Wound pain is a common issue during wound care procedures such as dressing changes and debridement, significantly affecting patient comfort and recovery. Effective pain management is essential, not only for enhancing quality of life but also for promoting healing and minimizing complications. Factors like resting pain intensity, expected pain, and type of dressing have been identified as key predictors of severe wound pain during these procedures, helping clinicians manage pain more effectively by enabling early intervention. The Wound Pain Management Model was developed to guide healthcare professionals in managing chronic wound pain through steps like wound assessment, local treatment, and systemic management when necessary. While opioids are a common treatment, concerns over dependence and side effects have led to the exploration of alternatives. Virtual reality (VR) has emerged as a promising non-pharmacological approach, reducing pain through distraction, particularly in burn and chronic wound care. However, variability in study designs limits the current understanding of VR’s overall effectiveness. This review examines both pharmacological and non-pharmacological approaches to wound pain management, with a focus on VR. Further research with larger, more consistent studies is needed to better assess VR’s long-term benefits across different patient groups and wound types.
2.Development of Macrocyclic Ligands for Stable Radiometal Complexes.
Korean Journal of Nuclear Medicine 2005;39(4):215-223
Current interest in the regioselective N-functionalization of tetraazacycloalkanes (cyclen and cyclam) stems mainly from their complexes with radioactive metals for applications in diagnostic (64Cu, 111In, 67Ga) and therapeutic (90Y) medicine, and with paramagnetic ions for magnetic resonance imaging (Gd+3). Selective methods for the N-substitution of cyclen and cyclam is a crucial step in most syntheses of cyclen and cyclam-based radiometal complexes and bifunctional chelating agents. In addition, mixing different pendent groups to give hetero-substituted cyclen derivatives would be advantageous in many applications for fine-tuning the compound's physical properties. So far, numerous approaches for the regioselective N-substitution of tetraazacycloalkanes and more specifically cyclen and cyclam are reported. Unfortunately, none of them are general and every strategy has its own strong points and drawbacks. Herein, we categorize numerous regioselective N-alkylation methods into three strategies, such as 1) direct substitution of the macrocycle, 2) introduction of the functional groups prior to cyclization, and 3) protection/functionalization/deprotection. Our discussion is also split into the methods of mono- and tri-functionalization and di-functionalizataion based on number of substituents. At the end, we describe new trials for the new macrocycles which form more stable metal complexes with various radiometals, and briefly mention the commercially available tetraazacycloalkanes which are used for the biconjugation of biomolecules.

PURPOSE: Colonoscopy is a safe and commonly used method for the screening of colon cancer, but sometimes major complications, such as, colonic perforation or hemorrhage occur during the procedure. The aim of this study was to compare the surgical outcomes of laparoscopic and open surgery for colon perforation after colonoscopy. METHODS: A retrospective review of patient records was performed on 25 patients with iatrogenic colon perforation during colonoscopy during the 7-year period from January 2005 to June 2012. Demographic data, operative procedures, operation times, postoperative complications, hospital course, and morbidities in the laparoscopic surgery group (LG) and open surgery group (OG) were compared. RESULTS: Seventeen of the 25 patients underwent laparoscopic surgery (68%) and 8 patients open surgery (32%). The most common surgical methods were primary repair in the LG, and Hartmann's operation in the OG. Average time to first flatus was 2.9 days in the LG and 4.5 days in the OG, and average times to first meals were 4.5 days and 5 days, respectively. Mean hospital stays were 10.8 days in the LG and 17 days in the OG. After surgery, complications occurred in two patients in the LG, but no complication occurred in the OG. CONCLUSION: Laparoscopic repair for iatrogenic colonic perforation during colonoscopy seems to be useful and safe surgical method in early period after perforation. However, open surgery is also needed for the delayed cases after perforation.

Interleukin-17 (IL-17) is secreted by a class of helper T cells called Th17 cells, which stimulates keratinocytes to secrete proinflammatory mediator and to recruit other inflammatory cells in psoriatic skins. IL-17A inhibitor was approved for the management of psoriatic arthritis by FDA. It is the one of the biologics approved as first-line therapy for the management of psoriasis. But several studies show some side effects of IL-17A inhibitor such as upper respiratory infection and fungal infection like Candida albicans. Herein we report a widespread dermatophytosis during IL-17A inhibitor treatment. A 66-year-old male patient, with tinea unguium and chronic plaque psoriasis for several decades, presented with multiple erythematous scaly macules and patches for 2 weeks. He medicated IL-17A inhibitor for treating psoriasis total 3 times and last injection was 1 week ago. Dermatological examination revealed the involvement of 20% body surface area in the form of erythematous scaly macules and patches. KOH mount revealed the presence of numerous hyphae. The patient was started on oral terbinafine, topical isoconazole and efinaconazole. His skin lesions were improved after 1 month of anti-fungal therapy. IL-17 plays an important role in mucocutaneous microbial defense. So, fungal infection should be checked in using IL-17A inhibitor patients periodically.

Background:
Recognizing the seriousness of the misuse and abuse of medical narcotics, the South Korean government introduced the world's first narcotic management system, the Narcotics Information Management System (NIMS). This study aimed to explore the recent one-year opioid prescribing patterns in South Korea using the NIMS database.
Methods:
This study analyzed opioid prescription records in South Korea for the year 2022, utilizing the dispensing/ administration dataset provided by NIMS. Public data from the Korean Statistical Information Service were also utilized to explore prescription trends over the past four years. The examination covered 16 different opioid analgesics, assessed by the total number of units prescribed based on routes of administration, type of institutions, and patients’ sex and age group. Additionally, the disposal rate for each ingredient was computed.
Results:
In total, 206,941 records of 87,792,968 opioid analgesic units were analyzed. Recently, the overall quantity of prescribed opioid analgesic units has remained relatively stable. The most prescribed ingredient was oral oxycodone, followed by tapentadol and sublingual fentanyl. Tertiary hospitals had the highest number of dispensed units (49.4%), followed by community pharmacies (40.2%). The highest number of prescribed units was attributed to male patients in their 60s. The disposal rates of the oral and transdermal formulations were less than 0.1%.
Conclusions
Opioid prescription in South Korea features a high proportion of oral formulations, tertiary hospital administration, pharmacy dispensing, and elderly patients. Sustained education and surveillance of patients and healthcare providers is required.

PURPOSE: Multidrug resistance (MDR) of the cancer cells related to mdr1 gene expression can be effectively treated by selective short hairpin RNA for mdr1 gene (shMDR). Sodium/iodide symporter (NIS) gene is well known to have both reporter and therapeutic gene characteristics. We have co-transfected both shMDR and NIS gene into colon cancer cells (HCT15 cell) expressing MDR and Tc-99m sestamibi and I-125 uptake were measured. In addition, cytotoxic effects of doxorubicin and I-131 therapy were also assessed after transfection. MATERIAL AND METHODS: At first, shMDR was transfected with liposome reagent into human embryonic kidney cells (HEK293) and HCT cells. shMDR transfection was confirmed by RT-PCR and western blot analysis. Adenovirus expressing NIS (Ad-NIS) gene and shMDR (Ad-shMDR) were co-transfected with Ad-NIS into HCT15 cells. Forty-eight hours after infection, inhibition of P-gycoprotein (Pgp) function by shMDR was analyzed by a change of Tc-99m sestamibi uptake and doxorubicin cytotoxicity, and functional activity of induced NIS gene expression was assessed with I-125 uptake assay. RESULTS: In HEK293 cells transfected with shMDR, mdr1 mRNA and Pgp protein expressions were down regulated. HCT15 cells infected with 20 MOI of Ad-NIS was higher NIS protein expression than control cells. After transfection of 300 MOI of Ad-shMDR either with or without 10 MOI of Ad-NIS, uptake of Tc-99m sestamibi increased up to 1.5-fold than control cells. HCT15 cells infected with 10 MOI of Ad-NIS showed approximately 25-fold higher I-125 uptake than control cells. Cotransfection of Ad-shMDR and Ad-NIS resulted in enhanced cytotoxic by doxorubicin in HCT15 cells. I-131 treatment on HCT15 cells infected with 20 MOI of Ad-NIS revealed increased cytotoxic effect. CONCLUSION: Suppression of mdr1 gene expression, retention of Tc-99m sestamibi, enhanced doxorubicin cytotoxicity and increases in I-125 uptake were achieved in MDR expressing cancer cell by co-transfection of shMDR and NIS gene. Dual therapy with doxorubicin and radioiodine after cotransfection shMDR and NIS gene can be used to overcome MDR.

PURPOSE: Adenosine myocardial perfusion SPECT has proven to be useful in the detection of coronary artery disease, in the follow up the success of various therapeutic regimens and in assessing the prognosis of coronary artery disease. The purpose of this study is to define the reproducibility of myocardial perfusion SPECT using adenosine stress testing between two consecutive Tc-99m sestaMIBI (MIBI) SPECT studies in the same subjects. METHODS: Thirty patients suspected of coronary artery disease in stable condition underwent sequential Tc-99m MIBI SPECT studies using intravenous adenosine. Gamma camera, acquisition and processing protocols used for the two tests were identical and no invasive procedures were performed between two tests. Mean interval between two tests were 4.1 days (range: 2-11 days). The left ventricular wall was divided into 18 segments and the degree of myocardial tracer uptake was graded with four-point scoring system by visual analysis. Images were interpretated by two independent nuclear medicine physicians and consensus was taken for final decision, if segmental score was not agreeable. RESULTS: Hemodynamic responses to adenosine were not different between two consecutive studies. There were no serious side effects to stop infusion of adenosine and side effects profile was not different. When myocardial uptake was divided into normal and abnormal uptake, 481 of 540 segments were concordant (agreement rate 89%, Kappa index 0.74). With four-grade scoring system, exact agreement was 81.3% (439 of 540 segments, tau b=0.73). One and two-grade differences were observed in 97 segments (18%) and 4 segments (0.7%) respectively, but three-grade difference was not observed in any segment. Extent and severity scores were not different between two studies. The extent and severity scores of the perfusion defect revealed excellent positive correlation between two test (r value for percentage extent and severity score is 0.982 and 0.965, p< 0.001) CONCLUSION: Hemodynamic responses and side effects profile were not different between two consecutive adenosine stress tests in the same subjects. Adenosine Tc-99m sestaMIBI SPECT is highly reproducible, and could be used to assess temporal changes in myocardial perfusion in individual patients.

PURPOSE: We have evaluated characteristics of adrenal masses incidentally observed in nonenhanced F-18 FDG PET/CT of the oncologic patients and the diagnostic ability of F-18 FDG PET/CT to differentiate malignant from benign adrenal masses. MATERIALS AND METHODS: Between Mar 2005 and Aug 2008, 75 oncologic patients (46 men, 29 women; mean age, 60.8+/-10.2 years; range, 35-87 years) with 89 adrenal masses incidentally found in PET/CT were enrolled in this study. For quantitative analysis, size (cm), Hounsfield unit (HU), maximum standardized uptake value (SUVmax), SUVratio of all 89 adrenal masses were measured. SUVmax of the adrenal mass divided by SUVliver, which is SUVmax of the segment 8, was defined as SUVratio. The final diagnosis of adrenal masses was based on pathologic confirmation, radiologic evaluation (HU<0 : benign), and clinical decision. RESULTS: Size, HU, SUVmax, and SUVratio were all significantly different between benign and malignant adrenal masses.(P < 0.05) And, SUVratio was the most accurate parameter. A cut-off value of 1.0 for SUVratio provided 90.9% sensitivity and 75.6% specificity. In small adrenal masses (1.5 cm or less), only SUVratio had statistically significant difference between benign and malignant adrenal masses. Similarly a cut-off value of 1.0 for SUVratio provided 80.0% sensitivity and 86.4% specificity. CONCLUSION: F-18 FDG PET/CT can offer more accurate information with quantitative analysis in differentiating malignant from benign adrenal masses incidentally observed in oncologic patients, compared to nonenhanced CT.

PURPOSE: To investigate the feasibility of Tl-201 SPECT with intracoronary injection (IC-I) in the detection of viable myocardium, we have performed SPECT imaging after direct intracoronary injection of Tl-201 and images were compared with those of stress-reinjection (Re-I) SPECT. METHODS: Fourteen coronary artery disease patients (male 11, mean age 54 years) who had myocardial infarction or demonstrated left ventricular wall motion abnormality on echocardiography were enrolled. Three mCi of Tl-201 was injected into both coronary arteries during angiography and images were acquired between 6- and 24-hour after injection. Reinjection imaging with 1 mCi of Tl-201 was performed at 4-hour after adenosine stress imaging with 3 mCi of Tl-201. Images were interpreted according to 4-grade visual scoring system (grade 0-3). Segments with mild to moderated uptake (< or=grade 1), and upgraded more than one score with reinjection, and were defined as viable myocardium. RESULTS: Image quality was poor in two cases with IC-I. Numbers of non-viable segments were 60 (23.8%) with IC-I, and 38 (15.1%) with Re-I, respectively. Overall agreement for perfusion grade per myocardial segment in each IC-I and Re-I was 76.5%. Overall agreement for viable segment between IC-I and Re-I was 90.5%. Only one out of 38 segments interpreted as non-viable with Re-I were interpretated as viable with IC-I. And 23 out of 214 segments interpreted as viable with Re-I were interpreted as non-viable with IC-I. CONCLUSION: Intracoronary Tl-201 SPECT seemed to be not advantageous over stress-rest reinjection imaging in the assessment of myocardial viability, mainly due to low count statistics at 6-hour or 24-hour delayed time points. The feasibility of intracoronary Tl-201 SPECT is considered to be limited.
