Diabetic peripheral neuropathy (DPN) has been linked to hyperglycaemia and long duration of uncontrolled type 2 diabetes mellitus (T2DM) as measured by glycosylated haemoglobin (HbA1c). To our knowledge the estimated duration between diagnosis and developing DPN and the level of HbA1c have not yet been investigated in Sudanese patients with type 2 DM. Therefore, this study aims to investigate the relationship between the duration of diabetes and HbA1c with nerve conduction velocity (NCV) in patients with type 2 DM. Methods: This cross-sectional study recruited 63 male and female patients with T2DM who attended the diabetic outpatient clinic of Academy Charity Teaching Hospital (ACTH) and Alzaytouna Private Hospital for Nerve Conduction Velocity (NCV) and electromyography (EMG) tests. Nerve conduction was done by using ADInstruments PowerLab series 26. SPSS was used to analyse the data and p-value < 0.05 was considered significant. Results: The mean duration of DM was 14.7 (± SD 9.24) years and the mean age of participants was 57.71 (± SD 12.2) years. The most common symptom was numbness (50%). Pearson's correlation test revealed a significant negative correlation between HbA1c and nerve conduction velocity (r = 0.4, p < 0.05) and negative significant correlation between the duration and the amplitude (r = 0.35, p < 0.05). Conclusion: There is a slowing of nerve conduction velocity in type 2 diabetic patients, which is accelerated by the poor glycaemic control (HbA1c). These findings support the need for tight glycaemic control to avoid drastic neuropathic complications of diabetes.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"15 1","pages":"46 - 51"},"PeriodicalIF":0.5,"publicationDate":"2021-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84286628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morphometric VFs were identified using the semi-quantitative Genant method. Descriptive analysis was undertaken using Student’s t-test, the Mann–Whitney U-test and the chi-square test. Results: In the 197 subjects enrolled, the median age was 72.0 years (IQR 67.0–78.5 years) and morphometric VFs were identified in 41 subjects (20.8%). The prevalence of VFs increased with age, and while more common in women compared with men (23.8% vs. 13.0%), this was not significant (p 0.095). There was no difference in the prevalence of VFs between African and Indian subjects (23.4% vs. 17.4%; p 0.240), nor CRFs between subjects with and without VFs.

Published randomised control trials and crossover control trials were systematically examined to establish the differences in the effect of single-bout exercise on glucose control and insulin sensitivity in individuals with type 2 diabetes. Methods: Using PRISMA guidelines on three electronic databases, studies that tested the effects of a single bout of exercise on glucose control and insulin sensitivity in T2D were identified. To be included, studies had to meet the PRISMA criteria and contain data on the effects of a single bout of exercise on blood glucose and/or insulin resistance in individuals with T2D. Results: Three of the 205 articles met the inclusion criteria. All of the studies prescribed a single bout of continuous aerobic exercise at 40–60% heart rate reserve (HRR), 60% HRR, or 73% VO2 peak. Aerobic exercise was associated with improved glucose control when compared with resistance exercise. Continuous aerobic exercise significantly lowered average glucose during the first 24 hours post-exercise. Interval walking decreased mean and maximal blood glucose when compared with that in control. Conclusions: In conclusion, the findings of this review suggest high-intensity interval training to be the most effective form of exercise.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"30 1","pages":"24 - 28"},"PeriodicalIF":0.5,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77202365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In South Africa, little is known about the impact of PHPT on skeletal health. Objective: To determine the prevalence of decreased bone mineral density (BMD), vertebral fractures and osteitis fibrosa cystica in patients with PHPT who underwent parathyroidectomy. Methods: Retrospective study of patients who underwent parathyroidectomy for PHPT at Tygerberg Hospital in Cape Town, from January 2010 to December 2019. Clinical, biochemical and BMD parameters are described. Results: Final analysis included 56 patients (median age 63.5 years; 80.4% female). Initial calcium, parathyroid hormone (PTH) and 25-hydroxyvitamin D (25[OH]D) levels were 2.93 mmol/l, 19.4 pmol/l and 34.0 nmol/l, respectively. Of the total cohort, 71.4% had decreased BMD. The prevalence of osteoporosis and osteopenia in postmenopausal women and men ≥ 50 years was 50.0% and 39.1% respectively; low bone mass for age in premenopausal women and men < 50 years was 20.0%. Vertebral fractures were seen in 21.2% of patients on radiography. Osteitis fibrosa cystica was present in five patients (9.6%). PTH levels were significantly elevated in patients with osteoporosis compared with those with normal BMD (36.4 vs. 16.1 pmol/l; p = 0.02).

A commercially available immunohistochemical stain for SDHB has excellent correlation with SDH gene mutation status when staining is lost. This abnormal loss of staining can identify potential familial tumours and tumours with a higher risk of malignant behaviour. The prevalence of SDH deficiency in the South African setting has not been published previously. Methods: A retrospective laboratory-based study at Tygerberg Hospital in Cape Town used immunohistochemistry on archived tumour tissue to assess loss of SDHB staining in phaeochromocytomas and paragangliomas submitted to the histopathology laboratory (National Health Laboratory Service) between 2005 and 2015. Results: Tumour tissue from 52 patients was tested. In total, 36% showed loss of staining. Loss of staining was significantly correlated with a younger age at presentation (z = −3.59, p < 0.001). The median age of those who showed loss of staining was 26 years (IQR 21–41), compared with 50.5 years (IQR 36–61) for those who showed retained staining. The inter-observer agreement in the interpretation of the immunohistochemical stain was excellent (Cohen’s kappa = 0.917; 95% confidence interval, 0.81–1, p < 0.001). Conclusion: Approximately one-third of phaeochromocytomas and paragangliomas in our setting are likely to be associated with germline mutations in one of the SDH genes. Immunohistochemical testing of tumour tissue can identify this group to allow better prognostication and appropriate genetic testing and counselling.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"4 1","pages":"9 - 15"},"PeriodicalIF":0.5,"publicationDate":"2020-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84849595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aims: The prevalence, aetiology and course of thyrotoxicosis in women with hyperemesis gravidarum (HG) were studied. Methods: Women admitted for HG, who underwent thyroid function evaluation between 1 August 2016 and 30 April 2019, were studied. Laboratory data included baseline human chorionic gonadotropin (hCG) and baseline (t1), discharge (t2) and follow-up (t3) thyroid function tests (thyroid stimulating hormone [TSH] and free thyroxin [fT4]). Available TSH receptor antibody status was assessed. Results: Eighty-two patients were included. The incidence of thyrotoxicosis was 49% based on local laboratory TSH range and 48% if trimester-specific ranges used. In the majority of normal pregnancies, thyrotoxicosis was hCG-mediated (72.5%), 15% were confirmed to have Graves’ disease and 12% had a molar pregnancy. Very high fT4 levels (> 40 pmol/l) at baseline [t1] were documented in 24% of women with hCG-mediated thyrotoxicosis. Clinical features were absent in a third of women with Graves’ disease and the diagnosis was reliant on positive antibody status. Free T4 values declined from (t1) to later in gestation (t3) (p < 0.001). Conclusion: The incidence of thyrotoxicosis in women with HG is high. Free-T4 values decrease with clinical stabilisation of HG, suggesting a contribution of dehydration to the large variation in baseline fT4 measurements. Testing for TSH-receptor antibodies should be considered in women with TSH < 0.01 pmol/l and persistent fT4 elevation on follow-up. Final review of thyroid function should be performed after 15 weeks’ gestation.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"61 1","pages":"1 - 8"},"PeriodicalIF":0.5,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83063346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying defaulting reasons in diabetes clinics can provide potential interventional areas. Methods: Data of patients booked for the Edendale Hospital diabetes clinic (attendees and defaulters) between August 2019 and February 2020 were used to determine whether control in defaulters differed from attendees and to analyse defaulting reasons. Results: A total of 581 patients living with diabetes (PLWD) attended; 213 defaulted (defaulting rate 26.79%). Defaulters (1) had poorer glycaemic and lipid control; (2) with HIV infection and type 2 DM (T2DM) had inferior glycaemic control; (3) performed more self-monitoring of blood glucose (SMBG). Substantially more females defaulted across all categories. They had poorer glycaemia and lipid control with higher body mass index. The commonest defaulting reasons were forgetting appointments, too many clinics (TMC), patient sick and work commitments (44.3% vs. 24.5% vs. 13.1% vs. 10.8%). Within HIV-infected defaulters, reasons ranged from TMC, work commitments and other reasons to forgot appointment (57.7% vs. 26.1% vs. 23.8% vs. 13.8%). A significant number of HIV-infected and patients on antiretroviral therapy, of both sexes, with T2DM, defaulted secondary to TMC. Patients with hypertension and chronic kidney disease (CKD) defaulted due to TMC. Bivariate analysis revealed that being a pensioner, increased age, employment and presence of T2DM were significantly associated with being sick. Older patients defaulted in poor weather while younger patients specified school/work commitments. Patients who complained of TMC had higher creatinine levels. Conclusions: The defaulting rate in PLWD remains high. Defaulters had sub-optimal glycaemic and lipid control. TMC proved to be significant for patients with chronic diseases (HIV infection, hypertension and CKD) highlighting the need for combined communicable and non-communicable diseases clinics. Defaulting females and HIV-infected PLWD had high prevalence of cardiovascular risk factors. Afternoon clinics might assist with work/school commitments.

Methods: The Interactive Qualitative Analysis (IQA) was used to construct and describe a cognitive mind map of students’ perceptions of their self-management living with DM. Results: An analysis of the participants’ mind map representing students living with DM revealed eight main components (affinities), namely: Social awareness and acceptance, Food available on campus, Keeping insulin cool, Independent lifestyle, Adjusting by cooking, Hurdles in the academic environment, Causes of changing blood sugar and Adapting to effects of changing blood sugar. Conclusion: The final perceptual system was an informative representation of the self-management of students living with DM. The system reflects barriers to compliance with self-management facing students living with DM. The system produced four recognisable loops or cycles, namely the Ignorance loop, the Revision loop, the Developing loop and the Self-management loop. These loops created pathways through the system for the students living with DM to find a way to better self-management.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"25 1","pages":"51 - 56"},"PeriodicalIF":0.5,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79650768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
