PURPOSE: Delirium is a common and serious neuropsychiatric complication among terminally ill cancer patients. We investigated risk factors related to the development of delirium among hospice care patients. METHODS: Between May 2011 and September 2012, we included patients who were mentally alert and had no psychiatric disease or drug addiction at the hospice ward of two local hospitals. Among them, participants who had been diagnosed with delirium by two doctors according to the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders-4th edition) criteria were grouped as Delirium Group. We analyzed results of psychometric and other laboratory tests performed at the time of patient's admission - psychometric tests included cognitive function (mini-mental status examination, MMSE), depression (Beck Depression Inventory, BDI), anxiety, and insomnia (Insomnia Severity Index, ISI). Logistic regression analysis was used to compare delirium and the related factors. Cox's proportional hazard model was performed using significant factors of logistic regression analysis. RESULTS: Of the 96 patients who met the inclusion criteria, 41 (42.7%) developed delirium. According to the logistic regression analysis, primary cancer site, cognitive impairment (MMSE<24), depression (BDI> or =16), and insomnia (ISI> or =15) were significant factors related to delirium. Among the four factors, depression (OR 5.130; 95% CI, 2.009~13.097) and cognitive impairment (OR 5.130; 95% CI, 2.009~13.097) were found significant using Cox's proportional hazard model. CONCLUSION: The development of delirium was significantly related to depression and cognitive impairment among patients receiving hospice care. It is necessary to carefully monitor depression and cognitive function in hospice care.

Pheochromocytomas are neoplasms of the adrenal gland that are derived from chromaffin cells. One of the most important features of this tumor is that it can synthesize and release catecholamines such as norepinephrine and epinephrine. Due to this, arterial hypertension is one of the most common manifestations of the tumor. Although arterial hypertension is a substantial risk factor for aortic dissection, aortic dissection is actually a rare manifestation of pheochromocytoma. Here, we report a patient with pheochromocytoma who presented with acute type B aortic dissection.

BACKGROUND: Topoisomerase II (topo II) is a major target of anthracyclines and epipodophyllotoxins for anticancer treatment. The expression of topo II is low in drug resistant cell lines. High levels of glutathione S-transferase (GST)pi have been associated with emergence of cell lines resistant to alkylating agents or adriamycin. METHODS: By immunostaining with paraffin embedded bone marrow tissues, the expression of topo II alpha and GSTpi was investigated in 51 patients with acute myeloid leukemia (AML), and the relation of topo II alpha and GSTpi expression to treatment response in 29 patients with AML following induction chemotherapy was also evaluated. RESULTS: Topo II positive cells varied from less than 1% to 60% of leukemic cells and 20 (39.2%) were negative for topo II (positive cells<10%). Treatment response following chemotherapy was not related to topo II. 26 (51.0%) were positive for GSTpi. GSTpi expression was related to treatment resistance of the patients following chemotherapy. In the patients who showed both topo II alpha negative and GSTpi positive, the frequency of treatment resistance following chemotherapy was high. CONCLUSIONS: This study suggests that immunostaining of topo II alpha and GSTpi with the bone marrow paraffin sections of AML patients can be useful to predict the treatment response following chemotherapy and that further study including more patients with prospective study may substantiate topo II alpha and GSTpi as multidrug resistant markers.

OBJECTIVE: To quantitatively evaluate the side- and level-specific change of the multifidus muscle in unilateral radicular pain caused by lumbar disc herniation using magnetic resonance imaging (MRI).METHOD: Sixty-nine patients with L4-5 disc herniation who underwent electrodiagnostic study and spine MRI were enrolled and divided into the radiculopathy group (n=30) and the control group (n=39) according to the presence of L5 radiculopathy. The radiculopathy group was subdivided into the paraspinalis group (n=12) and the limb group (n=18) according to whether or not paraspinalis muscle was denervated. The cross-sectional area (CSA) and signal intensity (SI) of the multifidus muscle were measured bilaterally at L4-5 and L5-S1 middle intervertebral levels on axial T2-weighted MRI.RESULTS: There was no significant difference in the CSA of the multifidus muscle between the radiculopathy group and the control group. In the radiculopathy group, multifidus SI was greater than the control group on the affected side and below the level of herniation (p=0.015). In the subgroup comparison, affected side L5-S1 multifidus SI was significantly different between the paraspinalis group and the control group (p=0.001), but not between the limb group and the control group (p>0.05).CONCLUSION: Our findings suggest that quantitative measurement of multifidus SI may be indicative of the location of nerve root compromise through side- and level- specific changes.

Clay-shoveler’s fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler’s fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2∼T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler’s fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler’s fracture is one possibility to consider.

Benign teratomas of the thyroid are very rare in adolescence and adults. In this review, we report a case of 14-year-old Korean girl with huge neck mass. She presented with anterior neck enlargement and compression symptom which was rapidly aggravated in 2 months. In physical examination, enlarged and firm right thyroid lobe was palpated and laboratory test of thyroid function was normal. In ultrasonography, right lobe was mainly occupied with a solid nodule size of 44×23×25 mm, showing markedly inhomogeneous hypoechogenicity. As fine needle aspiration cytology was non-diagnostic, lobectomy was done. Histological examination demonstrated that the tumor is benign thyroid teratoma composed of tissue from all three germ layers. When large thyroid nodule is detected in adolescence and malignancy could not be ruled out, final diagnosis should be made with surgical resection. And we should at least attentive for possibility of teratomas when ultrasonographic findings are suspicious.

BACKGROUND: Diabetic cardiac autonomic neuropathy (CAN) is one of the important complications of diabetes. It is characterized by reduced heart rate variability (HRV). METHODS: In this randomized, double-blind, placebo-controlled, multicenter trial, 75 patients were randomly assigned to one of two groups. One group (n=41) received α-lipoic acid (ALA) at an oral dose of 600 mg/day for the first 12 weeks and then 1,200 mg/day for the next 12 weeks. The other group (n=34) received placebo treatment for 24 weeks. CAN was assessed by measuring HRVs in people with diabetes. RESULTS: Most of the baseline measures for HRVs were similar between the ALA and placebo groups. Although there were no statistically significant HRV changes in the ALA group compared to the placebo group after 24 weeks of trial, we found a positive tendency in some of the HRV parameters of the ALA group. The standard deviations of normal-to-normal RR intervals in the standing position increased by 1.87 ms in the ALA group but decreased by −3.97 ms in the placebo group (P=0.06). The power spectrum of the low frequency (LF) band in the standing position increased by 15.77 ms² in the ALA group, whereas it declined by −15.04 ms² in the placebo group (P=0.08). The high frequency/LF ratio in the upright position increased by 0.35 in the ALA group, whereas it declined by −0.42 in the placebo group (P=0.06). There were no differences between the two groups regarding rates of adverse events. CONCLUSION: Although a slight improvement tendency was seen in HRV in the ALA group, there were no statistically significant HRV changes in the ALA group compared to the placebo group after 24 weeks of trial. However, the high oral dose of ALA was well-tolerated.

Levels of soluble interleukin-2 receptor alpha (sIL-2Ralpha) are known to increase in the sera of patients with certain malignancies, including malignant lymphoma. This study aimed to assess the clinical significance of the sIL-2Ralpha level in non-Hodgkin's lymphoma (NHL). We used ELISA to measure the sIL-2Ralpha levels in 48 newly diagnosed and untreated patients with NHL and evaluated the correlation between the sIL-2Ralpha levels and clinical characteristics and the International Prognostic Index (IPI). We monitored serum sIL-2Ralpha in 7 patients to compare the changes in their clinical progress with these levels. High levels of serum sIL-2Ralpha (> or =2,000 U/mL) correlated well with parameters defining the high risk group according to the IPI, i.e., high tumor burden at diagnosis (stage III+IV) and lactate dehydrogenase > or =472 U/L. The levels were also associated with B symptoms, bone marrow involvement, and poor response to therapy. The sIL-2Ralpha level decreased during complete remission and was elevated during disease progression or relapse. A high level of sIL-2Ralpha was significantly associated with a low survival rate. These results suggest that serum sIL-2Ralpha might be useful as a biomarker for evaluating the prognosis of patients with NHL at the time of diagnosis and during therapy. A well-controlled, large-scale study is needed to clarify the clinical significance of sIL-2Ralpha in specific groups of NHL.

OBJECTIVE: To investigate the presence of cranial neuropathy in patients with platinum-analogue chemotherapy using electrodiagnostic evaluations. METHODS: Thirty-nine patients whose chemotherapy was completed within a month and 40 control subjects were enrolled in the study. Electrodiagnostic evaluation was performed using sensory and motor nerve conduction studies and blink reflex studies, in addition to the two-point discrimination test. RESULTS: The chemotherapy group had significantly longer latencies of bilateral R1 responses (left p<0.001; right p<0.001) and greater distance in two-point discrimination (p<0.001) compared to the control group. In the subgroup with peripheral polyneuropathy, the left R1 (p=0.01), both R2i (left p=0.02; right p=0.03) and the left R2c (p=0.02) were prolonged relative to those without the polyneuropathy, and both R1 (left p<0.001; right p<0.001), R2i (left p=0.01; right p=0.03), and the left R2c (p=0.01) were prolonged relative to the controls. On the other hand, the subgroup without the polyneuropathy showed only prolongation of both R1 (left p=0.006; right p<0.001) relative to the controls. CONCLUSION: In the present study, comparison of blink reflex and two-point discrimination showed the likelihood of subclinical cranial neuropathy following platinum-analogue chemotherapy. Cranial neuropathy caused by platinum agents was more profound in patients with peripheral polyneuropathy and may be dependent on the cumulative dose of the drug. The blink reflex may be of value in detecting subclinical cranial neuropathy in patients undergoing platinum-analogue chemotherapy.
