Comparison of Pedicle Coagulation Hemorrhoidectomy With LigaSure Versus Conventional Milligan Morgan Hemorrhoidectomy in Reducing Post-operative Pain: A Randomized Controlled Trial.

Background Hemorrhoids refer to the abnormal enlargement of the anal cushions. They are a common anorectal problem with a prevalence of 5% in the general population aged greater than 40 years. The objective of this study was to compare Milligan-Morgan open hemorrhoidectomy with pedicle ligation with LigaSure (Medtronic, Dublin, Ireland) in terms of postoperative pain on day 1 and day 7. It is important to assess the technique that is associated with lower postoperative pain because both of these techniques are still practiced in the developing world. Methods It was a randomized controlled trial conducted in the Department of Surgery, Rawalpindi, Pakistan. A total of 100 patients were selected and were allotted into the two groups by lottery method. Patients aged from 15 to 60 years who presented with symptomatic third and fourth-degree hemorrhoids were included after taking informed consent. Patients who had a previous or concomitant anorectal disease, patients who had undergone previous surgery for hemorrhoids, and those who were anesthetically unfit for surgery (American Society of Anesthesiologists (ASA) class 3 or above) were excluded from the study. Pain was assessed using the Visual Analogue scale (VAS). Data was entered and analyzed using SPSS v. 23.0 (IBM Corp., Armonk, USA). Chi-square tests were applied. P-value <0.05 was taken as statistically significant. Results Out of 100 patients, 68 (68%) were males while 32 (32%) were females. The mean age was 40.56±9.24 years. Postoperative pain at day 1 was 9.24±0.51 in the Milligan-Morgan group while that in the LigaSure group was 8.44±0.64 (p<0.0001). Postoperative pain at day 7 was 5.00±0.85 in the Milligan-Morgan group while it was 3.04±1.08 in the LigaSure group (p<0.0001). Conclusion LigaSure is a newer technique that helps to reduce complications as compared to other traditional hemorrhoidectomy procedures. Many patients avoid hemorrhoidectomy as it is associated with painful postoperative recovery. Pedicle coagulation with LigaSure was better than conventional Milligan-Morgan hemorrhoidectomy in terms of reducing the mean postoperative pain on 1st day and 7th day. Reducing the postoperative pain helps in greater patient satisfaction and lesser requirement of analgesia among patients of 3rd and 4th-degree hemorrhoids undergoing hemorrhoidectomy.

Rare case of mixed epithelial and stromal tumor (MEST) of the kidney and its diagnostic and therapeutic approach: A case report.

INTRODUCTION AND IMPORTANCE: Mix epithelial and stromal tumor (MEST) is a benign biphasic renal lesion composed of solid as well as cystic components lining tubular and cystic spaces of kidney. There are very few cases of such variety have been reported with perspective to renal involvement. Herein we have reported a rare case of MEST involving left renal tissue and sparing surrounding tissues. CASE PRESENTATION: A 20 years old female presented to surgical outpatient department with complaint of amenorrhea and left flank pain as well as heaviness for 1 year. Patient was vitally stable and cooperative. On physical examination left flank mass was palpated and ultrasound and CT scan imaging was also showing left renal mass confined to upper, middle and lower portion of the kidney while renal capsule, adrenal gland and ureter were spared. On histological examination showed multi-cystic structures with variably sized simple cysts lined by hobnailed epithelium with clear cells. Septa show ovarian type fibrous stroma with variable inflammation and immature nephrogenic elements. A final diagnosis of MEST was made. Therefore, radical nephrectomy with trans-peritoneal approach was done. CLINICAL DISCUSSION: MEST is a benign tumor of renal tissue that is confined to the renal parenchyma rather than involvement of surrounding structures as occurred in our case. Due to benign nature of the disease involvement of renal capsule and adrenal gland is less likely. The choice of treatment is radical nephrectomy through transperitoneal approach. CONCLUSION: MEST is a rare diagnosis thought case now start reporting since last decade, however, it's still a rare entity to be reported. USG and CT scan are investigating modalities along with histopathological correlation to reach the diagnosis.

Mycobacterium tuberculosis H37Rv: In Silico Drug Targets Identification by Metabolic Pathways Analysis.

Mycobacterium tuberculosis (Mtb) is a pathogenic bacteria species in the genus Mycobacterium and the causative agent of most cases of tuberculosis. Tuberculosis (TB) is the leading cause of death in the world from a bacterial infectious disease. This antibiotic resistance strain lead to development of the new antibiotics or drug molecules which can kill or suppress the growth of Mycobacterium tuberculosis. We have performed an in silico comparative analysis of metabolic pathways of the host Homo sapiens and the pathogen Mycobacterium tuberculosis (H37Rv). Novel efforts in developing drugs that target the intracellular metabolism of M. tuberculosis often focus on metabolic pathways that are specific to M. tuberculosis. We have identified five unique pathways for Mycobacterium tuberculosis having a number of 60 enzymes, which are nonhomologous to Homo sapiens protein sequences, and among them there were 55 enzymes, which are nonhomologous to Homo sapiens protein sequences. These enzymes were also found to be essential for survival of the Mycobacterium tuberculosis according to the DEG database. Further, the functional analysis using Uniprot showed involvement of all the unique enzymes in the different cellular components.

Association between time to clinical stability and outcomes after discharge in hospitalized patients with community-acquired pneumonia.

BACKGROUND: Adverse outcomes after discharge in patients hospitalized for community-acquired pneumonia (CAP) might be associated with the inflammatory response during hospitalization, recognized by the length of time needed for the patient to reach clinical stability (time to clinical stability [TCS]). The objective of this study was to assess the association between TCS and outcomes after discharge in hospitalized patients with CAP. METHODS: A retrospective cohort study of consecutive patients discharged alive after an episode of CAP was conducted at the Veterans Hospital of Louisville, Kentucky, between 2001 and 2006. RESULTS: Among the 464 patients enrolled in the study, 82 (18%) experienced an adverse outcome within 30 days after discharge, leading to either readmission or death. Patients with a TCS > 3 days showed a significantly higher rate of adverse outcomes after discharge compared with those with a TCS ≤ 3 days (26% vs 15%, respectively; OR, 1.98; 95% CI, 1.19-3.3; P = .008) as well as adverse outcomes after discharge related to pneumonia (16% vs 4.6%, respectively; OR, 4.07; 95% CI, 2-8.2; P < .001). The propensity-adjusted analysis showed that delay in reaching TCS during hospitalization was associated with a significant increased risk of adverse outcomes. Adjusted ORs comparing patients who reached TCS at days 2, 3, 4, and 5 to those who reached TCS at day 1 were 1.06, 1.54, 2.40, and 10.53, respectively. CONCLUSIONS: Patients with CAP who experienced a delay in reaching clinical stability during hospitalization are at high risk of adverse outcomes after discharge and should receive close observation and an early follow-up.

Acute myocardial infarction in hospitalized patients with community-acquired pneumonia.

BACKGROUND: An epidemiological link between respiratory infection and acute myocardial infarction (AMI) has been suggested, and recent data indicate that there is an association between AMI and pneumococcal community-acquired pneumonia (CAP) in hospitalized patients. The objective of this study was to investigate the association of AMI with the severity of pneumonia at hospitalization and clinical failure during hospitalization among patients with CAP. METHODS: An observational, retrospective study involving consecutive patients hospitalized with CAP was performed at the Veterans Hospital of Louisville, Kentucky. Patients admitted to the intensive care unit were defined as having severe CAP. Clinical failure was defined as the development of respiratory failure or shock. AMI was diagnosed on the basis of abnormal troponin levels and electrocardiogram findings. Propensity-adjusted models that controlled for clinical and nonclinical factors were used to investigate the association between AMI and pneumonia severity index and between AMI and clinical failure. RESULTS: Data for a total of 500 patients were studied. At hospital admission, AMI was present in 13 (15%) of 86 patients with severe CAP. During hospitalization, AMI was present in 13 (20%) of 65 patients who experienced clinical failure. Following risk adjustment, significant associations were discovered between AMI and the pneumonia severity index score (modeled with a restricted cubic spline) (P = .05) and between AMI and clinical failure (P = .04). CONCLUSIONS: A combined diagnosis of CAP and AMI is common among hospitalized patients with severe CAP. In cases in which the clinical course of a hospitalized patient with CAP is complicated by clinical failure, AMI should be considered as a possible etiology.

Incidence, etiology, timing, and risk factors for clinical failure in hospitalized patients with community-acquired pneumonia.

BACKGROUND: The etiology of clinical failure in hospitalized patients with community-acquired pneumonia (CAP) may be related or unrelated to pulmonary infection. The objective of this study was to define the incidence, etiology, timing, and risk factors associated with clinical failures related to CAP vs those unrelated to CAP. METHODS: Observational retrospective study of consecutive CAP patients. All patients who experienced clinical failure were identified. Cases were presented to a review committee that defined, by consensus, etiology, timing, and risk factors for clinical failures related to CAP. RESULTS: Among 500 patients who were enrolled in the study, clinical failure was identified in 67 (13%). Clinical failure was related to CAP in 54 patients (81%). The most common etiologies for clinical failure related to CAP were severe sepsis (33%), acute myocardial infarction (28%), and progressive pneumonia (19%). All cases of severe sepsis occurred in the first 72 h of hospitalization. The most common etiology for clinical failure unrelated to CAP was the development of hospital-acquired pneumonia (45%). At the time of hospital admission, factors associated with clinical failure related to CAP were advanced age, congestive heart failure, hypotension, abnormal gas exchange, acidosis, hypothermia, thrombocytopenia, and pleural effusion. CONCLUSIONS: The development of severe sepsis early during hospitalization is the primary etiology for clinical failure related to CAP. To achieve early treatment intervention, physicians should maintain a high index of suspicion for severe sepsis in hospitalized patients with CAP. To decrease the number of clinical failures unrelated to CAP, interventions need to be developed at the local level to improve the processes of care for patients with pneumonia.
