Introduction: Bladder cancers are common malignancies worldwide, and histological examination is the cornerstone of diagnosis and management of these tumours. There exists huge interobserver variability in grading of urothelial carcinoma, furthermore supercial biopsies and cautery effect also effect tumour staging. Pathological grading, staging and their correlation with molecular markers like p53 and Ki-67 might better predict patient outcome and play signicant role in designing the management protocols of these patients. Thus, we aimed to study the role of p 53 and Ki-67 as prognostic and diagnostic biomarkers of urothelial carcinoma in south east Indian population. This was a Methods: prospective study that included 46 patients with Urothelial carcinoma of the urinary bladder. The histopathological evaluation of the tumor tissue was performed to assess the grade and stage of the tumor and was further correlated with important demographic details and with immunohistochemical expression of p 53 and Ki-67. The mean age was 55 and 65 years Results: for male and female patients respectively. Haematuria was the most common presenting symptom. A total of 38 (74%) patients had high-grade tumors. p T2 stage disease was observed in 60% patients. High expression of p 53 expression was noted in 52% of total cases, of which 85% of cases had high grade morphology and 66% were p T2 stage tumours. High expression of p 53 was also noted in 45% of p T1 tumors. Ki-67 showed high expression in 82.6 % of cases; 94% of which were high-grade and 25% were low-grade cases. Although males have preponderance for Conclusion: afiction, but in our country, females also show higher incidence of urothelial carcinoma as compared to published literature. In addition, patients in Indian population present with higher stage disease. p 53 and Ki-67 are biomarkers of higher stage and grade disease, however additional factors also play a denite role in tumour progression and thus in patient outcome

Hypopituitarism, which refers to insufficiency of one or more hormones of the pituitary, can be due to myriad causes. The clinical and radiological spectrum of the condition is heterogeneous, based on the patient’s age, gender, clinical setting, and/or other past medical history. Hypopituitarism includes central hypocortisolism, hypothyroidism, hypogonadism, and growth hormone deficiency. Both hypo- and hyperprolactinemia can be associated with hypopituitarism, with low prolactin signifying more extensive pituitary damage. Posterior pituitary insufficiency (arginine vasopressin deficiency) occurs either in isolation or with anterior pituitary hormone deficiency. Clinical symptomatology of hypopituitarism is usually nonspecific and insidious in onset and progression. Overall, the most common cause of hypopituitarism is a pituitary adenoma and/or its management (surgery, radiotherapy, pharmacotherapy, or a combination of these). However, it is this subset of patients which is more likely to be identified and managed in a timely manner, possibly alleviating the premature mortality associated with hypopituitarism. What is more challenging is the recognition of hypopituitarism in less common settings, which may be either due to direct involvement of the pituitary (infection, traumatic brain injury, or infiltrative causes) or indirectly as a consequence of the primary process (thalassemia, vasculotoxic snakebite, subarachnoid hemorrhage). These entities are often under-recognized, and increased awareness can help in greater recognition of the burden. Further, pituitary insufficiency in most of these settings is dynamic and may progress, or rarely, show recovery of function. This renders complexity to the problem, but makes it even more imperative to suspect, screen, and appropriately manage patients with less common causes of hypopituitarism.

Primary hyperparathyroidism (PHPT) in India is mostly symptomatic with renal and skeletal complications. Evidence on mortality outcomes following parathyroidectomy from India, where the disease is predominantly symptomatic is limited. This was a prospective study to evaluate mortality outcomes in the Indian PHPT registry over the past 25 years (n = 464). Pre- and postoperative parameters and mortality data were obtained from medical records and/or by verbal autopsy, a method validated by WHO for data collection in settings where several deaths are noninstitutional. Patients were divided into survivor (SG) and nonsurvivor groups (NSG) to ascertain differences in presentation and the effect of parathyroidectomy. The overall mortality was 8.8% at a median follow-up of 8 years (IQR 1–13) after parathyroidectomy. Chronic kidney disease was the most common background cause of death (43.5%), followed by pancreatitis (28.2%). NSG had significantly more frequent renal dysfunction (91.9% vs 73.9%), anaemia (50 vs 16.6%) and pancreatitis (24.3 vs 6.4%). PTH (61.9 vs 38.3 pmol/l) and baseline creatinine (97.2 vs 70.7 µmol/l) were significantly higher and eGFR lower (66.7 vs 90.7 ml/min/1.73m2) in the NSG than SG. By Cox proportional modelling, renal dysfunction [HR 2.88 (1.42–5.84)], anaemia [HR 2.45 (1.11–5.42)] and pancreatitis [HR 2.65 (1.24–5.66)] on univariate and renal dysfunction [HR 3.33 (1.13–9.77)] on multivariate analysis were significant for mortality. Survival curves demonstrated a significantly higher mortality with lower eGFR values. Nonsurvivors in PHPT had greater prevalence and more severe baseline renal dysfunction than survivors. Survival after parathyroidectomy was significantly associated with estimated glomerular filtration rate at baseline.

Purpose: Nelson’s syndrome (NS) is regarded as an aggressive complication of total bilateral adrenalectomy (TBA) for Cushing’s disease (CD). This challenge may be addressed by using clinical criteria to guide frequency of neuroimaging to enable timely management of NS and also avoid unnecessary frequent imaging. Methods: All patients (n = 43) with CD subjected to TBA over 35 years at a tertiary care centre were included. NS was defined as a newly appearing or expanding (> 2 mm) pituitary adenoma with or without ACTH levels exceeding 500 pg/ml. Pre-and post-TBA parameters like clinical symptomatology, cortisol, ACTH and radiology were analysed for the prediction of NS. Results: NS developed in 39.5% (n = 17) patients with a median follow-up of 7 years. Half of them had new appearance, while rest had an expansion of pre-existing pituitary tumour. Majority (90%) had ACTH above 500 pg/ml. On Cox proportional hazards analysis, frequent discriminatory features of protein catabolism (≥ 4) (HR 1.15, CI 0.18, 7.06), proximal myopathy (HR 8.82, CI 1.12, 69.58) and annual ACTH increment of 113 pg/ml (HR 12.56, CI 1.88, 88.76) predicted NS. First post-operative year ACTH indices predicting NS included ACTH rise of 116 pg/ml and absolute ACTH of 142 pg/ml (sensitivity, specificity exceeding 90%). Annual ACTH increment exceeding 113 pg/ml, ≥ 4 discriminatory features and uncontrolled hypertension had the best overall prediction. Conclusion: Patients who developed NS had higher rebound rise of ACTH following TBA and a more severe disease phenotype at baseline. Consistent ACTH increment can be used as a marker for predicting the development of NS.

Wolfram syndrome (WFS) is a rare, monogenic neurodegenerative syndrome characterised by insulin requiring non-autoimmune diabetes mellitus (DM) and optic atrophy which are usually the earliest and commonest manifestations. However, there are other features which are under-recognized, adding to morbidity and premature mortality in these patients. Five patients (three males, two females) with genetically confirmed WFS at a single tertiary care centre were prospectively followed up. Their symptomatology, clinical profile, genetic analysis and radiology were analyzed. Multidisciplinary approach was used for comprehensive clinical care of this cohort. Patients with primary gonadal failure were subjected to biopsy and immunohistochemistry (IHC) for wolframin was performed. DM was the earliest presenting manifestation at 6.2 ± 1.3 years followed by optic atrophy at 10.4 ± 2.3 years, diabetes insipidus at 12 ± 2.1 years and deafness at 12.8 ± 2.1 years. All patients were autoantibody negative with low C-peptide(

Paediatric pituitary adenomas (PPAs) are uncommon, with evidence confined to small cohorts.We aimed to elucidate the baseline profile and outcomes of PPAs in a large, contemporary, monocentric cohort.Pituitary clinic at PGIMER over 8 years (2010-2018).PPAs in patients (≤20 years at diagnosis) were included. A retrospective review of their baseline clinico-biochemical and radiological profiles and outcomes post pituitary surgery/medical management was performed.There were a total of 74 patients, of which 42 were female. The median age was 15 (IQR 13-18) years. Corticotropinomas (32.4%) and somatotropinomas (25.7%) were common, with 1 case of TSHoma and pituitary blastoma. The most common presentation was headache (57%) overall and menstrual irregularities (64.2%) in girls. Most (78%) had macroadenomas. Prolactinomas showed an excellent response to primary medical therapy (83.3%). Transsphenoidal surgery was performed in 81% of patients. Diabetes insipidus (30%) and hyponatremia (26.7%) emerged as common postoperative complications. Adjuvant medical management was required in 25%, and radiotherapy in 18%. Remission rates in Cushing's and acromegaly were 62.5% and 57.8%, respectively, with long-term hormone deficits noted in one-third of patients.PPAs have unique features and management challenges, including effects on growth and puberty. Functional tumours and macroadenomas are common. Remission can be achieved in more than half of the patients, with endocrine deficits persisting in about a third of cases, needing long-term surveillance.

Idiopathic gynecomastia is a diagnosis of exclusion. We aimed to evaluate the role of steroids, peptides and growth factors in these patients. Those with bilateral idiopathic gynecomastia (n = 29) (Simon's grade IIb or III) who underwent gland excision were evaluated by immunohistochemical techniques using semi-quantitative grading for oestrogen receptor (ER), progesterone receptor (PR), aromatase, androgen receptor (AR), peptides (IGF-1, IGF-2, HER-2, parathyroid-hormone related peptide [PTHrP]) and growth factors (EGFR, TGFβ). The cohort comprised 29 patients, with a mean age of 25.3 ± 5.1 years and a mean body mass index of 27.2 ± 2.3 kg/m

BACKGROUND: Camurati-Engelmann disease (CED) is a rare bone dysplasia characterized by diffuse diaphyseal osteosclerosis. Skull base involvement in CED can result in hypopituitarism but is seldom reported. Our objective was to report a patient with acquired hypopituitarism due to CED and assess the management challenges. CASE REPORT: A 20-year-old boy presented with lower limb pain. He had walking difficulty in childhood, which was diagnosed as CED and managed with prednisolone. He later discontinued treatment and was lost to follow-up. Current re-evaluation showed short stature (-3.6 standard deviation), low weight (-4.3 standard deviation), and delayed puberty with delayed bone age (13 years). He was found to have secondary hypogonadism (luteinizing hormone level, 0.1 mIU/mL [1.7-8.6 mIU/mL]; follicle-stimulating hormone level, 1.0 mIU/mL [1.5-12.4 mIU/mL]; and testosterone level, 0.087 nmol/L [9-27 nmol/L]), growth hormone deficiency (low insulin-like growth factor I level, 120 ng/mL [226-903 ng/mL] and peak growth hormone level of 7 ng/mL on insulin-induced hypoglycemia), and secondary hypocortisolism (cortisol level, 105 nmol/L [170-550 nmol/L] and adrenocorticotropic hormone level, 6 pg/mL [5-65 pg/mL]). Serum prolactin level was normal (8.3 ng/mL [5-20 ng/mL]), and he was euthyroid on levothyroxine replacement. Magnetic resonance imaging revealed a partially empty sella. Sanger sequencing revealed a missense mutation (p.R218C/c.652C>T) in exon 4 of the TGFβ1 gene. The patient was treated with zoledronate, losartan, and oral prednisolone and continued on levothyroxine and testosterone replacement, which resulted in symptomatic improvement. DISCUSSION: The index case manifested severe CED requiring multimodality therapy. Later, he developed combined pituitary hormone deficiencies, which were managed with thyroid and gonadal hormone replacement with the continuation of glucocorticoids. The partial efficacy of bisphosphonates in CED has been reported in the literature. CONCLUSION: Skull base involvement in CED can lead to structural and functional hypopituitarism as a result of intracranial hypertension. ispartof: AACE Clin Case Rep vol:8 issue:2 pages:58-64 ispartof: location:United States status: Published online

Context Temozolomide (TMZ) is endorsed as the treatment of choice in aggressive or malignant pituitary adenomas. Objective Herein we describe a case of an aggressive prolactinoma that was resistant to TMZ. We performed a literature review of similar nonresponsive, aggressive prolactinomas. Methods A 40-year-old woman presented with a giant prolactinoma that required cabergoline, transsphenoidal surgery, and radiotherapy to achieve near-normal prolactin and apparently no residual tumor. A year later, she presented with multiple cranial nerve involvement due to a recurrent tumor extending to the infratemporal fossa. She underwent transfrontal surgery, second radiotherapy, and was started on TMZ. Despite 8 cycles of temozolomide (200 mg/m2, 5/28-day cycle), she had progressive disease and ultimately succumbed to the disease. PubMed/MEDLINE, Google Scholar, and prior review articles were searched for manuscripts about patients with aggressive prolactinomas who had been treated with TMZ. Data on demography, duration of therapy, and management outcomes were analyzed in those with progressive disease. Results We identified 94 cases of patients with aggressive/malignant prolactinomas in the literature who had received TMZ. Progressive disease despite TMZ was present in 36 cases (38%). There was a male preponderance (65%) among these and 40% had aggressive prolactinomas, whereas the rest had carcinomas. Patients received a median of 8 cycles (interquartile range, 3.5-11.5) of TMZ. O6-methylguanine-DNA-methyltransferase (MGMT) immunostaining was negative in 35%. Overall mortality at the time of publication was 40%, at a duration varying from 2 to 20 years from diagnosis. Conclusion TMZ resistance in aggressive/malignant prolactinomas is challenging. Progressive disease on optimal TMZ treatment entails the use of newer agents.

Gigantomastia refers to pathological breast enlargement usually occurring in the peripubertal or peripartum period. Idiopathic gigantomastia, however, is a rare entity with hypotheses citing local expression of hormones and growth factors in causing this disease, none of which have been systemically analysed. The purpose of this study was to delve deeper into the mechanistic pathways causing this condition. Herein, we describe three patients of idiopathic gigantomastia, all of whom had had normal puberty and uneventful pregnancies. Further, one of the patients had postmenopausal gigantomastia which is extremely rare, with only four cases described in the literature. Serum markers of autoimmunity, incriminated hormones and growth factors analysed, were normal in all the cases. Breast tissue specimens were subjected to histopathological examination and immunohistochemistry for ER, PR and Her-2-Neu. Quantitative immunofluorescence for aromatase, IGF2, EGFR, TGF-β, PDGFR-α, β, IGF1 and PTHrP was also performed. Of these, the tissue expression of aromatase, IGF2, EGFR, TGF-β, PDGFR-α and β were found to be upregulated, whereas IGF1 and PTHrP were comparable to normal breast. This observation that paracrine overexpression of these factors is responsible for the pathogenesis of apparently idiopathic gigantomastia may have therapeutic ramifications in the future for patients with this debilitating condition.

Context To diagnose and monitor GH-related disorders, serum IGF-I is a cornerstone, but Indian ethnicity based data, following consensus criteria for establishment of normative data are not available. Objectives To generate normative IGF-I data for chronological age (CA), Tanner stage and bone age (BA) [Greulich & Pyle (GP)] for both genders. Setting and Participants: We conducted a cross-sectional epidemiological study for Indian children (age 5-18 years) that included 2226 apparently normal subjects (1145 males; 1081 females). We used robust clinical exclusion criteria initially and later statistically we removed outliers separately for Age,Tanner Stage & Bone age using software SPSS 26. 0. Outcome Measures:: Serum IGF-I (ng/ml) using the Roche ECLIA & Immunodiagnostic Systems & Immunoassay System (IDS iSYS) were measured and normative data for 2.5th, 5th,10th, 25th, 50th (median), 75th, 90th, 95th and 97.5th centiles were generated. Results Age- and gender-specific serum IGF-I normative data generated from a uniquely large cohort reflected various patterns. With Roche assay, females (n=910) had IGF-I median peak at 13 years (356.85) [BA (n=804) at 14 years (401.5 ng/mL)] and & Tanner (n = 936) stage IV (368) while males (n=959) had median peak at 14 years (329.5) [BA (n=906) at 15 years (351 ng/mL)] & Tanner (n = 986) stage III (311. 0). With IDS iSYS assay, females had IGF-I median peak at Age (n=913) 13 years (397.5), Tanner (n=941) stage IV (418.5) and GP BA (n=843) 14 years (448.5) and males had median peak at Age (n=974) 14 years (376), Tanner (n=1003) stage III (367) and GP BA (n=909) 15-16 years (383). Females had earlier rise & peak and higher IGF-I values with both assays. In Tanner-specific data maximum difference noticed between stage II and III in both genders with both assays. On comparison of both assays, IGF-1 median peak was achieved at similar ages and Tanner stage but all the values are higher with IDS iSYS assay. When reviewed published literature on Caucasians, females had IGF-I median peak at 15 years (300.1) and Tanner stage III (382.8) and males had median peak at 15 years (318.3) and Tanner stage IV (439). The Indian & Caucasian IGF-1 normative data clearly demonstrates that every ethnicity has a unique pattern of growth. Conclusions The normative data on serum IGF-I are ethnicity-specific and it will improve the diagnostic utility of IGF-I in evaluation and management of growth disorders in Indian Children. Using both age- and Tanner stage-specific normative data simultaneously can improve diagnostic work-up. Presentation: Monday, June 13, 2022 12:30 p.m. - 2:30 p.m.

IntroductionEvidence on new-onset endocrine dysfunction and identifying whether the degree of this dysfunction is associated with the severity of disease in patients with COVID-19 is scarce.Patients and MethodsConsecutive patients enrolled at PGIMER Chandigarh were stratified on the basis of disease severity as group I (moderate-to-severe disease including oxygen saturation 94% and without comorbidities) (n=49). Hypothalamo-pituitary-adrenal, thyroid, gonadal axes, and lactotroph function were evaluated. Inflammatory and cell-injury markers were also analysed.ResultsPatients in group I had higher prevalence of hypocortisolism (38.5 vs 6.8%, p=0.012), lower ACTH (16.3 vs 32.1pg/ml, p=0.234) and DHEAS (86.29 vs 117.8µg/dl, p= 0.086) as compared to group II. Low T3 syndrome was a universal finding, irrespective of disease severity. Sick euthyroid syndrome (apart from low T3 syndrome) (80.9 vs 73.1%, p= 0.046) and atypical thyroiditis (low T3, high T4, low or normal TSH) (14.3 vs 2.4%, p= 0.046) were more frequent in group I than group II. Male hypogonadism was also more prevalent in group I (75.6% vs 20.6%, p=0.006) than group II, with higher prevalence of both secondary (56.8 vs 15.3%, p=0.006) and primary (18.8 vs 5.3%, p=0.006) hypogonadism. Hyperprolactinemia was observed in 42.4% of patients without significant difference between both groups.ConclusionCOVID-19 can involve multiple endocrine organs and axes, with a greater prevalence and degree of endocrine dysfunction in those with more severe disease.

Pheochromocytoma during pregnancy is a rare cause of secondary hypertension with lethal consequences to both mother and fetus. As patients are young, the possibility of syndromic associations like MEN-2, VHL, NF-1, etc., needs to be considered. Three primigravida were diagnosed before the 20th week of gestation when they presented with classical triad of pheochromocytoma. Diagnosis of pheochromocytoma was confirmed by 24 h urinary metanephrine/normetanephrine or epinephrine/norepinephrine levels. Non-contrast MRI abdomen could localize the tumor. One patient had medullary thyroid carcinoma with hyperparathyroidism, indicative of MEN-2A. Another patient had brain stem hemangioblastoma, pancreatic cysts and family history of spinal hemangioblastoma, so diagnosed to have Von Hippel-Lindau (VHL) syndrome. Whereas, the third patient had sporadic pheochromocytoma. Preoperatively, they required antihypertensive medications including prazosin and metoprolol. They underwent laparoscopic/open adrenalectomy between 19th and 21st week of gestation without complication. Histopathology in all the three patients revealed low-grade pheochromocytoma by pheochromocytoma of the adrenal gland scaled score. None required antihypertensive medications after surgery. All the three newborns were small for gestational age, while one neonate expired due to intra-cardiac rhabdomyoma. So, the timely evaluation and surgical intervention for pheochromocytoma avoid lethal consequences. Pregnancy leads to unmasking of pheochromocytoma as it is physiological stress. The syndromic association is more frequent as the population is younger. A poor fetal outcome like IUGR can be explained by endovascular changes in uterine vessel or due to the associated manifestations of MEN-2A, VHL syndromes. Family members should be screened for associated syndromic feature.

AimsInflammatory osteolysis is the sine-qua-non of active Charcot neuroarthropathy (CN). This study is aimed to provide mechanistic insights into pathogenesis of CN by exploring the role of methylprednisolone or zoledronate for remission of active CN. MethodsThirty-six patients with active CN (temperature difference >2°C from normal foot) were evaluated for time to remission. Patients were off-loaded with total contact cast and randomised to receive either methylprednisolone (1gm), zoledronate (5mg) or placebo (100ml normal saline) once monthly infusion for three consecutive months. Change in inflammatory cytokines (TNF-α, IL-1β), bone turnover markers (P1NPand CTX) and bone mineral content (BMC) was assessed. ResultsTime to remission of active CN was 19.4 ± 2.8 weeks with methylprednisolone compared to14.6 ± 4.4 and 13.5 ± 2.9 weeks (p0.05), while IL-1β reduced by 30% (p=0.02) with methylprednisolone, 21% with zoledronate and 16% with placebo (p>0.05). P1NP decreased by 5%, 24% and 19% with methylprednisolone, zoledronate and placebo, respectively. CTX decreased by 35% and 11% with zoledronate and placebo respectively but increased with methylprednisolone (18%) (p>0.05). Conclusion Effective suppression of either inflammation with methylprednisolone or osteoclastogenesis with zoledronate do not translate into earlier remission of active CN. The role of non-cytokine and non-inflammatory pathways for the activation of osteoclastogenesis in CN is purported.

Objective To analyze pregnancy course and outcomes in women treated for acromegaly and compare outcomes based on disease activity at the time of conception. Design Retrospective study. Patients Women with acromegaly diagnosed prior to or during pregnancy from 2010 to 2019, representing cases (14 pregnancies in 12 cases), were later stratified based on active (n = 5) or controlled disease (n = 9) at time of conception. Female acromegalic patients over the same period constituted the ‘acromegaly cohort’ (AC) (n = 75). Results All cases had macroadenomas with nadir GH of 15.06 ng/ml (IQR 9–30), IGF-I index of 3.04 (1.96–3.82), for which they had undergone pituitary surgery; except two patients diagnosed during pregnancy, who received pharmacotherapy followed by surgery 4 months postpartum. Adjuvant pharmacotherapy was required in 71.4% patients and radiotherapy in 35.7%. Pregnancy occurred at a median of 2 (0.8–5.1) years after surgery and 21.4% required assisted reproduction. All had term delivery with normal APGAR except one case with gestational hypertension, who delivered a preterm baby. None had congenital malformations. Despite higher baseline IGF-I, GH and tumor volume in those with pre-conceptional active acromegaly, materno-fetal outcomes were not different from those with controlled disease (p > 0.05). Similar or greater proportion of cases had normal GH and no residual tumor postpartum, even in those with pre-conceptional active acromegaly. Conclusion The current study showed conducive outcomes of gestation in women treated for acromegaly and no higher rates of pregnancy parameters or complications than non-acromegaly pregnancies in the same population. Active acromegaly does not seem to have an adverse bearing on outcomes.

Aims Inflammatory osteolysis is sine-qua-non of active Charcot neuroarthropathy (CN) causing decreased foot bone mineral density (BMD) and fractures. We aimed to explore the effect of anti-inflammatory or anti-resorptive agents for effect on foot bone mineral content (BMC) and consequent long-term outcomes of foot deformities, fractures and amputation. Methods Forty-three patients with active CN (temperature difference >2°C from normal foot) were evaluated. Patients were off-loaded with total contact cast and randomized to receive either methylprednisolone (1gm) (group A), zoledronate (5mg) (group B) or placebo (100ml normal saline) (group C) once monthly infusion for three consecutive months. Change in foot BMC was assessed at 6 months or at remission and followed subsequently up to 4 years for the incidence of new-onset fracture, deformities, or CN recurrence. Results Thirty-six participants (24 male, 12 female) were randomized (11 in group A, 12 group B, 13 group C). The mean age was 57.7± 9.9 years, duration of diabetes 12.3± 5.8 years and symptom duration 6.5± 2.8 weeks. BMC increased by 36% with zoledronate (p = 0.02) but reduced by 13% with methylprednisolone (p = 0.03) and 9% (p = 0.09) with placebo at remission. There were no incident foot fractures, however, two patients sustained ulcers, and 3 had new-onset or worsening deformities and none required amputation during 3.36 ± 0.89 years of follow-up. Conclusion Bisphosphonate for active CN is associated with an increase in foot bone mineral content as compared to decrease with steroids or total contact cast but long-term outcomes of foot deformities, ulceration and amputation are similar. Trial registration ClinicalTrials.gov: NCT03289338.

Objective Posterior pituitary tumours (PPTs) are rare neoplasms with the four recognised subtypes unified by thyroid transcription factor -1 (TTF-1) expression, according to the 2017 WHO classification. Though traditionally defined as low-grade neoplasms, a substantial proportion of them show recurrence/persistence following surgery. Methods We selected patients with PPTs in our cohort of 1760 patients operated for pituitary tumours over the past 10 years (2010–2019). The clinical, radiological, hormonal, histopathological profiles and long-term outcomes of the three cases identified (two pituicytomas and one spindle cell oncocytoma, SCO) were analysed. Following a literature review, data of all published cases with documented TTF-1 positive pituicytomas and SCOs were analysed to determine the predictors of recurrence/persistence in these tumours. Results Patients presented with compressive features or hypogonadism. Two had sellar-suprasellar masses. One had a purely suprasellar mass with a pre-operative radiological suspicion of pituicytoma. Two were operated by transsphenoidal surgery and one transcranially guided by neuronavigation. Histopathology confirmed spindle cells in a storiform arrangement and low Ki67 index. Immunohistochemistry showed positive TTF-1, S-100 expression and variable positivity for EMA, vimentin and GFAP. Re-evaluation showed recurrence/persistence in two patients. A literature review of recurrent/persistent pituicytoma (n = 17) and SCO (n = 9) cases revealed clinical clues (headache for pituicytomas, male gender for SCO), baseline tumour size (≥20.5 mm with sensitivity exceeding 80%) and longer follow-up duration as determinants of recurrence/persistence. Conclusion PPTs are rare sellar masses with quintessential TTF-1 positivity. Recurrent/persistent disease following surgery is determined by greater tumour size at baseline and duration of follow-up. This warrants intensive and long-term surveillance in these patients.

Eumycetomas are chronic suppurative granulomas caused by fungi characterised by invasive tumefactive lesions, sinuses and discharging grains. Herein, we describe a case of pedal eumycetoma due to Fusarium solani sensu stricto in a person with diabetes mellitus. A 45-year-old gentleman presented with an insidious onset swelling over his right foot with nodules and discharging grains. He had received itraconazole and anti-tuberculous therapy elsewhere, without response. Re-evaluation included a biopsy which confirmed eumycetoma and newly diagnosed diabetes. Surgical excision followed by histopathological, microbiological and multigene sequencing analyses [translation elongation factor, calmodulin and internal transcribed spacer region of rDNA] of the mould on culture were performed. Histopathology revealed septate fungal hyphae amidst a dense inflammatory infiltrate (Splendore–Hoeppli) reaction. Oral voriconazole was started and good glycemic control attained. Tissue growth sequences showed > 99% similarity with Fusarium solani sensu stricto. Antifungal susceptibility testing showed lowest MIC to voriconazole (0.5 mg/L). The patient showed excellent response to combined therapeutic modality with a near-complete resolution in size of lesion and obliteration of sinuses following 4 months of therapy and is planned for prolonged voriconazole therapy till complete radiological resolution. Diabetes predisposes to fungal infections of foot but eumycetomas are uncommon. Combined surgery and antifungals can improve morbidity and avoid amputations.

The COVID‐19 pandemic, caused by SARS‐CoV‐2, is an immense challenge for global healthcare. Diabetes mellitus, hypertension and obesity have been shown to portend poor prognosis in COVID‐19 despite no greater susceptibility to the infection (1). Chronic hypertension is commonly associated with vasculopathy which can predispose to severe infection. In patients with diabetes, severity is attributable to impaired innate, adaptive immunity, upregulation of ACE2 (entry receptor for SARS‐CoV2) by acute hyperglycemia and diabetic vasculopathy. The background of chronic low grade inflammation characterised by increased levels of IL‐6 and CRP in diabetes and obesity can also lead to an enhanced ‘cytokine storm’ in COVID‐19 (2). ACE2 expression on endothelial cells has been reported to cause viral mediated endothelitis and precipitate vascular dysfunction manifesting as acute respiratory distress syndrome as well as myocarditis, heart failure, arrhythmias, myocardial infarction and renal failure (3). In patients with pre‐existing comorbidities like hypertension, diabetes, obesity and chronic kidney disease, this new‐onset organ dysfunction can have deleterious additive effects.

Objective Vasculotoxic envenomation is an uncommon cause of hypopituitarism. Most described cases have varying extent of anterior pituitary dysfunction, but posterior pituitary involvement is extremely rare. Methods Clinical, biochemical, and radiologic evaluation of a young female who presented with secondary amenorrhea was performed. A brief literature review of envenomation-induced hypopituitarism is included. Results A 26-year-old female presented with secondary amenorrhea since the age of 20 years. She had normal stature. Her past medical history was significant for a vasculotoxic snakebite 12 years back requiring hemodialysis, but no hormonal testing was done at that time. Current evaluation showed anterior hypopituitarism. An insulin-induced hypoglycemia test confirmed deficiencies of cortisol and growth hormone axes (peak values 348 nmol/L and 0.03 ng/mL). There was no diabetes insipidus. Magnetic resonance imaging revealed a hypoplastic anterior pituitary with an ectopic posterior pituitary. In view of normal stature and secondary amenorrhea, a diagnosis of envenomation-induced hypopituitarism with ectopic posterior pituitary (EPP) was made. A brief literature review of envenomation-induced hypopituitarism showed both acute and delayed presentation, male predominance, and variable lag period (weeks to years). Nearly half of all patients were asymptomatic. The most common axis involved in acute presentation was the cortisol axis, whereas the thyroid and gonadotroph axes were commonly involved in delayed hypopituitarism. Conclusion Vasculotoxic envenomation is a rare cause of acquired hypopituitarism. EPP in the index case was probably due to the "axonal dieback" phenomenon and subsequent regeneration of the axons at a more caudal site. This case, being the first instance of acquired EPP following envenomation, expands the spectrum of envenomation-induced hypopituitarism.

Triple A (Allgrove) syndrome is a rare autosomal recessive disorder characterized by cardinal features of primary adrenal insufficiency (AI) due to adrenocorticotropic hormone (ACTH) resistance, achalasia, and alacrima. It is frequently associated with neurological manifestations such as autonomic dysfunction, cognitive dysfunction, cranial nerve, or motor involvement. Amyotrophy/motor neuron disease is a rare association. We herein report a 19-year-old boy diagnosed with triple A syndrome (TAS), with the classic triad of ACTH-resistant adrenal insufficiency, achalasia, and alacrima. Additionally, he had distal spinal muscle amyotrophy. Alacrima was the earliest feature evident in early childhood, followed by achalasia at 12 years of age. He was diagnosed with AI at the age of 19 years, with involvement of the mineralocorticoid axis. Further evaluation showed a neurogenic pattern on electromyography, consistent with a diagnosis of motor neuron disease. A nerve conduction study revealed no significant neuropathy. Genetic analysis confirmed a pathogenic homozygous mutation in the AAAS gene c.43C>A, p.Gln15Lys. He improved with glucocorticoid and mineralocorticoid supplements for AI, and nifedipine for achalasia and artificial tears. He is planned for esophagomyotomy. In any young patient with AI not due to congenital adrenal hyperplasia, Allgrove syndrome should be ruled out. Though mineralocorticoid sparing pattern is classical, it can rarely be involved, as seen in the index case. Various components of the syndrome, as well as amyotrophy and other neurologic features, may present in a metachronous fashion. Hence, a high index of clinical suspicion can aid in early diagnosis and management.
