ABSTRACT
GOALS: To study the factors that influence the cellularity and adequacy of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). BACKGROUND: An on-site cytopathology service is preferred during EUS-guided FNA. However, this is not always available. Factors that influence the aspirate cellularity and adequacy have not been well defined in the absence of on-site cytopathology. STUDY: EUS-guided FNA procedures without an on-site cytopathologist from a single center were retrospectively studied. FNA of solid masses and lymph nodes (LN) were included. The FNA cellularity, hemorrhagic content, and endoscopists' assessment of adequacy were analyzed. RESULTS: A total of 166 patients from January 2009 to October 2010 were included. A total of 520 FNA passes were performed. Of the 166 lesions, 70 (42.2%) were solid masses and 96 (57.8%) were LNs. A 22-G needle was used in 72.3% and 25 G in 27.7% of the patients. The median (range) number of FNA passes was 3 (1 to 7) for LNs and 3 (1 to 5) for solid masses. With this, the endoscopists had an accuracy of 92.2% (153/166) for obtaining an adequate aspirate. Of the 166 samples, 4 (2.4%) were acellular, 20 (12.0%) sparsely cellular, 52 (31.4%) moderately cellular, and 90 (54.2%) highly cellular. The 25-G needle had significantly more adequate aspirates than the 22-G needle for solid masses (P=0.011). Also, increasing passes correlated with higher cellularity (P=0.002) and an adequate aspirate (P=0.021). No correlation was found for LN FNA. Lesion size did not influence the cellularity or adequacy (P>0.05). The degree of hemorrhage was not influenced by the needle gauge, number of passes, or lesion size. The diagnostic yield was not affected by hemorrhage in the sample (P>0.05). CONCLUSIONS: EUS-guided FNA obtains a high proportion of adequate aspirates for LNs and solid masses, even without an on-site cytopathologist. Small proportions of inadequate samples still occur. For solid masses, a 25-G needle with at least 3 passes is more likely to provide an adequate aspirate than a 22-G needle and fewer passes. Hemorrhage did not affect the cytopathology's ability to make a diagnosis.

Plasmodium falciparum and Plasmodium vivax malaria are endemic infections in India and are commonly associated with mild hematological abnormalities. Severe thrombocytopenia is common in isolated falciparum and mixed falciparum/vivax malaria, but is very rare in isolated P.vivax infection. We hereby report a case of severe thrombocytopenia (platelet count of 8x10(9)/L) in a case of vivax malaria. This is only the second case ever reported in the literature of such profound thrombocytopenia in a case of isolated P.vivax malaria.

Heparin and insulin stimulate lipoprotein lipase and are known to decrease serum triglyceride levels. However, their efficacy in hypertriglyceridemia-induced acute pancreatitis is not well documented. We report a 51-year-old man in whom treatment with heparin and insulin was accompanied by reduction in serum triglyceride levels and resolution of pancreatitis.

Hepatitis E virus is one of the leading causes of acute viral hepatitis in India but usually manifests as a mild self-limiting illness. Viral hepatitis in the presence of glucose-6-phosphate dehydrogenase (G6PD) deficiency may be associated with complications such as severe anemia, hemolysis, renal failure, hepatic encephalopathy and even death. The incidence of G6PD deficiency in the general population of northern India is reported to be between 2.2% and 14%. Despite both hepatitis E infection and G6PD deficiency being common, their impact on patient illness has only recently been reported. The present study reports a case of severe hemolysis in a patient with G6PD deficiency and hepatitis E infection.
ABSTRACT
BACKGROUND: Burning pain in the feet has been known to occur as a distinct clinical symptom for almost two centuries. Despite being a common and fascinating clinical entity, this syndrome has received scant attention in the medical literature and has been described only in anecdotal reports. OBJECTIVE: This article describes and discusses the various aspects of this intriguing syndrome. DISCUSSION: Burning feet syndrome (BFS) is a common disorder especially among the elderly and is frequently encountered in general practice. There is no specific aetiology and it can occur as an isolated symptom or as part of a symptom complex in a variety of clinical settings. In contrast to the presence of distressing subjective symptoms, the physical examination is marked by a paucity of objective signs. The pathophysiology of BFS is not very clear and treatment varies depending on the aetiology.

Patients are often ill-equipped to know which speciality to choose for their health problem. Especially in the presence of non-specific symptoms, choosing the right specialist might not be so obvious. In such cases, misdirected self-referrals by patients to self-chosen specialists can sometimes lead to misdiagnosis resulting in unwarranted delays in getting the right treatment. The general physicians, on the other hand, are in a unique position to oversee the big picture of patients' health, and are therefore better equipped to identify and sort out their individual health problems. Hence instead of a specialist if the first place of contact for patients is a general physician, they are likely to be guided along the right path of treatment for their various health problems. Such a system will minimize errors on the part of the patients by making certain that they are referred to the appropriate specialists.

AIM: Ampullary tumors are rare. Reports on ampullary tumor staging are heterogeneous and combine both periampullary and ampullary tumors. This study assessed the performance of endoscopic ultrasound (EUS) in the local staging of ampullary tumors only. METHODS: Data were collected retrospectively. We included patients with an ampullary tumor who underwent EUS and surgical resection. Tumor (T) and nodal (N) TNM staging for EUS and histopathological (HP) staging were compared. RESULTS: From 2009 to 2010, a total of 79 patients with ampullary tumors were identified. Of these, 26 had both EUS and Whipple's surgery and were included (28 did not undergo resection, 13 had palliative surgery only and 12 had resection without EUS). For T staging by HP, there were 2 (7.7 %) T1, 11 (42.3 %) T2, 12 (46.2 %) T3 and 1 (3.8 %) T4 tumors. The accuracy of EUS T staging was 73.1 % with a Kappa value of 0.564 (p < 0.0001). The sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) of EUS, respectively were 50.0 %, 91.7 %, 33.3 % and 95.7 % for T1 tumors; 81.8 %, 80.0 %, 75.0 % and 85.7 % for T2; 75.0 %, 92.9 %, 90.0 % and 81.3 % for T3 tumors. For N staging by HP, 17 (65.4 %) were N0 and 9 (34.6 %) N1. The N staging diagnostic accuracy was 80.8 % with a Kappa value of 0.586 (p = 0.003). The sensitivity, specificity, PPV, NPV for N0 disease were 82.4 %, 77.8 %, 87.5 % and 70.0 %, respectively while for N1 they were 77.8 %, 82.4 %, 70.0 % and 87.5 %, respectively. CONCLUSIONS: EUS had a moderate strength of agreement with histopathology for both T and N staging, and a high diagnostic accuracy for nodal staging.

Direct endoscopic views of bile duct have been described in literature since the 1970s. Since then rapid strides have been made with the advent of technologically advanced systems with better image quality and maneuverability. The single operator semi-disposable per-oral cholangioscope and other novel methods such as the cholangioscopy access balloon are likely to revolutionize this field. Even though cholangioscopy is currently used primarily for characterization of indeterminate strictures and management of large bile duct stones, the diagnostic and therapeutic indications are likely to expand in future. The following is an overview of the currently available per-oral cholangioscopy equipments, indications for use and future directions.
ABSTRACT
Achalasia cardia is a motility disorder of the esophagus characterized by failure of relaxation of the lower esophageal sphincter. Nitrates and calcium channel blockers, pneumatic dilatation, botulinum toxin injection and surgical myotomy have been described in literature as possible management options. We present a patient who presented with achalasia and was co-incidentally diagnosed to have cryptogenic cirrhosis with portal hypertension and had esophageal varices. This clinical combination precluded the use of pneumatic dilatation and surgical myotomy. We injected botulinum toxin into the lower esophageal sphincter using a celiac plexus neurolysis needle under endoscopic ultrasound guidance; the clinical response was good.
