Globozoospermia is a rare type of teratozoospermia. It occurs in 0.1% of all andrological patient's and used to be considered sterile. Globozoospermic patient has 100% round headed spermatozoa, but the spermiogram is normal. The spermatozoa show oval-shape head, the lack of a nuclear envelope, acrosome, and post acrosomal sheath. OBJECTIVE: To report that a couple with infertility secondary to globozoospermia received ICSI treatment. MATERIAL AND METHOD: Case report. RESULTS: In the first trial, fertilization was failed. In the second trial, 40% of oocytes were fertilized and all of these embryos were cleaved, but pregnancy did not achieved. In the third trial, sperm injected oocytes were exposed to 10 micrometer calcium ionophore for 15 min. All of the injected oocytes were fertilized and proceeded to develop. Triplet pregnancy was achieved after the transfer of six embryos in their third cycle. One embryo vanished and the remaining twins (female) were delivered at 33 weeks of gestation by Caesarean section. CONCLUSION: This result shows that assisted activation following ICSI may overcome infertility associated with globozoospermia.

PURPOSE: To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer. MATERIALS AND METHODS: Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the in-house self respiration monitoring (SRM) system was used for visual feedback. For each scan, treatment plans were generated and dosimetric parameters from DIBH and EIBH plans were compared to those of FB plans. RESULTS: All patients completed CT scans with different breathing maneuvers. When compared with FB plans, DIBH plans demonstrated significant reductions in irradiated heart volume and the heart V25, with the relative reduction of 71% and 70%, respectively (p < 0.001). EIBH plans also resulted in significantly smaller irradiated heart volume and lower heart V25 than FB plans, with the relative reduction of 39% and 37%, respectively (p = 0.002). Despite of significant expansion of lung volume using inspiration breath-hold, there were no significant differences in left lung V25 among the three plans. CONCLUSION: In comparison with FB, both DIBH and EIBH plans demonstrated a significant reduction of radiation dose to the heart. In the training course, SRM system was useful and effective in terms of positional reproducibility and patient compliance.

PURPOSE: This study examined self-efficacy, self-care behavior, posttraumatic growth, and quality of life in cancer patients and their levels by disease characteristics groups to identify patient groups that require psychosocial intervention. METHODS: We surveyed 107 patients using a structured questionnaire about the four factors and analyzed the factors by stratifying the patients by the period after the cancer diagnosis, by stage and by current treatment status. RESULTS: The mean score for self-efficacy was 37.78, and that for self-care behavior 49.96. Patients who were diagnosed less than one year ago scored higher on medication, a sub-category of self-care behavior, than the post-diagnosis period of 1~2 year group. The score was higher in the currently-treated group than the follow-up and distant metastasis groups. For posttraumatic growth, the mean was 56.17, and the factor was higher in the 1~2 year post-diagnosis group after than the less than one year group. The score was higher in the follow-up group than the currently-treated group. With regard to quality of life, the mean score was 25.79, and no significant correlation was found with disease characteristics. CONCLUSION: A shorter post-diagnosis period increased self-care behavior, and the greatest posttraumatic growth was reported by the 1~2 year post-diagnosis group. It may be necessary to provide cancer patients with an education program and other strategies less than one year after the diagnosis to improve self-efficacy and self-care behavior. To promote post-traumatic growth, it may be helpful to provide patients with psychosocial intervention within two years after the diagnosis.

Hypertension is the leading factor of cardiovascular mortality and morbidity. Although antihypertensive medical treatment is the cornerstone of blood pressure control, lifestyle modification, including optimal diet therapy, such as dietary approaches to stop hypertension (DASH), cannot be overemphasized.Current Concepts: Due to the mismatch between sodium intake and excretion process being the key mechanisms according to physiologic principles, low sodium and high potassium intakes are the critical components of DASH. If the patient has a sensitive elevation of blood pressure following increased sodium intake, a low sodium diet could be essential for optimal blood pressure control. Salt sensitivity is increased by the activated reninangiotensin system, sympathetic nervous activity, sodium channels disorder, and endothelial dysfunction and frequently observed in the elderly and patients with obesity and chronic kidney disease. Increased potassium intake could attenuate sodium absorption by affecting the intracellular chloride and WNK4 activity, especially in patients with salt sensitivity or high salt intake.Discussion and Conclusion: For low sodium and high potassium intakes, the Na/K diet ratio could be a good target for intervention, and this approach is a critical component of DASH.

Background: Both allogenous fibular bone graft and minimally invasive plate osteosynthesis have been developed to reduce issues such as fixation failure, displacement, angulation, and nonunion after plate fixation of proximal humeral fractures. However, there have been no studies investigating the differences in clinical results between these methods. The purpose of this study was to investigate the clinical differences between open reduction and plate fixation via a deltopectoral approach with allogenous fibular bone graft and a minimally invasive approach, in Neer's classification two-, three-part proximal humeral fractures. Methods: In this retrospective study, 77 patients with Neer classification two-, three-part proximal humeral fractures were treated at two different institutions. Clinical and radiological evaluations were performed in 39 patients who underwent minimally invasive plate osteosynthesis at one institution (group A) and 38 patients who underwent the deltopectoral approach with allogenous fibular bone graft at another institution (group B). The results between the groups were compared. Results: The minimally invasive plate osteosynthesis procedure (group A) was significantly less time- consuming and caused less bleeding than allogenous fibular bone graft through a deltopectoral approach (group B) (P<0.05). The duration of the fracture union was significantly reduced in group A (14.5±3.4 weeks; range, 10–22 weeks) compared to group B (16.4±4.3 weeks; range, 12–28 weeks) (P<0.05). There were no statistically significant differences between the two groups when evaluating the visual analog scale and Constant scores 1 year postoperatively. Radiological evaluation including neck-shaft angle and plate height were measured on the final follow-up X-ray image. There was no difference in radiological outcomes between the two groups. There were no statistically significant differences in malunion between the two groups; there were three malunion cases (7.7%) in group A and four (10.5%) in group B. Conclusions The minimally invasive plate osteosynthesis procedure and deltopectoral approach with allogenous fibula bone graft for Neer's classification two-, three-part proximal humeral fractures demonstrated similar clinical and radiological results. However, allogenous fibula grafts require longer surgery, cause more bleeding, and result in longer fracture healing time than the minimally invasive plate osteosynthesis procedure.

PURPOSE: To determine feasibility of RapidArc in sequential or simultaneous integrated tumor boost in whole brain radiation therapy (WBRT) for poor prognostic patients with four or more brain metastases. MATERIALS AND METHODS: Nine patients with multiple (> or =4) brain metastases were analyzed. Three patients were classified as class II in recursive partitioning analysis and 6 were class III. The class III patients presented with hemiparesis, cognitive deficit, or apraxia. The ratio of tumor to whole brain volume was 0.8-7.9%. Six patients received 2-dimensional bilateral WBRT, (30 Gy/10-12 fractions), followed by sequential RapidArc tumor boost (15-30 Gy/4-10 fractions). Three patients received RapidArc WBRT with simultaneous integrated boost to tumors (48-50 Gy) in 10-20 fractions. RESULTS: The median biologically effective dose to metastatic tumors was 68.1 Gy10 and 67.2 Gy10 and the median brain volume irradiated more than 100 Gy3 were 1.9% (24 cm3) and 0.8% (13 cm3) for each group. With less than 3 minutes of treatment time, RapidArc was easily applied to the patients with poor performance status. The follow-up period was 0.3-16.5 months. Tumor responses among the 6 patients who underwent follow-up magnetic resonance imaging were partial and stable in 3 and 3, respectively. Overall survival at 6 and 12 months were 66.7% and 41.7%, respectively. The local progression-free survival at 6 and 12 months were 100% and 62.5%, respectively. CONCLUSION: RapidArc as a component in whole brain radiation therapy for poor prognostic, multiple brain metastases is an effective and safe modality with easy application.

PURPOSE: To identify the structural integrity of the healing site after medial open wedge high tibial osteotomy (MOWHTO) in patients with a posterior root tear of the medial meniscus (PRTMM) and chondral lesion by second-look arthroscopy and to determine the clinical and radiological findings. MATERIALS AND METHODS: From August 2010 to June 2016, 52 consecutive patients underwent MOWHTO and arthroscopic examination without a chondral resurfacing procedure and meniscal treatment for PRTMM. Twenty-four patients were available for second-look arthroscopic evaluation. The mean follow-up period was 19.5 months (range, 5 to 46 months). Clinical evaluation was based on the Lysholm knee scores and Hospital for Special Surgery (HSS) scores. RESULTS: There were 5 lax healing, 6 scar tissue, 13 failed healing of PRTMM. Definite change of chondral lesion was not observed. The Kellgren-Lawrence grade did not improve according to the follow-up plain radiograph. The mean Lysholm score improved from 34.7 preoperatively to 77.1 at the last follow-up, and the mean HSS score significantly increased from 36.5 to 82.4. CONCLUSIONS: This study revealed a low rate of healing potency of PRTMM and chondral lesion after MOWHTO without any attempt for meniscal treatment or chondral resurfacing. The cartilage and healing status of PRTMM was not associated with improved clinical outcomes and radiological findings.

PURPOSE: To report a case of chemical injury of the cornea caused by high-dose ethanol during orbital wall fracture repair. CASE SUMMARY: A 56-year-old male presented with pain after blowout fracture repair surgery. During the surgery, 2% hexethanol solution (2% chlorhexidine and 72% ethanol mixture), which was used for disinfection of the face, flowed into the left eye. Conjunctival injection in the left limbus, a large corneal epithelial defect, and severe stromal edema were subsequently observed. The patient was treated with topical antibiotics, steroids, and autologous serum eye drops. After 1 week, the corneal epithelial defect was improved, but at the second month of therapy, recurrent corneal erosion with deterioration of the endothelial cell function occurred. Anterior stromal puncture and laser keratectomy were performed. The corneal epithelial defect and erosion improved, but the endothelial cell density was severely decreased. CONCLUSIONS: The 2% hexethanol solution is usually used for preoperative skin disinfection, but it contains a high concentration of ethanol. The surgeon should be aware that high concentrations of ethanol may result in severe corneal damage, including corneal endothelial dysfunction and limbal cell deficiency.

Caffeic acid (CA) is a phenolic compound found naturally in plants and foods. CA and its natural derivatives are reported to have anti-cancer effects on many cancers, including melanoma. (E)-N-(4-Butylphenyl)-3-(3,4-dihydroxyphenyl)acrylamide (4-BPCA) is an amide derivative of CA. Thus far, the anti-cancer effect and mechanism of 4-BPCA in melanoma cells remain unknown. Here we investigated whether 4-BPCA inhibits the growth of B16F10 cells, a mouse melanoma cell line. Of note, treatment of 4-BPCA at 5 M for 24 or 48 h significantly reduced the growth (survival) of B16F10 cells. On mechanistic levels, treatment with 4-BPCA for 24 h led to the activation of caspase-9/3, but not caspase-8, in B16F10 cells. 4-BPCA treatment for 2 or 4 h also decreased the expression levels of myeloid B-cell lymphoma 1 (Mcl-1) in B16F10 cells. However, 4-BPCA treatment for the times tested did not influence the expression levels of X-linked inhibitor of apoptosis protein (XIAP) in B16F10 cells. Of interest, treatment of 4-BPCA for 2 or 4 h greatly reduced the phosphorylation levels of JAK-2 and STAT-5 without altering their total protein expression levels. 4-BPCA also had abilities to increase the expression and phosphorylation levels of glucose-regulated protein-78 (GRP-78) and eukaryotic translation initiation factor-2α (eIF-2α) in B16F10 cells. In summary, these results demonstrate firstly that 4-BPCA has a strong growth-inhibitory effect on B16F10 melanoma cells, mediated via activation of the intrinsic caspase pathway, inhibition of JAK-2 and STAT-5, and triggering endoplasmic reticulum (ER) stress.
