RESUMEN

Gastric lipomas are rare benign tumours of the stomach, representing less than 3% of all benign gastric neoplasms. They are usually asymptomatic but larger lesions can present with abdominal pain, gastric outlet obstruction and haematemesis. Malignant transformation is extremely rare. Accurate preoperative diagnosis can be established with computed tomography. Being benign, extensive surgery is not necessary and simple excision of the lesion is adequate. Small asymptomatic lesions can be followed up. We present a case of 80-year-old woman with gastric submucosal lipoma who presented with haematemesis.

RESUMEN

OBJECTIVE: To evaluate the utility of brush cytology (BC) in diagnosing non-neoplastic and neoplastic lesions of the upper gastrointestinal (GI) tract. METHODS: The study comprised 106 brushings from 104 patients with clinically suspected lesions in the upper GI tract. Diagnoses were rendered on correlating brush cytological findings with clinicoradiological findings and compared with endoscopic biopsies (EB). An attempt was made to grade oesophageal squamous cell carcinomas (SCC) and to subcategorise gastric adenocarcinomas (AC). The sensitivity, specificity and predictive values of BC were calculated with respect to clinico-radiological outcome. RESULTS: Malignant and benign lesions on BC comprised 74.5% and 25.5%, respectively, and on histology, 64.2% and 28.3%, respectively. Twenty-one of 32 (65.6%) gastric ACs were accurately sub-typed (16 intestinal and five diffuse) and 25/36 (69.4%) oesophageal SCCs (7, 15 and three well, moderately and poorly differentiated, respectively) were accurately graded. On correlation with the final clinico-radiological diagnosis, there was one false-positive and no false-negative cases, respectively, on BC; three false-negative and no false-positive cases, respectively, on EB; eight EB were non-representative in which a diagnosis was not rendered, out of which seven were malignant. Thus, BC had a sensitivity and specificity of 100% and 96.4%, respectively, with a positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy (DA) of 98.7%, 100% and 99.1% (P ˂ 0.05), respectively. BC was superior to EB in detecting Candida species and EB in detecting Helicobacter pylori. CONCLUSIONS: BC is a useful, routinely applicable and reliable test for diagnosing upper GI lesions.

RESUMEN

BACKGROUND: Neoadjuvant chemotherapy has become the standard recommendation in the management of patients with locally advanced breast cancer. At present anthracycline based regimen such as CAF (cyclophosphamide, adriamycin and 5-FU) is widely used in clinical practice. The introduction of taxanes has revolutionized this field because of superior results. AIMS AND OBJECTIVES: This study is designed to compare the efficacy of paclitaxel plus doxorubicin regimen and CAF (cyclophosphamide, doxorubicin and 5-fluorouracil) regimen as neoadjuvant treatment of locally advanced breast cancer and to compare their toxicity profiles and also to correlate the hormonal receptor status in predicting response to the NACT. MATERIALS AND METHODS: In this prospective study, 101 patients with newly diagnosed locally advanced breast cancer were randomized to receive either CAF or Paclitaxel/adriamycin as NACT for three cycles. The response was assessed objectively using CT scans and applying RECIST criteria. The patients were monitored for hematologic, cardiac and other minor toxicities. RESULTS: There was a significantly increased complete and objective response seen in the AP group when compared to CAF group (24% and 58% in the AP group versus 7.8% and 39.2% in the CAF group, P value 0.0313 for complete response). The pCR rate was also significantly higher in the AP group compared to CAF group. (20.93% versus 4.34%, P value 0.0237). There was no significant difference between the groups with respect to cardiotoxicity and hematotoxicity. Patients with ER negative tumors have responded well to neoadjuvant chemotherapy better than ER positive patients. (Objective response 62.8% vs. 40%, P - 0.0473). CONCLUSIONS: Based on these results, taxane based regimen such as Paclitaxel/adriamycin can be recommended as a first line neoadjuvant regimen in patients with locally advanced breast cancer.

RESUMEN

BACKGROUND: Two-thirds of surgical site infections (SSI) because of Staphylococcus aureus are caused by Methicillin resistant Staphylococcus aureus (MRSA). This study was done to assess the efficacy of topical 2% mupirocin with 2% chlorhexidine gluconate body wash in decolonizing MRSA and its impact in preventing SSI because of MRSA. The various risk factors associated with MRSA carriers and SSI were also studied because of paucity of data in the developing world. METHODS: We did a non-randomised interventional trial in 602 patients undergoing elective general surgical operations. All patients in case (297) group were screened for MRSA and those positive were decolonised with topical 2% mupirocin calcium ointment and daily baths with 2% chlorhexidine antiseptic solution for 5 days. Control (305) group patients underwent surgery without decolonisation. Postoperatively, all patients were followed up for SSI for 30 days. RESULTS: Prevalence of MRSA carriers was 7.5% with decolonisation rate of 95.2%. The SSI incidence was 21.3%. The significant risk factors for SSI were type of anaesthesia (p = 0.002), duration of surgery (p = 0.001) and preoperative hospital stay (p = 0.001). There was a significant association between MRSA carrier positivity at the time of surgery and SSI (p = 0.041). CONCLUSIONS: There was no reduction in rate of SSI or other nosocomial infections in patients undergoing elective general surgical operations following preoperative MRSA decolonisation with 2% mupirocin and 2% chlorhexidine gluconate in MRSA carriers. MRSA carrier status was a significant risk factor for SSI but not for other nosocomial infections.

RESUMEN

Spontaneous choledochoduodenal fistulas (CDFs) are rare. The most common aetiology is penetrating duodenal ulcers, observed in 80% of cases. Even in areas where acid peptic disease is common, tuberculosis should be considered as a cause, especially in developing countries like India, where tuberculosis is common. The management of CDF due to acid peptic disease is predominantly surgical while healing of tuberculous CDF has been reported with antitubercular treatment. A preoperative diagnosis of tuberculous CDF by endoscopic biopsy from the duodenal ulcer or image guided fine needle aspiration if abdominal lymph nodes are present can eliminate the need for surgery and achieve a cure with antitubercular treatment. The CDF in this case was due to caseation of periduodenal lymph nodes rupturing into the duodenum and the bile duct.

RESUMEN

Necrotizing soft tissue infections (NSTIs) following elective hernia repair are extremely uncommon, though they can occur following emergency surgery for complicated hernias. They are also usually seen in individuals with impaired immunity. We report a case of fatal necrotizing fasciitis following elective hernia repair in an otherwise healthy young patient. A high index of suspicion is required to diagnose this condition early, as it is difficult to differentiate it from superficial surgical site infection.

RESUMEN

Primary perineal hernias are rare and can be a diagnostic challenge. We report the case of a 45-year-old female patient who presented with painless perineal swelling suggestive of perineal hernia. Computed tomography (CT) scanning revealed a pelvic mass herniating through the pelvic floor into the perineum. The lesion was completely excised by an abdominoperineal approach. Histopathological examination of the lesion revealed a leiomyoma. This case report suggests that the possibility of perineal herniation of a pelvic leiomyoma should be considered in a female patient with suspected primary perineal hernia. We recommend an abdominoperineal approach for the surgical management of such a lesion.
