Abstract
PURPOSE To provide real-life data on azole treatment outcomes and the role of surgery in the current management of invasive fungal rhinosinusitis complicated by orbitocranial fungal infection (OCFI). METHODS Data was collected retrospectively from a chart review from four participating centers and a systematic literature review. The study group included patients with OCFI treated with azole antifungals. The control cases were treated with other antifungal agents. The cranial and orbital involvement degree was staged based on the imaging. The extent of the surgical resection was also classified to allow for inter-group comparison. RESULTS There were 125 patients in the azole-treated group and 153 in the control group. Among the patients with OCFI cranial extension, 23% were operated on in the azole-treated group and 18% in the control group. However, meninges and brain resection were performed only in the controls (11% of patients) and never in the azole antifungals group. Orbital involvement required surgery in 26% of azole-treated cases and 39% of controls. Despite a more aggressive cranial involvement, azole-treated patients' mortality was significantly lower than in controls, with an OCFI-specific mortality rate of 21% vs. 52%. A similar, though not statistically significant, trend was found for the extent of the orbital disease and surgery. CONCLUSION Despite less aggressive surgical intervention for cranial involvement, OCFI patients treated with azoles had a higher survival rate. This finding suggests we may improve morbidity with a more conservative surgical approach in conjunction with azole treatment. The same trend is emerging for orbital involvement.

Abstract
OBJECTIVE The transnasal endoscopic approach may provide better visualisation and a safer approach to the orbital apex. This study presents a case series of orbital apex lesions managed by this approach. METHOD This study was an eight-year retrospective analysis of seven patients who were operated on for orbital apex lesions in two tertiary medical centres. RESULTS Complete tumour removal was performed in three patients and partial removal was performed in four patients. Visual acuity improved in three patients, remained stable in one patient and decreased in the other two patients. The visual field improved in four patients and did not change in two patients. Complications included worse vision and visual fields in 28.6 per cent of patients and late enophthalmos (of -1.25 ± 4.6 mm) in 2 patients. CONCLUSION The transnasal approach to orbital apex lesions in selected cases may provide a rational alternative to transorbital surgery. Complete tumour removal should be weighed against the risk of damage to the optic nerve.

Abstract
OBJECTIVES Noise-induced hearing loss (NIHL) may result from occupational noise exposures and is considered as an 'Occupational Disease'; therefore, it is compensable. To verify the existence and severity of the work-related hearing loss, there is a need of an objective, reliable auditory measure in cases of arbitration of financial disputes to resolve any medicolegal aspects. The objective of the study was to compare between the ABR and ASSR for predicting the behavioural threshold in subjects with normal hearing or NIHL. DESIGN The study included 82 subjects regularly exposed to high levels of occupational noise, with normal hearing and NIHL. ABR to clicks and to tone bursts were recorded followed by multiple-frequency ASSR. Physiological and behavioural thresholds were compared for specific frequencies (1000, 2000 Hz) and average of high-frequency range (2000 and 4000 Hz). In addition, Pearson correlations and the specificity and sensitivity of each measure were also calculated using receiver operating characteristic (ROC) curves. RESULTS In the NIHL group, there was a significantly smaller difference between the behavioural threshold and click-ABR than the ASSR in high-frequency range. Pearson correlations were significantly higher for click-ABR. Analysis of specific frequencies yielded a smaller difference between behavioural and ASSR than tone-burst-ABR thresholds, with a slightly better correlation for ASSR than tone-burst-ABR. Higher sensitivity but lower specificity was suggested for ASSR than ABR. CONCLUSIONS ASSR is associated with high-frequency specificity, shorter test sessions and good correlations with behavioural thresholds, making it a potentially better measure than ABR for predicting audiograms in subjects with NIHL. These findings have diagnostic implications, especially in cases of workers' compensation when subjects may be uncooperative.

Abstract
A single truncated chromosome fragment (TCF) in diploid cells undergoes frequent ectopic recombination during meiosis between markers located near the ends of the fragment. Tetrads produced by diploids with a single TCF show frequent loss of one of the two markers. This marker loss could result either from recombination of the TCF with one of the two copies of the chromosome from which it was derived or from ectopic recombination between the ends of the TCF. The former would result in shortening of a normal chromosome and lethality in one of the four spores. The high frequency of marker loss in tetrads with four viable spores supports recombination between the TCF ends as the main source of marker loss. Most of the spore colonies that display TCF marker loss contained a TCF with the same marker on both ends. Deletion of most of the pBR322 sequences distal to the marker at one of the subtelomeric regions of the TCF did not reduce the overall frequency of recombination between the ends, but affected the loss of one marker significantly more than the other. We suggest that the mechanism by which the duplication of one end marker and loss of the other occurs is based on association and recombination between the ends of the TCF.

Abstract
BACKGROUND When Saccharomyces cerevisiae cells that have begun meiosis are transferred to mitotic growth conditions ('return-to-growth', RTG), they can complete recombination at high meiotic frequencies, but undergo mitotic cell division and remain diploid. It was not known how meiotic recombination intermediates are repaired following RTG. Using molecular and cytological methods, we investigated whether the usual meiotic apparatus could repair meiotically induced DSBs during RTG, or whether other mechanisms are invoked when the developmental context changes. RESULTS Upon RTG, the rapid disappearance of meiotic features--double-strand breaks in DNA (DSBs), synaptonemal complex (SC), and SC related structures-was striking. In wild-type diploids, the repair of meiotic DSBs during RTG was quick and efficient, resulting in homologous recombination. Kinetic analysis of double-strand breakage and recombination indicated that meiotic DSB formation precedes the commitment to meiotic levels of recombination. DSBs were repaired in RTG in dmc1, but not rad51 mutants, hence repair did not occur by the usual meiotic mechanism which requires the Dmc1 gene product. In haploids, DSBs were also repaired quickly and efficiently upon RTG, showing that DSB repair did not require the presence of a homologous chromosome. In all strains examined, SC and related structures were not required for DSB repair or recombination following RTG. CONCLUSIONS At least two pathways of DSB repair, which differ from the primary meiotic pathway(s), can occur during RTG: One involving interhomologue recombination, and another involving sister-chromatid exchange. DSB formation precedes commitment to recombination. SC elements appear to prevent sister chromatid exchange in meiosis.

Abstract
Whether restoration takes place in the visual cortex of neonates was physiologically studied in cortical cells of cats following their deafferentation. Deafferentation was performed by a parasagittal incision made in the visual cortex, separating the medial part of it from the thalamocortical and other visual fibers. Responsiveness (percentage of responsive cells) in the middle zone (the middle sector along the cortical incision) of the deafferented region was 82.5%, compared with 91.7% in the afferented (lateral to the incision) region (p = 0.5). In comparison, the responsiveness level was 32.3 and 81.3% (p < 0.05) in the respective zones of the similarly deafferented adult controls. The ocular dominance distribution and binocularity were almost normal in the deafferented region of the neonatally operated cats, whereas binocularity was remarkably diminished in the adult controls. Recovery was also found in the specificity of the cells to orientation and direction in the neonatally operated cats, but not in the adult-operated cats. Thus, functional reorganization of the columnar organizations takes place in the neonatally deafferented but not in the adult-operated cats.

Abstract
We have studied the physiological properties of cells (N = 822) in visual cortex area 17 of seven adult cats transplanted with visual cortex xenografts from fetal (E15-E17) rats. The transplants were assumed to induce recovery of adjacent neurons partially deafferented from visual input. The control group (eight cats, 564 cells) had just analogous sectioning in the cortex. The level of activity found, following visual stimulation, in the deafferented cortical region (medially to the graft) was 48.6% compared to the result (34.5%) obtained in the control cats, indicating the preservation of visual responsiveness. Furthermore, no disturbance could be found in the ocular dominance distribution or binocularity (64.4%) of the cells in the grafted region compared to those in the control cats, indicating preservation of the columnar organization. The deafferented cells in the grafted cortex thus demonstrated the absence of adverse immunological reaction there due to the presence of the xenogeneic tissue, indicating that the visual cortex is immunologically privileged.
