Objective : The Korean Association of Anxiety Disorders developed Korean guidelines for treatment of panic disorder (PD) 2018. In this paper, we discussed the consensus among psychiatrists, regarding initial and maintenance treatment strategies for pharmacological treatment of PD in Korea. Methods : Based on current treatment guidelines published by the American Psychiatric Association, the National Institute for Clinical Excellence, and the Canadian Psychiatric Association, we developed questionnaires pertinent to initial and maintenance treatment strategies for pharmacological treatment of PD. Seventy-two experts in PD answered questionnaires. We classified expert opinions into three categories, first, second, and third-line treatment strategies, by analyzing the 95% confidence interval. Results : Antidepressants, benzodiazepine anxiolytics, and cognitive-behavioral therapy (CBT) were recommended as treatments of choice (ToC), and first-line strategies for initial treatment of PD. Escitalopram, paroxetine, sertraline, and venlafaxine were preferred from among many anti-panic drugs. Mean starting dose of anti-panic drugs for initial treatment of PD was relatively lower, than that for other psychiatric illnesses such as major depressive disorder. In the case of maintenance treatment of PD, antidepressants and CBT were selected as ToC and first-line strategies. Patients were typically examined every four weeks during treatment, to review effectiveness and side effects of the drug. Pharmacotherapy was generally continued for one year or more. Conclusion : This study provides information about consensus among Korean experts regarding pharmacological treatment strategies for patients with panic disorder.

우울증은 우울한 기분, 무쾌감증, 피로 및 인지 기능 변화를 특징으로 하는 정신질환으로 일상 기능의 저하를 초래한다. 또한, 우울증은 개인의 삶뿐만 아니라 사회적으로도 심각하고 흔한 정신질환이므로 적극적인 치료가 필요하다. 자가소화작용은 정신질환의 병태생리학적 기전에 관여한다. 최근 연구에 따르면, 자가소화작용에 의한 세포사멸이 신경가소성에 영향을 주어 우울증을 유발하고, 항우울제가 자가소화작용을 조절한다고 알려져 있다. 자가소화작용은 용해소체를 통해 불필요한 세포소기관이나 단백질을 분해하고 제거하는 이화과정이다. 그리고, 세포의 항상성을 유지하는데 필수적이다. 자가소화작용은 스트레스 상황에서 활성화되며 우울증은 스트레스 관련 질병이다. 최근, 신경세포에서 자가소화작용 기전의 역할이 조사되고 있지만, 우울증의 자가소화작용은 완전히 연구되지 않았다. 이 리뷰에서 우울증의 병태생리학적 기전과 치료에 자가소화작용이 관여한다는 새로운 증거를 강조하고자 한다. 증거를 강조하기 위해 자가소화작용이 우울증과 관련되어 있음을 보여주는 임상 및 전임상 연구결과들을 소개한다. 우울증에 대한 자가소화작용의 관련성과 연구의 한계를 이해하는 것은 자가소화작용 조절이 항우울제 개발의 새로운 방향을 제공할 것으로 사료된다.

In the Linford group at Brigham Young University we have recently developed three new sets of materials for three different areas of separations science: thin layer chromatography (TLC), high performance liquid chromatography (HPLC), and solid phase microextraction (SPME). First, via microfabrication we have grown patterned carbon nanotube (CNT) forests on planar substrates that we have infiltrated with inorganic materials such as silicon nitride. The coatings on the CNTs are conformal and typically deposited in a process like low pressure chemical vapor deposition. The resulting materials have high surface areas, are porous, and function as effective separation devices, where separations on our new TLC plates are typically significantly faster than on conventional devices. Second, we used the layer-by-layer (electrostatically driven) deposition of poly (allylamine) and nanodiamond onto carbonized poly (divinylbenzene) microspheres to create superficially porous particles for HPLC. Many interesting classes of molecules have been separated with these particles, including various cannabinoids, pesticides, tricyclic antidepressants, etc. Third, we have developed new materials for SPME by sputtering silicon onto cylindrical fiber substrates in a way that creates shadowing of the incoming flux so that materials with high porosity are obtained. These materials are currently outperforming their commercial counterparts. Throughout this work, the new materials we have made have been characterized by X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, scanning electron microscopy, transmission electron microscopy, etc.

Venlafaxine is among the most widely prescribed antidepressants. It is extensively metabolized to O-desmethylvenlafaxine via cytochrome P450 (CYP) 2D6. We report a case of acute toxic hepatitis resulting from venlafaxine in a 54-year-old woman with pain disorder. During venlafaxine treatment, laboratory tests revealed elevated liver enzymes with a maximum of 169 IU/L for aspartate transaminase (AST) and 166 IU/L for alanine transaminase (ALT). AST and ALT levels returned to normal after 6 days of discontinuation of venlafaxine. The patient was finally diagnosed with acute toxic hepatitis through liver biopsy. This case indicates the importance that clinicians should be aware of the hepatotoxicity of venlafaxine in practice.

Whenever a clinician manages the patients with depression, he may meet various problems that make it difficult to treat them. Even though he has good skills and knowledge about depression, some barriers will be appear during his practice. In general, the difficulties in treating depression are treatment-resistance, adverse effects of antidepressants, pregnancy in female patients, comorbid medical conditions, poor compliance, drug-drug interactions, and so on, which are related with pharmacological treatments. Here, only the two of them, the treatment-resistant depression and difficult problems concerned with pregnancy, were discussed. Some level of treatment resistance is the norm rather than the exception. As the treatment failure stems from inadequate treatment, it is important that the clinician should prescribe medications with sufficient doseage and adequate duration. And to overcome the treatment resistant depression the polypharmacy is necessary, in that case, the side effects and toxicities should be explored and managed immediately. So the clinician have to learn more about the pharmacokinetic and pharmacodynamic mechanisms of each drugs used in treatment of depression. When the risk of the fetus by the exposure is higher than the risk of untreated maternal psychiatric disorder, psychotropic medications should be used during pregnancy. Women who are maintained on psychotropics and become pregnant, as well as women with the new onset of psychiatric symptoms during pregnancy, should be carefully reassessed. However, data concerning the potential risk of long-term behavioral changes following prenatal exposure to psychotropics is rare, so further longitudinal follow-up studies are needed.

At the beginning, researches on the biology of depression or affective illness have focused mainly on the receptor functions and neuroendocrine activities. And the studies of the past years did not break new theoretical background, but the recent advances in the research on the molecular mechanisms underlying neural communication and signal transduction do add some insights to many established ideas. This article will overview some of the more recent advances in the clinical researches of depression. Our major concerns to be presented here include the followings : (1) alterations in the post-synaptic neural transduction ; (2) changes in the neurons of hypothalamic neuropeptides ; (3) decreased peptidase enzyme activities ; (4) associations of hypothalamic-pituitary-adrenal axis abnormalities with serotonin neurotransmission ; (5) role of serotonin transporter ; (6) changes in the responsiveness of intracellular calcium ion levels ; (7) the inositol deficiency theory of lithium and depression ; (8) the transcription factors including immediate early genes ; (9) recent genetic studies in some families. This brief overview will suggest that changes in DNA occur during antidepressant therapy. These changes at the DNA level initiating a cascade of events underlying antidepressant modality will give us the insights on the molecular biological basis of the pathogenesis of depression and cues for a new class of antidepressants.

The gastrointestinal disorders (GI disorders) is one of the most common diseases in Korea. The community pharmacists are often faced with the complaints of symptoms due to the GI disorders. However the drugs used to treat the GI disorders are frequently abused by the patients themselves because these drugs are easily available and have high placebo effects. Therefore, we have reviewed the digestive diseases statistics of 1996 to find out the frequencies of the GI disorders in the outpatients of Samsung Medical Center. Using these statistic data, we figured out the frequently diagnosed GI disorders and analysed commonly used prescriptions from February 1st to 28th of 1997. In addition, we also evaluated the commonly used drugs in these prescriptions. About twenty thousands of patients visited the hopital because of their GI symptoms in 1996. It was found that dyspepsia, viral hepatitis, and gastric and duodenal ulcer disease are frequently diagnosed in these patients. In a point of view on other GI disorders, gastritis and duodenitis, irritable bowel syndrome, gastroesophageal reflux disease, constipation and diarrhea were commonly detected. And a number of drugs were prescribed to treat the GI disorders, which included the prokinetics, Histamine-2 receptor antagonists, proton pump inhibitor, antacids, tranquillizers, antidepressants, antispasmodics, laxatives and so on. Interestingly, there were many prescriptions composing of the antibiotic regimens to eradicate H. pylori which has been proven to cause peptic ulcers.

Burning mouth disorders (sometimes referred to as burning mouth syndrome) are characterized by a burning sensation in the tongue or other oral sites, usually in the absence of clinical and laboratory findings. Affected patients often present with multiple oral complaints, including burning, dryness and taste alterations. Burning mouth complaints are reported more often in women, especially after menopause. Typically, patients awaken without pain, but report increasing symptoms through the day and into the evening. Conditions that have been reported in association with burning mouth syndrome include chronic anxiety or depression, various nutritional deficiencies, diabetes and changes in salivary function. However, these conditions have not been consistently linked with the syndrome, and their treatment has had little impact on burning mouth symptoms. Recent studies have pointed to dysfunction of several cranial nerves associated with taste sensation as a possible cause of burning mouth disorders. The most common central mechanism that likely explains burning mouth disorders is a centrally mediated continuous neuropathic pain. Given in low dosages, benzodiazepine, tricyclic antidepressants or anticonvulsants may be effective in patients with burning mouth disorders.

Chemotherapy has many known side effects. Neuropathy is a common side effect when using cisplatin. The clinical course varies and depends on the agents used and their cumulative dose. Although symptoms can resolve completely, in most patients chemotherapy-induced peripheral neuropathy is either only partially reversible or completely irreversible. Current management for chemotherapy-induced peripheral neuropathy is symptomatic relief using membrane stabilizing medications and antidepressants. Dysaesthesia and pain involving the feet and hands are described in traditional korean medicine. In traditional korean medicine, the pathogenesis is related to the inability to direct Qi and Blood to the extremities, and is associated with Qi, Blood, Yang and Kidney deficiencies. We report a case of a 52 years old female patient treated with acupuncture and bleeding treatment for the goal of improving the symptoms of chemotherapy induced peripheral neuropathy. Further study and other medical method will be needed in order to improve the effect and determine the long-term effect of traditional korean medicine in treating Chemotherapy-induced Peripheral Neuropathy.
