Low Thyroid - Could It Be A T3 Problem?
Low Thyroid - Could It Be A T3 Problem? samer kareem 5,778 Views • 2 years ago

NTIS refers to a syndrome found in seriously ill or starving patients with low fT3, usually elevated RT3, normal or low TSH, and if prolonged, low fT4. It is found in a high proportion of patients in the ICU setting, and correlates with a poor prognosis if TT4 is <4ug/dl. The patho-physiology includes suppression of TRH release, reducedT3 and T4 turnover, reduction in liver generation of T3, increased formation of RT3, and tissue specific down-regulation of deiodinases, transporters, and TH receptors. Although long debated, tissue TH levels are definitely reduced, and tissue hypothyroidism is presumably present. This is often not clinically evident because of the brief duration, and reduced but not absent tissue levels of TH. Although recognized for nearly 4 decades, interpretation of the syndrome is contested, because of lack of data. Some observes, totally without data, argue that it is a protective response and should not be treated. Other observers (as in this review) present available data suggesting, but not proving, that thyroid hormone replacement is appropriate, not harmful, and may be beneficial. The best form of treatment (TRH,TSH,or T3+T4) and possible accompanying treatments (GHRH, Cortisol, nutrition, insulin) lack consensus. In this review current data are laid out for reader’s review and judgment.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,330 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

Direct Laryngoscopy
Direct Laryngoscopy samer kareem 7,406 Views • 2 years ago

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.

Febrile Seizures In Infants
Febrile Seizures In Infants samer kareem 5,007 Views • 2 years ago

A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child's having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity. Febrile seizures represent a unique response of a child's brain to fever, usually the first day of a fever. Fortunately, they're usually harmless and typically don't indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.

Encopresis is a problem that children age four or older can develop due to chronic (long-term) constipation. With constipation, children have fewer bowel movements than normal, and the bowel movements they do have can be hard, dry, and difficult to pass. The child may avoid using the bathroom to avoid discomfort.

Defibrillation is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT). A defibrillator delivers a dose of electric current (often called a countershock) to the heart.

Laparoscopic cervical cerclage
Laparoscopic cervical cerclage samer kareem 31,554 Views • 2 years ago

Cervical cerclage can be placed via transvaginal, open transabdominal, or laparoscopic transabdominal approach, preferably before pregnancy. Recurrent late miscarriages may be due to a weak (sometimes called an incompetent) cervix that shortens or opens too early in pregnancy. Cervical cerclage involves placing a stitch around the upper part of the cervix to keep it closed; the operation may be carried out through the vagina, or through the abdomen, as an open or laparoscopic ('keyhole') procedure.

Meckel's Diverticulum
Meckel's Diverticulum samer kareem 5,808 Views • 2 years ago

The differential diagnosis for this child's painless hematochezia includes Meckel's diverticulum as well as vascular malformations. Meckel's diverticulum results from a failure of the vitelline duct to obliterate during the first 8 weeks of gestation, leaving behind a blind pouch often containing ectopic gastric tissue. Meckel's diverticulum classically affects children age ~:2 but can also occur in older children or even adults. Young children are more likely to experience painless bleeding due to mucosal irritation from gastric acid; adolescents and adults are more likely to have signs of obstruction. A technetium-99 nuclear scan will identify the diverticulum, which is usually located in the right lower quadrant of the abdomen within 2 feet of the ileocecal valve. Technetium-99 concentrates in the parietal cells of the diverticulum and stomach. The scan is also known as "Meckel's scan" due to its high specificity. A symptomatic Meckel's diverticulum is generally treated with surgical resection.
