Adenosine deaminase (ADA), an enzyme essential for the differentiation of lymphoid cells, has been used for monitoring diseases with altered immunity. The purpose of this study was to investigate the changes in serum ADA activity throughout normal pregnancy. We measured the catalytic values of serum ADA from 202 normal pregnant women using a commercial kit. Subjects were divided into four groups according to the gestational age in weeks (Gwks) (Group I: 5-9 Gwks [n=58]; Group II: 15-20 Gwks [n= 63]; Group III: 24-30 Gwks [n=34]; Group IV: 30-39 Gwks [n=47]). The serum ADA levels for the Groups I, II, III, and IV were as follows: 20.1+/-6.9 IU/L, 20.0+/-7.6 IU/L, 37.9+/-19.9 IU/L, and 24.5+/-8.6 IU/L, respectively. The serum ADA activity of group III was significantly higher than the other groups (p<0.05). However, there was no significant correlation between the Gwks and the serum ADA activity. Furthermore, other parameters, such as maternal age (p=0.29), gestational age at delivery (p=0.07), delivery mode (p=0.39), and birth weight (p=0.59) had no correlation with ADA activity. Reference values of serum ADA in normal pregnancy may provide important database for making clinical decisions in pregnancies complicated by conditions where cellular immunity has been altered.

OBJECTIVE: The object of this study was to evaluate the indications, effectiveness and complications associated with arterial embolization as a safe and effective alternative treatment of obstetrical hemorrhage. METHODS: From September 1998 to October 2005, 42 patients who had a pregnancy related hemorrhage which did not respond to treatment using obstetric maneuvers and uterotonic drugs were included in our study. The patients underwent angiographic embolization for the management of intractable obstetrical hemorrhage at Department of Obstetrics and Gynecology, Yonsei University Medical Center. All available medical records and telephone interviews were reviewed and detailed to collect adequate clinical data such as clinical status, underlying conditions, amount of transfusion, embolization sites, materials of embolization, hospital stay, the success rate and the complications. RESULTS: We have experienced clinically successful embolization in 40 (95.2%) of 42 patients of obstetrical hemorrhage resulting from various causes. After embolization, the patient's vital sign was stabilized. The causes of hemorrhage were atony of uterus (n=17), cervical pregnancy (n=5), abnormal placentation (n=5), laceration of uterine cervix and vagina (n=6). The average amount of blood transfusion was 10.3 unit (range; 0-63 unit). The average duration of hospitalization was 7.4 days (range; 4-18 days). We were able to follow up on 32 patients. The main complications after embolization were hypomenorrhea (n=6), numbness of lower extremities (n=3). In all cases menses resumed spontaneously after procedures. CONCLUSION: The arterial embolization is one of the safe and the effective procedures and offers patients a fertility-preserving alternative to hysterectomy for treatment of intractable postpartum hemorrhage.

There have been a few reports of pneumococcal meningitis complicated by spinal epidural abscess. A 58-year-old female with Streptococcus pneumoniae meningitis underwent a recurrent pleocytosis without apparent clinical deterioration after appropriate antibiotic treatment. Subsequently, she developed a spinal epidural abscess. Spinal epidural abscess is a rare complication of pneumococcal meningitis, and subclinical deterioration of neutrophil-dominant pleocytosis may precede development of a spinal epidural abscess in individuals with bacterial meningitis.

Background: Post-transplant diabetes mellitus (PTDM) is a risk factor for poor outcomes after kidney transplantation (KT). However, the outcomes of KT have improved recently. Therefore, we investigated whether PTDM is still a risk factor for mortality, major atherosclerotic cardiovascular events (MACEs), and graft failure in KT recipients. Methods: We studied a retrospective cohort of KT recipients (between 1994 and 2017) at a single tertiary center, and compared the rates of death, MACEs, overall graft failure, and death-censored graft failure after KT between patients with and without PTDM using Kaplan-Meier analysis and a Cox proportional hazard model. Results: Of 571 KT recipients, 153 (26.8%) were diagnosed with PTDM. The mean follow-up duration was 9.6 years. In the Kaplan- Meier analysis, the PTDM group did not have a significantly increased risk of death or four-point MACE compared with the non-diabetes mellitus group (log-rank test, P=0.957 and P=0.079, respectively). Multivariate Cox proportional hazard models showed that PTDM did not have a negative impact on death or four-point MACE (P=0.137 and P=0.181, respectively). In addition, PTDM was not significantly associated with overall or death-censored graft failure. However, patients with a long duration of PTDM had a higher incidence of four-point MACE. Conclusion Patient survival and MACEs were comparable between groups with and without PTDM. However, PTDM patients with long duration diabetes were at higher risk of cardiovascular disease.

Pulmonary artery sarcoma (PAS) is a rare and fatal disease that often mimics chronic thromboembolic pulmonary hypertension (CTEPH); therefore, diagnosis of PAS is often delayed. Herein, a healthy 74-year-old man was presented with a 4-month history of dyspnea. Chest computed tomography showed wall thickening and stenosis in the main pulmonary artery as well as in both proximal pulmonary arteries. In order to differentiate between unusual CTEPH, vasculitis, and PAS, we performed right heart catheterization and pulmonary angiography. The mean pulmonary arterial pressure was 21 mmHg, and there was severe pulmonary artery stenosis. Thrombi on the pulmonary arterial wall lesions were observed in intravascular ultrasound and optical coherence tomography. Furthermore, the patient had a history of deep vein thrombosis. Therefore, we diagnosed unusual CTEPH. After 6 months of rivaroxaban anticoagulation therapy, a chest X-ray revealed a left lower lobe lung mass, and a positron emission tomography later showed hypermetabolic lesions in the main pulmonary artery wall, in both pulmonary arteries walls, in the lung parenchyma, and in the bones. A biopsy of the right proximal humerus lesion revealed undifferentiated intimal sarcoma. Pulmonary sarcoma is rare, but should be considered when differentially diagnosing main pulmonary artery wall thickening and stenosis. A positron emission tomography may aid in this diagnosis.

OBJECTIVE: Alcoholic neuropathy is characterized by allodynia (a discomfort evoked by normally innocuous stimuli), hyperalgesia (an exaggerated pain in response to painful stimuli) and spontaneous burning pain. The aim of the present study is to investigate the effect of rolipram, a phosphodiesterase 4 inhibitor, against alcohol-induced neuropathy in rats. METHODS: Allodynia was induced by administering 35% v/v ethanol (10 g/kg; oral gavage) to Spraue-Dawley rats for 8 weeks. Rolipram and saline (vehicle) were administered intraperitoneally. Mechanical allodynia was measured by using von Frey filaments. Somatosensory evoked potential (SEP) was proposed as complementary measure to assess the integrity of nerve pathway. RESULTS: The ethanol-induced mechanical allodynia began to manifest from 3 week, and then peaked within 1 week. Beginning from 3 week, latency significantly started to increased in control group. In rolipram treated rats, the shorter latency was sustained until 8 weeks (p<0.05). The mechanical allodynia, which began to manifest on the 3 weeks, intraperitoneal injections of rolipram sustained statistical difference until 8 weeks, the final week of the study (p<0.05). CONCLUSION: This study suggests that rolipram might alleviate mechanical allodynia induced by alcohol in rats, which clearly has clinical implication.

Pleural effusion is a common pulmonary manifestation of systemic lupus erythematosus (SLE) and often occurs as bilateral exudative pleural effusion. The condition usually responds quickly to corticosteroid therapy. However, massive pleural effusion refractory to immunosuppressive drugs has rarely been reported; thus, the proper therapeutic modality is largely decided on a case-by-case basis. In this case, we describe successful treatment with surgical pleurectomy for massive refractory pleural effusion in a patient with SLE.

Gastric hepatoid adenocarcinoma is a rare adenocarcinoma that develops in the stomach. The prognosis of gastric hepatoid adenocarcinoma is poorer than that of ordinary gastric adenocarcinoma. Here, we report the first case of human epidermal growth factor receptor 2 (HER2)-positive gastric hepatoid adenocarcinoma in Korea. A 57-year-old male presented with abdominal distension and underwent endoscopic gastric biopsy and percutaneous core needle liver biopsy. The pathological findings were consistent with HER2-positive gastric hepatoid adenocarcinoma. He received six cycles of chemotherapy with cisplatin-capecitabine plus trastuzumab, which is a HER2 targeted agent. After chemotherapy, a follow-up abdominal computed tomography scan showed a partial tumor response. This case emphasizes the importance of using trastuzumab in a patient with HER2-positive gastric hepatoid adenocarcinoma.

Objective: Adults with autism spectrum disorders (ASD) experience significant difficulties with executive functioning (EF) and related adaptive skills, yet the lack of interventions in South Korea targeting these areas has resulted in a heightened need to develop an evidence- based program. Therefore, we developed a novel intervention aiming to enhance everyday EF and daily adaptive skills in adults with high-functioning ASD and conducted a pilot study to evaluate the validity and feasibility of the program. Methods: A behavioral intervention of 10-weekly sessions was developed based on literature searches and focus group interviews. Seven adults with high-functioning ASD (mean age=20.29) participated in a single-group pilot trial. We used self and parent-report questionnaires as well as skills measured by assessment instruments to analyze differences before and after the intervention. Results: Significant improvements were shown in everyday EF, including time management, organization, self-restraint, and regulation of emotions. Additionally, results demonstrated an enhancement in adaptive functioning, especially in the subdomains of daily living skills. Analyses of parental outcomes only revealed a significant decrease in the scores of emotion regulation. Conclusion The current study provides good evidence for the validity and feasibility of an intervention to improve everyday EF and adaptive skills in adults with ASD.
