RESUMO
Accidental injuries in the pediatric population are common. The response to injury also differs owing to anatomical and physiological differences in children. While such injuries carry a risk of lifelong morbidity, some cases may follow a benign course despite their distressing appearance. We report two cases of accidentally incurred penetrating trauma in the pediatric population with unusual objects, including a pencil and a toy wheel. Despite their intracranial extension, neither of the patients exhibited any discernible neurological deficits. Penetrating brain injuries require early removal and meticulous perioperative care to minimize the risk of long-term adverse neurological events in children.
RESUMO
In photocatalytic removal of organic pollutants, adsorption and degradation are two important processes that take place. Various instrumental techniques and trapping experiments have been used to identify the reactive species and the mechanism of photodegradation. The present work focuses on investigating the mechanism of photo-induced degradation from the comparative characterization of fresh and used samples, isotherm models, competitive adsorption, and desorption studies of pure and Ag+-modified TiO2 NPs. The comparative characterizations of fresh and used NPs were carried out with FT-IR, EDX, and XRF analyses after methylene blue (MB) degradation. The Ag+ doped TiO2 used in this study was fabricated using simple impregnation technique. The prepared NPs were characterized using techniques including XPS, XRD, SEM/EDX, XRF, UV-DRS, and pH point-zero charge analyses (pHPZC). The Ag+-modified TiO2 NPs showed improved efficiency compared to pure TiO2 NPs using normal compact fluorescent light (CFL). The Langmuir and Freundlich isotherm models were applied to test the adsorption behavior on the surface photocatalysts. The investigational data finest fitted to the Langmuir isotherms model compared to Freundlich model, suggesting the homogeneous monolayer adsorption followed by degradations. The competitive removal of MB in the presence of a photo-generated electrons trapper (Cd2+) was enhanced almost 3-folds (115 mg/L) compared to the removal from a single MB solution (40 mg/L). The characterization of the used samples as well as adsorption in the dark and negligible desorption of used samples support the involvement of the proposed photo-induced degradation mechanism.
RESUMO
Pyometra is a potentially life-threatening condition that affects intact female dogs in their middle to advance age. Timely diagnosis and appropriate treatment are critical for the survival of patients, especially when pyometra advances to sepsis. This study aimed to investigate the prognostic potential of certain haematology, serum biochemical and inflammatory biomarker, secretory leucocyte protease inhibitor (SLPI) for pyometra in bitches (n = 41). Blood samples were collected after clinical diagnosis of pyometra for haematology and serum biochemistry. Based on the prognosis following medical/surgical treatment, animals were retrospectively categorized into survivor (n = 29) and dead (n = 12). Endometrial tissue sections were obtained from the bitches undergoing ovariohysterectomy (n = 21). Serum concentration of SLPI was quantified using sandwich ELISA and its expression in the endometrium was investigated using RT-qPCR. A marked increase in the total leucocyte count (TLC), neutrophils, blood urea nitrogen (BUN) and serum creatinine was observed in the female dogs that did not survive. Significant elevation in the serum SLPI concentration (3.49 ± 0.44 vs. 2.38 ± 0.13 ng/mL) was observed in the bitches those died after the treatment, in comparison to those survived (p < .01). Additionally, there was a notable upregulation of SLPI in the endometrium in the bitches those died due to pyometra. Based on the ROC analysis results, it was observed that a cut-off concentration of 2.93 ng/mL for SLPI, 27.77 mg/dL for BUN and 16.3 × 103 /µL for TLC could effectively distinguish the prognosis of pyometra-affected dogs. From this study, it can be concluded that upregulation of SLPI in the endometrium and its elevated concentration in peripheral circulation along with TLC and BUN concentration could serve as valuable indicators for predicting the prognosis of pyometra in bitches.

BACKGROUND: Retinitis Pigmentosa (RP) is a clinically and genetically progressive retinal dystrophy associated with severe visual impairments and sometimes blindness, the most common syndromic form of which is Usher syndrome (USH). This study aimed to further increase understanding of the spectrum of RP in the Khyber Pakhtunkhwa region of Pakistan. METHODOLOGY: Four consanguineous families of Pashtun ethnic group were investigated which were referred by the local collaborating ophthalmologists. In total 42 individuals in four families were recruited and investigated using whole exome and dideoxy sequencing. Among them, 20 were affected individuals including 6 in both family 1 and 2, 5 in family 3 and 3 in family 4. RESULT: Pathogenic gene variants were identified in all four families, including two in cone dystrophy and RP genes in the same family (PDE6C; c.480delG, p.Asn161ThrfsTer33 and TULP1; c.238 C > T, p.Gln80Ter) with double-homozygous individuals presenting with more severe disease. Other pathogenic variants were identified in MERTK (c.2194C > T, p.Arg732Ter), RHO (c.448G > A, p.Glu150Lys) associated with non-syndromic RP, and MYO7A (c.487G > A, p.Gly163Arg) associated with USH. In addition, the reported variants were of clinical significance as the PDE6C variant was detected novel, whereas TULP1, MERTK, and MYO7A variants were detected rare and first time found segregating with retinal dystrophies in Pakistani consanguineous families. CONCLUSIONS: This study increases knowledge of the genetic basis of retinal dystrophies in families from Pakistan providing information important for genetic testing and diagnostic provision particularly from the Khyber Pakhtunkhwa region.

As onset of sepsis adversely affects the prognosis of canine pyometra, finding biomarkers that would distinguish sepsis status would be useful in the clinical management. Accordingly, we hypothesized that differential expression of endometrial transcripts and circulating concentration of certain inflammatory mediators would discriminate pyometra-led sepsis (P-sepsis+) from those of pyometra without sepsis (P-sepsis-). Bitches with pyometra (n = 52) were classified into P-sepsis+ (n = 28) and P-sepsis- (n = 24) based on vital clinical score and total leukocyte count. A group of non-pyometra bitches (n = 12) served as control. The relative fold changes in the transcripts of IL6, IL8, TNFα, IL10, PTGS2, mPGES1 and PGFS, SLPI, S100A8, S100A12 and eNOS were determined by quantitative polymerase chain reaction. Furthermore, the serum concentrations of IL6, IL8, IL10, SLPI and prostaglandin F2α metabolite (PGFM) were assayed by ELISA. The relative fold changes in S100A12 and SLPI and mean concentrations of IL6 and SLPI were significantly (p < .05) higher in P-sepsis+ than that of P-sepsis- group. Receiver operating characteristic analysis revealed that serum IL6 had a diagnostic sensitivity of 78.6% and a positive likelihood ratio (LR+) of 2.09, at a cut-off value of 15.7 pg/mL to diagnose P-sepsis+ cases. Similarly, serum SLPI had a sensitivity of 84.6% and an LR+ of 2.23, at a cut-off value of 2.0 pg/mL. It was concluded that SLPI and IL6 would serve as putative biomarkers for pyometra-led sepsis in bitches. Monitoring SLPI and IL6 would be a useful adjunct to the established haemato-biochemical parameters in customizing the treatment strategies and arriving at the decision for management of pyometra bitches with critical illness.

COVID-19 and a low vitamin D state share common risk factors, which might explain why vitamin D deficiency has been linked with higher COVID-19 mortality. Moreover, measures of serum vitamin D may become lower during systemic inflammatory responses, further confounding the association via reverse causality. In this prospective study (recruited over 12 months), we examined whether the association between a low vitamin D state and in-hospital mortality due to SARS-CoV-2 pneumonia in unvaccinated subjects is explained by (i) the presence of shared risk factors (e.g., obesity, advanced age) or (ii) a reduction in serum 25(OH)D due to COVID-19 (i.e., reverse causality). In this cohort of 232 (mean age = 56 years) patients (all had SARS-CoV-2 diagnosed via PCR AND required supplemental oxygen therapy), we failed to find an association between serum vitamin D and levels of CRP, or other inflammatory markers. However, the hazard ratio for mortality for subjects over 70 years of age (13.2) and for subjects with a serum 25(OH)D level less than 30 nmol·L−1 (4.6) remained significantly elevated even after adjustment for gender, obesity and the presence of diabetes mellitus. Subjects <70 years and >70 years had significantly higher mortality with a serum 25(OH)D less than 30 nmol·L−1 (11.8% and 55%), than with a serum 25(OH)D greater than 30 nmol·L−1 (2.2% and 25%). Unvaccinated Caucasian adults with a low vitamin D state have higher mortality due to SARS CoV-2 pneumonia, which is not explained by confounders and is not closely linked with elevated serum CRP.

Ceramics-based filter for water treatment is an ancient technology to procure potable water at the household level. The traditional clay pots (vessels or hollow cylindrical container) have been used since long in the developing countries. The ceramic material (CaCu3Ti4O12 or CCTO) is a hetero-junction of titanium oxide, a well-known UV-active photocatalyst, and visible light absorbing CuO materials. This hetero-junction is able to overcome the limitations such as high bandgap, poor stability, low efficiency, and high photo-generated charge (e-/h+) recombination rate, associated with the other commonly used metal oxide semiconductor photocatalysts. Moreover, the low-cost, viable and facile synthesis routes for CCTO triggered its potential applications in photoelectrochemical and photocatalytic processes. This review will elaborate on the available literature demonstrating the visible light activity of CCTO photocatalysts in water treatment technologies. Furthermore, the mechanism of photocatalysis and synthesis routes are presented in this work for broader impact of the CCTO potential applications. The extended porous character and excellent surface texture have made the ceramic materials as an ideal choice to combat the bacteria, pathogens and turbidity in aqueous medium at household level. Specifically, the controlled size and shape make the CaCu3Ti4O12 (CCTO) an excellent visible light-driven photocatalyst, involving highly reactive species such as â¢OH, â¢O2- anions, h+, and e-, for the removal of organic and inorganic pollutants from water.

AIM: To investigate the genetic basis of autosomal recessive retinitis pigmentosa (arRP) in two consanguineous/ endogamous Pakistani families. METHODS: Whole exome sequencing (WES) was performed on genomic DNA samples of patients with arRP to identify disease causing mutations. Sanger sequencing was performed to confirm familial segregation of identified mutations, and potential pathogenicity was determined by predictions of the mutations' functions. RESULTS: A novel homozygous frameshift mutation [NM_000440.2:c.1054delG, p. (Gln352Argfs*4); Chr5:g.149286886del (GRCh37)] in the PDE6A gene in an endogamous family and a novel homozygous splice site mutation [NM_033100.3:c.1168-1G>A, Chr10:g.85968484G>A (GRCh37)] in the CDHR1 gene in a consanguineous family were identified. The PDE6A variant p. (Gln352Argfs*4) was predicted to be deleterious or pathogenic, whilst the CDHR1 variant c.1168-1G>A was predicted to result in potential alteration of splicing. CONCLUSION: This study expands the spectrum of genetic variants for arRP in Pakistani families.
RESUMO
OBJECTIVE: To evaluate the existing practices of obtaining and documenting informed consent in cases of oral and maxillofacial surgery. METHODS: The cross-sectional study was conducted from April to June 2017 at the Oral and Maxillofacial Surgery departments of five teaching hospitals of Rawalpindi and Islamabad, Pakistan, and comprised patients who underwent surgery under general anaesthesia. Data was collected using questionnaire-based interviews a day after the surgery in each case regarding multiple aspects of the informed consent practices. Data was analysed using SPSS 21. RESULTS: Of the 100 patients, 58(58%) were males and 42(42%) were females, while 81(81%) were adults aged >18 years. In 42(42%) cases, the consent document was signed by the patient, and by a relative in 38(38%) cases. In the remaining 20(20%) cases, only verbal consent was taken. In 54(54%) cases nursing staff and in 46(46%) cases residents took the consent. Most patients were informed about nature of their disease 87(87%), proposed treatment 86(86%) and type of anaesthesia 100(100%). Fewer patients were informed about any alternative treatments 38(38%), and possible complications of the surgery 51(51%) or anaesthesia 26(26%). Overall, 44(44%) patients did not fully understand the written information, and 23(23%) said they were encouraged to ask questions. CONCLUSIONS: The quality of informed consent practices was found to be sub-optimal in oral and maxillofacial surgery setups.

This study presents the assessment of the risks incidental to the growth of the common tropical grass species Chloris barbata Sw. (swollen windmill grass) on road margins contaminated with Pb and Cd. Pot experiments were first carried out to quantify the Pb and Cd accumulation potential of the plant species in various plant parts as a function of the metal concentration in soil. C. barbata was found to be a hyperaccumulator for Cd (BCF>1, for aerial parts) and an excluder of Pb (BCF<1, for aerial parts). As the plant was found to accumulate Pb in its roots with TF<1, it can be considered a phytostabilizer of Pb. The mathematical relationship developed between soil concentrations of Pb and Cd and their corresponding concentrations in aerial parts were used in combination with the concentrations of these heavy metals reported in roadside soils to obtain estimates of their accumulation in the forage and consequently in the animal organs. Risk to the consumers of offal was estimated. It was found that the consumption of kidney meat was riskier than the consumption of liver meat. Furthermore, it was seen that despite the nearly two order less concentrations of Cd in roadside soils compared to Pb, it was posing a higher risk. For the median concentrations of Pb reported in roadside soils and cattle feeding exclusively on C. barbata growing on roadside soils, the HQ exceeded 1 for weekly consumption of kidney meat above 650 g. For median Cd concentrations, consumption of kidney meat above 230 g/week resulted in HQ>1. The scenario considered for risk assessment is significant for India, where stray grazing of cattle on road margins is common and offal offers a cheap source of animal protein for the economically poor.

World over, the instances where polluters are made to pay for the damages they have caused to the environment are on the rise. If more than one party is found responsible for pollution, our analyses of statutes of different countries, covering more than 57% of the world population and more than 45% of its land area, showed that liability is to be allocated among the involved parties on an equitable basis, often decided by the courts. Analyses of a number of court cases showed that the factors considered for allocation in such cases may be classified into two, technical and non-technical. It was also found that the legal liability of pollution was different from the technical liability in many cases due to the influence of non-technical factors that were very specific to the case. These non-technical factors often do not fall under the investigation purview of an environmental forensic expert who carries out technical investigations to find the responsible parties. Based on the analysis, it is suggested that the liability allocation be a two-stage process; the first stage being technical liability allocation done by the forensic expert and the second stage the final (legal) allocation by the court. It is also suggested that clear guidelines be prepared for technical liability allocation. There was also a felt need to quantify remediability to make the remediation liability allocation easier.

PURPOSE OF REVIEW: Craniomaxillofacial (CMF) trauma is a common cause of global morbidity and mortality. Although in high resource settings the management of CMF trauma has improved substantially over the past several decades with internal rigid fixation technology; these advancements have remained economically unviable and have not yet reached low and middle-income countries (LMICs) en masse. The purpose of this review is to discuss the current management of CMF injuries in low-resource settings. RECENT FINDINGS: Trauma injuries remain a global epidemic with head and neck injuries among the most common. CMF trauma injuries largely occur in LMICs, with motor vehicle trauma being a common cause. Patients present in a delayed fashion which increases complications. Diagnostic methods are often limited to plain radiographs as computed tomography is not always available. In low-resource settings, CMF trauma continues to be treated primarily by closed reduction, maxillomandibular fixation, and transosseous wiring, yielding acceptable results through affordable methods. With the advent of less expensive plating systems, internal fixation with plates and screws are gradually finding their place in the management of facial trauma in low-resource settings. A shortage of CMF surgeons in LMICs is a recognized problem and is being addressed by targeted curricula. SUMMARY: CMF trauma is a major cause of morbidity and mortality globally that remains poorly addressed. Currently, conventional methods of treating CMF trauma in low-resource settings have evolved to meet resource constraints. The education of CMF surgeons remains a key leverage point in improving CMF trauma care globally.

OBJECTIVE: To evaluate the novel locally manufactured osteosynthetic titanium bone mini plates used for mandibular fracture fixation, and to compare it with an international brand to have an alternative to expensive plates. METHODS: The study was conducted at National University of Science and Technology from Jan 2013 to June 2013. Local and German brands of osteosynthetic titanium bone mini plates were studied electrochemically through Tafel extrapolation curves using Gamry® electrochemical framework in modified simulated body fluid prepared with pH 7.4 at 37OC. For bacterial adhesion, staphylococcus aureus bacterial culture of 50 ïl was used with an OD600 of 1.0 corresponding to approximately 1.79×109 cells ml-1. Data was analysed using SPSS 20.. RESULTS: Corrosion resistance behaviour of local and German plates was not significantly different (p>0.05), but in case of bacterial adhesion the local plates showed significantly low adhesion compared to the imported material (p<0.05). Overall, the biocompatible properties of local plates met international brand qualities. CONCLUSIONS: Electrochemical corrosion and bacterial adhesion of local osteosynthetic maxillofacial bone plates matched the quality of an international brand.

PURPOSE: Genomic testing is recognized in national guidelines as essential to guide appropriate therapy selection in metastatic colorectal cancer. Previous studies report adherence to testing guidelines is suboptimal, but current testing rates have not been assessed. This study reports testing rates in metastatic colon cancer (mCC) for guideline-recommended biomarkers in a US-based population. MATERIALS AND METHODS: A retrospective review of data extracted from electronic medical records was performed to identify patients with pathologically confirmed mCC and describe patterns of guideline-aligned biomarker testing. Data were extracted from the electronic health records of 1,497 patients treated at 23 practices across the United States. Both community and academic centers were represented. RESULTS: A total of 1,497 patients with mCC diagnosed between January 1, 2013 and December 31, 2017 were identified. Guideline-aligned biomarker testing rates for RAS, BRAF, and microsatellite instability/mismatch repair deficiency over this study period were 41%, 43%, and 51%, respectively. Patients were more likely to have guideline-aligned testing for RAS and BRAF if they were treated at an academic center, were diagnosed with de novo metastatic disease, and were female. In addition, patients < 65 years of age were more likely to have guideline-aligned RAS testing. Of the 177 patients (12% of cohort) who received anti-epidermal growth factor receptor therapy, only 50 (28%) had complete guideline-aligned biomarker testing. CONCLUSION: Despite guideline recommendations and significant therapeutic implications, overall biomarker testing rates in mCC remain suboptimal. Adherence to guideline-recommended biomarker testing would potentially reduce exposure to expensive and ineffective therapies, resulting in improved patient outcomes.
RESUMO
A 45-year-old female without any past or family history of psychiatric illness presented to the emergency department with complaints of abnormal behavior, irrelevant talking, restlessness, episodic crying, and decreased sleep of 2-day duration. On detailed interview, the attendants gave a history of an intermittent headache of 6-month duration and hearing impairment of 4-month duration. On investigation, her cerebrospinal fluid was reactive, and brucella titers were positive. She received appropriate treatment for 6 months and a short course of antipsychotics. Her symptoms settled, but she had persistent hearing loss. Psychosis as well as hearing loss is a very rare presentation of brucellosis. The case highlights the importance of considering neurobrucellosis as a differential diagnosis in patients with any unexplained neuropsychiatric symptoms such as acute psychosis or hearing loss.
RESUMO
Obstructive sleep apnea syndrome (OSAS), commonly associated with mandibular micrognathia, is a serious condition that can lead to various devastating cardiovascular and neurocognitive consequences. Patients of OSAS with micrognathia present with many functional and esthetic problems. Therefore, comprehensive management of these patients requires multiple surgeries and frequent follow-up. Several surgical and non-surgical treatment options have been proposed for the treatment of OSAS. Distraction osteogenesis (DO) in maxillofacial region, although a newer treatment modality, is being increasingly favoured by many surgeons because of its many advantages over other treatment methods. We present comprehensive management of a case of OSAS associated with post temporomandibular joint ankylosis severe micrognathia. Various surgical treatment methods including DO and conventional orthognathic surgical procedures were employed in management of this patient of obstructive sleep apnea. Both functional and esthetic complaints of the patient were addressed, and we achieved exceptional results at the end of treatment.

BACKGROUND: Trauma is a significant contributor to global disease, and low-income countries disproportionately shoulder this burden. Education and training are critical components in the effort to address the surgical workforce shortage. Educators can tailor training to a diverse background of health professionals in low-resource settings using competency-based curricula. We present a process for the development of a competency-based curriculum for low-resource settings in the context of craniomaxillofacial (CMF) trauma education. METHODS: CMF trauma surgeons representing 7 low-, middle-, and high-income countries conducted a standardized educational curriculum development program. Patient problems related to facial injuries were identified and ranked from highest to lowest morbidity. Higher morbidity problems were categorized into 4 modules with agreed upon competencies. Methods of delivery (lectures, case discussions, and practical exercises) were selected to optimize learning of each competency. RESULTS: A facial injuries educational curriculum (1.5 days event) was tailored to health professionals with diverse training backgrounds who care for CMF trauma patients in low-resource settings. A backward planned, competency-based curriculum was organized into four modules titled: acute (emergent), eye (periorbital injuries and sight preserving measures), mouth (dental injuries and fracture care), and soft tissue injury treatments. Four courses have been completed with pre- and post-course assessments completed. CONCLUSIONS: Surgeons and educators from a diverse geographic background found the backward planning curriculum development method effective in creating a competency-based facial injuries (trauma) course for health professionals in low-resource settings, where contextual aspects of shortages of surgical capacity, equipment, and emergency transportation must be considered.

Beautiful smile is a booster to person's confidence. Gummy smile is a term used for excessive gingival display (EGD). Its etiology is multifactorial. Bone vertical maxillary excess (VME) is one of the cause of EGD. In this case series, lip repositioning was performed to treat mild to moderate degree of gingival display ( 2 to 8 mm) due to VME. Lip repositioning is simple, promising, meticulous and comparatively cheap alternative technique for treating gummy smile.

OBJECTIVE: The objective of this study was to describe the demographic features, clinical presentation, and management and outcome of fifty cases of nonalcoholic Wernicke's encephalopathy from a tertiary care hospital of a region with reported incidence of thiamine deficiency disorders. MATERIALS AND METHODS: In a retrospective study, fifty adult cases of Wernicke's encephalopathy were analyzed. The diagnosis of Wernicke's encephalopathy was made according to the European federation of neurological societies guidelines 2010. Response to thiamine replacement and associated brain magnetic resonance imaging (MRI) findings were also considered as supportive evidence. RESULTS: The mean age of patients was 50.38 years with 20 males and 30 females. The most common clinical manifestations were alteration in sensorium in 30 (60%), ataxia in 18 (36%), memory impairment in 15 (30%), nystagmus in 35 (70%), ophthalmoparesis in 11 (22%), and seizures in 4 (8%). A total of 42 patients had a history of recurrent vomiting. All patients had polished rice as their staple diet. Thirty-five patients had associated polyneuropathy and 15 had a gastrointestinal disorder. Twenty patients underwent MRI which showed both typical and atypical lesions. Majority of patients showed partial or complete response to intravenous thiamine. On discharge, the most common residual symptoms were lower limb weakness, ataxia, and memory impairment. CONCLUSION: The study shows high incidence of nonalcoholic Wernicke's encephalopathy in the region with predominant causative factor being a thiamine deficient diet. Recurrent vomiting can be a prominent early symptom of thiamine deficiency and its recognition can help in the early diagnosis of Wernicke's encephalopathy and related thiamine deficiency disorders. Thiamine fortification of food should be done in areas with reported incidence of thiamine deficiency disorders.
RESUMO
BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is a chronic psycho-physiological disorder. It is considered to be the most common functional gastrointestinal disorder, and about 50-90% of IBS patients have associated psychiatric co-morbidity. We aimed to study psychiatric co-morbidities in patients with IBS visiting a tertiary care center. METHODS: This was a cross-sectional case-control study conducted over a duration of one and a half years from January 2014 to July 2015. Patients were selected from the out-patient department of gastroenterology. About 160 patients with IBS who fulfilled the inclusion criteria and who gave written informed consent were selected as study cases. The healthy attendants of cases were selected as controls. A total of 200 controls were selected. Rome-III criteria were used to diagnose IBS. For diagnosing psychiatric disorders, we used the Mini International Neuropsychiatric Interview Schedule Plus. RESULTS: Mean age of our cases and controls was 39.7 ± 11.4 and 37.7 ± 9.6 years, respectively. Females outnumbered males in our cases as well as their controls by a ratio of 2:1 approximately. Psychiatric disorders were seen in 84.4% of IBS patients as compared to 41.5% in controls. Major psychiatric disorders seen in our patients were generalized anxiety disorders (30.0%) and depression (28.0%). CONCLUSIONS: The majority of patients with IBS who present to a tertiary care center have co-morbid psychiatric disorders. We need to screen these patients for such co-morbidities and develop a holistic approach for better outcome in such cases.
