Abstract
PURPOSE: To characterise the nature and degree of ocular disorders and cerebral morphological and functional abnormalities in a population-based group of visually impaired full-term pre-school children. METHODS: Forty-five children who were born at full-term between 1989 and 1995 in Värmland, Sweden, were reported as being visually impaired. An ophthalmological examination was performed and clinical data regarding mental development and neurological disease were obtained for all children. Cerebral imaging was performed in 35 children. RESULTS: Twenty-six per cent of the children were found to have ocular disorders only. Forty-two per cent had cerebral morphological abnormalities, verified by cerebral imaging, and 65% had signs of cerebral functional abnormalities. In total, 74% were found to have cerebral morphological and/or cerebral functional abnormalities. CONCLUSION: The majority of children with visual impairment, including children with ocular disorders, were found to have cerebral morphological and/or cerebral functional abnormalities. We suggest that any child with visual impairment should therefore undergo cerebral imaging and be examined by a paediatrician in order to establish the correct diagnosis.

Abstract
To find predictors of abnormal retinal vascularisation in moderately to late preterm newborn infants considered to have no risk of developing retinopathy of prematurity.
Seventy-eight infants (34 girls) were recruited from a longitudinal study of otherwise healthy premature children born at a gestational age of 32 + 0-36 + 6 weeks. Retinal vessel morphology was evaluated at mean postnatal age 7 days. Insulin-like growth factor-I (IGF-I) levels were analysed in umbilical cord blood.
Of the 78 infants, 21 (27%) had abnormal retinal vessel morphology; they had significantly lower median (range) birth weight [1850 g, (1190-3260), vs. 2320, (1330-3580), p

Abstract
Prostate cancer is the most common cancer among men in many countries. The aim of the present study was to find out how the symptoms leading to a diagnosis, diagnostic procedures and stages of the disease among prostate cancer patients have changed over a period of 20 years.
This retrospective chart review consisted of 421 prostate cancer patients whose treatment was started in the years 1982, 1987, 1992, 1997 and 2002 at the Oulu University Hospital. Earlier prostatic disorders, specific urological symptoms, diagnostic procedures, the TNM classification and histological grade were recorded.
The number of symptom-free prostate cancer patients increased over the 20 years, as did the number of men suffering from chronic prostatitis, although the latter increase was not statistically significant. A drop in the number of clinical T4 cases and increase of clinical T1 and clinical T2 cases was recorded but no clear change in the histological distribution occurred. The 5-year prostate cancer-specific survival improved significantly over the 20 years. The urologist was found to be the person who was contacted first most often.
Our data indicate that the number of prostate cancer patients has increased hugely over the period from 1982 to 2002 and although the clinical T stage has moved towards earlier stages, the proportion of well differentiated cancers remains low, so that most patients have clinically significant cancer with the need of some form of therapy. Further, prostate cancer-specific survival improved significantly over the period.

Abstract
PURPOSE: The purpose of this study was to characterize the clinical and morphologic spectrum of all children referred for optic nerve hypoplasia to a tertiary referral hospital in Sweden during a 9-year period. SUBJECTS AND METHODS: A retrospective review was undertaken of the charts of 117 children (age range, 0.25-16 years), treated at the Children's Hospital, Göteberg between 1988 and 1996, after the diagnosis of optic nerve hypoplasia. Ocular fundus morphologic condition was evaluated by digital image analysis of fundus photographs in 50 children, and neuroimaging was performed in 57 children. RESULTS: Of the 117 children with optic nerve hypoplasia, 66 (56%) were boys and 51 (44%) were girls. Preterm birth occurred in 24 (20%), and 14 (12%) were born small for gestational age. Additional diagnoses, such as fetal alcohol syndrome, septo-optic dysplasia, perinatal adverse events, and neuropsychiatric disorders, were made in 88%; 7% had unilateral optic nerve hypoplasia. Most of the children had small optic disc, cup, and neuroretinal rim areas, as well as retinal vascular abnormalities; 75% were visually impaired, and a high incidence of nystagmus and strabismus was found among these children. CONCLUSION: This study indicates that optic nerve hypoplasia has a wide clinical and morphologic spectrum and is associated with a broad range of disorders of the central nervous system. It is suggested that differences in the etiology and timing of the lesion as well as associated lesions may explain this spectrum of optic nerve hypoplasia in children.

Abstract
To examine differences in growth patterns in preterm infants developing major morbidities including retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), necrotising enterocolitis (NEC) and intraventricular haemorrhage (IVH).
Cohort study of 2521 infants born at a gestational age (GA) of 23-30 weeks from 11 level III neonatal intensive care units in USA and Canada, and 3 Swedish population-based cohorts.
Birth weight and postnatal weight gain were examined relative to birth GA and ROP, BPD, NEC and IVH development.
Among infants with a birth GA of 25-30 weeks, birth weight SD score and postnatal weight were lower in those developing ROP and BPD. Infants developing ROP showed lower growth rates during postnatal weeks 7-9 in the 23-24 weeks GA group, during weeks 4-6 in the 25-26 weeks GA group and during weeks 1-5 in the 27-30 weeks GA group. Infants with BPD born at 27-30 weeks GA showed lower growth rates during postnatal weeks 3-5. Infants with NEC had lower growth rates after postnatal week 6 in all GA groups, with no significant differences in birth weight SD score. IVH was not associated with prenatal or postnatal growth.
In this cohort study of extremely preterm infants, we found that the postnatal growth pattern was associated with morbidities such as ROP, BPD and NEC as well as with gestational age at birth.

Abstract
A series of 73 patients with bladder outflow obstruction caused by benign prostatic hyperplasia underwent urodynamic investigation, including the cold water test. The presence of detrusor instability was associated with a higher urethral opening pressure, maximum detrusor pressure and detrusor pressure at maximum flow. Instability was more common and more pronounced in patients with a lack of cold sensation, but there were some patients who, whilst lacking cold sensation, still possessed the cold reflex. This suggests partial denervation of the bladder or some form of altered modulation of sensory activity within the spinal cord or central nervous system. On the other hand, some of the patients lacked cold sensation but showed a stable detrusor and a high maximum cystometric capacity. This leads to the conclusion that there are different mechanisms by which the bladder reacts to outflow obstruction.

Abstract
Cysts of the tunica albuginea have been considered very rare. Their clinical significance lies in their presentation as discrete testicular masses often diagnosed as malignancies prior to removal. We report our experience with 6 cases of cysts of the tunica albuginea over a 12-year period and review the relevant literature. It is obvious that these cysts can be both of epithelial and of mesothelial origin. Our material includes a cyst lined by a transitional-like epithelium, of a kind to our knowledge not reported previously. All of the cysts were found by palpation and they constituted 6% of the testicular tumours examined over the same period. High-resolution ultrasound examination can distinguish them from solid testicular masses, as in 2 cases here, thus enabling unnecessary operations to be avoided.

Abstract
Twenty cases of adenocarcinoma of the urinary bladder were diagnosed and treated at Oulu University Hospital between 1978 and 1991, comprising nine primary adenocarcinomas (three urachal and six non-urachal) and 11 of extravesical origin (six from the colon, four from the prostate and one from the perineal skin). The prognosis for primary adenocarcinoma after radical surgery was relatively favourable during a follow-up of mean 54 months, but extravesical origin carried a high mortality rate. The diagnostic and therapeutic aspects are discussed.

Abstract
A total of 285 renal units in 248 patients received 424 extracorporeal shock wave lithotripsy (ESWL) treatments with mobile lithotriptors for renal and ureteric stones at Oulu University Hospital. Treatments were given approximately once a month (1-2 days) with 7-10 treatments per day. The overall success at 1-3 months was 88% (74% stone-free). Success with single renal stones was 88% (70% stone-free), that with multiple renal stones 78% (62% stone-free) and that with ureteric stones 93% (89% stone-free). Retrograde manipulation appeared to be a safe and effective treatment for patients with obstructing ureteric stones obliged to wait for the next treatment session. The most serious complication was one perirenal haematoma requiring transfusion. The results compare favourably with those achieved with fixed lithotriptors and prove that mobile lithotriptors are suitable for small centres.

Abstract
BACKGROUND. The eye is a sensitive indicator of adverse effects of prenatal alcohol exposure. Anomalies of the eyes and their adnexa are known to be associated with the fetal alcohol syndrome (FAS), although long-term effects of these malformations are unknown. DESIGN. A prospective ophthalmologic follow-up (median, 11 years; range, 4 to 19 years) was performed in 25 children with FAS. Their social situation and educational status were also investigated. RESULTS. All but one of the children had ophthalmologic abnormalities. Fundus anomalies were observed in 23 children, of whom 19 had optic nerve hypoplasia. Thirteen children had concomitant strabismus. Microphthalmos, buphthalmos, phthisis, microcornea, coloboma of the iris and uvea, blepharoptosis, cataract, persistent hyperplastic primary vitreous, and nystagmus were observed in single cases. The dysmorphology of the eyes remained unchanged during the follow-up period. In 2 children with severe mental retardation and, initially, very poor vision, the severe visual handicap persisted. Seventeen children had an initial visual activity > or = 20/70, which remained unchanged in 10 children and improved in 7 children, despite the presence of optic nerve hypoplasia in 14 of the children. Ten mothers died, 8 of them because of alcohol-related diseases, and only 4 of the mothers were able to take care of their children. Sixteen children went to schools for the mentally retarded, and only 3 children had a normal school education without extra teaching assistance. CONCLUSIONS. In children with FAS, the major sequela, ie, brain, damage, remains despite extensive medical, educational, and social support. The presence of ophthalmic signs, which persisted but did not deteriorate during the follow-up period, strengthens the diagnosis of FAS, and the high frequency of ocular involvement indicates the importance of a complete ophthalmologic evaluation in children with FAS.
