Cleft palate and ADULT phenotype in a patient with a novel TP63 mutation suggests lumping of EEC/LM/ADULT syndromes into a unique entity: ELA syndrome

Acro-dermato-ungual-lacrimal-tooth (ADULT) syndrome is a rare condition belonging to the group of ectodermal dysplasias caused by TP63 mutations. Its clinical phenotype is similar to ectrodactyly-ectodermal dysplasia-cleft lip/palate (EEC) and limb-mammary syndrome (LMS), and differs from these disorders mainly by the absence of cleft lip and/or palate. We report on a 39-year-old patient who was found to be heterozygous for a c.401G > T (p.Gly134Val) de novo mutation of TP63. This patient had the ADULT phenotype associated with cleft palate. Our findings, rather than extend the clinical spectrum of ADULT syndrome, suggest that cleft palate can no longer be considered an element for differential diagnosis for ADULT, EEC, and LMS. Our data, added to other reports on overlapping phenotypes, support the combining of these three phenotypes into a unique entity that we propose to call "ELA syndrome," which is an acronym of ectrodactyly-ectodermal dysplasia-cleft lip and palate, limb-mammary, and ADULT syndromes.     

Thyroid nodule shape suggests malignancy

OBJECTIVE: To evaluate if a nodule with shape taller than wide (anteroposterior/transverse diameter ratio, A/T > or = 1) is a good predictor of malignancy independent of the size. METHODS: We retrospectively examined the cytological and histological results of 7455 nodules (5198 patients) referred for ultrasound-guided-fine needle aspiration cytology (US-FNAC) in our hospital from January 1991 to September 2004. RESULTS: A suitable FNAC was obtained from 6135 nodules (4495 patients); 34.6% were less than 1 cm in diameter (small nodules, SN). A diagnosis of carcinoma was histologically confirmed in 284/349 suspicious lesions after FNAC. The size of carcinoma nodules was not significantly associated with the occurrence of extracapsular growth (large nodules (LN): 10.5%, SN: 4.9%, NS) and lymph node metastasis (LN: 23.6%, SN: 25.0%, NS). Malignant lesions showed microcalcifications more frequently than benign nodules (72.2 vs 28.7%; P < 0.001; (odds ratio, OR(confidence intervals, CI) = 9.9(7.2-13.4)). Similarly, A/T > or = 1 (76 vs 40%; P < 0.001; OR(CI) = 8.6(5.5-13.1)), blurred margins (52.8 vs 18.8%; P < 0.001; OR(CI) = 7.7(5.6-10.2)), solid hypo-echoic appearance (80.6 vs 52.4%; P < 0.001; OR(CI) = 3.2(2.2-4.3)) and intranodular vascular pattern (type 2) (61.6 vs 49.7%; P < 0.001; OR(CI) = 1.7(1.3-2.3)) were significantly more frequent in malignant than in benign nodules. CONCLUSIONS: Our data show that no single parameter, including nodule size, satisfactorily identifies a subset of patients to be electively investigated by FNAC. We concluded that A/T > or = 1 with at least two of US features (microcalcification, blurred margins, hypo-echoic pattern) is today the best compromise between missing cancers and cost-benefit.     

Use of the Internet by women seeking information about potentially teratogenic agents

Objective

The aim of this study was to evaluate if the Internet provides evidence-based information to women seeking information about teratogenic risk factors and women's risk perception. Furthermore, we evaluated the possible risk related to teratogen exposure in the study sample and analysed age, gravidity, educational level, geographic location, marital status and type of exposure compared to a control group made up of women who did not use the Internet to search for teratogen-related information.

Study design

Between October 2008 and June 2009, a questionnaire was administered to pregnant women calling our Teratology Information Service concerning a suspected teratogenic exposure.

Results

Fifty-seven percent (n = 116) of callers had used the Internet to find medical information about their exposure, while 43% (n = 87) had not. Internet users had a medium-high level of education and consulted the Internet because of its convenience, usually early in their pregnancy. We verified the accuracy of the information the women obtained from the Internet and found that 59.5% (n = 69) of women received evidence-based answers; 18.1% (n = 21) were informed that their exposure was dangerous when it was not; 4.3% (n = 5) were wrongly reassured; and the rest (n = 18) were not able to interpret the data they found or found no relevant information.

Conclusions

Internet use during pregnancy is a widespread phenomenon as the Internet offers the opportunity to share apprehensions and doubts with other women, but it can often lead to increased and unjustified anxiety. Medical information published on websites cannot be considered a substitute for informed medical advice, and patients should not take any action before consulting with a health care professional.     

Reversible Parkinsonian syndrome associated with anti-neuronal antibodies in acute EBV encephalitis: a case report

We report a case of subacute-onset isolated parkinsonian syndrome in a 16 years old patient. Epstein-Barr infection was diagnosed according to serologic evidences. Parkinson-like syndrome completely recovered after 60 days. Autoantibodies reacting against a 130 Kda antigens expressed in human neuroblastoma cell line were detected. Pathogenesis and differential diagnosis are briefly discussed. EBV testing could be worthwhile in juvenile, acute-onset, parkinsonism.
