PURPOSE: We performed this study to compare 1-day group using a 2nd generation cephalsporin with 3-day group for evaluating hospital acquired infection. METHODS: The patients underwent laparoscopic colorectal surgery at Korea University Medical Center Anam Hospital, from August, 2007 to June, 2008. They were randomly allocated to 2 groups: 1-day or 3-day group. A 2nd generation cephalosporin was administered within 1 hour before surgery with 12-hour intervals. In cases of suspected infection, further studies were done to identify infection. RESULTS: The study included 154 patients (1-day group - 78, vs. 3-day group - 76). No differences were noted between the 2 groups in age, body mass index, smoking, diabetes mellitus, corticosteroid-use were noted. Gender (P=0.011) and mean operative time (P=0.047) between the 2 groups were different. The preventive rates of infection were 87.18% in the 1-day group compared with 82.89% in the 3-day group (P=0.456). CONCLUSION: Our prospective randomized control study concluded that there were no differences between the 1-day and 3-day group in hospital acquired infection. We could come to the conclusion that 1-day antimicrobial agent in laparoscopic colorectal surgery would be adequate in preventing infection.

BACKGROUND: Pilomatricoma (PM) is benign follicular tumor composed of the basophilic cells, transitional cells, shadow cells, squamoid cells and keratin filaments/amorphous debris. At present, PM is assumed to differentiate toward hair-forming cells of hair follicles but definite direction is not clear. OBJECTIVES: This study was made in order to investigate the pathways of cell differentiation associated with sudden keratinization in PM. METHODS: In the present study, 19 cases of human PM was histopathologically examined and classified into 4 groups according to the chronological stages. RESULTS: In the chronological stages according to Kaddu's classification, there were 2 cases of early lesion, 6 cases of fully developed lesion, 7 cases of early regressive lesion and 4 cases of late regressive lesion. The basophilic cells changed into the shadow cells or amorphous debris through the transitional cells moving toward the exterior of the PM, as well as toward the interior. As keratinization occurs, some inner basophilic cells which had been located in marginal areas of keratinization lost their tight cell-cell bonding. These cells showed edematous/vesicular and squamoid changes. High molecular weight cytokeratin was expressed in a linear pattern in some early and fully developed lesions. There were fewer layers of basophilic cells between the stroma and squamoid cells/amorphous debris than between the stroma and shadow cells. Ki-67 was expressed strongly both basal and overlying basophilic cells. Apoptotic bodies were detected in most transitional cell layers and some amorphous debris zones. CONCLUSIONS: The present study suggests dual pathways of cell differentiation in PMs. In the sudden keratinization pathway, the basophilic cells, transtional cells, shadow cells, and squamoid cells are suddenly keratinized, and the basophilic cells become early the transitional cells or squamoid cells. Cytoplasmic expressions of Ki-67 and cytokeratin in the basophilic cells show that the basophilic cells differentiate toward the innermost layer of the outer root sheath cells.

BACKGROUND: From our clinical experiences, there are some problems with a paratracheal stellate ganglion block at the 6th cervical level e.g. small changes in blood flow to the upper extremities and more difficulty in differentiating sympathetically-maintained pain from neuropathic pain. This study compared the effectiveness of the classic injection technique and the modified injection technique in paratracheal stellate ganglion block at the 6th cervical level. METHODS: Forty patients were randomly divided into 2 groups. In Group I, the patients underwent a paratracheal stellate ganglion block at the 6th cervical level with 1% mepivacaine 6 ml using the classic injection technique. In Group II, the patients underwent a paratracheal stellate ganglion block at the 6th cervical level with 1% mepivacaine 6 ml using the modified injection technique by applying strong pressure to the cephalad portion of the needle entry point. The skin temperature of the first finger was measured before and after the stellate ganglion block, and the warm sensation on the face and upper extremities, hoarseness and upper extremity paralysis were examined. RESULTS: The increase in skin temperature of the first finger after the procedure was 0.26 +/- 0.22 degrees C in Group I and 0.84 +/- 0.63 degrees C in Group II, which was statistically significant (P < 0.05). There were no significant differences in the warm sensation on the face and upper extremities, hoarseness and upper extremity paralysis between the two groups. CONCLUSIONS: The modified injection technique is more effective in the sympathetic block on the upper extremities than the classic injection technique.

PURPOSE: The aim of this study was to compare the short- and long-term outcomes between stent placement as a bridge to surgery and emergency surgery for obstructive colon cancer. METHODS: Patients who underwent surgery for left colon cancer and rectal cancer with total obstruction from September 2006 to October 2014 were enrolled. Data for the stent placement and emergency surgery groups were compared. RESULTS: Of the 67 patients with total obstruction, 53 patients were treated with stent placement and 14 patients were treated with emergency surgery. Significant differences were observed for surgical approach, type of operation, and combined resection. Use of minimally invasive surgery (MIS) was higher (88.6 vs. 42.9%, p<0.001) in the stent placement (SP) group, and combined resection (5.9 vs. 37.5%, p<0.001) was higher in the emergency surgery (EM) group. In the SP group, resection and anastomosis accounted for the largest proportion (92.5%) and in the EM group, Hartmann's procedure was most common (57.1%) (p<0.001). There were no significant differences in other operative outcomes or in postoperative courses. Five-year overall survival was 96.0 and 77.8% (p=0.311) in the SP and EM groups, respectively. Five-year disease-free survival for local recurrence in the SP and EM groups was 90.0 and 88.9% (p=0.904). CONCLUSION: Stent placement as a bridge to surgery can be performed safely and represents an alternative to emergency surgery with good short-term results. Stent placement as a bridge to surgery is also comparable to emergency surgery in long-term outcomes.

We present a 32-year-old, extremely obese, pregnant woman who developed severe hypotension and water intoxication after an accidental injection of large bolus of oxytocin during cesarean section under general anesthesia. The patient was initially thought to have an amniotic fluid embolism because of the abrupt hemodynamic changes developed immediately after fetal delivery and lack of recognition of medication error. It is highly recommended that careful attention should be paid not only to the possibility of hemodynamic deterioration and water intoxication if oxytocin is given rapidly in excessive doses, but to the confirmation of the proper use of the drug before it is injected.

Atelectasis is a fairly common complication in patients undergoing general anesthesia. However, atelectasis caused secretion plugs in patients with tracheopleural fistula is less common than other airway fistulas such as trachea and bronchus. Anesthesiologists should make every effort for thorough preoperative preparation to prevent atelectasis and using appropriate and aggressive treatment, including tracheal or bronchial clearing and end expiratory positive pressure. We report a case of an intraoperative occurrence of atelectasis of the lower lobe of a dependent lung in a patient with a tracheopleural fistula during single lung ventilation for primary closure.

Objective:
To evaluate the efficacy and safety of 8 weeks of resistance circuit training in people with paraplegia due to spinal cord injury.
Methods:
Participants were randomized into experimental and control groups. Although the intensity and sequence of movements of the exercise programs were identical in both groups, the resting time between sets was limited to 1 minute in the experimental group. In the control group, the participants were allowed to rest until they were comfortable. Both groups received 8 weeks of training twice per week. Before and after the program, muscle mass, body fat percentage, fat mass, blood pressure, heart rate, muscle strength and muscular endurance were evaluated, and 6-minute propulsion test was conducted. Additionally, the safety of the program was assessed.
Results:
Twenty-two individuals with paraplegia were enrolled (11 in each group). After the training program, the experimental group showed a significant decrease in the resting blood pressure and improvement in the upper extremity muscle mass, strength, and endurance (p<0.05). Each variable showed significant inter-group differences (p<0.05). Furthermore, none of the participants showed autonomic adverse events, musculoskeletal side effects, or discomfort.
Conclusion
The results show that resistance circuit training programs with short resting intervals are superior to the usual resistance exercise programs in improving the blood pressure and physical strength and are safe for people with upper thoracic level injuries at T6 or higher.

BACKGROUND: The extracellular matrix (ECM) produced by dermal fibroblasts supports skin structure, and degradation and/or reduced production of ECM are the main causes of wrinkle formation. OBJECTIVE: The aim of this study was to identify the active ingredient that enhances ECM production in dermal fibroblasts. METHODS: Polarity-based fractionation was used to isolate the active ingredient from natural extracts, and the effects of cedrol (isolated from Pterocarpus indicusirginia) on ECM production in cultured human dermal fibroblasts was investigated by reverse transcription-polymerase chain reaction, enzyme linked immunosorbent assay, and Western blot analysis. RESULTS: Cedrol accelerated fibroblast growth in a dose-dependent manner and increased the production of type 1 collagen and elastin. Phosphorylation of p42/44 extracellular signal-regulated kinase, p38 mitogen-activated protein kinase, and Akt was markedly increased by cedrol, indicating that enhanced ECM production is linked to activation of intracellular signaling cascades. CONCLUSION: These results indicate that cedrol stimulates ECM production, with possible applications to the maintenance of skin texture.
