OBJECTIVES: Although there were many studies examining anxiety and depression in hospitalized medically-ill patients, there were few studies in examining anxiety and depression of non-psychiatric outpatients or comparative studies among the disease categories. Therefore, we wanted to explore 1) psychopathologies in the patients with chronic renal failure and those with chronic hepatitis, 2) differences of psychopathologies by severity, 3) differences of psychopathologies by the duration of illness, and 4) psychiatric consultation. This was the second series of the whole project. METHODS: From March to April 1999, 38 patients with chronic renal failure and 26 patients with chronic hepatitis who visited the medical outpatient department are included in the subject group and 116 persons who visited the health examination center in September 1999 are included in the control group. We reviewed the medical records of the patients and inquired what they thought the causes of their illness were. We evaluated the patients with State-trait anxiety inventory, Beck depression inventory, Symptom checklist-90-Revision. RESULTS: In state anxiety, 62.2% of the patients with chronic renal failure fell into the anxious group, which is somewhat greater than the 52.0% of those with chronic hepatitis. The rates in both subjects are significantly higher than that of the control group. 16.7% of the patients with chronic renal failure were depressed, which is somewhat greater than the 9.1% found in chronic hepatitis. The rates in both subjects showed no significant difference from that of the control group. When the state anxiety scores were compared during the duration of the illness, it was found to be relatively higher during the early phase of disease in both the chronic renal failure patients and the chronic hepatitis patients. In the depression, the scores were found to be relatively higher in the chronic renal failure patients when the duration of illness was between 1 to 5 years compared to other duration groups, while the patients of chronic hepatitis were found to be relatively constant. Most frequently, 36.2% of the patients with chronic renal failure and 24.3% of those with chronic hepatitis thought the cause of their illness to be 'psychological', but the rates of psychiatric consultation in both subjects are 5.7%, 7.7% respectively. CONCLUSIONS: Our results suggest that proper psychiatric interventions are not being conducted yet and more cooperative and integrative roles are required among psychiatrists and internists.

STUDY DESIGN: In vitro cell culture model. PURPOSE: We investigated the effect of diabetes mellitus (DM) on senescence of adult nucleus pulposus (NP) cells. OVERVIEW OF LITERATURE: DM is a major public health issue worldwide, especially adult-onset (type 2) DM. DM is also thought to be an important etiological factor in disc degeneration. Hyperglycemia is considered to be a major causative factor in the development of DM-associated diseases through senescence. However, little is known about the effects of DM on senescence in adult NP cells. METHODS: Adult NP cells were isolated from 24-week-old rats, cultured, and placed in either 10% fetal bovine serum (FBS, normal control) and 10% FBS plus two different high glucose concentrations (0.1 M or 0.2 M; experimental conditions) for 1 or 3 days. We identified and quantified the occurrence of senescence in adult rat NP cells using senescence-associated-beta-galactosidase (SA-beta-Gal) staining. We also investigated the expression of proteins related to the replicative senescence (p53-p21-pRB) and stress-induced premature senescence (p16-pRB) pathways. RESULTS: The mean SA-beta-Gal-positive percentage was increased in adult rat NP cells treated with high glucose in a dose- and time-dependent manner. Both high glucose levels increased the expression of p16 and pRB proteins in adult rat NP cells. However, the levels of p53 and p21 proteins were decreased in adult rat NP cells treated with both high glucose concentrations. CONCLUSIONS: The current study demonstrated that high glucose accelerated stress-induced senescence in adult rat NP cells in a dose- and time-dependent manner. Accelerated stress-induced senescence in adult NP cells could be an emerging risk factor for intervertebral disc degeneration in older patients with DM. These results suggest that strict blood glucose control is important in prevent or delaying intervertebral disc degeneration in older patients with DM.

Background:
Locked posterior fracture-dislocation of the shoulder (LPFDS) is a very rare injury that occurs predominantly in young patients following high-energy trauma. The long-term outcome of the treatment of this injury is often poor. This study sought to present the characteristics of injury, discuss the pathological anatomy, and to report the treatment outcomes of our case series.
Methods:
Between January 2012 and May 2018, a total of 234 patients who underwent surgical treatment for proximal humerus fractures were reviewed. Among them, six patients (mean age, 54.7 years; range, 35–76 years) with LPFDS were included in this study. Four patients were treated with open reduction and internal fixation (ORIF) with locking plates, one with hemiarthroplasty, and one with reverse total shoulder arthroplasty. Clinical results were evaluated by Constant, American Shoulder and Elbow Surgeons (ASES), and visual analog scale (VAS) scores and radiologic evaluation was conducted using follow-up radiographs.
Results:
The mean length of follow-up was 26.2 months (range, 12–54). The mean Constant, ASES, and VAS scores were 66.7, 65.5, and 2.2, respectively. Four patients who underwent ORIF achieved bony union, but avascular necrosis (AVN) of the humeral head was observed in two patients. No complications were observed in the patients who underwent arthroplasty surgery until final follow-up.
Conclusions
In the treatment of LPFDS, replacement arthroplasty can produce predictable results. The approach of ORIF may be considered as a first choice of treatment in young patients but is sometimes correlated with postoperative complications such as AVN and the functional outcomes may be unpredictable. Therefore, patients should undergo careful diagnosis and treatment of this type of injury.

Purpose:
The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2018.
Materials and Methods:
Incidence, survival, and prevalence rates of cancer were calculated using the Korea National Cancer Incidence Database, from 1999 to 2018, with survival follow-up until December 31, 2019. Deaths from cancer were assessed using causes-of-death data obtained from Statistics Korea. Crude and age-standardized rates (ASRs) for incidence, mortality, prevalence, and 5-year relative survival rates were calculated, and temporal trends for incidence and mortality rates were evaluated, with annual percentage changes.
Results:
In 2018, newly diagnosed cancer cases and deaths from cancer were reported as 243,837 (ASR, 270.4 per 100,000) and 79,153 (ASR, 73.3 per 100,000), respectively. The overall cancer incidence rates increased by 3.3% annually from 1999 to 2012, and decreased by 5.4% annually from 2012 to 2015, thereafter, followed by nonsignificant changes. Cancer mortality rates have been decreasing since 2002, with more rapid decline in recent years (annual decrease of 2.7% from 2007 to 2014; 3.7% from 2014 to 2018). The 5-year relative survival between 2014 and 2018 was 70.3%, which contributed to prevalent cases reaching over 2 million by the end of 2018.
Conclusion
Cancer statistics have improved significantly during the past two decades. However, there remain important challenges to be solved, such as controlling cancers with low survival rates. Cancer statistics can be used to discover blind spots in cancer control, and as evidence for developing and implementing future cancer control strategies.

Background:
A midshaft clavicle fracture is a common fracture that typically responds well to open reduction and internal fixation (ORIF). However, refracture can occur after implant removal (IR). This study aimed to analyze the rate of refracture and related factors after removal of the locking compression plate (LCP) for displaced midshaft clavicle fractures.
Methods:
We retrospectively reviewed the medical records of 201 patients who had undergone ORIF with LCP for midshaft clavicle fractures after IR after bony union from January 2011 to May 2018 at our institute. We evaluated basic demographic characteristics and radiographic parameters. All patients were treated with an LCP for primary fracture. The patients were divided into two groups: a refracture group that experienced a second fracture within 1 year after IR and a no-fracture group.
Results:
There were four cases (1.99%) of refracture; three were treated conservatively, while one was treated surgically. All patients achieved bony union. The average interval between refracture and IR was 64 days (range, 6–210 days). There was a significant difference in classification of fractures (AO Foundation/Orthopaedic Trauma Association [AO/OTA] classification) between the two groups. However, other patient demographics and radiographic measurements between refracture and IR, such as bone diameter, showed no significant difference between the two groups.
Conclusions
This study showed that one in 50 patients suffered from refracture after removal of the LCP. Thus, if patients desire IR, the surgeon should explain that there is a relatively higher possibility of refracture for cases with simple or segmental fractures than for other types of fracture.

Purpose:
The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2019.
Materials and Methods:
Incidence, survival, and prevalence rates of cancer were calculated using the Korea National Cancer Incidence Database, from 1999 to 2019, with survival follow-up until December 31, 2020. Deaths from cancer were assessed using causes-of-death data obtained from Statistics Korea.
Results:
In 2019, newly diagnosed cancer cases and deaths from cancer were reported as 254,718 (ASR, 275.4 per 100,000) and 81,203 (ASR, 72.2 per 100,000), respectively. For the first time, lung cancer (n=29,960) became the most frequent cancer in Korea, excluding thyroid cancer. The overall cancer incidence rates increased by 3.3% annually from 1999 to 2012, and decreased by 5.3% annually from 2012 to 2015, thereafter, followed by nonsignificant changes. The incidence of thyroid cancer increased again from 2016 (annual percentage change, 6.2%). Cancer mortality rates have been decreasing since 2002, with more rapid decline in recent years (annual decrease of 2.7% from 2002 to 2013; 3.3% from 2013 to 2019). The 5-year relative survival between 2015 and 2019 was 70.7%, which contributed to prevalent cases reaching over 2 million in 2019.
Conclusion
Cancer survival rates have improved over the past decades, but the number of newly diagnosed cancers is still increasing, with some cancers showing only marginal improvement in survival outcomes. As the number of cancer survivors increases, a comprehensive cancer control strategy should be implemented in line with the changing aspects of cancer statistics.
