Abstract Background Cryoablation has been used by neurosurgeons in the past and is currently being used by other disciplines to treat kidney cancer, skin lesions, and cardiac conduction defects. Because the currently available cryogenic probes can safely create large lesions and the lesion generation (in the form of ice-ball) can be monitored on intraoperative CT images, cryoablation was used to treat large tumors in and around the sella. In this paper, the author describes a technique to perform this procedure. Main body Three large tumors in 3 patients were treated with this method. Age of the patients was 26–58 years with a male/female ratio of 2/1. Patient 1 had a non-secreting pituitary adenoma (measuring 8 × 8 cm) and presented with long-standing total visual loss in both eyes, severe headache, and seizures. She had previous resection and radiation therapy. Patient 2 had prolactinomas (measuring 5.1 × 4.6 cm) and presented with progressive loss of vision and diplopia. Patient 3 had recurrent craniopharyngioma (measuring 7.2 × 5 cm) with prior treatment with resection radiation and frequent drainage of the cyst. He presented with headache and progressive worsening of his vision. The procedure was done on the CT table with intraoperative scans, using Patil stereotactic frame and argon cryoablation probe (Healthtronics). 3-D images were used to plan targets and trajectories. The probe was placed at the target via a trans-nasal trans-sphenoidal route. One to 3 lesions measuring 2.5–3 cm in diameter were made to ablate the tumor. Ice-ball formation was monitored live on CT images. There is no complication. One patient had near-complete resolution of the tumor, two had partial resolution of their tumors, and all had resolution of their presenting symptoms at follow-up of 3–24 months (median 6 months). In one patient, symptoms reoccurred due to the formation of new tumor masses. Short conclusion Cryoablation of intracranial tumors and can be done safely and effectively. Live monitoring of lesion generation using CT imaging is a major advantage of this technique.

<p class="abstract"><strong>Background:</strong> Herpes zoster results from the reactivation of varicella-zoster virus lying dormant in the dorsal root ganglia following an earlier primary infection (chickenpox), usually in childhood. The reactivation occurs due to multifactorial causes leading to decreased immunity.</p><p class="abstract"><strong>Methods:</strong> This study was conducted on 109 cases of herpes zoster. Patient’s particulars were noted. A detailed history was recorded; morphology, the site and side of skin lesions were recorded. Any other associated diseases were noted.<strong></strong></p><p class="abstract"><strong>Results:</strong> Out of 109 patients 66 were male and 43 were female. The total of 53 (48.6%) patients were under the age of 40 years and 56 (51.4%) patients above 40 years. Bhutias were affected in highest number (18.4%) followed by Sharma community (15.6%). The ophthalmic division of trigeminal nerve was the most commonly affected single nerve with 13.8% followed by T10 and T7 dermatome at 9.17% and 7.3% respectively. Thoracic nerves the most commonly involved thoracic nerves with 44 cases. Single dermatomal eruptions were found in 55 patients. The dissemination of herpes zoster was although very rare but was present in three patients. Type 2 diabetes mellitus was the common associated systemic illness with 10.09% of patients.</p><p class="abstract"><strong>Conclusions:</strong> From this study it was revealed that both young adults and older age group people were affected almost equally. The male: female ratio was 1.5:1 with Bhutia community being mostly affected. Thoracic dermatome was the most common dermatome involved and in half the patients some form of associated disease noted.</p>

ABSTRACT Introduction: Leprosy affecting the nerve solely or with concomitant skin lesions is not an uncommon condition in clinical practice. It is responsible for extensive morbidity and often poses a diagnostic challenge. This study aims to highlight the clinicopathological features of Hansen's neuritis (HN). Materials and Methods: In this retrospective study, cases of histologically diagnosed HN, from January 2010 to July 2017, were reviewed in the light of clinical features, treatment history, and outcome. Results: There were 18 cases of HN which accounted for 3.97% of total nerve biopsy samples (n = 453) and 0.02% of total histopathology samples (n = 81,013). The male: female ratio was 5:1 in the cases of HN. Age range was 20–79 years with a mean age of 42.4 years (standard deviation: ±14.03). Among the HN cases, there were 13 cases of pure neuritic leprosy (61.1%). Mononeuritis multiplex was the most common finding in the nerve conduction study. Six (33.3%) cases exhibited histological features of borderline tuberculoid leprosy, followed by five (27.8%) cases of mid-borderline features, three (16.7%) cases each of borderline lepromatous and burnt-out HN, and one (5.6%) case of polar tuberculoid leprosy. Lepra bacilli were detected on Fite-Faraco stain in 44.4% cases. Conclusion: Diagnosis of HN depends on astute search for skin lesions, nerve thickening or tenderness, sensory or motor symptoms, histopathological examination, and demonstration of lepra bacilli.

ABSTRACT Background: Primary spinal cord tumors are not as frequently encountered as their cranial counterparts. They could present in such an indolent manner that requires a reasonable index of suspicion for their diagnosis to be considered. Objective: The objective of this study is to analyze the incidence and pattern of primary spinal cord and appendage neoplasms in patients surgically treated in our institution over a decade of practice. Materials and Methods: A retrospective review of clinical, radiological, and histopathology profiles of patients surgically treated for primary spinal cord tumor from 2006 to 2016 was carried out. Retrieved data were analyzed using SPSS version 21. Results: Out of 472 spine procedures were performed within the study period 17 (3.6%) cases of histologically proven primary spinal cord tumors were identified. The age of patients ranged between 17 and 77 years with a mean age was 45 years. The male: female ratio was 1:1.1. Motor deficit and pain were the most common presenting symptoms seen in 35.3% and 29.4% of patients, respectively. Meningiomas are the most common histological diagnosis (70.6%), distantly followed by Schwannoma (17.6%). The most common location of the tumors was intradural extramedullary (70.6%). All patients had gross total resection of tumor with no perioperative mortality. Conclusion: Meningioma is the most common surgically treated primary spinal cord tumor in our setting. Surgery is associated with good outcome.

The epidemiological and clinical features of Creutzfeldt-Jakob disease have never before been studied in Scotland and Northern Ireland. Case records for those dying with this diagnosis were obtained for the period 1980–89. Over the ten year period, 25 definite or probable cases were identified, giving an annual incidence of 0.37 cases/million. There were more cases in the second half of the decade, and this was most likely due to increased ascertainment. One pair of cases occurred in close proximity to each other. Sex distribution showed an excess of males (male female ratio = 1.8: 1). Mean age at onset was 65.2 years, and mean duration of disease was 5.3 months. The presenting symptoms and clinical features were similar to those noted in previous studies of other populations. There was no excess of cases in occupations linked to food, farming, or medical/paramedical work.

The author examined completed suicides occurring over a period of 25 years in a county of Hungary with a traditionally low (relatively speaking) suicide rate of 25.8. The rates are clearly higher in villages than in the towns. The male/female ratio was close to 4:1, among elderly though only 1.5:1. The high risk groups are the elderly, divorced, and widowed. Violent methods are chosen in 66.4% of the cases. The rates are particularly high in the period April-July. Prior communication of suicidal intention was revealed in 16.3% of all cases. Previous attempts had been undertaken by 17%, which in turn means that 83% of suicides were first attempts. In our material 10% the victims left suicide notes. Psychiatric disorders were present in 60.1% of the cases, and severe, multiple somatic illnesses (including malignomas) were present in 8.8%. The majority of the data resemble those found in the literature.

Abstract BACKGROUND Medulloblastoma (MB), the most malignant brain tumor of childhood has survival outcomes exceeding 80% for standard risk and 60% for high risk patients in high-income countries (HIC). These results have not been replicated in low-to-middle income countries (LMIC), where 80% of children with cancer live. Brazil is an upper-middle income country according to World Bank, with features of LMIC and HIC. METHODS We conducted a retrospective review of 126 children (0–18 years) diagnosed with MB from 1997 to 2016 at INCA. Data on patients, disease characteristics and treatment information were retrieved from the charts and summarized descriptively; overall survival (OS) and event-free survival (EFS) were calculated using the Kaplan-Meier Method. RESULTS The male/female ratio was 1.42 and the median age at diagnosis was 7.9 years. Headache (79%) and nausea/vomiting (75%) were the most common presenting symptoms. The median time from onset of symptoms to surgery was 50 days. The OS for standard-risk patients was 69% and 53% for high-risk patients. Patients initiating radiation therapy within 42 days after surgery (70.6% versus 59.6% p=0.016) experienced better OS. Forty-five patients (35%) had metastatic disease at admission. Lower maternal education correlated with lower OS (71.3% versus 49% p=0.025). Patients who lived &gt;40km from INCA fared better (OS= 68.2% versus 51.1% p=0.032). Almost 20% of families lived below the Brazilian minimum wage. CONCLUSIONS These findings suggest that socioeconomic factors, education, early diagnosis and continuous data collection, besides oncological treatment must be adressed to improve the survival of children with MB.

Abstract Background Road traffic accident (RTA) is the eighth leading cause of death worldwide. Motorcycle-associated head injury is the leading cause of road traffic associated morbidity and mortality in developing countries. Even though the incidence and mortality of head injury from motor cycle crash is on the increase in developing countries, especially in the African continent, most of the studies published in the literature on this subject matter took place in the developed Western countries. Methods This is a retrospective cross-sectional study of data from patients managed in our institution between December 2014 and November 2016. Results One hundred and eighty-four patients were analyzed. None of the patients used safety helmet for protection. The mean age was 27.6 ± 17.2 years with male female ratio of 6.7:1. Lone crash by cyclists and collisions accounted for 66.8% and 33.1% of the cases, respectively. Passengers and riders comprised 75% of the patients, while 25% were vulnerable pedestrians. The most frequently abused substance by the patients was tramadol (65.52%). Severe head injury and pupillary abnormality were found in 23.9% and 45.5% of the patients, respectively. Cranial CT scan showed abnormalities in 40.2% of the patients. Surgery was done in 28.3% of the patients with mortality rate of 20.7%. Conclusions The use of motorcycle as a mean of transportation has caused significant negative impact on the society. Young people, who constitute the workforce, are majorly affected, and this invariably leads to a serious economic burden on the concerned families and communities.

Background:During the last decade, the treatment of chronic inflammatory rheumatism (CIR) has been greatly improved with the advent of biotherapy.However, the use of biological treatment can lead to a number of side effects including abnormalities in the blood count.Objectives:The aim of this study was to assess the different hematological side effects of biological treatment in patients with rheumatoid arthritis (RA) and spondyloarthitis (SA).Methods:This study included patients with RA (ACR/EULAR 2010) and SA (ASAS 2009) registred with the Tunisian Biologic National Registry (BINAR).Patients were followed and treated with biologics for 2 years of less. Clinical data relative to biological treatment, including haematological side effects, have been collected.Results:Two hundred and ninety-eight patients (178 women and 111 men) were included in the study.The mean age was 49.2 ± 14.1 years. The male/female ratio was 0.6. The mean diseases durations for RA and SA were respectively 6.7 ± 3.5 years and 6.5 ±3.6 years.Anti-TNFα agents were prescribed in 87.9% of patients (n = 263) with respectively: Infliximab (20.4%) Etanercept (23.1%), Adalimumab (24.6%) and Certolizumab (26.5%).Tocilizumab and Rituximab were prescribed in 10.4% and 5% of the patients, respectively.Blood count abnormalities were noted in 15.4 % of patients (n=46).Neutropenia was the most frequently anomaly met on the hemogram (9.1%) followed by anemia (3.4%) and thrombocytopenia (3%). Pancytopenia was found in 11.4% of patients (n=34).The median time between biological therapy initiation and the onset of hematologic manifestations was 4.8 months [1-12]. Biological treatment was interrupted in two patients.In the other cases, the biological treatment was maintained with close monitoring of blood cell count. No case of death related to these hematological disturbances has been reported.Conclusion:In our registry, hematological side effects of biological treatment were found in 15.4% of cases and were noted with a median delay of 4.8 [1-12] months after the treatment initiation. Further studies are needed to confirm our preliminary results.Disclosure of Interests:None declared
