Abstract
Carotid body tumors are slow growing neck masses that arise from the neural crest cells at the carotid bifurcation. Majority are asymptomatic and are diagnosed incidentally. Surgical excision is accepted as the treatment of choice to reduce complications. In the present series, we report 10 cases of carotid body tumors and our institutional experience. All patients underwent radiological evaluation with an ultrasonography with Doppler, contrast enhanced computed tomography and MR angiography. 6 cases were operated by a transcervical excision. The tumor was excised in tototranscervically. One of the cases required saphenous vein graft intraoperatively due to vascular injury and also had postoperative vocal cord palsy. The rest had an uneventful recovery. Carotid body tumors although rare and seemingly indolent can cause substantial symptoms if left untreated. A prompt multi modality approach is needed for both diagnosis and treatment to avoid major complications.

Abstract
The carotid body (CB) is the main peripheral arterial chemoreceptor that registers the levels of pO2, pCO2 and pH in the blood and responds to their changes by regulating breathing. It is strategically located in the bifurcation of each common carotid artery. The organ consists of "glomera" composed of two cell types, glomus and sustentacular cells, interspersed by blood vessels and nerve bundles and separated by connective tissue. The neuron-like glomus or type I cells are considered as the chemosensory cells of the CB. They contain numerous cytoplasmic organelles and dense-cored vesicles that store and release neurotransmitters. They also form both conventional chemical and electrical synapses between each other and are contacted by peripheral nerve endings of petrosal ganglion neurons. The glomus cells are dually innervated by both sensory nerve fibers through the carotid sinus nerve and autonomic fibers of sympathetic origin via the ganglioglomerular nerve. The parasympathetic efferent innervation is relayed by vasomotor fibers of ganglion cells located around or inside the CB. The glial-like sustentacular or type II cells are regarded to be supporting cells although they sustain physiologic neurogenesis in the adult CB and are thus supposed to be progenitor cells as well. The CB is a highly vascularized organ and its intraorgan hemodynamics possibly plays a role in the process of chemoreception.

Abstract
This chapter describes the history of the carotid body (CB) and the subsequent research on its structure and function. The chronological development of ideas about its anatomical structure as a ganglion, the first descriptions of its glandular nature as a ball of highly vascular tissue (glomus), the discovery of its neural crest origin and relevant embryological views as a true paraganglion toward a more conclusive understanding of its sensory nature as a chemoreceptor for chemical changes in blood have been consistently demonstrated. The knowledge of the CB neurochemistry, physiology and pathophysiology has progressed immensely in the past century and a large and compelling body of evidence for the presence of a neurogenic niche in the CB has accumulated over the last two decades, thus underlying its function and possibility for the development of cell replacement therapies.

Abstract
The carotid body (CB) is the main peripheral chemoreceptor for arterial respiratory gases O2 and CO2 and pH, eliciting reflex ventilatory, cardiovascular, and humoral responses to maintain homeostasis. This review examines the fundamental biology underlying CB chemoreceptor function, its contribution to integrated physiological responses, and its role in maintaining health and potentiating disease. Emphasis is placed on 1) transduction mechanisms in chemoreceptor (type I) cells, highlighting the role played by the hypoxic inhibition of O2-dependent K+ channels and mitochondrial oxidative metabolism, and their modification by intracellular molecules and other ion channels; 2) synaptic mechanisms linking type I cells and petrosal nerve terminals, focusing on the role played by the main proposed transmitters and modulatory gases, and the participation of glial cells in regulation of the chemosensory process; 3) integrated reflex responses to CB activation, emphasizing that the responses differ dramatically depending on the nature of the physiological, pathological, or environmental challenges, and the interactions of the chemoreceptor reflex with other reflexes in optimizing oxygen delivery to the tissues; and 4) the contribution of enhanced CB chemosensory discharge to autonomic and cardiorespiratory pathophysiology in obstructive sleep apnea, congestive heart failure, resistant hypertension, and metabolic diseases and how modulation of enhanced CB reactivity in disease conditions may attenuate pathophysiology.

Abstract
The ageing process is characterized by a decline in several physiological functions resulting in a reduced capability to maintain homeostasis. The lowered homeostatic capacity seems to involve the carotid body (CB), whose role is to modulate ventilation and tissue oxygen supply. It thus plays a prime role in all ageing processes. Ageing causes marked changes in CB morphology. In older animals, it is enlarged and shows a concomitant decrease in the percentage of chemoreceptor tissue, as well as a proliferation of type II cells. The carotid glomitis is present with aggregates of lymphocytes and fibrosis of the lobules. Type I cells are dehydrated, with a profound vacuolization, a shrinking nucleus, and lipofuscin accumulation. With increased age, human CB shows a reduction in the number and volume of mitochondria, fewer synaptic junctions between glomi, along with a reduction in CB content of neurotransmitters, leading to a sort of 'physiological denervation'. Ageing could be interpreted as a cumulative result of oxidative damage to cells, which derives from aerobic metabolism. Moreover, metabolic rate is tightly correlated with life duration; thus a loss in mitochondrial function is one of the prime factors affecting CB ageing processes. The age-related reduction in synaptic junctions might be a self-protective mechanism through which cells buffer themselves against an accumulation of reactive oxygen species. The correlation between hypoxia and the life duration of CB cells remains an open question until how and why cells sense oxygen is understood.

Abstract
AbstractBackground:Head and neck paragangliomas are rare. They are usually slow-growing, benign, non-catecholamine secreting tumours, traditionally treated with surgical excision. Complications of surgical excision include lower cranial nerve palsies, stroke and death.Method:A retrospective case note analysis was conducted of patients with head and neck paragangliomas treated with a watch-and-scan policy from March 2003 to September 2015, and the relevant literature was reviewed.Results:Fifteen head and neck paragangliomas were identified. None of the patients developed a new lower cranial nerve palsy or progression of their presenting hearing loss during the follow-up period. Five patients displayed an increase in maximum linear dimension of 4 mm over an average of 57.4 months. A review of the literature showed that a watch-and-surveillance scan policy is evolving as a treatment option for head and neck paragangliomas without malignant risk factors.Conclusion:Readily available surveillance scanning in head and neck paragangliomas enables the monitoring of head and neck paragangliomas, which may allow for avoidance of major surgery.

Abstract
Studies on experimental animals established that the carotid bodies are sensory organs for detecting arterial blood O2 levels and that the ensuing chemosensory reflex is a major regulator of cardiorespiratory functions during hypoxia. However, little information is available on the human carotid body responses to hypoxia. The present study was performed on human carotid bodies obtained from surgical patients undergoing elective head and neck cancer surgery. Our results show that exposing carotid body slices to hypoxia for a period as brief as 5 min markedly facilitates the release of ACh and ATP. Furthermore, prolonged hypoxia for 1 h induces an increased release of interleukin (IL)-1β, IL-4, IL-6, IL-8 and IL-10. Immunohistochemical analysis revealed that type 1 cells of the human carotid body express an array of cytokine receptors as well as hypoxia-inducible factor-1α and hypoxia-inducible factor-2α. Taken together, these results demonstrate that ACh and ATP are released from the human carotid body in response to hypoxia, suggesting that these neurotransmitters, as in several experimental animal models, play a role in hypoxic signalling also in the human carotid body. The finding that the human carotid body releases cytokines in response to hypoxia adds to the growing body of information suggesting that the carotid body may play a role in detecting inflammation, providing a link between the immune system and the nervous system.

Abstract
Paraganglioma is a rare neoplasm arising from carotid body usually benign and constitute 0.5 % of all total body tumors. They constitute 60-70 % of head and neck paraganglioma and resemble other paragangliomas of the body like glomus jugulare, glomus tympanicum, and pheochromocytoma. This is a retrospective analysis of the medical records of carotid body paraganglioma cases. Nine patients operated during the study period and the follow up traced were included in the study. Seven females and 2 males were analysed. Six had tumor on the left side and 3 had on the right side. All the cases surgical excision was done by a tranverse incision as 2 patients had Shamblin I, 5 patients had Shamblin II, and 1 patients Shamblin IIIa. All the Shamblin I had tumor away from the carotids and were easily dissected without vessel damage, a sub adventitial tumor excision was performed in all the 5 cases of Shamblin II, 1 case of Shamblin IIIa was dissected with difficulty without sacrificing or vessel reconstruction. Paraganglioma of the carotid body should be considered as a differential diagnosis for painless lateral neck masses. Larger tumors need a multidisciplinary team of head and neck with vascular surgeons for better results.

Abstract
The risk of severe altitude-induced diseases is related to ventilatory and cardiac responses to hypoxia and is dependent on sex, age and exercise training status. However, it remains unclear how ageing modifies these physiological adaptations to hypoxia. We assessed the physiological responses to hypoxia with ageing through a cross-sectional 20 year study including 4675 subjects (2789 men, 1886 women; 14-85 years old) and a longitudinal study including 30 subjects explored at a mean 10.4 year interval. The influence of sex, training status and menopause was evaluated. The hypoxia-induced desaturation and the ventilatory and cardiac responses to hypoxia at rest and exercise were measured. In men, ventilatory response to hypoxia increased (P < 0.002), while desaturation was less pronounced (P < 0.001) with ageing. Cardiac response to hypoxia was blunted with ageing in both sexes (P < 0.001). Similar results were found in the longitudinal study, with a decrease in cardiac and an increase in ventilatory response to hypoxia with ageing. These adaptive responses were less pronounced or absent in post-menopausal women (P < 0.01). At exercise, desaturation was greater in trained subjects but cardiac and ventilatory responses to hypoxia were preserved by training, especially in elderly people. In conclusion, respiratory response to hypoxia and blood oxygenation improve with ageing in men while cardiac response is blunted with ageing in both sexes. Training aggravates desaturation at exercise in hypoxia, improves the ventilatory response and limits the ageing-induced blunting of cardiac response to hypoxia. Training limits the negative effects of menopause in cardiorespiratory adaptations to hypoxia.

Abstract
We report a case of familial, bilateral cervical paragangliomas (PGs) with lymph node metastasis. Patient I-1 is a 56-year-old man with a right carotid body tumor and a left vagal PG. Patient II-1 is a 29-year-old woman and the daughter of Patient I-1; she had a left carotid body tumor with regional lymph node metastasis. Histology of all the tumors showed the typical pattern of PGs, i.e., a zellballen pattern composed of chief cells positive for chromogranin A, and sustentacular cells positive for S100 protein. The Ki-67 labeling index was 1% to 3% in these PGs in both the primary and the metastatic tumors. Immunohistochemical analysis showed expression of somatostatin receptor (sstr) type 2A, but was negative for sstr type 5. Genomic mutation in succinate dehydrogenase type D was confirmed in both patients. Here, we present a case of familial PGs, and discuss the cases with special reference to pathologic diagnosis, genetics, and treatment.

Abstract
The respiratory response to hypoxia in mammals develops from an inhibition of breathing movements in utero into a sustained increase in ventilation in the adult. This ventilatory response to hypoxia (HVR) in mammals is the subject of this review. The period immediately after birth contains a critical time window in which environmental factors can cause long-term changes in the structural and functional properties of the respiratory system, resulting in an altered HVR phenotype. Both neonatal chronic and chronic intermittent hypoxia, but also chronic hyperoxia, can induce such plastic changes, the nature of which depends on the time pattern and duration of the exposure (acute or chronic, episodic or not, etc.). At adult age, exposure to chronic hypoxic paradigms induces adjustments in the HVR that seem reversible when the respiratory system is fully matured. These changes are orchestrated by transcription factors of which hypoxia-inducible factor 1 has been identified as the master regulator. We discuss the mechanisms underlying the HVR and its adaptations to chronic changes in ambient oxygen concentration, with emphasis on the carotid bodies that contain oxygen sensors and initiate the response, and on the contribution of central neurotransmitters and brain stem regions. We also briefly summarize the techniques used in small animals and in humans to measure the HVR and discuss the specific difficulties encountered in its measurement and analysis.

Abstract
Remodelling of mitochondrial metabolism is a hallmark of cancer. Mutations in the genes encoding succinate dehydrogenase (SDH), a key Krebs cycle component, are associated with hereditary predisposition to pheochromocytoma and paraganglioma, through mechanisms which are largely unknown. Recently, the jumonji-domain histone demethylases have emerged as a novel family of 2-oxoglutarate-dependent chromatin modifiers with credible functions in tumourigenesis. Using pharmacological and siRNA methodologies we show that increased methylation of histone H3 is a general consequence of SDH loss-of-function in cultured mammalian cells and can be reversed by overexpression of the JMJD3 histone demethylase. ChIP analysis revealed that the core promoter of IGFBP7, which encodes a secreted protein upregulated after loss of SDHB, showed decreased occupancy by H3K27me3 in the absence of SDH. Finally, we provide the first evidence that the chief (type I) cell is the major methylated histone-immunoreactive constituent of paraganglioma. These results support the notion that loss of mitochondrial function alters epigenetic processes and might provide a signature methylation mark for paraganglioma.

Abstract
Paragangliomas are hypervascular tumors arising from neural crest-derived paraganglia that are associated with the autonomic nerve system. Mutations in genes coding for subunits of mitochondrial complex II are associated with hereditary paragangliomas, and it has been suggested that these mutations result in a pseudohypoxic signal triggering tumorigenesis. Fibroblastic growth factors are hypoxia-inducible angiogenic stimuli that are involved in the angiogenesis and tumorigenesis of several neoplasms. It has been demonstrated that basic fibroblastic growth factor (bFGF) is a survival factor for cultured chief cells of the carotid body, capable of inducing proliferation. To examine the role of this growth factor in paragangliomas, we studied the immunohistochemical expression of bFGF and its high affinity receptor fibroblastic growth factor receptor 1 (FGFR1) in 7 normal carotid bodies and in 33 head and neck paragangliomas, including 2 malignant cases and their metastases. Immunohistochemical expression of bFGF and FGFR1 in tumors was confirmed by real-time polymerase chain reaction. FGFR1 was moderately present in carotid bodies, and there was strong and significantly enhanced cytoplasmatic staining of FGFR1 in all paragangliomas. Chief cells in carotid bodies and tumors showed strong cytoplasmatic staining for bFGF. The results indicate that FGFR1 and bFGF may contribute to the development of head and neck paragangliomas.

Abstract
Paragangliomas of the head and neck are highly vascular lesions originating from paraganglionic tissue located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). Diagnostic imaging can be considered in two clinical situations: (1) patients who present with clinical symptoms suggestive of a paraganglioma, and (2) individuals from families with hereditary paragangliomas. It is not only necessary to detect and characterize the lesion, but also to study the presence of multiplicity. For these purposes, MR imaging, and especially 3D TOF MRA, is the modality of choice. CT scanning is especially useful to show destruction of the temporal bone. Angiography in combination with embolization will mainly be used prior to surgical resection, but can also be used for diagnostic purposes when the diagnosis is not yet clear. Many parameters play a role in the decision to treat of which multifocality and impairment of cranial nerves are the most important. The primary therapeutic option for paragangliomas is complete excision of tumor with preservation of vital neurovascular structures. Resection however, should be balanced against a more conservative "wait and scan" policy or palliative treatments such as radiotherapy.

Abstract
BACKGROUND: The carotid body paraganglioma (chemodectoma) is a relatively rare neoplasm of obscure origin. These are usually benign and commonly present as asymptomatic cervical mass. PATIENTS AND METHODS: Records of 12 patients (9 female and 3 male) with carotid body tumors treated between 1982 and 2003, treated at our center were retrospectively reviewed. Data on classification, clinical presentation, and surgical treatment were extracted from the case records. Surgical complications and treatment outcome were noted and survival was calculated by actuarial method. The literature on carotid body paraganglioma was reviewed. RESULTS: The average age of the patients was 52 years (range 30-78 years). Eight of these cases presented as a large asymptomatic non-tender neck mass, and two each presented with dysphagia, and hoarseness of voice. As per Shamblin classification seven of tumors were type II and 5 were types III. In 7 cases subadventitial tumor excision was performed, while in 5 associated resection of both external and internal carotid arteries was carried out. The artery was repaired by end-to-end anastomosis in one case, with Dacron graft in one case, and with saphenous vein graft in 3 cases. There was no operative mortality. After a mean follow-up of 6.2 years (range 6 months to 20 years), there were no signs of tumor recurrence in any of the cases. CONCLUSIONS: Surgical excision is the treatment of choice for carotid body paragangliomas although radiation therapy is an option for patients who are not ideal candidates for surgery. For the tumors that are in intimate contact with carotid arteries, the treatment by vascular surgeon is recommended.

Abstract
BACKGROUND Paragangliomas of the carotid bifurcation are rare and usually benign neoplasms arising from the carotid body chemoreceptors. The aim of this retrospective study was to report long-term results of carotid bifurcation paragangliomas treated in a single institution over a period of 20 years. The following variables are described: age, sex, localization, diagnostic workup, operative procedure, complications, proportion and characteristics of malignant tumors, and cure rates. METHODS Thirty-six patients,10 men and 26 women, were treated. Twenty-three patients had tumors on the right side, 10 patients had tumors on the left side, and three patients had bilateral tumors. All patients were symptomatic. The most common complaint was a neck mass that had been present for 1 to 144 months. All patients had diagnostic procedures done before treatment. The most widely used was ultrasonography (26 patients). Angiography was performed in 14 patients. RESULTS All patients underwent complete tumor resection. In three cases, resection of the internal carotid was necessary. In all patients who underwent internal carotid resection, immediate reconstruction was performed. No patients had postoperative strokes. Five patients had postoperative nerve palsies. During the follow-up period of 4 months to 12 years, no patients had local recurrence develop. Four patients had distant metastasis. CONCLUSION The complete removal of paragangliomas of the carotid bifurcation is effective with acceptable morbidity. All recurrences of the malignant tumors were distant metastasis.

Abstract
BACKGROUND Carotid body tumors (CBT) are rare, infrequently malignant vascular neoplasms that are near the carotid bifurcation. Surgical excision is the treatment of choice, but individual surgeons or an institution cannot accumulate sufficient expertise to evaluate their outcomes with confidence. Our purpose was to report outcomes of surgical procedures for CBT from a nationwide dataset. STUDY DESIGN Data were retrieved from the Nationwide Inpatient Sample from nonfederal hospital discharge abstracts. Data were queried for ICD-9-CM code 39.8, operations on the carotid body and vascular bodies, and code 38.2, carotid endarterectomy. Outcomes analyzed were length of stay, charges, and in-hospital mortality. RESULTS An estmated 4,601 operations were identified, 3,746 for CBT surgical procedures only, and in 855 a carotid endarterectomy was also performed. Overall morbidity was 3.3%. Mortality with CBT alone was 2.0% but was 8.8% if carotid endarterectomy was also performed. CBT surgical procedures are most commonly performed in western states where higher elevations are found. Women constituted 59% of the population; mortality for women was higher than for men (12.4% versus 7.9%). Mortality in urban teaching hospitals was 2.1% and in nonteaching hospitals 4.9%. CONCLUSIONS CBT surgical procedures are rare but are performed across a broad age spectrum. Mortality rate is low for patients having CBT alone but rises when CE is added. Women are more commonly affected and fare less well. Addition of CE to CBT surgical procedures and the resulting poor outcomes have not been previously described. Consideration should be given to referral of CBT patients to hospitals where mortality rates are low.

Abstract
Minimal morbidity occurs with resection of most carotid body tumors (CBT). With larger tumors significant injury to the cranial nerves has been reported. In order to assess the operative sequelae rate, 30 patients with CBT were reviewed. Sixteen patients either presented with bilateral carotid body tumors or had previously undergone a resection of the contralateral carotid body tumors, for a total carotid body tumor count of 46. Sixteen patients demonstrated a familial pattern while 14 were nonfamilial. Within the familial group, 14 of 16 presented with multiple paragangliomas as compared to 6 of 14 in the nonfamilial group. Tumor size ranged from 0.8 to 12 cm. Vascular replacement occurred in 2 of 20 patients with tumors < 5.0 cm, compared with 5 of 9 with tumors > 5.0 cm. Four patients lost cranial nerves with the resection: superior laryngeal nerve (SLN), 4; cranial nerve X, 1; cranial nerve XII, 1. Ten patients developed baroreceptor failure secondary to bilateral loss of carotid sinus function. First-bite pain occurred in 10 of 25 operative patients. Cranial nerve loss can be minimal with resection of carotid body tumors, however, baroreceptor failure and first-bite pain are postoperative sequelae that are often disregarded in the postoperative period.

Abstract
Paragangliomas of the head and neck region are usually slow growing, benign tumors. A considerable fraction has a positive family history, and the predisposing locus, PGL, has recently been assigned to 11q22-q23. The inheritance pattern of the disease suggests that PGL undergoes maternal genomic imprinting. We have investigated 26 tumor samples from 22 patients with head and neck paragangliomas for the occurrence of loss of heterozygosity (LOH) on all non-acrocentric autosome arms. LOH was found only on chromosome 11, with a marked clustering on the distal half of the q-arm. However, in many cases the resulting allelic imbalance relative to normal DNA was weak, suggesting that only part of the tumor showed this abnormality. In all eight cases where we were able to determine the parental origin, the allele undergoing loss was maternally derived. Clonality analysis with a polymorphic marker for the X-chromosome indicated that two of three informative female cases were polyclonal, although a number of tumors carry aneuploid stemlines in DNA flow cytometry. We conclude that either tumor heterogeneity or polyclonality may explain the partial allele loss events seen in certain cases.
