Do transsexuals have micturition disorders?

OBJECTIVE: Transsexualism occurs with an estimated prevalence of 2.4:100,000 male-to-female (MTF) and 1:100,000 female-to-male (FTM) transsexuals. As sex reassignment surgery involves surgery of the urethra and transsexuals are substituted life-long with the cross gender hormones there could possibly arise micturition disorders. Aim of the study was to determine if transsexuals have an increased risk of micturition disorders and if so which. STUDY DESIGN: Between January and July 2003 we examined 25 transsexuals whereof 18 were MTF and 7 were FTM transsexuals using King's Health Questionnaire, visual analogue scale for patient's well being, perineal and transabdominal ultrasound, urine dipstick and uroflow measurement. RESULTS: 17 out of 25 patients considered themselves very happy. In MTF transsexuals, a diverted stream, overactive bladder and stress urinary incontinence was a common problem. Prostate volume was small with 20 g and palpation did not confirm and solid or suspicious lesions. None of the patients had significant residual urine but MTF transsexuals had a reduced urinary flow. We could not detect a current urinary tract infections in any of the patients. CONCLUSION: Transsexuals have an increased risk for the development of micturition disorders including stress urinary incontinence and overactive bladder compared to age-matched control groups and should be counselled preoperatively. Reasons for the development of incontinence might be surgery including pudendal nerve damage, hormonal reasons and ageing.

Prescription procedures in medication for relapse prevention after inpatient treatment for alcohol use disorders in Switzerland

In randomized controlled trials with high internal validity, pharmacotherapy using acamprosate, naltrexone, and, to a somewhat lesser extent, disulfiram has proved effective in preventing relapse in patients with alcohol use disorders (AUD). There remains, however, a paucity of studies with sufficient external validity in which the effectiveness of pharmacotherapy in clinical practice is investigated. This study aimed to make a contribution to close this gap in research.

Eosinophilic disorders

Eosinophilic inflammatory responses occur in association with multiple disorders. Although the initial cause and the affected organs vary among the different eosinophilic disorders, there are only 2 major pathways that mediate eosinophilia: (1) cytokine-mediated increased differentiation and survival of eosinophils (extrinsic eosinophilic disorders), and (2) mutation-mediated clonal expansion of eosinophils (intrinsic eosinophilic disorders). Independent from the original trigger, the most common cause of eosinophilia is the increased generation of IL-5-producing T cells. In some cases, tumor cells are the source of eosinophil hematopoietins. The intrinsic eosinophilic disorders are characterized by mutations in pluripotent or multipotent hematopoietic stem cells leading to chronic myeloid leukemias with eosinophils as part of the clone. Here, we propose a new classification of eosinophilic disorders on the basis of these obvious pathogenic differences between the 2 groups of patients. We then discuss many known eosinophilic disorders, which can be further subdivided by differences in T-cell activation mechanisms, origin of the cytokine-producing tumor cell, or potency of the mutated stem cell. Interestingly, many subgroups of patients originally thought to have the idiopathic hypereosinophilic syndrome can be integrated in this classification.

[Emotion activation in personality disorders]

There are at least six psychotherapeutic treatments of personality disorders having received empirical and clinical validation in terms of their efficacy. These treatments are based on different theoretical models, namely the cognitive-behavioural, psychodynamic and interpersonal models. This article briefly presents these treatments, focusing on the process of therapeutic change. It is assumed that the process of emotional activation is one of the most interesting theoretical psychotherapy ingredient in treatments of these patients. The treatments are discussed regarding this hypothesis and its clinical implications.

[Evaluation of the "Schema-focused Emotive Behavioural Therapy" (SET) for Patients with Personality Disorders: Results of a Randomised Controlled Trial.]

The "Schema-focussed Emotive Behavioral Therapy" (SET) was developed by our research group as a new group therapy approach for patients with personality disorders from all clusters (A to C; DSM-IV). It was evaluated in a randomised controlled study (n = 93). Data were collected before and after treatment as well as one year after study entry. A completer analysis was conducted with matched subgroups (n = 60). After therapy, SET patients improved in the outcome domains interactional behavior, strain, and symptomatic complaints (IIP-D, GAF, VEV-VW, BSI-P). Furthermore, they showed a significant lower dropout rate. At the follow-up assessment, Cluster C patients of the experimental group deteriorated with regard to symptomatic complaints (BSI-P). In contrast, cluster B patients improved more over time compared to control subjects. SET seems to be an adequate and effective group therapy with effects that seem to be stable over time, especially for patients with Cluster B diagnosis.

A thiazide test for the diagnosis of renal tubular hypokalemic disorders

Although the diagnosis of Gitelman syndrome (GS) and Bartter syndrome (BS) is now feasible by genetic analysis, implementation of genetic testing for these disorders is still hampered by several difficulties, including large gene dimensions, lack of hot-spot mutations, heavy workup time, and costs. This study evaluated in a cohort of patients with genetically proven GS or BS diagnostic sensibility and specificity of a diuretic test with oral hydrochlorothiazide (HCT test). Forty-one patients with GS (22 adults, aged 25 to 57; 19 children-adolescents, aged 7 to 17) and seven patients with BS (five type I, two type III) were studied; three patients with "pseudo-BS" from surreptitious diuretic intake (two patients) or vomiting (one patient) were also included. HCT test consisted of the administration of 50 mg of HCT orally (1 mg/kg in children-adolescents) and measurement of the maximal diuretic-induced increase over basal in the subsequent 3 h of chloride fractional clearance. All but three patients with GS but no patients with BS and pseudo-BS showed blunted (<2.3%) response to HCT; patients with BS and the two patients with pseudo-BS from diuretic intake had increased response to HCT. No overlap existed between patients with GS and both patients with BS and pseudo-BS. The response to HCT test is blunted in patients with GS but not in patients with BS or nongenetic hypokalemia. In patients with the highly selected phenotype of normotensive hypokalemic alkalosis, abnormal HCT test allows prediction with a very high sensitivity and specificity of the Gitelman genotype and may avoid genotyping.

Expression of TCL1 in hematologic disorders

OBJECTIVE: TCL1, MTCP1 and TCL1b are three members of a new family of oncogenes that are expressed in T cell leukemias of ataxia telangiectasia patients (T-PLL, T-CLL). TCL1 is located at 14q32.1 and activated by juxtaposition to the alpha/delta-locus at 14q11 or beta-locus at 7q35 of the T cell receptor during the reciprocal translocations t(14;14)(q11;q32), t(7;14)(q35;q32), or inversion inv(14)(q11;q32). TCL1 encodes a predominantly cytoplasmic protein of 114 aa (14 kD) of unknown function. Recent studies suggest that TCL1 promotes cell survival rather than stimulating cell proliferation, as previously proposed. METHODS: In an attempt to clarify the contexts in which TCL1 is expressed, we investigated TCL1 expression in 114 lymphoma and leukemia patients by Northern blot, RT-PCR and immunohistochemistry. RESULTS: TCL1 expression is restricted to lymphoid cells, and is found in neoplastic (T and B cell neoplasms, and Hodgkin's disease) and nonneoplastic proliferations (reactive lesions). Out of 114 cases, 18 neoplasms of myeloid and 4 cases of epithelial origin were TCL1-negative. In lesions of the lymphoid system, both low- and high-grade lymphomas were found to express TCL1. CONCLUSIONS: We propose that TCL1 expression especially in high-grade B cell non-Hodgkin's lymphomas might interfere with B cell differentiation and promote the transition from low- to high-grade lymphoma.

Modeling the influence of APOC3, APOE, and TNF polymorphisms on the risk of antiretroviral therapy-associated lipid disorders

BACKGROUND: Single-nucleotide polymorphisms in genes involved in lipoprotein and adipocyte metabolism may explain why dyslipidemia and lipoatrophy occur in some but not all antiretroviral therapy (ART)-treated individuals. METHODS: We evaluated the contribution of APOC3 -482C-->T, -455T-->C, and 3238C-->G; epsilon 2 and epsilon 4 alleles of APOE; and TNF -238G-->A to dyslipidemia and lipoatrophy by longitudinally modeling >2600 lipid determinations and 2328 lipoatrophy assessments in 329 ART-treated patients during a median follow-up period of 3.4 years. RESULTS: In human immunodeficiency virus (HIV)-infected individuals, the effects of variant alleles of APOE on plasma cholesterol and triglyceride levels and of APOC3 on plasma triglyceride levels were comparable to those reported in the general population. However, when treated with ritonavir, individuals with unfavorable genotypes of APOC3 and [corrected] APOE were at risk of extreme hypertriglyceridemia. They had median plasma triglyceride levels of 7.33 mmol/L, compared with 3.08 mmol/L in the absence of ART. The net effect of the APOE*APOC3*ritonavir interaction was an increase in plasma triglyceride levels of 2.23 mmol/L. No association between TNF -238G-->A and lipoatrophy was observed. CONCLUSIONS: Variant alleles of APOE and APOC3 contribute to an unfavorable lipid profile in patients with HIV. Interactions between genotypes and ART can lead to severe hyperlipidemia. Genetic analysis may identify patients at high risk for severe ritonavir-associated hypertriglyceridemia.

Pathological baroreceptor sensitivity in patients suffering from somatization disorders: do they correlate with symptoms?

We conducted a study to investigate whether patients with somatization disorders (ICD-10, F45.0) show abnormal values in autonomic testing.

[Autonomic neuropathy in somatization disorders]

AIM: We conducted a study to investigate whether patients with somatization disorder show abnormal values in autonomic testing, especially in the central baroreceptor sensitivity. PATIENTS AND METHODS: Seventy-one patients were included. All had a diagnosis of somatization disorder (ICD-10, F45.0). Psychometric testing was performed by means of validated questionnaires (STAI, STAXI, FPI, GBB, ADS, SOMS, SCL-90-R). Autonomic regulation was analyzed by international standards using frequency spectral calculation by fast Fourier transformation. Thereby 3 different groups were detected: 12 patients with a baroreceptor sensitivity (BRS) of less than 3.0 ms/mm Hg, 20 patients with normal BRS (> 9.0 ms/mm Hg), and an in-between group (n = 39) with intermediate BRS. Controlling for age, a covariance analysis was calculated. RESULTS: The two extreme groups showed no difference in psychometric testing. However, significant differences were discernible in spectral values of mid-frequency-band (p < 0.05) in a covariance analysis with age as covariate. Equally the 24 h blood pressure determination showed significantly higher values for the group with BRS < 3.0 ms/mm Hg (p < 0.05 to 0.001). CONCLUSIONS: In a high percentage (17 %) of patients diagnosed to have somatization disorder autonomic dysregulation becomes apparent and is accompanied by increased blood pressure. Therefore it doesn't seem accurate to overlook concomitant organic lesions in somatization disorders despite patients lacking overtly clinical signs but suffering from various unspecific symptoms.

Disorders of paravertebral lumbar muscles: from pathology to cross-sectional imaging

Paravertebral lumbar muscles are important for spine stabilization and mobility. They may be abnormal in several disorders that may be associated with pain or functional impairment. Special attention should be paid to the paravertebral muscles during imaging, so that a possible muscular disease is not overlooked, especially in patients with low back pain. This article reviews such imaging abnormalities.
