여러 개의 자석을 삼킨 경우 자석들이 서로 잡아당겨 압력 괴사로 인한 장폐쇄, 장천공, 누공 형성 등의 합병증을 일으킬 수 있다. 따라서 영 유아나 정신과적인 문제가 있는 큰 아이의 경우 자석이나 자석이 포함된 장난감과 같은 물건들을 멀리하고, 자석을 삼킨 경우에는 즉시 확인해 보아야 한다. 저자들은 1년 전부터 주기성 구토를 호소했던 중등도 정신지체를 가진 12세 남아에서 삼킨 장난감 자석 4개로 인해 위-십이지장 누공을 형성하였고 수술 후 호전된 1예를 치험하였기에 보고하는 바이다. If multiple magnets are ingested, the potential exists for the magnets attracting one another across the gastrointestinal tract and inducing pressure necrosis, perforation, fistula formation, or intestinal obstruction. We report the case of a 12-year-old boy who suffered from a fistulous communication between the lesser curvature of the mid-body of the stomach and the duodenal bulb, caused by 4 ingested magnets (Singing Magnets, China). The patient presented with moderate mental retardation, a one-year history of cyclic vomiting, and abdominal discomfort. We present the findings of simple abdominal radiography, esophagogastroduodenoscopy, computed tomography, and upper gastrointestinal series. An emergency exploratory laparotomy was performed, which revealed a gastroduodenal fistula. Fistula repair and the removal of 4 magnetic toys were subsequently performed. We emphasize that clinicians who care for children should be aware of the hazards of magnetic toy ingestion.

The development of small granule-containing cell in the superior cervical ganglion was studied by electron microscopic method in human fetuses ranging from 40 mm to 260 mm crown rump length (10 to 30 weeks of gestational age). At 40 mm fetus, the superior cervical ganglion was composed of clusters of undifferentiated cells, primitive neuroblasts, and unmyelinated nerve fibers together with blood vessels. At 90 mm fetus, the superior cervical ganglion consisted of neuroblasts, satellite cell, small granule-containing cells, and unmyelinated nerve fibers. Two morphological types of the small granule-containing cells in the superior cervical ganglion were first indentified at 90 mm fetus, but were rare. Type I granule-containing cell occurred in solitary and had long processes, whereas type II cells tend to appeared in clusters near the blood capillaries. The granule-containing cells were characterized by the presence of dense-cored vesicles ranging from $150{\sim}300nm$ in diameter in both the cell bodies and processes. Other organelles included abundant mitochondria, rough endoplasmic reticulum, neurotubules, and widely distributed ribosomes. The granule-containing cells had long processes similar to those found in principal ganglionic cells. They could be identified by their content in dense-cored vesicles. The small granule-containing cells increased somewhat in size and number with increase of fetal age. Synaptic contacts were first found on the solitary granule-containing cell at 150 mm fetus. Synaptic contacts between the soma and processes of type I granule-containing cells and preganglionic axon terminals were observed. In addition, synaptic junctions between the processes of granule-containing cells and presumed dendrite of postganglionic neuron were also observed from 150 mm onward. On the basis of these features type I granule-containing cells could be considered as interneurons. The clusters of type II granule-containing cells were located in the interstitial or subcapsular portions of the ganglion, and had short processes which ended in close relation to fenestrated capillaries. Therefore it may be infer that clusters of type II granule-containing cells have an endocrine function.

Purpose: Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, and this accounts for 38% of all patients with nosocomial infections. Despite the advances in techniques and knowledge to prevent infection, SSI remains a significant source of postoperative morbidity and mortality, and it results in a prolonged hospital stay and increased cost. This study aims to assess the incidence of SSI and to identify the risk factors associated with SSI for patients who undergo abdominal operation. Methods: The data on 347 abdominal operations that were done under general anesthesia from 1 August 2005 to 31 July 2006 was collected and reviewed. Results: The overall incidence of SSI was 4.9%. Comorbidity was the independent risk factor for the development of SSI (P=0.011). The development of SSI was related with the American Society of Anesthesiologists (ASA) preoperative assessment score (P=0.025). The duration of the operation had a statistically significant association with an increased risk of SSI on univariate analysis. The wound classification was not associated with SSI. Staphylococcus aureus was the most frequently isolated organism, and all of the cases were methcillin-resistant Staphylococcus aureus. Conclusion: This study demonstrate that comorbidity is a significant independent risk factor for SSI.
