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.

Sleep apnea syndrome (SAS) has known to be associated with obesity, hypoxemia, sympathetic activation, and hypertension. In addition, SAS is associated with various mechanisms involved in cardiovascular diseases, such as oxidative stress, dyslipidemia, smoking, and psychological stress. In recent prospective observation studies, SAS is known to be a risk factor for cardiovascular diseases, i.e., heart failure, stroke, and coronary artery diseases. The association with heart failure was most evident. In some participants in the longitudinal study applied with continuous positive airway pressure (CPAP) treatment, SAS was not associated with prognosis. With the viewpoints in the current standard of cardiovascular medicine, there seems to be few evidence showing that CPAP treatment could prevent or improve cardiovascular outcome. Detailed review of the limitations of the prospective observational studies suggests that more sophisticated measurement of the clinical outcomes and adjustment of confounding factors will be required in the future studies. And for the clinical application, more evidence of CPAP treatment on the cardiovascular outcomes are mandatory.

Although it is difficult to find a cause of chronic urticaria in children, previous studies have been identified some triggers, such as autoimmunity, physical stimuli, food and its additives, and infection. History taking and physical examination remain the best tool for identifying an underlying cause of urticaria. First investigations include a complete blood count with differential, erythrocyte sedimentation rate, and C-reactive protein in children with chronic urticaria. If physical stimuli are suspected as triggers of chronic urticaria, appropriate provocation tests can be performed. Although the frequency of autoimmune urticaria was relatively high compared to the other causes in children with chronic urticaria, it is not easy to apply routine use of autologous serum skin tests to clinical practice. Additional extensive laboratory investigations are not required in the majority of cases. Second-generation H1-antihistamines are the mainstay of treatment from current guidelines in children with chronic urticaria, and dosage can be increased if the standard dose is not effective. Data on chronic urticaria in children are scarce, and causes have been considered to be similar to those in adults. Therefore, diagnostic approaches and treatment principles of chronic urticaria in children have been derived from extrapolating data in adults. In the future, comparative studies for the causes of chronic urticaria between children and adults, and therapeutic modalities for refractory cases will be needed.

The marginal integrity of the crown can be broken during endodontic access cavity preparation due to the vibration of burs. Therefore, the purpose of this study was to evaluate the effect of endodontic access cavity preparation on the marginal leakage of full veneer gold crowns. 24 intact molars were mounted in acrylic resin blocks and prepared for crowns by a restorative dentist and crowns were cast with gold alloy. 20 Crowns were cemented with glass ionomer cement and 2 crowns were not cemented for positive control. 200 thermo-cycles from 5degrees C to 50degrees C with a travel time of 20s were completed. Then samples were randomly divided into 2 experimental groups of 9 each. Endodontic access preparation and zinc-oxide eugenol temporary fillings were done in Group 1. Teeth in Group 2 were not treated. Samples were coated with 2 layers of nail varnish and were immersed in 1% methylene blue dye for 20 hrs. Endodontic access was prepared in 2 samples, which were coated with nail varnish on all surfaces for negative control. After washing in running water, gold crowns were cut with a #330 bur. Four buccolingual sections, 2 mm apart, were cut from the central section of each tooth and were examined and scored under the microscope for dye leakage. Score 1: leakage to the cervical 1/3 of the axial wall, Score 2: leakage to the middle 1/3 of the axial wall, Score 3: leakage to the coronal 1/3 of the axial wall, Score 4: leakage to the occlusal surface. The median value for Group 1 is 4 and for Group 2 is 2. The result of this study showed that samples in Group 1 leaked more than those in Group 2. This finding was significant(P<0.001).

In general, each increase of 20/10 mmHg (systolic to diastolic) blood pressure (BP) above 115 mmHg and 75 mmHg results in a two-fold increased risk for cardiovascular complications. In addition, cerebrovascular events in association with hypertension are more frequent than myocardial infarctions in Asian populations. To prove the correlation between cardiovascular events and hypertension observed in the observational studies, BP-lowering studies should be performed to demonstrate the preventive effect on cardiovascular events. However, no randomized clinical studies to date have been able to prove the preventative effects of BP lowering in the blood pressure around 140/90 mmHg or mild hypertension. Despite the fact that many guidelines, including Joint National Committee-7 guidelines, recommend BP lowering for those ranges of blood pressure. In recent years, there have been many contradictory hypotheses about the asymmetry between the results from observational studies and clinical trials, which have led to the establishment of representative studies to set new target BPs. Such studies have proven the benefits of BP lowering closer to optimal blood pressure. Therefore, a discussion about applying these findings to patient care is needed.
