Correlation of brain-derived neurotrophic factor with severity of depression and treatment response.

Background: Brain-derived neurotrophic factor (BDNF) is a modulator of neuroplasticity in the brain. It plays an important role in the pathophysiology of depression through the stress pathway. The information about correlation of BDNF levels with depression severity and treatment response in Indian population is scarce. Methods: Consecutive 60 never treated cases with depression reporting to a large tertiary care psychiatry unit and 60 healthy matched controls from 01 January 2016 to 31 December 2016 were enrolled for study. Sociodemographic data were collected. Diagnosis of depression was carried out as per International Classification of Diseases-10th revision (ICD-10) diagnostic criteria for research. The Hamilton Rating Scale for Depression (HRSD) was administered and accordingly scored. Venous blood for BDNF levels was collected from all cases and controls. Cases were reassessed after 04 weeks of treatment with HRSD and BDNF levels. Results: The mean level of serum BDNF among cases (18.56 ng/ml) was found to be reduced significantly as compared with healthy controls (32.41 ng/ml). The mean serum BDNF level (18.56 ng/ml) in never treated cases was significantly negatively correlated with the median clinical HRSD score (18.5). There was a significant increase in the mean level of serum BDNF after antidepressant treatment. Conclusion: The study has revealed statistically significant low levels of serum BDNF in cases not exposed to treatment with depression compared with healthy controls. There was significant negative correlation of levels of serum BDNF with depression severity. The levels of serum BDNF significantly increased after four weeks of treatment.

Efficacy of chitosan-coated textile waste biochar applied to Cd-polluted soil for reducing Cd mobility in soil and its distribution in moringa (Moringa oleifera L.).

Soil pollution with Cd has promoted serious concerns for medicinal plant quality. Amending Cd-polluted soils with textile waste biochar (TWB) coated with natural polymers can lower Cd bioavailability in them and reduce associated environmental and human health risks. In this study, we explored the impacts of solely applied TWB, chitosan (CH), their mix (TWB + CH) and TWB coated with CH (TBC) in Cd-polluted soil on Cd distribution in moringa (Moringa oleifera L.) shoots and roots as well as plant-available Cd in soil. Moreover, amendments effects on plant growth, dietary quality, and antioxidative defense responses were also assessed. Results revealed that the addition of TWB, CH, and TWB + CH in Cd-polluted soil reduced Cd distribution in shoots (56%, 66%, and 63%), roots (41%, 48%, and 45%), and plant-available Cd in soil (38%, 52%, and 49%), compared to control. Interestingly, the TBC showed significantly the topmost response for reducing Cd concentrations in shoots, roots, and soil by 73%, 54%, and 58%, respectively, relative to control. Moreover, amending Cd-polluted soil with TWB, CH, and TWB + CH depicted significantly better effects on plant growth, dietary quality, and activities of soil enzymes but the topmost response was observed with TBC treatment. Compared with control, TBC improved plant growth parameters: shoot length (81%), root length (90%), shoot fresh weight (60%), root fresh weight (76%), shoot dry weight (75%), root dry weight (68%) contents of chlorophyll-a (42%) and chlorophyll-b (74%), and soil enzyme activities: urease (130%), catalase (138%), protease (71%), cellobiohydrolase (45%), acid phosphatase (34%), peroxidase (60%), ß-glucosidase (152%), chitinase (62%), and phosphomonoesterase (139%). Furthermore, TBC treatment arrested Cd-induced oxidative stress via escalating the activities of antioxidant enzymes as well as improved moringa dietary parameters (protein, tannins, lipids, alkaloids, saponins, terpenoids, flavonoids, and tocopherols contents). Such findings suggest that the TBC has an immense perspective to remediate Cd-polluted soils and prevent human health risks associated with Cd exposure through the diet.

Promoting the productivity and quality of brinjal aligned with heavy metals immobilization in a wastewater irrigated heavy metal polluted soil with biochar and chitosan.

Depleting aquifers, lack of planning and low socioeconomic status of Pakistani farmers have led them to use wastewater (WW) for irrigating their crops causing food contamination with heavy metals and ultimately negative effects on human health. This study evaluates the effects of chitosan (CH) and biochar (BC) on growth and nutritional quality of brinjal plant together with in situ immobilization of heavy metals in a soil polluted with heavy metals due to irrigation with wastewater (SPHIW) and further irrigated with the same WW. Both CH and BC were applied at three different rates i.e. low rate [(LR), BC0.5%, CH0.5% and BC0.25%+CH0.25%], medium rate [(MR), BC1%, CH1% and BC0.5%+CH0.5%] and high rate [(HR), BC1.5%, CH1.5% and BC0.75%+CH0.75%]. Result revealed that brinjal growth, antioxidant enzymes, and fruit nutritional quality significantly improved from LR to HR for each amendment, relative to control. However, these results were more prominent with BC alone and BC+CH, compared with CH alone at each rate. Similarly, with few exceptions, significant reduction in Ni, Cd, Co, Cr and Pb concentrations in the root, shoot and fruit were found in sole CH treatment both at LR and MR but in both CH and BC+CH treatments at HR, relative to control. Interestingly, the concentrations of Fe in the roots, shoots and fruit were more pronounced at BC treatments relative to CH and BC+CH treatments at each rate, compared to control. Overall, the BC+CH treatment at HR was the most effective treatment for in situ immobilization of heavy metals in SPHIW and further irrigated with the same WW, compared to rest of the treatments. This study indicates that BC0.75%+CH0.75% treatment can be used to reduce mobility and bioavailability of heavy metals in SPHIW and facilitates plant growth by improving the antioxidant system. However, the feasibility of BC0.75%+CH0.75% treatment should also be tested at the field scale.

Dural Tears In Patients With Depressed Skull Fractures.

BACKGROUND: The presence of skull fracture in patients sustaining traumatic brain injury is an important risk factor for intracranial lesions. Assessment of integrity of dura in depressed skull fracture is of paramount importance because if dura is torn, lacerated brain matter may be present in the wound which needs proper debridement followed by water tight dural closure to prevent meningitis, cerebral abscess, and pseudomeningocoele formation. The objective of this study was to determine the frequency of dural tear in patients with depressed skull fractures. METHODS: This cross-sectional study was conducted at Department of Neurosurgery Ayub Teaching Hospital Abbottabad. All the patients of either patients above 1 year of age with depressed skull fracture were included in this study in consecutive manner. Patients were operated for skull fractures and per-operatively dura in the region of depressed skull fracture was closely observed for any dural tear. The data were collected on a predesigned pro forma. RESULTS: A total of 83 patients were included in this study out of which 57 (68.7%) were males and 26 (31.3%) were females. The age of the patients ranged from 1-50 (mean 15.71±13.49 years). Most common site of depressed skull fracture was parietal 32 (38.6%), followed by Frontal in 24 (28.9%), 21(25.3%) in temporal region, 5(6.0%) were in occipital region and only 1 (1.2%) in posterior fossa. Dural tear was present in 28 (33.7%) patients and it was absent in 55 (66.3%) of patients. CONCLUSIONS: In depressed skull fractures, there are high chances of associated traumatic dural tears which should be vigilantly managed.

Decompressive Craniectomy For Acute Subdural Haematoma With Expansile Duraplasty Versus Dural-Slits.

BACKGROUND: Traumatic subdural hematoma is one of the lethal injuries to brain. Various surgical techniques are used to evacuate the acute subdural hematoma. The hematoma evacuation can either be done by opening of dura by multiple slits or by opening of dura in single large c shape and then doing the expansile duraplasty. Present study aimed to compare both these techniques. METHODS: This randomized control study was conducted in department of neurosurgery, Ayub Medical College, Abbottabad from July 2011 to July 2013. A total of 59 patients were included in this study, which were randomly allocated in two groups (i.e., group A and group B) for decompressive craniectomy. Thirty-one patients were operated by craniectomy with full dural flap opening (Group A), and 28 patients were operated by craniectomy with multidural-slits (Group B). Glasgow Outcome score (GOS) at 6 weeks after the surgery was used to determine the outcome. RESULTS: Mean age of the patients was 33.4±12.8 years. Majority were males. In group A 51.6 % (16) of the patients survived out of which a favourable outcome (GOC 3-5) was observed in 41.9% of the patients, and 9.1% of patients ended up in vegetative state. While in group B 46.4% (13) of the patients survived among which favourable outcome was seen in 39.3% of patients and 7.1% of patients ended up in vegetative state. The difference in outcome measure is insignificant. CONCLUSIONS: There was no statistically significant difference among the two groups as regards the mortality, GOS, frequency of complications and hospital. While the duration of surgery was significantly shorter in patients operated with dural slits.

Comparison Of Efficacy Of Phenytoin And Levetiracetam For Prevention Of Early Post Traumatic Seizures.

BACKGROUND: The incidence of early post-traumatic seizures after civilian traumatic brain injury ranges 4-25%. The control of early post-traumatic seizure is mandatory because these acute insults may add secondary damage to the already damaged brain with poor outcome. Prophylactic use of anti-epileptic drugs have been found to be have variable efficacy against early post-traumatic seizures. The objective of this study was to compare the efficacy of Phenytion and Levetiracetam in prevention of early post-traumatic seizures in moderate to severe traumatic brain injury. METHODS: This randomized controlled trial was conducted in department of Neurosurgery, Ayub Medical College, Abbottabad from March, 2012 to March 2013. The patients with moderate to severe head injury were randomly allocated in two groups. Patients in group A were given phenytoin and patients in group B were given Levetiracetam. Patients were followed for one week to detect efficacy of drug in terms of early post traumatic seizures. RESULTS: The 154 patients included in the study were equally divided into two groups. Out of 154 patients 115 (74.7%) were male while 29 (25.3%) were females. Age of patients ranges from 7-48 (24.15±9.56) years. Ninety one (59.1%) patients had moderate head injury while 63 (40.9%) patients had severe head injury. Phenytoin was effective in preventing early post traumatic seizures in 73 (94.8%) patients whereas Levetiracetam effectively controlled seizures in 70 (90.95%) cases (p-value of .348). CONCLUSIONS: There is no statistically significant difference in the efficacy of Phenytoin and Levetiracetam in prophylaxis of early posttraumatic seizures in cases of moderate to severe traumatic brain injury.

RADIOLOGICAL OUTCOME OF TRANSPEDICULAR SCREWS FIXATION IN THE MANAGEMENT OF THORACOLUMBAR SPINE INJURY.

BACKGROUND: Traumatic fracture of the spine 'is a serious neurosurgical condition that has serious impact on the patient's quality of life. Thoracolumbar junction is the most common site of spinal injuries. The aims of management of thoracolumbar spinal fractures are to restore vertebral column stability, and to obtain spinal canal decompression. This ultimately leads to early mobilization of the patients. This study was conducted to compare preoperative and post-operative vertebral height, kyphotic angle and sagittal index in patients treated with pedicle screws and rods in thoracolumbar spine fractures. METHODS: This cross-sectional study was conducted in the department of Neurosurgery, Hayatabad Medical Complex, Peshawar from 1st. February 2010 to 31st. July 2011. A total 161 patients with unstable thoracolumber spine fracture were included in this study. In these patients fixation was done through transpedicle screws with rods. Anteroposterior and lateral views X-rays of thoracolumbar spine were done pre and post operatively. RESULTS: Out of 161 patients, 109 (67.7%) were males and 52 (32.3%) females. The age of patients ranged from 20 to 70 years (mean 42.2 years) with 71 (44.1%) in the age range of 31-40 years. Preoperative average vertebral height was 9.4194. mm while postoperative average was 19.642 mm. The mean kyphosis was 23.06 degrees preoperatively. Immediately after surgery the average correction of kyphosis was 9.45 degrees. The pre-operative average sagittal index was 19.38 degrees, which was reduced to an average 5.41 degrees post operatively. CONCLUSIONS: Transpedicular fixation for unstable thoraco-lumbar spinal fractures achieves a stable fracture segment with improvement of vertebral height, kyphotic angle and sagittal index. Hence, preventing the secondary spinal deformities.

FREQUENCY OF EXTRADURAL HAEMATOMA IN PATIENTS WITH LINEAR SKULL FRACTURE.

BACKGROUND: Apparently normal looking patients after traumatic brain injury can have serious neurological deterioration, and one of the common causes of such deterioration is extradural haematomas. This study was conducted to determine the frequency of extradural hematoma and common types of trauma leading to it among patients presenting with skull fracture due to head injury. METHODS: This cross-sectional study was conducted in the department of Neurosurgery Ayub Medical College, Abbottabad from June 2011 to June 2012. All patients who were suspected to have Skull fracture on X-ray skull, during the study period, were included in study after informed consent and later on CT-Scan brain was done to see for extradural hematoma. Findings were recorded on a predesigned pro fonna including demographic data, radiological findings and the type of head trauma. RESULTS: Out of 114 patients 85 (74.5%) were males and 29 (225.4%) were females. Age ranged from 2 to 70 years (18.23 +/- 16.5 years). Among these patients the most important cause of head injury was fall from height in 65 (57%), followed by road traffic accidents in 39 (34.2%), and assault in 10 (8.8%) patients. The most common site of fracture was parietal in 49 (43%) of patients, followed by frontal bone in 28 (24.6%) of patients, occipital bone in 24 (21.1%) of patients, and temporal bone in 23 (20.2%) of patients. Frequency of extradural hematoma among linear skull fracture was in 34 (29.8%) patients. Extradural hematoma was most common with parietotemporal linear skull fractures (73.5%). CONCLUSION: Extradural haematoma occurs commonly with linear skull fractures, so patients with linear skull fracture should be properly evaluated with CT brain.

MICROVASCULAR DECOMPRESSION FOR TRIGEMINAL NEURALGIA.

BACKGROUND: Trigeminal Neuralgia (TGN) is the most frequently diagnosed type of facial pain. In idiopathic type of TGN it is caused by the neuro-vascular conflict involving trigeminal nerve. Microvascular decompression (MVD) aims at addressing this basic pathology in the idiopathic type of TGN. This study was conducted to determine the outcome and complications of patients with idiopathic TGN undergoing MVD. METHODS: In a descriptive case series patients with idiopathic TGN undergoing MVD were included in consecutive manner. Patients were diagnosed on the basis of detailed history and clinical examination. Retromastoid approach with craniectomy was used to access cerebellopontine angle (CP-angle) and microsurgical decompression was done. Patients were followed up for 6 months. RESULTS: A total of 53 patients underwent MVD with mean age of 51.6±4.2 years and male predominance. In majority of cases (58.4%) both Maxillary and Mandibular divisions were involved. Per-operatively superior cerebellar artery (SCA) was causing the neuro-vascular conflict in 33 (62.2%) of the cases, anterior inferior cerebellar artery (AICA) in 6 (11.3%) cases, both CSA and AICA in 3 (5.6%) cases, venous compressions in only 1 (1.8%) patient and thick arachnoid adhesions were seen in 10 (18.9%) patients. Postoperatively, 33 (68%) patients were pain free, in 14 (26.45%) patients pain was significantly improved whereas in 3 (5.6%) patients there was mild improvement in symptoms. Three (5.6%) patients did not improve after the primary surgery. Cerebrospinal fluid (CSF) leak was encountered in 7 (13.2%) patients post-operatively, 4 (7.5%) patients developed wound infection and 1 (1.8%) patient developed aseptic meningitis. Three (5.6%) patients had transient VII nerve palsy while one patient developed permanent VII nerve palsy. CONCLUSION: MVD is a safe and effective surgical option for treating patients with idiopathic TGN with better surgical outcome and fewer complications.

Effect of size on the surgical management of pulmonary hydatid cyst.

BACKGROUND: Hydatid cyst disease is a parasitic disease caused Echinococcus granulosus. Hydatid cysts of 10 cm or greater in diameter are called "giant" cysts and traditionally have been considered to be more difficult to treat surgically often requiring pulmonary resection. In this study we reviewed our experience with pulmonary hydatid cysts. METHODS: This study was carried out in Thoracic surgery unit Lady Reading Hospital Peshawar, from 1st June 2007 to 31st May 2012. Patients admitted with intra-thoracic hydatid cysts were evaluated. Patients were divided into 2 groups, i.e., patients who had cysts < 10 cm (group A) and those who had large cysts which were 10 cm (group-B). Data regarding age, sex, symptoms, diagnostic procedures, anatomic location of cysts, surgical procedures, complications, and outcomes were collected and analysed. RESULTS: Total of 224 patients underwent hydatid cystectomy. Group A comprised 190 patients (85%), Group-B comprised 34 patients (15%). Large cysts were more common in younger patients. The most frequent complaints were cough, chest pain, and dyspnea. Patients with large cysts were more often symptomatic at presentation. In both groups, lower-lobe locations predominated. Parenchyma-saving operations were almost uniformly performed for each group; however, a higher percentage of patients in group B required anatomic resection (5.8% vs. 1%). Cystic rupture occurred more frequently in group-B than in group-A (26% vs. 12%). There were no deaths in either group, and the morbidity was 23 (12%) in (group-A) and 6 (17.6%) in (group- B). CONCLUSION: Large hydatid cysts of the lung occurred more often in younger patients and were more often symptomatic at presentation. Regardless of size, the cysts could usually be surgically treated without lung resection, and size did not appear to influence short-term post-perative outcomes.

Frequency of albuminuria in diabetic patients presenting with macrovascular complications.

BACKGROUND: Diabetes mellitus is major cause of morbidity and premature mortality from its long-term complications such as cardiovascular disease, blindness, renal failure, amputation and stroke. The study was conducted to determine the frequency of albuminuria in diabetic patients presenting with macro-vascular complications like myocardial infarction (MI) and stroke. METHODS: This descriptive study was conducted at Ayub Medical College, Abbottabad from December 2010 to May 2011. Total 88 diabetic patients admitted with macro-vascular disease were included in this study. The patients were subjected to two urine specimen's examination, one for routine examination for infection and dipstick analysis for albuminuria. Second was tested for albumin was tested in the urine. RESULTS: Out of 88 patients with a mean 47.12 ± 7.58 years, 39 (44.32%) were female while 49 (55.68%) were male. Overall albuminuria was detected in the urine of 81 out of total 88 patients (92%) when tested by heating method whereas it was detected in 41 (46.6%) cases by the dipstick method. CONCLUSION: Frequency of albuminuria is much.higher in diabetic population with macro-vascular complications; hence albumin in the urine of diabetic patient can be regarded as an indicator for impending macro-vascular complications of diabetes.

Frequency of cerebellopontine angle tumours in patients with trigeminal neuralgia. .

BACKGROUND: Though the classical type of trigeminal neuralgia is the most common type with the neurovascular conflict causing the symptoms, yet quite some patients have the secondary type of trigeminal neuralgia in which space occupying lesions are responsible for the symptoms. This study was conducted to determine the frequency of cerebellopontine angle tumours in patients presenting with complaints of trigeminal neuralgia. METHODS: This case series descriptive study was conducted in the department of Neurosurgery, Ayub Medical College, Abbottabad, from January 2009 to January 2012. It included patients who presented with symptoms of trigeminal neuralgia. Patients were subjected to further radiological investigation like Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) to look for secondary causes of trigeminal neuralgia. RESULTS: Among the 134 patients with age ranges 13-64 (51?4.3) years of age, 78(58.2%) were females and 56 (41.7%) were males. Frequency of cerebellopontine angle tumours in patients was 14 (10.4%), among them epidermoid was most common lesion being present in 10 (7.4%) of patients and accounted for 75% of Cerebellopontine Angle tumours in these patients. Meningioma and vestibular schwanoma accounted for 2(1.4%) cases each. In secondary trigeminal neuralgia mean age of onset of symptoms was 39.5±5.2 years as compared to classic trigeminal neuralgia which is 53±2.1 years. CONCLUSION: Trigeminal Neuralgia can be a typical symptom in cerebellopontine angle tumours like epidermoid, especially in young patients, so all the patients with trigeminal neuralgia should be investigated for lesion in cerebellopontine region.

Eventration of diaphragm in adults: eleven years experience.

BACKGROUND: Eventration of diaphragm is a congenital condition in which there is absence of muscle fibers in the diaphragm while maintaining all the anatomical attachments normally. Surgical treatment is warranted in symptomatic patients so as to reduce the abnormal ascent of diaphragm. The present study was conducted to analyse the perioperative outcome of thoracotomy in adult patients with diaphragmatic eventration. METHODS: This descriptive case series was carried out in Cardiothoracic Surgery-Unit, Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, Pakistan. Medical records of patients operated upon for eventration from June 2002 to June 2013 were reviewed. Patients of either gender, above 16 years who were operated for symptomatic eventrtaion were included in study. All the demographic data, presenting complaints, baseline and post-postoperative dyspnea grade, forced expiratory volume at 1 second (FEV1) and forced vital capacity (FVC) were recorded on predesigned pro forma and analysed using SPSS-16. RESULTS: A total of 38 adult patients underwent surgery for diaphragmatic eventration over the past 11 years in our unit out of which 29 (76%) were males and rest of 9 (24%) were females. Mean age of patients was 41.6±13.84 years. In 31 (81.5%) patients left side was involved. Majority of patients had a dyspnea grade-3 on presentation. Preoperative dyspnoea score (MRC), FEV1 and FVC values were 2.6±0.73, 63.5±13.3 and 67.2±14.6 respectively. Pre-operative and 6-months follow-up values of dyspnoea grade, FEV1 and FVC values showed statistically significant improvement. CONCLUSION: Our study showed that adult patients with symptomatic unilateral eventration of diaphragm significantly benefit from diaphragmmatic plication.

Efficacy of preoperative single dose antibiotic in patients undergoing mesh repair for inguinal hernia.

BACKGROUND: Inguinal hernia is the commonest type of external hernias. Lichtenstein mesh repair is the most favoured technique of inguinal hernia repair nowadays. It is tension free repair of weakened inguinal wall using polypropylene mesh. The present study was conducted to determine the efficacy of single dose antibiotic with placebo on patients undergoing inguinal hernia mesh repair. METHODS: This randomised controlled trial was carried out in the Department of General Surgery, Ayub Teaching Hospital, Abbottabad from January to December 2011. The study population included male patients presenting with primary unilateral inguinal hernia, above 18 years of age. Mesh repair was performed in all patients. The patients were randomly divided into two groups. Patients in group A were given a single dose of antibiotic before inguinal hernia mesh repair and patients in group B were given placebo before inguinal hernia mesh repair. Efficacy of antibiotic and placebo was accessed in terms of surgical site infections (SSIs). RESULTS: A total of 166 cases of inguinal hernia mesh repair patients were recorded during the study period. A total of 83 patients were recruited in each group. Surgical site infection was found in 6 (7.2%) in Group B it was 15 (18.1%). The difference being statistically significant (p = 0.036). CONCLUSION: Antibiotic prophylaxis is a preferred option for mesh plasty.

Lumbar disc herniation in patients with chronic backache.

BACKGROUND: Low back pain with or without lower extremity pain is the most common problem among chronic pain disorders with significant economic, social, and health impact. This study was conducted to determine the frequency of lumbar disc herniation and its different levels, among patients with chronic backache. METHODS: This cross sectional study was conducted in the department of Neurosurgery, Ayub Medical College Abbottabad from January 2011 to January 2013. All the patients presenting with chronic low backache of either gender above the age 14 years were included in the study. Magnetic resonance imaging (MRI) was done in all the patients included in the study to look for lumbar disc herniation. RESULTS: A total of 477 patients with chronic low backache were included in the study out of which 274 (57.4%) were males. Age of the patients ranged from 19 to 75 (39.92 +/- 12.31) years. Out of 477 patients 38 (7.9%) had significant radiological evidence of disc prolapse at lumbar vertebral levels, with 26 (9.5%) males and 12 (5.9%) females. Among these 38 patients with inter-vertebral disc, 20 (52.6%) of patients had disc herniation at L5-S1, 15 (39.5%) at L4-L5, 2 (5.26%) cases at L3-L4 level and only one case (2.6%) had the involvement of L2-L3 level. No cases of L1-L2 disc prolapse were found. CONCLUSION: Patients with chronic backache can have inter-vertebral lumbar disc prolapsed disease. Middle age group are more affected by lumbar disc disease especially at the lower lumbar regions.

Spectrum of trigeminal neuralgia.

BACKGROUND: Trigeminal neuralgia (TN) is a very painful condition characterized by paroxysmal shock like pain in the distribution of one or more branches of trigeminal nerve caused by neurovascular conflict at the root entry zone of trigeminal nerve. This study was conducted to analyse the demography and pattern of TN in our setup. METHODS: This descriptive study was conducted in the Oral Surgery unit, Department of Dentistry, Ayub Medical College. Abbottabad, from April 2009 to October 2011. A total of 117 patients were included in study by convenience (non probability) sampling technique. All the patients presenting with the clinical features of TN were included in study. RESULTS: Out of 117 cases, 49 (41.9%) were males and remaining 68 (58.1%) were females. Age of the patients ranged from 32-72 (53.90 +/- 10.21) years. Right side was involved in 63 patients (53.8%), while the left side was involved in 51 patients (43.60). In only three cases (2%) there was bilateral involvement. The maxillary division was involved in 68 cases (58.1%) and mandibular division was involved in 37 cases (31.6%). The most common site of involvement was infra-orbital, which was involved in 68 cases (58.11%). The next common site was the mental nerve which showed involvement in 35 cases (29.9%) followed by inferior alveolar nerve which was affected in 14 cases (12%). Thirty three (28.2%) patients were having mild pain. 54 (46.2%) patients having moderate, 21 (18%) patients with severe and 9 (7.7%) patients were having very severe pain. No patient in our study had a family history of TN. Among our patients 103 (88%) patients underwent dental extraction for the same pain. CONCLUSION: The incidence of TN is more in old age especially in females. TN is frequently misdiagnosed in with tooth ache, so there is need to educate the medical practitioners and masses in order to avoid un-necessary tooth extractions.

Mortality And Prognostic Factors In Patients Operated For Acute Epidural Hematoma.

Background: Epidural hematoma is one of the most common surgical emergencies encountered in neurosurgery. This study was conducted to determine the mortality and prognostic factors in patients operated for traumatic intracranial epidural hematoma in a resource-constrained setting from a developing country. Methods: This retrospective study was conducted in the Department of Neurosurgery at Ayub Teaching Hospital Abbottabad from 1st January 2019 to 31st Dec 2021. Inclusion and exclusion criteria were created. The medical record of 116 patients admitted and operated on for traumatic extradural hematoma was retrospectively reviewed. Information was recorded using a standardized structured questionnaire. The outcome was measured in terms of the Glasgow coma outcome score. Results: Out of 116 patients, 93 were male and 23 were female.19 (16.4%) patients were in the age range 0-5 years, 42 (36.2%) were in the age range 6-15, 35(31.0%) were in the age range 16-30, 11 (9.5%) were in the age range 31-45 years, 7 (6.0%) were in the age range 46-60 years while only one patient included in this study was above 60 years. Overall mortality was 4.3%. Mortality was higher in females and in those aged less than 5 years (3.4%). 4 out of 16 patients died with GCS less than 8, while none of the patients died when GCS was above 12. Mortality was significantly higher in the presence of associated lesions (4.4% vs. 0%) and anisocoria (2.6% vs.1.7%). Patients who operated within 6 hours of trauma resulted in better outcomes with a mortality rate of 0.0% and functional recovery of 57.8 % while for those who operated after 6 hours, mortality was significantly higher (4.3%) and functional recovery was significantly low (15.5%). Conclusion: Good surgical outcomes can be achieved with early operative intervention if indicated. Female gender, low preoperative GCS score, presence of pupillary dilatation, presence of associated lesions, delayed surgical intervention and age less than 5 years are significant predictors for poor outcomes.

Efficacy Of Prophylactic Intrawound Application Of Vancomycin Powder In Preventing Surgical Site Infections In Spinal Instrumentation Surgery.

BACKGROUND: Surgical site infection (SSI) is always a matter of utmost concern in cases of spinal instrumentation in low-income countries. This study was conducted to determine the efficacy of local intrawound application of vancomycin powder in reducing postoperative SSI following Thoracolumbar-Sacral spinal instrumentation. METHODS: This randomized controlled trial was done in the Department of Neurosurgery, Ayub Teaching Hospital Abbottabad from 1st July 2019 to 31st December 2021. Seventy-eight patients of either gender with an age range from 15 to 65 years, who were planned for posterior spinal instrumentation surgery (transpedicular screw fixation), were included in the study. Patients were divided into two equal groups, A (Vanco group) and B (control group). In addition to standard systemic prophylaxis, 1 gm of Vancomycin powder was applied over the implant in Group A patients. RESULTS: The mean age of the patients in Group A was 36±16.6 while the mean age of patients in the group was 33.7±15.9 years. A statistically significant reduction of surgical site infection was observed in those who received a prophylactic intra-wound application of vancomycin powder (Vanco group) (5.2%) compared to the control group (20.5%). CONCLUSIONS: Intrawound vancomycin powder administration significantly decreases SSI following spinal instrumentation surgeries. Patients at high risk of infection are highly recommended as a candidate for this technique.

Demographics of basal cell carcinoma and its surgical management.

BACKGROUND: Basal cell carcinoma (BCC) is the most common, slow growing epidermal skin tumour and an increase in its incidence has been noticed in the past decades. Different treatment options include surgical and non-surgical measures. Surgical options include surgical excision, cryosurgery, curettage, electrodessication and Mohs micrographic surgery. Non-surgical treatments options are 5-flourouracil, photodynamic therapy, immunomodulation and radiotherapy. This study was conducted to determine the demographics of facial BCC and its rate of incomplete excision and recurrence. METHODS: Clinically diagnosed facial BCCs were included in this prospective descriptive study. Tumours were excised with 3-5 mm clinically palpable safe margins and were sent for histopathological confirmation and margin clearance. All patients were followed for a minimum of two years to look for any recurrence. The demographic data, site, clinical presentation, size of the lesion, excision margins, reconstructive options, complications, histopathological margin clearance and recurrence was recorded and analysed. RESULTS: A total of 139 cases were recruited in this study. Four cases were lost in follow-up. Out of remaining 135 patients including 78 males and 57 females with a mean age of 58.6 years were studied. The commonest site of involvement was nose (45.9%), followed by periocular (28.1%) and cheek (15.6%) regions. The most common clinical type was nodular (51%) followed by ulcerative (38.5%). In majority of the cases, the resulting defect after excision was reconstructed with local flaps (57.8%). Majority (77.8%) of tumours had histopathologically clear margins while 20% had tumour involvement. During 2 years follow-up period, 8.9% patients had tumour recurrence.

Serum homocysteine as a risk factor for coronary heart disease.

BACKGROUND: Homocysteine (Hcy) is an intermediate formed during the catabolism of sulphur containing essential amino acid, methionine and Less than one percent of tHcy is found as the free form. Development of atherosclerotic changes and thrombo-embolism are common features in patients with homocysteinuria. This study was conducted to assess the relationship of Hcy and coronary heart disease (CHD) in our population. METHODS: The cross-sectional analytical study was carried out at the Department of Biochemistry, Hazara University Mansehra and Ayub Medical College, Abbottabad. A total of 80 subjects were included in this study and were divided into 2 groups. Cases Group consisted of 40 patients who had confirmed Myocardial Infarction (MI) coming for routine follow-up (first re-visit) after the acute attack. Control Group consisted of 40 matching healthy individuals. Demographic data including age, gender, dietary habits, height and weight as documented in preformed proforma. Blood pressure was taken in sitting posture. Serum total Hcy were measured. Data was entered into computer using SPSS 16.0 for analysis. RESULTS: The mean age of the cases was 59.68 +/- 8.06 (30-70) years and that of the controls was 58.93 +/- 6.93 (48-76) years. The average BMI of cases was 27.70 +/- 3.61 Kg/m2 and of the controls was 25.66 +/- 2.98 Kg/m2. This increase of BMI from controls to cases was statistically significant (p < 0.050). The mean systolic BP of the cases was 153.88 +/- 11.90 mmHg in comparison with 142.62 +/- 11.65 mmHg for the controls. This difference was statistically significant (p < 0.001). Mean tHcy level of the cases was 17.15 +/- 4.45 micromol/l while that of controls was 12.20 +/- 2.53 micromol/l. There is a statistically significant difference between cases and controls with respect to Hcy levels (p < 0.001). CONCLUSION: Plasma tHcy level has a powerful predictor value of CHD and routine screening for elevated Hcy concentrations is advisable especially for individuals who manifest atherothrombotic disease without their traditional risk factors.
