✓ Therapeutic results in 17 cases of alpha-fetoprotein (AFP)-secreting tumors of the central nervous system are reported. Twelve of the patients were male and five female. The patients' ages ranged from 5 years to 25 years (mean 13.6 years). The tumors originated in the pineal region in 10 cases, in the suprasellar region in four cases, and in both regions in one case; of the other two tumors, one originated in the basal ganglia and one in the sacrococcygeal region. Extraneural metastases or subarachnoid dissemination occurred in seven cases. Increased AFP titer in the serum or cerebrospinal fluid was verified in 13 cases. The patients were divided into two groups: those treated before (Group A) and those treated after (Group B) the introduction in 1980 of cisplatin as a chemotherapeutic agent. All seven Group A patients died, even after extensive therapy consisting of surgery, radiotherapy, and chemotherapy (ACNU or adriamycin) in some of the cases. The mean survival time following diagnosis for Group A was 23.7 months. Six of the 10 Group B patients died an average of 25.8 months after diagnosis; however, the other four were still alive and well an average of 25.3 months after diagnosis. The tumors responded well to chemotherapy consisting of cisplatin either alone or combined with bleomycin and vinblastine. The initial response rate to treatment in Group B was 100% and five cases had a complete remission, verified by computerized tomography or the serum AFP level. Once the tumor recurred, the response to cisplatin was markedly decreased. It is suggested that an effective therapy must still be sought for recurrent tumors.

✓ Two patients are reported who had intracerebral mass lesions composed of hemangioma and glial neoplasm. After excision, one recurred as an oligodendroglioma, and the remnant of the other remained static over a 5-year period. These lesions may represent a subgroup of cerebral hemangiomas that have the biological potential for future glial neoplastic growth. Reference is made to experimental work with polyoma virus which can induce cavernous hemangiomas in the central nervous system in mice, and which is a papovavirus. Other papovaviruses can induce ependymomas in hamsters.

Abstract Background Arsenic trioxide provides significant benefits in newly diagnosed and relapsed acute promyelocytic leukemia (APL) respectively. However, the high relapsed rate is still threatened the life of APL patients. Which regimen should be used to overcome or reduce the relapse in consolidated treatment is a key problem at present. We performed a pilot study about that. Objective To Compare the effectiveness and security of cocktail therapy with single arsenic trioxide therapy in APL consolidated treatment. Methods Sixty-Five APL patients, who once received arsenic trioxide treatment and obtained complete remission, were enrolled in this study. Patients were divided into two groups according to the different consolidated regimens. After reinforced treated with DA (daunomycin and cytarabine) or HOAP (harringtonine, vincristin, cytarabine and prednisone) for two course, Group A involved twenty cases received single arsenic trioxide consolidated, Group B included forty-five cases treated with the cocktail therapy, alternatively treated with arsenic trioxide, all trans-retinoic acid and chemotherapy (DA or HOAP). The relapse rates, the survival rates and the central nervous system infiltration rates in 3 years followed up were compared. Results The relapsed rate of Group A was 55%, which was higher than that of Group B(17.8%). The re-remission rate after the first relapse in Group A was 22%, which was lower than that of Group B(42.8%). The central nervous system infiltration rate of Group A was 28%, which was higher than that of Group B(6%). The average survival time of Group A was 10.5±4.2months, which was shorter than that of Group B (22.5±5.5 months). The three-year survival rate of Group A was 15%, which was less than that of Group B (65.8%). Conclusions Cocktail therapy —alternatively treated with arsenic trioxide, all trans-retinoic acid and chemotherapy will be the reasonable regimen for APL consolidated treatment. Which provided benefited on inhibiting relapse and central nervous system infiltration of APL.

✓ A neoadjuvant (preradiotherapy) chemotherapy regimen consisting of either cyclophosphamide alone (60 to 80 mg/kg) or a modified multidrug regimen (vinblastine, bleomycin, cyclophosphamide, and cisplatin) was administered to 15 newly diagnosed patients with histologically confirmed, fully staged, primary germ-cell tumors (GCT's) of the central nervous system (CNS). There were 11 patients with germinomas and four with non-germinoma malignant GCT's. There were six females and nine males, whose median age was 13 years (range 4 months to 24 years). Seven germinoma patients (64%) had disseminated disease. For the germinoma patients, the subsequent radiotherapy dose was modified based on the response to the neoadjuvant chemotherapy, and craniospinal radiotherapy was given only to those with disseminated CNS disease at diagnosis. Ten of the 11 germinoma patients had complete disappearance of all evaluable disease after two courses of chemotherapy (cyclophosphamide in eight and multidrug in three) and one had a partial response. The planned dose of radiotherapy to the primary tumor was reduced from 5500 to 3000 rads, and the craniospinal dose was lowered from 3600 to 2000 rads. Ten patients remain in continuous disease-free remission 20+ to 89+ months after diagnosis (median follow-up period 47 months). All four patients with non-germinoma GCT's received the multidrug regimen, and two of three patients with evaluable disease had a partial response. High-dose regional and craniospinal radiotherapy was administered thereafter, but only two patients remain in their first remission. Previously untreated germinoma is a highly chemosensitive disease and the neoadjuvant treatment strategy permits the identification of active chemotherapy regimens in newly diagnosed patients. Patients who have complete responses to neoadjuvant chemotherapy tolerate a significant radiotherapy dose reduction without compromising long-term survival, thereby allowing a reduction of some of the late effects of therapeutic radiation. Germinomas tend to disseminate early in the course of the disease and a pre-therapy staging evaluation permits individualized radiotherapy treatment planning.

Background: Brain tumors are the most common solid neoplasia and the main cause of death from malignancy in children. Germ cell tumors (GCT) of the central nervous system (CNS) are rare. In pediatrics, the main location is close to the pineal gland and germinomas are the most common intracranial GCTs. Objectives and Methods: To describe the case of a patient with a possible germinoma treated exclusively with radiotherapy. The case was studied and came from a referral hospital – João Pesssoa, PB. Results: Reports “impaired failure”, disorientation and headache. Computed tomography: Hydrocephalus and strong tumor suspicion in the pineal region. Alpha-fetoprotein (AFP) and beta-gonadotropin (betaHCG) measurements: Normal. Treatment can be based on radiotherapy or chemotherapy followed by radiotherapy. In this case, radiotherapy was performed at a dosage of 10 Gy, with control, after one month, by means of magnetic resonance imaging that revealed regression of the lesion. The treatment corroborated the hypothesis of a germinoma, which is extremely radiosensitive. However, the regression made it impossible to perform the anatomopathological exam for diagnostic conclusion. Conclusions: It can be seen, then, that primary CNG GCTs are part of a heterogeneous group of extremely rare lesions, with germinoma therapy still controversial. The case shows regression of a possible germinoma only with the use of radiotherapy.

Abstract PURPOSE R-MPV-A therapy has recently been reported to improve the outcomes of primary central nervous system lymphoma (PCNSL). Our patients have received R-MPV-A therapy since 2017 and elderly patients have only been treated with whole brain radiotherapy when they do not show a complete response after induction chemotherapy. We report the therapeutic outcomes and problems of elderly PCNSL patients treated with R-PMV-A. MATERIALS & METHODS Eight newly diagnosed PCNSL patients received R-MPV therapy from September 2017 to June 2019. We retrospectively reviewed the cycles of R-MPV therapy, radiotherapy, consolidation high-dose Ara-C (HD-Ara-C) therapy, and the G8 score (a geriatric assessment). RESULTS Patients were divided into three groups: Group A (71–75 years; n=2), Group B (76–80 years; n=4), and Group C (>81 years; n=2). All Group A patients finished 5 cycles of R-MPV therapy, showed a complete response, and underwent consolidation HD-Ara-C therapy. Two Group B patients showed a complete response on R-MPV therapy. One of the other patients showed a partial response after 3 cycles of R-MPV therapy, and a >3 kg reduction in body weight. The patient’s G8 score was 12 points. Whole brain radiotherapy (23.4 Gy) was administered followed by local radiotherapy (21.6 Gy). One patient showed a partial response after 7 cycles of R-MPV therapy and started radiotherapy. One Group C patient received radiotherapy after 3 cycles of R-MPV because of a new lesion. The other Group C patient showed acute renal damage after 3 cycles of R-MPV. CONCLUSION R-MPV-A therapy was relatively safe for our elderly PCNSL patients. Notably, patients >76 years of age sometimes had severe adverse effect with increased R-MPV cycles. A promising therapeutic strategy based on age and geriatric assessment is needed.

Abstract BACKGROUND Brain invasion has already been identified as an independent criterion of meningioma recurrence by Jääskaläinen’s in 1986. While it was only suggested that meningiomas harbouring brain invasion could be staged as grade II in the 2007 WHO Classification of Tumours of the Central Nervous System, brain invasion was clearly listed as a grade II atypical meningioma criterion for the first time in the 2016 version. Since 2007, brain invasion has been carefully screened during the histopathological characterisation of meningiomas in our centre thanks to specific training of the neuropathology department staff. Furthermore, neurosurgeons are asked to provide well-preserved and grossly orientable tumours borders whenever possible. The aim of the present study was to compare the characteristics of patients diagnosed with grade II meningiomas before and after this change of practices. MATERIAL AND METHODS We retrospectively reviewed the characteristics of 125 patients with grade II meningiomas diagnosed between 2011 and 2014 (group A) and compared them to those of 166 patients with grade II meningiomas diagnosed between 1998 and 2005 (group B). RESULTS Tumour location and socio-demographic parameters were comparable in group A and B with a median age of 62 years in both groups (p=0.18). There were more de novo meningiomas in group A (84% vs 68.7%, p=0.004). Brain invasion was found in 59% in group A and 9% in group B (p=0.00001) while median Ki67 labelling was of 8.4% in group A and 10.5% in group B (p=0.04). Consistently, tumour borders were irregular in 52% in group A and 29% in group B (p=0.0002). Progression free survival was similar in the two groups (65 vs 66 months, p=0.92) but grade progression was more frequently observed in group B (18.9% vs 0%, p=0.006). In group A, meningiomas that were classified as grade II exclusively based on brain infiltration (n=33, group A-bi) had a similar progression rate compared to meningiomas with other criteria of atypia (27% vs 25%, p=0.98) and a similar time to progression (32 vs 32 months, p=0.74). The median time to progression of group A-bi meningiomas was also comparable to that of the other 258 pooled meningiomas (32 vs 40 months, p=0.40). CONCLUSION In accordance with the 2016 WHO Classification of Tumours of the Central Nervous System, the outcome of meningiomas defined as atypical solely based on brain infiltration seems to be comparable to that of meningiomas with other criteria of atypia. Appropriate coordination between neurosurgeons and neuropathologists is mandatory to optimally assess this criterion.

The influence of lithium on the amphibian egg has been the subject of a number of investigations. From the work of Lehmann (1937), Töndury (1938), and Pasteels (1945) it is known that exposure of amphibian embryos to lithium results in a progressive cranio-caudal reduction of the central nervous system and a simultaneous conversion of the presumptive notochord into somites. Whereas these experiments were made with whole embryos, attempts have been made in recent years to localize the lithium effect by transplanting or explanting specific parts of the embryo. Gallera (1949), for instance, concluded from his experiments with transplants containing lithium treated presumptive chorda mesoderm, that lithium had reduced the ‘morphogenetic potential’ of this inductor. Lombard (1952), on the other hand, claimed that the susceptibility of amphibian eggs towards lithium was the result of the ion's direct influence on the ectoderm rather than on the presumptive archenteron roof.

Leg Movements

I. The effects of limb amputation and the cutting of commissures on the movements of the cockroach Blatta orientalis have been investigated with the aid of cinematography. Detailed analyses of changes in posture and rhythm of leg movements are given. 2. It is shown that quite marked changes occur following the amputation of a single leg or the cutting of a single commissure between the thoracic ganglia. 3. Changes following the amputation of a single leg are immediate and are such that the support normally provided by the missing leg is taken over by the two remaining legs on that side. Compensatory movements are also found in the contralateral legs. 4. When two legs of opposite sides are amputated it has been confirmed that the diagonal sequence tends to be adopted, but this is not invariably true. Besides alterations in the rhythm which this may involve, there are again adaptive modifications in the movements of the limbs with respect to the body. 5. When both comrnissures between the meso- and metathoracic ganglia are cut, the hind pair of legs fall out of rhythm with the other four legs. The observations on the effects of cutting commissures stress the importance of intersegmental pathways in co-ordination. 6. It is shown that all modifications following the amputation of legs may be related to the altered mechanical conditions. Some of the important factors involved in normal co-ordination are discussed, and it is suggested that the altered movements would be produced by the operation of these factors under the new conditions. It is concluded that the sensory inflow to the central nervous system is of major importance in the co-ordination of normal movement.

Ventricular fluids from four of 28 newborn infants who were initially seen with severe congenital anatomic defects in the central nervous system contained neutralizing antibody to at least one serotype of coxsackieviruses group B. Two of the four infants with anticoxsackieviruses group B antibody in the ventricular fluid did not have a detectable level of the same antibody(ies) in their serum. The ventricular fluid of one of the infants had immunoglobulin M neutralizing antibody directed against coxsackievirus B6. Of 11 mother-infant pairs that had neutralizing antibody to coxsackieviruses group B in both sera, nearly half had antibodies directed against more than one serotype. These data suggest the possibility of an association between congenital infections with coxsackieviruses group B and rare severe CNS defects.

Speaking about syphilis lesions of the central nervous system, it is impossible not to note that these lesions are among the most severe diseases of the latter. But, on the other hand, their severity is redeemed to some extent by the specific means of combating them which we have in our hands. In this case, the fight against neurolues is reduced not so much to its treatment as to its prevention. Hence the interest with which the question of the influence of various conditions on the occurrence of syphilitic lesions of the central nervous system has recently begun to be comprehensively discussed and the exact causes which, from the general number of syphilitics, distinguish the group subsequently condemned to neurolues have been sought to be elucidated.
