Project description:INTRODUCTION:Mycoplasma hominis is associated with genito-urinary tract infection and adverse pregnancy outcomes. However, whether the species is a true pathogen or part of the genito-urinary tracts natural flora remains unclear. CASE PRESENTATION:A 41-year-old pregnant woman was admitted to our hospital at 38 weeks and 5 days of gestation owing to premature rupture of the membranes. The patient delivered by caesarean section. Subsequently, the patient complained of lower abdominal pain and had persistent fever. Enhanced computed tomography revealed pelvic abscesses. Gram staining of pus from the abscess and vaginal secretions indicated presence of polymorphonuclear leucocytes but no pathogens. Cultures on blood agar showed growth of pinpoint-sized colonies in an anaerobic environment within 48 h. Although administration of carbapenem and metronidazole was ineffective and we could not fully drain the abscess, administration of clindamycin led to clinical improvement. The isolates 16S rRNA gene and yidC gene sequences exhibited identity with those of M. hominis. CONCLUSION:Physicians should consider M. hominis in cases of pelvic abscesses where Gram staining yields negative results, small colonies are isolated from the abscess and treatment with ?-lactam antibiotics is ineffective.

Project description:Mycoplasma hominis, a well known cause of neonatal infection, has been reported as a pathogen in urogenital infections in adults; however, central nervous system (CNS) infections are rare. We report here the first case of M. hominis meningitis in China, post neurosurgical treatment for an intracerebral haemorrhage in a 71-year-old male.We describe a 71-year-old man who developed M. hominis meningitis after neurosurgical treatment and was successfully treated with combined azithromycin and minocycline therapy of 2 weeks duration, despite delayed treatment because the Gram stain of cerebrospinal fluid (CSF) yielded no visible organisms. The diagnosis required 16S rDNA sequencing analysis of the cultured isolate from CSF. Literature review of M. hominis CNS infections yielded 19 cases (13 instances of brain abscess, 3 of meningitis, 1 spinal cord abscess and 1 subdural empyema each). Delay in diagnosis and initial treatment failure was evident in all cases. With appropriate microbiological testing, antibiotic therapy (ranging from 5 days to 12 weeks) and often, multiple surgical interventions, almost all the patients improved immediately.Both our patient findings and the literature review, highlighted the pathogenic potential of M. hominis together with the challenges prompted by rare infectious diseases in particular for developing countries laboratories with limited diagnostic resources.

Project description:<h4>Introduction</h4>Surgical management of large talar dome cysts is challenging due to increased morbidity by associated cartilage damage and malleolar osteotomy. The purpose of this study is to evaluate the clinical and radiological outcome of endoscopic curettage and bone graft for large talar dome cysts.<h4>Methods</h4>This is a retrospective analysis of data for eight patients (eight feet) who were treated by arthroscopic curettage and grafting for large talar dome cysts. Seven cases were treated by posterior ankle arthroscopy as the lesion was located posteriorly while one case was treated by anterior ankle arthroscopy as the lesion was breached anteriorly.<h4>Results</h4>The final diagnosis, was; large osteochondral lesion of talus (two cases), aneurysmal bone cyst (ABC) (two case), intra-osseous ganglion (two cases), Chronic infection in talus (one case) and angiomatous lesion of the talus (one case). The mean follow up period was 18.3 (±3.06 SD) months (range 16-25 months). The median preoperative AOFAS score was 74.5 (±5.34 SD) points. The mean postoperative AOFAS score at one year follow up was 94.6 (±2.97 SD) points. None of the patient had recurrence of the lesion during follow up. Return to normal daily activity was achieved at 11.25 (±2.37 SD) weeks.<h4>Discussion</h4>In this short case series study, large talar dome bony cysts of different pathologies including aneurysmal bone cysts could be treated effectively by endoscopic curettage and bone grafting with no recurrence no complications during the follow-up period.

Project description:A temporal lobe abscess was diagnosed in a 57-year-old man. A urethral catheter had been inserted 12?days earlier, just prior to clot evacuation of a subacute haematoma secondary to an arterio-venous malformation. Fever persisted despite debridement and treatment with meropenem and vancomycin. Gram stains of operative samples showed no bacteria. Extended cultures grew pinpoint colonies after 5?days. Meanwhile, sequencing of bacterial 16S rDNA from operative specimens had identified Mycoplasma hominis; the bacterial colonies were subsequently similarly identified. The patient responded promptly following addition of oral doxycycline 100?mg two times per day. There is a growing literature of similar cases. Transient bacteraemia, following urinary catheterisation, with seeding of existing sites of inflammation is the proposed explanation. Urethral carriage of M. hominis is 15% and catheterisation is a common procedure. Mycoplasma hominis maybe more common than appreciated, especially as the need for extended cultures makes a correct diagnosis less likely.

Project description:To evaluate the efficacy and safety of second uterine curettage in lieu of chemotherapy for patients with low-risk, nonmetastatic gestational trophoblastic neoplasia (GTN) and to evaluate whether response to second curettage is independent of patient age, World Health Organization (WHO) risk score, registration human chorionic gonadotropin (hCG) level, lesion size, and depth of myometrial invasion measured on ultrasound examination.This was a cooperative group multicenter prospective phase II study. Prestudy testing included quantitative hCG level, pelvic ultrasonography, and chest radiography. Patients were categorized according to WHO risk scoring criteria (low risk with a score of 0-6).Sixty-four women with newly diagnosed low-risk, nonmetastatic GTN were enrolled. Four patients were excluded. Twenty-four patients (40%) (lower 95% confidence limit 27.6%) were cured after second curettage. An additional two patients (3%) achieved a complete response but did not complete follow-up. Overall, 26 of 60 patients were able to avoid chemotherapy. Surgical failure was observed in 34 women (59%) and was more common in women 19 years old or younger or 40 years old or older. One case of grade 1 uterine perforation was successfully managed by observation. Four grade 1 and one grade 3 uterine hemorrhages were reported. New metastatic disease (lung) was identified in one of these women after second curettage. In three patients (surgical failures), the second curettage pathology was placental site trophoblastic tumor, and it was placental nodule in one additional patient.Second uterine curettage as initial treatment for low-risk, nonmetastatic GTN cures 40% of patients without significant morbidity.ClinicalTrials.gov, https://clinicaltrials.gov/, NCT00521118.

Project description:BACKGROUND:Aggregatibacter aphrophilus, a commensal of the oro-pharyngeal flora and member of the HACEK group of organisms, is an uncommonly encountered clinical pathogen. It has already been described as the causative agent of brain abscesses, empyema, meningitis, sinusitis, otitis media, bacteriemia, pneumonia, osteomyelitis, peritonitis, endocarditis and wound infections. Herein we report the first case of bartholinitis due to A. aphrophilus. CASE PRESENTATION:A 33-year-old woman was admitted for a 3-day genital pain without fever and urinary functional signs. The abscess was incised and drained; A. aphrophilus was the only micro-organism that grew from the pus. The patient received no antibiotics; the clinical course was favourable. CONCLUSION:This case highlights the importance of an effective treatment of recurrent bartholinitis such as a cold resection of the gland. It is presented for its rarity.

Project description:Although aneurysmal bone cysts (ABCs) are benign tumours, they have the potential to be locally aggressive. Various treatment approaches, such as en bloc resection, open curettage, radiotherapy, sclerotherapy, and embolization have been proposed, but the most appropriate treatment should be selected after considering the risk of tumour recurrence and treatment complications. Endoscopic curettage (ESC) may be a less invasive alternative to open curettage for ABC treatment. We aimed to describe the use of ESC for the treatment of ABCs and to report our clinical outcomes, including the incidence rate of recurrence, radiological appearance at final follow-up, time to solid union, complications, and postoperative function.Between 1998 and 2015, 30 patients (18 men and 12 women; mean age, 17.4 years) underwent ESC for the treatment of primary ABCs at our hospital (mean postoperative follow-up, 55 months). ESC was performed under arthroscopic guidance for direct visualization, and curettage extended until normal bone was observed in the medullary cavity. To investigate bone healing after ESC, we evaluated the consolidation of cysts at the final evaluation (based on the modified Neer classification) and time to solid union after surgery, which was defined as sufficient cortical bone thickness to prevent fracture and allow physical activities.Recurrence was identified in 3 cases (10%). Curative outcomes were obtained after repeated ESC or open curettage. A log-rank analysis indicated that age?<?10 years (p?=?0.004) and contact of the tumour with the physis (p?=?0.01) increased the risk of tumour recurrence. Residual tumours were identified in 9 cases (30%); these lesions remained inactive over the extended follow-up period. The average time to solid union after endoscopic curettage was 3.2 months. Transient radial nerve palsy was identified in 1 case. Good postoperative functional recovery occurred in all cases.ESC is a minimally invasive technique for the treatment of ABCs, and the tumour recurrence rate is comparable to that of other standard procedures. However, the application of this method should be carefully considered, especially for patients <?10 years and when the tumour comes in contact with the physis.

Project description:Hereditary haemorrhagic telangiectasia (HHT) is a rare inherited autosomal-dominant vascular dysplasia involving multiple organs. Brain abscess is an uncommon and potential fatal complication. We report a case of HHT caused by a novel ENG mutation who initially presented as brain abscess. The patient, with a family history of epistaxis, presented with fever, headache and right-sided haemiparesis. Upon examination, brain MRI showed a contrast-enhanced abscess on the left fronto-parietal region. Open brain drainage was performed and pus culture yielded Actinomyces meyeri. The chest image revealed multiple pulmonary arterio-venous fistulas. HHT was diagnosed according to Curacao criteria. Genetic analysis revealed a novel duplication on exon 6 of ENG gene, which segregates with symptomatic subjects in her family. Clinicians should be cautiously aware of HHT as a differential diagnosis if patients presented with an unknown entry source of intracerebral infections.
