RESUMEN

Plastics play a significant part in human life and the world we live in. The use of plastics results in detrimental effects on the natural world, which compels us to look for viable replacements. As a result of their enhanced capacity to biodegrade, bioplastics are becoming increasingly important materials. In recent years, there has been a rapid ascent in the utilization of biopolymers in various applications. The objective of this research is to investigate the impact that silica obtained from rice hull ash (RHA) and microcrystalline cellulose (MCC) obtained from groundnut husk have on the properties of bioplastic obtained from wheat gluten and fish scales. The usage of fish scales has been shown to have a positive effect on weight reduction and debasement rates. Microcrystalline cellulose (MCC) is utilized in a wide range of concentrations, and the influence of MCC on bioplastic is researched. The biodegradability tests of bioplastic revealed that the plastic lost 35% of its weight in just 14 days. The experiments that were done to evaluate the chemical stability and tensile strength of the bioplastic indicated that the MCC content has a significant effect in improving the characteristics of the material.

RESUMEN

In 2009, 'Don't forget the children' guideline recommended that all new HIV-positive patients attending adult HIV services should have any existing children identified and tested for HIV alongside a coherent documentation process. A retrospective case note review was performed on 173 HIV-positive women registered at the Royal South Hants adult HIV service until 31 January 2014. Data were assessed as a whole (n = 173) and, in addition, two comparator groups were formulated: (a) pre-guidelines (n = 108) and (b) post-guidelines (n = 65). Out of 80 children eligible for HIV testing, only 43 (54%) had clear documentation of a test result, and in the remaining 37 (46%), it was either not considered or not followed through. Documentation of need for testing increased significantly from 67% in pre-guideline group to 100% in the post-guideline group (p < 0.001). The median time from recognition of need to test to actual testing remained 24 months in both groups. Although this audit demonstrated improvement in identification of at-risk children and their testing, there is still need for improvement.

RESUMEN

Increasing screening frequency in men who have sex with men (MSM) engaging in high-risk behaviours can reduce prevalence of sexually transmitted infections (STIs). This evaluation investigated the impact of applying stricter screening guidelines for MSM on service workload and earlier STI diagnoses. A validated risk assessment tool (RAT) was distributed to MSM attending a level 3 sexual health service over three months. Australian screening guidelines were applied to the data to identify MSM requiring more frequent screening and data projected to the larger MSM population. The RAT identified a 2-5-fold increase in the number of STI and HIV screenings required based on six- and three-monthly screening intervals, respectively, in the MSM cohort. When screening intervals are reduced from three-monthly to six-monthly there is a potential loss of 66.7% of earlier HIV diagnoses. The use of RATs will increase workload in sexual health services, but potentially diagnose a large proportion of disease earlier.

RESUMEN

This study assesses the prevalence and correlates of pearly penile papules (PPP) in two non-genitourinary (GU) medicine male cohorts (<25 and >50 years). PPP were categorised in 188 university students (<25 years), based on self-examination, and 70 patients (>50 years), based on clinician examination. PPP were categorised from 1 to 4, based on increasing papule size and distribution. An anonymous questionnaire was used to identify associations with PPP prevalence. The prevalence of PPP was 38.3% in <25 years, and 11.4% in >50 years (P < 0.001). The prevalence of categories 3 and 4 PPP was 8.5% in <25 years, and 1.4% in >50 years (P < 0.05). In the younger age group, the prevalence of PPP was 26.5% in circumcised participants, and 42.4% in uncircumcised participants (P < 0.05), but was unrelated to either frequency of sexual intercourse or time since first sexual intercourse. In conclusion, PPP disappear with age, and any PPP in patients >50 years are less marked than those in patients <25 years. Patients should be advised accordingly. PPP are less prevalent in circumcised men. Patients could be advised to wear the foreskin rolled back - this may maximize exposure of the coronal area to normal abrasion, which may hasten PPP regression.

RESUMEN

The ability to control hospital-acquired infections is highly dependent upon control of cross-contamination from health-care workers to patients, and from one anatomical area of the patient to another anatomical area. Hand hygiene has been demonstrated to be an essential prerequisite in preventing cross-contamination. Wearing gloves does not afford complete protection against cross-contamination. Hand hygiene includes handwashing between patients, the use of alcohol-based skin cleansers and changing or removing gloves between examining different anatomical sites. There are no previously published audits regarding compliance to hand hygiene in genitourinary (GU) medicine clinics. A validated observation tool was employed in this audit. Doctors and nurses were observed in clinical practice. The adherence to hand hygiene protocols was overall poor. Doctors were more likely to adhere to protocols than nurses (83.3% vs. 66%). However, techniques of glove removal were universally satisfactory. Strategies for improvement in hand hygiene are suggested. These include performance feedback and use of posters.

RESUMEN

OBJECTIVES: To assess the public health consequence of patients electing not to be seen within 48 hours in a genitourinary medicine (GUM) clinic. METHODS: A 3-month retrospective case notes review was carried out for 310 new and re-book patients who chose to wait for more than 48 hours to be seen. RESULTS: Altogether, 10% (310/3110) of patients opted to be seen beyond 48 h. Their median wait was 6 days including weekends and 4 days excluding weekends. Demographic details did not vary except for the male to female ratio of 1:1.7 (1:1 in patients seen within 48 h). We found that no symptomatic patients or asymptomatic contacts of those with known sexually transmitted infections (STIs) reported sex with a new partner after booking their appointment. No patient reported sex with a recently treated partner who consequently required re-treatment and none suffered a complication of a STI. In addition, there were no cases of new HIV infection in this group and the rates of STIs were similar compared with patients seen within 48 hours of contacting the unit. CONCLUSIONS: Despite 10% of patients choosing to delay attendance beyond 48 h, no adverse public health outcomes were demonstrated.

RESUMEN

We present a 21-year-old woman with a short history of pelvic pain. The history was unremarkable apart from that of undergoing a surgical termination of pregnancy (TOP) some three-and-half years ago. Examination revealed a foreign body at the cervical os. Subsequent investigations revealed more foreign bodies within the cervical canal and uterine cavity, which were removed. Histologically these were found to be bones. Removal of the bone fragment initially discovered lead to an improvement of symptoms. Although the patient was treated for pelvic-inflammatory disease, no infective cause could be established. The condition of intrauterine retained fetal bones is recognized, but rare. Patients experiencing pelvic pain usually present sooner after TOP than did this patient. Although rare, it is an important condition to diagnose as it represents a treatable cause of infertility.
