Background: Differentiated thyroid cancer is the most common endocrine malignancy with a generally good prognosis. Knowing long-term outcomes of each patient helps management planning. The study was conducted to develop and validate a clinical prognostic score for predicting disease remission in patients with differentiated thyroid cancer based on patient, tumor and treatment factors. Materials and Methods: A retrospective cohort study of 1,217 differentiated thyroid cancer patients from two tertiary-care hospitals in the Northeast of Thailand was performed. Associations between potential clinical prognostic factors and remission were tested by Cox proportional-hazards analysis in 852 patients (development cohort). The prediction score was created by summation of score points weighted from regression coefficients of independent prognostic factors. Risks of disease remission were estimated and the derived score was then validated in the remaining 365 patients (validation cohort). Results: During the median follow-up time of 58 months, 648 (76.1%) patients in the development cohort had disease remission. Five independent prognostic factors were identified with corresponding score points: duration from thyroid surgery to $^{131}I$ treatment (0.721), distant metastasis at initial diagnosis (0.801), postoperative serum thyroglobulin level (0.535), anti-thyroglobulin antibodies positivity (0.546), and adequacy of serum TSH suppression (0.293). The total risk score for each patient was calculated and three categories of remission probability were proposed: ${\leq}1.628$ points (low risk, 83% remission), 1.629-1.816 points (intermediate risk, 87% remission), and ${\geq}1.817$ points (high risk, 93% remission). The concordance (C-index) was 0.761 (95% CI 0.754-0.767). Conclusions: The clinical prognostic scoring model developed to quantify the probability of disease remission can serve as a useful tool in personalized decision making regarding treatment in differentiated thyroid cancer patients.

This case report details induction and maintenance of remission in a 34-year-old female patient with ulcerative colitis (UC) after Korean herbal medicine treatment. The patient diagnosed as UC after a series of examinations including endoscopy in a western medical hospital mainly presented bloody diarrhea and dyspepsia and symptoms were persistent even with medications. She was given individualized Korean herbal medicine prescriptions for 7 months and the symptoms were monitored during treatment and no adverse events were reported. After clinical remission, endoscopic remission was also confirmed by colonoscopy. Clinical remission was maintained for 30 months after treatment without Western medication for UC. This case report shows that Korean herbal medicine treatment may have the potential for complete remission of UC and further research is warranted.

Objective : The authors examined the treatment response and remission rates in patients with panic disorder after short-term pharmacotherapy in an effort to determine the factors that can be used to predict remission in Korean patients with panic disorder. Methods : Sixty-one patients with panic disorder were recruited for participation in this study. The psychological symptoms of the patients were measured using the HAMA, HAMD, STAIS, STAIT, ASI and API at baseline and after 3 months of pharmacotherapy. Results : Patients with panic disorder showed significantly lower scores on all psychological measures after 3 months of pharmacotherapy with paroxetine. The remission rate was 44.3%, and the response rate was 54.1%. The remitters showed significantly lower HAMD, HAMA, STAIS, STAIT, and ASI scores than the non-remitters. Linear regression analysis revealed that the baseline HAMA, HAMD, and ASI scores could be used to predict the remission rate after controlling for age, sex and agoraphobia. Conclusion : Compared with previous reports, our study showed a similar remission rate in Korean patients with panic disorder. Lower baseline levels of anxiety, depression, and anxiety sensitivity were found to be predictors of treatment remission in panic disorder.

Objective: We retrospectively analyzed the surgical outcomes of 42 patients with growth hormone (GH)-secreting pituitary adenoma to evaluate the clinical manifestations and to determine which preoperative factors that significantly influence the remission. Methods: Forty-two patients with GH-secreting pituitary adenoma underwent transsphenoidal surgery (TSS) between 1995 and 2007. The patient group included 23 women and 19 men, with a mean age of 40.2 (range 13-61) years, and a mean follow-up duration of 49.4 (range 3-178) months after the operation. For comparable radiological criteria, we classified parasellar growth into five grades according to the Knosp classification. We analyzed the surgical results of the patients according to the most recent stringent criteria for cure. Results: The overall rate of endocrinological remission in the group of 42 patients after primary TSS was 64% (26 of 42). The remission rate was 67% (8 of 12) for microadenoma and 60% (18 of 30) for macroadenoma. The remission rate was 30%(3 of 10) for the group with cavernous sinus invasion and 72% (23 of 32) for the group with intact cavernous sinus. Cavernous sinus invasion in Knosp grade III and IV was significantly correlated with the remission rate. There was a significant relationship between preoperative mean GH concentration and early postoperative outcome, with most patients in remission having a lower preoperative GH concentration. Conclusion: TSS is thought to be an effective primary treatment for GH-secreting pituitary adenomas according to the most recent criteria of cure. Because the remission rate in cases with cavernous sinus invasion is very low, early detection of the tumor before it extends into the cavernous sinus and a long-term endocrinological and radiological follow-up are necessary in order to improve the remission rate of acromegaly.

Objective : Postoperative data on Cushing's disease (CD) are equivocal in the literature. These discrepancies may be attributed to different series with different criteria for remission and variable follow-up durations. Additional data from experienced centers may address these discrepancies. In this study, we present the results obtained from 96 endoscopic transsphenoidal surgeries (ETSSs) for CD conducted in a well-experienced center. Methods : Pre- and postoperative data of 96 ETSS in 87 patients with CD were included. All cases were handled by the same neurosurgical team between 2014 and 2022. We obtained data on remission status 3-6 months postoperatively (medium-term) and during the latest follow-up (long-term). Additionally, magnetic resonance imaging (MRI) and pathology results were obtained for each case. Results : The mean follow-up duration was 39.5±3.2 months. Medium and long-term remission rates were 77% and 82%, respectively. When only first-time operations were considered, the medium- and long-term remission rates were 78% and 82%, respectively. The recurrence rate in this series was 2.5%. Patients who showed remission between 3-6 months had higher long-term remission rates than did those without initial remission. Tumors >2 cm and extended tumor invasion of the cavernous sinus (Knosp 4) were associated with lower postoperative remission rates. Conclusion : Adenoma size and the presence/absence of cavernous sinus invasion on preopera-tive MRI may predict long-term postoperative remission. A tumor size of 2 cm may be a supporting criterion for predicting remission in Knosp 4 tumors. Further studies with larger patient populations are necessary to support this finding.

Objective : The endoscopic endonasal transsphenoidal approach is a widely-used method for the surgical treatment of pituitary adenomas. We aimed to evaluate the results of endoscopic surgery by comparing preoperative classification methods and investigating their relationship with postoperative resection and remission rates and complications. Methods : We retrospectively reviewed the medical records of 236 patients (118 males) who underwent surgery for pituitary adenomas. Preoperative Knosp classification, tumor size (TS), suprasellar extension (SSE), postoperative resection and remission rates, and complications were evaluated. Results : The follow-up period was 3 months to 6 years. The patients' ages ranged between 16 and 84 years. Endocrinologically, 114 patients (48.3%) had functional adenoma (FA), and 122 patients (51.7%) had non-functional adenoma (NFA). Among the FA group, 92 (80.7%) showed remission. A statistically significant difference was found between patients with and without remission in terms of the Knosp, TS, and SSE classifications (p<0.01). Knosp, TS, and SSE classification grades were found to be correlated with the resection rates (p<0.01). Meningitis was seen in seven patients (3.0%), diabetes insipidus in 16 (6.9%; permanently in two [0.9%]), and rhinorrhea in 19 (8.1%). Thirty-six patients (15.3%) developed pituitary insufficiency and received hormone replacement therapy. Conclusion : The resection categories and remission rates of FAs were directly proportional to the adenoma sizes and Knosp grades, while the degree of suprasellar growth further complicated resection and remission rates. Adenoma sizes less than 2 cm and SSEs less than 1 cm are associated with favorable remission and resection rates.

Various immunotherapeutic modalities have been used based on the autoimmune pathogenic mechanisms of myasthenia gravis (MG). Cell-mediated immunity as well as auto-antibodies may play a role in the remission and relapse of MG. We recently experienced two patients with MG who showed spontaneous remission after inadvertent severe leukopenia. These findings suggest that the cell-mediated immune process is important in the treatment of MG, and selective suppression of leukocyte may induce remission in the patients with intractable MG.

Purpose : To report the decreasing indicence of HBV(Hepatitis B virus)-associated membranous nephropathy in children after HBV vaccination and to elucidate the clinical course and treatment strategies of IMN(Idiopathic membranous nephropathy). Methods : We retrospectively reviewed the clinico-pathological findings of HBV-MN and IMN patients who underwent a renal biopsy from 1986 to 2005. We compared the HBV-MN and the IMN groups and the remission and the non-remission groups of patients with IMN. Results : Among 24 cases of MN patients, HBV-MN comprised 6 cases(25%) and IMN 18 cases(75%). Clinical masnifestations were nephrotic syndrome(3 cases, 50%), nephritic syndrome(1 case, 16.7%), asymptomatic(2 cases, 33.4%) in the HBV-MN group, asymptomatic(10 cases, 55.5%), nephrotic syndrome(5 cases, 27.8%), and gross hematuria(3 cases, 16.7%) in the IMN groups. From 1996 to 2000, there were 2 cases(28%) of HBV-MN and 5 cases(72%) of IMN. After 2001 all 10 cases were IMN. In the HBV-MN group, 4 cases(66.7%) received interferon and 1 cases received methylprednisolone pulse therapy. In the IMN group, 16 cases(88.9%) received methylprednisolone, 8 cases(44.4%) were in complete remission, 2 cases(11.1%) were in partial remission, 2 cases(11.1%) were in chronic renal failure, and 5 cases(27.8%) were lost to follow-up with sustained proteinuria, 1 case(5.6%) continued to have frequent relapse of nephrotic syndrome without renal insufficiency. In the comparison between remission and non-remission groups, nephrotic range proteinuria and hypertension were more significantly common in the non-remission group(P<0.05). Conclusion : With HBV vaccination, HBV-MN has decreased markedly. IMN is a rare glomerular disease in children. Because the prognosis for patients with nephrotic range proteinuria is poor this group needs more aggressive treatment.

Purpose: The use of a 12-week steroid regimen (long-term therapy, LT) for the first episode of idiopathic nephrotic syndrome (NS) reportedly induces a more sustained remission and lower relapse rate than previous regimens, including an 8-week steroid regimen (short-term therapy, ST). Here, we assessed the potential for selective application of 2 steroid regimens (LT vs. ST) based on the days to remission (early responders [ER] vs. late responders [LR]) for the first idiopathic NS episode in children. Methods: Patients were divided into 4 subgroups (ST+ER, ST+LR, LT+ER, and LT+LR) according to the initial steroid regimen used and rapidity of response; the baseline characteristics, relapse rates, and cumulative percentage of children with sustained remission were then compared among the 4 subgroups. Results: Fifty-four children received ST, and the remaining 45 children received LT. As observed in previous studies, children receiving LT showed significantly lower relapse rates during the first year after the first NS episode than those receiving ST. The ST+ER group showed significantly lower relapse rates during the first one year and two years after the first NS episode than the the ST+LR group, whereas there were no significant differences of the relapse rates and duration to the first relapse between the ST+ER and LT+ER groups. Conclusion: We suggest that the initial steroid regimen in idiopathic NS patients can be shortened according to the duration to remission i.e., LT in patients achieving remission after the first week of steroid therapy, and ST in those achieving remission within the first week of steroid therapy.
