BACKGROUNDHemolytic anemia, elevated liver enzymes and low platelet count (HELLP) syndrome is a severe obstetric complication which usually resolves in most patients after delivery.

METHODSWe report a rare case of aggravation of HELLP syndrome after delivery.

RESULTSThe patient underwent the treatment for HELLP syndrome, including glucocorticoid therapy. The symptoms of HELLP syndrome reappeared and became more severe than before the termination of pregnancy. The patient also had severe and persistent hypoproteinemia, hyponatremia and hypocalcemia.

CONCLUSIONSHELLP syndrome is an acute and critical obstetric syndrome which can have heterogeneous presentations and variable prognosis. We should be fully aware of the diverse clinical characteristics of this condition.

OBJECTIVE: lo discuss the inmtluence of different thyroidectomy on perioperative blood calcium concentration. METHOD: Total number of patients was 240. These patients of thyroid tumors were recruited. Clinical and follow-up datum were retrospective analyzed. RESULT: Patients were divided into four groups by different operative methods. Group one was patients taken one-side thyroidectomy, group two taken one-side lymph node dissection plus, group three taken two-sides thyroidectomy,and group four taken one or two sides lymph node dissection plus. Group two was easier to become hypocalcemia and their calcium concentration decreased more remarkably, compared with group one. Patients taken two-sides thyroidectomy had the familiar outcome. CONCLUSION Patients taken lymph node dissection were easier to become hypocalcemia, compared with patients only taken thyroidectomy.

The metabolic alterations caused by hyperaldosteronism are being increasingly recognized and have generated considerable interest among the medical fraternity. Hyperaldosteronism is suspected to have a pivotal role in the patho-physiology of congestive cardiac failure where it has been studied extensively. But its effects on calcium metabolism, parathyroid metabolism and renal handling of calcium are less well described. Recent experimental models have shed light into the roles played by previously unknown mechanisms in causing these metabolic alterations. We hereby report a case of primary hyperaldosteronism due to adrenal adenoma (Conn's syndrome) who presented with a myriad of clinical features including symptomatic hypocalcemia, significant weight loss along with uncontrolled hypertension for a prolonged period before eventually detected to have primary hyperaldosteronism. Surgical removal of the causative tumor resulted in prompt disappearance of all the symptoms and signs and regain of lost weight.

Dilated cardiomyopathy (DCM) is usually an idiopathic disease with a poor prognosis. Hypocalcemia is a rare and reversible cause of DCM. Here, we report a 50-year-old female with DCM, induced by idiopathic hypoparathyroidism, that improved after treatment with calcium.

BACKGROUND/AIMS: The aim of this study is to measure the difference of ionized calcium between heparinized whole blood and serum. METHODS: We recruited 107 maintenance hemodialysis (HD) patients from our hospital HD unit. The clinical and laboratory data included ionized calcium in serum and in whole blood (reference, 4.07 to 5.17 mg/dL). RESULTS: The level of ionized calcium in serum was higher than that in whole blood (p < 0.001). Bland-Altman analysis showed that difference for ionized calcium was 0.5027. For the difference, the nonstandardized beta was -0.4389 (p < 0.001) and the intercept was 2.2418 (p < 0.001). There was a significant difference in the distribution of categories of ionized calcium level between two methods (kappa, 0.279; p < 0.001). CONCLUSIONS: This study demonstrates that whole blood ionized calcium is underestimated compared with serum ionized calcium. Positive difference increases as whole blood ionized calcium decreases. Therefore, significant hypocalcemia in whole blood ionized calcium should be verified by serum ionized calcium.

OBJECTIVETo explore a cosmetic incision in the neck dissection for differentiated thyroid carcinoma.

METHODSAn extended collar incision was used for neck dissection in 82 consecutive patients with thyroid carcinoma from May 1999 to December 2006. The incision was designed to start as a conventional thyroid collar incision, and then to extend it along the skin crease to the anterior border of trapezium, so to avoid the vertical limb of conventional hockey stick incision. There were 60 females and 22 males in this series, with a median age of 40.5 years (range, 10 to 80 years). Ninety-six procedures of neck dissection were performed in 82 patients, including one radical neck dissection, one type I modified neck dissection, 8 type II modified neck dissections, and 86 type III modified neck dissections.

RESULTSThe average time of anesthesia was 197 minutes. The average dissected lymph nodes were 37.5, with average metastasis in 8.8 nodes. Eight patients (9.8%) developed complications related to neck dissection. The follow-up period in these patients were 1 to 96 months with a median follow-up time of 23 months. Cervical recurrence was found in only one patient (1.2%). Neither death nor distant metastasis was observed in this series.

CONCLUSIONIt is feasible to perform a modified neck dissection for differentiated thyroid cancer through the extended collar incision. The preliminary results show that the above described incision is not only oncologically safe, but also offers a cosmetic benefit for the patient with thyroid carcinoma.

BACKGROUNDParathyroid hormone deficiency or resistance may cause hypocalcemia with related symptoms and signs. Lifelong treatment of calcium combined with vitamin D or its metabolites is always necessary for these patients. Here we reported a prospective and open-label trial to investigate the efficacy and safety of domestic-made calcitriol in treatment of hypocalcemia caused by hypoparathyroidism or pseudohypoparathyroidism.

METHODSTwenty-four patients with confirmed hypoparathyroidism or pseudohypoparathyroidism aged (36.5 +/- 11.0) years old were studied. Among them, 16 patients had idiopathic hypoparathyroidism, 2 had pseudohypoparathyroidism and 6 had hypoparathyroidism secondary to cervical surgery. Serum calcium levels were lower than 1.88 mmol/L. Oral calcitriol was administered twice or three times with elemental calcium 1.2 g per day. All patients were followed every 4 weeks throughout the 12-week period. Dose adjustments of calcitriol were based on serum and urinary calcium levels and symptoms of hypocalcemia.

RESULTSTwenty patients were included by the end of this study. Muscular weakness, cramps, extremity paresthesia, Chovestek's sign and Trousseau's sign were relieved in 76.9%, 100%, 94.4%, 93.3% and 78.9% of patients, respectively. Serum calcium, plasma ionized calcium and serum phosphorus levels were (1.54+/-0.25) mmol/L, (0.64+/-0.10) mmol/L and (2.00+/-0.46) mmol/L at baseline, and reached (2.20+/-0.20) mmol/L, (0.95+/-0.06) mmol/L and (1.68+/-0.25) mmol/L (P<0.01) at the 12th week of treatment, respectively. Eighty percent of patients were assessed as effective and 20% as partly effective. Three, four and eight patients had hypercalciuria at the 4th, 8th and 12th week of treatment, respectively, which were reduced by thiazide diuretics. The final dose of calcitriol was (1.09+/-0.50) microg/d.

CONCLUSIONSCalcitriol combined with calcium can be used in treatment of hypocalcemia caused by hypoparathyroidism or pseudohypoparathyroidism effectively and safely. Serum and urinary calcium levels should be monitored during the course of the therapy.

Primary hyperparathyroidism due to ectopic parathyroid adenomas can pose diagnostic and management challenges, especially when imaging studies have localised the lesions to different sites. We report a case of symptomatic hypercalcaemia due to a mediastinal parathyroid adenoma. Ultrasonography identified a nodule posterior to the right thyroid gland. However, computed tomography and technetium-99m sestamibi scintigraphy revealed an ectopic parathyroid adenoma located in the anterior mediastinum. The adenoma was successfully removed through a median sternotomy. However, postoperatively, the patient developed prolonged symptomatic hypocalcaemia, possibly due to suppression of the normal parathyroid gland function, although the presence of concomitant hungry bone syndrome was possible. The histopathology of the mediastinal mass was consistent with a parathyroid adenoma.
