ABSTRACT

BACKGROUND: Syndrome of inappropriate antidiuretic hormone secretion can be caused by arginine-vasopressin-producing tumors or enhanced arginine vasopressin secretion from the posterior pituitary gland due to central nervous system disorders and intrathoracic diseases. CASE PRESENTATION: A 53-year-old Asian man was hospitalized with complaints of tremor and hiccups. Laboratory examination revealed findings suggestive of hypotonic hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion. The patient did not complain of headache or photophobia, and showed no signs of meningeal irritation. Positron emission tomography-computed tomography revealed 18F-fluoro-deoxy-glucose accumulation along the cervical spinal cord, based on which the patient was diagnosed as having aseptic meningitis. The hyponatremia was treated successfully by fluid restriction, and optimum plasma sodium concentration was maintained by tolvaptan administration. CONCLUSIONS: This case underscores the need to consider the possibility of mild meningitis as the cause of syndrome of inappropriate antidiuretic hormone secretion in patients without other identifiable cause.

ABSTRACT

Electrolyte disorders are relatively frequent and potentially serious complications after pituitary surgery. Both DI (diabetes insipidus) and SIADH (syndrome of inappropriate antidiuresis) can complicate and prolong hospital and intensive care unit stay, and the latter may even be preventable. We aim to assess the incidence of both electrolyte disorders and their risk factors. From a prospective registry of patients who underwent endoscopic transnasal transsphenoidal surgery (TSS) for pituitary adenoma, patients with postoperative DI and SIADH were identified. Univariable and multivariable statistics were carried out to identify factors independently associated with the occurrence of either DI or SIADH. A total of 174 patients were included, of which 73 (42%) were female. Mean age was 54 years (range 20-88). During postoperative hospital stay, 13 (7.5%) patients presenting with DI and 11 (6.3%) with SIADH were identified. Patients who developed DI after surgery had significantly longer hospital stays (p = 0.022), as did those who developed SIADH (p = 0.002). Four (2.3%) patients were discharged with a diagnosis of persistent DI, and 2 (1.1%) with the diagnosis of SIADH. At the last follow-up, 5 (2.9%) patients presented with persistent DI, while none of the patients suffered from SIADH. Younger age (odds ratio (OR) 0.97, 95% confidence interval (CI) 0.94-1.01, p = 0.166) and pituitary apoplexy (OR 2.69, 95% CI 0.53-10.65, p = 0.184) were weakly associated with the occurrence of DI. We identified younger age (OR 0.96, 95% CI 0.92-0.99, p = 0.045) and lower preoperative serum sodium (OR 0.83, 95% CI 0.71-0.95, p = 0.008) as independent risk factors for SIADH. Although we found a weak association among age, pituitary apoplexy, and the occurrence of DI, no independent predictor was identified for DI. For postoperative SIADH however, lower age and preoperative serum sodium were identified as significant predictors. None of these findings were sufficiently supported by preexisting literature. Both electrolyte disorders are exquisitely hard to predict preoperatively, and further research into their early detection and prevention is warranted.

ABSTRACT

Syndrome of inappropriate antidiuretic hormone (SIADH) is the most common cause of hyponatraemia. There are many causes of SIADH, but investigation tends to focus around the most common causes-particularly diseases of the brain and lung, malignancy and medication-induced SIADH [Ellison and Berl (2007, The Syndrome of Inappropriate Antidiuresis. N Engl J Med., 356, 2064-72]. We describe a case of SIADH secondary to atonic bladder in an 83-year old woman, which was discovered on MRI of the abdomen, performed for further characterisation of a known pancreatic lesion. Insertion of a urinary catheter alleviated retention and resulted in prompt resolution of hyponatraemia. This is an under-recognised cause of this common condition, with important implications for investigation and management.

ABSTRACT

The triphasic response of pituitary stalk injury has previously been described in a minority of patients following intracranial surgery, however, this phenomenon can also occur after traumatic brain injury. We present the case of a 20-year-old male who experienced the triphasic response of pituitary stalk injury (central diabetes insipidus, syndrome of inappropriate antidiuretic hormone and central diabetes insipidus again) after striking his head on a concrete curb. His history and presentation highlight the importance of recognising the distinctive symptoms of each individual stage of pituitary stalk injury, and using the appropriate diagnostic tools and therapies to guide further management.

ABSTRACT

The symptoms of chikungunya virus (CHIKV) infection include fever, headache, muscle aches, skin rash, and polyarthralgia, characterized by intense pain, edema, and temporary functional impairment. This is the first report of encephalitis caused by CHIKV infection associated with an atypical presentation of syndrome of inappropriate antidiuretic hormone secretion, evolving to cognitive impairment and apraxia of speech.

ABSTRACT

Patients with cavernous carotid fistulas (CCFs) can present with pituitary hypoperfusion and hypopituitarism; however, there are no previous reports of pituitary or hormonal abnormalities developing after CCF embolisation in an asymptomatic patient. We describe a patient with no hormonal abnormalities who developed syndrome of inappropriate antidiuretic hormone (SIADH) secretion after CCF embolisation. The patient had bilateral indirect CCFs, which were completely embolised via a transvenous approach, and was neurologically stable postoperatively and discharged. In the subsequent 2 weeks the patient was readmitted twice for acute hyponatraemia and a tonic-clonic seizure. Laboratory studies revealed severe SIADH. Clinical status and sodium levels improved after treatment. One year later the patient was weaned off all medications and remained neurologically stable. SIADH may be a delayed phenomenon after CCF embolisation. Given the proximity of embolised vessels to the pituitary's vascular supply, CCF treatment may result in flow disturbance, ischaemia and hormonal abnormalities.

ABSTRACT

A 77-year-old man was admitted to our hospital complaining of general fatigue. Serum sodium was 116 mEq/l and serum antidiuretic hormone (ADH) was elevated. Radiologic examination revealed nodules in the brain as well as in both adrenal glands. Based on the findings of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET), we had considered that the cause of the hyponatremia was syndrome of inappropriate secretion of antidiuretic hormone (SIADH) due to active extrapulmonary tuberculosis. Against our expectations, the patient's condition got worse just after he began antituberculous therapy; we finally diagnosed Addison's disease by additional hormonal tests. His condition recovered immediately with the administration of high-dose hydrocortisone, and the tuberculous lesions became smaller with antituberculous medications. Although tuberculous Addison's disease has been decreasing markedly in recent years, we have to consider the possibility of adrenal insufficiency when hyponatremia is observed in patients with active tuberculosis or those having a past history of tuberculosis.

ABSTRACT

We report a case of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) after the patient had received several anti-cancer drugs, including vincristine (VCR), in a patient with myeloid antigen positive acute lymphoblastic leukemia (My(+)-ALL). A 53-year-old woman presented at the hospital complaining of high-grade fever and general lassitude. Further examination revealed that she had My(+)-ALL. On admission, she was treated with anti-cancer drugs, including VCR. On day 24, after the first administration of VCR, a conscious disturbance suddenly occurred and she was diagnosed with SIADH. A plain head CT scan showed a low density lesion through the gray matter to the white matter in the bilateral occipital lobe, as well as diffuse swelling of the cerebrum. This was not seen on the follow up CT scan, and we concluded that it had been a transient abnormal finding due to SIADH. She achieved complete remission after induction chemotherapy and 3 added courses of consolidation chemotherapy. VCR was also administered 4 times in the second consolidation chemotherapy, but hyponatremia did not occur. This case suggests that a head CT scan is a useful procedure for the diagnosis and monitoring of SIADH, and that VCR may still be used in a patient who has suffered from VCR-induced SIADH.

ABSTRACT

We present an infant who underwent endoscopic third ventriculostomy due to symptomatic hydrocephalus secondary to aqueductal stenosis. This is the first reported case of inappropriate secretion of antidiuretic hormone complicated by hyponatriemia and seizures following endoscopic surgery. The possibility of such a neuroendoscopic complication should alert neurosurgeons and close observation of serum electrolytes is highly recommended in the acute postoperative period, particularly in infants.

ABSTRACT

Schwartz-Bartter syndrome often results from lung cancer. With reference to two observations, attention is drawn to the value of opacifying the superior vena cava for demonstrating the tumor. This investigation also allows guided biopsy sampling as exemplified in the second observation. Vascular investigations seem all the more useful as small-cell carcinoma often develops outside the bronchi and are often inaccessible by endoscopy.
