Nearly every 100 years, humans collectively face a pandemic crisis. After the Spanish flu, now the world is in the grip of coronavirus disease 2019 (COVID-19). First detected in 2019 in the Chinese city of Wuhan, COVID-19 causes severe acute respiratory distress syndrome. ⋯ Several diagnostic modalities have been advocated and evaluated; however, in some cases, diagnosis is made on the clinical picture in order not to lose time. A consensus on what constitutes special treatment for COVID-19 has yet to emerge. Alongside conservative and supportive care, some potential drugs have been recommended and a considerable number of investigations are ongoing in this regard.

Case Reports
Surgical and Endoscopic Treatment of a Double Phytobezoar Causing Ileus and Jaundice: A Case Report.
Bezoars are rare conditions of mechanical intestinal occlusion. Among the various types of bezoars, phytobezoars and trichobezoars are the most common types. Symptoms are usually indistinguishable from other more common entities; therefore, it may be difficult to reach a correct diagnosis. ⋯ Three months later, the follow-up gastroduodenoscopy and CT scan revealed no signs or symptoms of any gastrointestinal mass. The present case report is the first presentation of a double gastrointestinal phytobezoar that caused ileus and temporary jaundice. Moreover, a successful single-session mechanical-electrical fragmentation of a large gastric phytobezoar is described for the first time.

The Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two ends of the spectrum of severe immunobullous state characterized by keratinocyte apoptosis. The present study aimed to draw attention to various epidemiological features of SJS and TEN diseases such as causative drugs, underlying diseases, duration of hospitalization, and types of treatment. The records of all patients with the diagnosis of SJS, TEN, and SJS/TEN overlap during 2010-2015 were retrospectively reviewed. ⋯ The most commonly consumed drug was Lamotrigine (21.6%) and the most common drug category was anticonvulsants (46.4%). In line with many studies, especially in Iran, Lamotrigine and anticonvulsant drugs were the most common causative drug and epilepsy was the most common underlying disease. Patients with SJS/TEN overlap or TEN were treated with combination therapy, whereas SJS patients received systemic corticosteroids.

Several techniques have been proposed to prevent hypotension in obstetric patients. Ephedrine and phenylephrine are individually used to prevent maternal hypotension; however, each has its own drawbacks. Some researchers have reported that the infusion of combined ephedrine and phenylephrine immediately after spinal anesthesia for cesarean delivery reduces the incidence of maternal hypotension. ⋯ The need for vasopressors and inotropes to treat hypotension, nausea, and vomiting were higher in the placebo group. First- and fifth-minute Apgar scores were higher in the study group. The prophylactic infusion of low-dose ephedrine and phenylephrine before spinal anesthesia for cesarean delivery can be used to decrease the frequency and severity of maternal hypotension and its side effects to the mother and neonate.

Single spinal anesthesia in transurethral resection of bladder tumor (TURBT) has been reported to be unable to prevent obturator nerve stimulation and adductor muscle contraction, which can cause complications like bladder perforation. The present study aimed to compare the effectiveness of the classic and inguinal approaches for obturator nerve block (ONB ). Seventy patients with cancers of the lateral wall of the bladder, scheduled to undergo TURBT at Imam Reza Hospital (Tabriz, Iran) during a 6-month period as of June 2016, were randomly allocated to groups of inguinal and classic methods (n=35). ⋯ The block onset time was shorter in the inguinal group (1.5±0.66 min vs. 2.9±1.18 min; P<0.001). Dissatisfaction of the patient (19 cases vs. 2 cases) and the surgeon (10 cases vs. no case) was higher in the classic group (P<0.001). Compared to the classic approach, the inguinal approach for ONB appeared to be an easily performable, effective block with a high success rate, rapid onset, and good patient and surgeon satisfaction.
