RESUMEN
Fanconi syndrome is described as a defect in the proximal tubular reabsorption of glucose, amino acids, uric acid, phosphate, and bicarbonate, falling under type 2 renal tubular acidosis (RTA). Some common causes include drugs, heavy metals, infections, and genetics (particularly mitochondrial disorders). We present a case of a 33-year-old Caucasian female with chronic alcohol use disorder. She was treated for acute kidney injury (AKI) but had persistent hypophosphatemia, hypokalemia, hypouricemia, low bicarbonate, along with glycosuria consistent with Fanconi syndrome. An exhaustive workup ruled out the most common causes. Alcohol abstinence proved to correct the underlying abnormality. Alcohol is a mitochondrial toxin, and its role in the pathophysiology of Fanconi syndrome is under investigation. Early diagnosis of Fanconi is imperative to avoid complications such as rickets and osteomalacia. Therefore, testing for markers of alcohol abuse should be considered when determining the etiology of Fanconi syndrome. Alcohol use disorder is a common disorder, with more than 3 million cases annually in the US alone. Clinicians should have a high index of suspicion for Fanconi syndrome in a patient with similar anomalous labs considering the high prevalence of alcohol use disorder. More research regarding this topic is warranted.
RESUMEN
Bevacizumab is a monoclonal anti-vascular endothelial growth factor (VEGF) antibody that binds to and makes all of the VEGF isoforms inactive, and thus prevents angiogenesis, development, and the spread of the tumor. The most reported side effects after administering bevacizumab include bleeding, high blood pressure, heart failure, proteinuria, thrombosis, and gastrointestinal perforation. Pneumothorax has rarely been reported as a complication of bevacizumab, but with an unclear mechanism. This article aims to explore the occurrence of pneumothorax as a side effect after using bevacizumab through a systematic review of current case reports published on the topic. A literature search was conducted using PubMed, Google Scholar, ScienceDirect, and Directory of Open Access through the utilization of appropriate keywords, and case reports were selected based on predefined inclusion and exclusion criteria. Our results encompass five case reports that were further evaluated for demographic, clinical, and treatment parameters. This systematic review concludes that pneumothorax can occur after bevacizumab-containing chemotherapy although this side effect is relatively rare. Awareness regarding this possible side effect can assist clinicians during their practice in considering pneumothorax as a possible differential diagnosis when encountering patients presenting with pulmonary symptoms after starting bevacizumab-containing chemotherapy; hence, timely diagnosis and treatment can save a life.
RESUMEN
A 41-year-old premenopausal woman presented to the outpatient department with a diagnosis of invasive lobular carcinoma. She noticed a lump a year back but did not seek medical attention due to many socio-cultural factors prevalent in Pakistan that prevent her from seeking medical attention earlier. She came in for a check-up after increasing in size of the lump. The bilateral mammogram showed large areas of asymmetrical density in the left upper quadrant. It was followed by an ultrasound-guided biopsy which confirmed the diagnosis of invasive lobular carcinoma. Due to stage 3, it was recommended to have CT and an MRI of the breast to assess the extent of the disease. Tissue immunohistochemistry was also requested, which came back as ER-positive, PR-positive, and HER2/neu negative. MRI of the breast revealed a 4.2 x 3.3cm heterogeneously enhancing asymmetric mass-like enhancement area within the left breast outer quadrant with an adjacent spiculated nodular lesion measuring 2.2 cm. CT chest/abdomen/pelvis with contrast showed left breast with minimal parenchymal asymmetry and a small 9 mm node seen in the left axilla. There was no evidence of metastasis. The patient was started on neoadjuvant therapy to minimize systemic disease, followed by mastectomy. This case highlights socio-cultural factors prevalent in Pakistan that lead to delays in the diagnosis and treatment of invasive lobular carcinoma. The outcome had been better if the patient sought medical attention sooner at an earlier stage. We also propose strategies to raise awareness in Pakistan for the timely diagnosis and treatment of breast cancer.
RESUMEN
Foreign body (FB) ingestion is one of the most common complaint in the emergency room and, extra-intestinal migration of penetrating sharp FBs is one of the most overlooked aspect of medical research. We report a case of accidental ingestion of a sewing needle which was recovered from the mesentery. The 28-year-old female presented to our hospital with abdominal pain and one-month's history of needle ingestion. Initially laparoscopy was performed, which was inconclusive. Afterward, through laparotomy, the needle was successfully removed from the mesentery of small bowel.
