The patient, a male newborn, was admitted to the hospital 2 hours after birth due to prematurity (gestational age 27 weeks) and respiratory distress occurring 2 hours postnatally. After admission, the infant developed fever and elevated C-reactive protein levels. On the fourth day after birth, metagenomic next-generation sequencing of cerebrospinal fluid indicated a positive result for (9 898 reads). On the eighth day, a retest of cerebrospinal fluid metagenomics confirmed (56 806 reads). The diagnosis of purulent meningitis caused by was established, and the antibiotic treatment was switched to moxifloxacin [5 mg/(kg·day)] administered intravenously for a total of 4 weeks. After treatment, the patient's cerebrospinal fluid tests returned to normal, and he was discharged as cured on the 76th day after birth. This article focuses on the diagnosis and treatment of neonatal purulent meningitis, introducing the multidisciplinary diagnosis and treatment of the condition in extremely preterm infants.

BACKGROUND
Postpartum uterine disease (metritis) is common in dairy cows. The disease develops within 1 week after calving and is associated with microbial dysbiosis, fever, and fetid uterine discharge. Cows with metritis have a greater likelihood of developing endometritis and infertility later postpartum. Antibiotic treatment is used to relieve symptoms of metritis but the capacity of antibiotic treatment to improve fertility later postpartum is inconsistent across published studies. We hypothesized that an antibiotic has only a short-term effect on the uterine microbiome and does not change the progression of disease from metritis to endometritis. To test this hypothesis, we studied the effects of systemic antibiotic given to cows diagnosed with metritis and healthy cows early postpartum on the development of endometritis and the uterine microbiome at 1 month postpartum.
RESULTS
Cows diagnosed with metritis were compared to healthy ones in a 2 × 2 factorial design, where they were either treated with an antibiotic (ceftiofur hydrochloride) at 7 to 10 days postpartum or left untreated. Cows were slaughtered at one month postpartum and the uterus was assessed for endometritis (presence of purulent material in the uterine lumen and inflammation in the endometrium) and uterine samples were collected for bacteriology and metagenomics (16S rRNA gene sequencing). As expected, the uterine microbiome at disease diagnosis had dysbiosis of typical metritis pathogens (e.g., Fusobacterium, Bacteroides, and Porphyromonas) in diseased compared with healthy cows. At one month postpartum, there was a tendency for more endometritis in metritis cows compared with healthy but antibiotic treatment had no effect on endometritis prevalence regardless of the original disease diagnosis. Likewise, when bacteria were cultured or sequenced, there were a greater number of species (culture) or amplicon sequence variants (ASV; sequencing) in the uterine lumen of cows with metritis. However, antibiotic treatment had no effect on the prevalence of cultured species or the composition of the detected ASV. The uterine microbiome at 1 month postpartum was associated with the clinical observation of the uterus (endometritis or healthy).
CONCLUSIONS
Early postpartum antibiotic treatment only provides temporary resolution of uterine dysbiosis that is not sustained long-term. Failure to resolve the dysbiosis is associated with a greater prevalence of endometritis in cows with metritis, and the occurrence of endometritis significantly impacts fertility later postpartum.

International Journal of Surgery Case... May 2024Oesophageal fistula is a severe complication that may occasionally develop after chemoradiotherapy (CRT) for oesophageal cancer and is difficult to treat.
INTRODUCTION AND IMPORTANCE
Oesophageal fistula is a severe complication that may occasionally develop after chemoradiotherapy (CRT) for oesophageal cancer and is difficult to treat.
CASE PRESENTATION
A 51-year-old man who had undergone CRT for oesophageal cancer presented with haematemesis and was diagnosed with a descending aortic aneurysm and an oesophageal fistula. Thoracic endovascular aneurysm repair was performed to achieve haemostasis. After 3 days, the patient underwent subtotal oesophagectomy and cervical oesophagostomy with delivery of a pedicled omental flap to the exposed aortic stent. Six months later, ileocecal reconstruction was performed. The second patient was a 49-year-old woman who had undergone CRT 1 year previously. She complained of leg weakness and gait disorder. After a workup, she was diagnosed with perforation of the posterior wall of the cervical oesophagus with abscess formation and purulent spondylitis. After two spinal fusion surgeries, we performed tracheotomy and drained the cervical region to reduce local infection. After 7 days, she underwent pharyngolaryngoesophagectomy and reconstruction using a gastric conduit, to which a large section of the omental flap was attached. After the multi-stage surgery, oral intake became possible, and both patients were discharged.
CLINICAL DISCUSSION
The optimal treatment strategy for post-CRT oesophageal fistula remains controversial. Radical surgery, including oesophagectomy, is the treatment of choice, although it is associated with high mortality rates. Multi-stage surgery may be useful for reducing surgical stress in moribund patients.
CONCLUSION
We reported two cases involving radiation-induced oesophageal fistula successfully treated by multi-stage surgery without major complications.

Herd-level associations between the proportion of elevated prepartum nonesterified fatty acid concentrations and postpartum diseases, reproduction, or culling on dairy farms.
The objectives of this herd-level prospective observational cohort study were to describe the proportion of cows with elevated prepartum nonesterified fatty acid concentrations (PropElevNEFA) in dairy herds and to assess the herd-level associations between PropElevNEFA and postpartum diseases, reproductive performance, and culling. From November 2018 to December 2020, a convenience sample of 49 herds was enrolled in this study. Blood sampling (16 to 29 cows per herd) was performed during the week before and during the 2 wk following calving to quantify the concentration of nonesterified fatty acids (NEFA) and β-hydroxybutyrate acids (BHBA), respectively. Elevated NEFA was defined as ≥280 µmol/L and hyperketonemia as BHBA ≥1.4 mmol/L. Retained placenta, metritis, purulent vaginal discharge, endometritis, and mastitis were diagnosed on-farm following standardized definitions, and success at first artificial insemination (AI) and culling events were recorded. The associations between PropElevNEFA and each individual disease, success at first AI, and culling were evaluated using Bayesian aggregated binomial regression models with weakly informative priors, from the which odds ratio (OR) and the 95% credible intervals (BCI) were obtained. A total of 981 cows were included in the statistical analyses representing 16 to 29 (median = 19) cows per herd. Cows were enrolled in the prepartum period of their first to tenth (median = third) lactation, and 41% of them had an elevated prepartum NEFA concentration. At the herd level, PropElevNEFA varied between 11% and 78% (median = 39%). The odds of metritis (OR = 1.37, 95% BCI = 1.13-1.67) increased for every 10-point increase in PropElevNEFA, whereas the odds of success at first AI decreased (OR = 0.69, 95% BCI = 0.59-0.80). The PropElevNEFA was not associated with the other tested diseases or culling. Our results suggest that the herd-level proportion of cows having elevated prepartum NEFA concentrations is associated with metritis and poor success at first AI in dairy herds.

Prosthetic joint infection (PJI) remains a significant complication following joint arthroplasty, necessitating prompt recognition and intervention to optimize patient outcomes. This case report describes a 65-year-old male who presented with persistent pain, swelling, and purulent discharge from the right hip, three years post-bipolar hemiarthroplasty following a road traffic accident. Clinical examination revealed signs suggestive of PJI, prompting surgical intervention with total hip arthroplasty. Postoperatively, the patient experienced resolution of symptoms and satisfactory recovery. This case underscores the challenges associated with infected joint arthroplasty and highlights the importance of a multidisciplinary approach for effective management. Early diagnosis, appropriate surgical intervention, and comprehensive postoperative care are essential for minimizing morbidity associated with PJIs and optimizing patient outcomes.

Medication-related osteonecrosis of the jaw (MRONJ) poses a challenging form of osteomyelitis in patients undergoing antiresorptive therapies in contrast to conventional osteomyelitis. This study aimed to compare the clinical and radiological features of MRONJ between patients receiving low-dose medications for osteoporosis and those receiving high-dose medications for oncologic purposes. The clinical, panoramic radiographic, and computed tomography data of 159 patients with MRONJ (osteoporotic group, n = 120; oncologic group, n = 39) who developed the condition after using antiresorptive medications for the management of osteoporosis or bone malignancy were analyzed. The osteoporotic group was older (75.8 vs. 60.4 years, p < 0.01) and had a longer duration of medication usage than the oncologic group (58.1 vs. 28.0 months, p < 0.01). Pus discharge and swelling were more common in the osteoporotic group (p < 0.05), whereas bone exposure was more frequent in the oncologic group (p < 0.01). The mandibular cortical index (MCI) in panoramic radiographs was higher in the osteoporotic group (p < 0.01). The mean sequestra size was larger in the oncologic group than in the osteoporotic group (15.3 vs. 10.6 mm, p < 0.05). The cured rate was significantly higher in the osteoporotic group (66.3% vs. 33.3%, p < 0.01). Oncologic MRONJ exhibited distinct clinical findings including rapid disease onset, fewer purulent signs, and lower cure rates than osteoporotic MRONJ. Radiological features such as sequestrum size on CT scan, and MCI values on panoramic radiographs, may aid in differentiating MRONJ in osteoporotic and oncologic patients.

Complications can arise secondary to anorectal suppurative diseases, with infections spreading along the extraperitoneal space, such as the peri-vesical, prevesical, pre-sacral, and pararectal spaces, resulting in abscesses at remote sites, which can make diagnosis more challenging. Due to the absence of peritonitis symptoms, there is a delay in presentation among such patients. Comprehending the intricacies of these areas and the way infection can spread within them is crucial for promptly identifying and effectively draining the extraperitoneal abscess. We present a case series of six patients with a mean age of 45, all males. A total of three patients had undergone incision and drainage after being diagnosed with anorectal suppurative disease and remained symptomatic after the initial surgical intervention of incision and drainage. Two patients initially diagnosed with anterior abdominal abscesses patients, after being treated with incision and drainage, continued to have purulent discharge from the drainage site. Finally, the last patient continued to present with perianal pain after an open hemorrhoidectomy. CT scans of all six patients showed collections in the extraperitoneal spaces correlated with the observed complications. To deepen our understanding of pelvic extraperitoneal spaces, cadaver dissections were conducted and compared with CT images. Through cadaver dissections and CT imaging, the study provides insights into the anatomy and interconnections of pelvic extraperitoneal spaces, emphasizing the importance of early CT scans for diagnosis. Understanding these intricate anatomical structures is essential for accurate diagnosis and efficient and effective treatment. Timely diagnosis is vital to prevent prolonged illness and reduce the risk of complications and mortality. The importance of early CT scans in suspected patients is underscored, which is highly important to expedite appropriate actions.

INTRODUCTION AND IMPORTANCE
Cutaneous Tuberculosis (CTB), elicited by the Mycobacterium tuberculosis complex, manifests dermatologically. The scarcity of bacilli within CTB lesions renders their detection challenging. This study presents a case of CTB, underscoring its rarity and the potential for severe complications that can deteriorate patient quality of life. It aims to highlight the importance of CTB identification in dermatological diagnoses due to its capacity to cause considerable morbidity and affect patients' psychosocial health.
CASE PRESENTATION
An 18-year-old patient presented with a painful, well-defined reddish plaque on the right palm, originating five years prior, accompanied by contractures of the middle finger. The tender lesion, characterized by an irregular surface, exhibited purulent discharge upon light touch through fissures along its periphery. Management involved necrotomy, debridement, and tissue biopsy for diagnostic and reconstructive purposes.
CLINICAL DISCUSSION
CTB exhibits a wide range of clinical presentations, often resembling other dermatological infections, which complicates its diagnosis. Accurate diagnosis necessitates an integrated approach involving clinical assessment, the tuberculin skin test, histopathological analysis, and bacteriological investigations. The therapeutic regimen includes multidrug anti-tuberculosis treatment, with surgical intervention reserved for specific cases.
CONCLUSION
Long-term complications of untreated CTB encompass significant contractures, scarring, and the onset of carcinomas and sarcomas. Prompt diagnosis facilitates timely and effective treatment, averting these sequelae and yielding high patient satisfaction.

INTRODUCTION
Bartholin's gland abscesses are rare in pediatric patients, with limited documented cases. This case report aims to contribute valuable insights into managing this uncommon condition in children.
METHODS
A thorough examination and diagnostic workup were conducted on a 4-month-old female infant presenting with labial swelling. Clinical assessment strongly suggested the presence of a Bartholin's gland abscess. A culture of purulent discharge revealed the presence of and Gram-negative . Antibiotic susceptibility testing guided the choice of treatment. . Despite initial treatment with oral antibiotics and sitz baths, there was limited therapeutic response. Close surveillance under the guidance of a pediatric surgeon continued for two months. Subsequently, surgical excision of the Bartholin gland was performed, and the specimen was sent for pathological examination.
RESULTS
Pathological analysis revealed signs of ulceration and granulation tissue, indicative of a mixed inflammatory response. An eight-month follow-up demonstrated marked improvement and overall well-being in the patient.
CONCLUSION
This case report underscores the importance of considering Bartholin's gland abscess in diagnosing labial swelling in pediatric patients. The successful outcome achieved through surgical excision and appropriate antibiotic therapy provides valuable insights for potential treatment approaches in similar cases. Continued research and comprehensive studies are essential for establishing optimal treatment protocols for this patient demographic.

: Transcutaneous osseointegration following amputation (TOFA) confers better mobility and quality of life for most patients versus socket prosthesis rehabilitation. Peri-TOFA infection remains the most frequent complication and lacks an evidence-based diagnostic algorithm. This study's objective was to investigate preoperative factors associated with positive intraoperative cultures among patients suspected of having peri-TOFA infection in order to create an evidence-based diagnostic algorithm. : We conducted a retrospective study of 83 surgeries (70 patients) performed to manage suspected lower-extremity peri-TOFA infection at a specialty orthopedic practice and tertiary referral hospital in a major urban center. The diagnosis of infection was defined as positive intraoperative cultures. Preoperative patient history (fevers, subjective pain, increased drainage), physician examination findings (local cellulitis, purulent discharge, implant looseness), and laboratory data (white blood cell count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and external swab culture) were evaluated for association with subsequent positive intraoperative cultures using regression and area under receiver-operator curve (AUC) modeling. : Peri-implant limb pain (highly correlated with infection), ESR (highly correlated against infection), positive preoperative swab (moderately correlated with infection), gross implant motion (moderately correlated against infection), and erythema or cellulitis of the transcutaneous region (mildly correlated with infection) were variables included in the best AUC model, which achieved an 85 % positive predictive value. Other clinical findings and laboratory values (notably CRP and WBC) were non-predictive of infection. : This seminal investigation to develop a preoperative diagnostic algorithm for peri-TOFA infection suggests that the clinical examination remains paramount. Further evaluation of a wider spectrum of clinical, laboratory, and imaging data, consistently and routinely collected with prospective data techniques in larger cohorts of patients, is necessary to create a robust predictive algorithm.
