False-negative 99mTc-sestamibi scans: factors and outcomes in primary hyperparathyroidism.

Primary hyperparathyroidism has emerged as a prevalent endocrine disorder in clinical settings, necessitating in most cases, surgical intervention for the removal of the diseased gland. This condition is characterised by overactivity of the parathyroid glands, resulting in excessive parathyroid hormone production and subsequent disturbances in calcium homeostasis. The primary mode of management is surgical treatment, relying on the accurate localisation of the pathological parathyroid gland. Precise identification is paramount to ensuring that the surgical intervention effectively targets and removes the diseased gland, alleviating the hyperfunctioning state. However, localising the gland becomes challenging, as discrepancies between the clinical manifestation of active parathyroid and radiological identification are common. Based on our current knowledge, to date, no comprehensive review has been conducted that considers all factors collectively. This comprehensive review delves into the factors contributing to false-negative 99mTc-Sestamibi scans. Our research involved an exhaustive search in the PubMed database for hyperparathyroidism, with the identified literature meticulously filtered and reviewed by the authors. The results highlighted various factors, including multiple parathyroid diseases, nodular goitre, mild disease, or the presence of an ectopic gland that causes discordance. Hence, a thorough consideration of these factors is crucial during the diagnostic workup of hyperparathyroidism. Employing intraoperative PTH assays can significantly contribute to a successful cure of the disease, thereby providing a more comprehensive approach to managing this prevalent endocrine disorder.

Glycemic and lipids control in patients with diabetes and cardiovascular or renal diseases across all the government health sectors in the Emirate of Dubai, United Arab Emirates.

The guidelines suggest setting the glycemic and lipid targets according to the stage of the disease and other co -existing complications in the patients with diabetes. AIMS: We aimed to evaluate the HbA1c and lipids level in patients with high risk diabetes from 2012-2016, attending different level of care in Dubai health authority. MATERIALS AND METHODS: This is a retrospective analysis of the electronic medical records of all patients who attended the Dubai Health authority between 2012-2016. All patients with an ICD code of any type of diabetes in addition to cardiovascular or renal diseases were. Patients were categorized based on their HbA1c into control of<7.5, 7.5 - 8, and >8%. While lipids were categorized as f LDL < 70 mg/dl, and the Non-HDL <100 mg/dl. RESULTS: Out of total number of 26647 patients diagnosed with diabetes, 2015 patients did fit the criteria of this study. The desired mean of HbA1c of <7.5% achieved by 21.76% and 28.94% in T1DM and T2DM, respectively. The LDL of < 70 mg/dl was achieved by 27.8% of the patients. CONCLUSION: In patients with diabetes and multiple complications, the glycemic and lipids control is suboptimal. However, the pattern showed numerical improvement over the years.

Safety of Sodium-Glucose Cotransporter 2 Inhibitors (SGLT2-I) During the Month of Ramadan in Muslim Patients with Type 2 Diabetes.

OBJECTIVES: Sodium-glucose cotransporter 2 inhibitors (SGLT2-I) are a new class of antidiabetic drugs that might increase the risk of dehydration and hypoglycemia, particularly during the month of Ramadan in which Muslims abstain from eating and drinking for 14-16 hours daily. We aimed to provide real-life evidence about the safety of SGLT2-I during Ramadan. METHODS: All patients over the age of 18 years on SGLT2-I before Ramadan 2016 who would be fasting during Ramadan were included. Demographic data, detailed medical history including comorbidities and medication profile, and laboratory results were collected before and after Ramadan. We also conducted a phone interview to evaluate the frequency and severity of hypoglycemia and dehydration. RESULTS: Of the total of 417 patients, 113 (27.0%) experienced hypoglycemic events, and 93 of these (82.3%) checked their blood glucose using a glucometer. Confirmed hypoglycemia (< 70 mg/dL) was observed in 78 (83.8%). The hypoglycemic events were significantly more frequent in the SGLT2-I plus insulin-treated group than in those treated with SGLT2-I plus oral hypoglycemic agents group (p < 0.001). Confirmed hypoglycemic events were more frequent in those using SGLT2-I plus intensive insulin compared to those using SGLT2-I plus basal insulin (p = 0.020). Symptoms of dehydration were seen in 9.3% (n = 39) of the total population. We observed statistically significant reductions in glycated hemoglobin and weight by the end of Ramadan (p < 0.001). There were no significant changes in lipid profile and creatinine levels by the end of the study. CONCLUSIONS: The use of insulin in combination with SGLT2-I increases the risk of hypoglycemia during Ramadan. Hypoglycemic events were mild and did not require hospital admission. However, careful monitoring during prolonged fasting is warranted. No significant harmful effects on renal function result from treatment with SGLT2-I during Ramadan.
