Ascaris Lumbricoides Infestation (ALI) is one of the most common helmintic disease of the gastrointestinal tract, and may cause severe surgical complications, especially in children. ALI is frequent in tropical and subtropical countries. We present our experience with a case of a 5-years old pakistan girl treated in Italy for acute abdomen in which ALI was detected during surgical exploration.

Pheochromocytoma is a catecholamine-producing tumor of the sympathetic nervous system which in 4-14% of the cases may be malignant. The differentiation between benign and malignant phoechromocytomas is very difficult, the presence of metastatic lesions and gross invasion into surrounding tissues are the lonely accettable parameters to confirm malignancy. Since the patients with malignant pheochromocytomas have a very poor survival rate, care must be taken for an early detections and a careful follow up. Three cases of malignant pheochromocytoma are reported. In one of these cases the tumor was a functioning mass; the other two cases presented by a hemorrhagic complication. A careful review of the pertinent literature allows to outline the correct approach to this rare pathology as for the diagnosis and the treatment, also including the actual criteria to establish its malignancy.

A careful review of the available literature on the clinical and pathologic features of the so-called inflammatory aneurysm of the abdominal aorta is reported. The etiology of this peculiar disease is still obscure and controversial, even if the current trend is to define it as an immunomediate phenomenon consisting on an "exaggerated" inflammatory response to atherosclerosis. Suggestions about the similarity or identity from the pathologic viewpoint, of inflammatory aneurysm, periaortic fibrosis and idiopathic retroperitoneal fibrosis are attractive, but not universally accepted. The surgical treatment aims at the same objectives than for atherosclerotic aneurysms (i.e. prevention of rupture); operative management is however endangered by greater difficulties which hopefully may be reduced in the coming years by the use of corticosteroids and mainly through the wider application of endografting procedures.

The Authors report their experience in the treatment of inflammatory aneurysm, on a whole of 355 patients consecutively operated on for abdominal aortic aneurysm. The incidence was 5.6% when relying on clinical aspects; 10.6% when considering the results of microscopy. All patients were operated on through a retroperitoneal approach: early and late results of surgery were not significantly different between the two groups of patients (inflammatory aneurysm 38, atherosclerotic aneurysm 317).

The authors report a case of giant cavernous hemangioma of the liver, almost entirely extrahepatic, bulging from the inferior surface of the right lobe into the abdomen, treated surgically on account of worsening symptoms referable to continuing growth. A thorough search of the literature allows a critical review of the surgical indication in this benign pathology, rarely complicated by significant clinical events. Surgery is indicated, in lack of relevant complications, only when significant symptoms, continuing or worsening, are undoubtedly referable to the presence of the angioma.

It is well known that vertebral schisis is frequent in enuretic children but the true incidence in the normal population is not clear, because all series published are referred to children with associated urinary anomalies, who were submitted to voiding cystography and or intravenous pyelography. This determine a statistical bias. The aim of our study was to compare the prevalence of vertebral schisis in enuretic children and in the general pediatric population. Therefore, we chose 142 enuretic children without associated urological or neurological anomalies and a control group of 152 children, assumed as general population, who were submitted to spinal X-rays during screening for scoliosis or congenital dysplasia of the hip. Vertebral schisis was found in 65% (93/142) of enuretics and in 18% (28/152) of control group children. Maximum association between enuresis and vertebral schisis was found in primary monosymptomatic nocturnal enuresis (82%), while minimum association was found in children with secondary enuresis (57%). The difference in percentage of association enuresis-schisis was statistically significant between enuretics and control group and between primary monosymptomatic and secondary enuresis (p < 0.001). The results of this paper are simply add knowledges on the prevalence of the sacral schisis in enuretic children. But, to speculate the different prevalence in different types of enuresis, the results should confirm that the phenomenon of enuresis is multifactorial and the primary monosymptomatic and secondary enuresis have different etiological factor.

Total Sacral Agenesis (TSA) is a rare congenital anomaly of the lower vertebral column, frequently associated with bladder dysfunction. The diagnosis is often delayed until the evidence of neurological disorders addresses at neuro-radiological examination. In the last 9 years we observed 7 children, 3 males and 4 females, with TSA. The average age at diagnosis was 8 years (range: 1-15 years). Maternal diabetes was present only in one case. In 5 patients, urological ones have been the symptoms of presentation. In one case, TSA has been discovered because of the presence of a sacral mass (lipoma) and the subsequent development of club-foot. The neurological screening, performed in all patients with anorectal anomalies, led to the diagnosis of total sacral agenesis in a child with anteriorized anus. All patients have been evaluated by means of Magnetic Resonance Imaging, renal ultrasound, voiding cystography, renal nuclear scan and urodynamics. The functional evaluation of the lower urinary tract has shown a pattern of neurogenic bladder dysfunction in all children, while bilateral vesico-ureteral reflux has been detected in 2 cases. Intermittent clean catheterization (ICC) has been instituted at the diagnosis in all children. Surgery for continence and protection of upper urinary tract (bladder augmentation and bilateral ureteral reimplantation) has been performed in one patient. At a medium follow-up of 3 years (range: 1-5 years) 2 patients have been lost, normal renal function and urinary continence have been achieved in 4 and one child is continent but has renal failure. An early diagnosis and a correct neuro-urological evaluation and treatment are necessary to prevent urinary tract damage and achieve urinary continence in these patients. Symptoms, clinical findings and relationship with maternal diabetes are discussed. The diagnosis can be enough early if physicians pay attention to maternal diabetes, subtle neurological symptoms (voiding disturbance, constipation, club-foot) and careful physical examination of the back.

The authors report their experience in the treatment of the chronic constipation in paediatric age. During the last 3 years (1991-1994), 230 children presenting chronic constipation have been studied at the Strumental Gastroenterologic Department of Children Hospital Bambino Gesù; 19 of them (8%), 10 male and 9 female, were studied with anorectal manometry, defecography and Intestinal Transit test. All the patients had a overtone (high squeeze) of the anal sphincter and the medical treatment was unsuccessful. They underwent sphincteromyectomy by posterior approach. In 17 patients it has been obtained a notable improvement of the symptomatology with regularization of the evacuations. The simplicity of the surgical technique, the absence of complications and the obtained results confirm the validity of sphinteromyectomy in the therapy of the chronic constipation in paediatric age. Interoperating anorectal manometry proved to be essential both in modulating sphincteromyectomy and in its eventual complications.

Considering the clinical and statistical data about injured children coming to the emergency department in the years between 1990 and 1995, the Authors hope better information, identification of risks, use of safety devices in order to successfully implement precautionary measures and the assistance in accidents which still are the first reason for death in children.

Authors report on their experience about ceftriaxone in surgical prophylaxis in childhood. 30 patients have been treated, suffering from surgical diseases, either thoracic or abdominal ones, including malignancies. Ceftriaxone was administered once a day; patients received ceftriaxone only once preoperatively: Results have been very satisfactory, the only two complications having been found in two severely immunocompromised patients.

A long-term administration of Indobufen, 400 mg daily, was evaluated in 57 patients with cardiovascular diseases. Aggregation waves induced by ADP, collagen and epinephrine showed a significant and persistent inhibition of platelet function. Minor side effects were observed and in 6 patients the drug was withdrawn: 4 patients began to experience gastric troubles, 1 patient had positive occult test for blood, 1 patient developed an allergic rush. Clinical evaluation and platelet aggregation study before starting indobufen and during the follow up period seem to be useful in the evaluation of effectiveness, safety, compliance and suitable daily dose.
