Cystic Dysplasia of the Testis: A Report of Three Cases and Review of the Literature

We describe the clinical and pathologic findings in three cases of cystic dysplasia of the testis and compare our findings to others in the English literature. The condition is characterized by dilatation of the rete testis with or without similarly affected adjacent structures. It is important to recognize this lesion for two reasons. First, it is associated with a high frequency of ipsilateral renal anomalies. Second, it is important to consider this condition in the differential diagnosis of cystic testicular mass in a neonate or a child. The management of this condition is quite different from the management of other testicular masses such as a hydrocele, testicular germ cell tumor, or infiltrative disorder (e.g., lymphoma, inflammation, torsion, or hematoma). Testicular cystic dysplasia is benign and the lesion can be removed surgically, leaving the rest of the testis intact. A discussion of the lesion's possible pathogenesis is also presented.     

Radiotherapy for melanotic freckles

Five patients who received radiotherapy (RT) for 7 melanotic freckles (MF, also known as Hutchinson's freckles, lentigo maligna) were reviewed 8 to 37 months after their treatment by RT. Local control and a favourable cosmetic result occurred in all patients. Treatment toxicity was minimal. Few reports about the use of RT for MF exist. Many other treatments including observation alone have been associated with high rates of recurrence, and in some cases conversion to invasive melanoma has occurred. RT appears to be a safe and effective treatment for this condition, providing that doses equivalent to 44 Gy in 11 fractions or more are given.     

Translation of the Leisure Satisfaction Scale into French: a validation study

Few standardized instruments are available for clients who speak languages other than English. The purpose of the study was to present and describe the process of translating an English standardized assessment into another language. Using the translation/validation methodologies described by Haccoun (1987) and Vallerand (1989), the Leisure Satisfaction Scale (LSS) was translated into French and then statistically validated. All correlations between both language versions of the LSS were found to be significant at the 0.01 level. Confirmatory factor analysis results were positive. Study findings indicate that the Haccoun (1987) and Vallerand (1989) methodologies provide clinicians with another option for ensuring culturally sensitive and relevant evaluations. Further research is needed to globally assess the measurement properties of the French version of this instrument.     

Fatigue as an important aspect of quality of life in patients with acute myeloid leukemia

Quality of life (QL) was evaluated in 101 patients with AML undergoing intensive and prolonged treatment at 12 sequential time points by using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C 30 questionnaire and the profile of mood states scale (POMS). For those patients having completed the course of inpatient treatment (n=37), QL improved from the beginning of chemotherapy to the end of inpatient treatment. Patients who subsequently went off protocol did not differ significantly in their self-assessed QL when compared with patients who completed therapy. Fatigue was more closely related to QL than nausea/emesis or appetite loss, but did not correlate with hemoglobin levels.     

Correlation between clinical syndromes and neuropsychological tasks in unmedicated patients with recent onset schizophrenia

The aim of this study is to circumscribe the cognitive deficits according to schizophrenic syndromes in a population of sub-acute untreated patients. We have studied the cross-sectional correlation between cognitive deficits and schizophrenic symptoms, in a group of 24 untreated patients (including 17 neuroleptic-naive patients) with recent onset of the disease. A task of alertness, a working memory (WM) test (including two levels of difficulty) and an abbreviated version of the Wisconsin Card Sorting Test (WCST) were selected. WM deficits and poor performance on the WCST were highly correlated with disorganized symptoms, modestly with the positive syndrome and not with the negative syndrome. Thus, disorganized symptoms, more than any other, appear to be related to the impairment of executive function and WM in recent onset unmedicated patients with schizophrenia.     

Depression and panic disorder after heart transplantation--treatment with sertraline

This report focuses on a case of major depression and panic disorder after heart transplantation. Due to these disorders, the male patient's compliance with cardiological treatment became increasingly insufficient. There are no controlled studies on psychopharmacological opportunities in cases such as this one. The patient was treated with sertraline and the outcome was healthy, without cardiovascular adverse effects or drug-drug interactions.     

An incidental finding of thymic carcinoid during urgent CABG operation

We present a case report of a 60-year-old Malay man who was undergoing an urgent coronary artery bypass graft (CABG) operation when a well encapsulated thymoma-like tumor was found incidentally. Total thymectomy was performed together with the CABG. Histopathological report of the tumor, however, confirmed a rare thymic carcinoid. The clinical features, management, and outcome of surgery are discussed.     

The haematopoietic effect of recombinant human erythropoietin in haemodialysis is independent of the mode of administration (i.v. or s.c.)

Background: Previous studies comparing intravenous (i.v.) and subcutaneous (s.c.) administration of recombinant human erythropoietin (rHuEpo) often did not achieve optimal iron reserve, were restricted to a limited follow-up period (not allowing equilibration) and/or did not exclude the role of other confounding factors. In addition all papers focused on the conversion from i.v. to s.c. Methods: In this study, 30 equilibrated patients on s.c. rHuEpo were randomized into two groups, one converting to i.v. after 6 months of follow-up and one remaining on s.c. rHuEpo. In both groups rHuEpo was administered three times weekly. Only patients completing a further 6 months follow-up were considered for statistical evaluation. Serum ferritin was targeted at 200 ng/ml and haematocrits between 28 and 35% were pursued. Results: The average haematocrit levels before conversion were 31.9±1.1% in the conversion group and 31.4±1.6% at the same time point in the non-conversion group (P-NS). After 6 months haematocrits were 31.5±0.5% in the conversion group and 31.1±0.9% in the non-conversion group (P=NS). Ferritin concentration in the conversion group was 219±49 ng/ml before and 230±83 mg/ml after the conversion. For the non-conversion group ferritin was 224±25 ng/ml and 236±52 ng/ml respectively (P=NS). The weight-standardized average rHuEpo dose per injection remained the same in the conversion group before and after conversion (44.0±1.8 U/kg/injection vs 45.4±4.7 U/kg/injection) P=NS). In the non-conversion group the corresponding rHuEpo doses were 32.9±4.2 U/kg/injection and 39.6±7.0 U/kg/injection respectively (P=NS). There were no differences in serum PTH, aluminium, vitamin B12, folic-acid levels, and intake of co-trimoxazole, ACE inhibitors or theophylline. Conclusion: No changes in rHuEpo dose wee observed after conversion from s.c. to i.v. There were no significant differences between the conversion and non-conversion group. These results are in contrast to some earlier studies suggesting lower rHuEpo requirements in case of s.c. administration.
