Study on Mycobacterium tuberculosis: the primary drug resistance pattern

The study was carried out to investigate the primary drug resistance pattern of tubercle bacilli isolated from the pulmonary tuberculosis patient attended in Shyamoli TB clinic, Dhaka. Sputum from 961 suspected tuberculous patients were randomly collected and stained by Ziehl-Neelsen (Z.N) stain. 135 were microscopically positive for Acid Fast Bacilli (AFB). Among them 30 patients were excluded from the study as they received antitubercular treatment before. So only 105 microscopically positive cases were cultured on Lowenstein-Jensen (L-J) media and 100 showed pure growth and rest 5 were contaminated with fungus. These 100 cases were studied on 4 antitubercular drugs. Out of these 100 isolates, 91 were M. tuberculosis and rest 9 in the nonchromogen group of mycobacteria other than tuberculosis (MOTT) species. Among 91 M. tuberculosis species, 89 (97.80%) to Isoniazid (INH), 73 (80.21%) to Rifampicin (RMP) and 91 (100%) to Streptomycin (SM) and Ethambutol (ETHM) were sensitive. Of the 9 MOTT species, 4 (44.44%) to SM, 7 (77.78%) to ETHM were sensitive and all (100%) were resistant to INH and RMP. Among the 100 isolates, 27 (18 M. tuberculosis and 9 MOTT) were resistant to 4 drugs either single or in combination. Of the 18 (66.67%) M. tuberculosis species, 16 (59.26%) to RMP, and 2 (7.41%) to RMP and INH were resistant. Of the 9 (33.33%) MOTT species, 4 (14.81%) to RMP and INH, 3 (11.11%) to RMP, INH and SM and 2 (7.41%) to RMP, INH, SM and ETHM were resistant.

Sezary syndrome

Sezary syndrome is a rare form of primary cutaneous T cell lymphoma. A male patient of 37 years old was reported with multiple subcutaneous swelling at different parts of the body which were asymptomatic for the last 2 years. But he had persistent generalized itching, induration in skin surface and erythema for months. The disease was diagnosed by the presence of Sezary cells in the skin biopsy, peripheral blood smears and epidermotrophism of lymphocytes. The patient was treated by CHOP (Cyclophosphamide, Doxorubicin, Vincristine and Prednisolone) therapy.

Hydatid cyst of the pancreas revealed by acute pancreatitis: A case report

INTRODUCTION AND IMPORTANCE

A hydatid cyst is a parasitic disease caused by the development of the larval form of Echinococcus granulosus (1). The liver and lungs are the most frequent locations, while pancreatic involvement is unusual (<1 %), even in countries where hydatid disease is endemic (2). We report a rare case of a hydatid cyst of the pancreas, revealed by acute pancreatitis. Through this observation and a review of the literature, we discuss the diagnostic and therapeutic challenges of this rare localization of a hydatid cyst.

CASE PRESENTATION

A 60-year-old man from rural southwestern Tunisia, with a medical history of cardiac conduction disorder such as atrioventricular block treated with a pacemaker and type II diabetes for 10 years, presented with epigastric pain and periodic episodes of vomiting for the past 2 years. The patient noticed a recent exacerbation of the pain over the last 3 months. On physical examination, there was no jaundice or fever. Mild tenderness of the entire supramesocolic region of the abdomen was revealed, and no palpable mass was evident. Biological tests showed an elevation of lipase to 5 times the normal level and an increased leukocyte count of 12,000/dL. Liver function tests were normal. The CT scan indicated pancreatitis, Balthazar grade E, with cystic formation in the tail of the pancreas extending into the dilated Wirsung duct. The echinococcal immunological test (ELISA) was positive, and tumor markers (CEA, CA 19-9) were negative. The diagnosis of a pancreatic hydatid cyst with pancreatitis was considered. The patient underwent surgery 2 months after the onset of pancreatitis. A left splenopancreatectomy was performed. Histopathological examination confirmed the presence of a hydatid cyst. Following an uneventful postoperative period, the patient was discharged on the 7th postoperative day. The patient was treated with Penicillin V (Oracillin®) 2 million IU per day for 2 years and Albendazole 800 mg per day for 2 months after surgery. At 1 year post-surgery, no hydatid recurrence was detected, and hydatid serology was negative.

CLINICAL DISCUSSION

Finally, We reported the case of a rare observation of hydatid cyst of the pancreas revealed by acute pancreatitis.

CONCLUSION

We highlighted the necessity to consider the hydatid origin when evaluating complicated cystic pancreatic tumors, especially in endemic regions.
