A fungal illness called cryptococcal meningitis is most often thought of as an opportunistic infection that affects immunocompromised people, typically those who have HIV infection. Numerous problems are linked to it, including widespread illness and neurologic ones such as intracranial hypertension, cerebral infarcts, vision loss, and other abnormalities. Here is a case 18-year-old male patient, who presented with persistent headache and fever. A lumbar puncture revealed a cryptococcal infection in him. His workup indicated no known underlying illness that may have compromised his immune system. CSF was then tested for cryptococcal species using an Indian ink preparation, and the results were positive. He was admitted to the hospital for initiation of antifungal therapy with amphotericin B along with serial serum creatinine and electrolytes levels and after the 5th day of getting amphotericin B, he had shown remarkable improvement in total symptomatology.

Published: July 2023

Introduction: Fosfomycin has started to be used again as a possible therapeutic alternative in cases injected with resistant bacterial pathogens. Its primary mechanism of action is inhibition of the first step of cell wall synthesis; This mechanism is effective against both Gram-positive and Gram- negative bacterial groups. However, its clinical efficacy against bacteria that develop multidrug resistance is largely unknown. Therefore, we aimed to evaluate the clinical and microbiological efficacy of intravenous Fosfomycin in a tertiary care center.
Methods: The group of adult patients aged 18 years and over who applied to the hospital between January 2018 and December 2022 and were given intravenous fosfomycin therapy for at least 24 hours due to any infection were retrospectively analyzed.
Results: 71 patients were included in our study. The female/male ratio of these patients was 35/36, and the mean age was 61.5±17.0 (18-84). The avarage time to treatment was 10.6 days (11.3-+11.4). 22 patients (31%) from Intensive Care Unit and 49 (69%) patients from other clinics were included in the study. 18 bacteremia (26%), 15 pneumonia (21%), 14 wound infections (19%), 13 ventilator-associated pneumonia (18%), 5 urinary tract infections (UTI) (8%), 4 abdominal infections (6%) and 2 endocarditis (3%). Detected causative microorganisms were 18 carbapenem susceptible Klebsiella pneumoniae (44%), pandrug resistan Klebsiella pneumoniae (17.5%), 5 MRSA (12.5%), 5 pandrug resistan Pseudomonas aerinosa (12%) ,4 Escherichia coli (10%), 1 Acinetobacterbaumanii (2.5%) and 1 Enterobacter spp. (2.5%). Looking at the underlying diseases, one of our patients had diabetes mellitus and another patient had chronic renal failure. Mean procalcitonin (PCT) and C reaktive protein (CRP) (cutoff value0.5 ng/mL) values were 2.53±1.2 ng/ml and 89.7±21.9 mg/dl, respectively. Median sodium (Na), potassium (K), AST, ALT, and creatinine values of the patients before and after fosfomycin IV treatment were calculated and there was no statistically significant difference.
Clinics combined with fosfomycin IV were as follows: 31 meropenem (44%), 15 colistin (26%), 18 tigecycline (26%), 3 vancomycin (4%), 3 amikacin (4%) and 1 daptomycin (1%).
Conclusions: According to the results of our study, it was seen that Fosfomycin is a safe and effective option in the treatment of multidrug-resistant infections. Accordingly, our results are compatible with the literature.

The current study sought to assess the phytochemicals and antimicrobial activities of Psidium guajava Linnaeus leaves extracts. The contents of healthy free fresh leaves of Psidium guajava Linnaeus were analyzed for antibacterial efficacy using dichloromethane (DCM), palm wine, and n-hexane solvents. The presence of several chemical components was revealed by phytochemical analysis of the extracts. The Agar disc diffusion method was used to assess antibacterial activity against five clinically significant organisms. The extract's zone of inhibition against each organism was measured. The presence of phytochemicals such as tannins, terpenoids, flavonoids, alkaloids, and phenol were discovered. Saponin was not found in all of the solvents tested. The antibacterial results showed that the n-hexane fraction had 44mm as zone inhibition against Bacillus subtilis at 25 mg/ml, followed by 42 mm in Escherichia coli at the same concentration, which was significantly higher than the standard amoxicillin at 25 ug. The highest zone of inhibition for DCM fraction was at 25 mg/ml (35 mm) and 10 mg/ml (25 mm) against Pseudomonas aeruginosa and E. coli, respectively, with similar zones of inhibition to the standard. Finally, resistance was observed in P. aeruginosa, but significant inhibition was observed against B. subtilis (30mm), E. coli (15 mm), and S. aureus (15 mm) at 15%. As a result, Psidium guajava leaf extracts contain phytochemicals as well as significant antibacterial properties, particularly against B. subtilis and E. coli, and can be used to obtain useful lead compounds for the eventual synthesis of medicinally significant antioxidant and antibacterial agents.

Published: July 2023

The facial nerve is the main motor nerve that activates the mimic musculature of the face. Nerve tree injuries lead to paralysis of the same half of the face. In addition to functional damage in the form of difficulty in chewing, speaking and closing the eyes, paresis is the cause of pronounced emotional and social problems in patients.

The etiology of facial nerve damage is diverse, including trauma, neurological, infectious, metabolic, vascular, neoplastic processes, as well as idiopathic and iatrogenic. Of special importance to us are iatrogenic injuries of the transcranial part of the facial nerve, which most often occur as part of surgical interventions in the area of the parotid lodge, where the nerve itself branches into its final branches that innervate facial muscles. A high degree of iatrogenic damage over 40% requires the timely application of adequate techniques and materials for the purpose of neuroregeneration.

Considering the delicacy of the function of the facial nerve and the consequences of its damage, previous methods described in some studies, used in the regeneration process are based on the summarized results of experimental studies on different animal models. A prerequisite for the success of an experimental study is certainly the anatomical compatibility of experimental animals and humans.

Based on the analyzed research, in the last decade rats were used the most, which can be linked to acceptable maintenance costs. Nevertheless, rabbits represent an ideal experimental model due to their anatomical and functional similarities with humans, in which it is possible to successfully simulate paralysis of the facial nerve and monitor the recovery of mimic musculature using the method of movement visualization and electromyography.

Stress inevitably occurs during any fish handling and manipulation in culturing, research, or clinical examination situations that require capture and removal of fish from water. Different stress factors can affect the changes in the relative numbers and function of cells of the fish immune system. Catching, transportation and over-crowding caused stress-induced changes in the total number of leukocytes and thrombocytes, as well as changes in the leukocyte formula in Prussian carp (Carassius gibelio, Bloch, 1782) presented here. Cytochemical characterization of leukocyte cell types was performed by applying Myeloperoxidase (MPO), Periodic Acid Schiff (PAS) and Sudan Black B (SBB) staining of Prussian carp blood smears. Cytochemical characterization is a rapid and efficient method for white leukocyte differentiation and insight in their functional status. Comparison and analysis in Prussian carp hematological parameters from fish with and without exposure to stressful conditions such as capture, manipulation, transport and holding, revealed significant differences between stressed and non-stressed fish. Significant reduction in the total number of thrombocytes and lymphocytes and the increase in total neutrophil count were observed in stressed animals. However, differences in total leukocyte number and the number of monocytes were not observed. Deviations from the estimated reference intervals for Prussian carp hematological parameters clearly indicated the presence/absence of a stress reaction and to some extent its intensity. Estimated reference intervals and characterization of morphological and cytochemical appearance of blood cells form a solid basis for further research of the cellular immune function and hematology changes in Prussian carp.

Epidermis stem cells have a crucial role through the processes of proliferation and differentiation, to replace cells that are constantly lost during tissue turnover or following injury. On the other hand, thyroid hormones regulate the proliferation and differentiation of epidermal cells and thus significantly influence the homeostasis of the skin. It is well known that maternal hypothyroidism during pregnancy leads to impaired development of many organ systems in their offspring. However, there is a lack of data about the influence of maternal subclinical hypothyroidism during pregnancy and lactation on the development of the skin and its derivatives in the litter. The aim of this study was to investigate the effects of maternal thyroid dysfunction on the development of the skin and its derivatives in their offspring in the early postnatal period. Antithyroid substance 6-n-propyl-2-thiouracil was added into the drinking water to female Albino Oxfords rats from the beginning of pregnancy and during lactation, with the aim to induce subclinical and overt form of hypothyroidism. Skin samples were taken from male pups within twenty-four hours and seven days after birth. The main findings of this investigation were that both forms of maternal hypothyroidism lead to serious damage of the epidermis in pups in terms of pronounced hyperkeratosis and reduction of the germinal layer along with a reduced number of hair follicles and their delayed morphogenesis. Epidermal impairments were more pronounced in pups with the overt form of hypothyroidism while offspring with the subclinical form had impairments that were less pronounced and delayed in occurrence.

The first few weeks after broilers hatch are the period of most intense bone growth and development, and the time when they are most susceptible to the influence of various external and internal factors. Research in the recent decades has focused on the involvement of melatonin in bone development during early life in chickens. Melatonin release from the pineal gland has a circadian rhythm, with the highest levels circulating during the night and decreasing during the light phase of the day. Various types of lighting are used in intensive broiler production. In this study, the effects of melatonin on the tibial structure and growth of broilers were investigated. During the first two weeks of life, two groups of chickens were kept under continuous light and fed the same diet, with the experimental group receiving melatonin in the amount of 0.03 g/kg of feed. The results obtained showed that the addition of melatonin in the diet had positive effects on the development and growth of the tibia, which was expressed in a significantly greater thickness of the diaphysis and cortical bone of the diaphysis, higher breaking force and higher values of alkaline phosphatase activity. The cortical bone mineral density of the tibia did not differ significantly between the groups of chicken.

Published: July 2023

Hypertrophic osteopathy (HO) is a pathological condition characterized by progressive, bilateral and symmetrical periosteal bone hyperostosis. Hypertrophic osteopathy is considered a secondary disease that occurs as a consequence of many chronic processes, which are primarily localized in the thoracic cavity (intrathoracic lesions), and less as a result of changes in the abdominal cavity (extrathoracic lesions). We describe a case of a 3.5-year-old female unneutered short-haired cat with a history of chronic weight loss, decreased appetite, dyspnea, and wet cough. During the native X-ray examination of the thoracic cavity, a clearly limited homogeneous radiopaque shadow which covered the entire thoracic cavity was found, as well as periostitis of the front limbs, mainly on the humeri, radii and ulnae. After euthanizing the cat, a control X-ray examination and necropsy of the body was performed. The necropsy revealed a soft-tissue proliferation measuring 13 x 5 x 4 cm and weighing 228 g, and a pronounced ossified periostosis of the long bones, while the histopathological findings revealed adenocarcinoma of the lung with metastasis to the mediastinal lymph nodes. The outcome of hypertrophic osteopathy mostly depends on the primary cause. If the initial lesion had been identified and removed on time, the condition would have also receded spontaneously. The primary tool in determining hypertrophic osteopathy is X-ray diagnosis. Considering the determination of this condition is an indicator of ongoing severe disease, especially in the thoracic cavity, its early diagnosis would lead to prolongation of the animal's life.

In Aceh, many referral issues were encountered at the Emergency Department of Dr. Zainoel Abidin Hospital, which categorized the referral patient's condition that was considered to improve clinical care to patients referred. This quantitative study aims to determine the characteristics of patient referral and the referral issues encountered at the Emergency Department of dr. Zainoel Abidin. In total, 1674 patients were recruited using the purposive sampling method from April to June 2019. The results showed that most referral patients arrived at the Dr. Zainoel Abidin Hospital emergency room during the night and very few arrived in the morning. Most patients arriving at the Emergency Department of Dr. Zainoel Abidin Hospital at night were from Aceh Singkil and Gayo Lues. Meanwhile, patients from Aceh Besar, Aceh Jaya, Banda Aceh, Pidie, and Pidie Jaya mostly arrived at the Emergency Department Dr. Zainoel Abidin Hospital during the afternoon. Most patients from Sabang and Simeulu came in the morning. The most commonly referred patients were adult and elderly patients, aged 46-65 years. Most of the patients had been treated in the daycare unit at the previous hospitals with the longest hospital stay was 36 days before being referred to Dr. Zainoel Abidin Hospital. Head injuries and strokes were the most frequent diagnosis led to Emergency Department Dr. Zainoel Abidin Hospital. Furthermore, our study found that 51% of the referral care system issue was that the patient did not arrive at the Emergency Department of Dr. Zainoel Abidin Hospital after being confirmed to be referred through telephone.

The data were presented in percentage (%). A total of 100 respondents were included comprising 54.0% female and most of the respondents aged between 60–64 years (43.0%). The largest percentage of the participants made their own herbal medicines (45.0%) and used them routinely as a habit (36.0%). About 75.0% of the elderly felt better and almost all of them (96.0%) reported no adverse reaction following herbs consumption. A total of 39 plant species were used by the respondents with Annona muricate L. was the most frequently used medicinal plant (16.0%) and leaves were the most commonly used parts (68.4%). Most of the herbs were prepared through boiling and squeezing (32.6%), and mainly used in the form of a drink (77.3%). Cough treatment with herbs made up 19.3%, followed by hypertension (18.0%), flatulence (7.6%), dyspepsia (5.8%), and fever (5.8%). Our investigation revealed consistency in the use of some medicinal herbs in the present study with published experimental data. However, since elderlies are often considered vulnerable individuals, the practice of herbal self-remedies among this population should be well-monitored.

Kebudayaan tidak terlepas dari pengaruh agama. Hal itu berlaku pula bagi kebudayaan Indonesia masa HinduBuddha. Studi ini meneliti relief Yeh Pulu dari sudut pandang agama Hindu. Penelitian ini bertujuan untuk mengkaji sistem religi dan mengungkap makna yang terkandung dalam pahatan relief Yeh Pulu. Studi ini dilakukan dengan cara mengunjungi langsung ke Situs Yeh Pulu, lalu dilakukan pengamatan, pencatatan, dan pengambilan gambar. Data dianalisis mengunakan analisis kontekstual dan komparatif. Hasil penelitian menunjukkan bahwa relief Yeh Pulu memiliki sembilan panil relief yang menggambarkan berbagai aktivitas kehidupan masa lalu. Terdapat empat komponen sistem religi yang terkandung dalam rangkaian relief Yeh Pulu. Pertama, konsepsi ketuhanan diwujudkan dengan penggambaran tokoh Ganesha dan Krsna (Avatara Wisnu). Kedua, tokoh dan umat agama sejumlah 18 tokoh dengan rincian 12 laki-laki dan 6 perempuan. Ketiga, indikasi adanya upacara agama disimbolkan dengan keberadaan kendi yang keluar asapnya. Jenis upacara yang dilakukan adalah pemujaan terhadap para dewa, pendirian bangunan suci, penyucian bangunan suci, pemberian persembahan kepada rsi, dan praktik tantrayana. Keempat, sarana keagamaan yang digunakan adalah kendi, buyung, kayu/bambu, cangkul, tombak, tali, dan tongkat yang ujungnya seperti mangkuk. Makanan yang disajikan terbuat dari bahan tanaman dan hewan buruan. Makna yang terkandung dalam ukiran relief Yeh Pulu adalah siklus kehidupan, kegiatan keagamaan, kesuburan, dan keragaman.

El caudal mínimo hidrológico es un parámetro de importancia para la gestión del recurso hídrico y su determinación se efectúa según un cuidado análisis que combina características físicas (profundidad, velocidad y sustrato); químicas (temperatura, oxígeno disuelto, pH,conductividad), y biológicas. Los métodos con enfoques estadísticos sonuna opción para considerar como primera aproximación en regionesdonde los datos de caudal son pocos debido a su falta de medición o porsu escaso periodo de cobertura. El Río Dulce es el principal tributario a la laguna Mar Chiquita, un importante ecosistema de gran escala ubicada entre las provincias de Córdoba y Santiago del Estero―región central de Argentina― y quedurante los últimos 20 años presentó una variación de superficie de 6 550a 2 500 km² entre los años 2003 y 2014. El objetivo principal fue aplicar en secciones de interés métodoshidrológicos con enfoque estadístico para analizar y aproximar los caudales mínimos necesarios del Río Dulce. Para ello se utilizaron seriesde caudal en periodos posteriores a la construcción de las principalesobras de regulación en la cuenca, a fin de considerar la variación delrégimen natural del río por la ejecución de las mismas. Estos novedososresultados de caudal mínimo hidrológico se presentan mediante un índicemínimo hidrológico anual, y por una variación mensual del caudal definidacomo régimen de caudales

El uso de imágenes de radar de apertura sintética (SAR) representa unafuente valiosa de información para caracterizar regiones geográficas susceptibles de inundaciones, como en el sureste de México, ya que éstas no son sensibles a condiciones de nubosidad y/u oscuridad. En estainvestigación se presenta una metodología para identificar cuerpos de agua en una región del sureste de México. Se aplicaron tres algoritmosde aprendizaje automático: bosque aleatorio (RF), potenciación delgradiente (GB) y máquina de soporte vectorial (SVM) para clasificar las tres clases objetivo A: agua, áreas inundadas y cuerpos de agua; I: infraestructura urbana y/o suelo desnudo, y V: vegetación a partir de imágenes SAR. La imagen SAR utilizada cubre una zona geográficaproyectada UTM Zona 15 Norte WGS84, localizada en los estados de Tabasco y Chiapas, la cual fue preprocesada para disminuir errores en la imagen. Los modelos RF, GB y SVM se implementaron en lenguaje Python,que fueron entrenados y probados en predicción a partir de una base de datos de 12 000 muestras, con valores de amplitud de la imagen SAR. El modelo RF obtuvo una precisión global de clasificación (푃푃푃푃) de 0.979(+/-0.003); GB obtuvo푃푃푃푃= 0.979(+/-0.003), y SVM푃푃푃푃 = 0.974(+/-0.005).Los tres modelos obtuvieron un valor de F1_score superior a 0.99 parapredecir la clase A; el clasificador RF obtuvo valores de 퐴퐴퐴퐴퐴퐴 = 1 para las tres clases objetivo evaluadas. Este estudio permite mostrar el uso potencial de las imágenes satelitales SAR y el alto desempeño de los modelos de aprendizaje automático RF, GB y SVM para clasificar e identificar los cuerpos de agua, así como resaltar su importancia en estudios de los posibles impactos de las inundaciones

La obtención de patrones de distribución temporal de la lluvia mediante curvas de masa sintéticas o hietogramas es un recurso aplicado a nivel internacional para elaborar la tormenta de diseño. En el presente artículo se realizó un análisis de 243 eventos lluviosos convectivos de más de 25 mm ocurridos en la estación meteorológica Yabú de la provincia Villa Clara, Cuba, en el periodo comprendido desde 1989 hasta 2019, con el objetivo de elaborar los hietogramas sintéticos característicos de la estación mediante el método de Huff. Se categorizaron las lluvias y se identificaron tres tipos SC-T1, SC-T2, SC-T3 de acuerdo con la relación entre el tiempo de duración del aguacero y el tiempo donde ocurren las mayores intensidades. Las curvas de masa obtenidas para cada probabilidad de ocurrencia se expresaron en hietogramas adimensionales, los cuales fueron ajustados a los modelos paramétricos de Sherman, Wenzel y uno propio elaborado por los autores, que describen la distribución de las intensidades con respecto al tiempo. Este resultado permitió obtener las curvas de intensidad-frecuencia-duración para cada tipo de aguacero, y cada probabilidad de ocurrencia. Se lograron elevados coeficientes de correlación de Pearson y el modelo elaborado por los autores mostró el mejor desempeño. Los resultados indican que los hietogramas adimensionales obtenidos reflejan satisfactoriamente el fenómeno de lluvias convectivas en la localidad de estudio
