Aspergillus niger as a rare cause of postarthroscopy knee septic arthritis in a healthy patient.

This case report outlines the diagnostic and therapeutic challenges encountered in a man in his 70s suffering from knee septic arthritis caused by Aspergillus niger It is the second published case in the literature with osteoarticular infection from A. niger and the first one in the last 40 years. Following knee arthroscopy, the patient experienced persistent pain, swelling and discomfort, prompting further investigation. Postoperative knee cultures were negative for infection, but symptoms were not ameliorated. Therefore, an arthroscopic debridement was performed that revealed severe joint inflammation and degeneration. Cultures from the synovial fluid and tissue samples identified infection from A. niger sp. Antimicrobial treatment with voriconazole finally led to significant clinical improvement and eradication of infection. This case highlights the intricacies involved in diagnosing and managing fungal osteoarticular infections in healthy patients without concomitant medical diseases or comorbidities.

LAMN port-site metastasis after laparoscopic oophorectomy for a presumed ovarian tumour treated with CRS and HIPEC.

Low-grade appendiceal mucinous neoplasm (LAMN) may culminate as a mucin-secreting disease known as pseudomyxoma peritonei (PMP). Once the diagnosis of LAMN and PMP is made, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS and HIPEC) are indicated.Herein, we present a female patient in her 50s who was diagnosed with an ovarian mass for which she underwent laparoscopic oophorectomy. As the pathology of the ovary showed a tumour of gastrointestinal origin, she then underwent CRS and HIPEC with a final pathology of LAMN. Six weeks later, a mucinous lesion confined to the abdominal wall was detected on a postoperative CT. Suspected for port-site metastasis at the laparoscopic trocar site, we treated this lesion using the same principles of treatment as the intra-abdominal disease. The abdominal wall mass was surgically resected, and the cavity created was irrigated with mitomycin C. On 30 months of follow-up, the patient had no evidence of disease.

Tumescent solution: a game changer in excising refractory arteriovenous malformation.

Arteriovenous malformations of the head and neck are rare and inborn errors of vascular morphogenesis. They pose therapeutic challenges owing to their bleeding tendency and a high chance of recurrence. Treatment modalities include digital subtraction angiography with embolisation as a primary treatment or can be done preoperatively followed by surgical excision. We present a case of recurrent arteriovenous malformation of the postauricular region in an adolescent male who was taken up for upfront surgical excision with the help of a tumescent solution, thereby eliminating the need for embolisation and drastically reduced intraoperative blood loss.

Capecitabine-induced severe adverse events-therapeutic drug monitoring and DPYD-gene analysis are recommended.

In this report, two cases of patients with severe adverse events after an adjuvant treatment with capecitabine are described in detail. The first patient suffered from a severe ileocolitis, where ultimately intensive care treatment, total colectomy and ileum resection was necessary. The second patient experienced a toxic enteritis, which could be managed conservatively. Post-therapeutic DPYD genotyping was negative in the former and positive in the latter case. Patients can be categorised in normal, moderate and poor DPYD metabolisers to predict the risk of adverse events of capecitabine treatment. Guidelines in various European countries recommend pretherapeutic DPYD genotyping, whereas it is not recommended by the National Comprehensive Cancer Network in the USA. Irrespective of DPYD genotyping, strict therapeutic drug monitoring is highly recommended to reduce the incidence and severity of adverse events.

Aversion of surgical exploration in patients with complex ovarian cysts secondary to overt hypothyroidism: A series of three cases.

Long-standing, overt hypothyroidism-induced bilateral multiloculated ovarian cysts represent an infrequent occurrence. Our first case, presented with bilateral complex ovarian masses, exhibited overt hypothyroidism symptoms, including lethargy, weight gain and subfertility, prompting consideration for surgical intervention. Similarly, in the second case, a girl aged 11 years with stunting, delayed bone age and academic challenges was referred for surgical exploration due to bilateral complex ovarian masses. Both cases revealed elevated thyroid-stimulating hormone levels during preoperative workup. Commencing levothyroxine replacement therapy resulted in complete regression of ovarian cysts and substantial symptom improvement within an 8-week timeframe. The third case, a previously diagnosed patient with Hashimoto's thyroiditis, benefited from the lessons gleaned in managing the initial cases, responding well to levothyroxine therapy, thereby averting the necessity for surgery in all three instances. These cases underscore the significance of considering thyroid function in the evaluation of ovarian masses and highlight the efficacy of levothyroxine replacement therapy in resolving both hypothyroidism and associated ovarian cysts, thereby obviating the need for surgical intervention.

Long-term recurrence-free survival following pancreatic surgery with HIPEC treatment for locally advanced pancreatic adenocarcinoma.

More than 5 years previous to this report, a female patient in her 60s underwent oncological left-sided pancreatic resection and adrenalectomy including splenectomy for locally advanced pancreatic adenocarcinoma (PDAC), recommended by a multidisciplinary tumour board (MDT). Additionally, she was treated with gemcitabine-containing hyperthermic intraperitoneal chemotherapy (HIPEC) for 60 minutes in the framework of a clinical trial (PanHIPEC), aiming to determine the safety and feasibility (not efficacy) of this approach. Following the postoperative MDT recommendation, she subsequently received adjuvant chemotherapy consisting of six cycles of gemcitabine and cisplatin for a histopathologically confirmed PDAC of the pancreatic tail with infiltration of the left-sided adrenal gland (pT3, pN1 (3/16), cM0, L0, V0, Pn1, R0, G2). Five years and five months after pancreatic surgery and HIPEC, the patient has no signs of tumour recurrence as determined by follow-up examination including CT scan and CA19-9 tumour marker serology.

Successful management of massive postpartum haemorrhage in a woman with acquired haemophilia A.

Postpartum haemorrhage (PPH) is an obstetric emergency and a leading cause of severe maternal morbidity and mortality. Timely and accurate diagnosis of the underlying cause of PPH is critical in achieving optimal care for the patient as any potential delays may result in severe morbidity and even mortality. We present a rare case of a patient presenting with PPH secondary to acquired haemophilia. This case highlights the importance of early diagnosis and multidisciplinary management in achieving optimal management of this complex condition.

Denosumab for an inoperable giant cell tumour of the ischial bone.

Giant cell tumour of bone is a benign, locally aggressive osteolytic tumour that typically affects skeletally mature young individuals. It predominantly emerges within the metaphysis, extending towards the epiphysis of long bones, while occurrences in flat bones are exceptionally rare. We present a case of a woman in her late 20s who presented with a large right ischial mass. A biopsy confirmed the mass as a giant cell tumour. The tumour extended to the acetabulum, and due to the potential risk of significant bleeding and contamination during en bloc excision, a prudent approach involved initiating denosumab therapy, a monoclonal antibody targeting receptor activator of nuclear factor-κB ligand therapy, before proceeding with radical surgery. Denosumab therapy successfully rendered a previously inoperable tumour favourable for surgical intervention. We went on to perform a type 2 and 3 internal hemipelvectomy, followed by a reconstruction with a hip endoprosthesis replacement.

Management of a complex acetabular fracture following defibrillation for ventricular fibrillation cardiac arrest.

In this case report, we describe the first case of a patient who sustained a complex acetabular fracture following defibrillation for ventricular fibrillation cardiac arrest in the context of acute myocardial infarction. The patient was unable to undergo definitive open reduction internal fixation surgery due to the need to continue dual antiplatelet therapy following coronary stenting of his occluded left anterior descending artery. Following multidisciplinary discussions, a staged approach was opted for, with percutaneous closed reduction screw fixation of the fracture performed while the patient was maintained on dual antiplatelet therapy. The patient was discharged with a plan to perform definitive surgical management when safe to discontinue dual antiplatelets. This is the first confirmed case of defibrillation causing an acetabular fracture. We discuss the various aspects that need to be considered when patients are being worked up for surgery while on dual antiplatelet therapy.

Enterocutaneous fistula formation after cardiac transplantation due to injury from LVAD driveline migration.

A man in his early 20s with heart failure with reduced ejection fraction secondary to non-compaction cardiomyopathy (Titin (TTN) gene mutation positive) was transitioned from left ventricular assist device (LVAD) mechanical support to heart transplantation. Transplantation was successful; however, LVAD explantation resulted in innumerable complications secondary to penetration of the driveline into the peritoneal cavity. He developed an enterocutaneous fistula which led to concurrent malnutrition, poor wound healing, systemic infection, and allograft rejection in a patient less than 1 month after heart transplantation on immunosuppression.

Surgical management of spontaneous bowel perforation and fascial dehiscence in a patient on bevacizumab and pembrolizumab in the setting of active Clostridium difficile infection.

Immunotherapy such as bevacizumab and pembrolizumab is used to treat an increasing number of malignancies. These medications have been associated with poor wound healing and several gastrointestinal complications, including intestinal perforations in rare cases. We present a unique case of a patient with metastatic cervical cancer on pembrolizumab and recent bevacizumab therapy, presenting with a colonic perforation requiring urgent exploratory laparotomy, in the setting of active Clostridium difficile infection. She required a second laparotomy shortly after due to fascial dehiscence, where a synthetic absorbable mesh was used for fascial approximation. We review the factors that led to these events and describe the surgical technique used for safe abdominal closure.

Acute ischaemia of the glans penis post-circumcision managed with pentoxifylline, topical nitroglycerin and epidural.

Acute ischaemia of the glans penis is a rare and serious complication following circumcision. We report the case of a teenage boy with glanular ischaemia shortly after circumcision with dorsal penile nerve block. This was successfully treated with total 11 days of topical 2% nitroglycerin ointment, 14 days of oral pentoxifylline 400 mg three times a day and 3 days of epidural (0.2% ropivocaine). There was marked clinical improvement at 4 days with a few patches of cyanosis remaining. Surgical intervention was not required, and the patient was discharged with follow-up review. At 12 days, there was complete resolution of ischaemia and the glans penis appeared normal. We suggest that oral, topical and epidural regimen of vasodilators and anti-sympathomimetic agents can be used in combination for acute ischaemia of the glans penis.

Myocardial infarction after craniotomy for asymptomatic meningioma.

A man in his 40s with a history of coronary artery disease previously treated with a drug-eluting stent presented for elective craniotomy and resection of an asymptomatic but enlarging meningioma. During his craniotomy, he received desmopressin and tranexamic acid for surgical bleeding. Postoperatively, the patient developed chest pain and was found to have an ST-elevation myocardial infarction (MI). Because of the patient's recent neurosurgery, standard post-MI care was contraindicated and he was instead managed symptomatically in the intensive care unit. Echocardiogram on postoperative day 1 demonstrated no regional wall motion abnormalities and an ejection fraction of 60%. His presentation was consistent with thrombosis of his diagonal stent. He was transferred out of the intensive care unit on postoperative day 1 and discharged home on postoperative day 3.

Bromfenac-induced neurotrophic keratitis in a corneal graft.

A man in his 30s, with a history of two operated penetrating keratoplasty (PK), primarily for viral keratitis, presented with pain, redness and diminution of vision in his left eye of 4 days duration. Postoperatively, he was prescribed oral antivirals, topical steroid eyedrops, lubricants and antiglaucoma medications. Eight months after transplantation, an epithelial defect with heaped up margins was noted on anterior segment evaluation on a routine follow-up visit. On checking his medications, it was found that the patient was unknowingly using bromfenac drops in place of brimonidine tartrate for the past month. A diagnosis of neurotrophic keratitis was made in the setting of PK performed for viral keratitis, incited by use of topical bromfenac. The patient was prescribed preservative-free lubricants with immediate discontinuation of bromfenac drops. Topical steroid drops were withheld till the epithelial defect healed. Complete healing of the defect was noted after 4 weeks of therapy.

Intraoperative acute compartment syndrome of the upper limb secondary to extravasation.

A woman in her 50s was undergoing a repeat liver resection surgery for recurrence of liver metastasis when the intravenous fluid flow was noted to be sluggish on multiple occasions. On the third examination of the right hand where the intravenous cannula was located, surgery was halted as there was extensive swelling from the hand to the biceps and the hand had started turning blue. A diagnosis of acute upper limb compartment syndrome secondary to extravasation exacerbated by metaraminol was made by the anaesthetist and surgeon. Fasciotomies of the right upper limb were performed, and perfusion was restored. A hand surgeon arrived shortly after and completed decompressing the upper limb compartments.A literature review revealed risk factors such as communication barriers, age and chemotherapy were present in this case. Enhanced monitoring is needed in the context of unsatisfactory infusion flow rates perioperatively.

Rare presentation of enoxaparin-induced skin necrosis in a postoperative patient.

Enoxaparin-induced skin necrosis is a rare complication of low-molecular weight heparin (LMWH) therapy. We describe a woman in her 50s who developed deep vein thrombosis (DVT), thrombocytopenia and necrotic skin lesions after initiation of enoxaparin for DVT prophylaxis. Despite high clinical suspicion of heparin-induced thrombocytopenia syndrome and a positive heparin-platelet factor 4 antibody, heparin serotonin assay was negative. This case emphasises the importance for clinical vigilance regarding complications to LMWH therapy.

Acute limb ischaemia due to vasospasm: a rare presentation.

A 30-year-old woman with active intravenous drug use presented with pain, blue discolouration, paresthesia and lack of grip strength of left hand for 1 week. Physical examination revealed blue discolouration, decreased sensation and cold to touch in the left hand. She had no palpable radial pulse. She admitted Heroin use only but the urine drug screen was also positive for amphetamine. CT angiogram of the left upper extremity was concerning for acute ischaemia due to arterial occlusion. The initial plan was for amputation. However, to salvage the limb with thrombolysis, an interventional radiology angiogram was performed. The angiogram demonstrated diffuse arterial spasm and response to nitroglycerin. She was treated with nitroglycerin drip and transitioned to a calcium channel blocker. She did improve significantly. To ensure no embolic sequelae, the patient was discharged with a month of oral anticoagulation.

Is surgical exploration necessary in asymptomatic intestinal pneumatosis after lung transplantation?

Pneumatosis intestinalis is described as gas within the bowel wall and can be a sign of bowel ischaemia with a pending perforation. The described patient presented with the incidental diagnosis of pneumatosis intestinalis with free intraperitoneal gas on CT scan. His medical history included a successful lung transplantation. We here describe the clinical decision-making and evaluate our case with previous cases in the literature.

Novel application of infliximab for diversion colitis.

Diversion colitis (DC) that was refractory to standard treatments was successfully treated with infliximab. A 24-year-old man with a transverse colostomy suffered from severe DC. Topical steroids, 5-aminosalicylic acid (5-ASA) enemas and synbiotics were initially effective, and the colostomy was successfully closed with a covering ileostomy to minimise the risk of anastomotic leakage owing to the damaged colon. DC subsequently relapsed in the entire colon and was refractory to the previous protocol and autologous faecal transplantation. Intravenous methylprednisolone and oral 5-ASA were discontinued owing to possible adverse effects. Infliximab with intravenous prednisolone was introduced, and the protocol was so effective in suppressing the acute colitis that total colectomy was avoided. The stoma was subsequently closed, and the patient is currently symptom-free. Infliximab is used for ulcerative colitis but could also be effective against severe DC.

Acquired cryptorchidism: an unexpected consequence of inguinoscrotal lymphatic malformation treated with Eppikajutsuto.

Lymphatic malformation (LM) that causes inguinoscrotal swelling is extremely rare. Surgery, sclerotherapy and pharmacotherapy have been reported as possible treatment options for LM. Recently, Eppikajutsuto (TJ-28), a traditional Japanese herbal medicine has emerged as therapeutic option for LM. We report the case of a 2-year-old boy who presented with a left inguinoscrotal swelling, which was diagnosed as retroperitoneal LM extending into the left scrotum. The surgical approach was less favourable, given the risk of damaging the testicular vasculature or the spermatic cord. Therefore, the patient received medical treatment with TJ-28. As a result, a volume reduction of 83% was obtained, as well as the unexpected consequence of the left testicle retracting into the inguinal area. Laparoscopic exploration was performed and a small bulge on the internal inguinal ring was detected. The patient's acquired cryptorchidism was subsequently treated by orchidopexy.
