  • We investigated the effect of oral analgesics for patients with cancer pain, retrospectively. One hundred forty six cases were randomly selected during the period between 1986 to 1990. These patients were treated with Tramadol (n=31), Tylenol III(Acetaminophen plus codein phosphate, n=44) or MS-Contin (n=71). partial to complete pain relief as achieved accord to each durg group at 67.8, 68.2 and 76.1% respectively. Minimal side effects were noted in a few patients. Our results show encouraging possibilities for pain control in cancer patients. However, futher studies should be done to find more effective cancer pain management by oral analgesics.

  • Nefopam, a centrally acting analgesic, has been used to control postoperative pain. Reported adverse effects are anticholinergic, cardiovascular or neuropsychiatric. Neurologic adverse reactions to nefopam are confusion, hallucinations, delirium and convulsions. There are several reports about fatal convulsive seizures, presumably related to nefopam. A 71-year-old man was admitted for surgery for a lumbar spinal stenosis. He was administered intravenous analgesics : ketorolac, tramadol, orphenadrine citrate and nefopam HCl. His back pain was so severe that he hardly slept for several days; he even needed morphine and pethidine. At 4 days of administration of intravenous analgesics, the patient suddenly started generalized tonic-clonic seizures for 15 seconds, and subsequently, status epilepticus; these were not responsive to phenytoin and midazolam. After 3 days of barbiturate coma therapy the seizures were controlled. Convulsive seizures related to nefopam appear as focal, generalized, myoclonic types, or status epilepticus, and are not dose-related manifestations. In our case, the possibility of convulsions caused by other drugs or the misuse of drugs was considered. However, we first identified the introduced drugs and excluded the possibility of an accidental misuse of other drugs. Physicians should be aware of the possible occurrence of unpredictable and serious convulsions when using nefopam.

  • The stem of Lindera obtusiloba (Lauraceae), has been widely used as a traditional medicine for the treatment of abdominal pain, bruise and hepatocirrhosis. In the present study, antinociceptive and sedative properties of the methanol extract of L. obtusiloba (MLO) were evaluated. MLO demonstrated strong and dose-dependent antinociceptive activities on various experimental pain models including thermal nociception and chemical nociception, compared to tramadol and indomethacin, reference drugs. In combination test using naloxone, the diminished analgesic activity of MLO was observed, indicating the relation with opioid receptor. Moreover, MLO also decreases pentobarbital-induced sleep latency and increases sleeping time suggesting its hypnotic and sedative action. The present results indicate that MLO could be used as valuable antinociceptive and sedative agent for the treatment of various diseases.

  • Herpes zoster most commonly occurs in elderly patients, and usually affects sensory neurons. Therefore, its characteristic symptoms are segmental pain, itching, and sensory changes in the affected areas. A 71-yr-old woman experienced painful herpetic rash on the right cervical 2-4 dermatomes for 16 days. Two days after the onset of the rash, she was diagnosed with herpes zoster, and prescribed 250 mg famciclovir three times a day for 7 days, pregabalin 150 mg twice a day, and tramadol 150 mg once a day for 14 days, by a dermatologist. Despite medication, her pain was rated at an intensity of 6/10 on the numeric rating scale. In addition, she complained of severe itching sensation on the affected dermatomes. Superficial cervical plexus block (SCPB) was performed at the right C4 level with 15 ml 0.5% lidocaine plus triamcinolone 30 mg. Five days after the procedure, pain and itching completely disappeared. SCPB may be an effective option for the treatment of acute pain and itching arising from herpes zoster, and for the prevention of postherpetic neuralgia.

  • The identification step of raw drug materials is an indispensible procedure in the GMP manufacturing process within the pharmaceutical industry. However, wet chemistry methods for identification of drug materials, used by the various Pharmacopeia are time-consuming and expensive steps. In this paper, near-infrared spectroscopy (NIRS) has been developed for identifying eleven drug substances including calcium pantothenate, cefaclor, cefoperazone, cephradine, dextromethorphan, ehtambutol, nicotinamide, pyrozinamide, tramadol, vitamin C, and vitamin E. Also the aim of ths work is to consturct a new algorithm for calibration model using soft independence modeling of class analogy (SIMCA) with Malinowskis Indicator Function (IND), which is used for finding the number of principal components of each class of the SIMACA model. The use of NIR technique with pattern recognition to qualify raw materials can make it possible to monitor process in real time as well as to control all procedures in the pharmaceutical industry. As the result, the samples identified of 183 different batches from 11 different compounds were separated clearly by SIMCA with 2nd derivative spectra in the NIR region of 1100∼2400 nm.

  • Serotonin syndrome (SS) is a potentially life-threatening condition that is caused by the administration of drugs that increase serotonergic activity in the central nervous system. We report a case of serotonin syndrome in a patient with chronic pain who was taking analgesic drugs. A 36-year-old female with chronic pain in the lower back and right buttock area had been taking tramadol hydrochloride 187.5 mg, acetaminophen 325 mg, pregabalin 150 mg, duloxetine 60 mg, and triazolam 0.25 mg daily for several months. After amitriptyline 10 mg was added to achieve better pain control, the patient developed SS, which was mistaken for psychogenic nonepileptic seizure. However, her symptoms completely disappeared after discontinuation of the drugs that were thought to trigger SS and subsequent hydration with normal saline. Various drugs that can increase serotonergic activity are being widely prescribed for patients with chronic pain. Clinicians should be aware of the potential for the occurrence of SS when prescribing pain medications to patients with chronic pain.

  • Purpose: There is a strong correlation between trauma and pain. Pain increases the rate of depression, posttraumatic stress disorder, and even mortality in trauma patients. Methods: This institution-based, provider-blinded and patient-blinded, observational study was conducted among trauma patients treated at Tikur Anbessa Specialized Hospital. Over the course of 3 months, this study included patients who had no prior pain management at other hospitals before presentation, and who presented within 24 hours of the traumatic event. Results: Of the 74 patients evaluated, none of the patients had their pain level scored. The researcher-provided pain scale showed a severe subjective pain score for 79.7% of the patients and a severe functional activity score for 59.5% of the patients. Analgesia was provided at an average of 55.4 minutes after presentation and all patients received either diclofenac or tramadol. Satisfactory pain reduction after analgesia was 28.8% for patients initially complaining of severe pain, 54.6% for moderate pain, and 66.7% for mild pain, with the difference being statistically significant (P<0.05). Forty percent of patients discharged home received no analgesia after the first dose provided upon presentation. Conclusions: Pain scoring was nonexistent during the course of the study. The poor utilization rate of analgesia combination and opioids led to unsatisfactory pain outcomes in patients evaluated and followed for 24 hours after presentation.

  • A 14-year-old intact male captive leopard (Panthera pardus) first presented with a focal alopecic lesion on the dorsal aspect of the distal one-third of its tail. Although itraconazole was administered, the lesion progressed deeper and became ulcerated due to self-trauma. Due to the wild nature of the leopard, daily dressing of the wound and replacing the bandages without anesthesia became too dangerous, and amputation became necessary. A postoperative tissue sample was submitted for histopathological examination, and tramadol, amoxicillin/clavulanate, and gabapentin were administered. In the days following the amputation, the leopard's appetite significantly decreased, and the patient passed away 18 days later. Histopathological examination of the specimen revealed well-differentiated squamous cell carcinoma (SCC). In hindsight, had more cells been collected by a fine-needle aspirate (FNA) biopsy or had additional FNA biopsies been performed, SCC might have been diagnosed based on its cytological features rather than delayed histopathological findings. The current study highlights the critical reasons why clinicians may often misdiagnose SCC and the importance of being more aware of potential tumors in ulcerative lesions, which are often incorrectly treated as infectious skin diseases. This is also the first report of cutaneous SCC in a leopard.

  • In order to minimize such adverse drug reactions, governments and international organs have been on the watch for them. Also in South Korea, a system has been established in order that adverse drug reactions may be reported to Korea Food and Drug Administration(KFDA). This study is to analyze drugs to cause adverse reactions, the adverse reactions and patients concerned on the authority of the data of Korea FDA, which is expected to be the preliminary data on preventable adverse reactions. This study was conducted on the 74,037 cases of adverse drug reactions reported to Korea FDA between January 2007 and June 2010. Fentanyl, iopromide and tramadol caused adverse reactions with high frequencies. Oseltamivir showed a high frequency between 2009 and 2010 due to the influence of the new influenza A. Also, OTC drugs accounted for approximately 5% of the adverse reactions. In 2009, adverse drug reactions remarkably increased (2,106 cases; 10.1%) in infants and children due to the new influenza-A(H1N1). The patients aged between 31 and 64 accounted for approximately 55% during the given period. There was no significant intergender difference. In relation to regions, the adverse reactions most frequently occurred in the gastrointestinal system and the integumentary system for three and half years. In addition to anticancer drugs and immunosuppressive drugs that are known to cause adverse reactions frequently, not a few of OTC drugs and external preparations caused such reactions. In particular, the drugs containing specific ingredients caused adverse reactions more frequently than others from 2007 until the first half of 2010. It is advisable for prescribers to acquaint themselves with such adverse reactions and to prescribe drugs other than them. They also have need to sensibly cope with adverse drug reactions just in case they have no substitute drugs. In addition, patients also need to be trained to understand possible adverse reactions in order that they can sensibly accommodate them or choose healthcare services. The results of this study are expected to be helpful to minimize adverse drug reactions.

  • Chronic pain is a multifactorial condition with both physical and psychological symptoms, and it affects around 20% of the population in the developed world. In spite of outstanding advances in pain management over the past decades, chronic pain remains a significant problem. This article provides a mechanism- and evidence-based approach to improve the outcome for pharmacologic management of chronic pain. The usual approach to treat mild to moderate pain is to start with a nonopioid analgesic. If this is inadequate, and if there is an element of sleep deprivation, then it is reasonable to add an antidepressant with analgesic qualities. If there is a component of neuropathic pain or fibromyalgia, then a trial with one of the gabapentinoids is appropriate. If these steps are inadequate, then an opioid analgesic may be added. For moderate to severe pain, one would initiate an earlier trial of a long term opioid. Skeletal muscle relaxants and topicals may also be appropriate as single agents or in combination. Meanwhile, the steps of pharmacologic treatments for neuropathic pain include (1) certain antidepressants (tricyclic antidepressants, serotonin and norepinephrine reuptake inhibitors), calcium channel ${\alpha}2-{\delta}$ ligands (gabapentin and pregabalin) and topical lidocaine, (2) opioid analgesics and tramadol (for first-line use in selected clinical circumstances) and (3) certain other antidepressant and antiepileptic medications (topical capsaicin, mexiletine, and N-methyl-d-aspartate receptor antagonists). It is essential to have a thorough understanding about the different pain mechanisms of chronic pain and evidence-based multi-mechanistic treatment. It is also essential to increase the individualization of treatment.
