Perforator flaps have become increasingly popular in microsurgery nowadays and are being used widely for many cases of reconstruction after trauma and cancer ablation. And thoracodorsal perforator based free flap is one of them having the merits of carrying a large skin paddle with leaving intact innervation and function of the remaining latissimus dorsi muscle. We made a homogeneous thin flap excluding the main muscle with a long vascular pedicle and tried to decrease the donor site morbidity. But, it needs a long learning-curve and we have met marginal flap necrosis frequently. Besides, prolonged operation time for complete perforator dissection may be a tedious job to the microsurgeon. To overcome these disadvantages, we usually included very small portion of the latissimus dorsi muscle during this flap elevation around the pedicled 2-3 thoracodorsal perforators during this flap elevation. We performed 3 cases of thoracodorsal perforator based free flap at Hallym university sacred heart hospital between May and August 2005 for the soft tissue defect of the scalp and feet. The average flap size was $8{\times}14\;cm$. Although it is not a true perforator flap, we can get the reliability for the flap survival with much better blood circulation and save the time of one or two hours to dissect the perforators completely. All cutaneous flaps survived completely without any complication except one fatty female who had the very small superficial fat necrosis due to flap bulkiness. We believe the thoracodorsal perforator based free flap can be extended its versatility and reliability by including the very small portion of the muscle around the perforators.
Objectives Edema occurs in various disorders, such as heart failure, nephrotic syndrome, renal failure, liver cirrhosis, and cancer. The excessive accumulation of interstitial fluid in limb tissue will often manifest with ankle and knee swelling and lowers patient's quality of life. But the conventional treatment includes restricting dietary sodium and using diuretics. The purpose of this study is about significant improvement of a patient with edema who had suffered from dependent gait accompanied by mild pain, after treatment by herbal medicine based on SCM(Sasang constitutional medicine). Methods The pattern identification of the patient was diagnosed with a superficial disease of Taeeumin. So after the admission, Gunyuljejo-tang was used, almost two times per day during 2 weeks. Also, we applied acupuncture routinely every day and western medicine as needed. We measured the circumferences of Lt. thigh and followed up the bioelectrical impedance analysis and checked the appearance of lower limb. Results and Conclusions The therapy was effective, and the circumferences, which was 59.69cm at onset time, decreased to 52.07cm almost same to the healthy side of her thigh. There was no more edematous sign on the body, either. This case showed that management of Taeeumin's healthy energy(呼散之氣, the energy of exhalation) could be effective in treating edema.
Purpose: Malnutrition is a significant issue for pediatric patients with cancer. We sought to evaluate the effectiveness and complication rate of percutaneous endoscopic gastrostomy (PEG) placement in pediatric oncology patients. Methods: A retrospective chart review was performed on 49 pediatric oncology patients undergoing PEG placement at Johns Hopkins All Children's Hospital between 2000 and 2016. Demographic and clinical characteristics, complications, absolute neutrophil count at time of PEG placement and at time of complications, length of stay, and mortality were identified. Weight-for-age Z-scores were evaluated at time of- and six months post-PEG placement. Results: The overall mean weight-for-age Z-score improved by 0.73 (p<0.0001) from pre- (-1.11) to post- (-0.38) PEG placement. Improvement in Z-score was seen in patients who were malnourished at time of PEG placement (1.14, p<0.0001), but not in those who were not malnourished (0.32, p=0.197). Site infections were seen in 12 (24%), buried bumper syndrome in five (10%), and tube dislodgement in one (2%) patient. One patient (2%) with fever was treated for possible peritonitis. There were no cases of other major complications, including gastric perforation, gastrocolic fistula, clinically significant bleeding, or PEG-related death documented. Conclusion: Consistent with previous studies, our data suggests a relationship between site complications (superficial wound infection, buried bumper syndrome) and neutropenia. Additionally, PEG placement appears to be an effective modality for improving nutritional status in malnourished pediatric oncology patients. However, larger prospective studies with appropriate controls and adjustment for potential confounders are warranted to confirm these findings.

A 57 years old female complained of severe pain on the right temporomandibular joint (TMJ) area. Her right condyle had been partly resected under surgical operation 13 years ago due to condyle hypertrophy, thereafter she felt dull pain on TMJ area and recently the lesion became severely swelled and painful leading to cancer phobia. The present radiological views showed slightly enlarged and sclerosed condyle with increased radiopacity, but its articular sliding function was almost disable during mouth opening. The patient's TMJ lesion was carefully managed with conservative physiotherapy and pain treatment. The microsection of condyle head obtained from the previous operation was re-evaluated histologically, and it was finally diagnosed as osteochondrosis dissecans (OCD), exhibiting hyperplastic proliferation of cartilage in condyle head and marked vascular dilatation in epiphyseal zone. This abnormal cartilage tissue was distinguishable from normal cartilage tissue found in the peripheral cartilaginous cap of the same microsection. The involved cartilage cap showed thick hypertrophic chondrocyte zone with horizontal and vertical clefts accompanying diffuse hyaline degeneration. The superficial fibrous zone of cartilage cap was thickened and frequently peeled off, while lower hypertrophic zone of cartilage cap was highly cellular and proliferative. Consequently, the endochondral ossification became aberrant and resulted pre-mature apoptosis of many hypertrophic chondrocytes, followed by diffuse and mild inflammatory reaction in the underlying marrow tissue. Therefore, it was suggested that this hypertrophic condyle lesion, OCD, be differentiated depending on radiological and histological features from ordinary condyle hyperplasia, osteochondroma, and osteoarthritis, and that the pathological confirmation of OCD may provide a reliable modality for dental and medical treatment of chronic and painful TMJ lesion.

Background In immediate breast reconstruction using an extended latissimus dorsi musculocutaneous (eLDMC) flap, the volume of the flap decreases, which causes a secondary deformity of the breast shape. Since little research has investigated this decrease in muscle volume, the authors conducted an objective study to characterize the decrease in muscle volume after breast reconstruction using an eLDMC flap. Methods Research was conducted from October 2011 to November 2016. The subjects included 23 patients who underwent mastectomy due to breast cancer, received immediate reconstruction using an eLDMC flap without any adjuvant chemotherapy or radiotherapy, and received a computed tomography (CT) scan from days 7 to 10 after surgery and 6 to 8 months postoperatively. In 10 patients, an additional CT scan was conducted 18 months postoperatively. Axial CT scans were utilized to measure the volumetric change of the latissimus dorsi muscle during the follow-up period. Results In the 23 patients, an average decrease of 54.5% was observed in the latissimus dorsi muscle volume between the images obtained immediately postoperatively and the scans obtained 6 to 8 months after surgery. Ten patients showed an average additional decrease of 11.9% from 6-8 months to 18 months after surgery. Conclusions We studied changes in the volume of the latissimus dorsi muscle after surgery using an eLDMC flap performed after a mastectomy without adjuvant chemotherapy or radiotherapy. In this study, we found that immediate breast reconstruction using a latissimus dorsi muscle flap led to a decrease in muscle volume of up to 50%.
Background: We defined melanoma distribution in a large series of Turkish patients and evaluated the prognostic parameters of melanomas. Materials and Methods: A total of 1574 patients' data was retrospectively collected at 18 centers in Turkey. Demographic characteristics were questioned and noted. Prognostic parametres were evaluated based on sentinel lymph node involvement. Results: Mean age was 56.7 (4-99) years. While 844 (53.6%) cases were male, 730 (46.4%) cases were female. One thousand four hundred forty-seven (92%) cases were invasive melanoma and 127 (8%) cases were in-situ melanoma. The most common histopathological form was the superficial spreading melanoma (SSM) which was found in 549 patients (37.9%). It was followed by nodular melanoma in 379 (26.2%), acral lentiginous melanoma (ALM) in 191 (13.2%) and lentigo maligna melanoma in 132 (9.1%), respectively. On univariate analysis, lymphovascular invasion (p<0.001), tumor thickness (p<0.001), histopathological subtype (p<0.001), Clark level (p=0.001), ulceration (p<0.001), ${\geq}6/mm^2$ mitosis (p=0.005), satellite formation (p=0.001) and gender (p=0.03) were found to be associated with sentinel lymph node positivity. Regression was associated with sentinel lymph node negativity (p=0.017). According to multivariate analysis, lymphovascular invasion and tumor thickness were significant independent predictive factors of SLN positivity. Patient age, tumor localization, precursor lesions, lymphocytic infiltration and neurotropism were not related with sentinel lymph node involvement. Conclusions: In this retrospective analysis, it was found that the prevalence of SSM is at a lower rate while the prevalence of ALM is at a higher rate when compared to western countries. According to Breslow index; most of the melanoma lesions' thickness were greater than 2 mm, corresponding Clark IV. Vascular invasion and tumor thickness are the most important factors for sentinel lymph node involvement.
The proto-oncogene bcl-2 confers a survival advantage to cells by blocking programmed cell death (apoptosis). Overexpression of bcl-2 probably plays a role in tumorigenesis, and the expression of the bcl-2 protein has been investigated in many kinds of tumors. An increased expression of nitric oxide synthetase(NOS) has been observed in human colon cancer cell lines as well as in human gynecological, breast, and CNS tumors. However there have been only a few reports on the expression of bcl-2 and $NOS_2$ in oral white lesions and cancer. The aim of this study was to investigate the relationship between the expression of Bcl-2 and $NOS_2$ and several pathological parameters such as histological types and layers. We reported desregulation of bcl-2 and $NOS_2$ expression during progression from oral white lesion, lichen planus and leukoplakia to squamous cell carcinoma. The obtained results were as follows: 1. Immunohistochemical analysis with monoclonal antibodies to bcl-2 oncoprotein and $NOS_2$ in formalin-fixed paraffin-embedded tissue sections revealed that bcl-2 expression is restricted to the basal cell layer and $NOS_2$ was mild expressed only in subepithelial inflammatory cells in normal human mucosa. There wasn't specific finding of those in lichen planus and leukoplakia. 2. Bcl-2 immunoreactivity in severe epithelial dysplasia or CIS occurs throughout the epithelium, $NOS_2$ reactivity in most superficial layer were noted. 3. In well-differentiated squamous cell carcinomas, mostly bcl-2 was overexpressed. In moderated and poor squamous cell carcinomas, the expression of $NOS_2$ was increased and that of bcl-2 was decreased. 4. The immunoreactivity of bcl-2 was 12.5% of normal mucosa, 30% of leukoplakia, 44% of lichen planus and 67% of carcinoma in situ. In carcinoma, those were 43%, 50% and 67% according to differentiation, respectively. 5. The immunoreactivity of $NOS_2$ was 25% of normal mucosa, 70% of leukoplakia, 78% of lichen planus and 100% of carcinoma in situ and epithelial dysplasia. In carcinoma, those were higher in moderated(100%) and poor(83%) squamous cell carcinomas than in well differentiated type(71%). 6. The expression of bcl-2 and $NOS_2$ by Western blot was increased highly in lichen planus and leukoplakia. Therefore, the expression of bcl-2 was increased in the white and precancerous lesions and that was decreased by differentiation of carcinoma. However, $NOS_2$ immunoreactivity in carcinoma in situ was lower than those in moderated and poor squamous cell. These findings suggest that the interaction of bcl-2 and $NOS_2$ may be roled importantly in growth and development of carcinoma.
The purpose of this study is to evaluate the monitor unit obtained from various methods for the treatment of superficial cancers using electron beams. Thirty-three breast cancer patients who were treated in our institution with 6, 9, and 12 MeV electron beams, were selected for this study. For each patient, irregularly shaped treatment blocks were drawn on simulation film and constructed. Using the irregular blocks, monitor units to deliver 100 cGy to the dose maximum (dmax) were calculated from measurement and three-dimensional radiation treatment planning (3D RTP) system (PINNACLE 6.0, ADAC Laboratories, Milpitas CA) Measurements were made in solid water phantom with plane parallel (PP) chamber (Roos, OTW Germany) at 100 cm source-to surface distances. CT data was used to investigate the effect of heterogeneity. Monitor units were calculated by overriding CT values with 1 g/㎤ and in the presence of heterogeneity. The monitor unit values obtained by the above methods were compared. The dose, obtained from measurement in solid water phantom was higher than that of RTP values for irregularly shaped blocks. The maximum differences between monitor unit calculated in flat water phantom at gantry zero position were 4% for 6 MeV and 2% for 9 and 12 MeV electrons. When CT data was used at a various gantry angle the agreement between the TPS data with and without density correction was within 3% for all energies. These results indicate that there are no significant difference in terms of monitor unit when density is corrected for the treatment of breast cancer patients with electrons.

Purpose: Unplanned excision of a soft tissue sarcoma is defined as the operation performed for gross removal of a soft tissue sarcoma without regard for preoperative imaging or the necessity to removal a margin of normal tissue covering the cancer. We report our experience of treating primary soft tissue sarcoma after an unplanned excision. Materials and Methods: We retrospectively reviewed 31 patients referred to our hospital after unplanned excision at other hospitals for treatment of a STS. The clinical information was reviewed with a focus on the patient's age, gender, tumor location, tumor size, tumor depth, presumptive diagnoses at the previous surgery, refer hospital, definitive diagnosis, interval between the initial and additional surgery and local recurrence. Results: There were 19 males and 12 females with a median age of 48 years (range, 17-75 years) at the time of referral. Seventeen patients (54.8%) had tumors in their lower limb, 6 (19.4%) had tumors in their upper limb, and 8 (25.8%) had tumors in their trunk. Tumor depth could be determined for 8 patients (25.8%), with superficial and 22 deep tumors (71%). The medial interval between unplanned excision to re-excision ranged from 2 weeks to 1 year (median, 5 weeks). Local recurrence was detected in 2 patients. All patients were alive without metastasis at last follow up. Conclusion: Even in upper class general hospital, many unplanned excision had been performed, which is considered to be avoided. When the relatively huge mass located in deeper layer it requires enough preoperative imaging studies and biopsy.
To complement and develop the Orient Medical Bian Zheng treatmemt(韓方辨證施治), I have observed and analysed 68 persons who have recieved medical treatment because of the epigastric pain. Considering and analysed the Clinical Diagnosis(臨床診斷) and Clinical Bian Zheng(臨床辨證), Clinical Diagnosis(臨床診斷) and Gastroscopic Bian Zheng(微觀辨證), Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證), case history, age and sex, I have obtained the conclusion as follows. 1. The frequency of epigastric pain according to the classfication of Clinical Bian Zheng(臨床辨證) most occured in Gi Che Zheng(氣滯證), then in Huh Han Zheng(虛寒證). and least in Wi Youl Zheng. 2. There is no clear connection between the Clinical Bian Zheng(臨床辨證) and Clinical Diagnosis(臨床診斷). 3. The frequency of the epigastric pain according to Gastroscopic Bian Zheng(微觀辨證), mainly occurred in Wi youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷滯型)and then occurred in Wi Han Type(胃寒型), and least occurred in Wi Rac A Che Type(胃絡瘀滯型) 4. Having observed the relation between the Gastroscopicin Bian Zheng(微觀辨證), and Clinical Diagnosis(臨床診斷) as pathological process, I have obtained the result that Wi Youl type(胃熱型) and Wi Rac Jac Sang Type(胃絡灼傷型) mainly occurred in Erosive Gastritis and Superficial Gastritis at the early stage, and Wi Rac A Che Type(胃絡瘀滯型) occurred in the whole stage among the Wuperficial Gastritis, Atro pic Gastritis, and Erosive Gastritis, Gastric Cancer, and the Wi Han Type(胃寒型) mainly occurred in Atropic Gastritis at the later stage. 5. The relation between Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證) do not coincide. 6. Observing the relation between the Clinical Bian Zheng(臨床辨證) and case history, Gi Che Zheng(氣滯證), Huh Han Zheng(虛寒證), Wi Youl Zheng(胃熱證) were commonly seen in the early stage of the case history, and Eum Huh Zheng(陰虛證) and Houl A Zheng(血瘀證) were seen in every stage. 7. Observing the relation between the Clinical Bian Zheng(臨床辨證) and age, Gi Che Type(氣滯型) was mostly seen in the thirties and other Bian Zheng(辨證) was seen after the middle 8. Observing the relation between the Clinical Bian Zheng(臨床辨證) and sex, Gi Che Type(氣滯型) was seen at high ratio in both sexes. 9. Observing the relation between the Gastroscopic Bian Zheng(微觀辨證) and case history Wi Han Type(胃寒證), Wi Youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷型) were seen in the early stage of the case history Wi Rac A Che Type(胃絡瘀滯型) was mostly seen in the later stage. 10. There was no clear connection between the Gastroscopic Bian Zheng(微觀辨證) and age, sex. Although the examples were not sufficient, recipe regarding the partial variation state of stomach mucos together with Orient Medical Bian Zheng(韓方辨證) treatment seems to be useful in the effective treatment of Bi wi(脾胃) disease besides the epigastric pain.
