PURPOSE: This study investigated the influence of patent ductus arteriosus (PDA) and its treatment on incidence and progression of retinopathy of prematurity (ROP). METHODS: The authors retrospectively reviewed the medical records of 408 infants who underwent screening examinations for ROP at the Neonatal Intensive Care Unit of our hospital. RESULTS: The total incidence of ROP was 23.5% (96 out of 408) and the patients that needed treatment were 7.4% (30 out of 408). The mean birth weight and gestational age was 1406.1 grams and 30.67 weeks in patients without ROP, and 979.8 grams and 27.46 weeks in patients with ROP, respectively. In both total and very low birth weight (VLBW) patients, the incidence of ROP was higher in the PDA group than the non-PDA group, but the PDA group was an independent risk factor only in the VLBW group (p = 0.033). The incidence of threshold disease was not significantly different between the PDA and control groups (p = 0.757). There was no significant difference of incidence of ROP and threshold disease among the 3 treatment groups for PDA. CONCLUSIONS: In VLBW patients, the presence of PDA increased the risk of ROP and its progression, thus more attention is needed for PDA patients. However, there was no significant difference in ROP incidence and progression according to different PDA treatment methods.

OBJECTIVE: To evaluate the effects of piroxicam patch(Trast) in rheumatoid arthritis patients with knee joint pain and swelling and to determine the concentration of plasma and synovial fluid following patch application. METHODS: Twenty-two patients with rheumatoid arthritis participated in a double-blind, placebo-controlled study. The patients were instructed to apply piroxicam or placebo patch at one knee and re-apply it every other day for 2 weeks. They had washout period for 2 weeks and then applied the other patch for 2 weeks at the same joint. The patients recorded knee joint pain using visual analog scale. Knee joint swelling and tenderness were assessed before and after application of piroxicam and placebo patch. Complete blood count, AST, ALT, BUN, creatinine, joint fluid analysis were also done. Piroxicam concentration in plasma and synovial fluid were measured by high performance liquid chromatography(HPLC) after 2 weeks of piroxicam patch application. RESULTS: Knee joint pain improved significantly after the application of piroxicam patch for 2 weeks(visual analog scale, 56. 2+5. 9m vs 48. 2+5. 7mm, p=0. 03 by Wilcoxon signed rank test). There was no significant change in white cell count of synovial fluid, peripheral blood cell count, chemistry, C-reactive protein and erythrocyte sedimentation rate. In terms of adverse effects, mild gastrointesti nal disturbance(8/21 cases, 38%) and local side effects such as pruritus and ery thema(3/21 cases, 14%) were developed, which were insignificant compared with control groups(30%, 15% respectively). Piroxicam concentrations in plasma and synovial fluid after the application of piroxicam patch were 0. 129+0. 04ug/ ml (mean+SE) and 0. 644+0. 202ug/ml respectively. CONCLUSIONS: Piroxicam patch is a safe and effective therapeutic modality for knee joint pain in patients with rheumatoid arthritis. Mild adverse effects such as gastrointestinal disturbance and local side effects were noted. Piroxicam concentration was higher in synovial fluid than in plasma following the application of piroxicam patch.

To identify the central innervating the mammary nerve, viral retrograde transneuronal labelling methods were employed. Pseudorabies virus 6 microliter was injected into the mammary nerve of adult female Sprague-Dawley rats. After 4 days of survival, the animals were perfused with 4% paraformaldehyde-lysine periodate and their brains were processed for immunohistochemistry and double immunofluorescent staining of Pseudorabies virus or oxytocin using polyclonal antibodies. Several nuclei in brain were retrogradely labelled with Pesudorabies virus.Only a few magnocellular neurons of the paraventricular nucleus throughout whole brain showed double immunoreactivity to Pseudorabies virus and oxytocin. Approximately 11 percent of the oxytocinergic cells of the paraventricular nucleus,especially in three subnuclei[dorsomedial cap, lateral magnocelluar part and ventral part] showed double positive reaction to both Pseudorabies virus and oxytocin. These data demonstrate that some CNS cells projecting to the mammary nerve contained oxytocin and it may acts as a neurotransmitter in this pathway and a hormone targeting milk production and secretion.

Schizophrenia is a severe mental disorder that significantly impairs the daily functioning of patients that causes substantial societal and economic burden. While drug therapy is crucial for schizophrenia treatment, relying solely on antipsychotic drugs does not yield the most favorable therapeutic outcomes.Current Concepts: Integrating psychosocial interventions could result in maximized therapeutic effects for individuals living with schizophrenia. Evidence-based psychosocial interventions for schizophrenia management include cognitive behavioral therapy, family involvement, psychoeducation, supported employment programs, lifestyle adjustments for physical health, and coordinated and comprehensive early intervention services. Incorporating peer support, allowing both service users and care providers to share knowledge and their illnessrelated personal experiences, facilitates mutual assistance along the path to recovery. Moreover, growing interest follows in using digital interventions, such as wearable technology and smartphone applications, as effective therapeutic tools for illness management.Discussion and Conclusion: The above-mentioned psychosocial interventions empower individuals with schizophrenia, helping them improve their functioning, enhance their life quality, and adapt more effectively to society. Combining early medication with comprehensive psychosocial interventions, including digital technology, is crucial for the best outcomes. This approach should begin as soon as schizophrenia is diagnosed, aiming to promote recovery and overall well-being in affected individuals.

BACKGROUND: Arginine vasopressin has been used by prophylactic treatment of vasodilatory shock during coronary artery bypass graft (CABG). Vasopressin may be a cause of spasm in graft artery during CABG. We evaluated the effect of propofol on vasopressin-induced contraction in human gastroepiploic artery (GEA). METHODS: Human GEA were obtained from 35 patients (43-74 yr), undergoing subtotal gastrectomy. Vasopressin-induced a concentration contractions (10(-9) to 10(-6) M) were measured after exposed to without propofol, propofol 10(-5), 10(-4), 10(-3) M. After endothelium denuding vasopressin-induced a concentration contractions were measured with or without propofol 10(-3) M in calcium free solution. In the denuded vascular rings, with or without pretreatment of glibenclamide (10(-5) M), nicorandil (10(-5) M), or diltiazem (10(-5) M) were exposed to with or without propofol 10(-3) M, and vasopressin-induced concentration contractions were measured. RESULTS: Vasopressin-induced concentration contraction on human GEA was independent of functional endothelium. Propofol (10(-4), 10(-3) M) attenuated the vasopressin-induced contraction in the human GEA. Diltiazem attenuated the vasopressin-induced contraction in the human GEA. ATP-sensitive potassium channel does not affect the inhibition effect of propofol on vasopressin-induced contraction CONCLUSIONS: Usual anesthetic dose of propofol does not inhibit vasopressin-induced contraction on human GEA. High dose (>10(-4) M) propofol attenuated vasopresssi-induced contraction on GEA.

OBJECTIVE: This study was conducted to elucidate the associations of HLA with systemic sclerosis (SSc) in Koreans. METHODS: HLA associations with SSc according to SSc-specific autoantibody status and clinical subsets (diffuse and limited) were investigated. HLA-A, B, and C antigens were typed by the serological method using microlymphocytotoxicity test, and HLA-DR by DNA typing method using PCR-reverse hybridization and PCR-SSCP in 56 Korean patients with SSc and 226 healthy controls. For SSc patients, anti-Scl-70 and anicentromere antibodies were tested by double immunodiffusion and indirect immunofluorescence, respectively. RESULTS: The results of HLA class I antigen typing showed that the frequencies of HLA-A24, B52 and B62 were increased, whereas those of A33, B44 and B58 were decreased in SSc patients compared to healthy controls. The frequency of HLA-DR2 was significantly increased, whereas that of HLA-DR13 was decreased in patients with SSc compared to controls. Among HLA-DR2 alleles, both HLA-DRB1*1501 and *1502 were increased in SSc patients compared to controls. According to clinical status, HLA-DRB1*1501 was increased in limited SSc patients and that of DRB1*1502 was increased both in diffuse and limited SSc patients compared to controls. According to autoantibody status, HLA- DRB1 1502 was significantly increased in anti-Scl-70-positive SSc patients and that of DRB1 1501 was increased in anti-Scl-70-negative SSc patients compared to controls. The association of HLA-DR2 alleles with SSc according to clinical subsets and anti-Scl-70 antibody status revealed that the frequency of HLA- DRB1 *1501 was significantly increased in anti-Scl-70-negative limited SSc patients compared to controls. CONCLUSIONS: These results suggest that different HLA-DR2 alleles are associated with different types of SSc in Koreans. HLA-DRB1 1502 shows strong association with anti-Scl-70-positive SSc, and DRB1 1501 with anti-Scl-70-negative limited SSc. It is concluded that the pathogenesis of SSc in Koreans is in part, based on the same genetic background.

Tailgut cysts are rare congenital lesions. They are believed to develop from remnants of the embryonic hindgut. Malignancy in tailgut cyst is extremely unusual. We experienced a case of a carcinoid tumor arising within a tailgut cyst at the presacral space. A 40-year-old woman was admitted for acute anal pain. Digital rectal examination revealed a 2-cm-sized submucosal tumor in the posterior midline rectum 4 cm above the anal verge. On sigmoidoscopic examination, the overlying rectal mucosa seemed to be intact. We performed a transanal incisional biopsy. The pathological diagnosis of the tumor biopsy revealed a malignant neuroendocrine tumor. The patient underwent an abdominoperineal resection. The tumor proved to be mutilocular cysts with a solid component. The cysts were diagnosed as tailgut cysts that were lined by a variety of epithelial types, including inner columnar cells, outer cuboidal cells, and transitional cells. The solid component in the cysts was confirmed as a carcinoid tumor on microscopic examination. Six months after the operation, she was found to have liver and brain metastases.
