An autopsy case of Shy-Drager syndrome preceded by urinary disturbance for over 20 years was reported. A 43-year-old woman was admitted to our hospital because of urinary disturbance and orthostatic hypotension. At the age of 19 she developed urinary disturbance with polyuria and retention. These symptoms were getting worse with years, and at the age of 33 she was diagnosed to have neurogenic bladder of uninhibited type. During her hospital course her symptom became worse, and by the age of 42 she showed marked dysarthria, disturbance of smooth pursuit eye movement, Horner's syndrome, marked rigidity and tremor of four extremities, generalized hyperreflexia, marked limb and truncal ataxia, neurogenic bladder and orthostatic hypotension. Serial brain CT scan revealed progressive brain stem and cerebellar atrophy with clinical course. Severe autonomic nervous system dysfunctions were also documented. She died of respiratory failure at the age of 43. On autopsy, brain stem and cerebellum showed marked atrophy macroscopically. Microscopically marked depletion of neuron was seen in the substantia nigra, pontine nuclei, inferior olive, Purkinje cells, the intermediolateral column of spinal cord and Onuf's nucleus of S2. Although numerous cases of Shy-Drager syndrome have been reported in the past, there is no case which developed this syndrome after urinary disturbance of over 20 year's duration. We should be alert to observe the cases with longstanding urinary disturbances in order to not overlook degenerative disorders as exemplified in this case.

Diabetes mellitus develops in about 10% of acromegalic patients, usually secondary to insulin resistance caused by growth hormone excess. Diabetic ketoacidosis is a result of relative insulin deficiency and is a rare feature of acromegaly. Here, we present one case of this disorder. A 57-year-old man came to the emergency room due to 2 weeks of dizziness. He also had polyuria, polydipsia, nausea, diplopia, blurred vision and dysarthria. His plasma glucose level was 32.06 mmol/L, plasma osmolarity was 322 mOsm/L, arterial pH was 7.30, level of bicarbonates was 18 mmol/L, urine ketones was 4+, and HbA1c was 14.1%. No specific cause for the development of this metabolic derangement could be found. He displayed clinical features of acromegaly during admission, which was confirmed by an elevated growth hormone level and pituitary macroadenoma shown on magnetic resonance imaging. The patient underwent total transsphenoid tumor removal 2 weeks later; plasma glucose levels became normal thereafter.

A 42-year-old woman, with a 12-year history of bipolar disorder was referred to our department due to tremor, sedation, dysarthria, polyuria and polydipsia. She had been on lithium monotherapy during the last 3 years. On admission, her cognitive status was intact, and neither depression nor euphoria was reported. Lithium plasma levels were 1.6 mEq/L, whereas creatinine and urea levels were 2.8 IU/L and 110 IU/L, respectively. The patient did not take other medications or misused lithium. Lithium was immediately discontinued. Ultrasound scans of the urinary tract were suggestive of bilateral hydronephrosis secondary to bladder contraction and cystoscopy-guided bladder biopsy revealed glandular cystitis a benign tumour into the bladder's wall, which impeded the bladder's contraction leading to hydronephrosis and subsequent toxic lithium plasma levels. The patient was switched to valproate and was referred for surgical excision of the lesion. One year later, she was in good physical and mental health under treatment with valproate (1000 mg/day). This is the first case report of glandular cystitis leading to lithium intoxication by impairing renal function. Acute renal failure leading to lithium intoxication would be possible. However, a thorough imaging, endoscopical and histological study revealed glandular cystitis as the cause of renal impairment. Although physicians are alert about lithium's toxicity and a monitoring of renal function is routinely prescribed, little focus has been made on the integrity of the urinary tract. We suggest that urinary tract imaging should be part of the routine work-up in patients presenting with symptoms and signs of lithium intoxication, since concomitant urinary tract lesions might occasionally be the cause of renal impairment leading to reduced lithium excretion.
