RESUMO
A total of 71 patients with premature ejaculation (PE) received hydrochloride sertraline treatment for 8 weeks and their serum levels of leptin and 5-hydroxytrytamine (5-HT) were determined.Their ejaculation functions were assessed with intravaginal ejaculation latency time (IELT) and Chinese index of premature ejaculation (CIPE-5) value.The study was compared with 64 normal males as control.The baseline level of leptin in the trial group was obviously higher than the controls (P ＜ 0.05) while the level of 5-HT in the trial group far lower than the controls (P ＜ 0.05).At 8 weeks,the level of leptin dropped while the level of 5-HT rose in the trial group after treatment.Therefore a high serum level of leptin and a low serum level of 5-HT may become biological indicators for PE.
RESUMO
Objective To measure the levels of neutrophil elastase (NE),citric acid and pH in prostatic fluid of patients with prostatitis type Ⅲ.Methods Fifty two patients with prostatitis type ⅢA,98 patients with prostatitis type Ⅲ B and 105 health subjects were enrolled in the study.The levels of NE,citric acid and pH in prostatic fluid were measured ; the expressed prostatic secretion (EPS) routine and bacterial culture were examined,and National Institutes of Health (NIH)-chronic prostatitis symptom index (NIH-CPSI) was evaluated.The data were analyzed by independent samples t-test.Results WBC count,NE and citric acid concentrations,pH in ⅢA group were (17.9 ±5.4)/HP,(898 ±704) μg/L and (14.5 ± 1.7) ng/L,7.60 ±0.43,respectively; those in ⅢB group were (3.9 ±2.2)/HP,(93 ±76) μg/L and (21.9 ±3.8) ng/L,6.71 ±0.25,respectively; those in control group were (3.6 ±2.2)/HP,(86 ±57) μg/L and (22.5 ± 3.9)ng/L,6.48 ± 0.51,respectively.There were significant differences in NE and citrate concentrations,pH value in EPS between Ⅲ A and Ⅲ B patients (t =8.22,16.64 and 13.88,all P ＜0.05),but no difference in NIH-CPSI (t =1.90,P 8 0.05).There were significant differences in WBC count,NE and citric acid concentrations,pH in EPS,NIH-CPSI score between Ⅲ A and control groups (t =18.92,8.47,26.53,18.37 and 32.47,all P ＜ 0.05).There were no differences in WBC count,NE and citric acid concentration and pH value in EPS between Ⅲ B group and control group (t =1.38,1.55,1.02 and 1.21,respectively,all P 80.05),but there was significant difference in NIH-CPSI score between two groups (t =49.46,P ＜ 0.05).In EPS,NE concentration and WBC count were positively correlated with NIH-CPSI (r =0.819 and 0.698,respectively,all P ＜0.01),and citric acid was negatively correlated (r =-0.625,P ＜ 0.01) ; citrate was negatively correlated with WBC count,CPSI and pH value (r =-0.728,-0.644 and-0.817,all P ＜ 0.01).Conclusions The results indicate that the measurements of NE,citric acid and pH in EPS are of significant clinical value in patients with prostatitis type ⅢA and Ⅲ B.
RESUMO
Objective To investigate the interrelationship between leptin and 5-hydroxy tryptamine (5-HT)and their significance in diagnosis of premature ejaculation(PE).Methods 71 cases with lifelong PE(the trial group)and 64 healthy males(the control group)were enrolled in this case-control study.Baseline recording of intravaginal ejaculation latency time(IELT) using a stop watch and Chinese Index of Premature Ejaculation-5 (CIPE-5) were done.The serum leptin and 5-HT levels were determined.Then the trial group were given sertraline hydrochloride for 8 weeks,while the control group were not given any medicine treatment in this period.Reassessment was done after 8 weeks.Results At the baseline,the leptin level in the trial group was obviously higher than the control group(P ＜ 0.05),while 5-HT level in the trial group was far lower than the control group(P ＜0.05).After 8 weeks,the leptin level of the trial group dropped and the difference had no statistical significance with that of the control group(P ＞0.05).5-HT level of the trial group rose to the level very close to that of the control group after the treatment.Conclusion The high level of serum leptin and low level of serum 5-HT were the meaningful biological indicators for PE,which can potentially be applied in PE diagnosis.
RESUMO
Fifty nine patients with premature ejaculation (PE) received sertraline treatment for 8 weeks.The average intravaginal ejaculation latency time (IELT) and the scores of Chinese index of premature ejaculation (CIPE) were evaluated and the fasting serum leptin levels were measured before and after treatment,all the values were compared with those of 64 normal male controls.The serum leptin levels were higher,the IELT and CIPE scores were lower in PE patients than those in normal controls before treatment.After 8 weeks of treatment with sertraline,the levels of serum leptin in PE patients decreased to normal levels,CIPE and IELT increased.The results indicate that serum leptin can be used as a bioindicator for diagnosis of premature ejaculation and assessment of therapeutic efficacy in PE patients.
RESUMO
Two hundred and five patients with a confirmed diagnosis of aldosterone-producing adenomas underwent retroperitoneal laparoscopic operation from January 1999 to December 2009 in our hospital. All cases had hypokalemia and hypertension preoperatively. Of all the cases, 80 received total adrenalectomy and 125 received partial adrenalectomy. Operations were successfully performed in all cases. The time of operation ranged from 15 to 150 min [mean(45 ±13) min] and the volume of bleeding during operation ranged from 10 to 200 ml [mean(25 ±10) ml]. The length of hospital stay ranged from 4 to 9 d [mean(6. 8 ± 1. 2) d]. All patients were followed up for 0. 5 - 2 years (mean 1. 2 years). After operations blood potassium levels returned to normal in all cases, blood pressure returned to normal in 168 cases (82.0% ) . Results indicated that partial or total adrenalectomy with retroperitoneal laparoscopy for aldosterone-producing adenomas was safe and feasible technique.
RESUMO
Objective To explore the diagnosis and treatment of adrenocorticotropin-independent macronodular adrenal hyperplasia (AIMAH). Methods The clinical symptoms, endocrinological and radiological characteristics, treatment modalities, and postoperative clinical course of 12 AIMAH patients were retrospectively reviewed. There were 5 men and 7 women with an average age of 48 years old. Results All cases had some clinical features and biochemical evidence of Cushing's syndrome. The circadian rhythm of serum cortisol was abnormal. Low- and high-dose dexamethasone suppression tests failed to suppress cortisol secretion. CT or MRI scan showed bilateral enlargement of the adrenal glands with multiple macronodules. Bilateral adrenalectomy was performed in three patients and unilateral adrenalectomy combined with contralateral subtotal adrenalectomy was performed in one patient. Seven patients underwent unilateral adrenalectomy of the larger gland. The removed adrenal glands weighted within 8-96 g range and pathologic diagnoses were nodular or adenomatoid hyperplasia of adrenal cortex. The duration of postoperative follow-up was 14 to 124 months. Clinical symptoms of Cushing's syndrome disappeared after surgery in all cases and there was no Nelson's syndrome after bilateral adrenalectomy. Urinary free cortisol and serum cortisol were within normal ranges. No further enlargement of the contralateral gland has been noticed in patients who received unilateral adrenalectomy during the follow-up.Conclusions AIMAH had unique endocrinological and pathological features. Unilateral adrenalectomy appears to be an effective and safe alternative treatment for AIMAH. Bilateral adrenalectomy or unilateral adrenalectomy combined with contralateral subtotal adrenalectomy may be performed if the symptoms had not been improved or recurred after unilateral adrenalectomy.
RESUMO
The clinical data of 21 cases of adrenal ganglioneuroma treated in our hospital from July 1988 to August 2008 were reviewed. The clinical manifestations were: lower back uncomfortableness (9 cases), paroxysmal dizziness (4 cases), central obesity ( 1 case) and 7 cases were discovered incidentally.Five cases were diagnosed pre-operationally and remaining 16 cases were diagnosed post-operationally by pathology. All patients completely recovered after surgery except one, who still had dizziness with high blood pressure. Ultrasonography, CT and MRI examinations are the main diagnostic methods for adrenal ganglioneuroma, and it is confirmed by histopathology, surgical removal of the tumor is the main therapy for the disease.
