A simple and effective treatment for hemorrhagic radiation proctitis using formalin

Radiation proctitis is a common complication of radiotherapy for pelvic malignancy. In the more severe form, it leads to intractable or massive hemorrhage, which may require repeated hospital admissions and blood transfusions. Medical therapy in patients with radiation proctitis is usually ineffective, whereas surgery is associated with a high morbidity and mortality. Eight patients (seven females and one male) with hemorrhagic radiation proctitis were Treated over a six-month period with endoluminal formalin. The technique used ensured minimal contact with formalin. The median age of the patients was 68 years (range, 42–73 years). Seven patients had had cancer of the uterine cervix, and one patient had had cancer of the prostate treated with radiotherapy at a median time of 30 months (range, 9–46 months) previously. The median duration of time of symptomatic rectal hemorrhage before formalin therapy was eight months (range, 1–12 months). The median number of units of blood transfused previously per patient was four (range, 2–32). The time taken for formalin therapy was 20 minutes (range, 10–70 minutes). One patient required repeat formalin application at two weeks. Bleeding ceased immediately in seven patients after formalin treatment. No further bleeding was noted, nor was any blood transfusion needed, at follow-up at four months (range, 1–6 months). Formalin therapy is a simple, inexpensive, and effective treatment for hemorrhagic radiation proctitis.     

Self-reported hypoglycaemia in insulin-treated patients with diabetes mellitus: results from the Singapore cohort of the International Operations Hypoglycaemia Assessment Tool study

INTRODUCTIONHypoglycaemia constitutes a significant barrier to achieving glycaemic control with insulin in both Type 1 (T1DM) and Type 2 diabetes mellitus (T2DM). The International Operations Hypoglycaemia Assessment Tool (IO HAT) study was designed to determine the incidence of hypoglycaemia in insulin-treated patients with T1DM and T2DM.METHODSThe IO HAT study retrospectively and prospectively assessed the incidence of hypoglycaemia in patients with insulin-treated diabetes mellitus in nine countries. This sub-analysis included patients from Singapore with T1DM or T2DM who were aged ≥ 21 years and had completed two self-assessment questionnaires (SAQ1 and SAQ2).RESULTSOf the 50 T1DM and 320 T2DM patients who completed the SAQ1, 39 T1DM and 265 T2DM patients completed SAQ2; 100% and 90.9%, respectively, experienced at least one hypoglycaemic event prospectively. The incidence rates of any hypoglycaemia were 49.5 events per patient-year (EPPY) and 16.1 EPPY for T1DM and T2DM patients, respectively, in the four-week prospective period. Hypoglycaemia rate did not differ in terms of glycated haemoglobin level. The vast majority of T1DM or T2DM patients (92.0% and 90.7%, respectively) knew the overall definition of hypoglycaemia before study participation, although over half of the patients (T1DM 54.0%, T2DM 51.9%) defined hypoglycaemia based only on symptoms.CONCLUSIONHigh proportions of insulin-treated patients with diabetes mellitus in Singapore reported hypoglycaemic events prospectively, showing that they had underreported hypoglycaemic episodes retrospectively. Patient education can help in improving hypoglycaemia awareness and its management in the region.     

Non-alcoholic fatty liver disease in a young multiracial Asian population: a worrying ethnic predilection in Malay and Indian males

Purpose

Previous studies on multiracial Malaysian populations found inordinately high prevalence of NAFLD among Malays and Indians. Whether the prevalence of NAFLD is different among young adults of different ethnic origins is not known. We aimed to determine racial differences in NAFLD in a young multiracial Malaysian population and associated factors.

Methods

This was a cross-sectional study on medical students from the University of Malaya. Diagnosis of NAFLD was by transabdominal ultrasonography and following exclusion of significant alcohol intake and other causes of chronic liver disease.

Results

Data of 469 subjects were analyzed (mean age 23.2 ± 2.4 years, 40.3 % male). The racial distribution was: Chinese 53.9 %, Malay 30.5 % and Indian 15.6 %. The overall prevalence of NAFLD was 7.9 %. Subjects with NAFLD were older, had greater BMI and WC, higher SBP and DBP, higher FBS, serum TG and LDL levels, and lower serum HDL level. The prevalence of NAFLD was higher among males compared to females (17.9 % vs. 3.3 %, p < 0.001). The highest prevalence of NAFLD was seen among Indian and Malay males at 33.3 and 25.5 %, respectively, compared to Chinese males at 6.8 % (p < 0.001). No significant difference was seen among females of different races. Independent factors associated with NAFLD were male gender, obesity and hypertriglyceridemia.

Conclusions

The difference in prevalence of NAFLD among the different ethnic groups can be observed as early as young adulthood. An inordinately high prevalence of NAFLD was observed among Malay and Indian males consistent with the higher prevalence of obesity in these groups.
