Pharmacokinetic properties of cortisone acetate (CA) and hydrocortisone (HC) differ because CA needs to be converted into cortisol to become active.

This work analyzed the metabolic consequences of switching CA to an equivalent daily dose of HC in patients with secondary adrenal insufficiency (SAI).

This was a post hoc analysis from a prospective study including individuals with hypopituitarism receiving growth hormone replacement. Data were collected before and after a switch from CA to an equivalent dose of HC (switch group). Two control groups were included patients continuing CA replacement (CA control group) and adrenal-sufficient hypopituitary patients (AS control group).

The analysis included 229 patients 105, 31, and 93 in the switch, CA control, and AS control groups, respectively. After the change from CA to HC, increases in mean body weight (1.2 kg;
 < .05), waist circumference (2.9 cm;
 < .001), body fat measured by dual-energy x-ray absorptiometry (1.3 kg;
 < .001), and glycated hemoglobin (0.3%;
 < .05) were recorded in the switch group. The increase in mean waist circumference was greater than in the AS control group (0.9 cm;
 < .05). Mean body fat increased in the switch group but not in the CA control group (-0.7 kg;
 < .05).

A switch from CA to an equivalent dose of HC was associated with a worsened metabolic profile, suggesting that HC has a more powerful metabolic action than CA based on the assumption that 20 mg HC equals 25 mg CA.

There are multiple etiologies to consider, and a comprehensive evaluation is often pursued. Sometimes, however, despite a thorough workup, the diagnosis remains unclear. Here, we report an unusual cause of secondary amenorrhea in a 15-year-old girl. Our patient presented with secondary amenorrhea after a 4-year history of regular menstrual cycles. Her evaluation was notable for very low FSH and low estradiol but normal LH; pregnancy, adrenal, thyroid, prolactin studies, and brain magnetic resonance imaging scan did not reveal a cause of her amenorrhea. Her transabdominal ultrasound showed an enlarged right ovary, initially suggestive of a hemorrhagic cyst. Inhibin A and B were measured because of the persistently low FSH; these were found to be very elevated, concerning for an inhibin-producing tumor. The patient had surgical removal of her right ovary; pathology revealed a juvenile granulosa-cell tumor. Postoperatively, the patient had normalization of serum inhibin A and B and resumption of normal menstrual cycles. This report illustrates that careful consideration of laboratory findings and other studies is essential for correctly identifying the underlying cause of secondary amenorrhea, particularly when the results are not consistent with common causes of this condition.Estrogen (17β-estradiol or E2) is a crucial regulator of the synthesis and secretion of pituitary reproductive hormones luteinizing hormone, follicle-stimulating hormone, and prolactin. In this review, we summarize the role of estrogen receptors in nonfunctioning pituitary neuroendocrine tumors (NF-Pitnets), focusing on immunoexpression and gonadotroph cell proliferation and apoptosis. Gonadotroph tumors are the most common subtype of NF-Pitnets. Two major estrogen receptor (ER) isoforms expressed in the pituitary are estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ). Overall, estrogen actions are mostly exerted through the ERα isoform on the pituitary. The G protein-coupled estrogen receptor (GPER) located at the plasma membrane may contribute to nongenomic effects of estrogen. Nuclear immunoreactivity for ERα and ERβ was highest among gonadotroph and null cell tumors. Silent corticotroph tumors are the least immunoreactive for both receptors. A significantly elevated ERα expression was observed in macroadenomas compared with microadenomas. ERα and ERβ may act in opposite directions to regulate the Slug-E-cadherin pathway and to affect invasiveness of NF-Pitnets. In the cellular pathway, ERs regulate estrogen-induced proliferation and differentiation and impact several signaling pathways including the MAPK and PI3K/Akt pathway. Estrogen was the first-discovered inducer of pituitary tumor transforming gene 1 that was abundantly expressed in NF-Pitnets. ERα can be a potential biomarker for predicting tumor size and invasiveness as well as therapeutic target for NF-Pitnets. Selective estrogen receptor modulators or antiestrogen may represent as an alternative choice for the treatment of NF-Pitnets.[This corrects the article DOI 10.1210/jendso/bvaa037.].
Abdominal surgeries are performed for the treatment and diagnosis of many diseases. selleck chemical Smokers undergoing abdominal surgery, are high risk population, having underlying pathological changes in lung parenchyma due to inflammatory effect of smoking. Site of incision and history of smoking may significantly affect pulmonary function such as FVC and FEV1. Respiratory muscle training pre-operatively has shown significant improvement of pulmonary function compare to only conventional therapy and has led to reduction of PPCs, length of hospital stay and cost. This study aims to find effectiveness of IMT in chronic smokers undergoing abdominal surgery and its significance in reduction of PPC and in pulmonary function and functional capacity as compared to non-smokers.

This study protocol is observational cohort study comparing smoker and non-smoker participants undergoing abdominal surgery. The participants will be assessed for pulmonary function test and functional capacity (6MWD); pre-operatively and post-operatively day 1 till the day of discharge. Both the groups will receive IMT and conventional chest Physiotherapy from POD1 and increment of IMT will be done by assessing MIP each day.
