In 1971, Dr. Akira Endo succeeded in isolating a cholesterol synthesis inhibitor, compactin. Later, compactin was renamed mevastatin, meaning that it stops the synthesis of mevalonate, which is considered the first statin. However, mevastatin is not commercially released, whereas lovastatin, developed by Alfred Albert of Merk in 1979, was the first commercially developed statin. After the 4S study, the first largescale clinical trial with statins conducted in Scandinavia showed a dramatic secondary preventive effect against cardiovascular disease, and the effectiveness of statins in patients with dyslipidemia was repeatedly demonstrated. Subsequently, many oral drugs that affect blood lipid concentration; statins and ezetimibe aimed at reducing low-density lipoprotein (LDL)) cholesterol; fibrates and omega 3 formulations aimed at reducing triglycerides were widely developed and used in Korea. In this article, we review the results of clinical studies on representative cardiovascular diseases for four types of oral drugs for dyslipidemia, which are currently the most commonly used in Korea.

Objectives The present study examined the recent domestic and international trends of non-surgical treatment of lumbar spinal stenosis (LSS). Methods The studies on non-surgical treatment of LSS were investigated via searching Korean web databases and PubMed. As a result, 39 studies were analyzed according to the authors, the types of study, the relationship to surgical treatment and the method of treatment. Results The first authors' occupations were identified as 17 doctors, 12 Korean medicine doctors, six physiotherapists, three chiropractic doctors and one doctor of science. The most common type of study in Korea was the case report and most of the studies were retrospective. Overseas, there were many prospective or experimental studies including randomized controlled trials (RCT). In Korea, non-surgical treatment was performed independently of surgical treatment in most cases. Among non-surgical treatments, the most researched treatment was traditional Korean medicine (TKM), followed by injection therapy, exercise therapy, and physical therapy. Conclusions Through this review, we can determine the effectiveness of TKM and its research direction. TKM should be studied experimentally including RCT and it should be conducted not only on acupuncture, but also on other treatment methods such as acupotomy, chuna, and herbal medicine. It is also necessary to conduct studies on TKM before and after surgery to compare the effects of surgery and TKM together, as well the effects on non-surgical treatments.

Objective: To confirm the safety of Intra-articular (IA) injection on the ipsilateral adhesive capsulitis (AC) after breast cancer surgery. Methods: Between January 2017 and May 2020, we retrospectively studied 29 patients after breast cancer surgery who underwent IA injection in the glenohumeral joint for AC in aseptic procedure. Results: There were no side effects or complications such as lymphedema or cellulitis in the patients. There was a significant improvement in pain score and range of motion (ROM) at the 1st, 3rd, and 6th months visits compared to the baseline (p<0.05). The presence or absence of axillary lymph node dissection and radiation therapy had no significant difference in improvement of ROM. But, in rotator cuff syndrome (RCS) group, there was a significant difference in improvement of shoulder IR in patients without RCS. Conclusion: IA Injection on the ipsilateral AC after breast cancer surgery was safe and even effective to improve pain and shoulder ROM. Ipsilateral IA injection can be a good treatment for breast cancer surgery patients suffering from AC.

Rapidly destructive arthrosis is a rare syndrome characterized by narrowing of the joint space and rapid joint destruction within 6~12 months. A 62-year-old woman with anaplastic lymphoma kinase rearranged non-small-cell lung cancer presented with both knee pain and varus deformity. She was treated with crizotinib 500 mg/day for more than 2 years, with partial tumor response. Initial plain radiography showed Kellgren and Lawrence (K-L) grade 1. After 10 months, varus deformity was worsened and plain radiography aggravated to K-L grade 4 despite conservative treatment including activity modification. Diffuse synovitis with massive joint effusion and destruction of anterior cruciate ligament, medial meniscus, medial collateral ligament, and lateral collateral ligament were shown in magnetic resonance imaging. The patient was diagnosed with rapidly destructive arthrosis of knee and underwent a both total knee arthroplasty.

Spinal accessory neuropathy (SAN) is commonly caused by an iatrogenic procedure, and that caused by tumors is very rare. We present a case of a 49-year-old man suffering from weakness in the right trapezius and sternocleidomastoid muscle. An electrophysiology study confirmed proximal SAN. Fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) revealed a diffuse large B-cell lymphoma compressing the right spinal accessory nerve. Ultrasonography showed definite atrophy on the trapezius and sternocleidomastoid muscles. In addition, post-chemotherapy FDG-PET/CT showed increased FDG uptake in the right upper trapezius, suggestive of denervation. This is the first report of SAN caused by direct compression by a diffuse large B-cell lymphoma, comprehensively assessed by an electrophysiology study, ultrasonography, and FDG-PET/CT.

Acute puerperal uterine inversion is a rare postpartum obstetric complication; however, without rapid diagnosis and appropriate management, it is life-threatening. Substantial bleeding hinders the verification of a partially inverted uterus, possibly delaying the treatment. Herein, we present the report of a 32-year-old female presenting with massive postpartum bleeding managed by uterine artery embolization. The peculiar course of the uterine artery bowing inferiorly along the inverted fundus during embolization could uncover the uterine inversion, which was not diagnosed by physical examination and CT. In conclusion, uterine artery embolization is not only an effective therapeutic strategy for postpartum hemorrhage but also a valuable tool for diagnosing uterine inversion.

Rosai-Dorfman Disease (RDD) is a rare lymphoproliferative disease, and the occurrence of isolated intracranial RDD is extremely rare. Most cases of intracranial RDDs present as dural masses showing homogenous enhancement on MRI, which makes it difficult to differentiate these masses from meningiomas before surgery unless massive cervical lymphadenopathy is observed. We herein report a rare case of isolated intracranial RDD in a 65-year-old male. Brain MRI revealed a well-defined enhancing mass-like lesion involving the right frontal convexity and subtle diffusion restriction. However, only a subtle blush was observed on the preoperative cerebral angiogram. Although instances of isolated intracranial RDD are rare, it should be considered as a potential differential diagnosis when a dural mass with hypovascularity is visualized on the cerebral angiogram.

Botryoid Wilms tumor, a very rare variant of Wilms tumor, arises from the pelvocalyceal system, and its occurrence in the fetal or neonatal period has never been reported in the literature. Herein, we report an exceedingly rare and challenging case of botryoid Wilms tumor in a neonate who initially presented with fetal hydronephrosis. Postnatal ultrasonography revealed multiple lobulating hypoechoic masses with varying degrees of intralesional vascularity within the dilated pelvocalyceal system. To our knowedge, this is a case report of botryoid Wilms tumor of the youngest child in English literature.

The authors report a successful thrombectomy using the AngioJet Rheolytic Thrombectomy System (AngioJet) and an embolic protection device in a patient with femorofemoral bypass graft occlusion. Lower extremity CT angiograms showed occlusion in the left-to-right femorofemoral bypass graft. A rheolytic thrombectomy using the AngioJet and balloon angioplasty restored blood flow to the right lower extremity, and distal embolization may be effectively prevented by placing an embolic protection device within the right superficial femoral artery during the procedure.

In this case report, we present the radiologic and pathologic findings of atypical ductal hyperplasia (ADH) in the male breast. It is well known that a high-risk lesion such as ADH is a precursor of breast cancer in females. However, the clinical significance of these lesions in the male breast is still uncertain because male breasts mainly consist of ducts without lobule formation, unlike the female breast. To our knowledge, imaging findings of ADH in the male breast have not been reported previously, except for a few studies on the pathologic findings of these lesions. Through this paper, we would like to present the possible imaging features of this high-risk lesion in the male breast and review the related literature.
