paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 16;9(5):1087-1095. doi: 10.12998/wjcc.v9.i5.1087.

ABSTRACT

BACKGROUND: The drug interaction between warfarin and rifampicin is widely known, but there are still some difficulties in managing the combination of the two drugs.

CASE SUMMARY: A patient with brucellosis received strict monitoring from a Chinese pharmacist team during combination of warfarin and rifampicin. The dose of warfarin was increased to 350% in 3 mo before reaching the lower international normalized ratio treatment window. No obvious adverse reaction occurred during the drug-adjustment period. This is the first case report of long-term combined use of rifampicin and warfarin in patients with brucellosis and valve replacement in China based on the Chinese lower warfarin dose and international normalized ratio range.

CONCLUSION: Anticoagulation for valve replacement in Chinese patients differs from that in other races. Establish ment of a pharmacist clinic provides vital assistance in warfarin dose adjustment.

Etomidate vs propofol in coronary heart disease patients undergoing major noncardiac surgery: A randomized clinical trial

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 26;9(6):1293-1303. doi: 10.12998/wjcc.v9.i6.1293.

ABSTRACT

BACKGROUND: The ideal depth of general anesthesia should achieve the required levels of hypnosis, analgesia, and muscle relaxation while minimizing physiologic responses to awareness. The choice of anesthetic strategy in patients with coronary heart disease (CHD) undergoing major noncardiac surgery is becoming an increasingly important issue as the population ages. This is because general anesthesia is associated with a risk of perioperative cardiac complications and death, and this risk is much higher in people with CHD.

AIM: To compare hemodynamic function and cardiovascular event rate between etomidate- and propofol-based anesthesia in patients with CHD.

METHODS: This prospective study enrolled consecutive patients (American Society of Anesthesiologists grade II/III) with stable CHD (New York Heart Association class I/II) undergoing m ajor noncardiac surgery. The patients were randomly allocated to receive either etomidate/remifentanil-based or propofol/remifentanil-based general anesthesia. Randomization was performed using a computer-generated random number table and sequentially numbered, opaque, sealed envelopes. Concealment was maintained until the patient had arrived in the operating theater, at which point the consulting anesthetist opened the envelope. All patients, data collectors, and data analyzers were blinded to the type of anesthesia used. The primary endpoints were the occurrence of cardiovascular events (bradycardia, tachycardia, hypotension, ST-T segment changes, and ventricular premature beats) during anesthesia and cardiac troponin I level at 24 h. The secondary endpoints were hemodynamic parameters, bispectral index, and use of vasopressors during anesthesia.

RESULTS: The final analysis included 40 patients in each of the propofol and etomidate groups. The incidences of bradycardia, hypo tension, ST-T segment changes, and ventricular premature beats during anesthesia were significantly higher in the propofol group than in the etomidate group (P < 0.05 for all). The incidence of tachycardia was similar between the two groups. Cardiac troponin I levels were comparable between the two groups both before the induction of anesthesia and at 24 h after surgery. When compared with the etomidate group, the propofol group had significantly lower heart rates at 3 min after the anesthetic was injected (T1) and immediately after tracheal intubation (T2), lower systolic blood pressure at T1, and lower diastolic blood pressure and mean arterial pressure at T1, T2, 3 min after tracheal intubation, and 5 min after tracheal intubation (P < 0.05 for all). Vasopressor use was significantly more in the propofol group than in the etomidate group during the induction and maintenance periods (P < 0.001).

CONCLUSION: In patients with CHD undergoing noncardiac major surgery, etomidate-based anesthesia is associated with fewer cardiovascular events and smaller hemodynamic changes than propofol-based anesthesia.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 16;9(5):1103-1110. doi: 10.12998/wjcc.v9.i5.1103.

ABSTRACT

BACKGROUND: Large intracranial dissecting aneurysm (IDA) in the anterior cerebral circulation is rare in children. There has been no consensus on the diagnosis and treatment for IDA in children.

CASE SUMMARY: We report a 3-year-old boy with a large ruptured IDA in the right middle cerebral artery (16 mm × 14 mm). The IDA was successfully managed with clipping and angioplasty. Next-generation sequencing of the blood sample followed by bioinformatics analysis suggested that the rs78977446 variant of the ADAMTS13 gene is a risk for pediatric IDA. Three years after surgery, the boy was develop-mentally normal.

CONCLUSION: Clipping and angioplasty are effective treatments for ruptured IDA in the anterior cerebral circulation. ADAMTS13 rs78977446 is a risk factor for pediatric IDA.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 26;9(6):1304-1317. doi: 10.12998/wjcc.v9.i6.1304.

ABSTRACT

BACKGROUND: Previous studies using voxel-based morphometry (VBM) revealed changes in gray matter volume (GMV) of patients with depression, but the differences between patients with bipolar disorder (BD) and unipolar depression (UD) are less known.

AIM: To analyze the whole-brain GMV data of patients with untreated UD and BD compared with healthy controls.

METHODS: Fourteen patients with BD and 20 with UD were recruited from the Mental Health Center of Shantou University between August 2014 and July 2015, and 20 non-depressive controls were recruited. After routine three-plane positioning, axial T2WI scanning was performed. The connecting line between the anterior and posterior commissures was used as the scanning baseline. The scanning range extended from the cranial apex to the foramen magnum. Categorical data are presented as frequenci es and were analyzed using the Fisher exact test.

RESULTS: There were no significant intergroup differences in gender, age, or years of education. Disease course, age at the first episode, and Hamilton depression rating scale scores were similar between patients with UD and those with BD. Compared with the non-depressive controls, patients with BD showed smaller GMVs in the right inferior temporal gyrus, left middle temporal gyrus, right middle occipital gyrus, and right superior parietal gyrus and larger GMVs in the midbrain, left superior frontal gyrus, and right cerebellum. In contrast, UD patients showed smaller GMVs than the controls in the right fusiform gyrus, left inferior occipital gyrus, left paracentral lobule, right superior and inferior temporal gyri, and the right posterior lobe of the cerebellum, and larger GMVs than the controls in the left posterior central gyrus and left middle frontal gyrus. There was no difference in GMV between patients with BD and UD.

CONCLUSION: Using VBM, the present study revealed that patients with UD and BD have different patterns of changes in GMV when compared with healthy controls.

Primary aldosteronism due to bilateral micronodular hyperplasia and concomitant subclinical Cushing's syndrome: A case report

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 16;9(5):1119-1126. doi: 10.12998/wjcc.v9.i5.1119.

ABSTRACT

BACKGROUND: Adrenal incidentaloma (AI) has been frequently encountered in the clinical setting. It has been shown that primary aldosteronism (PA) or subclinical Cushing's syndrome (SCS) are the representative causative diseases of AI. However, the coexistence of PA and SCS has been reportedly observed. Recently, we encountered a case of AI, in which PA and SCS coexisted, confirmed by histopathological examinations after a laparoscopic adrenalectomy. We believe that there were some clinical implications in the diagnosis of the present case.

CASE SUMMARY: A 58-year-old man presented with lower right abdominal pain with a blood pressure of 170/100 mmHg. A subsequent computed tomography scan revealed right ureterolithiasis, which was the cause of right abdominal pain, and right AI measuring 22 mm × 25 mm. After the disappearance of right abdomina l pain, subsequent endocrinological examinations were performed. Aldosterone-related evaluations, including adrenal venous sampling, revealed the presence of bilateral PA. In addition, several cortisol-related evaluations showed the presence of SCS on the right adrenal adenoma. A laparoscopic right adrenalectomy was then performed. The histopathological examination of the resected right adrenal revealed the presence of a cortisol-producing adenoma, while CYP11B2 immunoreactivity was absent in this adenoma. However, in the adjacent non-neoplastic adrenal, multiple CYP11B2-positive adrenocortical micronodules were detected, showing the presence of aldosterone-producing adrenocortical micronodules.

CONCLUSION: Careful clinical and pathological examination should be performed when a patient harboring AI presents with concomitant SCS and PA.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 26;9(6):1318-1328. doi: 10.12998/wjcc.v9.i6.1318.

ABSTRACT

BACKGROUND: During surgery for gastric cancer, peritoneal lavage using warm distilled water can cause temporary hemodynamic changes.

AIM: To examine the associations between changes in heart rate and single nucleotide polymorphisms (SNPs).

METHODS: This was a prospective observational study of patients with gastric cancer who underwent gastrectomy and peritoneal hypotonic lavage at the Third Affiliated Hospital of Soochow University from March 2018 to March 2019. Related SNPs were selected, and the verified exons were analyzed. Heart rate and blood pressure (BP) were measured before and after lavage. The patients were grouped as heart rate change ≥ 30% vs < 30%. Comparison and regression analyses of the selected SNPs were performed between the two groups.

RESULTS: According to the inclusion/exclusion criteria, 194 pati ents were included in the analysis. Of these patients, 138 were male, with a mean age of 65.9 ± 0.8 years, and 56 were female, with a mean age of 65.0 ± 1.3 years. Heart rate dropped by 0%-10% in 65 participants, by 10%-15% in 29, by 15%-20% in 23, by 20%-50% in 39, by 50%-100% in four, six had a cardiac arrest, and 28 had an increase in heart rate. Considering the possible impact of exonic SNPs on the phenotypes, TEP1 (rs938886), TEP1 (rs1713449), and RECQL5 (rs820196) were analyzed. The haplotype analysis suggested that the haplotypes CTT [odds ratio (OR) = 2.018, 95% confidence interval (CI): 1.012-4.025, P = 0.0430] and GCC (OR = 2.293, 95%CI: 1.174-4.477, P = 0.0131) of TEP1 (rs938886), TEP1 (rs1713449), and RECQL5 (rs820196) increased the risk of a drop in heart rate > 30%.

CONCLUSION: The TEP1 (rs938886), TEP1 (rs1713449), and RECQL5 (rs820196) SNPs were associated with changes in heart rate ≥ 30% during intraperitoneal lavage using distilled water after gastrectomy for gastric cancer.

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 16;9(5):1132-1138. doi: 10.12998/wjcc.v9.i5.1132.

ABSTRACT

BACKGROUND: Although the imaging features of coronavirus disease 2019 (COVID-19) are starting to be well determined, what actually occurs within the bronchi is poorly known. Here, we report the processes and findings of bronchoscopy in a patient with COVID-19 accompanied by respiratory failure.

CASE SUMMARY: A 65-year-old male patient was admitted to the Hainan General Hospital on February 3, 2020 for fever and shortness of breath for 13 d that worsened for the last 2 d. The severe acute respiratory syndrome coronavirus 2 nucleic acid test was positive. Routine blood examination on February 28 showed a white blood cell count of 11.02 × 109/L, 86.9% of neutrophils, 6.4% of lymphocytes, absolute lymphocyte count of 0.71 × 109/L, procalcitonin of 2.260 ng/mL, and C-reactive protein of 142.61 mg/L. Oxygen saturation was 46% at baseline and turned to 94% after ventilation. The patient underwent video bronchoscopy. The tracheal cartilage ring was clear, and no deformity was found in the lumen. The trachea and bilateral bronchi were patent, while the mucosa was with slight hyperemia; no neoplasm or ulcer was found. Moderate amounts of white gelatinous secretions were found in the dorsal segment of the left inferior lobe, and the bronchial lumen was patent after sputum aspiration. The right inferior lobe was found with hyperemia and mucosal erosion, with white gelatinous secretion attachment. The patient's condition did not improve after the application of therapeutic bronchoscopy.

CONCLUSION: For patients with COVID-19 and respiratory failure, bronchoscopy can be performed under mechanical ventilation to clarify the airway conditions. Protection should be worn during the process. Considering the risk of infection, it is not necessary to perform bronchoscopy in the mild to moderate COVID-19 patients .

Efficacy of afatinib in a patient with rare EGFR (G724S/R776H) mutations and amplification in lung adenocarcinoma: A case report

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 26;9(6):1329-1335. doi: 10.12998/wjcc.v9.i6.1329.

ABSTRACT

BACKGROUND: The most common EGFR mutations are in-frame deletions in exon 19 and point mutations in exon 21. Cases with classical EGFR mutations show a good response to EGFR tyrosine kinase inhibitors (TKIs), the standard first-line treatment. With the development of next generation sequencing, some uncommon genomic mutations have been detected. However, the effect of TKIs on such uncommon EGFR mutations remains unclear.

CASE SUMMARY: Here, we report a case of rare EGFR co-mutation in non-small cell lung cancer and the efficacy of afatinib on this EGFR co-mutation. A 64-year-old woman was diagnosed with thoracolumbar and bilateral local rib bone metastases, bilateral pulmonary nodules, and pericardial and left pleural effusion. The pathological diagnosis was lung adenocarcinoma. To seek potential therapeutic regimens, rare co-mutation comprising rare EGFR G724S/R776H mutations and amplification were identified. The patient experienced a significant clinical response with a progression-free survival of 17 mo.

CONCLUSION: A case of non-small cell lung cancer with rare EGFR G724S/R776H mutations and EGFR amplification responds well to TKI treatment.

Successful bailout stenting strategy against rare spontaneous retrograde dissection of partially absorbed magnesium-based resorbable scaffold: A case report

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 16;9(5):1148-1155. doi: 10.12998/wjcc.v9.i5.1148.

ABSTRACT

BACKGROUND: In the development of coronary stent technology, bioresorbable scaffolds are promising milestones in improving the clinical treatment of coronary artery disease. The "leave nothing behind" motto is the premise of the fourth revolution in percutaneous coronary intervention (PCI). Studies proving the safety and efficacy of the magnesium-based resorbable scaffolds (MgBRSs) include the BIOSOLVE-I and BIOSOLVE-II trials and the latest BIOSOLVE-IV registry. However, spontaneous retrograde dissection of a partially absorbed MgBRS may still occur, albeit rarely.

CASE SUMMARY: We describe an unusual case of coronary artery disease in a patient who had undergone a successful PCI 8 mo earlier, where an MgBRS was implanted into the left anterior descending artery (LAD) and left circumflex artery with drug-coated balloons for a ramus intermediu s branch stenosis to achieve the "leave nothing behind" therapeutic intention and was currently presenting with a gradual worsening of chest tightness. The distal edge vascular response, during subsequent attempts with balloon angioplasty was performed smoothly. However, spontaneous retrograde dissection of a partially absorbed MgBRS in the LAD ensued. Successful bailout stenting was performed with revascularization of the entry and exit sites created by spontaneous dissection and complete sealing of the intramural hematoma. The patient recovered well and was discharged after 2 d of intervention. When followed up in August 2020 (7 mo later), the patient showed uneventful recovery.

CONCLUSION: Spontaneous retrograde dissection of a partially absorbed MgBRS was successfully treated using bailout sirolimus-eluting coronary stent strategy.

Esophageal superficial adenosquamous carcinoma resected by endoscopic submucosal dissection: A rare case report

paythelady.612 shared this article with you from Inoreader

World J Clin Cases. 2021 Feb 26;9(6):1336-1342. doi: 10.12998/wjcc.v9.i6.1336.

ABSTRACT

BACKGROUND: Adenosquamous carcinoma (ASC), which is comprised of squamous cell carcinoma (SCC) and adenocarcinoma elements, is a rare histological type of esophageal carcinoma. Few reports have focused on the endoscopic findings and the effectiveness of the endoscopic treatment of early ASC.

CASE SUMMARY: A 77-year-old man underwent esophagogastroduodenoscopy for heartburn. A flat lesion with an uneven and slightly elevated central portion was found in the distal esophagus. Magnifying endoscopy with narrow-band imaging showed a well-demarcated brownish area with dendritically branched abnormal vessels and highly irregular intrapapillary capillary loops. A histopathological diagnosis of SCC was obtained by endoscopic biopsy. Endoscopic ultrasonography revealed a hypoechoic mass confined to the mucosa layer. The lesion was suspected to be SCC wi th invasion into the muscularis mucosa. The lesion was resected en bloc by endoscopic submucosal dissection and histologically diagnosed as esophageal ASC limited within the muscularis mucosa, which was completely resected without lymphovascular or neural invasion. The SCC element was the pre-dominant element. The adenocarcinoma element formed ductal and nested structures distributed in a focal pattern. The patient underwent only endoscopic submucosal dissection and has been under annual endoscopic and radiographic surveillance for 3 years without recurrence.

CONCLUSION: For early ASC confined within the mucosal layer, complete endoscopic resection might also be a curative treatment.
