Opioid-induced rigidity is a potentially life-threatening complication that can occur after treatment with large doses of opioids, but with early recognition it can be treated effectively with naloxone or with muscle relaxants. Regarding its onset time, there have been few case reports that have described delayed manifestations of opioid-induced rigidity. The mechanism of this complication is not well understood. In this report we describe a case of incidental overdose injection of sufentanil and subsequently review the confusing clinical features that require immediate diffenrentiation and the possible mechanim of this complication.

Background: The ideal absorbable plating system should provide sufficient rigidity and then be absorbed within a timely manner. The Resorb-X has been recently developed as a plating system with a mixture ratio of 50:50 poly(D, L-lactide). Methods: We present seven of 121 patients who experienced delayed degradation with this absorbable plate. One hundred twenty-one patients with facial bone fracture underwent surgical treatment from March 2011 to March 2015, and rigid fixation was achieved with the Resorb-X. Results: Of 121 patients, seven (5.8%) developed complications at the surgical sites. Six of 102 cases underwent fixation of the infraorbital rim and one of 73 underwent fixation of the frontozygomatic buttress; the other sites of fixation did not develop delayed degradation. Foreign body granuloma developed at the earliest by postoperative 20 months and at the latest by postoperative 28 months (average, 23.5 months). Conclusion: We observed that the use of absorbable plates in incision sites or areas with thin skin can increase the possibility of delayed degradation. When performing surgery in these areas, the normal skin above the fixed location should be covered sufficiently.

Objectives : This study was designed to investigate significant differences between the first attack and reattack groups to form fundamental data for decreasing recurrence and secondary prevention of stroke. Methods : I studied 204 patients admitted within 7 days of onset, after the diagnosis of stroke, in the Oriental Medical Hospital of Dongeui University from February to July in 2001.compared the reattack group with the first attack group for risk factors, clinical symptoms and progress, average mark and degree of improvement in Activity Index. Results : 1. Meaningful risk factors associated with the reattack group were male sex, a past history of hypertension and transient ischemic attack, and a family history of stroke. 2. The reattack group had conscious or cognitive disorder in early stage of onset, dysphagia, constipation, urinary incontinence, visual field defect in acute stage, high blood pressure and tachycardia in abnormalvital sign in acute stage, neuropsychosis, shoulder pain and rigidity, and pneumonia in complications more than the first attack group. 3. In Activity Index, the average mark of reattack group was lower than that of the first stroke group and improvement of the reattack group was delayed compared with the first attack group. Conclusions : The reattack group had more severe symptoms and clinical progress than the first attack group.

A 12-year-old, female Maltese was referred with uncontrolled hyperadrenocorticism (HAC). Despite well management of HAC through treatment with trilostane and serial monitoring with ACTH stimulation tests for over three years, stiffness of the neck and limbs progressively worsened over time. Neurological test was performed, which showed no abnormalities of cranial nerves. Proprioception was delayed but the cause appeared to be due to stiffness of limb muscles. Muscle tone had increased over time and stiffness had worsened to the extent where it made walking difficult. MRI scans showed no orthopedic or spinal diseases, and pituitary microadenoma was confirmed with pituitary gland measurement of 6 × 6.4 × 4.5 mm (H × W × L). Electromyography presented random discharges with fluctuating amplitude and frequency, which were consistent with myotonic discharges. There were no improvements of myotonic signs despite treatment for HAC with trilostane. Supplementation of L-carnitine and coenzyme Q-10 to mitigate muscle stiffness, following diazepam and methocarbamol to help with muscle rigidity, failed to show any positive effect and the dog died a sudden death, 1,182 days after the initial visit.

Pilon fractures involving distal tibia remain one of the most difficult therapeutic challenges that confront the orthopedic surgeons because of associated soft tissue injury is common. To introduce and describe the diagnosis, current treatment, results and complications of the pilon fractures. In initial assessment, the correct evaluation of the fracture type through radiographic checkup and examination of the soft tissue envelope is needed to decide appropriate treatment planning of pilon fractures. Even though Ruedi and Allgower reported 74% good and excellent results with primary open reduction and internal fixation, recently the second staged treatment of pilon fractures is preferred to orthopedic traumatologist because of the soft tissue problem is common after primary open reduction and internal fixation. The components of the first stage are focused primarily on stabilization of the soft tissue envelope. If fibula is fractured, fibular open reduction and internal fixation is integral part of initial management for reducing the majority of tibial deformities. Ankle-spanning temporary external fixator is used to restore limb alignment and displaced intraarticular fragments through ligamentotaxis and distraction. And the second stage, definitive open reduction and internal fixation of the tibial component, is undertaken when the soft tissue injury has resolved and no infection sign is seen on pin site of external fixator. The goals of definitive internal fixation should include absolute stability and interfragmentary compression of reduced articular segments, stable fixation of the articular segment to the tibial diaphysis, and restoration of coronal, transverse, and sagittal plane alignments. The location, rigidity, and kinds of the implants are based on each individual fractures. The conventional plate fixation has more advantages in anatomical reduction of intraarticular fractures than locking compression plate. But it has more complications as infection, delayed union and nonunion. The locking compression plate fixation provides greater stability and lesser wound problem than conventional implants. But the locking compression plate remains poorly defined for intraarticular fractures of the distal tibia. Active, active assisted, passive range of motion of the ankle is recommended when postoperative rehabilitation is started. Splinting with the foot in neutral is continued until suture is removed at the 2~3 weeks and weight bearing is delayed for approximately 12 weeks. The recognition of the soft tissue injury has evolved as a critical component of the management of pilon fractures. At this point, the second staged treatment of pilon fractures is good treatment option because of it is designed to promote recovery of the soft tissue envelope in first stage operation and get a good result in definitive reduction and stabilization of the articular surface and axial alignment in second stage operation.

Malignant hyperthermia is a catastrophic, hypermetabolic syndrome that arises in susceptible individuals when they are exposed to certain inhalational anesthetics or muscle relaxants. It is characterized by hyperthermia, tachycardia, acidosis, and muscle rigidity. It has been noted that the majority of cases of malignant hyperthermia are fatal unless early diagnosis and treatment are performed. We experienced a 24 year old male Malignant hyperthermia presented for orthognathic surgery under $O_2-N_2O$-sevoflurane anesthesia without succinylcholine. Two half hours after induction, tachycardia developed and was followed by unstable blood pressure and hyperpyrexia. Anesthesia was terminated and vigorous emergency treatment was attempted. The patient was treated by the intravenous administration of dantrolene sodium. The diagnosis of an acute malignant hyperthermia reaction by clinical criteria can be difficult because of the nonspecific nature and variable incidence of many of the clinical signs and laboratory findings. So the malignant hyperthermia clinical grading scale is recommended for use as an aid to the objective definition of this disease. This clinical grading system provides a new and comprehensive clinical case definition for the malignant hyperthermia syndrome. We recently encountered a case of delayed malignant hyperthermia during sevoflurane anesthesia that was successfully treated by the intravenous administration of dantrolene sodium. In conclusion, exposure to sevoflurane should be avoided in patients thought to be susceprible to malignant hyperthermia.

Purpose: The purpose of this study was to investigate usefulness of locking compression plate (LCP) as an open reduction technique by evaluating clinical results obtained from the patients with lateral malleolar fracture treated by internal fixation using LCP after open reduction. Materials and Methods: Among the patients with lateral malleolar fracture, the 28 patients who were treated by internal fixation using Locking compression plate after an open reduction and were able to be followed up for more than 6 months were included in this study. Final postoperative evaluation was done based on the Meyer's clinical and radiologic evaluation system. Results: All cases achieved anatomical reduction and fixation of the reduction postoperatively. 28 minutes were taken meaningly from the incision to the fixation of LCP plate after the anatomical reduction. Everage bony union time was 8.2 weaks, and the result was excellent in 23 cases (82%), good in 5 cases (17%) and poor result was abscent according to the criteria of Meyer et al. One case of post traumatic arthritis and one case of superficial infection on the operation site were found, but non-union, delayed union and malunion were not occurred. Conclusion: The internal fixation after open reduction using LCP is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including easy application and a greater stability due to its capability of maintaining exact anatomical reduction even though the screw does not penetrate the medial cortex of fibular to add the stability and rigidity of the fixation.

Glucose transporter type 1 (GLUT1) deficiency syndrome (DS) is a metabolic brain disorder caused by a deficiency resulting from SLC2A1 gene mutation and is characterized by abnormal brain metabolism and associated metabolic encephalopathy. Reduced glucose supply to the brain leads to brain damage, resulting in delayed neurodevelopment in infancy and symptoms such as eye abnormalities, microcephaly, ataxia, and rigidity. Treatment options for GLUT1 DS include ketogenic diet (KD), pharmacotherapy, and rehabilitation therapy. Of these, KD is an essential and the most important treatment method as it promotes brain neurodevelopment by generating ketone bodies to produce energy. This case is a focused study on intensive KD nutritional intervention for an infant diagnosed with GLUT1 DS at Gangnam Severance Hospital from May 2022 to January 2023. During the initial hospitalization, nutritional intervention was performed to address poor intake via the use of concentrated formula and an attempt was made to introduce complementary feeding. After the second hospitalization and diagnosis of GLUT1 DS, positive effects on the infant's growth and development, nutritional status, and seizure control were achieved with minimal side effects by implementing KD nutritional intervention and adjusting the type and dosage of anticonvulsant medications. In conclusion, for patients with GLUT1 DS, it is important to implement a KD with an appropriate ratio of ketogenic to nonketogenic components to supply adequate energy. Furthermore, individualized and intensive nutritional management is necessary to improve growth, development, and nutritional status.

본 연구에서는 보통포틀랜드 시멘트(이하 OPC)제조과정의 분쇄공정 중 밀출구에서 배출되는 비교적 가격이 저렴하면서, 수화열면으로도 효과일 것으로 예상되는 입자분포를 갖는 시멘트(이하 CC)를 대상으로 플라이애시(이하 FA)와 고로슬래그 미분말(이하 BS)를 복합치환하는 3성분계 저발열 시멘트로의 개발 가능성을 검토하기 위하여 유동성, 강도, 간이단열온도 상승량 등 기초적인 특성에 대하여 분석하고자 한다. 실험결과로 유동성은 CC의 치환율이 증가함에 따라 저하하는 경향을 보였고, FA+BS의 치환율이 늘어남에 따라 증가하는 경향을 나타냈다. 공기량은 CC의 치환율이 증가함에 따라 미소하게 감소하는 경향을 나타냈고, FA+BS의 치환율이 증가함에 따라 감소하였다. 응결특성으로 CC 및 FA+BS의 치환율이 증가 할수록 응결 시간은 지연되었다. 간이 단열에 의한 온도 상승량은 전반적으로 CC 치환율이 증가할수록, FA+BS의 치환율이 증가할수록 피크온도는 감소하였고, 이후 온도저하가 완만해 지는 경향을 나타냈다. 압축강도는 CC 및 FA+BS 치환율이 증가할수록 저하하였는데, 재령이 경과함에 따라 장기강도는 Plain과 동등하거나 동등 이상의 강도를 발현 하였다. 종합적으로 CC에 FA+BS를 치환하였을 때 유동성 및 공기량은 저하하는 경향을 나타냈으나, 수화열 면에서 양호한 저감효과를 보여 3성분계 저발열 시멘트로의 개발이 가능성할 것으로 사료된다.
