Heterotopic Pancreatic Pseudocyst Radiologically Mimicking Gastrointestinal Stromal Tumor

Heterotopic pancreas is a relatively common variant of foregut embryologic dystopia that can be described as pancreatic tissue found outside the normal anatomic location, being independent from vascular supply of normal pancreas. Having all features of pancreatic tissue except for the major duct structures, this ectopic tissue may be clinically recognized when pathologic changes take place. Inflammation, hemorrhagic or obstructive states, and eventually malignancy-related problems may become a diagnostic challenge for clinician and finally lead to consequences of misdiagnosis. In this article we will discuss a case of heterotopic pancreatic tissue located in gastric cardia, which was diagnosed preoperatively as gastrointestinal stromal tumor.Key words: Ectopic pancreas, Pseudocyst, Gastrointestinal stromal tumor, MisdiagnosisHeterotopic (ectopic) pancreas is defined as the presence of pancreatic tissue in an aberrant site that is not anatomically and vascularly connected to the pancreas proper.^1,2 Ectopic pancreatic tissue is most commonly found in the duodenum (particularly the second portion), ampulla, stomach (prepyloric antrum), and upper jejunum; it can also occur in the liver, biliary tract, Meckel''s diverticulum, and several other sites such as large bowel, spleen, omentum, mediastinum, lung, thyroid, and even brain.^1–6 The heterotopic pancreatic tissue is usually located in the submucosa and/or the muscularis or subserosa.^1,2,4Practically any pancreatic pathology can also occur in the heterotopic pancreatic tissue including acute pancreatitis and neoplastic transformation.^1,4,7,8 Episodes of acute pancreatitis may cause local inflammation and typical pancreatitis-related complications in the host organ. The ectopic pancreatic tissue can lead to ulceration and bleeding in the cases located beneath a mucosa. Being a mass-forming lesion, it may also result in luminal obstruction (particularly in the prepyloric antrum).^1,4Although it is a relatively common congenital anomaly (0.5% to 13% in autopsy series), in most cases heterotopic pancreas remains clinically silent and is found incidentally during surgery or an endoscopic and/or radiological investigation.^1,9 Heterotopic pancreas may be confused with other solid tumors of the host organ.Heterotopic pancreas in the stomach is usually located in the prepyloric area.¹⁰ We report here an unusual case of heterotopic pancreas with a pseudocyst formation in the gastric cardia mimicking gastrointestinal stromal tumor.     

The Feasibility of Hepatic Resections Using a Bipolar Radiofrequency Device (Habib?)

The bipolar radiofrequency device (Habib®) has been recently introduced in order to reduce intraoperative bleeding for a safe hepatic resection as an alternative to the conventional tools. However, indications, perioperative findings, and outcome of the device for hepatic resections remain and deserve to be analyzed. The current study aims to analyze the feasibility of the bipolar radiofrequency device (Habib®) for hepatic resections. Information of the patients that underwent hepatic resection using with the Habib® device between 2007 and 2011 was abstracted. Patient, disease, and operation-related findings and perioperative data were investigated. A total of 71 cases (38 [53.5 %] males, mean age was 56.8 ± 11.9) were analyzed. Metastatic disease (n = 55; 77.5 %) was the leading indication followed by primary liver and biliary malignancies (n = 7; 9.9 %), hemangioma (n = 5; 7 %), hydatid disease (n = 3; 2.8 %), and hepatic gunshot trauma (n = 1; 1.4 %). Metastasectomy was the most commonly performed procedure (n = 31; 56.3 %), but in 24 (77.4 %) cases, it was performed in addition to extended resections. Other procedures in the study patients include segmentectomy in 17, bisegmentectomy in 19, trisegmentectomy in 17, right or left hepatectomy in 8, and extended right/left hepatectomy in 3. The mean (±SD) operation time was 241.7 ± 78.2 min. The median amount of bleeding was 300 cc (range 25–2500), and 23 (32.4 %) cases required perioperative transfusion. The median hospitalization period was 5 days (range 1–47). Lengthened drainage (n = 9, 12.7 %) and intraabdominal abscess (n = 8, 11.23 %) were the most common problems. Hepatic resections using the Habib® device seem to be feasible in cases with primary and metastatic hepatic lesions and benign liver masses and even those with hepatic trauma. It may lessen the amount of intraoperative hemorrhage, although lengthened drainage and intraabdominal abscess were the major postoperative problems in these cases.     

Development and treatment approaches of bronchopleural fistula after pulmonary resection

Pulmonary resections comprise most of the operations performed in thoracic surgery departments. Diseases like pulmonary cancers, bronchiectasis, pulmonary abscess, tuberculosis and fungal infections are treated surgically by pulmonary resections. One of the important steps of the pulmonary resection is to suture the bronchi through which the air is supplied to the resected pulmonary tissue. Bronchopleural fistula developed in the bronchial stump is encompassed as one of the most important factors affecting mortality and morbidity regarding postoperative complications.     

Visceral basidiobolomycosis: An overlooked infection in immunocompetent children

Visceral basidiobolomycosis is an unusual fungal infection of viscera caused by saprophyte Basidiobolus ranarum. It is very rare in healthy children and poses a diagnostic challenge due to the non-specific clinical presentation and the absence of predisposing factors. We report a case of gastrointestinal basidiobolomycosis in a 4-year-old healthy girl who presented with a short history of abdominal pain, bleeding per rectum, fever, and weight loss. The diagnosis was based on high eosinophilic count, classical histopathology findings of fungal hyphae (the Splendore-Hoeppli phenomenon), and positive fungal culture from a tissue biopsy. Fungal infection was successfully eradicated with a combined approach of surgical resection of the infected tissue and a well-monitored course of antifungal therapy. The atypical clinical presentation, diagnostic techniques, and the role of surgery in the management of a rare and lethal fungal disease in an immunocompetent child are discussed.Key words: Basidiobolomycosis, child, fungal infection, gastrointestinal, immunocompetent     

Experiences on the efficacy and safety of nalidixic acid,oxolinic acid,cinoxacin and norfloxacin in the treatment of urinary tract infections (UTI)

Summary The purpose of this study was to determine the effectiveness and tolerability of norfloxacin, cinoxacin and oxolinic acid in the treatment of urinary tract infections (UTI) in comparison to nalidixic acid. 125 patients were given the drugs in the appropriate doses for 10–14 days and 30 patients were treated for six weeks. Clinical, bacteriological, hematological and chemical checks were made on all patients before and after treatment. It was found that norfloxacin, cinoxacin and oxolinic acid are safe and effective againstEscherichia coli, Klebsiella andProteus, the commonly encountered organisms in urinary tract infections. The cure rate for norfloxacin was 93%, for cinoxacin 83%, for oxolinic acid 80% and for nalidixic acid 70% in the short course. However, these differences were not statistically significant. Oxolinic acid, cinoxacin and norfloxacin have the advantage over nalidixic acid of being administered only twice daily.

Erfahrung mit Nalidixinsäure, Oxolinsäure, Cinoxacin und Norfloxacin bei der Behandlung von Harnwegsinfektionen — Wirksamkeit und Sicherheit

Zusammenfassung In der vorliegenden Studie sollte die Wirksamkeit und Verträglichkeit von Norfloxacin, Cinoxacin und Oxolinsäure im Vergleich zu Nalidixinsäure bei der Behandlung von Harnwegsinfektionen geprüft werden. 125 Patienten erhielten die Medikamente in den entsprechenden Dosen 10 bis 14 Tage lang, 30 Patienten wurden über sechs Wochen behandelt. Klinische, bakteriologische, hämatologische und biochemische Untersuchungen wurden bei allen Patienten vor und nach Behandlung vorgenommen. Norfloxacin, Cinoxacin und Oxolinsäure erwiesen sich als sicher und wirksam gegen Infektionen mitEscherichia coli, Klebsiella undProteus, die üblichen Erreger der Harnwegsinfektionen. Die Heilungsrate für Norfloxacin betrug 93%, für Cinoxacin 83%, für Oxolinsäure 80% und für Nalidixinsäure 70% bei der kürzeren Therapiedauer. Die gefundenen Unterschiede waren jedoch statistisch nicht signifikant. Oxolinsäure, Cinoxacin und Norfloxacin haben gegenüber Nalidixinsäure den Vorteil, daß sie nur zweimal täglich verabreicht werden müssen.

     

The Evaluation of Left Ventricular Functions with Tissue Doppler Echocardiography in Adults with Celiac Disease

Background/Aim:

The aim of this study was to investigate the effects of celiac disease on cardiac functions using tissue Doppler echocardiography (TDE).

Patients and Methods:

The study included 30 patients with celiac disease (CD) and 30 healthy volunteers. Echocardiographic examinations were assessed by conventional echocardiography and tissue Doppler imaging. The peak systolic velocity (S^''m), early diastolic myocardial peak velocity (E^''m), late diastolic myocardial peak velocity (A^''m), E^''m/A^''m ratio, myocardial precontraction time (PCT^''m), myocardial contraction time (CT^''m), and myocardial isovolumetric relaxation time (IVRT^''m), E to E^''m ratio were measured.

Results:

In pulsed wave Doppler echocardiography, mitral late diastolic flow (A) velocity and E to E^''m ratio were significantly higher (P = 0.02 and P = 0,017), E/A ratio was significantly lower (P = 0.008) and IVRT was significantly prolonged (P = 0.014) in patients with CD. In TDE, S^''m, E^''m, and E^''m/A^''m ratio were significantly lower, IVRT^''m was longer (P = 0.009) from septal mitral annulus and S^''m, E^''m, E^''m/A^''m ratio were significantly lower, PCT^''m, PCT/ET ratio, IVRT^''m were longer, and MPI was higher from lateral mitral annulus in celiac group than controls.

Conclusion:

Our study confirms that patients with CD have impaired diastolic function. More importantly, we also demonstrated an impairment of myocardial systolic function in patients with CD by TDE. We recommend using TDE in addition to conventional echocardiography parameters for the cardiovascular risk assessment of patients with CD.
