[Following staging procedures, differentiated thyroid cancers i. e. papillary and follicular carcinomas, are surgically treated with intra- or extracapsular total thyroidectomy (depending on the anatomical extent of the disease) and selective lymphnode dissection. Postoperative complementary use of adjuvant external and systemic radiotherapy is the general practice. External irradiation decreases local/regional relapses in all cases. Radioiodine treatment decreases local/regional/ distant recurrences in cases of tumour cells capable of iodine uptake. Life-long thyroxine medication is required, with a TSH-suppressive dose for relapse prevention and hormone substitution. This treatment regimen, a careful follow-up, and adequate rescue therapy are the prerequisites of the generally excellent patient prognosis, i. e. a survival probability measurable in decades. In anaplastic carcinoma following extracapsular total thyroidectomy and lymph node dissection, external irradiation is always indicated. Chemotherapy has a benefical effect on survival. Hormone replacement therapy is necessary to substitute for the missing metabolic effect of the thyroid. This combined modality treatment leads to some improvement with regard to the prognosis of this poor-risk type of cancer. ]

["Programmed cell death" I read with great interest and attention Dr. Béla Szende's excellent communication on the biological and pathological significance of programmed cell death (apoptosis). Although the phenomenon of apoptosis (albeit under a different name) has been described for more than twenty years, its importance in the regulation of tissue homeostasis has only been recognized in the last few years. In 1991, for example, Jean Claude Ameisen and Andre Carpon of the Pasteur Institute in Lille put forward their hypothesis that apoptosis explains the qualitative and quantitative deficiency of helper T cells in HIV-infected patients.]

[Malnutrition is a chronic nutritional disorder resulting from insufficient intake of caloric energy and/or some fundamental nutrients. Since it is the most common public health problem in the world it has a great impact on pediatric morbidity and mortality. The etiology is extremely complex. When one considers the less severe symptoms and signs caused by vitamin-, mineral-, and trace element deficiencies, it is apparent that not only children living in underprivileged countries are affected. In the course of making the diagnosis an assess ment of the nutritional status should also be made, especially considering the above-mentioned marginal nutritional deficiencies. The most common manifestation of nutritional disorders is anemia, which is mostly caused by lack of iron, vitamin B12, folic acid and can be complicated by infections. Nutritional requirements can be affected by several drugs. That is why this medication-nutrition interaction has to be kept in mind during treatment. The interaction of malnutrition and infection is very important, primarily for three reasons: mechanisms by which infection complicates the metabolic and nutritional status of the host; importance of suboptimal nutritional status on susceptibility and severity of intercurrent infections; clinical and therapeutic implication of these interactions. ]

[Many thousands of hysterectomies are perfor med each year in women suffering from menorrhagia resistant to medical treatment but having, no demonstrable uterine abnormality. Hysteroscopy, the up to date diagnostic and therapeutic method can help to get advance in the diagnosis and therapy in these situations. In addition to permitting more precise diagnoses to be made, hysteroscopy allows the endometrium to be treated selectively under direct vision. The full thickness of the endometrium may be ablated using laser or resectoscope. The benefits of selective endometrial destruction versus hysterectomy are enormous. Patients undergoing endometrial ablation are frequently delighted with the short hospital stay, and the cost of this procedure is lower than the cost of hysterectomy. Many Müllerian fusion defects are amenable to hysteroscopic treatment. Patients with certain types of Müllerian defects undergoing hysteroscopic septotomy will enjoy as high a rate of reproductive success as those receiving more traditional procedures while avoiding the risks, the subsequent caesar sections, and the high cost. ]

[The authors performed serial examinations by a high resolution transvaginal transducer during the first trimester of pregnancy to show the most important stages of the early embryonal development. This is a preliminary study to a prospective, detailed screening programme in the first trimester of pregnancy. The earliest sign of pregnancy can be detected at the 29–31st days of menstrual age using vaginal transducer. During the 5th week the (secondary) yolk sac can be seen, which is an unambiguous evidence of an intrauterine pregnancy. The living embryo can be de monstrated on 36–38th days with the help of the pulsation of the embryonic heart tube. Certain embryonic structures appear in a defined order (developmental „calendar"). The physiologic midgutherniation can be observed during 7–11th weeks. Transvaginal sonography has gained popularity only recently due to technical advances. The main fields of use became gynaecology and early pregnancy, for there is no need to have a full bladder, for the lack of disturbing tissue layers. This method is essentially a combination of the bimanual gynaecological and the ultrasound examination. ]
Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.
Introduction - Coronavirus disease 2019 (COVID-19) is a respiratory infection that has rapidly become a global pandemic and vaccines against SARS-CoV-2 have been developed with great success. In this article, we would like to present a patient who developed Guillain-Barré syndrome (GBS), which is a serious complication after receiving the inactive SARS-CoV-2 vaccine (CoronaVac). Case report – A 76-year-old male patient presented to the emergency department with nine days of progressive limb weakness. Two weeks prior to admission, he received the second dose of CoronaVac vaccine. Motor examination revealed decreased extremity strength with 3/5 in the lower extremities versus 4/5 in the upper extremities. Deep tendon reflexes were absent in all four extremities. Nerve conduction studies showed predominantly reduced amplitude in both motor and sensory nerves, consistent with AMSAN (acute motor and sensory axonal neuropathy). Conclusion - Clinicians should be aware of the neurological complications or other side effects associated with COVID-19 vaccination so that early treatment can be an option.
Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.
After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.
Intracranial localization of Ewing’s sarcoma is considerably very rare. Herein, we present clinical and neuroimaging findings regarding a 4-year-old boy with intracranial Ewing’s sarcoma. He was born prematurely, suffered intraventricular haemorrhage, posthaemorrhagic hydrocephalus developed, and a ventriculoperitoneal shunt was inserted in the newborn period. The patient endured regular follow ups, no signs of shunt malfunction nor increased intracranial pressure were observed. The last neuroimaging examination was performed at 8 months of age. Upon reaching the age of 4 years, repeated vomiting and focal seizures began, and symptoms of increased intracranial pressure were detected. A brain MRI depicted a left frontoparietal space-occupying lesion infiltrating the superior sagittal sinus. The patient underwent a craniotomy resulting in the total excision of the tumour. The histological examination of the tissue revealed a small round blue cell tumour. The diagnosis was confirmed by the detection of EWSR1 gene translocation with FISH (fluorescent in situ hybridization). No additional metastases were detected during the staging examinations. The patient was treated in accordance to the EuroEwing 99 protocol. Today, ten years onward, the patient is tumour and seizure free and has a reasonably high quality of life.
