Archives of Plastic Surgery 2021;48(1):133-143
Background:
Extensive research has been conducted on islet transplantation as a possible cure for diabetes. Islet transplantation in the liver via the portal vein has shown remarkable results, but numerous other recipient sites are currently being investigated. We aimed to show the effectiveness of using a muscle flap as a recipient site for islet transplantation.
Methods:
Islet cells were harvested from 12 isogenic Lewis rats, and then diabetes was induced in another 12 isogenic Lewis rats by streptozotocin injection. In six rats, 3,000 islets were transplanted into gastrocnemius muscle flaps, and in the other six rats, the same number of islets were transplanted into the gastrocnemius muscle. The transplanted islet cell function between the two groups was compared by means of blood glucose tests, glucose tolerance tests, immunohistochemistry, and real-time reverse transcription polymerase chain reaction.
Results:
In the muscle flap group, blood glucose levels significantly decreased after islet transplantation. Blood glucose levels were significantly different between the two groups at 3 weeks after transplantation. The muscle flap group showed nearly normoglycemic results upon the glucose tolerance test, whereas the muscle group was hyperglycemic. Immunohistochemical evaluation showed positive results against insulin and glucagon in biopsies of both groups, and the islet cell density was higher in the muscle flap group. There were no statistically significant differences between the two groups in real-time reverse transcription polymerase chain reaction results.
Conclusions
Our results suggest that muscle flaps are promising candidates for islet cell transplantation.
5.Endoscopic slide-in orbital wall reconstruction for isolated medial blowout fractures
Archives of Craniofacial Surgery 2020;21(6):345-350
Background:
This study evaluated the efficacy of the endoscopic medial orbital wall repair by comparing it with the conventional transcaruncular method. This surgical approach differs from the established endoscopic technique in that we push the mesh inside the orbit rather than placing it over the defect.
Methods:
We retrospectively reviewed 40 patients with isolated medial orbital blowout fractures who underwent medial orbital wall reconstruction. Twenty-six patients underwent endoscopic repair, and 14 patients underwent external repair. All patients had preoperative computed tomography scans taken to determine the defect size. Pre- and postoperative exophthalmometry, operation time, the existence of diplopia, and pain were evaluated and compared between the two methods. We present a case showing our procedure.
Results:
The operation time was significantly shorter in the endoscopic group (44.7 minutes vs. 73.9 minutes, p= 0.035). The preoperative defect size, enophthalmos correction rate, and pain did not significantly differ between the two groups. All patients with preoperative diplopia, eyeball movement limitation, or enophthalmos had their symptoms resolved, except for one patient who had preexisting strabismus.
Conclusion
This study demonstrates that endoscopic medial orbital wall repair is not inferior to the transcaruncular method. The endoscopic approach seems to reduce the operation time, probably because the dissection process is shorter, and no wound repair is needed. Compared to the previous endoscopic method, our method is not complicated, and is more physiological. Larger scale studies should be performed for validation.

Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin-1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-alpha release from IL-2-activated T-cells. A 13-year-old male patient visited our hospital with abdominal pain. He was diagnosed with acute lymphoblastic leukemia(T cell type) by bone marrow study on his 2 nd day in hospital. On the 3 rd day of induction chemotherapy(prednisone, L-asparaginase, vincristine, intrathecal methotrexate), pulmonary edema and pleural effusion, ascites and generalized edema developed and lasted for 53 days without responding to supportive care. The laboratoy finding was that TNF-alpha was increased without evidence of infection and hypoalbuminemia was noted. It was suggested that the patient's clinical feature was induced by VLS.

Eosinophilia is a common finding in premature babies during the neonatal period. Serial eosinophil counts were determined in 94 hospitalized, appropriately grown premature in fants whose gestational ages ranged form 28 to 36 weeks. The incidence, severity and etiologic factors of eosinophilia were retrospectively studied in premature infants, who were divided into three groups according to their gestational age. The results were as follows: 1) Absolute eosinophilia (>700/mm3)was documented in 46.8%(44/94). 2) The duration of TRN and antibiotics was cignificantly higher in infants with eosinophilia than withour eosinophilia (p<0.05). The gestational age of the infants with eosinophilia was significantly shorter than that of the infants without eosinophilia (p<0.05). The infants with eosinophilia started with bottle feeding significantly earlier than the infants without eosinophilia (p<0.05). 3) The infants younger than 30 weeks of gestational age have greater incidence of eosinophilia (75%) than the infant with the gestational age between 34 and 36 weeks (34.3%)(p<0.05). 4) The incidence of mild eosinophilia was higher in the group with gewtational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05).Also, the incidence of severe eosinophilia was significantly higher in the group with gestational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05). 5) Eosinophilia was more prevalent in the infants who received parenteral nutrition composed of glucose, amino acid and lipid(77.8%) than the infants who received only glucose(34.1%)(p<0.05). 6) Gestational age and birth weight were significantly lower in infants with severe eosinopilia than those of mild or moderate eosinophilia. The duration of TRN and antibiotics were significantly longer in infants with severe eosinophilia than those of mild or moderate eosinophilia (p<0.05). 7) The peak eosinophil count was observed significantly later in severe eosinophilic group (26.5 13.1 days)than in non-eosinophilic group(14.4 9.0 days)(p<0.05). The above results suggest that eosinophilia in premature infants may be the effecto of immature immunologic responses to the intravenous administration of extemal antigens like amino acid, lipid and antibiotics.

8.Median and Paramedian Craniofacial Cleft.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2000;27(2):159-164
Craniofacial clefts are rare, mysterious and variable congenital anomalies. The incidence of craniofacial clefts is at least 1 per 100,000 live births. The cause of craniofacial clefts remains obscure, and attempts to classip craniofacial clefts are replete with problems. Tessier presented his classification in 1973 and used the orbit to distinguish the facial clefts from the cranial clefts. He noted that those lesions that involve both the face and cranium tend to do so in a consistent, predictable fashion. The clefts are numbered from 0 to 14 and are oriented around the orbit like spokes of a wheel. Van der Meulen proposed a classification in 1983 on an embryologic basis. The term dysplasia was used instead of cleft, since some of the malformations do not represent true clefts. Between 1997 to 1998, authors experienced 3 cases of median and paramedian facial cleft. One was No.2 facial cleft and the others were No.0-14 facial cleft with orbital hypertelorism. Their ages ranged from 1 to 5 years.

Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.
