Causes of acute poisoning in adults: a retrospective study, in a hospital in Istanbul, Turkey

Aim  

Acute poisoning is one of the major topics in emergency medicine practices. Despite the recent developments in toxicology, technological advances and changing lifestyles reveal new factors, and poisoning cases remain to be a problem. All poisonings should be considered serious and independent from their clinical presentation at the time of admission. Identifying the cause and prompt initiation of treatment is life-saving. Causes of poisoning vary between countries and different regions of the same country. In the present study, cases admitted to the Emergency Department of Internal Medicine at Haseki Training and Research Hospital were evaluated and causes of acute poisoning were investigated.     

Is human kallikrein-11 in gastric cancer treated with surgery and adjuvant chemoradiotherapy associated with survival?

Human kallikreins (hKs) have been reported to be involved in human cancers, and several hKs are promising biomarkers of various cancers, such as prostate, ovarian, breast, and testicular cancer. In the present study, we aimed to evaluate the prognostic value of immunohistochemical expression of hK11 in patients with gastric cancer. The study included 55 (36 men and 19 women; 58 ± 10 years of mean age) patients with gastric cancer treated with surgery and adjuvant chemoradiotherapy. Tissue sections were evaluated immunohistochemically with a monoclonal anti-hK11 antibody. Of the 55 patients, 35 (63.6%) were hK11-positive and 20 (36.4%) were hK11-negative. Disease-free and overall survival rates were significantly higher in patients with hK11 positive than in those with hK-11 negative expression (24 months vs. 11 months, p: 0.043; 29 months vs. 13 months, p: 0.038, respectively). In conclusion, hK11 expression in gastric cancer appears to be associated with a better prognosis. hK11 may be a prognostic biomarker of gastric cancer. On the other hand, it is needed to elucidate the mechanisms underlying the regulation of hK11 expression in gastric cancer.     

3-Aminobenzamide,a Poly ADP Ribose Polymerase Inhibitor,Attenuates Renal Ischemia/Reperfusion Injury

Introduction. This study was designed to investigate whether 3-amino benzamide (3-AB), a poly (ADP-ribose) polymerase (PARP) inhibitor, has a protective effect on kidney injury induced by renal ischemia/reperfusion (I/R) by decreasing oxidative and nitrosative stress on renal dysfunction and injury. Materials and Methods. Thirty-two male Sprague-Dawley rats were divided into four groups: sham-operated, sham-operated + 3-AB, I/R, I/R + 3-AB. Rats were given 3-AB (100 mg/kg/day ip) 14 days prior to I/R. I/R and I/R + 3-AB groups underwent 60 min of bilateral renal ischemia followed by 6 h of reperfusion. After reperfusion, kidneys and blood were obtained for evaluation. Superoxide dismutase, glutathione peroxidase, malondialdehide, protein carbonyl content, and nitrite/nitrate level (NO_x) were determined in the renal tissue. Serum creatinine (S_Cr), blood urea nitrogen (BUN), and aspartate aminotransferase (AST) were determined in the blood. Additionally, renal sections were used for histological grade of renal injury. Results. 3-AB significantly reduced the I/R-induced increases in S_Cr, BUN, and AST. In addition, 3-AB markedly reduced elevated oxidative stress product, restored decreased antioxidant enzymes, and attenuated histological alterations. Moreover, 3-AB attenuated the tissue NO_x levels, indicating reduced NO production. Conclusions. 3-AB has beneficial effect on renal glomerular and tubular dysfunction in rats' kidneys subjected to I/R injury. Moreover, 3-AB has ameliorating effect on both oxidative stress and nitrosative stress of the kidneys, which correlated with histopathological evaluation.     

High-thoracic ultrasound-guided erector spinae plane block for acute herpes zoster pain management in emergency department

Herpes zoster is a painful, eruptive, viral condition occurring with reactivation in immunosuppressed individuals. The selection of an effective analgesic method in the acute phase of herpes zoster can decrease the incidence of postherpetic neuralgia by reducing neural sensitization. The erector spinae plane block has been reported to provide diffuse and effective analgesia in the cervical, thoracic, and lumbar regions. We report an effective decrease in pain with the application of the high-thoracic erector spinae plane block in the emergency department in a patient with herpes zoster pain in the cervicothoracic and shoulder region.     

A rare complication of a malleable penile prosthesis： migration to the thigh region

Dear editor, Here, we discuss an unusual prosthesis migration to the thigh region. Because the incidence of erectile dysfunction increases in par-allel with the prevalence of neurological, degenerative and vascular diseases among elderly men, the use of penile prostheses is common in this age group. Still, cylinder migration following the implantation of a malleable penile prosthesis is a very rare entity.     

Analgesic treatments in people with dementia - how safe are they? A systematic review

Introduction: People with dementia may be unable to verbally express pain and suffer from untreated pain. Use of analgesics in people with dementia has increased during the last decade, in particular opioid analgesics with high potential for adverse effects.

Areas covered: This article presents a systematic review of the current evidence for safety and tolerability of analgesic drugs from randomized controlled trials in people with dementia. Relevant trials were identified by a literature search in the EMBASE, MEDLINE, and Cochrane databases from inception to November 2018. The search included the main terms ‘dementia’ and ‘analgesic’ or their subterms, and was filtered to limit results to clinical trials.

Expert opinion: Although pain treatment is increasingly recognized as an important clinical issue in people with advanced dementia, there is currently a lack of evidence to support safety evaluations of commonly used analgesics in this group. To inform treatment decisions and enable care providers to appropriately monitor patients at risk of adverse effects, it is necessary to conduct well-designed clinical trials to investigate the relative efficacy and safety of analgesics in people with dementia, with particular emphasis on harmful effects of long-term opioid use as well as short-term use of nonsteroidal anti-inflammatory drugs.
