Radiation proctitis-related lumbar spondylodiscitis due to Actinomyces odontolyticus: a rare finding

Lumbar spondylodiscitis due to radiation proctitis-related fistula is a rare finding in the literature. After having isolated Actinomyces odontolyticus, a rare finding in the osteomuscular system, we present one of such cases.A 75-year-old patient with a history of rectum adenocarcinoma, submitted to surgery and radiotherapy, presented himself in our emergency department with a 3-month history of lumbar pain radiating to both legs. Physical examination was compatible with cauda equina syndrome and subsequent investigation revealed L4–L5 spondylodiscitis. Despite a 6-month antibiotic therapy regimen, the symptoms recurred. Intravertebral disc biopsy revealed A. odontolyticus and directed antibiotic therapy was started. However, the symptoms recurred after a new 6-month antibiotic therapy regimen, this time with rectal purulent drainage. Additional study revealed two rectal fistulae. It was assumed those were caused by radiation proctitis and constituted the primary cause of spondylodiscitis. Laminectomy was performed with a satisfactory clinical response.

Surgical management of an extensive spinal epidural abscess: illustrative cases

BACKGROUNDExtensive spinal epidural abscesses (SEAs) occupying three or more spinal regions are rare. This study aimed to address the key dilemma of surgical treatment for holospinal epidural abscesses, i.e., to determine the required scope of surgery and minimize surgical trauma with adequate purulent drainage.OBSERVATIONSTwo patients with extensive SEAs were treated at the Neurosurgery Department of the Central Hospital of Ministry of Internal Affairs of Ukraine from 2018 to 2020. Both patients had a neurological deficit and general inflammatory response syndrome. Spinal magnetic resonance examinations were performed, showing that the first and second patients had extensive SEAs at T11/S1 and C2/L1, respectively. Both underwent minimally invasive abscess drainage via intra- and translaminar access at the most caudal point using an epidural silicone catheter in the cranial direction along the entire length of the abscess.LESSONSTo achieve the key goal of extensive SEA treatment, i.e., to prevent the development of a persistent neurological deficit, immediate effective spinal canal decompression should be performed. Access method and scope should meet the requirements of spinal canal decompression and purulent content aspiration to the greatest possible extent while inducing minimal trauma.

CRANIAL OSTEOMYELITIS AS A COMPLICATION OF FURUNCULAR MYIASIS

ABSTRACT Objective: To report the case of an infant with infrequent cranial osteomyelitis as a complication of furuncular myiasis. Case description: The patient was a 4-month-old male who presented to the emergency department with a nodular skull lesion with edema, tenderness, pain, and purulent drainage, as well as progress of the ulcerated lesion and evidence of larvae inside. Antibiotic treatment was initiated, and the patient was taken to the operating room to remove the larvae, but he had no symptomatic improvement. A skull radiograph was taken to visualize the osteolytic lesion, and a 3D computed tomography scan showed osteomyelitis of the external parietal surface. Antibiotic management readjustment continued for a total of six weeks, and a skin flap was used with clinical improvement. Comments: Myiasis is defined as the infestation of vertebrates with fly larvae. In mammals, larvae can feed on host tissue and cause a wide range of infestations depending on their location in the body. The cranial osteomyelitis as a complication of myiasis described in this report seems to be an exceptional case.

Clinical utility of a traditional score system for the evaluation of the peritoneal dialysis exit-site infection in a national multicentric cohort study

Introduction: Exit-site infection (ESI) is an important risk factor for peritonitis in patients under chronic peritoneal dialysis (PD). The International Society for Peritoneal Dialysis (ISPD) recommend its diagnosis as the presence of purulent drainage in the exit site (ES) but time-consuming scores using others skin signs are routinely used. Objective: To investigate the correlation between the diagnosis of ESI with a score based on five clinical signs obtained from ES inspection, and also if there are interaction with patient’s race. Methods: Multicenter and prospective cohort. We included adult patients from 122 clinics, incident on PD and with a 12-month stay in therapy. The event of interest was ESI, defined as purulent drainage. The clinical score used was composed of hyperemia, edema, pain, scab, and granuloma. Statistical analysis was performed using multilevel logistic regression model, likelihood test, and Cohen concordance analysis. Results: A total of 35,354 ES assessments were performed during the first year of dialysis in 3297 patients. There was a rate of 10.1 (9.1–11.2) episodes of ESI per 1000 patients/month. In patients with ESI, the prevalence of hyperemia was 55.9%, edema 67.3%, pain 31.8%, and scab 23.2%. The agreement with the score was 60.6% and showed differences according to the patient’s race, being 53.2% for African Americans descendants and 65.4% for others. The use of scales for the diagnosis of ESI does not add much information in addition to the presence of purulent secretion as currently recommended by the ISPD.

Interdigital Tinea: The Forerunner of Infectious Eczematoid Dermatitis

Infectious eczematoid dermatitis (IED) is defined as an acute, eczematous eruption that occurs secondary to autosensitization to purulent drainage from a primary infected site. The condition is believed to develop when bacterial products, most often the result of Staphylococcal or Streptococcal species, act as haptens and stimulate an immune response. IED typically manifests as a plaque with associated vesicles and pustules surrounding drainage from a central infectious source, or as oozing, erythema, crusting, and scaling spreading peripherally from a central infectious source. Management of IED includes both targeting the causative primary infection and suppressing the immune response producing a hypersensitivity reaction. This report details two cases. Case 1 describes a common presentation of tinea pedis. Case 2 is that of a 28 year-old-male who presented with an acute onset tender, pruritic, weeping rash after wearing boots for two straight days, and who was subsequently diagnosed and treated for IED.

Disseminated Coccidioidomycosis Presenting as Polyarticular Septic Arthritis: A Case Report

Coccidioidomycosis a fungal infection endemic to southwestern United States. It is caused by inhalation of spores of Coccidioides immitis. Sixty percent of infections are asymptomatic; the remaining 40% are primarily pulmonary disease. In <1% of infections, dissemination can occur. Dissemination usually affects those with impaired cellular immunity and pregnant women, and can involve bones, joints, meninges, and skin. We present the case of a 29-year-old Hispanic male who presented to the emergency department (ED) complaining of pain and swelling of right wrist and ankle as well as left knee for 2 months. He was referred to rheumatology clinic but returned to the ED as he developed spontaneous purulent drainage from his wrist. In the ED, an arthrocentesis of 2 of the joints showed total nucleated cells of 520 000/cm2 and 90 000/cm2 with 61% and 93% neutrophils, respectively. Fungal culture eventually grew Coccidioides immitis from his wrist and knee. Coccidioidomycosis complement fixation titer came back >1:512. Bone scan showed uptake of adjacent bones in the affected joints. Superimposed bacterial infection of the wrist complicated the treatment course and delayed the start of liposomal amphotericin B. Eventually patient received 12 weeks of intravenous liposomal amphotericin-B with slow clinical improvement and then switched to oral isavuconazonium for maintenance therapy. This case shows that although disseminated polyarthritis coccidioidomycosis is very rare, clinicians should keep the diagnosis of disseminated synovial coccidioidomycosis in mind in patients with risk factors.

Primary Myiasis in Surgical Wound of Mandible Symphisis Fracture

A 42 year old patient was referred to the Department of Oral and Maxillofacial Surgery of the Federal University of Uberlândia, for treatment of mandibular fractures (condyles and symphysis), a victim of a run over. The symphysis was surgically approached, using as surgical access the pre-existing laceration in the submental region. Five days after discharge, the patient returned with dehiscence of the wound and physical examination showed infestation by larvae in the symphysis. Mechanical removal and debridement were performed under local anesthesia, where plate exposure was noted. The patient underwent oral ivermectin therapy, intravenous antibiotic therapy and a thorough debridement was performed under general anesthesia due to the invasion of deep spaces in the supra-hyoid region. After 2 weeks, it presented with purulent drainage at the site. The miniplates were replaced by a 2.4 mm reconstruction plate and antibiotic therapy was maintained. Due to the social risk, the patient remained hospitalized for 45 days, when he was discharged with outpatient return, but did not attend the returns.

Necrotic Skin Infection by Sphingomonas Paucimobilis in Amazonia Region

Sphingomonas paucimobilis is an opportunist pathogen bacillus gram-negative aerobic with a rare occurrence. We present a case in an immunocompetent man successfully treated by surgical debridement, purulent drainage and with an associated course of antibiotics. A large necrotic infection, approximately 5 cm x 3 cm, in a 74-year-old man was identified. Empirical antibiotic therapy with ciprofloxacin 400mg EV 12/12 hours, associated with clindamycin 600mg EV 6/6 hours and pain control was done through dipyrone 1gr, tramadol 400 mg. Deep venous thrombosis was prevented through the prescription of enoxaparin 40mg subcutaneous once a day during hospitalization. The case was well illustrated with pictures throughout treatment. Complete healing was achieved after 90 days. Herein, we present a case of cutaneous contamination. The presented case is the third cutaneous contamination case reported in the literature and the first reported case in the Amazonia region in Brazil.

An Adult with a Remnant Urachus Anomaly Diagnosed in the Emergency Department

The urachus is a midline tubular structure that stretches from the apex of the bladder and connects to the umbilicus. Urachal remnants result from incomplete regression of the fetal urachus in infancy. We report the case of a 21-year-old male who presented to the emergency department with purulent drainage from his umbilicus in association with a chronic intermittent “pulling sensation” in the umbilicus and suprapubic areas. An infected urachal remnant was diagnosed and was treated with an oral antibiotic and ultimately with outpatient excision of the remnant. Such cases are rare but have the potential to progress to sepsis. In addition, chronic inflammation can lead to neoplastic transformation (adenocarcinoma). Urachal remnant infections can be considered in adults with umbilical purulent drainage. We propose that the “pulling sensation” described may be a clue to the diagnosis in some patients in which the urachal remnant is attached to the bladder and that the sensation was due to the mechanical connection between the bladder and the umbilicus. The sensation resolved postremoval status of the remnant. This does not appear to have been previously proposed in the literature.
