The impact of sexual dysfunction (SD) is distressing to many male patients with pituitary adenomas which affect both physical and psychological health. The research explored to identify risk factors affecting sexual function and the prognosis of male patients with pituitary adenomas. Two hundred and fifty-four male patients, who aged between 18 and 60 (mean ± s.d.: 44.16 ± 10.14) years and diagnosed with pituitary adenomas, were retrospectively analyzed. One hundred and fifty-nine patients (62.6%) complained of SD prior to surgery. The mean International Index of Erectile Function (IIEF-5) in patients with giant adenomas was 16.13 ± 2.51, much smaller than those with microadenomas or macroadenomas (P < 0.05). All the patients showed significant improvement in terms of erectile dysfunction (ED) following surgery (P < 0.05). In addition, complete resection achieved a higher degree of SD relief than partial resection. The incidence of SD in functioning pituitary adenomas (FPAs) was much higher than that in nonfunctioning pituitary adenomas (NFPAs) (P < 0.05). In addition, compared with NFPAs, males with prolactinomas (82.8%) had the higher prevalence of SD and significantly improvement following surgical intervention (P < 0.05). An inverse relationship was identified between decreasing testosterone levels and increasing incidence of SD before surgery (P < 0.05). There was no significant difference between 6 months and 12 months after surgery in serum testosterone level (P > 0.05). Our results indicated that surgical therapy could be optimized for improvements in SD and that testosterone levels can be used as a sensitive indicator to predict the recovery rate of sexual function in patients with pituitary adenomas following surgery and the serum testosterone level will stay stable in 6 months after surgery.

BACKGROUND/AIMS: An association between serum uric acid and cancer risk has been noted over the past few decades. There is ongoing debate about whether hyperuricemia represents an independent risk factor for colorectal neoplasm. We investigated the association between serum uric acid and prevalence of colorectal adenoma considering numerous confounding factors. METHODS: A cross-sectional study was performed with individuals who underwent a routine health check-up examination, including a screening colonoscopy and blood chemistry. The association between serum uric acid and prevalence of colorectal adenoma was estimated from the results of a logistic regression analysis. RESULTS: Of the 1,066 participants, 402 had colorectal adenoma (37.7%). In univariate models, the prevalence of colorectal adenoma was higher in participants in the fourth quartile uric acid level, compared to those in the first quartile uric acid level (OR, 1.67; 95% CI, 1.17-2.42; p=0.004). However, no significant association was detected between serum uric acid and prevalence of colorectal adenoma in multiple logistic regression analysis. A number of metabolic syndrome components exhibited a strong association with the prevalence of colorectal adenoma in the multivariate model (OR, 3.46 for highest vs. lowest; 95% CI, 1.30-9.20; p=0.021). Moreover, serum uric acid was strongly associated with metabolic syndrome-associated variables, including waist circumference, fasting blood glucose, systolic blood pressure, diastolic blood pressure, triglyceride, and high-density lipoprotein. CONCLUSIONS: Uric acid is not an independent risk factor for colorectal adenoma but is a risk indicator for metabolic syndrome-related colorectal adenoma.

OBJECTIVE: To investigate the clinical manifestation, diagnosis, treatment of parathyroid occupying lesions. METHOD: The clinical data of 26 patients with parathyroid occupying lesions between January 2003 and October 2012 at Dalian Central Hospital were retrospectively analyzed. RESULT: There were 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma, 13 cases of parathyroid cysts in this study. All the cases,except 13 cases of cysts, are accompanied by symptoms of hyperparathyroidism. The symptoms were as follows:26 cases of neck lump, 11 cases of osteoporosis/osteitis fibrosa cystica,9 cases of urinary symptom, 8 cases of digestive symptom. Serum calciumion level and serum parathyroid hormone(PTH) level were examined qualitatively before operation. Ultrasonography, CT, MRI were used in diagnosing and locating parathyroid occupying lesion before operation. 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts with preoperative and postoperative diagnosis coincidence rate was 0 (0/2), 91% (10/11), 69% (9/13). All patients were treated with operation. 2 cases of parathyroid cancer survived with out recurrence during follow up for 17 months and 27 months after operation. 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts were treated with operation,achieved complete remission and the outcome was no recurrence. CONCLUSION There lack of specific clinical symptoms of parathyroid occupying lesions,neck lump are common manifestations. Examination of serum calcium and PTH level together with ultrasonography, CT, MRI, 99mTc-MIBI is helpful to diagnose parathyroid occupying lesions. Parathyroid cancer preoperative diagnosis is difficult . Parathyroid occupying lesions determine the diagnosis depends on pathology. Surgery should be done as primary treatment.

BACKGROUND/AIMS: Helicobacter pylori is a well known precursor to gastric cancer and gastric mucosa-associated lymphoid tissue lymphoma. This study was to determine whether H. pylori was associated with colorectal neoplasms in Korean subjects undergoing routine checkup. METHODS: A total of 10,082 subjects underwent routine checkups from January 2004 to April 2005. A H. pylori IgG test and stool occult blood test were included in the routine checkup program. Colonoscopy was performed if the stool occult blood test was positive or under subject request. Patients who underwent colonoscopy and had histologically confirmed cases of colorectal neoplasms were designanted as the subject group and those without as the control group. RESULTS: Of the 10,082 subjects, 597 had full colonoscopy. The results identified 9 colorectal carcinomas and 118 adenomas. H. pylori seropositivity was identified in 6 (66%) subjects with colorectal carcinoma, 81 (68.6%) with colorectal adenoma and 248 (52.8%) controls. Subjects having colorectal neoplasms had a significantly higher H. pylori seropositivity rate compared with the controls (OR 1.94, 95% CI 1.28-2.95). This remained significant after adjusting for age, sex, body mass index, HbA1c and total cholesterol (OR 1.90, 95% CI 1.23-2.93). Patients with distal neoplasms also had a significantly higher H. pylori seroposivity rate (OR 1.88, 95% CI 1.17-3.01) which persisted after multivariate adjustment (OR 1.79, 95% CI 1.10-2.94). CONCLUSIONS: Subjects with colorectal neoplasms present an increased H. pylori seroprevalence compared with controls.

Primary aldosteronism (PA) is a frequent cause of secondary hypertension and is amenable to surgical intervention when it is caused by aldosterone-producing adenoma (APA). Many patients, however, continue to require antihypertensive medications to control their blood pressure after adrenalectomy. The aim of this study was to determine the preoperative factors that predict clinical outcomes after adrenalectomy in patients with APA. We studied 27 patients (mean age 45+/-4 yr) who had APA and underwent unilateral adrenalectomy between December 1995 and September 2008 at our institution. Clinical and biochemical data were evaluated at baseline and after a mean follow-up of 51.8+/-47.0 months (range, 6-159). At the end of the follow-up, 16 patients (59.3%) were considered to experience "complete resolution" without postoperative medications, whereas 7 patients (25.9%) "improved" with medications and 4 patients (14.8%) were "uncontrolled." Three factors (< or =2 antihypertensive medications [P=0.007], duration of hypertension <6 yr [P=0.002], and serum aldosterone <350 pg/mL [P<0.001]) were the predictive for complete resolution in univariate analysis. Multivariate regression analysis showed that serum aldosterone level (<350 pg/mL) was the single most important factor that predicted complete resolution after surgery (P<0.001). The best preoperative clinical factor that predicted resolution of postoperative hypertension after adrenalectomy is serum aldosterone level (<350 pg/mL).

It has been suggested that the patients with Cushing's disease secondary to pituitary macroadenomas (>10 mm) have higher basal adrenocorticotropic hormone (ACTH) levels, which are less suppressible on high-dose dexamethasone suppression tests (HDDST). We compared the clinical and biochemical characteristics of patients with macroadenomas (N=7) and microadenomas (N=23) who were diagnosed at Samsung Medical Center in Korea between 1996 and 2006. Basal morning plasma ACTH levels were 101.5+/-23.2 pg/mL for macroadenoma patients and 83.6+/-11.1 pg/mL for microadenoma patients (mean+/-SEMs) (p=0.44). Morning serum cortisol levels were 26.8+/-3.2 microgram/dL for macroadenoma patients and 29.5 +/-2.9 microgram/dL for microadenoma patients (p=0.77). The proportion of patients who showed suppressibility on HDDST was almost identical in the two groups (71.4% [5/7] for macroadenoma patients vs. 72.7% [16/22] for microadenoma patients, p=1.00). Furthermore, the remission rate with trans-sphenoidal surgery was similar between the two groups (100% [5/5] for macroadenoma patients vs. 73.3% [11/ 15] for microadenoma patients, p=0.53). Thus, tumor size is not a major determinant of hormone secretion or clinical outcomes in patients with Cushing's disease.

BACKGROUND/AIMS: Recent studies implicated inflammation playing an important role in the occurrence and advancement of colorectal cancer. Colorectal adenoma as the representative precursor lesion of colorectal cancer has meaningful association with inflammation. Accordingly, the purpose of this study was to evaluate the association between serum C-reactive protein (CRP) levels and the risk of colorectal adenoma METHODS: This study was undertaken on 5,487 subjects (3,478 men and 2,009 women) who underwent colonoscopy at the Health Promotion Center in Kangbuk Samsung Hospital and Samsung Medical Center. The subjects were allocated into 3,505 normal control subjects and 1,982 patients with colorectal adenoma. The mean level of CRP was compared between the two groups, and the correlations with other variables were analyzed by multiple regression analysis. Also, the risk of colorectal adenoma according to CRP level and difference of CRP level according to the characteristics of adenomas were analyzed. RESULTS: There was no significant difference in serum CRP level between normal and colorectal adenoma group. After adjusting for the clinically significant variables of colorectal adenoma, multiple logistic regression analysis of the risk of colorectal adenoma according to the CRP level (<1, 1-3, >3) and the CRP level according to characteristics of adenomas showed no significant difference. CONCLUSIONS: An inflammatory marker, CRP is not a risk factor for colorectal adenoma development.

We describe here the case of a 39-year-old woman with a cortisol-producing adrenal adenoma and she presented with endometrial hyperplasia and hypertension without the specific characteristics of Cushing's syndrome. The patient had consulted a gynecologist for menometrorrhagia 2 years prior to her referral and she was diagnosed with endometrial hyperplasia and hypertension. Her blood pressure and the endometrial lesion were refractory despite taking multiple antihypertensives and repetitive dilation and curettage and progestin treatment. On admission, the clinical examination revealed mild central obesity (a body mass index of 22.9 kg/m2, a waist circumference of 85 cm and a hip circumference of 94cm), but there was no hirsutism and myopathy. She showed impaired glucose tolerance on an oral glucose tolerance test. The biochemical hypercortisolemia together with the prolactin and androgen levels were evaluated to explore the cause of her anovulation. Adrenal Cushing's syndrome was confirmed on the basis of the elevated urinary free cortisol (454 microgram/24h, normal range: 20-70) with a suppressed ACTH level (2.0 pg/mL, normal range: 6.0-76.0) and the loss of circadian cortisol secretion. A CT scan revealed a 3.1 cm, hyperechoic, well-marginated mass in the left adrenal gland. Ten months post-adrenalectomy, the patient had unintentionally lost 9 kg of body weight, had regained a regular menstrual cycle and had normal thickness of her endometrium.

OBJECTIVETo investigate the experience on diagnosis and treatment of multiple adrenal aldosterone-producing adenomas (APA).

METHODSEighteen cases of multiple adrenal APA were analyzed retrospectively, which were admitted from October 1992 to April 2006.

RESULTSAdrenalectomy was performed for 4 cases of unilateral synchronous multiple APA, which were discovered with three adenomas by 3D-CT; bilateral tumor resection was performed for 6 cases of bilateral synchronous multiple APA. There were 8 cases of bilateral metachronous multiple APA, including 2 cases of ipsilateral recurrent adrenal APA after adrenal tumor removal, which underwent tumor resection. Another 6 cases were contralateral APA following adrenalectomy due to adrenal APA, and underwent tumor resection. After operation, the adrenal function seemed to be normal, and no recurrence had been found on follow-up.

CONCLUSIONSUnilateral multiple synchronous APA require adrenalectomy. Tumor resection should be performed for bilateral or asynchronous APA, and it is very important to preserve healthy adrenal tissue as much as possible. 3D-CT has much value on diagnosis of small APA, unilateral multiple synchronous APA and ipsilateral recurrent adrenal APA.
