RESUMEN

Background: Elderly hip fractures represent a global health care burden. Several reports expected a massive increase in the incidence of hip fractures by the next few decades. Knowing the epidemiology of hip fractures is crucial for planning health care policies. The purpose of this study is to provide a nationwide epidemiological overview of hip fractures in Jordan and to report the perioperative outcomes that may help to improve the delivered healthcare. . Methods: We conducted a retrospective study at 2 university hospitals and 2 major governmental hospitals in Jordan. We reviewed the records for all patients (age >55 years) who were diagnosed with hip fractures over a 3 years duration (2019-2021). We documented the patient's characteristics and the perioperative data (including preoperative, intraoperative, and postoperative details including the 1-year mortality). . Results: The total number of included patients was 1268; more than half (53.7%) were females. The mean age is 75 years (SD 9.7). The most common fracture type was trochanteric (66.2%) . 7% of patients had a prior contralateral hip fracture . The average time from admission to surgery was 2.96 days (SD 2.63). The surgery was done within 48 hours for 56.7% of patients. Approximately, one-third of all patients (34.5%) received a blood transfusion. The average length of hospital stay is 7.44 days (SD 5). The overall rate of postoperative thromboembolic events, readmission within 1 month, and revision for the same surgery are 2.4% , 10.7% , and 3% respectively. The 1-month, 6-month, and 12-month mortality rates are 4.5%, 9.1%, and 12.8% respectively. Conclusion: The annual incidence of elderly hip fractures in Jordan is approximately 96 per 100,000 individuals. The 1-year mortality rate of hip fractures in Jordan is 12.8% . Both findings are in the lower range of nearby Arab countries.

RESUMEN

Background Lung cancer is one of the leading cause of cancer related death. Most common histopathology of lung cancer is non-small cell carcinoma of which adenocarcinoma is the most common. There are limited number of studies done in Nepal to know different aspects of lung cancer. Objective To know demographic parameters of patients diagnosed as lung cancer in a university hospital. The study also aims to know the different histopathological diagnosis of lung cancer. Method All the patients presenting to outpatient department (Cardio Thoracic and Vascular unit) of Dhulikhel Hospital, if are diagnosed as cancer of lung/bronchus will be included in the study. The duration of the study was January 2017 to December 2021. The details on age, gender, presenting symptoms, histopathology of lung cancer, operability will be included in database and will be analyzed. Result There were total of 127 patients diagnosed as lung cancer. Male:female ratio was 1.7:1. Overall mean age was 63.23 years (SD 13.5 years, Range 19-89 years). Non small cell carcinoma was the most common type of lung cancer with 83.7%. In non small cell carcinoma, most common type was Squamous cell carcinoma followed by undifferentiated and Adenocarcinoma. Only five (3.93%) cases were in operable stage. Conclusion Despite the fact that lung cancer is one of the most common cancer, patients usually present late and moslty are not in operable stage. This study shows that squamous cell carcinoma is the most common histopathology in lung cancer cases.

RESUMEN

Appendiceal carcinoids are the most frequent tumors arising from the appendix, comprising between 32 and 57% of all the appendiceal tumors. The gross appearance of the appendix showed perforation at the tip with 30 ml of periappendicular collection. On histopathological examination, carcinoid tumor on the tip of appendix was found with tumor cells arranged in tubules, acini and nests infiltrating the muscularis propria and sub serosa. Perineural and vascular invasion was not seen. Immunohistochemistry for Synaptophysin was positive with Ki-67 labelling index of 2%. We present a case of appendiceal neuroendocrine tumor with the chief complaint of acute appendicitis.

RESUMEN

Le diastème du grec diastèmà (interstice) se définit comme étant l'existence d'espace entre les dents d'une même arcade. Les objectifs de l'étude étaient de déterminer le profil épidémiologique des diastèmes; décrire les formes cliniques rencontrées, assurer une prise en charge. PATIENTS ET MÉTHODE: Il s'agissait d'une étude prospective de type descriptif effectuée à l'hôpital national Donka, elle avait duré sept mois, allant du 1er Mars au 30 septembre 2019. RÉSULTATS: Le sexe féminin prédominait avec 77,7% contre 22,2 % de sexe masculin, donnant un ratio (f/h) = 3,5. La tranche d'âge de 21-23 ans (tout sexe confondu) était la plus représentée avec un pourcentage de 44,4%. La tonicité du frein labial médian avec 29,62% était l'étiologie principale du diastème inter incisif. Le diastème était plus fréquent au maxillaire avec des valeurs respectives de 33,33% de diastème des dents du bloc incisivo canin et 29,62% de diastème inter incisif soit au total 62,96 %. Le traitement fut chirurgical, orthodontique et prothétique. CONCLUSION:Le diastème reste l'une des anomalies orthodontiques fréquente dans nos pays. Considéré par certains comme un excès de place sur l'arcade dentaire, il est cependant apprécié par d'autres, surtout en Afrique de l'ouest où il est souvent considéré par la population comme signe de chance, de beauté, d'où son impact socio-culturel.

RESUMEN

Endometriosis is principally a disease of women in active reproductive life. Although it is rare, foci of endometrial tissue may be seen in the bowel, the umbilicus, abdominal surgical scars and in the lungs. Inguinal endometriosis is challenging to the clinicians and pathologist and often diagnosed accidentally. We present a case of inguinal endometriosis mimicking neoplasm. A 40 year old woman presented with a swelling in the right inguinal region associated with cyclical pain. In view of presence of atypical cells in fine needle aspiration cytology, metastatic carcinoma was rendered as diagnosis. Histopathological examination revealed endometrial glands and stroma which was further confirmed by immunohistochemistry. Diagnosis of inguinal endometriosis is difficult and often challenging because of unusual site. The clinician must have high index of suspicion with any patient who has cyclical symptoms. A good history and physical examination can guide clinical diagnosis of endometriosis.

RESUMEN

OBJECTIVES: To examine the influence of emergency department (ED) waiting time estimate provision on the satisfaction of patients.  Methods: This was a randomized controlled trial at King Abdulaziz Medical City, Riyadh, Saudi Arabia between September 2017 and May 2018. It included 18 to 70 years old Arabic-speaking acute care patients. After being divided into 2 groups, the intervention group alone was provided waiting time estimates. Both groups answered 2 questionnaires evaluating their satisfaction and illness perception before and after seeing a doctor. Results: One-hundred patients were included. No significant difference found in waiting time satisfaction scores between groups (intervention (5.92/10±3.13), control (5.45/10±3.38), p=0.476). Demographics and illness perception had an insignificant impact on satisfaction. Waiting time estimate was preferred by most participants (70%). Conclusion: Providing waiting time estimation did not affect satisfaction but was preferred to have in the ED by most.

RESUMEN

CONTEXT: Epilepsy is said to be intractable when two or more trials of anticonvulsants fail to control the seizures. Literature suggests that intractable epilepsy carries a higher morbidity than controlled epilepsy in children and their caregivers. AIMS: The aim of this study is to assess the quality of life (QOL) in children with intractable epilepsy (IE) in KASCH, a tertiary care hospital in Riyadh, Saudi Arabia. SETTINGS AND DESIGN: This is a cross-sectional study utilizing a self-administered questionnaire filled by caregivers of epileptic patients visiting the outpatient neurology clinics. METHODS AND MATERIALS: The quality of life in childhood epilepsy (QOLCE-55) scale examined four domains of life: cognitive, emotional, social, and physical. The sample consisted of 59 parents whose children aged 4-14 of either sex. STATISTICAL ANALYSIS USED: The collected data were analyzed by Statistical Package for the Social Sciences (SPSS) version 22. RESULTS: The mean age of children was 8.9 (SD = 2.9). The mean QOL was 52.8 (SD = 12.9), which reflected a poor QOL. Age was not related to the QOL. Gender was significantly associated with the total and social scores, (P = 0.04) (P = 0.001), respectively. Out of all comorbidities, global developmental delay (GDD) and encephalopathy were significantly associated with the QOL (P < 0.05). CONCLUSIONS: Intractable epilepsy impacted all functioning domains of life rendering a poor QOL. Males have reported better QOL and social functioning compared to females. Children with GDD and encephalopathy showed lower well-being.

RESUMEN

In mammalian cells, responses to hypoxia at the molecular transduction level are hallmarks of adaptation and survival under oxygen deprivation conditions. In this study, the protein expression patterns of mitogen-activated protein kinases (MAPKs) are investigated under hypoxia in primary cortical neurons and in a model of organotypic hippocampal slices in neonatal Sprague-Dawley rats. Abrupt fluctuations in MAPK expression can occur during anoxia, hypoxia, and relative hyperoxic shifts (e.g., reoxygenation); therefore, phosphorylation and dephosphorylation states could be crucial factors in metabolic reorganization for withstanding anaerobiosis. Whole cellular protein extracts were analyzed for the phosphorylation of MAPKp(p38) and MAPK(ERK-1/2 (p44/p42)) at threonine and tyrosine residues (Thr(180)/Tyr(182)) at different time periods of hypoxic exposure relative to a fixed normoxia control. The phospho-MAPK(p38) (p-MAPK(p38)) to MAPK(p38) relative unit ratio revealed that MAPK(p38) expression increased in cortical neurons after 5 and 10 min, but decreased abruptly afterwards (20 - 120 min). The expression of phospho-MAPK(ERK-1) (p-MAPK(ERK-1/p44)), however, decreased whereas that of p-MAPK(ERK-2/p42) increased compared to normoxia. In rat hippocampal slices (RHS), the expression of p-MAPK(p38) was slightly but significantly higher in hypoxia, whereas the expression of p-MAPK(ERK-2/p42) increased and that of p-MAPK(ERK-1/p44) was intangible. This indicates that in cortical neurons hypoxia differentially upregulated the phosphorylation activation states of MAPK(p38) and MAPK(ERK-1/2 (p44/p42)), whereas in the RHS model MAPK(p38) and MAPK(ERK-2/p42), but not MAPK(ERK-1/p44), phosphorylation states were upregulated in response to hypoxia. The neuroimmunological molecular patterns of the differential MAPK phosphorylation in vitro and ex vivo in response to hypoxic shift indicated a significant role for these kinases in cellular adaptation to oxygen deprivation, and thereby may identify physiologic and neuroprotective responsive signaling cofactors and pathways in cortical and hippocampal neurons during hypoxia.

RESUMEN

Retrospectively, we have measured the antioxidant activity and a variety of antioxidant compounds under versatile extraction conditions of sweet cherry (Prunus avium) extracts. Further in this study, in order to understand the biochemical constituents and antioxidant activities of a variety of extracts of black sour cherries (P. cerasus), a related species, antioxidant compounds, including L-ascorbic acid (vitamin C), phenols, flavonoids, and anthocyanins, and the total antioxidant activity were simultaneously measured under varying extraction conditions (mild heating and brief microwave exposure) for: i) whole juice extracts (WJE), ii) methanol-extracted juice (MEJ), iii) ddH2O-extracted pomace (dPOM), and iv) methanol-extracted pomace (mPOM). The antioxidant activity for WJE was substantially increased with mild and prolonged exposure to either heating or microwave, such that the % inhibition against 2,2-diphenyl-1-bspicrylhydrazyl (DPPH) followed a positive correlation (heating, 5-20 min.; microwave, 1-2 min.), insignificant with MEJ and dPOM, whereas with mPOM there was sharp downregulation. L-Ascorbic acid content was not affected with mild to prolonged heating or microwave exposure (WEJ and mPOM), except a mild increase with MEJ and dPOM. Similarly, total phenols assessed showed no significant variations, as compared with control extracts, except a mild decrease with exposure for mPOM. In a manner similar to L-ascorbic acid, total flavonoid content was increased under varying conditions for WEJ and MEJ, and slightly decreased for dPOM and mPOM. On the other hand, anthocyanins showed differential variations with exposure (up- and downregulation). Assessment of extraction means as compared with WJE revealed sharp increase in the antioxidant activity for MEJ, dPOM and mPOM, significant increase in L-ascorbic acid, total phenol, and flavonoid contents for MEJ, dPOM and mPOM, and mild decrease in anthocyanin contents for MEJ, dPOM, and mPOM. These results substantiate the measurable antioxidant activities and contents of P. cerasus extracts under versatile conditions of mild exposure, an effect bearing significant fluctuation with biochemical properties. Since many of those molecules are known to have immuno-biochemical constituencies, antioxidant compounds in sour cherries may have putative antiinflammatory potential and applications in medicinal chemistry, corroborating the observation of regulating and attenuating the growth of microorganisms of medical importance in vitro.

RESUMEN

Previously, we have meticulously examined the efficacy of the measurable antimicrobial activity of sweet cherry (Prunus avium) extracts on a wide spectrum of gram-positive and gram-negative bacteria, in addition to the fungus, Candida albicans, a priori. In order to further understand the biochemical constituents and antioxidant activities of a variety of extracts of sweet cherries, antioxidant compounds of immunological significance, including L-ascorbic acid (vitamin C), phenols, flavonoids, and anthocyanins, and the total antioxidant (free radical scavenging) activity were simultaneously measured under varying and versatile extraction conditions (mild heating [5, 10 and 20 min.], and brief microwave exposure [1, 2 and 5 min.]) for a variety of extracts: i) whole juice extracts (WJE), ii) methanol-extracted juice (MEJ), iii) ddH2O-extracted pomace (dPOM), and iv) methanol-extracted pomace (mPOM). The antioxidant activity under the versatile extraction conditions adopted in this study was conspicuously reduced, such that the % inhibition against 2,2- diphenyl-1-picrylhydrazyl (DPPH) followed an inverse, negative correlational trendline. Moreover, ascorbic acid content was not affected with mild to prolonged heating or microwave exposure, except tangibly with dPOM and mPOM. The total phenols content assessed showed no significant variations, as compared with control extracts. In a manner similar to ascorbic acid, total flavonoids were mildly reduced under varying conditions, an effect mimicked to a certain extent with anthocyanins. Assessment of extraction means as compared with WJE revealed sharp decrease in the antioxidant activity for dPOM and mPOM, significant increase in L-ascorbic acid, total phenol, and flavonoid contents for MEJ, dPOM, and mPOM, and mild decrease in anthocyanin contents for dPOM and mPOM. These results confirm the measurable antioxidant activities and contents of P. avium extracts under versatile conditions of mild exposure, an effect bearing significant biochemical properties of a variety of extraction methods. Further studies are currently investigating the effect of specific antioxidants of P. avium on microbial growth in vitro per se. Since many of the aforementioned molecules hold immunobiochemical constituencies, antioxidant compounds in sweet cherries may have putative anti-inflammatory potential in medicinal chemistry, corroborating the observation of regulating/attenuating the growth of microorganisms of medical importance in vitro.

RESUMEN

Genes coding for sarcomeric proteins may play a key role in muscle mass accretion and meat production. Screening a skeletal muscle cDNA library we isolated two partial sequences coding for the sarcomeric myopalladin and titin genes. In the present work we identified three SNPs in the 3' untranslated region, two at the myopalladin locus and one at the titin locus. Myopalladin was mapped on porcine chromosome (SSC) 14 using a somatic cell hybrid panel, a radiation hybrid panel and by linkage mapping. The linkage mapping of titin confirmed the position on SSC15. Then we analysed the allelic distribution of the alleles at both loci in six different porcine breeds. The analysis of the allele frequencies for these two loci in extremely divergent groups of pigs selected according to lean cuts (LC) and average daily gain (ADG) approached the significance level for myopalladin and LC trait. Further studies are needed to test the presence of a putative effect of myopalladin on lean meat content.
