Abstract
BACKGROUND Microneedling (MN) and microcoring (MCT) are both methods used for percutaneous collagen induction. This minimally invasive technique involves creating controlled damage in cutaneous tissue to induce neocollagenesis and neoelastogenesis. MN utilizes solid microneedles and is commonly combined with radiofrequency (RF) to add thermal energy, while MCT involves hollow microneedles capable of removing excess tissue without inducing scar formation. AIMS The purpose of this review was to summarize recent literature for MN and MCT, with the goal of assisting clinical decision making regarding the use of these technologies. METHODS PubMed search was conducted for relevant articles published within the last 10 years. Scoping literature review was then performed with pertinent findings reported. RESULTS Existing literature investigating MCT is sparse. Limited data on in vivo, human effects of this technology exist. Two out of 14 studies in this review pertained to MCT. CONCLUSION Additional high-powered clinical studies are needed to guide future cosmetic treatments with MN and MCT.

Abstract
Pemphigus foliaceus (PF) is an autoimmune blistering disease limited to the superficial skin without mucosal involvement. It is clinically, histologically, and immunopathologically distinct from pemphigus vulgaris (PV). As data on pediatric PF is often merged with data on both pediatric and adult PV patients, isolating clinical outcomes in pediatric PF is not always possible. Therefore, the authors of this review analyzed clinical outcomes following therapy in pediatric PF patients only. A search of databases resulted in 33 pediatric patients with PF. In total, 19 (57.6%) patients were treated with conventional immunosuppressive therapies (CISTs), which consisted of systemic corticosteroids and multiple immunosuppressive agents (ISAs). Further, 14 (42.4%) patients were treated with biologic agents, predominantly rituximab (RTX). The mean age of those treated with biologics was 12.8 years (range = 0.88-18 years) compared to 8.9 years (range = 0.92-15 years) of those treated with CIST (p = 0.01). Treatment with biologics was initiated significantly longer after the diagnosis of PF when compared to patients treated with CIST (p = 0.003). RTX was used in all patients who received biologic therapy. Two (6%) patients also received intravenous immunoglobulin. When clinical outcomes were compared between CIST and biologic therapy, rates of clinical remission, partial remission, and relapse, were not statistically significantly different between groups. When RTX was used, rates of relapse and adverse events were higher in those treated with the lymphoma protocol (375 mg/m2 once weekly for four weeks) compared to those treated with the rheumatoid arthritis protocol (two doses of 1,000 mg two weeks apart) (p < 0.0001). The incidence of adverse events was statistically significantly higher in patients treated with CIST when compared to RTX (p = 0.003). These included both physical and psychological changes. The infection rate after treatment with RTX was 7.1%. These outcomes occurred during a follow-up of 12.5 months (range = 1-36 months) in the CIST group and 20.5 months (range = 6-67 months) in the biologic therapy group. The difference in the follow-up period was not statistically significant. The literature suggests that biologics are superior to CIST in treating pemphigus patients. The results of this review suggest similar responses to therapy in pediatric PF patients treated with biologics compared to CIST. This may have been due to a limited duration of follow-up and a lack of detailed treatment outcomes in pediatric PF patients. The data in this review strongly suggests that specific treatment protocols need to be developed and implemented for pediatric PF patients. These patients are at a critical phase in life where PF therapy can influence or affect physical growth, hormonal changes, psychosocial development, and essential education.

Abstract
A multilaboratory study was conducted to compare the automated BAX® system and the standard cultural methods for detection of Listeria monocytogenes in foods. Six food types (frankfurters, soft cheese, smoked salmon, raw, ground beef, fresh radishes, and frozen peas) were analyzed by each method. For each food type, 3 inoculation levels were tested: high (average of 2 CFU/g), low (average of 0.2 CFU/g) and uninoculated controls. A total of 25 laboratories representing government and industry participated. Of the 2335 samples analyzed, 1109 were positive by the BAX system and 1115 were positive by the standard method. A Chi square analysis of each of the 6 food types, at the 3 inoculation levels tested, was performed. For all foods, except radishes, the BAX system performed as well as or better than the standard reference methods based on the Chi square results.

Abstract
Abstract
A collaborative study was conducted to validate new enrichment methods for the TECRA Listeria Visual Immunoassay (TLVIA). These new methods incorporate a newly formulated medium, TECRA Listeria Enrichment Broth, which does not contain the highly toxic antifungal agent, cycloheximide. The new procedures will provide an alternative to the enrichment procedures described in AOAC Method 995.22. Three food types (raw ground beef, lettuce, and ice cream) were analyzed in the United States, and 2 food types (cooked turkey and cooked fish fillets) were analyzed in Australasia. Thirty collaborators participated in the study, 16 in Australasia and 14 in the United States. With the exception of one batch of ground beef, comparison of the proportion of positive test portions (p ≥ 0.05) showed no significant difference between the TLVIA and the reference method for the 5 foods at 3 inoculation levels. For the one batch of naturally contaminated raw ground beef, the TLVIA gave significantly more confirmed positive results than the reference method.

Abstract
A rehydratable dry-film plating method for Staphylococcus aureusin foods, the 3M™ Petrifilm™ Rapid S. aureus Count Plate method, was compared with AOAC® Official MethodSM 975.55 (Staphylococcus aureus in Foods). Nine foods—instant nonfat dried milk, dry seasoned vegetable coating, frozen hash browns, frozen cooked chicken patty, frozen ground raw pork, shredded cheddar cheese, fresh green beans, pasta filled with beef and cheese, and egg custard—were analyzed for S. aureus by 13 collaborating laboratories. For each food tested, the collaborators received 8 blind test samples consisting of a control sample and 3 levels of inoculated test sample, each in duplicate. The mean log counts for the methods were comparable for pasta filled with beef and cheese; frozen hash browns; cooked chicken patty; egg custard; frozen ground raw pork; and instant nonfat dried milk. The repeatability and reproducibility variances of the Petrifilm Rapid S. aureus Count Plate method were similar to those of the standard method.

Abstract
The purpose of this study was to investigate the variables that affect psychological general well-being (quality of life) in patients with cochlear implants (CIs). The study sample consists of 96 adult patients with a CI, aged 24 86 years (Mean = 61.8 yrs; SD = 15.3 yrs). 48 were patients from the Sahlgrenska University Hospital in Sweden and 48 were patients from the University of Florida, USA. The Psychological General Well-being Index and the International Outcome Inventory-Cochlear implants were used in collecting data. Possible independent variables were socioeconomic factors such as age, gender, nationality, living arrangement, education, and social support; as well as length of time since implantation, age when hearing loss became a problem, and subjective benefit of the CI. A stepwise multiple regression analysis showed that 49% of the variance was explained by attitudes from others, restricted social participation, perceived social support and age.

Abstract
A series of 7-alkylidenecephalosporins and 7-vinylidenecephalosporins, as their benzhydryl esters, have been tested as inhibitors of both porcine pancreatic elastase and human leukocyte elastase. Selected 7-alkylidenecephalosporin esters are found to be potent inhibitors of HLE. One category of new inhibitors is the 7-(haloalkylidene)cephalosporins. In contrast to previously reported cephalosporin-based elastase inhibitors, these haloalkylidene cephems show optimum inhibitory activity as sulfides, rather than as sulfones. They are efficient and irreversible inhibitors. A second class of active compounds is represented by the benzhydryl ester 7-(cyanomethylidene)cephalosporin sulfone. In contrast to the activity of these new inhibitors, the benzhydryl ester of the mechanism-based beta-lactamase inhibitor, 7-[(2'-pyridyl)methylidene]-cephalosporin sulfone showed little inhibitory activity as an elastase inhibitor. 7-Vinylidenecephalosporins were also relatively poor inhibitors, although the terminally unsubstituted allene sulfide showed activity as an inhibitor of PPE. A modeling analysis suggests the 7-alkylidene substituents can be readily accommodated in the S1 pocket. A potential mechanism of inhibition is proposed.

Abstract
BACKGROUND In patients with chronic pancreatitis, surgery is indicated for the management of intractable pain or for the treatment of complications. METHODS Sixty-three consecutive patients (49 men and 14 women of median age 40 (range 20-72) years) who had undergone surgery over an 8-year interval for chronic pancreatitis were studied. The mortality and morbidity rates associated with surgery were assessed and quality of life was reviewed based on relief of symptoms, analgesic use, employment and long-term sequelae. RESULTS Forty-four patients (70 per cent) had alcoholic chronic pancreatitis. In 60 patients the principal indication for surgery was intractable pain. Eighteen patients had a duodenum-preserving resection of the pancreatic head (Beger operation); the other surgical procedures were Whipple resection (15), left-sided resection (13), total pancreatectomy (seven), pseudocystjejunostomy (five), pancreaticojejunostomy (one) and bypass procedures (four). The median inpatient stay was 12 days; 23 patients had postoperative complications including one death (2 per cent). There was improved pain control (P < 0.001), a reduction in opiate analgesia use, increase in percentage weight gain (P < 0.01 at 2 years) and return to employment following surgery. Although there was an increase in diabetes mellitus and need for enzyme supplementation these were easily controlled. CONCLUSION Surgery is an effective treatment in carefully selected patients with chronic pancreatitis but must be tailored to the pattern of disease in each individual.

Abstract
Family physician Cynthia Carver wasn't heartened by the CMA's "last-minute retreat" from a call to pursue privatization of health care. During its August annual meeting, the association not only supported a strong, publicly funded health care system but also passed a number of resolutions related to the private sector and the appropriate role for regulated private medical insurance in Canada. Carver proposes that the energy being expended on schemes to delist, privatize, define core services and design payment schemes should instead be applied to improving the existing system.

Abstract
Preliminary data from a randomized study of the effectiveness of combined marital therapy and antidepressant medication in the treatment of dysthymic married women is presented. The study compares doxepin with placebo, and a marital therapy designed to enhance intimacy through facilitating self-disclosure between spouses with a more supportive and educational therapeutic approach. After ten weeks of combined treatment, the dysthymic women show statistically significant improvement on all the depression measures as well as on the intimacy scale. A trend is developing for greater reduction of depressive symptomatology in the group treated with self-disclosure. The evidence appears to suggest the possibility that the presence of a patient's husband as a supportive figure may of itself be a potent therapeutic manoeuvre in the treatment of dysthymic women.

Abstract
A review of recent studies of family interaction as a causal factor in the development of schizophrenia suggests a paucity of evidence supporting this point of view. However, research has suggested family variables may influence the course and outcome of schizophrenia. The impact of schizophrenia on the family has recently received more attention. Some research has identified differences between families of schizophrenics and the families of other diagnostic groups and controls. Whether these studies are beginning to influence the theory and practice of family therapy is discussed. Recent studies suggest the combination of long-acting medication and 'psychosocial' interventions may reduce the relapse rate of schizophrenia in the short term. This research suggests that family therapists must re-evaluate their role in the management of schizophrenia.
