Background: Benign prostate hyperplasia (BPH) is a common age-dependent urological condition that can disrupt quality of life if the patient's treatment choice is inappropriate. 

Objectives: To examine whether patients’ demography and personality affect their decision regarding the type of treatment: namely, conservative or surgical. 

Methods: A total of 105 BPH patients treated during the period 2005–2008 were retrospectively categorized into three groups according to treatment received: (i) medication only (n=056), (ii) combined treatment (the initial medication treatment was switched to surgical treatment) (n=32), and (iii) surgery only (n=17). A prerequisite for inclusion in the study was use of BPH medication for at least half a year before the study (groups 1 and 2). These groups completed the International Prostate Symptom Score (IPSS) questionnaire at the start of BPH medical treatment (IPSS 1) and at the start of the trial (IPSS 2), and the staff calculated the difference (IPSS 1-IPSS 2 = Delta IPSS = DIPSS).  All three groups provided demographic data (age, country of origin, education) and completed tri-dimensional personality questionnaires (TPQ) to measure three independent "temperament" personality dimensions to evaluate how different individuals feel or behave: novel seeking (NS), harm avoidance (HA), and reward dependence (RD). Data were analyzed using chi-square, t-test, one-way ANOVA and logistic regression.

Results: Demographic variables and the RD dimension differed according to choice of BPH treatment. 

Conclusions: Our study suggests that symptomatic BPH treatment is influenced less by the patient's personality and more by his life circumstances. Israeli-born patients were more conservative, Russian-born patients were ambivalent, and other foreign-born patients predominantly preferred surgical treatment. We assume that personality has a more decisive effect on patients with malignant disease and they accept the medical advice more easily. 

 

Background: Numerous studies have shown an association between asthma and mental disorders. While elevated rates of asthma have been noted among psychiatric patients with anxiety disorders and post-traumatic stress disorder, several studies have found elevated rates of mental disorders among asthma patients. Such studies, however, have generally relied upon questionnaires and assessment by non-specialist physicians to diagnose mental disorders and asthma.

Objectives: To examine a possible association between asthma and psychiatric diagnoses in Israeli military recruits and soldiers.

Methods: In this cross-sectional study we compared the prevalence of mental diagnoses in asthmatic recruits and soldiers to that in non-asthmatic recruits and soldiers. A total of 195,903 recruits and soldiers were examined by Israel Defense Forces recruiting offices and fitness boards. Diagnoses of asthma were based on a pulmonologist's diagnosis, including spirometry at rest and exercise testing as indicated; diagnoses of mental disorders were based on examination by a psychiatrist.

Results: The prevalence of asthma was found to be 7.8% (current) and 9.8% (lifetime). The prevalence of mental disorders was 13.4%. Current asthma was associated with an increased likelihood of any mental disorder (OR = 1.20, 95% CI = 1.15–1.26), and specifically with mood and anxiety disorders (1.31, 1.19–1.46), introvert personality disorders (1.20, 95% 1.12–1.28) and adjustment disorder (1.43, 1.26–1.62). Lifetime asthma was associated with an increased likelihood of the same disorders, but the association was not as powerful.

Conclusions: The results validate the previously documented association between asthma and mental disorders, using a sample of unprecedented size and improved methodology. A multidisciplinary approach to asthma that incorporates mental health professionals in the treatment of poorly controlled asthma and perhaps of asthma in general is recommended.
 

Background: Transcobalamin II is a serum transport protein for vitamin B₁₂. Small variations in TC-II[1] affinity were recently linked to a high homocysteine level and increased frequency of neural tube defects. Complete absence of TC-II or total functional abnormality causes tissue vitamin B₁₂ deficiency resulting in a severe disease with megaloblastic anemia and immunologic and intestinal abnormalities in the first months of life. This condition was described in hereditary autosomal-recessive form. Low serum TC-II without any symptoms or clinical significance was noted in relatives of affected homozygotes.

Objectives: To study 23 members of a four-generation family with hereditary vitamin B₁₂ deficiency and neurologic disorders.

Methods: Thorough neurologic, hematologic and family studies were supplemented by transcobalamin studies in 20 family members.

Results: Partial TC-II deficiency was found in 19 subjects. Apo TC- II (free TC-II unbound to vitamin B₁₂) and total unsaturated B₁₂ binding capacity were low in all tested individuals but one, and holo TC-II (TC-II bound by vitamin B₁₂) was low in all family members. The presentation of the disease was chronic rather than acute. Early signs in children and young adults were dyslexia, decreased IQ, vertigo, plantar clonus and personality disorders. Interestingly, affected children and young adults had normal or slightly decreased serum vitamin B₁₂ levels but were not anemic. Low serum B₁₂ levels were measured in early adulthood. In mid-late adulthood megaloblastic anemia and subacute combined degeneration of the spinal cord were diagnosed. Treatment with B₁₂ injections resulted in a significant improvement. The pedigree is compatible with an autosomal-dominant transmission. This family study suggests a genetic heterogeneity of TC-II deficiency.

Conclusions: We report the first family with a hereditary transmitted condition of low serum TC-II (partial TC-II deficiency) associated with neurologic and mental manifestations in childhood. Partial TC-II deficiency may decrease the amount of stored cobalamin, resulting in increased susceptibility to impaired intestinal delivery of cobalamin and predisposing to clinically expressed megaloblastic anemia at a later age. Partial TC-II deficiency should be suspected in families with megaloblastic anemia and in individuals with neurologic and mental disturbances – despite normal serum vitamin B₁₂ levels. Low serum UBBC[2] and apo TC-II should confirm the diagnosis. Early vitamin B₁₂ therapy may prevent irreversible neurologic damage.
