Sensation and sexual arousal in circumcised and uncircumcised men

IntroductionResearch, theory, and popular belief all suggest that penile sensation is greater in the uncircumcised as compared with the circumcised man. However, research involving direct measurement of penile sensation has been undertaken only in sexually functional and dysfunctional groups, and as a correlate of sexual behavior. There are no reports of penile sensation in sexually aroused subjects, and it is not known how arousal affects sensation. In principle, this should be more closely related to actual sexual function.AimThis study therefore compared genital and nongenital sensation as a function of sexual arousal in circumcised and uncircumcised men.MethodsTwenty uncircumcised men and an equal number of age-matched circumcised participants underwent genital and nongenital sensory testing at baseline and in response to erotic and control stimulus films. Touch and pain thresholds were assessed on the penile shaft, the glans penis, and the volar surface of the forearm. Sexual arousal was assessed via thermal imaging of the penis.ResultsIn response to the erotic stimulus, both groups evidenced a significant increase in penile temperature, which correlated highly with subjective reports of sexual arousal. Uncircumcised men had significantly lower penile temperature than circumcised men, and evidenced a larger increase in penile temperature with sexual arousal. No differences in genital sensitivity were found between the uncircumcised and circumcised groups. Uncircumcised men were less sensitive to touch on the forearm than circumcised men. A decrease in overall touch sensitivity was observed in both groups with exposure to the erotic film as compared with either baseline or control stimulus film conditions. No significant effect was found for pain sensitivity.ConclusionThese results do not support the hypothesized penile sensory differences associated with circumcision. However, group differences in penile temperature and sexual response were found. Payne K, Thaler L, Kukkonen T, Carrier S, and Binik Y.

Nursing documentation in nursing homes--state-of-the-art and implications for quality improvement

This study was designed to gain information on the quality of nursing care based on the comments in nursing records. The specific aims of the study were to find out if the patients' (i) individual needs are assessed, the goals for nursing care are set, and the nursing interventions are determined; (ii) if the patients' needs are met and (iii) if goal achievement is regularly evaluated by including comments in nursing documents. In addition, the study aimed to describe the up-to-dateness of nursing care plans as well as the frequency of making daily notes. The data were collected on 36 wards of four residential homes. A 30% sample of the nursing documents on each ward was collected (n=332) using the Senior Monitor instrument. The documents studied were mainly nursing care plans and daily note sheets. Seventy-three per cent of the nursing home residents had an up-to-date nursing care plan at the time of data collection. The main results demonstrated that a written statement on the patient's mental ability was lacking in every fourth document although 75% of the patients suffer from at least moderate dementia in Finnish long-term care institutions. Development activities should also be targeted to the documentation of clear and concrete means by which patients' independent functioning is supported. In addition, evaluation was the area that warranted attention and development activities since only every fourth record included information on changes in the patients' functional capability. Although a lot of in-service training has been focused on improving the documentation practices, there is still a need for development. The means by which knowledge is transferred to guide the practice should be carefully considered. Also forms should be developed to meet the special requirements for recording nursing care in long-term care settings.     

Lack of effect of hepatic enzyme induction on metabolic control in patients with type 2 (non-insulin-dependent) diabetes

A placebo-controlled, double-blind crossover study was carried out in 11 non-insulin-dependent (type 2) diabetic patients to find out the effects of a hepatic enzyme inducer (phenobarbital, 100 mg/day for 2 months) on the metabolic control, plasma C-peptide, insulin, serum, and lipoprotein lipid levels. Phenobarbital induced a significant increase in hepatic antipyrine metabolizing activity, but no significant changes were found in fasting or postload blood glucose, plasma C-peptide, or insulin levels during the study. There was a significant increase in serum total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol, as well as in serum total and very low-density lipoprotein triglycerides, during phenobarbital treatment as compared with placebo.     

Cholesterol lowering effect of metformin in combined hyperlipidemia: placebo controlled double blind trial

Metformin, an antidiabetic biguanide derivative, prevents experimental atherosclerosis and induces structural changes in lipoproteins in experimental animals. In the present study we investigated the effect of metformin on serum lipoproteins and platelet function in 24 non-diabetic patients with type II B hyperlipidemia. The patients were randomly given metformin in two dosage levels (1.0 g/day and 2.0 g/day) and placebo for periods of nine weeks in a crossover trial. Metformin caused a dose dependent fall in the concentrations of total serum cholesterol and of LDL-cholesterol. The average concentration of total cholesterol was 8.54 +/- 0.22 (SE) mmol/l, 8.12 +/- 0.19 mmol/l and 7.79 +/- 0.15 mmol/l during placebo, metformin 1.0 g/day and 2.0 g/day treatments, respectively. Both metformin values differed significantly (P less than 0.05) from the placebo value. Thus there was an average fall of 8.1% in total cholesterol after the higher metformin dose. LDL-cholesterol was 5.25 +/- 0.23 mmol/l after placebo, falling by 3.1% and 9.6% after metformin doses of 1.0 g/day and 2.0 g/day, respectively. The concentrations of HDL-cholesterol and total serum triglycerides showed no significant changes. Body weight, blood glucose, plasma insulin, blood lactate, platelet function and urinary excretion of prostanoids remained unchanged during the study. The reduction of total- and LDL-cholesterol levels may be a welcome additional consequence of metformin during treatment of diabetic patients with hypercholesterolemia.     

Medical and psychology students' self-assessed communication skills: A pilot study

Objective

The purpose of this study was to describe how psychology and medical students assess their own competency and skills before and after training, in which role-play was used to teach interpersonal and communication skills.

Method

Interpersonal and communication skills were assessed with a semi-structured questionnaire before and after the training.

Results

The students of both medicine and psychology estimated their skill levels to be higher after the course. The psychology students estimated their skills for communication, motivating interviewing, empathy and reflection, and change orientation to be better at the end of the course. Medical students estimated their communication skills, motivating interviewing skills, and change orientation skills to be better at the end of the course.

Conclusion

Even a short period of training in interpersonal and communication skills can positively affect the self-assessed skills of the medical students.

Practice implications

In the future, it would be worthwhile to pay attention to reflective teaching practices in the training of both medical and psychology students. The cognitive and emotional components of these practices help students to develop their own communication skills.     

Circulating glucocorticoid bioactivity and serum cortisol concentrations in premature infants: the influence of exogenous glucocorticoids and clinical factors

OBJECTIVE: Glucocorticoids are widely used before preterm delivery and in preterm infants may bear serious adverse effects. Better knowledge about the circulating glucocorticoid milieu after glucocorticoid treatment could improve treatment modalities. Therefore, we investigated the influence of exogenous glucocorticoids and clinical factors on serum cortisol (F) levels and circulating glucocorticoid bioactivity (GBA) in preterm infants. DESIGN: Eighty-nine infants (gestational age (GA) 23.6-33.1 weeks at birth) were enrolled in a prospective cohort study in two tertiary neonatal centres. METHODS: Cord, day of birth (D0), fourth day (D4) and 36 weeks postmenstrual age serum F and GBA levels were measured. RESULTS: The cord GBA was 5.8-fold and D0 GBA 2.3-fold higher in the infants exposed to antenatal steroids within 12 h before birth when compared with those unexposed or exposed >7 days before birth (95% CI 3.8-8.6; P<0.0001, and 1.8-3.0; P<0.0001 respectively). In the infants treated with early postnatal dexamethasone, D4 GBA was 1.7-fold (1.3-2.2; P<0.0005) higher when compared with levels in the infants without this treatment. Clinical factors indicating perinatal distress, such as Apgar scores <7 and low GA, were associated with higher cord, D0 and D4 serum F levels. CONCLUSIONS: Both ante- and postnatally administered glucocorticoids increase circulating GBA not attributable to endogenous F. Perinatal distress and preceding glucocorticoid treatment need to be taken into account when circulating glucocorticoid milieu is evaluated in preterm infants. The GBA assay may prove to be a useful instrument in the development of new glucocorticoid treatment strategies.     

Facial asymmetry in children with either unilateral lambdoid craniosynostosis or positional posterior plagiocephaly

Background

In unilateral lambdoid craniosynostosis (ULC), the posteriorly situated lambdoid suture of the cranial vault fuses prematurely. Positional posterior plagiocephaly (PPP) causes flattening of the posterior side of the head, either through external forces or through underlying differences in brain development. Both conditions cause occipital flattening of the head, but the aetiology is different.

Materials and Methods

Eight ULC children were compared with 16 sex- and age-matched PPP children. 3D computer tomography scans of all 24 children were analysed with Dolphin imaging software. The location and symmetry of the temporomandibular joint (Co), and the symmetry of the maxillary anterior nasal spine (ANS) and the mandibular symphysis (Pgn) were analysed. Furthermore, the mandibular bone (Co–Pgn) length, corpus length, ramus height, positional changes in the external acoustic meatus (PoL) and the distance from the orbital margin to the articular fossa were measured.

Results

In all eight ULC children, the Co was anteriorly displaced on the affected side compared with the unaffected side. In all ULC and PPP children, the ANS, which is considered the bony maxillary midpoint, was shifted towards the affected side. In all ULC children, the mandibular bone (Co–Pgn) was shorter on the affected side. The PoL was antero-inferiorly positioned in all ULC children on the affected side compared with the unaffected side.

Conclusions

Our results show that both types of posterior plagiocephaly are associated with an asymmetric position of the Co and asymmetry of the mandible and maxilla. Facial asymmetry was more frequently seen in ULC than PPP children.     

Quality of institutional care of older people as evaluated by nursing staff

Aims. The aim of this paper was to report on the quality of institutional nursing of older people as evaluated by nursing staff in 2001 and to compare the responses with those obtained in 1998. Background. The healthcare division of one Finnish city authorised an outside survey of long‐term geriatric care in the hospitals providing such care in 1998. Based on the results, recommendations concerning the development of care of older people were issued. A re‐survey was conducted in 2001, using the same criteria of quality assessment. Methods. A survey research method was used. All the seven institutions providing long‐term geriatric care, including a total of 53 wards, participated. In 1998, a total of 607 questionnaires was returned. The response percentage was 78·6%. In 2001, a total of 573 questionnaires was returned. The response percentage was 76·8%. Results. The staff considered their possibilities to help geriatric patients best in the domain of physical care and slightly less good in the domain of psychosocial care. The differences in staff estimates between the two years were very small. More than 90% of the respondents considered their knowledge of physical care adequate. The nursing staff's evaluations were roughly similar in 1998 and 2001. More than 98% of the respondents considered the helping of older people important or moderately important in the other subdomains except sexual expression. According to the nursing staff, intentional or unintentional negligence in care was more common than physically or psychically offensive conduct. Observations concerning maltreatment had increased from 1998 to 2001. The staff reported both physical and mental fatigue. Nevertheless, the nursing staff appeared to be quite content with their current workplaces. Relevance to clinical practice. The findings indicated that geriatric care mostly aims to respond to the physical needs of older people. Nursing should, therefore, be developed and improved because mere satisfaction of physical needs is not enough to guarantee a good quality of life for older people in long‐term institutional care.     

Systemic efficacy of oncolytic adenoviruses in imagable orthotopic models of hormone refractory metastatic breast cancer

Conditionally replicating oncolytic adenoviruses represent a promising developmental strategy for the treatment of cancer refractory to current treatments, such as hormone refractory metastatic breast cancer. In clinical cancer trials, adenoviral agents have been well tolerated, but gene transfer has been insufficient for clinical benefit. One of the main reasons may be the deficiency of the primary adenovirus receptor, and therefore viral capsid modifications have been employed. Another obstacle to systemic delivery is rapid clearance of virus by hepatic Kupffer cells and subsequent inadequate bioavailability. In this study, we compared several capsid-modified oncolytic adenoviruses for the treatment of breast cancer with and without Kupffer cell inactivation. Replication deficient capsid-modified viruses were analyzed for their gene transfer efficacy in vitro in breast cancer cell lines and clinical samples and in vivo in orthotopic models of breast cancer. The effect of Kupffer cell depleting agents on gene transfer efficacy in vivo was evaluated. An aggressive lung metastatic model was developed to study the effect of capsid-modified oncolytic adenoviruses on survival. Capsid-modified viruses displayed increased gene transfer and cancer cell killing in vitro and resulted in increased survival in an orthotopic model of lung metastatic breast cancer in mice. Biodistribution of viruses was favorable, tumor burden and treatment response could be monitored repeatedly. Kuppfer cell inactivation led to enhanced systemic gene delivery, but did not increase the survival of mice. These results facilitate clinical translation of oncolytic adenoviruses for the treatment of hormone refractory metastatic breast cancer.
