CT and MR images of 32 patients with neurocysticercosis were correlated with pathomorphology. Gross morphological features of cystic larvae, complex arachnoid cysts, granulomatous abscesses, basal meningitis and mineralised nodules correlated closely with the images obtained, especially on MR, where resolution permitted visualisation of larval protoscolices. Our material indicates three forms of the natural history of neurocysticercosis related chiefly to anatomic location, and provides details of the evolution of large, complex arachnoid cysts. (orig.)

Neurocysticercosis (NCC) is the most common parasitic infection of the nervous system. Considered a global epidemic, the parasite presents, mainly, as asymptomatic. Usually treatment is clinical, but in some selected cases surgical intervention is a good treatment option. In our case, keeping in view the magnitude of intracranial injury, surgery was the therapy chosen. A female patient, aged 54, Mulatto, native of Novo Cruzeiro (MG) and raised in Belo Horizonte. Presented with intense frontal headache, which progressed to right hemiparesis and seizure. Ten days after onset of symptoms, sought the service of emergency care. Tomography (CT) revealed a hypodense area in left frontoparietal region with characteristics of cystic lesion.

To evaluate MR imaging findings of degenerating parenchymal neurocysticercosis and to determine the characteristics which distinguish it from other brain diseases. MR imagings of 19 patients (56 lesions) of degenerating parenchymal neurocysticercosis were retrospectively evaluated, focusing on the size and location of lesions signal intensity patterns of cyst fluid and wall, the extent of the surrounding edema and features of contrast enhancement. Degenerating parenchymal neurocysticercosis was located in gray or subcortical while matter in 89.3% of 56 lesions (50/56) ; most of these (98.2%) were smaller than 2 cm in diameter. Cyst fluid signal was hyperintense relative to CSF on T1 and proton density weighted images (92.9%). A hypointense signal rim of the cyst wall was noted in the lesions on proton density (92.9%) and T2 weighted (98.2%) images, Surrounding edema was mostly mild. Peripheral rim enhancement was noted in all lesions, and this was frequently irregular and lobulated (67.9%) with a focal defect in the enhancing rim(41.1%). Findings which could be helpful in distinguishing degenerating parencymal neurocysticercosis from other brain diseases are as follows : small, superficial lesions ; hyperintense signal of the cyst fluid on T1 and proton density weighted images ; hypointense signal of the cyst wall on proton density and T2 weighted images ; relatively mild extent of surrounding edema, and peripheral rim enhancement which is frequently irregular and lobulated with a focal defect in the enhancing rim

Neurocysticercosis is the most frequent parasitic disease of the central nervous system. It is caused by the larvae of Taenia solium, which can affect different anatomical sites. In Spain there is an increasing prevalence mainly due to immigration from endemic areas. The extraparenchymal forms are less common, but more serious because they usually develop complications. Neuroimaging plays a major role in the diagnosis and follow-up of this disease, supported by serology and a compatible clinical and epidemiological context. First-line treatments are cysticidal drugs such as albendazole and praziquantel, usually coadministered with corticosteroids, and in some cases surgery is indicated. We here report a case of neurocysticercosis with simultaneous intraventricular and giant racemose subarachnoid involvement. Copyright © 2015 Asociación Argentina de Microbiología.

Full Text Available Pratibha Singhi, Arushi Gahlot SainiDepartment of Pediatrics, Pediatric Neurology and Neurodevelopment Unit, Advanced Pediatrics Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, IndiaAbstract: Neurocysticercosis (NCC is an acquired infection of the nervous system caused by encysted larvae of Taenia solium. It is a major cause of epilepsy in the tropics and the commonest cause of focal seizures in North Indian children. T. solium teniasis-cysticercosis is considered a parasitic “Neglected Tropical Diseases” endemic throughout Southeast Asia. NCC in children has pleomorphic manifestations depending on the location, number and viability of the cysts, and host response. Even with advancing knowledge of the disease manifestations, many aspects related to diagnosis and treatment, particularly in children, still remain controversial and pose challenges to clinical practice. There is no gold standard test to diagnose NCC and the management recommendations are still emerging. This review provides an overview of diagnosis of NCC in children and its management with special focus on current challenges and future prospects.Keywords: neurocysticercosis, children, epilepsy, ring enhancing lesions, pigs

Disseminated neurocysticercosis presenting as affective mood disorder with chronic tension type headache

Full Text Available Neurocysticercosis is a common parasitic infection in India presenting usually with seizues, headache, focal neurological deficits. Neurocysticercosis presenting as a psychiatric illness is rare. Disseminated cysticercosis with involvement of central nervous system and head and neck muscles is rare even in endemic areas. We present a case of disseminated cysticercosis, which presented with chronic tension type headache and affective mood disorder. Treatment with cysticidal drugs led to complete remission of psychiatric complaints. In endemic areas history suggestive of mood disorder should not be used as supportive evidence of a primary headache syndome like tension type headche without ruling out secondary causes. Making an early diagnosis can prevent morbidity.

Full Text Available Objective: To describe the clinical and epidemiological profile of patients diagnosed with neurocysticercosis at two hospitals in Chiclayo, Peru. Materials and methods: A descriptive, cross-sectional and retrospective study was performed at the Almanzor Aguinaga Asenjo Hospital and Lambayeque Regional Hospital. Ninety-six (96 medical records of patients attended in 2014 with a diagnosis of neurocysticercosis were reviewed. Results: The mean age of the patients was 42.8 ± 18.8 years old, 52.1% were female, 26% came from Chiclayo and 54.2% received care for the first time. The most common symptom leading to medical consultation was headache. All patients underwent a diagnostic imaging method. The location of the parasite was mostly in the brain and the calcified stage was the most common one. The most widely used treatments were anticonvulsants and pain relievers. Conclusions: Neurocysticercosis mainly affects the economically active population, is more common in women and the most common clinical manifestation is headache

Full Text Available Neurocysticercosis is the most common CNS parasitic disease but spinal presentation of this condition is rare, with a higher incidence in developing countries like ours. We report the case of a male patient 61 of age diagnosed with generalized neurocysticercosis in addition to the secondary presentation of hypertensive hydrocephalus and compression of the spinal cord, the latter is characterized by the appearance of paraparesis, changes in sensitivity and urinary retention. The final diagnosis was made by an MRI, so we have to emphasize the importance of neuroimaging in the definitive diagnosis of this disease.

Neurocysticercosis is a central nervous system parasitic infection caused by Taenia Solium whose clinical manifestations include seizures in 50-70% of patients, headache, intracranial hypertension and focal neurological deficits. Objective: To review the literature and to present imaging studies of two patients with the disease and classify its findings according to the pathologic stage. Methods: Review of literature and imaging of two patients with parenchymal neurocysticercosis using cranial computed tomography which showed cystic lesions at the gray-white junction associated with ring enhancement and some of them with surrounding edema; besides calcified granulomatous lesions. The documented findings represent the imaging spectrum of different parenchymal stages of neurocysticercosis. Conclusions: The cranial computed tomography is very helpful in diagnosis and monitoring neurocysticercosis.

Reversible dementia due to Neurocysticercosis: improvement of the racemose type with antihistamines

Directory of Open Access Journals (Sweden)

Gislaine Cristina Lopes Machado-Porto

Full Text Available Infection of the human central nervous system (CNS by the larvae of Taenia solium, termed neurocysticercosis (NCC, is endemic in most developing countries, where it is a major cause of acquired seizures and other neurological morbidity, including neuropsychiatric symptoms. However, despite its frequent manifestation, some findings, such as cognitive impairment and dementia, remain poorly understood. Less commonly, NCC may affect the ventricular system and subarachnoid spaces and this form is known as extraparenchymal neurocysticercosis. A particular presentation of the subarachnoid form is called racemose cysticercosis, which has a progressive pattern, frequently leads to hydrocephalus and can be life-threatening. Here we review a case of the racemose variety of cysticercosis, complicated by hydrocephalus and reversible dementia, with remission of symptoms after derivation and that remained stable with use of dexchlorpheniramine. We discuss the challenges in diagnosis, imaging findings, treatment and follow-up of this disease.

Neurocysticercosis as an important differential of seizures in pregnancy: two case reports

Directory of Open Access Journals (Sweden)

Singhal Suresh K

2011-05-01

Full Text Available Abstract Introduction Seizures in pregnancy usually result from eclampsia, epilepsy or central nervous system disorders. Neurocysticercosis is a rare, but an important, cause of first-time convulsions in pregnancy. Case presentations We report the cases of two Indian women, aged 20 and 24 years old respectively, with neurocysticercosis presenting in the second trimester of pregnancy with convulsions. Both had marginally raised blood pressure with 1+ urine albumin and neither had a past history of convulsions. The neurocysticercosis was diagnosed on magnetic resonance imaging of the head, which showed spherical ring-enhancing lesions in the brain. In one woman, pregnancy was terminated due to spina bifida in the fetus and she was discharged on albendazole and phenytoin. The second woman was put on carbamazepine: she had an emergency Cesarean section at term for fetal distress and delivered a healthy baby. Her postnatal period was uneventful. Conclusion Neurocysticercosis should be considered in pregnant women presenting with seizures which cannot be explained by eclampsia, especially in early pregnancy.

Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5%). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.

Aims Albendazole (ABZ) is effective in the treatment of neurocysticercosis. ABZ undergoes extensive metabolism to (+) and (−)-albendazole sulphoxide (ASOX), which are further metabolized to albendazole sulphone (ASON). We have investigated the distribution of (+)-ASOX (−)-ASOX, and ASON in cerebrospinal fluid (CSF) of patients with neurocysticercosis. Methods Twelve patients with a diagnosis of active brain parenchymal neurocysticercosis treated with albendazole for 8 days (15 mg kg−1 day−1) were investigated. On day 8, serial blood samples were collected during the dose interval (0–12 h) and one CSF sample was taken from each patient by lumbar puncture at different time points up to 12 h after the last albendazole dose. Albendazole metabolites were determined in CSF and plasma samples by h.p.l.c. using a Chiralpak AD column and fluorescence detection. Population curves for CSF albendazole metabolite concentration vs time were constructed. Results The mean plasma/CSF ratios were 2.6 (95% CI: 1.9, 3.3) for (+)-ASOX and 2.7 (95% CI: 1.8, 3.7) for (−)-ASOX, with the two-tailed P value of 0.9873 being non-significant. These data indicate that the transport of ASOX through the blood–brain barrier is not enantioselective, but rather depends on passive diffusion. The present results suggest the accumulation of the (+)-ASOX metabolite in the CSF of patients with neurocysticercosis. The CSF AUC(+)/AUC(−) ratio was 3.4 for patients receiving albendazole every 12 h. The elimination half-life of both ASOX enantiomers in CSF was 2.5 h. ASOX was the predominant metabolite in the CSF compared with ASON; the CSF AUCASOX/AUCASON ratio was approximately 20 and the elimination half-life of ASON in CSF was 2.6 h. Conclusions We have demonstrated accumulation of the (+)-ASOX metabolite in CSF, which was about three times greater than the (−) antipode. ASOX concentrations were approximately 20 times higher than those observed for the ASON metabolite. PMID:12207631

Full Text Available OBJECTIVE: The purpose of this paper was to investigate the role of two three-dimensional magnetic resonance (MRI sequences: enhanced spoiled gradient recalled echo (SPGR, and fast imaging employing steady-state acquisition (FIESTA in the evaluation of intraventricular neurocysticercosis cysts and scolices. METHOD: Seven neurocysticercosis patients suspected of presenting intraventricular lesions were evaluated by magnetic resonance imaging using enhanced SPGR, and FIESTA. RESULTS: Enhanced SPGR detected eight cystic lesions, with scolices in four. Contrast enhancement was observed in three cysts. FIESTA also detected eight cystic lesions with the presence of scolices in seven of those cystic lesions. Four patients presented parenchymal involvement, while the remaining three presented the racemose form. CONCLUSION: FIESTA and SPGR are sequences that can detect intraventricular cysts of neurocysticercosis, and FIESTA also is good for the detection of the scolex. Considering this information we suggest that FIESTA and SPGR should be included in the MRI protocol for the investigation of intraventricular neurocysticercosis.

A male patient with neurocysticercosis was identified in Montai Village, Xay District, Oudomxay Province, Lao PDR in February 2004. He had a history of diagnosis for neurocysticercosis by a CT scan in Thailand after an onset of epileptic seizure in 1993. A pig in the same district was found to contain Taenia solium metacestodes (=cysticerci); the slaughtered pig body contained more than 2,000 cysticerci. In addition to morphological identification, molecular identification was also performed on the cysticerci by DNA sequencing analysis of the mitochondrial cox1 gene; they were confirmed as T. solium metacestodes. The patient is regarded as an indigenous case of neurocysticercosis infected in an endemic focus of T. solium taeniasis/cysticercosis in Oudomxay Province, Lao PDR.

Full Text Available Neurocysticercosis (NCC is the most common single cause of seizures/epilepsy in India and several other endemic countries throughout the world. It is also the most common parasitic disease of the brain caused by the cestode Taenia solium or pork tapeworm. The diagnosis of NCC and the tapeworm carrier (taeniasis can be relatively inaccessible and expensive for most of the patients. In spite of the introduction of several new immunological tests, neuroimaging remains the main diagnostic test for NCC. The treatment of NCC is also mired in controversy although, there is emerging evidence that albendazole (a cysticidal drug may be beneficial for patients by reducing the number of seizures and hastening the resolution of live cysts. Currently, there are several diagnostic and management issues which remain unresolved. This review will highlight some of these issues.

Full Text Available Extraparenchymal neurocysticercosis (ExPNCC, an infection caused by Taenia solium cysticerci that mainly occurs in the ventricular compartment (Ve or the basal subarachnoid space (SAb, is more severe but less frequent and much less studied than parenchymal neurocysticercosis (ParNCC. Demographic, clinical, radiological, and lumbar cerebrospinal fluid features of patients affected by ExPNCC are herein described and compared with those of ParNCC patients.429 patients with a confirmed diagnosis of neurocysticercosis, attending the Instituto Nacional de Neurología y Neurocirugía, a tertiary reference center in Mexico City, from 2000 through 2014, were included. Demographic information, signs and symptoms, radiological patterns, and lumbar cerebrospinal fluid (CSF laboratory values were retrieved from medical records for all patients. Data were statistically analyzed to assess potential differences depending on cyst location and to determine the effects of age and sex on the disease presentation. In total, 238 ExPNCC and 191 ParNCC patients were included. With respect to parenchymal cysts, extraparenchymal parasites were diagnosed at an older age (P = 0.002, chiefly caused intracranial hypertension (P < 0.0001, were more frequently multiple and vesicular (P < 0.0001, and CSF from these patients showed higher protein concentration and cell count (P < 0.0001. SAb patients were diagnosed at an older age than Ve patients, and showed more frequently seizures, vesicular cysticerci, and higher CSF cellularity. Gender and age modulated some traits of the disease.This study evidenced clear clinical, radiological, and inflammatory differences between ExPNCC and ParNCC, and between SAb and Ve patients, and demonstrated that parasite location determines different pathological entities.

Cysticercosis, once rare in Australia, is now more frequently diagnosed. This change reflects the countries of origin of new immigrants and the destinations of Australians travelling. Five cases of neurocysticercosis diagnosed at Westmead Hospital in Sydney are described. Two involved Australians, a father and son who had visited eastern and southeastern Asia 10 years before presentation. The other three included immigrants from Chile and India and a visitor from Timor. Ages ranged from 5 to 57 years. Three individuals presented after focal seizures involving the upper limb, one had a long standing history of neurological dysfunction and one suffered from persistent headaches. In all cases computed tomographic scanning (CT) or magnetic resonance imaging (MRI) revealed cystic brain lesions and three of the five were seropositive as well. Four were treated with praziquantel and in one the lesions regressed significantly following treatment. However, the lesion in one case had decreased in size prior to treatment and that in the untreated individual also became smaller.

Neurocysticercosis (NCC) is a major cause of neurological morbidity in the developing world. This study aimed to assess the treatment costs and productivity losses associated with NCC in Peru. NCC patients were identified through retrospective chart analysis. Patients meeting inclusion criteria were interviewed in order to obtain data on symptom history, treatment costs, productivity losses and health service utilisation patterns. These data were modelled to determine average treatment costs and productivity losses over 2 years. Our findings show that treatment costs and productivity losses consume 54% of an annual minimum wage salary during the first year of treatment and 16% during the second year. Diagnosis (36%) and drug therapy (27%) represent the most expensive healthcare-related costs. These costs are prohibitive for some-8% of our study sample had no diagnostic tests during their first 6 months of disease, and two-thirds of those who delayed treatment reportedly did so due to their inability to pay. Two-thirds of wage-earners lost their jobs owing to NCC and only 61% were able to re-engage in wage-earning activities. This study highlights the need to expand financial coverage to ensure the poor have access to health services and do not become further impoverished.

Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographs (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e. 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact neurocysticercosis is a more frequent disease than indicated by the few diagnoses made. (author)

Full Text Available Cysticidal treatment of neurocysticercosis, an infection of humans and pig brains with Taenia solium, results in an early inflammatory response directed to cysts causing seizures and focal neurological manifestations. Treatment-induced pericystic inflammation and its association with blood brain barrier (BBB dysfunction, as determined by Evans blue (EB extravasation, was studied in infected untreated and anthelmintic-treated pigs. We compared the magnitude and extent of the pericystic inflammation, presence of EB-stained capsules, the level of damage to the parasite, expression of genes for proinflammatory and regulatory cytokines, chemokines, and tissue remodeling by quantitative PCR assays between treated and untreated infected pigs and between EB-stained (blue and non stained (clear cysts. Inflammatory scores were higher in pericystic tissues from EB-stained cysts compared to clear cysts from untreated pigs and also from anthelmintic-treated pigs 48 hr and 120 hr after treatment. The degree of inflammation correlated with the severity of cyst wall damage and both increased significantly at 120 hours. Expression levels of the proinflammatory genes for IL-6, IFN-γ, TNF-α were higher in EB-stained cysts compared to clear cysts and unaffected brain tissues, and were generally highest at 120 hr. Additionally, expression of some markers of immunoregulatory activity (IL-10, IL-2Rα were decreased in EB-stained capsules. An increase in other markers for regulatory T cells (CTLA4, FoxP3 was found, as well as significant increases in expression of two metalloproteases, MMP1 and MMP2 at 48 hr and 120 hr post-treatment. We conclude that the increase in severity of the inflammation caused by treatment is accompanied by both a proinflammatory and a complex regulatory response, largely limited to pericystic tissues with compromised vascular integrity. Because treatment induced inflammation occurs in porcine NCC similar to that in human cases, this model

Neurocysticercosis (NCC) is the most frequent parasitic illness of the central nervous system caused by the larval form of Taenia solium and its considered to be endemic in Latin America. Its diagnosis is based on imaging findings and epidemiological data; although its diagnosis can be made through the detection of specific IgG antibodies, these tests have limited availability in our environment. Central nervous system involvement is generally observed in the brain parenchyma, and less commonly in the ventricular system and subarachnoid space; only infrequently is reported to involve the structures within the spinal canal, in this article we review a case of a patient with spinal cysticercal involvement.

A survey was conducted in the urban area of Lages using patients who had been submitted to a computed tomography of the skull in the period of March-December, 1996, for different reasons. Forty-two patients with a provisional diagnosis of neurocysticercosis, and 57 negatives were personally interviewed by one of the authors (Pfuetzenreiter), using a semi-structured procedure. More individuals with a provisional diagnostic of neurocysticercosis reported clinical manifestations related to this infection than those found negative. this difference is more marked among women, except in relation to convulsions, more frequently reported by men (19.05%) than by women (7.14%). The greater percentage of inactive forms (83.33%0 and a longer history of perceived symptoms among those positives suggest that the condition is not new. (author)

To establish the method of two-dimensional differential gel electrophoresis and obtain high resolution 2D images from cerebrospinal fluid (CSF) of patients with neurocysticercosis. CSF samples were collected from four patients diagnosed as neurocysticercosis clinically and by ELISA, computed tomography (CT) or magnetic resonance imaging (MRI), and from four healthy subjects without neurological disorders. The CSF samples were precipitated with cold acetone, then pooled by equal amount as patients and controls. The internal standard comprised equal amounts of proteins extracted from both groups. Internal standard, and proteins from the two groups were labeled prior to electrophoresis with spectrally resolvable fluorescent dyes, cyanein dye2 (Cy2), Cy3 and Cy5. Sodium dodecylsulfonate polyacrylamide gel chromatography (SDS-PAGE) and two-dimensional differential in-gel electrophoresis (2-D DIGE) of labeled samples were then run. The differential expressed proteins showed in the images of SDS-PAGE and 2-D DIGE gels scanned with 488 nm, 532 nm and 633 nm wavelength laser were analyzed by ImageQuant and DeCyde 5.0 respectively. Spot detection and quantification was performed for the differential in-gel analysis (DIA) module of DeCyder. Biological variation analysis (BVA) module of DeCyder was matched gel 1 and gel 2 images to provide data on differential protein expression levels between the two groups. The ImageQuant result displayed that the CSF protein was compatible with the dye, and the difference of protein amount was revealed by the difference of fluorescence intensity. DIA indicated that there were 896 and 894 protein dots on gel 1 and gel 2 respectively, and 90% of them were matched each other. BVA showed that there were 55 protein spots with different expressional level between neurocysticercosis and control groups. Protein spots with two-fold increase or decrease were 47 and 8 respectively in neurocysticercosis patients compared with healthy controls. The

Clinical presentation of neurocysticercosis-related epilepsy.

Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system and a major risk factor for seizures and epilepsy. Seizure types in NCC vary largely across studies and seizure semiology is poorly understood. We discuss here the studies regarding seizure types and seizure semiology in NCC, and examine the clinical presentation in patients with NCC and drug-resistant epilepsy. We also provide evidence of the role of MRI and EEG in the diagnosis of NCC-related epilepsy. Focal seizures are reported in 60-90% of patients with NCC-related epilepsy, and around 90% of all seizures registered prospectively are focal not evolving to bilateral tonic-clonic seizures. A great number of cases suggest that seizure semiology is topographically related to NCC lesions. Patients with hippocampal sclerosis and NCC have different clinical and neurophysiological characteristics than those with hippocampal sclerosis alone. Different MRI protocols have allowed to better differentiate NCC from other etiologies. Lesions' stages might account on the chances of finding an interictal epileptiform discharge. Studies pursuing the seizure onset in patients with NCC are lacking and they are specially needed to determine both whether the reported events of individual cases are seizures, and whether they are related to the NCC lesion or lesions.

Full Text Available Neurocysticercosis, the most common parasitic infection of the nervous system, is known to affect the brain, eyes, muscular tissues and subcutaneous tissues. However, it is very rare for patients with ocular cysts to have concomitant cerebral cysts. Also, the dominant clinical manifestation of patients with cerebral cysts is either seizures or headache. We report a patient who presented with acute monocular painless vision loss due to intraocular submacular cysticercosis, who on investigation had multiple cerebral parenchymal cysticercal cysts, but never had any seizures. Although such a vision loss after initiation of antiparasitic treatment has been mentioned previously, acute monocular vision loss as the presenting feature of ocular cysticercosis is rare. We present a brief review of literature along with this case report.

Neurocysticercosis caused by infection with Taenia solium is a significant cause of epilepsy and seizures in humans. The aim of this study was to assess the association between seizures and the deposition of collagen in brain tissue in pigs with T. solium neurocysticercosis. In total 78 brain tissue sections from seven pigs were examined histopathologically i.e. two pigs with epileptic seizures and T. solium cysts, four pigs without seizures but with cysts, and one non-infected control pig. Pigs with epileptic seizures had a larger amount of collagen in their brain tissue, showing as large fibrotic scars and moderate amount of collagen deposited around cysts, compared to pigs without seizures and the negative control pig. Our results indicate that collagen is likely to play a considerable part in the pathogenesis of seizures in T. solium neurocysticercosis. Copyright © 2016 The Authors. Published by Elsevier B.V.

Routine drug and food interactions during antihelminthic treatment of neurocysticercosis: a reason for the variable efficacy of albendazole and praziquantel?

Romo, Matthew L; Carpio, Arturo; Kelvin, Elizabeth A

2014-04-01

Neurocysticercosis (NC) or infection of the central nervous system with Taenia solium larvae is a leading cause of preventable seizures and epilepsy in endemic regions across the globe. Albendazole and praziquantel are commonly used antihelminthic agents to treat NC; however, viable cysts persist in the majority of patients, putting them at risk for future seizures and other neurological complications. Because of their pharmacokinetic profiles, albendazole and praziquantel have the potential to interact with many different drugs. During antihelminthic treatment, antiepileptic drugs and corticosteroids are commonly co-administered to manage seizures and cerebral edema; however, the most commonly used agents from these drug classes are known to significantly alter plasma concentrations of albendazole and praziquantel. The overarching issue with drug interactions during the treatment of NC is whether or not they have clinical relevance, as the plasma concentrations of albendazole and praziquantel have not been directly linked with eradication of viable cysts. Future studies should attempt to evaluate the validity of a causal relationship between antihelminthic plasma concentrations and outcomes so that drug interactions can be better understood and managed and so that treatment can be optimized. © 2014, The American College of Clinical Pharmacology.

The relationship between neurocysticercosis and epilepsy: an endless debate

Directory of Open Access Journals (Sweden)

Arturo Carpio

2014-05-01

Full Text Available Neurocysticercosis (NC, or cerebral infection with Taenia solium, is an important public health problem worldwide. Among the neurological sequelae of NC, seizures have been described as the most common symptom. Acute symptomatic seizures often result from degeneration of a viable cyst; however, not all of these patients with acute or provoked seizures will develop epilepsy (i.e., recurrent unprovoked seizures. Because of the high prevalence of epilepsy and NC, a causal, as well as incidental relationship between the two may exist. The epileptogenicity of calcified cysts as well as the potential association between NC and hippocampal sclerosis necessitates future research. Antihelminthic treatment of NC results in disappearance of viable cysts in about one-third of patients with parenchymal disease, but a reduction in seizure recurrence has not been demonstrated in randomized controlled trials. Prevention is critical to reduce the burden of seizure and epilepsy related to NC.

Late onset temporal lobe epilepsy with MRI evidence of mesial temporal sclerosis following acute neurocysticercosis. Case report

2001-01-01

The objective of this case report is to describe magnetic resonance imaging (MRI) evidence of mesial temporal sclerosis (MTS) in a patient with new onset temporal lobe epilepsy (TLE) and acute neurocysticercosis with multiple cysts. A 56 years old man with new onset headache, Simple Partial Seizures and Complex Partial Seizures underwent CT scan and lumbar puncture as diagnose proceeding. Multiple cysts and meningitis were identified, with a positive immunology for cysticercosis. Seizures were recorded over the left temporal region in a routine EEG. Treatment with al bendazole was performed for 21 days, with clinical improvement and seizure remission after 4 months. An MRI scan 11 months after treatment, showed complete resolution of those cystic lesions and a left hippocampal atrophy (HA) with hyperintense T2 signal. The presence of HA and hyperintense T 2 signal in this patient has not, to date, been associated with a poor seizure control. Conclusions: This patient presented with MRI evidence of left MTS after new onset partial seizures of left temporal lobe origin. Although we did not have a previous MRI scan, it is likely that this hippocampal abnormality was due to the acute inflammatory response to cysticercosis associated to repeated partial seizures. This suggests that acute neurocysticercosis associated with repeated seizures may cause MTS and late onset TLE. (author)

Aside from brain injury and genetic causes, there is emerging information on brain infection and inflammation as a common cause of epilepsy. Neurocysticercosis (NCC), the most common cause of epilepsy worldwide, is caused by brain cysts from the Taenia solium tapeworm. In this article, we provide a critical analysis of current and emerging information on the relationship between NCC infection and epilepsy occurrence. We searched PubMed and other databases for reports on the prevalence of NCC and incidence of epilepsy in certain regions worldwide. NCC is caused by brain cysts from the T. solium and related tapeworms. Many people with NCC infection may develop epilepsy but the rates are highly variable. MRI imaging shows many changes including localization of cysts as well as the host response to treatment. Epilepsy, in a subset of NCC patients, appears to be due to hippocampal sclerosis. Serologic and brain imaging profiles are likely diagnostic biomarkers of NCC infection and are also used to monitor the course of treatments. Limited access to these tools is a key limitation to identify and treat NCC-related epilepsy in places with high prevalence of this parasite infestation. Overall, NCC is a common infection in many patients with epilepsy worldwide. Additional clinical and animal studies could confirm common pathology of NCC as a postinfectious epilepsy that is curable.

Neurocysticercosis in a 14-year-old boy in Italy: An unexpected case

Directory of Open Access Journals (Sweden)

2013-08-01

Full Text Available Neurocysticercosis (NCC is a parasitic infection of the central nervous system caused by larvae of Taenia solium. It represents the most common cause of neurological disease in children living in developing countries. In recent years, NCC is increasingly being diagnosed also in high-socioeconomic countries, mainly due to the high rate of immigration. We describe a case of a 14-year-old Ecuadorian boy living in Italy, who experienced a generalized tonic-clonic seizure and was diagnosed with NCC. The boy was successfully managed with anticonvulsant, anticysticercal and anti-inflammatory treatment. With the present case we would like to emphasize the importance of considering NCC as a possible cause of non febrile seizures in children living in developed countries, particularly in those immigrated from an endemic region or had a long-term stay in an area of high prevalence.

Repeated peritoneal catheter blockage caused by neurocysticercosis following ventriculoperitoneal shunt placement for hydrocephalus

Directory of Open Access Journals (Sweden)

Zhi Hua Li

2018-01-01

Full Text Available Cerebral cysticercosis is common, but the possibility for repeated occurrence of peritoneal catheter blockage caused by neurocysticercosis (NCC after two revisions following ventriculoperitoneal shunt placement for hydrocephalus is unusual. Herein, we describe one rare case in which peritoneal catheter revision was performed two times unsuccessfully. Endoscopic cysternostomy rather than peritoneal catheter adjustment was performed successfully, and histopathological examination of excised cystic samples confirmed NCC in our hospital. The present case highlights the need for awareness of NCC as a possible etiology of hydrocephalus, especially in developing countries. Uncommon findings in both lateral ventricles following low-field magnetic resonance imaging scans as well as the rarity of this infection involved in unusual location play important roles in misdiagnosis and incorrect treatment for hydrocephalus; thus, endoscopic cysternostomy, rather than multiple shunt adjustment of the peritoneal end, is recommended in the selected patient. To the best of our knowledge, this is the first report describing the misdiagnosis and inappropriate treatment of hydrocephalus caused by cerebral cysticercosis in China.

Neurocysticercosis is an endemic parasitic disease caused by Taenia solium larva. Although the mechanism of infection is not completely understood, it is likely driven by proteolytic activity that degrades the intestinal wall to facilitate oncosphere penetration and further infection. We analyzed the publicly available T. solium EST/DNA library and identified two contigs comprising a full-length cDNA fragment very similar to Echinococcus granulosus Ag5 protein. The T. solium cDNA sequence included a proteolytic trypsin-like-domain in the C-terminal region, and a thrombospondin type-1 adherence-domain in the N-terminal region. Both the trypsin-like and adherence domains were expressed independently as recombinant proteins in bacterial systems. TsAg5 showed marginal trypsin-like activity and high sequence similarity to Ag5. The purified antigens were tested in a Western immunoblot assay to diagnose human neurocysticercosis. The sensitivity of the trypsin-like-domain was 96.36% in patients infected with extraparenchymal cysts, 75.44% in patients infected with multiple cysts, and 39.62% in patients with a single cyst. Specificity was 76.70%. The thrombospondin type-1 adherence-domain was not specific for neurocysticercosis. Copyright © 2011 Elsevier B.V. All rights reserved.

Neurocysticercosis (NCC), Taenia solium larval infection of the brain, is an important cause of acquired seizures in endemic countries, which relate to number, location and degenerating cysts in the brain. Multicyst infections are common in endemic countries although single-cyst infection prevails in India. Single-cyst infections in an endemic country suggest a role for host immunity limiting the infection. This study examined ex vivo CD4(+) T cells and in vitro Th1 and Th2 cytokine responses to T. solium cyst antigens of peripheral blood mononuclear cells of healthy subjects from endemic and nonendemic regions and of single- and multicyst-infected patients for association with cyst burden of NCC. T. solium cyst antigens elicited a Th1 cytokine response in healthy subjects of T. solium-endemic and T. solium-non-endemic regions and those with single-cyst infections and a Th2 cytokine response from subjects with multicyst neurocysticercosis. Multicyst neurocysticercosis subjects also exhibited low levels of effector memory CD4(+) T cells. Th1 cytokine response of T. solium exposure and low infectious loads may aid in limiting cyst number. Th2 cytokines and low effector T cells may enable multiple-cyst infections to establish and persist. © 2016 John Wiley & Sons Ltd.

Albendazole metabolism in patients with neurocysticercosis: antipyrine as a multifunctional marker drug of cytochrome P450

Full Text Available The present study investigates the isoform(s of cytochrome P450 (CYP involved in the metabolism of albendazole sulfoxide (ASOX to albendazole sulfone (ASON in patients with neurocysticercosis using antipyrine as a multifunctional marker drug. The study was conducted on 11 patients with neurocysticercosis treated with a multiple dose regimen of albendazole for 8 days (5 mg/kg every 8 h. On the 5th day of albendazole treatment, 500 mg antipyrine was administered po. Blood and urine samples were collected up to 72 h after antipyrine administration. Plasma concentrations of (+-ASOX, (--ASOX and ASON were determined by HPLC using a chiral phase column and detection by fluorescence. The apparent clearance (CL/f of ASON and of the (+ and (--ASOX enantiomers were calculated and compared to total antipyrine clearance (CL T and the clearance for the production of the three major antipyrine metabolites (CLm. A correlation (P<=0.05 was obtained only between the CL T of antipyrine and the CL/f of ASON (r = 0.67. The existence of a correlation suggests the involvement of CYP isoforms common to the metabolism of antipyrine and of ASOX to ASON. Since the CL T of antipyrine is a general measure of CYP enzymes but with a slight to moderate weight toward CYP1A2, we suggest the involvement of this enzyme in ASOX to ASON metabolism in man. The study supports the establishment of a specific marker drug of CYP1A2 in the study of the in vivo metabolism of ASOX to ASON.

The prevalence of epilepsy was 2.04% (P and 2.25% (T. The prevalence of neurocysticercosis was 0.47% (P and 0.93% (T, and prevalence of swine cysticercosis was 12.8% (P and 27.8% (T. Taenia sp. infestation wis detected in 4.3% (P and 4.6% (T of stool examinations. The hyperendemic human taeniasis and cysticercosis and swine cysticercosis seems to be related to poor hygienic habits of the population, and the free access to human excreta by the pigs.

Full Text Available Aim: The prevalence of epilepsy is higher in Nepal. This study was conducted to analyze the clinical manifestations of neurocysticercosis (NCC among seizure patients admitted to our center. Methods: We retrospectively studied all the NCC patients admitted to Neurology Department, Bir Hospital, Kathmandu, Nepal from April 2012 to February 2014. Computer tomography/magnetic resonance imaging (CT/MRI head, clinical profile, lab investigations and exclusion of other causes were the basis of the NCC diagnosis. Chi-square and Student′s t-test were used for comparison of variables. Results: Out of 131 seizure patients admitted, 21 patients were diagnosed with NCC (mean age: 33.95 ± 16.41; male: 15 (71.4%, female: 6 (28.6%. Generalized tonic clonic seizure was the most common seizure type in NCC patients (18 patients; 85.7%, two of them had status epilepticus during presentation in Emergency Department. Three patients had focal seizure, one with epilepsia partialis continua. Neuroimaging showed multiple NCC lesions in 8 (38.1% and a single NCC lesion in 13 (61.9% patients. Seven of them (33.3% sought traditional healers before being presented to our center. Eight patients (38.1% were treated with antiepileptics in local health-post without neuroimaging studies done. Calcified stage of NCC was the most frequent CT/MRI findings (12 patients; 57.1%. Phenytoin was preferred both by physicians and patients due to its low cost. Conclusion: NCC is a common finding among seizure patients in Nepal. Poor economic status, illiteracy and underdeveloped rural society are the major challenges in prevention and treatment of NCC.

Full Text Available OBJECTIVE: To evaluate the performance of two antigenic preparations (vesicular fluid - VF and a glycoprotein fraction, LLa-Gp fraction, purified from a whole parasite extract by lentil lectin affinity chromatography from Taenia solium cysticerci for the immunodiagnosis of neurocysticercosis. METHOD: Fifty-six cerebrospinal fluid (CSF samples (22 from patients with neurocysticercosis and 34 from patients with other neurological disorders and 57 serum samples (22 from patients with neurocysticercosis, 18 from patients with other infections and 17 from presumably healthy persons were assayed for anticysticercal IgG antibodies with an enzyme-linked immunosorbent assay (ELISA. RESULTS: The VF ELISA showed 100% sensitivity and specificity in CSF and serum samples, whereas the sensitivity and specificity of the LLa-Gp ELISA were, respectively, 90.9% and 97.1%, with the CSF samples and 95.5% and 100% with serum samples. There was no significant difference in the sensitivity and specificity of the two antigenic preparations used to screen CSF and serum samples. CONCLUSION: Considering the complexity and high cost of obtaining the LLa-Gp fraction, VF could be more suitable for screening specific antibodies by ELISA in CSF and serum samples from patients with neurocysticercosis.

A survey was conducted in the urban area of Lages using patients who had been submitted to a computed tomography of the skull in the period of March-December, 1996, for different reasons. Forty-two patients with a provisional diagnosis of neurocysticercosis, and 57 negatives were personally interviewed by one of the authors (Pfuetzenreiter), using a semi-structured procedure. More individuals with a provisional diagnostic of neurocysticercosis reported clinical manifestations related to this infection than those found negative. this difference is more marked among women, except in relation to convulsions, more frequently reported by men (19.05%) than by women (7.14%). The greater percentage of inactive forms (83.33%0 and a longer history of perceived symptoms among those positives suggest that the condition is not new. (author)

To assess the prevalence of Taenia solium cysticercosis in patients with neurological disorders in Slovenia, serum/cerebrospinal fluid (CSF) samples from 348 suspected patients were collected between the beginning of January 2001 and the end of December 2012 and analysed serologically for the presence of anti-T. solium IgG antibodies. Of 20 patients whose samples tested positive or equivocal by enzyme-linked immunosorbent assay (ELISA), samples of 7 patients were confirmed positive by Western blot (WB). The overall seroprevalence rate of T. solium infection in patients with neurological disorders included in the study was 2.0%. Serological results of positive patients corresponded to clinical and/or imaging findings concerning their brain cysts. Based on their personal data, it was ascertained that neurocysticercosis (NCC) positive patients had immigrated or came to Slovenia from the former Yugoslav republics. Since the disease is believed not to be endemic in Slovenia we assume that all of the NCC-positive patients had acquired the infection before immigration to Slovenia or visiting or being visited by their relatives infected with an adult T. solium parasite. The present results represent the first insight into the prevalence of NCC in patients with neurological disorders in Slovenia.

Full Text Available Neurocysticercosis (NCC is one of the major causes of childhood seizures in developing countries including India and Latin America. In this study neurological pediatric cases presenting with afebrile seizures were screened for anti-Cysticercus antibodies (IgG in their sera in order to estimate the possible burden of cysticercal etiology. The study included a total of 61 pediatric afebrile seizure subjects (aged one to 15 years old; there was a male predominance. All the sera were tested using a pre-evaluated commercially procured IgG-ELISA kit (UB-Magiwell Cysticercosis Kit ™. Anti-Cysticercus antibody in serum was positive in 23 of 61 (37.7% cases. The majority of cases with a positive ELISA test presented with generalized seizure (52.17%, followed by complex partial seizure (26.08%, and simple partial seizure (21.73%. Headaches were the major complaint (73.91%. Other presentations were vomiting (47.82%, pallor (34.78%, altered sensorium (26.08%, and muscle weakness (13.04%. There was one hemiparesis case diagnosed to be NCC. In this study one child without any significant findings on imaging was also found to be positive by serology. There was a statistically significant association found between the cases with multiple lesions on the brain and the ELISA-positivity (p = 0.017. Overall positivity of the ELISA showed a potential cysticercal etiology. Hence, neurocysticercosis should be suspected in every child presenting with afebrile seizure especially with a radio-imaging supportive diagnosis in tropical developing countries or areas endemic for taeniasis/cysticercosis.

Role of chemotherapy of taeniasis in prevention of neurocysticercosis.

Pawlowski, Zbigniew S

2006-01-01

Neurocysticercosis (NC) is a serious public health problem in Taenia solium endemic areas and in some immigrants and international travelers. A key intervention in preventing NC is elimination of taeniasis by chemotherapy. Currently, two safe and effective taenicides, namely niclosamide and praziquantel, are available. Both are on WHO Essential Drug list, but are often inaccessible in T. solium endemic areas. Natural remedies, still widely used in some endemic areas, are frequently carcinogenic or highly toxic and as such should be discontinued. Chemotherapeutic intervention to control T. solium taeniasis/cysticercosis, whilst theoretically feasible, has several practical obstacles. These include poor public awareness, problems with diagnosing Taenia carriers, poor availability of taenicides where needed and low priority afforded to the control of NC. These can be overcome, respectively, by effective health education, wider use of newly developed coproantigen tests, strengthening of health services infrastructure and essential drugs distribution, and increasing the priority given to prevention of NC, as a leading cause of epilepsy in T. solium endemic areas. Information is accumulating on rational approaches to population-based short-term chemotherapeutic control measures. These are: widely available modern diagnostic tools and taenicides, treatment of any case of taeniasis, confirmed or probable, focus-oriented chemotherapy, irrespective of Taenia species implicated, improved sanitation, cooperation of veterinary and medical services, linkage with programs against epilepsy and cooperation of better educated communities. Now, it remains to take an advantage of existing tools and experience.

To estimate annual costs related to the diagnosis, treatment and productivity losses among patients with neurocysticercosis (NCC) receiving treatment at two referral hospitals, the Instituto Nacional de Neurologia y Neurocirugia (INNN) and the Hospital de Especialidades of the Instituto Mexicano del Seguro Social (HE-IMSS), in Mexico City from July 2007 to August 2008. Information on presenting clinical manifestations, diagnostic tests, hospitalisations, surgical procedures and other treatments received by NCC outpatients was collected from medical charts, and supplemented by an individual questionnaire regarding productivity losses and out-of-pocket expenses related to NCC. The annual average per-patient direct costs were US$ 503 (95% CI: 414-592) and US$ 438 (95% CI: 322-571) for patients without a history of hospitalisation and/or surgery seen at the INNN and the HE-IMSS, respectively. These costs increased to US$ 2506 (95% CI: 1797-3215) and US$ 2170 (95% CI: 1303-3037), respectively, for patients with a history of hospitalisation and/or surgery. The average annual per-patient indirect costs were US$ 246 (95% CI: 165-324) and US$ 114 (95% CI: 51-178), respectively, using minimum salary wages for individuals not officially employed. The total annual cost for patients who had and had not been hospitalised and/or undergone a surgical procedure for the diagnosis or treatment of NCC corresponded to 212% and 41% of an annual minimum wage salary, respectively. The disease tends to affect rural socioeconomically disadvantaged populations and creates health disparities and significant economic losses in Mexico. © 2015 John Wiley & Sons Ltd.

2007-12-01

Taenia solium is the commonest parasitic infection of CNS and an important cause of new-onset seizures and epilepsy in children and adults. Human activities impact on almost every one of the stages of the lifecycle of the worm as man is responsible for dispersion of the parasite's egg through outdoor defecation and indiscriminate disposal of feces. Health education to cause behavioral changes in these practices can therefore be an effective intervention strategy. We conducted a study to assess KAP regarding taeniasis and neurocysticercosis among municipal school teachers in Delhi. The findings are presented in this communication. The study revealed that, general information related to personal food hygiene was known to majority of the teachers but core information in the context of taeniasis/cysticercosis and seizure prevention was lacking.

Full Text Available We studied 32 rural patients from the poorest regions in South Africa, diagnosed as epilepsy due to neurocysticercosis presenting pseudoseizures. We found that the common clinical characteristics of this series and its psychological profile such as: duration of events, history of sexual abuse in females, absent of focal neurological signs, vocalization in the middle of the seizures, and lack of post-ictal symptoms were very useful for its differential diagnosis, and the possible difference between the clinical features and psychological profile of those patients and others without PS. Finally, some advices for the management of this condition by family doctors are suggested. ______________ RESUMEN: Estudiamos 32 pacientes provenientes de las áreas rurales mas pobres de Sudáfrica en los cuales se diagnosticó una epilepsia secundaria a neurocisticercosis cerebral y que además presentaban seudo crisis epilépticas. Encontramos un número de características clínicas y psicológicas comunes en este grupo tales como la duracion de las crisis, historia de abuso sexual en las hembras, ausencia de signos neurológicos focales, vocalización en el intervalo entre las crisis y la falta de signos postictales que resultó ser muy útil en el diagnóstico diferencial. Se encontraron además diferencias en las características clínicas y psicológicas estos pacientes con relación a otros que no presentaban pseudocrisis.

Full Text Available BACKGROUND: The ongoing epidemiological transition in Mexico minimizes the relative impact of neurocysticercosis (NC on public health. However, hard data on the disease frequency are not available. METHODOLOGY: All clinical records from patients admitted in the Instituto Nacional de Neurologia y Neurocirugia (INNN at Mexico City in 1994 and 2004 were revised. The frequencies of hospitalized NC patients in neurology, neurosurgery and psychiatry services, as well as NC mortality from 1995 through 2009, were retrieved. Statistical analyses were made to evaluate possible significant differences in frequencies of NC patients' admission between 1994 and 2004, and in yearly frequencies of NC patients' hospitalization and death between 1995 and 2009. PRINCIPAL FINDINGS: NC frequency in INNN is not significantly different in 1994 and 2004. Between these two years, clinical severity of the cases diminished and the proportion of patients living in Mexico City increased. Yearly frequencies of hospitalization in neurology and psychiatry services were stable, while frequencies of hospitalization in neurosurgery service and mortality significantly decreased between 1995 and 2009. CONCLUSIONS: Our findings show a stable tendency of hospital cases during the last decade that should encourage to redouble efforts to control this ancient disease.

The treatment of neurocysticercosis (NCC) varies with location, number and stage of the Taenia solium cysticerci (cysts). Albendazole (ABZ) effectively kills cysticerci, and subsequently induces neuro-inflammation facilitated by leukocyte infiltration. We hypothesize that immune response varies around drug responder (degenerating/dying) and non-responder (viable) cysts after ABZ and ABZ plus steroid (ABZS) therapy, which may determine the disease pathogenesis. Twenty cysticercotic swine were treated with ABZ (n = 10; group1) and ABZS (n = 10; group2). Expression of adhesion molecules, chemokines and matrix metallo-proteinases (MMPs) was measured by qRT-PCR (quantitative reverse transcriptase-polymerase chain reaction) and ELISA. Gelatin gel zymography was performed to detect the activity of MMP-2 and -9. In group1, ABZ therapy induced higher expressions of ICAM-1 (intercellular adhesion molecule-1), VCAM-1 (vascular cell adhesion molecule-1), E-selectin, MCP-1 (monocyte chemotactic protein-1), Eotaxin-1, MIP-1α (macrophage inflammatory protein-1α), RANTES (regulated on activation, normal T cell expressed and secreted), MMP-2 and MMP-9 around ABZ responder (AR) cysts. Three pigs with cyst burdens ≥10 died following ABZ therapy. However, in group2, moderate expressions of ICAM-1, VCAM-1, E-selectin, RANTES and MMP-9 were associated with ABZS responder (ASR), whereas low expressions of these molecules were associated with ABZS non-responder (ASNR) cysts. In conclusion, ABZ alone therapy is not safe since it causes death of pigs due to higher inflammatory immune response around dying cysts. However, combination therapy is an effective treatment regimen even with the high cyst burden. Copyright © 2017 Elsevier Inc. All rights reserved.

2017-11-01

There is increasing evidence of the existence of refractoriness to treatment with antiepileptic medications in those with NCC-related epilepsy. We performed a systematic review with the objective to determine the role of a cysticercotic lesion in this group of patients. We sought those manuscripts, including case reports, describing patients with NCC-related medically-intractable epilepsy who underwent epilepsy surgery and were seizure-free a year after. Only 10 manuscripts fulfilled inclusion and exclusion criteria. Three different clinical presentations were identified: 1) the cysticercotic lesion was epileptogenic, 2) there was dual pathology, including the cysticercotic lesion, with the other lesion usually being hippocampal sclerosis, and 3) the cysticercotic lesion was not related to the epileptogenic focus. In the case of an epileptogenic cysticercotic lesion, the presence of gliosis appeared to be the culprit for epileptogenicity. More studies using large cohorts of patients might be able to confirm our findings. This article is part of a Special issue entitled "Neurocysticercosis and Epilepsy". Copyright © 2017 Elsevier Inc.

In areas where cysticercosis is endemic, calcified neurocysticercosis lesion(s) (CNL) and hippocampal sclerosis (HS) commonly coexist in patients with localization-related epilepsies. To understand the pathogenesis of HS associated with CNL, we compared the characteristics of three groups of patients with antiepileptic drug-resistant epilepsies: CNL with HS, CNL without HS (CNL alone), and HS without CNL (HS alone). In comparison to patients with CNL alone, those with CNL with HS had CNL more frequently located in the ipsilateral temporal lobe. Those with CNL with HS had a lower incidence of febrile seizures, older age at initial precipitating injury and at onset of habitual complex partial seizures, and more frequent clustering of seizures and extratemporal/bitemporal interictal epileptiform discharges as compared to patients with HS alone. Our study illustrates that HS associated with CNL might have a different pathophysiologic basis as compared to classical HS. Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.

Full Text Available Introduction: Our present observational study attempted to evaluate the clinical profiles, diagnosis, treatment and follow-up results of 51 pediatric neurocysticercosis patients over a mean duration of five years (from January 2006 to December 2010. Materials and Methods: Diagnosis was mainly based on clinical features, computed tomography (CT/magnetic resonance imaging scan and exclusion of other causes. Patients with active, transitional cysts and seizure were treated with albendazole for 28 days, steroids and anticonvulsants. Results: A total of 38 patients completed this study. Mean age of the presentation was 8.47 ± 3.19 years 52.6% of the patients were female. Overall patients presented with generalized seizure in 55.3%, focal in 31.6%, headache ± vomiting in 63.2%, focal neurodeficit in 10.5% and combination of symptoms in 60.5% cases. Contrast CT brain showed a solitary lesion in 27 (71.1% and multiple in the rest. At presentation lesions were transitional in 58.2%, inactive in 20% and mixed in 14.6%. After a mean of 2 years, seizure persisted in 9 (23.7% and headache in 8 (21.1% of whom six had normal electroencephalography (EEG while one each showed focal slowing, generalized slowing and epileptiform discharges. During the follow-up, CT scan brain 44.7% lesions calcified, 31.6% disappeared, 10.5% regressed and the rest persisted. Conclusion: Solitary ring enhancing lesions (transitional stage involving the parietal lobe was the commonest CT picture at presentation. Generalized tonic-clonic seizure was the most common type of seizure. Number of lesions, persistence of lesion, number of seizures, EEG abnormality at presentation were not found to be prognostically significant (P > 0.05.

Full Text Available Neurocysticercosis, caused by encysted larvae of the tapeworm Taenia solium, is the most common infection of the central nervous system and a major public health problem in many countries. Prevalence in the region of Curitiba, located in the southern Brazilian State of Paraná, is one of the highest in the world. The genetics of host susceptibility to neurocysticercosis (NCC is still obscure. To investigate if major histocompatibility complex (MHC genes influence individual susceptibility to NCC, we performed a case-control association analysis. Fifty-two Caucasoid patients and 149 matched controls were typed for antigens of the HLA-A, B, C, DR and DQ loci. All patients had computerized tomography and clinical features compatible with parenchymal NCC. Indirect immunofluorescence of cerebrospinal fluid showed that 19 (37% of the patients presented anti-cysticercus antibodies at titers ³ 1:10. Frequencies of HLA specificities in the whole group of patients and in the subgroup with antibodies in cerebrospinal fluid were compared to those of the control group. No significant difference was found. These results do not support the hypothesis of HLA gene participation in susceptibility to parenchymal neurocysticercosis.A neurocisticercose, causada pelo cisticerco, a larva do cestóide Taenia solium, é a infecção mais comum do sistema nervoso central e constitui importante problema de saúde pública em muitos países.

Full Text Available Neurocysticercosis is a serious endemic zoonosis resulting in increased cases of seizure and epilepsy in humans. The genesis of clinical manifestations of the disease through experimental animal models is poorly exploited. The monkeys may prove useful for the purpose due to their behavior and cognitive responses mimicking man. In this study, neurocysticercosis was induced in two rhesus monkeys each with 12,000 and 6,000 eggs, whereas three monkeys were given placebo. The monkeys given higher dose developed hyperexcitability, epileptic seizures, muscular tremors, digital cramps at 10 DPI, and finally paralysis of limbs, followed by death on 67 DPI, whereas the monkeys given lower dose showed delayed and milder clinical signs. On necropsy, all the infected monkeys showed numerous cysticerci in the brain. Histopathologically, heavily infected monkeys revealed liquefactive necrosis and formation of irregular cystic cavities lined by atrophied parenchymal septa with remnants of neuropil of the cerebrum. In contrast, the monkeys infected with lower dose showed formation of typical foreign body granulomas characterized by central liquefaction surrounded by chronic inflammatory response. It was concluded that the inflammatory and immune response exerted by the host against cysticerci, in turn, led to histopathological lesions and the resultant clinical signs thereof.

Neurocysticercosis is an infection of the central nervous system by the larval stage of Taenia solium. It is a major cause of epileptic seizures in low- and middle-income countries. Corticosteroids are frequently used to reduce inflammation and perilesional edema. We aimed to evaluate their efficacy for reducing the rate of seizures and lesion persistence in imaging studies. We searched randomized controlled trials in Medline, Central, EMBASE, LILACS, and the gray literature without language restrictions. We assessed eligibility, extracted data, and assessed the risk of bias in the included studies. The main outcomes included seizure recurrence and lesion persistence on imaging studies at 6-12 months of follow-up. Risk ratios (RR) were used for evaluating the main outcomes. Thirteen studies involving 1373 participants were included. The quality of the evidence was deemed low to very low. Corticosteroids alone versus placebo/no drug (five trials) reduced the rate of seizure recurrence at 6-12 months (RR 0.46, 95% confidence interval (CI) 0.27-0.77; 426 participants) and the persistence of lesions in imaging studies (RR 0.63, 95% CI 0.43-0.92; 417 participants). No differences were noted in other comparisons, including the use of corticosteroids and albendazole combined. Corticosteroids plus albendazole increased the risk of abdominal pain, rash, and headaches (odds ratio 8.73, 95% CI 2.09-36.5; 116 participants, one trial). Although the evidence suggest corticosteroids can reduce the rate of seizure recurrence and speed up resolution of lesions at 6-12 months of follow-up, there remains uncertainty on the effect estimate due to a high risk of methodological and publication bias. More adequately performed randomized trials that evaluate the use of anthelmintics, corticosteroids, and both combined against placebo are needed.

Neurocysticercosis is a widely prevalent disease in the tropics that causes seizures and a variety of neurological symptoms in most of the world. Experimental models are limited and do not allow assessment of the degree of inflammation around brain cysts. The vital dye Evans Blue (EB) was injected into 11 pigs naturally infected with Taenia solium cysts to visually identify the extent of disruption of the blood brain barrier. A total of 369 cysts were recovered from the 11 brains and classified according to the staining of their capsules as blue or unstained. The proportion of cysts with blue capsules was significantly higher in brains from pigs that had received anthelmintic treatment 48 and 120 h before the EB infusion, indicating a greater compromise of the blood brain barrier due to treatment. The model could be useful for understanding the pathology of treatment-induced inflammation in neurocysticercosis. PMID:23684909

Full Text Available In the present study, an enzyme-linked immunosorbent assay (ELISA standardized with vesicular fluid of Taenia solium cysticerci was used to screen for IgG (total and subclasses and IgE antibodies in cerebrospinal fluid (CSF samples from patients with neurocysticercosis showing intrathecal production of specific IgG antibodies and patients with other neurological disorders. The following results were obtained: IgG-ELISA: 100% sensitivity (median of the ELISA absorbances (MEA=1.17 and 100% specificity; IgG1-ELISA: 72.7% sensitivity (MEA=0.49 and 100% specificity; IgG2-ELISA: 81.8% sensitivity (MEA=0.46 and 100% specificity; IgG3-ELISA: 63.6% sensitivity (MEA=0.12 and 100% specificity; IgG4-ELISA: 90.9% sensitivity (MEA=0.85 and 100% specificity; IgE-ELISA 93.8% sensitivity (MEA=0.60 and 100% specificity. There were no significant differences between the sensitivities and specificities in the detection of IgG-ELISA and IgE-ELISA, although in CSF samples from patients with neurocysticercosis the MEA of the IgG-ELISA was significantly higher than that of the IgE-ELISA. The sensitivity and MEA values of the IgG4-ELISA were higher than the corresponding values for the other IgG subclasses. Future studies should address the contribution of IgG4 and IgE antibodies to the physiopathology of neurocysticercosis.

Full Text Available Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5% and 30 were men (37.5%. The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated, with a 95% rate (76 cases, while the presence of hypodense lesions reached a 5% rate (4 cases. After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%. This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.Com o objetivo de iniciar um estudo sobre a neurocisticercose no Sul do Brasil, foi verificada a porcentagem de casos suspeitos de neurocisticercose em tomografia computadorizada de crânio (TCC em Santa Maria, entre janeiro de 1997 e dezembro de 1998.

Full Text Available Recent studies have suggested a possible relationship between temporal lobe epilepsy with mesial temporal sclerosis (MTS and neurocysticercosis (NC. We performed a case-control study to evaluate the association of NC and MTS. Method: We randomly selected patients with different epilepsy types, including: MTS, primary generalized epilepsy (PGE and focal symptomatic epilepsy (FSE. Patients underwent a structured interview, followed by head computed tomography (CT. A neuroradiologist evaluated the scan for presence of calcified lesions suggestive of NC. CT results were matched with patients’ data. Results: More patients in the MTS group displayed calcified lesions suggestive of NC than patients in the other groups (p=0.002. On multivariate analysis, MTS was found to be an independent predictor of one or more calcified NC lesions (p=0.033. Conclusion: After controlling for confounding factors, we found an independent association between NC calcified lesions and MTS.

Full Text Available The association between neurocysticercosis (NCC and epilepsy is well known and NCC is an important risk factor for epileptic seizures in many Taenia solium-endemic regions of the world. However, while the relationship between NCC and epilepsy is well known, the association between NCC and medically refractory (or surgically remediable epilepsy has received little attention in the past. Our experience and review of the sparse literature available suggests that NCC is causally related to surgically remediable epilepsy albeit uncommonly so and that association derives its underpinnings from several different scenarios: (1 Medically refractory lesional epilepsy, in which seizures arise from the vicinity of the calcified neurocysticercus lesion (CNL, (2 Medically refractory epilepsy with dual pathology type of relationship between the hippocampal sclerosis (HS and CNL in which both have been unequivocally demonstrated to give rise to independent seizures and (3 Mesial temporal lobe epilepsy due to HS with a distantly-located CNL, which is in itself not epileptogenic. A major point of controversy revolves around whether or not there exists a causal association between the CNL and HS. We believe that an association exists between NCC and HS and the most important factor influencing this association is the location of the CNL. Furthermore, NCC is a risk factor for medically-refractory epilepsy and that this might account for a considerable proportion of the intractable epilepsy population in endemic regions; the association has been largely ignored owing to the lack of availability of presurgical work-up facilities in these regions. Finally, from a clinical standpoint of presurgical evaluation, patients with CNL and HS should be evaluated on a case by case basis owing to disparate settings underlying the association.

Ventricular involvement in neurocysticercosis (NCC), a common serious manifestation of NCC, has distinct clinical presentations, complications, and treatments primarily because of partial or complete obstruction of the cerebrospinal fluid (CSF) flow by Taenia solium cysts. We review the clinical course, treatments, and long-term outcomes in 23 of 121 (19.0%) total NCC patients with ventricular cysts referred to the National Institutes of Health from 1985 to the October 2017. Patients had a median age of 31.8 (range: 22.4-52.6 years), were 60.9% male, diagnosed a median of 6.5 years (range: 0.17-16 years) after immigration, and were followed for a median of 3.6 years (range: 0.1-30.5 years). Other forms and manifestations of NCC were present in 73.9% (17/23). The fourth ventricle was involved in a majority (15/23, 65.2%) resulting in hydrocephalus (73.9%), ventriculitis, and periventricular edema (7/23, 30.4%). Cystectomy was accomplished in 60.9%, usually by removal of a fourth ventricular cyst through a suboccipital craniotomy. Nonresectable cysts were treated medically. Ventriculoperitoneal shunts were inserted in 43.5% (10/23) and failed in four, three from infection. Other complications included surgically induced injuries (4/23, 17.4%) and entrapment of a lateral ventricle (2/23, 8.7%). Despite a common severe early course, 90.9% (20/22) stabilized without recurrence, 15% (3/20) complained of mild-to-moderate neurological complaints, and 15% (3/20) were significantly disabled. Four patients who underwent removal of ventricular cysts without significant other NCC and who received with no cysticidal treatment became CSF cestode antigen negative without recurrence indicating that after successful extraction of cysts, additional cysticidal treatment may not be needed.

With the objective to show the characteristics of neurocysticercosis (NCC) in Brazil, was performed a critical analysis of national literature which showed a frequency of 1.5% in autopsies and 3.0% in clinical studies, corresponding to 0.3% of all admissions in general hospitals. In seroepidemiological studies the positivity of specific reactions was 2.3%. Brazilian patient with NCC presents a general clinical-epidemilogical profile (31-50 years old man, rural origin, complex partial epileptic crisis, increased protein levels or normal CSF, CT showing calcifications, constituting the inactive form of NCC), and a profile of severity (21-40 years old woman, urban origin, vascular headache and intracranial hypertension, typical CSF syndrome of NCC or alteration of two or more CSF parameters, CT showing vesicles and/or calcifications, constituting the active form of NCC). Although two localities from the state of S o Paulo have 72:100000 and 96:100000/habitants as prevalence coefficients, regional and national prevalences are very underestimated. Some aspects related to underestimation of NCC prevalence in Brazil are discussed.

Full Text Available ABSTRACT The objective of this study was to estimate the direct costs associated with the diagnosis and treatment of neurocysticercosis (NCC during pre-hospitalization, hospitalization, and post-hospitalization periods for 108 NCC patients treated at the Instituto Nacional de Neurologia y Neurocirugia (INNN in Mexico City, Mexico. Information on clinical manifestations, diagnostic tests, hospitalizations, surgical procedures, prescription medication, and other treatments was collected via medical chart reviews. Uncertain values for costs and frequency of treatments were imputed using bootstrap techniques. The average per-patient pre-hospitalization and hospitalization costs were US$ 257 (95% CI: 185 – 329 and US$ 2,576 (95% CI: 2,244 – 2,908, respectively. Post-hospitalization costs tended to decrease over time, with estimates for the first five years post-hospitalization of US$ 475 (95% CI: 423 – 527, US$ 228 (95% CI: 167 – 288, US$ 157 (95% CI: 111 – 202, US$ 150 (95% CI: 106 – 204, and US$ 91 (95% CI: 27 – 154, respectively. NCC results in a significant economic burden for patients requiring hospitalization, with this burden continuing years post-hospitalization.

Full Text Available Background: Neurocysticercosis (NCC is a common cause of epilepsy in the low- and middle-income countries. The risk factors for NCC vary from region to region. Aims: To study the risk factors NCC among patients with NCC and compare with age-and gender-matched controls without NCC. Setting and Design: Hospital-based case-control study. Materials and Methods: A total of 214 subjects were studied (109 NCC patients and 105 age- and gender-matched controls without NCC. The participants were selected from neurology and medical wards of a tertiary referral hospital in Northwest India. They were interviewed by trained medical interns using a questionnaire. Results: Patients with NCC were more likely to dispose garbage close to water source (P = 0.01, eat nonvegetarian food (P < 0.001, and often eat in restaurants (P < 0.001. Pigs were seen more in and around the NCC patient′s houses than the control subjects residential areas (P = 0.001. A total of 15% of the NCC subjects lived close to slaughter houses, while only 2.7% of the control group stayed near a slaughter house (P = 0.002. Conclusions: Unhygienic practices, nonvegetarian food, and eating in restaurants were the risk factors for NCC in this study. There is an opportunity for prevention of NCC using public education.

Full Text Available The aim of the study was to determine the most effective medical treatment of patients with chronic pancreatitis, by using either pancreatin alone or in combination with proton pump inhibitor (PPI or PPI and non-steroidal anti-inflammatory drug (NSAID. Patients with chronic pancreatitis, who did not require a surgical treatment, received medical treatment for a one–month period: 20 patients received pancreatin monotherapy; 48 patients were given a combination of pancreatin and PPI; 38 patients were treated with a combination of pancreatin, PPI and NSAID (PNP therapy group. In comparison with other groups, patients in the PNP therapy group showed improvement in body mass index, abdominal pain, bowel movements, chronic pancreatitis severity, as well as their quality of life assessment (p < 0.05. The combination of pancreatin, PPI and NSAID was the most effective among those applied in chronic pancreatitis patient treatment. A one–month long course of this therapy was safe and did not cause any significant adverse effects. The combination of pancreatin, PPI and NSAID for treatment of chronic pancreatitis can be recommended, as it is based on pathogenesis of the disease, effective, safe and economically advantageous.

The detection of antibodies to Taenia solium metacestodes is very important in the differential diagnosis of neurocysticercosis (NCC). In this study, an electroimmunotransfer blot (EITB) assay that uses an elaborate protocol with metacestode glycoproteins as antigens was compared with two other Western blots that use glycoproteins obtained using simpler methods, including an eluate from a lectin column, or the vesicular fluid (VF) of the parasite. The concordance between the three assays was 91% in patients with active NCC and 100% in patients with suspected NCC and previous documentation of negative serology. The specificities for the Western blots and the EITB assay were 98% and 100%, respectively (98% concordance). These data suggest that the simplest of these immunoassays, the one that uses the VF of T. solium metacestodes in a Western blot format, can be reliably used for the serologic diagnosis of NCC in developing countries where access to the EITB assay is difficult.

MicroRNAs (miRNAs) are short, endogenous, non-coding, single-stranded RNAs involved in post-transcriptional gene regulation. Although, several miRNAs have been identified in parasitic helminths, there is little information about their identification and function in Taenia . Furthermore, the impact of miRNAs in neurocysticercosis, the brain infection caused by larvae of Taenia solium is still unknown. During chronic infection, T. solium may activate numerous mechanisms aimed to modulate host immune responses. Helminthic miRNAs might also have effects on host mRNA expression and thus play an important role regulating host-parasite interactions. Also, the diagnosis of this disease is difficult and it usually requires neuroimaging and confirmatory serology. Since miRNAs are stable when released, they can be detected in body fluids and therefore have potential to diagnose infection, determine parasite burden, and ascertain effectiveness of treatment or disease progression, for instance. This review discusses the potential roles of miRNAs in T. solium infection, including regulation of host-parasite relationships and their eventual use as diagnostic or disease biomarkers. Additionally, we summarize the bioinformatics resources available for identification of T. solium miRNAs and prediction of their targets.

Full Text Available The difference in epilepsy burden existing among populations in tropical regions has been attributed to many factors, including the distribution of infectious diseases with neurologic sequels. To define the burden of epilepsy in Latin American Countries (LAC and to investigate the strength of association with neurocysticercosis (NCC, considered one of the leading causes of epilepsy, we performed a systematic review and meta-analysis of the literature.Studies published until 2012 were selected applying predefined inclusion criteria. Lifetime epilepsy (LTE prevalence, active epilepsy (AE prevalence, incidence, mortality, treatment gap (TG and NCC proportion among people with epilepsy (PWE were extracted. Median values were obtained for each estimate using random effects meta-analysis. The impact of NCC prevalence on epilepsy estimates was determined using meta-regression models. To assess the association between NCC and epilepsy, a further meta-analysis was performed on case-control studies.The median LTE prevalence was 15.8/1,000 (95% CI 13.5-18.3, the median AE prevalence was 10.7/1,000 (95% CI 8.4-13.2, the median incidence was 138.2/100,000 (95% CI 83.6-206.4, the overall standardized mortality ratio was 1.4 (95% CI 0.01-6.1 and the overall estimated TG was 60.6% (95% CI 45.3-74.9. The median NCC proportion among PWE was 32.3% (95% CI 26.0-39.0. Higher TG and NCC estimates were associated with higher epilepsy prevalence. The association between NCC and epilepsy was significant (p<0.001 with a common odds ratio of 2.8 (95% CI 1.9-4.0.A high burden of epilepsy and of NCC in LAC and a consistent association between these two diseases were pointed out. Furthermore, NCC prevalence and TG were identified as important factors influencing epilepsy prevalence to be considered in prevention and intervention strategies.

Full Text Available Complex aneurysms often cannot be completely excluded by a single approaches. Today successful treatment of these lesions requires a combination between microsurgical and endovascular techniques. Planning of combined treatment require a very good understanding of aneurysm anatomy and a close collaboration between neurosurgeon and neuroendovascular interventionist. Endovascular coiling can usually be used as early treatment for a partially aneurysm occlusion including the ruptured area and followed by definitive clipping. On the other hand microsurgical clipping also can be used as first treatment for complex aneurysm neck reconstruction, allowing successful secondary placement of coils inside the remnant aneurysm sac

Taeniasis refers to the infection with adult tapeworms of Taenia spp. in the upper small intestine of humans, which is also a cause of cysticercosis infection in either both humans and/or animals. Currently the most commonly applied anthelminthics for treatment of taeniasis are praziquantel and niclosamide. Praziquantel is very effective, but has the risk of induction of epileptic seizures or convulsions in carriers with asymptomatic concurrent neurocysticercosis. In contrast, niclosamide is safe and effective, but is not readily available in many endemic countries including China. In the current community-based study, we assessed the curative effect of either pumpkin seeds or areca nut extract alone in taeniasis, and also looked at synergistic effects of these two herb drugs on tapeworms. In the study group with the pumpkin seed/areca nut extract treatment, 91 (79.1%) of 115 suspected taeniasis cases (with a history of expulsion of proglottids within the previous one year) released whole tapeworms, four (3.5%) expelled incomplete strobila, and no tapeworms or proglottids were recovered in the remaining 20 cases. In these 115 persons, 45 were confirmed as taeniasis before treatment by microscopy and/or coproPCR. Forty (88.9%) of 45 confirmed cases eliminated intact worms following treatment. The mean time period for complete elimination of tapeworms in 91 taeniasis cases was 2 h (range 20 min to 8 h 30 min), and 89.0% (81) of 91 patients discharged intact worms within 3h after drug administration. In Control Group A with treatment of pumpkin seeds alone, 75.0% (9/12) of confirmed taeniasis cases expelled whole tapeworms, but the mean time period for complete elimination was about 14 h 10 min (range 3 h 20 min to 21 h 20 min), which was much longer than that (2 h) for the study group, whereas in Control Group B treated with areca nut extract alone, only 63.6% (7/11) of taeniasis cases discharged whole tapeworms, and the mean time period was 6 h 27 min (range 1-22 h

A total of 91/1,009 cases (9.02%) were considered positive to NCC; 88 (96.7%) patients had inactive form of NCC and only 3 (3.2%) patients had cysts in granulomatous process. No patients had both forms. The prevalence of NCC cases in studied group was greater in patients between 51 to 60 years old, however, difference between sex was not significant. This epidemiological pattern of NCC was similar to the first NCC study in Curitiba, performed in 1995-1996 with 9.24% of positive cases.

Full Text Available Surgical treatment of gynecomastia could present unique challenges for the plastic surgeon. Achieving a good balance between effectiveness of the selected approach and the satisfactory aesthetic outcome often is a difficult endeavor. Optimal surgical treatment involves a combination of liposuction and direct excision. In the present study the charts of 11 patients treated with suction-assisted liposuction and direct surgical excision were retrospectively reviewed; a special emphasis is placed on the surgical technique. The mean follow-up period of the patients was 11.6 months. No infection, hematoma, nipple-areola complex necrosis and nipple retraction was encountered in this series. The combined surgical treatment of gynecomastia has shown to be a reliable technique in both small and moderate breast enlargement including those with skin excess.

Neurocysticercosis (NC) is a parasitic infectious disease caused by Taenia solium eggs that set in the brain. Its incidence is increasing both in the developing and the developed world, as a result of low economical and hygiene levels and immigration, respectively. Clinical manifestation of disease varies from no symptoms to epilepsy, increased intra-cranial pressure, arachnoiditis and dementia. In order to evaluate function (perfusion) of affected brains, we studied 40 patients (21 females and 19 males, 19-71 yo) by means of SPECT (ECD, ethyl cysteinate dimer, labelled with 99mTc) and with and without contrast CT. SPECT studies were all abnormal. No difference was noted between active and inactive disease. Two SPECT patterns were noted: a) several areas of focally reduced uptake, resulting from coalescent and big lesions and large destruction of brain tissue (small, isolated and symmetric cysts seen in CT were missed by SPECT); b) diffuse atrophy with reduction of the tracer uptake, associated with ventricle dilatation, corresponding to the cases where ventricular NC was important. Interestingly, we noted diffuse hypoperfusion, with the scintigraphic pattern of atrophy in 5 cases of massive parenchymal infection; in such cases, CT signs of atrophy were clearly less prominent. The first scintigraphic aspect can be explained by the destruction of large areas of brain, which produces focal absence of perfusion; generalised vasculitis and the destruction of large portions of brain tissue could explain the difference noted between the SPECT and the CT aspects in the 5 cases of massive parenchimal infection, and this may be interesting for prognosis. Dilatation of ventricles and Sylvian fissures were interestingly prominent in SPECT. SPECT may be of great value to evaluate brain perfusion in NC (Au)

Objective: to determine the relationship between Taenia antigen (TA) detection in cerebrospinal fluid (CSF) and magnetic resonance imaging (MRI) findings in patients with definite diagnosis of neurocysticercosis (NC). Method: sixty-three patients with definite diagnosis of NC were submitted to a MRI of the brain, and to a CSF examination, with a meticulous search for TA by ELISA. Results: TA detection was positive in 36 patients (57.1%). A total of 836 lesions were analyzed, greatly within the cerebral parenchyma (98.7 of the lesions). Intact or non-degenerating cysts were the most common evolutive phase observed (50.4% of all lesions), 22.1% were degenerating cysts and 19.5% calcified cysts. We observed a significant relationship between TA levels detected and the total number of lesions and the number of non-degenerating cysts, but not with calcified lesions. Conclusion: according to our results, we propose at least four important types of contribution: TA detection may allow etiologic diagnosis in transitional phases of NC, with non-characteristic images; in final stages of evolution of cysticercoids in the CNS, lesions may not appear on CT or MRI, and TA detection may contribute to a definite etiologic diagnosis; TA detection may permit diagnosis of NC in some patients with previous negative tests for antibody detection in CSF; TA detection may represent an accurate marker of disease activity in the epileptic form of NC.

Full Text Available Recent methods, doses and results of medical treatment on taeniasis/cysticercosis, a zoo-notic parasitic disease caused by Taenia solium and Taenia saginata are discussed. In cases of cysticercosis T. solium, especially neurocysticercosis the optimal length and dose of albendazole is a course of 8 days with doses of 15 mg/kg/day divided in two times added by 50 mg/day of prednisone in the morning. The drug is effective in almost any location of the parasites for 80-90% of macroscopic cysts seen by imaging studies. For taeniasis a single dose of praziquantel, 10-15 mg/kg achieves cure rates of more than 90%. Side effects such as nausea, headache and abdominal pain are mild.  Evaluation of drug treatment is done by clinical, radiological and serological evaluation. In Papua (=Irian Jaya nine cases with suspected neurocysticercosis, serologically positive, were treated with 1200 mg single dose albendazole for 15 days. Prednisonetablets, three times daily one tablet, 5 mg during 7 days were added. After one year 6 cases were still serologic positive. At the same time praziquantel, 1200 mg, single dose was given to ten cases during 15 days and prednisone tablets, 3 times daily one tablet, 5 mg during 7 days. After one year 5 sero-positive cases were still found. Albendazole and praziquantel are both effective drugs for taeniasis and cysticercosis, with minor side effects. In addition symptomatic treatment should be given if necessary. (Med J Indones 2005; 14:253-7Keywords: albendazol, praziquantel, cysticercosis, taeniasis

Neurocysticercosis is a common helminthic infection of the central nervous system and an important cause of adult-onset epilepsy in endemic countries. However, few studies have examined associations between neurologic symptoms, serology and radiographic findings on a community-level. We conducted a population-based study of resident's ≥2 years old in a highly endemic village in Peru (pop. 454). We applied a 14 -question neurologic screening tool and evaluated serum for antibodies against Taenia solium cysticercosis using enzyme-linked immunoelectrotransfer blot (LLGP-EITB). We invited all residents ≥18 years old to have non-contrast computerized tomography (CT) of the head. Of the 385 residents who provided serum samples, 142 (36.9%) were seropositive. Of the 256 residents who underwent CT scan, 48 (18.8%) had brain calcifications consistent with NCC; 8/48 (17.0%) reported a history of headache and/or seizures. Exposure to T. solium is very common in this endemic community where 1 out of 5 residents had brain calcifications. However, the vast majority of people with calcifications were asymptomatic. This study reports a high prevalence of NCC infection in an endemic community in Peru and confirms that a large proportion of apparently asymptomatic residents have brain calcifications that could provoke seizures in the future.

Added value of antigen ELISA in the diagnosis of neurocysticercosis in resource poor settings.

Directory of Open Access Journals (Sweden)

Sarah Gabriël

Full Text Available BACKGROUND: Neurocysticercosis (NCC is the most common cause of acquired epilepsy in Taenia solium endemic areas, primarily situated in low-income countries. Diagnosis is largely based upon the "Del Brutto diagnostic criteria" using the definitive/probable/no NCC diagnosis approach. Neuroimaging and specific T. solium cysticercosis antibody detection results are at the mainstay of this diagnosis, while antigen detection in serum has never been included. This study aimed at evaluating the addition of antigen detection as a major diagnostic criterion, especially in areas where neuroimaging is absent. METHODS: The B158/B60 monoclonal antibody-based enzyme-linked immunosorbent assay (ELISA for the detection of circulating cysticercus antigen was carried out retrospectively on serum samples collected during a hospital-based study from 83 people with epilepsy (PWE in an endemic area. RESULTS: The addition of antigen results as a major criterion allowed the correct diagnosis of definitive NCC in 10 out of 17 patients as opposed to 0/17 without antigen results in the absence of neuroimaging. A sensitivity of 100% and a specificity of 84% were determined for the diagnosis of active NCC using antigen ELISA. While the use of a higher cutoff improves the specificity of the test to 96%, it decreases its sensitivity to 83%. CONCLUSIONS: In areas where neuroimaging is absent, NCC diagnosis according to the existing criteria is problematic. Taking into account its limitations for diagnosis of inactive NCC, antigen detection can be of added value for diagnosing NCC in PWE by supporting diagnostic and treatment decisions. Therefore, we recommend a revision of the "Del Brutto diagnostic criteria" for use in resource poor areas and suggest the inclusion of serum antigen detection as a major criterion.

Solitary cysticercus granuloma (SCG) is the commonest form of neurocysticercosis in the Indian subcontinent and in travelers. Several different treatment options exist for SCG. We conducted a Bayesian network meta-analysis of randomized clinical trials (RCTs) to identify the best treatment option to prevent seizure recurrence and promote lesion resolution for patients with SCG. PubMed, EMBASE and the Cochrane Library databases (up to June 1, 2015) were searched for RCTs that compared any anthelmintics or corticosteroids, alone or in combination, with placebo or head to head and reported on seizure recurrence and lesion resolution in patients with SCG. A total of 14 RCTs (1277 patients) were included in the quantitative analysis focusing on four different treatment options. A Bayesian network model computing odds ratios (OR) with 95% credible intervals (CrI) and probability of being best (Pbest) was used to compare all interventions simultaneously. Albendazole and corticosteroids combination therapy was the only regimen that significantly decreased the risk of seizure recurrence compared with conservative treatment (OR 0.32, 95% CrI 0.10-0.93, Pbest 73.3%). Albendazole and corticosteroids alone or in combination were all efficacious in hastening granuloma resolution, but the combined therapy remained the best option based on probability analysis (OR 3.05, 95% CrI 1.24-7.95, Pbest 53.9%). The superiority of the combination therapy changed little in RCTs with different follow-up durations and in sensitivity analyses. The limitations of this study include high risk of bias and short follow-up duration in most studies. Dual therapy of albendazole and corticosteroids was the most efficacious regimen that could prevent seizure recurrence and promote lesion resolution in a follow-up period of around one year. It should be recommended for the management of SCG until more high-quality evidence is available.

To prevent postoperative local recurrence of rectal cancer, we treated patients using preoperative hyperthermia (5-6 times), irradiation (total 30 Gy) and 5-fluorouracil suppository (2,000-2,500 mg). The subjects were 31 patients given combined treatments and 28 patients given surgery alone. The results were as follows: Histologically, therapeutic effects were recognized in 80.6% of patients receiving combined treatments. The mean distance from the adventitia to the site of cancer infiltration was 6.54 mm in the combined treatments group and 3.35 mm in the surgery alone group. The difference between the two was significant (p<0.05). The rate of local recurrence in the combined treatments group was less than that in the surgery alone group. No systemic side effects nor severe complications were observed during hospitalization in the combined treatments group. The survival rate of the combined treatments group was higher than that of the surgery alone group. It was considered that combined preoperative treatments for rectal cancer were beneficial to survival and local control. (author)

The present paper discusses some of the methodological issues which can confound the interpretation of clinical trials of combined modality treatment. It reviews some of the larger randomized trials which have evaluated combined modality treatment in cancers of the head and neck, lung, gastrointestinal tract and bladder. It concludes that adequate trials have yet to be performed in many of thses sites, but that at present, evidence for long-term benefit from adjunctivechemotherapy is meagre. Finally, it suggests some possible mechanisms which might heve limited the benefit of chemotherapy when added to radiation treatment. (Author). 87 refs.; 4 figs.; 4 tabs

Estimating the non-monetary burden of neurocysticercosis in Mexico.

Directory of Open Access Journals (Sweden)

Rachana Bhattarai

Full Text Available BACKGROUND: Neurocysticercosis (NCC is a major public health problem in many developing countries where health education, sanitation, and meat inspection infrastructure are insufficient. The condition occurs when humans ingest eggs of the pork tapeworm Taenia solium, which then develop into larvae in the central nervous system. Although NCC is endemic in many areas of the world and is associated with considerable socio-economic losses, the burden of NCC remains largely unknown. This study provides the first estimate of disability adjusted life years (DALYs associated with NCC in Mexico. METHODS: DALYs lost for symptomatic cases of NCC in Mexico were estimated by incorporating morbidity and mortality due to NCC-associated epilepsy, and morbidity due to NCC-associated severe chronic headaches. Latin hypercube sampling methods were employed to sample the distributions of uncertain parameters and to estimate 95% credible regions (95% CRs. FINDINGS: In Mexico, 144,433 and 98,520 individuals are estimated to suffer from NCC-associated epilepsy and NCC-associated severe chronic headaches, respectively. A total of 25,341 (95% CR: 12,569-46,640 DALYs were estimated to be lost due to these clinical manifestations, with 0.25 (95% CR: 0.12-0.46 DALY lost per 1,000 person-years of which 90% was due to NCC-associated epilepsy. CONCLUSION: This is the first estimate of DALYs associated with NCC in Mexico. However, this value is likely to be underestimated since only the clinical manifestations of epilepsy and severe chronic headaches were included. In addition, due to limited country specific data, some parameters used in the analysis were based on systematic reviews of the literature or primary research from other geographic locations. Even with these limitations, our estimates suggest that healthy years of life are being lost due to NCC in Mexico.

We used baseline data on 154 symptomatic neurocysticercosis (NCC) patients in Ecuador to identify predictors of the burden of cysts. We ran logistic regression models with the burden of cysts as the outcome, defined as the number of cysts in the brain (1 vs >1), and having cysts in all 3 phases of evolution (active, transitional and calcifications) vs restaurants or street vendors, working in a manual labour job. We found that the odds of having multiple NCC cysts was higher among those working in manual labour (OR=3.5, p=0.004), and those who ate most meals outside the home had higher odds of having cysts in all 3 phases (OR=5.0, p=0.007). Burden of cysts may be a useful outcome when looking to identify exposure risk factors in the absence of an uninfected control group. Copyright © 2012 Royal Society of Tropical Medicine and Hygiene.

Neurocysticercosis (NCC), which is caused by accidental ingestion of eggs of the pork tapeworm, Taenia solium, was common in Bali, Indonesia until the early 1990s. However, improved education on hygiene and sanitation, a move to keeping pigs indoors, and improvement of economic and living conditions have substantially reduced the occurrence of NCC in Bali. Since 2011, T. solium tapeworm carriers (T. solium taeniasis) and heavily infected pigs and dogs have exclusively been detected from villages in mountainous regions of northeastern Bali where NCC and ocular cysticercosis (OCC) cases have also been identified. In response to this continued area of high infection, a one-day workshop was convened to discuss how to prevent and control this potentially lethal zoonotic parasitic infection in Bali. This review presents an overview of the current status of T. solium taeniasis and cysticercosis in Indonesia and proposes a strategy for the prevention and control of this zoonosis in Bali.

Carriers of the pork tapeworm, Taenia solium, are the sole source of cysticercosis, a parasitic tissue infection. When tapeworm eggs excreted by the carrier are ingested, tapeworm larvae can form cysts. When cysts form in the brain, the condition is called neurocysticercosis and can be especially severe. In Los Angeles County an average of 136 county residents are hospitalized with neurocysticercosis each year. The prevalence of Taenia solium carriage is largely unknown because carriage is asymptomatic, making detection difficult. The identification and treatment of tapeworm carriers is an important public health measure that can prevent additional neurocysticercosis cases.

Whey proteins, enriched protein fractions from milk, are of great interest as ingredients due to nutritional value associated with its functional properties. These proteins could have their structural properties improved when some treatments are applied, such as thermal and gamma irradiation or when some compounds are added. The current work aimed to study the viscometer behavior of whey dispersions submitted to two different combined treatments: (1) thermal plus irradiation and (2) thermal plus vacuum and N 2 plus irradiation. Dispersions of whey protein in water (5% and 8% protein (w/v) base) and containing proteins and glycerol at ratios 1:1 and 2:1 (protein:glycerol) were submitted to both combined treatments. The irradiation doses were 0, 5, 15 and 25 kGy. The viscosity of the two combined treatments and for four levels of absorbed doses is presented and the combined effects are discussed. The thermal treatment combined with gamma irradiation contributed to increase the viscosity as irradiation doses increases for both (5% and 8%) concentrations of proteins (p<0.05). For protein and glycerol solutions, the irradiation dose seemed to result in a slightly increase. The vacuum applied before the irradiation showed a small contribution

Full Text Available The effects of ultrasonic treatment (UT, 400 watts for 6 min combined with peracetic acid (PA, 0.4% (W/W treatment on fruit decay, browning, and quality and physiological changes in loquat fruit stored at 20°C were investigated. The results showed that treatment with UT or PA alone significantly reduced both decay and browning index in loquat fruit compared with the control. The combined treatment was more effective in decreasing decay and browning index and maintaining higher quality parameters than UT or PA treatment alone. Loquat fruits treated with the combined treatment maintained higher activities of polyphenol oxidase (PPO and peroxidase (POD than those treated with other treatments. In addition, UT combined with PA treatment significantly reduced the increase of firmness and increased fruit extractable juice, total soluble solid (TSS, and ascorbic acid content in loquat fruit. Moreover, the contents of total phenolics and total flavonoids were enhanced by the combination of UT and PA treatment. The combination of UT and PA treatment could be a useful method to reduce decay and browning in loquat fruit stored at room temperature, which has potential for application in the loquat industry.

A dramatic increasing immigration flow was recorded in Europe during the last years. Only in Sicily 120,239 people arrived in 2014. Immigrants may carry neglected tropical diseases endemic in their origin countries. The aim of our study was to evaluate the frequency of geo-helminthiasis, and in particular of intestinal taeniasis, in a sample of migrants hosted in a large asylum seeker centre in the province of Catania. A stool sample was obtained from all the enrolled subjects and a coproparasitological examination was performed. Out of the 274 enrolled subjects (249 men; mean age 26.4 ± 6.2), 30 (11%) carried at least one helminthic infestation. Ancylostomatidae, Trichuris trichiura and Taenia species (spp) were the most common, the latter found in 6 (2.16%) subjects. T. solium carriers can represent a focus of infection for the more complex neurocysticercosis. Even if coproparasitological examination did not allow us to differentiate Taenia spp, we cannot exclude the presence of T. solium carriers among these subjects. Further studies, including coproantigen ELISA to detect Taenia spp, should be carried out in larger samples to better estimate the real burden of T. solium carriers.

Full Text Available Obesity is a chronic disease associated with excess morbidity and mortality. Clinical treatment, however, currently offers disappointing results, with very high rates of weight loss failure or weight regain cycles, and only two drugs (orlistat and sibutramine approved for long-term use. Drugs combinations can be an option for its treatment but, although widely used in clinical practice, very few data are available in literature for its validation. Our review focuses on the rationale for their use, with advantages and disadvantages; on combinations often used, with or without studies; and on new perspectives of combinations being studied mainly by the pharmaceutical industry.

Alkaline pretreatment combined with high pressure homogenization (HPH) was applied to promote sewage sludge disintegration. For sewage sludge with a total solid content of 1.82%, sludge disintegration degree (DD(COD)) with combined treatment was higher than the sum of DD(COD) with single alkaline and single HPH treatment. NaOH dosage ⩽0.04mol/L, homogenization pressure ⩽60MPa and a single homogenization cycle were the suitable conditions for combined sludge treatment. The combined sludge treatment showed a maximum DD(COD) of 59.26%. By regression analysis, the combined sludge disintegration model was established as 11-DD(COD)=0.713C(0.334)P(0.234)N(0.119), showing that the effect of operating parameters on sludge disintegration followed the order: NaOH dosage>homogenization pressure>number of homogenization cycle. The energy efficiency with combined sludge treatment significantly increased compared with that with single HPH treatment, and the high energy efficiency was achieved at low homogenization pressure with a single homogenization cycle.

This study compares the differential efficacy of three groups of treatments for agoraphobia: paroxetine combined with cognitive-behavioral therapy, paroxetine combined with cognitive-behavioral therapy and virtual reality exposure, and a group with only paroxetine. 99 patients with agoraphobia were finally selected. Both combined treatment groups received 11 sessions of cognitive-behavioral therapy, and one of the groups was also exposed to 4 sessions of virtual reality treatment. Treatments were applied in individual sessions once a week for 3 months. The three treatment groups showed statistically significant improvements. In some measures, combined treatment groups showed greater improvements. The virtual reality exposure group showed greater improvement confronting phobic stimuli. Treatments combining psychopharmacological and psychological therapy showed greater efficacy. Although the use of new technologies led to greater improvement, treatment adherence problems still remain.

Full Text Available La neurocisticercosis (NCC es la parasitosis humana más frecuente del sistema nervioso central y es causada por las larvas del céstodo Taenia solium. La NCC es endémica en prácticamente todos los paises en vías de desarrollo. En general se presenta como formas intraparenquimales asociadas con convulsiones o formas extraparenquimales asociadas con hipertensión endocraneana. La sospecha clínica y epidemiológica es importante pero el diagnóstico se realiza primariamente por imágenes y se confirma con serología. La tomografía axial computarizada y la resonancia magnética son las pruebas imagenológicas usadas. Como prueba confirmatoria se usa el diagnóstico inmunológico a través de western blot, que actualmente se pude realizar en el Instituto Nacional de Ciencias Neurológicas tanto en suero como en líquido cefalorraquídeo. El tratamiento involucra medidas sintomáticas (control de convulsiones o hipertensión endocraneana según sea el caso y tratamiento antiparasitario (albendazol o praziquantel. El tratamiento antiparasitario debe hacerse bajo condiciones de hospitalización y en hospitales de tercer nivel.Neurocysticercosis (NCC is the most common parasitic disease of the central nervous system and is caused by larvae of the tapeworn Taenia solium.

Qatar is a small country on the Eastern coast of the Arabian Peninsula. Its population is a unique mixture of native citizens and immigrants. We aimed to describe the features of epilepsy in Qatar as such information is virtually lacking from the current literature. We summarized information retrospectively collected from 468 patients with epilepsy seen through the national health system adult neurology clinic. Epilepsy was classified as focal in 65.5% of the cases and generalized in 23%. Common causes of epilepsy were as follows: stroke (9%), hippocampal sclerosis (7%), infections (6%), and trauma (6%). Sixty-six percent of patients were receiving a single antiepileptic drug, with levetiracetam being the most frequently prescribed drug (41% of subjects). When the patients were divided by geographical background, remote infections caused the epilepsy in 15% of Asian patients (with neurocysticercosis accounting for 10%) but only in 1% of Qatari and 3% of Middle East/North African subjects (with no reported neurocysticercosis) (pepilepsy in Qatar. The geographical origin of patients adds to the heterogeneity of this disorder. Neurocysticercosis should be in the etiological differential diagnosis of epilepsy in patients coming from Southeast Asian countries, despite the fact that it is not endemic to Qatar. The choice of antiepileptic drugs is influenced by the availability of individual agents in the patients' native countries but had no bearing on the final seizure outcome.

Neurocysticercosis (NCC), an infection of the brain by Taenia solium (Ts) cysts, is the most common cause of adult-onset epilepsy in developing countries. Serological testing consists primarily of varying methods to detect antibodies in body fluids and more recently antigen (Ag) detection assays to identify individuals or animals with viable parasites. Antigen assays currently in use employ monoclonal antibodies (mAbs) raised against T. saginata, which have known cross reactivity to animal cestodes but are highly specific in human samples. We produced, characterized and tested 21 mAbs raised against T. solium whole cyst antigens, vesicular fluid or excretory secretory products. Reactivity of the TsmAbs against specific cyst structures was determined using immunofluorescence and immunohistochemistry on histological sections of Ts muscle cysts. Four TsmAbs reacted to vesicular space alone, 9 to the neck and cyst wall, one to the neck and vesicular space and 7 to the neck, cyst wall and vesicular space. An in-house ELISA assay to detect circulating Ts antigen, using the TsmAbs as capture antibodies and a rabbit polyclonal anti-Ts whole cyst antibody as a detector antibody demonstrated that eight of the 21 TsmAbs detected antigens in known NCC-positive human sera and three of these also in urine samples. Reactivity was expressed as normalized ratios of optical densities (OD positive control/OD negative control). Three TsmAbs had ratios >10 and five between 2 and 10. The TsmAbs have potential utility for the diagnosis and post-treatment monitoring of patients with viable NCC infections. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Glued laminated timber is an engineered product that requires precision manufacturing in all its stages. The finished product can only be tested in laboratory conditions. However, it is necessary to have quality control in the production to ensure that the properties of the glulam are appropriate to the product specified requirements in accordance with the standards. In Brazil is still no specific standard of qualification for the manufactures of Glulam. In this context, different kinds of wood, adhesives and preservative treatments in the composition of Glulam can be used. This paper aims to evaluate the proposed trials conducted with combinations of four Brazilian reforestation species, three adhesives and three types of preservative treatment. As a result was observed that combinations, which showed the best performance, were pine and parica wood, with any type of adhesive or treatment investigated, which can be used in exterior applications. Lyptus® wood for any combination of treatments falls into the internal use class. Teak wood can be used indoors (adhesive polyurethane and all kinds of treatment or external (phenol resorcinol formaldehyde adhesive and all kinds of treatment.

Full Text Available According to the World Health Organization, a third of the world’s population is infected with tuberculosis. The disease is responsible for nearly 2 million deaths each year and over 8 million were developing active diseases. Moreover, according to WHO (2000, tuberculosis deaths are estimated to increase to 35 million between 2000-2020. The majority of tuberculosis patients worldwide are still treated with single drugs, or with 2-drug fixed-dose combinations (FDCs. To improve tuberculosis treatment, 2- and 3-drug FDCs were recommended by the World Health Organization (WHO as part of the DOTS strategy. Since 1999 a 4-drug FDC was included on the WHO Model List of Essential Drugs. Today, FDCs are important tools to further improve the quality of care for people with TB, and accelerate DOTS expansion to reach the global TB control targets. Fixed dose combination TB drugs could simplifies both treatment and management of drug supply, and may prevent the emergence of drug resistance .Prevention of drug resistance is just one of the potential benefits of the use of FDCs. FDCs simplify administration of drugs by reducing the number of pills a patient takes each day and decreasing the risk of incorrect prescriptions. Most tuberculosis patients need only take 3–4 FDCs tablets per day during the intensive phase of treatment, instead of the 15–16 tablets per day that is common with single-drug formulations It is much simpler to explain to patients that they need to take four tablets of the same type and colour, rather than a mixture of tablets of different shapes, colours and sizes. Also, the chance of taking an incomplete combination of drugs is eliminated, since the four essential drugs are combined into one tablet. FDCs are also simpler for care-givers as they minimize the risk of confusion. Finally, drug procurement, in all its components (stock management, shipping, distribution, is simplified by FDCs. Adverse reactions to drugs are not more

Acute fascioliasis (FA), cystic echinococcosis (CE) and neurocysticercosis (NCC) are three endemic parasitic diseases in Chile for whom there is scarce information about the economic impact they represent during management at the hospital. To quantify and compare hospital care expenses caused by these three endemic helminth infections in a Chilean hospital. Retrospective analysis of hospital costs at a referral hospital in Santiago between 2006 and 2010. Hospital databases were used to identify patients with the corresponding infections, and those with sufficient data on hospital costs were included. A total of 16 patients representing 21 cases were identified and analyzed: four with AF, eleven with CE, and six with NCC. Median hospital expenses for cases with AF were US$ 1799 and mainly caused by bed-day costs. Median hospital costs for cases of CE were US$ 4707 and the most important costs components were medications, bed-day costs and consumables. NCC patients had median costs of US$ 1293, which were mainly due to bed-day costs. Non-parenchymatous or mixed forms of NCC showed a trend toward higher hospital costs compared with parenchymatous forms. Although helminth infections in Chile, an upper middle income country, are declining and considered rare in routine clinical practice, hospital care expenses caused by patients with AF, CE, and NCC are high and might still present an important economic burden to the Chilean healthcare system.

Full Text Available "Neurocysticercosis" - involvement of the central nervous system (CNS by taenia solium, is one of the most common parasitic diseases of the CNS. However, spinal involvement by neurocysticercosis is uncommon. Spinal intramedullary cysticercosis involving the conus medullaris is an uncommon clinical condition, which may mimic an intramedullary tumor and can lead to irreversible neurological deficits if untreated. Here, we report a 31-year-old male patient with cysticercosis in the conus medullaris of the spinal cord. Magnetic resonance imaging revealed a well-defined round intramedullary lesion at D12-L1 vertebral levels, which was homogeneously hypointense on T1WI and hyperintense on T2WI with peripheral edema. Since the patient had progressive neurological deficits, surgery was performed to decompress the spinal cord. Histopathology examination of the removed lesion proved it to be cysticercosis. In this report, we also discuss the principles of diagnosis and treatment of intramedullary cysticercosis in combination with literature review.

The age of patients varied from 6 to 59 years of whom 28 (56% were vegan. We were also able to detect 4 types of lesions viz. calcified lesions (14, small hypodense i.e. vesicle (12, bright central spot i.e. vesicular lesion with central spot (2 and ring enhancement (22. For 3 patients, further imaging investigation (MRI was needed to confirm the diagnosis. We calculated the specificity and sensitivity of CT scan of brain diagnosing NC which was found to be 64% and 100%, respectively. Conclusions: Although, the sample may not be the representatives of the whole community, the findings suggest that cysticercosis is a significant but under-recognized public health concern in Kolkata.

Irradiation combined with other processes can contribute to insuring food safety to consumers and controlling severe losses during transportation and commercialisation. We have demonstrated that using in synergy with other treatments; a lower dose could be used to eliminate pathogenic bacteria and permit a better protection of the sensorial quality and to prolong the shelf life of foods. Results indicated that some bacteria are more sensitive to irradiation under modified atmosphere (MAP) and the presence of active compound can increase the bacterial radiosensitivity by more than 4 times under air and by more than 10 times under MAP. Mild heat treatment or addition of natural antimicrobial compounds before irradiation treatment has also permitted an increase of Bacillus cereus radiosensitization. An increase of the bacterial radiosensitization of 1.5 and 1.56 was respectively observed. The effectiveness of the use of edible coating containing natural antimicrobial compounds, modified atmosphere packaging (MAP) or mild treatment before irradiation treatment was demonstrated in order to inactivate Listeria monocytogenes, Salmonella typhimurium, Escherichia coli and Bacillus cereus growth or B. cereus spore germination, to increase the bacterial sensitivity to irradiation, to reduce the water loss and to extend the shelf life of the food when stored at 4 deg C. Also, the use of edible coating previously crosslinked by irradiation have permitted a better control of the active compounds release. Studies of combined treatments were used in ready to eat vegetables, fruits and meat products. (author)

Li, Jing; Wang, Yan; Zhu, Yu; Oupický, David

2013-12-10

Cancer treatment that uses a combination of approaches with the ability to affect multiple disease pathways has been proven highly effective in the treatment of many cancers. Combination therapy can include multiple chemotherapeutics or combinations of chemotherapeutics with other treatment modalities like surgery or radiation. However, despite the widespread clinical use of combination therapies, relatively little attention has been given to the potential of modern nanocarrier delivery methods, like liposomes, micelles, and nanoparticles, to enhance the efficacy of combination treatments. This lack of knowledge is particularly notable in the limited success of vectors for the delivery of combinations of nucleic acids with traditional small molecule drugs. The delivery of drug-nucleic acid combinations is particularly challenging due to differences in the physicochemical properties of the two types of agents. This review discusses recent advances in the development of delivery methods using combinations of small molecule drugs and nucleic acid therapeutics to treat cancer. This review primarily focuses on the rationale used for selecting appropriate drug-nucleic acid combinations as well as progress in the development of nanocarriers suitable for simultaneous delivery of drug-nucleic acid combinations.

Rapid increase in cystic volume of an anaplastic astrocytoma misdiagnosed as neurocysticercosis: A case report

Science.gov (United States)

Li, Hong-Jiang; Han, Hong-Xiu; Feng, Dong-Fu

2016-01-01

Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

Full Text Available Alberto F Rubio-Guerra1, David Castro-Serna2, Cesar I Elizalde Barrera2, Luz M Ramos-Brizuela21Metabolic and Research Clinic, 2Internal Medicine Department, Hospital General de Ticomán SS DF, MéxicoAbstract: Recent guidelines for the management of hypertension recommend target blood pressures <140/90 mmHg in hypertensive patients, or <130/80 mmHg in subjects with diabetes, chronic kidney disease, or coronary artery disease. Despite the availability and efficacy of antihypertensive drugs, most hypertensive patients do not reach the recommended treatment targets with monotherapy, making combination therapy necessary to achieve the therapeutic goal. Combination therapy with 2 or more agents is the most effective method for achieving strict blood pressure goals. Fixed-dose combination simplifies treatment, reduces costs, and improves adherence. There are many drug choices for combination therapy, but few data are available about the efficacy and safety of some specific combinations. Combination therapy of calcium antagonists and inhibitors of the renin-angiotensin-aldosterone system (RAAS are efficacious and safe, and have been considered rational by both the JNC 7 and the 2007 European Society of Hypertension – European Society of Cardiology guidelines for the management of arterial hypertension. The aim of this review is to discuss some relevant issues about the use of combinations with calcium channel blockers and RAAS inhibitors in the treatment of hypertension.Keywords: hypertension, calcium channel blockers, renin-angiotensin-aldosterone system inhibitors, fixed-dose combination, adherence

Clinicopathological studies on preoperative three combined treatments with hyperthermo-chemo-radiotherapy for rectal cancer

Energy Technology Data Exchange (ETDEWEB)

Yoshioka, Yuji [Kyoto Prefectural Univ. of Medicine (Japan)

1995-08-01

To prevent local recurrence of rectal cancer postoperatively, we treated patients using preoperative hyperthermia (5-6 times), irradiation (total 30 Gy) and a 5-Fluorouracil suppository (2000-2500 mg). The subjects were 31 patients given combined preoperative treatments and 28 patients given surgery alone. The results were as follows: Histologically, therapeutic effects were recognized in 80.6% of the combined treatments group. The mean distance from the adventitia to the site of cancer infiltration was 6.44 mm in the combined treatments group and 3.35 mm in the surgery alone group. The difference between the two was significant (p<0.05). The combined treatments produced a reduced tumor infiltration into the anal side, and resulted in making a safe margin for anastomosis. The rate of local recurrence in the combined treatments group was less than that of the surgery alone group. No systematic side effects or severe complications were observed during hospitalization in the combined treatments group. The survival rate of the combined treatments group was higher than that of the surgery alone group. It was considered that combined preoperative treatments for rectal cancer is beneficial to expand indications of super low anterior resection. (author).

Neurocysticercosis (NCC) is a parasitic infection of central nervous system (CNS). Expression of adhesion molecules, chemokines and matrix metalloproteinases (MMPs) were investigated on brain tissues surrounding viable (n=15) and degenerating cysticerci (n=15) of Taenia solium in swine by real-time RT-PCR and ELISA. Gelatin gel zymography was performed for MMPs activity. ICAM-1 (intercellular adhesion molecule-1), E-selectin, MIP-1α (macrophage inflammatory protein-1α), Eotaxin-1 and RANTES (regulated on activation, normal T cell expressed and secreted) were associated with degenerating cysticerci (cysts). However, VCAM-1 (vascular cell adhesion molecule-1), MCP-1 (monocyte chemotactic protein-1), MMP-2 and MMP-9 were associated with both viable and degenerating cysts. In conclusion, viable and degenerating cysticerci have different immune molecule profiles and role of these molecules in disease pathogenesis needs to be investigated. Copyright © 2015 Elsevier B.V.

Methods A retrospective investigation of patients with TLE-HS was conducted in a tertiary center. Results Seventy-nine (62.2%, 37 (29.1%, 6 (4.7%, and 5 (3.9% patients were Engel class I, II, III, and IV, respectively. Fifty-two (71.2% patients with epilepsy durations ≤ 10 years prior to surgery were seizure-free 1 year after the operation compared to 27 (50.0% patients with epilepsy durations > 10 years (p = 0.0121. Forty-three (72.9% patients with three or fewer lobes affected by NCC were seizure-free one year after the operation, and 36 (52.9% patients with more than three involved lobes were seizure-free after surgery (p = 0.0163. Conclusions Longer epilepsy durations and multiple lobe involvement predicted worse seizure outcomes in TLE-HS plus NCC patients.

We describe a special treatment for the malignant peritoneal pseudomyxoma as suggested by Sugarbaker. Shortly, it is a combination of surgical cytoreduction with a curative aim, completed with inmediate postoperative intraperitoneal chemotherapy. Having in mind the lack of metastasic danger of these tumours, as well as its lack of infiltrative character, by this surgical technique which consists in five different ''peritonectomies'', one may be able to free the patient of macroscopic tumour. The additional intraperitoneal chemotherapy might contribute to increase the survival of these patients and, perhaps, even to cure them. (Author) 12 refs

The risk of sepsis development increases when thermal burns and other trauma occur in combination with exposure to radiation. Only surgical correction of the life-threatening state recommends within 48 hours after irradiation. All other arrangements have to carry out when hemopoiesis recovery will complete. However exposed patients with combined injuries (CI) die during the first two or three weeks mainly due to sepsis. Therefore prophylaxis and preventive therapy of infectious complications are need early. Actual difficulties in choice of valid treatment procedure for acute radiation syndrome (ARS) exhibit additional aggravation under CI. The available facts prove decreasing early therapy efficiency for rather high dose exposure and wound trauma occurrence. The own results showed that bacterial polysaccharide pyrogenal, glycopin (synthetic analogue of muramil-dipeptide), thymus preparations (thymozin, thymotropin, thymogen), tuftsin, heterologic human and bovine immunoglobulins did not modify the low values of 30-day survival under CI (irradiation + thermal burn). Single injection of prodigiozan, zymozan and some other yeast polysaccharides in 1 hr after CI resulted at moderate increasing of survival. The main purpose of this study, which bases upon our understanding of CI pathogenesis, was search more effective means for preventive treatment of combined radiation injuries. Two groups of remedies were under study. The first group included so called 'biological response modifiers' (BRM). These agents may increase host defences to infection, macrophage's activity and hemopoietic growth factor's secretion. The second group included antibiotics that should be directed against the potential gram-negative as well as gram-positive pathogens and simultaneously be useful for selective decontamination of gastrointestinal tract.

Combined modality chemoirradiation is commonly used as a component of treatment in combination with maximum resection for both high-risk resectable and locally advanced primary or recurrent rectal cancers. With surgically resected but high-risk rectal cancers, postoperative chemoirradiation has been shown to improve both disease control (local and distant) and survival (disease-free and overall) and was recommended as standard adjuvant treatment at the 1990 National Institute of Health (NIH) Consensus Conference on Adjuvant treatment for patients with rectal and colon cancers. Subsequent intergroup trials are being conducted to help define optimal combinations of postoperative chemoirradiation for resected high-risk rectal cancers and to test sequencing issues of preoperative versus postoperative chemoirradiation. With locally unresectable primary or recurrent colorectal cancers, standard therapy with surgery, external beam irradiation (EBRT) and chemotherapy is often unsuccessful. When intraoperative electron irradiation (IOERT) is combined with standard treatment, local control and survival appear to be improved in separate analyses from the Mayo Clinic and the Massachusetts General Hospital (MGH). However, routine use of systemic therapy is also needed as a component of treatment, in view of high rates of systemic failure. (orig.)

Uncontrolled acromegaly results in approximately 2-fold excess mortality. Pituitary surgery is first-line therapy, and medical treatment is indicated for persistent disease. While cabergoline and pegvisomant are used in select patients, somatostatin receptor ligands (SRLs) remain the cornerstone of medical treatment. Management of patients poorly responsive to SRLs is therefore, challenging. The purpose of this review is to highlight the options for combination medical therapy in the treatment of acromegaly, with an emphasis on efficacy and safety. All original articles/abstracts detailing combination medical therapy in acromegaly were identified from a PubMed search. Studies reviewed included retrospective and open-label prospective studies. While the combination of SRL and cabergoline was generally well tolerated, a lower baseline insulin-like growth factor-1 (IGF-1) level was the best predictor of efficacy; this combination may be most effective in patients with mildly elevated IGF-1. SRL-pegvisomant combination normalized IGF-1 in the majority of patients; continued efficacy despite individual drug dosing reduction was also reported. The risk of significant liver enzyme elevation was, however, higher than that reported with SRL monotherapy; close monitoring is recommended. Data on pegvisomant-cabergoline combination is limited, but this may be an option in the setting of SRL intolerance. Reports on temozolomide used in combination with other medical therapies in patients with aggressive GH-secreting tumors are also summarized. While more prospective, randomized controlled trials on long-term efficacy and safety are needed, combination medical therapy remains a treatment strategy that should be considered for acromegaly patients poorly responsive to SRLs.

For the treatment of vitiligo, narrowband UVB (NBUVB) light is considered the most effective for nonsegmental vitiligo, while excimer laser treatment is commonly used for localized vitiligo. However, treatment areas may potentially be missed with excimer laser treatment. We aimed to evaluate the effect of combinational treatment with NBUVB light and excimer laser on vitiligo. All patients were first treated with NBUVB; excimer laser was then applied in conjunction with NBUVB phototherapy due to a slow response or no further improvement with continuous NBUVB treatment alone. To minimize adverse effects, a fixed dose of NBUVB was administered, and the dose of excimer laser was increased based on patient response. Among 80 patients, 54 patients showed responses after combination with excimer laser; however, 26 patients (32.5%) showed no remarkable change after combination therapy. Of the 26 patients who showed no further response, 12 patients (46.1%) presented with vitiligo on the acral areas, which are known to the least responsive sites. Our study suggests that combined treatment of NBUVB and excimer laser in vitiligo may enhance the treatment response without remarkable side effects, therefore might also increase the compliance of the patients to the treatment. © 2015 John Wiley & Sons A/S.

generated by a mathematical model of the competitive growth of multiple strains of Escherichia coli.Results: Simulation studies showed that sequential use of tetracycline and ampicillin reduced the level of double resistance, when compared to the combination treatment. The effect of the cycling frequency...... frequency did not play a role in suppressing the growth of resistant strains, but the specific order of the two antimicrobials did. Predictions made from the study could be used to redesign multidrug treatment strategies not only for intramuscular treatment in pigs, but also for other dosing routes.......Background: Combination treatment is increasingly used to fight infections caused by bacteria resistant to two or more antimicrobials. While multiple studies have evaluated treatment strategies to minimize the emergence of resistant strains for single antimicrobial treatment, fewer studies have...

Full Text Available Abstract Background Central nervous system (CNS barriers play a pivotal role in the protection and homeostasis of the CNS by enabling the exchange of metabolites while restricting the entry of xenobiotics, blood cells and blood-borne macromolecules. While the blood–brain barrier and blood-cerebrospinal fluid barrier (CSF control the interface between the blood and CNS, the ependyma acts as a barrier between the CSF and parenchyma, and regulates hydrocephalic pressure and metabolic toxicity. Neurocysticercosis (NCC is an infection of the CNS caused by the metacestode (larva of Taenia solium and a major cause of acquired epilepsy worldwide. The common clinical manifestations of NCC are seizures, hydrocephalus and symptoms due to increased intracranial pressure. The majority of the associated pathogenesis is attributed to the immune response against the parasite. The properties of the CNS barriers, including the ependyma, are affected during infection, resulting in disrupted homeostasis and infiltration of leukocytes, which correlates with the pathology and disease symptoms of NCC patients. Results In order to characterize the role of the ependymal barrier in the immunopathogenesis of NCC, we isolated ependymal cells using laser capture microdissection from mice infected or mock-infected with the closely related parasite Mesocestoides corti, and analyzed the genes that were differentially expressed using microarray analysis. The expression of 382 genes was altered. Immune response-related genes were verified by real-time RT-PCR. Ingenuity Pathway Analysis (IPA software was used to analyze the biological significance of the differentially expressed genes, and revealed that genes known to participate in innate immune responses, antigen presentation and leukocyte infiltration were affected along with the genes involved in carbohydrate, lipid and small molecule biochemistry. Further, MHC class II molecules and chemokines, including CCL12, were found

In locally advanced oral cancer, the main modalities of treatment, e.g. surgery and radiotherapy, most often fail to control the disease when used singly. A combination policy of surgery and radiotherapy achieves adequate control of the disease. In order to improve the results in advanced oral cancer, chemotherapy given prior to and during radiation treatment and judicious combination of surgery offer the best possible approach in the management. The experience in the combination policy in the treatment of oral cancer in Northern India is dealt with. (auth.)

Oral combination therapy: repaglinide plus metformin for treatment of type 2 diabetes.

Raskin, P

2008-12-01

Type 2 diabetes is characterized by decreases in insulin secretion and insulin sensitivity. Several classes of oral antidiabetic medications are currently approved for the treatment of type 2 diabetes. A stepwise treatment approach from monotherapy to combination therapy is traditionally used; however, the frequency of treatment failure with monotherapy has resulted in a move towards earlier treatment with combination therapies that target the two principal defects in glycaemic control. One such combination regimen is repaglinide (a prandial glucose regulator that increases insulin release) plus metformin (an insulin sensitizer that inhibits hepatic glucose output, increases peripheral glucose uptake and utilization and minimizes weight gain). Findings from several clinical trials have shown that combination therapy with repaglinide plus metformin is well tolerated and results in greater reductions of haemoglobin A(1c) and fasting plasma glucose values compared with either monotherapy. Repaglinide may also provide a more suitable alternative to combination therapy with sulphonylureas and metformin because of its reduced propensity for hypoglycaemia. The combination regimen of repaglinide plus metformin should therefore be considered as a valuable option in the management of patients with type 2 diabetes when monotherapy is no longer adequate.

Full Text Available We investigated the relationship between CT findings - number and the viability phase of the parasites - and the seizure frequency in children with neurocysticercosis before and short-term after antiepileptic drug (AED introduction. We only found a significant interaction between stage of parasitic infection and number of lesions on seizure frequency after AED treatment. Patients with more than five lesions on active or transitional stages had higher seizure frequency predicting a worse short-term prognosis.No presente estudo, investigou-se a relação entre os achados tomográficos - número e estágio de viabilidade dos parasitas - e a frequência de crises epilépticas em crianças com neurocisticercose antes e logo após a introdução do tratamento com drogas antiepilépticas. Encontramos que a interação entre o estágio do parasita e o número de lesões influenciam significativamente a frequência de crises somente após o tratamento. Pacientes com mais do que cinco lesões em fase ativa ou transicional tiveram maior frequência de crises predizendo um pior prognóstico.

The effect of irradiation with heat combination treatment on the shelf life and quality of mango puree was studied. Thermal inactivation of polyphenol oxidase enzyme at 80 degree C and 15 min. was used as a measure of adequacy of pre-heat treatment. Irradiation of mango puree after heat treatment at dosage of 0, 2, 4, 6 and 8 kGy showed no change in mc, pH, acidity, and TSS but during storage, growth of microorganisms brought changes in these values. Irradiation in combination with low temperature (5 degree C) reduced discoloration and darkening rate during storage. Irradiation dose from 0 to 8 kGy resulted in log linear reductions in microorganism levels but at 6 and 8 kGy, there was no growth of microorganisms. Products irradiated at 8 kGy showed no microorganism growth at both temperatures

Highlights: · The work focused on hazardous wastewater (antibiotic wastewater) treatment. · Complete degradation of the antibiotics achieved by the treatment process. · The SBR performance was found to be very sensitive to BOD 5 /COD ratio below 0.40. · Combined photo-Fenton-SBR process is a feasible treatment process for the antibiotic wastewater. - Abstract: The study examined combined photo-Fenton-SBR treatment of an antibiotic wastewater containing amoxicillin and cloxacillin. Optimum H 2 O 2 /COD and H 2 O 2 /Fe 2+ molar ratio of the photo-Fenton pretreatment were observed to be 2.5 and 20, respectively. Complete degradation of the antibiotics occurred in one min. The sequencing batch reactor (SBR) was operated at different hydraulic retention times (HRTs) with the wastewater treated under different photo-Fenton operating conditions (H 2 O 2 /COD and H 2 O 2 /Fe 2+ molar ratio). The SBR performance was found to be very sensitive to BOD 5 /COD ratio of the photo-Fenton treated wastewater. Statistical analysis of the results indicated that it was possible to reduce the Fe 2+ dose and increase the irradiation time of the photo-Fenton pretreatment. The best operating conditions of the combined photo-Fenton-SBR treatment were observed to be H 2 O 2 /COD molar ratio 2, H 2 O 2 /Fe 2+ molar ratio 150, irradiation time 90 min and HRT of 12 h. Under the best operating conditions, 89% removal of sCOD with complete nitrification was achieved and the SBR effluent met the discharge standards.

2016-06-01

Enterococci are common causes of infective endocarditis (IE) in both health care and community-based setting. Enterococcal IE requires bactericidal therapy for an optimal outcome. For decades, cell-wall-active antimicrobial agents (penicillins or vancomycin) in combination with aminoglycosides were the cornerstone of the treatment; however, the emergence of antibiotic resistance has significantly reduced the efficacy of these regimens. Data for this review were identified by searches of MEDLINE and references from relevant articles on antibiotic combination regimens for the treatment of enterococcal IE. Abstracts presented in scientific conferences were not searched for. New effective and safe combination treatments, including double-β-lactam and daptomycin/β-lactam combination, are proving useful for the management of IE due to enterococci.

An exploratory study was made to determine if combining u.v. and gamma radiation treatment at selective doses would decrease the fungal decay incidence in papaya (Carica papaya L. var. Solo), and thereby increase the marketable life of the fruit. Also studied was the effect of the combined treatment on the spores of Aschochyta spp., Colletotrichium spp. and Phytophthora spp., which are commonly found on papaya grown in Hawaii. This was to test the postulate that the combined treatment would prevent photoreactivation of the disrupted nuclei in microorganisms and lead to eventual death. Experimental results did not indicate a conclusive trend to effectiveness but suggested a number of problems to be resolved before the treatment can become useful in fungal decay control of fruits.

1981-01-01

Research with subtropical fruits such as papayas and mangoes had advanced beyond the experimental stage in South Africa. This may be attributed to the potential economic benefits likely to be obtained from the combination of heat and irradiation treatments. The outcome of recent marketing trials, however, revealed several problem areas which need further investigation. Some of these problems were studied in greater detail and are reported in this presentation. The effect of time delays between hot-water and irradiation treatments on the efficacy in disease control in the fruit, has received particular attention in the investigations. Efforts have also been made to correlate these results with those obtained in fungal studies in the laboratory. These and other factors relating to the technological feasibility in the use of combined treatments for the preservation of mangoes and papayas are discussed and recommendations or guidelines for future studies are given in this paper.

In certain diseases clinical experts may judge that the intervention with the best prospects is the addition of two treatments to the standard of care. This can either be tested with a simple randomized trial of combination versus standard treatment or with a 2 x 2 factorial design. We compared the two approaches using the design of a new trial in tuberculous meningitis as an example. In that trial the combination of 2 drugs added to standard treatment is assumed to reduce the hazard of death by 30% and the sample size of the combination trial to achieve 80% power is 750 patients. We calculated the power of corresponding factorial designs with one- to sixteen-fold the sample size of the combination trial depending on the contribution of each individual drug to the combination treatment effect and the strength of an interaction between the two. In the absence of an interaction, an eight-fold increase in sample size for the factorial design as compared to the combination trial is required to get 80% power to jointly detect effects of both drugs if the contribution of the less potent treatment to the total effect is at least 35%. An eight-fold sample size increase also provides a power of 76% to detect a qualitative interaction at the one-sided 10% significance level if the individual effects of both drugs are equal. Factorial designs with a lower sample size have a high chance to be underpowered, to show significance of only one drug even if both are equally effective, and to miss important interactions. Pragmatic combination trials of multiple interventions versus standard therapy are valuable in diseases with a limited patient pool if all interventions test the same treatment concept, it is considered likely that either both or none of the individual interventions are effective, and only moderate drug interactions are suspected. An adequately powered 2 x 2 factorial design to detect effects of individual drugs would require at least 8-fold the sample size of the

Hair chemical treatments, such as dyeing and straightening products, are known to cause damage that can be assessed by protein loss. The aim of this study was to evaluate the hair protein loss caused by combined chemical treatments (dye and relaxer) using the validated bicinchoninic acid (BCA) method. Three kinds of straighteners, based on ammonium thioglycolate, guanidine hydroxide and sodium hydroxide, were evaluated and the least harmful combination indicated. Caucasian virgin dark brown hair tresses were treated with developed natural brown color oxidative hair dyeing and/or straightening commercial products based on ammonium thioglycolate, sodium hydroxide, or guanidine hydroxide. Protein loss quantification was assessed by the validated BCA method which has several advantages for quantifying protein loss in chemically treated hair. When both treatments (straightening and dyeing) were combined, a higher negative effect was observed, particularly for dyed hair treated with sodium hydroxide. In this case, a 356% increase in protein loss relative to virgin hair was observed and 208% in relation to only dyed hair. The combination of dying and relaxers based on ammonium thioglycolate or guanidine hydroxide caused a small increase in protein loss, suggesting that these straightening products could be the best alternatives for individuals wishing to combine both treatments. These results indicated that when application of both types of products is desired, ammonium thioglycolate or guanidine hydroxide should be chosen for the straightening process. © 2015 Wiley Periodicals, Inc.

Bacterial biofilms are a growing concern in a broad range of areas. In this study, a mixture of RNA bacteriophages isolated from municipal wastewater was used to control and remove biofilms. At the concentrations of 400 and 4 × 10(7) PFU/mL, the phages inhibited Pseudomonas aeruginosa biofilm formation by 45 ± 15% and 73 ± 8%, respectively. At the concentrations of 6,000 and 6 × 10(7) PFU/mL, the phages removed 45 ± 9% and 75 ± 5% of pre-existing P. aeruginosa biofilms, respectively. Chlorine reduced biofilm growth by 86 ± 3% at the concentration of 210 mg/L, but it did not remove pre-existing biofilms. However, a combination of phages (3 × 10(7) PFU/mL) and chlorine at this concentration reduced biofilm growth by 94 ± 2% and removed 88 ± 6% of existing biofilms. In a continuous flow system with continued biofilm growth, a combination of phages (a one-time treatment at the concentration of 1.9 × 10(8) PFU/mL for 1 h first) with chlorine removed 97 ± 1% of biofilms after Day 5 while phage and chlorine treatment alone removed 89 ± 1% and 40 ± 5%, respectively. For existing biofilms, a combined use of a lower phage concentration (3.8 × 10(5) PFU/mL) and chlorination with a shorter time duration (12 h) followed by continuous water flushing removed 96 ± 1% of biofilms in less than 2 days. Laser scanning confocal microscopy supplemented with electron microscopy indicated that the combination treatment resulted in biofilms with lowest cell density and viability. These results suggest that the combination treatment of phages and chlorine is a promising method to control and remove bacterial biofilms from various surfaces.

Oller, I.; Malato, S.; Sanchez-Perez, J.A.

2011-01-01

Nowadays there is a continuously increasing worldwide concern for development of alternative water reuse technologies, mainly focused on agriculture and industry. In this context, Advanced Oxidation Processes (AOPs) are considered a highly competitive water treatment technology for the removal of those organic pollutants not treatable by conventional techniques due to their high chemical stability and/or low biodegradability. Although chemical oxidation for complete mineralization is usually expensive, its combination with a biological treatment is widely reported to reduce operating costs. This paper reviews recent research combining AOPs (as a pre-treatment or post-treatment stage) and bioremediation technologies for the decontamination of a wide range of synthetic and real industrial wastewater. Special emphasis is also placed on recent studies and large-scale combination schemes developed in Mediterranean countries for non-biodegradable wastewater treatment and reuse. The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation. Furthermore, better economic models must be developed to estimate how the cost of this combined process varies with specific industrial wastewater characteristics, the overall decontamination efficiency and the relative cost of the AOP versus biological treatment.

Full Text Available BACKGROUND: Malignant mesothelioma (MM is a rare, highly aggressive tumor, associated to asbestos exposure. To date no chemotherapy regimen for MM has proven to be definitively curative, and new therapies for MM treatment need to be developed. We have previously shown in vivo that piroxicam/cisplatin combined treatment in MM, specifically acts on cell cycle regulation triggering apoptosis, with survival increase. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed, at molecular level, the apoptotic increase caused by piroxicam/cisplatin treatment in MM cell lines. By means of genome wide analyses, we analyzed transcriptional gene deregulation both after the single piroxicam or cisplatin and the combined treatment. Here we show that apoptotic increase following combined treatment is mediated by p21, since apoptotic increase in piroxicam/cisplatin combined treatment is abolished upon p21 silencing. CONCLUSIONS/SIGNIFICANCE: Piroxicam/cisplatin combined treatment determines an apoptosis increase in MM cells, which is dependent on the p21 expression. The results provided suggest that piroxicam/cisplatin combination might be tested in clinical settings in tumor specimens that express p21.

Combined chemotherapy and radiotherapy in the treatment of lung cancer

Wolf, M.

1992-01-01

In the past decade the prognosis of patients with locally advanced lung cancer has not been altered significantly. In both small and non-small cell lung cancer cure rates are poor and 5-year survival rate still has not exceeded the 5% borderline. Despite of initially high response rates, a vast majority of patients suffered from tumor progression within 2 years after the start of treatment. Sites of tumor progression are either the primary tumor or the occurrence of distant metastases. Therefore, improvements of both local and systemic tumor control are necessary to increase long-term survival rate in lung cancer. Combined chemo- and radiotherapy may be an appropriate treatment approach to reach these aims. In patients with locally advanced lung cancer combined chemo-radiotherapy aims at overcoming radio- and chemo-therapy resistance as a cause of local treatment failure and at early eradication of distant micrometastases as a cause of systemic treatment failure.

Fibromyalgia is a chronic widespread pain condition affecting millions of people worldwide. Current pharmacotherapies are often ineffective and poorly tolerated. Combining different agents could provide superior pain relief and possibly also fewer side effects. To assess the efficacy, safety, and tolerability of combination pharmacotherapy compared to monotherapy or placebo, or both, for the treatment of fibromyalgia pain in adults. We searched CENTRAL, MEDLINE, and Embase to September 2017. We also searched reference lists of other reviews and trials registries. Double-blind, randomised controlled trials comparing combinations of two or more drugs to placebo or other comparators, or both, for the treatment of fibromyalgia pain. From all studies, we extracted data on: participant-reported pain relief of 30% or 50% or greater; patient global impression of clinical change (PGIC) much or very much improved or very much improved; any other pain-related outcome of improvement; withdrawals (lack of efficacy, adverse events), participants experiencing any adverse event, serious adverse events, and specific adverse events (e.g. somnolence and dizziness). The primary comparison was between combination and one or all single-agent comparators. We also assessed the evidence using GRADE and created a 'Summary of findings' table. We identified 16 studies with 1474 participants. Three studies combined a non-steroidal anti-inflammatory drug (NSAID) with a benzodiazepine (306 participants); two combined amitriptyline with fluoxetine (89 participants); two combined amitriptyline with a different agent (92 participants); two combined melatonin with an antidepressant (164 participants); one combined carisoprodol, paracetamol (acetaminophen), and caffeine (58 participants); one combined tramadol and paracetamol (acetaminophen) (315 participants); one combined malic acid and magnesium (24 participants); one combined a monoamine oxidase inhibitor with 5-hydroxytryptophan (200

The delicate balance required to maintain homeostasis of the central nervous system (CNS) is controlled by the blood-brain barrier (BBB). Upon injury, the BBB is disrupted compromising the CNS. BBB disruption has been represented as a uniform event. However, our group has shown in a murine model of neurocysticercosis (NCC) that BBB disruption varies depending upon the anatomical site/vascular bed analyzed. In this study further understanding of the mechanisms of BBB disruption was explored in blood vessels located in leptomeninges (pial vessels) and brain parenchyma (parenchymal vessels) by examining the expression of junctional complex proteins in murine brain infected with Mesocestoides corti. Both pial and parenchymal vessels from mock infected animals showed significant colocalization of junctional proteins and displayed an organized architecture. Upon infection, the patterned organization was disrupted and in some cases, particular tight junction and adherens junction proteins were undetectable or appeared to be undergoing proteolysis. The extent and timing of these changes differed between both types of vessels (pial vessel disruption within days versus weeks for parenchymal vessels). To approach potential mechanisms, the expression and activity of matrix metalloproteinase-9 (MMP-9) were evaluated by in situ zymography. The results indicated an increase in MMP-9 activity at sites of BBB disruption exhibiting leukocyte infiltration. Moreover, the timing of MMP activity in pial and parenchymal vessels correlated with the timing of permeability disruption. Thus, breakdown of the BBB is a mutable process despite the similar structure of the junctional complex between pial and parenchymal vessels and involvement of MMP activity.

The anticancer agent genistein inhibits cell growth of tumor cell lines from various malignancies. In our study, we investigated the effectiveness of combined treatment of ionizing radiation (IR) with genistein on cervical HeLa cells and its possible mechanism. It was found that the inhibitory rate in cells with combined treatment was significantly higher than that of the cells treated with IR or genistein alone. After treatments of IR (4 Gy) combined with genistein (40 μmol/L), the apoptotic index of the cells was significantly increased and the cells were arrested in the G2/M phase. Survivin mRNA expression increased after IR (4 Gy), while it significantly decreased after combined treatment. These findings indicated that genistein enhanced the radiosensitivity of cervical cancer HeLa cells, and the mechanisms for this action might include increase of apoptosis, decrease of survivin expression, and prolongation of cell cycle arrest.

Full Text Available Abstract Background In certain diseases clinical experts may judge that the intervention with the best prospects is the addition of two treatments to the standard of care. This can either be tested with a simple randomized trial of combination versus standard treatment or with a 2 × 2 factorial design. Methods We compared the two approaches using the design of a new trial in tuberculous meningitis as an example. In that trial the combination of 2 drugs added to standard treatment is assumed to reduce the hazard of death by 30% and the sample size of the combination trial to achieve 80% power is 750 patients. We calculated the power of corresponding factorial designs with one- to sixteen-fold the sample size of the combination trial depending on the contribution of each individual drug to the combination treatment effect and the strength of an interaction between the two. Results In the absence of an interaction, an eight-fold increase in sample size for the factorial design as compared to the combination trial is required to get 80% power to jointly detect effects of both drugs if the contribution of the less potent treatment to the total effect is at least 35%. An eight-fold sample size increase also provides a power of 76% to detect a qualitative interaction at the one-sided 10% significance level if the individual effects of both drugs are equal. Factorial designs with a lower sample size have a high chance to be underpowered, to show significance of only one drug even if both are equally effective, and to miss important interactions. Conclusions Pragmatic combination trials of multiple interventions versus standard therapy are valuable in diseases with a limited patient pool if all interventions test the same treatment concept, it is considered likely that either both or none of the individual interventions are effective, and only moderate drug interactions are suspected.

Full Text Available Studies have shown that topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT can be used successfully for the treatment of oral verrucous hyperplasia (OVH. Studies have also demonstrated that cryotherapy could be used as a treatment modality for OVH lesions. In this case report, we tested the efficacy of topical ALA-PDT, combined with cryogun cryotherapy, for an extensive OVH lesion on the right buccal mucosa of a 65-year-old male areca quid chewer. The tumor was cleared after six treatments of combined topical ALA-PDT and cryogun cryotherapy. No recurrence of the lesion was found after a follow-up period of 18 months. We suggest that our combined treatment protocol may be effective in treating OVH lesions. The treatment course may be slightly shortened with this combined protocol and was well tolerated by the patient.

Taeniasis/cysticercosis caused by Taenia solium is a frequent parasitic infection of the human brain in most of the world. Rapid and simple screening tools to identify taeniasis and cysticercosis cases are needed for control programs, mostly to identify tapeworm carriers which are the source of infection and need to be treated, or as tools for point-of-care case detection or confirmation. These screening assays should be affordable, reliable, rapid, and easy to perform. Immunochromatographic tests meet these criteria. To demonstrate proof of principle, we developed and evaluated two magnetic immunochromatographic tests (MICTs) for detection of human Taenia solium taeniasis antibodies (ES33-MICT) and neurocysticercosis antibodies (T24-MICT). These assays detected stage-specific antibodies by using two recombinant proteins, rES33 for detection of taeniasis antibodies and rT24H for detection of cysticercosis antibodies. The sensitivity and specificity of the ES33-MICT to detect taeniasis infections were 94.5% and 96%, respectively, and those of the T24-MICT to detect cases of human cysticercosis with two or more viable brain cysts were 93.9% and 98.9%, respectively. These data provide proof of principle that the ES33- and T24-MICTs provide rapid and suitable methods to identify individuals with taeniasis and cysticercosis.

The many-year experience with the treatment of the cervix uteri cancer has indicated that a combined method in case of the appropriate indications provides for high and persistant delayed results. The five-year recovery of patients at all stages was noted in 78.7% (1 stage-87.3%; 2 stage-71.6 %, 3 stage-41.7%). Improvement of therapeutic and diagnostic methods, strict adherence to the principles of a differential approach to selecting the type of therapy enabled increasing the per cent of a five-year cure from 68.9%' (1945-46) to 91.8% in 1965-69. The clinical features of microinvasive cervix uteri canner (stage 1a) made it possible to reduce the extent of the treatment applied on account of excluding a radiation component and lessening the extent of surgical intervention. A five-year cure by the surgical method in patients with cancer of stage 1a made up 97%. The results of the combined therapy in patients cervix uteri with stage 1b within the same period yielded 94%

Effects of heat treatment, gamma irradiation, and combined treatments on the shelf-life of fresh avocados (Persea americana L.). Experiments to determine the effective irradiation conditions to prolong the shelf-life of fresh avocados were conducted at the centre for the Application of Isotopes washed and dried, then divided into 4 groups, namely for control (A), dipped in hot water at 40 0 C for 20 minutes (heat treatment, B), irradiated at a dose of 25 Gy (C), and combination of hot water dipping (40 0 C for 20 minutes) and irradiation at a 25 Gy (D). The samples were stored at room temperature. Evaluation on physical and chemical properties of the samples was done daily up to 10 days' storage. Parameters observed were texture, moisture and fat contents, percentage of weight loss, percentage of mature fruit, and subjective organoleptic evaluation. It was found that treated samples with and without combination treatment were still in good condition until 10 days of storage. It could be concluded that dipping in hot water, either alone or in combination with irradiation at a dose of 25 Gy could extend the shelf-life of fresh avocado up to 10 days at room temperature compared to only 5 days of the control.

The causal relationship between neurocysticercosis infection and the development of epilepsy - a systematic review.

Science.gov (United States)

Gripper, Lucy B; Welburn, Susan C

2017-04-05

Neurocysticercosis (NCC) is a parasitic infection of the human central nervous system, the most common form of which involves infection of the brain parenchyma with the larval form of the Taenia solium tapeworm. A causal relationship between such an NCC infection and the development of epilepsy in infected individuals is acknowledged, in part supported by high levels of comorbidity in endemic countries worldwide. This study undertook a systematic review and critical analysis of the NCC-epilepsy relationship with the primary objective of quantifying the risk of developing epilepsy following NCC infection. A secondary aim was to analyse the proportions of NCC-associated epilepsy within different populations. Significant emphasis was placed on the importance of neuroimaging (CT or MRI) availability and use of clear guidelines for epilepsy diagnosis, in order to avoid overestimations of prevalence rates of either condition; a limitation identified in several previous studies. A common odds ratio of 2.76 was identified from meta-analysis of case-control studies, indicating that an individual infected with NCC has almost a three times higher risk of developing epilepsy than an uninfected individual. Furthermore, meta-analysis of studies identified a common proportion of 31.54% of epilepsy cases associated with NCC infection which suggests that amongst epileptic populations in at risk countries, approximately one-third may be associated with NCC infection. A significant finding was the lack of good clinical data to enable accurate determination of a causal relationship. Even studies that were included had noticeable limitations, including a general lack of consistency in diagnostics, and lack of accurate epidemiological data. This review highlights a need for consistency in research in this field. In the absence of reliable estimates of its global burden, NCC will remain of low priority in the eyes of funding agencies - a truly neglected disease.

However, some patients may not respond well to biologic agents or phototherapy on their own and may require combination therapy. Skillfully combining a biologic agent and phototherapy may provide an additive improvement without much increase in risks.Objective: To summarize the current state of evidence for the efficacy and safety of combining biologics with phototherapy in the treatment of moderate-to-severe plaque psoriasis.Methods: We conducted an extensive search on Pubmed database for English language literature that evaluated the use of a combination of biologic and phototherapy for the treatment of moderate-to-severe psoriasis through January 2016. The search included the following keywords: psoriasis, etanercept, adalimumab, infliximab, ustekinumab, biologics, phototherapy, and combination therapy.Results: The primary literature included randomized controlled trials, a head-to-head study, open-label controlled and uncontrolled trials, case series, and case reports. Etanercept was used in over half of the reported cases, but other biologic agents used included ustekinumab, adalimumab, and infliximab. The vast majority of phototherapy was narrowband ultraviolet B (NBUVB radiation. Most cases reported enhanced improvement with combination therapy.

Full Text Available Neurocysticercosis (NC is a clinically and radiologically heterogeneous parasitic disease caused by the establishment of larval Taenia solium in the human central nervous system. Host and/or parasite variations may be related to this observed heterogeneity. Genetic differences between pig and human-derived T. solium cysticerci have been reported previously. In this study, 28 cysticerci were surgically removed from 12 human NC patients, the mitochondrial gene that encodes cytochrome b was amplified from the cysticerci and genetic variations that may be related to NC heterogeneity were characterised. Nine different haplotypes (Ht, which were clustered in four haplogroups (Hg, were identified. Hg 3 and 4 exhibited a tendency to associate with age and gender, respectively. However, no significant associations were found between NC heterogeneity and the different T. solium cysticerci Ht or Hg. Parasite variants obtained from patients with similar NC clinical or radiological features were genetically closer than those found in groups of patients with a different NC profile when using the Mantel test. Overall, this study establishes the presence of genetic differences in the Cytb gene of T. solium isolated from human cysticerci and suggests that parasite variation could contribute to NC heterogeneity.

The results of the present experiment on combined treatment with 18 kR X-rays followed by treatment with 0.25, 0.50 and 1.00 per cent aqueous solution of colchicine on white fruit colour variety of T. anguina have been found to be very interesting. The treatments have led to an increase in surviving plants till maturity, reduction in percentage of pollen mother cells with chromosomal aberrations and increase in pollen fertility. Analysis of root tip mitosis has shown that treatment with X-rays produces dicentric bridge and fragment while only polyploid cells were observed after treatment with colchicine. Combined treatment with X-rays and colchicine, produces both chromosomal aberrations and polyploid cells. Simultaneously, it reduces the percentage of cells with chromosomal aberrations and those with polyploid chromosome numbers. Desirable variability in seed number, seed weight and size, seed oil and punicic acid content were observed in both combined and individual treatment. (author). 6 refs., 3 tabs

A 9-year-old girl with Papillon-Lefèvre syndrome (PLS) was treated orthodontically 24 months after the start of mechanical and antibiotic therapy in adjunct with periodontal treatment every 6 weeks. After achieving stable periodontal conditions, orthodontic treatment was commenced to correct the teeth position, facial profile, and maxillary protraction. Following the combination therapy and a failure to detect Actinobacillus actinomycetemcomitans from any site in the oral cavity, orthodontic treatment with a fixed appliance was performed aside from creating space for eruption of permanent teeth. We found that combined periodontal and orthodontic treatment of PLS may be successful with a complex interdisciplinary regimen and close follow up. This is a 2-year follow-up case report of a girl with PLS. Orthodontic and periodontic therapy were offered using combined treatments of orthodontic and periodontal with the benefit of prosthodontic consultation, resulting in a treatment plan.

Full Text Available To study the clinical efficiency of using mesodiencephalic modulation (MDM as therapy in the combination treatment of patients with pulmonary tuberculosis, the authors examined two groups: 1 the patients who received a MDM cycle in combination with chemotherapy regimens (a study group; 2 those treated using standard chemotherapy regimens (a control group. By the end of one-month therapy, the study group ceased bacterial excretion twice more often than the control group that exhibited the similar results only by the end of three-month treatment. MDM as therapy produced positive X-ray changes in 76.0% of the cases in the study group and in 44.4% in the control one. MDM used in the combination treatment of patients with tuberculosis makes it possible to reduce the length of hospital stay, the number of round-the-clock beds, and the cost of treating these patients.

The outcome of treatment with antidepressants varies markedly across people with the same diagnosis. A clinically significant prediction of outcomes could spare the frustration of trial and error approach and improve the outcomes of major depressive disorder through individualized treatment selection. It is likely that a combination of multiple predictors is needed to achieve such prediction. We used elastic net regularized regression to optimize prediction of symptom improvement and remission during treatment with escitalopram or nortriptyline and to identify contributing predictors from a range of demographic and clinical variables in 793 adults with major depressive disorder. A combination of demographic and clinical variables, with strong contributions from symptoms of depressed mood, reduced interest, decreased activity, indecisiveness, pessimism and anxiety significantly predicted treatment outcomes, explaining 5-10% of variance in symptom improvement with escitalopram. Similar combinations of variables predicted remission with area under the curve 0.72, explaining approximately 15% of variance (pseudo R(2)) in who achieves remission, with strong contributions from body mass index, appetite, interest-activity symptom dimension and anxious-somatizing depression subtype. Escitalopram-specific outcome prediction was more accurate than generic outcome prediction, and reached effect sizes that were near or above a previously established benchmark for clinical significance. Outcome prediction on the nortriptyline arm did not significantly differ from chance. These results suggest that easily obtained demographic and clinical variables can predict therapeutic response to escitalopram with clinically meaningful accuracy, suggesting a potential for individualized prescription of this antidepressant drug.

Objective: To discuss the technique, efficacy and clinical significance of cryoablation combined with transcatheter arterial chemoembolization(TACE) for the treatment of advanced hepatic carcinoma. Methods: One hundred and ninety-two patients, who accorded with the selected criterion, were divided into TACE group (n=100) and combination group (cryotherapy combined with TACE, n=92). Pre-and post-treatment AFP level, recurrence rate and life span between two groups were compared. Results: The complete necrosis rate of the tumor and the recurrence rate in TACE group were 29% and 42%, which were 88.04% and 24% in combination group, respectively. The serum AFP level was significantly decreased after treatment in both groups (P<0.05), and the reduction in AFP level was significantly greater in combination group than that in TACE group (P<0.05). During a follow-up of 30 months the survival rate at each evaluation period of combination group was higher than that of TACE group without exception. Conclusion: As an effective and safe technique, cryoablation combined with chemoembolization is far superior to simple TACE in treating advanced hepatic carcinoma. (authors)

Epilepsy is one of the most common neurological disorders prevalent in childhood period. There is scarcity of epidemiological data, required to plan services in resource constrained developing nations. To study the prevalence and treatment gap in childhood epilepsy in north Indian city, in the age group of 1-18 years. A two stage stratified cluster sampling; probability proportionate to size (PPS) was employed. A ten question screening questionnaire was employed to identify the presence of epilepsy. Definitions provided by International League against Epilepsy (ILAE) were used to classify screen positive subjects as epilepsy and to calculate the treatment gap. The prevalence rate for epilepsy was 6.24/1000 population. Febrile seizures and neurocysticercosis were most common causes of symptomatic seizures in childhood. This study of epidemiology of epilepsy provides valuable aid in optimizing effective community approach, thereby improving outcomes of childhood epilepsy.

Selective mutism (SM) is a debilitating childhood anxiety disorder characterized by a persistent lack of speech in certain social settings and is considered hard to treat. Cognitive behavioral therapy (CBT) and pharmacological treatments are the best described treatments in the literature. To test whether there is evidence on treatment based on CBT, medication or a combination of these. Systematic and critical review of the literature on CBT and/or pharmacological treatments of SM. Literature was sought on PubMed, Embase and Psycinfo in March 2017. Of the included studies, six examined CBT, seven pharmacologic treatment and two a combination of these. Using CBT 53/60 children improved symptomatically whilst respectively 55/67 and 6/7 improved using pharmacologic- and combination-treatment. Pharmacologic treatment and especially CBT showed promising results supported by some degree of evidence, which combination treatment lacks. Yet small numbers, few RCTs, heterogeneous study designs, lack of consistent measures, short treatment and follow-up periods, generally limits the evidence. This needs focus in future research.

Full Text Available Abstract Uveal melanoma (UM is the most prevalent intraocular malignant tumor in the Western world. The prognosis of survival in the presence of metastatic disease is 2-7 months, depending on the treatment applied. This article presents a case of metastatic UM with successful complex treatment of liver metastases. A 49-year old female, underwent removal of the right eyeball in 1996 due to a histologically confirmed uveal melanoma. After 11 years, CT revealed a mass in the left kidney and multiple metastases in the liver. After left nephrectomy, 6 chemotherapy courses with dacarbazine were performed. The increasing liver metastases were observed. Additional 4 intraarterial (i/a chemotherapy courses were administered using cisplatin, doxorubicin, fluorouracil, and interferon alfa. After few courses increase in CTC Grade 4 liver transaminases was seen. A partial response was observed, and in December 2008 the patient underwent surgery removing all liver metastases by 7 wedge or atypical resections. All margins were tumor-free. 21 months after liver resections and 14 years since diagnosis, the patient is alive without evidence of disease. Successful treatment of metastatic uveal melanoma was due to a timely application of a combination of several treatment methods and good prognostic factors of the patient.

An understanding of growth dynamics of tumors is important in understanding progression of cancer and designing appropriate treatment strategies. We perform a comparative study of the hyperbolastic growth models with the Weibull and Gompertz models, which are prevalently used in the field of tumor growth. The hyperbolastic growth models H1, H2, and H3 are applied to growth of solid Ehrlich carcinoma under several different treatments. These are compared with results from Gompertz and Weibull models for the combined treatment. The growth dynamics of the solid Ehrlich carcinoma with the combined treatment are studied using models H1, H2, and H3, and the models are highly accurate in representing the growth. The growth dynamics are also compared with the untreated tumor, the tumor treated with only iodoacetate, and the tumor treated with only dimethylsulfoxide, and the combined treatment. The hyperbolastic models prove to be effective in representing and analyzing the growth dynamics of the solid Ehrlich carcinoma. These models are more precise than Gompertz and Weibull and show less error for this data set. The precision of H3 allows for its use in a comparative analysis of tumor growth rates between the various treatments

The COMBINE (combined pharmacotherapies and behavioral intervention) clinical trial recently evaluated the efficacy of pharmacotherapies, behavioral therapies, and their combinations for the treatment of alcohol dependence. Previously, the cost and cost-effectiveness of COMBINE have been studied. Policy makers, patients, and nonalcohol-dependent individuals may be concerned not only with alcohol treatment costs but also with the effect of alcohol interventions on broader social costs and outcomes. To estimate the sum of treatment costs plus the costs of health care utilization, arrests, and motor vehicle accidents for the 9 treatments in COMBINE 3 years postrandomization. A cost study based on a randomized controlled clinical trial. : The study involved 786 participants 3 years postrandomization. Multivariate results show no significant differences in mean costs between any of the treatment arms as compared with medical management (MM) + placebo for the 3-year postrandomization sample. The median costs of MM + acamprosate, MM + naltrexone, MM + acamprosate + naltrexone, and MM + acamprosate + combined behavioral intervention were significantly lower than the median cost for MM + placebo. The results show that social cost savings are generated relative to MM + placebo by 3 years postrandomization, and the magnitude of these cost savings is greater than the costs of the COMBINE treatment received 3 years prior. Our study suggests that several alcohol treatments may indeed lead to reduced median social costs associated with health care, arrests, and motor vehicle accidents.

Full Text Available The aim of the present study was to analyse Taenia solium metacestode antigens that were derived from the unbound fraction of jacalin affinity chromatography and subsequent tert-octylphenoxy poly (oxyethylene ethanol Triton X-114 (TX-114 partitioning in the diagnosis of human neurocysticercosis (NCC. Immunoassays were designed to detect T. solium-specific IgG antibodies by ELISA and immunoblot. Serum samples were collected from 132 individuals who were categorised as follows: 40 had NCC, 62 presented Taenia spp or other parasitic diseases and 30 were healthy individuals. The jacalin-unbound (J unbound fraction presented higher sensitivity and specificity rates than the jacalin-bound fraction and only this fraction was subjected to subsequent TX-114 partitioning, resulting in detergent (DJ unbound and aqueous (AJ unbound fractions. The ELISA sensitivity and specificity were 85% and 84.8% for J unbound , 92.5% and 93.5% for DJ unbound and 82.5% and 82.6% for AJ unbound . By immunoblot, the DJ unbound fraction showed 100% sensitivity and specificity and only serum samples from patients with NCC recognised the 50-70 kDa T. solium-specific components. We conclude that the DJ unbound fraction can serve as a useful tool for the differential immunodiagnosis of NCC by immunoblot.

Biological targeted treatment to date has minor effect when given as monotherapy, but some of the drugs hold promise as an adjunct...... to chemotherapy. It should, however, be noted that most of the trials are based on few patients, and thus far the literature does not allow for a conclusion as to the role of biological treatment on cholangiocarcinoma. This situation calls for well-designed randomized trials, and international cooperation as well...

Improving the sludge disintegration efficiency of sonication by combining with alkalization and thermal pre-treatment methods.

One of the most serious problems encountered in biological wastewater treatment processes is the production of waste activated sludge (WAS). Sonication, which is an energy-intensive process, is the most powerful sludge pre-treatment method. Due to lack of information about the combined pre-treatment methods of sonication, the combined pre-treatment methods were investigated and it was aimed to improve the disintegration efficiency of sonication by combining sonication with alkalization and thermal pre-treatment methods in this study. The process performances were evaluated based on the quantities of increases in soluble chemical oxygen demand (COD), protein and carbohydrate. The releases of soluble COD, carbohydrate and protein by the combined methods were higher than those by sonication, alkalization and thermal pre-treatment alone. Degrees of sludge disintegration in various options of sonication were in the following descending order: sono-alkalization > sono-thermal pre-treatment > sonication. Therefore, it was determined that combining sonication with alkalization significantly improved the sludge disintegration and decreased the required energy to reach the same yield by sonication. In addition, effects on sludge settleability and dewaterability and kinetic mathematical modelling of pre-treatment performances of these methods were investigated. It was proven that the proposed model accurately predicted the efficiencies of ultrasonic pre-treatment methods.

Deprivation of tumor bioenergetics by inhibition of multiple energy pathways has been suggested as an effective therapeutic approach for various human tumors. However, this idea has not been evaluated in glioblastoma (GBM). We hypothesized that dual inhibition of glycolysis and oxidative phosphorylation could effectively suppress GBM tumorspheres (TS). Effects of 2-deoxyglucose (2DG) and metformin, alone and in combination, on GBM-TS were evaluated. Viability, cellular energy metabolism status, stemness, invasive properties, and GBM-TS transcriptomes were examined. In vivo efficacy was tested in a mouse orthotopic xenograft model. GBM-TS viability was decreased by the combination of 2DG and metformin. ATP assay and PET showed that cellular energy metabolism was also decreased by this combination. Sphere formation, expression of stemness-related proteins, and invasive capacity of GBM-TS were also significantly suppressed by combined treatment with 2DG and metformin. A transcriptome analysis showed that the expression levels of stemness- and epithelial mesenchymal transition-related genes were also significantly downregulated by combination of 2DG and metformin. Combination treatment also prolonged survival of tumor-bearing mice and decreased invasiveness of GBM-TS. The combination of 2DG and metformin effectively decreased the stemness and invasive properties of GBM-TS and showed a potential survival benefit in a mouse orthotopic xenograft model. Our findings suggest that targeting TS-forming cells by this dual inhibition of cellular bioenergetics warrants expedited clinical evaluation for the treatment of GBM. © The Author(s) 2016.

This study was undertaken to identify the combined effect of ACNU treatment and irradiation in a rat (CD Fisher) brain tumor model, which was produced by stereotaxic inoculation of F-98 or D-74 glioma clone cells. In the first series using F-98, the median survival time of the controls was 38 days. ACNU alone (7 mg/kg x 3) on Day 5, 6 and 7 following tumor cell inoculation resulted in 45 days, a single dose of irradiation alone (1,500 rads) on Day 8 produced 45 days and the combined treatment resulted in 58 days with a 28.9% increased life span (%ILS). In the second series using D-74, the median survival time of the control group was 20 days. ACNU alone (7 mg/kg x 3) showed no significant increase in survival time. A single dose of irradiation resulted in 23 days and the combined treatment in 26 days with 13.0%ILS. The third series assessed the schedule dependence of the combined treatment effects of ACNU and irradiation using D-74. The median survival time of the controls was 21 days. A single dose of ACNU (20 mg/kg) produced no significant increase. Irradiation alone (1,500 rads) on Day 8 resulted in 26 days. Combined treatment groups receiving ACNU 1 hour and 3 days prior to irradiation showed a significant increase (31 days with 19.2%ILS and 28.5 days with 9.6%ILS, respectively). However, survival times in the groups receiving ACNU 6 or 26 hours prior to irradiation, as well as 6 hours following irradiation, were not significantly longer than those in the group of irradiation alone. No significant difference in tumor size at the time of death was noted among any of the groups. Combined use of ACNU and irradiation may have a synergistic effect on the rat brain tumor model, and this effect depends on the combination schedule. (J.P.N.)

Pain is the most common reason patients seek medical attention and pain relief has been put forward as an ethical obligation of clinicians and a fundamental human right. However, pain management is challenging because the pathophysiology of pain is complex and not completely understood. Widely used analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs) and paracetamol (acetaminophen) have been associated with adverse events. Adverse event rates are of concern, especially in long-term treatment or at high doses. Paracetamol and NSAIDs are available by prescription, over the counter, and in combination preparations. Patients may be unaware of the risk associated with high dosages or long-term use of paracetamol and NSAIDs. Clinicians should encourage patients to disclose all medications they take in a “do ask, do tell” approach that includes patient education about the risks and benefits of common pain relievers. The ideal pain reliever would have few risks and enhanced analgesic efficacy. Fixed-dose combination analgesics with two or more agents may offer additive or synergistic benefits to treat the multiple mechanisms of pain. Therefore, pain may be effectively treated while toxicity is reduced due to lower doses. One recent fixed-dose combination analgesic product combines tramadol, a centrally acting weak opioid analgesic, with low-dose paracetamol. Evidence-based guidelines recognize the potential value of combination analgesics in specific situations. The current guideline-based paradigm for pain treatment recommends NSAIDs for ongoing use with analgesics such as opioids to manage flares. However, the treatment model should evolve how to use low-dose combination products to manage pain with occasional use of NSAIDs for flares to avoid long-term and high-dose treatment with these analgesics. A next step in pain management guidelines should be targeted therapy when possible, or low-dose combination therapy or both, to achieve maximal efficacy with

To compare the effectiveness of antimicrobial photodynamic therapy (PDT), standard endodontic treatment and the combined treatment to eliminate bacterial biofilms present in infected root canals. Ten single-rooted freshly extracted human teeth were inoculated with stable bioluminescent Gram-negative bacteria, Proteus mirabilis and Pseudomonas aeruginosa to form 3-day biofilms in prepared root canals. Bioluminescence imaging was used to serially quantify bacterial burdens. PDT employed a conjugate between polyethylenimine and chlorin(e6) as the photosensitizer (PS) and 660-nm diode laser light delivered into the root canal via a 200-micro fiber, and this was compared and combined with standard endodontic treatment using mechanical debridement and antiseptic irrigation. Endodontic therapy alone reduced bacterial bioluminescence by 90% while PDT alone reduced bioluminescence by 95%. The combination reduced bioluminescence by >98%, and importantly the bacterial regrowth observed 24 hours after treatment was much less for the combination (Ptreatment. Bioluminescence imaging is an efficient way to monitor endodontic therapy. Antimicrobial PDT may have a role to play in optimized endodontic therapy. (c) 2006 Wiley-Liss, Inc.

Phentermine is an anorexigenic agent, which is approved for the short-term treatment of obesity, while topiramate is approved for nonweight loss indications – seizure disorders and migraine prophylaxis. The amount of weight loss achieved with combination therapy is of a greater magnitude than what could be achieved with either agent alone. Adverse events that occur with the combination therapy are in line with the known side effect profiles of the constituent drugs; teratogenicity, a slight increase in heart rate, psychiatric and cognitive adverse effects, and metabolic acidosis are concerns.

Aluko, Olufemi Oludare; Sridhar, Mkc

2014-01-01

The removal of pollutants in landfill leachate was investigated using constructed wetlands, a trickling filter, alum flocculation and coagulation, and a sequencing batch reactor in various combinations. Thirteen combined operations were investigated involving three out of the four unit treatment methods in series. The study was conducted because unit operations, though achieved reductions in pollutants concentrations had effluent values above the national regulatory guideline values. The suspended solids of effluents were permissible in most treatment processes, while reductions in 5-day biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and ammonia (NH3) of leachates ranged from 80% to 97%; 86% to 97% and 92% to 98% respectively. However, there were significant increases in nitrate (85%) and dissolved oxygen of treatment (218%). In addition, the characteristics of the recommended treatment sequence, involving constructed wetlands, alum and trickling filter produced effluents with reductions in colour (97%), alkalinity (97%), BOD (97%), COD (97%) and NH3 (98%), and in metals, except nickel (29% reduction from the influent values). The recommended treatment combination is suitable for effective leachate management at the landfill. The cost of constructing and operating the recommended treatment combination at the facility, for 5 years, would be NGN6,009,750.00 ($38,036.39). The performance should be monitored on site prior to full adoption if effluent characteristics remain consistently low over dry and wet seasons.

This study aimed to investigate the efficacy of combined atorvastatin calcium and methylprednisolone for the treatment of multiple sclerosis relapse. Patients with multiple sclerosis (MS) at the relapse phase were randomized to receive either combined treatment of atorvastatin calcium and methylprednisolone (n = 19) or methylprednisolone alone (n = 19). Expanded Disability Status Scale (EDSS) was administered at baseline, 1 week, 2 weeks, 4 weeks, 3 months, and 6 months after treatment initiation. The number and volume of brain lesions were evaluated using magnetic resonance imaging at baseline and 6 months. The levels of IL-13, IL-35, IFN-γ, and IL-10 in the cerebrospinal fluid were examined using the enzyme-linked immunosorbent assay method. There was no significant difference in EDSS scores at 1, 2, and 4 weeks. At 3 and 6 months, the combined treatment group showed significantly lower EDSS scores than the monotherapy group (P atorvastatin calcium and methylprednisolone can improve the outcomes of MS relapse compared with glucocorticosteroid alone.

Combination treatment of mice with misonidazole (0.5 mg/g body wt.) and hyperthermia (41.5/sup o/C for 45 mins.) produced dramatic radiosensitization in hypoxic BP-8 murine sarcoma cells. The dose modifying factor (DMF: 4.3) was such that hypoxic BP-8 cells subjected to combination therapy became more radiosensitive than untreated, fully oxygenated cell populations. In contrast, radiosensitization by combination treatment was comparatively minor or completely absent in normal body tissues such as skin (DMF: 1.57), intestine (DMF: 1.0), and bone marrow (DMF: 1.0). These results suggest that simultaneous administration of misonidazole and hyperthermia may prove an effective adjuvant to conventional clinical radiation therapy

Various treatment modalities are available for management of melasma, ranging from topical and oral to chemical peeling, but none is promising alone. Very few studies are available regarding efficacy of combination of topical treatment with chemical peeling. Combination of chemical peeling and topical regimen can be a good treatment modality in the management of this recalcitrant disorder. To assess the efficacy of combination of topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling in the treatment of melasma in Indian patients. Forty Indian patients of moderate to severe epidermal variety melasma were divided into two groups of 20 each. One Group i.e. peel group received topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling and other group i.e. control group received topical regimen (2% hydroquinone, 1% hydrocortisone, 0.05% tretinoin). There was an overall decrease in MASI from baseline in 24 weeks of therapy in both the groups (P value peel with topical regimen showed early and greater improvement than the group which was receiving topical regimen only. This study concluded that combining topical regimen (2% hydroquinone, 1% hydrocortisone and 0.05% tretinoin) with serial glycolic acid peeling significantly enhances the therapeutic efficacy of glycolic acid peeling. The combination of glycolic acid peeling with the topical regimen is a highly effective, safe and promising therapeutic option in treatment of melasma.

Dry seeds of diploid barley were subjected to mutagenic treatments of sodium azide, gamma rays and EMS alone or in combination. Damage (reduction in seedling height, plant height and fertility), the frequency of chimeras in the M1 generation, and the frequency of chlorophyll-deficient mutations as well as morphological mutations in the M2 generation induced by combined treatments were greater than those by either of the single treatments. Synergistic increase in the frequency of chimeras, chlorphyll-deficient mutations and morphological mutations were observed in both sodium azide post-irradiation treatments and pre-EMS treatments; interaction among the mutagens in the treatment combinations on M1 damage was generally subtractive. An 8- to 16-hr soaking period of irradiated seeds in distilled water prior to sodium azide treatment significantly increased chlorophyll mutation frequency, as compared to that from the non-soaking treatment. Damage and frequency of chimeras, chlorophyll mutations and morphological mutations were consistently reduced by the soaking treatment in sodium azide plus EMS treatments. (author)

Dry rice seeds of 3 cvs and 2 lines have been irradiated (Co 60 , 10 krad) and treated with 0.0012% sodium azide (NaN 3 ) and 0.2% ethylmethanesulfonate (EMS) in definite combinations. It is found that chlorophyll mutations are less frequent after single gamma irradiation. Sodium azide produces a higher percentage of mutations than EMS. Highest mutation frequency has been observed following combined treatment with gamma rays and chemical mutagens. The combined treatment has resulted in a considerably higher mutation effect than the theoretically expected one in the lines Nora and Mega, and in cv. Krasnodarski 424. Highest mutation spectrum has been found in cv. Krasnodarski 424 and in Nora line following combined treatment. 1 tab., 5 figs., 20 refs

Full Text Available The results of the pilot study of combined treatment for non-resectable cholangiocarcinoma complicated with obstructive jaundice are represented this paper. Method included percutaneous transhepatic biliary drainage, endoscopic fluorescence diagnosis, photodynamic therapy of tumor stricture, and stenting of bile ducts. Fourteen patients who underwent the treatment in the surgery department clinic of I.M. Sechenov First Moscow State Medical University were enrolled in the study. Fluorescence diagnosis and photodynamic therapy were carried out using photosensitizers photosens (0.5 mg/kg, fotolon (1 mg/kg, and radachlorin (1 mg/kg. The average light dose for one session was 115±5 J/cm2. Fluorescence diagnosis using endoscopic video-fluorescence system for endoscopy and minimally invasive surgery allowed to obtain videoassisted fluorescence image of the tumor and to measure level of photosensitizer fluorescence in tumor in all patients. Malignant tumor was confirmed by morphological study in 12 patients, biopsy of material for morphological study failed in 2 patients with Klatskin tumor. The preliminary results of combined minimally invasive treatment were assessed as promising. The survival time in 4 patients after treatment accounted for 21, 17, 13 and 11 months, respectively. For now 5 patients are under follow-up. Follow-up periods are 13 and 19 months in 2 of them and from 4 to 6 months in 3 of them. Five patients with multiple distant metastases before the treatment died in 3±1 months after therapy. The average lifetime in the treatment group is 9.5 months up to date, however the duration is expected to belonger because 5 of 14 patients are alive.

There are two purposes of using combined chemotherapy and radiotherapy in the treatment of cancers. One is to suppress distant metastasis, especially micrometastasis; the other is to improve localized control. As a trial of the utility of the former, systemic chemotherapy with CDDP and 5 FU was given successively with radiotherapy to treat nasopharyngeal cancer. The survival rate was significantly improved compared with historical control cases. The main reason for this effectiveness was the improvement of localized control. The suppression of distant metastasis is the subject of future research. As a trial of the utility of the latter, a super-selective intraarterial chemotherapy with CBDCA combined with radiotherapy was used to head and neck localized progressive cancers. The control of localized cancer was remarkably effective. This treatment is considered to be especially suitable for locally advanced tongue cancer and cancer of the root of the tongue. (author)

In a double-blind, randomized, controlled study, the effectiveness of treatment with a combination of Benfotiamine (an Allithiamine, a lipid-soluble derivative of vitamin B1 with high bioavailability) plus vitamin B6/B12 on objective parameters of neuropathy was studied over a period of 12 weeks on 24 diabetic patients with diabetic polyneuropathy. The results showed a significant improvement (p = 0.006) of nerve conduction velocity in the peroneal nerve and a statistical trend toward improvement of the vibration perception threshold. Long-term observation of 9 patients with verum over a period of 9 months support the results. Therapy-specific adverse effects were not seen. The results of this double-blind investigation, of the long-term observation and of the reports in the literature support the contention that the neurotropic benfotiamine-vitamin B combination represents a starting point in the treatment of diabetic polyneuropathy.

Full Text Available Bo AhrénDepartment of Clinical Sciences, Division of Medicine, Lund University, Lund, SwedenAbstract: Inhibition of dipeptidyl peptidase-4 (DPP-4 as a novel therapy for type 2 diabetes is based on prevention of the inactivation process of bioactive peptides, the most important in the context of treatment of diabetes of which is glucagon-like peptide-1 (GLP-1. Most clinical experience with DPP-4 inhibition is based on vildagliptin (GalvusR, Novartis and sitagliptin (JanuviaR, Merck. These compounds improve glycemic control both in monotherapy and in combination with other oral hyperglycemic agents. Both have also been shown to efficiently improve glycemic control when added to ongoing metformin therapy in patients with inadequate glycemic control. Under that condition, they reduce HbA1c levels by 0.65%–1.1% (baseline HbA1c 7.2–8.7% in studies up to 52 weeks of duration in combination versus continuous therapy with metformin alone. Sitagliptin has also been examined in initial combination therapy with metformin have; HbA1c was reduced by this combination by 2.1% (baseline HbA1c 8.8% after 24 weeks of treatment. Both fasting and prandial glucose are reduced by DPP-4 inhibition in combination with metformin in association with improvement of insulin secretion and insulin resistance and increase in concentrations of active GLP-1. The combination of DPP-4 inhibition and metformin has been shown to be highly tolerable with very low risk of hypoglycemia. Hence, DPP-4 inhibition in combination with metformin is an efficient, safe and tolerable combination therapy for type 2 diabetes.Keywords: DPP-4 inhibition, sitagliptin, vildagliptin, metformin, type 2 diabetes

Combined radiological and chemical treatment of carcinomas of the anus

Schuck, U.

1988-01-01

A combination of radiotherapy and chemotherapy has proved effective and the toxic reactions to this treatment generally remain within tolerable limits, as there is no need to inflict major wounds and the anal functions can largely be maintained. The tumour remission seen here is more rapid and more radical than that achieved by the simple use of irradiation. This means that the radiation dose may safely be reduced without thereby marring the success of treatment. Cytostatic drugs alone show no great effectiveness against anal carcinomas and are beneficial only in connection with radiation treatment. Acute local reactions were observed in all patients, while the delayed effects seen following surgery or radiotherapy as the sole method of treatment failed to occur here. The main drawback of radiochemical treatment are hematological side-effects in the form of bone marrow depression. (VHE) [de

2013-06-01

Diuretics belong to the basic group of medicines for the treatment of hypertension and heart failure. In the case of hypertension treatment, their main indication is higher age and isolated systolic hypertension. In the case of heart failure they are used for the treatment of swellings and shortness of breath. The most frequently prescribed group of diuretics is thiazides and similar products. In patients with renal insufficiency, loop diuretics are administered. In the case of hypertension, diuretics are mainly used in the combination treatment. The most frequently used diuretic in combination is again hydrochlorothiazide, which is combined with reninangiotensin system blockers. It is mainly the combination of an ACE inhibitor + indapamide that seems to be modern and promising, and it is, on the basis of large clinical trials, recommended also for diabetics (ADVANCE) or for secondary prevention following a cerebrovascular accident (PROGRESS) or for the elderly (HYVET). Also a combination of two diuretics is popular -  mainly hydrochlorothiazide + amiloride. A combination of a betablocker and diuretic is less suitable.

Insomnia and nightmares are hallmarks of posttraumatic stress disorder (PTSD). Sleep disturbances in PTSD negatively impact clinical course and functioning. In this open clinical trial, the preliminary effects of a combined treatment for insomnia and nightmares in combat veterans with PTSD were assessed. Ten combat veterans participated in a 10-session group treatment combining cognitive-behavioral therapy for insomnia with exposure, rescripting, and relaxation therapy. Participants maintained daily sleep and dream diaries and completed self-report measures of sleep quality and PTSD symptoms pre- and posttreatment. Participants reported improvements in sleep and nightmares following treatment. Future research using controlled designs to evaluate this treatment is warranted.

Purpose: Radiobiological modeling was used to explore optimum combination strategies for treatment of disseminated malignancies of differing radiosensitivity and differing patterns of metastatic spread. The purpose of the study was to derive robust conclusions about the design of combination strategies that incorporate a targeting component. Preliminary clinical experience of a neuroblastoma treatment strategy, which is based upon general principles obtained from modelling, is briefly described. Methods and Materials: The radiobiological analysis was based on an extended (dose-rate dependent) formulation of the linear quadratic model. Radiation dose and dose rate for targeted irradiation of tumors of differing size was in part based on microdosimetric considerations. The analysis was applied to several tumor types with postulated differences in the pattern of metastatic spread, represented by the steepness of the slope of the relationship between numbers of tumors present and tumor diameter. The clinical pilot study entailed the treatment of five children with advanced neuroblastoma using a combination of 131 I metaiodobenzylguanidine (mIBG) and total body irradiation followed by bone marrow rescue. Results: The theoretical analysis shows that both intrinsic radiosensitivity and pattern of metastatic spread can influence the composition of the ideal optimum combination strategy. High intrinsic radiosensitivity generally favors a high proportion of targeting component in the combination treatment, while a strong tendency to micrometastatic spread favors a major contribution by total body irradiation. The neuroblastoma patients were treated using a combination regimen with an initially low targeting component (2 Gy whole body dose from targeting component plus 12 Gy from total body irradiation). The treatment was tolerable and resulted in remissions in excess of 9 months in each of these advanced neuroblastoma patients. Conclusions: Radiobiological analysis, which

This work reports the treatment of a mature landfill leachate through the application of chemical-based treatment processes in order to achieve the discharge legal limits into natural water courses. Firstly, the effect of coagulation/flocculation with different chemicals was studied, evaluating the role of different initial pH and chemicals concentration. Afterwards, the efficiency of two different advanced oxidation processes for leachate remediation was assessed. Fenton and solar photo-Fenton processes were applied alone and in combination with a coagulation/flocculation pre-treatment. This physicochemical conditioning step, with 2 g L(-1) of FeCl3 · 6H2O at pH 5, allowed removing 63% of COD, 80% of turbidity and 74% of total polyphenols. Combining the coagulation/flocculation pre-treatment with Fenton reagent, it was possible to reach 89% of COD removal in 96 h. Moreover, coagulation/flocculation combined with solar photo-Fenton revealed higher DOC (75%) reductions than single solar photo-Fenton (54%). In the combined treatment (coagulation/flocculation and solar photo-Fenton), it was reached a DOC reduction of 50% after the chemical oxidation, with 110 kJ L(-1) of accumulated UV energy and a H2O2 consumption of 116 mM. Toxicity and biodegradability assays were performed to evaluate possible variations along the oxidation processes. After the combined treatment, the leachate under study presented non-toxicity but biodegradability increased. Copyright © 2014 Elsevier B.V. All rights reserved.

Immunomodulatory drugs (IMiDs) thalidomide, lenalidomide (Len) and pomalidomide trigger anti-tumor activities in multiple myeloma (MM) by targetting cereblon and thereby impacting IZF1/3, c-Myc and IRF4. Histone deacetylase inhibitors (HDACi) also downregulate c-Myc. We therefore determined whether IMiDs with HDACi trigger significant MM cell growth inhibition by inhibiting or downregulating c-Myc. Combination treatment of Len with non-selective HDACi suberoylanilide hydroxamic acid or class-I HDAC-selective inhibitor MS275 induces synergic cytotoxicity, associated with downregulation of c-Myc. Unexpectedly, we observed that decreased levels of cereblon (CRBN), a primary target protein of IMiDs, was triggered by these agents. Indeed, sequential treatment of MM cells with MS275 followed by Len shows less efficacy than simultaneous treatment with this combination. Importantly ACY1215, an HDAC6 inhibitor with minimal effects on class-I HDACs, together with Len induces synergistic MM cytotoxicity without alteration of CRBN expression. Our results showed that only modest class-I HDAC inhibition is able to induce synergistic MM cytotoxicity in combination with Len. These studies may provide the framework for utilizing HDACi in combination with Len to both avoid CRBN downregulation and enhance anti-MM activities

Escobar-Morreale, Héctor F; Botella-Carretero, José I; Morreale de Escobar, Gabriella

2015-01-01

At present, the drug of choice for the treatment of hypothyroidism is levothyroxine sodium, even though the thyroid gland secretes both thyroxine and 3',3,5-triiodothyronine; the latter is the more active of the two at the cellular level because of its higher affinity for the nuclear thyroid hormone receptors. To date, combined levothyroxine plus liothyronine treatment for hypothyroidism has been evaluated in 15 clinical trials in humans. In two studies, combined therapy seemed to have beneficial effects on mood, quality of life, and psychometric performance of patients, compared with levothyroxine alone; in some of these studies, the patients preferred levothyroxine plus liothyronine combinations. This preference should be balanced against the possibility of adverse events resulting from the addition of liothyronine to levothyroxine. Until clear advantages of levothyroxine plus liothyronine are demonstrated, the administration of levothyroxine alone should remain the treatment of choice for replacement therapy of hypothyroidism.

Objective: To investigate the clinical value for treatment of diabetic foot with PTA and PTA combined cinepazide maleate. Methods: In 24 cases of diabetic associated vascular disease of lower limb, 12 cases were treated with PTA and other 12 cases were treated with PTA combined cinepazide maleate. We analysed and compared clinical effects before and after the procedure, together with 3 months follow up. Results: In patients treated with PTA, the clinical symptom scores of posttreatment and follow-up decreased; ABI and TcPO 2 increased significantly. The clinical symptom score and ABI of follow-up remained, stable, but TcPO 2 decreased significantly. Control angiography showed improvement in degree of vascular stenosis and peripheral staining of 11 patients after treatment. The vascular patency remained in 12 patients and the peripheral staining decreased in 7 patients on follow-up. In patients treated with PTA combined cinepazide maleate, the clinical symptom score, ABI and TcPO 2 after treatment and on follow-up showed no significant changes compared with those in patients treated by PTA. Control angiography showed that the degree of vascular stenosis and peripheral staining were improved in 12 patients after treatment. The vascular patency was maintained and peripheral staining was improved on follow-up. Before and after treatment, there were no significant differences in clinical symptom score, ABI and TcPO 2 between patients treated with PTA and PTA combined cinepazide maleate, however, there were significant differences in clinical symptom score and TcPO 2 on follow-up. Conclusion: PTA can significantly improve clinical symptom of diabetic foot and the application of cinepazide maleate is a beneficial and necessary supplement. PTA combined cinepazide maleate can be taken as one of the conventional treatment plans for diabetic foot. (authors)

Two repurposed medications have been proposed to treat cocaine abuse. Progesterone, a gonadal hormone, and atomoxetine, a medication commonly used to treat attention deficit/hyperactivity disorder, have both been separately shown to reduce cocaine self-administration and reinstatement (i.e., relapse). The goal of the present study was to examine sex differences in the individual effects of PRO and ATO as well as the combination PRO+ATO treatment on cocaine (COC), caffeine (CAF), and/or cue-primed reinstatement of cocaine-seeking. Adult male and female Wistar rats lever-pressed under a FR 1 schedule for cocaine infusions (0.4mg/kg/inf). After 14 sessions of stable responding in daily 2-h sessions, rats underwent a 21-day extinction period when no drug or drug-related stimuli were present. Rats were then separated into four groups that received PRO (0.5mg/kg) alone (PRO+SAL), ATO (1.5mg/kg) alone (VEH+ATO), control (VEH+SAL) or combination (PRO+ATO) treatments prior to the reinstatement condition. Reinstatement of cocaine-seeking to cues and/or drug injections of cocaine or caffeine was tested after extinction. During maintenance, females self-administered more cocaine than males, but no sex differences were seen during extinction. Females showed greater cocaine-seeking than males after a CAF priming injection. Individual treatment with ATO did not decrease reinstatement under any priming condition; however, the combination treatment decreased cocaine-seeking under the COC+CUES priming condition in males, and both PRO alone and the combination treatment decreased cocaine-seeking in the CAF+CUES condition in females. Overall, PRO alone was only effective in reducing reinstatement in females, while the combination treatment was consistently effective in reducing reinstatement in both sexes.

Therapeutic Advances using Combinational Therapy in the Treatment of Glioblastoma

DEFF Research Database (Denmark)

Staberg, Mikkel

2017-01-01

Glioblastoma is the most malignant brain tumor in adults. Median survival is only about 15 months despite aggressive treatment, consisting of surgery followed by radio- and chemotherapy, stressing the need for new therapies. Development of glioblastoma is thought to be a result of both genetic...... and epigenetic alterations, ultimately leading to oncogenic transformation of normal glia cells. Several features are suggested to give rise to the poor prognosis of glioblastoma including treatment resistance, a high degree of abnormal blood vessels, and high heterogeneity, both within the single tumor and from...... patient to patient. Thus, investigations are needed to identify the genetic-molecular alterations that glioblastoma tumors depend on in order to overcome treatment and regrow after initial surgery. The findings presented in this thesis illustrate the promising potential of combinational treatments...

Fixed-functional appliance treatment combined with growth hormone therapy.

Jung, Min-Ho

2017-09-01

The purpose of this study was to illustrate the effects of growth hormone (GH) therapy and fixed functional appliance treatment in a 13-year-old Class II malocclusion patient without GH deficiency. GH has been shown to effectively increase endochondral growth and induce a more prognathic skeletal pattern. Although a major concern in Class II retrognathic patients is chin deficiency, long-term studies have shown that the mandibular growth enhancement effects of functional appliances are clinically insignificant. This case report demonstrates that the mandible grew significantly during fixed functional appliance treatment combined with GH therapy, with stable results during 2 years 11 months of retention. More studies are needed to evaluate GH therapy as a supplement in Class II treatment. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

Deng, Dongyang; Lin, Lian-Shin

2013-01-01

This study examined the feasibility of the combined treatment of field-collected acid mine drainages (AMD, pH = 4.2 ± 0.9, iron = 112 ± 118 mg/L, sulfate = 1,846 ± 594 mg/L) and municipal wastewater (MWW, avg. chemical oxygen demand (COD) = 234-333 mg/L) using a two-stage process. The process consisted of batch mixing of the two wastes to condition the mixture solutions, followed by anaerobic biological treatment. The mixings performed under a range of AMD/MWW ratios resulted in phosphate removal of 9 to ∼100%, the mixture pH of 6.2-7.9, and COD/sulfate concentration ratio of 0.05-5.4. The biological treatment consistently removed COD and sulfate by >80% from the mixture solutions for COD/sulfate ratios of 0.6-5.4. Alkalinity was produced in the biological treatment causing increased pH and further removal of metals from the solutions. Scanning electron microscopy of produced sludge with energy dispersion analysis suggested chemical precipitation and associated adsorption and co-precipitation as the mechanisms for metal removal (Fe: >99%, Al: ∼100%, Mn: 75 to ∼100%, Ca: 52-81%, Mg: 13-76%, and Na: 56-76%). The study showed promising results for the treatment method and denoted the potential of developing innovative technologies for combined management of the two wastes in mining regions.

Effect of combined mutagenic treatments on sensitivity and mutation frequency in rice

Gopinathan Nair, V.

1977-01-01

Rice seeds were subjected to two sets of combination treatments of radiations and NMH. The effects of mutagenic treatments in the M 1 and M 2 generations were recorded and discussed. Mutation frequencies estimated as number of mutations per 100 M 1 years were not higher than the values expected on the basis of additive effects. When estimated as number of mutants per 100 M 2 plants, the frequencies revealed more than additive effects. The synergistic effect on mutant frequencies was due to increase in the segregation ratio of mutants. This effect was more pronounced at the higher dose combinations of fast neutrons and NMH.

To investigate the efficiency of piracetam and acyclovir in treating sudden hearing loss. Eightyone patients (44 males, 37 females; mean age 40.4 year; range 18 to 72 years) who had treatment between January 2002 and December 2006 with diagnosis of idiopathic sudden hearing loss were evaluated retrospectively. These patients were divided into four groups according to the treatment they received. The patients who had combined treatment constituted the first group; those who had combined treatment and piracetam the second; those who had combined treatment and acyclovir the third; those who had combined treatment, acyclovir, and piracetam the fourth group. For the four treatment groups, in the pre-and post-treatment (10th day) evaluation of the treatment efficiency made by calculation of the hearing thresholds in 250-8000 Hz frequencies, no significant difference between the groups was determined (p>0.05). No additional benefit was obtained with acyclovir and piracetam in treatment.

Treatment was studied of oro-facial epidermoid carcinoma by combined chemo- and radiotherapy and eventual surgery. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexate (MTX), a combined cytostatic program was developed alternating two cytostatic drugs, viz., MTX and Bleomycin (BLM). The usefulness of chemotherapy and its inclusion in the treatment of epidermoid carcinoma in the oro-facial region was found justified for combined therapy. The selected intraarterial administration, however, is not suitable for routine application. For this reason, the combination irradiation or surgical therapy with chemotherapy was adopted.

Full Text Available Mario Cazzola,1 Andrea Segreti,1 Maria Gabriella Matera2 1Department of System Medicine, University of Rome 'Tor Vergata', Rome, Italy; 2Department of Experimental Medicine, Second University, Naples, Italy Abstract: An increasing body of evidence suggests that the long-acting muscarinic antagonist (LAMA/long-acting β2-agonist (LABA combination appears to play an important role in maximizing bronchodilation, with studies to date indicating that combining different classes of bronchodilators may result in significantly greater improvements in lung function compared to the use of a single drug, and that these combinations are well tolerated in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD. An inhaled, fixed-dose combination of two 24-hour bronchodilators, the LAMA umeclidinium and the LABA vilanterol, is under development as a once-daily treatment for COPD. The efficacy of both mono-components has already been demonstrated. The information currently available suggests that umeclidinium/vilanterol is an effective once-daily dual bronchodilator fixed-dose combination in the treatment of COPD. However, it remains to be seen if it compares favorably with current therapies. Moreover, the question remains whether umeclidinium/vilanterol fixed-dose combination, which significantly improves FEV1, is also associated with improvements in other outcome measures that are important to COPD patients.

Full Text Available Osteoarthritis (OA is the most common form of joint damage and a major cause of morbidity and disability. The significant increase in the incidence is due to the rapid aging of the population and the pandemic of obesity. The main clinical symptoms of OA are pain and deformation of joints, leading to functional impairment. OA treatment requires not only accurate diagnosis, but also estimation of the prevalence and severity of articular damage, the general health status of the patient and the presence of comorbid conditions for the correct choice of treatment, and possibly a combination thereof. Proven effectiveness of chondroitin sulfate and glucosamine hydrochloride alone, created the preconditions for the development of complex products. The effectiveness of this combination is supported by experimental and clinical data.

Full Text Available Introduction: Degenerative joint disease, which is standardized in Europe by the name of arthrosis or osteoarthrosis, while in the Anglo-Saxon literature is in use for a long time by the name of osteoarthritis (OA although this is not a classical inflammation,is the most common joint disease in general and the most common cause of functional damage of the musculoskeletal system. Recently, the term osteoarthritisappears more frequently in domestic literature. Arthroses are degenerative joint diseases with progressive character, also one of the most frequent diseases in orthopedics. The disease fi rst affects the articular cartilage, then the bony edges of the articular surfaces, and then the articular lining.Methods: Retrospective analysis and evaluation of data of treated patients, with the "Praxis" physical treatment during the period of time from 2000 to the end of 2010 on a sample of 79 patients,valorized the efficacy of Praxis treatment. The  correlation of these results, with valorisation of the efficacy of standard physical treatment in clinics D.Z. " Novi Grad " on a sample of 81 patients, during the period of time from 2000 to the end of 2010, a statistical analysis was performed for comparing the effi cacy of the two methods.Results: There is a functional difference after therapy of bilateral gonarthrosis in clinics D.Z. "Novi Grad" and "Praxis" with statistical reliability.Conclusion: A combined approach in the treatment of knee arthrosis has a wider range of treatment procedures, comprehensively approaches to the problem and gives better results, so we can say that this method has priority compared to the standard approach to the knee arthrosis treatment.

Treatment for snoring. Combined weight loss, sleeping on side, and nasal spray.

Science.gov (United States)

Braver, H M; Block, A J; Perri, M G

1995-05-01

We sought to find a combination of noninvasive treatments for snoring by adding weight loss to previously studied treatments, including the combination of sleeping on one's side and using a decongestant nasal spray. Twenty asymptomatic men who snore heavily were studied previously on a control night and on a night when they slept on their side and used a nasal spray. With these two treatments, minor improvements in apnea/hypopnea index (AHI) were seen, but no improvement occurred in snoring frequency. Nineteen of these subjects subsequently completed a 6-month weight loss program, and 12 lost weight. These 19 subjects comprise the study population of this report. At the conclusion of the weight loss program, a repeated sleep study was done from which the effect of adding weight loss to the two previously studied treatments could be assessed. Those 12 subjects who lost any amount of weight showed a very mild reduction in snores per hour from 328 using two modalities of treatment to 232 per hour with the addition of weight loss (p = 0.15). The nine subjects who lost > or = 3 kg reduced the number of snores per hour from 320 to 176 (p = 0.0496). Three subjects losing an average of only 7.6 kg showed virtual elimination of snoring after weight loss. Subjects who gained weight had no improvement in snoring. Weight loss added to the other two modalities of treatment had no effect on the AHI. In most cases, the combination of weight loss, sleeping on one's side, and the administration of a nasal decongestant significantly reduces the frequency of snoring in asymptomatic men who snore heavily. The major effect appears to be related to weight loss.

Yu Gil Park

2017-05-01

Full Text Available BackgroundPlatelet-rich plasma (PRP contains high concentrations of growth factors involved in wound healing. Hydrogel is a 3-dimensional, hydrophilic, high-molecular, reticular substance generally used as a dressing formulation to accelerate wound healing, and also used as a bio-applicable scaffold or vehicle. This study aimed to investigate the effects of PRP and hydrogel on wound healing, in combination and separately, in an animal wound model.MethodsA total of 64 wounds, with 2 wounds on the back of each nude mouse, were classified into 4 groups: a control group, a hydrogel-only group, a PRP-only group, and a combined-treatment group. All mice were assessed for changes in wound size and photographed on scheduled dates. The number of blood vessels was measured in all specimens. Immunohistochemical staining was used for the analysis of vascular endothelial growth factor (VEGF expression.ResultsDifferences in the decrease and change in wound size in the combined-treatment group were more significant than those in the single-treatment groups on days 3, 5, 7, and 10. Analysis of the number of blood vessels through histological examination showed a pattern of increase over time that occurred in all groups, but the combined-treatment group exhibited the greatest increase on days 7 and 14. Immunohistochemical staining showed that VEGF expression in the combined-treatment group exhibited its highest value on day 7.ConclusionsThis experiment demonstrated improved wound healing using a PRP–hydrogel combined treatment compared to either treatment individually, resulting in a decrease in wound size and a shortening of the healing period.

Intra-arterial and intra-venous chemotherapy combined with radiation in the treatment of brain tumours

International Nuclear Information System (INIS)

Watne, K.

1992-01-01

The present investigations were undertaken to study the effect of combining different modalities of chemotherapy with radiation in post-operative treatment of brain tumours. The conclusions and clinical implication of the investigations are as follows: The combination of combined intra-arterial chemotherapy followed by radiation leads to an increased median survival with more long term survivors in patients with anaplastic astrocytomas and in patients older than 40 years with astrocytomas. In patients with glioblastoma multiforme, this modality of treatment do not improve median survival, but an increased number of long-term survivors may be seen. Patients younger than 40 years with astrocytomas do not benefit from this modality of treatment. A parallelism exists between sensitivity to chemotherapy and response to radiotherapy. Patients who will benefit from the treatment may be selected early, normally two months after treatment start. Combining intra-arterial chemotherapy and radiation does not lead to an increased incidence of adverse CNS reactions. Specific transient abnormalities in the brain may occur during the first year after treatment and may be misinterpreted as tumour recurrence. EEG may be valuable in predicting adverse CNS reactions following treatment. Nuclear brain scan may be of valuable in selecting the patients who are in danger of developing adverse CNS reactions. Intra-arterial chemotherapy does have an effect in patients with brain tumours who have recurrent tumour after radiation.

Science.gov (United States)

The current study evaluates the effectiveness of the combined application of Peracetic acid and ultraviolet radiation as alternative disinfectant agents to the traditional chlorination of wastewater effluents. Various pathogens (E. coli, enterococci and fecal coliforms) were evaluated in the study. Four experiments were conducted using low to high PAA levels and UV dosages. E. coli and enterococci were resistant to low to moderate PAA dosage (0.5- 1 mg/L). These microbes can be removed effectively at high PAA dosage (2.5 mg/L) with 30 min contact time. Fecal coliforms were completely inactivated even at a low PAA dose of 0.7 mg/L. E. coli was more susceptible to UV disinfection than enterococci at low UV dosages. Enterococci required at least 40 mJ/cm2 for 2.5 log inactivation. In combined PAA + UV treatment, low UV intensities between 7 – 40 mJ/cm2 showed poor disinfection performance at a low PAA concentration of 1.5 mg/L. High UV intensities of 120 and 60 mJ/cm2 inactivated all the pathogens to below detection levels even at low to moderate PAA (0.7 mg/L and 1 mg/L) pretreatment concentration. Combined PAA + UV treatment at 1 mg/L (for 15 and 30 min contact time) + 120 and 60 mJ/cm2 did not show any regrowth of microbes, whereas PAA only disinfection with 15 min contact time showed regrowth of enterococci and fecal coliforms. UV only disinfection showed E. coli regrowth. • This pilot scale study was designed for providing necessary parameter optimization

Freezing process alone caused relatively low decrease in viable count of suspended spores in minced meat while it decreased the spore numbers suspended in saline solution by more than one log cycle especially in case of the Egyptian strain. An abrupt decrease in viable counts of clostridium spores was observed by application dose of 1KGY either before or after freezing followed by gradual decrease of viable counts up to 15 KGY. The synergestic effect of combined treatment was clearly obvious for spores suspended in minced meat, which usually contains protective agents which increase the resistance of microorganisms against the separate treatment of radiation of freezing especially with spores of NCTC 8798 strain. Freezing the saline suspending medium before or after irradiation after the sensitivity of clostridium spores by only small extent and gave negative synergestic effect in some treatment. The percentages of injured spores due to the combined treatment were ranged between 15-100% of the viable counts. The percentage of injured spores tended to increase as the radiation dose levels increased

Full Text Available It is estimated that one third of the world’s population is infected with Mycobacterium tuberculosis (Mtb. This astounding statistic, in combination with costly and lengthy treatment regimens make the development of therapeutic vaccines paramount for controlling the global burden of tuberculosis. Unlike prophylactic vaccination, therapeutic immunization relies on the natural pulmonary infection with Mtb as the mucosal prime that directs boost responses back to the lung. The purpose of this work was to determine the protection and safety profile over time following therapeutic administration of our lead Mtb vaccine candidate, ID93 with a synthetic TLR4 agonist (glucopyranosyl lipid adjuvant in a stable emulsion (GLA-SE, in combination with rifampicin, isoniazid, and pyrazinamide (RHZ drug treatment. We assessed the host inflammatory immune responses and lung pathology 7–22 weeks post infection, and determined the therapeutic efficacy of combined treatment by enumeration of the bacterial load and survival in the SWR/J mouse model. We show that drug treatment alone, or with immunotherapy, tempered the inflammatory responses measured in brochoalveolar lavage fluid and plasma compared to untreated cohorts. RHZ combined with therapeutic immunizations significantly enhanced TH1-type cytokine responses in the lung over time, corresponding to decreased pulmonary pathology evidenced by a significant decrease in the percentage of lung lesions and destructive lung inflammation. These data suggest that bacterial burden assessment alone may miss important correlates of lung architecture that directly contribute to therapeutic vaccine efficacy in the preclinical mouse model. We also confirmed our previous finding that in combination with antibiotics therapeutic immunizations provide an additive survival advantage. Moreover, therapeutic immunizations with ID93/GLA-SE induced differential T cell immune responses over the course of infection that correlated

Endometriosis is the second most common benign female genital disease after uterine myoma. This review discusses the management of individual patients. This should take into account the severity of the disease and whether the patient desires to have children. Particular emphasis is laid on the anatomical intersections which, when injured, can lead to persistent damage of the anterior, middle or posterior compartment and are not infrequently the cause of urological and urogynaecological follow-up measures. Typical symptoms of endometriosis include chronic pelvic pain, subfertility, dysmenorrhoea, deep dyspareunia, cyclical bowel or bladder symptoms (e. g. dyschezia, bloating, constipation, rectal bleeding, diarrhoea and haematuria), abnormal menstrual bleeding, chronic fatigue and low back pain. Approx. 50 % of all female teenagers and up to 32 % of all women of reproductive age who have been operated for chronic pelvic pain or dysmenorrhoea suffer from endometriosis. The time interval between the first unspecific symptoms and the medical diagnosis of endometriosis is about 7 years. This is caused not only by the non-specific nature of the symptoms but also by the frequent lack of awareness on the part of the cooperating disciplines with which the patients have first contact. As the pathogenesis of endometriosis is not clearly understood, causal treatment is still impossible. Treatment options include expectant management, analgesia, hormonal medical therapy, surgical intervention and the combination of medical treatment before and/or after surgery. The treatment should be as radical as necessary and as minimal as possible. The recurrence rate among treated patients lies between 5 % and > 60 % and is very much dependent on integrated management and surgical skills. Consequently, to optimise the individual patient's treatment, a high degree of interdisciplinary cooperation in diagnosis and treatment is crucial and should be reserved to appropriate

To analyze the clinical effect of tamsulosin and Solifenacin in the treatment of benign prostatic hyperplasia in combination with overactive bladder and its safety. Another objective was to investigate the clinical effect and safety of mega dose of tamsulosin in the treatment of benign prostatic hyperplasia in combination with overactive bladder. One hundred and twenty-four patients who were admitted to the Dept. of Urology at Binzhou People's Hospital, , China with confirmed benign prostatic hyperplasia (BPH) with overactive bladder were randomly divided into two groups. Sixty-two patients in the control group were treated with tamsulosin, while sixty-two patients in the observation group were treated with tamsulosin in combination with solifenacin. The treatment of both groups lasted for 12 weeks. The effect and adverse reaction were compared between the two groups. The international prostate symptom score (IPSS), quality of life (QOL), and overactive bladder symptom score (OABSS), Q max , pulmonary vascular resistance (PVR), daytime urination frequency, urgent urination frequency, urge urinary incontinence frequency and night urinary frequency of both groups improved after treatment, and the difference had statistical significance (P0.05). Treating benign prostatic hyperplasia in combination with overactive bladder with tamsulosin in combination with solifenacin is more effective than tamsulosin, without significantly increasing adverse reactions. Thus the therapy is worth clinical promotion.

Selective release characteristics of phosphorus and nitrogen from waste activated sludge (WAS) were investigated during combined thermal and alkali treatment. Alkali (0.001-1.0N NaOH) treatment and combined thermal-alkali treatment were applied to WAS for releasing total P(T-P) and total nitrogen(T-N). Combined thermal-alkali treatment released 94%, 76%, and 49% of T-P, T-N, and COD, respectively. Release rate was positively associated with NaOH concentration, while temperature gave insignificant effect. The ratio of T-N and COD to T-P that released with alkali treatment ranged 0.74-0.80 and 0.39-0.50, respectively, while combined thermal-alkali treatment gave 0.60-0.90 and 0.20-0.60, respectively. Selective release of T-P and T-N was negatively associated with NaOH. High NaOH concentration created cavities on the surface of WAS, and these cavities accelerated the release rate, but reduced selectivity. Selective release of P and N from sludge has a beneficial effect on nutrient recovery with crystallization processes and it can also enhance methane production. Copyright © 2015 Elsevier Ltd.

Recently, a new treatment, which is a combination of two direct-acting antiviral agents, ledipasvir 90 mg (anti-NS5A and sofosbuvir 400 mg (anti-NS5B, has been approved in the US and the European Union for the treatment of chronic hepatitis C viral infection. In Phase III trials among chronic hepatitis C virus genotype 1 monoinfected (treatment-naïve, treatment-experienced, and with advanced liver disease or posttransplant patients and HIV–hepatitis C virus coinfected patients, the ledipasvir-sofosbuvir fixed-dose combination is associated with a higher rate of sustained virologic response at 12 weeks after therapy has ceased. According to preliminary data, the ledipasvir-sofosbuvir combination also may be effective against hepatitis C genotype 4 virus infection. The ledipasvir-sofosbuvir combination taken orally is generally well-tolerated. Moreover, the combination treatment may suppress the effect of predictive factors of chronic hepatitis C that have historically been known to be associated with treatment failure. Thus, the fixed-dose single-tablet combination of ledipasvir-sofosbuvir offers a new era for the effective treatment of a variety of patients suffering from chronic hepatitis C virus infection.Keywords: ledipasvir, liver disease, ethnicity, DAA, HIV

Full Text Available Abstract Background In oncologic patients with metastatic spinal disease, the ideal treatment should be well tolerated, relieve the pain, and preserve or restore the neurological function. The combination of fluoroscopic guided radiofrequency ablation (RFA and kyphoplasty may fulfill these criteria. Methods We describe three pathological vertebral fractures treated with a combination of fluoroscopic guided RFA and kyphoplasty in one session: a 62-year-old man suffering from a painful L4 pathological fracture due to a plasmocytoma, a 68-year-old man with a T12 pathological fracture from metastatic hepatocellular carcinoma, and a 71-year-old man with a Th12 and L1 pathological fracture from multiple myeloma. Results The choice of patients was carried out according to the classification of Tomita. Visual analog score (VAS and Oswestry disability index (ODI were used for the evaluation of the functional outcomes. The treatment was successful in all patients and no complications were reported. The mean follow-up was 6 months. Marked pain relief and functional restoration was observed. Conclusion In our experience the treatment of pathologic spinal fractures with combined radiofrequency ablation and balloon kyphoplasty is safe and effective for immediate pain relief in painful spinal lesions in neurologically intact patients.

Combined local and systemic bleomycin administration in electrochemotherapy to reduce the number of treatment sessions

2016-01-01

Electrochemotherapy (ECT), a medical treatment widely used in human patients for tumor treatment, increases bleomycin toxicity by 1000 fold in the treated area with an objective response rate of around 80%. Despite its high response rate, there are still 20% of cases in which the patients are not responding. This could be ascribed to the fact that bleomycin, when administered systemically, is not reaching the whole tumor mass properly because of the characteristics of tumor vascularization, in which case local administration could cover areas that are unreachable by systemic administration. We propose combined bleomycin administration, both systemic and local, using companion animals as models. We selected 22 canine patients which failed to achieve a complete response after an ECT treatment session. Eleven underwent another standard ECT session (control group), while 11 received a combined local and systemic administration of bleomycin in the second treatment session. According to the WHO criteria, the response rates in the combined administration group were: complete response (CR) 54% (6), partial response (PR) 36% (4), stable disease (SD) 10% (1). In the control group, these were: CR 0% (0), PR 19% (2), SD 63% (7), progressive disease (PD) 18% (2). In the combined group 91% objective responses (CR+PR) were obtained. In the control group 19% objective responses were obtained. The difference in the response rate between the treatment groups was significant (p < 0.01). Combined local and systemic bleomycin administration was effective in previously to ECT non responding canine patients. The results indicate that this approach could be useful and effective in specific population of patients and reduce the number of treatment sessions needed to obtain an objective response

There is still no well-established consensus about the clinical management of hydatidosis. Currently, surgery continues to be the first therapeutic option, although treatment with anti-parasitic drugs is indicated as an adjuvant to surgery to decrease the number of relapses and hydatid cyst size. When surgery is not possible, medical treatment is indicated. Traditionally, albendazole was used in monotherapy as the standard treatment. However, combined therapy with albendazole plus praziquantel appears to improve anti-parasitic effectiveness. To date, no safety studies focusing on such combined therapy have been published for the treatment of hydatidosis. In this work, we analyze the adverse effects seen in 57 patients diagnosed with hydatidosis who were treated with praziquantel plus albendazole combined therapy between 2006 and 2010. PMID:24615131

The early diagnosis and treatment of primary open-angle glaucoma is challenging, and visual impairment in Chinese glaucoma patients is a serious concern. Most of these patients need more than one topical antiglaucoma agent to control their intraocular pressures (IOPs. In the People’s Republic of China, the daily cost of different glaucoma medication varies greatly, and the treatment habits differ throughout the country. Prostaglandin analogs (PGAs are recommended as first-line monotherapy, because of their efficacy and low risk of systemic side effects. Fixed-combination drops, particularly PGA-based fixed combinations, have recently been developed and used in patients with progression or who have failed to achieve their target IOPs. Here, we reviewed the current literature on the use of bimatoprost-timolol fixed combination (BTFC in the People’s Republic of China. BTFC has achieved good efficacy and tolerability in Chinese clinical trials. In addition, BTFC is more cost effective compared with other fixed combinations available in the People’s Republic of China. Fixed-combination drops may offer benefits, such as keeping the ocular surface healthy, convenience of administration, and improvement in long-term adherence and quality of life. Therefore, BTFC has great potential for the treatment of Chinese glaucoma patients. However, the long-term efficacy of BTFC, comparisons

Vaginal intraepithelial neoplasia (VAIN) represents a variety of changes that initiate as an intraepithelial squamous lesion with the possibility of resulting in cancer. To compare the results of the treatment for the different categories of VAIN with electrocoagulation, 5-fluorouracil and combined treatment. Observational an analytical study. We stablished groups according to the category of VAIN evaluating and comparing remission, persistence, recurrence, or progression of the disease ac- cording to the received treatment, with a 1-year follow up. The results were compared by chi2 and Kruskal Wallis. The statistics analysis was done with the SPSS program version 20. One hundred thirty seven patients between 20 and 81 years of age (mean age: 52.49 years) were included. Seventy-four percent of the patients had a history of premalignant or malignant cervical lesions. Seventy-four patients had VAIN I, 34 patients had VAIN II, 22 patients had VAIN III and there were seven cases of vaginal carcinoma in situ. Fifty-eight patients were treated with electrocoagulation, 55 patients were treated with 5-FU, 16 patients had combined treatment, and eight patients received expectant management. Sixty three percent of patients had total remission of the lesion, 34% had persistence and 3% showed progression, and there were no cases of recurrence. Results were better in patients with VAIN I treated with 5-FU (bigger percentage of remission P .026), for the remaining categories of VAIN, no treatment showed superior results. The superior response occurs in patients with VAIN I treated with 5-FU. None of the treatments achieves a 100% remission. The VAIN frequency is high, patients with a history of malignant or premalignant cervical pathology should undergo a closer surveillance through cytocolposcopic control with respect to the remaining population.

2009-01-01

Treatment of metastatic breast cancer (MBC) with > or =2 chemotherapeutic agents concurrently has been shown to increase response rates, often at the cost of a substantial increase in toxicity, and with minimal impact on the overall survival. However, some combinations of the newer cytotoxic agents, as well as combinations of chemotherapeutic agents and targeted biologic anticancer agents, can produce synergistic efficacy with a manageable toxicity profile. The aims of this work were to provide an overview of the currently approved combination regimens available for the treatment of MBC and to consider the clinical data supporting other drug combinations that may supplement the current therapeutic choices in the near future. Literature searches were performed using MEDLINE/PubMed, with a focus on combination therapies for the treatment of MBC that are approved by the US Food and Drug Administration (FDA) or in Phase III clinical trials. The National Institutes of Health's Clinical Trial Registry was searched for relevant ongoing clinical trials in specific areas. Bibliographies were also searched for additional relevant material. Preference was given to recently published, larger, well-designed clinical trials that influence current prescribing practices. Phase I and II studies, and/or studies older than 10 years (ie, published earlier than 1999), were afforded less emphasis or were disregarded. Combinations of taxanes with capecitabine or gemcitabine, and ixabepilone plus capecitabine, are approved by the FDA as combination regimens for the treatment of MBC. The use of targeted therapies such as trastuzumab, bevacizumab, or lapatinib in combination with taxanes (for the former two) or capecitabine (for lapatinib) is also approved. Several investigational drug combinations are also currently undergoing evaluation in clinical trials, including combinations of bevacizumab and gemcitabine with capecitabine or alternative taxanes.

The objective of the present study was to evaluate the effectiveness of the application of homeovox for the combined treatment of small vocal cord nodules and acute laryngitis in the professional voice users. A total of 40 subjects presenting with dysphonia were examined after they were divided into two study groups and two groups of comparison depending on the nosological form of the pathological condition. The subjects comprising the study groups were given traditional therapy in the combination with the intake of homeovox whereas the patients included in the two groups of comparison received the traditional treatment alone. The outcome of the treatment was evaluated on days 1, 5, and 10 after the initiation of therapy based on the analysis of the changes in the videoendostroboscopic picture of the larynx and the acoustic characteristics obtained by the computer-assisted analysis of the voice. The analysis of the results of the combined treatment has demonstrated the statistically significant differences in some acoustic parameters of the voice between the subjects with small vocal cord nodules and acute laryngitis belonging to the study groups and the groups of comparison. It is concluded that the introduction of homeovox in the combined treatment of the patients presenting with the small nodules in the vocal cords and acute catarrhal laryngitis accelerates the recovery of the acoustic characteristics of the voice within various periods after the onset of the treatment in comparison with the patients treated with the use of traditional therapy alone.

One hundred and thirty six patients with chancroid were treated with four different treatment regimens; (A) Sulphaphenazole 1 g 12 hourly by mouth x 10 days (B) Inj streptomycin 1 g intramuscularly daily with sulphaphenazole 1 g 12 hourly orally x 10 days; (C) trimethoprim 200 mg 12 hourly by mouth x 7-10 days, and (D) erythromycin 500 mg 6 hourly orally x 7-10 days. Cure rates of 9% with sulphaphenazole alone, 48% with streptomycin and sulphaphenazole combination, 93% with trimethoprim and 100% with erythromycin were obtained. Sulphaphenazole alone or in combination with streptomycin were thus inferior in the treatment of chancroid. There is need for modification of treatment regimens recommended for chancroid in the textbooks of dermatology and venereology. Trimethoprim can be recommended as first line of treatment for chancroid in developing countries like India where resistance to trimethoprim is uncommon and erythromycin is suggested as a second line of therapy because by that time syphilis can be easily ruled out.

These experiments were designed to determine whether treatment with two subthreshold doses of radiation or lithium chloride, either alone or in combination, could lead to taste aversion learning. The first experiment determined the thresholds for a radiation-induced taste aversion at 15-20 rad and for lithium chloride at 0.30-0.45 mEq/kg. In the second experiment it was shown that exposing rats to two doses of 15 rad separated by up to 3 hr produced a taste aversion. Treatment with two injections of lithium chloride (0.30 mEq/kg) did not produce a significant reduction in preference. Combined treatment with radiation and lithium chloride did produce a taste aversion when the two treatments were administered within 1 hr of each other. The results are discussed in terms of the implications of these findings for understanding the nature of the unconditioned stimuli leading to the acquisition of a conditioned taste aversion

Since the liquid separated from sludge in the dehydration or concentration process of sewer sludge contains considerable amount of organic compositions that are hard to be decomposed by microorganisms, it has become difficult to be treated by conventional activated sludge process. In the case of discharging the separated liquid into closed water areas, the higher quality treatment is required. The method of using electron beam irradiation and ozone oxidation in combination for cleaning the liquid separated from sludge was examined, therefore, the results are reported. The water quality of the sample from the sludge treatment plant in A City is shown. The method of bio-pretreatment, the treatment method by using electron beam and ozone in combination, and the method of analyzing the water quality are described. The effect of the treatment by activated sludge process, as the effect of the treatment by the combined use of electron beam and ozone, the change of COD and TOC, the change of chromaticity, the change of gel chromatogram, and the reaction mechanism are reported. In this paper, only the basic concept on the model plant for applying the method of the combined use of electron beam and ozone to the treatment of the liquid separated from sludge is discussed.

To develop the combined method of treatment of hemorrhoids with arterial ligation under Doppler control and laser destruction of internal and external hemorrhoids. The study included 100 patients with chronic hemorrhoids stage II and III. Combined method of HAL-laser was used in study group, HAL RAR-technique in control group 1 and closed hemorrhoidectomy with linear stapler in control group 2. Сomparative evaluation of results in both groups was performed. Combined method overcomes the drawbacks of traditional surgical treatment and limitations in external components elimination which are inherent for HAL-RAR. Moreover, it has a higher efficiency in treating of hemorrhoids stage II-III compared with HAL-RAR and is equally safe and well tolerable for patients. This method does not increase the risk of recurrence, reduces incidence of complications and time of disability.

The combination of radiotherapy with chemotherapy is one of the most promising strategies for cancer treatment. Here, a novel combination strategy utilizing carbon ion irradiation as a high-linear energy transfer (LET) radiotherapy and a thermo-triggered nanodevice is proposed, and drug accumulation in the tumor and treatment effects are evaluated using magnetic resonance imaging relaxometry and immunohistology (Ki-67, n = 15). The thermo-triggered liposomal anticancer nanodevice was administered into colon-26 tumor-grafted mice, and drug accumulation and efficacy was compared for 6 groups (n = 32) that received or did not receive the radiotherapy and thermo trigger. In vivo quantitative R 1 maps visually demonstrated that the multimodal thermosensitive polymer-modified liposomes (MTPLs) can accumulate in the tumor tissue regardless of whether the region was irradiated by carbon ions or not. The tumor volume after combination treatment with carbon ion irradiation and MTPLs with thermo-triggering was significantly smaller than all the control groups at 8 days after treatment. The proposed strategy of combining high-LET irradiation and the nanodevice provides an effective approach for minimally invasive cancer treatment. Copyright © 2017 The Author(s).

Applying radiobiological principles to combined modality treatment of head and neck cancer--the time factor

International Nuclear Information System (INIS)

Peters, Lester J.; Withers, H. Rodney

1997-01-01

Purpose: Combined modality treatment is indicated for most advanced stage head and neck cancers. It is postulated that the efficacy of combined modality regimens could be enhanced by applying principles derived from radiotherapy fractionation studies to optimize the time factor in treatment scheduling. Methods and Materials: The premise that tumor clonogens surviving a therapeutic intervention undergo accelerated repopulation in a time-dependent fashion as their numbers are depleted is used as a model to interpret the results of various chemoradiotherapy and postsurgical radiotherapy protocols and to suggest ways in which future combined modality regimens can be more rationally designed. Results: Meta-analyses of chemoradiotherapy trials show the general superiority of concomitant vs. neoadjuvant sequential protocols. There is also emerging evidence that both the duration of postoperative radiotherapy and the delay in its instigation affect treatment outcome. These results are compatible with the hypothesis that the overall duration of the 'package deal' of combined modality treatment is an important determinant of outcome. However, a large decrease in duration of the 'package deal' does not necessarily translate into a therapeutic gain because the total dose has to be lowered to prevent intolerable acute reactions. In these circumstances tumor control will improve only if the reduced treatment time circumvents more tumor cell regeneration than the cytoreduction that could be achieved by the extra dose tolerable in a longer time period. More modest reductions in treatment time can be accomplished without dose reduction and so avoid this risk. The design of new protocols should take account of the fact that regeneration of tumor clonogens can be predicted to be nonuniform with time. Thus, the greatest therapeutic gain should be achieved by targeting periods of maximal regenerative capacity for shortening or, alternatively, for intensification of treatment. These

To study prospects of application of local hyperthermia, artificial hyperglycemia and radiotherapy in a preoperative period, 31 patients with rectum cancer were studied. The treatment included 3-hour artificial hyperglycemia first, then local SHF hyperthermia and telegamma irradiation using large-fractioned doses (ROD is 5 Gy, COD is 20 Gy). No serious side-effects were observed during the preoperative treatment period. The immediate and early results of combined treatment promise to improve the effectiveness of treatment of patients with rectum cancer. 3 refs

The aim of this paper is to compare the efficacy of tamsulosin, oxybutynin or their combination for the treatment of symptoms related to double J stent (DJS). Randomized clinical non-blinded trial with three arms (tamsulosin, oxybutynin or combination) to assess the improvement of ureteral related symptoms with DJS with the questionnaire of Ureteral Stent Symptom Questionnaire (USSQ) and the adverse effects of treatment. Evaluations were made at 7 and 21 days after the placement of DJS. The maneuvers were compared using Chi squared test, Kruskall-Wallis, ANOVA and Wilcoxon considering a statistically significant p ≤ 0.05. 170 patients with CJJ were evaluated. A perprotocol analysis was performed in 142 patients, 53 received tamsulosin (37.4%), 42 oxybutynin (29.6%) and 47 the combination of both (33%). At 7 and 21 days the improvement was similar in all three arms. Men with tamsulosin and women with oxybutynin had less general symptoms. Tamsulosin, oxybutynin or its combination similarly improve ureteral stent related symptoms and this improvement becomes more noticeable over time. Men are less symptomatic with tamsulosin and women with oxybutynin.

Full Text Available Traditional thermophillic composting is commonly for treatment of sludge. A related technique as vermicomposting process, using earthworms to breakdown sludge, is also becoming popular. These two techniques have their inherent advantages and disadvantages. The combined approach suggested in this study to enhance the overall process and improve the products qualities. Two systems,vermicomposting and combined compost vermicomposting processes, have been investigated in this study. The sludge used in this study was obtained from the drying beds of South Isfahan wastewater treatment plant.The sludge mixed with sawdust to provide C/N ratio of 25/1.Eisenia fetida was the species of earthworms used in the vermicomposting processes.The results obtained indicates reduction in the amount of volatile solids,total carbon and C/N ratio with the vermicompost age,which indicates the reduction in the biodegradable organic content and mineralization of sludge. Also increase in phosphorus concentration by the end process because of mineralization of organic matter. The results indicate that, a system that combines the two mentioned processes not only shortens stabilization time, but also improves the products quality. Combining the two systems resulted in a product that was more stable and homogenous; the product could meet the pathogen reduction requirements.

Radioprotectors effect on the efficiency of combined treatment of radiation injuries (review of the literature)

Therapeutic efficiency of radioprotector action (cystamine, in particular) under isolated and combined (in combination with burns, mechanical injuries of skull, brain, limbs internal organs etc.) radiation affection is discussed on the basis of experiment data, obtained by different authors. The conclusion is drawn, that under combined radiation affections with leading radial component, radioprotectors provide for approximately the same protection effect as under isolated radioactive irradiation by a corresponding dose. In combination with radial and nonradial injury means they can sufficiently reduce lethality and create better conditions for favourable course of burn deseases and mechanical injuries. It is pointed out, that preliminary protection gains decisive value in cases, when under combined radiation affection the radial component prevails. In this case radiosensitive tissue protection becomes necessary condition for the victim's life preservation, complication frequency reduction and improvement of treatment results. Advisability of inclusion of medical protection means into the step-by-step treatment system, wile foreseeing both isolated and combined radiation affections, is shown

Bacterial spores are inactivated by moderate hydrostatic pressures. The radiation dose required to sterilize radiation sensitive pharmaceuticals can be considerably reduced using a combination hydrostatic pressure-radiation treatment. This paper describes a combination pressure-radiation sterilization process using Bacillus pumilus spores suspended in water, 0.9% saline, and 5% dextrose solutions. The optimum temperatures for spore inactivation at 35 MPa and the degree of inactivation at 35, 70 and 105 MPa applied for times up to 100 min have been determined. Inactivation was greatest in saline and least in dextrose. Spores in dextrose were only slightly less radiation resistant than in saline or water. It was calculated that the radiation dose required for sterilization could be halved with appropriate compression treatment. Examples of combinations of pressure-radiation suitable for sterilization are given. One combination is compression at 105 MPa for 18 min for a dose of 1.25 Mrad. (author)

Combined treatment of xenon and hypothermia in newborn rats--additive or synergistic effect?

Full Text Available Breathing the inert gas Xenon (Xe enhances hypothermic (HT neuroprotection after hypoxia-ischemia (HI in small and large newborn animal models. The underlying mechanism of the enhancement is not yet fully understood, but the combined effect of Xe and HT could either be synergistic (larger than the two effects added or simply additive. A previously published study, using unilateral carotid ligation followed by hypoxia in seven day old (P7 rats, showed that the combination of mild HT (35°C and low Xe concentration (20%, both not being neuroprotective alone, had a synergistic effect and was neuroprotective when both were started with a 4 h delay after a moderate HI insult. To examine whether another laboratory could confirm this finding, we repeated key aspects of the study.After the HI-insult 120 pups were exposed to different post-insult treatments: three temperatures (normothermia (NT NT37°C, HT35°C, HT32°C or Xe concentrations (0%, 20% or 50% starting either immediately or with a 4 h delay. To assess the synergistic potency of Xe-HT, a second set (n = 101 of P7 pups were exposed to either HT35°C+Xe0%, NT+Xe20% or a combination of HT35°C+Xe20% starting with a 4 h delay after the insult. Brain damage was analyzed using relative hemispheric (ligated side/unligated side brain tissue area loss after seven day survival.Immediate HT32°C (p = 0.042, but not HT35°C significantly reduced brain injury compared to NT37°C. As previously shown, adding immediate Xe50% to HT32°C increased protection. Neither 4 h-delayed Xe20%, nor Xe50% at 37°C significantly reduced brain injury (p>0.050. In addition, neither 4 h-delayed HT35°C alone, nor HT35°C+Xe20% reduced brain injury. We found no synergistic effect of the combined treatments in this experimental model.Combining two treatments that individually were ineffective (delayed HT35°C and delayed Xe20% did not exert neuroprotection when combined, and therefore did not show a synergistic

Full Text Available Objective: To explore the clinical efficacy of valsartan combined with hydrochlorothiazide in the treatment of elderly hypertension. Methods: A total of 150 elderly patients with primary hypertension who were admitted in our hospital from January, 2015 to January, 2016 were included in the study and randomized into the observation group and the control group. The patients in the control group were given valsartan, 80 mg/time, 1 time/d. On this basis, the patients in the observation group were given additional hydrochlorothiazide 12.5 mg/time, 1 time/d. The patients in the two groups were administered with drugs in the morning. Six-month treatment was regarded as one course. The change of 24 h ambulatory blood pressure before and after treatment was detected, and the efficacy was evaluated. The heart color ultrasound was used to detect LVM and LVMI before and after treatment in the two groups. Results: The total effective rate in the observation group (90.7% was significantly superior to that in the control group (70.7% (P<0.05. The mean SBP and DBP 24h after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05, and those in the observation group were significantly superior to those in the control group (P<0.05. LVM and LVMI after treatment in the two groups were significantly reduced when compared with before treatment (P<0.05, and those in the observation group were significantly superior to those in the control group (P<0.05. Conclusions: The combination of valsartan and hydrochlorothiazide in the treatment of elderly hypertension can effectively enhance the clinical efficacy, and effectively control the blood pressure. It is superior to that by a single drug; therefore, and deserves to be widely recommended in the clinic.

Prevalence studies from India suggest that epilepsy prevalence is similar to developed nations. Neurocysticercosis (NCC) predominates as an etiology. A large treatment gap is still a public health problem. Benign epilepsies and West syndrome appear to be underrepresented in studies on classification of seizures/syndromes. Febrile seizures prevalence in India is similar to other countries and appear to be as benign. Risk factors of intractable epilepsy (IE) in Indian studies include early age of onset, neurodevelopmental abnormalities and certain seizure types. Perinatal injuries underlie many IE. Many IE are not truly intractable and respond to simple therapeutic measures. The ketogenic diet and surgery are other methods now being used in Indian centers. Neurocysticercosis and neonatal hypoglycemic brain injury, two widely prevalent etiologies are reviewed in detail.

2004-09-01

Full Text Available Abstract Background The combination of spinal manipulation and various physiotherapeutic procedures used to correct the curvatures associated with scoliosis have been largely unsuccessful. Typically, the goals of these procedures are often to relax, strengthen, or stretch musculotendinous and/or ligamentous structures. In this study, we investigate the possible benefits of combining spinal manipulation, positional traction, and neuromuscular reeducation in the treatment of idiopathic scoliosis. Methods A total of 22 patient files were selected to participate in the protocol. Of these, 19 met the study criterion required for analysis of treatment benefits. Anteroposterior radiographs were taken of each subject prior to treatment intervention and 4–6 weeks following the intervention. A Cobb angle was drawn and analyzed on each radiograph, so pre and post comparisons could be made. Results After 4–6 weeks of treatment, the treatment group averaged a 17° reduction in their Cobb angle measurements. None of the patients' Cobb angles increased. A total of 3 subjects were dismissed from the study for noncompliance relating to home care instructions, leaving 19 subjects to be evaluated post-intervention. Conclusions The combined use of spinal manipulation and postural therapy appeared to significantly reduce the severity of the Cobb angle in all 19 subjects. These results warrant further testing of this protocol.

The enzyme-linked immunoelectrotransfer blot (EITB) assay is the reference serological test for neurocysticercosis (NCC). A positive result on EITB does not always correlate with the presence of active infections in the central nervous system (CNS), and patients with a single viable brain cyst may be EITB negative. Nonetheless, EITB antibody banding patterns appears to be related with the expression of 3 protein families of Taenia solium, and in turn with the characteristics of NCC in the CNS (type, stage, and burden of viable cysts). We evaluated EITB antibody banding patterns and brain imaging findings of 548 NCC cases. Similar banding patterns were grouped into homogeneous classes using latent class analysis. The association between classes and brain imaging findings was assessed. Four classes were identified. Class 1 (patients negative or only positive to the GP50 band, related to the protein family of the same name) was associated with nonviable or single viable parenchymal cysticerci; class 2 (patients positive to bands GP42-39 and GP24, related to the T24-42 protein family, with or without anti-GP50 antibodies) was associated with intraparenchymal viable and nonviable infections; classes 3 and 4 (positive to GP50, GP42-39, and GP24 but also responding to low molecular weight bands GP21, GP18, GP14, and GP13, related to the 8 kDa protein family) were associated with extraparenchymal and intraparenchymal multiple viable cysticerci. EITB antibody banding patterns correlate with brain imaging findings and complement imaging information for the diagnosis of NCC and for staging NCC patients. © The Author 2017.

Human cystic echinococcosis is a zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus sensu lato (s. l.). Although benzimidazole compounds such as albendazole (ABZ) and mebendazole have been the cornerstone of chemotherapy for the disease, there is often no complete recovery after treatment. Hence, new strategies are required to improve treatment of human cystic echinococcosis. The goals of the current study were as follows: (i) to evaluate the in vitro efficacy of the 5-fluorouracil (5-FU) and ABZ combination against E. granulosus s. l. protoscoleces and cysts, (ii) to compare the clinical efficacy of 5-FU alone or in combination with ABZ in infected mice. The combination of 5-FU+ABZ had a stronger in vitro effect against larval stage than that did both drugs alone. Even at the lowest concentration of 5-FU+ABZ combination (1μg/ml), the reduction of the viability of protoscoleces and cysts was greater than that observed with drugs alone at 10μg/ml. The results were confirmed at the ultrastructural level by scanning electron microscopy. These data helped to justify the in vivo investigations assessing the therapeutic potential of the combination of 5-FU and ABZ suspension in CF-1 mice infected with E. granulosus sensu stricto (s. s.) metacestodes. Treatment with 5-FU (10mg/kg) or 5-FU (10mg/kg) + ABZ suspension (5mg/kg) reduced the weight of cysts recovered from mice compared with control groups. Interestingly, the effect of 5-FU given weekly for 5 consecutive weeks was comparable to that observed with ABZ suspension under a daily schedule during 30days. Co-administration of 5-FU with ABZ did not enhance the in vivo efficacy of drugs alone calculated in relation to cysts weights. However, the combination provoked greater ultrastructural alterations compared to the monotherapy. In conclusion, we demonstrated the efficacy of 5-FU either alone or co-administrated with ABZ against murine experimental cystic echinococcosis. Since 5-FU treatments

Regorafenib, an oral multikinase inhibitor, has demonstrated survival benefit in metastatic colorectal cancer (mCRC) patients that have progressed after all standard therapies. However, novel strategies to improve tolerability and enhance anti-cancer efficacy are needed. We have evaluated in vitro the effects of regorafenib in combination with silybin, a biologically active component extracted from the seeds of Silybum marianum, in a panel of human colon cancer cells. Furthermore, we have prospectively treated a cohort of 22 refractory mCRC patients with regorafenib plus silybin. Treatment with regorafenib determined a dose-dependent growth inhibition whereas treatment with silybin had no anti-proliferative effects among all cancer cells tested. The combined treatment with regorafenib and silybin induced synergistic anti-proliferative and apoptotic effects by blocking PI3K/AKT/mTOR intracellular pathway. Moreover, combined treatment with regorafenib and silybin increased the production of reactive oxygen species levels within cells. In an exploratory proof of concept clinical study in a cohort of 22 mCRC patients after failure of all standard therapies, the clinical activity of regorafenib in combination with silybin was assessed. A median progression-free survival of 10.0 months and a median overall survival of 17.6 months were observed in these patients. These results suggest that the combined treatment potentially increases the clinical efficacy of regorafenib. Moreover, due to its anti-oxidative properties, silybin could protect patients from drug-induced liver damages, allowing to continue an effective anti-cancer therapy. The present study suggests that silybin in combination with regorafenib is a promising strategy for treatment of metastatic colorectal patients.

In this study, we aimed to investigate the efficacy of combined orthodontic-periodontic treatment in the treatment of patients with periodontitis and its effects on the levels of inflammatory cytokines. A total of 117 patients with periodontitis were randomly assigned to the basic group (receiving basic periodontic treatment, n = 58) and the combined group (receiving combined orthodontic-periodontic treatment, n = 59). In addition, 52 healthy people without periodontal disease were selected as the normal group. Probing depth, tooth mobility, plaque index, clinical attachment level, and sulcus bleeding index were recorded. ELISA was applied to detect gingival crevicular fluid (GCF) and serum levels of inflammatory cytokines. A 2-year clinical follow-up was conducted. Before treatment, the periodontal parameters (probing depth, tooth mobility, plaque index, clinical attachement level, and sulcus bleeding index) and GCF and serum levels of inflammatory cytokines (high-sensitivity C-reactive protein, interleukin-1β, interleukin-5, interleukin-6, interleukin-8, tumor necrosis factor-α, and prostaglandin E2) in the combined and basic groups were higher than those in the normal group. After 6 and 18 months of treatment, the periodontal parameters and GCF and serum levels of inflammatory cytokines decreased in the combined and basic groups. The periodontal parameters and the GCF and serum levels of inflammatory cytokines in the combined group were significantly lower than those in the basic group after 18 months of treatment. The combined group had a lower recurrence rate compared with the basic group. Combined orthodontic-periodontic treatment had good clinical efficacy in the treatment of periodontitis and could effectively decrease the levels of inflammatory cytokines.

Bioactive coatings have been investigated to enhance the integration of orthopaedic and dental-craniofacial implants in the surrounding bone tissue. Chitosan has been shown to possess many properties desirable in implant coatings, such as cell attachment and growth, and encouraging ordered bone tissue formation. Previous studies have produced methods to deposit chitosan onto a titanium surface using both two-step and three-step reaction schemes. In the current study, two different titanium surface treatments were evaluated for determining the strength of chitosan coatings bonded to titanium via two reaction processes. The chitosan coatings produced from the four treatment combinations were examined using X-ray Photoelectron Spectroscopy, which demonstrated that the final coatings were similar in composition to the previously reported coatings. Coatings examined by nano-indentation, exhibited hardness (0.19 {+-} 0.08 GPa) and elastic modulus (4.90 {+-} 1.82 GPa) values similar to the hardness and elastic modulus values previously reported. Scanning Electron Microscopy examination of the nano-indentation marks revealed cracks only at sites of applied stress, demonstrating that the chitosan coatings were able to absorb the applied stress. Bulk adhesion of the chitosan coatings demonstrated significant increases in bond strength (19.50 {+-} 1.63 MPa) over previously reported data (1.5-1.8 MPa), but no significant differences were seen between the four treatment combinations. Contact angle testing demonstrated that the chitosan coatings were more hydrophobic (98.0 {+-} 3.6 deg.) than published values (76.4 {+-} 5.1 deg.). Overall, mechanical testing demonstrated that, while the bulk properties of the chitosan coating were unaffected by the four treatment combinations, the bulk adhesion of the chitosan coating was greatly increased and high quality coatings were produced.

Neutrino decay in vacuum has often been considered as an alternative to neutrino oscillations. Because nonzero neutrino masses imply the possibility of both neutrino decay and neutrino oscillations, we present a model-independent formal treatment of these combined scenarios. For that, we show for the example of Majoron decay that in many cases decay products are observable and may even oscillate. Furthermore, we construct a minimal scenario in which we study the physical implications of neutrino oscillations with intermediate decays

Backgrounds Since most patients with castration-resistant prostate cancer (CRPC) develop resistance to its standard therapy docetaxel, many studies have attempted to identify novel combination treatment to meet the large clinical unmet need. In this study, we examined whether histone deacetylase inhibitors (HDACIs) enhanced the effect of docetaxel on AR signaling in CRPC cells harboring AR and its splice variants. Methods HDACIs (vorinostat and CG200745) were tested for their ability to enhance the effects of docetaxel on cell viability and inhibition of AR signaling in CRPC 22Rv1 and VCaP cells by using CellTiter-Glo™ Luminescent cell viability assay, synergy index analysis and Western blotting. The nuclear localization of AR was examined via immunocytochemical staining in 22Rv1 cells and primary tumor cells from a patient with CRPC. Results Combination treatment with HDACIs (vorinostat or CG200745) and docetaxel synergistically inhibited the growth of 22Rv1 and VCaP cells. Consistently, the combination treatment decreased the levels of full-length AR (AR-FL), AR splice variants (AR-Vs), prostate-specific antigen (PSA), and anti-apoptotic Bcl-2 proteins more efficiently compared with docetaxel or vorinostat alone. Moreover, the combination treatment accelerated the acetylation and bundling of tubulin, which significantly inhibited the nuclear accumulation of AR in 22Rv1 cells. The cytoplasmic colocalization of AR-FL and AR-V7 with microtubule bundles increased after combination treatment in primary tumor cells from a patient with CRPC. Conclusions The results suggested that docetaxel, in combination with HDACIs, suppressed the expression and nuclear translocation of AR-FL and AR-Vs and showed synergistic anti-proliferative effect in CRPC cells. This combination therapy may be useful for the treatment of patients with CRPC.

Binge eating disorder (BED) is characterized by recurrent binge eating and marked distress about binge eating without the extreme compensatory behaviors for weight control that characterize other eating disorders. BED is prevalent, associated strongly with obesity, and is associated with heightened levels of psychological, psychiatric, and medical concerns. This article provides an overview of randomized controlled treatments for combined psychological and pharmacological treatment of BED to inform current clinical practice and future treatment research. In contrast to the prevalence and significance of BED, to date, limited research has been performed on combining psychological and pharmacological treatments for BED to enhance outcomes. Our review here found that combining certain medications with cognitive behavioral therapy (CBT) or behavioral weight loss (BWL) interventions produces superior outcomes to pharmacotherapy only but does not substantially improve outcomes achieved with CBT/BWL only. One medication (orlistat) has improved weight losses with CBT/BWL albeit minimally, and only one medication (topiramate) has enhanced reductions achieved with CBT in both binge eating and weight. Implications for future research are discussed.

Type 1 diabetes mellitus (T1DM) is an autoimmune disease leading to near complete pancreatic β-cell destruction. New evidence suggests that β-cell regeneration is possible, but ongoing autoimmune damage prevents restoration of β-cell mass. We tested the hypothesis that simultaneously blocking autoimmune cytokine damage and supplying a growth-promoting stimulus for β-cells would provide a novel approach to reverse T1DM. Therefore, in this study we combined lisofylline to suppress autoimmunity and exendin-4 to enhance β-cell proliferation for treating autoimmune-mediated diabetes in the non-obese diabetic (NOD) mouse model. We found that this combined therapy effectively reversed new-onset diabetes within a week of therapy, and even maintained euglycemia up to 145 days after treatment withdrawal. The therapeutic effect of this regimen was associated with improved β-cell metabolism and insulin secretion, while reducing β-cell apoptosis. It is possible that such combined therapy could become a new strategy to defeat T1DM in humans

Full Text Available BACKGROUND: The World Health Organization currently recommends combined streptomycin and rifampicin antibiotic treatment as first-line therapy for Mycobacterium ulcerans infections. Alternatives are needed when these are not tolerated or accepted by patients, contraindicated, or neither accessible nor affordable. Despite in vitro effectiveness, clinical evidence for fluoroquinolone antibiotic use against Mycobacterium ulcerans is lacking. We describe outcomes and tolerability of fluoroquinolone-containing antibiotic regimens for Mycobacterium ulcerans in south-eastern Australia. METHODOLOGY/PRINCIPAL FINDINGS: Analysis was performed of prospectively collected data including all primary Mycobacterium ulcerans infections treated at Barwon Health between 1998 and 2010. Medical treatment involved antibiotic use for more than 7 days; surgical treatment involved surgical excision of a lesion. Treatment success was defined as complete lesion healing without recurrence at 12 months follow-up. A complication was defined as an adverse event attributed to an antibiotic that required its cessation. A total of 133 patients with 137 lesions were studied. Median age was 62 years (range 3-94 years. 47 (34% had surgical treatment alone, and 90 (66% had combined surgical and medical treatment. Rifampicin and ciprofloxacin comprised 61% and rifampicin and clarithromycin 23% of first-line antibiotic regimens. 13/47 (30% treated with surgery alone failed treatment compared to 0/90 (0% of those treated with combination medical and surgical treatment (p<0.0001. There was no difference in treatment success rate for antibiotic combinations containing a fluoroquinolone (61/61 cases; 100% compared with those not containing a fluoroquinolone (29/29 cases; 100%. Complication rates were similar between ciprofloxacin and rifampicin (31% and rifampicin and clarithromycin (33% regimens (OR 0.89, 95% CI 0.27-2.99. Paradoxical reactions during treatment were observed in 8 (9% of

In silicon, the effect of Combined Lifetime Treatment (CLT) involving platinum diffusion and subsequent electron irradiation is different from the separate treatments of platinum diffusion and electron irradiation, even the treatment of electron irradiation followed by platinum diffusion. In this paper, we investigated the experimental behavior of different kinds of lifetime treated samples. We found that the reverse leakage current (I rr ) increases with the increasing platinum diffusion temperature or electron irradiation dose in the separate treatments. Conversely, I rr of the CLT samples decreased with rising platinum diffusion temperature at the same dose of subsequent electron irradiation. By deep-level transient spectroscopy (DLTS), a new energy level E7 (Ec −0.376 eV) was found in our CLT samples. The new level E7 suppresses the dominance of the deeper level E8 (Ec −0.476 eV), which is caused by electron irradiation directly and results in I rr ’s increase. The formation of the level E7 comes from the complex defect-combined effect between platinum atoms and silicon vacancies, and it affects device’s characteristics finally. These research will be helpful to the development of platinum-diffused devices used in intense electron irradiation environments.

Development of shelf stable, processed, low acid food products using heat-irradiation combination treatments

International Nuclear Information System (INIS)

Minnaar, A.

1998-01-01

The amount of ionizing irradiation needed to sterilize low acid vegetable and starch products (with and without sauces) commercially impairs their sensorial and nutritive qualities, and use of thermal processes for the same purpose may also have an adverse effect on the product quality. A systematic approach to the establishment of optimized combination parameters was developed for heat-irradiation processing to produce high quality, shelf stable, low acid food products. The effects of selected heat, heat-irradiation combination and irradiation treatments on the quality of shelf stable mushrooms in brine and rice, stored at ambient temperature, were studied. From a quality viewpoint, use of heat-irradiation combination treatments favouring low irradiation dose levels offered a feasible alternative to thermally processed or radappertized mushrooms in brine. However, shelf stable rice produced by heat-irradiation combination treatments offered a feasible alternative only to radappertized rice from the standpoint of quality. The technical requirements for the heat and irradiation processing of a long grain rice cultivar from the United States of America oppose each other directly, thereby reducing the feasibility of using heat-irradiation combination processing to produce shelf stable rice. The stability of starch thickened white sauces was found to be affected severely during high dose irradiation and subsequent storage at ambient temperature. However, use of pea protein isolate as a thickener in white sauces was found to have the potential to maintain the viscosity of sauces for irradiated meat and sauce products throughout processing and storage.

2013-03-01

Full Text Available ABSTRACTBackground: Prostate cancer is the second most common cancer in American men. The development of alternative preventative and/or treatment options utilizing a combination of phytochemicals and chemotherapeutic drugs could be an attractive alternative compared to conventional carcinoma treatments. Genistein isoflavone is the primary dietary phytochemical found in soy and has demonstrated anti-tumor activities in LNCaP prostate cancer cells. Topotecan Hydrochloride (Hycamtin is an FDA-approved chemotherapy for secondary treatment of lung, ovarian and cervical cancers. The purpose of this study was to detail the potential activation of the intrinsic apoptotic pathway in LNCaP prostate cancer cells through genistein-topotecan combination treatments.Methods: LNCaP cells were cultured in complete RPMI medium in a monolayer (70-80% confluency at 37ºC and 5% CO2. Treatment consisted of single and combination groups of genistein and topotecan for 24 hours. The treated cells were assayed for i growth inhibition through trypan blue exclusion assay and microphotography , ii classification of cellular death through acridine/ ethidium bromide fluorescent staining, and iii activation of the intrinsic apoptotic pathway through Jc-1: mitochondrial membrane potential assay, cytochrome c release and Bcl-2 protein expression.Results: The overall data indicated that genistein-topotecan combination was significantly more efficacious in reducing the prostate carcinoma’s viability compared to the single treatment options. In all treatment groups, cell death occurred primarily through the activation of the intrinsic apoptotic pathway.Conclusion: The combination of topotecan and genistein has the potential to lead to treatment options with equal therapeutic efficiency as traditional chemo- and radiation therapies, but lower cell cytotoxicity and fewer side effects in patients.

Combined Immune Therapy for the Treatment of Visceral Leishmaniasis.

Full Text Available Chronic disease caused by infections, cancer or autoimmunity can result in profound immune suppression. Immunoregulatory networks are established to prevent tissue damage caused by inflammation. Although these immune checkpoints preserve tissue function, they allow pathogens and tumors to persist, and even expand. Immune checkpoint blockade has recently been successfully employed to treat cancer. This strategy modulates immunoregulatory mechanisms to allow host immune cells to kill or control tumors. However, the utility of this approach for controlling established infections has not been extensively investigated. Here, we examined the potential of modulating glucocorticoid-induced TNF receptor-related protein (GITR on T cells to improve anti-parasitic immunity in blood and spleen tissue from visceral leishmaniasis (VL patients infected with Leishmania donovani. We found little effect on parasite growth or parasite-specific IFNγ production. However, this treatment reversed the improved anti-parasitic immunity achieved by IL-10 signaling blockade. Further investigations using an experimental VL model caused by infection of C57BL/6 mice with L. donovani revealed that this negative effect was prominent in the liver, dependent on parasite burden and associated with an accumulation of Th1 cells expressing high levels of KLRG-1. Nevertheless, combined anti-IL-10 and anti-GITR mAb treatment could improve anti-parasitic immunity when used with sub-optimal doses of anti-parasitic drug. However, additional studies with VL patient samples indicated that targeting GITR had no overall benefit over IL-10 signaling blockade alone at improving anti-parasitic immune responses, even with drug treatment cover. These findings identify several important factors that influence the effectiveness of immune modulation, including parasite burden, target tissue and the use of anti-parasitic drug. Critically, these results also highlight potential negative effects of

The present work highlights the novel approach of combination of hydrodynamic cavitation and advanced oxidation processes for wastewater treatment. The initial part of the work concentrates on the critical analysis of the literature related to the combined approaches based on hydrodynamic cavitation followed by a case study of triazophos degradation using different approaches. The analysis of different combinations based on hydrodynamic cavitation with the Fenton chemistry, advanced Fenton chemistry, ozonation, photocatalytic oxidation, and use of hydrogen peroxide has been highlighted with recommendations for important design parameters. Subsequently degradation of triazophos pesticide in aqueous solution (20 ppm solution of commercially available triazophos pesticide) has been investigated using hydrodynamic cavitation and ozonation operated individually and in combination for the first time. Effect of different operating parameters like inlet pressure (1-8 bar) and initial pH (2.5-8) have been investigated initially. The effect of addition of Fenton's reagent at different loadings on the extent of degradation has also been investigated. The combined method of hydrodynamic cavitation and ozone has been studied using two approaches of injecting ozone in the solution tank and at the orifice (at the flow rate of 0.576 g/h and 1.95 g/h). About 50% degradation of triazophos was achieved by hydrodynamic cavitation alone under optimized operating parameters. About 80% degradation of triazophos was achieved by combination of hydrodynamic cavitation and Fenton's reagent whereas complete degradation was achieved using combination of hydrodynamic cavitation and ozonation. TOC removal of 96% was also obtained for the combination of ozone and hydrodynamic cavitation making it the best treatment strategy for removal of triazophos. Copyright © 2014 Elsevier B.V.

Patients received treatment according B-NHL 2004mab protocol (n = 83 and B-NHL 2010M (n = 158 with combined immunochemotherapy (ICT in Russian and Belarus pediatric clinics from 2004 to 2015 years. Primary patients with different mature B-NHL (Burkitt lymphoma/leukemia, diffuse large B-cell lymphoma and primary mediastinal B-cell lymphoma (DLBCL and PMBCL aged from 2 to 18 years are included in the studies.Protocol B-NHL 2004mab for treatment of children and adolescents with B-NHL/B-AL, stage III and IV, includes a combination of chemotherapy (PCT and rituximab – an antibody against the B-cells receptor CD20. PCT courses similar to those in the B-NHL BFM90 protocol (group III with the exception of methotrexate dose in induction courses, reduced to 1 g/m2 /24 h in order to reduce toxicity. Rituximab (Mabthera, 375 mg/m2 /h used for the first time in the treatment of children and adolescents with B-NHL. Of the 83 patients included, clinical remission was achieved in 77 (92.8 %.

Clinical trials demonstrated that a fixed-dose combination (FDC) of the beta-blocker nebivolol (5 mg) and the angiotensin II antagonist valsartan (80 mg) produced a significant reduction of both diastolic and systolic blood pressure in patients with hypertension. Both nebivolol and valsartan contributed to this effect, partial additivity of 86.6% and 82.2% being observed for diastolic and systolic blood pressure, respectively. These values are very similar to the additivity ratios of other recently approved FDCs for hypertension. Use of the FDC nebivolol 5 mg/valsartan 80 mg formulation was associated with a low incidence of treatment-related adverse effects and of serious adverse effects. There was no evidence of adverse effects due to beta2-adrenoceptor blockade. The FDC (Byvalson) was approved and launched in 2016 in the U.S. for the treatment of hypertension.

1997-01-01

Background: Treatment of locally advanced and recurrent rectal cancer usually has a high local recurrence rate and poor survival. Promising results have been reported by combined external radiotherapy, extensive surgery and intraoperative radiotherapy (IORT). Methods: One hundred fifteen patients with locally advanced rectal cancers fixed to the pelvic wall or locally recurrent rectal cancers underwent preoperative external radiotherapy with 46-50 Gy. Six to 8 weeks later radical pelvic surgery was attempted, and was combined with intraoperative electron beam radiotherapy (15-20 Gy) in 66 patients. The patients were followed closely to evaluate complication rate, local and distant recurrence rate and survival. Results: Surgery with no macroscopic tumour remaining was obtained in 65% of the patients with no postoperative deaths. Pelvic infection was the major complication (21%). Although the observation time is short (3-60 months), the local recurrence rate seems low (22%) and survival seems promising (about 60% at 4 years) in patients with complete tumour resection, in contrast to patients with residual tumour (none living at 4 years). Conclusions: The combined modality treatment with preoperative external radiotherapy and extensive pelvic surgery with IORT is sufficiently promising to start a randomized trial on the clinical value of IORT as a boost treatment in the multidisciplinary approach to this disease

Full text: Current approaches to successful management of malignancy include combined modalities of treatment with ionizing radiation and anticancer drugs. Together with tumor cells normal tissues and cells are also submitted to the damaging effect of these agents, creating thus a probability for development of secondary neoplastic processes. The aim of the present study was to investigate the rate of chromosome damage at different modalities of combined exposures to gamma irradiation and cyclophosphamide(CY) of mice. Chromosomal aberration frequency in metaphase bone marrow cells was used as a measure to evaluate the effect. Combination treatments with 3 Gy gamma irradiation and 20 mg/kg cyclophosphamide were given at different intervals - simultaneously or at 12 hr interval, in order to establish the conditions and factors influencing the rate of chromosome damage. The distribution of different types of chromosome aberrations, such as chromatid fragments, chromatid exchanges, chromosome fragments and chromosome exchanges was analyzed. The results showed a high synergistic effect at simultaneous treatment with both agents if assessed by the index of aberrations per cell (%). An attempt has been made to suggest a possible explanation of the effects at different combined treatments related to the type of induced chromosomal aberrations. (author)

1976-03-01

This study aims to determine the best combination of irradiation-hot water and irradiation-low temperature storage as treatments to help achieve longer shelf-life extension of fruits with export value such as bananas and mangoes. Results have shown the combined irradiation and hot water treatment as a better treatment for mangoes over that of combined irradiation (50kr) and low temperature storage (15 0 C) or of single treatments with irradiation, refrigeration or hot water. A much lower dose of 30 krad was found to give the longest extension in shelf-life in mangoes subjected to irradiation and hot (55 0 C) water treatment. No significant differences in the organoleptic properties were found in the samples given the combination treatment when compared to samples given no treatment at all. The extension in shelf-life may be attributed to the synergistic effect of the treatments, which could have affected the senescence of the fruit and likewise controlled the growth of rot-causing microorganisms. Similar work was also done on bananas but the results are still preliminary

Combination of pharmacotherapy and psychotherapy in the treatment of chronic depression: A systematic review and meta-analysis

Science.gov (United States)

2012-01-01

Background Chronic depression represents a substantial portion of depressive disorders and is associated with severe consequences. This review examined whether the combination of pharmacological treatments and psychotherapy is associated with higher effectiveness than pharmacotherapy alone via meta-analysis; and identified possible treatment effect modifiers via meta-regression-analysis. Methods A systematic search was conducted in the following databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, ISI Web of Science, BIOSIS, PsycINFO, and CINAHL. Primary efficacy outcome was a response to treatment; primary acceptance outcome was dropping out of the study. Only randomized controlled trials were considered. Results We identified 8 studies with a total of 9 relevant comparisons. Our analysis revealed small, but statistically not significant effects of combined therapies on outcomes directly related to depression (BR = 1.20) with substantial heterogeneity between studies (I² = 67%). Three treatment effect modifiers were identified: target disorders, the type of psychotherapy and the type of pharmacotherapy. Small but statistically significant effects of combined therapies on quality of life (SMD = 0.18) were revealed. No differences in acceptance rates and the long-term effects between combined treatments and pure pharmacological interventions were observed. Conclusions This systematic review could not provide clear evidence for the combination of pharmacotherapy and psychotherapy. However, due to the small amount of primary studies further research is needed for a conclusive decision. PMID:22694751

Enhanced bonding of chitosan to implant quality titanium via four treatment combinations

Martin, Holly J.; Schulz, Kirk H.; Bumgardner, Joel D.; Schneider, Judith A.

2008-01-01

Bioactive coatings have been investigated to enhance the integration of orthopaedic and dental-craniofacial implants in the surrounding bone tissue. Chitosan has been shown to possess many properties desirable in implant coatings, such as cell attachment and growth, and encouraging ordered bone tissue formation. Previous studies have produced methods to deposit chitosan onto a titanium surface using both two-step and three-step reaction schemes. In the current study, two different titanium surface treatments were evaluated for determining the strength of chitosan coatings bonded to titanium via two reaction processes. The chitosan coatings produced from the four treatment combinations were examined using X-ray Photoelectron Spectroscopy, which demonstrated that the final coatings were similar in composition to the previously reported coatings. Coatings examined by nano-indentation, exhibited hardness (0.19 ± 0.08 GPa) and elastic modulus (4.90 ± 1.82 GPa) values similar to the hardness and elastic modulus values previously reported. Scanning Electron Microscopy examination of the nano-indentation marks revealed cracks only at sites of applied stress, demonstrating that the chitosan coatings were able to absorb the applied stress. Bulk adhesion of the chitosan coatings demonstrated significant increases in bond strength (19.50 ± 1.63 MPa) over previously reported data (1.5-1.8 MPa), but no significant differences were seen between the four treatment combinations. Contact angle testing demonstrated that the chitosan coatings were more hydrophobic (98.0 ± 3.6 deg.) than published values (76.4 ± 5.1 deg.). Overall, mechanical testing demonstrated that, while the bulk properties of the chitosan coating were unaffected by the four treatment combinations, the bulk adhesion of the chitosan coating was greatly increased and high quality coatings were produced

Combination therapy has been proposed as an alternative therapeutic approach for the treatment of Chagas disease. In this study, we evaluated the effect of treatment with benznidazole combined with E1224 (ravuconazole prodrug) in an experimental murine model of acute infection. The first set of experiments assessed the range of E1224 doses required to induce parasitological cure using Trypanosoma cruzi strains with different susceptibilities to benznidazole (Y and Colombian). All E1224 doses were effective in suppressing the parasitemia and preventing death; however, parasitological cure was observed only in mice infected with Y strain. Considering these results, we evaluated the effect of combined treatment against Colombian, a multidrug-resistant T. cruzi strain. After exclusion of antagonistic effects using in vitro assays, infected mice were treated with E1224 and benznidazole in monotherapy or in combination at day 4 or 10 postinoculation. All treatments were well tolerated and effective in suppressing parasitemia; however, parasitological and PCR assays indicated no cure among mice treated with monotherapies. Intriguingly, the outcome of combination therapy was dependent on treatment onset. Early treatment using optimal doses of E1224-benznidazole induced a 100% cure rate, but this association could not eliminate a well-established infection. The beneficial effect of combination therapy was evidenced by further reductions of the patent parasitemia period in the group receiving combined therapy compared with monotherapies. Our results demonstrated a positive interaction between E1224 and benznidazole against murine T. cruzi infection using a multidrug-resistant strain and highlighted the importance of a stringent experimental model in the evaluation of new therapies.

2015-01-01

Commercial apple juice inoculated with Escherichia coli was treated with UV-C, heat (55°C) and dimethyl dicarbonate – DMDC (25, 50, and 75 mg/L)-, applied separately and in combination, in order to investigate the possibility of synergistic lethal effects. The inactivation levels resulting from each treatment applied individually for a maximum treatment time of 3.58 min were limited, reaching 1.2, 2.9, and 0.06 log10 reductions for UV, heat, and DMDC (75 mg/L), respectively. However, all the investigated combinations resulted in a synergistic lethal effect, reducing the total treatment time and UV dose, with the synergistic lethal effect being higher when larger concentrations of DMDC were added to the apple juice. The addition of 75 mg/L of DMDC prior to the combined UV-C light treatment at 55°C resulted in 5 log10 reductions after only 1.8 min, reducing the treatment time and UV dose of the combined UV-Heat treatment by 44%.

Purpose: Radiation treatment of gynecological neoplasms, such as cervical carcinoma, usually combines external radiation therapy with one or more intracavitary brachytherapy applications. Although the dose from external beam radiation therapy and brachytherapy can be calculated and displayed in 3D individually, the dose distributions are not combined. At most, combined point doses are calculated for select points using various time-dose models. In this study, we present a methodology to combine external beam and brachytherapy treatments for gynecological neoplasms. Material and Methods: Three dimensional bio-effect treatment planning to obtain complication probability has been outlined. CT scans of the patient's pelvis with the gynecological applicator in place are used to outline normal tissue and tumor volumes. 3D external beam and brachytherapy treatment plans are developed separately and an external beam dose matrix and a brachytherapy dose matrix was calculated. The dose in each voxel was assumed to be homogeneous. The physical dose in each voxel of the dose matrix was then converted into extrapolated response dose (ERD) based on the linear quadratic model that accounts for the dose per fraction, number of fractions, dose rate, and complete or incomplete repair of sublethal damage (time between fractions). The net biological dose delivered was obtained by summing the ERD grids from external beam and brachytherapy since there was complete repair of sublethal damage between external beam and brachytherapy treatments. The normal tissue complication probability and tumor control probability were obtained using the biological dose matrix based on the critical element model. Results: The outlined method of combining external beam and brachytherapy treatments was implemented on gynecological treatments using an applicator for brachytherapy treatments. Conclusion: Implementation of the biological dose calculation that combine different modalities is extremely useful

The current study investigated the longitudinal course of symptoms in bipolar disorder among individuals receiving optimal treatment combining pharmacotherapy and psychotherapy, as well as predictors of the course of illness. A total of 160 participants with bipolar disorder (bipolar I disorder: n = 115; bipolar II disorder: n = 45) received regular pharmacological treatment, complemented by a manualized, evidence-based psychosocial treatment - that is, cognitive behavioral therapy or psychoeducation. Participants were assessed at baseline and prospectively for 72 weeks using the Longitudinal Interval Follow-up Evaluation (LIFE) scale scores for mania/hypomania and depression, as well as comparison measures (clinicaltrials.gov identifier: NCT00188838). Over a 72-week period, patients spent a clear majority (about 65%) of time euthymic. Symptoms were experienced more than 50% of the time by only a quarter of the sample. Depressive symptoms strongly dominated over (hypo)manic symptoms, while subsyndromal symptoms were more common than full diagnosable episodes for both polarities. Mixed symptoms were rare, but present for a minority of participants. Individuals experienced approximately six significant mood changes per year, with a full relapse on average every 7.5 months. Participants who had fewer depressive symptoms at intake, a later age at onset, and no history of psychotic symptoms spent more weeks well over the course of the study. Combined pharmacological and adjunctive psychosocial treatments appeared to provide an improved course of illness compared to the results of previous studies. Efforts to further improve the course of illness beyond that provided by current optimal treatment regimens will require a substantial focus on both subsyndromal and syndromal depressive symptoms. © 2014 John Wiley & Sons A/S.

Intermittent preventive treatment (IPT) has recently been accepted as an important component of the malaria control strategy. Intermittent preventive treatment for children (IPTc) combined with timely treatment of malaria related febrile illness at home to reduce parasite prevalence and malaria morbidity in children aged between six and 60 months in a coastal community in Ghana. This paper reports persistence of reduced parasitaemia two years into the intervention. The baseline and year-one-evaluation findings were published earlier. The main objective in the second year was to demonstrate whether the two interventions would further reduce parasite prevalence and malaria-related febrile illness in the study population. This was an intervention study designed to compare baseline and evaluation findings without a control group. The study combined home-based delivery of intermittent preventive treatment for children (IPTc) aged 6 - 60 months and home treatment of suspected febrile malaria-related illness within 24 hours. All children aged 6-60 months received home-based delivery of intermittent preventive treatment using amodiaquine + artesunate, delivered at home by community assistants every four months (6 times in 24 months). Malaria parasite prevalence surveys were conducted before the first and after the third and sixth IPTc to the children. The evaluation surveys were done four months after the third and sixth IPTc was given. Parasite prevalence which reduced from 25% to 3.0% at year-one evaluation had reduced further from 3% to 1% at year-two-evaluation. At baseline, 13.8% of the children were febrile (axilary temperature of ≥ 37.5 °C) compared to 2.2% at year-one-evaluation while 2.1% were febrile at year-two-evaluation. The year-two-evaluation result indicates that IPTc given three times in a year (every four months) combined with timely treatment of febrile malaria illness, is effective to reduce malaria parasite prevalence in children aged 6 to 60 months

An analysis of literature shows that there is still little evidence concerning the efficacy of electroconvulsive therapy (ECT) combined with antipsychotic therapy in a group of treatment-resistant schizophrenia patients. More precisely, its influence on cognitive functions is still equivocal. The aim of this study was to assess the influence of ECT combined with antipsychotic therapy on working memory, attention, and executive functions in a group of treatment-refractory schizophrenia patients. Twenty-seven patients completed the study: 14 men and 13 women, aged 21 to 55 years (mean age, 32.8 years), diagnosed with treatment-resistant schizophrenia. Each patient underwent a course of ECT sessions and was treated with antipsychotic medications. Before the ECT and within 3 days after the last ECT session, the participants were assessed with the following neuropsychological tests: Trail Making Test (TMT) and Wisconsin Cart Sorting Test (WCST). There were no significant differences in the TMT and WCST results after combined ECT and antipsychotic therapy in treatment-refractory schizophrenia patients. According to the results of the neuropsychological tests, there was no decline in attention, executive functions, or working memory. The current study shows no significant difference in attention, working memory, or executive functions after treatment with a combination of electroconvulsive and antipsychotic therapy. This suggests that combined electroconvulsive therapy may not have a negative influence on the neuropsychological functioning of patients with treatment resistant schizophrenia.

Full Text Available Abstract Background Chronic depressions represent a substantial part of depressive disorders and are associated with severe consequences. Several studies were performed addressing the effectiveness of psychotherapeutic, pharmacological, and combined treatments for chronic depressions. Yet, a systematic review comparing the effectiveness of multiple treatment options and considering all subtypes of chronic depressions is still missing. Methods/Design Aim of this project is to summarize empirical evidence on efficacy and effectiveness of treatments for chronic depression by means of a systematic review. The primary objectives of the study are to examine, which interventions are effective; to examine, if any differences in effectiveness between active treatment options exist; and to find possible treatment effect modifiers. Psychotherapeutic, pharmacological, and combined treatments will be considered as experimental interventions and no treatment, wait-list, psychological/pharmacological placebo, treatment as usual, and other active treatments will be seen as comparators. The population of patients will include adults with chronic major depression, dysthymia, double depression, or recurrent depression without complete remission between episodes. Outcomes of the analyses are depressive symptoms, associated consequences, adverse events, and study discontinuation. Only randomized controlled trials will be considered. Discussion Given the high prevalence and serious consequences of chronic depression and a considerable amount of existing primary studies addressing the effectiveness of different treatments the present systematic review may be of high relevance. Special attention will be given to the use of current methodological standards. Findings are likely to provide crucial information that may help clinicians to choose the appropriate treatment for chronically depressed patients.

Full Text Available Background: hypertension is one of the main cardiovascular risk factors, so its control improves the life expectancy of patients.Objective: to assess the effects of a treatment combining medication with auricular therapy and phyto-therapy in hypertensive patients assisted at the health area of ”Romárico Oro” Polyclinic, in Puerto Padre, Las Tunas province.Methods: an intervention study was carried out in 68 hypertensive patients of the health area of “Romárico Oro” Polyclinic in Puerto Padre from April, 2013 to April, 2014. The patients were distributed at random into two equal groups; the first received medication combined with auricular therapy and phyto-therapy, while the second one received only medication. The statistical analysis was done by means of Statistic system, t-student and Chi-Square tests were used and p< or =0.05 was considered as level of statistical significance.Results: by the end of the intervention, 73, 53% of the patients of the group with the combination of drug treatment and auricular therapy and phyto-therapy were controlled. In this group, the diastolic filling pressure diminished to 2, 2 mm Hg and the systolic gradient to 3, 66 mm, regarding the group treated only with drugs. Only one patient, representing the 2, 94% showed adverse reaction to the natural and traditional treatment.Conclusions: the combination of medication with auricular therapy and phyto-therapy proved to be effective, corroborated by a significant decrease of quantity of crisis, diastolic and systolic filling pressure values and increase of number of patients with their disease controlled; the report of only one complication shows the innocuousness of the auricular therapy and phyto-therapy treatment.

In this study, we examined the therapeutic potential of anti-Sclerostin Antibody (Scl-Ab) and bisphosphonate treatments for the bone fragility disorder Osteogenesis Imperfecta (OI). Mice with the Amish OI mutation (Col1a2 G610C mice) and control wild type littermates (WT) were treated from week 5 to week 9 of life with (1) saline (control), (2) zoledronic acid given 0.025mg/kg s.c. weekly (ZA), (3) Scl-Ab given 50mg/kg IV weekly (Scl-Ab), or (4) a combination of both (Scl-Ab/ZA). Functional outcomes were prioritized and included bone mineral density (BMD), bone microarchitecture, long bone bending strength, and vertebral compression strength. By dual-energy absorptiometry, Scl-Ab treatment alone had no effect on tibial BMD, while ZA and Scl-Ab/ZA significantly enhanced BMD by week 4 (+16% and +27% respectively, P<0.05). Scl-Ab/ZA treatment also led to increases in cortical thickness and tissue mineral density, and restored the tibial 4-point bending strength to that of control WT mice. In the spine, all treatments increased compression strength over controls, but only the combined group reached the strength of WT controls. Scl-Ab showed greater anabolic effects in the trabecular bone than in cortical bone. In summary, the Scl-Ab/ZA intervention was superior to either treatment alone in this OI mouse model, however further studies are required to establish its efficacy in other preclinical and clinical scenarios.

Full Text Available Infection with the filarial nematode Wuchereria bancrofti can lead to lymphedema, hydrocele, and elephantiasis. Since adult worms cause pathology in lymphatic filariasis (LF, it is imperative to discover macrofilaricidal drugs for the treatment of the infection. Endosymbiotic Wolbachia in filariae have emerged as a new target for antibiotics which can lead to macrofilaricidal effects. In Ghana, a pilot study was carried out with 39 LF-infected men; 12 were treated with 200 mg doxycycline/day for 4 weeks, 16 were treated with a combination of 200 mg doxycycline/day + 10 mg/kg/day rifampicin for 2 weeks, and 11 patients received placebo. Patients were monitored for Wolbachia and microfilaria loads, antigenaemia, and filarial dance sign (FDS. Both 4-week doxycycline and the 2-week combination treatment reduced Wolbachia load significantly. At 18 months posttreatment, four-week doxycycline resulted in 100% adult worm loss, and the 2-week combination treatment resulted in a 50% adult worm loss. In conclusion, this pilot study with a combination of 2-week doxycycline and rifampicin demonstrates moderate macrofilaricidal activity against W. bancrofti.

This study investigates the possible benefits of radiofrequency ablation (RFA) in patients with non-resectable colorectal liver metastases. This phase II study, originally started as a phase III design, randomly assigned 119 patients with non-resectable colorectal liver metastases between systemic treatment (n = 59) or systemic treatment plus RFA ( ± resection) (n = 60). Primary objective was a 30-month overall survival (OS) rate >38% for the combined treatment group. The primary end point was met, 30-month OS rate was 61.7% [95% confidence interval (CI) 48.2-73.9] for combined treatment. However, 30-month OS for systemic treatment was 57.6% (95% CI 44.1-70.4), higher than anticipated. Median OS was 45.3 for combined treatment and 40.5 months for systemic treatment (P = 0.22). PFS rate at 3 years for combined treatment was 27.6% compared with 10.6% for systemic treatment only (hazard ratio = 0.63, 95% CI 0.42-0.95, P = 0.025). Median progression-free survival (PFS) was 16.8 months (95% CI 11.7-22.1) and 9.9 months (95% CI 9.3-13.7), respectively. This is the first randomized study on the efficacy of RFA. The study met the primary end point on 30-month OS; however, the results in the control arm were in the same range. RFA plus systemic treatment resulted in significant longer PFS. At present, the ultimate effect of RFA on OS remains uncertain.

The potential of using antagonistic yeast Metschnikowia pulcherrimas alone or in combination with ultraviolet-C (UV-C) treatment for controlling Alternaria rot of winter jujube, and its effects on postharvest quality of fruit was investigated. The results showed that spore germination of Alternaria alternata was significantly inhibited by each of the 3 doses (1, 5, and 10 kJ m(-2) ) in vitro. In vivo, UV-C treatment (5 kJ m(-2) ) or antagonist yeast was capable of reducing the percentage of infected wounds and lesion diameter in artificially inoculated jujube fruits, however, in fruit treated with combination of UV-C treatment and M. pulcherrima, the percentage of infected wounds and lesion diameter was only 16.0% and 0.60 cm, respectively. The decay incidence on winter jujube fruits treated with the combination of UV-C treatment and M. pulcherrima was 23% after storage at 0 ± 1 °C for 45 d followed by 22 °C for 7 d. None of the treatments impaired quality parameters of jujube fruit. Thus, the combination of UV-C radiation and M. pulcherrima could be an alternative to synthetic fungicides for controlling postharvest Alternaria rot of winter jujube. © 2014 Institute of Food Technologists®

To evaluate the treatment methods of mandibular symphyseal fracture combined with dislocated intracapsular condylar fractures (MSF&DICF) and to compare the effect of different treatment methods of condylar fractures. Twenty-eight patients with MSF&DICF were included in this study. Twenty-two sites were treated by open reduction, and all the medial condylar fragments were fixed with titanium screws; whereas the other 22 sites underwent close treatment. The surgical effect between these 2 groups was compared based on clinical examination and radiographic examination results. Seventeen of 22 condyle fractures were repositioned in the surgery group, whereas 4 of 22 condyle fractures were repositioned in the close treatment group. Statistical difference was observed between these 2 groups (P condyle fractures should be treated by surgical reduction with the maintenance of the attachment of lateral pterygoid muscle, which is beneficial to repositioning the dislocated condyle to its original physiological position, to closure of the mandibular lingual gap, to restore the mandibular width.

Adolescents with anorexia nervosa who have obsessive-compulsive (OC) features respond poorly to family-based treatment (FBT). This study evaluated the feasibility of combining FBT with either cognitive remediation therapy (CRT) or art therapy (AT) to improve treatment response in this at-risk group. Thirty adolescents with anorexia nervosa and OC features were randomized to 15 sessions of FBT + CRT or AT. Recruitment rate was 1 per month, and treatment attrition was 16.6% with no differences between groups. Suitability, expectancy and therapeutic relationships were acceptable for both combinations. Correlations between changes in OC traits and changes in cognitive inefficiencies were found for both combinations. Moderate changes in cognitive inefficiencies were found in both groups but were larger in the FBT + AT combination. This study suggests that an RCT for poor responders to FBT because of OC traits combining FBT with either CRT or AT is feasible to conduct.

Full Text Available Abstract Background Hip fracture is associated with pronounced morbidity and excess mortality in elderly women with postmenopausal osteoporosis. Many drugs have been developed to treat osteoporosis and to reduce the risk of osteoporotic fractures. We investigated the effects of combined alendronate and vitamin D3 treatment on bone mass and fracture load at the femoral neck in ovariectomized (OVX rats, and evaluated the relationship between bone mass parameters and femoral neck strength. Methods Thirty 12-week-old female rats underwent either a sham-operation (n = 6 or OVX (n = 24. Twenty weeks later, OVX rats were further divided into four groups and received daily doses of either saline alone, 0.1 mg/kg alendronate, 0.1 μg/kg calcitriol, or a combination of both two drugs by continuous infusion via Alzet mini-osmotic pumps. The sham-control group received saline alone. After 12 weeks of treatment, femoral necks were examined using peripheral quantitative computed tomography (pQCT densitometry and mechanical testing. Results Saline-treated OVX rats showed significant decreases in total bone mineral content (BMC (by 28.1%, total bone mineral density (BMD (by 9.5%, cortical BMC (by 26.3%, cancellous BMC (by 66.3%, cancellous BMD (by 29.0% and total cross-sectional bone area (by 30.4% compared with the sham-control group. The combined alendronate and calcitriol treatments improved bone loss owing to estrogen deficiency. On mechanical testing, although OVX significantly reduced bone strength of the femoral neck (by 29.3% compared with the sham-control group, only the combined treatment significantly improved the fracture load at the femoral neck in OVX rats to the level of the sham-controls. The correlation of total BMC to fracture load was significant, but that of total BMD was not. Conclusion Our results showed that the combined treatment with alendronate and calcitriol significantly improved bone fragility of the femoral neck in OVX osteopenic

Full Text Available The curative effect of edaravone combined with ozagrel sodium on acute ischemic stroke beyond the time window of thrombolysis was investigated. A total of 100 patients with acute ischemic stroke beyond the time window of thrombolysis were admitted in our hospital from December 2010 to December 2012. The patients were divided into combined treatment group (N = 50 and ozagrel sodium monotherapy group (control group, N = 50. After 14 days' treatment, total effective rate of the combined treatment group (92% , 46/50 was significantly higher than that of the control group (66% , 33/50; χ2 = 10.780, P = 0.029. After treatment, the nerve function defect score was significantly improved in comparison with before treatment in both groups, but the improvement in combined treatment group (8.21 ± 3.58 was much better than that in the control group (14.60 ± 4.39; t = 7.976, P = 0.000. Therefore, treatment of edaravone combined with ozagrel sodium for patients with acute ischemic stroke beyond the thrombolytic time window can significantly raise the curative effect and improve the neurological function of these patients.

The aim of this study was to evaluate the efficacy of acupuncture and bee venom acupuncture (BVA) for idiopathic Parkinson's disease (IPD) through a sham-controlled trial. We also investigated whether there is a sustained therapeutic effect by completing follow-up assessments after treatment completion. A single center, double-blind, three-armed randomized controlled trial. This study was performed at a university hospital in Seoul, Republic of Korea. Seventy-three (73) patients with IPD were the subjects. They were randomly assigned to the active treatment group, sham treatment group, or conventional treatment group. The active treatment group received acupuncture and BVA and the sham group received sham acupuncture and normal saline injections, twice a week for 12 weeks. The conventional treatment group maintained anti-parkinsonian drugs without additional intervention. The Unified Parkinson's Disease Rating Scale (UPDRS) part II and part III score, postural instability and gait disturbance (PIGD) score, gait speed and number, Parkinson's Disease Quality of Life Questionnaire, Beck Depression Inventory, and postural stability at baseline and at 12, 16, and 20 weeks. Sixty-three (63) patients provided a complete data of assessments, including a final follow-up. After 12 weeks of treatment, a significant difference was observed between the active treatment group and the conventional treatment group. After the end of the treatment, the treatment effects were maintained significantly in the active treatment group only. It is suggested that the combined treatment of acupuncture and BVA might be safe and useful adjunctive treatment for patients with IPD.

Composite samples of sludge obtained from a pharmaceutical factory were analysed for their pollution characteristics. The samples were then treated by integrated aerobic biological and physicochemical methods. The analysis revealed that the BOD and COD of the sludge liquor were high, as well as were the levels of solids concentration, nitrogen, phosphorus and bacterial count. These showed that sludge from this industry had a high pollution potential, and therefore needed treatment before disposal or reuse in other applications. Percentage solids reduction achieved were in the range of 26.1 to 29% of total soluble solids, 26.1 to 33% of suspended solids, and 43 to 52% of volatile solids, BOD and COD reductions were in the range of 96.1 to 98.2% and 96.8 to 98.4% respectively. Ammonia nitrogen reductions in this sludge were about 85.2 to 93.3%. Total nitrogen and phosphorus were also found to be appreciably reduced by the combined aerobic and physicochemical treatment methods. (author)

Recently, photodynamic therapy (PDT) has been used for the treatment of festering wounds and trophic ulcers. An important advantage of PDT is its ability to affect bacterial cultures that are resistant to antibiotics. However the use of PDT alone does not usually guarantee a stable antiseptic effect and cannot prevent an external infection of wounds and burns. In this work attention is focused on the healing of the extensive soft tissues wounds with combined laser therapy (LT) and PDT treatment. At the first stage of this process festering tissues (for example spacious purulent wounds with area more than 100 cm2) were illuminated with high-energy laser beam (with power 20 W) in continues routine. The second stage involves “softer” PDT affect, which along with the completion stages of destruction pathological cells, stimulating the process of wound granulation and epithelization. Also, according to our previous results, photosensitizer (photoditazin) is introduced inside the wound with different amphiphilic polymers for increasing the PDT efficacy.

To evaluation the clinical effect of combination of traditional Chinese medicine and western medicine on Bell's palsy. 83 patients with Bell's palsy were randomly divided into two groups (trail group 54 cases and control group 29 cases). Patients in two groups were treated with medicine, acupuncture, physiotherapy, while patients in the trail group were treated with massage and functional exercise as the same time. The results of both groups were evaluated according to Portmann's Simple Scale. The score before treatment of trail group was 2.907 +/- 1.794, while control group was 2.931 +/- 2.034. And the score after treatment of trail group was 18.593 +/- 1.743, while control group was 9.862 +/- 3.091. Score of the function of facial muscles obtained from trail group was distinctly higher than that was from the control group (P Bell's palsy with combination of traditional Chinese medicine and western medicine. The improvement of facial muscles' motive function pre- and post-treatment and quantitative evaluation of curative effect can be objectively obtained by evaluation of facial muscles' function.

The most efficacious treatments for social anxiety disorder (SAD) are the SSRIs and cognitive therapy (CT). Combined treatment is advocated for SAD but has not been evaluated in randomized trials using CT and SSRI. Our aim was to evaluate whether one treatment is more effective than the other and whether combined treatment is more effective than the single treatments. A total of 102 patients were randomly assigned to paroxetine, CT, the combination of CT and paroxetine, or pill placebo. The medication treatment lasted 26 weeks. Of the 102 patients, 54% fulfilled the criteria for an additional diagnosis of avoidant personality disorder. Outcomes were measured at posttreatment and 12-month follow-up assessments. CT was superior to paroxetine alone and to pill placebo at the end of treatment, but it was not superior to the combination treatment. At the 12-month follow-up, the CT group maintained benefits and was significantly better than placebo and paroxetine alone, whereas there were no significant differences among combination treatment, paroxetine alone, and placebo. Recovery rates at 12 months were much higher in the CT group (68%) compared to 40% in the combination group, 24% in the paroxetine group, and 4% in the pill placebo group. CT was the most effective treatment for SAD at both posttreatment and follow-up compared to paroxetine and better than combined treatment at the 12-month follow-up on the Liebowitz Social Anxiety Scale. Combined treatment provided no advantage over single treatments; rather there was less effect of the combined treatment compared to CT alone. © 2016 The Author(s) Published by S. Karger AG, Basel.

Combined treatment of solar energy and gamma irradiation to eliminate pathogenic bacteria in dewatered sludge. A combined treatment of solar energy and gamma irradiation has been done to eliminate the pathogenic microbes contaminating dewatered sludge. Samples were collected during dry season, i.e. from June to September 1985. To reduce the water content from 70% to 20%, solar energy from sun rays was used, i.e. from 9 a.m. to 2 p.m. for 4 days. Total bacterial count coliform bacteria Escherichia coli, Fecal Streptococcus, Enterobacteriaceae, and Pseudomonas sp were found to be 7.4x10 8 per g, 4.1x10 3 per g, 4.5x10 2 per g, 3.1x10 5 per g, 3.6x10 4 per g, and 5.4x10 3 per g of samples respectively. The combined treatment could reduce the irradiation dose needed to eliminate the pathogenic microbes of samples investigated from 6 to 2 kGy. (author). 5 figs, 11 refs

Groundwater wells containing large concentrations of ferrous iron face serious clogging problems as a result of biotic iron oxidation. Following a short time after their start off, wells get clogged, and their production efficiency drop significantly up to a total obstruction, making cleanup and rehabilitation an economic burden. The present study was undertaken to test an experimental combined treatment (chemical and biological) for future prevention or rehabilitation of clogged wells. Sphaerotilus natans (an iron-oxidizing bacterium) freshly isolated from a deep well was grown to form biofilms on two systems: coupons and sand buried miniature wedge wire screen baskets. A combined chemical-biological treatment, applied at laboratory scale by use of glycolic acid (2%) and isolated bacteriophages against Sphaerotilus natans (SN1 and ER1-a newly isolated phage) at low multiplicity of infection (MOI), showed inhibition of biofilm formation and inactivation of the contaminant bacteria. In addition to complete inactivation of S. natans planktonic bacteria by the respective phages, earlier biofilm treatment with reduced glycolic acid concentration revealed efficient exopolysaccharide (EPS) digestion allowing phages to be increasingly efficient against biofilm matrix bacteria. Utilization of this combined treatment revealed clean surfaces of a model stainless steel wedge wire screen baskets (commonly used in wells) for up to 60 days.

We have recently reported that pre-treatment, but not the post-treatment with atorvastatin showed survival benefit and improved hemodynamic functions in cecal ligation and puncture (CLP) model of sepsis in mice. Here we examined whether combined treatment with atorvastatin and imipenem after onset of sepsis can prolong survival and improve vascular functions. At 6 and 18h after sepsis induction, treatment with atorvastatin plus imipenem, atorvastatin or imipenem alone or placebo was initiated. Ex vivo experiments were done on mouse aorta to examine the vascular reactivity to nor-adrenaline and acetylcholine and mRNA expressions of α1D AR, GRK2 and eNOS. Atorvastatin plus imipenem extended the survival time to 56.00±4.62h from 20.00±1.66h observed in CLP mice. The survival time with atorvastatin or imipenem alone was 20.50±1.89h and 27.00±4.09h, respectively. The combined treatment reversed the hyporeactivity to nor-adrenaline through preservation of α1D AR mRNA/protein expression and reversal of α1D AR desensitization mediated by GRK2/Gβγ pathway. The treatment also restored endothelium-dependent relaxation to ACh through restoration of aortic eNOS mRNA expression and NO availability. In conclusion, combined treatment with atorvastatin and imipenem exhibited survival benefit and improved vascular functions in septic mice. Copyright © 2015 Elsevier Inc. All rights reserved.

The tissue tolerance doses of the maxillary sinus structures were estimated when they were subjected to treatment for maxillary cancer by the usual combination of surgery, radiotherapy, and regional arterial infusion of 5-fluorouracil. Equivalent single dose calculation was applied with irreversible tissue damage as an indicator. The retardation of epithelialization of the maxillary sinus operated upon appeared to be correlated with the dose delivered. The study indicated that 2,200 rad expressed by equivalent single dose is a safe dose level for sufficient epithelialization. The safety dose level for the bony structure, exposed by surgery, seemed to be at 1,800 rad.

Distraction osteogenesis (DO) is a technique that allows the generation of new bone in a gap between 2 vascularized bone surfaces in response to the application of graduated tensile stress across the bone gap.Distraction osteogenesis has become a routine treatment of choice to correct skeletal deformities and severe bone defects in the craniofacial complex over the past decade. Distraction osteogenesis has been successfully chosen in lengthening the maxilla and the mandible; in the maxilla and recently in the mandible, the jawbones have been distracted and widened transversely to relieve severe anterior dental crowding and transverse discrepancies between the dental arches.Distraction osteogenesis for maxillary advancement started in 1993 and is now widely used, especially in patients with skeletal Class III malocclusion caused by maxillary hypoplasia.The aim of this study was to present the efficiency of combined orthodontic and DO in the severe maxillary hypoplasia.A 35-year-old Italian man presented to our clinical practice with the chief complaint of esthetic and functionally problems because of skeletal Class III malocclusion with anterior crossbite.Considering that the severity of the skeletal discrepancy is remarkable but compensated by the DO potential, the combined orthodontic and DO treatment was considered adequate, like less invasive and equally effective.It was obtained a good alignment with the upper and lower arch dental alveolar maxillary advancement that allowed to correct the sagittal relationships.The patient was satisfied for the treatment results and had considerable improvement in his self-esteem.

Vitiligo is an acquired depigmenting disease with uncertain etiopathogenesis and the treatment modalities need to be consistently updated. To evaluate a triple-combination treatment with oral α-lipoic acid (ALA), betamethasone injection, and narrowband ultraviolet B (NB-UVB) on vitiligo. Patients with non-segmental and progressive vitiligo lesions were randomly assigned to two groups. The treatment group and the control group were respectively treated with oral ALA and placebo, in combination with betamethasone injection and NB-UVB. The effectiveness and adverse events were evaluated by investigators and patients before and after treatment. Fifty non-segmental progressive vitiligo patients were enrolled in the study. The treatment period was 6 months. In treatment group, over 40% patients achieved > 50% improvement and ≥ 5 satisfaction score by 3-month therapy (M3). This percentage increased to 90% at M6. Treatment group achieved better efficacy than control group at M3, while no difference was seen at M6. The combined treatment with oral ALA, betamethasone injection, and NB-UVB was effective and safe on non-segmental progressive vitiligo. ALA could accelerate the initial response of repigmentation.

Full Text Available Helminth infections are responsible for a considerable public health burden, yet the current drug armamentarium is small. Given the high cost of drug discovery and development, the high failure rates and the long duration to develop novel treatments, drug repurposing circumvents these obstacles by finding new uses for compounds other than those they were initially intended to treat. In the present review, we summarize in vivo and clinical trial findings testing clinical candidates and marketed drugs against schistosomes, food-borne trematodes, soil-transmitted helminths, Strongyloides stercoralis, the major human filariases lymphatic filariasis and onchocerciasis, taeniasis, neurocysticercosis and echinococcosis. While expanding the applications of broad-spectrum or veterinary anthelmintics continues to fuel alternative treatment options, antimalarials, antibiotics, antiprotozoals and anticancer agents appear to be producing fruitful results as well. The trematodes and nematodes continue to be most investigated, while cestodal drug discovery will need to be accelerated. The most clinically advanced drug candidates include the artemisinins and mefloquine against schistosomiasis, tribendimidine against liver flukes, oxantel pamoate against trichuriasis, and doxycycline against filariasis. Preclinical studies indicate a handful of promising future candidates, and are beginning to elucidate the broad-spectrum activity of some currently used anthelmintics. Challenges and opportunities are further discussed.

The effect of the broad spectrum cyclic antimicrobial peptide enterocin AS-48 combination with high-intensity pulsed-electric field (HIPEF) treatment (35 kV/cm, 150 Hz, 4 micros and bipolar mode) was tested on Salmonella enterica CECT 915 in apple juice. A response surface methodology was applied to study the bactericidal effects of the combined treatment. The process variables were AS-48 concentration, temperature, and HIPEF treatment time. While treatment with enterocin AS-48 alone up to 60 microg/ml had no effect on the viability of S. enterica in apple juice, an increased bactericidal activity was observed in combination with HIPEF treatments. Survival fraction was affected by treatment time, enterocin AS48 concentration and treatment temperature. The combination of 100 micros of HIPEF treatment, 30 microg/ml of AS-48, and temperature of 20 degrees C resulted in the lowest inactivation, with only a 1.2-log reduction. The maximum inactivation of 4.5-log cycles was achieved with HIPEF treatment for 1000 micros in combination with 60 microg/ml of AS-48 and a treatment temperature of 40 degrees C. Synergism between enterocin AS-48 and HIPEF treatment depended on the sequence order application, since it was observed only when HIPEF was applied in the presence of previously-added bacteriocin. The combined treatment could improve the safety of freshly-made apple juice against S. enterica transmission.

This paper presents the results of a study comparing the effectiveness of a beta-adrenergic blocking agent, atenolol, a monoamine oxidase inhibitor (MAO-I), phenelzine, and the combination in treatment of 61 adults with migraine headache. The goals of the study are (1) to investigate the safety of concomitant treatment of migraine with beta-blockers and phenelzine, (2) to assess whether orthostatic hypertension and other side effects would be relieved, and (3) to compare the results of this open trial of phenelzine to those of a previous study using similar methods. Phenelzine was associated with a large decrease in the frequency and severity of migraine attacks. Anxiety and depression were also reduced by phenelzine both alone, and in combination with a beta-blocker. The results show that the combination of MAO-I's and beta-blockers can be administered safely, and can lead to the reduction in the side effects with either drug alone.

Greenhouse and field experiments were conducted from 2003 to 2005 to determine the effectiveness of combining releases of two predatory mite species, Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus (McGregor), and a reduced-risk miticide, Acramite (bifenazate), for control of twospotted spider mite (TSSM) (Tetranychus urticae Koch) in strawberries. In the greenhouse experiment, a combination treatment of P. persimilis and N. californicus was compared with single treatments of each species, Acramite application, and untreated control. All treatments significantly reduced TSSM numbers compared with the control. Field studies employed two approaches: one investigating the same five treatments as the greenhouse experiment and a second, comparing combination treatments of P. persimilis/N. californicus, Acramite/N. californicus, and Acramite/P. persimilis to single treatments of each and to control plots. Among the combination treatments, the P. persimilis/N. californicus treatment significantly reduced TSSM numbers compared with the control, but was not as effective as N. californicus alone during the 2003-2004 field season. Also, combination treatments of Acramite/N. californicus, and Acramite/P. persimilis significantly reduced TSSM populations compared with the control. These findings indicate that all three combination treatments are promising options for TSSM control in strawberries for growers in northern Florida and other strawberry producing areas of the world.

Full Text Available Abstract Background Intermittent preventive treatment (IPT has recently been accepted as an important component of the malaria control strategy. Intermittent preventive treatment for children (IPTc combined with timely treatment of malaria related febrile illness at home to reduce parasite prevalence and malaria morbidity in children aged between six and 60 months in a coastal community in Ghana. This paper reports persistence of reduced parasitaemia two years into the intervention. The baseline and year-one-evaluation findings were published earlier. Objective The main objective in the second year was to demonstrate whether the two interventions would further reduce parasite prevalence and malaria-related febrile illness in the study population. Methods This was an intervention study designed to compare baseline and evaluation findings without a control group. The study combined home-based delivery of intermittent preventive treatment for children (IPTc aged 6 - 60 months and home treatment of suspected febrile malaria-related illness within 24 hours. All children aged 6 - 60 months received home-based delivery of intermittent preventive treatment using amodiaquine + artesunate, delivered at home by community assistants every four months (6 times in 24 months. Malaria parasite prevalence surveys were conducted before the first and after the third and sixth IPTc to the children. The evaluation surveys were done four months after the third and sixth IPTc was given. Results Parasite prevalence which reduced from 25% to 3.0% at year-one evaluation had reduced further from 3% to 1% at year-two-evaluation. At baseline, 13.8% of the children were febrile (axilary temperature of ≥37.5°C compared to 2.2% at year-one-evaluation while 2.1% were febrile at year-two-evaluation. Conclusion The year-two-evaluation result indicates that IPTc given three times in a year (every four months combined with timely treatment of febrile malaria illness, is

In this study, a novel combination treatment of armed oncolytic adenovirus expressing interleukin 12 (IL-12) and granulocyte-macrophage colony-stimulating factor (GM-CSF) with radiation was investigated for antitumor and antimetastatic effect in a murine hepatic cancer (HCa-I) model. Tumor bearing syngeneic mice were treated with radiation, armed oncolytic virus Ad-ΔE1Bmt7 (dB7) expressing both IL-12 and GM-CSF (armed dB7), or a combination of both. The adenovirus was administered by intratumoral injection 1 x 10 8 plaque forming units (PFU) per tumor in 50 μl of phosphate buffered saline (PBS) four times every other day. Tumor response to treatment was determined by a tumor growth delay assay. Metastatic potential was evaluated by a lung metastasis model. To understand the underlying mechanism, the level of apoptosis was examined as well as the change in microvessel density and expression of immunological markers: CD4+, CD8+ and Cd11c. The combination of armed dB7 and radiation resulted in significant growth delay of murine hepatic cancer, HCa-1, with an enhancement factor of 4.3. The combination treatment also resulted in significant suppression of lung metastasis. Increase of apoptosis level as well as decrease of microvessel density was shown in the combination treatment, suggesting an underlying mechanism for the enhancement of antitumor effect. Expression of immunological markers: CD4+, CD8+ and Cd11c also increased in the combination treatment. This study showed that a novel combination treatment of radiotherapy with armed oncolytic adenovirus expressing IL-12 and GM-CSF was effective in suppressing primary tumor growth. (author)

Full Text Available Current antiviral treatment strategy for chronic hepatitis B (CHB includes pegylated interferon (PEG-IFN and nucleos(tide analogues (NAs. Whether combination therapy with PEG-IFN and NAs improve therapeutic efficacy has become the key question regarding the antiviral therapy for CHB. This article reviews the recent progress in combination therapy for the management of CHB. The results indicate that the efficacy of simultaneous combination of PEG-IFN and NAs is not superior to that of PEG-IFN monotherapy in terms of HBeAg seroconversion and response after drug withdrawal. Sequential combination or switching therapy in PEG-IFN- or NAs-treated patients, as well as combination with immune cell therapy, is a promising treatment strategy.

The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Ovarian cancer. The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand-foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas.

Gray mold (Botrytis cinerea) is one of the most major fungal pathogens in paprika. Generally, gamma irradiation over 1 kGy is effective for the control of fungal pathogens; however, a significant change in fruit quality (physical properties) on paprika was shown from gamma irradiation at over 0.6 kGy (p<0.05). Therefore, in this study, the synergistic disinfection effect of the combined treatment with gamma irradiation and sodium dichloroisocyanurate (NaDCC) was investigated to reduce the gamma irradiation dose. In an artificial inoculation experiment of B. cinerea isolated from naturally-infected postharvest paprika, fungal symptoms were observed in the stem and exocarp of paprika after conidial inoculation. From the sensitivity of gamma irradiation and NaDCC, B. cinerea conidia were fully inactivated by 4 kGy of gamma irradiation (D 10 value 0.99 kGy), and were fully inactivated by 50 ppm NaDCC treatment. The fungal symptoms were not detected by the dose-dependent gamma irradiation (>4 kGy) and NaDCC (>50 ppm). As a result of the combined treatment of gamma irradiation and NaDCC, the D 10 value was significantly reduced by 1.06, 0.88, 0.77, and 0.58 kGy (p<0.05). Moreover, fungal symptoms were more significantly reduced in combined treatment groups (gamma irradiation and NaDCC) than single treatment groups (gamma irradiation or NaDCC). These results suggest that combined treatment with irradiation and NaDCC treatment can be applied to preserve quality of postharvest paprika or other fruits. - Highlights: • Paprikas were treated with irradiation and NaDCC to control gray mold. • We confirmed that the combined treatment was synergistically affected. • The treatment can contribute to a reduction of postharvest losses caused by fungi. • This combined treatment can also reduce the doses of irradiation

The spoilage of strawberries under local market conditions was investigated. It was confirmed that the major losses are due to 'leak' disease caused by Rhizopus stolonifer (Ehr. ex Fr.) Lind. It was also established that further fruit losses in summer are due to anthracnose caused by the fungus Colletotrichum acutatum Simmonds. This is the first time that the latter pathogen has been isolated and identified and recognised as a problem on strawberries in South Africa. Studies with R. stolonifer in culture showed that 46 degrees Celsius for 20 min (the previous international standard heat treatment for fruit) was disappointing, while a treatment at 50 degrees Celsius for 10 min effectively inhibited spore germination. Irradiation studies with cultures of R. stolonifer and C. acutatum showed that a dose of 200 and 100 krad, respectively, resulted in excellent inhibition of spore germination. However, irradiating in nitrogen gas resulted in a tenfold reduction in the effectiveness of the irradiation treatments. The use of nitrogen during irradiation, therefore, cannot be considered, especially where an effective control of the fungal pathogens is desired. Investigations with different cultivars clearly demonstrated the synergistic effect on disease control obtained when combining heat and irradiation treatments. The combination treatment (moist heat at 50-52 degrees Celsius for 10 min plus 200 krad), besides effectively controlling both diseases in strawberries, did not adversely affect berry quality. In simulated transport tests it was shown that a minimal amount of berry softening did occur with this treatment, but this adverse effect was negligible compared with the beneficial effect obtained from disease control. In semi-commercial experiments it was shown that the combination heat and irradiation treatment effectively controlled spoilage diseases for a period of several days from picking, thus allowing sufficient time to market the fruit under local market

Full Text Available The ability of Taenia solium to modulate the immune system likely contributes to their longevity in the human host. We tested the hypothesis that the nature of the immune response is related to the location of parasite and clinical manifestations of infection.Peripheral blood mononuclear cells (PBMC were obtained from untreated patients with neurocysticercosis (NCC, categorized as having parenchymal or subarachnoid infection by the presence of cysts exclusively within the parenchyma or in subarachnoid spaces of the brain, and from uninfected (control individuals matched by age and gender to each patient. Using multiplex detection technology, sera from NCC patients and controls and cytokine production by PBMC after T. solium antigen (TsAg stimulation were assayed for levels of inflammatory and regulatory cytokines. PBMC were phenotyped by flow cytometry ex vivo and following in vitro stimulation with TsAg.Sera from patients with parenchymal NCC demonstrated significantly higher Th1 (IFN-γ/IL-12 and Th2 (IL-4/IL-13 cytokine responses and trends towards higher levels of IL-1β/IL-8/IL-5 than those obtained from patients with subarachnoid NCC. Also higher in vitro antigen-driven TNF-β secretion was detected in PBMC supernatants from parenchymal than in subarachnoid NCC. In contrast, there was a significantly higher IL-10 response to TsAg stimulation in patients with subarachnoid NCC compared to parenchymal NCC. Although no differences in regulatory T cells (Tregs frequencies were found ex vivo, there was a trend towards greater expansion of Tregs upon TsAg stimulation in subarachnoid than in parenchymal NCC when data were normalized for the corresponding controls.T. solium infection of the subarachnoid space is associated with an enhanced regulatory immune response compared to infection in the parenchyma. The resulting anti-inflammatory milieu may represent a parasite strategy to maintain a permissive environment in the host or diminish

Combined radiation and hormone therapies have become common clinical practice in recent years for locally-advanced prostate cancers. The use of such concomitant therapy in the treatment of breast disease has been infrequently reported in the literature, but seems justified given the common hormonal dependence of breast cancer and the potential synergistic effect of these two treatment modalities. As adjuvant therapy, two strategies are used in daily clinical practice: up front aromatase inhibitors or sequentially after a variable delay of tamoxifen. These molecules may, thus, interact with radiotherapy. Retrospective studies recently published did not show any differences in terms of locoregional recurrences between concurrent or sequential radio hormonotherapy. Lung and skin fibroses due to concurrent treatment are still under debate. Nevertheless, late side effects appeared to be increased by such a treatment, particularly in hypersensitive patients identified at risk by the lymphocyte predictive test. Concurrent radio hormonotherapy should, thus, be delivered cautiously at least for these patients. This article details the potent advantages and risks of concurrent use of adjuvant hormonotherapy and radiotherapy in localized breast cancers. (authors)

Full Text Available Manar A Ghali Ophthalmology Department, Faculty of Medicine, Zagazig University, Zagazig, Egypt Purpose: To compare and evaluate the efficacy of two different surgical techniques for the treatment of near-distance disparity esotropia; combined resection–recession and recession–retroequatorial myopexy of medial rectus muscles. Patients and methods: This prospective study included 28 patients diagnosed with convergence excess esotropia who had worn their full cycloplegic refraction and/or bifocal glasses for at least 6 months and still had near-distance disparity esotropia. The patients were divided into 2 groups; Group I underwent combined bimedial rectus muscles resection 2.5 mm from the insertion end with recession based on near-angle esotropia according to current surgical tables with 1 mm add of recession for each muscle, while Group II underwent bimedial recession based on far angle combined with retroequatorial myopexy at 13–14 mm from insertion. A satisfactory result was defined as orthophoria or esotropia <10 prism diopters (∆ at near and distance with reduction of the near-distance disparity to <10 ∆. The patients were followed up for at least 2 years for stability of correction and late onset consecutive exotropia. Results: In Group I, all the patients had satisfactory alignments at near and far with residual near–far disparity ≤10 ∆, no cases of overcorrection at far was reported; while in Group II, all cases had orthophoria at far, but 4 cases (28.6% showed near–far disparity >10 ∆. Conclusion: The technique of combined resection–recession is safe, easy and more effective in the treatment of near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results though longer follow-up period is still needed. Keywords: near-distance disparity, esotropia, Ac/A ratio, retroequatorial myopexy, slanted recession

The purpose of this study is to evaluate the efficacy of the enhancement of docetaxel by pulsed focused ultrasound (pFUS) in combination with radiotherapy (RT) for treatment of prostate cancer in vivo. LNCaP cells were grown in the prostates of male nude mice. When the tumors reached a designated volume by MRI, tumor bearing mice were randomly divided into seven groups (n = 5): (1) pFUS alone; (2) RT alone; (3) docetaxel alone; (4) docetaxel + pFUS; (5) docetaxel + RT; (6) docetaxel + pFUS + RT, and (7) control. MR-guided pFUS treatment was performed using a focused ultrasound treatment system (InSightec ExAblate 2000) with a 1.5T GE MR scanner. Animals were treated once with pFUS, docetaxel, RT or their combinations. Docetaxel was given by i.v. injection at 5 mg kg −1 before pFUS. RT was given 2 Gy after pFUS. Animals were euthanized 4 weeks after treatment. Tumor volumes were measured on MRI at 1 and 4 weeks post-treatment. Results showed that triple combination therapies of docetaxel, pFUS and RT provided the most significant tumor growth inhibition among all groups, which may have potential for the treatment of prostate cancer due to an improved therapeutic ratio.

Tomato is very important vegetable crop but has short shelf life. The objective of this research was to determine the effect of ozone and packaging combination treatment on the quality and the storage life of tomato fruit. There were six treatments including: control (without ozone and packaging); without ozone and packaged with polyethylene bag; without ozone and polyethylene terephtalate punnet; with ozone but without packaging; with ozone and packaged with polyethylene bag; and with ozone and polyethylene terephtalate punnet. Each treatment was made into 3 replications. Tomato samples were harvested at turning stage. Ozone treatment was applied for 60 seconds. Tomatoes were then treated with and without packaging. The fruit were then stored at room temperature for up to 12 days. The parameters for assessment were water content, color, texture, weight loss and the population of naturally contamination Escherichia coli. Each parameter was assessed on day 0, 6 and 12 of storage. The results indicated that combination of ozone and packaging treatments significantly affected the physical and biochemical changes (water content, color, texture and weight loss) of the fruit, suppressed the microbiological contamination on the fruit and maintained fruit freshness or quality after 12 days of storage. The combination of ozone and perforated polyethylene packaging treatment was the best treatment to maintain the quality and prolonged the shelf life of tomato fruit to be 12 days at room temperature.

The tissue tolerance doses of the maxillary sinus structures were estimated when they were subjected to treatment for maxillary cancer by the usual combination of surgery, radiotherapy and regional arterial infusion of 5-fluorouracil. Equivalent single dose calculation was applied with irreversible tissue damage as an indicator. The retardation of epithelialization of the maxillary sinus operated upon appeared to be correlated with the dose delivered. The study indicated that 2,200 rad expressed by equivalent single dose is a safe dose level for sufficient epithelialization. The safety dose level for the bony structure, exposed by surgery, seemed to be at 1,800 rad. (auth.)

Full Text Available Few studies have estimated prevalence of neurocysticercosis (NCC among persons with epilepsy in sub-Saharan Africa. While the limitations of serological testing in identification of NCC are well known, the characteristics of persons who are misdiagnosed based on serology have not been explored. The first objective of this pilot study was to estimate the prevalence of NCC in epilepsy outpatients from an area of South Africa endemic for cysticercosis. The second objective was to estimate the accuracy of serological testing in detecting NCC in these outpatients and characterize sources of disagreement between serology and neuroimaging.All out-patients aged 5 or older attending the epilepsy clinic of St. Elizabeth's Hospital in Lusikisiki, Eastern Cape Province, between July 2004 and April 2005 were invited to participate. Epidemiological data were collected by local study staff using a standardized questionnaire. Blood samples were tested by ELISA for antibody and antigen for Taenia solium. Four randomly chosen, consenting participants were transported each week to Mthatha for brain CT scan. The proportion of persons with epilepsy attending St. Elizabeth clinic with CT-confirmed NCC was 37% (95% CI: 27%-48%. Using CT as the gold standard, the sensitivity and specificity of antibody testing for identifying NCC were 54.5% (36.4%-71.9% and 69.2% (52.4%-83.0%, respectively. Sensitivity improved to 78.6% (49.2%-95.3% for those with active lesions. Sensitivity and specificity of antigen testing were considerably poorer. Compared to false negatives, true positives more often had active lesions. False positives were more likely to keep pigs and to have seizure onset within the past year than were true negatives.The prevalence of NCC in South African outpatients with epilepsy is similar to that observed in other countries where cysticercosis is prevalent. Errors in classification of NCC using serology alone may reflect the natural history of NCC.

Full Text Available Heat treatment and preservative application have been widely used during postharvest storage of many fresh products, but the effect of their combination on citrus storage has rarely been investigated. In this study, the optimal heat treatment (HT conditions and HT combined with preservative treatment were investigated for Ponkan fruit (Citrus reticulata Blanco cv. Ponkan storage. Results indicated that HT at 55°C for 20 s can significantly reduce the decay rate of Ponkan fruit, and a combination of HT and 25% of the preservative dosage used in production of iminoctadine tris (albesilate, 2,4-dichlorophenoxyacetic acid, and imazalil significantly reduced the decay rate without affecting fruit quality. In addition, the increased fiber contents in fruit receiving the HT combined with preservative treatments may be a response preventing fungus infection and enhancing fruit storability and resistance. The above results suggested that the combination of HT and 25% of the preservative production dosage was optimal for controlling Ponkan fruit decay during storage.

Cancer is a problem of global importance, since the incidence is increasing worldwide and therapeutic options are generally limited. Thus, it becomes imperative to find new therapeutic targets as well as new molecules with therapeutic potential for tumors. Flavonoids are polyphenolic compounds that may be potential therapeutic agents. Several studies have shown that these compounds have a higher anticancer potential. Among the flavonoids in the human diet, quercetin is one of the most important. In the last decades, several anticancer properties of quercetin have been described, such as cell signaling, pro-apoptotic, anti-proliferative and anti-oxidant effects, growth suppression. In fact, it is now well known that quercetin has diverse biological effects, inhibiting multiple enzymes involved in cell proliferation, as well as, in signal transduction pathways. On the other hand, there are also studies reporting potential synergistic effects when combined quercetin with chemotherapeutic agents or radiotherapy. In fact, several studies which aim to explore the anticancer potential of these combined treatments have already been published, the majority with promising results. Actually it is well known that quercetin can act on the chemosensitization and radiosensitization but also as chemoprotective and radioprotective, protecting normal cells of the side effects that results from chemotherapy and radiotherapy, which obviously provides notable advantages in their use in anticancer treatment. Thus, all these data indicate that quercetin may have a key role in anticancer treatment. In this context, this review is focused on the relationship between flavonoids and cancer, with special emphasis on the role of quercetin.

Brain metastasis from breast cancer poses a major clinical challenge. Integrins play a role in regulating adhesion, growth, motility, and survival, and have been shown to be critical for metastatic growth in the brain in preclinical models. Cilengitide, an αvβ3/αvβ5 integrin inhibitor, has previously been studied as an anti-cancer drug in various tumor types. Previous studies have shown additive effects of cilengitide and radiation in lung cancer and glioblastoma cell lines. The ability of cilengitide to enhance the effects of radiation was examined preclinically in the setting of breast cancer to assess its possible efficacy in the setting of brain metastasis from breast cancer. Our panel of breast cells was composed of four cell lines: T-47D (ER/PR+, Her2-, luminal A), MCF-7 (ER/PR+, Her2-, luminal A), MDA-MB-231 (TNBC, basal B), MDA-MB-468 (TNBC, basal A). The presence of cilengitide targets, β3 and β5 integrin, was first determined. Cell detachment was determined by cell counting, cell proliferation was determined by MTS proliferation assay, and apoptosis was measured by Annexin V staining and flow cytometry. The efficacy of cilengitide treatment alone was analyzed, followed by assessment of combined cilengitide and radiation treatment. Integrin β3 knockdown was performed, followed by cilengitide and radiation treatment to test for incomplete target inhibition by cilengitide, in high β3 expressing cells. We observed that all cell lines examined expressed both β3 and β5 integrin and that cilengitide was able to induce cell detachment and reduced proliferation in our panel. Annexin V assays revealed that a portion of these effects was due to cilengitide-induced apoptosis. Combined treatment with cilengitide and radiation served to further reduce proliferation compared to either treatment alone. Following β3 integrin knockdown, radiosensitization in combination with cilengitide was observed in a previously non-responsive cell line (MDA-MB-231

  Acne scars can cause emotional and psychosocial disturbance to the patient. Various modalities have been used for the treatment of acne scars like punch excision, subcision, peels, microdermabrasion, unfractionated and fractioned lasers. The latest in the treatment armamentarium is microneedling. Acne scars commonly coexist with postinflammatory hyperpigmentation. A combination of microneedling and glycolic acid (GA) peels was found to give excellent results in the treatment of such scars. The aim was to study the efficacy of a combination of microneedling with glycolic peel for the treatment of acne scars in pigmented skin.   Thirty patients in the age group of 20-40 years with atrophic box type or rolling scars with postinflammatory hyperpigmentation were chosen for the study. Two groups were made. The first group comprised of 30 patients in whom only microneedling was performed once in 6 weeks for five sessions. In the second group of 30 patients, a combination of microneedling and 35% GA peels was carried out. Patients from both groups were evaluated on the basis of Echelle d'Evaluation clinique des Cicatrices d'acné classification.   Based on the objective scoring and its statistical analysis, there was significant improvement in superficial and moderately deep scars (grade 1-3). There was also improvement in skin texture, reduction in postacne pigmentation in the second group.   Microneedling is a simple, inexpensive office procedure with no downtime. It is safe in Indian skin (skin types III-IV). The combined sequential treatment with GA peel caused a significant improvement in the acne scars without increasing morbidity. © 2011 Wiley Periodicals, Inc.

The ability of normobaric oxygen and carbogen (95 percent O 2 + 5 percent CO 2 ) combined with nicotinamide to enhance the radiosensitivity of two rodent adenocarcinomas and of mouse skin and kidneys was compared with the effects of radiation in air and without the drug. A comparison of the results in tumors and normal tissues showed that significant therapeutic benefit was obtained with normobaric oxygen and carbogen combined with nicotinamide. Toxic side effects of the treatment are unlikely, as prolonged administration of nicotinamide is well tolerated in man. The combination of normobaric carbogen with nicotinamide could be an effective method of enhancing tumor radiosensitivity in clinical radiotherapy where hypoxia limits the outcome of treatment.

Full Text Available Luis Bahamondes, Ilza Monteiro, Arlete FernandesHuman Reproduction Unit, Department of Obstetrics and Gynecology, School of Medical Sciences and National Institute of Hormones and Women’s Health, University of Campinas, Campinas, BrazilAbstract: The first combined oral contraceptive (OC was launched in the US 50 years ago and was followed by another formulation introduced in Germany one year later. The most common estrogen component in current formulations is ethinylestradiol; however, many concerns have been raised with respect to this estrogen. Although the natural estrogen produced by the ovary, 17-beta estradiol, is the most potent of the estrogens, it is poorly absorbed orally, and previous attempts to use it in combined OCs have been unsuccessful due to the occurrence of irregular bleeding. Recently, a new combined OC was developed containing a natural estrogen, estradiol valerate, and a new progestin, dienogest, in a dynamic 26-day, four-phasic (estrogen stepdown and progestin stepup scheme of administration. In clinical trials, its contraceptive performance was excellent, with good cycle control and bleeding patterns compared with other combined OCs or with placebo. This review focuses predominantly on the use of an estradiol valerate-dienogest combined OC for the treatment of heavy menstrual bleeding. The findings of two large, randomized, controlled trials have shown that this combined OC constitutes an effective treatment for women with heavy menstrual bleeding, representing a new therapeutic option to reduce menstrual blood loss. Further studies are necessary to confirm these data.Keywords: dienogest, estradiol valerate, heavy menstrual bleeding, menorrhagia, contraception
