Ticlopidine hydrochloride is world-wide used antiplatelet agent that inhibit ADP pathway. Its clinical side effects are the change of the blood picture, allergic skin reaction and gastrointestinal symptoms. We report three patients with severe cholestatic hepatitis caused by ticlopidine. They developed jaundice about 20days after taking ticlopidine (500 mg/day). Infectious and immunological etiologies were excluded by serology. There was no history of alcohol or drug abuse. Their symptoms were gradually subsided for a few months after discontinuing ticlopidine.

BACKGROUND: Interest in pharmacist participation in the multidisciplinary intensive care team is increasing. However, studies examining pharmacist interventions in the medical intensive care unit (MICU) are limited in Korea. The aim of this study was to describe the current status of pharmacist interventions and to identify common pharmacologic problems requiring pharmacist intervention in the MICU. METHODS: Between September 2013 and August 2014, a retrospective, observational study was conducted in the 22-bed MICU at a university hospital. Data were obtained from two trained pharmacists who participated in MICU rounds three times a week. In addition to patient characteristics, data on the cause, type, related drug, and acceptance rate of interventions were collected. RESULTS: In 340 patients, a total of 1211 pharmacologic interventions were performed. The majority of pharmacologic interventions were suggested by pharmacists at multidisciplinary rounds in the MICU. The most common pharmacologic interventions were adjustment of dosage and administration (n = 328, 26.0%), followed by parenteral/enteral nutritional support (n = 228, 18.1%), the provision of drug information (n = 228, 18.1%), and advice regarding pharmacokinetics (n = 118, 9.3%). Antimicrobial agents (n = 516, 42.6%) were the most frequent type of drug associated with pharmacist interventions. The acceptance rate of interventions was 84.1% with most accepted by physicians within 24 hours (n = 602, 92.8%). CONCLUSIONS: Medication and nutritional problems are frequently encountered pharmacotherapeutic problems in the MICU. Pharmacist interventions play an important role in the management of these problems.

Purpose: This study aimed to investigate the diagnostic performance of features suggestive of nodal metastasis on preoperative MRI in patients with invasive breast cancer. Materials and Methods: We retrospectively reviewed the preoperative breast MRI of 192 consecutive patients with surgically proven invasive breast cancer. We analyzed MRI findings of axillary lymph nodes with regard to the size, long/short ratio, cortical thickness, shape and margin of the cortex, loss of hilum, asymmetry, signal intensity (SI) on T2-weighted images (T2WI), degree of enhancement in the early phase, and enhancement kinetics. Receiver operating characteristic (ROC) analysis, chi-square test, t test, and McNemar’s test were used for statistical analysis. Results: Increased shorter diameter, uneven cortical shape, increased cortical thickness, loss of hilum, asymmetry, irregular cortical margin, and low SI on T2WI were significantly suggestive of metastasis. ROC analysis revealed the cutoff value for the shorter diameter and cortical thickness as 8.05 mm and 2.75 mm, respectively. Increased cortical thickness (> 2.75 mm) and uneven cortical shape showed significantly higher sensitivity than other findings in McNemar’s test. Irregular cortical margins showed the highest specificity (100%). Conclusion Cortical thickness > 2.75 mm and uneven cortical shape are more sensitive parameters than other findings, and an irregular cortical margin is the most specific parameter for predicting axillary metastasis in patients with invasive breast cancer.

The central neural pathways of the sciatic and femoral nerves of the rat were identified with tracing methods of fluorogold, cholera toxin-horseradish peroxidase and Bartha strain of pseudorabies virus as neurotracers. After injections of fluorogold and CT-HRP into the femoral and the sciatic nerves respectively, the spinal cords were removed and processed for fluroscent microscopy and histochemistry. Lower motor neurons were multipolar in shape and located in the ipsilateral L3-L5 and L5-S1 segments. The location of the femoral LMN's were ventromedial to those of the sciatic nerve. There was no double labeled neurons and the lower motor neurons of the femoral nerves were located in ventromedially to sciatic LMN in the spinal cord. After injections of fluorogold and PRV-Ba into the femoral and the sciatic nerves respectively, the fluorogold labeled neurons were identified only in the ventral horn of ipsilateral L3-L5 segments and PRV-Ba labeled cells in L5-S1 segments. Besides L5-S1 segments, some PRV-Ba labeled cells were found in the ipsilateral L3-L4 segments and a portion of them were double labeled with fluorogold and PRV-Ba. Sequential tracing of retrograde labeled cells was done after injection of PRV-Ba into the femoral and sciatic nerves. The upper motor neurons of both nerves were mostly ovoid or polygonal in shape and present in the same nuclei of supraspinal central nervous system. In conclusion, lower motor neurons of the femoral and the sciatic nerves were arranged in somatotopic organization and some of them were connected with synaptic route. But the central pathways of both nerves were similar in locations.

The aim of this study was to better understand the frequency of autoimmune thyroid and diabetes antibodies in patients with type 1 diabetes mellitus (T1DM) compared with their siblings. Glutamic acid decarboxylase antibodies (GADA), islet cell antibodies (ICA), insulin autoantibodies (IAA), and thyroid autoantibodies were studied in all subjects. The rates of positive GADA and IAA were significantly higher in probands compared to in siblings (p<0.001) or controls (p<0.001). All pancreatic autoantibodies were not significantly different between the siblings and the healthy controls. Thyroid antiperoxidase antibody (TPOAb) and antithyroglobulin antibody (TGAb) were significantly different between the probands and the control subjects (p=0.002 and p=0.018, respectively). The rates of TPOAb and TGAb positivity in siblings were higher than in those of the controls, but there was no significant difference between the two groups. However, thyroid autoimmunity (TA) was significantly different among the groups (p=0.004). Siblings of the TA-positive probands were shown to have a greater prevalence of thyroid antibodies than did the controls (p=0.022), but siblings of the TA-negative probands did not have such a prevalence compared with the control subjects. The prevalence of pancreatic and thyroid antibodies positivity in probands was statistically significant compared with the siblings and the controls. Siblings of TA-positive probands revealed a greater prevalence of thyroid antibodies than did the controls. Therefore, the screening for TA in siblings, particularly siblings of TA-positive probands, is as important as it is in probands.

Purpose: The study investigated whether incorporating magnetic resonance imaging (MRI) alongside ultrasonography (US) in the preoperative evaluation is associated with differing survival outcomes between male and female breast cancer patients in a matched analysis. Additionally, clinicopathological prognostic factors were analyzed. Methods: Between January 2005 and December 2020, 93 male and 28,191 female patients who underwent breast surgery were screened. Exact matching analysis was conducted for age, pathologic T and N stages, and molecular subtypes. The clinicopathological characteristics and preoperative imaging methods of the matched cohorts were reviewed. Disease-free survival (DFS) and overall survival (OS) were assessed using Kaplan-Meier analysis, and Cox proportional hazards regression analysis was used to identify prognostic factors. Results: A total of 328 breast cancer patients (61 men and 267 women) were included in the matched analysis. Male patients had worse DFS (10-year DFS, 70.6% vs. 89.2%; P=0.001) and OS (10-year OS, 64.4% vs. 96.3%; P<0.001) than female patients. The pathologic index cancer size (hazard ratio [HR], 2.013; 95% confidence interval [CI], 1.063 to 3.810; P=0.032) was associated with worse DFS, whereas there were no significant factors associated with OS. Adding MRI to US for preoperative evaluation was not associated with DFS (HR, 1.117; 95% CI, 0.223 to 5.583; P=0.893) or OS (HR, 1.529; 95% CI, 0.300 to 7.781; P=0.609) in male patients. Conclusion Adding breast MRI to US in the preoperative evaluation was not associated with survival outcomes in male breast cancer patients, and the pathologic index cancer size was associated with worse DFS.
