INTRODUCTION AND IMPORTANCE
The paranasal sinuses are a group of four paired air-filled spaces located within the bony skull; maxillary, frontal, sphenoid, and ethmoid sinuses. Paranasal sinuses aplasia is a rare condition that is mainly confined to the frontal sinus unilaterally. Combined aplasia of multiple sinuses along with hypoplasia of other sinuses is extremely rare. This rare case should be considered in mind before scheduling any endoscopic sinus surgery to prevent complications during these surgeries.
CASE PRESENTATION
A 13-year-old male patient presented to our ENT clinic complaining of a prolonged history of persistent headache, nasal obstruction, and nasal discharge. He also complained of bilateral ears fullness and facial pain. On physical examination, bilateral purulent nasal discharge with congested inflamed nasal mucosa and both inferior turbinate. The patient was diagnosed to have sinusitis and was started on treatment. The patient returns to our clinic after several weeks with minimal improvement. Computed tomography (CT was obtained and showed completely absent pneumatization of bilateral frontal and sphenoid sinuses.
CLINICAL DISCUSSION
The development of the paranasal sinuses appears prenatally which can lead to a variety of PNS anomalies. However, the aplasia or hypoplasia of the PNS is found to be rare. Aplasia is mainly found in frontal and maxillary sinuses with a prevalence of 12 % and 6 %, respectively. While the prevalence of sphenoid sinus aplasia is extremely rare and found to be less than 0.7 %. Moreover, aplasia of multiple sinuses "combined aplasia" is an incredibly unusual finding.
CONCLUSION
this patient is one of the extremely rare cases of the combined aplasia of frontal and sphenoid sinuses who was diagnosed and confirmed at an early age without any skeletal, systemic, or hematological abnormalities. Despite that, this rare case should be considered in mind before scheduling any endoscopic sinus surgery to prevent complications during these surgeries.

Our objective was to describe associations of postpartum health with pregnancy and pregnancy loss (P-LOSS) from d 19 to 40 after first postpartum artificial insemination (AI) in lactating Holstein cows. In 2 commercial dairy herds in Ontario, Canada, 468 Holstein cows were enrolled 21 ± 3 d before expected parturition when body condition score (BCS) and lameness were assessed. Serum total Ca, haptoglobin (Hp), and nonesterified fatty acids (NEFA) were measured at 2 and 6 ± 2 d in milk (DIM). Blood β-hydroxybutyrate (BHB) measurement and metritis detection were done at 4, 8, 11, and 15 ± 2 DIM. Cows were examined for endometritis (ENDO; ≥11.5% polymorphonuclear cells in endometrial cytology) and purulent vaginal discharge (PVD) at 35 ± 3 DIM. Lameness was assessed again at 21 and 49 ± 3 DIM and BCS at 63 ± 3 DIM. First postpartum AI occurred primarily (86%) based on detection of estrus by activity monitors, on average (± standard deviation) at 65 ± 9 DIM, and the remaining cows received timed AI at 86 ± 18 DIM. Serum progesterone (P4) was measured on d 8 and 12 after AI, and pregnancy at first AI (P/AI) was estimated by the expression of ISG15 in peripheral blood leukocytes at d 19 after AI and by pregnancy-associated glycoprotein in serum at d 29, 33, and 40 after AI. Each metabolite (Ca, Hp, NEFA, and BHB) was categorized above or below a cut-point identified with receiver operating characteristic curve analysis associated with P/AI confirmed by ultrasound at d 33 from a larger data set. Data were analyzed using multivariable mixed logistic regression models, accounting for parity, health variables, covariates (season at calving and at AI, milk yield at first Dairy Herd Improvement Association test [categorized into terciles], AI method, and DIM), and herd. The proportions of cows classified pregnant at d 19, 29, 33, and 40 after AI were 64%, 54%, 50%, and 45%, respectively. At d 19 after AI, P/AI was less likely in cows diagnosed with ENDO (52% vs. 69%) or PVD (54% vs. 67%). At d 29, P/AI was less likely in cows with Hp ≥1.54 g/L at 2 DIM (38% vs. 55%) or PVD (35% vs. 56%). Both metritis and ENDO were associated with decreased P/AI at d 40 after AI. Cows diagnosed with metritis had greater risk of P-LOSS from d 19 to 29 (43% vs. 22%) or from d 33 to 40 (37% vs. 7%) than cows without metritis. From d 29 to 33, the risk of P-LOSS was greater in cows with NEFA ≥0.73 mM at 2 DIM (13% vs. 5%) or BCS ≤2.75 at 63 DIM (14% vs. 5%). The concentration of P4 on d 8 after AI was positively associated with P/AI at d 29, 33, and 40, and negatively associated with P-LOSS from d 19 to 29. Postpartum health disorders, particularly reproductive tract disease, can have detrimental effects on early pregnancy establishment and on pregnancy maintenance from d 19 to 40 after AI.

Silicone breast implant insertion is a commonly performed surgical procedure for breast augmentation or reconstruction. Among various postoperative complications, infection is one of the main causes of patient readmission and may ultimately require explantation. We report a case of infective costochondritis after augmentation mammoplasty, which has rarely been reported and is therefore difficult to diagnose. A 36-year-old female visited the clinic for persistent redness, pain, and purulent discharge around the left anteromedial chest, even after breast implant explantation. Magnetic resonance imaging showed abscess formation encircling the left fourth rib and intracartilaginous and bone marrow signal alteration at the left body of the sternum and left fourth rib. En bloc resection of partial rib and adjacent sternum were done and biopsy results confirmed infective costochondritis. Ten months postoperatively, the patient underwent chest wall reconstruction with an artificial bone graft and acellular dermal matrix. As shown in this case, early and aggressive surgical debridement of the infected costal cartilage and sternum should be performed for infective costochondritis. Furthermore, delayed chest wall reconstruction could significantly contribute to the quality of life.

UNLABELLED
Infectious mononucleosis (IM), the most common presentation of acute Epstein Barr virus (EBV) infection, typically presents with fever, pharyngitis and lymphadenopathy. We describe an unusual case of IM presenting as acute sinusitis. A 25 year-old male presented to the emergency department with worsening right frontal sinus pain along with fever, chills, and greenish nasal discharge for 3 weeks. Laboratory workup showed leukocytosis with high lymphocyte counts as well as transaminitis. Facial computerized tomography (CT) showed extensive right frontal, ethmoidal and maxillary sinusitis and antrochoanal polyp. The patient underwent endoscopy with drainage of purulent material and polyp removal. Unfortunately, cultures of the sample were not sent and bacterial infection could not be ruled out. Broad spectrum antibiotics were continued. Pathology of redundant tissue revealed large atypical lymphocytes with positive EBV-encoded RNA and lack of evidence of extranodal natural killer/T-cell (NK/T-cell) type lymphoma (ENKTCL). Tests for serum EBV IgM antibodies and EBV early Antigen antibodies were positive, indicating acute EBV infection. Lymphocytosis resolved along with significant clinical improvement at the 10-day follow up visit. Even though patient did receive antibiotics, multiple factors including isolated lymphocytosis, pathology positive for EBV with no neutrophilia were more suggestive of sinusitis caused by viral infection, EBV in this case. Lymphocytosis with fever and sore throat should prompt physicians to consider IM. There are no known reports in the literature of EBV as a causal organism for acute viral sinusitis. There are some studies relating EBV with ENKTCL. It is unknown whether this particular patient with a history of EBV sinusitis will be at high risk for nasal type lymphoma in the future. Further studies should be conducted to understand the pathogenesis and relationship between EBV and ENKTCL.
LEARNING POINTS
Infectious mononucleosis (IM) can present with various atypical presentations. Consideration of IM should not be limited to people presenting with a triad of fever, lymphadenopathy and sore throat. Lymphocytosis with atypical symptoms should raise suspicion of infectious mononucleosis.No case has been reported of EBV as a causal organism for acute sinusitis. Association with EBV infection and chronic sinusitis or nasal polyp or extranodal NK/T cell lymphoma has been demonstrated but pathogenesis is poorly understood.Studies should be done on whether acute sinusitis secondary to EBV poses a risk for nasal type lymphoma.

We report a case of primary bilateral tuberculous otitis media in a patient who underwent kidney transplantation. This case presents unusual clinical features and histopathology from those of classical tuberculous otitis media. A 75-year-old woman presented at the clinic with purulent ear discharge and hearing loss in both ears. She had undergone kidney transplantation 6 years prior and had been taking immunosuppressant medications. Otoscopic examination and imaging studies suggested acute otitis media, which was irresponsive to antibiotics. The patient underwent surgery to eradicate the disease, and histopathologic examination revealed multifocal granulomas with Langhans giant cells without caseous changes. Ziehl-Neelsen staining and polymerase chain reaction confirmed the diagnosis of tuberculous otitis media. While tuberculous otitis media is a very rare manifestation of extrapulmonary tuberculosis, this case is more noteworthy in that it occurred as a primary infection rather than as a reactivation of a prior infection. In addition, it did not show the classical triad of clinical manifestations, which occurred bilaterally, and its histopathology was different from those of classical tuberculous otitis media. This case presents a new clinical variation in tuberculous otitis media.

The incidence of sebaceous carcinoma (SC) in the outer one-third of the external auditory canal is considered extremely rare, and only eight case reports have been published. We present a case of a male patient in his late 70s known case of hypertension on indapamide. His medical history included a postspinal tumour that had been treated with surgery and radiation more than 40 years ago and current complaints of right ear pain and purulent discharge. A right ear soft granular tissue mass was found. Complete debulking of the right ear mass was done in conjunction with middle ear exploration, moderately differentiated SC diagnosis was made based on the histopathological analysis. The patient was free of recurrence but then died of an unrelated pulmonary infection. SC should be suspected in elderly patients who present with long-term complaints of a mass with or without otalgia, and these patients should be examined for the presence of such tumours especially if they report a history of radiation. Additionally, more research is warranted to investigate the association of diuretics with SC.

INTRODUCTION
Gonorrhea, caused by Neisseria gonorrhoeae (NG), is the second most common bacterial sexually transmitted infection (STI). Rates of antimicrobial resistance to standard care are increasing worldwide, with many antibiotic classes now ineffective against NG. Gepotidacin is a first-in-class, bactericidal, triazaacenaphthylene antibiotic that inhibits bacterial DNA replication by inhibition of two enzymes, where a single target-specific mutation does not significantly impact susceptibility. Gepotidacin confers activity against NG, including most strains resistant to marketed antibiotics. Here, we describe the design of a phase 3 clinical trial (EAGLE-1; NCT04010539) evaluating gepotidacin for the treatment of uncomplicated urogenital gonorrhea.
METHODS
This phase 3, randomized, multicenter, sponsor-blinded, noninferiority study across six countries is comparing the efficacy of gepotidacin with ceftriaxone plus azithromycin in 400 patients with uncomplicated urogenital gonorrhea (microbiological intent-to-treat population) and assessing the safety of gepotidacin in approximately 600 patients (intent-to-treat population). Eligible participants 12 years of age or older with clinical suspicion of urogenital gonococcal infection and a NG-positive urogenital sample and/or purulent discharge are randomized 1:1 to receive oral gepotidacin (2 × 3000 mg 10-12 h apart) or ceftriaxone (500 mg, intramuscular) plus azithromycin (1 g, oral). The primary endpoint is culture-confirmed bacterial eradication of NG from the urogenital site at the test-of-cure (days 4-8) visit.
PLANNED OUTCOMES
This trial was designed in accordance with US Food and Drug Administration (2015) and European Medicines Agency (2011) guidance, particularly the primary endpoint and microbiological evaluability requirements. This study will help characterize the risk-benefit profile of gepotidacin for treating uncomplicated urogenital gonorrhea. Gepotidacin is an important potential treatment for gonorrhea to help address the urgent unmet need of multidrug resistance and the increasingly limited number of oral treatment options.

OBJECTIVES
The aim of the present study was to report clinical findings, surgical complications and outcomes for previously hoarded cats treated surgically for otitis media-interna (OMI) and to investigate the risk factors for complications and poor outcomes.
METHODS
A retrospective study was conducted of 58 cats from an institutional hoarding environment that underwent ventral bulla osteotomy (VBO).
RESULTS
Inappetence was uncommon at presentation (9/58, 16%) compared with pruritus/alopecia (50%), nasopharyngeal signs (45%), otitis externa (OE) (79%) and otitis interna (OI) (ataxia ± head tilt/head excursions) in 40%. Purulent aural discharge occurred in 36% and polyps in 26%. The tympanic bulla wall was moderately or severely thickened radiographically in 38/108 (35%) ears. Cultures were positive for subspecies in 26/48 (54%) cats. Of the 58 cats, 40 (69%) had complications after the first VBO and 19/30 (63%) after the second. Of 101 complications, 56 (55%), from 27/88 (31%) surgeries, were considered serious, including life-threatening perioperative complications in seven, OI in eight, prolonged anorexia in six and worsening of pruritus/alopecia in nine cases. Three cats developed xerostomia (dry mouth) after the second VBO. Pruritus/alopecia, nasopharyngeal signs, OE and purulent aural discharge resolved in a statistically significant proportion of cats but persisted in some. Full resolution of OI was uncommon. OI preoperatively, and surgery performed by a generalist (vs specialist) surgeon, were risk factors for OE at recheck (OI: odds ratio [OR] 4.35; 95% confidence interval [CI] 1.21-15.70; = 0.02; surgery: OR 3.64; 95% CI 1.03-12.87; = 0.045). No other prognostic indicators were identified. No variables tested were significantly associated with risk of serious complications or euthanasia.
CONCLUSIONS AND RELEVANCE
Surgical management of chronic OMI was successful in most cases but was not benign and not always beneficial. The analysis was unable to identify clinically helpful outcome predictors. Optimal management of chronic feline OMI remains a challenge, particularly for animal shelters. Less invasive approaches and chronic medical management require further investigation.

BACKGROUND
Pyomyositis generally occurs in otherwise healthy young men. Because this condition is unusual among otherwise healthy women in temperate climates, we present the following case.
CASE SUMMARY
An otherwise healthy 43-year-old woman presented with bilateral pain in her lower extremities and fever. Magnetic resonance imaging (MRI) findings were indicative of myositis with a possible abscess. We initiated empirical antibiotic therapy with ceftriaxone. However, the swelling and pain in her legs persisted even after 7 d of treatment. Contrast MRI revealed multiple pockets of pus in the vastus lateralis and gluteal muscles. We performed needle aspiration of these abscesses with ultrasound guidance and local anesthesia. Upon culturing, the purulent material was positive for . We diagnosed her with -induced pyomyositis of the vastus lateralis muscle and gluteus region. Based on the antibiotic sensitivity report, ceftriaxone was administered for an additional 7 d. By day 15 post-drainage, the patient was able to start walking. Oral antibiotic therapy was continued for 1 wk following her discharge from hospital, after which her symptoms resolved completely.
CONCLUSION
Pyomyositis may present with muscle pain, swelling, and fever. Ultrasound-guided percutaneous puncture and drainage may enable timely diagnosis and treatment.

Irish Veterinary Journal Sep 2023To the best of our knowledge, this is the first report of female genital system infiltration of T-cell lymphoma in veterinary literature.
BACKGROUND
To the best of our knowledge, this is the first report of female genital system infiltration of T-cell lymphoma in veterinary literature.
CASE PRESENTATION
A 1.5-year-old, intact female Golden Retriever was referred due to melena and hyporexia that lasted for three weeks. Fever (40.5℃), tachycardia, tachypnoea, pale mucous membranes, and purulent vaginal discharge were identified on physical examination. Blood analyses revealed leucocytosis, anaemia, hypoalbuminemia, and increased lactate and C-reactive protein levels. On abdominal radiography, the small intestine was moderately deviated because of an oval-shaped mass (13 cm × 8.7 cm) located in the mid-abdomen. An enlarged tubular-shaped structure that had the opacity of soft tissue located in dorsal to the bladder to the middle of the abdomen, and an oval-shaped mass (5.28 cm × 3.26 cm), which was suspected to be a medial iliac lymph node located at the sixth to seventh lumbar level. Abdominal ultrasonography revealed gas and fluid in the lumen of the uterine horn with a severely thickened wall, round enlarged lymph nodes around the genitourinary system, and free fluid in the abdominal cavity. Based on these results, pyometra was suspected, and an exploratory laparotomy was performed for ovariohysterectomy. The resected ovary and uterus were macroscopically hypertrophied. Histopathological examination of the ovary and uterus revealed neoplastic proliferation of large round cells with strong immunoreactivity for CD3, indicating T-cell lymphoma. Therefore, the young dog was diagnosed with genital lymphoma.
CONCLUSIONS
The present report describes T-cell lymphoma infiltrating the uterus and ovaries in a young dog, which is rarely diagnosed and could aid in the differential diagnosis of genital diseases in young dogs.
