BACKGROUND: The pathologic distinction between high-grade prostate adenocarcinoma (PAC) involving the urinary bladder and high-grade urothelial carcinoma (UC) infiltrating the prostate can be difficult. However, making this distinction is clinically important because of the different treatment modalities for these two entities. METHODS: A total of 249 patient cases (PAC, 111 cases; UC, 138 cases) collected between June 1995 and July 2009 at Seoul St. Mary's Hospital were studied. An immunohistochemical evaluation of prostatic markers (prostate-specific antigen [PSA], prostate-specific membrane antigen [PSMA], prostate acid phosphatase [PAP], P501s, NKX3.1, and α-methylacyl coenzyme A racemase [AMACR]) and urothelial markers (CK34βE12, p63, thrombomodulin, S100P, and GATA binding protein 3 [GATA3]) was performed using tissue microarrays from each tumor. RESULTS: The sensitivities of prostatic markers in PAC were 100% for PSA, 83.8% for PSMA, 91.9% for PAP, 93.7% for P501s, 88.3% for NKX 3.1, and 66.7% for AMACR. However, the urothelial markers CK34βE12, p63, thrombomodulin, S100P, and GATA3 were also positive in 1.8%, 0%, 0%, 3.6%, and 0% of PAC, respectively. The sensitivities of urothelial markers in UC were 75.4% for CK34βE12, 73.9% for p63, 45.7% for thrombomodulin, 22.5% for S100P, and 84.8% for GATA3. Conversely, the prostatic markers PSA, PSMA, PAP, P501s, NKX3.1, and AMACR were also positive in 9.4%, 0.7%, 18.8%, 0.7%, 0%, and 8.7% of UCs, respectively. CONCLUSIONS: Prostatic and urothelial markers, including PSA, NKX3.1, p63, thrombomodulin, and GATA3 are very useful for differentiating PAC from UC. The optimal combination of prostatic and urothelial markers could improve the ability to differentiate PAC from UC pathologically.

Purpose:
This study investigates the impact of self-myofascial release using a foam roller on the quadriceps femoris for pelvic stability.We further compare the effects of a GRID surface Foam Roller (GFR), a Non-Vibration Foam Roller (NVFR), and a Vibration Foam Roller (VFR).
Methods:
Thirty healthy adults (15 males, 15 females) participated in this study and were randomly assigned to one of three conditions:GFR, NVFR, or VFR. Participants walked at self-selected speeds with an arm sling before and after foam roller stretching. The analyzed gait parameters included pelvic tilt, pelvic obliquity, and pelvic rotation.
Results:
In the NVFR and VFR groups, there was a Significant differences were obtained in the pelvic tilt between pre-test and post-test values (p< 0.05) in the NVFR and VFR groups, but no significant difference was observed in the GFR group (p> 0.05). Comparing the amount of change between the three groups exhibited a significant decrease in pelvic tilt in the NVFR and VFR groups compared to the GFR group (p< 0.017). No significant differences were found in pelvic obliquity and pelvic rotation (p> 0.05) in all groups.
Conclusion
While walking, the use of a VFR for self-myofascial release results in pelvic alteration by reducing the anterior pelvic tilt. We propose that a foam roller can be utilized to enhance pelvic stability during gait.

Almost all cases of acute methanol intoxication result from ingestion. Absorption of methanol following oral administration is rapid and peak concentration occurs within 30-60 min. Foromic acid converted metabolites of methanol are responsible for its toxic effect. Methanol poisoning typically induces nausea, vomiting, abdominal pain, and mild central nervous system depression. Then there is a latent period lasting, followed by an uncompensated metabolic acidosis and visual dysfunction, depending on the dose of methanol ingested. Here we report on three patients who were victims of methanol intoxication due to ingestion of windshield washer fluid, which was misidentified as an alcoholic beverage. One patient had a mild form, which included abdominal discomfort, another patient had a moderate case, which included nausea, vomiting, and acidosis, and the other patient had severe acidosis and altered mentality and visual dysfunction. Except one case of visual dysfunction, all three patients recovered successfully following medical treatment and hemodialysis.

PURPOSE: To evaluate the concentrations of commercially available ofloxacin 0.3%, levofloxacin 0.5%, and ciprofloxacin 0.3% topical ophthalmic solutions in human aqueous humor. METHODS: Patients scheduled to undergo phacoemulsification and posterior chamber lens insertion for treatment of cataract were enrolled in this prospective study. After informed consent was obtained, patients were randomized to receive 1 drop of ofloxacin 0.3%, levofloxacin 0.5%, or ciprofloxacin 0.3% topical ophthalmic solution 5 times at 1-hour intervals from 6pm one day before surgery and 3 further times at 5-min intervals immediately before surgery. After aspirating approximately 0.1 mL of aqueous fluid by paracentesis, surgery was commenced. We recorded the interval between the last drop and paracentesis. Specimens were stored at -70 degrees C until assayed by high-performance liquid chromatography. RESULTS: Thirty-four patients were enrolled. 14 male and 19 patients female. The mean age was 59.4 years. The mean concentrations of levofloxacin, ofloxacin and ciprofloxacin in aqueous humor were 577.8 ng/ml, 279.6 ng/ml and 53.0 ng/ml, respectively. The differences of concentration among the three groups were statistically significant. CONCLUSIONS: The concentration of levofloxacin 0.5% solution was highest, followed in order by ofloxacin 0.3% and ciprofloxacin 0.3%.

Pneumococcus is the most frequently encountered causative pathogen in community-acquired pneumonia in elderly patients. The pneumococcal polysaccharide vaccine (PPV23) is widely used for preventing pneumococcal diseases in adults. PPV23 is relatively safe; however, some cutaneous adverse reactions, including localized mild inflammation associated with erythema, a sensation of heat, and tenderness, have been reported. Systemic reactions such as myalgia, arthralgia, and headache have also been reported, though severe adverse reactions are rare. In the Korean literature, a case of localized toxic reaction near the injection site after pneumococcal conjugate vaccine (PCV13) administration was previously reported. However, there are no published reports of a generalized skin rash after PPV23. Herein, we report a case of PPV23-induced generalized skin rash on the face, neck, upper trunk, and both arms with a local adverse reaction at the injection site after vaccination.

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.

BACKGROUND AND PURPOSE: Hyperhomocysteinemia is supposed to be a risk factor for vascular occlusive disease. We want to evaluate the relationship between plasma homocysteine and the severity of coronary artery disease (CAD). METHODS: In 121 consecutive patients (men:62%: age:60+/-10 years) undergoing coronary angiography, plasma homocysteine, vitamin B(12), vitamin B(6) and folate levels were measured and angiographic findings were evaluated for the number of diseased vessels (diameter stenosis 50%), severity of stenosis of CAD and extent of CAD. Extent of CAD was defined as an index derived by assigning a score of 0-3 per segment depending on the proportion of lumen length irregularity and dividing the sum by the number of visualized segments. RESULTS: Twenty-two patients had normal coronary artery: 35 patients, minimal CAD (diameter stenosis < 50%): 30 patients, 1 vessel disease (VD): 22 patients, 2VD and 12 patients, 3VD. Homocysteine levels w+re not significantly different between the groups (normal:7.6+/-4.2 mmol/L: minimal CAD:8.4+/-3.1mmol/L: 1VD: 8.0+/-4.8mmol/L: 2VDs: 10.2+/-6.0 mmol/L: 3VDs: 9.2+/-5.3 mmol/L). There was no relation between the stenosis scores of CAD and homocysteine levels (r=0.1). The extent scores of CAD were weakly correlated to the plasma homocysteine levels (r=0.22, p<0.05) and low density lipoprotein (LDL) cholesterol levels (r=0.28, p<0.01), and reversely correlated to high density lipoprotein (HDL) cholesterol levels (r=-0.31, p<0.01). The plasma homocysteine levels were reversely correlated to vitamin B12 (r=-0.27, p<0.01) and folate (r=-0.23, p<0.05) levels. In conclusion, the plasma homocysteine level was weakly but significantly correlated with the extent of CAD, not with the severity of stenosis.

Primary cutaneous anaplastic large cell lymphoma (PCALCL) is a rare cutaneous T-cell lymphoma. Most cases are composed of large anaplastic cells. However, it presents a wide spectrum of histologic patterns. In the small cell variant, a small-sized pleomorphic cell morphology can be seen. A 74-year-old woman presented with an 8-month history of asymptomatic ulcerative plaque and satellite nodule on the right calf. Her past medical history was not specific. The histologic findings on punch biopsy specimens showed a malignant small round cell tumor on both lesions. The tumor cells had large pleomorphic nuclei with multinucleation and some eosinophilic cytoplasm. We performed immunohistochemical staining to rule out neuroectodermal tumor, neuroendocrine tumor, melanoma, lymphoma, and so on. However, the staining results were negative for pancytokeratin, CD3, CD20, CD99, chromogranin A, synaptophysin, CD56, ALK, HMB45, desmin, kappa, lambda, myoglobin, and S-100 protein. CT, MRI, and PET-CT were negative for extracutaneous involvement. Total excision was done, and additional immunohistochemical staining was performed to confirm the origin of the tumor. Staining results for vimentin, LCA, CD4, and CD30 were positive. We concluded that these findings were consistent with the small cell variant CD30+ PCALCL, which occurs rarely.
