Purpose:
Accelerated atherosclerosis is a major complication in patients with end-stage renal disease and it plays an important role in the pathogenesis of erectile dysfunction (ED). However, the association between aortic calcification burden and the severity of ED remains unclear. The aim of the present study was to investigate this association in men undergoing dialysis.
Materials and Methods:
This cross-sectional study included 71 men undergoing peritoneal dialysis and/or hemodialysis between July 2016 and May 2018 at Mutsu General Hospital. ED was assessed with the Sexual Health Inventory for Men (SHIM). Patients were divided into the mild/moderate (SHIM score ≥8) and severe ED groups (SHIM score ≤7). Aortic calcification index (ACI) was examined as a clinical indicator of abdominal aortic calcification. Multivariable logistic regression analysis was performed to identify the significant factors associated with severe ED.
Results:
The median age of the study participants was 64 years; all had ED, with 64.8% having severe ED. In the multivariable analyses, a slight association was observed between ankle-brachial index and severe ED (odds ratio [OR], 0.058; p=0.072), whereas ACI was significantly associated with severe ED (OR, 1.022; p=0.022).
Conclusions
Aortic calcification burden was independently associated with severe ED.

Purpose:
To investigate the association between skin advanced glycation end-products (AGEs) levels, blood antioxidative vitamin and carotenoid concentrations, and severe erectile dysfunction (ED) in community-dwelling men.
Materials and Methods:
This cross-sectional study used the 5-Item International Index of Erectile Function to identify 335 community-dwelling men with ED. The accumulation of skin AGEs was assessed noninvasively by measuring skin autofluorescence. Background-adjusted multivariable logistic regression analyses using the inverse probability of treatment weighting method were performed to evaluate the effects of AGEs, vitamins, and carotenoids on severe ED. Moreover, multiple linear regression analyses were performed to assess the association between skin AGEs levels and serum carotenoid concentrations.
Results:
The median age of study participants was 57 years. Of the 335 men, 289 (86.3%) and 46 (13.7%) were classified into the mild/moderate and severe ED groups, respectively. Multivariable analyses revealed that skin AGEs levels, blood vitamins C and E, lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene, total lycopene, and cis-lycopenes concentrations were significantly associated with severe ED, whereas all-trans lycopene concentrations were not. In the multiple linear regression analyses, serum zeaxanthin concentrations were negatively and significantly correlated with skin AGEs levels.
Conclusions
Higher skin AGEs levels and lower blood antioxidative vitamin and carotenoid concentrations were significantly associated with severe ED. Serum zeaxanthin levels were negatively and significantly correlated with skin AGEs levels, suggesting the possible effects of zeaxanthin on ED by decreasing tissue AGEs levels.

Purpose:
To evaluate the impact of severe erectile dysfunction (ED) on future major adverse cardiovascular events (MACE) in men on dialysis.
Materials and Methods:
This prospective cohort study included 71 men on dialysis. ED was assessed using the Sexual Health Inventory for Men (SHIM). Men were divided into the mild/moderate ED (SHIM score ≥8) and severe ED (SHIM score ≤7) groups. The primary endpoint was MACE-free survival. MACE was a composite of myocardial infarction, cardiovascular death, and stroke. The secondary endpoints were cardiac event-free survival and overall survival (OS). Moreover, the predictive abilities of severe ED for 5-year MACE, 5-year cardiac events, and 5-year overall mortality were evaluated.
Results:
The median age and follow-up period of the included men were 64 years and 58 months, respectively. The median SHIM score was 4.0; all had a degree of ED, and 64.7% had severe ED. In the background-adjusted multivariable analyses, severe ED was not significantly associated with shorter MACE-free survival (hazard ratio [HR], 1.890; 95% confidence interval [CI], 0.533–6.706; p=0.324), cardiac event-free survival (HR, 2.081; 95% CI, 0.687–6.304; p=0.195), and OS (HR, 0.817; 95% CI, 0.358–1.863; p=0.630). Severe ED did not significantly improve the predictive abilities for 5-year MACE, 5-year cardiac events, and 5-year overall mortality (p=0.110, p=0.101, and p=0.740, respectively).
Conclusions
ED severity was not associated with shorter MACE-free survival, cardiac event-free survival, or OS, and ED severity could not improve the predictive abilities for these outcomes in men undergoing dialysis.

BACKGROUND:
The lingual nerve plays an important role in multiple functions, including gustatory sensation and contact sensitivity and thermosensitivity. Misdiagnosed conservative treatments for serious lingual nerve (LN) injuries can induce the patient to serious mental disability. After continuous observation and critical diagnosis of the injury, in cases involving significant disruption of lingual nerve function, microneurosurgical reconstruction of the nerve is recommended. Direct anastomosis of the torn nerve ends without tension is the recommended approach. However, in cases that present significant gaps between the injured nerve ends, nerve grafts or conduits (tubes of various materials) are employed. Recently, various reconstruction materials for peripheral nerves were commercially offered especially in the USA, but the best method and material is still unclear in the world. There currently exists no conventional protocol for managing LN neurosensory deficiency in regard to optimal methods and the timing for surgical repair. In Japan, the allograft collagen nerve for peripheral nerves reconstruction was permitted in 2017, and we tried to use this allograft nerve and got a recommendable result.CASE PRESENTATION: This report is a long-term abandoned torn LN reconstructed with allograft nerve induced by the lower third molar extraction.
CONCLUSIONS
In early sick period, with the exact diagnosis, the LN disturbance should be managed. In a serious condition, the reconstruction with allograft nerve is one of the recommendable methods.

Purpose: In this study, we performed a longitudinal examination of the occurrence of homeboundness among community-dwelling elderly individuals and changes in associated factors, including the sense of coherence (SOC).Methods: A questionnaire survey was conducted targeting community-dwelling elderly individuals to evaluate homebound status, a basic checklist (CL), and SOC. Among these individuals, frail elderly people who maintained a non-homebound state were extracted and a follow-up survey was carried out one year later. Those who maintained the non-homebound state one year later were classified into the maintenance group and those who became socially withdrawn were classified into the transition group. Factors predicting the homebound state one year later were examined using multiple logistic regression analysis. Furthermore, the changes in CL and SOC between the transition and maintenance groups were compared.Results: In the transition group, motor function, cognitive function, and sense of manageability on the initial survey were significantly lower than those in the maintenance group. Significant correlations were noted in the homebound transition group with lack of money management (OR: 3.04, 95% CI: 1.19-7.82) and a declined sense of manageability (OR: 0.82, 95% CI: 0.69-0.99). Depression and the sense of manageability had also significantly deteriorated one year later compared with those in the maintenance group.Conclusion: This study suggests that individuals who transition to a state of homeboundness have a slightly lower SOC than those who maintain their non-homebound status.

Cholesteatoma is a cystic non tumorous lesion of the temporal bone that has the ability to destroy nearby structures by its power to cause bone resorption and as a result, fatal complications prevail. We aimed to conduct a comprehensive review for pathogenesis of acquired cholesteatoma, bone resorption mechanisms, and offer a future vision of this serious disease. We have reviewed different theories for pathogenesis of acquired cholesteatoma including the most relevant and updated ones with special emphasis on the mechanisms of bone resorption through Medline/PubMed research using the keywords ‘aetiopathogenesis, bone resorption, acquired cholesteatoma, temporal bone, and cytokines.’ In order to strengthen our study, we searched the reference lists of identified reviews. Cholesteatoma is a subject of debate among otolaryngologists since it was prescribed firstly. Over many decades, several theories were postulated for aetiopathogenesis of cholesteatoma with a tendency to follow more than one theory to explain the proper nature of that disease. Until now, the mechanism of bone resorption has yet to be more clarified. In the last century, a leap has occurred in the field of biomolecular cholesteatoma research which improved our knowledge about its pathophysiology and bone destructive mechanism. However, surgery is still the only available treatment. We conclude that discovery of new therapeutic choices for cholesteatoma other than surgery by the use of anti-growth, anti-proliferative, apoptotic agents as well as medications that antagonize osteoclastogenesis should be the main concern in the future clinical and experimental research work. Also, searching for predictors of the aggressiveness of cholesteatoma can affect the timing of intervention and prevent occurrence of complications.

Objective : Although current preventative care policies consider the issue of the homebound elderly to be important, effective means of intervention have not been established. Therefore, it is necessary to elucidate the relevant causes of the poorly understood “homebound” problem. As little expertise exists on the social and psychological factors of those who are homebound, this study focuses on the sense of coherence (SOC) —a new estimate of the psychosocial factors involved in being homebound—and examines the connection between being homebound and SOC.
Methods : A mail survey was conducted among 1,895 elderly adults, none of whom had been issued a Certification of Long-Term Care Need. Survey items included basic attributes, physical characteristics, psychological and socioenvironmental characteristics, and the condition of being homebound. Furthermore, SOC was investigated as part of the psychosocial and environmental evaluation. The 853 respondents chosen for the analysis were divided into three groups depending on their level of homeboundedness, and an ordered logistic regression analysis was conducted using homeboundedness as the dependent variable.
Results : The following items were found to have a significant association with homeboundedness : age, sex, low motor function, depressive tendencies, low SOC, and the low TMIG Index of Competence.
Discussion : This study identified a relation between being homebound and SOC, suggesting that in addition to interventions for depression and motor function, new SOC focused aid must be considered in the prevention of homeboundedness.

Journal of International Health 2011;26(2):119-129
Introduction
Millennium development goal 5 (MDG 5) is to reduce the maternal mortality rate by 75%. Due to the shortage of medical doctors in sub-Saharan African countries, midwives have been compelled to take an important responsibility for the outcome of delivery. Therefore, to achieve MDG 5, strengthening midwives’ /professional ability is essential. However, less attention has been paid to the quality of midwifery care.
Objective
This study investigated the process of delivery care provided by midwives in the labor room at a public hospital in Tanzania and assessed the quality of midwifery care.
Methods
1.Data collection from delivery records
2.Observation of delivery care at the point of delivery in the labor ward.
I conducted an observational study in the delivery room of Mwananyamala Hospital in Dar es Salaam, the capital of Tanzania, for a total of 43 hours over 7 days.
3.Semi-structured interviews were conducted with 10 midwives at the hospital.
In our evaluation and analysis, the classification of practices during normal birth published by WHO were used as a benchmark.
Results
There were 257 deliveries during the 7days of observation. Still birth occurred in 15 cases. The average maternal age was 23.8 years old and 55.5% were primiparas. Since only 3 midwives working in three shifts conducted all deliveries, the shortage of staff was obvious.We noted three issues of midwifery care as follows:
1.Delivery care was not mother-centered.
2.Continuous and careful monitoring of labor was not performed.
3.Medical treatment and drugs were administrated inappropriately and may cause rupture of the uterus and hemorrhage.
Conclusion
To achieve the goal of MDG5, it is necessary not only to focus on the outcome indicator but also to improve the quality of midwifery care.

We describe a 38-year-old, severely emaciated female with slowly progressive type 1 diabetes mellitus (SPIDDM), who had hypoglycemia due to fasting and an extremely low energy intake. After being diagnosed with diabetes mellitus (DM), she took in only 300-500 kcal per day and her weight had decreased to 30 kg, with a body mass index (BMI) of 11.4 kg/m2. She was admitted with hypoglycemia, and SPIDDM was confirmed by nearly-completely ceased insulin secretion and seropositivity towards anti-GAD antibody. After appropriate dietary therapy and insulin administration, she recovered from a state of emaciation and her glucose metabolism was restored. With this patient it proved very effective for the general physician to coordinate treatment for both diabetes and an eating disorder.
