Non-islet-cell tumor induced hypoglycemia:one case report and literature review / 中华内分泌代谢杂志

A patient with severe hypoglycemia due to insulin-like growth factor ( IGF)-IIsecreted by a giant solitary fibrous tumor of the pleura ( SFTP) was investigated through comprehensively reviewing his medical history and clinical records. The patient had severe hypoglycemia accompanied with significantly decreased serum insulin level. A solitary fibrous tumor of the pleura was found, and right pneumonectomy removed this giant tumor. Two years after the operation, the patient was fit and well with no further hypoglycemia episodes. Non-islet-cell tumor hypoglycemia should be considered in patients who have hypoglycemia episodes accompanied with significantly decreased serum insulin level.

Adrenal Castleman′s disease:A case report and literature review / 中华内分泌代谢杂志

Objective To raise the awareness of adrenal Castleman′s disease by analyzing the clinical features and management of a patient with adrenal Castleman′s disease. Methods A case of adrenal Castleman′s disease of our hospital was retrospectively analyzed, including clinical feature, laboratory findings, pathology, treatment, and follow-up. All the data and pertinent literatures were reviewed and analyzed. Results An incidentaloma measuring 4. 8 cm × 6. 3 cm in the right adrenal gland was observed in a 30-year-old men in a ultrasonography examination performed due to a medical check-up. Laboratory analysis showed that the lesion was not hyperfunctioning. The patient subsequently underwent an exploratory laparotomy. Pathological examination revealed retroperitoneally localized Castleman′s disease of the hyaline vascular type. Conclusion Adrenal Castleman′s disease is a rare cause of lymph node hypertrophy, and it is necessary to keep in mind the possibility of its occurrence and take it into consideration in the differential diagnosis of any solitary, heterogeneous, and hypervascular retroperitoneal mass. The proper cooperation between the clinician and pathologist allows early diagnosis and suitable therapy.

OBJECTIVE@#To evaluate the therapeutic results of endoscopic orbital decompression for thyroid-associated ophthalmopathy.@*METHOD@#The records of nine patients (twelve orbits) received endoscopic orbital decompression for thyroid-associated ophthalmopathy were analyzed for changes in visual acuity, intraocular pressure, proptosis, corneal ulceration and movement. The follow-ups ranged from two months to thirty-six months.@*RESULT@#Twelve orbits (100%) had improvement in visual acuity (range 0.1-0.7). Ten orbits (83.3%) decreased in intraocular pressure (range 0.2-21.4 mm Hg). Eight orbits (66.70%) decreased in proptosis (one-five mm). The orbit with corneal ulcer was healed after decompression. Diplopia was cured in one of four patients.@*CONCLUSION@#Endoscopic orbital decompression is a safe and effective procedure for the treatment of thyroid-associated ophthalmopathy.

The value of bilateral inferior petrosal sinus sampling in the differential diagnosis of ACTH-dependent Cushing's syndrome / 中华内分泌代谢杂志

Objective To evaluate the values of bilateral inferior petrosal sinus sampling ( BIPSS),high dosage dexamethasone suppression test (HDDST) and pituitary image in the differential diagnosis of ACTH-dependent Cushing's syndrome. Methods Totally 87 patients with confirmed pathological diagnosis were recruited in the study.All received the procedure of BLPSS,HDDST,and pituitary MRI with dynamic enhancement.The diagnostic performances of three differential diagnosis methods in ACTH-dependent Cushing's syndrome were evaluated.Results Seventy-eight patients were diagnosed as cases of pituitary ACTH adenoma,and the remaining 9 were confirmed cases of ectopic ACTH syndrome due to the thymic carcinoid.The sensitivity and specificity of HDDST,pituitary MRI,and BIPSS for the diagnosis of ACTH-dependent Cushing's syndrome were 82.1％ and 100％,79.5％ and 44.4％,92.3％ and 100％,respectively.In Cushing's disease,the diagnostic accuracy was 83.9％ with HDDST,77.0％with pituitary MRI,and93.1％ with BIPSS.In those patients with Cushing's disease,the coincidence of lateralization was 83.9％ with BIPSS and 64.5％ with MRII.Conclusion BIPSS was better than the other two methods in differential diagnosis of ACTH-dependent Cushing's syndrome.Compared with the pituitary MRI,the concordant rate of BIPSS in lateralization of the tumor is higher,and it is more reliable.

Multi-detector-row CT findings of ACTH-independent macronodular adrenal hyperplasia / 中华内分泌代谢杂志

ObjectiveTo explore the characteristics multi-detector-row computed tomography (MDCT)findings of ACTH-independent macronodular adrenal hyperplasia ( AIMAH ).Methods The un-enhanced and contrast-enhanced MDCT features in 24 patients ( 14 males and 10 females) with clinically confirmed AIMAH were retrospectively assessed for the morphology and enhancement patterns.ResultsThe adrenal glands were involved bilaterally in all of the 24 cases( 100％ ).24 patients had massively enlarged multinodular adrenal glands.Nodules were( 1.79 ± 1.02) cm (0.50 ～ 3.85 cm),which usually distorted and completely obscured the normal adrenal glands.The enlarged adrenal glands were still retained the adreniform contour,showed characteristic ginger-like.22 of the 24 ( 91.7 ％ ) hyperplastic nodular glands demonstrated mild homogeneous enhancement.Calcification was revealed in 1 adrenals ( 1/24,4.2％ ).Conclusion MDCT reveals the characteristic morphology and CT attenuation in AIMAH.Combined with its clinical presentation and biochemical findings,AIMAH is able to be diagnosed with high specificity and accuracy on MDCT.

Imaging diagnosis of primary aldosteronism / 中国实用内科杂志

Primary aldosteronism (PA) is a common cause for secondary hypertension.The diagnosis of PA is based on clinical and biochemical features of suspects.Imaging diagnosis plays an important role in differential diagnosis between the two main causes of PA:aldosterone-producing adenoma and idiopathic hyperaldosteronism.CT is especially important for the localization and differential diagnosis of PA.Adrenal venous sampling is invasive,but it is the most reliable approach for determining the causes of PA.

Adrenal venous sampling in the differential diagnosis of primary aldosteronism / 中国实用内科杂志

Objective To study the value of adrenal venous sampling (AVS) in the differential diagnosis of primary aldosteronism (PA).Methods Fourteen patients (11 adenoma and 3 adrenal hyperplasia) clinically diagnosed as PA were examined with AVS for measurement of plasma aldosterone and cortisol levels.Selectivity of AVS was assessed by the aldosterone level in each adrenal vein and in the infrarenal inferior vena cava plasma.The data were compared with CT and postoperative pathologic result.Results The diagnosis of adenoma by AVS in 9 (9/11) cases was in accordance with the postoperative pathologic findings.The diagnosis of hyperplasia by AVS in all 3 cases was in accordance with CT scanning result.Conclusion AVS should be selected to distinguish the PA without overt occupational lesion in CT scanning.

Diagnosis and surgical treatment of parathyroid carcinoma / 中国普通外科杂志

Objective To evaluate the diagnosis and surgical treatment of parathyroid carcinoma (PTC). Methods Clinical data of 8 PTC cases were analyzed retrospectively. Results PTC accounted for 5. 7% of patients with primary hyperparathyroidism (PHPT) in our hospital. There were 4 men and 4 women. Male patients had younger mean onset age compared with female patients. The disease history of PTC was shorter than PHPT of benign causes. Six patients were admitted for acute hypercalcemia. Seven patients complained of palpable neck mass. Calcium level was 3.75?0.34 mmol/L,and PTH level was 1429.47?841.75 pg/ml. Frozen section established diagnosis in only one case. Four patients underwent radical en bloc resection. Other 4 cases received routine simple parathyroidectomy, 3 patients developed recurrence in 12 - 18 months postoperatively. Conclusions Acute hypercalcemia is common in PTC. Frozen biopsy diagnosis is not satisfactory. An initial en bloc resection of tumor and adjacent structures contributes most to the prognosis.

Genetical diagnosis in a congenital achondroplasia family / 中华内分泌代谢杂志

Objective To indentify the gene mutation of fibroblast growth factor receptor 3 (FGFR3) gene in a Chinese family with congenital achondroplasia (ACH). Methods The genomic DNA from 2 clinically diagnosed ACH patients and the other 4 members from the same family was prepared for PCR. The products of PCR were purified and then sequenced directly. Results Two patients with ACH in this family showed G-A transition mutation at nucleotide 1138 as heterozygotes. Conclusion The G-A transition mutation at nucleotide 1138 in transmembrane domain of FGFR3 gene seems to be the pathologic cause of this Chinese family with ACH.

Ectopic ACTH syndrome caused by thymus carcinoid / 中华内分泌代谢杂志

Objective To increase the awareness of ectopic ACTH syndrome in patients with thymus carcinoid. Methods Clinical manifestations, especially atypical presentation of ectopic ACTH syndrome, laboratory findings and imaging data (chest X-ray and CT, etc.) in 6 patients were analysed. Results In all 6 patients, the thymus tumors removed were pathologically proved to be thymus carcinoid. Conclusion Patients having typical manifestations of Cushing′s syndrome with hypokalemia, edema, proteinuria and equivocal result of dexamethasone inhibition test, should be considered as ACTH syndrome. And thymus carcinoid seems to be the cause of the disease.
