RESUMEN
Pneumorrhachis is a rare entity, where air pockets are found in the spinal canal and the etiology can be categorized into traumatic and non-traumatic, the latter further categorized into spontaneous, iatrogenic, and associated with infections. Infective causes are often associated with gas-forming organisms and are associated with significant morbidity and mortality. Often the diagnosis is not suspected until imaging is done. We report the case of a 57-year-old man who presented with fever, backache, lower leg weakness, and dysuria. A computed tomography scan for evaluation of intra-abdominal sepsis incidentally showed pneumorrhachis affecting the thoracic and lumbar levels, gas-forming paraspinal abscess, prostate abscess, liver cirrhosis, and sigmoid colon carcinoma. Blood culture isolated Klebsiella pneumoniae. The patient recovered after six weeks of intravenous antibiotics followed later by sigmoid colectomy and chemotherapy. A literature review identified 63 cases of pneumorrhachis associated with infections and can be categorized into infections with spontaneous pneumorrhachis (predominantly respiratory tract infections), infections with pneumorrhachis (predominantly with emphysematous infections), and iatrogenic with infections and pneumorrhachis (predominantly postspinal interventions). Infections with pneumorrhachis occurred in older age groups and were associated with higher mortality compared to the other two categories.
RESUMEN
BACKGROUND: Multidrug-resistant Helicobacter pylori strains are emerging in Southeast Asia. This study evaluates the region's real-world practice in H. pylori management. MATERIALS AND METHODS: Physicians who managed H. pylori eradication in daily practice across 10 Southeast Asian countries were invited to participate in an online questionnaire, which included questions about the local availability of antimicrobial susceptibility tests (ASTs) and their preferred eradication regimens in real-world practice. An empiric regimen was considered inappropriate if it did not follow the local guidelines/consensus, particularly if it contained antibiotics with a high reported resistance rate or was recommended not to be empirically used worldwide. RESULTS: There were 564 valid responses, including 314 (55.7%) from gastroenterologists (GIs) and 250 (44.3%) from non-GI physicians. ASTs were unavailable in 41.7%. In countries with low and intermediate clarithromycin resistance, the most common first-line regimen was PAC (proton pump inhibitor [PPI], amoxicillin, clarithromycin) (72.7% and 73.2%, respectively). Regarding second-line therapy, the most common regimen was bismuth-based quadruple therapy, PBMT (PPI, bismuth, metronidazole, tetracycline) (50.0% and 59.8%, respectively), if other regimens were used as first-line treatment. Concomitant therapy (PPI, amoxicillin, clarithromycin, metronidazole) (30.5% and 25.9%, respectively) and PAL (PPI, amoxicillin, levofloxacin) (22.7% and 27.7%, respectively) were favored if PBMT had been used as first-line treatment. In countries with high clarithromycin resistance, the most common first-line regimen was PBMT, but the utilization rate was only 57.7%. Alarmingly, PAC was prescribed in 27.8% of patients, ranking as the second most common regimen, and its prescription rate was higher in non-GI physicians than GI physicians (40.1% vs. 16.2%, p < 0.001). CONCLUSIONS: Choosing inappropriate regimens containing antibiotics with high resistance rates is not uncommon in Southeast Asia, especially among non-GI physicians. In countries with high clarithromycin resistance, the PBMT regimen is underutilized.
