Local reactions to the second dose of the BNT162 COVID-19 vaccine
Multiple strategies have been implemented worldwide to fight the
burden of the pandemic caused by COVID-19, with vaccination being
one of the most promising.1
Notably, the first vaccine to be authorized in Italy was the
BNT162 mRNA-based vaccine, which has also been approved in
the USA, United Kingdom, and Canada.1,2 As a matter of fact, RNA
vaccines are immunogenic and cost-effective.
Marked pseudoepitheliomatous hyperplasia secondary to a red-pigmented tattoo. a case report
Tattooing is gaining increasing popularity in developed countries in recent years. Adverse cutaneous reactions of many different types against coumponds in tattoo inks are being reported more and more often in medical literature,especially against red-pigmented tattoo. Delayed immune-mediated reactions can manifest in several ways and different histological patterns have been described This article is protected by copyright. All rights reserved
Insolita causa di addome acuto in paziente adulto: l’ileo biliare
L’ileo biliare è una condizione morbosa rara descritta tra le complicanze della litiasi della colecisti. È causa dell’1-3% delle ostruzioni meccaniche del piccolo intestino. Interessa più frequentemente pazienti di età compresa tra 63 e 85 anni. La diagnosi pre-operatoria
è generalmente posta con ritardo variabile da 1 a 10 giorni per l’assenza di una sintomatologia specifica.
Caso clinico. Gli Autori riportano il caso di un uomo di 50 anni in cui è stata posta diagnosi di occlusione meccanica del piccolo intestino da voluminosa concrezione litiasica. L’occlusione ileale è stata dimostrata con la TC. Il paziente è stato sottoposto in urgenza ad intervento
chirurgico, in un unico tempo, di enterolitotomia, colecistectomia e riparazione della fistola duodenale. Il decorso clinico è stato regolare e il paziente è stato dimesso in XIV giornata.
Discussione. Nel nostro caso la diagnosi di ileo biliare è stata posta con un ritardo di 5 giorni. L’ecotomografia del fegato e delle vie biliari non è stata in grado di visualizzare la colecisti. La diagnosi è stata
posta con la TC che si conferma gold standard diagnostico.
Conclusioni. Lo stato clinico del paziente influenza la strategia chirurgica. Nel nostro paziente, considerato a basso rischio, è stato possibile l’intervento chirurgico in un unico tempo. La procedura in due tempi, enterolitotomia e successiva colecistectomia con riparazione della fistola,
va riservata ai pazienti ad alto rischio
Thyroid Cancer Imaging In Vivo by Targeting the Anti-Apoptotic Molecule Galectin-3
Background The prevalence of thyroid nodules increases with age, average 4-7% for the U.S.A. adult population, but it is much higher (19-67%) when sub-clinical nodules are considered. About 90% of these lesions are benign and a reliable approach to their preoperative characterization is necessary. Unfortunately conventional thyroid scintigraphy does not allow the distinction among benign and malignant thyroid proliferations but it provides only functional information (cold or hot nodules). The expression of the anti-apoptotic molecule galectin-3 is restricted to cancer cells and this feature has potential diagnostic and therapeutic implications. We show here the possibility to obtain thyroid cancer imaging in vivo by targeting galectin-3. Methods The galectin-3 based thyroid immuno-scintigraphy uses as radiotracer a specific 99mTc-radiolabeled mAb. A position-sensitive high-resolution mini-gamma camera was used as imaging capture device. Human galectin-3 positive thyroid cancer xenografts (ARO) and galectin-3 knockout tumors were used as targets in different experiments in vivo. 38 mice with tumor mass of about 1 gm were injected in the tail vein with 100 ?Ci of 99mTc-labeled mAb to galectin-3 (30 ?g protein/in 100 ?l saline solution). Tumor images were acquired at 1 hr, 3 hrs, 6 hrs, 9 hrs and 24 hrs post injection by using the mini-gamma camera. Findings Results from different consecutive experiments show an optimal visualization of thyroid cancer xenografts between 6 and 9 hours from injection of the radiotracer. Galectin-3 negative tumors were not detected at all. At 6 hrs post-injection galectin-3 expressing tumors were correctly visualized, while the whole-body activity had essentially cleared. Conclusions These results demonstrate the possibility to distinguish preoperatively benign from malignant thyroid nodules by using a specific galectin-3 radio-immunotargeting. In vivo imaging of thyroid cancer may allow a better selection of patients referred to surgery. The possibility to apply this method for imaging and treatment of other galectin-3 expressing tumors is also discussed

In our clinic, we have observed a group of adult patients who
had COVID-19 who referred to us because of persisting cutaneous
lesions, which had appeared during the disease peak
Klinefelter syndrome: case report
The aim of this work is to describe the problems of child dentistry affected by Klinefelter's syndrome.
Through the presentation of a clinical case that was followed by a Pediatric Dentistry, University Sapienza of Rome.
Interceptive therapy aims to eliminate the functional interference that occurs during growth.
Conclusion. For this reason it’s a must for the dentist to carefully monitor the oral health of the small patient immediately
