Analgesia for the treatment of acute pancreatitis: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: Gastrointestinal hospitalisations in the USA cause over US$130 billion in expenditures, and acute pancreatitis is a leading cause of these hospitalisations. Adequate pain control is one of the primary treatment goals for acute pancreatitis. Though opioids are commonly used for analgesia in these patients, there have been concerns about short-term and long-term side effects of using opioids. Recently, non-opioid medications have been studied to treat pain in patients with acute pancreatitis. This systematic review and network meta-analysis aims to assess the comparative efficacy of analgesic medication for non-severe, acute pancreatitis. METHODS AND ANALYSIS: We will search multiple electronic databases for randomised controlled trials that study pain management in patients with non-severe, acute pancreatitis. The intervention will be any analgesic for acute pancreatitis in the hospital setting. The comparison group will be patients who received a placebo or other active interventions for pain management. The primary outcomes of interest include pain scores and the need for supplementary analgesia. The secondary outcomes will be serious adverse events, local complications, progression to severe pancreatitis, transfer to the intensive care unit, length of hospitalisation, time to start enteral feeds, 30-day all-cause mortality and Quality of Life Scale scores. If sufficient homogeneity exists among included studies, the findings will be pooled using a traditional pairwise and network meta-analysis. The risk of bias in randomised control trials will be evaluated using the Cochrane Risk of Bias Tool 2.0. The Grading of Recommendations, Assessment, Development, and Evaluation approach will be used to report the certainty of evidence. ETHICS AND DISSEMINATION: This systematic review will not involve direct contact with human subjects. The findings of this review will be published in a peer-reviewed journal. They will give healthcare providers a better awareness of the optimal analgesic medication for pain treatment in non-severe, acute pancreatitis.

Pancreatic quantitative sensory testing to predict treatment response of endoscopic therapy or surgery for painful chronic pancreatitis with pancreatic duct obstruction: study protocol for an observational clinical trial.

INTRODUCTION: Treatment for abdominal pain in patients with chronic pancreatitis (CP) remains challenging in the setting of central nervous system sensitisation, a phenomenon of remodelling and neuronal hyperexcitability resulting from persistent pain stimuli. This is suspected to render affected individuals less likely to respond to conventional therapies. Endotherapy or surgical decompression is offered to patients with pancreatic duct obstruction. However, the response to treatment is unpredictable. Pancreatic quantitative sensory testing (P-QST), an investigative technique of standardised stimulations to test the pain system in CP, has been used for phenotyping patients into three mutually exclusive groups: no central sensitisation, segmental sensitisation (pancreatic viscerotome) and widespread hyperalgesia suggestive of supraspinal central sensitisation. We will test the predictive capability of the pretreatment P-QST phenotype to predict the likelihood of pain improvement following invasive treatment for painful CP. METHODS AND ANALYSIS: This observational clinical trial will enrol 150 patients from the University of Pittsburgh, Johns Hopkins and Indiana University. Participants will undergo pretreatment phenotyping with P-QST. Treatment will be pancreatic endotherapy or surgery for clearance of painful pancreatic duct obstruction. PRIMARY OUTCOME: average pain score over the preceding 7 days measured by Numeric Rating Scale at 6 months postintervention. Secondary outcomes will include changes in opioid use during follow-up, and patient-reported outcomes in pain and quality of life at 3, 6 and 12 months after the intervention. Exploratory outcomes will include creation of a model for individualised prediction of response to invasive treatment. ETHICS AND DISSEMINATION: The trial will evaluate the ability of P-QST to predict response to invasive treatment for painful CP and develop a predictive model for individualised prediction of treatment response for widespread use. This trial was approved by the University of Pittsburgh Institutional Review Board. Data and results will be reported and disseminated in conjunction with National Institutes of Health policies. TRIAL REGISTRATION NUMBER: NCT04996628.

Interventions for Pancreatitis-New Approaches, Knowledge Gaps, and Research Opportunities: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases Workshop.

ABSTRACT: There exists no cure for acute, recurrent acute or chronic pancreatitis and treatments to date have been focused on managing symptoms. A recent workshop held by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) focused on interventions that might disrupt or perhaps even reverse the natural course of this heterogenous disease, aiming to identify knowledge gaps and research opportunities that might inform future funding initiatives for NIDDK. The breadth and variety of identified active or planned clinical trials traverses the spectrum of the disease and was conceptually grouped for the workshop into behavioral, nutritional, pharmacologic and biologic, and mechanical interventions. Cognitive and other behavioral therapies are proven interventions for pain and addiction, but barriers exist to their use. Whilst a disease specific instrument quantifying pain is now validated, an equivalent is lacking for nutrition - and both face challenges in ease and frequency of administration. Multiple pharmacologic agents hold promise. Ongoing development of Patient Reported Outcome (PRO) measurements can satisfy Investigative New Drug (IND) regulatory assessments. Despite multiple randomized clinical trials demonstrating benefit, great uncertainty remains regarding patient selection, timing of intervention, and type of mechanical intervention (endoscopic versus surgery). Challenges and opportunities to establish beneficial interventions for patients were identified.

Alterations in exocrine pancreatic function after acute pancreatitis.

Exocrine pancreatic dysfunction (EPD) is a malabsorptive complication of pancreatic disorders that can lead to a host of symptoms ranging from flatulence to diarrhea and contribute to weight loss and metabolic bone disease. It is increasingly recognized to occur after acute pancreatitis (AP), including episodes with mild severity. The risk of developing EPD after AP is influenced by a range of factors, including the degree of acinar cell destruction and inflammation during AP, and persistent structural derangements following AP. In this article, we discuss the epidemiology, pathophysiology, and clinical management of EPD after AP while highlighting key knowledge gaps.

Effect of low- versus high-dose 4-factor prothrombin complex concentrate in factor Xa inhibitor-associated bleeding: A qualitative systematic review.

DISCLAIMER: In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. PURPOSE: The purpose of this review is to evaluate current literature on the treatment of factor Xa inhibitor-associated bleeds with 4-factor prothrombin complex concentrate (4F-PCC), with a focus on the effect of low versus high dosing of 4F-PCC on hemostatic efficacy and safety outcomes. SUMMARY: A search of PubMed and EBSCOhost was performed to identify studies evaluating patients with a factor Xa inhibitor-bleed treated with 4F-PCC at either low or high doses. Studies of patients receiving alternative reversal agents such as fresh frozen plasma and andexanet alfa or where no comparator group was evaluated were excluded from the analysis. To assess the effect of these 4F-PCC dosing strategies, the primary outcome of interest was hemostatic efficacy. Four studies meeting inclusion criteria were included in this review. In each of the included studies, similar rates of hemostatic efficacy, hospital mortality, and venous thromboembolism were observed in the low- and high-dose cohorts. CONCLUSION: These results suggest low- and high-dose 4F-PPC may confer similar clinical effectiveness and safety; however, these findings should be evaluated and confirmed with future prospective studies.

MicroCT illuminates the unique morphology of Shiinoidae (Copepoda: Cyclopoida), an unusual group of fish parasites.

The copepod family Shiinoidae Cressey, 1975 currently comprises nine species of teleost parasites with unusual morphology and a unique attachment mechanism. Female shiinoids possess greatly enlarged antennae that oppose a rostrum, an elongate outgrowth of cuticle that originates between the antennules. The antennae form a moveable clasp against the rostrum which they use to attach to their host. In this study, we use micro-computed tomography (microCT) to examine specimens of Shiinoa inauris Cressey, 1975 in situ attached to host tissue in order to characterize the functional morphology and specific muscles involved in this novel mode of attachment and to resolve uncertainty regarding the segmental composition of the regions of the body. We review the host and locality data for all reports of shiinoids, revise the generic diagnoses for both constituent genera Shiinoa Kabata, 1968 and Parashiinoa West, 1986, transfer Shiinoa rostrata Balaraman, Prabha & Pillai, 1984 to Parashiinoa as Parashiinoa rostrata (Balaraman, Prabha & Pillai, 1984) n. comb., and present keys to the females and males of both genera.

Recent advances in the understanding and management of chronic pancreatitis pain.

Abdominal pain is the most common symptom of chronic pancreatitis (CP) and is often debilitating for patients and very difficult to treat. To date, there exists no cure for the disease. Treatment strategies focus on symptom management and on mitigation of disease progression by reducing toxin exposure and avoiding recurrent inflammatory events. Traditional treatment protocols start with medical management followed by consideration of procedural or surgical intervention on selected patients with severe and persistent pain. The incorporation of adjuvant therapies to treat comorbidities including psychiatric disorders, exocrine pancreatic insufficiency, mineral bone disease, frailty, and malnutrition, are in its early stages. Recent clinical studies and animal models have been designed to improve investigation into the pathophysiology of CP pain, as well as to improve pain management. Despite the array of tools available, many therapeutic options for the management of CP pain provide incomplete relief. There still remains much to discover about the neural regulation of pancreas-related pain. In this review, we will discuss research from the last 5 years that has provided new insights into novel methods of pain phenotyping and the pathophysiology of CP pain. These discoveries have led to improvements in patient selection for optimization of outcomes for both medical and procedural management, and identification of potential future therapies.

Clinical diagnosis of psychiatric comorbidities, performance of screening tests and pattern of psychotropic medication use in patients with chronic pancreatitis.

BACKGROUND: Psychiatric comorbidity measured by screening instruments is common in patients with chronic pancreatitis (CP) but whether this accurately reflects clinical diagnosis of psychiatric comorbidity is unknown and the prevalence of psychotropic medication prescription in CP remains largely unexplored. METHODS: Adult patients (≥18 years) with definite CP were enrolled and completed the Hospital Anxiety and Depression Scale (HADS). Demographics, clinical characteristics and medications were retrieved from case report forms and the electronic health record (EHR). Clinical diagnosis of depression or anxiety was determined by presence of ICD-10 code or inclusion in the patient's EHR problem list or treatment plan. Comparisons were made between patients with and without clinical psychiatric comorbidity. RESULTS: Total of 81 patients (48, 59.3% male; mean age 57.6 ± 14.3 years) were included. Clinical diagnoses of anxiety and depression were each noted in 47 (58%) patients, with overlap in 42 (51.9%). Compared to clinical diagnoses, the sensitivity and specificity of a positive screen for anxiety (HADS >7) were 76.6% and 91.2%; for depression 55.3% and 88.2%. Patients with anxiety and/or depression were more frequently female (51.9% v 20.7%), younger (53.6 v 64.9 years), and had alcohol etiology (51.9% v 27.6%) (all p < 0.01). In those with psychiatric comorbidity, 42 (80.8%) were prescribed psychotropic medication, most commonly gabapentinoid (24, 57.1%), selective serotonin reuptake inhibitor (n = 22, 52.4%) or benzodiazepine (n = 20, 47.6%). CONCLUSIONS: Psychiatric comorbidities are common among CP patients and many receive psychotropic medications. Further studies are needed to evaluate the impact of these medications on CP symptoms.

Psychosocial interventions for ovarian cancer survivors: A systematic review.

OBJECTIVES: Ovarian cancer survivorship is complex and is associated with greater symptom burden, fear of reoccurrence, sexual dysfunction, lower quality of life and heightened existential distress in contrast to other cancers. This systematic review aimed to investigate the effectiveness for, and perspective of, psychosocial interventions encompassing psychological, social, and emotional support, tailored to, or involving ovarian cancer survivors at all stages of disease. METHODS: Adhering to the PRISMA-SR statement guidelines, a systematic search was conducted across PsycINFO, MEDLINE, Embase, Emcare, CINAHL, Scopus, Cochrane Library databases, Google, and Google Scholar. Two reviewers independently undertook a two-stage screening process. The Mixed Methods Appraisal Tool was utilised to assess the methodological quality of included studies. Data were extracted using customised data extraction tools and narratively synthesised. RESULTS: Thirteen studies were included in this review. Generally positive effects of psychosocial interventions were observed across a range of outcome domains (meaning enhancing, cognitive, social, emotional, and cancer-specific). However, the characteristics of interventions and outcome measures varied across studies. Psychoeducational interventions were identified as the most common psychosocial approach, while Acceptance and Commitment Therapy showed promise in addressing the disease's high symptom burden. Women's perspectives of psychosocial interventions were described as "useful" and promoted positive self-regard. CONCLUSION: While the evidence base largely support positive effects of psychosocial interventions for ovarian cancer survivors, this finding is constrained by heterogeneity of interventions and modest gains. Future research may explore the standardisation of psychosocial interventions for this demographic, investigating its effects on less explored but prevalent concerns among ovarian cancer survivors such as fear of cancer recurrence and sexual dysfunction.

Baseline soil-transmitted helminth and schistosome infection in the Geshiyaro project, Ethiopia: A unique transmission interruption project using biometric fingerprinting for longitudinal individual analysis.

BACKGROUND: The Geshiyaro project aims to assess the feasibility of interrupting transmission of soil-transmitted helminths (STH) and schistosome (SCH) infection in the Wolaita zone of southern Ethiopia through high coverage community-wide mass drug administration (MDA), in combination with improved water, sanitation, and hygiene services and behaviour change communication delivered through the existing health care infrastructure. To accurately measure treatment coverage a population census was conducted enrolling individuals with biometric fingerprinting and barcoded ID cards. This paper details the baseline census and parasitology surveys conducted before the start of any interventions. METHODS: The census was conducted in five of the 15 Wolaita districts between October 2018 and December 2019, enrolling all consenting participants from every household. Simultaneously, a cross-sectional parasitology survey was conducted in 130 out of 361 randomly selected communities from all 15 districts, with 100 individuals across all age groups (infant to adult) per community providing stool and urine for analysis by duplicate Kato-Katz and a point-of-care circulating cathodic antigen (POC-CCA) to test for Schistosoma mansoni and STH, and microhaematuria and urine filtration for Schistosoma haematobium. Of the 130 communities, 30 were randomly selected for annual, longitudinal parasitological monitoring, with 150 randomly selected individuals from infant to adult providing two days of stool and urine samples for analysis by the same diagnostic tests per community. RESULTS: In total 97,919 households participated in the baseline census enrolling 466,071 individuals, with parasitological data obtained from 10,785 people. At baseline, 15.5% were infected with at least one STH species, with Ascaris lumbricoides (9.5%), followed by hookworm (7.2%) and Trichuris trichiura (1.8%). Substantial heterogeneity in STH prevalence was observed between communities ranging from 0% to 61% where most infections were low intensity. Schistosoma mansoni infection was the dominant schistosome infection (0.85% by Kato-Katz and 13.3% by POC-CCA trace negative and 21.5% trace positive), with few Schistosoma haematobium infections identified (2.77% haematuria positive and 0.13% positive by urine filtration). CONCLUSIONS: While the national control program in Ethiopia has made good progress in reducing prevalence of STH and SCH in Wolaita since it was launched in 2015, there remain areas of persistent infection suggesting the existence of environmental or behavioural risk factors that contribute to ongoing transmission. This project aims to identify the most efficient intervention strategies to reduce community burden and reach interruption of transmission.

Incident diabetes following acute pancreatitis in a multicenter prospective observational cohort.

Diabetes mellitus following an episode of acute pancreatitis (AP) is an increasingly discussed complication, but there are sparse prospective data on the incidence and risk factors. We evaluated data from a prospective, multicenter observational cohort study that enrolled adults hospitalized with AP between 2017 and 2021 and followed them for one year. Ninety-eight participants who completed 12-month follow-up were included in this analysis. Diabetes status was assessed using a combination of measured glycated hemoglobin (HbA1c) at predetermined time intervals or physician diagnosis. In 68 participants without diabetes at enrollment, the cumulative incidence of new-onset diabetes was 4.4 % (n = 3) at 3 months and 10.3 % (n = 7) at 12 months. No differences were observed in demographic or pancreatitis-related characteristics between those who did versus did not develop diabetes, in part due to small sample size. In summary, new-onset diabetes was identified in approximately 10 % within one year after an episode of AP. Larger prospective studies are needed to further define the incidence, risk factors, and mechanisms of diabetes and pre-diabetes following AP. NCT03063398.

Progress from morbidity control to elimination as a public health problem of schistosomiasis and the status of soil-transmitted helminth infection in Togo: a second impact assessment after ten rounds of mass drug administration.

BACKGROUND: Due to the burden of schistosomiasis (SCH) and soil-transmitted helminths (STH), Togo Ministry of Health launched a program for Preventive Chemotherapy Neglected Tropical Diseases (PC-NTDs) in 2009, initiating integrated mass drug administration (MDA) the following year for the three PC-NTDs: SCH, STH and onchocerciasis. Significant reduction of infection across the country was noted in 2015 during the first impact assessment, following 5 years of high-coverage MDA implemented at the sub-district level for SCH and district level for STH. After another 5 years of effective MDA, a second survey was conducted in 2021 to re-evaluate the situation of SCH and STH. METHODS: A cross-section of school-aged children was taken across ten districts of Togo. A total of 302 schools in 92 sub-districts were sampled, with 24 school-aged children per school resulting in 7248 children surveyed. Urine samples were tested by haemastix® for Schistosoma haematobium, with urine filtration for the presence of eggs conducted on haematuria-positive samples. Stool samples were collected in a subset of 34 sub-districts in seven out of the ten surveyed districts, where STH and Schistosoma mansoni endemicity was high during the 2015 impact assessment. Duplicate (two) Kato-Katz analysis was performed for each stool sample. Sociodemographic and school-level water, sanitation and hygiene information was also collected. RESULTS: Overall, SCH prevalence was 5.90% (95% CI: 5.4-6.5), with 5.09% (95% CI: 4.64-5.67) for S. haematobium and 2.56% (95% CI: 1.98-3.29) for S. mansoni. STH prevalence was 19.7% (95% CI: 18.2-21.4), with 19.6% (95% CI: 18.1-21.3) hookworm, 0.08% (95% CI: 2.2-5.8) Trichuris trichiura and 0.04% (95% CI: 0.01-0.33) Ascaris lumbricoides. Compared to baseline, a significant reduction in both SCH (22.2% to 5.90%) and STH (29.2% t0 19.7%) prevalence was observed. Children aged 5-9 years were less infected than older peers aged 10-14 years: 4.76% vs. 7.53% (P < 0.01) for SCH and 17.2% vs. 23.0% (P < 0.01) for STH. CONCLUSIONS: After 10 years of high coverage integrated MDA, Togo has achieved low prevalence SCH infection through the sub-district MDA implementation with considerable infection heterogeneity within sub-districts. As STH infection has not reached a level where the infections are not a public health problem, the sub-district treatment strategy could also be adopted in addition to improvement of treatment coverage among preschool age children and hygiene and sanitation practices.

Serum Biomarkers of Nociceptive and Neuropathic Pain in Chronic Pancreatitis.

Debilitating abdominal pain is a common symptom affecting most patients with chronic pancreatitis (CP). There are multiple underlying mechanisms that contribute to CP-related pain, which makes successful treatment difficult. The identification of biomarkers for subtypes of pain could provide viable targets for nonopioid interventions and the development of mechanistic approaches to pain management in CP. Nineteen inflammation- and nociception-associated proteins were measured in serum collected from 358 subjects with definite CP enrolled in PROspective Evaluation of Chronic Pancreatitis for EpidEmiologic and Translational StuDies, a prospective observational study of pancreatitis in US adult subjects. First, serum levels of putative biomarkers were compared between CP subjects with and without pain. Only platelet-derived growth factor B (PDGF-B) stood out, with levels significantly higher in the CP pain group as compared to subjects with no pain. Subjects with pain were then stratified into 4 pain subtypes (Neuropathic, Nociceptive, Mixed, and Unclassified). A comparison of putative biomarker concentration among 5 groups (no pain and 4 pain subtypes) identified unique proteins that were correlated with pain subtypes. Serum transforming growth factor beta 1 (TGFß1) level was significantly higher in the Nociceptive pain group compared to the No pain group, suggesting that TGFß1 may be a biomarker for nociceptive pain. The Neuropathic pain only group was too small to detect statistical differences. However, glycoprotein 130 (GP130), a coreceptor for interleukin 6, was significantly higher in the Mixed pain group compared to the groups lacking a neuropathic pain component. These data suggest that GP130 may be a biomarker for neuropathic pain in CP. PERSPECTIVE: Serum TGFß1 and GP130 may be biomarkers for nociceptive and neuropathic CP pain, respectively. Preclinical data suggest inhibiting TGFß1 or GP130 reduces CP pain in rodent models, indicating that additional translational and clinical studies may be warranted to develop a precision medicine approach to the management of pain in CP.

Individual longitudinal compliance to neglected tropical disease mass drug administration programmes, a systematic review.

Repeated distribution of preventative chemotherapy (PC) by mass drug administration forms the mainstay of transmission control for five of the 20 recognised neglected tropical diseases (NTDs); soil-transmitted helminths, schistosomiasis, lymphatic filariasis, onchocerciasis and trachoma. The efficiency of such programmes is reliant upon participants swallowing the offered treatment consistently at each round. This is measured by compliance, defined as the proportion of eligible participants swallowing treatment. Individually linked longitudinal compliance data is important for assessing the potential impact of MDA-based control programmes, yet this accurate monitoring is rarely implemented in those for NTDs. Longitudinal compliance data reported by control programmes globally for the five (PC)-NTDs since 2016 is examined, focusing on key associations of compliance with age and gender. PubMed and Web of Science was searched in January 2022 for articles written in English and Spanish, and the subsequent extraction adhered to PRISMA guidelines. Study title screening was aided by Rayyan, a machine learning software package. Studies were considered for inclusion if primary compliance data was recorded for more than one time point, in a population larger than 100 participants. All data analysis was conducted in R. A total of 89 studies were identified containing compliance data, 57 were longitudinal studies, of which 25 reported individually linked data reported by varying methods. The association of increasing age with the degree of systematic treatment was commonly reported. The review is limited by the paucity of data published on this topic. The varying and overlapping terminologies used to describe coverage (receiving treatment) and compliance (swallowing treatment) is reviewed. Consequently, it is recommended that WHO considers clearly defining the terms for coverage, compliance, and longitudinal compliance which are currently contradictory across their NTD treatment guidelines. This review is registered with PROSPERO (number: CRD42022301991).

Relationship of circulating levels of long-chain fatty acids to persistent organ failure in acute pancreatitis.

During acute pancreatitis (AP), free fatty acids (FFAs) are liberated from circulating triglycerides (TG) and injured adipocytes by pancreatic lipase. Circulating FFAs have been suspected as a source of systemic lipotoxicity in AP. However, assessment of FFAs is difficult and time-consuming, and little is known about relative levels of FFAs between patients with different severities of AP and controls. This study's aims were to assess early circulating levels of FFAs, (both saturated and unsaturated) in patients with AP vs. controls, and associations between FFA levels and AP severity. Serum samples from patients with AP were collected at enrollment (day 1 of hospital stay); serum samples were also collected from controls. FFAs including palmitic, palmitoleic, stearic, oleic, and linoleic acid were extracted and quantitated using gas chromatography separation. Severity of AP was determined by Revised Atlanta Classification. Differences in FFA levels and percentages of total FFAs were assessed between patients with AP and controls and patients with AP of different severity grades. A total of 93 patients with AP (48 female, 52%) and 29 controls (20 female, 69%) were enrolled. Of the patients with AP, 74 had mild/moderate and 19 had severe AP. Serum levels of all FFAs except stearic acid were significantly higher in patients with AP compared with controls. A strong and independent association between elevated palmitoleic acid levels and severe AP was found. Serum unsaturated FFA levels, specifically palmitoleic acid, appear to correlate with severe AP. These findings have potential clinical implications for targeted AP therapies.NEW & NOTEWORTHY Drivers of the inflammatory response in acute pancreatitis remain incompletely understood. Unsaturated fatty acids, specifically palmitoleic, appear to have an association with more severe acute pancreatitis. This finding presents a new clinical understanding of fatty acid toxicity and highlights a potential future target for treatment in severe acute pancreatitis.

Pancreatic Malakoplakia: A Rare Pathology Associated With Acute Pancreatitis.

Malakoplakia is a rare granulomatous tumor-like inflammatory condition, most frequently involving the genitourinary system and occurring in immunosuppressed patients. The gastrointestinal tract is the second most common site, where it is usually seen involving the colon. We report a case of malakoplakia presenting as a pancreatic mass. Imaging showed soft tissue along the pancreatic tail/greater curvature concerning for infiltrating tumor, but endoscopic ultrasound with biopsy showed malakoplakia. Our case discusses malakoplakia at an uncommon site, which was appropriately treated with antibiotics.
