After eight additional cycles of chemotherapy consisting of temozolomide and irinotecan, which led to stable disease, the patient underwent preparative conditioning with fludarabine (150 mg\/m2), melphalan (140 mg\/m2), and 12 Gy of TBI for subsequent allogeneic CBT. The patient received tacrolimus and a short-term course of methotrexate for GVHD prophylaxis. The patient underwent engraftment on day 17. He then developed grade 3 GVHD, which was managed by increasing the prednisolone dose and was later discharged on day 85. The patient also received proton beam therapy (39.6 Gy) from days 121 to 150 post-transplantation for a right supra-mediastinum tumor with residual I123-MIBG accumulation in the right adrenal gland.\n\nThe patient remained healthy with no evidence of GVHD until presentation at our hospital with a productive cough on day 159. As his older brother displayed similar cold symptoms, a rapid antigen test for RSV was performed, which revealed a positive result. His respiratory symptoms gradually worsened, and he revisited our hospital on day 194 with dyspnea and intercostal retractions. Upon admission, he was given 0.7-1.0 mg\/kg of prednisolone, which failed to improve his respiratory condition. Chest computed tomography on day 231 revealed infiltration, ground-glass opacity, and septal thickening in the bilateral lung fields along with right pleural effusion. Echocardiography showed an elevated tricuspid regurgitation peak velocity of 4.1 m\/s and an interventricular septum close to the isobaric, indicating the presence of PH. In addition, pericardial effusion was detected. On day 231, the patient was transferred to the pediatric intensive care unit, where mechanical ventilation and inhaled nitric oxide (NO) were initiated. Thoracoscopic lung biopsy on day 244 revealed diffuse intra-alveolar hemorrhage and edema on hematoxylin-eosin (HE)-stained samples. Elastica van Gieson staining revealed diffuse obstructive lesions due to fibrocellular components with plump endothelial cells in the pre-septal pulmonary veins and venules. While pulmonary muscular arteries and arterioles showed mild medial hypertrophy and focal intimal thickening (Heath-Edwards Grade 2), severe stenosis with concentric intimal fibrosis or plexiform lesions was present. Based on these results, the patient was diagnosed with PVOD with mild pulmonary arterial\/arteriolar lesions. Of note, HE staining also revealed enlarged type II pneumocytes with multinucleated and giant cell-like features, indicating the presence of prior lung injury that was likely attributable to his preceding viral infection.","diff_label_texts":"A 4-year-old boy with stage IV neuroblastoma underwent four cycles of chemotherapy including high-dose busulfan and melphalan, followed by autologous peripheral blood stem cell transplantation with autologous bone marrow supplementation.

Initially, four days ago, canker sores started in the oral cavity, then appeared on the lips two days later. The patient tried to self-medicate by applying petroleum jelly which he used to relieve his symptoms, but it did not improve. The patient replaced the drug with triamcinolone acetonide 0.1% in orabase ointment purchased at the pharmacy and applied it once a day. Canker sores were getting better but did not cure.\n\nThe patient had history a of fever for about a week before the canker sores appeared and there were no lesions on other parts of the body. He stated that the workload was quite heavy and he had not consumed a balanced nutritional diet for about one and a half months. He had no medical history, history of food allergies, or history of taking medication. He had no history of alcohol consumption or smoking, but he had a frequent habit of licking his lips. He also had a history of chickenpox when he was a child.\n\nThe patient had no fever with all vital signs within normal limits on general examination. Extra-oral examination showed no abnormalities in the lymph nodes. There were serosanguineous crusts that felt painful and bleed easily on the lips. Intra-oral examination revealed erythematous lesions, irregular in shape, and had diffuse borders, accompanied by pain in the upper and lower labial mucosa. Hyperkeratotic white plaque that could not be scraped off, irregular in shape, has diffuse borders, without pain in the region of tooth 38 left buccal mucosa. Yellowish-white plaques were seen on 1\/3 of the posterior surface of the dorsal tongue, which could be scraped off without leaving an erythematous area, and there were indentations in the form of dental impressions without pain on the lateral right and left sides of the tongue. A painless hard nodule about 2\u00d71 x 0.5 cm in size was seen in the midline of the hard palate. Several teeth were found in caries, radix, and edentulous conditions in all regions. The oral hygiene was poor.\n\nExamination of psychological conditions was evaluated using the DASS-21 questionnaire and showed normal depression level (score 0), normal anxiety level (score 6), and normal stress level (score 6).

The differential diagnosis of suspected HAEM lesions on the lips was exfoliative cheilitis. However, exfoliative cheilitis did not have herpes virus involvement. The patient was indicated for serological testing (IgG anti-HSV-1) to confirm the diagnosis. Oral health-related quality of life was measured, and the results of the OHIP-14 examination at the first visit were 35 (moderate OHRQol).\n\nThe non-pharmacological therapy included instruction to maintain oral hygiene by brushing the teeth and tongue using a soft-bristled toothbrush two times a day and using non-detergent toothpaste. Education was given such as increasing the intake of water by at least two liters per day, consuming a balanced nutritional diet, avoiding acidic, spicy, hard, and monosodium glutamate-containing foods, and stopping the bad habit of licking and peeling the skin of the lips. The pharmacological therapy included topical and systemic medications. The topical medications included instructions to compress the lips with gauze moistened with 0.9% NaCl solution at least three times a day and to apply a thin layer of triamcinolone acetonide 0.1% in orabase to the lips three times a day. The systemic medications included instruction to take a multivitamin once a day.\n\nThe progress of improvement was visible in the first follow-up, two days after the initial visit. The pain in the lips was reduced, but the canker sores have not healed. Extra-oral examination revealed serosanguinous crusts on the lips which were still painful and bled easily.

He returned to work without fever after resting for two days, but lost consciousness while working outdoors in an ambient temperature of 35\u00b0C for five hours. Upon admission to the local hospital\u2019s emergency department, his core temperature (Tc) was recorded as 40\u00b0C. The patient presented with persistent coma, dyspnea and gastrointestinal hemorrhage. No underlying diseases and relative family history was noted. Based on the characteristic presentation of hyperpyrexia, coma and multiple organ damage, a diagnosis of HS was established. He was admitted to emergency intensive care unit (ICU) of the local hospital and then received mechanical ventilation. The test results indicated the presence of pulmonary infection, hepatic and renal dysfunction, myocardial ischemia and coagulation disorders. The patient received initial management including rehydration (intravenously infused Lactated Ringer\u2019s solution and normal saline at a rate of 2.5mL\/kg\u2219h), intravenous administration of Piperacillin Sodium and Tazobactam Sodium, vasoactive medications for blood pressure support, continuous mechanical ventilation, and continuous renal replacement therapy (CRRT) to manage subsequent anuria. The patient received plasma transfusion and was administered Tranexamic acid on day 5. The worsening of his condition led to his admission to the medical ICU of our hospital 7 days after HS.\n\nFollowing admission, Reverse-transcription polymerase chain reaction (RT-PCR) testing of a nasopharyngeal swab yielded positive results for SARS-CoV-2. The patient was diagnosed with HS and severe COVID-19 based on China\u2019s COVID-19 Diagnosis and Treatment Program (trial version 10): 1. real-time fluorescent RT-PCR detection of SARS-CoV-2 nucleic acid is positive; 2. respiratory failure and requires mechanical ventilation; 3. shock; 4. combined with multiple organ failure requiring intensive care. The patient had no contact with COVID-19 diagnosed patients or healthcare workers in the hospital, indicating community-acquired infection. The physical examination showed a Glasgow Coma Scale (GCS) score of 3\/15, with scores of 1 for eye-opening, verbal response, and motor response. Additionally, the pupils were symmetrical and non-reactive. The heart rate was recorded at 106 bpm and blood pressure was maintained at 126\/77 mmHg by continuously infusing norepinephrine at a rate of 0.4 ug\/kg\u00b7min. The laboratory test results indicated a severe infection, along with anemia, thrombocytopenia, disseminated intravascular coagulation (DIC), as well as acute liver and kidney injury. The white blood cell count (WBC) decreased from 3.55\u00d7109\/L to 3.13\u00d7109\/L, lymphocytes significantly decreased from 0.25\u00d7109\/L to 0.1\u00d7109\/L, and neutrophil percentage (N%) increased to 85.3%. The Procalcitonin level measured 2.81 ng\/mL and C-reactive protein (CRP) level was 32.6 mg\/L. Sputum culture testing yielded Stenotrophomonas Maltophilia and Candida lipolytica. The central venous catheter culture test detected Staphylococcus epidermidis, but the continuous blood culture test yielded no positive results. The Computed Tomography (CT) scan revealed bilateral frontal subdural effusion, consolidation and atelectasis in the lower lungs, inflammation in the right upper lobe, bilateral pleural effusion, and a small amount of abdominal fluid.\n\nThe patient received synchronized intermittent mandatory ventilation with a positive end expiratory pressure of 5 mmH2O and an oxygen concentration of 80% and continuous administration of norepinephrine and pituitrin to sustain normal blood pressure. Polyene phosphatidylcholine, adenosylmethionine budisulfonate, ulinastatin, and hemofiltration have been employed for the management of hepatic and renal dysfunction. The antibiotic was substituted with Meropenem and Thymalfasin was administered for 20 days to augment immune function. Mannitol was used to alleviate intracranial pressure for 3 days. To improve coagulation dysfunction, the patient received plasma and cryoprecipitate transfusions, continuous intravenous infusion of heparin sodium at 6000u\/day and CRRT with sodium citrate for anticoagulant (8g\/day) on day 7. Platelet transfusion was administered after 9 days of HS. His Tc fluctuated between 36 \u00b0C and 38.5 \u00b0C. CRRT was administered without anticoagulant on day 8. The patient had gastrointestinal hemorrhage and fever after 9 days of HS, but electronic gastroenteroscopy showed no signs of active bleeding. He underwent red blood cell suspension transfusion, hemostasis treatment and gastric acid suppression. Teicoplanin was added due to the presence of Methicillin-resistant Staphylococcus aureus isolated from sputum culture. The patient regained consciousness on day 13 with a GCS score of 14\/15 and presented with a moderate fever. Gastrointestinal hemorrhage was not observed. Mechanical ventilation was discontinued and the tracheal tube was removed. But the creatinine levels increased following the suspension of CRRT on day 12.\n\nOn day 17, he developed sudden dyspnea with desaturation (oxygen saturation <85%) followed by a high fever (Tc: 39.3\u00b0C), necessitating reintubation and mechanical ventilation. Bronchoscopy revealed less sputum in both lungs and subbranches. He experienced a recurrence of coma, with a GCS score of 3\/15. WBC increased to 14.94\u00d7109\/L and NEU increased to 13.77\u00d7109\/L. The levels of serum total bilirubin rose to 235.2 \u00b5mol\/L, while creatinine increased to 441\u00b5mol\/L. The brain CT scan revealed an ischemic stroke in the right frontal lobe and a hemorrhagic infarction in the right occipital lobe. The patient underwent cooling therapy using CRRT with ice-cold replacement fluid, along with persistent administration of Meropenem and Teicoplanin for anti-infection treatment. Carpofungin was added on day 18 due to the observed elevation in serum levels of Aspergillus galactomannan, Aspergillus IgG antibody, and Candida mannan. The RT-PCR testing for SARS-CoV-2 returned negative results.\n\nThe patient\u2019s fever and infection improved on day 20, but he subsequently developed cerebral hemorrhage and hernia with bilateral dilated pupils. The dehydration therapy was used to reduce intracranial pressure, as surgery was refused by his family. On day 22, indicators of infection, levels of aspartate aminotransferase and creatinine increased again. Carbapenem-resistant Acinetobacter baumannii and A. fumigatus were cultured in the bronchoalveolar lavage fluid. The combination of Meropenem, Teicoplanin, and Carpofungine was administered for anti-infective therapy. The patient\u2019s condition progressively worsened over the next 7 days, ultimately resulting in his demise on day 29.

There was no fever, blood \/ mucus in the stool, or respiratory symptoms (rhinorrhea, wheezing, coughing). She had no history of alcohol\/tobacco use or traditional herbal medicines. Six weeks before admission, she was diagnosed with an intestinal infection in a local clinic after a complete blood count (CBC) revealed leukocytosis and significant eosinophilia (25.61 G\/L, 77.8% eosinophils). She received antibiotics and mebendazole without relief of symptoms. At presentation, the patient was alerted and oriented with stable vitals (BP 110\/70 mmHg, T 37\u00b0C, HR 88 bpm, RR 18 bpm). She had a BMI of 16.6 kg\/m\u00b2 and sarcopenia, but no skin rash, lymphadenopathy, or edema. The abdominal exam showed tenderness in the epigastric and umbilical regions without guarding.

Other parameters were normal, including aminotransferase, blood urea nitrogen, serum creatinine, complement C3, complement C4, vitamin B12, serum cortisol, and NT-proBNP. ECG and echocardiogram were normal. Chest CT scans showed mild fibrosis and bronchiectasis. Sputum AFB smears and bronchoscopy were negative. The cytology of the bronchoalveolar lavage fluid showed 35% neutrophils, no eosinophils. Spirometry indicated severe obstruction with bronchodilator response. The fractional exhaled nitric oxide (FeNO) level was 15 ppb. Stool samples were tested positive for leukocytes, with no signs of ova or parasites. Serology tests were positive for toxocariasis (positive IgG of Toxocara canis at 54.2 NovaTec-Units) but negative for Strongyloides stercoralis, Fasciola sp., Toxoplasma gondii, Trichinella spiralis, Ancylostoma sp., Angiostrongylus cantonensis, Ascaris lumbricoides, Clonorchis sinensis, Paragonimus sp., Gnathostoma sp., Entamoeba histolytica, cysticercosis, filariasis, and HIV.

A year prior, the patient had presented with similar symptoms and was diagnosed with myocarditis at a local hospital based on clinical findings at that time. During that hospitalization, she was also diagnosed with hypertension and prescribed antihypertensive medications. However, after discharge, the patient did not adhere to the prescribed antihypertensive therapy and did not regularly monitor her blood pressure. Additionally, it is notable that her father had a history of sudden, unexplained death.\n\nTo investigate the underlying etiology of the patient\u2019s symptoms, a chest computed tomography (CT) scan was performed. Incidentally, this scan revealed a left adrenal mass with soft tissue density, measuring 43 mm \u00d7 36 mm. No pathological findings were observed in the head and chest CT scans. The electrocardiogram demonstrated sinus tachycardia with a shortened PR interval and tall, peaked P-waves in leads II, III, and aVF. Transthoracic echocardiography did not reveal any significant abnormalities.\n\nOn the second day of admission, the patient exhibited rising levels of brain natriuretic peptide (BNP) and Troponin I (TnI). The cardiologist provisionally diagnosed the patient with myocarditis of uncertain etiology, based on clinical presentation, elevated cardiac biomarkers (BNP and TnI), and supportive electrocardiogram findings. Treatment was initiated with methylprednisolone (0.25 g daily) to address potential myocardial inflammation due to suspected myocarditis. Furosemide (20 mg every 12 hours) and spironolactone (20 mg every 12 hours) were administered as diuretics to manage fluid retention and reduce cardiac workload. Perindopril amlodipine (10 mg: 5 mg daily) was prescribed as an angiotensin-converting enzyme inhibitor and calcium channel blocker combination to control blood pressure and reduce afterload. Metoprolol tartrate (25 mg every 12 hours) was used to manage heart rate and decrease myocardial oxygen demand, while esmolol (0.2 g\/hour intravenous infusion), a short-acting beta-blocker, was administered for additional acute heart rate control due to sinus tachycardia. Due to concerns about a potential infection, moxifloxacin was added as empiric antibiotic therapy.\n\nGiven the patient\u2019s presentation with an adrenal mass and hypertension, the endocrinologist recommended an evaluation of the aldosterone-to-renin ratio, plasma cortisol, plasma catecholamines, and 24-hour urinary catecholamines along with their metabolites. In the recumbent position, plasma and urinary catecholamine levels were markedly elevated (Table 1), including plasma dopamine at 524.5 pmol\/L, norepinephrine at 83975 pmol\/L, and epinephrine at 10579.3 pmol\/L. Additionally, the 24-hour urinary levels showed free adrenaline at 4368.89 nmol\/24 hours, free norepinephrine exceeding 12697.60 nmol\/24 hours, normetanephrine at 8312 nmol\/24 hours, metanephrines at 4078 nmol\/24 hours, and vanillylmandelic acid at 58.1 mg\/24 hours. These findings supported a clinical diagnosis of pheochromocytoma. On the fifth day post-admission, glucocorticoid therapy was discontinued, and perindopril amlodipine was substituted with terazosin for more targeted blood pressure management.\n\nAn enhanced abdominal CT scan further confirmed a left adrenal mass, highly suggestive of pheochromocytoma. Additionally, after obtaining informed consent, whole-exome sequencing was performed, revealing a heterozygous missense mutation, c.1900T > C: p. Cys634Arg, in the RET gene, leading to a substitution of cysteine with arginine at codon 634. This mutation raised suspicion for multiple endocrine neoplasia syndrome, prompting further evaluation of the thyroid and parathyroid glands. Thyroid color Doppler ultrasound identified a hypoechoic mass measuring 6 mm \u00d7 4 mm in the left thyroid lobe, and a mild elevation in calcitonin levels was noted. No additional significant abnormalities were detected.\n\nAs the patient\u2019s condition gradually improved, plasma cortisol and ACTH levels returned to normal. The patient was subsequently discharged with a prescription for metoprolol tartrate (100 mg every 12 hours) and ivabradine hydrochloride (5 mg every 12 hours) for home management. Three months later, after achieving stable clinical status, the patient underwent resection of the left adrenal tumor, which measured 50 mm \u00d7 40 mm \u00d7 30 mm. Immunohistochemical analysis confirmed positive staining for Vim, CD56, Syn, CgA, and NSE, with S-100 positive in Sertoli cells, while CKpan, CD10, MART-1\/Melan-A, and Melan-A were negative. The Ki67 index was 1%, leading to a definitive diagnosis of adrenal pheochromocytoma. The patient was discharged without further medications and has since been regularly followed up postoperatively without recurrence of symptoms. Over a 15-month postoperative follow-up, the patient exhibited persistently mild hypercalcitoninemia with stable thyroid nodule size, while PTH and serum calcium levels showed a progressive increase (Table 2).

She consulted due to a 4 week diarrhea with blood streaks (5 to 10 episodes a day). A week after the onset of the diarrhea she consulted the emergency department, where rotavirus (+) was detected, with low inflammatory parameters, negative coproculture and normal abdominal ultrasound. She was hospitalized for 3 days to manage dehydration and was discharged without bleeding, with persistence of semi-liquid stools. 10 days after discharge she presented diarrhea with blood streaks, associated with low intake and weight loss of 1 kg reported by parents. They consulted a pediatric gastroenterologist who requested a polymerase chain reaction (PCR) panel of gastrointestinal pathogens and PCR of Clostridium difficile (which were negative) and indicated hospitalization for study.\n\nOn direct questioning, the parents reported no fever, abdominal pain, vomiting, respiratory or urinary symptoms, arthralgia, or new skin lesions. They did not own pets, and there was no history of travel or recent dietary changes.\n\nThe patient was diagnosed with confirmed NF1 at 8 months of age by genetic testing with the heterozygous pathogenic variant c.5606_5627del (p.Gly1869Valfs*28). She has skin involvement (caf\u00e9 con leche spots) and bone involvement. At 18 months she required ankle arthrodesis for tibial curvature. She has no family history of NF1 or inflammatory bowel disease.\n\nOn physical examination, the abdomen was soft and indistinct, with increased air-bubble murmurs, without masses or visceral enlargement. The perianal examination was normal. There were multiple brown-coffee stains on the lower extremities and back. General examinations were performed, including a blood count with moderate microcytic-hypochromic anaemia (Hb 9.6 g\/dL), leukocytosis with left shift (leukocytes 13,900), and discretely elevated inflammatory parameters (CRP 1.37 mg\/dL, normal value up to 0.5 mg\/dL).\n\nA colonoscopy was performed, the rectum, sigmoid and various segments of the colon were examined up to the cecum, visualizing the ileocecal valve and the appendicular orifice. The last few centimeters of the distal ileum were also inspected. The mucosa from the anal margin to the cecum was observed to be erythematous, with loss of vascular transparency, unlike the cecal mucosa, which appeared normal. No lesions were identified in the anal canal or cecum.\n\nBiopsies of the small intestine (ileon) and large intestine were taken. Microscopic examination showed mucosa of ileal type with preserved villous architecture and adequate epithelial differentiation, with a non-inflamed lamina propria. The mucosa of the large intestine had a mild distortion of architecture and adequate epithelial differentiation, a swollen lamina propria with a mild mixed inflammatory infiltrate and hyperplasia of lymphoid follicles. Isolated foci of microabscesses were recognized. The biopsy was consistent with mild colitis, with signs suggesting chronicity.\n\nIn addition, a PCR study for cytomegalovirus (CMV) was requested in a colon biopsy, which was positive.\n\nGiven a positive PCR for CMV, CMV IgG and IgM and CMV viral load in blood were requested, resulting in a positive IgG, negative IgM, and CMV viral load of 79.7 IU\/ml. Further laboratory studies included PCR for gastrointestinal pathogens and PCR for Clostridium difficile in stool, both of which were negative. In the colon biopsy, Gram stain microbiological studies were requested, which showed +++ leukocytes without bacteria; biopsy culture showed S. gallolyticus\/equinus complex in very low amount (interpreted as bacterial flora); acridine orange, Ziehl-Neelsen, Koch culture, and ADV PCR were negative.\n\nEndoscopy and histology suggestive of UC was reported in the context of a patient with moderate symptoms (PUCAI 50) who was started on Mesalazine (70 mg\/kg\/day three times daily) and a request for a faecal calprotectin was made which was greater than 600 ug\/g.\n\nThe immunology team evaluated the patient for suspected immunodeficiency. The parents did not report a history of infections, they reported that they were vaccinated, that they had good weight gain, no family history of immunodeficiencies, auto-immunity or early deaths. A study with lymphocyte subpopulations (normal), immunoglobulins (normal), HIV (negative), memory T lymphocytes (with alterations expected in the context of CMV viremia) and lymphoproliferation test (normal) was requested. In addition, a genetic panel of primary immunodeficiencies (Invitae) was performed, which contains 429 genes, of which 68 make up the panel of monogenic inflammatory intestinal disease. 7 variants of uncertain significance were obtained, none included in the panel of monogenic IBD.\n\nGanciclovir was initiated intravenous for CMV infection and continued for 15 days. The last PCR CMV control prior to discharge reported undetectable load.\n\nThe patient improved during the hospital stay with decreased frequency of stools and increased consistency, no rectal bleeding, no nocturnal stools and no abdominal pain, with PUCAI 0 at discharge.\n\nTwo months later, he presented with a reactivation of IBD with bloody diarrhea (PUCAI 35). A blood count was performed (normal), a panel of gastrointestinal pathogens was performed (\u2013), PCR for Clostridium difficile was performed (+), and CMV load was undetectable. He was treated with oral metronidazole. However, he persisted with diarrhea with blood streaks, so he was hospitalized again.\n\nA colonoscopy was performed, where erythematous mucous was observed in a diffuse form from the rectum to the cecum, with nodularity and loss of vascular transparency in the submucosa, greater in the left and transverse colon segments. No focal lesions were observed. The mucosa of the ileum and anal canal were observed without lesions.\n\nBiopsy of the terminal ileum, right colon and left colon was performed. Microscopic examination of the ileal-type mucosa showed preserved villous architecture and adequate epithelial differentiation. The lamina propria showed no signs of inflammation. There were no aphthous erosions or granulomas. The mucosa of the large intestine showed mild distortion of architecture and epithelial dedifferentiation. The lamina propria was expanded by mixed inflammatory infiltrate, transmucosal distribution. Foci of cryptitis and cryptitic microabscesses and hyperplasia of reactive lymphoid follicles were recognized. No granulomas, viral or parasitic cytopathic changes were observed. All fragments of the left colon sample presented a similar histopathological picture.\n\nShe was given oral treatment with Vancomycin and Prednisone (1 mg\/kg\/day) with a good response and a favorable evolution.

Her medical history included only hypertension and dyslipidaemia. When she presented to the emergency room, her vital signs indicated shock (heart rate: 100 beats\/min, blood pressure: 79\/56\u2009mmHg), and blood tests revealed anaemia (haemoglobin: 9.6\u2009g\/dL), which suggested upper gastrointestinal bleeding.\n\nNon-contrast-enhanced CT was performed immediately because of renal dysfunction. CT revealed that the third part of the duodenum flexed steeply on the right side of the aorta and ran caudally, without crossing anterior to the aorta. The jejunum was located on the patient\u2019s right side. The second part of the duodenum and the stomach were dilated, and there were high-density gastric contents that were considered to indicate a haematoma.\n\nUpper gastrointestinal endoscopy was performed following the CT examination, which revealed a mucosal laceration at the gastric cardia. Bleeding from lacerations of the cardia of the stomach as a result of forceful vomiting was first reported by Mallory and Weiss in 1929.1 In our case, the third part of the duodenum flexed steeply, and the lumen was narrowed, which caused an obstruction. As a result, repeat vomiting was considered to have caused Mallory\u2013Weiss syndrome.\n\nOn the basis of the CT findings showing that the duodenal-jejunal junction was located in the right hemi-abdomen, intestinal malrotation was suspected.2 However, 7\u2009days later, when CT was repeated, spontaneous resolution of the malpositioned jejunum was seen. The patient was then discharged from the hospital. However,\u2009months later, she was rushed to the emergency room for repeat haematemesis. Dynamic CT was performed before upper gastrointestinal endoscopy, on admission, and revealed contrast extravasation in the dilated stomach. Additionally, the third part of the duodenum was flexed on the right side of the aorta, and the duodenal-jejunal junction and jejunum were again located in the right hemi-abdomen. Upper gastrointestinal endoscopy revealed a laceration at the gastric cardia, as in the previous endoscopy, which was considered Mallory\u2013Weiss syndrome.\n\nTwo months after the second episode of haematemesis, the patient presented to the emergency room with nausea. Non-contrast-enhanced CT revealed no abnormalities in the duodenal positioning, but there was oedematous wall thickening in the second part of the duodenum. If we had not had previous CT images, we would have suspected duodenitis, but on the basis of all of the CT findings, we suspected the possibility of an underlying condition after the right-sided deviation of the small intestine had resolved spontaneously.\n\nIn summary, CT was performed 4 times over 5\u2009months. The third and fourth parts of the duodenum and the jejunum deviated repeatedly, but this resolved spontaneously, which is not indicative of intestinal malrotation. Therefore, we diagnosed dysplasia of the ligament of Treitz.\n\nClinical outcomes\nThe patient underwent laparotomy, which revealed no abnormalities in the relative position of the duodenum to the jejunum. Additionally, the jejunum was located on the patient\u2019s left side, and there was no intestinal malrotation. The ligament of Treitz was formed; however, its fixation in the upper jejunum was incomplete as it was attached only to the duodenum. The duodenal-jejunal junction was not fixed to the retroperitoneum, and the jejunum folded easily with the ligament of Treitz as a fulcrum. Surgically, the upper jejunum was fixed with 4 sutures to the retroperitoneum on the patient\u2019s left side.

Upper GI endoscopy found a mucosal tear at the gastric cardia consistent with Mallory\u2013Weiss syndrome. Seven days after the first scan the abnormal right-sided position resolved on CT, but two months later the patient had another episode of haematemesis and the duodenojejunal junction and jejunum had again shifted to the right. Because the small bowel moved back and forth rather than staying in the wrong position, true intestinal malrotation was considered unlikely. The working diagnosis was dysplasia (abnormal development) of the ligament of Treitz, meaning the ligament that normally helps fix the upper small intestine was not holding the jejunum securely. At laparotomy the ligament of Treitz was present but did not fully fix the upper jejunum to the back wall of the abdomen (retroperitoneum); the pararenal area also appeared loosely fixed and mobile on CT. These factors probably allowed the jejunum to fold and deviate to the right.

Septal surfing technique (SST) was then used to identify a viable septal channel. A Sion wire, supported by a 150-cm Finecross, was advanced retrogradely through a distal septal branch into the distal RCA. A Gaia 3 traversed the RCA CTO retrogradely into the proximal RCA true lumen and was advanced into a Guidezilla guide extension catheter positioned in the antegrade guide. The Finecross was delivered to the antegrade guide and an RG3 wire was externalized. The CTO segment was predilated with a 2.0 \u00d7 15 mm balloon and stented with two overlapping DES (2.5 \u00d7 38 mm and 3.0 \u00d7 38 mm), achieving an excellent angiographic result with TIMI 3 flow in all distal branches. Dyspnea was relieved at discharge, and at 6-month follow-up there was no recurrence of dyspnea.","summary":"Patient concerns:\nThis is a 69-year-old male with prior history of coronary artery bypass grafting presented with severe dyspnea at mild exertion (NYHA III) of 2 months duration.\n\nDiagnosis:\nThe patient was diagnosed as heart failure caused by ischemia after SVG failure (SVG to right coronary artery) according to electrocardiogram, plasma N-terminal pro-B-type natriuretic peptide levels, and coronary angiogram.\n\nInterventions:\nWe recanalized native right coronary artery CTO by retrograde approach using septal collaterals by surfing technique after recanalization of totally occluded left coronary artery.\n\nOutcomes:\nDyspnea was relieved at discharge.

In August 2022, a posterior mediastinal tumour was found in the preoperative assessment for a knee surgery, which was why she was referred for evaluation and treatment. On admission, the physical examination was not relevant and the laboratory studies were within normal parameters. A chest CT scan was performed that showed a tumour located in the posterior right mediastinum measuring 6.5 \u00d7 4.2 cm, with well-defined borders, with a fat and solid density, with no evidence of bone erosion or infiltration of surrounding tissue. A biopsy of the lesion was performed using a 18G \u00d7 250 mm semiautomatic cutting needle, with image guidance, through a posterior approach. In the histopathological study, a benign neoplasm consisting of mature adipose tissue with areas of haemorrhage alternating with haematopoietic elements, predominantly precursors of the red series, was observed, as well as elements of the myeloid series in different stages of maturation and megakaryocytes, which established the diagnosis of MPM.  Finally, with the diagnosis established and the characteristics of the lesion, conservative management was decided.

Two years after diagnosis, he developed an early CNS relapse, so he was treated according to the InteReALL HR 2010 protocol with bortezomib. During induction, after being neutropenic for four weeks (20 neutrophils\/\u03bcL), he was receiving prophylaxis with cefepime, cotrimoxazole and fluconazole. In addition, he was being treated with acyclovir for a herpes simplex virus 1 skin infection. In this context, he developed a severe headache that did not respond to usual analgesia. A cranial computed tomographic scan was performed that showed a hypodens lesion in the right temporal lobe. When the possibility of an infectious origin was considered, a lumbar puncture was performed and cefepime was replaced with meropenem and vancomycin.\n\nDespite remaining afebrile, he developed signs of septic shock on the first day after admission to the clinic and was transferred to the paediatric intensive care unit for inotropic and vasoactive support. In addition, the antimicrobial spectrum was extended with gentamicin and caspofungin.\n\nThe blood analysis showed a progressive increase in C-reactive protein and procalcitonin (up to 312 mg\/L and 47.58 ng\/mL, respectively, on the third day of evolution), with no other relevant biochemical alterations. The blood count showed pancytopenia due to chemotherapy. The blood cultures ruled out bacteremia and fungemia, and herpes virus serologies were negative. The urine culture and the fecal culture were also negative. The biochemical analysis of the cerebrospinal fluid was completely normal (glucose, 63 mg\/dL; proteins, 16 mg\/dL; leukocytes 1\/\u00b5L), but the presence of B. cereus was detected in the microbiological study (sensitive to meropenem, vancomycin, linezolid and ciprofloxacin). The presence of herpes simplex 1 and 2, herpes virus 6, cytomegalovirus, varicella-zoster virus, enterovirus, parechovirus, toxoplasma, Neisseria meningitidis, Listeria monocytogenes, Streptococcus pneumoniae and Cryptococcus was ruled out in the cerebrospinal fluid.\n\nThe EEG showed diffuse slowing of brain activity with no clear epileptiform activity. On day 4, after the haemodynamic support was removed, a cranial MRI showed two hyperintense lesions in T2 and FLAIR that involved the subcortical region of the right temporal and parietal lobes. The parietal lesion had ring enhancement after administration of gadolinium and both lesions showed peripheral diffusion restriction. In addition, small haemorrhagic foci were observed scattered in the brain parenchyma. The image suggested a bacterial origin with an atypical germ, and these findings, together with those of the cerebrospinal fluid, led to the diagnosis of B. cereus abscess.\n\nAfter two weeks of treatment, the patient had a favorable outcome with resolution of the headache and no neurological findings. A follow-up MRI showed a decrease in the size of the lesions. Vancomycin and acyclovir were discontinued after three weeks and meropenem was continued for six weeks.\n","diff_label_texts":"A 10-year-old boy receiving chemotherapy for acute lymphoblastic leukemia developed a brain abscess during induction therapy.
