RESUMEN
Objective@#To assess the safety and effectiveness of high-density light-emitting diode (LED) irradiation therapy in patients with hand osteoarthritis (OA) and compare the pre- and post-intervention symptoms. @*Methods@#Twenty-three patients with hand OA underwent eight sessions of high-density LED irradiation therapy directed at the five most painful areas in the finger joints. Each session lasted for 18 minutes; and the sessions were conducted twice a week, for 4 weeks. We evaluated the degree of pain using the visual analogue scale, ring size, and passive range of motion (flexion+extension) for two most painful joints from the baseline to post-therapy (weeks 4 and 6). @*Results@#High-density LED irradiation therapy significantly reduced the pain posttreatment compared with that observed at the baseline (p0.05). No adverse events were observed. @*Conclusion@#We examined the safety and effectiveness of high-density LED irradiation therapy in reducing pain and hand swelling and improving joint mobility in patients with hand OA. These results suggest that high-density LED irradiation therapy has the potential to be an important strategy for managing hand OA.
RESUMEN
Background@#Time-domain parameters are less reliable in children due to increased arterial and chest wall compliance. We assessed the ability of indices derived from frequency analysis of photoplethysmography (PPG) and arterial blood pressure (ABP) waveforms to predict the hemodynamic state in children undergoing congenital heart surgery. @*Methods@#We analyzed waveforms after cardiopulmonary bypass period in 76 children who underwent total repair of congenital heart disease. Amplitude density of baseline and amplitude modulation in PPG and ABP by respiratory frequency were obtained using fast Fourier transform analysis and normalized by cardiac pulse height (representing respiratory modulations in venous blood [PPG-DC%] and in amplitude [PPG-AC%] at respiratory frequency). The ratio of amplitude density of PPG at the cardiac frequency (CF) to ABP-CF was used to assess vascular compliance. We assessed volume replacement (ml/kg) and vasoactive inotropic score (VIS). @*Results@#Children requiring volume replacement > 10 ml/kg (15.8%) showed higher PPG-DC% than those not requiring it (median: 52.4%, 95% CI [24.8, 295.1] vs. 36.7% [10.7, 125.7], P = 0.017). In addition, children with a VIS > 7 (22.4%) showed higher PPG-CF/ABP-CF (3.6 [0.91, 10.8] vs. 1.2 [0.27, 5.5], P = 0.008). On receiver operating characteristic curve analysis, PPG-DC% predicted a higher fluid requirement (area under the curve: 0.71, 95% CI [0.604, 0.816], P = 0.009), while PPG-CF/ABP-CF predicted a higher VIS (0.714, [0.599, 0.812], P = 0.004). @*Conclusions@#Frequency domain analysis of PPG and ABP may assess hemodynamic status requiring fluid or vasoactive inotropic therapy after congenital heart surgery.
RESUMEN
Purpose@#To report our experience of fertility preservation (FP) in female cancer patients. @*Materials and Methods@#We retrospectively analyzed the medical records of female who underwent elective oocyte or embryo cryopreservation before cancer treatment between January 2015 and December 2020 at Asan Medical Center. We analyzed the type of cancer, the rate of reuse of cryopreserved oocytes or embryos, and fertility outcomes such as the resumption of menstruation or pregnancy. @*Results@#A total of 174 patients underwent 182 oocyte retrieval cycles after controlled ovarian stimulation for oocyte or embryo cryopreservation. The median age of patients was 33.0 (range 19–46) years, and the patients were most unmarried female (65.52%). The majority of patients were diagnosed with breast cancer (78.16%), and the remaining were diagnosed with gastrointestinal (6.33%) and hematologic malignancies (5.75%). The maturation rate of oocyte cryopreservation was 83.33%, and the fertilization rate of embryo cryopreservation was 72.07%. Of the 57 patients currently not undergoing cancer treatment, 34 resumed menstruating and 19 (33.33%, 19/57) returned to attempt a pregnancy. Among them, five patients succeeded in natural pregnancy.Eleven patients received frozen-thawed embryo transfer, and four patients succeeded in becoming pregnant (36.36%, 4/11). Only 6.3% of patients returned to use their gametes, and 93.7% of gametes are still in storage. @*Conclusion@#FP in cancer patients should be considered before cancer treatment. Through continuous research on oncofertility, it is necessary to consider how to increase the return rate and provide appropriate information to cancer patients of reproductive age.
RESUMEN
Acute-on-chronic liver failure (ACLF) is a life-threatening disease that requires urgent liver transplantation (LT). Accurate identification of high-risk patients is essential for predicting post-LT survival. The chronic liver failure consortium ACLF score is a widely accepted risk-stratification score that includes total white blood cell (WBC) counts as a component. This study aimed to evaluate the predictive value of total and differential WBC counts for short-term mortality following LT in patients with ACLF. Methods: A total of 685 patients with ACLF who underwent LT between January 2008 and February 2019 were analyzed. Total and differential WBC counts were examined as a function of the model for end-stage liver disease for sodium (MELD-Na) score. The association between total and differential WBC counts and 90-day post-LT mortality was assessed using multivariable Cox proportional hazards regression analysis. Results: The total WBC counts and neutrophil ratio were higher in patients with ACLF than in those without ACLF. The neutrophil ratio was significantly associated with 90-day post-LT mortality after adjustment (hazard ratio [HR], 1.04; P = 0.001), whereas total WBC counts were not significantly associated with 90-day post-LT mortality in either univariate or multivariate Cox analyses. The neutrophil ratio demonstrated a relatively linear trend with an increasing MELD-Na score and HR for 90-day post-LT mortality, whereas the total WBC counts exhibited a plateaued pattern. Conclusions: Neutrophilia, rather than total WBC counts, is a better prognostic indicator for short-term post-LT mortality in patients with ACLF.
RESUMEN
Objective@#To evaluate the efficacy of light-emitting diode (LED) and their dual-wavelengths as a treatment strategy for osteoarthritis. @*Methods@#We induced osteoarthritis in male Sprague-Dawley rats by intra-articular injection of sodium iodoacetate into the right rear knee joint. The animals with lesions were divided into an untreated group and an LED-treated group (n=7 each). In the LED-treated group, the lesioned knee was irradiated with lasers (850 and 940 nm) and dose (3.15 J/cm2) for 20 minutes per session, twice a week for 4 weeks. Knee joint tissues were stained and scanned using an in vivo micro-computed tomography (CT) scanner. Serum interleukin (IL)-6 and IL-18 levels were determined using enzyme-linked immuno-sorbent assay. Several functional tests (lines crossed, rotational movement, rearing, and latency to remain rotating rod) were performed 24 hours before LED treatment and at 7, 14, 21, and 28 days after treatment. @*Results@#LED-treated rats showed improved locomotor function and suppressed matrix-degrading cytokines. Micro-CT images indicated that LED therapy had a preserving effect on cartilage and cortical bone. @*Conclusion@#LED treatment using wavelengths of 850 and 940 nm resulted in significant functional, anatomical, and histologic improvements without adverse events in a rat model. Further research is required to determine the optimal wavelength, duration, and combination method, which will maximize treatment effectiveness.
RESUMEN
Background@#Oral frailty has garnered considerable interest following its identification as a risk factor for physical frailty. The Koreanoral frailty diagnosis criteria have emphasized the need for extensive research on oral frailty diagnostic items and interventions.Our study performed an in-depth analysis of the tongue-palate pressure patterns in healthy community-dwelling older adults. @*Methods@#Of the 217 older adults aged ≥60 years who visited a senior center in Wonju, 205 participants who completed tongue pressure measurement were included in the final analysis. Pressure changes over time were recorded by instructing the participants to press their tongue against the hard palate with for 7 seconds per cycle. The participants were divided into the normal and abnormal tongue pressure (NTP and ATP, respectively) groups based on whether they achieved the target tongue pressure at least once; tongue pressure patterns were compared between the groups. Furthermore, the average time taken to achieve the standard tongue pressure value was calculated for the participants in the NTP group and used to evaluate the decrease in tongue pressure in the ATP group. @*Results@#Among the 205 participants, 40.5% had ATP. The tongue pressure graph revealed a gentle and consistent incline that wasmaintained even after achieving standard tongue pressure in the NTP group. The graph was more extreme in the ATP group, and the changes in the pressure type varied across individuals; the tongue pressure was only 48.4%, 40.7%, 31.9%, and 22.6% of the NTP in the participants in their 60s, 70s, 80s, and ≥90s, respectively (p＜0.05). @*Conclusion@#Tongue pressure weakness was observed in 40.5% of the healthy community-dwelling older adults. Furthermore,ATP graphs were observed in the patients with tongue pressure weakness. Thus, activities improving the oral function in community-dwelling older adults and systematic oral rehabilitation programs should be devised to promote normal swallowing.
RESUMEN
Background@#To assess the clinical efficacy of intravenous immunoglobulin G (IVIG) administration combined with low-dose aspirin in women with unexplained recurrent pregnancy loss (RPL). @*Methods@#We retrospectively analyzed the medical records of patients who had been diagnosed with unexplained RPL and treated with IVIG and low-dose aspirin between January 2000 and March 2020 at Asan Medical Center. We analyzed pregnancy outcomes and their association with the percentage of natural killer (NK) cells. @*Results@#The study analyzed a total of 93 patients and 113 natural and assisted reproductive technology pregnancy cycles. The live birth rate per cycle was 73.5% (83/113), and the term delivery rate was 86.7% (72/83). The live birth rate was high regardless of the type of RPL, method of pregnancy, timing of IVIG treatment, and presence or absence of autoantibodies.In addition, the live birth rate was significantly higher in patients who received IVIG more than once, compared with patients who received IVIG only once (77.8% vs. 42.9%, P = 0.006). There was no significant association between the NK cell counts and live birth rate (65.5% in the group with NK cell < 12%, and 69.7% in that with NK cell ≥ 12%, P = 0.725). Among all patients, 87.6% had no complications, and there were no congenital malformation among newborn babies. @*Conclusion@#IVIG combined with low-dose aspirin treatment showed favorable pregnancy outcomes regardless of the patient’s NK cell counts (%).
RESUMEN
Objective@#To evaluate the efficacy of vaginal hysterectomy combined with anterior and posterior colporrhaphy (VH APR) for the management of pelvic organ prolapse (POP). @*Methods@#A total of 610 patients with POP who underwent VH APR from January 2010 to June 2019 at Asan Medical Center were included in this study. We analyzed the patient characteristics and surgical outcomes. In addition, we compared the POP quantification system (POP-Q) pre- and postoperatively at 2 weeks, 3 months, and 1 year, and analyzed the risk factors for recurrence. @*Results@#The mean age of the patients was 65.5±7.6 years. The most common preoperative POP-Q stage was stage 2 (60.8%), followed by stage 3 (35.9%). Complications were identified during surgery in 1.6% of the patients. The most common postoperative complication (6.4%) was voiding difficulty. All POP-Q scores significantly decreased at 1 year after surgery (P<0.0001). The recurrence rate was 9.6%, and most recurrences (77.5%) occurred in the anterior compartment. An advanced stage of preoperative POP was a risk factor for recurrence (stage 3 or 4 vs. stage 1 or 2; odds ratio [OR], 5.337, 95% confidence interval [CI], 2.58-11.036, P<0.0001). Only two patients underwent surgical correction for POP recurrence, and most of the remaining patients did not undergo further treatment for prolapse. @*Conclusion@#VH APR is a safe and effective surgical procedure for POP, with a low recurrence rate. In addition, advanced preoperative stage was the only risk factor for recurrent POP.
RESUMEN
Background/Aims@#The long-term course of Crohn’s disease (CD) has never been evaluated in non-Caucasian population-based cohorts. The aim of the present study was to evaluate the longterm prognosis of Korean CD patients in the well-defined population-based Songpa-Kangdong inflammatory bowel disease cohort. @*Methods@#Outcomes of disease and their predictors were evaluated for 418 patients diagnosed with CD between 1986 and 2015. @*Results@#During a median of 123 months, systemic corticosteroids, thiopurines, and anti-tumor necrosis factor (TNF) agents were administered to 58.6%, 81.3%, and 37.1% of patients, respectively. Over time, the cumulative probability of starting corticosteroids significantly decreased (p=0.001), whereas that of starting thiopurines and anti-TNFs significantly increased (both p<0.001). The cumulative probability of behavioral progression was 54.5% at 20 years, and it significantly decreased during the anti-TNF era. Intestinal resection was required for 113 patients (27.0%). The cumulative probabilities of intestinal resection at 1, 5, 10, 20, and 25 years after CD diagnosis were 12.7%, 16.5%, 23.8%, 45.1%, and 51.2%, respectively. Multivariable Cox regression analysis identified stricturing behavior at diagnosis (adjusted hazard ratio [aHR], 2.70; 95% confidence interval [CI], 1.55 to 4.71), penetrating behavior at diagnosis (aHR, 11.15; 95% CI, 6.91 to 17.97), and diagnosis of CD during the anti-TNF era (aHR, 0.51; 95% CI, 0.35 to 0.76) as independently associated with intestinal resection. The standardized mortality ratio among CD patients was 1.36 (95% CI, 0.59 to 2.68). @*Conclusions@#The long-term prognosis of Korean patients with CD is at least as good as that of Western CD patients, as indicated by the low intestinal resection rate. Moreover, behavioral progression and intestinal resection rates have decreased over the past 3 decades.
RESUMEN
The coronavirus disease 2019 (COVID-19) pandemic has impacted the medical, social, and reproductive health of millions of people since its outbreak. The causative virus transmits, reproduces, and manifests through the respiratory tract. COVID-19 can invade any system of the body, including the cardiovascular and endocrine systems, through a secondary immune response. In particular, because the fatality rate is high in those over the age of 50 years, special attention is required during the medical care of this population. However, considering the benefit of therapy and the risk of COVID-19, high-quality evidence regarding individualized management in relation to hormone therapy is still insufficient in the field of gynecology. Furthermore, this review aims to serve as a reference for clinical application by analyzing and summarizing the results of studies reported to date regarding female hormone therapy in the context of the COVID-19 pandemic.
RESUMEN
Objective@#Ultrasonographic differential diagnosis of ovarian tumors is important for appropriate management. We conducted study to compare the performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model with a subjective assessment (SA) in differentiating between benign and malignant adnexal masses in Korean women. @*Methods@#A total of 353 patients who underwent adnexal surgery with abnormal pelvic ultrasonographic findings from August 2016 to August 2017 were included in study. The presumptive diagnosis of adnexal malignancy was determined by both SA and the ADNEX model to be >10% calculated risk of malignancy. The area under the curve (AUC) comparison between the SA and ADNEX models was performed using DeLong’s method. @*Results@#340 patients with benign tumors and 13 with malignant adnexal tumors among 292 (82.72%) premenopausal and 61 (17.28%) postmenopausal women were included. The AUCs of SA and the ADNEX model for discrimination between benign and malignant tumors were 0.79 and 0.92, respectively (P=0.10). The sensitivity and specificity of SA and the ADNEX model were 83.5% and 97.0%, and 90.0% and 82.0%, respectively. Comparison of the ADNEX model regarding menopausal status revealed that the predictability was not different. The AUCs of SA and the ADNEX model in premenopausal women were 0.74 and 0.89, respectively (P=0.12). The AUCs of SA and the ADNEX model in postmenopausal women were 0.86 and 0.94, respectively (P=0.60). @*Conclusion@#The ADNEX model offers excellent discrimination between benign and malignant ovarian tumors with similar sensitivity and specificity to SA in both premenopausal and postmenopausal Korean women.
RESUMEN
Purpose@#In young patients with varicocele, preservation of the internal spermatic artery may be advantageous for catch-up growth, but it may also increase the likelihood of treatment failure. Intraoperative venography reduces the likelihood that unsealed veins will remain after varicocelectomy. We analyzed the characteristics of remnant veins visualized through intraoperative venography to investigate the cause of surgical failure in artery-sparing varicocelectomy (ASV). @*Materials and Methods@#We retrospectively analyzed clinical characteristics and outcomes of patients aged 18 years or younger who underwent varicocelectomy with intraoperative venography from January 2005 to December 2017. During varicocelectomy, intraoperative venography was performed to distinguish veins from other structures. Any unsealed veins that were discovered were ligated and classified using the Bähren system. @*Results@#One hundred and sixty-two patients underwent intraoperative venography: 153 cases (94.4%) were for primary varicocelectomy, and 9 cases (5.6%) were for repeat varicocelectomy. Open varicocelectomy was performed in 105 cases (64.8%), and laparoscopic varicocelectomy was performed in 57 cases (35.2%). Venography revealed remnant veins after the first ligation in 51 cases (31.2%), 46 (90.2%) and 5 (9.8%) of which were Bähren types 3 and 4, respectively. Five patients (3.1%) experienced varicocele recurrence, classified as persistence in 1 patient (0.6%) and relapse in 4 patients (2.5%). @*Conclusion@#Remnant collateral veins of the internal spermatic vein (ISV) (Bähren type 3) are the most common cause of failure in ASV. In a few patients, an external spermatic vein merges with the ISV at a higher level (Bähren type 4) and is unidentifiable without venography.
RESUMEN
Diagnosis of Kawasaki disease (KD) is occasionally delayed because it is solely based on clinical symptoms. Previous studies have attempted to identify diagnostic biomarkers for KD. Recently, patients with KD were reported to have elevated serum ferritin levels. We investigated the usefulness of the serum ferritin level as a diagnostic biomarker for distinguishing KD from other acute febrile illnesses. Blood samples were obtained from pediatric patients with KD (N = 77) and those with other acute febrile illnesses (N = 32) between December 2007 and June 2011 for measuring various laboratory parameters, including serum ferritin levels. In patients with KD, laboratory tests were performed at diagnosis and repeated at 2, 14, and 56 days after intravenous immunoglobulin treatment. At the time of diagnosis, serum ferritin levels in patients with KD (188.8 µg/L) were significantly higher than those in patients with other acute febrile illnesses (106.8 µg/L, P = 0.003). The serum ferritin cut-off value of 120.8 µg/L effectively distinguished patients with KD from those with other acute febrile illnesses, with a sensitivity and specificity of 74.5% and 83.3%, respectively. Serum ferritin may be a useful biomarker to distinguish KD from other acute febrile illnesses.
RESUMEN
Objectives@#：This study was aimed to investigate the changes in metabolic syndrome (MetS) status and long-term impact of its components over a 10-year period in severe mental illness (SMI) patients in a national mental hospital. @*Methods@#：A total of 93 patients (schizophrenia=88, bipolar disorder=5) who met the diagnosis of Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) and participated in the MetS study in 2011 were included. MetS was defined by revised National Cholesterol Education Program-Adult Treatment Panel III (revised NCEP-ATP-III) guidelines. @*Results@#：The prevalence of MetS was significantly increased from 40.9% in 2011 to 60.2% in 2020. There were significant differences in admission status and hospitalization months, compared to the groups with and without MetS. Upon reviewing the changes over a decade, systolic blood pressure (SBP) was a significant factor in the group without MetS. In the group with MetS, SBP, waist circumference, and BMI (body mass index) were significant factors. Multiple logistic regression analysis revealed that hospitalization during follow-up periods [odds ratio (OR)=0.969, 95% confidence interval (CI): 0.948-0.991] and BMI (OR=1.426, 95% CI: 1.196-1.701) were significantly associated with MetS in subjects. @*Conclusion@#：The prevalence of MetS in patients with SMI significantly increased over time. The admission status and hospitalization were also confirmed to be the significant values of MetS.
RESUMEN
Background/Aims@#We aimed to evaluate the clinical characteristics and long-term prognosis of elderly-onset ulcerative colitis (EOUC) in Korean patients over a 30-year period using a wellestablished population-based cohort in the Songpa-Kangdong district of Seoul, Korea. @*Methods@#Clinical characteristics and prognosis were compared between two groups: EOUC,defined as UC diagnosed in individuals aged ≥60 years and non-EOUC (N-EOUC), defined asUC diagnosed in individuals aged 18 to 59 years. @*Results@#We identified 99 patients with EOUC (10.3%) and 866 patients with N-EOUC (89.7%) between 1986 and 2015. During the median follow-up of 104.5 months, the overall exposure tomedications was comparable between patients with EOUC and N-EOUC (p=0.091 for corticosteroids, p=0.794 for thiopurines, and p=0.095 for anti-tumor necrosis factor agents). The cumula-tive risks of disease outcomes were also comparable between patients with EOUC and N-EOUC (22.4% vs 30.4% for proximal disease extension [p=0.351], 11.9% vs 18.1% for hospitalization [p=0.240], and 2.3% vs 1.8% for colectomy [p=0.977]) at 10 years after diagnosis. Multivariate Cox regression analysis revealed that corticosteroid use at diagnosis was an independent predic-tor of proximal disease extension (hazard ratio [HR], 6.216; 95% confidence interval [CI], 1.314 to 28.826) and hospitalization (HR, 11.241; 95% CI, 3.027 to 41.742) in patients with EOUC. @*Conclusions@#In this population-based study from Korea, the pattern of medication use seemed comparable between the EOUC and N-EOUC groups. Moreover, patients with EOUC and those with N-EOUC have a similar disease course in terms of proximal disease extension, hospitaliza-tion, and colectomy.

RESUMEN
Objective@#We compared the efficacy and postoperative complications of tension-free vaginal tape (TVT)-abbrevo® (TVT-A) and TVT-obturator® (TVT-O) surgeries for the treatment of stress urinary incontinence (SUI). @*Methods@#We retrospectively analyzed the medical records of 143 female patients with SUI who underwent TVT-A or TVT-O surgery between January 2010 and December 2019 at the Asan Medical Center in Seoul. We evaluated intra- and postoperative complications such as bladder injury, groin pain, urinary retention, and mesh exposure. We also checked the success rate at 6 months after surgery. @*Results@#There were no complications, including fever, hematuria, hematoma of the vulva, or bladder injury, immediately after surgery in either group. Postoperative complications 2 weeks post-surgery were groin pain (11.3%), urinary retention (4.9%), and mesh exposure (0.7%). Groin pain was not significantly different between the two groups at 2 weeks, 3 months, and 6 months after surgery (TVT-O vs. TVT-A after 2 weeks: 12.5% vs. 10.3%, P=0.791; 3 months: 0.0% vs. 1.4%, P=0.999; and 6 months: 0.0% vs. 0.0%, P=0.999). Over 90% of the patients reported cure or improved symptoms in both groups. In the univariate logistic analysis, the type of TVT (TVT-O or TVT-A) was not associated with the success rate (odds ratio, 3.21; 95% confidence interval, 0.59-17.40; P=0.175). @*Conclusion@#TVT-A surgery is comparable with TVT-O in terms of high success rate and low frequency of complications, including bladder injury and groin pain.
RESUMEN
Amyloidosis is a disease in which abnormal proteins called amyloid accumulates in various tissues. In the head and neck area, the larynx is the most common site with the rare involvement of the tongue, causing symptoms of macroglossia. Most of amyloid light-chain (AL) amyloidosis are systemic amyloidosis accompanied with multiple myeloma (MM), where the involvement of tongue can be often observed. We report a case of AL amyloidosis with MM, initially with symptoms of dysarthria and dysphagia without macroglossia, but gradually over the years, macroglossia and high tongue stiffness were observed.
RESUMEN
Objectives@#Ovarian suppression using Gonadotropin releasing hormone (GnRH)-agonist in premenopausal women with breast cancer has been known to improve disease-free survival and overall survival. However, long-term effect of ovarian suppression on lipid metabolism has not been studied yet. In this retrospective cohort study, we aimed to investigate cholesterol changes during medical ovarian suppression. @*Methods@#and Materials: We reviewed medical records and blood test results of 152 women who have been diagnosed as breast cancer and started GnRH-agonist every 12 weeks therapy for more than 24 weeks in Asan Medical Center between 2018.1.1 and 2020.12.31. Patients who had previously diagnosed dyslipidemia or diabetes, or newly received lipid-lowering agents during study period were excluded from the cohort. Age at diagnosis and preoperative Body Mass Index (BMI) were investigated as baseline demographics. Generalized additive mixed model was applied to analyze the relationship between duration of GnRH-agonist and cholesterol changes. @*Results@#The age was distributed as 42.5±5.2 years old (mean±SD), and preoperative BMI was 23.0±3.6 kg/m2 (mean±SD). Duration of GnRH agonist therapy ranged from 5.6 to 37.7 months, with mean of 19.3. Total cholesterol was 171 mg/dL before starting GnRH-agonist, whereas 181 mg/dL on last check, which was significantly higher than initial value (p=0.03). Duration of GnRH-agonist did not affect total cholesterol level until 19.3 months, while significantly increased by 1.8 mg/dL for each month thereafter (p=0.011). There was no significant effect of age, preoperative BMI and GFR on total cholesterol. @*Conclusion@#While long-term use of GnRH-agonist is applied, patients should be monitored for dyslipidemia after 19 months of treatment and lipid-lowering agents may be considered especially when indicated.
