Qualities of a good psychiatrist

Introduction: There is limited published work regarding the qualities of a good psychiatrist in Asia. With greater attention paid to psychiatry training in Singapore as a result of the Ministry of Health's National Mental Health Blueprint, there is a need to assess the qualities of a good psychiatrist to guide training. Methods: The present study consisted of two steps. First, a focus group of six senior psychiatrists was conducted to obtain a list of positive qualities of a psychiatrist. Second, an anonymous survey was sent to all psychiatry trainees and psychiatrists in Singapore to assess the relative importance of 40 qualities that were chosen from the list of qualities obtained from the focus group. Factor analysis was performed to elucidate the themes from the qualities and Friedman's χ² test was used to compare the ratings between themes. Results: The response rate was 48.7% (74 of 152). Analysis showed four themes among the qualities assessed: “personal values”, “professional”, “relationship”, “academic‐executive”. The highly ranked themes for a good psychiatrist were personal values and professional qualities. Lowly ranked themes were relationship and academic‐executive. Discussion: A good psychiatrist in Singapore is narrowly defined by personal values and professional qualities. Training should correctly be focused on clinical skills. There may be a place to give more emphasis to qualities within the themes of relationship and academic‐executive, which are related to the all‐round development of a psychiatrist.     

Citicoline Protects Against Cognitive Impairment in a Rat Model of Chronic Cerebral Hypoperfusion

Background and purpose

Cerebral white matter (WM) lesions are frequently observed in human cerebrovascular diseases, and are believed to be responsible for cognitive impairment. Various neuroprotective agents can suppress this type of WM or neuronal damage. In this study, we investigated whether citicoline, a drug used to treat acute ischemic stroke, can attenuate WM lesions and cognitive decline caused by chronic hypoperfusion in the rat.

Methods

Animals were divided into immediate- and delayed-treatment groups. Those in the immediate-treatment group received a sham operation, citicoline (500 mg/kg/day), or phosphate buffered saline (PBS) treatment. Citicoline or PBS was administered intraperitoneally for 21 days after occluding the bilateral common carotid arteries. Rats in the delayed-treatment group were intraperitoneally administered with either 500 mg/kg/day citicoline or PBS for 21 days beginning on the 8th day after the operation. From the 17th day of administration, the rats were placed in an eight-arm radial maze to examine their cognitive abilities. After completing the administration, tissues were isolated for Klüver-Barrera and the terminal deoxynucleotidyl transferase biotin-dUTP nick end labelling (TUNEL) staining.

Results

In the immediate-treatment group, cognitive functions were preserved in the citicoline-treated group, and WM damage and TUNEL-positive cells differed significantly between the citicoline- and PBS-treated animals. In the delayed-treatment group, there was no decrease in WM damage and TUNEL-positive cells, but cognitive improvement was evident for citicoline treatment relative to PBS treatment.

Conclusions

These results show that citicoline can prevent WM damage and aid cognitive improvement, even after a certain extent of disease progression. Citicoline might be useful in patients with acute ischemic stroke as well as in chronic stroke accompanied with cognitive impairment.     

Solitary pulmonary nodules: detection, characterization, and guidance for further diagnostic workup and treatment

OBJECTIVE: The purpose of our study is to improve radiologists' understanding of the clinical issues involved in making a diagnosis and to guide further diagnostic workup and treatment of solitary pulmonary nodules (SPNs). CONCLUSION: Information on the morphologic and hemodynamic characteristics of SPNs provided by dynamic helical CT, with high specificity and reasonably high accuracy, can be used for initial assessment. PET/CT is more sensitive at detecting malignancy than dynamic helical CT, and all malignant nodules may be potentially diagnosed as malignant by both techniques. Therefore, PET/CT may be selectively performed to characterize SPNs that show indeterminate results at dynamic helical CT.     

The crystal structure of acemetacin monohydrate (C21H18NO6Cl−H2O), A non-steroidal antiinflammatory agent

The molecular structure of acemetacin, 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid carboxymethyl ester, was determined by single crystal X-ray diffraction analysis. The compound was recrystallized from a mixture of acetone and water in triclinic, space group P1, with a=7.796(1), b=10.245(2), c=13.542(3) Å, α=97.35(1), β=96.34(1), ψ=107.06(1)°, and Z=2. The calculated density is 1.422; the observed value is 1.42 g/cm³. The structure was solved by the direct method and refined by full matrix least-squares procedure to the final R value of 0.037 for 2960 independent reflections. There are water molecules, which are thought to be co-crystallized during the evaporation procedure, with the ratio of one water per compound molecule in the crystal. The conformation of the compound is found to be very similar to that of indomethacin. The molecules are stabilized by three O?H…O type intermolecular hydrogen bonds between the oxygen of water molecule and those of the compound.     

Differences in Pathologic Features and Graft Outcomes of Rejection on Kidney Transplant

BackgroundRejection is still a barrier to long-term allograft survival, but there are not many reports of clinical outcomes according to rejection types. The purpose of this study was to investigate differences in pathologic features and graft outcomes of rejection on kidney transplant (KT).Materials and MethodsWe retrospectively analyzed 139 kidney transplant recipients diagnosed to rejection by allograft biopsy results between 2006 and 2018. We divided kidney transplant recipients into 3 groups as follows: T cell–mediated rejection (TCMR), antibody-mediated rejection, and mixed rejection. We investigated clinical characteristics, pathologic findings, death-censored graft survival rates, and patient survival rates among the 3 groups.ResultsMean follow-up duration was 113.5 (SD, 80.6) months. The mixed rejection group was the youngest significantly. There were no significant differences of the proportion of sex, KT type, KT number, number of HLA mismatches, induction immunosuppressant, and maintenance immunosuppressant among the 3 groups. In pathologic findings, microvascular inflammation and C4d were significantly different among the 3 groups. Death-censored graft survival of mixed rejection was the least. In multivariate analysis, recipient age, TCMR, and positive C4d were the risk factors associated with graft failure. However, patient survival rates showed no significant differences among the 3 groups.ConclusionsOur study showed that mixed rejection had poor prognosis in comparison with TCMR and antibody-mediated rejection groups, and TCMR and positive C4d were the most important risk factors for graft survival. Therefore, constant monitoring through allograft biopsy and early treatment for rejection are very important in post-transplant clinical outcomes.     

Patients Presenting with Advanced Human Immunodeficiency Virus Disease: Epidemiological Features by Age Group

We explored factors influencing presentation with advanced human immunodeficiency virus (HIV) disease by age group. Data were derived from a city-wide cross-sectional survey of 759 HIV-infected adults living in Seoul, Korea. The significance of each observed factor was assessed via multivariate logistic regression. Of subjects aged 20-34 years, lower educational level had a positive influence on presentation with advanced HIV disease (adjusted odds ratio [aOR], 2.43; 95% confidence interval [CI], 1.36-4.34); those recently diagnosed with HIV were more likely to be presented with advanced HIV disease (aOR, 3.17; 95% CI, 0.99-10.2). Of the subjects aged 35-49 years, those w ith advanced HIV disease were more likely to have been diagnosed during health check-ups (aOR, 2.91; 95% CI, 1.15-7.32) or via clinical manifestations (aOR, 3.61; 95% CI, 1.39-9.36). Of the subjects aged ≥ 50 years, presentation with advanced HIV disease was significantly more common in older subjects (aOR per increment of 5 years, 2.06; 95% CI, 1.32-3.23) and less common among individuals diagnosed with HIV in 2000-2006 (aOR, 0.18; 95% CI, 0.04-0.83). In conclusion, a lower educational level in younger subjects and more advanced age in older subjects positively influence the presentation of advanced HIV disease.     

Acute Pancreatitis Induced by Methimazole Treatment in a 51-Year-Old Korean Man: A Case Report

Methimazole (MMI)-induced acute pancreatitis is very rare but severe adverse reaction. A 51-yr-old male developed a high fever, chills, and abdominal pain, two weeks after commencement on MMI for the treatment of Graves'' disease. There was no evidence of agranulocytosis, and fever subsided soon after stopping MMI treatment. However, 5 hr after taking an additional dose of MMI, abdominal pain and fever developed again. His symptoms, biochemical, and imaging studies were compatible with acute pancreatitis. After withdrawal of MMI, he showed clinical improvement. This is the first case of MMI-induced acute pancreatitis in Korea. Clinicians should be aware of the rare but possible MMI-induced pancreatitis in patients complaining of fever and abdominal pain.

Prognostic Value of Volume-Based Metabolic Parameters Measured by 18F-FDG PET/CT of Pancreatic Neuroendocrine Tumors

Purpose

To date, the prognostic value of ¹⁸F-FDG PET/CT for patients with pancreatic neuroendocrine tumors (PNETs) has not been well characterized. We investigated the prognostic value of volumetric parameters using ¹⁸F-FDG PET/CT in this patient population.

Methods

We retrospectively reviewed 20 cases of pathologically proven PNET in patients who had undergone pre-therapeutic ¹⁸F-FDG PET/CT. PET parameters including maximum and average standardized uptake values (SUV_max, SUV_ave), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of the primary tumor were measured using a threshold SUV to determine the boundaries of the tumors. Univariate and multivariate survival analyses were performed with adjustments for PET parameters and other clinical values.

Results

The median clinical follow-up was 22.3 (range, 1.2–95.4) months. Cancer-related death occurred in 5 of 20 patients (25 %). Patients had clinical or pathological stages of I in seven patients, II in six patients, III in three patient, and IV in four patients. According to the WHO histological classification of subtypes, 3 patients exhibited well-differentiated PNETs, 13 patients had well-differentiated endocrine carcinomas, and 4 had poorly differentiatedendocrine carcinomas. Univariate analysis showed that tumor size (p = 0.028), AJCC stage (p = 0.009), T stage (p = 0.028), M stage (p = 0.029), treatment modality (p = 0.045), MTV (p = 0.003) and TLG (p = 0.027) were significant predictors of overall survival. On multivariate analysis, MTV (HR = 10.859, p = 0.031) was a significant independent predictor of overall survival along with the AJCC stage (HR = 11.556, p = 0.027).

Conclusion

In patients with PNETs, the MTV of the primary tumor as measured by ¹⁸F-FDG PET/CT along with the AJCC stage may be a significant independent prognostic factor for overall survival.     

Combination Nasolabial Transposition Flap and Island Pedicle Flap Following Mohs Surgery of Simultaneous Basal Cell Carcinomas Involving Both Nasal Alae

The nasal ala is a challenging area for surgical reconstruction, with thick sebaceous skin, the lack of an ample tissue reservoir, and an adjacent free margin. Numerous flaps have been reported for the repair of alae defects. A 71-year-old woman with simultaneous basal cell carcinomas involving both nasal alae was treated by Mohs micrographic surgery. The surgical defects measured 1.5×1.5 cm on the center of the right nasal ala and 1.0×1.0 cm on the left nasal ala, including the alar crease and rim. The right nasal ala was used as a nasolabial transposition flap and the left nasal ala was reconstructed by an island pedicle flap. The final shape and texture were satisfactory. The flaps survived and nasal symmetry was preserved. Combined nasolabial transposition and island pedicle flaps thus offer a superior esthetic and functional result owing to minimized tension. This may be a valuable reconstructive option in the repair of bilateral nasal alae defects.
