Lichen Striatus Occurring after Allogenic Peripheral Blood Stem Cell Transplantation in an Adult with Aplastic Anemia

Lichens striatus (LS) is an acquired, self-limiting inflammatory dermatosis that follows the lines of Blaschko. The etiology of the eruption is unknown, but several theories have been proposed with focus on environmental factors, viral infection, cutaneous injury, hypersensitivity, and genetic predisposition. We describe a 19-year-old woman who developed a unilateral linear eruption 17 months after allogenic peripheral blood stem cell transplantation. Histopathology revealed features, which were consistent with LS. To the best of our knowledge, our patient is the first case describing the appearance of LS occurring after allogenic stem cell transplantation. We speculate that this condition represents an unusual form of localized, chronic graft-versus-host disease.     

Development of web-based diabetic patient management system using short message service (SMS)

We developed a blood glucose management system using the Internet and short message service (SMS) which can lessen the social economic burden and materialize an individualized diabetes mellitus management. A total of 185 diabetic patients participated in this study and their mean age was 42.4 years old (8-79 year-old). Participants sent their self-measured blood glucose levels, medication and its dosages, amount of meal, and degree of exercise to their health providers in this specialized web-based diabetes management system for 3 months. The health providers consisting of endocrinology specialists, dietitians, and nurses sent recommendations for individualized diabetes management according to the data on the web. Laboratory tests including lipid profiles and glycated hemoglobin (HbA1c), and a survey of satisfaction about this system were performed before and after the study period. The mean HbA1c improved from 7.5 +/- 1.5 to 7.0 +/- 1.1% after using the management program (P = 0.003). The mean serum triglyceride and HDL-cholesterol levels turned for the better also. HbA1c improved from 8.4 +/- 1.2 to 7.5 +/- 1.0% after applying this program to patients with the HbA1c of 7% or higher at baseline (P = 0.010). We propose this web-based diabetic patient management system as a new tool for communication between health care providers and patients.     

Phase II Study of Combination Chemotherapy with Etoposide and Ifosfamide in Patients with Heavily Pretreated Recurrent or Persistent Epithelial Ovarian Cancer

The aim of this trial was to investigate the efficacy and toxicity of combination chemotherapy with etoposide and ifosfamide (ETI) in the management of heavily pretreated recurrent or persistent epithelial ovarian cancer (EOC). Patients with recurrent or persistent EOC who had measurable disease and at least two prior chemotherapy participating in this phase II trial were to receive etoposide at a dose of 100 mg/m²/day intravenously (IV) on days 1 to 3 in combination with ifosfamide 1 g/m²/day IV on days 1 to 5, every 21 days. Thirty-seven patients were treated; about 78% had previously received more than two separate regimens. The response rate (RR) was 18.9% and median duration of response was 7 months (range, 1-15). Treatment free interval prior to ETI (TFI) has significant correlation with RR rate (P=0.034). Patients (n=6) with TFI ≥6 months had 50% of RR, while patients (n=31) with TFI <6 months had 12.9%. Median survival was 9 months at a median follow-up of 9.2 months. Grade 3 or 4 toxicities included neutropenia in 20.1% of the 139 cycles of ETI, anemia in 7.2% and thrombocytopenia in 8.6%. The ETI produces relatively low toxicity and modest activity in heavily pretreated recurrent or persistent EOC. This is significant in patients with TFI ≥6 months.     

Prognostic significance of VEGF expression in patients with bulky cervical carcinoma undergoing neoadjuvant chemotherapy

Background  

The prediction of response to treatment would be valuable for managing cervical carcinoma with neoadjuvant chemotherapy.     

Insulin-like growth factor binding protein 2 promotes ovarian cancer cell invasion

Background  

Insulin-like growth factor binding protein 2 (IGFBP2) is overexpressed in ovarian malignant tissues and in the serum and cystic fluid of ovarian cancer patients, suggesting an important role of IGFBP2 in the biology of ovarian cancer. The purpose of this study was to assess the role of increased IGFBP2 in ovarian cancer cells.     

Selected adnexal cystic masses in postmenopausal women can be safely managed by laparoscopy

The aim of this study was to assess the efficacy and safety of laparoscopic treatment for adnexal cystic masses that were predicted to be benign in postmenopausal women. Postmenopausal women found to have an adnexal cystic mass were retrospectively evaluated with transvaginal ultrasonography, and serum CA-125 levels. The selection criteria were adnexal cystic masses greater than 3 cm but less than 10 cm, the masses were in the benign range (4-8) of Sassone's scoring system for transvaginal ultrasonography, and the patients had serum CA-125 levels less than 65 IU/mL. Two hundred nineteen women fulfilled the criteria and underwent operative laparoscopy. Almost all the masses (99.5%) were accurately predicted to be benign except for one borderline ovarian tumor. Two hundreds thirteen (97.3%) women were successfully managed by operative laparoscopy and six (2.7%) required laparotomy. For the patients managed by laparoscopy, the mean operative time was 51.3 min; the mean hospital stay was 2.5 days. There was no significant morbidity and surgery-related mortality. The combination of the Sassone's scoring system for transvaginal ultrasonography and serum CA-125 level can accurately predict benign cystic masses, and operative laparoscopy is technically feasible and safe for the management of adnexal mass in postmenopausal women.     

Synthesis and biological evaluation of 3-(4-substituted-phenyl)-N-hydroxy-2-propenamides, a new class of histone deacetylase inhibitors

Inhibitors of histone deacetylases (HDACs) have been shown to induce differentiation and/or apoptosis of human tumor cells. Novel 3-(4-substituted-phenyl)-N-hydroxy-2-propenamides have been prepared as a new class of HDAC inhibitors and evaluated for their antiproliferative activity and HDAC inhibitory activity. Incorporation of a 1,4-phenylene carboxamide linker, shown by 5, and a 4-(dimethylamino)phenyl or 4-(pyrrolidin-1-yl)phenyl group as a cap substructure generated highly potent hydroxamic acid-based HDAC inhibitors 5a and 5b.     

Metastatic urachal carcinoma of the ovary

A 52-year-old woman had undergone a partial cystectomy for a cystic mass at the dome of the urinary bladder in 1997. The pathological diagnosis was a urachal mucinous cystadenoma with borderline malignancy. Twelve years later, multiple masses were noted on the uterus, ovaries and abdominal wall. She underwent debulking surgery, including a total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymph node dissection, infracolic omentectomy, appendectomy, colon mass removal and abdominal wall mass removal. Remnants of the tumor were seeded throughout the abdominal cavity. The pathological evaluation confirmed metastatic urachal mucinous adenocarcinoma in both ovaries, the abdominal wall, the colon mass, the uterosacral ligament and the bladder. Adjuvant chemotherapy with paclitaxel and carboplatin was administered, which showed stable disease. She is now undergoing second-line chemotherapy.     

Increased expressions of claudin-1 and claudin-7 during the progression of cervical neoplasia

OBJECTIVES: Claudin proteins represent a large family of integral membrane proteins crucial for tight junction formation and function and they have been shown to be expressed differently in various cancers. We investigated whether the expressions of claudin-1 and claudin-7 are associated with the progression of uterine cervical neoplasia. METHODS: We analyzed 89 formalin-fixed paraffin embedded cervical tissues that included 10 normal cervical epithelium, 19 low-grade squamous intraepithelial lesion (LSIL), 20 high-grade squamous intraepithelial lesion (HSIL), 20 invasive squamous cell carcinoma (ISCC) without lymph node (LN) metastasis, and 20 ISCC with LN metastasis. The expressions of claudin-1 and claudin-7 were determined by immunohistochemistry. RESULTS: The expressions of claudin-1 and claudin-7 were undetectable in normal cervical squamous epithelium, but had variable staining in the basal layer of normal endocervical glands. The expressions of both proteins, mainly as membranous staining, gradually increased in accordance with the progression from LSIL to HSIL and ISCC (both P values are <0.001) and were detected in all cases of ISCC. CONCLUSIONS: These results suggest that claudin-1 and claudin-7 may play a significant role in tumor progression of cervical neoplasia and may represent useful markers for malignant transformation of cervical squamous cells. Further studies would likely result in the development of novel approaches for early detection and therapy for this disease.
