Eight years experience of transanal endoscopic microsurgery

Introduction: Transanal Endoscopic Microsurgery (TEM) is a minimally invasive method for management of different proctologic conditions. Despite widespread use of this method, it is not used widely in Iran. This report is about to describe the application of TEM in managing different proctologic conditions in a tertiary colorectal referral center in Iran regarding methods and complications. Methods: All of the patients' documents such as procedure, method, early postop complications and further operations were actively reviewed and the data were entered in to the database. Results: Since 2012 till the end of 2020 chart review was done and 150 cases of TEM operation were found. The most frequent procedure that was done was resection procedure. Using different energy devices during surgery or suturing versus not suturing the defect were not associated with complication. There was a case of in hospital mortality and one case delayed perianal fistula following TEM. Measurement of lesion distance from anal verge was not significantly different using TEM or colonoscopy. Villous adenomas detected in colonoscopy were mostly associated with malignancy. In evaluated resected lesions most of cases had free base and distance from anal verge or using different energy devices were not associated with obtaining free base. Conclusion: TEM is a safe minimal invasive procedure with acceptable complications that could be helped in managing different proctologic conditions and the results of reviewing our patients revealed the same results that is reported from other colorectal centers.

Aqueous deficiency dry eye in post conjunctivitis cicatrization - Effect of deep thermal punctal cautery

Purpose: To evaluate the effect of deep thermal punctal cautery in eyes with post?conjunctivitis cicatrization. Methods: This retrospective study consisted of patients who underwent deep thermal punctal cautery for post?conjunctivitis dry eye (PCDE). The diagnosis was based on a history suggestive of viral conjunctivitis in past followed by the onset of present clinical features of aqueous deficiency dry eye (ATD). All patients underwent a rheumatological evaluation to rule out underlying systemic collagen vascular disease as a cause for dry eye. The extent of cicatricial changes was noted. Best?corrected visual acuity (BCVA), Schirmer’s test, and fluorescein staining score (FSS; total score of 9) were analyzed pre? and post?cautery. Results: Out of 65 patients (117 eyes), 42 were males. The mean age at presentation was 25.769 ± 12.03 years. Thirteen patients presented with unilateral dry eye. Pre?cautery BCVA (logarithm of the minimum angle of resolution [logMAR]) and Schirmer’s test (mm) improved from 0.5251 ± 0.662 to 0.372 ± 0.595 (P value = 0.000, 95% confidence interval [CI]: 0.09–0.22), and 1.952 ± 2.763 to 4.929 ± 4.338 (P value = 0.000, 95% CI: ?3.79–?2.17); post?cautery, respectively. The pre?cautery FSS of 5.9 ± 2.82 reduced to 1.58 ± 2.38 (P value = 0.000, 95% CI: 3.46–5.17) post?cautery. The mean follow?up was 11.22 ± 13.32 months. No progression in cicatricial changes was noted in any eye during the follow?up. Re?canalization rate was 10.64%, and repeat cautery was performed with successful closure of puncta. Conclusion: Symptoms and clinical signs of ATD in PCDE patients improve with punctal cautery

Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine / 中西医结合学报

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Comparison of Three Tonsillectomy Techniques: Cold Dissection, Monopolar Electrocautery, and Coblation

Abstract Introduction Tonsillectomy is among the most common otolaryngological surgeries. Objective To evaluate and compare three tonsillectomy techniques: cold steel dissection (CSD), monopolar electrocautery (MEC), and coblation. Methods The present study retrospectively reviewed the medical records of patients who underwent tonsillectomy between January 2014 and January 2016. Postoperative visual analog scale (VAS) pain scores, analgesic use, surgical duration, time to return to normal activity, and postoperative bleeding status were noted. Results The CSD group had less analgesic use and shorter return to normal activity than the MEC group (p =0.037 and p < 0.001, respectively). The coblation group had lower VAS pain scores than the MEC group only at 1 hour to 4 hours postsurgery (p <0.016). The postoperative bleeding rate was similar in all groups (p = 0.096). Conclusion Cold steel dissection tonsillectomy is associated with less postoperative pain and shorter recovery than MEC. Coblation is better than MEC in terms of postoperative pain at 1 hour to 4 hours only, whereas CSD is associated with less postoperative pain than coblation at 2 days to 7 days.

Evaluation of cautery in manual small-incision cataract surgery

Purpose: Manual small-incision cataract surgery (MSICS) has a major role in tackling cataract blindness in our country. Cauterization of sclera is one of the important steps performed in MSICS to have bloodless field during surgery. Only few studies have addressed the effect of cautery on post?operative astigmatism. The present study is designed to evaluate the effect of cautery on surgically induced astigmatism in Indian patients. Methods: The study was designed as a prospective randomized trial conducted in a tertiary health care institution over a period of 2 years. A total of 150 eyes were randomized into two groups. The study group (Group 1, n = 75) underwent MSICS with cauterization using wetfield bipolar cautery with 4 amperes power. In the control group (Group 2, n = 75), no cauterization was performed. Surgically induced astigmatism was calculated using Naesers polar value method and compared between these two groups up to 60 days post?operatively. Results: Data from 150 eyes were available for evaluation. The net post?operative astigmatic value was 1.01 � 0.21, 1.04 � 0.19, and 1.03 � 0.22 D on the 1st, 7th, and 30th post?operative days, respectively, showing a stable trend in patients undergoing cauterization. In Group 2, the net post?operative astigmatic values observed were 0.47 � 0.11 D, 0.54 � 0.10, and 0.54 � 0.09 D on the 1st, 7th, and 30th post-operative days, respectively. The mean value of surgically induced astigmatism at 2 months post?operatively with and without cautery was 0.60 � 0.20 D at 90� and 0.47 � 0.10 D at 90�. The difference was not statistically significant (P = 0.08). Conclusion: The results of this study show that the use of cautery in MSICS is not associated with a higher surgically induced post?operative astigmatism. The magnitude of surgically induced astigmatism decreases with time.

Consenso de epistaxis en pediatría: causas, clínica y tratamiento / Consensus on pediatrics epistaxis: Causes, clinic and treatment

Se define la epistaxis como el sangrado proveniente del vestíbulo, la cavidad nasal o la nasofaringe. Representa el 3 % de las consultas de guardia. El 30 % de los niños menores de 5 años presentan, al menos, un episodio de epistaxis. La edad media de presentación es entre los 7,5 y los 8,5 años. Predomina en el sexo masculino (el 56-67 %). La rinorrea es el síntoma más frecuentemente asociado (el 46 %). El origen puede ser anterior o posterior, y las anteriores son las más frecuentes. Es necesario un enfoque integral para determinar la etiología (primaria o secundaria). Los principales objetivos del tratamiento son el control de la hemorragia, de la causa subyacente y la prevención de la recurrencia.La mayoría de las hemorragias son autolimitadas; sin embargo, el taponamiento nasal y la cauterización son requeridos ante casos recurrentes o graves. Cuando estas técnicas fracasan, puede utilizarse un manejo endoscópico, angiografía-embolización y ligadura quirúrgica abierta

Epistaxis is defined as bleeding from the vestibule, nasal cavity or nasopharynx. It represents 3 % of Emergency Room consultations. Thirty per cent of children under 5 years of age have an episode of epistaxis. The average age of presentation is between 7.5 and 8.5 years. It predominates in males (56-67 %). Nasal obstruction (nasal discharge) is the most associated symptom (46 %). The origin can be anterior or posterior, with the previous ones being the most frequent. An integral approach is necessary to determine the etiology (primary or secondary). The main purposes of the treatment are bleeding control and the underlying cause and the prevention of recurrence. Most hemorrhages are self-limiting; however, nasal tamponade and cauterization are required in cases of recurrence and/or severity. When these techniques fail, endoscopic management, angiography-embolization, and open surgical ligation may be used.

Epistaxis: comparison of chemical cautery with topical vasoconstrictor in adult anterior epistaxis

Background: To compare efficacy of 75% silver nitrate chemical cautery as opposed to topical vasoconstrictor spray (xylometazoline 0.1%) in adult anterior epistaxis.Methods: This randomized controlled trial study was carried out at SMHS Hospital Srinagar from Jan 2019 to Dec 2019. 110 subjects that presented to ENT & HNS emergency with epistaxis and fulfilled the inclusion criteria were selected. Subjects were randomly distributed into two groups. Group-A individuals were treated by cauterization with 75% silver nitrate and Group-B individuals were treated with topical vasoconstrictor spray (xylometazoline 0.1%). All the subjects were reviewed at 1 month and success was determined in terms of control of epistaxis from same side of nose.Results: The mean age of the cohort was 48.5yrs (age range, 17-59). There were total 60 (54.4%) males and 50 (45.4%) females among the cases. Both the groups were comparable as regards the age, sex, duration and frequency of epistaxis. 91.2% cases in Group-A (silver nitrate cautery) and 73.5% cases in Group-B (xylometazoline spray 0.1%) had no further epistaxis at one-month follow-up (p=0.014).Conclusions: Chemical cauterization with silver nitrate is a feasible and safe technique for the treatment of adult anterior epistaxis and is more effective than topical vasoconstrictor spray.

Use Of Paper Patching And Tincture Ferri Perchloride For Day Care Management Of Tympanic Membrane Perforation

INTRODUCTION: Perforation of tympanic membrane constitutes a major portion of patients attending ENT OPD for which they are advised surgical procedures. Most of the cases with small perforations can be managed by doing OPD procedure of cautery patching and hence surgical procedure can be avoided. METHODS: The study was conducted in the tertiary hospital from August 2018 to July 2019. The patients were selected on the basis of the inclusion criteria after doing clinical examination, and audiometry. All the patients underwent cautery patching with tincture ferri perchloride and patch placed. The patients were followed up weekly till the perforation was completely closed or uptill 3 months. RESULTS: Total of 65 patients was included in the study. Most common etiology of perforation was inflammatory involving anteroinferior quadrant as most common etiology with success achieved in 56 patients. CONCLUSION: patients with small central dry perforation of tympanic membrane, cautery patching using tincture ferri per chloride and paper patching gives good results comparing to the surgical procedure, while ablating the morbidity and psychological trauma of the surgery.

Are critical size bone notch defects possible in the rabbit mandible?

OBJECTIVES: Small animal maxillofacial models, such as non-segmental critical size defects (CSDs) in the rabbit mandible, need to be standardized for use as preclinical models of bone regeneration to mimic clinical conditions such as maxillofacial trauma. The objective of this study is the establishment of a mechanically competent CSD model in the rabbit mandible to allow standardized evaluation of bone regeneration therapies. MATERIALS AND METHODS: Three sizes of bony defect were generated in the mandibular body of rabbit hemi-mandibles: 12 mm×5 mm, 12 mm×8 mm, and 15 mm×10 mm. The hemi-mandibles were tested to failure in 3-point flexure. The 12 mm×5 mm defect was then chosen for the defect size created in the mandibles of 26 rabbits with or without cautery of the defect margins and bone regeneration was assessed after 6 and 12 weeks. Regenerated bone density and volume were evaluated using radiography, micro-computed tomography, and histology. RESULTS: Flexural strength of the 12 mm×5 mm defect was similar to its contralateral; whereas the 12 mm×8 mm and 15 mm×10 mm groups carried significantly less load than their respective contralaterals (P<0.05). This demonstrated that the 12 mm×5 mm defect did not significantly compromise mandibular mechanical integrity. Significantly less (P<0.05) bone was regenerated at 6 weeks in cauterized defect margins compared to controls without cautery. After 12 weeks, the bone volume of the group with cautery increased to that of the control without cautery after 6 weeks. CONCLUSION: An empty defect size of 12 mm×5 mm in the rabbit mandibular model maintains sufficient mechanical stability to not require additional stabilization. However, this defect size allows for bone regeneration across the defect. Cautery of the defect only delays regeneration by 6 weeks suggesting that the performance of bone graft materials in mandibular defects of this size should be considered with caution.

Use Of Bipolar Cauterization In Circumcision

Male circumcision is done very frequently in all Pediatric surgery set up. Though several open and device based techniques of circumcision have been described in literature but no single procedure is taken as gold standard in terms of prevention of complications. In India, generally population are from tribal regions and due to non availability of resources dorsal slit technique is preferred and accepted but had complications like injury to urethra/glans, skin laceration, bleeding and infection. Bipolar cauterization holds its merits and demerits. In our experience the use of bipolar technique is safe, mostly complication free and gives good cosmetic outcome.

Corneal angiogenesis based on different protocols of alkaline cauterization in murine models

Abstract Purpose: To establish and compare protocols of alkaline cauterization for inducing corneal angiogenesis in murine models. Methods: Twenty-four adult Wistar rats were distributed into four groups (G1, G2, G3, and G4). The right eye cornea from each rat was cauterized using filter paper (3 mm), soaked in a solution of silver and potassium nitrates (3:1). Cauterization times were 10 (G1 and G4), or 20 seconds (G2 and G3). Cauterized corneas were washed with Ringer's lactate solution. The filter paper was either removed before washing (G1 and G2), or kept on the corneas (G3 and G4). Corneas were photographed at multiple time points (2, 4, 6, 8, 11, 13, and 15 days after the procedure), and neovascularization parameters were assayed. Results: Neovascularization was observed in 66% of G1 corneas, and 100% of G2, G3, and G4 corneas. On day 15, G1 corneas showed smaller vascularized areas (12.63 ± 12.59%) compared to those in the G3 (41.95 ± 17.32%) and G4 (33 ± 11.74%) (P < 0.05) groups. Conclusions: The silver and potassium nitrate solution effectively induced corneal angiogenesis. The G2, G3, and G4 protocols showed excellent reproducibility, and induced vascularization in 100% of corneas.

Resección de Pterigion nasal primario con autoinjerto limbo-conjuntival sin suturas / Sutureless limbal-conjunctival autograft for nasal pterygium surgery

Objetivo: Evaluar la efectividad y los síntomas en el postoperatorio de la resección de pterigion nasal primario con autoinjerto limbo-conjuntival sin suturas. Diseño del estudio: Estudio prospectivo e intervencional. Métodos: Se incluyeron 58 ojos de 58 pacientes con pterigion nasal primario que fueron llevados a resección con autoinjerto limbo-conjuntival; la fi jación del autoinjerto se realizó con cauterio en 29 pacientes y con sutura en 29 pacientes. Se realizó un seguimiento periódico de los casos por 24 meses y variables como el tiempo quirúrgico, el discomfort en el postoperatorio, el edema de la plastia, la inflamación ocular y las complicaciones fueron evaluadas y comparadas entre los subgrupos. Resultados: El tiempo quirúrgico promedio fue de 16 minutos para el grupo de fijación con cauterio y de 40 minutos en el grupo de fijación con suturas. El discomfort postoperatorio durante los primeros 15 días fue menor en el grupo de fijación con cauterio (p<0.001). No hubo diferencias entre los subgrupos en la tasa de recurrencia, pero el grupo de fijación con cauterio presentó una tasa mayor de dehiscencia de los bordes de la plastia (p<0.001) y del descenso conjuntival (p<0.001). Conclusiones: La resección del pterigion nasal primario con autoinjerto limbo-conjuntival fijado con cauterio es una técnica prometedora que lleva a un menor discomfort postoperatorio que la técnica convencional con suturas, tiene una baja tasa de recurrencias y requiere de un menor tiempo quirúrgico.

Objective: To evaluate the eff ectiveness and postoperative symptomatology of sutureless limbal-conjunctival autograft for pterygium surgery. Study design: Prospective and interventional study. Methods: 58 eyes of 58 patients with primary nasal pterygium that underwent pterygium resection with limbal-conjunctival autograft were included. Graft fi xation was done with cautery in 29 patients and with sutures in 29 patients. The patients were followed with periodic evaluations during 24 months. Surgical time, postoperative discomfort, graft edema, ocular inflammation, and complications were evaluated and compared between groups. Results: The average surgical time was 16 minutes for the cautery group and 40 minutes for the suture group. Postoperative discomfort during the first 15 days was statistically significant lesser for the cautery group (p<0.001). There was no difference in recurrence rate among groups; however, the cautery-fi xation group presented a significantly greater incidence of graft´s edges dehiscence (p<0.001), and superior conjunctiva dehiscence (p<0.001). Conclusions: Primary nasal pterygium resection with cautery-fi xated limbal-conjunctival autograft is a promising technique that causes less postoperative discomfort than conventional sutures, has a low recurrence rate and requires less surgical time.

Surgical Techniques for the Treatment of Tongue Tie in Children: A Comparative Study.

Introduction: Ankyloglossia is another name for tongue tie which in mild form is characterized by mucous membrane bands to complete ankyloglossia whereby the tongue is tethered to the floor of the mouth. It can affect feeding, speech, and oral hygiene [3] as well as have mechanical/social effects. Ankyloglossia can also prevent the tongue from contacting the anterior palate. Materials and Methods: The study aimed to find out best possible surgical modality of frenectomy by comparing scalpel, electro-cautery and CO2 laser in the treatment of tongue tie. This is a prospective randomized double blind clinical trial conducted in the department of ENT, Dr. Shankarrao Chavan Government Medical College, Nanded, Maharashtra. All patients were categorized in to three groups randomly as group A, group B and group C. Each group contains 18 patients and among group A, B and C, frenectomy was done by conventional scalpel technique, by bipolar cautery and CO2 laser respectively. Then patients were assessed on post-operation day 1 for symptomatology and inflammatory signs, on post-operation day 7 for wound healing and any complications and also after 1 month post-operation for scar and contracture of wound. Results: In our study, about 61% of population is of male and female were remaining 39% (ratio 1.6:1) which is matching with the previous studies. Amongst all patients most common age group is between 1-4 years of age group. Most of the patients were in Kotlow’s class III having severe ankyloglossia (3‑7 mm) followed by class i having Mild ankyloglossia (12‑16 mm). Conclusion: Laser and electro-cautery treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique.

Intralesional curettage and electrocauterization for the treatment of grade IA chondrosarcoma of long bones / 中华骨科杂志

Objective To explore the recurrence rate, the complications and functional status of 25 patients with grade I chondrosarcoma of long bones treated by intralesional curettage and electrocauterization, and to determine the feasibility and effi?cacy of this method for grade IA chondrosarcoma of long bones. Methods Twenty?five eligible patients treated in our hospital from May 2003 to December 2011, were collected in this study with a mean age of 49 years (range, 28-72 years). According to En?neking staging system, all the lesions were staged as IA. Patients received surgery of the lesion before were excluded. The involved bones were femur (13 patients), tibia (4 patients), and humerus (8 patients). During the operation, a large elliptical cortical window about the size of the longest dimension of the lesion was made to ensure the thorough exposure of the lesion and avoid inadequate curettage. The lesion was curettaged thoroughly after the cortical window was made, then the high speed bur drill was applied to clear away a thin layer of the reactive bone shell. After a thorough lavage of the cavity, electrocauterization was done alongside the cavity wall slowly twice. Allograft or artificial bone was used to fill in the cavity to enhance bone healing. If mechanical property of the long bone was endangered by the cortical window and the surgical procedure, plate and screws were applied to strengthen the bone to avoid post?operative fracture. Results All the 25 patients were followed up regularly. The period of follow?up was from 38 months to 142 months, with a mean time of 80 months. Calcification was observed clearly in all the lesions. The length of the le?sions varied from 4 cm to 11 cm, with an average length of 7 cm. Nineteen patients received a plate and screws fixation because the mechanical property of the affected bone, while the rest received no internal fixation. Deep infection occurred in 1 patient (4%, 1/25) two months after operation. Thorough debridement and packing of bone cement with antibiotics was done to control the infec?tion. The infection has been controlled till the latest follow?up at 62 months after operation. Local recurrence occurred in one pa?tient thirteen months after the primary operation. Tumor resection, mega?prosthesis replacement was applied to the patient. The pa?tient has been disease free till now for 67 months. Mean Musculoskeletal Tumor Society (MSTS) 93 functional score of all patients was 93%(range, 83%-100%). The five?year survival rate of these twenty?five patients was 100%. Conclusion Intralesional cu? rettage together with the application of high?speed bur drill and electrocauterization is an applicable method for grade I chondrosar?coma of long bones. The excellent functional result and low recurrence rate make it a favorable option for the selected cohort of pa?tients.

Prospective comparison of ligation and bipolar cautery technique in non-scalpel vasectomy

Objectives: There is no trial comparing bipolar cautery and ligation for occlusion of vas in non-scalpel vasectomy. This study aimed to compare the effectiveness of these vasectomy occlusion techniques. Materials and Methods: Between January 2002-June 2009, patients were allocated in alternate order. We recruited 100 cases in cautery group and 100 cases in ligation group. Non-scalpel approach was performed during vasectomy and fascial interposition was performed in all cases. First semen analysis was done 3 months after vasectomy. Vasectomy success was defined as azoospermia or non-motile sperm lower than 100.000/mL. Results: Four patients from the cautery group were switched to the ligation group due to technical problem of cautery device. Thus, data of 96 patients as cautery group and 104 patients as ligation group were evaluated. After vasectomy, semen analyses were obtained from 59 of 96 (61.5%) patients in cautery group and to 66 of 104 (63.5%) patients in ligation group. There was no statistical significant difference between the two groups in terms of the success of vasectomy (p=0.863). Conclusion: Although bipolar cautery technique is safe, effective and feasible in non-scalpel vasectomy, it has no superiority to ligation. There was no statistically significant difference in terms of the success and complications between the two groups.

Comparative Study of Monopolar Cautery and Bipolar Vessel Sealing System in Laparoscopic Appendectomy.

Background: Laparoscopic appendectomy has gradually become widespread especially in the last decade. Although laparoscopic techniques are similar, different instruments, such as endoscopic stapler, endoscopic clip, monopolar hook cautery, harmonic scalpel, and vessel sealing instrument, can be used in appendiceal mesentery dissection 1, 2. BVS is an effective and safe system to be used at the dissection of appendiceal mesentery and haemostasis and is definitely effective in decreasing the operation period. Objectives: The main objective of the present study was to studyretrospectively, the effects of using monopolar cautery and vessel sealing system on the operation period in the appendix mesentery dissection. Methods: Hundred patients, operated laparoscopically for acute appendicitis in between June 2010 and June 2011, are evaluated retrospectively. Monopolar cautery was used in 50 patients and bipolar vessel sealer was used in 50 patients. No intraoperative or postoperative complication was seen in any of the patients. None of the patients required conversion to open surgery due to dissection problems of the appendiceal mesentery. Results and Interpretation: The mean duration of operation was 51.08 min in the monopolar cautery group whereas 36.68 minutes in the bipolar vessel sealing system group. Conclusion: Bipolar vessel sealeris safer and time saving as compared toMonopolar cauteryin laparoscopic appendectomy.

Reducing Postoperative Pain from Tonsillectomy Using Monopolar Electrocautery by Cooling the Oropharynx

Objective: Evaluate intraoperative cooling of the oropharynx to reduce postoperative pain in tonsillectomy using monopolar electrocautery. Methods: Sixty-six patients, age 1 to 12 years, were selected for the study, 33 in the control group and 33 in the experimental group. After randomization, patients underwent subcapsular dissection and hemostasis with monopolar electrocautery. Patients in the experimental group had the oropharynx cooled after tonsil dissection and hemostasis for 10 minutes. The procedure was done through the oral cavity by irrigation with 500 mL of 0.9% saline, in temperatures between 5°C and 10°C, for 5 minutes. The evaluation of postoperative pain was made with the pain visual analog scale (VAS) for 10 days. As complementary data on the evaluation of pain, we recorded daily use of ketoprofen for pain relief. Results: Pain after tonsillectomy assessed by VAS was significantly lower in the experimental group at days 0, 5, and 6 (p < 0.05). There were no differences in the use of ketoprofen between the groups. Conclusion: Cooling of the oropharynx after tonsillectomy promotes clinically significant reduction in postoperative pain, without additional complications...

Screening of antiangiogenic potential of twenty two marine invertebrate extracts of phylum Mollusca from South East Coast of India

Objective: To evaluate the antiangiogenic potential of twenty two marine invertebrate species of Phylum Mollusca from south east coast of India.Methods:Live specimens of molluscan species were collected and their methanolic extracts were evaluated for preliminary antiangiogenic activity using the in ovo chick chorio-allantoic membrane assay. The extracts were further evaluated for in vivo antiangiogenic activity using chemical cautery induced corneal neovascularization assay in rats and oxygen induced retinopathy assay in rat pups.Results:In the chick chorio-allantoic membrane assay, four methanolic extracts of marine molluscan species viz. Meretrix meretrix, Meretrix casta, Telescopium telescopium and Bursacrumena methanolic extracts exhibited noticeable antiangiogenic activity at the tested concentration of 200 μg whereby they significantly inhibited the VEGF induced proliferation of new blood vessels. Among these four extracts, the methanolic extract of Meretrix casta exhibited relatively higher degree of antiangiogenic activity with an inhibitiory percentage (64.63%) of the VEGF induced neovascularization followed by the methanolic extracts of Telescopium telescopium (62.02%), Bursa crumena (60.48%) and Meretrix meretrix (47.01%). These four methanolic extracts were further evaluated for in vivo antiangiogenic activity whereby the methanolic extract of Telescopium telescopium exhibited most noticeable inhibition (42.58%) of the corneal neovascularization in rats in comparison to the sham treated group, and also exhibited most noticeable inhibition (31.31%) of the oxygen induced retinal neovascularization in rat pups in comparison to the hyperoxia group that was observed for considerable retinal neovascularization.Conclusions:The significant antiangiogenic activity evinced by the extract of Telescopium telescopium merits further investigation for ocular neovascular diseases.

Refractory acute suppurative thyroiditis secondary to pyriform sinus fistula

Acute suppurative thyroiditis is a rare disease because the thyroid gland is remarkably resistant to infection. We present a 2-year-old girl with refractory acute suppurative thyroiditis due to a pyriform sinus fistula (PSF). She complained of fever and painful anterior neck swelling. Her condition did not completely improved by multiple parenteral antibiotics along with incision and drainage. Barium esophagogram to detect PSF demonstrated no specific finding. Computed tomography scan showed air bubble superior to the left thyroid gland which indicated a possible fistula connected to the pyriform sinus. An intraoperative laryngoscopy revealed a 2-mm-sized fistula opening. The fistula was successfully treated by chemocauterization with trichloroacetic acid.
