Study of utilization of antimicrobial drugs and its resistance pattern in patients with septicemia at a tertiary care hospital

Background: Many types of bacteria can produce septicemia. The most common infections that lead to septicemia are urinary tract infections, pneumonia, nephritis and abdominal infections. Methods: The study aims to assess the pattern of antimicrobial drugs used in septicemia and to assess the etiological organisms and their drug sensitivity and resistance pattern. Study participants admitted to tertiary health care centre and who are having septicemia were included in this prospective observational study. Blood culture, bronchial secretions were subjected to microbiological analysis. The etiological organisms, their drug sensitivity and resistance pattern and the outcome of drug therapy were recorded. The clinical course of the study participants was monitored till cure either the resolution of pneumonia. Qualitative data were analyzed using the chi-square test or Fischer's exact test and quantitative data using the independent t test. Results: Mean duration of hospital stay in all patients 13.22±0.45 days and in resistance cases it was found 19.22±0.45 days. Mean duration of ICU stay in all patients was 4.34±0.45 days and in resistant cases mean duration of ICU stay was 8.18±0.45 days. Clinical outcome in overall admitted patients recovered was 97 patients (80.83%) death was 16 patients (13.33%). Clinical outcome in resistant patients recovered 16 patients (13.33%) and death 26 patients (21.66%). Conclusions: The organisms had a varied sensitivity and resistance pattern. The clinical outcome was multifactorial.

Evaluation of antimicrobial activity of Lactobacillus acidophilus and Lactobacillus rhamnosus against clinically isolated Klebsiella pneumoniae: an in vitro study

Background: Klebsiella pneumoniae are Gram-negative opportunistic pathogen, belonging to the family Enterobacteriaceae that can cause severe nosocomial infections particularly in immuno-compromised individuals. They exhibit co-resistance to multiple antibiotics which emphasize the need for non-antibiotic therapies. The goal of the presented study was to investigate the antimicrobial ability of probiotic Lactobacilli on clinical isolates of K. pneumoniae. Methods: In this cross-sectional study, antimicrobial activities of probiotic L. acidophilus and L. rhamnosus on K. pneumoniae were evaluated by Agar overlay interference technique. Clear zone around Lactobacilli were taken as positive inhibition. Antibiotic susceptibility profiles of K. pneumoniae were determined by Kirby-Bauer disk diffusion method, analyzed using interpretive standards of CLSI M100-S33 and categorized into MDR, XDR and Non MDR groups. Statistical analysis was done using descriptive statistics such as mean and standard error and inferential statistics such as ANOVA single factor. Results: K. pneumoniae exhibited positive inhibition with both the probiotic strain. On comparing the zone of inhibition of L. acidophilus and L. rhamnosus (both treated-pH adjusted and untreated), L. acidophilus had greater zone of inhibition against K. pneumoniae but concluded that statistically the values are insignificant (p>0.05). Based on antibiotic susceptibility pattern of K. pneumoniae, 63% of isolates were XDR, 3% were MDR and 34% were Non MDR Conclusions: It can be concluded that L. acidophilus and L. rhamnosus had significant inhibitory effect against K. pneumoniae in vitro and should be further studied for their human health benefit.

Artificial intelligence–based stratification of demographic, ocular surface high-risk factors in progression of keratoconus

Purpose: The purpose of this study was to identify and analyze the clinical and ocular surface risk factors influencing the progression of keratoconus (KC) using an artificial intelligence (AI) model. Methods: This was a prospective analysis in which 450 KC patients were included. We used the random forest (RF) classifier model from our previous study (which evaluated longitudinal changes in tomographic parameters to predict “progression” and “no progression”) to classify these patients. Clinical and ocular surface risk factors were determined through a questionnaire, which included presence of eye rubbing, duration of indoor activity, usage of lubricants and immunomodulator topical medications, duration of computer use, hormonal disturbances, use of hand sanitizers, immunoglobulin E (IgE), and vitamins D and B12 from blood investigations. An AI model was then built to assess whether these risk factors were linked to the future progression versus no progression of KC. The area under the curve (AUC) and other metrics were evaluated. Results: The tomographic AI model classified 322 eyes as progression and 128 eyes as no progression. Also, 76% of the cases that were classified as progression (from tomographic changes) were correctly predicted as progression and 67% of cases that were classified as no progression were predicted as no progression based on clinical risk factors at the first visit. IgE had the highest information gain, followed by presence of systemic allergies, vitamin D, and eye rubbing. The clinical risk factors AI model achieved an AUC of 0.812. Conclusion: This study demonstrated the importance of using AI for risk stratification and profiling of patients based on clinical risk factors, which could impact the progression in KC eyes and help manage them better

Type 1–type 2 interferon imbalance in dry eye disease

Purpose: Dry eye disease (DED) is characterized by altered ocular surface proinflammatory and antiinflammatory factors. Interferons (IFNs) are a class of pleiotropic cytokines well known for their antimicrobial, inflammatory, and immunomodulatory roles. Hence, this study investigates the ocular surface expression of different types of IFNs in patients with DED. Methods: The cross?sectional, observational study included patients with DED and normal subjects. Conjunctival impression cytology (CIC) samples were obtained from the study subjects (controls, n = 7; DED, n = 8). The mRNA expression levels of type 1 IFN (IFN?, IFN?), type 2 IFN (IFN?), and type 3 IFN (IFN?1, IFN?2, IFN?3) were measured by quantitative PCR (polymerase chain reaction) in CIC samples. IFN? and IFN? expression under hyperosmotic stress was also studied in human corneal epithelial cells (HCECs) in vitro. Results: The mRNA expression levels of IFN? and IFN? were significantly lower and that of IFN? was significantly higher in DED patients compared to healthy controls. The mRNA levels of IFN?, IFN?, and IFN? were significantly lower compared to IFN? in DED patients. An inverse association between tonicity?responsive enhancer?binding protein (TonEBP; hyperosmotic stress maker) and IFN? or IFN? expression and a positive association between TonEBP and IFN? expression was observed in CIC samples. The expression of IFN? was lower than IFN? in HCECs undergoing hyperosmotic stress compared to HCECs without the stress. Conclusion: The presence of an imbalance between type 1 and type 2 IFNs in DED patients suggests newer pathogenic processes in DED, plausible ocular surface infection susceptibility in DED patients, and potential therapeutic targets in the management of DED

Role of artificial intelligence in determining factors impacting patients’ refractive surgery decisions

Purpose: To create a predictive model using artificial intelligence (AI) and assess if available data from patients’ registration records can help in predicting definitive endpoints such as the probability of patients signing up for refractive surgery. Methods: This was a retrospective analysis. Electronic health records data of 423 patients presenting to the refractive surgery department were incorporated into models using multivariable logistic regression, decision trees classifier, and random forest (RF). Mean area under the receiver operating characteristic curve (ROC?AUC), sensitivity (Se), specificity (Sp), classification accuracy, precision, recall, and F1?score were calculated for each model to evaluate performance. Results: The RF classifier provided the best output among the various models, and the top variables identified in this study by the RF classifier excluding income were insurance, time spent in the clinic, age, occupation, residence, source of referral, and so on. About 93% of the cases that did undergo refractive surgery were correctly predicted as having undergone refractive surgery. The AI model achieved an ROC?AUC of 0.945 with an Se of 88% and Sp of 92.5%. Conclusion: This study demonstrated the importance of stratification and identifying various factors using an AI model which could impact patients’ decisions while selecting a refractive surgery. Eye centers can build specialized prediction profiles across disease categories and may allow for the identification of prospective obstacles in the patient’s decision?making process, as well as strategies for dealing with them.

Left Ventricular Geometry and Function in Patients with Gray Zone Hypertension

Background: Hypertension is considered as the silent killer of human because the hypertensive patient may be not aware that he has hypertension and death can occur at any time without the reason being known. We aim to study the effect of gray zone hypertension [SBP from 120-139] and or [DBP from 80-89] which was classified as prehypertension under JNC-7 on the structure, geometry, and operation of the left ventricle using echocardiography Methods: This study included 100 patients who asymptomatic apparent healthy subjects visited cardiology outpatient department (OPD) for routine checkup. Patients were grouped into two equal groups: Group A whose blood pressure was in the gray zone hypertension [SBP from 120-139] and or [DBP from 80-89], and group B with SBP <120 mmHg & DBP <80 mmHg. Results: The two groups being studied were statistically significant different as regard LV geometrical pattern (p=0.028). They were also statistically significant in LV geometrical pattern between the males and females (p<0.05). The two groups were statistically significant different regarding GLS (p =0.001). Conclusions: Gray zone hypertension affects ventricular diastolic function and LV geometry, although systolic function was normal; GLS showed that subclinical LV dysfunction can occur.

Associação entre eficiência alimentar e ganho em acabamento de carcaça de bovinos da raça Nelore / Association between feed efficiency and carcass finishinging gain of Nellore cattle

Objetivou-se estimar a associação fenotípica entre a eficiência alimentar e o ganho em acabamento de carcaça de touros jovens da raça Nelore. Utilizaram-se informações de 98 touros jovens da raça Nelore, participantes de duas provas de eficiência alimentar que empregaram o sistema de cochos eletrônicos Growsafe®, as quais foram realizadas nos anos de 2015 e 2016, na fazenda Capim Branco, da Universidade Federal de Uberlândia. As provas de eficiência alimentar tiveram duração de 91 dias, sendo 21 dias de adaptação e 70 dias de avaliação. Os animais apresentavam idade média ao início e ao término do confinamento de 19,98 e 22,16 meses e peso inicial e final médio de 428,17 e 542,27kg, respectivamente. Verificou-se que os animais mais eficientes depositaram menos gordura, e os animais menos eficientes depositaram mais gordura durante o período de avaliação em confinamento. Observou-se que há uma associação fenotípica de baixa magnitude (0,29) entre o consumo alimentar residual (CAR) e o ganho em acabamento de carcaça (GACAB). Assim, pode-se inferir que, ao serem selecionados menores valores de CAR, haverá alguma interferência negativa em GACAB. Concluiu-se que animais mais eficientes (CAR negativo) podem apresentar menor deposição de gordura subcutânea, influenciando na qualidade de carcaça de bovinos da raça Nelore.(AU)

This study aimed to estimate the phenotypic association between feed efficiency and gain in carcass finishing of young Nelore bulls. Information from 98 young Nelore bulls participating in two feed efficiency tests using the Growsafe® electronic trough system, carried out in the years 2015 and 2016, at the Capim Branco farm of the Universidade Federal de Uberlândia was used .The feed efficiency tests lasted for 91 days, with 21 days of adaptation and 70 days of evaluation. The animals had a mean age at the beginning and end of the confinement of 19.98 and 22.16 months, and mean weight initial and end of 428.17 and 542.27kg, respectively. It was verified that most efficient animals deposited less fat, and the efficient animals deposited more fat during the evaluation period at the confinement. It was observed that there is a low magnitude phenotypic association (0.29) between the residual feed intake (RFI) and the gain in carcass finishing (GACAB). Thus, it can be inferred that by selecting lower values of residual feed intake there will be some negative interference in GACAB. It was concluded that the most efficient animals (negative RFI) may present lower deposition of subcutaneous fat, influencing the carcass quality of Nelore cattle.(AU)

Immunophenotyping, plasticity tests and nanotagging of stem cells derived from adipose tissue of wild rodent agouti (Dasyprocta prymnolopha) / Imunofenotipagem, testes de plasticidade e marcação com nanocristais de céluas-tronco derivadas de tecido adiposo em cutias

There is a growing interest in the study of unspecialized mesenchymal stem cells, for there are still some discussions about their in vitro behavior. Regenerative medicine is a science undergoing improvement which develops treatments as cell therapy using somatic stem cells. In several studies, adipose tissue is presented as a source of multipotent adult cells that has several advantages over other tissue sources. This study aimed to characterize and evaluate the tagging of mesenchymal stem cells from the agoutis adipose tissue (Dasyprocta prymonolopha), with fluorescent intracytoplasmic nanocrystals. Fibroblast cells were observed, plastic adherent, with extended self-renewal, ability to form colonies, multipotency by differentiation into three lineages, population CD90 + and CD45 - expression, which issued high red fluorescence after the tagging with fluorescent nanocrystals by different paths and cryopreserved for future use. It is possible to conclude that mesenchymal stem cells from agouti adipose tissue have biological characteristics and in vitro behavior that demonstrate its potential for use in clinical tests.(AU)

Aim: The aim of this study was to evaluate the oral health status in 6 to 10-year-old asthmatic children receiving bronchodilator (salbutamol, salmeterol, etc.) through inhaler and compare them with nonasthmatic healthy children. Settings and Design: The present study was carried out at pediatric and pedodontic department and neighboring government school. It was an observational and case–control study. Statistical Analysis: All data were analyzed using SPSS 20.0 software program and presented as mean ± standard error of mean. Chi-square test was used for the categorical data between groups. Numerical data were analyzed by Mann–Whitney U-test and t-test. Kruskal–Wallis test was performed for comparisons of median value of decayed, missing, filled surface and Decayed, Missing, Filled Surface (dmfs and DMFS) for different variables within asthmatic group. Mann–Whitney U-test for multiple comparisons and P value was adjusted according to Bonferroni correction. Negative binomial analysis was used to calculate adjusted dmfs and DMFS, and univariate analysis of variance was used for adjusted mean plaque and gingival index. Materials and Methods: The study group composed of 70 asthmatic and 70 nonasthmatic children with the same age and social background aged between 6 and 10 years old. Oral health status was assessed using caries, plaque, and gingival index. Dental caries examination was done using the WHO criteria (1997), plaque index by Silness and Loe in 1964 and gingival health by Loe and Silness in 1963. Results: The children in the asthmatic group had significantly higher caries prevalence, severity of dental plaque, and gingivitis compared with the nonasthmatic group. Plaque accumulation and gingivitis increased significantly as severity and duration of asthma increased. Conclusions: Bronchial asthma had an overall deleterious effect on caries prevalence and severity, plaque, and gingivitis on primary and permanent teeth.

Índice de normalidade da distância atlantoaxial dorsal em cães / Normal index of dorsal atlantoaxial distance in dogs

Foram utilizados 30 cães neurologicamente saudáveis e realizadas radiografias da coluna cervical, sendo mensurada a menor distância atlantoaxial dorsal e outros parâmetros anatômicos vertebrais. Esses dados foram avaliados por meio do coeficiente de correlação de Pearson. Após detecção do melhor parâmetro de correlação, utilizou-se a fórmula de coeficiente de correlação dimensional (CCD). Na segunda etapa desta pesquisa, foram utilizadas imagens radiográficas de 33 cães com subluxação atlantoaxial (SAA) e aplicou-se a fórmula CCD. Todas as imagens atlantoaxiais normais e subluxadas foram distribuídas aleatoriamente e submetidas à análise subjetiva. Observou-se que o parâmetro anatômico de maior correlação foi o comprimento do processo espinhoso do áxis, obtendo-se valor de índice médio de 0,056 e desvio-padrão de 0,019. O valor de índice médio obtido em cães com SAA foi de 0,287, e o desvio-padrão de 0,123. A análise subjetiva revelou acerto de 88,89% a 95,24%, enquanto a avaliação por meio da fórmula CCD demonstrou ser 100% eficiente no diagnóstico da SAA. Sugeriu-se a utilização da fórmula CCD para obtenção do índice de normalidade da distância atlantoaxial com valor de normalidade médio de 0,056 e limite máximo de 0,098, sendo esse índice eficaz no diagnóstico da subluxação entre o atlas e o áxis.(AU)

Thirty healthy dogs had their cervical spines radiographed, and the dorsal atlantoaxial distance and others vertebral anatomical parameters were measured. These data were assessed using the Pearson correlation coefficient. After detection of the best correlation parameter, we used the dimensional correlation coefficient of formula (CCD). In the second stage of the study, radiographs of the 33 dogs with atlantoaxial subluxation (SAA) were used. In each radiographic image, the CCD formula was applied. All normal and subluxation radiographic images were randomized, and submitted to subjective analysis. It was observed that the anatomical parameter with the highest correlation is the length of the spinous process of the axis, obtaining a mean value of 0.056 index and 0.019 standard deviation. Index mean value obtained in dogs with the disease of 0.287 and standard deviation of 0.123. The subjective analysis revealed 88.89% to 95.24% agreement, while the result obtained by the CCD formula was shown to be 100% effective in the diagnosis of SAA. We suggest the use of the CCD formula to obtain the index of normality of the atlantoaxial distance with a mean value of 0.056 and maximum of 0.098, and it is concluded that the index is highly effective in the diagnosis of subluxation between the atlas and the axis.(AU)

Consequences of intraoperative spinal cord manipulation in dogs with thoracolumbar intervertebral disc extrusion / Consequências da manipulação medular intraoperatória em cães com extrusão intervertebral de disco toracolombar

The objective of the present study was to evaluate if extradural contact during hemilaminectomy would cause neurological deterioration in the early and/or late postoperative period in dogs with intervertebral disc extrusion. Nineteen dogs with thoracolumbar intervertebral disc extrusion underwent hemilaminectomy for spinal cord decompression and removal of extruded disc material. Meningeal contacts during surgery were quantified. Paraplegia (with nociception) and paraparesis were observed in 11/19 and 8/19 of dogs, respectively, before surgery. At the end of our study, only two (2/19) had paraplegia and one (1/19), paraparesis. There were more extradural contacts when extruded intervertebral disc material was at a ventrolateral position. Extradural contacts during surgery had no influence on neurological progression nor on time to recovery of motor function. Immediately (24 and 48 hours) after surgery, 13/19 dogs had the same neurological stage before surgery. At 7 and 90 days, 13/19 and 17/19 dogs, respectively, showed neurological improvement, compared with their preoperative stage. There was no influence of the number of extradural contacts on neurological recovery. These findings indicate that a careful inspection of the vertebral canal for removal of as much extruded disc material as possible does not cause neurologic deterioration.(AU)

O presente trabalho teve como objetivo avaliar se contatos extradurais durante hemilaminectomia em cães com extrusão de disco intervertebral causariam piora neurológica no pós-operatório imadiato e/ou tardio. Dezenove cães com extrusão toracolombar de disco intervertebral foram submetidos à hemilaminectomia para descompressão medular e remoção do material extruso. Durante o procedimento cirúrgico, os contatos meningomedulares foram quantificados. Antes da cirurgia, 11/19 cães apresentavam paraplegia (com nocicepção) e 8/19 cães, paraparesia. Ao fim do estudo, apenas dois cães (2/19) mostravam paraplegia com dor profunda e um (1/19), paraparesia. Observou-se maior quantidade de contatos extradurais quando o material discal extruso encontrava-se em posição ventrolateral. Os contatos extradurais não mostraram influência estatística na evolução neurológica dos animais, bem como no tempo de recuperação das funções motora. Vinte e quatro e 48 horas após a cirurgia, 13/19 cães apresentavam o mesmo grau neurológico de antes da cirurgia. Após sete e 90 dias de pós-operatório, 13/19 e 17/19 demonstraram melhora neurológica em comparação com o pré-operatório, respectivamente. A quantidade de contatos extradurais não influenciou na recuperação neurológica dos cães. Esses achados indicam que uma inspeção minuciosa do canal vertebral pode ser recomendada, a fim de remover o máximo de material discal extruso, evitando-se piora neurológica por compressão medular.(AU)

Desenvolvimento e avaliação de equipamento de tração, para redução de fraturas de ossos longos de cães / Development and evaluation of a traction device for reducing long bone fractures in dogs

Fraturas costumam ocorrer com encavalgamento das extremidades ósseas, dificultando, assim, sua redução. Esta pesquisa teve como objetivo desenvolver um equipamento de tração esquelética a ser utilizado em caninos acometidos de fraturas de ossos longos. Foram utilizados 21 cães de raças variadas, pesando entre dois e 27kg, com idade entre dois meses e 11 anos, com fraturas diafisárias ou metafisárias ocorridas entre três e 24 dias. Enquanto a fixação do corpo do paciente à mesa foi efetuada com cintas de náilon, a força de tração aplicada ao longo do eixo ósseo do membro fraturado foi realizada mediante cintas de náilon ou pinos transfixados e estribos (sendo os pinos implantados na epífise distal do osso fraturado), com a força de tração medida por um dinamômetro, não sendo aplicada carga maior que 25kg. Em todos os casos, a força de tração iniciava com o valor de cinco quilogramas, exceto em animais com peso inferior a esta, a qual começava com carga equivalente a esse peso; e em todos, se necessário, era aumentada a cada cinco minutos para se manter tração igual ao peso ou aos valores que oscilavam do seu peso até cinco quilogramas, dependendo do tamanho do animal, até se atingir a tração necessária para se proceder à redução. Para essa progressão de distensão, o equipamento possuía haste rosqueada de 25mm de diâmetro, uma porca com sistema timão e cilindro deslizante por fora da haste, este conectado ao animal por uma corrente, e o dinamômetro. Todos os animais tiveram as fraturas reduzidas sem haver perda óssea, o que evidencia que o aparelho se mostrou eficiente tanto na redução como na manutenção da redução da fratura, e eles não apresentaram, no pós-operatório, sinais de prejuízos neurológicos, vasculares, cutâneos e articulares. O distensor ósseo aqui desenvolvido tem como características: ser de simples confecção, ter baixo custo, não gerar danos ao paciente e facilitar a redução dos fragmentos tanto em fraturas recentes quanto em antigas.(AU)

Fractures usually occur with overriding of bone fragments, thus hindering fracture reduction. The aim of this research was to develop and test a skeletal traction device for use in dogs with long bone fractures. Twenty-one dogs were included, regardless of breed or gender, weighing between two and 27kg, and between two months and 11 years of age, with metaphyseal or diaphyseal fractures that had occurred between three and 24 days prior to intervention. While fixation of the patient's body to the table was performed using nylon straps, the traction force applied along the bone axis of the fractured limb was performed using nylon straps or transfixed pins and stirrups (with the pins implanted in the distal epiphysis of the fractured bone). Tensile strength was measured by a dynamometer, and the maximum load applied was no greater than 25kg. In all cases, the distraction force began at five kilograms except in dogs below this weight, where the starting load was equivalent to the weight of the animal. If necessary, in all dogs, force was increased every five minutes to maintain equal traction to the dog's weight or values which ranged from the dog's weight to five kilograms depending on the size of the animal, until the necessary traction for reduction was obtained. For this progression of distension, the equipment had a 25-milimeter-diameter threaded rod, a nut with a rudder system and sliding cylinder outside the rod, which connected to the dog via a chain and the dynamometer. Fracture reduction was achieved in all dogs without bone loss, and the device was shown to be efficient in both allowing and maintaining fracture reduction, with no neurologic, vascular, cutaneous, or articular damage. The developed bone distractor has the following characteristics: simple to construct, low cost, does not harm the patient, and facilitates reduction of the fragments in recent and old fractures.(AU)

Aparência tomográfica dos discos intervertebrais mineralizados em cães da raça Dachshund Miniatura / Tomographic appearance of calcified intervertebral discs in miniature dachshund

Objetivou-se com este trabalho descrever os aspectos de tomografia computadorizada de discos intervertebrais de cães da raça Dachshund com um ano de idade, assim como quantificar, qualificar e localizar a mineralização nos componentes do DIV e no espaço intervertebral da coluna vertebral. Dez cães dessa raça, com um ano de idade, foram submetidos à tomografia computadorizada (TC). Nas imagens de reconstrução sagital dos animais, procedeu-se à identificação de sete DIV em cada animal, entre as vértebras T9 e L3, totalizando a análise de 70 DIV. Entre os DIV mineralizados, a presença da alteração foi determinada quanto à localização no núcleo pulposo (NP), no anel fibroso (AF) e em AF/NP. Dos 70 DIV avaliados, 45 foram considerados como mineralizados. Entre os classificados como mineralizados, 20% (9/45), 17,8% (8/45) e 62,2% (28/45) estavam localizados nas regiões do NP, AF e AF/NP, respectivamente. A mineralização encontrada neste estudo esteve caracterizada por aumento de atenuação radiográfica com densidade mineral na topografia do DIV, havendo variações da localização e da radiodensidade de área calcificada entre animais e DIV no mesmo indivíduo. As alterações relativas à mineralização dos DIV podem ser classificadas tomograficamente quanto à localização da alteração no disco em AF, NP e AF/NP.(AU)

The objective was to describe CT imaging of calcified IVD in one-year-old Dachshunds, as well as describe the location in the soft tissue structures that make up the IVD. Ten one-year-old dogs underwent computed tomography (CT). In sagittal reconstruction images of animals, the identification of 70 IVD present in the spaces between L3 - T9 were performed. Among calcified IVDs, the presence of the change was determined as the location in the nucleus pulposus (NP), annulus fibrosus (AF) and both. Of a total of 70 evaluated IVDs, 45 were found to calcified and 25 not calcified. Among calcified discs, location was determined in nine (20%) in NP, eight discs (17.77%) in AF and 28 (62, 23%) NP & AF. Calcification in this study was characterized by increased radiographic attenuation mineral density in the IVD topography. There is variation in the location and radiodensity of calcified areas between animals and IVD in the same individual. Changes related to IVD calcification can be classified as tomographic location in AF, NP and NP & AF.(AU)

Prepucial Epstein Pearls: Revisited

Milia are minute follicular epidermal cysts, commonly found over the cheeks, nose, upper lip, forehead, and rarely over the areolae and genitalia.Prepucial milia (Prepucial Epstein pearl), are pearly white papules, 1-2mm in size found on the prepuce or shaft of the penis in a male new born. They are benign in nature and almost always disappear within a few weeks. Prepucial milia evoke a lot of concern and anxiety to the parents. Physician and child healthcare providers should be aware of this condition to avoid unnecessary intervention.

Profiling of Pro-Inflammatory Cytokines in Radiation Induced Oral Mucositis (RIOM) among Indian patients

Radiation-induced oral mucositis (RIOM) is aimed at evaluating the expression of NF-κß, IL-1α, IL-6, IL-8 and TNF-α in patients with RIOM so as to validate their role in the pathobiology of the disease. Blood samples were collected and serum of 45 patients isolated with clinical signs and symptoms of mucositis and 10 healthy controls were also included in the study. The expression level of NF-κß, IL-1α, IL-6, IL-8, TNF-α was investigated using ELISA. Mann Whitney U test was applied to find the significance of the expression of these markers in RIOM patients as compared to normal healthy controls and significant expression (P< 0.05) for NF-κß, IL-6, TNF-α and non-significant expression (P > 0.05) IL-1α and IL-8 was found. No significant change in the expression level of the cytokines was observed for patients undergoing chemotherapy and radiation therapy as well as those receiving only the radiation therapy as a part of their treatment. We have also found less expression in grade 1 of mucositis as compared to grade 4. Pro- inflammatory cytokines indeed play a vital role in the pathogenesis as well as progression of RIOM (AU)

Methodology: Major lower limb amputations were identified according to ICD-10 criteria. Data was retrospectively collected. Type of the amputation, indication for the amputation, gender and age of the patients, and mortality were noted

Results: Eighty-five cases of major lower limb amputations were analyzed, including 43 above-knee amputations, 40 below-knee amputations, and 2 through-knee amputations. Most of the patients were in their 7th [38.8%, n=33] and the 8th [21%, n=18] decade of life. Female to male ratio was 1:1.7. Indications of lower extremity amputation were diabetic foot ulcer [37.6%, n=32], peripheral vascular disease [31.7%, n=27], followed by trauma [n=6], acute limb ischemia and infections [n=5 each], chronic osteomyelitis [n=4], tumors [n=3], elephantiasis, pressure sore and chronic wound [n=1 each]. Overall diabetes frequency was 52.9% [n=45]. In-hospital mortality rate was 9.4%. Main cause of deaths was septicemia

Conclusion: In the study population, major lower limb amputations were more common in males compared to females, with highest incidence in the 7th and 8th decades. Diabetes mellitus contributed to more than 50% of amputations directly or indirectly, and septicemia was responsible for the most mortality

Association between Family Developmental Stages and Clinical Manifestations of Patients with Psychosomatic Morbidity Presenting at a Primary Care Clinic in South-West Nigeria.

Aim: This study aimed to find out the relationship between the clinical manifestations of patients with psychosomatic morbidity (PSM) and their family developmental stages. Study Design: A cross sectional study. Place and Duration of Study: The study period span between February 1st and April 30th 2013, during which patients who presented at the General Outpatient (GOP) clinic of the University College Hospital, Ibadan for various complaints were encountered. Methods: A sample of 360 patients with varying forms of PSM identified by five or more from the symptoms in the primary evaluation of mental disorder- patient health questionnaire somatoform, anxiety and depression modules (PRIME-MD PHQ SADs) was recruited consecutively. The international classification for primary care second electronic version (ICPC-2E) was used to categorize the clinical manifestations of respondents while Stevenson’s family developmental model classified the family developmental stages into emerging, crystallizing, interacting and actualizing family. Data were analyzed using statistical package for social sciences soft ware version 17. Statistical significance level was set at p ≤ 0.05. Results: Among the 360 respondents studied, 275 were married with age range between 19 and 80 years, 62.5% lived with their spouses, 3.1% divorced∕ separated and 10.8% were widowed. Majority was females (74.9%) and the predominant family developmental stage was the crystallizing family (30.2%). General and unspecified physical (GUP) complaints were the commonest clinical manifestation seen in all the stages except the emerging family which has gynaecological complaints. Comparing the mean scores of married respondents with moderate-severe PSM and family stages shows that being married and living with spouses may be protective against severe forms of PSM (P = .04). On the other hand, comparing the mean scores of single and married respondents with moderate-severe PSM shows that respondents who are single may come with severe forms of somatoform disorder when compared with other single respondents with anxiety or depressive disorder (P < .05). There is however no relationship between the family developmental stage and severity of PSM. Conclusion: There was interplay between medically unexplained physical complaints and patient’s family characteristics. Being married and living with spouses may be protective against severe forms of PSM.

Rosmarinus officinalis L. increases Caenorhabditis elegans stress resistance and longevity in a DAF-16, HSF-1 and SKN-1-dependent manner

Improving overall health and quality of life, preventing diseases and increasing life expectancy are key concerns in the field of public health. The search for antioxidants that can inhibit oxidative damage in cells has received a lot of attention. Rosmarinus officinalis L. represents an exceptionally rich source of bioactive compounds with pharmacological properties. In the present study, we explored the effects of the ethanolic extract of R. officinalis (eeRo) on stress resistance and longevity using the non-parasitic nematode Caenorhabditis elegans as a model. We report for the first time that eeRo increased resistance against oxidative and thermal stress and extended C. elegans longevity in an insulin/IGF signaling pathway-dependent manner. These data emphasize the eeRo beneficial effects on C. elegans under stress.
