Hemimasticatory spasm is a rare neurologic disorder characterized by unilateral, paroxysmal involuntary contraction of the masticatory muscles. It can be confused with other unilateral facial spasms. In this report, we present two patients with hemimasticatory spasm who were initially misdiagnosed with other disorders. The first patient was a 54-year-old man with a 9-year history of right facial spasm. He underwent microvascular decompression, without benefit, at another hospital with the diagnosis of hemifacial spasm two years prior to presenting at our hospital.On examination, right masseter and temporalis muscles had irregular contractions with twitches and prolonged spasms. His brain magnetic resonance imaging was normal.He showed a good response to carbamazepine. The second case was a 60-year-old man presented with a 10-year history of jaw-closing movement. Previous treatment for temporomandibular joint disorder was ineffective. He was previously diagnosed as oromandibular dystonia at another hospital, and biperiden and diazepam treatment resulted in slight improvement. There was tonic contraction and hypertrophy of the left masseter. He improved with carbamazepine. These cases illustrate the importance of hemimasticatory spasm as differential diagnosis, and the good response to carbamazepine.

Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum (SCC). However, the clinical implications of this lesion are unclear and are not always consistent with ischemic infarctions. We performed this study to clarify the clinical and radiological implications in patients with SCC lesions. Methods: We retrospectively reviewed consecutive patients with MRIreported SCC changes between 2009 and 2012. We analyzed clinical and radiological findings, etiologies, cognitive impairment, and clinical outcomes. Results: We found 30 patients (16 females; mean 50.5 years) who had SCC lesions on MRI. Confusion was the most common clinical finding in 50% of cases. Cerebral infarction was the most common etiology (50%). The most consistent SCC changes on MRI were low signal in T1WI, high signal on T2WI and FLAIR, and high signal on DWI. We classified SCC lesions into in situ SCC lesions (SCC only) and multiple (SCC plus) lesions for patients with multiple lesions. The clinical symptoms of SCC only lesions were relatively mild. Cognitive functions were evaluated by Mini Mental State Examination (MMSE) and clinical dementia rating (CDR) scale at the time of discharge and patients with SCC only lesions showed less impaired cognition compared with those with SCC plus lesions. Clinical outcomes were evaluated by the modified Rankin scale at 1 month and patients with SCC only lesions revealed good clinical outcomes compared with those with SCC plus lesions. Conclusions: MRI-reported SCC lesions may have heterogeneous etiologies and present with various symptoms. The clinical course and outcome are relatively good, particularly in small isolated and oval shaped SCC lesions.

Background & Objective: Hiccups is a disabling condition of lateral medullary infarction (LMI). Unlike other symptoms of LMI, the anatomical lesions of hiccups are not well known. Few studies have evaluated the relationship between the lesional location of LMI and hiccups. We performed this study to correlate hiccups and magnetic resonance imaging (MRI)-based lesional location in pure LMI. Methods: Between January 1997 and February 2013, we identified 24 patients with pure LMI who presented with hiccups in addition to typical lateral medullary syndrome. Sixty six pure LMI patients without hiccups were included as a control group. Clinical and radiologic findings were compared between the two groups. MRI-identified lesions were classified rostrocaudally as rostral, middle and caudal, and horizontally as typical, ventral, large, lateral and dorsal. Results: The pure LMI patients with hiccups had significantly more frequent aspiration pneumonia (P = 0.001) and longer hospital stay (P = 0.03). The patients with hiccups significantly more often had dorsal rather than ventral lesion at horizontal levels (P = 0.012). But, there were no rostro-caudal differences at vertical levels (P = 0.162). Conclusions: We suggest that pure LMI associated with hiccups often locates in the dorsal medulla at horizontal correlation. This MRI-based comparative study has advanced the understanding of the neural substrate for hiccups in LMI, and indicates that hiccups become predictable when specific lesional locations in the lateral medulla are considered.

Myositis ossificans is a rare benign ossifying lesion in skeletal muscles which is commonly seen after trauma. However, it has been reported that myositis ossificans can be developed without any history of trauma and surgery. A 37-year-old female presented with a painful progressive swelling in her right femoral area, with no history of trauma or other diseases, which had been developed for 2 weeks. Initial X-rays were normal. An incision biospy specimen showed a lesion of fibroblastic tissue in which areas of osteoid and trabecular bone tissue, which was compatible with the early stage of myositis ossificans. The mass was excised totally and no signs of recurrence have been noted until now.

We compared the clinical efficacy of a short-term intervention of 308-nm excimer laser with that of narrow-band UVB (NBUVB) phototherapy for vitiligo patients to see the early response. Twenty-three symmetrically patterned patches of vitiligo on 8 patients were selected. Vitiligo patches on one side of the body were treated 2 times per week for a maximum of 20 treatments with the excimer laser, and NBUVB phototherapy was used on patches on the other side. Improvement (repigmentation) was assessed on a visual scale via serial photographs taken every five treatments and scored as follows: 0, or=75% improvement. At five treatments, the excimer laser-treated patches had an average score of 0.26, compared with 0.04 for patches treated with NBUVB phototherapy. A slightly higher repigmentation (p>0.05) in the excimer treated area was thus observed. At 10, 15, or 20 treatments, the differences between the average scores were significant: 0.83, 1.17, and 1.39 for the excimer-treated patches, and 0.17, 0.30, and 0.74 for the NBUVB pho-totherapy-treated areas (p<0.05). In conclusion, the 308-nm excimer laser appears to be more effective than NBUVB phototherapy, as it produces more rapid and profound repigmentation.

A 24-year old man with no history of trauma or other diseases presented with a tender growing lesion on the left upper arm for ten months' duration. The clinical appearance was similar to that of bulla. An excisional biopsy revealed multiple islands of shadow cells with small foci of basophilic cells at the periphery in deep dermis, along with areas of calcification and foreign body reaction within the tumor. In the dermis above the tumor, was collagen degeneration, with large spaces and numerous dilated blood vessels.

Background: Proximal-distal mismatch has emerged as a prominent concern in Dorr type A femoral morphology, prompting the exploration of short stems as promising alternatives to conventional stems. This study aimed to evaluate clinical and radiographic outcomes of total hip arthroplasty (THA) using short femoral stems in Dorr type A proximal femoral morphology with a minimum follow-up of 5 years. Methods: Patients with short femoral stems in Dorr type A between 2011 and 2017 were included. Patients with the Short Modular Femoral (SMF) stem and Metha stem were recruited and patients with a shortened tapered stem (Tri-Lock BPS) were matched by propensity score matching based on age, sex, body mass index, calcar to canal ratio, and diagnosis. Patient-reported outcomes and the presence of thigh pain were assessed at 5 years postoperatively. Revision rate, complication rate, and radiographic outcomes were also assessed and compared. Results: Twenty-two cases (81%) in the SMF stem and 43 cases (65%) in the Metha stem had more than 5 years of follow-up data available. The SMF stem showed a higher failure rate than the other 2 groups, with 18% requiring revision surgery in the SMF stem compared to 4.6% in the Metha stem, and 2.3% in the Tri-Lock BPS. The SMF stem showed considerable complications such as stem position change and lateral cortical hypertrophy with inferior clinical outcomes than the other 2 stem groups. When the Metha stem and the Tri-Lock BPS groups were compared, more intraoperative fractures were observed in the Metha stem, whereas stress shielding and anterior thigh pain were significantly more prevalent in the Tri-Lock BPS. Conclusions The SMF stem might be less reliable than previously reported, showing a high failure rate and increased radiologic complications. Thus, its use for THA in Dorr Type A femurs needs caution. On the other hand, the Metha stem showed comparable outcomes to the shortened tapered Tri-Lock BPS.

The ectopic eruption of teeth into the nasal cavity is a rare phenomenon. Ectopic tooth eruptions commonly occur in the palate and maxillary sinus, but have also been reported in the mandibular condyle, coronoid process, orbit, and nasal cavities. The clinical manifestations of intranasal teeth are quite variable; however, intranasal teeth can be an incidental finding during routine examination in patients without nasal discomfort. Herein we report a unique case of an intranasal ectopic tooth that erupted into the nasal cavity and caused significant nasal symptoms in an otherwise healthy patient. The intranasal tooth was removed endoscopically.
