INTRODUCTION The recurrent laryngeal nerve gains its name because after branching from the vagus nerve, it turns superiorly (recur) around the subclavian artery on the right and around the ligamentum arteriosum on the left, the nonrecurrent nerve has a straight direct course to the larynx and doesn't follow this course. It presents mostly on the right side. The presence of this variation places the nerve at higher risk of injury during neck surgery especially thyroid operations. CASE PRESENTATION A 45-year-old lady presented with painless thyroid enlargement for 1 year. Thyroid examination showed a 3-cm firm nodule at the right thyroid lobe with normal thyroid function tests. Right thyroid lobectomy was done and the histopathology showed a benign follicular lesion. During surgery, we discovered 2 nonrecurrent laryngeal nerves at the right side which were arising from the vagus nerve and both were entering the larynx. CONCLUSION Failure in identification of the nerve or overlooking the possibility of the non-recurrent laryngeal nerve may result in a serious sequelae of nerve damage, ipsilateral injury may lead to permanent hoarseness and bilateral injury may result in severe dyspnea or aphonia. Currently, there are 3 types of nonrecurrent laryngeal nerve courses. Type 1 passes near to the superior thyroid vessels. Type 2 (2A) passes parallel to the inferior thyroid artery and has a transverse course above it. Type 3 (2B) passes parallel to the inferior thyroid artery and transversely between branches of or under the inferior thyroid artery, we can add to this classification type 4, which are 2 nonrecurrent laryngeal nerves (double nerves) passing above and parallel to the inferior thyroid artery.INTRODUCTION The most basic question to be answered in each case in which the choice of using a pressure equalization tube (PET) is being considered is "what is the underlying pathophysiology of the middle ear disease being addressed?" METHODS We will evaluate the hypothesis that the Eustachian Tube (ET) may become "dysfunctional" due to allergic mucosal edema and obstruction. We review the literature that evaluates the role of ET, the proposed affect that allergy may contribute to ET dysfunction (ETD), and the relation of allergic rhinitis to otitis. RESULTS Proof that allergy affects the middle ear was supported by (1) over a dozen investigators using objective immunotherapy demonstrating over the past 70 years that 72% to 100% of the children with otitis media with effusion (OME) are atopic, (2) an association of allergic Th2 immune-mediated histochemical reactivity within the target organ itself, (3) establishment that inflammation within the middle ear is truly allergic in nature, and (4) direct evidence of a dose-response curve and consistency of results, which confirm that OME resolves on allergy immunotherapy. CONCLUSION Current medical evidence should heighten the awareness of physicians of the physiology that underlies ETD. CDK activity The evidence supports the link between allergy and OME. The middle ear behaves like the rest of the respiratory tract, and what has been learned about the atopic response in the sinuses and lungs may be applied to the study of the immunologic mechanisms within the middle ear that lead to ETD requiring the use of PET.OBJECTIVES Recent studies suggest that elevated neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are poor prognostic factors in sudden sensorineural hearing loss (SSNHL). We aimed to investigate the accuracy of this hypothesis by taking into account the effect of cardiovascular risk (CVR) factors. METHODS Medical records of 122 patients with SSNHL were reviewed retrospectively and grouped into 2 as; patients without CVR (group 1; n = 68) and patients having CVR (group 2; n = 54). Moreover, 60 control cases who did not have SSNHL were also included and grouped into 2 as; group 3 (n = 30) with CVR and group 4 (n = 30) healthy controls without having SSNHL or CVRs. Neutrophil (N), lymphocyte (L), platelet (Plt), NLR, and PLR between the groups and their relationship with the severity of hearing loss, recovery rates, and audiogram configurations were analyzed. RESULTS The highest N and NLR values were in group 1 and were significantly higher than the values of group 4 (P .05). CONCLUSIONS Elevated levels of N and NLR may be considered as strong laboratory findings showing an inflammatory response in the diagnosis of SSNHL, but the presence of CVR factors does not seem to increase the inflammatory response in SSNHL as expected. In patients with SSNHL, NLR and PLR elevation may indicate better prognosis.Suboptimal lactation is a common, yet under-appreciated cause for early cessation of breastfeeding. Molecular regulation of mammary gland function is critical to the process lactation; however, physiological factors underlying insufficient milk production are poorly understood. CDK activity The zinc (Zn) transporter ZnT2 is critical for regulation of mammary gland development and maturation during puberty, lactation, and post-lactation gland remodeling. Numerous genetic variants in the gene encoding ZnT2 (SLC30A2) are associated with low milk Zn concentration and result in severe Zn deficiency in exclusively breastfed infants. However, the functional impacts of genetic variation in ZnT2 on key mammary epithelial cell functions have not yet been systematically explored at the cellular level. Here we determined a common mutation in SLC30A2/ZnT2 substituting serine for threonine at amino acid 288 (Thr288Ser) was found in 20% of women producing low milk volume (n=2/10), but was not identified in women producing normal volume. Exploration of cellular consequences in vitro using phosphomimetics showed the serine substitution promoted preferential phosphorylation of ZnT2, driving localization to the lysosome and increasing lysosome biogenesis and acidification. While the substitution did not initiate lysosome-mediated cell death, cellular ATP levels were significantly reduced. Our findings demonstrate the Thr288Sermutation in SLC30A2/ZnT2 impairs critical functions of mammary epithelial cells, and suggest a role for genetic variation in the regulation of milk production and lactation performance.
