Purpose:
The coronavirus disease 2019 (COVID-19) pandemic disrupted the emergency medical care system worldwide. We analyzed the changes in the management of intracerebral hemorrhage (ICH) and compared the pre-COVID-19 and COVID-19 eras.
Materials and Methods:
From March to October of the COVID-19 era (2020), 83 consecutive patients with ICH were admitted to four comprehensive stroke centers. We retrospectively reviewed the data of patients and compared the treatment workflow metrics, treatment modalities, and clinical outcomes with the patients admitted during the same period of pre-COVID-19 era (2017–2019).
Results:
Three hundred thirty-eight patients (83 in COVID-19 era and 255 in pre-COVID-19 era) were included in this study. Symptom onset/detection-to-door time [COVID-19; 56.0 min (34.0–106.0), pre-COVID-19; 40.0 min (27.0–98.0), p=0.016] and median door to-intensive treatment time differed between the two groups [COVID-19; 349.0 min (177.0–560.0), pre-COVID-19; 184.0 min (134.0–271.0), p<0.001]. Hematoma expansion was detected more significantly in the COVID-19 era (39.8% vs. 22.1%, p=0.002). At 3-month follow-up, clinical outcomes of patients were worse in the COVID-19 era (Good modified Rankin Scale; 33.7% in COVID-19, 46.7% in pre-COVID-19, p=0.039).
Conclusion
During the COVID-19 era, delays in management of ICH was associated with hematoma expansion and worse outcomes.

This paper reports a rare case of a left sided thyroid hemiagenesis associated with papillary carcinoma. Thyroid hemiagenesis is a rare congenital anomaly resulted from failure of development on one of the thyroid lobes. Among several thyroid developmental anomalies, hemiagenesis is considered to be the rarest anomaly. In world literature to date, only about 310 cases have been reported. We present a case of thyroid hemiagenesis of the left lobe and isthmus in a 51-year-old female, along with radiological and operative findings. Our report can give the idea that the thyroid hemiagenesis may not influence the development of parathyroid glands.

OBJECTIVES: Voice and speech alternations that can occur after total thyroidectomy are usually due to recurrent or superior laryngeal nerve injury. These alterations may also be associated with other extralaryngeal factors, such as neck muscle dysfunction and scar contracture of the neck. We performed a prospective acoustic analysis on speech changes after surgery, in the absence of laryngeal nerve injury. METHODS: Patients aged 19 to 58 years undergoing total thyroidectomy, in the absence of laryngeal/pulmonary disease, previous neck surgery, or other malignant diseases, were recruited prospectively. For the running speech analysis, the speaking fundamental frequencies (SFo), range of SFo and speaking intensity were evaluated before surgery, 7 days, and 1 and 3 months after surgery. For consonant analysis, the acoustic distinctions of stop consonant, the voice onset time (VOT), vowel duration and closure duration were evaluated at the same periods. RESULTS: SFo and range of SFo were specifically diminished after surgery, while speaking intensities were not changed significantly after surgery. The thyroidectomized speakers displayed systematically varied VOT for the consonant production, which was phonetically representative. However, VOT after surgery could be longer in the strong aspirated and glottalized stops, but not in the lax stop than before surgery. The vowel and closure durations were not affected before and after surgery. CONCLUSION: Patients with thyroidectomy have some difficulty of pitch control and consonant articulation during speaking. VOT is also one of the meaningful acoustic parameters and provide a reference for comparing acoustic measures before and after thyroidectomy.

Situs inversus totalis (SIT) is a rare congenital condition in which the viscera are transposed as a mirror of normal physiologic arrangement. We describe a rare case of lingual thyroid associated with SIT. A 64-year-old female who was diagnosed with SIT, visited our clinic due to pharyngeal foreign body sensation. Physical examination revealed a 2.5x2.5x2.0 cm sized, pinkish, round mass in the base of the tongue. Computed tomography suggested the diagnosis of lingual thyroid. She has been on regular follow up with levothyroxine therapy. To our best knowledge, this is the first case of lingual thyroid (LT) associated with SIT. The literature is reviewed and clinical features about LT and SIT are presented.

BACKGROUND: The Korean Laboratory Accreditation Program (KLAP) by the Korean Society of Laboratory Medicine (KSLM) was started in 1999. We summarized history and achievement of KLAP for the last 8 yr. METHODS: We analyzed 8 yr data (1999-2006) of historical events, trends of participating laboratories, and scores according to the impact of the question to the outcome of the tests. Inspection check lists are for 'laboratory management', 'clinical chemistry', 'diagnostic hematology', 'clinical microbiology', 'diagnostic immunology', 'transfusion medicine', 'cytogenetics', 'molecular genetics', 'histocompatibility', 'flow cytometry', and 'comprehensive laboratory test verification report'. The laboratories with score 90 or higher got 2-yr certificate and laboratories with score between 60 and 89 got 1-yr certificate. The laboratories with score below 60 failed accreditation. RESULTS: The number of accredited laboratories was 2.4 times higher in 2006 (n=227) than in 1999 (n=96). Inspection check lists have been revised 5 times till 2006. The average accreditation rate was 99.6% during these periods and the 2-yr accreditation rate was 32.4% in 2000, 45.6% in 2001, 53.3% in 2002, 47.3% in 2003, 68.5% in 2004, 37.7% in 2005, and 47.7% in 2006. Number of participants in inspector training workshops increased from 89 in 2000 to 766 in 2006. CONCLUSIONS: The KLAP has been in place successfully and stabilized over the past 8 yr. It seemed to enhance the laboratory quality. Efforts for improvement of quality control and inspector training workshops appeared to be in the main contributing factors.

PURPOSE: The optimal interval at which to repeat prostate-specific antigen (PSA) measurement is controversial. We evaluated the probability of the serum PSA value increasing above specific cutoff values (4.0 ng/ml, 3.0 ng/ml, and 2.5 ng/ml) on annual follow-up visits in men with a lower baseline PSA than each cutoff value. MATERIALS AND METHODS: Between 2002 and 2006, a total of 14,459 men aged 40 to 79 years who underwent serum PSA determinations at least twice during health examinations at 11 medical centers were enrolled in this study. To reduce probable bias, we excluded men with pyuria, those with a baseline or follow-up PSA level of 10.0 ng/ml or more, and those with a history of medication with 5 alpha-reductase inhibitors. Serum PSA underwent logarithmic conversion to work out the normal distribution. The cumulative rate of freedom from increase in PSA above 4.0 ng/ml, 3.0 ng/ml, and 2.5 ng/ml was estimated with the Kaplan-Meier method according to baseline PSA range and age. The significance level was 1%. RESULTS: The rate of increase in PSA was lower in men who had a baseline PSA value in the low range and whose age was in the 40s or 50s. However, the cumulative rate of freedom from increase in PSA decreased as the PSA cutoff value was lowered. The optimal screening interval for men in their 40s and 50s whose baseline serum PSA level was 1.0 ng/ml or lower was 3 years when the significance level for PSA rising above 4.0 ng/ml was 1%. It was 2 years and 1 year, respectively, when the cutoff value was lowered to 3.0 ng/ml or 2.5 ng/ml. An annual PSA screening interval was recommended in men older than their 60s. CONCLUSIONS: The PSA test interval should be individualized according to baseline PSA, age, and PSA cutoff value.

PURPOSE: The aim of this study is to determine whether a difference in the amount of bone graft material is needed between edentulous patients and dentulous patients and to calculate the amount of augmentation for a sinus lift procedure. METHODS: 19 patients (20 sinuses) were included to measure maxillary sinus volume. Facial CT scanning was performed using MX 8000 IDT CT devices (Philips, USA). And it was used for IDLvm (The IDL Virtual Machine) 6.0, CT Volume Analyzer Ver 2.3 program to measure maxillary sinus volumes RESULTS: At edentulous patients, volumes (mean+/-SD) of the inferior portion of the sinuses were 0.56+/-0.13 cm3 (5mm height), 2.35+/-0.57 cm3 (10mm height), 4.85+/-1.10 cm3 (15mm height). At dentulous patients, volumes (mean+/-SD) of the inferior portion of the sinuses were 0.41+/-0.18 cm3 (5mm height), 1.76+/-0.42 cm3 (10mm height), 3.80+/-0.84 cm3 (15mm height). A significant correlation was found between augmentation height (5mm, 10mm, 15mm) and the calculated sinus volume. (p=0.027, p=0.018, p=0.044) CONCLUSIONS: A significant correlation was found between augmentation height (5mm, 10mm, 15mm) and the calculated sinus volume. Detailed preoperative knowledge of sinus lift augmentation volume is helpful in determining the appropriate amount of the bone graft material.

Femoral head and neck fractures during the course of avascular necrosis are rare with only few reports in the English literature. Moreover, there are very few reports on an analysis of the patterns of these fractures. Four cases of femoral head fracture caused by minor trauma, which were quite different from the crescent fractures during the course of avascular necrosis were analyzed in regard to the underlying disease, causes, sites, types, directions, pattern of fractures and the injury mechanism of the fractures. The results are reported with special regard to the pattern of the stress fracture of the femoral head and neck during the course of avascular necrosis.

BACKGROUND: Increased WBC counts have been associated with different components of metabolic syndrome (MS), accompanied by clustering of a number of risk factors for CHD. Because most individuals have one or more of the risk factors for CHD or a cluster of MS symptoms, it may not be appropriate to look only at isolated components. Therefore, the aim of the present study was to examine the association of WBC counts with clustered features of MS in Korean adults. METHODS: The subject of this study included 593 adults (males 344, females 249) aged 20 years or older. Among the subjects, we excluded those who did not have records of physical parameters and blood test results and those who did not complete the questionnaire. We also excluded acutely ill patients. Logistic regression analyses were used to evaluate the association between WBC counts and features of the MS, with an adjustment for age, smoking and alcohol consumption. RESULTS: The relative risks for obesity, hypertension, hypercholesterolemia, low HDL cholesterol levels, hypertriglyceridemia, high fasting plasma glucose levels and hyperuricemia compared with WBC counts <5.2 x 10(3) cells/microliter, increased as WBC counts increased. The relative risks for the presence of > or =1, > or = 2, > or = 3, > or = 4 features of the MS also increased as WBC counts increased. CONCLUSION: An increased, albeit normal, WBC counts associates with the cluster of MS of the so-called "insulin resistance syndrome" and suggest that an increased WBC counts may be yet another feature of this syndrome.
