Specific nonsurgical therapy in male infertility

Although the objective of this article was to discuss the specific medically treatable causes of male infertility, the reader will be impressed by the fact that many of the treatments seem less than "specific." The need to treat infections to improve fertility is ill defined. The utilization of a scrotal cooling device as "specific" nonsurgical treatment for varicocele is yet to be defined. Immunologic suppression is indeed a specific form of therapy for a measurable phenomenon; unfortunately, the significance of that phenomenon as well as the best means and location of its assessment are undergoing significant reevaluation. An exciting frontier is the prospect of preventing infertility in the patient undergoing therapy for cancer, thus obviating the need for treatment of the ensuing infertility. Before specific therapies can be anticipated to have a predictable beneficial effect, these areas require active investigation to define the problem more clearly.     

Forfeiture of the proceeds of drug trafficking

The Hodgson Committee in its report on "The Profits of Crime and Their Recovery", which is being examined by the Government of the United Kingdom of Great Britain and Northern Ireland, made a number of recommendations relating to forfeiture and confiscation of the proceeds of crimes. The Committee, inter alia, recommended that the criminal courts should have the power to order the confiscation of the proceeds of crimes but that there should be a prescribed minimum amount below which no confiscation order could be made. This article comments on those recommendations relating to the proceeds of drug crimes, and suggests three possible ways of developing international cooperation to secure the tracing or confiscation of illegally acquired assets held abroad. The alternatives suggest either extending national laws to deal with these problems, in accordance with the provisions of the Single Convention on Narcotic Drugs; or following the example of Canada, where it is understood to be an offence to receive or possess the proceeds of crime irrespective of whether or not that crime took place in Canada; or developing a more extensive extra-territorial jurisdiction, for which there are precedents in the field of terrorism. One of the two annexes to this article describes recent initiatives within the Council of Europe to promote co-operation in tracing, freezing and confiscation of assets arising from drug trafficking, and the other provides an example of bilateral agreement (Cayman Islands) on disclosure of banking arrangements.     

Comparison of renal function after open radical cystectomy,extracorporeal robot assisted radical cystectomy,and intracorporeal robot assisted radical cystectomy

PurposeRenal function outcomes following robot-assisted radical cystectomy (RARC) have not been well established. We sought to compare long-term renal function outcomes between open radical cystectomy, RARC with extracorporeal urinary diversion and intracorporeal urinary diversion at a high volume institution.Materials and MethodsWe retrospectively reviewed our institutional bladder cancer database for patients who underwent RC from 2010 to 2019 with pre-operative estimated glomerular filtration rate (eGFR) > 45 ml/min/1.73m². Changes in renal function were assessed through locally weighted scatter plot smoothing and comparison of median eGFR between surgical groups. Chronic Kidney Disease Stage 3B was defined as eGFR < 45 ml/min/1.73m². Renal function decline was defined as a ≥10 ml/min/1.73m² drop in eGFR. Kaplan Meier method with log-rank was used to compare CKD 3B-free survival and renal function decline. Cox Proportional Hazards model was used to identify predictors of CKD 3B.ResultsSix hundred and forty four patients were included with median follow-up of 32 months (IQR 12–56). Preoperative characteristics were similar among the groups with no differences in median pre-operative eGFR (ORC: 74.6, extracorporeal urinary diversion: 74.3, intracorporeal urinary diversion: 71.6 ml/min/1.73m², P = 0.15). Median postoperative eGFR on follow up was not different between groups (P = 0.56). 33% of patients developed CKD 3B. There were no differences in CKD 3B-free survival by surgical approach (P = 0.23) or urinary diversion (P = 0.09). 64% of patients experienced renal function decline with a median time of 2.4 years (P 0.23). Predictors of CKD were pathologic T3 disease or greater (HR: 1.77, P = 0.01), ureteroenteric anastomotic stricture (HR: 2.80, P < 0.001), preoperative CKD Stage 2 (HR: 1.81, P =0.02), and preoperative CKD Stage 3A (HR: 5.56, P < 0.001).ConclusionRenal function decline is common after RC. Tumor stage, pre-operative eGFR, and ureteral stricture development, not surgical approach, influence renal function decline.

Osteoid osteoma: a diagnostic problem

A 32-year-old patient is presented to draw the attention of physical therapists to the diagnosis of osteoid osteorna, particularly in patients after an athletic injury. Osteoid osteorna is a benign neoplasm, but it can cause substantial pain and disability. This paper is not intended to add another case to the 400 already published, but rather to point out the difficulty in diagnosing osteoid osteorna despite modern laboratory findings and a classical history of pain responsive to salicylates only. Surgical excision of an osteoid osteorna, if diagnosed and present, is always indicated. It brings complete relief and eliminates any further need for physical therapy. In order to be certain that the nidus is excised, an x-ray of the specimen should be taken. J Orthop Sports Phys Ther 1983;5(1):33-35.     

Thyroid function in a population of children with attention deficit hyperactivity disorder

To determine the prevalence of thyroid hormone abnormalities and generalized resistance to thyroid hormone in a population of children with attention deficit hyperactivity disorder (ADHD) as compared to reference ranges determined from a control population and hence to determine if routine thyroid hormone screening in children with non-familial ADHD is indicated.

Method:

Children attending the State Child Development Centre in Perth, Western Australia with ADHD, as defined by the Diagnostic and Statistical Manual of Mental Disorders (fourth edition) provided the study population. The control population consisted of 353 normal children with a history of allergy in whom radioallergosorbent (RAST) testing was being performed.

Results:

The prevalence of thyroid hormone abnormalities in the study population was 2.3% (95% CI 0.6%, 5.7%). There were no cases of generalized resistance to thyroid hormone. The prevalence of thyroid hormone abnormalities in the general population of children and adolescents has been reported to vary between 1 and 3.7%.

Conclusion:

Routine thyroid hormone screening is not indicated in children with non-familial ADHD.     

Rising incidence of type 1 diabetes in Scottish children, 1984-93. The Scottish Study Group for the Care of Young Diabetics

OBJECTIVES: To calculate the incidence of type 1 diabetes in Scottish children aged less than 15 years between 1984 and 1993; to examine changes in incidence; and to calculate the prevalence of diabetes at the end of this period. DESIGN: Three data sources were used to construct the Scottish Study Group for the Care of Young Diabetics register: active reporting of all new cases; reports from the Scottish Morbidity Register 1; and local registers. SUBJECTS: All children resident in Scotland diagnosed with primary insulin dependent diabetes mellitus when less than 15 years of age between 1984 and 1993. MAIN OUTCOME MEASURES: Annual incidence and prevalence rate for Scotland; time trend in incidence over the 10 years; differences in incidence between the three different age groups; and completeness of the register. RESULTS: The average annual incidence for Scotland was 23.9/100,000 children. The prevalence rate was 1.5/1000 in 1993. A total of 2326 cases was identified from the three sources. Capture-recapture analysis suggests a case ascertainment of 98.6%. The annual incidence rates increased at a rate of 2% each year (rate ratio = 1.02, 95% confidence interval (CI) 1.01 to 1.03). The incidence was higher in boys than girls (rate ratio = 1.08, 95% CI 1.00 to 1.18), and the incidence rates increased with age: 15.3/100,000/year for age 0-4 years, 24.4/ 100,000/year for age 5-9 years, and 31.9/ 100,000/year for age 10-14 years. CONCLUSIONS: The incidence of type 1 diabetes in Scotland is increasing and the prevalence is relatively high. These findings have important implications for health service resource allocation. The Scottish Study Group for the Care of Young Diabetics' register provides a base for monitoring and research.     

High-density lipoprotein subclasses and esterification rate of cholesterol in children: effect of gender and age

Since the development of coronary heart disease (CAD) is affected by a specific pattern of plasma high density lipoprotein (HDL) effects it may be useful to know whether this occurs already in childhood. In this study we evaluated particle size distribution of HDL by gradient gel electrophoresis and the determination of cholesterol esterification rate (FER_HDL) in plasma depleted of apo B lipoproteins in 221 children (108 boys and 113 girls) aged 4 months to 20 years. Total plasma- (TC), low-density lipoprotein- (LDL-C) and HDL- (HDL-C) cholesterol, HDL unesterified cholesterol (HDL-UC) and plasma triglycerides (TG) were also measured. There were no significant gender and age differences with respect to the plasma TC, LDL-TC and TG but concentration of HDL-TC increased with age. Post-pubertal girls had significantly higher relative concentrations of HDL_2b compared to boys (30.4% vs 17.2%), while HDL_3b,c was lower in post-pubertal girls (8.7% vs. 16.5 %). FER_HDL correlated inversely with HDL_2b and positively with HDL_3b,c particles and was significantly higher in boys of the post-pubertal group compared to girls (16.9%/h vs 12.5%/h). While in girls there was a positive correlation between age and HDL-C, HDL-UC and the relative concentration of HDL_2b no significant correlation were observed in boys. In girls the increase in TC showed a significant correlation with a simultaneous increase in HDL-C, HDL-UC and HDL_2b. In boys TC correlated significantly with changes in TG only. When HDL_2b and HDL_3b,c cholesterol levels are calculated from HDL-C concentration and per cent distribution the differences between males and females are further emphasized. These data indicate that HDL particle size distribution is age- and gender-dependent.
