Thyrotoxicosis (thyroid crisis) is a known cause of sudden death; however, only a few cases of death resulting from thyrotoxicosis have been reported. Histopathologic examination and postmortem thyroid function tests may be helpful in postmortem diagnosis, but their usefulness seems to be limited. We report three autopsy cases associated with thyrotoxicosis.

Coronavirus disease 2019 (COVID-19) vaccine-induced lymphadenopathy is a critical side effect that should be a concern to clinicians, patients, radiologists, and oncologists. Vaccine-induced lymphadenopathy causes a diagnostic dilemma, especially for breast radiologists who examine both axillary regions during breast ultrasound examinations. Appropriate imaging guidelines are needed to manage vaccine-induced lymphadenopathy for patients undergoing screening examinations or symptomatic patients, including cancer patients.Current Concepts: For patients with axillary lymphadenopathy in the setting of recent ipsilateral vaccination, clinical follow-up is recommended. In other scenarios, short-term follow-up axillary ultrasound examinations are recommended if the clinical concerns persist for more than 6 weeks after vaccination. To mitigate the diagnostic dilemma of vaccine-induced lymphadenopathy, patients should schedule screening imaging examinations before the first vaccination or at least six weeks following the second vaccination. For clinicians and radiologists, documenting the patients’ vaccination status is critical to decreasing unnecessary follow-up imaging, biopsies, and patient’s anxiety.Discussion and Conclusion: Our proposal can help reduce patient anxiety, provider burden, and costs of unnecessary evaluation of enlarged lymph nodes in the setting of recent COVID-19 vaccination. Further, it can avoid delays in vaccination and breast cancer screening during the COVID-19 pandemic.

Syphilis is a communicahble disease caused by the motile microaerophilic spirochete Treponema pallidum, which is only a netural pathogen for human. Prevalence of syphilis and other sexually transmitted diseases has traditioially fluctuated with changes in sccia, conditions and sexual behavior. Although sexual contact is the main route of transmission, T. pallidum may also be infected through direct contact with syphilitic lesions, blood transfusion, ingestion of menstrual blood or vaginal secretions, or trsnsplacental transemission. Fomites as the means of transfer is only hypothetical and account for very few, if any, infection. Prosectors, blood handlers and laboratory technicians are at risk for accidental inoculation with infected materials. In extremely unusual circumstances, infection by means of contact with a skin lesion and human bite have been reported. We report two cases of eyphilis following the abnormal imposition of hands, which caused unnecessary erosive trauma with fingernails,

The presence and distribution of pan-neuroendocrine markers such as neuron-specific enolase (NSE), chromogranin (CG), and synaptophysin (SYP) were investigated by immunohistochemistry in 15 cases of neuroblastic tumors, including four cases of neuroblastomas, six cases of ganglioneuroblastomas, and five cases of ganglioneuromas. Three cases of normal sympathetic ganglion were used for the normal control group. NSE was observed in all cases and both in ganglion cells and in neuropils. NSE was detected not only in the majority of the neuroblasts showing signs of differentiation, but also in some poorly differentiated neuroblasts. All cases of neuroblastic tumors were positive for CG, however, some variability of staining intensity and distribution patterns were noted. CG was found mainly in differentiated neuroblasts with enlarged cytoplasm and nuclei along the periphery of the perikaria, and was also found in the perinuclear regions of some undifferentiated cells. SYP was positive in 9 of 11 cases. In all of the 9 cases, SYP was detected in some differentiating neuroblasts and differentiated neuroblasts, as well as the mature ganglion cells. However, it has scarcely stained in dot or granular pattern. Two CG-negative tumors were also negative for SYP. Our data indicate that antibodies against NSE and CG are helpful as a diagnostic aid for neuroblastic tumors.

A case or right occipital lobe infarction initially detected by the visual field examination and confirmed with the computerized tomography is presented. Reduction of significance of visual field test for identification of intracranial lesion as, the initial diagnostic procedure after the orientation of computerized tomography is unlikely. An occipital lobe lesion developed following posterior cerebral artery thrombosis has introd uced silgnificant ophthalmic symptom, namey, visual field defect, diplopia, ipsilateral ocular pain, visual hallucination, photophobia, and Anton's syndrom, etc. A characteristic feature of left homonymous hemianopsia with macular sparing due to right posterior cerebral artery thromb osis is demonstrated.
