PURPOSE: To analyze postoperative results of intermittent exotropia as a function of the difference in strabismic angles measured immediately and another time prior to the surgery. METHODS: We reviewed the clinical records of intermittent exotropia patients who received surgery and had differences greater than or equal to 10 prism diopters (PD) between the last preoperative measurement of strabismic angle and another previous measurement. After applying various exclusion criteria, 66 patients were entered into our study. At the last follow-up visit after surgery, we divided postoperative results into 3 categories: (1) poor; with greater than 10 PD of esotropia or angle of exodeviation of 20 PD or more (2) moderate; with 6-10 PD of esophoria/tropia or 10-19 PD exodeviation, or (3) good; with 1-5 PD of esophoria/tropia or an angle of exodeviation less than 10 PD, or orthophoria. RESULTS: Good results were higher in patients where the difference in strabismic angle was 10 PD or greater between the last measurement and any other earlier measurement. CONCLUSIONS: In cases of Intermittent exotropia where the last preoperative value of strabismic angle was greater than any previous preoperative measurement, surgical dosage based on the last preoperative measurement yielded better results.

There are very few case reports of the diagnosis and management of concurrent oral cavity and parapharyngeal space tumors. We present a case involving a 49-year-old female who presented with oral cavity squamous cell carcinoma confirmed by biopsy. Initial diagnostic workup revealed a concurrent parapharyngeal mass. Diagnostic studies and surgical therapy were tailored to account for both pathological entities. The patient was treated with a combination of surgery and adjuvant therapy. The surgical strategy was designed to address both lesions simultaneously. One year post-surgery, the patient had good response to therapy with no evidence of persistent or recurrent disease. This report discusses the outcome and treatment of a rare case of concurrent squamous cell carcinoma with a complicating parapharyngeal space tumor. It explores the diagnostic process, comprehensive workup, and the surgical management.

PURPOSE: Acute abdominal pain can be the result of many different pathophysiological processes. Among the many possible causes, acute mesenteric ischemia is a life threatening condition if the diagnosis is delayed. Generally, the mortality rate for other disease has gradually decreased; however, the mortality rate for acute mesenteric ischemia has not changed significantly and it continues to be 75% to 80% for acute mesenteric arterial embolism or thrombosis and 44% for acute mesenteric venous thrombosis. The aim of this study was to conduct an analysis of the clinical characteristics and mortality of the patients with acute mesenteric ischemia according to the etiology. METHOD: From 1989 to 2004, 43 patients were treated for acute mesenteric ischemia. Their mean age was 59 years, ranging from 24 to 81, and the male to female gender ratio was 24:19. We retrospectively analyzed their initial symptoms, the age and gender distribution, the treatment modalities and the mortality rates. RESULT: The causes of acute mesenteric ischemia were arterial embolism in 27 cases, arterial thrombosis including arterial dissection in 7 cases and venous thrombosis in 9 cases. Almost all of the patients complained of acute abdominal pain and abdominal tenderness. The overall mortality rate was 30.2% and the rates were 37.0% for mesenteric artery embolism, 42.9% for mesenteric artery thrombosis and 0% for mesenteric venous thrombosis. CONCLUSION: In this study, the causes of acute mesenteric ischemia were mesenteric artery embolism and thrombosis, including dissection and mesenteric venous thrombosis. The factors influencing the mortality were the cause of the acute mesenteric ischemia, the extent of involvement of the mesenteric vessels and the extent of bowel necrosis. Thus the most important things for the treatment of acute mesenteric ischemia are early diagnosis and proper treatment.

Alloimmune neonatal neutropenia (ANN) is due to maternal IgG neutrophil-specific antibodies that cross the placenta to sensitize fetal neutrophils and cause neutropenia in the neonate. Infection appears within a few days of life. Neutropenia worsens during the very first days of life and persists until 20-50 days in spite of the disappearance of detectable antibody in the infant's serum. We report a case of ANN in female neonate who was admitted on the 5th day of life due to poor oral intake. The diagnosis was made by indirect immunofluorescence with fluorescein-tagged antihuman globulin reagent. The patient was treated successfully with systematic intravenous antibiotics and highdose intravenous immunoglobulin (IVIG).

BACKGROUND/AIMS: We analyzed chronological changes in hemoglobin according to renal function changes over a 5-year follow-up period. METHODS: We enrolled 5,266 adults with a glomerular filtration rate (GFR) > or = 60 mL/min/1.73 m2 at an initial examination at a routine health check-up; a follow-up examination was conducted 5 years later. We categorized the subjects according to GFR ratio (groups 1, 2, and 3, defined as GFRratio > or = 1.00, 0.75 to 0.99, and < 0.75, respectively). RESULTS: The mean hemoglobin level in subjects with a GFR of 60 to 74 was higher than in those with a GFR of 75 to 89 or > or = 90 mL/min/1.73 m2 at the initial examination (all p < 0.001). Among females and males, the frequencies of increased hemoglobin were 46.8% and 40.6% in the GFRratio group 1, 52.4% and 46.1% in group 2, and 59.6% and 52.5% in group 3 over the 5-year period, respectively (all p < 0.001). With multiple logistic regression, group 3 showed 1.594-fold (95% confidence interval [CI], 1.127 to 2.225) and 1.353-fold (95% CI, 1.000 to 1.830) higher likelihoods of increased hemoglobin over the 5-year follow-up period in females and males, respectively. The estimated difference in hemoglobin level was highest in group 3 in both genders. These findings were more evident in subgroups without metabolic syndrome, diabetes mellitus, hypertension, or GFR less than 90 mL/min/1.73 m2. CONCLUSIONS: Among a population with GFR > or = 60 mL/min/1.73 m2, a mild decrease in GFR over a 5-year follow-up period was associated with an increase in hemoglobin levels.

Rhabdomyosarcoma is an aggressive malignant tumor rarely developing in the head and neck in adults. In the sinonasal region, rhabdomyosarcoma constitutes a clinically important group because of the difficulty of surgical resection and its generally poor prognosis. Inverted papilloma is a relative rare and benign sinonasal lesionconstituting 0.5% to 4% of all nasal tumors that has a known propensity for recurrence, local aggressiveness, and association with transformation to malignancy. Squamous cell carcinoma is the major malignancy that is associated with inverted papilloma. To our knowledge, this is the first case report of pleomorphic rhabdomyosarcoma accompanied with inverted papilloma, and we represent the case with a review of the related literatures.

BACKGROUND AND OBJECTIVES: Cigarette smoking and alcohol consumption are well known risk factors of laryngeal squamous cell carcinoma. Recently, attention has been focused on other risk factors such as human papillomavirus (HPV). The presence of HPV genome in the tumor has been reported to correlate with poor patient outcome. The integration of viral genome into the host DNA is believed to be helped by alcohol and cigarette smoking. This study attempted to evaluate the incidence of HPV in laryngeal cancer with regard to its stage and recurrence. MATERIALS AND METHODS: The authors examined the incidence of HPV in 61 cases of laryngeal cancers (34 supraglottic cancers, 26 glottic cancers, 1 subglottic cancer). The histologic type of tumor in all cases was squamous cell carcinoma. There were 8 patients in the stage 1, 26 patients in the stage 2, 14 patients in the stage 3 and stage 4. Recurrence of the disease during follow-up periods occurred in 12 patients (19.6%). Polymerase chain reaction (PCR) was performed using the consensus primers for HPV on the formalin-fixed, paraffin-embedded archival tissue. For cases with amplified products corresponding to the HPV genome, a dot blot hybridization was performed for typing the different HPV types. RESULTS: The HPV genome was identified in 5 cases (8%) of laryngeal squamous cell carcinomas by using PCR. In recurrent laryngeal cancer group, detection rate of HPV DNA was significantly greater than in the non-recurrent group (p<0.05). The dot blot hybridization showed only one case to be the HPV type 31. The other cases (4 cases) could not be typed using the dot blot hybridization. CONCLUSION: We can only say that the possible role of HPV in the carcinogenesis of larynx cancer is not yet resolved.

This case report concerns a young patient with an extremely rare combination of d-transposition of the great arteries (d-TGA) and anomalous origin of the right subclavian artery. In our patient, the right subclavian artery originated from the pulmonary artery, which is why he did not show reversed differential cyanosis. We conclude that the presence of an aortic arch anomaly should be considered in patients with d-TGA who do not present with reversed differential cyanosis. A further imaging work-up, including computed tomography or magnetic resonance imaging, might be helpful.

Background:
Low-density lipoprotein cholesterol is an important marker highly associated with cardiovascular disease. Since the direct measurement of it is inefficient in terms of cost and time, it is common to estimate through the Friedewald equation developed about 50 years ago. However, various limitations exist since the Friedewald equation was not designed for Koreans. This study proposes a new low-density lipoprotein cholesterol estimation equation for South Koreans using nationally approved statistical data.
Methods:
This study used data from the Korean National Health and Nutrition Examination Survey from 2009 to 2019. The 18,837 subjects were used to develop the equation for estimating low-density lipoprotein cholesterol. The subjects included individuals with low-density lipoprotein cholesterol levels directly measured among those with high-density lipoprotein cholesterol, triglycerides, and total cholesterol measured. We compared twelve equations developed in the previous studies and the newly proposed equation (model 1) developed in this study with the actual low-density lipoprotein cholesterol value in various ways.
Results:
The low-density lipoprotein cholesterol value estimated using the estimation formula and the actual low-density lipoprotein cholesterol value were compared using the root mean squared error. When the triglyceride level was less than 400 mg/dL, the root mean squared of the model 1 was 7.96, the lowest compared to other equations, and the model 2 was 7.82. The degree of misclassification was checked according to the NECP ATP III 6 categories. As a result, the misclassification rate of the model 1 was the lowest at 18.9%, and Weighted Kappa was the highest at 0.919 (0.003), which means it significantly reduced the underestimation rate shown in other existing estimation equations. Root mean square error was also compared according to the change in triglycerides level. As the triglycerides level increased, the root mean square error showed an increasing trend in all equations, but it was confirmed that the model 1 was the lowest compared to other equations.
Conclusion
The newly proposed low-density lipoprotein cholesterol estimation equation showed significantly improved performance compared to the 12 existing estimation equations. The use of representative samples and external verification is required for more sophisticated estimates in the future.

Objective:
Traumatic brain injury (TBI) is an important public health concern due to its high prevalence and mortality rate among young people. We investigated the clinical and social characteristics of patients who visited the emergency department due to TBI in whom brain computed tomography, was performed by age.
Methods:
We retrospectively analyzed 15,567 TBI patients who received a brain computed tomography evaluation at the emergency department of Korea University Hospital from March 2013 to February 2016. We divided patients into age groups by decade and analyzed factors such as sex, trauma mechanism, need for operation, hospitalization, and results of treatment.
Results:
The mean age was 42.0±22.8 years; the most common age group was the 50s (16.5%). Except for the age group over 70 years, males predominated. Under 9 years of age, public ambulance usage rate was lower than in other age groups. Regarding severity based on the Glasgow Coma Scale score, the proportion of mild cases was higher in those under 9 years of age (99.3%) and the proportion of severe cases was higher in those in their 20s (4.6%). The most common injury mechanism was blunt trauma, followed by car accidents. For those under 9 years of age, falls were more common than in other age groups. Only 20.5% of TBI patients were hospitalized and 11.9% were treated surgically, while 70.6% of patients were discharged home after treatment.
Conclusion
TBI may present with different characteristics depending on the age of the patients, thus prevention policies and clinical practice should be tailored to age.
