. Radiographic abnormalities included compression fractures of vertebral bodies (two), proliferative new bone (three) and soft tissue swelling ventral to a vertebral body (one). Two horses, including one with a compression fracture of the second lumbar vertebra, received parenteral antimicrobial therapy for 40 and 74 days, respectively. When re-examined six months later they showed no neurological abnormalities. The other three horses failed to respond to antimicrobial treatment and were humanely destroyed. The horse with a lung abscess also had an abscess cranial to the right tuber coxae which extended into the vertebral bodies of the third and fourth lumbar vertebrae from which Streptococcus zooepidemicus was cultured. A horse with proliferative new bone on the ventral aspect of the fifth and sixth thoracic vertebrae had a mediastinal mass associated with these vertebrae and fungal granulomas, from which Aspergillus species was cultured, in the heart and aorta, trachea, spleen and kidney. The horse with a patent urachus and soft tissue swelling ventral to the vertebral body of the 12th thoracic vertebra

    Full Text Available La osteomielitis vertebral piógena (OVP es una localización poco frecuente (2-7% Se confirma con el aislamiento de un microorganismo de una vértebra, disco intervertebral, absceso epidural o paravertebral. Se describe una serie de casos por la infrecuente presentación de esta enfermedad, que puede ser consulta inicial en los servicios de clínica médica y por su sintomatología inespecífica que supone una dificultad diagnóstica. Tanto la columna lumbar como la dorsal fueron los sitios más afectados. El dolor dorsolumbar y la paraparesia fueron los síntomas más frecuentes de presentación. En ocho pacientes se aislaron Staphylococcus aureus, en uno Escherichia coli y en el restante Haemophylus sp. Se observó leucocitosis sólo en tres pacientes, y en dos velocidad de sedimentación globular mayor de 100 mm/h. Los diez pacientes presentaron imágenes características de osteomielitis vertebral piógena en la resonancia nuclear magnética. Dentro de las complicaciones, los abscesos paravertebrales y epidurales fueron los más frecuentes (en cinco enfermos. Además, un paciente presentó empiema pleural. De los diez pacientes de esta serie, siete recibieron inicialmente tratamiento médico empírico y luego específico para el germen aislado. En los restantes el tratamiento fue guiado de acuerdo al antibiograma. A dos enfermos fue necesario realizarles laminectomía descompresiva por compromiso de partes blandas y a otros dos estabilización quirúrgica por inestabilidad espinal, observándose buena evolución en todos los casos. Esta serie demuestra que, ante un paciente con dolor dorsolumbar y síntomas neurológicos se deberá tener en cuenta esta entidad para evitar un retraso en el tratamiento.Pyogenic osteomyelitis seldom affects the spine (2-7%.

    Aim: To describe the magnetic resonance imaging (MRI) appearances in patients with a clinical history suggestive of vertebral osteomyelitis and discitis who underwent MRI very early in their clinical course. Materials and methods: A retrospective review of the database of spinal infections from a spinal microbiological liaison team was performed over a 2 year period to identify cases with clinical features suggestive of spinal infection and an MRI that did not show features typical of vertebral osteomyelitis and discitis. All patients had positive microbiology and a follow up MRI showing typical features of spinal infection. Results: In four cases the features typical of spinal infection were not evident at the initial MRI. In three cases there was very subtle endplate oedema associated with disc degeneration, which was interpreted as Modic type I degenerative endplate change. Intravenous antibiotic therapy was continued prior to repeat MRI examinations. The mean time to the repeat examination was 17 days with a range of 8-22 days. The second examinations clearly demonstrated vertebral osteomyelitis and discitis. Conclusion: Although MRI is the imaging method of choice for vertebral osteomyelitis and discitis in the early stages, it may show subtle, non-specific endplate subchondral changes; a repeat examination may be required to show the typical features.

    PURPOSE To describe pyogenic vertebral osteomyelitis as a rare infection associated with endogenous endophthalmitis.METHODS A retrospective review of three patients with endogenous endophthalmitis and sepsis due to underlying Staphylococcal vertebral osteomyelitis presenting during a 21-month time period. The ophthalmic and systemic features and management and outcomes are presented.RESULTS One patient developed unilateral endophthalmitis with cervical spine osteomyelitis, Staphylococcus aureus being isolated from blood cultures. The second presented with bilateral endophthalmitis with disseminated Methicillin-resistant S. aureus (MRSA) infection, with thoracic and lumbar discitis and para-spinal abscesses. MRSA was cultured from vitreous, blood, and synovial fluid. Both patients received prolonged courses of intravenous antibiotics. Intravitreal antibiotic therapy was used in the second patient. Excellent visual and systemic outcomes were achieved in both cases with no ocular complications. The third patient developed lumbar osteomyelitis following spinal surgery and presented with disseminated S. aureus sepsis including unilateral endogenous endophthalmitis. Despite systemic antibiotics and intensive care the patient died.CONCLUSIONS Endogenous endophthalmitis should be suspected in septic patients developing eye symptoms. Endogenous endophthalmitis with staphylococcal bone infection is a rare but serious condition. Osteomyelitis should be considered as an infective source in any such patient reporting bone pain or reduced spinal mobility. Prompt investigation and treatment can achieve favourable visual and systemic outcomes.

    A young Somali immigrant presents with a two-year history of a large, firm, painful right anterolateral chest wall sternal mass. The patient denied any history of trauma or infection at the site and did not have a fever, erythematous lesion at the site, clubbing, or lymphadenopathy. A lateral chest radiograph demonstrated a low density mass isolated to the subcutaneous soft tissue overlying the sternum, ribs and clavicle. Computed tomography (CT) with contrast demonstrated a cystic lesion in the right anterolateral chest wall deep to the pectoralis muscle. Enhanced CT of the chest demonstrated sclerosis and destruction of the rib and costochondral joint and manubrio-sternal joint narrowing. Ultrasound-guided biopsy and aspiration returned 500 cc of purulent, cloudy yellow, foul-smelling fluid. Acid-fact bacilli stain and the nucleic acid amplification test identified and confirmed Mycobacterium tuberculosis. A diagnosis of tuberculous osteomyelitis/septic arthritis was made and antibiotic coverage for tuberculosis was initiated.

    2014-01-01

    Full Text Available Mycobacterium abscessus infections rarely develop in healthy individuals, and mostly they occur in immunocompromised hosts. Vertebral osteomyelitis due to Mycobacterium abscessus is very rare and only three previous cases of spinal infection caused by Mycobacterium abscessus have been reported. Mycobacterium abscessus isolates are uniformly resistant to antituberculous agents and can display a virulent biofilm-forming phenotype. The patient was a 67-year-old woman with vertebral osteomyelitis of the L1-2. She was healthy without immune-suppressed condition, history of trauma, or intravenous drug use. The smear examination of the specimen harvested by CT-guided puncture of the paravertebral abscess revealed Mycobacterium abscessus. Her disease condition did not abate with conservative treatment using antimicrobial chemotherapy. Radical debridement of the vertebral osteomyelitis and anterior reconstruction from T12 to L2 using antibacterial iodine-supported instrumentation were performed. Chemotherapy using clarithromycin, amikacin, and imipenem was applied for 6 months after surgery as these antibiotics had been proven to be effective to Mycobacterium abscessus after surgery. Two years after surgery, the infected anterior site healed and bony fusion was successfully achieved without a recurrence of infection.

    The aim of this study was to determine the diagnostic value of 18 F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) and magnetic resonance imaging (MRI) in diagnosing vertebral osteomyelitis. From November 2015 until December 2016, 32 patients with suspected vertebral osteomyelitis were prospectively included. All patients underwent both 18 F-FDG-PET/CT and MRI within 48 h. All images were independently reevaluated by two radiologists and two nuclear medicine physicians who were blinded to each others' image interpretation. 18 F-FDG-PET/CT and MRI were compared to the clinical diagnosis according to international guidelines. For 18 F-FDG-PET/CT, sensitivity, specificity, PPV, and NPV in diagnosing vertebral osteomyelitis were 100%, 83.3%, 90.9%, and 100%, respectively. For MRI, sensitivity, specificity, PPV, and NPV were 100%, 91.7%, 95.2%, and 100%, respectively. MRI detected more epidural/spinal abscesses. An important advantage of 18 F-FDG-PET/CT is the detection of metastatic infection (16 patients, 50.0%). 18 F-FDG-PET/CT and MRI are both necessary techniques in diagnosing vertebral osteomyelitis. An important advantage of 18 F-FDG-PET/CT is the visualization of metastatic infection, especially in patients with bacteremia. MRI is more sensitive in detection of small epidural abscesses.

    1988-01-01

    Clinico-roentgenological changes in dynamics are studied in 72 children and adolescents with a limited hematogenous vertebrae body osteomyelitis. The clinico-roentgenologic examination lasted from 1 to 15 years. Such a durable examination permitted to trace the development, regularities and remote results of the disease. The increase in vertebrae body height (lengthening) which is considered a pathognomonic sign of tuberculous spondylitis is described for the first time. Unlike tuberculosis, hematogenous spondylitis brings about the body lengthening of both ajacent nonaffected and affected vertebrae in the case of their surface or limited focal injury. 12 refs.; 1 fig

    The purpose of this study was to prospectively evaluate USPIO-enhanced MR imaging for the differentiation of vertebral infectious osteomyelitis and sterile inflammation. Vertebral osteomyelitis and sterile vertebral inflammation were induced in two groups of six rabbits each. MRI examinations were performed including unenhanced and gadolinium-enhanced fat-saturated SE T1w sequences. Once endplate enhancement was observed on the T1 gadolinium-enhanced MR sequence, a second MRI examination (SE T1w sequence) was performed 24 h after USPIO administration (45 {mu}mol Fe/kg). MR imaging was correlated with histopathological findings (macrophage immunostaining and Perls Prussian blue staining). On gadolinium-enhanced T1 sequences, a significant SNR increase in vertebral endplates was present in both groups without significant difference between the two groups (P = 0.26). On USPIO-enhanced T1 sequences, a significant SNR increase was only observed in the infection group (P = 0.03) with a significant difference in SNR between the infection and the sterile-inflammation groups (P = 0.002). Infected areas presented replacement of bone marrow by an intense macrophage infiltration, some being iron-loaded. Sterile inflammation showed a replacement of bone marrow by inflammatory tissue with only rare macrophages without any Perls blue staining. USPIO-enhanced MR imaging can distinguish infectious osteomyelitis from sterile vertebral inflammation due to different macrophage distributions in the two lesions. (orig.)

    After a brief introduction outlining some basic principles regarding the diagnosis of osteomyelitis, pathophysiologic aspects are reviewed. Advantages and disadvantages of each imaging modality and their applications in different forms of osteomyelitis are discussed. The use of different imaging modalities in the diagnosis of special forms of osteomyelitis, including chronic, diabetic foot, and vertebral osteomyelitis, and osteomyelitis associated with orthopedic appliances and sickle cell disease is reviewed. Taking into account the site of suspected osteomyelitis and the presence or absence of underlying pathologic changes and their nature, an algorithm summarizing the use of various imaging modalities in the diagnosis of osteomyelitis is presented.

    Streptavidin accumulates at sites of inflammation and infection as a result of increased capillary permeability. In addition to being utilised by bacteria for their own growth, biotin forms a stable, high-affinity non-covalent complex with avidin. The objective of this investigation was to determine the diagnostic performance of two-step streptavidin/ 111 In-biotin imaging for evaluating patients with suspected vertebral osteomyelitis. We evaluated 55 consecutive patients with suspected vertebral osteomyelitis (34 women and 21 men aged 27-86 years), within 2 weeks after the onset of clinical symptoms. Thirty-two of the patients underwent magnetic resonance imaging (MRI) and 24, computed tomography (CT). DTPA-conjugated biotin was radiolabelled by incubating 500 μg of DTPA-biotin with 111 MBq of 111 In-chloride. Two-step scintigraphy was performed by first infusing 3 mg streptavidin intravenously, followed 4 h later by 111 In-biotin. Imaging was begun 60 min later. Streptavidin/ 111 In-biotin scintigraphy was positive in 32/34 patients with spinal infection (94.12% sensitivity). The study was negative in 19/21 patients without infection (95.24% specificity). The corresponding results for MRI and CT were 54.17% and 35.29% (sensitivity), and 75% and 57.14% (specificity), respectively. All statistical parameters of diagnostic performance (Youden's J index, kappa measure of agreement with correct classification, accuracy, sensitivity, specificity, positive likelihood and negative likelihood) were clearly better for streptavidin/ 111 In-biotin scintigraphy than for either MRI or CT. Streptavidin/ 111 In-biotin scintigraphy is highly sensitive and specific for detecting vertebral osteomyelitis in the first 2 weeks after the onset of clinical symptoms, and is potentially very useful for guiding clinical decisions on instituting appropriate therapy.

    Background: Biopsy with demonstration of the infectious organism is the gold standard for diagnosing spondylodiscitis. The purpose of this study is to evaluate the positive culture rate of image-guided percutaneous biopsy in cases of radiologically suspected and unsuspected spinal osteomyelitis and to assess the role of pathology in diagnosis. Methods: With IRB approval and in compliance with HIPAA regulations, the charts of patients undergoing 323 consecutive image-guided percutaneous spinal biopsies performed by one musculoskeletal radiology department between January 2001 and March 2007 were reviewed. Image guidance was via fluoroscopy or computed tomography. Radiological and clinical suspicion, cultures, and pathology were assessed and compared to previously published reports. Results: In 92 cases radiographically and clinically consistent with infection (high probability of infection), 28 specimens yielded positive cultures (30.4%). Positive cultures resulted from 5 of 31 cases (16.1%) radiographically indeterminate for infection (intermediate probability of infection versus tumor). When radiographically not suggestive of infection (low probability of infection, i.e. suspicious for tumor), 10 of 200 cultures were positive (5.0%). From 113 cases sent to pathology with an intermediate or high suspicion for infection, 63 were histopathologically diagnosed as such (55.8%). Cultures were positive in 19 of those 63 cases (30.2%). Culture and/or pathology was positive in 73 (64.6%) of the 113 cases. There were no significant differences in rates of positive culture or pathology by vertebral region (p = 0.51, p = 0.81). The most frequently identified organisms were Staphylococcus aureus (13) and coagulase negative staphylococci (13). Conclusions: Our results suggest that the positive culture rate of percutaneous spinal biopsy specimens is 30.4% with radiographically high probability for infection, which is lower than previously published. Infection may also be present

    Duration of treatment for patients with vertebral osteomyelitis is mainly based on expert recommendation rather than evidence. We aimed to establish whether 6 weeks of antibiotic treatment is non-inferior to 12 weeks in patients with pyogenic vertebral osteomyelitis. In this open-label, non-inferiority, randomised controlled trial, we enrolled patients aged 18 years or older with microbiologically confirmed pyogenic vertebral osteomyelitis and typical radiological features from 71 medical care centres across France. Patients were randomly assigned to either 6 weeks or 12 weeks of antibiotic treatment (physician's choice in accordance with French guidelines) by a computer-generated randomisation list of permuted blocks, stratified by centre. The primary endpoint was the proportion of patients who were classified as cured at 1 year by a masked independent validation committee, analysed by intention to treat. Non-inferiority would be declared if the proportion of cured patients assigned to 6 weeks of treatment was not less than the proportion of cured patients assigned to 12 weeks of treatment, within statistical variability, by an absolute margin of 10%. This trial is registered with EudraCT, number 2006-000951-18, and Clinical Trials.gov, number NCT00764114. Between Nov 15, 2006, and March 15, 2011, 359 patients were randomly assigned, of whom six in the 6-week group and two in the 12-week group were excluded after randomisation. 176 patients assigned to the 6-week treatment regimen and 175 to the 12-week treatment regimen were analysed by intention to treat. 160 (90·9%) of 176 patients in the 6-week group and 159 (90·9%) of 175 of those in the 12-week group met the criteria for clinical cure. The difference between the groups (0·05%, 95% CI -6·2 to 6·3) showed the non-inferiority of the 6-week regimen when compared with the 12-week regimen. 50 patients in the 6-week group and 51 in the 12-week group had adverse events, the most common being death (14 [8%] in

    A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

    Salmonella infection can cause four predominant clinical syndromes: enteric fever, acute gastroenteritis, bacteraemia with or without metastatic infection, and the asymptomatic carrier state. Salmonella as an aetiological agent in osteomyelitis is essentially rare and salmonella osteomyelitis in itself is predominantly seen in patients with haemoglobinopathies such as sickle cell disease or thalassemia. There are very few cases reported in the literature in which salmonella osteomyelitis is s...

    Radiographic observation of 152 cases of tuberculous spondylitis selected from total 194 cases of tuberculous arthritis during the past 6 years and 8 months, was carried out to study. 1. The youngest one was 15 months old male infant of active tuberculous spondylitis. The active tuberculous spondylitis under 10 years of age were 50 percent (28 cases). 2. The ratio of male to female was 1.5:1 3. The most common site of involvement was the lumbar spine which was 44.1 percent of the total tuberculous spondylitis. The next were thoracic spine (33.6%), and thoraco-lumber spine (13.1%). 4. The most common roentgenographic findings are bony destructions of the vertebral bodies which were 97.4 percent. The next were joint space narrowing (93.4%), osteoporosis (79.6%), kyphosis (34.2%), fusion deformity of the vertebral body (25.7%), and cold abscess shadow (16.4%). 5. The most of patients (88.8%) had or have been pulmonary tuberculous lesions. 6. In annual incidence, the number of patients were not changed greatly.

    Fungal osteomyelitis is a rare infection that usually develops in immunocompromised patients. Additionally, involvement of the cervical spine by Candida albicans is extremely rare; only three previous cases of Candida vertebral osteomyelitis have been reported in the literature. The diagnosis may be delayed due to nonspecific radiologic findings and a slow progression. We report the CT, MRI, bone scan, and PET-CT findings in a patient who developed Candida osteomyelitis, which was initially misdiagnosed as metastasis, at the atlas and axis following treatment for nasopharyngeal cancer.

    To summarize the incidence and spectrum of spinal cord-related complications in patients of tuberculous meningitis. Reports from multiple countries were included. An extensive review of the literature, published in English, was carried out using Scopus, PubMed and Google Scholar databases. Tuberculous meningitis frequently affects the spinal cord and nerve roots. Initial evidence of spinal cord involvement came from post-mortem examination. Subsequent advancement in neuroimaging like conventional lumbar myelography, computed tomographic myelography and gadolinium-enhanced magnetic resonance-myelography have contributed immensely. Spinal involvement manifests in several forms, like tuberculous radiculomyelitis, spinal tuberculoma, myelitis, syringomyelia, vertebral tuberculosis and very rarely spinal tuberculous abscess. Frequently, tuberculous spinal arachnoiditis develops paradoxically. Infrequently, spinal cord involvement may even be asymptomatic. Spinal cord and spinal nerve involvement is demonstrated by diffuse enhancement of cord parenchyma, nerve roots and meninges on contrast-enhanced magnetic resonance imaging. High cerebrospinal fluid protein content is often a risk factor for arachnoiditis. The most important differential diagnosis of tuberculous arachnoiditis is meningeal carcinomatosis. Anti-tuberculosis therapy is the main stay of treatment for tuberculous meningitis. Higher doses of corticosteroids have been found effective. Surgery should be considered only when pathological confirmation is needed or there is significant spinal cord compression. The outcome in these patients has been unpredictable. Some reports observed excellent recovery and some reported unfavorable outcomes after surgical decompression and debridement. Tuberculous meningitis is frequently associated with disabling spinal cord and radicular complications. Available treatment options are far from satisfactory.

    Tuberculous meningitis is an infection of the the membranes covering the brain and spinal cord (meninges). Tuberculous meningitis is a major global health problem and is the most severe form of extrapulmonary tuberculosis, with high rate mortality. Last years in Kosovo incidence of TB was decreased in less than 1000 cases per year and 10-20 cases per year of TB meningoencephalitis. Still Kosovo has limited numbers of TB. TBM is diagnosed on the basis of clinical features, cerebrospinal fluid (CSF) studies, and radiological findings. Clinical picture, neurological status, anamnestic data, suspect (but not specific) lab tests, and imaging new methods, together can give very valuable help to clinicians for early adequate and successful treatment.

    Osteomyelitis is defined as an inflammation or infection in bone tissues - cancellous bone, bone marrow, bone compacta and periosteum due to invasion of infection from surrounding tissues. Maxillary osteomyelitis is less common disease than osteomyelitis of mandible. This can be explained by anatomical structure of maxilla which is mainly composed of sinuses and thin bone lamellae. Such a structure allows rapid propagation of the infection to the surface. There have been examined and treated 70 patients with osteomyelitis of facial bones within past 15 years at Department of stomatology and maxillo-facial surgery of P.J. Safarik University in Kosice. Only four cases were diagnosed as maxillary osteomyelitis. The aim of this study was to mention the differences in anatomy and symptoms of acute and chronic stage of maxillary osteomyelitis and to give a detailed radiographic picture of this affliction.

    Objective: To find out the different clinical presentations of breast tuberculosis and its treatment outcome. Subjects and Methods: Fifty consecutive female patients above 13 years presenting with breast lump, multiple sinuses, axillary lymphadenopathy, and cold abscess were included in the study. Medical records of the patients presented were reviewed and analyzed. Data was collected regarding the patient's name, age and marital and lactational status. Clinical Examinations and investigations were carried out by triple assessment i.e. clinical, radiological and histological/cytological evaluation. Results: The commonest presentation was a solitary breast lump in 30 (60%) patients, breast lump with axillary lymphadenopathy in 13 (26%). Four (8%) patients presented with generalized breast swelling (edema) with ipsilateral axillary lymphadenopathy. Two (4) presented with breast abscess and axillary lymphadenopathy and one (2%) with axillary sinus and breast lump. Upper outer quadrant was most frequently involved in 29 (58%) of patients. Thirty two (64%) cases were secondary to tuberculosis in other sites, mostly (40%) from tuberculous axillary lymphadenitis. Forty eight (96%) patients responded well to one year antituberculous treatment with complete disappearance of the lumps except 2 patients who had shrinkage of lump size only, underwent excision of lump. Conclusion: Solitary lump and enlarged lymph nodes are the commonest presentation of mammary tuberculosis. Early diagnosis and treatment is necessary to prevent disfigurement of breast. Antituberculous therapy is the treatment of choice. Surgery should be reserved for unresponsive lumps. (author)

    Seventeen MR studies were performed on 16 children with acute, chronic, or healed osteomyelitis. Abnormality was detected in the soft tissues and bone marrow in all patients with acute or chronic osteomyelitis. Two of three patients with heated osteomyelitis had normal soft tissues and bone marrow. There was overlap in the appearance of acute and chronic osteomyelitis. The patients with acute osteomyelitis, however, tended to have more extensive soft-tissue abnormality, to have more poorly defined margins to the soft-tissue abnormality, and more poorly defined interfaces between normal and diseased bone marrow. The signal characteristics of diseases soft tissue and marrow were compatible with prolongation of T1 and T2 relaxation times as compared with normal muscles

    Twenty-eight pressure sores were evaluated prospectively. Osteomyelitis was reported histologically in nine of 28 bones and pressure-related changes were reported in 14 bones. Roentgenograms suggested the presence of osteomyelitis in four instances of histologically proved osteomyelitis. Technetium Tc 99m medronate bone scans were highly sensitive, showing increased uptake in all cases of osteomyelitis; however, increased uptake also occurred commonly in uninfected bones due to pressure-related changes or other noninfectious causes. Cultures of bone biopsy samples usually disclosed anaerobic bacteria, gram-negative bacilli, or both. The diagnosis of osteomyelitis must be considered if a pressure sore does not respond to local therapy. If the technetium Tc 99m medronate uptake is increased in the involved area, or roentgenographic findings are abnormal, the diagnosis can only be made with certainty by histologic examination of bone. Antibacterial treatment should be selected based on the results of bone culture

    Background The epidemiology, pathogenesis, diagnosis, and management of Aspergillus osteomyelitis are not well understood. Methods Protocol-defined cases of Aspergillus osteomyelitis published in the English literature were reviewed for comorbidities, microbiology, mechanisms of infection, clinical manifestations, radiological findings, inflammatory biomarkers, antifungal therapy, and outcome. Results Among 180 evaluable patients, 127 (71%) were males. Possible predisposing medical conditions in 103 (57%) included pharmacological immunosuppression, primary immunodeficiency, and neutropenia. Seventy-three others (41%) had prior open fracture, trauma or surgery. Eighty (44%) followed a hematogenous mechanism, 58 (32%) contiguous infections, and 42 (23%) direct inoculation. Aspergillus osteomyelitis was the first manifestation of aspergillosis in 77%. Pain and tenderness were present in 80%. The most frequently infected sites were vertebrae (46%), cranium (23%), ribs (16%), and long bones (13%). Patients with vertebral Aspergillus osteomyelitis had more previous orthopedic surgery (19% vs 0%; P=0.02), while those with cranial osteomyelitis had more diabetes mellitus (32% vs 8%; P=0.002) and prior head/neck surgery (12% vs 0%; P=0.02). Radiologic findings included osteolysis, soft-tissue extension, and uptake on T2-weighted images. Vertebral body Aspergillus osteomyelitis was complicated by spinal-cord compression in 47% and neurological deficits in 41%. Forty-four patients (24%) received only antifungal therapy, while 121(67%) were managed with surgery and antifungal therapy. Overall mortality was 25%. Median duration of therapy was 90 days (range, 10–772 days). There were fewer relapses in patients managed with surgery plus antifungal therapy in comparison to those managed with antifungal therapy alone (8% vs 30%; P=0.006). Conclusions Aspergillus osteomyelitis is a debilitating infection affecting both immunocompromised and immunocompetent patients. The most

    Technetium- 99 pyrophosphate bone scanning often identifies patients with osteomyelitis before roentgenographic findings appear. However, recent studies have shown that 99 Tc bone scanning often gives false-negative results, especially in neonates. The accuracy of computed tomographic scanning and indium-111 leukocyte scanning for diagnosis of early osteomyelitis has not been established. 99 Tc bone scanning often gives false-positive results in patients with other conditions leading to bone injury and repair, such as trauma or recent surgery, further limiting the usefulness of this imaging procedure. Newer imaging techniques have not been adequately evaluated to establish their specificity. Because of their high cost and unproved accuracy, these new imaging procedures should not be routinely applied until their usefulness has been established. Bone biopsy remains the procedure of choice for establishing the diagnosis in patients suspected clinically to have osteomyelitis with negative findings on roentgenography and 99 Tc bone scanning. Although Staphylococcus aureus is the leading cause of osteomyelitis, other pathogens cause 30 to 40 percent of cases. Aspiration or biopsy of the involved bone is usually required to choose appropriate antibiotic therapy. Bone biopsy is essential in chronic osteomyelitis, since cultures of sinus drainage are unreliable. Osteomyelitis in diabetics with foot infection and in association with decubitus ulcers presents special problems. Radionuclide scanning often give false-positive results in these patients. Proper diagnosis usually requires careful assessment of clinical and roentgenographic findings. 33 references

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI.

    There are aetiological, clinical, radiological and therapeutic differences between musculoskeletal infection in the neonate (and infant) and in older children and adults. Due to the anatomy and blood supply in neonates, osteomyelitis often co-exists with septic arthritis. Discitis is more common in infants whereas vertebral body infection is more common in adults. This review article discusses the important clinical and radiological differences that in the past have led many authors to consider neonatal osteomyelitis a separate entity from osteomyelitis in the older child

    Full Text Available Osteomyelitis of the maxilla is now a rare event with the advent of antibiotics. The two predominant causes are odontogenic infections and sinusitis. Immunocompromised states such as diabetes, HIV, and malnutrition increase the risk of osteomyelitis. It is important to recognize this early as it is a difficult entity to treat with potentially serious consequences. We report an unusual case of right sided maxillary osteomyelitis in a lady with poorly controlled diabetes in rural Lincolnshire. Biopsy of the right maxillary bone showed features of acute osteomyelitis. This responded well to a prolonged course of oral antibiotics.

Thereafter a protein- and lymphocyte-rich ascites developed. CT-scans revealed a thickened visceral peritoneum and multiple, marginally increased retroperitoneal lymph nodes. The history of the patient originating from former Jugoslavia was suspicious for inadequately treated tuberculous pericarditis. Hence this diagnosis tuberculous peritonitis became probable but for practical reasons could not be proven neither by biopsy nor by culture. Under probatory antituberculous treatment the patient's general condition improved rapidly, the ascites disappeared and initially elevated parameters for infection normalized.

    Objective: To investigate CT imaging features of tuberculous spondylitis in children. Methods: The CT imagings of two groups of patients with Tuberculous Spondylitis between January 2004 and March 2008 were retrospectively reviewed. One group included 28 children from 0 to 14 years old. Another group included 159 adults. All the patients were diagnosed as tuberculous spondylitis by pathology or biopsy, or by anti-turboelectric therapy. The CT imagings of the two groups were read retrospectively, including infections of vertebras and its appendix, the proportion of the total length of paravertebral abscess to the height of relative vertebra, the information of paravertebral abscess and dura mate of spinal cord and nerve root compression. Results The ratio of kyphosis in children group was 75% (21/28), higher than that in adults'. Tuberculous spondylitis in children was most often involved thoracic vertebra (53.7%,51/95). In children, involvement was more often seen than that of cervical vertebra and lumbar. The ratio of tuberculous spondylitis of children's cervical vertebrae was 10.5% (10/95)and of lumbar was 31.6% (30/95, while in adults that of cervical vertebrae was 3.3% (16/479)and of lumbar was 44.5% (213/479). There was statistical difference between them. The percentages of central type of tuberculous vertebral osteitis in chlidren was 57.1% (16/28)and was different with that in adults'(P=0.001 0.05). The incidence of dura mate of spinal cord or nerve root compression in children was 78.6%(22/28), much higher than that in adults (49.7%(79/159), P=0.005 <0.05). Conclusion: Special features of tuberculous spondylitis in childrencan be observed on CT imaging, kyphosis is often seen. The incidence of tuberculous spondylitis of thoracic vertebra and cervical vertebrae is high, central type of tuberculous vertebral osteitis in children is more popular than that in adults, but there is higher ratio of dura mate of spinal cord or nerve root compression in children

    Full Text Available ABSTRACT INTRODUCTION: Carcinomatous degeneration is a rare and late complication developing decades after the diagnosis of chronic osteomyelitis. OBJECTIVES: To present the results from a retrospective study of six cases of squamous cell carcinoma arising from chronic osteomyelitis. METHODS: Six cases of chronic osteomyelitis related to cutaneous squamous cell carcinoma were identified. The cause and characteristics of the osteomyelitis were analyzed, as well as time up to malignancy, the suspicion signs for malignancy, the localization and histological type of the cancer, and the type and result of the treatment. RESULTS: The mean time between osteomyelitis onset and the diagnosis of malignant degeneration was 49.17 years (range: 32-65. The carcinoma resulted from tibia osteomyelitis in five cases and from femur osteomyelitis in one. The pathological examination indicated cutaneous squamous cell carcinoma in all cases. All the patients were staged as N0M0, except for one, whose lomboaortic lymph nodes were affected. The treatment consisted of amputation proximal to the tumor in all patients. No patient presented signs of local recurrence and only one had carcinoma metastasis. CONCLUSION: Early diagnosis and proximal amputation are essential for prognosis and final results in carcinomatous degeneration secondary to chronic osteomyelitis.

    To evaluate, if possible, the radiographic features of tuberculous osteitis in the greater trochanter and ischium, and to determine the cause of the lesions. We reterospectively reviewed the plain radiographic findings of 14 ptients with histologically proven tuberculous osteitis involving the greater trochanter and ischium. In each case, the following were analyzed:morphology of bone destruction, including cortical erosion;periosteal reaction;presence or abscence of calcific shadows in adjacent soft tissue. On the basis of an analysis of radiographic features and correlation of the anatomy with adjacent structures we attempted to determine causes. Of the 14 cases evaluated, 12 showed varrious degrees of extrinsic erosion on the outer cortical bone of the greater trochanter and ischium ; in two cases, bone destruction was so severe that the radiographic features of advanced perforated osteomyelitis were simulated. In addition to findings of bone destruction, in these twelve cases, the presence of sequestrum or calcific shadows was seen in adjacent soft tissue. Tuberculous osteitis in the greater trochanter and ischium showed the characteristic findings of chronic extrinsic erosion. On the basis of these findings we can suggest that these lesions result from an extrinsic pathophysiologic cause such as adjacent bursitis

    Full Text Available We present a 49 year old man who presented to the emergency department with severe lower back pain of 5 days duration. One week prior he had been diagnosed with a right psoas muscle abscess and was discharged with a 28 day course of moxifloxacin after the preliminary culture from the psoas grew an anaerobic organism. MRI of the lumbar spine showed marrow edema in the L2 body, occupying most of the anterior two thirds of the body, with cortical erosion at the anteroinferior aspect of L1. Blood cultures were negative and bone biopsy of L2 showed neutrophilic invasion and reactive changes. Cultures grew Prevotella oralis. Hematogenous spread from a composite bonding procedure for exposed teeth roots is thought to be the source for the vertebral osteomyelitis. This is a plausible spread of infection in our case because it was thought that the osteomyelitis occurred first and spread to the psoas muscle.

  15. Osteomyelitis: a current challenge

    Directory of Open Access Journals (Sweden)

    Luciana Souza Jorge

    Full Text Available Over the last 30 years, the pathogenesis of osteomyelitis has almost been totally elucidated, and many factors responsible for the persistence of this infection have been identified. Numerous antimicrobial agents with distinct spectrums of action, pharmacokinetics, and pharmacodynamics have been used in its treatment. Surgical techniques, including muscle grafts, the Ilizarov technique, and antibiotic bone cements, have been applied. However, bone infections are still a challenge. Despite the importance of isolation and identification of microorganisms to determine the antimicrobial treatment of bone infections, there are few systematic national studies about the etiological profile of these diseases. This article describes the current knowledge of osteomyelitis and summarizes published national data based on the experience of different Orthopedic and Traumatology Services. In general, S. aureus was described as an important etiological agent; however, the difference in design of national studies makes a comparison between the prevalence of bone infection, the associated risk factors, and the different therapeutic approaches difficult. In conclusion, effort is necessary in order to stimulate systematic national studies in different Orthopedics and Traumatology Services to obtain a better consensus on preventive measures and therapies of bone infections.

    The disease "osteomyelitis" is characterised by different symptoms and parameters. Decisive roles in the development of the disease are played by the causative bacteria, the route of infection and the individual defense mechanisms of the host. The diagnosis is based on different symptoms and findings from the clinical history, clinical symptoms, laboratory results, diagnostic imaging, microbiological and histopathological analyses. While different osteomyelitis classifications have been published, there is to the best of our knowledge no score that gives information how sure the diagnosis "osteomyelitis" is in general. For any scientific study of a disease a valid definition is essential. We have developed a special osteomyelitis diagnosis score for the reliable classification of clinical, laboratory and technical findings. The score is based on five diagnostic procedures: 1) clinical history and risk factors, 2) clinical examination and laboratory results, 3) diagnostic imaging (ultrasound, radiology, CT, MRI, nuclear medicine and hybrid methods), 4) microbiology, and 5) histopathology. Each diagnostic procedure is related to many individual findings, which are weighted by a score system, in order to achieve a relevant value for each assessment. If the sum of the five diagnostic criteria is 18 or more points, the diagnosis of osteomyelitis can be viewed as "safe" (diagnosis class A). Between 8-17 points the diagnosis is "probable" (diagnosis class B). Less than 8 points means that the diagnosis is "possible, but unlikely" (class C diagnosis). Since each parameter can score six points at a maximum, a reliable diagnosis can only be achieved if at least 3 parameters are scored with 6 points. The osteomyelitis diagnosis score should help to avoid the false description of a clinical presentation as "osteomyelitis". A safe diagnosis is essential for the aetiology, treatment and outcome studies of osteomyelitis. © Georg Thieme Verlag KG Stuttgart · New York.

  17. Tuberculous Pleural Effusion

    2015-01-01

    When a patient presents with new pleural effusion, the diagnosis of tuberculous (TB) pleuritis should be considered. The patient is at risk for developing pulmonary or extrapulmonary TB if the diagnosis is not made. Between 3% and 25% of patients with TB will have TB pleuritis. The incidence of TB pleuritis is higher in patients who are human immunodeficiency virus (HIV)-positive. Pleural fluid is an exudate that usually has a predominance of lymphocytes. The easiest way to diagnose TB pleuritis in a patient with lymphocytic pleural effusion is to demonstrate a pleural fluid adenosine deaminase level above 40 IU/L. The treatment for TB pleuritis is the same as that for pulmonary TB. Tuberculous empyema is a rare occurrence, and the treatment is difficult. PMID:29404070

    We report a case of a 49-year-old female who developed a bronchopneumonia associated with atelectasis of the upper right lobe and back pain of bone origin. Bronchoscopy revealed an endobronchial mass at the origin of the right upper lobe bronchus. Scintigraphy showed three paravertebral spots of the seventh and eighth thoracic vertebrae, without any radiological modification. Culture of lung tissue obtained by trans-parietal punction under CT scan control became positive to Nocardia belonging to the pneumoniae complex. Positive diagnosis of pulmonary nocardiosis associated with two rare localizations was set, one was an endobronchial mass, the other was osteomyelitis of the posterior chest wall. The patient was treated with Trimethoprim ulfamethoxazole and recovered completely. (author)

    Little information is available concerning the natural history and optimal treatment of chronic nonbacterial osteomyelitis (CNO). We conducted a retrospective review to assess the clinical characteristics and treatment responses of a large cohort of pediatric CNO patients. Children diagnosed with CNO at 3 tertiary care centers in the United States between 1985 and 2009 were identified. Their charts were reviewed, and clinical, laboratory, histopathologic, and radiologic data were extracted. Seventy children with CNO (67% female patients) were identified. Median age at onset was 9.6 years (range 3-17), and median follow-up was 1.8 years (range 0-13). Half of the patients had comorbid autoimmune diseases, and 49% had a family history of autoimmunity. Patients with comorbid autoimmune diseases had more bone lesions (P coexisting autoimmunity was a risk factor for multifocal involvement and treatment with immunosuppressive agents. Disease-modifying antirheumatic drugs and biologics were more likely to lead to clinical improvement than NSAIDs.

    Background: Infarctions in tuberculous meningitis (TBM) are common but there is a paucity of studies on MR angiography (MRA). Purpose: To evaluate the pattern and predictors of MRA abnormality in patients with TBM. Material and Methods: Sixty-seven patients with TBM were subjected to clinical, laboratory, magnetic resonance imaging (MRI), and MRA evaluation. The severity of meningitis, focal deficit, CSF findings, and stroke co-morbidities were recorded. Presence of exudates, infarction, hydrocephalous, and tuberculoma on MRI were noted. On intracranial MRA, occlusion or more than 50% narrowing of proximal middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA), and basilar artery were considered abnormal. The MRA abnormality was correlated with clinical, laboratory, and MRI findings. Results: Sixty-seven patients, aged 3-75 years (median 34 years) were included. MRI was abnormal in 61 (91%) patients; basal exudates in 24, hydrocephalous in 23, tuberculoma in 33, and infarction in 40. MRA was abnormal in 34 (50.7%); MCA was most commonly involved (n = 21), followed by PCA (n = 14), ICA (n = 8), ACA (n 5), basilar artery (n = 5), and vertebral and superior cerebellar artery (1 each). One-fourth of the patients had abnormality in both anterior and posterior circulations. MRA abnormality was related to hydrocephalous and infarction; corresponding infarct was present in 61.8% patients; 41.7% patients with abnormal MRA developed infarct at 3 months but none with normal MRA. Conclusion: Half the patients with TBM had MRA abnormality involving both anterior and posterior circulations and 61.8% of them had corresponding infarcts

    Recently, tuberculous meningitis has become rather rare except in areas where tuberculosis is still endemic. Six adolescents and young adults with tuberculous meningitis were evaluated by means of serial computerized tomography (CT), and the results were correlated with the findings of surgical specimens or autopsies. All cases showed meningeal irritation and fever at onset. CSF cultures revealed the presence of tuberculous bacilli. Four cases advanced rapidly to the clinical stage III and expired in a short period-between two weeks to one month from onset. On initial CT scanning, the disappearance of the basal cistern was a characteristic finding in all these cases. With the progression, an enhancement of the basal cistern on contrast injection, a localized hypodensity in adjacent parenchyma, and symmetrical ventricular dilatation appeared. Two autopsied cases showed tuberculous granulomas with purulent materials, thickened meninges, and caseous necrosis in the parenchyma around the basal cistern. The other two cases progressed rather slowly. CT findings at Stage II showed multiple enhanced spots in the basal subcortical area following contrast injection. Tuberculous granulomas were identified in these parts by means of explorative craniotomy. The authors point out the pathognomonic CT findings of tuberculous meningitis and emphasize the necessity of serial CT for the early detection and management of tuberculous meningitis. (author)

  2. Tuberculous Lymphadenitis and Parotitis.

    Cataño, Juan Carlos; Robledo, Jaime

    2016-12-01

    Tuberculous lymphadenitis is the most common extrapulmonary manifestation of disseminated tuberculosis (TB). It is considered to be the local manifestation of the systemic disease that has disseminated to local lymph nodes, but a high index of suspicion is needed for the diagnosis, because there are several infectious and noninfectious diseases that can mimic the same clinical picture. In recent years, different diagnostic methods have been introduced, including fine-needle aspiration cytology, which has emerged as a simple outpatient diagnostic procedure that replaced the complete excisional node biopsy, and a number of molecular methods which have greatly improved diagnostic accuracy. This chapter covers the most actual knowledge in terms of epidemiology, clinical manifestations, pathogenesis, and treatment and emphasizes current trends in diagnosis of tuberculous lymphadenitis. TB parotid gland involvement is extremely rare, even in countries in which TB is endemic. Because of the clinical similarity, parotid malignancy and other forms of parotid inflammatory disease always take priority over the rarely encountered TB parotitis when it comes to differential diagnosis. As a result, clinicians often fail to make a timely diagnosis of TB parotitis when facing a patient with a slowly growing parotid lump. This chapter highlights the most important features of this uncommon disease.

    Osteomyelitis of the clavicle is an uncommon disease, but it should be considered in patients who present with pain, cellulitis, or drainage in the sternoclavicular area following head and neck surgery, irradiation, subclavian vein catheterization, or immunosuppression. An idiopathic presentation is possible. In contrast to primary osteomyelitis of the clavicle, which is occasionally seen in children, secondary osteomyelitis is quite rare. It is often mistaken for a fracture or a possible neoplasm on plain x-rays. Tomograms and CT scanning are confirmatory, and in early cases, technetium-99m bone scanning can be helpful. Treatment must include early, aggressive surgical debridement of all affected tissues, followed by wound coverage with a well-vascularized flap and perioperative antibiotics

    Osteomyelitis of the craniofacial skeleton is rare, with fungal pathogens least commonly implicated. The authors present 2 patients of osteomyelitis of the skull caused by Aspergillus spp. and discuss the diagnosis, clinicopathological course, and management strategies.Late recurrence seen in this type of infection warrants long-term follow-up and a high index of suspicion for the clinical signs associated with recurrence.Such patients would benefit from their surgical debridement being planned and managed via a specialist craniofacial unit, so as to utilize the most aesthetically sensitive approach and the experience of specialists from several surgical disciplines.

    1981-01-01

    A case in which several imaging procedures suggested juvenile Gaucher disease in a child who presented with symptomatology of osteomyelitis is discussed. The 20-month girl was given a Technetium-99m radionuclide skeletal examination which revealed intense uptake of tracer agents along the shaft of the right femur. It was also found that the liver and spleen were dramatically Ga-67 avid. The bone pain symptomatology suggested an osteomyelitis of the femur, but skeletal scintigraphy with Tc-99m-labeled bone tracer demonstrated photopenic areas involving the femur, suggesting that the bone pain may have been due to marrow packed with Gaucher cells. This overexpansion of the marrow may lead to microfractures with remodeling seen radiographically as periosteal new bone and scintigraphically as increased periosteal deposition of tracer agent. The radiogallium study was useful to exclude an underlying osteomyelitis in the involved femurs. Although juvenile Gaucher disease is unusual, it should be considered in any child who presents with the constellation of hepatosplenomegaly and bone pain simulating osteomyelitis

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

    Tuberculous spondylodiscitis can be difficult to diagnose because of its nonspecific symptoms and the similarities with non-tubercular forms of spinal infection. Fluorine-18-fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG PET-CT) is increasingly used for the diagnosis and monitoring of tubercular diseases. Retrospective, case-control study comparing tuberculous spondylodiscitis with biopsy-confirmed pyogenic spondylodiscitis in the period 2010-2012. Ten cases of tuberculous spondylodiscitis and 20 controls were included. Compared to pyogenic, tuberculous spondylodiscitis was more frequent in younger patients (P = 0.01) and was more often associated with thoraco-lumbar tract lesions (P = 0.01) and multiple vertebral involvement (P = 0.01). Significantly higher maximum standardized uptake values (SUV) at FDG-PET were displayed by tuberculous spondylodiscitis compared to controls (12.4 vs. 7.3, P = 0.003). SUV levels above 8 showed the highest value of specificity (0.80). Mean SUV reduction of 48% was detected for tuberculous spondylodiscitis at 1-month follow-up. Higher SUV levels at FDG-PET were detected in tuberculous compared with pyogenic spondylodiscitis. PET-CT use appeared useful in the disease follow-up after treatment initiation. (orig.)

    Osteomyelitis of the skull base is the most severe form of malignant otitis externa. As a result of having treated 13 patients with skull base osteomyelitis over a 4-year period, we have developed a method of staging and monitoring this malady using gallium and technetium scanning techniques. Stage I is localized to soft tissues, stage II is limited osteomyelitis, and stage III represents extensive skull base osteomyelitis. All stages are treated with appropriate antipseudomonal antibiotics. The duration of therapy depends upon the clearing of inflammation as shown on the gallium scan. Each case must be looked at independently and not subjected to an arbitrary treatment protocol

    Tuberculosis is a global health problem that is especially prevalent in developing countries such as India. Recently, atypical presentation has become more common and a high index of suspicion is essential. This study analysed the various presenting symptoms and signs of tuberculous otitis media and the role of diagnostic tests, with the aim of formulating criteria for the diagnosis. A total of 502 patients underwent tympanomastoidectomy over a two-year period. Microbiological and histopathological examinations and polymerase chain reaction analysis of tissue taken during tympanomastoidectomy were performed. A total of 25 patients (5 per cent) were diagnosed with tuberculous otitis media. Severe mixed hearing loss, facial palsy, labyrinthine fistula, post-aural fistula, perichondritis and extradural abscess were noted. There seems to be a resurgence in tuberculous otitis media in India. Microbiological, histopathological and polymerase chain reaction tests for tuberculosis are helpful for its diagnosis.

    Cervical tuberculous adenitis is being seen with increasing frequency in the United States; in the appropriate clinical setting it should be included in the differential diagnosis of an asymptomatic neck mass. Patients are typically young adults who are recent arrivals from Southeast Asia. A history of tuberculosis is not always elicited nor is the chest radiograph always abnormal. All of these patients have positive purified protein derivative tests unless they are anergic. The CT findings may lead to the diagnosis. Several CT patterns of nodal disease can be seen in tuberculous adenitis; some may mimic benign and neoplastic disease. The presence of a multiloculated or multichambered (conglomerate nodal) mass with central lucency and thick rims of enhancement and minimally effaced fascial planes is highly suggestive of tuberculous adenitis, especially if the patient has a strongly positive tuberculosis skin test.

    Twenty-seven Nigerian infants with osteomyelitis are presented during the first 28 days of life to highlight the severity of the clinical manifestations and the radiological features of this infection. The clinical signs include limitation of movement of the extremities involved and localised swelling. Severe constitutional changes such as fever (>39/sup 0/C) and abdominal distension were common. This contrasts with results from North America and Europe which emphasize the paucity of clinical signs despite involvement of multiple sites. Multiple site involvement was encountered in only eight cases. Staphylococcus aureus, proteus mirabilis and candida albicans were the main pathogens isolated. The long bones were more frequently affected. Aggressive bone destruction was a constant radiological finding peculiar to Staphylococcal osteomyelitis while the formation of Sequestrum, are rare occurrence in the newborn, was present in six patients. The mortality rate was 7.4% and the morbidity rate was equally low.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an unusual clinical entity. More than 200 cases are described in the literature and it is presented here with special reference to its radiological aspects. It is an acquired disease of the skeleton which occurs predominantly during childhood and adolescence. About ten per cent of cases begin in early or, rarely, in later adult life. This variant is described here for the first time and is discussed as 'adult CRMO'. The underlying pathology is a bland, predominantly lympho-plasma cellular osteomyelitis which is self-limiting and leads to bone sclerosis (Garre). It probably involves an abnormal immune process which follows an infection but remains clinically latent and remains aseptic and sterile. In a quarter of cases there is an association with pustulosis palmo-plantaris and its relationship with psoriatic arthropathy is discussed. The clinical, histopathological and imaging features (radiological and particularly MRT) and the bone changes are described. (orig./AJ) [de

    Sonograms in forty two patients with tuberculous peritonitis of the wet-ascitic type were retrospectively analyzed. The ascites was clear in 24 patients (57%). There were septations, membranes and debris in 6 (14%), floating debris in 5 (12%), mobile strands or membranes in 4 (10%), and fixed septations in three(7%). Other findings were increased hepatic echogenicity, hepatosplenomegaly, pleural effusion, omental cake, thickened mesentery with adherent bowel loops, lymphadenopathy, thickening of the ileal wall, presented in order of frequency. The ultrasonographic findings are not specific for tuberculous peritonitis, but may give profitable information and protect the patient from unnecessary laparotomy

Chest radiography(n=62), bronchograms(n=18), and CT scans(n=52) of 37 patients with TBB and 25 patients with NTBB were reviewed retrospectively. Diagnostic basis for TBB were positive sputum AFB with or without history of anti-tuberculous chemotherapy(n=35), and radiological findings of pulmonary tuberculous(n=2). Four of NTBB had a history of severe respiratory tract infection in childhood. Air-fluid levels on chest radiographs were seen in 2% of TBB, and 20% of NTBB. On bronchograms, all patients with TBB had combined focal bronchostenosis, whereas patients with NTBB had tubular(50%), cystic(17%), or mixed(33%) pattern of dilatation without stenosis. On CT scans, focal emphysema was seen in 86% of the patients with TBB, and 38% of the patients with NTBB. Peribronchiolar infiltration were seen in 78% and 44% of patients with TBB and NTBB, retrospectively. Basic radiological difference between TBB and NTBB was that the former had coexistent stenosis

    Stroke in tuberculous meningitis (TBM) occurs in 15-57% of patients especially in advance stage and severe illness. The majority of strokes may be asymptomatic because of being in a silent area, deep coma or associated pathology such as spinal arachnoiditis or tuberculoma. Methods of evaluation also influence the frequency of stroke. MRI is more sensitive in detecting acute (DWI) and chronic (T2, FLAIR) stroke. Most of the strokes in TBM are multiple, bilateral and located in the basal ganglia especially the 'tubercular zone' which comprises of the caudate, anterior thalamus, anterior limb and genu of the internal capsule. These are attributed to the involvement of medial striate, thalamotuberal and thalamostriate arteries which are embedded in exudates and likely to be stretched by a coexistent hydrocephalus. Cortical stroke can also occur due to the involvement of proximal portion of the middle, anterior and posterior cerebral arteries as well as the supraclinoid portion of the internal carotid and basilar arteries which are documented in MRI, angiography and autopsy studies. Arteritis is more common than infarction in autopsy study. The role of cytokines especially tumor necrosis factor (TNFα), vascular endothelial growth factor (VEGF) and matrix metaloproteineases (MMPs) in damaging the blood brain barrier, attracting leucocytes and release of vasoactive autocoids have been suggested. The prothrombotic state may also contribute to stroke in TBM. Corticosteroids with antitubercular therapy were thought to reduce mortality and morbidity but their role in reducing strokes has not been proven. Aspirin also reduces mortality and its role in reducing stroke in TBM needs further studies. Copyright © 2010 Elsevier B.V. All rights reserved.

    To determine frequencies of different MRI patterns of tuberculous spondylitisin a public sector hospital in Karachi. This descriptive multidisciplinary case series study was done from October 25, 2011 to May 28, 2012 in Radiology Department and Department of Medicine in the Jinnah Postgraduate Medical Center Karachi. MRI scans (dorsal / lumbosacral spine) of the Patients presenting with backache in Medical OPD, were performed in Radiology Department. Axial and sagittal images of T1 weighted, T2 weighted and STIR sequences of the affected region were taken. A total of 140 patients who were diagnosed as having tuberculous spondylitis were further evaluated and analyzed for having different patterns of involvement of the spine and compared with similar studies. Among frequencies of different MRI pattern of tuberculous spondylitis, contiguous vertebral involvement was 100%, discal involvement 98.6%, paravertebral abscess 92.1% cases, epidural abscess 91.4%, spinal cord / thecal sac compression 89.3%, vertebral collapse 72.9%, gibbus deformity 42.9% and psoas abscess 36.4%. Contiguous vertebral involvement was commonest MRI pattern, followed by disk involvement, paravertebral & epidural abscesses, thecal sac compression and vertebral collapse.

  3. Role of radiopharmaceuticals in detection of osteomyelitis

    Osteomyelitis can present as a significant diagnostic problem in medicine. Knowledge of the presence and extent of infection involving bone is important in determining treatment. In this paper the authors review the role played by radiopharmaceutical techniques in establishing the diagnosis of osteomyelitis. Osteomyelitis has been recognized as one of the most serious complications of emergency surgery to repair severe bone trauma. It is also a complication of surgery for prosthesis placement. In still other instances, osteomyelitis can be of hematogenous origin, without a major wound site. Unlike other infections, it rarely presents with acute symptoms. Osteomyelitis is divided into two categories that are time related: acute, in which clinical signs and symptoms of bone infection have been present for less than 1 month, and chronic, in which symptoms have been present for more than 1 month. The acute type is usually caused by Staphylococcus aureus in children (often secondary to skin infection), whereas in adults it can be secondary to intravenous drug abuse. Predisposing factors such as diabetes mellitus, peripheral vascular disease, and sickle cell disease are important to the outcome of osteomyelitis. One way to determine the microbe causing the infection is direct bone biopsy from the site of suspected osteomyelitis. There is one important limitation for needle biopsy in the diagnosis of osteomyelitis. Biopsies are contraindicated in the small bones of the hands and feet, because of risk of pathologic fracture (and may be relatively contraindicated after diphosphonate therapy and loss of bone mineral)

    Five cases of chronic, inflammatory, multifocal bone lesions of unknown etiology are reported. Although bone biopsy confirmed osteomyelitis in each case in none of them were organisms found inspite of an extensive work up. Different clinical course of the disease reflects different aetiology in respective cases. These cases present changing aspects of osteomyelitis emerging since introduction of antibiotics. (orig.)

    1986-01-01

    A case has been presented of tuberculous spondylitis in a 41-year-old woman from Saudi Arabia. CT studies, demonstrating large exostoses projecting from the involved fourth lumbar vertebral body, were obtained nine months after treatment was given for tuberculous spondylitis. The CT scans obtained before and after treatment showed significant change between the two studies nine months apart. The large psoas abscesses and the the abscesses tracking longitudinally beneath the anterior spinal ligament at the time of the initial involvement were demonstrated dramatically. A plain film of the lumbar spine before treatment showed involvement of the vertebral bodies of L3 and L4 as well as the intervening disk cartilage. The differential diagnosis in such a pattern of osteophytosis was considered. The issue of hyperostosis developing in tuberculous spondylitis and the possible cause were discussed and the authors speculated that the chronicity of the tuberculous process permits reparative woven bone to be deposited on the scaffolding of dead bone, thus giving a sclerotic appearance which is secondary to ischemic necrosis of the affected bone. The authors also stressed that the extreme hyperostosis in this case may relate to successful chemotherapy. According to the authors no previous report of such changes as demonstrated on CT following successful chemotherapy are available in the literature. (orig.)

    When tuberculous pneumonia appears as a segmental or loabr consolidation, its is difficult to differentiate tuberculous pneumonia from nontuberculous bacterial pneumonia radiologically. The object of this study was to define the typical radiographic findings of tuberculous pneumonia through comparative analysis of tuberculous and nontuberculous pneumonia. A review of chest radiolograph in 29 patients with tuberculous pneumonia and in 23 patients with nontuberculous bacterial pneumonia was made with regard to homogeneity, volume loss, air-fluid level within the cavities, air-bronchogram, pleural disease, and predilection sites. The characteristic findings of tuberculous pneumonia are a heterogeneous density of infiltration (66%), evidence of volume loss of infiltrative lesion (52%), and cavity formation (48%) without air - fluid level. An associated parameter of analysis is the relative absence of leukocytosis (76%)

    Computed tomography (CT) scans were performed in 17 adults with osteomyelitis of the spine. The dominant features were paravertebral soft-tissue swelling, abscess formation, and bone erosion. In two patients there were no findings indicative of osteomyelitis on conventional radiographs, but CT revealed paravertebral abscesses and bone lysis, helping to establish the diagnosis of osteomyelitis, chiefly because of its ability to detect early erosion of spongy vertabral bone, disk involvement, paravertebral soft-tissue swelling or abscess, and extension of the pathology into the spinal canal. Furthermore, CT facilitated closed-needle biopsy, helping to establish the pathologic diagnosis

    Genitourinary tuberculosis is a common type of extra-pulmonary tuberculosis . The kidneys, ureter, bladder or genital organs are usually involved. Tuberculosis of the prostate has mainly been described in immune-compromised patients. However, it can exceptionally be found as an isolated lesion in immune-competent patients. Tuberculosis of the prostate may be difficult to differentiate from carcinoma of the prostate and the chronic prostatitis when the prostate is hard and nodular on digital rectal examination and the urine is negative for tuberculosis bacilli. In many cases, a diagnosis of tuberculous prostatitis is made by the pathologist, or the disease is found incidentally after transurethral resection. Therefore, suspicion of tuberculous prostatitis requires a confirmatory biopsy of the prostate. We report the case of 60-year-old man who presented a low urinary tract syndrome. After clinical and biological examination, and imaging, prostate cancer was highly suspected. Transrectal needle biopsy of the prostate was performed and histological examination showed tuberculosis lesions.

    Full Text Available Osteomyelitis is an infection of the bone or bone marrow, usually caused by pyogenic bacteria or mycobacterium. Osteomyelitis, inflammatory process of the bone and its structures, can be acute or chronic. Taking a journey from a nonsurgical approach to a surgical one, it appeared to be one osteomyelitis revenge against all our efforts. The pain, the pus, the new bone formation, and all the trouble, this case showed it all. The injudicious use of antibiotics and delay in providing the requisite treatment can cause devastating effects as in the case of an 11-year-old child. A case report on treating osteomyelitis through medication and realizing that surgical excision remains the only realistic approach, the report talks about the investigations and treatment planning done to deal with it.

    Periostitis and osteomyelitis can occur in drug addicts not only by hematogeneous dissemination of the infecting organisms, but as a result of introduction of bacteria by direct injection into periosteum or injection through infected skin and subcutaneous tissues. A spectrum of examples of osteomyelitis of the bones of the forearm in drug addicts is presented to illustrate this phenomenon. Neglect of these infections and the trauma of continued injections can lead to extensive tissue and bone loss. (orig.)

    1986-01-01

    Spinal tuberculosis is curable disease, and early diagnosis is mandatory for early treatment. We reviewed conventional radiographers and computed tomograms (CT) from Histopathologically confirmed 30 cases of spinal tuberculosis, and compared these findings with radiologic findings from 2 cases of pyogenic spondylitis and 4 cases of metastasis. The results were as follows: 1. The frequent site of involvement were thromboembolic junction and low lumbar vertebrae, and the most frequent type is multisegmented subligamentous type (93.3%). 2. CT was not of great use in the differential diagnosis of the tuberculosis. Dominant CT findings of tuberculous spondylitis were anterior vertebral body destruction, paravertebral soft-tissue mass and thick walled abscess formation occasionally containing calcification and disc space narrowing in the setting of an indolent or relatively benign course. 3. CT is the best modality for imaging the extent and anatomy of the destructive process, the degree of canal encroachment, and the change of adjacent vital structure. So CT was particularly useful in pre-operative planning of debridement and stabilization surgery. 4. The most common causes of neurologic manifestations in tuberculous spondylitis were the compression of spinal cord by sequestrated bony fragments and disc material, granulation tissue or abscess in the spinal canal.

    Images obtained with various modalities in 17 patients with Brucella spondylitis and 12 patients with tuberculous spondylitis were analyzed in order to identify distinguishing features. All patients underwent radiography, 21 underwent bone scintigraphy, and all underwent high-resolution CT and/or MR imaging. Characteristic findings in Brucella spondylitis included a predilection for the lumbar spine, bone destruction limited to the end-plates and associated with sclerosis, and disk space collapse (16 of 19) with disk vacuum phenomenon in eight and localized soft-tissue edema. MR imaging showed diffuse increased signal in vertebrae, disks, and adjacent soft tissues on long repetition time/long echo time studies (four patients). Tuberculosis spondylitis was characterized by a midthoracic predilection, diffuse vertebral destruction with gibbus deformity, severe disk collapse, and extensive paraspinal abscesses. MR imaging findings (three patients) were similar to but more severe than findings in Brucella spondylitis

    To evaluate the efficacy of magnetic resonance imaging (MRI) for distinguishing tuberculosis from other types of meningoencephalitis. MRIs of 100 patients with tuberculous (50), pyogenic (33), viral (14), or fungal (3) meningoencephalitis were analyzed independently by 2 radiologists. Number, size, location, signal characteristics, surrounding edema, and contrast enhancement pattern of nodular lesions; location and pattern of meningeal enhancement; extent of infarct or encephalitis and hydrocephalus were evaluated. Contrast-enhancing nodular lesions were detected in patients with tuberculous (43 of 50 patients), pyogenic (9 of 33), and fungal (3 of 3) infections. No nodules were detected in patients with viral meningoencephalitis. Using the criteria of 1 or more solid rim or homogeneously enhancing nodules smaller than 2 cm, the sensitivity, specificity and accuracy for diagnosing tuberculous meningitis were 86.0%, 90.0% and 88.0%, respectively. Magnetic resonance imaging is useful in distinguishing tuberculous from pyogenic, viral and fungal meningoencephalitis. (author)

    Full Text Available In recent years the significant deterioration of health has been observed in schoolchildren. As per official data only 20% of children graduating from school are considered to be completely healthy, and 60% suffer from chronic diseases, i.e. belong to health groups III, IV and V, among which there are many children belonging to tuberculosis risk groups and suffering from undetected latent tuberculous infection. The efficiency of the new technique aimed to detect active tuberculous infection in children and adolescents of health groups III, IV and V has been evaluated. Screening proved the reduction in the number of patients in need of TB doctor advising by 8.4 fold compared to traditional mass diagnostics with tuberculin. Hyperergic reactions to diaskintest are 6 fold less common compared to Mantoux test. And 99.2% of children referred to TB doctor were registered to the dispensary follow-up versus 23.4% of children referred to TB doctor as per mass tuberculin testing results. (p < 0.001. Thus the validity of referral to TB doctor increased 4.2 fold. The detection rate of active forms of tuberculosis made 0.4 per 1000 examinations versus 0.1 in case of mass screening with tuberculin testing.

    Full Text Available A healthy male farm employee developed an unusual infection caused by Pasteurella multocida. Atypical features included the chronic nature of the infection, the development of osteomyelitis of the tibia without direct animal inoculation, and lack of fever and leukocytosis. Radiographic appearance of P multocida osteomyelitis may be the result of osteoclast activation and can be confused with musculoskeletal tumour. P multocida infection requires a high degree of suspicion, and should be considered in cases of farm- or animal-related injuries even if there is no history of direct animal contact.

    We present ultrasound (US) and computed tomography (CT) findings in 7 patients with periportal and peripancreatic tuberculous adenitis. In US scans, hypoechoic adenopathies were found in 6 patients while in the other one a hypoechoic, poorly marginated mass was seen. CT studies showed hypodense (25-35 HU) enlarged lymph nodes with immediate postcontrast peripheral rim enhancement in 3 patients. An infiltrating inhomogeneous mass was present in other patient and soft tissue density lobulated masses were found in delayed postcontrast scans of 2 patients. The US findings are of no help in distinguishing tuberculosis from other causes of adenitis. The CT appearance has been variable and only the hypodense nodes with peripheral enhancement in postcontrast scans are suggestive of this entity. (orig.) [de

    2013-06-01

    Full Text Available Spondylodiscitis represents 2%–4% of all bone infections cases. The correct diagnosis and appropriate treatment can prevent complications such as vertebral collapse and spinal cord compression, avoiding surgical procedures. The diagnosis is based on characteristic clinical and radiographic findings and confirmed by blood culture and biopsy of the disc or the vertebra. The present study was developed with Clementino Fraga Filho University Hospital patients with histopathologically and microbiologically confirmed diagnosis of spondylodiscitis, submitted to magnetic resonance imaging of the affected regions. In most cases, pyogenic spondylodiscitis affects the lumbar spine. The following findings are suggestive of the diagnosis: segmental involvement; ill-defined abscesses; early intervertebral disc involvement; homogeneous vertebral bodies and intervertebral discs involvement. Tuberculous spondylodiscitis affects preferentially the thoracic spine. Most suggestive signs include: presence of well-defined and thin-walled abscess; multisegmental, subligamentous involvement; heterogeneous involvement of vertebral bodies; and relative sparing of intervertebral discs. The present pictorial essay is aimed at showing the main magnetic resonance imaging findings of pyogenic and tuberculous discitis.

Our study was a retrospective analysis and compared the characteristics of confirmed pleural infection by common bacteria (PIB) and that due to pleural tuberculosis (PT). For the PIB, the signs evolved for 2.4 ± 1.4 weeks versus 5.6 ± 2.2 weeks for the PT (P=0.01). In multivariate analysis, for PIB the onset of symptoms was more abrupt (OR=3.8 [1.5; 9.9]; P=0.01), asthenia was less frequent (OR=0.3 [0.1; 0.9]; P=0.03), pleural liquid was more purulent (OR=40.0 [15.0; 106.7]; Ppleural effusions caused by tuberculosis (TB) and those due to other bacterial infections. However, they are not sufficiently sensitive and therefore the search for the tuberculous bacillus must be systematic while waiting for implementation of new diagnostic tests for the organism.

    1998-01-01

    To analyze the radiological signs and clinical presentation of tuberculous bursitis arising in the ischial and trochanteric territories, given the limited available knowledge on these entities and in view of the growing prominence of extra pulmonary tuberculosis (TB) in the field of infectious diseases. We present seven cases dealt with in our hospital from the first medical consultation to the definitive diagnosis and treatment. Five of the patients presented greater trochanter involvement, while ischium was the site in the remaining two, in one of whom the bursitis extended toward pubis. The radiographic images revealed demineralization and/or erosion of the bone surface in six cases, soft tissue calcification in four, soft tissue mass in two, coccygeal involvement in one and avulsion of a bone fragment one. An ultrasound study was carried out in a of case soft tissue abscess and fistulography in a case of peri-ischial abscess reaching the cutaneous level. Images of the ischial and trochanteric tuberosities such as those described in the present report should lead to a suspicion of bursitis accompanied by local osteitis. One of the etiologies that should be considered, probably the most common one, is tuberculosis, given the serious consequences that poor initial management would have (if is often treated as pyogenic) and its growing incidence.

    To determine the age distribution, gender, incidence, and imaging findings of vertebral chondroblastoma, and to compare our series with findings from case reports in the world literature.Design and patients Case records and imaging findings of nine histologically documented vertebral chondroblastomas were retrospectively reviewed for patient age, gender, vertebral column location and level, morphology, matrix, edema, soft tissue mass, spinal canal invasion, and metastases. Our findings were compared with a total of nine patients identified from previous publications in the world literature. The histologic findings in our cases was re-reviewed for diagnosis and specifically for features of calcification and secondary aneurysmal bone cyst (ABC). Clinical follow-up was requested from referring institutions. Nine of 856 chondroblastomas arose in vertebrae (incidence 1.4%; thoracic 5, lumbar 1, cervical 2, sacral 1). There were six males and three females ranging in age from 5 to 41 years (mean 28 years). Satisfactory imaging from seven patients revealed the tumor to arise from the posterior elements in four and the body in three. All tumors were expansive, six of seven were aggressive, and the spinal canal was significantly narrowed by bone or soft tissue mass in six. In one patient canal invasion was minimal. Calcification was pronounced in two and subtle in four. The sole nonaggressive-appearing tumor was heavily mineralized. Bony edema and secondary ABC were not seen on MR imaging. None of the cases had microscopic features of significant secondary ABC. Calcification, and specifically ''chicken wire'' calcification, was identified in two patients. Pulmonary metastases occurred in none. Vertebral chondroblastoma is a rare neoplasm that presents later in life than its appendicular counterpart.

    Full Text Available Osteomyelitis is designated to a variety of bone diseases having inflammation as a common denominator. Persistent infection progresses to inflammation of marrow space, haversian system and periostium of affected region. Thrombosis of endothelial vessels cause necrosis and sequestrum formation. Both pyogenic and nonpyogenic infections of jaw lead to this condition. Immunosuppressed patients are more prone to mycelial infections, whereas their occurrence in immunocompetent individuals are highly unusual.

    Although osteomyelitis of the inferior maxilla is still relatively frequently diagnosed, manifestation of the disease in the temporomaxillary joint is a rare occurrence. The symptomatology, diagnosis, and therapy of this particular arthropathy is discussed by reference to three cases treated in recent years at the Berlin Clinic of Maxillofacial Surgery. The importance of an early diagnosis and therapy is directed attention to because of the danger of serious subsequent diseases that may result in the loss of vital functions.

    Diabetic foot osteomyelitis therapeutical options are based on antibiotic therapy and surgical resection of the infected bone(s). Surgical and medical approaches of patients suffering from a diabetic foot osteomyelitis do not oppose but are complementary and need to be discussed as a tailored manner. Areas covered: The aim of the present article is to discuss data issued from the most recent guidelines of the Infectious Diseases Society of America and the International Working Group on the Diabetic Foot on the management of the diabetic foot infection and from a search in the current literature using the terms diabetic foot osteomyelitis and treatment/therapy/therapeutical in both PubMed and Medline, restricted to the last five years. Expert opinion: Surgical removal of the entire infected bone(s) has been considered in the past as the standard treatment but medical approach of these patients has now proven efficacy in selected situations. The current emergence of bacteria, especially among Gram negative rods, resistant to almost all the available antibiotics gradually augments the complexity of the management of these patients and is likely to decrease the place of the medical approach and to worsen the outcome of these infections in the next future.

    Parotitis is a common occurrence in the immunocompromised, dehydrated, and malnourished patient as a result of dysfunctional ductal and parotid cells. Inflammation can be acute or chronic based on clinical history, and it can be suppurative based on the presence of micro or macro abscess formation within the substance of the gland. This report presents a case of concomitant condylar osteomyelitis and chronic suppurative parotitis in the setting of previous methicillin-susceptible Staphylococcus aureus foot infection. Ultimately, resection of osteomyelitis, drainage of parotid infection, and intravenous antibiotic therapy led to full resolution of the infection and symptoms. The final pathology of osteomyelitis of the temporomandibular joint and methicillin-resistant S aureus infection is an unusual consequence of chronic parotitis. The patient was restored with a total joint replacement approximately 3 months after resection with no recurrence of infection after 24 months.

  7. Osteomyelitis and Osteonecrosis in Inflammatory Bowel Disease

    Directory of Open Access Journals (Sweden)

    Hugh J Freeman

    1997-01-01

    Full Text Available Osteomyelitis and osteonecrosis are skeletal disorders seen in patients with inflammatory bowel disease (IBD. Osteomyelitis usually occurs in the pelvic bones, especially in complicated Crohn's disease, presumably by direct extension from a pelvic inflammatory mass, abscess or fistulous tract. Diagnosis of osteomyelitis may be difficult and can lead to spinal extension of the septic process with a resultant neurological deficit, including paraplegia. Osteonecrosis or avascular necrosis has been reported in patients with either ulcerative colitis or Crohn's disease, often, but not exclusively, during or following steroid treatment. The disease is often multifocal, but its natural history is unknown, especially if diagnosed early with modern imaging methods, such as magnetic resonance. In IBD patients, the relationship between osteonecrosis and steroid use is unknown. An adverse steroid effect on bones, especially the femoral heads, may develop in some patients with IBD but, to date, this hypothesis remains unproven. Critical evaluation of published data reveals no consistent association between osteonecrosis and steroid treatment in IBD patients.

    Full Text Available Ketan C Pande Raja Isteri Pengiran Anak Saleha Hospital, Bandar Seri Begawan, BruneiAbstract: Chronic osteomyelitis is a challenging condition to treat. It is seen mostly after open fractures or in implant-related infections following treatment of fractures and prosthetic joint replacements. Recurrence of infection is well known, and successful treatment requires a multidisciplinary team approach with surgical debridement and appropriate antimicrobial therapy as the cornerstone of treatment. Staging of the disease and identification of the causative microorganism is essential before initiation of treatment. Important surgical steps include radical debridement of necrotic and devitalized tissue, removal of implants, management of resultant dead space, soft-tissue coverage, and skeletal stabilization or management of skeletal defects. The route of administration and duration of antimicrobial therapy continues to be debated. The role of biofilm is now clearly established in the chronicity of bone infection, and newer modalities are being developed to address various issues related to biofilm formation. The present review addresses various aspects of chronic osteomyelitis of long bones seen in adults, with a review of recent developments.

    To analyze the related sonographic findings and to determine the value of sonography in establishing the diagnosis of acute osteomyelitis in infants. The sonographic findings of eleven infants aged 10 days-4 months (mean, 45 days) with acute osteomyelitis were retrospectively evaluated. The involved bones were the femur (n=5), humerus (n=2), tibia (n=2), rib(n=1), sternum (n=1), and calcaneus (n=1). Discontinuity or destruction of cortical margins, echotexture of the metaphysis and epiphysis, the presence of subperiosteal hypoechoic lesion, adjacent soft tissue swelling, distension of the joint capsule, the echotexture of joint effusion, and dislocation or subluxation of the involved joint were evaluated. The sonographic findings were compared with the plain radiographic (n=12) and MR (n=5) findings, with special attention to the identification of the metaphyseal or epiphyseal bony lesions and the involvement of adjacent joints. The sonographic findings of osteomyelitis were cortical discontinuity or destruction (n=12), hypoechoic lesions with an echogenic rim in the metaphysis (n=12), subperiosteal hypoechoic lesions (n=8), soft tissue swelling (n=9), a distended hip joint, with echogenic fluid (n=5), ill-demarcated echogenic lesions in the capital femoral epiphysis (n=5), and a subluxated hip joint (n=3). Plain radiographs revealed well or ill-defined osteolytic lesions in the metaphysis, accompanied by cortical destruction (n=8), new periosteal bone formation (n=3) and reactive sclerosis (n=2). Abnormality of the femoral epiphyses and joint involvement were not detected on plain radiographs, and in four cases no abnormality was noted. MR imaging showed that at T1WI, affected bony lesions were of low signal intensity and enhaned, with high signal intensity at T2WI. In all cases, both metaphyseal and epiphyseal lesions were demonstrated at MRI, but in one of the three cases in which an epiphyseal lesion was seen at MRI, this was not detected at US.

    The sparsity of publication concerning CT findings of tuberculous arthritis prompted authors to retrospectively evaluate 12 patients with tuberculous arthritis for characteristic CT findings. In each patients, the diagnosis of tuberculous arthritis was confirmed by surgery or biopsy. The CT examinations were evaluated by two radiologists retrospectively. Involved joints were the hip joint in seven patients, the sacroiliac joint in three patients, and the shoulder and ankle joint in one patient each. CT features included subchondral bony erosion(12 patients), soft tissue mass in the joint space(nine), widening of the joint space(eight), ipsilateral music atrophy(eight), thickening of the joint capsule(seven), intra-articular effusion(six), soft tissue abscess(five), and bony sclerosis(four). In seven patients with the duration of symptoms less than 1 year, thickening of joint capsule and intra-articular effusion were the predominant findings, while bony sclerosis, gross bone destruction, and soft tissue mass in joint space were seen in five patients with the duration of symptoms longer than 1 year. Our results indicate that CT is useful in the diagnosis of tuberculous arthritis by demonstrating characteristic pathologic changes of the joint space, soft tissue abnormality and bony involvement

    Several MRI investigations for detecting or excluding acute and non-post-traumatic chronic osteomyelitis were performed in 31 children, osteomyelitis was evident in 21 patients. The sensitivity of MRI for osteomyelitis was 90%, and specificity was 100%. In children with confirmed osteomyelitis 23 follow-up investigations were carried out in order to evaluate duration of the medullary edema. In uncomplicated cases only treated by antibiotics edema regression was evident after 4 weeks and completed after 12-16 weeks. In cases in whom extended concomitant soft-tissue infection was depicted regression of edema was prolonged independent of surgical intervention. The study reveals that at onset of acute osteomyelitis in children MRI can replace technetium 99m-labeled scintigraphy and reduce plain-film investigations. The results support the usefulness of MRI in discrimination of isolated soft-tissue infection and noninfectious diseases of bone. (orig.)

    2017-11-01

    A percutaneous antibiotic delivery technique (PAD-T) used for the adjunctive management of osteomyelitis is presented. This surgical technique incorporates a calcium sulfate and hydroxyapatite (calcium phosphate) bone void filler acting as a carrier vehicle with either an antibiotic or an antifungal medicine, delivering this combination directly into the area of osteomyelitis. The benefit of the PAD-T is reviewed with a case presentation of a successfully treated calcaneal osteomyelitis. No previously reported PAD-T using a simple bone cortex incision in the adjunctive treatment of osteomyelitis has been reported. The PAD-T safely and effectively uses a calcium sulfate and hydroxyapatite bone void filler carrier vehicle to deliver either an antibiotic or an antifungal medicine directly into the area of osteomyelitis.

    Surgical treatment of thoracolumbar osteomyelitis consists of radical debridement, reconstruction of anterior column either with or without posterior stabilization. The objective of present study is to evaluate a case series of patients with osteomyelitis of thoracic and lumbar spine treated by single, posterior approach with posterior instrumentation and anterior column reconstruction. Seventeen patients underwent clinical and radiological evaluation pre and postoperatively with latest follow-up at 19 months (8-56 months) after surgery. Parameters assessed were site of infection, causative organism, angle of deformity, blood loss, duration of surgery, ICU stay, deformity correction, time to solid bony fusion, ambulatory status, neurologic status (ASIA impairment scale), and functional outcome (Kirkaldy-Willis criteria). Mean operating time was 207 min and average blood loss 1,150 ml. Patients spent 2 (1-4) days in ICU and were able to walk unaided 1.6 (1-2) days after surgery. Infection receded in all 17 patients postoperatively. Solid bony fusion occurred in 15 out of 17 patients (88 %) on average 6.3 months after surgery. Functional outcome was assessed as excellent or good in 82 % of cases. Average deformity correction was 8 (1-18) degrees, with loss of correction of 4 (0-19) degrees at final follow-up. Single, posterior approach addressing both columns poses safe alternative in treatment of pyogenic vertebral osteomyelitis of thoracic and lumbar spine. It proved to be less invasive resulting in faster postoperative recovery.

    An 8-and-a-half-year-old girl with supernumerary teeth of tuberculate and odontoma type is described. Treatment of the patient is carried out on conventional lines with a combination of surgical and orthodontic methods. The upper tuberculate type supernumerary teeth were extracted and, after surgical exposure, the upper permanent first incisors were aligned with removable appliances. After secondary dentition was completed, the lower odontoma type supernumerary tooth was removed surgically, and also the maxillary and mandibular first premolars were extracted because of severe crowding, and fixed orthodontic appliances were used to align the permanent dentition. Early diagnosis and treatment of this anomaly is necessary to avoid more serious consequences and to prevent severe orthodontic disturbances.

    We report the imaging features of three cases of tuberculous otitis media. All three patients underwent temporal bone CT scanning, and in two, additional MRI scanning was performed. The three cases showed soft tissue density in the external auditory canal, and in two, destruction of the trabeculation and internal cortex of the mastoid bone was noted. In two patients with facial palsy, erosion of the facial canal was seen. On MRI, abundant granulomatous tissue was noted in the middle ear cavity and mastoid air cells. In one case, abnormal enhancement of the cochlea, and of the facial and eighth cranial nerve in the internal acoustic canal was seen. Another case showed enhancement of the vestibule and lateral semicircular canal. If radiologic evaluation of chronic otitis media reveals destruction of the tegmen and trabeculation of the mastoid bone, together with abundant granulation tissue and enhancement of the internal ear, tuberculous otitis media may be included in the differential diagnosis

    Six patients with 7 tuberculous psoas or ilio-psoas abscesses were treated by CT-guided catheter drainage and chemotherapy. The abscesses (5 unilateral and 1 bilateral) were completely drained using a posterior or lateral approach. The abscess volume was 70 to 700 ml (mean 300 ml) and the duration of drainage 5 to 11 days (mean 7 days). Immediate local symptomatic improvement was achieved in all patients, and there were no procedural complications. CT follow-up at 3 to 9 months showed normalization in 5 patients, 2 of whom are still in medical therapy. One patient, who did not take the medication regularly, had a recurrent abscess requiring new catheter drainage after which the fluid collection disappeared. Percutaneous drainage represents an efficient and attractive alternative to surgical drainage as a supplement to medical therapy in the management of patients with large tuberculous psoas abscesses.

    We report the imaging features of three cases of tuberculous otitis media. All three patients underwent temporal bone CT scanning, and in two, additional MRI scanning was performed. The three cases showed soft tissue density in the external auditory canal, and in two, destruction of the trabeculation and internal cortex of the mastoid bone was noted. In two patients with facial palsy, erosion of the facial canal was seen. On MRI, abundant granulomatous tissue was noted in the middle ear cavity and mastoid air cells. In one case, abnormal enhancement of the cochlea, and of the facial and eighth cranial nerve in the internal acoustic canal was seen. Another case showed enhancement of the vestibule and lateral semicircular canal. If radiologic evaluation of chronic otitis media reveals destruction of the tegmen and trabeculation of the mastoid bone, together with abundant granulation tissue and enhancement of the internal ear, tuberculous otitis media may be included in the differential diagnosis.

    5 patients with diabetic-foot were treated by maggot therapy. The most serious case was in a 75-year-old man who had gangrene and osteomyelitis of the right foot. Proteus mirabilis, Enterococcus sp., Providencia stuartii and Staphylococcus spec. (coagulase positive) were isolated from lesions which did not respond to antibiotic therapy. The patient had twice refused amputation but agreed to maggot therapy. Larvae of the sheep blowfly Phoenicia (Lucilia) sericata were used for twice-weekly treatment over a period of 7 months. Sterile larvae were applied to the wound and replaced every 3-4 days. After 4 months of treatment, the necrotic tissue around the toes and on the sole of the foot detached from the healthy tissue. During the last 3 months of treatment the larvae removed the remaining infected tissue. As therapy progressed, new layers of healthy tissue covered the wound. The offensive odor associated with the necrotic tissue and the intense pain in the foot decreased significantly. At the end of therapy, during which there were no complaints of discomfort, he was able to walk. In the 4 other patients who had relatively superficial gangrene, the maggots debrided the wounds within 2-4 weeks. Thereafter treatment was continued with antibiotics. Maggot therapy can be recommended in cases of intractable gangrene and osteomyelitis, when treatment with antibiotics and surgical debridement have failed.

    The clinical diagnosis of osteomyelitis and the diabetic foot is in most of the patients not possible without imaging the bone. The clinical problem is to diagnose infection as early, as reliable and as cheap as possible to prevent the possible longstanding and life-threatening complications. For imaging a lot of different radiological and nuclear medicine methods are available. This article focuses on the possible results of conventional plain radiography and tomography, computed tomography and magnetic resonance imaging as radiological and on bone scan, autologous white blood cell scintigraphy with 111 In-oxin or 99m Tc-HMPAO, antigranulocyte antibodies, 99m Tc/ 111 In-human immunoglobulin, 67 Ga-citrate and 99m Tc-nanocelloids. Different methods after different answers. Radiological methods give detailed pathological answers, nuclear medicine methods answer questions of specificity such as leukocyte infiltration. If osteomyelitis is suspected, plain radiography should be the first, three phase bone scintigraphy the second and infection specific radiopharmaceuticals the third step of examination. Only in negative images with high clinical suspicion CT or MRI should be the final imaging procedure. In the diabetic foot imaging cascade should also start with plain radiography, followed by three phase bone scintigraphy or MRI. If clinically neuropathy is present specific nuclear medicine imaging should be performed

    Skull base osteomyelitis typically presents in an immunocompromised patient with severe otalgia and otorrhoea. Pseudomonas aeruginosa is the commonest pathogenic micro-organism, and reports of resistance to fluoroquinolones are now emerging, complicating management. We reviewed our experience of this condition, and of the local pathogenic organisms. A retrospective review from 2004 to 2011 was performed. Patients were identified by their admission diagnostic code, and computerised records examined. Twenty patients were identified. A facial palsy was present in 12 patients (60 per cent). Blood cultures were uniformly negative, and culture of ear canal granulations was non-diagnostic in 71 per cent of cases. Pseudomonas aeruginosa was isolated in only 10 (50 per cent) cases; one strain was resistant to ciprofloxacin but all were sensitive to ceftazidime. Two cases of fungal skull base osteomyelitis were identified. The mortality rate was 15 per cent. The patients' treatment algorithm is presented. Our treatment algorithm reflects the need for multidisciplinary input, early microbial culture of specimens, appropriate imaging, and prolonged and systemic antimicrobial treatment. Resolution of infection must be confirmed by close follow up and imaging.

    To study the clinical manifestations and outcome of patients with tuberculous sclerokeratitis treated with antituberculous therapy without concomitant use of systemic steroids. We reviewed retrospectively the medical records of eight consecutive patients with tuberculous sclerokeratitis. Patients were treated unsuccessfully with topical and/or systemic steroids. They underwent complete ophthalmic examination, systemic evaluation, laboratory investigations and imaging. Tuberculin skin test was done with purified protein derivative (PPD) on all patients. The diagnosis of tuberculous sclerokeratitis was made based on clinical findings of scleritis with adjacent peripheral corneal stromal keratitis, positive PPD test of 15 mm of induration or more, response to antituberculous treatment (ATT) within 4 weeks and exclusion of other causes of sclerokeratitis. Antituberculous drugs were given for a minimum of 6 months without concomitant use of corticosteroids. The outcome measure was resolution of the ocular surface inflammation of the sclera and cornea. Eight consecutive patients with a diagnosis of tuberculous sclerokeratitis were included. There were one male and seven female patients. The mean age was 29 years with an age range of 7-43 years. The involvement of the sclera was nodular in six patients and diffuse in two. The involvement of the cornea consisted of peripheral corneal stromal inflammation adjacent to the area of scleritis. Patients responded to antituberculous medications with complete resolution of the sclerokeratitis without topical or systemic anti-inflammatory agents. Antituberculous medications can lead to complete resolution of the sclerokeratitis without concomitant use of steroids, or other anti-inflammatory agents.

    To evaluate the CT findings of perihepatic tuberculous abscesses. The CT scans of 11 patients (6 females and 5 males) with 14 pathologically proven perihepatic tuberculous abscess were retrospectively evaluated in terms of the morphological characteristics of the abscesses and changes in other abdominal organs and at other sites. A total of 14 absceses were noted in 11 patients. Six (43%) were in the right subphrenic space, three (21%) in the right perihepatic space, three (21%) in the left subphrenic space, and two (14%) in the left perihepatic space. The right side was predominant. The abscesses ranged in size from 1 to 10 (mean, 5) cm in diameter, with a wall thickness of 2-7 (mean, 3) mm. Of the 14 abscesses, 13 were oval, and one spherical. CT findings were as follows : a smooth abscess margin with even wall thickness in seven of the eleven patients (64%); calcification of the wall in two (18%); internal septa in seven (64%); localized fluid collection in nine (82%); lymphadenopathy in five (45%); and peritoneal enhancement in seven (64%). Lesions suggesting tuberculous infection coexisted at other sites in eight patients. These included the lung in six patients (55%), the neck in three (27%), an axilla in two (18%), the liver in two (18%), the spleen in one (9%), and the gastroin-testinal tract in one (9%). CT scanning is useful for establishing the diagnosis of perihepatic tuberculous abscesses by evaluating the morphological characteristics of the mass and by observing changes in other abdominal organs and at other sites.

    To find and evaluate characteristic magnetic resonance imaging (MRI) patterns for the differentiation between Ewing sarcoma and osteomyelitis. We identified 28 consecutive patients referred to our department for MRI (1.5 T) of an unclear bone lesion with clinical symptoms suggestive of Ewing sarcoma or osteomyelitis. MRI scans were re-evaluated by two experienced radiologists, typical MR imaging features were documented and a diagnostic decision between Ewing sarcoma and osteomyelitis was made. Statistical significance of the association between MRI features and the biopsy-based diagnosis was assessed using Fisher's exact test. The most clear-cut pattern for determining the correct diagnosis was the presence of a sharp and defined margin of the bone lesion, which was found in all patients with Ewing sarcoma, but in none of the patients with osteomyelitis (P < 0.0001). Contrast enhancing soft tissue was present in all cases with Ewing sarcoma and absent in 4 patients with osteomyelitis (P = 0.0103). Cortical destruction was found in all patients with Ewing sarcoma, 4 patients with osteomyelitis did not present any cortical reaction (P = 0.0103). Cystic or necrotic areas were identified in 13 patients with Ewing sarcoma and in 1 patient with osteomyelitis (P = 0.004). Interobserver reliability was very good (kappa = 1) in Ewing sarcoma and moderate (kappa = 0.6) in patients with osteomyelitis. A sharp and defined margin, optimally visualized on T1-weighted images in comparison to short tau inversion recovery (STIR) images, is the most significant feature of Ewing sarcoma in differentiating from osteomyelitis.

    The purpose of this report is to evaluate the characteristic findings of tuberculosis of the breast on mammogram, sonogram, and CT and to compare the results with the imaging feature of non-tuberculous mastitis. Using mammograms and sonograms, nine cases of tuberculosis of the breast were evaluated, and for four cases, CT was used. Aspects evaluated were contour, shape and size of the lesion, homogeneity of internal content, and extension of the lesion from/to the adjacent organs. Diagnosis was based on aspiration, surgery, and pathologic findings including acid-fast bacillus (AFB) staining. Mammograms and sonograms of 19 patients with non-tuberculous mastitis of the breast were reviewed. No cases of tuberculous mastitis presented clinical evidence of acute inflammation such as fever, swelling or skin redness. Nine cases of tuberculous mastitis were seen as a distinct mass on mammogram and sonogram. Four of nine cases (44.4%) showed a relatively smooth peripheral margin on mammogram and a cold abscess form on sonogram and CT. There were other foci of tuberculosis in the chest wall, anterior mediastinum, pleural cavity or lung. Five cases demonstrated as a nodular type on US. In the non-tuberculous mastitis group, and abscess with distinct margin or direct contiguity between a breast lesion and the adjacent organ was observed neither on mammogram nor on sonogram. In an afebrile patient, relative homogeneous density with distinct margin in the breast on mammogram and a fistulous connection or direct continuity between breat abscess form with the adjacent organ on sonogram or CT is a characteristic feature of the tuberculous mastitis. The cold abscess type is a frequent subtypes of this entity, and must also be included.

    A 27-year-old female was referred to our hospital postpartum due to rapid aggravation of facial swelling. She was diagnosed with osteomyelitis on clinical, radiological, and histopathological examinations, but the possibility of malignancy was not excluded. Clinical signs and symptoms such as facial swelling and discomfort were improved with four months of antibiotics treatment. This is a case of an osteomyelitis progressed from infected extraction socket in a woman with physiological changes of pregnancy. Decreased immunological response, increased sex hormone and calcium regulatory hormones regulate the response of the bone infection. We report this case for helping the diagnosis of unusual form of osteomyelitis in pregnancy and postpartum.

    Full Text Available Background. We performed a review of published case studies of osteomyelitis associated with cat-scratch disease to consolidate existing information on clinical presentation, diagnostic tools, therapy, and outcome, as well as presenting a case of disseminated cat-scratch disease in a 12-year-old female with skull osteomyelitis and spleen involvement. Methods. A search for articles indexed in PubMed, Embase, and Google Scholar was performed with the search terms “Bartonella,” “bone,” “osteomyelitis,” “osteolytic,” and “cat-scratch disease” limited to the immunocompetent pediatric population and articles in English. Results. 51 cases were identified. The average age was 7.8 years with equal sex distribution. Fever (84.3%, often with a prolonged course (64.7%, and osteoarticular pain (88.2% were the most common clinical findings. Lymphadenopathy was present in 64.7% of patients. Vertebral body was mainly involved (51.9%. MRI (50% and bone scintigraphy (48.1% were favored to confirm osteomyelitis, while serology was the preferred microbiological diagnostic. Various antibiotics were prescribed in combined or sequential regimens, with median duration of therapy of 23 days. About 12.5% of patients did not receive any treatment. Most patients had excellent prognosis; in particular, all patients not receiving any therapy showed complete recovery and no recurrence of symptoms. Conclusions. Bartonella henselae should be considered in differential diagnosis of localized lymphadentitis. Osteoarticular pain or limitation during cat-scratch disease in children should always be investigated for bone spreading. Owing to good prognosis, invasive procedures to obtain the bone material should be avoided. Serology is the gold standard diagnostic tool and MRI is the best radiographic technique to define bone and surrounding tissue involvement. Treatment represents a never-ending dilemma: surgical intervention or use of antibiotics is still

    Although sickle-cell anemia (SCA) is common in black Americans, Sub-Saharan Africa and in the Mediterranean area, the disease is rare in the temperate climate zone. The manifestations of the disease are related mainly to the production of abnormal hemoglobin that leads to organ ischemia and increased susceptibility to infection caused by functional asplenia. The authors present CT findings in a 39-year-old black woman diagnosed due to abdominal pain, lymphadenopathy and fever. CT of the thorax and abdomen demonstrated changes in the liver, spleen, and skeletal system suggestive of SCA complicated with spondylodiscitis in the thoracic spine. Hepatomegaly and small calcified spleen are typical findings in older homozygotic patients with SCA. The lesions in the skeleton may be related either to intramedullary hematopoiesis or osteonecrosis and osteomyelitis. In the latter case, diffuse osteosclerosis and H-shaped vertebrae are most typical. Tuberculous spondylodiscitis is characterized by the location in the thoracic region, preferential involvement of anterior elements, relative sparing of intervertebral discs, and cold abscesses

    Early diagnosis and treatment of osteomyelitis provide good prognosis and prevent severe complications. Therefore, it is important to early diagnose and treat before the bony changes are observed in conventional radiograms. Authors experienced three cases of early osteomyelitis, and scintigrams were useful to differentiate them from other diseases. The purpose of this report was to aid in the early diagnosis and treatment of osteomyelitis occurred in the jaws. The characteristic features were as follows: 1. In clinical examination, the patients complained mild pain and localized swelling in the jaws. 2. In radiographic findings, the conventional radiograms showed relatively mild bony change in the jaws. 3. The more severe periosteal reactions were observed in radiograms in children than in adult patient. 4. It showed marked increased uptake of radioisotopes in all scintigrams. 5. The three phase bone scanning were helpful to differentiate osteomyelitis from soft tissue diseases.

Orofacial findings in osteopetrosis patients are unerupted, malformed, or delayed teeth and many dental caries due to vulnerable enamel and dentin and osteomyelitis. Many reports have described that maxilla is an uncommon site of occurrence for osteomyelitis due to cortical bone morphology and collateral circulation. This report aims to discuss clinical features and prosthodontic management of a patient with clinical features of adult form of osteopetrosis and osteomyelitis in both jaws. The patient has reported better masticatory and speech efficiency with removable dentures in maxillary and mandibular jaw and also self-esteem improvement and family interaction.

    Full Text Available Osteomyelitis caused by Candida glabrata is rare and its optimal treatment is unknown. Here we report a case of osteomyelitis caused by C. glabrata in the distal phalanx in a 54-year-old woman. Despite partial resection of the nail and administering a 1-month course of antibiotics for paronychia, the local swelling remained and an osteolytic lesion was found. C. glabrata osteomyelitis of the distal phalanx was later diagnosed after curettage. Thereafter, the patient was treated with antifungal agents for 3 months. The infection eventually resolved, and radiological healing of the osteolytic lesion was achieved. Antifungal susceptibility testing should be performed in the case of osteomyelitis caused by nonalbicans Candida species, due to their resistance to fluconazole.

    We experienced a case of osteomyelitis of mandibular bone in Kimura's disease. The patient received radiation therapy to head and neck area against the same disease. Bone tissue which received radiation therapy had developed malnutrition as side effect of radiation, and osteomyelitis was induced by infection from the teeth. Even in the benign soft tissue disease like Kimura's disease, especially after radiation therapy, pathologic fracture of bone may happen due to bone damage caused by radiation. (author).

    2001-01-01

    Full Text Available Erysipelothrix rhusiopathiae is known to cause infections in humans following exposure to decaying organic matter or animals colonized with the organism, such as swine and fish. Invasive infections with this organism are unusual and are manifested primarily as infective endocarditis. The present report is believed to be the first to report a case of E rhusiopathiae endocarditis and presumptive osteomyelitis. E rhusiopathiae appears to have intrinsic resistance to vancomycin. Because vancomycin is often used empirically for the treatment of endocarditis, rapid differentiation of E rhusiopathiae> from other Gram-positive organisms is critical. In patients with endocarditis caused by a Gram-positive bacillus and epidemiological risk factors for E rhusiopathiae exposure, empirical treatment with vancomycin should be reconsidered.

    Infection in the marrow of the temporal, occipital, and sphenoid bones is an uncommon, but increasing occurrence. It is usually secondary to infections beginning in the external auditory canal and is caused almost uniformly by the gram negative Pseudomonas aeruginosa bacteria. Technetium and gallium scintigraphy help in the early detection of such infections while CT scans demonstrate dissolution of bone in well-developed cases. Headache is the predominant symptom. Dysphagia, hoarseness, and aspiration herald the inevitable march of cranial nerves. We have diagnosed and treated 17 cases of osteomyelitis of the skull base. Although the total mortality rate is 53%, it is now a curable disease. Six of our last 8 patients remain alive, although 1 is still under treatment. Treatment is medical and requires the long-term concomitant intravenous administration of an aminoglycoside and a broad spectrum semisynthetic penicillin effective against the causative organism

    Full Text Available Tuberculous mastitis is a rare clinical entity and usually affects women from the Indian sub-continent and Africa. It often mimics breast carcinoma and pyogenic breast abscess clinically and radiologically, may both co-exist. Routine laboratory investigations are not helpful in its diagnosis. Fine needle aspiration cytology (FNAC / biopsy are essential for diagnosis and tuberculosis culture when positive may be very useful to guide antimicrobial therapy. Antitubercular drugs in combination with aspiration or surgical drainage are usually associated with an excellent outcome.

    The locations of cerebral infarctions were studied in 14 patients with tuberculous meningitis (TBM) and 173 patients with noninflammatory ischemic stroke (IS). In patients with TBM, 75% of infarctions occurred in the 'TB zone' supplied by medial striate and thalamoperforating arteries; only 11% occurred in the 'IS zone' supplied by lateral striate, anterior choroidal and thalamogeniculate arteries. In patients with IS, 29% of infarctions occurred in the IS zone, 29% in the subcortical white matter, and 24% in (or involving) the cerebral cortex. Only 11% occurred in the TB zone. Bilaterally symmetrical infarctions of the TB zone were common with TBM (71%) but rare with IS (5%). (orig.)

    To evaluate findings of gray-scale and color Doppler sonography in cervical tuberculous lymphadenitis (CTA). We retrospectively reviewed sonograms of tuberculous lymph nodes in eighty one patients confirmed by ultrasound-guided cutting-needle biopsy. We evaluated number, laterality, size and shape, distribution, echogenic hilus, echogeneity, nodal border, surrounding soft tissue thickening, matting, calcification on gray-scale sonograms. On color images, we analyzed the vascularity in thirty two nodes. Multiple (79%) and unilateral (90%) lymph nodes enlargement were seen. The largest diameter was from 10 mm to 31 mm (mean:19 mm). Most commonly involving area was posterior triangle (83%), followed by involvement of internal jugular chain (49%) and supraclavicular fossa (36%). In only 5 of 81 (6%) patient, the echogenic hilum was seen. The homogeneous (83%), low echogenic lymph nodes (86%) with well defined border (82%) was characteristic findings. In 11 of 14 heterogeneous echogeneity and 9 of 15 ill defined or irregular border of lymph nodes, abscess formation was proven by aspiration. On color Doppler sonogram, avascular (28%) and hilar vascular (9%) lymph nodes were seen. Whereas little (31%) and some peripheral vascularity (13%) and mixed patterns (19%) were noted in high percentage. The characteristic sonographic findings of CTA were multiple round or oval, homogeneous, quiet lower echotic, well defined, non-matting lymph nodes at the posterior cervical triangle or internal jugular chain or supraclavicular fossa with avascular or little vascularity. In cold abscesses, an inhomogeneous echotexture with irregular or ill defined border were characteristic findings.

    Objective: To evaluate the relationship of clinical and magnetic resonance imaging (MRI) findings in patients with tuberculous meningitis (TBM), and to improve the understanding of TBM. Methods: The clinical and MRI findings in 42 patients with confirmed TBM were analyzed retrospectively. MRI examination was performed using a 1 Tesla system, including SE T 1 WI and T 2 WI. Intravenous contrast was injected in 29 patients, and follow-up scans were performed on 17 patients. Results: Of 24 patients with early TBM, MRI was abnormal in 5(21%) with slight Tl-hypointense meningeal (4) or ependymal thickening (1). MRI on 33/35 (94%) patients with late stage TBM was abnormal with T 1 hypointensity and T 2 hyperintensity including meningeal thickening (19), mild surrounding brain edema (10), nodules (11), tuberculoma (5) and abscess (2). There was significant plaque-like, nodular or rim enhancement with surrounding brain edema. Conclusion: Tuberculous meningitis has minimal clinical and MRI findings in the early phase and significant clinical and MRI findings in the late phase. The enhanced scan may help to detect the abnormality. (authors)

    We present the case of a patient with primary chronic osteomyelitis of the mandible, the radiological appearance of which is compatible with a diagnosis of chronic sclerosing osteomyelitis. The accompanying femoral and tibial periosteal reactive new bone formation and the benign clinical course suggest that this presentation may represent a form of chronic multifocal osteomyelitis.

  2. Microbiota associated with chronic osteomyelitis of the jaws

    2010-12-01

    Full Text Available Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian patients. After clinical and radiographic evaluation, samples of bone sequestra, purulent secretion, and biopsies of granulomatous tissues from twenty-two patients with chronic osteomyelitis of mandible and maxilla were cultivated and submitted for pathogen detection by using a PCR method. Each patient harbored a single lesion. Bacterial isolation was performed on fastidious anaerobe agar supplemented with hemin, menadione and horse blood for anaerobes; and on tryptic soy agar supplemented with yeast extract and horse blood for facultative bacteria and aerobes. Plates were incubated in anaerobiosis and aerobiosis, at 37ºC for 14 and 3 days, respectively. Bacteria were cultivated from twelve patient samples; and genera Actinomyces, Fusobacterium, Parvimonas, and Staphylococcus were the most frequent. By PCR, bacterial DNA was detected from sixteen patient samples. The results suggest that cases of chronic osteomyelitis of the jaws are usually mixed anaerobic infections, reinforcing the concept that osteomyelitis of the jaws are mainly related to microorganisms from the oral environment, and periapical and periodontal infections may act as predisposing factors.

  3. A Rare Case of Cranial Osteomyelitis Caused by Proteus Vulgaris

    Full Text Available Osteomyelitis of the calvarial bones can cause serious complications such as brain abscess, due to the close proximity to adjacent brain structures. Development of the purulent secretion in surgery and traumatic scalp injuries must be considered as a possibility of osteomyelitis possibility. Generally gram positive, rarely gram negative bacteria and mix agents, can be isolated in infection. Especially chronic pyogenic osteomyelitis agents can be isolated from chronic infections such as tuberculosis. In cranial osteomyelitis diagnosis, radiological diagnosis has a very important place together with the clinical diagnosis. However, infection can usually show late findings radiologically. In treatment, antibiotic treatment is absolutely essential as well as removal of the infected part of the bone. Due to antibiotic treatment lasting between 6-12 weeks, organizing the antibiotic protocols according to the results of culture-antibiograms, which were provided from purulent secretions, has the most important role in the success of surgical treatment. In Proteus sp. infections, for choice of suitable treatment, determination of the type of bacteria is important. For exact diagnosis, histopathological examination of the bone tissue must be carried out. In this report, a case with cranial osteomyelitis caused by Proteus vulgaris which is a gram negative bacteria causing anaerobic infections and classified in the Enterobacteriaceae family is presented. The patient was treated with surgery and appropriate antibiotics. Early recognition of this condition, planning the best treatment strategy and taking precautions to prevent complications, is mandatory for a better outcome.

    Objective: To evaluate the features of mediastinal tuberculous lymphadenopathy in adults on CT, especially on enhanced CT scan. Methods: Seventeen patients with adult mediastinal tuberculous lymphadenopathy proved by operation, biopsy, and (or) anti-tuberculous therapy were evaluated on chest film and CT scan, and 6 patients were performed with enhanced CT scan. Results: The chest film finding was intrathoracic mass and (or) hilar mass only in 6 patients, but CT detected 37 enlarged nodes in all patients. Most of the enlarged nodes were located in 2R and (or) 4R (59.4%). 30 nodes (81.1%) presented as low-density in the center of nodes, and there were marked enhancement at the periphery areas of the nodes after enhancement in all 6 patients (100.0%). Conclusion: CT scan, especially the enhanced CT scan, is the first method of choice to diagnose the mediastinal tuberculous lymphadenopathy in adults

    Purpose: To evaluate the ultrasonographic and CT findings of tuberculous peritonitis. Material and Methods: Ultrasonographic and CT findings of 11 patients with the ascitic type of tuberculous peritonitis were reviewed. Results: All patients had ascites, and ultrasonography (US) demonstrated fine complete and incomplete mobile septations in 10 patients. In 5 of them, the ascites had a lattice-like appearance. Diffuse regular peritoneal thickening was detected in all patients by CT and in 10 patients by US. CT demonstrated infiltration of the greater omentum in 9 patients, whereas US showed omental thickening in only 5 patients. Conclusion: Peritoneal and omental thickening detected by CT and ascites with fine, mobile septations shown by US strongly suggest the ascitic type of tuberculous peritonitis. The 2 imaging modalities should be used together for accurate diagnosis of tuberculous peritonitis. (orig.).

    Maxillary osteomyelitis is a rare condition defined as inflammation of the bone primarily caused by odontogenic bacteria, with trauma being the second leading cause. The present report documents a rare case of maxillary osteomyelitis in a 38-year-old female who was the victim of domestic violence approximately a year prior to presentation. Intraoral examination revealed a lesion appearing as exposed bony sequestrum, with significant destruction of gingiva and alveolar mucosa in the maxillary right quadrant, accompanied by significant pain, local edema, and continued purulence. Teeth numbers 11, 12, 13, 14, and 15 were mobile, not responsive to percussion, and nonvital. Treatment included antibiotic therapy for seven days followed by total enucleation of the necrotic bone tissue and extraction of the involved teeth. Microscopic findings confirmed the clinical diagnosis of chronic suppurative osteomyelitis. Six months postoperatively, the treated area presented complete healing and there was no sign of recurrence of the lesion. PMID:25610667

    Radiation therapy for the head and neck malignant tumor may often cause osteoradionecrosis of the mandible, leading to radiation osteomyelitis with a source of infection. The present study demonstrates two cases with radiation osteomyelitis of the mandible to discuss the etiology, radiological findings and preventive measure for this type of bone disease. The results indicate that, 1) A higher dose in external radiotherapy may claimed to be a potent factor to cause osteoradionecrosis and post irradiation periodontitis of the tooth associated with pain, may be preliminary symptom of leading radiation osteomyelitis, where a delayed healing of tooth extraction is an accelerating factor responsible for rapid progress of osteomyelitic changes. 2) Once infection sets in post irradiated bone, radio-osteomyelitic change is quite progressive even after various conservative measure. 3) Only radiological change in those cases is a slow formation of sequestrum time ranging from 7 to 10 months, with a gradual separation of dead bone as a large mass.

    Skull base osteomyelitis is a potentially fatal disease. We demonstrate here the utility of SPECT/CT in diagnosing this entity, which was not obvious on a planar bone scan. A 99mT c MDP bone scan with SPECT/CT was carried out on a patient with clinically suspected skull base osteomyelitis. Findings were correlated with contrast enhanced CT (CECT) and MRI. Planar images were equivocal, but SPECT/CT showed intense uptake in the body of sphenoid and petrous temporal bone as well as the atlas corresponding to irregular bone destruction on CT and MRI. These findings indicate that SPECT/CT may have an additional role beyond planar imaging in the detection of skull base osteomyelitis.

    Full Text Available Objective: To focus on the increasing incidence of breast tuberculosis, its mistaken identity with carcinoma or pyogenic abscess and its effective diagnosis on cytology. Methods: This retrospective study was carried over short period of two months. Six patients were included. air dried and wet fixed smears prepared and stained with May-Grunwwald-Giemsa and Papanicolaou respectively. Zeihl Neelson staining was also applied. Results: Age groups varied from 16 to 70 years. Six cases presented within 2 months. Most common presentation was painless lump breast. One patient presented with discharging sinus. Lumps mostly favored right breast with predominance of upper outer quadrant. All except one were found to be positive for AFB. Conclusions: Incidences of tuberculous mastitis are increasing, can mimic carcinoma or abscess and should always be kept in differential diagnosis of lump breast. FNAC is helpful and ZN staining is gold standard in diagnosing acid fast bacilli.

    An 76-year-old man with an indolent soft tissue mass on the volar aspect of the left elbow was referred to our institution with a diagnosis of a soft tissue tumor. He had a history of lung tuberculosis since the age of 30. The mass was adjacent to the biceps brachi tendon. It demonstrated homogeneous low-signal intensity on T1-weighted magnetic resonance (MR) images and heterogeneous relatively high signal intensity with scattered low and high signal intensity areas on T2-weighted MR images. An excision was performed after needle biopsy with presumptive diagnosis of bicipitoradial bursitis. The histological specimen revealed an epithelioid cell granuloma with central necrosis. While the occurrence of tuberculous bicipitoradial bursitis has never been reported, this case demonstrates that it can be considered to be among the causes of a cystic lesion around the elbow joint.

The patient was a white 72-year-old man with pulmonary tuberculosis and a former smoker with hypertension, chronic renal failure, and dyslipidemia. A computed tomographic scan of the abdomen and pelvis revealed a left paravertebral cavity with fluid content and involvement of vertebrae L2–L4. After a surgical repair attempt, the patient was treated with the implant of a bifurcated endoprosthesis. Because it is unlikely that any center has extensive experience in the management of this rare manifestation of the disease, we reviewed the literature for similar cases.

    We report a rare case of a tuberculous mycotic aortoiliac pseudoaneurysm treated with an endovascular procedure and follow-up of 36 months. The patient was a white 72-year-old man with pulmonary tuberculosis and a former smoker with hypertension, chronic renal failure, and dyslipidemia. A computed tomographic scan of the abdomen and pelvis revealed a left paravertebral cavity with fluid content and involvement of vertebrae L2-L4. After a surgical repair attempt, the patient was treated with the implant of a bifurcated endoprosthesis. Because it is unlikely that any center has extensive experience in the management of this rare manifestation of the disease, we reviewed the literature for similar cases.

    Full Text Available Chronic back pain is a common presenting complaint that is frequently encountered by clinicians. The challenge for clinicians is identifying the relatively few patients with a significant probability of a more serious problem that requires further evaluation. Such individuals require further evaluation for possible occult malignancy, infection, or fracture. We present a case of a 50-year-old male with a past medical history of chronic back pain and IV drug abuse who presented with acute back pain and in whom a diagnosis of vertebral osteomyelitis was missed during multiple visits to the emergency room.

    Over the last decade, the role of nuclear medicine studies in the diagnosis of acute osteomyelitis has been discussed in depth in the literature. Yet, the respective roles played in this setting by each of the commonly used radionuclide studies often are confusing. In an attempt to develop a cogent diagnostic strategy, we reviewed the literature published within the last 12 years pertaining to the use of radiophosphate bone scintigraphy as well as gallium and indium WBC imaging in the diagnosis of this condition. Based on our findings, we propose an alternative approach to the evaluation of a patient with suspected acute osteomyelitis. 63 references

    One of the most devastating foot and/or ankle complications in the diabetic population with peripheral neuropathy is the presence of Charcot neuroarthropathy (CN). In recent years, diabetic limb salvage has been attempted more frequently as opposed to major lower extremity amputation for CN of the foot and ankle with ulceration and/or deep infection. Treatment strategies for osteomyelitis in the diabetic population have evolved. This article reviews some of the most common surgical strategies recommended for the diabetic patient with CN of the foot and/or ankle and concomitant osteomyelitis. Copyright © 2014 Elsevier Inc.

    Diabetic Charcot neuroarthropathy (DCN) poses a great challenge to diagnose in the early stages and when plain radiographs do not depict any initial signs of osseous fragmentation or dislocation in a setting of a high clinical index of suspicion. Medical imaging, including magnetic resonance imaging, computed tomography, and advanced bone scintigraphy, has its own unique clinical indications when treating the DCN with or without concomitant osteomyelitis. This article reviews different clinical case scenarios for choosing the most accurate medical imaging in differentiating DCN from osteomyelitis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Aim: To present the magnetic resonance imaging (MRI) findings of 10 patients with histopathologically proven tuberculous spondylitis (TS) presenting as vertebra plana (VP) on radiographs. Material and methods: Radiographs of 451 adult TS patients were reviewed. In this consecutive series, there were 11 patients who presented as VP. MRI of 10 of these patients was available for review. Results: VP-like collapse of a single vertebral body of the dorsal spine with preserved endplates and disc was seen in all cases. Epidural, pre- and para-vertebral soft tissue was found in all patients. Epidural soft tissue presenting on sagittal images as a convexity of the posterior longitudinal ligament was also found in all the signal of which was different from the involved vertebra on axial images. All patients showed posterior element involvement, which was characterized by preserved cortical outline without expansion. Conclusion: TS presenting with VP-like collapse of the bone is rare, accounting for 2.4% of the cases in the present series. MRI may show a collapsed vertebra with preserved endplates and disc. MRI findings that are suggestive of TS include: (1) signal intensity of the epidural soft-tissue mass on axial images, which is different from the vertebral body; (2) presence of a thin, T2-weighted hypointense capsule of the para-vertebral soft tissue; (3) posterior element involvement characterized by intact hypointense cortical outline without expansion; and (4) involvement of the costovertebral joint.

    Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed tomographic angiography and magnetic resonance angiography are constantly improving and are playing an increasingly important role in diagnosing vertebral artery pathology in clinical practice. This paper reviews the current state of vertebral artery imaging from an evidence-based perspective. Normal anatomy, normal variants and a number of pathological entities such as vertebral atherosclerosis, arterial dissection, arteriovenous fistula, subclavian steal syndrome and vertebrobasilar dolichoectasia are discussed.

    We report a case of anterior chest skin ulcer with rib and sternum osteomyelitis following radiation therapy for post operative mammary carcinoma. Operation was performed six times including debridement with sternum and rib resection reconstruction and skin grafting. It took about one and a half years after first operation to heal the ulcer with osteomyelitis. Principle of treatment for radiation ulcer accompanied by osteomyelitis is complete resection of the damaged lesion. However, it is difficult to evaluate the exact area of the damaged lesion. Therefore it is not rare to repeat its recurrence and have trouble with its treatment. In this case, it was considered that the resected area was insufficient on the initial operation. In order to treat for radiation ulcers accompanied by osteomyelitis, enough resection of the damaged lesion in the initial operation is necessary. Ultimately, in our case, the resection of all sternum, part of the right second to fifth rib and part of left second to seventh rib was necessary. It is generally said that reconstructing bone structure is required in the case of wide defect of chest wall. Though, we did not perform reconstruction of the bone structures, there is no problem in the condition of respiratory system. The surrounding soft tissues changed to hard enough to avoid paradoxical breathing. (author)

    Lumbar vertebral body and disk infection, presenting as low back pain, is a relatively uncommon disease but is seen more often in drug addicts. Radiographs show typical changes of infection of the lumbar vertebrae and adjacent disc. Under local anesthesia a fine needle is placed, saline injected, and aspirated. The entire needle-syringe unit is submitted to the bacteriology department. Pseudomonas infection is usually found. This method of diagnosis is simple, cost effective, well accepted by the patients, and can be done on outpatients. (orig.)

    OBJECTIVE The purpose of this study was to determine whether clinical and imaging features can distinguish osteomyelitis from Ewing sarcoma (EWS) and to assess the accuracy of percutaneous biopsy versus open biopsy in the diagnosis of these diseases. MATERIALS AND METHODS Three radiologists reviewed the radiographs and MRI examinations of 32 subjects with osteomyelitis and 31 subjects with EWS to determine the presence of 36 imaging parameters. Information on demographic characteristics, history, physical examination findings, laboratory findings, biopsy type, and biopsy results were recorded. Individual imaging and clinical parameters and combinations of these parameters were tested for correlation with findings from histologic analysis. The diagnostic accuracy of biopsy was also determined. RESULTS On radiography, the presence of joint or metaphyseal involvement, a wide transition zone, a Codman triangle, a periosteal reaction, or a soft-tissue mass, when tested individually, was more likely to be noted in subjects with EWS (p ≤ 0.05) than in subjects with osteomyelitis. On MRI, permeative cortical involvement and soft-tissue mass were more likely in subjects with EWS (p ≤ 0.02), whereas a serpiginous tract was more likely to be seen in subjects with osteomyelitis (p = 0.04). African Americans were more likely to have osteomyelitis than EWS (p = 0). According to the results of multiple regression analysis, only ethnicity and soft-tissue mass remained statistically significant (p ≤ 0.01). The findings from 100% of open biopsies (18/18) and 58% of percutaneous biopsies (7/12) resulted in the diagnosis of osteomyelitis, whereas the findings from 88% of open biopsies (22/25) and 50% of percutaneous biopsies (3/6) resulted in a diagnosis of EWS. CONCLUSION Several imaging features are significantly associated with either EWS or osteomyelitis, but many features are associated with both diseases. Other than ethnicity, no clinical feature improved diagnostic

    Orthopaedic devices are the most common surgical devices associated with implant-related infections and Staphylococcus aureus (S. aureus) is the most common causative pathogen in chronic bone infections (osteomyelitis). Treatment of these chronic bone infections often involves combinations of antibiotics given systemically and locally to the affected site via a biomaterial spacer. The gold standard biomaterial for local antibiotic delivery against osteomyelitis, poly(methyl methacrylate) (PMMA) bone cement, bears many limitations. Such shortcomings include limited antibiotic release, incompatibility with many antimicrobial agents, and the need for follow-up surgeries to remove the non-biodegradable cement before surgical reconstruction of the lost bone. Therefore, extensive research pursuits are targeting alternative, biodegradable materials to replace PMMA in osteomyelitis applications. Herein, we provide an overview of the primary clinical treatment strategies and emerging biodegradable materials that may be employed for management of implant-related osteomyelitis. We performed a systematic review of experimental biomaterials systems that have been evaluated for treating established S. aureus osteomyelitis in an animal model. Many experimental biomaterials were not decisively more efficacious for infection management than PMMA when delivering the same antibiotic. However, alternative biomaterials have reduced the number of follow-up surgeries, enhanced the antimicrobial efficacy by delivering agents that are incompatible with PMMA, and regenerated bone in an infected defect. Understanding the advantages, limitations, and potential for clinical translation of each biomaterial, along with the conditions under which it was evaluated (e.g. animal model), is critical for surgeons and researchers to navigate the plethora of options for local antibiotic delivery.

    2014-09-01

    Full Text Available Making an accurate diagnosis of tuberculous cervical lymphadenitis (TCL has been a problem to clinicians because it is a versatile masquerader and is often confused with lymphomas or cervical metastases. Ultrasound (US has advantages over other examination modalities in that it is noninvasive, inexpensive, time-saving, and able to guide procedures such as fine-needle aspiration and core-needle biopsy. It is increasingly being recognized as a primary tool for the evaluation of cervical lymph nodes. In this article, we present six cases with microscopically and/or pathologically confirmed TCL and illustrate the US features. A literature review was also conducted. The key US features of TCL include hypoechogenecity, strong internal echoes, echogenic thin layers, nodal matting, soft tissue changes, and displaced hilar vascularity. US is a reliable and effective tool in assessing cervical lymphadenopathies. When TCL is suspected under US, US-guided procedures such as fine-needle aspiration or core-needle biopsy can be conducted concomitantly to obtain the microscopic or pathological proof.

    Full Text Available Tuberculosis (TB is still endemic in many developed countries. Involvement of the hand and wrist at presentation is extremely rare, and the diagnosis is often missed. A 57 years old male presented with swelling over the left wrist since 3 years Three swellings over dorsal aspect of the left wrist Soft in consistency Non tender Non compressible Mobile at right angles to the plane of the wrist joint. ESR: 45 mm in 1 hr and rest blood investigations were normal. Ultrsonography showed giant cell tumor of Extensor Digitorum sheath. X-ray: soft tissue swelling and MRI was suggestive of extensor tendon sheath extraskeletal synovial Koch’s, or giant cell tumor of tendon sheath. Excision of swelling was planned and intraoperatively, rice bodies were seen inside it. Histopathological examination showed caseous necrosis with granuloma formation. Patient was put on DOT1 therapy. Tuberculous tenosynovitis was first described by Acrel in 1777. Rice bodies occurring in joints affected by tuberculosis were first described in 1895 by Reise. Rice bodies will be diagnosed on plain radiographs when mineralization occurs. More than 50% of cases recur within 1 year of treatment. The currently recommended 6-month course is often adequate with extensive curettage lavage and synovectomy should be performed. Surgery is essential, but the extent of surgical debridement is still debatable. The surgeon has to be aware of the significance of loose bodies when performing routine excision of innocuous looking wrist ganglia.

    Objective: To determine the frequencies and percentages of various clinicoradiologic variables of tuberculosis meningitis (TBM) with reference to British Medical Research Council (BMRC) staging of the disease. Study Design: A case series. Place and Duration of Study: Department of Neurology, Jinnah Postgraduate Medical Centre, Karachi, from October 2010 to September 2011. Methodology: The study included 93 adult patients with the diagnosis of tuberculous meningitis (TBM) at the study place. Patients were divided in three groups according to British Medical Research Council (BMRC) staging of TBM. Different clinical and radiological findings were analyzed at different stages of the disease. Data was analyzed using SPSS (Statistical Package of Social Sciences) version 11.0. Results: A majority of patients were found to be in stage-II disease at the time of admission. History of illness at the time of admission was more than 2 weeks in 50% of stage-I patients but around 80% in stage-II and stage-III patients. Neck stiffness was the most commonly reported finding in all stages. Cranial nerve palsies were higher in stage-III (75%) than in stage-II (43%) and in stage-I (24%) patients. Hydrocephalus and basal enhancement was the most frequently reported radiographic abnormalities. Conclusion: Duration of illness and cranial nerve palsies are important variables in the diagnosis of TBM stages and if TBM is suspected, empiric treatment should be started immediately without bacteriologic proof to prevent morbidity and mortality.

    2011-01-01

    Full Text Available Tuberculous meningitis (TBM is the most common form of central nervous system tuberculosis (TB and has very high morbidity and mortality. TBM is typically a subacute disease with symptoms that may persist for weeks before diagnosis. Characteristic cerebrospinal fluid (CSF findings of TBM include a lymphocytic-predominant pleiocytosis, elevated protein, and low glucose. CSF acid-fast smear and culture have relatively low sensitivity but yield is increased with multiple, large volume samples. Nucleic acid amplification of the CSF by PCR is highly specific but suboptimal sensitivity precludes ruling out TBM with a negative test. Treatment for TBM should be initiated as soon as clinical suspicion is supported by initial CSF studies. Empiric treatment should include at least four first-line drugs, preferably isoniazid, rifampin, pyrazinamide, and streptomycin or ethambutol; the role of fluoroquinolones remains to be determined. Adjunctive treatment with corticosteroids has been shown to improve mortality with TBM. In HIV-positive individuals with TBM, important treatment considerations include drug interactions, development of immune reconstitution inflammatory syndrome, unclear benefit of adjunctive corticosteroids, and higher rates of drug-resistant TB. Testing the efficacy of second-line and new anti-TB drugs in animal models of experimental TBM is needed to help determine the optimal regimen for drug-resistant TB.

    Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). To demonstrate the incidence, distribution and appearance of localized basal meningeal enhancement in children with TBM. CT scans of patients with definite (culture proven) and probable (CSF suggestive) TBM were retrospectively evaluated by two observers. Localized basal enhancement was documented as involving: unilateral cistern of the lateral fossa (CLF), unilateral sylvian fissure, unilateral CLF and sylvian fissure in combination, unilateral CLF and sylvian fissure with ipsi- or contralateral ambient cistern and isolated quadrigeminal plate cistern. The study included 130 patients with TBM (aged 2 months to 13 years 9 months). Focal basal enhancement was seen in 11 patients (8.5%). The sylvian fissure was involved most commonly, followed by the lateral fossa cistern. The ambient cistern was involved in three patients and the quadrigeminal plate cistern in one. Focal areas of enhancement corresponded to the areas of infarction in every patient. Focal basal meningeal enhancement is common (8.5%) in paediatric TBM. This must be kept in mind when evaluating CT scans in children presenting with focal neurological findings, seizures or meningism in communities where TBM is endemic. (orig.)

    To study the factors related to the development of residual pleural thickening in pleural tuberculosis. We studied 39 patients with tuberculous pleural effusion. A chest X-ray was taken of each patient at the end of treatment. The patients' medical histories, pleural fluid findings and diagnostic chest films were evaluated. Residual pleural thickening was defined as thickening that was visibly greater than 2 mm in the lower side portion of the chest film. Residual pleural thickening developed in 26% of patients and was found mainly in men (RR = 3.86). In no patients with Löwenstein-Jensen cultures positive for Mycobacterium tuberculosis did pleural complications develop. Residual pleural thickening is a common complication of tuberculous pleural effusion. Residual pleural thickening in tuberculous pleurisy occurs more often in men and older patients, and in cases in which pleural liquid culture is negative for M. tuberculosis.

    We report recent MRI findings in patients with tuberculous tenosynovitis of the wrist. Marked synovial thickening around the flexor tendons and fluid in the tendon sheath were clearly shown on MRI. Post-contrast study was useful in distinguishing the thick tenosynovium from the surrounding structures and fluid in the tendon sheath. The well-enhanced tenosynovium was also seen in the carpal tunnel in all cases. On the basis of these findings, we could easily distinguish tenosynovitis from other soft-tissue-mass lesions, such as tumors or infected ganglia. Tuberculous tenosynovitis is often not diagnosed early, and its differentiation from soft tissue tumors may be clinically difficult. MRI, particularly post-contrast study, is useful for early diagnosis of, and planning treatment for, tuberculous tenosynovitis. (orig.). With 3 figs.

    Objective: To determine the presence of AQP-10 in the ileum of patients suffering from intestinal tuberculosis. Study Design: A cross-sectional analytical study. Place and Duration of Study: Department of Anatomy, University of Health Sciences, Lahore, in year 2010. Methodology: Thirty seven paraffin embedded blocks of either surgically resected specimens or ileal biopsies with diagnosis of intestinal tuberculosis were selected from records of the histopathology departments of local hospitals. These cases were subdivided into two groups: A-1 (with tuberculous granulomatous lesions with or without epithelium) and A-2 (without tuberculous lesion lying adjacent to the lesions and having an intact epithelium). Specimens of small intestine with malignancy, Crohn's disease, inflammatory bowel disease, irritable bowel syndrome and diarrhoeal diseases caused by Rota virus, adenovirus, Salmonella, Shigella and Escherichia coli were excluded. The variables studied were the presence/absence and location of AQP-10. The most common clinical symptoms found in tuberculous patients were abdominal pain followed by diarrhoea. A significant association was found between AQP-10 and site of granulomas and caseation necrosis (p=0.002 and p=0.006 respectively). Absence of AQP-10 was observed in tuberculous ileum at the site of lesion with ulceration. A strong positive staining of AQP-10 was found in the intact epithelium at sites adjacent to the tuberculous lesion indicating its localization near the epithelial lining of ileum. Conclusion: AQP-10 was present only on the epithelial cells occurring at the luminal side of the villi and was absent in tuberculous ileum where epithelium was absent. (author)

    Tuberculosis [TB] of the appendicular skeleton is an uncommon infection caused by the tuberculous bacilli and constitutes only 1-3% of all tuberculosis infections. MR imaging features of tuberculous arthritis include bone marrow oedema, cortical erosions, synovitis, joint effusion, tenosynovitis, soft tissue collections, and myositis. These imaging features are at times non-specific, but in the correct clinical context help in diagnosis of tuberculosis. We present the various pathological manifestations of TB arthritis involving the different joints of appendicular skeleton and discuss their MR imaging appearances.

Patients with this condition usually present with a protracted illness, jaundice, and weight loss, which may be confused with malignancies. We are reporting unusual case of isolated enlarged tuberculous lymph node compressing the common bile duct in the retropancreatic region and causing obstructive jaundice in an immunocompetent patient which to the best of our knowledge is the first case of isolated retropancreatic tuberculous lymphadenitis in Saudi Arabia.

    Tuberculosis [TB] of the appendicular skeleton is an uncommon infection caused by the tuberculous bacilli and constitutes only 1-3% of all tuberculosis infections. MR imaging features of tuberculous arthritis include bone marrow oedema, cortical erosions, synovitis, joint effusion, tenosynovitis, soft tissue collections, and myositis. These imaging features are at times non-specific, but in the correct clinical context help in diagnosis of tuberculosis. We present the various pathological manifestations of TB arthritis involving the different joints of appendicular skeleton and discuss their MR imaging appearances

    Full Text Available Osteomyelitis is defined as an infection of the bone, bone marrow, and the surrounding soft tissues. Most cases of acute hematogenous osteomyelitis in children are caused by Gram-positive bacteria, principally Staphylococcus aureus. We present a case where a 5-month-old male had an acute onset of decreased movement of his left leg and increased irritability and was subsequently diagnosed with rickets and hematogenous osteomyelitis with bacteremia. The case explores a possible association between hematogenous osteomyelitis and rickets.

    Malignant transformation is a rare and late complication of untreated chronic osteomyelitis. Known radiographic findings of the malignant transformation of chronic osteomyelitis are osteolytic or mixed sclerotic and osteolytic lesions with or without soft tissue mass. But its magnetic resonance (MR) imaging findings are rarely described in the literature. We experienced a case of an 82-year-old man diagnosed with squamous cell carcinoma arising from long standing chronic osteomyelitis of the tibia. Our case indicates that radiologists should consider the possibility of malignant transformation in patients with untreated chronic osteomyelitis, with enhancing soft tissue mass invading and extending through underlying bone cortex and medulla on MR imaging.

  12. Non-Bacterial Chronic Recurrent Osteomyelitis of the Clavicle

    Full Text Available This report details the case of a 12-year-old girl with a painful, progressive swelling of the medial portion of the clavicle with no history of trauma or other constitutional symptoms. All laboratory investigations were normal except for an elevated erythrocyte sedimentation rate (ESR. Initial plain radiographs showed a destructive lesion with magnetic resonance imaging showing features of malignancy. Biopsies revealed osteomyelitis, but with negative bacterial cultures and no evidence of malignancy. Treatment with antibiotics did not result in a favourable response. Over time, the swelling increased in size with episodic exacerbations of pain. Follow-up radiographs showed sclerosis and hyperostosis. After five years, this was recognized as non-bacterial chronic recurrent osteomyelitis of the clavicle.

    The findings of technetium 99m MDP and gallium 67 citrate scintigraphy are described in the first four days following experimental acute osteomyelitis of the tibia of rabbits. On the day of inoculation, defects in activity are observed in both the perfusion and bone phases of technetium scintigraphy. Similar defects are achieved by saline injection. On subsequent days technetium scintigraphy reveals an increased activity in the perfusion stage but a persisting defect of activity in the bone phase. Gallium activity is increased throughout the period of the study in inoculated animals but not in those injected with saline. It is concluded that 99 Tcsup(m) MDP, in its perfusion phase, and 67 Ga citrate are highly sensitive indicators of bone inflammation and that early osteomyelitis is characterized by increased activity with these agents together with a technetium bone scan defect.

    2013-05-01

    Chronic suppurative osteomyelitis (CSO) of the maxillofacial region is primarily caused by infections of odontogenic microorganisms. It may also arise as a complication of dental extractions, maxillofacial trauma, inadequate treatment of a fracture and irradiation to the mandible. This condition is characterized by areas of devitalized bone (sequestra) which serves as a nidus for recurrent episodes of infection. This case report describes a case of CSO in an untreated right subcondylar fracture of the mandible which was successfully treated with a combination of antibiotic therapy and surgical debridement in an 8-year-old boy.

    Classic theories of vertebrate head segmentation clearly exemplify the idealistic nature of comparative embryology prior to the 20th century. Comparative embryology aimed at recognizing the basic, primary structure that is shared by all vertebrates, either as an archetype or an ancestral developmental pattern. Modern evolutionary developmental (Evo-Devo) studies are also based on comparison, and therefore have a tendency to reduce complex embryonic anatomy into overly simplified patterns. Her...

  16. Tuberculous pleural effusions: advances and controversies

    Allwood, Brian W.; Diacon, Andreas H.; Koegelenberg, Coenraad F. N.

    2015-01-01

    On a global scale, tuberculosis (TB) remains one of the most frequent causes of pleural effusions. Our understanding of the pathogenesis of the disease has evolved and what was once thought to be an effusion as a result of a pure delayed hypersensitivity reaction is now believed to be the consequence of direct infection of the pleural space with a cascade of events including an immunological response. Pulmonary involvement is more common than previously believed and induced sputum, which is grossly underutilised, can be diagnostic in approximately 50%. The gold standard for the diagnosis of tuberculous pleuritis remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli (AFB). In high burden settings, however, the diagnosis is frequently inferred in patients who present with a lymphocytic predominant exudate and a high adenosine deaminase (ADA) level, which is a valuable adjunct in the diagnostic evaluation. ADA is generally readily accessible, and together with lymphocyte predominance justifies treatment initiation in patients with a high pre-test probability. Still, false-negative and false-positive results remain an issue. When adding closed pleural biopsy to ADA and lymphocyte count, diagnostic accuracy approaches that of thoracoscopy. The role of other biomarkers is less well described. Early pleural drainage may have a role in selected cases, but more research is required to validate its use and to define the subpopulation that may benefit from such interventions. PMID:26150911

    There is no consensus regarding the diagnostic and therapeutic strategy for pubic osteomyelitis secondary to pelvic pressure sores. Diagnosis is often difficult and bone biopsies with microbiological and anatomical-pathological examination remain the gold standard. The rate of cicatrisation of pressure sores is low. Cleansing and negative pressure treatment are key elements of the treatment. Optimising the care management with medical-surgical collaboration is being studied in the Ostear protocol.

    1988-01-01

    To Appreciate the value of bone scintigraphy in determination of the bony infection, we performed three phase bone scintigraphy in 34 cases of osteomyelitis of extremities prospectively. They were clinically inactive in 11 and active in 23 cases. We confirmed the active osteomyelitis by operation or aspiration within one week after scintigraphy. Perfusion, blood pool and delayed images were analyzed respectively and compared with the plain roentgenograms. All 23 active lesions showed diffusely increased perfusion in affected limbs. The areas of the increased activities on blood pool images were larger than or similar to those on delayed images in 17 cases (73.9%) with active osteomyelitis and smaller in 6 cases (26.1%). 5 of the latter 6 cases showed definite soft tissue activities on blood pool images. In inactive cases bone scintigrams were completely normal in 4 cases. Two of those were normal on plain films and remaining two showed mild focal bony sclerosis. Among 7 inactive lesions, perfusion was normal in 2 cases, diffusely increased in 4 cases and diffusely decreased in 1 case. 6 of these 7 cases showed increased activities both on blood pool and delayed images and the areas of increased activities on blood pool images didn't exceed those on delayed images. Bony sclerosis was noted on plain films in those 7 inactive lesions and the extent of the sclerosis correlated well to delayed images. Large blood pool activity was characteristics of active osteomyelitis. Normal three phase bone scintigram may indicate the time to terminate the treatment, but increased activity on perfusion and blood pool scans is not absolute indication of active lesion if the extent of the lesion on the blood pool image is smaller than that on delayed image and if no definite soft tissue activity is noted on perfusion and blood pool images in clinically inactive patient.

    Conspicuous vertebral column abnormalities in humpback dolphins (genus Sousa) were documented for the first time during 3 photo-identification field studies of small populations in Taiwan, Senegal and Angola. Seven Taiwanese humpback dolphins S. chinensis taiwanensis with vertebral column anomalies (lordosis, kyphosis or scoliosis) were identified, along with 2 possible cases of vertebral osteomyelitis. There was evidence from several individuals photographed over consecutive years that the anomalies became more pronounced with age. Three Atlantic humpback dolphins S. teuszii were observed with axial deviations of the vertebral column (lordosis and kyphosis). Another possible case was identified in a calf, and 2 further animals were photographed with dorsal indents potentially indicative of anomalies. Vertebral column anomalies of humpback dolphins were predominantly evident in the lumbo-caudal region, but one Atlantic humpback dolphin had an anomaly in the cervico-thoracic region. Lordosis and kyphosis occurred simultaneously in several individuals. Apart from the described anomalies, all dolphins appeared in good health and were not obviously underweight or noticeably compromised in swim speed. This study presents the first descriptions of vertebral column anomalies in the genus Sousa. The causative factors for the anomalies were unknown in every case and are potentially diverse. Whether these anomalies result in reduced fitness of individuals or populations merits attention, as both the Taiwanese and Atlantic humpback dolphin are species of high conservation concern.

    Osteomyelitis, which is characterized by progressive inflammatory destruction and new opposition of bone, is still a difficult infection to treat. The clinical diagnosis in late stages is achieved easily, but an early diagnosis is more challenging. Staphylococcus aureus is a common agent found in osteomyelitis and bone prostheses infection. Diagnosis by scintigraphy has advantages because it is a non-invasive procedure and is able to perform an early diagnosis even before anatomic changes. Thus, nuclear medicine could contribute to an accurate diagnosis since specific radiopharmaceuticals were developed. In this study, aptamers selected to Staphylococcus aureus were labeled with {sup 99m}Tc and used for bacteria identification in an osteomyelitis experimental model. The aptamers selected to S. aureus were directly labelled with {sup 99m}Tc and were evaluated by biodistribution studies. Wistar rats with intraosseous infection in the right paw were used. A random aptamer labelled with {sup 99m}Tc was as control. Six animals were used in each group. The aptamers labeled with {sup 99m}Tc were able to identify the infection foci caused by S. aureus displaying a target/non-target ratio of 2,23 ± 0,20, after 3 h. The control group presented a target/non-target ratio 1,08 ± 0.23. The results indicated that the radiolabeled aptamers were able to identify specifically the infection foci and they should be further explored for infection diagnosis by scintigraphy. (author)

  3. An unusual osteomyelitis caused by Moraxella osloensis: A case report

    Directory of Open Access Journals (Sweden)

    Nidal J. Alkhatib

    Full Text Available Introduction: Moraxella osloensis is a gram-negative coccobacillus, that is saprophytic on skin and mucosa, and rarely causing human infections. Reported cases of human infections usually occur in immunocompromised patients. Presentation of case: We report the second case of M. osloensis-caused-osteomyelitis in literature, occurring in a young healthy man. The organism was identified by sequencing analysis of the 16S ribosomal RNA gene. Our patient was treated successfully with surgical debridement and intravenous third-generation cephalosporins. Discussion: M. osloensis has been rarely reported to cause local or invasive infections. Our case report is the second case in literature and it is different from the previously reported case in that our patient has no chronic medical problems, no history of trauma, with unique presentation and features on the MRI and intraoperative finding. Conclusion: Proper diagnosis is essential for appropriate treatment of osteomyelitis. RNA gene sequence analysis is the primary method of M. osloensis diagnosis. M. osloensis is usually susceptible to simple antibiotics. Keywords: Moraxella osloensis, Osteomyelitis, Case report

    To evaluate ultrasonographic findings of neonatal patients who confirmed and treated as hip joint septic arthritis and osteomyelitis. We retrospectively examined clinical feature and radiologic findings of 7 neonatal patients ranging from 8 to 28 days of age who were examined from January 1966 to December 1998 at nursery and were confirmed and treated on the diagnosis of septic arthritis and osteomyelitis. Clinical features of the patients were comparatively analyzed with radiologic findings including plain radiographs, ultrasonography, bone scan and MRI. We emphasized importance of ultrasonographic findings of these patients. Ultrasonography was performed first of all in all cases after the symptom onset. Other examinations were performed on the same day or a few days later after ultrasonography. Ultrasonography revealed abnormal finding in 85.7% (6/7) of all cases. Plain radiographs revealed abnormal findings in 28.6% (2/7). Bone scan revealed decreased uptake in 66.7%(2/3). MRI revealed abnormal signal intensity in 100%(3/3). Ultrasonographic findings of the patients were deep soft swelling in 85.7% (6/7) of all cases, periosteal elevation in 57.1% (4/7), synovial thickening in 42.8% (3/7), synovial effusion in 42.8%(3/7), echogenic debris or clot in 28.5% (2/7), cortical erosion in 28.5% (2/7), and subperiosteal abscess in 14.2% (1/7). Ultrasonography is a useful modality to diagnose septic arthritis and osteomyelitis in neonatal hip.

    To determine the magnetic resonance (MR) imaging findings of tuberculous arthritis, and the frequency-in such cases-with which tuberculoma occurs. MR images of 26 patients (M;F, 14;12: mean age, 46.2 years) with pathologically proven tuberculous arthritis were retrospectively reviewed. The presence of joint effusion, subchondral erosion, synovial proliferation and soft tissue abscess, and whether the inner wall of this abscess was smooth, were assessed. In particular, we determined whether a nodular lesion which showed low SI on T1WI, central low SI with peripheral hjigh SI on T2WI, and rim enhancement on contrast study, was a tuberculoma. The joints involved were those of the knee (n=7), hip (n=7), shoulder (n=4), sacroiliac region (n=3), elbow (n=3), and ankle (n=2). Joint effusion was noted in 15 cases (58%), and subchondral erosion in 24 (92%). synovial proliferation was found in 23 cases (88%), and soft tissue abscess in 24 (92%). The inner wall of this abscess was irregular in 17 cases (71%). A tuberculoma was present in intra-or extra-or extra-articular soft tissue in 18 cases (69%). The MR findings of tuberculous arthritis were subchondral erosion, synovial proliferation, and soft tissue abscess. The presence of a tuberculoma in intra-or extra-articular soft tissue, a specific finding in tuberculous arthritis, was noted in 69% of our cases.

    To determine the frequency of tuberculous cervical lymphadenopathy mimicking metastasis from papillary thyroid cancer. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from March 2005 to March 2010. Methodology: All patients above 12 years of age of either gender diagnosed on investigations as papillary thyroid cancer (PTC) were included in the study. Ultrasound and fine needle aspiration cytology (FNAC), neck of solitary thyroid nodules (STN) and cervical lymph nodes were done. Total thyroidectomy and excision biopsy of cervical lymph nodes was performed, histopathological results were recorded and patients were managed accordingly. Results: A total of 55 patients had PTC and 25 had cervical lymphadenopathy. Eighteen patients of PTC with cervical lymphadenopathy were diagnosed after investigations as cases of tuberculous cervical lymphadenopathy (TCL) initially considered as metastasis from PTC; 5 patients had metastasis from PTC. Two patients proved to be of reactive hyperplasia which initially showed tuberculous cervical lymphadenopathy on FNAC. So 80% patients of cervical lymphadenopathy with PTC were due to benign disease and 20% had metastasis in lymph node due to PTC. Conclusion: PTC with cervical lymphadenopathy due to co-existent tuberculosis is common. Metastasis from PTC in lymph nodes were less common than tuberculous lymphodenitis in this study. Tuberculosis should be considered before deciding for neck dissection in cases of PTC. (author)

    An elevated level of adenosine deaminase (ADA) in pleural liquid has been considered as a supplemental diagnostic marker for tuberculous pleurisy. However, this is complicated by false-positives and -negatives. Recently, it has been revealed that various cytokines are intimately involved in the pathognomonic physiology of tuberculosis. In this study, interleukin-8 (IL-8), tumour necrosis factor alpha (TNFalpha) and interferon gamma (IFNgamma) were compared with ADA in pleural liquid of patients with inflammatory (21 cases), malignant (28 cases) and tuberculous (21 cases) disease. The pleural ADA, IL-8, TNFalpha and IFNgamma levels in the tuberculous group were higher than in the other three groups. Analysis of receiver operating characteristic (ROC) curves, to evaluate the utility of the various parameters, demonstrates values for the area under the curve (AUC) of 0.770, 0.875, 0.892 and 0.987, respectively for IL-8, TNFalpha, ADA and IFNgamma. No false-positives were encountered with IFNgamma and only one case with a small volume of pleural liquid was a false-negative. This indicates that IFNgamma is a very reliable marker of tuberculous pleurisy.

    Interpretation: Patients with culture confirmed tuberculous pericarditis have a high bacillary burden, and this bacterial burden drives mortality. Thus proven tuberculosis pericarditis is not a paucibacillary disease. Moreover, the severe immunosuppression suggests limited inflammation. There is a need for the design of a highly bactericidal regimen for this condition.

    The purpose of this study is to evaluate the diagnostic accuracy of CT in the differential diagnosis of tuberculous and malignant pleural effusion whether or not lung lesions are present, and to investigate the CT findings used for this differential diagnosis. This study involved 30 patients with tuberculous pleural effusion (mean age, 44.6 years; M : F = 19:11) and 20 with malignant pleural effusion (mean age, 57.2 years; M: F=10:10). All 50 patients underwent enhanced CT chest scans, and the respective conditions were pathologically confirmed. Two radiologists unaware of the pathologic results and distributions of patients reviewed these scans, CT findings of pleural effusions, their diagnoses, and the degree of confidence of their diagnoses. In most cases, CT provided correct differential diagnosis between tuberculous and malignant pleural effusion. It can help determine the nature of associated lung and pleural lesions, and specific findings of the latter, and can accurately differentiate tuberculous and malignant pleural effusion.

    1988-01-01

    The efficacy of clindamycin in the treatment of experimentally induced, posttraumatic Staphylococcus aureus osteomyelitis was studied in dogs. At the end of the experiment, bacteria could not be isolated from bone marrow of 15 of 16 (93.7%) dogs treated with clindamycin, whereas bacteria could not be isolated from similar specimens obtained from 6 of 13 (46.1%) untreated dogs. None of the 16 dogs treated with clindamycin had histopathologic evidence of osteomyelitis at the end of the experiment. Five of the 13 untreated control dogs had histopathologic evidence of osteomyelitis. The recovery rate was 31% in untreated dogs, whereas 94% of dogs treated with clindamycin recovered from osteomyelitis. Clindamycin, 11 mg/kg of body weight, given orally, q 12 h, for 28 days, was efficacious in the treatment of experimentally induced, posttraumatic S aureus osteomyelitis in dogs

    1983-01-01

    Computerized tomography (CT) was performed in 19 patients with spinal cord injury (SCI) who had large pressure sores and in whom other complications were suspected. CT detected the depth, extent, and degree of undermining of the edges of the pressure sores in 19 of 27 lesions. Conventional radiography detected four cases of pelvic osteomyelitis. CT detected eight additional cases of pelvic osteomyelitis, as well as eight clinically unsuspected peripelvic and intrapelvic abscesses. Technetium-99m bone scanning was not very helpful because of localization in chronic proliferative changes of bone and widespread foci of myositis ossificans, as well as in osteomyelitis. Gallium-67 scanning detected only one of six abscesses. It was not very helpful because of confusion of abscess and osteomyelitis with intense soft tissue swelling and cellulitis, which are often associated with pressure sores in patients with chronic SCI. CT was found to be, by far, the modality of choice for detection of pelvic osteomyelitis and abscess in patients with SCI

    2007-01-01

    Full Text Available Abstract Background Hypophosphatasia (HP is characterized by a genetic defect in the tissue-nonspecific alkaline phosphatase (TNSALP gene and predominantly an autosomal recessive trait. HP patients suffer from reduced bone mineralization. Biochemically, elevated concentrations of substrates of TNSALP, including pyridoxal-5'-phosphate and inorganic pyrophosphate occur in serum, tissues and urine. The latter has been associated with chronic inflammation and hyperprostaglandinism. Case presentation We report on 2 affected children presenting with multifocal inflammatory bone lesions mimicking malignancy: A 6 years old girl with short stature had been treated with human growth hormone since 6 months. Then she started to complain about a painful swelling of her left cheek. MRI suggested a malignant bone lesion. Bone biopsy, however, revealed chronic inflammation. A bone scan showed a second rib lesion. Since biopsy was sterile, the descriptive diagnosis of chronic non-bacterial osteomyelitis (CNO was established. The diagnostic tests related to growth failure were repeated and subsequent analyses demonstrated a molecular defect in the TNSALP gene. The second girl (10 years old complained about back pain after she had fallen from her bike. X rays of her spine revealed compressions of 2 thoracic vertebrae. At first these were considered trauma related, however a bone scan did show an additional lesion in the right 4th rib. A biopsy of this rib revealed a sterile lympho- plasmocytoid osteomyelitis suggesting multifocal CNO. Further analyses did show a decreased TNSALP in leukocytes and elevated pyridoxal phosphate in plasma, suggesting a heterozygous carrier status of HP. Conclusion Chronic bone oedema in adult HP and chronic hyper-prostaglandinism in childhood HP do suggest that in some HP patients bone inflammation is present in conjunction with the metabolic defect. Sterile multifocal osteomyelitis could be demonstrated. Non-steroidal anti

    Full Text Available Chest pain is a common presenting symptom with a broad differential. Life-threatening cardiac and pulmonary etiologies of chest pain should be evaluated first. However, it is critical to perform a thorough assessment for other sources of chest pain in order to limit morbidity and mortality from less common causes. We present a rare case of a previously healthy 45 year old man who presented with focal, substernal, reproducible chest pain and Staphylococcus aureus bacteremia who was later found to have primary Staphylococcus aureus sternal osteomyelitis.

    Infections of the bone, spine and prosthetic joints are serious and complex conditions to diagnose and to treat. Structured diagnostic workup may very well improve the accuracy and speed of diagnosis, thereby improving the outcome since treatment may very well be more successful and less harmful if timely management is started. Literature shows no uniform advise on diagnosis. The EANM organized a consensus meeting with representatives from the involved disciplines in order to develop common flowcharts for the diagnosis of osteomyelitis, spondylodiscitis and prosthetic joint infections. In this report the proceedings of this consensus meeting, including the proposed flowcharts for diagnosis, are published.

    A 63-year-old man was admitted for headache and progressive drowsiness. In spite of negative results from cerebrospinal fluid (CSF) stains and cultures of tuberculosis and other bacteria, CSF findings and tuberculosis-positive sputum culture led to a tentative diagnosis of tuberculous meningitis. Symptoms and neurological test results both improved remarkably during antituberculous chemotherapy. Although the brain CT scan taken on admission showed no abnormal findings, one taken two months later revealed multiple high-density areas after enhancement with a contrast medium, suggesting multiple intracranial tuberculomas accompanied by tuberculous meningitis. The size of the multiple high-density areas gradually decreased during antituberculous chemotherapy. The CT scan can clearly locate lesions, detect complications, and evaluate the effects of treatment in patients with intracranial tuberculosis. (author)

    Ankylosing tuberculosis is an infection caused by Mycobacterium tuberculosis in one or more components of the vertebrae; it is Pott disease or tuberculous spondylitis. It might become a potential cause of morbidity, including neurological deficits and permanent deformity of the spine. Management of TB Spondylitis, in general, is chemotherapy with antituberculosis drugs (ATG), immobilization, and spine surgical interventions. A retrospective study was conducted to analyze the patients of TB Spondylitis who had undergone surgery at Haji Adam Malik hospital from June 2015 to June 2017. The most common location is thoracal (10%), lumbal (3%), and thoracolumbal junction (3%). Decompression laminectomy with fusion (18%) is the most suitable option for surgical management. The majority, pre- operation ASIA scale is D (8%), and post operation is E (8%). It means that surgical plays an important role in themanagement of tuberculous spondylitis.

    Patients with HIV can often present a diagnostic challenge and may have atypical presentations of more common diseases. This case demonstrates a HIV (+) patient with an advanced immunosuppression with tuberculosis complaining about 2 months before admission to the hospital of backache, anorexia and weight loss. On investigation she was found to have unilateral tuberculous psoas abscesses, diagnosed microbiologically and with a CT scan. Complex treatment (surgical, tuberculostatics, antiretroviral) was performed with a good effect. A review of the literature shows that this is a rare presentation of an already unusual problem, with subtle signs requiring a high index of clinical suspicion. However, with HIV-positive patients more likely to present with extrapulmonary tuberculosis, there is need for increased awareness of this diagnosis. (authors) Key words: HIV.

    We describe two cases of tuberculous otitis media studied with high-resolution computed tomography (CT). Findings included extensive soft tissue densities with fluid levels in the tympanic cavity, the antrum, the mastoid and petrous air cells. Multifocal bony erosions and reactive bone sclerosis were seen as well. CT proved valuable for planning therapy by accurately displaying the involvement of the various structures of the middle and inner ear. However, the specific nature of the disease could only be presumed. (orig.)

    Objective: To analyze the CT findings of tuberculous lymphadenitis in parotid gland, so as to improve the diagnostic accuracy of tuberculosis of parotid gland. Methods: Nine cases with tuberculous lymphadenitis in parotid gland confirmed by surgical pathology and acid-fast bacilli after preoperative spiral CT plain scan and two phases dynamic enhancement scan were retrospectively analyzed. Imaging findings of CT were reviewed and compared with surgical pathology. Results: Seven of the 9 cases of tuberculosis of the parotid gland occurred in the left side, and 2 in the right side, and superficial lobe involvement occurred in 8 cases and deep lobe in 1 case. The lesion was classified as tumour type (8 cases) and infiltration type (1 case). In turnout type, the number of lesion was from 1 to 4, and the size was from 2.7 to 5.3 cm in diameter. One case of infiltration type measured 3.4 cm in diameter. On CT plain scan, the lesions showed homogeneous slight high-density with regular edge in 5 cases and irregular low-density in 4 cases, and 2 of them with partly blurred edge. On CT enhanced scan, uniform moderate enhancement was seen in 3 cases, circular enhancement in 4 cases, inhomogeneous enhancement in 1 case, and lace-like enhancement in 1 case. Local infiltration occurred in 6 cases. Lymphadenovarix in the same side of lesion occurred in 2 cases. Conclusion: CT findings of tuberculous lymphadenitis in parotid gland present diversification, which correlate well with pathological changes. Understanding of characteristic CT findings of tuberculous lymphadenitis in parotid gland is helpful for differential diagnosis, but final diagnosis still depends on pathology and acid-fast bacilli.

    Tuberculous radiculomyelitis (arachnoiditis) remains one of the important causes of paraplegia in India. The diagnosis usually rests on clinical history and examination, and on laboratory findings in the cerebro-spinal fluid (CSF). Few descriptive reports are available of the myelographic appearance, with water-soluble contrast media, in tuberculous radiculomyelitis (arachnoiditis). A retrospective review of 21 myelograms and 10 computed tomographic (CT) myelograms, in 14 patients with tuberculous radiculomyelitis, was carried out, with a view to describing, in detail, the radiographic features. An attempt was made to assess the use of the radiologic procedures in diagnosis and follow up in these patients. Conventional myelographic findings included block (8/14), irregular sub-arachnoid space (9/14), filling defects (8/14), sluggish contrast flow (2/14), root thickening (3/14) and atrophic cord (2/14). Computed tomographic myelography showed reduced contrast density in portions of the opacified CSF ring around the cord in affected region (6/7) and, in addition, demonstrated septa and adhesions. Intravenous contrast CT was not found to be useful (2/2). Follow-up studies showed partial resolution (3/6), deterioration (1/6) and status quo of radiological findings (2/6). Although these changes can be seen in chronic radiculomyelitis (arachnoiditis) from other causes, such as leukaemic infiltration/lymphoma, other chronic central nervous system infections and iatrogenic causes, including repeated intrathecal injections, conventional myelography appeared to be useful for diagnosis and follow up in tuberculous radiculomyelitis (arachnoiditis). 12 refs., 1 tabs., 10 figs

  5. Anterior chest wall tuberculous abscess: a case report

    Directory of Open Access Journals (Sweden)

    Papavramidis Theodossis S

    2007-11-01

    Full Text Available Abstract The granulomatous inflammation of tuberculosis usually involves the lungs and the hilar lymph nodes. Musculoskeletal tuberculosis (TB occurs in 1–3% of patients with TB, while TB of the chest wall constitutes 1% to 5% of all cases of musculoskeletal TB. Furthermore, nowadays it is rarer to find extrapulmonary TB in immunocompetent rather that non-immunocompetent patients. The present case reports a fifty-six-year-old immunocompetent man with an anterior chest wall tuberculous abscess. The rarity of the present case relates both to the localization of the tuberculous abscess, and to the fact that the patient was immunocompetent. The diagnosis of musculoskeletal tuberculous infection remains a challenge for clinicians and requires a high index of suspicion. The combination of indolent onset of symptoms, positive tuberculin skin test, and compatible radiographic findings, strongly suggests the diagnosis. TB, however, must be confirmed by positive culture or histologic proof. Prompt diagnosis and treatment are important to prevent serious bone and joint destruction.

    Tuberculous spondylitis (TBS) is the most common form of extra-pulmonary tuberculosis. The mainstay of TBS management is anti-tuberculous chemotherapy. Most of the patients with TBS are treated conservatively; however in some patients surgery is indicated. Most common indications for surgery include neurological deficit, deformity, instability, large abscesses and necrotic tissue mass or inadequate response to anti-tuberculous chemotherapy. The most common form of TBS involves a single motion segment of spine (two adjoining vertebrae and their intervening disc). Sometimes TBS involves more than two adjoining vertebrae, when it is called multilevel TBS. Indications for correct surgical management of multilevel TBS is not clear from literature. We have retrospectively reviewed 87 patients operated in 10 years for multilevel TBS involving the thoracolumbar spine at our spine unit. Two types of surgeries were performed on these patients. In 57 patients, modified Hong Kong operation was performed with radical debridement, strut grafting and anterior instrumentation. In 30 patients this operation was combined with pedicle screw fixation with or without correction of kyphosis by osteotomy. Patients were followed up for correction of kyphosis, improvement in neurological deficit, pain and function. Complications were noted. On long-term follow-up (average 64 months), there was 9.34 % improvement in kyphosis angle in the modified Hong Kong group and 47.58 % improvement in the group with pedicle screw fixation and osteotomy in addition to anterior surgery (p debridement and anterior column reconstruction.

    Objective: To compare the effectiveness, safety and morbidity of strictureplasty with resection anastomosis in patients with tuberculous small gut strictures. Subjects and Methods: Thirty patients who presented with intestinal obstruction due to tuberculous strictures, and underwent either resection anastomosis or strictureplasty where included in the study. Data was collected on a proforma and analyzed using software SPSS (version 8.0). Chi-square and t-test were used to test the hypothesis. Main outcome measures included the presence or absence of postoperative leakage anastomosis, wound infection, recurrence of intestinal obstruction and postoperative study. Results: Chi-square test applied to see the effectiveness showed no significant difference (p>0.5) between the two procedures. t-Test on the score of morbidity also showed no significant difference (p>0.5) between the two procedures. Conclusion: Both procedures performed were equally effective and had equal morbidity in cases of intestinal tuberculous strictures. Strictureplasty is superior to resection anastomosis in cases of multiple strictures as it conserves gut length and can even be performed safely in cases with coexistent gut perforation. (author)

    Radiographs of chest may hardly differentiate the tuberculous mediastinal lymphadenopathy in children or adults with other mediastinal tumors sometimes when markedly enlarged mediastinal lymph node is the main findings of tuberculosis. 6 cases of tuberculous mediastinal lymphadenopathy was collected which was confirmed histopathologically and of which findings in chest films are indistinguishable with other mediastinal tumors especially lymphomas. After analysing the findings in chest films, the followings: could be found 1) The locations of the lesions are mainly hilar and superior mediastinum but there are also many variations of them, so there are of no significance in differential diagnosis with other mediastinal tumors. 2) The contours of the lesions are unilateral in 5 cases, and scalloped or diffusely widened appearance in all cases. 3) When mediastinal lymphadenopathy is the sole evidence of tuberculosis and even when additional lesions are noted in lung parenchyme or pleura, occasional lyes chest x-ray only is insufficient to differentiate the lesion with other mediastinal tumors including lymphomas. 4) Considering the frequency of the tuberculosis in this country, whenever one suspects any mediastinal tumors in chest x-ray one should include the possibility of tuberculous mediastinal lymphadenopathy in differential diagnosis.

    Initial presentation with primary spinal involvement in chronic recurrent multifocal osteomyelitis of childhood (CRMO) is rare. Our objective was to review the imaging appearances of three patients who had CRMO who initially presented with isolated primary spinal involvement.Design and patients The imaging, clinical, laboratory and histology findings of the three patients were retrospectively reviewed. Imaging included seven spinal MR imaging scans, one computed tomography scan, nine bone scans, two tomograms and 16 radiographs. These were reviewed by two musculoskeletal radiologists and a consensus view is reported. All three patients presented with atraumatic spinal pain and had extensive bone spinal pathology. The patients were aged 11, 13 and 12 years. There were two females and one male.Results and conclusions The initial patient had thoracic T6 and T8 vertebra plana. Bone scan showed additional vertebral body involvement. Follow-up was available over a 3 year period. The second patient had partial collapse of T9 and, 2 years later, of C6. Subsequently extensive multifocal disease ensued and follow-up was available over 8 years. The third patient initially had L3 inferior partial collapse and 1 year later T8 involvement with multifocal disease. Follow-up was available over 3 years. The imaging findings of the three patients include partial and complete vertebra plana with a subchondral line adjacent to endplates associated with bone marrow MR signal alterations. Awareness of the imaging appearances may help the radiologist to include this entity in the differential diagnosis in children who present with spinal pathology and no history of trauma. Histopathological examination excludes tumor and infection but with typical imaging findings may not always be necessary. (orig.)

    of the entire vertebral bodies (L-2) were used for histomorphometry. The other iliac crest biopsies and the L-3 were destructively tested by compression. High correlation was found between BV/TV or Tb.Sp and vertebral bone strength (absolute value of r = 0.86 in both cases). Addition of Tb.Th significantly....... No gender-related differences were found in any of the relationships. Neither static histomorphometry nor biomechanical testing of iliac crest bone biopsies is a good predictor of vertebral bone strength.......The study investigates the relationship between static histomorphometry and bone strength of human lumbar vertebral bone. The ability of vertebral histomorphometry to predict vertebral bone strength was compared with that of vertebral densitometry, and also with histomorphometry and bone strength...

    The procedure using 99m Tc-MDP (Methylene Diphosphonate) was divided into two parts: a dynamic portion designed to obtain data to calculate the blood flow to the specific bones or joints being evaluated and a static portion that consisted of a routine bone scan. This method was applied to 30 patients with osteomyelitis of various bones. The dynamic study showed a pronounced increase in flow on the affected side. This was accompanied always by a significant increase in flow in the areas proximal and distal to the area of involvement. Ten patients had sequential scans during the course of antibiotic treatment. In all ten patients the flow became more symmetrical during the course of the treatment indicating the effect of the antibiotics. In seven of these patients the flow became completely symmetrical at the end of the therapy. The static bone images remained unchanged during the antibiotic treatment and did not reflect its effect. The method of dynamic bone scanning in osteomyelitis thus provides a way to determine the effectiveness of antibiotic therapy

    Acute hematogenous osteomyelitis is a bacterial infectious disease which mainly affects the paediatrics age group. The incidence seems to decline through the last decade. The authors analyzed the clinical, bacteriological and radiological features of acute hematogenous osteomyelitis in 49 young children. Their age ranged from 12 days to 2.9 years (19 new-born and 30 babies). The most affected locus was the femur (46.9 %), followed by the humerus (40.9 %) and tibia (6.2 %). The adjacent joint was involved in 38.8 %. Up to the third day after onset of symptoms were admitted 32 children (65.3 %). A bacteriological diagnosis has been achieved in only 19 cases (38.8 %) which underwent different surgical procedures. Staphylococcus aureus (9 children; 64.3 %) was the most common causative microbe. Radiological characteristic showed mainly widening of joints, destruction of cartilage, bone destruction and osteoporosis. The median duration of antibiotic therapy was 31 days. Nine children underwent needle aspiration while another 10 required locus incision or open surgery with debridement or sequestrectomy. Definitive clinical restoration was observed in 42 cases (85.7%). (authors)

  13. Chronic multifocal osteomyelitis: Is infectious causation a moot point?

    2011-09-01

    Full Text Available Summary: Chronic multifocal osteomyelitis (CMO is an uncommon disease entity with descriptions possibly emanating from the medical literature over one century ago, and there are numerous disease entities which have been historically detailed and which are probably synonymous. The illness is one of chronicity with exacerbating and remitting focal bony lesions. The differential diagnosis for a bony lesion which ultimately proves to be CMO is initially quite broad. There is no absolute pathognomonic clinical finding, and the diagnosis is highly dependent on clinical course, histopathology, and an absence of microbial infection. Recent studies have focused on immune dysfunction or dysregulation, and there are now many other diseases which are inflammatory in nature and which have been diagnosed among patients with CMO. Despite the aforementioned, the potential for direct infectious causation or indirect causation by infectious stimulation of immunity cannot be entirely excluded. Infection as a mechanism for pathogenesis must continue to be entertained. Multi-centre studies are key to future research. Key words: Osteomyelitis, Infection, SAPHO, Immunity

    Full Text Available Dental implants are now broadly used to replace missing teeth, and the presence of infectious complications is rising. Dental implant therapy as a local risk factor for the onset of osteomyelitis and its management have not been widely explored. Here, we report an unusual case of mandibular suppurative osteomyelitis caused by Streptococcus intermedius in a healthy and immunocompetent patient secondary to mandibular implants. We describe how surgery combined with systemic application of antibiotics allowed conservation of the dental implants in the mandibular bone, discuss the probable source of contamination, and present the follow-up of the osteomyelitis.

    1984-01-01

    The records of 69 patients who had 86 delayed, static radionuclide bone images for suspected osteomyelitis were studied to determine the effects of this procedure on diagnosis and treatment. Sensitivity, specificity, and positive predictive value were lower than reported in several other studies. When osteomyelitis was unlikely, imaging was either negative or falsely positive and rarely affected treatment. In 46 cases where osteomyelitis was more likely, imaging potentially changed therapy in 19 but was unhelpful or misleading in 15. Static-phase images with ''definite'' interpretations, particularly when negative, are specific, but ''equivocal'' studies may lead to diagnostic and therapeutic errors. When ostemyelitis is improbable, imaging rarely changes diagnosis or therapy

    Cryptococcus neoformans is a fungal pathogen associated with advanced HIV disease and other disorders associated with immune dysfunction. The pulmonary and the central nervous system are the most common manifestations of the disease. Localised osteomyelitis as the sole manifestation of extrapulmonary disease is rare. Herein, we present five cases of Cryptococcus osteomyelitis as the only manifestation of extrapulmonary disease. We also identified 84 additional cases of isolated cryptococcal osteomyelitis in the literature. Using these data, we have made some general recommendations regarding an approach to treatment of this uncommon clinical entity. © 2016 Blackwell Verlag GmbH.

    Full Text Available Objective: To evaluate the utility of adenosine deaminase activity in the pleural fluid for the diagnosis of tuberculous pleural effusion from empyema of non-tubercular origin. Method: A retrospective analysis of data was performed on patients who were diagnosed to have tuberculous pleural effusion and empyema of non tubercular origin. Among 46 patients at Kasturba Hospital, Manipal University, Manipal, Karnataka, India, from November 201 2 to February 2013 who underwent pleural fluid adenosine deaminase estimation, 25 patients with tuberculous pleural effusion and 21 patients with empyema were diagnosed respectively. Adenosine deaminase in pleural fluid is estimated using colorimetric, Galanti and Guisti method. Results: Pleural fluid Adenosine Deaminase levels among tuberculous pleural effusion(109.38依 53.83 , empyema (141.20依71.69 with P=0.27. Conclusion: Pleural fluid adenosine deaminase alone cannot be used as a marker for the diagnosis of tuberculous pleural effusion.

  20. Clinical Application of Antimicrobial Bone Graft Substitute in Osteomyelitis Treatment: A Systematic Review of Different Bone Graft Substitutes Available in Clinical Treatment of Osteomyelitis

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Osteomyelitis is a common occurrence in orthopaedic surgery, which is caused by different bacteria. Treatment of osteomyelitis patients aims to eradicate infection by debridement surgery and local and systemic antibiotic therapy. Local treatment increases success rates and can be performed with different antimicrobial bone graft substitutes. This review is performed to assess the level of evidence of synthetic bone graft substitutes in osteomyelitis treatment. According to the PRISMA statement for reporting systematic reviews, different types of clinical studies concerning treatment of osteomyelitis with bone graft substitutes are included. These studies are assessed on their methodological quality as level of evidence and bias and their clinical outcomes as eradication of infection. In the fifteen included studies, the levels of evidence were weak and in ten out of the fifteen studies there was a moderate to high risk of bias. However, first results of the eradication of infection in these studies showed promising results with their relatively high success rates and low complication rates. Due to the low levels of evidence and high risks of bias of the included studies, these results are inconclusive and no conclusions regarding the performed clinical studies of osteomyelitis treatment with antimicrobial bone graft substitutes can be drawn.

    2017-09-01

    Full Text Available As many people keep small dogs as pets, dog bites are common injuries, accounting for approximately 80%–90% of all animal bite injuries. These injuries usually occur on the upper extremities, most commonly on the fingers. Most of these injuries appear as simple lacerations or abrasions of the skin. Common symptoms include inflammatory reactions of the soft tissue, such as pain, swelling, erythema, and cellulitis. However, the complications of small dog bites may include joint or cartilage injuries, including acute osteomyelitis. Once osteomyelitis develops, it is difficult to diagnose since it has a latency period of approximately 2 weeks. Plain radiography, magnetic resonance imaging, and 3-phase bone scans should be performed when acute osteomyelitis is suspected, and broad-spectrum empiric antibiotic treatment should be administered for approximately 8–12 weeks. We report 3 very rare cases of acute osteomyelitis that occurred after a dog bite injury.

    The case of a 17-year-old girl with sickle cell anaemia who presented with extensive osteomyelitis due to actinomycetes is reported. Osteomyelitis in the long bones due to actinomycosis is extremely rare. A review of the literature reveals only six cases in which actinomycetes have been isolated from lesions affecting a long bone. The occurence of this condition in sickle cell haemoglobinopathy has not been previously reported. (orig.)

    Chronic osteomyelitis is still a big reconstructive challenge. Even with standard care, therapeutic failures and recurrences are common. Multiple techniques of tissue transfer have increased the success rate. This study recommends free muscle transfers into the intramedullary bone cavities for treatment of chronic osteomyelitis. The review included 29 patients that were treated for chronic osteomyelitis. Osteomyelitis was located at the femur in four patients, the tibia in 22 patients, and the foot in three patients. Dead bone and scar tissue were replaced with durable free muscle flap with special attention to fill the dead space. The average age of these patients was 48.5 years old (range = 23-70 years old). The average duration of osteomyelitis was 8.2 years (range = 1-45 years). Gracilis was applied in 20 cases (69%), latissimus dorsi was used in five cases (17.2%), and rectus abdominis was performed in four cases (13.8%). There was one flap failure, one partial superficial flap necrosis, two arterial thrombosis, and one venous thrombosis. All the remaining 28 muscle flaps survived. From 1-10 years follow-up, there was one recurrence of the osteomyelitis in the distal end of the intra-medullary cavity of a femur after reconstructing using the gracilis flap. The present study demonstrated that free intramedullary muscle transfers are effective in providing a high rate of success in the treatment of chronic osteomyelitis. The secondary filling of the intramedullary cavity after extensive removal of all infected bony sequesters has proven to give a long-term arrest of chronic osteomyelitis.

    In the period between 1970 and 1982, 6 carcinomas in scar tissue and 2 pseudocarcinomatous skin papillomatoses were found on the basis of chronic osteomyelitides. Amputation specimens of two carcinomas and one papillomatosis were examined by arteriography. Macroscopically carcinomas in scar tissue showed an unspecific appearance and microscopically a scarefied and partly pathological vascular appearance. Pseudocarcinomatous skin papillomatosis was distinctly hypervascular. Therefore, indications with regard to the localisation of an required exploratory excision can only be obtained from the vascular appearance of papillomatosis but not in case of a scar tissue carcinoma after osteomyelitis. Due to the overall bad blood circulation osteomyelitic scar tissue carcinoma scarcely reacts positively to a chemotherapeutic treatment. (orig.) [de

    Elephantiasis nostras verrucosa represents an infrequent clinical entity with cutaneous changes characterized by dermal fibrosis, hyperkeratotic verrucous and papillamotous lesions resulting from chronic non-filarial lymphedema secondary to infections, surgeries, tumor obstruction, radiation, congestive heart failure, and obesity. Although recurrent streptococcal lymphangitis is believed to play a critical role in the origin of elephantiasis nostras verrucosa, the exact pathogenesis of the disorder is not yet clear. Therapeutic efforts should aim to reduce lymph stasis, which will also lead to improvement of the cutaneous changes but unfortunately there is no specific treatment for advanced cases. In this report, we present a patient who was treated by below knee amputation as a result of elephantiasis nostras verrucosa complicated with chronic tibial osteomyelitis.

    2012-01-01

    Dental injuries to or abnormalities in functionally important teeth and associated bones in predators may significantly reduce the ability to kill and consume prey (Lazar et al. 2009). This impairment is likely exacerbated in coursing predators, such as Gray Wolves, that bite and hold onto fleeing and kicking prey with their teeth. Damage to carnassials (upper fourth premolar, P4, and lower first molar, M1) and associated bones in Gray Wolves may especially inhibit the consumption of prey because these teeth slice meat and crush bone. Here I report maxillary osteomyelitis involving the carnassials in a wild Gray Wolf from northeastern Minnesota of such severity that I hypothesize it ultimately caused the Gray Wolf to starve to death.

    Full Text Available Sickle cell anaemia (SCA is a common haemoglobinopathy among people from the Middle East, the Afro-Caribbean region, the Mediterranean and East India. While osteomyelitis of the long bones is a welldocumented complication of SCA, there are few documented cases of SCA patients presenting with jaw osteomyelitis. We report three SCA patients with chronic jaw osteomyelitis who presented to the Department of Oral Health, Sultan Qaboos University Hospital, Muscat, Oman, between 2009 and 2013. Two of the patients had osteomyelitis of the mandible and the third had osteomyelitis of the maxilla. In addition, a brief review of the literature is presented focusing on the clinical presentation, diagnosis and management of jaw osteomyelitis among patients with SCA.

    Full Text Available Osteomyelitis is commonly caused by Staphylococcus aureus. Both erythromycin and curcumin can suppress S. aureus growth, but their roles in osteomyelitis are barely studied. We aim to explore the activities of erythromycin and curcumin against chronical osteomyelitis induced by methicillin-resistant S. aureus (MRSA. Chronicle implant-induced osteomyelitis was established by MRSA infection in male Wistar rats. Four weeks after bacterial inoculation, rats received no treatment, erythromycin monotherapy, curcumin monotherapy, or erythromycin plus curcumin twice daily for 2 weeks. Bacterial levels, bone infection status, inflammatory signals and side effects were evaluated. Rats tolerated all treatments well, with no death or side effects such as, diarrhea and weight loss. Two days after treatment completion, erythromycin monotherapy did not suppress bacterial growth and had no effect in bone infection, although it reduced serum pro-inflammatory cytokines tumor necrosis factor (TNF-α and interleukin (IL-6. Curcumin monotherapy slightly suppressed bacterial growth, alleviated bone infection and reduced TNF-α and IL-6. Erythromycin and curcumin combined treatment markedly suppressed bacterial growth, substantially alleviated bone infection and reduced TNF-α and IL-6. Combination of erythromycin and curcumin lead a much stronger efficiency against MRSA induced osteomyelitis in rats than monotherapy. Our study suggests that erythromycin and curcumin could be a new combination for treating MRSA induced osteomyelitis.

    Osteomyelitis is an inflammation of the bone marrow mainly caused by bacteria such as Staphylococcus aureus. It typically affects long bones, e.g. femora, tibiae and humeri. Recently micro-computed tomography (μCT) techniques offer the opportunity to investigate bone micro-architecture in great detail. Since there is no information on long bone microstructure in osteomyelitis, we studied historic bone samples with osteomyelitis by μCT. We investigated 23 femora of 22 individuals suffering from osteomyelitis provided by the Collection of Anatomical Pathology, Museum of Natural History, Vienna (average age 44 ±19 years); 9 femora from body donors made available by the Department of Applied Anatomy, Medical University of Vienna (age range, 56-102 years) were studied as controls. Bone microstructure was assessed by μCT VISCOM X 8060 II with a minimal resolution of 18 μm. In the osteomyelitic femora, most prominent alterations were seen in the cortical compartment. In 71.4 % of the individuals with osteomyelitis, cortical porosity occurred. 57.1 % of the individuals showed cortical thinning. In 42.9 % trabecularisation of cortical bone was observed. Osteomyelitis is associated with severe alterations of cortical bone structure otherwise typically observed at old age such as cortical porosity and cortical thinning. (orig.)

    2010-02-01

    Full Text Available Hepatic tuberculosis is an uncommon form of extrapulmonary tuberculosis, particularly when it presents in the form of liver abscess. Here, we report a 64-year-old man who was admitted to our hospital having experienced intermittent chills for 3 months. Aspiration of the liver abscess revealed neither bacteria nor acid-fast bacilli, but pus and granulation tissue were found. Antituberculous therapy was started empirically and cultures of the abscess confirmed the presence of Mycobacterium tuberculosis 3 weeks later. We suggest that tuberculous liver abscess should be considered in patients not showing typical features or who fail to respond to antibiotics.

    Between 1975 and 1996, 14 patients (11 females, 3 males) with vertebral hemangioma received treatment with radiotherapy. Thirteen patients had a history of back pain or lumbago and 2 patients had neurological symptoms such as sensory impairment or paraplegia. The standard dose administered was 36 Gy in 18 fractions (five treatments per week). In the 13 patients with pain, this was completely or partially relieved. The condition of a man with hypesthesia of the legs deteriorated and a woman with paraplegia who was treated with decompressive laminectomy followed by radiotherapy recovered completely after irradiation. CT scan before irradiation showed thickened trabeculae as small punctate areas of sclerosis in all patients. At MR imaging before irradiation, T2-weighted MR images showed areas of high intensity in all patients and MR images demonstrated lesion enhancement. However, none of the patients who were treated successfully with radiation demonstrated any changes of the affected vertebra in the conventional radiographic films, CT scan or MR imaging, even 5 years after irradiation. Radiological imaging is indispensable for the diagnosis of vertebral hemangiomas but does not appear to be useful for evaluating the effects of radiotherapy. (orig.)

    2010-01-01

    Objective: To explore differential diagnostic value of procalcitonin (PCT), adenosine deaminase (ADA) in pleural fluid and serum for tuberculous pleural effusions. Methods: The concentrations of PCT and ADA both in serum and pleural fluid in one hundred and twenty-eight patients with pleural effusion were detected. These patients were divided into three groups. Fifty-two patients with tuberculous plueral effusion were composed of the tuberculous group. Twenty-two patients with parapneumonic effusion composed the pneumonic group and forty patients with malignant pleural effusion and fourteen patients with heart faliure composed of the control group. Results: There were no statistically significant differences in serum PCT among the three groups (P > 0.05). PCT of pleural fluid was significantly increased in tuberculous and parapneumonic groups compared to the control group (P < 0.05). ADA activities in tuberculous serum and pleural fluid were both higher than those in the parapneumonic and the control groups (P < 0.01). The ratio of ADA in pleural fluid and serum (P /S) was calculated. The diagnostic sensitivity and specificity of P /S (cut-off value 1.27) were 92.3% and 100% respectively for tuberculous pleural effusions calcuted by receiver operating curve. Conclusion: Combined measurements of PCT and ADA in pleural fluid are useful in diagnosing tuberculous pleural effusions. (authors)

Place and Duration of Study: Paediatric Medicine, Unit-I, Bahawal Victoria Hospital, Bahawalpur, from May 2006 to March 2007. Methodology: A total of 100 children admitted through emergency in Paediatric Medicine, Unit-I, were included who were having fever and features suggestive of central nervous system (CNS) infection. Lumbar puncture was done in all patients after written consent. Findings of lumbar puncture were taken as gold standard for the diagnosis of TBM. MKJSC was applied on each patient and accuracy determined against the gold standard. Results: Out of 100 children, 47 were diagnosed as TBM on the basis of CSF results. All children had scored 0-7 or above according to MKJSC. A score 1-2, 3-4, 5-6 and 7 or more was obtained in 23, 25, 30 and 22 children respectively. Children who had scored 5 or more received ATT. Accuracy of MKJSC was calculated to be 91%. Conclusion: MKJSC is a simple and accurate tool to improve tuberculous meningitis case detection rate in children. (author)

    Tuberculosis infection caused by Mycobacterium tuberculosis or other Mycobacterium species is a major communicable disease worldwide. We evaluated the epidemiology of tuberculous peritonitis to determine diagnostic features and factors related to late diagnosis. We retrospectively reviewed 211 tuberculous peritonitis cases diagnosed between January 1999 and December 2009. Clinical features, laboratory data, and diagnostic methods were analysed. Subjects included 115 males (54.5%) and 96 females (45.5%) with median age 61.0 years (range 43-72) and 29.2 days mean duration from symptoms to diagnosis. Disease histories included end-stage renal disease (20.9%), pulmonary tuberculosis (36.0%) and liver cirrhosis (23.7%). Most common symptoms were abdominal distension (80.1%), abdominal pain (68.7%) and weight loss (45.5%). Most common signs were ascites (62.6%) and fever (55.5%). One-year survival rate was 89.9%; 21 patients died during follow-up. Mortality risk was higher in patients with more concomitant diseases, including liver cirrhosis, AIDS, chronic steroid use, alcoholism, GI bleeding, haemoptysis, period from symptom presentation to treatment, secondary bacterial peritonitis requiring emergent operation. Increased duration between symptoms and definitive diagnosis increases mortality risk. Early diagnosis and prompt initiation of anti-tuberculosis therapy improve prognosis. Neutrophil-predominant ascites influences poor prognosis when correlated with secondary bacterial peritonitis. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    Eleven patients (ten male, one female; range, 2-56 years) presented with posterior circulation ischemic symptoms and were evaluated with computed tomography (CT) (eta=11), arteriography (eta=11), and magnetic resonance (MR) imaging (eta=6). Angiography showed dissection of a vertebral artery (eta=8), a basilar artery (eta=1), or a combination of both (eta=2). On CT and/or MR images, infarctions were demonstrated in ten of 11 cases. Most frequently involved were the thalmus (eta=7), cerebellum (eta=6), occipital lobes (eta=4), and pons (eta=3). The site of infarction did not correlate with the side or site of angiographic abnormality. In six cases evaluated by all modalities, MR imaging showed more extensive and widespread infarction than did CT and also showed whether or not the infarcts were hemorrhagic. MR imaging was able to demonstrate the presence of intramural dissecting hematoma prior to angiography and to indicate whether or not flow was reconstituted on follow-up examination

    The matrix metalloproteinase (MMP) family belongs to the metzincin clan of zinc-dependent metallopeptidases. Due to their enormous implications in physiology and disease, MMPs have mainly been studied in vertebrates. They are engaged in extracellular protein processing and degradation, and present extensive paralogy, with 23 forms in humans. One characteristic of MMPs is a ~165-residue catalytic domain (CD), which has been structurally studied for 14 MMPs from human, mouse, rat, pig and the oral-microbiome bacterium Tannerella forsythia. These studies revealed close overall coincidence and characteristic structural features, which distinguish MMPs from other metzincins and give rise to a sequence pattern for their identification. Here, we reviewed the literature available on MMPs outside vertebrates and performed database searches for potential MMP CDs in invertebrates, plants, fungi, viruses, protists, archaea and bacteria. These and previous results revealed that MMPs are widely present in several copies in Eumetazoa and higher plants (Tracheophyta), but have just token presence in eukaryotic algae. A few dozen sequences were found in Ascomycota (within fungi) and in double-stranded DNA viruses infecting invertebrates (within viruses). In contrast, a few hundred sequences were found in archaea and >1000 in bacteria, with several copies for some species. Most of the archaeal and bacterial phyla containing potential MMPs are present in human oral and gut microbiomes. Overall, MMP-like sequences are present across all kingdoms of life, but their asymmetric distribution contradicts the vertical descent model from a eubacterial or archaeal ancestor.

    2011-03-01

    Vertebral haemangiomas are generally benign asymptomatic vascular tumours seen commonly in the adult population. Presentations in paediatric populations are extremely rare, which can result in rapid onset of neurological symptoms. We present a highly unusual case of an aggressive paediatric vertebral haemangioma causing significant cord compression. A 13-year-old boy presented with only 2 weeks duration of progressive gait disturbance, truncal ataxia and loss of bladder control. Magnetic resonance imaging (MRI) of the spine revealed a large vascular epidural mass extending between T6 and T8 vertebral bodies. Associated displacement and compression of the spinal cord was present. A highly vascular bony lesion was found during surgery. Histopathology identified this tumour to be a vertebral haemangioma. We present an extremely unusual acute presentation of a paediatric vertebral haemangioma. This study highlights the need for early diagnosis, MRI for investigation and urgent surgical management. © Springer-Verlag 2011

    Background Pyogenic bacteria and especially Staphylococcus aurous (S. aurous) are the most common cause of chronic osteomyelitis. Not only treatment protocol of chronic osteomyelitis occasionally is amiss but also this malady responds to treatment difficultly. Objectives This study investigates antibiotic resistance pattern of S. aurous isolated from Iranian patients who suffer from chronic osteomyelitis by two methods: disk diffusion (Kirby bauyer) and E-test (Epsilometer test) to find Vancomycin susceptibility and MIC (Minimum inhibitory concentration). Patients and Methods One hundred and thirty one patients who suffer from chronic osteomyelitis which have been referred to both governmental and private hospitals at 2010 were tried out for culturing of osteomyelitis site (sites). Antibiotic susceptibility and MIC of isolated bacteria were investigated by Kirby bauyer and E-test respectively. Results Samples were collected from bone (73.4%), surrounding tissue (14.6%) and wound discharge (12%). S. aureus was isolated from 49.6% of the samples. According to disc diffusion, methicillin resistance S. aureus (MRSA) was 75% and Vancomycin resistance S. aurous (VRSA) was 0% and based on MIC, MRSA was 68.5% and VRSA was 0%. According to MIC experiments, maximum sensitivity was against to Vancomycin (90.2%) and ciprofloxacin (54.4%) respectively but based on disc diffusion, maximum sensitivity was against to Vancomycin (97.7%) and ciprofloxacin (43.2%), respectively (P = 0.001). E-test (9.8%) in comparison with Disc diffusion (2.3%) showed higher percent of intermediate susceptibility to Vancomycin (P = 0.017). Conclusions Comparison of antibiograms and MICs showed that Kirby bauyer technique especially for detection of VISA strains is not reliable comparison with E-test. Already VRSA strains have not detected in Iranian chronic osteomyelitis, Thus Vancomycin is the first choice for chronic osteomyelitis empirical therapy in Iran yet. PMID:23483042

    Chronic osteomyelitis is a challenging setback to the orthopedic surgeons in deciding an optimal therapeutic strategy. Conversely, patients feel frustrated of the therapeutic outcomes and development of adverse drug effects, if any. Present investigation deals with extensive approach incorporating in vivo animal experimentation and human application to treat chronic osteomyelitis, using antibiotic loaded porous hydroxyapatite scaffolds. Micro- to macro-porous hydroxyapatite scaffolds impregnated with antibiotic ceftriaxone–sulbactam sodium (CFS) were fabricated and subsequently evaluated by in vivo animal model after developing osteomyelitis in rabbit tibia. Finally 10 nos. of human osteomyelitis patients involving long bone and mandible were studied for histopathology, radiology, pus culture, 3D CT etc. up to 8–18 months post-operatively. It was established up to animal trial stage that 50N50H samples [with 50–55% porosity, average pore size 110 μm, higher interconnectivity (10–100 μm), and moderately high drug adsorption efficiency (50%)] showed efficient drug release up to 42 days than parenteral group based on infection eradication and new bone formation. In vivo human bone showed gradual evidence of new bone formation and fracture union with organized callus without recurrence of infection even after 8 months. This may be a new, alternative, cost effective and ideal therapeutic strategy for chronic osteomyelitis treatment in human patients. - Highlights: • Chronic osteomyelitis is challenging setback to decide optimal therapeutic strategy. • Micro- to macro-porous antibiotic CFS impregnated HAp scaffolds were fabricated. • Complete in vivo animal trial done after developing osteomyelitis in rabbit tibia. • Clinical trial showed fracture union without recurrence of infection after 8 months. • This may be a new, alternative, cost effective and ideal therapeutic strategy.

    Full Text Available Advances in the identification of infections and early diagnosis of Osteomyelitis have led to the improved management of Osteomyelitis. This study was undertaken to determine the bacteriological profile of Osteomyelitis and the antibiotic resistance pattern of various isolates obtained as it is an important cause of morbidity. A total of 50 patients of Osteomyelitis either attending the outpatient department or admitted in the wards of a teaching and tertiary care hospita l in Sikkim from October 2013 to October, 2014 were included in the study. All those patients who were clinically and/ or radiologically suspected of having Osteomyelitis were enrolled as cases. Pus/ pus swabs or sequestrum samples taken aseptically were c ultured aerobically at 37 0 C for 18 - 24 hours in Blood and Mac Conkey agar plates. Culture isolates were identified by a series of standard biochemical reactions. Antibiotic susceptibility was tested on Mueller Hinton agar by Kirby Bauer disc diffusion met hod. Betalactamase production of S. aureus strains were verified by iodometric filter paper and acidometric agar plate methods. S. aureus strains were screened for methicillin resistance by using conventional microbiological methods. S. aureus turned out t o be the most common organism isolated. Other organism isolated were P. Aeruginosa, Proteus spp., Klebsiella spp., E. coli, Enterobacter spp., S. epidermitis, Streptococcus pyogens and Enterococcus spp. Beta - lactamase production and methicillin resistance was seen in S. aureus strains respectively. Multidrug resistance was observed in other strains. Infection caused by Methicillin resistant S. aureus and multidrug resistant organisms are posing a major challenge in the treatment of Osteomyelitis. So, appropriate drug selected by antibiotic sensitivity testing should be used to treat Osteomyelitis

    Tuberculous and Cryptococcal meningitis are common in HIV patients. A highly specific and sensitive rapid test for diagnosis of Tuberculous meningitis especially in setting of HIV is not available in developing countries where the burden of disease is high. We measured ADA (adenosine deaminase) levels using spectrophotometric method in the CSF of HIV patients with meningitis to differentiate Tuberculous meningitis from meningitis due to other causes. Kruskal-Wallis test was used to compare ADA values between tuberculous meningitis (TBM) and nontuberculous (non-TB) meningitis patients and a receiver-operating characteristic (ROC) analysis curve was drawn from these values. Levels of ADA in the CSF of patients with TBM were significantly higher than those in patients with meningitis due to other causes. CSF ADA level determination with a cut-off value of 6 IU/L was found to be highly specific and fairly sensitive test for the diagnosis of TBM in HIV positive patients.

    Extracranial vertebral artery aneurysms are uncommon and are usually associated with trauma or dissection. Primary cervical vertebral aneurysms are even rarer and are not well described. The presentation and natural history are unknown and operative management can be difficult. Accessing aneurysms at the skull base can be difficult and, because the frail arteries are often afflicted with connective tissue abnormalities, direct repair can be particularly challenging. We describe the presentation and surgical management of patients with primary extracranial vertebral artery aneurysms. In this study we performed a retrospective, multi-institutional review of patients with primary aneurysms within the extracranial vertebral artery. Between January 2000 and January 2011, 7 patients, aged 12-56 years, were noted to have 9 primary extracranial vertebral artery aneurysms. All had underlying connective tissue or another hereditary disorder, including Ehler-Danlos syndrome (n=3), Marfan's disease (n=2), neurofibromatosis (n=1), and an unspecified connective tissue abnormality (n=1). Eight of 9 aneurysms were managed operatively, including an attempted bypass that ultimately required vertebral ligation; the contralateral aneurysm on this patient has not been treated. Open interventions included vertebral bypass with vein, external carotid autograft, and vertebral transposition to the internal carotid artery. Special techniques were used for handling the anastomoses in patients with Ehler-Danlos syndrome. Although endovascular exclusion was not performed in isolation, 2 hybrid procedures were performed. There were no instances of perioperative stroke or death. Primary extracranial vertebral artery aneurysms are rare and occur in patients with hereditary disorders. Operative intervention is warranted in symptomatic patients. Exclusion and reconstruction may be performed with open and hybrid techniques with low morbidity and mortality.

    The noninvasive diagnosis of osteomyelitis of the foot in diabetic patients with currently available radiologic and radionuclide imaging techniques is often difficult. Recently, 111In-labeled leukocyte scintigraphy has been proposed as an attractive alternative. Accordingly, the authors retrospectively reviewed 51 111In-labeled leukocyte scans, 49 technetium-99m bone scans, and 49 plain radiographs obtained in 51 adults with diabetes in whom osteomyelitis of the foot was suspected. The sensitivity and specificity of these techniques were evaluated in all patients, as well as in a subgroup of 11 patients with neuroarthropathy. Results with 111In-labeled leukocyte scans were also examined in subsets of patients with soft-tissue ulcers (n = 35) and those receiving antibiotics during investigation (n = 20). Confirmation or exclusion of osteomyelitis was made surgically in 28 patients and clinically in 23. Fourteen patients had osteomyelitis. Bone scans were most sensitive (93%) but least specific (43%); plain radiographs were most specific (83%) but least sensitive (43%). 111In-labeled leukocyte scans were both sensitive (79%) and specific (78%), and remained useful in patients with neuroarthropathy, soft-tissue ulcers, and antibiotic treatment. Poor spatial resolution contributed to the false-negative and false-positive 111In-labeled leukocyte scans, suggesting that this technique should not be interpreted independent of other tests. 111In-labeled leukocyte scans are a valuable diagnostic tool for the diagnosis of pedal osteomyelitis in diabetic patients

    Osteomyelitis is still considered to be one of the major challenges for orthopedic surgeons despite advanced antiseptic surgical procedures and pharmaceutical therapeutics. In this study, hydrophilized poly(methyl methacrylate) (PMMA) bone cements containing Pluronic F68 (EG79PG28EG79) as a hydrophilic additive and vancomycin (F68-VAcements) were prepared to allow the sustained release of the antibiotic for adequate periods of time without any significant loss of mechanical properties. The compressive strengths of the bone cements with Pluronic F68 compositions less than 7 wt% were not significantly different compared with the control vancomycin-loaded bone cement (VAcement). TheF68 (7 wt%)-VAcement showed sustained release of the antibiotic for up to 11 weeks and almost 100% release from the bone cement. It also prohibited the growth ofS. aureus(zone of inhibition) over six weeks (the required period to treat osteomyelitis), and it did not show any notable cytotoxicity. From an animal study using a femoral osteomyelitis rat model, it was observed that theF68 (7 wt%)-VAcement was effective for the treatment of osteomyelitis, probably as a result of the prolonged release of antibiotic from the PMMA bone cement. On the basis of these findings, it can be suggested that the use of Pluronic F68 as a hydrophilic additive for antibiotic-eluting PMMA bone cement can be a promising strategy for the treatment of osteomyelitis. © The Author(s) 2016.

    Full Text Available Fifty-five patients hospitalized for osteomyelitis of the temporal bone between 1990 and 2011 were divided into two study groups: group 1 was patients collected from 1990 to 2001 and group 2 was composed of patients between 2002 and 2011. Clinical diagnostic criteria and epidemiologic data were analyzed to illustrate the altering features of osteomyelitis of the temporal bone. Group 1 patients were characterized by high prevalence of diabetes and more commonly suffered from otalgia, otitis externa and granulation tissue in the external auditory canal and higher positive culture for Pseudomonas aeruginosa. Noticeable changing trends were found between both groups, including declining prevalence of diabetes, fewer patients complaining of pain or presenting with otitis externa, and canal granulation, and increased variety of pathogens in group 2. We should highlight the index of clinical suspicion for osteomyelitis of the temporal bone, even in nondiabetic or immunocompetent patients. Painless otorrhea patients were also at risk of osteomyelitis of the temporal bone, especially patients with previous otologic operation. Increased multiplicity of pathogens amplified the difficulty of diagnosis for osteomyelitis of the temporal bone.

    Kidney transplantation is the treatment of choice for a significant number of patients with end-stage renal disease. Although immunosuppression therapy improves graft and patient's survival, it is a major risk factor for infection following kidney transplantation altering clinical manifestations of the infectious diseases and complicating both the diagnosis and management of renal transplant recipients (RTRs). Existing literature is very limited regarding osteomyelitis in RTRs. Sternoclavicular osteomyelitis is rare and has been mainly reported after contiguous spread of infection or direct traumatic seeding of the bacteria. We present an interesting case of acute, bacterial sternoclavicular osteomyelitis in a long-term RTR. Blood cultures were positive for Streptococcus mitis, while the portal entry site was not identified. Magnetic resonance imaging of the sternoclavicluar region and a three-phase bone scan were positive for sternoclavicular osteomyelitis. Eventually, the patient was successfully treated with Daptomycin as monotherapy. In the presence of immunosuppression, the transplant physician should always remain alert for opportunistic pathogens or unusual location of osteomyelitis.

    Joint replacement infections and osteomyelitis are among the most serious complications in orthopaedics and traumatology. The risk factors for these infections are often bacterial resistance to antimicrobials. One of the few solutions available to control bacterial resistance involves antimicrobials, which have a different mechanism of action from traditional antibiotics. Antimicrobial peptides (AMP) appear to be highly promising candidates in the treatment of resistant infections. We have identified several AMP in the venom of various wild bees and designed analogues that show potent antimicrobial activity and low toxicity against eukaryotic cells. The aim of the present study was to test the efficacy of one of those synthetic peptide analogues for the treatment of acute osteomyelitis invoked in laboratory rats. Femoral cavities of 20 laboratory Wistar rats were infected with Staphylococcus aureus. After 1 week, eight rats received an injectable calcium phosphate carrier alone, another eight rats were treated with a calcium phosphate mixed with AMP, and four rats were left without any further treatment. After another week, all rats were euthanized and radiographs were made of both the operated and healthy limbs. The animals with the carrier alone exhibited more severe acute osteomyelitis on radiographs in comparison to the recipients of the calcium phosphate carrier loaded AMP and untreated infected individuals. Based on the results of the above mentioned experiment, it was concluded that when injected directly into the site of femoral acute osteomyelitis, the calcium phosphate carrier mixed with AMP reduced osteomyelitis signs visible on radiographs.

    Full Text Available Acute clavicle osteomyelitis in children is rare representing <3% of osteomyelitis cases. We treated a 12-year-old boy who presented with acute pain in the right clavicle and high fever for 4 days. MRI showed abnormal signal in the right clavicle with periosteal reaction. Staphylococcus aureus isolated from blood was susceptible to methicillin, clindamycin, and macrolides. Clindamycin was given intravenously for 3 wks and orally for another 3 wks with no recurrence. We reviewed clavicle osteomyelitis cases in children searching PubMed English literature. From a total of 89 studies retrieved, only 6 fulfilled the criteria and were analyzed. Sixteen patients (56% female were included with a median age of 9 yrs (range 2 wks–16 yrs. Osteomyelitis was hematogenous in most cases, with S. aureus being the most frequent cause, isolated from either blood or tissue. Symptoms included fever, swelling, and localized bone tenderness. Antimicrobial therapy lasted for 4–12 weeks (median 7.5. Three patients required drainage or curettage. Recurrence occurred in 1/16 cases (6.2% and persistence of symptoms occurred to 2/16 cases (12.5% reported before 90s with unknown antimicrobial susceptibility of the pathogen. Acute clavicle osteomyelitis mainly affects older children and has generally good prognosis. Staphylococcus aureus is most commonly implicated and surgery may be needed.

    Vacuum-assisted wound closure (VAC) is useful for difficult wound beds, although sites where bleeding or infection is expected are usually regarded as problematic for this therapy. This report outlines the treatment of chronic tibial osteomyelitis (Cierny- Mader type III) due to mixed infection with Nocardia spp and Bacteroi- des fragilis by postoperative VAC therapy direct to the medullary cavity, followed by wound coverage with a gastrocnemius myocutaneous skin flap. A 64-year-old man developed chronic left tibial os- teomyelitis after a work injury. The nonviable tissues were debrided, including a sequestrum. Nocardia spp and B. fragilis were isolated from surgical bone specimens, and chronic tibial osteomyelitis due to mixed infection was diagnosed. Postoperatively, VAC therapy was performed directly to the open medullary cavity of the tibia and sub- sequently covered the residual soft tissue defect with a gastrocnemius myocutaneous flap. The authors could not find any English literature on VAC therapy direct to the medullary cavity combined with transplantation of a myocutaneous flap for osteomyelitis. Nocardia spp can cause a variety of infections, among which osteomyelitis occupies a relatively small percentage. This case raises the possibil- ity of treating chronic tibial osteomyelitis caused by mixed infection with Nocardia spp and B. fragilis by applying postoperative VAC ther- apy directly to the medullary cavity and covering the residual wound with a gastrocnemius myocutaneous flap.

    Full Text Available Study Design. A Case Report. Objective. We present a 15-year-old girl with an acute atypical scoliosis secondary to chronic recurrent multifocal osteomyelitis (CRMO. Summary of Background Data. CRMO is a rare nonpyogenic inflammatory bone condition with unclear aetiology. CRMO mainly affects the metaphyses of long bones, the pelvis, shoulder girdle, and less commonly the spine. Methods. Our case presented with a 6-month history of worsening thoracic back pain, asymmetry of her shoulders and abnormal posture. Whole spine radiographs revealed a right atypical thoracic scoliosis. Magnetic Resonance Imaging showed abnormal signal on the short TI inversion recovery (STIR sequences in multiple vertebrae. A bone biopsy demonstrated evidence of fibrosis and chronic inflammatory changes. Interval MRI scans revealed new oedematous lesions and disappearance of old lesions. Symptoms improved. Results. It is important to consider CRMO as an acute cause of atypical scoliosis. Malignancy, pyogenic infections and atypical presentations of juvenile arthritis need excluding. Conclusion. This 24-month follow-up describes a rare cause of an atypical scoliosis and fortifies the small amount of the currently available literature. The case highlights the relapsing and remitting nature of CRMO with new lesions developing and older lesions burning out. We advise close radiological surveillance and symptomatic management.

    The goal of this investigation is to develop poly(dl-lactide-co-glycolide) (PLGA) nanoparticles for the delivery of antibiotics such as nafcillin to osteoblasts. This is important in order to treat Staphylococcus aureus-mediated osteomyelitis. The latter is often chronic and highly resistant to antibiotics. Nafcillin (a penicillinase-resistant penicillin)-loaded nanoparticles were prepared by a single emulsion/solvent evaporation method. In vitro drug release studies were conducted in an incubator shaker at 37 deg. C in phosphate buffer saline. Drug loading and release were determined by UV-Vis spectroscopy. A viability study was conducted in S. aureus-infected mouse osteoblasts. In vitro release study showed an initial burst release and a second phase of slow release. Following 24 and 48 h of incubation, all formulations of nanoparticles loaded with nafcillin either killed or significantly reduced all of the intracellular bacteria. Our data demonstrate that effective killing of intracellular S. aureus is possible by treating the infected osteoblasts with nanoparticles loaded with nafcillin

    99mTc-labeled antigranulocyte monoclonal antibody Fab' fragments have shown a high sensitivity and specificity for detecting osteomyelitis in prospective studies. We retrospectively evaluated the use of LeukoScan trademark (Immunomedics, Morris Plains, N.J.) in clinical routine for the detection of bone and soft tissue infections and we want to present the results of our findings as well as some of the more interesting cases in this occasion. Imaging infection can be performed fast and easy with 99m Tc-Fab' fragments due to a fast targeting of infection and good background clearance, which increases in imaging quality. The application of 99m Tc-Fab' fragments gives good results in patients with bone and soft tissue infections of peripheral bones, as well as in patients with infected prostheses and infected arthritis. The use of 99m Tc-Fab' fragments should not be limited to these patients only, since good results can also be achieved in patients with infections of vascular grafts, of appendicitis and of endocarditis as well. A higher number of false-negative results has to be expected in case of subacute/chronic infections instead. Independent of the grade of infection acute/subacute infections of the spine always show 'cold lesions'. If cold lesions are used as guide for diagnosing a pathologic finding, an increase in sensitivity together with a decrease in specificity can be achieved. (orig.) [de

    Pleural effusion, an accumulation of fluid in the pleural space, usually occurs in patients when the rate of fluid formation exceeds the rate of fluid removal. The differential diagnosis of tuberculous pleurisy and malignant pleural effusion is a difficult task in high tuberculous prevalence areas. The aim of the present study was to identify novel biomarkers for the diagnosis of pleural fluid using proteomics technology. We used samples from five patients with transudative pleural effusions for internal standard, five patients with tuberculous pleurisy, and the same numbers of patients having malignant effusions were enrolled in the study. We analyzed the proteins in pleural fluid from patients using a technique that combined two-dimensional liquid-phase electrophoresis and matrix assisted laser desorption/ionization-time of flight-mass spectrometry. We identified a total of 10 proteins with statistical significance. Among 10 proteins, trasthyretin, haptoglobin, metastasis-associated protein 1, t-complex protein 1, and fibroblast growth factor-binding protein 1 were related with malignant pleural effusions and human ceruloplasmin, lysozyme precursor, gelsolin, clusterin C complement lysis inhibitor, and peroxirexdoxin 3 were expressed several times or more in tuberculous pleural effusions. Highly expressed proteins in malignant pleural effusion were associated with carcinogenesis and cell growth, and proteins associated with tuberculous pleural effusion played a role in the response to inflammation and fibrosis. These findings will aid in the development of novel diagnostic tools for tuberculous pleurisy and malignant pleural effusion of lung cancer. © Copyright: Yonsei University College of Medicine 2017

    Differentiating tuberculous pleural effusion from other lymphocytic pleural effusions is often challenging. This retrospective study aimed to assess the efficacy and safety of medical thoracoscopy in patients with suspected tuberculous pleural effusion. Between July 2005 and June 2014, patients with pleural effusions of unknown etiologies underwent medical thoracoscopy in our institute after less invasive means of diagnosis had failed. Demographic, radiographic, procedural, and histological data of patients with tuberculous pleural effusion were analyzed. During this 9-year study, 333 of 833 patients with pleural effusion were confirmed to have tuberculous pleurisy. Under thoracoscopy, we observed pleural nodules in 69.4%, pleural adhesion in 66.7%, hyperemia in 60.7%, plaque-like lesions in 6.0%, ulceration in 1.5% of patients with tuberculous pleurisy. Pleural biopsy revealed the presence of Mycobacterium tuberculosis in the pleural tissue or/and demonstration of caseating granulomas in 330 (99.1%) patients. No serious adverse events were recorded, and the most common minor complication was transient chest pain (43.2%) from the indwelling chest tube. Our data showed that medical thoracoscopy is a simple procedure with high diagnostic yield and excellent safety for the diagnosis of tuberculous pleural effusion. Copyright © 2015 Elsevier Ltd.

    Tuberculous cavity is important in diagnosis and observation in the course of pulmonary tuberculosis. Author analyzed the radiologic findings of cavity and average months of negative conversion in AFB culture in 89 cases of initial treatment. The results were as follows: 1. The more number of cavities, the longer period in negative conversion of AFB culture. 2. No relation between sums of diameter and thickness of cavity and average months of negative conversion in AFB culture. 3. In the cases of cavity with air-fluid level took longer period in negative conversion og AFB culture than those of cavity without air-fluid level, significantly. 4. No relation between radiologic findings of cavity and results of chemotherapy for pulmonary tuberculosis.

    It is currently very rare to find mammary involvement in cases of tuberculosis, in either primary or secondary form. Diagnosis is classically clinical and microbiological, and the basic techniques used in imaging diagnosis are mammography and ultrasound. Computed tomography may define the involvement of the thoracic wall in those cases which present as mammary masses adhering to deep levels, and is also able to evaluate accompanying pulmonary disease, if it is present. Traditionally, treatment has consisted of quadrantectomy and specific antibiotic therapy. We present a case of tuberculous mammary abscess secondary to pulmonary disease, which was treated by percutaneous drainage controlled by CT and specific antibiotic therapy. We revise the diagnosis, differential diagnosis and treatment of mammary tuberculosis. (orig.)

    Using multi-antigen print immunoassay and DPP ® VetTB Assay approved in the United States for testing captive cervids and elephants, we analyzed antibody recognition of MPB83 and CFP10/ESAT-6 antigens in Asian elephants (Elephas maximus) infected with Mycobacterium tuberculosis and in white-tailed deer (Odocoileus virginianus), fallow deer (Dama dama), elk (Cervus elaphus), and cattle (Bos taurus) infected with Mycobacterium bovis. Serum IgG reactivity to MPB83 was found in the vast majority of tuberculous cattle and cervid species among which white-tailed deer and elk also showed significant CFP10/ESAT-6 recognition rates with added serodiagnostic value. In contrast, the infected elephants developed antibody responses mainly to CFP10/ESAT-6 with MPB83 reactivity being relatively low. The findings demonstrate distinct patterns of predominant antigen recognition by different animal hosts in tuberculosis. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available In patients with central nervous system disease, life-threatening hyponatremia can result from either the syndrome of inappropriate secretion of antidiuretic hormone or cerebral salt wasting. Clinical manifestations of the two conditions may be similar, but their pathogeneses and management protocols are different. Cerebral salt wasting syndrome is a disorder in which excessive natriuresis and hyponatremia occurs in patients with intracranial diseases. We report a 6-month-old girl with CSWS associated with tuberculous meningoencephalitis. She was diagnosed as having CSWS on the basis of hypovolemia, polyuria, natriuresis, and the relatively high level of fractional excretion of uric acid. Aggressive replacement of urine salt and water losses using 0.9% or 3% sodium chloride was done. Fludrocortisone was started at 0.1 mg twice daily on the seventh day of admission and was continued for 17 days.

    Non-Tuberculous Mycobacterial (NTM) infections occur in HIV-negative patients with or without underlying lung disease. It is generally felt that these organisms are acquired from the environment. Unlike tuberculosis, there are no convincing data demonstrating human-to-human OR animal-to-human transmission of NTM. We report a case of NTM infection in a 38 year old patient with underlying emphysematous lung disease. The case highlights the diagnostic dilemma which occurs when persistent sputum Acid- Fast Bacilli (AFB) smears are positive, but Nucleic acid amplification test is negative. To aid the diagnosis and rule out Pulmonary Tuberculosis as the other differential diagnosis, we applied American Thoracic Society\\/Infectious Disease Society of America (ATS\\/IDSA) guidelines & recommendations1. The decision to treat was taken on basis of CT findings, clinical, microbiologic criteria and expert consultation with Microbiology department at Waterford.

    Chemotherapy studies were undertaken in 180 patients with tuberculous meningitis. They were treated for 12 months with 1 of 3 regimens: the first consisted of streptomycin, isoniazid and rifampicin daily for the first 2 months, followed by ethambutol plus isoniazid for 10 months; in the second, pyrazinamide was added for the first 2 months, and in the third, rifampicin was reduced to twice weekly in the first 2 months. Steroids were prescribed for all the patients in the initial weeks of treatment. Approximately 50% of the patients were aged less than 3 years. On admission, 13% of the patients were classified as stage I, 77% as stage II and 9% as stage III. Cerebrospinal fluid (CSF) culture results were available for all the 180 patients and M. tuberculosis was isolated in 59 (33%). CSF smear results for acid fast bacilli were available only for the 103 patients admitted to the second and the third studies, and of these in 60 (58%) the CSF was positive either by smear or culture. The response to therapy was similar in the 3 studies. Despite administration of rifampicin for 2 months, the mortality was high. In all, 27% of the patients died of tuberculous meningitis, 39% had neurological sequelae and 34% recovered completely. There was a strong association between the stage on admission and the mortality rate, the deaths being highest in stage III. In the first study, when isoniazid was prescribed daily in a dosage of 20 mg/kg, 39% of the patients developed jaundice; however, when the dosage was reduced to 12 mg/kg, the incidence fell to 16%. In the third study, where rifampicin was administered twice a week, the incidence of jaundice was much lower (5%).

    Full Text Available The aims of spinal tuberculosis treatment are to eradicate the disease, to prevent the development of paraplegia and kyphotic deformity, to manage the existing deformity and neurological deficit, to allow early ambulation and to return the patient back to daily life. Methods for the treatment of tuberculosis of vertebra are still controversial. Conservative treatment includes medical therapy as well as external supports and surgery is indicated for deformity of spine, severe pain, or neurological compromise conditions. Most cases in our country were late presentations with disc space already infected, and after débridement there was a large gap needing bone graft to enhance bony fusion and anterior column support. Although the spine was infected, instrumentation posed no additional hazard in terms of tuberculous discitis. Oga et al. reported that M. tuberculosis has low adhesion capability and forms only a few microcolonies surrounded by a biofilm. Moon et al. stated that interbody fusion performed with classical anterior radical surgery per se was ineffective in the correction of kyphosis and did not prevent the increase in kyphosis angle. The present study focuses on collected clinical and radiographic outcomes in ten patients who underwent Posterior Lumbar Interbody Fusion (PLIF for tuberculous lumbosacral spine. All the cases had instability with kyphotic deformity or loss of lordosis. Clinical outcomes were measured by Visual Analogue Scale (VAS, modified MacNab Criteria, and radiographic outcomes (segmental kyphotic angle and total lumbar lordotic, TLL, angle on follow-up to six months. The mean VAS back scores showed decrease, and kyphotic angles and lordotic angles improved. Three cases had excellent results, six good and one fair using the modified MacNab criteria.

    Full Text Available Skull base osteomyelitis can involve the jugular foramen and its associated cranial nerves resulting in specific clinical syndromes. The Collet-Sicard syndrome describes the clinical manifestations of palsies involving cranial nerves IX, X, XI, and XII. We present a rare atypical case of skull base osteomyelitis originating from infection of the middle ear and causing the Collet-Sicard syndrome. Caused by Pseudomonas aeruginosa and Klebsiella pneumoniae, this occurred in an elderly diabetic man subsequent to retention of a cotton swab in an ear with chronic suppurative otitis media. This case report illustrates the possibility of retained cotton swabs contributing to the development of otitis media, skull base osteomyelitis, and ultimately the Collet-Sicard syndrome in the ears of immune-compromised patients with chronically perforated eardrums.

    2016-06-01

    Full Text Available Acute osteomyelitis and septic arthritis are two infections whose frequencies are increasing in pediatric patients. Acute osteomyelitis and septic arthritis need to be carefully assessed, diagnosed, and treated to avoid devastating sequelae. Traditionally, the treatment of acute osteoarticular infection in pediatrics was based on prolonged intravenous anti-infective therapy. However, results from clinical trials have suggested that in uncomplicated cases, a short course of a few days of parenteral antibiotics followed by oral therapy is safe and effective. The aim of this review is to provide clinicians an update on recent controversies and advances regarding the management of acute osteomyelitis and septic arthritis in children. In recent years, the emergence of bacterial species resistant to commonly used antibiotics that are particularly aggressive highlights the necessity for further research to optimize treatment approaches and to develop new molecules able to fight the war against acute osteoarticular infection in pediatric patients.

    Objective:To examine metabolic disorders of major components of organic basis of bone tissue in patients with chronic hematogenous osteomyelitis and response to surgical treatment. Methods: The cubital vein puncture was conducted to take blood for analysis in patients with chronic hematogenous osteomyelitis. The activity of collagenase and hyaluronidase, elastin, elastase and total content of glycosaminoglycans were measured in blood serum. Results: The study revealed an enhancement of catabolic phase of metabolism of the main components in bone organic matrix during the relapse of inflammation. It was evidenced by indicators reflecting the synthetic and catabolic phases of the main components of the connective tissue collagen and glycosaminoglycans. The effective therapeutic treatments led to the reduction and normalization of studied compounds. Conclusions: The initial development of hematogenous osteomyelitis happens in a background of metabolic disorders of the main components of organic matrix of bone tissue, and normalizes upon effective therapy.

    1984-01-01

    Clinical records and scintigrams were reviewed of 18 patients with sickle cell hemoglobinophaties who had undergone combined technetium and gallium scintigraphy during 22 separate episodes of suspected osseous infection. The combined scintigrams were correctly interpreted as indicating osteomyelitis in four studies. Of 18 studies in patients with infarction, the combined scintigrams were correctly interpreted in 16 and showed either no local accumulation of Ga-67 or less accumulation than that of Tc-99m MDP at symptomatic sites. In the other two studies, the scintigrams were falsely interpreted as indicating osteomyelitis and showed congruent, increased accumulation of both Tc-99, MDP and Ga-67. This pattern must be considered indeterminate. Overall, the results indicate that the combination of technetium and gallium scintigraphy is an effective means to distinguish osteomyelitis from infarction in patients with sickle cell hemoglobinopathies

    Osteomyelitis, the most serious complication of the diabetic foot, occurs in about 20 % of patients. Early diagnosis is crucial. Appropriate treatment will avoid or decrease the likelihood of amputation. The objective of this study was to assess the value of FDG PET/CT in diabetic patients with clinically suspected osteomyelitis. Enrolled in this prospective study were 39 consecutive diabetic patients (29 men and 10 women, mean age 57 years, range 28-71 years) with 46 suspected sites of foot infection. Of these 39 patients, 38 had type 2 and 1 type 1 diabetes for 4-25 years, and 28 were receiving treatment with insulin. FDG PET/CT was interpreted for the presence, intensity (SUVmax) and localization of increased FDG foci. Final diagnosis was based on histopathology and bacteriology of surgical samples, or clinical and imaging follow-up. Osteomyelitis was correctly diagnosed in 18 and excluded in 21 sites. Of 20 lesions with focal bone FDG uptake, 2 were false-positive with no further evidence of osteomyelitis. Five sites of diffuse FDG uptake involving more than one bone on CT were correctly diagnosed as diabetic osteoarthropathy. FDG PET/CT had a sensitivity, specificity and accuracy of 100 %, 92 % and 95 % in a patient-based analysis and 100 %, 93 % and 96 % in a lesion-based analysis, respectively, for the diagnosis of osteomyelitis in the diabetic foot. FDG PET/CT was found to have high performance indices for evaluation of the diabetic foot. The PET component identified FDG-avid foci in sites of acute infection which were precisely localized on fused PET/CT images allowing correct differentiation between osteomyelitis and soft-tissue infection.

    There is no consensus on a diagnostic strategy for osteomyelitis underlying pressure ulcers. We conducted a prospective study to assess the accuracy of multiple bone biopsies and imaging to diagnose pelvic osteomyelitis. Patients with clinically suspected osteomyelitis beneath pelvic pressure ulcers were enrolled. Bone magnetic resonance imaging (MRI) and surgical bone biopsies (three or more for microbiology and one for histology per ulcer) were performed. Bacterial osteomyelitis diagnosis relied upon the association of positive histology and microbiology (at least one positive culture for non-commensal microorganisms or three or more for commensal microorganisms of the skin). From 2011 to 2014, 34 patients with 44 pressure ulcers were included. Bacterial osteomyelitis was diagnosed for 28 (82.3%) patients and 35 (79.5%) ulcers according to the composite criterion. Discrepancy was observed between histology and microbiology for 5 (11.4%) ulcers. Most common isolates were Staphylococcus aureus (77.1%), Peptostreptococcus (48.6%) and Bacteroides (40%), cultured in three or more samples in 42.9% of ulcers for S. aureus and ≥20% for anaerobes. Only 2.8% of ulcers had three or more positive specimens with coagulase-negative staphylococci, group B Streptococcus, and nil with enterococci and Pseudomonas aeruginosa. Staphylococcus aureus, Proteus and group milleri Streptococcus were recovered from one sample in 22.8%, 11.4% and 11.4% of ulcers, respectively. Agreement was poor between biopsies and MRI (κ 0.2). Sensitivity of MRI was 94.3% and specificity was 22.2%. The diagnosis of pelvic osteomyelitis relies on multiple surgical bone biopsies with microbiological and histological analyses. At least three bone samples allows the detection of pathogens and exclusion of contaminants. MRI is not routinely useful for diagnosis.

  1. Evaluation of the inflammatory activity in chronic osteomyelitis. Contribution of the scintigraphy with polyclonal antibodies

    Sapienza, Marcelo Tatit

    1996-01-01

    Active chronic osteomyelitis or complicating osteomyelitis (superimposed on diseases that changes the normal bone structure fractures, post-surgery, prosthesis) can be difficult to diagnose by anatomic radiological imaging modalities, like plain radiograph and CT. These diseases frequently cause also increased bone remodeling, leading to nonspecific uptake of Tc-99m-bone scan agents and gallium-67. New radiopharmaceuticals with greater inflammation/infection avidity and specificity are being developed, including the nonspecific polyclonal immunoglobulin (IgG) labeled with technetium-99. Tc-99m-IgG may be available as a ready to use kit, with no reported side effects, low patient absorbed radiation dose and low cost. The mechanism of IgG uptake at the inflammation site has not been fully elucidated yet. Specific (receptor linking, physico-chemical immunoglobulin properties) and nonspecific mechanisms (enhanced vascular permeability and macromolecular exudate) has been suggested. IgG scintigraphy results are affected by the isotope, labeling procedure adopted and characteristics of the inflammatory focus. Nineteen patients with suspected osteomyelitis (active chronic osteomyelitis or violated bone osteomyelitis) were studied by Tc-99m-IgG scintigraphy (directly labeled polyclonal immunoglobulin, Sandoglobuilina - Sandoz). All patients also underwent standard three-phase bone scintigraphy using methylene diphosphonate (Tc-99m-MDP), gallium-67 scintigraphy and plain radiographs. Infection was found in 8 sites. Sensitivity and specificity for Tc-99m-MDP, gallium-67 and Tc 99m-IgG scintigraphy were, respectively, 88 and 36%, 75 and 73%,88 and 82%. All patients with false positive IgG scintigraphies had previous surgery. Other current scintigraphic procedures used in the diagnosis of osteomyelitis are also reviewed. (author)

  3. Parenteral and oral antibiotic duration for treatment of pediatric osteomyelitis: a systematic review protocol

    Science.gov (United States)

    2013-01-01

    Background Pediatric osteomyelitis is a bacterial infection of bones requiring prolonged antibiotic treatment using parenteral followed by enteral agents. Major complications of pediatric osteomyelitis include transition to chronic osteomyelitis, formation of subperiosteal abscesses, extension of infection into the joint, and permanent bony deformity or limb shortening. Historically, osteomyelitis has been treated with long durations of antibiotics to avoid these complications. However, with improvements in management and antibiotic treatment, standard of care is moving towards short durations of intravenous antibiotics prior to enteral antibiotics. Methods/Design The authors will perform a systematic review based on PRISMA guidelines in order to evaluate the literature, looking for evidence to support the optimal duration of parenteral and enteral therapy. The main goals are to see if literature supports shorter durations of either parenteral antibiotics and/or enteral antibiotics. Multiple databases will be investigated using a thorough search strategy. Databases include Medline, Cochrane, EMBASE, SCOPUS, Dissertation Abstracts, CINAHL, Web of Science, African Index Medicus and LILACS. Search stream will include medical subject heading for pediatric patients with osteomyelitis and antibiotic therapy. We will search for published or unpublished randomized and quasi-randomized controlled trials. Two authors will independently select articles, extract data and assess risk of bias by standard Cochrane methodologies. We will analyze comparisons between dichotomous outcomes using risk ratios and continuous outcomes using mean differences. 95% confidence intervals will be computed. Discussion One of the major dilemmas of management of this disease is the duration of parenteral therapy. Long parenteral therapy has increased risk of serious complications and the necessity for long therapy has been called into question. Our study aims to review the currently available

    To assess the clinical findings and hard tissue changes of osteomyelitis of the jaws using computed tomographic (CT) image analysis. We reviewed and interpreted the CT images of 163 patients (64 males and 99 females, age range from 10 to 87 years) who visited the Seoul National University Dental Hospital from April 23, 2006 to December 31, 2008 and were diagnosed as osteomyelitis of the jaws through clinical, radiologic, and histopathologic examination. Each CT findings was investigated for frequency, correlation with age and gender. Of the 163 patients, 31 (19.0%) were affected on the maxilla, 135 (82.8%) were affected on the mandible, and 3 (1.8%) were affected on the both jaws simultaneously. The mean age of the patients who were affected on the maxilla was 61.0 years and that of the patients who were affected on the mandible was 56.2 years. On the maxilla, the most frequent site of disease was the posterior area (83.9%) and on the mandible, mandibular body (83.0%), followed by angle (48.1%), ramus (38.5%), condyle (13.3%), incisal area (9.6%), and coronoid process (3.0%). Among the 31 maxillary osteomyelitis, defect in the trabecular bone was observed in 28 (90.3%), osteosclerosis 20 (64.5%), defect in the cortical bone 27 (87.1%), sequestrum 17 (54.8%), and periosteal reaction 2 (6.5%). Among the 135 mandibular osteomyelitis, defect in the trabecular bone was observed in 100 (74.1%), osteosclerosis 104 (77.0%), defect in the cortical bone 116 (85.9%), sequestrum 36 (26.7%), and periosteal reaction 67 (49.6%). Of our cases, the maxillary osteomyelitis was visibly observed more frequently in females than males. The incidence is the highest in seventies (28.8%) and the lowest in teens (3.1%). The osteomyelitis of the jaws was observed more frequently in males than females before the age of 50, and observed more frequently in females after the age of 50. The most noticeable point was that the sequestrum was observed more often on maxillary osteomyelitis and the

  8. How to deal with bone exposure and osteomyelitis: an overview.

    2003-12-01

    The authors present an overview of the various techniques which can be used to achieve coverage of exposed bone, particularly in cases of bone exposure associated with an underlying fracture or osteomyelitis. Adequate debridement, possibly in several stages, is necessary in all cases to prepare the receptor site for the next step which is soft tissue coverage, achieved using various types of surgical procedures. Adequate reconstruction can be achieved with pedicled flaps in some cases but in cases with exposure of bone, free flaps usually represent a better option in cases where the condition of the patient is not a limiting factor. Thin fascio-cutaneous free flaps may be used in some cases with small and simple soft tissue loss, so as to minimise donor site mobidity. Free muscle flaps, such as from the latissimus dorsi, are preferable in cases with bone loss in order to fill any dead space; in cases with major bone loss, a free vascularised bone graft can be used, or composite grafts including bone, muscle and/or skin (fibula or crista iliaca flaps). Some reconstructions require a functional approach, such as over an exposed joint, or for the weight-bearing area of the foot or the soft tissues over the Achilles tendon. Survival of a free flap requires perfect, permeable microsutures; thrombosis of the anastomosis is a major complication which jeopardizes flap survival; close surveillance of the flap is required during the first few days, with hourly Doppler monitoring of the pedicle on the first day. The success rate can be as high as 90 to 100% in simple cases; failures may be related to surgical technique, inadequate choice of the flap, or specific features of the patient. In cases with an underlying bone infection, recurrence of infection occurs in 5 to 20% of cases; this requires additional treatment, possibly with repeat debridement, prolonged antibiotic therapy and sometimes a second free flap.

    Tuberculous meningitis is the severest and commonest form of central nervous system tuberculosis causing high mortality and morbidity. We aim to study the clinical, biochemical, and radiological characteristics of tuberculous meningitis in adult patients in Qatar and to calculate the incidence. A descriptive retrospective 7-year study was conducted at the Hamad General Hospital (the only tertiary referral center and sole health care provider for tuberculosis in Qatar) between the 1st of January 2006 and the 31st of December 2012, to describe the clinical presentation, diagnosis, treatment, outcome, and the incidence of adult tuberculous meningitis in Qatar. Tuberculous meningitis was diagnosed in 80 patients (65 male, 15 female), with a mean age of 30.3 ± 8.9. The majority of patients (76.3%) were from the Indian subcontinent. The commonest clinical features were fever (79%), headache (71%), and meningism (56%). Cerebrospinal fluid tuberculosis culture was positive in 44% of patients. Almost 39% of patients were in Stage I, 46% in Stage II and 15% in Stage III of the disease. The commonest neuroimaging features were leptomeningeal enhancement (34%) and hydrocephalus (33%). Cranial nerve palsy, limb weakness, and an elevated C-reactive protein were associated with a poorer outcome. Sixty eight percent had complete recovery, 10% had residual neurological sequelae without disability, 17% had disability, and 5% died. The average incidence of tuberculous meningitis over 7 years was 0.9 per 100,000 adult population. The characteristics of tuberculous meningitis were described in our population. Our data indicate that the incidence of tuberculosis meningitis in Qatar has increased. Tuberculous meningitis in Qatar is mainly an imported disease.

  10. Nodo-colonic fistula caused by intra-abdominal tuberculous lymphadenitis during treatment with anti-tuberculous medication: A case report

    Recently, the overall incidence of tuberculosis has decreased, but the incidence of an extrapulmonary manifestation in patients with tuberculosis has increased in the Republic of Korea. Although intestinal tuberculosis is not infrequent, a fistula caused by tuberculosis is a rare condition. A 23-year-old man presented with fever, diarrhea and right lower quadrant pain. A computed tomography (CT) scan revealed a lobulated, peripherally enhancing, low density mass in the mesentery. The patient underwent laparoscopic biopsy for necrotic lymph node, and intra-abdominal tuberculous lymphadenitis was diagnosed. Four months after initiating treatment with anti-tuberculous medication, the patient developed fever together with lower abdominal pain. A follow-up CT scan revealed a fistulous tract that had developed between the initially noted lymphadenopathy and the proximal ascending colon. Laparoscopic right hemicolectomy was performed as a curative treatment. This case suggests that a nodo-colonic fistula may occur as a paradoxical response in patients with intra-abdominal tuberculous lymphadenitis during treatment with anti-tuberculous medication.

    The prevalence of osteomyelitis in diabetic foot ulcers is unknown. Early diagnosis of this infection is critical, as prompt antibiotic treatment decreases the rate of amputation. The authors therefore assessed the prevalence of osteomyelitis in 35 diabetic patients with 41 foot ulcers. They compared results of roentgenograms, leukocyte scans with indium In 111 oxyquinoline, and bone scans with the diagnostic criterion standards of bone histologic and culture findings. Leukocyte scans were repeated at 2- to 3-week intervals during antibiotic treatment. Consecutive samples were obtained from 54 diabetic patients. Thirty-five patients with 41 foot ulcers were included. As determined by bone biopsy and culture, osteomyelitis was found to underlie 28 (68%) of 41 diabetic foot ulcers. Only nine (32%) of the 28 cases were diagnosed clinically by the referring physician. Underscoring the clinically silent nature of osteomyelitis in these ulcers, 19 (68%) of 28 occurred in outpatients, 19 (68%) of 28 occurred in ulcers not exposing bone, and 18 (64%) of 28 had no evidence of inflammation on physical examination. All patients with ulcers that exposed bone had osteomyelitis. Of the imaging tests, the leukocyte scan had the highest sensitivity, 89%. In patients with osteomyelitis, the leukocyte scan image intensity decreased by 16 to 34 days of antibiotic treatment and normalized by 36 to 54 days. The majority of diabetic foot ulcers have an underlying osteomyelitis that is clinically unsuspected. Leukocyte scans are highly sensitive for diagnosing osteomyelitis in diabetic foot ulcers and may be useful for monitoring the efficacy of antibiotic treatment. The recommend that diabetic patients with foot ulcers that expose bone should be treated for osteomyelitis

    To determine factors associated with the diagnosis of tuberculous uveitis and the response to anti-tuberculous treatment (ATT). A retrospective case study was performed at the University Medical Centre Utrecht between October 2007 and December 2009. Patients with possible tuberculous uveitis (TBU) were selected from all patients with an unexplained uveitis. Demographics, ethnicity, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), tuberculin skin test (TST), QuantiFERON (QFT) test, and ocular findings were evaluated. An interdisciplinary panel discussed if there was a presumed TBU and decided to start treatment. When there was a decrease in intraocular cell count and/or improvement in visual acuity after ATT, the confirmation of presumed TBU was made. Of 585 patients with unexplained uveitis, 66 (11.3%) fulfilled the definition of possible TBU. Ten (15.4%) patients were regarded as having presumed TBU and received ATT. All of them had latent tuberculosis (LTB). The ocular situation improved in seven patients (70%). A history of TB contact, abnormalities on chest radiology, and extraocular manifestations of TB were associated with a good response to ATT in the case of presumed tuberculous uveitis. Tuberculous uveitis remains difficult to diagnose. No clearly correlating factors that predicted the response to ATT, including ocular parameters, could be identified.

    Objective: To study the manifestations and its pathologic basis of pancreatic tubeiculosis and peripancreatic tuberculous lymphadenopathy. And evaluate the diagnostic values of CT and MRI. Methods: Two cases of pancreatic tuberculosis and eleven cases of peripancreatic tuberculous lymphadenopathy were collected. All cases were conformed by pathology or clinic. Plain scan and enhanced scan with spiral CT were performed in all cases. Plain scan and enhanced scan with MRI were performed in two cases. The CT and MRI features of 13 cases were analyzed retrospectively. Results: Pancreatic tuberculosis showed that the lesion was located mainly at the head of the pancreas and displayed on CT as a low-density mass with marginal or honeycomb enhancement. Peripancreatic tuberculous lymphadenopathy was seen in 11 cases, of which ring-like enhancement was seen in seven cases, calcifications in two cases and mixed in two cases. Splenic involvement was found in five cases. Conclusion: Pancreatic tuberculosis and peripancreatic tuberculous lymphadenopathy have the main features of low-density mass With marginal or honeycomb enhancement and ting-like enhancement in petipancreatic lymphadenopathy. CT and MRI are feasible methods in diagnosis of pancreatic tuberculosis and peripancreatic tuberculous lymphadenopathy. (authors)

    Seventy-seven diabetic patients with suspected osteomyelitis of the foot were evaluated by three-phase bone scintigraphy (TPBS), indium 111-labeled white blood cell scintigraphy (WBCS), roentgenography, or some combination thereof. Retrospective analysis after clinical and pathologic follow-up indicated that the sensitivity of TPBS alone in the diagnosis of osteomyelitis was 100%, with a specificity of only 38% and an accuracy of 63%; the sensitivity of WBCS alone was 100%, with a specificity of 78% and an accuracy of 87%; and the combination of TPBS and WBCS yielded a sensitivity of 100%, with a specificity of 79% and an accuracy of 87%. Roentgenography yielded a sensitivity of 69%, with a specificity of 82% and an accuracy of 76%. The results of this study demonstrate that WBCS is superior to TPBS in the diagnosis of osteomyelitis in the diabetic foot, and TPBS adds little when viewed in conjunction with WBCS. Based on our observations and because of the high prevalence of neuropathic joint disease and other causes of false-positive bone scans, we believe that WBCS alone is adequate for evaluation of suspected pedal osteomyelitis in diabetic patients, particularly when the suspected lesion is located in the tarsometatarsal region in contrast to the toe region (7% vs 44% specificity and 28% vs 69% accuracy, respectively, for TPBS in these two regions, compared with 100% vs 68% specificity and 100% vs 80% accuracy, respectively, for WBCS in the same two regions)

    The treatment of bone fractures is aimed at consolidating and returns of function as soon as possible and can be performed by different methods. Treatment with the plate in fractures of the femur in bridge aims not to address the location of fracture and stabilize it, maintaining the anatomical axis by the fixation of proximal and distal segments. Postoperative follow-up of the fracture is necessary to evaluate the irrigation of the bone structure and the effect of the method. The scintigraphy is a method capable of assessing the degree of bone remodeling and the presence or absence of local bone homeostasis. The objective of this report is to present the case of a rabbit, male, which was subjected to osteotomy and fixation of the femoral diaphysis by means of the plate in the bridge. After 10 days the animal was subjected to scintigraphic and radiographic evaluations. The animal came to death and an autopsy was performed on the same when it was observed macroscopy consistent with acute osteomyelitis due to contamination postoperative time. Radiographic evaluation in acute osteomyelitis is unclear. The methods assist in the scintigraphic diagnosis of osteomyelitis by allowing the detection of functional changes in this infectious process. The bone scintigraphy with diphosphonates labeled with technetium-99m shows increased bone turnover in the infected area and its high sensitivity, even in an early stage makes it the method of choice in the diagnosis of acute osteomyelitis in patients without prior bone disease and bone radiologically normal.

    Case report. To report 2 unusual cases of Pseudomonas aeruginosa epidural abscesses and cervical osteomyelitis after routine dental extractions and to review relevant literature. Pseudomonas aeruginosa is a rare cause of cervical osteomyelitis in patients after dental extractions. Only 1 prior case could be found in the literature. The cases of an 18-year-old male and a 23-year-old female are presented. PubMed was used to search for relevant literature. Our 2 patients presented with excruciating neck pain within 24 hours of routine dental extractions and, by imaging were found to have cervical epidural abscesses and osteomyelitis. Both patients were taken to the operating room for drainage and corpectomy and treated with prolonged courses of intravenous antibiotics. When seen in follow up 3 months later, neither patient demonstrated any neurologic sequelae. Pseudomonas aeruginosa epidural abscesses and osteomyelitis of the cervical spine have only rarely been reported in healthy patients after dental extractions. To our knowledge, the 2 patients reported here are only the second 2 such cases reported in the literature. Unfortunately, as in prior cases, these 2 patients had a significant delay in diagnosis. Therefore, a strong suspicion must be maintained for all patients presenting with neck pain after a recent dental extraction and appropriate imaging must be obtained urgently.

    2015-12-28

    BACKGROUND Sternoclavicular osteomyelitis is a rare disease, with less than 250 cases identified in the past 50 years. We present a rare case of sternoclavicular osteomyelitis in an immunosuppressed patient that developed from a conservatively treated dislocation. CASE REPORT A 62-year-old white man with a history of metastatic renal cell carcinoma presented to the emergency department (ED) with a dislocated left sternoclavicular joint. He was managed conservatively and subsequently discharged. However, over subsequent days he began to experience pain, fever, chills, and night sweats. He presented to the ED again and imaging revealed osteomyelitis. In the operating room, the wound was aggressively debrided and a wound vac (vacuum-assisted closure) was placed. He was diagnosed with sternoclavicular osteomyelitis and placed on a 6-week course of intravenous Nafcillin. CONCLUSIONS Chemotherapy patients who sustain joint trauma normally associated with a low risk of infection should be monitored thoroughly, and the option to discontinue immunosuppressive therapy should be considered if signs of infection develop.

    We studied the occurrence, magnitude, and kinetics of bacteremia and the resultant osteomyelitis and septic arthritis in an avian model of Staphylococcus aureus infection. Thirty-day-old male broiler chicks were inoculated i.v. with 10(5), 10(6), or 10(7) cfu of strain Duntravis, a beta-hemolytic, coagulase-producing, capsular type 8 isolate from the synovial fluid of a 2-year-old black boy. Bacteremia occurred in 80%, 90%, and 100% of animals inoculated with 10(5), 10(6), or 10(7) cfu, respectively. The magnitude of bacteremia in surviving, bacteremic animals increased for 96 hours after inoculation and then decreased after a plateau phase. Osteomyelitis and septic arthritis occurred only in chicks that were continuously bacteremic. The occurrence of osteomyelitis was uniform among continuously bacteremic animals and developed 1 to 23 hours after inoculation. Chickens are susceptible to systemic infections with S. aureus. Bacteremia, osteomyelitis, and septic arthritis may be induced in healthy chickens without prior manipulations that depress their resistance.

    Full Text Available Introduction: Coagulase-negative staphylococci are considered as microorganisms with little virulence and usually as contaminants. In order to establish the role of Staphylococcus epidermidis as a pathogen in diabetic foot osteomyelitis, in addition to the isolation of the sole bacterium from the bone it will be necessary to demonstrate the histopathological changes caused by the infection. Methods: A consecutive series of 222 diabetic patients with foot osteomyelitis treated surgically in the Diabetic Foot Unit at La Paloma Hospital (Las Palmas de Gran Canaria, Canary Islands, Spain between 1 October 2002 and 31 October 2008. From the entire series including 213 bone cultures with 241 isolated organisms, we have analyzed only the 139 cases where Staphylococci were found. We analyzed several variables between the two groups: Staphylococcus aureus versus Staphylococcus epidermidis. Results: Of the 134 patients included in this study, Staphlylococcus epidermidis was found as the sole bacterium isolated in 11 cases and accompanied by other bacteria in 12 cases. Staphlylococcus aureus was found as the sole bacterium isolated in 72 cases and accompanied by other bacteria in 39 cases. Histopathological changes were found in the cases of osteomyelitis where Staphylococcus epidermidis was the sole bacterium isolated. Acute osteomyelitis was found to a lesser extent when Staphylococcus epidermidis was the sole bacterium isolated but without significant differences with the cases where Staphylococcus aureus was the sole bacterium isolated. Conclusion: Staphylococcus epidermidis should be considered as a real pathogen, not only a contaminant, in diabetic patients with foot osteomyelitis when the bacterium is isolated from the bone. No differences in the outcomes of surgical treatment have been found with cases which Staphlylococcus aureus was isolated.

    Background. The epidemiology, pathogenesis, clinical manifestations, management, and outcome of Candida osteomyelitis are not well understood. Methods. Cases of Candida osteomyelitis from 1970 through 2011 were reviewed. Underlying conditions, microbiology, mechanisms of infection, clinical manifestations, antifungal therapy, and outcome were studied in 207 evaluable cases. Results. Median age was 30 years (range, ≤ 1 month to 88 years) with a >2:1 male:female ratio. Most patients (90%) were not neutropenic. Localizing pain, tenderness, and/or edema were present in 90% of patients. Mechanisms of bone infection followed a pattern of hematogenous dissemination (67%), direct inoculation (25%), and contiguous infection (9%). Coinciding with hematogenous infection, most patients had ≥2 infected bones. When analyzed by age, the most common distribution of infected sites for adults was vertebra (odds ratio [OR], 0.09; 95% confidence interval [CI], .04–.25), rib, and sternum; for pediatric patients (≤18 years) the pattern was femur (OR, 20.6; 95% CI, 8.4–48.1), humerus, then vertebra/ribs. Non-albicans Candida species caused 35% of cases. Bacteria were recovered concomitantly from 12% of cases, underscoring the need for biopsy and/or culture. Candida septic arthritis occurred concomitantly in 21%. Combined surgery and antifungal therapy were used in 48% of cases. The overall complete response rate of Candida osteomyelitis of 32% reflects the difficulty in treating this infection. Relapsed infection, possibly related to inadequate duration of therapy, occurred among 32% who ultimately achieved complete response. Conclusions. Candida osteomyelitis is being reported with increasing frequency. Localizing symptoms are usually present. Vertebrae are the most common sites in adults vs femora in children. Timely diagnosis of Candida osteomyelitis with extended courses of 6–12 months of antifungal therapy, and surgical intervention, when indicated, may improve

    CASE DESCRIPTION A 1-year-old reticulated python (Python reticulatus) was evaluated because of a 2-week history of wheezing and hissing. CLINICAL FINDINGS Rostral facial cellulitis and deep gingival pockets associated with missing rostral maxillary teeth were evident. Tissues of the nares were swollen, resulting in an audible wheeze during respiration. Multiple scars and superficial facial wounds attributed to biting by live prey were apparent. Radiographic examination revealed bilateral, focal, rostral maxillary osteomyelitis. TREATMENT AND OUTCOME Wound irrigation, antimicrobials, and anti-inflammatory drug treatment resulted in reduced cellulitis. A 3-week regimen that included empirical antimicrobial treatment and improved husbandry resulted in resolution of the respiratory sounds and partial healing of bite wounds, but radiographic evaluation revealed progressive maxillary osteomyelitis. Microbial culture of blood yielded scant gram-positive cocci and Bacillus spp, which were suspected sample contaminants. Bilateral partial maxillectomies were performed; microbial culture and histologic examination of resected bone confirmed osteomyelitis with gram-positive cocci. Treatment with trimethoprim-sulfamethoxazole was initiated on the basis of microbial susceptibility tests. Four months later, follow-up radiography revealed premaxillary osteomyelitis; surgery was declined, and treatment with trimethoprim-sulfamethoxazole was reinstituted. Eight months after surgery, the patient was reevaluated because of recurrent clinical signs; premaxillectomy was performed, and treatment with trimethoprim-sulfamethoxazole was prescribed on the basis of microbial culture of bone and microbial susceptibility testing. Resolution of osteomyelitis was confirmed by CT 11 months after the initial surgery. CONCLUSIONS AND CLINICAL RELEVANCE Focal maxillectomies and premaxillectomy were successfully performed in a large python. Surgical management and appropriate antimicrobial treatment

    A 39-year-old man, born in India but resident in the UK for 10 years, was travelling in America when he became feverish with an altered mentation. He reported a 10-day history of fever, photophobia, headache and fatigue. His medical history included hypothyroidism and migraine. He was a non-smoker, did not consume alcohol and denied a history of drug use. He was transferred to the emergency department. Laboratory investigations confirmed hyponatraemia (sodium 128 mmol/L). A chest radiograph confirmed no focal consolidation. Further investigation with a CT brain was unremarkable. A lumbar puncture was suggestive of viral meningitis, with a raised white cell count, lymphocytosis, high protein and low glucose. His PCR was negative for enterovirus and herpes simplex virus. Further investigation with a CT thorax, abdomen and pelvis demonstrated bilateral upper-lobe infiltrations. A bronchoalveolar lavage was negative for acid alcohol fast bacilli (AAFB). A diagnosis of tuberculous meningitis was rendered following a repeat lumbar puncture. Gram stain revealed AAFB and PCR was also positive. He started antitubercular treatment and corticosteroids. A repeat CT brain demonstrated ventriculomegaly, suggestive of hydrocephalus and an MRI head revealed likely communicating hydrocephalus with basilar enhancement. He was repatriated to the UK. Eleven days post transfer, he became acutely confused and required external ventricular drain insertion. After surgical management of his hydrocephalus, there was no further neurological deterioration. He remains committed to his neurorehabilitation. 2016 BMJ Publishing Group Ltd.

    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.

    Tuberculous spondylodiscitis (TS) is a rare but serious clinical condition which may lead to severe deformity and early or late neurological complications. To discuss certain aspects of the approach to TSs, focusing upon epidemiology, diagnosis, and treatment outcome. For the purpose of this review, a literature search was performed using the Pubmed database through to 19th October 2011 to identify studies published in the last 20 years, concerned in epidemiological, clinical, diagnostic, and therapeutical aspects of TS in adults. Only studies drafted in English language and reporting case series of more than 20 patients have been included. TS has been reported to accounts for 1-5% of all TB cases, and for about 50% of the cases of articulo-skeletal TB infections. Despite the actual availability of more effective diagnostic tools, early recognition of TS remains difficult and a high index of suspicion is needed due to the chronic nature of the disease and its insidious and variable clinical presentation. A prompt diagnosis is required to improve long term outcome, and a microbiological confirmation is recommended to enable appropriate choice of anti-mycobacterial agents. Surgery has an important role in alleviating pain, correcting deformities and neurological impairment, and restoring function. Further studies are required to assess the appropriate duration of anti-microbial treatment, also in regarding of a combined surgical approach.

    Objective. To investigate the relationship among angiogenic cytokines, inflammatory markers, and fibrinolytic activity in tuberculous pleural effusion (TBPE) and their clinical importance. Methods. Forty-two patients diagnosed with TBPE were studied. Based on chest ultrasonography, there were 26 loculated and 16 nonloculated TBPE patients. The effusion size radiological scores and effusion vascular endothelial growth factor (VEGF), interleukin- (IL-) 8, plasminogen activator inhibitor type-1 (PAI-1), and tissue type plasminogen activator (tPA) were measured. Treatment outcome and pleural fibrosis, defined as radiological residual pleural thickening (RPT), were assessed at 6-month follow-up. Results. The effusion size and effusion lactate dehydrogenase (LDH), VEGF, IL-8, PAI-1, and PAI-1/tPA ratio were significantly higher, while effusion glucose, pH value, and tPA were significantly lower, in loculated than in nonloculated TBPE. VEGF and IL-8 correlated positively with LDH and PAI-1/tPA ratio and negatively with tPA in both loculated and nonloculated TBPE. Patients with higher VEGF or greater effusion size were prone to develop RPT (n = 14; VEGF, odds ratio 1.28, P = 0.01; effusion size, odds ratio 1.01, P = 0.02), and VEGF was an independent predictor of RPT in TBPE (receiver operating characteristic curve AUC = 0.985, P Effusion VEGF correlates with pleural inflammation and fibrosis and may be targeted for adjunct therapy for TBPE.

    2011-07-01

    Full Text Available Eosinophilic peritonitis is an uncommon clinical entity with diagnostic considerations separate from those of tuberculous peritonitis. We report a patient on continuous ambulatory peritoneal dialysis (CAPD with eosinophilic peritonitis resulting from tuberculous peritonitis. Acid-fast stain and mycobacterial culture of peritoneal dialysis effluent were both negative result. In the peritoneal dialysis effluent and blood samples, Mycobacterium tuberculosis was detected by polymerase chain reaction analyses. The initiation of antituberculous therapy resulted in resolution of the eosionphilia in the dialysis effluent. After 14 days of antituberculous therapy, the polymerase chain reaction analyses of tuberculosis were negative for both the blood and peritoneal dialysis effluents. Evaluation of tuberculosis infection is necessary if the CAPD-related peritonitis presents with an unusual and unexplained clinical course. Polymerase chain reaction can play an important role in the diagnosis of tuberculous peritonitis in patients undergoing CAPD.

    Tuberculous meningitis, a serious disease with high mortality and morbidity, remains frequent in countries with endemic tuberculosis. Its non-specific presentation often delays the introduction of appropriate treatment. Its definitive diagnosis requires isolation of Mycobacterium tuberculosis from cerebrospinal fluid, although this test may be negative without conclusively ruling out this diagnosis. A presumptive diagnosis should be reached as soon as possible through a body of clinical evidence, including the lumbar puncture findings. Brain computed tomography (CT) with and without contrast medium injection is helpful for the diagnosis of tuberculous meningitis and its complications. We discuss the features of CT and their value in relation to a case of tuberculous meningitis in Djibouti, as well as the role of CT in managing this disease.

    The pattern of the earliest cell divisions in a vertebrate embryo lays the groundwork for later developmental events such as gastrulation, organogenesis, and overall body plan establishment. Understanding these early cleavage patterns and the mechanisms that create them is thus crucial for the study of vertebrate development. This chapter describes the early cleavage stages for species representing ray-finned fish, amphibians, birds, reptiles, mammals, and proto-vertebrate ascidians and summarizes current understanding of the mechanisms that govern these patterns. The nearly universal influence of cell shape on orientation and positioning of spindles and cleavage furrows and the mechanisms that mediate this influence are discussed. We discuss in particular models of aster and spindle centering and orientation in large embryonic blastomeres that rely on asymmetric internal pulling forces generated by the cleavage furrow for the previous cell cycle. Also explored are mechanisms that integrate cell division given the limited supply of cellular building blocks in the egg and several-fold changes of cell size during early development, as well as cytoskeletal specializations specific to early blastomeres including processes leading to blastomere cohesion. Finally, we discuss evolutionary conclusions beginning to emerge from the contemporary analysis of the phylogenetic distributions of cleavage patterns. In sum, this chapter seeks to summarize our current understanding of vertebrate early embryonic cleavage patterns and their control and evolution.

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

    This paper reports on a study involving twenty-four patients with soft-tissue infections or wounds and radiographic abnormalities in contiguous bones possibly representing osteomyelitis who underwent three-phase T c -99 m methylene diphosphonate (MDP) bone scanning, followed by In-111 leukocyte scintigraphy (22 patients) and bone biopsy (21 patients). Chronic osteomyelitis was confirmed in 12 patients by means of biopsy cultures and in one by means of histologic findings following amputation. Four patterns of leukocyte uptake in bone were identified: definitely increased, possibly increased, normal, and decreased. The prevalence of osteomyelitis for these four leukocyte scan patterns was as follows: 89% (eight of nine patients), 40% (two of five), 20% (one of five), and 67% (two of three), respectively. A definite increase in bone uptake of In-111-labeled leukocytes usually reflects osteomyelitis, but bone biopsy may be necessary to establish the diagnosis when other scan patterns are present

    Formation of tuberculoma is a rare response of neurotuberculosis in patients regularly and adequately treated with anti-tuberculous drugs. We report a 13-year-old girl with two tuberculomas which formed in the dorsal part of the medulla oblongata during chemotherapy for tuberculous meningitis. The tuberculomas were both removed via a suboccipital midline approach and were demonstrated by pathological findings but the girl died of cardiac arrest that was thought to be caused by postoperative medulla oblongata oedema. In combination with a literature review, we discuss the clinical features and treatment options of brainstem tuberculomas.

    Full Text Available Tuberculous myositis, which mimics rheumatic symptoms, is an extremely rare disease. Clinical ambiguity easily leads to misdiagnosis and delayed initial treatment. We present the case of a 55-year-old man who had primary Sjögren's syndrome and active cutaneous vasculitis treated with steroid and immunosuppressive drugs. He presented with a swollen, painful, hot left thigh. Although anti-tuberculosis medications were administered soon after a positive acid-fast stain of incisional muscular tissue, he died of rapidly progressive tuberculous myositis and multiorgan failure following 18 days of hospitalization. This case is presented to increase the awareness of this rare entity in clinical practice.

Average CD4 count in group 1 made 189 cells/mcl. The following parameters were compared in those groups: clinical and X-ray manifestations, microbiological, cytologic and biochemical rates in blood and effluent. 77 patients with isolated pleurisy (of them 33 HIV positive had video-assisted thoracoscopy with biopsy for diagnostic purposes. The data of histological examination of pleura, obtained through video-assisted thoracoscopy and autopsy have been presented.Results: tuberculous pleurisy with concurrent HIV infection is characterized by frequent occurrence of hemorrhagic effusion, scarce cellular sediment of effluent, expressed reduction of glucose level and increase of thymol test rates in effluent. Regardless of HIV status the frequency of tuberculous mycobacteria detection through microscopy and culture is low and does not exceed 10%. Histological testing of specimens obtained through video-assisted thoracoscopy allowed proving tuberculosis in all patients thus differentiating tuberculous changes from metastases. Thus video-assisted thoracoscopy can be recommended for diagnostics of difficult cases of tuberculous pleurisy regardless of HIV status.From morphological point of view tuberculous pleurisy was characterized by specific granulomas which were presented by lymphoid and epithelioid cells with Pirogov-Langhans cells with minor caseous necrosis in the center (9.1% or its complete absence (90.9%.

    Pleural effusion is a common occurrence in patients with late-stage chronic kidney disease (CKD). In developing countries, many effusions remain undiagnosed after pleural fluid analysis (PFA) and patients are empirically treated with antitubercular therapy. The aim of this study was to evaluate the role of adenosine deaminase (ADA), nucleic acid amplification tests (NAAT) and medical thoracoscopy in distinguishing tubercular and non-tubercular aetiologies in exudative pleural effusions complicating CKD. Consecutive stage 4 and 5 CKD patients with pleural effusions underwent PFA including ADA and PCR [65 kDa gene; multiplex (IS6110, protein antigen b, MPB64)]. Patients with exudative pleural effusion undiagnosed after PFA underwent medical thoracoscopy. All 107 patients underwent thoracocentesis with 45 and 62 patients diagnosed as transudative and exudative pleural effusions, respectively. Twenty six of the 62 patients underwent medical thoracoscopy. Tuberculous pleurisy was diagnosed in six while uraemic pleuritis was diagnosed in 20 subjects. The sensitivity and specificity of pleural fluid ADA, 65 kDa gene PCR, and multiplex PCR were 66.7 and 90 per cent, 100 and 50 per cent, and 100 and 100 per cent, respectively. Thoracoscopy was associated with five complications in three patients. Uraemia remains the most common cause of pleural effusion in CKD even in high TB prevalence country. Multiplex PCR and thoracoscopy are useful investigations in the diagnostic work-up of pleural effusions complicating CKD while the sensitivity and/or specificity of ADA and 65 kDa gene PCR is poor.

  15. Evolution of endothelin receptors in vertebrates.

    Endothelin receptors are G protein coupled receptors (GPCRs) of the β-group of rhodopsin receptors that bind to endothelin ligands, which are 21 amino acid long peptides derived from longer prepro-endothelin precursors. The most basal Ednr-like GPCR is found outside vertebrates in the cephalochordate amphioxus, but endothelin ligands are only present among vertebrates, including the lineages of jawless vertebrates (lampreys and hagfishes), cartilaginous vertebrates (sharks, rays, and chimaeras), and bony vertebrates (ray-finned fishes and lobe-finned vertebrates including tetrapods). A bona fide endothelin system is thus a vertebrate-specific innovation with important roles for regulating the cardiovascular system, renal and pulmonary processes, as well as for the development of the vertebrate-specific neural crest cell population and its derivatives. Expectedly, dysregulation of endothelin receptors and the endothelin system leads to a multitude of human diseases. Despite the importance of different types of endothelin receptors for vertebrate development and physiology, current knowledge on endothelin ligand-receptor interactions, on the expression of endothelin receptors and their ligands, and on the functional roles of the endothelin system for embryonic development and in adult vertebrates is very much biased towards amniote vertebrates. Recent analyses from a variety of vertebrate lineages, however, have shown that the endothelin system in lineages such as teleost fish and lampreys is more diverse and is divergent from the mammalian endothelin system. This diversity is mainly based on differential evolution of numerous endothelin system components among vertebrate lineages generated by two rounds of whole genome duplication (three in teleosts) during vertebrate evolution. Here we review current understanding of the evolutionary history of the endothelin receptor family in vertebrates supplemented with surveys on the endothelin receptor gene complement of

Furthermore, we found that vertebrates' conserved mid-embryonic developmental programmes are intensively recruited to other developmental processes, and the degree of the recruitment positively correlates with their evolutionary conservation and essentiality...... for normal development. Thus, we propose that the intensively recruited genetic system during vertebrates' organogenesis period imposed constraints on its diversification through pleiotropic constraints, which ultimately led to the common anatomical pattern observed in vertebrates....

    Staphylococcus aureus osteomyelitis is a common and debilitating invasive infection of bone. Treatment of osteomyelitis is confounded by widespread antimicrobial resistance and the propensity of bacteria to trigger pathological changes in bone remodeling that limit antimicrobial penetration to the infectious focus. Adjunctive therapies that limit pathogen-induced bone destruction could therefore limit morbidity and enhance traditional antimicrobial therapies. In this study, we evaluate the efficacy of the U.S. Food and Drug Administration-approved, nonsteroidal anti-inflammatory (NSAID) compound diflunisal in limiting S. aureus cytotoxicity toward skeletal cells and in preventing bone destruction during staphylococcal osteomyelitis. Diflunisal is known to inhibit S. aureus virulence factor production by the accessory gene regulator (agr) locus, and we have previously demonstrated that the Agr system plays a substantial role in pathological bone remodeling during staphylococcal osteomyelitis. Consistent with these observations, we find that diflunisal potently inhibits osteoblast cytotoxicity caused by S. aureus secreted toxins independently of effects on bacterial growth. Compared to commonly used NSAIDs, diflunisal is uniquely potent in the inhibition of skeletal cell death in vitro Moreover, local delivery of diflunisal by means of a drug-eluting, bioresorbable foam significantly limits bone destruction during S. aureus osteomyelitis in vivo Collectively, these data demonstrate that diflunisal potently inhibits skeletal cell death and bone destruction associated with S. aureus infection and may therefore be a useful adjunctive therapy for osteomyelitis.

  19. Soft tissue reconstruction for calcaneal fractures or osteomyelitis.

    2001-01-01

    A systematic approach of the surgical management of a calcaneal fracture can minimize the potential of soft tissue complications. When reducing a closed calcaneal fracture, the incision used affects the postoperative complications. The L-shaped incision with the horizontal limb lying on the lateral glabrous junction ensures maximum blood flow to either side of the incision. Whether or not the wound can be closed primarily depends on the preexisting edema, the lost calcaneal height, and the delay between the fracture and reduction (Fig. 20). The wrinkle test is a good indicator that the incision can be closed primarily if the amount of height restored is minimal. If the edema is too great, steps should be taken to reduce it sufficiently to allow successful wound closure. If the wound, after reduction, is too wide to allow primary closure, an ADM flap laterally or an AHM flap medially should be used. For larger defects, a free flap should be considered. The three important steps to reconstruction of soft tissue defects around the calcaneus include good blood supply, a infection-free wound, and the simplest soft tissue reconstructive option that covers the wound successfully. Adequate blood supply can be determined by the use of Doppler. If the supply is inadequate, revascularization is necessary before proceeding. Achieving a clean wound requires aggressive debridement, intravenous antibiotics, and good wound care. Adjuncts that can help in achieving a clean wound include topical antibiotics (silver sulfadiazine), the VAC, and hyperbaric oxygen. Osteomyelitis has to be treated aggressively. Any suspicious bone has to be removed. Only clean, healthy, bleeding bone is left behind. Antibiotic beads can be useful when there is doubt as to whether the cancellous bone is infection-free. The beads are not a substitute for good debridement, however. Soft tissue reconstruction ranges from delayed primary closure to the use of microsurgical free flaps (Fig. 21). When bone or

    Implant related infection is one of the most feared and devastating complication associated with the use of orthopaedic implant devices. Development of anti-infective surfaces is the main strategy to prevent implant contamination, biofilm formation and implant related osteomyelitis. A second concern in orthopaedics is insufficient osseointegration of uncemented implant devices. Recently, we reported on a macroporous titanium-oxide surface (bioactive TiOB) which increases osseointegration and implant fixation. To combine enhanced osseointegration and antibacterial function, the TiOB surfaces were, in addition, modified with a gentamicin coating. A rat osteomyelitis model with bilateral placement of titanium alloy implants was employed to analyse the prophylactic effect of gentamicin-sodiumdodecylsulfate (SDS) and gentamicin-tannic acid coatings in vivo. 20 rats were randomly assigned to four groups: (A) titanium alloy; PBS inoculum (negative control), (B) titanium alloy, Staphylococcus aureus inoculum (positive control), (C) bioactive TiOB with gentamicin-SDS and (D) bioactive TiOB plus gentamicin-tannic acid coating. Contamination of implants, bacterial load of bone powder and radiographic as well as histological signs of implant-related osteomyelitis were evaluated after four weeks. Gentamicin-SDS coating prevented implant contamination in 10 of 10 tibiae and gentamicin-tannic acid coating in 9 of 10 tibiae (infection prophylaxis rate 100% and 90% of cases, respectively). In Group (D) one implant showed colonisation of bacteria (swab of entry point and roll-out test positive for S. aureus). The interobserver reliability showed no difference in the histologic and radiographic osteomyelitis scores. In both gentamicin coated groups, a significant reduction of the histological osteomyelitis score (geometric mean values: C = 0.111 ± 0.023; D = 0.056 ± 0.006) compared to the positive control group (B: 0.244 ± 0.015; p < 0.05) was observed.

    Objective In the present study, we aimed to assess whether gelatin/β-tricalcium phosphate (β-TCP) composite porous scaffolds could be used as a local controlled release system for vancomycin. We also investigated the efficiency of the scaffolds in eliminating infections and repairing osteomyelitis defects in rabbits. Methods The gelatin scaffolds containing differing amounts of of β-TCP (0%, 10%, 30% and 50%) were prepared for controlled release of vancomycin and were labelled G-TCP0, G-TCP1, G-TCP3 and G-TCP5, respectively. The Kirby-Bauer method was used to examine the release profile. Chronic osteomyelitis models of rabbits were established. After thorough debridement, the osteomyelitis defects were implanted with the scaffolds. Radiographs and histological examinations were carried out to investigate the efficiency of eliminating infections and repairing bone defects. Results The prepared gelatin/β-TCP scaffolds exhibited a homogeneously interconnected 3D porous structure. The G-TCP0 scaffold exhibited the longest duration of vancomycin release with a release duration of eight weeks. With the increase of β-TCP contents, the release duration of the β-TCP-containing composite scaffolds was decreased. The complete release of vancomycin from the G-TCP5 scaffold was achieved within three weeks. In the treatment of osteomyelitis defects in rabbits, the G-TCP3 scaffold showed the most efficacious performance in eliminating infections and repairing bone defects. Conclusions The composite scaffolds could achieve local therapeutic drug levels over an extended duration. The G-TCP3 scaffold possessed the optimal porosity, interconnection and controlled release performance. Therefore, this scaffold could potentially be used in the treatment of chronic osteomyelitis defects. Cite this article: J. Zhou, X. G. Zhou, J. W. Wang, H. Zhou, J. Dong.

    To analyze the clinical and radiological characteristics and features of pleural fluid (PF) in patients with tuberculous pleural effusion (TPE). Retrospective analysis of TPEs treated in our clinic over the last 23years. We included 320 patients with TPE (70% men; median age 33years). Mycobacterium tuberculosis was identified in the sputum or PF of 36% of the patients by microscopic examination, solid and liquid media cultures, or nucleic acid amplification tests. The greatest percentage of positive microbiological findings were associated with human immunodeficiency virus (HIV) co-infection (OR: 3.27), and with the presence in PF of proteins 60% (OR: 3.23), and glucose Pleural adenosine deaminase <35U/L was associated with TPEs that occupied less than half of the hemithorax (OR: 6.36) and with PF lactate dehydrogenase levels <500U/L (OR: 8.09). Radiological pulmonary opacities (30%) were more common in TPE occupying less than half of the hemithorax (OR: 2.73), in bilateral TPE (OR: 4.48), and in older patients (OR: 1.02). Factors predicting mortality were: HIV co-infection (OR: 24), proteins in PF <5g/dL (OR: 10), and greater age (OR: 1.05). Patients with TPE and HIV co-infection and those with lower concentrations of proteins in PF had higher rates of positive microbiological results and death. Moreover, older patients had more pulmonary opacities and a higher incidence of death. Copyright © 2018 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Tuberculous meningitis (TBM is one of the most severe extrapulmonary manifestations of tuberculosis, with a high morbidity and mortality. Characteristic pathological features of TBM are Rich foci, i.e. brain- and spinal-cord-specific granulomas formed after hematogenous spread of pulmonary tuberculosis. Little is known about the early pathogenesis of TBM and the role of Rich foci. We have adapted the zebrafish model of Mycobacterium marinum infection (zebrafish–M. marinum model to study TBM. First, we analyzed whether TBM occurs in adult zebrafish and showed that intraperitoneal infection resulted in granuloma formation in the meninges in 20% of the cases, with occasional brain parenchyma involvement. In zebrafish embryos, bacterial infiltration and clustering of infected phagocytes was observed after infection at three different inoculation sites: parenchyma, hindbrain ventricle and caudal vein. Infection via the bloodstream resulted in the formation of early granulomas in brain tissue in 70% of the cases. In these zebrafish embryos, infiltrates were located in the proximity of blood vessels. Interestingly, no differences were observed when embryos were infected before or after early formation of the blood-brain barrier (BBB, indicating that bacteria are able to cross this barrier with relatively high efficiency. In agreement with this observation, infected zebrafish larvae also showed infiltration of the brain tissue. Upon infection of embryos with an M. marinum ESX-1 mutant, only small clusters and scattered isolated phagocytes with high bacterial loads were present in the brain tissue. In conclusion, our adapted zebrafish–M. marinum infection model for studying granuloma formation in the brain will allow for the detailed analysis of both bacterial and host factors involved in TBM. It will help solve longstanding questions on the role of Rich foci and potentially contribute to the development of better diagnostic tools and therapeutics.

    Full Text Available Context: Prevalence of tuberculous pleural effusion is very high in the Asian subcontinent but very few studies have come up from this part of the world about the course of recovery of pulmonary functions after institution of anti-tubercular therapy (ATT and thoracentesis. Aims: To study initial lung function impairment, changes over time after institution of ATT and thoracentesis and residual abnormalities left at the end of six months of treatment. Settings and Design: Randomized open level interventional study over two years in 52 patients at a tertiary level teaching hospital. Methods: The study population was divided into two equal groups, A (therapeutic thoracentesis and B (diagnostic thoracentesis. Spirometry, chest radiograph and ultrasonography of thorax were done initially and at each follow-up visit up to six months. Statistical analysis was done (P value < 0.05 considered significant. Results: Both groups were comparable initially. After six months none in group A and five patients in group B had minimal pleural effusion. During follow up, mean percentage predicted of FEV1 and FVC increased more in A than in B and the differences were statistically significant (P < 0.05. Pleural thickening, initially absent in both groups, was found to be more in B as compared to A at subsequent follow-up visits and this was statistically significant (P < 0.05. Conclusions: Thoracentesis should be considered in addition to anti-TB treatment, especially in large effusions, in order to relieve dyspnea, avoid possibility of residual pleural thickening and risk of developing restrictive functional impairment.

    2017-08-21

    The first major developmental transition in vertebrate embryos is the maternal-to-zygotic transition (MZT) when maternal mRNAs are degraded and zygotic transcription begins. During the MZT, the embryo takes charge of gene expression to control cell differentiation and further development. This spectacular organismal transition requires nuclear reprogramming and the initiation of RNAPII at thousands of promoters. Zygotic genome activation (ZGA) is mechanistically coordinated with other embryonic events, including changes in the cell cycle, chromatin state, and nuclear-to-cytoplasmic component ratios. Here, we review progress in understanding vertebrate ZGA dynamics in frogs, fish, mice, and humans to explore differences and emphasize common features. Copyright © 2017 Elsevier Inc.

  6. The origin of vertebrate limbs.

    The earliest tetrapod limbs are polydactylous, morphologically varied and do not conform to an archetypal pattern. These discoveries, combined with the unravelling of limb developmental morphogenetic and regulatory mechanisms, have prompted a re-examination of vertebrate limb evolution. The rich fossil record of vertebrate fins/limbs, although restricted to skeletal tissues, exceeds the morphological diversity of the extant biota, and a systematic approach to limb evolution produces an informative picture of evolutionary change. A composite framework of several phylogenetic hypotheses is presented incorporating living and fossil taxa, including the first report of an acanthodian metapterygium and a new reconstruction of the axial skeleton and caudal fin of Acanthostega gunnari. Although significant nodes in vertebrate phylogeny remain poorly resolved, clear patterns of morphogenetic evolution emerge: median fin origination and elaboration initially precedes that of paired fins; pectoral fins initially precede pelvic fin development; evolving patterns of fin distribution, skeletal tissue diversity and structural complexity become decoupled with increased taxonomic divergence. Transformational sequences apparent from the fish-tetrapod transition are reiterated among extant lungfishes, indicating further directions for comparative experimental research. The evolutionary diversification of vertebrate fin and limb patterns challenges a simple linkage between Hox gene conservation, expression and morphology. A phylogenetic framework is necessary in order to distinguish shared from derived characters in experimental model regulatory systems. Hox and related genomic evolution may include convergent patterns underlying functional and morphological diversification. Brachydanio is suggested as an example where tail-drive patterning demands may have converged with the regulation of highly differentiated limbs in tetrapods.

    Here we review mechanisms and factors influencing contaminant exposure among terrestrial vertebrate wildlife. There exists a complex mixture of biotic and abiotic factors that dictate potential for contaminant exposure among terrestrial and semi-terrestrial vertebrates. Chemical fate and transport in the environment determine contaminant bioaccessibility. Species-specific natural history characteristics and behavioral traits then play significant roles in the likelihood that exposure pathways, from source to receptor, are complete. Detailed knowledge of natural history traits of receptors considered in conjunction with the knowledge of contaminant behavior and distribution on a site are critical when assessing and quantifying exposure. We review limitations in our understanding of elements of exposure and the unique aspects of exposure associated with terrestrial and semi-terrestrial taxa. We provide insight on taxa-specific traits that contribute, or limit exposure to, transport phenomenon that influence exposure throughout terrestrial systems, novel contaminants, bioavailability, exposure data analysis, and uncertainty associated with exposure in wildlife risk assessments. Lastly, we identify areas related to exposure among terrestrial and semi-terrestrial organisms that warrant additional research. - Both biotic and abiotic factors determine chemical exposure for terrestrial vertebrates

    99mTc-labeled antigranulocyte monoclonal antibody Fab' fragments have shown a high sensitivity and specificity for detecting osteomyelitis in prospective studies. We retrospectively evaluated the use of LeukoScan {sup trademark} (Immunomedics, Morris Plains, N.J.) in clinical routine for the detection of bone and soft tissue infections and we want to present the results of our findings as well as some of the more interesting cases in this occasion. Imaging infection can be performed fast and easy with {sup 99m}Tc-Fab' fragments due to a fast targeting of infection and good background clearance, which increases in imaging quality. The application of {sup 99m}Tc-Fab' fragments gives good results in patients with bone and soft tissue infections of peripheral bones, as well as in patients with infected prostheses and infected arthritis. The use of {sup 99m}Tc-Fab' fragments should not be limited to these patients only, since good results can also be achieved in patients with infections of vascular grafts, of appendicitis and of endocarditis as well. A higher number of false-negative results has to be expected in case of subacute/chronic infections instead. Independent of the grade of infection acute/subacute infections of the spine always show 'cold lesions'. If cold lesions are used as guide for diagnosing a pathologic finding, an increase in sensitivity together with a decrease in specificity can be achieved. (orig.)

    The fossa navicularis is a notch-like bone defect in the basiocciput that has been hitherto considered as an anatomical variant of the clivus and not previously described as a potential source of clival or skull base pathology. We report the imaging findings in a 5-year-old child who presented acutely with a retropharyngeal abscess and osteomyelitis of the clivus. Imaging after treatment revealed a ''notch-like'' defect in the anterior clivus consistent with a fossa navicularis. Based on these appearances, we postulate that the lymphoid tissue of the pharyngeal tonsil residing in the fossa navicularis served as a route through which infection spread and subsequently developed into clival osteomyelitis, which is a rare diagnosis. This case is unique, and we believe that the presence of this variant in young children may be important and is not merely an anatomical curiosity. (orig.)

    Radiation therapy for breast cancer has improved survival rates; however, a consequence of this is treatment-induced complications in longer-living patients. Decades after chest wall irradiation, very late onset radiation-induced osteomyelitis can develop, caused by osteoradionecrosis. This may lead to the development of small, but very refractory, skin ulcers. Many reports recommend well-vascularized tissue coverage after appropriate debridement for irradiation ulcers; however, when the ulcers are of very late onset, this sometimes causes recurrence of ulceration in non-muscle-covered areas after flap transfer. Thus, for very late onset cases, we propose treatment with an absolute muscle flap to cover both the obviously infected focus and the surrounding irradiated area. A muscle flap consisting of the entire latissimus dorsi, the shape of which is very large in the horizontal direction, satisfies this requirement. Latissimus dorsi muscle coverage for the treatment of very late onset osteomyelitis should be reappraised. (author)

    Full Text Available Mycobacterium marinum (M. marinum is a ubiquitous waterborne organism that grows optimally at temperatures around 30°C. It is a nontuberculous Mycobacterium found in nonchlorinated water with worldwide prevalence. It is the most common atypical Mycobacterium that causes opportunistic infection in humans. M. marinum can cause superficial infections and localized invasive infections in humans, with the hands being the sites most frequently affected. It can cause skin lesions, which are either single, papulonodular lesions, confined to an extremity, or may resemble cutaneous sporotrichosis. This infection can also cause deeper infections including tenosynovitis, bursitis, arthritis, and osteomyelitis. Disseminated infections and visceral involvements have been reported in immunocompromised patients. We here report a case of severe deep soft tissue infection with necrotizing fasciitis and osteomyelitis of the left upper extremity (LUE caused by M. marinum in an immunocompromised patient.

    Full Text Available We are reporting a case of nonabsorbable suture-induced osteomyelitis in patient who had an open rotator cuff repair with nonabsorbable Ethibond anchor suture. Patient in this case presented with very subtle clinical features of osteomyelitis of the left proximal humerus 15 years after initial rotator cuff repair surgery. Literature had shown that deep infection following rotator cuff repairs, although rare, can be easily missed and can cause severe complications. Absorbable suture had been demonstrated to be more superior, in terms of rate of deep infection, as compared to nonabsorbable suture when used in rotator cuff repair surgery. Both absorbable and nonabsorbable suture had been demonstrated to have similar mechanical properties by several different studies. The case demonstrated that initial presentation of deep infection can be subtle and easily missed by clinicians and leads to further complications.

    2016-04-01

    Full Text Available Osteopetrosis is characterized by a considerable increase in bone density resulting in defective remodeling, caused by failure in the normal function of osteoclasts, and varies in severity. It is usually subdivided into three types: benign autosomal dominant osteopetrosis; intermediate autosomal recessive osteopetrosis; and malignant autosomal recessive infantile osteopetrosis, considered the most serious type. The authors describe a case of chronic osteomyelitis in the maxilla of a 6-year-old patient with Malignant Infantile Osteopetrosis. The treatment plan included pre-maxilla sequestrectomy and extraction of erupted upper teeth. No surgical procedure was shown to be the best to prevent the progression of oral infection. Taking into account the patient's general condition, if the patient develops severe symptomatic and refractory osteomyelitis surgery should be considered. The patient and his family are aware of the risks and benefits of surgery and its possible complications.

    Full Text Available Goal of the study: to study specific features of detection, diagnostics, clinical, morphological manifestations and treatment efficiency of tuberculous exudative pleurisy in those with alcohol addiction.Materials and methods. 62 medical cases of those suffering from exudative tuberculous pleurisy were retrospectively studied, in whom alcohol addiction was diagnosed basing on the patient's history and examination by the substance abuse doctor. Tuberculous pleurisy was verified in 80.65% of cases.  Results: Alcohol addiction was diagnosed in 15% of those suffering from tuberculous pleurisy. Among patients with alcohol addiction 47% were 30 years old and older, and they were single, 11% lived alone, 76% were the unemployed but within employable age, 27% had previous convictions, and 10% were homeless. More than 27% of patients had not have fluorography screening for 2 years and more. In 53% of cases pleurisy was combined with concurrent pulmonary lesions and in 27% of cases respiratory lesions were bilateral. Destruction of lung tissue was observed in 42% of cases, and in 35.5% tuberculosis mycobacteria were found in sputum. Caseous necrosis was found in 7.5% of cases, epithelioid giant-cell granulomas were found in 64% of cases, and caseous necrosis in granulemas was found in 44% of cases when examining the needle biopsy specimens. Poor treatment adherence and low treatment efficiency had been observed among those patients.

    Tuberculous pleurisy is traditionally indicated by extreme lymphocytosis in pleural fluid and low yield of effusion culture. However, there is considerable inconsistency among previous study results. In addition, these data should be updated due to early effusion studies and advances in culture methods. From January 2004 to June 2009, patients with tuberculous pleurisy were retrospectively identified from the mycobacteriology laboratories and the pathology and tuberculosis registration databases of two hospitals in Taiwan where tuberculosis is endemic. Pleural fluid characteristics and yields of mycobacterial cultures using liquid media were evaluated. A total of 382 patients with tuberculous pleurisy were identified. The median lymphocyte percentage of total cells in pleural fluids was 84% (IQR 64-95%) and 17% of cases had a lymphocyte percentage of pleural biopsy specimens. The degree of lymphocyte predominance in tuberculous pleurisy was lower than was previously thought. The lymphocyte percentage in pleural fluid was negatively associated with the probability of a positive effusion culture. With the implementation of a liquid culture method, the sensitivity of effusion culture was much higher than has been previously reported, and the combination of effusion and sputum cultures provided a good diagnostic yield.

    Tuberculous meningitis causes substantial mortality and morbidity in children and adults. More research is urgently needed to better understand the pathogenesis of disease and to improve its clinical management and outcome. A major stumbling block is the absence of standardised diagnostic criteria. The different case definitions used in various studies makes comparison of research findings difficult, prevents the best use of existing data, and limits the management of disease. To address this problem, a 3-day tuberculous meningitis workshop took place in Cape Town, South Africa, and was attended by 41 international participants experienced in the research or management of tuberculous meningitis. During the meeting, diagnostic criteria were assessed and discussed, after which a writing committee was appointed to finalise a consensus case definition for tuberculous meningitis for use in future clinical research. We present the consensus case definition together with the rationale behind the recommendations. This case definition is applicable irrespective of the patient's age, HIV infection status, or the resources available in the research setting. Consistent use of the proposed case definition will aid comparison of studies, improve scientific communication, and ultimately improve care. Copyright © 2010 Elsevier Ltd. All rights reserved.

  20. Tuberculous peritonitis in a German patient with primary biliary cirrhosis: a case report

    Full Text Available Abstract Background The number of cases of tuberculosis as a complication in people with immunodeficiency, people on immunosuppressive therapy and among the immigrant population is increasing in Germany. However, tuberculous peritonitis rarely occurs without these risks, particularly in Germans. The incidence of tuberculous peritonitis in Germany is very low; tuberculosis of the intestinal tract was found in approximately 0.8 % of tuberculosis cases in 2004. The diagnosis of tuberculous peritonitis is often delayed on account of non-specific clinical symptoms. The absence of specific biological markers, long incubation times for cultures and non-specific radiographic or ultrasonographic signs increase the morbidity associated with this treatable condition. Case presentation We report a case of tuberculous peritonitis in a 73-year-old female German patient. Her medical history revealed primary biliary cirrhosis (PBC since 1992. On admission, she complained of abdominal pain, vomiting, ascites and peripheral edema. The patient has been in a seriously reduced general condition and had fever up to 39.6°C. A few weeks earlier, the patient was in another hospital with the same complaint. Inflammatory parameters were elevated, but the procalcitonin level was normal. Blood culture was always negative, as was the tuberculin test. Ultrasonography of the abdomen showed massive ascites with multiple septa. The patient underwent a computed tomography (CT scan of the abdomen which showed a thickened intestinal wall in the sigmoid colon and a pronounced enhancement of the peritoneum. Computed tomography scans of the lung showed only slight bilateral pleural effusion. Because of the anaesthetic and bleeding risk due to thrombocytopenia, laparoscopy was not immediately undertaken. The culture from ascites was positive for M.tuberculosis after three weeks. Conclusion In primary biliary cirrhosis patients with non-specific clinical symptoms, such as vomiting

    Background The value of magnetic resonance imaging (MRI) signs in differentiating Ewing sarcoma from osteomyelitis has not be thoroughly investigated. Purpose To investigate the value of various MRI signs in differentiating Ewing sarcoma from osteomyelitis. Material and Methods Forty-one patients who underwent MRI because of a bone lesion of unknown nature with a differential diagnosis that included both Ewing sarcoma and osteomyelitis were included. Two observers assessed several MRI signs, including the transition zone of the bone lesion, the presence of a soft-tissue mass, intramedullary and extramedullary fat globules, and the penumbra sign. Results Diagnostic accuracies for discriminating Ewing sarcoma from osteomyelitis were 82.4% and 79.4% for the presence of a soft-tissue mass, and 64.7% and 58.8% for a sharp transition zone of the bone lesion, for readers 1 and 2 respectively. Inter-observer agreement with regard to the presence of a soft-tissue mass and the transition zone of the bone lesion were moderate (κ = 0.470) and fair (κ = 0.307), respectively. Areas under the receiver operating characteristic curve of the diameter of the soft-tissue mass (if present) were 0.829 and 0.833, for readers 1 and 2 respectively. Mean inter-observer difference in soft-tissue mass diameter measurement ± limits of agreement was 35.0 ± 75.0 mm. Diagnostic accuracies of all other MRI signs were all value in this setting.

    The modern concept of comprehensive medical rehabilitation of children with complications of osteomyelitis should include an interdisciplinary approach involving orthopedic and maxillofacial surgeons. Early diagnosis in children ensures the timely formation of individualized rehabilitation programs, designed to improve the anatomical and functional characteristics of the affected bones. Along with comprehensive orthopedic treatment, bone-reconstructive surgery of the facial bones of the skull should be focused on restoration of chewing function, external respiration, speech, and facial esthetics.

    Here we present the case of an 80-year-old man who developed a type II endoleak following endovascular abdominal aortic aneurysm repair. Initial attempts at treating the endoleak via a transarterial approach were unsuccessful; therefore the patient underwent percutaneous translumbar endoleak embolization. Approximately 1 month following the translumbar procedure, he developed back pain, with subsequent workup revealing osteomyelitis and discitis as a complication following repair via the translumbar approach.

    2013-06-01

    Full Text Available Variceal bleeding and hepatorenal syndrome (HRS are serious and life-threatening complications of advanced liver disease. Terlipressin is widely used to manage both acute variceal bleeding and HRS due to its potency and long duration of action. The most severe (though rare adverse event is ischemia. The present report describes the case of a patient with gangrene and osteomyelitis secondary to terlipressin therapy. A 71-year-old male with alcoholic liver cirrhosis (Child-Pugh B and chronic hepatitis C was admitted due to a drowsy mental status. The patient had several experiences of orthopedic surgery. His creatinine level had gradually elevated to 4.02 mg/dL, and his urine output decreased to 500 mL/24 hr. The patient was diagnosed as having grade III hepatic encephalopathy (HE and type II HRS. Terlipressin and albumin were administered intravenously to treat the HRS over 11 days. Although he recovered from the HE and HRS, the patient developed peripheral gangrene and osteomyelitis in both feet. His right toes were cured with the aid of rescue therapy, but his left three toes had to be amputated. Peripheral gangrene and osteomyelitis secondary to terlipressin therapy occur only rarely, and there is no specific rescue therapy for these conditions. Thus, attention should be paid to the possibility of ischemia of the skin and bone during or after terlipressin therapy.

    The aim of this study was to present a 15-year experience and provide a comprehensive analysis of a large cohort of patients with Pseudomonas aeruginosa osteomyelitis. We reviewed the medical records of patients admitted to a large French university hospital for P. aeruginosa osteomyelitis over a 15-year period. Patient outcome was assessed at follow-up after at least six months. Sixty-seven patients were included, comprising 57% with chronic osteomyelitis. Polymicrobial infection was predominant (63%), and an infected device was involved in 39% patients. The overall treatment success rate was 79.1%. All but one patient were treated with a combination of surgery and antibiotic therapy. The antibiotic treatment had a mean duration of 45 days (range, 21-90 days). Single-antibiotic therapy was preferred in nearly all cases. Treatment failure was reported for 14 (21%) patients and was due to the persistence of P. aeruginosa in four cases. No significant risk factor for treatment failure was identified, especially when treatment strategies were compared. We advocate optimal surgical debridement combined with initial parenteral antibiotics for a maximum of 15 days, followed by an oral fluoroquinolone. Total treatment duration should not exceed six weeks, and antibiotic treatment with two-drug combinations does not seem necessary. Copyright © 2017 The British Infection Association.

    Magnetic resonance imaging (MRI) has been recognized as the most accurate imaging modality for the detection of diabetic foot osteomyelitis. However, how accurately MRI displays the extent of diabetic foot osteomyelitis in the presence of ischemia is still unclear. We retrospectively compared the preoperative MRI findings with the results of histopathologic examinations of resected bones and studied the efficacy of MRI in the diagnosis of diabetic foot osteomyelitis of different etiologies. A total 104 bones from 18 foot ulcers in 16 diabetic patients (10 men and 6 women; age range 42 to 84 years) treated by surgical intervention from 2008 to 2012 was examined. In 8 neuropathic ulcers, 29 bones were accurately diagnosed in detail using MRI, even those with severe soft tissue infection. Of 75 bones in 10 ischemic ulcers, only 7 bones evaluated by MRI after revascularization were diagnosed accurately; the other 68 could not be diagnosed because of unclear or equivocal MRI findings. On histopathologic examination, all the bones were found to be infected through the bone cortex by the surrounding infected soft tissue, not directly by articulation. Overall, preoperative MRI is effective in the diagnosis of neuropathic ulcers, but less so of ischemic ones. Copyright © 2013 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.

  8. Actinomycotic Osteomyelitis of Maxilla Presenting as Oroantral Fistula: A Rare Case Report

    2015-01-01

    Full Text Available Actinomycosis is a chronic granulomatous infection caused by Actinomyces species which may involve only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is relatively rare when compared to mandible. These are normal commensals and become pathogens when they gain entry into tissue layers and bone where they establish and maintain an anaerobic environment with extensive sclerosis and fibrosis. This infection spreads contiguously, frequently ignoring tissue planes and surrounding tissues or organ. The portal of entry may be pulpal, periodontal infection, and so forth which may lead to involvement of adjacent structures as pharynx, larynx, tonsils, and paranasal sinuses and has the propensity to damage extensively. Diagnosis is often delayed and is usually based on histopathology as they are cultured in fewer cases. The chronic clinical course without regional lymphadenopathy may be essential in diagnosis. The management of actinomycotic osteomyelitis is surgical debridement of necrotic tissue combined with antibiotics for 3–6 months. The primary actinomycosis arising within the maxilla with contiguous involvement of paranasal sinus with formation of oroantral fistula is rare. Hence, we present a 50-year-old female patient with chronic sclerosing osteomyelitis of maxilla which presented as oroantral fistula with suppurative and sclerotic features.

  9. A New Type of Biphasic Calcium Phosphate Cement as a Gentamicin Carrier for Osteomyelitis

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Osteomyelitis therapy is a long-term and inconvenient procedure for a patient. Antibiotic-loaded bone cements are both a complementary and alternative treatment option to intravenous antibiotic therapy for the treatment of osteomyelitis. In the current study, the biphasic calcium phosphate cement (CPC, called α-TCP/HAP (α-tricalcium phosphate/hydroxyapatite biphasic cement, was prepared as an antibiotics carrier for osteomyelitis. The developed biphasic cement with a microstructure of α-TCP surrounding the HAP has a fast setting time which will fulfill the clinical demand. The X-ray diffraction and Fourier transform infrared spectrometry analyses showed the final phase to be HAP, the basic bone mineral, after setting for a period of time. Scanning electron microscopy revealed a porous structure with particle sizes of a few micrometers. The addition of gentamicin in α-TCP/HAP would delay the transition of α-TCP but would not change the final-phase HAP. The gentamicin-loaded α-TCP/HAP supplies high doses of the antibiotic during the initial 24 hours when they are soaked in phosphate buffer solution (PBS. Thereafter, a slower drug release is produced, supplying minimum inhibitory concentration until the end of the experiment (30 days. Studies of growth inhibition of Staphylococcus aureus and Pseudomonas aeruginosa in culture indicated that gentamicin released after 30 days from α-TCP/HAP biphasic cement retained antibacterial activity.

    The objective of the present study was to develop a scientifically sound rationale for the application of infrared laser radiation (IRLR) either separately or in the combination with fluctuation magnetic therapy in the medical rehabilitation of the children presenting with chronic hematogenous osteomyelitis. Another objective was to evaluate the clinical effectiveness of this therapeutic modality. Two achieve these goals, the clinical observations and special research studies were conducted in two directions with the participation of 95 patients at the age varying from 1 to 15 years. The study has demonstrated the effectiveness of the inclusion of IRLR in the medical rehabilitation program for the children with chronic hematogenous osteomyelitis in different periods of the disease. It was shown that the transcutaneous infrared irradiation of the affected area during the exacerbation of chronic osteomyelitis had a well apparent immunostimulatory effect and reduced the activity of the inflammatory process. The application of IRLR in combination with fluctuation magnetic therapy during the period of partial remission, had a more pronounced influence on the microcirculation and stimulated the regenerative and trophic processes.

  11. Rare Case of Aspergillus ochraceus Osteomyelitis of Calcaneus Bone in a Patient with Diabetic Foot Ulcers

    2015-01-01

    Full Text Available Diabetes is the most common metabolic disease in humans. One of the major complications of the disease is foot ulcer that is prone to infection. The most common causes of infection which have been reported in these patients are bacteria and fungi such as Candida, Aspergillus, and Rhizopus species. We report one such rare case with calcaneal osteomyelitis caused by Aspergillus ochraceus in a patient with diabetic foot osteomyelitis. The case was a 68-year-old male with a history of type II diabetes for 2 years. The patient had two ulcers on the right heel bones for the past 6 months with no significant improvement. One of the most important predisposing factors to infectious diseases, especially opportunistic fungal infection, is diabetes mellitus. Aspergillus species can involve bony tissue through vascular system, direct infection, and trauma. Proper and early diagnosis and treatment of diabetic foot infection can reduce or prevent complications, such as osteomyelitis and amputation. The annual examination of feet for skin and nail lesion, sensation, anatomical changes, and vascular circulation can be useful for prevention and control of infection.

    2013-03-01

    Osteomyelitis frequently complicates infections in the feet of patients with diabetes. Gram-positive cocci, especially Staphylococcus aureus, are the most commonly isolated pathogens, but gram-negative bacteria also cause some cases of diabetic foot osteomyelitis (DFO). These gram-negatives require different antibiotic regimens than those commonly directed at gram-positives. There are, however, few data on factors related to their presence and how they influence the clinical picture. We conducted a retrospective study to determine the variables associated with the isolation of gram-negative bacteria from bone samples in cases of DFO and the clinical presentation of these infections. Among 341 cases of DFO, 150 had a gram-negative isolate (alone or combined with a gram-positive isolate) comprising 44.0% of all patients and 50.8% of those with a positive bone culture. Compared with gram-positive infections, wounds with gram-negative organisms more often had a fetid odor, necrotic tissue, signs of soft tissue infection accompanying osteomyelitis, and clinically severe infection. By multivariate analysis, the predictive variables related to an increased likelihood of isolating gram-negatives from bone samples were glycated hemoglobin gram-negatives had a statistically significantly higher prevalence of leukocytosis and higher white blood cell counts than those without gram-negatives. In conclusion, gram-negative organisms were isolated in nearly half of our cases of DFO and were associated with more severe infections, higher white blood cell counts, lower glycated hemoglobin levels, and wounds of traumatic etiology.

    2017-12-01

    Full Text Available Osteomyelitis is an infection of bone which may be caused by infection carried to the bone via the bloodstream or from surrounding tissue. Treatment of osteomyelitis of the mandible is extremely difficult because of oral environment and teeth presence. Management often involves both debridement and antibiotic selection. Despite this, aggressive surgical interventions and conservative therapy are most important aspects of treatment. Medication-related osteonecrosis of the jaw (MRONJ is an avascular necrosis related to osteomyelitis and characterized by necrotic bone in the maxillofacial region. The prevalence of this is associated with treatment with high-potency bisphosphonates or denosumab and it seems to be getting increasingly frequent. Due to lack of prospective studies with long-term follow-up there are no recommendation for treatment of MRNOJ. The main aim of treatment of patients with MRNOJ is to continue and to support oncological treatment as well as to provide patient education, comfort to life, control of pain and to prevent from secondary infection and development of new areas of necrosis.

    The current study was designed to explore the epidemiology of extremities chronic osteomyelitis, its prognosis and the complications of the treatment methods being used in southwest China. The data from osteomyelitis patients treated at the Department of Orthopaedics, Southwest Hospital, China between May 2011 and September 2016 were collected and analysed. The study comprised 503 admitted patients, of which 416 males and 87 were females, with an average age of 40.15 ± 5.64 years. Approximately 356 cases were followed for more than 18 months; the average bone union time was 6.24 ± 0.76 months in 94.1% (335) patients, and infections were almost controlled in 93.8% patients. The rate of infection control with the induced membrane technique was higher than with the I-stage free bone graft. Iliac infection was the main complication of the induced membrane technique, and impaired joint activity was the main complication of I-stage free bone grafts. In southwest China, the incidence of haematogenous osteomyelitis, caused mainly by Staphylococcus aureus, remains very high. The speed of bone defect repair and the rate of infection control with the induced membrane technique were superior to those of I-stage free bone grafts. Internal fixation should be given priority because it offers reduced complications with no increase in the recurrence of infection.

    2016-11-01

    Full Text Available Recently, the number of cases of animal bite wounds has increased significantly in concordance with an increase in the pet population around the world. The authors report two rare cases of osteomyelitis of the phalanx following cat and dog bites. On initial physical examination, signs of a severe infection were observed. Radiographs of both patients showed the presence of osteomyelitis, and in one of the patients, the diagnosis was confirmed with a bone biopsy. After use of empirical antibiotics, intravenous antibiotic therapy that matched the identified bacterium's sensitivity was initiated, and at the same time, secure dressing including debridement was performed to induce secondary healing. In addition, the patients were closely monitored with serial X-rays, and culture and blood test follow-up. One patient fully recovered without sequelae, but the other patient suffered a loss of distal interphalangeal joint motion. When dealing with bite wounds located on the hand, it is important to visit the hospital as soon as possible and receive the appropriate treatment early. Moreover, to prevent severe complications such as osteomyelitis, it is important to administer antibiotic therapy to which the cultured bacteria are sensitive, along with proper wound management and prophylactic antibiotic treatment.

    2017-09-01

    Streptococcus milleri (Streptococcus anginosus, intermedius and constellatus) are commensal organisms, which can become pathogenic and cause infection with frequent abscess formation, local or metastatic extension. Osteomyelitis of the skull has been rarely reported in this type of infection. Skull osteomyelitis due to Streptococcus milleri is reported in a 61-year-old immunocompetent man without any medical history, occurring 10 months after a head injury without any wound or complication at initial presentation. A progressive right parieto-occipital headache with worsening and increased acute phase reactants evoked a giant cell arteritis. After few days of corticosteroid therapy (0.5 mg/kg/day), diagnosis of subcutaneous abscess associated to an extensive osteomyelitis of the skull due to Streptococcus milleri was diagnosed. The outcome was favorable after drainage of one liter of pus, irrigation, debridement and antibiotherapy by amoxicillin for 8 weeks. It is necessary to discuss the differential diagnosis of giant cell arteritis particularly when symptoms are unusual. Even a short-term corticosteroid therapy may dramatically exacerbate an undetected infection. Copyright © 2017. Published by Elsevier SAS.

  17. Is there a simple, definitive, and cost-effective way to diagnose osteomyelitis in the pressure ulcer patient?

    Larson, David L; Gilstrap, Jarom; Simonelic, Kevin; Carrera, Guillermo F

    2011-02-01

    Despite advances in managing pressure ulcers, there is still no definitive way to diagnose bone infection (osteomyelitis) short of open biopsy. An effective, less invasive diagnostic method might result in cost savings and improved care; however, needle aspiration, computed tomography scan, magnetic resonance imaging, ultrasound, and bone scans have proven unsatisfactory in predicting osteomyelitis. The authors reviewed preoperative radiologic studies of stage IV pressure ulcer patients and their bone biopsy results to determine which radiologic studies are most diagnostic for osteomyelitis. Patients (n = 44) having surgical débridement of stage IV ulcers with open bone biopsy after prior radiographic imaging (plain films, ultrasound, computed tomography, magnetic resonance imaging, and/or nuclear bone scans) were included. Studies were interpreted by a single musculoskeletal radiologist blinded to information from the medical record and following standard radiologic criteria for the diagnosis of osteomyelitis. The percentage of patients with biopsy-proven osteomyelitis identified with imaging was 50 percent using a computed tomography scan and 88 percent using a plain film of the bony area of involvement. The overall sensitivity of either radiologic study was 61 percent. The percentage of patients without osteomyelitis identified as not having the condition by imaging was 85 percent for the computed tomography scan and 32 percent for the plain film. Overall specificity of both studies was 69 percent. Preoperative radiologic studies for osteomyelitis in a pressure ulcer are far from definitive; however, if a radiologic study is used to make that diagnosis in a stage IV pressure ulcer, it would appear that a plain film would suffice.

    Although CT scanning is used widely for making the diagnosis and detecting the complications of tuberculous meningitis (TBM) in children, the radiological features are considered non-specific. CT is particularly suggestive of the diagnosis when there is a combination of basal enhancement, hydrocephalus and infarction, and even then the diagnosis may be in doubt. In this paper we introduce a new CT feature for making the diagnosis of TBM, namely, hyperdensity in the basal cisterns on non-contrast scans, and we assess which of the recognized CT features is most sensitive and specific. To determine the sensitivity and specificity of the presence of high-density exudates in the basal cisterns (on non-contrast CT) and basal enhancement (on contrast-enhanced CT) for the diagnosis of TBM in children, and to correlate these with the complications of infarction and hydrocephalus. Retrospective review of CT scans with readers blinded to the diagnosis, which was based on a definitive culture of cerebrospinal fluid (CSF) for TBM or other bacteria. Computer-aided conversion of hard-copy film density to Hounsfield units was employed as well as a density threshold technique for determining abnormally high densities. The most specific feature for TBM is hyperdensity in the basal cisterns prior to IV contrast medium administration (100%). The most sensitive feature of TBM is basal enhancement (89%). A combination of features (hydrocephalus, infarction and basal enhancement) is as specific as pre-contrast hyperdensity, but has a lower sensitivity (41%). There were statistically significant differences in the presence of hydrocephalus (p=0.0016), infarcts (P=0.0014), basal enhancement (P<0.0001) and pre-contrast density (P<0.0001) between the negative and positive TBM patient groups. The presence of granulomas was not statistically significant between the two groups (P=0.44).

    To evaluate the response of mandibular osteomyelitis treated by surgical decortication with disruption of the affected adjacent periosteum in concert with long-term targeted antibiotic therapy. The hypothesis is that, by removing the buccal cortical plate and disrupting the hypertrophically inflamed adjacent periosteum, the medullary bone will be brought in contact with bleeding tissue and circulating immunologic factors and antibiotics, which will promote definitive resolution. A retrospective review was conducted of 7 patient charts with associated radiographs from November 2010 to August 2016 treated by the first author at the University of Tennessee Medical Center (Knoxville, TN). Patients with chronic suppurative or nonsuppurative osteomyelitis of the mandible without condylar involvement or pathologic fracture were selected and treated with decortication with periosteal disruption in combination with long-term targeted antibiotic therapy. Seven patients (3 women and 4 men; mean age, 60 yr) underwent decortication with periosteal disruption of the affected area and received at least 6 weeks of targeted intravenous antibiotics. Computed tomography was performed preoperatively and a repeat study was performed after completion of antibiotics. In each case, post-treatment imaging showed definitive resolution after treatment with decortication in concert with disruption of the inflamed hypertrophic periosteum and intravenous antibiotics. Debridement of the infected cortical bone with restoration of the blood supply through disruption of the adjacent periosteum provided definitive resolution of mandibular osteomyelitis in the 7 patients treated. The hypothesis is that disruption of the affected adjacent periosteum reintroduces an immune-mediated response in concert with improved antibiotic delivery to and penetrance of the diseased mandible, aiding in definitive resolution. Decortication with periosteal disruption allows for preservation of the inferior alveolar

    Full Text Available We report a case of paradoxical deterioration. A male patient diagnosed with pleural tuberculosis, but who was not infected with human immunodeficiency virus (HIV, experienced clinical deterioration 3 weeks after the initiation of anti-tuberculous treatment. After other diagnoses were ruled out, a paradoxical response to treatment was established and the patient was started on systemic corticosteroids. Paradoxical response to treatment should be considered in patients with clinical deterioration after they start on anti-tuberculous treatment.

    Vertebral compression fracture (VCF) is an important cause of severe debilitating back pain, adversely affecting quality of life, physical function, psychosocial performance, mental health and survival. Different vertebral augmentation procedures (VAPs) are used in order to consolidate the VCFs, relief pain,and whenever posible achieve vertebral body height restoration. In the present review we give the indications, contraindications, safety profile and outcomes of the existing percutaneous VAPs.

    2017-01-01

    To evaluate the variability of clinical treatment and outcomes based on reporting of diabetic foot ulcer MRI findings of adjacent marrow T2 hyperintensity with normal T1 signal. A retrospective review was conducted of 46 MRI examinations evaluating diabetic foot ulcers that demonstrated normal T1 marrow signal, but T2 marrow hyperintensity deep to the ulcer. The cohort was divided based on MRI report impressions into three groups; ''osteitis without osteomyelitis'' (OW), ''osteitis but cannot exclude early osteomyelitis'' (OCEO) and ''early osteomyelitis'' (EO). Patient demographics (age, gender) and accessory MRI findings of ulcer and sinus tract depth were recorded. Initial clinical assessment and medical treatment (route and duration of antibiotics), healing versus disease progression and histology or microbiology results were recorded. The isolated marrow T2 signal hyperintensity was reported as OW in 12 patients, OCEO in 18, and EO in 16. No statistical difference in clinical assessment was demonstrated between the OW, OCEO, and EO groups. Pathological condition was available in 15 patients within 0-7 days (mean 2.4 days) of the MRI examination, with 14 (93%) of these positive for osteomyelitis by histopathology or positive cultures. Initial diagnosis of or progression to osteomyelitis was shown in 28 patients (61%). Treatment of suspected osteomyelitis is heavily determined by clinical factors. Patients who initially demonstrate only T2 marrow signal abnormality under a diabetic ulcer are eventually diagnosed as osteomyelitis in 61% of cases and deserve aggressive treatment as early osteomyelitis when meeting clinical parameters.

    In order to evaluate the value of vertebral angiography in assesment of hemifacial spasm, We reviewed retrospectively the vertebral angiography of 28 patients (30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery , posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa

    Osteopetrosis is a rare genetic bone disorder arising due to a defect in the differentiation or function of osteoclast which results in a generalized increase in bone mass. Osteomyelitis is one of the most common complications because of decreased bone marrow function and compromised blood supply. Radiologist plays a vital role in diagnosing osteopetrosis. Here, we present two cases of autosomal dominant osteopetrosis Type II (ADO II) with secondary osteomyelitis changes which were reported to our department. One of these two cases presented with secondary osteomyelitis in both maxilla and mandible and features of rickets, which is very rarely seen in ADO II. To the best of our knowledge, the presentation of rickets with ADO is the first of its kind to be reported. In this paper, we describe the clinical and radiological features leading to the diagnosis of ADO in these two patients. Further, a review of the literature regarding ADO is discussed.

    Full Text Available Background: The literature on paediatric osteomyelitis in the developing world is scarce, and there have been calls for further characterisation of its epidemiology and the identification of factors that limit effective management in order to guide local service delivery. Our centre is a hospital serving a population of 11 million people in Tanzania. Materials and Methods: We identified patients 3 months. Twelve out of 13 with a time from symptom onset to presentation of <2 months did not develop recurrence. Conclusions: This is, to the best of our knowledge, the second largest study of paediatric osteomyelitis in the developing world. Major challenges facing this centre include a lack of availability of bacterial cultures and failure to attend follow-up. Delayed presentation of osteomyelitis to our centre is associated with recurrence of infection.

    The clinical records and scintigrams of patients with sickle cell hemoglobinopathies in whom acute symptoms developed suggestive of possible osteomyelitis and who had undergone sequential Tc-99m bone marrow scans and gallium scintigraphy of the affected sites were reviewed. Osteomyelitis was correctly diagnosed in six of 18 cases when gallium was focally increased relative to a site of decreased or absent bone marrow activity. Of 12 episodes of infarction, both studies showed focally decreased activity in a concordant manner in 11. The remaining, false-positive study indicated slightly increased gallium in 11. The remaining, false-positive indicated slightly increased gallium concentration at a site of decreased bone marrow activity. Overall, a protocol of sequential Tc-99m bone marrow scans and gallium scintigraphy is an effective means of distinguishing osteomyelitis from infarction in patients with sickle cell hemoglobinopathies

    Children with sickle cell disease (SCD) are at risk of bone infarcts and acute osteomyelitis. The clinical differentiation between a bone infarct and acute osteomyelitis is a diagnostic challenge. Unenhanced T1-W fat-saturated MR images have been proposed as a potential tool to differentiate bone infarcts from osteomyelitis. To evaluate the reliability of unenhanced T1-W fat-saturated MRI for differentiation between bone infarcts and acute osteomyelitis in children with SCD. We retrospectively reviewed the records of 31 children (20 boys, 11 girls; mean age 10.6 years, range 1.1-17.9 years) with SCD and acute bone pain who underwent MR imaging including unenhanced T1-W fat-saturated images from 2005 to 2010. Complete clinical charts were reviewed by a pediatric hematologist with training in infectious diseases to determine a clinical standard to define the presence or absence of osteomyelitis. A pediatric radiologist reviewed all MR imaging and was blinded to clinical information. Based on the signal intensity in T1-W fat-saturated images, the children were further classified as positive for osteomyelitis (low bone marrow signal intensity) or positive for bone infarct (high bone marrow signal intensity). Based on the clinical standard, 5 children were classified as positive for osteomyelitis and 26 children as positive for bone infarct (negative for osteomyelitis). The bone marrow signal intensity on T1-W fat-saturated imaging was not significant for the differentiation between bone infarct and osteomyelitis (P = 0.56). None of the additional evaluated imaging parameters on unenhanced MRI proved reliable in differentiating these diagnoses. The bone marrow signal intensity on unenhanced T1-W fat-saturated MR images is not a reliable criterion to differentiate bone infarcts from osteomyelitis in children.

    We report a prevalent finding in tuberculous lymphadenitis (TL): Starry sky sign, hyperechoic foci without acoustic shadows over a hypoechoic background. We retrospectively searched the database for a possible relationship of starry sky sign with a specific diagnosis and also the prevalence and accuracy of the finding. Starry sky sign was found in 16 of 31 tuberculous lymph nodes, while none of other lymph nodes (1,015 lymph nodes) exhibited this finding; giving a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 51.6%, 100%, 100%, 98.5%, and 98.5%, respectively. Bacteriologic and histologic findings are gold standard in the diagnosis of tuberculosis, but this finding may guide the bronchoscopist in choosing the more pathologic node within a station and increase the diagnostic yield as it may relate to actively dividing mycobacteria.

    A 32 years old male patient is described with infection by the human immunodeficiency virus (HIV) on stage IV C1 and with positive Ag p24 who developed tuberculous meningitis of atypical presentation. A persistent liquoral neutrophilia and low adenosindeaminase values were observed in cerebrospinal fluid of purulent appearance. The patient responded badly to tuberculostatic treatment and died. In the antibiogram carried out resistance to Mycobacterium tuberculosis was observed to rifampicine and isoniazide, two of the five drugs the patient had received. The peculiarities of the clinical form of presentation similar to purulent bacterian meningitis are discussed, and the possible influence of HIV infection and the antibiotic multiresistance observed in the bad evolution of the tuberculous meningitis which the patient developed.

We retrospectively compared the culture yield, time to positivity, and contamination rate of pleural effusion samples in the BACTEC Mycobacteria Growth Indicator Tube 960 (MGIT) and Ogawa media among patients with tuberculous pleurisy. Out of 104 effusion samples, 43 (41.3%) were culture positive on either the MGIT or the Ogawa media. The culture yield of MGIT was higher (40.4%, 42/104) than that of Ogawa media (18.3%, 19/104) (Pliquid culture system could provide approximately twice as high yields and fast results in effusion culture, compared to solid media. Supplemental solid media may have a limited impact on maximizing sensitivity in effusion culture; however, further studies are required.

    Tuberculous involvement of the spinal subdural and intramedullary compartments is extremely uncommon. Simultaneous involvement of both compartments has never been reported, to our knowledge. We present an HIV-positive patient with such kind of combined involvement. Diagnosis was made on the basis of a prior history of pulmonary tuberculous infection and a positive therapeutic response to antituberculous chemotherapy. Magnetic resonance imaging is the diagnostic procedure of choice in order to determine the exact level, site, and size of the disease. Tuberculosis of the spine should always be considered in the differential diagnosis of spinal cord compression if the patient lives in or comes from a region where tuberculosis is endemic or if the patient is immunocompromised.

    In this work, we define the requirements for a human-based osteomyelitis model which overcomes the limitations of state of the art animal models. Osteomyelitis is a severe and difficult to treat infection of the bone that develops rapidly, making it difficult to study in humans. We have developed a 3D in vitro model of the bone marrow, comprising a macroporous material, human hematopoietic stem and progenitor cells (HSPCs) and mesenchymal stromal cells (MSCs). Inclusion of biofilms grown on an implant into the model system allowed us to study the effects of postoperative osteomyelitis-inducing bacteria on the bone marrow. The bacteria influenced the myeloid differentiation of HSPCs as well as MSC cytokine expression and the MSC ability to support HSPC maintenance. In conclusion, we provide a new 3D in vitro model which meets all the requirements for investigating the impact of osteomyelitis. Implant associated-osteomyelitis is a persistent bacterial infection of the bone which occurs in many implant patients and can result in functional impairments or even entire loss of the extremity. Nevertheless, surprisingly little is known on the triangle interaction between implant material, bacterial biofilm and affected bone tissue. Closing this gap of knowledge would be crucial for the fundamental understanding of the disease and the development of novel treatment strategies. For this purpose, we developed the first biomaterial-based system that is able to mimic implant-associated osteomyelitis outside of the body, thus, opening the avenue to study this fatal disease in the laboratory.

    The construction of the vertebral column has been used as a key anatomical character in defining and diagnosing early tetrapod groups. Rhachitomous vertebrae--in which there is a dorsally placed neural arch and spine, an anteroventrally placed intercentrum and paired, posterodorsally placed pleurocentra--have long been considered the ancestral morphology for tetrapods. Nonetheless, very little is known about vertebral anatomy in the earliest stem tetrapods, because most specimens remain trapped in surrounding matrix, obscuring important anatomical features. Here we describe the three-dimensional vertebral architecture of the Late Devonian stem tetrapod Ichthyostega using propagation phase-contrast X-ray synchrotron microtomography. Our scans reveal a diverse array of new morphological, and associated developmental and functional, characteristics, including a possible posterior-to-anterior vertebral ossification sequence and the first evolutionary appearance of ossified sternal elements. One of the most intriguing features relates to the positional relationships between the vertebral elements, with the pleurocentra being unexpectedly sutured or fused to the intercentra that directly succeed them, indicating a 'reverse' rhachitomous design. Comparison of Ichthyostega with two other stem tetrapods, Acanthostega and Pederpes, shows that reverse rhachitomous vertebrae may be the ancestral condition for limbed vertebrates. This study fundamentally revises our current understanding of vertebral column evolution in the earliest tetrapods and raises questions about the presumed vertebral architecture of tetrapodomorph fish and later, more crownward, tetrapods.

    Full Text Available Tuberculous mastititis is a rare clinical entity and usually affects women from the Indian subcontinent. It often mimics breast carcinoma and pyogenic breast abscess. Fine needle aspiration cytology (FNAC is a very essential diagnostic tool when other routine laboratory investigations are not helpful in reaching to the conclusion. Tuberculosis (TB of the breast is an uncommon presentation of TB even in countries where the incidence of pulmonary and extrapulmonary TB is high. Radiological imaging is not diagnostic.

  6. The use of technetium-99m-DTPA in the diagnosis of tuberculous meningitis

    1988-03-01

    As 82 Br is not available locally in South West Africa on a daily basis a technetium preparation, 99m Tc-DTPA, was used in the diagnosis of patients with tuberculous meningitis. The 99m Tc-DTPA partition test was compared with the 82 Br partition test on 22 trial subjects. The trial subjects varied in age (0,8-57 years), sex and race. There were 7 patients diagnosed by the clinicians as having tuberculous meningitis. All patients were placed on anti-tuberculous meningitis treatment and all, except 2, one of whom regressed and 1 who died 7 days later, improved slowly. The 9 patients with viral meningitis received no antibiotics and recovered rapidly on symptomatic treatment only. With all 5 the septic meningitis cases, the organism was identified and there was thus no diagnostic uncertainty. One normal control subject was also examined. It would appear from the results that both 82 Br, as well as 99m Tc-DTPA, cross the blood-brain barrier to a greater extent in the case of tuberculous meningitis, compared to viral meningitis. Although the accuracy of the 82 Br test, if a critical ratio value of 1,3 was chosen, is 90,6% compared to 86,9% of the 99m Tc-DTPA partition test if a critical ratio value of 3 was chosen, there are still advantages to the use of the technetium preparation. These include the availability, cost and lower radiation dose per MBq as well as the possibility of brain imaging. 10 figs., 58 refs., 9 tabs

    Background The optimal time to initiate antiretroviral therapy (ART) in human immunodeficiency virus (HIV)–associated tuberculous meningitis is unknown. Methods We conducted a randomized, double-blind, placebo-controlled trial of immediate versus deferred ART in patients with HIV-associated tuberculous meningitis to determine whether immediate ART reduced the risk of death. Antiretroviral drugs (zidovudine, lamivudine, and efavirenz) were started either at study entry or 2 months after randomization. All patients were treated with standard antituberculosis treatment, adjunctive dexamethasone, and prophylactic co-trimoxazole and were followed up for 12 months. We conducted intention-to-treat, per-protocol, and prespecified subgroup analyses. Results A total of 253 patients were randomized, 127 in the immediate ART group and 126 in the deferred ART group; 76 and 70 patients died within 9 months in the immediate and deferred ART groups, respectively. Immediate ART was not significantly associated with 9-month mortality (hazard ratio [HR], 1.12; 95% confidence interval [CI], .81–1.55; P = .50) or the time to new AIDS events or death (HR, 1.16; 95% CI, .87–1.55; P = .31). The percentage of patients with severe (grade 3 or 4) adverse events was high in both arms (90% in the immediate ART group and 89% in the deferred ART group; P = .84), but there were significantly more grade 4 adverse events in the immediate ART arm (102 in the immediate ART group vs 87 in the deferred ART group; P = .04). Conclusions Immediate ART initiation does not improve outcome in patients presenting with HIV-associated tuberculous meningitis. There were significantly more grade 4 adverse events in the immediate ART arm, supporting delayed initiation of ART in HIV-associated tuberculous meningitis.

    Full Text Available Introduction The aim of this study was to estimate the incidence of tuberculous meningitis in the State of Santa Catarina (SC, Brazil, during the period from 2001 to 2010. Methods Ecological, temporal, and descriptive methods were employed using data obtained from the Information System on Disease Notification (Sistema de Informação de Agravos de Notificação. Results One hundred sixteen reported cases of tuberculous meningitis occurred from 2001 to 2010, corresponding to 1.2% (0.2 cases/100,000 inhabitants of all meningitis cases reported in SC. There was a predominance of new cases in males, corresponding to 56.9% of new cases (0.2 cases/100,000 inhabitants; males vs. females; p=0.374, in patients aged 20-39 years, corresponding to 52.6% of new cases (0.5 cases/100,000 inhabitants; 20-39 years versus others; p<0.001, and in urban areas, corresponding to 91.4% of new cases (0.2 cases/100,000 inhabitants; urban vs. rural; p=0.003. In 48.3% of cases, the outcome was death. Conclusions The incidence rate of tuberculous meningitis in SC has increased within the last decade, with the most affected population comprising young adult white males with an average education. Thus, tuberculous meningitis remains a serious disease, emphasizing the need for disease prevention with vaccination campaigns against tuberculosis, the development of faster and more accurate diagnostic methods, and the use of current epidemiological knowledge regarding the disease to facilitate the establishment of early treatment.

    Medical records of 28 horses with osteomyelitis of the calcaneus were reviewed to evaluate signalment, history, diagnostic and treatment methods, outcome, and long-term follow-up information. Trauma was the most commonly reported cause (24). Physical examination revealed lameness in 27 horses, and 22 (79%) had a wound or draining tract over the plantar aspect of the calcaneus. Radiography of all horses was done prior to the initiation of treatment, and follow-up radiography was done on 20 horses. The most common radiographic findings were soft tissue swelling (25), bony lysis of the calcaneus (17), bone fragments or sequestra from the tuber calcis (13), and periosteal new bone production or bony lysis of the sustentaculum tali (5). Association could not be found between initial radiographic findings and eventual outcome of the case. Positive bacterial cultures were obtained from 13 horses. A wide variety of gram-positive, gram-negative, and anaerobic organisms were isolated. Fourteen of the 15 isolates, for which susceptibilities were reported, were susceptible to penicillin, gentamicin, or trimethoprim sulfamethoxazole. Twenty-six of the 28 horses diagnosed as having osteomyelitis of the calcaneus were treated; 16 horses were treated with surgical debridement in addition to antimicrobial treatment, and 10 horses were treated with antimicrobial agents, anti-inflammatory drugs, or supportive wound care. There was no significant difference in survival rate of horses treated surgically and those treated conservatively. Six horses that were treated were later euthanatized for problems associated with chronic osteomyelitis, and 2 horses died or were euthanatized for unrelated problems. Eighteen horses (64%) were alive at last follow-up

    Full text: We present an unusual case of multifocal osteomyelitis with minimal bone scan abnormalities and markedly discordant findings on Magnetic Resonance Imaging(MRI) and gallium scans. A seven-year-old female presented with left leg, right elbow pain and fever. A bone scan was performed. Mild increased vascularity was demonstrated on the dynamic and blood pool phases of the study in the area of the right elbow. In the delayed images there was a photopenic lesion in the left distal femoral metadiaphysis and also irregular uptake in the metaphyseal regions of the long bones. Low grade soft tissue tracer uptake was seen in the left thigh and right forearm. The patient deteriorated clinically and underwent further investigations with MRI and gallium scans. The MRI showed extensive abnormalities with mulitlocular fluid collection seen throughout most of the muscle groups of both thighs suggesting myositis with an associated cellulitis and osteomyelitis of the left femur. The gallium study was markedly abnormal with increased uptake in the distal 2/3rds of the left femur, proximal 1/2 of the right femur, right proximal forearm (mid forearm extending to mid upper arm), left proximal humerus and right hemithorax especially the lower zones. Staphylococcal aureus was cultured. The patient required intensive care management and slowly responded to antibiotic therapy and surgery to drain abscesses in the thighs. A bone marrow biopsy was normal and immunological tests were performed but a result has yet to be determined. The lack of increased bone uptake in the demonstrated areas of osteomyelitis maybe explained on the basis of an overwhelming infective process inhibiting the patient's healing response.

    Osteomyelitis is a major complication in patients with diabetic foot ulceration. Accurate pathogenic identification of organisms can aid the clinician to a specific antibiotic therapy thereby preventing the need for amputation. All diabetic patients with bone biopsy-confirmed osteomyelitis were included into the study: biopsies were performed either during surgical removal of infected bone or percutaneously under guided fluoroscopy through non-infected tissue. The depth and extent of the ulcer was assessed using a sterile blunt metal probe. Deep wound cultures were taken from the wound base after sharp debridement. Of 66 cases of suspected osteomyelitis in 102 joints, 34 patients had both bone biopsies and deep wound cultures over the study period. Thirty two of 34 (94%), had a history of preceding foot ulceration, and in 25 of the cases a positive probe to bone test was recorded. In a high proportion of patients, at least one similar organism was isolated from both the deep wound culture and bone biopsy procedures (25 of 34 cases, 73.5%, p<0.001). When organisms were isolated from both wound cultures and bone biopsies, the identical strain was identified in both procedures in a significant proportion of cases (16 of 25 cases, 64%, p<0.001, total sample analysis in 16 of 34 cases, 47%). Deep wound cultures correlate well with osseous cultures and provide a sensitive method in assessing and targeting likely pathogens that cause osseous infections. This will help aid the clinician in guiding antibiotic therapy in centers where bone biopsies may not be readily available. Copyright © 2013 John Wiley & Sons, Ltd.

    The results of treatment are analyzed in 51 patients (35 with exacerbation of chronic traumatic mandibular osteomyelitis and 16 with chronic traumatic mandibular osteomyelitis). Low-intensity pulsed magnetic therapy of the focus in combination with electric stimulation of segmentary bioactive points, synchronized by the patient's pulse, are proposed to be added to the therapeutic complex. Such a modality improved the regional hemodynamics, promoted liquidation of the postoperative edema on days 1-2 after intervention, and sooner than after traditional therapy repaired the energy of the patient's organism.

    Vertebral collapses are the most frequent fractures in osteoporosis. They are often overlooked, although their presence is a strong risk factor for development of new fractures. Lateral radiographs of the spine are the accepted standard for assessment of fractures. Qualitative (visual), semiquantitative and quantitative (morphometric) techniques are useful in determining the compressive deformities of vertebral bodies. In the present paper, the advantages and the disadvantages of these methods are discussed. The improvement of scan quality allows to use DXA technique to diagnose the fractures, in both - the visual and the morphometric way. The vertebral morphologic assessment also seems to be an important diagnostic tool in pediatric osteoporosis. Application of multidetector CT and especially MR in vertebral imaging of osteoporosis, improves the sensitivity of fracture detection and enables the differentiation of benign from malignant vertebral body collapses.

    Full Text Available Tuberculous meningitis (TBM is the most severe form of tuberculosis and is commoner in those with immunsuppression. Diagnosis continues to be difficult particularly in resource limited settings, and this may be truer in the setting of pregnancy. We report the case of a pregnant Nigerian who was diagnosed late with atypical features of TBM complicated by cerebral infarction. High index of suspicion and early administration of anti-tuberculous medications as daily therapy according to the national treatment guidelines: 600 mg Rifampicin, 300 mg Isoniazid, 1.2g Pyrazinamide and 800 mg Ethambutol plus 50 mg pyridoxine and 0.4 mg/kg body weight/day dexamethasone which was tapered weekly led to a slow but sustained clinical improvement. The relationship between pregnancy, susceptibility to TBM and presenting features of TBM requires further exploration. Clinicians should also be aware of atypical presentation of TBM in pregnancy, and the suspicion of TBM may be sufficient grounds to initiate empirical anti-tuberculous therapy.

    East Nusa Tenggara (NTT) and Central Java Provinces, Indonesia. To estimate the average annual risk of tuberculous infection (ARTI) among school children aged 6-9 years in each province. Children attending Classes 1-4 in 65 schools in NTT and 79 in Central Java, selected by two-stage sampling, were intradermally administered 2 tuberculin units of purified protein derivative RT23 with Tween 80 on the mid-volar aspect of the left forearm. The maximum transverse diameter of induration was measured 72 h later. The analysis was carried out among 5479 satisfactorily test-read children in NTT and 6943 in Central Java. One hundred and fifty-five new sputum smear-positive pulmonary tuberculosis (PTB) cases (78 in NTT and 77 in Central Java) were also tuberculin tested. Based on the frequency distribution of reaction sizes among the children and PTB cases, the prevalence of infection was estimated by the mirror-image method using the modes of tuberculous reactions at 15 and 17 mm. Using the 15 mm mode, ARTI was estimated at 1% in NTT and 0.9% in Central Java. Using the 17 mm mode, ARTI was estimated at 0.5% in NTT and 0.4% in Central Java. Transmission of tuberculous infection may be further reduced by intensification of tuberculosis control efforts.

    Objective: To assess the role of computed tomography (CT) in the diagnosis of rib and lung involvement in tuberculous abscess in the retromammary region. Design and patients: Eight patients with tuberculous retromammary abscess were examined by CT and the findings were evaluated. A cold abscess (purulent collection with absence of acute inflammation) was aspirated in all cases. Diagnosis was confirmed by acid-fast bacillus culture, or histologic examination. Results: CT showed a relatively well marginated, inhomogeneous, hypodense lesions in all eight cases. Following administration of intravenous contrast medium, these lesions showed enhancing walls, suggestive of an infective collection. Lung involvement was seen in one patient. A direct communication from the retromammary lesion through the thoracic wall into the pleura was seen in five cases. In four cases destroyed rib fragments within the abscess were noted. Conclusion: A tuberculous abscess in the retromammary region is usually shown on CT as a focal, well-marginated, inhomogeneous, hypodense lesion with a surrounding enhancing rim. A direct communication with the pleura, a destroyed rib fragment in the abscess, and associated lung involvement may be revealed by CT. (orig.)

    A 49-year-old male who had been treated for pulmonary tuberculosis and tuberculous pleurisy in 2007 was referred to our hospital with the complaint of dyspnea on exertion in Nov. 2009. Chest X-ray showed increased pleural effusion compared with that remaining after the previous treatment of pleurisy in 2008. A chest CT revealed that fluid collection was surrounded by thickened pleura. Thoracocentesis was performed, and yellow milky liquid was obtained. The pleural effusion contained few cells. The triglyceride concentration was 83 mg/dl, and the cholesterol level was very high at 628 mg/dl. Based on these findings we diagnosed this case as chyliform pleural effusion. Both smear of acid-fast bacilli and PCR-TB test of the pleural effusion were positive, but culture was negative for mycobacterium, suggesting that this chyliform pleural effusion was produced by the former episode of tuberculous pleurisy, not by the recent reactivation of tuberculous pleurisy. The ADA concentration in the pleural effusion was high at 91.7 IU/l. No increase in the amount of pleural effusion was observed after thoracocentesis without any anti-tuberculosis therapy.

    Indonesia is the second country with the TB (tuberculosis) burden in the world. Improvement in controlling TB and reducing the complications can accelerate early diagnosis and correct treatment. PCR test is a gold standard. However, it is quite expensive for routine diagnosis. Therefore, an accurate and cheaper diagnostic method such as fine needle aspiration biopsy is needed. The study aimsto determine the accuracy of fine needle aspiration biopsy cytology in the diagnosis of tuberculous lymphadenitis. A cross-sectional analytic study was conducted to the samples from patients suspected with tuberculous lymphadenitis. The fine needle aspiration biopsy (FNAB)test was performed and confirmed by PCR test.There is a comparison to the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of both methods. Sensitivity (92.50%), specificity (96.49%), accuracy (94.85%), positive predictive value (94.87%) and negative predictive value (94.83%) were in FNAB test compared to gold standard. We concluded that fine needle aspiration biopsy is a recommendation for a cheaper and accurate diagnostic test for tuberculous lymphadenitis diagnosis.
