Risk Factors for Dieulafoy Lesions in the Upper Gastrointestinal Tract

BACKGROUND/AIMS: The purpose of this study is to verify the risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract. METHODS: A case-control study was performed by reviewing the electronic medical records of 42 patients who were admitted to a tertiary medical center in the Daejeon region for Dieulafoy lesions from September 2008 to October 2013, and the records of 132 patients who were admitted during the same period and who underwent endoscopic examination for reasons other than bleeding. We analyzed clinical and endoscopic findings retrospectively, and searched for risk factors associated with Dieulafoy lesion formation. RESULTS: All 42 patients diagnosed with Dieulafoy lesion had accompanying bleeding, and the location of the bleeding was proximal in 25 patients (59.5%), the middle portion in seven patients (16.7%), and distal in 10 patients (23.8%). Antiplatelet agents (p=0.022) and alcohol (p=0.001) use showed statistically significant differences between the two groups. The odds ratios (95% confidence intervals) of the two factors were 2.802 (1.263 to 6.217) and 3.938 (1.629 to 9.521), respectively. CONCLUSIONS: This study showed that antiplatelet agents and alcohol consumption were risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract.

Vertebral Osteomyelitis caused by Burkholderia cepacia in an Immunocompetent Elderly Patient After Acupuncture

Burkholderia cepacia is an important nosocomial pathogen in hospitalized patients, particularly those with prior antimicrobial therapy. B. cepacia causes various clinically significant infections such as bacteremia, pneumonia, and urinary tract and surgical site infections. However, osteomyelitis caused by B. cepacia is very rare. We present a case of B. cepacia vertebral osteomyelitis with review of the literature.

Endovascular Treatment of a Ruptured Posterior Inferior Cerebellar Artery Aneurysm during Pregnancy

Aneurysmal subarachnoid hemorrhage (SAH) during pregnancy is quite rare, however it has a high maternal mortality rate. A pregnant woman in the 16th gestational week was admitted to our hospital with a drowsy level of consciousness. A brain magnetic resonance (MR) image showed hemorrhage on the prepontine cistern, and both sylvian fissures, and MR angiography and cerebral digital subtraction angiography demonstrated an aneurysm at the left posterior inferior cerebellar artery (PICA). We performed endovascular coil embolization attempting to minimize radiation exposure. She was discharged with no neurologic deficit and delivered a healthy baby by cesarean section at the 38th week of gestation. This case study reported the shortest gestational period and this is the first report on an aneurysmal rupture arising from PICA which was treated using an endovascular method. Using an appropriate technique for reduced radiation exposure to the fetus and limited alterations in maternal-fetal physiology, endovascular coil embolization could guarantee good results in treatment of aneurysmal SAH in pregnant women.

Mortality and Real Cause of Death from the Nonlesional Intracerebral Hemorrhage

OBJECTIVE: The case fatality rate of nonlesional intracerebral hemorrhage (n-ICH) was high and not changed. Knowing the causes is important to their prevention; however, the reasons have not been studied. The aims of this study were to determine the cause of death, to improve the clinical outcomes. METHODS: We retrospectively analyzed consecutive cases of nonlesional intracerebral hemorrhage in a prospective stroke registry from January 2010 to December 2010. RESULTS: Among 174 patients (61.83+/-13.36, 28-90 years), 29 patients (16.7%) died during hospitalization. Most common cause of death was initial neurological damage (41.4%, 12/29). Seventeen patients who survived the initial damage may then develop various potentially fatal complications. Except for death due to the initial neurological sequelae, death associated with immobilization (such as pneumonia or thromboembolic complication) was the most common in eight cases (8/17, 47.1%). However, death due to early rebleeding was not common and occurred in only 2 cases (2/17, 11.8%). Age, initial Glasgow Coma Scale, and diabetes mellitus were statistically significant factors influencing mortality (p<0.05). CONCLUSION: Mortality of n-ICH is still high. Initial neurological damage is the most important factor; however, non-neurological medical complications are a large part of case fatality. Most cases of death of patients who survived from the first bleeding were due to complications of immobilization. These findings have implications for clinical practice and planning of clinical trials. In addition, future conduct of a randomized study will be necessary in order to evaluate the benefits of early mobilization for prevention of immobilization related complications.

Nondiabetic kidney diseases in type 2 diabetic patients

BACKGROUND: The aim of this study was to evaluate the clinical characteristics of nondiabetic nephropathy in type 2 diabetes mellitus patients and to find a clinical significance of renal biopsy and immunosuppressive treatment in such a patient. METHODS: Renal biopsy results, clinical parameters, and renal outcomes were analyzed in 75 diabetic patients who underwent kidney biopsy at Chungnam National University Hospital from January 1994 to December 2010. RESULTS: The three most common reasons for renal biopsy were nephrotic range proteinuria (44%), proteinuria without diabetic retinopathy (20%), and unexplained decline inrena lfunction (20.0%). Ten patients (13.3%) had only diabetic nephropathy (Group I); 11 patients (14.7%) had diabetic nephropathy with superimposed nondiabetic nephropathy (Group II); and 54 patients (72%) had only nondiabetic nephropathy (Group III). Membranous nephropathy (23.1%), IgA nephropathy (21.5%), and acute tubulointerstitial nephritis (15.4%) were the three most common nondiabetic nephropathies. Group III had shorter duration of diabetes and lesser diabetic retinopathy than Groups I and II (P = 0.008).Group II had the lowest baseline estimated glomerular filtration rate (P = 0.002), with the greatest proportion of renal deterioration during follow-up (median 38.0 months, P < 0.0001). The patients who were treated with intensive method showed better renal outcomes (odds ratio 4.931; P = 0.01). Absence of diabetic retinopathy was associated with favorable renal outcome in intensive treatment group (odds ratio 0.114; P = 0.032). CONCLUSION: Renal biopsy should be recommended for type 2 diabetic patients with a typical nephropathy because a considerable number of these patients may have nondiabetic nephropathies. And intensive treatment including corticosteroid or immunosuppressants could be recommended for type 2 diabetic patients with nondiabetic nephropathy, especially if the patients do not have diabetic retinopathy.

Retrospective Study for the Isolation of Influenza Virus and Prevalence Period in Busan from 2000 to 2002 / 소아과

PURPOSE: During epidemics, influenza induces a high mortality and morbidity, and when influenza is prevalent, it is revealed by increased pneumonia, hospitalization due to influenza-like illness, and mortality in community. We aimed at the isolation of influenza virus and prevalence period in Busan from 2000 to 2002. METHODS: For 3 years from 2000 to 2002, we analyzed the patterns of influenza virus, the occurrence distribution of influenza by age and sex and the prevalence period after cultivating the examined materials from throat smears and snivel, collected from patients in St. Benedict Hospital Pediatrics Department, from 10 monitoring hospitals, and from 16 public health centers. RESULTS: For three years, a total of 209 strains of influenza virus were isolated. In 2000, there were A/sydney/05/97(H3N2)-like, A/Beijing/262/95(H1N1)-like and B/Harbin/07/94-like. In 2001, there were A/Panama/2007/99(H3N2)-like and A/Newcaledonia/20/99(H1N1)-like. In 2002, there were A/Panama/ 2007/99(H3N2)-like, A/Newcaledonia/20/99(H1N1)-like, B/Beijing/243/97, B/Honkong/22/2001 and B/ Sichuam/379/99. The occurrence distribution by sexes were 14 males and 25 females in 2000, 23 males and 33 females in 2001, 57 males and 57 females in 2002. As for the occurrence distribution by ages, 0-10 years made up 48.4 percent in 2000, 11-20 years 33.93 percent in 2001, and below 10 years was 64.91 percent in 2002. As for the occurrence distribution by month, the rate was once high in January and somewhat high in April and by June, when there happened to be various viruses, though there was a low rate in 2000. On the other hand, the virus was concentrated in February and March in 2001. And in 2002, it happened high twice, in March and November. CONCLUSION: Influenza virus revealed frequent antigenic changes and infect children, especially those below 10 years of age from late fall to early spring. So we should consider appropriate prevention in children.

Cord blood Cytokines on the Development of Cerebral Palsy in Premature Infant / 소아과

PURPOSE: This study was performed to determine the relation between cord blood plasma cytokines responses and development of cerebral palsies in premature infants. METHODS: Interleukin-1beta(IL-1beta), Interleukin-6(IL-6), Tumor necrosis factor-alpha(TNF-alpha) were measured using ELISA kits in premature infants(n=60) who were admitted to St. Benedict Hospital from September 2001 to June 2003. Retrospective study was done by review of medical records. RESULTS: Cord blood levels of IL-1beta, IL-6 and TNF-alpha in the cerebral palsy group were higher, especially IL-6 but were not significant, compared with the control group. Cord blood levels of IL-6 in the cerebral palsy without asphyxia, sepsis, PROM, RDS and pneumonia were significantly different, compared with the control group. CONCLUSION: Cord blood levels of IL-1beta, IL-6 and TNF-alpha in the cerebral palsy group were increased, but concentrations of IL-6 increased significantly. Cord blood levels of IL-6 may be a useful value to predict the development of cerebral palsy, because they are related to IL-6 rather than to TNF-alpha & IL-1beta in this study.
