Abstract
The water quality in Karachi (Pakistan) is uncertain due to the occurrence of fungi and other microorganisms. A total of twenty-five water samples were collected from public places, educational institutes, hospitals, water supply systems and surface water of the canal of Karachi (Pakistan). The different fungal species including Acremonium sp., Alternaria alternata, Aspergillus flavus, A. fumigatus, A. sulphureus, Cladosporium sp., Fusarium sp., Clonostachys (Gliocladium) sp., Macrophomina phaseolina, Mucor racemosus, Paecilomyces sp. Penicillium chrysogenum, P. citrinum, P. commune, P. expansum, Rhizoctonia sp. and Stachybotrys sp. were isolated from these drinking water samples. However, the bacteria, microalgae and some other microorganisms were present in low concentrations. The reason for fungi infection and production of mycotoxicity depends upon various factors and the availability of their nutrients in filtration plants. The major threats to human health are fungal mycotoxicity which is responsible for carcinogenic and other lethal diseases. Mostly, the genus Aspergillus was dominated and isolated with a maximum of 88-98% of occurrence in the different samples of drinking water by the direct plate-spread method. For the control of fungi, various Physico-chemical coagulation treatments were used, but Potassium alum, clay pot, and hot water treatment disinfected effectively 69-70% removal of the fungi and its spore or mycelia from the water. In addition, it is concluded that drinking water purifications such as chlorination, filtration and lime did not eliminate thermophilic fungal spores or mycelia including Penicillium, Paecilomyces and Mucor from the water.

Abstract
Introduction The utilization of fauna and fauna-based byproducts in ethnomedicinal usages has been a longstanding human activity, practiced across various cultures worldwide. This study focuses on investigating the utilization of animal-based traditional medicine by the people of Pakistan, specifically in the Gujranwala area. Methods Data collection took place from January to September 2019 through interviews with local communities. Ethnomedicinal applications of animal products were analyzed using several indices, including Relative Frequency of Citation (RFC), Relative Popularity Level (RPL), Folk Use Value (FL), and Relative Occurrence Percentage (ROP). Results The study identified the use of different body parts of 54 species of animals in treating various diseases and health issues. These include but are not limited to skin infections, sexual problems, pain management (e.g., in the backbone and joints), eyesight issues, immunity enhancement, cold, weakness, burns, smallpox, wounds, poisoning, muscular pain, arthritis, diabetes, fever, epilepsy, allergies, asthma, herpes, ear pain, paralysis, cough, swelling, cancer, bronchitis, girls' maturity, and stomach-related problems. Certain species of fauna were noted by informers with high "frequency of citation" (FC), ranging from 1 to 77. For instance, the black cobra was the most frequently cited animal for eyesight issues (FC = 77), followed by the domestic rabbit for burn treatment (FC = 67), and the Indus Valley spiny-tailed ground lizard for sexual problems (FC = 66). Passer domesticus and Gallus gallus were noted to have the highest ROP value of 99. Discussion The findings of this study provide valuable preliminary insights for the conservation of fauna in the Gujranwala region of Punjab, Pakistan. Additionally, screening these animals for medicinally active compounds could potentially lead to the development of novel animal-based medications, contributing to both traditional medicine preservation and modern pharmaceutical advancements.

Abstract
Abstract A socio-economic study was conducted in district Mardan of the Khyber Pakhtunkhwa (KP) province of Pakistan to get a comprehensive knowledge of the agroforestry tree species grown on the farmlands, their yield, and carbon stock. For yield and carbon stock estimation, data were collected from 59 sample plots by measuring the diameter, height, volume, and biomass of selected agroforestry tree species through D-tape and Haga altimeter. A total of 59 sample plots were inventoried using 2.5 percent sampling intensity. Each sample plot has an area of 0.5 ha, where each tree with a Diameter at Breast Height (DBH) ≥ 5 cm was inventoried. The calculated amount of volume of each tree species was then converted to biomass by multiplying it by the density of wood and the Biomass Expansion Factor (BEF). Total yield and C stock for the selected agroforestry tree species were 11535.2 metric tons and 2102.2 metric tons, respectively. Populus euroamericana is classified as the main tree with 28% growing stock prior to Morus alba by 21%, while Melia azedarach, Eucalyptus camaldulensis, Dalbergia sissoo, Acacia nilotica, Salix tetrasperma, and Bombax ceiba consist of 15%, 12%, 8%, 6%,7% and 3% growing stock respectively. Among the species found in different sampling plots the yield of Populus euroamericana was found to be 4747.5 metric tons and it was followed by the species Morus alba found at 2027.3 metric tons. Similarly, the volume for Melia azedarach, Eucalyptus camaldulensis, Dalbergia sissoo, Salix spp, Boombox ceiba, and Acacia nilotica was 1532.2 tons,1503 ton,745.7,203.5ton, 555.4ton and 220.5ton, respectively. The carbon stock for Populus euroamericana was calculated as 777.8 ton/ha, while for Eucalyptus camaldulensis, Melia azedarach, Morus alba, Dalbergia sissoo, Acacia nilotica, Salix species, and Bombax ceiba it was calculated as 312.3ton/ha, 272.1ton/ha, 363ton/ha, 245.1ton/ha, 51.4ton/ha, 27.3ton/ha and 53.2ton/ha, respectively. The questionnaire survey conducted for price dynamics showed that the majority of respondents purchase timber from the market for construction. But they use farm trees with low-quality city construction. They dislike using local timber in the conventional building as timber from farm trees is liable to insect attack. Rs. 50,000-100000, (33.33%) of daily sales was concluded from 50% of the trader while (16.7%) of the traders have their sales between Rs.150,000-200,000. Therefore, it is concluded by the authors that both provincial and federal government should promote agroforestry in Pakistan through different incentives because it has the potential to cope with dilemma of deforestation of natural forests and improve the livelihood of local peoples. It is strongly recommended that special projects just like the Ten Billion Tree Afforestation Project (T-BTTP) should be launched for agroforestry plantation and promotion in the country to sustain the ecological harmony and uplift the socio-economic condition of the peoples of Pakistan.

Abstract
BACKGROUND The present study was conducted to explore the diversity pattern of spring vegetation under the influence of topographic and edaphic variables in sub-tropical zone, District Malakand. In the present vegetation study, 252 species of 80 families were recorded in the study area. It included 39 species of trees, 43 species of shrubs, 167 species of herbs and 3 climber species. As a whole, 12 communities were established on the basis of topographic and edaphic characteristics in 12 different stations. RESULTS The results of the present study revealed that all diversity indices (species diversity, evenness index, species richness index, maturity index) during spring showed that the communities in plains lying at lower altitudes had higher diversity while the communities formed at high altitudes had lower diversity. The results of the similarity index showed that there was low similarity (below 50%) amongst the communities in different stations. CONCLUSIONS It can be concluded that variations in topographic and edaphic factors affect species diversity and communities pattern.

Abstract
Rapidly rising population and climate changes are two critical issues that require immediate action to achieve sustainable development goals. The rising population is posing increased demand for food, thereby pushing for an acceleration in agricultural production. Furthermore, increased anthropogenic activities have resulted in environmental pollution such as water pollution and soil degradation as well as alterations in the composition and concentration of environmental gases. These changes are affecting not only biodiversity loss but also affecting the physio-biochemical processes of crop plants, resulting in a stress-induced decline in crop yield. To overcome such problems and ensure the supply of food material, consistent efforts are being made to develop strategies and techniques to increase crop yield and to enhance tolerance toward climate-induced stress. Plant breeding evolved after domestication and initially remained dependent on phenotype-based selection for crop improvement. But it has grown through cytological and biochemical methods, and the newer contemporary methods are based on DNA-marker-based strategies that help in the selection of agronomically useful traits. These are now supported by high-end molecular biology tools like PCR, high-throughput genotyping and phenotyping, data from crop morpho-physiology, statistical tools, bioinformatics, and machine learning. After establishing its worth in animal breeding, genomic selection (GS), an improved variant of marker-assisted selection (MAS), has made its way into crop-breeding programs as a powerful selection tool. To develop novel breeding programs as well as innovative marker-based models for genetic evaluation, GS makes use of molecular genetic markers. GS can amend complex traits like yield as well as shorten the breeding period, making it advantageous over pedigree breeding and marker-assisted selection (MAS). It reduces the time and resources that are required for plant breeding while allowing for an increased genetic gain of complex attributes. It has been taken to new heights by integrating innovative and advanced technologies such as speed breeding, machine learning, and environmental/weather data to further harness the GS potential, an approach known as integrated genomic selection (IGS). This review highlights the IGS strategies, procedures, integrated approaches, and associated emerging issues, with a special emphasis on cereal crops. In this domain, efforts have been taken to highlight the potential of this cutting-edge innovation to develop climate-smart crops that can endure abiotic stresses with the motive of keeping production and quality at par with the global food demand.

Abstract
Numerous investigations on plant ethnomedicinal applications have been conducted; however, knowledge about the medicinal use of wild animals is still limited. This present study is the second on the medicinal and cultural meaning of avian and mammalian species used by the population in the surrounding area of the Ayubia National Park, KPK, Pakistan. Interviews and meetings were compiled from the participants (N = 182) of the study area. The relative frequency of citation, fidelity level, relative popularity level, and rank order priority indices were applied to analyze the information. Overall, 137 species of wild avian and mammalian species were documented. Of these, 18 avian and 14 mammalian species were utilized to treat different diseases. The present research showed noteworthy ethno-ornithological and ethno-mammalogical knowledge of local people and their connection with fauna, which might be useful in the sustainable utilization of the biological diversity of the Ayubia National Park, Khyber Pakhtunkhwa. Furthermore, in vivo and/or in vitro examination of the pharmacological activities of species with the highest fidelity level (FL%) as well as frequency of mention (FM) might be important for investigations on faunal-based new drugs.

Abstract
This research aims to assess the urban growth and impact on land surface temperature (LST) of Lahore, the second biggest city in Pakistan. In this research, various geographical information system (GIS) and remote sensing (RS) techniques (maximum likelihood classification (MLC)) LST, and different normalized satellite indices have been implemented to analyse the spatio-temporal trends of Lahore city; by using Landsat for 1990, 2004, and 2018. The development of integrated use of RS and GIS and combined cellular automata-Markov models has provided new means of assessing changes in land use and land cover and has enabled the projection of trajectories into the future. Results indicate that the built-up area and bare area increased from 15,541 (27%) to 23,024 km2 (40%) and 5756 km2 (10%) to 13,814 km2 (24%). Meanwhile, water area and vegetation were decreased from 2302 km2 (4%) to 1151 km2 (2%) and 33,961 km2 (59%) to 19,571 km2 (34%) respectively. Under this urbanization, the LST of the city was also got affected. In 1990, the mean LST of most of the area was between 14 and 28 ℃, which rose to 22-28 ℃ in 2004 and 34 to 36 ℃ in 2018. Because of the shift of vegetation and built-up land, the surface reflectance and roughness of each land use land cover (LULC) class are different. The analysis established a direct correlation between Normalized Difference Water Index (NDWI), Normalized Difference Vegetation Index (NDVI) with LST and an indirect correlation among Soil Adjusted Vegetation Index (SAVI), Normalized Difference Built-up Index (NDBI), and Built-up Index (BI) with LST. The results are important for the planning and development department since they may be used to guarantee the sustainable utilization of land resources for future urbanization expansion projects.

Abstract
For millennia, ethnic knowledge has been intricately tied to local biodiversity and woven into the fabric of rural communities. Growing scientific evidence suggests that merging ethnic knowledge with new scientific findings can lead to socially acceptable and environmentally friendly approaches essential for the long-term prosperity of local communities. In the high-altitude region, where livestock raising is a key income source, and plant-based utilization for ethno-veterinary practices is widely practiced. In this context, this study was conducted with the aim of documenting the ethno-veterinary use of plant resources in different bio-geographical regions of Jammu and Kashmir's Himalayas (J & KH). Semi-structured interviews and group discussions were used to collect information. Principal component analysis (PCA) and Pearson correlation were conducted to analyze the data. We documented 148 species from 53 families that locals used for various purposes: medicine, fodder, tonic, antidote, magic, and also used to protect themselves from ectoparasite such as Pediculus humanus capitis by the local inhabitants. There were significant differences in the relative usage of plant resources across the three biogeographic regions. Comparatively, the highest number (41%) of plant species were used for ethnoveterinary in the Jammu region, while the lowest number (28%) of species were used in Kashmir. Across the regions, Kashmir and Jammu had the highest level of species similarity (17%), while Jammu and Ladakh had the lowest (1%). A cross-regional assessment of plant resources revealed that 18% of plants were shared among the regions. The reported use of Amaranthus blitum, Morus alba, Ficus palmata, Vitex negundo, Juniperus semiglobosa, Ulmus wallichiana, and Rumex nepalensis are novel for the ethno-veterinary uses of this part of the Himalayan region. The various dry unique traditional fodder preparations (gaaslov, gass khor, pan baath, kaandbaath, Lovgooad, Karb, and Phungma) from plant resources are reported for the first time from the Himalayan region and can be ascribed to the novelty of this study. Plant resources were not only a source of fodder and medicine but also presented themselves as an opportunity for livelihood generation. Therefore, our findings bridge the knowledge gap by documenting key ethnoveterinary applications of native plant species from the study region that are used to cure livestock diseases and disorders by the mountain inhabitants.

Abstract
This article describes the environmental impacts of producing a single seedling in forest nurseries of selected districts (i.e., Haripur, Abbottabad, and Mansehra) of Hazara Division of Khyber Pakhtunkhwa, Pakistan using the life cycle assessment (LCA) approach. This study was based on the cradle-to-gate approach which begins with the pre-nursery stage and progresses toward the main nursery before transplanting seedlings into the plantation site. Data or life cycle inventory (LCI) of seedling production were collected through questionnaire surveys and personal meetings with forest nurseries managers and workers regarding consumption of different inputs such as electricity, diesel, fertilizers, herbicides, and polyethylene bags, organic manure, and water consumption. The SimaPro software version 8.5 and the CML2000 v2.05 environmental model was applied to perform life cycle impact assessment (LCIA) for a single seedling production in forest nurseries in the study area. In line with the objectives of the study, primary data regarding inputs and outputs of the nurseries were collected from 35 nurseries in the study area by using a random questionnaire method. In addition, secondary data were taken from online databases such as Eco-invent v.3.2 CORRIM and peer-reviewed published literature. For this study, a functional unit of a single seedling was considered. Production weighted average data were modeled in the latest environmental modeling software i.e., SimaPro v.8.5 for ten US-EPA most wanted environmental impacts, such as global warming potential (GWP), abiotic depletion (AD), eutrophication potential (EP), acidification potential (AP), freshwater aquatic eco-toxicity (FAE), marine water eco-toxicity (MWE), terrestrial eco-toxicity (TE), ozone layer depletion (OLD), photochemical oxidation (PO), and human toxicity (HT). The results showed that the highest environmental impact posed by a single seedling was marine aquatic eco-toxicity (11.31360 kg 1,4-DB eq), followed by global warming potential (0.02945 kg CO2 eq) and (0.01227 kg 1,4-DB eq) human toxicity. The primary reason for these environmental burdens was the use of synthetic fertilizers in forest nurseries and the consumption of fossil fuels in nursery mechanization and transportation activities. The total cumulative energy demand for a single seedling was (0.800 MJ) with more than 90% contribution from fossil fuel energy resources such as petrol and diesel. It is therefore highly recommended to use renewable energy resources and organic fertilizers instead of chemical fertilizers in forest nurseries to avoid and minimize greenhouse gas emissions (GHS) and other toxic emissions in the study area.

Abstract
BACKGROUND An adequate bowel preparation prior to colonoscopy is a major quality-limiting factor that determines both the diagnostic and therapeutic yield of a colonoscopy. Colonoscopy is considered the gold standard for colon cancer screening and it is the primary approach to the workup of hematochezia, diarrhea and iron deficiency anemia (IDA). Several modifiable factors of bowel prep adequacy have been identified, that account for around 25% of inadequate bowel preparations in outpatient colonoscopies. However, the literature is sparse when examining the factors associated with inadequate preparations and procedure cancellations in an inpatient hospital setting. We aim to identify factors that affect bowel preparation adequacy and procedure cancellations among diagnostic colonoscopies performed during hospitalization. METHODS We retrospectively reviewed the electronic medical records of 1,500 consecutive patients who had a diagnostic colonoscopy as an inpatient at a tertiary level hospital over a 2-year period. All patients were administered a clear liquid diet the day prior to the colonoscopy. Patients were then instructed to drink 4 L of polyethylene glycol (PEG, Golytely) between 5 am to 9 am on the day of the procedure. The clinical course of each case was followed to identify quality of preparations, cancelled procedures and the reasons for cancellations. We applied univariate and multivariate logistic regression analysis to identify variables to predict cancellation and poor preparation. RESULTS A total of 1,029 patients were included in the study. 194 (18.8%) patients had colonoscopy cancellations and 268 (26.0%) had poor bowel preparations. Multivariate analysis revealed these factors to be associated with colonoscopy cancellations: education at the graduate school level [odds ratio (OR) =1.93, P=0.04], Hispanic ethnicity (OR =0.47, P<0.01), hemoglobin level <10 g/dL (OR =1.41, P=0.05) and if the colonoscopy was done for other indications (OR =0.53, P=0.04). Factors associated with poor bowel preparation on multivariate analysis, were dementia (OR =2.44, P=0.02), gastroparesis (OR =3.97, P=0.01) and inpatient opioids use (OR =1.69, P=0.04). CONCLUSIONS The rate of colonoscopy cancellations and poor bowel preparations in inpatient colonoscopies were high, and we were able to identify predictors of inadequate colon preparation and procedure cancellations. Exploring more individualized colon preparation regimens based on personal risk factors could reduce the number of inadequate and cancelled colonoscopies in an inpatient setting.

Abstract
BACKGROUND & AIMS Corticosteroids are the only effective therapy for severe alcohol-associated hepatitis (AH), defined by a model for end-stage liver disease (MELD) score >20. However, there are patients who may be too sick to benefit from therapy. Herein, we aimed to identify the range of MELD scores within which steroids are effective for AH. METHODS We performed a retrospective, international multicenter cohort study across 4 continents, including 3,380 adults with a clinical and/or histological diagnosis of AH. The main outcome was mortality at 30 days. We used a discrete-time survival analysis model, and MELD cut-offs were established using the transform-the-endpoints method. RESULTS In our cohort, median age was 49 (40-56) years, 76.5% were male, and 79% had underlying cirrhosis. Median MELD at admission was 24 (19-29). Survival was 88% (87-89) at 30 days, 77% (76-78) at 90 days, and 72% (72-74) at 180 days. A total of 1,225 patients received corticosteroids. In an adjusted-survival-model, corticosteroid use decreased 30-day mortality by 41% (hazard ratio [HR] 0.59; 0.47-0.74; p <0.001). Steroids only improved survival in patients with MELD scores between 21 (HR 0.61; 0.39-0.95; p = 0.027) and 51 (HR 0.72; 0.52-0.99; p = 0.041). The maximum effect of corticosteroid treatment (21-30% survival benefit) was observed with MELD scores between 25 (HR 0.58; 0.42-0.77; p <0.001) and 39 (HR 0.57; 0.41-0.79; p <0.001). No corticosteroid benefit was seen in patients with MELD >51. The type of corticosteroids used (prednisone, prednisolone, or methylprednisolone) was not associated with survival benefit (p = 0.247). CONCLUSION Corticosteroids improve 30-day survival only among patients with severe AH, especially with MELD scores between 25 and 39. LAY SUMMARY Alcohol-associated hepatitis is a condition where the liver is severely inflamed as a result of excess alcohol use. It is associated with high mortality and it is not clear whether the most commonly used treatments (corticosteroids) are effective, particularly in patients with very severe liver disease. In this worldwide study, the use of corticosteroids was associated with increased 30-day, but not 90- or 180-day, survival. The maximal benefit was observed in patients with an MELD score (a marker of severity of liver disease; higher scores signify worse disease) between 25-39. However, this benefit was lost in patients with the most severe liver disease (MELD score higher than 51).

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a reversible leukoencephalopathy characterised by subcortical vasogenic oedema and neurological signs. We present the case of a 64-year-old woman who presented to hospital with symptomatic primary hyperparathyroidism. Her parathyroid hormone (PTH) level on admission was elevated at 1,330ng/l (normal range15-68ng/l) and her serum calcium measured 4.83mmol/l (normal range 2.25-2.54mmol/l). Technectium-99m sestamibi scan demonstrated a focus of radiotracer uptake consistent with a right upper parathyroid adenoma or carcinoma. After commencing appropriate medical treatment, the patient developed intractable seizures necessitating endotracheal intubation. Magnetic resonance imaging of her brain revealed bilateral symmetrical T2 hyperintensities in the posterior circulation consistent with PRES. Following stabilisation and further medical treatment for hypercalcaemia, the patient underwent a parathyroidectomy. Preoperative rapid PTH assay measured 1,021ng/l. Following excision, PTH levels fell to just 10ng/l. She was extubated in the intensive care unit on postoperative day 1 and made an uneventful recovery. At her 6-week follow-up appointment, all neurological symptoms had resolved. PRES is a rare neurological entity more often seen in the setting of hypertension, immunosuppression and renal failure. The development of new neurological manifestations in the setting of known risk factors should raise suspicion for the underlying diagnosis.

Abstract
Age-related diseases for which there are no effective treatments include cardiovascular diseases; neurodegenerative diseases such as Alzheimer's disease; eye disorders such as cataract and age-related macular degeneration; and, more recently, Severe Acute Respiratory Syndrome (SARS-CoV-2). These diseases are associated with plasma and/or tissue increases in cholesterol derivatives mainly formed by auto-oxidation: 7-ketocholesterol, also known as 7-oxo-cholesterol, and 7β-hydroxycholesterol. The formation of these oxysterols can be considered as a consequence of mitochondrial and peroxisomal dysfunction, leading to increased in oxidative stress, which is accentuated with age. 7-ketocholesterol and 7β-hydroxycholesterol cause a specific form of cytotoxic activity defined as oxiapoptophagy, including oxidative stress and induction of death by apoptosis associated with autophagic criteria. Oxiaptophagy is associated with organelle dysfunction and in particular with mitochondrial and peroxisomal alterations involved in the induction of cell death and in the rupture of redox balance. As the criteria characterizing 7-ketocholesterol- and 7β-hydroxycholesterol-induced cytotoxicity are often simultaneously observed in major age-related diseases (cardiovascular diseases, age-related macular degeneration, Alzheimer's disease) the involvement of these oxysterols in the pathophysiology of the latter seems increasingly likely. It is therefore important to better understand the signalling pathways associated with the toxicity of 7-ketocholesterol and 7β-hydroxycholesterol in order to identify pharmacological targets, nutrients and synthetic molecules attenuating or inhibiting the cytotoxic activities of these oxysterols. Numerous natural cytoprotective compounds have been identified: vitamins, fatty acids, polyphenols, terpenes, vegetal pigments, antioxidants, mixtures of compounds (oils, plant extracts) and bacterial enzymes. However, few synthetic molecules are able to prevent 7-ketocholesterol- and/or 7β-hydroxycholesterol-induced cytotoxicity: dimethyl fumarate, monomethyl fumarate, the tyrosine kinase inhibitor AG126, memantine, simvastatine, Trolox, dimethylsufoxide, mangafodipir and mitochondrial permeability transition pore (MPTP) inhibitors. The effectiveness of these compounds, several of which are already in use in humans, makes it possible to consider using them for the treatment of certain age-related diseases associated with increased plasma and/or tissue levels of 7-ketocholesterol and/or 7β-hydroxycholesterol.

Abstract
Abstract
Introduction
Minimally invasive adrenalectomy has become the standard of care internationally in benign adrenal disease. Intra-operative conversion to open surgery is associated with significantly increased morbidity and prolonged hospital stay. The aim of this systematic review is to identify risk factors associated with intra-operative conversion of minimally invasive adrenalectomy.
Method
This systematic review was conducted according to MOOSE guidelines. PubMed, EMBASE and Cochrane library were systematically searched for observational studies evaluating risk factors for intra-operative conversion of minimally invasive adrenalectomy to open surgery. Specific risk factors of interest included patient demographics, patient co-morbidities, tumour characteristics and histology.
Result
Eight studies met the inclusion criteria for analysis with a total of 2939 patients. 6.02% (n=177) required intra-operative conversion. 67.5% (n=1983) underwent laparoscopic transperitoneal adrenalectomy. There were no significant associations between any patient demographics or co-morbidities and intra-operative conversion. Tumour characteristics such as right sided tumours (pooled odds ratio (OR), 1.51; 95% Confidence Interval (CI), 0.98-2.32; p=0.06) and increasing tumour size (OR, 2.29; 95% CI, 1.4-3.74; p=0.001) were shown to be significantly associated with an increased risk of conversion. Pheochromocytoma (OR, 2.21; 95% CI, 1.89-2.58; p<0.0001) and malignancy (OR, 5.38; 95% CI, 2.1-13.81; p=0.005) were also significant predictors of intra-operative conversion.
Conclusion
Minimally invasive adrenalectomy has significantly reduced post-operative morbidity in patients requiring adrenal surgery but the need for intra-operative conversion remains significant. Identifying patients at increased risk of conversion pre-operatively may assist intra-operative decision making and contribute to improved patient outcomes.
Take-home message
Minimally invasive adrenalectomy carries a significant risk of conversion. Recognising patients with known risk factors for conversion aids risk stratification and may contribute to better outcomes.

Abstract
Abstract
Introduction
Despite the fact that esophageal food bolus obstruction is a common surgical problem, there are no clear guidelines on its management. Medical treatment with Buscopan and Glucagon is mostly in-effective, requiring a therapeutic Oesophago-Gastro-Duodenoscopy (OGD).
Method
All consecutive cases of food bolus obstructions (FBO) presenting to the Emergency Department (ED) for 18 month period between 01/01/2018 and 30/06/2019 were retrospectively reviewed.
Result
A total of 30 patients were admitted with food bolus obstruction via ED (1.67 per month). Females (67%) constituted most of these patients. Average age was 55 with range of 19-83. 84% of patients presented with Dysphagia, while Odynophagia (10%) and chest pain (6%) were other presenting symptoms. Average duration of symptoms was 17 hours (Range 2 – 48 hours). 44% of patients had OGD done under sedation while others (56%) had under General Anaesthesia (GA). In 70% of cases, food bolus was pushed into stomach, while it was retrieved out in 20%. In 10%, it had already spontaneously passed in stomach on OGD. The etiology of FBO was inflammatory in 60% cases, while an esophageal stricture was seen in 10% only. In 30% cases no cause of FBO was identified. Post-OGD length of stay was on average 1.15 days (range 12 hours – 7 days). 2 patients had aspiration pneumonia prolonging their hospital stay, there was no esophageal perforation or mortality.
Conclusion
Esophageal food bolus obstruction is a common surgical problem, OGD under GA is a safe recommended procedure, which often picks up an underlying pathology.

Abstract
Recent ethnobotanical studies have raised the hypothesis that religious affiliation can, in certain circumstances, influence the evolution of the use of wild food plants, given that it shapes kinship relations and vertical transmission of traditional/local environmental knowledge. The local population living in Jhelum District, Punjab, Pakistan comprises very diverse religious and linguistic groups. A field study about the uses of wild food plants was conducted in the district. This field survey included 120 semi-structured interviews in 27 villages, focusing on six religious groups (Sunni and Shia Muslims, Christians, Hindus, Sikhs, and Ahmadis). We documented a total of 77 wild food plants and one mushroom species which were used by the local population mainly as cooked vegetables and raw snacks. The cross-religious comparison among six groups showed a high homogeneity of use among two Muslim groups (Shias and Sunnis), while the other four religious groups showed less extensive, yet diverse uses, staying within the variety of taxa used by Islamic groups. No specific plant cultural markers (i.e., plants gathered only by one community) could be identified, although there were a limited number of group-specific uses of the shared plants. Moreover, the field study showed erosion of the knowledge among the non-Muslim groups, which were more engaged in urban occupations and possibly underwent stronger cultural adaption to a modern lifestyle. The recorded traditional knowledge could be used to guide future development programs aimed at fostering food security and the valorization of the local bio-cultural heritage.

Abstract
Background Transarterial chemoembolization (TACE) and bland embolization (TAE), performed for hepatocellular carcinoma (HCC), are often complicated by post-embolization syndrome (PES). There are limited data regarding the incidence of PES after TAE and the role of steroids in PES. We report the incidence of PES post TACE and TAE, identify predictors, and evaluate the role of steroids in PES. Methods Demographic and clinical variables of patients who underwent embolization were collected and PES was identified. Risk factors for PES, TACE and TAE were derived by logistic regression. We compared patients who received dexamethasone to those who did not, regarding baseline characteristics, occurrence of PES, and hospital stay. Results A total of 171 patients, average age 60.5 years, underwent the procedure, 77.8% were male, and 87.7% had cirrhosis. Of these 171, 107 underwent TACE and 64 TAE. Dexamethasone was given to 106 (61.9%) patients, of whom 85 had TACE and 21 TAE. One hundred twenty-four patients (72.5%) developed PES. PES occurred in more patients who underwent TACE, 80 (74.7%) vs. 44 (68.7%), and resulted in a longer hospital stay (1.47 vs. 1.12 days, P=0.034). Predictive factors for PES included female sex (odds ratio [OR] 2.76, 95% confidence interval [CI] 1.04-7.34; P=0.041), and alcohol-related HCC (OR 3.14, 95%CI 1.42-6.95; P=0.005). Dexamethasone did not affect the length of hospital stay (1.43 vs. 1.29 days, P=0.422) or the rate of prolonged hospitalization (18.8% vs. 15.4%, P=0.561). Conclusion There was no difference in the incidence of PES following TACE or TAE and the use of dexamethasone did not reduce the incidence of PES or the duration of hospital stay.

Abstract
Plant species of the Poaceae family are not only used as fodder and forage but also contribute substantially to the treatment of various health disorders, particularly in livestock. Consequently, the present study was aimed to document the therapeutic uses of Poaceae practiced by the inhabitants of the Punjab Province for the treatment of various veterinary health disorders. Semi structured interviews, group discussion and field walks were conducted to collect the data. Quantitative indices including cultural significance index (CSI), relative frequency of citations (RFC), fidelity level (FL), relative popularity level (RPL), and Jaccard Index (JI) were used for the data analysis. Traditional uses of 149 species belonging to 60 genera and 16 tribes of 5 sub families of Poaceae were recorded. Whole plants and leaves were the most consistently used parts with 40.94 and 29.53%. The plants were mainly given orally as fodder (59 reports) without processing followed by decoction (35 reports). Most of the species were employed to treat infectious diseases (25.93%), and digestive disorders (14.10%). Triticum aestivum had the highest CSI, RFC and RPL levels at 8.00, 0.96, 1.00, respectively, followed by Oryza sativa and Poa annua. Likewise, T. aestivum and Saccharum spontaneum had 100% FL and ROP. Jaccard index ranged from 12.25 to 0.37. Twelve plant species namely Chrysopogon zizanioides (anti-inflammatory), Pennisetum lanatum (improve bull fertility), Cymbopogon citratus (glandular secretion), Sorghum saccharatum and Themeda triandra (malaria), Aristida funiculate (anticancer), Koeleria argentia (skin allergies), Tetrapogon villosus (antibacterial), Cynodon radiatus (eyes infection), Sporobolus nervosa (Jaundice), Enneapogon persicus (antifungal), and Panicum repens (dysfunctional cattle organs) were reported for the first time, with novel ethnoveterinary uses. The inhabitants of the study area had a strong association with their surrounding plant diversity and possessed significant knowledge on therapeutic uses of Poaceae to treat various health disorders in animals. Plant species with maximum cultural and medicinal values could be a potential source of novel drugs to cure health disorders in animals and human as well.

Abstract
INTRODUCTION The diagnostic performance of ultrasound-fine needle aspiration to identify thyroid nodules harbouring malignancy remains variable. The aim of this study was to determine thyroid nodule size and cytological classification as predictors of malignancy risk. MATERIALS AND METHODS We conducted a retrospective cohort analysis at an academic hospital involving 499 consecutive patients who underwent thyroid surgery between 2004 and 2015. RESULTS A total of 503 thyroid nodules (499 patients, 84% female; mean age 50.8 years, standard deviation, SD, 15.4 years) were analysed. Of these, 19.5% were malignant. The mean (± SD) nodule size was 3.28 ± 1.63 cm and 3.27 ± 1.54 cm for benign and malignant nodules, respectively. The odds of malignancy for thyroid nodules less than 3.0 cm was similar to those for nodules of 3.0 cm or greater (0.26 compared with 0.29; p=0.77). Overall, the sensitivity and specificity of fine-needle aspiration in this cohort were 71.4% and 100%, respectively. The overall false negative rate was 5.4%. When the cut-off of 3.0 cm was used, the false negative rate in thyroid nodules less than 3.0 cm was 0% compared with 7.0% in nodules of 3.0 cm or greater. Thus, class (p<0.01) but not nodule size (p=0.49), was associated with higher malignancy risk. CONCLUSIONS Our results suggest that thyroid nodule size did not accurately predict the risk of thyroid malignancy irrespective of fine-needle aspiration cytology. Routine diagnostic thyroid lobectomy solely owing to thyroid nodule size of 3.0 cm or greater is currently not justified.

Abstract
Background: In 2012, the American Association for the Study of Liver Diseases published practice guidelines for the management of patients with ascites caused by cirrhosis, using data from randomized controlled trials (RCTs) and observational studies. We reexamined the strength of these RCTs by calculating the fragility index (FI), a novel metric proposed for evaluating the robustness of RCTs. Methods: We screened all RCTs referenced in the guidelines for specific criteria. We calculated the FI and fragility quotient (FQ), and analyzed the correlation between FI and several variables. Results: Twenty-one RCTs were included. The median (25th, 75th) FI and FQ were 1 (interquartile range [IQR] 0.5-6) and 0.070 (IQR 0.008-0.166), respectively. For studies that reported the number of patients lost to follow up (12 RCTs), the median of patients lost was 2 (IQR 0-6.5). There was no significant correlation between FI and sample size (rs=0.357), P-value (rs=-0.299), number lost to follow up (rs=0.355), Science Citation Index (rs=0.347), year of publication (rs=-0.085), blinding (rpb=-0.18) or number of centers (rpb=0.10). However, a significant correlation was seen between FI and number needed to treat (rs=-0.549; P=0.015). Conclusions: RCTs in the field of cirrhosis-related ascites are fragile. Of the 21 trials analyzed, 13 had an FI of 3 or below and these trials influenced 13 of the 49 recommendations in the guidelines. We recommend the incorporation of FI and FQ in addition to P-value to better understand the meaning of the results in gastroenterological studies.

Abstract
Abstract
Background and purpose
The present study was aimed to evaluate lipid-lowering and anti-atherogenic effect of an intravenous (IV) curcumin in the rabbit fed high cholesterol diet (HCD).
Methods
New Zealand white male rabbits (4–6 months old, n=25, weight 2.286±0.256 kg)were fed on a normal chow enriched with 0.5% (w/w) cholesterol for 5 weeks. Atherosclerotic rabbits were randomly divided into three group, including a control group receiving intravenous (IV) injection of saline buffer, two treatment groups receiving IV injection of curcumin at two different dosages, 1and 10 mg/kg/week, for 4 weeks. Blood samples were collected from fasted rabbits at pre- (week 5) and post-treatment (week 11) points for analysis of serum lipid levels, including low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), triglyceride (TG), and total cholesterol (TC). Aortic arch atherosclerotic lesions were assessed using hematoxylin and eosin (H&E) staining.
Results
To evaluate curcumin's effects on the hyperlipidemic states and atherosclerosis plaque, HCD-fed rabbits were weekly treated with the injectable curcumin at the low (1mg/kg/week) and high (10 mg/kg/week) doses by 4 weeks. At week 4 in compared with the control group, low-dose curcumin could reduce serum levels of LDL-c, HDL-c, TG, and TC by −6.22% ±1.77, −35.24% ±12.49, −29.84% ±10.14, −14.19% ±5.19, respectively. In the case of high-dose curcumin, serum levels of LDL-c, HDL-c, TG, and TC were changed by −44.36%±3.24, 14.05% ±6.39, −25.92% ±5.57, −56.59% ±10.22, respectively, when compared with the control group at week 4. Low-dose curcumin after 4 weeks' treatment could reduce serum levels LDL-c, HDL-c, TG, and TC up to 103±28 mg/dL, 18.33±4.66 mg/dL, 97.5±31 mg/dL, and 356.5±19.5 mg/dL, respectively, when compared with the base line levels (week 0). High-dose curcumin after 4 weeks' treatment could decrease serum levels of LDL-c, HDL-c, TG, HDL-c, and TC up to 207±17.04 mg/dL, 15.5±0.5 mg/dL, 333±40 mg/dL, and 514.5±22.23 mg/dL, respectively (Figure). H&E staining declared that atherosclerotic lesion grades were significantly lower in the curcumin-treated groups than the control group.
Changes of lipids in rabbits on curcumin
Conclusions
The injectable curcumin at the low (1mg/kg) and high (10 mg/kg) could significantly improve dyslipidemia and alleviate atherosclerotic lesion in HCD-induced atherosclerotic rabbits.

Abstract
Background Ursodeoxycholic acid (UDCA) and obeticholic acid are currently approved treatments for primary biliary cholangitis (PBC). Since some patients do not respond adequately to UDCA, other therapies, such as bezafibrate, have been developed. In this meta-analysis we evaluated the efficacy and safety of using both UDCA and bezafibrate in patients with an inadequate response to UDCA. Methods We evaluated all randomized controlled trials comparing the combination of UDCA and bezafibrate with UDCA monotherapy. Standardized mean difference (SMD) was used to assess the treatment effect of combination therapy compared with UDCA alone. Results Ten trials with a total of 369 patients were analyzed. UDCA and bezafibrate combination therapy was more effective than UDCA monotherapy in improving alanine aminotransferase (SMD -2.04, 95% confidence interval [CI] -3.30 to -0.79), alkaline phosphatase at both less than 12 months (SMD -3.63, 95%CI -6.43 to -0.84) and more than 12 months (SMD -2.33, 95%CI -4.03 to -0.63), gamma-glutamyltransferase (SMD -1.29, 95%CI -2.67 to 0.08), triglyceride (SMD -0.80, 95%CI -1.41 to -0.19), immunoglobulin M (SMD -1.48, 95%CI -2.39 to -0.56), and cholesterol (SMD -4.61, 95%CI -7.34 to -1.89). There was no difference between the 2 groups in bilirubin, aspartate aminotransferase or albumin. None of the adverse effects differed statistically between the 2 groups. Conclusion UDCA and bezafibrate combined treatment is superior to UDCA alone in UDCA non-responders with regard to decreasing liver biochemistry markers, without any significant increase in side effects in patients with PBC.

Abstract
Background The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system is increasingly being used for genome editing experiments. It is a system to add, delete and/or replace parts of a gene in situ in a time- and cost-efficient manner. The genome of many organisms has been edited using this system. We tested the CRISPR/Cas9 system in Aphanomyces invadans, an oomycete, which is the causative agent of epizootic ulcerative syndrome (EUS) in many fish species. Extracellular proteases produced by this oomycete are believed to play a role in EUS virulence. Methods We designed three single guide-RNAs (gRNA) to target A. invadans serine protease gene. These gRNAs were individually combined with the Cas9 to form ribo-nucleo-protein (RNP) complex. A. invadans protoplasts were then transfected with RNP complexes. After the transfection, the target gene was amplified and subjected to sequencing. Zoospores of A. invadans were also transfected with the RNP complex. Three groups of dwarf gourami (Trichogaster lalius) were then experimentally inoculated with (i) non-treated A. invadans zoospores; (ii) RNP-treated A. invadans zoospores; and (iii) autoclaved pond water as negative control, to investigate the effect of edited serine protease gene on the virulence of A. invadans in vivo. Results Fluorescence microscopy showed sub-cellular localization of RNP complex in A. invadans protoplasts and zoospores. Sequencing results from the protoplast DNA revealed a point mutation in the target gene. A matching mutation was also detected in zoospores after similar treatment with the same RNP complex. In vivo results showed that the CRISPR/Cas9-treated A. invadans zoospores did not produce EUS clinical signs in the fish. These results were then confirmed by histopathological staining of the muscle sections using Gomori’s methenamine silver nitrate and hematoxylin and eosin stains. Conclusions Results obtained in this study indicate that the RNP complex caused effective mutation in the target gene. This hindered the production of serine protease, which ultimately impeded the manifestation of EUS in the fish. Our methods thus establish a promising approach for functional genomics studies in A. invadans and provide novel avenues to develop effective strategies to control this pathogen.

Abstract
Background/Aim: Curcumin is being widely investigated for its anticancer properties and studies in the literature suggest that curcumin distributes to a higher degree in tumor versus non-tumor cells. In the current study, we report on investigation of the distribution of curcumin and metabolism to THC in PBMC from healthy individuals and chronic lymphocytic leukemia (CLL) patients following exposure to Lipocurc™ (liposomal curcumin). Materials and Methods: The time and temperature-dependent distribution of liposomal curcumin and metabolism to tetrahydrocurcumin (THC) were measured in vitro in human peripheral blood mononuclear cells (PBMC) obtained from healthy individuals, PBMCHI(cryopreserved and freshly isolated PBMC) and CLL patients (cryopreserved PBMC) with lymphocyte counts ranging from 17-58×106 cells/ml (PBMCCLL,Grp 1) and >150×106 cells/ml (PBMCCLL,Grp 2). PBMC were incubated in plasma protein supplemented media with Lipocurc™ for 2-16 min at 37°C and 4°C and the cell and medium levels of curcumin determined by LC-MS/MS. Results: PBMC from CLL patients displayed a 2.2-2.6-fold higher distribution of curcumin compared to PBMCHICurcumin distribution into PBMCCLL, Grp 1/Grp 2 ranged from 384.75 - 574.50 ng/g w.w. of cell pellet and was greater compared to PBMCHIthat ranged from 122.27-220.59 ng/g w.w. of cell pellet following incubation for up to 15-16 min at 37°C. The distribution of curcumin into PBMCCLL,Grp 2 was time-dependent in comparison to PBMCHIwhich did not display a time-dependence and there was no temperature-dependence for curcumin distribution in either cell type. Curcumin was metabolized to THC in PBMC. The metabolism of curcumin to THC was not markedly different between PBMCHI(range=23.94-42.04 ng/g w.w. cell pellet) and PBMCCLL,Grp 1/Grp 2 (range=23.08-48.22 ng/g. w.w. cell pellet). However, a significantly greater time and temperature-dependence was noted for THC in PBMCCLL,Grp 2 compared to PBMCHIConclusion: Curcumin distribution into PBMC from CLL patients was higher compared to PBMC from healthy individuals, while metabolism to THC was similar. The potential for a greater distribution of curcumin into PBMC from CLL patients may be of therapeutic benefit.

Abstract
BACKGROUND Proteases produced by many microorganisms, including oomycetes, are crucial for their growth and development. They may also play a critical role in disease manifestation. Epizootic ulcerative syndrome is one of the most destructive fish diseases known. It is caused by the oomycete Aphanomyces invadans and leads to mass mortalities of cultured and wild fish in many countries. The areas of concern are Australia, China, Japan, South and Southeast Asian countries and the USA. Extracellular proteases produced by this oomycete are believed to trigger EUS pathogenesis in fish. To address this activity, we collected the extracellular products (ECP) of A. invadans and identified the secreted proteins using SDS-PAGE and mass spectrometery. A. invadans was cultivated in liquid Glucose-Peptone-Yeats media. The culture media was ultra-filtered through 10 kDa filters and analysed using SDS-PAGE. Three prominent protein bands from the SDS gel were excised and identified by mass spectrometery. Furthermore, we assessed their proteolytic effect on casein and immunoglobulin M (IgM) of rainbow trout (Oncorhynchus mykiss) and giant gourami (Osphronemus goramy). Antiprotease activity of the fish serum was also investigated. RESULTS BLASTp analysis revealed that the prominent secreted proteins were proteases, mainly of the serine and cysteine types. Proteins containing fascin-like domain and bromodomain were also identified. We could demonstrate that the secreted proteases showed proteolytic activity against the casein and the IgM of both fish species. The anti-protease activity experiment showed that the percent inhibition of the common carp serum was 94.2% while that of rainbow trout and giant gourami serum was 7.7 and 12.9%, respectively. CONCLUSIONS The identified proteases, especially serine proteases, could be the potential virulence factors in A. invadans and, hence, are candidates for further functional and host-pathogen interaction studies. The role of identified structural proteins in A. invadans also needs to be investigated further.

Abstract
BACKGROUND/AIM The aim of this study was to investigate the distribution of curcumin (in the form of Lipocurc™) and its major metabolite tetrahydrocurcumin (THC) in Beagle dog and human red blood cells, peripheral blood mononuclear cells (PBMC) and hepatocytes. MATERIALS AND METHODS Lipocurc™ was used as the source of curcumin for the cell distribution assays. In vitro findings with red blood cells were also compared to in vivo pharmacokinetic data available from preclinical studies in dogs and phase I clinical studies in humans. RESULTS High levels of curcumin were measured in PBMCs (625.5 ng/g w.w. cell pellet or 7,297 pg/106 cells in dog and 353.7 ng/g w.w. cell pellet or 6,809 pg/106 cells in human) and in hepatocytes (414.5 ng/g w.w. cell pellet or 14,005 pg/106 cells in dog and 813.5 ng/g w.w. cell pellet or 13,780 pg/106 cells in human). Lower curcumin levels were measured in red blood cells (dog: 78.4 ng/g w.w. cell pellet or 7.2 pg/106 cells, human: 201.5 ng/g w.w. cell pellet or 18.6 pg/106 cells). A decrease in the medium concentration of curcumin was observed in red blood cells and hepatocytes, but not in PBMCs. Red blood cell levels of THC were ~5-fold higher in dog compared to human and similar between dog and human for hepatocytes and PBMCs. The ratio of THC to curcumin found in the red blood cell medium following incubation was 6.3 for dog compared to 0.006 for human, while for PBMCs and hepatocytes the ratio of THC to curcumin in the medium did not display such marked species differences. CONCLUSION There was an excellent correlation between the in vitro disposition of curcumin and THC following incubation with red blood cells and in vivo plasma levels of curcumin and THC in dog and human following intravenous infusion. The disposition of curcumin in blood cells is, therefore, species-dependent and of pharmacokinetic relevance.

Abstract
Angiomyofibroblastoma is a rare, well circumscribed benign mesenchymal neoplasm, usually arising in the pelviperineal region, especially the vulva and apparently composed of stromal cells distinctive to this anatomic region. Preoperative diagnosis of Angiomyofibroblastoma is very difficult, mostly diagnosed as Barthloin cyst due to its anatomical location. It is a histological diagnosis. In this article we report a case of Angiomyofibroblastoma of vulva.

Abstract
Crizotinib (Xalkori®) and nilotinib (Tasigna®) are tyrosine kinase inhibitors approved for the treatment of non-small cell lung cancer and chronic myeloid leukemia, respectively. Both have been shown to result in electrocardiogram rate-corrected Q-wave T-wave interval (QTc) prolongation in humans and animals. Liposomes have been shown to ameliorate drug-induced effects on the cardiac-delayed rectifier K(+) current (IKr, KV11.1), coded by the human ether-a-go-go-related gene (hERG). This study was undertaken to determine if liposomes would also decrease the effect of crizotinib and nilotinib on the IKr channel. Crizotinib and nilotinib were tested in an in vitro IKr assay using human embryonic kidney (HEK) 293 cells stably transfected with the hERG. Dose-responses were determined and the 50% inhibitory concentrations (IC50s) were calculated. When the HEK 293 cells were treated with crizotinib or nilotinib that were mixed with liposomes, there was a significant decrease in the IKr channel inhibitory effects of these two drugs. When isolated, rabbit hearts were exposed to crizotinib or nilotinib, there were significant increases in QTc prolongation. Mixing either of the drugs with liposomes ameliorated the effects of the drugs. Rabbits dosed intravenously (IV) with crizotinib or nilotinib showed QTc prolongation. When liposomes were injected prior to crizotinib or nilotinib, the liposomes decreased the effects on the QTc interval. The use of liposomal encapsulated QT-prolongation agents, or giving liposomes in combination with drugs, may decrease their cardiac liability.

Abstract
Data on road traffic accident (RTA) injuries and their outcome are scarce in Pakistan. This study assessed patterns of RTA injuries reported in Rawalpindi city using standard surveillance methods. All RTA injury patients presenting to emergency departments of 3 tertiary care facilities from July 2007 to June 2008 were included. RTA injuries (n = 19 828) accounted for 31.7% of all injuries. Among children aged 0-14 years females suffered twice as many RTA injuries as males (21.3% versus 11.4%), whereas this trend reversed for the age group 15-24 years (41.9% versus 21.7%). One-fifth of injuries were either fractures or concussion. Severity and outcome of injuries were worse for the age group 45 years and older. For every road traffic death in Rawalpindi city, 29 more people were hospitalized and 177 more received emergency department care. These results suggest the need for better RTA injury surveillance to identify preventive and control measures for the increasingly high road disease burden in this city.

Abstract
Sebaceous differentiation in salivary gland tissue is common. However, sebaceous neoplasms within the salivary glands are rare. We present the case of a sebaceous lymphadenoma with unusual features, arising in the parotid gland of a 60-year-old male. To the best of our knowledge, this is the first report of the ultrasound and MRI characteristics of this rare tumour. The difficulties encountered in reaching a definitive diagnosis both radiologically and histologically are described.

Abstract
OBJECTIVES To measure hyaluronic acid (HA) levels, which are raised in active rheumatoid arthritis (RA), in patients with early RA, and to assess the correlation with clinical and laboratory indices of disease activity and with subsequent radiographic erosive status. PATIENTS AND METHODS Patients fulfilling ACR criteria were recruited into a prospective cohort within 6 months of disease onset and reviewed every 6 months. An HA binding protein based sandwich ELISA was used to measure HA in 240 sera from 82 patients at regular intervals. RESULTS Patients had higher HA levels than age matched healthy blood donor controls (median 37.4 v 29.1 ng/ml, respectively, p<0.02), which increased with more prolonged disease. Baseline HA level correlated with measures of disease activity, including swollen and tender joint counts, HAQ, global assessments, ESR, and CRP; was higher in men; and increased with age. There was no relationship with HLA-DRB1 shared epitope or rheumatoid factor status. At 6 and 12 month follow up visits, HA levels were higher in patients who later developed erosions. However, a raised HA level was not a good predictor of erosions. CONCLUSIONS Serum HA level correlates with clinical and laboratory measures of disease activity in early RA, but is unlikely to be of practical use in clinical practice.

Abstract
Phagocytosis is increased by Fcgamma receptors (FcgammaRs), and studies with syk(-/-) macrophages demonstrated that Syk kinase is required for FcgammaR phagocytosis. Similar studies with macrophages lacking the Src family kinases Hck, Fgr, and Lyn showed that these kinases are not required for phagocytosis but that they enhance the rate of particle engulfment. In this report we show that both wild-type and hck(-/-)fgr(-/-) macrophages expressed Fyn, Src, and Yes and that these kinases were activated on ingestion of immunoglobulin G (IgG)-coated particles and redistributed, together with Syk, to actin-rich phagocytic cups and the phagosomal membrane. At doses blocking IgG-dependent phagocytosis, the tyrosine kinase inhibitors PP1 and piceatannol inhibited both Src family kinase and Syk activities, as well as their redistribution to actin-rich phagocytic cups. Hck, Fgr, and Lyn were dispensable for lysosome-phagosome fusion (PLF) induced by IgG-coated particles. However, PP1 or piceatannol hampered unopsonized yeast-induced PLF despite the fact that they did not block yeast internalization.

Abstract
Chemokines trigger rapid integrin-dependent lymphocyte arrest to vascular endothelium. We show that the chemokines SLC, ELC, and SDF-1alpha rapidly induce lateral mobility and transient increase of affinity of the beta2 integrin LFA-1. Inhibition of phosphatidylinositol 3-OH kinase (PI(3)K) activity blocks mobility but not affinity changes and prevents lymphocyte adhesion to ICAM-1 immobilized at low but not high densities, suggesting that mobility enhances the frequency of encounters between high-affinity integrin and ligand but that at higher ligand density affinity changes are sufficient for arrest. Thus, chemokines trigger, through distinct signaling pathways, both a high-affinity state and lateral mobility of LFA-1 that can coordinately determine the vascular arrest of circulating lymphocytes under physiologic conditions.

Abstract
We describe 10 patients (6 females and 4 males) from 6 unrelated families with an autosomal recessive disease characterized by simultaneous presentation of nodulosis, arthropathy and osteolysis. They were followed up regularly at King Faisal Specialist Hospital and Research Center in Saudi Arabia for clinical evaluation, serial blood work-up, and evaluating radiological changes. Nodulosis and arthropathy were the clinical criteria for inclusion in this study, and the ten patients fulfilled these criteria. All patients had nodulosis and distal arthropathy. Eight patients (80%) presented with deformed hands and four (40%) with painful hands. All patients had parents who were first cousins and three families had more than one affected child, the finding suggesting autosomal recessive inheritance. Osteopenia and undertubulation of bones distally more than proximally, and upper limbs affected more often than lower limbs, were found in all patients. Osteolysis was seen in carpal and tarsal bones. Other common findings were sclerotic cranial sutures, brachycephaly, and broad medial clavicles. This novel phenotype should be considered in the differential diagnosis of chronic arthritis. Familial arthropathies are more often seen in communities where interfamilial marriage is common. Such a collection of patients is ideal for homozygosity mapping of the disease locus.

Abstract
We have investigated the role of cAMP and cAMP-dependent protein kinase (cAPK) in neutrophil phagocytosis. Inhibition of cAPK with H-89 reduced complement- and IgG-dependent phagocytosis to 83 and 46%, respectively. Fluorescence intensity measurements of phalloidin-stained actin in neutrophils showed a reduced amount of filamentous actin (F-actin) in pseudopods and around the phagosome in cells treated with H-89 or cAMP-elevating agents (forskolin and rolipram). The amount of phosphotyrosine-containing proteins was also reduced in pseudopods and around the phagosome. Taken together, the data show that cAMP/cAPK regulates F-actin reorganization during receptor-mediated phagocytosis, particularly triggered by IgG-FcR interaction. Our results support the hypothesis that active subcortical reorganization of F-actin is a prerequisite for FcR-mediated phagocytosis, but is less important during CR3-mediated ingestion.
