BACKGROUND: Esmolol has been applied to lower myocardial oxygen consumption and creates a quieter operative field by reducing systemic blood pressure and heart rate but can cause a certain amount of hemodynamic instability during minimally invasive direct vision coronary artery bypass graft (MIDCAB). The aim of this study was to compare the hemodynamic differences between two methods; inducing hypotension and bradycardia between esmolol infusion alone, and concomitant use of neostigmine during MIDCAB anesthesia. METHODS: Twenty MIDCAB patients were randomly allocated into two groups, group E (n = 10) receiving esmolol 0.3 mg/kg/min, group EN (n = 10) receiving esmolol 0.2 mg/kg/min and neostigmine 1.0 mg for induced hypotension and bradycardia during coronary anastomosis. The hemodynamic parameters were evaluated 10 minutes after induction of anesthesia (T1), 10 minutes after beginning of operation (T2), 5 minutes before the end of anastomosis (T3) and 10 minutes after the end of anastomosis (T4). Data were analyzed by ANOVA test for intragroup comparisons, and by T-test for intergroup comparisons with significance set at a P value of < 0.05. RESULTS: Heart rate significantly decreased at T3 in both groups and more in group EN. Systolic blood pressure decreased at T3 in both groups and there were no group differences but more episodes of extreme hypotension in group E. The cardiac index significantly decreased at T3 in both groups and more in group E. There was a small but significant increase in pulmonary capillary wedge pressure at T3 and T4 in group E and no change of central venous pressure in both groups. CONCLUSION: Concomitant use of neostigmine during esmolol infusion produces more reliable induced hypotension and bradycardia than esmolol infusion alone for MIDCAB anesthesia in terms of prevention of myocardial ischemia and easiness of anastomosis technique.

Open tracheostomy has been indicated for patients who require prolonged mechanical ventilation or respiratory care in order to avoid lots of complications during long-term endotracheal intubation. Because there are a number of disadvantages and serious complications in standard open tracheostomy, a simpler, safe and minimally invasive procedure such as percutaneous dilatational tracheostomy (PDT) and translaryngeal tracheostomy (TLT) were introduced as an appropriate procedure that can be administered at bedside. In terms of prevention of complications, minimal invasive tracheostomy techniques are more advisable for post open heart surgery patients. After two failed attempts at respirator weaning, we experienced a successful TLT for a 71-year-old male patient with intractable post CABG pneumonia post-op 15 days in an intensive care unit. During and post-TLT courses were not eventful. The cannula was removed 2 weeks after TLT and the patient was subsequently discharged to ward.

The transforaminal epidural injection (TFEI) has been preferred in many cases because it can deliver the injected dose of medication closer to the nerve root and better facilitate ventral epidural flow compared to other methods. However, in patients with deformities not demonstrated on fluoroscopic imaging, the needle may enter unwanted locations. We treated two cases of intradiscal injection of contrast dye, during the TFEI, in patients with lumbar disc herniation.

Intraaortic balloon counterpulsation (IAB) has been shown to prolong survival in the critically ill cardiac patients. Originally developed for use in the patients with cardiogenic shock, the indications have been expanded. But despite technical advances, the complication rate associated with IAB remains high. The most commonly reported complications include damage to the femoral artery and distal embolization. Other reported major complications are balloon rupture, limb loss, bleeding, systemic infection and bowel infarction. We report a patient complicated by ischemic colitis causing stenosis and intestinal obstruction after IAB insertion.

OBJECTIVES: Neurobiological models for obsessive-compulsive disorder(OCD) have consistently implicated prefrontal-striatal circuits in the pathophysiology of this disorder. But, prior studies have inconsistently found alteration in caudate and frontal lobe volumes in patients with OCD. This study was undertaken in the hope that semi-automated linear transformation methods would elucidate the morphometric differences of various parts of brain between OCD and normal control group. METHODS: Thirteen patients meeting the DSM-IV criteria for OCD, and 9 psychiatrically normal comparison subjects participated in the study. 3-D brain MRIs using Spoiled gradient-recalled (SPGR) sequence were acquired for each subjects. After spatially normalized according to Talairach and Tournoux's coordinates, the gray and white matters were segmented by semiautomated methods using fuzzy algorithm. Each lobal volumes was measured according to Talairach and Tournoux's coordinates, and the region of interests of caudate nuclei was manually traced. The frontal lobe was divided into 3 subregions; dorsolateral prefrontal cortex, orbital frontal cortex, mesial frontal cortex accoring to the coordinates and Broadman's cytoarchitectonics. RESULTS: Only the volume of left and right frontal gray matter showed a significant difference between OCD and normal subjects. In OCD, the frontal gray matter volume was increased in tendency. There's no difference in laterality and no coorelation with clinical severities. CONCLUSION: Findings of increased frontal gray matter volumes in patients implicate a structural abnormality of these brain regions in the pathophysiology of OCD. The increased frontal gray matter volumes reflect a epiphenomena due to increased cerebral blood flows and metabolic rates before the structural changes may occur.

Breast surgery is a common procedure performed in women. Many women who undergo breast surgery suffer from ill-defined pain syndromes. A nerve block is used in the treatment of the acute and chronic pain, but the effectiveness of the treatment has been limited because of its short duration. Recently, the advent of pulsed radiofrequency lesioning (PRF) has proved a successful treatment for chronic refractory pain involving the peripheral nerves. We experienced a case of a 52-year-old female patient complaining of chronic breast neuropathic pain after breast reduction, which was relieved after PRF lesioning of the 4th thoracic spinal nerve and its root.

N-acetylglucosamine kinase (GlcNAc kinase or NAGK) is a ubiquitously expressed enzyme in mammalian cells. Recent studies have shown that NAGK has an essential structural, non-enzymatic role in the upregulation of dendritogenesis. In this study, we conducted yeast two-hybrid screening to search for NAGK-binding proteins and found a specific interaction between NAGK and dynein light-chain roadblock type 1 (DYNLRB1). Immunocytochemistry (ICC) on hippocampal neurons using antibodies against NAGK and DYNLRB1 or dynein heavy chain showed some colocalization, which was increased by treating the live cells with a crosslinker. A proximity ligation assay (PLA) of NAGK-dynein followed by tubulin ICC showed the localization of PLA signals on microtubule fibers at dendritic branch points. NAGK-dynein PLA combined with Golgi ICC showed the colocalization of PLA signals with somal Golgi facing the apical dendrite and with Golgi outposts in dendritic branch points and distensions. NAGK-Golgi PLA followed by tubulin or DYNLRB1 ICC showed that PLA signals colocalize with DYNLRB1 at dendritic branch points and at somal Golgi, indicating a tripartite interaction between NAGK, dynein and Golgi. Finally, the ectopic introduction of a small peptide derived from the C-terminal amino acids 74-96 of DYNLRB1 resulted in the stunting of hippocampal neuron dendrites in culture. Our data indicate that the NAGK-dynein-Golgi tripartite interaction at dendritic branch points functions to regulate dendritic growth and/or branching.

Activity-dependent dendritic translation in CNS neurons is important for the synapse-specific provision of proteins that may be necessary for strengthening of synaptic connections. A major rate-limiting factor during protein synthesis is the availability of eukaryotic translation initiation factor 4E (eIF4E), an mRNA 5'-cap-binding protein. In this study we show by fluorescence in situ hybridization (FISH) that the mRNA for eIF4E is present in the dendrites of cultured rat hippocampal neurons. Under basal culture conditions, 58.7 +/- 11.6% of the eIF4E mRNA clusters localize with or immediately adjacent to PSD-95 clusters. Neuronal activation with KCl (60 mM, 10 min) very significantly increases the number of eIF4E mRNA clusters in dendrites by 50.1 and 74.5% at 2 and 6 h after treatment, respectively. In addition, the proportion of eIF4E mRNA clusters that localize with PSD-95 increases to 74.4 +/- 7.7% and 77.8 +/- 7.6% of the eIF4E clusters at 2 and 6 h after KCl treatment, respectively. Our results demonstrate the presence of eIF4E mRNA in dendrites and an activity-dependent increase of these clusters at synaptic sites. This provides a potential mechanism by which protein translation at synapses may be enhanced in response to synaptic stimulation.
