Sexuality and fertility desire in a large cohort of individuals with 46, XY differences in sex development

Abstract Objective: To analyze aspects of sexual life and fertility desire among 46, XY DSD people, including those who changed their gender. Methods: It is a cross-sectional study including 127 adults (> 16 years of age) with 46, XY DSD (83 females; 44 males) from a Single Brazilian Tertiary-Care Medical Center. Results: Sexual fantasies and masturbation were more frequent in 46, XY DSD males, whereas orgasm and sexual life satisfaction were similar in both genders. More 46, XY DSD men than women had a long-term romantic relationship. 46, XY DSD women with prenatal androgen exposure reported more fear of being romantically rejected. External genitalia appearance at birth did not impact the sexuality of 46, XY DSD women after surgical genital treatment had been completed. Overall, the sexual life was similar between 46, XY men assigned as males and those who changed to the male gender. Regarding sexual orientation, most self-reported as heterosexual (91% and 92% of women and men, respectively). The desire for fertility had a similar prevalence in both genders, but more women than men considered infertility a barrier to a long-term romantic relationship. Twelve individuals (7 males) had children; 10 out of 12 have adopted children. Conclusion: Fertility desire was shared among 46, XY DSD people, regardless of gender. Prenatal androgen exposure reduced the desire for motherhood in 46, XY women. 46, XY DSD people who changed from female to male gender presented similar sexual parameters as those assigned as males. Among females, virilized genitalia at birth did not affect sexuality once the surgical treatment is completed.

Fructosamine and glycated hemoglobin as biomarkers of glycemic control in people with type 2 diabetes mellitus and cancer (GlicoOnco study)

Abstract Introduction Glycemic control is important to avoid diabetes complications in individuals with cancer. There is no evidence for HbA1c and fructosamine as reliable biomarkers in these conditions. There are particularities in caring for patients with diabetes and cancer that can alter these biomarkers. Objective The aim of this study was to evaluate HbA1c and fructosamine as glycemic biomarkers in people with type 2 diabetes and cancer, undergoing clinical or surgical oncological treatment. Methods The authors conducted a single-center, retrospective analysis with people who have cancer and diabetes. Comparison of glycemic biomarkers (HbA1c, fructosamine, and Self-Monitoring of Blood Glucose [SMBG]) was performed including evaluation in individuals undergoing chemotherapy, using glucocorticoids, with anemia, hypoproteinemia or with reduced estimated Glomerular Filtration Rate (eGFR). Results There was a strong positive correlation between fructosamine and HbA1c (n = 318, r= 0.66, p < 0.001) in people with diabetes and cancer even in those under chemotherapy (n = 101, r= 0.61, p < 0.001) or using glucocorticoids (n = 96, r= 0.67, p<0.001). There was a strong correlation between HbA1c and fructosamine in subjects with anemia (n = 111, r= 0.66, p < 0.001), hypoproteinemia (n = 54, r= 0.67, p < 0.001), or with eGFR ≥ 60 mL/min/1.73 m2 (n = 189, r= 0.70, p < 0.001), and moderate correlation with hypoalbuminemia (n = 21, r= 0.54, p = 0.001) and with reduced eGFR (n = 67, r= 0.57, p < 0.001). The correlations between fructosamine and HbA1c with SMBG were moderate (n = 164, r= 0.49, p < 0.001; n = 111, r= 0.55, p < 0.001, respectively), strong in subjects undergoing chemotherapy, with hypoalbuminemia or hypoproteinemia, and at least moderate, if eGFR < 60 mL/min/1.73 m2 or with anemia. Conclusions Fructosamine and HbA1c can be used as glycemic biomarkers in people with diabetes and cancer, even in those with anemia, hypoproteinemia, or undergoing chemotherapy.

Central adrenal insufficiency: who, when, and how? From the evidence to the controversies - an exploratory review

ABSTRACT Central adrenal insufficiency (CAI) is a life-threatening disorder. This occurs when ACTH production is insufficient, leading to low cortisol levels. Since corticosteroids are crucial to many metabolic responses under organic stress and inflammatory conditions, CAI recognition and prompt treatment are vital. However, the diagnosis of CAI is challenging. This is not only because its clinical presentation is usually oligosymptomatic, but also because the CAI laboratory investigation presents many pitfalls. Thus, the clarification of when to use each test could be helpful in many contexts. The CAI challenge is also involved in treatment: Several formulations of synthetic steroids exist, followed by the lack of a biomarker for glucocorticoid replacement. This review aims to access all available literature to synthesize important topics about who should investigate CAI, when it should be suspected, and how CAI must be treated.

Androgen insensitivity syndrome: a review

ABSTRACT Androgenic insensitivity syndrome is the most common cause of disorders of sexual differentiation in 46,XY individuals. It results from alterations in the androgen receptor gene, leading to a frame of hormonal resistance, which may present clinically under 3 phenotypes: complete (CAIS), partial (PAIS) or mild (MAIS). The androgen receptor gene has 8 exons and 3 domains, and allelic variants in this gene occur in all domains and exons, regardless of phenotype, providing a poor genotype - phenotype correlation in this syndrome. Typically, laboratory diagnosis is made through elevated levels of LH and testosterone, with little or no virilization. Treatment depends on the phenotype and social sex of the individual. Open issues in the management of androgen insensitivity syndromes includes decisions on sex assignment, timing of gonadectomy, fertility, physcological outcomes and genetic counseling.

Thickened pituitary stalk associated with a mass in the sphenoidal sinus: an alarm to suspect hypophysitis by immunoglobulin g4?

Introduction Hypophysitis is a chronic inflammation of the pituitary gland of complex and still incompletely defined pathogenesis. It belongs to the group of non-hormonesecreting sellar masses, sharing with them comparable clinical presentation and radiographic appearance. Objectives Describe the case of immunoglobulin G4 (IgG4)-related hypophysitis presenting as a mass in the sphenoid sinus. Resumed Report A 40-year-old Brazilian man had a diagnosis of central diabetes insipidus since 2001 associated with pituitary insufficiency. Pituitary magnetic resonance imaging revealed a centered pituitary stalk with focal nodular thickening and the presence of heterogeneous materials inside the sphenoid sinus. The patient was treated with testosterone replacement therapy. Laboratory results revealed increased IgG4 serum. Conclusion IgG4-related hypophysitis should be considered in patients with pituitary insufficiency associated with sellar mass and/or thickened pituitary stalk. IgG4 serum measurement for early diagnosis of IgG4-related hypophysitis should be performed.

Alterações neuroendócrinas em pacientes com traumatismo cranioencefálico / Neuroendocrine disorders in traumatic brain injury patients

O traumatismo cranioencefálico (TCE) corresponde a uma das principais causas de morte em adultos jovens. Alguns pacientes com TCE podem ser vítimas de várias alterações hormonais decorrentes do trauma. Algumas são facilmente reconhecíveis, como diabetes insipidus, enquanto outras podem passar despercebidas inicialmente, como a deficiência do hormônio do crescimento (GH). As alterações neuroendócrinas após a ocorrência de trauma podem cursar com deficiências da hipófise anterior, da posterior ou de ambas, acometer apenas um eixo hormonal ou vários e, ainda, ser transitórias ou permanentes. A grande maioria dos pacientes que apresentam disfunção neuroendócrina foi vítima de traumas considerados moderados ou graves pela escala de Glasgow. No entanto, a maioria dos estudos não evidenciou relação entre a gravidade da lesão e a ocorrência de alteração hipofisária pósTCE. As deficiências hipofisárias devem ser tratadas precocemente, uma vez que déficits hormonais hipofisários dificultam a recuperação dos pacientes traumatizados, constituindo-se em fator de pior prognóstico. Apesar da frequência com que ocorrem os TCE, existem poucos estudos a respeito das complicações neuroendócrinas decorrentes...

Traumatic brain injury (TBI) is one of the main causes of death in young adults. Some cases of TBI could lead to the development of easily recognizable diabetes insipidus. In other cases it can lead to alterations in the endocrine axis that are more difficult to notice at the beginning and that can occur together with other hormone deficiencies. The majority of patients with neuroendrocrine dysfunction were TBI victims with a Glasgow Coma Scale scores of 3-13 (moderate and severe trauma). However, previous studies did not show correlationships between the severity of injury and pan-hypopituitarism after TBI. The pituitary disorders have to be treated as soon as possible because it makes the recovery of TBI patients more difficult and lead to a worse prognosis. Despite the number of studies about TBI, actually there are only a few studies concerning the secondary neuroendocrine complications...

Possibilidade de associação de melanoma e acromegalia / Possibility of an association between melanoma and acromegaly

Neoplasias como câncer de próstata, mama e cólon estão relacionadas à acromegalia. Raras vezes foi mencionada a associação com melanoma. Descreve-se caso de paciente com acromegalia no qual foi identificada lesão melanocítica suspeita, com posterior confirmação de melanoma. A excisão cirúrgica da lesão levou à cura da neoplasia. Chama-se a atenção para a necessidade de exame cuidadoso da pele de pacientes com acromegalia.

Neoplasias such as prostate, breast, and colon cancer are commonly associated with acromegaly. However, the association of the latter with melanoma has been rarely mentioned. We describe the case of a patient with acromegaly in whom a suspicious melanocytic lesion was detected, and later confirmed to be melanoma by means of biopsy. Surgical excision of the lesion led to the cure of the neoplasia. More attention should be drawn to the need for careful skin examination of patients with acromegaly.

Neuropatia autônoma cardiovascular em pacientes com diabetes “mellitus” tipo 2 / Cardiovascular autonomic neuropathy in diabetic mellitus type 2 patients

A neuropatia autônoma acomete grande parte dos pacientes diabéticos. Este acometimento pode envolver diversos órgãos e sistemas e isso geralmente ocorre de forma desigual. O envolvimento do sistema nervoso autônomo no decurso do diabetes mellitus (DM) é bem estabelecido e está associado com aumento da mortalidade. A presença de neuropatia autônoma cardíaca (NAC), evidenciada por alterações nas variações de freqüência cardíaca, está associada a uma mortalidade de 29 por cento em 10 anos, enquanto que naqueles pacientes ilesos de NAC essa taxa representa apenas 6 por cento. Devido ao valor prognóstico na NAC, é importante avaliarmos a sua presença nos pacientes com DM, bem como orient´-alos quanto às suas associações. Descrevemos os dados encontrados em nosso ambulatório e discutimos as evidências na NAC encontradas na literatura
