Analysis of virulence profiles in clinical isolates of Klebsiella pneumoniae from renal abscesses: clinical significance of hypervirulent isolates.

Introduction: Klebsiella pneumoniae can cause a wide range of infections. Hypervirulent K. pneumoniae (hvKp), particularly associated with the K1 and K2 capsular types, is an increasingly significant microorganism with the potential to cause invasive infections, including renal abscesses. Despite the rising prevalence of hvKp infections, information on renal abscesses caused by K. pneumoniae is limited, and the clinical significance of hvKp associated with specific virulence genes remains elusive. Methods: This study performed at a 1200-bed tertiary hospital sought to identify the clinical and microbiological characteristics of renal abscesses caused by K. pneumoniae, focusing on various virulence genes, including capsular serotypes and multilocus sequence typing (MLST). Results: Over an 8-year period, 64 patients with suspected renal abscesses were reviewed. Ten patients diagnosed with K. pneumoniae-related renal abscesses were ultimately enrolled in the study. Among the isolates from the 10 patients, capsular serotype K2 was predominant (40.0%), followed by K1 (30.0%). The most common sequence type by MLST was 23 (40.0%). In particular, six patients (60.0%) harbored specific genes indicative of hvKp: iucA, peg-344, rmpA, and rmpA2. Conclusions: Our findings highlight the importance of hvKp as a pathogen in renal abscesses. Although the nature of hvKp is relatively unknown, it is widely recognized as a highly virulent pathogen that can infect relatively healthy individuals of various ages and simultaneously cause infections at multiple anatomical sites. Therefore, when treating patients with K. pneumoniae-related renal abscesses, caution is necessary when considering the characteristics of hvKp, such as potential bacteremia, multi-organ abscess formation, and metastatic spread.

Conventional herniorrhaphy followed by laparoscopic appendectomy for a variant of Amyand's hernia: a case report.

BACKGROUND: Amyand's hernia (AH) is an appendix (with or without acute inflammation) trapped within an inguinal hernia. Most AH with acute appendicitis had a preexisting appendix within the hernia sac. We herein report a variant of AH that has never been described before. An inflamed appendix that was managed conservatively was found to have migrated and trapped in the sac of a previously unrecognized right inguinal hernia 6 weeks after the index admission, resulting in a secondary Amyand's hernia. CASE PRESENTATION: A 25-year-old healthy Taiwanese woman had persistent right lower abdominal pain for 1 week and was diagnosed with perforated appendicitis with a localized abscess by abdominal computed tomography (CT). No inguinal hernia was noted at that time. Although the inflamed appendix along with the abscess was deeply surrounded by bowel loops so that percutaneous drainage was not feasible, it was treated successfully with antibiotics. However, she was rehospitalized 6 weeks later for having a painful right inguinal bulging mass for a week. Abdominal CT revealed an inflamed appendix with abscess formation in an indirect inguinal hernia raising the question of a Amyand's hernia with a perforated appendicitis. Via a typical inguinal herniorrhaphy incision, surgical exploration confirmed the diagnosis, and it was managed by opening the hernial sac to drain the abscess and reducing the appendix into the peritoneal cavity, followed by conventional tissue-based herniorrhaphy and a laparoscopic appendectomy. She was then discharged uneventfully and remained well for 11 months. CONCLUSIONS: Unlike the traditional definition of Amyand's hernia, where the appendix is initially in the hernia sac, the current case demonstrated that Amyand's hernia could be a type of delayed presentation following initial medical treatment of acute appendicitis. However, it can still be managed successfully by a conventional tissue-based herniorrhaphy followed by laparoscopic appendectomy.

[A Case of Bacterial Meningitis in Which Occurrence of Ataxie Optique Led to Detection of a Small Subdural Abscess and Pialitis].

We report the case of a 69-year-old man with bacterial meningitis who presented with ataxie optique in the peripheral part of the left visual field in both hands. A detailed neurological examination with contrast-enhanced brain MRI in the early stage of the clinical course identified a small subdural abscess and pialitis in the right parietal area. A favorable outcome was obtained with antibiotic therapy alone. In a case with higher brain dysfunction of unknown cause in the clinical course of bacterial meningitis, a detailed neurological examination may be helpful to identify the causative site.

Analysis of risk factors leading to multiple breast abscesses during lactation.

We investigated 1805 cases of breast abscesses during lactation to estimate the risk factors for multiple breast abscesses during lactation. A total of 2000 cases of breast abscesses during lactation were investigated using an online questionnaire, and 1805 cases with complete data were analyzed. The survey response rate was 90%. According to the number of abscesses, the patients were divided into 2 groups: single breast abscess (number = 1298) and multiple breast abscess (number = 507). Pearson chi-square test was used to compare the 15 risk factors between the 2 groups. Risk factors with significant differences were substituted into a binary logistic regression model to analyze the independent risk factors associated with multiple breast abscesses during lactation. There were significant differences between the 2 groups in (1) weeks postpartum, (2) separated from the baby, (3) breastfeeding exclusivity, (4) nipple inversion, (5) fever, (6) breast redness/swelling, (7) nipple pain, (8) breast massage by nonmedical staff, with (1), (5), (6), and (8) being independent risk factors. Patients under 6 weeks postpartum, separated from the baby, not exclusively breastfeeding, having an inverted nipple on the affected side, fever, breast skin redness and swelling on the affected side, nipple pain, and having undergone a breast massage by nonmedical staff are more likely to develop multiple breast abscesses.

Disseminated Tuberculosis Revealed by Conus Medullaris Tuberculoma.

A 29-year-old man from Comoros presented with rapidly progressive paraplegia and sexual dysfunction. Magnetic resonance imaging (MRI) showed a contrast-enhanced conus medullaris lesion. Differential diagnoses included tumors, abscesses, and inflammatory diseases. Neurosurgery was delayed to complete examinations. Cerebral MRI showed three abscesses. Body computed tomography scan showed supracentimetric polyadenopathies, pulmonary nodules, prostatic lesion, and enhanced seminal vesicle, with hypermetabolism on positron emission tomography with 2-deoxy-2-[fluorine-18]fluoro-D-glucose scan. Histology of lymph node biopsy showed granulomatous infiltration without acid-fast bacilli, and positive polymerase chain reaction for Mycobacterium tuberculosis. Lymph node culture was positive after 2 months, urine culture after 3 weeks, but cerebrospinal fluid and sputum cultures were negative. A 1-year antituberculosis therapy was initiated, associated with corticosteroids because the patient developed tuberculosis-immune reconstitution syndrome, revealed by the recurrence of neurological symptoms. After 2 months the patient completely recovered and could run. MRI showed stability of the voluminous tuberculoma with decrease of medullary edema. Avoiding surgery in those cases may prevent iatrogenic neurological deterioration.

Perirectal Abscess with Anterior Extension to the Extraperitoneum and Space of Retzius: A Case Report.

Introduction-This report illuminates the distinctive features of a successfully managed Retzius space infection arising from a complex perirectal abscess. It adds novel insights to the scientific literature by addressing the rarity of such occurrences, highlighting the diagnostic complexities associated with extraperitoneal spread, and underscoring the crucial role of a nuanced understanding of anatomy in navigating clinical scenarios involving anorectal abscesses. Patient's Main Concerns and Important Clinical Findings-A 68-year-old male presented with dizziness and diffuse lower abdominal pain, accompanied by intermittent perianal pain for one month. Regardless of an initial misdiagnosis as hemorrhoids, the patient presented sepsis status with fever, hypotension, and tachycardia upon admission. Clinical examinations, including a digital rectal examination, laboratory findings, and imaging studies, revealed a substantial perianal abscess extending into the space of Retzius. Primary Diagnoses, Interventions, and Outcomes-The primary diagnosis involved a heterogeneous fluid-filled perianal abscess extending into the Retzius space, confirmed by abdominal contrast-enhanced computed tomography (CT). Immediate initiation of broad-spectrum antibiotics and subsequent incision and drainage in the 8 o'clock region was performed. Post-operatively, the patient experienced rectal bleeding, necessitating suturing ligation. A follow-up CT scan revealed an extraperitoneal abscess around the bladder, leading to CT-guided drainage and identification of microbial pathogens. Antibiotic treatment with piperacillin-tazobactam was administered. With two weeks of antibiotics and post-operative care, the patient's symptoms improved, and he was discharged with no signs of recurrence or complications. Conclusions-This case report emphasizes the importance of early consideration and identification of extraperitoneal abscesses for timely intervention. The complexity of anatomical planes in extraperitoneal spaces poses diagnostic challenges, necessitating a strategic treatment. The successful management of this case underscores the significance of a multidisciplinary approach, including prompt diagnosis, appropriate antibiotic therapy, and timely surgical interventions, ultimately contributing to improved outcomes in cases involving complex anorectal abscesses.

Ethanol endometrioma sclerotherapy: safety through 8 years of experience.

STUDY QUESTION: What are the complications of transvaginal ethanol sclerotherapy for the treatment of endometriomas? SUMMARY ANSWER: Sclerotherapy is a reliable, minimally invasive method applicable in outpatient procedures but with specific and potential life-threatening complications that need to be identified and prevented. WHAT IS KNOWN ALREADY: There are currently few data on the use of transvaginal ethanol sclerotherapy, and we mainly note septic complications. STUDY DESIGN, SIZE, DURATION: A retrospective observational cohort study was carried out. The study was conducted at an academic hospital and included 126 women aged 31.9 ± 5.5 years (mean ± SD), between November 2013 and June 2021. We analyzed a total of 157 ethanol sclerotherapy treatment (EST), treated by 131 EST procedures, in 126 women. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included women with an indication for transvaginal ethanol sclerotherapy. Indications were women with at least one endometrioma over 10 mm, isolated or associated with other endometriosis locations, requiring treatment for pain or infertility before assisted reproductive treatment. We followed a standardized transvaginal ethanol sclerotherapy procedure consisting of an ultrasound-guided transvaginal puncture of one or more endometriomas under general anesthesia. The cyst content was completely removed and flushed with saline solution. Ethanol (96%) was injected at 60% of the initial volume of the endometrioma, remained in the cyst for 10 min and was then completely removed. Ethanol loss was defined as a loss of 5 ml or more than 10% of the initial volume of the injected ethanol. Failure was defined by the contraindication of endometrioma puncture because of interposition of the digestive tract, ethanol loss in the previous endometrioma treated (in case of multiple ESTs), failure to aspirate the endometriotic fluid, contraindication to start ethanol injection owing to saline solution leakage, or contraindication to continue ethanol injection owing to suspicions of ethanol leakage at sonography. Intraoperative complications were defined by ethanol loss, positive blood alcohol level, and ethanol intoxication. Postoperative complications were defined by fever, biological inflammatory syndrome, and ovarian abscess. Complications were classified according to the Clavien and Dindo surgical classification, which is a system for classifying postoperative complications in five grades of increasing severity. MAIN RESULTS AND THE ROLE OF CHANCE: We reported a total of 17/157 (10.8%) transvaginal ethanol sclerotherapy failures during 14/131 (10.7%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. In the same sets of data, complication was reported for 15/157 (9.5%) transvaginal ethanol sclerotherapy in 13/131 (9.9%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. Nine of 126 women (7.1%) had a grade I complication, one (0.8%) had a grade II complication (medical treatment for suspicion of pelvic infection), two (1.6%) had a grade III complication (ovarian abscess) and one (0.8%) had a grade IV complication (ethanol intoxication). We did not observe any grade V complications. LIMITATIONS, REASONS FOR CAUTION: This was a retrospective study and pain assessment not considered. The benefit-risk balance of endometrioma transvaginal ethanol sclerotherapy was not evaluated. WIDER IMPLICATIONS OF THE FINDINGS: Our study is the first to evaluate the complications of transvaginal ethanol sclerotherapy with such a large cohort of women in a standardized protocol. Transvaginal ethanol sclerotherapy seems to be an effective alternative to laparoscopic surgery in the management of endometriomas and limits the alteration of ovarian reserve. Transvaginal ethanol sclerotherapy is a reliable, minimally invasive method applicable on an outpatient basis. The majority of complications are Clavien-Dindo ≤IV, for which preventative measures, or at least early diagnosis and treatment, can be easily performed. The risk of ethanol intoxication is rare, but it is a life-threatening risk that must be avoided by appropriate implementation and promotion of the sclerotherapy procedures. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: Aix Marseille University's ethics committee registration number 2021-06-03-01.

High risk and low prevalence diseases: Acute mastoiditis.

INTRODUCTION: Acute mastoiditis is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE: This review highlights the pearls and pitfalls of mastoiditis, including the presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: Acute mastoiditis most commonly affects pediatric patients and is a suppurative infection of the mastoid air cells. It is often associated with otitis media, and common bacteria include Streptococcus and Staphylococcus. History and examination may reveal tympanic membrane erythema, pinna protrusion, postauricular erythema, mastoid tenderness with palpation, external canal swelling, otorrhea, fever, and malaise. The disease should be suspected in those who fail treatment for otitis media and those who demonstrate the aforementioned abnormalities on examination and systemic symptoms. Laboratory analysis may reveal evidence of systemic inflammation, but a normal white blood cell count and other inflammatory markers should not be used to exclude the diagnosis. Computed tomography (CT) of the temporal bones with intravenous contrast is the recommended imaging modality if the clinician is unsure of the diagnosis. CT may also demonstrate complications. Treatment includes antibiotics such as ampicillin-sulbactam or ceftriaxone as well as otolaryngology consultation. Complications may include subperiosteal and intracranial abscess, deep neck abscess, facial nerve palsy, meningitis/encephalitis, venous sinus thrombosis, and seizures. CONCLUSIONS: An understanding of acute mastoiditis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

[Perioperative management of wounds associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy and its clinical effects].

Objective: To investigate the perioperative management of wounds associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy, and to evaluate its clinical effects. Methods: This study was a retrospective observational study. From January 2017 to December 2022, 36 patients with wounds associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy who were conformed to the inclusion criteria were admitted to the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University, including 23 males and 13 females, aged 25 to 81 years. Preparation for surgery was made. For patients with suspected retrosternal mediastinal abscess cavity, all cancellous bone of the unhealed sternum was bitten off to fully expose the retrosternal mediastinum, remove the source of infection and granulation tissue, and to fill the sternum defect with flipped unilateral pectoralis major muscle. For patients who had no retrosternal mediastinal infection but had fresh granulation tissue in unhealed sternal wounds, the necrotic tissue and a small amount of necrotic sternum were palliatively removed, and bilateral pectoralis major muscles were advanced and abutted to cover the sternal defect. After the skin in the donor area was closed by tension-relieving suture, continuous vacuum sealing drainage was performed, and continuous even infusion and lavage were added 24 hours later. The thorax was fixed with an armor-like chest strap, the patients were guided to breathe abdominally, with both upper limbs fixed to the lateral chest wall using a surgical restraint strap. The bacterial culture results of wound exudation specimens on admission were recorded. The wound condition observed during operation, debridement method, muscle flap covering method, intraoperative bleeding volume, days of postoperative infusion and lavage, lavage solution volume and changes on each day, and postoperative complications and wound healing time were recorded. After discharge, the wound healing quality, thorax shape, and mobility functions of thorax and both upper limbs were evaluated during follow-up. The stability and closure of sternum were observed by computed tomography (CT) reexamination. Results: On admission, among 36 patients, 33 cases were positive and 3 cases were negative in bacterial culture results of wound exudation specimens. Intraoperative observation showed that 26 patients had no retrosternal mediastinal infection but had fresh granulation tissue in unhealed sternal wounds, palliative debridement was performed and bilateral pectoralis major muscles were advanced and abutted to cover the defect. In 10 patients with suspected retrosternal mediastinal abscess cavity, the local sternum was completely removed by bite and the defect was covered using flipped unilateral pectoralis major muscle. During the operation, one patient experienced an innominate vein rupture and bleeding of approximately 3 000 mL during mediastinal exploration, and the remaining patients experienced bleeding of 100-1 000 mL. Postoperative infusion and lavage were performed for 4-7 days, with a lavage solution volume of 3 500-4 500 mL/d. The lavage solution gradually changed from dark red to light red and finally clear. Except for 1 patient who had suture rupture caused by lifting the patient under the armpit during nursing on the 3rd day after surgery, the wounds of the other patients healed smoothly after surgery, and the wound healing time of all patients was 7-21 days. Follow-up for 3 to 9 months after discharge showed that the patient who had suture rupture caused by armpit lifting died due to multiple organ failure. In 1 patient, the armor-like chest strap was removed 2 weeks after surgery, and the shoulder joint movement was not restricted, resulting in local rupture of the suture, which healed after dressing change. The wounds of the remaining patients healed well, and they resumed their daily life. The local skin of patient's pectoralis major muscle defect was slightly sunken and lower than that of the contralateral thorax in the patients undergoing treatment of pectoralis major muscle inversion, while no obvious thoracic deformity was observed in patients undergoing treatment with pectoralis major muscle propulsion and abutment. The chest and upper limb movement in all patients were slightly limited or normal. CT reexamination results of 10 patients showed that the sternum was stable, the local sternum was closed or covered completely with no lacuna or defects. Conclusions: Once the wound associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy is formed, individualized and precise debridement should be performed as soon as possible, different transfer ways of pectoralis major muscle flap should be chosen to cover the defect, and postoperative continuous infusion and lavage together with strict thorax and shoulder joint restraint and immobilization should be performed. This treatment strategy can ensure good wound healing without affecting the shape and function of the donor area.

A Rare Case of Retroperitoneal Abscess Caused by Nephro-Colic Fistula Resulting from Staghorn Calculus.

BACKGROUND Nephro-colic fistulas are uncommon, generally caused by local inflammation, trauma, or neoplasia affecting the kidney or the colon. Their association with a coralliform stone is described in a few case reports, but their management is difficult and differs quite a lot, depending on the clinical situation. We report an atypical clinical case of a reno-colic fistula associated with a staghorn calculus. This case adds to the literature an iconography rarely found. CASE REPORT A 68-year-old woman presented to the Emergency Department with respiratory symptoms and chronic abdominal pain. The biological results showed a high inflammatory syndrome. The radiological assessment revealed a retroperitoneal and left retro-renal abscess, attributed to a left nephro-colic fistula associated with the partial passage of a lithiasis within the colonic lumen. Colonoscopy confirmed the diagnosis. Multiple recurrences of diverticulitis in this region could be the origin of the complication. First, the patient was treated with antibiotic therapy and radiological drainage. Second, she benefited from a left nephrectomy, left segmental colectomy, and splenectomy. The clinical and radiological evolution were favorable after surgery. The follow-up was disrupted by hospitalizations in the Cardiology Department for cardiac decompensation. CONCLUSIONS Kidney stones along with local inflammatory phenomena can be the cause of a nephro-colic fistula. Due to the lack of guidelines in such cases, their diagnosis and management are difficult to ascertain. Surgery is the right course of treatment.

Recurrent Idiopathic Granulomatous Mastitis: A Case Report.

Idiopathic granulomatous mastitis is a rare benign breast disease of unknown aetiology mostly presenting as a breast abscess but not responding to usual conservative management with incision and drainage and frequently mimics breast cancer. We present a case 31-year-old female presented with complaints of right breast pain and redness who was initially diagnosed and treated as a case of breast abscess with repeated incision and drainage and antibiotics but did not improve. Later histopathology revealed granuloma with giant cell reaction and the patient was given a trial of steroids which showed no improvement. Wide local excision with a long course of broad-spectrum antibiotics was performed which led into remission. This case report highlights the importance of considering idiopathic granulomatous mastitis as differentials in non-responding breast abscesses. Histopathology for diagnosis and trial of wide local excision with a long course of broad-spectrum antibiotics as treatment may be done for management. Keywords: antibiotics; case reports; granuloma; mastitis.

Primary Orbital Tuberculosis with Cold Abscess: A Case Report.

Orbital tuberculosis is a rare form of extrapulmonary tuberculosis involving orbital soft tissue, periosteum, bones and lacrimal glands. This is a case report of a 6-year-old male child who presented with swelling of the right upper eyelid. He had normal visual acuity without signs of diplopia or ophthalmoplegia. The tuberculin skin test was reactive and the computed tomography scan showed peripherally enhancing collection with bony erosion and intracranial extension in the extraconal space of the superolateral right orbit. Orbital exploration was done which showed caseous material. The histological examination revealed necrotizing granulomatous tissue. The caseous material on Ziehl Neelsen staining confirmed acid-fast bacilli causing a tubercular abscess. The child is currently on anti-tubercular therapy planned for 12 months. Orbital tuberculosis might or might not be in association with pulmonary tuberculosis and should always be taken into consideration while dealing with chronic inflammatory orbital disease and an orbital mass. Keywords: case reports; orbit; tuberculosis.

Orbital Abscess Secondary to Nasolacrimal Duct Obstruction in an Extremely Preterm Infant.

Orbital abscesses are rarely encountered in children younger than 1 year. The literature is limited to isolated case reports and a few case series. Most such cases are reported in infants born at term, with the earliest reported gestational birth age at 34 weeks. Children are more prone to orbital cellulitis compared with adults due to their underdeveloped sinuses and immature immune systems, and the origin is most commonly an ethmoid sinus infection. Orbital cellulitis secondary to dacryocystitis is even less common, with only a few isolated cases reported in infants and children. Herein, the authors present a case of a large extraconal and intraconal orbital abscess secondary to nasolacrimal duct obstruction and dacryocystitis in an extremely preterm infant. We discuss the diagnosis and multidisciplinary management of this challenging case.

Management of a Peristomal Abscess in a Patient With an Ileostomy: A Case Study.

BACKGROUND: Peristomal abscess (PA) is an uncommon but challenging peristomal skin complication. The initial treatment of the PA usually includes incision and drainage of the abscess, resulting in a peristomal wound. The presence of the wound makes it difficult to maintain a seal between the ostomy skin barrier and the peristomal skin resulting in frequent removal and application of the skin barrier to prevent leakage and allow for daily wound care. CASE: Ms T was a 52-year-old woman with an ileostomy resulting from a prior left hemicolectomy for colon cancer who developed a PA. Treatment of the PA was implemented, along with a modified 2-piece skin barrier that allowed access to the peristomal wound for daily dressing changes while maintaining a seal around the ostomy. CONCLUSION: The modified 2-piece skin barrier technique proved a successful treatment for the management of the PA without frequent changes of the ostomy pouching system.

Invasive pneumococcal disease serotype 23B1 causing multifocal septic arthritis, myositis and retroperitoneal abscess.

We describe a case of a previously healthy unvaccinated man in his 70s who developed penicillin-susceptible bacteraemic invasive pneumococcal disease due to non-vaccine serotype 23B with the unusual manifestations of multifocal myositis, intramuscular abscesses, polyarticular septic arthritis and synovitis. Blood cultures drawn prior to antibiotic therapy and culture of iliopsoas collection were helpful in making the diagnosis. At follow-up, he had persistent hip pain attributed to avascular necrosis of the head of femur, a possible late complication of his pyomyositis.

Serratia marcescens-associated subcutaneous abscess in a dog.

This report describes the clinical presentation and progression of a Serratia marcescens-associated subcutaneous abscess in a dog with hypothyroidism, hyperadrenocorticism and diabetes mellitus. The S. marcescens isolate was resistant to several antibiotics. Treatment with antibiotics and topical antiseptics was not successful.

"Can't Touch This!": Laparoscopic management of an obstructed uterus didelphys before and after treatment for pelvic inflammatory disease.

OBJECTIVE: To describe the laparoscopic management of an obstructed uterus didelphys before and after treatment for pelvic inflammatory disease. To compare the appearance of pelvic organs during active infection with their appearance after washout and appropriate antibiotic treatment, emphasizing the importance of knowing when to abort a procedure. DESIGN: Video demonstration of surgical and medical management considerations during a complex pelvic surgery. Visualization of tissue healing that occurs with appropriate antibiotic treatment. SETTING: Academic Center. PATIENT: A patient who presents for definitive surgical management of a uterus didelphys with an obstruction at her right hemicervix. Her presentation is complicated by a tubo-ovarian abscess. INTERVENTION: A uterus didelphys is classically defined as two hemiuteri with duplicated cervices with or without a longitudinal vaginal septum. Uterus didelphys may have an obstruction and/or communication between the two uterine horns, in which case patients may present with complications such as cyclic pelvic pain from hematometra or genital tract infection. This is a case report of a 14-year-old G0 who presented to the emergency department with two weeks of vaginal bleeding, severe diffuse abdominal pain, and malodorous vaginal discharge. Transabdominal ultrasound and a magnetic resonance imaging of the pelvis established a new diagnosis of a uterus didelphys with an obstruction at her right hemicervix and a fistulous tract connecting her right and left hemiuteri at the level of the internal cervical os. She was also found to have a 3 cm left ovarian cyst and a new finding of congenital absence of her right kidney. Patient was administered ceftriaxone, doxycycline, and metronidazole antibiotics as treatment of presumed pelvic inflammatory disease but experienced minimal improvement after 24 hours. The decision was made to proceed with surgical intervention. A survey of the pelvis revealed significant inflammation, friable peritoneum, and endometriosis. The uterine horns in didelphic configurations were visualized. The fimbriae at the left fallopian tube were notably splayed out, swollen, and inflamed. There was a notable large mass in the location where the ovarian cyst had been previously described on imaging. A large amount of purulent material was expressed when compressed, consistent with a tubo-ovarian abscess. The infection likely originated from the menstrual blood collection at the right obstructed cervix that ascended through the communication between the right and left hemiuteri. The pelvis was irrigated thoroughly. At this point, the decision was made to stop the procedure, pursue antibiotic treatment, and resolve the active infection before correcting her complex müllerian anomaly. Patient continued on her antibiotic course, which included piperacillin-tazobactam, while hospitalized, followed by a five-day course of amoxicillin-clavulanate. She was also placed on medroxyprogesterone acetate for menstrual suppression. MAIN OUTCOME MEASURE: Advantage of allowing time for antibiotic treatment and tissue healing before repair of a complex müllerian anomaly. RESULT: With antibiotic treatment, she recovered well postoperatively with resolution of her pain. Three months later, she returned to the operating room for definitive surgical management of her obstructed uterine didelphys. On laparoscopy, there was a significant improvement in tissue quality. Most notably, the fimbriae of the left fallopian tube were no longer inflamed. We proceeded with the planned correction of the complex müllerian anomaly. After resection of the right uterine horn, the fistula tract was identified and also resected. The defect in the right hemicervix was closed over, reinforcing the medial side of the left hemicervix. She had an uncomplicated postoperative recovery, and menses resumed without pain. CONCLUSIONS: The presented case provides unique insight into the tissue healing that occurs before and after antibiotic treatment. Knowing when to stop, especially in the setting of an active infection, is extremely important for performing a procedure safely, minimizing harm, and allowing for robust tissue repair. It is also important to optimize modifiable preoperative factors before correcting a complex müllerian anomaly. Assessing and reassessing the situation during a complex pelvic surgery is essential, especially in the setting of a complex müllerian anomaly where the preoperative examination and imaging may not be definitive.

Risk of embolic events before and after antibiotic treatment initiation among patients with left-side infective endocarditis.

PURPOSE: Embolic events (EEs) are a common complication of left-side infective endocarditis (IE). The aim of the present study was to identify risk factors for the occurrence of EEs before or after antibiotic treatment instauration among patients with definite or possible IE. METHODS: This retro-prospective study was conducted at the Lausanne University Hospital, Lausanne, Switzerland, from January 2014 to June 2022. EEs and IE were defined according to modified Duke criteria. RESULTS: A total of 441 left-side IE episodes were included (334: 76% were definite and 107; 24% possible IE). EE were diagnosed in 260 (59%) episodes; in 190 (43%) before antibiotic treatment initiation and 148 (34%) after. Central nervous system (184; 42%) was the most common site of EE. Multivariable analysis identified S. aureus (P 0.022), immunological phenomena (P < 0.001), sepsis (P 0.027), vegetation size ≥ 10 mm (P 0.003) and intracardiac abscess (P 0.022) as predictors of EEs before antibiotic treatment initiation. For EEs after antibiotic treatment initiation, multivariable analysis revealed vegetation size ≥ 10 mm (P < 0.001), intracardiac abscess (P 0.035) and prior EE (P 0.042), as independent predictors of EEs, while valve surgery (P < 0.001) was associated with lower risk for EEs. CONCLUSIONS: We reported a high percentage of EEs among patients with left-side IE; vegetation size, intracardiac abscess, S. aureus and sepsis were independently associated with the occurrence of EEs. In addition to antibiotic treatment, early surgery led to further decrease in EEs incidence.

Infective endocarditis surgery timing.

BACKGROUND: The optimum timing of surgical intervention in complicated left-sided infective endocarditis is not well established. Guidelines from various professional societies are not consistent regarding this. Data concerning this remains limited with conflicting results. METHODS: The national inpatient database (NIS) was used to identify patients hospitalized from the year 2016 to 2020 for infective endocarditis and who underwent surgical intervention for complicated left-sided endocarditis. Primary and secondary outcomes were analyzed in patients who had surgical intervention within 7 days (early surgery group) and after 7 days (late surgery group) of the index hospitalization. RESULTS: Primary outcome [composite of all-cause death, acute cerebrovascular accident (CVA), peripheral septic emboli, intracranial or intraspinal abscess, and cardiac arrest] was better in the early surgery group compared to the late surgery group 32.6 % vs 45.1 % [adjusted Odds ratio (aOR) = 0.59, 95 % Confidence interval (CI) = 0.52-0.67, P value â‰ª 0.001]. This was mainly due to better incidence of acute CVA (15.7 %vs 24 %, aOR = 0.59, CI = 0.50-0.69, P value â‰ª 0.001), peripheral septic emboli (18.5 % vs 27.3 %, aOR = 0.60, CI = 0.52-0.70, P value â‰ª 0.001) and intracranial/intraspinal abscess (1.2 % vs 4.74 %, aOR = 0.24, CI = 0.14-0.38, P value â‰ª 0.001). There is no difference in the incidence of all-cause in-hospital death (7.57 % vs 7.75 % aOR = 0.97, CI = 0.77-1.23, P value = 0.82) or cardiac arrest (3.4 % vs 3.54 %, aOR = 0.96, CI = 0.68-1.35, P value = 0.80). CONCLUSION: Surgical intervention within 7 days of index hospitalization is associated with a better incidence of acute CVA, peripheral septic emboli, and intracranial or intraspinal abscess but not with a better incidence of all-cause in-hospital death.
