Acute disseminated encephalomyelitis: the importance of early magnetic resonance imaging

The diagnosis of acute disseminated encephalomyelitis (ADEM) is frequently missed or delayed with consequent delay in instituting therapy in the crucial phase of the illness. The role of MRI in the diagnosis of ADEM is well established, however, the value of its early utilization of treatment on the outcome of patients has not been adequately stressed. Three patients with ADEM are described. Delay in the diagnosis of the first was associated with severe sequelae, while in the other two early diagnosis and institution of corticosteroid therapy which was facilitated by MRI, was associated with a better outcome. MRI should be carried out early once the diagosis of ADEM is entertained.     

Retroperitoneoscopic approach to the adrenal glands and retroperitoneal tumours in children: where do we stand?

Choosing the best way to approach adrenal gland and retroperitoneal tumours is still difficult. We reviewed our first 10 cases operated on by retroperitoneoscopy and compared this approach with other possible ways described in the literature. There were 2 intraoperative complications: 1 opening of the diaphragm and 1 bleeding. Tumour resection was always complete. There was no conversion. There were no postoperative complications. The retroperitoneoscopic approach for adrenalectomy and retroperitoneal tumour resection is increasingly being used. In children, operation is quite fast, without much blood loss and with spectacular postoperative recovery results. Even for the right side we advocate this approach, due to the particular anatomy (small tumour size, less fat, thinner muscle layers) in this age group. Trained surgeons are, of course, mandatory.     

Transarterial embolization of vein of Galen aneurysmal malformation after unsuccessful stereotactic radiosurgery

The authors present three cases of vein of Galen aneurysmal malformations (VGAMs) diagnosed in infancy and submitted by the referring teams for stereotactic radiosurgery as the initial therapy (therapeutic doses ranging between 20–25 Gy and 40–50 Gy to the peak dose). After the conventional follow-up of 18–24 months, no change could be detected in the angioarchitecture of the lesions. All three cases were then referred for endovascular treatment and underwent embolization by the transarterial route using liquid adhesives (N-butyl cyanoacrylate). This resulted in complete anatomical exclusion of the lesion. Regardless of the theoretical efficiency of radiosurgery in the management of brain arteriovenous malformations, the present authors believe that transarterial embolization remains the treatment of choice in VGAMs. It offers a high rate of morphological cure and the best chances for normal neurocognitive development. The time required by radiosurgery to achieve a significant result is too long for developing and maturing brain and may not prevent the negative effects of the lesion, mainly in regard to hemo- and hydrodynamic disorders (atrophy, subcortical calcifications, etc.) created by the VGAM, thus leading to irreversible mental retardation.     

Influence of urbanization of the western coast of the United Arab Emirates on trace metal content in muscle and liver of wild Red-spot emperor (Lethrinus lentjan).

We hypothesized that increased ambient concentrations of metals, as a consequence of escalating urbanization and industrialization of the Gulf region will respond in increased contamination of edible fish species. In this study, we report concentrations of chromium, manganese, cobalt, copper, zinc, arsenic, cadmium, mercury and lead in meat and liver of wild Red-spot emperor (Lethrinus lentjan) from three sampling points at the UAE coast. Analysis was performed by the ICP-MS/microwave digestion. Our study has shown that meat and liver metal content was significantly higher in areas with higher industrial activity, although metal values did not exceed permitted levels of fish for human consumption.     

Health beliefs and parenting attitudes influence breastfeeding patterns among low-income African-American women.

OBJECTIVE: To describe breastfeeding initiation among 210 urban African-American mothers with inadequate prenatal care. METHODS: This study is a case-control study of postpartum mothers recruited from four large urban hospitals. RESULTS: Mothers who chose to breastfeed were more educated, employed before birth, married, and using contraception postnatally. Regression model analysis controlling for demographic differences revealed that breastfeeding was significantly associated with a higher perception of severity of illness and higher confidence in the ability of health care to prevent illness. Breastfeeding mothers were less likely to reverse parent-child roles and had a lower perception of hassle from their infant's behavior. When comparing mothers who breastfed longer than 8 weeks to those who did not breastfeed, breastfeeding mothers had high scores related to empathy toward infants on the Adult-Adolescent Parenting Inventory as well as a low perception of hassle on the Parenting Daily Hassle. The perception of existing formal or informal social support did not influence breastfeeding behavior. CONCLUSION: Personal attributes of low-income urban mothers such as health beliefs and parental attitudes may play a role in the initiation and duration of breastfeeding. Low-income African-American mothers may be influenced in their choice to breastfeed by supportive messages from physicians and nurses delivering care to mothers and their newborns. Emphasis should be placed on the role breastfeeding can play in preventing childhood illnesses.     

Congenital anomalies among infants of diabetic mothers: a study of 466 cases at King Fahd Hospital of the University, Al-Khobar.

The purpose of the study was to determine the incidence of congenital anomalies among infants of diabetic mothers and compare this with the normal obstetric population in our hospital. Among 17 463 patients delivered at the King Fahd Hospital of the University, Al-Khobar, Saudi Arabia between January 1987 and December 1992 there were 466 diabetic mothers who delivered 466 singleton births. The incidence of diabetes was 2.6%. Among those 466 diabetic patients there were 132 with clinical diabetes which was present before pregnancy and which required insulin treatment during pregnancy and 334 with gestational diabetes. There were 14 lethal congenital anomalies among the infants of diabetic mothers (3%) compared with 69 anomalies in general obstetric population (0.4%). The difference = was very highly significant P = 0.001. Ten anomalies were responsible for 10 stillbirths and the other four anomalies resulted in four neonatal deaths. The most common anomalies were those of the central nervous system and multiple fetal anomalies, followed by cardiovascular system, renal and chromosomal anomalies. All those anomalies occurred in the infants whose mothers had clinical diabetes.     

Invasive cancer of the prostate. Reconstruction of the lower urinary tract by prostatic resection and ureteral reimplantation into the bladder vault

Some prostatic cancers (T4) spread out along the ureters to the kidneys. Patients, usually arrive with terminal renal failure and bladder retention and have often fast-advancing cancer with massive nodes invading. T.U.R., reimplantation of the ureters into the bladder dome or into a pso?c bladder and the specific treatment of the cancer, have often permitted these patients to survive for some years without any dialysis. In these cases we often find very important lower limbs oedema. With lymphatic nodes radiotherapy and subcutaneous injections of heparin, these oedema may regress completely.     

Testicular torsion: Evaluation of contralateral testicular histology

Infertility may occur in patients with unilateral testicular torsion whose contralateral testis is intact. Depending on this observation, the physicians have begun to examine the contralateral testis. In the present prospective study we aimed to examine the histopathologic alterations occurring in the contralateral testicle with time. Sixty adult male albino rats were included in the programme, and following experimental torsion the histopathologic findings, especially those in the contralateral testis, were evaluated after 4–12 weeks. Long-term and high degree torsion of the testicle led to varying degrees of deterioration in the germinal epithelium and interstitial cells of the contralateral testicle. Histopathologic alterations were reversed in 12 weeks. Tubular diameter and testicular volume also decreased in accordance with the histopathologic alteration. In our opinion, orchiectomy following torsion of one testicle will limit potential histopathologic alterations in the contralateral testicle.
