Botulinic toxin (BT) is a new method of lowering intraurethral pressure in symptoms of obstructive voiding in patients with neurogenic dysfunction of the lower urinary tracts (LUT). Transperineal introduction of 100 units of BT type A (botox, Allergan) was used under electromyographic control into the external urethral sphincter of 9 patients (6 males and 3 females) with LUT neurogenic dysfunction aged 17 to 68 years (mean age 37.2 years). Two patients had subnormal detrusor contractility due to myelodysplasia and diabetic polyneuropathy, two other patients--non-incontinent striated urethral sphincter after hemorrhagic stroke and spinal contusion, five patients suffered from detrusor-sphincteral dyssynergia (DSD) resultant from Schmorl's hernia, multiple sclerosis, Charcot-Marie disease and ischemic stroke of the spinal cord. Three patients had cystostomic drainage. The rest of the patients complained of dysuria, three patients performed self-catheterization, mean volume of the residual urine was 170 ml (180-240 ml). In 10 days residual urine was not found in 2 patients with subnormal detrusor contractility and in 4 patients with DSD. Abdominal pressure fell from 75 to 39 cm, on the average. In DSD patients maximal detrusor pressure fell from 59 to 29 cm, on the average. Mean maximal urinary flow rate rose from 4.3 to 9.6 ml/s. In 20 days, on the average, suprapubic fistula healed in all the patients. In a month, therapeutic effect persisted in all the patients. Complications, side effects were not registered. BT treatment to induce adequate urine evacuation in neurological patients is a promising approach in neurourology. Further studies should find answers to questions about regimen of BT introduction, loss of sensitivity, new indications in urology.

The aim of the study was to screen the malignancy in an acromegalic patient group and to determine whether there was any increased risk and the incidence of malignancy and its association with disease characteristics such as duration of disease, latency in diagnosis, and GH and IGF-1 levels. One hundred-five (65 female, 40 male) patients with acromegaly followed and treated at Cerrahpasa Medical School, Endocrinology and Metabolism outpatient clinic between 1983 and 2007 were included in this study. The patients were screened with colonoscopy, mammography, and thyroid and prostate ultrasonography (US). Malignancy was detected in 16 (15%) patients. Thyroid cancer was found in 5 patients (4.7%), breast cancer in 3 (2.8%), colon cancer in 2 (1.9%), lung cancer in 2 (1.9%), cervix cancer in 1 (0.9%), myelodysplastic syndrome (MDS) in 1 (0.9%), cholangiocarcinoma in 1 (0.9%), and multiple endocrine neoplasm (MEN) type 1 in 1 patient (0.9%). Cancer was more common in the male patients (P = 0.046) and high levels of GH increased the risk of cancer development (P = 0.046). In this series, the most commonly detected cancer types were thyroid followed by breast and colon cancers. Although high levels of initial GH seemed to increase the risk of cancer development in acromegalic patients, age, gender, age at the time of diagnosis, duration of disease, and initial IGF-I levels were not associated with cancer development.

We describe the case of a 70-year-old male with acromegaly who developed colon carcinoma and myelodysplastic syndrome (MDS) during the course of acromegaly. MDS progressed to acute myeloid leukemia, but was refractory to chemotherapy. Acromegaly is a rare disorder caused by excessive amounts of growth hormone (GH) primarily secreted by pituitary adenomas. Patients with acromegaly are more prone to develop various malignancies, but there are few reports of hematological malignancies in such patients. In the present case, excessive endogenous GH and insulin-like growth factor-I levels may have altered cell proliferation and thereby affected the oncogenesis and chemosensitivity of both malignancies.
