Self-embedding behavior: radiologic management of self-inserted soft-tissue foreign bodies

Preputial advancement flap for delayed urethrocutaneous fistula of the glans following urethral insertion of an 'AAA' battery

INTRODUCTION

Foreign body insertion associated with sexual gratification is known as polyembolokoilomania. Following removal of the foreign body, long-term complications are infrequently seen. Whilst conservative and endoscopic approaches usually suffice, in extreme cases open surgical approaches are required. We describe an unusual case of polyembolokoilomania in a 25-year-old male involving a single 'AAA' battery who developed a urethrocutaneous fistula requiring delayed reconstructive surgery.

CASE PRESENTATION

Following an initial successful open extraction of an 'AAA' battery from the mid penile urethra the patient developed a delayed urethrocutaenous fistula of the glans. This was managed using a single stage closure with a preputial graft on its vascular pedicle thereby preserving the foreskin and avoiding a buccal graft. No intra-operative or post-operative complications occurred with a catheter left in situ for 2 weeks. Formal histology confirmed a foreign body type reaction. Following outpatient review successful cosmetic, functional, and sexual outcomes were recorded with questionnaires and medical photography.

CONCLUSION

Preputial advancement flap with foreskin preservation for distal urethrocutaenous fistula is a successful method of treating delayed urethrocutaenous fistula of the distal urethra in cases of polyembolokoilomania.

Management of Incisional Self-Harm of the Upper Limb: A Systematic Review

Background

The incidence of incisional self-harm of the upper limbs is increasing, and recurrence rates are high. It is not known whether different wound treatment strategies (dressings only vs. surgery) or the operative setting (main theatre vs. non-main theatre) affect wound or mental health-related outcomes.

Methods

Four electronic databases (Ovid MEDLINE, OVID EMBASE, PsycINFO and CENTRAL) were searched from inception to 14/09/2021 for studies which describe the management of incisional self-harm wounds of the upper limb(s) in adults and children. Dual-author screening and data extraction were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

In total, 19 studies (1477 patients) were included. Overall, the evidence was limited by a paucity of comparative data on wound management strategy and setting, and poor-quality outcome reporting. Only four studies clearly identified the operative setting for definitive wound management (two in main operating theatres, one in the emergency department and one using both settings, depending on injury severity). Few studies inconsistently reported surgical outcomes (n=9) or mental health outcomes (n=4), hindering evidence synthesis.

Conclusion

Further investigation is needed to determine the most cost-effective management strategies and settings for these injuries.

Radioactive seed localization of foreign body

Radioactive seed localization is a method widely used within breast cancer treatment. This case represents a 43-year-old male patient with a foreign body in his left axilla. We used radioactive seed localization for marking the foreign body, which made the subsequent surgery possible, quick, and minimal invasive.

Foreign body removal with the assistance of ultrasound guidance and methylene blue staining in children-a cohort study

BACKGROUND

Soft tissue foreign bodies (FBs) are very commonly observed in paediatric emergency departments. Not all FBs can be removed effectively, even via open surgery and image intensifier guidance. In the current study, we evaluated the efficiency of FB removal with the assistance of ultrasound (US) and methylene blue (MB) staining.

METHODS

We enrolled 80 patients at our clinical center between May 2016 and December 2020. Eleven patients were operated upon with the assistance of US guidance and MB and were defined as group A; the other 69 patients were defined as group B. For the patients in group A, US was first used to locate the FB; MB was then injected next to the FB. Open surgery was subsequently performed. For group B, the FBs were removed by conventional methods. The surgical outcomes were evaluated according to surgical duration, incision infection rates, radiograph exposure times, and FB residue rates.

RESULTS

The average surgery time for group A was 0.35 ± 0.10 hours; the corresponding time was 0.49 ± 0.50 hours in group B and there was a significant difference between the groups (p = 0.032). The radiograph exposure times were 1.33 ± 0.34 in group A and 4.65 ± 1.81 times in group B (p = 0.021).

CONCLUSIONS

This study demonstrates that assistance of US and MB staining is a more efficient approach compared with traditional methods for FB removal, and this surgical method can be used effectively for FB removal in children.

Soft tissue foreign bodies: A training manual for sonographic diagnosis and guided removal

Sonography provides excellent detection, localization, and characterization of soft-tissue foreign bodies. Ultrasound guided foreign body removal is a safe and highly successful minimally invasive procedure that facilitates effective treatment and avoidance of complications in patients with soft tissue foreign bodies. Focused laboratory training is critical to successful implementation of a sonographic foreign body management practice.

Soft Tissue Foreign Body: Utility of High Resolution Ultrasonography

INTRODUCTION

Minor percentage of wooden foreign bodies is radio-opaque. High Resolution Ultrasonography (HRUSG) though existing is sparsely used as a primary imaging modality for diagnosis and localization of retained foreign body.

AIM

To evaluate the diagnostic accuracy of High Resolution Ultrasonography (HRUSG) in diagnoses and localization of retained foreign body.

MATERIALS AND METHODS

A prospective study with registered 46 patients with history of foreign body injury which were initially imaged with conventional radiography was enrolled. Later patients were subjected for high resolution USG of the diseased part with a linear transducer. Surface marking was done for all subjects to assist the surgical exploration. Ultrasound findings were correlated with surgical exploration and histopathological findings.

RESULTS

Out of 46 patients, forty one showed foreign body with foreign body inflammatory reaction in the form of abscess and/or granulation tissue on high resolution ultrasonography. No foreign body was detected in five patients but they showed focal hypoechogenicity which represented abscess and/or haematoma. On surgical exploration, two out of 41 patients did not reveal foreign body where as rest were found to have foreign body with foreign body inflammatory reaction. Sensitivity and negative predictive value of the current study is 100%.

CONCLUSION

High resolution USG is not only an efficient modality in diagnosing and localizing the foreign body in soft tissue, but can also be utilized for guiding the foreign body removal.

Self-Embedding Behavior in Adults: A Report of Two Cases and a Systematic Review

Self-embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty-two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two-thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis.

Perceptions of the Functions of Nonsuicidal Self-Injury in a College Sample

BACKGROUND

Rates of nonsuicidal self-injury (NSSI) are particularly high on college campuses. Commonly endorsed reasons for NSSI include interpersonal (e.g., seeking support) and intrapersonal (e.g., affect regulation) functions.

AIMS

This study compared college students with and without a history of NSSI on their views of NSSI functions in order to inform gatekeeper intervention/prevention programs targeting NSSI.

METHOD

The Inventory of Statements About Self-Injury, which assessed NSSI behavior and functions of NSSI, was completed by 367 college students (73% female, 95% white).

RESULTS

Ninety-eight participants endorsed lifetime moderate/severe NSSI, 109 endorsed minor NSSI, and 160 denied any history of NSSI. Noninjuring participants' views of NSSI functions were compared with the views held by participants with histories of NSSI. The groups did not differ in their views of the relevance of intrapersonal functions, although noninjuring individuals appeared to stress some interpersonal factors (e.g., influence) slightly more than individuals with a history of NSSI did.

CONCLUSION

These results suggest that college students generally hold similar perceptions of the functions of NSSI. Our findings suggest intervention/prevention efforts may consider broadening the selection of gatekeepers (e.g., peers with no history of NSSI) in schools and colleges to identify at-risk students and encourage help-seeking behaviors.

Nonsuicidal self-injury-related foreign bodies in the emergency department

Nonsuicidal self-injury is a common cause of foreign bodies encountered in emergency departments, resulting in significant morbidity, mortality, and economic costs. We review the role of imaging and frequent imaging findings in nonsuicidal self-injury, illustrated by case examples from a level 1 trauma center with dedicated jail and psychiatric wards in a major US metropolitan teaching hospital.

Ultrasound-guided needle localization to aid foreign body removal in pediatric patients

Patients with podiatric foreign body injury commonly present to the emergency department. Often, the foreign object cannot be easily located or removed, and radiographs are frequently obtained to aid in localization. In cases requiring tissue dissection to remove the foreign bodies, accurate localization is required for safe removal of small and difficult to visualize bodies. We present 2 pediatric cases in which an ultrasound-guided needle localization technique was used to facilitate successful removal of small, difficult to visualize foreign bodies from the plantar foot. Ultrasound-guided needle localization reduced the required incision length and depth and helped to minimize the risk of damage to surrounding tissue.

Ultrasound localization of a tunneled leech beneath a microvascular scalp reconstruction: A case report

Medicinal leech therapy is a common adjuvant modality used to treat venous congestion following threatened microvascular anastomosis. Migration and tunneling of a leech beneath a surgical reconstruction is a rare event that is seldom mentioned in the literature and worthy of further discussion. We present a rectus abdominus myocutaneous free tissue transfer that was used to cover a large alloplastic cranioplasty following resection of a previously radiated skull base malignant meningioma. The flap became congested postoperatively and required leech therapy after surgical salvage. Three days after flap salvage, the subject was once again brought back to the operating room for surgical exploration when a leech was witnessed to migrate beneath the threatened free flap. Duplex ultrasound was used intra-operatively to localize the leech 12 cm from its bite and assist with its successful removal. Tunneling of the leech beneath the flap is a rare complication, and localization underneath a myofascial or myocutaneous flap may be difficult. Duplex ultrasound is a simple and reliable method to localize the leech and allow for its removal through a minimal access incision.

Ultrasound-guided musculoskeletal procedures in children

Ultrasound is an excellent tool to evaluate many pediatric musculoskeletal conditions. It may be used for both diagnosis and for guidance for therapeutic procedures. With US, the radiologist can readily evaluate the contralateral side for comparison. No sedation is typically required and ionizing radiation is avoided. Real-time information is obtained with US and the portability of US allows for the performance of bedside interventions in children who cannot be transported or are clinically unstable. Limitations of US compared with MRI and CT include limited field of view, inability to evaluate the bone marrow and user dependence of image and exam quality. In this article, we discuss common US-guided musculoskeletal procedures in children, including hip aspiration, joint injection, soft-tissue biopsy and foreign body removal.

Value of 3-dimensional CT virtual anatomy imaging in complex foreign body retrieval from soft tissues

Objective

To investigate the value of 3-dimensional (3D) CT virtual anatomy imaging (VAI) in the complex foreign body (FB) retrieval of the soft tissues.

Materials and Methods

Four hundred and seventy-five patients with radiopaque FB(s) diagnosed by radiograph underwent contrast-enhanced 3D CT examination. VAI was reconstructed by volume-rendering opacity software, by sliding down the lowest threshold from -600 to 100 HU. The imaging was grouped into three groups: A (axial and multi-planar reformation [MPR] images), B (standard 3D imaging with axial and MPR images), and C (VAI with axial and MPR images). They were analyzed to reveal the type, size, number, location, complications, and the interventional removability of the object, with the comparisons in the management and clinical outcomes on the patient follow-up studies. The data were subjected to chi-square tests, with p value < 0.05 indicating significant statistical difference.

Results

The FB shape, size, number, site distribution and vessels around FB, as well as the FB-associated vascular complications and the FB interventional removability were assessed more accurately in Group C than in Group B or Group A (p < 0.005). There was no significant difference in disclosing the type and depth of the FB among the three groups (p > 0.75). On the basis of the 3D CT, especially the enhanced 3D CT VAI, the followings were processed: the recommendation of interventional removal in 286 (60.47%) and non-intervention in 187 (39.53%) of the 473 patients with soft-tissue FB(s); in 352 (56.50%) of the 623 radiopaque FBs patients, 258 (54.55%) patients accurately detected on 3D CT and the successful removal by intervention (343 FBs) or surgery (9 FBs) without any sequela; and 215 (45.45%) patients with 271 FBs lost in the follow-up, with their departure from the hospital.

Conclusion

The 3D CT, especially 3D enhanced CT VAI, has great incremental value in further diagnosis and management of complex FB extraction from soft tissues.

Determination of optimal imaging mode for ultrasonographic detection of subdermal contraceptive rods: comparison of spatial compound, conventional, and tissue harmonic imaging methods

Objective

To determine which mode of ultrasonography (US), among the conventional, spatial compound, and tissue-harmonic methods, exhibits the best performance for the detection of Implanon® with respect to generation of posterior acoustic shadowing (PAS).

Materials and Methods

A total of 21 patients, referred for localization of impalpable Implanon®, underwent US, using the three modes with default settings (i.e., wide focal zone). Representative transverse images of the rods, according to each mode for all patients, were obtained. The resulting 63 images were reviewed by four observers. The observers provided a confidence score for the presence of PAS, using a five-point scale ranging from 1 (definitely absent) to 5 (definitely present), with scores of 4 or 5 for PAS being considered as detection. The average scores of PAS, obtained from the three different modes for each observer, were compared using one-way repeated measure ANOVA. The detection rates were compared using a weighted least square method.

Results

Statistically, the tissue harmonic mode was significantly superior to the other two modes, when comparing the average scores of PAS for all observers (p < 0.00-1). The detection rate was also highest for the tissue harmonic mode (p < 0.001).

Conclusion

Tissue harmonic mode in uS appears to be the most suitable in detecting subdermal contraceptive implant rods.

Ultrasound-assisted musculoskeletal procedures: A practical overview of current literature

Traditionally performed by a small group of highly trained specialists, bedside sonographic procedures involving the musculoskeletal system are often delayed despite the critical need for timely diagnosis and treatment. Due to this limitation, a need evolved for more portability and accessibility to allow performance of emergent musculoskeletal procedures by adequately trained non-radiology personnel. The emergence of ultrasound-assisted bedside techniques and increased availability of portable sonography provided such an opportunity in select clinical scenarios. This review summarizes the current literature describing common ultrasound-based musculoskeletal procedures. In-depth discussion of each ultrasound procedure including pertinent technical details, indications and contraindications is provided. Despite the limited amount of prospective, randomized data in this area, a substantial body of observational and retrospective evidence suggests potential benefits from the use of musculoskeletal bedside sonography.

Self-embedding behavior: a new primary care challenge

OBJECTIVE

The goal of this study was to define self-embedding behavior (SEB), develop a clinical profile of adolescents who engage in SEB, and emphasize the importance of rapid, targeted, and effective identification and intervention.

METHODS

As part of a retrospective study with a database evaluating 600 patients percutaneously treated for soft-tissue foreign body removal, adolescents were identified with self-embedded soft-tissue foreign bodies. We describe patients' gender, age, and psychiatric diagnoses; SEB age of onset, frequency, and self-reported reasons; and the number, type, location of, and removal technique for objects.

RESULTS

Eleven patients (9 females) who engaged in SEB were identified. Ten of the 11 patients were members of a group home or psychiatric facility at the time they engaged in SEB. All patients had previous and multiple psychiatric diagnoses. SEB mean age-of-onset was 16 years, and mean number of SEB episodes per patient was 1.9. The most common self-reported purpose for SEB was suicidal ideation (6 of 8 [75%]) versus nonsuicidal ideation (2 of 8 [25%]), with 3 cases lacking this documentation. The mean number of objects embedded in a single episode was 2.4, usually composed of metal and embedded in the arm. Seventy-six foreign bodies were percutaneously removed (using ultrasound or fluoroscopic guidance), including metal, glass, wood, plastic, graphite, and crayon.

CONCLUSIONS

SEB is an extreme form of self-injury requiring aggressive and timely interdisciplinary assessment and treatment. An understanding of SEB allows medical professionals to pursue rapid, targeted, and effective intervention to interrupt the cycle of self-harm and institute appropriate long-term therapy.
