Pancreaticobiliary tuberculosis diagnosed by endoscopic brushings.
CONTEXT: Isolated pancreaticobiliary involvement with tuberculosis is extremely unusual. Clinical manifestations include abdominal discomfort, weight loss, obstructive jaundice or pancreatitis. Mass/cystic lesions are seen on imaging studies and are often mistaken for pancreatic malignancy. Diagnosis is by demonstration of caseation necrosis or the presence of acid-fast bacilli on Ziehl Neelson staining in the aspirated or biopsied specimen. CASE REPORT: A 35-year-old man presented with pain in the upper abdomen of two-month duration associated with significant weight loss. Investigation showed elevated alkaline phosphatase. Imaging studies revealed a mass in the region of the head of the pancreas with dilated intra-hepatic biliary radicles. The diagnosis of pancreaticobiliary tuberculosis was confirmed by cytology from biliary brushing. Biliary brushings taken during endoscopic retrograde cholangiopancreatography have never previously confirmed the diagnosis of pancreaticobiliary tuberculosis. CONCLUSIONS: To the best of our knowledge, this is the first case report where the diagnosis was made on the basis of biliary brushings.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome: ultrasonography as a diagnostic tool.
Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome is characterized by symmetrical synovitis and swelling of both the upper and lower extremities. The anatomical determinant of RS3PE is predominantly extensor tenosynovitis as revealed by magnetic resonance imaging (MRI). Given the cost constraints, time, and expertise required in carrying out MRI and ease in diagnosing tenosynovitis by ultrasound, we utilized high-frequency ultrasonography (USG) for evidence of tenosynovitis of the distal tendons in patients with RS3PE. Diagnosis of tenosynovitis was made on the basis of anechoic or hypoechoic signals around the tendon sheaths in both transverse and longitudinal planes. Flexor and extensor tendons at the wrist and metacarpal heads and extensor digitorum longus (EDL) tendons at the ankle were evaluated with a 7.5-10-MHz linear probe. There were ten patients (seven males) with a mean age of 59.5 years (range: 52-78 years) and mean disease duration of 6.1 months (range: 1.5-12 months). Disease onset was acute in all of the cases. Pitting edema of the hands was present in all except two patients whereas four patients, in addition, had edema of the feet. Edema was symmetrical in seven patients. Inability to make a complete fist was noted in all. Tenosynovitis of extensor and flexor tendons at the wrist and the metacarpal heads was documented in all patients with edema of the hands. In seven cases extensor tendon tenosynovitis was more prominent compared to the flexor tendons. Tenosynovitis of EDL tendons was detected in six cases. Dramatic relief with low-dose prednisolone was noted in all patients within 6 weeks of therapy. At a mean follow-up of 10.1 months all patients had marked relief in edema of extremities and improvement in the grip strength. Our study confirms that tenosynovitis of both flexor and extensor tendons at the wrist and extensor tendons of the feet is the hallmark of RS3PE syndrome. USG is a reliable and cost-effective modality for evaluation of patients with suspected RS3PE.

Coeliac disease in developing countries: Middle East, India and North Africa.
Following the application of simple serological tests for the diagnosis of coeliac disease (CD) in the 1980s, it gradually became clear that the prevalence of CD in different countries in the Middle East, North Africa and India is almost the same as that in Western countries. The prevalence of CD in at-risk populations in these regions is reported to range between 3 and 20% and the prevalence in people with type 1 diabetes is approximately 3-5%. Clinical manifestations of CD vary markedly with age, the duration and the extent of disease. Clinical studies showed that presentation with non-specific symptoms or no symptoms is as common in the Middle East as it is in Europe. Wheat has been the major staple food in these regions for many centuries and it is possible that the continuous and high level of exposure to wheat proteins has induced some degree of immune tolerance, leading to milder symptoms, which are misdiagnosed as irritable bowel syndrome or unexplained gastrointestinal disorders. A high index of suspicion for CD should be maintained in all developing countries for patients who present with chronic diarrhoea or iron deficiency anaemia. The best method for diagnosing CD in patients with diarrhoea is the panel of coeliac serological tests followed by small-bowel biopsy. In the absence of supplies for a gluten-free diet in Middle Eastern countries, maintaining this diet represents a real challenge to both patients and clinicians.

Cerebral fat embolism as a rare possible complication of traumatic pancreatitis.
CONTEXT: Neurological complications following an acute attack of pancreatitis have been described. They are mainly in the form of encephalopathy, retinopathy and rarely polyneuropathy. Cerebral infarction following an acute attack of pancreatitis is very rare. CASE REPORT: We report the case of a 25 year old male, who developed multiple cerebral infarcts (both hemorrhagic and non-hemorrhagic) as a complication of acute pancreatitis. CONCLUSION: This is probably the first case report where a cerebral fat embolism during the course of acute pancreatitis has been hypothesized as a cause of cerebral infarction leading to hemiplegia.

Fine needle aspiration diagnosis of isolated pancreatic tuberculosis. A case report and review of literature.
CONTEXT: Tuberculosis is a common disease in the developing world and its incidence is slowly increasing in developed countries where a resurgence has been seen subsequent to the AIDS epidemic. Tuberculosis, in its extrapulmonary form, though emerging as a clinical problem, rarely affects the pancreas. The pancreas is biologically protected from being infected by Mycobacterium tuberculosis. Pancreatic tuberculosis presents with a wide spectrum of symptoms such as abdominal pain, constitutional symptoms, obstructive jaundice, iron deficiency anemia, pancreatic abscess, massive gastro-intestinal bleeding, acute/chronic pancreatitis, secondary diabetes, splenic vein thrombosis and a pancreatic mass mimicking malignancy. It should be suspected clinically in patients having a pancreatic mass, particularly if the patient is young, not jaundiced, coming from an area of high tuberculosis endemicity and having a normal endoscopic retrograde cholangio-pancreatography. Its indolent course and vague symptomatology along with non-specific laboratory and radiological findings call for greater vigilance. CASE REPORT: We report a case of pancreatic tuberculosis which presented with pancreatic pain. Imaging techniques revealed a mass located in the head of the pancreatic gland. Fine needle aspiration cytology revealed caseating granulomas. The diagnosis of pancreatic tuberculosis was made and the patient was put on anti-tubercular therapy. Five months later, a repeat CT scan of the abdomen revealed resolution of the pancreatic lesion. CONCLUSION: The diagnosis of pancreatic tuberculosis is usually not suspected prior to laparotomy. Most patients have been diagnosed at laparotomy, thus fine needle aspiration cytology/biopsy is useful in obviating the need for major surgery with its accompanying morbidity. Exploratory laparotomy may be required in technically difficult cases due to risk of injury to the vessels in the vicinity of the mass.

Comparative analysis of duodenal biopsy tissue orientation supported on vegetable matrix versus filter paper.
BACKGROUND: Biopsy tissue may get disoriented if filter paper is used as a supporting medium. Use of vegetable matrix (cucumber) as a supporting medium may obviate the need of lifting the tissue while making blocks and thus avoid disorientation that occurs during this step. OBJECTIVE: To compare the orientation of duodenal biopsy tissue supported on vegetable matrix (cucumber) and on filter paper. METHODS: Over one year, 40 patients (20 with large-volume diarrhea, 20 with dyspepsia) were included in the study. Two pairs of duodenal biopsy tissues were obtained during gastroscopy; one pair was placed on filter paper, the other on vegetable matrix. Tissue and vegetable matrix were embedded together while making blocks, whereas the tissue had to be lifted off in case of filter paper. Sections were stained and assessed for crypt-villous alignment, parallel orientation of crypts and presence of visible muscularis mucosae with the help of a scoring system. RESULTS: Compared to biopsy tissue supported on filter paper, vegetable matrix-supported tissues were better oriented. Scores were rated as bad, good and very good in 8, 11 and 21 vegetable matrix-mounted tissues and in 21, 11 and 8 filter paper-mounted tissues, respectively. CONCLUSION: Duodenal biopsy tissue supported on vegetable matrix (cucumber) is better oriented than that on filter paper.

Achalasia cardia in mother and son.
Familial occurrence of achalasia cardia is rare. Most associations are among siblings or in monozygotic twins. Parent-child association is even rarer and only six such instances have been reported till date. We report a 29-year-old man with achalasia cardia and his mother who had the same illness two and half years later. Both of them were successfully treated with balloon dilatation.
