Introduction Androgen deficiency in aging men has attracted much medical interest. Most studies on androgen deficiency have been conducted in Caucasian populations, and data from other ethnicities are lacking. Aim To evaluate the prevalence of and risk factors for androgen deficiency and symptomatic androgen deficiency in Taiwanese men over 40 years old. Methods From August 2007 to April 2008, a free health screening was conducted by a medical center in Kaohsiung, Taiwan, and 819 men participated in this health screening. All participants completed a health questionnaire, received a detailed physical examination, and blood samples were drawn between 8:00 and 12:00 am. Main Outcome Measures Serum total testosterone (TT), albumin, and sex hormone-binding globulin levels were measured. The level of free testosterone (FT) was calculated. Clinical symptoms of androgen deficiency were assessed using the Androgen Deficiency in the Aging Male (ADAM) questionnaire. Results Seven hundred thirty-four men who met the inclusion criteria (mean age 57.4 ± 6.7 years; range: 43–87 years) were included in this study. The prevalence of androgen deficiency was 24.1% based on the criterion of TT level < 300 ng/dL, and 16.6% based on the criterion of both TT < 300 ng/dL and FT < 5 ng/dL. The prevalence of symptomatic androgen deficiency was 12.0%. Both prevalence of androgen deficiency and symptomatic androgen deficiency increased with age. Older age, obesity, and diabetes mellitus were independent risk factors for androgen deficiency and symptomatic androgen deficiency. Conclusions In a sample of aging Taiwanese men, a substantial proportion had androgen deficiency and symptomatic androgen deficiency, and the prevalence increased with age. Older age, obesity, and diabetes mellitus were independent risk factors for androgen deficiency and symptomatic androgen deficiency. Those potentially modifiable risk factors like obesity and diabetes mellitus should be prevented to maintain normal testosterone levels during aging in men.
Schwannoma of the adrenal gland is extremely rare. Here, we report a 49-year-old patient with an adrenal tumor noted incidentally by abdominal ultrasonography while undergoing regular health examination. Retroperitoneal laparoscopic adrenalectomy was performed and the schwannoma was diagnosed by histologic findings and immunohistochemistry. Five months after surgery, the patient remained well and without evidence of recurrence or metastasis.
Spontaneous perirenal hematoma is relatively uncommon but may be life threatening. There are some challenges in early diagnosis due to the lack of specific presentations. We report a case of spontaneous perirenal hematoma in a patient who had histories of systemic lupus erythematosus, hypertension, and uremia with hemodialysis, and initially presented with non-specific flank pain. Dizziness and unstable vital signs were noted in the emergency room. Computed tomography and abdominal ultrasonography revealed a large perirenal hematoma over the left retroperitoneal cavity. The patient received conservative treatment without surgical intervention and had an uneventful recovery.
Actinomycosis is a rare, chronic suppurative infection caused by the Gram-positive anaerobic filamentous bacterium, Actinomyces israeli. In most cases, the diagnosis is made postoperatively because of its unusual clinical presentation. Abdominal actinomycosis is the second most common site of the disease and may mimic abdominal cancer, inflammatory bowel disease or diverticulitis. The abdominal-pelvic form of this disease mostly results from the prolonged use of an intrauterine device. We report a rare case of combined intra- and extra-abdominal actinomycosis mimicking urachal tumor that was diagnosed by computed tomography, which presented as two tender abdominal palpable masses following long-term intrauterine device use. The disease was confirmed by postoperative histopathologic examination, which revealed sulfur granules microscopically, and was successfully treated by complete surgical resection following a period of appropriate antibiotic treatment.
The purpose of this study was to determine the influence of metabolic syndrome (MS) and serum testosterone in patients with erectile dysfunction (ED) and their possible association. A total of 103 men with ED were enrolled. The International Index of Erectile Function (IIEF) questionnaire was used to assess erectile condition. MS was defined according to the criteria formulated by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) and the International Diabetes Federation (IDF). The mean age of the study population was 57.5 +/- 10.7 years, with an average IIEF of 14.7 +/- 6.7. The age and prevalence of MS using the NCEP ATP III criteria, but not the IDF criteria, were significantly different between mild and moderate/severe ED patients (p = 0.031 and 0.009, respectively). The percentage of hypertension (78.6% vs. 36.2%; p < 0.001) and raised fasting glucose levels (46.4% vs. 19.1%; p = 0.004) were significantly higher in the moderate/severe ED group, and both differences remained significant in multivariate analysis (p = 0.001 and 0.042, respectively). In addition, serum testosterone levels were significantly lower in ED patients with MS (p = 0.002). In summary, the presence of MS is associated with more severe ED. Among the components of MS, elevated blood pressure and fasting blood glucose were independent risk factors. NCEP ATP III criteria seem to correlate better with the degree of ED than the IDF definition. Our results also indicate that MS is associated with a lower testosterone level in patients with ED.
Fat-containing tumors of the kidneys are not uncommon, but primary intrarenal lipomas are extremely rare, with only 19 documented cases reported to date. In most cases, total nephrectomy is performed. We report on a 71-year-old man with the complaint of epigastralgia. Series image studies revealed a high fat-containing tumor with low vascularity arising from the lower pole of the left kidney. We performed partial nephrectomy, and the subsequent pathology report revealed a pure lipoma.
Uric acid urolithiasis develops from various causes. To investigate the clinical and biochemical presentation of patients with uric acid urolithiasis, a retrospective study was designed. A total of 46 cases were enrolled between January 2004 and December 2005. The compositions of the stones were analyzed by infrared spectrophotometry. There were 39 males (84.8%) and seven females (15.2%), with a mean age of 61.5 +/- 10.6 years and mean body mass index (BMI) of 26.7 +/- 3.1 kg/m2. The stone location was kidney in 10 (21.7%), ureter in 22 (41.8%), and bladder in 14 (30.5%). Multiple stones were diagnosed in 36 patients (78.3%). Pre-existing comorbidities included diabetes mellitus in 11 patients (23.9%), hypertension in 23 (50%), gout in 13 (28.2%), and benign prostatic hyperplasia in 14 (30.4%). Mean serum creatinine and uric acid was 1.6 +/- 0.6 mg/dL and 7.6 +/- 1.8 mg/dL, respectively. There were 27 patients (58%) with creatinine > 1.4 mg/dL. The mean urinary pH was 5.42 +/- 0.46. Patients with uric acid urolithiasis were predominantly male, older, with higher BMI, multiple stone presentation, with lower urinary pH, and hyperuricemia. Exacerbation of the renal function should also be of concern because of the high proportion of patients with renal insufficiency diagnosed in this study.
Ureteral obstruction secondary to endometriosis is relatively uncommon. We present a 49-year-old female (gravida 3, para 2, abortion 1), who was identified as suffering from right hydronephrosis while undergoing her regular health examination. Retrograde pyelography demonstrated a partial obstruction of the right ureter in the distal third. She underwent ureteroscopy and biopsy to remove a right ureteral tumor. Histological examination confirmed ureteral endometriosis. During follow-up at the obstetrics and gynecology outpatient department, an abdominal echo was detected that revealed a right endometrioma (size, 7.5 x 4.8 x 5.5 cm) on the ovary. As a result, a total hysterectomy and bilateral salpingo-oophorectomy was performed. Although the patient had right residual hydronephrosis, the creatinine level improved to 1.2 mg/dL during follow-up.
