Prosthetic Rehabilitation of Postsurgical Nasomaxillary Hypoplasia for a Patient Following Reconstructive Surgery: A Clinical Report

Repairs of the cleft nose, lip, and palatal deformity remain challenging endeavors for reconstructive surgeons. Postsurgical nasomaxillary hypoplasia is a common finding in patients with extensive clefts. This complex deformity has a pronounced impact on the social behavior and self image of the subject. Esthetic and functional rehabilitation of this postsurgical defect is scarcely reported in the literature. Support in the form of prostheses or stents to prevent tissue collapse is usually required in these patients following surgery. This clinical case presentation discusses the fabrication of an internal nasal stent for a cleft nose, lip, and palate patient following surgical reconstruction. Two prostheses using two prosthetic materials (Polymethyl methacrylate, flexible resin) were prepared to compare their efficacy. The final prostheses improved the patient's appearance, making the postsurgical defect less conspicuous.     

Hypertension in dialysis and kidney transplant patients

For the first time, the Canadian Hypertension Education Program has studied the evidence supporting blood pressure control in people requiring renal replacement therapy for end-stage kidney disease, including those on dialysis and with renal transplants. According to the Canadian Organ Replacement Registry’s 2008 annual report, there were an estimated 33,832 people with end-stage renal disease in Canada at the end of 2006, an increase of 69.7% since 1997. Of these, 20,465 were on dialysis and 13,367 were living with a functioning kidney transplant. Thus, it is becoming more likely that primary care practitioners will be helping to care for these complex patients. With the lack of large controlled clinical trials, the consensus recommendation based on interpretation of the existing literature is that blood pressure should be lowered to below 140/90 mmHg in hypertensive patients on renal replacement therapy and to below 130/80 mmHg for renal transplant patients with diabetes or chronic kidney disease.     

Adolescents with type 1 diabetes and risky behaviour

Aim: The aim of the student is to assess whether adolescents with type 1 diabetes mellitus (T1DM) in Italy differ from their healthy peers in regard to risky behaviour. Methods: Data were collected from 215 patients, aged 14 ± 2 years with a mean disease duration of 7 ± 5 years. The control group was comprised of 464 healthy adolescents recruited among high school students. Each patient completed an anonymous confidential questionnaire to determine the prevalence of sexual behaviour, alcohol and tobacco consumption, illicit drug use, and, among patients with diabetes and frequency of mismanagement related to diabetes care. Results: Compared with controls, subjects with diabetes showed a similar rate of sexual intercourse among males and lower rates among females (34.8% vs 35.5%, p NS and 29.4% vs 41.4%, p < 0.05, respectively). Males in the diabetes group reported a higher rate of tobacco use, whereas females showed similar or higher rates of use for every illicit drug studied. Among patients with diabetes, those who are engaged in risky behaviour showed a higher rate of treatment mismanagement (76% vs 34%, p < 0.01). Conclusion: Adolescents with T1DM are as likely as their healthy peers to engage in risky behaviour, indicating the potential benefit of anticipatory guidance concerning glycaemic control and increased risk of acute and chronic complications.     

A novel rapid and effective donor arm disinfection method

BACKGROUND: The aim of the study was to derive a donor arm disinfection technique that was rapid, but with a disinfection efficacy equivalent to a previous "best-practice" technique. This method consisted of a two-stage procedure with an initial application of 70% isopropyl alcohol and then 2% tincture of iodine (IATI). The total time for the IATI method was 2 minutes in duration. A rapid technique (1 min in duration) was needed to obviate potential problems due to increased donor waiting time, had the IATI method been implemented at blood donation sessions.
STUDY DESIGN AND METHODS: A direct swabbing and plating technique was used to enumerate bacteria present before and after disinfection. In total, seven methods were evaluated.
RESULTS: The chlorhexidine/alcohol applicator (CAA) disinfection device containing 1.5 mL of 2% chlorhexidine gluconate and 70% isopropyl alcohol (99.91% reduction; confidence limits, 99.55%, 99.98%) was shown to have equivalent disinfection efficacy as the IATI method (99.89% reduction; confidence limits, 99.36%, 99.98%; p = 0.86). Procedural time for the 1.5-mL CAA method was 1 minute thereby avoiding potential problems of increased donor waiting time, inherent in the IATI 2-minute procedure at blood donation sessions.
CONCLUSIONS: The 1.5-mL CAA disinfection method offers blood services a rapid and effective donor arm disinfection procedure. In 2006, the 1.5-mL CAA procedure was implemented throughout the entire English blood service for all donations.     

Circulating Levels of High Molecular Weight (HMW) Adiponectin and Total Adiponectin in Relation to Fat Distribution,Oxidative Stress and Inflammation in Asian Indians

Aim: To look at the association of total and high molecular weight (HMW) adiponectin with markers of fat distribution, oxidative stress and inflammation in Asian Indians. Methods: A total of 120 subjects were chosen randomly from Chennai Urban Rural Epidemiological Study. Fasting HMW adiponectin levels, TNF-alpha and oxidized LDL were measured using ELISA. High sensitivity C reactive protein (hsCRP) was measured by a high sensitive nephelometric assay. Lipid peroxidation was measured by Tbars assay and protein carbonyl content was assessed by DNPH assay. Visceral and subcutaneous fat areas were assessed by computed tomography (CT) scan.When stratified based on the tertiles of visceral fat, the levels of total (p = 0.03) and HMW adiponectin (p = 0.007) were highest in the first tertile followed by tertiles 2 and 3 whereas in tertiles of subcutaneous fat, there was no such trend. With increasing tertiles of Tbars, the levels of total (p = 0.03) and HMW adiponectin decreased (p = 0.002). The levels of HMW (p < 0.001) but not total adiponectin was also found to decrease with increasing tertiles of Protein carbonyl content. The levels of Total (p = 0.02) and HMW adiponectin (p = 0.004) were highest in the first tertile of oxidized LDL followed by tertile 2 and tertile 3. With increasing tertiles of TNF-alpha total (p = 0.01) and HMW adiponectin (p = 0.004) was found to decrease. With increasing tertiles of hs-CRP, Total (p = 0.005) and HMWadiponectin (p = 0.007)was found to decrease. Conclusion: Oxidative stress markers, visceral but not subcutaneous fat and inflammation are associated with total and HMW adiponectin levles in Asian Indians.     

Oligosaccharides in human milk during different phases of lactation

Twenty-one oligosaccharides of human milk were quantified by high-performance anion-exchange chromatography. Milk samples were collected from 18 mothers during the first 3 mo of lactation. The data show that the highest amount of all oligosaccharides is present at day 4 postpartum (20 g l⁻¹) and then decreases by about 20% at day 30 of lactation. The protective role played by these substances against different infectious agents, in different organs and systems of the breastfed baby, is emphasized.     

The coeliac iceberg in Italy. A multicentre antigliadin antibodies screening for coeliac disease in school-age subjects

Background : Recent studies suggest that coeliac disease (CD) is one of the commonest, life-long disorders in Italy. The aims of this multicentre work were: (a) to establish the prevalence of CD on a nationwide basis; and (b) to characterize the CD clinical spectrum in Italy. Patients and methods : Fifteen centres screened 17201 students aged 6–15 years (68.6% of the eligible population) by the combined determination of serum IgG- and IgA-antigliadin antibody (AGA) test; 1289 (7.5%) were IgG and/or IgA-AGA positive and were recalled for the second-level investigation; 111 of them met the criteria for the intestinal biopsy: IgA-AGA positivity and/or AEA positivity or IgG-AGA positivity plus serum IgA deficiency. Results : Intestinal biopsy was performed on 98 of the 111 subjects. CD was diagnosed in 82 subjects (75 biopsy proven, 7 not biopsied but with associated AGA and AEA positivity). Most of the screening-detected coeliac patients showed low-grade intensity illness often associated with decreased psychophysical well-being. There were two AEA negative cases with associated CD and IgA deficiency. The prevalence of undiagnosed CD was 4.77 × 1000 (95% CI 3.79–5.91), 1 in 210 subjects. The overall prevalence of CD, including known CD cases, was 5.44 × 1000 (95% CI 4.57–6.44), 1 in 184 subjects. The ratio of known to undiagnosed CD cases was 1 in 7. Conclusions : These findings confirm that, in Italy, CD is one of the most common chronic disorders showing a wide and heterogeneous clinical spectrum. Most CD cases remain undiagnosed unless actively searched.
