Implementation of Instrument Based on Eight Health Related Quality of Life Domains for Measuring of Willingness to Pay for Psoriasis Treatment

Abstract

Background: Psoriasis vulgaris (PsV) is a chronic skin condition that has a major impact on health-related quality of life (HRQOL).

Aim: To determine the individual burden of PsV on HRQOL using willingness to pay (WTP) instrument.

Materials and methods: Fifty-one consecutive PsV patients were asked to evaluate their overall health and psoriasis affected health by visual analogue scale (VAS), and interviewed on 8 domains (physical, emotional, sleep, work, social, self-care, intimacy, and concentration) of HRQOL and WTP for a hypothetical cure in each domain. Two additional questions proposing 6 alternatives for therapy were also asked. The analysis is performed with descriptive and frequency statistics, Mann-Whitney and Kruskal-Wallis tests.

Results: The domains ranked highly were: physical comfort (90%), social comfort (77%), emotional health (75%) and work (53%). The following tendencies concerning WTP for top four impacted domains were found: the median WTP were the highest in the top impacted domains; the younger patients were willing to pay more than the older ones; the highest median WTP amounts appear in the lowest income group; the highest median WTP is associated with smaller psoriasis affected health VAS scores. The largest proportion and number of patients (37.3%, n=19) stated preferences for the systemic therapy. The second preferred choice was the thalassotherapy (29.4%, n=15).

Conclusions: The utility and reliability of the instrument based on the assessment of WTP stated preferences for 8 domains of HRQOL for evaluation the individual burden of psoriasis were strongly supported.

Cardiac Glycoside Plants Self-Poisoning

Summary

Cardiac glycosides are found in a diverse group of plants including Digitalis purpurea and Digitalis lanata (foxgloves), Nerium oleander, Convallaria majalis (lily of the valley), Strophanthus gratus, etc. Nerium Oleander is an indoor and ornamental plant of an evergreen shrub. It’s widespread in countries with a Mediterranean climate. Oleander is one of the most poisonous plants known to humans. All parts of the nerium oleander are poisonous, primarily due to the contained cardiac glycosides - oleandrin, nerin, digitoxigenin, and olinerin of which oleandrin is the principal toxin. The bark contains the toxic substances of rosagenin which causes strychnine-like effects. Signs of poisoning appear a few hours after the adoption of the parts of the plant. Two cases of Nerium Oleander poisoning were presented. Clinical picture included gastrointestinal, cardiovascular and central nervous system effects. The clinical symptoms were characterized by nausea, vomiting, salivation, colic, diarrhoea, ventricular tachycardia, dysrhythmia, heart block, ataxia, drowsiness, muscular tremor. Treatment included administration of activated charcoal, symptomatic and supportive care.

Aggressive juvenile mandibular fibromatosis

ABSTRACT

Aggressive juvenile fibromatosis of the jawbones is a rare tumor presenting as infiltrative mass with unpredictable evolution. We report herein a 17-year-old student with a 6-month history of radiologically proven resorption of a part of the mandible, lingual displacement of tooth 34 and malocclusion. Alveolar ridge resorption and three dark-brown foci in the bone were seen after the tooth was extracted. Histological study showed the tumor tissue to have a bundle-like structure; immunohistochemically it was positive for vimentin, smooth muscle actin, β-catenin, Ki-67 (5%), and negative for desmin and cytokeratin 34bE12. The golden standard in the diagnostics of desmoid fibromatoses is the nuclear or membrane expression of β-catenin, which is found in 90% of the cases. Differential diagnosis include mandibular fibroma, well-differentiated fibrosarcoma, fibrosing histiocytoma, and infiltration from adjacent soft-tissue tumor. Aggressive juvenile fibromatosis should be managed by radical excision. Local recurrences are not rare, but metastases do not develop. In rare cases this type of fibromatosis has been known to regress spontaneously. Aggressive fibromatosis is a diagnostic challenge, since it remains in the grey zone between benign and malignant lesions of the oral cavity.

Quality of Sexual Life after Microsurgical Penile Denervation in Men with Primary Premature Ejaculation

Summary

Premature ejaculation (PE) is the most common sexual dysfunction in men, yet it is not well studied. Its frequency reaches 30% for men from 18 to 59 years of age in different countries. The aim of this article was to investigate the quality of sexual life in men with primary PE operated on with microsurgical penile denervation, using the Brief Male Sexual Functional Inventory (BMSFI). From September 2011 to March 2014, 22 patients were operated on with microsurgical penile denervation in the urology clinic of the University Hospital - Pleven and the Department of Urology at UMHAT Ruse AD. The mean result from the BMSFI in patients was 22 points preoperatively, indicating significant worsening of sexual function and quality of life in all five questionnaire domains. After surgery, the results increased to 28, 33 and 39 respectively, at 3, 6 and 12 months, respectively. Premature ejaculation not only leads to problems in controlling ejaculation but also worsens the overall sexual function and quality of life of patients.

Preoperative Evaluation of Sexual Function in Patients Undergoing Bilateral Nerve-Sparing Radical Retropubic Prostatectomy

Summary

During the last few years, prostate cancer is more frequently diagnosed in young patients. This lays emphasis on the necessity to preoperatively evaluate the sexual function in patients undergoing bilateral nerve sparing radical retropubic prostatectomy (BNSRRP). The aim of our study was to make an objective evaluation of the basic sexual function in patients with clinically localized prostate cancer and candidates for BNSRRP, using internationally validated questionnaires. We also tried to find a correlation between these questionnaires and the individual assessment of candidates, on one hand, and between comorbidities of the patients and degree of erectile dysfunction (ED), on the other hand. From January 2014 to March 2017, at the urology clinic of University Hospital – Pleven, 64 patients opted BNSRRP and reported to have preserved erectile function (EF), wishing to maintain this function after surgery. The patients’ histories and comorbidities were recorded on the day of hospitalization. The subjective assessment of the patients’ potency was compared with International Index of Erectile Function (IIEF). According to the EF domain of the IIEF, baseline EF was assessed in 28 patients. Twelve patients had mild ED, 9 patients had mild to moderate ED, seven patients had moderate, and eight had severe ED. The results showed that a significant number of patients with clinically localized prostate cancer who were candidates for BNSRRP reported to be fully potent but actually had impaired EF preoperatively. There was also a pronounced correlation between concomitant diseases and EF.

Low-Intensity Extracorporeal Shockwave Therapy – A New Approach in the Treatment of Erectile Dysfunction after Radical Prostatectomy

Summary

The experience accumulated with low-intensity extracorporeal shock wave therapy (LI-ESWT) from international clinical trials has demonstrated its safety, efficacy and good tolerance in treatment of erectile dysfunction (ED). The aim of this retrospective study was to investigate the effect of LI-ESWT in patients with ED after bilateral nerve sparing radical surgery for prostate cancer. Twenty-seven patients underwent bilateral nerve sparing radical retropubic prostatectomy (BNSRRP) at the clinic of urology of the university hospital in Pleven between January 2016 and December 2016. Twenty-one of these patients had pre-operative preserved erectile function (EF), as reported according to the International Index of Erectile Function (IIEF-5). Postoperatively, these 21 patients experienced a mild (18-21 points) impairment of EF. In 10 patients (group 1), LI-ESWT was performed. The procedure was performed once a week for 6 weeks with a LI-ESWT (BTL 6000 SWT Topline) instrument. The reading was obtained with IIEF-5 on the third and sixth month after the end of therapy. The other 11 patients (group 2) were used as a control group and did not receive treatment. In 5 patients in group 1, a recovery of EF (> 21 points) as per IIEF-5 was recorded at the third month after treatment. In two patients, the same score was recorded at the sixth month. No improvement was seen in three men in group 1. In the controls (group 2), a spontaneous EF improvement in four patients at sixth month was registered. Despite the small number of patients and their short-term follow-up, our initial results indicate that LI-ESWT is effective, safe and well-tolerated. It could be an alternative for early penis rehabilitation in patients who have undergone BNSRRP.

Original Article. Urinary Tract Desobstruction in Patients with Malignant Neoplasms of the Uterine Cervix

Summary

Cancer of the cervix causes internal, external compression or both of the upper urinary tract in 50-60%of patients in advanced stages. Retrograde stenting is the most widely used technique for desobstruction of the upper urinary tract in urology practice. Diversion of urine flow is an alternative, achieved by nephrostomy of one or both kidneys.We studied retrospectively 33 women with upper urinary tract obstruction caused by carcinoma of the uterine cervix operated on between March 2014 and March 2015 in the urology clinic at the University Hospital in Pleven, Bulgaria. Apercutaneous nephrostomy (PNS) was placed in 17 patients, and 11 patients hadaretrograde catheterization with ureteral stent type JJ. Five patients were treated with both methods. Placement ofa JJstent was the first choice procedure for all patients since it providesabetter quality of life. PNSimproves renal function faster than retrograde JJstenting. Therefore, the first method of choice for patients with an untreated primary cervical, uterine cancer is the placement of PNS. Retrograde JJstenting is the method of choice in patients who undergo surgery and radiation therapy withoutarelapse of the disease.

Original Article. Open Retropubic and Robot-Assisted Radical Prostatectomy in Prostate Carcinoma: Advantages of Methods

Summary

Prostate cancer (PC) is the most common type of cancer in men inanumber of countries. The choice of surgical technique for radical prostatectomy (RP) concerns both patients and urologists. The choice is not easy to make, since data is still limited due to the lack of large multicentric randomized research trials. For three years (2011-2014), 244 patients with limited prostate cancer were operated in the Urology Clinic of the University Hospital in Pleven. Robot-assisted radical prostatectomy (RARP) was performed on 35 patients (14%), open retropubic radical prostatectomy (ORP) - on 199 patients (81%), and laparoscopic RP - on 12 patients (5%). The preoperative and post-op results from the first two groups were compared. For the follow-up period of 12 months, functional results in 82 patients of the ORPgroup were compared to the results in the 35 patients of the RARPgroup. The operative time was significantly longer in the RARPgroup, and blood loss was lower. The catheter stay was shorter in patients with RARP. The percentage of significant postoperative complications was 0%in the patients with RARPand 3%in the patients with an ORP. RARPpatients demonstrated better continence: 91%vs. 87%and erectile function46%vs.40%at 12 months.
