Purpose:
To confirm that the phaco chop method using an illuminated chopper (iChopper; Oculight, Seongnam, Korea) can reduce cataract surgery complications, and that even beginners can safely and effectively perform phaco chop.
Methods:
We retrospectively analyzed the medical records of the first 30 phaco chop cases using illuminated chopper of four cataract surgeons. Four ophthalmologists had a variety of empirical backgrounds, from those who have experienced more than 10,000 cataract surgery, to beginners who have experienced 20 cataract surgery.
Results:
Of the total 120 eyes, two eyes (1.67%) had posterior capsule rupture. The chopping method was changed from phaco chop to stop and chop in three eyes (2.5%) including one eye with brown cataract with pseudoexofoliation syndrome and two eyes with nuclear opacity grade ≥5.
Conclusions
The rates of posterior capsule rupture of phaco chop using an illuminated chopper were very low in four surgeons with various experiences and who became proficient shortly in phaco chop.

African tick-bite fever (ATBF), caused by Rickettsia africae, is the second most frequent cause of fever after malaria in travelers returning from Southern Africa. As the Korean outbound travelers are increasing every year, tick-borne rickettsial diseases as a cause of febrile illness are likely to increase. We describe a febrile Korean returning traveler who showed two eschars after visiting the rural field in Manzini, Swaziland. We performed nested polymerase chain reaction using the eschar and diagnosed the patient with ATBF. He was treated with oral doxycycline for 7 days, and recovered without any complications. We believe that the present case is the first ATBF case diagnosed in a Korean traveler.

Purpose:
This study analyzed the effects of non-damaging retinal laser therapy (NRT) in patients with chronic central serous chorioretinopathy.
Methods:
A retrospective study was conducted on patients with chronic central serous chorioretinopathy who were undergoing follow-up with NRT from November 2016 to February 2018. NRT was performed in patients who underwent intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection at least two times with no improvement in visual acuity and a reduced amount of subretinal fluid. Before and after treatment, logMAR best-corrected visual acuity (BCVA) evaluation and subretinal fluid (SRF) according to thickness measurements of the macula determined from optical coherence tomography imagery were performed over a period of at least 6 months.
Results:
Eighteen eyes of 18 patients (11 male and 7 female) with chronic central serous retinopathy were treated with NRT. The mean age of patients was 54.6 ± 13.19 years old and the mean duration of follow-up was 9.75 ± 3.20 months. The central macular thickness decreased from 375 to 246 nm (p < 0.001) and BCVA improved from 0.48 to 0.40 (p = 0.028). SRF completely resolved in 55.56% of the patients after NRT.
Conclusions
In patients with chronic central serous chorioretinopathy, which did not improve even after intravitreal anti-VEGF injection, NRT is a relatively safe and effective treatment.

In tetraplegia patients, activities of daily living are highly dependent on the remaining upper limb functions. In other countries, upper limb reconstruction surgery to improve function has been applied to diverse cases, but few cases have been reported in Korea. The current authors experienced a case of posterior deltoid-to-triceps tendon transfer and rehabilitation in a complete spinal cord injury with a C6 neurologic level, and we introduce the case-a 36-year-old man-with a literature review. The patient's muscle strength in C5 C6 muscles were normal, but C7 muscles were trace, and the Spinal Cord Independence Measure III (SCIM III) score was 24. The tendon of the posterior deltoid was transferred to the triceps brachii muscle, and then the patient received comprehensive rehabilitative treatment. His C7 muscle strength in the right upper extremity was enhanced from trace to fair, and his SCIM III score improved to 29.

OBJECTIVE: To evaluate the effect of post-stroke depression (PSD) on rehabilitation outcome and to investigate the risk factors of PSD, especially, the role of caregivers type (family or professional) in subacute stroke patients. METHODS: Two hundred twenty-six stroke patients were enrolled retrospectively. All the subjects' basic characteristics, Korean version of the Beck Depression Inventory (K-BDI), Korean version of the Modified Barthel Index (K-MBI), and the modified Rankin Scale (mRS) were recorded when the patient was transferred into the Department of Rehabilitation Medicine and at the time of discharge. The results were statistically analyzed by using SPSS ver. 20.0. RESULTS: The patients' K-BDI score showed a significantly negative association with K-MBI at discharge (beta=-0.473, p<0.001) and a significantly positive association with the mRS score at discharge (beta=0.316, p<0.001). Patients with lesions on the left hemisphere (odds ratio [OR], 3.882; 95% confidence interval [CI], 1.726-8.733) and professional caregiver support (OR, 0.028; 95% CI, 0.012-0.065) had a higher rate of depression. CONCLUSION: Depression was prevalent in stroke patients, and it had a negative effect on patients' functional outcome. Patients who had a lesion on the right hemisphere had less depression. The type of caregiver was related to the incidence of subacute PSD, and family caregivers were found to lower the frequency of stroke patients' depression.

OBJECTIVE: To determine overall handgrip strength (HGS), we assessed the short-term change of HGS after trigger point injection (TPI) in women with muscular pain in the upper extremities by comparison with established pain scales. METHODS: The study enrolled 50 female patients (FMS with MPS group: 29 patients with combined fibromyalgia [FMS] and myofascial pain syndrome [MPS]; MPS group: 21 patients with MPS) who presented with muscular pain in the upper extremities at Konyang University Hospital. In addition, a total of 9 healthy women (control group) were prospectively enrolled in the study. We surveyed the three groups using the following established pain scales: the Fibromyalgia Impact Questionnaire (FIQ), the 36-Item Short Form Health Survey (SF-36), and the Short Form McGill Pain Questionnaire (MPQ). HGS was measured in both hands of study participants using a handgrip dynamometer. We performed TPI (0.5% lidocaine, total 10 mL, injected at the pain site of upper extremities). After 20 minutes, we remeasured the patient's HGS and MPQ score. RESULTS: ANOVA analysis was conducted among groups. Based on Tukey multiple comparison test, the majority of FIQ and SF-36 subscales, total FIQ and SF-36 scores, MPQ and HGS were significantly different between FMS with MPS and the other groups. There was no statistically significant difference between MPS and control groups. Higher HGS was positively associated with enhanced physical function, negatively associated with total FIQ and MPQ scores, and positively associated with the total SF-36 score calculated using Spearman correlation. Post-TPI MPQ decreased and HGS increased. In patient groups, a negative correlation was found between MPQ and HGS. CONCLUSION: The HGS test might potentially be a complementary tool in assessing the short-term treatment effects of women with muscular pain in the upper extremities.

Spinal cord injury (SCI) without radiographic abnormality (SCIWORA) is estimated to account for 1-9% of the occurrence of SCI. Of these, cervical SCIWORA in children is common, but thoracic SCIWORA delayed onset in adult is much less common. We experienced a case of 38-years old male patient with lower extremity weakness; he had fallen down a week earlier before the investigation. At the time of admission, motor grade was 4 with voiding incontinence and ambulated with cane. He presented progressive weakness from G4 to G3 and hypoesthesia was below T8 dermatome and ambulated with wheelchair. Whole spine and lumbar MRI findings showed no abnormality and electrodiagnostic findings showed normal NCS, however, abnormal SEP on both the tibial nerves. After steroid therapy and proper rehabilitation program for 2 weeks, lower extremity strength was improved from G4 to G3, voiding was continent, and ambulation reached cane gait.

PURPOSE: To evaluate the clinical efficacy and histopathological tolerance of 2-octyl cyanoacrylate versus conventional suture materials for eyelid wound closure in rabbits. METHODS: We performed an experimental study on 16 eyes of eight New Zealand albino rabbits. Eyelid incisions of 15 mm were done 4mm from the upper eyelid margin in both eyes. The eyes of the rabbits were divided into two groups: eyelid incisions of the right eye were closed by a 2-octyl cyanoacrylate adhesive (group A) and eyelid incisions of the left eye were closed by 7-0 nylon sutures (group B). At 1, 2, 4, and 8 weeks after surgery, the rabbits were macroscopically examined and then sacrificed. The specimens of their eyelid tissues were stained by a hematoxylin and eosin stain and Masson-trichrome stain, and were observed under microscope. RESULTS: Both eyelid surgical closure methods were found to be equally efficacious in fixing the eyelids of groups A and B, and their clinical efficacy was similar. Histopathological findings of the hematoxylin and eosin stain of group A showed less inflammatory infiltration than group B at 2 weeks. There were no significant histopathological differences between the two groups at 1, 4, and 8 weeks. The degree of fibrosis of the Masson-trichrome stain was similar between the two groups at 8 weeks. CONCLUSIONS: The 2-octyl cyanoacrylate adhesive proved to be an effective eyelid closure method and was very well tolerated by the skin surface. 2-Octyl cyanoacrylate could be used as an alternative tissue adhesive for eyelid wound closure along with conventional suture materials.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.
