Journal of Clinical Neurology 2021;17(3):435-442
Background:
and Purpose To investigate the incidence and characteristics of neurological manifestations associated with coronavirus disease 2019 (COVID-19).
Methods:
We reviewed the medical records of the consecutive patients with COVID-19 who were admitted to the central infectious diseases hospital designated for the treatment of COVID-19 in South Korea between March 2020 and September 2020. Newly developed neurological manifestations associated with COVID-19 were investigated. The frequency and clinical features of the neurological manifestations were analyzed according to disease severity, which was classified according to World Health Organization interim guidance.
Results:
Of the 306 symptomatic patients, 186 (60.8%) developed at least one neurological manifestation during hospitalization. The most common neurological symptom was headache (n=102, 33.3%), followed by myalgia (n=96, 31.4%) and anosmia/ageusia (n=54, 17.6%). Acute stroke (all ischemic stroke) occurred in three (1.0%) patients, and new-onset seizures occurred in two (0.7%). Neurological manifestation was a presenting symptom of COVID-19 in 72 (23.5%) patients, and was the only symptom of COVID-19 in 12 (3.9%). Stroke, seizure, and impaired consciousness were significantly associated with severe to critical COVID-19, whereas headache and anosmia/ageusia were frequently found in patients with mild to moderate disease.
Conclusions
Neurological manifestations were commonly observed in patients with COVID-19. During the current pandemic, when patients present with new-onset neurological symptoms, COVID-19 may be considered as part of the differential diagnosis. Attention to severe neurological complications is needed, especially in patients with severe or critical COVID-19.

Seizure is an uncommon complication of coronavirus disease 2019 (COVID-19). The frequency and characteristics of new-onset seizures in hospitalized patients with COVID-19 were investigated. Of a total of 1,487 patients with confirmed COVID-19, six (0.4%) developed new-onset seizures. All six had severe or critical COVID-19 requiring intensive care and mechanical ventilation or high-flow oxygen therapy. Among COVID-19 patients admitted to the intensive care unit (n = 169), the incidence of new-onset seizures was 3.6%. Underlying structural lesions (acute infarction and remote hemorrhage), hypoxia, sepsis, and metabolic derangements were associated with the development of seizures. Of the six patients, three patients died, and, at the time of discharge, one patient had a severe disability, while the remaining two were well recovered.

PURPOSE: Cryoablation has been used successfully for the local treatment of renal cell carcinoma. Besides local destruction, Cryoablation has an immunogenic nature. In this study, we evaluated the anti-tumor immune response induced by cryoablation in renal cell carcinoma murine model. MATERIALS AND METHODS: Renal cell carcinoma was produced in BALB/c mice by the subcutaneous inoculation of Renca cells in the thigh. After 7 days, the tumors were removed using liquid nitrogen in cryoablation group and bipolar electrocoagulation in electrocautery group. For twelve days after re-inoculation of Renca cells at contralateral thigh, tumor volumes were measured daily to assess the effect against the growth of tumor. The immunocyte levels (T4, T8, B and NK cell) were determined to evaluate immune activity by FACS (Fluorescence activated cell sorter) analysis. The effect of cryoablation to induce apoptosis of tumor was evaluated by TUNEL (Terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-digoxigenin nick end-labeling) assay. RESULTS: The tumor volume of cryoablation group was significantly smaller than that of electrocautery group and control (p<0.05). Comparing with control, T cell level was significantly increased after cryoablation (p<0.05), but no group had a significant difference in the levels of B cell and NK cell by FACS analysis. The apoptosis index % of cryoablation group was significantly increased than that of control group (p<0.05) by TUNEL. CONCLUSIONS: Cryoablation could result in the inhibition of re-inoculated tumor growth and induce T cell mediated immune response. The active immune response may be attributed to the apoptosis of tumor after cryoablation.

In 1, 345 patients suspected of having pancreatic or biliary tract disease, 23 patients were shown to have biliary ascariasis demonstrated by endseopic retrograded cholangiopancreatog raphy, at Kwang Ju Christian Hospital from Sep. 1976 to Aug. 1983. Authors report the clinical study and ERCP finding of 23 cases of biliary ascariasis. The result were as follows. 1) Out of 1,345 cases of ERCP, biliary ascariasis were 28 cases, The ascaris were found in CHD & IHD in 21 cases, and 2 casee were found in Ampulla of Vater. 2) There was no specifia age incidence and male to female ratio was 1: 1.9, 3) The disease was more prevalent in spring & summer, and more prevalent in rural area than urban area. 4) The chief eomplaints were RUQ and epigastric abdominal pain. The cases which were admitetted within 2weeks of onset were 16 cases. 5) Ascaris in biliary tract were removed by operation in 14 cases, and EST were performed in 5 cases. Two cases werere moved by DORMIA basket under the endoscopic direct visualization. 6) We report E.S.T. as a new therapeutic method of biliary ascariasis.

PURPOSE: We investigated the correlations of serum total testosterone (TT) levels with body composition and physical fitness parameters in patients with erectile dysfunction (ED) to know the best exercise for testosterone deficiency. MATERIALS AND METHODS: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly correlated with serum TT levels. RESULTS: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation with serum TT levels. CONCLUSIONS: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory fitness via aerobic exercise.

Previously, we demonstrated the changes of erectile tissues by intraperitoneal administration of BPA with toxic dose (cumulative dose of 900mg) in the rabbit. We performed this study to investigate the changes of erectile tissues by intracavernosal administration of BPA with low dose. New Zealand white rabbits were treated intracavernosally with 1 mg, 1 micro gram, 1 ng, and 1pg of BPA. Four weeks after administration of BPA, the contractions and relaxation of cavernosal tissue strips were significantly suppressed in the BPA-treated animals in a dose-dependent fashion compared with the control animals. Histologically, thickening of tunica albuginea by increased collagen fibers, subtunical deposition of fat, and decreased sinusoidal space by severe cavernosal smooth muscle hyperplasia with fibrosis were observed in the BPA treated animals. These results suggest that xenoestrogen BPA may affect the erectile function through evident histological changes of the penis in low dose.

A case of primary carcinoid tumor of the liver with striking central fibrous scar in a 61-year-old male is reported. Tumor cells contained electron dense secretory granules with an average diameter 150~200 nm which demonstrated positive immunohistochemical reaction for neuron-specific enolase, synaptophysin and chromogranin. The stellate central scar was observed in various hepatic tumors including focal nodular hyperplasia, fibrolamellar carcinoma, or sclerosing hepatocellular carcinoma, but have not been reported in carcinoid tumor.
