Leukemia cutis is an infiltration of the skin by myeloid or lymphoid neoplastic leukocytes resulting in clinically identifiable cutaneous lesions. It may follow, precede, or occur concomitantly with the diagnosis of systemic leukemia. A 55-year-old female patient was a known case of acute myeloid leukemia (AML) and was on palliative chemotherapy. She presented to the Department of Dermatology with sudden-onset nodules over the chest and abdomen which were multiple, nontender and firm in consistency. Histopathological examination from the nodule over the abdomen suggested leukemic infiltration of the skin and repeat hemogram showed reappearance of blast cells in the peripheral smear, consistent with a diagnosis of leukemia cutis with relapsed AML. The case has been reported for its rarity and poor prognosis associated with its presentation.

Herpes zoster (HZ) or shingles is a viral infection with segmental eruption due to reactivation of varicella zoster virus (VZV) from the dorsal root ganglion. HZ is uncommon in immunocompetent children and early adult life. Incidence increases in individuals over the age of 50 years. However, zoster can occur in childhood following intrauterine infection or exposure to VZV at an early age. We report this case, as HZ is rare in infants, especially HZ ophthalmicus due to both intrauterine infection and exposure after birth.

Over recent epoch, initial uplink synchronization has become an essential part of the wireless communication systems owing to its amenities in the identification of new users to originate communication. Yet, allocating and sharing resources to users is a bottleneck due to the interference caused by multiple users. Besides, preceding works didn't concentrate on the usage of an effective mechanism to estimate the parameters of the received signal in the multiuser synchronization environment. These downsides affect the throughput and spectrum efficiency of the designed OFDMA system. To address these bottlenecks, this paper proposes the Joint Initial Uplink Synchronization and Interference Aware Resource Allocation (JIUS-IRA) in the Multi-User OFDMA system. JIUS-IRA comprises four processes: Parameter Estimation, Optimum Antenna Selection, Resource Allocation, and Resource Sharing. Initially, JIUS-IRA executes the Fast Block Least Mean Square-based Parameters Estimation Scheme (FBLMS-PES) to estimate the user parameters. To reduce the power consumption during transmission between 5G MIMO base station and users, JIUS-IRA selects the optimal antenna for transmission. The Sign Rank Oriented Resource Allocation (SO-RA) method is executed to allocate sub-channel resources to the cellular user. The resource requirement of D2D users present in the OFDMA system is resolved via the Harris Hawks Optimizer based Resource Sharing Scheme (H2ORSS). The numerical results acquired from the simulation are highly confidential with regard to metrics Root Mean Square Error (RMSE) of timing estimation (∼0.006), RMSE of power estimation (∼0.0079), RMSE of frequency estimation (∼ 0.008), Throughput (∼95%), Spectrum Efficiency (∼11.9 bps), and Complexity (0.045 × 104).

Subacute cutaneous lupus erythematosus (SCLE) is a type of lupus erythematosus having distinct characteristic clinical, serologic, and genetic features. Other than the commonly occurring papulosquamous and annular polycyclic lesion, rarely it may present as erythema multiformae, toxic epidermo necrolysis like lesion (Rowell syndrome), erythroderma, and generalized poikiloderma. Herein, we report a case of SCLE presenting as erythroderma.
