Should We Rule out Celiac Disease in Recurrent Headache Disorders? A Review of the Literature.

Recurrent headaches, encompassing migraine and tension-type headaches, represent prevalent conditions affecting individuals across different age groups, exerting a substantial influence on daily functioning and quality of life. Headaches serve as common manifestations of underlying health issues. Among these, celiac disease, an autoimmune disorder activated by gluten consumption, has emerged as a noteworthy concern. Recent research indicates a correlation between celiac disease and heightened susceptibility to headaches, particularly migraines. Celiac disease (CD) is an immune-mediated systemic, widespread disorder presenting a heterogeneous constellation of symptoms with a relatively easy diagnosis and therapy. Among signs and symptoms exhibited in celiac disease patients, headache is one of the most common neurological issues addressed among both adults and children. Headache disorders and CD are highly prevalent in the general population; for this reason, any causal association between these conditions and the role of a gluten-free diet (GFD) has been debated. The aim of this manuscript is to review the current scientific literature regarding the potential association between CD and headaches and the beneficial effects of a GFD. Among the various authors, in our opinion, the current state of the evidence suggests a significant role for the early screening of CD during the initial diagnosis of recurrent headaches, either in adults or children.

Consents or waivers of responsibility? Parents' information in NICU.

BACKGROUND: Informing the patient is a base of modern medicine; nonetheless, a great discrepancy exists between hospitals on the way this information should be administered. This is particularly important when the patient are babies: the information should be given to their parents who should approve or disapprove the treatment. Aim of this study is to assess the adequacy of the information administered to the parents of babies admitted into the Neonatal Intensive Care Units. METHODS: We analyzed the consent forms of center-north Italy NICUs. To this aim, we assessed if the forms had acceptable length and other features; we then asked some volunteers to simulate an information process and to score the forms for their easiness, comprehensibility and explicability to others. RESULTS: Twenty-one NICUs accepted to participate. Only 7 out of 21 had an adequate information form; the other 14 could be described as "waiver of responsibility" (WOR), because they were too prolix and contained too many hypothetical procedures. The overall level of easiness, comprehensibility and explicability to others was suboptimal, being lower in those forms we defined WOR. CONCLUSIONS: The results are far to be optimal. More care should be devoted to the process of informing parents at the admission into the NICU: an information overload should be avoided and information should be tailored on the baby's state. Further analysis should be devoted to whether the use of WOR is routine in other countries.

Management of methylmalonic acidemia (MMA) with N-carbamylglutamate: A case report from Italy.

BACKGROUND: Methylmalonic acidemia (MMA) is an inborn error of metabolism whose optimal management, especially in the long-term remains to be established. METHODS: We describe the case of a child with MMA mut0 who was in a cycle of episodes of decompensation and hospitalization when we started to use carglumic acid (CA), a well-known adjunctive therapy to standard care for the treatment of acute hyperammonemia due to MMA. RESULTS: Using the lowest effective therapeutic dose of CA and adjusting the patient's diet with caloric and protein intake adequate for her age and pathology, we managed to keep ammonium levels within the normal range, and to ensure a normal growth pattern. CONCLUSION: The present case adds further confirmation of the long-term management of MMA using CA, focusing on the long duration of follow up and on the use of a lower dose of CA in real life settings.

Coffin-Siris syndrome and epilepsy.

Coffin-Siris syndrome is a rare genetic disorder defined by the presence of particular facial traits, congenital malformations, intellectual disability, and speech impairment. Epilepsy in Coffin-Siris syndrome has only occasionally been reported, and its features are poorly defined. We provide a detailed description of the clinical and instrumental findings of three patients with Coffin-Siris syndrome and epilepsy. The clinical diagnosis in our patients was confirmed by molecular analysis, which identified the presence of de novo mutations of ARID1B and SMARCB1 genes, in two patients and one patient, respectively. All the patients presented with epilepsy, with a mean age of seizure onset of 5.5 years. Seizures were brief and had a focal onset with secondary generalization. Electroencephalographic recording documented a unilateral, and less commonly bilateral, paroxysmal activity in the temporal, parietal, and occipital regions. Clinical response to anticonvulsive therapy was satisfactory, with a low rate of seizure recurrence. Our case series contributes to delineate the phenotype of Coffin-Siris syndrome. We wish this report could pave the way for further studies that will better define the prevalence and clinical manifestations of epilepsy in this rare syndrome.

Periventricular white matter changes in idiopathic intracranial hypertension.

Objective: To evaluate whether increased cerebrospinal fluid (CSF) pressure causes alteration of periventricular white matter (WM) microstructure in patients with idiopathic intracranial hypertension (IIH). Methods: In a prospective study, patients with refractory chronic headache with and without IIH performed a neuroimaging study including 3T MRI, 3D Phase Contrast MR venography, and diffusion tensor imaging (DTI) of the brain. Whole-brain voxel-wise comparisons of DTI abnormalities of WM were performed using tract-based spatial statistics. A correlation analysis between DTI indices and CSF opening pressure, highest peak, and mean pressure was also performed in patients with IIH. Results: We enrolled 62 consecutive patients with refractory chronic headaches. Thirty-five patients with IIH, and 27 patients without increased intracranial pressure. DTI analysis revealed no fractional anisotropy changes, but decreased mean, axial, and radial diffusivity in body (IIHMD = 0.80 ± 0.04, non-IIHMD = 0.84 ± 0.4, IIHAD = 1.67 ± 0.07, non-IIHAD = 1.74 ± 0.05, IIHRD = 0.38 ± 0.04, non-IIHRD = 0.42 ± 0.05 [mm2/sec × 10-3]) of corpus callosum, and in right superior corona radiata (IIHMD = 0.75 ± 0.04, non-IIHMD = 0.79 ± 0.05, IIHAD = 1.19 ± 0.07, non-IIHAD = 1.28 ± 0.09, IIHRD = 0.59 ± 0.03, non-IIHRD = 0.53 ± 0.03 [mm2/sec × 10-3]) of 35 patients with IIH compared with 27 patients without increased intracranial pressure. DTI indices were negatively correlated with high CSF pressures (P < 0.05). After medical treatment, eight patients showed incremented MD in anterior corona radiata left and right and superior corona radiata right. Conclusions: There is significant DTI alteration in periventricular WM microstructure of patients with IIH suggesting tissue compaction correlated with high CSF pressure. This periventricular WM change may be partially reversible after medical treatment.

Prevalence of "unclassified" HPV genotypes among women with abnormal cytology.

BACKGROUND: High risk human papillomaviruses (HPVs) have been unequivocally recognised as the necessary cause of squamous intraepithelial lesions (SIL) and invasive carcinoma of the cervix. The distribution and the role of unclassified risk HPV genotypes in cervical neoplasia has not been fully elucidated. METHODS: Liquid-based cytological samples were collected from 337 women referred for colposcopy following an abnormal cytological diagnosis. HPV DNA was detected by broad-spectrum PCR and genotypes identified by nucleotide sequencing analysis and reverse line blot (RLB). RESULTS: The overall frequency of HPV infection was 36.5% (35 out of 96) in samples negative for intraepithelial lesions or malignancy (NILM), 80% (181 out of 226) in low grade SIL and 93.3% (14 out of 15) in high grade SIL (P < 0.001). Thirty-five different genotypes were identified among the 230 HPV-positive cases. The Group 1 oncogenic viruses (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59) were found in 21.9, 46.5, and 86.7% of NILM, low grade SIL and high grade SIL, respectively. The Group 2A, including the probably oncogenic virus HPV68, was found in 1 and 0.8% of NILM and low grade SIL, respectively. The Group 2b possibly oncogenic HPVs (HPV34, 53, 66, 67, 70, 73, 82 and 85) were found in 4.2, 21.7 and 26.7% of NILM, low grade SIL and high grade SIL, respectively. The unclassified viruses (HPV12, 42, 54, 55, 61, 62, 81, 83, 84, 89, 90, 91) were detected in 8.3 and 14.6% of NILM and low grade SIL, respectively, and never in high grade SIL. CONCLUSIONS: Group 1 HPVs were mainly prevalent in high grade SIL and low grade SIL while Group 2B were equally distributed among the two groups. The dominant frequency of unclassified HPVs in low grade SIL and NILM and their rarity in high grade SIL suggests their marginal role in cervical neoplasia of the studied population.

Cerebrospinal Fluid Pressure-Related Features in Chronic Headache: A Prospective Study and Potential Diagnostic Implications.

Objective: To identify the pressure-related features of isolated cerebrospinal fluid hypertension (ICH) in order to differentiate headache sufferers with ICH from those with primary headache disorder. Methods: In this prospective study, patients with refractory chronic headaches and suspected of having cerebrospinal fluid-pressure elevation without papilledema or sixth nerve palsy, together with controls, underwent 1-h lumbar cerebrospinal fluid pressure monitoring via a spinal puncture needle. Results: We recruited 148 consecutive headache patients and 16 controls. Lumbar cerebrospinal fluid pressure monitoring showed high pressure and abnormal pressure pulsations in 93 (63 %) patients with headache: 37 of these patients with the most abnormal pressure parameters (opening pressure above 250 mm H2O, mean pressure 301 mm H2O, mean peak pressure 398 mm H2O, and severe abnormal pressure pulsations) had the most severe headaches and associated symptoms (nocturnal headache, postural headache, transient visual obscuration); 56 patients with the less abnormal pressure parameters (opening pressure between 200 and 250 mm H2O, mean pressure 228 mm H2O, mean peak pressure 316 mm H2O, and abnormal pressure pulsations) had less severe headaches and associated symptoms. Conclusions: Nocturnal and postural headache, and abnormal pressure pulsations are the more common pressure-related features of ICH in patients with chronic headache. Abnormal pressure pulsations may be considered a marker of ICH in chronic headache.

BCL10 expression and localization in ocular adnexa MALT lymphomas: a comparative cytogenetic and immunohistochemical study.

T(1;14) (p22;q32) involving BCL10 and IGH genes is a rare but recurrent chromosomal aberration in MALT-type lymphoma. It is rarely described in ocular adnexa B cell lymphomas, although nuclear BCL10 shuttling seems to be critical for disease progression in this district. We have evaluated the translocations MALT lymphoma-related in a series of 45 ocular adnexa cases, focusing in particular on their relation with BCL10 expression and its cellular topographic distribution. A prognostic tissue microarray (TMA) with ocular adnexa MALT lymphomas was designed. A study of BCL10 expression and its topographic distribution was performed through immunohistochemistry. In addition the assessment of t(14;18) (q32;q21), t(1;14) (p22;q32) and t(11;18) (q21;q21) was determined by Fluorescent In Situ Hybridization (FISH). Our series revealed t(14;18) (q32;q21) in 6/43 cases (14,3%). t(1;14) (p22;q32), never described in ocular adnexa MALT lymphomas, was observed in 3/31 (9,7%), two of which exhibited the gain of 3' upstream BCL10 gene signal (4%), whereas no case showed t(11;18) (q21;q21). Moreover, BCL10 expression was observed in 18/45 cases. In particular its nuclear expression was revealed in 12/45 cases, cytoplasmic expression in 5/45 and both cytoplasmic and nuclear expression in 1/45. Statistical analysis demonstrated that while BCL10 cytoplasmic expression is significantly related to the presence of the investigated chromosomal aberrations, in particular with t(14;18) (q32;q21), BCL10 nuclear shuttling does not show any correlation with these translocations. Our data support that BCL10 nuclear distribution is neither related to BCL10 rearrangement nor to other known translocations.

Hyalinizing clear cell carcinoma of the parotid gland: report of a recurrent case with aggressive cytomorphology and behavior diagnosed on fine-needle cytology sample.

A case of recurrent hyalinizing clear cell carcinoma (HCCC) of the parotid gland in a 46-year-old female is here introduced. The patient had undergone a left superficial parotidectomy 6 months ago in another institution for an alleged benign, circumscribed mass 2.4 cm in diameter of the left parotid gland. Histopathological examination revealed a poorly differentiated HCCC bearing a EWSR-1 translocation on FISH examination. Fine Needle Cytology (FNC) was performed on three separate soft tissue masses in the pre-masseterine area and a cytological diagnosis of recurrent, poorly differentiated, possibly aggressive variant of HCCC, was rendered. FISH performed on a destained Diff Quik stained smear demonstrated an ESWR-1 translocation, which supported the cytopathological diagnosis. The cytomorphologic features and the differential diagnosis of this aggressive variant of HCCC are briefly discussed.

MYC chromosomal aberration in differential diagnosis between Burkitt and other aggressive lymphomas.

Myc oncogenetic deregulation is abundantly described in several solid human cancer and lymphomas. Particularly, Burkitt's lymphoma belongs to the family of B Non Hodgkin aggressive lymphomas. Although it is morphologically characterized, immunophenotypic and cytogenetic diagnosis remains complex. In 2008, the WHO has introduced a new diagnostic class of aggressive B-cell lymphomas with features intermediate between BL and DLBCL. This diagnostic class represents a temporary container of aggressive B-cell lymphomas, not completely belonging to the BL and DLBCL categories. The importance of establishing a correct diagnosis would allow a better prognostic classification and a better therapeutic approach. In this review, we summarize the main diagnostic approaches necessary for appropriate diagnoses and we emphasize the importance of cytogenetic analysis of the oncogene Myc in the histopathological diagnosis and the prognostic/predictive stratification. In this contest, Myc represents the more involved gene in the development of these lymphomas. Therefore, we analyze the genetic aberrations causing its over-expression and the concomitant deregulation of molecular pathways related to it. We also propose a FISH approach useful in the diagnosis of these lymphomas.

Breast MALT lymphomas: a clinicopathological and cytogenetic study of 9 cases.

Primary breast mucosa-associated lymphoid tissue (MALT) lymphomas are uncommon and restricted diagnostic criteria should be used to exclude breast involvement by systemic lymphomas. The molecular pathogenesis of primary breast MALT lymphomas is not clear because of the rarity of the disease. Generally the molecular studies of MALT lymphoma in extranodal sites have shown the presence of different chromosomal aberrations, mutually exclusive with substantial differences in their frequency relatively to topographic localization. Few cases of breast MALT lymphomas in the literature have been assessed for MALT lymphoma-associated translocations and BCL10 expression, underlying their rarity in primary breast MALT lymphomas. In our study, we analyzed a series of nine cases of primary breast MALT lymphomas. FISH results showed evidence of MALT1 gene rearrangements in four primary breast lymphomas, in particular three cases with t(11;18)(q21;q21) and one case with t(14;18)(q32;q21). In addition, BCL10 gene rearrangement was not observed. There was no evidence of BCL10 gene translocation in any of the neoplasms assessed. Our data indicate that MALT1 gene rearrangements are not rare in primary breast MALT lymphoma in contrast with results of previous series. Finally, t(11;18) has been observed to be significantly associated with high intensity cytoplasmic BCL10 expression underlying cross-talk between MALT1 and BCL10 pathways in the pathogenesis of MALT lymphomas.

Delineation of HER2 gene status in breast carcinoma by silver in situ hybridization is reproducible among laboratories and pathologists.

An automated enzyme metallographic silver in situ hybridization method (SISH) has been reported to successfully determine human epidermal growth factor receptor 2 (HER2) gene amplification. We evaluated the staining and interpretative reproducibility of the HER2 SISH assay at five laboratories and compared SISH results with other in situ hybridization (ISH) methods. The HER2 gene status of 89 breast carcinomas was analyzed in parallel using manual dual-color fluorescence ISH, manual chromogenic ISH, and bright-field automated SISH. A total of 1098 SISH-stained slides were evaluated. For comparison, all specimens were stained by 4B5 immunohistochemistry for HER2 protein expression. Interpretation was performed by pathologists at five different laboratories using the algorithms provided by the manufacturers and the guidelines of American Society of Clinical Oncology/College of American Pathologists. Staining and interpretative reproducibility were measured through the computation of weighted kappa statistics. Following the optimization of SISH staining, 1077/1098 (98%) of slides were evaluable. Excellent reproducibility and efficacy of HER2 SISH staining, and interobserver interpretation (Kw = 0.91), were observed among five sites. For the 89 invasive breast cancer cases, the overall rate of concordance between consensus 4B5 and consensus SISH, fluorescence ISH, and chromogenic ISH was 96.6% (86/89), 97.8% (87/89), and 96.6% (86/89), respectively. Overall concordance between positive and negative SISH and fluorescence ISH results, as well as between individual and consensus positive and negative SISH results, was excellent (P < 0.001).

Canine mastocytoma: report of 8 cases diagnosed by fine needle cytology and clinicopathologic correlations.

BACKGROUND: Mast cell proliferations are commoner in dogs than in humans; mass forming lesions in the former are apt to fine needle sampling and the obtained cytopathological picture might be informing to enhance recognition of similar proliferations in humans. CASE: Clinical and cytopathologic data were collected from 8 cases of canine mastocytomas diagnosed by fine needle cytology. The cytopathologic presentation was correlated with the individual therapy performed and with the clinical stage. In all cases the cytopathological diagnosis was confirmed by histopathologic examination of the excised mass, by necropsy or by response to therapy. CONCLUSION: There are marked similarities between canine and human mastocytomas, despite possible differences in the clinical course of the disease in both species. Canine mastocytomas may hence be used as an animal model of a human disease and, as such, familiarity with their cytologic presentation may be useful for recognizing mast cell proliferations in humans.

Vinorelbine plus 3-weekly trastuzumab in metastatic breast cancer: a single-centre phase 2 trial.

BACKGROUND: After two studies reporting response rates higher than 70% in HER2-positive metastatic breast cancer with weekly trastuzumab and vinorelbine, we planned a phase 2 study to test activity of the same combination, with trastuzumab given every 3 weeks. METHODS: Patients with HER2-positive metastatic breast cancer (3+ at immunohistochemistry or positive at fluorescence in situ hybridization), PS < or =2, normal left-ventricular ejection fraction (LVEF) and no more than one chemotherapy line for metastatic disease were eligible. Vinorelbine (30 mg/m2) was given on days 1 & 8 every 21 and trastuzumab (8 mg/kg day 1, then 6 mg/kg) every 21 days). A single-stage phase 2 design, with p0 = 0.45, p1 = 0.65, type I and II error = 0.10, was applied; 22 objective responses were required in 39 patients. RESULTS: From Nov 2002 to May 2005, 50 patients were enrolled, with a median age of 54 years (range 31-81). Among 40 patients eligible for response assessment, there were 7 complete and 13 partial responses (overall response rate 50%; 95% exact CI 33.8-66.2); 11 patients had disease stabilization, lasting more than 6 months in 10 cases. Response rate did not vary according to patients and tumor characteristics, type and amount of previous chemotherapy. Within the whole series, median progression-free survival was 9.6 months (95% CI 7.3-12.3), median overall survival 22.7 months (95% CI 19.5-NA). Fifteen patients (30%) developed brain metastases at a median time of 12 months (range 1-25). There was one toxic death due to renal failure in a patient receiving concomitant pamidronate. Twenty-three patients (46%) had grade 3-4 neutropenia, 2 (4%) grade 3 anemia, 4 (8%) febrile neutropenia. Two patients stopped treatment because of grade 2 decline of LVEF and one patient because of grade 2 liver toxicity concomitant with a grade 1 decline of LVEF. One patient stopped trastuzumab after 50 cycles because of grade 1 decline of LVEF. CONCLUSION: Although lower than in initial studies, activity of 3-weekly trastuzumab plus vinorelbine fell within the range of results reported with weekly schedules. Toxicity was prevalently manageable. This combination is safe and active for metastatic breast cancer patients who received adjuvant taxanes with anthracyclines.

Estudo do stress e da qualidade de vida de uma amostra de pacientes oncológicos

Este estudo teve por finalidade verificar o nível de qualidade de vida de pacientes oncológicos, se apresentavam sintomas de stress e estratégias adequadas para com ele lidar. Foram sujeitos vinte e três pacientes portadores de câncer, sendo que nove estavam em processo quimioterápicos e cartoze não estavam sendo submetidos a tratamento médico. Os instrumentos de avaliação utilizados foram: inventários de sintomas de stress e qualidade de vida, auto-avaliação da qualidade de vida, análise de estratégias e entrevistas. Verificou-se que os pacientes apresentavam um quadro sintomático de stress e uma qualidade de vida insatisfatória em relação, principalmente, aos aspêctos profissionais e relacionado à saúde. Quanto as estratégias utilizadas pelos sujeitos, elas se mostraram adaptativas porém insuficientes no controle do stress. Conclui-se que a doença, e principalmente fatores oriundos dela, desencadeiam reações de stress e diminuição no nível de qualidade de vida dos pacientes. No entanto, determinadas atitudes de enfrentamento de problemas e estilos de vida dos pacientes, podem reverter essa situação. Futuras pesquisas foram propostas visando um maior desenvolvimento na área da Psico-Oncologia.

This study had for objective to verifying the oncological patients life’s quality level, if they present stress symptoms and adequate strategies for coping with it. Twenty three patients with cancer were subjects, where nine had finished the chemotherapic process and fourteen were not being submitted to medical treatment. The evaluation instruments used were: stress symptom inventory, life quality inventory, life quality self-evaluation, strategy analysis and interview. It was verified that the patients presented stress symptoms and unsatisfatory quality of life in relation to, mainly, profissional aspects and health relation. As far as the strategies used by the subjects, they seemed to be adaptative however unsufficient in the management of the stress. It was concluded that the disease, and mainly, it’s related consequences arose reactions of stress and a decrease in the patients life quality. However, a resolute attitude of problems coping and life styles of the patients, can revert this situation. Future researches were proposed aiming a greater development in the Psico-Oncological area.

A relaçäo entre stress, padräo tipo A de comportamento e crenças irracionais / The relationships between stress, type A behavior and irrational believes

O presente trabalho avaliou a relaçäo entre stress e duas fontes internas de stress: o padräo Tipo A de comportamento (Friedman & Rosenman, 1974) e crenças irracionais (Ellis, 1973). Cem pacientes que procuraram o treino de controle de stress no CPCS foram analisados em termos do nível de stress que apresentavam, o número e o tipo de crenças irracionais e a presença do padräo do Tipo A de comportamento. Observou-se que 73% dos pacientes foram classificados como Tipo A contra 27% classificados como Tipo B. Pacientes do Tipo A tinham um número maior de crenças irracionais. A crença mais freqüentemente exibida foi a de que "se deve ser absolutamente competente, inteligente e merecedor de todo o respeito". A variável sexo näo fez diferença significativa nas conparaçöes feitas. Verificou-se também que a maioria dos pacientes se encontrava na fase de resistência do stress. Os dados foram interpretados a favor da hipótese de que há uma correlaçäo entre stress, Tipo A de comportamento e crenças irracionais
