[Vaccination against Streptococcus pneumoniae will be mandatory for infants and children from 1 July 2014 in Hungary. Since the introduction of the conjugate vaccine against Pneumococcus, the distribution of Pneumococcus serotypes has changed significantly. Surveillance data from the National Centre for Epidemiology show that certain vaccine-type pneumococcal serotypes have almost disappeared owing to the immunization program, while other serotypes have emerged. Nowadays serotype 3 and the multiresistant 19A serotype are the most frequent causes oif invasive infections. A study analysing the nasal carriage of children attending kindergartens also confirmed the decline of vaccine- serotypes parallel to vaccination coverage and the simultaneous emergence of previously very types, such as 19A. The most recent study examining nasal carriage of children attending nursery (age < 3 years) showed that the 13-valent conjugate vaccine has efficiently decreased the carriage of serotypes 3 and 19A, verifying that the immunisation program should be continued using the vaccine providing the broadest coverage against Pneumococcus.]

[Pneumococcal meningitis in children - 9 1/2-year-experience at Szent László hospital, Budapest, Hungary ]

IVÁDY Balázs, LIPTAI Zoltán, ÚJHELYI Enikő, BALÁZS György

[Background and objective - No recent publications are available about pneumococcal meningitis in Hungarian children. The aim of this study was to collect data of epidemiological, clinical and prognostic features of pneumococcal meningitis in children treated at Szent László Hospital, Budapest, Hungary. Methods - We conducted a retrospective review of medical charts and follow-up records of patients aged 1 to 18 years admitted to our Pediatric and Pediatric Intensive Care Units due to pneumococcal meningitis between 1st Jan 1998 and 30th Jun 2007. Results - 31 children with 34 cases of pneumococcal meningitis were admitted to our hospital in the study period. Two children developed recurrent illness. The mean age was 6 years, 26% were under 1 year of age. The mean duration of hospital stay was 21 days, 97% required intensive care. Frequent clinical symptoms were fever (100%), nuchal rigidity and vomiting (78%), altered mental status (71%), Kernig's and Brudzinski's signs (58%) and seizures (41%). Otitis media, sinusitis, mastoiditis were present in 44%, 58%, 41%, respectively. Subdural effusion, parenchymal cerebral lesion and sinus thrombosis were documented in 5, 3 and 2 cases, respectively. One third of the patients recieved ceftriaxon, two thirds were administered ceftriaxon and vancomycin. Adjunctive therapy with dexamethason was given to 91% of the children. 70% of patients required mechanical ventillation. 9 patients (25%) required endoscopic sinus surgery. In 13 cases (38%) mastoidectomy, in 5 children (15%) neurosurgery was performed. The case fatality rate was 23.5%. 8 (23.5%) patients had mild or moderate, 1 child (3%) developed severe neurological sequelae. Conclusion - Pneumococcal meningitis in children remains a source of substantial morbidity and mortality in childhood. The long hospital stay, the frequent need for intensive care and severe neurologic sequelae emphasize the importance of early diagnosis, early treatment and prevention with pneumococcal conjugate vaccines.]

[Bacterial meningitis is a life-threatening disease. The incidence of meningitis is about 2.6-6 cases per 100.000 adults per year in developed countries. The most common causative microorganisms are Sreptococcus pneumoniae and Neisseria meningitidis. A 33-year-old multigravida, at 24 week of gestation was admitted to the hospital because of ear pain, haedache, fever and confusion. Lumbal puncture was performed and cerebrospinal fluid analysis showed signs of bacterial meningitis. Latex agglutination test was positive for S. pneumoniae, Gram-positive diplococci have seen under microscope and later cultivation verified S. pneumoniae as the causative agent. After ceftriaxon, dexamethasone administration and treatment in intensive care unit, left side mastoidectomy was performed since cranial computed tomography showed acut exacerbation of chronic mastoiditis on the left side. After extubation, mobilisation and 14 days antibiotic treatment the patient, who had residual hearing loss on the left side, was discharged from the hospital. During the treatment the foetal parameters were normal. The patient at 39 week of gestation gave birth to a healthy infant. Forty-eight case reports have been published in this topic around the world until April, 2012. The most common causative agents were S. pneumoniae and Listeria monocytogenes. Because of the little amount of data, it is hard to appreciate the actual incidence and prognosis of this life-threatening illness both for mother and infant. As far as we know this is the first published case report of meningitis during pregnancy in Hungary. By this article we would like to draw attention to the importance of teamwork, of prevention of brain abscess formation and of the removal of the infection’s focus.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

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.
