Malignancy and "Violated Neck" Rates in Consecutive Cohort of 79 Adult Patients With Solitary Cystic Neck Mass-Lessons Learned and Recommendations for Clinical Practice Guidelines

OBJECTIVE

The neck region is a common site for solitary cystic neck mass (SCNM) of various etiologies, including congenital, inflammatory, and neoplastic. In adults, the primary focus is excluding malignancy. The objective of this study was to retrospectively analyze the accuracy of available diagnostic technologies for the differentiation of benign and malignant SCNM in adult patients. The study aimed to develop new clinical practice guidelines for evaluating and managing SCNM.

METHODS

The primary predictive variables were the diagnostic utilities of fine-needle aspiration cytology (FNAC), ultrasound (U/S), multislice computed tomography, and magnetic resonance imaging. The study's endpoint was the overall diagnostic accuracy in differentiating between benign and malignant SCNM. The final diagnosis was based on histopathology.

RESULTS

The study included 79 adult patients: 55 (69.62%) male and 24 (30.38%) female (P<0.05). The mean age at presentation was 42.1 years (range: 18-84 years). Solitary cystic neck mass was distributed in the anterior neck region in 30 (37.97%) patients and the posterolateral neck regions in 49 (62.03%) patients (P<0.05). The posterolateral neck regions had a significantly higher rate of malignant SCNM than the anterior neck region [19/49 (38.78%) versus 1/30 (3.33%)] (P<0.05). There was no statistically significant difference between the U/S+FNAC and U/S+FNAC+multislice computed tomography and/or magnetic resonance imaging groups in differentiating benign and malignant SCNM (40/42 versus 36/37, P>0.05). "Violated neck" was recorded in 2 cases.

CONCLUSION

A systematic investigation protocol should be applied to evaluate adult patients with SCNM.

Aesthetic and Functional Outcomes of Upper Blepharoplasty Combined with Dacryoadenopexy in Lacrimal Gland Prolapse

INTRODUCTION

Lacrimal gland prolapse (LGP) is a term used to describe a benign, anterior displacement of the lacrimal gland. If this condition is not properly addressed during upper blepharoplasty, the aesthetic and functional results are less than optimal. This study aimed to report the surgical outcomes of upper blepharoplasty combined with dacryoadenopexy in patients with LGP.

METHODS

We reported an unusual case of severe LGP in a young patient. In addition, we performed a systematic review of the English literature on surgical cases of LGP published between 1973 and 2023. Eligible articles were analyzed for individual patient data (IPD) and aggregate patient data (APD). The primary predictor variable was the surgical technique used for lacrimal gland repositioning/suspension. The primary outcome variable was relapse rate.

RESULTS

The bibliographic search retrieved 488 surgical cases of LGP: 12 in IPD, and 476 in APD datasets. The relapse rates in the IPD and APD cohorts were 8.3% (1/12) and 1.2% (6/476), respectively. Within the APD dataset, no significant difference in the relapse rates between dacryoadenopexy via suture suspension and Whitnall's ligament suspension (5/409 and 1/20, respectively; P > 0.05) was observed. Light cauterization of the lacrimal gland capsule and surrounding soft tissues was performed in mild LGP cases (< 4 mm prolapse), with a relapse rate of 0% (0/47).

CONCLUSION

Upper blepharoplasty combined with dacryoadenopexy proved to be a safe surgical procedure with very satisfactory aesthetic outcome and minimal relapse rate.

Harmonic Scalpel-Assisted Endonasal Endoscopic Resection of the Vascular Tumors of the Anterior Skull Base

Vascular tumors represent a challenging pathologic subset for surgical treatment as they show a propensity for profuse bleedings. This is especially applicable to the skull base region, where surgical access is difficult due to its complex anatomy. To overcome this problem, the authors introduced the use of a harmonic scalpel in endoscopic skull base surgery for vascular tumors. Here, the authors report the outcomes of endoscopic harmonic scalpel-assisted surgery in 6 juvenile angiofibromas and 2 hemangiomas. All surgeries were performed using Ethicon Endo-Surgery HARMONIC ACE 5 mm Diameter Shears. The median intraoperative blood loss was 400 mL (range: 200-1500 mL). The median length of hospital stay was 7 days (range: 5-10 days). Recurrence was recorded in 1 patient with juvenile angiofibroma, which was successfully resolved with revision surgery. In this institutional experience, ultrasonic technology showed precise cutting with minimal bleeding, resulting in reduced surgical morbidity compared with conventional endoscopic instruments.

Patho-Anatomic Spectrum of Branchial Cleft Anomalies: Proposal of Novel Classification System

PURPOSE

Histogenesis, nomenclature, and classification of branchial cleft anomalies (BCAs) have been subjects of controversy for decades. The purpose of this study was to investigate the accuracy of current developmental theories (congenital, lymph node, and hybrid branchial inclusion theories) in defining the anatomic and histopathological characteristics of BCAs.

METHODS

Ninety consecutive patients with BCAs who underwent surgical excision were enrolled in this 2-center retrospective cohort study.

RESULTS

The present study included 90 patients: 46 (51.11%) women and 44 (48.89%) men (P > .05). The mean age at presentation was 31.89±17.31 years. Altogether, 92 BCAs were identified within the study population including 49 (53.26%) on the left side and 43 (46.74%) on the right side (P > .05). The BCAs included 79 (85.87%) branchial cleft cysts, 11 (11.96%) branchial cleft sinuses, and 2 (2.17%) branchial cleft fistulae. Three (3.26%) BCAs were distributed in the head regions, 88 (95.65%) in the neck regions, and 1 (1.09%) in the thoracic cavity. Following surgery, lymphoepithelial tissue was detected in the histopathological examination in 83 (90.22%) BCAs. The hybrid branchial inclusion theory exhibited significantly higher accuracy in defining patho-anatomic characteristics of BCAs than the branchial apparatus, precervical sinus, thymopharyngeal, and inclusion theories (90.22, 9.78, 2.17, 0.00, and 0.00%; respectively) (P < .05).

CONCLUSION

The novel branchial node (BN) classification system based on the hybrid branchial inclusion theory appears to be superior to other classification systems in determining the patho-anatomy of BCAs.

Dirofilaria repens microfilaremia in humans: Case description and literature review

Introduction

Dirofilaria repens is a vector-borne filaroid helminth of carnivorous animals, primarily domesticated dogs. Humans are considered to be accidental hosts in which D. repens rarely reach sexual maturity but induce local inflammation, mainly in subcutaneous and ocular tissues.

Methods

In the current study, we present the detection of multiple adults of D. repens, endosymbiont Wolbachia sp. and microfilariae by molecular analysis in peripheral tissues and bloodstream of a human host. A subsequent meta-analysis of published literature identified 21 cases of human infection with adult D. repens producing microfilariae.

Results

Within the study population, there were 13 (59.09%) males, eight (36.36%) females and, in one (4.55%) case, sex was not reported. A total of 11 (50.00%) cases had subcutaneous dirofilariasis, six (27.27%) had ocular dirofiliariasis, with single cases (4.55% each) of genital, mammary, lymphatic and a combination of subcutaneous and pulmonary dirofilariasis described. In one (4.55%) case, the primary anatomical site of adult D. repens could not be found. D. repens microfilariae were detected in the local tissue (local microfilariasis) in 11 (50.00%) cases and the peripheral blood (microfilaremia) in 11 (50.50%) cases. Final identification of D. repens microfilariae was based on morphological detection in 14 (63.64%) cases, and molecular detection in eight (36.36%) cases.

Conclusion

The results of this study suggest that humans may act as a final host for D. repens, however its role as a source of D. repens infection is less clear.

•

Humans may act as a final host for D. repens

•

Immunodeficiency is not a risk factor for human D. repens microfilaremia.

•

Surgical extirpation of adult D. repens is a mainstay of treatment.

Comorbidity of Chronic Tinnitus and Psychological Stress - Which Came First, the Chicken or the Egg?

Subjective tinnitus is a frequent, debilitating hearing disorder causing severe emotional stress and psychological suffering. Likewise, many reports show that the onset of tinnitus occurs at the time of high stress or after a period of stress. It is also common for existing tinnitus to become worse during exposure to stress. However, in clinical practice the association between tinnitus and stress is often neglected. Extensive search of the Web of Science database has shown a low ratio of scientific articles about coexistence of stress and tinnitus compared to other stress-related conditions. Specifically, there are about sixteen times more articles investigating comorbid stress in chronic pain, about six times more in chronic fatigue, and about four times more in fibromyalgia. Previous studies of biological markers of stress in tinnitus patients showed normal diurnal levels of stress hormone cortisol. However, experimental studies of tinnitus subjects showed a blunted reactive cortisol response after a psychosocial stress test, exposure to noise in the laboratory and a dexamethasone suppression test. In addition, tinnitus subjects showed increased sympathetic tone, and weakened sympathetic response after exposure to mental arithmetic task. In tinnitus subjects oxidative metabolism shows imbalance with shift from antioxidant enzyme preponderance towards oxidative stress predominance. Relaxation therapeutic programs reduce stress-sensitive immunological parameter tumor necrosis factor alpha. Although existing data indisputably proves existence of comprehensive connections between tinnitus and psychological stress, there is still no empirical evidence to show whether stress as a etiological, or just contributing factor. Further research should give the ultimate answer on this subject.

Cranial polyneuropathy caused by herpes zoster infection: a retrospective single-center analysis

PURPOSE

Cranial polyneuropathy (CP) is a rare complication of herpes zoster (HZ) infection. This entity often produces situations of a diagnostic dilemma, as can be seen in a wide spectrum of clinical presentations. The aim of this study was to report the clinical characteristics, treatment, and outcomes of 11 patients from a single-institution experience.

METHODS

A retrospective analysis of patients treated for HZ CP over a 12-year period was performed.

RESULTS

The present study included 11 patients with CP caused by HZ infection-7 (63.63%) females, and 4 (36.36%) males. The mean age at presentation was 63 years (range, 38-85 years). Cranial nerve VII was affected in nine (81.82%) cases, CN VIII in six (54.55%) cases, CN V in five (45.45%) cases, CN III and IX in two (18.18%) cases, and CN VI and X in one (9.09%) case. The treatment of choice was acyclovir in all patients, while corticosteroids were administered in six (54.55%) patients. Complete CN recovery was observed in seven (63.63%) patients, while four (36.36%) patients suffered from permanent CN damage-two (18.18%) CN VII, one (9.09%) CN VII and VIII, and one (9.09%) CN VI.

CONCLUSION

Herpes zoster CP presents an interesting diagnostic and therapeutic challenge. Successful management of these patients depends on a thorough knowledge of the anatomy and topodiagnostic of CNs. Early administration of antiviral agents is crucial in terms of responsiveness to treatment and expedite recovery.
