Age- and sex-associated changes in cerebral glucose metabolism in normal healthy subjects: statistical parametric mapping analysis of f-18 fluorodeoxyglucose brain positron emission tomography
Authors: Kim In-Ju , Kim Seong-Jang , Kim Yong-Ki 
Published: December 2009

Background: The age- and sex-associated changes of brain development are unclear and controversial. Several previous studies showed conflicting results of a specific pattern of cerebral glucose metabolism or no differences of cerebral glucose metabolism in association with normal aging process and sex. Purpose: To investigate the effects of age and sex on changes in cerebral glucose metabolism in healthy subjects using fluorine-18 fluorodeoxyglucose (F-18 FDG) brain positron emission tomography (PET) and statistical parametric mapping (SPM) analysis. Material and Methods: Seventy-eight healthy subjects (32 males, mean age 46.6±18.2 years; 46 females, mean age 40.6±19.8 years) underwent F-18 FDG brain PET. Using SPM, age- and sex-associated changes in cerebral glucose metabolism were investigated. Results: In males, a negative correlation existed in several gray matter areas, including the right temporopolar (Brodmann area [BA] 38), right orbitofrontal (BA 47), left orbitofrontal gyrus (BA 10), left dorsolateral frontal gyrus (BA 8), and left insula (BA 13) areas. A positive relationship existed in the left claustrum and left thalamus. In females, negative changes existed in the left caudate body, left temporopolar area (BA 38), right orbitofrontal gyri (BA 47 and BA 10), and right dorsolateral prefrontal cortex (BA 46). A positive association was demonstrated in the left subthalamic nucleus and the left superior frontal gyrus. In white matter, an age-associated decrease in FDG uptake in males was shown in the left insula, and increased FDG uptake was found in the left corpus callosum. The female group had an age-associated negative correlation of FDG uptake only in the right corpus callosum. Conclusion: Using SPM, we found not only similar areas of brain, but also sex-specific cerebral areas of age-associated changes of FDG uptake.

Sinus pericranii (SP) is a rare venous varix in an extracranial location connected to the intracranial venous system. The aim of this retrospective study was to report on 16 pediatric cases of SP with consideration of the preoperative evaluation of surgical risk.

Methods
The study population consisted of 10 patients who had undergone surgery for SP and 6 patients with concomitant craniosynostosis and SP. The mean age of the patients at presentation was 3.7 years. To identify characteristics of SP with high operative risk, 8 cases in this report and 11 previously reported cases of SP with sufficient information were categorized on the basis of the number and size of SP, the number and size of transcranial channels, the venous drainage type, and the amount of blood loss. Hemorrhage amounts were classified into 3 grades based on the description of intraoperative blood loss.

Results
Sinus pericranii not associated with craniosynostosis were resected without any postoperative morbidity. Sinus pericranii associated with craniosynostosis were preserved. After craniofacial reconstruction, 2 cases of SP with craniosynostosis regressed, completely in one patient and partially in another. These 2 patients with SP were confirmed to have compromised intracranial sinus before craniofacial reconstruction. Among a total of 19 patients, multiplicity or size (> 6 cm) of SP (p = 0.036) and multiplicity (> 3) or size (> 3 mm) of transcranial channels (p = 0.004) was associated with more severe hemorrhage grade. Sinus pericranii with peripheral venous drainage (drainer type) was not associated with hemorrhage grade after classification into 3 grades (p = 0.192). However, all 3 cases of SP with massive Grade 3 hemorrhage were the drainer type. Hemorrhage grade was correlated with the number of risk factors for SP (r = 0.793, p < 0.001).

Conclusions
Three risk factors of SP and the presence of compromised intracranial sinus are markers for highrisk SP. “Squeezed-out sinus syndrome” is suggested as a concept for SP associated with compromised intracranial sinus, mainly caused by craniosynostosis. Sinus pericranii in squeezed-out sinus syndrome probably serves as a crucial alternative to venous drainage of the brain with intracranial venous compromise. Conservative treatment for such patients with SP is recommended.

Radiosurgery is an important and well-accepted method in the management of brain metastases. Using conventional frame-based techniques, high lesional control rates are expected. The introduction of image-guided techniques allows for improved patient comfort and workflow. Some controversy exists as to the accuracy of imageguided techniques and consequently the impact they might have on control of brain metastases (as opposed to the level of control achieved with frame-based methods). The authors describe their initial 15-month experience with image-guided radiosurgery (IGRS) using Novalis with ExacTrac for management of brain metastases.

Methods
The authors reviewed the cases of brain metastasis treated by means of IGRS in their tertiary regional radiation oncology service over a 15-month period. During the study period 54 patients (median age 57.9 years) harboring 108 metastases were treated with IGRS. The median time from cancer diagnosis to development of brain metastasis was 12 months (range 0–144 months). The median tumor volume was 0.98 cm3 (range 0.03–19.07 cm3). The median prescribed dose was 18 Gy to the 80% isodose line (range 14–20 Gy). Lesions were followed with postradiosurgery MR imaging every 2–3 months following treatment.

Results
The median follow-up period was 9 months (range 0–20 months). Median actuarial survival was 8.6 months following IGRS. Eight patients with 18 lesions died within the first 2 months after the procedure, before scheduled follow-up imaging. Thus 90 lesions (in 46 patients) were followed up with imaging studies. Lesions that were unchanged or reduced in size were considered to be under control. The 6-month actuarial lesion control rate was 88%. Smaller lesions (< 1 cm3) had a statistically improved likelihood of complete imaging response (loss of all contrast-enhancement p = 0.01).

Conclusions
Image-guided radiosurgical treatment of brain metastases resulted in high rates of tumor control comparable to control rates reported for frame-based methods. High control rates were seen for small lesions in which spatial precision in dose delivery is critical. These data suggests that in regard to lesion control, IGRS using Novalis with ExacTrac is equivalent to frame-based radiosurgery methods.

While many studies have been published outlining morbidity following radiosurgical treatment of vestibular schwannomas, significant interpractitioner and institutional variability still exists. For this reason, the authors conducted a systematic review of the literature for non-audiofacial-related morbidity after the treatment of vestibular schwannoma with radiosurgery.

Methods
The authors performed a comprehensive search of the English-language literature to identify studies that published outcome data of patients undergoing radiosurgery treatment for vestibular schwannomas. In total, 254 articles were found that described more than 50,000 patients and were analyzed for satisfying the authors' inclusion criteria. Patients from these studies were then separated into 2 cohorts based on the marginal dose of radiation: ≤ 13 Gy and > 13 Gy. All tumors included in this study were < 25 mm in their largest diameter.

Results
A total of 63 articles met the criteria of the established search protocol, which combined for a total of 5631 patients. Patients receiving > 13 Gy were significantly more likely to develop trigeminal nerve neuropathy than those receiving < 13 Gy (p < 0.001). While we found no relationship between radiation dose and the rate of developing hydrocephalus (0.6% for both cohorts), patients with hydrocephalus who received doses > 13 Gy appeared to have a higher rate of symptomatic hydrocephalus requiring shunt treatment (96% [> 13 Gy] vs 56% [≤ 13 Gy], p < 0.001). The rates of vertigo or balance disturbance (1.1% [> 13 Gy] vs 1.8% [≤ 13 Gy], p = 0.001) and tinnitus (0.1% [> 13 Gy] vs 0.7% [≤ 13 Gy], p = 0.001) were significantly higher in the lower dose cohort than those in the higher dose cohort.

Conclusions
The results of our review of the literature provide a systematic summary of the published rates of nonaudiofacial morbidity following radiosurgery for vestibular schwannoma.

Objective.Associations between the use of micronutrient supplements (MS) and disease activity, quality of life (QOL), and healthcare resource utilization were studied in a Canadian population of patients with systemic lupus erythematosus (SLE).Methods.QOL was assessed by the Medical Outcomes Study 36-item Short Form. Healthcare resource utilization and disease activity/damage were determined.Results.Of the 259 subjects studied, 53% were MS users and 34% used only calcium/vitamin D. MS users had a higher Systemic Lupus International Collaborating Clinics score and utilized more healthcare resources. Disease activity and QOL were similar between MS users and nonusers.Conclusion.MS are frequently used by patients with SLE and are not associated with concomitant benefit on QOL. MS users utilized more healthcare resources.

QUANTITATIVE RESPONSES OF MALES OF LIMONIUS CALIFORNICUS (COLEOPTERA: ELATERIDAE) TO FEMALE SEX PHEROMONE
Authors: Lilly C. E. , McGinnis A. J. 
Published: December 2009

AbstractIn adult virgin females of the sugar beet wireworm, Limonius californicus (Mannerheim), the sex attractant (recently identified as valeric acid) is found primarily in the fifth and sixth abdominal segments. Ether extracts of virgin females and of females that had been mated for not more than 4 hours prior to death contained the highest concentration of the attractant. The concentration of attractant in mated females decreased as the post-copulatory interval increased. In the laboratory maximum sexual response was elicited from males exposed to as little as 0.008 female equivalent of attractant. Numerous thin-walled sensoria are present on the eight distal segments of the male antennae and apparently function as chemoreceptors. Response of males to the attractant was not affected by bilateral amputation of the five distal segments, decreased progressively with the amputation of segments 6 and 7, and was eliminated upon removal of segment 8. Males of L. californicus responded only to extracts of females of that species whereas males of Limonius canus (LeConte) responded to extracts of females of both species.
THE ESTABLISHMENT OF LOPHYROPLECTUS LUTEATOR (HYMENOPTERA: ICHNEUMONIDAE) ON NEODIPRION SERTIFER (HYMENOPTERA: DIPRIONIDAE) IN ONTARIO
Authors: Griffiths K. J. , Lyons L. A. 
Published: December 2009

AbstractLophyroplectus luteator (Thunb.), a European ichneumonid, was liberated in three Neodiprion sertifer-infested plantations in southern Ontario. Following one introduction in 1962, the parasite has survived 4 years and has spread at least 1.4 mites. Six per cent of the hosts collected within the plantation in 1966 produced adult parasites. Another smaller introduction in 1962 was unsuccessful. Following the third introduction, made in 1964, the parasite has survived 2 years and the attack level is now nearly 9 per cent.

THE LIFE HISTORY AND MORPHOLOGY OF ADELGES LARICIATUS (HOMOPTERA: PHYLLOXERIDAE)
Authors: Cumming Margaret E. P. 
Published: December 2009

AbstractChermes lariciatus was described by Patch from the gallicola migrans and further information on this form was given by Annand under the genus Adelges. The complete polymorphic cycle on spruce and larch is described here, with information about the life history, habits, seasonal development, and morphology. Fundatrices overwinter as nymphs below new buds of spruce on 1-year-old needle bases. Gallicolae develop in early summer within galls which are globular in shape and usually only partly surround the twigs. Sistentes overwinter as first-instar nymphs on larch buds, wedged among the bases of the needles or scales, with the heads up and the mouth parts inserted into the bud. The progredientes and sexuparae move to the new cones in early summer when there is a cone crop, but settle on the leaf buds when there is none. Sexuales nymphs on spruce remain under the parent sexuparae during development. A diagrammatic representation of the seasonal development and a description of the morphology of the first-instar nymph and adult of each form is given. A discussion concerning the validity of this and related species is included.

Published: December 2009

AbstractThe adult Arthropoda occurring in, on, or emerging from 2,660 sporophores of the bracket fungus Polyporus betulinus (Bull.) Fr., growing on dead birch, are listed. Collections were made in New Brunswick, Quebec, Ontario, and Manitoba. Two hundred and fifty-seven species of Arthropoda, mainly insects and mites, were recorded; over 49,000 specimens were examined. Old, twice-wintered sporophores produce more species and more individuals. In general, the fungus is rich in species but rarely produces sizable populations of any one species.

Authors: Reinhard H. J. 
Published: December 2009

AbstractThe tachinid genus Macromya (type, depressa R.-D.) as here considered includes five species of which three are described as new. All members are quite similar in external adult morphology as well as in biology. In the accompanying key to the currently known species, the distinctions are made chiefly on basic color differences. The center of maximum population for the genus occurs in the neotropics; its range however extends well within the southern limits of the nearctic region.

PRECOCIOUS TERMINATION OF “OBLIGATORY” DIAPAUSE IN FIELD-COLLECTED PUPAE OF ANTHERAEA POLYPHEMUS
Authors: Mansingh A. , Smallman B. N. 
Published: December 2009

AbstractAntheraea polyphemus Cramer pupae, collected in early August, were found to maintain adult development at room temperature and natural daylength of late August and early September. These pupae had almost no coldhardiness, and heavy mortality occurred in the group of pupae stored at 6 °C. On the other hand, the pupae of A. polyphemus collected in late September were in diapause and were perfectly coldhardy. The possible relationship between the date of pupation and the incidence of diapause, and its significance as a natural mortality factor, is discussed.
ON THE TWO SPECIES OF BRUCHIDIUS (COLEOPTERA: BRUCHIDAE) ESTABLISHED IN NORTH AMERICA
Authors: Bottimer L. J. 
Published: December 2009

AbstractThe European Bruchidius ater (Marsh.), first discovered in Massachusetts in 1918, and later in Virginia, is here recorded from Rochester, N.Y. In addition to Cytisus scoparius (L.) Link, its known host in the United States, the insect was reared from seeds of Petteria ramentacea (Sieber) Presl and Laburnum alpinum Bercht. and Presl at the New York locality. All three plants are introductions from Europe. Bruchidius unicolor (Ol.) was recognized in 1965 when it was discovered in British Columbia breeding in the seed pods of Onobrychis viciaefolia Scop. A single specimen, collected in Nicola, B.C., in 1922, indicates that the insect has been present in southwestern Canada for a considerable time.
THE LIFE HISTORY OF IPS CALLIGRAPHUS (COLEOPTERA: SCOLYTIDAE) WITH NOTES ON ITS BIOLOGY IN CALIFORNIA
Authors: Wood D. L. , Stark R. W. 
Published: December 2009

AbstractIps calligraphus (Germar) is distributed continentally throughout North America, including Guatemala and British Honduras. It has been collected on only rare occasions in California, primarily in the central Sierra Nevada Mountains. Four generations were observed during 1961 and 1962, and average summer development required about 40 days. All stages except the egg were observed in the winter. The unique gallery system exhibits four to six egg galleries, which range in length from 25.4 to 38.1 cm, and radiate characteristically from a large, irregular, nuptial chamber excavated by the male. At Grass Valley, Cal., this bark beetle was observed breeding predominantly in the thick-barked portions of the lower bole. Its galleries are often intermixed with those of Dendroctonus brevicomis LeConte, I. confusus LeConte, I. latidens LeConte, and Melanophila californica Van Dyke in ponderosa pine. I. confusus was the most abundant species of Ips in all localities where I. calligraphus was found.
COMPARATIVE STUDIES ON THE BEHAVIOUR OF THREE SPECIES OF ANTS (HYMENOPTERA: FORMICIDAE): I. PREY FINDING, CAPTURE, AND TRANSPORT
Authors: Ayre G. L. 
Published: December 2009

AbstractMethods of finding, capturing, and transporting prey by the ants Formica obscuriventris Mayr, Myrmica americana Weber, and Crematogaster lineolata (Say) were studied under laboratory conditions. Each species found its prey by random searching but once the prey was attacked by one ant a definite attraction was created for other ants in the immediate area of attack. C. lineolata and M. americana workers were also recruited by means of a trail laid to the nest. The number of ants attacking each prey varied directly with the size and general resistance offered by the prey. The worker efficiency in prey transport by F. obscuriventris and M. americana varied inversely with the number of workers involved. C. lineolata did not attempt to transport the prey but fed upon it where captured.

LIFE HISTORY AND HABITS OF RHABDOPHAGA SP. (DIPTERA: CECIDOMYIIDAE), A GALL MIDGE ATTACKING WILLOW IN MICHIGAN
Authors: Wilson Louis F. 
Published: December 2009

AbstractThe taxonomic status of Rhabdophaga sp. cannot be determined until a complete revision of the genus occurs. Rhabdophaga sp. on Salix discolor Mühl. is univoltine in Michigan. Adults emerge in mid-April, and shortly afterward deposit numerous eggs on the setaceous undersurface of emerging willow leaves; larval eclosion occurs between 1 and 2 weeks later. Head capsule measurements reveal three larval instars. The first-instar larva bores into the stem until it reaches the pith. Gall development begins about mid-June shortly after the second instar appears. The third-instar larva overwinters in the gall and the pupa appears in early April. The prolate gall is found on the proximal ends of young willow shoots; heavily galled shoots usually die.
LIFE HISTORY AND HABITS OF THE WILLOW BEAKED GALL MIDGE, MAYETIOLA RIGIDAE (DIPTERA: CECIDOMYIIDAE), IN MICHIGAN
Authors: Wilson Louis F. 
Published: December 2009

AbstractThe willow beaked gall midge, Mayetiola rigidae (Osten Sacken), is univoltine in Michigan. Adults emerge from bud galls on Salix discolor Mühl. and other willows on mornings of warm days in early April. Eggs are laid singly on or near the buds of the host. Head capsule measurements indicate three larval instars. The last two instars each possess a spatula. The first-instar larva emerges in late April and penetrates the soft bud tissues. The gall begins to develop at the beginning of the second instar in mid-May. The third instar appears in early July and continues to enlarge the gall until fall. Prior to overwintering, the larva lines the inner chamber of the gall with silk and constructs one to seven silken septa across the passageway. Pupation occurs in mid-March. The gall deforms the stem and occasionally a galled branch dies or breaks off.
