Abstract
Sheehan's syndrome (SS) is a rare but well-characterized cause of hypopituitarism. Data on skeletal health is limited and on microarchitecture is lacking in SS patients. PURPOSE We aimed to explore skeletal health in SS with bone mineral density (BMD), turnover, and microarchitecture. METHODS Thirty-five patients with SS on stable replacement therapy for respective hormone deficiencies and 35 age- and BMI-matched controls were recruited. Hormonal profile and bone turnover markers (BTMs) were measured using electrochemiluminescence assay. Areal BMD and trabecular bone score were evaluated using DXA. Bone microarchitecture was assessed using a second-generation high-resolution peripheral quantitative computed tomography. RESULTS The mean age of the patients was 45.5 ± 9.3 years with a lag of 8.3 ± 7.2 years prior to diagnosis. Patients were on glucocorticoid (94%), levothyroxine (94%), and estrogen-progestin replacement (58%). None had received prior growth hormone (GH) replacement. BTMs (P1NP and CTX) were not significantly different between patients and controls. Osteoporosis (26% vs. 16%, p = 0.01) and osteopenia (52% vs. 39%, p = 0.007) at the lumbar spine and femoral neck (osteoporosis, 23% vs. 10%, p = 0.001; osteopenia, 58% vs. 29%, p = 0.001) were present in greater proportion in SS patients than matched controls. Bone microarchitecture analysis revealed significantly lower cortical volumetric BMD (vBMD) (p = 0.02) at the tibia, with relative preservation of the other parameters. CONCLUSION Low areal BMD (aBMD) is highly prevalent in SS as compared to age- and BMI-matched controls. However, there were no significant differences in bone microarchitectural measurements, except for tibial cortical vBMD, which was lower in adequately treated SS patients.

Abstract
Abstract
Objective. The study was aimed to assess the effect of hydrocortisone (HC) replacement therapy on bone mineral density (BMD) and bone turnover markers in patients with primary adrenal insufficiency (PAI).
Methods. A cross-sectional study was conducted in 37 PAI patients treated with HC. BMD and selected bone turnover markers (β-crosslaps and osteocalcin) were measured. A stepwise binary logistic regression model was applied to determine the independent variables associated with low BMD.
Results. Osteoporosis was noted in 14.3% and osteopenia in 34.3% of cases. These patients were older (p=0.01) and received higher daily HC dose compared to patients with normal BMD (p=0.01). BMD values in the lumbar spine and the femoral neck were negatively correlated with daily HC dose (r=–0.36, p=0.03 and r=–0.34, p=0.05, respectively). Plasma osteocalcin was negatively correlated with disease duration (r=–0.38, p=0.02) and cumulative HC dose (r=–0.43, p<0.01). In multivariate analysis, a daily HC dose ≥12 mg/m2/day was independently associated with a higher risk of osteopenia/osteoporosis [OR (95% CI), 9.0 (1.1–74.6); p=0.04].
Conclusions. Impaired bone mineralization in patients with PAI is correlated with HC dose. A daily HC dose ≥12 mg/m2/day was associated with an increased risk of osteopenia and osteoporosis in these patients.

Abstract
BACKGROUND Sheehan's syndrome (SS) occurs due to ischemic pituitary necrosis resulting from severe postpartum hemorrhage (PPH). SS is characterized by varying degrees of pituitary insufficiency involving mostly the anterior lobe. Comprehensive data on SS apart from endocrine dysfunction is scarcely available. MATERIALS AND METHODS Thirty-eight subjects previously diagnosed with SS were enrolled in this observational study. Their clinical, biochemical, hormonal, radiological data at presentation were recorded from past records and bone density was measured in all. RESULTS Mean (±SD) age was 39 (±8.7) years and diagnostic delay was 9.3 (±5.5) years. All had history of PPH and lactation failure. About 47% were referred from emergency, and rest 53% were diagnosed from outpatient's department. Mean free T4, TSH, prolactin, morning cortisol, FSH, LH, and IGF-1 were mostly low. Panhypopituitarism was present in 97%. Hyponatremia was most common electrolyte imbalance found in about 53%. More than 40% had elevated transaminases. Dyslipidemia especially low HDL was found in 31 (81.5%) subjects. MRI of hypothalamus-pituitary region showed empty sella in 53% and partial empty sella in 47%. About 13% subjects had diabetes mellitus. Low bone mass (BMD Z-Score ≤-1) was seen in 80% and it was more severe (BMD Z-Score ≤-2) in 44% subjects, affecting predominantly lumbar spine. Bone loss at femoral neck was less prominent. CONCLUSION Apart from variable spectrum of clinical presentation, subjects with SS have significant abnormalities in serum electrolytes, metabolic parameters. Low bone mass is also a frequent accompaniment.

Evaluation of bone texture imaging parameters on panoramic radiographs of patients with Sheehan's syndrome: a STROBE-compliant case-control study. Osteoporos Int 2019; 30:2257-2269.

Abstract
UNLABELLED Sheehan's syndrome (SHS) is a rare condition related to the risk of osteoporosis and evaluation of bone texture imaging features on panoramic radiographs would be suitable for this condition, which was the aim of the present study. Fractal dimension, lacunarity, and trabecular morphologic aspects were significantly altered in these patients. INTRODUCTION SHS is an important public health problem particularly in developing countries. It is characterized as postpartum hypopituitarism secondary to obstetric complications-related ischemic pituitary necrosis that shows significant systemic metabolic repercussions. Thus, this study aimed to evaluate bone texture parameters in digital panoramic radiographs of patients with SHS. METHODS A case-control study was conducted with 30 SHS patients from an Endocrinology and Diabetology Service of reference in Brazil, and 30 age- and sex-matched healthy controls. A custom computer program measured fractal dimension, lacunarity, and some morphologic features in the following mandibular regions of interest (50 × 50 pixels): below the mental foramen (F1), between the first and second molars (M1), and at the center of the mandibular ramus (R1). RESULTS The fractal analysis showed a statistically significant difference between the studied groups in all regions of interest. The fractal dimension in F1 (p = 0.016), M1 (p = 0.043), and R1 (p = 0.028) was significantly lower in SHS group, as well as lacunarity in R1 (p = 0.008). Additionally, several morphologic features were statistically significant in the SHS group (p < 0.05). CONCLUSION Therefore, individuals with SHS showed altered imaging texture parameters on panoramic radiographs, which reflect a smaller spatial organization of the bone trabeculae and, possibly, a state of reduced mineral bone density.

Abstract
Sheehan's syndrome (SS) is an important cause of pan-hypopituitarism in women. There is scanty information on bone mineral density (BMD) in this condition. We determined BMD and the changes in BMD after oestrogen (E2) replacement and nutritional supplementation in women with SS. In a cross-sectional study, BMD was measured by DEXA in 83 patients [age (mean ± SD) 42 ± 9.2 years] and compared with an equal number of matched controls. In a sub-set of 19 patients, we conducted an open-label, prospective study to determine changes in BMD after 1 year of replacement of E2, and calcium and vitamin D3 supplementation. All patients had low serum IGF-1 and E2, while 98% had ≥ 3 pituitary hormone deficiencies. Compared with Indian reference standards, 47% had decreased bone mass (Z-score ≤ - 2.0). BMD Z-scores were decreased at all sites, being most marked in the lumbar spine and femoral neck. At the lumbar spine, BMD was lowest among the age group 21-30 years. Women with SS also had significantly lower BMD Z-scores at all three sites on comparison with ethnic controls. On multivariate analysis, BMD Z-score was associated with weight, daily calcium intake and age (lumbar spine). In the prospective study, 1 year of therapy improved BMD Z-score at lumbar spine (- 1.4 ± 1.2 vs. - 1.1 ± 1.1, p = 0.02), but not at hip or femoral neck. In conclusion, patients with SS had significantly lower BMD compared to controls at all three sites. Replacement of E2 and supplementation with calcium/vitamin D3 lead to significant improvement in lumbar spine BMD.

Abstract
Background Sheehan’s syndrome (SS) is one of the leading causes of hypopituitarism in developing countries. It occurs after postpartum necrosis of the pituitary gland, and it is considered a significant public health problem. This paper, apparently unpublished, aimed to perform an analysis on oral aspects in patients with SS. Material and Methods A cross-sectional study was performed with 23 women diagnosed with SS at the Division of Endocrinology and Diabetes (Walter Cantídio University Hospital, Fortaleza, Brazil). Results Data on sociodemographic, dental and salivary flow aspects were collected through a clinical approach and a panoramic radiograph request. The mean age was 64 ± 11.5 years old, with the sample consisting mainly of married women (56.5%), socioeconomic class C2 or D / E (78.2%) and years of education up to 8 years (69.5%). The presence of horizontal bone loss (p<0.001) and bilateral pneumatization of the maxillary sinus (p=0.015) were significant data. The mean number of absent teeth considering all subjects was 23.17±9.7, being statistically significant (p<0.001). In relation to age, the mean number of missing teeth was higher in individuals over 65 years old (p=0.048). Reduced salivary flow was observed in 78.3% of the patients. In a bivariate analysis, considering the outcome variables “missing teeth” and “reduced salivary flow”, it was observed that economic class (p<
0.001), family income (0.037) and maxillary sinus pneumatization (0.032) were statistically significant. Conclusions In brief, patients with SS showed severe teeth loss, reduced salivary flow, and low educational status. This study addressed important aspects regarding oral findings in SS and highlighted the importance of researches in oral medicine. Key words:Sheehan’s Syndrome, hypopituitarism, tooth loss, salivary flow.

Abstract
Sheehan syndrome or postpartum hypopituitarism is a condition characterized by hypopituitarism due to necrosis of the pituitary gland. The initial insult is caused by massive postpartum haemorrhage (PPH), leading to impaired blood supply to the pituitary gland, which has become enlarged during pregnancy. Small sella turcica size, vasospasms (caused by PPH) and/or thrombosis (associated with pregnancy or coagulation disorders) are predisposing factors; autoimmunity might be involved in the progressive worsening of pituitary functions. Symptoms are caused by a decrease or absence of one or more of the pituitary hormones, and vary, among others, from failure to lactate and nonspecific symptoms (such as fatigue) to severe adrenal crisis. In accordance with the location of hormone-secreting cells relative to the vasculature, the secretion of growth hormone and prolactin is most commonly affected, followed by follicle-stimulating hormone and luteinizing hormone; severe necrosis of the pituitary gland also affects the secretion of thyroid-stimulating hormone and adrenocorticotropic hormone. Symptoms usually become evident years after delivery, but can, in rare cases, develop acutely. The incidence of Sheehan syndrome depends, to a large extent, on the occurrence and management of PPH. Sheehan syndrome is an important cause of hypopituitarism in developing countries, but has become rare in developed countries. Diagnosis is based on clinical manifestations combined with a history of severe PPH; hormone levels and/or stimulation tests can confirm clinical suspicion. Hormone replacement therapy is the only available management option so far.
