Anterior, lateral, and posterior cutaneous nerve entrapment syndromes have been proposed as etiologies of trunk pain. However, while these syndromes are analogous, comprehensive reports contrasting the three subtypes are lacking. We therefore reviewed the literature on anterior, lateral, and posterior cutaneous nerve entrapment syndrome. ⋯ These syndromes are usually diagnosed based solely on unique history and examination findings; however, the diagnostic process may be prolonged, and multiple re-evaluations are required. The most common first-line treatment is trigger point injection; however, the management of refractory cases remains unclear. Awareness of this disease should be expanded to medical departments other than general medicine.

An 80-year-old man presented with electrolyte abnormalities, particularly hypocalcemia (3.6 mg/dL). He was diagnosed with bone and lymph node metastases from prostate cancer seven years earlier and continuously received goserelin, bicalutamide, and zoledronate. ⋯ Given the acquired onset and clinical course, we diagnosed the patient with zoledronate-induced proximal renal tubular acidosis. In the present case, severe hypocalcemia may have been caused by malnutrition and inappropriate long-term use of zoledronate.

Citrin deficiency (CD) is a hereditary disorder caused by SLC25A13 mutations that manifests as neonatal intrahepatic cholestasis caused by CD (NICCD), failure to thrive and dyslipidemia caused by CD (FTTDCD), and adult-onset type 2 citrullinemia (CTLN2). Citrin, an aspartate-glutamate carrier primarily expressed in the liver, is a component of the malate-aspartate shuttle, which is essential for glycolysis. Citrin-deficient hepatocytes have primary defects in glycolysis and de novo lipogenesis and exhibit secondarily downregulated PPARα, leading to impaired β-oxidation. ⋯ Medium-chain triglyceride (MCT) supplements are effective for treating CD by providing energy to hepatocytes, increasing lipogenesis, and activating the malate-citrate shuttle. However, patients with CD often exhibit growth impairment and irreversible brain and/or liver damage. To improve the quality of life and prevent irreversible damage, MCT supplementation with a diet containing minimal carbohydrates is recommended promptly after the diagnosis.

Review Case Reports
Small Bowel Obstruction Caused by Migration of Fractured Metal Stent in Patients with Malignant Gastric Outlet Obstruction: A Report of Two Cases and Review of the Literature.
Gastroduodenal stenting (GDS) is a less invasive alternative to gastrojejunostomy for the management of malignant gastric outlet obstruction (mGOO). GDS is a minimally invasive treatment with good technical and clinical success, and severe complications that require surgical intervention are rare. ⋯ Adverse effects of stent fractures in patients with mGOO have rarely been reported. We herein report two surgical cases of small bowel obstruction caused by the migration of fractured metal stent in patients with mGOO.

Review Case Reports
A Significant Increase in the Serum Carbohydrate Antigen 19-9 Level Accompanied by Acute Cholecystitis and Choledocholithiasis: A Case Report and Review of the Literature.
An 80-year-old man with jaundice and fatigue was referred to our hospital. A laboratory examination revealed increased levels of hepatobiliary enzymes, and CA19-9 levels increased to 29,512 U/mL. Based on the findings of imaging examination and laboratory data, the patient was diagnosed with acute cholecystitis and choledocholithiasis. ⋯ Antibiotic administration was commenced, and the common bile duct stone was endoscopically removed. One month after treatment, the CA19-9 level decreased to within the normal range. One year after treatment, imaging examinations did not reveal any malignancy.
