Management of adrenal incidentaloma: the role of adrenalectomy may be underestimated.

BACKGROUND: To demonstrate clinical characteristics of adrenal incidentaloma in South China and explore its comprehensive management. METHODS: The clinical data of patients with adrenal neoplasm from Jan 1998 to Dec 2012 were retrospectively analysed. Patients with suspicion of adrenal abnormalities or those in whom adrenal abnormalities were detected in the staging procedures of other cancers were excluded. Most patients with adrenal incidentaloma chose to have adrenalectomy, and some chose surveillance. The relationships between clinical features were analysed with a chi-square test and rank sum test. RESULTS: In total, 634 patients with adrenal incidentaloma were studied. Their age ranged from 17 to 85 years old with a median age of 50 years. Of 478 cases with pathological results, adenoma was the most common tumour (233/478), with 84 cases of pheochromocytoma and 36 cases of adrenocortical carcinoma were 84 and 36. When the tumour size was ≤4 cm, >95 % were benign; when the tumour size was >6 cm, 33 % were malignant. For patients with a tumour size ≤4 cm, 249/376 cases had an adrenalectomy performed. Due to anxiety over a potential malignant transformation and enlargement, most patients (>80 %) under surveillance preferred to undergo adrenalectomy. CONCLUSIONS: Pheochromocytoma and adrenocortical carcinoma were not rare tumours of adrenal incidentaloma, and 4 cm is a good size cutoff to use in the diagnosis of an adrenal incidentaloma. Other than surveillance, laparoscopic adrenalectomy may become the method of choice for management of small adrenal incidentaloma.

Effects of intracoronary injection of nicorandil and tirofiban on myocardial perfusion and short-term prognosis in elderly patients with acute ST-segment elevation myocardial infarction after emergency PCI.

BACKGROUND: This study investigated the effects of the intracoronary injection of nicorandil and tirofiban on myocardial perfusion and short-term prognosis in elderly patients with acute ST-segment elevation myocardial infarction (STEMI) after emergency percutaneous coronary intervention (PCI). METHODS: Seventy-eight STEMI patients with age >65 years who underwent emergency PCI were consecutively enrolled. These patients received conventional PCI and were randomly divided into a control group and a treatment group (n=39 per group). The control group received an intracoronary injection of tirofiban followed by a maintenance infusion for 36 hours after surgery. The treatment group received intracoronary injection of tirofiban and nicorandil, and then intravenous infusion of tirofiban and nicorandil 36 hours after surgery. The following parameters were measured: TIMI grade, corrected TIMI frame count (cTFC), TIMI myocardial perfusion grade (TMPG), ST-segment resolution (STR) rate 2 hours post-operatively, resolution of ST-segment elevation (STR) at 2 hours postoperatively, peak level of serum CK-MB, left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) at 7-10 days postoperatively, and major adverse cardiac events (MACEs) in-hospital and within 30 days post-operatively. RESULTS: Compared with the control group, more patients in the treatment group had TIMI 3 and TMPG 3, and STR after PCI was significantly higher. The treatment group also had significantly lower cTFC, lower infarction relative artery (IRA), lower peak CK-MB, and no reflow ratio after PCI. The treatment group had significantly higher LVEDD and LVEF but lower incidence of MACEs than the control group. CONCLUSION: The intracoronary injection of nicorandil combined with tirofiban can effectively improve myocardial reperfusion in elderly STEMI patients after emergency PCI and improve short-term prognoses.

A rare case of meningoencephalitis by Listeria monocytogenes in systemic lupus erythematosus: case report and review.

Patients with systemic lupus erythematosus (SLE) have a high risk of infection. Central nervous system infection and neuropsychiatric SLE are both major causes of death. It is vital to distinguish between these two conditions to improve prognosis due to the treatment paradigms required for each condition. Here, we report one case of meningoencephalitis by Listeria monocytogenes (LM) in a patient with SLE who presented with fever and developed headache and altered in consciousness in the hospital. The cerebrospinal fluid culture was positive for LM, and magnetic resonance imaging (MRI) findings were suggestive of ependymitis and periventricular white matter lesions. Amoxicillin/sulbactam, trimethoprim-sulfamethoxazole, and rifampicin were administered for 8 weeks. The patient had a relative good recovery without serious neurological sequelae after a follow-up of nearly 2 years. MRI abnormalities also had obvious resolution.
