Abstract
Injury to the peripheral sensory nerves of the hand and wrist is common and can lead to debilitating neuromas and significantly impair patients' quality of life. Target-muscle reinnervation (TMR) is a novel method for treating neuromas that can result in significant clinical improvement. However, TMR for the peripheral sensory nerves in the hand and wrist is restricted by the limited options for motor branches. The adaptability of the anterior interosseous nerve (AIN) as a target for TMR treating peripheral sensory neuroma has not been thoroughly investigated or implemented therapeutically. This study aimed to evaluate the use of AIN as a viable recipient of TMR for treating peripheral sensory neuromas around the wrist. In this retrospective study, eight patients were included over 18 months from June 2021 to January 2023 at Hamad Medical Corporation. The average follow-up time after TMR was 13 months. The peripheral sensory nerves involved were the radial sensory nerve in five cases, the palmar cutaneous branch of the median nerve in one case, and the median nerve in one case. The preoperative average VAS pain score was 7 of 10 compared with the postoperative pain score of 2 of 10. In conclusion, the AIN can be used as a first-choice motor target for all peripheral sensory neuromas around the wrist for the following reasons: first, it can be reached by the peripheral sensory nerves around the wrist; second, the pronator quadratus muscle is expandable; and third, the AIN can be taken with a long proximal tail for flexible coaptation with the peripheral sensory nerves.

Abstract
Liposuction is generally recognized as a safe medical procedure. However, it is important to acknowledge the potential for complications during and after the operation. Although rare, the occurrence of iatrogenic liver perforation following liposuction is viewed as a serious complication, necessitating immediate and attentive medical care. We report a case of a 42-year-old female who underwent liposuction and presented with abdominal pain 3 days later. Elevated liver enzymes and imaging revealed an active bile leak from the right liver lobe. Exploratory laparotomy confirmed a penetrating injury, leading to multiple washout surgeries. After a 3-month hospital stay, including intensive care, the patient fully recovered upon discharge following abdominal wound closure. Despite considering liposuction procedures safe due to the associated overall low risk rates, it can lead to life-threatening complications such as hollow viscus or solid organ injury. The treatment for such complications can either be surgical or nonsurgical, depending on the patient's presentation and diagnosis. To promptly identify and address any complication postsurgery, close monitoring of patients postoperatively is necessary. Level of Evidence 5

Abstract
The deep branch of the ulnar nerve (DBUN) is a pure motor nerve. It passes through a hypothenar fibromuscular tunnel and courses radially on the interossei surface. The DBUN is not frequently considered during hand fracture surgery, despite the anatomical course of the nerve in close relation to the carpal and metacarpal bones, which makes it vulnerable to penetrating injury and being injured during hand surgery fixations. In this article, we describe a case of DBUN injury after percutaneous pinning of the fourth and fifth metacarpal bone fractures complicated by intrinsic muscle wasting of the hand that was treated with neuroma excision and sural nerve graft. We present the case of a 36-year-old man, who had a fracture of the base of the fourth and fifth metacarpal bones, which was treated with multiple K-wires. A few months later, the patient presented with weak abduction/adduction of the three ulnar fingers and prominent wasting in the intrinsic muscles of the hand. On hand exploration, a 2-cm neuroma was found along the course of the DBUN distal to the hypothenar fibromuscular tunnel, which was treated by neuroma excision and nerve grafting. Fractures of the fourth and fifth metacarpals and carpometacarpal dislocations are very common and are often treated surgically. To fix these fractures, awareness of the DBUN course in the hand and its proximity to the carpal and metacarpal bones is important. High caution should be taken during percutaneous pinning by inserting K-wires under radiological guidance, minimizing pining attempts and limiting pin tip protrusion to 1-2 mm.

Abstract
For the last several decades, semiconducting materials and nanocomposites have received a lot of interest in generating highly efficient photocatalysts to destroy organic pollutants and eradicate bacteria. This study uses a simple deposition and precipitation approach at ambient temperature to create a unique and efficient AgI-CdO heterojunction. DRS, IR, SEM, EDS, XRD, EIS, and TEM were utilized to identify the material. SEM and TEM investigation depict the completely spherical, hexagonal forms and zigzag cubes for synthesized AgI-CdO. The EDX spectra reveal the presence of Ag, I, Cd, and O elements without impurity peaks showing that the prepared samples are highly pure. The activity of the synthesized materials was tested by degrading two different chromophoric dyes and a drug derivative (paracetamol) in an aqueous suspension under visible light. In addition, the activity of the most active catalyst was compared with Degussa P25, Fenton's reagent, and under sunlight for degradation of MB and RhB under similar conditions. Photolysis of paracetamol was also looked at using HPLC to identify intermediates formed in the photo-oxidation process. In addition, antibacterial activity was also investigated with the synthesized CdO-AgI nanocomposite in vitro against human pathogenic bacterial strains and compared with that of pure materials like AgI and standard ampicillin. The results showed excellent activity with the composite material, which could be due to the higher surface areas and the interactions between AgI and CdO nanoparticles. Quenching investigations revealed O2˙- and holes are principal reactive species. A viable photocatalytic degradation mechanism for organic pollutant elimination over the AgI-CdO nanocomposite has been sketched out based on the obtained results.

Abstract
Background: The Pulvertaft weave was described more than 50 years ago and is still used in tendon transfers. The aim of this study was to evaluate the strength of a modified core suture Pulvertaft weave technique and compare it to the original Pulvertaft weave traditionally used in tendon transfer surgery. Methods: 12 extensor pollicis longus tendons and extensor indices proprius tendons were harvested from fresh frozen cadavers. Six Pulvertaft weaves were performed using FiberWire 4.0 and six core suture tendon weave were performed using FiberLoop 4.0. Biomechanical analysis was performed and stifness, first failure load and ultimate failure load were measured for both set of repairs. Results: The stiffness of the core suture tendon repair (9.5 N/mm) was greater than that of the Pulvertaft repair (2.5 N/mm) The first failure load of the core suture tendon repairs (68.9 N) was greater than the Pulvertaft repairs (19.2 N) and the ultimate failure load of the core suture tendon repairs (101.8 N) was greater than the Pulvertaft repairs (21.9 N). All of these differences were statistically significant. Conclusions: The core suture Pulvertaft weave is a modification to the Pulvertaft weave used in tendon transfers. The results of this cadaveric study suggest it is 5 times stronger than the traditional Pulvertaft repair, potentially allowing it to be used with early active motion protocols after tendon transfers.

Abstract
This is a 39-year-old male, fell from a bike, left wrist with trans-styloid perilunate fracture dislocation that underwent open reduction internal fixation, 20 months after surgery the patient developed avascular necrosis of the lunate, final wrist fusion was performed secondary to the arthritic changes on the wrist. Anatomic dissection was performed and vascularity of the lunate was identified, its origin is from the volar palmar arch, when dislocated palmarly and more than 90 degrees the vessel is still intact. More than 512 patients with perilunate dislocation and perilunate fracture dislocation are included we identified in the literature transient avascular necrosis of the lunate in nine and seventeen of pure avascular necrosis of the lunate. Concluding that avascular necrosis of the lunate after perilunate dislocation or perilunate fracture dislocation is an infrequent finding especially when the volar ligaments are intact.

Abstract
Background: Femur is the most fractured long bone in the body that often necessitates surgical fixation; however, data on the impact of the mechanism of injury (MOI), age, and timing of intervention are lacking in our region of the Arab Middle East. We aimed to describe the patterns, management, and outcome of traumatic femoral shaft fractures. Methods: A retrospective descriptive observational study was conducted for all trauma patients admitted with femoral shaft fractures between January 2012 and December 2015 at the only level 1 trauma center and tertiary hospital in the country. Data were analyzed and compared according to the time to intervention (intramedullary nailing; IMN), MOI, and age groups. Main outcomes included in-hospital complications and mortality. Results: A total of 605 hospitalized cases with femur fractures were reviewed. The mean age was 30.7 ± 16.2 years. The majority of fractures were unilateral (96.7%) and 91% were closed fractures. Three-fourths of fractures were treated by reamed intramedullary nailing (rIMN), antegrade in 80%. The pyriform fossa nails were used in 71.6% while trochanteric entry nails were used in 28.4%. Forty-five (8.9%) fractures were treated with an external fixator, 37 (6.1%) had conservative management. Traffic-related injuries occurred more in patients aged 14–30 years, whereas fall-related injuries were significantly higher in patients aged 31–59. Thirty-one patients (7.8%) had rIMN in less than 6 h post-injury, 106 (25.5%) had rIMN after 6–12 h and 267 (66.8%) had rIMN after more than 12 h. The implant type, duration of surgery, DVT prophylaxis, in-hospital complications, and mortality were comparable among the three treatment groups. Conclusions: In our center, the frequency of femoral fracture was 11%, and it mainly affected severely injured young males due to traffic-related collisions or falls. Further multicenter studies are needed to set a consensus for an appropriate management of femur fracture based on the MOI, location, and timing of injury.

Abstract
Epithelioid sarcoma is a rare soft tissue sarcoma. It is a slow-growing neoplasm, which usually presents as a painless mass in the extremities and typically grows along deep dermal and subcutaneous planes. In contrast to other types of sarcoma, it has a strong tendency for nodal metastasis and local metastasis adjacent to the primary lesion within the affected limb. In this article, we present a case of chronic traumatic ulcer in the upper extremity in an adolescent male that was subsequently diagnosed as epithelioid sarcoma, which is a very unusual mode of presentation of this particular tumour. The patient was treated with wide local excision and reconstruction with a free flap. Histopathological examination and immunochemistry studies confirmed the diagnosis and the patient underwent radiotherapy post-operatively as a part of the treatment regime. His post-treatment period was unremarkable, and he was put on regular surveillance to monitor the development of any signs of disease recurrence. Patients with epithelioid sarcomas often present late due to the slow-growing nature of the tumour. Unusual presentations like this will further delay the diagnosis and treatment, which will eventually worsen the prognosis. Awareness of such presentations can encourage primary care physicians to make early referrals to experts, which, in turn, may help the patients get early treatment and have a better prognosis.

Abstract
Background Psychological distress following traumatic injury can influence the patient health, well-being and quality of life; however, this impact may partly vary according to the type and severity of injury. We aimed to study the predominant distress causing cluster and individual symptoms of Post-Traumatic Stress Disorders (PTSD) at the clinical and subthreshold level in patients with traumatic injuries, based on the mechanism of injury (MOI). Methods A hospital based cross-sectional study was conducted at a Level 1 Trauma Center utilizing PTSD Checklist to diagnose PTSD after one month of the traumatic event. All patients suffering from psychological distresses were assessed by a clinical psychologist in the trauma section. PTSD diagnostic criteria from DSM-5 were used to classify the patients. The inclusion criteria comprised of adult trauma patients who were directly involved in traumatic injuries and admitted under the Trauma Surgery services for a minimum of one day; have ability to provide written informed consent and can be assessed with the PCL-5 checklist after 4 weeks post-injury. Results Two hundred patients completed PCL-5 checklist, of them 26 (13.0%) were positive for PTSD and 174 (87%) had subthreshold scores. The mean age of participants was 34.4±11.8 years and males constituted 90.5%. Road traffic injury (RTI) was most the frequent injury mechanism (59%). PTSD positive patients with RTI, fall of heavy objects, pedestrian injury and assaults had highest average scores on clusters of negative alterations in mood and cognitions (16.9, 18.0, 18.5, 17.0 respectively), followed by hyperarousal. Symptom of always being on the guard and having repeated unwanted or disturbing memories of the incident, was reported by nearly 100% PTSD positive patients. Patients with subthreshold scores also reported distressing symptoms on all four clusters of PTSD. Conclusions Patients with different MOI showed a broad range of psychological problems with respect to symptom clusters. Negative alteration in mood and cognition followed by hyperarousal caused higher level of distress in patients post traumatic injuries. Subthreshold symptoms of PTSD are more common and deserve more attention.

Abstract
Background A global rise in multidrug-resistant (MDR) nosocomial infections has led to a significant increase in morbidity and mortality. MDR Gram-negative bacteria (GNB) are recognised for rapidly developing drug resistance. Despite Pseudomonas aeruginosa being the second most common GNB isolated from healthcare associated infections, the magnitude of MDR P. aeruginosa (MDR-PA) has not been evaluated in Qatar. Aim To assess the prevalence and antimicrobial susceptibility patterns of MDR-PA from 5 major hospitals in Qatar. Methods A total of 2533 P. aeruginosa clinical isolates were collected over a one-year period. MDR-PA was defined as resistance to at least one agent of ≥ 3 antibiotic classes. Clinical and demographic data were collected prospectively. Findings The overall prevalence of MDR-PA isolates was 8.1% (205/2533); the majority of isolates were from patients exposed to antibiotics during 90 days prior to isolation (85.4 %, 177/205), and the infections were mainly hospital-acquired (95.1%, 195/205) with only 4.9% from the community. The majority of MDR-PA isolates were resistant to cefepime (96.6%, 198/205), ciprofloxacin, piperacillin/tazobactam (91%, 186/205), and meropenem (90%, 184/205). Patient comorbidities with MDR-PA were diabetes mellitus (47.3%, n=97), malignancy (17.1%, n=35), end-stage renal disease (13.7%, n=28) and heart failure (10.7%, n=22). Conclusion There was a significant prevalence of MDR-PA in Qatar, primarily from healthcare facilities and associated with prior antibiotic treatment. There was an alarming level of antimicrobial resistance to carbapenems. Our results are part of a national surveillance of MDR to establish effective containment plans.

Abstract
BACKGROUND Desmoid tumors are fibrous neoplasms that originate from the musculoaponeurotic structures in the body. Abdominal wall desmoid tumors are rare, but they can be locally aggressive, with high incidence of recurrence. These tumors are more common in young, fertile women. They frequently occur during or after pregnancy. CASE REPORT We present the case of a 63-year-old post-menopausal woman with a desmoid tumor of the anterior abdominal wall. She had no relevant family history. During abdominoplasty, an incidental mass was excised and biopsied, and was identified as a desmoid tumor with free margins. One year later, the patient presented with vague abdominal discomfort and feeling of heaviness. An incision was made through the previous abdominoplasty scar to maintain the aesthetic outcome. A large mass, arising from the abdominal wall and extending intra-abdominally, was excised and was determined to be a recurrent desmoid tumor. CONCLUSIONS Recurrent anterior abdominal wall desmoid tumors in post-menopausal women are rare and locally aggressive, with a high risk of recurrence. During abdominal wall repair in abdominoplasty, desmoid tumor filaments might seed deep intra-abdominally. Therefore, it is necessary to take adequate safe margins before abdominal wall repair. Post-operatively, surgeons should keep a high index of suspicion for tumor recurrence.

Abstract
INTRODUCTION There is no consensus yet on the impact of timing of femur fracture (FF) internal fixation on the patient outcomes. This meta-analysis was conducted to evaluate the contemporary data in patients with traumatic FF undergoing intramedullary nail fixation (IMN). METHODS English language literature was searched with publication limits set from 1994 to 2016 using PubMed, Scopus, MEDLINE (OVID), EMBASE (OVID), Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL). Studies included randomized controlled trials (RCTs), prospective observational or retrospective cohort studies, and case-control studies comparing early versus late femoral shaft fractures IMN fixation. Variable times were used across studies to distinguish between early and late IMN, but 24 h was the most frequently used cutoff. The quality assessment of the reviewed studies was performed with two instruments. Observational studies were assessed with the Newcastle-Ottawa Quality Assessment Scale. RCTs were assessed with the Cochrane Risk of Bias Tool. RESULTS We have searched 1151 references. Screening of titles and abstracts eliminated 1098 references. We retrieved 53 articles for full-text screening, 15 of which met study eligibility criteria. CONCLUSIONS This meta-analysis addresses the utility of IMN in patients with FF based on the current evidence; however, the modality and timing to intervene remain controversial. While we find large pooled effects in favor of early IMN, for reasons discussed, we have little confidence in the effect estimate. Moreover, the available data do not fill all the gaps in this regard; therefore, a tailored algorithm for management of FF would be of value especially in polytrauma patients.

Abstract
Rare earth metal doping into semiconductor oxides is considered to be an effective approach to enhance photocatalytic activity due to its ability to retard the electron–hole pair recombination upon excitation. Herein, we report the synthesis of different rare earth metal (La, Nd, Sm and Dy)-doped ZnO nanoparticles using a facile sol–gel route followed by evaluation of their photocatalytic activity by studying the degradation of methylene blue (MB) and Rhodamine B (RhB) under UV-light irradiation. Different standard analytical techniques were employed to investigate the microscopic structure and physiochemical properties of the prepared samples. The formation of the hexagonal wurtzite structure of ZnO was established by XRD and TEM analyses. In addition, the incorporation of rare earth metal into ZnO is confirmed by the shift of XRD planes towards lower theta values. All metal doped ZnO showed improved photocatalytic activity toward the degradation of MB, of which, Nd-doped ZnO showed the best activity with 98% degradation efficiency. In addition, mineralization of the dye was also observed, indicating 68% TOC removal in 180 min with Nd-doped ZnO nanoparticles. The influence of different operational parameters on the photodegradation of MB was also investigated and discussed in detail. Additionally, a possible photocatalytic mechanism for degradation of MB over Nd-doped ZnO nanoparticles has been proposed and involvement of hydroxyl radicals as reactive species is elucidated by radical trapping experiments. In this study, we compared the photocatalytic activity of sol–gel derived rare earth metal (La, Nd, Sm and Dy)-doped ZnO photocatalysts by studying the degradation of MB and RhB under UV light irradiation.![]()

Abstract
INTRODUCTION Multidrug-resistant Pseudomonas aeruginosa (MDR-PA) is an important and growing issue in the care of patients with cystic fibrosis (CF), and a major cause of morbidity and mortality. OBJECTIVE The objective of the study was to describe the frequency of MDR-PA recovered from the lower respiratory samples of pediatric and adult CF patients, and its antibiotic resistance pattern to commonly used antimicrobial agents including β-lactams, aminoglycosides, and fluoroquinolones. MATERIALS AND METHODS The lower respiratory isolates of P. aeruginosa were obtained from inpatients and outpatients CF clinics from a tertiary care teaching hospital for the period from October 2014 to September 2015. The identification and antimicrobial susceptibility for all the isolates were performed by using the BD Phoenix™ and E-test in compliance with Clinical and Laboratory Standards Institute (CLSI) guidelines. RESULTS A total of 61 P. aeruginosa samples were isolated from thirty CF patients from twenty families. Twelve sputum samples were positive for MDR-PA (seven nonmucoid and five mucoid isolates) from five CF patients (five families) with moderate-to-very severe lung disease given MDR-PA frequency of 19.7%. The median age of the study group was 20 (range 10-30) years. Three CF patients were on chronic inhaled tobramycin and two on nebulized colistin. The antimicrobial patterns of isolates MDR-PA showed the highest rate of resistance toward each gentamycin, amikacin, and cefepime (100%), followed by 91.7% to ciprofloxacin, 75% to tobramycin, 58.3% to meropenem, and 50% to piperacillin-tazobactam. None of the isolates were resistant to colistin during the study period. CONCLUSION The study results emphasize that the emergence of a significant problem in the clinical isolates of P. aeruginosa in CF patients that dictate appropriate attention to the antibiotic management after proper surveillance.

Abstract
Intravascular glomus tumor in the forearm is very rare and usually presents with persistent pain and focal tenderness. The diagnosis of this condition can be easily missed or delayed. There is no successful treatment so far other than surgical excision in most of cases. We presented a 45-year-old female presented with intravascular glomus tumor in her left forearm. The swelling was excised and the post-operative course was uneventful. Intravascular glomus tumor of the forearm is extremely rare and the persistent pain and tenderness are very suspicious. Diagnostic imaging may not be indicated in every case.

Abstract
BACKGROUND Porto-mesenteric venous thrombosis (PMVT) is an infrequent but severe surgical complication developing in patients who underwent laparoscopic bariatric surgery (sleeve gastrectomy). Herein, we describe the clinical presentation, management, and outcome of 3 rare cases of PMVT after laparoscopic sleeve gastrectomy (LSG), successfully treated at our center. CASE REPORT All patients developed PMVT post-LSG and presented with diffused abdominal pain, nausea, and vomiting. Computed tomography (CT) of the abdomen confirmed the diagnosis of portal vein thrombosis. Two patients were treated conservatively with anticoagulation and thrombolytic therapy and the third patient required operative intervention with bowel resection. CONCLUSIONS PMVT is a rare presentation after LSG, which requires early diagnosis and management. Conservative management through anticoagulants and thrombolytic therapy is quite effective and, if indicated, should always be considered as the primary treatment option.

Abstract
BACKGROUND Spontaneous rupture of the urinary bladder (SRUB) secondary to alcohol intoxication is an uncommon presentation with high morbidity and mortality. Herein, we reported a rare case of spontaneous atraumatic rupture of the urinary bladder due to alcohol intoxication. CASE REPORT A 45-year-old Sri Lankan man presented with drowsiness, diffuse abdominal pain, vomiting with odor of alcohol, and urinary retention 24 hours prior to the index admission. CT cystogram confirmed the urinary bladder rupture at the dome, which was repaired through exploratory laparotomy. CONCLUSIONS An SRUB patient with alcohol abuse often presents with non-specific symptoms due to absence of a traumatic event, which results in missed or delayed-diagnosis. Early diagnosis and management of SRUB is crucial for uneventful recovery.

Abstract
BACKGROUND Morning report, a case-based conference that allows learners and teachers to interact and discuss patient care, is a standard educational feature of internal residency programs, as well as some other specialties. OBJECTIVE Our intervention was aimed at enhancing the format for morning report in our internal medicine residency program in Doha, Qatar. INTERVENTION In July 2011, we performed a needs assessment of the 115 residents in our internal medicine residency program, using a questionnaire. Resident input was analyzed and prioritized using the percentage of residents who agreed with a given recommendation for improving morning report. We translated the input into interventions that enhanced the format and content, and improved environmental factors surrounding morning report. We resurveyed residents using the questionnaire that was used for the needs assessment. RESULTS Key changes to the format for morning report included improving organization, adding variety to the content, enhancing case selection and the quality of presentations, and introducing patient safety and quality improvement topics into discussions. This led to a morning report format that is resident-driven, and resident-led, and that produces resident-focused learning and quality improvement activities. CONCLUSIONS Our revised morning report format is a dynamic tool, and we will continue to tailor and modify it on an ongoing basis in response to participant feedback. We recommend a process of assessing and reassessing morning report for other programs that want to enhance resident interest and participation in clinical and safety-focused discussions.

Abstract
INTRODUCTION Blunt esophageal injuries secondary to external air compression of anterior chest and abdomen complicated with esophageal perforation are uncommon events associated with worse outcomes. PRESENTATION OF CASE We reported a rare case of esophageal perforation following an external air-compression injury along with the relevant review of literatures. The patient presented with chest pain and shortness of breath and was managed with tube thoracostomy, followed by thoracotomy and eventually with temporary endoscopic stenting. DISCUSSION In such trauma case, the external pressurized air forms a shock wave which usually directed to the hollow viscus. Patients with external air-compression injury presented with chest pain and pneumothorax should be suspected for esophageal perforation. CONCLUSION High index of suspicion is needed for early diagnosis of esophageal perforation after blunt trauma. Appropriate drainage, antibiotic and temporary endoscopic esophageal stenting may be an optimal approach in selected patients, especially with delayed diagnosis.

Abstract
A novel polyaniline based composite cation exchange material has been synthesized by simple chemical route and characterized on the basis of sophisticated techniques. XRD and SEM analyses reveal the amorphous morphology of the material. The partition coefficient studies of different metal ions on the material were performed in DMW and diverse concentrations of HClO4 solutions. On the basis of high Kd values some significant separations of heavy toxic metal ions were achieved from synthetic mixtures as well as tap water samples by using columns of this exchanger. For the optimum adsorption of dye on the material, the effect of various parameters along with Langmuir and Freundlich adsorption isotherm were examined. The observed result of conducting measurement indicates that the material covers semiconductor range. The photochemical degradation of industrial dyes and antimicrobial activity were also investigated which show significant results than some of the known antibiotics. On the basis of good ion exchange capacity along with photochemical degradation and microbial activity, polyanilineTi(IV)arsenophosphate can be considered as an excellent conducting material for the treatment metal ions and degradation of organic pollutants.

Abstract
Semiconductor-mediated hydrogen peroxide-assisted photocatalytic degradation of a selected herbicide, Bentazone (1) has been investigated in aqueous suspensions of TiO2 under a variety of conditions. The degradation was studied by monitoring the depletion in total organic carbon content as a function of irradiation time. The degradation kinetics was investigated under different conditions such as type of TiO2 (Anatase/Anatase-Rutile mixture), reaction pH, catalyst dosage and hydrogen peroxide (H202) concentration. The degradation rates were found to be strongly influenced by all the above parameters. Titanium dioxide Degussa P25 was found to be more efficient as compared with other two commercially available TiO2 powders like Hombikat UV100 and PC500 from Millennium Inorganic Chemicals. Gas Chromatography-Mass Spectrometry (GC-MS) analysis of the irradiated mixture of Bentazone (1) indicates the formation of several intermediate products which have been characterized on the basis of molecular ion/mass fragmentation pattern and also on comparison with the National Institute of Standards and Technology (NIST) library. Plausible mechanism for the formation of different products during photocatalytic treatment of Bentazone in the presence of TiO2 has been proposed. The use of H202 substantially increased the efficiency of TiO2 photocatalytic degradation.

Abstract
This paper deals with the study of photocatalyzed degradation of an insecticide, Thiamethoxam in aqueous suspension of TiO2. The adsorption of Thiamethoxam on TiO2 surface under dark conditions was also investigated in order to find out equilibrium adsorption constant. The degradation kinetics was studied using spectrophotometric method under various conditions such as substrate concentration, type of catalyst, catalyst dosage, pH, and in the presence of electron acceptors such as hydrogen peroxide, potassium bromate, and ammonium persulphate under continuous purging of atmospheric oxygen, and the degradation rates were found to be strongly influenced by these parameters. The results manifested that the photocatalysis of Thiamethoxam follows pseudo-first-order kinetics. The toxicity assessments of the irradiated samples were carried out using human erythrocytes as a model system under in vitro conditions. GC-MS study showed the formation of several intermediate products which were characterised based on their molecular mass and mass fragmentation pattern. A probable mechanism for the formation of various products formed during the photocatalytic process of Thiamethoxam was also proposed.
