Fulltext Scedosporium apiospermum: A Rare Cause of Aggressive Orbital Apex Syndrome

Loh UL, Tai PY, Hussein A, A Qamarruddin F

Cureus, 2018 Dec 17;10(12):e3743.
PMID: 30800553 DOI: 10.7759/cureus.3743

Orbital apex syndrome (OAS) is a localized orbital cellulitis at the orbital apex that can cause vision loss from optic neuropathy and ophthalmoplegia involving multiple cranial nerves. Herein, we report a rare and rapidly progressive case of OAS secondary to fungal pansinusitis caused by Scedosporiumapiospermum in an immunocompromised patient following the extraction of abscessed teeth. A 48-year-old man with diabetes mellitus who had failed to adhere to his treatment presented with complaints of a right-sided headache and toothache for two weeks, with nausea and vomiting for two days prior to presentation. The patient was treated for septic shock secondary to the dental abscesses. Non-contrast brain computed tomography (CT) showed no significant intracranial abnormalities other than pansinusitis. Four days later, dental extraction was performed. The patient reported progressive painless blurring of the vision in his right eye following the dental extractions and was referred to the ophthalmology department. Subsequent examinations revealed decreased optic nerve function and ophthalmoplegia in his right eye and dental caries in the upper molars, with a mucopurulent discharge from the right sphenoid region. The clinical diagnosis was OAS. Pus near the orbital apex was drained surgically. Methicillin-resistant Staphylococcus aureus was isolated from the pus and a nasal swab. Tissue culture from the septal wall yielded S.apiospermum. The patient's condition deteriorated, despite intensive antibiotic and antifungal treatment and repeated surgical debridement. The disease progressed rapidly to his left eye. Sixty-seven days after the inital presentation, his visual acuity (VA) of both eyes was classified as no perception of light (NPL). The patient discharged himself from the hospital (at own risk discharge) and subsequently failed to attend a scheduled appointment in the ophthalmology clinic. If immunocompromised patients present with OAS, fungal infections should be ruled out. Prompt and aggressive treatment using a multidisciplinary approach is mandatory in cases of potentially life-threatening and vision-threatening fungal infections.

Antibiotic Irrigation: A Promising Unconventional Method for Facial Carbuncle

Ng JJ, Gendeh H, Ong HY, Gopalan S, Abdul Karaf JH

Cureus, 2021 Apr 27;13(4):e14710.
PMID: 34079672 DOI: 10.7759/cureus.14710

Carbuncle is conventionally treated with combinations of intravenous antibiotics and surgical intervention; be it saucerization or incision and drainage. Cosmesis outcome might be unfavorable following surgical intervention, especially when the facial region is involved. Skin grafting surgery may even be needed as a second-stage procedure for a larger wound. We reported a series of three facial carbuncles treated successfully with a new improvised method. Our method includes performing a stab incision prior to draining of pus, coupled with minimal wound debridement, followed by regular irrigation of the wound with antibiotics containing solution. Based on the three cases reported in this article, we conclude that this method is more superior as there is more skin preservation, better patient tolerance, shorter hospital stays, and favorable cosmesis outcome.

Fulltext A case report: Community-acquired Pseudomonas aeruginosa necrotizing fasciitis in a morbidly obese diabetic young man can be fatal

Mazlan MZ, Zainal Abidin H, Wan Hassan WMN, Nik Mohamad NA, Salmuna ZN, Ibrahim K, et al.

IDCases, 2020;22:e01001.
PMID: 33204633 DOI: 10.1016/j.idcr.2020.e01001

We present a case study of a 26-year-old morbidly obese man with a three-day history of right leg pain and swelling. The swelling was associated with low grade fever. He was alert and conscious upon presentation to the hospital. His physical examination showed gross swelling of the entire right lower limb with no systemic manifestations. There was no discharge and bullae from the swelling area of the leg. He had high blood sugar and was newly diagnosed with type 2 diabetes mellitus. He was diagnosed with necrotizing fasciitis. An intravenous imipenem-cilastatin 500 mg every 6 h together with clindamycin 900 mg every 8 h was started empirically. Extensive wound debridement was performed. The swab culture obtained intraoperatively grew Pseudomonas aeruginosa. He required an above knee amputation due to worsening infection despite wound debridement. Post-operatively, he developed acute kidney injury with severe metabolic acidosis, which required daily hemodialysis. However, the patient deteriorated due to septic shock with multi-organ failure, resulting in his death.

Facial carbuncle - a new method of conservative surgical management plus irrigation with antibiotic-containing solution

Ngui LX, Wong LS, Shashi G, Abu Bakar MN

J Laryngol Otol, 2017 Sep;131(9):830-833.
PMID: 28412984 DOI: 10.1017/S0022215117000834

OBJECTIVE: This paper reports on a non-conventional method for the management of facial carbuncles, highlighting its superiority over conventional surgical treatment in terms of cosmetic outcome and shorter duration of wound healing.
BACKGROUND: The mainstay of treatment for carbuncles involves the early administration of antibiotics in combination with surgical intervention. The conventional saucerisation, or incision and drainage, under normal circumstances results in moderate to large wounds, which may need secondary surgery such as skin grafting, resulting in a longer duration of wound healing and jeopardising cosmetic outcome.
CASE REPORTS: The reported three cases presented with extensive carbuncles over the chin, face and lips region. In addition to early commencement of intravenous antibiotics, the pus was drained, with minimal incision and conservative wound debridement, with the aim of maximal skin conservation. This was followed by thrice-daily irrigation with antibiotic-containing solution for a minimum of 2 consecutive days. The wounds healed within two to four weeks, without major cosmetic compromise.
CONCLUSION: The new method showed superior cosmetic outcomes, with a shorter duration of wound healing. Conservative surgical management can be performed under regional anaesthesia, which may reduce morbidity and mortality; patients with facial carbuncles often have higher risks with general anaesthesia.

Nail bed and flap reconstructions for acute fingertip injuries - A case review and report of a chemical burn injury

Gunasagaran J, Sian KS, Ahmad TS

J Orthop Surg (Hong Kong), 2019 4 5;27(2):2309499019839278.
PMID: 30943852 DOI: 10.1177/2309499019839278

Nail bed injuries were commonly found concomitantly with fingertip injuries. Reconstruction of fingertip including the nail bed should be attempted at acute stage. Aim of the surgery was to restore as much finger length and achieve normal nail growth. In chemical burns, the initial presentation might not reflect the exact extent of injury. Appropriate acute management must be initiated while waiting for demarcation. We report a case of young stewardess who presented with fingertip chemical burn injury. Surgical debridement was done on third day post-injury. A cross-finger flap to cover skin defect and split-thickness nail bed grafting from the remnant of injured finger were done. Excellent functional and cosmetic outcome was achieved in 6 months. Surgical treatment in a chemical burn was similar to traumatic injury. Nail bed graft was the best option for nail bed reconstruction. In cases of soft tissue loss, advancement or pedicle flaps are beneficial.

Fulltext Outcome of Islanded Gastrocnemius Musculocutaneous Flap in Orthopaedic Practice

Yusof MN, Ahmad-Alwi AA

Malays Orthop J, 2019 Mar;13(1):25-29.
PMID: 31001380 DOI: 10.5704/MOJ.1903.004

Introduction: Large wounds in the leg require combination of local flaps or free flap for wound coverage. Gastrocnemius musculocutaneous flap (GMCF) allows a large wound to be covered by a single local flap. However, the conventional GMCF is often associated with donor site morbidity where the exposed soleus raphe causes poor uptake of the skin graft. Islanding the skin on the muscles allows the donor site to be closed primarily, thus avoiding the donor site morbidity. Materials and Methods: Medical records of twelve patients who underwent islanded GMCF surgery from 2004 till 2018 were reviewed retrospectively. Results: The mean age was 31 years old. Eight cases were with open fracture of the tibia, two degloving injury exposing the patella, one open fracture of patella and necrotising soft tissue infection. The wound size ranged from 12cm2 to 120cm2. All flaps survived. Three patients required skin grafting at the donor site while in the rest the donor sites were able to be closed primarily. Four patients developed deep infection, one healed after vacuum dressing, one after bone transport and one after split thickness skin graft. One patient ended up with below knee amputation after developing chronic osteomyelitis of the tibia. Conclusion: Islanded gastrocnemius musculocutaneous flap is an effective simple alternative for coverage of large soft tissue defects from the knee to half of the leg distally with minimal donor site morbidity. Aggressive debridement of unhealthy tissue is necessary to prevent infection following wound coverage with this flap.

Complete debridement and disinfection of the root canal system are fundamental requirements for successful endodontic treatment. Despite the morphological challenges of the internal root anatomy, root canal irrigants play an important role in the optimization of the root canal preparation, which is essentially a chemo-mechanical procedure. Enterococcus faecalis is one of the most resistant microorganisms that dominants the microbial ecosystem of persistent periradicular lesions in retreatment cases. For that reason, many in vitro and in vivo studies evaluated and compared the antibacterial activity of sodium hypochlorite and chlorhexidine at varying concentrations using different experimental models against this microorganism. However, many controversies with regard to the ideal irrigant and concentration do in fact exist. Hence, this review aims to discuss the antibacterial activity of these two main root canal irrigants against Enterococcus faecalis using the agar diffusion and direct contact methods and the possible modulating factors responsible for inconsistent findings among different studies. In addition, the disinfection potential of both chemical agents on gutta percha and Resilon cones are also discussed. The source of this review was conducted through an electronic literature search using PubMed database from December 1997 until December 2011, which analyze the related laboratory investigations of both irrigants, published in major endodontic journals.

The human foot serves as an important part to support
the body weight and accounts for the majority of our
movements. A mangled limb involves injury to at least
three out of four systems, namely the soft tissues, nerves,
blood supply and bone. While amputation is indicated in
some cases of mangled limb, with proper planning, limb
salvaging surgical management is also a viable option.
Special consideration to the skeletal stabilization, control
of infection, vascular status and soft tissue coverage is
paramount to the success of limb salvaging surgery. We
present a case of mangled limb which was successfully
treated with limb salvaging surgical management. Initial
debridement, Kirschner wires insertion and cross ankle
external fixation were used for skeletal stabilization. An
antibiotic spacer was inserted for local antibiotic and to
maintain the length left due to the loss of medial and
intermediate cuneiform bones. The anterior tibialis
artery and its venae comitantes were utilized for free
vascularized fibular graft to provide bony reconstruction
as well as soft tissue coverage for the mangled foot.

Soh JA, Sheriff SO, Ramar NA, Pulikkotil SJ, Nagendrababu V, Neelakantan P, et al.

Aust Endod J, 2019 Aug;45(2):171-176.
PMID: 30230109 DOI: 10.1111/aej.12303

In endodontic infections, inflammatory mediators such as cytokines are released, recruited and retained until the infection is eradicated. Root canal therapy is performed to prevent the spread of infection. The aim of this study was to investigate the effects of root canal debridement (cleaning and shaping) on periapical inflammation by measuring the levels of inflammatory cytokines, Interleukin-8 (IL-8) and Interleukin-10 (IL-10). The study includes twenty patients with pulp necrosis and asymptomatic apical periodontitis. Periradicular sample was collected using paper points before and after root canal debridement. Cytokine levels were determined by Sandwich Enzyme-Linked Immunosorbent Assay (ELISA). Data were analysed using paired t-test (PASW Statistics 18) (P = 0.05). All samples showed the presence of IL-8 and IL-10 prior to root canal debridement. Significantly reduced levels (P < 0.05) of IL-8 and IL-10 were detected after root canal debridement. In conclusion, root canal debridement significantly decreased the levels of the tested pro- and anti-inflammatory cytokine in the periradicular interstitial fluid.

Necrotizing fasciitis (NF) is a deadly soft tissue infection causing a significant morbidity and mortality. Abdominal and chest wall NF are unusual. We describe a 49-year-old male with anterior abdominal wall NF secondary to per- forated gastric ulcer (PGU). He was admitted in septic shock presenting an abdominal wall NF with severe metabolic acidosis requiring dialysis and admission to the intensive care unit. There was a patch of gangrene with surrounding skin discoloration at lower quadrant of the abdominal wall. Local debridement was done without a preoperative computed tomography that was performed after surgery. Adequate source control was not achieved after the second surgery and the patient had worsened resulting to death. We describe this rare presentation of NF and discuss the issues learnt from this unfortunate event.

Non-surgical management of an extraoral cutaneous sinus tract of odontogenic origin

Varghese LL, Bhattacharya A, Sharma P, Apratim A

BMJ Case Rep, 2020 Jul 20;13(7).
PMID: 32690568 DOI: 10.1136/bcr-2020-234699

Chronic apical periodontitis associated with dental pulp necrosis is the main cause of odontogenic extraoral cutaneous sinus openings. These tracts are often initially misdiagnosed unless the treating clinician considers a dental aetiology. This case report of a 19-year-old woman describes the diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin. Non-surgical conservative endodontic therapy was opted as the involved teeth were restorable. One month after the completion of obturation, there was closure of the sinus tract. One year follow-up showed complete resolution of the sinus tract with minimal scar formation.

Fulltext Role of Primary Autologous Bone Graft at Docking Site in the Treatment of Infected Non-union Tibia Using Rail Fixation System

Mudiganty S, Austine J

Malays Orthop J, 2021 Mar;15(1):27-31.
PMID: 33880145 DOI: 10.5704/MOJ.2103.005

Introduction: Distraction osteogenesis has been used effectively in the management of tibia non-unions with skeletal defect. A retrospective case series study of the infected non-union tibia managed with acute docking in a rail fixation system was conducted at a tertiary care hospital in South India. It was designed to evaluate the use of autologous bone graft at the docking site in achieving an early union with a seven years follow-up period.
Materials and Methods: From 2010 to 2017, a total of 19 patients with infected tibia non-union and a bone defect less than 3cm, were treated with debridement and a monolateral frame fixation with acute shortening and lengthening. The patients were divided into two groups: one in which no bone graft was used at the docking site during early years of the study; and a later group in which autologous bone graft was used at the acute docking site primarily in addition to compression. Consolidation at the docking site was assessed both radiographically and clinically, and the results were statistically analysed.
Results: There were 12 patients in Group I without bone graft, where consolidation at the docking site was noted after a mean duration of 22.08 ± 3.87 weeks. There were seven patients in Group II with bone graft, where the mean time for docking site consolidation was significantly lower at 16.57 ± 3.82 weeks. No docking site complications were noted in either group.
Conclusion: Primary autologous bone graft enhances docking site consolidation in acute shortening. The routine use of bone graft at the docking site in acute shortening will expedite the docking site union with reduction of treatment time.

MyJurnal

Arthroscopic sub acromial debridement surgery with acromioplasty is one of the shoulder surgeries performed to treat chronic shoulder pain. This surgical procedure is usually indicated in sub acromial impingement syndrome of shoulder, degenerative rotator cuff tears, severe functional limitation of shoulder joint and often surgery was performed in cases where all the conservative management had failed in the treatment of chronic shoulder pain. Even though the patient would be referred for early rehabilitation, post operative management of this surgical condition is highly challenging. Movement of the shoulder joint is often related with scapulo-thoracic joint, acromio-clavicular joint and sternoclavicular joint and the shoulder movements are governed by various different muscular forces from these joints. Failure to understand this biomechanical complexity of shoulder joint during post operative rehabilitation results in failure of the surgical outcome and might cause severe functional limitation with recurrent shoulder pain. Often in clinical practice, greater emphasis is given to achieve and regain movements in shoulder joint at the expense of the joint stability. However, inadequate scapular stability might further predispose the shoulder joint to excessive loading and results in repetitive injuries leading to chronic shoulder pain. This might affect the surgical and clinical outcome of the acromioplasty and result in surgical failure. Hence, surgeons and clinicians need to understand the biomechanical contributions in the post operative rehabilitation of the shoulder joint. The present case report emphasises the biomechanical model of post operative rehabilitation of a patient who had arthroscopic sub acromial debridement with acromioplasty.

Fulltext Actinomycosis of Distal Phalanx Twenty Years after Flap Reconstruction of Index Finger: A Case Report

Prashant N, Azuhairy A

Malays Orthop J, 2018 Mar;12(1):48-50.
PMID: 29725514 MyJurnal DOI: 10.5704/MOJ.1803.011

Actinomycosis is a chronic granulomatous suppurative infection caused by anaerobic bacteria from genus Actinomyces which are normal flora of mouth, colon and vagina. Actinomycosis of upper extremity is rare. We report a case of actinomycosis of the distal phalanx of finger many years after flap reconstruction. The patient presented with two months' history of chronic discharging sinus from the tip of his right index finger, which had sustained a degloving injury 20 years previously. It had been treated with an anterior chest wall flap which had healed uneventfully but was bulky due to excess tissue from the donor site. Radiograph revealed osetomyelitis changes of distal phalanx. Debulking surgery with curettage of the distal phalanx was done. Wound healing was uneventful. He was treated with six weeks of metronidazole and ciprofloxacin. The discharge from the distal phalanx cultured actinomycosis odontolyticus. Histopathology of the debrided tissue showed chronic inflammation. As far as we are aware, there are no reports of actinomycosis in a flap involving the finger treated previously with a chest wall skin flap. The infection was probably dormant for many years before manifesting as a discharging sinus. Although the finger flap was bulky, it was not problematic until it started to have serous discharge. With a thorough debridement of all infected tissue, six weeks of antibiotic was adequate. Ciprofloxacin was prescribed based on discharge culture sensitivity. Metronidazole was added as actinomycosis is anaerobic. Response was prompt as patient was not immunocompromised. At follow-up six months post-surgery the finger had recovered with good function. If not for the discharging sinus, patient would probably have tolerated his bulky finger for the rest of his life.

PMID: 32918435

Morel-Lavallee lesions (MLL) are post-traumatic, closed internal degloving injuries that can result in severe complications if not diagnosed early. It is conventionally seen in cases of the high energy injuries of the pelvis and lower limb. The accumulation of extravasated blood, secondary to fracture and soft tissue damage may cause internal degloving injury, skin necrosis, soft tissue damage and acute osteomyelitis. We report here the clinical and radiological features in a 32-year-old male referred from the emergency department of a tertiary hospital who had sustained high energy motor vehicle accident. On examination, there was a fluctuant, mobile, non-tender subcutaneous mass over the distal arm with suspicion of internal degloving injury. Plain radiographs showed no fractures. Ultrasound showed a fluid collection with the presence of septations and echogenic debris within the collection. Extravasation was noted between subcutaneous tissue layer and fascia at the posterolateral aspect of the arm. Wound debridement under general anaesthesia was carried out. Intraoperative findings reported a significant amount of thick serous fluid with necrotic debris. Unhealthy skin and fat layers were debrided. Underlying muscles were found to be healthy. The results of the intraoperative fluid culture and sensitivity showed no growth. Negative pressure vacuum dressing was carried out. After five cycles of vacuum dressing, the wound showed signs of healing with an improved range of motion of the elbow. Orthopaedic surgeons need to be vigilant of the possibility of MLL in the upper limb as a differential diagnosis in the management of high energy trauma.

Unexpected sequelae of plantar fasciitis: Iatrogenic calcaneal osteomyelitis following plantar heel injection

Mohd Khalid SA, Bajuri MY

Malays Fam Physician, 2019;14(3):80-83.
PMID: 32175048

The injection of a local anesthetic in combination with a corticosteroid is an accepted choice in the treatment of plantar fasciitis with recalcitrant heel pain. When the injection is performed properly, post-injection infection is extremely rare. We are reporting a rare case of chronic calcaneal osteomyelitis that developed secondary to a local corticosteroid injection. A 56-year-old lady diagnosed with right plantar fasciitis presented with a 6-month history of pain and a persistent sinus with serous discharge of her right heel following a local infiltration of a corticosteroid. A Magnetic Resonance Imaging demonstrated right calcaneal osteomyelitis with intramuscular abscess. Surgical drainage and debridement were done, followed by antibiotic therapy. A recurrence of infection was not detected throughout the duration of follow-up. It is suggested that a plantar heel injection be done in a more controlled environment, such as in operating theatre, to reduce the risk of infection and to avoid injecting a steroid as compared to platelet-rich plasma (PRP) in view of their safety profiles. However, such an injection should only be offered after conservative treatment has failed, as 80% of patients recover well after initial conservative management.

Use of commercially available sodium hyaluronate 0.18% eye drops for corneal epithelial healing in diabetic patients

Ling K, Bastion MC

Int Ophthalmol, 2019 Oct;39(10):2195-2203.
PMID: 30536185 DOI: 10.1007/s10792-018-1057-1

PURPOSE: To evaluate the effect of topical sodium hyaluronate (SH) 0.18% treatment on corneal epithelial healing after epithelial debridement in pars plana vitrectomy in diabetic patients.
METHOD: This is prospective and randomized clinical trial. Our study population included 30 eyes undergoing pars plana vitrectomy that required near total corneal debridement intra-operatively for surgical view. We compared the residual wound and wound healing rate in between 3 groups: 10 diabetic eyes (DMV) on topical SH 0.18%; 10 diabetic eyes (DMC) and 10 non-diabetic eyes (NDM) not treated with topical SH 0.18%. The corneal epithelial wound was measured at 12, 24, 36, 48, 60, 72 and 120 h after the vitrectomy surgery.
RESULTS: DMC group had corneal wounds that reepithelialization significantly more slowly than in NDM and DMV groups at 12, 24, 36 and 48 h (Mann-Whitney test p

Fai S, Ahem A, Mustapha M, Mohd Noh UK, Bastion MC

Asia Pac J Ophthalmol (Phila), 2017;6(5):418-424.
PMID: 28828764 DOI: 10.22608/APO.201780

PURPOSE: To determine the effect of topical insulin of 3 concentrations [0.5, 1, and 2 units per drop 4 times per day (QID)] on postoperative corneal epithelial wound healing in diabetic patients.
DESIGN: A double blind randomized controlled hospital-based study involving diabetic patients with postoperative corneal epithelial defect after vitreoretinal surgery.
METHODS: Diabetic patients were randomized to 3 different concentrations of topical insulin (DTI 0.5, DTI 1, and DTI 2) or placebo in the control group (DNS). Primary outcome measure was the rate of corneal epithelial wound healing (mm² per hour) over pre-set interval and time from baseline to minimum size of epithelial defect on fluorescein stained anterior segment digital camera photography. Secondary outcome measure was any adverse effect of topical insulin. Follow-up was 1 month.
RESULTS: Thirty-two eyes of 32 patients undergoing intraoperative corneal debridement with resultant epithelial defect (8 eyes per group) were analyzed. DTI 0.5 was superior to other concentrations achieving 100% healing rate within 72 hours of treatment compared with 62.5% in DNS, 75% in DTI 1, and 62.5% in DTI 2. Statistically, DTI 0.5 achieved significant results (P = 0.036) compared with the diabetic control group (DNS) in terms of mean rate of corneal epithelial wound healing from maximum to minimum defect size. No adverse effect of topical insulin was reported.
CONCLUSIONS: Topical insulin 0.5 units QID is most effective for healing corneal epithelial defect in diabetic patients after vitrectomy surgery compared with placebo and higher concentrations. Topical insulin is safe for human ocular usage.
