Abstract

Introduction: Knee osteoarthritis (OA) is a degenerative joint disease causing disability, especially in older adults. Flatfoot, marked by reduced medial arch height, alters lower limb biomechanics and may influence knee OA severity. Objective: To evaluate the association between foot arch, measured by Clarke’s angle, and knee OA severity based on the Kellgren-Lawrence (K-L) grading to provide clinical insight for guiding management decisions. Methods: A cross-sectional study of 57 knee OA patients at Siloam Karawaci Hospital was conducted. Clarke’s angle was measured using ink footprints, and K-L grading assessed radiological severity. Statistical tests included Kolmogorov-Smirnov, one-way ANOVA, and Kruskal-Wallis, with p < 0.05 considered significant. Results: Most participants were female (77.2%) with a mean age of 65.85 ± 9.69 years. OA severity was mostly mild to moderate (K-L 2 and 3). Flatfoot prevalence was 47.4%, and lower Clarke’s angles were significantly associated with higher K-L grades (p = 0.029). No significant differences in age or BMI were found across severity groups, though BMI trended higher with severity. Conclusion: Lower Clarke’s angle correlates with increased knee OA severity. Flatfoot may contribute to or result from OA progression. Further research is needed to clarify causation and inform management strategies.

Abstract

Background Piriformis syndrome (PS) is one causes of buttock and hip pain which is caused by pressure of sciatic nerves on piriformis muscle. PS is sometime misdiagnosed because of similar clinical signs and symptoms with other lower back pain diagnosis such as Hernia Nucleus Pulposus (HNP), Sacroiliac joint pain, facet joint pain. Gold standard diagnosis of PS is diagnostic block injection. However, provocative test and prolonged H reflex on EMG might be also standard diagnostic of PS.Aim Understand the sensitivity and specificity of provocative test and prolonged H reflex to diagnose PS.Method 72 patients with suspected PS who came to Neurology OPD in period of August- December 2017 were testing with physical examination (provocative test) and Electromyography test of H reflex. PS is diagnosed by positive diagnostic block injection. Data was proceeded with SPSS 20 version.Result 72 patients with buttock pain which diagnosed with PS were dominated by female gender than male with ratio 1:3 with housewives as majority of work. Most age groups were 48.6% elderly (age more than 60 years old). Provocative tests result of Freiberg, FAIR, Beatty, Pace Sign, Hip Abduction sensitivity were 52.30; 66.15; 53.84; 46.15; 55.32 and specificity were 100; 42.85; 71.42; 71.42; 57.14. While sensitivity and specificity of prolonged H reflex more than 1.86 msec were 69.23 and 28.59. Combination of 3 provocative tests (FAIR, Freiberg and Beatty) resulted highest sensitivity and specificity in this study as 71.42 and 100.Conclusion Provocative test and prolong H reflex can be supported diagnosis of PS. However both tests might not be comparable yet than diagnostic block injection as gold standard of PS. Combination of provocative test increased the sensitivity and specificity of provocative test than single test only.

Abstract

Background: Hemifacial spasm is a condition in which there are unilateral contractions of facial muscles. One of the most effective forms of treatment is botulinum toxin injections. However, this therapy only temporarily relieves symptoms, so repeated injections are necessary. This may place a significant economic strain on patients. Due to this, this study aims to see if low-dose botulinum toxin reduces the severity of hemifacial spasm. Objective: To find out whether there is an effect of low-dose botulinum toxin on the severity of hemifacial spasm. Methods: This study is a paired comparison test with a retrospective cohort design. Primary (HFS Score) and secondary (medical record) data was collected from hemifacial spasm patients at Siloam Hospitals Lippo Village Building B. Results: Data was collected from the 36 patients that fulfilled the inclusion and exclusion criteria. All patients were treated with 10 U or less of botulinum toxin. Results show that for HFS Clinical there was a decrease from a mean of 13,03 ± 2,077 to 6,44 ± 2,311 (p < 0,001), whereas HFS Subjective decreased from a mean of 401,53 ± 229,748 to 95,42 ± 151,607 (p < 0,001). Both components have a p-value < 0,001, making it statistically significant. Conclusion: Low-dose botulinum toxin affects the severity of hemifacial spasm in patients at Siloam Hospitals Lippo Village Building B.

Abstract

Postherpetic Neuralgia (PHN) is a persistent neuropathic pain following Herpes Zoster, particularly in the elderly. A case is reported of a 70-year-old man with PHN two months after HZ, experiencing burning and throbbing pain in the right T11–12 thoracic dermatomes with a pain scale of 8/10, paroxysmal in nature up to 10 times/day, triggered by touch, and disturbing sleep. The pain was unresponsive to gabapentin 1,800 mg/day and amitriptyline 12.5 mg/day. Two perineural injections of 5% dextrose reduced the pain to 6/10. At week 13, an ultrasound-guided erector spinae plane block was performed at the T12 level using 2% lidocaine (10 mL) and dexamethasone 5 mg, which rapidly reduced the pain from 6/10 to 0/10, with sustained improvement and discontinuation of medication. No complications were found. This case shows the erector spinae plane block as a safe, minimally invasive, and effective rescue therapy for refractory PHN.

Abstract

Pain is a common non-motor symptom in parkinsonism, often overlooked despite its significant clinical impact. The most common form is Parkinson's disease (PD), followed by secondary and atypical parkinsonisms such as PSP. Two cases presented with musculoskeletal-spinal pain as the chief complaint: a PD patient with upper back pain that improved after an erector spinae nerve block, and a PSP patient with lumbar facet pain that improved after an intra-articular steroid injection. Pain in parkinsonism can originate from muscles, bones, joints, discs, ligaments, fascia, or nerves, requiring careful evaluation. Both cases demonstrate the effectiveness of pain injection interventions in patients unresponsive to conservative therapy. Appropriate pain assessment and management are crucial to improving the quality of life of parkinsonism patients.

Abstract

Background: Only a small percentage of patients (2-10%) report pain symptoms during varicocele or post-varicocelectomy. The cause of the pain remains unclear and is still a matter of debate. Neither conservative nor surgical treatments provide a conclusive solution for pain. Nerve blocks can serve as a diagnostic and therapeutic tool in cases where the origin of pain is unknown. Case: A 30-year-old male presented with 4 year history of chronic scrotal pain, worsening over the past three weeks. The pain, rated 6/10 on the Numeric Rating Scale (NRS), was unrelieved by rest or analgesics and worsened at night and with prolonged sitting (NRS 7/10), significantly impacting daily activities. He had bilateral recurrent varicocele and underwent three varicocelectomies and ureteroscopy. Oral analgesics and neuropathic pain medications provided only temporary relief. The neurological examination revealed hyperalgesia in the distribution of the pudendal nerve. The imaging results were expected. Discussion: A notable reduction in pain was observed following an ultrasound-guided diagnostic pudendal nerve block with 2 mL of 2% lidocaine, confirming pudendal neuralgia related to varicocele or post-varicocelectomy. The pain is likely due to compression of the pudendal nerve branch by an enlarged pampiniform plexus.  Pulsed radiofrequency is utilized to provide longer-lasting pain relief. No complications were reported after the treatment.      Conclusion: Pudendal nerve blocks can alleviate scrotal pain and may be an alternative to genitofemoral and ilioinguinal nerve blocks. This is the first report of a successful pudendal nerve block for scrotal pain associated with varicocele or varicocelectomy.
