RESUMO
The aim of this study was to investigate and characterize the microbiome in bile samples obtained from dogs with gallbladder mucocele (6), cats with suspected cholangitis/cholangiohepatitis (4), as well as from healthy dogs (6) and cats (4). Our goal was to compare the microbiome patterns with clinical findings and bacterial culture results in diseases of the gallbladder and to identify a potential microbial biomarker of diseased groups. The microbial taxa composition revealed that Proteobacteria were the most dominant phylum in healthy and diseased individuals in all groups. Individuals from six families including Burkholderiaceae, Phyllobacteriaceae, Bradyrhizobiaceae, Sphingomonadaceae, Moraxellaceae, and Caulobacteraceae, constituted the core microbiome in the gallbladder of healthy dogs. A combination of LEfSe analysis and Taxa2ASV decomposer revealed that Pseudomonaceae and Ruminococcaceae exclusively occurred in the mucocele group. In conclusion, this study determined the core microbiome in the gallbladder of healthy dogs and the possible biomarkers (Pseudomonaceae and Ruminococcaceae) of gallbladder mucocele in dogs.
Le but de cette étude était d'étudier et de caractériser le microbiome dans des échantillons de bile obtenus auprès de chiens atteints de mucocèle de la vésicule biliaire (6), de chats suspectés de cholangite/cholangiohépatite (4), ainsi que de chiens (6) et de chats en bonne santé (4). Notre objectif était de comparer les modèles de microbiome avec les résultats cliniques et les résultats de cultures bactériennes dans les maladies de la vésicule biliaire et d'identifier un biomarqueur microbien potentiel des groupes malades. La composition des taxons microbiens a révélé que les protéobactéries constituaient le phylum le plus dominant chez les individus sains et malades de tous les groupes. Des individus de six familles, dont Burkholderiaceae, Phyllobacteriaceae, Bradyrhizobiaceae, Sphingomonadaceae, Moraxellaceae et Caulobacteraceae, constituaient le microbiome central de la vésicule biliaire de chiens en bonne santé. Une combinaison de l'analyse LEfSe et du décomposeur Taxa2ASV a révélé que les Pseudomonaceae et les Ruminococcaceae étaient exclusivement présentes dans le groupe des mucocèles. En conclusion, cette étude a déterminé le microbiome central de la vésicule biliaire de chiens en bonne santé et les biomarqueurs possibles (Pseudomonaceae et Ruminococcaceae) de la mucocèle de la vésicule biliaire chez le chien.(Traduit par Docteur Serge Messier).

Introduction: Mucocoele of the appendix occurs in 0.2-0.7% of people in the world without any well-defined clinical symptoms. It occurs when there is an accumulation of mucous in the lumen of the appendix. Case Presentation: We present three cases: a 48-year-old male admitted to the emergency room with a one-day history of right iliac fossa pain. Abdominal examination was suggestive of acute appendicitis. The initial abdominal computerised tomography scan was reported as being unremarkable. At surgery, a firm tumour of the appendix was found, and a limited right hemicolectomy was done. Histopathology confirmed a mucocoele of the appendix with borderline mucinous histology.The second case is a 63-year-old man who presented with a one-year history of abdominal distension and weight loss. Previous abdominal ultrasound was suggestive of liver cirrhosis with significant ascitic fluid. Abdominal magnetic resonance imaging found an appendix mucocoele with infiltration of the omentum and scalloping of the liver surface suggestive of pseudomyxoma peritonei. A percutaneous biopsy of the omental mass confirmed metastatic mucinous adenocarcinoma of the appendix.The third case is a 68-year-old man who, during an annual medical check-up, had an incidental finding of a cystic right iliac fossa mass on ultrasound, confirmed on abdominopelvic computerised tomography scan to be an appendix mucocele. He had laparoscopic appendicectomy. The histopathological diagnosis confirmed a mucinous cystadenoma of the appendix. Conclusion: Preoperative diagnosis of appendiceal mucocoele is difficult and commonly discovered intraoperatively. The prognosis is good for the histologically benign type, but it is poor when malignant or peritoneal lesions are present. Funding: None declared.

OBJECTIVES: Oral mucoceles are most frequently encountered on the lower lip. A variety of treatment options are currently employed, including surgical excision, pharmacological injections, and laser therapy. However, each of these approaches may introduce risks and potential complications. Clinical practice has demonstrated a potential for self-healing in lower lip mucoceles, making a conservative observational approach more appealing. This research is a prospective study aimed at evaluating the self-healing capacity of lower lip mucoceles. METHODS: In this prospective study, patients with mucoceles were encouraged to intentionally delay medical intervention and to wait for self-healing. Disappearance of the mucocele for at least 3 months was defined as self-healing. RESULTS: Thirty patients with lower lip mucoceles were included. With no intervention, 24 patients (80%) reported self-healing of lower lip mucoceles. The mean natural duration of the mucoceles was 3.63 (± 4.7; 1-24) months. After self-healing of the mucocele, the patients were followed up for 17.21 (± 9.45; 2-30) months and there were no reported recurrences. CONCLUSIONS: Lower lip mucoceles have a high potential for self-healing and patients may be routinely encouraged to wait for self-healing. CLINICAL RELEVANCE: The high self-healing rate observed in this study suggests that a conservative, non-interventional approach might be considered as the first-line management for lower lip mucoceles.

Mucous cyst is a benign but recurrent lesion. It is located on the dorsal surface of the digital extremity between the distal interphalangeal joint and the base of the nail. The nail is often affected by the cyst because of its topographical proximity. Nail plate deformity may even be the first obvious abnormality indicating the presence of a small mucous cyst or subungual cyst. Mucous cyst is associated with osteoarthritis of the joint, osteophytes probably being the main contributing factor. Surgical treatment by joint debridement and cyst removal is the most effective way of preventing recurrence.

BACKGROUND: Gallbladder disease in people is frequently associated with disorders of lipid metabolism and metabolic syndrome. A recently emergent gallbladder disease of dogs, referred to as mucocele formation, is characterized by secretion of abnormal mucus by the gallbladder epithelium and is similarly associated with hyperlipidemia, endocrinopathy, and metabolic dysfunction. The cause of gallbladder mucocele formation in dogs is unknown. METHODS: A prospective case-controlled study was conducted to gain insight into disease pathogenesis by characterization of plasma lipid abnormalities in 18 dogs with gallbladder mucocele formation and 18 age and breed matched control dogs using direct infusion mass spectrometry for complex plasma lipid analysis. This analysis was complemented by histochemical and ultrastructural examination of gallbladder mucosa from dogs with gallbladder mucocele formation and control dogs for evidence of altered lipid homeostasis of the gallbladder epithelium. RESULTS: Gallbladder mucocele formation in dogs carried a unique lipidomic signature of increased lipogenesis impacting 50% of lipid classes, 36% of esterified fatty acid species, and 11% of complex lipid species. Broad enrichment of complex lipids with palmitoleic acid (16:1) and decreased abundance within complex lipids of presumptive omega-3 fatty acids eicosapentaenoic (20:5) and docosahexaenoic (22:6) was significant. Severe lipidosis of gallbladder epithelium pinpoints the gallbladder as involved causally or consequently in abnormal lipid metabolism. CONCLUSION: Our study supports a primary increase in lipogenesis in dogs with mucocele formation and abnormal gallbladder lipid metabolism in disease pathogenesis.

Cholecystectomy is indicated for gallbladder mucoceles (GBM). Evaluating the patency of the biliary duct and precise biliary tree visualization is crucial for reducing the risk of compromised bile flow after surgery. Therefore, intraoperative cholangiography (IOC) is recommended during cholecystectomy to prevent biliary tract injury. Although indocyanine green (ICG) cholangiography has been extensively reported in human medicine, only one study has been conducted in veterinary medicine. Therefore, this study aimed to demonstrate the use of ICG for IOC to identify fluorescent biliary tract images and determine the patency of the common bile duct during cholecystectomy in dogs. This study comprised 27 dogs, consisting of 17 with gallbladder mucoceles (GBM) and 10 controls, specifically including dogs that had undergone elective cholecystectomy for GBM. ICG injection (0.25 mg/kg) was administered intravenously at least 45 minutes before surgery. During the operation, fluorescent images from cholangiography were displayed on the monitor and obtained in black-and-white mode for the comparison of fluorescence intensity (FI). The FI values of the gallbladders (GBs) and common bile duct (CBD) were measured using FI analyzing software (MGViewer V1.1.1, MetapleBio Inc.). The results demonstrated successful CBD patency identification in all cases. Mobile GBM showed partial gallbladder visibility, whereas immobile GBM showed limited visibility. Additionally, insights into the adequate visualization of the remaining extrahepatic biliary tree anatomy were provided, extending beyond the assessment of CBD patency and gallbladder intensity. Our study demonstrates the potential of fluorescent IOC using intravenous injection of ICG for assessing the patency of the cystic duct and common bile duct during cholecystectomy in patients with GBM, eliminating the need for surgical catheterization and flushing of the biliary ducts. Further research is warranted to investigate and validate the broader applicability of ICG cholangiography in veterinary medicine.

Maxillary sinus retention cysts (MRCs) are typically asymptomatic and require no treatment. An early 30s man presented with a decade-long history of severe left-sided chronic facial pain (CFP). Multiple prior treatments resulted in an edentulous patient with persistent pain. Imaging revealed a dome-shaped radiopaque change in the left maxillary sinus. History and clinical examination suggested persistent idiopathic facial pain, and doubts about the outcome of a surgical intervention were explained to the patient. Surgical removal of the MRC via lateral antrotomy led to complete symptom resolution of CFP. This case substantiates the importance of considering MRCs as a possible cause of CFP. It also emphasises the need for a systematic multidisciplinary approach in cases of unexplained CFP.

BACKGROUND: Orofacial cysts are pathologic cavities that could be symptomatic and may cause facial disfigurement. The only epidemiologic report of such lesions in Southeast Nigeria studied jaw cysts from 1987 to 1996. New studies reflecting recent research findings and classifications on the subject in Southeast Nigeria are lacking. AIM: To determine the prevalence and distribution of orofacial cysts in a tertiary hospital in Enugu, Southeast Nigeria. METHODS: A 10-year retrospective study of patients with orofacial cysts diagnosed by histology was carried out. RESULTS: Orofacial cysts constitute 9.5% (85) of 897 orofacial lesions identified. The male-to-female gender ratio was 1.2:1. The mean age (± standard deviation) at the onset of the cystic lesion was 28.58 (±16.98) years. Developmental odontogenic cysts 52.9% (45) and salivary cysts 18.8% (16) were the most common group of orofacial cysts. The most prevalent orofacial cysts were odontogenic keratocysts at 25.9% (22), mucoceles 16.5% (14), and dentigerous cysts 14.1% (12). Straw-colored aspirates 34.8% (16) and dark brown aspirates 28.3% (13) were the predominant cystic contents. The mandible 45.9% (39) and maxilla 27.1% (23) were the commonest sites for orofacial cysts, while the lip 9.4% (8) was the most frequent soft tissue site. A significant association exists between anatomical site and cyst type at a 95% confidence interval with P = 0.000, X2 = 247.17. Unilocular radiolucency 62.5% (20) and multilocular radiolucency 34.4% (11) were the most common radiographic features. CONCLUSION: Developmental odontogenic cysts particularly odontogenic keratocysts were most prevalent while mucocele was the most common soft tissue cyst.

OBJECTIVE: The purpose of this study was to identify whether age is associated with mucocele recurrence after excision. STUDY DESIGN: This retrospective cohort study consisted of 492 patients who underwent oral mucocele excision at Boston Children's Hospital from 2010 to 2022. Fisher's exact tests were used to assess the association between age and mucocele recurrence. An adjusted logistic regression model was run to evaluate the effect of age on mucocele recurrence while controlling for confounders. A P value < .05 was considered significant. RESULTS: Mucocele recurrence was observed in 24 cases (4.9%). There was a significant association between age and mucocele recurrence (2.2% for <7 years vs. 2.9% for 7 to <13 years vs. 9.2% for 13 to <18 years vs. 8.9% for >18 years; P = .005). Sex; history of behavioral disorders; mucocele size, duration, and location; suture technique; and type of anesthesia were not significantly associated with recurrence (P > .135). An adjusted logistic regression model verified a significant association between age and mucocele recurrence (odds ratio, 1.053; 95% confidence interval, 1.019-1.088; P = .035). CONCLUSIONS: Mucocele recurrence occurs infrequently in patients younger than 7 years and is most prevalent in the teenage to young adult patient population. For every year increase in age, the odds of mucocele recurrence increase by 5.3%.

BACKGROUND: The association of Human Papilloma Virus (HPV) and Human Syncytial Virus (HSV) infection with inflammatory and potentially malignant disorders of the oral cavity (OPMD) is unknown. The aim of this cross-sectional study was to stablish the expression of the p16INK4A and HSV proteins, to test potential correlation between those parameters in biopsies from clinically diagnosed oral lesions. METHODS: Immunochemical analysis of 211 formalin-fixed, paraffin-embedded (FFPE) blocks from 211 individuals was provided. The clinical diagnosis included in the research were Oral lichen planus (N = 30), Oral Leukoplakia (N = 13) Mucocele (N = 25), Erosion/ulceration/ inflammation of mucosa (N = 8), Overgrowth of mucosa (N = 135). RESULTS: Two hundred eleven analyzed FFPE samples resulted with the median age of 58.5 years (the average age 54.0 years and SD ± 17 years). The female/male ratio was 2.3 (69.7% vs 30.3% respectively). All the samples positive for HSV also expressed p16INK4A (p = 0.000), that's showed various levels of association with the diverse clinical diagnosis reaching the higher level in OM 49.1% (29 positive samples) and OLP 30.5% (18). p16INK4A was associated with OLP at 30.5% (18), and fibroma 30.5%. HSV expression was mostly present in fibroma at 47.6% (10 positive samples). CONCLUSION: HSV and p16INK4A positivity in relation to diagnosis of the biopsies showed statistically most often p16INK4A in OLP and fibroma. The results of co-expression of p16INK4A and HSV in mucocele and fibroma in oral mucosa suggest a cooperation between the molecular alterations induced by these two viruses. Squamous papilloma samples positive for p16INK4A were also positive for HSV, suggesting that the putative pro-oncogenic action of HSV could be an early event.

RATIONALE: Retroperitoneal benign cysts during pregnancy are extremely rare and often remain asymptomatic until they attain a very large size. Diagnosis typically relies on a pathological tissue biopsy. The decision to pursue 1-step or 2-step surgical treatment should be tailored to each individual case rather than generalized. PATIENT CONCERNS: This case report presents the unique scenario of a pregnant woman with a confirmed pregnancy complicated by a large retroperitoneal cyst. The patient had a retroperitoneal cyst during her initial pregnancy, which went undetected during the first cesarean section. However, it was identified during her second pregnancy by which time it had grown to 13.0 cmâ ×â 15.0 cmâ ×â 25.0 cm, and extended from the liver margin to right ovarian pelvic infundibulopelvic ligament. Consequently, it was removed smoothly during her second cesarean section. DIAGNOSES: Postoperative pathology results indicated a massive retroperitoneal mucinous cystadenoma. INTERVENTIONS: The giant retroperitoneal cyst was smoothly excised during the second cesarean delivery for 1-step surgical treatment. OUTCOMES: Under the combined spinal and epidural anesthesia, a live female infant was delivered at 38 3/7 gestational weeks and the neonatal weight was 3200g. Under general anesthesia with endotracheal intubation, the giant retroperitoneal cyst was excised smoothly without complications. LESSONS: The findings of this case report contribute to the understanding of the diagnostic modalities, surgical approaches and postoperative considerations of giant retroperitoneal cysts associated with pregnancy.

This case study systematically assessed diverse approaches to sinus augmentation in the presence of sinus pathology. Three patients were carefully selected and categorized as pseudocyst (PsC) (type 1), mucous retention cyst (MRC) smaller than 20 mm (type 2), and MRC larger than 20 mm in size (type 3). All patients underwent sinus augmentation procedures, with each case utilizing a unique surgical approach. Spontaneous drainage was performed for the patient with PsC (type 1), followed by uncomplicated sinus augmentation. For the patient with an MRC smaller than 20 mm (type 2), aspiration of the cyst contents preceded sinus augmentation. Conversely, the patient with a larger MRC (type 3) underwent cyst enucleation followed by sinus augmentation after complete recovery of the sinus membrane. No complications were noted in any of the cases, and follow-up revealed stable implant installation at the site of sinus augmentation. Within the constraints of this study, the choice of surgical procedure, whether involving spontaneous drainage, aspiration, or enucleation, should be guided by an anticipated pathologic diagnosis and the size of the sinus cyst. This informed approach empowers clinicians to make well-informed decisions for the best possible outcomes and sustained results. Overall, this study offers valuable insights for clinicians seeking to optimize sinus augmentation procedures in the presence of sinus pathology.

Mucocele-like lesions (MLLs) of the breast are rare lesions described as dilated, mucin-filled cysts associated with rupture and extracellular mucin in the surrounding stroma. These lesions are of clinical concern because they can coexist with a spectrum of atypical and malignant findings, including atypical ductal hyperplasia, ductal carcinoma in situ, and invasive carcinoma including mucinous carcinoma. Imaging findings of MLLs are nonspecific and varied, although the most common initial finding is that of incidental coarse heterogeneous calcifications on mammography. Occasionally, an asymmetry or mass may be found with or without calcifications, and such MLLs have a higher rate of upgrade to malignancy at excision. Pathology findings are often descriptive given the small sample received from percutaneous biopsy, and the primary consideration is to report any associated atypia, including atypical ductal hyperplasia. There is consensus in the literature that MLLs with atypia on biopsy should undergo excision because of the average reported 17.5% (20/114) upgrade rate to malignancy. The upgrade rate for MLLs without atypia averages 4.1% (14/341). Therefore, imaging surveillance may be a reasonable alternative to excision for MLLs with no atypia on a case-by-case basis. We review MLL imaging findings, pathology findings, and clinical management and present 3 cases from our institution to add to the literature on these rare lesions.

PURPOSE: To evaluate the clinical and aesthetic outcome of percutaneous injection of sclerosant agents to treat head and neck cystic malformations (HNCM) and to assess their recurrence rate based on histology and site. METHODS: Fifty-four subjects (mean age 46 years) with HNCM treated by percutaneous injection of sclerosant agents between January and December 2017 were included. Imaging and clinical data before and after the procedure were collected. Quality of Life Index, Pain Visual Analogue Scale, and Aesthetic Scale scores were measured to assess clinical and aesthetic outcomes. A size reduction of ≥ 70% assessed through the visual scale was considered significant. RESULTS: Of the 54 HNCM, there were 26 (48%) lymphatic malformations (LM), 13 (24%) salivary epithelial duct cysts of the parotid gland, 12 (22%) salivary mucoceles, and 3 (5%) branchial cysts. A significant size reduction and a satisfactory clinical-aesthetic outcome were observed in all types of LM. The number of reinterventions was significantly associated with the number of lesions (p < 0.001). The lowest number of interventions was observed in macrocystic lymphatic malformations (average of 1.2 interventions). All salivary epithelial duct cysts showed a significant reduction in size, a satisfactory clinical-aesthetic outcome, and an average of 1.16 interventions per patient. Mucoceles had a worse response, with only 3/14 patients showing a satisfactory and long-lasting clinical outcome (average of 1.16 interventions). Treatment of branchial cysts showed the worst outcome with a limited clinical response (3/3). CONCLUSION: Percutaneous injection of sclerosant agents may be considered as a first-line treatment for LM and salivary epithelial duct cysts.

BACKGROUND: Different imaging techniques, such as multi-detector computed tomography (MDCT) scan and cone beam computed tomography(CBCT), are used to check the structure of the nose before rhinoplasty. This study aimed to evaluate the accuracy of two imaging techniques, MDCT scan, and CBCT, in diagnosing structural Variations in rhinoplasty for the first time. METHODS: This diagnostic accuracy study was conducted on 64 rhinoplasty candidates who complained of snoring and sleep apnea or had a positive result in the examination with Cottle's maneuver or modified Cottle technique between February 2021 and October 2022 at 15- Khordad Hospital affiliated to Beheshti University of Medical Sciences. Before rhinoplasty, patients were randomly assigned to one of the CT and CBCT techniques with an equal ratio. Scans were assessed for the presence of Nasal septum deviation (NSD), Mucocele, Concha bullosa, and nasal septal spur by two independent radiologists. The findings of the two methods were evaluated with the results during rhinoplasty as the gold standard. RESULTS: NSD was the most common anatomical variation based on both imaging techniques. The accuracy of CBCT for diagnosing Nasal Septum Deviation and Mucocele was 80% and 75%, respectively. The sensitivity, specificity, and accuracy of CBCT in detecting Concha bullosa were 81.3% and 83.3%, respectively. The Kappa coefficient between CBCT and intraoperative findings for diagnosing NSD and Concha Bullosa was 0.76 and 0.73, respectively (p < 0.05). CONCLUSION: CBCT can be considered a suitable method with high accuracy and quality to evaluate the anatomical variations before rhinoplasty.

BACKGROUND: Information is limited regarding the prevalence and importance of hepatic histologic abnormalities in dogs with gallbladder mucocele (GBM). OBJECTIVES: To (a) report prevalence of hepatic histologic abnormalities in dogs with GBM (b) evaluate for association between hepatic abnormalities and outcome in dogs with GBM (c) evaluate whether neutrophil-to-lymphocyte ratio (NLR) differs in dogs with GBM with and without specific hepatic lesions. ANIMALS: Fifty-two dogs with grossly and histologically confirmed GBM. METHODS: Multicenter, retrospective study of dogs with GBM undergoing cholecystectomy with concurrent liver biopsy. Archived histological sections of gallbladder and liver evaluated by investigators blinded to data. Proportions of dogs with each histologic abnormality alive vs deceased at 1, 3, and 12 months post-cholecystectomy compared. Mann-Whitney U performed to determine if NLR differed in dogs with or without selected lesions. RESULTS: 51/52 (98%, 95% CI [89%, 99%]) dogs with GBM had at least 1 hepatic histologic abnormality. Hepatic fibrosis (37/51; 73%, 95% CI [59%, 83%]), biliary hyperplasia (29/52; 56%, 95% CI [42%, 68%]), and portal inflammation (25/52; 48%, 95% CI [35%, 61%]) were most common. The proportion of dogs alive vs dead differed based on the fibrosis score at 1, 3, and 12 (P ≤ .04) months post-cholecystectomy. Dogs with hepatic necrosis (P = .006) and cholangitis/cholangiohepatitis (P = .02) had higher NLRs compared to dogs without these lesions. CONCLUSIONS AND CLINICAL IMPORTANCE: Histologic abnormalities of the liver are common in dogs with GBM. A higher portal fibrosis score might be associated with shortened long-term survival after cholecystectomy for dogs with GBM. An increase in NLR might predict hepatic necrosis and cholangitis/cholangiohepatitis in dogs with GBM.
