Background: There is no proven primary preventive strategy for doxorubicin-induced subclinical cardiotoxicity (DISC), especially among patients without a cardiovascular (CV) risk. We investigated the primary preventive effect on DISC of the concomitant use of angiotensin receptor blockers (ARBs) or beta-blockers (BBs), especially among breast cancer patients without a CV risk.

Methods: A total of 385 patients who were scheduled for doxorubicin chemotherapy were screened.

Article Synopsis
  • Endocrine therapy is standard for ER-positive breast cancer patients, but not all benefit, highlighting the complexity introduced by ERβ and its isoforms.
  • Two retrospective studies had opposite findings on the prognostic value of ERβ isoforms in tamoxifen-treated patients, motivating this research.
  • This study found that ERβ2 expression is linked to poorer disease-free and overall survival, particularly for patients treated with tamoxifen, suggesting ERβ2 as a potential prognostic marker and therapeutic target.

Purpose: Epidemiological studies have shown that obesity is associated with an increased risk of thyroid cancer. However, the exact nature of the relationship, especially with respect to the behavior of the cancer, remains uncertain. The objective of this study was to evaluate the correlation between the body mass index (BMI) and clinicopathological features of thyroid cancer patients.

This study investigates the incidence of full-field digital mammographic (FFDM) artifacts with three systems at two institutions and compares the artifacts between two detector types and two grid types. A total of 4,440 direct and 4,142 indirect FFDM images were reviewed by two radiologists, and artifacts were classified as patient related, hardware related, and software processing. The overall incidence of FFDM artifacts was 3.

The main culprit in the pathogenesis of ischemia/reperfusion (I/R) injury is the generation of high level of hydrogen peroxide (H2O2). In this study, we report a novel diagnostic and therapeutic strategy for I/R injury based on H2O2-activatable copolyoxalate nanoparticles using a murine model of hind limb I/R injury. The nanoparticles are composed of hydroxybenzyl alcohol (HBA)-incorporating copolyoxalate (HPOX) that, in the presence of H2O2, degrades completely into three known and safe compounds, cyclohexanedimethanol, HBA and CO2.

Background: Improvements in immunosuppression have resulted in long life expectancy of kidney transplants. Unfortunately, the incidence of post-transplant malignancy (PTM) is increasing. The aim of this study was to evaluate the nature and stage-specific prognosis of post-transplant breast cancer (PTBC) compared with breast cancer in the general population, and to suggest optimal treatment strategies.

Polyoxalate and copolyoxalate were developed in the 1970s and have been used for biomedical applications such as suture coating purposes, owing to their biocompatibility and biodegradability. They are known to degrade into diols and oxalic acid, which are considered biocompatible. One of the advantages of oxalate-based polymer is the ease of control of physicochemical properties, such as biodegradability, crystallinity and mechanical strength.

Background: Cervical lymph node metastases are quite common in papillary thyroid cancer (PTC) and they usually spread in a contiguous fashion. However, "skip metastasis," defined as lateral lymph node metastasis without central lymph node metastasis, also occurs in patients with PTC. There is little information regarding skip metastasis in papillary thyroid microcarcinoma (PTMC).

To examine the levels of PCDD/DFs pollution in environmental samples in the vicinity of various incinerators, the levels of PCDD/DFs in air and soil samples collected near 17 incinerators and stack emission gases were investigated between 2003 and 2006. A total of 434 soil, 28 stack emission gas, and 38 air samples were analyzed for their PCDD/DFs concentrations. The PCDD/DFs concentrations in the flue gas samples ranged from 0.

Purpose: We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma.

Methods: A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye.

Purpose: To evaluate the effect of the simulation method on recurrence among the patients who received radiotherapy after breast-conserving surgery (BCS) for early breast carcinoma.

Materials And Methods: Between 1995 and 2000, 70 patients with stage I-II breast carcinoma underwent breast-conserving surgery and adjuvant radiotherapy. Twenty nine patients (41.

In the present study, individual PCB congeners were determined in the flue gases of 10 industrial and 5 municipal solid waste incinerators using HRGC/HRMS. The total PCBs concentration of all congeners (168 tetra to deca-chlorinated congeners) ranged from 26 to 343 ng/Nm(3), and from 36 to 1095 ng/Nm(3) in industrial waste incinerators (IWI) and municipal solid waste incinerators (MSWI), respectively. The total TEQ concentrations of PCBs, calculated using WHO-TEF values, varied from 0.

Purpose: Breast-conserving therapy (BCT) is a practical alternative to mastectomy for treating ductal carcinoma in situ (DCIS). We reviewed our experience for treating patients with DCIS of the breast to evaluate the outcome after performing breast-conserving surgery plus radiotherapy (BCS-RT).

Materials And Methods: Between January 1983 and December 2002, 25 patients with clinically or mammographically detected DCIS were treated by BCS-RT.

We describe a technique for knotting a suture to the haptic of a dislocated intraocular lens (IOL) through a sclerotomy site without removing an IOL in 4 patients. The suture was knotted to the haptic from outside the sclera. The remaining suture material was tied together and buried in the sclerotomy site.

We present a 53-year-old man with a crystalline lens that spontaneously dislocated anteriorly with corneal touch and secondary glaucoma. A dry anterior vitrectomy and partial intercapsular lensectomy were performed using a limbal approach to control intraocular pressure (IOP) and decrease the lens volume. The lens capsule was gently separated from the corneal endothelium with viscoelastic material, after which a bimanual lensectomy was performed with a vitrectomy probe and a phacoemulsification microflow tip.

The aim of this study was to evaluate the clinical outcomes of scleral fixation of a posterior chamber intraocular lens and an anterior vitrectomy through sclerotomies, 1 mm posterior to the limbus. The study comprised of seven eyes that required a scleral fixation. Sclerotomies, 1 mm posterior to the limbus, were performed using a 20G sclerotome at the 2 and 8 o'clock positions.

To the best of our knowledge, isolated bilateral oculomotor nuclear palsy has not yet been reported in the literature, while bilateral oculomotor nuclear palsy with more widespread rostral brainstem infarction has often been reported. We present a patient having 'top of the basilar syndrome' with midbrain infarction selectively involving the bilateral oculomotor nucleus. A 61-year-old woman with two episodes of vertebrobasilar infarction presented with sudden onset of bilateral ptosis.

A brain lesion located at the lateral side of the sella turcica can produce a junctional scotoma by compressing the ipsilateral optic nerve and the contralateral inferonasal nerve fiber. This study reports a female patient with a junctional scotoma caused by a cerebral aneurysm. At the initial visit, she complained of visual disturbance in both eyes and the right optic disc was atrophied.

In normal breast, Bcl2 is expressed in the non-pregnant and non-involuting mammary epithelium. The exact mechanism and the effect of the down regulation of the Bcl2 expression on breast cancer cells are not clearly defined. We compared down regulation as well as the persistent expression of Bcl2 with ER, PR, p53, and c-erb-B2 overexpression and clinicopathologic variables, and tumor stage in 11 cases of ductal carcinomas in situ (DCIS) and 44 cases of invasive ductal carcinomas (IDC) of Korean women by immunohistochemical studies.
