RESUMO

Rathke's Cleft Cysts (RCCs) and Craniopharyngiomas (CPs) may represent disease entities on the same etio-pathological spectrum. We report the case of a 36-year-old female presenting with vision loss and menstrual irregularities, imaging shows a predominantly cystic lesion in the sellar region with suprasellar extension. She underwent a microscopic transnasal resection of the lesion. She later presented with recurrent symptoms and increased residual lesion size on imaging, a transcranial excision of the lesion was performed. Histopathology from the initial operative specimen revealed RCC with squamous metaplasia which was BRAF negative, while the specimen from the second surgery revealed BRAF positive papillary stratified squamous architecture suggestive of Papillary CP. This case adds to the evidence that both RCCs and papillary CPs may be the spectrum of the same disease. Further, papillary CPs may be an evolution from the RCCs.

RESUMO

OBJECTIVE: To determine the prevalence of celiac disease and its predictors in children with constipation. METHODS: A hospital-based cross-sectional comparative study was conducted between November, 2018 to April, 2020. Children aged 1-12 years were screened for the presence of constipation as per ROME IV criteria and designated as cases. Age and sex matched healthy children with normal bowel habits were enrolled as comparison group. Participants underwent a detailed history and examination, and were screened for celiac disease by estimating serum anti-tissue transglutaminase IgA antibody levels (tTG-IgA). Upper gastrointestinal endoscopy and duodenal biopsy were performed in all participants who tested positive on screening (serum tTG-IgA ≥ 20 U/mL). The prevalence of celiac disease and associated factors were compared between the two groups. RESULTS: A total of 460 children (230 in each group) with mean (SD) age 64.08 (37.12) months were enrolled. Twenty-one (4.6%) children screened positive for anti tTG antibodies, among these 15 (75%) children had biopsy features suggestive of celiac disease (Marsh grade III). Children with constipation had significantly higher prevalence of celiac disease (5.65% vs 0.87%, P = 0.004) compared to children without constipation. Wasting and stunting were significantly associated with celiac disease in constipated children (P < 0.001). CONCLUSION: Children with constipation and associated growth failure have a high prevalence of celiac disease.

RESUMO

OBJECTIVES: To determine the proportion of children with severe acute malnutrition (SAM) having vitamin B12 deficiency, its clinical predictors, and its association with development. METHODS: In this cross-sectional study, 100 children between 1 mo to 59 mo [mean (SD) age 17 (12.75) mo; 55 males], with diagnosis of SAM as per WHO criteria, were included. Serum vitamin B12, serum folate, and serum ferritin levels were measured by chemiluminescence immunometric assay method, while serum Homocysteine (Hcy) level was measured by enzymatic cycling method. Development assessment was done by Denver Development Screening Tool (DDST-II). RESULTS: The mean (SD) serum vitamin B12 (cobalamin) levels were 296.52 (246.95) pg/mL; 45% children were vitamin B12 deficient (<203 pg/mL). Hyperhomocysteinemia (>14 µmol/L) was present in 39 (39%), and among these 69% (27/39) children had concomitant low serum vitamin B12 levels. Severe anemia and hypoproteinemia were significantly and independently associated with vitamin B12 deficiency [aOR (95% CI) 3.22 (1.13, 10) and 10 (1.66, 58.82), respectively]. Out of 45 children who were vitamin B12 deficient, 93%, 87%, 62% and 80% had gross motor, fine-motor, language and adaptive-cognitive delay, respectively. Vitamin B12 level was significantly associated (P <0.001) with developmental delay. CONCLUSIONS: There is a high prevalence of vitamin B12 deficiency in children with SAM, which is also associated with development delay across all domains (except language) in these children.

RESUMO

This paper offers a thorough bibliometric review of the literature on municipal solid waste compost (MSWC), focusing on the past two decades. Using an extensive dataset of 827 documents, the research patterns are analyzed via the R-based Bibliometrix package, merging metadata from Web of Science and Scopus. The analysis reveals substantial global growth in MSWC research, with a particular surge in the last 20 years. Discipline-specific journals are the main publishers, while multidisciplinary environmental outlets gained more citations. The study identifies five major collaborative author clusters that dominate productivity and citation frequency. The thematic evolution over the past five decades shows a transition from waste disposal towards topics such as heavy metals, soil properties, and plant nutrition, with emerging themes like carbon sequestration, biochar, and microplastics signaling future research directions. Specifically, the field has experienced a 7.86% annual growth rate, with an average citation rate of 26.88 per article. The 827 publications emerged from 317 sources and 1910 authors, with an international co-authorship rate of 14.75%, reflecting the field's interdisciplinary character. Thirteen primary sources and twenty-two key authors were identified as major contributors. On the geographical front, Spain and Italy led with the most contributions and highest citation count, respectively. In terms of keywords, "heavy metals" and "sewage sludge" were the most recurrent, indicating the prevailing topics in MSWC research. This analysis hence provides key insights into the evolution and future trajectory of MSWC studies.

RESUMO

Malnutrition in under-5 children (i.e., children younger than age 5 years) remains a major public health problem. Because of the reductive adaptation in children with severe acute malnutrition (SAM), changes in bone health are often subtle. We hypothesized that children with SAM have higher rates of bone resorption than bone formation, which can be assessed using bone turnover markers. In this cross-sectional comparative study, we evaluated the status of bone turnover markers, serum osteocalcin and serum tartrate-resistant acid phosphatase-5b (TRAP-5b) in under-5 children with SAM. Thirty children (6-59 months) with SAM (defined as per World Health Organization criteria) were enrolled as cases and another 30 children (age and sex matched) with normal nutritional status (weight for height -1 standard deviation [SD] to +1 SD) were enrolled for comparison of bone turnover markers. Serum TRAP-5b concentrations were significantly higher in children with SAM compared with children with normal nutritional status (mean [SD] 22.6 [15.3] vs. 11.3 [9.6], P = .009), whereas serum osteocalcin concentrations were comparable between the 2 groups (mean [SD] 40.6 [17.9] vs. 36.0 [12.5], P = .344). Frequency of hypocalcemia and vitamin D deficiency were also significantly high in children with SAM (P < .05). An inverse correlation was found between serum calcium and serum osteocalcin (r = -0.383, P < .05). Our results indicate that children with SAM have a higher bone resorption rate than children with normal nutrition status indicating compromised bone health.

RESUMO

BACKGROUND:  Fluid resuscitation with normal saline (NS) can aggravate lactate production. The objective of this study was to evaluate the efficacy of small-volume resuscitation using 3% hypertonic sodium chloride (HS) and its comparison with NS in trauma patients. The primary endpoint was an increase in lactate clearance after 1 hr of fluid resuscitation. The secondary endpoint was the incidence of hemodynamic stability, the volume of transfusion, correction of metabolic acidosis, and complications such as fluid overload and abnormal serum sodium levels. MATERIALS AND METHODS: It was a prospective, randomized, single-blind study. The study was conducted on 60 patients who arrived at the trauma center for emergency operative intervention. Inclusion criteria for patient selection were trauma victims of age more than 18 years and the requirement of emergency operative intervention for trauma except for traumatic brain injury. Patients were divided into two groups: Group HS (hypertonic saline) and Group NS (normal saline). Patients were resuscitated with either 3% HS (4ml/kg) or 0.9% NS (20ml/kg). RESULTS: The HS group had higher lactate clearance at 1 hour compared to the NS group, and this difference was statistically significant with a p-value of <0.001. When hemodynamic parameters were compared at 30 and 60 minutes after resuscitation, the HS group had a significantly lower heart rate (p<0.05 at 30 minutes and <0.001 at 60 minutes, respectively), a higher mean arterial pressure at 60 minutes (p<0.001), a higher pH at 60 minutes (p< 0.05), and a higher bicarbonate concentration at 60 minutes (p<0.05). The HS and NS groups had significant differences in serum sodium levels at 60 minutes (p<0.001). CONCLUSIONS: Resuscitation with 3% hypertonic saline improved lactate clearance. Lower volumes of fluid infusion for resuscitation achieved better hemodynamic stability and correction of metabolic acidosis in the hypertonic saline group. Our study shows that hypertonic saline can be a promising fluid for small-volume resuscitation in trauma patients with compensated mild to moderate shock.

RESUMO

Background: Awake nasotracheal fiberoptic intubation by conventional technique is time consuming and requires expertise. Complications encountered in the conventional technique sometime leads to procedure failure. Objective: The primary aim of this study was to compare the innovative technique using split nasopharyngeal airway (SNPA) with the conventional technique for nasotracheal fiberoptic intubation in terms of time taken for intubation. Method: This was a prospective, randomized, and single blind study conducted with 80 patients who were scheduled for maxillofacial surgery. Patients were randomized into two groups, group CFBI (conventional fiberoptic intubation) and group SNPA (split nasopharyngeal airway). In both the groups patients were prepared for awake fiberoptic naso-tracheal intubation. In Group CFBI (N = 41) awake naso-tracheal intubation was achieved by conventional technique of bronchoscope first approach. In Group SNPA (N = 39) spirally split nasopharyngeal airway was used first as a conduit for the passage of fiberoptic bronchoscope. The primary objective was to assess the time taken for intubation. The secondary objectives were to assess the rate of complications in the form of bleeding, cough, desaturation during the procedure, laryngospasm, and nasal bleeding. Result: The time taken for intubation was 6.15 ± 3.0 minutes in CFBI group and 3.10 ± 1.35 minutes in SNPA group and this this difference was statically significant with P value <0.001. Desaturation during the procedure was more in CFBI (99.46 ± 0.75) compared to SNPA (99 ± 0) group with significant difference P value <0.001. Conclusion: Split nasopharyngeal airway was used as conduit for the passage for the flexible fibreoptic bronchoscope and it considerably reduced the time required for fiberoptic nasotracheal intubation compared to the conventional technique of endotracheal tube first approach. Split nasopharyngeal airway provided better intubating conditions with lesser complications and superior patient comfort.

RESUMO

Reduced crop productivity results from altered plant physiological processes caused by dysfunctional proteins due to environmental stressors. In this study, a novel DnaJ Type-I encoding gene, VaDJI having a zinc finger motif in its C-terminal domain was found to be induced early upon treatment with heat stress (within 5 min) in a heat tolerant genotype of Vigna aconitifolia RMO-40. VaDJI is induced by multiple stresses. In tobacco, ectopic expression of VaDJI reduced ABA sensitivity during seed germination and the early stages of seedling growth of transgenic tobacco plants. Concomitantly, it also improved the ability of transgenic tobacco plants to withstand drought stress by modulating the photosynthetic efficiency, with the transgenic plants having higher Fv/Fm ratios and reduced growth inhibition. Additionally, transgenic plants showed a reduced build-up of H2O2 and lower MDA levels and higher chlorophyll content during drought stress, which attenuated cell damage and reduced oxidative damage. An analysis using the qRT-PCR study demonstrated that VaDJI overexpression is associated with the expression of some ROS-detoxification-related genes and stress-marker genes that are often induced during drought stress responses. These findings suggest a hypothesis whereby VaDJI positively influences drought stress tolerance and ABA signalling in transgenic tobacco, and suggests that it is a potential gene for genetic improvement of drought and heat stress tolerance in crop plants.

RESUMO

OBJECTIVE: This study endeavored to assess the lipid profile and atherogenic lipid indexes in children with transfusion-dependent thalassemia (TDT) and to compare them with matched healthy children. METHOD: The study group consisted of a total of 72 TDT patients aged 3 to14 years, while the control group had 83 age- and sex-matched healthy children. The fasting lipid profile and lipid indexes were estimated and the atherogenic index of plasma (AIP), Castelli's risk indexes I and II, atherogenic coefficient were calculated and compared between the two groups. RESULT: Compared to the control group, the mean LDL, HDL and cholesterol levels were significantly lower among the case group (p-value < 0.001). The mean VLDL and triglycerides were significantly higher in the case group (p-value < 0.001). Lipid indexes, including the atherogenic index of plasma (AIP), Castelli's risk indexes I and II and atherogenic coefficients were significantly higher in TDT children. CONCLUSION: Dyslipidemia and increased risk of atherosclerosis were found in TDT children, as they had elevated atherogenic lipid indexes. Our study underlines the importance of the routine use of these indexes in TDT children. Future studies should focus on lipid indexes in this high-lipid group of children so that preventive strategies can be planned accordingly.

RESUMO

INTRODUCTION: The association of Type 1 diabetes mellitus with autoimmune thyroid disease (AITD) has been well documented in many populations. The appearance of Anti TPO antibodies precedes thyroid dysfunction and increase in autoimmune diseases like type 1 diabetes. The occurrence of thyroid auto antibodies against microsomes (AMA) and thyroglobulin (ATA), frequently seen in Hashimoto's thyroiditis and Grave's disease have been reported in type 1 diabetes mellitus with varying frequency. MATERIALS: The present study was carried out at tertiary care centre. STUDY DESIGN: Prospective study. Duration of study: October 2014 to December 2015. STUDY POPULATION: 60 patients. RESULT: In the present study, out of 60 patients 32 (53.33%) patients were female and 28 (46.66%) were male. Out of 60 patients, 10 patients had positive titre for Anti TPO antibodies. Out of 10 patients, 6 patients were female and 4 patients were male. CONCLUSION: Anti TPO antibodies level was elevated in 10 (16.66%) patients. Out of 10 patients, 6 (60%) patients were female and 4 (40%) were male. 6 out of 10 (60%) Anti TPO positive patients had longer duration of DM1. Patients having raised Anti TPO antibodies had no relation between Anti TPO antibodies and RBS level. Though HbA1c was high in Anti TPO antibodies positive patients statistically it was not significant. Patients having raised Anti TPO antibodies level had normal TSH level.

RESUMO

BACKGROUND AND OBJECTIVES: Shigella is an important cause of diarrhea in children under five, often missed by conventional laboratory methods. Blood in stools has always been a syndromic indicator for Shigella diarrhea, but most cases present with watery diarrhea without blood. This study aimed to determine the frequency of Shigella detected by molecular and conventional methods in children under five. Additionally, we aimed to study the clinical profile and outcome of children with Shigella diarrhea managed as per current diarrhea treatment guidelines. METHODS: In this hospital-based prospective observational study, stool samples from 150 children (age range: one month to five years) with acute diarrhea (duration < seven days) were subjected to routine microscopic examination, stool culture, and DNA extraction. The extracted DNA from stored stool samples was subjected to polymerase chain reaction (PCR) amplification using a specific primer for the invasion plasmid antigen H gene sequence (ipaH) gene at 424 bp. Results were interpreted in the context of the percentage of isolation of Shigella by molecular (PCR) and conventional methods (stool microscopy and culture) and the follow-up outcome in terms of recurrence of diarrhea or dysentery and growth faltering over three months after discharge. RESULTS: Shigella infection was diagnosed in stool samples by PCR from 13 (8.7%) children, whereas it was isolated by conventional stool culture in only one (0.7%) child. The sensitivity of culture was only 7.7% against PCR for the diagnosis of Shigella infection, whereas blood in stools had a sensitivity of 15.4%. The majority of Shigella PCR-positive cases (11 out of 13) presented with non-bloody diarrhea. None of the evaluated clinical predictors had a significant association with the Shigella infection. No statistically significant difference was found between PCR-positive and PCR-negative children at the end of follow-up (P>0.05). CONCLUSION: The majority of children with Shigella infection present with watery diarrhea rather than bloody diarrhea, and a history of blood in stools is a poor marker for the diagnosis of shigellosis. The diagnostic performance of stool culture is also very low compared to stool PCR for the diagnosis of Shigella diarrhea.

RESUMO

Background: Approximately, 80% of civilian cranial gunshot injuries in India are mainly due to unlicensed mostly country-made guns, called the "Desi-Kattas," manufactured by the traditional gunsmiths. These injuries constitute a unique subgroup, with respect to the make and design along with the unique wound ballistics compared to the factory-made firearms. Objective: This study is aimed at defining the prognostic factors in predicting the outcomes related to cranial gunshot injuries due to these desi-kattas. Methods: Ten patients with kata-related cranial gunshot injury underwent surgical intervention at our institution, between 2014 and 2018. Their clinical status, imaging features, and outcomes were retrospectively analyzed. Results: Ten patients with kata-related gunshot injuries to the head were identified. Homicidal injuries were documented in six cases. Five had a GCS of 13-15 at presentation. Exit wounds were noted in 50% of the suicidal cases. Multilobar involvement was seen in 70% of cases, with the bullet crossing the midline in only 40% cases. Decompressive craniectomy was required in five cases. Eight patients had a Glasgow Outcome Score of four or more at 6 months of follow-up. There was one death during the follow-up period, while the other patient remains to be in vegetative state. Conclusion: The Katta-related cranial injuries constitute low-muzzle velocity injuries with the majority of the patients sustaining nonfatal injuries, especially homicidal. The presence of positive CT findings and the crossing of the bullet across the midline on CT brain predicts dismal prognosis. Optimal neurosurgical approach should consist of minimal local debridement and attain water seal dural closure.

RESUMO

Background: Arachnoid cysts are benign extra-cerebral congenital lesions that are thought to arise from the splitting of the arachnoid membrane. Although most arachnoid cysts remain static with advancing age, occasionally they can become symptomatic due to cyst enlargement or hemorrhage. Hemorrhage into the arachnoid cysts (intra-cystic hemorrhage) with or without associated subdural hematoma is of rare occurrence. Case Discussion: A 23-year-old male presented with a history of sudden onset severe headache while sleeping. The patient also noticed double vision, especially when looking towards the left side. Non-contrast computed tomography (NCCT) scan of the head showed left temporal pole hematoma with left Sylvian fissure bleed and bilateral fronto-temporoparietal (FTP) subacute SDH. Conclusion: Every patient with incidentally detected AC, especially in the middle cranial fossa, should be counseled regarding the risk of possible complications including hemorrhage and regular follow-up.

RESUMO

Objective: When there is a complete slippage of facet joints of C1 over C2 such that there is no contact between the articulating surfaces of C1 and C2, the condition is known as atlantoaxial spondyloptosis (AAS). AAS represents an extremely rare manifestation of atlantoaxial instability. This study was performed to highlight the presentation, radiological features, and management of unilateral AAS in pediatric patients. Material and Methods: We retrospectively identified four pediatric patients with AAS from our hospital records in the last 6 years (2014-2019). Results: Among the four patients with unilateral AAS, three were posttraumic and one was diagnosed with craniovertebral junction tuberculosis (CVJ TB). All the patients had a varying degree of spastic quadriparesis on presentation. One patient with CVJ TB presented with neck tilt. All patients with traumatic unilateral AAS were associated with an odontoid fracture. These patients underwent C1-C2 fixation with complete reduction of spondyloptosis using the techniques of joint manipulation and joint remodeling with a posterior only approach. Complete reduction of AAS in patients with trauma was also associated with the realignment of the odontoid fracture. All patients improved neurologically after surgery and achieved excellent correction of the deformity on a follow-up imaging. Conclusion: Pediatric unilateral AAS is an extremely rare phenomenon. A single-stage posterior approach with C1-C2 fixation is a feasible technique for the treatment of this seemingly difficult to correct deformity in pediatric patients and the clinical outcomes are excellent.

RESUMO

Background: Chiari 1 malformation has crowding at craniovertebral junction (CVJ), treated by Foramen magnum decompression (FMD) but is associated with high failure rates, which is explained by recently introduced concept of central instability. So, we propose a new concept of relieving this crowding without affecting stability. Objective: To derive a threshold for coring out of internal surface of C1 posterior arch instead of complete laminectomy accompanying FMD. Methods and Material: We prospectively included nine patients with a mean age of 25.33 ± 7.97 years, diagnosed with ACM-1 without AAD, who were operated with FMD and lax duraplasty and C1 laminectomy. The preoperative dural diameter and area covered under the dura at the level of C1 were measured and compared with the postoperative state. Results were analyzed to derive a cut-off threshold which could be drilled from the inner aspect of C1 arch. Results: The postoperative AP diameter of the dura increased statistically significantly from pre-op; however, the AP extension was less than the preoperative diameter with posterior arch included. Likewise, the area spanned by the dura increased statistically significantly from pre-op but was less than the cumulative area of dura with C1 arch included in pre-op. Analyzing all, a mean cut-off of 50.58% was achieved. Conclusion: The authors suggest FMD with partial coring (~50%) of the inner part of arch of C1, instead of full-thickness laminectomy with a wider length of coring as the target, and this will serve the purpose intended, without increasing mobility.

RESUMO

Background: Accuracy of screw placement is one of the important factors necessary for adequate union in odontoid fractures with malposition rates as high as 27.2% with standard techniques. Objective: To evaluate efficacy of intraoperative O-arm assistance in improving accuracy of anterior odontoid screw placement and clinco-radiological outcome in type II and III odontoid fractures. Material and Methods: In this retrospective study, surgery consisted of anterior odontoid screw fixation under intraoperative O-arm assistance over 5 years. Demographical, clinical, radiological, operative details and postoperative events were retrieved from hospital database and evaluated for fusion and surgical outcome. Results: 50 patients (Mean age 34.6 years, SD 14.10, range: 7-70 years; 44 males and 6 females) with Type II and Type III odontoid fracture underwent O-arm assisted anterior screw placement. The mean interval between injury and surgery was 12 days (range 1-65 days). Mean operating time was 132.2 min ± SD 33.56 with average blood loss of 93 ml. ±SD 61.46. With our technique, accurate screw placement was achieved in 100% patients. At the mean follow-up of 26.4 month (SD13.75), overall acceptable fusion rate was 97.8% with non-union in 2.2% patients. Morbidity occurred in two patients; one patient developed fixation failure while other patient had nonunion which was managed with posterior C1-C2 arthrodesis. We had surgical mortality in one patient due to SAH. So overall our procedure was successful in 94% patients and among patients whose follow-up was available, acceptable fusion rates of 97.8% were achieved. Conclusion: We conclude that use of intraoperative three-dimensional imaging using O-arm for anterior odontoid screw fixation improves accuracy and leads to improved radiological and clinical outcomes. It further enables us to extend the indications of odontoid screw fixation to selected complex Type II and rostral Type III odontoid fractures.

RESUMO

BACKGROUND: Studies exploring factors predicting postoperative ICU requirement in patients with coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) were not found in the literature. The aim was to evaluate the demographic profile, comorbidities, pattern of steroid received, airway assessment, and intraoperative hemodynamic perturbations associated with ICU requirement amongst patients scheduled for sinonasal debridement. METHODS: This is a retrospective cohort study. All CAM patients of ≥18 years were included. The patients' characteristics, comorbidities, pattern of steroid received, airway assessment, intraoperative hemodynamic perturbations, and outcome data were retrieved. RESULTS: A total of 130 patients were included. Thirty got admitted to ICU, out of which 26 expired. Amongst the various comorbidities, diabetes was the most common (93.85%) and was associated with higher chances of ICU requirement. Of patients with a history of steroid intake, 71% had a significantly higher risk of ICU admission. Out of 30 patients admitted to ICU, 87% (n=26) received invasive ventilation, and the rest were admitted for observation only. CONCLUSION: Middle age, uncontrolled diabetes, history of steroid intake, increased levels of serum creatinine with low potassium, and increased total leucocyte count are the independent risk factors predicting postoperative ICU admission amongst patients with CAM scheduled for sinonasal debridement.
