Distal pancreatectomy outcomes: Perspectives from a community-based teaching institution.

BACKGROUNDS/AIMS: Distal pancreatic resections are intricate operations with potential for significant morbidity; there is controversy surrounding the appropriate setting regarding surgeon/hospital volume. We report our distal pancreatectomy experience from a community-based teaching hospital. METHODS: This study includes all patients who underwent laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP) for benign and malignant lesions between June 2004 and October 2017. Both groups were compared for perioperative characteristics, parenchymal resection technique, and outcomes. RESULTS: 138 patients underwent distal pancreatectomy during this time. The distribution of LDP and ODP was 68 and 70 respectively. Operative time (146 vs. 174 min), blood loss (139 vs. 395 ml) and mean length of stay (4.8 vs. 8.0 days) were significantly lower in the laparoscopic group. The 30-day Clavien Grade 2/3 morbidity rate was 13.7% (19/138) and the incidence of Grade B/C pancreatic fistula was 6.5% (9/138), with no difference between ODP and LDP. 30-day mortality was 0.7% (1/138). 61/138 resections had a malignancy on final pathology. ODP mean tumor diameter was greater (6.4 cm vs. 2.9 cm), but there was no significant difference in the mean number of harvested nodes (8.6 vs. 7.4). The cost of hospitalization, including readmissions and surgery was significantly lower for LDP ($7558 vs. $11610). CONCLUSIONS: This series of distal pancreatectomies indicates a shorter hospital stay, less operative blood loss and reduced cost in the LDP group, and comparable morbidity and oncologic outcomes between LDP and ODP. It highlights the feasibility and safety of these complex surgeries in a community setting.

The enigma of granulomatous mastitis: A series.

Granulomatous mastitis is a chronic inflammatory breast disease with an enigmatic clinical presentation that can delay diagnosis and perpetuate ineffective treatments. We report our experience with the diagnosis and management of eighteen cases of granulomatous mastitis in the setting of an urban public hospital. The patients were identified after a retrospective review of pathology and surgery databases. Demographic, clinical, radiographic, histopathological data and treatment responses were reviewed. Out of a total of 18 patients, 8 patients were noted to be from Mexico. The mean age at presentation was 35 years and 11 of the 18 patients reported a pregnancy in the last four years. Most cases were unsuccessfully managed as bacterial breast infections initially; definitive treatment involved surgical excision and steroids. A complete symptomatic and radiographic resolution was documented in 8 of the 18 patients. Despite posing a challenge for the unsuspecting physician, an early diagnosis of granulomatous mastitis improves patient outcomes.

Hidden Obligatory Fluid Intake in Critical Care Patients.

INTRODUCTION: In addition to the fluid intake in the form of intravenous maintenance or boluses in intensive care unit (ICU) patients, there are sources of fluids that may remain unrecognized but contribute significantly to the overall fluid balance. We hypothesized that fluids not ordered as boluses or maintenance infusions-"hidden obligatory fluids"-may contribute more than a liter to the fluid intake of a patient during any random 24 hours of critical care admission. METHODS: Patients admitted to the Harlem Hospital ICU for at least 24 hours were included in this study (N = 98). Medical records and nursing charts were reviewed to determine the sources and volumes of various fluids for the study patients. RESULTS: The mean hidden obligatory volume for an ICU patient was calculated to be 978 mL (standard deviation [SD]: 904, median: 645) and 1571 mL (SD: 1023, median: 1505), with enteral feeds compared to the discretionary volume of 2821 mL (SD: 2367, median: 2595); this obligatory fluid volume was affected by a patient's need for pressor support and renal replacement therapy. CONCLUSION: Hidden obligatory fluids constitute a major source of the fluid intake among patients in a critical care unit. Up to 1.5 L should be taken into account during daily decision making to effectively regulate their volumes.

Enduring improvement in Oswestry Disability Index outcomes following lumbar microscopic interlaminar decompression: An appraisal of prospectively collected patient outcomes.

OBJECTIVES: Our present study aims to assess the short and long-term postoperative outcome of microscopic interlaminar decompression from a neurosurgical center in a developing country and also aims to further determine any predictors of functional outcome. MATERIALS AND METHODS: All patients with moderate to severe symptomatic stenosis undergoing elective posterior lumbar spinal decompression were prospectively enrolled in a database. Preoperative, 2 weeks and 2 years postoperative Oswestry Disability Index (ODI) scores were determined for all patients. These scores were retrospectively compared using repeated measures analysis of variance. Further, linear regression modelling was applied to determine the effect of preoperative ODI, body mass index, age, prior physiotherapy, duration of symptoms, and single or multiple level decompression on the change in ODI at 2 weeks and 2 years follow-up respectively. RESULTS: A total of 60 consecutive patients (40 males, 20 females) were included for statistical analysis. The percentage of patients with a minimum clinically important difference (MCID), using an ODI threshold value of 10, was 86.7% (n = 52) at the 2 weeks postoperative follow-up. At the 2 years follow-up assessment, 3.3% (n = 2) patients who had earlier not achieved MCID did so, 78.3% (n = 47) of patients were found to have a change in ODI score of <10 or no change, while 18.3% (n = 11) reported a deterioration in their ODI scores. The preoperative ODI score was an independent predictor of change in ODI score at 2 weeks and 2 years respectively (P < 0.0005). The duration of symptoms prior to surgery was found to predict the change in ODI at 2 years follow-up (P = 0.04). CONCLUSION: The evidence regarding the long-term and short-term efficacy of microscopic interlaminar decompression in symptomatic lumbar stenosis is overwhelming. Preoperative ODI scores and duration of symptoms prior to surgery can predict postoperative outcomes.

Craniocerebral injuries in war against terrorism --- a contemporary series from Pakistan.

OBJECTIVE: Terrorism-related bomb attacks on civilian population have increased dramatically over the last decade. Craniocerebral injuries secondary to improvised explosive devices have not been widely reported in the context of unarmored civilians. This series intends to report the spectrum of these injuries secondary to suicidal and implanted bombs as encountered at the Aga Khan University Hospital, Pakistan (AKUH). Further, a few pertinent management guidelines have also been discussed. METHODS: The hospital database and clinical coding during a 5-year period were examined for head injuries secondary to terrorism-associated blasts. In addition to patient demographics, data analysis for our series included initial Glasgow Coma Scale, presenting neurological complaints, associated non-neurological injuries, management (conservative or operative) to associated complications, and discharge neurological status. RESULTS: A total of 16 patients were included in this series. Among them 9 were victims of suicidal blasts while 7 were exposed to implanted devices. The patients presented with diverse patterns of injury secondary to a variety of shrapnel. A follow-up record was available for 12 of the 16 patients (mean follow-up: 7.8 months), with most patients having no active complaints. CONCLUSION: The results of this series show that civilian victims of suicidal and improvised bombings present with a wide range of neurological symptoms and injury patterns, which often differ from the neurological injuries incurred by military personnel in similar situations, and thereby often require individualized care.

Cerebrospinal fluid rhinorrhea: An institutional perspective from Pakistan.

BACKGROUND: The management of cerebrospinal fluid (CSF) rhinorrhea has evolved over the last two decades. We present here a review of our 11-year data on CSF rhinorrhea and its management at a tertiary care hospital in a developing country, with particular reference to the diagnosis, surgical management and outcome of the disease. METHODS: The medical charts of all patients with a diagnosis of CSF rhinorrhea over an 11-year period were reviewed. The etiology of CSF rhinorrhea was classified into three categories: spontaneous, iatrogenic and traumatic. All the patients were divided into three categories based on the type of management as conservative, intracranial and transnasal endoscopic groups. RESULTS: A total of 43 patients fulfilled our inclusion criteria and were included in the final analysis. Eleven of the 43 patients were managed conservatively, while 22 underwent intracranial repairs; 10 patients had transnasal endoscopic repairs. The primary success rate for the transnasal approach was 70% compared to 86% for the intracranial repair. Blood loss, special care unit (SCU) stay and total cost were found to be significantly less in the transnasal endoscopic group. Computed tomography (CT) cisternography was found to have the highest sensitivity and specificity. Further, no postoperative complications were found in the transnasal endoscopic group, while five patients from the intracranial group developed various complications. CONCLUSIONS: We conclude that the transnasal endoscopic approach has comparable success rates with the intracranial approach and significantly lower morbidity.

Critical appraisal of apparently evidence-based written advertising in Pakistan.

OBJECTIVES: The objective of the study was to critically assess references cited in support of claims in drug advertisements. METHODS: Drug advertising brochures were collected from privately practicing General Practitioners from different parts of Karachi. Three blinded reviewers then categorized each reference in the brochure according to the sources viz: journals (both Medline indexed and non-indexed), medical reference books, web addresses, personal communications or testimonials, abstracts presented at symposia/conferences, WHO and National Health Guidelines, 'data on file' and 'others' (which included a diverse set of references). Each reviewer then assessed and analyzed the references further into 2 broad categories: traceable and non-traceable. Traceable references were appraised and, depending upon the claim with which the reference was attached, were classified into justifiable, inaccurate/false, exaggerated and ambiguous. RESULTS: We collected a total of 175 different brochures. Thirty-nine (22.3%) brochures did not cite any references and were not subjected to further analysis. The remaining 136 (77.7%) contained a total of 559 references. 305 (54.6%) of these references were from Medline-indexed journals; 67 (12.0%) were from non-indexed journals; 55 (9.8%) references quoted medical reference books; 27 (4.8%) references cited web addresses; 12 (2.1%) references were personal communications/testimonials; 11 (2.0%) references referred to abstracts presented at symposia/conferences; 12 (2.1%) references were from WHO and National Health Guidelines; 8 (1.4%) references were listed as 'data on file', while the remainder that could not be defined were classified as 'others' (13.1%). Out of a total of 559 references, 249 (44.5%) could not be traced. After critically analyzing the 310 traceable references, 197 (63.5%) were adjudged justifiable, 30 (9.7%) inaccurate/false, 79 (25.5%) exaggerated and 15 (4.8%) ambiguous. CONCLUSION: Results of this study show for the first time that the claims substantiated with references in the pharmaceutical advertisements in Pakistan are highly unreliable.
