Diagnosis and imaging in urinary tract infections.

The aim of imaging in urinary tract infection is to detect conditions that must be treated in order to avoid immediate deterioration or recurrences, and probable long-term kidney damage. In newborns identified with hydronephrosis during pregnancy or by neonatal screening, vesicoureteral reflux and renal scarring are congenital and not caused by infection. Most of these patients are male and the vesicoureteral reflux is of a higher grade than that detected in girls having had urinary tract infection. In children with urinary tract infection, several authors advocate a more selective policy and recommend imaging only in those children who are at risk for developing renal damage. In adult females no imaging is necessary in cystitis, whereas ultrasonography and plain films are recommended in acute pyelonephritis. Because uncomplicated urinary tract infection in men is rare, diagnostic evaluation including imaging should be started early in order to rule out complicating factors within the urinary tract. The role of imaging in prostatitis, vesiculitis, epididymitis and orchitis is primarily to rule out abscess formation, but also to exclude testicular malignancies.

Seminomas with exclusive intertubular growth: a report of 12 clinically and grossly inconspicuous tumors.

Intertubular growth in seminoma is characterized by seminoma cells, either singly or in small clusters, between preserved seminiferous tubules. It is a common, although focal, pattern in many seminomas where it is admixed with the usual sheet-like and nested arrangements and does not pose any diagnostic problems in such cases. We describe, in contrast, the clinicopathologic features of 12 cases with exclusively intertubular growth and which were typically diagnostically problematic. The 12 patients lacked overt clinical signs of a primary testicular mass. Three presented with infertility, 2 with cryptorchidism, 2 with metastases, 1 with pain and testicular atrophy, and the presentation was unknown in 4. On gross examination, no mass was apparent in 9 cases with available data, but ill-defined firm areas or foci of whitish-brown discoloration were occasionally noted. Microscopically, the process was characterized by individual, dispersed tumor cells or small clusters of cells growing between the seminiferous tubules. The tumor cells were often obscured by a lymphocytic infiltrate or, less commonly, nodules of hyperplastic Leydig cells. Common associated findings were tubular atrophy with sclerosis and thickening of tubular basement membranes and intratubular germ cell neoplasia, unclassified type. Immunostains against placental-like alkaline phosphatase and c-KIT (CD117) highlighted the seminoma cells in all cases examined. In pure form, intertubular seminoma is both clinically and pathologically inconspicuous and may be misdiagnosed as atrophy, scar, or orchitis.

Causes and mechanism of autoimmune disease: cyclosporin A as a probe for the investigation.

Organ-specific autoimmune disease can be elicited in rodents by manipulating the thymus/T cells. For example, elimination of a particular T-cell subset causes organ-specific autoimmune diseases, such as thyroiditis and gastritis, in otherwise normal mice. Environmental agents can cause similar autoimmune diseases by affecting the thymus/T cells. Cyclosporin A (CsA), a potent immunosuppressive drug, is an example. When a particular strain of newborn mice are daily administered with CsA for a limited period, they spontaneously develop organ-specific autoimmune disease, such as gastritis with anti-parietal cell autoantibodies, later in life. CsA abrogates the production of CD4+T cells and CD8+T cells in the thymus. Consequently, these T cells are substantially depleted from the peripheral lymphoid organs, especially when the drug is administered from the day of birth. The autoimmune disease is prevented when CsA-treated newborn mice are inoculated with splenic T cells from normal syngeneic adult mice. On the other hand, removal of the thymus immediately after neonatal CsA treatment produces autoimmune disease with a higher incidence and in a wider spectrum of organs, i.e., thyroiditis, sialoadenitis of the salivary gland, gastritis, insulitis of the endocrine pancreas, adrenalitis, oophoritis, or orchitis. Each autoimmune disease is accompanied by the development of circulating autoantibodies specific for the corresponding organ-specific antigens. These findings taken together indicate that CsA causes autoimmune disease not by affecting the target self-antigens, but by interfering with a thymus/T cell-dependent control mechanism on the production/expansion of pathogenic self-reactive T cells. Various other environmental insults (such as ionizing radiation or virus) can also cause similar autoimmune diseases, presumably by a similar mechanism.

Fatal mumps myocarditis.

A case of fatal mumps myocarditis in a 38-year-old male is reported. The disease started with orchitis, and severe cardiac symptoms developed within 1 1/2 month. The patient died 5 months later from congestive heart failure. The possible interrelation between late stages of viral myocarditis and dilated (congestive) cardiomyopathy is emphasized.

Congenital bilateral anorchia in childhood: a clinical, endocrine and therapeutic evaluation of twenty-one cases.

An evaluation of twenty-one boys, including a discordant pair of identical twins, is presented in whom bilateral anorchia was found with a negative family history and without history of breech presentation or of postnatal testicular trauma, torsion or orchitis. The most likely cause is prenatal testicular torsion. The incidence of the condition in our hospital is 1 in 177 cases of cryptorchidism. Prepubertal growth was normal before treatment, and testosterone replacement therapy allowed a normal pubertal growth spurt and skeletal maturation. Although demonstrable basal urinary testosterone was found in the subjects with a postpubertal bone age, most patients tested showed no increase after stimulation with human chorionic gonadotrophin. In the presence of a normal penis and scotum, such findings, together with a high basal FSH and an increased response of plasma LH to LHRH, make surgical exploration unnecessary. In the rare patient who shows a positive but subnormal response of testosterone to HCG, Leydig cells are presumed to be present either ectopically or in rudimentary testes, and further surgical exploration is indicated.

Fine needle aspiration of epididymal nodules in Chandigarh, north India: an audit of 228 cases.

BACKGROUND: Epididymal nodules are not infrequently encountered in surgical practice. These are generally small and slippery and fine needle aspiration cytology (FNAC) is not easy. But as it is rapid and less traumatic than a biopsy, this is a favoured technique in the assessment of epididymal nodules. PATIENTS AND METHODS: In the present study, all the cases of epididymal nodules aspirated from January 1998 to August 2004 were retrieved from the cytology files of the Department of Cytology, Post Graduate Institute of Medical Education and Research, Chandigarh, India. RESULTS: A total of 228 cases were retrieved and divided as follows: tuberculous epididymitis 70 (30.7%), non-specific inflammation 10 (4.4%), microfilaria 2 (0.9%), hydrocele 26 (11.4%), spermatocele 42 (18.4%), spermatic granulomas 12 (5.3%), adenomatoid tumour 3 (1.3%), leiomyosarcoma 1 (0.4%) and lipoma 1 (0.4%). Thirty-six (15.8%) cases were labelled as benign aspirate not otherwise specified. FNAC material was inadequate for opinion in 22 (9.65%) cases and three (1.3%) cases revealed evidence of a haematoma. CONCLUSIONS: FNAC was useful in the diagnosis of 90.3% of cases, thereby avoiding surgical biopsy and other investigations. Therefore, FNAC has an important role in the differential diagnosis of epididymal nodules as it can detect malignancy and benign conditions such as tuberculosis and acute and chronic epididymo-orchitis.

Sperm nuclear instability and staining with aniline blue: abnormal persistence of histones in spermatozoa in infertile men.

During mammalian spermiogenesis, replacement of the somatic histones by basic proteins, the protamines, allows normal sperm nuclear condensation. In this study we have evaluated the degree of chromatin compaction in spermatozoa from 191 infertile subjects, affected by different testicular disorders, compare with that in 50 fertile sperm donors (controls). In infertile men, there was a higher percentage of unstable spermatozoa after incubation with sodium dodecyl sulphate (SDS) and of stained spermatozoa after staining with aniline blue (P less than 0.001 vs. controls). Furthermore, a positive linear correlation was found between SDS-unstable spermatozoa and stained spermatozoa (P less than 0.001), suggesting that sperm instability was related to a defect in histone-replacement by sperm-specific nucleoproteins, protamines. When the patients were considered according to pathology, high sperm nuclear instability and a high percentage of stained spermatozoa were detected in groups affected by varicocele, idiopathic infertility and in patients with a history of unilateral cryptorchidism. In the latter group the same alterations were observed even when the cryptorchid testis had been removed during surgery. In the group with a past history of mumps orchitis these parameters did not show any difference when compared with controls.

Induction of spermatogenesis with gonadotrophins in Chinese men with hypogonadotrophic hypogonadism.

The effects of gonadotrophin administration to 17 Chinese patients with hypogonadotrophic hypogonadism (HH) on testicular volume and induction of spermatogenesis were studied. Ten subjects had isolated HH and seven had hypopituitarism. Twelve of the subjects had prepubertal onset of HH and five of them had been treated previously with hCG for induction of puberty. None had a history of cryptorchidism. During hCG treatment for induction of spermatogenesis, all subjects had an increase in serum levels of testosterone into the normal adult male range and their testes increased in size from 3 (1-20) ml to 11.6 (5-20) ml [median(range), p < 0.02]. Six subjects required treatment with hCG alone. However, the remaining 11 subjects, after at least 6 months treatment with hCG, required the addition of human menopausal gonadotrophin (hMG) to induce spermatogenesis. Two subjects remained azoospermic. One had a history of mumps orchitis and the other had isolated elevation of blood FSH levels, suggestive of primary testicular failure in addition to HH. Excluding one subject with fertile eunuch syndrome, the mean duration for first appearance of spermatozoa was 13 (4-52) months. Twelve subjects became fertile and pregnancy was achieved in their partners after 20 (4-78) months. The weekly doses for hCG and hMG were 4000 (3000-10,000) IU and 225 (225-450) IU, respectively. Patients who responded to hCG alone had a significantly larger pretreatment testicular volume, suggesting that they had only partial gonadotrophin deficiency. Prepubertal onset of hypogonadism was not a determining factor for requirement of hMG treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Fertility of men following inguinal hernia repair.

Among 8500 patients attending the fertility clinic due to infertility, 565 men (6.65%) reported an incidence of inguinal hernioplasty with or without subsequent atrophy of the testis. Semen quality (sperm concentrations, motility, and morphology) of these patients was markedly reduced in comparison to that of fertile men. In cases where hernioplasty was followed by atrophy of the testis, damage to sperm characteristics and Sertoli cell function was found to be far greater. This was also reflected in significant serum follicle stimulating hormone elevation (P less than 0.0025). No changes in luteinizing hormone and testosterone were found. No correlation was found between age of hernioplasty and semen quality following operation. The reasons for testicular damage may be due to ischaemic orchitis or immunological reactions.

Increased levels of interleukin-8 in human seminal plasma.

The role of cell-mediated immunity in the aetiopathogenesis of male infertility is far from being defined. The cytochemokine interleukin-8 (IL-8) has a key role in T-cell mediated immune responses. The aim of this study was to confirm the presence of IL-8 in human seminal plasma, to show differences between IL-8 concentrations in fertile and infertile subjects, and to show the potential relationship between IL-8 amounts in semen and spermiogram parameters. IL-8 levels were determined in the seminal plasma of 77 men divided as follows: (a) into seven groups according to the aetiological diagnosis of fertility and (b) into two groups on the basis of a normal or abnormal spermiogram. The mean value of IL-8 in the seminal plasma was 31.5 times higher than the upper limit in normal serum. There is a borderline statistical significant difference among the means of the various groups (P < 0.051). The Tukey's HSD test for multiple comparisons indicated no two groups as being significantly different, whereas the less conservative test LSD showed significant differences between the group with infection and groups with normal controls, Klinefelter's syndrome, mumps orchitis, cryptorchidism, or varicocele. There was no significant difference in IL-8 levels between men with normal and those with abnormal spermiograms. Furthermore, there was no correlation between IL-8 levels and the variables of the spermiogram. Even though the conclusions of this study have to be tempered by the sample size, IL-8 concentration in seminal plasma may be considered as a potential marker for the diagnosis of male accessory gland infection.

Relapse of brucellosis simulating testis tumor.

We report on a case of a 32-year-old man referred for evaluation of a painless left testicular mass suggesting a testicular tumor. Previous history was uneventful except for a 3-year history of systemic brucellosis without epididymo-orchitis. Radical inguinal orchidectomy was performed. Clinical and histopathological findings indicated a brucellar abscess of the left testis. Even in the absence of systemic symptoms, the possible relapse of brucellosis as an abscess formation in the testis should be considered as a rare cause of testicular mass in patients who live in endemic regions.

Color Doppler ultrasonography as a routine clinical examination in male infertility.

AIM: We assessed the value of scrotal color Doppler ultrasonography as a routine examination in infertile men. METHODS: Color Doppler ultrasonography was performed in 545 infertile men with a mean age of 35.8 years to detect intrascrotal abnormalities. Findings were compared with those of physical examination. RESULTS: Intrascrotal abnormalities were detected by ultrasonography in 65.3% of patients. Of 374 abnormalities, 58.3% were undetected by physical examination. Left varicocele was found in 313 patients (57.4%); testicular microlithiasis in 30 (5.5%); epididymal cyst in 21 (3.9%); right varicocele in 4 (0.8%); and testicular cysts in 3 (0.6%). One occurrence each (0.2%) was found for testicular tumor, intrascrotal hemangioma, and hydrocele of the spermatic cord. Compared to ultrasonography, sensitivity in detecting left varicocele by physical examination was 58.4%; specificity, 79.3%; accuracy, 67.3%; and positive predictive value, 79.3%. Venous diameters in the pampiniform plexus were 3 mm or more in 61.5% of 130 subclinical left varicoceles. Of 30 patients with testicular microlithiasis, 14 had varicocele, 2 had epididymal cyst,s 3 had a history of mumps orchitis, 1 had retractile testis, and 1 had a history of orchiectomy for contralateral testicular tumor. CONCLUSIONS: The routine Color Doppler ultrasonography is valuable for diagnosing scrotal abnormalities in infertile men, frequently detecting non-palpable lesions.

Bilateral testicular and adrenal malignant lymphoma of pre B-cell type.

A rare case of pre B-lymphoblastic lymphoma of the testes and adrenal glands is presented. No lymph node, central nervous system or bone marrow involvement was demonstrated at diagnosis. The primary presentation was of acute unilateral pain and swelling, mimicking simple orchitis. The diagnosis was made using aspiration cytology and the lymphoma characterized using immunohistochemical, electron microscopic and karyotype analysis techniques. Pre B-cell markers were clearly demonstrated by all criteria used. Monoclonal antibodies (FMC 29 and FMC 31) were used to define the early B-cell nature of the lymphoma. Confirmation using karyotype analysis in addition to immunoglobulin and T-cell beta-receptor gene rearrangement was obtained. Intrathecal chemotherapy was used prophylactically. Combination chemotherapy produced regression of the primary lymphomatous lesions, but subsequent bone marrow spread led to death.

Indications for ultrasound in the evaluation of the pathological scrotum.

Scrotal ultrasound scans carried out on 156 patients were reviewed in a retrospective study and the sonographic findings and indications evaluated. Ultrasound was able accurately to distinguish the normal from the pathological scrotum. Extratesticular lesions were readily differentiated from testicular lesions. Abnormal testicular echo patterns were usually associated with tumours, but orchitis, granulomas and haematomas were found to have a similar appearance. Occult testicular tumours could readily be identified. Ultrasound was also useful in excluding underlying pathology in hydroceles, in the diagnosis and follow-up of epididymitis and other epididymal lesions and in the assessment of underlying testicular damage in traumatic haematoceles. Ultrasound may also be useful in post-orchiectomy follow-up examinations to exclude tumour in the contralateral testis.

Chronic testicular pain following vasectomy.

The incidence of chronic testicular pain following vasectomy has not been previously assessed. We have carried out a survey by postal questionnaire and telephone interview of 172 patients 4 years after vasectomy to assess the incidence of chronic testicular pain. Significant early post-operative complications occurred in 6 patients (3.5%): 2 infection, 3 haematoma and 1 orchitis. Chronic testicular discomfort was present in 56 patients (33%), considered by 26 (15%) to be troublesome but not by the other 30 (17%). Testicular discomfort related to sexual intercourse occurred in 9 cases (5%). Of the 9 patients who had sought further medical help only 2 had had further surgery (1 an epididymectomy and 1 excision of a hydrocele). Only 3 patients regretted having had the vasectomy because of chronic pain. On ultrasound examination, epididymal cysts were a common finding on both asymptomatic and symptomatic patients following vasectomy. Prior to vasectomy, all patients should be counselled with regard to the risk of chronic testicular pain.

Acute urinary retention. Comparison of suprapubic and urethral catheterisation.

A total of 86 consecutive patients who presented to the accident and emergency department with acute urinary retention due to prostatomegaly required catheterisation; 56 received suprapubic catheters and 30 were catheterised urethrally. Both groups were followed up for 3 years. Of the 30 patients catheterised urethrally, 12 (40%) developed urinary tract infections compared with 10 (18%) urinary tract infections in the 56 patients catheterised suprapubically. Five patients (17%) in the urethral group developed urethral strictures with no strictures in the suprapubic group. Two patients catheterised urethrally developed epididymo-orchitis and 1 developed septicaemia. None of the patients with suprapubic catheters developed these complications. Furthermore, 16 patients catheterised suprapubically underwent successful trial clamping of their catheter, whereas 7 patients required recatheterisation following removal of their urethral catheters. We recommend that the use of suprapubic catheters should become the preferred initial treatment for acute urinary retention.

Effect of age, comorbidity and type of surgery on perioperative complications and mortality of prostatectomy.

OBJECTIVE: To study the effect of age, type of surgery and comorbidities (cardiovascular diseases, chronic lung diseases, diabetes mellitus and renal impairment) on the peri-operative complications and mortality of prostatectomy. PATIENTS AND METHODS: A series of 236 consecutive patients who underwent prostatectomy (171 by transurethral resection, TUR, and 65 by open procedure) were reviewed. Ninety patients at risk with one or more of the comorbidities were grouped together and compared with the remaining 146 fit patients. Also, 148 patients aged < or = 70 years were compared with 88 patients aged > 70 years. The peri-operative morbidity variables compared were haemorrhage, > or = 3 units of blood transfusion, bacteriuria, orchitis, pyrexia, uraemia and bed-stay. RESULTS: Mean post-operative bed-stay for patients at risk was significantly longer than that for fit patients (12 +/- 7 and 9.7 +/- 6 days, respectively). Mortality and the other morbidity variables, apart from post-operative bacteriuria which was more frequent in diabetics, were not significantly different between the groups. Similarly, comparing age groups revealed no significant differences. However, open surgery was associated with more haemorrhage, blood transfusion, post-operative pyrexia and a longer bed-stay. CONCLUSION: The comorbidities studied and age did not significantly influence the complications and mortality of prostatectomy. However, comorbidities prolonged post-operative bed-stay. Open surgery was associated with more bleeding and pyrexia and a longer bed-stay than TUR.

Emergency evaluation of patients presenting with acute scrotum using bedside ultrasonography.

UNLABELLED: Acute scrotal pain is not a rare emergency department (ED) complaint. Traditional reliance on medical history and physical examination can be precarious as signs and symptoms can overlap in various etiologies of acute scrotal pain. OBJECTIVE: To determine the accuracy with which emergency physicians (EPs) using bedside ultrasonography are able to evaluate patients presenting to the ED with acute scrotal pain. METHODS: The study was performed at an urban community hospital ED with a residency program and an annual census of 70,000. A retrospective chart review identified 36 patients who presented with complaints of acute scrotal pain and were evaluated by EPs using bedside ultrasound. A 5.0- or 7.5-MHz linear-array transducer with color and power Doppler capability was used to scan the scrotum. Patients were seen between July 1998 and September 1999. Diagnoses were verified by radiology or surgery. Sensitivity and specificity with 95% confidence intervals were calculated. RESULTS: The EP ultrasound examinations agreed with confirmatory studies for 35 of 36 patients, resulting in a sensitivity of 95% (95% CI = 0.78 to 0.99) and a specificity of 94% (95% CI = 0.72 to 0.99). Diagnoses included three testicular torsions, six cases of epididymitis, four cases of orchitis, one testicular fracture, three hernias, three hydroceles, and 15 normal examinations. One case of epididymitis was misdiagnosed as an epididymal mass. CONCLUSIONS: This study suggests that EPs using bedside ultrasonography are able to accurately diagnose patients presenting with acute scrotal pain. In addition, they appear able to differentiate between surgical emergencies, such as testicular torsion, and other etiologies.
