AIM: Arrhythmogenic right ventrticular dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterized by fibrofatty replacement and a high risk of ventricular arrhythmias (VA) and sudden cardiac death (SCD). The aim of the present investigation is to examine the pathological profile and the clinical correlations in a group of ARVD/C patients. METHODS: We conducted a multicenter study evaluating 47 patients (31 men; mean age 37±14 years) with definite ARVD/C. Diagnosis was established according to the actual clinicomorphologic criteria at autopsy or clinically. We divided the study population in 2 different groups. First group included 28 alive patients and the second 19 patients dead suddenly. RESULTS: Age at presentation was different in the two groups (P=0.0015). We observed an important association regarding the risk of sudden death and the history of physical exercise (P=0.0017). Moreover patients with negative outcome (i.e., SCD, cardiac transplantation, congestive heart failure) had a significantly association with biventricular form of ARVD/C (P=0.0034) and age presentation (P=0.003). Left ventricular (LV) involvement was frequently observed in the two groups (17% and 32% respectively). Post-mortem examination revealed frequent inflammatory infiltrates (26%) indicating active myocarditis, which probably justify the fatal arrhythmic events occurred in these patients. CONCLUSION: Frequent LV involvement justifies the recent adoption of the broad term Arrhythmogenic Cardiomyopathy. Early age presentation, sport activity and the biventricular form of ARVD/C represent important predictors of adverse outcome that can be useful to early identify patients at high risk.

Pulmonary thromboembolism is a common cause of in-hospital death. In moderate or high risk patients undergoing laparotomy, acute and long-term mortality can be effec-tively reduced with an appropriate prophylactic drug treatment, while in low-risk patients undergoing laparoscopy, the correlation between the thromboembolism risk and the pro-cedure itself, as well as potential benefits of thromboprophylaxis are, at present, unclear. Here we report the case of E., a 49-year-old woman with patent foramen ovale, consid-ered to be at low risk of thromboembolism, who experienced a sudden cardiopulmonary arrest following a laparoscopic cholecystectomy and died four days later. . The purpose of this case report is to highlight the necessity of continuing large sample studies on the correlation between laparoscopic surgery and thromboembolism in low-risk patients.

Kawasaki disease (KD) was first described in 1967 by Kawasaki, who defined it as ?mucocutaneous lymph node syndrome?. KD is an acute systemic vasculitis, which mainly involves medium calibre arteries; its origin is unknown, and it is observed in children under the age of 5, especially in their third year. The principal presentations of KD include fever, bilateral nonexudative conjunctivitis, erythema of the lips and oral mucosa, changes in the extremities, rash, and cervical lymphadenopathy. Within KD, oral mucositis ? represented by diffuse mucous membrane erythema, lip and tongue reddening and lingual papillae hypertrophy with subsequent development of strawberry tongue ? can occur both in the acute stage of the disease (0-9 days), and in the convalescence stage (>25 days) as a consequence of the pharmacological treatment. KD vascular lesions are defined as systemic vasculitis instead of systemic arteritis. This study analyzed the anatomical-pathological substrata of oral mucositis in a baby affected by Kawasaki disease and suddenly deceased for cardiac tamponade caused by coronary aneurysm rupture (sudden cardiac death of a mechanical type).

BACKGROUND: Lichen planus (LP) is a mucocutaneous inflammatory dermatosis that frequently involves the oral and genital mucosae. Patients with LP affecting these sites are often seen by oral medicine specialists or gynaecologists who work in isolation and depend heavily on histopathologists to help them in confirming the diagnosis. There are few studies in the literature combining the experiences of these specialists who share the care of patients with both oral and genital LP. OBJECTIVES: To estimate the prevalence of vulval LP (VLP) in a cohort of patients with histologically confirmed oral LP (OLP). METHODS: The study group consisted of 42 women histologically diagnosed with OLP. The mean age was 60.5 years (range 27-81). They underwent genital examination, colposcopy and vulvoscopy. For the histological confirmation of clinical VLP biopsies were performed whenever a clinical lesion was found. Oral and genital biopsy specimens were processed through histological and immunohistochemical staining. Histological diagnoses of LP were made according to the modified World Health Organization histopathological criteria proposed by van der Meij and van der Waal for the diagnosis of OLP, and extended to VLP. Patients with clinical evidence, but without the histological confirmation of OLP and VLP, were excluded from the study group. RESULTS: Thirty-two vulval and one vaginal biopsy specimens were obtained. Histological diagnoses were confirmed in 24 of 32 (75%) patients who underwent a vulval biopsy: these represent 57% (24 of 42) of the study group. Of the 12 patients free of symptoms such as itching, burning and dyspareunia, but with clinical vulval lesions, 11 (92%) had histological confirmation of VLP. Vulval lichen sclerosus was ascertained in five of 32 (16%) cases. CONCLUSIONS: This study showed a 57% prevalence of VLP in selected patients with OLP. The high prevalence of VLP of 92% in the women who were free of vulval symptoms confirmed the usefulness of this careful integrated approach.

Glycogenosis type II or Pompe disease is an inherited autosomal recessive disorder known in 3 different clinical forms (infantile, juvenile and adult). We report on a case diagnosed as a classic infantile form with the worst outcome of all 3 described, if we had followed and executed a correct and complete diagnostic pathway. A 7 months old female child was admitted for fever and dyspnoea. At chest auscultation weepings and weezings were found; on the cardiac apex a murmur due to mitralic failure was retrieved. The thorax X-ray showed a greatly increased heart shadow with a cardiothoracic index of 0.75. ECG showed high voltages and signs of bilateral ventricular hypertrophy. Cardiac ultrasonography confirmed the presence of a big heart with an enormous swollen left ventricle and a severe mitralic failure. The clinical diagnosis of infantile Pompe disease was confirmed by the almost total absence of cellular acid a-glucosidase activity but we couldn't perform the assay because of the rapid exitus of our patient, which occurred before glycogen storage disease II was suspected. So, we tried to compare our case with others reported in the literature in order to ratify our diagnostic hypothesis. The contribution of genetic counseling practiced on all the couples at risk remains useful every time that a certain diagnosis is made.

Intrauterine infections may be due to a variety of pathogens other than the TORCH groups ones. Although Candida Albicans is frequently isolated within the urogenital tract of pregnant women, the fetal infection is rarely reported. We now report on a 26 weeks preterm baby in whom a Candida infection was diagnosed at birth in relation to gravidic anamnesis and typical micotic manifestations upon the placenta and the umbilical cord. Intensive cares and pharmacological treatment induced a progressive improvement of the clinical course and normalization of the laboratory parameters.

OBJECTIVES: Sjögren's syndrome is a chronic inflammatory disease. The detection of chronic inflammatory infiltrates containing >50 lymphocytes (lymphocytic focus) per 4 mm2 tissue in minor salivary gland biopsies is a diagnostic parameter of the disease. The aim of the study was to examine if an increase in the tissue area of a single minor labial salivary gland biopsy through serial histological sections in patients affected by primary Sjögren's syndrome could facilitate the detection of the diagnostic focus score (grades >1 or >2). METHODS: We observed 24 labial salivary gland biopsies from patients affected by primary Sjögren's syndrome, diagnosed according to the clinical-laboratory criteria proposed by the American-European Consensus Group. The analysis was carried out on sections (n= 72) obtained at three different levels at 200 micrometers from one another. The serial sections regarding the 3 levels were reviewed by the same oral pathologist, who detected both the total number of foci, and their surface, calculating a cumulative focus score. RESULTS: No significant correlation was found between the number of lobules per histological section and the focus score (Pearson correlation 0.363, p= 0.01). No significant variation in focus score distribution was identified in the three serial histological levels at 200 micrometers from one another. From the comparison between the number of lobules observed and the focus score grade, no direct proportionality between the amount of parenchyma analyzed and the focus score was found. CONCLUSIONS: The focus score remained unchanged in the serial sections at different depths.
