Effect of varying core thicknesses and artificial aging on the color difference of different all-ceramic materials.

Objective: Clinicians should reserve all-ceramics with high translucency for clinical applications in which high-level esthetics are required. Furthermore, it is unclear whether a correlation exists between core thickness and color change. The aim of this study was to examine the effects of different core thicknesses and artificial aging on the color stability of three all-ceramic systems.

Effect of systemic administered zoledronic acid on osseointegration of a titanium implant in ovariectomized rats.

Objective: The aim of this study was to evaluate whether zoledronic acid improves post-implant osseointegration in an ovariectomized rat model.

Materials And Methods: A total of 36 female Wistar rats were subdivided into three groups: control (CTRL), ovariectomized (OVX) and ovariectomized + zoledronic acid (OVX/ZOL). Both OVX and OVX/ZOL groups underwent ovariectomy procedures, while the CTRL group received a sham operation.

Does circumcision have a relationship with ejaculation time? Premature ejaculation evaluated using new diagnostic tools.

The aim of the study is to investigate whether there is an effect of adult circumcision on ejaculation parameters and to research the relationship between intravaginal ejaculation latency time (IELT) and premature ejaculation diagnostic tool (PEDT). Adults who underwent voluntary circumcision between September 2010 and November 2011 were enrolled in this prospective study. The IELT before and 3 months following circumcision was recorded.

Effective penile block for circumcision in adults.

Background: The dorsal nerve block of the penis during circumcision has not been standardized and the effectiveness of the block can be changeable. The aim of this study was to determine which technique is more suitable for blocking sensory innervations of penis.

Methods: This prospective study was done on adults who voluntarily applied to be circumcised.

Local or spinal anesthesia in subinguinal varicocelectomy: a prospective randomized trial.

Objective: To determine whether local anesthesia (LA) is an acceptable alternative to spinal anesthesia (SA) for varicocelectomy.

Methods: A total of 60 men with varicocele were included in the present study. The evaluation of pain during and after surgery was determined using the visual analog scale.

Free nerve ending density on skin extracted by circumcision and its relation to premature ejaculation.

Many studies have shown that skin tissue extracted by circumcision can cause differences in sexual function, especially at the time of ejaculation. Sensitivity changes in penile skin and sexual satisfaction deriving from circumcision starting from premature ejaculation (PE) are discussed. Furthermore, most of these studies rely on questionnaires.

Myositis ossificans around shoulder following military training programme.

The myositis ossificans around shoulder in military recruits are not reported yet. Three young male soldiers presented with complaints of palpable mass at the anterior aspect of shoulder; tenderness around the superior part of deltopectoral groove close to acromioclavicular joint; and restriction of shoulder motion. They also noticed ecchymosis and pain around the coracoid process and anterior shoulder region during regular firing exercises.

Repair of long bone defects with demineralized bone matrix and autogenous bone composite.

Background: Repair of diaphyseal bone defects is a challenging problem for orthopedic surgeons. In large bone defects the quantity of harvested autogenous bone may not be sufficient to fill the gap and then the use of synthetic or allogenic grafts along with autogenous bone becomes mandatory to achieve compact filling. Finding the optimal graft mixture for treatment of large diaphyseal defects is an important goal in contemporary orthopedics and this was the main focus of this study.

The effect of obesity on the assessment of diabetic peripheral neuropathy: a comparison of Michigan patient version test and Michigan physical assessment.

Objective: Nerve conduction studies (NCS) and Michigan Neuropathy Screening Instrument (MNSI) are commonly used to make the diagnosis of diabetic peripheral neuropathy. The objective of this study was to compare the diagnostic values of MNSI patient version test and physical test for the assessment of the diabetic peripheral neuropathy in obese vs. non-obese patients.

Saving the zone of stasis: is glutathione effective?

One of the main subjects that burn researches are focused on is saving the zone of stasis. There are many molecules that are used for this purpose, but all have their drawbacks. Glutathione is one of the major buffer molecules of the cells and is known to increase the thermo-resistance of the cells.

Results of artificial inflammation in scarless foetal wound healing: an experimental study in foetal lambs.

Recent experimental and clinical evidence suggests that the foetus responds to injury in a fashion fundamentally different from the adult. Foetal wound healing occurs without scar formation. The mechanisms causing this difference are still not well defined but absence of inflammation may play a significant role.
