A 33-Year-Old Man with Gynaecomastia and Galactorrhea as the First Symptoms of Graves Hyperthyroidism Thu, 01 Dec 2016 13:44:40 +0000 http://www.hindawi.com/journals/crie/2016/1946824/ Graves’ hyperthyroidism has a various number of well-recognized manifestations. Galactorrhea is a rare manifestation in this disease. We describe a 33-year-old man who presented with the symptoms of hyperthyroidism, gynaecomastia, and galactorrhea for 2 months. Physical examination revealed goitre, gynaecomastia, and galactorrhea, bilaterally. Laboratory investigations demonstrated high free thyroxine with suppressed thyroid-stimulating hormone level together with elevated anti-TSH receptor; therefore, the diagnosis of Graves’ disease was confirmed. Other investigations to elucidate the etiology of galactorrhea were normal, so the galactorrhea was hypothesized to be caused by Graves’ disease. The gynaecomastia and galactorrhea resolved with the successful treatment of hyperthyroidism. Although the galactorrhea is extremely rare in thyrotoxicosis male patients, to the best of our knowledge, this is the third case which reported gynaecomastia and galactorrhea in male patient who presented with thyrotoxicosis.

Unusual Cushing’s Syndrome and Hypercalcitoninaemia due to a Small Cell Prostate Carcinoma Thu, 01 Dec 2016 12:09:29 +0000 http://www.hindawi.com/journals/crie/2016/6308058/ A 75-year-old man was hospitalized because of severe hypokalaemia due to ACTH dependent Cushing’s syndrome. Total body computed tomography (TBCT) and 68 Gallium DOTATATE PET/CT localized a voluminous prostate tumour. A subsequent transurethral prostate biopsy documented a small cell carcinoma positive for ACTH and calcitonin and negative for prostatic specific antigen (PSA) at immunocytochemical study; serum prostatic specific antigen (PSA) was normal. Despite medical treatments, Cushing’s syndrome was not controlled and the patient’s clinical condition progressively worsened. Surgical resection was excluded; the patient underwent a cycle of chemotherapy followed by febrile neutropenia and fatal intestinal perforation. This case report describes a rare case of Cushing’s syndrome and hypercalcitoninaemia due to a small cell carcinoma of the prostate, a rare tumour with very few therapeutic options and negative prognosis.

Nodular Lymphocyte Predominant Hodgkin Lymphoma of the Thyroid Thu, 01 Dec 2016 08:09:02 +0000 http://www.hindawi.com/journals/crie/2016/8756723/ Thyroid lymphomas are rare clinical entities that may result from either the primary intrathyroid de novo or secondary thyroid gland involvement of a lymphoma. Among these, the Hodgkin’s subtype is quite uncommon, accounting for 0.6–5% of all thyroid malignancies. The authors report on a 76-year-old female presenting with a thyroid nodule that, upon surgical excision, was found to be a nodular lymphocyte predominant Hodgkin lymphoma of the thyroid. So far, thyroid involvement by this variant has never been reported. Upon reporting on this clinical case, the authors emphasize the difficulties usually found in establishing the diagnosis and in defining the best management strategy. A thorough review of the available literature is done. Carlos Tavares Bello, João Cassis, Helder Simões, and João Sequeira Duarte Copyright © 2016 Carlos Tavares Bello et al. All rights reserved. Patients with Acromegaly Presenting with Colon Cancer: A Case Series Tue, 29 Nov 2016 14:05:21 +0000 http://www.hindawi.com/journals/crie/2016/5156295/ Introduction. Frequent colonoscopy screenings are critical for early diagnosis of colon cancer in patients with acromegaly. Case Presentations. We performed a retrospective analysis of the incidental diagnoses of colon cancer from the ACCESS trial (ClinicalTrials.gov identifier: NCT01995734). Colon cancer was identified in 2 patients (4.5%). Case  1 patient was a 36-year-old male with acromegaly who underwent transsphenoidal surgery to remove the pituitary adenoma. After surgery, the patient underwent routine colonoscopy screening, which revealed a 40 mm tubular adenoma in the descending colon. A T1N1a carcinoma was surgically removed, and 1 of 22 lymph nodes was positive for metastatic disease, leading to a diagnosis of stage 3 colon cancer. Case  2 patient was a 50-year-old male with acromegaly who underwent transsphenoidal surgery to remove a 2 cm pituitary adenoma. The patient reported severe cramping and lower abdominal pain, and an invasive 8.1 cm3 grade 2 adenocarcinoma with signet rings was identified in the ascending colon and removed. Of the 37 lymph nodes, 34 were positive for the presence of tumor cells, and stage 3c colon cancer was confirmed. Conclusion. Current guidelines for colonoscopy screening at the time of diagnosis of acromegaly and at appropriate follow-up intervals should be followed. Murray B. Gordon, Samer Nakhle, and William H.

A Large Isolated Hydatid Cyst of the Adrenal Gland: A Case Report and Review of the Literature Mon, 28 Nov 2016 12:17:56 +0000 http://www.hindawi.com/journals/crie/2016/9237903/ A 44-year-old patient presented with two-year history of (R) lumbar pain. There was a strong history of childhood animals’ contact, including dogs. A brother had multiple hydatid cysts requiring surgery. Initial ultrasound showed a large (R) adrenal mass measuring  cm. Subsequent CT scan confirmed a heavily calcified cyst in the (R) adrenal gland. Hormonal studies were normal. He had an uneventful course following a total adrenalectomy. Isolated adrenal hydatid is extremely rare with an incidence of less than 0.5%; however, the diagnosis should always be suspected in all patients from an endemic area presenting with an adrenal cystic mass.

Short-Term PTH(1-34) Therapy in Children to Correct Severe Hypocalcemia and Hyperphosphatemia due to Hypoparathyroidism: Two Case Studies Sun, 13 Nov 2016 09:39:28 +0000 http://www.hindawi.com/journals/crie/2016/6838626/ The standard treatment of hypoparathyroidism is to control hypocalcemia using calcitriol and calcium supplementation. However, in severe cases this approach is insufficient, and the risks of intravenous (i.v.) calcium administration and prolonged hospitalization must be considered. While the use of recombinant human parathyroid hormone 1-34 [rhPTH(1-34)] for long-term control of hypocalcemia has been established, the benefits of short-term rhPTH(1-34) treatment in children have not been explored. We report two patients with hypoparathyroidism treated with rhPTH(1-34). Patient 1 is a 10-year-old female with polyglandular autoimmune syndrome type 1. Patient 2 is a 12-year-old female with hypoparathyroidism after total thyroidectomy. Both patients showed poor response to i.v. and oral calcium and calcitriol, and patient 1 did not respond to phosphate binders. Patient 1 had rapid increase in serum calcium with a decrease in serum phosphate after a 3-day course of subcutaneous rhPTH(1-34). Patient 2 had normalization of calcium and phosphate levels after a 7-day course of rhPTH(1-34). These cases support a role for rhPTH(1-34) in the acute management of hypoparathyroidism in hospitalized patients to more rapidly correct hypocalcemia and hyperphosphatemia, shorten hospitalization, and reduce the need for frequent i.v. calcium boluses.

Nonislet Cell Tumor Hypoglycemia in a Patient with Adrenal Cortical Carcinoma Thu, 10 Nov 2016 08:20:39 +0000 http://www.hindawi.com/journals/crie/2016/5731417/ Nonislet cell tumor hypoglycemia (NICTH) is a rare but serious paraneoplastic syndrome in which a tumor secretes incompletely processed precursors of insulin-like growth factor-II (IGF-II), causing hypoglycemia. Here, we report an exceptional case of NICTH caused by nonfunctioning adrenocortical carcinoma in a 39-year-old male with recurrent hypoglycemia. The patient’s serum IGF-II/IGF-I ratio had increased to 27.8. The serum level of the IGF-II/IGF-I ratio was normalized after removal of the tumor, and the hypoglycemic attacks no longer occurred after the operation.

The Biochemical Profile of Familial Hypocalciuric Hypercalcemia and Primary Hyperparathyroidism during Pregnancy and Lactation: Two Case Reports and Review of the Literature Wed, 09 Nov 2016 07:43:16 +0000 http://www.hindawi.com/journals/crie/2016/2725486/ Background. Primary hyperparathyroidism (PHPT) and Familial Hypocalciuric Hypercalcemia (FHH) result in different maternal and fetal complications in pregnancy. Calcium to creatinine clearance ratio (CCCR) is commonly used to help distinguish these two conditions. Physiological changes in calcium handling during pregnancy and lactation can alter CCCR, making it a less useful tool to distinguish PHPT from FHH. Cases. A 25-year-old female presented with hypercalcemia and an inappropriately normal PTH. Her CCCR was 0.79% before pregnancy and rose to 1.99% in her second trimester. The proband’s mother and neonate had asymptomatic hypercalcemia. Genetic analysis revealed a CaSR mutation consistent with FHH. A 19-year-old female presented with a history of nephrolithiasis who underwent emergent caesarean section at 29 weeks of gestation for severe preeclampsia. At delivery, she was diagnosed with hypercalcemia with an inappropriately normal PTH and a CCCR of 2.67%, which fell to 0.88% during lactation. Parathyroidectomy cured her hypercalcemia. Pathology confirmed a parathyroid adenoma. Conclusion. These cases illustrate the influence of pregnancy and lactation on renal calcium indices, such as the CCCR. To avoid diagnostic error of women with hypercalcemia during pregnancy and lactation, calcium biochemistry of first-degree relatives and genetic testing of select patients are recommended. S. A.

Surgical Management of Life-Threatening Thyroid Haematoma following Occult Blunt Neck Trauma Tue, 25 Oct 2016 12:45:10 +0000 http://www.hindawi.com/journals/crie/2016/4307695/ A 42-year-old man arrived at the emergency department in severe respiratory distress, requiring immediate intubation and ventilation. An emergency computed tomography (CT) neck scan identified a substantial haematoma within a multinodular goitre, necessitating an emergency total thyroidectomy. It was later discovered that the patient had been the victim of an assault involving blunt trauma to the anterior neck. Five days postoperatively the patient was extubated and was well enough to self-discharge the following day. Pathology revealed the lesion to be a ruptured follicular adenoma within his multinodular goitre. Signs of this rare but life-threatening condition may be subtle on initial presentation, particularly if the patient is obtunded. Patients with suspected blunt neck trauma should be observed for signs of respiratory distress. If this develops, the patient should be intubated to facilitate CT scan, and if thyroid haematoma is confirmed, emergency thyroidectomy is the definitive treatment.

Anterior Pituitary Aplasia in an Infant with Ring Chromosome 18p Deletion Mon, 24 Oct 2016 07:41:40 +0000 http://www.hindawi.com/journals/crie/2016/2853178/ We present the first reported case of an infant with 18p deletion syndrome with anterior pituitary aplasia secondary to a ring chromosome. Endocrine workup soon after birth was reassuring; however, repeat testing months later confirmed central hypopituitarism. While MRI reading initially indicated no midline defects, subsequent review of the images confirmed anterior pituitary aplasia with ectopic posterior pituitary. This case demonstrates how deletion of genetic material, even if resulting in a chromosomal ring, still results in a severe syndromic phenotype. Furthermore, it demonstrates the necessity of close follow-up in the first year of life for children with 18p deletion syndrome and emphasizes the need to verify radiology impressions if there is any doubt as to the radiologic findings.

Moyamoya Disease with Coexistent Hypertriglyceridemia in Pediatric Patient Mon, 24 Oct 2016 07:41:05 +0000 http://www.hindawi.com/journals/crie/2016/7974182/ Moyamoya disease is a rare chronic and progressive cerebrovascular disease of the arteries of the circle of Willis that can affect children and adults. It has been associated with multiple diseases, including immunologic, like Graves’ disease, diabetes mellitus, and SLE. Hyperlipidemia has been recognized in patients with Moyamoya disease with an incidence of 27–37%. However, no case in pediatric patients has been reported of the coexistence of Moyamoya disease and hyperlipidemia. Here we present a case of a 9-year-old female diagnosed with Moyamoya disease after a stroke with incidental finding of familial hypercholesterolemia. This finding will make our patient a very unique case, since there has not been any reporting of Moyamoya disease and hypercholesterolemia association.

Syndrome of Reduced Sensitivity to Thyroid Hormones: Two Case Reports and a Literature Review Wed, 28 Sep 2016 10:24:52 +0000 http://www.hindawi.com/journals/crie/2016/7546453/ Resistance to thyroid hormone (RTH) is an extremely rare dominantly inherited condition of impaired tissue responsiveness to thyroid hormone (TH). Most patients with RTH have mutations in the gene that encodes the β isoform of the receptor of thyroid hormone (THR-β gene). Mutant receptors are unable to activate or repress target genes. The majority of them are asymptomatic or rarely have hypo- or hyperthyroidism. RTH is suspected by the finding of persistent elevation of serum levels of free T3 (FT3) and free T4 (FT4) and nonsuppressed TSH. We present two cases of RTH diagnosed after total thyroidectomy. The first patient was initially diagnosed with primary hyperthyroidism due to toxic multinodular goiter. The second patient had undergone thyroidectomy for multinodular goiter 16 years before diagnosis of RTH. After thyroidectomy, although on relatively high doses of levothyroxine, both of them presented with the laboratory findings of RTH. Genetic analysis revealed RTH.

Occult Langerhans Cell Histiocytosis Presenting with Papillary Thyroid Carcinoma, a Thickened Pituitary Stalk and Diabetes Insipidus Tue, 30 Aug 2016 12:01:57 +0000 http://www.hindawi.com/journals/crie/2016/5191903/ Etiologies of a thickened stalk include inflammatory, neoplastic, and idiopathic origins, and the underlying diagnosis may remain occult. We report a patient with a thickened pituitary stalk (TPS) and papillary thyroid carcinoma (PTC) whose diagnosis remained obscure until a skin lesion appeared. The patient presented with PTC, status postthyroidectomy, and I131 therapy. PTC molecular testing revealed BRAF mutant (V600E, GTC>GAG). She had a 5-year history of polyuria/polydipsia. Overnight dehydration study confirmed diabetes insipidus (DI). MRI revealed TPS with loss of the posterior pituitary bright spot. Evaluation showed hypogonadotropic hypogonadism and low IGF-1. Chest X-ray and ACE levels were normal. Radiographs to evaluate for extrapituitary sites of Langerhans Cell Histiocytosis (LCH) were unremarkable. Germinoma studies were negative: normal serum and CSF beta-hCG, alpha-fetoprotein, and CEA. Three years later, the patient developed vulvar labial lesions followed by inguinal region skin lesions, biopsy of which revealed LCH. Reanalysis of thyroid pathology was consistent with concurrent LCH, PTC, and Hashimoto’s thyroiditis within the thyroid. This case illustrates that one must be vigilant for extrapituitary manifestations of systemic diseases to diagnose the etiology of TPS. An activating mutation of the protooncogene BRAF is a potential unifying etiology of both PTC and LCH. Michael S. Gordon and Murray B. Gordon Copyright © 2016 Michael S. Gordon and Murray B. Gordon.

Bilateral Carotid-Cavernous Fistulas: An Uncommon Cause of Pituitary Enlargement and Hypopituitarism Mon, 29 Aug 2016 09:47:57 +0000 http://www.hindawi.com/journals/crie/2016/6364203/ Carotid-cavernous fistulas (CCFs) are rare, pathologic communications of the carotid artery and the venous plexus of the cavernous sinus. They can develop spontaneously in certain at risk individuals or following traumatic head injury. Typical clinical manifestations include headache, proptosis, orbital pain, and diplopia. We report a case of bilateral carotid-cavernous fistulas associated with these symptoms and also with pituitary enlargement and hypopituitarism, which improved following surgical intervention. Arterialization of the cavernous sinus and elevated portal pressure may interfere with normal venous drainage and the conveyance of inhibiting and releasing hormones from the hypothalamus, resulting in pituitary enlargement and hypopituitarism. This condition should be considered in the differential diagnosis of hypopituitarism associated with anterior pituitary enlargement. Anthony Liberatore and Ronald M.

Mon, 15 Aug 2016 09:18:12 +0000 http://www.hindawi.com/journals/crie/2016/5218985/ Thyroid storm is a life-threatening condition that occurs secondary to an uncontrolled hyperthyroid state. Atrial fibrillation is a cardiovascular complication occurring in up to 15% of patients experiencing thyroid storm, and if left untreated this condition could have up to a 25% mortality rate. Thyroid storm with stroke is a rare presentation. This case report details a left middle cerebral artery (MCA) stroke with global aphasia and thyroid storm in a 53-year-old Hispanic male patient. Although uncommon, this combination has been reported in multiple case series. Although it is well documented that dysfunctional thyroid levels promote a hypercoagulable state, available guidelines from multiple entities are unclear on whether anticoagulation therapy is appropriate in this situation.

A Novel T55A Variant of Gsα Associated with Impaired cAMP Production, Bone Fragility, and Osteolysis Sun, 07 Aug 2016 11:38:05 +0000 http://www.hindawi.com/journals/crie/2016/2691385/ G-protein coupled receptors (GPCRs) mediate a wide spectrum of biological activities. The GNAS complex locus encodes the stimulatory alpha subunit of the guanine nucleotide binding protein () and regulates production of the second messenger cyclic AMP (cAMP). Loss-of-function GNAS mutations classically lead to Albright’s Hereditary Osteodystrophy (AHO) and pseudohypoparathyroidism, often with significant effects on bone formation and mineral metabolism. We present the case of a child who exhibits clinical features of osteolysis, multiple childhood fractures, and neonatal SIADH. Exome sequencing revealed a novel de novo heterozygous missense mutation of GNAS (c.163A<G, p.T55A) affecting the p-loop of the catalytic GTPase domain. In order to further assess whether this unique mutation resulted in a gain or loss of function of , we introduced the mutation into a rat GNAS plasmid and performed functional studies to assess the level of cAMP activity associated with this mutation. We identified a 64% decrease in isoproterenol-induced cAMP production in vitro, compared to wild type, consistent with loss of activity. Despite a significant decrease in isoproterenol-induced cAMP production in vitro, this mutation did not produce a classical AHO phenotype in our patient; however, it may account for her presentation with childhood fractures and osteolysis.

Persistent Primary Hyperparathyroidism, Severe Vitamin D Deficiency, and Multiple Pathological Fractures Mon, 25 Jul 2016 06:50:27 +0000 http://www.hindawi.com/journals/crie/2016/3016201/ Persistent primary hyperparathyroidism (PHPT) refers to the sustained hypercalcemia state detected within the first six months following parathyroidectomy. When it coexists with severe vitamin D deficiency, the effects on bone can be devastating. We report the case of a 56-year-old woman who was sent to this center because of persistent hyperparathyroidism. Her disease had over 3 years of evolution with nephrolithiasis and hip fracture. Parathyroidectomy was performed in her local unit; however, she continued with hypercalcemia, bone pain, and pathological fractures. On admission, the patient was bedridden with multiple deformations by fractures in thoracic and pelvic members. Blood pressure was 100/80, heart rate was 86 per minute, and body mass index was 19 kg/m2. Calcium was 14 mg/dL, parathormone 1648 pg/mL, phosphorus 2.3 mg/dL, creatinine 2.4 mg/dL, urea 59 mg/dL, alkaline phosphatase 1580 U/L, and vitamin D 4 ng/mL. She received parenteral treatment of hypercalcemia and replenishment of vitamin D. The second surgical exploration was radioguided by gamma probe. A retroesophageal adenoma of 4 cm was resected. Conclusion. Persistent hyperparathyroidism with severe vitamin D deficiency can cause catastrophic skeletal bone softening and fractures.

Transient secondary adrenal insufficiency (SAI) is an expected complication following successful adenomectomy of ACTH-secreting pituitary adenomas or unilateral adrenalectomy for cortisol-secreting adrenal adenomas. To date, no pharmacological therapy has been shown to hasten recovery of the hypothalamic-pituitary-adrenal (HPA) axis in this clinical scenario. Case Description. A 33-year-old woman underwent uncomplicated unilateral adrenalectomy for a 3.7 cm cortisol-secreting adrenal adenoma. Postoperatively, she developed SAI and was placed on hydrocortisone 15 mg/day, given in divided doses. In the ensuing six years, the patient’s HPA axis failed to recover and she remained corticosteroid-dependent. Quarterly biochemical testing (after withholding hydrocortisone for 18 hours) consistently yielded undetectable serum cortisol and subnormal plasma ACTH levels. While she was on hydrocortisone 15 mg/day, mifepristone was initiated and gradually titrated to a maintenance dose of 600 mg/day after 5 months. Rapid recovery of the HPA axis was subsequently noted with ACTH rising into the supranormal range at 4 months followed by a subsequent rise in cortisol levels into the normal range. After 6 months, the dose of hydrocortisone and mifepristone was lowered and both were ultimately stopped after 8 months. The HPA axis remains normal after an additional 16 months of follow-up. Conclusion. Mifepristone successfully restored the HPA axis in a woman with prolonged secondary adrenal insufficiency (SAI) after adrenalectomy for Cushing’s syndrome (CS).

Prolactinoma: A Massive Effect on Bone Mineral Density in a Young Patient Thu, 30 Jun 2016 14:18:43 +0000 http://www.hindawi.com/journals/crie/2016/6312621/ This case highlights a prolactinoma in a young male, and its impact on bone health. Osteoporosis has been noted to be an issue in postmenopausal women with prolactinomas. This case shows a similar impact on bone health in a young male resulting in low bone mineral density for age based on -score. This case report highlights the possible mechanisms for the bone loss in the setting of prolactinoma and the need for assessing bone health in such patients. Furthermore it highlights the need for a thorough evaluation in such patients. Scott Sperling and Harikrashna Bhatt Copyright © 2016 Scott Sperling and Harikrashna Bhatt. All rights reserved. Intermittent Fever, Progressive Weight Gain, and Personality Changes in a Five-Year-Old Girl: Unusual Paraneoplastic Syndrome due to Presacral Ganglioneuroma Mon, 20 Jun 2016 07:27:46 +0000 http://www.hindawi.com/journals/crie/2016/2743576/ Ganglioneuromas are rare tumors in the neuroblastoma group. Paraneoplastic syndrome (PNS) due to presacral ganglioneuromas was hardly reported in previous literature. Here, we reported that a case of a 5-year-old girl with a presacral ganglioneuroma presented with PNS, who presented with intermittent fever, progressive weight gain, and personality changes. Our report revealed intermittent fever, progressive weight gain, and personality changes may represent rare paraneoplastic syndromes in ganglioneuromas.

Plurihormonal Cosecretion by a Case of Adrenocortical Oncocytic Neoplasm Thu, 16 Jun 2016 09:13:44 +0000 http://www.hindawi.com/journals/crie/2016/6785925/ Adrenocortical oncocytic neoplasms (oncocytomas) are extremely rare; only approximately 159 cases have been described so far. The majority are nonfunctional and benign. We describe an unusual case of a functional oncocytoma secreting an excess of glucocorticoids (cortisol) and androgens (androstenedione and DHEAS), a pattern of plurihormonal cosecretion previously not reported in men, presenting with endocrine manifestations of Cushing’s syndrome. The neoplasm was considered to be of uncertain malignant potential (borderline) according to the Lin-Weiss-Bisceglia criteria. J. J. Corrales, C. Robles-Lázaro, A. I. Sánchez-Marcos, M. C.

Adrenal Insufficiency under Standard Dosage of Glucocorticoid Replacement after Unilateral Adrenalectomy for Cushing’s Syndrome Tue, 07 Jun 2016 09:54:50 +0000 http://www.hindawi.com/journals/crie/2016/2347528/ Glucocorticoid replacement is needed for patients after adrenal surgery for Cushing’s syndrome; however, the adequate dosage is not easily determined. The patient was a 62-year-old woman who has had hypertension for 5 years and presented with heart failure due to hypertrophic cardiomyopathy. She consulted with us because of general fatigue, facial edema, and muscle weakness and was diagnosed with Cushing’s syndrome. A laparoscopic left adrenalectomy was performed, standard dosage of postoperative replacement was administered, and she was discharged with 30 mg/day of hydrocortisone (cortisol). However, she suffered from loss of appetite and was transferred to an emergency unit with the symptoms of adrenal insufficiency on postoperative day 15. After initial hydrocortisone replacement with 200 mg/day, the dosage was gradually decreased during hospitalization; however, reduction of hydrocortisone dosage lower than 60 mg/day was difficult because of nausea and fatigue. Her circadian cortisol profile after hydrocortisone administration showed delayed and lowered peaks, which suggested that hydrocortisone absorption in the intestine was impaired. Therefore, complicated heart failure may have led to the adrenal insufficiency in the patient. In such cases, we should consider postoperative administration of more than the standard dosage of hydrocortisone to avoid adrenal insufficiency after surgery for Cushing’s syndrome.

A Case of Glucocorticoid Remediable Aldosteronism and Thoracoabdominal Aneurysms Sun, 05 Jun 2016 07:46:03 +0000 http://www.hindawi.com/journals/crie/2016/2017571/ Glucocorticoid remediable aldosteronism (GRA) is rare familial form of primary aldosteronism characterized by a normalization of hypertension with the administration of glucocorticoids. We present a case of GRA and thoracoabdominal aneurysm complicated by multiple aortic dissections requiring complex surgical and endovascular repairs. Registry studies have shown a high rate of intracranial aneurysms in GRA patients with high case fatality rates. The association of thoracoabdominal aneurysms with GRA has not been described, thus far, in literature. Studies have shown that high tissue aldosterone levels concomitant with salt intake have a significant role in the pathogenesis of aneurysms and this may explain the formation of aneurysms in the intracranial vasculature and aorta. The association of GRA with thoracic aortic aneurysms needs to be further studied to develop screening recommendations for early identification and optimal treatment. Also, the early use of mineralocorticoid antagonists may have a significant preventive and attenuating effect in aneurysm formation, an association which needs to be confirmed in future studies.

Recurrent Thyrotoxicosis due to Both Graves’ Disease and Hashimoto’s Thyroiditis in the Same Three Patients Tue, 31 May 2016 13:44:42 +0000 http://www.hindawi.com/journals/crie/2016/6210493/ Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) are the 2 most common autoimmune disease processes affecting the thyroid gland. The relationship between the two is complex and not clearly understood. It has been theorized that HT and GD are 2 separate disease processes due to unique genetic differences demonstrated by genome studies. On the other hand, based on occurrence of both HT and GD in monozygotic twins and within the same family, they have been regarded to represent 2 ends of the same spectrum. This case report describes 3 patients who presented with thyrotoxicosis due to both GD and HT. The initial presentation was thyrotoxicosis due to GD treated with antithyroid medication followed by temporary resolution. They all subsequently experienced recurrence of thyrotoxicosis in the form of Hashitoxicosis due to HT, and then eventually all developed thyrotoxicosis due to GD, requiring radioablation therapy.

Levothyroxine Tablet Malabsorption Associated with Gastroparesis Corrected with Gelatin Capsule Formulation Mon, 16 May 2016 07:46:25 +0000 http://www.hindawi.com/journals/crie/2016/1316724/ Treatment of hypothyroidism with levothyroxine sodium often requires multiple dose adjustments and can be complicated by patients with gastric and intestinal dysfunction that limits absorption. In these cases, doses are often titrated higher than commonly used in clinical practice. Multiple formulations of levothyroxine are currently available and some may be preferred in cases of malabsorption. We report a case of a 42-year-old female who presented with a living unrelated kidney transplant evaluation with myxedema while being treated with levothyroxine sodium tablets. She was noted to have gastroparesis secondary to Type I diabetes mellitus which may have contributed to levothyroxine malabsorption. Changing to a gelatin capsule formulation quickly corrected her thyroid function assays. This case suggests that gastroparesis may affect absorption of levothyroxine tablets and the gelatin capsules may be an effective alternative therapy. David P. Reardon and Peter S.

Cerebral Malaria: An Unusual Cause of Central Diabetes Insipidus Sun, 08 May 2016 11:17:33 +0000 http://www.hindawi.com/journals/crie/2016/2047410/ Central diabetes insipidus is an uncommon feature of malaria. A previously healthy 72-year-old man presented with fever, rigors, and altered mental status after a recent trip to Liberia, a country known for endemic falciparum malaria. Investigations confirmed plasmodium falciparum parasitemia. Within one week after admission, the serum sodium rose to 166 mEq/L and the urine output increased to 7 liters/day. Other labs were notable for a high serum osmolality, low urine osmolality, and low urine specific gravity. The hypernatremia did not respond to hypotonic fluids. Diabetes insipidus was suspected and parenteral desmopressin was started with a prompt decrease in urinary output and improvement in mental status. Additional testing showed normal anterior pituitary hormones. The desmopressin was eventually tapered off with complete resolution of symptoms. Central diabetes insipidus occurred likely as a result of obstruction of the neurohypophyseal microvasculature. Other endocrinopathies that have been reported with malaria include hyponatremia, adrenal insufficiency, hypothyroidism, hypocalcemia, hypophosphatemia, hyper-, and hypoglycemia, but none manifested in our patient. Though diabetes insipidus is a rare complication of malaria, clinicians need to be aware of this manifestation, as failure to do so may lead to fatality particularly if the patient is dehydrated.

Panhypopituitarism due to Absence of the Pituitary Stalk: A Rare Aetiology of Liver Cirrhosis Sun, 24 Apr 2016 06:54:44 +0000 http://www.hindawi.com/journals/crie/2016/9071097/ Studies have established a relationship between hypothalamic-pituitary dysfunction and the onset of liver damage, which may occasionally progress to cirrhosis. Patients with hypopituitarism can develop a metabolic syndrome-like phenotype. Insulin resistance is the main pathophysiological axis of metabolic syndrome and is the causal factor in the development of nonalcoholic fatty liver disease (NAFLD). We present the case of a young patient with liver cirrhosis of unknown aetiology that was finally attributed to panhypopituitarism.

Gigantomastia and Macroprolactinemia Responding to Cabergoline Treatment: A Case Report and Minireview of the Literature Mon, 18 Apr 2016 09:52:52 +0000 http://www.hindawi.com/journals/crie/2016/3576024/ Background. Macroprolactinemia is defined as predominance of high molecular weight prolactin forms in the circulation. Although macroprolactin is considered as a biologically inactive molecule, some authorities suggest treatment in symptomatic cases. Gigantomastia is defined as excess breast tissue and most cases in the literature were treated by surgical intervention. Case. A 44-year-old woman was admitted to our clinic with gigantomastia and galactorrhea. The patient had a demand for surgical therapy. In laboratory examination, she had hyperprolactinemia and macroprolactinemia. Pituitary imaging revealed 6 mm microadenoma in right side of the hypophysis. Since she was symptomatic, cabergolin treatment was started. Macroprolactin became negative, breast circumference decreased significantly, and galactorrhea resolved after treatment. Conclusion. Gigantomastia might be the presenting symptom in patients with macroprolactinemia. In these patients medical treatment with cabergoline may be used initially as an alternative to surgical approach.

Primary Mucosa-Associated Lymphoid Tissue Lymphoma of Thyroid with the Serial Ultrasound Findings Wed, 23 Mar 2016 13:55:39 +0000 http://www.hindawi.com/journals/crie/2016/5608518/ Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) of the thyroid gland is uncommon. Even though its natural history is not well defined, it is known to be indolent course. We present a case of primary MALT thyroid lymphoma with the serial sonographic findings in the patient presenting as the focal nodule. A 45-year-old woman visited our hospital for neck examination. Initially, fine-needle aspiration cytology in the focal hypoechoic lesion in the left thyroid lobe on ultrasound sonography was performed and consistent with Hashimoto’s thyroiditis. However, the results of serial ultrasounds and core-needle biopsy revealed an extranodal marginal zone lymphoma of MALT on 4-year follow-up. Patients with a focal hypoechoic nodule with linear echogenic strands and segmental pattern in the background of Hashimoto’s thyroiditis on ultrasonography should undergo careful surveillance for malignancy. Serial sonographic features in this case are meaningful in the understanding of the natural history of the extranodal marginal zone lymphoma of MALT of the thyroid.

Wed, 23 Mar 2016 12:15:40 +0000 http://www.hindawi.com/journals/crie/2016/1320827/ Patients suffering from multinodular toxic goiter (MNTG) are candidates to thyroidectomy or radioiodine 131I (131I) therapy. Thyroidectomy may be preferable especially when the volume of hyperfunctioning tissue is so large that a single administration of 131I is unlikely to cure the patient in terms of nodule’s volume reduction and thyroid function. We describe the case of a 71-year-old man suffering from thyrotoxic state for the presence of two large hyperfunctioning thyroid nodules. As the patient refused surgery, at first we administered 600 MBq dose of 131I, which was unable to solve hyperthyroidism and local compressive symptoms. Then, before administering another 131I dose, the patient underwent a laser ablation treatment (LAT) in both nodules. After a significant shrinkage due to LAT, the patient received 400 MBq 131I. This procedure was able to definitely cure hyperthyroidism, to induce a significant reduction of nodules’ volume, and to render the patient asymptomatic for compressive symptoms. This case demonstrates that 131I preceded by LAT represents a valid alternative strategy to surgery, even in the presence of two large coexistent hot nodules.
