A detailed appraisal of renal manifestations in primary hyperparathyroidism from Indian PHPT registry: Before and after curative parathyroidectomy.

BACKGROUND: Primary hyperparathyroidism (PHPT) is a systemic disorder characterized by hypercalcaemia and inappropriately elevated parathyroid hormone (PTH). Renal manifestations are one of the main presenting features both in symptomatic and asymptomatic PHPT patients. OBJECTIVES: We aimed to compare demographic, clinical and biochemical parameters of PHPT patients with and without renal manifestations and also analysed the influence of curative parathyroidectomy on renal functions. METHODS: We retrospectively analysed the data of PHPT patients from the last 25 years (1995- March 2019) and compared the demographic and clinical presentation and biochemical measurements between patients with and without renal manifestations and evaluated the changes in renal functions after 1 year of curative parathyroidectomy. RESULTS: Of the total 544 PHPT patients, 299 (55%) including 91 out of 141 (65%) males had renal manifestations. Among renal manifestations, nephrolithiasis and nephrocalcinosis were found in 41.7% and 27.6% PHPT patients, respectively. PHPT patients with renal manifestations had significantly higher creatinine (109.7 vs 79.6 µmol/L; P < .0001) and lower eGFR level (78.8 vs 93.9 mL/min/1.73 m2 ; P < .0001) compared to patients without renal manifestations. Parathyroidectomy resolved the clinical symptoms with biochemical cure in the patients from both the groups. Patients with renal manifestations showed improvement in creatinine and eGFR levels after 1 year of curative parathyroidectomy; however, patients without renal manifestations showed no change in creatinine and eGFR levels. CONCLUSION: Young age and male gender are predictors of renal manifestations in PHPT. Curative parathyroidectomy improves renal functions in PHPT patients with renal manifestations compared to PHPT patients without renal manifestation.

Progressive rise in the prevalence of asymptomatic primary hyperparathyroidism in India: Data from PHPT registry.

INTRODUCTION: Primary hyperparathyroidism (PHPT), a third common endocrine disorder, varies from asymptomatic disease, mostly seen in the West where routine biochemical screening is practiced, to the classical symptomatic disease mostly seen in the Eastern countries. We aimed to compare the demographic, clinical, biochemical measurements in patients with asymptomatic and symptomatic PHPT from the Indian PHPT registry. MATERIAL AND METHODS: Data of PHPT patients from the last 25 years (1995-2019) were analyzed for demographic, clinical presentation and biochemical measurements, and compared these characteristics between asymptomatic and symptomatic PHPT patients. RESULTS: Of the 554 patients, 54 (10%) patients had asymptomatic PHPT. There was a sharp rise in the proportion of asymptomatic PHPT patients of 3% in the first decade to 13% in the second decade of the century (p = 0.003). Patients with asymptomatic PHPT were significantly older (50 vs. 42 years; p < 0.0001) and had higher mean body mass index (27.8 vs. 23.5 kg/m2; p < 0.0001) compared to the symptomatic PHPT group. In addition, asymptomatic PHPT patients had significantly lower median plasma iPTH (180 vs. 370 pg/mL; p < 0.0001), serum alkaline phosphatase (119 vs. 172 IU/L; p < 0.0001), and parathyroid adenoma weight (1.0 vs. 2.62 g; p = 0.006) compared to the symptomatic PHPT group. CONCLUSION: Although symptomatic PHPT is still most prevalent (> 90%) in India with higher indices of the disease and tumor weights, there is a progressive rise in the prevalence of asymptomatic PHPT patients in the last decade. Improvements in calcium and vitamin D nutrition might account for this change as in the Western series.

Differences in Primary Hyperparathyroidism Between Pre- and Postmenopausal Women in India.

OBJECTIVE: Primary hyperparathyroidism (PHPT) is a common endocrine disorder in women which becomes more prevalent after menopause. In this study, we compared the demographic, clinical, and biochemical variables between premenopausal (pre-M) and postmenopausal (post-M) women with PHPT. METHODS: A retrospective analysis (from 2005 to 2019) of enrolled women PHPT patients from an online Indian PHPT registry. RESULTS: Of the women with PHPT, 232 and 122 were pre-M and post-M, respectively. The number of post-M PHPT cases registered had a 3.3-fold increase in 2015-2019 from 2005-2009 compared with only a 2.5-fold increase in pre-M cases in the same duration. The majority were symptomatic (90%), although pre-M had a higher proportion of symptomatic than post-M (92% vs 85%; P = .04). Pre-M women showed more prevalence of osteitis fibrosa cystica than post-M women (28% vs 13%; P = .03), although hypertension and gallstone disease were seen more frequently in post-M PHPT women. Pre-M women had a significantly higher median PTH (403 vs 246 pg/mL; P = .02) and median alkaline phosphatase (202 vs 145 pg/mL; P = .02) than post-M women, and vitamin D deficiency was more common in pre-M women (58% vs 45%; P = .03). Gland localization, tumor weight, and disease cure rates did not differ according to menopausal status. CONCLUSION: PHPT was more prevalent in pre-M women, although the number of post-M cases had significantly increased in the last 10 years. Pre-M women had generally more severe clinical and biochemical variables than post-M PHPT women.

Autonomous growth hormone secretion due to McCune Albright syndrome in paediatric age group: an ominous triad.

PURPOSE: The current study aimed to report cases of McCune Albright syndrome (MAS) with growth hormone (GH) hyper secretion along with a systematic review of literature to elucidate challenges and intricacies in its diagnosis and management. METHODS: It was a single centre study carried out in individuals with MAS and autonomous GH secretion (AGHS). In addition, a systematic search of literature across three databases (PubMed, Scopus and EMBASE) was performed from inception until May 31, 2021 to identify cases of MAS with AGHS in the pediatric age group (<18 years). RESULTS: Three cases from authors centre and 42 cases identified from systematic literature review were analysed. Precocious puberty was the most common presenting endocrinopathy seen in 56.8% (25/44) cases, followed by hyperthyroidism (10/45), hypophosphatemia (4/45), and hypercortisolism (2/45). Cranio-facial fibrous dysplasia (CFFD) was seen in all while polyostotic fibrous dysplasia and Café au lait macule was seen in 40/45 (88.9%) and 35/45 (77.8%), respectively. Pituitary adenoma (58.3% microadenoma) was localized in 53.3% (24/45) cases on pituitary imaging. Biochemical and clinical remission of AGHS was achieved in 61.5% (24/45) cases with medical therapy. CONCLUSION: Diagnosing AGHS in MAS is challenging because of concomitant presence of CFFD, non-GH endocrinopathies associated height spurt and elevated serum IGF-1. GH-GTT should be performed in presence of elevated growth velocity and serum IGF-1 (>1 X ULN) despite adequate control of non-GH endocrinopathies. Medical management can lead to disease control in substantial number of cases and often entails use of multiple agents.

Pheochromocytoma in Pregnancy: A Syndromic Association.

Introduction: 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. Methodology: Three primigravida were diagnosed before the 20th week of gestation when they presented with classical triad of pheochromocytoma. Results: 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. Conclusions: 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.

Abdominal obesity and incident cardio-metabolic disorders in Asian-Indians: A 10-years prospective cohort study.

BACKGROUND AND AIMS: To estimate the strength of association between abdominal obesity and incident cardio-metabolic diseases. METHODS: A subset of Chandigarh Urban Diabetes study cohort (n = 543) was followed after a mean of 10.7 years for development of diabetes, prediabetes, dysglycaemia (either prediabetes or diabetes), hypertension and atherosclerotic cardiovascular disease (ASCVD). Diabetes and prediabetes were defined as per American Diabetes Association consulting group criteria, hypertension as blood pressure of ≥140/90 mmHg and ASCVD after review of medical records. Abdominal obesity was defined as waist circumference of ≥80 cm and ≥90 cm in females and males, respectively. RESULTS: As compared to non-obese (n = 209), abdominally obese individuals (n = 334) had a higher risk of diabetes [RR:1.82(1.28-2.57)], prediabetes [RR:1.40(1.05-1.85)], dysglycaemia [ RR:1.38(1.07-1.78)], hypertension [RR: 1.84(1.30-2.59)] and ASCVD [RR:2.12(1.02-4.4)]. The optimal cut-off of waist circumference for detecting incident diabetes, hypertension and ASCVD in females was 88 cm, 85 cm and 91 cm, respectively; while in males it was 90 cm, 87 cm and 94 cm, respectively. CONCLUSION: In Asian-Indians, abdominal obesity as defined by waist circumference of ≥90 cm and ≥80 cm in males and females, respectively is associated with a twofold higher risk of diabetes, hypertension and ASCVD. In addition, the current-cut-offs of waist circumference to define abdominal obesity need reconsideration to optimally identify individuals at a higher risk of cardio-metabolic diseases. However, a high attrition rate represents a major limitation.

Utility of high fat and low carbohydrate diet in suppressing myocardial FDG uptake.

INTRODUCTION: Fluoro-deoxy-glucose (FDG) can be used to visualize inflammation in atherosclerotic plaques in coronary arteries, if myocardial FDG uptake is adequately suppressed. Prolonged fasting for suppressing myocardial FDG uptake is inconsistent. We evaluated the feasibility to consistently suppress myocardial FDG uptake with a low carbohydrate high fat protein permitted (LCHFPP) diet. MATERIALS AND METHODS: This was a prospective study. 50 patients were included in fasting group (>12 hours fasting) and 60 patients were included into LCHFPP diet. Fasting group had no special dietary preparation. Patients in LCHFPP diet group were asked to consume LCHFPP diet the night before and 4 hours prior to the study. Visual analysis of myocardial FDG uptake was done on maximum intensity projection image. Using CT images for localization, the ability to delineate possible FDG uptake in the left coronary artery was assessed in the corresponding PET image and the studies were classified as "interpretable" or "Not interpretable". RESULTS: 60 patients (mean age 47 years) from LCHFPP diet group and 50 patients (mean age 49.9 years) from fasting group were included. None of the patients were known diabetics. The mean blood glucose level was 96 mg/dL. Forty-eight patients had consumed LCHFPP diet as per protocol. Twelve had consumed LCHFPP diet only on the night before the study (non-compliant). The average duration of fasting in compliant patients was 5.9 ± 0.9 hours in the diet group and 14.6 hours in fasting group. In LCHFPP diet group, the myocardial FDG uptake was classified as complete suppression in 31; minimal uptake in 15; moderate inhomogenous uptake in 8 and homogenous intense uptake in 6 patients. Fifty-four of the 60 patients had interpretable study. When non-compliant patients were excluded, 84% of the patients had significant FDG uptake suppression and 94% of the studies were classified as interpretable. In the fasting group, complete myocardial suppression of FDG uptake was noticed in 16; minimal in 8; moderate inhomogenous in 15; and homogenous intense in 11 patients. 27 patients (54%) had interpretable study. CONCLUSION: Consistent and significant myocardial FDG uptake suppression is possible in most patients using LCHFPP diet. The LCHFPP diet, if taken as per protocol, leads to consistent myocardial FDG uptake suppression to allow for adequate evaluation of the left coronary artery inflammation in nearly all the patients. LCHFPP diet is also significantly more efficacious than prolonged (>12 hours) fasting protocol in suppressing myocardial FDG uptake.

Triple A (Allgrove) syndrome due to AAAS gene mutation with a rare association of amyotrophy.

INTRODUCTION: 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. CASE PRESENTATION: 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. CONCLUSION: 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.

Spectrum of Endocrine Dysfunction and Association With Disease Severity in Patients With COVID-19: Insights From a Cross-Sectional, Observational Study.

Introduction: Evidence 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 Methods: Consecutive patients enrolled at PGIMER Chandigarh were stratified on the basis of disease severity as group I (moderate-to-severe disease including oxygen saturation <94% on room air or those with comorbidities) (n= 35) and group II (mild disease, with 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. Results: Patients 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. Conclusion: COVID-19 can involve multiple endocrine organs and axes, with a greater prevalence and degree of endocrine dysfunction in those with more severe disease.

Primary Hyperparathyroidism Presenting as Posterior Reversible Encephalopathy Syndrome: A Report of Two Cases

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity characterized by subcortical vasogenic edema presenting with acute neurological symptoms. Common precipitating causes include renal failure, pre-eclampsia/eclampsia, post-organ transplant, and cytotoxic drugs. Hypercalcemia is a rare cause of PRES; most cases occur in the setting of severe hypercalcemia secondary to malignancy or iatrogenic vitamin D/calcium overdose. Primary hyperparathyroidism (PHPT), as a cause of PRES, is an oddity. We report two cases of adolescent PHPT presenting with generalized tonic-clonic seizures and altered sensorium. On evaluation, both had hypertension, severe hypercalcemia (serum calcium 14.1 mg/dL and 14.5 mg/dL, respectively) and elevated parathyroid hormone levels. Magnetic resonance imaging (MRI) revealed T2/fluid-attenuated inversion recovery hyperintensities located predominantly in the parieto-occipital regions, suggestive of PRES. Identification and excision of parathyroid adenoma led to the restoration of normocalcemia. Neurological symptoms and MRI changes improved subsequently. An extensive literature search revealed only four cases of PHPTassociated PRES; none of them being in the pediatric/adolescent age group. The predominant clinical manifestations were seizures and altered sensorium. All had severe hypercalcemia; three had hypertension at presentation, while one was normotensive. Parathyroid adenomectomy led to normalization of serum calcium and resolution of neurological symptoms and radiological changes. Thus, severe hypercalcemia, although rare in PHPT, can lead to hypercalcemic crisis precipitating acute hypertension that can result in cerebral endothelial dysfunction with the breakdown of the blood-brain barrier, culminating in PRES. We therefore recommend that serum calcium levels should be checked in all patients with PRES and that PHPT be regarded as a differential diagnosis in those with underlying hypercalcemia.

Advanced case of PKDL due to delayed treatment: A rare case report.

Post-kala-azar dermal leishmaniasis (PKDL) is clinical outcome of visceral leishmaniasis (VL) and is thought to be the potential reservoir of parasite. Miltefosine (MF) is the only oral drug existing for treatment of post-kala-azar dermal leishmaniasis (PKDL). Increased miltefosine tolerance in clinical isolates of Leishmania donovani has been reported and is one of the major concerns in the treatment of PKDL. Here, we report a highly ulcerated PKDL case that was successfully cured after miltefosine treatment.

False Positivity of rK39 Test in Five Chronic Myeloid Leukemia Cases from Bihar, India: A Possible Challenge to Leishmaniasis Diagnosis.

A rapid and noninvasive rK39 rapid diagnostic test (RDT) is the best and most reliable tool for visceral leishmaniasis (VL) screening in the field. However, splenic and bone marrow aspiration remain two gold standard methods for microscopic identification of Leishmania donovani (LD) bodies and confirmatory diagnosis of VL. Five patients with signs and symptoms of fever, loss of appetite, loss of weight, hepatomegaly, and massive splenomegaly were found to be false positive with the rK39 RDT. These patients were suspected to have chronic myeloid leukemia (CML) because their blood pictures showed a total white blood cell count of > 100,000/mm3 and abnormal cells such as stab, segmented promyelocytes, myelocytes, metamyelocytes, and blast cells. Splenic aspirate and bone marrow were negative for Leishmania donovani bodies. The bone marrow showed myeloid series of cells, that is, myelocytes, metamyelocytes, stab and segmented cells, blast cells, and markedly increased myeloid:erythroid ratio. Later, the CML diagnosis was confirmed in all cases by breakpoint cluster region-tyrosine protein kinase (BCR-ABL) gene positive test results. In this study, the rK39 RDT's false positivity was observed in CML cases. It could have important implications for the differential diagnosis of VL with CML. The rK39 positive test result in CML cases was a serendipitous occurrence; this should be validated further to determine the utility of the rK39 test in the differential diagnosis of VL with CML.

Noninvasive Sweat-Based Diagnosis of Visceral Leishmaniasis and Post Kala-Azar Dermal Leishmaniasis.

The diagnosis of visceral leishmaniasis (VL) is one of the foremost barriers in the control of this disease, as demonstration of the parasite by splenic/bone marrow aspiration is relatively difficult and requires expertise and laboratory support. The aim of the present study was to find a noninvasive diagnostic approach using the existing recombinant kinesine-39 (rK-39) immunochromatographic nitrocellulose strips test (ICT) with a human sweat specimen for the diagnosis of VL. The investigation was carried out on specimens (blood, sweat, and urine) collected from 58 confirmed VL, 50 confirmed post kala-azar dermal leishmaniasis (PKDL), 36 healthy control, and 35 patients from other diseases. The data obtained from this study reveal that 96.6% clinically confirmed active VL participants were found to be positive when tested against a sweat specimen. Interestingly, the scenario was similar when tested against a blood specimen (96.6% positive by rK-39). Moreover, a test of both sweats and blood specimens from 50 PKDL participants resulted in 100% positivity, whereas no healthy control participants were found to be rK-39 positive. The sensitivity of the rK-39 ICT in sweat specimen was 94.7%, whereas the specificity was 100% in healthy controls from endemic, nonendemic, and other infectious diseases, respectively. No difference was observed in sweat specimen of VL and PKDL cases which signifies its reliability. However, further evaluation of this method on a larger scale could enhance the reliability of the proposed model so that it could be used efficiently in VL management and eradication.

IndEcho study: cohort study investigating birth size, childhood growth and young adult cardiovascular risk factors as predictors of midlife myocardial structure and function in South Asians.

INTRODUCTION: South Asians have high rates of cardiovascular disease (CVD) and its risk factors (hypertension, diabetes, dyslipidaemia and central obesity). Left ventricular (LV) hypertrophy and dysfunction are features of these disorders and important predictors of CVD mortality. Lower birth and infant weight and greater childhood weight gain are associated with increased adult CVD mortality, but there are few data on their relationship to LV function. The IndEcho study will examine associations of birth size, growth during infancy, childhood and adolescence and CVD risk factors in young adulthood with midlife cardiac structure and function in South Asian Indians. METHODS AND ANALYSIS: We propose to study approximately 3000 men and women aged 43-50 years from two birth cohorts established in 1969-1973: the New Delhi Birth Cohort (n=1508) and Vellore Birth Cohort (n=2156). They had serial measurements of weight and height from birth to early adulthood. CVD risk markers (body composition, blood pressure, glucose tolerance and lipids) and lifestyle characteristics (tobacco and alcohol consumption, physical activity, socioeconomic status) were assessed at age ~30 years. Clinical measurements in IndEcho will include anthropometry, blood pressure, biochemistry (glucose, fasting insulin and lipids, urinary albumin/creatinine ratio) and body composition by dual energy X-ray absorptiometry and bioelectrical impedance. Outcomes are LV mass and indices of LV systolic and diastolic function assessed by two-dimensional and Doppler echocardiography, carotid intimal-media thickness and ECG indicators of ischaemia. Regression and conditional growth models, adjusted for potential confounders, will be used to study associations of childhood and young adult exposures with these cardiovascular outcomes. ETHICS AND DISSEMINATION: The study has been approved by the Health Ministry Steering Committee, Government of India and institutional ethics committees of participating centres in India and the University of Southampton, UK. Results will be disseminated through scientific meetings and peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN13432279; Pre-results.

Evaluation of MR Spectroscopy and Diffusion-Weighted MRI in Postmenopausal Bone Strength.

AIM: To prospectively investigate the role of MR spectroscopy (MRS) and diffusion-weighted magnetic resonance imaging (DWI) in assessing vertebral marrow changes in postmenopausal women. MATERIALS AND METHODS: Fifty postmenopausal women, who underwent dual-energy x-ray absorptiometry of the spine, were divided into three bone density groups (normal, osteopenia, and osteoporosis) based on T-score. Both MRS and DWI of the L3 vertebral body were performed to calculate the marrow fat content and apparent diffusion coefficient (ADC). The results were compared between three groups and correlated with BMD. RESULTS: Vertebral marrow fat content was significantly increased in the osteoporotic group when compared with that of the osteopenic group and the normal bone density group. ADC values in the osteoporotic, osteopenic, and normal bone density groups were 338, 408 and 464, respectively, with statistically significant differences (P < 0.001). A statistically significant positive correlation between T-scores and ADC existed (r=0.694, p value <0.001). The vertebral marrow fat content was negatively correlated to the bone density (r=-0.455, p< 0.001) and to marrow ADC (r= -0.302, p < 0.05). CONCLUSION: The postmenopausal women with osteoporosis exhibited a corresponding increase in vertebral marrow fat content as the bone density decreased. Marrow fat content and ADC were related to the bone density. MRS and DWI are helpful in evaluating the bone marrow changes in postmenopausal women.
