ACAROSAN AND THE ACAREX TEST IN THE CONTROL OF HOUSE DUST MITE ALLERGENS IN THE HOME

House dust mites are believed to be major triggers for allergic disease in atopic individuals. As part of a programme controlling dietary and aero-allergen exposure in high-risk infants, an acaricidal foam and powder (Acarosan) was applied to bedroom and main living room carpets, as well as upholstered furniture, on four occasions in the first year of life. Dust was assayed for mite antigen (Der p1) and these results compared with the semi-quantitative assay of guanine content (Acarex Test). After nine months mean Der p1 levels had decreased by 70% in the treatment group. Proportionally, the greatest fall occurred in those items that had the highest initial mite antigen content. The Acarex score does show a correlation with Der p1 levels, but cannot replace antigen assay when accurate data is required. A chemical acaricide may help reduce house dust mite antigen levels, but is not by itself sufficient to reduce levels below that considered critical for sensitisation.     

Design of Complete Dentures by Adopting CAD Developed for Fixed Prostheses

The demand for complete dentures is expected to increase worldwide, but complete dentures are mainly designed and fabricated manually involving a broad series of clinical and laboratory procedures. Therefore, the quality of complete dentures largely depends on the skills of the dentist and technician, leading to difficulty in quality control. Computer‐aided design and manufacturing (CAD/CAM) has been used to design and fabricate various dental restorations including dental inlays, veneers, crowns, partial crowns, and fixed partial dentures (FPDs). It has been envisioned that the application of CAD/CAM technology could reduce intensive clinical/laboratory work for the fabrication of complete dentures; however, CAD/CAM is seldom used to fabricate complete dentures due to the lack of suitable CAD software to design virtual complete dentures although the CAM techniques are in a much advanced stage. Here we report the successful design of virtual complete dentures using CAD software of 3Shape Dental System 2012, which was developed for designing fixed prostheses instead of complete dentures. Our results demonstrated that complete dentures could be successfully designed by the combination of two modeling processes, single coping and full anatomical FPD, available in the 3Shape Dental System 2012.     

Depression and anxiety in amyotrophic lateral sclerosis: Correlations between the distress of patients and caregivers

Introduction: Depression and anxiety are common in amyotrophic lateral sclerosis (ALS) patients and caregivers. Methods: In this study we investigated 93 ALS patients and their 93 caregivers. Depression and anxiety were quantified by the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale, respectively. Results: Very strong correlations between depression and anxiety were found among patients and their caregivers. The severity of depression and anxiety of patients correlated moderately with that of their caregivers. No correlations were found between the severity of depression and anxiety and ALS Functional Rating Scale–Revised (ALSFRS‐R) score or for disease duration among patients and caregivers. However, severity of depression and anxiety in caregivers correlated with their age. Conclusions: Depression and anxiety in ALS patients and their caregivers were associated closely with each other but not with physical disability or disease duration in our Chinese population.

Multivisceral Resection in Colorectal Cancer: A Systematic Review

Background

The objective of this study was to critically evaluate current literature on outcomes following multivisceral resection (MVR) in colorectal cancer (CRC). Adequate surgical resection with clear margins is imperative in achieving long-term survival in colorectal cancer. Where there is adherence to or invasion of adjacent organs, (MVR) may be needed to achieve complete disease clearance.

Methods

A systematic review of MVR in CRC was performed. Pubmed/Medline and Cochrane databases were searched for English language articles from 1995 to 2012 using a predefined strategy. Retrieved abstracts were independently screened for relevance and data extracted from selected studies by 2 researchers. Results are reported as weighted means.

Results

Included were 22 studies comprising 1575 patients (87.0 % primary colorectal cancer; 13.0 % recurrent, 63.8 % rectal; 36.2 % colon). The most common organs resected were the bladder and reproductive organs. The perioperative mortality was 4.2 % with morbidity of 41.5 % (95 % CI, 40.8–42.2 %). The overall 5-year survival rate was 50.3 % (95 % CI, 49.9–50.8 %). Surgery for recurrence was associated with worse outcomes than primary tumors with 5-year survival 19.5 % (95 % CI, 17.8–21.1 %) for recurrent rectal cancer and primary rectal tumors 5-year overall survival 52.8 % (95 % CI, 52.0–53.8 %). R0 resection was the strongest factor associated with long-term survival.

Conclusions

Multivisceral resection provides the best possibility of long-term survival in locally advanced primary colorectal cancer in which a clear margin has been achieved.
