Cryptococcal meningitis is a critical disease that occasionally involves immunosuppressed patients. We herein report a 79-year-old Japanese man who received low-dose prednisolone therapy for neurosarcoidosis and panhypopituitarism. He presented a 10-day history of a fever and altered mental status. The FilmArray Meningitis/Encephalitis Panel and serum cryptococcal antigen tests were both negative, but the cerebrospinal fluid sample became positive for Cryptococcus neoformans after seven-day incubation. After the diagnosis of cryptococcal meningitis, we successfully treated the patient with a recommended treatment regimen. When an immunocompromised patient presents with a subacute fever accompanying any central nervous symptoms, cryptococcal meningitis should be screened for.

Lymphocytic hypophysitis (LYH) is a rare chronic inflammatory disease characterized by lymphocytic infiltration of the anterior or posterior pituitary gland and hypothalamus. LYH is subdivided into lymphocytic adenohypophysitis (LAH), lymphocytic infundibulo-neurohypophysitis (LINH), and lymphocytic panhypophysitis (LPH) depending on the primary site. Most cases occur in adults, with few cases reported in children, and it is especially important to distinguish LYH from suprasellar malignancies, such as germ cell tumors and other neoplastic diseases. Although a biopsy is necessary for definitive diagnosis, it is desirable to be able to diagnose the disease without biopsy if possible, especially in children, because of the surgical invasiveness of the procedure. Recently, serum anti-rabphilin-3A antibodies have attracted attention as diagnostic markers for LYH, especially in LINH, but there are only a few reports on pediatric patients. In the present study, we experienced two children with LPH and LAH, respectively, who tested positive for anti-rabphilin-3A antibodies. This is the first report of children with LYH other than LINH positive for anti-rabphilin-3A antibodies, and anti-rabphilin-3A antibodies may be a useful non-invasive diagnostic marker not only for LINH but also for LYH in general. We also discuss the sensitivity and specificity of anti-rabphilin-3A antibody testing in cases where histological diagnosis has been made.

Review
BACKGROUND
Pituitary stalk interruption syndrome (PSIS) is a congenital disease commonly found in patients with combined pituitary hormone deficiency (CPHD). Most PSIS patients manifest growth retardation and delayed puberty. We report a rare case of PSIS with tall stature, liver cirrhosis and diabetes, possibly caused by an inactivating gene mutation.
CASE PRESENTATION
A 37-year-old female patient initially presented with liver cirrhosis and diabetes, without any secondary sexual characteristics. Endocrine investigation indicated CPHD. Small anterior pituitary, invisible pituitary stalk and no eutopic posterior lobe hypersignal in the sella turcica viewed in magnetic resonance imaging (MRI) confirmed the diagnosis of PSIS. Despite receiving no growth hormone or sex hormone therapy, she reached a final height of 186 cm. Liver histopathology revealed nonalcoholic fatty cirrhosis. Genetic testing identified a heterozygous p.Arg301Cys mutation in the gene.
CONCLUSION
This is a rare case of PSIS with liver cirrhosis and diabetes associated with an inactivating gene mutation. It's supposed that early hyperinsulinism caused by the gene mutation, as well as delayed epiphyseal closure due to estrogen deficiency, contributed to the patient's exceptionally tall stature. Untreated growth hormone deficiency (GHD) resulted in increased visceral fat, leading to nonalcoholic fatty liver disease (NAFLD) and cirrhosis. The decline in β cell function with age, combined with NAFLD, may have played a role in the development of diabetes.

OBJECTIVE
Hypothalamic dysfunction is a rare condition and can be encountered in patients who have been diagnosed or treated for a suprasellar brain tumor. Due to its rarity, the signs and symptoms of hypothalamic dysfunction may be difficult to recognize, leading to delayed diagnosis of the suprasellar brain tumor or to difficulties in finding the health-care expertise for hypothalamic dysfunction after tumor treatment. To improve the care and outcome of patients with acquired hypothalamic dysfunction, professionals are required to understand the patient's needs.
DESIGN
A worldwide online survey was distributed from April 2022 to October 2022 to patients with childhood-onset hypothalamic dysfunction (as reported by the patient) following a brain tumor.
METHODS
Patients were notified about the survey through patient advocacy groups, the SIOPe craniopharyngioma working group and the Endo-ERN platform.
RESULTS
In total, 353 patients with hypothalamic dysfunction following craniopharyngioma (82.2%), low-grade glioma (3.1%) or a pituitary tumor (8.2%) or caregivers responded to the survey. Sixty-two percent had panhypopituitarism. Obesity (50.7%) and fatigue (48.2%) were considered the most important health problems. Unmet needs were reported for help with diet, exercise and psychosocial issues. Patients' suggestions for future research include new treatments for hypothalamic obesity and alternative ways for hormone administration.
CONCLUSIONS
According to the patient's perspective, care for acquired hypothalamic dysfunction can be improved if delivered by experts with a holistic view of the patient in a multidisciplinary setting with a focus on quality of life. Future care and research on hypothalamic dysfunction must integrate the patients' unmet needs.
SIGNIFICANCE STATEMENT
Patients with hypothalamic dysfunction may experience a variety of symptoms, which are not always adequately recognized or addressed. In previous papers, the perspective of caregivers of children with craniopharyngioma has been reported (Klages et al. 2022, Craven et al. 2022). Now we address the patients' perspective on acquired hypothalamic dysfunction using an Endo-ERN global survey. According to the patients' perspective, care can be improved, with needs for improvement in the domains of obesity, fatigue and lifestyle. Research may focus on ways to improve hypothalamic obesity and alternative ways for hormone administration. Ideally, care should be delivered by doctors who have a holistic view of the patient in a multidisciplinary expert team. The results of this study can be used to formulate best practices for clinical care and to design future research proposals.

Combined pituitary hormone deficiency (CPHD) is a rare disorder caused by a complete absence of the anterior pituitary gland hormones. The Dental manifestation, managmnet and two-year-follow-up of a case of a 12-year-old patient with CPHD is reported in this paper. A 12-year-old male patient with medical history of congenital CPHD and vitamin D deficiency presented for dental treatment. The patient looked tired and younger than his chronological age. Intraoral examination revealed good oral hygiene, generalized edematous gingiva, physiological pigmentation and high maxillary labial frenum attachment. The occlusion examination, showed class I molars, 2 mm overjet and 90% overbite. Single anterior tooth #21 crossbite with 1.5 mm diastema. Also, Miller's class I recession in tooth #31 with a probing depth of 1 mm, and grade I mobility. The treatment plan was formulated in phases, and the primary physician consultation was obtained and a clearance for dental treatment with a recommendation to double the hydrocortisone dose before a stressful dental procedure was recommended. Preventive and restorative programs were planned and provided. Then, the lower lingual holding arch was provided after the extraction of mandibular primary canines with composite turbo, and tooth #21 crossbite was corrected using a nance appliance with Z spring. Finally, the patient was recommended to attend follow-up visits every three months. During which the preventive program was reinforced and the restorative treatments were reevaluated. At the 2-year-follow-up satisfactory and stable aesthetic and functional results were obtained. This report highlights the oral manifestations, the value of establishing a preventive program, and restorative, and orthodontic interventions among patients with CPHD.

INTRODUCTION
Sheehan's syndrome (SS) is a rare cause of hypopituitarism resulting from postpartum haemorrhage and pituitary necrosis. It remains an underdiagnosed condition, especially in developing countries due to poor obstetric care and home deliveries. This case report highlights the significance of recognizing atypical presentations of SS, such as pancytopenia, to aid in early diagnosis and management.
CASE PRESENTATION
A 40-year-old female presented with acute abdomen symptoms and was initially diagnosed with acalculous cholecystitis. However, a detailed history revealed a history of postpartum haemorrhage 18 years prior, leading to a provisional diagnosis of SS. Further investigations confirmed panhypopituitarism, including hypothyroidism, hypocortisolism, and hypogonadism. Notably, the patient also exhibited pancytopenia, a rarely reported haematological manifestation of SS.
DISCUSSION
SS often presents with nonspecific symptoms, leading to delayed or missed diagnoses. In this case, the patient's initial presentation of acute abdomen symptoms was attributed to secondary adrenal insufficiency due to panhypopituitarism. The presence of pancytopenia, along with hyponatremia, further complicated the clinical picture. Hormone replacement therapy led to a remarkable improvement in the patient's condition, emphasizing the importance of early diagnosis and intervention.
CONCLUSION
SS is a common cause of panhypopituitarism in developing countries, but its atypical presentations, such as pancytopenia, are rare and often overlooked. This case highlights the need for increased awareness among clinicians to consider SS in patients with unexplained haematological abnormalities, particularly in regions with high rates of postpartum haemorrhage. Early recognition and appropriate hormone replacement therapy can significantly improve patients' outcomes and prevent long-term complications associated with this underdiagnosed syndrome.

UNLABELLED
Munchausen syndrome is known as a factitious disorder imposed on the self. Factitious Cushing's syndrome (CS) is a very rare form of Munchausen syndrome, presenting with varied clinical and biochemical features, making diagnosis challenging.
CASE PRESENTATION
A 40-year-old female patient who worked as a registered nurse presented with clinical features of CS but denied any exogenous corticosteroid use. The endocrine workup revealed that the patient had a high 24 h urinary-free cortisol collection before admission. Subsequent evaluations showed low levels of morning cortisol and plasma adrenocorticotropic hormone along with a suppressed overnight low-dose dexamethasone suppression test, leading to an investigation of hypercortisolism. Unexpectedly, subsequent testing showed a normal 24 h urinary-free cortisol level. Additionally, the patient was diagnosed with panhypopituitarism, the radiological investigations showed normal pituitary and adrenal glands. Despite consistently denying the use of corticosteroids, it was finally discovered that the patient had been surreptitiously taking prednisone and receiving multiple dexamethasone injections over the past few months. The patient received treatment through a gradual prednisone tapering regimen, accompanied by comprehensive psychiatric evaluation and management.
CONCLUSION
This case underscores the exceptional rarity of factitious CS and emphasizes the importance of considering it as a potential differential diagnosis in hypercortisolism cases, particularly when the patient's medical history contradicts investigative findings. Furthermore, it highlights the criticality of adopting a multidisciplinary approach to investigate patients whose clinical presentation aligns with factitious CS.

Chondromas are rare benign tumors composed of hyaline cartilage that can arise in various locations in the body. Their occurrence in the clivus, leading to panhypopituitarism, is exceptionally rare. This case report describes a 93-year-old female with a known clival chondroma who presented with altered mental status, presumed to be secondary to toxic metabolic encephalopathy due to an infectious cause. Further diagnostic evaluation revealed pituitary hormone levels below the normal range. This case report aims to highlight a unique case of panhypopituitarism attributed to a chondroma in the clivus with tumor extension to the sellar region, emphasizing the diagnostic challenges and treatment options for this unusual pathology.

Post-traumatic pituitary stalk transection syndrome (PSTS) expeditiously manifested after a fall from a height combined with acute traumatic spinal cord injury: a rare case report with review of literature.
Post-traumatic pituitary stalk transection syndrome (PSTS) is an extremely rare cause of combined pituitary hormone deficiency (CPHD), affecting approximately 9 per 100,000 cases of traumatic brain injury. In contrast, pituitary stalk interruption syndrome (PSIS) is also a rare cause of CPHD. Importantly, these conditions are often confused due to their similar names and resembling findings on magnetic resonance imaging (MRI). PSIS has been thought to be a prenatal developmental event resulting from a couple of genetic aberrations. In typical PSIS, anterior pituitary hormone deficiencies are restricted to growth hormone (GH) and gonadotropin during the pediatric age, gradually and generally progressing to panhypopituitarism in most cases. In contrast, global deficiencies of the anterior pituitary hormones in PSTS are temporally associated with trauma. To the best of our knowledge, no case reports of PSTS combined with acute traumatic spinal cord injury have been reported. A 34-year-old female was transferred to our hospital after jumping from the fourth building floor. She was diagnosed as an acute traumatic spinal cord injury and underwent the operation of elective posterior spinal fusion. On postoperative day 7, the blood tests revealed considerable hyperkalemia, hyponatremia and eosinophilia. Notably, menstruation stopped after falling from a height. Pituitary function tests revealed GH deficiency, hypogonadism, hypothyroidism and hypoadrenocorticism. MRI revealed loss of the pituitary stalk, whilst the hyperintense signal from distal axon of hypothalamus was still identified. Based on these findings, she was diagnosed as PSTS. Our case highlights endocrinological landscape of transection of the pituitary stalk by acute trauma.
