Endocrine Dysfunction Criteria in Critically Ill Children: The PODIUM Consensus Conference

CONTEXT Endocrine dysfunction is common in critically ill children and is manifested by abnormalities in glucose, thyroid hormone, and cortisol metabolism. OBJECTIVE To develop consensus criteria for endocrine dysfunction in critically ill children by assessing the association of various biomarkers with clinical and functional outcomes. DATA SOURCES PubMed and Embase were searched from January 1992 to January 2020. STUDY SELECTION We included studies in which researchers evaluated critically ill children with abnormalities in glucose homeostasis, thyroid function and adrenal function, performance characteristics of assessment and/or scoring tools to screen for endocrine dysfunction, and outcomes related to mortality, organ-specific status, and patient-centered outcomes. Studies of adults, premature infants or animals, reviews and/or commentaries, case series with sample size ≤10, and non–English-language studies were excluded. DATA EXTRACTION Data extraction and risk-of-bias assessment for each eligible study were performed by 2 independent reviewers. RESULTS The systematic review supports the following criteria for abnormal glucose homeostasis (blood glucose [BG] concentrations >150 mg/dL [>8.3 mmol/L] and BG concentrations <50 mg/dL [<2.8 mmol/L]), abnormal thyroid function (serum total thyroxine [T4] <4.2 μg/dL [<54 nmol/L]), and abnormal adrenal function (peak serum cortisol concentration <18 μg/dL [500 nmol/L]) and/or an increment in serum cortisol concentration of <9 μg/dL (250 nmol/L) after adrenocorticotropic hormone stimulation. LIMITATIONS These included variable sampling for BG measurements, limited reporting of free T4 levels, and inconsistent interpretation of adrenal axis testing. CONCLUSIONS We present consensus criteria for endocrine dysfunction in critically ill children that include specific measures of BG, T4, and adrenal axis testing.

Recurrent Implantation Failure—Is It the Egg or the Chicken?

Recurrent implantation failure (RIF) is an undefined, quite often, clinical phenomenon that can result from the repeated failure of embryo transfers to obtain a viable pregnancy. Careful clinical evaluation prior to assisted reproduction can uncover various treatable causes, including endocrine dysfunction, fibroid(s), polyp(s), adhesions, uterine malformations. Despite the fact that it is often encountered and has a critical role in Assisted Reproductive Technique (ART) and human reproduction, RIF’s do not yet have an agreed-on definition, and its etiologic factors have not been entirely determined. ART is a complex treatment with a variable percentage of success among patients and care providers. ART depends on several factors that are not always known and probably not always the same. When confronted with repeated ART failure, medical care providers should try to determine whether the cause is an embryo or endometrium related. One of the most common causes of pregnancy failure is aneuploidy. Therefore, it is likely that this represents a common cause of RIF. Other RIF potential causes include immune and endometrial factors; however, with a very poorly defined role. Recent data indicate that the possible endometrial causes of RIF are very rare, thereby throwing into doubt all endometrial receptivity assays. All recent reports indicate that the true origin of RIF is probably due to the “egg”.

Endocrine Disorder in Patients With Craniopharyngioma

Craniopharyngioma is an intracranial congenital epithelial tumor growing along the pathway of the embryonic craniopharyngeal tube. The main clinical symptoms of patients with craniopharyngioma include high intracranial pressure, visual field defect, endocrine dysfunction, and hypothalamic dysfunction. At present, the preferred treatment remains the surgical treatment, but the recovery of endocrine and hypothalamic function following surgery is limited. In addition, endocrine disorders often emerge following surgery, which seriously reduces the quality of life of patients after operation. So far, research on craniopharyngioma focuses on ways to ameliorate endocrine dysfunction. This article reviews the latest research progress on pathogenesis, manifestation, significance, and treatment of endocrine disorders in patients with craniopharyngioma.

Nivolumab-Induced Exocrine Pancreatic Insufficiency

Immunotherapy is increasingly gaining applicability for several malignancies. While the survival of several malignancies has dramatically improved, immune-related adverse events (irAEs) can occur and can cause severe damage to patients. Side effects such as colitis are well known nowadays; however, with increased use of immunotherapy, less common side effects should also be addressed. In this article, 2 patients that received nivolumab developed exocrine dysfunction of the pancreas. Endocrine dysfunction has been well known, but exocrine dysfunction is less often described. It is important to be aware of this side effect because it is possibly underdiagnosed. Symptoms often mimic symptoms of malignancy, chemotherapy side effects, or immune-related colitis. Although the exact mechanism is yet to be elaborated, dormant CD8+ T cells are likely to be involved. No known therapy is yet been proven to be effective. More knowledge and research about irAEs will lead to possible therapies that will be effective. Currently, high-dose prednisone is recommended based on expert opinion.

Prevention of pathological fracture in fibrous dysplasia of proximal femur in a 24-year-old female a rare presentation - a case report

<p class="abstract">Fibrous dysplasia (FD) was historically mentioned in the medical literature in 1938 by Dr. Lichtenstein and in 1942 by Dr. Lichtenstein and Jaffe. The term Jaffe-Lichtenstein syndrome is sometimes used synonymously with monostotic FD or to denote cases of polyostotic FD with café au lait spots, but no endocrine dysfunction. Our case is a 24-year-old female, housewife presented to our hospital with a complaints of right hip pain and backache with difficulty in walking of 6 months duration. She had dull aching pain which increased in intensity with the course of time, there was no radiation, but was aggravated by movements. She was managed with dynamic hip screw along with curettage of the lesion and bone graft, after 9 months of follow up, she had no pain over her hip and there was calcification over the previous lesion, our patient had a very favourable outcome.</p>

Lateralized phenotypic differences in females in the intrahippocampal kainic acid mouse model of temporal lobe epilepsy

Clinical evidence indicates that patients with temporal lobe epilepsy (TLE) often show differential outcomes of comorbid conditions dependent on the lateralization of the seizure focus. However, whether a left or right seizure focus produces differential effects on comorbid outcomes has not been investigated in a rodent model of chronic recurrent seizures. Here, we used the intrahippocampal kainic acid (IHKA) mouse model of TLE to determine whether targeting of left or right dorsal hippocampus for injection produces different outcomes in hippocampal sclerosis, body weight gain, and multiple measures of reproductive endocrine dysfunction in female mice. At one, two, and four months after injection, in vivo measurements of estrous cycles and weight were followed by ex vivo examination of hippocampal sclerosis, circulating ovarian hormone and corticosterone levels, ovarian morphology, and pituitary gene expression. IHKA mice with right-targeted injection (IHKA-R) showed greater granule cell dispersion and pituitary Fshb expression compared to mice with left-targeted injection (IHKA-L). By contrast, pituitary expression of Lhb and Gnrhr were higher in IHKA-L mice compared to IHKA-R, but these values were not different from respective saline-injected controls. IHKA-L mice also showed an increased rate of weight gain compared to IHKA-R mice. Disruptions to estrous cyclicity, however, were similar in both IHKA-L and IHKA-R mice. These findings indicate that although major reproductive endocrine dysfunction phenotypes present similarly after targeting left or right dorsal hippocampus in the IHKA model of TLE, distinct latent mechanisms based on lateralization of seizure focus may contribute to produce similar emergent reproductive endocrine outcomes.Significance StatementPeople with epilepsy often develop comorbidities dependent on the side of the brain in which the seizures originate. However, the mechanisms linking laterality of seizure initiation side to different comorbidities are unknown. Here, we examined whether injection of kainic acid in the left or right hippocampus, a model of temporal lobe epilepsy, produces differential effects on hippocampal damage, weight gain, and measurements of female reproductive endocrine function in female mice. We found that hippocampal sclerosis, pituitary gene expression, and weight gain are influenced by the side of injection. These results are the first demonstration of changes in pituitary gene expression in a model of epilepsy and indicate that the hemisphere targeted in the intrahippocampal kainic acid model impacts phenotypic outcomes.
