Abstract
Macrodontia is a dental anomaly pertaining to the increased size of a tooth or multiple teeth. Double teeth are dental abnormalities concerning tooth morphology and the term traditionally refers to geminated or fused teeth. These anomalies may manifest in both primary and permanent dentitions and usually become apparent in childhood. They may cause a variety of clinical sequelae, including orthodontic complications, such as crowding, ectopic eruption of adjacent teeth and periodontal concerns. Double teeth are also at a higher risk of developing caries. The aesthetic implications of these dental anomalies can affect the psychosocial development of a patient. This, together with the range of functional repercussions, can often need dental treatment to improve quality of life. The functional and aesthetic complexities that may arise in the affected patients can require endodontic, restorative, surgical and/or orthodontic input as part of the management strategy and execution. We present four clinical cases of paediatric patients where a range of management approaches were employed for both macrodontia and double teeth.

Abstract
OBJECTIVES Pituitary gigantism is a rare condition and it often has an identifiable genetic cause. In this article we report a case of a young girl with pituitary gigantism and two genetic changes. CASE PRESENTATION A 15-year-old girl with primary amenorrhea was diagnosed with a growth hormone (GH) and prolactin (PRL)-producing tumor, needing surgery and medical treatment with octreotide in order to achieve disease control. The co-occurrence of an AIP mutation and a MEN1 variant of uncertain significance was demonstrated in this patient. The germline mutation involving AIP was inherited from her father who at the age of 55 was unaffected and the MEN1 variant was a de novo duplication of the region 11q13.1. The latter variant, not previously reported, is unlikely to be pathogenic. Nonetheless, screening for other components of multiple endocrine neoplasia type 1 (MEN1) was performed and proved negative. CONCLUSIONS The rare co-occurrence of an AIP mutation and a MEN 1 variant of uncertain significance was demonstrated in this patient.

Abstract
Macrodontia is a dental condition where a tooth or group of teeth are abnormally larger than average. Functional and aesthetic discrepancies may arise in affected individuals resulting in lowering the quality of life. It has been noted that macrodontia is associated with several genetic and endocrine abnormalities. Among which, KBG syndrome is a rare genetic disorder characterized by developmental and dental abnormalities. This case report provides a brief overview of the significance of macrodontia, along with presenting a case of KBG syndrome with atypical features in a South African, 16-year-old female. The dental manifestations are often overshadowed by other more conspicuous and complex syndromic features. Recognition of both the clinical and oral changes that occur in KBG syndrome facilitates accurate diagnosis and appropriate management of this condition. The authors highlight the importance for clinicians to be cognizant of the clinical implications of macrodontia.

Abstract
PURPOSE Non-syndromic pituitary gigantism (PG) is a very rare disease. Aryl hydrocarbon receptor-interacting protein (AIP) and G protein-coupled receptor 101 (GPR101) genetic abnormalities represent important etiologic causes of PG and may account for up to 40% of these cases. Here, we aimed to characterize the clinical and molecular findings and long-term outcomes in 18 patients (15 males, three females) with PG followed at a single tertiary center in Sao Paulo, Brazil. METHODS Genetic testing for AIP and GPR101 were performed by DNA sequencing, droplet digital PCR and array comparative genomic hybridization (aCGH). RESULTS Pathogenic variants in the AIP gene were detected in 25% of patients, including a novel variant in splicing regulatory sequences which was present in a sporadic male case. X-LAG due to GPR101 microduplication was diagnosed in two female patients (12.5%). Of interest, these patients had symptoms onset by age 5 and 9 years old and diagnosis at 5 and 15 years, respectively. X-LAG, but not AIP, patients had a significantly lower age of symptoms onset and diagnosis and a higher height Z-score when compared to non-X-LAG. No other differences in clinical features and/or treatment outcomes were observed among PG based on their genetic background. CONCLUSION We characterize the clinical and molecular findings and long-term outcome of the largest single-center PG cohort described so far.

Abstract
INTRODUCTION Gigantism is a rare pediatric disease characterized by increased production of growth hormone (GH) before epiphyseal closure, that manifests clinically as tall stature, musculoskeletal abnormalities, and multiple comorbidities. MATERIALS AND METHODS Case series of 6 male patients with gigantism evaluated at the Endocrinology Service of Hospital de San José (Bogotá, Colombia) between 2010 and 2016. RESULTS All patients had macroadenomas and their mean final height was 2.01 m. The mean age at diagnosis was 16 years, and the most common symptoms were headache (66%) and hyperhidrosis (66%). All patients had acral changes, and one had visual impairment secondary to compression of the optic chiasm. All patients underwent surgery, and 5 (83%) required additional therapy for biochemical control, including radiotherapy (n = 4, 66%), somatostatin analogues (n = 5, 83%), cabergoline (n = 3, 50%), and pegvisomant (n = 2, 33%). Three patients (50%) achieved complete biochemical control, while 2 patients showed IGF-1 normalization with pegvisomant. Two patients were genetically related and presented a mutation in the aryl hydrocarbon receptor-interacting protein (AIP) gene (pathogenic variant, c.504G>A in exon 4, p.Trp168*), fulfilling the diagnostic criteria of familial isolated pituitary adenoma. CONCLUSIONS This is the largest case series of patients with gigantism described to date in Colombia. Transsphenoidal surgery was the first-choice procedure, but additional pharmacological therapy was usually required. Mutations in the AIP gene should be considered in familial cases of GH-producing adenomas.

Abstract
In the general population, height is determined by a complex interplay between genetic and environmental factors. Pituitary gigantism is a rare but very important subgroup of patients with excessive height, as it has an identifiable and clinically treatable cause. The disease is caused by chronic growth hormone and insulin-like growth factor 1 secretion from a pituitary somatotrope adenoma that forms before the closure of the epiphyses. If not controlled effectively, this hormonal hypersecretion could lead to extremely elevated final adult height. The past 10 years have seen marked advances in the understanding of pituitary gigantism, including the identification of genetic causes in ~50% of cases, such as mutations in the AIP gene or chromosome Xq26.3 duplications in X-linked acrogigantism syndrome. Pituitary gigantism has a male preponderance, and patients usually have large pituitary adenomas. The large tumour size, together with the young age of patients and frequent resistance to medical therapy, makes the management of pituitary gigantism complex. Early diagnosis and rapid referral for effective therapy appear to improve outcomes in patients with pituitary gigantism; therefore, a high level of clinical suspicion and efficient use of diagnostic resources is key to controlling overgrowth and preventing patients from reaching very elevated final adult heights.

Abstract
There have been very few cases of pituitary calcified associated with McCune Albright syndrome. Pituitary calcification is quite rare by itself. Unlike this is a benign disease, its behavior is very aggressive and this highlights the need of a multidisciplinary team. It is mandatory to rule out a whole work up when McCune Albright syndrome is suspected to stratify risks and survival.
Background McCune-Albright’s syndrome (MAS) is a rare disorder that is characterized by café-au-lait macules, fibrous dysplasia of the skull and endocrinopathies like excessive secretion of growth hormone by a hyper-functional pituitary adenoma (PA). Case We describe the case of a 43-year-old male with history of Gigantism in 1990 secondary to a GH-secreting pituitary macroadenoma that was treated via microscopic transsphenoidal surgery at that time. He was reported as asymptomatic for 26 years until he developed headache and right temporal hemianopia with left amaurosis. Also ptosis and proptosis was found caused by a re-growth of the tumor on the follow up MRI. A second surgical procedure was performed via a dorsolateral craniotomy. Gross total resection was also achieved with a Neuropathology report of a pituitary adenoma tissue accompanied by extended dystrophic calcification and bone formation. Conclusion This is a rare case of MAS. Gigantism within the context of a pituitary calcification raises special diagnostic and therapeutic challenges. The cause of the excessive secretion of GH in MAS is not well understood concluding that it seems to be a different etiology of patients with Acromegaly and Gigantism in non-MAS patients.

Abstract
BACKGROUND Acromegaly is a rare and underdiagnosed disorder caused, in more than 95% of cases, by a growth hormone (GH)-secreting pituitary adenoma. The GH hypersecretion leads to overproduction of insulin-like growth factor 1 (IGF-1) which results in a multisystem disease characterized by somatic overgrowth, multiple comorbidities, physical disfigurement, and increased mortality. OBJECTIVE This article aims to review the clinical features of acromegaly at diagnosis. DISCUSSION/CONCLUSION Acromegaly affects both males and females equally and the average age at diagnosis ranges from 40 to 50 years (up to 5% of cases < the age 20). Due to insidious onset and slow progression, acromegaly is often diagnosed five to more than ten years after its onset. The typical coarsening of facial features include furrowing of fronthead, pronounced brow protrusion, enlargement of the nose and the ears, thickening of the lips, skin wrinkles and nasolabial folds, as well as mandibular prognathism that leads to dental malocclusion and increased interdental spacing. Excessive growth of hands and feet (predominantly due to soft tissue swelling) is present in the vast majority of acromegalic patients. Gigantism accounts for up to 5% of cases and occurs when the excess of GH becomes manifest in the young, before the epiphyseal fusion. The disease also has rheumatologic, cardiovascular, respiratory, neoplastic, neurological, and metabolic manifestations which negatively impact its prognosis and patients quality of life. Less than 15% of acromegalic patients actively seek medical attention for change in appearance or enlargement of the extremities. The presentation of acromegaly is more often related to its systemic comorbidities or to local tumor effects.

Abstract
Acromegaly is a rare condition necessitating large population studies for the generation of reliable epidemiological data. In this review, we systematically analysed the epidemiological profile of this condition based on recently published population studies from various geographical areas. The total prevalence ranges between 2.8 and 13.7 cases per 100,000 people and the annual incidence rates range between 0.2 and 1.1 cases/100,000 people. The median age at diagnosis is in the fifth decade of life with a median diagnostic delay of 4.5-5 years. Acral enlargement and coarse facial features are the most commonly described clinical manifestations. At the time of detection, most of the tumors are macroadenomas possibly relating to diagnostic delays and posing challenges in the surgical management. Increased awareness of acromegaly amongst the medical community is of major importance aiming to reduce the adverse sequelae of late diagnosis and treatment, improve patient outcomes and, hopefully, reduce the burden on the health care system.

Abstract
PURPOSE Acromegaly in infancy is extremely rare. We describe a 32 year old woman who presented at 6 months of age with isolated macrocephaly, followed by accelerated linear growth. At 21 months of age, her head circumference was 55 cm (+5.5 SD), height was 97.6 cm (+4.4 SD) and weight was 20.6 kg (+6.2 SD). She had markedly elevated levels of growth hormone (GH) (135 ng/ml), IGF-1 (1540 ng/ml) and prolactin (370 ng/ml). A pituitary macroadenoma was surgically resected. Immunohistochemical staining was positive for GH. Post-operatively, she developed ACTH and TSH deficiency and diabetes insipidus. METHODS Long term clinical follow-up and genetic testing with chromosomal microarray analysis. RESULTS Despite GH deficiency, she grew well until 7 ½ years old, with subsequent decline in growth velocity, and received GH therapy for 5 years. Puberty was initiated with estrogen therapy. As an adult, she has no stigmata of acromegaly, with a height of 164.5 cm and non-acromegalic features. IGF-1 has remained in the low normal range. Prolactin has been mildly elevated. Serial MRIs have shown no evidence of tumor recurrence. She receives replacement therapy with hydrocortisone, levothyroxine and DDAVP. Chromosomal microarray analysis revealed that she has X-linked acrogigantism (X-LAG) due to a de novo duplication of Xq26.3 (516 kb). She recently became pregnant following ovarian stimulation and chorionic villus sampling revealed that she is carrying a male with the same duplication. CONCLUSION This report provides detailed long term clinical follow-up of a patient with X-LAG syndrome.

Abstract
Familial pituitary adenomas account for approximately 5–8% of all pituitary adenomas. Besides the adenomas occurring as part of syndromic entities that group several endocrine or nonendocrine disorders (multiple endocrine neoplasia type 1 or 4, Carney complex and McCune–Albright syndrome), 2–3% of familial pituitary adenomas fit into the familial isolated pituitary adenomas (FIPA) syndrome, an autosomal dominant condition with incomplete penetrance. About 20% of FIPA cases are due to mutations in the AIP gene and have distinct clinical characteristics. Recent findings have isolated a new non-AIP FIPA syndrome called X-linked acrogigantism, resulting from a microduplication that always includes the GPR101 gene. These new advances in the field of pituitary disease are opening up a new challenging domain to both clinicians and researchers. This review will focus on these recent findings and their contribution to the diagnosis and the management of familial pituitary adenomas.
