RESUMO

BACKGROUND: Well-developed collaterals are assumed as a marker of viability and ischemia in chronic total occlusions (CTO). We aim to correlate viability and ischemia with collateral presence and extent in CTO patients by cardiac magnetic resonance (CMR). METHODS: Multicentre study of 150 CTO patients undergoing stress-CMR, including adenosine if normal systolic function, high-dose-dobutamine for patients with akinetic/>2 hypokinetic segments and EF ≥35%, otherwise low-dose-dobutamine (LDD); all patients underwent late gadolinium enhancement (LGE) imaging. Viability was defined as mean LGE transmurality ≤50% for adenosine, as functional improvement for dobutamine-stress-test, ischemia as ≥1.5 segments with perfusion defects outside the scar zone. RESULTS: Rentrop 3/CC 2 defined well-developed (WD, n = 74) vs poorly-developed collaterals (PD, n = 76). Viability was equally prevalent in WD vs PD: normo-functional myocardium with ≤50% LGE in 52% vs 58% segments, p = 0.76, functional improvement by LDD in 48% vs 52%, p = 0.12. Segments with none, 1-25%,26-50%,51-75% LGE showed viability by LDD in 90%,84%,81%,61% of cases, whilst in 12% if 76-100% LGE (p < 0.01). There was no difference in WD vs PD for ischemia presence (74% vs 75%, p = 0.99) and extent (2.7 vs 2.8 segments, p = 0.77). CONCLUSIONS: In a large cohort of CTO patients, presence and extent of collaterals did not predict viability and ischemia by stress-CMR. Scar extent up to 75% LGE was still associated with viability, whereas ischemia was undetectable in 25% of patients, suggesting that the assessment of CTO patients with CMR would lead to a more comprehensive evaluation of viability and ischemia to guide revascularization.

RESUMO

BACKGROUND: Classic Hodgkin lymphoma (cHL) is a lymphoid malignancy in which the microenvironment, where the neoplastic cells are immersed, contributes to the lymphomagenesis process. Epstein-Barr virus (EBV) presence also influences cHL microenvironment composition and contributes to pathogenesis. An increase in PDL1 expression in tumor cells and at the microenvironment was demonstrated in adult cHL. Therefore, our aim was to assess PD1/PDL1 pathway and EBV influence on this pathway in pediatric cHL, given that in Argentina, our group proved a higher incidence of EBV-associated pediatric lymphoma in children. METHODS: For that purpose, EBV presence was assessed by in situ hybridization, whereas PD1 and PDL1 expressions were studied by immunohistochemistry. PDL1 genetic alterations were analyzed by FISH, and survival was evaluated for PD1 and PDL1 expressions. RESULTS: EBV presence demonstrated no influence neither on PD1 expression at the microenvironment nor on PDL1 expression at HRS tumor cells. Unexpectedly, only 38% pediatric cHL displayed PDL1 genetic alterations by FISH, and no difference was observed regarding EBV presence. However, in EBV-related cHL cases, a higher number of PDL1 + cells were detected at the microenvironment. CONCLUSION: Even though a high cytotoxic environment was previously described in EBV-related pediatric cHL, it might be counterbalanced by an immunoregulatory micro-environmental PDL1 + niche. This regulation may render a cytotoxic milieu that unsuccessfully try to eliminate EBV + Hodgkin Reed Sternberg tumor cells in pediatric patients.

RESUMO

PURPOSE: The state of limited resource settings that Coronavirus (COVID-19) pandemic has created globally should be taken seriously into account especially in healthcare sector. In oncofertility, patients should receive their fertility preservation treatments urgently even in limited resource settings before initiation of anticancer therapy. Therefore, it is very crucial to learn more about oncofertility practice in limited resource settings such as in developing countries that suffer often from shortage of healthcare services provided to young patients with cancer. METHODS: As an extrapolation during the global crisis of COVID-19 pandemic, we surveyed oncofertility centers from 14 developing countries (Egypt, Tunisia, Brazil, Peru, Panama, Mexico, Colombia, Guatemala, Argentina, Chile, Nigeria, South Africa, Saudi Arabia, and India). Survey questionnaire included questions on the availability and degree of utilization of fertility preservation options in case of childhood cancer, breast cancer, and blood cancer. RESULTS: All surveyed centers responded to all questions. Responses and their calculated oncofertility scores showed different domestic standards for oncofertility practice in case of childhood cancer, breast cancer, and blood cancer in the developing countries under limited resource settings. CONCLUSIONS: Medical practice in limited resource settings has become a critical topic especially after the global crisis of COVID-19 pandemic. Understanding the resources necessary to provide oncofertility treatments is important until the current COVID-19 pandemic resolves. Lessons learned will be valuable to future potential worldwide disruptions due to infectious diseases or other global crises.

RESUMO

INTRODUCTION: The management of patients with advanced gastric cancer requires a stable venous access required at different stages of disease (treatment phase, palliative phase). Totally implantable central venous access in the arm, named PICC-PORT, is used in a patient with results of extensive skin burns of the neck, chest and right arm and surgical outcomes of multiple skin grafts of chest. The described clinical case is the first event in the scientific literature. PRESENTATION OF CASE: We report a case of a patient with results of extensive skin burns of the neck, chest and right arm and surgical outcomes of multiple skin grafts of chest that must perform chemotherapy with a port. In this patient, due to the difficulty of implanting a door in the cervico-thoracic district, we opt for the totally subcutaneous implantation of the vascular device (PICC-PORT 5 Fr) in the left arm. DISCUSSION: In this patient for the difficulty of implanting a port in the cervico-thoracic district, we opt for the totally subcutaneous implantation of the vascular device (PICC-PORT) in the arm. The PICC-PORT is positioned with the same technique as the PICC (ultrasound-guided vein puncture, with modified Seldinger technique and tip location with ECG technique); presents all the functional and aesthetic advantages of a totally subcutaneous device.The case described is the first case in the scientific literature. CONCLUSION: In Europe in recent years for the availability of the vascular device of small dimensions and materials increasingly compatible, the "PICC-PORT" is positioned in the veins of the arm with ultrasound-guidance without complications such as pneumothorax, arterial puncture, hematoma of the neck, Pinch-off syndrome, such as the clinical case presented with extensive scars on the chest and neck. Thoracic devices (chest port, tunnel venous catheter) are not indicated in thickened and inelastic skins, due to the high risk of dehiscence of the surgical wound.

RESUMO

The microenvironment in classical Hodgkin lymphoma (cHL) comprises a mixture of different types of cells, which are responsible for lymphoma pathogenesis and progression. Even though microenvironment composition in adult cHL has been largely studied, only few groups studied pediatric cHL, in which both Epstein Barr virus (EBV) infection and age may display a role in their pathogenesis. Furthermore, our group described that EBV is significantly associated with cHL in Argentina in patients under the age of 10 years old. For that reason, our aim was to describe the microenvironment composition in 46 pediatric cHL patients. M1-like polarization status prevailed in the whole series independently of EBV association. On the other hand, in children older than 10 years, a tolerogenic environment illustrated by higher FOXP3 expression was proved, accompanied by a macrophage polarization status towards M2. In contrast, in children younger than 10 years, M1-like was prevalent, along with an increase in cytotoxic GrB+ cells. This study supports the notion that pediatric cHL exhibits a particular tumor microenvironment composition.

RESUMO

BACKGROUND: Distal biceps tendon rupture occurs more often in middle-aged male population, involving the dominant arm. In this retrospective study, it's been described the occurrence of the most frequent adverse events and the clinical outcomes of patients undergoing surgical repair of distal biceps tendon rupture with the modified Morrey's double-incision approach, to determine better indications for patients with acute tendon injury. METHODS: Sixty-three patients with acute distal biceps tendon rupture treated with a modified double-incision technique between 2003 and 2015 were retrospectively evaluated at a mean 24 months of follow-up. Clinical evaluation including range of motion (ROM) and isometric strength recovery compared to the healthy contralateral side assessment, together with documentation of nerve injury, was performed. Patients were asked to answer DASH, OES and MEPS scores. RESULTS: The ROM recovery showed excellent results compared to the healthy contralateral side. The reported major complications included: one case of proximal radio-ulnar synostosis, 3 cases of posterior interosseous nerve (PIN) palsy and one case of a-traumatic tendon re-rupture. Concerning minor complications, intermittent pain, ROM deficiency < 30° in flexion/extension and pronation/supination, isometric flexion strength deficiency < 30% and isometric supination strength deficiency < 60%, lateral antebrachial cutaneous nerve (LACBN) injury, were observed. The average DASH score was 8.5; the average OES was 41.5 and the MEPS was 96.3. CONCLUSION: The Morrey modified double-incision technique finds its indication in young and active patients if performed within 2 weeks from injury. If performed by experienced surgeons, the advantages can exceed the drawbacks of possible complications.

RESUMO

BACKGROUND: It is debated whether percutaneous revascularization (PCI) of total coronary chronic occlusion (CTO) is superior to optimal medical therapy (OMT) in improving symptoms, left ventricular (LV) function and major adverse cardiac/cerebrovascular events (MACCE). Furthermore, CTO-PCI is a challenging technique, with lower success rate than in other settings. A systematic analysis of baseline LV function, infarction extent and ischaemic burden to predict response to revascularization has never been performed. PURPOSES: To establish a CMR protocol to identify patients (pts) who can benefit most from CTO-PCI. Myocardial viability/ischaemia retains high biological plausibility as predictors of response to revascularization. Therefore, baseline viability (necrotic tissue extent, response to inotropic stimulation) and ischaemia (perfusion defect, wall motion abnormality during stress) will be studied as potential predictors of mechanical LV segmental improvement and ischaemic burden reduction in CTO territory (primary endpoint), LV remodelling and global function, Seattle Angina Questionnaire, and MACCE improvement (secondary endpoints) in the follow-up. METHODS: Pts with CTO suitable for PCI undergo stress-CMR for viability/ischaemia assessment. Pts with normal LV function undergo adenosine, those with moderately-reduced ejection fraction (EF) and wall motion abnormalities high-dose dobutamine, pts with EF <35% low-dose dobutamine. All pts undergo late gadolinium enhancement and repeat the same scan at 12 ±â€¯3 months, regardless of PCI success or decision for OMT. CONCLUSIONS: A multi-parameter CMR protocol tailored on pts characteristics to study viability/ischaemia could help in identifying responders in terms of LV function, ischaemic burden and clinical outcome among pts suitable for CTO-PCI, improving selection of best candidates to percutaneous revascularization.

RESUMO

Actinic cheilitis (AC) can precede the development of squamous cell carcinoma (SCC) of the lip, a location with higher risk of invasiveness and metastasis. Herein, we reported the use of ingenol mebutate (IngMeb) 0.015% gel on three consecutive days to treat three patients suffering from AC. All the three patients achieved complete clearance of AC with rapid clinical effect, favorable safety profile, good patient's compliance related to short time of applications, and few local skin reactions. So IngMeb is an attractive new therapy for AC. Moreover, the present case report adds further evidence to the usefulness of dermoscopy and Reflectance confocal microscopy (RCM) in the assessment and monitoring of treatment outcome.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: Deprescribing is the process of discontinuing or reducing the dosage of medications that are no longer appropriate or aligned with goals of care, which is paramount in elderly patients with multiple comorbidities and polypharmacy. The objective of this study was to assess the perceptions of primary care physicians on deprescribing for elderly patients and potential barriers to deprescribing that physicians experience in the Local Health Authority (LHA) of Parma, Emilia-Romagna, Italy. METHODS: One hundred and sixty physicians (57% of the total number of primary care physicians in Parma) attended an educational session related to deprescribing and were asked to anonymously complete a paper survey. Participants were asked to assess their level of agreement on nine questions about their perception of deprescribing and potential factors affecting the deprescribing process using a seven-point Likert-type scale. A correlation coefficient was calculated to assess the association between physicians' confidence in deprescribing and attitudes or barriers associated with deprescribing. RESULTS AND DISCUSSION: Many physicians (72%) reported general confidence in their ability to deprescribe. Most respondents (78%) reported they were comfortable deprescribing preventive medications, yet only half (53%) were comfortable deprescribing guideline-recommended therapies. Lack of evidence on discontinuing preventive medicines and concern about withdrawal side effects were reported to impede deprescribing by more than one-third of physicians. When medications were initially prescribed by another physician, 40% of physicians reported hesitance in deprescribing them. About half of physicians (45%) did not feel comfortable deprescribing when patients/caregivers believed that continuation of the medication was needed. Lack of time and difficulty engaging patients/caregivers in the deprescribing process were cited as barriers by about one in four physicians. There was no strong correlation between physicians' confidence and attitudes or barriers associated with deprescribing. WHAT IS NEW AND CONCLUSION: The study results show that physicians believe they are generally comfortable with deprescribing, although there are still several factors that hamper their ability to engage in the process. An improved understanding of physicians' views on deprescribing may help guide further research, and policies to help patients remain healthy while streamlining their medication regimen.

RESUMO

BACKGROUND: Ingenol mebutate (IngMeb) 0.015% gel is an approved field treatment option for non-hyperkeratotic non-hypertrophic actinic keratosis (AK) of face and scalp. Efficacy of IngMeb has been assessed only on a clinical ground, in the majority of studies. Dermoscopy is a pivotal tool for the diagnosis of AK, while its role in evaluating the response to non-surgical therapies for AK has not been fully defined. OBJECTIVES: Our study aims to determine whether some dermoscopic features of AK of the face and scalp areas may independently predict the response to IngMeb therapy. METHODS: Clinical and dermoscopic responses, 1 month after 0.015% IngMeb therapy, were retrospectively evaluated using a per-patient and per-lesion approach. Safety was evaluated through local skin reaction composite score calculation. Demographic, clinical and dermoscopic factors were then evaluated via univariate and multivariate logistic regression analysis to assess independent predictors of response. RESULTS: Fifty-five patients with 245 AKs were enrolled. Clinically, per-patient response evaluation identified 25 (45.4%) poor/partial and 30 (54.5%) complete responders, corresponding on a per-lesion approach to 66 (26.9%) and 179 (73.1%) AKs, respectively. Dermoscopy reclassified 14 patients in the per-patient and 48 AKs in the per-lesion analysis from complete to poor/partial responders. Multivariate logistic regression analysis showed that AKs dermoscopically characterized by red pseudonetwork and located on the face were independently associated with a complete dermoscopic response to 0.015% IngMeb therapy, while microerosions were negative predictors. CONCLUSION: Specific dermoscopic features of AK may predict the response to 0.015% IngMeb therapy, together with the location on the face.

RESUMO

BACKGROUND: The aim of our work is to evaluate and critically analyze long-term clinical and radiological data of a new unilateral external fixator (MIKAI KIT FEP©-Mikai S.p.A, Genoa, Italy), in the treatment of humeral shaft fractures. MATERIALS AND METHODS: We reviewed 47 patients affected by humeral fractures that underwent surgery from July 2010 to March 2016 with unilateral external fixator. Demographic characteristics of the patients were recorded, which included age, sex and baseline comorbidities and mechanism of injury. Surgical data such as time of surgery and time of fixation according to AO-type of fracture, clinical objective and subjective outcomes were collected. RESULTS: The mean follow-up was 50.4 months (range 12-74). The patients' average age was 41.8 years (range 14-92). Mean surgical time was 66.8 (±37.7 min); and mean time of fixation was 4.5 (±1.7 months). We observed five delayed union (10.6%); one refracture (2.1%); and one case of non-union (2.1%) who underwent a revision surgery with nailing. No malunion was detected. Average quick-DASH was 11.7 (±14.8). The mean Constant Score at final follow-up was 81.5 (±14). 95.8% of patients were satisfied of our treatment. According to SF-12 scores, we observed 44 (93.6%) good results and 3 (6.4%) poor results. CONCLUSION: We suggest the use of MIKAI KIT FEP© as a feasible option in the treatment of humeral shaft fractures. We reported optimal clinical and radiological outcomes at long-term follow-up. We advocate more powerful evidence to validate this new possible approach.

RESUMO

BACKGROUND: Differences in incidence and survival in osteosarcoma reports are considerable worldwide. PURPOSE: This study describes the incidence and survival of patients with osteosarcoma in Argentina with data from the National Pediatric Cancer Registry (ROHA), and the impact of age, gender, stage, regional, and socioeconomic indicators on outcome. METHODS: Pediatric patients with osteosarcoma reported to ROHA from 2000 through 2013 were analyzed, the annual age-standardized incidence rate (ASR) was calculated using the National Vital Statistics, and survival was estimated. The extended human development index (EHDI) for each reporting region was used as an indicator of socioeconomic status. RESULTS: There were 515 cases of osteosarcoma identified, yielding an ASR of 3.2/1,000,000 children (0-14 years old). The ASR did not vary significantly by year of diagnosis but ranged from 4.0/1,000,000 in the Cuyo/Western Central region to 2.7/1,000,000 in the northeast region (P < 0.000). The estimated 5-year survival rate was 45% (95% confidence interval [CI] 44-51%), with no difference by sex, diagnosis year, region, or EHDI score (P > 0.1 in all cases). Survival rate for localized disease was 52% (95% CI 45-57%) and for metastatic 22% (95% CI 15-30%). CONCLUSIONS: In Argentina, ASR of osteosarcoma is similar to that in high-income countries, but survival is lower in all regions. Future work will focus on identification and reduction of causes of preventable treatment failure.

RESUMO

BACKGROUND: Digital dermoscopy monitoring (DDM) is an effective strategy for melanoma detection. Two methods are currently employed. Short-term follow-up (STFU) for the evaluation of single, atypical lesions to detect subtle changes over a short period of time (3-6 months). Long-term follow-up (LTFU) is recommended for patients with multiple nevi. Although a study demonstrated that STFU improves the patients' compliance for DDM, little remains known about the impact and reliability of STFU in this setting. OBJECTIVES: The aim of this retrospective, observational study was to evaluate the impact and reliability of a schedule combining STFU and LTFU in patients with multiple atypical nevi. METHODS: We searched our database for all cases of patients with multiple atypical nevi occurring between 2006 and 2014. RESULTS: A total of 3823 lesions in 541 patients were dermoscopically monitored (mean number = 7 lesions per patient; median = 6 lesions; range, 2-51). In all, 264 (6.9%) lesions in 184 (34.4%) patients were excised (mean of 0.5 lesions per patient). In total, 197 (74.6%) lesions were excised at follow-up, with melanomas representing 30.5% of lesions excised after follow-up. A total of 30 (33.3%) melanomas were excised at baseline, 23 (25.6%) after STFU and 37 (41.1%) after LTFU. There was no difference in the number of in situ melanomas detected at baseline with those detected after follow-up. The mean Breslow thickness of melanomas detected at baseline was higher than those detected after STFU (P = 0.038) and LTFU (P = 0.055). CONCLUSIONS: Our study confirm that digital dermoscopy follow-up is a valid management strategy for patients with multiple atypical nevi, with short-term monitoring playing an effective role also in this setting of patients.

RESUMO

BACKGROUND: Heterozygous missense mutations in the WT1 gene that affect the function of the wild-type allele have been identified in Denys-Drash syndrome, which is characterized by severe gonadal dysgenesis, early-onset nephropathy and a predisposition to renal and gonadal cancer. Intron 9 splice-site mutations that influence the balance between WT1 isoforms cause a nearly similar phenotype, known as Frasier syndrome. Nonsense mutations and deletions only lead to WT1 haploinsufficiency and, hence, to less severe gonadal dysgenesis and late-onset nephropathy. WT1 analysis is mandatory in 46,XY gonadal dysgenesis with renal abnormality. PATIENT: We describe a newborn with 46,XY severe partial gonadal dysgenesis, in whom structural renal anomalies and proteinuria were excluded. Gonadectomy was performed at the age of 1 month and the microscopy was thought to be suggestive for a gonadoblastoma. At the age of 9 months, the patient presented with a bilateral Wilms tumor. RESULTS: We found a heterozygous WT1 whole-gene deletion but no other gene defects. CONCLUSIONS: This case description illustrates that a WT1 deletion might be associated with a more severe phenotype than previously thought. It also illustrates that, even in the absence of renal abnormality, it is recommended to test promptly for WT1 defects in 46,XY gonadal dysgenesis.

RESUMO

BACKGROUND: Non-functioning (NF) pancreatic neuroendocrine tumors (pNET) often have an indolent outcome. A consensus to submit patients with large (>2 cm) NF-pNET to surgery already exists; but a conservative approach for small (≤2 cm) NF neoplasms has been proposed. AIM: To identify prognostic factors for survival and progression free survival (PFS) of NF-pNET, evaluating whether surgery may be avoided for small NF-pNET. SUBJECTS AND METHODS: Retrospective study of 77 consecutive patients with pNET submitted to surgery, of which 60 were NF. Pathological tissues were revised according to the 2000 and 2010 WHO classifications. Risk factors for survival and PFS were evaluated using the Kaplan-Meier method and the Cox regression model. RESULTS: The 8-year cause-specific survival of NF-pNET was 79.3%. At univariate analysis, high grading, high staging, large tumors, angioinvasion and peri-pancreatic infiltration were significantly associated with a shorter survival; at multivariate analysis only peri-pancreatic infiltration was significantly associated with a shorter NF-pNET survival. Most small NF-pNET were grade 1 (74%), compared to large NF-pNET (27%). Distant metastases were present in 29.7% (n = 11) and 17.4% (n = 4) of patients with large or small NF-pNET, respectively; among the 19 small NF-pNET without metastasis, five had a local malignancy (lymph node metastasis or local infiltration); thus, 39% of the 23 NF-pNET, turned out to have a malignant potential. CONCLUSIONS: Among NF-pNET, large neoplasms were associated with worse outcomes; however, small NF-pNET do not seem to have an invariable benign behavior. Whether surgery should be avoided in all patients with small NF-pNET is questionable.

RESUMO

Dopamine agonists are considered as the first line therapy in prolactin (PRL) secreting pituitary adenomas inducing a normalization of serum PRL and reduction of tumor size. It is known that serum PRL levels, obtained during treatment, are a predictor of tumor shrinkage. Whether PRL suppression below the lower limit of the normal range is related to a greater chance of tumor shrinkage than just its normalization has not been established. This retrospective cohort study was carried out in a tertiary center. Clinical records of 151 patients with PRL-secreting pituitary adenomas (73 micro-, 78 macroadenomas) treated with cabergoline for at least 24 months were analyzed. The adenoma size was analyzed by MRI before and after 24 months of treatment. PRL levels were evaluated every 6 months, assigning a score at each time point (PRL 0 = suppressed; 1 = normal; 2 = above normal). The total score, after 24 months of treatment, was expressed as the sum of the score at each time point and ranged between 0 and 8. A tumor shrinkage was observed in 102/151 patients (67.5%) and it was significantly associated to a lower PRL total score (p = 0.021, OR = 0.85, CI = 0.73-0.97), being significantly more frequent in patients with suppressed PRL than in those with normal PRL (p = 0.045, OR = 0.42, CI = 0.18-0.98) at 24 months. Cabergoline therapy with the goal of achieving PRL levels below the lower limit of normal range can increase the chance to obtain tumor shrinkage of PRL-secreting pituitary adenomas.

RESUMO

AIM: Basal cell carcinoma (BCC) is the most common skin malignant neoplasm in humans. Its localization and its clinical-pathological aspects are fundamental for the treatment and the outcome of these tumors. We wanted to verify if different clinical-pathological subtypes of BCC may be present with different frequencies on single skin areas. METHODS: Three hundred six patients affected by BCC seen in Sant'Andrea Hospital, U.O.C. Dermatology, NESMOS Department, Faculty of Medicine, University of Rome "Sapienza", from January 2008 to December 2010, were retrospectively included in this study. Findings from all patients were tabulated and analyzed to characterize the clinical-pathological aspects of BCC according to their anatomic localization. We considered the following clinical subtypes of BCC, nodular, superficial, sclerodermiform, pearly and ulcerative. RESULTS: One hundred ninety-seven out of 306 patients (64.4%) were localized on the head, 6 (1.9%) on the neck, 73 patients (23.9%) on the trunk, 2 (0.6%) on the perineum, 4 (1.3%) on upper limbs and 24 (7.9%) on legs. On the head BCC were mostly nodular (44.7%). On the trunk they were mostly superficial (34.3%). BCC on legs were ulcerative in all the 24 patients. CONCLUSION: Our data confirm that BCC may have different clinical-pathological aspects on single skin areas. Interestingly in our casistic BCC on the legs were present in an uncommon high percentage. They presented as ulcerative lesions and this fact leads to conclude that in every patient presenting a chronic ulcer on the leg with difficulty to be cured a biopsy is mandatory to put in evidence the possible presence of BCC and consequently to perform the correct surgical treatment to obtain a complete response for the patient.

RESUMO

PURPOSE: Acromegaly usually occurs as a sporadic disease, but it may be a part of familial pituitary tumor syndromes in rare cases. Germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene have been associated with a predisposition to familial isolated pituitary adenoma. The aim of the present study was to evaluate the AIP gene in a patient with gigantism and in her relatives. METHODS: Direct sequencing of AIP gene was performed in fourteen members of the family, spanning among three generations. RESULTS: The index case was an 18-year-old woman with gigantism due to an invasive GH-secreting pituitary adenoma and a concomitant tall-cell variant of papillary thyroid carcinoma. A novel germline mutation in the AIP gene (c.685C>T, p.Q229X) was identified in the proband and in two members of her family, who did not present clinical features of acromegaly or other pituitary disorders. Eleven subjects had no mutation in the AIP gene. Two members of the family with clinical features of acromegaly refused either the genetic or the biochemical evaluation. The Q229X mutation was predicted to generate a truncated AIP protein, lacking the last two tetratricopeptide repeat domains and the final C-terminal α-7 helix. CONCLUSIONS: We identified a new AIP germline mutation predicted to produce a truncated AIP protein, lacking its biological properties due to the disruption of the C-terminus binding sites for both the chaperones and the client proteins of AIP.
