RESUMEN

Nonclassic congenital adrenal hyperplasia (NCCAH) is characterized by mild cortisol deficiency, excess androgens and adrenocorticotropin (ACTH) production, and often with various features of dysmetabolic syndrome. Elective bariatric surgery is one of the most effective long-term management strategies for severe obesity. Our case presents a 34-year-old woman with symptomatic NCCAH and class III obesity who status post Roux-en-Y gastric bypass (RYGB) had significant weight loss with metabolic resolution of NCCAH, and no longer required glucocorticoid (GC) therapy. At 11 months post operation and off GC therapy, she had a weight deficit of approximately 160 pounds (72.57 kg) with continued metabolic resolution of NCCAH markers including ACTH, 17-hydroxyprogesterone, and androstenedione. Presently, GC therapy remains one of the few available treatments for symptomatic NCCAH; however, long-term GC therapy has the potential for various complications and side effects. Our case presents elective bariatric surgery as a potential and unique treatment option for patients with NCCAH with associated class III obesity. The exact pathophysiologic basis for this effect and its potential role in long-term management of appropriate NCCAH patients requires further study.

RESUMEN

Tuberculosis is a communicable disease with high morbidity and mortality rates in developing countries. The study's primary objective is to compare conventional methods such as acid-fast bacillus (AFB) culture and microscopy with rapid diagnostic methods. The secondary objective is to compare histopathological and microbiological findings in suspected patients with tubercular lymphadenitis. A total of 111 samples (August 2018 to September 2019) of lymph nodes were processed for AFB microscopy, AFB cultures, drug-susceptibility testing (DST), histopathology, and Xpert Mycobacterium Tuberculosis (MTB)/resistance to Rifampin (RIF) assays. Out of 111 lymph node samples, 6 (5.4%) were positive for AFB smear microscopy, 84 (75.6%) were positive for AFB culture, 80 (70.7%) were positive on Gene Xpert, and 102 (91.8%) were indicative of tuberculosis for histopathology studies. Mycobacteria growth indicator tube (MGIT) culture positivity was 84 (75.6%) higher than solid Lowenstein-Jensen (LJ) culture 74 (66.6%). Positive cultures underwent phenotypic DST. Two cases were Multidrug-resistant (MDR) on DST, while three cases were Rifampicin resistant on Gene Xpert. The sensitivity of Genexpert was (62%) against the conventional AFB culture method. The poor performance of conventional lymphadenitis diagnostic methods requires early and accurate diagnostic methodology. Xpert MTB/RIF test can help in the treatment of multidrug-resistant TB cases. Nonetheless, rapid and conventional methods should be used for complete isolation of Mycobacterium tuberculosis.


A tuberculose é uma doença transmissível com altas taxas de morbimortalidade nos países em desenvolvimento. O objetivo principal do estudo é comparar métodos convencionais, como cultura de bacilo álcool-ácido resistente (BAAR) e microscopia, com métodos de diagnóstico rápido. O objetivo secundário é comparar os achados histopatológicos e microbiológicos em pacientes com suspeita de linfadenite tubercular. Um total de 111 amostras (agosto de 2018 a setembro de 2019) de gânglios linfáticos foi processado para microscopia de AFB, culturas de AFB, teste de susceptibilidade a drogas (DST), histopatologia e Xpert Mycobacterium tuberculosis (MTB)/ensaios de resistência à rifampicina (RIF). Das 111 amostras de linfonodos, 6 (5,4%) foram positivas para baciloscopia de AFB, 84 (75,6%) foram positivas para cultura de AFB, 80 (70,7%) foram positivas para o GeneXpert e 102 (91,8%) foram indicativas de tuberculose para estudos histopatológicos. A positividade da cultura do tubo indicador de crescimento de micobactérias (MGIT) foi 84 (75,6%), maior que a cultura sólida de Lowenstein-Jensen (LJ), 74 (66,6%). As culturas positivas foram submetidas a DST fenotípico. Dois casos eram multirresistentes (MDR) ao DST, enquanto três casos eram resistentes à rifampicina no GeneXpert. A sensibilidade do GeneXpert foi 62% contra o método convencional de cultura AFB. O fraco desempenho dos métodos convencionais de diagnóstico de linfadenite requer metodologia de diagnóstico precoce e precisa. O teste Xpert MTB/RIF pode ajudar no tratamento de casos de tuberculose multirresistente.

RESUMEN

Sarcoidosis is a multisystem granulomatous disorder characterized by non-caseating granulomas in multiple organs. It most commonly involves lungs and it is very rare to find isolated cases affecting other organ systems with no associated pulmonary findings. We hereby present a case of a young 30-year-old male who was referred to the hospital by his primary medical doctor due to right eye pain secondary to iritis and acute kidney injury (AKI). His initial laboratory studies revealed anemia, AKI, mild hypercalcemia, and the urinary analysis revealed proteinuria. Imaging studies were negative and a kidney biopsy was performed and showed results from the biopsy that revealed diffuse tubulointerstitial disease with early fibrosis, widespread moderate inflammation, multifocal tubulitis, and focal aggregate of epithelioid cells suggestive of granuloma consistent with sarcoidosis. The patient was treated with prednisone. Renal involvement of sarcoidosis is extremely rare (around 0.7%). It has a wide spectrum of presentation including abnormal calcium metabolism, nephrolithiasis, nephrocalcinosis, and acute tubulointerstitial nephritis with or without granulomas. This is a unique case as it shows renal sarcoidosis without coexisting pulmonary finding of hilar lymphadenopathy on chest X-ray. There are very few reported cases of renal sarcoidosis in the literature and this case can add to the pool of those cases. It also emphasizes the need for urgent renal biopsy in the settings of AKI associated with mild to moderate proteinuria. Lack of availability of comprehensive research on the disease may lead to misdiagnosis and delay in treatment.

RESUMEN

Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a rare extraarticular manifestation of the systemic autoimmune disease rheumatoid arthritis. RA-ILD is one of the leading causes of morbidity and mortality in patients with rheumatoid arthritis. It is more commonly seen in patients with risk factors, which include male sex, severe rheumatoid arthritis, and smoking. The presentation depends on the extent of the underlying pathology. Patients can remain asymptomatic for extended periods of time and progressively develop symptoms such as shortness of breath on exertion and a nonproductive cough. The diagnosis is made using a combination of clinical presentation, pulmonary function testing, and imaging. It is difficult for a practitioner to distinguish the presentation of interstitial lung disease from other causes and RA-ILD. However, it is extremely important to differentiate them due to the differences in management. The treatment usually involves a multidisciplinary team guided approach towards treating the underlying rheumatoid arthritis. Asymptomatic patients are managed by observation, while symptomatic patients are managed with glucocorticoids and immunosuppressants. Accurate and early treatment can lead to an improvement in a patient's symptoms and significantly improve their quality of life. We present an interesting case of a female with a long-standing history of rheumatoid arthritis not on any treatment presenting to the ED with exertional shortness of breath, dry cough, and abdominal distension.

RESUMEN

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are antihyperglycemic drugs that are currently being recommended as second-line therapy for patients with diabetes mellitus. SGLT-2 Inhibitors function by inhibiting renal cotransporters, which reduces the reabsorption of glucose in the kidney, ultimately decreasing the concentration of glucose in the body. They have gained popularity in recent years due to their protective effects on the heart and kidneys - both organ systems that diabetes mellitus has shown to have a deleterious effect on. However, despite their growing fame, they have been found to increase the risk of euglycemic diabetic ketoacidosis (DKA). Euglycemic DKA is particularly dangerous as there is a chance that it can be missed by clinicians due to glucose levels generally being less than 200 mg/dL. There is an increasing body of literature detailing cases of euglycemic DKA after bariatric surgery. We present a brief review of the literature regarding this important side effect of SGLT-2 inhibitors seen in patients after bariatric surgery.

RESUMEN

Lung cancer is one of the most common cancers diagnosed every year and accounts for a major percentage of cancer incidence and mortality annually, especially in men. Lung adenocarcinoma is a subtype of non-small cell lung cancer (NSCLC), which is the most common type of lung cancer found in smokers and nonsmokers alike. It is known to have diverse CT chest findings ranging from: ground-glass opacities (GGOs) with partially solid nodules, to single or multiple solid nodules that can be either central or peripheral, to thin-walled cystic lesions. Lesions are usually solitary but may be multifocal. Rarely, these lesions can be calcified or demonstrate cavitation, which can make it difficult to distinguish from an infectious disease like tuberculosis, pneumonia, or even fungal infections. Here, we present a case of a 36-year-old Asian male with no significant past medical history, except a 16-pack-year smoking history and recent deployment to Afghanistan, that initially presented with a chief complaint of cough of three-week duration. His CT scan showed innumerable bilateral pulmonary nodules within both lung fields with a miliary type appearance that ultimately turned out to be adenocarcinoma.

RESUMEN

Myasthenia gravis is an auto-immune disease that results in muscle weakness caused by antibodies released against acetylcholine receptors at the presynaptic membrane. Treatment options include acetylcholinesterase medications that cause a wide range of side-effects by increasing the concentration of acetylcholine at the synaptic cleft. One peculiar side effect seen is the precipitation of myocardial infarction caused by an excess of acetylcholine especially among elderly females. We present an interesting case of an 88-year-old female with a history of lung cancer newly diagnosed with paraneoplastic myasthenia gravis, started on treatment with prednisone 40 mg daily, and pyridostigmine 60 mg every six hours. She initially showed remarkable improvement in symptoms within a few hours, however, one day later, the patient developed sudden onset of chest pain radiating towards her left arm. A 12-lead electrocardiogram (EKG) showed diffuse ST-elevation in anterior leads and cardiac enzymes were found to be elevated. Pyridostigmine was stopped and the patient was started on heparin. The patient underwent cardiac catheterization which showed 50% stenosis in the right coronary artery (RCA) and 70% in the left anterior descending artery (LAD). The patient was monitored in the cardiac care unit (CCU) for 24 hours and later on discharged home on oral prednisone. It is a common practice to start treatment with anti-cholinesterase medications in newly diagnosed patients of myasthenia gravis, however, these medications can precipitate myocardial ischemia by coronary vasogenic spasm or by their arrhythmogenic effect. It is important to be aware of these outcomes while starting patients on these medications.
