ABSTRACT

Purpose@#We analyzed the learning curve of single-port robotic (SPR)-assisted rectal cancer surgery. @*Methods@#Fifty-seven consecutive SPR-assisted rectal cancer surgery cases performed by the same surgeon were considered in surgical interventions for rectal cancer. Total operation time (OT), docking time (DT), and surgeon console time (SCT) measured during surgery were used to parametrize the learning curve. The parameters representing the learning curve were evaluated using the cumulative sum (CUSUM). @*Results@#The mean value of total OT was 241.8 ± 91.7 minutes, the mean value of DT was 20.6 ± 19.1 minutes, and the mean value of SCT was 135.9 ± 66.7 minutes. The learning curve was divided into phase 1 (initial 16 cases), phase 2 (second 16 cases), and phase 3 (subsequent 25 cases). The peak on the CUSUM graph occurred in the 21st case. The longest OT among phases was in phase 2. Complications were most frequent in phase 2. However, complications of Clavien-Dindo (CD) grade IIIb were most frequent in phase 3 with 2 patients. The most common complications were fluid collection and urinary retention (7 patients each). Complications of CD grade IIIb required one stomal revision due to stoma obstruction and one irrigation and loop ileostomy due to anastomosis leakage. @*Conclusion@#Improvement in surgical performance of SPR assisted rectal cancer operation was achieved after 21 cases.The three phases identified in the cumulative sum analysis showed a significant decrease in operative time after the middle stage of the learning curve without an increase in the complication rate.

ABSTRACT

Purpose@#The impact of postoperative complications on long-term oncologic outcome after radical colorectal cancer surgery is controversial. The aim of this study was to examine the risk factors and oncologic outcomes of surgery-related postoperative complication groups. @*Methods@#From January 2010 to December 2010, 310 patients experienced surgery-related postoperative complications after radical colorectal cancer surgery. These stage I–III patients were classified into 2 subgroups, minor (grades I, II) and major (grades III, IV) complication groups, according to extended Clavien-Dindo classification system criteria. Clinicopathologic differences between the 2 groups were analyzed to identify risk factors for major complications. The diseasefree survival rates of surgery-related postoperative complication groups were also compared. @*Results@#Minor and major complication groups were stratified with 194 patients (62.6%) and 116 patients (37.4%), respectively. The risk factors influencing the major complication group were pathologic N category and operative method. The prognostic factors associated with disease-free survival were preoperative perforation, perineural invasion, tumor budding, and receiving neoadjuvant therapy. With a median follow-up period of 72.2 months, the 5-year disease-free survival rates were 84.4% in the minor group and 78.5% in the major group, but there was no statistical significance between the minor and major groups (P = 0.392). @*Conclusion@#Advanced cancer and open surgery were identified as risk factors for increased surgery-related major complications after radical colorectal cancer surgery. However, severity of postoperative complications did not affect disease-free survival from colorectal cancer.

ABSTRACT

PURPOSE: With feasibility in the diagnoses of congenital heart disease (CHD) in the antenatal period, we suspect changes have occurred in its incidence. No data have been reported about the current incidence of simple forms of CHD in Korea. We have attempted to assess the recent incidence and characteristics of CHD in the neonatal care unit of a secondary referral medical center. METHODS: Medical records of 497 neonatal care unit patients who underwent echocardiography in the past 5 years were reviewed. Pre-term infants with patent ductus arteriosus and other transient, minimal lesions were excluded from this study. RESULTS: Although the number of inpatients remained stable, the incidence of simple forms of CHD showed a gradual decrease over the 5-year study period; a markedly low incidence of complex forms was seen as well. CHD was observed in 3.7% full-term and 6.8% pre-term infants. CHD was observed in 152 infants weighing >2,500 g (3.5% of corresponding birth weight infants); 65 weighing 1,000 to 2,500 g (9.3%); and 6 weighing <1,000 g (8.0%). The incidence of CHD was higher in the pre-term group and the low birth weight group than in each corresponding subgroup (P<0.001); however, the incidence of complex CHD in full-term neonates was high. The number of patients with extracardiac structural anomalies has also shown a gradual decrease every year for the past 5 years. CONCLUSION: Findings from our study suggest that the recent incidence and disease pattern of CHD might have changed for both complex and simple forms of CHD in Korea.

ABSTRACT

PURPOSE: We evaluated Kawasaki disease(KD) in children in order to evaluate the clinical characteristics and coronary complication of infantile Kawasaki disease. METHODS: A total of 226 medical records of children with KD admitted to The Catholic University of Korea, St. Mary's Hospital, from 1994 to 2003 were retrospectively analyzed. RESULTS: The incidence of lymphadenopathy was statistically lower in infantile Kawasaki disease than in Kawasaki disease of children older than one year. The incidence of atypical Kawasaki disease in infant(32%) was greater than that of total patients(24%), but there was no statistically significant difference in two groups. The incidence of coronary complication in atypical Kawasaki disease in children younger than one year was 50%(6/12), which was greater than that of coronary complication in typical KD of children older than one year. CONCLUSION: Diagnostic difficulties in infantile Kawasaki disease are due to high incidence of atypical characteristics of Kawasaki disease. Yet, early treatment with IVGV and aspirin is necessary because of its high incidence of coronary complication.

ABSTRACT

PURPOSE: Valproic acid (VPA) has been used as an anticonvulsant for a long time. Recently, there are many reports on VPA activity with regards to intracellular signal transduction, including differentiation, proliferation, and apoptosis. We experienced several hematologic toxicities during the long-term use of VPA. Therefore, we investigated whether VPA has effects on short-term or long-term hematopoiesis with respect to differing concentrations. METHODS: We obtained bone marrow mononuclear cells (BMMNC) from a 5 week old female C3H/He strain mouse. The BMMNC were cultured in semi-solid media mixed with VPA according to the concentrations of colony forming unit for granulocyte-monocytes (CFU-GM). The concentrations of VPA were used as follows: 0.01 mM, 0.1 mM, 1 mM, and 10 mM (therapeutic level: 0.07~1.1 mM). We performed long-term liquid culture under VPA to compare the frequency of long-term culture initiating cells (LTC-IC) according to various VPA levels. RESULTS: The number of CFU-GM was highest with 1 mM of VPA (45.2+/-13.5), with higher therapeutic level than control (25.7+/-11.9), in 0.01 mM of VPA (26.5+/-12.1) and in 0.1 mM of VPA (26.6+/-12.2). In 10 mM of VPA, a toxic level of VPA, was the lowest at 1.6+/-1.1 (P< 0.01). In long-term culture, the frequency of LTC-IC was increased in 0.1 mM of VPA (67.7+/-16.3%), lower therapeutic level than in control (5.5+/-10.6%). In 1 mM of VPA, the high therapeutic level decreased to 81.6+/-9.3%. With toxic levels of VPA, 10 mM, there was no hematopoiesis. CONCLUSION: The VPA might enhance short-term hematopoiesis at high therapeutic levels, while preserving LTC-IC in long-term hematopoiesis under low therapeutic concentrations. Therefore, we suggest that VPA to be used within a low therapeutic level to escape from hematopoietic suppression when using VPA as long-term medication for seizure control.

ABSTRACT

PURPOSE: Intravenous immune globulin(IVIG) as a treatment for the Kawasaki disease (KD) has reduced the coronary complications. But, some patients suffer from coronary complication despite early IVIG infusion, and it is difficult to discriminate the susceptible patients in the acute phase. It is also challenging to decide additional therapy in cases showing fever after IVIG therapy. We investigated the relationship between intervals from the onset of fever to the day of peak laboratory values and coronary complications. METHODS: We reviewed the charts of KD patients with coronary aneurysm(group A, n=13) and without aneurysm(group B, n=35). All patients got IVIG therapy early in the acute phase and additional therapy in cases fever recurred. We counted the days from onset of fever to the peak level of acute phase reactants and analyzed the differences between two groups with t-test. RESULTS: In the comparison of two groups, the mean intervals from the onset of fever to peak CRP level was 9.23+/-4.71 days in group A, 6.63+/-2.47 days in group B. The mean intervals to peak ESR was 13.31+/-7.06 days in group A, 8.37+/-3.01 days in group B. The mean intervals to highest platelets counts was 14.62+/-4.96 days in group A, 11.14+/-3.59 days in group B. All of these results showed statistically significant differences. CONCLUSION: Our results show that the KD patients with coronary aneurysm have longer intervals between the onset of fever to day of peak acute reactants in spite of the aggressive treatment than those without aneurysm. So, in cases of KD with relapsing fever in spite of IVIG and the acute reactants are in the course of increment, additional immune modulation therapy and short term follow ups with echocardiography would be needed.

ABSTRACT

The role of nitric oxide during neonatal sepsis is complex. We tested the hypothesis that nonselective inhibition of nitric oxide synthase with N(w) -nitro-L-arginine methyl ester (L-NAME) is detrimental during the early phase of experimental sepsis in the newborn piglet. Newborn piglets were divided into four groups: 6 in the control group, 6 in the L-NAME control group, 12 in the sepsis group (SG), and 11 in the sepsis with L-NAME group (NS). Sepsis was induced by intravenous injection of 10(8) colony forming units of Escherichia coli. L-NAME 10 mg/kg was given intravenously 60 min before the induction of sepsis. The survival rate of piglets after 4 hr was 27% in NS, while it was 100% in other groups. Systemic hypotension, observed in both SG and NS, were more profound in NS. Leukopenia was observed in both SG and NS. Thrombocytopenia, prolongation of prothrombin time and activated partial thromboplastin time, and increase in thrombin-antithrombin complexes were observed only in NS. Decreased PaO2 /FiO2 ratio, arterial pH and base excess, and increased blood lactate levels observed in both SG and NS, but were more profound in NS. These findings suggest that nonselective inhibition of nitric oxide synthase with L-NAME is detrimental during the early phase of experimental neonatal sepsis.

ABSTRACT

PURPOSE: We investigated incidence of feeding intolerance and time when normal enteral feeding can be established in full term neonates with hypoxic-ischemic encephalopathy (HIE). METHODS: We reviewed medical records of 61 full term infants with HIE who were admitted to St. Paul's Hospital from Jan. 1996 to Dec. 2001. The incidence of feeding intolerance, day of first feeding, and day of full enteral feeding were studied in respective to Sarnat stages. RESULTS: Among the full term with HIE, 32 were classified into stage I, 20 into stage II, and 9 into stage III. The incidence of feeding intolerance was 6%, 30%, and 89% for stages I, II and III, respectively. There was only one case of necrotizing enterocolitis among infants of stage III HIE. Feeding first began on 0.13+/-0.01 postnatal day (PND) in normal infants compared to 0.15+/-0.03 PND in infants of stage I, 3.24+/-1.82 PND in stage II and 5.58+/-2.50 PND in stage III. The incidence of feeding intolerance, day of first feeding, and day of normal enteral feeding achieved in infants with stage I were not different from those of normal infants but significantly higher and delayed in infants with more severe degrees of encephalopathy. CONCLUSION: The first feeding should vary according to severity of encephalopathy so as to lower the incidence of feeding intolerance and the risk of necrotizing enterocolitis. We suggest that infants of stageIencephalopathy be first fed as same as normal infants, but precaution is in order when deciding an appropriate time to start feeding in infants of stage II, III encephalopathy.

ABSTRACT

PURPOSE: Recently, Staphylococcus aureus has been reported as the principal microorganism isolated from impetigo, showing variable degrees of antimicrobial resistance. The aim of this work was to study the causative organism of impetigo the their antimicrobial susceptibility developed in impetigo in the past four years. METHODS: We performed bacterial cultures and antimicrobial susceptibility tests in 73 patients with impetigo who visited the Department of Dermatology and Pediatrics at St. Paul's Hospital of the Catholic University of Korea in Seoul. RESULTS: Of 73 patients, microorganisms were identified in 70 patients between May 1995 and August 1999. Staphylococcus aureus was isolated from 63 (90%) patients. Antimicrobial susceptibility test for Staphylococcus aureus revealed low resistance to bactrim (0.0%), rifampicin (0.0%), van- comycin (3.2%), ceftriaxone (4.0%), imipenem (5.4%), ampicillin-clavulanic acid (6.1%), oxacillin (8.1%), cephazolin(9.1%), cephalothin (9.7%) and cefotaxime (10.8%). However, Staphylococcus aureus had high resistance to erythromycin (65.7%) and gentamicin(85.5%). Thirty-six (57.1%) strains of isolated Staphylococcus aureus showed resistance to more than one drug, including two strains (3.1%) resistant to more than 10 drugs. CONCLUSION: Staphylococcus aureus was the most common cause of impetigo developed in the pa- st four years. It was susceptible to most antimicrobial agents except erythromycin and gentamicin, and methicillin resistance was not strong in our results.

ABSTRACT

Median cleft face syndrome is diagnosed by two or more of the following anomalies : ocular hypertelorism, cranium bifidum occultum, median cleft nose, median cleft lip and median cleft premaxilla. The most consistent and prominent ocular finding associated with this syndrome is hypertelorism. We experienced a case of median cleft face syndrome which had orbital hypertelorism, cranium bifidum occultum, bifid cleft nose, V-shaped frontal hairline, and polysyndactly. We report this case with a brief review of the associated literature.

ABSTRACT

Wolf-Hirschhorn syndrome is caused by a partial loss of the distal short arm of chromosome 4. Characteristic clinical features are severe growth retardation, mental retardation, seizures, congenital cardiac defects, urogenital abnormalities, microcephaly, hypertelorism, prominent glabella, cleft lip and palate and micrognathia. In 87% of cases, chromosome 4 deletion arises as a de novo event, whereas in the remaining cases it is derived from a familial balanced translocation. Chromosomal study of the patient showed 46 XX der(4)t(4;18)(p15.2;q23), and the patient's mother was found to have a balanced translocation, 46 XX t(4;18)(p15.2;q23).

ABSTRACT

PURPOSE: Umbilical cord blood transplantation is a alternative method as new hematopoietic stem cell transplantation and has been performed clinically in indicated disease. However, it have the problems for long-term storage of cord blood in liquid nitrogen and for limited application to adult due to small amount of hematopoietic stem cell. Therefore, several centers have carried out active research for ex vivo expansion of cord blood stem cell. We investigated the hematopoietic function of cord blood plasma for development of new techniques. METHODS: We acquired the nucleated cells of cord blood from healthy infant and bone marrow from healthy donor received granulocyte-colony stimulating factor. We evaluated hematopoietic colony formation according to source of stem cell and plasma by semisolid culture medium. Three experimental groups were divided as source of plasma: group for cord plasma, group for bone marrow plasma, group for mixture of cord plasma and bone marrow plasma. RESULTS: The results were as follows: 1) The colony formation according to source of stem cell in commercialized standard semisolid culture medium showed that cord blood in the number of CFU-GM was less than bone marrow, but not significantly different in CFU-GEMM. 2) The colony formation according to source of stem cell in semisolid culture medium using experimental plasma showed that cord blood in the number of CFU-GM was more than bone marrow. There were no cytotoxic effect of plasma to experimental cells. 3) The colony formation in semisolid culture medium contained plasma according to experimental group showed that the number of CFU-GM in cord blood plasma was significantly more than bone marrow plasma in spite of different source of stem cell. Conclusions: These results suggested that cord blood might contain enough hematopoiesis to enable to perform transplantation compared with bone marrow and, also, cord blood plasma might be contributed more effective colony formation than bone marrow plasma. Therefore, we propose that it may be good to store cord blood cells with cord blood plasma in long-term storage. We will investigate the composition of hematopoietic growth factors and cytokines in cord blood plasma and the effect of cord blood plasma for ex vivo expansion of cord blood cells.

ABSTRACT

PURPOSE: Umbilical cord blood (CB) transplantation is an alternative method instead of allogeneic bone marrow (BM) transplantation. CB transplantation has used grafts with red blood cell (RBC) depletion but previous reports in CB investigated the immune reaction about mononulcear cell separated by density gradient. To study the real immune response in CB transplantation, the experimental group designed the total nuclear cell (TNC) groups by RBC depletion and the mononuclear cell (MNC) groups by Ficoll Hypaque in CB and BM. METHODS: We evaluated the various cytokine gene expression by semiquantitative RT- PCR method after immune stimulation with phytohemagglutinin in cord blood and bone marrow according to cell separation method. RESULTS: 1) All samples of CB and BM expressed IL-2 mRNA. There was no difference in amounts of IL-2 mRNA between CBTNC and CBMNC, between BMTNC and BMMNC. 2) All samples of CB and BM expressed IL-10 mRNA. There was no difference in amounts of IL-10 mRNA between the CBTNC and CBMNC but significantly different between the BMTNC and BMMNC (P<0.05). The amounts of IL-10 mRNA in the BMMNC and CBTNC group showed larger than in the BMTNC group (P<0.05). 3) The expression of IL-4, IFN-gamma was not shown in this study. These results suggest that no difference of IL-2 mRNA between CB and BM may reveal IL-2 as major cytokine gene in CB after immune stimulation. The expression of IL-10 mRNA in CBTNC showed more than in BMTNC group. Conclusion: Our results suggest that CBTNC may contain a lot of cells producing IL-10, as a cytokine of immunoregulatory function, and therefore the immune reaction in CB transplantation may be less apparent than in BM transplantation. The cell component producing IL-10 in CB may be T regulator cell. There were not showed the IFN-gamma and IL-4 mRNA due to short duration of immune stimulation. Therefore, further studies will identify the IL-4 and IFN-gamma mRNA expression after long time stimulation and various cytokine gene expression to certificate the precise immune response after flow cytometry to composed of immune cells in CB and BM.

ABSTRACT

Pseudohypoparathyroidism(PHP) is a genetic disorder characterized by target cell resistance to the effect of parathyroid hormone(PTH). The disorder is classified into type I a, I b, I c and II depending on the phenotype and biochemical findings. In type I a, urinary cyclic AMP and urinary phosphate excretion are not increased after PTH stimulation because of deficient G unit activity in target cells. Deficiency of the G unit is a generalized cellular defect and accounts for the association of other endocrine disorders with type I a PHP. Type I b PHP shows resistance to PTH but not to other hormones and normal phenotypic appearance. In type I c PHP affected children have defect in catalytic unit of adenylate cyclase and in addition to resistance to PTH, resistance to the metabolic effects of TSH, gonadotropins, and glucagon may be detected. Typical appearance of Albright's hereditary osteodystrophy is common in PHP type Ia and Ic. In type II PHP, urinary cyclic AMP response is generated but this does not lead to phosphaturia. We experienced two patients with PHP. One is a 11-year-old girl diagnosed type I a PHP and the other is a 11-year-old boy suspected type I b PHP. They visited emergency room because of tetanic movement. Both patients had no previous history of tetany and showed low serum calcium level, high phosphorus level and high PTH level. The girl had typical features of Albright's hereditary osteodystrophy such as round face, short neck, obese feature, brachydactyly and mental retardation but didn't have basal ganglia calcification on brain CT. The boy showed normal appearance and no mental retardation.

ABSTRACT

PURPOSE: The aim of this study was to elucidate the pathogenesis of vertical transmission of hepatitis B virus (HBV), and to study the protective efficacy of the vaccine and hepatitis B immune globulin (HBIG). METHODS: Eighty-two infants born from HBV carrier mothers were studied. HBV plasma-derived vaccine and HBIG were administered to their neonates. Then, changes of viral markers, anti-preS2 and HBV-DNA were observed for 12 months. RESULTS: The seroconversion rates of anti-HBs in infants of HBV carrier mothers at 4, 8 and 12 months were 85.4% (70/82), 75.6% (62/82) and 73.2% (60/82), respectively (P<0.05). The protective efficacy of the vaccine and HBIG at 12 months in infants from HBeAg positive and negative mothers were 89.5% and 100%, respectively. The detection rates of HBV-DNA by PCR in HBeAg positive and negative mothers were 83.3% (15/18) and 23.5% (8/34), respectively. By nested PCR, the detection rates improved to 94.4% (17/18) and 64.7% (22/34), respectively. In neonates from the HBeAg positive and negative mothers, HBV-DNA was only detected by nested PCR with 33.3% (6/18) and 2.9% (1/34), respectively. Five (6.1%) of 82 infants became infected by HBV from only HBeAg positive mothers during the follow-up period of 12 months. Three of 5 infected infants became HBV carriers. Detectable HBV-DNA (P=0.002) and HBsAg (P=0.02) in serum of infants at birth were significant factors to becoming a carrier. CONCLUSION: This study suggests that, in clarifying the HBsAg and HBV-DNA status in serum of the infants at birth, the highest risk group might be identified and treated with new and effective preventive methods.

ABSTRACT

Infantile acute hemorrhagic edema(IAHE) is a variant of leukocytoclastic vasculitis which is characterized by painful edematous purpura of cockade pattern on the head and distal extremities. The lesions are limited to the skin and complete recovery occurs within 1 to 3 weeks. Recently, it is accepted as a separate entity from Henoch-Sch nlein purpura. A nine month-old boy presented multiple cockade ecchymotic plaques and inflammatory edema on the face and extremities. He had recent upper respiratory infection and was in good general condition except mild fever. His skin lesions markedly improved within 7 days of treatment. We report a typical case of IAHE with analysis of the domestic case reports and review of the literatures.
