Using Maggot Debridement Therapy in Treatment of Necrosis in the Forearm Caused By Docetaxel Extravasation: A Case Report

Extravasation of doxorubicin, vincristine or vinblastine leads to necrosis, damage of the muscles and nerves, deep ulceration, as well as limb dysfunction. Necrosis and deep ulcers develop within 7 to 28 days. Like necrotomy, Lucilia sericata maggot therapy is recognised as a method enabling effective, safe and quick removal of necrotic tissue. The purpose of the study was to present local treatment of hypodermic necrosis caused by docetaxel extravasation in course of systemic cancer therapy. A woman, 59 years of age, in course of systemic therapy due to advanced cancer of the left breast (T2N1M1 CS IV) with confirmed metastases within the body of the fourth lumbar vertebra and in the liver, receiving a combination treatment with pertuzumab, trastuzumab, and docetaxel. During the therapy, a conservative treatment was applied due to extravasation for over three months. Effects in the right forearm included swelling, redness, signs of 4x10cm inflammatory infiltrate, with 1x4cm necrotic crust visible in the central region. Hypodermic necrosis was debrided using L. sericata maggots, and subsequently specialist dressings were applied to promote granulation and healing. In the case discussed here, effectiveness of MDT was rather poor, however the treatment minimised the risk of infection associated with evacuation of necrosis. Attempts to use MDT should be continued to enable more comprehensive understanding of problems related to management of necrosis in wounds developing during cancer therapy.

Choledochoduodenal fistula: a rare complication of acute peptic ulcer bleeding

A 75-year-old man presented with a 3-week history of melaena and right upper quadrant pain. This was on a background of significant alcohol intake and a complex medical history. He was haemodynamically unstable with investigations indicating a new iron-deficiency anaemia. After resuscitation, urgent intervention was required under general anaesthesia. This involved a triple phase abdominal CT, followed by emergency oesophagogastroduodenoscopy. This revealed deep ulceration with extension to the pancreatic head and common bile duct. There was also evidence of pneumobilia on CT, secondary to a choledochoduodenal fistula. Treatment encompassed an invasive and medical approach. Following treatment, the patient was stable, with follow-up endoscopy exhibiting good duodenal mucosal healing.

IL-1-driven stromal–neutrophil interactions define a subset of patients with inflammatory bowel disease that does not respond to therapies

Current inflammatory bowel disease (IBD) therapies are ineffective in a high proportion of patients. Combining bulk and single-cell transcriptomics, quantitative histopathology and in situ localization across three cohorts of patients with IBD (total n = 376), we identify coexpressed gene modules within the heterogeneous tissular inflammatory response in IBD that map to distinct histopathological and cellular features (pathotypes). One of these pathotypes is defined by high neutrophil infiltration, activation of fibroblasts and vascular remodeling at sites of deep ulceration. Activated fibroblasts in the ulcer bed display neutrophil-chemoattractant properties that are IL-1R, but not TNF, dependent. Pathotype-associated neutrophil and fibroblast signatures are increased in nonresponders to several therapies across four independent cohorts (total n = 343). The identification of distinct, localized, tissular pathotypes will aid precision targeting of current therapeutics and provides a biological rationale for IL-1 signaling blockade in ulcerating disease.

IL-1-driven stromal-neutrophil interaction in deep ulcers defines a pathotype of therapy non-responsive inflammatory bowel disease

Current inflammatory bowel disease (IBD) therapies are ineffective in a high proportion of patients. Combining bulk and single-cell transcriptomics, quantitative histopathology, and in situ localisation, we describe heterogeneity of the tissular inflammatory response in IBD treatment failure. Among inflammatory pathotypes, we found high neutrophil infiltration, activation of fibroblasts, and vascular remodelling at sites of deep ulceration was a feature of non-response to several anti-inflammatory therapies. Activated fibroblasts in the ulcer bed display neutrophil chemoattractant properties that are IL-1R- but not TNF-dependent. The identification of distinct, localised, tissular pathotypes associated with treatment non-response will aid precision targeting of current therapeutics and provide a biological rationale for IL-1 signalling blockade in ulcerating disease.

Opportunistic penicilliosis infection causing intestinal obstruction in people living with HIV complicating antiretroviral therapy

We report a retroviral positive patient who presented to us with recurrent skin lesions along with intermittent, colicky periumbilical abdominal pain associated with non-projectile, postprandial vomiting. Contrast-enhanced CT (CECT) of abdomen and pelvis was suggestive of proximal jejunal obstruction. Double balloon enteroscopy done which showed extensive deep ulceration with surrounding nodular surface and friable mucosa at 60 cm from pylorus with luminal narrowing. The biopsy from this region as well as the skin lesion on the forehead grew Talaromyces marneffei. She was initially treated with liposomal amphotericin B for 2 weeks following which she received itraconazole for 3 weeks for disseminated talaromycosis infection. She had already been started on antiretroviral therapy (ART) 1 year back however her cluster of differentiation 4 (CD4) counts did not show any improvement. Proximal bowel obstruction leading to poor nutritional status compounded with ineffective ART therapy due to suboptimal absorption, dictated the staged management of her condition. Feeding jejunostomy was done with a plan to offer her resection and anastomosis of affected jejunal segment, should she require one, after optimising her nutritional and immunological status.

Managementof squamos cell carcinoma of tongue in young men: case report

Background: Oral Squamous cell carcinoma is the most common malignant neoplasm of the oral cavity, usually affecting individuals over 50 years of age. It rarely occurs in patients who are less than 40 years old. Purpose: This case report aim is to focuses on establishment of diagnosis, differential diagnosis, predisposition, and treatment planning related to the case. Case: This report describes a case of oral squamous cell carcinoma, staged T1N1M0 (stage III), involving the lateral border and ventral surface of the tongue of a 32-year old male patient, with no smoking or drinking habits. Initial tumor presentation was of deep ulceration and intense pain. Case Management: Patient has examination with autofluorence LED light, presence of bacterial growth, and FNA for establised diagnosis. Patient was given chlorine dioxide mouthwash and education for further treatment one of them is tomoterapi. Conclusions: Clinical features of deep ulceration, pain and induration may be a suspicious feature of oral cavity cancer, therefore early diagnosis of oral squamous cell carcinoma determines prognosis.Keywords: malignant, autofluoresence, tomoterap

Neoterminal Ileal Polyposis and Ulceration after Restorative Proctocolectomy with a Current Review of the Literature

After ileal pouch anal anastomosis, one of the frequently encountered complications is polyposis of the pouch. We describe a case of proximal neoterminal ileal polyposis associated with deep ulceration suggestive of Crohn’s disease and review the available literature. A 36-year-old male presented with resistant pouchitis 11 years after surgery for ulcerative colitis. With all-negative initial workup, pouchoscopy showed multiple deep ulcers in the proximal ileum with some polyps. Biopsy of polyps showed inflammatory polyps with negative immunohistological staining for IgG pouchitis. With no treatable etiology for pouchitis and the presence of inflammatory polyps, there are no guidelines for surveillance of this condition. Definitive diagnosis is challenging and there is no consensus or recommended guidelines on the management.

Parapoxviral vulvovaginitis in Holstein cows

A group of Holstein first-calved heifers developed small pustules and ulcers on the vulva and in the vagina during the first 1–4 wk postpartum. The lesions varied from small red pinpoint foci to pustules and ulcers, 3–5 mm diameter. Some ulcers coalesced to form large ulcerated areas up to 15 mm diameter. In some animals, these ulcers progressed to become deep ulceration of the vaginal and vulvar mucosa with >50% of the mucosa involved. Vaginal biopsies from 4 heifers and vaginal individual swabs from 8 heifers for a combined sampling of 9 heifers were taken for clinical assessment. Six of the 9 heifers had parapoxvirus based on histopathology and/or PCR. Histologic examination of the biopsies of the pustules identified ballooning degeneration of the epithelium with degenerate epithelium containing eosinophilic intracytoplasmic inclusions consistent with a parapoxvirus in 3 of 4 biopsies. Testing for bovine herpesvirus 1, 2, and 4, bovine viral diarrhea virus, bovine papular stomatitis virus, and orf virus remained negative.

Surgical management of a hand extravasation of anthracycline at late presentation

<p>Anthracycline extravasation remains a feared serious complication of chemotherapy. At late presentation, deep ulceration and extensive soft tissue damage are seen. Hand extravasation of anthracycline may lead to tendon and nerves destruction with functional and economical impairments. We report a case of Epirubicin extravasation seen at day 25 in a 46-year-old woman treated for breast cancer. A groin flap failed due to the persistence of anthracyclin in the wound. A split thickness skin graft was done after all the tendons were removed. The chemotherapy was interrupted for two months. Wide serial debridements are needed to achieve the removal of all molecules of anthracycline that are observed when granulating tissue is observed permanently in the wound.</p><p> </p>

Pyoderma Gangrenosum: A Rare Cause of Cutaneous Ulceration and One Easily Misdiagnosed

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis often misdiagnosed. It is uncommon in infants and children accounting for 4% of cases. A one-year-old male in paediatric ICU ventilated for bronchopneumonia was referred with ulcerated areas on his neck and axilla corresponding to sites of recent removal of central and arterial lines. Examination revealed areas of deep ulceration with violaceous undermined borders in keeping with PG. This was supported by a skin biopsy showing a neutrophilic infiltrate in the deeper dermis. Topical clobetasol propionate was commenced and a dramatic improvement within 24 hours noted. Blood results showed a leucocytosis of 29.7; a differential WCC showed toxic granulation in neutrophils with myeloid left shift; immunoglobulins showed elevated IgG 23 and IgA 4.86. The elevated WCC made us consider a leukaemic trigger; however, they settled with treatment of the underlying infection. PG in children is more likely to have an atypical distribution involving the head and neck (26.6%) or buttocks (15%). An interesting feature in this case is the presence of pathergy, a term used to describe the induction or exacerbation of PG at sites of iatrogenic or incidental trauma. It is seen in 31% of patients with PG.
