Background: Literature comparing different alternatives for paincontrol in the immediate postoperative period of pediatric acute appendicitis (PAA) is scarce.Materials and methods: We prospectively compared the analgesicand emetogenic profile of intravenous ibuprofen and metamizole in theimmediate postoperative period of PAA. For this purpose, we used asample of patients operated on in 2021 in our center. Participants wererecruited on arrival at the Emergency Department and histopathologi-cal confirmation of the diagnosis was obtained in all of them. Pain wasevaluated every 8 hours after the surgery with validated visual analogscales ranging from 0 to 10 points. Repeated measures ANOVA wasused to compare the evolution of pain in the 48 hours after surgerybetween the two groups. Results: The sample included 95 patients (65% males) with a meanage of 9.7 years (sd: 3.14). 41 patients were treated with Ibuprofen(group 1) and 54 with metamizole (group 2). No significant differ-ences were found in the level of pain either in the comparisons of pointmeasurements or in its evolution in the 48 hours after surgery (p= 0.58).After adjusting for the received fluid therapy, children in the metamizolegroup had significantly more emetic episodes and needed significantlymore doses of ondansetron. Conclusions: In our cohort, ibuprofen had a similar analgesic ef-ficacy and a better emetogenic profile than metamizole in the immediatepostoperative period of PAA. Future prospective, adequately controlledstudies with larger sample sizes are needed to validate these findings.(AU)

There are multiple reports already regarding acute carbon monoxide (CO) poisoning in the Philippines secondary to the misuse of portable generators, especially during times of typhoons. We present a case of unintentional carbon monoxide poisoning in a Filipino household wherein our index patient is among the five members who were unconscious before they were rushed to the hospital. Three of the household members, on the other hand, were found dead. The index patient had an increased serum fraction percentage of carboxyhemoglobin level and presented with rhabdomyolysis during admission. Neuroimaging confirmed a hypoxic-ischemic encephalopathy secondary to carbon monoxide intoxication. Even without hyperbaric oxygen therapy, the patient improved with adequate hydration, early rehabilitation, and trauma-focused psychotherapy.
RESUMO
The formation of a porous oxide surface doped with osteoconductive elements, Ca, P and Mg, to enhance osseointegration, was achieved through micro arc oxidation. Micro arc oxidation parameters, such as electrolyte composition, concentration and applied voltage, were studied to understand their effect on the morphology and chemical composition of the samples surface. Considering the optimum atomic concentration reported in literature for each osteoconductive element, microporous Ta anodic oxide samples treated with calcium acetate (CaA) and ß-glycerophosphate (ß-GP) revealed that an increase of ß-GP molarity in the electrolyte boosts Ca incorporation, as well as, increasing the porosity. In adding magnesium acetate (MgA) to the electrolyte, when composed by CaA + ß-GP, both addition and variation of MgA did not affect the surface morphology along the samples, being incorporated into the oxide layer for 0.1 M. Finally, in vitro tests were carried out to study the biocompatibility of Ta, to verify the cytotoxicity of the samples and their behavior towards cells, by performing adhesion and differentiation tests with the MC3T3-E1 cell line. Cytotoxicity tests revealed that the samples were non-toxic. Despite none of the samples having been raised up through cell adhesion tests, cell differentiation revealed promising results for the Ta-CaP.

Biocompatible and antibacterial multi-layer coatings of hydroxyapatite (HA)-Ag/SiO2/TiN/Ti were obtained on the Ti-6Al-4V alloy, by means of the magnetron sputtering technique. During characterization of the coatings, the chemical composition was evaluated by energy dispersive X-ray spectroscopy and the phase analysis was carried out by X-ray diffraction. The morphology of the coatings was observed by field emission scanning electron microscopy, while transmission electron microscopy was used to appreciate their structure. The adhesion of the coatings to the substrate was evaluated by micro scratch test. The in vitro biological response was evaluated in terms of cytotoxicity, adhesion and differentiation of mouse mesenchymal stem cells, as well as adhesion and bacterial viability of Staphylococcus aureus strain. Through the compositional study carried out, the deposition of the HA phase was verified, with a Ca/P ratio close to 1.67 and the characteristic diffraction peaks of this compound. The structural study of the coatings evidenced the obtention of multi-layer architectures. The use of an intermediate SiO2/TiN/Ti trilayer was found to improve adhesion between HA-Ag and the substrate by 84%. Finally, the in vitro biological tests carried out indicated a potentially non-toxic character in the coatings. Additionally, an antibacterial effect was registered at low concentrations of Ag (<0.25 mg/L).

Se reportan dos casos de bacteriemia por C. perfringens asociados a choque séptico fulminante en recién nacidos con enterocolitis necrosante grave.
Abstract Clostridium species are anaerobic, spore, forming gram-positive bacteria that are widely spread in the environment. Clostridium perfringens infections in neonates are extremely rare. Severe anaerobic sepsis, including septic shock, is an unusual clinical event in this group of patients. We highlight two cases of C. perfringens bacteremia associated with fulminant septic shock in neonates with severe necrotizing enterocolitis.
RESUMO
In the sensors field, titanium based coatings are being used for the acquisition/application of electrical signals from/to piezoelectric materials. In this particular case, sensors are used to detect dynamic mechanical loads at early stages after intervention of problems associated with prostheses implantation. The aim of this work is to select an adequate electrode for sensor applications capable, in an initial stage to avoid bone cell adhesion, but at a long stage, permit osteointegration and osteoinduction. This work reports on the evaluation of osteoblast MC3T3-E1 cells behavior in terms of proliferation, adhesion and long-term differentiation of two different systems used as sensor electrodes: Ti1-xAgx and Ag-TiNx deposited by d.c. and pulsed magnetron sputtering at room temperature on poly(vinylidene fluoride) (PVDF). The results indicated an improved effect of Ag-TiNx electrodes compared with Ti1-xAgx and TiN, in terms of diminished cell adhesion and proliferation at an initial cell culture stage. Nevertheless, when cell culture time is longer, cells grown onto Ag-TiNx electrodes are capable to proliferate and also differentiate at proper rates, indicating the suitability of this coating for sensor application in prostheses devices. Thus, the Ag-TiNx system was considered the most promising electrode for tissue engineering applications in the design of sensors for prostheses to detect dynamic mechanical loads.

Introduction@#Breast cancer remains to be a public health problem in the Philippines. This study determined the level of breast cancer awareness among female non-medical students from selected private colleges in Quezon City. @*Methods@#This was a descriptive cross-sectional survey, and data collection was done on a single occasion. The study population was chosen via convenience sampling. The survey asked about the respondents' ideas on awareness, beliefs, perceived personal risk, perceived seriousness, and knowledge of etiology, diagnosis and management of breast cancer.@*Results@#Majority of the respondents associated lifestyle factors (smoking) with the development of breast cancer. Four-fifths regarded Western medicine as a mainstay of treatment, however, a significant proportion believed that breast cancer could be adequately managed and controlled with complementary and alternative treatments. Around 25% of respondents considered themselves at risk for breast cancer and 40% did not know. Close to 65% said that family history was a risk factor. Almost 50% never heard of self-breast examination; of those who knew about it, only 15% practiced it monthly. The respondents had varied answers when asked about the common symptoms and signs of breast cancer. At least two-thirds of respondents said that the treatment for breast cancer includes surgery and radiation therapy. Majority (79.8%) opined that having an education program would increase the level of awareness of the general public.@*Conclusion @#The students surveyed were generally aware about breast cancer, including aspects of epidemiology, diagnosis and management. The study also a revealed a number of misconceptions regarding breast cancer.

A self-consistent generalized Langevin-equation theory is proposed to describe the self- and collective dynamics of a liquid of linear Brownian particles. The equations of motion for the spherical harmonics projections of the collective and self-intermediate-scattering functions, F_{lm,lm}(k,t) and F_{lm,lm}^{S}(k,t), are derived as a contraction of the description involving the stochastic equations of the corresponding tensorial one-particle density n_{lm}(k,t) and the translational (α=T) and rotational (α=R) current densities j_{lm}^{α}(k,t). Similar to the spherical case, these dynamic equations require as an external input the equilibrium structural properties of the system contained in the projections of the static structure factor, denoted by S_{lm,lm}(k). Complementing these exact equations with simple (Vineyard-like) approximate relations for the collective and the self-memory functions we propose a closed self-consistent set of equations for the dynamic properties involved. In the long-time asymptotic limit, these equations become the so-called bifurcation equations, whose solutions (the nonergodicity parameters) can be written, extending the spherical case, in terms of one translational and one orientational scalar dynamic order parameter, γ_{T} and γ_{R}, which characterize the possible dynamical arrest transitions of the system. As a concrete illustrative application of this theory we determine the dynamic arrest diagram of the dipolar hard-sphere fluid. In qualitative agreement with mode coupling theory, the present self-consistent equations also predict three different regions in the state space spanned by the macroscopic control parameters η (volume fraction) and T* (scaled temperature): a region of fully ergodic states, a region of mixed states, in which the translational degrees of freedom become arrested while the orientational degrees of freedom remain ergodic, and a region of fully nonergodic states.
RESUMO
Hip hemiarthroplasty (HHA) and total hip arthroplasty (THA) infections are usually considered as one entity; however, they may show important differences. We analyze these differences, as well as predictors of treatment failure (TF) and poor functional status among patients with prosthetic hip infections (PHIs). A multicenter cohort study of consecutive patients with PHIs was performed. The main outcome variable was TF after the first surgical treatment performed to treat the infection. Multivariate analysis was used to identify predictors of TF. A total of 127 patients with PHI were included (43 HHA, 84 THA). Patients with HHA infections were more frequently women (88% vs. 54%; p < 0.001), had comorbidities (86% vs. 67%, p = 0.02), and were older (median age 79 vs. 65 years, p < 0.001), and the reason for arthroplasty was more frequently a fracture (100% vs. 18%, p < 0.001). Failure of initial treatment and crude mortality were more frequent among HHA patients (44% vs. 23%, p = 0.01 and 28% vs. 7%, p = 0.001, respectively). However, HHA was not associated with TF in the multivariate analysis when hip fracture was considered; thus, variables independently associated with TF were hip fracture, inadequate surgical management, prosthesis retention, and higher C-reactive protein level. Failure of the first surgical treatment was associated with poorer functional status. HHA and THA infections showed significant differences in epidemiology, clinical features, and outcome. Although patients with HHA infections had a higher risk of TF, this was related to the reason for hip implant: a hip fracture. Success of the initial management of infection is a predictor of better clinical and functional outcome.

La falta de alivio adecuado del dolor postoperatorio tiene efectos negativos en los resultados de la cirugía y en la satisfacción de los pacientes. Hoy en día el dolor continúa siendo sub tratado en muchos lugares del mundo La incidencia de dolor moderado a severo está entre 30 a 80 por ciento de los postoperados. Un programa de dolor agudo (PDA) es muy recomendable en las instituciones y debe basarse en guías clínicas con la mejor evidencia disponible. Objetivos: Evaluación del PDA de Clínica Alemana de Santiago con respecto a la eficacia y seguridad del tratamiento del dolor y a las opiniones del paciente sobre su experiencia de dolor y la atención recibida por el equipo de dolor (EDA) y enfermeras. Material y Métodos: Revisamos los datos electrónicos de todos los pacientes manejados por el PDA entre diciembre de 2010 y septiembre de 2011 (993 pacientes). También se realizó una encuesta con 9 preguntas a una muestra de 163 pacientes por investigadores ciegos. Resultados: El promedio de edad fue 51,4 +/- 18 años con un 51 por ciento de mujeres y 49 por ciento hombres. Los pacientes tenían dolor agudo postoperatorio (93 por ciento) y dolor agudo no quirúrgico (7 por ciento).El promedio de control por el PDA fue de 2,6 +/- 1,19 días. Las técnicas analgésicas fueron multimodales en todos los casos. La frecuencia de las técnicas utilizadas fue: PCA IV 46 por ciento, catéteres peridurales 35 por ciento y catéteres perineurales 18 por ciento. La morfina fue el opioide más usado (63,8 por ciento). Todos los pacientes recibieron de 1 a 3 analgésicos no opioides. En 11 por ciento se usó medicación coadyuvante. El promedio de intensidad del dolor registrado el primer día fue de 1,4 en reposo y 3,3 dinámico (escala 0 a 10) y estos valores disminuyeron a 0,86 y 2,5 respectivamente el día del alta del programa. Casi todos los valores estuvieron en el rango de dolor leve (0 a 3). No se presentaron complicaciones en relación a los métodos de analgesia...
Lack of adequate postoperative pain relief has negative effects on patient outcome and satisfaction. Nowadays pain continues being undertreated all over the world. Incidence of moderate to severe pain is between 30 to 80 percent of postoperative patients. An Acute Pain Program (APP) is strongly recommended in institutions and must be based on clinical guidelines with the best evidence available. Objectives: Evaluation of the APP of Clínica Alemana regarding the efficacy and safety of pain management and patients opinion about their pain experience and care provided by the pain team and nurses. Methods: We reviewed the electronic data of all patients treated by the APP between December 2010 and September 2011 (993 patients). Also a group of 163 patients was interviewed with a survey of nine questions by blind investigators. Results: Mean age was 51.4 +/- 18 years; 51 percent female and 49 percent male. Patients had acute postoperative pain (93 percent) and non-surgical acute pain (7 percent). The mean stay in APP control was 2.6 +/- 1.19days. Analgesic techniques were multimodal analgesia: iv PCA 46 percent, epidural catheters 35 percent and perineural catheters 18 percent. Morphine was the more used opioid (63.8 percent). All patients were treated with 1 to 3 non opioid analgesics. Adjuvant medication was used in 11 percent of the patients. The mean pain intensity registered the first day was 1.4 at rest and 3.3 dynamic (0-10 scale) and these values decreased to 0.86 and 2.5 respectively on the day of discharge. Almost all values were in range of mild pain (0-3). No complications occurred related to analgesia methods...

Objetivos. En la intubación fibroscópica, el hecho de gozar de una visión directa y en tiempo real, no nos asegura el correcto avance del tubo endotraqueal (TET) hasta su posición intratraqueal. El empleo de cánulas orales ayuda a la consecución de una vía aérea libre para el paso del fibroscopio y el TET. Comparamos la cánula VAMA(R) y la cánula Berman(R) en cuanto a tiempo necesario para la intubación, visión fibroscópica y facilidad de paso del TET. Pacientes y método. Noventa pacientes sin criterios de vía aérea difícil fueron randomizados en dos grupos, B y V, según el tipo de cánula empleada. Tras inducir anestesia general, se procedió a la intubación con fibroscopio flexible, midiendo tiempos de fibroscopia e intubación, intentos de fibroscopia, calidad de visión fibroscópica y grado de dificultad en el paso del TET. Resultados. No se obtuvieron diferencias estadísticamente significativas entre ambas cánulas, si bien, la tendencia apuntaba a menores tiempo de intubación (p=0,292) y menor dificultad al paso del TET (p=0,447). Con ambos dispositivos, la calidad de visión fue buena, encontrando únicamente algún grado de obstrucción en la vía aérea en el 22% de los pacientes. En ningún caso esta obstrucción fue total, por lo que todos los pacientes pudieron ser intubados correctamente. Conclusiones. La cánula VAMA® representa una alternativa eficaz a las clásicas cánulas de intubación fibroasistida. Además, su novedoso diseño ofrece ciertas ventajas para la correcta orientación del fibroscopio y la retirada de la cánula tras la intubación (AU)
Objectives. In fibroscopic intubation, the fact of achieving a direct view in real time does not guarantee the correct advance of the endotracheal tube (ET) to its intratracheal position. The use of oral cannulas helps in achieving a free airway in order to pass the fibroscope and the ET. This study compares the VAMA® (V) and Berman® (B) cannulas as regards the time required for the intubation, fibroscopic view, and the ease in positioning the ET. Patients and methods. 90 patients with no signs of difficult airway were randomised into 2 groups, Berman(R) (B) and VAMA(R) (V), depending on the type of cannula employed. After inducing general anaesthesia, they were intubated using a flexible fibroscope. The fibroscope and intubation times were recorded, as well as the quality of the fibroscopic view, and the level of difficulty in positioning the ET. Results. No statistically significant differences were observed between the cannulas, although the intubation time (P=.292) and the difficulty found in positioning the ET were slightly less (P=.447) in the VAMA® group compared to the Berman® group. The vision quality was good with both devices, with only some degree of obstruction being encountered in only 22% of the patients. In no case was there complete obstruction, thus all the patients could be intubated correctly. Conclusions. The VAMA® cannula is an effective alternative to the classic cannulas for fibreoptic assisted intubation. Furthermore, the novel design provides advantages for the correct orientation of the fiberscope and the withdrawal of the cannula after intubation(AU)

BACKGROUND: Free flap reconstruction is a common procedure for through-and-through lip and cheek complex defects after cancer ablation. However, oral incompetence with unacceptable bulky flap appearance invariably occurs and needs a secondary revisionary procedure. The purpose of this article was to present our method to improve the oral competence and cosmetic appearance by the stair-step technique of flap revision. METHODS: Fourteen patients who had undergone flap folding reconstruction of the lip and cheek complex defect resulting in oral incontinence were involved in this study. Thirteen patients had been treated with an anterolateral thigh flap and 1 patient had been treated with a fibular osteocutaneous flap. This revisionary stair-step technique was combined with simultaneous liposuction of the bulky flap in all cases. RESULTS: Adequate oral continence and good contour was achieved in 12 patients. The remaining 2 patients still had mild drooling, which was managed successfully with a second stair-step flap. CONCLUSION: This technique is a valuable option for revision of lower lip deformity.

Single flap for complex hypopharyngoesophageal and anterior neck skin defect reconstruction is still a challenge for reconstructive surgeons. Herein, we present five patients, with advanced hypopharyngeal cancer and anterior neck skin invasion, which received a single anterolateral thigh (ALT) fasciocutaneous flap for composite inner pharyngeal and outer skin defect reconstruction after wide composite resection. Two ALT flaps were divided into two distinct paddles supplied by two or more separate perforators, one part for reconstructing the inner pharyngeal defect and another for neck skin coverage. Three ALT flaps only supplied by one sizable perforator could not be divided and de-epithelization of mid-part had to be done to reconstruct both defects with the single flap. The results revealed survival of all flaps. There were no flap loss, fistulas, or bleeding complications. All patients recovered uneventfully and could eat a soft diet to regular diet postoperatively. In conclusion, one-staged reconstruction of complex pharyngoesophageal and external skin defects after extensive oncological resection is feasible using a single ALT fasciocutaneous free flap.
