Both sexes showed increased IRI, reduced adiponectin/visceral fat mass ratio and higher ectopic deposition of lipids in the pancreatic tissue adipocytes. In pancreatic islets, NIC males showed lower PDX-1 expression while females had higher PDX-1 and GLUT2 expressions plus lower α2 adrenergic receptor. In the muscle, NIC offspring of both sexes showed reduction of GLUT4 expression; NIC males also had lower insulin receptor and pAKT expressions.

Thus, glycemic homeostasis and peripheral insulin signaling in adult offspring of both sexes are affected by nicotine exposure through the milk, increasing the risk for type 2 diabetes development.

Insulin-like growth factor-II (IGF2), a key regulator of cell growth and development, is tightly regulated in its expression by epigenetic control that maintains its monoallelic expression in most tissues. Biallelic expression of IGF2 resulting from loss of imprinting (LOI) has been reported in adrenocortical tumors. BTK inhibitor In this study, we wanted to check whether adrenocortical lesions due to PRKAR1A mutations lead to increased IGF2 expression from LOI and compare these findings to those in other benign adrenal lesions.

We compared the expression of IGF2 by RNA and protein studies in primary pigmented nodular adrenocortical disease (PPNAD) caused by PRKAR1A gene mutations to that in primary macronodular adrenocortical hyperplasia (PMAH) and cortisol-producing adenomas (CPA) that did not have any mutations in known genes. We also checked LOI in all lesions by DNA allelic studies and the expression of other components of IGF2 signaling at the RNA and protein level.

We identified cell clusters overexpressing IGF2 in PPNAD; although immunostaining was patchy, overall, by RNA and immunoblotting PPNAD expressed high IGF2 message and protein. However, this was not due to LOI, as there was no correlation between IGF2 expression and the presence of LOI.

Our data pointed to over-expression of IGF2 protein in PPNAD compared to other benign adrenocortical lesions, such as PMAH and CPA. However, there was no correlation of IGF2 mRNA levels with LOI of IGF2/H19. The discrepancy between mRNA and protein levels with regards to LOI points, perhaps, to different control of IGF2 gene expression in PPNAD.

Lingual thyroid glands are rare embryologic variants of undescended tissue centered in the base of the tongue. Despite notable size, many lingual thyroids can be asymptomatic, though intervention is warranted for progressive or emergent symptoms. We report a rare manifestation of a hemorrhagic lingual thyroid addressed with both interventional radiology and robotic techniques.

A previously asymptomatic 41-year old female presented to the emergency department with massive hematemesis after significant binge drinking and vomiting. Emergent intubation was performed and gastroenterology workup ruled out Mallory-Weiss tears or ruptured esophageal varices. Fiberoptic laryngoscopy and imaging revealed a bleeding tongue base mass concerning for malignancy.

Aberrant feeding vessels with identifiable blush were embolized by Neurointerventional Radiology and the patient underwent tracheostomy for airway protection. Lingual thyroid was confirmed by biopsy and the mass was definitively resected via transoral robotic surgery. The patient had no further bleeding events and was decannulated uneventfully.

Lingual thyroid glands can present with life-threatening hematemesis and obstruction that may masquerade as entities of vascular or neoplastic origin. Management encompasses multidisciplinary diagnostic confirmation, airway protection, and minimally invasive resection that minimizes functional morbidity.

Among all mutations, nonsense mutations occurred in 45.7%, frameshift mutations in 32.9%, and splicing mutations in 19.5%. Small mutations were distributed throughout the whole dystrophin gene. Splicing mutations were twice more common in BMD patients than in DMD patients. Eighty-two percent of mothers of the males affected with DMD/BMD were found to be carriers of small mutations.

The aim of the study is to evaluate the ultrasonographic dimensional changes of the anterior belly of the digastric muscle (ABDM), occurring after intramuscular botulinum toxin A (BTX-A) injection during orthognathic surgery, in a series of five Class II malocclusion patients.

All the patients received 20 units of BTX-A, into both ABDM, intraoperatively. The length, width and cross-sectional area (CSA) of the ABDM were ultrasonographically measured at three different time points T

(preoperatively), T

(postoperatively at 2weeks after the surgical intervention), and T

(postoperatively at 6-9months).

A statistically significant higher length of the ABDM was noted postoperatively, at T

and T

compared to T

. The patients showed an increased length by 12.2% at 2weeks postoperatively and continued to increase, reaching 24.6% at 6months. A decreased width of ABDM by 6.5% at T

compared with T

was also found.

Postoperative ultrasound (US) follow-up measurements in patients with Class II malocclusion, orthognathic surgery and intraoperative BTX-A injection in the ABDM, showed dimensional changes of the muscle, with elongation and thinning.
