Foreign bodies in the bladder are a rare but significant medical condition that can lead to complications and severe health consequences. While it can be challenging to access the bladder, foreign bodies can occasionally find their way inside. These objects may be intentionally introduced, as in cases of self-insertion or insertion by others, or may enter the bladder accidentally, as in cases of migration from adjacent organs or tissues.Various objects have been found in the bladder, including but not limited to electric cables, pencils, catheters, aluminum braids, and removable parts of medical cystoscopy equipment. In addition, unusual objects such as candles, pens, thermometers, and other household items have been reported. Patients who insert foreign bodies into the bladder may have underlying psychological disorders or curiosity, while accidental insertion may occur due to medical procedures, trauma, or other causes. (A W Badenoch)Complications associated with foreign bodies in the bladder can be acute or chronic and may include pain, infection, inflammation, hematuria, urinary retention,bloody urine or urinary tract obstruction. Patients may present with various symptoms, including dysuria, frequency, urgency, or incontinence. Diagnosing foreign bodies in the bladder is typically done through imaging studies, such as X-rays or ultrasound, and confirmed by cystoscopy.In some cases, foreign bodies in the bladder may be discovered incidentally during medical interventions for other conditions. For example, the discovery of a post-osteosynthesis bolt in the urinary bladder, as in the case presented in this report, is a rare finding that may be associated with asymptomatic conditions and tissue formation of the bladder. The prompt and appropriate management of foreign bodies in the bladder is critical to prevent serious complications and improve patient outcomes.

Kutane Infektionen im Kindesalter
Authors: Fölster-Holst Regina 
Published: July 2023

ZusammenfassungKutane Infektionen bei Kindern sind häufig, wobei als Auslöser Bakterien, Viren oder Pilze in Betracht kommen. Diese können die epidermalen Zellen direkt von außen oder im Rahmen von systemischen Erkrankungen infizieren, die Hautreaktionen können aber auch durch die Toxinfreisetzung der Bakterien oder als Antwort des Immunsystems auf die Infektionserreger erklärt werden. Beispiele dafür sind das Staphylococcal scalded skin syndrome (SSSS) und Scharlach sowie Exanthemerkrankungen. Darüber hinaus treten sekundäre Infektionen häufig bei Parasitosen auf. Der Artikel fokussiert bakterielle, mykotische und virale Infektionen, wobei bei den letzteren auch Exanthemerkrankungen Erwähnung finden. Aufgrund des umfangreichen Themas, das den Rahmen dieses Heftes sprengen würde, werden nur häufig vorkommende bakterielle, virale und mykotische Hautinfektionen fokussiert und die Exanthemerkrankungen sowie die Parasitosen lediglich tabellarisch dargestellt. Detailliertere Abhandlungen sind entsprechenden angegebenen Referenzen zu entnehmen.

Authors: Aleem Benish , Shafi Afshan , Hameed Abdul , Aleem Fatima 
Published: July 2023

Objective: To determine the association between inflammatory mast cells and various diseases of the salivary glands.
Material and Methods: An experimental lab based descriptive study was done at the institute of pathology at diagnostic medicine, Khyber medical university, Peshawar. Non probability, convenient sampling comprising of n=71was done and tissue biopsies of salivary gland diseases were collected from April, 2022 to Sept. 2022. Gross examination, followed by tissue processing and routine Hematoxylin and Eosin staining was done. Giemsa stain was done to visualize the inflammatory mast cell population, microscopically. Mast cell count at the invasive site of the tumor within the underlying connective tissue/ lamina propria as well as intra-tumoral stromal tissue was calculated and recorded in peri- and intra-tumor stromal fields.
Result: It was found that out of all the 71 included cases 24% were non-neoplastic and 76% were neoplastic lesions. The mean age of affected patients is around 47.5 years while the male to female ratio is 1.4:1. Mucocele was the most prevalent non neoplastic lesion while adenoid cystic carcinoma was found to be the most commonly encountered malignancy. Mast Cell count was almost the same for peri-tumoral and intra-lesional areas of benign salivary gland tumours. It was significantly high in malignant tumours such as mucoepidermoid carcinoma.
Conclusion: Mast cell may serve as a potential cause for varying degree of inflammatory response in case of neoplastic salivary gland lesions.

Authors: Gonzalez-Asenjo David , Izquierdo Luis R. , Sedano Javier 
Published: July 2023

Purpose: Define a simple and efficient method to allocate costs and benefits in energy communities, and characterize some of its key properties.Design/methodology/approach: The approach is theoretical. We define an algorithm to allocate costs and benefits in energy communities, and derive some of its formal properties using mathematical reasoning. We also compare the proposed algorithm with several alternatives.Findings: The proposed algorithm is simple and it ensures that the resulting distribution of costs and benefits is (i) beneficial for every member of the community, (ii) efficient, (iii) fair (in a formally defined sense), (iv) smooth (small changes in the consumption or in the generation of energy cannot lead to big changes in the allocation of costs and benefits), and (v) environmentally friendly in the sense that the individual allocated cost is a strictly increasing function of individual consumption.Research limitations/implications: The properties of the proposed algorithm are satisfied for a specific type of energy community that is defined in the manuscript. Practical implications: The algorithm is easy to implement in any energy community.Social implications: The algorithm is highly relevant for any community of prosumers who are willing to exchange energy internally. It guarantees a number of desirable properties that are formally defined in the paper.Originality/value: We prove that a simple algorithm to allocate costs and benefits in energy communities guarantees the fulfilment of several desirable properties.

Published: July 2023

The current study, “Development and nutritional evaluation of khoa fortified with jamun seed (Syzygium cumini L.) Powder," was carried out in Vadodara, Gujarat, India during the year 2022 in the Product Development Laboratory of the Department of Food Technology, Parul Institute of Applied Sciences, Parul University. Khoa is an Indian traditional dairy product which is fortified with jamun seed powder. The nutritional evaluation of khoa fortified with jamun seed is done by analyzing nutrient content. Jamun seed powder is a popular detoxifying herb because it contains ash, moisture, crude protein, fat and fiber. The average proximate constituents such as moisture, carbohydrate, protein, fat, fiber and ash content were determined in khoa as follows (45.8%), (75.15%), (17.2%), (2.81%), (1.84%) and (3%) respectively. The minerals determined were calcium (40.87mg), iron (0.65mg), magnesium (10.38mg) and zinc (< 2.0mg) respectively. The Fourier transform infrared spectroscopy (FT-IR) of khoa showed the presence of spectra 2858.52 cm-1 which represents Carbonyl group, 1743.30 cm-1 which represents Hydrocarbon group, 1542.79 cm-1 which represents presence of CONH group and 1029.13 cm-1 which represents OH group. Minerals such as calcium, magnesium, iron and zinc of khoa were evaluated. The total energy value of khoa was observed as 310.01 Kcal/100gm. Then the khoa was packed in polyethylene pouches (PEP) and stored under ambient (25-28 o C) and refrigerated (4oC) temperature conditions for 7 days and it was observed that during the storage study of khoa, at ambient temperature the overall increase in moisture content of khoa ranged from (45.8%) to (47.1%) whereas, the overall decrease in protein, fat and ash ranged from (17.2%) to (16.1%), (2.81%) to (2.58%) and (3%) to (2.3%), respectively. During the storage study of khoa at refrigeration temperature we observed that the overall increase in moisture content of khoa ranged from (45.8%) to (46.4%) whereas, the overall decrease in protein, ash and fat ranged from (17.2%) to (16.3%), (3%) to (2.6%) and (2.81%) to (2.75%), respectively. The Moisture increases more at ambient temperature as compared to refrigeration temperature. Whereas the overall decrease in protein, ash and fat is more in ambient temperature compare to refrigeration temperature. Thus, the developed khoa have improved nutritional value and is suggested to diabetic patients.

AbstractSmall‐scale robots capable of remote active steering and navigation offer great potential for biomedical applications. However, the current design and manufacturing procedure impede their miniaturization and integration of various diagnostic and therapeutic functionalities. Herein, submillimeter fiber robots that can integrate navigation, sensing, and modulation functions are presented. These fiber robots are fabricated through a scalable thermal drawing process at a speed of 4 meters per minute, which enables the integration of ferromagnetic, electrical, optical, and microfluidic composite with an overall diameter of as small as 250 µm and a length of as long as 150 m. The fiber tip deflection angle can reach up to 54o under a uniform magnetic field of 45 mT. These fiber robots can navigate through complex and constrained environments, such as artificial vessels and brain phantoms. Moreover, Langendorff mouse hearts model, glioblastoma micro platforms, and in vivo mouse models are utilized to demonstrate the capabilities of sensing electrophysiology signals and performing a localized treatment. Additionally, it is demonstrated that the fiber robots can serve as endoscopes with embedded waveguides. These fiber robots provide a versatile platform for targeted multimodal detection and treatment at hard‐to‐reach locations in a minimally invasive and remotely controllable manner.
Patterning Complex Line Motifs in Thin Films Using Immersion‐Controlled Reaction‐Diffusion

Published: July 2023

AbstractThe discovery of self‐organization principles that enable scalable routes toward complex functional materials has proven to be a persistent challenge. Here, reaction‐diffusion driven, immersion‐controlled patterning (R‐DIP) is introduced, a self‐organization strategy using immersion‐controlled reaction‐diffusion for targeted line patterning in thin films. By modulating immersion speeds, the movement of a reaction‐diffusion front over gel films is controlled, which induces precipitation of highly uniform lines at the reaction front. A balance between the immersion speed and diffusion provides both hands‐on tunability of the line spacing () as well as error‐correction against defects. This immersion‐driven patterning strategy is widely applicable, which is demonstrated by producing line patterns of silver/silver oxide nanoparticles, silver chromate, silver dichromate, and lead carbonate. Through combinatorial stacking of different line patterns, hybrid materials with multi‐dimensional patterns such as square‐, diamond‐, rectangle‐, and triangle‐shaped motifs are fabricated. The functionality potential and scalability is demonstrated by producing both wafer‐scale diffraction gratings with user‐defined features as well as an opto‐mechanical sensor based on Moiré patterning.
Helical Polycyclic Heteroaromatic as Hole Transport Material for Perovskite Solar Cell: Remarkable Impact of Alkyl Substitution Position

Published: July 2023

AbstractPolycyclic aromatic hydrocarbons play a critical role in the development of organic semiconductors. This study unravels the impact of alkyl substitution position on the molecular energy level, glass transition temperature, diffusion of external species, and hole transport of a pyrrole‐rich, helical polycyclic heteroaromatic, that is TBPC. Compared to terminal substitution, internal hexyl substitution results in steric repulsion with TBPC, weakening π─π stacking and therefore improving thin film morphology. Internal substitution also reduces energy disorder, lowers reorganization energy, and increases intermolecular transfer integrals, leading to enhanced hole mobility. Notably, the organic semiconductor with internal hexyl substitution (TBPC‐611) exhibits a higher molecular packing density, resulting in a markedly higher glass transition temperature and slower diffusion of external species. Using TBPC‐611 as the hole transport material, this work successfully fabricates perovskite solar cells with an average power conversion efficiency above 24%, showing good photostability and thermostability. These findings contribute new insights to the development of high‐performance organic semiconductors.
