Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice.

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines). PREOPERATIVE PATIENTS' INFORMATION: Each patient must be informed concerning the risks associated with POP surgery (EO). HEMORRHAGE, HEMATOMA: Vaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO). BLADDER INJURY: When a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO). URETER INJURY: After ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO). RECTAL INJURY: Regardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO). VAGINAL WALL INJURY: After vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO). MESH INFECTION (ABSCESS, CELLULITIS, SPONDYLODISCITIS): Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO). When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO). When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient. BOWEL OCCLUSION RELATED TO NON-CLOSURE OF THE PERITONEUM: Peritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO). URINARY RETENTION: Preoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO). POSTOPERATIVE PAIN: Before POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C). When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO). When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO). When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO). Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO). Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO). POSTOPERATIVE DYSPAREUNIA: When de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO). VAGINAL MESH EXPOSURE: To reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C). When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material. When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered. When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO). When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh. Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO). When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO). SUTURE THREAD VAGINAL EXPOSURE: For women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed. BLADDER AND URETERAL MESH EXPOSURE: When bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B). Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

Clinical characteristics of native vertebral osteomyelitis in patients with history of acupuncture.

BACKGROUND: Considering that vertebral osteomyelitis (VO) can occur via various routes, it can be predicted that clinical characteristics may vary depending on the route of infection or risk factors of the disease. In this study, differences in clinical characteristics, causative pathogens, clinical features and prognosis were investigated in patients of native vertebral osteomyelitis with history of acupuncture. METHODS: This retrospective study was conducted at Kyung Hee University Hospital at Gangdong, Seoul. We extracted data of patients diagnosed with VO from May 2006 to February 2021 using an electronic database. Data on demography, clinical presentation, treatment, causative organisms and clinical outcomes were identified and compared according to the history of acupuncture. RESULTS: A total of 100 patients with VO were reviewed, among which 34 patients had a history of acupuncture prior to the diagnosis of VO. The frequency of Gram-positive cocci (GPC) was significantly higher in the acupuncture group than in the non-acupuncture group (p = 0.016). Abscess was observed more frequently in the acupuncture group than in the non-acupuncture group (p = 0.01). There was no difference in neurological sequelae and recurrence between the two groups. There was no difference in mortality between the two groups. (p = 0.098) CONCLUSION: This study suggests that confirming a history of acupuncture may help predict the pathogen or clinical characteristics of the disease. If the patient has a history of acupuncture, GPC can be considered as the causative organism, and the findings that abscesses and surgical treatment are more common may be helpful in evaluating patients.

Impaired ESX-3 Induces Bedaquiline Persistence in Mycobacterium abscessus Growing Under Iron-Limited Conditions.

ESX-3 is a secretion pathway which is essential for mycobactin-mediated iron acquisition under iron-limited conditions. Although present in all Mycobacterium sp., ESX-3 remains to be elucidated in Mycobacterium abscessus. In the study reported here, impaired ESX-3 seriously restricts the growth of M. abscesses under iron-limited conditions; growth is salvaged by functional ESX-3 or iron supplementation. Notably, impaired ESX-3 does not kill M. abscesses when environmental iron is insufficient but induces persistence to bedaquiline, a diarylquinoline class antibiotic used to treat multidrug-resistant mycobacteria. One potential mechanism contributing to persistence is the iron deficiency due to impaired ESX-3 suppressing succinate dehydrogenase activity, which dysregulates the tricarboxylic acid cycle and inactivates bedaquiline. Experiments conducted here also demonstrate that the regulator, MtrA, can bind ESX-3 and promote the survival of M. abscessus. As such, this study suggests that a novel pathway involving MtrA, ESX-3, iron metabolism, and the TCA cycle contributes to bedaquiline persistence in M. abscesses growing under iron-limited conditions.

[Management of secondary lesions in ano-perineal Crohn's disease]. / Prise en charge des lésions secondaires de la maladie de Crohn anopérinéale.

MANAGEMENT OF SECONDARY LESIONS IN ANO-PERINEAL CROHN'S DISEASE. Anoperineal involvement in Crohn's disease is common and affects around 1/3 of patients during their disease. It constitutes a pejorative factor with an increased risk of permanent colostomy and proctectomy and is associated with a major deterioration in quality of life. Secondary anal lesions in Crohn's disease are fistulas and abscesses. They are difficult to treat and often recurrent. A multidisciplinary medico-surgical management in several stages is essential. The classic sequence is based on a first phase of drainage of fistulas and abscesses, a second phase of medical treatment based primarily on anti-TNF alpha and finally a third phase of surgical closure of the fistula tract(s). Conventional closure techniques such as biologic glue, plug, advancement flap and intersphincteric ligation of the fistula tract have limited effectiveness, are not always feasible, require technical skills and some have an impact on anal continence. In recent years, we have witnessed a real enthusiasm generated by the arrival of cell therapy. This has not spared proctology since adipose-derived allogeneic mesenchymal stem cells have had Marketing Authorisation and have been reimbursed in France since 2020 in the treatment of complex anal fistulas in Crohn's disease after failure of at least one biologic therapy. This new treatment offers an additional alternative in patients often in a situation of therapeutic impasse. Preliminary results in real life are satisfactory with a good safety profile. However, it will be necessary to confirm these results in the longer term and to work to determine the profile of the patients who could benefit the most from this expensive therapy.

PRISE EN CHARGE DES LÉSIONS SECONDAIRES DE LA MALADIE DE CROHN ANOPÉRINÉALE. L'atteinte anopérinéale de la maladie de Crohn est fréquente ; elle affecte environ un tiers des patients durant leur maladie. Elle constitue un facteur péjoratif responsable d'une majoration du risque de colostomie définitive et de proctectomie, et est associée à une altération majeure de la qualité de vie. Les lésions anales secondaires de la maladie de Crohn sont des fistules et des abcès. Elles sont difficiles à traiter et souvent récidivantes. Une prise en charge multidisciplinaire médico-chirurgicale en plusieurs étapes s'impose. La séquence classique se fonde sur une phase de drainage des fistules et des abcès, une phase de traitement médical fondé en priorité sur les anti-TNF alpha et enfin une phase de fermeture chirurgicale du (ou des) trajet(s) fistuleux. Les techniques de fermeture classiques comme la colle biologique, le plug, le lambeau d'avancement et la ligature intersphinctérienne du trajet fistuleux ont une efficacité limitée, ne sont pas toujours réalisables, nécessitent des compétences techniques et ont, pour certaines, un impact sur la continence anale. Ces dernières années, l'arrivée de la thérapie cellulaire suscite un véritable enthousiasme. Cet engouement n'a pas épargné la proctologie, puisque les cellules souches mésenchymateuses (CSM) allogéniques d'origine adipocytaires ont obtenu une autorisation de mise sur le marché (AMM), sont commercialisées et remboursées en France depuis 2020 dans le traitement des fistules anales complexes de la maladie de Crohn en échec d'au moins une biothérapie. Cette thérapie offre une alternative supplémentaire à des patients souvent en situation d'impasse thérapeutique. Les résultats préliminaires en vraie vie sont satisfaisants, avec un bon profil d'innocuité. Toutefois, il faudra confirmer ces résultats à plus long terme et travailler à identifier le profil des patients qui pourraient bénéficier au mieux de cette thérapie onéreuse.

Tuberculosis revisted: classic imaging findings in childhood.

Tuberculosis (TB) remains one of the major public health threats worldwide, despite improved diagnostic and therapeutic methods. Tuberculosis is one of the main causes of infectious disease in the chest and is associated with substantial morbidity and mortality in paediatric populations, particularly in low- and middle-income countries. Due to the difficulty in obtaining microbiological confirmation of pulmonary TB in children, diagnosis often relies on a combination of clinical and radiological findings. The early diagnosis of central nervous system TB is challenging with presumptive diagnosis heavily reliant on imaging. Brain infection can present as a diffuse exudative basal leptomeningitis or as localised disease (tuberculoma, abscess, cerebritis). Spinal TB may present as radiculomyelitis, spinal tuberculoma or abscess or epidural phlegmon. Musculoskeletal manifestation accounts for 10% of extrapulmonary presentations but is easily overlooked with its insidious clinical course and non-specific imaging findings. Common musculoskeletal manifestations of TB include spondylitis, arthritis and osteomyelitis, while tenosynovitis and bursitis are less common. Abdominal TB presents with a triad of pain, fever and weight loss. Abdominal TB may occur in various forms, as tuberculous lymphadenopathy or peritoneal, gastrointestinal or visceral TB. Chest radiographs should be performed, as approximately 15% to 25% of children with abdominal TB have concomitant pulmonary infection. Urogenital TB is rare in children. This article will review the classic radiological findings in childhood TB in each of the major systems in order of clinical prevalence, namely chest, central nervous system, spine, musculoskeletal, abdomen and genitourinary system.

Outcomes of surgical treatment of diverticular abscesses after failure of antibiotic therapy.

Management of diverticular abscess (DA) is still controversial. Antibiotic therapy is indicated in abscesses ≤ 4 cm, while percutaneous drainage/surgery in abscesses > 4 cm. The study aims to assess the role of antibiotics and surgical treatments in patients affected by DA. We retrospectively analyzed 100 consecutive patients with DA between 2013 and 2020, with a minimum follow-up of 12 months. They were divided into two groups depending on abscess size ≤ or > 4 cm (group 1 and group 2, respectively). All patients were initially treated with intravenous antibiotics. Surgery was considered in patients with generalized peritonitis at admission or after the failure of antibiotic therapy. The primary endpoint was to compare recurrence rates for antibiotics and surgery. The secondary endpoint was to assess the failure rate of each antibiotic regimen resulting in surgery. In group 1, 31 (72.1%) patients were conservatively treated and 12 (27.9%) underwent surgery. In group 2, percentages were respectively 50.9% (29 patients) and 49.1% (28 patients). We observed 4 recurrences in group 1 and 6 in group 2. Recurrence required surgery in 3 patients/group. We administered amoxicillin-clavulanic acid to 74 patients, piperacillin-tazobactam to 14 patients and ciprofloxacin + metronidazole to 12 patients. All patients referred to surgery had been previously treated with amoxicillin-Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation clavulanic acid. No percutaneous drainage was performed in a hundred consecutive patients. Surgical treatment was associated with a lower risk of recurrence in patients with abscess > 4 cm, compared to antibiotics. Amoxicillin-clavulanic acid was associated with a higher therapeutic failure rate than piperacillin-tazobactam/ciprofloxacin + metronidazole.

The Optimal Primary Treatment for Pediatric Perianal Abscess and Anal Fistula: A Systemic Review and Meta-Analysis.

BACKGROUND: Perianal abscesses and anal fistulas are common. The principle of intention-to-treat has not been considered in previous systemic reviews. Thus, the comparison between primary and post-recurrence management was confused, and the recommendation of primary treatment is obscure. The current study aims to identify the optimal initial treatment for pediatric patients. METHODS: Using PRISMA guidelines, studies were identified from MEDLINE, EMBASE, PubMed, Cochrane Library, and Google Scholar without any language or study design restriction. The inclusion criteria include original articles or articles with original data, studies of management for a perianal abscess with or without anal fistula, and patient age of <18 years. Patients with local malignancy, Crohn's disease, or other underlying predisposing conditions were excluded. Studies without analyzing recurrence, case series of <5, and irrelevant articles were excluded in the screening stage. Of the 124 screened articles, 14 articles had no full texts or detailed information. Articles written in a language other than English or Mandarin were translated by Google Translation first and confirmed with native speakers. After the eligibility process, studies that compared identified primary managements were then included in the qualitative synthesis. RESULTS: Thirty-one studies involving 2507 pediatric patients met the inclusion criteria. The study design consisted of two prospective case series of 47 patients and retrospective cohort studies. No randomized control trials were identified. Meta-analyses for recurrence after initial management were performed with a random-effects model. Conservative treatment and drainage revealed no difference (Odds ratio [OR], 1.222; 95% Confidential interval [CI]: 0.615-2.427, p = 0.567). Conservative management had a higher risk of recurrence than surgery without statistical significance (OR 0.278, 95% CI: 0.109-0.707, p = 0.007). Compared with incision/drainage, surgery can prevent recurrence remarkably (OR 4.360, 95% CI: 1.761-10.792, p = 0.001). Subgroup analysis of different approaches within conservative treatment and operation was not performed for lacking information. CONCLUSION: Strong recommendations cannot be made due to the lack of prospective or randomized controlled studies. However, the current study based on real primary management supports initial surgical intervention for pediatric patients with perianal abscesses and anal fistula to prevent recurrence. LEVEL OF EVIDENCE: Type of study: Systemic review; Evidence level: Level II.

[Sole abscess (Pododermatitis purulenta superficialis) in a Bactrian camel - diagnosis, treatment, and healing process]. / Sohlenabszess (Pododermatitis purulenta superficialis) bei einem Trampeltier ­ Diagnostik, Therapie und Heilungsverlauf.

An approximately 14-year-old female Bactrian camel was referred to the University Clinic for Ruminants with left hindlimb lameness of two weeks duration. All findings of the general clinical examination were within normal limits. Orthopedic examination revealed a left supporting limb lameness score of 2 with moderate weight-shifting and reluctance to bear weight on the lateral toe at walk. The camel was sedated (0.24 mg/kg BW xylazine i.m.+1.92 mg/kg BW ketamine i.m., 0.04 mg/kg BW butorphanol) and rolled in lateral recumbency for further investigations. Sonographic examination of the cushion of the left hindlimb revealed an abscess of diameters of 11×2.3 cm impinging both digits between the sole horn and lateral and medial cushions. The abscess was opened under local infiltration anesthesia after a 5×5 cm incision at the central sole area, the abscess capsule removed with a sharp curette and the abscess cavity flushed. The wound was then bandaged. Postoperative treatment consisted of bandage changes every 5-7 days. For these procedures the camel was repeatedly sedated. At the first change the xylazine dosage was the same for surgery, and sequentially the dosage could be reduced (0.20 mg/kg BW i.m.), but finally increased for the last dressing changes (0.22 mg/kg BW i.m.). Ketamine dosages were also reduced slightly throughout the hospitalization period (1.51 mg/kg BW i.m.), enabling a reduction of the recovery period duration. After 6 weeks of regular bandage changes the wound had healed completely with a new horn layer and showing no lameness the camel could be discharged.

Cholecystoappendiceal Fistula From Appendiceal Adenocarcinoma Requiring a Right Hemicolectomy With Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy.

Bilioenteric fistulae are rare and difficult to manage complications of chronic cholecystitis. While cholecystoduodenal and cholecystocolic fistulae are more common, a cholecystoappendiceal fistula is an extremely rare finding. We report the presentation and operative management of a 59-year-old male with cholecystoappendiceal fistula and associated abscess in the gallbladder fossa. The patient was appropriately resuscitated, the abscess drained by interventional radiology, and after a complete workup, underwent a laparoscopic appendectomy and cholecystectomy. Pathology revealed moderately differentiated appendiceal adenocarcinoma requiring a right hemicolectomy with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC). He has recovered well postoperatively with no complications. This case highlights the importance of having a very high index of suspicion for underlying malignancy when managing a fistula of any kind. To the best of our understanding, this is only the second reported case of a cholecystoappendiceal fistula.

[Guidelines for the Management of Patients with Hidradenitis Suppurativa]. / Recomendações na Abordagem do Doente com Hidradenite Supurativa.

Hidradenitis suppurativa is a chronic and recurrent inflammatory dermatosis characterized by the presence of inflammatory nodules and abscesses in the apocrine gland-rich areas that may progress to suppurative fistulas and scars. Despite being considered one of the dermatological conditions with the greatest impact on patient quality of life, it is often underdiagnosed. Hidradenitis suppurativa, especially in its severe forms, is associated with numerous comorbidities, so a holistic and multidisciplinary perspective is crucial for the management of these patients. The therapeutic approach is complex and challenging. The medical treatment options are diverse and must be adapted to clinical presentation and disease severity. Surgical therapy should be considered as an adjuvant to medical treatment, particularly in refractory cases and in the presence of scars or anatomical and/or functional mutilation. These recommendations reflect the main aspects of the management of the patient with hidradenitis suppurativa and are addressed to all healthcare professionals who take part in their follow-up.

A hidradenite supurativa é uma dermatose inflamatória crónica e recorrente que se caracteriza pela presença de nódulos inflamatórios e abcessos nas áreas ricas em glândulas apócrinas, que podem evoluir para fístulas supurativas e cicatrizes. Apesar de ser considerada uma das patologias dermatológicas com maior impacto na qualidade de vida dos doentes, é frequentemente subdiagnosticada. A hidradenite supurativa, sobretudo nas suas formas mais graves, associa-se a diversas comorbilidades, pelo que é fundamental adotar uma perspetiva holística e multidisciplinar na gestão destes doentes. A abordagem terapêutica é complexa e desafiante. A terapêutica médica é multifacetada e deve ser adaptada à apresentação clínica e gravidade da doença. A terapêutica cirúrgica deverá ser equacionada como adjuvante à terapêutica médica, em particular nos casos refratários e perante cicatrizes ou mutilação anatómica e/ou funcional. As presentes recomendações pretendem reunir os principais aspetos da abordagem ao doente com hidradenite supurativa e destinam-se a todos os profissionais de saúde envolvidos no seu acompanhamento.

Serious spondylodiscitis, septic sacroiliitis and multiple abscesses after ozone therapy for low back pain: A case report on good response to combined treatment with empiric antibiotic and neridronate.

Ozone therapy is a minimally invasive technique now widely used for the treatment of pain due to herniated discs. In literature there are conflicting results concerning its real effectiveness and few data about its possible complications. In this case report we present a case of spondylodiscitis, septic arthritis and gluteal abscess following the execution of 4 sessions of ozone therapy. Given the impossibility of isolating the etiological agent, an empirical antibiotic therapy with an overall duration of 6 weeks was set up, initially with daptomycin and ceftriazone, to which was added after 2 days metronidazole, administered intravenously; after 20 days the cephalosporin was replaced with oral amoxicillin/clavulanate. Neridronate was added to treat bone edema and to avoid bone erosion. The patient showed improvement of both clinical conditions and inflammation indexes, and was discharged after 4 weeks without further complications at follow-up. Few cases are reported in the literature about spondylodiscitis secondary to ozone treatment, and just 1 case is described about the use of neridronate as additive drug to antibiotic treatment in spondylodiscitis to avoid bone disruption and surgery complications.

Positive Predictive Value of Diagnosis Codes for Hidradenitis Suppurativa and Cutaneous Abscess.

BACKGROUND: Requisite to the application of clinical databases for observational research in hidradenitis suppurativa (HS) is the identification of an accurate case cohort. There is limited information on the validity of using diagnosis codes to identify HS and cutaneous abscess (CA) case cohorts. OBJECTIVES: The objective of the study was to assess the validity in utilizing diagnosis codes to establish the HS and CA cohorts from an integrated health system clinical database. METHODS: In this retrospective study, we evaluated a case-finding algorithm for HS which included the presence of at least one diagnosis code for HS and no diagnosis codes for CA of the axilla, groin, perineum, or buttock at any time. We evaluated a case-finding algorithm for CA which included the presence of at least one diagnosis code for abscess in the axilla, groin, perineum, or buttock and no codes for HS at any time. Medical records for a random sample of 100 patients meeting algorithm criteria were reviewed and adjudicated by dermatologists for accuracy of diagnosis. The positive predictive values (PPVs) of the ICD code-based case definitions were calculated, using the dermatologist's chart-based adjudication as the reference standard. RESULTS: Among 100 HS patients, median age (interquartile range) in the HS cohort was 33 (24.75, 43.25) years. HS patients were predominantly female (82%) and white (70%). Median age among 100 CA patients was 31.5 (95% CI 6.75, 47.25) years. The majority of CA patients were female (56%) and white (69%). The PPVs of the ICD-based case-finding algorithms for HS and CA were 88% (95% CI 81.6-94.4%) and 75.0% (95% CI 66.5-83.5%), respectively. CONCLUSION: The case-finding algorithms employing at least one diagnosis code for HS and CA of the axilla, groin, perineum, or buttock, with the exclusion of the other's diagnosis codes, has good to strong PPV and may provide balance in achieving accuracy and adequate power for cohorts identified within clinical databases.

Breast Abscess Healing with Homoeopathy: A Case Report.

Context: Breast abscess is the most common complication of acute bacterial mastitis usually referred to as pyogenic mastitis. It is usually encountered during lactation due to an infection with Staphylococcus aureus and streptococcal bacteria. These bacteria produce a severe inflammatory reaction leading to pus formation which is mainly treated by ultrasound-guided drainage or fine needle aspirations. We find that in this condition homoeopathic treatment can play an important role as it avoids such surgical procedures and helps in healing in a most gentle and rapid way. We report a successful single case study that opens up opportunities to take up more such cases to strengthen the results of this report. Case summary: A 23-year-old lactating mother came with complaints of pain and swelling with a collection of pus in the breast region and decreased breast milk secretion. Individualised homoeopathic medicine Silicea 200C was given to hasten suppuration and Belladonna 200C to treat inflammation.Thus, this case shows us how only few doses of medicine may be quickly helpful in managing a case of breast abscess without the need of any surgical procedures.

Rates and Predictors of Long-term Clinical Outcomes in Patients With Perianal Crohn's Disease on Biologic Therapy.

BACKGROUND AND GOALS: Perianal Crohn's disease (pCD) represents an aggressive phenotype with limited studies on long-term outcomes. We evaluated 5-year outcomes of these patients on biologic therapies. METHODS: We performed a retrospective analysis of patients with pCD at a tertiary medical center. We used Kaplan-Meier curves to estimate rates and multivariate logistic regression to identify predictors of long-term outcomes. RESULTS: We included 311 patients with pCD of which 168 patients were started on biologics [138 anti-tumor necrosis factor (TNF) α, 14 vedolizumab, 16 ustekinumab] at the time of diagnosis. Anti-TNF use at the time of diagnosis was associated with decreased rates of perianal abscess recurrence [hazard ratio (HR)=0.48, 95% confidence interval (CI): 0.32-0.74], whereas ustekinumab use was associated with increased rates of perianal fistula closure (HR=3.58, 95% CI: 1.04-12.35) and decreased rates of perianal abscess recurrence (HR=0.20, 95% CI: 0.07-0.56) at follow-up. Among patients who failed their first anti-TNF, switching to another anti-TNF was associated with decreased rates of colectomy (HR=0.20, 95% CI: 0.04-0.90) and permanent diversion (HR=0.16, 95% CI: 0.03-0.94) compared with ustekinumab, whereas vedolizumab use was associated with decreased perianal fistula closure (HR=0.22, 95% CI: 0.05-0.96) compared with ustekinumab. Predictors of colectomy included colonic disease (odds ratio=2.71, 95% CI: 1.36-5.38) and anal stenosis (odds ratio=4.44, 95% CI: 1.59-12.43). CONCLUSION: Type of biologic use at the time of pCD diagnosis or after first anti-TNF failure may be associated with long-term outcomes in patients with pCD.

[A Case of Radical Resection after Neoadjuvant Chemotherapy for Rectal Cancer with Pelvic Abscess].

A 66-year-old man with a history of frequent diarrhea was diagnosed with rectal cancer with obstruction and a pelvic abscess. Following a transverse colostomy, he was referred to our hospital. The initial diagnosis was rectal cancer(cT4a N1bM0, cStage Ⅲb)and a pelvic abscess due to tumor perforation. To address this condition, we performed neoadjuvant chemotherapy using a combination of 5-fluorouracil, Leucovorin, oxaliplatin, and irinotecan(FOLFOXIRI). Following 6 courses of FOLFOXIRI, the abscess disappeared and no signs of tumor progression and distant metastases were detected. Subsequently, we performed radical resection with D3LD2 lymph node dissection, leading to a pathological diagnosis of ypT3N1aM0, ypStage Ⅲb. The patient then underwent adjuvant chemotherapy with capecitabine and oxaliplatin(CAPOX). No recurrence was observed after 9 months of follow-up.

Masticator space abscess following intramuscular stimulation.

A male in his 50s presented to the hospital with preauricular tenderness, trismus and dysphagia. He had intramuscular stimulation of his left temporomandibular joint region performed 4 days prior and described worsening pain and swelling since. A CT scan revealed an abscess involving the left masticator space. Incision and drainage of the abscess was performed, and the patient was discharged home on oral antibiotics 11 days later. This is the first report of masticatory space abscess following intramuscular stimulation of the temporomandibular joint area. Acupuncture and intramuscular stimulation are common complementary medicine therapies that are generally considered safe; however, adverse events such as deep neck space infection have been reported in the literature. Current regulation of training requirements and licensure for needling therapies is highly variable. Standardisation of training and practice guidelines may help mitigate the risk of adverse events related to needling therapies in the future.

Pseudocatalytic Hydrogels with Intrinsic Antibacterial and Photothermal Activities for Local Treatment of Subcutaneous Abscesses and Breast Tumors.

The intimate relationship between bacteria and tumors has triggered a lot of activities in the development and design of bioactive materials to concurrently respond to antitumor and antibacterial demands. Herein, a pseudocatalytic hydrogel (AM-I@Agar) with intrinsic antibacterial and photothermal activities, synthesized by incorporating prefabricated amylose-iodine nanoparticles into low-melting-point agarose hydrogel, is explored as a bioactive agent for local treatment of subcutaneous abscesses and breast tumors. The AM-I@Agar hydrogel depicts the ability of pseudocatalytic O2 generation from H2 O2 to alleviate hypoxia. Meanwhile, the AM-I@Agar hydrogel exhibits temperature self-regulation features, beneficial for avoiding thermal injury during photothermal therapy owing to thermochromic properties. Upon local injection into a subcutaneous abscess, methicillin-resistant Staphylococcus aureus is effectively eliminated by the AM-I@Agar hydrogel, and complete skin recovery is achieved in 8 d, demonstrating much better antibacterial effects compared with penicillin, a small-molecule antibiotic. AM-I/5-FU@Agar hydrogel, obtained after loading 5-fluorouracil (5-FU), significantly inhibits tumors in both normal 4T1 tumor-bearing mice and MRSA-infected 4T1 tumor-bearing mice models via a synergistic photothermal-chemo effect, and shows treatment efficiency superior to that achieved with photothermal therapy or 5-FU alone. This work provides a concept for the design and development of bioactive agents for potential management of bacteria-associated cancer.

Prostatic Abscess Combined With Spleen Abscess Due to Multi-Drug-Resistant Gram-Negative Bacilli: A Case Report and Literature Review.

The prostatic abscess is a rare complication of a bacterial infection of the prostate. Since the early use of potent antibiotics to treat urinary tract infections, the incidence of the prostatic abscess has declined significantly. In keeping with that, prostatic abscess combined with abscesses in the spleen or other distant organs become an extremely rare but fatal clinical condition. Here, we present a case of prostate and spleen abscess due to multi-drug-resistant gram-negative bacilli without obvious risk factors. The patient initially complained of high-grade fever and dysuria. After screening the source of infection by computed tomography (CT) scans, prostate and spleen abscesses were diagnosed. In addition, extended-spectrum beta-lactamase positive Escherichia coli was detected both in urine and blood culture. The patient was successfully treated by a transurethral resection of the prostate followed by splenic puncture and drainage, as well as intravenous administration of meropenem. Although the prostate abscess combined with spleen abscess was rare, the possibility of dissemination in remote tissues should be taken into consideration before the surgical treatment of prostatic abscesses. The concurrent drainage of multiple abscesses followed by intensive and sensitive antibiotics was safe and effective for indicated patients.

The first Aotearoa New Zealand case of NUDT15-variant-related thiopurine-induced myelotoxicity.

A 37-year-old Han Chinese man, with a history of severe ulcerative colitis with incomplete response to oral glucocorticoids, was commenced on azathioprine [AZA] 200mg once a day. His pre-treatment thiopurine S-methyltransferase [TPMT] levels were in the normal range. Eleven days later he developed symptoms of stomatitis and gingivitis. Chinese herbal medications were taken in an attempt to treat these symptoms. He presented to the emergency department with this, with normal vital signs. A full blood count five days post-onset of symptoms showed pancytopenia with an absolute neutrophil count [ANC] of 0.0x10(9)/l, C-reactive protein was 120 mg/L. Initial chest radiograph, urinalysis and peripheral blood cultures were unremarkable and he was commenced on broad spectrum antibiotics and granulocyte colony stimulating factor [G-CSF]. He remained an inpatient under the gastroenterology team for 16 days and developed infectious complications of herpes simplex stomatitis, oral candidiasis, dental abscess, and scalp abscess. On day 16 his ANC recovered to 1.0x10(9)/L and was discharged from the hospital. He underwent nudix hydrolase 15 [NUDT15] genotyping and was found to have homozygosity for the variant NUDT15:c.415C>T. This case demonstrates the importance of pre-treatment testing for NUDT15 genetic variants, to predict the risk of severe leucopaenia, particularly in a patient of East Asian ethnicity.

Paravertebral abscess and bloodstream infection caused by Burkholderia pseudomallei after acupuncture: a case report.

BACKGROUND: Various pathogenic bacterial infections caused by acupuncture have raised widespread concern, but paravertebral abscesses and bloodstream infections of Burkholderia pseudomallei (B.pseudomallei) after acupuncture have not been reported. CASE PRESENTATION: A 49-year-old man was admitted to hospital with recurrent back pain and fever for 1 month, along with the finding of undiagnosed diabetes. He was considered to have tuberculosis because of unrelieved high fever and pulmonary nodules. Bilateral blood culture suggested B.pseudomallei infection, MRI of the lumbar spine suggested paravertebral abscess, and the final diagnosis was paravertebral abscess and bloodstream infection after acupuncture combined with migrating lung infection. He was discharged after abscess debridement and intensive anti-infective therapy, but no further oral antibiotics were administered because of his poor adherence. More than 5 months later, he was readmitted with the urine culture findings of B.pseudomallei. No other abscess formation was observed and he received oral antibiotics for more than 3 months without recurrence. CONCLUSIONS: Acupuncture may lead to B.pseudomallei infection in high-risk groups, and inadequate treatment can lead to recurrent infections.
