Hormone therapy (HT) is the most effective treatment for menopausal symptoms, and reduces both spinal and non-spinal postmenopausal osteoporotic fractures. However, a Women's Health Initiative (WHI) trial revealed that progestin-containing HT is associated with higher incidences of breast cancer and coronary heart disease than those associated with placebo. Tissue selective estrogen complex (TSEC) is a novel progestin-free HT option composed of conjugated estrogens (CE) and a selective estrogen receptor modulator. CE at a dose of 0.45 mg combined with 20 mg of bazedoxifene was the first TSEC medication approved in the United States and Korea for women with moderate to severe menopause-related vasomotor symptoms (VMS) and for preventing postmenopausal osteoporosis. This review summarizes the clinical efficacy, safety, and tolerability of TSEC as obtained from the five SMART clinical trials.

Uterine leiomyomas are benign tumors arising from the myometrium and largely prevalent in the woman's reproductive years. The majority of women with leiomyomas either remain asymptomatic or develop symptoms gradually over time. When patients are symptomatic, the nature of their complaints is often attributable to the number, size, and/or location of their fibroids. Depending on a patient's symptomatology and reproductive plans, treatment options include expectant management, medical management (hormonal and non-hormonal), or surgical management (myomectomy or hysterectomy).

Protein losing enteropathy (PLE) due to systemic lupus erythematosus (SLE) is relatively uncommon. PLE may be appeared sequentially after the diagnosis of SLE or concurrently with SLE. In most of concurrent cases, PLE was diagnosed one of various symptoms of SLE. Cases of PLE as the initial and only clinical presentation of SLE have been rarely reported. We described a 30-year old woman with general edema and abdominal distension was diagnosed PLE after stool alpha 1 antitrypsin clearance test. Her symptoms were getting worse even though the treatment with intravenous albumin. She was finally diagnosed PLE associated with SLE by additional laboratory findings (positive antinuclear antibody and anti-dsDNA IgG and low C3, C4 and CH50). She was treated with high dose of steroids and her symptoms were improved.

Minimal change disease (MCD) is a common cause of nephrotic syndrome and relatively well responds with steroid treatment. However, nearly half of patients with MCD experience recurrence of nephrotic syndrome. Thromboembolic events including renal vein thrombosis may occur in patients with MCD, but portal vein thrombosis rarely occurs. We experienced a case of frequent relapse/steroid dependent MCD with nephrotic syndrome progressed to steroid resistance associated with portal vein thrombosis. This patient showed complete remission of MCD and resolution of portal vein thrombosis after treatment with corticosteroid, cyclosporine, mycophenolate mofetil, and anticoagulant.

We report a case of a 65-year-old man with Behcet's disease who presented with massive hemoptysis caused by bronchial varices. A computed tomography (CT) scan and bronchoscopy were performed to identify the bleeding site. The CT scan revealed pneumonia and a combined hemorrhage in the right-middle and lower lobes. Massive bleeding was detected during the bronchoscopy and emergency embolization was attempted but angiographic findings were normal. An anteriojugulo-right femoral bypass operation was performed to relieve the tortuous and hypertrophied jugular venous obstruction. However, thrombectomy and thrombolysis followed because of graft thrombosis six days post-surgery. The patient was treated with steroid and high-dose cyclophosphamide therapy for his Behçet's disease, which caused the venous obstructions; the saccular bronchial varices in the right-middle and right lower lobes on bronchoscopy regressed slightly after four cycles of cyclophosphamide therapy

Elevated lactate levels are associated with acute illnesses, and the mortality is high. Here, we report a case of lactate-containing peritoneal dialysis (PD) solution inducing lactic acidosis corrected by changing to hemodialysis (HD). This 70-year-old female patient was treated with PD 8 months previously for end-stage renal disease caused by diabetes mellitus. She was admitted complaining of general weakness. Initial lactate level was 22.1 mg/dL and increased to 62.4 mg/dL showing high anion gap metabolic acidosis and compensatory hyperventilation. There are no definite causes of lactic acidosis besides the use of PD solutions containing a lactate component. The patient's lactate level was decreased after temporarily changing the dialysis modality to HD. Her lactate level was increased again after restarting PD, and decreased to normal after restarting HD. We report this case because physicians should consider lactate-containing PD solution as a possible cause of lactic acidosis.

Moyamoya disease is characterized by progressive stenosis of the distal portion of the internal carotid arteries and fragile collateral vessels in the brain. The precise pathogenesis is still not known. Although extracranial vessel involvement is very rare, coronary arterial involvement has recently been reported. Here, we report a case of diffuse, multivessel coronary spasm leading to cardiac arrest and myocardial infarction in a 47-year-old man with moyamoya disease with no underlying emotional or physical stress.

Sjögren's syndrome is a systemic autoimmune disease characterized by sicca symptoms and extraglandular manifestations. Anemia, leukopenia, thrombocytopenia and lymphoproliferative disorders are well-known extraglandular, hematological complications of Sjögren's syndrome. These hematologic alterations are usually mild and respond well with steroid therapy. We report a case of a 52-year-old female patient who was initially presented with thrombocytopenia. The patient was then diagnosed with primary Sjögren's syndrome and initially treated with steroid. The patient's platelet count was decreased when steroid was tapered. The dose of steroid could be effectively reduced after combined medication with hydroxychloroquine.

Use of recombinant tissue plasminogen activator (rt-PA) for the treatment of acute cerebral infarction secondary to aortic dissection is challenging because of a narrow time window and potential life-threatening complications. An 80-year-old woman with right middle cerebral artery infarction was treated with rt-PA. Although she had no history, symptoms, or sign of aortic dissection, carotid CT angiography revealed aortic arch dissection. Mediastinal widening, which did not show on initial chest X-ray, developed on follow-up chest X-ray. This observation indicates that physicians should monitor patient symptoms for signs of aortic dissection during thrombolysis and perform chest X-ray or carotid angiography immediately after thrombolysis even if the patient has no symptoms or signs of aortic dissection on onset of acute cerebral infarction.

Kearns-Sayre syndrome (KSS) is a rare multisystem mitochondrial disorder associated with progressive external ophthalmoplegia, atypical pigmentary degeneration of the retina, and complete heart block. KSS can lead to a risk of sudden death because of the potential progression of conduction abnormalities such as right or left bundle branch block or complete atrioventricular (AV) block. Here we describe the case of a KSS patient with type I diabetes who experienced syncope in the presence of complete AV block, confirmed by muscular biopsy.
