Low ejection fraction and apical akinesia were completely resolved after her symptoms got improved.

Left main and two vessels calcified coronary aneurysms presented as out of hospital cardiac arrest in young patient.

A 37-year-old patient was admitted secondary to ventricular fibrillation induced out of hospital cardiac arrest. Coronary angiogram revealed left main, left anterior descending, and right coronary arteries aneurysms. The patient underwent bypass surgery with four grafts.

Mobile Application for Ulcer Detection.

Purpose: The number of patients who are suffering from diabetes nowadays is increasing significantly. In some countries, the percentage of population who suffer from this disease can reach up to 20%. Diabetic patients have to deal with their medical conditions and any further complications that this disease may cause.

Safety of Intracavernous Bone Marrow-Mononuclear Cells for Postradical Prostatectomy Erectile Dysfunction: An Open Dose-Escalation Pilot Study.

Unlabelled: Evidence from animal models replicating postradical prostatectomy erectile dysfunction (pRP-ED) suggests intracavernous injection of bone marrow-mononuclear cells (BM-MNCs) as a promising treatment approach for pRP-ED. We conducted a phase 1/2 pilot clinical trial of intracavernous autologous BM-MNC injection to treat pRP-ED (NCT01089387). Twelve patients with localized prostate cancer and vasculogenic pRP-ED refractory to maximal medical treatment were divided into four equal groups treated with escalating BM-MNC doses (2×10(7), 2×10(8), 1×10(9), 2×10(9)).

[Azoospermia and a history of inguinal hernia repair in adult].

Background: Inguinal hernia repair is one of the most performed surgeries in the world. It is recognized that any surgery of the pelvic floor may represent a risk factor of male infertility.

Method: Retrospective study of patients with azoospermia and a history of adult inguinal hernia repair surgery and referred to our center between January 1990 and January 2011 for infertility.

Polytetrafluoroethylene expanded prosthesis as replacement of the inferior vena cava in renal cell carcinoma with caval thrombus.

Objective: To assess the outcomes of inferior vena cava replacement with polytetrafluoroethylene expanded prosthesis in patients with renal cell carcinoma and caval thrombosis.

Methods: All patients who underwent radical nephrectomy with inferior vena cava replacement by polytetrafluoroethylene expanded prosthesis for renal cancer associated with inferior vena cava thrombosis and a suspicion of inferior vena cava wall invasion from January 2000 to June 2011 were considered for this study. Demographic data, postoperative course, graft patency and survival data were evaluated.

[Evaluation of a nurse educational program for intracavernous alprostadil injections after radical prostatectomy].

Objectives: To evaluate a nurse educational program for penile rehabilitation after radical prostatectomy (RP) based on intracavernous alprostadil injection (IAI).

Patients: One hundred consecutive patients started IAI one month after RP under the supervision of a nurse practitioner (day 0). Patients performed the first injection (2.

[Management of erectile dysfunction by general practitioners and endocrinologists in diabetes: a survey of 130 patients].

Objectives: To assess the prevalence, the severity and expectations regarding erectile dysfunction (ED) in diabetic patients, then to investigate how general practitioners (GP) and endocrinologists manage this disorder.

Patients And Methods: A questionnaire was given during 5 weeks to every diabetic patient addressed to the endocrinology department in order to assess erectile function (IIEF5), patient's bother and expectations to be treated, and the management of ED by GP and endocrinologists and differences in management between male and female doctors.

Results: One hundred and thirty questionnaires were available.

[Results of laparoscopic nephroureterectomy for transitional cell carcinoma].

Objective: To report our experience of laparoscopic nephroureterectomy and to compare our results to those published in the literature.

Patients And Method: Between 1997 and 2005, 15 laparoscopic nephroureterectomies were performed by 2 surgeons, in 12 men and 3 women for upper urinary tract transitional cell carcinoma. The mean age of the patients was 66 years.

Optimisation of the composition of a screen-printed acrylate polymer enzyme layer with respect to an improved selectivity and stability of enzyme electrodes.

Glucose oxidase (GOD) was immobilized on screen-printed platinum electrodes by entrapment in a screen printable paste polymerized by irradiation with UV-light. The influences of different additives, in particular polymers and graphite, on the sensitivity and stability of the sensor and the permeability of the enzyme layer for a possible electrochemical interferent were investigated. The chosen additives were Gafquat 755N, poly-L-lysine, bovine serum albumin (BSA), sodium dodecylsulfate (SDS), polyethylene glycol (PEG), Nafion and graphite.

Cathodic stripping voltammetry of the anticancer agent 5-fluorouracil and determination in urine.

Cathodic stripping voltammetry was used to determine 5-fluorouracil (5-FU) in the presence of traces of Cu(II). It was found that the addition of 5 x 10(-9) mol dm(-3) Cu(II) to the measurement cell greatly enhanced the peak current of the adsorbed molecule. Different parameters were tested to optimize the conditions for the determination of 5-FU.

Determination of Ag(I) with chemically modified carbon paste electrode based on 2,3-dicyano 1,4-naphthoquinone.

The utility of carbon paste modified with 2,3-dicyano 1,4-naphthoquinone (CYNQ) for the voltammetric determination of Ag(I) is demonstrated. The method is based on the formation of Ag(I) complex with CYNQ by accumulation from the aqueous solution to the electrode surface without an applied potential. Using the medium exchange technique, the electrode was transferred to another media followed by linear-scan voltammetric measurements.
