Novel Coronavirus disease (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV 2) presenting mainly as an acute respiratory illness with interstitial and alveolar pneumonia. It can also affect multiple organs such as the kidney, heart, intestinal tract, blood, and nervous system. We report a 10-year-old boy presenting with severe cough, tachypnea, retraction and respiratory distress, fever, myalgia, oliguria, and anuria thereafter. He had no history of diarrhea, vomiting, or a runny nose. Laboratory findings include leukopenia and lymphopenia. CRP, ESR, and procalcitonin levels were high, but serum LDH was normal. RT-PCR test was positive. In the initial days of admission, he needed mechanical ventilation support due to ARDS and received antiviral drugs, renal replacement therapy, hemoperfusion, and other necessary supportive cares. Thirty-five days later, he weaned from the ventilator and discharged from hospital. Two weeks later, COVID-19 specific IgG was found in serologic test.

Kefir (a traditional collection of beneficial microbes) is a popular accepted beverage that usually consumed for its health-promoting effects in Iran and Caucasian regions. In this case, the beneficial effects of a kind of kefir were reported on glycated hemoglobin A (HbA1c) level, and weight loss of an indexed diabetic mellitus patient. The patient as a supplement of her routine anti-diabetic drugs consumed Probiotic kefir. After 90 days of consumption the patient, have about 4 kg weight loss, and her HbA1c decreased from 7.9 to 7.1. Depth of sleep and energizing effects of kefir was also from very remarkable findings of this case, as reported by the patient.

Brucellosis is a common zoonotic infection caused by bacterial genus Brucella, a Gram-negative bacterium, and continued to be a health problem in endemic areas. Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is an autoimmune disease which can lead to status epilepticus. A 19-year-old male patient was referred to our hospital with status epilepticus. The diagnosis of brucellosis was confirmed about 2 weeks before. The brain magnetic resonance imaging was normal. Lumbar puncture was performed, and cerebral spinal fluid (CSF) was in normal limits. The patient was treated with antiepileptic, anti-brucellosis agents. Two weeks after discharge, the patient readmitted to hospital with status epilepticus again. Extensive workup was negative except that NMDAR antibodies were detected in serum and CSF. The diagnosis of anti-NMDAR encephalitis was established. Brucellosis as a triggering factor for NMDAR encephalitis should be considered.

In recent decade the prevalence of antibiotic associated diarrhea was increased because of more antibiotic usage. Colstridum difficile is a microorganism which can cause mild to severe colitis. But the only cause of colitis related to Antibiotics is not colstridum difficle. In this case report we explain a child whit antibiotic associated colitis due to klebsiella oxtyoca.

Celery (Apium graveolens) is a popular medicinal herb that used conventionally for the treatment of different diseases. This report aimed to demonstrate celery would induce hyperthyroidism after oral celery extract consumption for weight loss. A 36-year-old female patient came to our clinic with blurred vision, palpitation, and nausea. Dietary history showed that she used 8 g/day of celery extract in powder form for weight reduction. Weight loss during 78 days of celery extract consumption was 26 kg. Thyroid function test showed that serum level of thyroid-stimulating hormone (TSH) and T4 were 0.001 mIU/L and 23 ng/dl, respectively). Grave's and thyrotoxicosis ruled out by other laboratory evaluations. Methimazole 10 mg/day was prescribed. Serum level of TSH was evaluated. The celery extraction intake was discontinued when started treatment with methimazole. Not found any thyroid stimulator (thyroxin and other) in celery extraction. We concluded that observed hyperthyroidism and allergic reaction may be induced by celery extract consumption. Therefore, it is possible that hyperthyroidism may be a side effect of frequent celery extract consumption.
