RESUMO
Background/Aims: Noncardiac chest pain (NCCP) of esophageal origin is a challenging clinical problem of diverse etiology that affects more than 80 million Americans yearly. We assess the prevalence and impact of psychological disorders on NCCP of esophageal origin, describe possible mechanisms associated with this condition, and review psychological therapy options. Methods: Online search using PubMed and Medline from January 1, 1966, to April 30, 2023. Results: Psychological disorders have been reported in up to 79% of patients with NCCP of esophageal origin. Several psychological disturbances have been identified with this condition, including depression, anxiety, panic disorder, phobias, and obsessive-compulsive and somatoform disorders. It is unclear whether the psychological disorders trigger the chest pain or vice versa. Multiple psychological mechanisms have been linked to chest pain and may contribute to its pathogenesis and severity. These mechanisms include cardiophobia, poor coping strategies, negative social problem solving, stress and perceived control, hypervigilance to cardiopulmonary sensations, altered pain perception, and alexithymia. Psychological therapies for NCCP of esophageal origin include cognitive behavioral therapy, hypnotherapy, physical and relaxation training, breathing retraining, and alternative medicine. Among the therapeutic options, cognitive behavioral therapy has been shown to be an effective treatment for NCCP of esophageal origin. Conclusion: This review raises awareness about the high prevalence of psychological disorders in NCCP of esophageal origin and highlights the need for clinical trials and trained therapists to address the management of this taxing clinical problem.
RESUMO
AIM: The incidence of urinary tract infection (UTI) in pregnant women may vary from 5-10% and depends on parity, race, socioeconomic status and anatomical and functional changes in pregnancy. In Mexico, preterm birth accounts for 75% of perinatal deaths and 50% of the neurological sequelae attributable directly to prematurity. The objective of the present study is to describe maternal and perinatal complications in pregnant women with UTI caused by Escherichia coli and to find out the antimicrobial susceptibility pattern. METHODS: A descriptive and longitudinal study of pregnant women admitted to the Women's Hospital in Culiacan, Sinaloa, Mexico, was carried out from January 2013 to December 2014. Patients with E. coli infection were included, and infections caused by other microorganisms were excluded. The sociodemographic variables, causes of hospitalization and the type of maternal and perinatal complications were determined. RESULTS: The causes of admission to the hospital were threatened preterm labor, and fever and threatened abortion. Of 38 patients with threatened preterm labor, 33 went on to delivery, four were preterm births and two were neonatal deaths. E. coli was sensitive to over 90% of piperacillin-tazobactam, amikacin, nitrofurantoin and carbapenems. CONCLUSION: According to this study in a Mexican population, the number one admission diagnosis in women with UTI due to E. coli was threatened preterm labor, and fever and threatened abortion. E. coli was sensitive to more than 90% of piperacillin-tazobactam, amikacin, nitrofurantoin and carbapenems.

INTRODUCTION: Cleft lip and palate, the most common developmental deformity, is seen worldwide and the etiology involves a combination of genetic and environmental factors. The purpose of this study was to determine the maternal risk factors associated with the development of cleft lip and cleft palate. MATERIALS AND METHODS: We conducted a case control study at the Women's Hospital in Culiacan, Mexico. Medical records were analyzed, including patients who delivered babies with and without cleft lip and cleft palate from January 2010 to December 2015. Multiple variables were analyzed, including gestational age, weight at birth, the use of folic acid and multivitamins during pregnancy, smoking, alcohol abuse, the use of recreational drugs, history of sexually transmitted infections, marital status, socioeconomic status, education, and nutritional status. RESULTS: We found that the maternal risk factors with the strongest association for the development of cleft lip and cleft palate were the following: patients who were not taking folic acid during pregnancy [OR 3.27, 95% CI 1.32-8.09], P=0.00; patients who were not taking vitamin supplementation during pregnancy [OR 2.6, 95% CI 1.19-7.27], P=0.02; smoking during pregnancy [OR 2.05, 95% CI 1.23-3.41], P=0.01; and alcohol abuse during pregnancy [OR 1.90, 95% CI 1.17-3.08], P=0.03. CONCLUSIONS: The main risk factors associated with the development of cleft lip and cleft palate in a Mexican population at the Women's hospital in Culiacan, Sinaloa, Mexico were smoking, alcohol abuse, and patients not taking folic acid and multivitamins during pregnancy.
RESUMO
Pleural effusions are one of the rarest complications reported in patients with silicone gel filled breast implants. The silicone implants have potential to provoke chronic inflammation of pleura and subsequent pulmonary complications such as pleural effusion. Herein, we report a 44-year-old female who presented with left sided pleural effusion, six weeks after a silicone breast implantation surgery. The most common infectious, inflammatory, and malignant causes of pleural effusion were excluded with pleural fluid cytology and cultures. With recurrent effusion in the setting of recent surgery, the chemical reaction to silicone breast implants was sought and exploration was performed which revealed foreign body reaction (FBR) to silicone material. The symptoms dramatically improved after the explantation.
RESUMO
Neuroarthropathy (neuropathic osteoarthropathy), also known as Charcot joint, is a condition characterized by a progressive articular surface destruction in the setting of impaired nociceptive and proprioceptive innervation of the involved joint. It is seen most commonly in the foot and ankle secondary to peripheral neuropathy associated with diabetes mellitus. Cases of hip (Charcot) neuroarthropathy are rare and almost exclusively reported in patients with neurosyphilis (tabes dorsalis). We report a case of a 36-year-old man who presented to the emergency department complaining of right hip pain. On physical examination, pain and thermal sensory deficits were noted in the upper torso with a cape-like distribution, as well as signs of an upper motor neuron lesion in the left upper and lower extremities. A magnetic resonance imaging study (MRI) of the right hip showed evidence of early articular surface destruction and periarticular edema consistent with hip Charcot arthropathy. An MRI of the spine revealed an Arnold-Chiari type I malformation with extensive syringohydromyelia of the cervical and thoracic spine.
RESUMO
Chylous ascites is very rare in HIV/AIDS and its association with Mycobacterium avium complex-immune reconstitution inflammatory syndrome (MAC-IRIS) has been rarely reported. Here, we report a case of a young African-American male who developed chylous ascites as a late sequela to immune reconstitution inflammatory syndrome while on treatment for MAC. Antiretroviral drug-naive patients who start HAART in close proximity to the diagnosis of an opportunistic infection and have a rapid decline in HIV RNA level should be monitored for development of IRIS. Although the long term prognosis is poor, early diagnosis and treatment help to improve quality of life.
RESUMO
A 46-year-old African-American male with past medical history significant for Kartagener's syndrome, essential hypertension, and HIV presented with acute chest pain. ECG and troponins indicated an acute myocardial infarction. Ventriculography confirmed dyskinesia of the left ventricle, with an EF of 25%. However the coronary catheterization showed nonobstructed coronaries. Ventricular contraction and EF were restored in 4 weeks. To our knowledge, this is the first incidence of Takotsubo's reported in a young patient with Kartagener's syndrome. Chronic lung disease may contribute to the development of Takotsubo's cardiomyopathy, which is a documented yet not fully understood phenomenon.
RESUMO
A 25-year-old Hispanic female with a history of anemia, schizoaffective disorder, and psychosis was admitted for anemia associated with fatigue, weakness, shortness of breath, night sweats, weight loss, and abdominal and lower back pain for the past two months. On routine management, she was found to have a positive serum b-HCG of 80.4 (0-5 mIU/mL) but the patient denied any sexual activity in her life. During her admission, U/S of the pelvis was noncontributory. CT angiogram of the chest was significant for prominent mediastinal and hilar lymph nodes, diffusely thickened stomach suggesting gastric malignancy with multiple hypoenhancing lesions in the liver and diffuse lytic lesions in the spine and sacrum suspicious for metastatic disease. The MRI of the abdomen confirmed the CT angiogram findings. After these findings, EGD was performed which showed lesions in the antrum, body of the stomach, fundus, and cardia on the lesser curvature of the stomach body correlating with carcinoma. The biopsy was positive for Her2, b-HCG producing poorly differentiated gastric adenocarcinoma. Patient underwent one successful round of chemotherapy with Taxotene, Cisplatin, and 5-FU for Stage IV gastric adenocarcinoma.
RESUMO
A 50-year-old AIDS patient with a CD4 T-cell count of 114/mm(3) was admitted with cerebellar symptoms of left CN XI weakness, wide-based gait with left-sided dysmetria, abnormal heel-knee-shin test, and dysdiadochokinesia. MRI showed region of hyperintensity in the left inferior cerebellar hemisphere involving the cortex and underlying white matter. Serological tests for HSV1, HSV2, and syphilis were negative. Her CSF contained high protein content and a WBC of 71/mm(3), predominantly lymphocytes. The CSF was also negative for cryptococcal antigen and VDRL. CSF culture did not grow microbes. CSF PCR assay was negative for HSV1 and HSV2 but was positive for JC virus (1,276 copies). The most likely diagnosis is granule cell neuronopathy (GCN), which can only be definitively confirmed with biopsy and immunohistochemistry.
RESUMO
Adenocarcinoma of the lung is the most common form of lung cancer in nonsmokers. It is commonly seen in the periphery of the lungs. Myasthenia gravis is generally associated with mediastinal malignancies and rarely associated with adenocarcinoma of the lung. We present a case of a 38-year-old male nonsmoker with rapidly progressive adenocarcinoma of the lung associated with myasthenia gravis, a patient whom expired within 27 days of hospital admission and diagnosis.
RESUMO
The presence of Strongyloides stercoralis infection in patients with systemic lupus erythematosus (SLE) has been described previously. Strongyloides stercoralis hyperinfection syndrome (SHS) that usually develops in patients under immunosuppressive therapy may affect a variety of organs, but the presentation with diffuse alveolar hemorrhage (DAH) is rare with only a few cases described in the literature. We present the case of a 36-year-old Hispanic female with a past medical history relevant for SLE and a recent diagnosis of lupus nephritis and hypertension. The patient who developed sudden and progressive abdominal pain and respiratory distress, with the presence of bilateral crackles and severe hypoxemia, is currently under treatment with steroids and cyclophosphamide for worsening of lupus nephritis. The patient underwent endotracheal intubation and mechanical ventilation, and computed tomography showed the presence of bilateral pulmonary infiltrates suggestive of DAH. Bronchoalveolar lavage was done and showed the presence of filariform larvae, morphologically consistent with Strongyloides stercoralis. Treatment with ivermectin was started and patient responded to treatment with improvement of clinical status. In conclusion, the development of SHS in patients with lupus, especially when receiving immunosuppressive therapy, is a severe and potentially fatal complication. Early detection and treatment may decrease mortality.
RESUMO
The well-reported methotrexate (MTX) toxicities are based on the duration and cumulative dosing of drug. The typical toxicities can be predicted by the timing of drug administration, where mucositis occurs as an earlier effect, while myelosuppression and the sequelae of pancytopenia occur later after MTX administration. Despite these well-known toxicities, low dose MTX therapy can become problematic, in particular with the elderly, who are at a greater risk for significant myelosuppression. We present a case of a 73-year-old female with pancytopenia causing severe neutropenia, mucocutaneous bleeding, and bruising and requiring intravenous antibiotic therapy and limited transfusion dependence as a result of low dose daily MTX for rheumatoid arthritis.
RESUMO
Vanishing lung syndrome (VLS) is a rare and distinct clinical syndrome that usually affects young men. VLS leads to severe progressive dyspnea and is characterized by extensive, asymmetric, peripheral, and predominantly upper lobe giant lung bullae. Case reports have suggested an additive role of marijuana use in the development of this disease in young male tobacco smokers. We herein report a case of a 65-year-old Hispanic male previously diagnosed with severe emphysema and acquired immune deficiency syndrome (AIDS), with a history of intravenous heroin use and active marijuana smoking who presents to the emergency department with severe progressive shortness of breath he was found to have multiple large subpleural bullae occupying more than one-third of the hemithorax on chest computerized tomography (CT), characteristic of vanishing lung syndrome. The patient was mechanically ventilated and later developed a pneumothorax requiring chest tube placement and referral for surgical bullectomy. Surgical bullectomy has shown high success rates in alleviating the debilitating symptoms and preventing the life threatening complications of this rare syndrome. This case further emphasizes the importance of recognizing VLS in patients with severe emphysema and heavy marijuana smoking.
RESUMO
BACKGROUND AND AIMS: Infection with the hepatitis C virus (HVC) is one of the most common viral infections worldwide. Approximately 170 million individuals are infected worldwide. HCV is an important cause of morbidity and mortality. In Mexico, according to the National Health Survey 2000, it is estimated that 70,000 cases exist. We undertook this study to estimate the prevalence of anti-HCV antibodies in patients with association to the risk factors for HCV infection in the lowland (bajio) region. METHODS: There were 2803 individuals 15 years of age or older who were treated at the General Hospital Zone #4 who were included in this study. Following informed consent, the participants were given a questionnaire listing the major risk factors for hepatitis C. If they answered positive to any of these identified factors, a blood sample was taken to determine anti-HCV antibodies via ELISA analysis. RESULTS: Average age in this study was 38.4 ± 13.5 years, and 75.5% were female (n = 2116). Anti-HCV antibodies were isolated in 1.3% of the patients (n = 36). The most commonly identified risk factor among all the participants was a history of previous transfusions (28.8 % of all patients, n = 813 and 41.7%, n = 15 of those with positive HCV antibodies). This was the only statistically significant risk factor identified in this study (p = 0.066). CONCLUSIONS: Mexico is currently considered to have a lower prevalence for HCV in relation to developed countries and other endemic areas. The figures reported are lower than those observed in this study, suggesting that the strategies for detecting HCV in Mexico may be inadequate.

Mycotic aneurysms of the common femoral artery are rare and usually occur in intravenous drug abusers who use the femoral vessels for injection. We herein describe a case of mycotic aneurysm of the common femoral artery caused by methicillin-sensitive Staphylococcus aureus seeding of an atherosclerotic plaque in which the bacteria possibly originated from psoriatic skin lesions. A 67-year-old Caucasian man was admitted to the hospital after experiencing chest pain for two days. He was known to have psoriasis and coronary artery disease with a history of coronary artery bypass grafting surgery three years earlier. He was found to have methicillin-sensitive Staphylococcus aureus bacteremia and later developed a mycotic aneurysm of the femoral artery opposite to the site of catheterization access. Mycotic aneurysms are rare clinical conditions associated with significant morbidity and mortality. In patients with psoriasis, a high prevalence of Staphylococcus aureus colonization of the skin makes possible bacterial seeding of existing atherosclerotic plaques. Therefore, the risk of mycotic pseudoaneurysm formation in these patients should be considered.

INTRODUCTION: This study aimed to determine the resistance patterns of Escherichia coli (E. coli) in Mexico to several antibiotics and research some therapeutic options. METHODOLOGY: Positive cultures for E. coli isolated from bronchial secretions, urine, central catheter, blood, and infected wounds in the Culiacan General Hospital, Sinaloa, Mexico from 30 June 2004 to 1 July 2007 were studied. Resistance against multiple antibiotics was measured and compared by gender and the hospital unit where the bacteria were isolated. RESULTS: In total, 1511 specimens were analyzed from men (45.4%) and women (54.5%), of which 251 were positive for E. coli. Antimicrobial resistance was highest in the neurosurgery service (58.4%). Samples included sputum (14.7%), bronchial secretions (17.9%), wounds (35.4%), urine/Foley catheter tip (35.5%), central catheter tips (5.6%), and blood cultures (7.2%). Resistance to ampicillin was highest at 91% followed by ciprofloxacin at 80.6%, trimethoprim-sulfamethoxazole at 70.2%, piperacillin/tazobactam at 14.4%, and imipenem at 6.8%. CONCLUSIONS: Trimethoprim should not be recommended as an empiric option for E. coli infections and the benefit of quinolones is low. It is important to understand the resistance of the bacteria in each medical center, consider its frequency in each service within the same hospital, and take all necessary measures to ensure and create a clinical attitude of prevention.

Los abscesos hipofisarios se diagnostican en la mayoría de los casos solo después del drenaje transesfenoidal, el abordaje terapéutico de elección; son subdiagnosticados y representan una enfermedad con alta mortalidad sin el tratamiento correcto y oportuno. Este es el caso clínico de una paciente de 38 años de edad con amenorrea de un año de evolución, galactorrea, cefalea y déficit campimétrico manifestado por hemianopsia bitemporal. La resonancia magnética nuclear mostró una imagen compatible con adenoma hipofisario, por lo que se realizó abordaje transesfenoidal confirmándose por reporte histopatológico un absceso cerebral. Se llevó terapia antibiótica empírica con vancomicina, metronidazol y ceftriaxona a dosis meníngeas, sin obtener el agente causal en los cultivos. Se concluyó que los abscesos hipofisiarios son una patología potencialmente curable que al manifestarse como una masa selar la gran mayoría recibe un abordaje terapéutico adecuado por vía transesfenoidal, y en la mayoría de los casos dicho procedimiento arroja el diagnóstico y el tratamiento definitivo al mismo tiempo.
Pituitary abscesses are defined as the affection of the pituitary gland by an intrasellar suppurative process caused by an infectious agent. Pituitary abscesses represent less than 1% of the pathologies of the sellar region, the clinical manifestations are due to pituitary dysfunction or mass effect. The diagnosis in most of the cases is only after transsphenoidal drainage which is the therapeutic approach of choice, being underdiagnosed and becoming a disease with high mortality if the right and appropriate treatment is not instituted. Case report. A case of a 38-year-old-female patient with amenorrhea of one year of evolution, galactorrhea, headache and visual field deficits manifested by bitemporal hemianopsia is reported. Magnetic resonance imaging showed an image compatible with pituitary adenoma, a transsphenoidal approach was performed and histopathologic report confirmed a brain abscess. Antibiotic therapy was empirically started with vancomycin, metronidazole and ceftriaxone at meningeal doses, failed to get the agent in cultures. Conclusions. Pituitary abscesses are a potentially curable disease that present as a sellar mass, most receive the appropriate therapy by transsphenoidal approach and in most of the cases this procedure gives the definitive diagnosis and treatment simultaneously.
RESUMO
Therapeutic hypothermia (TH) is nowadays one of the most important methods of neuroprotection. The events that occur after an episode of ischemia are multiple and hypothermia can affect the various steps of this cascade. The mechanisms of action of TH are varied and the possible explanation for the benefits of this therapy is probably the multiple mechanisms of action blocking the cascade of ischemia on many levels. TH can affect many metabolic pathways, reactions of inflammation, apoptosis processes, and promote neuronal integrity. To know the mechanisms of action of TH will allow a better understanding about the indications for this therapy and the possibility of searching for other therapies when used in conjunction with hypothermia will provide a therapeutic synergistic effect.
