Cognitive and behaviour dysfunction of children with neurocysticercosis: a cross-sectional study.

Eighty-three confirmed cases of neurocysticercosis diagnosed as per modified delBrutto criteria were enrolled in the study (Group-I) to observe cognitive and behavioural changes. Controls consisted of two groups: children with idiopathic generalized tonic-clonic seizure (Group-II) and normal children with non-specific cough (Group-III). Cases and controls were subjected to cognitive and behaviour assessment. There was significant difference in the intelligence quotient (IQ) of cases in domains of visual perception, immediate recall, analysis synthesis and reasoning, verbal ability, memory and spatial ability. In the age group of 6-18 years, cases had significantly more behaviour problems than control without seizure, in domains of anxious depressed, withdrawn depressed, somatic problems, social problems and rule-breaking behaviour. Neurocysticercosis causes decline in cognitive function and behaviours in older children, which should be recognized early for appropriate management and to avoid undue parental anxiety.

Heavy and trace metals in carcinoma of the gallbladder.

BACKGROUND: Carcinoma of the gallbladder is the commonest malignancy of the biliary tract in northern India The etiologic relation of specific metals (heavy and trace) and their compounds to neoplasia has been a topic of investigation for some time but not adequately described for carcinoma of the gallbladder. The aim of the present study was to evaluate the relation of heavy and trace metals to this malignancy. METHODS: The levels of selenium, zinc, copper, manganese, cadmium, chromium, lead, and nickel were estimated in serum, bile, gallstones, and gallbladder tissue using atomic absorption spectrophotometry. The tests were carried out in 30 patients with gallbladder cancer and 30 sex-matched patients with cholelithiasis. RESULTS: Selenium and zinc levels were significantly reduced (p < 0.001) and copper concentration was found to be significantly higher (p < 0.001) in serum, bile, and gallbladder tissue from patients with carcinoma of the gallbladder. Lead, cadmium, chromium, and nickel levels were elevated in serum and bile in patients with carcinoma of the gallbladder. CONCLUSIONS: The present study demonstrated a significant decrease in serum, biliary, and tissue levels of selenium and zinc but increased copper, lead, cadmium, chromium, and nickel levels in patients with carcinoma of the gallbladder, indicating a strong relation between the concentrations of these metals and gallbladder cancer.

Clinico-epidemiological profile and treatment outcome in adolescents and young patients of rectal cancer attending a tertiary cancer center.

INTRODUCTION: The incidence of colorectal cancer in young adults is on an increasing trend. It is observed that this subgroup of patients has an aggressive disease and carries a poorer prognosis compared to its older counterpart. This study aimed to analyze the incidence, treatment outcome, and prognostic factors in adolescents and young adults with rectal cancer attending a tertiary cancer center in North India. MATERIALS AND METHODS: We retrospectively analyzed 50 patients of histologically proven rectal cancer, aged up to 30 years, treated at our center between 2015 and 2019. The clinical, demographic, and pathological parameters were studied in all these patients. Kaplan-Meier survival analysis was used to find out survival. Univariate analysis was performed to assess prognostic factors. RESULTS: The incidence was 26.4% at our center with a median age of 28 years. Bleeding per rectum was the commonest complaint. Most of them had signet ring cell histology (26%). The median overall survival was 16 months. Survival was significantly better in patients having bleeding per rectum as an initial complaint (P = 0.009), absence of lymphovascular invasion (LVI) (P = 0.005), and perineural invasion (PNI) (P = 0.002), who received complete planned treatment compared to patients who could not receive either of the modality (P < 0.001). Patients who did not receive radiotherapy (RT) had the worst outcomes compared to those who received RT in any form. RT dose of 50.4 Gy was found to be superior as compared to other schedules. There was no significant difference in survival with gender, tumor stage, grade, type of surgery, or chemotherapy regimen. CONCLUSION: The majority of patients presented in an advanced stage. Therefore, bleeding per rectum should be properly and timely investigated in all these young patients. Early detection and complete treatment are paramount to improving the outcome.

Evaluation of survival outcomes and prognostic factors of carcinoma anal canal at a tertiary cancer center.

CONTEXT: Concurrent chemoradiotherapy is considered a standard of care for patients with carcinoma anal canal. Being an unusual malignancy, there is limited Indian data regarding survival outcomes and prognostic factors. AIM: To evaluate survival outcomes and associated prognostic factors in patients with carcinoma anal canal treated with radical intent. METHODS AND MATERIAL: Patients with squamous cell carcinoma of the anal canal, treated with radical intent between 2015 and 2019 were included in the study. Data regarding the baseline characteristics of the patients and treatment outcomes were collected and analyzed. Survival rates were estimated using Kaplan-Meier method. To determine survival difference between the groups, log-rank test was used. Multivariate analyses were performed with Cox proportional hazard models and P value < 0.05 was considered significant. RESULTS: Forty-two patients were identified after applying suitable eligibility criteria. The median age was 55 years (range: 26-80 years).The median follow-up duration was 23.5 months (range: 1.9-51.9 months). The 3-year overall survival (OS), disease-free survival (DFS), and locoregional (LRC) were 78.5%, 53.1%, and 66.4%, respectively. On multivariate analysis, inferior DFS was significantly affected by lack of concurrent chemotherapy (CT) (hazard ratio [HR], 11.50; 95% confidence interval [CI], 1.92-68.78; P = 0.007) and radiotherapy (RT) dose of 45 Gy or less (HR, 35.96; 95% CI, 6.32-204.56; P = 0.000). CONCLUSION: For patients of carcinoma anal canal, concurrent CT and RT dose are independent prognostic factors influencing DFS.

Coagulation status and platelet functions in children with severe falciparum malaria and their correlation of outcome.

This study was undertaken to observe the changes in coagulation and platelet profile, and findings were correlated with their outcome. Forty consecutive children with severe falciparum malaria were studied for their coagulation status, i.e. prothrombin time (PT), activated thromboplastin time (APTT), thrombin time (TT) and anti-thrombin-III (AT-III), platelet profile (platelet count, platelet aggregation with adenine diphosphate (ADP) and ADR and PF3 availability). Derangements in the coagulation profile in the form of increased PT, APTT and/or TT were seen in 47.5, 35 and 62.5% cases, respectively, but bleeding was seen in only six cases. Thrombocytopenia was found in 34 patients. Platelet aggregation with ADP and ADR revealed hypoaggregation in 95.3 and 97.5% cases, respectively, and were statistically significant. Platelet factor-3 availability was also significantly prolonged. Patients with prolonged PT, PF-3 and hypoaggregation with adrenaline had 1.4, 1.7 and 1.45 times higher risk of mortality.

Doppler ultrasound scoring to predict chemotherapeutic response in advanced breast cancer.

BACKGROUND: Doppler ultrasonography (US) is increasingly being utilized as an imaging modality in breast cancer. It is used to study the vascular characteristics of the tumor. Neoadjuvant chemotherapy is the standard modality of treatment in locally advanced breast cancer. Histological examination remains the gold standard to assess the chemotherapy response. However, based on the color Doppler findings, a new scoring system that could predict histological response following chemotherapy is proposed. METHODS: Fifty cases of locally advanced infiltrating duct carcinoma of the breast were studied. The mean age of the patients was 44.5 years. All patients underwent clinical, Doppler and histopathological assessment followed by three cycles of CAF (Cyclophosphamide, Adriamycin and 5-Fluorouracil) chemotherapy, repeat clinical and Doppler examination and surgery. The resected specimens were examined histopathologically and histological response was correlated with Doppler findings. The Doppler characteristics of the tumor were graded as 1-4 for <25%, 25-50%, >50% and complete disappearance of flow signals respectively. A cumulative score was calculated and compared with histopathological response. Results were analyzed using Chi square test, sensitivity, specificity, positive and negative predictive values. RESULTS: The maximum Doppler score according to the proposed scoring system was twelve and minimum three. Higher scores corresponded with a more favorable histopathological response. Twenty four patients had complete response to chemotherapy. Sixteen of these 24 patients (66.7%) had a cumulative Doppler score more than nine. The sensitivity of cumulative score >5 was 91.7% and specificity was 38.5%. The area under the ROC curve of the cumulative score >9 was 0.72. CONCLUSION: Doppler scoring can be accurately used to objectively predict the response to chemotherapy in patients with locally advanced breast cancer and it correlates well with histopathological response.

Oxidative stress in children with neurocysticercosis.

BACKGROUND: Free radicals can cause neuronal injury and play an important role in pathogenesis of neurocysticercosis. This study was done to evaluate oxidative stress (antioxidants and oxidants) in cerebrospinal fluid (CSF) of children with neurocysticercosis and to observe their correlation with the type of seizure and outcome. METHODS: Forty consecutive confirmed cases of neurocysticercosis were evaluated for their markers of reactive oxygen species, that is, oxidants (malondialdehyde, protein carbonyl and nitrite) and antioxidant (superoxide dismutase, glutathione peroxidase, ceruloplasmin, ascorbic acid, copper and zinc) concentrations in CSF. An equal number of children, age and sex matched with an idiopathic generalized tonic-clonic seizure, were studied as controls. RESULTS: Generalized tonic-clonic seizure (65%) was the most common presentation, and a single ring-enhancing lesion in the parietal lobe was the most common finding in cranial imaging. Oxidants such as malondialdehyde, protein carbonyl and nitrite in CSF were significantly elevated (P < 0.001), whereas antioxidants such as superoxide dismutase, glutathione peroxidase, ceruloplasmin, ascorbic acid, copper and zinc levels were significantly lower (P < 0.001) in children with neurocysticercosis than in controls. There were insignificant differences in oxidant and antioxidant value in CSF in relation to the type of seizure, number and location of lesion in cerebral cortex and antiepileptic therapy. CONCLUSION: The significantly elevated malondialdehyde, nitrite and protein carbonyl values reflect increased oxidative stress, whereas decreased concentrations of glutathione peroxidase, ascorbic acid, zinc, copper, ceruloplasmin and superoxide dismutase point toward utilization of the antioxidants in neurocysticercosis. The observed changes in oxidants and antioxidants suggest the production of reactive oxygen species such as superoxide, hydrogen peroxides and hydroxyl radicals and their possible role in pathogenesis of neurocysticercosis.

Sex estimation from the mastoid process among North Indians.

Determination of sex from fragmentary crania is a critical problem in forensic anthropology. Osteometric analysis of mastoid can serve forensic anthropologists better in sex identification by virtue of the noticeable dimorphic characteristics. The present study aims to develop population-specific, sex-differentiating anthropometric standards for the mastoid process of North Indian skulls. Eight parameters of the mastoid region were measured on 138 adult crania (M/F 104:34, 22-65 years) and analyzed using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.000). In stepwise analysis, asterion-mastoidale and mastoid breadth have provided an accuracy of 87%. Receiver operating characteristic curves were obtained for each variable to observe their overall performance in sex determination. Posterior end of incisura mastoidea-depression of suprameatal triangle was found to be the best variable with maximum area under curve and highest predictive accuracy (82.6%).

Mandibular ramus: an indicator for sex in fragmentary mandible.

Mandible is the hardest and most durable bone of the skull exhibiting a high degree of sexual dimorphism. Especially ramus of mandible is subjected to greater stress than any other bone of the skull because of the process of mastication. This study has been performed to establish the osteometric standards for practical use in forensic context over Indian population using mandibular ramus. The sample consists of 116 mandibles of Northern Indian population (M:F; 92:24, mean age 37.4 years), collected from the Department of Forensic Medicine, IMS, BHU, Varanasi. Osteometric informations about five metric parameters (coronoid height, projective height, condylar height, and maximum breadth and minimum breadth of ramus) were taken with sliding calipers. These parameters were subjected to different discriminant function analysis using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.001 in all cases) with an overall accuracy of 80.2%, and coronoid height was the single best parameter providing an accuracy of 74.1%.

An osteometric study of northern Indian populations for sexual dimorphism in craniofacial region.

Sex identification is an initial crucial objective in the revelation of the complete identity of the human skeleton as it also renders significantly clearer guidance towards age and stature estimation. Population specific standards are of great practical relevance in the present era of increasing population intermixing. Size differences and robusticity are the two well-elaborated pillars holding most of the dimorphic burdens of the skull. This study is designed to explore dimorphic characteristics of the craniofacial region to establish anthropometric standards for contemporary North Indian populations, which have not been available so far. One hundred and twelve adult crania of known age (23-65 years) and sex (M:F; 82:30) were collected in the Department of Forensic Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. Ten standard metric parameters of craniofacial region were measured and subjected to stepwise and direct discriminant function analysis employing SPSS 16.00. Bizygomatic breadth emerged as the single best parameter in stepwise analysis, providing an average accuracy of 85.5%.

Effects of picture exchange communication system on communication and behavioral anomalies in autism.

Communication skills deficits and stereotyped behaviors are frequently found among people with pervasive developmental disabilities like autism. These communication and behavioral oddities of autism are often considered to be difficult to treat and are challenging. Picture exchange communication system (PECS) is a six-phase picture system based on applied behavior analysis and is specially designed to overcome these communication difficulties in children with autism by encouraging the child to be the communication initiator. The present paper throws light on the process of using PECS along with other traditional behavioral approaches in managing communication deficits and behavioral stereotypies in a seven-year-old male child diagnosed as having childhood autism. The identified target behaviors of repeated head turning, flapping his hands, poor communication skills were assessed using various rating scales including visual analogue scale as per clinician observation and parental reports and managed using PECS as an adjunct to traditional behavioral techniques of contingency management, differential reinforcement, task direction and reprimand. Outcome was assessed using same tools after thirty-two sessions of interventions spread over three months. Significant improvements of around 60% were observed in the target behaviors.

Caregiver burden and coping: a prospective study of relationship between burden and coping in caregivers of patients with schizophrenia and bipolar affective disorder.

INTRODUCTION: Caregivers of patients of schizophrenia and bipolar affective disorder (BAD) experience considerable burden while caring their patients. They develop different coping strategies to deal with this burden. Longitudinal studies are required to assess the relationship between caregiver burden and coping. AIM: The present study was conducted to assess relationship between burden and coping in caregivers of clinically stable patients with schizophrenia and BAD. METHOD: One hundred patients each of schizophrenia and BAD attending a psychiatric outpatient setting and their caregivers were followed up for a period of 6 months. Burden and coping strategies were assessed in the caregivers at baseline, and after 3 and 6 months using the Burden Assessment Schedule (BAS) and Ways of Coping Checklist - Hindi Adaptation (WCC - HA). RESULTS: Burden remained stable over 6 months and was comparable in the two groups of caregivers. Caregivers from both the groups were found to use problem focused coping strategies more often than seek social support and avoidance strategies. Scores on avoidance type of coping showed a positive correlation with the total burden scores and a number of burden factors. CONCLUSION: Caregivers of patients of schizophrenia and BAD face similar levels of burden and use similar types of coping methods to deal with it. Relationship between caregiver burden and coping is quite complex.
