We evaluated sixteen patients of traumatic diaphragmatic injuries that we have experienced from Jan. 1987 to Aug 1993. Age was ranged from 6 to 71 years, predominantly in the fourth and fifth decades. 13 were male and 3 were female, a ratio of 4.3: 1. Blunt trauma was develped in 11 [Lt 7, Rt 4], penetrating trauma in 5 [Lt 2, Rt 3]. Preoperative diagnosis of diaphragmatic injury was possible in 8 patients [72.2 %] in blunt trauma, and 1 patient [20 %] in penetrating trauma. 8 cases[54.5%] in blunt trauma, and 4 cases in penetrating trauma were treated within 24 hours,meanwhile, patients treated after 10 days were 3, all by blunt trauma.The repair of 16 cases were performed with thoracic approach in 4 cases, thoracoabdominal approach in 3 cases, and abdominal approach in 9 cases. The herniated organs in thorax were stomach [5], colon [3], liver [2], and pancreas [1]. Postoperative complication were developed in 9cases[56.3%] significantly related with delayed operation time [p < 0.01 ]. Hospital mortality was 12.5 % [2/16], and the causes of death were hypovolemic shock in one and hepatic failure due to portal vein rupture in another.

Malaria is a tropical disease caused by protozoans of the Plasmodium genus. Delayed diagnosis and misdiagnosis are strongly associated with higher mortality. In recent years, a greater importance is attributed to Plasmodium knowlesi, a species found mainly in Southeast Asia. Routine parasitological diagnostics are associated with certain limitations and difficulties in unambiguous determination of the parasite species based only on microscopic image. Recently, molecular techniques have been increasingly used for predictive diagnosis. The aim of the study is to draw attention to the risk of travelling to knowlesi malaria endemic areas and to raise awareness among personnel involved in the therapeutic process.

Currently, Hyphantira cunea Drury, the fall webworms (FWW), is one of the most severe insect pest for various landscaping trees and mulberry trees. In this study, we investigated whether FWW might be managed by Sodium saccharin (SAC) which is a food additive and not toxic to humans and environment. We found that FWW larvae treated with various concentrations of SAC showed dose-dependent delayed development and low survival rates. The lethal-concentration 50% of FWW larvae to SAC was 0.03 M. We also confirmed that SAC can be used to control FWW larvae attacking mulberry trees in the field. Compared to not-treated or tap-water-spraying control groups, SAC-spraying groups showed significantly higher mortality rates of FWW larvae (56.2%). Thus, SAC can be used for control FWW larvae in mulberry trees.

Objectives: Low birth weight (LBW) is a major public health concern, especially in developing countries, and is frequently related to child morbidity and mortality. This study aimed to identify key determinants that influence the prevalence of LBW in selected developing countries. Methods: Secondary data analysis was conducted using 10 recent Demography and Health Surveys from developing countries based on the availability of the required information for the years 2010 to 2013. Associations of demographic, socioeconomic, community-based, and individual factors of the mother with LBW in infants were evaluated using multivariate logistic regression analysis. Results: The overall prevalence of LBW in the study countries was 15.9% (range, 9.0 to 35.1%). The following factors were shown to have a significant association with the risk of having an LBW infant in developing countries: maternal age of 35 to 49 years (adjusted odds ratio [aOR], 1.7; 95% confidence interval [CI], 1.2 to 3.1; p<0.01), inadequate antenatal care (ANC) (aOR, 1.7; 95% CI, 1.1 to 2.8; p<0.01), illiteracy (aOR, 1.5; 95% CI, 1.1 to 2.7; p<0.001), delayed conception (aOR, 1.8; 95% CI, 1.4 to 2.5; p<0.001), low body mass index (aOR, 1.6; 95% CI, 1.2 to 2.1; p<0.001) and being in the poorest socioeconomic stratum (aOR, 1.4; 95% CI, 1.1 to 1.8; p<0.001). Conclusions: This study demonstrated that delayed conception, advanced maternal age, and inadequate ANC visits had independent effects on the prevalence of LBW. Strategies should be implemented based on these findings with the goal of developing policy options for improving the overall maternal health status in developing countries.

Objectives : This experimental research has been done to study the effects of herbal-acupuncture with Juglandis Semen on the anti-allergic reaction. Methods : ICR mice were injected intraperioneally with compound 48/80 to induce the immediately type hypersensitivity (anaphylaxis). ICR mice were sensitized by PC and SRBC to induce the delayed type hypersensitivity. Sprage-Dawley rats were injected subcutaneously with egg albumin to measure the WBC. ICR mice and Sprage-Dawley rats were injected with Juglandis Semen herbal-acupuncture for the anti-allergic reaction test. Results : 1. In the restraint effect of systemic anaphylactic reaction, the mortality of mice decreased 20% each before 10 minutes and after 5 minutes. 2. In the contact dermatitis induced by PC, both Treat Ⅰand Treat Ⅱ group showed significant(p<0.01, p<0.05) decrease in comparison with the Control group, and also Treat Ⅲ group showed significance(p<0.005). 3. In the delayed type hypersensitivity in mice challenged by SRBC, Treat Ⅰ group showed significant(p<0.05) decrease in comparison with the Control group, and there was significance(p<0.05, p<0.05) in Treat Ⅲ and Treat Ⅳ group. 4. The change of the WBC in allergic rats induced by egg albumin showed significant(p<0.01, p<0.05, p<0.05) decrease in Treat Ⅰ, Treat Ⅱ and Treat Ⅲ group. Conclusions : The restraint effects of Juglandis Semen herbal-acupuncture on the anti-allergic reaction showed significance statistically. And also allergic group treated with $BL_{17}$ acupuncture (Treat Ⅲ group) showed same results.

Immunostimulating effects of fucoidan administration to rockfish Sebastes schlegelii at a concentration of 20 g/kg of diet were evaluated under high water temperature condition. The oral administration of fucoidan mixed with feed at a concentration of 20 g/kg of diet for 2 weeks increased the interleukin 1β gene in the intestine and kidney of fish by 5.7 and 6.3 times, respectively. In addition, when the water temperature was gradually increased from 24 to 31.4℃ for 2 weeks, LT₅₀ delayed by 24 h in the fucoidan treated group compared to that in the control group, and mortality also reduced. Streptococcus iniae infection at a concentration of 1.50×10⁰ CFU/fish at 28℃ delayed LT₅₀ by 12 h in the fucoidan-treated group. Furthermore, the overall survival rate was 0% in the control group and 20% in the fucoidan-treated group. This study confirmed the applicability of dietary additives such as fucoidan as an immune activator of rockfish under high temperature condition.

Background: This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or nonoperative management at our major trauma center. Methods: A retrospective review of all patients who were considered for surgical stabilization of rib fractures (SSRF) at a single major trauma center from May 2016 to September 2022 was performed. Results: In total, 352 patients with complex rib fractures were identified. Thirty-seven patients (11%) fulfilled the criteria for surgical management and underwent SSRF. The SSRF group had a significantly higher proportion of patients with flail chest (32 [86%] vs. 94 [27%], p<0.001) or Injury Severity Score (ISS) >15 (37 [100%] vs. 129 [41%], p<0.001). No significant differences were seen between groups for 1-year mortality. Patients who underwent SSRF within 72 hours were 6 times less likely to develop pneumonia than those in whom SSRF was delayed for over 72 hours (2 [18%] vs. 15 [58%]; odds ratio, 0.163; 95% confidence interval, 0.029-0.909; p=0.036). Prompt SSRF showed non-significant associations with shorter intensive care unit length of stay (6 days vs. 10 days, p=0.140) and duration of mechanical ventilation (5 days vs. 8 days, p=0.177). SSRF was associated with a longer hospital length of stay compared to nonoperative patients with flail chest and/or ISS >15 (19 days vs. 13 days, p=0.012), whilst SSRF within 72 hours was not. Conclusion: Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Delayed surgical fixation was associated with increased rates of pneumonia and a longer hospital length of stay.

Mortality associated with maxillofacial infection is relatively low due to the development of antibiotics, and improved oral care. However, inappropriate treatment, delayed treatment, old age, underlying systemic disease, and drug-resistant microorganisms can potentially result in life threatening situations such as cavernous sinus thrombosis, mediastinitis, and sepsis. Sepsis is the most dangerous state with high mortality, ranging from 20~60%. The treatment of sepsis involves properly monitoring vital functions, fluid resuscitation, surgical drainage, and empirical use of high doses of antibiotics until culture results are available. Ventilatory support maybe be required as well. We encountered a 64-year-old patient who died from sepsis that developed as the result of an odontogenic infection. The initial diagnosis was right temporal, infraorbital, buccal, pterygomandibular space abscess. Despite surgical and medical supportive care, the condition progressed to sepsis and after four days the patient died due to multiple organ failure.

Status epilepticus is the most common serious neurological condition triggered by abnormal electrical activity, leading to severe and widespread cell loss in the brain. Lithium has been one of the main drugs used for the treatment of bipolar disorder for decades, and its anticonvulsant and neuroprotective properties have been described in several neurological disease models. However, the therapeutic mechanisms underlying lithium's actions remain poorly understood. The muscarinic receptor agonist pilocarpine is used to induce status epilepticus, which is followed by hippocampal damage. The present study was designed to investigate the effects of lithium post-treatment on seizure susceptibility and hippocampal neuropathological changes following pilocarpine-induced status epilepticus. Status epilepticus was induced by administration of pilocarpine hydrochloride (320 mg/kg, i.p.) in C57BL/6 mice at 8 weeks of age. Lithium (80 mg/kg, i.p.) was administered 15 minutes after the pilocarpine injection. After the lithium injection, status epilepticus onset time and mortality were recorded. Lithium significantly delayed the onset time of status epilepticus and reduced mortality compared to the vehicle-treated group. Moreover, lithium effectively blocked pilocarpine-induced neuronal death in the hippocampus as estimated by cresyl violet and Fluoro-Jade B staining. However, lithium did not reduce glial activation following pilocarpine-induced status epilepticus. These results suggest that lithium has a neuroprotective effect and would be useful in the treatment of neurological disorders, in particular status epilepticus.

외상에 의한 심장 손상은 드물게 발생하지만 진단 및 치료가 지연되었을 경우 치사율이 매우 높다. 이에 본원에서는 외상성 심장 손상 환자를 대상으로 후향적 연구를 진행하였다. 대상 및 방법: 1995년 3월부터 2002년 7월까지 본원 응급실을 통하여 내원한 외상성 심장 손상 환자 대상으로 하였다. 총 17명의 환자 중 흉기 등에 의한 자상이 5예, 둔상 중에서 교통사고로 인한 손상이 7예, 작업장 등에서 추락한 경우가 4예, 원인을 알 수 없는 경우가 있었다. 모든 예에 있어서 응급 수술을 진행하였고, 6예의 경우 심폐기를 이용한 수술을 진행하였다. 결과: 수술 후 4예의 사망이 있었다. 수술 후 모든 환자는 중환자실로 이송하였고 평균 중환자실 재원기간은 3.86$\pm$3.35일, 평균 총재원기간은 18.27$\pm$14.99일이었다. 응급실에 도착하여 수술의 진행까지 생명 징후가 비교적 안정적이었던 경우 사망한 예는 없었다. 결론: 수술 전의 환자의 상태는 환자의 예후에 직접적인 영향을 주는 중요한 인자이기 때문에 흉부외상 환자에게 있어서 심장손상 여부의 판단은 매우 중요하다.
