Mazabraud syndrome (MS) is a rare and sporadic disorder. It is mainly characterized by fibrous dysplasia (FD) of single or multiple bones and intramuscular myxomas (IM). Data on the prevalence since it was first reported, clinical features, and prognosis are extremely scarce. We report a case of a 59-year-old woman with IM and polyostotic FD. She also had multiple cafe’-au-lait spots suggestive of McCune-Albright syndrome (MAS). On magnetic resonance imaging, there are masses with well-defined heterogeneous enhancement, accompanied by an inner cyst in the vastus lateralis muscle and femur. These radiological results are identical to those of FD. After surgical intervention with excision of intramuscular soft-tissue mass, a diagnosis of IM of MS was confirmed. Given that cafe’-au-lait spots also appeared, the patient was diagnosed with a variant of MS with some of the clinical characteristics of MAS.

Objective: The purpose of this study was to investigate the effects of remifentanil concentration during total intravenous anesthesia changes on propofol requirements, vital signs, wake-up time, and postoperative pain.Methods: After induction of anesthesia, the concentration of remifentanil was divided into 2 ng/mL (R2 group) and 6 ng/mL (R6 group). In each group, the propofol concentration for maintaining a bispectral index (BIS) of 40–50, systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, time from drug discontinuation to eye opening, and pain score in the recovery room were all measured using the Student t-test. Differences between the two groups were verified for statistical significance.Results: The average BIS scores maintained during the time of measurement were 45.0±3.8 and 45.5±3.9 in the R2 and R6 groups, respectively. The effective concentrations of propofol to maintain these corresponding BIS scores were 3.0±0.6 mcg/mL and 2.4±0.7 mcg/mL in the R2 and R6 groups, respectively.Conclusion: On using propofol and remifentanil during total intravenous anesthesia, the R6 group showed a reduction in the amount of propofol required to maintain a constant BIS, as well as reduced intraoperative blood pressure and pulse compared to those in the R2 group. No significant effects were observed in the time taken for the patient to wake up postoperatively and in postoperative pain experienced by the patient.

Chondrolipoma is rare and is mainly encountered in large-sized, long-standing lipomas. Chondrolipoma can be found at almost any site of the body, particularly in the connecting tissue of the skeletal system, breast, pharynx, and nasopharynx. A small number of chondrolipomas have been reported in the literature with rare magnetic resonance examples available. Here, we report a rare case of chondrolipoma in the shoulder and review its radiographic and pathologic correlation. This paper aims to report plain radiograph, computed tomography, and magnetic resonance examples of chondrolipoma

Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that persists for more than 2 weeks and requires insulin therapy. NDM principally occurs before 6 months of age. Transient NDM (TNDM) is a clinical form of NDM that persists for a median of 12 weeks and resolves completely by 18 months. However, it may relapse as type 2 DM during early adulthood. The major causes of TNDM are mutations in chromosome 6q24 or the KCNJ11 or ABCC8 genes; the latter encode the two subunits of the pancreatic adenosine triphosphate (ATP)-sensitive potassium channel (KATP-channel). This condition responds well to oral sulfonylurea therapy. Herein, we report a neonate who was small for gestational age and exhibited TNDM symptoms. Genetic analysis revealed a nonspecific mutation in ABCC8; he was successfully treated with oral sulfonylurea.

Endoluminal reconstruction of an intracranial aneurysm using flow-diverting devices, such as the pipeline embolization device (PED), is a new treatment modality with good clinical outcomes. The device was originally indicated for challenging cases, such as wide-necked large or giant aneurysms, and is gaining popularity as a reliable treatment for nearly all intracranial aneurysms. The overall complication rate of flow-diverting devices use is 17.0%, including occlusion of side-branching or perforating arteries, rerupture of the aneurysm, in-stent thrombosis, and, rarely, stent migration. We report a rare complication of the PED: delayed migration of the PED after successful stent implantation during treatment of an unruptured vertebral artery dissecting aneurysm, which resulted in rupture of the aneurysm. Further, we discuss technical steps that can be taken to prevent this potential complication.

Catastrophic carbon dioxide (CO2) embolism is a rare, but potentially life-threatening, the complication of laparoscopic gynecologic surgery. We report the case of a healthy 53-year-old woman who developed CO2 embolism and cardiac arrest during laparoscopic surgery. She had a history of two cesarean sections and had extensive peritoneal adhesions. After placement of the trocar and insufflation of CO2, end-tidal CO2 dropped from 35 to 15 mm Hg, and the patient had a cardiovascular collapse. In this patient, CO2 embolism was diagnosed on the basis of a sudden decrease in end-tidal CO2, hypotension, and hypoxemia. The patient was managed quickly and aggressively. The patient recovered completely following the treatment for CO2 embolism, with no cardiopulmonary or neurological sequelae. There is an increased risk of catastrophic CO2 embolism during laparoscopic gynecologic surgery in patients with previous abdominal surgery. Therefore, the surgeon and anesthesiologist should remain vigilant to promote early detection of CO2 embolism.

Magnetic resonance imaging (MRI) is a useful and safe imaging modality for examining preterm infants. However, MRI examination requires careful precautions, and infants and children are likely to require deep sedation or anesthesia to keep them still during the examination. Sedation has various risks and the greatest concern of sedation is cardiorespiratory events. In addition, delicate titration is also necessary for preterm infants because propofol pharmacokinetics is different from those in older children. We successfully completed sedation of a preterm neonate (gestational age, 32+1 weeks; birth weight, 1,970 g) with a history of frequent apnea through careful assessment and continuous monitoring. We want to suggest alternative options for airway management of the high risk of respiratory complications.

A key challenge of anesthesia is to provide patients with safe and optimized anesthetic management to improve prognosis and minimize mortality and morbidity. To this end, the anesthesiologist should comprehensively understand the patient’s physical status through pre-anesthetic assessment and carefully monitor the patient during surgery. Several types of novel patient-monitoring devices may be useful to achieve this purpose. We report a case of anesthetic management in a patient with left internal carotid artery occlusion and penetrating aortic ulcer.

Jehovah’s Witnesses refuse blood transfusions according to religious beliefs, and for this reason, most hospitals and doctors have refused their treatment. There are more than 100,000 religious people in Korea, but there are few bloodless centers that can receive their treatment. So, the number of Jehovah’s Witnesses patients visiting bloodless centers in Soonchunhyang University Bucheon Hospital has been increasing every year. Despite this situation, no legal or medical countermeasure has yet been proposed against them. Therefore, I would like to take a bioethical approach based on “principles of biomedical ethics” and introduce “patient blood management” which is currently spreading in advanced medical countries.

Fingertip amputation is a common injury among trauma occurring in the upper extremity. After amputation of the fingertip, there are several treatment options according to the degree of damage. Also, the skin flap is sometimes performed when skin defects are accompanied. Among the complications associated with fingertip injury, cyst formation at the amputation stump is rare but some cases have been reported based on the pathologic findings. There was a case of an infected epidermal inclusion cyst containing multiple nail plates at the amputation stump of the thumb, so we would like to report it with a review of the literature.
