Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.

The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.

The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2022 (KMAP-BP 2022) with other recently published guidelines for treating bipolar disorder. We reviewed a total of six recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2022 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy in a same degree for mania. However, the KMAP-BP 2022 recommended MS + AAP combination therapy for psychotic mania, mixed mania and psychotic depression as treatment of choice. Aripiprazole, quetiapine and olanzapine were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Some guideline suggested olanzapine is a second-line options during maintenance treatment, related to concern about long-term tolerability. Most guidelines advocated newer AAPs (asenapine, cariprazine, long-acting injectable risperidone, and aripiprazole once monthly) as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. KMAP-BP 2022 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2022, predominantly in the treatment of psychotic mania, mixed mania and psychotic depression.

Objective: Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. Methods: Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. Results: Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. Conclusion This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Objective: We revised the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP), first published in 2002 and revised in 2006, 2010, 2014, and 2018, to reflect recent progress in the treatment of bipolar disorder. Methods: The questionnaires consisted of 56 items for adult patients and 7 items for child/adolescent patients, and were used to obtain the consensus of experts regarding pharmacological treatment strategies for various phases of bipolar disorder. The review committee included 87 Korean psychiatrists and 40 child and adolescent psychiatry experts. Results: For treatment of manic episodes, a combination of a mood stabilizer (MS) and atypical antipsychotics (AAP), or monotherapy with MS or AAP were recommended as first-line treatments. Combinations of MS and AAP, or AAP and lamotrigine (LMT) were recommended as first-line treatments for depressive episodes regardless of the severity. Monotherapy with MS, AAP, or LMT were also first-line treatments for mild to moderate depressive episodes. For mixed features, a combination of MS and AAP, or monotherapy with AAP or MS were recommended as first-line treatments, and a combination of AAP and LMT, or MS and LMT were the first-line treatments for depressive mixed state. Conclusion The recommendations of the KMAP-BP 2022 have changed from the previous version, to reflect the evolution of the social culture and healthcare system in Korea and recent evidence regarding pharmacotherapy of bipolar disorder. The KMAP-BP 2022 provides clinicians with a wealth of information regarding appropriate strategies to treat patients with bipolar disorder.

Objectives: This study revised the Korean Medication Algorithm Project for Bipolar Disorder 2018 for rapid cycling. Methods: Questionnaires to survey the expert opinion of medication for rapid cycling were completed by a review committee consisting of 87 Korean expert psychiatrists. The experts’ opinions were classified into three categories based on the lowest category in which the confidence interval fell (6.5≤ for first-line, 3.5≤ for second-line, and 3.5> for third-line treatment). Results: The first-line treatments were a combination of mood stabilizers and atypical antipsychotics, atypical antipsychotics monotherapy, or mood stabilizer monotherapy. Furthermore, a mood stabilizer with lamotrigine therapy and an atypical antipsychotic with lamotrigine combinations was the first-line treatment for a depressive episode. The first-line medications in all episodes were valproate, lithium, quetiapine, olanzapine, and aripiprazole. Risperidone was the first-line medication in manic episodes and mixed states, and lamotrigine was the first-line medication for treating depressive episodes. Conclusion Compared to the surveys in 2018, the preference for atypical antipsychotics and lamotrigine has increased, and the modalities as a second-line treatment are more diversified.

Objectives: The objective of this study was to revise the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) 2022: children and adolescents. Methods: We performed a survey, using a questionnaire comprising 23 questions according to various situations facing children and adolescents with bipolar disorders. A total of 40 of the 60 experts in child and adolescent psychiatry responded to the survey. Results: The first-line pharmacotherapeutic strategies for manic and depressive episodes in children with bipolar disorders were a combination of mood stabilizer (MS) and atypical antipsychotics (AAP). The first-line medications selected for these children were aripiprazole (treatment of choice, TOC) and risperidone. The first-line pharmacotherapeutic strategies for manic episodes in adolescents were a combination of MS and an AAP (TOC), monotherapy with MS, and monotherapy with an AAP. Lithium, valproate, aripiprazole, risperidone, and quetiapine were selected as first-line medications for these adolescents. First-line pharmacotherapeutic strategies for depressive episodes in adolescents were a combination of MS and an AAP, monotherapy with MS, and monotherapy with an AAP. The first-line pharmacotherapeutic strategies for the depressive episodes in adolescents at high risk for bipolar disorder were a combination of MS and AAP and monotherapy with an AAP. Lithium, valproate, aripiprazole (TOC), quetiapine, and risperidone were selected as first-line medications for the treatment of depressive episodes in adolescents with bipolar disorder. Conclusion It is expected that the present KMAP-BP 2022: children and adolescents will give the direction and be usefully applied by clinicians to treat children and adolescents with bipolar disorders.

Objectives: In this study, we investigated and organized the maintenance-treatment strategies for Bipolar I and II disorders outlined in The Korean Medication Algorithm Project for Bipolar disorder 2022 (KMAP-BP 2022). Methods: The questionnaire sought to survey expert opinion on medication for bipolar disorders and was completed by a review committee consisting of 87 experienced Korean psychiatrists. It comprised 56 questions, and each question included various sub-items. The questionnaire for the maintenance treatments covered overall treatment strategies after acute mood episodes in bipolar I and II disorders, the choice of mood stabilizers and atypical antipsychotics and antidepressants, duration of medication, and treatment strategies for breakthrough symptoms. Results: In the case of bipolar I disorder, mood stabilizer monotherapy, atypical antipsychotics monotherapy, and a combination of mood stabilizers and atypical antipsychotics were selected as the first-line treatments. In maintenance management of bipolar II disorder, mood stabilizer monotherapy, atypical antipsychotics monotherapy, and combinations of mood stabilizers were selected as the preferred first-line treatments. Conclusion There has been a growing body of evidence that atypical antipsychotics have a greater preference than observed in the previous KMAP-BP of 2018. Also, monotherapy of mood stabilizers or atypical antipsychotics was more frequently selected in KMAP-BP 2022 than in the KMAP-BP 2018.

Objectives: The safety and tolerability of drugs are very important to ensure compliance and efficacy in the treatment of bipolar disorders. An expert opinion survey was conducted on treatment strategies in various special clinical situations, such as patients with significant weight gain, reporting characteristic drug side effects, low drug adherence, pregnant and reproductive women, and genetic counseling. Methods: A written survey that addressed treatment strategies related to safety and tolerability was prepared. The survey focused on significant weight gain, characteristic drug side effects, low drug adherence, treatment of pregnant and reproductive women, and genetic counseling. Eighty-seven experts in the review committee completed the survey. Results: In the case of weight gain occurring during drug treatment, it was considered preferable to replace the treatment drug with a drug that caused less weight gain, such as lamotrigine, aripiprazole, or ziprasidone. If there was a significant weight gain due to the treatment drug, it was considered preferable to intervene as soon as possible. In the case of hyperprolactinemia, it was considered preferable to change the drug. It was recommended that the drug beto discontinued in case of a benign rash as seen in patients treated with lamotrigine. For improving drug adherence, there was an increased preference for long-acting injections. It was also opined that antipsychotics should be used with great caution in pregnant or reproductive women. Conclusion Treatment strategies in various clinical situations related to the safety and tolerability of drugs for bipolar disorder have been described. It is hoped that this information would be useful in practical clinical situations.

Objectives: The present study was carried out to revise the guidelines for the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) 2018. The revision was carried out based on expert opinions to facilitate clinical decisions related to the treatment of bipolar disorders in patients with comorbid physical illnesses. Methods: A 56-item questionnaire was developed; a consensus was arrived at by 87 out of 93 experts (93.5%), on the pharmacological treatment strategies to be used in cases of comorbid physical illnesses accompanying bipolar disorders. Results: For patients with bipolar disorder exhibiting comorbid conditions, by consensus, lamotrigine, aripiprazole, and ziprasidone were recommended as the first-line strategies for metabolic syndrome; lamotrigine and aripiprazole were the recommended first-line strategies for cardiovascular problems; lithium and aripiprazole were the recommended first-line strategies for haptic problems; valproate, lamotrigine, aripiprazole, and quetiapine were the recommended first-line strategies for renal problems; and valproate and aripiprazole were the recommended first-line strategies for cerebrovascular problems or cerebral damage. Conclusion The present study is the most recent consensus among experts on recommendations for the treatment of bipolar disorders in patients with comorbid physical illnesses. Aripiprazole was recommended as the first-line pharmacotherapeutic agent in five comorbid physical conditions. This recommendation is similar to KMAP-BP 2018. Additionally, lamotrigine has been added as a first -line pharmacotherapeutic agent in patients with the metabolic syndrome, cardiovascular problems, and renal problems in the current algorithm.
