BACKGROUND: The aim of this study was to investigate the factors associated with resolution of hypertension after adrenalectomy in patients with primary aldosteronism. A secondary aim was to describe our use of the contralateral ratio in adrenal venous sampling (AVS) in the setting of suboptimal successful cannulation rates. METHODS: A retrospective review of patients who underwent AVS followed by unilateral adrenalectomy for primary aldosteronism was performed. RESULTS: Complete resolution of hypertension and hypokalemia was seen in 17 of 40 patients (42.5%), while a clinical improvement in hypertension was seen in 38 of 40 (95%). Shorter duration of hypertension, mean aldosteronoma resolution score (ARS), and a high ARS of 3 to 5 were associated with resolution of hypertension after adrenalectomy (P=0.02, P=0.02, and P=0.004, respectively). Of the individual components of ARS, only a duration of hypertension of ≤6 years was associated with resolution of hypertension after adrenalectomy (P=0.03). CONCLUSION: A shorter duration of hypertension was significantly associated with resolution of hypertension after adrenalectomy in patients with primary aldosteronism.

Prader Willi Syndrome (PWS) includes complex endocrinological issues because of the hypothalamic and pituitary dysfunction which include obesity and diabetes, as well as behavioural issues. Other important aspects of PWS, such as hepatosplenomegaly are sometimes neglected. We present a case of diabetic ketoacidosis precipitated by torsion of a wandering spleen in a 22-year-old woman with PWS and type 2 diabetes mellitus. The pancreatic tail was involved in the torsion leading to hyperamylasaemia and pancreatitis. The splenic torsion and pancreatitis were initially treated conservatively with resolution of symptoms. A year later, she had another 2 episodes of severe abdominal pain due to worsening splenic torsion which subsided with conservative management. She subsequently underwent an elective splenectomy which revealed an enlarged and wandering spleen, with 720 degrees torsion of the long splenic pedicle.

INTRODUCTIONThe aim of this study was to identify patient characteristics and risk factors associated with in-hospital mortality of patients with pulmonary tuberculosis (PTB) requiring intensive care unit (ICU) management.

METHODSA retrospective chart review was conducted of all patients with active PTB admitted to the ICU at Singapore General Hospital, Singapore, between January 2005 and December 2010.

RESULTSThere were 2,155 patients with active PTB diagnosed, of whom 83 (3.9%) patients were admitted to the ICU, but eight were excluded because their admission to the ICU was unrelated to PTB. The most common comorbidities were diabetes mellitus (n = 23, 30.7%) and immunocompromised host (n = 25, 33.3%). A few (n = 4, 5.3%) of the patients had HIV coinfection. A majority (n = 67, 89.3%) of patients required mechanical ventilation and the mean duration of mechanical ventilation was 8.05 ± 14.43 days. Mean duration of ICU stay and hospital stay were 10.23 ± 15.8 days and 33.7 ± 50.7 days, respectively. In-hospital mortality was 62.7% (n = 47), and 36 of these patients died while in the ICU (ICU mortality, 48.0%). Univariate analysis identified ischaemic heart disease, low albumin, Acute Physiology and Chronic Health Evaluation score, disseminated intravascular coagulation, shock and multiorgan failure as significantly associated with mortality. Multivariate analysis showed that low albumin on the day of ICU admission was the only significant independent predictor of death (p = 0.033).

CONCLUSIONIn-hospital mortality from active PTB requiring ICU admission was 62.7%, and low albumin was an independent predictor of mortality in this study.
