Pain is a common symptom in older people. It is possible that pain is underreported in older persons due to an incorrect belief that it is an inevitable part of aging. Opioid analgesics are potent medications, with confirmed efficacy for the treatment of moderate to severe pain. These drugs are commonly used in older persons. However, there is insufficient evidence regarding safety of opioids in older patients. One of the reasons for this is the lack of randomized, controlled clinical trials. People of advanced age often have comorbidites and use other prescription drugs, as well as over-the-counter (OTC) compounds, thus making them more suceptible to the risk of interactions with opioids. Significant pharmacokinetic and pharmacodynamic changes that occur with advancing age increase the risk of adverse effects of opioids. There are also some discrepancies between guidelines, which recommend the use of lower doses of opioids in older patients, and the findings in the literature which suggest that pain is often undertreated in this age group. It seems that there are significant variations in the tolerability of different opioid analgesics in older people. Morphine, fentanyl, oxycodone and buprenorphine are still the preferred evidence-based choices for add-on opioid therapy for these patients. However, the safety and efficacy of other opioids in older patients, especially if comorbidities and polypharmacy are present, is still questionable. This review addresses the most important aspects of the use of opioids in older persons, focusing on pharmacokinetics, pharmacodynamics, adverse effects and interactions.

Ketamine as an old–new drug has a variety of clinical implications. In the last 30 years, ketamine has become popular for acute use in humans. Ketamine in standard doses is principally utilized for the induction and maintenance of surgical procedures. Besides its use in anesthesia and analgesia, recent studies have shown that ketamine has found a place in the treatment of asthma, epilepsy, depression, bipolar affective disorders, alcohol and heroin addiction. Ketamine primarily functions as a noncompetitive antagonist targeting the N-methyl-D-aspartate (NMDA) receptor, but its mechanism of action is complex. It is generally regarded as safe, with low doses and short-term use typically not leading to significant adverse effects. Also, ketamine is known as a powerful psychostimulant. During the past decade, ketamine has been one of the commonly abused drugs.

Objective To determine predicting value of otitis type, age, gender, ear suppuration, disease duration, mucosal changes, cholesteatoma spreading, labyrinthine fistula, size, localization of tympanic membrane perforation, type and stage of its retraction and ossicular chain disruption with sensorineural hearing loss in patients with tubotympanic otitis, cholesteatoma, and tympanic membrane retractions. Study Design Retrospective case review study. Setting Tertiary referral center. Patients Approximately 264 adult patients with unilateral chronic ear disease, 60 adult patients with tympanic membrane retractions, 78 with cholesteatoma, and 126 with tubotympanic otitis. Interventions Otomicroscopy, pure tone audiometry, impedancemetry were carried out preoperatively. Wall up, wall down tympanoplasty, or two-stage surgery was applied depending on pathology. Main Outcome Measure Bone conduction thresholds for 512 to 4,096 Hz. Results Mean values of bone conduction thresholds for frequencies 512 to 4,096 Hz were significantly higher in otitis groups than in healthy ears (p = 0.000), without differences between the groups. Ossicular disruption correlated with sensorineural hearing loss in cholesteatoma and tubotympanic otitis for all frequencies; long incus process destruction in tubotympanic ears showed strong negative correlation with sensorineural hearing loss for 512 to 2,048 Hz (linear regression coefficient, intercept was −2.84, −2.48, and −2.41; p = 0.0024, 0.0207, and 0.0076, respectively). Perforation size correlated with sensorineural hearing loss for 512 to 2,048 Hz in tubotympanic otitis (Log regression p = 0.0008, 0.0252, and 0.0267; odds ratio, 1.13, 1.11, and 1.06). Atelectasis correlated with sensorineural hearing loss for 4,096 Hz (p = 0.022). Conclusion Predictors for sensorineural hearing loss in chronic otitis are otitis itself, age, ossicular disruption, especially of long incus process, extensive labyrinthine fistula, perforation size, and type of retraction.

(1) Background: Surgical treatment of laryngeal carcinoma includes different types of laryngectomies with neck dissection. Surgical tissue damage triggers an inflammatory response, leading to the release of pro-inflammatory molecules. This increases reactive oxygen species production and decreases antioxidant defense mechanisms, leading to postoperative oxidative stress. The aim of this study was to assess the correlation between oxidative stress (malondialdehyde, MDA; glutathione peroxidase, GPX; superoxide dismutase, SOD) and inflammation (interleukin 1, IL-1; interleukin-6, IL-6; C–reactive protein, CRP) parameters and postoperative pain management in patients surgically treated with laryngeal cancer. (2) Methods: This prospective study included 28 patients with surgically treated laryngeal cancer. Blood samples were taken for the analysis of oxidative stress and inflammation parameters before the operative treatment and after the operative treatment (1st postoperative day and 7th postoperative day). The concentrations of MDA, SOD, GPX, IL-1, IL-6, and CRP in the serum were determined by coated enzyme-linked immunosorbent assay (ELISA). The visual analog scale (VAS) was used for pain assessment. (3) Results and conclusion: There was a correlation between oxidative stress and inflammation biomarkers and postoperative pain modulation in surgically treated patients with laryngeal cancer. Age, more extensive surgery, CRP values, and use of tramadol were predictors for oxidative stress parameters.

The aim of this study was to examine how ibuprofen and paracetamol prevent pain after cold-steel extracapsular tonsillectomy in children. Also, we examined the relation between age, gender, nausea, postoperative bleeding, antibiotic use, type of diet, and postoperative pain intensity and the type of administered analgesic. A prospective study was conducted on 147 children (95 males and 52 females, aged 7-17 years) who underwent tonsillectomy in the Clinical-Hospital Center “Dragiša Mišović” from January 1 to June 30, 2016. The degree of pain was measured using a visual analog scale (VAS). We did not observe any significant differences in postoperative nausea, hospitalization rate postoperative bleeding, and antibiotic use between the paracetamol and ibuprofen groups. A test of within-patient effects showed that VAS scores changed significantly during the postoperative follow-up period ( P = .00), but there were no significant differences between the groups ( P = .778). After 12 hours, 29.3% of the patients on paracetamol and 21.8% on ibuprofen were transferred to a soft diet; after 24 hours, 84.8% of the paracetamol group and 85.5% of the ibuprofen group were on a soft diet (χ2test, P < .05). There was a statistically significant correlation between VAS scores measured 4 hours after the surgery and the time of transference to the soft diet (Spearman ρ test, P < .001). The transfer to soft and normal diets was not significantly different between the 2 groups as assessed by the VAS scores (Pearson χ2test, P = .565).There is still no consensus on the most effective postoperative pain-control regiment after tonsillectomy. This study showed that satisfactory pain management was achieved equally with both paracetamol and ibuprofen.
