BACKGROUND Craniopharyngioma is a rare, partly cystic embryonic malformation of the sellar and parasellar region and is usually benign. This report is of a 55-year-old woman presenting with a second diagnosis of craniopharyngioma following diagnosis and successful treatment of craniopharyngioma as a 5-year-old child. CASE REPORT Our patient was diagnosed with craniopharyngioma at age 5 when she presented with headaches accompanied by nausea and vomiting, decreased visual acuity, polyurea, and polydipsia for 6 months. She was found to have diplopia and grade II papilledema. A skull X-ray showed separation of the sutures and a calcified mass in the suprasellar region. A pneumoencephalogram showed extension of the tumor into the third ventricle. Surgery was performed via transcallosal approach followed by radiotherapy at 5000 rays. She was followed up clinically and radiologically and had been disease-free until age 55, when she presented with headache and facial numbness. On examination, she had right-eye Horner syndrome, decreased sensation in the right side of the face, diplopia, and grade 2 facial palsy. An MRI revealed interval significant recurrence of the craniopharyngioma at the sellar/suprasellar mass with extension to the right Meckel's cave and the right posterior fossa. On April 6, 2023, she underwent surgical resection through a right-sided craniotomy and Kawase approach. This was followed by CyberKnife radiation therapy. CONCLUSIONS This report has presented a rare recurrence of craniopharyngioma with a 50-year interval and has highlighted the challenges in the diagnosis and the multidisciplinary approach to patient diagnosis and management.

Annals of Medicine and Surgery (2012) Jun 2024Bartter syndrome is an autosomal recessive salt reabsorption disorder that results in decreased extracellular fluid volume with low/normal blood pressure.
BACKGROUND
Bartter syndrome is an autosomal recessive salt reabsorption disorder that results in decreased extracellular fluid volume with low/normal blood pressure.
CASE PRESENTATION
A 17-year-old boy with polydipsia, polyuria, weakness in the lower limbs, and ataxic gait. His Laboratory test shows hypokalemia; hypochloremia, hypomagnesemia and metabolic alkalosis. The authors' patient was managed by fluid and electrolyte replacement, which is essential in emergency management.
CONCLUSION
Bartter syndrome is difficult to treat, and currently, there is no complete cure. The overall prognosis depends on the extent of receptor dysfunction, and despite these facts, most patients can live a normal life if they strictly follow their treatment plan.

The Significance of Precise Diabetes Diagnosis: A Case of Euglycemic Diabetic Ketoacidosis Induced by the Introduction of Empagliflozin with Simultaneous Reduction of Insulin Dosage.
UNLABELLED
Euglycemic diabetic ketoacidosis (euDKA) is a rare but severe metabolic complication of diabetes mellitus characterised by elevated anion gap metabolic acidosis despite normal or mildly elevated blood glucose levels. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have emerged as effective antidiabetic medications, yet their use is associated with an increased risk of euDKA, especially when coupled with insulin dose reduction. We present the case of a 50-year-old male with a 20-year history of diabetes mellitus, initially managed with insulin and metformin, who developed euDKA following the introduction of empagliflozin and sitagliptin alongside a reduction in insulin therapy. Despite normoglycaemia the patient exhibited symptoms of ketoacidosis, including chronic fatigue, polydipsia, and polyuria. Diagnostic workup revealed metabolic acidosis, elevated inflammatory markers, acute kidney injury and ketonuria. Subsequent specialised laboratory tests confirmed type 1 diabetes mellitus (T1DM) with the presence of anti-glutamic acid decarboxylase (anti-GAD) antibodies and the absence of C-peptide secretion. Management involved fluid therapy, intravenous insulin and glucose administration. This case underscores the diagnostic challenges of euDKA and emphasises the importance of differentiating between T1DM and T2DM, as management strategies vary significantly. Patient education on insulin therapy and injection techniques is crucial to prevent complications such as improper insulin delivery and dose reduction, which can precipitate euDKA. In conclusion, clinicians should be vigilant for euDKA in patients on SGLT2 inhibitors, particularly when insulin dose reduction is involved. Comprehensive patient education and accurate differentiation between diabetes types are essential for timely diagnosis and optimal management, thereby reducing the risk of severe complications.
LEARNING POINTS
The reduction in insulin doses combined with the introduction of an SGLT2 inhibitor in a patient with type 1 diabetes may lead to the development of a dangerous health complication known as euglycemic diabetic ketoacidosis.In cases of diagnostic uncertainty regarding the differentiation of diabetes types, measuring the levels of C-peptide and anti-GAD antibodies can be helpful.Abnormal glycaemic results in a patient using insulin may result from improper administration. During follow-up visits, it is worthwhile to check the subcutaneous tissue for lipodystrophy and also remind the patient about the necessity of rotating insulin injection sites.

An 11-year-old male child who presented with increased frequency of urination, thirst and feeling of incomplete void was initially diagnosed with diabetes mellitus (DM) based on elevated blood sugar. Polyuria and polydipsia were confirmed even after normalisation of blood sugar. A standardised water deprivation test showed presence of central diabetes insipidus (DI) and patient was started on desmopressin. Presence of DM and DI led to suspicion of DIDMOAD/Wolfram syndrome and ophthalmic examination confirmed bilateral optic atrophy. Despite treatment for DM and DI the urinary complaints persisted, and ultrasound showed persistent bilateral hydronephroureterosis. Bladder workup including voiding cystourethrography (VCUG) and urodynamic study reported thickened trabeculated bladder wall along with overactivity, poor compliance and high bladder pressure. Bladder dysfunction has been documented to be associated with Wolfram syndrome and often may lead to chronic kidney disease which can be prevented by early diagnosis and appropriate management. The case highlights the need for comprehensive evaluation of children with urinary symptoms.

Lymphoma represents up to 30% of neoplasms diagnosed in cats. Diagnosis of lymphoma in the urinary system by examination of urine sediment has been described in a dog, but apparently not previously in cats. Concurrent samples of serum, EDTA whole blood, and urine were submitted from a 15-year-old spayed female domestic shorthair cat exhibiting weight loss, polyuria, and polydipsia. Hematology and biochemical abnormalities included a mild normocytic, normochromic, non-regenerative anemia; an inflammatory leukogram; and azotemia. Urinalysis evaluation revealed inadequate urine concentration and marked proteinuria. Wet-mount urine sediment examination revealed moderate numbers of leukocytes and erythrocytes. A uniform population of intermediate-to-large lymphocytes was observed on a fresh, Wright-Giemsa-stained preparation from cytocentrifuged urine. The cat was euthanized and necropsy was completed. Bilateral renomegaly was identified and characterized by multifocal, pale-yellow, coalescing, poorly defined, homogenous nodules. Microscopically, these nodules were composed of dense sheets of CD3-positive round cells, consistent with T-cell renal lymphoma. Key clinical message: Lymphoma is a common neoplasm in cats that can affect many organ systems, including the upper urinary tract. This case represents an uncommon method of identifying neoplastic lymphocytes evaluation of cytocentrifuged urine, and emphasizes the benefits of examining Romanowsky-stained urine sediment in animals.

Pituitary infiltration by systemic lymphoma is an exceedingly rare occurrence. Given its high mortality rate, it is crucial to recognize its clinical, biochemical and radiological features in order to provide timely intervention. We present the case of a 26-year-old male with a history of human immunodeficiency virus (HIV) infection who presented to the hospital with severe anemia, persistent fever, weight loss and diarrhea over the previous 4 months. Physical examination revealed a compromised general condition, fever, pallor, hepatomegaly and lymphadenopathy. Cervical lymph node biopsy confirmed Burkitt lymphoma (BL). During hospitalization, the patient developed polyuria, polydipsia, hypernatremia, fluid-resistant hypotension and hypoglycaemia. Corticosteroid therapy was initiated due to suspected adrenal insufficiency, resulting in clinical improvement but exacerbation of polyuria and hypernatremia. Plasma and urinary osmolarity confirmed arginine vasopressin deficiency, and assessment of anterior pituitary reserve revealed hypopituitarism, necessitating hormonal replacement therapy. Sellar magnetic resonance imaging with contrast revealed pituitary infiltration. The patient subsequently developed septic shock and died. BL accounts for approximately 10% of the cases of pituitary infiltration associated with lymphoma. Clinical presentation is heterogeneous, with panhypopituitarism often serving as the initial manifestation. Sellar magnetic resonance imaging plays a pivotal role in the differential diagnosis. Management typically entails chemotherapy, immunotherapy, radiation and hormonal replacement therapy. This case report describes a patient with BL and HIV infection who developed panhypopituitarism due to pituitary infiltration, an exceedingly rare presentation considered a medical emergency.

Arginine vasopressin deficiency (AVP-D), formerly known as central diabetes insipidus, is a disease characterized by polyuria, polydipsia, and hypernatremia. The concomitant diagnosis of acute myeloid leukemia (AML) is an underappreciated event that requires prompt recognition and treatment by practicing nephrologists and hematologists. This report highlights this importance by describing the case of a 39-year-old patient newly diagnosed with AML who developed severe hypernatremia. The role of diagnostic testing through desmopressin (DDAVP) challenge and copeptin testing to confirm the diagnosis of AVP-D in this context and the use of DDVAP for treatment are discussed. Practicing nephrologists and primary care providers taking care of patients with similar symptoms will benefit from understanding the pathophysiology of AVP-D, its relationship with AML, and the prognosis in this patient cohort.

Autoimmune hypophysitis (AH) is an uncommon condition where there is inflammation of the pituitary gland which leads to hormonal imbalances. It is often associated with autoimmune diseases; however, a case is yet to be reported with an association of AH with seronegative rheumatoid arthritis (RA). We present a case of a 45-year-old female who complained of polyuria/polydipsia and rapid weight gain. An MRI of the head revealed enlargement of the pituitary gland, concerning for AH. Although she was initially treated for diabetes insipidus, she began reporting new complaints of joint pains and morning stiffness. She was clinically diagnosed with seronegative RA and improved with a trial of hydroxychloroquine. A repeat MRI showed improvement in the abnormal pituitary findings, and the patient was closely monitored with a multidisciplinary approach. Diagnosing and managing patients with AH are topics that are still being explored and researched as it is a relatively rare pathology. Consequently, we found the need to discuss the relationship of AH with seronegative RA and delve into the various diagnostic and treatment approaches.

UNLABELLED
Hypertriglyceridemia (HTG)-induced acute pancreatitis (AP) secondary to insulin deficiency following the onset of type 1 diabetes mellitus (T1DM) is a rare but serious complication in children.
OBJECTIVE
To describe the diagnosis and treatment of severe HTG and to emphasize the need for timely diagnosis of T1DM.
CLINICAL CASE
A 15-year-old female adolescent with a history of overweight presented with a two-weeks history of fever, anorexia, and diffuse abdominal pain. Laboratory tests revealed triglycerides of 17,580 mg/dL, lipase of 723 U/L, and blood glucose of 200 mg/dL. An abdominal CT scan showed an enlarged and edematous pancreas. She was hospitalized with a diagnosis of AP and severe HTG, which progressed to acute necro-hemorrhagic pancreatitis. Treatment included continuous intravenous insulin infusion until triglyceride levels decreased. Upon discontinuation of insulin, fasting hyperglycemia (206 mg/dL) and metabolic acidosis recurred, therefore DM was suspected. Upon targeted questioning, a history of polydipsia, polyuria, and weight loss during the last 3 months stood out. Glycated hemoglobin was markedly elevated (14.7%). Insulin therapy was optimized, achieving stabilization of laboratory parameters after 15 days of treatment and complete anatomical resolution of pancreatic involvement at one year of follow-up.
CONCLUSIONS
The presence of severe HTG in pediatrics compels us to consider its secondary causes, such as the onset of T1DM. It is crucial to improve the ability to diagnose T1DM early, as it may present with infrequent and high-risk presentations for the patient.
