A supernumerary ovary is a rare gynecological anomaly, and is usually excised due to its malignant transformation potential. We report a case of a supernumerary ovary and endometriosis situated on ...the anterior rectosigmoid colon. When laparoscopy was conducted, a firm, 5-cm mass was discovered on the anterior rectosigmoid colon along with normal ovaries. In this case, the discovery of a supernumerary ovary implied the presence of endometriosis. It is unusual for endometriosis and a supernumerary ovary to exist simultaneously.
7 Gb/s/pin operation without bank group restriction in a GDDR5 SDRAM is achieved by skewed control logic and current-mode I/O sense amplifiers with regular calibration from replica impedance ...monitors. The bank-to-bank active time is shortened to 2.5 ns by a FIFO-based BLSA enabler, 2.0 ns latency V PP generator and active jitter canceler. The chip is fabricated in a 50 nm DRAM process in a 61.6 mm 2 die area.
Objective
The present study aimed to determine the differences in outcomes between natural orifice transluminal endoscopic surgery-assisted vaginal hysterectomy (NAVH) and conventional ...laparoscopy-assisted vaginal hysterectomy (LAVH).
Methods
We retrospectively reviewed the charts of patients who between July 2012 and September 2015, were diagnosed as having benign uterine disease such as uterine myoma, endometriosis, or adenomyosis and managed via NAVH or LAVH in a single-center (Eulji University Hospital). Data such as age, body weight, height, parity, operation time, intra/ post-operative complications, and uterus weight were obtained from the clinical charts. NAVH and LAVH recipients were matched 1:3 in terms of baseline characteristics, and the 2 groups were compared regarding surgical outcomes.
Results
Of the 160 patients with benign uterine disease included in the present study. Forty received NAVH and remaining 120 received LAVH. There were significant differences between the groups regarding operation time and hemoglobin change. Notably, although the operation time was shorter for LAVH, hemoglobin change was lower for NAVH. Additionally, although maximum hospitalization duration was shorter for LAVH, the average length of hospitalization was similar between NAVH and LAVH. There were no significant differences between the groups in terms of other variables.
Conclusion
NAVH may become a new alternative surgical method of choice for hysterectomy, as it represents a clinically feasible and safe approach; moreover is superior to LAVH in terms of bleeding loss.
Monopolar radiofrequency (RF) non-invasively tightens and rejuvenates the skin by stimulating collagen fiber production. Since the introduction of the monopolar RF device in the early 2000's, RF ...devices have advanced and they can rejuvenate of periorbital and forehead wrinkles, as well as skin laxity of the lower face and neck. We compared the differences in the treatment effects based on the tip size. This randomized split-face study comprised 31 participants aged 29 to 75 years old (three males and 28 females) who underwent one session of monopolar RF; one side of the face was treated with a 3cm
tip and the other with a 4cm
tip. Facial wrinkle scores were measured on the upper face and the lower face before and after treatment for up to three months. Significant improvement was observed in the periorbital area (
<0.001), forehead (
=0.72), and glabellar (
=0.63) treated with a smaller tip. However, nasolabial folds (
=0.8) and marionette lines (
=0.13) showed better improvement when treated with a larger tip.
An atypical clinical form of pityriasis versicolor has been infrequently reported, in which cutaneous atrophy is associated with individual pityriasis versicolor lesions. The pathogenesis of this ...atrophy remains unclear, but is believed to be a delayed-type hypersensitivity reaction to antigens derived from the Malassezia species. A 60-year-old man presented with multiple, slightly scaly, and depressed maculopatches or plaques on the trunk and extremities. Our microscopic examination of the skin scrapings on a KOH preparation revealed numerous short hyphae and spores. The patient was treated daily with 200 mg of itraconazole in combination with topical antifungals, achieving clinical improvement and mycological recovery, which was confirmed upon follow-up 1 month later. This is the first case report of atrophying pityriasis versicolor in Korea. It needs to be differentiated from other atrophying disorders of the skin. (Ann Dermatol 22(4) 456~459, 2010)
Background: Lipid peroxide (LPO) in comedones, which are produced as a result of sebum oxidation, might potentially induce interleukin-1α (IL-1α) and exacerbate comedogenesis and inflammatory changes ...in comedones. Objective: To investigate the relationship of proinflammatory cytokines and LPO levels in the extracts of comedones with the acne of clinical difference between smokers and non-smokers, and with the severity and distribution of the acne lesions. Methods: Twenty-two non-smoking and 21 smoking adult acne patients were evaluated by comedone extraction and measurement of proinflammatory cytokines and LPO levels. Acne severity and distribution of the lesions were also analyzed. Results: Relative to the non-smoking group, smokers had significantly higher levels of IL-1α and LPO in comedones. Their levels showed a positive correlation. However, there were no statistically significant difference between the severity or distribution of the disease and the levels of LPO and IL-1α in comedones. Conclusion: Smoking may be involved in the pathogenesis of adult acne by increasing the oxidative stress that results in subsequent accumulation of LPO in comedones. (Ann Dermatol 26(1) 11∼ 16, 2014)
Nitric oxide (NO) and heme oxygenase-1 (HO-1) play important roles in the regulation of stem cell proliferation and differentiation. However, it has not been examined whether human periodontal ...ligament (PDL) cells can differentiate into osteoblast-like cells by NO activity mediated via HO-1. The objective of this study was to determine the effect of NO on proliferation and differentiation in human PDL cells, and to identify the underlying mechanism of its actions. Primary human PDL cells were cultured with NO donor sodium nitroprusside (SNP); cell proliferation and differentiation were measured. NO production, cell viability and cell proliferation were evaluated using the Griess reagent, MTT assay and BrdU incorporation, respectively. To analyze differentiation, we measured alkaline phosphatase (ALP) activity, osteocalcin (OC), osteonectin (ON) expression, and bone sialoprotein (BSP) by Western blotting. SNP-induced NO production is associated with inducible nitric oxide synthase induction in a time and dose-dependent manner. SNP resulted in decreased cell proliferation and increased expression of osteogenic differentiation markers such as ALP, OC, ON and BSP. Maximal HO-1 was reached with 0.05mM SNP and gradually decreased with 1.0mM. Treatment with an HO-1 inhibitor and selective inhibitors of extracellular regulated kinase 1/2 and nuclear factor-kappaB blocked the SNP-induced growth inhibition, as well as osteoblastic differentiation. These data suggest that NO-induced osteogenic differentiation through HO-1 may be an important mediator of periodontal regeneration or bone tissue engineering.
