Acute Pancreatitis Complicating Acute Hepatitis E Virus Infection: A Case Report and Review

Hemanta K Nayak; Nitish L. Kamble; Nishant Raizada; Sandeep Garg; Mradul Kumar Daga

Acute pancreatitis complicating fulminant viral hepatitis has been well recognized; however, acute pancreatitis occurring in nonfulminant hepatitis is very rare. The case presented describes moderate pancreatitis in a young male, manifesting during the course of nonfulminant acute hepatitis E infection. The diagnosis of acute viral hepatitis E was confirmed by serology and reverse transcriptase polymerase chain reaction (RT-PCR) to demonstrate Hepatitis E virus (HEV) RNA in both stool and serum. Patients with acute viral hepatitis presenting with severe abdominal pain should have a diagnosis of acute pancreatitis suspected and appropriate investigations including serum amylase, lipase, biliary ultrasonography and/or contrast-enhanced computed tomography of the abdomen should be undertaken. The identification of this unusual complication of Hepatitis E is important; however, the prognosis for patients with Acute Pancreatitis Complicating Acute Hepatitis E Virus Infection is good, and uncomplicated recovery with conservative treatment is expected.

We present here a case of young male with complaints of fever and swelling in the neck for eight months. History of progressive weakness associated with weight loss was present. Physical examination revealed pallor, multiple enlarged cervical lymph nodes and hepatosplenomegaly. Investigations showed pancytopenia, hyperglobinemia and Leishman-Donovan bodies on bone marrow aspiration. Serological test confirmed diagnosis of visceral leishmaniasis. However, cervical lymph node aspiration and biopsy were suggestive of Mixed cellularity Hodgkins disease. This made it a very rare case of Leishmaniasis as an opportunistic infection in a patient of pre-chemotherapy Hodgkins disease. There was marked improvement in haematological profile and regression of hepatosplenomegaly with Amphotericin B treatment followed by favourable response to chemotherapy. The case emphasizes the suspicion for leishmaniasis as a masquerader and as an opportunistic infection in haematological malignancies.

Diagnostic dilemma: Kikuchi's disease or tuberculosis?

Hemanta K Nayak; Pankaj Kumar Mohanty; Saumyaranjan Mallick; Avishek Bagchi

Any patient from a tuberculosis (TB) endemic area such as India with classical clinical features of fever, weight loss and lymphadenopathy, making a diagnosis of Kikuchis disease (KD) prior to waiting for the 6-week culture is not appropriate. KD or histiocytic necrotising lymphadenitis is a rare self-limiting cervical lymphadenitis, often a diagnosis of exclusion. One needs to exclude TB, sarcodosis, lymphoma and autoimmune diseases to make such a diagnosis. The patient here with classical clinical presentation of TB with lymph node biopsy mimicking KD (biopsy and immunohistochemistry) posed a big diagnostic dilemma. However, culture of the biopsied lymphatic tissue was confirmed to be mycobacterium TB after the 6th week of incubation. The patient was treated with antitubercular drugs initially, and later, steroid was added in view of his persistent symptoms and he responded. One should wait for the tissue culture report to confirm or exclude the diagnosis of TB. Exclusion should not be based only on laboratory criteria. Histopathogically, TB can mimic any other granulomatous disorder.

Delayed presentation of congenital diaphragmatic hernia presenting with intrathoracic gastric volvulus: a case report and review

Hemanta K Nayak; Gaurav Maurya; Neha Kapoor; Premashis Kar

Acute gastric volvulus associated with congenital diaphragmatic hernia is an unusual surgical emergency and its presentation in adulthood is extremely rare. Gastric volvulus is an uncommon condition which is difficult to diagnose and treat. This case describes a middle aged man presenting with post-traumatic acute abdomen and finally being diagnosed as a case of gastric volvulus due to congenital diaphragmatic hernia which was till now asymptomatic and undiagnosed. Clinical examination and chest x-ray was suggestive of hiatus hernia. Contrast-enhanced CT of thorax and abdomen revealed hiatus hernia and gastric volvulus. A provisional diagnosis of post-traumatic hiatus hernia with associated gastric volvulus was made and was operated on an emergency basis. Surprisingly, the intraoperative findings revealed significant adhesions near the diaphragm suggestive of congenital diaphragmatic hernia. Hence, a diagnosis of gastric volvulus due to congenital diaphragmatic hernia was made which remained asymptomatic and undiagnosed till adulthood. He responded well to operative management and remained asymptomatic afterwards.

We present a case of a young male who presented with complaints of fever along with cough and sputum. He was diagnosed with having right pleural effusion. He was already taking anti-tubercular therapy for one month before presentation. He was started on intravenous antibiotics and continued on anti-tubercular therapy in our hospital, based on his high leukocyte count, pleural fluid analysis, and ultrasonographic report of multiple hypoechoic areas in the liver. His symptoms continued to worsen and he subsequently developed mediastinal widening and a left lung mass. Commuted tomography (CT)-guided biopsy of the lung mass revealed a desmoplastic small-round-cell tumor. Desmoplastic small-round-cell tumor is a rare and aggressive tumor, which presents rarely as a mediastinal and lung mass. This tumor has very poor prognosis.

A series report of autoimmune hypothyroidism associated with Hashimoto's encephalopathy: an under diagnosed clinical entity with good prognosis

Hemanta K Nayak; Mrudul Kumar Daga; Rakshit Kumar; Sandeep Garg; Naresh Kumar; Pankaj Kumar Mohanty

Thyroid dysfunctions may be accompanied by numerous neurological and psychiatric disorders. The most well-known is cognitive impairment and depression in hypothyroid patients, as well as an increased risk of cerebrovascular accidents. A separate, although a rare entity, is Hashimotos encephalopathy. Unlike encephalopathy associated with other conditions, management in Hashimotos encephalopathy highly responds to steroid treatment and may be associated with normal thyroid profile at presentation. Hashimotos encephalopathy, while rare, may have been under-recognised since its clinical presentation overlaps several more common disorders, such as depression, seizures or anxiety. We present two cases of hypothyroidism with peculiar presentation. The first case has rapidly progressive neurological dysfunction, normal thyroid function at presentation, normal MRI finding and responds to steroid treatment. The second case has a subacute progressive neurological deterioration with elevated thyroid-stimulating hormone titre at presentation. Both these cases are known hypothyroidism on regular thyroxin replacement therapy with elevated anti-thyroid peroxidase antibodies. We conclude that Hashimotos encephalopathy can present with a wide spectrum of neurological illnesses in the setting of hypothyroidism. Thyroid status may vary from hypothyroid, normothyroid to even hyperthyroid. This condition usually has an abnormal electroencephalography (EEG) background and usually responds to high dose steroids.

Sweet’s syndrome in a patient with infective endocarditis: a rare clinical entity

Hemanta K Nayak; Deepak Rajkumar Vangipuram; Suresh Kumar; Premashish Kar; Ankit Gupta; Neha Kapoor; Ujjwal Sonika

Sweet’s syndrome, also known as acute febrile neutrophilic dermatosis, has been associated with malignancy, autoimmune disease and collagen vascular disease. The association of infective endocarditis and Sweet’s syndrome is rare. The authors report a case of Sweet’s syndrome in a patient with infective endocarditis. Infective endocarditis should be excluded in patients of rheumatic heart disease presenting with Sweet’s syndrome. Alternatively, Sweet’s syndrome should be considered as a differential diagnosis when a patient with infective endocarditis develops skin lesions.

Successful combined transpapillary and transmural management of a large biloma and bile duct injury: A case report and review of literature

Hemanta K Nayak; Vivek A. Saraswat; Samir Mohindra; Atul Sharma; Uday C. Ghoshal

Here, we report a patient with bile duct injury (BDI) following open cholecystectomy, who developed a very large biloma, causing duodenal and biliary obstruction, and also had a biliary stricture at the site of BDI. We successfully managed the patient by endoscopic biloma-gastrostomy with biliary stenting that resulted in resolution of the biloma and aggressive endoscopic management of the biliary stricture with stent bundles till resolution. Pertaining this case to be the one with largest biloma in the literature (approximately 6.5 L), which developed following open cholecystectomy that resulted in biliary stricture following injury to BD. We successfully managed the patient by endoscopic biloma-gastric stenting and an aggressive endoscopic management of biliary stricture.
