Plasma homocysteine levels in polycystic ovary syndrome and congenital adrenal hyperplasia

The purpose of this study was to determine whether polycystic ovary syndrome (PCOS) and nonclassic 21-hydroxylase deficiency (CAH) are related to hyperhomocysteinemia, and to investigate if there is a correlation between homocysteine levels and insulin sensitivity in women with PCOS and CAH. Fifty patients with PCOS, 50 patients with CAH and 25 control women were included in the study. Blood samplings were performed in the early follicular phase for measuring hormone profile, Vitamin B(12), folate, homocysteine levels and fasting blood glucose. Ovulatory status was assessed with timed serum progesterone measurements. Homeostasis model assessment-insulin resistance (HOMA-IR) was calculated as a measure of insulin resistance. Mean homocysteine levels were found as (8.9 + 1.9 micromol/l and 17.7 + 3.6 micromol/l) in the normal group and PCOS respectively (p<0.001), but there was no statistical significance between nonclassic 21-hydroxylase deficiency (9.0 + 2.2 micromol/l) and control group. Most of the patients in PCOS group (35 of 50) were significantly insulin resistant. However, there was no insulin resistant patient in CAH or control group. When we compare the two subgroups of PCOS women, the patients with insulin resistance had significantly higher homocysteine levels than the ones who were not insulin resistant. There were positive correlations among serum homocysteine, insulin and androgen levels in PCOS patients. There were no correlations among these parameters in CAH and control groups. Increased homocysteine levels may contribute to increased cardiovascular disease risk in patients with PCOS. The reason for hyperhomocysteinemia seems to be related to insulin resistance but not high androgen levels.     

Decontamination Techniques of Pathogen Bacteria in Meat and Poultry

Means of controlling or even improving the safety of food products is to decontaminate the carcasses or products during or at the end of the production line. The decontamination of meat and poultry can help to reduce human foodborne infections. However, process hygiene to prevent contamination should never be neglected. Some techniques of decontaminating raw meat and poultry meat products are discussed in this review.     

Robot-Assisted Radical Prostatectomy After Previous Prostate Surgery

Background and Objectives:

Our objective is to clarify the effect of previous transurethral resection of the prostate (TURP) or open prostatectomy (OP) on surgical, oncological, and functional outcomes after robot-assisted radical prostatectomy (RARP).

Methods:

Between August 1, 2009, and March 31, 2013, 380 patients underwent RARP. Of these, 25 patients had undergone surgery for primary bladder outlet obstruction (TURP, 20 patients; OP, 5 patents) (group 1). A match-paired analysis was performed to identify 36 patients without a history of prostate surgery with equivalent clinicopathologic characteristics to serve as a control group (group 2). Patients followed up for 12 months were assessed.

Results:

Both groups were similar with respect to preoperative characteristics, as mean age, body mass index, median prostate-specific antigen, prostate volume, clinical stage, the biopsy Gleason score, D''Amico risk, the American Society of Anesthesiologists (ASA) classification score, the International Prostate Symptom Score, continence, and potency status. RARP resulted in longer console and anastomotic time, as well as higher blood loss compared with surgery-naive patients. We noted a greater rate of urinary leakage (pelvic drainage, >4 d) in group 1 (12% vs 2,8%). The anastomotic stricture rate was significantly higher in group 1 (16% vs 2.8%). No difference was found in the pathologic stage, positive surgical margin, and nerve-sparing procedure between the groups. Biochemical recurrence was observed in 12% (group 1) and 11.1% (group 2) of patients, respectively. No significant difference was found in the continence and potency rates.

Conclusions:

RARP after TURP or OP is a challenging but oncologically promising procedure with a longer console and anastomosis time, as well as higher blood loss and higher anastomotic stricture rate.     

Laparoscopic Radical Prostatectomy Alone or With Laparoscopic Herniorrhaphy

Background and Objectives:

Prostate cancer and inguinal hernia are common health issues in men aged more than 50 years. Recently, more data are accumulating that laparoscopic radical prostatectomy (LRP) and laparoscopic inguinal hernia repair (LIHR) can be performed in the same operation. The purpose of this study was to compare patients who underwent simultaneous extraperitoneal LRP (E-LRP) and LIHR with control patients who underwent only E-LRP in a matched-pairs design.

Methods:

Medical records of 215 patients were evaluated, and 20 patients who underwent E-LRP+LIHR were compared with 40 patients who underwent only E-LRP in a matched-pairs analysis. Preoperative clinical parameters (age, body mass index, prostate-specific antigen, clinical stage, Gleason score of the prostate biopsy, and prostate volume) and operative data (operation time, duration of catheterization, length of hospital stay, estimated blood loss, time to perform the anastomosis and its quality, and the percentage of patients with bilateral lymphadenectomy) were evaluated, as well as postoperative parameters (pathological stage, Gleason score, specimen weight, follow-up duration, biochemical recurrence, complication rates, and duration of postoperative analgesic treatment).

Results:

No statistically significant differences were found in the preoperative and operative parameters between the 2 study groups. Pathological parameters and the follow-up period and complication rates were similar between the 2 groups.

Conclusion:

Performing LIHR and E-LRP during the same operation is safe and feasible in the treatment of patients with prostate cancer and inguinal hernia.     

Treatment Outcomes of Long-Pulsed Nd: YAG Laser for Two Different Subtypes of Rosacea

Background: A variety of lasers have been used for the treatment of rosacea. However, treatment of this condition with long-pulsed neodymium-doped yttrium aluminium garnet laser has not been reported yet. Objective: To assess the efficacy and safety of long-pulsed neodymium-doped yttrium aluminium garnet laser in two different subtypes (erythematotelangiectatic and papulopustular) of rosacea. Methods: A total of 66 patients were enrolled in the study. All of the patients were treated with long-pulsed neodymium-doped yttrium aluminium garnet laser with 3- to 4-week intervals. Rosacea severity score was assessed by using photographs. Improvement in severity was defined as the percentage reduction in severity scores from baseline to the end of treatment. Patients were also asked about their own opinions of improvement at the end of the treatment. Side effects were also documented. Results: Good to excellent improvement was achieved in up to 50 percent of the patients in the erythematotelangiectatic and papulopustular groups. Percent improvement of global severity was significantly greater in the erythematotelangiectatic patients than in the papulopustular patients. The majority of patients from both groups noted a significant improvement of the lesions. Hypopigmented atrophic scars were seen in two patients. Conclusion: The long-pulsed neodymium-doped yttrium aluminium garnet laser is a safe and effective treatment for vascular and inflammatory lesions of rosacea.Rosacea is a chronic inflammatory cutaneous disorder with periods of exacerbations and remissions. Clinical findings are characterized by flushing, erythema, telangiectasia, papules, and pustules. There are four recognized subtypes—erythematotelangiectatic (ETR), papulopustular (PPR), phymatous, and ocular.1 Although angiogenic and sebaceous factors have been implicated in the etiopathology of the disease, it remains unclear. Vascular abnormalities, dermal matrix degeneration, environmental factors, and microorganisms may have a potential role in the development of rosacea.2Rosacea may significantly affect patients’ lives, leading to considerable psychological and social distress over appearance. Therefore, management of this condition is very important. There is no definite cure. Electrosurgery and lasers can be used to decrease vascular lesions.3 Topical and/or oral antibiotics can be used to suppress the inflammatory lesions. Although these methods are moderately successful in controlling symptoms, relapse usually occurs shortly after the cessation of therapy.4,5Many types of lasers and light devices have been increasingly used in the treatment of rosacea. However, the role of long-pulsed neodymium-doped yttrium aluminium garnet (Nd:YAG) laser in this condition has not been well-studied. In this study, the authors assessed the efficacy of long-pulsed Nd:YAG laser in treating patients with two different subtypes (ETR and PPR patients) of rosacea.
