Abstract
Thyroid carcinoma is uncommon. Papillary thyroid carcinoma (PTC) represents the majority of differentiated thyroid carcinoma and is a recognised complication of prior exposure to ionizing radiation. Even more uncommon is the synchronous occurrence of PTC with Hodgkin lymphoma (HL) as multiple primary malignancies. We report a 33-year-old mother of three who developed asymptomatic thyroid nodule for four years, and neck swelling for the recent ten months. She denied constitutional symptoms or B symptoms, and thyroid profiles were normal. Initially, metastatic thyroid cancer was suspected based on ultrasound scan findings of enlarged left thyroid gland and enlarged supraclavicular lymph nodes (LN). However, fine needle aspiration examinations of the thyroid nodule were inconclusive, and the supraclavicular LN was suspicious of HL. Computerised tomography scan detected a large mass at the thyroid glands and lymphadenopathies in the mediastinal, hilar, subcarinal and axilla with dimensions up to 6 cm. Left hemi-thyroidectomy with left supraclavicular LN biopsy revealed PTC in the left thyroid lobe measuring 38 x 25 x 18 mm, and the left supraclavicular LN was not definitive of HL. Completion thyroidectomy on the right side, bilateral central neck dissection and excision biopsy of the right supraclavicular LN revealed the presence of HL in the right supraclavicular LN, and both HL and metastatic PTC in right central LN. After multidisciplinary discussions, the patient received chemotherapy at four weeks postoperatively and achieved complete remission. This report highlights the importance of patient-centered approach and multidisciplinary consensus within lack of established guidelines, given rarity of the case.

Abstract
Purple Sweet Potato (PSP) in Malaysia is an abandoned crop. Even though it has various health benefits and nutritional values, consumers, especially Malaysians, still lack purple sweet potato consumption. It has a high dietary fibre content, a low glycemic index, and contains proteins, minerals, polyphenols, and anthocyanin. The National Health Morbidity Survey (Malaysia) in 2019 reported that 94% of Malaysian adults lack fiber consumption in their dietary patterns. As a result, it may become an alternative crop for individuals who consume less nutrients and fibre as a result of dietary choices and health issues. This one-of-a-kind crop also contains anti-oxidative, hepatoprotective, anti-inflammatory, anti-tumor, anti-diabetic, anti-microbial, anti-obesity, and anti-aging qualities. Due to the lack of a commercial food product based on this crop, it has become an unpopular crop among Malaysians. Purple sweet potato makes only a few Malaysian sweets and traditional snacks. Nonetheless, Malaysian customers continue to ignore it. Thus, Purple Sweet Potato Cracker was made, and a proximate analysis was conducted to examine its physicochemical content. It was found that the newly developed PSP crackers were high in fiber, vitamins, and minerals, as well as in calcium (1332.08 mg/kg) and contained anthocyanins of 6.68 mg/L. Besides that, this special cracker is free from food preservatives without coloring agents and additives. The processing of Purple Sweet Potato Cracker carries important features for small-medium entrepreneurs, which will contribute to the Malaysian economy perspectives, as it has a good potential to be marketed in domestic and international commercial food outlets.

Abstract
This paper aims to identify the challenges of the cook-chill system implementation in school foodservice. In this qualitative approach, data were gathered through interviews with food contractors in seven different school in Selangor. Three issues, including a lack of awareness about the cook-chill system, inadequate management, and lack of training, were discovered using qualitative content analysis (QCA). The respondents believed the system was better suited for airlines or hospitals than school foodservice operations, which produced a large volume of meals everyday. This study could contribute a better understanding on the complexity of the cook-chill system, particularly for the school foodservice.
Keywords: School foodservice; cook-chill system; challenges; implementation

Abstract
Abstract Pakistan is an agricultural country and fisheries play a very important role in the economic development of the country. Different diseases are prevalent in Pakistani fish but information related to the causative agents is not well-known. Keeping in view the significance of bacterial pathogens as the causative agents of multiple fish diseases, the present study was conducted for identification, characterization and analysis of virulence genes of Aeromonas spp. isolated from diseased fishes. A total of fifty fish samples having multiple clinical indications were collected from different fish farms of district Kasur, Punjab Pakistan. For isolation of Aeromonas spp. samples were enriched and inoculated on Aeromonas isolation medium. Isolates were identified and characterized by different biochemical tests, Analytical Profile Index (API) 20E kit and Polymerase Chain Reaction (PCR) assays. All isolates were screened for three putative virulence genes including aerolysin (aer), haemolysin (hyl) and heat labile cytotonic enterotoxin (alt). Seven isolates of Aeromonas (A.) hydrophila were retrieved and identified based on API 20E. These isolates were further confirmed as A. hydrophila on the basis of PCR assays. Three isolates were detected positive for the presence of virulence genes (alt and hyl). Whereas aerolysin (aer) gene was not present in any of A. hydrophila isolates. The present study confirmed A. hydrophila as the causative agent of epizootic ulcerative syndrome and motile Aeromonas septicemia in fish farms of district Kasur, Punjab Pakistan. Moreover, detection of two virulence genes (alt and hyl) in A. hydrophila isolates is a threat for fish consumers of study area.

Abstract
Introduction: The study aimed to target the current practices of the orthopaedic community in outpatient (OPD), emergency (ER) and surgical services (OT) during COVID-19. Material and method: This study surveyed 303 orthopaedic surgeons from all over Pakistan. The survey had 30 questions targeting the setup of outpatient, emergency and operation services in orthopaedic departments of different hospitals in Pakistan. Result: A total of 302 surgeons were included from 53 cities all over Pakistan. Between 35-48% of the respondents reported lack of availability of standard operating procedures in OPD, ER and in OT. Majority of the respondents noted that their OPD and surgical practice had been affected to some degree and 69% of the surgeons were only doing trauma surgery. This trend was higher in younger consultants of less than 45 years of age (p<0.001). Almost two-third of the surgeons, mostly senior (p=0.03) were using surgical masks as the only protective measure during various practices of OPD, ER and OT, while most of the setups were not assessing patients even for signs and symptoms of COVID. Almost 89% of the orthopaedic community is facing definite to mild stress during this pandemic and this has significantly affected the senior surgeons (p=0.01). Conclusion: Our study highlighted that COVID-19 has resulted in marked changes to the practices of the majority of Pakistani orthopaedic surgeons. Despite a sharp upsurge in the number of cases and mortality due to COVID-19, guidelines were still lacking at most of the settings and a substantial percentage of the orthopaedic community were not following adequate safety measures while attending to patients.

Abstract
In the current study, we applied laser induced breakdown spectroscopy (LIBS) to determine the elemental distribution of nutritional and trace heavy metals in pepper powders available in Pakistan using the standard calibration curve of laser induced breakdown spectroscopic (CC-LIBS) technique. The samples were found to contain elements such as K, Ca, Mg, Na, Fe, Zn, Al, Pb, Cu, and Cr. In addition, we also identified the atmospheric H-alpha line of hydrogen in the spectra, which was used to estimate the electron number density. To achieve a highly sensitive LIBS system to determine the trace amounts of nutritional and toxic metals in the pepper powders and to achieve the best limit of detection, the LIBS system was optimized by studying the dependency of the LIBS signal intensity on laser irradiance, variation in spacing between the focusing lens and target, as well as on the gate width. To justify the results of the LIBS study, we also determined the concentration of similar (duplicate) peppers by digesting the samples in appropriate solvents using a standard method such as inductively coupled plasma-optical emission spectrometry (ICP-OES). The minimum detection limit was obtained for trace heavy metals from the calibration curves. The results of LIBS displayed noteworthy conformity with those acquired from the ICP-OES analysis. The results of both the techniques clearly revealed that K was the most abundant element in all the peppers, followed by Ca, Mg, Na, Fe, Al, Pb, Zn, Cu, and Cr. The relative accuracy of our LIBS system for different species as compared with the ICP technique was in the range of 0.08-0.3 at 2.5% error confidence. Conclusively, the present work demonstrated the suitability of the LIBS technique due to its rapid, non-destructive, and eco-friendly approach for food security.

Abstract
INTRODUCTION Occult primary breast carcinoma (OBC) manifesting as axillary nodal metastasis without an identifiable breast primary is exceptionally rare. It continues to pose a diagnostic challenge to pathologists. Here, we report a case of OBC with emphasis on the usefulness of immunohistochemistry to determine the primary site of tumour. CASE REPORT A 58-year-old female presented with a 3-cm painless right axillary mass. Extensive radiological investigations that include mammography, ultrasonography of the breasts and positron emission tomography (PET) scan failed to conclude the primary site of the tumour. Histological examination of the lymph node revealed loosely cohesive sheets of poorly differentiated malignant cells, without discernible glandular or squamous differentiation. Immunohistochemically, the malignant cells exhibited diffuse immunoreactivity toward pan-cytokeratin and CK7, while leukocyte common antigen, S100 and CK20 were negative. A second panel of immunomarkers was carried out. The malignant cells expressed breast-specific markers (GATA-3, GCDFP-15 and mammaglobin), and were negative for ER, PR and TTF-1 immunohistochemistry. A diagnosis of OBC was rendered. DISCUSSION Breast primary must always be considered in the differential diagnosis in patients with sole presentation of axillary lymphadenopathy. The breast-specific immunomarkers play a pivotal role in the diagnosis of ER, PR-negative occult breast cancer.

Abstract
Fuller's earth, most commonly known as Multani Matti (clay) in Urdu, among its various utilizations is traditionally used in skin care cosmetics, particularly for removing blackheads and to treat oily skin. It is also used for improving skin complexion. In this paper, laser-induced breakdown spectroscopy (LIBS) was effectively employed for the quantitative investigation of various clay samples for their special uses. To get the LIBS spectra with an optimal signal-to-noise as well as for a more robust and accurate analytical investigation, different experimental parameters (laser energy, gate delay time, and the distance between target and focusing lens) were optimized before the experiments on actual samples. The analysis of emission spectra revealed the presence of many different elements, including Al, Ca, Fe, Mg, Mn, Na, K, Li, S, Si, and Zn. The electron number density and plasma temperatures were determined using the Stark broadened line profile and Boltzmann plot method, respectively. To determine the relative concentration of observed elements, we used an integrated intensity ratio method, integrated intensity of every line from all elements, and calibration free (CF)-LIBS. The prevailing condition of local thermodynamic equilibrium during the experimental executions was verified with multiple criteria. The spectral lines used in CF-LIBS were characterized for the influence from the self-absorption phenomenon, but the same was found insignificant. The findings of our LIBS system were found to agree excellently with the outcomes of the inductively coupled plasma/optical emission spectroscopy, thereby yielding a high statistical correlation factor and hence enlighten the significance of LIBS as a safe and reliable tool for elemental analysis of clay samples.

Abstract
Haemorrhage arising from gastric arteriovenous malformation (AVM) is rare and normally occurs in the elderly. Bleeding gastric AVM presenting in the younger age group is even rarer. We report a case of a 14 year old boy who presented with recurrent episodes of haematemesis. He subsequently underwent a proximal gastrectomy and the histological examination confirmed a gastric AVM. After reviewing the literature we believe this is the youngest ever reported case of bleeding gastric AVM reported in English literature.

Abstract
BACKGROUND : Pain on injection is still a major problem with propofol. We performed this study to compare different doses of intravenous (i.v.) ketorolac with and without venous occlusion and its effect on the incidence and the severity of the pain after propofol injection. METHODS We conducted a prospective, randomized and double-blind study of 180 patients (20-60 years of age.) scheduled to undergo elective surgery. Six groups of patients were generated: group A received normal saline (NS) 2 ml i.v.; groups B, C, D received ketorolac 10 mg in 2 ml NS with venous occlusion (VO) and a subsequent propofol injection at either 30, 60 or 120 s; groups E and F received ketorolac 15 mg and 30 mg in 2 ml NS and propofol was injected after 60 s. The pain perception was assessed during injection of propofol in all patients. RESULT : The incidence of propofol-associated injection pain was for A: 46.7%; B: 43.4%; C: 23.3%; D:16.7%; E: 20%, and F: 10%. The incidence of pain following propofol injection was reduced by i.v. ketorolac 10 mg with venous occlusion for 120 s. Furthermore, i.v. ketorolac 15 mg and 30 mg but not 10 mg following propofol injection after 60 s without venous occlusion revealed significant pain reduction when compared to saline group. There was no difference in venous sequelae at 7 days postoperatively between the groups. CONCLUSION Our results suggested that pretreatment with i.v. 15 and 30 mg ketorolac reduces pain following propofol injection. Moreover, pretreatment with i.v. ketorolac 10 mg with venous occlusion for 120 s achieves the same pain relief effect.

Abstract
Endogenous opioid peptides play an essential role in the intrinsic modulation and control of inflammatory pain, and could be therapeutically useful. These opioid peptides are synthesized as parts of larger precursor molecules. One such precursor molecule is pro-opiomelanocortin (POMC). In this study, we developed a gene-gun method for the transfer of POMC cDNA in vivo, and investigated its therapeutic effect on inflammatory pain in a rat model of formalin-induced pain. Human POMC cDNA was cloned into a modified pCMV plasmid and delivered to the skin of rats by gene gun. Three days after gene-gun injection, 1% formalin was injected. Endorphin levels were measured in the serum and skin after the formalin test, and skin histology was used to detect endorphin after green fluorescent protein (GFP; control) or POMC cDNA transfer. There was no significant difference in the results of acute nociceptive tests between the experimental and control groups. There was also no difference in response between the groups to phase 1 of the formalin test. However, rats which received POMC cDNA via gene-gun injection showed a significantly reduced response in phase 2 of the formalin test. Endorphin immunoreactivity in the skin increased approximately three- to four-fold in experimental animals compared with GFP-treated controls at day 3 after injection. The phase 2 response in animals treated with formalin and naloxone did not differ significantly from the control, implying that the analgesic effects of POMC cDNA particle injection in phase 2 of the formalin test are reversed by naloxone. There are two major findings from this study. First, in vivo DNA delivery by gene gun to the skin is feasible. Second, the production of beta-endorphin is insufficient to block phasic pain, but is effective against sensitization of the afferent neurons during phase 2 of the formalin test.

Abstract
Activation of cutaneous C-fibers by capsaicin or sciatic nerve transection increases the number of astrocytic gap junctions as well as the levels of connexin 43 in the dorsal horn on the stimulated side. Changes in connexin 37 mRNA expression following nerve injury have not been previously documented. We examined the role of gap junction protein connexin 37 in neuropathic hypersensitivity following peripheral nerve injury. Study results showed ipsilaterally increased connexin 37 mRNA levels proximally and distally in rat sciatic nerves after injury and behavioral thermal hyperalgesia at 7 and 14 days. Proximal and distal connexin 37 mRNA levels returned to baseline by 21 days. Sciatic nerve connexin 37 mRNA increases were proportional to the extent of thermal hyperalgesia, but skin, muscle, and lumbar spinal cord connexin 37 mRNA showed no significant changes. Neuropathic pain relief correlated with downregulation of connexin 37 mRNA. Results indicate that upregulation of connexin 37 mRNA following sciatic nerve injury correlates with subsequent thermal hyperalgesia, which suggests that gap junctions (connexin 37) are responsible for the hyperexcitability following peripheral nerve injury.
