Background

We investigated the prevalence of electrolyte imbalance and the relationship between serum electrolyte and anterior pituitary hormone levels in patients with Sheehan's syndrome.

Methods

In a retrospective study, we investigated 78 patients with Sheehan's syndrome. We also included 95 normal control subjects who underwent a combined anterior pituitary hormone stimulation test and showed normal hormonal responses.

Results

In patients with Sheehan's syndrome, the serum levels of sodium, potassium, ionized calcium, magnesium, and inorganic phosphate were significantly lower than those in control subjects. The prevalence of hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia, and hypophosphatemia in patients with Sheehan's syndrome was 59.0% (n=46), 26.9% (n=21), 35.9% (n=28), 47.4% (n=37), and 23.1% (n=18), respectively. Levels of sodium and ionized calcium in serum were positively correlated with levels of all anterior pituitary hormones (all P<0.05). Levels of potassium in serum were positively correlated with adrenocorticotrophic hormone (ACTH) and growth hormone (GH) levels (all P<0.05). Levels of inorganic phosphate in serum were positively correlated with levels of thyroid-stimulating hormone, prolactin, and GH (all P<0.05), and levels of magnesium in serum were positively correlated with delta ACTH (P<0.01).

Conclusion

Electrolyte imbalance was common in patients with Sheehan's syndrome. Furthermore, the degree of anterior pituitary hormone deficiency relates to the degree of electrolyte disturbance in patients with this disease.

BACKGROUND
Cardiovascular risk is higher among people with diabetic nephropathy than among those with normal renal function. Carotid intima-media thickness (IMT) is an independent predictor of cardiovascular mortality in type 2 diabetic patients. However, the relationship between carotid IMT and diabetic nephropathy is not well known. The aim of our study was to elucidate whether carotid IMT is associated with progression of diabetic nephropathy in type 2 diabetic patients. METHODS: We recruited a total of 354 type 2 diabetic patients with diabetic nephropathy. Renal function was evaluated by serum creatinine levels, estimated glomerular filtration rate (eGFR), and urinary albumin/creatinine ratio (ACR). Carotid IMT was assessed using B-mode ultrasound by measuring generally used parameters. Baseline-to-study end changes in eGFR were calculated, and the yearly change of eGFR (mL/min/yr) was computed. RESULTS: Age, diabetes duration, ACR, and eGFR were significantly correlated with mean or maximal carotid IMT; however, lipid profiles, HbA1c, and blood pressure were not correlated. The mean yearly eGFR change was -4.9 +/- 5.3 mL/min/yr. The yearly eGFR change was negatively correlated with mean and maximal carotid IMT. After adjusting for age and diabetes duration, the mean IMT is an independent predictor of yearly eGFR change. CONCLUSION: Carotid IMT may be a predictor of diabetic nephropathy progression in patients with type 2 diabetes.

AbstractAbstract PDF
Hypoglycemia in diabetic patients is usually caused by excessive exogenous insulin or the administration of an insulin secretagogue relative to the prevailing glucose concentration. Thus, the clinical manifestations of hypoglycemia are usually not observed in diabetic patients after either insulin or an oral hypoglycemic agent is discontinued. In contrast, diabetic ketoacidosis results from relative or absolute insulin deficiency. Although about 40% of diabetic patients who inject human insulin have insulin antibodies, these antibodies seldom significantly affect the glycemic control. It has not been reported in the literature that insulin antibody in the setting of human insulin therapy is associated with diabetic ketoacidosis and subsequent hypoglycemia. We describe here a rare case of spontaneous hypoglycemia due to insulin antibody after the improvement of diabetic ketoacidosis in a patient with type 2 diabetes mellitus and who had been treated with human insulin.

AbstractAbstract PDF
BACKGROUND
The initial insulin dose is often determined by clinical experience or with a formula using the body weight. However, it may be difficult to determine the initial insulin dose because various factors such as insulin sensitivity and the glycemic status can influence the insulin requirement. The purpose of this study was to assess the factors that influence the initial insulin requirement in insulin naive patients with type 2 diabetes mellitus. METHODS: A total 128 patients who were admitted for glycemic control were investigated. The patients were managed with long-acting insulin glargine and rapid-acting insulin lispro. RESULTS: The basal insulin requirement was positively correlated with waist circumference, body mass index (BMI), the HbA1C, AST, ALT, fasting plasma glucose and 2-hour postprandial glucose levels and the homeostasis model assessment of insulin resistance (HOMA-IR), but it was negatively correlated with age and the stimulated C-peptide level. The daily insulin requirement was positively correlated with waist circumference, BMI, the HbA1C, AST, ALT, triglyceride, fasting plasma glucose and 2-hour postprandial glucose level and HOMA-IR, but it was negatively correlated with age. On the multiple linear regression analysis, the basal insulin requirement was independently associated with BMI (beta = 0.507, p < 0.001), the 2-hour postprandial glucose level (beta = 0.307, p < 0.001), the ALT level (beta = 0.214, P = 0.015) and the meal-stimulated C-peptide level (beta = -0.209, P = 0.010). The daily insulin requirement was independently associated with BMI (beta = 0.508, p < 0.001) and the 2-hour postprandial glucose level (beta = 0.404, p < 0.001). CONCLUSION: Our results show that the BMI and 2-hour postprandial glucose level are useful predictors of the initial insulin requirement in insulin naive type 2 diabetic patients. It may be prudent to consider the other various factors that influence the insulin requirement together when insulin therapy is required.

AbstractAbstract PDF
Intramural hematoma of the aorta is a variant of aortic dissection characterized by the absence of direct communication between the false lumen and the true lumen of the aorta. Primary aldosteronism, which is an uncommon cause of hypertension, may direct alter arterial structure through the pleiotropic effects of aldosterone as well as pressure-mediated indirect alterations. There have been several reported cases of aortic dissection in patients with primary aldosteronism, which suggests a causal relationship between the two diagnostic entities. However, intramural hematoma has not been described in a patient with primary aldosteronism. We describe a case of aortic intramural hematoma in a patient with primary aldosteronism and speculate about the causal relationship between these two entities.

AbstractAbstract PDF
BACKGROUND
In patients with hypoglycemia due to endogenous hyperinsulinemia such as insulinoma or insulin autoimmune syndrome, little is known about the counterregulatory hormone response to spontaneous hypoglycemia. We therefore compared hormone responses during spontaneous hypoglycemia due to endogenous hyperinsulinemia with those at the end of a 72-hour fast. METHODS: We measured glucagon, epinephrine, cortisol, and growth hormone responses during spontaneous hypoglycemia in 8 patients with insulinoma and 18 patients with insulin autoimmune syndrome. We also assessed these responses in 13 normal control subjects who underwent a 72-hour fast. RESULTS: In patients with insulinoma (median serum glucose level, 35.0 mg/dL), plasma glucagon levels (median, 42.9 vs. 76.2 pg/mL, respectively; P < 0.05) were lower than those in control subjects (serum glucose level, 62.5 mg/dL), whereas, there were no statistically significant differences in the other hormone responses between the two groups. In contrast, in the patients with insulin autoimmune syndrome (median serum glucose level, 34.5 mg/dL), plasma glucagon levels (median, 73.7 vs. 76.2 pg/mL, respectively) were lower than those in the control subjects, but there was no statistically significant difference between the two groups. There were no statistically significant differences in counterregulatory hormone responses during spontaneous hypoglycemia between patients with insulinoma and patients with insulin autoimmune syndrome. CONCLUSION: Our results suggest that defective glucagon secretion in patients with insulinoma rather than insulin autoimmune syndrome may contribute to hypoglycemia in addition to hyperinsulinemia.

AbstractAbstract PDF
Craniopharyngioma accounts for 2~5% of all primary intracranial neoplasms. It may present with a variety of manifestations including neurological, visual, and/or hypothalamic-pituitary dysfunction. Treatment options include radical surgery or radiotherapy, or a combination of these modalities. Craniopharyngioma ablation results in anterior and/or posterior pituitary hormone deficits. Slipped capital femoral epiphysis (SCFE), in which the femoral head slips downward and backward on the femoral neck at the epiphyseal plate, most commonly occurs during the rapid growth phase of puberty. Its actual cause is unknown, but the clinical association between SCFE and endocrine disorders is well known. We report a case of an adult male patient who developed SCFE in association with panhypopituitarism after treatment of a craniopharyngioma.

AbstractAbstract PDF
An angiomyolipoma is a benign mesenchymal neoplasm that typically occurs in the kidney of patients with tuberous sclerosis. Extrarenal angiomyolipomas are uncommon, and the adrenal gland is an extremely rare site for the tumor. An incidental adrenal mass is the usual presentation of an adrenal angiomyolipoma, as most of the tumors are hormonally inactive. Recently we experienced one case of a right adrenal angiomyolipoma that presented with an adrenal incidentaloma. To the best of our knowledge, this is the first case of an adrenal angiomyolipoma described in the Korean medical literature. We report the case with a special emphasis on the differential imaging findings of fat-containing adrenal tumors.

AbstractAbstract PDF
Most patients with hypercalcemia are asymptomatic or they have non-specific symptoms at diagnosis. Yet hypercalcemic crisis is a potentially fatal complication of hyperparathyroidism. Cystic parathyroid adenoma is a rare cause of primary hyperparathyroidism and hypercalcemic crisis. A 52-year-old woman was transferred to our hospital due to her relapsed drowsy mental state and renal insufficiency that occurred in course of her management for intracranial hemorrhage with manitol. The total serum calcium was 16.2 mg/dL and the intact parathyroid hormone was 546 pg/mL. Neck computed tomography showed a 3.1 x 1.8 cm sized cystic mass on the right thyroid lower pole. 99mTc-labelled sestamibi scintigraphy showed no significant uptake. In addition to prompt saline infusion and loop diuretics, the patient was given pamidronate to lower the serum calcium, and she was improved to an alert mental state with normal renal function. Surgical excision of the parathyroid cyst was performed. A histological examination confirmed a cystic parathyroid adenoma. The levels of plasma PTH and serum calcium were normalized after resection.

BACKGROUND
PAD-SEARCH (Peripheral Arterial Disease-Screening and Evaluation of diabetic patients in Asian Regions Characterized by High risk factors) is the first international study to investigate the prevalence of peripheral arterial disease (PAD) in Asian type 2 diabetic patients and to demonstrate the relationships between the putative risk factors and PAD in this population. METHODS: A total of 6,625 type 2 diabetic patients (2,873 males and 3,752 females aged 50 and older) were enrolled in PAD-SEARCH in Korea, China, Taiwan, Hong Kong, Indonesia, Thailand and Philippines from October 2003 to March 2004. The Fukuda vascular profile VS-1000(TM) was used to determine the ankle-brachial index (ABI) and the brachial-ankle pulse wave velocity (baPWV). RESULTS: The mean patient age was 63.7 +/- 8.2 years and the mean duration of diabetes was 10.3 +/- 8.0 years. 1,172 (17.7%) subjects were diagnosed as PAD by the ABI (< or = 0.9). Subjects with PAD had a significantly longer duration of diabetes or hypertension, a higher HbA1c level and a significantly lower mean BMI than did the non-PAD subjects. In terms of the lipid profiles, triglyceride was the only significant variable. Notably, the mean ABI and baPWV in the females were significantly poorer than the age matched males for the in subjects with a normal ABI. However, the mean ABI and baPWV in males were significantly poorer than those of the age matched females for the subjects with PAD. On the multivariate analysis, gender, age, BMI, smoking status, duration of diabetes and a previous history of cerebrovascular disease were identified as the independent risk factors of PAD. CONCLUSION: These findings suggest that PAD is a common complication in Asian type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for Asian diabetic patients with high risk factors.

AbstractAbstract PDF
A goiter is among the most common presenting symptoms of patients with thyroid diseases and is usually caused by intrinsic thyroid problems. While direct invasion of the trachea by aggressive thyroid tumors is a well-known phenomenon, the reverse situation, that is, a primary tracheal neoplasm invading by direct extension into the thyroid gland, presenting with a goiter is very rare. Here, a case of a tracheal adenoid cystic carcinoma(ACC), presenting with a diffuse goiter, is reported. A 47-year-old woman presented with slowly growing anterior neck swelling. A physical examination showed a diffuse firm goiter. The patient was euthyroiditic, and serum negative for thyroid autoantibodies. Thyroid ultrasonography and neck CT revealed a doughnut-shaped mass, encircling the trachea and displacing the thyroid anteriorly. Ultrasonography-guided fine needle aspiration(FNA) was compatible with an ACC, and a subsequent surgical resection confirmed the diagnosis. Although the occurrence of a tracheal ACC invading the thyroid is rare, this case highlights the need to be aware of unusual lesions arising in the region of the thyroid. This knowledge will help in making the correct cytological diagnosis when these lesions are sampled by FNA

AbstractAbstract PDF
Carcinoma of the thyroid usually presents as a palpable thyroid mass. However, in rare cases patients with thyroid cancer present with metastases of the cervical lymph node as the initial manifestation. The metastatic papillary tumor in cervical lymph nodes stained positive for thyroglobulin indicates the presence of a thyroid carcinoma, usually in the ipsilateral lobe. We herein report a case of multiple metastases in papillary thyroid carcinoma arising in the lateral aberrant thyroid with no evidence of thyroid carcinoma in the thyroid lobe.

AbstractAbstract PDF
BACKGROUND
Bone mineral density(BMD) is thought to be under genetic control. Polymorphisms at the vitamin D receptor(VDR) gene have recently been shown to contribute to the genetic variability in bone mineral density in Caucasians. However, the relationship between VDR-RFLP(restriction fragment length polymorphisms) and bone mineral density is controversial. METHODS: The VDR-RFLP by BsmI, ApaI, and TaqI were studied in 250(77 premenopausal, 173 postmenopausal) Korean women. Bone mineral densities at the lumbar spine(L2-L4), femoral neck, greater trochanter, and Wards triangle were measured by DEXA(Dual Energy X-ray Absorptiometry; Lunar DPX-L, U.S.A.). RESULTS: There were significant differences in VDR gene allele frequency when compared with those in Caucasians. The BsmI polymorphism was consisted of 0.8% BB homozygotes, 12.4% Bb heterozygotes, and 86.8% bb homozygotes. The ApaI polymorphism was 6.8% AA homozygotes, 42.0% Aa heterozygotes, and 51.2% aa homozygotes, and the TaqI polymorphism was 83.2% TT homozygotes, 16.8% Tt heterozygotes, and 0% tt homozygotes. When these three VDR-RFLP were combined, bbaaTT(51.2%), bbAaTT(29.6%), and BbAaTt(10.0%) were found to be most frequent types. There were no significant relationship between VDR-RFLP and BMD measured at the 2nd to 4th lumbar spine in all subjects. But there were significant relationship between VDR-RFLP and BMD at the proxmial femur in all subjects. Compared with bb or bbaaTT(or bbAaTT), women with the Bb or BbAaTt genotypes had significantly lower bone mineral densities at the proximal femur in all subjects. When we restricted the analysis to early postmenopausal women less than 10 years since menopause, these findings were more pronounced. CONCLUSION: These results suggest that VDR-RFLP may affect on BMD at the proximal femur in Korean women. However, the frequencies of B, A, and t alleles are very low in Korean women compared to those of Caucasians, further studies will be needed, with larger sample sizes.

AbstractAbstract PDF
The impairement of glucose metabolism is frequently associated in hyperthyroidism. The present study was performed to determine the effect of the thyroid hormone excess on insulin sensitivity and on insulin secretory function in vivo. Ten newly diagnosed hyperthyroid patients and fifteen healthy control subjects were subjected to frequently sampled intravenous glucose tolerance tests(FSIGT) after an overnight fast. Insulin sensitivity, represented by the insulin sensitivity index(S_1), was assessed by minimal model analysis of FSIGT data. Insulin secretion was measured by the total area under the insulin curve after glucose load.The results were as follows.1) The K_G values, which represent glucose tolerance, were not different between the hyperthyroid patients and the normals(2.2+-0.3 vs. 2.5+-0.3%/min, p>0.05).2) S_1 was significantly decreased in the hyperthyroid patients in comparison to the normals(7.5+-1.4 vs. 2.6+-0.3X10^-4 min^-1/uU/ml, p<0.05).3) The basal insulin concentration was higher in the hyperthyroid patients than in the normals(8.3+-2.4 vs. 4.6+-0.4 uU/ml, p=0.07). In addition, the insulin secretory response to a glucose load was increased in the hyperthyroid patients as evidenced by the peak plasma insulin level(168.2+-30.4 vs. 89.2+-13.9 uU/ml, p<0.05) and by the total area under the insulin curve(2641.1+-443.2 vs. 1696.7+-204.3 min uU/ml, p<0.05).These results clearly demonstrated that insulin sensitivity was impaired in these newly diagnosed hyperthyroid patients. However, glucose tolerance was maintained by the increased insulin secretion.
