Brain morphometry of preschool age children affected by autism spectrum disorder: Correlation with clinical findings.

The aim of our study was to use a combined imaging and clinical approach to identify possible patterns of clinical and imaging findings in a cohort of preschool age autism spectrum disorder (ASD) patients. In order to identify imaging patterns that could be related to specific clinical features, a selected group of ASD patients (age range 3-6 years) without dysmorphic features, epilepsy or other major neurological signs, malformations or other lesions at MRI was subjected to brain volumetric analysis using semiautomatic brain segmentation. An age-matched group of typically developing children was subjected to the same analysis. Our results were consistent with previous literature: Total gray matter volume, total cortical gray matter volume and amygdalar volumes were significantly greater in the ASD group than the control group. When we divided the study group into subgroups on the basis of clinical findings such as high- or low-functioning, or verbal and nonverbal, the only significant difference between verbal and nonverbal subjects was in cerebellar hemispheric size. In conclusions, our results confirm that newer brain MRI techniques using semiautomatic brain segmentation can provide information useful for defining the differences between ASD patients and controls, particularly if they form part of an integrated approach between MRI and cognitive-behavioral and genetic data.

Epilepsy, unawareness of seizures and driving license: the potential role of 24-hour ambulatory EEG in defining seizure freedom.

INTRODUCTION: Seizures represent a potential source of accidents/death. Permission to drive may, therefore, be granted in a seizure-free period. Laws and regulations regarding this issue vary widely, and the onus of reporting seizures ultimately rests on the individual. Unfortunately, as some patients are unaware of their seizures, their reports may be unreliable. METHODS: In this retrospective study, we selected, from a group of 1100 consecutive patients, 57 cases (26 males/31 females; mean age: 42.5 years) in whom the AEEG documented ictal events (UIEs) not reported in a self-kept diary. By means of a simple questionnaire, we interviewed all these patients to collect information on driving licenses. We, thus, assessed how many of these patients (both drug resistant and seizure free) drove regularly. RESULTS: Our study shows a relatively large number of patients with epilepsy and UIEs. Fifteen patients suffered from idiopathic generalized epilepsy (IGE) while 42 had partial epilepsy (PE). The patients were seizure free in 21 cases and 36 had drug-resistant seizures. Many patients in both these subgroups had a driving license and drove normally (active driving in 12/36 drug-resistant patients and in 18/21 seizure-free patients). Worthy of note is the finding that an "apparently" seizure-free group of patients drove regularly. CONCLUSIONS: This study revealed a large number of patients (both drug resistant and seizure free) with AEEG-documented UIEs. This finding highlights the usefulness of AEEG in clinical practice as a means of more accurately ascertaining seizure freedom and supporting decisions involving the renewal or granting of a driving license.

Recurrent partial seizures with ictal yawning as atypical presentation of Hashimoto's encephalopathy (steroid-responsive encephalopathy associated with autoimmune thyroiditis).

Hashimoto's encephalopathy (HE), also known as steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), is a rare condition whose pathogenesis is unknown, though autoimmune-mediated mechanisms are thought to be involved. The prevalent neurological manifestations of this disorder are epileptic seizures and psychocognitive disorders associated with EEG alterations. High anti-thyroid antibody titers (particularly in cerebrospinal fluid) and the effectiveness of steroid therapy are usually considered to be crucial elements in the diagnostic process. We describe a 19-year-old female patient who had been referred to the psychiatric unit because of behavioral disorders characterized predominantly by delirium with sexual content. She developed recurrent focal seizures characterized by atypical ictal semiology (repetitive forceful yawning) and a rare EEG pattern (recurrent seizures arising from the left temporal region without evident "encephalopathic" activity). The presence of anti-thyroperoxidase antibodies in her cerebrospinal fluid and a good response to steroids confirmed the diagnosis of HE. The atypical presentation in the case we describe appears to widen the electroclinical spectrum of HE and highlights its importance for differential diagnosis purposes in the neuropsychiatric setting.

Intravenous Levetiracetam as first-line treatment of status epilepticus in the elderly.

BACKGROUND: Status epilepticus is a condition of prolonged/repetitive seizures that often occurs in the elderly. Treatment in the elderly can be complicated by serious side effects associated with traditional drugs. OBJECTIVE: The aim of this pilot study was to evaluate the short-term efficacy/safety of intravenously administered LEV (IVLEV) as the treatment of choice for SE in the elderly. METHODS: We enrolled nine elderly patients (five female/four male; median age 78 years) with SE. Two patients had a previous diagnosis of epilepsy; in the remaining seven, SE was symptomatic. SE was convulsive in five and non-convulsive in four. All the patients presented concomitant medical conditions (arrhythmias/respiratory distress/hepatic diseases). As the traditional therapy for SE was considered unsafe, IVLEV was used as first-line therapy (loading dose of 1500 mg/100 ml/15 min, mean maintenance daily dose of 2500 mg/24 h) administered during video-EEG monitoring. RESULTS/CONCLUSIONS: In all the patients but one, IVLEV was effective in the treatment of SE and determined either the disappearance of (7/8), or significant reduction in (1/8), epileptic activity; no patient relapsed in the subsequent 24 h. No adverse events or changes in the ECG/laboratory parameters were observed. These data suggest that IVLEV may be an effective/safe treatment for SE in the elderly.

Oxaliplatin plus irinotecan and leucovorin-modulated 5-fluorouracil triplet regimen every other week: a dose-finding study in patients with advanced gastrointestinal malignancies.

BACKGROUND: Oxaliplatin (OXA) and irinotecan (IRI) are active drugs in first-line as well as second-line treatment of advanced colorectal cancer patients, their toxicity profiles are not overlapping, and both drugs have shown synergism with folinic acid-modulated 5-fluorouracil (5-FU). We planned this phase I study to define the dose-limiting toxicities (DLTs), the maximum tolerated doses (MTDs), and the recommended doses (RDs) for a triplet regimen including OXA plus IRI on day 1, and 6S-folinic acid (LFA) plus 5-FU on day 2, every 2 weeks. PATIENTS AND METHODS: At least three patients had to be treated at each dose level, and the trial proceeded if no more than 33% of patients showed a DLT after the first cycle. Starting from OXA 85 mg/m(2) (over 2 h) and IRI 150 mg/m(2) (over 1 h), an alternated escalation was planned up to 110 mg/m(2) and 200 mg/m(2), respectively. Thereafter, a fixed dose of LFA, 250 mg/m(2) (as 2-h infusion), plus an escalating dose of 5-FU (from 650 to 800 mg/m(2) as an intravenous bolus) was added on day 2 to the previous dose level of OXA and IRI. RESULTS: Forty-six patients, all but four affected by advanced colorectal primaries, entered this study. The MTDs for OXA and IRI given on the same day were 110 and 200 mg/m(2): these doses caused a DLT in three of six patients. The previous dose level (110 and 175 mg/m(2), respectively) on day 1 was safely followed on day 2 by LFA plus 5-FU up to 800 mg/m(2). Indeed, only one of three patients treated at this last level had a DLT. This cohort was then expanded including a total of 14 patients, and on the whole series five cases of DLT occurred: WHO grade 4 neutropenia (two patients), grade 3 or 4 diarrhoea (three patients). Cumulative toxicity was analysed in 43 patients for a total of 347 cycles: grade 4 neutropenia was detected in 13 patients (30%); it was not dose-related, nor was it exacerbated by the addition of modulated 5-FU. Febrile neutropenia occurred in four patients. Grade 3 or 4 diarrhoea was suffered by nine (21%) and five (12%) patients, respectively. Two complete and nine partial responses were reported on 40 evaluable patients (six patients were disease-free at study entry), giving a response rate of 27.5% (95% confidence interval 15% to 44%); nine of 18 (50%) assessable patients of the two last cohorts treated with the triplet regimen achieved a complete response (two patients) or a partial response (seven patients). CONCLUSIONS: The RDs for this biweekly regimen were: OXA 110 mg/m(2) plus IRI 175 mg/m(2) on day 1, and LFA 250 mg/m(2) plus 5-FU 800 mg/m(2) on day 2. This regimen appeared active in pretreated gastrointestinal malignancies, and it is worthy of being evaluated in advanced colorectal carcinoma after failure of 5-FU-based adjuvant or palliative treatment.

Cisplatin-epirubicin-paclitaxel weekly administration with G-CSF support in advanced breast cancer. A Southern Italy Cooperative Oncology Group (SICOG) phase II study.

PURPOSE: It has been shown in vitro that both cisplatin and epirubicin increase the antitumor activity of paclitaxel. Weekly administration could give a substantial improvement in the therapeutic index of cisplatin and paclitaxel. This study was aimed at defining the antitumor activity of a weekly cisplatin-epirubicin-paclitaxel (PET) administration in locally advanced or metastatic breast cancer patients. PATIENTS AND METHODS: Sixty-eight breast cancer patients with advanced disease, who had not received prior chemotherapy (except adjuvant), received weekly cisplatin 30 mg/sqm, paclitaxel 120 mg/sqm and epirubicin 50 mg/sqm plus G-CSF (day 3-5), for a maximum of 12 cycles. Thirty-five patients had stage IIIB and 33 stage IV disease (14 with visceral metastases). RESULTS: All patients were evaluable for response on an intent to treat basis. Overall, 21 complete and 38 partial responses have been recorded for an 87% ORR (95% CI = 76-94%). Fourteen CRs and 19 PRs have been registered in the 35 patients with locally advanced disease for a 94% ORR (95% CI = 81-99%) while 7 CRs and 19 PRs were observed in the 33 patients with metastatic disease for a 79% ORR (95% CI-61-91%). Surgery was performed in 33/35 women with locally advanced disease. Four of these patients (11%) showed no invasive cancer on pathologic examination, and in an additional 8 patients tumor < 1 cm was found in the breast. Only 4/33 patients who underwent surgery relapsed. The projected one-year RFS was greater than 80%. At an 11-month median follow-up (range, 3-19), 11 patients had progressed and 5 had died among the 33 patients with metastatic disease, the median progression-free survival in this group being 14 months. Severe hematologic toxicity was uncommon, grade 3-4 neutropenia and thrombocytopenia occurring in 32% and 4% of patients, respectively. Only 2 episodes of neutropenic sepsis were registered. Packed red blood cell transfusions were required in 7 patients. Vomiting, diarrhoea, mucositis and skin toxicity were severe in 6%, 9%, 10%, and 9% of patients, respectively. Peripheral neuropathy was observed in 47% of patients. CONCLUSIONS: The weekly PET administration is a well tolerated and very effective approach in advanced breast cancer patients. It can produce a 40% clinical complete response rate, with a more than 10% pCR rate in patients with T4 disease, and an about 80% ORR in those with distant metastases. A phase III trial comparing PET with a standard every 3 weeks epirubicin-taxol administration is underway.

Weekly docetaxel plus gemcitabine or vinorelbine in refractory advanced breast cancer patients: a parallel dose-finding study. Southern Italy Cooperative Oncology Group (SICOG).

PURPOSE: The objective of this study was to determine the docetaxel MTD when combined with gemcitabine or vinorelbine in advanced breast cancer patients who had received previous anthracycline-based chemotherapy for advanced disease. PATIENTS AND METHODS: Advanced breast cancer patients aged between 18 and 70 with ECOG PS 0-2 who had not responded to, or had relapsed after, first-line anthracycline-based chemotherapy, were randomized to receive either gemcitabine 1000 mg/m2 or vinorelbine 25 mg/m2 in combination with escalating doses of docetaxel (starting from 30 mg/m2), all on days 1 and 8 every three weeks. Escalation was stopped if > 33% of patients treated at a given dose level showed DLT at the first cycle. RESULTS: A total of 34 patients with locally advanced (8) or metastatic disease (26) were treated, for a total of 94 cycles delivered. Nineteen patients received docetaxel in combination with gemcitabine and 15 with vinorelbine. All patients had been pretreated with anthracyclines, and 24 of 34 had also received weekly dose-dense paclitaxel. A docetaxel dose of 40/m2 proved to be safe when combined on days 1 and 8 with gemcitabine, while a dose of 35 mg/m2 was tolerated in combination with vinorelbine. Overall, nine episodes of DLT, all of them neutropenia, occurred at the first cycle. Considering all 94 cycles, grades 3 or 4 neutropenia and thrombocytopenia occurred in 15 (44%), and 7 (20%) patients. Non-hematologic toxicity was mild, except for three cases of grade 2 peripheral neuropathy. All patients were assessed for response on an 'intent-to-treat' basis. Overall, five partial responses were recorded (docetaxel + gemcitabine = 3 and docetaxel + vinorelbine = 2), for a 15% (95% CI: 5%-31%) overall response rate. Only 1 of 24 (4%) patients who had received weekly dose-dense paclitaxel responded to treatment. CONCLUSIONS: The weekly docetaxel administration in combination with either gemcitabine or vinorelbine is a well-tolerated treatment for heavily pretreated advanced breast cancer patients. This approach, although sometimes capable of achieving a major response, does not seem advisable in advanced breast cancer patients refractory to both anthracyclines and paclitaxel.

Cisplatin-epirubicin-paclitaxel weekly administration in advanced breast cancer: a phase I study of the Southern Italy Cooperative Oncology Group.

PURPOSE: Both cisplatin and epirubicin have been shown to enhance the antitumor activity of paclitaxel in vitro. Weekly administration could result in a substantial improvement in the therapeutic index of cisplatin and paclitaxel. This study was aimed at determining the MTDs of epirubicin and paclitaxel given weekly with a fixed dose of cisplatin. PATIENTS AND METHODS: Sixty-three breast cancer patients with advanced disease (24 locally advanced and 39 metastatic), who had not received prior chemotherapy (except adjuvant), received weekly cisplatin (CDDP) doses of 30 mg/m2 together with escalating doses of paclitaxel (PTX) and epirubicin (EPI) for a minimum of six cycles. The dose escalation was stopped if DLT occurred during the first six treatment cycles in > 33% of patients of a given cohort. RESULTS: Nine different dose levels were tested, for a total of 506 weekly cycles delivered. G-CSF support on days 3-5 of each week was also given in the last four cohorts (24 patients). An overall 11 patients showed DLT in the first six cycles. EPI and PTX doses up to 40 and 85 mg/m2/week, respectively, were safely delivered without G-CSF support. However, the actually delivered mean dose intensity was only 64% in this cohort. Therefore, the dose escalation continued with the addition of filgrastim from day 3 to day 5 each week. Doses of EPI and PTX up to 50 and 120 mg/m2/week were administered without observing DLT in the first six cycles in more than one third of the patients enrolled. No toxic deaths were observed. Only two patients had to be hospitalized because of sepsis. Grade 3-4 neutropenia, thrombocytopenia, and anemia occurred in 25, 9, and 16 patients, respectively. Alopecia was almost universal. Other nonhematologic toxicities were generally mild, being of grade 3-4 in only eight patients (fatigue and loss of appetite in two cases, diarrhoea in four cases, peripheral neuropathy and mucositis in one case). Fifteen complete and 37 partial responses have been registered for an 82% (95% CI = 71-91) overall clinical response rate (ORR). Eight complete and 14 partial responses occurred in the 24 patients with locally advanced disease, for a 92% (95% CI = 73-99) ORR, as compared to seven complete and 23 partial responses in the 39 women with metastatic disease, 77% (95% CI = 61-89). A clear dose-response relationship was not observed, since an overall response rate of at least 70% was achieved at all dose levels. However, the ORR increased to 92% in the last four cohorts which included patients who received higher doses of EPI and PTX with G-CSF support. All of the 24 patients with locally advanced disease underwent modified radical mastectomy with axillary dissection. Three of them showed no invasive cancer on pathologic examination, and in another five patients a tumor smaller than 1 cm was found in the surgical specimen of the breast. At a nine-month median follow-up (range 2-14), 11 patients have progressed and three have died. Twenty-three out of 24 patients who underwent surgery are still free from progression. The one-year projected progression-free survival is 77% for the whole population. CONCLUSIONS: The CDDP/EPI/PTX weekly administration is a well tolerated and very effective approach in advanced breast cancer patients. Full doses of all the three drugs can be delivered even in absence of G-CSF support. A very impressive increment of the dose-intensity can be obtained, however, by adding filgrastim. A phase II study is under way to better define the therapeutic efficacy of this regimen in patients with advanced breast cancer.

Cisplatin-topotecan-paclitaxel weekly administration with G-CSF support for ovarian and small-cell lung cancer patients: a dose-finding study.

PURPOSE: Paclitaxel (PTX) and topotecan (TPT) have shown promising antitumor activity in both ovarian cancer (OC) and small-cell lung cancer (SCLC) patients. This phase I study was aimed at determining the maximum tolerable dose (MTD) of TPT given weekly over 30 min in combination with fixed doses of cisplatin (CDDP) and (PTX), and with G-CSF support. PATIENTS AND METHODS: Forty-four patients with OC (19) or SCLC (25), either chemo-naïve (20) or pretreated (24) received CDDP 40 mg/m2, PTX 85 mg/m2 (one-hour infusion) and escalating TPT doses (starting from 0.75 mg/m2) in a 30-min infusion in weekly administration. Filgrastim 5 mg/kg was administered on days 3 to 5 of each week. RESULTS: Eight different dose levels were tested for a total of 295 delivered cycles. The dose escalation was interrupted at the TPT dose of 2.50 mg/m2. No toxic deaths occurred in this study. Grade 3 to 4 neutropenia, thrombocytopenia, and anemia occurred in 15 patients (36 cycles), seven patients (15 cycles), and four patients (five cycles), respectively. Severe vomiting and diarrhoea occurred in seven and four patients. Peripheral neuropathy was recorded in 11 patients (42 cycles), but it was never severe. An overall 11 of 19 (58%) OC and 11 of 25 (44%) SCLC patients obtained objective responses. Eight patients showed complete responses (three OC and three SCLC). Among the 20 chemo-naïve patients, 9 of 11 (82%) OC and seven of nine (78%) SCLC responded. CONCLUSIONS: The CDDP/TPT/PTX weekly administration with filgrastim support represents a well-tolerated and active therapeutic approach in both chemo-naïve and pretreated OC and SCLC patients. A weekly dose of TPT of 2.25 mg/m2 is recommended for the phase II study.

Technetium-99m-pentavalent dimercaptosuccinic acid uptake in Hurthle cell tumor of the thyroid.

In a patient with metastatic Hurthle cell carcinoma of the thyroid, a subgroup of follicular carcinoma, scintigraphy with pentavalent 99mTc-labeled dimercaptosuccinic acid (V)DMSA showed a significant uptake of the radiopharmaceutical in all tumor sites. We suggest that the accumulation of 99mTc-(V)DMSA within metastases of Hurthle cell thyroid tumor may have a useful role in the staging of these patients, especially when radioiodine fails to concentrate.

High serum thyroglobulin levels. Diagnostic indicators in patients with metastases from unknown primary sites.

Patients with metastases from differentiated thyroid carcinoma have a good chance of long-term survival when the diagnosis is prompt and appropriate therapy is applied early. This is also true for patients with metastases in the bone, taking into account that an appropriate therapy, usually 131-I, may be palliative in some cases. This study investigates whether serum thyroglobulin (Tg) measurement in patients with cold thyroid nodule and metastases from an unknown primary site could help identify a differentiated thyroid carcinoma. The results obtained show that Tg measurements is a useful adjunctive test when used with fine-needle aspiration biopsy. In particular, very high Tg levels point to metastatic thyroid cancer, whereas lower levels do not help determining whether metastatic cancer is of thyroid origin or not.

Pre-and postoperative Tc 99m scanning in monitoring pulmonary perfusion in the tetralogy of Fallot.

Angiocardiopneumographic scanning with Tc 99m was used in pulmonary perfusion and intracardiac shunt before and after radical corrective surgery of the tetralogy of Fallot. The study was carried out on 25 patients with the tetralogy of Fallot undergoing radical treatment with infundibular patch. Preoperative scanning has shown increased thickening of right ventricle and contemporary injection of pulmonary artery and aorta, the latter with a much higher radioactivity; the obstruction to the right flow was not clearly defined with respect to morphology and function, pulmonary perfusion has shown an extremely poor radioactivity and prolonged duration. Scanning following surgical treatment showed normal right and left phase and absence of residual shunts. Captation of marker in the lungs was always complete. Such data illustrate the many advantages gained by the use of non invasive diagnostic procedures in cardiology and "the first pass technique" in the evaluation of results of surgical treatment.
