Genital self-mutilation: A challenging pathology (Review).

Genital self-mutilation is a pathology that leads to numerous and important discussions, rarely presented in the medical literature. There have been many attempts to explain the reasons behind these medical phenomena, but single cases have been generally reported, making it extremely difficult to draw valid conclusions. It is acknowledged that there are psychotic and non-psychotic causes, from psychiatric problems and sexual identity disorders to cultural or religious reasons, alcohol or recreational drug consumption, unconventional types of sexual satisfaction or self-satisfaction. Recent theories consider self-mutilation as a phenomenon of reducing distress or tension, as an expression of feelings of anger or sorrow. It is believed that 55-85% of those who have resorted to self-mutilation have at least once in their life tried to commit suicide. There is evidence that early discovery and intervention as well as proper treatment in regards to psychosis can significantly reduce the number of self-mutilation episodes, with a protective role of these individuals. Cases of genital self-mutilation may be considered real medical emergencies, sometimes extremely challenging and accompanied by severe complications. Injury of the genital area is usually accompanied by numerous early or long-term complications due to the marked vascular area and to the microbial flora present in this part of the body. The degree of mutilation is an unforeseen aspect that the medical staff may have to encounter during the intervention, sometimes testing their imagination and surgical skills when dealing with such a case. Understanding the causes of these self-aggressive behaviors, which may be life-threatening, is critical and multidisciplinary mobilization is needed after treatment of the acute phases. The outcome of these patients depends on integrated collaborative work. These cases represent a serious reason for frustration for the physicians involved in solving them, and knowledge of these issues is valuable to urologists, psychiatrists and other health professionals.

Efficacy of instillation treatment with hyaluronic acid in relieving symptoms in patients with BPS/IC and uncomplicated recurrent urinary tract infections - Long-term results of a multicenter study.

The purpose of this study is to evaluate the efficacy of intra-vesical instillations with hyaluronic acid (HA) in relieving lower urinary tract irritation symptoms in patients with urinary tract infections (UTIs) and bladder pain syndrome/interstitial cystitis (BPS/IC). This research, conducted in Romania, includes 30 patients with UTIs (Group I) and 24 with BPS/IC (Group II) as defined by European Association of Urology (EAU) Diagnostic Criteria. Data were collected prospectively, using pre- and post-treatment questionnaires for pelvic pain with a symptom scale for urination and frequency as well as visual analog scale (VAS) pain quizzes. At follow-up visits, at an average of 20 months, a significant improvement in urinary bladder pain, day-time urinary frequency and quality of life was observed in Group I patients. Group II patients experienced significant improvement in urinary bladder pain, urgency, nocturia and quality of life at the 15-month follow-up visit. Eighteen patients (75%) showed a complete response to intravesical HA instillations and required no further treatment. Our study demonstrates that intravesical HA instillations may be considered as an important treatment component, with long term positive effects in therapeutic strategy for optimal results in uncomplicated recurrent UTIs and BPS/IC, with good compliance and minimal side effects.

The Relation of Dependency and the Predictive Potential of Several Factors Possibly Involved in Determining Pulmonary Hypertension in Graves' Disease.

OBJECTIVES: To establish a possible relation of dependency between pulmonary hypertension (PHT) and several factors, with the evaluation of their predictive potential, in Graves' disease. METHODS: For identifying the factors implied in producing PHT and for evaluating its reversibility, we made echocardiography exams, sessions of monitoring the blood pressure during 24 hours and biological test in a group of 42 patients with Graves' disease (group H), comparing them with themselves in a euthyroid status (group E, n=25) and with a control group (group C, n=25). In order to analyse the relation of dependency between pulmonary hypertension (PHT) and the factors identified in the H group, we used both the simple linear regression method (polynomial of degree 1) and the non-linear regression method (polynomial of degree 2, 3) for establishing one model of functional dependency. We used the values of the coefficients of correlation r (degree of dependency) and of determination R2 (the type of dependency). The statistical test (F-test, AIC criterion, test t) was applied by choosing the most appropriate model of determination, with a higher predictive potential. RESULTS: We identified PHT at 47.6% of the patients with Graves' disease. Once the euthyroidism status is obtained, PHT is normalized. While inducing PHT, we identified a strong relationship of dependency on several possible new factors such as: pre-treatment period, age, level of the thyroid stimulating hormone receptor antibody and values of systolic blood pressure, besides the already known ones (high level of thyroids hormones, cardiac output, pulmonary vascular resistance). CONCLUSIONS: The non-linear model best explains the relation of determination between pulmonary pressure and those factors having a better predictive potential (from 51% to 90%), compared with the linear model, the only exception being the age factor and the systolic blood pressure, where both models seems to be appropriate.

Comparison of Linear and Non-linear Regression Analysis to Determine Pulmonary Pressure in Hyperthyroidism.

OBJECTIVES: This study aimed at assessing the incidence of pulmonary hypertension (PH) at newly diagnosed hyperthyroid patients and at finding a simple model showing the complex functional relation between pulmonary hypertension in hyperthyroidism and the factors causing it. METHODS: The 53 hyperthyroid patients (H-group) were evaluated mainly by using an echocardiographical method and compared with 35 euthyroid (E-group) and 25 healthy people (C-group). In order to identify the factors causing pulmonary hypertension the statistical method of comparing the values of arithmetical means is used. The functional relation between the two random variables (PAPs and each of the factors determining it within our research study) can be expressed by linear or non-linear function. By applying the linear regression method described by a first-degree equation the line of regression (linear model) has been determined; by applying the non-linear regression method described by a second degree equation, a parabola-type curve of regression (non-linear or polynomial model) has been determined. We made the comparison and the validation of these two models by calculating the determination coefficient (criterion 1), the comparison of residuals (criterion 2), application of AIC criterion (criterion 3) and use of F-test (criterion 4). RESULTS: From the H-group, 47% have pulmonary hypertension completely reversible when obtaining euthyroidism. The factors causing pulmonary hypertension were identified: previously known- level of free thyroxin, pulmonary vascular resistance, cardiac output; new factors identified in this study- pretreatment period, age, systolic blood pressure. According to the four criteria and to the clinical judgment, we consider that the polynomial model (graphically parabola- type) is better than the linear one. CONCLUSIONS: The better model showing the functional relation between the pulmonary hypertension in hyperthyroidism and the factors identified in this study is given by a polynomial equation of second degree where the parabola is its graphical representation.
