Snake bite is a common and very important issue threatening health worldwide. Patients who develop hemorrhagic or non-hemorrhagic blisters following snakebite, in addition to anti-venom, need broad-spectrum antibiotics and sometimes emergency surgical procedures and hospitalization to prevent serious complications such as necrotizing fasciitis, compartment syndrome.

Hepatorenal syndrome is a rare life-threatening complication of acetaminophen toxicity. It is not responsive to fluid therapy and need performing an emergent liver transplantation. Here, we introduce a 24-year-old woman with a history of chronic high doses of acetaminophen consumption, presenting with nausea, vomiting, lethargy, oliguria, and severe metabolic acidosis.

The clinical symptoms, blood laboratory data, O2 saturation and high resolution computed tomography (HRCT) findings are critical factors in diagnosis of COVID-19 infection. In this study, 105 hospitalized patients suspected of having COVID-19 were evaluated. Finally, the data of 83 confirmed cases by HRCT and RT-PCR were analyzed. 61.40% of the patients had a comorbidity disease. 89.20% had fever, 92.00% cough, 91.40% dyspnea. Abnormal CRP seen in 77.80% of the patients following by 66.70% lymphopenia, and 60.30% neutrophilia. Also, ALP (abnormal vs. normal) and score of HRCT assessment variables had a significant effect on the positiveness of HRCT findings. 87.95% had abnormal HRCT with 41% bilateral multilobar patchy ground glass opacity (GGO). Moreover, there was a statistically significant association between level of O2 saturation and HRCT results. Our findings showed that male patients with middle age and comorbidity disease were more susceptible to the COVID-19 infection. Additionally, clinical features, blood laboratory findings, O2 saturation and HRCT findings are critical factors in prognosis of COVID-19 infection.

Human linguatulosis is a considerable medical problem in endemic regions. The infection is caused by a cosmopolitanfood-borne zoonoticparasiteLinguatula serrata (L. serrata) belonging to class pentastomida.Adult parasitesreside in upper respiratory system, nasal airways and sinuses of carnivorous animals as their final hosts.Herbivorous and other ruminants as intermediate hosts reserve immatureform of parasite in mesenteric lymph nodes, liver, lungs and spleen. Human get infection with both adult and nymph stages of parasite.Halzoun syndrome(Marrara syndrome) is the most common form of human nasopharyngeal linguatulosis which is transmitted through ingestion of L. serrata nymphs (adult stage) found in intermediate host’s organs and resulting in nasopharyngeal linguatulosis with signs of pharyngitis, salivation, dysphagia, and cough.r. This review includes previous studies on L. serrata conducted in Iran and other countries from 1940 to 2019. A systematic search is undertaken on five English and five Persian databases for English or Persian publications describing human linguatulosiscases in the world .Totally, 30 papers reporting 62human linguatulosiscases from various regions of the world are included in this review.All included papers were from the English databases. The age of patients ranged from 8 to 79 years, and the mean age was 25.8 years. Of all the patients, 41(66.1%) were female and 21(33.9%)were male. The highest number of cases (n = 25) was reported from Sudan.The nasopharynxwas the most commonly reported anatomical location of human linguatulosis cases.As a result, we think that physicians should consider L. serratainfestation in patients attending to the health foundations with complaintssuch as pharyngitis, accompanied by pharyngeal pain,coughing, sneezing and vomiting.
