Analysis of Pyogenic Liver Abscesses

Published on: 19th January, 2018

OCLC Number/Unique Identifier: 7325071770

Background: Pyogenic liver abscesses (PLA) are frequent in immunosuppressed patients. We review the characteristics of patients with PLA at a tertiary academic Spanish hospital in Asturias. Methods: A retrospective observational study for 10 years, between 2006-2015. Epidemiological, clinical, analytical characteristics, treatment and hospital stay of the patients with PLA were analyzed. Results: 99 patients, 62 (62.6%) men, with age ≥65 years (72.7%). The most frequent etiology was: Biliary (40%), postsurgical (15%) and intestinal origin (11%). The most frequent clinical signs were fever, showing significant differences, abdominal pain (p=0.001) and nausea (p=0.02) between biliary PLA and the rest of the PLA. Microbiological results were confirmed in 63% (62 cases). All were treated with antibiotic therapy, along with percutaneous drainage (44.4% (44 cases)); and surgical drainage (12.1% (12 cases)). The overall mean stay was 23.1 days without significant differences between those treated with percutaneous drainage or surgical drainage. Conclusion: PLA predominate in patients ≥65 years. Biliary PLA are the most frequent, diagnosed at an older age than the intestinal PLA (p=0.005). - The treatment is based on systemic antibiotherapy and percutaneous drainage, especially in PLA only >5cm (p=0.019). - There are no significant differences in average stay of patients treated with percutaneous drainage or surgical drainage.

Clinical significance of Vibration Anesthesia on reducing pain of Ring-Block (Subcutaneous Injections) in the patients undergoing Hair Restoration Surgery

Published on: 18th October, 2017

OCLC Number/Unique Identifier: 7317634401

Pain is a complex phenomenon which is unpleasant. Different cosmetic procedures are associated with varying degrees of pain. Various modalities are adopted to decrease the severity of pain. The commonly used is the administration of analgesics (opioid or non-steroidal). The pain is carried to the brain by pain fibres. There are various theories about the pain [1,2]. Many attempts have been undertaken to find the modalities which decrease the perception of pain by the brain. The famous ‘gate theory’ was proposed in 1965 by Melzack et al. [3]. It was proposed that the pain experience can be reduced by the activation of nerve fibres that conduct non-toxic stimuli. The theory suggested that the stimulation of larger diameter fibres (A-beta) can close a neural ‘gate’ to nocioceptive signals and can reduce the perception of the pain. The ‘gate’ is proposed to lie within the spinal cord/brainstem and inhibits the transmission of nocioceptive action potentials to higher centres in the central nervous system [4]. The “post-synaptic inhibitory and fascilitatory mechanism” provide a basis for explaining the pain reducing strategies such as rubbing the painful area or applying cold or vibration to decrease the perception of the pain. Various topical irritants used in a few ‘magic’ creams also work on the same principle. Every effort is made to decrease the perception of pain in cosmetic surgery procedures especially hair restoration. A surgeon who can perform a hair restoration without pain has an edge over his competitors. The potential patients undergoing hair restoration are very anxious about the pain level to be perceived during the procedure. Vibration anaesthesia is becoming increasing used in hair restoration to decrease pain perception. Various recent studies have demonstrated the effective use if vibrations to decrease the pain of local anaesthesia injections [5,7]. The pain of the injection has basically two components; the first is the actual needle prick and second is the discomfort felt due to the tissue stretch by the local anaesthetic drugs [8]. The following study was conducted to compare the pain level of ring block in the patients undergoing hair restoration with and without the use of vibration

Hepatic adenomatosis: A clinically challenging rare liver disease

Published on: 11th July, 2018

OCLC Number/Unique Identifier: 7828397085

43-year-old lady presented with incidentally discovered liver lesions while she was being managed for her complaints of menorrhagia. CT and MRI showed hepatomegaly with multiple lesions in both lobes of the liver with vascular element in the background of diffuse fatty infiltration. Patient underwent laparoscopic core biopsy. Histopathology showed extensive steatosis, intracytoplasmic giant mitochondria and absence of portal tracts, features highly suggestive of hepatic adenomatosis. IHC staining showed membranous and cytoplasmic positivity in hepatocytes for B-catenin consistent with multiple hepatic adenomatosis. Hepatic adenomatosis is a new clinical entity in the hepatological practice characterized by the presence of 10 or more nodules in the liver known for its major complication of bleeding. Hepatic adenomatosis is managed by regular imaging and resection of large (> 5cm) superficial and painful adenomas along with liver function tests and tumor markers to rule out malignant transformation. However, the potential cure being the liver transplantation.

Laparoscopic partial nephrectomy-does tumor profile influence the operative performance?

Published on: 10th October, 2017

OCLC Number/Unique Identifier: 7317597242

Introduction: Laparoscopic approach is emerging as a standard of care approach for management of masses amenable to partial nephrectomy. Laparoscopic partial nephrectomy is a challenging surgery and its successful performance depends on various factors. We aim to evaluate the influence of tumor characterestics on the operative performance for laparoscopic partial nephrectomy. Methods: Patients undergoing laparoscopic partial nephrectomy in our institution were recruited for this study. The tumor profile was evaluated by a senior radiologist from cross sectional imaging (computed tomography or magnetic resonance imaging). Tumor characerestics was defined by assessing tumor size, tumor location and RENAL score. The operative performance was evaluated in terms of warm ischemia time, blood loss, operation duration and any significant operative complications. Statistical inference was drawn. Results: 37 patients who underwent laparoscopic partial nephrectomy between January 2010 and June 2012 were included in this study. The mean tumor dimension was 3.81 cms. 21 tumors involved left kidney and 16 involved right kidney. 12 were located in upper pole, 8 were located in midpole and 17 were located in lower pole. The average RENAL score was 6.56. The mean warm ischemia time, blood loss and operation duration was 26.29 minutes (min), 256.76 millilitres (ml) and 208.11 min respectively. Statistically significant correlation was appreciated between tumor location (polar location, side, anterior/ posterior location) and RENAL score and operative parameters (warm ischemia time and operation duration). Tumor size did not have any correlation with the operative parameters. Conclusion: The operative performance of laparoscopic partial nephrectomy is significantly influenced by the tumor location and RENAL score.

Scrotal Hydroceles not associated with Patent Processus Vaginalis in Children

Published on: 2nd May, 2018

OCLC Number/Unique Identifier: 7666304079

Background: After the closure of patent processus vaginalis (PPV) in boys with indirect inguinal hernia (IIH) or hydrocele, large scrotal hydroceles can occur on rare occasions despite the complete occlusion of internal inguinal ring (IIR). We present some cases that may help to explain the cause of this rare occurrence. Materials: During last 14 years, six boys exhibited non-communicating large scrotal hydroceles (2 right, 1 left, 3 bilateral) among 352 children who underwent laparoscopic repair for hydroceles. Ages ranged from 7 months to 15 years with a median of 12 years. Five of them had a history of repair for hydrocele or IIH prior to the definitive surgery and one boy underwent an initial operation. Results: In all the patients, laparoscopic inspection at the definitive surgery revealed completely closed IIRs. One infant with primary hydroceles was found to have large hydroceles bulging into the peritoneal cavity. All the patients were treated with subtotal removal of the sac without any recurrence. Marked thickness of the sack walls with abundant lymph vessels was characteristic histopathological findings. Conclusions: The complete occlusion of the PPV does not always prevent the recurrence of hydrocele through alternative pathogenesis. The pathological findings of resected specimens suggested a disturbance in lymph flow in the testicular system. The subtotal removal of the sac is the treatment of choice. Diagnostic laparoscopy prior to a direct cut-down approach to the neck of the seminal cord is advisable to identify non-communicating hydroceles to avoid further impairment of lymph drainage around the IIR.

Fallow Lands of Tuva (Russia): 30 years of Steppe Demutation

Published on: 27th October, 2023

Tuva has been a cattle-breeding region since ancient times, extremely continental climate of this region is little suitable for agriculture. However, the steppes of intermountain depressions in Tuva were heavily plowed by the early 1980s. In the 1990s most of the arable lands were abandoned; the process of restoration (demutation) of natural vegetation on fallow lands began. By now, 30 years later, the old fallows are expected to achieve the stage of the secondary steppe.The purpose of this work is to estimate the differences between virgin steppes and corresponding secondary steppes in Tuva. Tussock, hummock, and desert virgin steppes have been compared with corresponding to three types of 30-year-old fallow communities. For this study, 330 geobotanical releves have been used. The criteria for comparison have been chosen as follows: the similarity of species composition, the spectrum of dominant species, species richness, grass cover, and grass height. The statistical validity of their differences has been verified. According to these criteria, virgin steppes and their 30-year-old fallow derivatives are shown to differ significantly.

Impact of Diabetes on the Nutritional Status of CKD Patients

Published on: 9th January, 2017

OCLC Number/Unique Identifier: 7317654942

Background: Prevalence of malnutrition in Chronic Kidney Disease (CKD) patients is due to their lower appetite level. Diabetic patients experience polyphagia. Hence it is necessary to understand the impact of diabetes on the nutritional status of CKD patient. Aim: To compare the nutritious status between the CKD patients with and without diabetes. Objectives: To find out the impact of diabetes on the nutritional status of CKD patients. Method and Materials: A prospective random sampling method was adopted to select the subjects. Eighty CKD patients were divided equally into two groups. Tool which has been used to collect the data was SOAP format. Results: While comparing BMI between group 1(CKD without diabetes) and group 2(CKD with diabetes) it was noticed that the percentage of normal nourished subjects in group 2 were greater than that of group1. About 63% and 25% of subjects with CKD in group1 had normal BMI and grade 1 undernourished respectively. In group 2, about 75% and 10% of patients had normal BMI and grade 1 over nourished respectively. About 80% of subjects in group 2 were on insulin treatment. About 88% of subjects in group1 were anorexic and about 55% and 25% of subjects in group 2 had polyphagia and normal appetite respectively. The difference in the energy and protein intake between the two groups was statistically significant at p<0.01 level. Conclusions: It can be concluded from the above study that a better nutritional status was found in the CKD patients with Diabetes Mellitus (DM) than the CKD patients without DM which may be due to their normal appetite/ polyphagia, hence allowing a better food intake among group2 subjects. Weight gain in CKD with DM patients may be due to increase in fat mass which is subsequent to lipogenic effect of insulin.

Anterior Laparoscopic Approach Combined with Posterior Approach for Lumbosacral Neurolysis: A Case Report

Published on: 25th November, 2024

Background and importance: Sacral fractures often lead to injuries of the lumbosacral nerve, which will cause tremendous damage to the patient’s motor and sensory functions. At present, the most commonly used surgical method is the posterior median approach, the extent and degree of neurolysis are often insufficient, so the effect of neurolysis is not well, and the functional recovery of patients after operation is often incomplete.Clinical presentation: The patient was a 17-year-old male who accidentally fell from a height and landed on his hip. The main clinical feature of the patient was persistent radiating pain in the right lower extremity with right lower limb sensorimotor disorder. The results of the X-ray examination indicated a sacral fracture and a right pubic fracture. After the injury, the patient underwent pelvic internal fixation surgery within 72 hours. Then 6 months after the surgery, there was no significant improvement in right lower limb function, and the patient came to our hospital seeking treatment. Considering the severe lumbosacral plexus injury and the history of surgery, we performed an “Anterior surgery approach combined with posterior approach for lumbosacral neurolysis” for the patient, postoperative radiation pain disappeared completely, and there were significant improvements in the muscle strength of some muscles and sensory function.Conclusion: The relaxation of the lumbosacral plexus is usually performed through a single surgical approach, which has great limitations in the effect of relaxation. Here, we demonstrate a case in which posterior lumbar incision and anterior laparoscopic lumbosacral plexus neurolysis can benefit the patient, the lumbosacral nerve was released to a great extent. We aim to bring this case to the attention of our worldwide neurosurgical colleagues and share our surgical approach to assist those who may encounter this case in the future.
