RESUMEN
Osteoarthritis of the knee is a prevalent condition that causes pain, discomfort, and disability that can severely impact the quality of life. This literature review aims to review the various interventional pain management techniques available to treat knee osteoarthritis. It analyzes the efficacy of various interventions such as intra-articular corticosteroids, prolotherapy, viscosupplementation, platelet-rich plasma, and genicular nerve blocks with radiofrequency ablation or cryoneurolysis. We searched databases for studies published in the past 20 years. A total of 37 articles were included. The literature supports the idea that a comprehensive treatment plan consisting of the various aforementioned techniques can provide relief for patients while delaying or avoiding joint replacement surgery.
RESUMEN
Lumbar spinal stenosis (LSS) occurs due to the narrowing of the space within the vertebral canal and or intervertebral foramina. This results in the compression of the spinal cord and possibly the roots of the spinal nerves. Lower back pain and neurogenic claudication (NC) are major symptoms of spinal stenosis. This is a literature review that summarizes the important findings pertaining to pain management of spinal stenosis. Twenty-four original articles were assessed. Pain can be treated through non-invasive or surgical methods. Conservative techniques include physical exercises, epidural corticosteroid injection, local anesthetic injection therapy, and oral analgesics. Surgical intervention deals with the decompression of the affected spinal region, with or without vertebral fusion surgery. Other novel surgical techniques include implantation of specific equipment, known as interspinous spacer devices and minimally invasive lumbar decompression (MILD). Most studies offering a comparative analysis have demonstrated that surgical intervention is more efficacious than non-surgical interventions to manage pain associated with spinal stenosis.
RESUMEN
Parsonage-Turner syndrome (PTS) is a rare neurological condition characterized by acute shoulder pain and novel neuromuscular weakness in the distribution of the brachial plexus. We present a case report highlighting the difficulties in the diagnosis and management of this condition. A multidisciplinary approach is often required to control this unique type of pain, consisting of neuropathic medications, non-steroidal anti-inflammatory drugs (NSAIDs) to control neuromuscular pain, and modalities provided by experienced physical therapists. Finally, a comprehensive, structured rehabilitation program focusing on the range of motion, neuromuscular re-education, and strengthening is imperative to regain function, reduce symptoms, and improve recovery.
RESUMEN
Femoral nerve palsy is a rare, but significant complication following percutaneous coronary intervention (PCI) for conditions such as myocardial infarction. We present a case of a 61-year-old male patient who presented for cardiac rehabilitation following an emergent PCI procedure for cardiac arrest secondary to ST-elevation myocardial infarction. He later developed right lower extremity weakness and severe neuropathic pain on arrival to the acute rehabilitation unit. After physical examination and electrodiagnostic studies, he was determined to have a right femoral nerve neuropathy. This case report highlights the clinical course, physical examination/electrodiagnostic findings, and subsequent pain management of femoral nerve palsies.
RESUMEN
In patients with a contraindication to oral anticoagulation, the left atrial appendage occlusion devices are an approved alternative. Device-related thrombus is a recognized complication, but underlying mechanisms are incompletely understood. In this case series, the authors describe potentially the same mechanism of thrombosis with intraoperative images of incomplete endothelialization. (Level of Difficulty: Intermediate.).
RESUMEN
INTRODUCTION: Sinonasal malignancies (SNMs) are a rare and heterogeneous group of cancers with an incidence of 3%-5% of all head-and-neck tumours. The aim of the present study was to identify the characteristic features of SNMs and to analyze the treatment outcomes and the prognostic factors affecting it. MATERIALS AND METHODS: A retrospective review of patients with SNM treated at a dedicated cancer center of Pakistan between 2004 and 2018 was carried out. All patients with histologically proven diagnosis of malignancy arising from nasal cavity or paranasal sinuses and being treated with curative intent were included. The medical records of 184 cases were utilized for final analysis. Chi-square test was applied to identify significant differences. Five-year disease-specific survival (DSS) was calculated using Kaplan-Meier curve via log-rank test and comparison was made between squamous and nonsquamous histologies. P ≤0.05 was considered statistically significant. RESULTS: Squamous cell carcinoma was the most common histopathology (n = 62, 33.7%). 130 (70.7%) patients presented with stage IV disease. Nodal metastasis was seen in 24 (13%) patients. Treatment failure was seen in 96 (52.2%) patients and was significantly associated with tumour size and the overall stage. DSS of patients with squamous cell carcinoma was 29% as compared to 52% for patients with nonsquamous histologies (P = 0.001). DISCUSSION: SNM is a diverse group of cancers presenting in late stages. A higher rate of treatment failure associated significantly with stage of the disease was identified in our study.
RESUMEN
Leclercia adecarboxylata is a motile, gram negative bacillus in the Enterobacteriaceae family that is a rarely isolated cause of disease, despite being ubiquitous in nature. A 2019 review article identified only 74 reported cases, most often in immunocompromised patients [1]. The organism is generally susceptible to most antibiotics although multiantibiotic resistant strains have been reported. We report a case of a 62-year-old Caucasian man with multiple co-morbidities treated for L. adecarboxylata endocarditis with intravenous ceftriaxone.
RESUMEN
OBJECTIVES: To analyze the factors predicting survival outcomes in treatment naïve oral tongue squamous cell carcinoma (OTSCC). MATERIALS AND METHODS: A comprehensive review of 531 oral tongue carcinoma patients treated with upfront surgery followed by adjuvant radiotherapy or chemoradiotherapy was conducted from 2004-2018. RESULTS: The mean age of presentation was 53 years (11-86) with a male to female ratio of 1.3:1. The associated risk factors were smoking (21%), betel nut (16%), naswar (9%) and alcohol (1%). Most of the cases were either well (45.1%) or moderately (46.2%) differentiated. Surgery was performed in 164 patients alone while 368 were treated with surgery in combination with adjuvant modalities. Overall (OS) and disease free survival (DFS) were 66 and 71%, respectively, with a median follow up of 2.5 years. Cox regression analysis showed nodal positivity, increased depth of invasion (DOI) and higher lymph node ratio (LNR) as significant prognosticators impacting OS and DSS. CONCLUSION: Nodal volume, DOI and LNR are the most consistent predictors of poor outcome in OTSCC. Nodal positivity, depth of invasion > 5 mm and lymph node ratio > 0.04 adversely affect OS and DSS.

The objective of this study was to ascertain the safety and efficacy of sofosbuvir in patients undergoing hemodialysis. Twenty-three HCV infected patients undergoing hemodialysis were included. Sofosbuvir was administered in combinations with ribavirin, daclatasvir and ledipasvir for 12-24 weeks. Viral response was checked at the end and 12 weeks after completing therapy. Twenty-one (91.3%) were of genotype 3 and two (8.7%) genotype 1. Eight (34.8%) had cirrhosis. Three (13%) were previous relapsers to sofosbuvir and ribavirin, while one (4.3%) was relapser to interferon. Sofosbuvir plus ribavirin was given to four (17.4%), sofosbuvir plus daclatasvir to eleven (47.8%), sofosbuvir plus daclatasvir plus ribavirin to four (17.4%), sofosbuvir plus velpatasvir to three (13%), and sofosbuvir plus ledipasvir to one (4.3%) patient. Twenty-one (91.3%) achieved viral eradication on completion of treatment; two were non-responders. Nineteen (82.6%) had undetectable virus 12 weeks after ending treatment and remaining two (8.7%) relapsed. Adverse effects were not observed. Hence, sofosbuvir can be safely used in patients undergoing hemodialysis. Key Words: Sofosbuvir, Hemodialysis, Hepatitis C.

Background: Incidence of thyroid gland invasion in advanced laryngeal cancers is low. Ipsilateral or total thyroidectomy along with total laryngectomy has been controversial and there has been no consensus over the management of thyroid gland in advanced laryngeal cancers.Objective: To determine the frequency of thyroid gland invasion in locally advanced laryngeal squamous cell carcinoma and the risk factors associated with it.Material and methods: A retrospective review of patients with laryngeal squamous cell carcinoma operated at our center between January 2011 and December 2018 was carried out. Patients undergoing upfront or salvage laryngectomy with or without neck dissection along with hemi or total thyroidectomy were included. Histopathology reports were reviewed to record the involvement of thyroid gland.Results: Invasion of thyroid gland by squamous cell carcinoma larynx was seen in 10 (10.9%) patients out of 92. All of the cases showed direct extension of the tumor. Trans-glottic, subglottic, and tumors with extra laryngeal spread were found to be significantly associated with thyroid gland invasion. Patients with thyroid gland invasion showed higher rate recurrence.Conclusion and significance: Incidence of thyroid gland invasion in squamous cell carcinoma larynx is low, allowing us not to address thyroid routinely in patients undergoing total laryngectomy for laryngeal carcinoma.

BACKGROUND: The new AJCC staging system (8th edition) incorporates depth of invasion to stage oral cancers. It is a recognized predictor for neck nodal metastasis and local recurrence, the associated risk is not well defined. The aim of this study was to explore the risk of occult neck nodal metastasis and local recurrence in relation to depth in early stage squamous cell carcinoma of oral tongue. METHODS: We have evaluated records of 179 patients with early tongue cancer treated in our unit from 2006-2015 with a mean age of 57.92 ± 11.93 years. Treatment modalities used were surgery (26%), surgery followed by radiotherapy (64%) and chemo-radiation (10%). Neck dissection was ipsilateral in 94% and bilateral in 6% of the patients. Patients were grouped according to the AJCC cut off points in 8th edition for depth; group A: 1-5 mm (35%), group B: 6-10 mm (47%) and group C: > 10 mm (18%). RESULTS: Risk of local recurrence and nodal metastasis for Group A was 15% (10/63) and 23% (15/63), group B 20% (17/84) and 34% (29/84), and group C 40% (13/32) and 53% (17/32). CONCLUSIONS: Depth more than 10 mm is associated with significantly increased risk of recurrence and nodal metastasis. Elective neck dissection should be a consideration for tumors having depth less than 5mm.

Introduction Development of laryngeal cancer is multifactorial, and management is surrounded with controversies. Recent reports suggest a decline in the survival of these patients. We conducted a study to analyze the clinicopathological parameters and compute the outcomes in terms of survival in patients with laryngeal cancer treated at our institution. Methods Electronic charts of 515 patients with Laryngeal cancer treated at our Hospital and Research Center from 2004 to 2014 were retrospectively reviewed. Results Median age was 62 years. Male: female ratio 91%: 9%. Sixty-two percent were smokers. Histologically, all were squamous cell carcinoma. Most common subsite was glottis (88%). Treatment was non-surgical in 92% and surgical in 8%. The five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS) and locoregional control (LRC) were 67%, 74%, 59% and 70%, respectively. OS, DSS, DFS and LRC for early stage (I-II) and advance stage (III-IV) were 81 and 54%, 86 and 63%, 75 and 45%, and 83 and 57%, respectively. Twenty-two percent recurred locally. Of these failures, 19% were inoperable, 36% were surgically salvaged and 34% refused laryngectomy. Conclusions Our survival rates are comparable with published data. The high refusal rate for salvage total laryngectomy is concerning and needs further study to evaluate the reasons.
RESUMEN
OBJECTIVE: To evaluate the therapeutic efficacy of endoscopic dilatation of anastomotic stricture (AS). STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Department of Gastroenterology and Hepatology, Shaikh Zayed Hospital, Lahore, Pakistan from November 2016 to November 2017. METHODOLOGY: Patients presenting with anastomotic biliary stricture following living donor liver transplant (LDLT) underwent endoscopic retrograde cholangio-pancreaticography (ERCP) and treatment of their strictures with dilatation with or without stenting. The patients were then followed up to see adequate resolution of stricture and repeat therapeutic ERCP was performed, if required. The patients were labelled as cured if stricture resolution persisted for a period of up to six months following ERCP. RESULTS: Forty-three patients (32 males and 11 females), with post-LDLT AS, who met the inclusion and exclusion criteria were enrolled in the study. Thirty-six (83.7%) patients had a single biliary anastomosis while seven (16.3%) patients had two anastomoses. Ductoplasty was done in 15 (34.9%) of the enrolled patients. Patients with post-LDLT AS required 3.65 +1.15 sessions of ERCP. Plastic type biliary stent was used in seven (16.3%) patients, balloon dilatation alone was done in five (11.6%) patients and combined balloon dilatation and stent placement was performed in 29 (67.4%) patients, and combined graduated dilator and stent placement was performed in two (4.7%) patients. Five (11.6%) patients required rendezvous procedure (whereby a radiologist placed a guidewire percutaneously into the biliary system) as guidewire placement across stricture site was endoscopically unsuccessful. The overall success rate was 88.4%. Mean stent free follow-up was 7.18 +1.38 months. Recurrence of AS was noted in one (2.3%) patient. CONCLUSION: Endoscopic management of post-LDLT AS has an efficacious long-term outcome.

Honey bees will learn to respond to an odor when their antennae are stimulated with sucrose, even if they are not fed during the conditioning phase. However, if they are not fed, the memory of this association is significantly reduced 24â¯h after conditioning. These results suggest that stimulation of proboscis with sucrose and/or the nutritional quality of the reward plays an important role in establishing a long lasting memory. Three sugars, xylose, sorbitol and mannitol, are used to investigate the relationship among learning, sensory perception and nutritional value. The proboscis extension reflex is used to show that honey bees cannot taste these sugars, whereas mortality data suggest that bees can metabolize all three sugars. Feeding with sorbitol or xylose during olfactory associative conditioning restores robust 24â¯h memories. However, when given a free choice between consuming sucrose alone or sucrose supplemented with these nutritional sugars, bees did not show a preference for food containing the higher nutritional content. Furthermore, bees did not ingest solutions containing only the tasteless sugar even when it was the only food source. Together, these results suggest that nutritional content and not just sensory information is important for establishing long term memories, but that bees may not be able to assess nutritional content when it is disassociated from taste.

Introduction The incidence of salivary gland tumors is influenced by geographical and racial factors resulting in diverse histology. While salivary gland tumors account for a low proportion of head and neck cancers, most malignant tumors of the salivary gland are located in the parotid gland. The goals of this study are to describe the clinicopathological behavior of malignant parotid tumors and explore oncological outcomes related to survival in our Pakistani tertiary care cancer hospital. Methods We conducted a retrospective analysis of 209 patients diagnosed with malignant parotid tumors from 2004 to 2016. Data such as demographics, age, gender, histology, grade, clinical and pathological stage, surgical treatment types and adjuvant modalities used were analyzed using SPSS software version 20. We used Kaplan Meier curves to analyze survival data. Results The median patient age at diagnosis was 40 years, and the ratio of men to women was 1.2:1. Mucoepidermoid carcinoma was the most common histological variant (with a 50% incidence rate) followed by adenoid cystic carcinoma (13%), and adenocarcinoma (10%). Histology has further categorized these malignant tumors into low (34%), intermediate (28%), and high (21% ) grades. The American Joint Committee on Cancer, seventh edition, clinical staging was Stage I (21%), II (28%), III (15%), and IV (34%). The 5-year survival was 68%, and the 10-year survival was 45%. Conclusion Mucoepidermoid carcinoma is the most common malignant parotid histology in our patient population. Advanced age, increased T stage (size > 4 cm), high-grade histology, and cervical nodal involvement decrease overall survival. Open biopsies, piecemeal excisions, and delayed presentation for radiotherapy post-surgery may also have role in adverse outcomes in these malignancies.
RESUMEN
BACKGROUND: Obstructive jaundice due to malignancies of the biliary tree, gall bladder and pancreas account for a significant number of patients managed by tertiary centres. Management options are curative or palliative, depending on disease stage. This study was performed to see the effectiveness of treatment modalities for these patients and eventual outcome. METHODS: This cross-sectional analytical study was conducted at the Department of Gastroenterology and Hepatology, Shaikh Zayed Hospital Lahore, from January 2015 to June 2016. All adult patients aged 18 and above of either sex presenting with obstructive jaundice secondary to malignant disease originating from the gallbladder, biliary-tree or pancreas were included in the study. The disease was staged after admission. The patients then underwent endoscopic, surgical or percutaneous drainage and were followed up for a period of one year. RESULTS: Two hundred & sixty-two patients presenting with jaundice due to malignancy arising from the biliary tree, gall bladder or pancreas were enrolled between January 2015 and June 2016, 141 (53.8%) males and 121 (46.2%) females. Eighty (30.5%) had cholangiocarcinoma, 70 (26.7%), had gall bladder tumours, 61 (23.3%) pancreatic cancer and 51(19.5%) had ampullary tumours. 31 (11.8%) patients had disease qualifying curative surgical resection. One hundred & eighty-five (70.6%) patients underwent palliative therapy in the form of percutaneous in 86 (32.9%) and endoscopic drainage in 126 (48.1%). Twenty-eight (10.7%) patients refused all treatment. Eighteen (6.9%) patients died before undergoing any therapeutic intervention. Thirty-three (12.6%) died during hospital stay. Survival at 3, 6 and 12 months was 49.2% (129 patients), 28.2% (74 patients) and 8.4% (22 patients), respectively. These 22 included all patients who had undergone curative resection. We attributed the largest number of deaths, 197 (75.2%) patients, to metastatic/advanced disease and associated complications. CONCLUSIONS: The results showed that patients with advanced disease who were only eligible for palliative therapy, at first presentation, constituted the majority of patients. These patients require skilled endoscopy and interventional radiology teams for successful biliary drainage.

BACKGROUND: Technological innovations based on light amplification created by stimulated emission of radiation (LASER) have been used extensively in the field of neurosurgery. METHODS: We reviewed the medical literature to identify current laser-based technological applications for surgical, diagnostic, and therapeutic uses in neurosurgery. RESULTS: Surgical applications of laser technology reported in the literature include percutaneous laser ablation of brain tissue, the use of surgical lasers in open and endoscopic cranial surgeries, laser-assisted microanastomosis, and photodynamic therapy for brain tumors. Laser systems are also used for intervertebral disk degeneration treatment, therapeutic applications of laser energy for transcranial laser therapy and nerve regeneration, and novel diagnostic laser-based technologies (e.g., laser scanning endomicroscopy and Raman spectroscopy) that are used for interrogation of pathological tissue. CONCLUSION: Despite controversy over the use of lasers for treatment, the surgical application of lasers for minimally invasive procedures shows promising results and merits further investigation. Laser-based microscopy imaging devices have been developed and miniaturized to be used intraoperatively for rapid pathological diagnosis. The multitude of ways that lasers are used in neurosurgery and in related neuroclinical situations is a testament to the technological advancements and practicality of laser science.
RESUMEN
INTRODUCTION: Ano-rectal abscesses are common. They however usually do not present with abdominal symptoms. CT although useful is not routinely carried out. Finding of Pneumo-retro-peritoneum with ischio-rectal abscess is rare. CASE PRESENTATION: We present the case of a diabetic gentleman who presented with abdominal pain and distension and was found to have ischio-rectal abscess on perianal examination. Although initially suspected to have acute abdomen due to perforated viscus, CT scan revealed pneumo-retro-peritoneum which appeared to arise due to the abscess. Patient underwent incision and drainage of the abscess followed by serial debridement. He made a complete recovery. CONCLUSION: Abdominal symptoms are rare in ischio-rectal abscess, but they must be kept in mind. Proper diagnosis may avoid a negative laparotomy.
