Infection of European eel, Anguilla anguilla (L.), with the nematode Anguillicoloides crassus (Kuwahara, Niimi et Itagaki, 1974) in Polish waters
The aim of this study was to determine the degree of Anguillicoloides crassus infection in European eel inhabiting Polish waters based on selected parasitic descriptors and on anatomical pathology of the swimbladder using macroscopic methods. In all, 154 European eel specimens were sampled from eleven sites in Poland and A. crassus was present in the swimbladder of 114 fish. The intensity of A. crassus infection in all the eel specimens ranged from 1 to 62 parasites at a mean value of 7.5. High values of mean infection intensity were noted in samples from Pomeranian lakes Bukowo, Łebsko, and Jamno. The health of the swimbladder was evaluated using the swimbladder degenerative index (SDI). The mean value of the SDI for all of the eel examined was 3.3, and extensively degenerated swimbladders were observed mainly in samples in the Szczecin Lagoon and from lakes. According to the individual SDI ratings, 9.1% of the eel specimens did not exhibit pathological symptoms of the swimbladder (SDI-0) and an extremely damaged (SDI-6) swimbladder was noted in 11.7% of the fish examined. In the case of eel infected with A. crassus, higher SDI values were reflected in initially increasing shares in subsequent categories. In fish that were not infected with the nematode, only 20% (8 individuals) of the swimbladders showed no symptoms of pathology (SDI-0).

Object
Management recommendations for patients with smaller-volume or newly diagnosed vestibular schwannomas (< 4 cm3) need to be based on an understanding of the anticipated natural history of the tumor and the side effects it produces. The natural history can then be compared with the risks and benefits of therapeutic intervention using a minimally invasive strategy such as stereotactic radiosurgery (SRS).

Methods
The authors reviewed the emerging literature stemming from recent recommendations to “wait and scan” (observation) and compared this strategy with published outcomes after early intervention using SRS or results from matched cohort studies of resection and SRS.

Results
Various retrospective studies indicate that vestibular schwannomas grow at a rate of 0–3.9 mm per year and double in volume between 1.65 and 4.4 years. Stereotactic radiosurgery arrests growth in up to 98% of patients when studied at intervals of 10–15 years. Most patients who select “wait and scan” note gradually decreasing hearing function leading to the loss of useful hearing by 5 years. In contrast, current studies indicate that 3–5 years after Gamma Knife surgery, 61%–80% of patients maintain useful hearing (speech discrimination score > 50%, pure tone average < 50).

Conclusions
Based on published data on both volume and hearing preservation for both strategies, the authors devised a management recommendation for patients with small vestibular schwannomas. When resection is not chosen by the patient, the authors believe that early SRS intervention, in contrast to observation, results in long-term tumor control and improved rates of hearing preservation.
Effect of pregnancy on hemangioblastoma development and progression in von Hippel-Lindau disease

Published: September 2012

Object
Prior cases suggest that pregnancy increases the development and progression of CNS hemangioblastomas and/or peritumoral cysts. To determine the effect of pregnancy on CNS hemangioblastomas and peritumoral cysts, the authors prospectively evaluated serial clinical and imaging findings in patients with von Hippel-Lindau (VHL) disease who became pregnant and compared findings during pregnancy to findings in the same patients when they were not pregnant as well as to findings from a cohort of VHL patients who did not become pregnant.

Methods
Female VHL disease patients enrolled in a prospective natural history study who were of reproductive age (16–35 years at study entrance) were included. Analysis of serial clinical and imaging findings was performed.

Results
Thirty-six consecutive female VHL disease patients harboring 177 hemangioblastomas were included (mean follow-up [± SD] 7.5 ± 2.3 years). Nine patients (25%) became pregnant (pregnancy cohort). The mean rates of development of new hemangioblastomas and peritumoral cysts in these women during pregnancy (0.4 ± 0.4 tumors/year; 0.1 ± 0.2 cysts/year) did not differ significantly (p > 0.05) from the mean rates in the same group during nonpregnant periods (0.3 ± 0.4 tumors/year; 0.1 ± −0.1 cysts/year) or from the rate in the 27 patients who did not become pregnant (the no-pregnancy cohort: 0.3 ± 0.5 tumors/year; 0.1 ± 0.2 cysts/year). Hemangioblastoma growth rates were similar (p > 0.05) during pregnancy (mean 29.8% ± 42.7% increase in volume per year) compared with during nonpregnant periods (41.4% ± 51.4%) in the pregnancy cohort and the no-pregnancy cohort (34.3% ± 55.3%). Peritumoral cyst growth rates during pregnancy (571.0% ± 887.4%) were similar (p > 0.05) to those of the no-pregnancy cohort (483.9% ± 493.9%), but the rates were significantly higher for women in the pregnancy cohort during nonpregnant periods (2373.6% ± 3392.9%; p < 0.05 for comparison with no-pregnancy cohort). There was no significant difference (p > 0.05) in the need for resection or the mean age at resection between the pregnancy (28% of hemangioblastomas in cohort; mean patient age at resection 30.2 ± 2.6 years) and no-pregnancy cohorts (19%; 32.3 ± 5.6 years).

Conclusions
Pregnancy is not associated with increased hemangioblastoma or peritumoral cyst development or progression in patients with VHL disease.
Clinical features and treatment of World Health Organization Grade II and III meningiomas in childhood: report of 23 cases
Authors: Wang Xiao-Qiang , Jiang Cheng-Chuan , Zhao Lin , Gong Ye , Hu Jie , Chen Hong 
Published: September 2012

Object
High-grade meningiomas in childhood are rare, and their clinical features are unknown. The objective of this study was to determine the clinical characteristics and prognosis of childhood high-grade meningiomas.

Methods
Twenty-three patients with childhood high-grade meningiomas were treated at the Huashan Hospital. Clinical data were collected, tumor samples were reexamined, and prognoses were attained through follow-up visits and telephone interviews. Survival probability was calculated using the Kaplan-Meier method. A 2-sided probability level of 0.05 was chosen for statistical significance.

Results
The series included 18 males and 5 females (mean age 12.1 years). The most common symptoms were headache and vomiting (43%). Three patients had accompanying neurofibromatosis Type II (NF2). The high-grade meningioma cases with NF2 had larger tumor diameters than those without NF2 (p = 0.010). The skull base was the most common tumor site (39%). Complete resections were achieved in 11 patients after their initial operations. Adjuvant radiation therapy was performed in 9 cases. Follow-up evaluations were performed for 20 patients (mean follow-up 70 months). Ten patients experienced recurrences, 2 patients had lung metastases, and 7 patients died of the recurrence. The extent of surgery was significantly related to progression-free survival (PFS; p = 0.038). A negative progesterone receptor combined with strongly positive Bcl-2 immunoreactivity was significantly related to PFS (p = 0.001) and overall survival (p = 0.002). The MIB-1 labeling index was significantly related to overall survival (p = 0.018), whereas postoperative radiation therapy was not significantly related to PFS (p = 0.087) and overall survival (p = 0.40).

Conclusions
Childhood high-grade meningioma is a rare tumor type. Childhood high-grade meningioma has a male predominance and the basilar region is the most common tumor location. Patients with these tumors have high recurrence and mortality rates. The extent of resection is an important prognosis factor. A negative progesterone receptor combined with a strongly positive Bcl-2 immunoreaction might predict cancer recurrence. The MIB-1 labeling index correlates with the prognosis, and an MIB-1 labeling index > 3% increases the risk of recurrence in childhood high-grade meningioma. More cases should be collected, and longer follow-up periods should be obtained, to evaluate the effects of postoperative radiation therapy in childhood high-grade meningioma.
Surgical management of Charcot spinal arthropathy: a single-center retrospective series highlighting the evolution of management
Authors: Jacobs W. Bradley , Bransford Richard J. , Bellabarba Carlo , Chapman Jens R. 
Published: September 2012

Object
Charcot spinal arthropathy (CSA) is an uncommon disorder that occurs in the setting of conditions with decreased protective sensation of the vertebral column, resulting in vertebral joint degeneration, pain, and deformity. Historically, CSA treatment has been fraught with high failure rates. Over time, the authors' institution has trended toward a CSA treatment paradigm of intralesional debridement, circumferential fusion, and four-rod lumbopelvic fixation. As such, the overall objectives of this study were to define the specific clinical characteristics of this rare condition and to determine whether the authors' treatment paradigm has decreased the incidence of revision due to hardware failure/presumed pseudarthrosis or the development of a new CSA over the course of the study and in comparison with historical controls.

Methods
The authors performed a retrospective review of the clinical and radiographic records for all patients with CSA treated by the Spine Service at the University of Washington between 1997 and 2009.

Results
Twenty-three patients with CSA were identified. The mean age at presentation was 43.1 years, and the mean latency between spinal cord injury and CSA diagnosis was 19.6 years. The mean follow-up was 33.1 months. Pain and progressive deformity were the major presenting symptoms. Concomitant infection was identified in 17% of patients. Patients with CSA were noted to have long initial fusion constructs spanning an average of 8.4 vertebral levels. Charcot spinal arthropathy did not occur above the level of neurological injury. The vast majority of CSA cases occurred caudally along the spinal axis, with 65% occurring within 1 level of the caudal end of the index fusion construct and 35% occurring even farther distally. Revision due to hardware failure or the development of a new CSA level occurred in 35% of patients. Rates of treatment failure requiring revision significantly decreased over the course of the study, with revision occurring in 6 (66%) of 9 patients who underwent surgery before 2002, in comparison with only 2 (14%) of 14 treated between 2002 and 2009. During a mean follow-up period of 34 months, no treatment revision occurred in the subgroup of 9 patients who underwent four-rod lumbopelvic fixation.

Conclusions
This study represents the largest reported modern surgical series of CSA patients. While revision rates were initially high and comparable to previous reports, the authors' multimodal treatment paradigm, which includes the use of bone morphogenetic protein and four-rod lumbopelvic fixation, dramatically reduced the incidence of treatment failure requiring revision over the course of the study period and represents a significant improvement in the treatment of CSA.
Long-term results after posterior fossa decompression in syringomyelia with adult Chiari Type I malformation
Authors: Alfieri Alex , Pinna Giampietro 
Published: September 2012

Object
There is little information about the long-term effectiveness and complications following decompressive surgery for syringomyelia related to Chiari malformation Type I (CM-I).

Methods
Examining long-term clinical and radiological follow-up, the authors studied a mixed retrospective and prospective single-institution cohort of 109 consecutive surgically treated adult patients with syringomyelia and CM-I. All patients underwent a standardized surgical protocol: decompression of the craniocervical junction, arachnoid exploration, and shrinkage of the cerebellar tonsils. Factors predicting outcome were investigated.

Results
The retrospective arm consisted of 41 cases treated between 1990 and 1994, and the prospective arm comprised 68 patients treated between 1994 and 2001. The mean overall age was 45.9 years, and 58.8% of the population was female. The median follow-up period was 12.7 years. The most frequent initial symptoms were pain and sensory and gait disturbances. There was no perioperative death or neurological deterioration. The comprehensive perioperative complication rate was approximately 11%, with 3 cases (2.7%) of CSF leakage. Regression analysis showed that the best combination of clinical and radiological outcome predictors was age and duration of symptoms. Clinical follow-up confirmed surgical result stability with clinical improvement of greater than 90% of the spinal and cranial manifestations over a long-term period. Two patients had radiological recurrences of syringomyelia without clinical signs 85 and 124 months after surgery.

Conclusions
Certain clinical predictors of poor clinical and radiological prognosis were identified—namely, age at time of surgery and symptom duration. The results of the study provide additional long-term data that support the effectiveness and safety of relieving CSF block at the craniocervical junction in CM-I–related syringomyelia.
Efficacy of Probiotics on Survival, Growth, Biochemical Changes and Energy Utilization Performance of <i>Macrobrachium rosenbergii</i> (De Man 1879) Post-larvae
Authors: Seenivasan C. , Radhakrishan S. , Muralisankar T. , Bhavan P. S. 
Published: September 2012

The efficacy of combined probiotics, Lactobacillus sporogenes and Saccharomyces cerevisiae (LS+SC) on survival, growth, biochemical changes and energy utilization of Macrobrachium rosenbergii post larvae (PL) was examined. Each probiotic organism was individually tested at four different concentrations (1-4%) separately. The best concentration in each probiotic species was combined and tested for its suitability in aquaculture usage. The basal diet was incorporated with probiotics, LS+SC (4:4) at five different concentrations 0% (control), 1%, 2%, 3% and 4%. These diets were fed to M. rosenbergii PL for a period of 90 days. After the feeding trail, 2% LS+SC incorporated diet had significantly (P<0.05) higher survival, WG, SGR, FCE and PER compared with other experimental groups than the control. Whereas, the FCR was significantly (P<0.05) lower in 2% LS+SC incorporated diet fed PL. Similarly the proximate composition of the protein, amino acid, carbohydrate, lipid and ash content were significantly (P<0.05) higher in 2% LS+SC incorporated diet fed PL than the control. The energy utilization parameters were significantly (P<0.05) higher in 2% LS+SC incorporated diet fed PL than the control. This study indicated that combined probiotics, LS+SC incorporated diets were beneficial for M. rosenbergii in terms of increasing growth and enhancing energy utilization performances.© 2012 JSR Publications.

Published: September 2012

This study aims to assess the comparative effects of vitamin C supplementation on lipid profiles in male and female human subjects. A total of 60 healthy individuals (male and female) were selected randomly, instructed and given the understanding of the purpose of study. The test group comprising 30 individuals were given 500mg vitamin C tablets one daily for 30 days and control group of 30 individuals were given placebo capsules(glucose 500mg) one daily for 30 days. Fasting blood samples were collected in the morning for estimation of cholesterol, triglycerides, HDL-C, LDL-C and VLDL-C on first day of the commencement of the study and second blood samples were taken after thirty days of supplementation and same estimations were carried out. Vitamin C caused reduction in serum total cholesterol and LDL cholesterol significantly but it did not have any statistically significant effect on HDL-C, VLDL-C and triglycerides. As far as gender is concerned the effect of vitamin C on lipid profile in males was not significantly different from those in females.© 2012 JSR Publications.

The condensation reaction of N-alkylidene or N-arylidene-(4-n-hexyloxy)benzoylhydrazone [L] (1-7) where, R= formaldehyde (1), acetaldehyde (2), butyraldehyde (3), cinnamaldehyde (4), 4-N,N-dimethylaminobenzaldehyde (5), 2-hydroxybenzaldehyde (6) and 4-methoxybenzaldehyde (7) with Fe(III) chloride hexahydrate afforded octahedral (8-9) [Fe(L3).nH2O] and square-pyramidal (10-14) [Fe(L2)Cl.nH2O] complexes. The complexes (8-10) were obtained in presence of pyridine and the complexes (11-14) were obtained by the direct reaction of the Schiffs bases with Fe3+ ion. The complexes were characterized by magnetic moment measurement, UV-visible, infrared, 1H-NMR and TGA (Thermo gravimetric analysis) studies. The Schiffs bases containing small alkyl group at the hydrazine moiety formed octahedral complexes, while the bulky/aryl/substituted aryl moiety, yielded five coordinated square-pyramidal complexes. The complexes were found to be quite stable and decomposition of the complexes ended with ferric oxide as final product. Complexes (10) and (13) showed no activity against all the bacteria. Complexes (8), (9) and (12) showed resistance while the complex (14) manifested intermediate antibacterial activity.© 2012 JSR Publications. ISSN: 2070-0237 (Print); 2070-0245 (Online).

The Myositis Activities Profile — Initial Validation for Assessment of Polymyositis/Dermatomyositis in the USA
Authors: ALEXANDERSON HELENE , REED ANN M. , YTTERBERG STEVEN R. 
Published: September 2012

Objective.To evaluate some measurement properties of the Myositis Activities Profile (MAP) in adult patients with polymyositis (PM) and dermatomyositis (DM) in the United States.Methods.To assess content validity, patients with PM/DM rated difficulty and importance of items of the MAP using a visual analog scale (VAS), range 0–10. For construct validity, consecutive patients with PM/DM performed the 6-item core set for disease activity including the manual muscle test (MMT) and the Health Assessment Questionnaire (HAQ), the Functional Index-2 (FI-2; muscle endurance), and the MAP plus disease effect on well-being on a VAS. Item fit within subscales was analyzed by Cronbach’s alpha. Patients with stable disease activity filled out the MAP again 1 week later.Results.The median combined difficulty and importance, 0–10, of the 31 items was 5.00 (range 2.10–5.95). One item was added, giving a 32-item MAP. Correlations between the median of subscales/single items of the MAP and the HAQ and disease effect on well-being were rs = 0.69 and rs = 0.68, respectively, with lower correlations to the MMT (rs = −0.35), and the FI-2 (rs = −0.29 to −0.47) and disease activity measures (rs = 0.36–0.41). Cronbach’s alpha coefficients for the 4 subscales varied between 0.85 and 0.95. Weighted kappa coefficients (Kw) ranged between 0.77 and 0.93 for the 4 subscales and between 0.74 and 0.83 for the 4 single items without systematic variations (p > 0.05).Conclusion.This initial validation of the MAP indicates promising measurement properties for assessing limitations in activities of daily living and participation in patients with PM/DM in the United States.
Sur la résistance chez Freud et Foucault
Authors: Canavêz Fernanda , Miranda Heraldo 
Published: August 2012

Cet article nous décrit la question de la résistance chez Freud et Foucault. Les auteurs parient sur la fertilité de la différence, afin d’entreprendre une analyse du concept de résistance qui échappe aux impératifs de la conciliation précipitée et à ceux des non-ressemblances stériles. Ainsi, on est tenté de penser que la relation entre les deux auteurs est d’un rapprochement non-conciliatoire, car il n’est pas possible de supposer une approche absolue, malgré des éléments en commun, ni un éloignement radical. Du point de vue des éléments communs, nous avons le caractère multiple de la résistance chez les deux auteurs et la capacité continue de résister. Chez Freud, il est possible de reconnaître une dimension au-delà de la résistance de l’adversaire élément de traitement – en particulier à partir du second dualisme pulsionnel. La résistance, en conséquence, échapperait à toute tentative de soumission dans le cadre de l’expérience psychanalytique. Par contre, en ce qui concerne les éléments de l’éloignement, nous savons que la discussion du pouvoir est extrêmement coûteuse à la pensée foucaldienne, alors que chez Freud elle n’est pas thématisée comme telle.
A Comparison of Different Autorefractors With Retinoscopy in Children
Authors: Oral Yesim , Gunaydin Nesrin , Ozgur Ozlen , Arsan Aysu Karatay , Oskan Sibel 
Published: September 2012

Purpose:
To compare the results of different refractive error measurement devices including table-mounted and hand-held autorefractors and videoretinoscopy with cycloplegic retinoscopy (CR) in children to evaluate the usability and reliability of these devices in measuring refractive errors.

Methods:
Two hundred eyes of 100 children underwent autorefraction using table-mounted autorefractor with and without cycloplegia and videoretinoscopy after cycloplegia. All results were compared statistically.

Results:
The mean spheric values (SV) and spherical equivalent values (SEV) of the non-cycloplegic table-mounted autorefractor were found to be significantly lower and those of the cycloplegic table-mounted autorefractor were found to be significantly higher than CR results. There was no statistically significant difference in terms of mean SV and SEV between the hand-held autorefractor and CR. Although the mean SV using videoretinoscopy were 0.15 diopters lower than CR, this difference was not significant. Comparing CR with the other refraction methods, all devices correlated with each other. Sensitivity in diagnosing myopia was low for all methods but sensitivity in diagnosing hyperopia and astigmatism was high for table-mounted and hand-held autorefractors. The other reliability parameters were found to be similar for all devices.

Conclusions:
Both videoretinoscopy and hand-held autorefractor can be used in both screening and examination for children as an alternative to CR and table-mounted autorefractor.
