Sufficient explanation of management affects patient satisfaction and the practice of post-treatment management in spinal pain, a multicenter study of 1007 patients.

BACKGROUND: Spinal pain is most common symptom in pain clinic. In most cases, before the treatment of spinal pain, physician explains the patient's disease and treatment. We investigated patient's satisfaction and physician's explanation related to treatments in spinal pain patients by questionnaires. METHODS: Anonymous questionnaires about physician's explanation and patient's satisfaction in each treatment and post-treatment management were asked to individuals suffering from spinal pain. Patients who have spinal pain were participated in our survey of nationwide university hospitals in Korea. The relationships between patient's satisfaction and other factors were analyzed. RESULTS: Between June 2016 and August 2016, 1007 patients in 37 university hospitals completed the questionnaire. In the statistical analysis, patient's satisfaction of treatment increased when pain severity was low or received sufficient preceding explanation about nerve block and medication (P < 0.01). Sufficient explanation increased patient's necessity of a post-treatment management and patients' performance rate of post-treatment management (P < 0.01). CONCLUSIONS: These results show that sufficient explanation increased patients' satisfaction after nerve block and medication. Sufficient explanation also increased the practice of patients' post-treatment management.

A case of neuromyelitis optica misdiagnosed as cervicogenic headache.

Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system associated with longitudinally extensive myelitis and optic neuritis. It is characterized by relapses that lead to blindness and paralysis sequelaes. But, this is rare disease; therefore high clinical suspicion for a correct diagnosis and proper examinations are not easy. However, early diagnosis is essential to prevent sequelae. We report the case of NMO with headache. A 30-year male patient who suffered headache visited our pain clinic because of aggravated pain despite treatment. The cause of the pain was revealed as NMO by more detailed previous history and examination.

Administration of four different doses of gabapentin reduces awakening from breakthrough pain and adverse effects in outpatients with neuropathic pain during the initial titration.

BACKGROUND: Gabapentin is a safe and well-tolerated anticonvulsant with a wide therapeutic index, and it is used for neuropathic pain. The aim of this study was to compare previous dosing methods with the administration of four different doses of gabapentin while maintaining the same maximum daily dose for the safe administration of high doses of the medication. METHODS: THE SUBJECTS WERE OUTPATIENTS WITH VARIOUS NEUROPATHIC PAIN SYNDROMES, WITH AT LEAST TWO OF THE FOLLOWING SYMPTOMS: allodynia, burning pain, shooting pain, or hyperalgesia. The TID group received equal doses of gabapentin 3 times per day, while the QID group received 4 different doses of gabapentin per day. The pain score, frequency of breakthrough pain (BTP), severity and the duration of pain, sleep disturbance due to nocturnal pain, and adverse effects were recorded each day. RESULTS: The average daily pain score and sleep disturbance were significantly reduced in the QID group between days 3 and 10 of the experiment. The adverse effects of the medication were also reduced in the QID group. However, the frequency of BTP and severity and duration of pain were not significantly different between two groups. CONCLUSIONS: Administration of 4 different doses of gabapentin during the initial titration in outpatients with neuropathic pain resulted in a significant reduction in awakening from breakthrough pain and a reduction in the adverse effects of the medication.

Non Surgical Treatment of Eagle's Syndrome - A Case Report -.

Eagle's syndrome is a disease without a clear lesion that is associated with repeated episodes of pharyngalgia, odynophagia, the sensation of a foreign body in the pharynx, tinnitus, and otalgia in which patients displaying these types of symptoms must be given a differential diagnosis. It is known to be characterized by styloid process elongation or increasing compression to adjacent anatomical structures through stylohyoid ligament calcification. In serious cases, continuous pressure to the carotid artery can lead to a stroke. Diagnosis is confirmed through clinical symptoms, radiological findings, and physical examinations. The most common type of treatment consists of a surgical excision of elongated styloid process. Nonetheless, this study presents a case of treating Eagle's syndrome with conservative management.

Inadvertent Dural Puncture during Caudal Approach by the Introducer Needle for Epidural Adhesiolysis Caused by Anatomical Variation.

There have been reports of abnormalities in the lumbosacral region involving a lower-than-normal termination of the dural sac, which is caused by disease or anatomical variation. Inadvertent dural puncture or other unexpected complications can occur during caudal epidural block or adhesiolysis in patients with these variations, but only a small number of case reports have described this issue. We report a case of dural puncture by the introducer needle before attempting caudal epidural adhesiolysis, which occurred even though the needle was not advanced upward after penetrating the sacrococcygeal ligament. Dural puncture was caused by a morphological abnormality in the lumbosacral region, with no pathological condition; the dural sac terminal was located more distally than normal. However, dural puncture could have been prevented if we had checked for such an abnormality in the magnetic resonance imaging (MRI) taken before the procedure.

Spinal arteriovenous malformation masquerating zoster sine herpete.

Zoster sine herpete (ZSH) is difficult to diagnosis during an acute period due to the absence of the characteristic zosteriform dermatomal rash; therefore, progression to postherpetic neuralgia is more common than typical zoster. In addition, misdiagnosis of other neuropathic pain as ZSH is common in clinical situations. Here, we report a case of spinal arteriovenous malformation that mimics ZSH. This is a rare condition; therefore, high clinical suspicion for a correct diagnosis and proper examination are not easy. However, early diagnosis and definitive treatment are essential to prevent neurologic deficit and mortality.

Efficacy of stellate ganglion block in cholinergic urticaria with acquired generalized hypohidrosis.

Cholinergic urticaria with acquired generalized hypohidrosis, and its pathophysiology is not well known. Autoimmunity to sweat glands or to acetylcholine receptors on sweat glands has been mentioned as one of the possible etiologies. Systemic steroid therapy, antihistamines, anticholinergics, and avoidance of the stimulatory situations are recommended for treatment. We experienced a case of cholinergic urticaria with acquired generalized hypohidrosis in a patient who had no other associated disease, and the symptoms eased after repeated bilateral stellate ganglion block. Stellate ganglion block normalized the elevated sympathetic tone and may relieve symptoms in patients with this condition.

Management of complex regional pain syndrome type 1 with total spinal block.

Complex regional pain syndrome (CRPS) is a painful and disabling disorder that can affect one or more extremities. Unfortunately, the knowledge concerning its natural history and mechanism is very limited and many current rationales in treatment of CRPS are mainly dependent on efficacy originated in other common conditions of neuropathic pain. Therefore, in this study, we present a case using a total spinal block (TSB) for the refractory pain management of a 16-year-old male CRPS patient, who suffered from constant stabbing and squeezing pain, with severe touch allodynia in the left upper extremity following an operation of chondroblastoma. After the TSB, the patient's continuous and spontaneous pain became mild and the allodynia disappeared and maintained decreased for 1 month.
