OBJECTIVE: To observe the effects of thumbtack-needle embedding therapy of auricular acupuncture on gastrointestinal function and intestinal microflora in the patients with gastric cancer after operation, and to explore its mechanism. METHODS: A total of 80 patients with gastric cancer after radical operation were randomly divided into an observation group (40 cases, 3 cases discontinued) and a control group (40 cases, 3 cases discontinued). The patients of both groups received the perioperative care for accelerating recovery. Additionally, in the observation group, the thumbtack-needle embedding therapy of auricular acupuncture was delivered at the auricular points of unilateral side, including Wei (CO₄), Pi (CO₁₃), Dachang (CO₇), Xiaochang (CO₆), Yuanzhong (AT_2,3,4i), Erzhong (HX₁), Sanjiao (CO₁₇) and Jiaowozhong (TF₃), and the needles were embedded and retained for 72 h. The postoperative recovery time of gastrointestinal function (the postoperative bowel sound recovery time, the first exhaust time, the first defecation time), the postoperative hospital stay and pain visual analogue scale (VAS) score were observed in the two groups. Before operation and on day 5 after operation, the serum gastrin level was detected in the two groups. The third-generation 16S rRNA sequencing technology was used to detect the composition and relative abundance of intestinal flora in the two groups before and after operation. RESULTS: Compared with the control group, the postoperative bowel sound recovery time, the first exhaust time and the first defecation time were shortened in the observation group (P<0.05). In the observation group, the VAS scores at 24 h, 48 h, and 72 h after surgery were lower than those of the control group, respectively (P<0.05). There was no significant differences in postoperative hospital stay and serum gastrin level between the two groups (P>0.05). The alpha diversity analysis showed that the differences in Shannon index, Simpson index, Pielou_J index and Pd_fath index were not significant statistically after intervention between the two groups (P>0.05). After intervention, the community structure of the fecal sample was similar at each taxonomic level between the two groups, and although the proportion between species was various, the difference was not significant (P>0.05). After intervention, there were 55 species with the differences between the two groups, 17 species of them presented significant difference in relative abundance in the observation group and 38 species in the control group. Regarding the level of genus, the levels of Klebsiell and Enterobacter increased (P<0.05) and the level of Streptococcus decreased (P<0.05) in the observation group. The main microbial groups that played an important role were Coprobacillaceae, Sutterellaceae and Yersiniaceae in the observation group. KEGG function prediction indicated that the function of intestinal microflora was mainly associated with the cofactor and vitamin metabolism, carbohydrate metabolism, and amino acid metabolism. CONCLUSION The thumbtack-needle embedding therapy of auricular acupuncture improves the postoperative gastrointestinal function of the patients with gastric cancer probably through regulating the structure and relative abundance of intestinal microflora and affecting the energy metabolism.

OBJECTIVE: To observe the clinical effect of acupuncture at yinsanzhen combined with auricular point sticking on primary dysmenorrhea (PDM). METHODS: Sixty patients with PDM were randomly divided into an observation group and a control group, with 30 cases in each group. Patients in the observation group were treated with acupuncture at yinsanzhen combined with auricular point sticking. The acupuncture was given at yinsanzhen (Guanyuan [CV4] and bilateral Guilai [ST29], Sanyinjiao [SP6]) once daily for 5 consecutive days. Auricular point sticking was applied to gan (CO₁₂), shen (CO₁₀), neifenmi (CO₁₈), etc. every other day, alternated between ears, totaling 3 sessions. All treatments were started 5 days before menstruation. Patients in the control group were treated with ibuprofen sustained-release capsules on the first day of menstruation for 3 consecutive days. Both groups were treated for 3 menstrual cycles. The scores of Cox menstrual symptom scale (CMSS) and visual analogue scale (VAS) were compared between the two groups before and after treatment and at the second menstrual cycle after treatment completion (follow-up). The serum contents of prostaglandin (PG) F2α and PGE2 were detected before and after treatment, and the clinical effect and safety of the two groups were evaluated. RESULTS: After treatment and during follow-up, the CMSS severity and duration scores and VAS scores of the two groups were lower than those before treatment (P<0.05 ), and the scores in the observation group were lower than those in the control group (P<0.05). After treatment, the serum contents of PGF2α were decreased, and the contents of PGE2 were increased (P<0.05) in the two groups. The total effective rate of the observation group was 93.3% (28/30), which was higher than 80.0% (24/30) of the control group (P<0.05). There were no adverse reactions in both groups. CONCLUSION Yinsanzhen combined with auricular point sticking can effectively improve the pain symptoms, relieve the degree of pain and shorten the duration of pain in patients with PDM, which may play a therapeutic role by reducing the content of serum PGF2α and increasing the content of serum PGE2.

This paper reports a case of red ear syndrome, a rare clinical condition, treated with acupuncture. At the initial consultation, the diagnosis was unclear from a western medical perspective. The advantage of traditional Chinese medicine in "prioritizing symptoms and syndrome differentiation" was fully utilized. Based on the patient's clinical manifestations, disease progression, tongue and pulse conditions, the treatment addressed the branch by targeting meridian qi stagnation based on the hand-taiyang sinew meridian theory, and treated the root by selecting acupoints according to syndrome differentiation for liver and kidney yin deficiency. A combined treatment of tendon needling and acupuncture produced immediate results after the first session. Subsequent sessions were administered every other day for a total of ten treatments. The patient's ear pain and redness symptoms had nearly disappeared, and a two-month follow-up showed good overall condition.

OBJECTIVE: To observe the clinical efficacy of auricular electroacupuncture for post-stroke dysphagia in the pharyngeal phase. METHODS: Eighty-two patients with post-stroke dysphagia in the pharyngeal phase were randomized into an auricular electroacupuncture group (41 cases) and a swallowing electrical stimulation group (41 cases, 1 case dropped out). In the auricular electroacupuncture group, electroacupuncture was applied at auricular points, i.e. Xin (CO₁₅) and Yanhou (TG₃), using disperse-dense wave, in frequency of 2 Hz/10 Hz, 30 min a time. In the swallowing electrical stimulation group, swallowing electrical stimulation was delivered for 30 min a time. Both groups were treated once daily for 4 weeks. The functional oral intake scale (FOIS) grade, as well as the hyolaryngeal complex displacement, the pharyngeal constriction rate (PCR) and the pharyngeal delay time (PDT) under video fluoroscopic study of swallowing (VFSS) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: Compared before treatment, the FOIS grade was improved (P<0.01), the forward and upward displacement amplitude of hyoid bone and thyroid cartilage was increased (P<0.05), and the PCR and PDT were decreased (P<0.05) after treatment in the two groups. After treatment, compared with the swallowing electrical stimulation group, the FOIS grade was superior (P<0.01), the upward displacement amplitude of hyoid bone and thyroid cartilage was larger (P<0.05) and the PCR and PDT were lower (P<0.05) in the auricular electroacupuncture group. The total effective rate was 85.4% (35/41) in the auricular electroacupuncture group, which was higher than 62.5% (25/40) in the swallowing electrical stimulation group (P<0.05). CONCLUSION Auricular electroacupuncture can effectively trigger pharyngeal initiation and improve post-stroke dysphagia in the pharyngeal phase.

Objective:To determine the association of demographic profiles and clinical characteristics of patients with aural foreign bodies seen at the Emergency Room (ER) of the East Avenue Medical Center with clinical outcomes

Methods:
Design:Cross-Sectional Study
Setting:Tertiary Government Training Hospital
Participants:A total of 143 aural foreign body cases seen at the ER from January to December 2022 under the Department of Otorhinolaryngology – Head and Neck Surgery (ORL-HNS) of East Avenue Medical Center were included in the study.

Results: Of the 143 patients, majority (84; 58.74%) were males. Mean age was 21.92 years old with two peak incidences noted at ages 1-12 years old and 18-65 years old. Most of the patients were right-handed (134; 93.71%). Majority of the foreign bodies were animate (76; 53.15%) and were frequently found to be lodged on the right ear (86; 60.14%) with duration from lodgment to
extraction commonly within less than 24 hours (119; 83.22%). One hundred forty two (99.30%) patients had successful foreign body extraction, 60 (41.96%) had complications, specifically involving the external auditory canal (51; 35.66%) and tympanic membrane (6; 4.20%). Significant associations were found between age and type of foreign body [χ2 (3, N =143) = 31.24, p < .01] with a higher proportion of animate foreign bodies in adults and inanimate foreign bodies in children; sex and presence of complications [χ²(1, N = 143) = 5.41, p < .05] with males experiencing more complications than females; type and duration of foreign body [, χ²(2, N = 143) = 16.33, p < .01] with animate foreign bodies generally having a shorter duration of less than 24 hours compared to inanimate foreign bodies; and the duration of foreign body and presence of TM complications [χ²(4, N = 143) = 14.21, p < .01] with shorter durations (less than 24 hours) showing fewer TM complications. Males had higher odds of developing complications compared to females (OR = 2.315, 95% CI [1.105, 4.851])

Although cisplatin is a widely used chemotherapeutic agent, it is severely toxic and causes irreversible hearing loss, restricting its application in clinical settings. This study aimed to determine the molecular mechanism underlying cisplatin-induced ototoxicity. Here, we established in vitro and in vivo ototoxicity models of cisplatin-induced hair cell loss, and our results showed that reducing STING levels decreased inflammatory factor expression and hair cell death. In addition, we found that cisplatin-induced mitochondrial dysfunction was accompanied by cytosolic DNA, which may act as a critical linker between the cyclic GMP-AMP synthesis-stimulator of interferon genes (cGAS-STING) pathway and the pathogenesis of cisplatin-induced hearing loss. H-151, a specific inhibitor of STING, reduced hair cell damage and ameliorated the hearing loss caused by cisplatin in vivo. This study underscores the role of cGAS-STING in cisplatin ototoxicity and presents H-151 as a promising therapeutic for hearing loss.

Noise-induced hearing loss is a worldwide public health issue that is characterized by temporary or permanent changes in hearing sensitivity. This condition is closely linked to inflammatory responses, and interventions targeting the inflammatory gene tumor necrosis factor-alpha (TNFα) are known to mitigate cochlear noise damage. TNFα-induced proteins (TNFAIPs) are a family of translucent acidic proteins, and TNFAIP6 has a notable association with inflammatory responses. To date, there have been few reports on TNFAIP6 levels in the inner ear. To elucidate the precise mechanism, we generated transgenic mouse models with conditional knockout of Tnfaip6 (Tnfaip6 cKO). Evaluation of hair cell morphology and function revealed no significant differences in hair cell numbers or ribbon synapses between Tnfaip6 cKO and wild-type mice. Moreover, there were no notable variations in hair cell numbers or hearing function in noisy environments. Our results indicate that Tnfaip6 does not have a substantial impact on the auditory system.

OBJECTIVE

To report a case of parotid cholesteatoma and concurrent squamous cell carcinoma of the temporal bone in a 51-year-old woman.

METHODS

Design: Case Report

Setting: Tertiary Government Training Hospital

Patient: One

RESULTS

A 51-year-old woman with a left parotid mass and ipsilateral external auditory canal mass and chronic bilateral otorrhea had parotid biopsy histological features of cholesteatoma and temporal bone imaging suggestive of middle ear cholesteatoma and possible parotid region abscess. She underwent subtotal petrosectomy, mastoid obliteration and excision of the parotid mass. Histopathological examination of the parotid mass was consistent with cholesteatoma but tissue from the middle ear cavity showed well-differentiated squamous cell carcinoma.

CONCLUSION

While cholesteatomas typically arise within the temporal bone, they may occasionally present in atypical or distant sites. In cases where a cholesteatoma demonstrates an unusual location, aggressive behavior, or atypical clinical progression, a high index of suspicion should be maintained for the possibility of an underlying or coexisting temporal bone squamous cell carcinoma.

OBJECTIVE

To describe a practical surgical approach for mastoid cavity obliteration and canal wall reconstruction using autologous bone dust and conchal cartilage applied either during primary canal wall up (CWU) surgery or in revision of prior canal wall down (CWD) mastoid cavities, with the aim of restoring a self-cleaning, waterproof ear that retained its natural acoustic resonance.

METHODS

The indications, surgical technique, and follow up and imaging surveillance were described, detailing patient selection, harvesting and application of autologous materials, and the key technical steps for cavity obliteration and posterior canal wall reconstruction. The importance of preserving the ear canal’s standing wave resonance (~2000–2500 Hz) for optimal hearing was emphasized. Postoperative monitoring with non-echo planar diffusion-weighted imaging (DWI) MRI was recommended at least 1.5 years after surgery to detect residual or recurrent cholesteatom.

RESULTS

This technique was performed successfully in 88 patients (32 males and 56 females, aged 6–80 years) across four hospitals in Metro Manila from January 2020 to July 2025. All patients had unremarkable postoperative courses and healed within three months. Among the 67 who underwent DWI MRI after 18 months, two required revision mastoidectomies with mastoid obliteration for cholesteatoma recidivism—one with residual and one with recurrent disease.

CONCLUSION

Mastoid obliteration and reconstruction using autologous bone dust and cartilage has proven to be a safe, effective and cost-efficient technique. It converts problematic open cavities into dry, self-cleaning ears suitable for swimming while preserving the acoustic benefits of a near-normal ear canal. Long-term follow-up with diffusion-weighted imaging (DWI) MRI is essential to ensure durable disease control.

Patient 1, a 3-year-6-month-old male, presented with feeding difficulties and delayed motor development. He exhibited poor responsiveness at birth, weak crying, intellectual and motor delays, low immunity, recurrent respiratory infections, hypotonia of the limbs, and distinctive facial features (low-set ears, double chin, and high arched palate), as well as a single transverse palmar crease on the right hand. Genetic testing revealed a c.1096C>T heterozygous variant in the SMARCB1 gene. Patient 2, a 3-year-old male, presented with developmental delay and distinctive facial features. Genetic testing identified the same pathogenic mutation as in Patient 1. The two patients are unrelated, and clinical phenotyping and genetic testing confirmed both cases as Coffin-Siris syndrome type 3. Coffin-Siris syndrome is a rare genetic disorder, and early genetic testing can aid in diagnosis.
