Prevalence of internet gaming disorder among medical students at medical college in Jamnagar, Gujarat

Background: Smartphone usage became drastically increased in the past two decades. Spending abnormally more time playing games can lead to development of internet gaming disorder (IGD) which leads to negative impact on health and lifestyle. Aim and Objectives: The aim of this study was to find out the prevalence of IGD and smartphone usage patterns in medical students. Materials and Methods: The study was held in M. P. Shah Government Medical College in Jamnagar. Total 206 1st year medical students were included for this study. Pre-validated self-made questionnaire and pre-structured IGD-20 questionnaire were used in this study. Results: The prevalence of IGD in medical students is 1.46%. In male population, the prevalence of IGD was higher (1.6%) compared to female population (1.23%). Conclusion: IGD can be a great disaster if remain unnoticed. It can change one’s lifestyle gradually. Preventive measures such as parental locking system and strong rules for mobile phone use in university hours should be implied.

IgD multiple myeloma: report of 1 case and review of literature / 白血病·淋巴瘤

Objective:To investigate the clinical features of IgD multiple myeloma (MM) and the effect and prognosis of daratumumab-based combination therapy.Methods:The clinicopathological data of a IgD MM patient with disease progression and extramedullary infiltration treated with daratumumab in the Affiliated Hospital of Qingdao University in December 2019 were retrospectively analyzed.Results:The 74-year-old woman was diagnosed as IgD MM by bone marrow aspiration and immunofixation electrophoresis. The patient was given VD (bortezomib, dexamethasone), RD (lenalidomide, dexamethasone) and ID (ixazomib, dexamethasone) regimens. In June 2020, the patient developed multiple subcutaneous nodules, and she was assessed as progressive disease with extensive extramedullary infiltration. After treated with daratumumab-PAD (liposomal doxorubicin, bortezomib, dexamethasone) regimen, the patient's subcutaneous nodules were significantly reduced and partially disappeared, and the general condition was significantly improved. But the patient was in a cachexia state and finally died of the irregular treatment and disease progression.Conclusions:IgD MM has a low incidence and a short survival period, and there is no uniform standard treatment. The early application of daratumumab combined with proteasome inhibitors, immunomodulators, cytotoxic drugs and hematopoietic stem cell transplantation may improve the overall survival of patients.

Factors Correlated With Internet Gaming Disorder Among Malaysian University Students

@#Introduction: Internet gaming disorder (IGD) has recently been incorporated into the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) as a disorder for future research. The primary objectives of the present study are to describe the level of IGD and to examine its correlations with sociodemographic factors and psychological comorbidities among undergraduate students in a Malaysian university. Methods: A total of 411 undergraduate students completed an online questionnaire. They were selected from a random sample of participating university faculties. The online questionnaire contained the Internet Gaming Disorder Scale-Short-Form and the Depression, Anxiety, Stress Scale. Results: The presents study reported that 52.8% of the participants had high IGH. Using hierarchical multiple regression, age (β = -0.09, p < 0.05), gender (β = -0.40, p < 0.001) and stress (β = 0.23, p < 0.05) were statistically significant predictors of IGD. Academic performance, depression and anxiety did not emerge as significant predictors. Conclusion: These findings highlight the risk factors (in particular, stress) of IGD. Further studies on interventions, particular that of preventative strategies, will be needed to combat this emerging public health problem.

Mevalonate Kinase Deficiency as Cause of Periodic Fever in Two Siblings

Mevalonate kinase deficiency (MKD) is a rare autosomalrecessive autoinflammatory disease caused by mutations inMVK. We report two siblings with MKD, presenting withrecurrent febrile illnesses, detected to have compoundheterozygous variants in MVK. MKD mimics common pediatricconditions and should be considered as a differential diagnosis.

Multi-components compatibility theory of Chinese materia medica and IGD 13C-NMR coupling fingerprint / 中草药

Multi-components compatibility theory of Chinese materia medica (CMM) has been more and more mature and perfect, because of the efforts of many scientific and technological workers for nearly 20 years. Omics, compatibility, and fingerprint are the three key words of the multi-components compatibility theory. Namely in multi-components compatibility theory, modern "omics" and traditional "compatibility" are closely combined through "fingerprint". The modernization of CMM has developed to such a stage that the fingerprint (especially IGD 13C-NMR coupling fingerprint) method could be used to study morden CMM under the guidance of multi-components compatibility theory.

The first report of myeloma with IgD κ and free κ in Indonesia.

IgD κ myeloma is a rare plasma cell neoplasm case and has never been reported before in Indonesia. In normal condition, IgD level in blood is very low, therefore increase of IgD level in myeloma could be missed by serum protein electrophoresis. A case of a 59 years old female with severe bone pain is reported. In radiology evaluation, there were thoracal compression fracture and thoracal foramen narrowing. For this patient, the myeloma diagnosis was based on WHO criteria, the stage IIIb was based on Durie and Salmon criteria, and bad prognosis with prognostic index stage III diagnosis was based on International Prognostic Index from International Myeloma Working Group, respectively. In serum protein electrophoresis we found a very small monoclonal spike and in immunofi xation there were monoclonal IgD κ and free light chain κ.

Myelomatous Pleural Effusion: A Case Series in a Single Institution and Literature Review / 대한진단검사의학회지

BACKGROUND: Myelomatous pleural effusion (MPE) is rare in myeloma patients. We present a consecutive series of patients with MPE in a single institution. METHODS: We retrospectively reviewed the medical records of 19 patients diagnosed with MPE between 1989 and 2008 at the Asan Medical Center. Diagnoses were confirmed by cytologic identification of malignant plasma cells in the pleural fluid. RESULTS: Our patients showed dominance of IgA (36.8%) and IgD (31.6%) subtypes. Of 734 myeloma patients, the incidence of MPE was remarkably high for the IgD myeloma subtype (16.7%), compared to the other subtypes (1.4% for IgG and 4.6% for IgA). At the time of diagnosis of MPE, elevated serum beta2-microglobulin, anemia, elevated serum lactate dehydrogenase, and elevated creatinine levels were found in 100%, 89.5%, 83.3%, and 57.9% of the patients, respectively. Approximately one-third (31.3%) of the patients had adenosine deaminase (ADA) activities in their pleural fluid exceeding the upper limit of the reported cutoff values for tuberculous pleural effusion (55.8 U/L). Chromosome 13 abnormality was seen in 77.8% of the tested patients. The median survival period from the development of MPE was 2.8 months. CONCLUSIONS: Patients with MPE have aggressive clinical and laboratory characteristics. The preponderance of IgD myeloma in MPE patients is a noteworthy finding because IgD myeloma is a rare subtype. Elevated ADA activity in the pleural fluid is also noteworthy, and may be helpful for detecting MPE. Physicians treating myeloma patients should monitor the development of MPE and consider the possibility of a worse clinical course.

A Case of Secondary Cutaneous Plasmacytoma, IgDlambda Type on Scalp / 대한피부과학회지

Cutaneous plasmacytoma (CP) is a localized collection of monoclonal plasma cells in the skin. The disease is divided into primary cutaneous plasmacytoma and secondary cutaneous plasmacytoma groups. Secondary cutaneous plasmacytoma, which is so rare as to occur in only 2% of myeloma cases, usually represents terminal expression of the primary diseases and is associated with increased tumor burden. CP can occur at any site of the skin, but we could find only 1 case in English literature related to scalp metastasis alone. Also serum and urine electrophoresis, tissue immunohistochemistry for IgD are not usually conducted in the laboratory. IgDlambda subtype seems to be another value to report. We report a case of secondary cutaneous plasmacytoma, IgDlambda type which developed on the scalp alone of a 41-year-old woman, with a review of related literatures.
