OBJECT: Risperidone, unlike other atypical antipsychotics, is thought to elevate prolactin levels. This paper examines the relationship of risperidone-induced hyperprolactinemia and the sexual dysfunctions of the patients in the real clinical practice. METHODS: Forty nine patients (male 22, female 27) with 6 month-over risperidone medication were assigned and serum prolactin was assayed in serum by radioimmunometric assay. In the distinction of sex, six adverse events possibly associated with increased prolactin levels were determined by interviewing the patients (poor erection, ejaculatory dysfunction, galactorrhea, decreased libido, orgasmic dysfunction and obesity in male;amenorrhea, vaginal dryness, galactorrhea, decreased libido, orgasmic dysfunction and obesity in female). RESULTS: In 49 patients, thirty six patients (male 15;56%, female 21;95%) showed hyperprolactinemia and twenty two patients (male 13;48%, female 8;36%) had sexual side-effects. Both risperidone dosage per day and duration were not correlated with prolactin levels and adverse events. There was no significant direct correlation between serum prolactin levels and sexual adverse events. CONCLUSION: The risperidone-associated increase in serum prolactin levels was not significantly directly correlated with the emergence of possible prolactin-related adverse events in the real clinical practice. However, our results suggest that risperidone-induced hyperprolactinemia may play a role in sexual dysfunction of female patients.

OBJECTIVES: To explore the naturalistic outcome of the schizophrenics, we evaluated key clinical outcome-drop-out rate and readmission rate among the 33 risperidone and 17 conventional antipsychotics(such as haloperidol, chlorpromazine, mesoridazine) treated patients who met DSM-IV diagnostic criteria for schizophrenia at psychiatric department of a university hospital. METHOD: Outcome data was extracted from the charts of 50-schizophrenic patients who were more than 2 years after initiation of treatment with risperidone and conventional anti-psychotics. RESULTS: During over the 2-year period, the drop-out rate of the conventional antipsychotics treated schizophrenics was significantly higher than that of risperidone treated patients. But no significant factors(such as age, education level, duration of illness) were found between these two differently treated groups. Among the risperidone treated patients, the percentage of readmission was 18.2% at 12 months and 45.5% at 24 months. CONCLUSIONS: Reduced drop-out and rehospitalization rate suggest that risperidone was better than conventional antipsychotics among schizophrenic patients in a university hospital. Our data may contribute essential functional outcome information to assist the clinician in long-term, comparative treatment evaluation in 'real' clinical practice.

Delusional parasitosis is characterized by the unshakeable belief of being infested with tiny (microscopic) insects. Patients spend much time trying to get rid of the bugs and suffer from these symptoms. Patients prefer to go to dermatologists because they have a strong conviction over the presence of a somatic disease and do not accept any psychiatric advice for their complaints. 'Folie a deux' or shared psychotic disorder (SPD) is a relatively rare syndrome, which has long attracted clinical attention. Delusional parasitosis is associated in 5-15% of SPD and can run within a family. We experienced delusional parasitosis as 'Folie a Deux' between a mother and her son and successfully treated them through early psychiatric intervention. We believe that attention should be drawn to DP with SPD.

OBJECTIVES: While most neurological models of schizophrenia have focused on cerebral functions, cerebellar abnormality, especially in cerebellar vermis has been repeatedly reported in schizophrenic patients from brain imaging and lesion studies. And cerebellar vermis has been implicated for adaptive control of saccadic eye movements, which has not been studied in schizophrenics to our knowledge. METHOD: We investigated saccadic adaptation using double-step paradigm in 5 patients with a DSM-IV diagnosis of schizophrenia and 5 age and sex-matched normal controls. Gaze and head movements were recorded with scleral search coil method in head-free condition. RESULTS: Time course of adaptation in schizophrenics was similar to that of normal control but it never reached to the complete level of adaptation seen in control, and accordingly gaze gain (gaze amplitude/target amplitude) was low even after 600 adaptive trials. Head contribution to gaze saccade was relatively low and time to peak head velocity was longer in schizophrenics. CONCLUSIONS: Our results suggested that schizophrenic patients used a different strategy of gaze control and some schizophrenics might have cerebellar abnormality. Variability across patients in adaptation parameters need to be further investigated in combination with cerebellar volumetry. This study was supported by "In-san Schizophrenia Research Grant" from the Research Institute of Korean Neuropsychiatric Association in 1997.

Synergistic integration of the Internet of Things (IoT), cloud computing, and big data technologies in healthcare have led to the notion of “smart health.” Smart health is an emerging concept that refers to the provision of healthcare services for prevention, diagnosis, treatment, and follow-up management at any time or any place by connecting information technologies and healthcare. As a significant breakthrough in smart healthcare development, IoT-enabled smart devices allow medical centers to carry out preventive care, diagnosis, and treatment more competently. This review focuses on recently developed patient health monitoring platforms based on IoT-enabled smart devices that can collect real-time patient data and transfer information for assessment by healthcare providers, including doctors, hospitals, and clinics, or for self-management. We aimed to summarize the available information about recently approved devices and state-of-the-art developments through a comprehensive, systematic literature review. In this review, we also discuss possible future directions for the integration of cloud computing and blockchain, which may offer unprecedented breakthroughs in on-demand medical services. The combination of IoT with real-time, remote patient monitoring empowers patients to assert more control over their care, thereby allowing them to actively monitor their particular health conditions.

Various vaccines have been developed to fight severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease 2019 pandemic.However, new variants of SARS-CoV-2 undermine the effort to fight SARS-CoV-2. Here, we produced S proteins harboring the receptor-binding domain (RBD) of the Omicron variant in plants. Plant-produced S proteins together with adjuvant CIA09A triggered strong immune responses in mice. Antibodies in serum inhibited interaction of recombinant human angiotensinconverting enzyme 2 with RBD of the Omicron variant, but not RBD of other variants. These results suggest that antibodies induced by RBD of the Omicron variant are highly specific for the Omicron RBD, but not for that of other variants.

The Korean Triage and Acuity Scale (KTAS) Committee under the Korean Society of Emergency Medicine developed a Korean pre-hospital emergency patient classification tool (Pre-hospital Korean Triage and Acuity Scale [Pre-KTAS]) under contract from the Ministry of Health and Welfare, Korea. The classification tool was developed separately for adults and children. The patient’ s emergency level is classified into five distinct levels and is the same as the KTAS classification system, which is a hospital-level emergency patient classification tool.

A 7-year-old spayed female English Cocker Spaniel dog presented with polyuria (PU), polydipsia (PD), intermittent vomiting, and weight loss. Physical examination revealed pale, tacky mucous membranes and severe emaciation. Hematological and biochemical examinations revealed moderate normocytic normochromic non-regenerative anemia and moderate azotemia. Abdominal ultrasonography demonstrated bilaterally small lumpy-bumpy kidneys with hyperechoic parenchyma as well as loss of renal corticomedullary junction. Based on clinical history and examinations, the dog was diagnosed with chronic kidney disease (CKD). The dog was treated with supportive care including fluid therapy, phosphate-binding agent, and histamine H2-receptor antagonist. Darbepoetin Alfa was administered to control renal secondary non-regenerative anemia. Prescribed diet with low-protein and low-phosphorus was fed to alleviate CKD signs. Further, dietary probiotics were supplemented. This case demonstrates that oral probiotic supplementation helped reduce blood urea-nitrogen (BUN) levels. This case indicates that dietary probiotics can be a potential alternative therapeutic agent for management of renal failure.

A 2-year-old intact female pomeranian dog presented dyspnea, labored breathing, cough, exercise intolerance, machinery heart murmur, and precordial thrill. A left-to-right patent ductus arteriosus (PDA) was diagnosed based on two-dimensional echocardiography, thoracic radiography, electrocardiography, and blood work. An angiography was performed to accurately evaluate the size and shape of the duct. An interventional approach for transcatheterial occlusion of the PDA was achieved using an Amplatz(R) Canine Duct Occluder (ACDO), which is a commercially available ductal occluding device. Due to the limited size of the dog's femoral artery, a device smaller [125% of minimal ductal diameter (MDD); recommended size: 150~200% of MDD] than recommended was mounted. After placement of the ACDO, precordial thrill and continuous heart murmur disappeared, and the patient was discharged the next day after stabilization with O2 supply. Upon follow up examination, dyspnea, labored breathing, cough, exercise intolerance, and cardiomegaly were improved with no complications after the procedure. The ACDO was well maintained in position. This case represents successful clinical application of the Amplatz(R) Canine Duct Occluder to achieve closure of a PDA using a slightly smaller device than the recommended size.
