Multiarticular chronic tophaceous gout with severe and multiple ulcerations: a case report

<p>Abstract</p> <p>Introduction</p> <p>Gout is a common inflammatory arthritis caused by articular precipitation of monosodium urate crystals. It usually affects the first metatarsophalangeal joint of the foot and less commonly other joints, such as wrists, elbows, knees and ankles.</p> <p>Case presentation</p> <p>We report the case of a 75-year-old Caucasian man with tophaceous multiarticular gout, soft-tissue involvement and ulcerated tophi on the first metatarsophalangeal joint of the left foot, on the first interphalangeal joint of the right foot and on the left thumb.</p> <p>Conclusion</p> <p>Ulcers due to tophaceous gout are currently uncommon considering the positive effect of pharmaceutical treatment in controlling hyperuricemia. Surgical treatment is seldom required for gout and is usually reserved for cases of recurrent attacks with deformities, severe pain, infection and joint destruction.</p

Jejunal Diverticular Perforation due to Enterolith

Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life-threatening and require early surgical treatment. Small bowel perforation secondary to jejunal diverticulitis by enteroliths is rare. The aim of this study was to report a case of small intestinal perforation caused by a large jejunal enterolith. An 86-year-old woman was admitted with signs of diffuse peritonitis. After initial fluid recovery the patient underwent emergency laparotomy. The surgery showed that she had small bowel diverticular disease, mainly localized in the proximal jejunum. The peritonitis was due to intestinal perforation caused by an enterolith 12 cm in length, localized inside one of these diverticula. The intestinal segment containing the perforated diverticulum with the enterolith was removed and an end-to-end anastomosis was done to reconstruct the intestinal transit. The patient recovered well and was discharged from hospital on the 5th postoperative day. There were no signs of abdominal pain 1 year after the surgical procedure. Although jejunal diverticular disease with its complications, such as formation of enteroliths, is difficult to suspect in patients with peritonitis, it should be considered as a possible source of abdominal infection in the elderly patient when more common diagnoses have been excluded

Multifocal pyomyositis and meningitis after bone marrow biopsy in a diabetic patient

Primary or tropical pyomyositis is a subacute infection of the skeletal muscle complicated by abscess formation. The disease is rare in the temperate climates and often misdiagnosed because of the vague clinical presentation. We herein report a case of a 38-year-old diabetic patient with a history of recent bone marrow biopsy presented multifocal primary pyomyositis complicated by meningitis

Silibinin Effect on Fas/FasL, HMGB1, and CD45 Expressions in a Rat Model Subjected to Liver Ischemia-Reperfusion Injury

Purpose: We investigated the hepatoprotective effect of Silibinin (SLB) to ischemia-reperfusion (I/R) rat model, by evaluating the histological expression of the tissue markers Fas/FasL, HMGB-1 and CD45, and SLB pharmacokinetics. Methods: Seventy-three Wistar-type male rats were randomized in 11 groups: Sham control group (open-close laparotomy); four I/R control groups (laparotomy, 45 min vascular occlusion, reperfusion, euthanasia after 60, 120, 180, and 240 min); four SLB (Si) groups (laparotomy, 45 min vascular occlusion, IV administration of SLB, reperfusion, euthanasia after 60, 120, 180, and 240 min); two SLB pharmacokinetics (PK) groups (IV administration of SLB, euthanasia after 45 and 240 min). Results: Fas/FasL increased with reperfusion time in I/R control groups and decreased in the Si groups, reaching, respectively, the highest and lowest values at 240 min of reperfusion (p &lt;.0001). HMGB1 and CD45 increased with time in the I/R control groups up to 240 min and decreased in the Si groups, approaching zero expression after 180 and 60 min, respectively. Pharmacokinetic data showed higher liver accumulation and slower plasma elimination of SLB in ischemic animals. Conclusions: The hepatoprotective effect of SLB was demonstrated through the reduction of the expression of Fas/FasL, HMGB-1 and CD45 in liver tissue under I/R conditions, and in the pharmacokinetic study. The results document the efficacy of silibinin in the protection of the liver, and are particularly encouraging for its use in hepatic surgery. © 2017, Copyright © 2017 Taylor &amp; Francis Group, LLC
