Hypereosinophilic syndrome (HES) is a disorder characterized by elevated levels of eosinophils, which may be associated with multi-organ involvement depending on severity. The recent diagnostic criteria for idiopathic HES require an elevated absolute eosinophil count (AEC) above 1500 cells/mcL with evidence of tissue damage. We present a case of a 37-year-old male firefighter with a purported history of eosinophilic bronchitis who was referred to the hospital with syncopal episodes and a persistent productive cough. The patient showed an AEC of 4500 cells/mcL on admission associated with high inflammatory markers. Cardiac imaging demonstrated acute myocarditis with heart failure and a reduced ejection fraction. Chest imaging was initially suggestive of community-acquired pneumonia. Workup was negative for a malignant etiology; infectious causes similarly were excluded. After a multidisciplinary evaluation, a diagnosis of idiopathic HES was made and steroids were instituted with rapid resolution of symptoms. Our case illustrates the importance of considering hypereosinophilia as a precipitating factor for acute heart failure in an otherwise healthy adult. An expeditious diagnosis can lead to early initiation of steroids to avoid progression toward multi-organ failure.

Background: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a very rare and a slowly conspicuous progressing chronic lung disease, which usually involves the upper lobes of the lung. This unusual disease, first recognized as a rare idiopathic interstitial pneumonia in 2013, is characterized by dense fibrosis of the visceral pleura and the subjacent lung parenchyma accompanied by elastosis predominating in the subpleural alveolar walls. In the interest of improving our understanding of this uncommon disease, we report a case of IPPFE established by pathology results. Case report: A 73-year-old male patient, smoker, with a medical history of chronic obstructive pulmonary disease, presented since January 2022 with a gradual worsening of dyspnea on exertion and productive cough with weight loss. The chest X-ray detected a thoracic distention. The chest high resolution computed tomography revealed biapical subpleural parenchymatous condensations with tractive bronchiectasis and pleural retraction in the right upper lobe and diffuse bilateral cento-lobular emphysema. A scan-guided trans-parietal lung biopsy showed lung parenchyma tattooed with anthracosic deposits, largely remodeled by fibrous tissue, intermingled with numerous wavy and refractive dyselastotic structures in polarized light. The orcein staining confirmed the presence of excess elastosic fibers within these lesions. All etiological investigations were negative. His lung function studies revealed a reversible obstructive ventilatory disorder. Following a multidisciplinary discussion, the diagnosis of IPPFE was confirmed on the basis of the distribution in the upper lungs on chest computed tomography combined with pathology pattern. Conclusions: This case emphasizes the atypical misleading radiological presentation of IPPFE and the key role of pathological results in establishing the diagnosis. Hence, further studies are needed to improve our understanding of this uncommon disease and to establish clear-cut guidelines for IPPFE diagnosis and management.

Macroglossia, an uncommon anatomical anomaly, can manifest as either congenital or acquired. The size of the tongue undergoes variations with age, peaking at 8 years and reaching full maturity at 18 years. Congenital macroglossia stems from diverse conditions, such as muscular hypertrophy, hemangioma, lymphangioma, Down syndrome, and others. Acquired macroglossia can result from malignancies, endocrine and metabolic disorders, chronic infectious diseases, and head and neck infections, among other factors. Additionally, extended-prone surgery can lead to its development. The incidence of macroglossia is likely underreported. This presentation is rare with only six reported cases in the literature.

Nasal septal abscess is an uncommon otolaryngologic condition with little reported in the literature. Most commonly arising secondary to hematoma, idiopathic abscess formation is rare. A previously healthy 13-year-old male with no preceding nasal hematoma or trauma presented with rhinorrhea, nasal pain, and obstruction. Initial incision and drainage were not curative; the patient returned to care with complaints of new-onset headache. Neuroimaging revealed abscess recurrence alongside pansinusitis and epidural empyema. The patient was transferred to a tertiary care center for joint otolaryngologic and neurosurgical care. The patient\'s postoperative course was uncomplicated. Nasal septal abscesses have become increasingly uncommon, but they still occur. Prompt treatment is warranted to mitigate the potential risk of further intracranial spread and facial deformity, as seen in this case.

Nasal septal abscess (NSA) is considered a rhinologic emergency. Fortunately, the incidence of NSA has markedly reduced due to the introduction of antibiotics and easy access to medical care. NSA commonly results from infection in the space between the nasal septum and the overlying mucoperichondrium and/or mucoperiosteum, typically secondary to nasal septal hematoma, but it can also be idiopathic. Prompt diagnosis and intervention are critical to avoid further complications. This paper reports the case of a 46-year-old man with no known risk factors for NSA. He was treated with broad-spectrum antibiotics, and the surgical treatment involved incision and drainage with the intraoperative placement of a Penrose drain and a silastic sheet on postoperative day five. The patient was discharged without complications such as septal perforation or saddle nose deformity.

UNASSIGNED: Acute idiopathic cervical kyphosis (AICK) represents a rare entity, and its management remains controversial. Preoperative surgical planning and individual decision-making seem necessary. To date, there is a lack of sufficient evidence and clear guidelines.
METHODS: A 21-year-old male was referred with a progressive cervical deformity detected 3 months earlier. The patient suffered from severe progressive myelopathy and represented neither neck trauma nor a familial history of similar expected conditions. His cervical imaging revealed 95 degrees of cervical kyphosis. After 3 separate surgical sessions for 360-degree fixation, the cervical kyphosis was reduced by 90 degrees. No facet dislocation was observed, and laminectomy was unnecessary. Post-operative neurological examination detected significant improvement. Six months and 2-year follow-ups were favorable. To the authors\' knowledge, the current case had the most extensive degree of cervical kyphosis reported in the literature.
UNASSIGNED: Multistage correction of AICK would result in a favorable outcome and reduce the risk of complications. Particular attention should be paid to the wide inter-spinous spaces in high grades of kyphosis during sub-periosteal dissection to prevent iatrogenic spinal cord injuries.
CONCLUSIONS: The present work may provide the first report on the role of cervical postural habits in patients with opiate substance abuse disorder, which could have triggered cervical kyphosis in this particular patient. Multistage correction of AICK would result in a favorable outcome and reduce the risk of complications.

Megaduodenum is a rare clinical syndrome characterized by significant duodenal dilation, elongation, and hypertrophy. Given its rarity and nonspecific clinical manifestations, megaduodenum may be misdiagnosed, leading to delays in surgical care and increased morbidity. We describe a case of idiopathic megaduodenum in a teenage Caucasian female, who presented with a five-year history of halitosis, recurrent belching, bloating, nausea and vomiting, and postprandial epigastric abdominal pain. She was diagnosed with megaduodenum by dramatic findings on contrast radiography. She developed a duodenal volvulus necessitating emergency exploratory laparotomy, during which a duodenal plication and a side-to-side duodenojejunostomy were performed. Exploratory laparotomy and histopathological analysis were unrevealing of any definitive abnormalities to explain her megaduodenum. Postoperatively, she developed two early small bowel obstructions, both from subsequent adhesions requiring repeat laparotomy with adhesiolysis. She has subsequently recovered without incident. Diagnosis and accurate classification of megaduodenum requires surgical exploration with a full-thickness biopsy and subsequent histopathologic analysis to rule out obstructive or functional disorders of the duodenum. Treatment of megaduodenum depends on the underlying cause and degree of duodenal distention. It is crucial that clinicians are knowledgeable of the various surgical options, their indications, and the potential postoperative complications that may arise.

UNASSIGNED: Abdominal cocoon syndrome (ACS), as a rare cause of mechanical intestinal obstruction, can be divided into primary/idiopathic vs. secondary type. The primary ACS is often asymptomatic and only diagnosed in exploratory laparotomy. The major treatment of surgery can be challenging. Since the gut wall and peritoneum are densely adhered, gut perforation might occur during adhesiolysis. Thus, it is important to have an experienced surgeon to perform the surgery.
UNASSIGNED: The authors present a primary ACS case of a 50-year-old man. The patient demonstrated an unbearable upper abdominal pain upon admission. A computed tomography (CT) scan showed a severe bowel obstruction. An exploratory laparotomy was indicated, leading to the diagnosis of ACS, which was considered idiopathic after ruling out secondary factors. An adhesiolysis was performed successfully. Note that the entire intestine measured was only 2.1 m during the surgery. There was no post-surgical complication. The patient was recovered uneventfully.
UNASSIGNED: The aetiology of primary ACS is unknown. The incidence is comparatively low and considered equal between men and women. As a rare cause of gut obstruction, the suspicion of the diagnosis should be strengthened. Surgery including adhesiolysis and bowel resection remains the major treatment. If adhesiolysis fails, bowel resection will be inevitable. The knowledge and experience of surgeon will be tested.
UNASSIGNED: The aetiology of primary ACS should be further explored. And the differential diagnosis of bowel obstruction should cover ACS in order for the surgeon to be prepared before surgery.

BACKGROUND: Pneumatosis cystoides intestinalis (PCI) is a condition characterized by the presence of gas-filled cyst-like structures in the submucosa and subserosa of the small or large intestine and in some cases accompanied by pneumoperitoneum. PCI is commonly considered a benign condition as opposed to pneumatosis intestinalis in life-threatening conditions such as mesenteric ischemia. Only a minority of cases of PCI are assumed to be primary or idiopathic with the majority being caused by a variety of underlying conditions. Symptoms of PCI are non-specific or may be absent altogether. Provided that there is no suspicion of an underlying life-threatening disease, PCI can be treated non-operatively.
METHODS: We present the case of a 71-year-old patient with pneumatosis intestinalis with free intraperitoneal gas known for three years. Due to self-limiting symptoms and lack of evidence of a life-threatening underlying disease, no specific therapy had been carried out so far. No underlying diseases could be found. Because of recurrent worsening abdominal pain and newly diagnosed partial small bowel obstruction with radiological signs of mesenteric torsion, resection of the affected small bowel was successfully performed.
CONCLUSIONS: Non-surgical management of PCI is possible provided that life-threatening causes of pneumatosis have been ruled out. Bowel obstruction is a rare complication of PCI which requires surgical treatment.
CONCLUSIONS: Our case report illustrates that symptoms of PCI may worsen over time, and that complications requiring surgical intervention may occur. We recommend regular monitoring of patients who are primarily treated non-operatively.
