Hyperalgesia: An Emerging Iatrogenic Syndrome

2003

Clinical reports suggest that opioids, intended to abolish pain, can unexpectedly produce hyperalgesia. This paradoxical effect may be mechanistically related to tolerance induced by increasing doses of opioids. Two case reports illustrate a syndrome characterized by increasing pain pursued by escalating opioid doses, which results in a worsening of the clinical picture. Several experimental data may help explain the course of this challenging clinical condition. In escalating opioid doses rapidly, a risk of opioid-induced hyperalgesia should be recognized, as higher doses of opioids may stimulate rather than inhibit the central nervous system by different mechanisms. Alternative procedures…

2017 WSES guidelines for the management of iatrogenic colonoscopy perforation

2017

Abstract Iatrogenic colonoscopy perforation (ICP) is a severe complication that can occur during both diagnostic and therapeutic procedures. Although 45–60% of ICPs are diagnosed by the endoscopist while performing the colonoscopy, many ICPs are not immediately recognized but are instead suspected on the basis of clinical signs and symptoms that occur after the endoscopic procedure. There are three main therapeutic options for ICPs: endoscopic repair, conservative therapy, and surgery. The therapeutic approach must vary based on the setting of the diagnosis (intra- or post-colonoscopy), the type of ICP, the characteristics and general status of the patient, the operator’s level of experienc…

Pudendal nerve branch injury during radical perineal prostatectomy

2005

We report the first case of direct surgical injury to a pudendal nerve branch during radical perineal prostatectomy. A 65-year-old patient presented with typical symptoms of a pudendal nerve lesion after radical perineal prostatectomy. As the patient did not respond to conservative treatment, surgical exploration and exeresis of the injured sensory branch of the pudendal nerve was necessary, resulting in pain improvement. Urologic surgeons should be aware of the typical symptoms after iatrogenic injury to the pudendal nerve or its branches. Early diagnosis and neurosurgical intervention are important to obtain a more favorable outcome.

Risk factors in iatrogenic spinal cord injury

2017

Study design: In the last years, there has been a change in the aetiology of spinal cord injury. There has been an increase in the number of elderly patients with spinal cord injuries caused by diseases or medical procedures. Objective: The aim of this study is to investigate the frequency of the occurrence of iatrogenic spinal cord injury in our unit. The secondary aim is to study what variables can be associated with a higher risk of iatrogenesis. Methods: A retrospective, descriptive, observational study of patients with acute spinal cord injury admitted from June 2009 to May 2014 was conducted. The information collected included the patient age, aetiology, neurological level and grade o…

Phylogenetic reconstruction of HCV genotype 1b dissemination in a small city centre: The Camporeale model

2008

Several seroepidemiological population-based surveys carried out in Italy have shown a high prevalence of hepatitis C virus (HCV) infection. Camporeale (CP), a small Sicilian town with a 10.4% prevalence of HCV mostly genotype 1b, probably represents a specific context, since intravenous drug addiction, and sexual promiscuity are almost absent. In order to reconstruct the pattern of introduction and diffusion of HCV in this ecological niche, the NS5 genomic region of 72 HCV genotype 1 isolates (39 from CP and 33 collected throughout Sicily) was amplified and sequenced. Sequences were aligned and analyzed by BioEdit, PAUP and BEAST, and their molecular evolution compared. Thirty-eight HCV ge…

Secondary aortoduodenal fistula.

2008

Aorto-duodenal fistulae (ADF) are the most frequent aorto-enteric fistulae (80%), presenting with upper gastrointestinal bleeding. We report the first case of a man with a secondary aorto-duodenal fistula presenting with a history of persistent occlusive syndrome. A 59-year old man who underwent an aortic-bi-femoral bypass 5 years ago, presented with dyspepsia and biliary vomiting. Computed tomography scan showed in the third duodenal segment the presence of inflammatory tissue with air bubbles between the duodenum and prosthesis, adherent to the duodenum. The patient was submitted to surgery, during which the prosthesis was detached from the duodenum, the intestine failed to close and a ga…

Treatment of Iatrogenic Functional or Morphologic Bladder Loss

1988

From 1984 to 1986, six children from 4 to 13 years of age, received a bladder augmentation by ileocecal cystoplasty (Mainz-pouch technique) because of an iatrogenic functional or morphologic bladder loss. Indications for operation were incontinence due to the low bladder capacity or threat to the upper urinary tract due to ureteral obstruction or vesicorenal reflux. Two of the children had already undergone supravesical urinary diversion by sigmoid conduit. After a follow-up period of 2 to 19 months, (mean 11 months), five of the six children are completely continent. One boy with a known weak sphincter still has slight, but decreasing, enuresis nocturna in periods of complete filling of th…

Iatrogenic perforation during colonoscopy in the endoscopic suturing era: surgical emergency or endoscopic clinical practice?

Intentional replantation for the management of maxillary sinusitis.

2007

AIM: To present a case that emphasizes the importance of the use of intentional replantation as a technique to successfully treat a periapical lesion and an odontogenic maxillary sinusitis through the alveolus at the same time. SUMMARY: This case report presents a patient with odontogenic maxillary sinusitis secondary to periapical disease of a maxillary molar that had previously received root canal treatment. The molar was extracted, with drainage and rinsing of the maxillary sinus. The apices were resected extra-orally, the retrograde cavities prepared with ultrasound and retrograde fillings of silver amalgam placed. The tooth was then replanted. After 2 years, the patient was asymptomati…
