Melorheostosis is a rare disease entity of bone with an etiology and pathogenesis. It cause pain and stiffness in an affected limb, and dense bone formation along the side of bone resembles the flow of candle dripping. Two cases of the disease involving left hand and wrist, and right lower leg are reported with the review of literature.

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

Cystinuria is an autosomal recessive inherited defect in renal tubular reabsorption of four amino acids, cystine, ornithine, lysine and arginine. Homozygotes were identified by the formation of urinary tract calculi composed of cystine and by gross hyperexcretion of above mentioned four amino acids. Urinary tract calculi composed primarily of cystine are rare in adults and children. These are usually pure and found exclusively in patients with cystinuria. Herein we report on a 4 and 3/12 years old male child with a right renal stone composed primarily of cystine which was confirmed by chemical analysis method postoperatively. After discharge he has been treated with D-penicillamine, large fluid intake and conversion of urine pH.

Purpose: To report a case of accidental swallowing of nasal packing gauze during silicone tube intubation under local anesthesia.Case summary: A 58-year-old male patient underwent silicone tube intubation for partial nasolacrimal duct obstruction on the right side. In preparing for surgery, six cottonoids soaked were packed in righ nasal cavity, to facilitate anesthesia and prevent bleeding. Strings detectable by X-ray were attached at the cottonoids and cut 5 cm from the nostrils. After surgical hand scrubbing, the strings were not present. One cottonoid was found in the nasal cavity, but five cottonoids could not be detected by endonasal endoscopic exploration. The patient said he swallowed “something like sputum”. He did not notice any discomfort and the surgery was performed as scheduled. Abdominal X-ray performed immediately after surgery showed the presence of the five strings in the stomach. The strings were not seen on X-ray conducted 4 days later. The patient defecated normal stools three times and did not notice any discomfort over the course of 4 days. Conclusions Surgeons need to be aware of the possibility of accidental swallowing of nasal packing gauze during nasolacrimal duct surgery. Use of gauze detectable by X-ray is helpful to determine its location.

PURPOSE: To evaluate the clinical and radiological outcomes, and the complications of unicompartmental knee arthroplasty (UKA) using a fixed bearing prosthesis after 5-year follow-up. MATERIALS AND METHODS: Twenty-six knees (25 patients) that underwent fixed bearing UKA between May 2003 and August 2011 were included. The subjects were 3 males (3 knees) and 22 females (23 knees), and the average age was 63.5 years. The preoperative diagnosis was osteoarthritis (23 knees) and osteonecrosis (3 knees). The mean follow-up duration was 67 months (from 60 to 149 months). The clinical evaluation included pre- and postoperative American knee society knee and function score, and range of motion. The radiology evaluation included standing antero-posterior, lateral view, and fluoroscopic film to analyze the postoperative alignment and osteolysis. RESULTS: The mean American Knee Society knee score and function score were improved from 42.0 and 57.5 to 87.9 and 85.0, respectively (p < 0.001). The mean preoperative and postoperative range of motion was 132.9° and 132.5°, respectively. The mean femorotibial angle were varus 0.5° preoperatively and valgus 2.2° postoperatively. A radiolucent line was observed in 2 knees; one knee had a stable implant, while in the other knee, patellofemoral arthritis was identified during UKA. Diffuse pain of the knee joint with tenderness of the medial joint line was identified at the follow-up, so conversion to total knee arthroplasty was recommended. No other complications, such as osteolysis, infections, postoperative stiffness, and dislocation, were encountered. CONCLUSION: The midterm results of fixed bearing UKA were clinically and radiologically satisfactory.

PURPOSE: This study aimed to verify the safety of low-dose topiramate on language development in pediatric patients with migraine. METHODS: Thirty newly diagnosed pediatric patients with migraine who needed topiramate were enrolled and assessed twice with standard language tests, including the Test of Language Problem Solving Abilities (TOPs), Receptive and Expressive Vocabulary Test, Urimal Test of Articulation and Phonology, and computerized speech laboratory analysis. Data were collected before treatment, and topiramate as monotherapy was sustained for at least 3 months. The mean follow-up period was 4.3±2.7 months. The mean topiramate dosage was 0.9 mg/kg/day. RESULTS: The patient's mean age was 144.1±42.3 months (male-to-female ratio, 9:21). The values of all the language parameters of the TOPs were not changed significantly after the topiramate treatment as follows: Determine cause, from 15.0±4.4 to 15.4±4.8 (P>0.05); making inference, from 17.6±5.6 to 17.5±6.6 (P>0.05); predicting, from 11.5±4.5 to 12.3±4.0 (P>0.05); and total TOPs score, from 44.1± 13.4 to 45.3±13.6 (P>0.05). The total mean length of utterance in words during the test decreased from 44.1±13.4 to 45.3±13.6 (P<0.05). The Receptive and Expressive Vocabulary Test results decreased from 97.7±22.1 to 96.3±19.9 months, and from 81.8±23.4 to 82.3±25.4 months, respectively (P>0.05). In the articulation and phonology validation in both groups, speech pitch and energy were not significant, and all the vowel test results showed no other significant values. CONCLUSION: No significant difference was found in the language-speaking ability between the patients; however, the number of vocabularies used decreased. Therefore, topiramate should be used cautiously for children with migraine.

Purpose: We report an atypical case of ischemic oculomotor palsy occurring sequentially in both eyes and then improving, followed by a new abducens palsy in a diabetic patient with poor blood sugar control.Case summary: A 51-year-old woman presented with diplopia, dizziness, and pain in the right eye and was diagnosed with oculomotor palsy in the right eye. Magnetic resonance imaging of her brain was normal but glycated hemoglobin concentration was 13.4%. After 2 months, the third nerve palsy in the right eye had recovered completely but a new third nerve palsy occurred in the left eye. 1 month later, the symptoms had improved, and the patient did not return to our clinic until 18 months later, when she returned with new diplopia. This time, she was diagnosed with a sixth nerve palsy in the left eye and was observed while controlling her blood sugar. She recovered after 4 months. Conclusions Generally, cranial nerve palsies occur unilaterally in situations that can cause ischemia, such as diabetes, high blood pressure, and hyperlipidemia. Rarely, they occur bilaterally, or two or more cranial nerve palsies occur simultaneously. However, it is very rare that cranial nerve palsy occurs sequentially in both eyes under the same systemic blood sugar control. Diabetic patients with poor blood sugar control require long-term monitoring, considering the possibility of symptoms developing in both eyes with a time lag or other forms of ischemic cranial nerve palsy.

Purpose: This study aimed to project cancer incidence and mortality for 2025 to estimate Korea’s current cancer burden. Materials and Methods: Cancer incidence data from 1999 to 2022 were obtained from the Korea National Cancer Incidence Database, while cancer mortality data from 1993 to 2023 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against their respective years and then by multiplying the projected age-specific rates by the anticipated age-specific population for 2025. A joinpoint regression model was applied to identify significant changes in trends, using only the most recent trend data for predictions. Results: A total of 304,754 new cancer cases and 84,019 cancer deaths are expected in Korea in 2025. The most commonly diagnosed cancer is projected to be thyroid cancer, followed by the colorectal, lung, breast, prostate and stomach cancers. These six cancers are expected to account for 63.8% of the total cancer burden. Lung cancer is expected to be the leading cause of cancer-related deaths, followed by liver, colorectal, pancreatic, stomach, and gallbladder cancers, together comprising 66.6% of total cancer deaths. Conclusion The increasing incidence of female breast cancer and the rise in prostate and pancreatic cancers are expected to continue. As aging accelerates, cancer commonly found in older adults are projected to rise significantly.

Purpose: The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2022, with international comparisons. Materials and Methods: Cancer incidence, survival, and prevalence rates were calculated using the Korea National Cancer Incidence Database (1999-2022), with survival follow-up until December 31, 2023. Mortality data obtained from Statistics Korea, while international comparisons were based on GLOBOCAN data. Results: In 2022, 282,047 newly diagnosed cancer cases (age-standardized rate [ASR], 287.0 per 100,000) and 83,378 deaths from cancer (ASR, 65.7 per 100,000) were reported. The proportion of localized-stage cancers increased from 45.6% in 2005 to 50.9% in 2022. Stomach, colorectal, and breast cancer showed increased localized-stage diagnoses by 18.1, 18.5, and 9.9 percentage points, respectively. Compared to 2001-2005, the 5-year relative survival (2018-2022) increased by 20.4 percentage points for stomach cancer, 7.6 for colorectal cancer, and 5.6 for breast cancer. Korea had the lowest cancer mortality among countries with similar incidence rates and the lowest mortality-to-incidence (M/I) ratios for these cancers. The 5-year relative survival (2018-2022) was 72.9%, contributing to over 2.59 million prevalent cases in 2022. Conclusion Since the launch of the National Cancer Screening Program in 2002, early detection has improved, increasing the diagnosis of localized-stage cancers and survival rates. Korea recorded the lowest M/I ratio among major comparison countries, demonstrating the effectiveness of its National Cancer Control Program.
