Endonasal carbon-dioxide laser assisted dacryocystorhinostomy verses external dacryocystorhinostomy

This is a prospective, non-randomized study to evaluate and compare the results, morbidity and surgical time for endonasal carbon-dioxide laser assisted dacryocystorhinostomy and external dacryocystorhinostomy. 70 consecutive patients of chronic dacryocystitis with nasolacrimal duct obstruction were selected for the study. 36 patients under went endonasal CO2 laser assisted dacryocystorhinostomy and 34 had external dacryocystorhinostomy. Selection of the type of operation was left to the patient's choice. All the patients had preoperative counseling and both the procedures were explained in detail with their advantages and disadvantages. Patients not willing for the external incision were selected for endonasal laser assisted dacryocystorhinostomy and others were operated via external approach. Silicone tubes were put in all the patients for three months after surgery. The final follow up was 12 months after the removal of silicone tubes. The patency of the lacrimal passage was confirmed by irrigation, and patients were questioned about their symptoms. The success rates, 12 months after removal of silicone tubes were 100% in endonasal CO2 laser assisted dacryocystorhinostomy and 88.24% in external dacryocystorhinostomy. The surgical time of endonasal laser assisted dacryocystorhinostomy was 38 minutes as compared to 62 in external dacryocystorhinostomy. Complication rate in both groups was almost equal. Thus, we came to the conclusion that Endonasal CO2 laser assisted dacryocystorhinostomy is a better surgical option to external dacryocystorhinostomy in cases of chronic dacryocystitis with nasolacrimal duct obstruction, with shorter surgical time.     

Infusion manometry and detection of sphincteric function of crural diaphragm

The principles of infusion manometry in the measurement of lower esophageal sphincter (LES) pressure were laid down in the mid-1960s by L.D. Harris and his coworkers. Dodds and his colleagues were largely responsible for the improvements and advent of the low-compliance manometry. Using side-hole manometry, it is possible to detect accurate LES pressure that correlates with the strength of the antireflux barrier. The LES pressure as measured by the side-hole manometry, shows respiration-induced pressure oscillations. These pressure oscillations were initially thought to be due to the influence of abdominal and thoracic pressures on the LES. However, it was later pointed out that these pressure oscillations were due to the relative motion of the point pressure sensor (side hole of the manometric catheter) and the LES during respiration. Recent studies suggest that active contraction of the crural diaphragm during inspiration is responsible for the pressure oscillations observed in the cat LES pressure tracings. The use of the sleeve device in the measurement of LES pressure during contraction of the diaphragm has been described recently. Using the principles of manometry and sleeve device, it is now possible to identify two lower esophageal sphincters: the smooth muscle LES, traditionally known as the LES, and crural diaphragm, which we have referred to as the external lower esophageal sphincter. The purpose of the following paper is to summarize the general principles of the infusion manometry in the measurement of intraluminal pressure, specifically the LES pressure. The recently developed technique of detection of the sphincteric function of the crural diaphragm by the sleeve device will be discussed. In the last paragraph the limitations of manometry in detection of the muscular contractile activity are described.     

Stylalgia

Stylalgia is an important cause of paroxysmal dull pain in the throat and ear. Enlarged styloid process is the ossification stylohyoid ligament. Pain is aggravated by the act of deglutition. Pain due to enlarged styloid process may be attributed to the Glassopharyngeal Neuritis or stiff bony clasp formation. Styloidectomy, by any route, is a satisfactory mode of treatment in such cases. In cases with prolonged illness or no response with styloidectomy, Glassopharyngeal Neurectomy may be taken up.     

Bilateral posterior lens dislocation in Marfan's syndrome

Complete dislocation of the lens is a rare feature of Marfan's Syndrome. We observed four cases of bilateral complete posterior dislocation of the lens in established cases of Marfan's Syndrome over a one year period. An ophthalmologist may encounter infrequently, unilateral posterior dislocation in one eye and ectopia lentis in the other, but bilateral spontaneous posterior dislocation is rare. All our cases had associated vitreous degeneration with vitreous herniating into the anterior chamber. The pathogenesis of complete posterior dislocation in Marfan's Syndrome is discussed.     

Development and evaluation of a breast cancer prevention decision aid for higher-risk women

Objective To develop and evaluate the effectiveness of a breast cancer prevention decision aid for women aged 50 and older at higher risk of breast cancer. Design Pre‐test–post‐test study using decision aid alone and in combination with counselling. Setting Breast Cancer Risk Assessment Clinic. Participants Twenty‐seven women aged 50–69 with 1.66% or higher 5‐year risk of breast cancer. Intervention Self‐administered breast cancer prevention decision aid. Main outcome measures Acceptability; decisional conflict; knowledge; realistic expectations; choice predisposition; intention to improve life‐style practices; psychological distress; and satisfaction with preparation for consultation. Results The decision aid alone, or in combination with counselling, decreased some dimensions of decisional conflict, increased knowledge (P < 0.01), and created more realistic expectations (P < 0.01). The aid in combination with counselling, significantly reduced decisional conflict (P < 0.01) and psychological distress (P < 0.02), helped the uncertain become certain (P < 0.02), and increased intentions to adopt healthier life‐style practices (P < 0.03). Women rated the aid as acceptable, and both women and practitioners were satisfied with the effect it had on the counselling session. Conclusion The decision aid shows promise as a useful decision support tool. Further research should compare the effect of the decision aid in combination with counselling to counselling alone.     

External duodenal fistula following closure of duodenal perforation.

AIM: Retrospective analysis of experience with management of external duodenal fistula (EDF) without using total parenteral nutrition (TPN). METHOD: Medical records of 31 patients with EDF following closure of duodenal ulcer perforation, treated over a 7-year period (1994-2001), were studied. Twenty-one patients (68%) had evidence of sepsis at presentation or during the course of treatment. None could afford TPN for optimum time. All patients received hospital-based enteral nutrition through nasojejunal tube, besides supportive medical treatment and/or surgery. Peritonitis or failure to insert nasojejunal tube for enteric alimentation led to early surgery. RESULTS: Two patients died of septicemia and multi-organ failure within 48 hours of admission. Fourteen patients (48.3%) initially received conservative treatment (Group I); six of them later required surgery. Fifteen patients (51.7%) underwent early surgery due to peritonitis (n=9) or failure to establish enteral feeding (n=6) (Group II); wound infection, intra-abdominal abscess and septicemia were more common in these patients than those in Group I. Survival rate was higher in Group I than in Group II (86% versus 40%; p< 0.05). Septicemia and gastrectomy were the independent factors associated with high mortality. CONCLUSIONS: EDF can be satisfactorily managed without TPN. Successful placement of enteral feeding line, supportive treatment and delayed surgery can achieve survival in 85% of patients. Minimum intervention is recommended when early surgery is performed in peritonitis or to establish enteral feeding line.     

Scleromyxoedema with features of systemic sclerosis.

The case is described of a patient with scleromyxoedema with features typical of systemic sclerosis. The features were so characteristic that the disease was misdiagnosed as systemic sclerosis. A brief review of the association of the two diseases is given.     

Carotid Stent-Supported Angioplasty via Radiobrachial Route

Endovascular stent-supported angioplasty is a treatment option for atherosclerotic disease of the cervical internal carotid artery in high-risk patients. The traditional transfemoral approach is not suitable for patients who suffer from common femoral artery or abdominal aorta atheropathy. We report a case of carotid stent deployment using the radial route in a 68-year-old man with type B aortic dissection, having severe right internal carotid artery origin stenosis, presenting with ipsilateral retinal ischemic events. Technical aspects of carotid stenting via the radial approach are described and the related literature is discussed.
