Abstract
BACKGROUND Thrombotic thrombocytopenic purpura and hemolytic uremic syndrome are two forms of thrombotic microangiopathies. They are characterized by severe thrombocytopenia, microangiopathic hemolysis, and thrombosis, leading to a systemic inflammatory response and organ failure. Plasmapheresis is used to treat thrombotic microangiopathies. A different entity known as atypical hemolytic uremic syndrome has garnered more clinical recognition because reported cases have described that it does not respond to standard plasmapheresis. Diclofenac potassium is a non-steroidal anti-inflammatory drug that is used to treat pain. CASE REPORT A 35-year-old Hispanic man presented to our emergency department with complaints of generalized malaise, fever, and an evanescent skin rash. During admission, he reported the use of diclofenac potassium for back pain on a daily basis for 1 week. He was noted to have peripheral eosinophilia, so he was admitted for suspected drug reaction involving eosinophilia and systemic symptoms. His initial laboratory work-up showed microangiopathic hemolytic anemia and thrombocytopenia. He also experienced a seizure, encephalopathy, and had a PLASMIC score of 7, thus raising concerns for thrombotic thrombocytopenic purpura. He underwent emergent plasmapheresis, which improved his clinical condition. The diagnosis was confirmed by assessing the levels of disintegrin and metalloproteinase with thrombospondin type 1 motif, member 13, which was less than 3%. In addition, his skin biopsy was positive for patchy complement deposition, demonstrating complement dysregulation. CONCLUSION Thrombotic thrombocytopenic purpura is a rare condition that can be acquired. Our case is rare because it represents the first report of diclofenac potassium-induced thrombotic thrombocytopenic purpura with subjacent complement activation and dysregulation. Early recognition and aggressive management led to a favorable outcome.

Abstract
INTRODUCTION Elevation in body temperature within the first 24 hours of ischemic stroke is fairly common and known to be associated with worse outcomes. Only after thoroughly ruling out infection and the noninfectious etiologies and in the appropriate clinical setting should the diagnosis of central fever be made. Acetaminophen and nonsteroidal anti-inflammatory drugs are typical therapeutic options. External cooling is frequently used when pharmacologic interventions are inadequate. However, reports have suggested that neurogenic fevers are somewhat resistant to traditional pharmacologic therapies. CASE PRESENTATION We describe a case of a Caucasian patient with central fever after ischemic stroke not responsive to acetaminophen administration and external cooling. After an initial bolus of diclofenac sodium (0.2 mg/kg in 100 ml of saline solution for 30 minutes), a continuous infusion (75 mg in 50 ml of saline solution) was started. After 5 days of treatment, the patient's body temperature was below 37.5 °C, and the diclofenac sodium infusion was stopped. CONCLUSIONS We observed that a low-dose diclofenac sodium infusion was effective in treating fever without systemic side effects. This treatment may be suggested as an alternative to conventional antipyretic drugs, but additional clinical trials are required.

Savoia, F, Sechi, A, Tabanelli, M, Zago, S, Leuzzi, M, Baraldi, C, Patrizi, A
The Australasian journal of dermatology. 2019;(1):50-52
Abstract
We report a case of long-standing inexplicable perianal ulcers. After exclusion of an inflammatory, infectious or neoplastic origin, a thorough personal history revealed that for many years the patient had been using analgesic suppositories containing indomethacin, caffeine, and prochlorperazine dimaleate, four to five times a week, for migraine. On stopping the suppositories, there was complete healing within 12 weeks. We hypothesize that vasoconstriction and vascular damage were the pathogenetic mechanisms behind the perianal ulcers.

Abstract
PURPOSE Gyrate atrophy of the choroid and retina (GACR) is a rare chorioretinal dystrophy characterized by a deficiency of the enzyme ornithine aminotransferase, inherited in an autosomal recessive pattern. CASE REPORT We report a case of a 17-year-old girl with GACR, for whom the level of serum ornithine had been reduced by an arginine-restricted diet. The patient was responsive to an association of topical nonsteroidal anti-inflammatory drugs (NSAIDs) and a carbonic anhydrase inhibitor (CAI) to reduce cystoid macular edema (CME). CONCLUSIONS The efficacy of topical NSAIDs and systemic CAI association indicates that the imbalance in the distribution of retinal pigment epithelium membrane-bound carbonic anhydrase could play a major role in CME pathogenesis in GACR. To our knowledge, this is the first case of therapy with CAI treatment for GACR-related CME.

Journal of medical case reports. 2014;:397
Abstract
INTRODUCTION Cheilitis granulomatosa causes persistent idiopathic lip swelling and ulceration and it can sometimes be recognized as a unique or early manifestation of Crohn's disease. Spontaneous remission is rare and with the lack of controlled trials, different therapeutic approaches have been used. Some cases have been treated with an exclusion diet in the attempt to rule out diet allergens, while the most popular treatments include antibiotics such as tetracycline and clofazimine tranilast, benzocaine topical or intralesional steroids, and cheiloplasty, with different outcomes. CASE PRESENTATION We describe the case of a 23-year-old Caucasian man, primarily diagnosed with cheilitis granulomatosa for a severe lower lip swelling, and then with Crohn's disease of the terminal ileum and anus. Treatment of Crohn's disease with an anti-tumor necrosis factor alpha agent (infliximab) successfully induced remission of both the gastrointestinal disease and the oral lesion. CONCLUSIONS Our recommendation is that physicians should be able to recognize cheilitis granulomatosa as a possible marker of a more complex systemic disease and proceed first with an accurate physical examination, and further suggest investigations of the bowel. In cases of Crohn's disease, a therapy with biological agents can be successful.

Abstract
Most of the clinical data on the safety profile of desmopressin (DDAVP), which is an effective treatment for both polyuric conditions and bleeding disorders, originate from studies on the tailoring of drug treatment, whereas few reports exist describing severe side effects secondary to drug-drug interaction. We herein describe a case of severe hyponatremia complicated by seizure and coma due to the intake of non-steroidal anti-inflammatory drugs (NSAIDs) in a patient on DDAVP replacement therapy for central diabetes insipidus (DI). A 50-yr-old Caucasian man, with congenital central DI, developed an episode of generalized tonic-clonic seizure, resulting in coma immediately after being admitted to the Emergency Unit for weakness and emesis. Based on his medical history and clinical findings, water intoxication secondary to ketoprofen intake (200 mg/day for the last 3 days) concomitant with DDAVP replacement therapy (Minirin(®) 60 mcg 4 tablets a day) was hypothesized as being the cause of the severe euvolemic hypotonic hyponatremia (natremia 113 mEq/l, plasma osmolality 238 mOsm/Kg). After standard emergency procedures, appropriate gradual restoration of serum sodium levels to the normal range was achieved in 72 hours. Hydratation was maintained according to water excretion and desmopressin therapy was re-introduced. We discuss this case report in the context of the published literature. The present report first highlights the potentially life-threatening side effects associated with over-the-counter NSAIDs during DDAVP replacement therapy for central DI. Risks and benefits of co-treatment should be carefully considered and therapeutic alternatives to NSAIDs should be recommended to patients with central DI in order to improve DDAVP safety.

Abstract
A 50-year-old woman was admitted to our hospital with complaints of loss of vision, diarrhea and arthralgia. She was given a diagnosis of Behçet disease and given infliximab (IFX) to halt the progression of acute vision loss. Liver damage was detected after the fourth IFX dose. We assumed that this was a drug-induced condition caused by salazosulfapyridine (SASP). However, the liver damage worsened, and the condition did not improve even after discontinuing SASP. Thus, therapy to enhance hepatic function was initiated. Histological analysis of liver biopsy specimens showed centrilobular spotty necrosis and periportal hepatitis. We diagnosed autoimmune hepatitis rather than drug-induced liver damage. Because of liver function deterioration, we initiated steroid treatment and rapid improvement was observed. Therefore, liver function should be carefully monitored during IFX administration for patients with genetic predispositions to autoimmune hepatitis, such as human leukocyte antigen-DR4.

Singapore medical journal. 2012;(8):508-11; quiz 512
Abstract
Gout is a chronic, progressive inflammatory disease with intermittent arthritic flares, which should not be regarded as a minor inconvenience or nuisance. It can be effectively controlled when the patient's serum urate level is reduced to less than 360 μmol/l (6 mg/dL) by consistent use of urate-lowering pharmacotherapy. Colchicine prophylaxis for gouty flares during titration of urate-lowering therapy has been underused. Holistic long-term management of gout must encompass patient education, evidence-based dietary advice, screening and aggressive treatment of comorbidities such as hypertension, diabetes mellitus, dyslipidaemia and renal impairment. Acute therapies for recurrent attacks with non-steroidal anti-inflammatory drugs, colchicine and/or corticosteroids should be used judiciously, especially in the elderly, due to the risk of toxicities. With appreciation of the underlying pathogenesis and artful use of the limited drug options, control of gout can be effectively achieved, bringing tremendous satisfaction to the patient and doctor.

Abstract
Aggressive fibromatosis (desmoid tumor) of the neck is rare. When feasible, surgery is the best treatment option. However, complete excision with negative margins is not possible in most cases because of the involvement of vascular and nervous structures. Also, surgery results in poor functional and aesthetic outcomes. Sometimes debulking surgery with positive margins is performed, but the anatomy of the neck is a challenge for oncologic surgeons, and recurrences are not uncommon. Radiotherapy is seldom employed for the same reasons. On the other hand, systemic treatment with chemotherapy, hormone therapy, and noncytotoxic agents such as nonsteroidal anti-inflammatory drugs (NSAIDs) has been used with good results. We report a case of inoperable aggressive fibromatosis of the neck that was successfully treated for about 21 months with a combination of chemotherapy and the NSAID indomethacin. As far as we know, this is the first reported use of a combination of chemotherapy and an anti-inflammatory drug in the treatment of aggressive fibromatosis of the neck. We also review the literature on cases of aggressive fibromatosis of the neck that have been reported over the past 12 years.

Acute kidney injury associated with metamizole sodium ingestion.
Hassan, K, Khazim, K, Hassan, F, Hassan, S
Renal failure. 2011;(5):544-7
Abstract
Metamizole sodium, a nonsteroidal anti-inflammatory drug, has been widely used in the last 100 years. Its efficacy as an analgesic and antipyretic is unquestionable. Only few cases of acute kidney injury (AKI) induced by metamizole sodium were reported in the medical literature. We report 11 adult patients with AKI that resulted from metamizole sodium ingestion. The data suggest a good prognosis in these cases of AKI. Renal biopsies, corticosteroids treatment, or renal replacement therapy seem to be not necessary. Hydration was sufficient to ensure spontaneous recovery.
