  • To investigate the usefulness of optical coherence tomography (OCT) for imaging lymphedema, we directly compared it to other histological methods in a mouse model of lymphedema. We performed detailed imaging of the lymphedema lesion on a mouse tail. We imaged the mouse tail in vivo with OCT and created histopathological samples. We constructed a spectrometer-based OCT system using a fiber-optic Michelson interferometer. The light was directed to 50:50 couplers that split the light into reference and sample arms. Backscattered light from a reference mirror and the sample produced an interference fringe. An OCT image of the lymphedema model revealed an inflammatory reaction of the skin that was accompanied by edema, leading to an increase in the light attenuation in the dermal and subcutaneous layers. Similar to OCT image findings, histological biopsy showed an inflammatory response that involved edema, increased neutrophils in epidermis and subdermis, and lymphatic microvascular dilatation. Furthermore, the lymphedema model showed an increase in thickness of the dermis in both diagnostic studies. In the mouse tail model of lymphedema, OCT imaging showed very similar results to other histological examinations. OCT provides a quick and useful diagnostic imaging technique for lymphedema and is a valuable addition or complement to other noninvasive imaging tools.

  • This study investigated cases of progressively necrotizing limbs in Korean indigenous calves. The recent case (Case 1) involved a 3-month old, male calf in Jeonbuk province that presented a visibly dry form of gangrene affecting joints of the forelimbs and the hind limbs. Radiograph revealed osteoarthritis possibly resulting from pressure of disrupted joint skin, fasciae, deeper underlying musculatures and tendon. Histopathology of affected tissue showed necrotizing; severely thrombosed dilated blood vessels with rechanneling microvasculatures. The lack of substantial infectious inflammatory exudates in the vital organs and the inability to respond to antimicrobial treatment bolstered the notion that the observed thromboembolic and vascular lesion was attributed to possible vasoconstrictive effects of ergot alkaloids. Case 2: A previously encountered similar case in a 4-month old, male calf showing gangrene of hind limbs and posterior ataxia was likewise presented. These two cases were impressed as probable ergotism. Ergotism may be uncommon or underreported in Korea. Future isolation of ergot alkaloids in feeds or in pasture is highly suggested.

  • Reconstruction of a full-thickness alar defect requires independent blood supplies to the inner and outer surfaces. Because of this, secondary operations are commonly needed for the division of skin flap from its origin. Here, we report a single-stage reconstruction of full-thickness alar defect, which was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. A 49-year-old female had presented with a squamous cell carcinoma of the right ala which was invading through the mucosa. The lesion was excised with a 5-mm free margin through the full-thickness of ala. The lining and cartilage was restored using a septal mucosa hinge flap and a conchal cartilage from the ipsilateral ear. The superficial surface was covered with a nasolabial island flap based on a perforator from the angular artery. The three separate tissue layers were reconstructed as a single subunit, and no secondary operations were necessary. Single-stage reconstruction of the alar subunit was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. Further studies are needed to compare long-term outcomes following single-stage and multi-stage reconstructions.

  • The immune thrombocytopenia(ITP) is defined as a platelet count of less than $100,000/{\mu}L$. It is gene rally known as characterized by the bleeding manifestations of skin and/or mucosa like ecchymosis due to low platelet count, but reports of the related intraosseous lesions are not common. The idiopathic bone cavity(IBC) is an empty space of the bone, which occurs mainly in the long bones. It is found predominantly in the mandible in case of the maxillofacial area. In general, it appears as an isolated unilocular lesion without the correlation of the teeth. Although the cause of the IBC is supposed to be associated with hemostatic problems, the etiology is unclear and it was not disclosed the relevance of specific systemic disease. In this present case, IBCs that occurred in mandible of patient who has IPT was treated by curettage with platelet transfusion.

  • Synurus deltoides was previously found to possess significant anti-inflammatory activity especially against chronic inflammation, and strong analgesic activity in vivo. In this study, new anti-inflammatory formulation containing S. deltoides extract as a major ingredient was prepared and in vivo activity was evaluated. The plausible action mechanism was also investigated. The new formulation (SAG) contains 1 part of S. deltoides extract, 0.9 part of Angelica gigas extract and 0.9 part of glucosamine sulfate (w/w). SAG inhibited dose-dependently edematic response of arachidonic acid (AA)- and 12-O-tetradecanoyl 13-acetate (TPA)-induced ear edema in mice, which is an animal model of acute inflammation. SAG showed 44.1 % inhibition of AA-induced ear edema at an oral dose of 50 mg/kg. In an animal model of chronic inflammation, SAG clearly reduced the edematic response of 7 -day model of multiple treatment of TPA (38.1 % inhibition at 200 mg/kg/day). Furthermore, SAG (50-800 mg/kg/day) as well as S. deltoides extract (285 mg/kg/day) significantly inhibited prostaglandin $E_2$ production from the skin lesion of the animals of 7-day model. These results were well correlated with in vitro finding that SAG as well as S. deltoides extract reduced cyclooxygenase (COX)-1- and COX-2-induced prostanoid production, measured in mouse bone marrow-derived mast cells. Therefore, these results suggest that SAG possesses anti-inflammatory activity in vivo against acute as well as chronic inflammatory animal models at least in part by inhibition of prostaglandin production through COX-1/COX-2 inhibition. And COX inhibition of SAG is possibly contributed by S. deltoides extract among the ingredients. Although the anti-inflammatory potencies of SAG were less than those of currently used anti-inflammatory drugs, this formulation may have beneficial effect on inflammatory disorders as a neutraceutical.

  • Purpose: Romberg's disease manifests as progressive hemifacial atrophy of the skin, soft tissue and bone, which usually begins in the first or second decade of life. When present, atrophy may originate from the cutaneous stigmata and may become so sharply delimited by the midline. Methods: A 10-year-old girl, who had suffered from right mandibular area atrophy for 3 years, visited us and was diagnosed with Romberg's disease. The depressed lesion of the face was augmented successfully using a deepithelialized groin free flap. The superficial circumflex iliac vessels were used as the donor pedicle and the facial artery and vein were used as the recipient vessels. Results: After surgery, the flap survived well and she was satisfied with the result. Although there are various methods of facial augmentation using free flaps, this flap has some advantages. First, there is a considerable amount of fat tissue components for augmentation. Second, flap elevation with thinning is possible. Third, the donor site can be hidden. Conclusion: The groin dermo-fat free flap is a good method for the facial augmentation of Romberg's disease.

  • Objectives : This study reports a 42-year old female inpatient who visited for recurrent herpes zoster on the right hand and right side of the face on 5 days after coronavirus disease 2019 (COVID-19) vaccination. She already had 2 times of herpes zoster prior to this outbreak. Methods : During 10 days of hospitalization, both treatments were simultaneously applied to her. For Korean medical treatment, acupuncture, herbal medicine including Sipjeondaebo-tang, and Hominis Placenta pharmacopuncture were mainly used. Collaborating with internal medicine of our hospital, essential medications for herpes zoster including antihistamine, corticosteroid, and acyclovir were administered. To assess symptoms, taking photos and numerical rating scale(NRS) were used. Results : On the 3rd day of hospitalization, erythema on the right hand disappeared. On the 4th day, discomfort arisen by zoster lesions dropped from NRS 8, which was initially evaluated, to NRS 0. Facial lesion also steadily improved. At the moment of discharge, erythema on the right side of oral angle disappeared and mild traces of vesicular lesions remained on the right hand. Conclusions : Considering her medical history, the recent recurrent herpes zoster was suspected as an adverse event of COVID-19 vaccination. Unlike general course of herpes zoster, the skin lesions and discomfort were rapidly improved owing to the collaborated treatment during the 10 days. This study may be the first literature on herpes zoster following COVID-19 vaccination in Korea.
