Autoimmune cholangitis can be associated with other autoimmune disorders. The case is described of a 58-ear-old female who developed severe microcytic anaemia resistant to oral iron treatment. Evaluation of the patient led to the diagnosis of coeliac disease, a rarely described association. Gluten-free diet and treatment with oral haematinics led to reversal of the anaemia.
BACKGROUND: To evaluate the frequency of ovarian cyst formation in the adolescents and to report on the clinical implications of these cysts. METHODS: A prospective analysis of data on 94 girls (aged 10-19) with diagnosed ovarian cysts was performed at the Gynecology Department of Aversa and Naples hospitals between 1995-2000. Operations were performed because of pains or ultrasound suspected features. The patients who were not operated on were kept under observation and had ultrasound tests monthly, receiving gestogen to facilitate resolution of the cyst and as treatment of menstrual disorders. The site, number, size and type of the cysts were examined. RESULTS: The ovarian cysts were unilateral, unilocular, and simple, with the size varying between 3 cm and 5 cm in 83 cases, more than 5 cm in 8 cases and less than 3 cm in 3 cases. Among 94 patients 6 (6.4%) were initially qualified for the operation because of the strong pains or ultrasound equivocal aspect. Hormonal treatment was given in 74 cases, whereas in 14 cases only follow up sonography was performed. Cysts resolved spontaneously in 2 months on average, or in 1 month after hormonal treatment. No malignant tumors were found in the observed group. CONCLUSIONS: Clinical observation periodically repeated ultrasound tests seems to be the most appropriate procedure employed at adolescent girls with asymptomatic ovarian cysts. Hormonal treatment shortened the duration of the cysts somewhat, even if in a not significant manner, and thus was useful mainly in the treatment of concomitant menstrual disorders.

BACKGROUND: To evaluate the clinical features, the surgical management and outcome of 20 patients with stage-I borderline ovarian tumors. METHODS: Twenty cases of FIGO stage-I ovarian tumors, aged from 31 to 58 years (mean 37 years) have been reviewed. All informations of clinical stage, surgical intervention and prognosis were achieved by reviewing hospital records. Minimal requirements for conservative management were adequate staging and complete information about the therapeutic options. Factors important in the choice of the treatment were, age, wish to preserve fertility, histologic type and grade, and the stage of the tumour. RESULTS: Eleven of the 20 patients (55%) were at stage IA, 6 cases (30%) were at stage IB, 3 cases (15%) were at stage IC. Thirteen (65%) were with mucinous cystadenoma of borderline malignancy, 7 cases (35%) were of serous type. Thirteen patients underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH and BSO). Seven patients were treated with unilateral oophorectomy or unilateral salpingo-oophorectomy (USO). One patient underwent enucleation of ovarian tumor and biopsy of contralateral ovary. Any patient were treated with chemotherapy after operation. With a median follow up of two years, we observed no recurrence of carcinoma in women treated conservatively or in those treated more radically. CONCLUSIONS: Conservative surgery remains a therapeutic option in selected patients with borderline ovarian tumors. Prolonged intensive follow-up is required for women treated conservatively for borderline malignant ovarian tumours.
We report a case of male breast metastasis from a urothelial carcinoma. Only two cases of this type of metastasis have been previously reported, and these were in the female breast. Clinical examination showed a progressive swelling of the left mammary region, with periareolar skin infiltration. Both mammography and ultrasound showed a rounded mass. Only histological examination with immunohistochemical staining permitted the correct diagnosis to be made. A particular feature of the present case is the absence of contralateral gynaecomastia, normally seen in cases of metastatic tumour to the breast from prostatic carcinoma.

With a varied presentation and a difficult preoperative diagnosis, schwannoma accounts for only a small percentage of retroperitoneal tumors. Moreover, malignant schwannoma of the adrenal gland, kidney and renal pelvis has previously been described. We report the first case of benign schwannoma causing obstruction by external compression of the ureteropelvic junction. A case report of a male patient who complained of a 3-month history of dull lumbar pain on the right side is reported. Using intravenous pyelogram, sonography and computed tomography a benign tumor of the retroperitoneum was suspected. Upon exploration, the suspected diagnosis of the tumor's retroperitoneal origin was confirmed. After the histological and immunohistochemical studies the diagnosis was verified. The diagnosis, treatment and histological features of benign schwannoma are discussed. A brief review of the literature is also included.
In 1945, Lennox was the first to describe the epileptic states mainly expressed by various degrees of consciousness disturbance, which have their onset in children who present epileptic absences correlated with ictal EEG patterns of spike-wave complex discharges at about 3 Hz. As the clinical picture seemed to be similar to an uninterrupted series of absences, this led to the definition "Petit Mal Status" (PMS). Many authors have subsequently reported that PMS can occur in epileptic subjects who have never presented absences (and even in subjects without a previous history of epilepsy) and that the related EEG pictures were characterised by paroxysmal generalized activity of various morphology, but hardly ever consisted of the continuous rhythmic spike-wave or polyspike-wave complexes at 3 Hz found in petit mal absences. Finally, in reporting the onset and recurrence of this condition typically in adults and the elderly, some authors have proposed the existence of a particular form of PMS (dependent on different types of pathologic factors and characterising a specific syndrome of this age) that is different from that of the "real PMS" typical of childhood and related to petit mal absences. This paper describes fifteen patients in whom the onset of the condition occurred at different ages, and who seem to exemplify the various possible clinical expressions of PMS, with the aim of making a contribution towards the better nosographic definition of this epileptic condition. On the basis of our study, we sustain that the so-called PMS is a seizure type of Idiopathic Generalized Epilepsy which may appear at nearly all ages, and may occur in isolation or in association with other epileptic manifestations, but cannot itself be considered as characterising one or more age-dependent syndromes.
Language lateralization was assessed with a dual task procedure in 10 male right-handed patients with Down's Syndrome and relatively preserved linguistic skills. Their performance was compared with that of two control groups, with and without mental retardation, matched with Down's Syndrome individuals for sex, handedness and I.Q. Results did not support the hypothesis that mental retardation is related to specific pattern of cerebral lateralization.
Rolandic paroxysmal epilepsy (RPE) is a useful model for investigating the complex links between epilepsy and cognitive dysfunction. 44 children with RPE who met the following (among other) criteria: negative CT scan, freedom from drug treatment, and IQ greater than or equal to 80, were assigned to three subgroups by side of EEG focus: left, right and bilateral. A neuropsychological battery elicited small differences in cognitive performance between the whole group and the controls and among the subgroups, only partially correlated with EEG side. A follow-up assessment showed that the short falls had disappeared along with the seizures and EEG anomalies, thus confirming the benign nature of RPE. Our findings suggest too that the mere presence of paroxysmal cortical activity is enough to trigger cognitive dysfunction.
The neurotoxicity of interferon-beta (IFN-beta) was assessed by performing electrophysiological examinations and neuropsychological tests on 22 patients with malignant hematological diseases before, during, and after IFN-beta treatment. IFN-beta (6 x 10(6) IU/m2) was infused i.v. for 6 h daily for 7 days on alternate weeks for a total of three cycles (induction therapy) and was then continued at the same dose, twice a week, for an additional 24 weeks (maintenance therapy). Twenty-one of the 22 patients were evaluable. There were no significant changes in EEGs, visual evoked potentials, sensory conduction central time or motor nerve conduction velocity of two long nerves in the 15-19 patients studied before and after induction therapy, nor in the 6-8 patients investigated at the end of maintenance therapy. Neuropsychological monitoring failed to disclose any IFN-induced deterioration in 21 patients tested before and at the end of induction therapy or in the 10 patients who were also studied at the end of maintenance therapy. Despite certain limitations in the patient follow-up, the results underline the good general tolerance of IFN-beta.
The purpose of this longitudinal study was to investigate if the presence of frontal motor deficits in parkinsonians without signs of global intellectual impairment may have a predictive value for the development of a progressive dementing process during the course of the illness. An examination of the higher level of motor organization, using skills thought to depend upon the integrity of the frontal regions, was performed by 30 parkinsonian patients who did not present any signs of general intellectual impairment. According to their performance, as compared with controls, they were divided into two subgroups: those with and those without frontal dysfunctions. After a mean period of 4 years, a second neuropsychological examination was carried out to assess any eventual change of mental status. The results suggest that frontal dysfunctions may be observed several years before the appearance of generalized intellectual impairment and may be considered one of the predictive factors for development of dementia in Parkinson's disease. Careful consideration of these defects during examination of motor abilities may be of value in the clinical management of parkinsonian patients.
A bilateral ovarian sex-cord tumor with annular tubules (SCTAT) was incidentally discovered in an amenorrheic patient with Peutz-Jeghers syndrome during conservative surgery in which a small non-capsulated mass was removed from each ovary. Ovulation was then induced over two consecutive cycles with urinary gonadotropins; the couple did not conceive because of a male infertility factor. Hysterectomy and bilateral oophorectomy were performed to prevent recurrence and avoid the possibility of a cervical malignant adenoma. Immunohistochemistry of the SCTAT showed positivity for estradiol and testosterone similar to that of Sertoli and granulosa cell tumors; progesterone was not detected in any cellular component of the neoplasia. Electron microscopy showed that the neoplasm consisted of numerous solid cords of cells surrounded by fibrillary layers of basal lamina, as well as central hyaline bodies. Two types of cells, clear and dark, were noted; clear cells were predominant and intermixed with scattered dark cells. No crystalloids or Charchot-Bottcher filaments were detectable in the tumors.
